lpString
Points to the buffer where the copy of the format name is to be stored.
Called when the Clipboard contains a data handle for the CF_OWNERDISPLAY format (that is, when the Clipboard owner will display the Clipboard contents) and the Clipboard owner should provide a name for its format.
Override this member function and copy the name of the CF_OWNERDISPLAY format into the specified buffer, not exceeding
the maximum number of bytes specified.
This message-handler member function calls the Default member function. Override this member function in your derived class to handle the WM_ASKCBFORMATNAME message.
