Handling Errors During a Method Call

Errors that occur while creating a class instance or during a class method create an exception in the current procedure. 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 are handled this way, including errors within the original MATLAB code. An exception creates a Visual Basic ErrObject object in the current context in a variable called Err. (See the Visual Basic for Applications documentation for a detailed discussion on VBA error handling.) All of the examples in this section illustrate the typical error trapping logic used in function call wrappers for MATLAB Builder EX components.
