If you need to make it so that the users can't use the shift key even
if they know about it, you can use this code created by Michael
Kaplan.

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 ChangePropertyDdl("AllowBypassKey", dbBoolean, False) Then
MsgBox "Shift key access disabled."
Else
Msgbox "An error occured."
End If
End Sub
Public Sub EnableShiftKey()
If ChangePropertyDdl("AllowBypassKey", 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 conPropNotFoundError = 3270
to
Const conPropNotFoundError = 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("Password:", "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("Password:", "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.
