);

Parameters

pPS [in]

Remarks

The OleSave helper function handles the common situation in which an object is open in transacted mode and is then to be saved into the specified storage object which uses the OLE-provided compound file implementation. Transacted mode means that changes to the object are buffered until either of the IStorage::Commit or IStorage::Revert is called. Callers can handle other situations by calling the IPersistStorage and IStorage interfaces directly.

OleSave does the following:

Note  Static objects are saved into a stream called CONTENTS. Static metafile objects get saved in "placeable metafile format" and static DIB data gets saved in "DIB file format." These formats are defined to be the OLE standards for metafile and DIB. All data transferred using an IStream interface or a file (that is, via IDataObject::GetDataHere) must be in these formats. Also, all objects whose default file format is a metafile or DIB must write their data into a CONTENTS stream using these standard formats.
