Capture .NET Remoting Calls



We have a client server application that 650 users are using everyday. Lately they have started complaining about over all slow responses and slowdowns in normal application usage like searching, reporting etc.

We are using .NET Framework 3.5 and .NET Remoting is the technology we have used for client connection to the server side. We can't remove that and use something else due to legacy application maintenance. We are using SQL 2008 R2 x64 on a very good server.

We have gone though the basic steps of making sure that all the SQL side is ok everything is well tuned but we need to convenience the client that it is not the application but the database that needs to be regularly maintained by a DBA in order for it to run smooth due to the nature of the application making tons of changes and inserts in the database everyday.

Anyways I need to write some sort of module that can plugin into the .NET Remoting calls so it can log the normal usage of different methods on the server like;

* How many times a remoting method is called

* What params a remoting method is called with

* How much time it takes to execute each remoting call

Is there anything available in .NET Framework that can help me? I read something about .NET Remoting Sync but not too sure if that is what I need to use? If any can shed any light on the subjec

Using JQuery to perform Ajax calls in ASP.NET MVC

The muscle behind the actual asynchronous calls comes from JavaScript. I looked around at a bunch of existing JavaScript libraries and settled on JQuery because of the way it leverages existing CSS knowledge. The three things that the library should do easily are:

WPF / Silverlight tutorial: Visibility property and binding

Visibility property is a very powerful and yet often overlooked property available in both WPF and Silverlight. It enables you to set Visibility of certain UIElement objects to different states like: Visible, Collapsed and Hidden (not supported by Silverlight). This tutorial shows you how to use it and how to bind to Visibility property

abstract away the source of the connection string using a class with a static property.

ASP.NET provides a configuration system we can use to keep our applications flexible at runtime. In this article we will examine some tips and best practices for using the configuration system for the best results.

The element of a web.config file is a place to store connection strings, server names, file paths, and other miscellaneous settings needed by an application to perform work. The items inside appSettings are items that need to be configurable depending upon the environment, for instance, any database connection strings will change as you move your application from a testing and staging server into production.

Let's abstract away the source of the connection string using a class with a static property.

Get pixel format, raw format, property id list and property items image in VB.net - C#.net.

n this simple article you will learn that how we can get pixel format, raw format, property id list and property items image in VB and C#.net.

Get Pixel Format:

Image consists of pixels to get the format of the pixel we have a property named pixel format. This property returns an enumeration of pixel format. This enumeration tells the pixel format.

To demonstrate make a window application. Drag one button and a picture box on form.

Now write the following code on Button click event:

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

Is it possible to populate property choices from a database?


I'm creating my first server control, and have it working where I can set up an enum and the user can set a property's choices,  based off of that enum.  But I'd like it to pull records from a database and populate the list of choices for the property from a database.  This would allow me to add a new "Host System" to the database, and the other designers wouldn't have to get a new copy of the dll.



Custom Server Control Property not maintaining state


I have created a server control consisting of a TextArea and a div under it.  My goal is to create my own asp:TextArea type control.  the div is for a Character count of the text area and seems to work ok but i added a CharacterCountVisible property to the control that is always returning true.  See Proptery definition below


<Bindable(False), Category("Appearance"), DefaultValue("True"), Localizable(True)> Property CharacterCountVisible() As Boolean
        Return _CountBoxVisible
    End Get
    Set(ByVal value As Boolean)
        _CountBoxVisible = value
    End Set
End Property

Note the _CountBoxVisible variable is define inside the class as :

Dim _CountBoxVisible as Boolean = True

What I am trying to do is give the user/coder the option to show/utilize the char count feature.  Can make it disappear with textarea1.CharacterCountVisible = False but setting it to true will not make it display.


What am i missing





Category attribute of user control property does not work correctly in categories tab.



I have a User Control (ascx) and a property which a want to display in my categories tab in Visual Studio in the category named "Styles".

[Category("Styles"), DefaultValue(""), Description("The value for formating something.")]
public String MyFormatProperty
set { /* the code for set */; }
get { /* the code for get */; }

And here is the problem: Actually I do not need a get, because I only have to set the property (write only property). But when I omit the get, the property is displayed in the "Misc" category in the categories tab in Visual Studio. Only when I code the get as well, then the property is displayed correctly in the "Styles" category in the categories tab in Visual Studio.

Does anybody know why? How can I display the category correctly only with set?

Thanks, S.

Around the Horn: Engineer a Distributed System Using .NET Remoting for Process Intensive Analysis


Before the Microsoft .NET Framework, creating a distributed cluster of computers to perform scientific analysis was expensive in terms of hardware, programming and debugging time, and maintenance. You had to purchase expensive servers, spend time debugging network communication, design a distributed system completely different from a system deployed locally, and maintain a melting pot of error handling, data acquisition, networking, and analysis code. In this article, the author shows you how he was able to engineer a distributed computing system in C# to perform analysis of real-world data continuously acquired at high sampling rates, thanks to the .NET Framework.

Remoting: Managing the Lifetime of Remote .NET Objects with Leasing and Sponsorship


Leasing and sponsorship is the solution for managing the lifecycle of a remote object in .NET. Each object has a lease that prevents the local garbage collector from destroying it, and most distributed applications rely upon leasing. There are several ways in which objects and clients can extend the lease, including dedicated sponsor objects. In this article, the author explains leasing, shows how to configure it, and how it relates to the various remoting activation models. He then discusses design guidelines and options, along with their impact on throughput and performance. Additionally, he introduces a helper class used to automate the management of lease sponsors.

Secure It: WS-Security and Remoting Channel Sinks Give Message-Level Security to Your SOAP Packets


As more organizations adopt XML-based Web Services, the need for message-level security has become evident. WS-Security, now supported in the Microsoft .NET Framework, addresses this need. Using the WS-Security framework, developers can implement channel sinks to intercept Remoting messages as they pass through the .NET Remoting infrastructure. The sink can read the message, change it, and pass it along. During this process, the message can be signed for added security. This article explains how to implement a Remoting channel sink that will modify the Remoting message by including a UserName token in the header, then sign the body using the token.

.NET Remoting: Create a Custom Marshaling Implementation Using .NET Remoting and COM Interop


The .NET Framework offers several methods for customizing the presentation of native .NET and COM object types. One such technique, custom marshaling, refers to the notion of specializing object type presentations. There are times, like when a legacy COM component needs to implement a new interface or when you need to make calls across process or machine boundaries, when custom marshaling saves the day. Elements of COM Interop permit the customizing of COM types while .NET Remoting offers the developer the ability to tailor native .NET types. This article examines these techniques.
