.NET to COM question ( Dictionary in COM and .NET dictionary)
I need to write a data access code to replace the method of GetPerson() in COM data access, since the existing method is too slow. .NET can reduce the database round trips by using the dataset. The existing COM data access will stay except the GetPerson() method.
So I am going to call the .NET getPerson() mehtod from the COM,
The original GetPerson() method in COM just go to data base, pull data from 7 tables and write to dictionary.
If the .NET getPerson() can populate the COM Dictionary, that would be great!

You need to use the tlbexp utility to generate a COM typelib from the .NET
assembly you're trying to access. You then use the TLB to register a COM
proxy you can invoke from EAS.

Here is my situation. I have an application that I developed in .NET which uses a COM object from a 3rd Party document management system (Interwoven). In my development environment the code works fine. However when I push the code to the test server (package msi or manual move over) when I try to login to the application I get an error stating "Cannot request exclusive semaphores at interrupt time. ". One thing I have noticed is that when I recompile the application in dev an Interop dll for the COM object is created. If I remove the Interop dll then I g...COM Component in .Net

...Accessing a COM .NET Assemby (with Sharepoint Client Objects) from Delphi w
Really nice if someone could help use with this .NET assembly access problem!
We have a problem of accessing Sharepoint Client objects from our win32 Delphi application (Document management), developed in Delphi XE. We have built a .NET COM assembly that encapsulates the Sharepoint Client objects and we generate a pascal TLB from this, our .NET assembly. Calls that are not routed to the Sharepoint Client objects work, but immediatelly when trying to get access to Sharepoint Client Objects, through our .NET COM assembly there seems to be a exception loop started within the Sharepoi

I am developing a .Net web application using VS 2005. I have referenced a COM component(Microsoft component) from my .net application. Since the COM is unmanaged, a wrapper class is been created. Well and good. Now I have 2 questions.
Q1.What happens when I upgrade my VS2005 to VS2007 next year. Will that COM component and wrapper class will still be compatible?Q2. What if I get a newer version of that COM ? Do I need to create a new wrapper class. Will that throw any error?

HELP!!
We are facing an issue when we have a .net Winforms application that uses
a PB 11.1 COM .dll file. Both the winforms app and the PB dll connects to
the same Oracle database.
This works fine if the database is e.g. MSSQL 2000 / 2005.
The error we have is as good as identical to a bug that should have been
fixed in Sybase Rollup Maint 15249 11.1 maint (http://download.sybase.com/swr/10663/EBF15249_README.html)

Does anyone have an idea how to correct this?....NET classes hindering .net assembly from being com?
I posted an earlier thread about instanciating a .net assembly from a com client, like an asp page. My problem was that no matter what I did, I could not get the class to instaciate, so I could not call any methods on that class.
After quite a bit of trial and error, as far as weak and strong named assemblies, GAC, etc, I came to the conclusion that the object WAS being referenced properly, therefore it was not a problem getting access to the object's class declaration. My problem was that everytime I called a method on the object, I got a "object not set to instance" error.
We are planning to deprecate the COM/COM+ component wizard in
PowerBuilder 11.5. Alternatives are deploying your NVO as a .NET Web
Service or as a .NET Assembly. Would removing this feature have an
impact on you?
We are using many many COM/COM+ components.
