352,474 | <p>I have an interface A, for which I have to supply a few different
implementations. However, those implementations share some helper methods, so
I moved those methods to an abstract base class.</p>
<pre><code>Interface A {
void doX();
}
abstract Class B implements A {
protected void commonY() {
// ...
}
@Override
public abstract void doX();
}
Class C extends B {
@Override
public void doX() {
// ...
}
}
Class D extends B {
@Override
public void doX() {
// ...
}
}
</code></pre>
<p>My code works as expected, but I have a few questions:</p>
<ul>
<li><p>Should I declare the abstract Method doX() in Class B? Why (not)?</p></li>
<li><p>Should I also explicitly declare "implements A" on Class C and D? Why (not)?</p></li>
</ul>

352,527 | <p>I am adventuring into some AOP and it seems with .NET PostSharp is the way to go. </p>
<p>I want to do some simple logging to the db when an exception occurs. However I am finding it difficult to find any real solid examples of using PostSharp beyond the basics. I tried the following:</p>
<pre><code>[Serializable]
public sealed class LogExceptionAttribute : ExceptionHandlerAspect
{
public override void OnException(MethodExecutionEventArgs eventArgs)
{
//do some logging here
}
}
</code></pre>
<p>And then attaching a <code>[LogException]</code> attribute to a method</p>
<p>But I get a compile error:</p>
<pre><code>Error 7 The type "CoDrivrBeta1.Classes.LogExceptionAttribute" or one of its ancestor should be decorated by an instance of MulticastAttributeUsageAttribute. C:\work\CoDrivrBeta1\CoDrivrBeta1\EXEC CoDrivrBeta1
</code></pre>
<p>I have to confess I am very new to this, but it seems like an interesting concept, I think i just need to be pointed in the right direction</p>

352,532 | <p><strong>Questions</strong>:</p>
<ul>
<li>What does the kernel do if you stick a shell-script into the shebang line? </li>
<li>How does the Kernel know which interpreter to launch?</li>
</ul>
<p><strong>Explanation</strong>:</p>
<p>I recently wanted to write a wrapper around <em>/usr/bin/env</em> because my CGI Environment does not allow me to set the <em>PATH</em> variable, except globally (which of course sucks!).</p>
<p>So I thought, "OK. Let's set PREPENDPATH and set <em>PATH</em> in a wrapper around env.". The resulting script (here called <em>env.1</em>) looked like this:</p>
<pre><code>#!/bin/bash
/usr/bin/env PATH=$PREPENDPATH:$PATH $*
</code></pre>
<p>which looks like it should work. I checked how they both react, after setting PREPENDPATH:</p>
<pre><code>$ which /usr/bin/env python
/usr/bin/env
/usr/bin/python
$ which /usr/bin/env.1 python
/usr/bin/env
/home/pi/prepend/bin/python
</code></pre>
<p>Look absolutely <em>perfect</em>! So far, so good. But look what happens to "Hello World!".</p>
<pre><code># Shebang is #!/usr/bin/env python
$ test-env.py
Hello World!
# Shebang is #!/usr/bin/env.1 python
$ test-env.1.py
Warning: unknown mime-type for "Hello World!" -- using "application/*"
Error: no such file "Hello World!"
</code></pre>
<p>I guess I am missing something pretty fundamental about UNIX.</p>
<p>I'm pretty lost, even after looking at the source code of the original <em>env</em>. It sets the environment and launches the program (or so it seems to me...).</p>

352,535 | <p>Aloha</p>
<p>I have a VS2008 solution to which I want to add a webservice reference. I enter an url like '<a href="http://192.168.100.87:7001/wsdl/IMySOAPWebService" rel="nofollow noreferrer">http://192.168.100.87:7001/wsdl/IMySOAPWebService</a>'. The Add Web Reference dialog starts looking then throws me this error: </p>
<blockquote>
<p>There was an error downloading
'<a href="http://192.168.100.87:7001/wsdl/IMySOAPWebService/" rel="nofollow noreferrer">http://192.168.100.87:7001/wsdl/IMySOAPWebService/</a>$metadata'.</p>
</blockquote>
<p>Adding the exact same reference to a VS 2005 project works fine. Any clues?</p>

352,543 | <p>This is a bit of a long question, but here we go. There is a version of FormatDateTime that is said to be thread safe in that you use </p>
<pre><code>GetLocaleFormatSettings(3081, FormatSettings);
</code></pre>
<p>to get a value and then you can use it like so; </p>
<pre><code>FormatDateTime('yyyy', 0, FormatSettings);
</code></pre>
<p>Now imagine two timers, one using TTimer (interval say 1000ms) and then another timer created like so (10ms interval); </p>
<pre><code>CreateTimerQueueTimer
(
FQueueTimer,
0,
TimerCallback,
nil,
10,
10,
WT_EXECUTEINTIMERTHREAD
);
</code></pre>
<p>Now the narly bit, if in the call back and also the timer event you have the following code;</p>
<pre><code>for i := 1 to 10000 do
begin
FormatDateTime('yyyy', 0, FormatSettings);
end;
</code></pre>
<p>Note there is no assignment. This produces access violations almost immediatley, sometimes 20 minutes later, whatever, at random places. Now if you write that code in C++Builder it never crashes. The header conversion we are using is the JEDI JwaXXXX ones. Even if we put locks in the Delphi version around the code, it only delays the inevitable. We've looked at the original C header files and it all looks good, is there some different way that C++ uses the Delphi runtime? The thread safe version of FormatDatTime looks to be re-entrant. Any ideas or thoughts from anyone who may have seen this before.</p>
<p><strong>UPDATE:</strong></p>
<p>To narrow this down a bit, FormatSettings is passed in as a const, so does it matter if they use the same copy (as it turns out passing a local version within the function call yeilds the same problem)? Also the version of FormatDateTime that takes the FormatSettings doesn't call GetThreadLocale, because it already has the Locale information in the FormatSettings structure (I double checked by stepping through the code). </p>
<p>I made mention of no assignment to make it clear that no shared storage is being accessed, so no locking is required.</p>
<p>WT_EXECUTEINTIMERTHREAD is used to simplify the problem. I was under the impression you should only use it for very short tasks because it may mean it'll miss the next interval if it is running something long?</p>
<p>If you use a plain old TThread the problem doesn't occur. What I am getting at here I suppose is that using a TThread or a TTimer works but using a thread created outside the VCL doesn't, that's why I asked if there was a difference in the way C++ Builder uses the VCL/Delphi RTL.</p>
<p>As an aside this code as mentioned before also fails (but takes longer), after a while, CS := TCriticalSection.Create;</p>
<pre><code> CS.Acquire;
for i := 1 to LoopCount do
begin
FormatDateTime('yyyy', 0, FormatSettings);
end;
CS.Release;
</code></pre>
<p>And now for the bit I really don't understand, I wrote this as suggested;</p>
<pre><code>function ReturnAString: string;
begin
Result := 'Test';
UniqueString(Result);
end;
</code></pre>
<p>and then inside each type of timer the code is;</p>
<pre><code> for i := 1 to 10000 do
begin
ReturnAString;
end;
</code></pre>
<p>This causes the same kinds of failiures, as I said before the fault is never in the same place inside the CPU window etc. Sometimes it's an access violation and sometimes it might be an invalid pointer operation. I am using Delphi 2009 btw.</p>
<p><strong>UPDATE 2:</strong></p>
<p>Roddy (below) points out the Ontimer event (and unfortunately also Winsock, i.e. TClientSocket) use the windows message pump (as an aside it would be nice to have some nice Winsock2 components using IOCP and Overlapping IO), hence the push to get away from it. However does anyone know how to see what sort of thread local storage is setup on the CreateQueueTimerQueue?</p>
<p>Thanks for taking the time to think and answer this problem.</p>

352,552 | <p>My table has a large number of columns.

352,586 | <p>I have an existing database of a film rental system. Each film has a has a rating attribute. In SQL they used a constraint to limit the allowed values of this attribute.</p>
<pre><code>CONSTRAINT film_rating_check CHECK
((((((((rating)::text = ''::text) OR
((rating)::text = 'G'::text)) OR
((rating)::text = 'PG'::text)) OR
((rating)::text = 'PG-13'::text)) OR
((rating)::text = 'R'::text)) OR
((rating)::text = 'NC-17'::text)))
</code></pre>
<p>I think it would be nice to use a Java enum to map the constraint into the object world. But it's not possible to simply take the allowed values because of the special char in "PG-13" and "NC-17". So I implemented the following enum:</p>
<pre><code>public enum Rating {
UNRATED ( "" ),
G ( "G" ),
PG ( "PG" ),
PG13 ( "PG-13" ),
R ( "R" ),
NC17 ( "NC-17" );
private String rating;
private Rating(String rating) {
this.rating = rating;
}
@Override
public String toString() {
return rating;
}
}
@Entity
public class Film {
..
@Enumerated(EnumType.STRING)
private Rating rating;
..
</code></pre>
<p>With the toString() method the direction enum -> String works fine, but String -> enum does not work. I get the following exception:</p>
<blockquote>
<p>[TopLink Warning]: 2008.12.09

352,605 | <p>I'm trying to debug a rather complicated formula evaluator written in T-SQL UDFs (don't ask) that <strong>recursively</strong> (but indirectly through an intermediate function) calls itself, blah, blah.</p>
<p>And, of course, we have a bug.</p>
<p>Now, using PRINT statements (that can then be read from ADO.NET by implementing a handler for the InfoMessage event), I can simulate a trace for stored procedures.</p>
<p>Doing the same for UDF results in a compile time message:</p>
<pre><code>Invalid use of side-effecting or time-dependent operator in 'PRINT' within a function.
</code></pre>
<p>I get the message (PRINT does some stuff like resetting <code>@@ROWCOUNT</code> which definitly is a no-no in UDFs, but how can I trace through the calls? I want to have this trace printed out, so I can study it without getting distracted by stepping through the calls in the debugger...</p>
<p><strong>EDIT:</strong> I have tried to use the SQL Profiler (this was a first time one for me), but I can't figure out what to trace for: Although I can get the trace to output the queries sent to the database, they are opaque in the sense that I can't drill down to the Expression-UDFs called: I can trace the actual Stored Procedure invoked, but the UDFs called by this procedure are not listed. Am I missing something? I guess not...</p>
<p><strong>EDIT #2:</strong> Allthough the (auto-)accepted answer does trace the function calls - very helpful, thanks - it does not help in finding out what parameters were <em>passed</em> to the function. This, of course, is essential in <strong>debugging</strong> recursive functions. I will post if I find any sollution at all...</p>

352,612 | <p>I have a Maven pom that uses <code><packaging>war</packaging></code>. But actually, I don't want build the war-file, I just want all the dependent jars collected and a full deployment directory created.</p>
<p>So I'm running the <code>war:exploded</code> goal to generate the deploy directory:</p>
<pre><code><plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<executions>
<execution>
<phase>package</phase>
<configuration>
<webappDirectory>target/${env}/deploy</webappDirectory>
<archiveClasses>true</archiveClasses>
</configuration>
<goals>
<goal>exploded</goal>
</goals>
</execution>
</executions>
</plugin>
</code></pre>
<p>The trouble is, the war file still gets built. Is there a simple way of having <code><packaging>war</packaging></code> execute the <code>war:exploded</code> goal instead of the war:war goal?</p>
<p>Or is there another simple way to do this?</p>

352,618 | <p>From what I have read best practice is to have classes based on an interface and loosely couple the objects, in order to help code re-use and unit test.</p>
<p>Is this correct and is it a rule that should always be followed? </p>
<p>The reason I ask is I have recently worked on a system with 100’s of very different objects. A few shared common interfaces but most do not and wonder if it should have had an interface mirroring every property and function in those classes?</p>
<p>I am using C# and dot net 2.0 however I believe this question would fit many languages. </p>

352,623 | <p>I have to interface with a slightly archaic system that doesn't use webservices. In order to send data to this system, I need to post an XML document into a <i>form</i> on the other system's website. This XML document can get very large so I would like to compress it.
The other system sits on IIS and I use C# my end. I could of course implement something that compresses the data before posting it, but that requires the other system to change so it can decompress the data. I would like to avoid changing the other system as I don't own it. </p>
<p>I have heard vague things about enabling compression / http 1.1 in IIS and the browser but I have no idea how to translate that to my program. Basically, is there some property I can set in my program that will make my program automatically compress the data that it is sending to IIS and for IIS to seamlessly decompress it so the receiving app doesn't even know the difference? </p>
<p>Here is some sample code to show roughly what I am doing; </p>
<pre><code>private static void demo()
{
Stream myRequestStream = null;
Stream myResponseStream = null;
HttpWebRequest myWebRequest = (HttpWebRequest)System.Net
.WebRequest.Create("http://example.com");
byte[] bytMessage = null;
bytMessage = Encoding.ASCII.GetBytes("data=xyz");
myWebRequest.ContentLength = bytMessage.Length;
myWebRequest.Method = "POST";
// Set the content type as form so that the data
// will be posted as form
myWebRequest.ContentType = "application/x-www-form-urlencoded";
//Get Stream object
myRequestStream = myWebRequest.GetRequestStream();
//Writes a sequence of bytes to the current stream
myRequestStream.Write(bytMessage, 0, bytMessage.Length);
//Close stream
myRequestStream.Close();
WebResponse myWebResponse = myWebRequest.GetResponse();
myResponseStream = myWebResponse.GetResponseStream();
}
</code></pre>
<p>"data=xyz" will actually be "data=[a several MB XML document]".</p>
<p>I am aware that this question may ultimately fall under the non-programming banner if this is achievable through non-programmatic means so apologies in advance.</p>

352,632 | <p>I'm making a WPF application that is comprised of Screens (Presenter + View). I want to be able to declare these screens in a config file or SQL database. I have been trying to come up with a good solution I've given up and am asking how some of you design this sort of thing? I've been working at this for over a week and every solution I come up with stinks.</p>
<p>In my WPF application I have a treeview that represents screens. When the user clicks on a node, the screen is loaded. I want to be able to populate the treenodes from a config file or database. The program should not care where these are stored so I can swap out a config store for a database store. If I have the screen info stored I can also use an IOC container to instantiate the screens for me and retrieve them by name. Here is a sample of the config file schema that I have come up with:</p>
<pre><code><screen name="" title="" presenterType="" viewType=""/>
<screen ...>
<screen .../>
<screen .../>
</screen>
<screen .../>
</code></pre>
<p>The latest solution I have come up with is to use a ScreenService that asks a ScreenRepository for ScreenInfo objects. Then I will be able to populate the treeview and IOC container with this information.</p>
<p>Does this sound like a good solution? What would you do different? And, how do you design this sort of system in your own programming?</p>

352,633 | <p>I need to write a script to set ip address/mask/broadcast as an alias on eth0:0 plus set the default gateway.</p>
<p>This solution works:</p>
<pre><code>ifconfig eth0:0 <ip> netmask <mask> up
ip route replace default via <ip>
</code></pre>
<p>but sometimes the second call gets an error "network unavailable".</p>
<p>Adding a sleep between them fixes it, but is unreliable. What is the proper way to wait for the network to be ready?</p>
<p>The best I came up with so far is retrying the ip call a couple times. This works, but feels ugly. </p>

352,638 | <p>What do you think is the best way for obtaining the results of the work of a thread? Imagine a Thread which does some calculations, how do you warn the main program the calculations are done?</p>
<p>You could poll every X milliseconds for some public variable called "job finished" or something by the way, but then you'll receive the results later than when they would be available... the main code would be losing time waiting for them. On the other hand, if you use a lower X, the CPU would be wasted polling so many times.</p>
<p>So, what do you do to be aware that the Thread, or some Threads, have finished their work?</p>
<p>Sorry if it looks similar to this other <a href="https://stackoverflow.com/questions/289434/how-to-make-a-java-thread-wait-for-another-threads-output">question</a>, that's probably the reason for the <em>eben</em> answer, I suppose. What I meant was running lots of threads and know when all of them have finished, without polling them.</p>
<p>I was thinking more in the line of sharing the CPU load between multiple CPU's using batches of Threads, and know when a batch has finished. I suppose it can be done with <strong>Future</strong>s objects, but that blocking <em><strong>get</strong></em> method looks a lot like a hidden lock, not something I like.</p>
<p>Thanks everybody for your support. Although I also liked the answer by <em><strong>erickson</strong></em>, I think <em><strong>saua</strong></em>'s the most complete, and the one I'll use in my own code.</p>

352,654 | <p>I've added a proxy to a webservice to a VS2008/.NET 3.5 solution. When constructing the client .NET throws this error:</p>
<blockquote>
<p>Could not find default endpoint element that references contract 'IMySOAPWebService' in the ServiceModel client configuration section. This might be because no configuaration file was found for your application or because no endpoint element matching this contract could be found in the client element.</p>
</blockquote>
<p>Searching for this error tells me to use the full namespace in the contract. Here's my app.config with full namespace:</p>
<pre><code><client>
<endpoint address="http://192.168.100.87:7001/soap/IMySOAPWebService"
binding="basicHttpBinding" bindingConfiguration="IMySOAPWebServicebinding"
contract="Fusion.DataExchange.Workflows.IMySOAPWebService" name="IMySOAPWebServicePort" />
</client>
</code></pre>
<p>I'm running XP local (I mention this because a number of Google hits mention win2k3)
The app.config is copied to app.exe.config, so that is also not the problem.</p>
<p>Any clues?</p>

352,670 | <p>Recently I needed to do weighted random selection of elements from a list, both with and without replacement. While there are well known and good algorithms for unweighted selection, and some for weighted selection without replacement (such as modifications of the resevoir algorithm), I couldn't find any good algorithms for weighted selection with replacement. I also wanted to avoid the resevoir method, as I was selecting a significant fraction of the list, which is small enough to hold in memory.</p>
<p>Does anyone have any suggestions on the best approach in this situation? I have my own solutions, but I'm hoping to find something more efficient, simpler, or both.</p>

352,673 | <p>I know I can update a single record like this - but then how to I get access to the id of the record that was updated? (I'm using MSSQL so I can't use Oracles RowId)</p>
<pre><code>update myTable
set myCol = 'foo'
where itemId in (select top 1 itemId from myTable )
</code></pre>
<p>If I was peforming an Insert I could use getGeneratedKeys to get the id field value, but I don't think there is an equivalent for an update?</p>
<p>I know I can use a scrollable resultset to do what I want</p>
<p>i.e.</p>
<pre><code>stmt = conn.prepareStatement("select top 1 myCol, itemId from myTable", ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_UPDATABLE);
ResultSet resultSet = stmt.executeQuery();
if(resultSet.first()){
resultSet.updateString(1, "foo");
resultSet.updateRow();
String theItemId = resultSet.getString(1)
}
resultSet.close();
</code></pre>
<p>but I'm concerned about performance as testing shows lock timeouts under load and I was wondering if there was a better/simpler way?</p>
<p>-- EDIT:
Just to finalise this issue...
When we migrate to MSSQL2005 we will upgrade our code to use Rich's answer.
In the current release we have used the lock hints: (UPDLOCK ROWLOCK READPAST) to mitigate the performance problems our original code showed. </p>

352,703 | <p>Is it possible to integrate <a href="http://hudson.dev.java.net/" rel="noreferrer" title="hudson: an extensible continuous integration engine">Hudson</a> with MS Test?</p>
<p>I am setting up a smaller CI server on my development machine with Hudson right now, just so that I can have some statistics (ie. <a href="http://blogs.msdn.com/fxcop/" rel="noreferrer" title="Code Analysis Team Blog">FxCop</a> and compiler warnings). Of course, it would also be nice if it could just run my unit tests and present their output.</p>
<p>Up to now, I have added the following batch task to Hudson, which makes it run the tests properly.</p>
<pre><code>"%PROGRAMFILES%\Microsoft Visual Studio 9.0\Common7\IDE\MSTest.exe" /runconfig:LocalTestRun.testrunconfig /testcontainer:Tests\bin\Debug\Tests.dll
</code></pre>
<p>However, as far as I know, Hudson does not support analysis of MS Test results, yet. Does anyone know whether the TRX files generated by <code>MSTest.exe</code> can be transformed to the <a href="http://www.junit.org/" rel="noreferrer">JUnit</a> or <a href="http://www.nunit.org/" rel="noreferrer">NUnit</a> result format (because those are supported by Hudson), or whether there is any other way to integrate MS Test unit tests with Hudson?</p>

<li>For each line does a lot of calculations which implies reading dozens of tables and write the results into a temporary (#temp) table (process that last several minutes).</li>
<li>Deletes the lines in "LoadDate" for the specific LoadId.</li>
<li>Once everything is done, write the result in the result table.</li>
</ul></li>
<li>Commit transaction or rollback if something fails.</li>
</ul>
<p>My problem is that if I have 2 users that start the process, the second one will have to wait that the previous has finished (because the insert seems to put an exclusive lock on the table) and my application sometimes falls in timeout (and the users are not happy to wait :) ).</p>
<p>I'm looking for a way to be able to have the users that does everything in parallel as there is no interaction, except the last one: writing the result. I think that what is blocking me is the inserts / deletes in the "LoadData" table.
I checked the other transaction isolation levels but it seems that nothing could help me.</p>
<p>What would be perfect would be to be able to remove the exclusive lock on the "LoadData" table (is it possible to force SqlServer to only lock rows and not table ?) when the Insert is finished, but without ending the transaction.</p>
<p>Any suggestion?</p>

352,752 | <p>My application is developped in C++ using Qt and is using signals and slots.</p>
<p>Let's say I have the following classes (pseudo-C++ code) :</p>
<pre><code>class Ball
{
Color m_Color;
int m_Size;
};
class Player
{
public:
setBall(Ball* pBall)
{
if (pBall != m_pBall)
{
Ball* pPreviousBall = m_pBall;
m_pBall = pBall;
emit notifyBallNotUsed(pPreviousBall);
}
}
Ball* getBall();
signals:
void notifyBallNotUsed(Ball*);
private:
String m_Name;
Ball* m_pBall;
};
class GeneralHandler
{
public:
addBall(Ball* pBall);
deleteBall(Ball* pBall);
addPlayer(Player* pPlayer)
{
connect(pPlayer, SIGNAL(notifyBallNotUsed(Ball*)), this, SLOT(onBallUsageChanged(Ball*)));
...
}
deletePlayer(Player* pPlayer);
{
disconnect(pPlayer, SIGNAL(notifyBallNotUsed(Ball*)), this, SLOT(onBallUsageChanged(Ball*)));
onBallUsageChanged(pPlayer->getBall());
....
}
private slots:
void onBallUsageChanged(Ball* pBall)
{
if (isNotUsedAnymore(pBall))
{
m_BallList.remove(pBall);
delete pBall;
}
}
private:
bool isNotUsedAnymore(Ball* pBall); // Check if the given ball is still used by at least one player
List<Player*> m_PlayerList;
List<Ball*> m_BallList;
};
</code></pre>
<p>With my application, the user can add/remove player, and for each player, decide the color and the size of the ball. Behind the hood, the GeneralHandler is in charge to store the balls and delete them.
It is perfectly possible that two players are using the same ball.</p>
<p>When a player is deleted, if the ball is not used anymore, the GeneralHandler should delete it (or keep it if the ball is still used by another player).
If the ball a player is using is changed, the previous ball, if not used anymore, should be deleted by the GeneralHandler as well.</p>
<p>So far so good.</p>
<p>Now, I want to add undo/redo capability to my application, using the command pattern, and this is where I'm stuck. Lets say I have something like this :</p>
<pre><code>class ChangePlayerBall : public QUndoCommand
{
public:
ChangePlayerBall(Player* pPlayer, Ball* pNewBall)
{
m_pPlayer = pPlayer;
}
void redo();
void undo();
private:
Player* m_pPlayer;
};
</code></pre>
<p>I guess the redo() method will look like this :</p>
<pre><code>void ChangePlayerBall::redo()
{
m_pPlayer->setBall(pNewBall);
}
</code></pre>
<p>If nothing else is changed in the code above, the previous Ball will be deleted if not used anymore by other players.
This will be a problem when implementing the undo() method : if the previous ball has been deleted, I don't know what was it's characteristics and the undo command won't be able to recreate it.
Or maybe I should store the previous ball, but how will the undo/redo command know if this previous ball is still existing or has been deleted by the handler ?
Or maybe this mechanism of deleting a ball as soon as it isn't used anymore should be implemented in the undo command ? The problem is that the undo command will have a lot of dependencies on many other classes. The other problem is that this code would be partially duplicated in the DeletePlayer command, which will have to do something similar :</p>
<pre><code>class DeletePlayer : public QUndoCommand
{
public:
DeletePlayer(Player* pPlayer);
void redo();
void undo();
...
};
</code></pre>
<p>I hope my explainations where understandable !</p>
<p>How would you solve this problem ? I cannot find a satisfying solution.</p>
<p>Thanks !</p>

<p>When I'm writing long argument lists ReSharper sensibly chops the parameter list and restarts it on the next line. I find that much more readable.</p>
<p>When I run StyleCop over the code it wants me to leave those lines really long. I don't like that, so I want to ignore that StyleCop rule (SA1115). I can't think of a good reason why SC would want those long lines in the first place – is it just a case of "we've always done it this way"?</p>

352,832 | <p>May be my title is not clear. I am looking for some kind of version control on database tables, like subversion does on files, like wiki does.</p>
<p>I want to trace the changes log.
I want to extract and run the diff in reverse. (undo like a "svn merge -r 101:100").
I may need a indexed search on the history.</p>
<p>I've read the "<a href="https://stackoverflow.com/questions/49755/design-pattern-for-undo-engine">Design Pattern for Undo Engine</a>", but it is related to "Patterns". Are there anything I could reuse without reinvent the wheel?</p>
<p><strong>EDIT:</strong>
For example, bank account transactions. I have column "balance"(and others) updated in table. a user will find a mistake by him 10 days later, and he will want to cancel/rollback the specific transaction, without changing others.</p>
<p>How can I do it gracefully in the application level?</p>

352,837 | <p>This is a question regarding Unix shell scripting (any shell), but any other "standard" scripting language solution would also be appreciated:</p>

fec8047a9186fdcc98fdbfc0ea6075ee
</code></pre>
<p>These files have different original file types such as png, zip, doc, pdf etc.</p>
<p>Can anybody provide a script that would rename the files so they get their appropriate file extension, probably based on the output of the <code>file</code> command?</p>

<p><a href="https://stackoverflow.com/questions/352837/how-to-add-file-extensions-based-on-file-type-on-linuxunix#352973">J.F. Sebastian's</a> script will work for both ouput of the filenames as well as the actual renaming.</p>

352,839 | <p>I need to create a DHTML menu with the specified features, but I can't figure out how to do it. Here's what I need:</p>
<p>All items are layed out horizontally. If they would be wider than the screen, two little arrows appear on the right side of the menu that allow to scroll it. Something like this:</p>
<pre><code>+--------+--------+-------+---+---+
| Item 1 | Item 2 | Item 3| < | > |
+--------+--------+-------+---+---+
</code></pre>
<p>Menu items should be clickable anywhere in the cell. They should stretch both vertically and horizontally to the contents. The text in the items should be centered both vertically and horizontally. The menu should work in IE7/Opera/FF/Safari.</p>
<p>The scrolling is the easy part - I just place it all in a container (say, a <code><div></code>), set the container to <code>overflow: hidden</code> and then play around in Javascript with <code>clientWidth</code>, <code>scrollWidth</code> and <code>scrollLeft</code>. That I've figured out and have already tried.</p>
<p>But how to make the menu items so stretchy, clickable anywhere and centered text?</p>

<p>I usually have a set of specific exception classes (DivideByZeroException, ArrayTypeMismatchException) and don't have a generic "catch (Exception ex)".</p>

352,906 | <h2>Scenario</h2>
<p>You've got several bug reports all showing the same problem. They're all cryptic with similar tales of how the problem occurred. You follow the steps but it doesn't reliably reproduce the problem. After some investigation and web searching, you suspect what might be going on and you are pretty sure you can fix it.</p>
<h2>Problem</h2>
<p>Unfortunately, without a reliable way to reproduce the original problem, you can't verify that it actually fixes the issue rather than having no effect at all or exacerbating and masking the real problem. You could just not fix it until it becomes reproducible every time, but it's a big bug and not fixing it would cause your users a lot of other problems.</p>
<h2>Question</h2>
<p>How do you go about verifying your change?</p>
<p>I think this is a very familiar scenario to anyone who has engineered software, so I'm sure there are a plethora of approaches and best practices to tackling bugs like this. We are currently looking at one of these problems on our project where I have spent some time determining the issue but have been unable to confirm my suspicions. A colleague is soak-testing my fix in the hopes that "a day of running without a crash" equates to "it's fixed". However, I'd prefer a more reliable approach and I figured there's a wealth of experience here on SO.</p>

I also checked out a previous version from my svn which should work. What I noticed that the <code>displayname</code> (I use a german version of Tomcat , so I guess that is how I would translate it, the name in the second column in the Tomcat manager) disappeared. I use Eclipse Ganymede on vista. Tomcat is running on Debian. A local Tomcat shows the same behavior.

352,949 | <p>I've got two tables that need to be joined via LINQ, but they live in different databases. Right now I'm returning the results of one table, then looping through and retrieving the results of the other, which as you can guess isn't terribly efficient. Is there any way to get them into a single LINQ statement? Is there any other way to construct this to avoid the looping? I'm just looking for ideas, in case I'm overlooking something.</p>
<p>Note that I can't alter the databases, i.e. I can't create a view in one that references the other. Something I haven't tried yet is creating views in a third database that references both tables. Any ideas welcome.</p>

352,991 | <p>How can I do for inserting a Default Value into a column of a table in Access?
I use this instruction:</p>
<pre><code>ALTER TABLE Tabella ADD Campo Double DEFAULT 0
ALTER TABLE Tabella ADD Campo Double DEFAULT (0)
ALTER TABLE Tabella ADD Campo DEFAULT 0
ALTER TABLE Tabella ADD Campo DEFAULT (0)
ALTER TABLE Tabella ADD Campo SET DEFAULT 0
ALTER TABLE Tabella ADD Campo SET DEFAULT (0)
</code></pre>
<p>but all of these cause error. How can I do for doing it?</p>

352,997 | <p>I would appreciate your opinion/advice on the following</p>
<p><strong>Scenario</strong> </p>
<p>HTML has PDF file nick name, back end has URL for each nick. </p>
<p>The link URL is always <code>download.php?what=%PDF_Nick%</code> to ensure download for JS disabled clients. </p>
<p>For JS enabled clients I do JQuery AJAX call and rewrite link URL from <code>download.php?what=%PDF_Nick%</code> to <a href="http://examplesite.com/requestedPFF.pdf" rel="nofollow noreferrer">http://examplesite.com/requestedPFF.pdf</a> to activate download from the client. I set <code>"async: false"</code> to allow AJAX get new url.</p>
<p><strong>Problem</strong></p>
<p>AJAX returns valid script rewriting JS url variable, but <code>location.href</code> runs again to the initial url, creating extra back end call</p>
<p>Do you think it's related to the bug ignoring <code>"async: false,"</code> definition or it's mistake I've made and missed to catch?</p>
<p>Thank you in advance</p>
<h1>HTML code</h1>
<pre><code>
<a href="/download.php?what=PDF_A" onclick="javascript:download
('PDF_A')">Download</a>
</code></pre>
<h1>JS code</h1>
<pre><code>function download ( what ) {
var url = "download.php?what="+what;
$.ajax({
type: "GET",
url: "download.php?ajax=true",
data: "what=" + what
async: false,
dataType: "script"
});
// if AJAX got the download URL I expect actual download to start:
location.href = url;
}
</code></pre>
<h1>Back end (download.php) code</h1>
<pre><code>$myPDF = array();
$myPDF["PDF_A"] = "PDF_A.pdf";
....
$url = "http://examplesite.com/" . $myPDF["PDF_A"];
...
if ( $_GET["ajax"] === "true" ) {
// overwrite JS url variable
print('url = "'.$url.'";');
} else {
header("Location: ". $url );
header("Connection: close");
}

353,013 | <p>I'm trying to abstract out all database code into a separate library and then use that library in all my code. All database connections are done using typed TableAdapters that I create by dragging and dropping in datasets in VS2005, using a connection string from the appSettings.</p>
<p>The problem that I haven't been able to solve is that .Net doesn't propagate the libraries appSettings to the other project that's using it.</p>
<p>In short, I have a database layer library, MyProgram.DbLayer, which is used by other projects such as MyProgram.Client etc. When I had all the datasets in the .Client the connectionString was in MyProgram.Client.exe.config so that I could change it after build. When I moved it into the MyProgram.DbLayer that setting isn't avaliable to me after I build the binaries.</p>
<p>EDIT:
This seems to be a more general issue with ApplicationSettings.</p>
<p>What I noticed was that if I manually add a setting only used in a library it will be properly read. The only thing I need now is for the setting to be automatically included in the .config file as well.</p>

353,014 | <p>I've been doing a <code>convert(varchar,datefield,112)</code> on each date field that I'm using in 'between' queries in SQL server to ensure that I'm only accounting for dates and not missing any based on the time part of datetime fields.</p>
<p>Now, I'm hearing that the converts aren't indexable and that there are better methods, in SQL Server 2005, to compare the date part of datetimes in a query to determine if dates fall in a range.</p>
<p>What is the optimal, indexable, method of doing something like this:</p>
<pre><code>select * from appointments
where appointmentDate>='08-01-2008' and appointmentDate<'08-15-2008'

353,019 | <p>I have a query that runs super fast when executed in the sql editor (oracle): 1ms.</p>
<p>The same query (as stored procedure) when executed by a DataSet-TableAdapter takes 2 seconds. I'm just retrieving 20rows.</p>
<p>Since I'm using a TableAdapter, the return values are stored in a ref cursor.</p>
<p>If I was fetching 2'000 rows I could understand that some time is needed to build the DataSet, but 2 seconds for only 20 rows seems too much for me.</p>
<p>There is a better way to execute SP on oracle or this is the only way?
What could I try to do to improve the performances?</p>
<p>Thanks for your help!</p>
<hr>
<p>Searching in google, it seems that the problem is with the refcursor. Others people faced the same performance issue, but no solution is provided.</p>

353,020 | <p>I would need to create a temp table for paging purposes. I would be selecting all records into a temp table and then do further processing with it.</p>
<p>I am wondering which of the following is a better approach:</p>
<p>1) Select all the columns of my Primary Table into the Temp Table and then being able to select the rows I would need</p>
<p>OR</p>
<p>2) Select only the primary key of the Primary Table into the Temp Table and then joining with the Primary Table later on?</p>
<p>Is there any size consideration when working with approach 1 versus approach 2?</p>
<p>[EDIT]</p>
<p>I am asking because I would have done the first approach but looking at PROCEDURE [dbo].[aspnet_Membership_FindUsersByName], that was included with ASP.NET Membership, they are doing Approach 2</p>
<p>[EDIT2]</p>
<p>With people without access to the Stored procedure:</p>
<pre><code> -- Insert into our temp table
INSERT INTO #PageIndexForUsers (UserId)
SELECT u.UserId
FROM dbo.aspnet_Users u, dbo.aspnet_Membership m
WHERE u.ApplicationId = @ApplicationId AND m.UserId = u.UserId AND u.LoweredUserName LIKE LOWER(@UserNameToMatch)
ORDER BY u.UserName
SELECT u.UserName, m.Email, m.PasswordQuestion, m.Comment, m.IsApproved,
m.CreateDate,
m.LastLoginDate,
u.LastActivityDate,
m.LastPasswordChangedDate,
u.UserId, m.IsLockedOut,
m.LastLockoutDate
FROM dbo.aspnet_Membership m, dbo.aspnet_Users u, #PageIndexForUsers p
WHERE u.UserId = p.UserId AND u.UserId = m.UserId AND
p.IndexId >= @PageLowerBound AND p.IndexId <= @PageUpperBound
ORDER BY u.UserName

353,039 | <p>I'm writing some code to scale a 32 bit RGBA image in C/C++. I have written a few attempts that have been somewhat successful, but they're slow and most importantly the quality of the sized image is not acceptable. </p>
<p>I compared the same image scaled by OpenGL (i.e. my video card) and my routine and it's miles apart in quality. I've Google Code Searched, scoured source trees of anything I thought would shed some light (SDL, Allegro, wxWidgets, CxImage, GD, ImageMagick, etc.) but usually their code is either convoluted and scattered all over the place or riddled with assembler and little or no comments. I've also read multiple articles on Wikipedia and elsewhere, and I'm just not finding a clear explanation of what I need. I understand the basic concepts of interpolation and sampling, but I'm struggling to get the algorithm right. I do NOT want to rely on an external library for one routine and have to convert to their image format and back. Besides, I'd like to know how to do it myself anyway. :)</p>
<p>I have seen a similar question asked on stack overflow before, but it wasn't really answered in this way, but I'm hoping there's someone out there who can help nudge me in the right direction. Maybe point me to some articles or pseudo code... anything to help me learn and do.</p>
<p>Here's what I'm looking for:</p>
<ol>
<li>No assembler (I'm writing very portable code for multiple processor types).</li>
<li>No dependencies on external libraries.</li>
<li>I am primarily concerned with scaling DOWN, but will also need to write a scale up routine later.</li>
<li>Quality of the result and clarity of the algorithm is most important (I can optimize it later).</li>
</ol>
<p>My routine essentially takes the following form:</p>
<pre><code>DrawScaled(uint32 *src, uint32 *dst,
src_x, src_y, src_w, src_h,
dst_x, dst_y, dst_w, dst_h );
</code></pre>
<p>Thanks!</p>
<p><strong>UPDATE:</strong> To clarify, I need something more advanced than a box resample for downscaling which blurs the image too much. I suspect what I want is some kind of bicubic (or other) filter that is somewhat the reverse to a bicubic upscaling algorithm (i.e. each destination pixel is computed from all contributing source pixels combined with a weighting algorithm that keeps things sharp.</p>
<h2>Example</h2>
<p>Here's an example of what I'm getting from the wxWidgets BoxResample algorithm vs. what I want on a 256x256 bitmap scaled to 55x55.</p>
<ul>
<li>www.free_image_hosting.net/uploads/1a25434e0b.png</li>
</ul>
<p>And finally: </p>

</ul>

353,040 | <p>I want to list (a sorted list) all my entries from an attribute called streetNames in my table/relation Customers.
eg. I want to achieve the following order: </p>
<p>Street_1A<br>
Street_1B<br>
Street_2A<br>
Street_2B<br>
Street_12A<br>
Street_12B </p>
<p>A simple order by streetNames will do a lexical comparision and then Street_12A and B will come before Street_2A/B, and that is not correct. Is it possible to solve this by pure SQL?</p>

353,100 | <p>The below <a href="http://docs.jquery.com/Effects/fadeIn" rel="nofollow noreferrer">fadeIn</a>, <a href="http://docs.jquery.com/Effects/fadeOut" rel="nofollow noreferrer">fadeOut</a> effect works fine in Firefox 3.0 but it doesn't work in IE 7 ... Whay is that and what's the trick? The idea is of course to get a "blink" effect and attract the attention of the user to a specific row in a table. </p>
<pre><code>function highLightErrorsAndWarnings() {
$(".status-error").fadeIn(100).fadeOut(300).fadeIn(300).fadeOut(300).fadeIn(300).fadeOut(300).fadeIn(300);
$(".status-warning").fadeIn(100).fadeOut(300).fadeIn(300).fadeOut(300).fadeIn(300).fadeOut(300).fadeIn(300);
}
</code></pre>
<p><strong>Update:</strong> Found the stupid problem ... ".status-error" points to a tr-element. It's possible to the set the background-color and fade it on a tr in Firefox but not in IE. Changing the "CSS pointer" to ".status-error <strong><em>td</em></strong>" made it point to the td below the tr and everything worked in all browsers.</p>

353,110 | <p>Is it possible to exclude a complete namespace from all FxCop analysis while still analyzing the rest of the assembly using the <code>SuppressMessageAttribute</code>?</p>
<p>In my current case, I have a bunch of classes generated by LINQ to SQL which cause a lot of FxCop issues, and obviously, I will not modify all of those to match FxCop standards, as a lot of those modifications would be gone if I re-generated the classes.</p>
<p>I know that FxCop has a project option to suppress analysis on generated code, but it does not seem to recognize the entity and context classes created by LINQ 2 SQL as generated code.</p>

There is a method that will do this, I believe in a class called something like HTTPUtility or similar name. Though ever time I need this method, it takes me hours searching for it. It would be greatly appreciated if someone could post the proper method to do this so I can favorite this for easy access in the future. </p>
<p>Thank you very much. </p>

353,224 | <p>I'm brand new to Erlang. How do you do modulo (get the remainder of a division)? It's % in most C-like languages, but that designates a comment in Erlang.</p>
<p>Several people answered with rem, which in most cases is fine. But I'm revisiting this because now I need to use negative numbers and rem gives you the remainder of a division, which is not the same as modulo for negative numbers.</p>

353,288 | <p>I just started diving into ADO.NET Data Services for a project, and I quickly ran into a problem. At first I was amazed by the performance, but then I realized that the data was cached. My project relies on real-time data, and I'd love to use the ADO.NET Data Services REST query syntax (without needing to use WCF or SOAP), but without caching.</p>
<p>I saw on the ADO.NET Data Services introduction page (<a href="http://msdn.microsoft.com/en-us/library/cc907912.aspx" rel="nofollow noreferrer">here</a>) that they do not yet have API support for managing the cache duration or anything of the like.</p>
<p>Anyone have any ideas of how to accomplish this, or turn off the cache?</p>

353,296 | <p>I have a set of objects which I iterate through, however I may decide during the iteration that one (or more) of those objects now need to be deleted. </p>

353,336 | <p>I'm completely at loss how the ant task ivy:publish is supposed to work.</p>
<p>I would expect that I do my normal build, which creates a bunch of jar files, then I would push those jars to the (local) repository.</p>
<p>How can I specify from where to retrieve the built jars, and how would those end up in the repository?</p>
<p><strong>Update:</strong></p>
<pre><code><target name="publish-local" description="--> Publish Local">
<ivy:retrieve />
<ivy:publish resolver="local" pubrevision="${release.version}" status="release" update="true" overwrite="true">
<artifacts pattern="${dist.dir}/[organisation]-[module].[ext]" />
</ivy:publish>
</target>
</code></pre>
<p>this actually works, I didn't include the retrieve before. </p>
<p>But I still have some problems, suppose I want to publish 3 jars, openscada-utils.jar, openscada-utils-sources.jar and openscada-utils-javadocs.jar as openscada-utils-0.9.2.jar, openscada-utils-0.9.2-sources.jar and openscada-utils-0.9.2-javadocs.jar</p>
<p>It isn't entirely clear to me, how the actual names are assembled, and where I can specify which names they should get. (Using the fragment above, the jars are always called only utils.jar).</p>
<p><strong>Update 1:</strong></p>
<p>I got it to work (a bit), but it still doesn't feel right. Somehow all tutorials focus on dependencies from 3rd party projects, but an equally important point for me is to handle project specific dependencies.</p>
<p>I have a bunch of sub projects which depend on each other in various ways. Considering ivy:publish it is not clear to me how to start.</p>
<ol>
<li><p>How do I handle the first version? I have a common version number for all sub projects to indicate that they belong together (lets say 0.9). Therefore the first revision should be 0.9.0, but so far nothing of my projects is in my repository. How do I get Ivy to assign this revision number.</p></li>
<li><p>In the course of developing I want to publish the built files again, without changing the revision number so far.</p></li>
<li><p>If I'm finished with my work I want to push it to a shared repository (and increase the revision number lets say from 0.9.0 to 0.9.1), what is the recommended approach to do so?</p></li>
<li><p>For an actual release, I want to make distributions with dependencies and without, somehow I guess I can use different configurations for that. How can I use that to my advantage?</p></li>

353,342 | <p>We have lots of logging calls in our app. Our logger takes a System.Type parameter so it can show which component created the call. Sometimes, when we can be bothered, we do something like:</p>

private static readonly Type myType = typeof(Foo);
void SomeMethod()
{
Logger.Log(myType, "SomeMethod started...");
}
}

<p>As this requires getting the Type object only once. However we don't have any actual metrics on this. Anyone got any idea how much this saves over calling this.GetType() each time we log?</p>

&rft.au=Kingsley, Charles,
&rft.pages=1-352
&rft.tpages=352
&rft.date=1871
</code></pre>
<p>(Yes, I know it's ugly, welcome to my world). Note that the key "rft_id" appears twice:</p>
<ol>
<li><code>rft_id=info:oclcnum/1903126</code></li>
<li><code>rft_id=http://www.biodiversitylibrary.org/bibliography/4323</code></li>
</ol>
<p><code>$_GET</code> will return just <code>http://www.biodiversitylibrary.org/bibliography/4323</code>, the earlier value (<code>info:oclcnum/1903126</code>) having been overwritten.</p>
<p>I'd like to get access to both values. Is this possible in PHP? If not, any thoughts on how to handle this problem?</p>

353,380 | <p>I realize there's no definitely "right" answer to this question, but when people talk about lines of code, what do they mean? In C++ for example, do you count blank lines? Comments? Lines with just an open or close brace?</p>
<p>I know some people use lines of code as a productivity measure, and I'm wondering if there is a standard convention here. Also, I think there's a way to get various compilers to count lines of code - is there a standard convention there?</p>

353,414 | <p>I have inherited an ASP.NET 2.0 project and one of the things I have noticed is that the user has to click a <code>dropdownlist</code> twice in order to expand it - why is this?</p>
<p><strong>Sequence of Events</strong></p>
<ol>
<li>The first click with give the control focus and the second will expand it.</li>
<li>The application uses Master/Content pages and is Ajax enabled.</li>
</ol>
<p>It looks like this doesn't happen in IE6, but does happen in IE7.</p>

353,421 | <p>I'm trying to debug an ASP.Net web project that I received. I modified a class in the <code>"Apps_LocalResources"</code> folder. </p>
<p>When I debug and the code tries to step into that class, I get </p>
<blockquote>
<p>"The source file is different from when the module was built.". </p>
</blockquote>
<p>I rebuilt the solution and didn't get any change. I even published it to a different location and the pdb and dll in the bin folder didn't change so I didn't copy them over. </p>
<p>Ideas?</p>

353,425 | <p>I have a Stored Procedure called spGetOrders which accepts a few parameters: @startdate and @enddate. This queries an "Orders" table. One of the columns in the table is called "ClosedDate". This column will hold NULL if an order hasn't been closed or a date value if it has. I'd like to add a @Closed parameter which will take a bit value. In a simple world, I'd be able to do.. </p>
<pre><code>select * from orders o
where o.orderdate between @startdate AND @enddate
and (if @Closed = 1 then o.ClosedDate IS NULL else o.ClosedDate IS NOT NULL)
</code></pre>
<p>Obviously, that's not going to work.. I'm also looking at dynamic sql which is my last resort, but starting to look like the answer.. </p>
<p>Please help.. </p>

353,430 | <p>I'm building a custom property grid that displays the properties of items in a collection. What I want to do is show only the properties in the grid that are common amongst each item. I am assuming the best way to do this would be to find the the common base class of each type in the collection and display it's properties. Is there any easier way? Can you give me a code example of the best approach to do this?</p>

353,481 | <p>I know this is particularly difficult with CSS and the current set of browsers, but nonetheless I have the requirement.</p>
<p>I need to be able to have 3 divs in a column. Each div should be able to take up a certain percentage of the vertical space (for example, 33%). The contents of each div <em>could</em> end up being larger than the available space, so the div should be able to overflow and give the user scrollbars.</p>
<p>My problem is that I'm having trouble figuring out how to give each panel that vertical height. Any ideas?</p>
