How do I write this in FASM to receive a handle for a color.

I get a handle for the color BLUE with the code below under MASM, but I get nothing when using FASM.

push 00FFFF00h
call GetSysColor
mov [hBLUE], eax

NOTE: Only black, white and sysBackground color works under FASM with no problems but my own defined colors does not

00000000h black
this work under fasm

1
2
3 etc
also works under FASM

Thanks in advance

There is no such thing as a "handle for a color" in Windows.

The GetSysColor function takes a COLOR_ constant and returns the RGB color value. Since 00FFFF00h is not one of the COLOR_ constants, your call will just return 0.

Thanks Goplat for the info.

Handle may be the wrong word but under MASM all 9 colors I declare (xxxxxxxxh) show 9 dwords under .data? and I can use any of those dword to color what ever is needed. I did that for years. No ColorStatic API needed.

So how do I build my own constants that works for fasm. I tried below but it don't work. It got to be in the style of writing that can works for FASM.

yellow = 0000ffffh

red = 000000ffh

etc

Or is there another way to build color using other means.

Correction. I went blind... I just checked my old code and the thing is to use CreateSolidBrush and save that value.


push COLOR_BACKGROUND
call GetSysColor
mov [hBACKGROUND], eax

push 0080FF00h ; or any color
call CreateSolidBrush
mov [rGREEN]

etc

etc

Thanks for the Wake-Up-Call Goplat
