I would like to be able to see/set break points on certain conditions for wlm but i'm not sure how with olly although i've herd you can. I know i can view them with Spy++ but i'd like to trace them.

You can set a conditional breakpoint (Shift+F2). A quick google search should give you some information about the conditions

what should i set it on though? SendMessageW and PostMessage? or is there any way i can set it on the message handler?

You can either set it on SendMessage/PostMessage (which will filter the message for all windows) or set it on the message handler (which will filter for only specific windows).

To find the message handler for a window, open Spy++ (not at the same time as OllyDbg or you'll get a system hang ) and locate the window you'd like to watch. Then look in the properties, and the address of the message handler function will be shown. The condition will be something like:

code:

[EBP+8] == ___

thank you
