编程鼠标点击在另一个窗口编程鼠标点击在另一个窗口(programmatically mouse cl

是否有可能以编程方式单击另一个窗口的位置不移动鼠标到该位置，甚至如果窗口是不是顶？我想一个样的信息发送到另一个窗口，以模拟上的位置点击鼠标。

我试着用PostMessage的做到这一点：

PostMessage(WindowHandle, 0x201, IntPtr.Zero, CreateLParam(300,300));
PostMessage(WindowHandle, 0x202, IntPtr.Zero, CreateLParam(300,300));

我做了CreateLParam运作是这样的：

private static IntPtr CreateLParam(int LoWord, int HiWord)
{
     return (IntPtr)((HiWord << 16) | (LoWord & 0xffff));
}

问题是，窗口被锁定他的位置。我认为，我的应用程序点击（1,1）的坐标。一些可以帮助我解决这个问题呢？

编辑：这是PostMessage的：

[return: MarshalAs(UnmanagedType.Bool)]
[DllImport("user32.dll")]
public static extern bool PostMessage(IntPtr WindowHandle, int Msg, IntPtr wParam, IntPtr lParam);

和0x201和0x202分别WM_LBUTTONDOWN和WM_LBUTTONUP。

Answer 1:

你可以这样做，通过发送消息，而不是使用SendInput的Windows API。

调用方法ClickOnPoint，这是从形式单击事件的例子，所以this.handle是形式处理，注意，这些都是客户坐标上窗口女巫手柄发送，您可以轻松地改变这一点，送屏幕坐标，而在这种情况下，你不“T需要办理以下ClientToScreen电话。

ClickOnPoint(this.Handle, new Point(375, 340));

更新：现在用SendInput，TNX汤姆。

顺便说一句。我只使用需要此示例的声明，什么更多的有一个很好的图书馆：视窗输入模拟器（C＃SendInput包装-模拟键盘和鼠标）

  public class ClickOnPointTool
  {

    [DllImport("user32.dll")]
    static extern bool ClientToScreen(IntPtr hWnd, ref Point lpPoint);

    [DllImport("user32.dll")]
    internal static extern uint SendInput(uint nInputs, [MarshalAs(UnmanagedType.LPArray), In] INPUT[] pInputs,  int cbSize);

#pragma warning disable 649
    internal struct INPUT
    {
      public UInt32 Type;
      public MOUSEKEYBDHARDWAREINPUT Data;
    }

    [StructLayout(LayoutKind.Explicit)]
    internal struct MOUSEKEYBDHARDWAREINPUT
    {
      [FieldOffset(0)]
      public MOUSEINPUT Mouse;
    }

    internal struct MOUSEINPUT
    {
      public Int32 X;
      public Int32 Y;
      public UInt32 MouseData;
      public UInt32 Flags;
      public UInt32 Time;
      public IntPtr ExtraInfo;
    }

#pragma warning restore 649


    public static void ClickOnPoint(IntPtr wndHandle , Point clientPoint)
    {
      var oldPos = Cursor.Position;

      /// get screen coordinates
      ClientToScreen(wndHandle, ref clientPoint);

      /// set cursor on coords, and press mouse
      Cursor.Position = new Point(clientPoint.X, clientPoint.Y);

      var inputMouseDown = new INPUT();
      inputMouseDown.Type = 0; /// input type mouse
      inputMouseDown.Data.Mouse.Flags = 0x0002; /// left button down

      var inputMouseUp = new INPUT();
      inputMouseUp.Type = 0; /// input type mouse
      inputMouseUp.Data.Mouse.Flags = 0x0004; /// left button up

      var inputs = new INPUT[] { inputMouseDown, inputMouseUp };
      SendInput((uint)inputs.Length, inputs, Marshal.SizeOf(typeof(INPUT)));

      /// return mouse 
      Cursor.Position = oldPos;
    }

  }

我在过去发现，一种方法来发送消息到Windows Media Player，所以我使用的模拟单击应用程序，我想！

使用这个类（代码如下所示）找到窗口，并发送你想要的信息！

using System;
using System.Runtime.InteropServices;

namespace Mouse_Click_Simulator
{
    /// <summary>
    /// Summary description for Win32.
    /// </summary>
    public class Win32
    {
        // The WM_COMMAND message is sent when the user selects a command item from 
        // a menu, when a control sends a notification message to its parent window, 
        // or when an accelerator keystroke is translated.
        public const int WM_KEYDOWN = 0x100;
        public const int WM_KEYUP = 0x101;
        public const int WM_COMMAND = 0x111;
        public const int WM_LBUTTONDOWN = 0x201;
        public const int WM_LBUTTONUP = 0x202;
        public const int WM_LBUTTONDBLCLK = 0x203;
        public const int WM_RBUTTONDOWN = 0x204;
        public const int WM_RBUTTONUP = 0x205;
        public const int WM_RBUTTONDBLCLK = 0x206;

        // The FindWindow function retrieves a handle to the top-level window whose
        // class name and window name match the specified strings.
        // This function does not search child windows.
        // This function does not perform a case-sensitive search.
        [DllImport("User32.dll")]
        public static extern int FindWindow(string strClassName, string strWindowName);

        // The FindWindowEx function retrieves a handle to a window whose class name 
        // and window name match the specified strings.
        // The function searches child windows, beginning with the one following the
        // specified child window.
        // This function does not perform a case-sensitive search.
        [DllImport("User32.dll")]
        public static extern int FindWindowEx(
            int hwndParent, 
            int hwndChildAfter, 
            string strClassName, 
            string strWindowName);


        // The SendMessage function sends the specified message to a window or windows. 
        // It calls the window procedure for the specified window and does not return
        // until the window procedure has processed the message. 
        [DllImport("User32.dll")]
        public static extern Int32 SendMessage(
            int hWnd,               // handle to destination window
            int Msg,                // message
            int wParam,             // first message parameter
            [MarshalAs(UnmanagedType.LPStr)] string lParam); // second message parameter

        [DllImport("User32.dll")]
        public static extern Int32 SendMessage(
            int hWnd,               // handle to destination window
            int Msg,                // message
            int wParam,             // first message parameter
            int lParam);            // second message parameter
    }
}

例如：

 Win32.SendMessage(iHandle, Win32.WM_LBUTTONDOWN, 0x00000001, 0x1E5025B);

下面是我的应用程序源代码，我创建自动点击在“蓝叠”应用程序在一个特定的时间间隔！

对于FindWindow ， wParam ， lParam ，等你可以随意问我该怎么办呢！这不是太硬:);）希望它帮助！ :)
