HOWTO: using a remote COM+ object

Posted By:      Posted Date: October 28, 2010    Points: 0   Category :.NET Framework


using another IDE (SQLWindows/Unify) I created a COM-object containing some business logic. Now I want to access the methods of this COM-object using VS2010 and C#. I have the .dll and .tlb file for my COM object.

In my first try, I registered the DLL locally using regsvr32. I referenced the DLL from my C# client and can successfully call the methods in this COM object.

Now I want to install this COM object on a remote machine using the Component service. I know how to do the remote install. What I don't know is how to access the remote COM object with my C# client. From what I've found so far is, that I must create a new DLL from the .tlb file using tlbimp.exe. In my C# client for the remote com object  I need to reference this new DLL. But how do I create/activate the remote com object to call any method? Somehow I must specify the servers name or IP address. I found some code about how to call a remote com object using reflection but this thread says that this is only relevant when you don't have the .tlb

Am I right when I assume that as long as the interface of my COM object does not change, that I can install a new version on the server and the remote client will still work with the old DLL created with tlbimp. Or must I recreate this DLL with tlbimp every time?

I would be glad if someone can point me to s

Proxy failed to create remote object on the server

Hi, I am using .net remoting for inter-process communication between two processes on the same machine 1.   The first process is one of the Office application: Ecxel /   Word /   PP 2.   The other process is another application that interacts with one of the above. For that it needs office application object. For example: Excel The solution is comprised with 3 projects: Project #1: The remote object is a simple Called RemoteOfficeApplication – that simply wraps the required application object (Word / Excel / PP).   Project #2: The Server is a simple Office add-in, written with a Visual Studio Extensibility -> Shared project. This add-in is instantiated whenever Excel is lunched. This project reference project #1. Code: var channel = new TcpChannel (5003); ChannelServices.RegisterChannel(channel,true ); RemotingConfiguration.RegisterWellKnownServiceType( typeof (RemoteOfficeApplication.RemoteOfficeApplication ), “AppObj”, WellKnownObjectMode .Singleton);   Project #3: The Client is the process that requires the application object. This project also reference project #1. Code:   //Get Remote object proxy object remoteAppObject = Activator.GetObject(typeof(RemoteOfficeApplication.RemoteOfficeApplication), “tcp://localhost:5003/AppObj" ); //Cast the proxy var r

trapping connection to remote object


I have a .net Remoting application.   I would like to do some tracking when connections are made.   Is there a way to interrogate connections being made to my remote object?

I have a singleton object, running as a service.   Basically when a ui connects I want to report back the state, and any pending messages.   So by looking at the connections I can keep a ptr to the next group of messages based on the client that connected.

Any insight into this would be a big help.



Stream object is inaccessible after returning from remote layer through remoting -


In my export function I am returning the System.IO.Stream object from remote layer through remoting. But getting the stream object it becomes inaccessible when I called the remoting layer with integrated authentication. It is giving me The remote server returned an error: (401) Unauthorized exception even I access its CanRead or CanWrite property. This is happening only in case of integrated authentication. For without any authentication its working fine.

 Dim ostream As System.IO.Stream
                        oWriter.WriteLine(Now & " - Before calling GetExportData")
                        ostream = oExport.GetExportData(dsGrid, intDateType, repPage.m_strFromDate, repPage.m_strToDate, repPage.m_strProcessStatus, repPage.m_strLocation, repPage.m_strDiseaseOrGrouping, repPage.m_strDiseaseOrGroupingDR, repPage

howto access remote shared folder using remote login and password ?



I want to write some piece of code in C# to access (create directory, create files) on a remote shared folder (stored in a remote machine), but using a specific remote user and password (a user defined in the remote machine) but not defined on the local machine where my piece of code is to be run.

I can do that using the explorer: if I type \\remoteserver for exemple, I can then give a login as remoteserver\remoteuser and the password of this remoteuser to access the shared folder (the permission has been set on the remote shared folder to authorize full permission for this user)

Plesae tell me if it is possible and how I can do that using the base .NET framwork library (or any extension of it).



Thinking about new C# method prototypes: object as dictionary

I recently had to write a small Flickr API. I know many .Net API for Flickr already exist but I needed one for a Silverlight application. Whatever, it's only about building some querystrings so I did it by myself. It's been an opportunity to think again about a classical question: how to pass parameters to a method ?

Imagine you have a generic method to call some Flickr functions.

C# Object Oriented Programming

So far in C# Essentials we have looked at the basics of programming in C# such as variable types and flow control. Although it would be possible to write a functional program using these techniques, there is much more to becoming a proficient C# programmer. C# is, above all, an object oriented programming language and as such any C# programmer will be expected to create object-oriented applications using this language.

Object Oriented Programming

Four core concept of OOP Object Oriented Programming. 1.Inheritance, 2.Polymorphism, 3.Abstraction and 4.Encapsulation

Object-Oriented Programming Concepts

This is the first in a series of articles describing the use of object-oriented programming techniques as implemented by the C# programming language. This series follows the C# Fundamentals tutorial that beginners are advised to read first.

Overview of SharePoint Object Model

SharePoint offers a set of structured server-side objects those are widely used to program SharePoint Applications. These objects are hierarchically arranged and you can drill down through the object hierarchy to obtain the object that contains the components of SharePoint Application you need to use in your code.

What is the difference between "dynamic" and "object" keywords?

Let's take a quick look at the object keyword first. I'm not going to talk a lot about it because it's been around since C# 1.0. This keyword is nothing more than a shortcut for System.Object, which is the root type in the C# class hierarchy. (However, as Eric Lippert pointed out in his blog post, not everything in C# derives from object.) This is a powerful mechanism, since you can assign almost any value to instances of this type.

How to bind GridView and DropDownList controls using DataTable object

In .net framework 2.0, you can load a DataTable in memory by consuming a data source using a DataReader. In this version you will find the flexibility in accessing the DataReader means write access code once and use again and again using DataReader. To see the functionality of DataTable consider an example that is created using VS2005.

Jscript error: Object does not support property or method


 Hi, i have little knowledge on javascript but i need to use this code get from somewhere for a jquery to work.

I face this "Jscript runtime error: Object does not support property or method" whenever im trying to run this page.

In my experience, im get this error msg 9 out of 10 times i use javascript in my system.

Im using Microsoft Visual web developer 2008, i wonder if this is related to my problem, i not sure there is anything i need to add as reference or update anything.

But anyway, in short, i just couldn't use javascript code when using this development tool because of this sort of error.

Anyway, it happen that last time i tried use the same type of jquery code in another project and it seems to work well without an error.

But now when im try to use it again in this recent project i created, it come out with this error and i have no idea how to solve it even look through google and this forum.

It doesn't really seems like its the code problem itself although im not sure, because any javascript code just couldn't work.

So below is my code that i need to use.

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js" ></script>
<script type="text/javascript" src=&quo

VS2010 Professional .NET 4.0 Remote Debugging ASP Website Project


Trying to remote debug ASP website from VS2010 Pro to Windows Server 2003 machine.  Specifically, trying to debug a Web Service, but breakpoint says, "The breakpoint will not currently be hit. No symbols have been loaded for this document."  This happens for all compiled code though.  I have read this is due to missing PDB files and the work around is to manually copy them, as noted here.  Problem is, I cannot find any PDB files for my project, except referenced libraries, which I can remote debug.


  • web.config has <compilation debug="true">
  • Debugger is attached to wewp.exe process on remote server
  • Installed VS2010 remote debugger from DVD (as I can remote debug referenced libraries)

This is beyond frustrating.  I migrated my code from VS2008 .Net3.5 to VS2010 .Net4.0 to take advantage of the inherent multithreading framework.  Debugging works when using local host and was stable until deployment to test server.

Thanks in advance,


Pass ASP.NET membership identity object across domain?


I am trying to figure a way to SSO with ASP.NET membership and role model.

I can implement custom membership provider which consume web services hosting on a server.

With encryption of data. No problem.

But my question is, If I sign on a website with my provider, got my identity object on that application,

could I pass it to another website on another domain which use the same provider and by doing so, do not need to login again?

If this is possible, I am going to implement this solution. Please tell me what's your take on this.

Send object from one page to another



I want to create object in 1.aspx, and then send it to 2.aspx. This methods are bad, because:

1)Send object with url, like this:


This is not confidential.


Session["field1"] = "12345"; // set
Object foo = Session["field1"]; // get

This is bad too, because in 2.aspx this fields send to textboxes, and if user go to 2.aspx without 1.aspx, he'll see old data. 

How do I preserve __viewstate between cross domain posts or how do I get a __viewstate of a Remote S


Here is what I want to do:
I have a local site in which I want to display data from a remote site
Lets say: I want to display data of http://www.abc.com/Default.aspx on my localhost

Now Default.aspx requires some post-data which it sends to itself. Thus the __viewstate and __eventvalidation are posted back to it by itself. I want to directly post the data to Default.aspx from localhost without opening Default.aspx and display the Default.aspx's response on my localhost.

The WebApp on http://www.abc.com is configured for __eventvalidation i.e. I cannot post-data to it from my localhost without getting a __viewstate from it. I also have to post the current __viewstate of http://www.abc.com/Default.aspx to itself

How can I accomplish it?
