clipboard data changed notification

[Rashid-Malik]

How can I find out when the clipboard data has changed without constantly polling the clipboard? Can windows notify me about the change? How?

Not sure if will work for LabVIEW, but essentially you need to register the window to receive messages from the clipboard. This is done using the SetClipboardViewer function. As for receiving/monitoring messages, the message you want is the WM_DRAWCLIPBOARD message. This is sent to the window that was registeres with the SetClipboardViewer function. There's an example here on monitoring Windows messages.
