Problem w/using own C++ DLL in VB

Is there anyone who can help me w/ VB6 or VB.NET?
In my VB application I have to use just one C/C++ function
so I wrapped that function to COM(ATL) dll. The problem is when I add reference to it, function runs good only once. When I call that same funcion from dll, it does not work, and I do not know why is that?

Can anyone help me pls?

ps  I already tried Declare Function .... Lib ... statement
I got same result.
