Exchange 2000 WSS: Web Storage System Improves Exchange Data Accessibility

Posted By:      Posted Date: August 21, 2010    Points: 0   Category :ASP.Net

The Web Storage System (WSS) in Exchange 2000 is a Web-accessible database that stores any type of data such as e-mail, contacts, appointments, threaded discussions, and multimedia files, and renders the data in HTML in any browser. WSS is based on Internet standards, therefore data can be accessed through URLs, an Exchange OLE DB provider, drive mapping, XML, and Web Documenting and Versioning (WebDAV). This article discusses the WSS schema and how to extend the default schema for custom data. A sample application that uses a custom schema and a custom form to display WSS data is available for download.

Exchange 2000: Web Storage System, Workflow Tools, and CDO Turbocharge Collaboration Apps


Microsoft Exchange 2000, the upcoming version of Exchange Server for Windows 2000, provides many new features including integration with Active Directory, Web Storage System events and forms, and a new version of Collaboration Data Objects (CDO). Exchange 2000 also provides a workflow engine and design tool to create workflow applications. This article will give you an overview of these new features and looks at ways to do a few standard tasks with the new version of CDO. Also included is a sample workflow application that manages the posting of messages to a public server to illustrate the new workflow engine and workflow design tool.

Trustworthy Code: Exchange Data More Securely with XML Signatures and Encryption


You can sign any kind of data using XML Signature, including part of an XML document, other XML documents, or other data of any format. However, in practice, XML signatures are most frequently used to sign other data represented in XML. In this article, the authors discuss the new standard and how you can benefit from it in your apps.

Collaboration Data Objects: Send Microsoft Exchange Appointment Reminders to Your Pager Using CDO


Besides your typical e-mail services, Microsoft Exchange also provides the service infrastructure you need to build extensible knowledge and workflow management systems. Understanding Collaboration Data Objects (CDO) is the key to accessing these Exchange services for your own programs. With CDO you can automate tedious tasks and integrate information such as e-mail, calendars, and contacts with almost any application. This article explains how CDO enables you to access Exchange services, then walks you through a sample application that reads calendar events from an Exchange server and sends pager reminders to your users.

data exchange between server an mobile device



I have a huge problem with the data exchange of a server database and a mobile database( sdf ). At first I load the data with a normal select from the server to my DataSet and then i set the table rows to added and use the DataTableAdapter.Update() command to fill the mobile database.

The problem appears if I do it a second time because I get an exception with a primary key violation. Before i fill my mobile db I delete the whole table with the delete-command.

Why do i get such an exception if no data is in my mobile database??

Kind regards, thomas

The type 'System.Data.Linq.DataContext' is defined in an assembly that is not referenced. You must



This is frustrating, and I don't know how to solve it.

I have a strange problem. I am adding a LinqDatasource object, and set the context:

        protected void LinqDataSource_ContextCreating(object sender, LinqDataSourceContextEventArgs e)
            e.ObjectInstance = new KaruselaDataContext(ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString);

Then I get this error:
The type 'System.Data.Linq.DataContext' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Data.Linq, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089'.


On web.config I already have this:
<add assembly="System.Data.Linq, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089"/>

NOTE: The datacontext is in a different project (DLL proect) where I added a refernce to System.Data.Linq.

is there another way adding a refernce to a web project? or only though teh web.config?

Data Points: XML Features in SQL Server 2000


SQL ServerT 2000 includes several XML features that let you transform relational rowsets into hierarchical XML documents, read XML documents, and bulk load data via XML. For example, you can pass an XML document to a stored procedure, join the XML to some tables and return a rowset, or even modify data in the database.

Code Name WinFS: Revolutionary File Storage System Lets Users Search and Manage Files Based on Conte


One of the monumental problems organizations face today is aggregating information that's stored in disparate formats. Knowledge workers have long wanted to be able to search for content independent of format. The next version of the Windows operating system, code-named "Longhorn," boasts a new storage subsystem that makes that task easier. That subsystem, code-named "WinFS," allows the user to perform searches based on the metadata of the stored item, regardless of what type of file it is or which application created it. This article covers the basic architecture of WinFS and explains how to use the WinFS managed API.

Metadata: Create a Database Schema Repository with Meta Data Services in SQL Server 2000


SQL Server 2000 Meta Data Services is a repository technology that stores and manages metadata for SQL Server. Instead of building database schemas over and over, Meta Data Services allows you to freeze an entire schema for use in other projects. You can also use these schemas for training, testing, or debugging. In this article, the authors will review the various components of Meta Data Services and show how it can be programmed using a Visual Basic client, XML, and XSLT. They will also show you how to manage and manipulate your metadata by generating a simple database schema using a SQL Server repository.

Scripting SQL: VBScript Interfaces in SQL Server 2000 Let You Transform Data and Provide Reports to


Application service providers often must send information to clients automatically rather than on-demand. For example, a manufacturer may want to know each day how many of their products were sold by a retail chain. While SQL Server is ideal for maintaining this type of database, you have to write scripts to get the data out in a client-friendly format. Here you will see how you can use Data Transformation Services (DTS), a powerful tool in SQL Server, to automate the retrieval and formatting of data from SQL Server 2000 and make the process of pushing data to your users a lot easier.

SQLXML 3.0: Build Data-Driven Web Services with Updated XML Support for SQL Server 2000


XML is becoming the ubiquitous data format on the Web, and XML support in SQL Server is evolving to meet the additional demand. Using XML, SOAP, HTTP, and SQL Server, you can now build powerful Web Services easily. To show just how simple it is with SQLXML 3.0, this article walks the reader through the process step by step, from setting up a virtual directory enabling data access via HTTP to executing queries and building Web Services. Finally, the author illustrates the creation of two Web Services clients-one with C# that works with the Microsoft .NET Framework and one with the SOAP Toolkit 2.0 for anyone still using earlier development tools.

SQL and Outlook: Enable Database Access and Updates Through Exchange and Any E-mail Client


Using Microsoft technologies, you can insert, edit, query, and delete database entries using any e-mail client such as Hotmail, Outlook, Yahoo, or even WAP phone. While e-mail is certainly a powerful and widely used tool, it is usually not integrated with an application for performing any tasks other than sending reminders. The application scenario described here, an e-mail-based SQL update program, uses a simple data model; however, this solution will apply to any data model that you are working with. It will also eliminate the need for complex n-tier Internet applications and serves as a low maintenance solution for providing data access.

SQL Server 2000 and XML: Developing XML-Enabled Data Solutions for the Web


Using XML for data access allows you to separate the data from the presentation, and promotes reuse, extensibility, and division of labor. XML also has a simplified data model, which promotes easier testing. This article presents and compares five data access approaches, using a variety of technologies including ASP and ADO, XSLT, and DirectXML. Once built, the solutions are compared on the basis of their speed and efficiency.
