Playing a Metafile into Another Metafile in WindowsLast reviewed: January 5, 1995Article ID: Q66950 |
The information in this article applies to:
SUMMARYUnlike Windows versions 2.x, versions 3.0 and 3.1 of Microsoft Windows permit an application to play a metafile into another metafile. Under Windows 3.0, the destination metafile must be a disk-based metafile. This restriction has been removed from Windows 3.1.
MORE INFORMATIONUnder Windows 3.0, playing a metafile into a new memory metafile fails. The following is a code fragment that demonstrates the correct procedure for successfully playing a metafile into a new, disk-based metafile that is compatible with both Windows 3.0 and 3.1.
// declare variables HANDLE hDestDC, hSrcHmf; // get a handle to the source metafile hSrcHmf = GetMetaFile((LPSTR)"SOURCE.WMF"); // create a disk-based destination metafile // NOTE: The parameter cannot be NULL. // That would create a memory metafile. hDestDC = CreateMetaFile((LPSTR)"DEST.WMF"); // play the source metafile into the newly created metafile PlayMetaFile(hDestDC, hSrcHmf) ; // get rid of the source metafile DeleteMetaFile(hSrcHmf) ; // close the destination metafile hSrcHmf = CloseMetaFile(hDestDC) ;At this point, the handle to the destination metafile can be used, or it can be deleted and retrieved later when it is needed.
