ASP.NET中如何使用SWFUpload上传文件
ASP.NET中如何使用SWFUpload上传文件来源：网络转摘 作者：佚名 浏览： 1784 次 2009-2-20 17:44:53
前陣子有人提到這個上傳工具,小弟沒玩過就給它抓下來試試
SWFUpload可以支援多檔上傳功能,還不錯用,小弟分享一下試用的結果
首先要將官網的Demo Sample抓下來,如下所示：
SWFUpload下載網址：http://swfupload.googlecode.com
SWFUpload 下載檔案：SWFUpload-Samples v2.1.0.Release.zip
在\SWFUpload Samples v2.1.0\demos\applicationdemo.net目錄裡有下列檔案
接下來只要修改Default這支程式就可以了..我 只增加了儲存選取檔案的功能..
和清除目前選取檔案的功能..更多的功能就要自己去修 改了...
