OleCreateLinkToFile
Creates an object that is linked to a file.
STDAPI OleCreateLinkToFile(
LPWSTR lpszFileName,
| //Points to source of linked object
| REFIID riid,
| //Interface to be used to communicate with the new object
| DWORD renderopt,
| //Value from OLERENDER
| LPFORMATETC pFormatEtc,
| //FORMATETC value depending on renderopt value
| IOleClientSite * pClientSite,
| //Pointer to an instance of IOleClientSite
| IStorage * pStg,
| //Pointer to an IStorage instance used as the object storage
| void ** ppvObj
| //Receives a pointer to the interface requested in riid
| );

Parameters
lpszFileName
Points to the source file to be linked to.
riid
Identifies the interface the caller later uses to communicate with the new
object (usually IID_IOleObject).
renderopt
Specifies a value from the enumeration OLERENDER that indicates the locally cached drawing or data-retrieval capabilities the
newly created object is to have. Additional considerations are described in the
Comments section below.
pFormatEtc
Specifies a value from the enumeration OLERENDER the indicates the locally cached drawing or data retrieval capabilities the
newly created object is to have. The OLERENDER value chosen affects the possible values for the pFormatEtc parameter.
pClientSite
Points to an instance of IOleClientSite, the primary interface through which the object will request services from
its container. May be NULL.
pStg
Points to an instance of the IStorage interface to be used as the storage for the object. This parameter may not be
NULL.
ppvObj
Receives a pointer to the interface requested in riid on the newly created object on return.
Return Values
S_OK
Indicates the object was created successfully.
STG_E_FILENOTFOUND
Indicates file name is invalid.
OLE_E_CANT_BINDTOSOURCE
Indicates not able to bind to source.
Comments
The OleCreateLinkToFile function differs from the OleCreateLink function because it can create links to non-OLE aware files (as well as files
that are OLE-aware) using the Windows Packager.
