=========================
下面是左轻候的一段代码
//实现内容
procedure Tform1.ShowHTML(src:string;iebrw:TEmbeddedWB;ID:integer);
var
vv: Variant;
HTMLDocument: IHTMLDocument2;
tmpStr,tmpfilepath:string;0D
begin
//直接写到浏览器里。
vv := VarArrayCreate([0,0],varVariant);
vv[0] := ' <base href= "'+LocalPath+' "/ >'+ src+ tmpStr;
try
ieBrw.Navigate('about:blank'); //这里必须要
HTMLDocument := iebrw.Document as IHTMLDocument2;
HTMLDocument.write(PSafeArray(TVarData(vv).VArray));
HTMLDocument.charset:3D 'gb2312';
HTMLDocument.close;
except
statusbar1.Panels[0].Text:='写浏览器出错';
end;
HtmlDocument:=nil;
end;
两者还有是有区别的。写完后，第一个方法不会改变当前页默认的路径，就是说她是直接改内容。
而第二个就不行了，她完成后，你就会发现网页的属性为 "about:blank "
我也说不太清楚。请自己认真体会啊
