May 8, 2009 at 5:04 PM

It is very important for mi because I wrote main project for study.

Maby I Can help You and together complete faster ?

May 8, 2009 at 5:07 PM

May 8, 2009 at 5:19 PM

I start wrote my application before I find yours greate application, and WPF application is look better. WPF is future ;)

Can You tell mi how I add some point to map if I have PointLatLng ?

How You calculate scale ?

i see, i like some wpf features too! If you noticed wpf demo is with with testing markers, i wanna to make object list thread safe, but with wpf visible objects there is problem, any ideas?

I found code with add circle (metod worker_DoWork) and it worker for mi. I comment this metod and tray to add marker. I comment line

this.ItemsSource = Objects

and if add marker I add

GMapMarkerCross c = new GMapMarkerCross(this);

CurrentMarker = c;Marker show mi but I don't know how add another marker and how scale it.

AddMarker(CurrentMarker);

and in metod GMap_Loaded wrote

Core.StartSystem();

this.Items.Add(Canvas);

worker.RunWorkerAsync();

May 9, 2009 at 6:51 PM

please, wrote new release in this working week

May 9, 2009 at 7:11 PM

hi radioman,

 

i think i have a similar question.  i am using the control in to track vehicles, i would like a way of displaying a 'snail-trail'  of the route.  it is possible for me to build a route object?  i have lists of all the long/lat co-ords and wonder if the route object is simply a collection of these?.

also, i looked at your demo of the WPF screen, it looks interesting, may i ask what the application is you are developing ?

 

thanks

May 9, 2009 at 7:16 PM

some vehicle tracking application for my company, so as you see routing is working, just need to include some stuff in wpf control

May 9, 2009 at 7:16 PM

now, two peopel waiting for new release ;)

May 9, 2009 at 8:13 PM

well i am using WinForms..  pls , how do i construct a route object ? what elements are required.  what you are doing is exacly what i need to do also,

 

thanks,

 

May 9, 2009 at 8:14 PM

there is perfect example in demo, "Add route" button event

May 9, 2009 at 8:23 PM

right thanks,  i also just thought,  since we have the source code, then i can just see exactly how you plot the route.

thanks again,

 

May 9, 2009 at 8:25 PM

yeah, you can even oweride that function if you want draw yourself

manual route creation:

internal Path CreateRoute(List<System.Windows.Point> pl)

      {

         // Create a path to draw a geometry with.

         Path myPath = new Path();

         myPath.Stroke = Brushes.Navy;

         myPath.StrokeThickness = 5;

         myPath.StrokeLineJoin = PenLineJoin.Round;

         myPath.StrokeStartLineCap = PenLineCap.Triangle;

         myPath.StrokeEndLineCap = PenLineCap.Square;

         myPath.Opacity = 0.6;

 

         // Create a StreamGeometry to use to specify myPath.

         StreamGeometry geometry = new StreamGeometry();

 

         using(StreamGeometryContext ctx = geometry.Open())

         {

            ctx.BeginFigure(pl[0], false, false);

 

            // Draw a line to the next specified point.

            ctx.PolyLineTo(pl, true, true);

         }

 

         // Freeze the geometry (make it unmodifiable)

         // for additional performance benefits.

         geometry.Freeze();

 

         // Specify the shape of the Path using the StreamGeometry.

         myPath.Data = geometry;

 

         BlurEffect ef = new BlurEffect();

         {

            ef.KernelType = KernelType.Gaussian;

            ef.Radius = 3.0;

            ef.RenderingBias = RenderingBias.Quality;

         }

         myPath.Effect = ef;

 

         return myPath;

      }

 

      internal void SetNewRoute(bool Direction, int ScheduleName)

      {

         MainMap.Markers.Remove(currentRoute);

         lock(Trasos)

         {

            List<System.Windows.Point> pl = new List<System.Windows.Point>();

            var tt = from p in Trasos

                     where p.Direction == Direction && p.ScheduleName == ScheduleName

                     select p;

            var first = tt.FirstOrDefault();

            if(first != null)

            {

               currentRoute = null;

               currentRoute = new GMapMarker(MainMap, new PointLatLng(first.Lat, first.Lng));

               var pp = MainMap.FromLatLngToLocal(new PointLatLng(first.Lat, first.Lng));

 

               foreach(var i in tt)

               {

                  var p = MainMap.FromLatLngToLocal(new PointLatLng(i.Lat, i.Lng));

                  pl.Add(new System.Windows.Point(p.X - pp.X, p.Y-pp.Y));

               }

 

               var rt = CreateRoute(pl);                

               currentRoute.Shape = rt; 

            }

         }

         MainMap.Markers.Add(currentRoute);

 

         currentDirection = Direction;

         currentScheduleName = ScheduleName;

      }

Hi radioman

Did you do something about route in WPF ?

May 13, 2009 at 5:46 PM

you can add route as marker

May 13, 2009 at 6:26 PM

I think this solution, is it good way ? I thinking about I create a new shape for markers (it is route) and add in ItemSource. All object is in one sack. What do you think about this metod ?

May 13, 2009 at 6:28 PM

yes, thats what i've tryed to explain ;}

May 13, 2009 at 6:59 PM

May 13, 2009 at 7:00 PM
