      • CF_LOCALE

        static final int CF_LOCALE
        The data is a handle to the locale identifier associated with text in the clipboard. When you close the clipboard, if it contains CF_TEXT data but no CF_LOCALE data, the system automatically sets the CF_LOCALE format to the current input language. You can use the CF_LOCALE format to associate a different locale with the clipboard text.

        An application that pastes text from the clipboard can retrieve this format to determine which character set was used to generate the text.

        Note that the clipboard does not support plain text in multiple character sets. To achieve this, use a formatted text data type such as RTF instead.

        The system uses the code page associated with CF_LOCALE to implicitly convert from CF_TEXT to CF_UNICODETEXT. Therefore, the correct code page table is used for the conversion.

        Constant Field Values

      • CF_PALETTE

        static final int CF_PALETTE
        Handle to a color palette. Whenever an application places data in the clipboard that depends on or assumes a color palette, it should place the palette on the clipboard as well.

        If the clipboard contains data in the CF_PALETTE (logical color palette) format, the application should use the SelectPalette and RealizePalette functions to realize (compare) any other data in the clipboard against that logical palette.

        When displaying clipboard data, the clipboard always uses as its current palette any object on the clipboard that is in the CF_PALETTE format.
