@fjober

use this in the extbox

Private Sub Text1_KeyPress(KeyAscii as Integer)

If Keyascii = 13 Then
   If Text1.Text = "Exit" Then
       End
   End if
End if

Exit Sub

Search for the keyascii table for different kinds of keys...

[westconn1]

If Text1.Text = "Exit" Then
End
End if

uggh never use end

good morning

thanks for replaying, but I may didn't clear what I want.

I don't want the user to type in a text box or any other field

look at this code:

Private Sub Form_KeyDown(KeyCode As Integer , Shift As Integer)
if KeyCode = vbKeyF Then End
End Sub

as you know, the last program will end it self on pressing F and there are no fields.

I just want it to end on typing exit instead of F

I think this will give you an idea.... You have to play with it to get the perfect one that really suits you...

Option Explicit

Dim strTemp As String

Private Sub Form_KeyDown(KeyCode As Integer, Shift As Integer)
Select Case (KeyCode)
  Case vbKeyE: strTemp = strTemp & "E"
  Case vbKeyX: strTemp = strTemp & "X"
  Case vbKeyI: strTemp = strTemp & "I"
  Case vbKeyT: strTemp = strTemp & "T"
End Select
If strTemp = "EXIT" Then Unload Me
End Sub

Private Sub Form_Load()
strTemp = ""
Me.KeyPreview = True
End Sub

[fjober]

oh my god, this code is really good but....

it would work only if user typed EXIT

what if an error happened while typing? "ECIT" instead of "EXIT" (for example), this means that the program will not continue as I want it because the user cannot undo or delete what he typed.

thanks

Private Sub Form_KeyDown(KeyCode As Integer, Shift As Integer)
Select Case (KeyCode)
  Case vbKeyE: strTemp = strTemp & "E"
  Case vbKeyX: strTemp = strTemp & "X"
  Case vbKeyI: strTemp = strTemp & "I"
  Case vbKeyT: strTemp = strTemp & "T"
  case else: strtemp = ""
End Select

If strTemp = "EXIT" Then Unload Me
   select case strtemp   ' clear any invalid strings
       case "E", "EX", "EXI", EXIT"
       case else : strtemp = ""
   end select
End Sub

or

Private Sub Form_KeyDown(KeyCode As Integer, Shift As Integer)

  if keycode = vbKeyE and strTemp = "" then strTemp = "E"
  if keycade = vbKeyX and strtemp = "E" then strTemp = strTemp & "X"
  if keycode = vbKeyI and strtemp = "EX" then strTemp = strTemp & "I"
  if keycode = vbKeyT and strTemp = "EXI" then strtemp = strTemp & "T"
  

If strTemp = "EXIT" Then Unload Me
End Sub

Or:

Private Sub Form_KeyDown(KeyCode As Integer, Shift As Integer)
    Static n As Long
    Select Case KeyCode
        Case vbKeyE: n = -(n = 0) * 1
        Case vbKeyX: n = -(n = 1) * 2
        Case vbKeyI: n = -(n = 2) * 3
        Case vbKeyT: If n = 3 Then Unload Me else n = 0
    End Select
End Sub

hello everybody

thanks for your help and your ideas

I have wrote a code that do what I want, the most important thing in this code that you can undo what you have typed, here it is:

Private Sub Form_KeyDown(KeyCode As Integer, Shift As Integer)
str = str & Chr(KeyCode)
If LCase(str) = "exit" Then End
If KeyCode = vbKeyZ Then str = ""
End Sub

[akhileshbc]

If LCase(str) = "exit" Then End

A suggestion: Rather than using End, you can use Unload Me ...
