ClickHeRe, yes, this is the way I have tried before - and am still trying to bring it to work. The SendMessage(hWnd_toolbar, TB_ADDIMAGE, ...) call returns a SUCCESS code (the index of the first newly added image), but when I assign this image to my button, the button remains blank.
You say people have done this before me? Can you give me an example (because the above thing doesn't really work)? (I know that MDX is not doing exactly what I want...)
I still need your help.
