The ADOStreamConstruction interface is used to construct an ADO Stream object from an OLE DB IStream object in a C/C++ application.
Properties
| Property | Description |
|---|---|
| Stream | Read/Write. Gets/sets an OLE DB Stream object. |
Methods
None.
Events
None.
Remarks
Given an OLE DB IStream object (pStream), the construction of an ADO Stream object (adoStr) amounts to the following three basic operations:
Create an ADO Stream object:
Stream20Ptr adoStr; adoStr.CreateInstance(__uuidof(Stream));Query the IADOStreamConstruction interface on the Stream object:
adoStreamConstructionPtr adoStrConstruct=NULL; adoStr->QueryInterface(__uuidof(ADOStreamConstruction), (void**)&adoStrConstruct);
Call the IADOStreamConstruction::get_Stream property method to set the OLE DB IStream object on the ADO Stream object:
IUnknown *pUnk=NULL;
pRowset->QueryInterface(IID_IUnknown, (void**)&pUnk);
adoStrConstruct->put_Stream(pUnk);
The resultant adoStr object now represents the ADO Stream object constructed from the OLE DB IStream object.
Requirements
