Nadya,

Here is code that will only let 5 characters be entered into each line of the edit box. Again ekp is only a variable. It's value needs to be set to zero in the init event of the editbox.

If nKeyCode = 13 Then
If ekp < 4 Then
MessageBox("Must Be five characters")
NoDefault
Else
ekp = 0
EndIf
Else
If ekp = 4 Then
KEYBOARD'{Enter}'
Else
ekp = ekp + 1
EndIf
EndIf
