I have a bitmap image displayed in my dialog using the picture control and have positioned over the top of it number of CButton's (ie the buttons overlap the image). I want to get the buttons to remain displayed when I change the bitmap image in the button selected function.


Hi! I suggest to make the buttons child controls of the image. They have to be child controls, because overlapping siblings are poorly supported by Windows (see KB79981). Yes the MSDN article is one of the worst I have ever read and left me also confused the first time I read it. Even if you would manage to make overlapping controls work somehow else (e.g. by using transparency), you will sooner or later see redraw artefacts such as parts not been redrawn correctly.

Create your buttons as child controls from the start or use SetParent() in CDesignEditDlg::OnInitDialog().

Let me know if this works for you. Smile | :)
