[re] 3. api - GetClipboardData function

Post URL : http://cugz.sjworks.net/bbs/zboard.php?id=qna&no=735

The GetClipboardData function retrieves data from the clipboard in a specified format. The clipboard must have been opened previously.
GetClipboardData 함수는 지정한 포맷의 데이터를 클립보드에서 꺼낸다.
이전에 클립보드가 반드시 열려야 한다.

HANDLE GetClipboardData(
    UINT uFormat         // clipboard format
   );
실수함수: GetClipboardData(실수: uFormat);
예상

Parameters
파라메터

uFormat

Specifies a clipboard format. For a description of the clipboard formats, see the SetClipboardData function.
클립보드 포맷을의미. 포맷에 관한 더 많은 정보는 SetClipboardData함수 참조.

Return Values
반환 값

If the function succeeds, the return value is the handle of a clipboard object in the specified format.
성공시에는 지정한 포맷의 핸들으로 리턴.
If the function fails, the return value is NULL. To get extended error information, call GetLastError.
함수 실패시, 널(빈) 값 리턴. 자세한 에러 정보는 GetLastError 함수이용.

Remarks
참조

An application can enumerate the available formats in advance by using the EnumClipboardFormats function.
The clipboard controls the handle that the GetClipboardData function returns, not the application. The application should copy the data immediately. The application cannot rely on being able to make long-term use of the handle. The application must not free the handle nor leave it locked.
The operating system performs implicit data format conversions between certain clipboard formats when an application calls the GetClipboardData function. For example, if the CF_OEMTEXT format is on the clipboard, a window can retrieve data in the CF_TEXT format. The format on the clipboard is converted to the requested format on demand. The following table shows the clipboard data type conversions that are available. Note that some of these automatic type conversions are not available on all platforms.

Clipboard Format        Conversion Format        Platform Support
CF_BITMAP        CF_DIB                Windows NT, Windows 95
CF_DIB                CF_BITMAP        Windows NT, Windows 95
CF_DIB                CF_PALETTE        Windows NT, Windows 95
CF_ENHMETAFILE        CF_METAFILEPICT        Windows NT, Windows 95
CF_METAFILEPICT        CF_ENHMETAFILE        Windows NT, Windows 95
CF_OEMTEXT        CF_TEXT                Windows NT, Windows 95
CF_OEMTEXT        CF_UNICODETEXT        Windows NT
CF_TEXT                CF_OEMTEXT        Windows NT, Windows 95
CF_TEXT                CF_UNICODETEXT        Windows NT
CF_UNICODETEXT        CF_OEMTEXT        Windows NT
CF_UNICODETEXT        CF_TEXT                Windows NT

If the operating system provides an automatic type conversion for a particular clipboard format, there is no advantage to placing the conversion format(s) on the clipboard.
If the system provides an automatic type conversion for a particular clipboard format, and you call EnumClipboardFormats to enumerate the clipboard data formats, the operating system first enumerates the format that is on the clipboard, followed by the formats to which it can be converted.

If the clipboard contains data in the CF_PALETTE format, the application should use the SelectPalette and RealizePalette functions to realize any other data in the clipboard against that logical palette.
See SetClipboardData for further information on specific clipboard data formats.
