Delete access .mdb problem
Hi,
In deleting .mdb file, I found that sometimes error occur:
permission denied
Is it because I have a corresponding .ldb file that keep some resources that the .mdb file is not allowed to delete?
I have tried to wait until it disappear after I disconnect the database.
If Dir(App.path & "\Database\" & appFileName & ".ldb") <> "" Then
Do While True
MsgBox "xx.ldb fading out..."
DoEvents: Sleep 5000
If Dir(App.path & "\Database\" & appFileName & ".ldb") = "" Then Exit Do
Loop
But the .ldb never disappear!
What can i do?
1.Is my deduction correct, or is there any other points I have missed out?
2. And can first delete the .ldb file and then .mdb file? Please give me a sound solution ....
Thanks!

it sounds like you have an open connection to the database.Are you connecting to it from VB? Make sure you close the connection and set it to Nothing
ASKER
Can I just set it to nothing?
Does it mean already that the conn has been closed?

you could check it to see if it is Closed and set to Nothing:
If Not conn Is Nothing Then
If conn.State <> adStateClosed Then conn.Close
Set conn = Nothing
End If
you could also do the same for your recordsets.
If Not conn Is Nothing Then
If conn.State <> adStateClosed Then conn.Close
Set conn = Nothing
End If

The ldb element is the msaccess locking file. It will just reappear and dissapear.
The DBengine is the problem. It caches updated data and may not release the db until it has completed.
You should try the following
Assuming your object is mydb
mydb.close
set mydb=nothing
set dbengine=nothing
dbengine intialises when your app starts and does not close until your app closes
If it still persists you could try using another application to delete the db
x=shell("killer.app.exe",1

A further thought
Are you using XP Office Pro across server 2000
If so there is currently an issue with all Office products causing locking contentions which could prevent you from deleting your db.

Yes,but aren't you assuming that DAO is being used rather than ADO?
In case the connectoin with the VB program has been closed and the problem still persists, I hope that the file is not read-only!

u should close MDB file
if it's opened from acces u should close this access file
in this sub i want to compact access mdb file then delete old file and rename the new generated file to the old file name :
Sub CompactDB()
Dim DbName As String
DbName = Db2.Name
Db2.Close ' here i close the database
Caption = "Compacting"
Dim X As String, DbFile As String, Dbpath As String
Dim pos As Long
X = DbName
pos = InStrRev(X, "\")
DbFile = Mid(X, pos + 1, Len(X))
Dbpath = Mid(X, 1, pos)
X = Dbpath & "XX" & DbFile
DBEngine.CompactDatabase DbName, X
Kill DbName
Name X As DbName
' here i re open the file
Set Db2 = DBEngine.OpenDatabase(App.
End Sub

Set Db2 = DBEngine.OpenDatabase(App.
