我可以获取Excel剪贴板数据的源范围吗？ [英] Can I Get the Source Range Of Excel Clipboard Data?

问题描述

如果剪贴板包含Excel工作表范围，则可以使用DataObject对象访问该范围的数据

If the Clipboard contains an Excel Worksheet Range, you can access that Range's Data with the DataObject Object

您还可以找到实际的源范围

或者该数据的 strong（即工作表，行和列）？或者，您是否可以找到最后复制范围？轮廓线是虚线（不是选定范围）？

Alternatively, can you find the Last Copied Range, which is indicated with a Dashed Outline Border (NOT the Selected Range)?

最好使用Excel 2003 VBA

Preferably using Excel 2003 VBA

推荐答案

在Excel 2019 64位中使用此代码来获取剪贴板上单元格的范围，而不是单元格的内容。

This code is being used in Excel 2019 64 bit to get the range of the cells on the clipboard as opposed to the contents of the cells.

fGetClipRange返回剪切或复制到剪贴板（包括书和图纸）的Excel范围的范围对象。它使用链接格式直接从剪贴板读取它，并需要此格式的ID号。与注册格式关联的ID可以更改，因此fGetFormatId从格式名称中查找当前格式ID。使用Application.CutCopyMode确定是否剪切或复制了单元格。

fGetClipRange returns a range object for the Excel range that is cut or copied onto the clipboard, including book and sheet. It reads it directly from the clipboard using the "Link" format, and requires the ID number for this format. The ID associated with the registered formats can change, so fGetFormatId finds the current format ID from a format name. Use Application.CutCopyMode to determine whether the cells were cut or copied.
