How do you determine at runtime whether the visual studio debugger is attached to your process. I've seen instructions for how to do this in .NET, but my process is a native C++ process. Support for detecting Just-in-time debugging would be nice but not a strict requirement.

Are you asking for a way to detect if the debugger is attached from within the process the debugger is attached to, or from a different outside process? – tloach May 07 '10 at 14:48

from inside the process the debugger is attached to. IsDebuggerPresent worked as suggested below. – Jeremy Bell May 07 '10 at 15:34

1not really a dupe (although the IsDebuggerPresent function was mentioned) - that question was for .net specifically. This is for C++/Win32. – Jeremy Bell May 07 '10 at 17:31

The Win32 call IsDebuggerPresent() sounds like it ought to work.

I used this approach but then saw the blog in the following link where he claims he dissabled IsDebuggerPresent through a script, so this approach can be problematic: https://blogs.msdn.microsoft.com/debuggingtoolbox/2007/05/23/windbg-script-disabling-isdebuggerpresent/ – TBD Mar 22 '16 at 06:31

+1 for being the right answer, even if 2 minutes later than unwind's answer. Thanks to you also. – Jeremy Bell May 07 '10 at 15:09
