Keypress detection

[icywind]

Hi all,

Is there a way for autoit to detect a certain key(let's say "a"), to know whether its pressed(held down) ?

I need to make a function that executes certain command if its held down and otherwise.

[Jabberwock]

make a hotkey for it,

HotKeySet("{a}", "hotkey_1")

Func hotkey_1()

your command here

EndFunc

or IsPressed

To elaborate on MSLx Fanboy's suggestion

$keys = StringSplit("ABCDEFGHIJKLMNOPQRSTUVWXYZ", "")
$dll = DllOpen('user32.dll')
While 1
    Sleep(250)
    If _IsPressed("23", $dll) Then
        MsgBox(0, "_IsPressed", "End Key Pressed")
        ExitLoop
    EndIf
    For $x = 1 To $keys[0]
        If _IsPressed(Hex(Asc($keys[$x]),2)) Then
            MsgBox(0, "key pressed", $keys[$x])
        EndIf
    Next
WEnd
DllClose($dll)


Func _IsPressed($s_hexKey, $v_dll = 'user32.dll')
; $hexKey must be the value of one of the keys.
; _Is_Pressed will return 0 if the key is not pressed, 1 if it is.
    Local $a_R = DllCall($v_dll, "int", "GetAsyncKeyState", "int", '0x' & $s_hexKey)
    If Not @error And BitAND($a_R[0], 0x8000) = 0x8000 Then Return 1
    Return 0
EndFunc  ;==>_IsPressed
