231,912 | <p>I was about to add an extra signal handler to an app we have here and I noticed that the author had used <code>sigaction()</code> to set up the other signal handlers. I was going to use <code>signal()</code>. To follow convention I should use <code>sigaction()</code> but if I was writing from scratch, which should I choose?</p>

231,917 | <p>This originally was a problem I ran into at work, but is now something I'm just trying to solve for my own curiosity.</p>
<p>I want to find out if int 'a' contains the int 'b' in the most efficient way possible. I wrote some code, but it seems no matter what I write, parsing it into a string and then using indexOf is twice as fast as doing it mathematically.</p>
<p>Memory is not an issue (within reason), just sheer processing speed.</p>
<p>This is the code I have written to do it mathematically:</p>
<pre><code>private static int[] exponents = {10, 100, 1000, 10000, 100000, 1000000, 10000000, 100000000, 1000000000 };
private static boolean findMatch(int a, int b) {
if (b > a) return false;
if (a == b) return true;
int needleLength = getLength(b);
int exponent = exponents[needleLength];
int subNum;
while (a >= 1) {
subNum = a % exponent;
if (subNum == b)
return true;
a /= 10;
}
return false;
}
private static int getLength(int b) {
int len = 0;
while (b >= 1) {
len++;
b /= 10;
}
return len;
}
</code></pre>
<p>Here's the string method I'm using, which seems to trump the mathematical method above:</p>
<pre><code>private static boolean findStringMatch(int a, int b) {
return String.valueOf(a).indexOf(String.valueOf(b)) != -1;
}
</code></pre>
<p>So although this isn't really required for me to complete my work, I was just wondering if anyone could think of any way to further optimize my way of doing it mathematically, or an entirely new approach altogether. Again memory is no problem, I am just shooting for sheer speed.</p>
<p>I'm really interested to see or hear anything anyone has to offer on this.</p>
<p><strong>EDIT:</strong> When I say contains I mean can be anywhere, so for example, findMatch(1234, 23) == true</p>
<p><strong>EDIT:</strong> For everyone saying that this crap is unreadable and unnecessary: you're missing the point. The point was to get to geek out on an interesting problem, not come up with an answer to be used in production code.</p>

231,937 | <p>I am trying to show and hide an inline element (eg a span) using jQuery.</p>
<p>If I just use toggle(), it works as expected but if I use toggle("slow") to give it an animation, it turns the span into a block element and therefore inserts breaks.</p>
<p>Is animation possible with inline elements? I would prefer a smooth sliding if possible, rather than a fade in.</p>
<pre><code><script type="text/javascript">
$(function(){
$('.toggle').click(function() { $('.hide').toggle("slow") });
});
</script>
<p>Hello <span class="hide">there</span> jquery</p>

231,947 | <p>I have a project that is based on the Navigation Based Application template.
In the AppDelegate are the methods <code>-applicationDidFinishLoading:</code> and <code>-applicationWillTerminate:</code>. In those methods, I am loading and saving the application data, and storing it in an instance variable (it is actually an object-graph).</p>
<p>When the application loads, it loads MainWindow.xib, which has a NavigationConroller, which in turn has a RootViewController. The RootViewController <code>nibName</code> property points to RootView (my actual controller class).</p>
<p>In my class, I wish to refer to the object that I created in the <code>-applicationDidFinishLoading:</code> method, so that I can get a reference to it.</p>
<p>Can anyone tell me how to do that? I know how to reference between objects that I have created programmatically, but I can't seem to figure out to thread my way back, given that the middle step was done from within the NIB file.</p>

232,004 | <p>For the moment the best way that I have found to be able to manipulate DOM from a string that contain HTML is:</p>
<pre><code>WebBrowser webControl = new WebBrowser();
webControl.DocumentText = html;
HtmlDocument doc = webControl.Document;
</code></pre>
<p>There are two problems:</p>
<ol>
<li>Requires the <code>WebBrowser</code> object! </li>
<li>This can't be used with multiple threads; I need something that would work on different thread (other than the main thread).</li>
</ol>
<p>Any ideas?</p>

232,008 | <p>I've been exploring the details of Django for about a week now and like what I see. However I've come upon some.. negativity in relation to fine-grained control of permissions to the CRUD interface.</p>
<p>What I'm writing is an Intranet client management web-app. The organisation is about 6 tiers, and I need to restrict access to client groups based on tiers. Continually expanding. I have a fairly good idea how I'm going to do this, but am not sure if I'll be able to integrate it well into the pre-built admin interface. </p>
<p>I've done absolutely zero Django development otherwise I'd probably have a better idea on whether this would work or not. I probably won't use Django if the generated admin interface is going to be useless to this project - but like I said, there is a heavy reliance on fine-grained custom permissions.</p>
<p>Will Django let me build custom permissions/rules and integrate it seamlessly into the admin CRUD interface?</p>
<p>Update One: I want to use the admin app to minimise the repitition of generating CRUD interfaces, so yes I consider it a must have.</p>
<p>Update Two:</p>
<p>I want to describe the permissions required for this project.</p>
<p>A client can belong to one or many 'stores'. Full time employees should only be able to edit clients at their store (even if they belong to another store). However, they should not be able to see/edit clients at another store. Casuals should only be able to view clients based on what store they are rostered too (or if the casual is logged in as the store user - more likely).</p>
<p>Management above them need to be able to see all employees for the stores they manage, nothing more.</p>
<p>Senior management should be able to edit ALL employees and grant permissions below themselves.</p>
<p>After reading the django documentation, it says you can't (autmoatically) set permissions for a sub-set of a group. Only the entire group. Is it easy enough to mock up your own permissions for this purpose?</p>

232,020 | <p>I am working on a project that I need to use the Infragistics WebGrid control for some lists of data. I am loading the data on the client-side using JavaScript for display on a Map, and then I need to display that same data within multiple WebGrids. All the data available will be displayed in the WebGrids, but only a subset of the data (only that which is currently within view) will be plotted on the Map at any given time. Since I am loading the data using JavaScript/Ajax, I would like to only load it once, and use the same mechanism to populate the WebGrid control with data too.</p>
<p>Does anyone have any tips/pointers on working with the WebGrid completely from within client-side JavaScript/Ajax code?</p>

232,052 | <p>I have an MSBuild task to build a specific project in a solution file. It looks something like this:</p>
<pre><code><Target Name="Baz">
<MSBuild Projects="Foo.sln" Targets="bar:$(BuildCmd)" />
</Target>
</code></pre>
<p>From the command line, I can set my <code>BuildCmd</code> to either <code>Rebuild</code> or <code>Clean</code> and it works as expected:</p>
<blockquote>
<p>msbuild /target:Baz /property:BuildCmd=Rebuild MyMsbuildFile.xml
msbuild /target:Baz /property:BuildCmd=Clean MyMsbuildFile.xml</p>
</blockquote>
<p>But what word do I use to set <code>BuildCmd</code> to in order to just build? I've tried <code>Build</code> and <code>Compile</code> and just leaving it blank or undefined, but I always get an error.</p>
<blockquote>
<p>msbuild /target:Baz /property:BuildCmd=Build MyMsbuildFile.xml
Foo.sln : error MSB4057: The target "bar:Build" does not exist in the project.</p>
<p>msbuild /target:Baz /property:BuildCmd=Compile MyMsbuildFile.xml
Foo.sln : error MSB4057: The target "bar:Compile" does not exist in the project.</p>

232,053 | <p>I'm writing javascript code that is read in as a string and executed via eval() by a firefox extension. Firebug does "see" my script so I am not able to use breakpoints, see objects, etc. </p>
<p>I am currently using Firefox's error console which I'm starting to find limiting. What are my other options? Ideally, I would be able to use Firebug or something similar to it. How do people generally debug Greasemonkey scripts?</p>
<p>I've tried using Lint and other validators, but my script uses a lot of objects and functions provided by the extension environment, making of a lot of the errors reported irrelevant. Also, the output tends to be too nitpicky (focusing of spacing issues, etc). </p>

232,075 | <p>In C and C++ a variable can be marked as <a href="http://en.wikipedia.org/wiki/Volatile_variable" rel="noreferrer"><strong>volatile</strong></a>, which means the compiler will not optimize it because it may be modified external to the declaring object.

<p>My thought was to use <strong>Absolute</strong>, but I wasn't sure, and that may introduce other side effects.</p>

232,078 | <p>I have three projects. One is a WCF Services Project, one is a WPF Project, and one is a Microsoft Unit Testing Project. I setup the WCF Services project with a data object that looks like this:</p>
<pre><code>[DataContract]
public enum Priority
{
Low,
Medium,
High
}
[DataContract]
public struct TimeInfo
{
[DataMember]
public Int16 EstimatedHours { get; set; }
[DataMember]
public Int16 ActualHours { get; set; }
[DataMember]
public DateTime StartDate { get; set; }
[DataMember]
public DateTime EndDate { get; set; }
[DataMember]
public DateTime CompletionDate { get; set; }
}
[DataContract]
public class Task
{
[DataMember]
public string Title { get; set; }
[DataMember]
public string Description { get; set; }
[DataMember]
public Priority Priority { get; set; }
[DataMember]
public TimeInfo TimeInformation { get; set; }
[DataMember]
public Decimal Cost { get; set; }
}
</code></pre>
<p>My contract looks like this:</p>
<pre><code>[ServiceContract]
public interface ITaskManagement
{
[OperationContract]
List<Task> GetTasks();
[OperationContract]
void CreateTask(Task taskToCreate);
[OperationContract]
void UpdateTask(Task taskToCreate);
[OperationContract]
void DeleteTask(Task taskToDelete);
}
</code></pre>
<p>When I try to use the service in either the WPF Application or the Unit Test Project with this code:</p>
<pre><code>var client = new TaskManagementClient();
textBox1.Text = client.GetTasks().ToString();
client.Close();
</code></pre>
<p>I get the following error: "The underlying connection was closed: The connection was closed unexpectedly."</p>
<p>The app.config for the WPF and Unit Test Projects look like this:</p>
<pre><code><system.serviceModel>

</identity>
</endpoint>
</client>
</system.serviceModel>
</code></pre>
<p>and the web.config of the WCF Service looks like this:</p>
<pre><code> <system.serviceModel>
<behaviors>
<serviceBehaviors>
<behavior name="InternetBasedWcfServices.TaskManagementBehavior">
<serviceMetadata httpGetEnabled="true" />

</service>
</services>
</system.serviceModel>
</code></pre>
<p>This is not the first time this has happened, and I'm guessing it is a configuration issue. But each time I've usually just blown away my service and put it back or created a new service project. Then everything works wonderfully. If anyone has any ideas, that would be awesome. Thx.</p>

232,141 | <p>I’m listening to the Hanselminutes Podcast; "StackOverflow uses ASP.NET MVC - Jeff Atwood and his technical team". During the course of the Podcast they are speaking about SQL server and say something along the lines of 'The days of the Stored Procedure are over'. </p>
<p>Now I'm not a DBA but this has taken me a bit by surprise. I always assumed that SPs were the way to go for speed (as they are complied) and security not to mention scalability and maintainability.

232,144 | <p>I have a volunteers_2009 table that lists all the volunteers and a venues table that lists the venues that a volunteer can be assigned to, they are only assigned to one.</p>
<p>What I want to do, is print out the number of volunteers assigned to each venue.</p>
<p>I want it to print out like this:</p>
<p>Name of Venue: # of volunteers</p>
<p>table: volunteers_2009
columns: id, name, <code>venue_id</code></p>
<p>table: venues
columns: id, venue_name</p>
<p>They relate by <code>volunteers_2009.venue_id = venues.id</code></p>
<p>This is what I have but it is not working properly.</p>
<pre><code>$sql = "SELECT venues.venue_name as 'Venue', COUNT(volunteers_2009.id) as 'Number Of
Volunteers' FROM venues ven JOIN volunteers_2009 vol ON
(venues.id=volunteers_2009.venue_id) GROUP BY venues.venue_name ORDER BY
venues.venue_name ASC";
$result = mysql_query($sql);
while(list($name,$vols) = mysql_fetch_array($result)) {

232,161 | <p>I'm currently developing an application that is comprised of five separate executables that communicate via ActiveMQ. I have a Visual Studio Solution that contains the five executable projects. One of the projects (the launcher.exe) launches the other four projects from their local folders as separate processes. As such, the launcher project is set as the "Startup Project" and, as a result, it's the only one I can set break points in and debug due to my limited knowledge of VS2005.</p>
<p>Is there a way to set multiple breakpoints across my five c++ projects in my single VS solution and debug them at the same time if the launcher project is the only project executed from VS? </p>
<p><strong><em>Note:</em></strong> <em>Manually starting new instances of each project via Visual Studio is not an option since their execution needs to be synchronized by the launcher.exe.</em></p>
<p>I apologize if this is convoluted, it's the best I can explain it. Thanks in advance for your help! </p>

232,162 | <p>I have a bunch of C files that are generated by a collection of python programs that have a number of shared python modules and I need to account for this in my make system.</p>
<p>It is easy enough to enumerate which python program need to be run to generate each C file. What I can't find a good solution for is determining which other python files those programs depend on. I need this so make will know what needs regenerating if one of the shared python files changes.</p>
<p>Is there a good system for producing make style dependency rules from a collection of python sources?</p>

232,202 | <p>I was planning to implememt owner-drawn of CListCtrl. I thought that drawing an item is after the item is inserted into the control. So my method is declare a class which is derived from CListCtrl and override its DrawItem() method. The problem is DrawItem is never invoked after inserting an item. Is there anything wrong with my method?</p>
<p>Thank you!</p>

232,212 | <p>I would guess most people on this site are familiar with tail, if not - it provides a "follow" mode that as text is appended to the file tail will dump those characters out to the terminal.</p>
<p>What I am looking for (and possibly to write myself if necessary) is a version of tail that works on binary files. Basically I have a wireless link that I would like to trickle a file across as it comes down from another network link. Looking over the tail source code it wouldn't be too hard to rewrite, but I would rather not reinvent the wheel! This wouldn't strictly be "tail" as I would like the entire file to be copied, but it would watch as new bytes were added and stream those.</p>
<p>Ideas?</p>

232,237 | <p>What's the best way to return a random line in a text file using C? It has to use the standard I/O library (<code><stdio.h></code>) because it's for Nintendo DS homebrew.</p>
<p><strong>Clarifications:</strong></p>
<ul>
<li>Using a header in the file to store the number of lines won't work for what I want to do.</li>
<li>I want it to be as random as possible (the best being if each line has an equal probability of being chosen as every other line.)</li>
<li>The file will never change while the program is being run. (It's the DS, so no multi-tasking.)</li>

<p>I was able to make sure it was looping properly and it is.</p>
<p>The text = Hello
which is 16 1's, here is my proc for looping through that text to count the number of ones in it.</p>

</code></pre>
<p>the rest of the proc is just push/pops. What im wanting this to actually do is use TEST to compare 100000000 to a byte, if its a 1 inc AX else shift right the mask by 1 and loop a whole byte, than inc to next byte and do again.</p>

232,347 | <p>Many programs include an auto-updater, where the program occasionally looks online for updates, and then downloads and applies any updates that are found. Program bugs are fixed, supporting files are modified, and things are (usually) made better.</p>
<p>Unfortunately no matter how hard I look, I can't find information on this process anywhere. It seems like the auto-updaters that have been implemented have either been proprietary or not considered important.</p>
<p>It seems fairly easy to implement the system that looks for updates on a network and downloads them if they are available. That part of the auto-updater will change significantly from implementation to implementation. The question is what are the different approaches of <strong>applying</strong> patches. Just downloading files and replacing old ones with new ones, running a migration script that was downloaded, monkey patching parts of the system, etc.? Concepts are preferred, but examples in Java, C, Python, Ruby, Lisp, etc. would be appreciated.</p>

<p>How do I restrict the choices for Parent.favoritechild to only children whose parent is itself? I tried</p>
<pre><code>class Parent(models.Model):
name = models.CharField(max_length=255)
favoritechild = models.ForeignKey("Child", blank=True, null=True, limit_choices_to = {"myparent": "self"})

<p>but that causes the admin interface to not list any children.</p>

232,445 | <p>I'm just starting to learn C++ so excuse me for this simple question. What I'm doing is reading in numbers from a file and then trying to add them to an array. My problem is how do you increase the size of the array? For example I thought might be able to just do:</p>
<pre><code>#include <iostream>
using namespace std;
int main() {
double *x;
x = new double[1];
x[0]=5;
x = new double[1];
x[1]=6;
cout << x[0] << "," << x[1] << endl;
return 0;
}
</code></pre>
<p>But this obviously just overwrites the value, 5, that I initially set to x[0] and so outputs 0,6. How would I make it so that it would output 5,6?<br /><br />Please realize that for the example I've included I didn't want to clutter it up with the code reading from a file or code to get numbers from a user. In the actual application I won't know how big of an array I need at compile time so please don't tell me to just make an array with two elements and set them equal to 5 and 6 respectively.<br /><br />Thanks for your help.</p>

<p>I want to re-factor this code to use a DHTML modal pop-up window. The change should be as unobtrusive as possible.</p>
<p>To keep this solution at par with the old solution, I think would also need to do the following</p>
<ol>
<li>Provide a handle to "Close" the window.</li>
<li>Ensure the window cannot be moved, and is positioned at the center of the screen.</li>
<li>Blur the background as an option.</li>
</ol>
<p>I thought <a href="http://particletree.com/features/lightbox-gone-wild/" rel="nofollow noreferrer">this solution</a> is the closest to what I want, but I could not understand how to incorporate it.</p>
<p>Edit: A couple of you have given me a good lead. Thank you. But let me re-state my problem here. I am re-factoring existing code. I should avoid any change to the present HTML or CSS. Ideally I would like to achieve this effect by keeping the function signature of the genericPop(...) same as well.</p>

<p>I can't see, to track it down to a pattern or anything besides it is consistent.</p>
<p>For example if I call my program as "tail -24 test.in" I would get the the the incorrect checksum error at the same line on multiple runs. However, with different files and even different numbers of lines to print back I will come back without errors.</p>
<p>Any idea on how to track down the issue, I've been trying to debug it for hours to no avail.</p>
<p>Here is the offending code:</p>
<p>lines is defined as a char** and was malloc as:</p>
<pre><code>lines = (char**) malloc(nlines * sizeof(char *));
void insert_line(char *s, int len){
printf("\t\tLine Number: %d Putting a %d line into slot: %d\n",processed,len,slot);
if(processed > numlines -1){//clean up
free(*(lines+slot));
*(lines + slot) = NULL;
}
*(lines + slot) = (char *) malloc(len * sizeof(char));
if(*(lines + slot) == NULL) exit(EXIT_FAILURE);
strcpy(*(lines+slot),s);

232,681 | <p>I’ve almost 6 years of experience in application development using .net technologies. Over the years I have improved as a better OO programmer but when I see code written by other guys (especially the likes of Jeffrey Richter, Peter Golde, Ayende Rahien, Jeremy Miller etc), I feel there is a generation gap between mine and their designs. I usually design my classes on the fly with some help from tools like ReSharper for refactoring and code organization. </p>
<p>So, my question is “what does it takes to be a better OO programmer”. Is it </p>
<p>a) Experience</p>
<p>b) Books (reference please)</p>
<p>c) Process (tdd or uml) </p>
<p>d) patterns</p>
<p>e) anything else?</p>
<p>And how should one validate that the design is good, easy to understand and maintainable. As there are so many buzzwords in industry like dependency injection, IoC, MVC, MVP, etc where should one concentrate more in design. I feel abstraction is the key. What else?</p>

232,682 | <p>I've already written a generator that does the trick, but I'd like to know the best possible way to implement the off-side rule.</p>
<p>Shortly: <a href="http://en.wikipedia.org/wiki/Off-side_rule" rel="noreferrer">Off-side rule</a> means in this context that indentation is getting recognized as a syntactic element.</p>
<p>Here is the offside rule in pseudocode for making tokenizers that capture indentation in usable form, I don't want to limit answers by language:</p>
<pre><code>token NEWLINE
matches r"\n\ *"
increase line count
pick up and store the indentation level
remember to also record the current level of parenthesis
procedure layout tokens
level = stack of indentation levels
push 0 to level
last_newline = none
per each token
if it is NEWLINE put it to last_newline and get next token
if last_newline contains something
extract new_level and parenthesis_count from last_newline
- if newline was inside parentheses, do nothing
- if new_level > level.top
push new_level to level
emit last_newline as INDENT token and clear last_newline
- if new_level == level.top
emit last_newline and clear last_newline
- otherwise
while new_level < level.top
pop from level
if new_level > level.top
freak out, indentation is broken.
emit last_newline as DEDENT token
clear last_newline
emit token
while level.top != 0
emit token as DEDENT token
pop from level
comments are ignored before they are getting into the layouter
layouter lies between a lexer and a parser
</code></pre>
<p>This layouter doesn't generate more than one NEWLINE at time, and doesn't generate NEWLINE when there's indentation coming up. Therefore parsing rules remain quite simple. It's pretty good I think but inform if there's better way of accomplishing it.</p>
<p>While using this for a while, I've noticed that after DEDENTs it may be nice to emit newline anyway, this way you can separate the expressions with NEWLINE while keeping the INDENT DEDENT as a trailer for expression.</p>

232,691 | <p>I've allocated an "array" of <code>mystruct</code> of size <code>n</code> like this:</p>
<pre><code>if (NULL == (p = calloc(sizeof(struct mystruct) * n,1))) {
/* handle error */
}
</code></pre>
<p>Later on, I only have access to <code>p</code>, and no longer have <code>n</code>. Is there a way to determine the length of the array given just the pointer <code>p</code>?</p>
<p>I figure it <em>must</em> be possible, since <code>free(p)</code> does just that. I know <code>malloc()</code> keeps track of how much memory it has allocated, and that's why it knows the length; perhaps there is a way to query for this information? Something like...</p>
<pre><code>int length = askMallocLibraryHowMuchMemoryWasAlloced(p) / sizeof(mystruct)
</code></pre>
<p>I know I should just rework the code so that I know <code>n</code>, but I'd rather not if possible. Any ideas?</p>

232,747 | <p>I'm trying to read variables from a batch file for later use in the batch script, which is a Java launcher. I'd ideally like to have the same format for the settings file on all platforms (Unix, Windows), and also be a valid Java Properties file. That is, it should look like this:</p>
<pre><code>setting1=Value1
setting2=Value2
...
</code></pre>
<p>Is it possible to read such values like you would in a Unix shell script? The could should look something like this:</p>
<pre><code>READ settingsfile.xy
java -Dsetting1=%setting1% ...
</code></pre>
<p>I know that this is probably possible with <code>SET setting1=Value1</code>, but I'd really rather have the same file format for the settings on all platforms.</p>
<p>To clarify: I need to do this in the command line/batch environment as I also need to set parameters that cannot be altered from within the JVM, like -Xmx or -classpath.</p>

232,895 | <p>I came across an interesting article which shows how we can transparently encrypt jdbc connections using java thin client. </p>
<p><a href="http://javasight.wordpress.com/2008/08/29/network-data-encryption-and-integrity-for-thin-jdbc-clients/" rel="nofollow noreferrer">http://javasight.wordpress.com/2008/08/29/network-data-encryption-and-integrity-for-thin-jdbc-clients/</a></p>
<p>However I want to know how this can be achieved for application servers (like oc4j) datasources.</p>

232,905 | <p>I got this logic in a control to create a correct url for an image. My control basically needs to diplay an image, but the src is actually a complex string based on different parameters pointing at an image-server.</p>
<p>So we decided to to create a control MyImage derived from asp:Image - it works like a charm. Now i need the same logic but my image now needs to respond to a click. What i mean is - the 'MyImage' is used to display images on the site but in a few rare cases i would like it to be clickable.</p>
<p>I think i got three choices.</p>
<ol>
<li>Change MyImage to derive from asp:ImageButton instead of asp:Image.</li>
<li>Copy all the code from MyImage into a new MyClickImage and derive from asp:ImageButton.</li>
<li>Wrap logic on MyImage to add a hyperlink, implement IPostbackHandler for that hyperlink and add the logic to handle the event.</li>
</ol>
<p>Obviously i would very much like to avoid using option 2) since i would have to maintain two almost identically controls. The problem with option 1) <em>as i see it</em> (perhaps i'm wrong?) Is that all the images on the site that are not supposed to be clickable will automaticly become clickable. Option 3) seems overly complicated as i would have to maintain state, events and building the link manually.</p>
<p>I'm looking for a quick answer like 'you're stupid, just set property 'x' to false when you don't want it to be clickable' - but if i'm not mistaking it is not that obvious and ofcourse a more elaborate answer would be fine :)</p>
<p>EDIT: Added the 3rd option - i forgot to put that there in the first place :)</p>

232,926 | <p>For instance, winsock libs works great across all versions of the visual studio. But I am having real trouble to provide a consistent binary across all the versions. The dll compiled with VS 2005 won't work when linked to an application written in 2008. I upgraded both 2k5 and 2k8 to SP1, but the results haven't changed much. It works some what ok. But when they include this with a C# app, the C# app gets access violation errors, but with classic C++ application it works fine.</p>
<p>Is there a strategy that I should know when I provide dlls ?</p>

232,933 | <p>How do I multiply the values of a multi-dimensional array with weights and sum up the results into a new array in PHP or in general?</p>
<p>The boring way looks like this:</p>
<pre><code>$weights = array(0.25, 0.4, 0.2, 0.15);
$values = array
(
array(5,10,15),
array(20,25,30),
array(35,40,45),
array(50,55,60)
);
$result = array();
for($i = 0; $i < count($values[0]); ++$i) {
$result[$i] = 0;
foreach($weights as $index => $thisWeight)
$result[$i] += $thisWeight * $values[$index][$i];
}
</code></pre>
<p>Is there a more elegant solution?</p>

232,934 | <p>I want to subclass the built-in DropDownList in ASP.NET so that I can add functionality to it and use it in my pages. I tried doing this with a UserControl but found that it doesn't expose the internal DropDownList (logically, I guess). I've googled for the answer but can't find anything. </p>
<p>I've come as far as writing the actual class, and it's possible to subclass from DropDownList but I'm unable to register the file in my ASP.NET page and use it in the source view. Maybe I'm missing some properties in my class?</p>
<p>Any ideas?</p>

232,938 | <p>I have a .rc file which is used to include some text data in my executable, like this:</p>
<pre><code>1234 RCDATA myfile.txt
</code></pre>
<p>This works fine: the content of the 'myfile.txt' is included in my executable.
The problem is that no 0-terminator is added to the string, and I cannot add it to the file. Is there any way of adding a 0-terminator from within the .rc file? Something like this:</p>
<pre><code>1234 RCDATA { myfile.txt, "\0" } // error RC2104
</code></pre>
<p>Note that I already found this solution, but I am looking for something more elegant.</p>
<pre><code>1234 RCDATA myfile.txt
1235 RCDATA { "\0" }

<p>I have omitted the closing of the document for clarity and to keep this post short.</p>
<p>Anyway, I have a GridView and I want to bind this XML to the GridView so I get table, like:</p>
<pre><code>email | type | long | created | user
------------------------------------
data data data data data
</code></pre>
<p>And so forth.</p>
<p>I was playing with DataSets and XMLDataDocuments and when stepping through, each attribute seemed to be represented as its own table in a data collection table.</p>
<p>Any ideas on how to achieve the above? I thought it was as simple as just adding a GridView, and XML data source with the data file specified.</p>

232,986 | <p>I am attempting to bind a WPF textbox's Maxlength property to a known constant deep within a class. I am using c#.</p>
<p>The class has a structure not too dissimilar to the following:</p>
<pre><code>namespace Blah
{
public partial class One
{
public partial class Two
{
public string MyBindingValue { get; set; }
public static class MetaData
{
public static class Sizes
{
public const int Length1 = 10;
public const int Length2 = 20;
}
}
}
}
}
</code></pre>
<p>Yes it is deeply nested, but unfortunately in this instance I can't move things round very much without huge rewrites required.</p>
<p>I was hoping I'd be able to bind the textbox MaxLength to the Length1 or Length2 values but I can't get it to work.</p>
<p>I was expecting the binding to be something like the following:</p>
<pre><code><Textbox Text="{Binding Path=MyBindingValue}" MaxLength="{Binding Path=Blah.One.Two.MetaData.Sizes.Length1}" />
</code></pre>
<p>Any help is appreciated.</p>
<p>Many thanks</p>

232,997 | <p>I have what is essentially a jagged array of name value pairs - i need to generate a set of unique name values from this. the jagged array is approx 86,000 x 11 values.
It does not matter to me what way I have to store a name value pair (a single string "name=value" or a specialised class for example KeyValuePair).<br>
<strong>Additional Info:</strong> There are 40 distinct names and a larger number of distinct values - probably in the region 10,000 values.</p>
<p>I am using C# and .NET 2.0 (and the performance is so poor I am thinking that it may be better to push my entire jagged array into a sql database and do a select distinct from there).</p>
<p>Below is the current code Im using:</p>
<pre><code>List<List<KeyValuePair<string,string>>> vehicleList = retriever.GetVehicles();
this.statsLabel.Text = "Unique Vehicles: " + vehicleList.Count;
Dictionary<KeyValuePair<string, string>, int> uniqueProperties = new Dictionary<KeyValuePair<string, string>, int>();
foreach (List<KeyValuePair<string, string>> vehicle in vehicleList)
{
foreach (KeyValuePair<string, string> property in vehicle)
{
if (!uniqueProperties.ContainsKey(property))
{
uniqueProperties.Add(property, 0);
}
}
}
this.statsLabel.Text += "\rUnique Properties: " + uniqueProperties.Count;

233,013 | <p>I recently started learning Python and I was rather surprised to find a 1000 deep recursion limit (by default). If you set it high enough, about 30000, it crashes with a segmentation fault just like C. Although, C seems to go quite a lot higher.</p>
<p>(The Python folks are quick to point out that you can always convert recursive functions to iterative ones and that they're always faster. That's 100% true. It's not really what my question is about though.)</p>
<p>I tried the same experiment in Perl and somewhere around 10 million recursions it consumed all of my 4 gigs of ram and I used ^C to stop trying. Clearly Perl doesn't use the C stack, but it does use a ridiculous amount of memory when it recurses -- not terribly shocking considering how much work it has to do to call functions.</p>
<p>I tried in Pike and was completely surprised to get 100,000,000 recursions in about 2 seconds. I have no idea how it did that, but I suspect it flattened the recursion to an iterative process -- it doesn't seem to consume any extra memory while it does it. [Note: Pike does flatten trivial cases, but segfaults on more complicated ones, or so I'm told.]</p>
<p>I used these otherwise useless functions:</p>
<pre><code>int f(int i, int l) { if(i<l) return f(i+1,l); return i; }
sub f { return f($_[0]+1, $_[1]) if $_[0]<$_[1]; return $_[0] };
def f(i,l):
if i<l:
return f(i+1,l)
return i
</code></pre>
<p>I'm very curious how other languages (e.g., PHP, Ruby, Java, Lua, Ocaml, Haskell) handle recursion and why they handle it that way. Additionally, please note whether it makes a difference if the function is "tail-recursive" (see comment).</p>

233,088 | <p>The fundamental equation of weight loss/gain is:</p>
<pre><code>weight_change = convert_to_weight_diff(calories_consumed - calories_burnt);
</code></pre>
<p>I'm going on a health kick, and like a good nerd I thought I'd start keeping track of these things and write some software to process my data. I'm not attentive and disciplined enough to count calories in food, so I thought I'd work backwards:</p>
<ul>
<li>I can weigh myself every day</li>
<li>I can calculate my BMR and hence how many calories I burn doing nothing all day</li>
<li>I can use my heart-rate monitor to figure out how many calories I burn doing exercise</li>
</ul>
<p>That way I can generate an approximate "calories consumed" graph based on my exercise and weight records, and use that to motivate myself when I'm tempted to have a donut.</p>
<p>The thing I'm stuck on is the function:</p>
<pre><code>int convert_to_weight_diff(int calorie_diff);
</code></pre>
<p>Anybody know the pseudo-code for that function? If you've got some details, make sure you specify if we're talking calories, Calories, kilojoules, pounds, kilograms, etc.</p>
<p>Thanks! </p>

233,113 | <p>How do I get the type of a generic typed class within the class?</p>
<p>An example:</p>
<p>I build a generic typed collection implementing <em>ICollection< T></em>. Within I have methods like </p>
<pre><code> public void Add(T item){
...
}
public void Add(IEnumerable<T> enumItems){
...
}
</code></pre>
<p>How can I ask within the method for the given type <em>T</em>?</p>
<p>The reason for my question is: If <em>object</em> is used as <em>T</em> the collection uses Add(object item) instead of Add(IEnumerable<object> enumItems) even if the parameter is IEnumerable. So in the first case it would add the whole enumerable collection as one object instead of multiple objects of the enumerable collection.</p>
<p>So i need something like </p>
<pre><code>if (T is object) {
// Check for IEnumerable
}
</code></pre>
<p>but of course that cannot work in C#. Suggestions?</p>
<p>Thank you very much!</p>

233,127 | <p>We have a function which a single thread calls into (we name this the main thread). Within the body of the function we spawn multiple worker threads to do CPU intensive work, wait for all threads to finish, then return the result on the main thread.</p>
<p>The result is that the caller can use the function naively, and internally it'll make use of multiple cores.</p>
<p><em>All good so far..</em></p>
<p>The problem we have is dealing with exceptions. We don't want exceptions on the worker threads to crash the application. We want the caller to the function to be able to catch them on the main thread. We must catch exceptions on the worker threads and propagate them across to the main thread to have them continue unwinding from there.</p>
<p><strong><em>How can we do this?</em></strong></p>
<p>The best I can think of is:</p>
<ol>
<li>Catch a whole variety of exceptions on our worker threads (std::exception and a few of our own ones).</li>
<li>Record the type and message of the exception.</li>
<li>Have a corresponding switch statement on the main thread which rethrows exceptions of whatever type was recorded on the worker thread.</li>
</ol>
<p>This has the obvious disadvantage of only supporting a limited set of exception types, and would need modification whenever new exception types were added.</p>
