Can someone please help me? I want to get a Bitmap to be displayed on a DC (Plain windows not DirectX or any thing). I got a bitmap in a resource file: IDB_BITMAP and a the handle of a DC: hDC. Can some please tell what functions in what order are needed to load the bitmap and draw it on the DC; Thanks in advance.

LoadBitmap to get the bitmap into a HBITMAP if its a resource bitmap. Then use CBitmap::Atach() to attach the handle to the class CBitmap:
theBitmap.Attach(theHandle); 

Create a memory DC and initialize it:
CDC memDC;
memDC.CreateCompatibleDC(&hDC);


Then, select the CBitmap into the context:
memDC.SelectObject((CBitmap *)theBitmap); // Not sure if you need the cast or not 


Then, draw it by blitting:
hDC.BitBlt(0,0,bitmapwidth, bitmapheight, &memDC, 0, 0, SRCCOPY); 


And CHABOOM, there it is, on the context (usally pDC in OnDraw).
