<META NAME="Description" CONTENT="呵呵，哥们把vb的一个例子彻底转换成vbs脚本并移植到网页了，就为了做一个既好看性能又好的图表控件，哥们找了N多资料，光看VML就看的眼画了，本来想用VML写一个chart控件的，后来太麻烦了，直接用OWC算了，功能也暴强，OWC不用我介绍了吧，估计就算我费半天劲学好VML，再学好JS的面向对象开发，最后写出一个VMLCHART估计也没这么强大，微软免费提供的东西为什么不利用一下呢，昨天和今天刚看了MS的一个sql reporting serivice的视频教程，那个更NB，有空装一个，什么报表，图表统统搞定，不过什么东西都有缺点，我写的这个例子必须在客户端安装OFFICE才行，或者得单独分发OWC组件才行，我在对象声明的时候没有写DLL的位置，也没有引用网上的CAB包，大家测试的时候装个OFS200就可以了">
