This is a bit of a long shot, but if anyone can figure it out, you guys can…
In Windows XP, is there any meta-data that comes with a cut and paste action, from which I can ascertain the application that provided the clipboard contents?
Bonus question… if there is such information, is there any way I can access it through a Java app?
That depends on the clipboard format. If it is plain-text, then no. Unless you want to install global hooks on the clipboard.
Which you cannot do from Java.
