Dear friend,

we have a device .dll written in Visual C++ 6.0,

how to write a wrapper class in VB .NET so it can take care of converting
the parameters from C++ to VB .NET ?

Tks,
hendy

If the C++ dll is set up for COM, you shouldn't need to write anything. You can add a reference to the COM dll from visual studio and it will create the COM interop wrapper for you.

Also, the Visual Studio.Net SDK has a Type Library to Assembly converter: tlbimp.exe. You can run this manually to tweak the way the interop wrapper is created.
