ASP.Net WebForm, C#, Visual Studio, SQL Server connection My code is something like this... using System; using System.Collections; using System.ComponentModel; using System.Data; using System.Drawing; using System.Data.SqlClient; using System.Web; using System.Web.SessionState; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.UI.HtmlControls; private void PopulateList() { // initialize the Database object Database DataStore = new Database(); SqlDataReader dataReader = null; ... DataStore.RunProc("CODES_SELECT_ALL", out dataReader); while (dataReader.Read()) { ... } } C:\Inetpub\wwwroot\WebApplication1\...): The type or namespace name 'Database' could not be found (are you missing a using directive or an assembly reference?) Any ideas for this rookie?

Hey Guys,
Inorder to use Database class, we need few dll's from microsoft enterprise library.
* Microsoft.Practices.EnterpriseLibrary.Common.dll
* Microsoft.Practices.EnterpriseLibrary.Data.dll
* Microsoft.Practices.ObjectBuilder2.dll
Add the reference of these libraries to your project and you will be able to get rid of the error.
Happy Learning :)

You are correct, benricho. I had copied the code. I rewrote the code to solve this issue. Thank you for your response.

Where did you get this line from? Database DataStore = new Database(); Do you have a class called Database? It isn't in any using statement. Could this be copied from some code you saw elsewhere? If so, I would say that the person who wrote the code has used a component with a class called Database which has some basic data access methods in it to make everyday data access a little quicker.
