Is it possible to change how the program works?

Question

Software and Internet Services

Briefly about the main thing:
There is a program, when you open it, you need to enter your login, password and click enter, then it hangs in the tray.
Is it possible to do the following (without source codes):
When opening the auto-login using already known login and password + hide from the tray.
Does it make sense to look for information on how to do this or is it completely unrealistic?

Answer 1

AutoIT.
If the program runs fast enough, the user will simply have a window flash.
Absolutely instantly - it will not work.
Although, if your program has a "remember" checkbox, then ...
When you open auto-login using already known login and password + hide from tray.
It is illegal to do such tricks to the user.
But yes, this is possible by sending messages directly to the program window.
How to do illegal things - you can't ask here.
