I assume you downloaded ‘k8056_vb_demo.zip’ and want to adapt that to suit your needs
The problem is that the demo application is written in Visual Basic 6.0, and you’re using Visual Basic 2008. Both names might seem identical (it’s just a newer version, right?), but the languages themselves are totally different. Visual Basic 2008 (or Visual Basic .NET) is based on the .NET framework, while Visual Basic 6.0 can create stand-alone executables.
Conversion between VB 6.0 and VB .NET can be very difficult, if not impossible…
Maybe someone has an already working example in VB .NET that you could use?
