Is it possible automation possible without using automation tool? This question is running in my mind so long time. The question just like what is base behind the automation tool or foundation of the automation tool.
Re: Is automation possible without automation tool
I think that all automation tools use Windows API to get access to all objects (windows and their controls) and to send commands to the objects.
I've used Windows API to identify a window that was not visible, but was existed as a process, and then to kill the window.
Look for Windows API reference at MSDN.
