Hi,

 Please find the following code

lstAuthors.Items.Add(objItem("Outcome").ToString().Substring(objItem("Outcome").ToString().IndexOf("on", 0) + 2, objItem("Outcome").ToString().IndexOf("has", 0) - 3).Trim());

Hope it will help you..

Hi, 

you can have, 

	private string TextBetween(string text, string startwith, string endwith)
		{
			var startIndex = text.IndexOf(startwith) + startwith.Length;
			var endIndex = text.IndexOf(endwith);
			if (startIndex < endIndex)
			{
				return text.Substring(startIndex, (endIndex - startIndex));
			}
			return text; // or  null
		}

and have a call like, 

var d = TextBetween("Approval Workflow on industrial has successfully completed. All participants have completed their tasks", "on", "has");

you can change same code to VB

I hope this helps you...
