i found my problem
my problem is the application is not read the connection string in app.config so when i start with debugging, it is all write but when start without debugging the exception is thrown
another thing
when i clear the comming from machine.config as the following code
<configuration>
<clear/>
<connectionStrings>
<add name="ConnectionString"
connectionString="Data Source=.;Initial Catalog='Computer Sales System';Integrated Security=True"/>
</connectionStrings>
</configuration>
the exception is thrown in both sides
so
i understand that the connection string in app.config is not read by application
so i want to know why???????? and what is the solution for this problem
thanks

Don't use app.config -- write your own configuration file.

<clear/> should appear between <connectionStrings> and </connectionStrings>

Wow. I honestly assumed someone had posted this as a joke.
Yes, Windows 7 means we need to rewrite all our programs in F#, and all our program windows will go a horrible shade of green. This is a dumb question. Why would Microsoft release a new platform on which our existing programs would not work ?

Because they've done it six or seven times already?

Really?!?!?
I think they have a much better record at backward compatibility than, say, apple....

That may or may not be the case, but it's certainly the case that some programs have certain compatibility issues with W7.
In my case, Visual Studio 2008 is one of them. With UAC enabled I cannot launch it as Administrator (i.e. with Administrator as the process identity, as opposed to simply launching it while being logged on as Administrator). To log on to IIS locally I must run it as Administrator, so I eventually had to disable UAC after finding that no compatibility modes made any difference. That in turn led to some programs no longer finding the correct data that had been saved per-user, although I don't really understand *why* that happened (since I do not run these other programs using the admin as process identity).
SQL Server Management Studio express also refuses to install, and I get messages that warn me "this program has known compatibility issues" so presumably MS is well aware of the problem(s) with it.
Otherwise the dev tools have worked fine and my code works fine, or at least no worse than on other platforms  , although Edit-and-continue is not supported for 64-bit apps - but that was probably the same on XP/Vista in 64-bit editions.

mm.... ok, maybe there are a few compatibility problem after all....
but I managed to swim around them gracefully, so I kind of forget about them!
and I also wonder why there is no edit and continue in 64bit mode?! but ha well, I'm not too miffed, as I still remember the printf debugging experience not so long ago!

The reality is, no software manufacturer has a good record of backward compatibility

i am making text to sign language converter software & want to play continious videos(pre recorded hand movment animations) . the videos are short and many. i used the windows mediaplayer refernce file to play the video files. but the videos dont look continious( gap between 2 videos is no acceptable). so is there any other method to play the files rapidly
tnx in advance

I think Media player stops a certain second before staring another file. This is just because of buffering.
I think you need to create your own player in Flash and use them to avoid this situation...

plz can you be more specific . . .

No, he can't. He's told you exactly what he thinks you need to do. Another solution would be to create playlists in WMP, and if that still gives you a gap, then perhaps you can create two WMP controls and jump between them.

tnx i like the idea of jumping b/n 2 WMPs
|
|
|
|

The player can play from streams, so it must be possible to assemble what to WMP would be one clip dynamically from the parts on the fly. I don't know how difficult this would be to do though.

Hi,
I use the windows apis a lot and often I have to to give a parameter with the DWORD type. From my understanding the equivalent in c# is int... So when I have a parameter like "DWM_TNP_RECTDESTINATION" it's int value is 0x1.
But I only know that since I found an example where they used the code. But now I have another parameter (DWMWA_EXTENDED_FRAME_BOUNDS) from the dwmapi.dll and I don't know how to get the int value since I can't find an example where it is used :S
Isn't there an easier way to get the value instead of finding someone who knows? :P

These values are generally stored in the C/C++ header files associated with the API. So you need to look up the tag in the MSDN documentation and at the bottom of the page there is usually a reference to the associated C++ header file (see this link[^]). Open this file (stored in the SDK directory) to fnd the values. This may mean that you will need to download the Windows SDK from Microsoft.

Google says its 9. Just type the symbol in the search box and read the first 20 excerpts.

You mean, you want to run one application. You can easily do it using Process.Start[^]Process.Start

Hope this part of code can help you.
Process AgentIDEProcess = new Process();
AgentIDEProcess.StartInfo.FileName = "AgentIDE.exe";
string AgentIDEArgument = DirPath + " " + lwSpecFileName + " " + inputFileName + " " + outputFileName;
// CurDir + "
// + sourceId.ToString() + ".xml " + sourceId.ToString() + "input.xml " + sourceId.ToString() + "output.xml";
//AgentIDEArgument = AgentIDEArgument + " " + sourceId.ToString() + "eoptions.xml";
//AgentIDEArgument += " " + sourceId.ToString() + LWFile;
Console.WriteLine("Arguments: " + AgentIDEArgument);
AgentIDEProcess.StartInfo.Arguments = AgentIDEArgument;
AgentIDEProcess.Start();
AgentIDEProcess.WaitForExit();

Hi,
I'm trying to add line index cell to my DataGridView by iterating over the rows.
However, when the list has many rows (hundreds), this loop takes very long time due to CPU consuming.
The "heavy" part is converting the "int" to "String".
The code:
for (int iRowIter = 0; iRowIter < this.Rows.Count; iRowIter++)
this.Rows[iRowIter].Cells[0].Value = iRowIter + 1;
Any suggestions?
Thanks!

IMO, Iterating and putting line number will not be the best option. Try handling RowPostPaint[^] or RowPrePaint event. You will get index of the current row. Using that get the row object and add line number (RowIndex + 1). This will avoid unnecessary iterations on the gridview.
Best wishes,
Navaneeth
