Also note this from the help files:
If used in a Windows Forms application, or any other class that has a Left property, you must fully qualify the function with Microsoft.VisualBasic.Left.

You could also use the following
s = txtBox.Text.Substring(0, 3)

Dim TextToFind  as string, S as string
TextToFind = "DEUX"
Dim position as integer
position = InStr(textbox.text, TextToFind  )
Dim numofcharacters as integer
numofcharacters =3
If position >0 then
S = textbox.text.substring(position, numofcharacters)
End if
