I have a handle returned from the clipboard which points to a metafile. I want to convert it to the metafile structure so that I can save it to the disk.

How can I do it.

Thanks in advance

I assume the handle from the cipboard is a handle to a global memoy block in which case you should be able to do somthing like
GlobalLock this returns a ptr to the data so you can cast this to a ptr to the metafile struct.

If it is an handle to metafile, i.e. HMETAFILE (if it is HENHMETAFILE for enhanced meta files) try using CopyMetaFile or CopyEnhMetaFile functions.

It is something like

CopyEnhMetaFIle(hMetaFileHandle, *pFile);
