How to add a bitmap to a Win32 GUI window - user-interface

Question

I am trying to add a bitmap image to a window in my Win32 GUI program.
I watched several tutorials but I couldn't get the image to appear in the window, I compiled the program and it just isn't there.
This is my code, most of it is just the default Codeblocks Win32 template. The image is in the same directory as the files for the program.

Answer 1

The problem was that the image was an invalid file. I opened ms paint and saved the image as a 24bit bitmap and the program worked with no problems.
