excel - 在 VBA 中检索复制的单元格范围的位置

Question

我希望能够复制一个单元格并仅粘贴数字格式。不幸的是，PasteSpecial 命令中没有内置选项。

有没有办法按下复制按钮，选择一些目标单元格，运行宏，并能够以类似于 VBA 中的选择对象的方式检索复制的单元格，以便我可以使用它的属性？

我能想到的唯一选择是粘贴到已知的空范围(非常远)，然后使用该中间范围，如下所示:

Dim A As Range
Set A = Range("ZZ99999")
A.PasteSpecial Paste:=xlPasteAll
Selection.NumberFormat = A.NumberFormat

谢谢!

查找 olelib.tlb在 Internet 上(Edanmo 的 OLE 接口(interface)和功能)。应该有很多下载链接。从您的 VBA 项目下载和引用(工具 - 引用)。

请注意，它不包含任何可执行代码，仅包含 OLE 函数和接口(interface)的声明。

此外，您可能会注意到它相当大，大约 550kb。您可以从中仅提取所需的接口(interface)并重新编译以获得更轻量级的 TLB 文件，但这取决于您。
(如果您真的对 TLB 不满意，还有一条黑魔法路线，您根本不需要任何 TLB，因为您可以动态创建程序集 stub 来直接调用 vTable 方法，但我不会感觉像移植这样下面的代码。)

然后创建一个辅助模块并将此代码放入其中:

Option Explicit
