在VBA中检索复制的单元格范围的位置 [英] Retrieve location of copied cell range in VBA

问题描述

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.

I'd like to be able to copy a cell and paste ONLY number formats. Unfortunately, there is no built-in option in the PasteSpecial command.

是否可以按复制按钮，选择一些目标单元格，运行宏并能够以类似于VBA中的Selection对象的方式检索复制的单元格，以便我可以使用其属性?

Is there a way to press the copy button, select some destination cells, run a macro, and be able to retrieve the copied cells in a way analogous to the Selection object in VBA so that I can use its properties?

我唯一想到的替代方法是粘贴到一个已知的空白范围(很远)，然后使用该中间范围，如下所示:

The only alternative I can think of is pasting to a known empty range (very far away) and then using that intermediate range, as below:

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

谢谢！

推荐答案

在Internet上查找 olelib.tlb (Edanmo的OLE接口和功能).应该有很多下载链接.从您的VBA项目下载并参考(工具-参考).

Find olelib.tlb on the Internet (Edanmo's OLE interfaces & functions). There should be plenty of download links. Download and reference from your VBA project (Tools - References).

请注意，它不包含任何可执行代码，仅包含OLE函数和接口的声明.

Note that it does not contain any executable code, only declarations of OLE functions and interfaces.

另外，您可能会注意到它很大，大约550kb.您只能从中提取所需的接口，然后重新编译以获得更轻巧的TLB文件，但这取决于您.
(如果您真的对TLB感到不满意，那么还有一条根本不需要任何TLB的黑暗魔术路线，因为您可以在运行时创建程序集存根以直接调用vTable方法，但是我不会想要移植下面的代码就是这种方式.)

Also you might notice it's quite big, about 550kb. You can extract only the needed interfaces from it and recompile to get a much lighter TLB file, but that is up to you.
(If you are really unhappy with a TLB, there is also the dark magic route where you don't need any TLBs at all because you create assembly stubs on the fly to call vTable methods directly, but I won't be feeling like porting the below code this way.)

然后创建一个帮助器模块，并将以下代码放入其中:

Then create a helper module and put this code into it:
