New Post: Geojson support ?

Radioman, can you add geojson support?

Now I see you have marker, polygon, lines,

but for large amount of point or polygon(for example, I have 20k parcels, 50k home address), geojson is the way to go.

I also worry about the performance, how much polygon/point can be added to map without slowing down the response?

I got a message of BING that from middle of 2017 only the REST Service will be supported for getting images. Is this already implemented in gmap.net??

Hi,

This error is printed on every map tile when I deploy my app to client PCs. The target CPU is AnyCPU and the .NET framework is 4.0. On my development PC it works without problems.

I use GMap.NET 1.7.1. I tried to update to 1.7.5 but I get the same error. Now I cannot go back to 1.7.1 because I get this error when trying to install 1.7.1: "The change on C:...\packages\GMap.NET.WindowsForms.1.7.1\readme.txt cannot be undone because a file already exists at C:...\packages\GMap.NET.WindowsForms.1.7.1\readme.txt. The file must be deleted from disk for the undo to succeed.". Nothing works today... :-(

Could you please help me?

Thanks,

Stavros

The problem was caused by SQLite and specifically the SQLite.Interop.dll. I was using incorrect version of the file in setup.

I am very new to programming and am attempting to use this control. So far it is super easy. One item I am trying to implement is a lower zoom level (.5 vs 1.0). I have seen people make posts saying they are editing the GMapControl.cs file to accomplish this.

How do I edit that file? I can't find that file. I have added the control to my Visual Studio project.

Can anyone help a noob please?

New Post: Different Tooltip Stroke Color on different Overlays?

January 5, 2017, 11:02 am

I think this is possible and that I am just messing it up. My map has two Overlays (storesOverlay and trucksOverlay). The storesOverlay shows an icon but the tooltip text is not visible unless OnMouseOver happens. I add the markers and they are added to the storesOverlay. The trucksOverlay have tooltip text visible always. Those are added as trucks are added to the system (or updated).

The problem I am encountering is that the color of the tooltips are the same when a truck update is added. When the program launches, the store tooltips are correct. You can't see them until you mouseover. When you mouseover, they are the correct color (orange/floralwhite). But when a truck updates, if I mouseover a store, the colors are the same as the truck. So instead of orange/floralwhite I get the truck colors (blue/yellow) for the stores.

Can anyone help me figure out where I might be doing something wrong? Or are marker settings the same across all Overlays?

Here is the code I'm currently using.

'in form load I add both overlays and make them visible
myMap.Overlays.Add(storesOverlay)
storesOverlay.IsVisibile = True

myMap.Overlays.Add(trucksOverlay)
trucksOverlay.IsVisibile = True
'this is how trucks are loaded when they first update - after that I simply change PointLatLng
Dim truckMarker As GMarkerGoogle = Nothing
Dim oPointLatLong = New PointLatLng(truck.Latitude, truck.Longitude)
Dim myImage As Image = Image.FromFile(myConfig.appFolder & "images\" & truck.MobileImage, False)

truckMarker = New GMarkerGoogle(oPointLatLong, myImage)

truckMarker.ToolTipText = truck.truckName
truckMarker.ToolTipMode = MarkerTooltipMode.Always
truckMarker.ToolTip.Stroke.Color = Color.Blue
truckMarker.ToolTip.Fill = Brushes.LightYellow
trucksOverlay.Markers.Add(truckMarker)
'this is a Sub called LoadStoreLocations (completely separate from where truck markers are added/updated) .
'this is called when the program is first loaded.
Dim storeMarker As GMarkerGoogle = Nothing
Dim oPointLatLong = New PointLatLng(store.Latitude, store.Longitude)
Dim myImage As Image = Image.FromFile(myConfig.appFolder & "storePic.png", False)

storeMarker = New GMarkerGoogle(oPointLatLong, myImage)

storeMarker.ToolTipText = store.storeNumber
storeMarker.ToolTipMode = MarkerTooltipMode.OnMouseOver
storeMarker.ToolTip.Stroke.Color = Color.Orange
storeMarker.ToolTip.Fill = Brushes.FloralWhite
storesOverlay.Markers.Add(storeMarker)

New Post: Prevent Markers from being moved on the map

January 10, 2017, 11:31 am

Hi,

I am creating an app that uses markers to show the current position of an object based on GPS.

The issue that I'm having is that whenever a marker is left-clicked on, the marker moves about 10 pixels. I am using the CustomRedMarkers that are in the WPF demo. My guess is that the marker location is being moved by the amount of the marker offset, but I can not find a way to disable this behaviour.

What I would like to have happen is that when the marker is clicked, a detail pane is shown for the object which that specific marker represents.

Thanks.
