Way To Get All User Result From SQL Query Using For Loop?
Nov 5, 2011

Code:
Dim constguser As New SqlConnection
constguser.ConnectionString = ConfigurationManager.ConnectionStrings("xxxxxxxx").ToString
Dim email1D, email2D, userNickName, userName, rc As String
constguser.Open()

If i run this code its only going to get the name and email of the first result found. I was wondering if there is a faster way to get all user result from the sql query, myb using a for loop?

so ,the new value of [qty] will be the "old valus"+"valus in textbox2"
List<string> IDs = new List<string>(); XDocument doc = XDocument.Parse(xmlFile); var query = from c in doc.Root.Elements("a").Elements("b") select new { ID = c.Element("val").Value};
