Writing the VB.NET code to use a connection is usually the easy part of getting a connection to work. Problems often lie not in the code, but rather in a mismatch in the connection parameters between the client (your VB.NET program) and the database server. All appropriate connection parameters must be used and must have correct values. Even experienced database professionals often have problems getting a connection to work the first time. More parameters are available than the ones shown here, but you get the idea. A corollary of Murphy s Law applies to connections: if several things can go wrong, surely one of them will. Your goal is to check both sides of the connection to make sure all of your assumptions are correct and that everything the client program specifies is matched correctly on the server. Often the solution is on the server side. If the SQL Server instance isn t running, the client will be trying to connect to a server that doesn t exist. If Windows Authentication isn t used and the user name and password on the client don t match the name and password of a user authorized to access the SQL Server instance, the connection will be rejected. If the database requested in the connection doesn t exist, an error will occur. If the client s network information doesn t match the server s, the server may not receive the client s connection request, or the server response may not reach the client.

The ExecuteNonQuery method of the command executes SQL statements instead of queries. Let s try it.

his chapter is about message-based processing in local applications. Here you learn how you can intercept calls to objects to route them through IMessageSinks. This routing allows you to create and maintain parts of your application s business logic at the metadata level by using attributes. You also discover why it might be a good idea to do so.

They are based on Microsoft ASP .NET technology, in which code that runs on the server dynamically generates web page output to the browser or client device. They are compatible with any language supported by the .NET common language runtime, including Microsoft Visual Basic, Microsoft Visual C#, Microsoft J#, and Microsoft JScript .NET. They are built on the Microsoft .NET Framework. This provides all the benefits of the framework, including a managed environment, type safety, and inheritance. The web page consists of application code that serves requests by users; to do so, ASP.NET compiles the code into the assemblies. Assemblies are files that contain metadata about the application and have the file extension .dll. After the code is compiled, it is translated into a language-independent and CPU-independent format called Microsoft Intermediate Language (MSIL), also known as Intermediate Language (IL). While running the web site, MSIL runs in the context of the .NET Framework and gets translated into CPU-specific instructions for the processor on the PC running the web application.
