OleSaveToStream
Saves an IPersistStream object to the specified stream.
HRESULT OleSaveToStream(
IPersistStream * pPStm,
| //Points to the object to be saved
| IStream * pStm
| //Points to the destination stream to which the object is saved
| );
|
|
Parameters
pPStm
Points to the IPersistStorage object to be saved to the stream. Can be NULL, which has the effect of
writing CLSID_NULL to the stream.
pStm
Points to the stream in which the object is to be saved.
Return Values
S_OK
Indicates the object was successfully saved.
STG_E_MEDIUMFULL
Indicates there is no space left on device to save the object.
See also the WriteClassStm function for other error return values.
See also the IPersistStream::Save method for other error return values.
Comments
This function simplifies saving an IPersistStream object to a stream. The object is saved preceded by its CLSID. The OleSaveToStream function performs the following steps:
- Calls the IPersistStream::GetClassID method to get the object's CLSID.
- Writes the CLSID to the stream with the WriteClassStm function.
- Calls the IPersistStream::Save method with fClearDirty set to TRUE. Note that this clears the dirty bit in the object.

.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
