Hi All...

I apologize for the lengthy code segment, but I'm not sure what's *NOT*
needed.  I'm having a difficult time (thinking it would be easy) with
SpinButton controls.  My desire is, simply, to have a small string
displayed in a window as the button is changed (in any way).  I cannot seem
to grasp the use of SPBM_QUERYVALUE.  My code will illustrate the method
I'm using now.  Any help will be greatly appreciated.  Here's the code:

    char  szClassName[] = "SpinTest1";
    char  szWindowTitle[] = "Spin Test";

    ULONG flFrameOpts = (FCF_STANDARD &

                        ~FCF_MENU &
                        ~FCF_ACCELTABLE);
