    How to use OCX?

    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 .InteropService s.COMException'
    occurred in ActiveGS.NET.ex e

    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.IHTMLDoc ument2
      htmldoc2 = CType(WebBrowse r1.Document.Dom Document,
      mshtml.IHTMLDoc ument2)

      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
          "Catastroph ic Failure" with no further explanation. Could be this OCX is
          not compatible? Or maybe I need to use Interop to work with it?

              Hi,
              [color=blue][color=green]
              >>[/color][/color]
              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).
