I got the latest source and just tried to compile and i am getting errors. Seems to be something about class names or name spaces.

Commented Unassigned: I get a blur image of map on button click [16098]

I m working in winforms using C#.net.
I get a latitude and longtitude from an device and plot the value in the map.
Initially i loaded the map in initialize component(),It is showing me correctly.
But when i used in the button click event, map is getting loaded,it is showing me an blur images.

The code i used in button click event:-

try
{
GMap.NET.GMaps.Instance.Mode = GMap.NET.AccessMode.CacheOnly;
gmap.MapProvider = GMap.NET.MapProviders.BingMapProvider.Instance;
GMap.NET.GMaps.Instance.Mode = GMap.NET.AccessMode.ServerOnly;
// gmap.SetCurrentPositionByKeywords("Mumbai, India");
GMapOverlay markersOverlay = new GMapOverlay(gmap, "marker");
GMapMarkerGoogleGreen marker = new GMapMarkerGoogleGreen(new PointLatLng(ObjParse.latitude, ObjParse.latitude));
gmap.Position = new PointLatLng(ObjParse.latitude, ObjParse.latitude);

markersOverlay.Markers.Add(marker);
gmap.Overlays.Add(markersOverlay);
gmap.MinZoom = 1;
gmap.MaxZoom = 50;
gmap.Zoom = 18;
marker.ToolTip = new GMapRoundedToolTip(marker);
marker.ToolTipText =Convert.ToString( ObjParse.latitude)+","+Convert.ToString(ObjParse.longtitude);
}
catch(Exception ex)
{
log.Info("Error in Map plot Button"+ex.ToString());
}

please help me to solve it.
Thnk's in advance

Commented Unassigned: Fix for smooth MapPoint animation in WPF [16097]

≪ Previous: Commented Unassigned: I get a blur image of map on button click [16098]

If animating the MapPoint property in WPF, the map stutters to the target point. Also, the overlays and the map moved with different behaviour.

With the following fix the MapPoint Animation will be smoothed:

In GMapControl.cs, function OnMapPointPropertyChanged.

Replace the line:
```
(source as GMapControl).Position = new PointLatLng(temp.X, temp.Y);
```
with the following lines:
```
GMapControl map = (source as GMapControl);
GPoint centerPixel = map.Core.Provider.Projection.FromLatLngToPixel(map.Core.Position, (int)map.Zoom);
GPoint targetPixel = map.Core.Provider.Projection.FromLatLngToPixel(new PointLatLng(temp.X, temp.Y), (int)map.Zoom);

map.Offset((int)(centerPixel.X - targetPixel.X), (int)(centerPixel.Y - targetPixel.Y));
```

Additionally, to make it work also with fractional zoom Levels:

In GMapControl.cs, function void Offset(int x, int y):

Replace the line:
```
UpdateMarkersOffset();
```
with the following lines:
```
if (IsRotated || scaleMode != ScaleModes.Integer)
{
ForceUpdateOverlays();
}
else
{
UpdateMarkersOffset();
}
```

Would be great if you want to take this into your main branch.

Comments: thanks

Commented Unassigned: Drag Item [16078]

≪ Previous: Commented Unassigned: Fix for smooth MapPoint animation in WPF [16097]

On mouse move evenhandler when we drag a item over
other one we lost it and often the drag stop:

In the GMapControl.cs I add this boolean

public bool markerAsClick = false;

The caller setup the flag

void MainMap_MouseMove(object sender, MouseEventArgs e)
{
if(e.Button == MouseButtons.Left && isMouseDown)
{
if(CurentRectMarker == null)
{
if(currentMarker.IsVisible)
{
currentMarker.Position = MainMap.FromLocalToLatLng(e.X, e.Y);
}
}
else // move rect marker
{
MainMap.markerAsClick = true;
PointLatLng pnew = MainMap.FromLocalToLatLng(e.X, e.Y);

. ..
......
}

MainMap.Refresh(); // force instant invalidation
}
}

protected override void OnMouseMove(MouseEventArgs e)
{
if(!markerAsClick)
{
.........
..............
}

base.OnMouseMove(e);
}

for me it's work fine
but probably you have a better place to do this
Comments: thanks i'll check it

Version: 1.7.0.0 - C# - Winforms - Visual Studio 2012

I'm having problems drawing circles on my gMapControl1.

I found this: [http://greatmaps.codeplex.com/discussions/220983] but Visual Studio does not like:

Overlay.Control.Core.Projection.GetGroundResolution(Overlay.Control.Zoom, Position.Lat)) * 2;

It does not know about "Core"

I need to draw several circles 50 miles, 100 miles, etc. out from a certain position.

Thanks

Bearing was not working at least since 1.6. I'm not sure if I'm doing it correctly but now ti's working for me.

since it's only in 1 file, I'll paste the diff here.
