Hi, I think a TRY CATCH block is the thing to use. Grep for CTACH and I think you will find a bunch of examples.

However, since it is within an IE where I know the length of the element, I would like to regain control and add an Expert Info and then keep dissecting. How can I handle this? -- Regards, Richard Sharpe (何以解憂?唯有杜康。--曹操)(传说杜康是酒的发明者) ___________________________________________________________________________ Sent via: Wireshark-dev mailing list <wireshark-dev () wireshark org> Archives: https://www.wireshark.org/lists/wireshark-dev Unsubscribe: https://www.wireshark.org/mailman/options/wireshark-dev mailto:wireshark-dev-request () wireshark org?subject=unsubscribe
