Handling Errors During a Method Call

If your application generates an error while creating a class instance or during a class method call, the current procedure creates an exception.

Microsoft Visual Basic provides an exception handling capability through the On Error Goto <label> statement, in which the program execution jumps to <label> when an error occurs. (<label> must be located in the same procedure as the On Error Goto statement.) All errors in Visual Basic are handled this way, including errors within the MATLAB code that you have encapsulated into a COM object. An exception creates a Visual Basic ErrObject object in the current context in a variable called Err.

See the Microsoft Visual Basic documentation for a detailed discussion on Visual Basic Basic error handling.
