Use The Left() Function In VB 2010?

I have a very small VS 2010 app that basically reads the records of a text file, adds some additional information to the end of the record read, and writes the new record to a new text file.The issue Im having is with the Left() function.I need to take all chars left of position 10 of a text box and add it to the end of the new record before I write it. When I use the Left() the "Error List shows an error related to this function.The error says:Public Property Left As Integer has no parameters and its return type cant be indexed.It gives two solutions: 1) Generate Method Stub Left in Project1.Form1 and 2) Generate Property Stub Left in Project1.Form1 When I select solution

1) that creates a warning indicating: Function Left conflicts with property Left in the base class Control and should be declared Shadows. When I select solution

2) that creates a warning indicating: Property Left shadows an overloadable member declared in the base class 'Control. If you want to overload the base method, this method must be declared 'Overloads.

Here is the code:

Public Class frmProcessFile
Private Sub cmdProcessFile_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles
