如何以编程方式将进程附加到当前调试器? [英] How to attach a process to the current debugger programmatically?

问题描述

我在解决方案中有2个项目可以编译为 A.exe 和 B.exe .A将启动B并通过管道连接到它.我想测试它们之间的连接，因此我想同时附加两者.每次手动进行操作都很繁琐且不便，所以我尝试了

I have 2 projects in the solution that compile to A.exe and B.exe. A will start B and connect to it through a pipe. I want to test the connection between them so I'd like to attach to both at the same time. Doing that manually every time is very tedious and inconvenient so I tried this

if(IsDebuggerPresent())
    DebugActiveProcess(processId);

但是，似乎 B是附加到A的调试器而不是Visual Studio的.那么如何将B自动附加到VS调试器 ?

However it seems B is attached to A's debugger instead of Visual Studio's. So how can I attach B to VS debugger automatically?

我手边有windbg来调试故障转储，所以它也可以是一个解决方案，只要它可以在没有多个用户交互的情况下完成即可.

I have windbg at hand for debugging crash dumps so it may also be a solution, as long as it can be done without multiple user interactions

推荐答案

以编程方式附加到进程 B

Attach to a process B programatically

方法1:使用VS

Method 1: Using VS

1. 打开 B.vcxproj ，而不是您的解决方案( .sln 包含项目 A 和 B 的项目)
2. 设置断点

1. Open B.vcxproj and not your solution (.sln containning projects A and B)
2. Put your breakpoints

1. 在项目 A 中通过 system()(或其他变体)运行以下dos命令:

1. Run this dos command from your project A via system() (or other variant):

devenv/nosplash/run"G:\ Logiciels \ B \ B.vcxproj"/nosplash/debugexe

devenv /nosplash /run "G:\Logiciels\B\B.vcxproj" /nosplash /debugexe

devenv 是VS路径中的命令.就我而言:

devenv is a command in your VS path. In my case it in:

C:\ Program Files(x86)\ Microsoft Visual Studio 10.0 \ VC

C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC

运行此命令时，将打开B项目并到达断点.

When you run this command, B project is opened and break point reached.

方法2:使用Windbg

Method 2: Using Windbg

只需调用此命令:

windbg -p ProcessID

以图形方式附加到进程 B

Attach to a process B graphically

在另一个实例中打开您的B项目，并像这样附加到它:

Open your B project in another instance, and attach to it like this :

然后选择您的B.exe:

And select your B.exe:
