获取 IE 当前 URL 的代码,网上有许多类似代码，但在WINDOWSXP 下不能运行。查了一些资料，发现由于Win2000，WINXP 是基于Unicode代码的操作系统，所以没有WorkerA类，而以WorkerW类取而代之（XXXXA should be used on not unicode compliant windows oses likes Windows 95,98 etc and on unicode enabled oses replace A with W. Remember WorkerA or WorkerW doesn't have something related to IE version. To obtain all of the opened IEs URL use EnumWindows callback function and cheers. ）。
