Remarks

This event fires anytime the component receives a message, be it an indication or a success/error response.

The Method parameter reflects the method of message received.

• 1 (BINDING)
• 2 (SHARED_SECRET)
• 3 (ALLOCATE)
• 4 (REFRESH)
• 6 (SEND)
• 7 (DATA)
• 8 (CREATEPERMISSION)
• 9 (CHANNELBIND)

The Indication parameter indicates whether the message is an indication (versus a success/error response).

The TransactionId parameter reflect's the message's transaction Id.

If the message is an error response, the ErrorCode and ErrorMessage will reflect the error information returned by the server; otherwise they will be 0 and empty string, respectively.
