『壹』 怎麼用ASP.NET做一個相冊管理系統呢
QQ相冊那個有點難度的特別是上傳圖片選擇那個地方可以和本地直接顯示點了上傳專。。我試了很多次都沒有弄出屬來。
相冊其實就是一個頁面 他的圖案是就是一個按鈕
批量上傳圖片並且預覽這個我到是由源碼。要的話留下郵箱把分給我我就給你傳($ _ $)
『貳』 圖片上傳的ASP源代碼
4個文件實現無組件上傳4個文件實現無組件上傳
嵌套式調用：
<iframe name="ad" frameborder=0 width=100% height=50 scrolling=no src=uploada.asp></iframe>
直接鏈接：uploada.asp
文件保存路徑：upload
上傳文件類型和大小自己設置
===========================================
第一個文件：inc/confing.asp（inc為文件夾名稱）
<%
Const EnableUploadFile="Yes" '是否開放文件上傳
Const MaxFileSize=200 '上傳文件大小限制
Const UpFileType="gif|jpg|bmp|png|swf|doc|txt|rar|zip" '允許的上傳文件類型
%>
