'说明：这是我第一次编写应用类，其中不当之处请多多指教！QQ：1168064
'属性和方法
'1、ScanType：扫描的类型。默认值：1。值：0 扫描文件和数据库 1 扫描文件 2 扫描数据库。
'2、Conn,Table,ColImg,ColID：当扫描数据库时用到，分别为连接字符串、表名、图片列名、图片对应的ID列名
'3、List：显示类型。默认值：0。值：0 失效图片 1 网络图片 2 有效图片 3 所有
'4、ScanText：扫描的图片类型。默认值：Asp/html/htm。值：文件扩展名，中间用"http://www.cuoxin.com/"分隔。
'5、Path：扫描的路径：默认为网站根目录，请使用相对路径。例如"/dsj"
'6、Scan()：方法。根据设置进行扫描
'7、File：保存扫描的所以信息。在Scan()方法后调用
'8、Folders：扫描的文件夹个数
'9、Files：扫描的文件数。
'10、TotalSize：目录的总计大小。自动显示G，M，B。
'11、Images：扫描文件中的图片个数
'12、Exists：失效个数
'13、DbImg：数据库中图片个数
'14、TotalImg：扫描的所以图片个数
'15、RunTime：扫描过程的时间。单位毫秒
'16、关于File的使用：
' For Each Fn In ObjName.file …… Next
' Fn.FileName：图片名称，包含路径
' Fn.Belong：图片所在文件或数据库（文件用"|"分开）
' Fn.Exists：是否有效。0为失效 1 为有效 -1为非本地路径，不能判断。
