I suggest to use VB.NET's 'Left' function because it is more descriptive
than the string's 'Substring' method.

Agnes,
The Left function in .NET is Microsoft.VisualBasic.Strings.Left!

If you use Strings.Left you may want to use an Import alias on
Microsoft.VisualBasic.

Imports VB = Microsoft.VisualBasic

Dim myString As String
myString = VB.Left(myString, 5)

Especially in Window Forms, as Left is a property of Control.

An alternative to Microsoft.VisualBasic.Strings is the methods on String
itself (such as String.SubString). I normally use String.SubString instead
of Strings.Left, however both are equally valid.

The one caveat I recommend is do not mix the VB Strings functions with the
String methods, as VB Strings are 1 based indexes & the String methods are 0
based indexes.

Hope this helps
Jay
