Forcing FoxPro Window to Always Remain on Top

MORE INFORMATION

The program first declares some compile-time constants (to improve readability) and loads the FOXTOOLS.FLL library that is supplied with FoxPro for Windows. It then retrieves the handle to the main FoxPro window using a call to MainHWND(), which is a function residing in the FOXTOOLS.FLL library. It then calls the SetWindowPos() function and passes the handle to the main FoxPro window and the HWND_TOPMOST constant to make sure that window always remains on top.

   *** Define compile-time constants
   #DEFINE HWND_TOPMOST -1
   #DEFINE HWND_NOTOPMOST -2
   #DEFINE SWP_NOSIZE 1
   #DEFINE SWP_NOMOVE 2

   *** Load FoxTools library
   SET LIBRARY TO SYS(2004)+"FOXTOOLS"

   *** Register the Windows API function
   setwin=RegFn("SetWindowPos","IIIIIII","I")

   *** Obtain handle to main FoxPro window
   handle=mainhwnd()

   *** Call SetWindowPos() API function
   =CallFn(setwin,handle,HWND_TOPMOST,0,0,0,0,SWP_NOMOVE+SWP_NOSIZE)

   *** Release the FoxTools library
   SET LIBRARY TO
				

In order to remove the "always on top" attribute from the main FoxPro window, the program above could be modified to make the CallFn() line use the constant HWND_NOTOPMOST instead of HWND_TOPMOST as the third argument.
