In C++, the OLE EXCEPINFO structure describes an ActiveX exception. Different ActiveX-enabled IDEs provide different mechanisms for applications to obtain the EXCEPINFO structure contents.
In Visual Basic, exceptions are mapped to the built-in Err object.
The exception number maps to Err.Number and the
description is available as Err.Description. You
can handle exceptions by activating error handling code with the On Error
Goto statement or by checking whether Err.Number is
> 0.
IDL user-defined exceptions are not supported and are mapped to error number 9000.
