hiding process icon to run in background - vb.net

Question

I have a programs path..like utorrent and it pid too. I have achieved these values programatically using vb.net. I just want to hide their icon form tray just to run them in background and if possible attach the process with a hotkey to call them back. Is there any way to achieve this.

To hide your form -> form1.visible=false
To hide your form from taskbar -> form1.ShowinTaskbar=false
then go to the form1 keydown event and put this...
If e.Control And e.KeyCode = Keys.Q Then ' ---> activate with Ctrl-Q
form1.visible=true
End If
