Dialog Button Color

I am unable to get the background color of a dialog button to match that of the dialog. I am using the following code:

invoke GetDlgItem, hWnd, IDC_ABOUTCLOSE
            mov    hButtonClose, eax
            invoke SetWindowPos, hButtonClose, 0, 253, 220, 70, 20, NULL
            invoke SendMessage,  hButtonClose, WM_SETFONT, hAboutFont, NULL
            invoke SetProp, hButtonClose, ADDR FGRND, 0
            RGB 185, 185, 185
            mov    BtnColor, eax
            invoke SetProp, hButtonClose, ADDR BGRND, addr BtnColor
            invoke GetProp, hButtonClose, ADDR BBRUSH
            mov hBrush, eax
            RGB 185, 185, 185
            invoke CreateSolidBrush, eax            
            invoke SetProp, hButtonClose, ADDR BBRUSH, addr BtnColor
            .if hBrush
                  invoke DeleteObject, hBrush
            invoke InvalidateRect, hButtonClose, NULL,TRUE

I have tried everything I can think of, or I find on the net.

actually, i never seen assembly code for dialog handling before ... what is the advantage? even windows is using c and winapi ....

nevertheless, i would assume, that the above coding wouldn't work in c or mfc either. i think the InvalidateRect to the button window will not cause any painting action since the dialog is responsible for painting its children.

you either could try to calculate the rectangle where the button was located relative to the dialog client window and invoke InvalidateRect for the dialog window using passing the address of the rectangle as argument, or, you hide/show the button. both actions might cause the button to be redrawn. if the color nevertheless was not changing, i would try again but not deleting the brush created.

The solution is much simpler than what I was trying. Use a bitmap button.
