Question

我的Google-maps api会在大西洋上加载地图，而我的标记则指向其他地方。

我检查了我的代码，纬度和长坐标都是正确的，并在地图上标出。

有人可以帮我解决这个问题吗？

    Dim GeoLongitude As Double
    Dim GoogleGeoCoderKey As String = keyvar
    Dim GoogleResult1 As GoogleResult

        If GoogleResult1.Locations.Count = 1 Then
            For Each loc As Location In GoogleResult1.Locations()

可以在以下网站上查看实际结果：http://www.stripdagenhaarlem.nl/Programma-Stripdagen-Haarlem.html?cb=T如果缩小地图，您会看到标记放置正确。但是，地图会一直缩放到错误的位置。

尝试并加载变量以使代码看起来像

<html xmlns=http://www.w3.org/1999/xhtml><head><meta http-equiv=Content-Type content=text/html; charset=utf-8 /><body topmargin=0 leftmargin=0  ><iframe width=574 height=275 frameborder=0 scrolling=no marginheight=0 marginwidth=0 src=https://maps.google.com/maps?hl=en&amp;ie=UTF8&amp;ll=" & GLLat & "," & GLLong & "&amp;spn=0.819443,1.454315&amp;t=h&amp;z=18&amp;output=embed></iframe></body></html>

确保scrolling = no和z = 18，z是最初从

开始的缩放

您必须自己将变量拼凑在一起：P

希望这会有所帮助

Google地图从标记加载不同的位置
