Hi Fabio,
Thre're some other keys and key combinations that produce the same codes in Visual FoxPro. You can use Windows API function GetKeyState in such cases. See Re: Is there a way to detect a Key being help down? Message #633669.
Thanks Sergey, I thought to use just this.
But since it is VFP that consume the buffer, the result is a bad way to program
( program output is function of input speed and application speed ).
We suppose of having a PC with 99.99% CPU used from an other process,
could be that what gives back GetkeyState to me is not corrected.
