Solution 1

String.Trim[^] does both ends
String.TrimStart[^] does the left side only
String.TrimEnd[^] does only the right.

You can optionally provide a list of characters to trim, otherwise it uses just the standard white space characters.

can u give an example of using just a variable? for example a variable holding a text of hello world, and i only want the "ld" to display on a messagebox.. tnx..

Ah! That's different - my mistake.
You want String.Substring:
http://msdn.microsoft.com/en-us/library/system.string.substring.aspx

Dim s As String = "Hello World"
Dim t As String = s.Substring(9)
Or
Dim s As String = "Hello World! This is text!"
Dim t As String = s.Substring(9, 2)
The first param is the zero-based index of the first character to include, and any second parameter is the number of characters to include in the new string.
