ActiveServerPage技术为应用开发商提供了基于脚本的直观、快速、高效的应用开发手段，极大地提高了开发的效果。在讨论ASP的安全性问题之前，让我们来看看ASP是怎么工作的。关于图片上传的例子在网上有良多文章和原代码。可是每次上论坛扫瞄帖子的时分都是看到良多网友对图片上传感应头疼和贫苦。实在这个成绩也是已经让我感应头疼。也看过了很多的文章和代码。如今我写的这篇文章是把我对照喜好的一篇代码和动网里的妙手对这篇代码优化后再加上我增添一些代码分离出来的！呵呵，实在这篇文章是沾了写这篇代码的人(稻喷鼻居士)和动网里那些妙手的光。:)
好了，不说空话了。入手下手来搭建所必要的情况和数据布局！
先新建一个名字叫photo的文件夹。(我在这里就是把图片上传到这个文件夹里的。)创建一个名字叫database的数据库。再接着创建一个名字叫sFile的表。内外计划四个字段分离是id(int),image(varchar),image1(varchar),image2(varchar)。我这里用的数据库是SQL。

呵呵，代码多了点。复制以上的代码到你的呆板上运转是否是你想要的了局！至于显现图片信任人人都分明了吧！我就不用多说了。值得一提的是此代码不但能够用于图片上传而是任何格局的文件都能够哦，至于文件巨细也能够由你本人来界说哦！另有的就是我只界说了上传三个如果要上传更多的话稍为改下代码就能够了。细心看代码就晓得了是否是以为很便利和有用。这个只不外是在我办理这个成绩的时分用的一种办法罢了。你如果有更好的办法来完成也能够来EMAIL告知我！相互进修配合前进。第一次写文章大概表达方面有语法成绩。如果有甚么成绩也能够来EMAIL告知我！我的邮箱：hushuowang@163.net,QQ:11313112。工夫不早了，我要睡觉了！呼噜呼噜zzzZZZ....

问题是他们究竟是喜欢他们是使用软件时,速度快还是速度慢好.(当然在3秒以内).无论是他们输入资料时,查找资料时,分析资料时. |
