If I can use automation to open InfoPath without window?

Detailed infomation,

I want to use automation to open InfoPath and do the next operation, But when I open the InfoPath the InfoPath's main window always shows up.

So my question is if I can set some properties or call some methods to prevent InfoPath main window's showing up.

PS.my office's version is 2k3, and windows' version is windows XP.

Thanks a lot!
