WM_ASKCBFORMATNAME

The WM_ASKCBFORMATNAME message is sent to the clipboard owner by a clipboard viewer window to request the name of a CF_OWNERDISPLAY clipboard format.

WM_ASKCBFORMATNAME 
cchName = (DWORD) wParam            // size of buffer 
lpszFormatName = (LPTSTR) lParam    // buffer to receive format name 
 

Parameters

cchName

Value of wParam. Specifies the size, in characters, of the buffer pointed to by the lpszFormatName parameter.

lpszFormatName

Value of lParam. Pointer to the buffer that is to receive the clipboard format name.

Return Values

If an application processes this message, it should return zero.

Remarks

In response to this message, the clipboard owner should copy the name of the owner-display format to the specified buffer, not exceeding the buffer size specified by the cchName parameter.

A clipboard viewer window sends this message to the clipboard owner to determine the name of the CF_OWNERDISPLAY format — for example, to initialize a menu listing available formats.
