You're implying that I said I know everything, OR perhaps even, that I have to know everything in order to know what invoking is? :S Explain further, because that logic is flawed the way I'm reading it... And anybody who calls it invoking is wrong. And just further supports what I already know; there's lots of programmers out there, but not all of them are good. So either you misunderstood what these other programmers meant, and you are now using a false interpretation of what you think invoking is, in your posts, or they also don't know what it means.

If you meant, invoking the method in which captures the screen to an image and saves it, then that would be right, but that is the action of the hotkey, and I don't think you understand this...

You don't know what my code was like, so how can you even talk?

I don't have to know what your code looks like in order to tell you that you don't know what invoking is, based on the context by which you use the word in. Your code is irrelevant to my claims. You said you can achieve a global hotkey by invoking the keys:

Use hotkeys and listen for the Prnt Scrn button, you can do this by invoking the keys.

You cannot "listen for the Prnt Scrn button", by "invoking the keys". You can however, invoke the Print Screen key to be pressed, but that's far different than listening for it to be pressed.

You can invoke stuff from a hotkey event, but invoking a hotkey, or a key is poor choice of words that means something entirely different. Look into Virtual Key Events. That would be what "invoking a key" is all about.
