Errors are captured differently in Cicode and VBA. The following code examples show how to trap and handle errors in VBA and Cicode.
[VBA]
Sub VBATest(myObject As Object)
On Error Goto errHandler
myObject.<function>
Exit Sub
errHandler:
Print Err.Number, Err.Description
Resume Next
End Sub
[Cicode]
FUNCTION Test1(OBJECT hObject)
ErrSet(1); // Enable User error checking (disabled HW alarm)
IF ObjectIsValid(hObject) THEN
_ObjectCallMethod(hObject, "<function>");
error = IsError();
errorMessage = IntToStr(error)
IF (error <> 0) THEN
Message("An error occured", errorMessage, 0);
END
END
ErrSet(0); // Enable hardware alarm reporting of errors
END
