How to programmatically convert multiple Access databases in Access 2002

This article has been archived. It is offered "as is" and will no longer be updated.
Advanced: Requires expert coding, interoperability, and multiuser skills.

This article applies only to a Microsoft Access database (.mdb).

Summary
This article shows you two methods that you can use to programmatically convert Microsoft Access databases. The first method uses the ConvertAccessProject method to convert databases to the format that you specify. The second method uses the Shell function to run Msaccess.exe with the /convert switch. This second method is embedded in a comment block in the sample code. When you use the second method, the databases will be converted to Access 2000 file format regardless of the Default File Format that is specified in the Options dialog box on the Tools menu.

  1. Open a new or an existing database.
  2. On the Insert menu, click Module. Type the following line in the Declarations section if it is not already there:
    Option Explicit					
  3. Type or paste the following procedure:
     Sub ConvertDb(oldDbPath As String, newDbPath As String)'NOTE: Uncomment the line Dim x if you are using the 'alternative Shell function method listed later in this code.'Dim xDim strDBName As StringDim strOLDDB As StringDim strNewDb As StringstrDBName = Dir(oldDbPath & "\*.MDB")   ' Retrieve the first MDB file entry.'Loop though the files in the folder to find MDB files.Do While strDBName <> ""' Ignore the current folder and the encompassing folder.  If strDBName <> "." And strDBName <> ".." Then            If Right(strDBName, 3) = "mdb" Then       strOLDDB = oldDbPath & "\" & strDBName       strNewDb = newDbPath & "\" & strDBName       'NOTE: Comment out the following four lines if you are using the       'Shell function method.       Application.ConvertAccessProject _       SourceFilename:=strOLDDB, _       DestinationFilename:=strNewDb, _       DestinationFileFormat:=acFileFormatAccess2000       'NOTE: The alternative method is to use the Shell function to open       'Access and concatenate the Convert switch instead of using the       'ConvertAccessProject method. To use this method, uncomment the        'following two lines.              ' x = Shell("C:\Program Files\Microsoft Office\Office10\MSACCESS.EXE " & Chr(34) _       '      & strOLDDB & Chr(34) & " /Convert " & Chr(34) & strNewDb & Chr(34))       MsgBox "Conversion complete."    End If  End IfstrDBName = Dir    ' Get next MDB.LoopEnd Sub					
  4. To test this function, create two folders in the root directory of drive C. Name the folders DatabasesToConvert and ConvertedDatabases. Put the databases that you want to convert in the DatabasesToConvert folder, type the following line in the Immediate window, and then press ENTER:
    call ConvertDb("C:\DatabasesToConvert", "C:\ConvertedDatabases")
