How can I debug a process (1.exe) under another process (2.exe)?

Question

1.exe does not give me time to run the IDE and attach 1.exe to the debugger to break into it.

Answer 1

I would suggest using the same approach as for NT services in this case. They will also start and usually do not give you enough time to attach a debugger for startup procedures.

Details are described here: http://www.debuginfo.com/articles/debugstartup.html

In short, you add a registry entry for the second exe:

HKLM \ Software \ Microsoft \ Windows NT \ CurrentVersion \ Image File Execution Options \ 2.exe Debugger = "C: \ Progs \ MSVS \ Common7 \ ide \ devenv.exe / debugexe" (REG_SZ)

c:\progrs\msms\ .

Answer 2

Answer 5

If you want to consider a debugger other than Visual Studio, WinDBG can automatically debug child processes (native code only).

Answer 6

You did not indicate which language you are using. But if you use C # or VB.NET, you can add Debug.Break () or Stop to trigger a request to attach the debugger to the process.

Or, as mentioned above, just use something like Console.Readline () or MessageBox.Show () to pause the process until you can connect a debugger to it.
