如何移动第二个打开的浏览器窗口？

Question

我正在尝试制作一个在每个多显示器上打开浏览器的程序。 当我用记事本做的时候，它起作用了。但是，当它是浏览器不工作并显示错误“System.InvalidOperationException：进程必须退出才能确定请求的信息”时。感谢您对这种情况的帮助。

这是我的代码：

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;

namespace WindowsFormsApp5
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        [System.Runtime.InteropServices.DllImport("user32.dll")]
        private static extern int MoveWindow(IntPtr hwnd, int x, int y,
    int nWidth, int nHeight, int bRepaint);

        private void Form1_Load(object sender, EventArgs e)
        {

            foreach (Screen item in Screen.AllScreens)
            {
                //Open a web browser
                System.Diagnostics.Process process1 = System.Diagnostics.Process.Start("C:\\Program Files (x86)\\Microsoft\\Edge\\Application\\msedge.exe");
                //System.Diagnostics.Process process2 = System.Diagnostics.Process.Start("notepad.exe");
                process1.WaitForInputIdle();
                //process2.WaitForInputIdle();

                //Move the browser window
                MoveWindow(process1.MainWindowHandle, item.Bounds.X, item.Bounds.Y, item.Bounds.Width, item.Bounds.Height, 1);
                //MoveWindow(process2.MainWindowHandle, item.Bounds.X, item.Bounds.Y, item.Bounds.Width, item.Bounds.Height, 1);

            }
        }
    }
}

好像msedge.exe使用了一个宿主进程来启动不同的标签页，所以我们不能使用创建的进程ID来处理它。

将创建的进程 ID 与任务管理器中的进程进行比较，即 进程38756 丢失。

另一个浏览edge相关进程的工具是edge的内置任务管理器。

我们也找不到进程38756。

所以需要重新搜索目标edge进程。

这个 repo https://github.com/alex-tomin/Tomin.Tools.KioskMode 演示了如何将 chrome 窗口移动到不同的显示器并设置为全屏。

我尝试提取必要的并修改您的代码，如下所示，希望对您有所帮助：

            process.Start();
            process.WaitForInputIdle();
        }

        private IntPtr GetWindowHandle(string processName, List<IntPtr> ignoreHandlers)
        {
            IntPtr? windowHandle = null;
            while (windowHandle == null)
            {
                windowHandle = Process.GetProcesses()
                    .FirstOrDefault(process => process.ProcessName == processName
                        && process.MainWindowHandle != IntPtr.Zero
                        && !string.IsNullOrWhiteSpace(process.MainWindowTitle)
                        && !ignoreHandlers.Contains(process.MainWindowHandle))
                    ?.MainWindowHandle;
            }

            return windowHandle.Value;

    }
