如何在Windows7中使用自动鼠标右键单击

本文关键字：鼠标 右键 单击 Windows7 | 更新日期: 2023-09-27 18:20:18

我花了一段时间让我的鼠标能够在Windows XP中右键单击。这是代码：

public class Mouse
{
    [DllImport("user32.dll", SetLastError = true)]
    internal static extern uint SendInput(uint numberOfInputs, Input[] inputs, int sizeOfInputStructure);
    private const int RightDown = 0x0008;
    private const int RightUp = 0x0010;
    private const int InputMouse = 0;
    public void RightClick<T>(T element) where T: AutomationElementWrapper
    {
        var point = element.Element.GetClickablePoint();
        var processId = element.Element.GetCurrentPropertyValue(AutomationElement.ProcessIdProperty);
        var window = AutomationElement.RootElement.FindFirst(
            TreeScope.Children,
            new PropertyCondition(AutomationElement.ProcessIdProperty,
                                  processId));
        window.SetFocus();
         var x = (int)point.X;
         var y = (int)point.Y;
        System.Windows.Forms.Cursor.Position = new System.Drawing.Point(x, y);
        SendInput(2, new[] {InputFor(RightDown, x, y), InputFor(RightUp, x, y)}, Marshal.SizeOf(typeof (Input)));
    }

    private static Input InputFor(uint mouseButtonAction, int x, int y)
    {
        var input = new Input
                        {
                            Dx = x,
                            Dy = y,
                            MouseData = 0,
                            DwFlags = mouseButtonAction,
                            Time = 0,
                            DwType = InputMouse,
                            MouseExtraInfo = new IntPtr()
                        };
        return input;
    }
    internal struct Input
    {
        public int DwType;
        public int Dx;
        public int Dy;
        public uint MouseData;
        public uint DwFlags;
        public uint Time;
        public IntPtr MouseExtraInfo;
    }
}

这在Windows7中不起作用。为什么不呢？我该怎么解决？

有关更多信息，我将在一个自动化工具中使用它来显示上下文菜单。

编辑：@GSerg的链接看起来很有帮助。不过，我不确定一旦添加了并集，输入的"类型"字段中会出现什么——我把它留空了，现在这导致我的屏幕保护程序启动了。啊，Win32的乐趣。感谢您的帮助。

如何在Windows7中使用自动鼠标右键单击

这是我尝试的一个解决方案-这个测试程序结合了开头问题中的代码、pinvoke.net SendInput页面和GSerg链接到的oldnewthing 64位结构对齐解决方案。

有了这个，右键单击在Win7 x64上对我有效：
