Whew! What a question! :)

Could you maybe create a global var beforehand, oCode, and in the Init of txtCode, temporarily add: oCode = THIS, and have a breakpoint for oCode.Value. You would get a break at the Init, but just resume.
Sorry, all I can think of.

P.S.: I don't really recommend global vars except for special debugging things like this.
