    disable/enable the shift key

    Hi all,
    First of all I'd like to thank you very very much ,as finally after many years of searching,I could find a code to disable/enable the shift key,but actually i cannot use the code as I'm very new to VBA,i tried to follow the instructions reported in the code,but i got no result,i still can use the shift key,can you explain in details how to use it correctly to enable/disable users from pressing shift key to view database windw?,the code i was talking about is the below
    one:

    'This code was originally written by Michael Kaplan.
    'It is not to be altered or distributed,
    'except as part of an application.
    'You are free to use it in any application,
    'provided the copyright notice is left unchanged.
    '
    'Code Courtesy of
    'Michael Kaplan
    '
    Function ChangePropertyD dl(stPropName As String, _
    PropType As DAO.DataTypeEnu m, vPropVal As Variant) _
    As Boolean
    ' Uses the DDL argument to create a property
    ' that only Admins can change.
    '
    ' Current CreateProperty listing in Access help
    ' is flawed in that anyone who can open the db
    ' can reset properties, such as AllowBypassKey
    '
    On Error GoTo ChangePropertyD dl_Err

    Dim db As DAO.Database
    Dim prp As DAO.Property

    Const conPropNotFound Error = 3270

    Set db = CurrentDb
    ' Assuming the current property was created without
    ' using the DDL argument. Delete it so we can
    ' recreate it properly
    db.Properties.D elete stPropName
    Set prp = db.CreateProper ty(stPropName, _
    PropType, vPropVal, True)
    db.Properties.A ppend prp

    ' If we made it this far, it worked!
    ChangePropertyD dl = True

    ChangePropertyD dl_Exit:
    Set prp = Nothing
    Set db = Nothing
    Exit Function

    ChangePropertyD dl_Err:
    If Err.Number = conPropNotFound Error Then
    ' We can ignore when the prop does not exist
    Resume Next
    End If
    Resume ChangePropertyD dl_Exit
    End Function
    ' *********** Code End ***********

    Paste the above code into a module. Then you can use the following
    procedures to disable and enable the shift key for when you need it.

    Public Sub DisableShiftKey ()
    If ChangePropertyD dl("AllowBypass Key", dbBoolean, False) Then
    MsgBox "Shift key access disabled."
    Else
    Msgbox "An error occured."
    End If
    End Sub

    Public Sub EnableShiftKey( )
    If ChangePropertyD dl("AllowBypass Key", dbBoolean, True) Then
    MsgBox "Shift key access enabled."
    Else
    Msgbox "An error occured."
    End If
    End Sub

    One problem I note in my version of Access 2003. The error number for
    property not in collection seems to be 3265 now, not 3270. If you get
    the an error occured message, change the line:

    Const conPropNotFound Error = 3270
    to
    Const conPropNotFound Error = 3265

    This code will disable the shift key for everyone, including you. Make
    sure that you put a button or give your self some way to run the enable
    code even if you don't have access to the database window. Here's how
    I do it.

    On a form in the database, I almost always have some sort of
    administration functions. I put two buttons on there, one for
    disabling and one for enabling the shift key. If I am using user-level
    security, I just restrict access to that form to only admins.
    Otherwise, you can write a simple piece of code to force a password
    prompt on the two buttons.

    Private Sub cmdDisableShift _Click()
    If MsgBox("Do you want to disable the shift key?", vbYesNo,
    "Confirm") = vbYes Then
    If InputBox("Passw ord:", "Restricted ") = "1234" Then
    DisableShiftKey
    Else
    MsgBox "Incorrect password."
    End If
    Else
    MsgBox "Shift key access is not disabled."
    End If
    End Sub

    Private Sub cmdEnableShift_ Click()
    If MsgBox("Do you want to enable the shift key?", vbYesNo,
    "Confirm") = vbYes Then
    If InputBox("Passw ord:", "Restricted ") = "1234" Then
    EnableShiftKey
    Else
    MsgBox "Incorrect password."
    End If
    Else
    MsgBox "Shift key access is not enabled."
    End If
    End Sub

    Just replace 1234 with whatever password you want to use.

    I have to tell you that disabling the <Shift> key is fraught with peril! Think of all the things you can't do! You couldn't even enter an uppercase character in a textbox! What is the key combination you're trying to prevent? <Shift> + ???
    You talk of "enable/disable users from pressing shift key to view database window" but pressing F11 brings up the database window.

      I think what is trying to be done is stop a user holding down the shift key when they are starting up the database so as to restrict access to the database structure (modify tables, design forms, etc). basically a security feature without having to use the jet database security.

      I would also be intrested in this solution as at the moment i am using /runtime on the end of a shortcut to the database. as shown below.

      "C:\Program Files\Microsoft Office\OFFICE11 \MSACCESS.EXE" "Drive:Path \My Database.mdb" /runtime

      This works to some extent but most people would be able to get round this if they look at the properties of the shortcut and remove the /runtime from the end

        why don't you just create an MDE file then?
