windows - 如何使用 Rundll32 来交换鼠标按钮？

Question

我正在重复另一个论坛的问题，因为我想要相同的答案。

来自 MSDN 的 SwapMouseButton Function .

How do I pass boolean data from command prompt through rundll32.exe to a boolean type argument in a command running from user32.dll?

I'm trying to run this from CMD (the command prompt)

RUNDLL32.EXE user32.dll,SwapMouseButton *

Where the asterisk is here is where the argument should go. I already ran it without an argument and it swapped my left and right mouse buttons (seems TRUE is the default entry for the boolean argument). Now I want to undo it. However I've tried each of these for passing FALSE in the argument, and none have worked (none set my mouse buttons back to normal).

• F
• f
• false
• False
• FALSE
• "false"
• "False"
• "FALSE"
• 0
• -1

Please help me pass the argument as needed. Thanks in advance.

非常感谢 C# 解决方案。它就像一个魅力。

我做了一些细微的改动，这样我就可以简单地点击桌面快捷方式来切换主鼠标按钮，而无需传递参数。如果我的方法对其他人有帮助，这里是那个版本:

using System.Runtime.InteropServices;
using System;

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

    static void Main(string[] args)
    {
        int rightButtonIsAlreadyPrimary = SwapMouseButton(1);
        if (rightButtonIsAlreadyPrimary != 0)
        {
            SwapMouseButton(0);  // Make the left mousebutton primary
        }
    }
}
