IHtmlFramesCollection2为何得不到iframe得内容呢

[kunge82]

var
doc:IHTMLDocument2;
framewin2:IHtmlWindow2;
i,j:integer;
item1,m:OleVariant;
item:IDispatch;
tstr:string;
mf:IHtmlFramesCollection2;

begin
doc:=WebBrowser1.Document as IHTMLDocument2;
mf:=doc.get_frames;
Memo1.Lines.Add(IntToStr( mf.length));
for i:=0 to mf.length-1 do
begin
m:=i;
item:=mf.item(m);
item.QueryInterface(IID_IHTMLWindow2,framewin2);
if assigned(framewin2) then
Memo1.Lines.Add(IntToStr(framewin2.document.links.length)) ;

end;



end;
为什么提示拒绝呢

这同安全选项有关..你在IE的安全设置里面可以看到相关设置.
