Attaching to a child process automatically in Visual Studio during Debugging
提问by Sam Saffron
When writing plugins for media center your plugin is hosted in ehexthost.exethis exe gets launched from ehshell.exeand you have no way of launching it directly, instead you pass a special param to ehshell.exewhich will launch the plugin in a separate process.
当为媒体中心编写插件时，你的插件托管在ehexthost.exe这个 exe 中ehshell.exe，你无法直接启动它，而是传递一个特殊的参数ehshell.exe，它将在单独的进程中启动插件。
When we are debugging media browserI find the process of attaching to a second process kind of clunky, I know about Debugger.Attach and also of some special registryentries I can use.
当我们调试媒体浏览器时，我发现附加到第二个进程的过程很笨拙，我知道 Debugger.Attach 以及一些我可以使用的特殊注册表项。
Both these methods don't exactly fit my bill. What I want is to press F5 and have my current instance of visual studio attach to the child process automatically. Can this be done?
这两种方法都不完全符合我的要求。我想要的是按 F5 并让我当前的 Visual Studio 实例自动附加到子进程。这能做到吗？
If there is a plugin for VS that allows me to achieve this functionality I would be happy with it.
如果 VS 有一个插件可以让我实现这个功能，我会很高兴的。

I ended up going with the following macro:
我最终使用了以下宏：
Public Sub CompileRunAndAttachToEhExtHost()
DTE.Solution.SolutionBuild.Build(True)
DTE.Solution.SolutionBuild.Debug()
Dim trd As System.Threading.Thread = New System.Threading.Thread(AddressOf AttachToEhExtHost)
trd.Start()
End Sub
Public Sub AttachToEhExtHost()
Dim i As Integer = 0
Do Until i = 50
i = i + 1
Try
For Each proc As EnvDTE.Process In DTE.Debugger.LocalProcesses
If (proc.Name.IndexOf("ehexthost.exe") <> -1) Then
proc.Attach()
Exit Sub
End If
Next
Catch e As Exception
' dont care - stuff may be busy
End Try
Threading.Thread.Sleep(100)
Loop
End Sub
Also, I outlined the process on how to get this goingon my blog.
另外，我在我的博客上概述了如何实现这一点的过程。

I would use a macro. I've redefined my F5 function to attach to the asp.net process instead of the long build/validate it usually performs. This works pretty well for me and it's really easy.
我会使用宏。我重新定义了 F5 函数以附加到 asp.net 进程，而不是它通常执行的长时间构建/验证。这对我来说非常有效，而且非常简单。
For Each process In DTE.Debugger.LocalProcesses
If (process.Name.IndexOf("aspnet_wp.exe") <> -1) Then
process.Attach()
Exit Sub
End If
Next

You can automatically attach to a process by pressing F5, if you setup something like that in visual studio:
如果你在 Visual Studio 中设置了类似的东西，你可以通过按 F5 自动附加到一个进程：

http://vvcap.net/db/ujYL7zeN_n_RgeprqCSM.htp
notice: There's "Command" filled up as an executable name, and "Attach" must be "yes"
注意：“Command”填写为可执行名称，“Attach”必须为“yes”

For VS2012, macros have been dropped, but you can still do it quite quickly with standard keyboard shortcuts. For instance, to attach to iisexpress.exe:
对于 VS2012，宏已被删除，但您仍然可以使用标准键盘快捷键快速完成。例如，要附加到 iisexpress.exe：
Ctrl+ Alt+ p- brings up the Attach To Process dialog
Ctrl+ Alt+ p- 弹出附加到进程对话框
i- jumps to the the first process beginning with i in the list (for me this is iisexpress.exe)
i- 跳转到列表中以 i 开头的第一个进程（对我来说这是 iisexpress.exe）
Enter- attaches
Enter- 附加
For super speed, you can also Turn off Visual Studio Attach security warning when debugging IIS.
为了超速，您还可以在调试 IIS 时关闭 Visual Studio 附加安全警告。

I was debugging a C++ plugin in an externally spawned process that crashed by throwing an exception at startup and this worked perfectly for me:
我正在一个外部生成的进程中调试 C++ 插件，该进程因在启动时抛出异常而崩溃，这对我来说非常有效：
Add the free Reattach Extension for Visual Studio. Ask it to reattach to the process name before it is launched. It will pop a modal dialog saying it is waiting for the process name to launch.
添加免费的 Visual Studio 重新附加扩展。在启动之前要求它重新附加到进程名称。它会弹出一个模式对话框，说它正在等待进程名称启动。
Now launch the process and the Visual Studio debugger will attach immediately, catching exceptions and hitting breakpoints.
现在启动进程，Visual Studio 调试器将立即附加，捕获异常并命中断点。
(This was also in a media plugin, the exception was normally caught and rethrown by the host process in a Delphi context so I needed to break before that happened).
（这也是在媒体插件中，异常通常由 Delphi 上下文中的宿主进程捕获并重新抛出，因此我需要在发生之前中断）。
