SetClipboardData

The SetClipboardData function places data on the clipboard in a specified clipboard format. The window must be the current clipboard owner, and the application must have called the OpenClipboard function. (When responding to the WM_RENDERFORMAT and WM_RENDERALLFORMATS messages, the clipboard owner must not call OpenClipboard before calling SetClipboardData.)

HANDLE SetClipboardData(
  UINT uFormat, // clipboard format
  HANDLE hMem   // data handle
);
 

Parameters

uFormat

Specifies a clipboard format. This parameter can be a registered format or any of the standard clipboard formats. For more information, see Registered Clipboard Formats and Standard Clipboard Formats.

hMem

Handle to the data in the specified format. This parameter can be NULL, indicating that the window provides data in the specified clipboard format (renders the format) upon request. If a window delays rendering, it must process the WM_RENDERFORMAT and WM_RENDERALLFORMATS messages.

After SetClipboardData is called, the system owns the object identified by the hMem parameter. The application can read the data, but must not free the handle or leave it locked. If the hMem parameter identifies a memory object, the object must have been allocated using the GlobalAlloc function with the GMEM_MOVEABLE and GMEM_DDESHARE flags.

Return Values

If the function succeeds, the return value is the handle of the data.

If the function fails, the return value is NULL. To get extended error information, call GetLastError.

Remarks

The uFormat parameter can identify a registered clipboard format, or it can be one of the standard clipboard formats. For more information, see Registered Clipboard Formats and Standard Clipboard Formats.

The 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. For more information, see Synthesized Clipboard Formats.

Windows CE: The data to be set into the clipboard should be allocated using the LocalAlloc function.

Windows CE does not support the following uFormat values:

CF_GDIOBJFIRST through CF_GDIOBJLAST

CF_DSPBITMAP

CF_DSPENHMETAFILE

CF_DSPMETAFILEPICT

CF_DSPTEXT

CF_HDROP

CF_LOCALE

CF_OWNERDISPLAY

CF_PRIVATEFIRST through CF_PRIVATELAST

Windows CE does not perform any implicit conversions between formats.
