After seeing your hook request here, it occurred to me that the code I suggested in the other thread, viewtopic.php?f=3&t=7396 was not the best solution. You have access to the instance of FormProcEdit and can get and set all controls through the use of FormProcEdit.Controls.Find(). So, passing comboProv.GetSelectedProvNum() and textNotes to the hook method shouldn't be necessary. I think that the following hook would give you access to everything that you need, but I'll wait to hear back from you before implementing anything.
