I have question to ask.
I have a dll file written for reading&writing data on USB. To use dll in VB.Net, one needs to integrate a .vb file which interface to that dl
Reference the C# dll in the VB project (or just drop the dll into the /bin folder)
As you know, you need to adapt the VB.NET code in the form class to C#.
In Answer to your question instead of a call from VB.NET Form codebehind:
iConnectToHID(Me)
You would use
iConnectToHID(this);
