How to start a process and then pause it immediately?

I would like to know if there is any command or tool that can be used to start a process and then pause it immediately.

I need this function so that I can have time to attach a debugger to it. I have tried visual studio's /debugexe feature, but the behavior of the program seemed changed. So I need to find other way to attach it and debug.

Thank you.

In your main routine insert the line:

    System.Diagnostics.Debugger.Launch();

Compile in debug mode. Run your program and it will break and prompt you to attach a debugger. If you have studio open it will ask if you want to use it to debug.

You can also add a call to

System.Diagnostics.Debugger.Break();

in the code. It will suspend the program and then ask you to choose the debugger you want to use. You can then attach to a running Visual Studio instance. If you're already running from a debugger, it will simply break as if it would have hit a breakpoint.

How about adding a Sleep() call as the very first statement.

You can use CreateProcess() with CREATE_SUSPENDED flag. This will start the process with the main thread suspended. Then you call ResumeThread() after having attached.
