您可能希望删除工作表，而不是在其中放入错误消息，或者发送MsgBox…

我运行过一次，但失败了。在查询行上放置断点，将yahoo地址加载到我的浏览器中以确保其有效，然后脚本工作。我还确保项目中没有其他工作表。H下面是VBA编辑器的屏幕截图以及断点的位置：

您可以将变量粘贴到手表窗口中，然后胡闹看看它的功能。如果您为此提供了任何应用程序，我很想了解它们！

我无法让您的方法正常工作（在几个100秒的滴答声后，我会出现内存不足的错误）

因此，我感兴趣并进一步挖掘。下面我提出了另一种更复杂但效果更好的方法（我在3分钟内上传了500支标准普尔股票（Excel中的实际工作大约3秒钟，其余是连接/下载时间）。只需将整个代码复制粘贴到模块中，然后运行
