how to do this in OllyDbg et al?

Hi
I should say I think setting breakpoint in that way is not very efective way.
But if you want to do that,and your program is not packed,use Resource Hacker
to find ID of that item you need.Then set your conditional breakpoint after WndProc
for example WM_LBUTTONDOWN and lparam==ID(as I remember,correct me if wrong).
This will solve your problem.

sincerely yours
