How to Stop a Form from Loading

MORE INFORMATION

You can stop a form from loading if a variable or expression evaluates to false (.F.). For example, if you want to load an inquiry form based on a table called Students only if the table has records, place the following code in the Init event of the form:

   IF RECCOUNT("students")==0
      =messagebox("No students have been entered",64,"Student table empty")
      RETURN .F.
   ENDIF
				

The Load event occurs, but the form is never instantiated.
