Dll made in C using in vb.net

Hi there, I'am making an example program that uses a dll compiled i C(unmanaged).
But i keep getting an error:"{"PInvoke restriction: cannot return variants."}

I used following declare statement:

Declare Function som Lib "dll_som.dll" () as Integer


the call is like this:"som" is a function in the dll.

TextBox3.Text = som(A, B)

Can enyone explain me how to do it properly!

Thanks!
