Remapping the Mousewheel to a keyboard key with autoit

Tag: key , autoit , remap Author: yy20092 Date: 2012-02-11

i want to remap the mouseup and mouse down to keys on my keyboard only while using a certain application. This is how far i got on my own:

_WinWaitActivate("League of Legends (TM) Client","")
HotKeySet("{K}", "WinTab")

Func WinTab()

#region --- Internal functions Au3Recorder Start ---
Func _WinWaitActivate($title,$text,$timeout=0)
    If Not WinActive($title,$text) Then WinActivate($title,$text)
#endregion --- Internal functions Au3Recorder End ---

This would remap the letter k to the letter g. It should be possible to remap the MouseWheel as well, but i could not find the approbriate keybinding. Another thing is, i want to pause the remapping if {Esc} is pressed or Alt-Tab or another letter is pressed.

cheers and thanks

    While True
   If IsPressed('21') Then 
         MouseWheel("up", 2)

   If IsPressed('22') Then 
         MouseWheel("down", 2)

Func IsPressed($hexKey)   
   Local $aR, $bO
   $hexKey = '0x' & $hexKey
   $aR = DllCall("user32", "int", "GetAsyncKeyState", "int", $hexKey)
   If Not @error And BitAND($aR[0], 0x8000) = 0x8000 Then
      $bO = 1
      $bO = 0
   Return $bO
EndFunc  ;==>_IsPressed

Other Answer1

You cannot bind mouse actions using HotKeySet, as that is only for keyboards.

Instead there are several options:

The second part has been done thousands of times... Search for it :)


Is the answer of @ADIN right? What is the role of the Func IsPressed($hexKey) on his answer?
@Servant, Yes, he is just using my first suggestion from this answer. He is also defining IsPressed himself rather than using the one included in the AutoIt Misc.au3 standard UDF.
But I think he did not disable the original functions of mouse scroll wheel.
