It's atoi [^]:

CString m_s = _T("1949");
int i = _tstoi(m_s);

How to place a Bitmap in the center of a Cdocument document on startup? If tried to find it in codeproject and MSDN but neither shows what I want. I want to place the Bitmap in the center of the document when the program loads(opens). could someone show me code for doing this in MFC? Please.
Thanks in advance. The ID of the Bitmap is IDB_FRACTK.

Look around for a "splash screen" (here or using google...), is that what you mean?

No this is NOT what I'm looking for. I once saw an article that displayed a Bitmap in the CDocument/View interface, but I've lost it somehow. I'll keep hoping someone has one and meanwhile I'll keep looking.

I'm still not sure what you mean but...did you try overwriting the OnPaint method of your view class (or OnDraw maybe?) and do something like this:

CBitmap bitmap;
bitmap.LoadBitmap(IDB_WHATEVER);
CDC MemDC;
MemDC.CreateCompatibleDC(&dc_of_view);
CBitmap *originalBitmap = MemDC.SelectObject(&bitmap);
BITMAP bitmapInfo;
bitmap.GetBitmap(&bitmapInfo);
CRect Rect;
GetClientRect(&Rect)
dc.BitBlt(Rect.CenterPoint().x - bitmapInfo.bmWidth / 2, 
          Rect.CenterPoint().y - bitmapInfo.bmHeight / 2, 
          bitmapInfo.bmWidth, 
          bitmapInfo.bmHeight, 
          &MemDC, 
          0, 
          0, 
          SRCCOPY);
MemDC.SelectObject(originalBitmap);

Yes, that's exactly what I was looking for. Question?: everytime the bitmap gets covered what command do I use to redraw it? (UpdateWindow??)

Once again i am not sure what exactly do you mean but to trigger redrawing of your view you can either use RedrawWindow[^] or InvalidateRect[^] (maybe in conjunction with UpdateWindow right after).

Windows has triggered a breakpoint in Gobang.exe.

This may be due to a corruption of the heap, which indicates a bug in Gobang.exe or any of the DLLs it has loaded.

This may also be due to the user pressing F12 while Gobang.exe has focus.

The output window may have more diagnostic information.

Do any body ever run across problem like this,help me.thanks in advance.

How to pass SendMessage() which is having base class as CWinApp?

Hi all,

I want to use SendMessage(). Through CMainFram class object it works fine but using CWinApp class as base class, it doesn't work. It is not giving any error, but SendMessage() is not called.

I use the following code.

CSampleCMSApp * poApp = (CSampleCMSApp*)AfxGetApp();
SendMessage((HWND)poApp,WM_DISP,0,(long)recv_data);

If i use poApp->SendMessage((HWND)poApp,WM_DISP,0,(long)recv_data);, it give error as
error C2039: 'SendMessageW' : is not a member of 'CSampleCMSApp'.

Can i use SendMessge for the class which is derived from base class as CWinApp?.
If yes, how can i do this.
If no, why i can't?

Please reply.

Thanks,
Abhijit

There are two versions of SendMessage.
One that is global and one that is a member of the CWnd class.

You are getting the error because CWinApp does not directly or indirectly inherit from CWnd, whereas CFrameWnd does inherit from CWnd.

You can use the CWnd member like so

AfxGetMainWnd()->SendMessage(WM_DISP, 0, (LPARAM)recv_data);

You BUY it from a bookshop.
Or maybe the equivalent of amazon.

If you want to steal other people's idea, this is the wrong forum for you.

If you want to buy a downloadable version, I'd encourage you to edit your original question too.
