how to remap keyboard?

gabriel · Post by **gabriel** » Tue Apr 12, 2011 8:37 pm

hello:
is it possible to remap some keys of keyboard, for example, on my french layout keyboard, I like to remap the "£" to "<", and "µ" to ">".
the program should be resident and active for all subsequent windows applications.
Thanks

You should be able to do it a level with a low level keyboard hook
I'll post an example.

Try something like KeyTweak (free):

replaces A->S Z->X
but if you have mappings like A->Z and Z->A you will need to ignore the next keyevent or it'll switch it back to what it was

Code: Select all

#WH_KEYBOARD_LL = 13
#INPUT_HARDWARE = 2
#INPUT_KEYBOARD = 1
#KEYEVENTF_UNICODE = $4
#KEYEVENTF_SCANCODE = $8


Global myKeyHook

Structure KBDLLHOOKSTRUCT
 vkCode.l;
 scanCode.l;
 flags.l;
 time.l;
 dwExtraInfo.l;
EndStructure

Structure INPUT_DATA
type.l
  StructureUnion
     mi.MOUSEINPUT
     ki.KEYBDINPUT
     hi.HARDWAREINPUT
  EndStructureUnion
EndStructure

Procedure.l KeyProc(nCode.l,wParam.l,lParam.l)

    Protected *keyInput.KBDLLHOOKSTRUCT 
    Protected ret.l, hwnd.l
    Protected mkeyInput.KEYBDINPUT
    Protected InputData.INPUT_DATA
    
    Inputdata\type = #INPUT_KEYBOARD   
    *keyInput = lParam
   
    If nCode = #HC_ACTION 
      
      If *keyInput\vkCode =#VK_A
          inputdata\ki\wVk= #VK_S 
          
      ElseIf *keyInput\vkCode =#VK_Z
          inputdata\ki\wVk= #VK_X     
          
      EndIf 
      If inputdata\ki\wVk <> 0  
        
        inputdata\ki\wScan = 0
        inputdata\ki\time = *keyInput\time
        InputData\ki\dwExtraInfo = *keyInput\dwExtraInfo     
               
        If wParam = #WM_KEYUP
           InputData\ki\dwFlags = #KEYEVENTF_SCANCODE | #KEYEVENTF_KEYUP   
        EndIf
          
         SendInput_(1,InputData, SizeOf(INPUT_DATA))
           
          result =1   
       Else 
          result= CallNextHookEx_(myKeyhook, nCode, wParam, lParam)  
       EndIf
        
    Else
      result = CallNextHookEx_(myKeyhook, nCode, wParam, lParam)
    EndIf
 
    ProcedureReturn result
             
EndProcedure 

Procedure SetHook()
    hInstance = GetModuleHandle_(0)
    If hInstance 
       myKeyhook = SetWindowsHookEx_(#WH_KEYBOARD_LL, @KeyProc(),hInstance,0) 
    Else 
       MessageRequester("hook", "can't get module handle")
    EndIf       
EndProcedure 

Procedure KillHook()

   UnhookWindowsHookEx_(myKeyhook)
   myKeyHook = 0 
  
EndProcedure 


sethook()

OpenWindow(0,0,0,200,200,"test")

Repeat 
  ev=WaitWindowEvent()
Until ev= #PB_Event_CloseWindow 

killhook()

Hi Idle, I got the impression that Gabriel is actually just looking for a one-off re-map for his own keyboard. That can be done in the registry if we are talking Windows, which is what KeyTweak does in a User friendly way..........

Didn't know you could do that through the registry?

Thank you guys:
The situation is the following:
on my french layout keyboard, i don't have the "<" and ">" keys, I use for thar alt+60 and alt+62.
In the same time, I use very rarely "£" and "µ", so I thought may be it's possible to remap £ and µ to < and >.
I tried SharpKeys and similar, they want the virtual key number #VK_etc... I searched in the PB constants, I didn't find any virtual key for them.
The problem is that "£" is shift+"$", and "µ" is shift+"*", (the attached picture may help), so we need to bypass the shift

May be there is no solution for that.

edit: how to insert a picture??

Did you try KeyTweak?

To insert an image, you need to upload the image to an image host (such as your own website), then use the Img button here to insert the URL to the image.

KeyTweak, like others (SharpKeys, KeyExtender, etc...), accept only english keyboard layout, also the characters £,µ,<,> don't figure in the list of available keys.
Apparently, I should resign

Hi:
thanks RASHAD:
I tried your code and changed slightly, it works, except I don't know the VK number for "<" (on a french layout keyboard)

Use the next code with all your keyboard keys with Shift or Ctrl
till you get Less-Than"<" and Greater-Than">" and give us what you got

Code: Select all

OpenWindow(0, 0, 0,300,40, "", #PB_Window_MinimizeGadget|#PB_Window_ScreenCentered)
TextGadget(0, 0, 8, 300, 20, "Press any key.", #PB_Text_Center)

Repeat
  Event = WaitWindowEvent()
  
  If Event = #WM_CHAR
    key = EventwParam()
    Debug Str(KEY) + "    " + Chr(key)
    SetGadgetText(0, Str(KEY) + "    " + Chr(key))
    
  EndIf
  
Until Event = #PB_Event_CloseWindow

As per idle suggest and what I prefer to end the program(From inside the loop)
