The GetClipboardOwner documentation does note:

"The clipboard can still contain data even if the clipboard is not
currently owned."

And the EmptyClipboard function documentation says:

"Before calling EmptyClipboard, an application must open the clipboard
by using the OpenClipboard function. If the application specifies a
NULL window handle when opening the clipboard, EmptyClipboard succeeds
but sets the clipboard owner to NULL."

I called GetLastError() , but it returns 0 as a result just with
acrobat reader , not for Notepad.exe ...etc

So what's the problem with adobe acrobat reader ? do they use an other
TECH with their Clipboard or what ?

Presumably they call OpenClipboard with a NULL window handle - as the
EmptyClipboard documentation says.
