Display a map in a Windows Form app
提问by Sailing Judo
I built a Winform app several months ago that schedules appointments for repair techs. I'd like to update the app by adding a map for the customer's address on the customer form, and then print that map on the report the techs take when they leave the office.
几个月前，我构建了一个 Winform 应用程序，用于安排维修技术人员的约会。我想通过在客户表单上添加客户地址的地图来更新应用程序，然后将该地图打印在技术人员离开办公室时所采取的报告上。
I've been looking around but I haven't found a good solution for this yet.
我一直在环顾四周，但我还没有找到一个好的解决方案。
I currently have an address for the customer. What I'd like to do is submit the address to one of the popular online map sites and get a minimap of the locale. I can almostdo this with Google maps using their embedded link feature. I can get the following HTML after adding an address to their website:
我目前有客户的地址。我想要做的是将地址提交到一个流行的在线地图网站，并获取该地区的小地图。我几乎可以使用谷歌地图的嵌入式链接功能来做到这一点。将地址添加到他们的网站后，我可以获得以下 HTML：
<iframe width="300" height="300" frameborder="0" scrolling="no"
marginheight="0" marginwidth="0"
src="http://maps.google.com/maps?hl=en&ie=UTF8&t=h&g=1193+Presque+Isle+Dr,+Port+Charlotte,+FL+33952&s=AARTsJqsWtjYwJ7ucpVS6UU2EInkRk6JLA&ll=27.012108,-82.087955&spn=0.005735,0.006437&z=16&output=embed">
</iframe>
My first plan was to simply parse this HTML and insert whichever customer's address was needed in place this address, then show the result in a browser object on the form. However, if I change the address in the above iframe Google gives me a "Your client does not have permission to get URL ..." message.
我的第一个计划是简单地解析这个 HTML 并插入任何需要的客户地址来代替这个地址，然后在表单上的浏览器对象中显示结果。但是，如果我更改上述 iframe 中的地址，Google 会给我一条“您的客户无权获取 URL ...”消息。
I have no preference on which map service I ultimately use, the important thing is that the solution can't have an associated expenses and its usable from Windows forms.
我对最终使用的地图服务没有偏好，重要的是该解决方案不能有相关费用，并且可以从 Windows 表单中使用。
Anyone got an ideas/recommendations/resources on how to tackle this?
任何人都有关于如何解决这个问题的想法/建议/资源？

结果：
I ended up using the control found here. I find it an "okay" solution... it's tedious to get working as the code does not work as-is. I'm pretty stunned to find that none of the popular map APIs support winforms.
我最终使用了此处找到的控件。我发现这是一个“不错”的解决方案......因为代码不能按原样工作，所以开始工作很乏味。我很惊讶地发现没有一个流行的地图 API 支持 winform。

Both Google Maps and Live Maps have a public api.
Google Maps 和 Live Maps 都有一个公共 API。
Since you are doing winforms I'd probably use live maps.
既然你在做 winforms，我可能会使用实时地图。

There is some example codefor developing a map viewer control (NB: I doubt this is strictly within their licence)
有一些用于开发地图查看器控件的示例代码（注意：我怀疑这是否严格在他们的许可范围内）
Otherwise, depending on your budget, you could use the MapPoint ActiveX control
否则，根据您的预算，您可以使用MapPoint ActiveX 控件

Just use the value inside the src="" as the location for a WebBrowser control directly, without the IFRAME.
只需直接使用 src="" 中的值作为 WebBrowser 控件的位置，无需 IFRAME。
OR
或者
Build a minimal html document wrapping the IFRAME, write it out to a MemoryStream, re-seek it back to the start, and use the MemoryStream to set the WebBrowser control's DocumentStream property.
构建一个包装 IFRAME 的最小 html 文档，将其写出到 MemoryStream，重新寻找它回到起点，并使用 MemoryStream 设置 WebBrowser 控件的 DocumentStream 属性。
