BitBlt returns an error if the source and destination device contexts represent different devices. To transfer data between device contexts for different devices, convert the memory bitmap to a DIB by calling GetDIBits. To display the DIB to the second device, call SetDIBits or StretchDIBits.

The BitBlt function can be used to quickly render a Bitmap onto a Control (and much, much more). For this purpose, it is much faster than the managed alternative, Graphics.DrawImage(). See the example code below.

BITMAPINFO

The BITMAPINFO structure defines the dimensions and color information for a DIB, it contains the members

BITMAPINFOHEADER structure (contains information about the dimensions of color format) and bmiColors which contains one of the following:

See MSDN Documentation for BITMAPINFO concerning specific details concerning structure members.

hSection is a handle to a file mapping object that the function will use to create the DIB and can be NULL. If hSection is not NULL, it must be a handle to a file mapping object created by calling the CreateFileMapping function (otherwise CreateDIBSection will fail). Moreover, the CreateDIBSection function will locate the bitmap’s bit values at offset dwOffset in the file mapping object referred to by hSection. An application can retrieve the hSection handle by calling the GetObject function with the HBITMAP returned by CreateDIBSection.

dwOffset specifies the offset from the beginning of the file mapping object referenced by hSection where storage for the bitmap’s bit values is to begin (ignored if hSection is NULL). The bitmap’s bit values are aligned on doubleword boundaries, so dwOffset must be a multiple of the size of a DWORD.

If the function succeeds, the return value is a handle to the newly created device-independent bitmap (and ppvBits will point to the bitmap’s bit values). If the function fails, the return value is NULL (and ptr ppvBits will be NULL). To get extended error information, call GetLastError.
