  • Hi,

    Add one Button

    to a Form and try this example please.>>

    Imports OldVB = Microsoft.VisualBasic
    Public Class Form1
        Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
            Dim exampleString As String = "The quick brown fox."
            Dim leftStr As String = ""
            Dim rightStr As String = ""
            Dim midStr As String = ""
            leftStr = OldVB.Left(exampleString, 9)
            rightStr = OldVB.Right(exampleString, 10)
            midStr = OldVB.Mid(exampleString, 5, 11)
            MessageBox.Show(leftStr, "leftStr = ")
            MessageBox.Show(rightStr, "rightStr = ")
            MessageBox.Show(midStr, "midStr = ")
            'The above are still available for those
            'converting from VB6 and earlier versions.
            'You could use these instead.
            'Note the capital "T" in "The quick brown fox."
            'is at index position zero (0) in the new functions.
            leftStr = exampleString.Substring(0, 9)
            rightStr = exampleString.Substring(exampleString.Length - 10)
            midStr = exampleString.Substring(4, 11)
            MessageBox.Show(leftStr, "leftStr = ")
            MessageBox.Show(rightStr, "rightStr = ")
            MessageBox.Show(midStr, "midStr = ")
        End Sub
    End Class
