我有一些宏需要它运行一些代码，然后提示用户从另一个程序中导出Excel工作簿，然后在导出打开后运行更多代码。棘手的部分是某些程序导出到Excel的新实例，而其他程序导出到当前实例。在新的Excel实例中捕获打开的工作簿
当前工作流程（在底部代码）：
呼叫中心“捕获”模块与所述出口的名称（一些 程序导出“书[X]”一些做“工作簿[ x]'等）以及您希望在找到导出后运行的 过程。
Capture Module从所有 Excel实例中获取所有现有工作簿名称的列表，并将其保存为模块级字符串。
Capture Module使用Application.OnTime，以便每隔3秒扫描所有Excel实例中所有工作簿的列表。
如果找到一个工作簿，是不是在 所有现有的工作簿名先前保存的列表，包含 出口的名称，它存储工作簿作为公共模块级变量， 并运行从步骤1中保存的程序，其可以参考 商店工作簿。
这工作得很好在所有情况下，除非为一个。如果我已在当前的Excel实例中打开Book1.xlsx，并且第三方程序将Book1.xlsx导出到Excel的新实例，程序不会将其识别为导出，因为Book1.xlsx位于现有工作簿名称字符串数组已经。
我的解决方案是找到某种方式来唯一标识比“名称”或“路径”更好的每个工作簿。我尝试将现有工作簿名称字符串中的每个工作簿名称保存为[application.hwnd]！[工作簿名称]，但这是一个不稳定的修复并且经常发生（我不太了解hwnd如何工作，所以我不能说为什么） 。
任何想法？谢谢！

很难处理这样的进程外的东西，有没有一种方法，而不是你可以提示用户导出/保存为输出Excel文件？然后您只需要一个FileDialog并提示用户从另一个应用程序中选择（导出）文件。 –
应该起作用的一个想法是，不是缓存打开的工作簿名称列表，而是为每个工作簿分配一个'CustomDocumentProperty'，您可以合理确保在导出的XLSX文件中不存在'CustomDocumentProperty'。然后，您可以简单地扫描文件（按名称）的应用程序/工作簿，该文件没有**属性。 –
@DavidZemens这是一个有趣的想法！如果我的hWnd下面的解决方案不起作用，我会在下一次尝试你的。非常感谢你的帮助！ –
