Don't know if this is documented somwhere but this sounds like Screen Saver attempt at getting the focus before actually going in Screen Saver mode.

This is actually what you get when you click on the desktop and drag a rectangle. So, to answer your previous post, it isn't some sort of screensaver... but something is taking the focus away from the desktop. I will keep on looking.

I think you're getting focus and mouse capture confused. They are not the same thing. To check for a focus change, you'll need to handle WM_KILLFOCUS, not WM_CAPTURECHANGED.
Hope this helps,

Sorry, you are right. I believe what is going on is that upon the user clicking and dragging inside the window, WM_CAPTURECHANGED is received indicating that the mouse capture has been released (that's probably what lParam=0 means).
The problem, then, is that WM_MOUSEMOVE messages are being posted on the event-queue but my WindowProc never receives them. I am subclassing some other window. My guess is that the window calls GetMessage(), sees WM_MOUSEMOVE, and handles it internally without passing it on to the WindowProc. This poses a problem for me because I absolutely must subclass WM_MOUSEMOVE. Any ideas?

That would be my guess as well. One way to get around this is to install a WH_GETMESSAGE hook, which will get called whenever a message is retrieved from the message queue.

Hi everyone.
I am using Visual Studio, visual C++ 7.0 and having problem adding an event handler to a button in controlbar.
I used the editor to add abutton, gave it an ID but I could not not find ways to add a function for that button. I was able to do that in version 6.0.
Please help.

I was browsing the board to see if anyone had found a solution to this problem, and came across your post. I imagine you have found a way round this by now, but I thought I would reply anyway:
I can't believe that the designers meant to make the task of connecting an event handler to a button more difficult than it used to be. I assume it was an unintended side effect of trying to produce the unified .NET programming interface (which regretably seems to have involved discarding MFC's ClassWizard) - but what continues to puzzle me is that this has not been subject to a patch or improvement in later releases.
I don't have an anwer, but I do have a workaround. Build a MENU item first, attach the handlers you want to it, then build a toolbar button with the same ID (and it will share the same event handlers).
If you right click on menu items and select the "add event handler" option, the Event Handler Wizard appears and gives you the option to create or edit handlers for COMMAND and UPDATE_COMMAND_UI messages.
The rule seems to be, right click on the thing you want to create a handler for and the Event Handler Wizard will provide pretty much the same functionality as MFC's ClassWizard - except that it doesn't work for toolbar buttons because right clicking doesn't give you the option - seems nuts to me!
Please let me know if you have found a better way in the meantime.
Best Regards
Cliff

hi
I wrote a service in which i want to pass some parameters from INI file but when i give the path as .\\TibcoTCPServer.ini it does not work but if i hard code the path it works fine. Can any body help me how can i pass the ini file path so that service will pick the parameters.
Thanks
Shailesh

.\\TibcoTCPServer.ini is a relative path, which means it's relative to whatever happens to be the current working directory at the moment. Use GetModuleFileName(NULL, ...) instead to get the application's fully-qualified path, then replace the filename with TibcoTCPServer.ini.

if i use GetModuleFinename(NULL..) I Get the Memory could not be read error. My Code is as
BOOL FillParams()
{
CFileFind fileFinder;
CIniReader m_IniFile;
TCHAR Buffer[BUFSIZE];
DWORD dwRet,nSize;
CString error;
dwRet = GetModuleFileName(NULL,Buffer,nSize);
if( dwRet == 0 )
{
error.Format("Failed GetCurrentDirectory %d",GetLastError());
WriteToLog((LPSTR)(LPCTSTR)error);
return 0;
}
WriteToLog(Buffer);
// Here i am changing the path..
}
But It is failing at GetModuleFineName function or crashing.
Any Suggestion..
Thanks
Shailesh

You've failed to inform the function of the size of the buffer.

I am using
#define BUFSIZE MAX_PATH

|

I did not indicate that the buffer itself was not large enough. Check your code again. Note the third parameter being passed to GetModuleFileName().

I'm trying to use AnimateWindow() in my dialog's InitDialog() handler as I've seen in a few other places, but I keep getting compiler errors if I try to call the global api (::AnimateWindow(hWnd,200,AW_SLIDE), or without the scope resolution operator, or even as a member of my CDialog-derived class. I also tried an example I found on the MSDN where I use FARPROC and load the function from user32.dll and it tells me that I'm supplying too many parameters for a pointer to function (even though I just cut and paste the code right out of the MSDN). Any help would be greatly appreciated.

When I try to use it globally, I get these:
g:\My Projects\CPlusPlus\VC.NET\Bug Reporter\Bug Reporter\ChatDlg.cpp(60): error C2039: 'AnimateWindow' : is not a member of 'operator``global namespace'''
g:\My Projects\CPlusPlus\VC.NET\Bug Reporter\Bug Reporter\ChatDlg.cpp(60): error C2065: 'AW_SLIDE' : undeclared identifier
g:\My Projects\CPlusPlus\VC.NET\Bug Reporter\Bug Reporter\ChatDlg.cpp(60): error C3861: 'AnimateWindow': identifier not found, even with argument-dependent lookup
And when I try to use it as a member function of CDialog-derived class, I get these:
g:\My Projects\CPlusPlus\VC.NET\Bug Reporter\Bug Reporter\ChatDlg.cpp(60): error C2039: 'AnimateWindow' : is not a member of 'CChatDlg'
g:\My Projects\CPlusPlus\VC.NET\Bug Reporter\Bug Reporter\ChatDlg.cpp(60): error C2065: 'AW_SLIDE' : undeclared identifier

I found another example here on CP in which the author says that you need to do this:
#undef WINVER
#define WINVER 1000000
I did that and now it works!! thanks

I've never heard of that version of Windows!

Me either, but I guess it's just to say that you have access to everything, since I think I've seen in some places it'll check WINVER in certain places (#if WINVER > 0x400)

So you don't get slammed later on, I would go into the header file that contains the prototype for AnimateWindow() and see what value of WINVER it is looking for. Most likely it's 0x0500.
