vb的Inet1控件的Openurl方法获取网页源码不全，是不是我写的代码有问题，少参数

   Recv = Inet1.OpenURL("http://www., 1)
                  Do Until Inet1.StillExecuting = False
                    DoEvents
                  Loop
                 
                  a = Utf8ToUnicode(Recv)
                  Richitextbox1.Text = a

获取百度就正常，因为百度源码少，获取大的网站源码只能获取一点
