This example uses the default dialog procedure for the file dialog to cause default processing of unprocessed dialog messages.

#define INCL_WINSTDFILE  /* Window Standard File Functions       */
#include <os2.h>

MRESULT MyFileDlgProc(HWND  hwnd, ULONG  msg, MPARAM mpParam1,
                      MPARAM mpParam2)
{
switch(msg)
   {

   /**************************************************************/
   /* Process user-supported messages                            */
   /**************************************************************/
   .
   .
   .
   default:
      return (WinDefFileDlgProc(hwnd, msg, mpParam1, mpParam2));
   }
}
