Перехват событий мыши с помощью глобальной ловушки. Остановить действие

Question

Я пытаюсь перехватить и прервать события мыши. Допустим, я хотел отключить событие нажатия правой кнопки мыши или даже событие перемещения мыши. Я не смог разобраться с прерывающей частью.

Я использую (я предполагаю, довольно широко используемый) следующий код для Global Hooking мыши.

Private Structure MSLLHOOKSTRUCT
    Public pt As Point
    Public mouseData As Int32
    Public flags As Int32
    Public time As Int32
    Public extra As IntPtr
End Structure

Private _mouseHook As IntPtr
Private Const WH_MOUSE_LL As Int32 = 14

Private Delegate Function MouseHookDelegate(ByVal nCode As Int32, ByVal wParam As IntPtr, ByRef lParam As MSLLHOOKSTRUCT) As Int32
<MarshalAs(UnmanagedType.FunctionPtr)> Private _mouseProc As MouseHookDelegate
Private Declare Function SetWindowsHookExW Lib "user32.dll" (ByVal idHook As Int32, ByVal HookProc As MouseHookDelegate, ByVal hInstance As IntPtr, ByVal wParam As Int32) As IntPtr
Private Declare Function UnhookWindowsHookEx Lib "user32.dll" (ByVal hook As IntPtr) As Boolean
Private Declare Function CallNextHookEx Lib "user32.dll" (ByVal idHook As Int32, ByVal nCode As Int32, ByVal wParam As IntPtr, ByRef lParam As MSLLHOOKSTRUCT) As Int32
Private Declare Function GetCurrentThreadId Lib "kernel32.dll" () As Integer
Private Declare Function GetModuleHandleW Lib "kernel32.dll" (ByVal fakezero As IntPtr) As IntPtr


Public Function HookMouse() As Boolean
    Debug.Print("Mouse Hooked")
    If _mouseHook = IntPtr.Zero Then
        _mouseProc = New MouseHookDelegate(AddressOf MouseHookProc)
        _mouseHook = SetWindowsHookExW(WH_MOUSE_LL, _mouseProc, GetModuleHandleW(IntPtr.Zero), 0)
    End If
    Return _mouseHook <> IntPtr.Zero
End Function

Public Sub UnHookMouse()
    Debug.Print("Mouse UnHooked")
    If _mouseHook = IntPtr.Zero Then Return
    UnhookWindowsHookEx(_mouseHook)
    _mouseHook = IntPtr.Zero
End Sub

Private Function MouseHookProc(ByVal nCode As Int32, ByVal wParam As IntPtr, ByRef lParam As MSLLHOOKSTRUCT) As Int32
    'Debug.Print("Message = {0}, x={1}, y={2}", wParam.ToInt32, lParam.pt.X, lParam.pt.Y)
    If wParam.ToInt32 = 513 Then
        '''interrupt the left mouse button event here, but don't know what to return to do so.
    End If
    Return CallNextHookEx(WH_MOUSE_LL, nCode, wParam, lParam)
End Function
