发送鼠标点击

Question

我试图模拟鼠标点击不使用鼠标通过SendMessage函数 不知它不工作，但没有错误显示。 这里是我的新代码

using System; 
using System.Collections.Generic; 
using System.ComponentModel; 
using System.Data; 
using System.Drawing; 
using System.Linq; 
using System.Text; 
using System.Threading.Tasks; 
using System.Windows.Forms; 
using System.Runtime.InteropServices; 
using System.Windows; 
using System.Windows.Input; 
using System.Diagnostics; 


namespace WindowsFormsApplication1 
{ 
    public partial class Form1 : Form 
    { 
     private const int BM_CLICK = 0x00F5; 

     [DllImport("user32.dll", SetLastError = true)] 
     static extern IntPtr FindWindow(string lpClassName, string lpWindowName); 

     [DllImport("user32.dll", EntryPoint = "FindWindow", SetLastError = true)] 
     static extern IntPtr FindWindowByCaption(IntPtr ZeroOnly, string lpWindowName); 

     [DllImport("user32.dll", CharSet = CharSet.Auto)] 
     static extern IntPtr SendMessage(IntPtr hWnd, UInt32 Msg, IntPtr wParam, IntPtr lParam); 

     [DllImport("user32.dll", SetLastError = true)] 
     public static extern IntPtr FindWindowEx(IntPtr parentHandle, IntPtr childAfter, string className, string windowTitle); 

    public Form1() 
    { 
     InitializeComponent(); 
    } 



     private void button1_Click(object sender, EventArgs e) 
     { 
      IntPtr hwndChild = IntPtr.Zero; 
      IntPtr hwnd = IntPtr.Zero; 
      hwnd = FindWindow(null, "MSPaintApp"); 
      hwndChild = FindWindowEx(hwnd, IntPtr.Zero, "Afx:00007FF765740000:8", null); 
      SendMessage(hwndChild, BM_CLICK, IntPtr.Zero, IntPtr.Zero); 
     } 
    } 
} 

你能不能有人告诉我怎么把X Y协调，这会点击一个子窗口上。我看到很多顶岗怎么做，但我不知道理解和系统说不要在其他人问问题问:(

Answer 1

对我来说，问题是，MSPaintApp窗口应该使用FindWindow("MSPaintApp", null)因为MSPaintApp是类名，而不是窗口的标题进行搜索。

然后，Afx:00007FF765740000:8不是MSPaintApp孩子，但是是MSPaintView的孩子，是孩子MSPaintApp。

你也不必“模拟”一BM_CLICK，但你必须模拟WM_LBUTTONDOWN然后WM_LBUTTONUP

请考虑此示例，似乎工作（在Windows 7）

class Program 
{ 
    private const uint WM_LBUTTONDOWN = 0x201; 
    private const uint WM_LBUTTONUP = 0x202; 
    private const uint MK_LBUTTON = 0x0001; 

    public delegate bool EnumWindowsProc(IntPtr hWnd, IntPtr parameter); 

    [DllImport("user32.dll", SetLastError = true)] 
    static extern IntPtr FindWindow(string lpClassName, string lpWindowName); 

    [DllImport("user32.dll", CharSet = CharSet.Auto)] 
    static extern IntPtr SendMessage(IntPtr hWnd, UInt32 Msg, IntPtr wParam, IntPtr lParam); 

    [DllImport("user32.dll", SetLastError = true)] 
    public static extern IntPtr FindWindowEx(IntPtr parentHandle, IntPtr childAfter, string className, string windowTitle); 

    [DllImport("user32.dll", SetLastError = true)] 
    public static extern bool EnumChildWindows(IntPtr hwndParent, EnumWindowsProc lpEnumFunc, IntPtr lParam); 

    static IntPtr childWindow; 

    static void Main(string[] args) 
    {      
     IntPtr hwndMain = FindWindow("MSPaintApp", null); 
     IntPtr hwndView = FindWindowEx(hwndMain, IntPtr.Zero, "MSPaintView", null); 
     // Getting the child windows of MSPaintView because it seems that the class name of the child isn't constant 
     EnumChildWindows(hwndView, new EnumWindowsProc(EnumWindow), IntPtr.Zero); 
     // Simulate press of left mouse button on coordinates 10, 10 
     SendMessage(childWindow, WM_LBUTTONDOWN, new IntPtr(MK_LBUTTON), CreateLParam(10, 10)); 
     // Simulate release of left mouse button on coordinates 100, 100 
     SendMessage(childWindow, WM_LBUTTONUP, new IntPtr(MK_LBUTTON), CreateLParam(100, 100)); 
    } 

    static bool EnumWindow(IntPtr handle, IntPtr pointer) 
    { 
     // Get the first child because it seems that MSPaintView has only this child 
     childWindow = handle; 
     // Stop enumerating the windows 
     return false; 
    } 

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

我在这里可以追溯到很多年，但我敢肯定鼠标事件窗口消息不会在应用程序最小化时传递，我敢肯定最小化窗口的处理方式不同，无论如何，

不管这个代码在窗口没有最小化的时候工作吗？你可能想用Spy ++来查看在窗口的结构中，我认为你需要获得你想要点击的任何东西的hWnd，并在那里发送消息，这很大程度上取决于应用程序本身是如何编写的以及如何绘制UI。
