Time to have a look at some ADO.NET stuff. In this article we will see how easy it is, to create a simple DataGrid control and bind it to a DataSet object. No more "While not rstProducts.EOF….Wend" statements anymore to list your recordsets! Also, we will have a look at how code behind works. Note that code behind itself has nothing to do with the CodeBehind attribute in the @Page directive, which is only used by Visual Studio .NET....

Accessing data with ADO.NET is usually straight forward. However, once the data we receive is stored in a DataTable, we may begin to feel the limitations of the API when real-world scenarios demand more than the built-in features. One such case is when we need to get the distinct values of an already populated DataTable (or DataView)....

Most data access technologies provide a way for you to query the schema of a database, and obtain information about the tables, stored procedures, data types, users, and other content of a database. However, the technique varies depending on the data provider or database driver you are using and is not always straightforward to implement. In ADO.NET 2.0, Microsoft has added a set of features to the standard managed code classes that you can use as an API to query database schemas. This article l...

To write effective .NET data-driven applications, a deep understanding of the ADO.NET object model is essential. In version 2.0 of the .NET Framework, the set of classes that form the ADO.NET object model are nearly identical to those in version 1.1, but Microsoft has introduced a few key changes. This article examines what's new in the ADO.NET 2.0 classes for database developers. Most of the enhancements fall in two main areas: .NET provider model and SQL Server managed provider. Some of the ne...

With a little preparation on the Excel side and very little work on the ADO.NET side you can connect to and read Excel workbooks just as though they were database tables.
Since Excel has an OleDB provider, we can use ADO.NET's OleDb functionality to connect to Excel. It does take a little preparation on the Excel side however. You might think that since Excel has rows and columns we might be able to use that and refer to A1 and B3, etc. We can't (as far as I know). We must resort to another ...

In this article, we are going to build a Distributed Component to illustrate ADO.NET's disconnected operation facility - the DataSet.The DataSet facilitates the client to manipulate and update a local copy of any number of related tables while still disconnected from the data source and submit the modified data back for processing using a related data adapter at a later point in time. As a result, all our data is going to be maintained on the server in an XML datastore (or flat-file) until chang...

What .NET 2.0 Has in Store for ADO.NET

The article basically demonstrates the use of the factory design pattern to decide at runtime which specific instances of database-related objects to create. It was a necessary evil for those of us unfortunate enough to have to move between different databases such as SQL Server and Oracle and not wanting to produce a bunch of provider-specific code in case the database changed . The factory determines the concrete connection, command, and other objects to create based on the database being acce...

The Windows Forms DataGrid control provides a user interface to ADO.NET datasets, displays ADO.NET tabular data in a scrollable grid, and allows for updates to the data source. In cases where the DataGrid is bound to a data source with a single table containing no relationships, the data appears in simple rows and columns, as in a spreadsheet.As soon as the DataGrid control is set to a valid data source, the control is automatically populated, by creating columns and rows based on the structure ...
