vba - 在 Excel 2016 中运行 VBA 时出现 OLE 错误？

Question

我正在尝试使用 Excel 作为数据库，并且正在遵循 this site 中的教程。 .

问题是，每当我尝试在下面的文件中“更新下拉菜单”时，我都会收到此错误:“Microsoft 正在等待另一个应用程序完成 OEL 操作”。

我在这里错过了什么或做错了什么，我该如何做正确的事情？

我使用的是最新的 Excel 2016 Home & Student。我还在打开工作簿时启用了宏。

同一个文件在 Excel 2007 中打开时运行完美。我还注意到 Microsoft ActiveX Data Objects 6.0 库在示例中引用了“msado60.dll”，而在 Excel 2016 中它是“msado60.tlb”文件(我用的)。

根据注释，您的 OpenDB 方法正在打开 ADO 连接。您似乎没有在任何地方关闭它。

您正在尝试重新打开已打开的连接。 OLE 服务器错误告诉您服务器 (Excel) 正忙，因为已经有另一个 ADO 连接连接到它。您需要做的就是确保仅打开连接一次，然后在使用完毕后将其关闭。
