Can anybody explain me how do we use DLLImport in C# for user defined functions. i.e
I have a function GetMessage() defined in VB6.0.
I know, I can import it using TLBIMP.exe. Can I use the function using DLLImport in c#. If I can, what are the steps required to do so.

Please explain

Solution 1

something like:

C#

[DllImport("TestLib.dll",CallingConvention=CallingConvention.Cdecl)]
public static extern string GetMessage(  );

perhaps?

you'd have to double check the calling convention from c# to VB
