1. 下面的代码演示了如何在服务端获取来自客户端浏览器中某一个图片的x,y坐标，注意input控件的类型是image类型。

<form>
<Input Name="ImageMap" Type="Image" Src="ImageMap.jpg" Alt="Click Anywhere">
</form>

<%ImageMap.x = <%=Request("ImageMap.x")
ImageMap.y = <%=Request("ImageMap.y")%>
  2. 利用ADODB.Stream对象，在IE浏览器中下载服务端上的各类文件。

  即直接提示用户下载而不是由浏览器打开某些文件。注意，下面的代码拷贝到ASP文件中后，不要再添加一些非ASP代码在页面中：如HTML和Javascript客户端的代码。
