网站图片扫描类

  1   
  2'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   
  3'属性和方法   
  4'1、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。   
  5'2、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   
  6'3、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   
  7'4、ScanText：扫描的图片类型。默认值：Asp/html/htm。值：文件扩展名，中间用"/"分隔。   
  8'5、Path：扫描的路径：默认为网站根目录，请使用相对路径。例如"/dsj"   
  9'6、Scan()：方法。根据设置进行扫描   
 10'7、File：保存扫描的所以信息。在Scan()方法后调用   
 11'8、Folders：扫描的文件夹个数   
 12'9、Files：扫描的文件数。   
 13'10、TotalSize：目录的总计大小。自动显示G，M，B。   
 14'11、Images：扫描文件中的图片个数   
 15'12、Exists：失效个数   
 16'13、DbImg：数据库中图片个数   
 17'14、TotalImg：扫描的所以图片个数   
 18'15、RunTime：扫描过程的时间。单位毫秒   
 19'16、关于File的使用：   
 20' For Each Fn In ObjName.file …… Next   
 21' Fn.FileName：图片名称，包含路径   
 22' Fn.Belong：图片所在文件或数据库（文件用"|"分开）   
 23' 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。
