A memory object that is to be placed on the clipboard should be allocated by using the GlobalAlloc function with the GMEM_MOVEABLE flag.
After a memory object is placed on the clipboard, ownership of that memory handle is transferred to the system. When the clipboard is emptied and the memory object has one of the following clipboard formats, the system frees the memory object by calling the indicated Win32 function:
| Function to free object | Clipboard format |
|---|---|
| DeleteMetaFile | CF_DSPENHMETAFILE CF_DSPMETAFILEPICT CF_ENHMETAFILE CF_METAFILEPICT |
| DeleteObject | CF_BITMAP CF_DSPBITMAP CF_PALETTE |
| GlobalFree | CF_DIB CF_DIBV5 CF_DSPTEXT CF_OEMTEXT CF_TEXT CF_UNICODETEXT |
| None | CF_OWNERDISPLAY |
When the clipboard is emptied of a CF_OWNERDISPLAY object, the application itself must free the memory object.
