Using a COM with VB.Net
I am trying to use a COM with VB.Net and it sounds like I need to create a "wrapper" to use it.I read the article here:
http://www.csharphelp.com/archives2/archive437.html
but Im still having problems. When I go to the command prompt and try to run tlbimp.exe it doesnt work. When I type in "tlbimp" it says "'tlbimp' is not recognized as an internal or external command, operable program or batch file". I do however have it on my machine.
HEre is the code I am running in my program, which is generating COM exceptions.
Imports System
Imports busobj
Imports System.Runtime.InteropServ
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim BusObjApp As New busobj.Application
Dim BusObjRep As New busobj.Report
When I try to create the new business objects report I get the COM exception.
"Retrieving the COM class factory for component with CLSID {2AE0D397-5F2A-11D0-8B75-0
I've been stuck on this for a while now....and ideas would be greatly appreciated.

I am running VB 2005 express.
The COM component is part of Business Objects 6.1. I am trying to automate running reports. The COM is the busobj import in the code I posted. It is called "BusinessObjects 6.0 Object Library".

You should be able to add a reference to a COM through the 'Add Reference' dialog box. .NET will create the wrapper class for you automatically (Interop.dll).

Ok...maybe I have another problem then. I added the reference and have the following code right now:
Imports System
Imports busobj
Imports System.Runtime.InteropServ
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim BusObjApp As New busobj.Application
Dim BusObjRep As New busobj.Report
But when I try to create the new report I get the COMException.
Is there something wrong with my code, or does this look like another problem?

How do I check to make sure the COM library is installed? I think it is becaise I can run the application (Business Objects) just fine.
There is a convoluted way, by looking through the registry under HKEY_CLASSES_ROOT\CLSID for the {2AE0D397-5F2A-11D0-8B75-0

Well, I think this might be my own noobness (is that word?) at work here.
Instead of creating a new report I noticed I have the option to create a new document. Well, I created that and it doing everything I need it to do.
I dont have any documemtation on the business objects library so Im kind of poking in the dark here, but for now I think im cool to move forward. Thanks for your help guys.

2) Where was the COM component created?
