281,383 | <p>As the title suggests, I am having trouble maintaining my code on postback. I have a bunch of jQuery code in the Head section and this works fine until a postback occurs after which it ceases to function! </p>
<p>How can I fix this? Does the head not get read on postback, and is there a way in which I can force this to happen? </p>
<p>JavaScript is:</p>
<pre class="lang-html prettyprint-override"><code> <script type="text/javascript">
$(document).ready(function()
{
$('.tablesorter tbody tr').tablesorter();
$('.tablesearch tbody tr').quicksearch({
position: 'before',
attached: 'table.tablesearch',

labelText: 'Search:',
delay: 100
});
});

281,398 | <p>I have an existing web app that allows users to "rate" items based on their difficulty. (0 through 15). Currently, I'm simply taking the average of each user's opinion and presenting the average straight from MySQL. However, it's becoming clear to me (and my users) that weighting the numbers would be more appropriate.</p>
<p>Oddly enough, a few hours of Google-ing hasn't turned up much. I did find two articles that showed site-wide ratings systems based off of "Bayesian filters" (which I partially understand). <a href="http://v3.siteframe.org/document.php?id=595" rel="nofollow noreferrer">Here</a>'s one example:</p>
<blockquote>
<p>The formula is:</p>
<p>WR=(V/(V+M)) * R + (M/(V+M)) * C</p>
<p>Where:</p>
<pre><code>* WR=Weighted Rating (The new rating)
* R=Average Rating (arithmetic mean) so far
* V=Number of ratings given
* M=Minimum number of ratings needed
* C=Arithmetic mean rating across the whole site
</code></pre>
</blockquote>
<p>I like the idea here of ramping up the weighting based on the total number of votes per item...however, because the difficulty levels on my site can range drastically from item to item, taking "C" (arithmetic mean rating across the whole site) is not valid. </p>
<p>so, a restate of my question:</p>
<p>Using MySQL, PHP, or both, I'm try to get from aritmetic mean:</p>
<pre><code>(5 + 5 + 4)/3 = 4.67 (rounded)
</code></pre>
<p>...to a weighted mean:</p>
<pre><code>rating / weight
5 / 2 (since it was given 2 times)
5 / 2
4 / 1
(sum[(rate * weight)])/(sum of weights)
(5 * 2) + (5 * 2) + (4 * 1) / (2 + 2 + 1)
(24)/(5)
= 4.8
</code></pre>

281,418 | <p>I am using the standard .Net 2.0 DataGridView with sort mode of automatic on the column. It is very very slow (which should probably be another question on how to speed it up) but I can't seem to find an event or combination of events that will maintain a WaitCursor while this sort operation is being performed.</p>

281,436 | <p>I have a SSRS 2005 report that has a number of images in it. The way that I have the images included is I have an image object with the URL set in the value property. The actual images are hosted by an IIS virtual directory on the same server. I'm doing it this way because I need to dynamically change the image source using an expression depending on the data within the report. </p>
<p>The problem is that the images work great when previewing the report in Visual Studio but do not display when the report is deployed. When I look at the HTML rendered by SSRS the SRC attribute of the image tag is an empty string.</p>

281,443 | <p>The following source code alerts the following results:</p>
<p><strong>Internet Explorer 7</strong>: 29<br>
<strong>Firefox 3.0.3</strong>: 37 (correct)<br>
<strong>Safari 3.0.4 (523.12.9)</strong>: 38<br>
<strong>Google Chrome 0.3.154.9</strong>: 38 </p>
<p>Please ignore the following facts: </p>
<ul>
<li>Webkit (Safari/Chrome) browsers insert an extra text node at the end of the body tag</li>
<li>Internet Explorer doesn't have new lines in their whitespace nodes, like they should.</li>
<li>Internet Explorer has no beginning whitespace node (there is obvious whitespace before the <form> tag, but no text node to match)
</ul>
<p>Of the tags in the test page, the following tags have no whitespace text nodes inserted in the DOM after them: <code>form</code>, <code>input[@radio]</code>, <code>div</code>, <code>span</code>, <code>table</code>, <code>ul</code>, <code>a</code>.</p>
<p>My question is: <strong>What is it about these nodes that makes them the exception in Internet Explorer?</strong> Why is whitespace not inserted after these nodes, and is inserted in the others? </p>
<p>This behavior is the same if you switch the tag order, switch the doctype to XHTML (while still maintaining standards mode).</p>
<p>Here's a <a href="http://www.howtocreate.co.uk/wrongWithIE/?chapter=Empty+Space" rel="noreferrer">link that gives a little background information</a>, but no ideal solution. There might not be a solution to this problem, I'm just curious about the behavior.</p>

281,456 | <p>I need to convert several Java classes to C#, but I have faced few problems.</p>
<p>In Java I have following class hierarchy:</p>
<pre><code>public abstract class AbstractObject {
public String getId() {
return id;
}
}
public class ConcreteObject extends AbstractObject {
public void setId(String id) {
this.id= id;
}
}
</code></pre>
<p>There are implementation of AbstractObject which do not need to have setId() defined, so I cannot move it up in the hierarchy.</p>
<p>How to convert this to C# using properties? Is that possible?</p>

281,488 | <p>I have a circular, statically allocated buffer in C, which I'm using as a queue for a <strike>depth</strike> breadth first search. I'd like have the top N elements in the queue sorted. It would be easy to just use a regular qsort() - except it's a circular buffer, and the top N elements might wrap around. I could, of course, write my own sorting implementation that uses modular arithmetic and knows how to wrap around the array, but I've always thought that writing sorting functions is a good exercise, but something better left to libraries.</p>
<p>I thought of several approaches:</p>
<ol>
<li>Use a separate linear buffer - first copy the elements from the circular buffer, then apply qsort, then copy them back. Using an additional buffer means an additional O(N) space requirement, which brings me to
<ul>
<li>Sort the "top" and "bottom" halve using qsort, and then merge them using the additional buffer</li>
<li>Same as 2. but do the final merge in-place (I haven't found much on in-place merging, but the implementations I've seen don't seem worth the reduced space complexity)</li>
</ul></li>
</ol>
<p>On the other hand, spending an hour contemplating how to elegantly avoid writing my own quicksort, instead of adding those 25 (or so) lines might not be the most productive either...</p>
<p><strong>Correction:</strong> Made a stupid mistake of switching DFS and BFS (I prefer writing a DFS, but in this particular case I have to use a BFS), sorry for the confusion.</p>
<p><strong>Further description of the original problem:</strong></p>
<p>I'm implementing a <strong>breadth</strong> first search (for something not unlike the <a href="http://en.wikipedia.org/wiki/Fifteen_puzzle" rel="nofollow noreferrer">fifteen</a> puzzle, just more complicated, with about O(n^2) possible expansions in each state, instead of 4). The "bruteforce" algorithm is done, but it's "stupid" - at each point, it expands all valid states, in a hard-coded order. The queue is implemented as a circular buffer (unsigned queue[MAXLENGTH]), and it stores integer indices into a table of states. Apart from two simple functions to queue and dequeue an index, it has no encapsulation - it's just a simple, statically allocated array of unsigned's.</p>
<p>Now I want to add some heuristics. The first thing I want to try is to sort the expanded child states after expansion ("expand them in a better order") - just like I would if I were programming a simple best-first DFS. For this, I want to take part of the queue (representing the most recent expanded states), and sort them using some kind of heuristic. I could also expand the states in a different order (so in this case, it's not really important if I break the FIFO properties of the queue).</p>
<p>My goal is not to implement <a href="http://en.wikipedia.org/wiki/A*_search_algorithm" rel="nofollow noreferrer">A*</a>, or a depth first search based algorithm (I can't afford to expand all states, but if I don't, I'll start having problems with infinite cycles in the state space, so I'd have to use something like <a href="http://en.wikipedia.org/wiki/Iterative_deepening_depth-first_search" rel="nofollow noreferrer">iterative deepening</a>).</p>

281,500 | <p>I'm trying to connect to an MDF. I've even gone to the lengths of re-installing sql server express entirely (it is now the only flavor of SQL installed on my box, where previously I had 05 dev and express). I've verified that the paths are all correct, and thus far my google-fu hasn't helped.</p>
<p>The Full exception message is: </p>
<blockquote>
<p>Failed to generate a user instance of SQL Server due to a failure in

<p>The Connection string is:</p>

</code></pre>
<h3>Additional info:</h3>
<p>Several of the references to this error I've found online do not apply to me. For example, one I've seen is where this error occurs when trying to start the user instance over remote desktop (I'm doing this locally). While another suggests that it has to do with leftover files from an old express installation ... I've looked in the prescribed locations and not found those artifacts. I also tried running <code>sp_configure 'user instances enabled', '1'</code>, but it said that it was already set to 1.</p>

<p>I have an interface lets call it Account</p>

<p>Now I have two concrete implementors of Account
OverSeasAccount and OverDrawnAccount</p>

<p>AND</p>
<pre><code>public class OverDrawnAccount implements Account {
public void doStuff() {
//do overDrawn type stuff
}
}
</code></pre>
<p>I have a class called Work with a List</p>
<pre><code>private List<Account> accounts;

<p>I am looking at discriminator fields but I seem to be only able do this for abstract classes. Is this the case? Any pointers appreciated. Can I use discriminators for interfaces? </p>

And second, is there a way to defrag both (virtual and physical hard disc) at once?</p>
<p>Thanks in advance!</p>

281,531 | <p>Most of my PHP apps have an ob_start at the beginning, runs through all the code, and then outputs the content, sometimes with some modifications, after everything is done.</p>
<pre><code>ob_start()
//Business Logic, etc
header->output();
echo apply_post_filter(ob_get_clean());
footer->output();
</code></pre>
<p>This ensures that PHP errors get displayed within the content part of the website, and that errors don't interfere with <code>header</code> and <code>session_*</code> calls.</p>
<p>My only problem is that with some large pages PHP runs out of memory. How do I stop this from happening?</p>
<p>Some ideas:</p>
<ol>
<li>Write all of the buffered content to a temporary file and output that.</li>
<li>When the buffers reaches a certain size, output it. Although this might interfere with the post filter.</li>
<li>Raise the memory limit (thanx @troelskn).</li>
</ol>
<p>Whats the drawbacks on each of these approaches? Especially raising the memory limit?</p>

281,534 | <p>Grasping at straws here... I work with a VB6 desktop system using several 2003-style Access databases (.MDB). Recently, I changed the first function from VB6 to VB.NET, still using an Access database. This is more than a conversion, but a rewrite with additional functionality. It is still fairly simple functionality, with a low-volume database. We have 1400 customers, small businesses with varying machine qualities. Most customers are happy with the new screen and functionality. A very few of those customers have experienced EXTREME slowness loading the datagridview. Customer Service tells us that 1) the machines have at least 1 GB of RAM, and 2) rebooting always solves the problem. </p>
<p>I wrote an app to severely slow down my machine, and it STILL runs better for me than it does for those few customers. Also, my Access database has never been trashed by this application. </p>
<p>Any suggestions?</p>
<p>Thanks!!</p>

281,563 | <p>I'm currently using AntLR to parse some files with a proprietary language.
I have a need of highlighting sections of it on an editor (think of highlighting a method in a Java class, for instance).</p>
<p>Does anyone has a hint on how to get them?
Say I have this code:</p>
<pre><code>function test(param1, param2) {
}
</code></pre>
<p>as function is a keyword, the first position I get in the parser is the one of the identifier "test". How can I get the positions from there up to the ending curly brace? The parameters list is dynamic, as one would expect, so you don't know in advance its length.</p>
<p>Thank you!</p>

281,579 | <p>I'm trying to do Ruby password input with the <a href="http://highline.rubyforge.org/" rel="noreferrer">Highline gem</a> and since I have the user input the password twice, I'd like to eliminate the duplication on the blocks I'm passing in. For example, a simple version of what I'm doing right now is:</p>
<pre><code>new_pass = ask("Enter your new password: ") { |prompt| prompt.echo = false }
verify_pass = ask("Enter again to verify: ") { |prompt| prompt.echo = false }
</code></pre>
<p>And what I'd like to change it to is something like this:</p>
<pre><code>foo = Proc.new { |prompt| prompt.echo = false }
new_pass = ask("Enter your new password: ") foo
verify_pass = ask("Enter again to verify: ") foo

<p>Which unfortunately doesn't work. What's the correct way to do this?</p>

281,584 | <p>Using an ORM approach in applications can often lead to the scenario where you have a collection of objects you've retrieved and would like to display them in a tabular view using a DataGridView.</p>
<p>In my (limited) experience, binding collections of objects using a custom BindingList to a DataGridView results in poor performance and unsatisfactory sorting. I'm looking for a generic solution to this problem such that it's straightforward to populate a DataGridView and also extract the underlying objects later.</p>
<p>I will describe a good solution I've found, but I'm looking for alternatives.</p>

281,627 | <p>I have a flex client that makes service calls to a tomcat server running BlazeDS. I would like to gracefully handle server session timeouts in this environment.</p>
<p>I do have security constraints on the service, so the client authenticates against a remote object by initializing a ChannelSet based on the destination, and then logging in using that ChannelSet.</p>
<p>After the user is authenticated, if they go get a (long) cup of coffee, their session will inevitably time out.</p>
<p>I would like the client to detect the timeout, and return the user back to the login page, with the appropriate informational messages.</p>
<p>But I am having difficulty finding the best way to detect this timeout from the client. Is it possible, or must I have the server throw an error when the timeout occurs?</p>
<p>Thanks!</p>

281,664 | <p>Imagine the following scenario - we have Page1 which contains controls Control A and Control B.</p>
<p>Say Control A has a button, and on the click of this button we want Control B to react.
But we want to do this in an abstract fashion, i.e. we can't have Control B knowing anything about Control A, and vice versa.</p>
<p>That way we can develop these controls in isolation, and drive them by unit-testing.</p>
<p>Now, I thought I had the solution, just want to know what you guys think of it.</p>
<p>On Control A's button click, I put a 'message' on the Session, i.e. Session["MESSAGES"] = "ControlA_Click".</p>
<p>In Page1, on the Page_LoadComplete(), I put a call to ProcessMessages, which looks like this:</p>
<pre><code> List<Message> messages = SessionMessages.GetMessageList(Page);
foreach(Message m in messages)
{
//Get Controls
ControlA controlA = FindControl("controlA") as ControlA;
controlA .ProcessMessage(m);
ControlB controlB = FindControl("controlB") as ControlB;
controlB.ProcessMessage(m);
}
</code></pre>
<p>in ControlB's ProcessMessage() method, we can react to the messages that ControlB is interested in, like so:</p>
<pre><code> if (m.MessageName == SessionMessages.C_MESSAGE_SEARCH)
{
this.Visible = true;
}
</code></pre>
<p>To me, this seems to work. It allows us to develop these controls completely separately from eachother, while still allowing for inter-control-communication at an abstract level.</p>
<p>The only thing I can think of that might bring this crashing down is <em>perhaps</em> the ASP.NET life-cycle in relation to Pages and User Controls. The way I figure it though is that ALL events should have been processed on the controls before Page_LoadComplete() is called on the owning Page.</p>
<p>Thoughts?</p>

281,725 | <p>I want to make this specialized w/o changing main. Is it possible to specialize something based on its base class? I hope so.</p>
<p>-edit-</p>
<p>I'll have several classes that inherit from SomeTag. I don't want to write the same specialization for each of them.</p>
<pre><code>class SomeTag {};
class InheritSomeTag : public SomeTag {};
template <class T, class Tag=T>
struct MyClass
{
};
template <class T>
struct MyClass<T, SomeTag>
{
typedef int isSpecialized;

int main()
{
MyClass<SomeTag>::isSpecialized test1; //ok
MyClass<InheritSomeTag>::isSpecialized test2; //how do i make this specialized w/o changing main()
return 0;
}

281,743 | <p>I have a client which is shipping via UPS, and therefore cannot deliver to Post Office boxes. I would like to be able to validate customer address fields in order to prevent them from entering addresses which include a PO box. It would be best if this were implemented as a regex so that I could use a client-side regex validation control (ASP.NET).</p>
<p>I realize there's probably no way to get a 100% detection rate, I'm just looking for something that will work most of the time.</p>

281,744 | <p>Can someone explain how exactly prepared connection pooling using dbcp can be used? (with some example code if possible). I've figured out how to turn it on - passing a KeyedObjectPoolFactory to the PoolableConnectionFactory.
But how should the specific prepared statements be defined after that?
Right now I'm only using a PoolingDataSource to get connections from the pool. How do I use the prepared statements from the pool?</p>

281,758 | <p>I'm working on a Spring MVC project, and I have unit tests for all of the various components in the source tree.</p>
<p>For example, if I have a controller <code>HomeController</code>, which needs to have a <code>LoginService</code> injected into it, then in my unit test <code>HomeControllerTest</code> I simply instantiate the object as normal (outside of Spring) and inject the property:</p>
<pre><code>protected void setUp() throws Exception {
super.setUp();
//...
controller = new HomeController();
controller.setLoginService( new SimpleLoginService() );
//...
}
</code></pre>
<p>This works great for testing each component as an isolated unit - except now that I have a few dozen classes in the project, after writing a class and writing a successful unit test for it, I keep forgetting to update my Spring MVC context file that does the actual wiring-up in the deployed application. I find out that I forgot to update the context file when I deploy the project to Tomcat and find a bunch of NullPointers from non-wired-up beans.</p>
<p>So, here are my questions:</p>
<ol>
<li><p>This is my first Spring project - is it normal to create unit tests for the individual beans, as I have done, and then create a second suite of tests (integration tests) to test that everything works as expected with the actual application context? Is there an established best practice for this?</p></li>
<li><p>In addition, how do you separate the unit tests from the integration tests? I have all of the source code in <code>src</code>, the unit tests in <code>test</code> - should there be a 2nd test folder (such as <code>test-integration</code>) for integration test cases?</p></li>
</ol>
<p>Since this is my first Spring project, I'm curious how others usually go about doing this sort of thing - and rather than re-invent the wheel I rather ask the rest of the community.</p>

281,787 | <p>What's the best way to output the public contents of an object to a human-readable file? I'm looking for a way to do this that would not require me to know of all the members of the class, but rather use the compiler to tell me what members exist, and what their names are. There have to be macros or something like that, right?</p>
<p>Contrived example: </p>
<pre><code>class Container
{
public:
Container::Container() {/*initialize members*/};
int stuff;
int otherStuff;
};
Container myCollection;
</code></pre>
<p>I would like to be able to do something to see output along the lines of "myCollection: stuff = value, otherStuff = value".
But then if another member is added to Container, </p>
<pre><code>class Container
{
public:
Container::Container() {/*initialize members*/};
int stuff;
string evenMoreStuff;
int otherStuff;
};
Container myCollection;</code></pre>
<p>This time, the output of this snapshot would be "myCollection: stuff = value, evenMoreStuff=value, otherStuff = value"</p>
<p>Is there a macro that would help me accomplish this? Is this even possible? (Also, I can't modify the Container class.)
Another note: I'm most interested about a potential macros in VS, but other solutions are welcome too.</p>

281,791 | <p>I want to set the background of an <code>NSBox</code> to be a gradient. In Interface Builder it is possible to set the background color of an <code>NSBox</code> to <code>selectedMenuColor</code> which is a gradient. </p>
<p><code>NSBox</code> only has a <code>setFillColor</code> method so how is Interface Builder filling it with a gradient? </p>

281,818 | <p>I'm currently working on some logging code that supposed to - among other things - print information about the calling function. This should be relatively easy, standard C++ has a <code>type_info</code> class. This contains the name of the typeid'd class/function/etc. but it's mangled. It's not very useful. I.e. <code>typeid(std::vector<int>).name()</code> returns <code>St6vectorIiSaIiEE</code>.</p>
<p>Is there a way to produce something useful from this? Like <code>std::vector<int></code> for the above example. If it only works for non-template classes, that's fine too.</p>
<p>The solution should work for gcc, but it would be better if I could port it. It's for logging so it's not so important that it can't be turned off, but it should be helpful for debugging.</p>

281,831 | <p>I am porting an MFC application to .NET WinForms. In the MFC application, you can right click on a menu or on a context menu item and we show another context menu with diagnostic and configuration items. I am trying to port this functionality to .NET, but I am having trouble.</p>
<p>I have been able to capture the right click, disable the click of the underlying menu and pop up a context menu at the right location, but the original menu disappears as soon as it loses focus.</p>
<p>In MFC, we show the new context menu by calling <strong>TrackPopupMenuEx</strong> with the <strong>TPM_RECURSE</strong> flag.</p>
<p><strong>ContextMenu</strong> and the newer <strong>ContextMenuStrip</strong> classes in .NET only have a <em>Show</em> method. Does anyone know how to do this in .NET?</p>
<p><strong>EDIT</strong></p>
<p>I have tried using <strong>TrackPopupMenuEx</strong> through a p/invoke, but that limits you to using a ContextMenu instead of a ContextMenuStrip which looks out of place in our application. It also still does not work correctly. It doesn't work with the new <strong>MenuStrip</strong> and <strong>ContextMenuStrip</strong>.</p>
<p>I have also tried subclassing ToolStripMenuItem to see if I can add a context menu to it. That is working for <strong>MenuStrip</strong>, but <strong>ContextMenuStrip</strong> still allows the right click events to pass through as clicks.</p>

281,866 | <p>Often you need to show a list of database items and certain aggregate numbers about each item. For instance, when you type the title text on Stack Overflow, the Related Questions list appears. The list shows the titles of related entries and the single aggregated number of quantity of responses for each title.</p>
<p>I have a similar problem but needing multiple aggregates. I'd like to display a list of items in any of 3 formats depending on user options:</p>
<ul>
<li>My item's name (15 total, 13 owned by me)</li>
<li>My item's name (15 total)</li>
<li>My item's name (13 owned by me)</li>
</ul>
<p>My database is:</p>
<ul>
<li><strong>items</strong>: itemId, itemName, ownerId</li>
<li><strong>categories</strong>: catId, catName</li>
<li><strong>map</strong>: mapId, itemId, catId</li>
</ul>
<p>The query below gets: category name, count of item ids per category</p>
<pre><code>SELECT
categories.catName,
COUNT(map.itemId) AS item_count
FROM categories
LEFT JOIN map
ON categories.catId = map.catId
GROUP BY categories.catName
</code></pre>
<p>This one gets: category name, count of item ids per category for this owner_id only</p>
<pre><code>SELECT categories.catName,
COUNT(map.itemId) AS owner_item_count
FROM categories
LEFT JOIN map
ON categories.catId = map.catId
LEFT JOIN items
ON items.itemId = map.itemId
WHERE owner = @ownerId
GROUP BY categories.catId
</code></pre>
<p>But how do i get them at the same time in a single query? I.e.: category name, count of item ids per category, count of item ids per category for this owner_id only</p>
<p>Bonus. How can I optionally only retrieve where catId count != 0 for any of these? In trying "WHERE item_count <> 0" I get:</p>
<pre><code>MySQL said: Documentation
#1054 - Unknown column 'rid_count' in 'where clause'
</code></pre>

281,913 | <p>I need to execute a SQL Server system stored procedure, programmatically, and since it executes in the current schema, I need to change it on the fly.</p>
<p>Like this</p>
<p>Statement st = connection.createStatement();
st.execute("EXEC SP_ADDUSER ' ', ' '");</p>
<p>But SP_ADDUSER only executes on the current schema set for the connection, so if I wanted to create users in various schemas, I'd need to change it, and that's what I am looking for.</p>

281,922 | <p>I'm building a program that has a class used locally, but I want the same class to be used the same way over the network. This means I need to be able to make synchronous calls to any of its public methods. The class reads and writes files, so I think XML-RPC is too much overhead. I created a basic rpc client/server using the examples from twisted, but I'm having trouble with the client.</p>
<pre><code>c = ClientCreator(reactor, Greeter)
c.connectTCP(self.host, self.port).addCallback(request)
reactor.run()
</code></pre>
<p>This works for a single call, when the data is received I'm calling reactor.stop(), but if I make any more calls the reactor won't restart. Is there something else I should be using for this? maybe a different twisted module or another framework?</p>
<p>(I'm not including the details of how the protocol works, because the main point is that I only get one call out of this.)</p>
<p>Addendum & Clarification:</p>
<p>I shared a google doc with notes on what I'm doing. <a href="http://docs.google.com/Doc?id=ddv9rsfd_37ftshgpgz" rel="nofollow noreferrer">http://docs.google.com/Doc?id=ddv9rsfd_37ftshgpgz</a></p>
<p>I have a version written that uses fuse and can combine multiple local folders into the fuse mount point. The file access is already handled within a class, so I want to have servers that give me network access to the same class. After continuing to search, I suspect pyro (<a href="http://pyro.sourceforge.net/" rel="nofollow noreferrer">http://pyro.sourceforge.net/</a>) might be what I'm really looking for (simply based on reading their home page right now) but I'm open to any suggestions.</p>
<p>I could achieve similar results by using an nfs mount and combining it with my local folder, but I want all of the peers to have access to the same combined filesystem, so that would require every computer to bee an nfs server with a number of nfs mounts equal to the number of computers in the network.</p>
<p><strong>Conclusion:</strong>
I have decided to use rpyc as it gave me exactly what I was looking for. A server that keeps an instance of a class that I can manipulate as if it was local. If anyone is interested I put my project up on Launchpad (<a href="http://launchpad.net/dstorage" rel="nofollow noreferrer">http://launchpad.net/dstorage</a>).</p>

281,928 | <p>I often find myself writing simple for loops to perform an operation to many files, for example:</p>
<pre><code>for i in `find . | grep ".xml$"`; do bzip2 $i; done
</code></pre>
<p>It seems a bit depressing that on my 4-core machine only one core is getting used.. is there an easy way I can add parallelism to my shell scripting?</p>
<p>EDIT: To introduce a bit more context to my problems, sorry I was not more clear to start with!</p>
<p>I often want to run simple(ish) scripts, such as plot a graph, compress or uncompress, or run some program, on reasonable sized datasets (usually between 100 and 10,000). The scripts I use to solve such problems look like the one above, but might have a different command, or even a sequence of commands to execute.</p>
<p>For example, just now I am running:</p>
<pre><code>for i in `find . | grep ".xml.bz2$"`; do find_graph -build_graph $i.graph $i; done
</code></pre>
<p>So my problems are in no way bzip specific! (Although parallel bzip does look cool, I intend to use it in future).</p>

281,933 | <p>Given a word, I've to replace some specific alphabets with some specific letters such as 1 for a, 5 for b etc. I'm using regex for this. I understand that StringBuilder is the best way to deal with this problem as I'm doing a lot of string manipulations. Here is what I'm doing:</p>
<pre><code>String word = "foobooandfoo";
String converted = "";
converted = word.replaceAll("[ao]", "1");
converted = converted.replaceAll("[df]", "2");
converted = converted.replaceAll("[n]", "3");
</code></pre>
<p>My problem is how to rewrite this program using StringBuilder. I tried everything but I can't succeed. Or using String is just fine for this?</p>

281,945 | <p>Does anyone know of a way to store values as NVARCHAR in a manually created query in ColdFusion using the querynew() function? I have multiple parts of a largish program relying on using a query as an input point to construct an excel worksheet (using Ben's POI) so it's somewhat important I can continue to use it as a query to avoid a relatively large rewrite.</p>
<p>The problem came up when a user tried storing something that is outside of the VARCHAR range, some Japanese characters and such.</p>
<p>Edit: If this is not possible, and you are 100% sure, I'd like to know that too :)</p>

281,979 | <p>Do you generate your data dictionary? If so, how?</p>
<p>I use extended procedures in SQL Server 2005 to hold onto table and field information. I have some queries that create a dictionary out of them, but it's ... meh. Do you have a particular query or tool you use? Do you generate it off of your database diagrams?</p>
<p>Googling for "data dictionary sql server" comes up with many queries, but they're all about equally as attractive. Which is to say, good starting off points, but not production ready.</p>

282,002 | <p>In developing search for a site I am building, I decided to go the cheap and quick way and use Microsoft Sql Server's Full Text Search engine instead of something more robust like Lucene.Net.</p>
<p>One of the features I would like to have, though, is google-esque relevant document snippets. I quickly found determining "relevant" snippets is more difficult than I realized. </p>
<p>I want to choose snippets based on search term density in the found text. So, essentially, I need to find the most search term dense passage in the text. Where a passage is some arbitrary number of characters (say 200 -- but it really doesn't matter).</p>
<p>My first thought is to use .IndexOf() in a loop and build an array of term distances (subtract the index of the found term from the previously found term), then ... what? Add up any two, any three, any four, any five, sequential array elements and use the one with the smallest sum (hence, the smallest distance between search terms).</p>
<p>That seems messy.</p>
<p>Is there an established, better, or more obvious way to do this than what I have come up with?</p>

282,014 | <p>I have an object that starts a thread, opens a file, and waits for input from other classes. As it receives input, it writes it to disk. Basically, it's a thread safe data logging class...</p>
<p>Here's the weird part. When I open a form in the designer (Visual Studio 2008) that uses the object the file gets created. It's obviously running under the design time vhost process...</p>
<p>The odd thing is I've not been able to reproduce the issue in another project. I'm not sure what the rules are for code that gets executed in the designer and code that does not. For example, creating a file in a Windows Forms constructor doesn't actually create the file at design time...</p>

282,016 | <p>I need to make a piece of C# code interact through COM with all kinds of implementations.</p>
<p>To make it easeier for users of that integration, I included the interacted interfaces in IDL (as part of a relevant existing DLL, but without coclass or implementation), then got that into my C# code by running Tlbimp to create the types definition.</p>
<p>I implemented my C#, creating COM objects based on Windows registry info and casting the object into the interface I need.</p>
<p>I then created a C# implementation of the interface in a seperate project and registered it.
The main program creates the testing COM object correctly but fails to cast it into the interface (gets a null object when using C# 'as', gets an InvalidCastException of explicit cast).</p>
<p>Can someone suggest why the interface is not identified as implemented by the testing object?</p>
<p>This is the interface defition in IDL (compiled in C++ in VS 2005):</p>
<pre><code> [
object,
uuid(B60C546F-EE91-48a2-A352-CFC36E613CB7),
dual,
nonextensible,
helpstring("IScriptGenerator Interface"),
pointer_default(unique)
]
interface IScriptGenerator : IDispatch{
[helpstring("Init the Script generator")]
HRESULT Init();
[helpstring("General purpose error reporting")]
HRESULT GetLastError([out] BSTR *Error);
};
</code></pre>
<p>This is the stub created for C# by Tlbimp:</p>
<pre><code>[TypeLibType(4288)]
[Guid("B60C546F-EE91-48A2-A352-CFC36E613CB7")]
public interface IScriptGenerator
{
[DispId(1610743813)]
void GetLastError(out string Error);
[DispId(1610743808)]
void Init();
}
</code></pre>
<p>This is part of the main C# code, creating a COM object by its ProgID and casting it to the IScriptGenerator interface:</p>
<pre><code>public ScriptGenerator(string GUID)
{
Type comType = Type.GetTypeFromProgID(GUID);
object comObj = null;
if (comType != null)
{
try
{
comObj = Activator.CreateInstance(comType);
}
catch (Exception ex)
{
Debug.Fail("Cannot create the script generator COM object due to the following exception: " + ex, ex.Message + "\n" + ex.StackTrace);
throw ex;
}
}
else
throw new ArgumentException("The GUID does not match a registetred COM object", "GUID");
m_internalGenerator = comObj as IScriptGenerator;
if (m_internalGenerator == null)
{
Debug.Fail("The script generator doesn't support the required interface - IScriptGenerator");
throw new InvalidCastException("The script generator with the GUID " + GUID + " doesn't support the required interface - IScriptGenerator");
}
}
</code></pre>
<p>And this is the implementing C# code, to test it's working (and it's not):</p>
<pre><code> [Guid("EB46E31F-0961-4179-8A56-3895DDF2884E"),
ProgId("ScriptGeneratorExample.ScriptGenerator"),
ClassInterface(ClassInterfaceType.None),
ComSourceInterfaces(typeof(SOAAPIOLELib.IScriptGeneratorCallback))]
public class ScriptGenerator : IScriptGenerator
{
public void GetLastError(out string Error)
{
throw new NotImplementedException();
}
public void Init()
{
// nothing to do
}
}

282,018 | <p>I'm doing some maintenance on a private svn server. Authentication is handled through Apache basic HTTP+mod_authz_svn. I need to have it so every user has read/write access, except for a single read-only user. The read-only user still needs to be authenticated, though. I setup my authz config file like this:</p>

* = rw
read-only = r</pre>
<p>But this doesn't work. The user "read-only" can still commit changes. I can make things read-only for everyone, but the * bit seems to override what I'm trying to set for "read-only."</p>
<p>FWIW, relevant piece of the Apache conf is:</p>
<pre> <Location /repos>
DAV svn
SVNPath ...
SVNIndexXSLT "/svnindex.xsl"
AuthzSVNAccessFile ...
AuthType Basic
AuthName ...
AuthUserFile ...

282,019 | <p>I would like to declare a record in Delphi that contains the same layout as it has in C.</p>
<p>For those interested : This record is part of a union in the Windows OS's LDT_ENTRY record. (I need to use this record in Delphi because I'm working on an Xbox emulator in Delphi - see project Dxbx on sourceforge).</p>
<p>Anyway, the record in question is defined as:</p>
<pre><code> struct
{
DWORD BaseMid : 8;
DWORD Type : 5;
DWORD Dpl : 2;
DWORD Pres : 1;
DWORD LimitHi : 4;
DWORD Sys : 1;
DWORD Reserved_0 : 1;
DWORD Default_Big : 1;
DWORD Granularity : 1;
DWORD BaseHi : 8;
}
Bits;
</code></pre>
<p>As far as I know, there are no bit-fields possible in Delphi. I did try this:</p>
<pre><code> Bits = record
BaseMid: Byte; // 8 bits
_Type: 0..31; // 5 bits
Dpl: 0..3; // 2 bits
Pres: Boolean; // 1 bit
LimitHi: 0..15; // 4 bits
Sys: Boolean; // 1 bit
Reserved_0: Boolean; // 1 bit
Default_Big: Boolean; // 1 bit
Granularity: Boolean; // 1 bit
BaseHi: Byte; // 8 bits
end;
</code></pre>
<p>But alas: it's size becomes 10 bytes, instead of the expected 4.
I would like to know how I should declare the record, so that I get a record with the same layout, the same size, and the same members. Preferrably without loads of getter/setters.</p>
<p>TIA.</p>

282,035 | <p>How does one lock the focus of a .net application to a specific control? For example, if I have a form with 5 text boxes, and I want them filled out in a specific order, how can I stop someone who is in box 1 from tabbing/clicking to box 2, or hitting OK or Cancel or anything else? Is there an easy way, or do I have to manually disable/enable each other control at the appropriate time? </p>
<p>The trouble with the obvious solution (Reset Focus when Focus is Lost) is that MSDN says you can lock up your machine that way:</p>
<p>(Source:<a href="http://msdn.microsoft.com/en-us/library/system.windows.forms.control.leave.aspx" rel="nofollow noreferrer">http://msdn.microsoft.com/en-us/library/system.windows.forms.control.leave.aspx</a>)</p>
<p>Caution:</p>

282,061 | <p>I have a bit of a problem. I wrote an API a long time ago for our production system, and it used Apache XML Beans. The schema was homogeneous (ie no imports, everything was from within the same schema), and everything worked just fine, even if the code for API handling was incredibly verbose. I've since written a far simpler and more elegant restful API using JAXB, with parts of the old one in mind, ie different schema, but some of the elements are identical. In the hopes of cleaning up and simplifying my binding code in the old API, I've replaced some of the parts by deleting them and importing the new schema and using those elements instead. However, whenever I try to parse documents that use the new mixture of schema, I get a validation error from XML Beans :</p>
<pre><code>error: cvc-complex-type.2.4a: Expected element 'redundant-element@http://www.my.com/old/xmlns' instead of 'redundant-element@http://www.my.com/new/xmlns' here in element redundant-element-list@http://www.my.com/old/xmlns
</code></pre>
<p>Has anybody encountered this before ? Have any solutions or ideas ? I'd really appreciate it. Thank you kindly.</p>

282,062 | <p>I have a class like this:</p>
<pre><code>public class Stretcher : Panel {
public static readonly DependencyProperty StretchAmountProp = DependencyProperty.RegisterAttached("StretchAmount", typeof(double), typeof(Stretcher), null);
public static void SetStretchAmount(DependencyObject obj, double amount)
{
FrameworkElement elem = obj as FrameworkElement;
elem.Width *= amount;
obj.SetValue(StretchAmountProp, amount);
}
}
</code></pre>
<p>I can set the stretch amount property in XAML using the attribute syntax:</p>
<pre><code><UserControl x:Class="ManagedAttachedProps.Page"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:map="clr-namespace:ManagedAttachedProps"
Width="400" Height="300">
<Rectangle Fill="Aqua" Width="100" Height="100" map:Stretch.StretchAmount="100" />
</UserControl>
</code></pre>
<p>and my rectangle is stretched, but I can't use property element syntax like this:</p>
<pre><code><UserControl x:Class="ManagedAttachedProps.Page"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:map="clr-namespace:ManagedAttachedProps"
Width="400" Height="300">
<Rectangle Fill="Aqua" Width="100" Height="100">
<map:Stretcher.StretchAmount>100</map:Stretcher.StretchAmount>
</Rectangle>
</UserControl>
</code></pre>
<p>with the property element syntax my set block seems to be totally ignored (I can even put invalid double values in there), and the SetStretchAmount method is never called.</p>
<p>I know it's possible to do something like this, because VisualStateManager does it. I've tried using types other than double and nothing seems to work.</p>

282,084 | <p>Help!</p>
<p>I have a PHP (PHP 5.2.5) script on HOST1 trying to connect to an MySql database HOST2. Both hosts are in Shared Host environments controlled through CPanel.</p>
<p>HOST2 is set to allow remote database connections from HOST1.</p>
<p>The PHP connect I'm using is:-
$h2 = IPADDRESS;
$dbu = DBUSER;
$dbp = DBPASS;</p>
<pre><code>$DBlink = mysql_connect($h2, $dbu, $dbp);
</code></pre>
<p>This always fails with:-</p>
<pre><code>Access denied for user '<dbusername>'@'***SOMESTRING***' (using password: YES)
</code></pre>
<p>nb: <strong><em>SOMESTRING</em></strong> looks like it could be something to do with the shared host environment.</p>
<p>Any ideas???</p>
<p>BTW: I can make remote connections to HOST2 from my laptop using OpenOffice via ODBC, and SQLyog. The SQLyog and ODBC settings are exactly the same as the PHP script is trying to use.</p>

282,091 | <p>I am instantiating a local COM server using CoCreateInstance. Sometimes the application providing the server takes a long time to start. When this happens, Windows pops a dialog box like this:</p>
<p><strong>Server Busy</strong></p>
<p>The action cannot be completed because the other program is busy. Choose 'Switch To' to activate the busy program and correct the problem.</p>
<p>[Switch To...] [Retry] [Cancel]</p>
<p>I have found mention of a Visual Basic property on the Application object, OleRequestPendingTimeout, that can be used to control the time before this dialog comes up. I can't find any good documentation on this or an equivalent that is useful from C++. Can anyone point me in the right direction?</p>

282,093 | <p>I want my php script to create an output file in a folder based on the date. The way I'm doing this is that its supposed to get the foldername/filename from a text file outputted by another program which I am unable to edit.</p>
<p>So the file its grabbing the data from looks like this:</p>
<pre><code>data/newfolder/10302008/log_for_Today.txt | 24234234
</code></pre>
<p>Only with multiple lines, I just need the script to go through it line by line, grab the folder/filename and create an empty file with that name in that location.</p>
<p>The directories are all 777. Now I know how to create a new empty exe file in a folder but can't seem to figure out how to create the folder first then the exe inside of it, any ideas?</p>

282,105 | <p>I've used a Continuous Integration server in the past with great success, and hadn't had the need to ever perform a code freeze on the source control system. </p>
<p>However, lately it seems that everywhere I look, most shops are using the concept of code freezes when preparing for a release, or even a new test version of their product. This idea runs even in my current project.</p>
<p>When you check-in early and often, and use unit tests, integration tests, acceptance tests, etc., are code freezes still needed?</p>

282,127 | <p>I've got three (relevant) models, specified like this:</p>
<pre><code>class User < ActiveRecord::Base
has_many :posts
has_many :comments
has_many :comments_received, :through => :posts, :source => :comments
end
class Post < ActiveRecord::Base
belongs_to :user
has_many :comments
end
class Comment < ActiveRecord::Base
belongs_to :user
belongs_to :post
end
</code></pre>
<p>I'd like to be able to reference all the <code>comments_received</code> for a <code>user</code> with a route - let's say it's for batch approval of comments on all posts. <em>(note that you can also get <code>comments</code> made by the <code>user</code>, but users can't comment on their own posts, so the <code>comments</code> through a <code>post</code> are different and mutually exclusive)</em>. Logically, this should work with:</p>
<pre><code>map.resources :users, :has_many => [:posts, :comments, :comments_received]
</code></pre>
<p>This should give me routes of</p>
<pre><code>user_posts_path
user_comments_path
user_comments_received_path
</code></pre>
<p>The first two work, the last one doesn't. I've tried it without the <code>_</code> in <code>comments_received</code> to no avail. I'm looking to get a URL like</p>
<pre><code>http://some_domain.com/users/123/comments_received
</code></pre>
<p>I've also tried nesting it, but maybe I'm doing that wrong. In that case, I'd think the map would be:</p>
<pre><code>map.resources :users do |user|
user.resources :comments
user.resources :posts, :has_many => :comments
end
</code></pre>
<p>and then the url might be:</p>
<pre><code>http://some_domain.com/users/123/posts/comments
</code></pre>
<p>Maybe this is the right way to do it, but I have the syntax wrong?</p>
<p>Am I thinking about this the wrong way? It seems reasonable to me that I should be able to get a page of all the <code>comments</code> added to all of a user's posts. </p>
<p>Thanks for your help!</p>

282,146 | <p>I have been given the task of modifying a VB6 project. Nothing incredibly serious, adding a couple forms and fixing a few bugs for the most part. The project uses SQL Server (if that is of any relevance).</p>
<p>My background in programming has been VB/C# .NET, PHP, C++ and mostly MySQL although I have used SQL Server on a much smaller scale. What kind of advice can anyone give me or resources for VB6 programming. It's been a few years since I've done any VB .NET work and while I can read the VB6 code and understand what is going on, I'm not sure how well I'm going to be able to start writing and/or modifying without a chance of breaking anything. </p>
<p>What kind of advice can others offer? Any resources and/or stories would be great. Feel free to contribute things you may feel relevant yet I neglected to mention.</p>

282,176 | <p>Imagine I have a process that starts several child processes. The parent needs to know when a child exits.</p>
<p>I can use <code>waitpid</code>, but then if/when the parent needs to exit I have no way of telling the thread that is blocked in <code>waitpid</code> to exit gracefully and join it. It's nice to have things clean up themselves, but it may not be that big of a deal.</p>
<p>I can use <code>waitpid</code> with <code>WNOHANG</code>, and then sleep for some arbitrary time to prevent a busy wait. However then I can only know if a child has exited every so often. In my case it may not be super critical that I know when a child exits right away, but I'd like to know ASAP...</p>
<p>I can use a signal handler for <code>SIGCHLD</code>, and in the signal handler do whatever I was going to do when a child exits, or send a message to a different thread to do some action. But using a signal handler obfuscates the flow of the code a little bit.</p>
<p>What I'd really like to do is use <code>waitpid</code> on some timeout, say 5 sec. Since exiting the process isn't a time critical operation, I can lazily signal the thread to exit, while still having it blocked in <code>waitpid</code> the rest of the time, always ready to react. <em>Is there such a call in linux? Of the alternatives, which one is best?</em></p>
<hr>
<p>EDIT:</p>
<p>Another method based on the replies would be to block <code>SIGCHLD</code> in all threads with <code>pthread</code> \ <code>_sigmask()</code>. Then in one thread, keep calling <code>sigtimedwait()</code> while looking for <code>SIGCHLD</code>. This means that I can time out on that call and check whether the thread should exit, and if not, remain blocked waiting for the signal. Once a <code>SIGCHLD</code> is delivered to this thread, we can react to it immediately, and in line of the wait thread, without using a signal handler.</p>

end
end

282,184 | <p>Javascript usage has gotten remarkably more sophisticated and powerful in the past five years. One aspect of this sort of functional programming I struggle with, esp with Javascript’s peculiarities, is how to make clear either through comments or code just what is happening. Often this sort of code takes a while to decipher, even if you understand the prototypal, first-class functional Javascript way. Any thoughts or techniques for making perfectly clear what your code does and how in Javascript?</p>
<p>I've asked this question elsewhere, but haven't gotten much response.</p>

282,191 | <p>in my flex application, I created a Tilelist. In this Tilelist, I am using an ItemRenderer to create a box consisting of an image and an VSlider in each tile. </p>
<p>The tile need to be dragable when you click on the image, but not dragable when you slide the slider. How can I achieve this ? I have been scratching my head searching on Google for one day and I have really no idea.</p>
<p>I look forward to your help.
Thank you.</p>
