Question

我的一位朋友已将Google地球插件嵌入到C＃用户控件中。一切正常，但是当你关闭窗口时，我们收到“未指定的错误”，并选择继续运行脚本。从我们的跟踪它看来这是由谷歌正在下降到页面上的脚本引起的。有什么想法吗？

Answer 1

以下是c＃/ Google Earth API集成的一个示例，它涵盖了您遇到的问题（请参阅评论） http://fraserchapman.blogspot.com/2008/08/google-earth-plug-in-and-c.html

此外，这是我的另一个项目，它使用COM Google地球插件类型库（plugin_ax.dll）转换为公共语言运行时程序集中的等效定义。它可能有一些用处。 http://fraserchapman.blogspot.com/2008/12/google-earth-plugin-control-library.html

Answer 2

我们现在已经在IE和FF中尝试了这个。工作良好。任何想法为什么只出现错误？我们可以以某种方式禁用它吗？这是我们的代码。
