209,086 | <p>I've got a C++ Win32 application that has a number of threads that might be busy doing IO (HTTP calls, etc) when the user wants to shutdown the application. Currently, I play nicely and wait for all the threads to end before returning from <code>main</code>. Sometimes, this takes longer than I would like and indeed, it seems kind of pointless to make the user wait when I could just exit. However, if I just go ahead and return from <code>main</code>, I'm likely to get crashes as destructors start getting called while there are still threads using the objects.</p>
<p>So, recognizing that in an ideal, platonic world of virtue, the best thing to do would be to wait for all the threads to exit and then shutdown cleanly, what is the next best real world solution? Simply making the threads exit faster may not be an option. The goal is to get the process dead as quickly as possible so that, for example, a new version can be installed over it. The only disk IO I'm doing is in a transactional db, so I'm not terribly concerned about pulling the plug on that.</p>

209,127 | <p>I'm looking for a plugin for jQuery that can validate as a key is pressed and after it loses focus (text boxes). </p>
<p>I'm currently using <a href="http://www.overset.com/2008/07/31/jval-jquery-form-field-validation-plugin/" rel="nofollow noreferrer">jVal - jQuery Form Field Validation Plugin</a>. It works pretty good. The only issue I have is that I can only use a generic error message.</p>
<p>For example:
I need a string to between 2 and 5 characters. If its too short I would like to display an error message that indicates it to short, equally if its too long. I know I could display an error message that requires the string to between 2 and 5 characters. <strong>The validation that is being done is more complicated.</strong> </p>
<p>Any ideas of other validators or how I could use this plug-in to display unique error messages.</p>
<hr>
<p>Edit:</p>
<p>The validation tool needs to prevent particular letters or numbers and not require a form. </p>
<p>Thanks</p>

209,135 | <p>When working on some code, I add extra debug logging of some kind to make it easier for me to trace the state and values that I care about for this particular fix.</p>
<p>But if I would check this in into the source code repository, my colleagues would get angry on me for polluting the Log output and polluting the code.</p>
<p>So how do I locally keep these lines of code that are important to me, without checking them in?</p>
<p><strong>Clarification:</strong>
Many answers related to the log output, and that you with log levels can filter that out. And I agree with that.</p>
<p>But. I also mentioned the problem of polluting the actual code. If someone puts a log statement between every other line of code, to print the value of all variables all the time. It really makes the code hard to read. So I would really like to avoid that as well. Basically by not checking in the logging code at all. So the question is: how to keep your own special purpose log lines. So you can use them for your debug builds, without cluttering up the checked in code.</p>

209,145 | <p>When setting the export path in Unix, example:</p>
<pre><code>export PATH=$PATH: $EC2_HOME/bin
</code></pre>
<p>If I quit terminal and open it back up to continue working, I have to go through all the steps again, setting up the paths each time.
I'm wondering how I can set the path and have it "stick" so my system knows where to find everything the next time I open terminal without having to do it all over again.
Thanks!</p>

209,160 | <p>I want to do something like this :</p>
<pre><code>myYear = record.GetValueOrNull<int?>("myYear"),
</code></pre>
<p>Notice the nullable type as the generic parameter. </p>
<p>Since the <code>GetValueOrNull</code> function could return null my first attempt was this: </p>
<pre><code>public static T GetValueOrNull<T>(this DbDataRecord reader, string columnName)
where T : class
{
object columnValue = reader[columnName];
if (!(columnValue is DBNull))
{
return (T)columnValue;
}
return null;
}
</code></pre>
<p>But the error I'm getting now is:</p>
<blockquote>
<p>The type 'int?' must be a reference type in order to use it as parameter 'T' in the generic type or method</p>
</blockquote>
<p>Right! <code>Nullable<int></code> is a <code>struct</code>! So I tried changing the class constraint to a <code>struct</code> constraint (and as a side effect can't return <code>null</code> any more):</p>
<pre><code>public static T GetValueOrNull<T>(this DbDataRecord reader, string columnName)
where T : struct
</code></pre>
<p>Now the assignment:</p>
<pre><code>myYear = record.GetValueOrNull<int?>("myYear");
</code></pre>
<p>Gives the following error:</p>
<blockquote>
<p>The type 'int?' must be a non-nullable value type in order to use it as parameter 'T' in the generic type or method</p>
</blockquote>
<p>Is specifying a nullable type as a generic parameter at all possible?</p>

209,192 | <p>I would like to match the time (10.00) from a string with the date and time ("21.01.08 10.00"). I'm using the following regular expression:</p>
<pre><code>new RegExp("\\b[0-9]{1,2}\\.[0-9]{1,2}\\b" "g");
</code></pre>
<p>But this matches 21.01 from 21.01.08 and 10.00.</p>
<p>I'm using PCRE as my regualar expression engine. </p>
<p>Update:</p>
<p>I'm sorry, i should have more been more clear. The data and time are part of a larger string. I want to extract the time from that string.</p>
<p>For example:</p>
<p>"On 21.01.08 from 10.00 a party will take place in the library"
"21.08.08 - At 10:00 there will be a party"
"On 21.08.08 you are scheduled for a ... . The ... will begin at 10.00"</p>
<p>Is this possible?</p>

209,198 | <p>I am using Borland Turbo C++ with some inlined assembler code, so presumably Turbo Assembler (TASM) style assembly code. I wish to do the following:</p>
<pre><code>void foo::bar( void )
{
__asm
{
mov eax, SomeLabel
// ...
}
// ...
SomeLabel:
// ...
}
</code></pre>
<p>So the address of SomeLabel is placed into EAX. This doesn't work and the compiler complains of: Undefined symbol 'SomeLabel'.</p>
<p>In Microsoft Assembler (MASM) the dollar symbol ($) serves as the current location counter, which would be useful for my purpose. But again this does not seem to work in Borlands Assember (expression syntax error).</p>
<p>Update: To be a little more specific, I need the compiler to generate the address it moves into eax as a constant during compilation/linking and not at run time, so it will compile like "mov eax, 0x00401234".</p>
<p>Can anybody suggest how to get this working?</p>
<p>UPDATE: To respond to Pax's question (see comment), If the base address is changed at run time by the Windows loader the DLL/EXE PE image will still be relocated by the Windows loader and the labels address will be patched at run time by the loader to use the re-based address so using a compile/link time value for the label address is not an issue.</p>
<p>Many thanks in advance.</p>

209,224 | <p>I have to consume 2 different web services. Both contain a definition for a 'user' object. </p>
<p>When I reference the services using "Add service reference" I give each service a unique namespace:</p>
<pre><code>com.xyz.appname.ui.usbo.UserManagement
com.xyz.appname.ui.usbo.AgencyManagement
</code></pre>
<p>The problem I have is that each one of the proxies that are generated contain a new user class. One is located at com.xyz.appname.ui.usbo.UserManagement.user and the other at com.xyz.appname.ui.usbo.AgencyManagement.user. However, the user objects are identical and I would like to treat them as such.</p>
<p>Is there a way that I can somehow reference the user object as one object instead of treating them as two different?</p>
<p>I am using .Net 3.5 to consume the service. The service being consumed is written in Java.</p>
<p>Thanks!!</p>

209,255 | <p>I've got a unidirectional tree of objects, in which each objects points to its parent. Given an object, I need to obtain its entire subtree of descendants, as a collection of objects. The objects are not actually in any data structure, but I can easily get a collection of all the objects.</p>
<p>The naive approach is to examine each object in the batch, see if the given object is an ancestor, and keep it aside. This would not be too efficient... It carries an overhead of O(N*N), where N is the number of objects.</p>
<p>Another approach is the recursive one, meaning search for the object's direct children and repeat the process for the next level. Unfortunately the tree is unidirectional... there's no direct approach to the children, and this would be only slightly less costly than the previous approach.</p>
<p>My question: Is there an efficient algorithm I'm overlooking here?</p>

<p>This is the code on my server app:</p>
<pre><code>TcpChannel tcpChannel = new TcpChannel(999);
MyRemoteObject remObj = new MyRemoteObject (this);
RemotingServices.Marshal(remObj, "MyUri");
ChannelServices.RegisterChannel(tcpChannel);
</code></pre>
<p>It seems to work the first time, but unless the server app is restarted the error occurs.</p>
<p>I would guess something isn't being cleaned up properly but I'm not sure what as the customError is still on.</p>
<p>Any ideas where I start. Thanks.</p>
<p>[EDIT] - Thanks to Gulzar, I modified my code above to the following and now the errors are shown:</p>
<pre><code>RemotingConfiguration.CustomErrorsMode = CustomErrorsModes.Off;
TcpChannel tcpChannel = new TcpChannel(999);
MyRemoteObject remObj = new MyRemoteObject (this);
RemotingServices.Marshal(remObj, "MyUri");
ChannelServices.RegisterChannel(tcpChannel);
</code></pre>

209,258 | <p>I am trying to use a third party DLL that wants an int** as one of the parameters to the method. It describes the parameter as the address of the pointer that will point to the memory allocation.</p>
<p>Sorry for any confusion. The parameter is two-way I think. The DLL is for talking to an FPGA board and the method is setting up DMA transfer between the host PC and the PCI board.</p>

209,301 | <p>How do I post a form from an HTML page to and ASPX page (2.0) and be able to read the values?</p>
<p>I currently have an ASP.NET site using the Membership provider and everything is working fine. Users can log in from the Login.aspx page.</p>
<p>We now want to be able to have users log in directly from another web site--which is basically a static HTML page. The users need to be able to enter their name and password on this HTML page and have it POST to my Login.aspx page (where I can then log them in manually).</p>
<p>Is it possible to pass form values from HTML to ASPX? I have tried everything and the Request.Form.Keys collection is always empty. I can't use a HTTP GET as these are credentials and can't be passed on a query string.</p>
<p>The only way I know of is an iframe.</p>

209,305 | <p>I'm writing a C/C++ application under Linux that reads data from a raw socket (for ICMP packets). Question: is there a way to discard all data that is still queued on the socket?</p>
<p>The problem is that after sleeping for a while, there is data queued up on the socket which I'm not interested in; so it would be best to just tell the socket "forget all data you have buffered right now", so that if I go into a select()/recvfrom() loop then, I only get data that was received recently.</p>
<p>Is there a better way than going into a separate poll()/recvfrom() loop first? Some socket API call maybe? Portable, even? :-)</p>

209,320 | <p>I have an activex object I loaded into an html page. I then use that activex object to create another object, but I need to register an event with the new object created. The object is expecting an event listener of a certain type.</p>
<p>I can load this same dll in c# and it will work fine. Code looks like this for c#.</p>
<pre><code>upload = obj.constructUploadObj(uploadConfig);
upload.stateChanged += new UploadActionEvents_stateChangedEventHandler(upload_stateChanged);
</code></pre>
<p>In javascript I have similar code however I cannot get the event registered with the object.</p>
<pre><code>uploadAction = obj.constructUploadObj(uploadConfig);
uploadAction.stateChanged = upload_stateChanged;
function upload_stateChanged(sender){
writeLine("uploadState changed " + sender.getState());
}
</code></pre>
<p>I have enumerated some of the properties of the uploadAction object in javascript to ensure that it is actually created. When I try and register the event with uploadAction it throws an error saying "Object doesn't support this property or method."</p>
<p>To me it seems like its expecting a strongly typed event. Is there anyway to register the event similar to that of C# in javascript?</p>
<p>Thanks In Advance.</p>

<p>But what do I do with chinese, japanese, arabian letters that has nothing to do with our western ASCII format? </p>
<p>I really don't like the idea of rewriting the URL with hex codes, so right now I just use my internal unique ID if the url contains too many "non convertable" characters.</p>

209,354 | <p>I am currently developing an approval routing WCF service that will allow an user to create "rules" which determine how an request is routed. The route is determined by comparing the "ObjectToEvaluate" property of the Request class against the "ObjectToEvaluate" property of the "Rule" class. The "UnitOfMeasurement" enum determines how to cast the "ObjectToEvaluate" property for each class. </p>
<pre><code>public enum UnitOfMeasurement

Currency = 1,
Numeric = 2,
Special = 3,
Text = 4,

public class Request

public object ObjectToEvaluate { get; set; }
public virtual void ExecuteRule()
{
//logic to see if it passes the rule condition

<p>What would be the best way to implement the method to cast the "ObjectToEvaluate" property using the "UnitOfMeasurement" enum?</p>

209,376 | <p>Is it possible to use SQL Server 2008 CROSS APPLY with LINQ-2-SQL? </p>

<pre><code>select d.dateCol, tvf.descr, tvf.value
from dateTable d
cross apply tvFunction(d.dt, 'anotherParam') tvf
where d.category='someCat'
</code></pre>
<p>CROSS APPLY enables using values from a table (dateTable in the example) as parameters to a tablevalue function. This is very usefull if you need do do a complex calculation (encapsulated in a table value function) for a range of inputs.</p>

209,407 | <p>I am developing a specialty application where the end-user needs to operate multiple controls simultaneously. The application is used to "tune" the control parameters of an electronic device to calibrate the unit to its best performance.</p>
<p>Currently, there is a UI with multiple graphical sliders which the operator click-drags one slider at a time. He can also click on a slider, and use the mouse-scroll wheel, which is a little easier to use.</p>
<p>This works, sort of, but is somewhat cumbersome. The various parameters (5 in this particular case) are sufficiently independent of each other so that I can't just refactor the parameters into a single adjustment. And, if the operator can keep his eye on the device being adjusted, rather than the UI of the control application, it would speed up and simplify his work.</p>
<p>One idea that I had was that I might buy a whole bunch of the USB jog-dial products, and bind each dial to a specific control. This way, the operator can quickly adjust any parameter, or even two parameters simultaneously. (BTW, Griffin PowerMate comes to immediate mind, but I know there are a few other jog dials out there.)</p>
<p>Do you have any suggestions?</p>
<p>ADDED:</p>
<p>Keep in mind that in some cases, the parameters are adjusted in different directions, and may be significantly different in the adjustment steps. It's not a simple "track two channels together, and then fine tune the last bit of difference".</p>

<p>I haven't used events much in C#, but the fact that this would cause a NullRefEx seems weird. The EventHandler reference is considered null because it currently has no subsribers - but that doesn't mean that the event hasn't occurred, does it?</p>
<p>EventHandlers are differentiated from standard delegates by the <strong>event</strong> keyword. Why didn't the language designers set them up to fire silently in to the void when they have no subscribers? (I gather you can do this manually by explicitly adding an empty delegate).</p>

209,428 | <p>HTML (or maybe just XHTML?) is relatively strict when it comes to non-standard attributes on tags. If they aren't part of the spec, then your code is considered non-compliant.</p>
<p>Non-standard attributes can be fairly useful for passing along meta-data to Javascript however. For instance, if a link is suppose to show a popup, you can set the name of the popup in an attribute:</p>
<pre><code><a href="#null" class="popup" title="See the Popup!"
popup_title="Title for My Popup">click me</a>
</code></pre>
<p>Alternatively, you can store the title for the popup in a hidden element, like a span:</p>
<pre><code><style>
.popup .title { display: none; }
</style>
<a href="#null" title="See the Popup!" class="popup">
click me
<span class="title">Title for My Popup</span>
</a>
</code></pre>
<p>I am torn however as to which should be a preferred method. The first method is more concise and, I'm guessing, doesn't screw with search engines and screen readers as much. Conversely, the second option makes storing large amounts of data easier and is thus, more versatile. It is also standards compliant.</p>
<p>I am curious what this communities thoughts are. How do you handle a situation like this? Does the simplicity of the first method outweigh the potential downsides (if there are any)?</p>

209,465 | <p>I could use some help trying to track down an intermittent error that I've been having with our ASP.Net project for quite some time.</p>
<p>Intermittently when building the solution, the build will fail with the error "/: Build (web): Object reference not set to an instance of an object." The error has no associated file, line, column or project information. The weird thing about the error is that it will go away on successive rebuilds and doesn't seem to result in any run-time errors that we've come across once the build is successful. Sometimes the error will pop only once, sometimes 3-4 times, but eventually the build will finish successfully and then seems to build just fine each time after. I haven't been able to nail down a pattern as to why and when the error will happen, and since it always eventually builds it hasn't been a critical problem for us. Just an annoyance. But one that I want gone for obvious reasons.</p>
<p>I guess I should add that this is an application that was originally developed in ASP.net 1.1 and converted to 2.0 and I inherited it somewhere down the line after that, so I don't know when the problem originally surfaced. As far as everyone here is concerned, it's always been there.</p>
<p>Obviously I'm not expecting someone to pick out the cause of my problem as that would require them to look at our entire solution to pick out potential problems. Just hoping someone can give me a couple fresh ideas as to how to go about tracking down the actual source of the error in code. It has to be coming from somewhere, right? How would you go about finding out where?</p>

209,478 | <p>Hopefully I haven't misunderstood the meaning of "duck typing", but from what I've read, it means that I should write code based on how an object responds to methods rather than what type/class it is.</p>
<p>Here's the code:</p>
<pre><code>def convert_hash(hash)
if hash.keys.all? { |k| k.is_a?(Integer) }
return hash
elsif hash.keys.all? { |k| k.is_a?(Property) }
new_hash = {}
hash.each_pair {|k,v| new_hash[k.id] = v}
return new_hash
else
raise "Custom attribute keys should be ID's or Property objects"
end
end
</code></pre>
<p>What I want is to make sure that I end up with a hash where the keys are an integer representing the ID of an ActiveRecord object. I don't particularly enjoy having to iterate through the hash keys twice with <code>all?</code> to determine if I need to grab the ID's out.</p>
<p>Of course, I'll accept any other suggestions to improve this code as well :)</p>

209,491 | <p>I have a form using multiple <code><cfinput type="datefield" ...></code>. They are positioned in such a way that the pop-up CSS calendar should appear over the field for others. However, the text fields for the other dates end up in front of the calendar.</p>
<p>This is only an IE issue as Firefox and Safari work just fine.</p>
<p>Is there a simple CSS hack or some other simple thing I can do to get the calendar to act as it should? Re-arranging the form is not very helpful.</p>

209,509 | <p>Instead of using the <code><input type="file"></code> tag I'd like to have a button that launches a file browser dialog.</p>
<p>My first thought was to have a hidden file input tag and a button. I'd use the button click on the button to fire the onclick of the hidden file input, but I haven't been able to get this working properly.</p>
<p>So the question is, is this even possible? And second is there a nicer way to do this and still be able to send the information back in a form?</p>
<p>This will be the bottom layer of degrading functionality (from Flash to JavaScript (our site doesn't work without JS)) so it has to work with just basic JS and HTML.</p>

209,516 | <p>I inherited this gigantic legacy Java web app using Struts 1.2.4. I have a specific question regarding Actions. Most of the pages have exactly one Action, and the processExecute() methods are hideous monsters (very long and tons of nested if statements based on request parameters).</p>
<p>Given that Actions are an implementation of the command pattern, I'm thinking to split these Actions into one Action per user gesture. This will be a large refactoring though, and I'm wondering:</p>
<ol>
<li>Is this the right direction?</li>
<li>Is there an intermediate step I could take, a pattern that deals with the mess inside the monolithic actions? Maybe another command pattern inside the Action?</li>

209,558 | <p>I'm attempting to put together some basic report screens. I've got some fairly complicated SQL queries that I'm feeding into ActiveRecord's find_by_sql method.

<p>I'm trying to figure out how to grab ANY of the "resource_value". The problem being that while this works for a number of other queries, I have one particular table that uses ntext datatypes instead of varchars (which can't utilize the MAX function). So basically, MAX doesn't work here. Is there a substitute I can use on MS SQL Server 2005?</p>
<p>I need the prodtree_element_name_l column grouped, but I only need one value from the resource_value column, and I don't care what it is as most of them are identical regardless (although some are not, hence I can't group that one as well).</p>

<p>Whoops, I was wrong, prodtree_element_name_l is ALSO an NTEXT. That might help a little :p</p>

209,686 | <p>I've often had to load multiple items to a particular record in the database. For example: a web page displays items to include for a single report, all of which are records in the database (Report is a record in the Report table, Items are records in Item table). A user is selecting items to include in a single report via a web app, and let's say they select 3 items and submit. The process will add these 3 items to this report by adding records to a table called ReportItems (ReportId,ItemId).</p>
<p>Currently, I would do something like this in in the code:</p>
<pre><code>public void AddItemsToReport(string connStr, int Id, List<int> itemList)
{
Database db = DatabaseFactory.CreateDatabase(connStr);
string sqlCommand = "AddItemsToReport"
DbCommand dbCommand = db.GetStoredProcCommand(sqlCommand);
string items = "";
foreach (int i in itemList)
items += string.Format("{0}~", i);
if (items.Length > 0)
items = items.Substring(0, items.Length - 1);
// Add parameters
db.AddInParameter(dbCommand, "ReportId", DbType.Int32, Id);
db.AddInParameter(dbCommand, "Items", DbType.String, perms);
db.ExecuteNonQuery(dbCommand);
}
</code></pre>
<p>and this in the Stored procedure:</p>
<pre><code>INSERT INTO ReportItem (ReportId,ItemId)
SELECT @ReportId,
Id
FROM fn_GetIntTableFromList(@Items,'~')
</code></pre>
<p>Where the function returns a one column table of integers.</p>
<p>My question is this: is there a better way to handle something like this? Note, I'm not asking about database normalizing or anything like that, my question relates specifically with the code.</p>

209,706 | <p>I'm asking in generalities - why would any server not set and return headers and/or status codes? I can't think of a good reason for this. Perhaps I'm overlooking something.</p>

209,721 | <p>I'm doing a personal organizer for learning purposes, and i've never worked with XML so i'm not sure if my solution is the best. Here's the basic structure for the XML file i came with:</p>
<pre><code><calendar>
<year value="2008">
<month value="october">
<day value="16">
<activity name="mike's birthday" time="21:00" address="mike's apartment" urgency="10">
activity description.
</activity>
</day>
</month>
</year>
</calendar>
</code></pre>
<p>The urgency attribute should be on a scale of 1 to 10. <br/>
I did a quick search on google and couldn't find a good example. Maybe that's not the best solution, and i'd like to know if its adequate. I'm doing the application in PHP if that has any relevance.</p>

209,725 | <p>We have an auto-complete list that's populated when an you send an email to someone, which is all well and good until the list gets really big you need to type more and more of an address to get to the one you want, which goes against the purpose of auto-complete</p>
<p>I was thinking that some logic should be added so that the auto-complete results should be sorted by some function of most recently contacted or most often contacted rather than just alphabetical order.</p>
<p>What I want to know is if there's any known good algorithms for this kind of search, or if anyone has any suggestions. </p>
<p>I was thinking just a point system thing, with something like same day is 5 points, last three days is 4 points, last week is 3 points, last month is 2 points and last 6 months is 1 point. Then for most often, 25+ is 5 points, 15+ is 4, 10+ is 3, 5+ is 2, 2+ is 1. No real logic other than those numbers "feel" about right.</p>
<p>Other than just arbitrarily picked numbers does anyone have any input? Other numbers also welcome if you can give a reason why you think they're better than mine</p>
<p>Edit: This would be primarily in a business environment where recentness (yay for making up words) is often just as important as frequency. Also, past a certain point there really isn't much difference between say someone you talked to 80 times vs say 30 times.</p>

209,731 | <p>First of all, using gnome is not an option (but it is possible to install its libraries).</p>
<p>I need to know what is necessary to display a Java Swing desktop application using the current installed KDE look and feel of KDE. Ideally, the solution should allow me to apply a look and feel that looks like the underlying windowing system (ie: Windows LNF for Windows, GTK LNF for Gnome(GTK), QT LNF for KDE (QT), the default one for other platforms).</p>
<p>Under KDE, you can configure it to use the current KDE theme for GTK applications, too. So, if the solution works with GTK it is fine.</p>
<p>When I run the following piece of code under Gnome (Ubuntu 8.04), the Java application looks beautiful. It integrates very well with the rest of applications:</p>
<pre><code>try {
// Set System L&F
UIManager.setLookAndFeel(
UIManager.getSystemLookAndFeelClassName());
} catch(Exception e) { //Handle it }
</code></pre>
<p>However, if I run the same thing under Debian (Lenny) with KDE, the UIManager.getSystemLookAndFeelClassName() call returns the Java default one.
If I go ahead and force it to use the GTK LNF, the application doesn't work. Some fields are invisible, others become out of place, everything is unusable:</p>
<pre><code>try {
//Force the GTK LNF on top of KDE, but **it doesn't work**
UIManager.setLookAndFeel("com.sun.java.swing.plaf.gtk.GTKLookAndFeel");
} catch (Exception e) { /*Handle it*/ }
</code></pre>
<p>I've also tried to put the following code. It let's the user chose any one of the available LNF and then tries to set it. Metal and Motif work fine. GTK doesn't. The slider is really messed up. The list box looks ugly and disappears, but seems to work. Buttons and menu seem ok. The relevant code is shown here:</p>
<pre><code>(...)
/** Creates new form SwingFrame */
public SwingFrame() {
initComponents();
//Save all available lafs in a combobox
cbLafs.removeAllItems();
UIManager.LookAndFeelInfo[] lafs=UIManager.getInstalledLookAndFeels();
for (int i=0,t=lafs.length;i<t;i++)
{
cbLafs.addItem(lafs[i]);
System.out.println(lafs[i].getName());
}
}
public void changeLookAndFeel(String laf)
{
//If not specified, get the default one
if (laf==null) {
laf=UIManager.getSystemLookAndFeelClassName();
}
try {
// Set System L&F
UIManager.setLookAndFeel(laf);
}
catch (Exception e) {
// handle exception
e.printStackTrace();
}
SwingUtilities.updateComponentTreeUI(this);
}
private void cbLafsActionPerformed(java.awt.event.ActionEvent evt) {
// TODO add your handling code here:
UIManager.LookAndFeelInfo laf=(UIManager.LookAndFeelInfo)cbLafs.getSelectedItem();
if (laf==null)
changeLookAndFeel(null);
else
changeLookAndFeel(laf.getClassName());
}
</code></pre>
<p>This same system has all GTK applications working (for example: Firefox) as expected. So:</p>
<p>1) What is missing from the environment to have a Java GTK LNF application working under KDE?</p>
<p>2) What does the JVM checks for to return GTK as the default system theme?</p>
<p>Thanks for you help
Luis Fernando</p>
<p>PS->I've tried other solutions,too, such as JGoodies, plain AWT and SWT. However, Swing with GTK LNF would be the best solution to avoid the hassle of SWT native libraries and JGoodies extra jars (also, JGoodies LNF doesn't look as integrated as Swing GTK under Gnome). AWT looks hideous (motif-like) and misses lots of features.</p>

209,732 | <p>I have code similar to this filtering entries in an Array of Objects:</p>

if (filterRegex.test(events[i].thing) && events[i].show) {
console.log("SUCCESS: filtering thing " + i + " " + events[i].thing);

<p>I get inconsistent results with this if condition (checking with Firebug, both conditions are true individually, but <em>sometimes</em> the whole expression evaluates to false). HOWEVER, if I actually put an <code>alert()</code> called inside this if statement (like line 4), it becomes consistent and I get the result I want.</p>
<p>Can you see anything wrong with this logic and tell me why it's not always producing what is expected?</p>

209,793 | <p>Kind of a random question...</p>
<p>What I'm looking for is a way to express a cast operation which uses a defined operator of the class instance I'm casting from, and generates a compile-time error if there is not a defined cast operator for the type. So, for example, what I'm looking for is something like:</p>
<pre><code>template< typename RESULT_TYPE, typename INPUT_TYPE >
RESULT_TYPE operator_cast( const INPUT_TYPE& tValue )
{
return tValue.operator RESULT_TYPE();
}
// Should work...
CString sString;
LPCTSTR pcszString = operator_cast< LPCTSTR >( sString );
// Should fail...
int iValue = 42;
DWORD dwValue = operator_cast< DWORD >( iValue );
</code></pre>
<p>Interesting side-note: The above code crashes the VS2005 C++ compiler, and doesn't compile correctly in the VS2008 C++ compiler due to what I'm guessing is a compiler bug, but hopefully demonstrates the idea.</p>
<p>Anybody know of any way to achieve this effect?</p>
<p>Edit: More rationale, to explain why you might use this. Say you have a wrapper class which is supposed to encapsulate or abstract a type, and you're casting it to the encapsulated type. You could use static_cast<>, but that might work when you wanted it to fail (ie: the compiler chooses an operator which is allowed to convert to the type you asked for, when you wanted a failure because that operator is not present).</p>
<p>Admittedly it's an uncommon case, but it's annoying that I can't express exactly what I want the compiler to do in an encapsulated function... hence the question here.</p>

209,795 | <p>All of this is pertaining to WebHttp binding, hosted in a custom Service Host (IIS is not an option at this time).</p>

<p>The class that contains this code is in the <strong>com.xyz</strong> package, if that makes any difference. That class also extends JFrame. This code is throwing a MalformedUrlException on the first line.</p>
<p>Anyone have a solution that works?</p>

209,820 | <p>I want to be able to introduce new 'tag lines' into a database that are shown 'randomly' to users. (These tag lines are shown as an introduction as animated text.)</p>
<p>Based upon the number of sales that result from those taglines I'd like the good ones to trickle to the top, but still show the others less frequently.</p>
<p>I could come up with a basic algorithm quite easily but I want something thats a little more 'statistically accurate'.</p>
<p>I dont really know where to start. Its been a while since I've done anything more than basic statistics. My model would need to be sensitive to tolerances, but obviously it doesnt need to be worthy of a PHD.</p>
<p><strong>Edit:</strong> I am currently tracking a 'conversion rate' - i.e. hits per order. This value would probably be best calculated as a cumulative 'all time' convertsion rate to be fed into the algorithm.</p>

209,869 | <p>Some of my data are 64-bit integers. I would like to send these to a JavaScript program running on a page.</p>
<p>However, as far as I can tell, integers in most JavaScript implementations are 32-bit signed quantities.</p>
<p>My two options seem to be:</p>
<ol>
<li>Send the values as strings</li>
<li>Send the values as 64-bit floating point numbers</li>
</ol>
<p>Option (1) isn't perfect, but option (2) seems far less perfect (loss of data).</p>
<p>How have you handled this situation?</p>

209,874 | <p>New to javascript/jquery and having a hard time with using <code>this</code> or <code>$(this)</code> to get the current object.</p>
<p>I have a table with a set of <code>radio buttons</code> on each row, each named <code>s_<rowindex></code>. None of the radio buttons are checked by default:</p>
<pre><code><tr>
<td align="left" style="width: 300px">
<div id="div_s_0">
<input type="radio" name="s_0" value="1" />Public

<input type="radio" name="s_1" value="2" />Not Public
<input type="radio" name="s_1" value="3" />Confidential
</div>
</td>
</tr>
</code></pre>
<p>I'm trying to write a jQuery function to add a new row to the table whenever the user selects a radio button, but only if they are currently on the last row of the table. What I'd like to do is get the name attribute of the clicked radio button, parse it to get the row index (i.e. the part after the '_') and compare it to the number of rows in the table. If they are equal, add a new row, otherwise, do nothing.</p>
<p>My question is twofold, depending on how I should attack this:</p>
<p>1) How do I return the name attribute of a radio button, OR
2) How do I return the row index of the row I am currently in?</p>

209,888 | <p>Python 3.0 is in beta with a final release coming shortly. Obviously it will take some significant time for general adoption and for it to eventually replace 2.x.</p>
<p>I am writing a tutorial about certain aspects of programming Python. I'm wondering if I should do it in Python 2.x or 3.0? (not that the difference is huge)</p>
<p>a 2.x tutorial is probably more useful now, but it would be nice to start producing 3.0 tutorials.</p>
<p>anyone have thoughts?</p>
<p>(of course I could do both, but I would prefer to do one or the other)</p>

209,890 | <p>I'm looking for a regex that can pull out quoted sections in a string, both single and double quotes.</p>
<p>IE:</p>
<pre><code>"This is 'an example', \"of an input string\""

<p>Matches:</p>
<ul>
<li>an example</li>
<li>of an input string</li>
</ul>
<p>I wrote up this:</p>
<pre><code> [\"|'][A-Za-z0-9\\W]+[\"|']
</code></pre>
<p>It works but does anyone see any flaws with it?</p>
<p>EDIT: The main issue I see is that it can't handle nested quotes.</p>

<p>to no avail. Only a disc appears. If I want each individual list item to have it's own bullet, how can I accomplish this with css, <strong><em>without using background images</em></strong>.</p>
<p>Edit : I have discovered that, despite what firebug tells me, the list-style-image rule is being overridden somehow. If I inline the rule, like so:</p>

<p>then all is well. Since I have no other rules in the test case I'm running that contains ul or li in the selector, I'm not sure why inlining gives a different result.</p>

210,022 | <p>I have a requirement on my current project (a Flex app which will be run in Flash player) to display an arbitrary subset of the components on a form while hiding all the other components based on certain aspects of the application state. There are about a dozen different text boxes and drop downs, but some become irrelevant based on previously entered user data and we don't want to display those when we get to this particular form. Every time this form is displayed I could need to show any one of the many permutations of these components.</p>
<p>I'm trying to decide what the best way to approach this problem is. Should I create a Canvas (or other container) with all of the needed controls on it and then just set visible = false on the ones I don't need? The problem then becomes making sure the layout looks decent. I don't want there to be gaps where the hidden controls would have been.</p>
<p>The other option I've thought about is just having a mechanism that could dynamically instantiate the TextInput or CheckBox etc. component and then call container.addChild(control) in order to build up the components and not have to worry about the gap issue.</p>
<p>This seems like a problem that has an idiomatic solution in flex, but I don't know what it is. Neither of these ideas seem great so I'm wondering if anyone else has a better idea.</p>

<pre><code>test=
</code></pre>
<p>I've tried the following regex</p>
<pre><code>(\S+)=(\S.*)
(\S+)?=
[^=]{1}
...
</code></pre>
<p>Thanks all.</p>

210,088 | <p>I have a website that is deployed between 3 different environments - Dev, Stage, and Prod. For Stage and Prod, the site can resolve local paths to images with just the base url to the file, such as /SiteImages/banner.png. However, on the Dev server I have to hard code the full URL of the image path for the image to be resolved, such as <a href="http://server/folder/SiteImages/banner.png" rel="nofollow noreferrer">http://server/folder/SiteImages/banner.png</a>. Is there a setting I can flip to make the Dev server behave in the same manner as the other 2? I am using IIS 6.0 on a Win 2003 server. </p>

210,094 | <p>There is a store procedure that uses FREETEXTTABLE twice on two tables and then merges the results and returns the top 50. </p>
<p>The problem is if I do a search on "Women of Brewster", the results returns "Confession of an ex doofus motha" with a rank of 143 from table A and second "Women of Brewster Place" with a rank of 102 from table B.</p>
<p>Is this because of the count? (Table A return results total is 2399. Table B return results total is 3445.)</p>
