问题 Yep, I am not the first who is asking, but I didn't found an answer (maybe, because my english is bad). How to draw a polyline on a map? Not a route (direction), but just a polyline, like in JS Google Maps API with function Polyline. I can not understand. Thanks anyway. 回答1: Have a good read of this tutorial: http://www.independent-software.com/gmap-net-tutorial-maps-markers-and-polygons/ This should get you started: GMapOverlay polyOverlay = new GMapOverlay("polygons"); IList<PointLatLng>

问题 I'm using GMap.NET map control to display maps on my Windows Forms application. I recently upgraded to GMap.NET build "09991dd06609". After upgrading to the latest build, I'm getting the plus sign (+) on the centre of the map. I would like to remove that sign. I have gone through all the GMap.NET control properties but I could not find any property to remove it. When I was using the older build I was not getting the plus sign. 回答1: After some research I found the answer. I have used the

问题 I'm developing an application using Gmap in c# (great API, btw), not to confuse with google-map API, and I did some really cool and useful stuff ever since. My problem is that some of my clients won't have an internet connection, and that is why I need to be able to display the background (the map) offline. I used to use the property GMap.NET.AccessMode.ServerAndCache; to get my data from the server, and now I would like to be able to use GMap.NET.AccessMode.CacheOnly with a full cache.

问题 I have read almost all the tutorials and checked stack questions however I still do not know and do not understand how to manage WPF UserControls in MVVM, specially those provided by others like GMap.NET. I am trying to follow MVVM pattern in my app, however I have no idea how to initialize and manage GMap.NET WPF control in it. In standard approach it requires management like this: gmap.MapProvider = GMap.NET.MapProviders.GoogleMapProvider.Instance; GMap.NET.GMaps.Instance.Mode = GMap.NET

问题 I have this code that shows specific location I needed on my project. public partial class ViewLocation : Window { public ViewLocation() { InitializeComponent(); } private void gmap_Loaded(object sender, RoutedEventArgs e) { gmap.MapProvider = GMap.NET.MapProviders.GoogleMapProvider.Instance; gmap.Position = new GMap.NET.PointLatLng(13.4107591, 121.1764547); //gmap.SetPositionByKeywords("Calapan, Philippines"); gmap.MinZoom = 13; gmap.MaxZoom = 18; gmap.Zoom = 9; } } But I have to limit the

问题 I have yet another problem.. Consider looking at THIS first.. on my early problems, I needed to drag a button, and a form in relation to how I drag/move the pictureBox.. All controls are inside .NET Now I am working on this great Control, GMaps in which adapts the google's API in .NET framework. My goal is to create something like the infoWindow on google's API. so I resorted on customizing it by creating a new form (acting as the infoWindow) on the first link above. If you've seen Gmaps.net,

问题 I'm working on Win Forms application along with GMap.net(a library that enables us to use Google Maps in Win Forms Application). Coming straight to the point, I be able to get the coordinates i.e (Latitude and Longitude) where my mouse click (left click). private void gm1_MouseDoubleClick(object sender, MouseEventArgs e) { if (e.Button == System.Windows.Forms.MouseButtons.Left) { double lat = gm1.FromLocalToLatLng(e.X, e.Y).Lat; double lng = gm1.FromLocalToLatLng(e.X, e.Y).Lng; } } I did not
