The Windows Clipboard application, CLIPBRD.EXE, lets the user view the contents of the clipboard; for this reason, it is also known as the “clipboard viewer.” It lists the names of all the formats for which handles (NULL or otherwise) exist in the clipboard, and displays the contents of the clipboard in one of these formats.
The clipboard viewer can display all the standard data formats. If there are handles for more than one standard data format, the clipboard viewer displays only one format, choosing from the following list, in decreasing order of priority: CF_TEXT, CF_OEMTEXT, CF_METAFILEPICT, CF_BITMAP, CF_SYLK, and CF_DIF.
