Thank's alot for everyone who gives positive respon about my case and sorry if that distrubing you.

To Gerry,
Why I don't use keyboard is that my program.
Is absentee program that use barcode reader and one mouse that function; left clik for in/out and right clik for choose shift (shift 1,2 and 3) and no keyboard.

So that, if display on monitor show "shift 1" (last using by worker), another worker in shift 3 (for example) have to hit right clik twice more and monitor show "shift 3"

I think it will be more eficient if worker just have to hit one time "roght clik". So I want to use one more mouse in computer (com1) and now the computer have 4 buttons.

Function that 4 buttons is :
Button 1 (left clik mouse 1) for in/out
Button 2 (right clik mouse 1) for shift 1
Button 3 (left clik mouse 2) for shift 2
Button 4 (right clik mouse 2) for shift 3

Re-Question is :
How "Form VFP" can identify that two mouse ?


>Probably, if you use the DirectX DirectInput API; I doubt that it's possible in native VFP (assuming you're still talking about using two mouse(s)).

>>I Just want to use Mouse and activated the Click Event or Right Click Event on form without using the keyboard or else ( If that possible )
