'說明：這是我第一次編寫應用類，其中不當之處請多多指教！QQ：1168064
'屬性和方法
'1、ScanType：掃描的類型。默認值：1。值：0 掃描文件和數據庫 1 掃描文件 2 掃描數據庫。
'2、Conn,Table,ColImg,ColID：當掃描數據庫時用到，分別為連接字符串、表名、圖片列名、圖片對應的ID列名
'3、List：顯示類型。默認值：0。值：0 失效圖片 1 網絡圖片  2 有效圖片 3 所有
'4、ScanText：掃描的圖片類型。默認值：asp/html/htm。值：文件擴展名，中間用"/"分隔。
'5、Path：掃描的路徑：默認為網站根目錄，請使用相對路徑。例如"/dsj"
'6、Scan()：方法。根據設置進行掃描
'7、File：保存掃描的所以信息。在Scan()方法后調用
'8、Folders：掃描的文件夾個數
'9、Files：掃描的文件數。
'10、TotalSize：目錄的總計大小。自動顯示G，M，B。
'11、Images：掃描文件中的圖片個數
'12、Exists：失效個數
'13、DbImg：數據庫中圖片個數
'14、TotalImg：掃描的所以圖片個數
'15、RunTime：掃描過程的時間。單位毫秒
'16、關于File的使用：
'    For Each Fn In ObjName.file …… Next
'    Fn.FileName：圖片名稱，包含路徑
'    Fn.Belong：圖片所在文件或數據庫（文件用"|"分開）
'    Fn.Exists：是否有效。0為失效 1 為有效 -1為非本地路徑，不能判斷。
