I used to be able to use Windows API calls in Excel VBA to set text on the clipboard. But ever since upgrading to 64-bit Office 2013, I cannot. Below is some code that does not error, but it is also not setting any text on the clipboard. Can someone help me test and troubleshoot?
After pasting the code below into a code module in VBA, you can test it in the immediate windows by typing Clipboard_SetData("Copy this to the clipboard.")
and it should set that text on the clipboard and you would be able to paste it into any other application.
(I am using Windows 8, so I cannot use Microsoft Forms or the Data Object to manipulate the clipboard. It does not work properly on Windows 8.)
UPDATE and EDIT: Code below has been corrected and now works properly in 64-bit Excel, thanks to Jason Kurtz' answer below. If you find this useful, please vote his answer up.

OK, I got it now...
You need to change this line in your version of the code:
Private Declare PtrSafe Function lstrcpy Lib "kernel32" (ByVal lpString1 As String, ByVal lpString2 As String) As LongPtr
To this:
Private Declare PtrSafe Function lstrcpy Lib "kernel32" (ByVal lpString1 As Any, ByVal lpString2 As Any) As LongPtr
If you step through the code as you had it, you will see that the value of lpGlobalMemory changes when lstrcopy is called. When the types are changed to Any, the value stays the same.
Works for me on windows 7. Hope it works for you!

Use the code exactly as shown here:

except insert PtrSafe after Declare for all the API declarations.
The code should be in a module by itself.
