It seems that you want to have a running application, and be able
to do things with it from within another application, while the
original application keeps on running at the same time.
A mechanism for this is usually called IPC - short for InterProcess
Communication. You have to create some sort of interface in
your application that allows it to be accessed "from the outside",
whatever that may be (you called it "loggin into an application").
It could also very well be that you just want to "look inside"
your running application. Debuggers are the tools for doing that.
