Microsoft's Collaborative Application Markup Language (CAML) Loop

Posted By: Rahul     Posted Date: October 13, 2009    Points: 2   Category :.NET Framework
discovered an interesting error recently while working with Microsoft's Collaborative Application Markup Language (CAML) that, surprisingly, had received no ink. Partly what surprises me about this is that the error may require you to rewrite large sections of your code if you haven't previously considered this SharePoint limitation. I'll start with some context, but first of all the error is:

MVC architecture in ASP.Net using C# and Microsoft Data Access Application block

The Model-View-Controller (MVC) pattern separates the modeling of the domain, the presentation, and the actions based on user input into three separate classes [Burbeck92]:

Model. The model manages the behavior and data of the application domain, responds to requests for information about its state (usually from the view), and responds to instructions to change state (usually from the controller).

View. The view manages the display of information.

Controller. The controller interprets the mouse and keyboard inputs from the user, informing the model and/or the view to change as appropriate.

    Microsoft Application Block for Data Access in .NET


    Hi all,

    I was rummaging the internet learning aspx and came across the concept of: Microsoft Application Block for Data Access in .NET

    It seems great of course. The articles are all early 2003-5 such as

    ISA Server 2004: Developing an Application Filter for Microsoft Internet Security and Acceleration S


    The beta version of Internet Security and Acceleration (ISA) Server 2004 is now publicly available. It includes a rich SDK with several extensibility mechanisms that allow third parties to integrate their specialized solutions on top of the ISA platform. In this article, the author explores the application filter extensibility mechanism, which enables you to add high-level application layer filtering capabilities to ISA Server and to provide rich content filtering solutions. He also highlights the new features of the ISA Server 2004 SDK, then moves on to describe how to develop a basic application filter that monitors all data going through the ISA Server, and how to integrate a filter into the ISA Server management console to create a seamless interface experience for your users.

    Wireless Web: Microsoft Mobile Internet Toolkit Lets Your Web Application Target Any Device Anywhere


    If you've built Web sites using ASP.NET, you'll welcome the Microsoft Mobile Internet Toolkit (MMIT). MMIT extends the Visual Studio .NET IDE you already know by providing new controls for handheld devices letting you easily develop applications for wireless devices. This means you can write less code while adapting it to more devices. Not only does MMIT integrate with Visual Studio .NET, it extends ASP.NET as well. This article gives you the background you need to write, test, and deploy a site with MMIT and make all your code able to target specific devices for a custom fit.

    C# and the Web: Writing a Web Client Application with Managed Code in the Microsoft .NET Framework


    When the author wanted to build a middleware Web client to connect to other applications over the Internet, he realized that the XMLHttpRequest COM object was not sufficient for his purposes. In order to build a Web client using managed code, the author had to use the HTTPWebRequest and HTTPWebResponse classes provided by the Microsoft .NET framework. These classes are used in the sample project as a substitute for the less powerful XMLHttpRequest COM object, allowing the author to build a full-featured Web client. They also take advantage of all the benefits that the CLR and managed code have to offer.

    Microsoft .NET: Implement a Custom Common Language Runtime Host for Your Managed App


    While most application developers may not need to write a custom host, understanding what is involved provides a great deal of insight into the architecture of the CLR. After covering how the CLR is started and loaded into a process, how to set the available configuration options, and how a host defines application domains, this article explains how to design a custom host. Important concepts include making the right decisions about the application domain boundaries for the host, configuring them correctly, loading and executing user code, and resolving references to assemblies. Setting security policy and unloading application domains as the application shuts down are also explained.

    Avoiding DLL Hell: Introducing Application Metadata in the Microsoft .NET Framework


    The Microsoft .NET platform uses metadata and assemblies to store information about components, enabling cross-language programming and resolving the infamous DLL Hell problem. This article describes the use of metadata for easy linking and loading of assemblies, the relationship between metadata and concepts such as IDL and type libraries, and the metadata hierarchy. The process of reading metadata from assemblies for easy versioning is also described. Although Microsoft provides the MSIL disassembler, IDLASM, and MetaInfo.exe for accessing metadata, the author provides two sample programs that read metadata using the unmanaged metadata interfaces and the Reflection API.

    Upsize Your Database: Convert Your Microsoft Access Application to Take Advantage of SQL Server 7.0


    What if you need to convert an existing Microsoft Access 97 database application into a true client-server application that is based on a SQL Server back end? If you know a little about Visual Basic and SQL Server, it's easy to make your app take advantage of the power and scalability provided by SQL Server 7.0. Using some concrete code examples, this article takes you step by step through converting the native Jet queries in your Access application into stored procedures and pass-through queries that SQL Server can use. You'll also learn how to pass on parameters when your client-server app calls these SQL Server stored procedures and queries.

    Question on Microsoft Enterprise Library 5.0 for a mobile web application



    Our company is in the process of building a new website dedicated for mobile devices.

    Since we are starting from scratch, I would like to consider implementing the Microsoft Patterns & Practices Enterprise Library 5.0 on the site.

    I would like to ask others what they think

    1) Is this too much overhead where speed is mission critical?

    2) Have you implemented this library for a mobile site? If so, why? Please describe your experience.

    3) Given time and resources, would you implement this library?

    I appreciate all feedback



    Language settings in WPF application



    Is there a way to change the keyboard layout for WPF applications according to the selected Region and Language settings of the system?

    To explain more about the problem, please find the scenario below.

    Normally, In English(US) culture, the decimal numbers are seperated by dot(.) seperator. But in Dutch(Netherlands), the decimal numbers are seperated by comma(,) seperator. After changing the Region and Culture settings to Dutch(Netherlands), if you open the excel sheet and type a number with number pad in the keyboard, when we you use dot(.) symbol in the number pad, it will be automatically replaced as comma(,) by the application. How can we achieve the same using our application in C#?

    Thanks in Advance!!!!

    Microsoft Enterprise Library 5.0 - Logging Application Block Activation Error


    Hi folks,

    I've been writing a class where I wanted to write the errors off to the OS EventLog. I was pointed towards the Logging Application Block. I used LogWriter successfully in a web page and transfer the code to the class so that I could have the functionality there.

    I keep getting an {"Activation error occured while trying to get instance of type LogWriter, key \"\""} Error when I reach this line of code:

    private LogWriter writer = EnterpriseLibraryContainer.Current.GetInstance<LogWriter>();

    I had something similar with the daab getinstance call but I added the unity assemblies to the code and this resolved this. I thought this was the issue with this problem.

    Could anyone tell me what I'm doing wrong?

    Thanks in advance folks.

    app.config code:


    <?xml version="1.0" encoding="utf-8" ?>
            <section name="loggingConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Logging.Configuration.LoggingSettings, Microsoft.Practices.EnterpriseLibrary.Logging, Version=5.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" requirePermission="true" />
