Using the TWebBrowser component (Delphi 5), I am looking for a way to store the 
HTML code of the TWebBrowser. When I use the right mouse button, I can store the 
HTML code, but I would like to do this programmatically.

Answer:

1   uses
2     ActiveX;
3   
4   {Saves the HTML document - referenced through 'Document' - to a stream}
5   
6   procedure SaveDocumentSourceToStream(Document: IDispatch; Stream: TStream);
7   var
8     PersistStreamInit: IPersistStreamInit;
9     StreamAdapter: IStream;
10  begin
11    {Delete content of stream}
12    Stream.Size := 0;
13    Stream.Position := 0;
14    {IPersistStreamInit - get document interface}
15    if Document.QueryInterface(IPersistStreamInit, PersistStreamInit) = S_OK then
16    begin
17      {Use StreamAdapter to get the IStream interface for our stream}
18      StreamAdapter := TStreamAdapter.Create(Stream, soReference);
19      {Save data from document into stream}
20      PersistStreamInit.Save(StreamAdapter, False);
21      {Destroy StreamAdapter. Optional.}
22      StreamAdapter := nil;
23    end;
24  end;
