I am using the following code to compact a database.
If the mdb file has not been opened. ie. This is e 1st thing done when opening the program. It works fine!!
---
 Label1 = "Compacting Databases"
    Label1.Refresh

    Dim Fsys As New FileSystemObject
    Dim OutFile As String
    Dim Infile As String
    Infile = App.Path & "\" & "awol.mdb"
    OutFile = App.Path & "\" & "awolx.mdb"

    If Len(Dir(OutFile)) > 0 Then
        Kill OutFile
    End If
   
    DBEngine.Workspaces(0).Close  

    DBEngine.CompactDatabase Infile, OutFile, ";pwd=admin", , ";pwd=admin"

    If Len(Dir(Infile)) > 0 Then
        Kill Infile
    End If

    Fsys.CopyFile OutFile, Infile, overwrite
------------------------------------------------

BUT...!@!@!@!@ If i have had the mdb file open under ADO, and close the connection , and then try to run the above code, i get an error You attempted to open...allready exclusivery open  etc... error 3356.

If i go totally out of the program, and then come back in, and run the compact, all ok.


How do you TOTALLY  !@@!!@ close a database so i can compact it.

I am opening as follows.

Dim StrDBFileName As String
    Dim StrCnn As String

    StrDBFileName = Trim(App.Path) & "\Awol.mdb"
    StrCnn = "Provider=Microsoft.Jet.OLEDB.4.0;Jet OLEDB:Database Password=admin;Data Source=" & StrDBFileName
    Set cnn = New ADODB.Connection
    cnn.Open StrCnn

Set rs = New ADODB.Recordset
    Set rs2 = New ADODB.Recordset
   
    rs.Open "wol", cnn, adOpenKeyset, adLockOptimistic, adCmdTableDirect
    rs2.Open "wolid", cnn, adOpenKeyset, adLockOptimistic, adCmdTableDirect

----
rs.Close
rs2Close
cnn.Close
                                                                                                                  Set cnn = Nothing
DBEngine.Workspaces(0).Close  

After all these close's, the compact still will not work, an i missing something???

===================================================

Appreciate any help.

DBEngine.Workspaces(0).Close  is DAO not ADO!

I agree an error.
I only included DBEngine.Workspaces(0).Close  , at the last moment in a lapse of brainpower.!! After 2 hours of this thing not working.

Suddenly the whole thing is working.

The only thing i did was go into Access and open the database and then go back out.

Not sure if this has anything to do with it, BUT all is OK now....Hopefully forever!!!

Well, i would like to say a couple of things:
1)Thanks for "A" grade.
2)do you use filesystem only to use in
Fsys.CopyFile OutFile, Infile, overwrite
?
If so, you could use name function or FileCopy one
3)change this:
If Len(Dir$(OutFile)) > 0 Then
    Kill OutFile
End If
to this
If Dir$(OutFile)<>"" Then
    Kill OutFile
End If
I think, why to use one more function where it is not necessary?
;)
Cheers

Appreciate you help.
Did not like to give a "C" grade !!!, even under these circumstances.

I use fsys. for both copying,deleting
Will give filecopy a go, as most of the fsys. is for copying files.
