Most MsDos programs used the Enter key to move from one field to the next one. You can easily simulate this behavior by setting the form's KeyPreview property to True and writing this code in the Form_KeyPress event:
Sub Form_KeyPress (KeyAscii As Integer)
If KeyAscii = 13 Then
If TypeOf ActiveControl Is TextBox Then
KeyAscii = 0
This technique works only if there is no command button on the form with its Default property set to True, because in that case the Form_KeyPress would not trap the Enter key.
