微软公司推出的IE4.X，使得按照HTML4标准制作的网页一时成为时尚，这类网页在动态功能方面有了非常大的提高。特别是可以通过页面内嵌的Script语句，使页面中的任意一段文字可以在需要时显示出来，在不需要时隐藏起来，利用这可以用waitfor组件. 下面是国外的一名ASP作者的语句:
Developer"s often need to have their apps wait a specified number of
seconds, detect if a file exists within a particular timeout or wait
for exclusive file access within a specified timeout. This component
is designed to allow developers to do that from ASP.
To install
a) Move the component into the subdirectory you want to store it in
b) Type regsvr32 waitfor.dll
c) Run markwait.exe to mark the registry
d) Move the example script into a directory off your Web server
e) Modify the example for your own use
Unfortunately I cannot provide free support for this free component.
Best wishes,
Stephen
