Question

我想查看进程列表以确定OpenOffice Calc是否正在运行或者OpenOffice Writer是否正在运行。关闭QuickStart后，我会得到一个scalc.exe和一个swriter.exe，所以很简单。

然而，当快速启动时，我只能获得soffice.bin和soffice.exe

有没有办法询问这些进程正在运行哪个应用程序？

我认为没有办法检查窗口标题。您必须枚举所有窗口并检查标题是否以“ - OpenOffice.org Writer”或“ - OpenOffice.org Calc”等结尾。

以下简短示例将检查Writer是否正在运行：

using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.Runtime.InteropServices;
using System.Text;

namespace Sample
{
    public class Window
    {
        public string Title { get; set; }
        public int Handle { get; set; }
        public string ProcessName { get; set; }
    }

    public class WindowHelper
    {
        /// <summary>
        /// Win32 API Imports
        /// </summary>
        [DllImport("user32.dll")]
        private static extern int GetWindowText(IntPtr hWnd, StringBuilder title, int size);
        [DllImport("user32.dll")]
        private static extern int EnumWindows(EnumWindowsProc ewp, int lParam);
        [DllImport("user32.dll")]
        private static extern bool IsWindowVisible(IntPtr hWnd);
        [DllImport("user32.dll", SetLastError = true)]
        static extern uint GetWindowThreadProcessId(IntPtr hWnd, out uint lpdwProcessId);

        public delegate bool EnumWindowsProc(IntPtr hWnd, int lParam);

        private List<Window> _openOfficeWindows;

        public List<Window> GetOpenOfficeWindows()
        {
            _openOfficeWindows = new List<Window>();
            EnumWindowsProc ewp = new EnumWindowsProc(EvalWindow);
            EnumWindows(ewp, 0);

            return _openOfficeWindows;
        }

        private bool EvalWindow(IntPtr hWnd, int lParam)
        {
            if (!IsWindowVisible(hWnd))
                return (true);

            uint lpdwProcessId;
            StringBuilder title = new StringBuilder(256);

            GetWindowThreadProcessId(hWnd, out lpdwProcessId);
            GetWindowText(hWnd, title, 256);

            Process p = Process.GetProcessById((int)lpdwProcessId);
            if (p != null && p.ProcessName.ToLower().Contains("soffice"))
            {
                _openOfficeWindows.Add(new Window() { Title = title.ToString(), Handle = hWnd.ToInt32(), ProcessName = p.ProcessName });
            }

            return (true);
        }
    }
    class Program
    {
        static void Main(string[] args)
        {
            WindowHelper helper = new WindowHelper();

            List<Window> openOfficeWindows = helper.GetOpenOfficeWindows();

            foreach (var item in openOfficeWindows)
            {
                if (item.Title.EndsWith("- OpenOffice.org Writer"))
                {
                    Console.WriteLine("Writer is running");
                }
            }
        }
    }
}

如何判断openoffice的哪个应用程序正在运行？
