BOOL IsClipboardFormatAvailable(wFormat)
This function specifies whether data of a certain type exist in the clipboard.
| Parameter | Type/Description |
| wFormat | WORD Specifies a registered clipboard format. For information on clipboard formats, see the description of the SetClipboardData function, later in this chapter. |
The return value specifies the outcome of the function. It is TRUE if data having the specified format are present. Otherwise, it is FALSE.
This function is typically called during processing of the WM_INITMENU or
WM_INITMENUPOPUP message to determine whether the clipboard contains data
that the application can paste. If such data are present, the application typically enables
the Paste command (in its Edit menu).
