i have using sql server 2005 express managment studio, i have create my database and every thing just i want to extact Database and attach it to My asp.net 3.5 Project how?

I work with Visual studio 2005 and Sql server data base. I extract 1 million rows from a database and I put the rows in a Sql table. With a simple direct extraction, in a few minutes I complete the operation:
Dim cmd As New SqlCommand(query, cnSql) cmd.ExecuteNonQuery() cmd.Dispose().
But, if I must select and modify some fields between extraction and introduction, it takes a lot of time! I work in this way. I extract rows from Dbase, Table1, and I put all into a Collection using dataReader:
Dim cmd As New SqlCommand(query, cnSql) Dim coll As New Collection coll.Clear() Dim dr As SqlDataReader = cmd.ExecuteReader() I replace some fields with the string "YES". Dim toRepl As String = "" If dr.HasRows Then Do While dr.Read toRepl = dr(5).ToString If Len(toRepl) <= 3 Then ToRepl = "YES" collPrel.Add(dr(0).ToString) collPrel.Add(dr(1).ToString) .................. .............. collPrel.Add(toRepl) collCount = collCount + 1 Loop End If dr.Close() cmd.Dispose() Now, I insert all into a SQL Table2: Dim a As String = "", b As String = "", c As String = "" etc. For i = 1 To collPrel.Count Step 6 a = collPrel.Item(i).ToString b = collPrel.Item(i + 1).ToString .............. ............... f = collPrel.Item(i + 5).ToString queryIns = "INSERT INTO Tab (name, adress, etc) VALUES ('" & a & "', '" & b & "', '" & c & "', etc. ) Dim cmdIns As New SqlCommand(queryIns, cnSql) cmdIns.CommandTimeout = 600 cmdIns.ExecuteNonQuery() cmdIns.Dispose() Next
This way to work goes right but it is necessary a lot of time for completing the operation.
I have a string containing some html-code...Lets say it looks like this:
[Code]....
Now I want to extract only the text from it, no tags etc should be included in my final string....Whats the best way to accomplish this?I want a final string like: myFinalString = "This is a header. Some description-text goes here. Here is a bold text";
