IsClipboardFormatAvailable function (winuser.h)

Determines whether the clipboard contains data in the specified format.

BOOL IsClipboardFormatAvailable(
  [in] UINT format
);

[in] format

Type: UINT

A standard or registered clipboard format. For a description of the standard clipboard formats, see Standard Clipboard Formats .

Type: BOOL

If the clipboard format is available, the return value is nonzero.

If the clipboard format is not available, the return value is zero. To get extended error information, call GetLastError.

Typically, an application that recognizes only one clipboard format would call this function when processing the WM_INITMENU or WM_INITMENUPOPUP message. The application would then enable or disable the Paste menu item, depending on the return value. Applications that recognize more than one clipboard format should use the GetPriorityClipboardFormat function for this purpose.

For an example, see Pasting Information from the Clipboard.
