使用C#在另一个应用程序上执行鼠标Click事件

标签: c# mouseevent simulate

我需要做的是我需要使用自定义应用程序控制安装在同一台机器上的另一个应用程序。例如,如果我需要使用标准的Windows计算器,我只需将输入事件发送到计算器。我已经使用了一些代码片段来实现这一点,现在我已经触发了鼠标和键盘事件。但问题是我可以确定键盘事件会触及目标应用程序,因为它有进程句柄。但我不能确定鼠标。如果目标应用程序进入后台,我也无法启动鼠标点击。我需要帮助才能找到确保鼠标单击仅在应用程序上完成的方法。

我需要发送鼠标坐标并点击。例如" sendMouseClick("Notepad", 100, 400);,它会向记事本发送一个点击,即使它保持最小化。

*************** ****** 重要的提示****************************************** *********** 之前回答过类似的问题,但是参考首先找到另一个应用程序的状态,然后用键盘或鼠标发送输入,我需要做的是向应用程序发送一组必须工作的指令在前景与否。 对于"其他伙伴" ::如果你不想帮助或无法帮助,那没关系,但请知道我没有偷这个问题或任何东西。我只是想在C#中完成这个任务。

我必须模拟键盘按键的代码按:

using System;
using System.Diagnostics;
using System.Runtime.InteropServices;
using System.Drawing;
using System.Windows.Forms;

namespace SimulateKeyPress
{
    partial class Form1 : Form
{
    private Button button1 = new Button();
    private Button button2 = new Button();
    private Button button3 = new Button();

    [STAThread]
    public static void Main()
    {
        Application.EnableVisualStyles();
        Application.Run(new Form1());
    }

    public Form1()
    {
        button1.Location = new Point(10, 10);
        button1.TabIndex = 1;
        button1.Text = "Click to automate Calculator";
        button1.AutoSize = true;
        button1.Click += new EventHandler(button1_Click);

        button2.Location = new Point(150, 140);
        button2.TabIndex = 0;
        button2.Text = "Click to Exit Calculator";
        button2.AutoSize = true;

        button2.Location = new Point(80, 80);
        button2.TabIndex = 2;
        button2.Text = "Click to Run Calculator";
        button2.AutoSize = true;

        button2.Click += new EventHandler(button2_Click);
        this.DoubleClick += new EventHandler(Form1_DoubleClick);

        this.Controls.Add(button1);
        this.Controls.Add(button2);
       // this.Controls.Add(button3);
    }

    // Get a handle to an application window.
    [DllImport("USER32.DLL", CharSet = CharSet.Unicode)]
    public static extern IntPtr FindWindow(string lpClassName,
        string lpWindowName);

    // Activate an application window.
    [DllImport("USER32.DLL")]
    public static extern bool SetForegroundWindow(IntPtr hWnd);

    // Send a series of key presses to the Calculator application. 
    private void button1_Click(object sender, EventArgs e)
    {
        // Get a handle to the Calculator application. The window class 
        // and window name were obtained using the Spy++ tool.
        IntPtr calculatorHandle = FindWindow("CalcFrame", "Calculator");


        //Process firstProc = new Process();
        //firstProc.StartInfo.FileName = "calc.exe";
        //firstProc.EnableRaisingEvents = true;

        //firstProc.Start();

        // Verify that Calculator is a running process. 
        if (calculatorHandle == IntPtr.Zero)
        {
            MessageBox.Show("Calculator is not running.");   
            return;
        }

        // Make Calculator the foreground application and send it  
        // a set of calculations.
        SetForegroundWindow(calculatorHandle);
        SendKeys.SendWait("1024");
        SendKeys.SendWait("*");
        SendKeys.SendWait("32");
        SendKeys.SendWait("=");
    }
    private void button2_Click(object sender, EventArgs e)
    {
        System.Diagnostics.Process.Start("calc.exe");

    }
    private void button3_Click(object sender,EventArgs e) 
    {
        Process [] proc =Process.GetProcessesByName("Calculator");
        proc[0].Kill();
    }
    // Send a key to the button when the user double-clicks anywhere  
    // on the form. 
    private void Form1_DoubleClick(object sender, EventArgs e)
    {
        // Send the enter key to the button, which raises the click  
        // event for the button. This works because the tab stop of  
        // the button is 0.
        SendKeys.Send("{ENTER}");
    }
}
}

以前的堆栈溢出帮助,msdn和其他站点提供了在同一个应用程序中模拟鼠标单击的代码。但我需要将鼠标命中发送到另一个应用程序。

也许这可以帮到你

代码

任务

  • 获取鼠标的当前位置
  • 发送鼠标事件

Windows窗体

...
using System.Runtime.InteropServices;

namespace yournamespace
{

 public partial class yourclassname
 {
[DllImport("user32.dll", CharSet = CharSet.Auto, CallingConvention = CallingConvention.StdCall)]
    public static extern void mouse_event(uint dwFlags, uint dx, uint dy, uint cButtons, uint dwExtraInfo);

    private const int MOUSEEVENTF_LEFTDOWN = 0x02;
    private const int MOUSEEVENTF_LEFTUP = 0x04;
    private const int MOUSEEVENTF_RIGHTDOWN = 0x08;
    private const int MOUSEEVENTF_RIGHTUP = 0x10;

    int X = Cursor.Position.X;
    int Y = Cursor.Position.Y;
    mouse_event(MOUSEEVENTF_LEFTDOWN | MOUSEEVENTF_LEFTUP, X, Y, 0, 0);
  }
}   

WPF

WPF中的事情有点困难

double mousePointX;
double mousePointY;
[DllImport("user32.dll")]
[return: MarshalAs(UnmanagedType.Bool)]
static extern bool GetCursorPos(out POINT lpPoint);

[StructLayout(LayoutKind.Sequential)]
public struct POINT
{
  public int X;
  public int Y;

  public POINT(int x, int y)
  {
      this.X = x;
      this.Y = y;
  }
}

private void WritePoint(object sender, RoutedEventArgs e)
{
    POINT p;
    if (GetCursorPos(out p))
    {
        System.Console.WriteLine(Convert.ToString(p.X) + ";" + Convert.ToString(p.Y));
    }
}
[DllImport("User32.dll")]
static extern IntPtr GetDC(IntPtr hwnd);

[DllImport("gdi32.dll")]
static extern int GetDeviceCaps(IntPtr hdc, int nIndex);

[DllImport("user32.dll")]
static extern bool ReleaseDC(IntPtr hWnd, IntPtr hDC);

private Point ConvertPixelsToUnits(int x, int y)
{
    // get the system DPI
    IntPtr dDC = GetDC(IntPtr.Zero); // Get desktop DC
    int dpi = GetDeviceCaps(dDC, 88);
    bool rv = ReleaseDC(IntPtr.Zero, dDC);

    // WPF's physical unit size is calculated by taking the 
    // "Device-Independant Unit Size" (always 1/96)
    // and scaling it by the system DPI
    double physicalUnitSize = (1d / 96d) * (double)dpi;
    Point wpfUnits = new Point(physicalUnitSize * (double)x,
    physicalUnitSize * (double)y);

    return wpfUnits;          
}
private void WriteMouseCoordinatesInWPFUnits()
{
    POINT p;
    if (GetCursorPos(out p))
    {
    Point wpfPoint = ConvertPixelsToUnits(p.X, p.Y);
    System.Console.WriteLine(Convert.ToString(wpfPoint.X) + ";" +   Convert.ToString(wpfPoint.Y));

    mousePointY = wpfPoint.Y;
    mousePointX = wpfPoint.X
    }
}

现在是代码中最重要的部分

 [DllImport("user32.dll", CharSet = CharSet.Auto, CallingConvention = CallingConvention.StdCall)]
    public static extern void mouse_event(uint dwFlags, uint dx, uint dy, uint cButtons, uint dwExtraInfo);

    private const int MOUSEEVENTF_LEFTDOWN = 0x02;
    private const int MOUSEEVENTF_LEFTUP = 0x04;
    private const int MOUSEEVENTF_RIGHTDOWN = 0x08;
    private const int MOUSEEVENTF_RIGHTUP = 0x10;

    ...    
        mouse_event(MOUSEEVENTF_LEFTDOWN | MOUSEEVENTF_LEFTUP,   Convert.ToUInt32(mousePointX), Convert.ToUInt32(mousePointY), 0, 0); 
    ...

警告

  • 代码经过测试
  • 代码不是"副本&粘贴代码
