You can use the AllowBypassKey property to specify whether or not the SHIFT key is enabled for bypassing the startup properties and the AutoExec macro. For example, you can set the AllowBypassKey property to False to prevent a user from bypassing the startup properties and the AutoExec macro.
Code:
Sub SetBypassProperty()
Const DB_Boolean As Long = 1
ChangeProperty "AllowBypassKey", DB_Boolean, False or True
End Sub
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
Change_Bye:
Exit Function
Change_Err:
If Err = conPropNotFoundError Then ' Property not found.
Set prp = dbs.CreateProperty(strPropName, _
varPropType, varPropValue)
dbs.Properties.Append prp
Resume Next
Else
' Unknown error.
ChangeProperty = False
Resume Change_Bye
End If
End Function
