calling unmanaged c++

[Jacob Gladish]

Can someone provide a small snippet of how to call unmanaged c++ from within
a c# application. The code is in a .lib file, and not in a .dll. Can you
include headers in c# !!???

Jacob,

The code is in a .lib file, and not in a .dll.

In that case you must first link it into a DLL to be able to use it
from C#.

Can you include headers in c# !!???

No

You cannot link a lib directly with a C# program.

Write a c++ wrapper for the lib and access it using pInvoke.

Even for a dll file, if not a COM, can we use it in C#? If we could,
is there any sample project which show the way to do it? Thanks

I have a managed C++ class that calls AdjustTokenPrivileges, from the
MS Win32 call list.
I just use (my namespace is ACLabLoginUtil)
using ACLabLoginUtil

and that allows my C# program to use the C++ functions.

I had to include the file in my project though, as a reference, but
that was it.
