Type: Integer
The errorCode property of the Exception class contains a number that uniquely identifies an exception within a class of exceptions.
As JADE itself uses exception codes with lower numbers (that is, numbers less than 63,999), you should define error codes for your user-defined exceptions in the range 64,000 through Max_Integer (#7FFFFFFF, which equates to 2,147,483,647).
The following examples show the use of the errorCode property.
invalidObjectExceptionHandler(exObj: Exception; referencedObj: Object):
Integer updating, protected;
// -------------------------------------------------------------------------
// Exception handler to reset list box and collection for object not found
// and object deleted exceptions. exObj is the exception object and
// referencedObj is the object to check against the error object.
// -------------------------------------------------------------------------
constants
ObjectNotFound = 4;
ObjectDeleted = 1072;
begin
if (exObj.errorCode = ObjectNotFound or exObj.errorCode = ObjectDeleted)
and
exObj.errorObject = referencedObj
then
// If exception is for the object we're checking for, reset ourselves
abortTransaction;
setCollection(null, false);
return Ex_Abort_Action;
endif;
// Otherwise pass control to the next exception handler
return Ex_Pass_Back;
end;
handleException(exObj: Exception): Integer;
constants
StringTooLong = 1035;
begin
if exObj.errorCode = StringTooLong then
app.msgBox("The picture is too large:", "Error", 0);
return Ex_Abort_Action;
else
return Ex_Pass_Back; // default dialog
endif;
end;
This property is displayed in the default exception dialog as error code. For details, see "Error Messages and System Messages", in the
