Question: I've developed my forms for a specific screen resolution. How can I determine if my users' displays will handle this??

Answer: The sysInfo() procedure provides two settings that report the screen resoltion. ScreenWdith contains the width of the user's screen and ScreenHeight reports its height. Both value represent the number of pixels involved.

You incorporate this into your application by calling sysInfo() at an appropriate time, probably after the default behavior of the open() event in the first form you diplay in your application.

The following code is a custom method taken from a script designed to report your current screen resolution.

method getScreenRes() recScreenRes
;---------------------------------------------------------------
; Returns the current screen resolution using a custom type
; declared in the Type method.
;---------------------------------------------------------------
var
   rsrCurrent  recScreenRes        ; Current Screen Resolution
   datSysInfo  dynArray[] Anytype  ; Current System Settings
endVar

   sysInfo( datSysInfo )
   rsrCurrent.Width  = datSysInfo[ "ScreenWidth" ]
   rsrCurrent.Height = datSysInfo[ "ScreenHeight" ]
   return rsrCurrent

endMethod

The above method returns its results as a custom record type, declared at the same level as the custom method:

Type
   recScreenRes =
      record
         Width   LongInt
         Height  LongInt
      endRecord
endType

If you wish to adapt this script for your own use, be sure to include the custom method and the Type declaration.
