how to set button color background and text?

how would i set the background color and text of a pushbutton WITH ONLY API!!!!!!! has to be api becuase i need it for a nother project that isnt vb.

Is it C++? You'll have to subclass your window (change its procedure to your own) and then you'll recieve a WM_CTLCOLORBTN message where you can return the background colour (as HBRUSH) to change the background colour to whatever you want.
BTW, you'll already be handling your window's messages in C++.

asm actully, if youy can give me some vb code to do this i can convert it to asm.

You can try this (did work for me in VB but works in C++):

VB Code:
