GMap.NET没有显示出地图 [英] GMap.NET shows no map
问题描述
我试图使用 GMap.NET.WindowsForms 在我的Windows控制窗体应用程序,但我不能让它告诉我任何地图
I'm trying to use the GMap.NET.WindowsForms control in my Windows forms application but I cannot make it show me any map.
下面是我做的:
我通过单击工具箱中的上下文菜单和浏览增加了控制我的Visual Studio 2010工具箱中选择项目...'为GMap.NET.WindowsForms.dll包含在下载的ZIP压缩文件。我还添加了我的解决方案,以GMap.NET.Core.dll和System.Data.SQLite.dll引用。
I added the control to my Visual Studio's 2010 toolbox by clicking 'Choose Items...' from the toolbox's context menu and browsing for the GMap.NET.WindowsForms.dll included in the downloaded zip archive. I also added references to GMap.NET.Core.dll and System.Data.SQLite.dll in my solution.
然后我把出现在工具箱上GMapControl我的应用程序的主要形式,并设置地图类型GoogleMap的。当我运行我的应用程序,但是,控制显示或者蓝屏一段文字说的很抱歉,但我们并不在这个缩放级别这个区域有图像或明亮的屏幕,完全没有数据( 。当我改变缩放级别)
Then I put the GMapControl that appeared in the toolbox on the main form of my application and set the map type to GoogleMap. When I run my application, however, the control shows either a blue screen with a piece of text saying "We are sorry, but we don't have imagery at this zoom level for this region" or a bright screen with completely no data (when I change zoom level).
下面是我的代码:
GMapMain.MapType = MapType.GoogleMap;
GMapMain.MaxZoom = 100;
GMapMain.MinZoom = 0;
GMapMain.Zoom = 50;
GMapMain.CurrentPosition = new PointLatLng(54.6961334816182, 25.2985095977783);
GMapMain.ReloadMap();
请帮忙。我不知道该怎么办,我无法找到在互联网上,可以帮助我解决这个问题的任何信息。
Please help. I have no idea what to do and I cannot find any information in the Internet that could help me solve the problem.
非常感谢你在前进。
推荐答案
尝试实例模式设置为服务器只
try setting the instance mode to server only
GMap.NET.GMaps。 Instance.Mode = GMap.NET.AccessMode.ServerOnly
GMap.NET.GMaps.Instance.Mode = GMap.NET.AccessMode.ServerOnly
