Question:
How do I check the value of QRExpr control at runtime?


Answer:
The Value property of a TQRExpr component is of type 
TQREvResult. You can check Value.Kind to see what the 
data type is. The following table shows how to retrieve the 
results of the expression based on the value of Value.Kind:

  Value.Kind   The result is in
   resInt       Value.IntResult
   resDouble    Value.DblResult
   resString    Value.StrResult
   resBool      Value.BooResult
   resError    there was an error

The constants are defined in the QRPrntr unit.
