how to create activeX in .net VB?

[S. Ahmed]

Hi all:

I am new to VB, especially to VB .NET. I need to create an ActiveX DLL
that I can then use in another application (LabView). I know in VB
6.0, creating ActiveX DLL was easy. The documentations says, 'class
library' now replaces ActiveX DLL. Also, someone told me that an
ActiveX DLL can be exported from .NET VB.

I would really appreciate some help. A simple example would be
awesome.

Thanks in advance.

ActiveX exposes COM which can be exported in VB.NET (still requires a
managed runtime though). You cannot build ActiveX (OCX) controls with
VB.NET, at least what I've seen, but you can expose it to the com interop.

You cannot create ActiveX components/controls any more. All you can do, is
marking a library for use with COM interop. The sample below shows how
to create a very simple .NET DLL and use this DLL in a VB6 project:
