The IpfcXToolkitError exception types provide access to error codes from Creo TOOLKIT functions that the VB API uses internally and to the names of the functions returning such errors. IpfcXToolkitError is the exception you are most likely to encounter because the VB API is built on top of Creo TOOLKIT. The following table lists the IpfcXToolkitError types method and shows the corresponding Creo TOOLKIT constant that indicates the cause of the error.

The exception IpfcXProdevError represents a general error that occurred while executing a Pro/DEVELOP function and is equivalent to an IpfcXToolkitGeneralError exception. (PTC does not recommend the use of Pro/DEVELOP functions.)

The IpfcXExternalDataError exception types and its children are thrown from External Data methods. See the section on External Data for more information.
