Creating A Hotkey Which Perform A Button Click In The Form?

I am currently developing a small capture system program. What I intend to do is to create a hot key for my program to capture image (press F8 then it will invoke a button to click automatically). What I manage to do for the time being is only registerHotkey procedure. (Please refer to the coding below). I am unable to create a hot key which perform like a button click.

This is just a testing program: I have 2 forms specifically. Form1 with a button and form2 with a picture box.

I would like to run this program where I can just simply click F8(for instance) instead of clicking the button.

For the time being I am able to run this program and put it in the system tray when I minimize/closed it. When I click F9 the program will pop up again. What I would like to do now, is clicking F8 (for instance and the program able to click a button from form 1 automatically). I had used PerformClick but still unable to do so.
