Geeko,
The WM_PAINT message doesn' paint the background, WM_ERASEBKGND does, cach that, and paint you background there.
Umbongo
but with what function, and why doesnt superclassing workx anyway? 10x for answer
As I just learned the other day, the WM_CTLCOLORSTATIC message is sent as a control is preparing to draw it's background. Intercept this message and you can change the color to that of your choice.
In my case, I had a dialog window with a read-only edit control, which unalterably defaults to a gray background. So I stuck the following message handler in the dialog proc to change this:
.ELSEIF uMsg == WM_CTLCOLORSTATIC
invoke GetDlgItem,hWnd,IDC_EDIT
.IF eax == lParam
invoke GetStockObject, WHITE_BRUSH
ret
.ELSE
mov eax, 1
ret
.ENDIF
Ernie: a read-only edit control acts like a static control: that's why Windows sends WM_CTLCOLORSTATIC message to the control when it needs to repaint the control. However, for normal edit control, you must intercept WM_CTLCOLOREDIT message instead.
Very thank you for reply, but i am wondering anyway why superclassing doesnt work. i superclass hrbBackground appropriate and it just doesnt go...if i change wndproc, cursor it works very well,
bye
