Hi there,

I believe the solution to your problem can be found here:
How to extract the strings between two characters[^]

It uses a regular expression to find the string and extract it.

Actually i am a newbee to this, and i dont know what does 'REGEX' means , But i noticed that there was a extension posted on this. How to use that? I mean should i just copy paste that into my code and call it later to find the string or something else. Thanks for your reply Smile | :)

That link provides sample code, the term REGEX is an abbreviation of Regular Expression and if you Google the term there are plenty of resources to explain what it is. There is a RegEx class in .Net which stores a regular expression definition which can be used repeatedly or you can take the approach that ProgramFox has detailed in solution 2 where you create it on the fly when you need it.

Solution 2

Hi,

Try this:

VB

label1.Text = System.Text.RegularExpressions.Regex.Match(textBox1.Text, "(?<=#)(.+)(?=#)").Value
' change label1 and textBox1 into the names of your label and text box

Hope this helps.
