  just tried it but get: an error that:
  "length is not a member of System.Windows.Forms.Form"
  
  

  Private Sub TextBoxZichtrekening1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBoxZichtrekening1.TextChanged

  'TextBoxZichtrekening1.Length = 3

  If TextBoxZichtrekening1.Length = TextBoxZichtrekening1.MaxLength Then

  TextBoxZichtrekening2.Focus()

  End If

  End Sub
  
  am I doing something wrong
  
  thanks again,
  
  Chris

  You can handle TextChanged event of the TextBox, and compare its Text.Length to MaxLength. If it is true, you can call SelectNextControl to move the focus.
  
  You need try a little bit to see whether it is the behavior you want.
  
  Since you could have many TextBoxes like this on your form.  You can create your own TextBox class, which inherits from the standard TextBox, so you won't dup that code.

  HI Chris, you are really close on this one. Here is a sample that does what you want.
  
  
  

  Private Sub TextBox1_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged

  TextBox1.MaxLength = 10

  If TextBox1.Text.Length = TextBox1.MaxLength Then

  TextBox2.Focus()

  End If

  End Sub
  
  The length property for the Textbox is for the Length of the TEXT in the textbox.
  that is where your problem is.
  The sample I included uses only two textboxes. If you have several on the form, the Tab Order could effect this code. ( I haven't tested it to see)

  Thanks Lifeeng,
  
  but I'm really new - (and not very good - but I'm trying)
  this is what I've written so far:
  
  

  Private Sub TextBoxZichtrekening1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBoxZichtrekening1.TextChanged

  TextBoxZichtrekening1.MaxLength = 3

  If TextBoxZichtrekening1.MaxLength Then

  TextBoxZichtrekening2.Focus()

  End If
  
  End Sub
  
  but it goes to the next tab after one number is entered not three
  
  Sorry, if I'm being dumb
  
  can you help
  
  Thanks again.

  Change your "if textboxzl...MaxLength Then" to "if TextBox...Length = TextBox..MaxLength Then".
