CBitmap

[Newbie]

Hello everyone,
i'm new to windows programming in C++. I have to display a 2-D array as
a bitmap. I tried to compile the following code..but the compiler
doesnt identify the CBitmap class...can anyone tell me what is missing
(headers/functions) so as to complete the code??


HDC dc= ::GetDC(0);
int Bps = ::GetDeviceCaps(dc,BITSPIXEL);
::ReleaseDC(0,dc);

int size = 100*100*Bps/8;
BYTE *bbits = new BYTE[size]; //-------------bbits is a 2D(100*100)
array
memset(bbits,192,size);

CBitmap bitmap;
bitmap.CreateBitmap(100, 100, 1, Bps, bbits);

BITMAP bmp;
bitmap.GetBitmap(&bmp);
CClientDC dcScreen(this);
CDC dcMem;
dcMem.CreateCompatibleDC(&dcScreen);
CBitmap *pOld = dcMem.SelectObject(&bitmap);
dcScreen.BitBlt(0,0,bmp.bmWidth,bmp.bmHeight,&dcMem,0,0,SRCCOPY);

dcMem.SelectObject(pOld);
bitmap.DeleteObject();
dcMem.DeleteDC();
delete []bbits;

This group discusses standard C++.

You might find microsoft.public.vc.mfc more useful.

AFAIK, 'CBitmap' is an MFC type, so imo an MFC group
would be the best place to ask, as Victor says.

Note that for types other than the built-in ones (i.e.
those from the standard library or third party libraries
such as MFC, you need to *tell* the compiler about them.
This is done with headers. Find out which header defines
the 'CBitmap' type, and #include it in your code. Again,
any further questions about this should be directed
to an MFC group.
