.NET Anatomy – Structured Exception Handling in .NET

This article discusses structured exception handling (SEH), a service built into the core of .NET and available to all languages supported by it. Since the infrastructure for this service is built-in, there is very little code required to take full advantage of these features.

.NET Connector for Microsoft Outlook

.NET Interop: Get Ready for Microsoft .NET by Using Wrappers to Interact with COM-based Applications

Export Microsoft Outlook data using XML DataSets and the Outlook COM Object Library.

Very soon, the development of Microsoft .NET applications will require interaction between those apps and existing COM components on both the client and the server. The .NET Framework has made provisions for this interaction by implementing various wrappers for COM objects to allow exposure of their properties and methods to .NET components. These wrappers will make it easy to make the connection between COM and .NET.

.NET MD5 Class Library

.NET Remoting - The Interface Approach

a MD5 Class Library for .NET supporting advanced features like Random Salt values embedded into the MD5 hash.

C# Help

In this article, we will create a remote object, and access this object using an interface. This method is important when creating a physical separation between business tier and consumer code. In traditional Remoting approaches, to access a remote object, you need a copy of that object on the client machine. With this approach, the metadata is split into a separate library that can be copied to the client machine.

A Portal for My Data

A Remedy for DataGrid Vertigo

With it comes to retrieving data in an n-tier application. We often design our systems in a way that forces us to figure out a different way to get each type of data, calling a different service, object, or method each time. To get customer data, we call the GetCustomer method of the CustomerService. To get product data, we call the Product method of a WebProduct service. This can get confusing!

Accessing Data Using System.OleDb

The AlternatingItemStyle can be a wonderful thing. But in many cases I found that I would start to get a feeling like vertigo if I scrolled the page up or down. So I thought back to my days in Manhattan in the financial industry and remembered how I used to prepare reports to be viewed on screen. I alternated the colors of the rows, but I did it every three or five rows (depending on the width of the report, the content of the report, or my own aesthetic taste).

C# Help

This simple application demonstates several aspects of object-oriented programming in C#. It builds a simple class called "Batters" with several fields and then populates their values by retrieving data from an Access Database. In my research on how to retrieve data using System.OleDb I found that there wasn't any one help file that demonstated how to put it all together. I hope this helps.

Accessing Schemas

C# Corner

OleDb data provider's connection class (OleDbConnection) provides a method GetOleDbSchemaTable that returns a database schema.

Adding Blank Rows to a DataGrid

In this article we will be illustrating one way to add a blank row to a DataGrid. Why would you want to do this? Who knows, maybe to enable a user to add a new record. This article will show you how to add a new row to a DataGrid by manipulating its DataSource - in this example a DataTable. Note that we will be simulating saving the new item back to the database.

Adding Items to a DataView and DataTable

In one application I had the requirement to add a blank row after every 10 rows in a DataGrid rather than use paging. There is no in-built way to do this with the DataGrid, but it can be easily done by modifying the DataTable that the DataGrid is bound to and by writing some code in the DataGrids ItemDataBound event. This how-to article will describe how it is done.

Adding Items to a DataView and DataTable

In this article we'll be demonstrating how to add a new row to both a DataTable and a DataView. In the first part of this article we will briefly discuss the differences between a DataView and DataTable, then we'll give a code example and analysis of how to add a new item to each. The code will demonstrate how effecting one, has a direct effect on the other.
