Swapping left and right mouse button in .NET

Question

How do I swap left and right mouse buttons in .NET (preferably C#)? Basically the result should be the same as if the user checked the \"Switch primary and secondary buttons

Answer 1

Here's a code snippet that does this.

Answer 2

Something like this:

using Microsoft.Win32;

var key = Registry.CurrentUser.CreateSubKey("Control Panel\\Mouse\\");
var newValue = key.GetValue("SwapMouseButtons");

if (newValue == null) newValue = "1";
else                  newValue = Int32.Parse(newValue) == 1 ? "0" : "1";

key.SetValue("SwapMouseButtons", newValue, RegistryValueKind.String);

Answer 3

You can use a Windows API call to SwapMouseButton:

using System.Runtime.InteropServices;

// ...

[DllImport("user32.dll")]
public static extern Int32 SwapMouseButton(Int32 bSwap);

// ...

// Swap it.
SwapMouseButton(1); 

// Back to normal.
SwapMouseButton(0);
