【CSharp】 WIN服务实现窗体

使用方法要注意的是安装服务后设置服务让可以与用户交互。


	///使用方法

	protected override void OnStart(string[] args)
	 {
	 Thread _TestForm = new Thread(new ThreadStart(StartListen));
	 _TestForm.Start();
	 }
	 public void StartListen()
	 {
	
	 Zgke.WindowFrom.Service.ServerWindows.ServiceForm(EventLog);
	 System.Windows.Forms.Form _MyForm = new System.Windows.Forms.Form();
	 _MyForm.Text = "打开窗体 Application";
	
	
	 System.Windows.Forms.Application.Run(_MyForm);
	 while (true)
	 {
	 Thread.Sleep(100000);
	 }
	 }

	

	下面是全部类

	using System;
	using System.Collections.Generic;
	using System.Text;
	using System.Runtime.InteropServices;
	namespace Zgke.WindowFrom.Service
	{
	 /// <summary>
	 /// WINDOWS SERVER 开启窗体
	 /// zgke@sina.com
	 /// qq:116149
	 /// </summary>
	 public class ServerWindows
	 {
	
	 /// <summary>
	 /// 开启窗体 使用后用 System.Windows.Forms.Application.Run(_Form);来启动窗体
	 /// </summary>
	 /// <param name="s">日志</param>
	 public static void ServiceForm(System.Diagnostics.EventLog p_ServiceLog)
	 {
	 try
	 {
	 GetDesktopWindow();
	 IntPtr _WindowsStation = GetProcessWindowStation();
	 IntPtr _ThreadID = GetCurrentThreadId();
	 IntPtr _DeskTop = GetThreadDesktop(_ThreadID);
	 IntPtr _HwinstaUser = OpenWindowStation("WinSta0", false, 33554432);
	 if (_HwinstaUser == IntPtr.Zero)
	 {
	 RpcRevertToSelf();
	 return;
	 }
	 SetProcessWindowStation(_HwinstaUser);
	 IntPtr _HdeskUser = OpenDesktop("Default", 0, false, 33554432);
	 RpcRevertToSelf();
	 if (_HdeskUser == IntPtr.Zero)
	 {
	 SetProcessWindowStation(_WindowsStation);
	 CloseWindowStation(_HwinstaUser);
	 return;
	 }
	 SetThreadDesktop(_HdeskUser);
	 IntPtr _GuiThreadId = _ThreadID;
	 _GuiThreadId = IntPtr.Zero;
	 SetThreadDesktop(_DeskTop);
	 SetProcessWindowStation(_WindowsStation);
	 CloseDesktop(_HdeskUser);
	 CloseWindowStation(_HwinstaUser);
	 }
	 catch (Exception ex)
	 {
	 p_ServiceLog.WriteEntry(ex.ToString());
	 }
	 }
