Message Handling

Alright, I need to write an app that when a window pops up with a specific title bar, the app will automatically click one of the two buttons (like a yes/no msgbox) I have know idea how to even go about this, so I'm asking for any assistance anyone would be willing to give.. Just a question, no pay (sorry..) ## Deliverables 1) Just a question I'm hoping someone can answer. I'm not picky about rights or ownership, I just need a bit of help. ## Platform Windows XP
