A question about office clipboard

hi,

i have hooked two api: OleGetClipboard and GetClipboardData. when we copy some data , the OleGetClipboard is automaticly called by office clipboard, when we press ctrl+v in a office document, the OleGetClipboard also be called. until now , when OleGetClipboard is called, i can know which process called the function,such as winword.exe, but i cant know exactly who is the caller , the document or the office clipboard.

in other word , i want to know the destination of the paste, is it the document or the office clipboard when a office process call the OleGetClipboard.

any ideas

thanks in advance.

Hi,

The Office clipboard is not a paste destination. It is simply a clipboard viewer. Any time an object is placed on the windows clipboard, the Office clipboard viewer receives a WM_CLIPBOARDUPDATE notification and responds by copying the data to its own private clipboard implementation. There isn't any really good way to know whether the clipboard is being accessed by the Office clipboard viewer or in response to a paste. Any possible solution would be little more than a guess and even if it worked, it would be at risk to be broken in a future version of Office since you would be relying on behavior we don't document.
