OmfProgressHandler()

 Called by MaxOmfSdk to drive a progress meter dialog

 OmfProgressHandler() is a place-holder for the an application

 defined callback function passed to MaxOmfSdk through the

 MxOmfAppIFInfo_t struct. See MxOmfAppIFInfo_t

 See OmfSupp.cpp of the MaxOmfSdk demo application for a

 working example for Win32/MFC. This drives an MFC dialog class -

 See OmfPgDlg.h and OmfPgDlg.cpp for the progress dialog

 implementation. This may be used unchanged.

 Params:

     void* vpProgressDlg - void pointer to application supplied progress meter

     int start - If > zero, sets number to increment (steps) if zero, increments (steps)

     TCHAR* opName - Unicode string for 1st item of progress meter (operation Name)

     TCHAR* statLine1 - Unicode string for 2nd item of progress meter

     TCHAR* statLine2 - Unicode string for 3rd item of progress meter

     BOOL userCanCancel - Command flag - progress and operation cancel allowed

     BOOL* cancel - Flag - if userCanCancel is TRUE, when *cancel goes TRUE, abort

 Returns:

   The value of of the increment count

 Usage:

   See OmfSup.cpp OmfProgressHandler()

extern int OmfProgressHandler(void* vpProgressDlg,

              int start,

              TCHAR* opName,

              TCHAR* statLine1,

              TCHAR* statLine2,

              BOOL userCanCancel,

              BOOL* cancel);
