问题
Is there a way to retrieve several items from the clipboard? I'm using something like this:
Dim clipboard As MSForms.DataObject
Dim str1 As String
Dim str2 As String
Set clipboard = New MSForms.DataObject
clipboard.GetFromClipboard
str1 = clipboard.GetText(1)
str2 = clipboard.GetText(2)
However, I get an error where I assign a value to my second variable that says the following:
Run-time error '-2147221404 (800040064)':
DataObject:GetText Invalid FORMATETC Structure
Help is much appreciated!

Turns out there are two clipboards: the Windows clipboard and the Office clipboard.
The Office clipboard can hold up to 24 items (all can be the same type), whereas the Windows clipboard can only hold one item of each type.
- Copying to the Windows clipboard is as easy as highlighting then typing Ctrl-C.
- Copying to the Office clipboard is as easy as highlighting then typing Ctrl-CC. The Office clipboard is only active if there is at least one Office application open and active at the time.
In VBA, using the MSForms.DataObject only gets you access to the Windows clipboard, so there is only a single text item available. After a variety of searches, I'm not able to find out how to open/control/copy/paste using the Office clipboard from VBA.
Having said all that, there is likely little reason to use any clipboard when writing and running a VBA macro. You can (temporarily) store those values in unused cells on a worksheet, in a public variable, in a public object, or even a private variable (probably with publically accessible properties). All of those methods serve exactly the same purpose as storing data in the clipboard.
In skimming around the interwebz on this topic, I ran across several references to using the clipboard to copy data between different workbooks, or between Office apps like Excel-to-Word. You still don't need the clipboard for this, as VBA can open the remote/external application/workbook/document and copy/paste the data directly.
