Compact and repair Secured Database - 6/1/2006 14:03:12
Hi,
I have a db1.mdb with user-level security. The Secured.mdw is security file. Everytime we need to refer Secured.mdw to open the db1.mdb.
I created another compact.mdb database for compact and repair the db1.mdb at night time.
In the compact.mdb:
I create the form and setup the timer to compact the db1.mdb at the night time.
I used
Public Function CompactAndRepairDB(sSource As String, _
sDestination As String, _
Optional sSecurity As String, _
Optional sUser As String = "Admins", _
Optional sPassword As String, _
Optional lDestinationVersion As Long) As Boolean
Dim sCompactPart1 As String
Dim sCompactPart2 As String
Dim oJet As JRO.JetEngine
On Error GoTo Err_compact
' Put together the provider string for the source database
sCompactPart1 = "Provider=Microsoft.Jet.OLEDB.4.0" & _
";Data Source=" & sSource & _
";User Id=" & sUser & _
";Password=" & sPassword
' If the database has a user-level security file, add the
' details
If sSecurity <> "" Then
sCompactPart1 = sCompactPart1 & _
";Jet OLEDB:System database=" & sSecurity & ";"
End If
' Put together the provider string for the destination
' database
sCompactPart2 = "Provider=Microsoft.Jet.OLEDB.4.0" & _
";Data Source=" & sDestination
' The destination database will end up in the latest version
' of jet, unless a specific version has been requested;
' 1 = Jet 1.0, 2 = Jet 1.1, 3 = Jet 2.x, 4 = Jet 3.x,
' 5 = Jet 4.x etc
If lDestinationVersion <> 0 Then
sCompactPart2 = sCompactPart2 & _
";Jet OLEDB:Engine Type=" & lDestinationVersion
End If
' Compact and repair the database
Set oJet = New JRO.JetEngine
oJet.CompactDatabase sCompactPart1, sCompactPart2
Set oJet = Nothing
CompactAndRepairDB = True
Exit_compact:
Exit Function
Err_compact:
MsgBox Err.Description
Resume Exit_compact
End Function
Function CompactWithSecurity()
Call CompactAndRepairDB("c:\db1.mdb", "c:\tmp.mdb", "c:\Secured.mdw", "jim")
End Function
It works, because jim is Adminstrator.
But, if Jim is not Adminstrator, then it doesn't work.
if jim is assigned "Backup Operators" and "Read-Only Users" permission by Adminstrator. When Jim logged in the Account, Jim can compact the database from clicking option menu (Database Ulities->Compact and Repair Database...).
If he used compact.mdb database to compact the db1.mdb
with this function
Function CompactWithSecurity()
Call CompactAndRepairDB("c:\db1.mdb", "c:\tmp.mdb", "c:\Secured.mdw", "jim")
End Function
Then it doesn't work.
How can I fix the function?
I want jim to compact the db1.mdb using compact.mdb. But, he is NOT adminstrator. I want to assign limit permission to him to compact the database using compact.mdb file to compact the db1.mdb at the night time.
Thanks.
