I have an OCX that I used in VB6 (there is no .NET version of it).  There
was an INI file with it.  I right-clicked the INI file and chose "Install"
and rebooted.  I then created a new VB project and added a reference to the
OCX. I tried to create an instance of the OCX via "dim MyOCX as new
ActiveGS".

When I run the program I get:

An unhandled exception of type 'System.Runtime.InteropServices.COMException'
occurred in ActiveGS.NET.exe

Additional information: COM object with CLSID
{052DF14F-6F28-44A0-9130-294FDA6176EB} is either not valid or not
registered.

In VB6, this OCX appears in the toolbox and I can drag it onto the form as
it has a UI.  So, in VB.NET, can this appear in the toolbox as a drop-in
control?

Or how could I go about using this OCX in VB.NET?

Thanks.

once the refernce is added you should be able to access it directly
through the RCW.  for example, I have a project that references
mshtml.dll.  I use it with code like this:

Dim htmldoc2 As mshtml.IHTMLDocument2
htmldoc2 = CType(WebBrowser1.Document.DomDocument,
mshtml.IHTMLDocument2)

which is not your exact case, but may point you in the right
direction...

why do you want to host an Apple ][gs emulator in .NET?

Something to do...why not?

Actually, I've hit another snag.  I figured out that I needed to register
the file using regsvr32.  I got past the original problem and I can
instantiate the object, but when I call any visible method, I get
"Catastrophic Failure" with no further explanation.  Could be this OCX is
not compatible?  Or maybe I need to use Interop to work with it?

Hi,

I tried to create an instance of the OCX via "dim MyOCX as new
ActiveGS".

After registering the OCX, add it to the ToolBox and drop in on a form.
This creates the wrapper DLL that .NET needs.  Then, just use the methods,
properties and events in the same way you would in a VB6 project.  Do not
attempt to create it at runtime (as in your code).
