wwUtils::SafeEval

Evaluates a FoxPro expression without blowing up by wrapping the EVALUATE() operation into an internal TRY/CATCH block.

o.SafeEval(lcEvalString,lvErrorResult)

lcEvalString
String to evaluate - same value you would pass to EVALUATE()

lvErrorDisplay
The value to return when an error occurs Pass the special value** ERRORMESSAGE** to return the error message

You cannot pass expressions that contain local variables or the THIS pointer since they will not be in scope in the executing wrapper function.

<>*** Execute 2 + 2 on Error -1 would be returned lnResult = SafeEval("2+2",-1)


*** return the error message in lnResult
lnResult = SafeEval("2+2+A","ERRORMESSAGE")

IF VARTYPE(lnResult) = "C" ? lnResult && Error Message ENDIF <>
