Q:I am able to get the text in a textbox, but now I want to get the data from title, description, etc. to multiple textboxes like

Answer 1

Your best bet would be to use regular expressions to break the string apart and parse it into the invidual fields you desire -- You don't have to use regular expressions, as you could use .NETs native string manipulations (such as SubString, etc) but Regular Expressions are much more flexible and powerful.

I would recommend this thread for a primer on regular expressions: Learning Regular Expressions

I can't vouch for RegEx Buddy which they mention in the thread, but I have indeed found Expresso VERY handy in working out expressions. It is free and available at: http://www.ultrapico.com/Expresso.htm

Example using .NET string methods:

Dim Title As String = TextBox1.Text.Substring(TextBox1.Text.IndexOf("Title:") + 6, TextBox1.Text.IndexOf("Description:") - 6).Trim()

(Really Simple) Example using Regular Expressions (make sure to Import System.Text.RegularExpressions)

Dim Description As String = Regex.Split(TextBox1.Text, "Description:", RegexOptions.Multiline And RegexOptions.IgnoreCase)(1).Trim
