I am trying to use the Windows API GetMonitorInfo but my returned structure seems to always be NULL.  I followed this  ( https://rgagnon.com/pbdetails/powerbuilder-display-on-the-second-monitor.html ) as my starting point but it is not working.  The one odd thing is his example has the structure set with 'rect' as the type but that is not a valid entry so I used 'rectangle'.  I also changed the declarations multiple times but still nothing.  

   function Long MonitorFromWindow (Long hwnd, Long dwFlags) LIBRARY "user32.dll"
   function Long GetMonitorInfo (long hMonitor, ref str_monitorinfo moninfo) LIBRARY "user32.dll" Alias for "GetMonitorInfoW"

Has anyone ever used this?  What I am trying to do is get the monitor handle of the frame so I can determine if this monitor is still valid the next time they launch the application. If it is then I restore the position.

Thanks,

Chris Craft
