[GD-Windows] Debugging multiple apps

[Research <res...@ga...>]

I cannot figure out how to debug multiple apps in Visual Studio, and I can't 
seem to find the right google words to find this either.

I'm have one application that launches another with ShellExecute. They are 
both in the same solution. I put breakpoints on the WinMain of the launched 
app and it never gets called.

I know how to attach to something already running, but I need to trap the 
app on entry. So I want to step on the ShellExecute and have the other app 
start and immediately break.

Is this possible in Visual Studio?

Thanks,
Brett

You can use gflags.exe (google it) to specify that the second application
should always be launched with a debugger attached.  This would be a
separate instance of Visual Studio, however.

One way I've dealt with stuff like this in the past is to put a simple
loop like this as the first thing in your WinMain:

    bool wait =3D true;
    while (wait);

Once the process is launched, just attach to it with the debugger and
break.  Set wait to false and start stepping.

[Brett B. \(Research\) <res...@ga...>]

I'm glad to hear this is a valid technique! I resorted to a MessageBox as 
the first line so I can attach the process before continuing.

But surely there's a way to do this properly? The doc goes on and on about 
how great solution files are because each project and the dependencies are 
known and so multi-language, multi-project debugging "is a breeze"....

I want to feel the wind in my hair!

[Alen L. <ale...@cr...>]

Hi Brett,


Using "_asm int 3 ;" is even easier. It will ask you to do JIT
debugging (if this is configured properly), so no need to manually go
and attach to the process. And you can reuse the same devstudio
instance. Didn't use this often, but the little I did, it worked ok.

HTH,
Alen

Re: [GD-Windows] Debugging multiple apps

[Chris C. <can...@gm...>]

VS.NET 2003 I know has facilities to enable multi-process COM
debugging. So when your primary process calls a COM call that causes a
second process to be created, VS is quite happy to attach and debug
the second process, allowing you to step into COM calls as if they
were local functions. I never tinkered with it to see about
auto-attaching to running processes, but Alen's right about the JIT
debugging happily offering up the running VS instance, even if its
already debugging a different app.
