Your code compiles fine on my system (skeleton DLL created by Visual C++ 2010 express). How did you create your project?

You are returning a different type of string that is defined in your function definition.

Look at this article about the different types of strings (see the table at the end for an overview):

What has it to do with the error message?

Oh you're right, somethings missing in OPs question.
