create CBitmap from buffer

[dima2]

is there a way to create a CBitmap object form a buffer containing
data in bmp format?

Yep,

You can use the CreateBitmapIndirect() to do this. It takes a * to a BITMAP struct that contains the information about the bitmap.

ya, you are going to want to read in the

BITMAPFILEHEADER bmf;
BITMAPINFOHEADER bmi;

and from those you can determine the size of the buffer for the acutal bitmap data

BYTE *bmpBits = new BYTE[bmi.biWidth*bmi.biHeight*bmi.biBitCount/8];

then read the rest of the buffer into that and that is your bitmap bits which the

BITMAP struct will want when you create indirect. Also, other members of BITMAP will need to be set.
