I have an app where I allow the user to copy some data onto the clipboard, so that it can be dropped onto a text form or maybe a login form etc.
Is there a way that I can clear the clipboard after the data is pasted? So I effectively want to allow a 'paste once'. To do this I would need to detect if a paste event has occurred somewhere on the users desktop/computer. (Detecting a mouse up/down is not specific enough). Maybe I need to detect a CTRL-V too.
Is this possible?
I haven't tried it but does this work or something similar? Just add it after the 1st paste or something.
vb Code:
That is how I would clear the clipboard. It is detecting a 'paste event' that I am uncertain about.
Can I detect the keyboard and mouse activity when the app is not focussed?
Yea. With a keyboard and mouse hook.

It's C# but should be easy to convert.
ok, perfect, I'll give it a go.
