Is there a way to save hbitmap to a file?

You typically either create another bitmap using CreateDIBSection, or you get bitmap data with GetDIBits. CreateFile, WriteFile writes data into file. You write: BITMAPFILEHEADER, then BITMAPINFOHEADER, then palette (which you typically don’t have when bits/pixel is over 8), then data itself.

Where do you put the marker in a BMP file?

BMP files have a marker in the first 2 bytes; its “BM”. (Most formats follow this convention somewhat. PNG has the marker “PNG” as the first 3 bytes, for example.) Next, there is the header that you are using (BITMAPFILEHEADER), followed by a BITMAPINFOHEADER, and then the bitmap itself.
