Abstract:

This article deals only with connecting to databases on a SQL2000 server. Various connection options are discussed and their implementation details are shown. Data retrieval and data manipulation will be discussed in a future article. Only very simple, but basic code to test the connection is used, and each case uses a different ASPX page. This article is self-contained and complete, a copy of the projects in zip format is provided for download.
