Hi Evan,

Thanks for your help.

I tried to do this, and perhaps I just got it (slightly) wrong.

In my foo_dissect() function, I looked up the conversation, grabbed the latest sequence number, incremented it, and wrote it back to the conversation.  I displayed it in the tree_item for the PDU, and in the COL_INFO, which was basically what I was after.

The issues I had seemed to be related to when my dissection function was called: if I scrolled from start to end of the capture, it was fine.  If I jumped to the final frame, the sequence number wasn't incremented for the intervening PDUs.

Perhaps I need it to be done outside my  if (tree) { ... } ?

Thanks again; any suggestions appreciated,



d
