Web page Launch WinForm program

The requirements for this article are:

A. Launch the WinForm program through A Web page;

B. Pass the parameters of the page to the WinForm program;

The C.winform program has started and is running when the WinForm program cannot be restarted from the Web page.

Only when the parameters of the incoming WinForm program change, the data displayed on the WinForm is updated accordingly.

　　The specific implementation is as follows:

1. Page HTML code

<! DOCTYPE HTML Public"-//W3C//DTD XHTML 1.0 transitional//en" "HTTP://WWW.W3.ORG/TR/XHTML1/DTD/XHTML1-TRANSITIONAL.DTD">"http://www.w3.org/1999/xhtml"> "Content-type"Content="text/html; charset=gb2312"/> "oraans://parameters for incoming EXE files">Open 1</a> <br> <a href="oraans://parameters for incoming EXE files">Open 2</a> <br> <a href="oraans://parameters for incoming EXE files">Open 3</a> <br> <a href="oraans://parameters for incoming EXE files">Open 4</a> <br> </div> </body>
2, the page starts the program is through the registration form to start
Xxx.reg Operation Registry File code
Windows Registry Editor Version5.00[Hkey_classes_root\oraans]"URL Protocol"="E:\\debug\\xxx.exe" @="Oralanswerprotocol"[Hkey_classes_root\oraans\defaulticon] @="e:\\debug\\xxx.exe,1"[ Hkey_classes_root\oraans\shell] [Hkey_classes_root\oraans\shell\open] [hkey_classes_root\oraans\shell\open\ Command] @="\ "e:\\debug\\xxx.exe\" \ "%1\""
3, WinForm program processing the parameters passed in the page (based on C #)
1), Program.cs file code
usingSystem;usingSystem.Collections.Generic;usingSystem.Linq;usingSystem.Windows.Forms;usingSystem.Text.RegularExpressions;usingMicrosoft.Win32;usingSystem.Threading;namespaceoraans{Static classProgram { Public StaticEventWaitHandle programstarted;//event wait handle        /// <summary>        ///The main entry point for the application. /// </summary>[STAThread]Static voidMain (string[] args) {            if(args.
