Checking if Debugger is present in c++ dll (loaded in C++/CLI wrapper)

Question

I'm checking if a debugger is present in my c++ dll with method

if(IsDebuggerPresent()) // set dll name to debug

When I load this dll in my C++/CLI wrapper (debug mode in VS) the method always returns false (release) -> why is it so? (or which code I need to determine this information)

Thank you for your help!

Wait, are you saying "it is false in debug build" (i.e. wrapper is built as "debug") or "it is false when _run from_ the debugger"? Those are different things. — Damon, Jul 05 '11 at 14:26
That was the solution: just enable unmanaged debugging ! (http://msdn.microsoft.com/en-us/library/tdw0c6sf.aspx) — leon22, Jul 05 '11 at 15:17

System.Diagnostics.Debugger.IsAttached returns true if a debugger is attached to your application. Is this what you are trying to achieve?

I know this method, but this is only for managed .net code -> I'm into an native C++ dll (loaded from .net C++/CLI wrapper)! – leon22 Jul 05 '11 at 15:04
