Function Reference

_WinAPI_GetKeyState

Retrieves the status of the specified virtual key

#include <WinAPISys.au3>
_WinAPI_GetKeyState ( $vKey )

Parameters

$vKey

Specifies a virtual key ($VK_*). If the desired virtual key is a letter or digit (A through Z,
a through z, or 0 through 9).

Return Value

Returns the value that specifies the status of the specified virtual key. If the high-order bit is 1, the key is
    down; otherwise, it is up. If the low-order bit is 1, the key is toggled. A key, such as the
    CAPS LOCK key, is toggled if it is turned on. The key is off and untoggled if the low-order bit is 0.
    A toggle key's indicator light (if any) on the keyboard will be on when the key is toggled, and off
    when the key is untoggled.

Remarks

The key status returned from this function changes as a process reads key messages from its message queue.
The status does not reflect the interrupt-level state associated with the hardware. Use the _WinAPI_GetAsyncKeyState()
function to retrieve that information.

_WinAPI_GetAsyncKeyState

Example

#include <WinAPISys.au3>
#include <WinAPIvkeysConstants.au3>

Local $aOnOff[2] = ['OFF', 'ON']

ConsoleWrite('NumLock: ' & $aOnOff[BitAND(_WinAPI_GetKeyState($VK_NUMLOCK), 1)] & @CRLF)
Sleep(1500)
Send('{NUMLOCK toggle}')
ConsoleWrite('NumLock: ' & $aOnOff[BitAND(_WinAPI_GetKeyState($VK_NUMLOCK), 1)] & @CRLF)
Sleep(1500)
Send('{NUMLOCK toggle}')
ConsoleWrite('NumLock: ' & $aOnOff[BitAND(_WinAPI_GetKeyState($VK_NUMLOCK), 1)] & @CRLF)
