Alright well ive been trying to figure out how to do this for a long time and I've searched around and I guess I have alot of questions but I'll explain my problem first.

Ok First off I have vb6.0 and im somewhat familar with how to get handles on programs and such but I am making a program and I want to add in AIM functions sort of, such as like when I click a button on my form, it opens aim, and types in my password and signs me in. I also want to know how to send text to other programs ive gone to yahoo and google and searched the postmessage and sendmessage api functions or whatever and i just cant seem to grasp what i need to do. I want to be able to output text from a text box, into other programs , but without using anything like sendkeys or key_bd input or whatever, cant i use postmessage to post the message to a certain field or something once it has focus?
