在新的浏览器进程中打开一个URL [英] Open a URL in a new browser process

问题描述

我需要在一个新的浏览器进程打开一个URL。我需要在该浏览器进程退出时得到通知。我目前正在使用的代码如下：

I need to open a URL in a new browser process. I need to be notified when that browser process quits. The code I'm currently using is the following:

        Process browser = new Process();
        browser.EnableRaisingEvents = true;
        browser.StartInfo.Arguments = url;
        browser.StartInfo.FileName = "iexplore";

        browser.Exited += new EventHandler(browser_Exited);

        browser.Start();

显然，这不会因为因为文件名固定IEXPLORE，而不是用户的默认网页浏览器。我如何找出用户的默认Web浏览器是什么？

Clearly, this won't due because the "FileName" is fixed to iexplore, not the user's default web browser. How do I figure out what the user's default web browser is?

我在Vista-运行>转发。虽然XP将是很好，如果可能的支持

I'm running on Vista->forward. Though XP would be nice to support if possible.

多一点背景：我创建了一个颇有些文件从本地磁盘一个非常小的独立的Web服务器。在启动服务器的最后，我想启动浏览器。一旦用户完成并关闭浏览器，我想退出Web服务器。上面的代码完美的作品，除了只使用IE浏览器。

A bit more context: I've created a very small stand-alone web server that serves some files off a local disk. At the end of starting up the server I want to start the browser. Once the user is done and closes the browser I'd like to quit the web server. The above code works perfectly, other than using only IE.

在此先感谢！

推荐答案

确定。我现在有工作的C＃代码，做我想做的。这将返回命令行，你应该运行加载当前默认浏览器：

Ok. I now have working C# code to do what I want. This will return the "command line" you should run to load the current default browser:

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

namespace testDefaultBrowser
{
    public enum ASSOCIATIONLEVEL
    {
        AL_MACHINE,
        AL_EFFECTIVE,
        AL_USER,
    };

    public enum ASSOCIATIONTYPE
    {
        AT_FILEEXTENSION,
        AT_URLPROTOCOL,
        AT_STARTMENUCLIENT,
        AT_MIMETYPE,
    };

    [Guid("4e530b0a-e611-4c77-a3ac-9031d022281b"), InterfaceType(ComInterfaceType.InterfaceIsIUnknown)]
    public interface IApplicationAssociationRegistration
    {
        void QueryCurrentDefault([In, MarshalAs(UnmanagedType.LPWStr)] string pszQuery,
        [In, MarshalAs(UnmanagedType.I4)] ASSOCIATIONTYPE atQueryType,
        [In, MarshalAs(UnmanagedType.I4)] ASSOCIATIONLEVEL alQueryLevel,
        [Out, MarshalAs(UnmanagedType.LPWStr)] out string ppszAssociation);

        void QueryAppIsDefault(
            [In, MarshalAs(UnmanagedType.LPWStr)] string pszQuery,
            [In] ASSOCIATIONTYPE atQueryType,
            [In] ASSOCIATIONLEVEL alQueryLevel,
            [In, MarshalAs(UnmanagedType.LPWStr)] string pszAppRegistryName,
            [Out] out bool pfDefault);

        void QueryAppIsDefaultAll(
            [In] ASSOCIATIONLEVEL alQueryLevel,
            [In, MarshalAs(UnmanagedType.LPWStr)] string pszAppRegistryName,
            [Out] out bool pfDefault);

        void SetAppAsDefault(
            [In, MarshalAs(UnmanagedType.LPWStr)] string pszAppRegistryName,
            [In, MarshalAs(UnmanagedType.LPWStr)] string pszSet,
            [In] ASSOCIATIONTYPE atSetType);

        void SetAppAsDefaultAll(
            [In, MarshalAs(UnmanagedType.LPWStr)] string pszAppRegistryName);

        void ClearUserAssociations();
    }

    [ComImport, Guid("591209c7-767b-42b2-9fba-44ee4615f2c7")]//
    class ApplicationAssociationRegistration
    {
    }

    class Program
    {
        static void Main(string[] args)
        {
            IApplicationAssociationRegistration reg = 
                (IApplicationAssociationRegistration) new ApplicationAssociationRegistration();

            string progID;
            reg.QueryCurrentDefault(".txt",
                ASSOCIATIONTYPE.AT_FILEEXTENSION,
                ASSOCIATIONLEVEL.AL_EFFECTIVE,
                out progID);
            Console.WriteLine(progID);

            reg.QueryCurrentDefault("http",
                ASSOCIATIONTYPE.AT_URLPROTOCOL,
                ASSOCIATIONLEVEL.AL_EFFECTIVE,
                out progID);
            Console.WriteLine(progID);
        }
    }
}
