I already saw this question passing by in the news group, but I could not
make up answer from it.
I have an object say TestObject that has a public method (only to explain
the problem):

I have an object written in traditional C++ COM, it is an Apartment threaded
object, this aggregates any number of other COM objects, written in any
language capable of implementing COM.
I have encountered marshalling problems when one of the COM objects being

How can I using interop (C# or VB.net)
1) Get a list of reports in an access database
2) Programatically change the "Control Source" of a report. ie. perform a
search and replace - eg. CustName becomes CustomerName.

Greetings all,
I'm having a very challenging problem.  We have a VB.NET middle-tier
assembly (.DLL) made up of several classes.  The code needs to run
both periodically and on-demand, so we decided to use some very

We have developed a web application, which uses Interop.Word.dll
to read from word documents and write to word documents. Problem
is that our client is persisting that we develop the solution in
such a way that the app can be deployed in a machine where Office

I've been trying to build a wrapper to use with the Authentec SDK for
fingerprint scanners. I am a .Net newbie and cannot get the interop dllimport

Here is the .h function definition:

I've got a memory leak problem with my Stack in a class I created for Serial

I've narrowed it doen to a subclass I created to monitor the Win32 events
fired for the Serial Port (Using WaitCommEvent).

I am attempting to create an Outlook COM AddIn that works with Outlook 2000
and later.  It appears that I must cast certain events in order to do so.  I
found code similar to my example below:
      ((Outlook.ExplorerEvents)this.ActiveExplorer).Close+=new

I have a COM AddIn written in C# that I compiled and built on a Windows 2000
/ Office 2000 machine.
Now, after installing it on a Windows XP / Office XP machine, when the
application tries to register a delegate for the Explorer 'Close' event, I

I have a Visual C++ 6 MFC app which uses .NET COM (built with 1.1) objects.
I have installed .NET 2.0 beta and now I find that CoCreateInstance crashes
when trying to create the .NET COM objects.
This is extremely easy to reproduce:

I have been using CoMarshalInterface and its reverse in C++ to convert a COM
interface
pointer to a string that I could pass to an ActiveX control, and also to
pass an interface back

When I use tlbimp on Shell32.dll there is no reference to IActiveDesktop or
to the CoClass which implements this interface. Can anyone tell me why this
should be the case? Will I have to hand-craft the COM wrapper or is there a
quicker way?

I am trying to implement a COM interface, defined in a Type Library, in a
VB.Net COM Class.
At this point it is a proof of concept project and I am trying to use the
minimum amount of code but I have to implement the interface
