I am using an ActiveX control in a VB.NET application as there is no
alternate .Net control available to me. The problem is that when I try to
install this appliaction on another machine the DLL is not registered. The
only way aound this that I have found is to build a ismple VB6 application
purely to register the DLL what am I doing wrong? An Interop is being
created. I have been unable to find any information on this one and it ha
been annoying me for months. The VB6 method works fine, I just want a neater
way by VB.NET of achieving this.

Best wishes

Those using my application are far from computer literate - tell them to
bring up Run from the Start menu, and they would be lost. I was wondering of
I was missing a way to get a dll automatically registeredduring the
installation process. Otherwise I will have to continue with my VB6
installer first.

Best wishes

Paul,
What do you use for installation tool? Most of the installers provide an
option to register a DLL/OCX automatically.

As an alternative solution, you can register the control programmaticaly
when your application starts up. Below is a VB .NET code snippet from .NET
framework SDK documentation that you can use as a starting point for
registering the control and creating the interop programmatically.

Hope this helps
