Playing a Metafile into Another Metafile in Windows |
Q66950
The information in this article applies to:
- Microsoft Windows Software Development Kit (SDK) versions 3.0, 3.1
SUMMARY
Unlike 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 INFORMATION
Under 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.
