下面是发展而来的完整代码.
function GetHTMLCode2(WB: TWebBrowser): string;
var
ps: IPersistStreamInit;
s: string;
ss: TStringStream;
sa: IStream;
r:boolean;
begin
ps := WB.document as IPersistStreamInit;
s := '';
ss := TStringStream.Create(s);
try
sa:= TStreamAdapter.Create(ss, soReference) as IStream;
r := Succeeded(ps.Save(sa, Bool(True)));
if r then result:=ss.Datastring;
finally
ss.Free;
end;
end;
