Dim cn As New ADODB.Connection

cn.ConnectionString = "provider=SQLOLEDB;server=(local);uid=sa;pwd="

cn.CursorLocation = adUseClient

cn.Open

cn.Execute "BACKUP DATABASE bak TO DISK = 'c:\mssql7\backup\bak.bak'"

MsgBox "备份成功!"

cn.Execute "RESTORE DATABASE bak FROM DISK = 'c:\mssql7\backup\bak.bak' with replace"

MsgBox "恢复成功!"

cn.Close: Set cn = Nothing
我用上面的语句做备份成功了，可是做还原的时候，vb报错说“因为数据库正在使用，所以未能获得对数据库的排它访问权”怎么解决啊？高手帮忙啊!!!!
