There's an article here[^] which might be of help.

Nope. This doesn't help since it's not actually starting a drag operation on an item, but on a selection rectangle.

But your issue is handling the mouse move messages not starting the operation isn't it?

Hi everyone,
I want to complie a program but I get this error
"fatal error C1083: Cannot open include file: 'atlapp.h': No such file or directory"
then I download WTL7.0 and I set path of wtl on Tools->Options->Projects->VC++ directories in the end of list I insert C:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\PlatformSDK\wtl70\include
but again I get same error.
Can you help me
Thanks

What is "atlapp.h" and from where does this file come from ? You need to put this file in your project directory or in one of the include directories.
|

You didn't say which list you changed in the VC++ Directories page. Make sure you changed the include path.

Hi Michael
I saw your article about this problem and you have a link for download wtl on your article I didnt changed any thing I insert it line to(on the enviroment VC++ on the menu Tools->Options->Projects->VC++ directories
we have a list of paths I insert this line C:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\PlatformSDK\wtl70\include to it
but I dont know why it doesnt solve
Thanks

On the VC++ Directories page, you can change one of several lists (include path, lib path, and so on). Make sure you're changing the include path.

Thank you Michael

I have been using Visual Studio .NET 2003 Professional on Win XP (SP2) for development of simple dialog based programs in VC++ using MFC.
For last few days I have some problems with the debugging of my programs. When I debug any program without any break points, it runs well. Same is the case when I run the program without debugging (Ctrl+F5). When I put some break points in it there is no activity for a long time (I have waited even for half an hour! ). Probably the machine hangs. I cannot even kill the process (using Task Manager) because Ctrl+Alt+Del does not work.
I have repaired the installation once which yielded no improvement. Then reinstalled Studio .NET without any success.
Can anybody suggest some solution to this problem please?
Thanks .

This may be a dumb question, but are you using F10 to move on to the next line, or F11 to step into the next line?
Also where are you putting the break point? is it around a loop? if this is the case, you may have to move through the break point many times (until all iterations have completed.
what happens when you hit F5 once the break point is hit?

I do not need to use F10 o F11 since I put a break point at some code and start it using F5. Before the cursor come to the break point the machine hangs. I want to know whether any dll file has been corrupt causing the the problem. Otherwise I am quite experienced with debugging.

Whoa, Whoa, Whoa, calm down buddy,
I'm not familiar with your level of experience. If the program runs fine with out the break point, then the DLL files should be fine. Any other information you can give us?

I used to have this exact same problem with VC6. Sometimes the breakpoint would hit, sometimes not. But more often than not it would appear the code had an infinite loop, even though it did not. I never did solve the problem and later started using VC8. I have no debugging problems now.

Stab in the dark...maybe an IntelliSense issue...
Try
1) Close Visual Studio.
2) In your solution folder, rename "solutionname.ncb" to "solutionname_bak.ncb" where solutionname
is the name of the solution containg the project you are debugging.
3) Open the solution
4) Rebuild the project
5) Try to debug the project again

Hi all,
I need to know if a modeless dialog is opened and,
if this is the case, close it.

Look up IsWindow() and IsWindowVisible().
You may be right

Use FindWindow()

You can use of
HWND hWnd = ::FindWindow("Notepad", NULL);
or CWnd *pWnd = ::FindWindow("Notepad",NULL);

Can anybody please tell me why the following code runtime errors at ar.close()?
CFile SaveColours;
SaveColours.Open("Colours.def",CFile::modeWrite);
CArchive ar(&SaveColours,CArchive::store);
int i=0;
while (i++<=20)
ar << i;
ar.Close();// <-----Runtime error as invalid file handle
SaveColours.Close();
Any references much appreciated.

Have you run this under the debugger? That's usually a good start. You can step into the CArchive::Close function and find out why it trips up.
You should also check that the Open for SaveColours worked properly.
(You might want to use CFile::modeCreate | CFile::modeWrite instead of just CFile::modeWrite, as well).
Chances are that because CArchive uses a buffer (around 4K) it isn't actually doing any I/O until you call Close, at which point it flushes (or tries to) to file.
