Hi!
I'm having problem with the line
cs.lpszClass = AfxRegisterWndClass (CS_NOCLOSE);
in PreCreateWindow function of the MainFrame
I want to disable the "x" (close) button in the upper right corner. That works with the:
cs.lpszClass = AfxRegisterWndClass (CS_NOCLOSE);
But there's a catch, if I use that line my program my applicatin icon (in the upper left corner and when minimized) is replaced by some ugly windows icon!
Is there another way I could do this?

Ok, I'm a beginner at this  so how do I get a handle to an icon in the resource file ?

Hi,
I was wondering if there is any somewhat convenient way of "overriding" the new limitation of SetForegroundWindow() [for Windows 2000] (i.e. that it in fact does not set the window in foreground at all, but merely flashes it.)
I'm developing a small app where it would be nice if it could in fact sit in the background for a while, and then pop up on top of everything else when it's finished. How do I do this now that MS have closed the official door?
It can still be done, as for instance MS own Internet Explorer tends to do this all the time...
Thanks!

This is a short in the dark, have you tried SetActiveWindow after your App finishes working?

You have to implement it like this, in the app(windowhandle) you want to pop to the top:
Sleep(1);
BOOL btemp = SetForegroundWindow( (HWND) windowhandle );
if (!btemp)
{
Sleep(1);
btemp = SetForegroundWindow( (HWND) windowhandle );
}
You need the sleep since the system imposes a min switch time (and the originating app must be finished or at least released it's timeslice). Check the min switch time with:
BOOL bResult = SystemParametersInfo(SPI_GETFOREGROUNDLOCKTIMEOUT,0,timeout,0);

Hi all,
I'm trying to open a video stream but problems arise. Have a look at the code below:
::CoInitialize(NULL);
::AVIFileInit();
PAVISTREAM pAvi;
HRESULT hr = ::AVIStreamOpenFromFile
(&pAvi, "any.avi", streamtypeVIDEO, 0, OF_READ, NULL);
if (SUCCEEDED(hr))
{
AVISTREAMINFO si;
::AVIStreamInfo(pAvi, &si, sizeof(AVISTREAMINFO)); // <- Works ok
IGetFrame *pGetFrame;
pGetFrame = ::AVIStreamGetFrameOpen(pAvi, NULL); // <- Always returns NULL
if (pGetFrame != NULL)
{
pGetFrame->Release();
}
pAvi->Release();
}
::AVIFileExit();
Now, according to msdn, AVIStreamGetFrameOpen() returns NULL if it could not find a decompressor for this specific file. I can however view the file in windows media player w/o any problems. Doesn't that imply I do have a decompressor installed for this file???
I'm confused.  Any help on this would be appreciated.

Hy!
How can I write in the window of a SDI aplication ( derived from CEditView ) from a worker thread??

...the night is long ... but not long enought to do some real coding ...

No, it dosen't because this function return the window caption. Here is what MSDN say :
"Copies the CWnd caption title (if it has one) into the buffer pointed to by lpszStringBuf or into the destination string rString. If the CWnd object is a control, the GetWindowText member function copies the text within the control instead of copying the caption. "

 I know you can ... but in the answer I specified that I want to change it from a worker thred and the function provide by CEditView are not thread-safe ... if you have any idea whow to workaround this problem I will gratly apreciate ...

I've tryed that one to ... but i relly don't want to mdify the MFC source code ... any idea where i can put that critical section ( one is in the worker thread but the ather?? )

Why do you want to modify MFC sources? Just use a critical section to ensure that your threads don't use SetWindowText at the same time.
- add the CCriticalSection member, m_csection, as a private member to CYourEditView
- add new method and use it instead of 'plain' SetWindowText:
void CYourEditView::SafeSetWindowText(LPCTSTR szText)
{
CSingleLock lock(&m_csection, TRUE);
SetWindowText(szText);
}

See CreateFile(). this is a genric function used for opening both files and devices. You can then use WriteFile and ReadFile to talk to it.

Please help me,
I've been trying to solve this problem for more than a week now:
I have to open a textfile with a common dialog box, put this file in a buffer, then I have to show this text in a richeditcontrol by calling the buffer.
Oh, yeah: these text files are at least 1MEG big and I'm just getting started with MFC, glups !
Thanks if you can help me...

Cannot open include file...
Microsoft's products are perfect as always.
What should I do?

mfc42ud.lib is not a header file - it's a library. Anyway, you should set the active configuration to non-unicode before building the sample.

You could use SetText()
or stream the text in with a callback function something like:
DWORD CALLBACK readText(DWORD dwFileHandle, LPBYTE lpBuffer, LONG nbrToRead,
LONG FAR* lpNbrRead)
{
BOOL file = ReadFile((HANDLE)dwFileHandle,lpBuffer, nbrToRead,
(unsigned long*)lpNbrRead, NULL);
if(file == FALSE ){
AfxMessageBox(_T("Could'n open file!"),MB_ICONEXCLAMATION);
return 1;
}
return 0;
}
and then call it with something like this:
EDITSTREAM stream;
HANDLE hFil;
fFormat = SF_TEXT;
strom.dwCookie = (DWORD)hFil;
strom.pfnCallback = readText;
m_recText.StreamIn( fFormat, strom );

OK, I've had a better look at it now.
I still have one question: how do I declare m_readText?
Thanks in advance. Lio.

I want to see only the grid, not a grid in a formview. How do I handle WM_NCPAINT to solve this?
