Disable Shift Key

Hello Everyone, I am a database used both in Access 2003 & 2007, Is there a way to disable a user from pressing the Shift key or the PF11 Key and gain access to the Tables?

Here is a link with a sample database that has everything you need ... allows you to enable and disable - from another MDB ... to a target mdb:


Scroll down to 'By Pass Shift Key Code'

Another good link:



To prevent a user bypassing the start-up options you will need to apply the following function and code to a command button (or ideally a hidden option, such as to the double-click event of a label or graphic).

This will prevent anyone without the password bypassing the start-up by using the Shift key.

The below function and command button code will allow you to use a password protected input box to determine if the Shift key can be disabled or not.

You might have to set your "References" in the VBA editor to DAO 3.6.

When you are viewing a Module, click the Tools menu » References. Browse for Microsoft DAO 3.6

Select "Files of type: Executable Files (*.exe; *.dll)"

C:\Program Files\Common Files\Microsoft Shared\DAO)

Then explicitly dimension yourcode, i.e. Dim db As DAO.Database, prp As DAO.Property

'***************** Code Start ***************
'Copy this function into a new public module.

Option Compare Database
Option Explicit

Public Function SetProperties(strPropName As String, _
varPropType As Variant, varPropValue As Variant) As Integer

    On Error GoTo Err_SetProperties

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

    Set db = CurrentDb
    db.Properties(strPropName) = varPropValue
    SetProperties = True
    Set db = Nothing

    Exit Function

    If Err = 3270 Then    'Property not found
        Set prp = db.CreateProperty(strPropName, varPropType, varPropValue)
        db.Properties.Append prp
        Resume Next
        SetProperties = False
        MsgBox "SetProperties", Err.Number, Err.Description
        Resume Exit_SetProperties
    End If
End Function
'***************** Code End ***************
Once you have created the module, then you will need to attach the following code to a command button (or label, graphic etc.):

'***************** Code Start ***************
'Assign this to the OnClick event of a command button (or double-click event
'of a label or graphic) named "bDisableBypassKey"
'Change the "TypeYourBypassPasswordHere" default password to your password

Private Sub bDisableBypassKey_Click()
    On Error GoTo Err_bDisableBypassKey_Click
    'This ensures the user is the programmer needing to disable the Bypass Key
    Dim strInput As String
    Dim strMsg As String
    strMsg = "Do you want to enable the Bypass Key?" & vbCrLf & vbLf & _
             "Please key the programmer's password to enable the Bypass Key."
    strInput = InputBox(Prompt:=strMsg, title:="Disable Bypass Key Password")
    If strInput = "TypeYourBypassPasswordHere" Then
        SetProperties "AllowBypassKey", dbBoolean, True
        MsgBox "The Bypass Key has been enabled." & vbCrLf & vbLf & _
               "The Shift key will allow the users to bypass the startup & _
               options the next time the database is opened.", _
               vbInformation, "Set Startup Properties"
        SetProperties "AllowBypassKey", dbBoolean, False
        MsgBox "Incorrect ''AllowBypassKey'' Password!" & vbCrLf & vbLf & _
               "The Bypass Key was disabled." & vbCrLf & vbLf & _
               "The Shift key will NOT allow the users to bypass the & _
               startup options the next time the database is opened.", _
               vbCritical, "Invalid Password"
        Exit Sub
    End If
    Exit Sub
    MsgBox "bDisableBypassKey_Click", Err.Number, Err.Description
    Resume Exit_bDisableBypassKey_Click
End Sub
'***************** Code End ***************Once this is in place, a user will not have access to bypass the Start-Up options.

As the administrator, you can then click on your command button, label or graphic and will be presented with a input box prompt to enter the bypass password: Please key the programmer's password to enable the Bypass Key.

If the correct password is entered you will see a message: The Shift key will allow the users to bypass the startup  options the next time the database is opened. 

An inncorrect password will give the following message and not allow the Shift key to bypass the Start-Up options: The Bypass Key was disabled. 
The Shift key will NOT allow the users to bypass the  startup options the next time the database is opened. 

Note: Always create a backup copy of the database, to test out any areas that may cause problems when working with start-up options or disabling Access features.

1. Create a new module and past this code inside it:

Option Compare Database
Option Explicit

Function ChangeProperty(strPropName As String, varPropType As Variant, varPropValue As Variant) As Integer
   Dim dbs As Object, prp As Variant
   Const conPropNotFoundError = 3270

   Set dbs = CurrentDb
   On Error GoTo Change_Err
   dbs.Properties(strPropName) = varPropValue
   ChangeProperty = True

   Exit Function

   If Err = conPropNotFoundError Then    ' Property not found.
       Set prp = dbs.CreateProperty(strPropName, _
           varPropType, varPropValue)
       dbs.Properties.Append prp
       Resume Next
       ' Unknown error.
       ChangeProperty = False
       Resume Change_Bye
   End If
End Function

Function BypassKey(onoff As Boolean)
   Const DB_Boolean As Long = 1
   ChangeProperty "AllowBypassKey", DB_Boolean, onoff
End Function
'-----------------------------------------------------------------------Then save the module to whatever you like.

2. Create the macros.
2.1 Macro Name: ByPassKeyOff
Action: Runcode
Function: BypassKey(False)
2.2 Macro Name: ByPassKeyOn
Action: Runcode
Function: BypassKey(True)

3. On your switchboard or logon screen create a rectangle with the same backcolor as the form and no border. Remember where it is. Or if you have a picture you can use it aswell. On the properties of the rectangle or picture select the Event tab->OnClick. Use the picker to select the ByPassKeyOn macro.

4. Run the ByPassKeyOff macro. Save and close the db.

5 Now when you start up and hold the shift key the db window will not show. To allow the shift key click where you put your rectangle or click the picture and close the db. Re-open with the shift key and the database window will appear. To disable do step 4.

There you go. Just another way to make sure your database is secure.
