I would like to make a feature on my program that you can drag a pointer into a Textbox or Combo Box or and object that you can place actual text in.
Most of the time it would be a chat room text box and some kind of instant message textbox. But the idea is that it should work on any application hopefully.

I'm thinking maybe first send text to the object then Get the text from the object to see if it comes back? Maybe that would be an easy way to see if it's a text box like object.. WAIT.. no.. I guess that wouldn't work because you can send text to any window and get it back. :/

Basically it should be like an API Spy but the user wouldn't know anything about that.
This should find the object and then probably save it in a variable. But that's not hard to save it.
I just don't know how to get the handle of any window/object a normal user MouseUps on, and be able to tell if it's a textbox.

Any help?
