Destructor. Frees all resources owned by the object, prior to its destruction. In particular, the file associated with the clipboard's store is closed.

Note that if the clipboard file store has no root stream, i.e. the CommitL() member function of CClipboard has not been called prior to deleting the CClipboard object, then the file associated with the clipboard file store is deleted.

Empties the clipboard.

Note that if the file associated with the clipboard's store does not exist, this is not regarded as an error and the function completes successfully.

Returns the clipboad file drive information stored in the TLS

Commits changes to the clipboard's store.

It externalises the stream dictionary to the clipboard store as the root stream and then commits all changes to the store. This function must be called after application data has been externalised; failure to do so results in the deletion of the file associated with the clipboard store and the loss of data.

Copies a double-precision floating point value to the clipboard.

Note that the function does not automatically commit changes to the clipboard's store. This must be done explicitly.

CommitL()

Constructs a clipboard object and prepares the clipboard's store for reading.

Constructs a clipboard object and prepares the clipboard's store for reading, placing a pointer to the object on the cleanup stack. This allows the object and allocated resources to be cleaned up if a subsequent leave occurs.

Constructs a clipboard object and prepares the clipboard's store for writing.

If the file associated with the clipboard's store does not exist, it is created; if it already exists, any existing content is discarded.

Pastes a double-precision floating point value from the clipboard.

If a double-precision floating point value exists on the clipboard, then the function restores it to the referenced argument and returns a true value.

If there is no double-precision floating point value on the clipboard, then the function returns a false value. The referenced argument is not changed.

Returns a reference to the clipboard's file store.

Returns a reference to the clipboard's stream dictionary.
