Dim id As String = TextBox1.Text 'the last id no is in textbox1. you can get it
from database

Dim number As Integer = id.Substring(2, 4)
If (number < 9) Then
TextBox1.Text = id.Insert(5, (number + 1).ToString()).Remove(6)

ElseIf (number < 99) Then
TextBox1.Text = id.Insert(4, (number + 1).ToString()).Remove(6)
ElseIf (number < 999) Then
TextBox1.Text = id.Insert(3, (number + 1).ToString()).Remove(6)
ElseIf (number < 9999) Then
TextBox1.Text = id.Insert(2, (number + 1).ToString()).Remove(6)

End If
