How to find and disable the call to window closing func using OllyDebug debugger ?

Hi all .There is an .exe application that has window on it and it closes when some coditions become true. I wonder if there is a ways to find and disable that close window function? could you guys tell me steps that i need to follow in order to trace that closing function and disable it?Looking forward for replies.Thanks

well, yes its quite easy actually, u would have to open the api tab in olly to see what api's the programs using and you could put break points on all api's witch create windows (witch you will look for in the api help manual). Honestly for a complete video tutorial go here

those tutorials will explain slightly better what you need. After all reversing is very fun if you know what ure doing in assembly and stuff :P

what you can do is set a break on DestroyWindow, then check your call stack.
