Thanks for the ideas. Since this app is still in VFP6 I'll experiment with
GetAsyncKeyState.

>Prior to VFP9 all you can do is to call GetAsyncKeyState API:

>#DEFINE VK_SNAPSHOT 0x2c
>
>DECLARE INTEGER GetAsyncKeyState IN user32 INTEGER vKey
>? GetAsyncKeyState(VK_SNAPSHOT)
>

>If PrtScr has been recently pressed, the GetAsyncKeyState returns 1. Though you have to call this function in a cycle or through a timer to react to this event.
>
>There is another API call -- RegisterHotkey -- that can define a system-wide hot key.

>DECLARE INTEGER RegisterHotKey IN user32;
>	INTEGER hWnd, INTEGER id,;
>	INTEGER fsModifiers, INTEGER vk
>

>The first parameter is the handle to a window. That can be either FoxPro form or the main Visual FoxPro window. For example:

>LOCAL hWindow
>hWindow = _Screen.HWnd
>= RegisterHotKey(hWindow, 0, 0, VK_SNAPSHOT)
>* ... somewhere later ...
>= UnregisterHotKey(hWindow, 0)
>

>After the RegisterHotKey returns, this window starts receiving WM_HOTKEY message each time the PrtScr key is pressed. Not much you can get from this fact in VFP8 unless you use some FLLs.

>In VFP9 the BINDEVENT() allows to bind the WM_HOTKEY message to a certain FoxPro code. This technique is described in "Is It Windows or Is It VFP?" article by Drew Speedie published in November 2004 issue of the FoxPro Advisor at http://foxproadvisor.com/doc/14739.
