    Ok, at least I no longer get the Debug Assert, however, my onTimer handler never gets executed. It would appear that the messages are not getting into my class???

    ok, its not a window :)

    It is an object.

    is there a way to cause it to have a window handle, or a way to allow it to receive WM_TIMER messages?

    Re: Timer issue

    Kirants,

    CMotor is derived from CDialog and so should have a valid handle.

    CGDEF,

    When I try to debug, it appears I don't have the source. The assertion occurs in afxwin2.inl line 182.

    Thanks again. I have tried the WM_KEYDOWN message with a similar result to WM_CHAR.... ie nothing.
