Problem PropertySheets Controls

When using the PropertySheet Control (form comctl32.dll) the program receives a WM_NOTIFY message when the user presses the "Back", "Next", "Finish" or "Cancel" button. The lParam now points to a struct which can be used to get the type of action the user wants. E.g. PSN_WIZFINISH when the user presses "Finish" and PSN_WIZNEXT when the user presses "Next".
When my program receives a PSN_WIZNEXT or PSN_WIZFINISH the program validates the input given by the user.

My problem now is that when the input is invalid the program should stay on the same dialog and so in that case I return -1 (as the MSDN library describes). But... the program still goes to the next dialog (!?).

How do I fix this problem?

Dialog procedures may return TRUE or FALSE only.

To return result to the notification message, use the following code:


    SetWindowLong(hPropPage,DWL_MSGRESULT,-1);
    return TRUE;
