    background of dialogbox transparent.. why?

    Hi, im having a problem with the background of a dialogbox from a resource script.

    Those Control windows appear on the screen as they should, but the background window don't. Why is this happening?



    Code:

    Try removing the WS_EX_TRANSPARENT style from your controls.

    If you need a control to be 'transparent' then adjust the z-order so the higher 'level' controls are drawn on top (or give these controls the TOPMOST style) or use ShowWindow() to hide it.

    Other than that post the callback as this can be a paint / erase background issue.
