Hola.
Estoy tratando de hacer algo que invierta los ejes del raton.
osea que si voy a la derecha la flechita valla a la izquierda y etc.

Tengo el codigo Choreado Prestado del NRC de Psyke con hook al mouse pero ni idea como hacer

 puedo tomar la poscicion actual del cursor y hacerlo saltar a una.

osea, los comandos los tengo, me falta cabeza de programador.

Gracias por la ayuda.

Codigo del hook al mouse

Option Explicit
 
Private Declare Function SetWindowsHookEx Lib "user32.dll" Alias "SetWindowsHookExA" (ByVal idHook As Long, ByVal lpfn As Long, ByVal hmod As Long, ByVal dwThreadId As Long) As Long
Private Declare Function UnhookWindowsHookEx Lib "user32.dll" (ByVal hHook As Long) As Long
 
Dim hHook As Long
 
Public Sub StartHook()
    hHook = SetWindowsHookEx(14, AddressOf MouseProc, App.hInstance, 0)
End Sub
 
Public Sub StopHook()
    Call UnhookWindowsHookEx(hHook)
End Sub
 
Private Function MouseProc(ByVal nCode As Long, ByVal wParam As Long, lParam As Long) As Long
    'On Error Resume Next
    If wParam = 516 Then 'si sirve de algo el wParam cuando se mueve el mouse es 512
      Form1.Print "CLICK BOTON DERECHO"
    ElseIf wParam = 517 Then Form1.Print "SOLTÓ BOTON DERECHO"
    ElseIf wParam = 513 Then Form1.Print "CLICK BOTON IZQUIERDO"
    ElseIf wParam = 514 Then Form1.Print "SOLTÓ BOTON IZQUIERDO"
    ElseIf wParam = 519 Then Form1.Print "CLICK BOTON MEDIO"
    ElseIf wParam = 520 Then Form1.Print "SOLTÓ BOTON MEDIO"
    End If
 
    Form1.Caption = wParam
End Function

Este es el codigo de pruebas que tengo en el form.

Option Explicit
Private Declare Function GetCursorPos Lib "user32.dll" (ByRef lpPoint As POINTAPI) As Long
Private Declare Function SetCursorPos Lib "User32" (ByVal X As Long, ByVal Y As Long) As Long
 
'\\Variables
Private Type POINTAPI
    X As Long
    Y As Long
End Type
 
Dim pt As POINTAPI
Dim Que As Variant
Dim cX As Integer, cY As Integer
Private Sub Command1_Click()
   GetCursorPos pt
   cX = pt.X: cY = pt.Y
   Command1.Caption = cX & ";" & cY
End Sub
 
Private Sub Form_Load()
  Me.AutoRedraw = True
  StartHook
End Sub
Private Sub Form_Unload(Cancel As Integer)
  StopHook
End Sub

Cuando apretas el boton Command1 cambia su caption a las coordenadas del cursor
Para hacer "saltar" el cursor es

SetCursorPos [X,Y]

.
Si no me equivoco debes modificar la estructurea lParam (En este hook, en este parametro de ddevuelve una estructura), despues de hacer eso pasa el mensaje normalmente!¡.

El lParam tiene las coordenadas de X del cursor.

pero sigo sin entender
no se como hacer

Funsionaria si hago que cuando se mueva el mouse cursor valla a la diferencia entre el lPram actual y el antiguo menos el ancho total de la pantalla?

Mira esto :

        End If
    End If
    MouseProc = CallNextHookEx(m_HookProc, nCode, wParam, lParam)

,,,mmm Algo asi mas o menos desia yo xP...

Creo que anda un poco mal no lo probe, asi que alrato lo checo bien, aun asi lo dejo.
