Hello. I have written a Class Library in C# that has two methods:
GetNumber returns 17
GetName returns foo
I am able to add a reference to the COM object from an ASP.NET page,

For the life of me I cannot get this API function to work as expected
in VB.Net
I am however using SetWindowPos, and so long as the window is not
minimized, it will position as I tell it to. If the window is

I have a strange issue when using a COM component in VS 2005 or 2008. If I
compile my application and run it, it works on any xp machine, but does not
work on most vista machines. I get an "Attempted to read or write protected

Hi...
One of my colleagues is have a problem that's driving him crazy.
We have a number of assemblies that expose some C# objects as COM.  One

Hi...
Just out of curiousity, I was wondering if the InprocServer32\RuntimeVersion
registry setting of a .Net COM interop object had any effect?
I happened to notice the other day that our Wix msi projects errorneous

I have an assembly that references a COM DLL that uses ADODB.  It runs
properly when run from a regular .Net program, but I need it to run from SQL
Server 2005.

Is there a way to save a dynamically created Excel workbook to a
Memory stream?  There are no overloads in the Save method to save to a
stream.  I want to create a web service that will dynamically generate
an Excel file, but do not want to use a temporary file for each call.

Setting this property when no workbook is open throws an exception. Is this
the intended behavior?

Is there a way to insert both cs & vb files in a dotnet 1.1 vbproj or
csproj file?
I guess I could compile them into lib files and then interlink?

I am trying to create a unit test in .NET that tests the COM API of
a .NET assembly that was registered for COM interop (regasm). So the
call sequence is like: .NET -> PIA -> .NET. What seems to happen is
that a RCW is created that tells the CLR that the underlying type of

Hi, I notice that Marshal.GetNativeVaraintForObject is a way to create
a variant from object.
But DotNet can do marshalling from object to variant when an object is
used as a parameter.

I will get a compiler Error when trying to implement an interface,
using ActiveX-types as parameters in VB.NET.
I will explain the problem with ActiveX-ADODB v2.8 but, i can
reproduce the bevaviour with a selfwritten dummy activeX-lib.

I posted this several weeks ago and haven't received any 'real' response

=================================================
My .NET application makes a call to a DCOM server through an interop

This would better be described by 'serialization' than 'interop', but I
didn't find a newsgroup that seems closer on topic.
The problem in a few words: I save data with DataSet.WriteXML, but I get
different data back when I read it later with DataSet.ReadXml.

Scenario :
1.    The Department files to be accessed are present in the File server.
2.    The Code is present in a different server with OS being Windows Server
