I am using Visual Studio 2010. I want to do database connectivity using VB.Net and MS SQL Server 2005. I know 1 way of doing this. Following are the steps...
1. Create a new Data Source Using Data Sources Window. 2. Select the appropriate view like details view/ data grid view for that data source 3. Drag that data source on your form and connectivity is done. Also all the controls are created by the visual studio.
This feature is really cool but I want to learn database connectivity by pure coding without using such advanced features. Also is it possible to do connectivity from a class library ?
