如何使用纬度和经度使用GoogleMap在webBrowser控件中导航地图

Question

在WebBrowser控件中插入坐标[long / lat]来导航google map的正确方法。问题是它什么也没显示...

我的代码：

Dim address as New StringBuilder
Dim long as String    'the longitude
Dim lat as String     'latitude

address.Append("http://maps.google.com/maps?q=" & lat & "," & "+" & long)

webBrowser1.Navigate(address.toString)
