expression   A variable that represents an Application object.


NameRequired/OptionalData TypeDescription
SourceFileRequiredStringThe full path and filename of the database or project file to compact and repair.
DestinationFileRequiredStringThe full path and filename for where the recovered file will be saved.
LogFileOptionalBooleanTrue if a log file is created in the destination directory to record any corruption detected in the source file. A log file is only created if corruption is detected in the source file. If LogFile is False or omitted, no log file is created, even if corruption is detected in the source file.

Return Value


The source file must not be the current database or be open by any other user, since calling this method will open the file exclusively.


The following example compacts and repairs a database, creates a log if there's any corruption in the source file, and returns a Boolean value based on whether the recovery was successful. For the example to work, you must pass it the paths and file names of the source and destination files.

Visual Basic for Applications
Function RepairDatabase(strSource As String, _
        strDestination As String) As Boolean
        ' Input values: the paths and file names of
        ' the source and destination files.

    ' Trap for errors.
    On Error GoTo error_handler

    ' Compact and repair the database. Use the return value of
    ' the CompactRepair method to determine if the file was
    ' successfully compacted.
    RepairDatabase = _
        Application.CompactRepair( _
        LogFile:=True, _
        SourceFile:=strSource, _

    ' Reset the error trap and exit the function.
    On Error GoTo 0
    Exit Function

' Return False if an error occurs.
    RepairDatabase = False

End Function
