Continuing the discussion from [How to draw a circle in MapwinGIS](https://mapwindow.discourse.group/t/how-to-draw-a-circle-in-mapwingis/977):

Hello

1. I want to calculate the distance between the two icons on the map, without drawing a line.

1. I want to show the angle between two icons by drawing a line on the map. It is exactly like the map ruler, but instead of calculating the kilometer, show us the angle.

1. I want to show me a message box when I click on the icon on the map.

2. I want to display the offline map of a city or country like google map in the application. Please help me to implement the offline map.

Please help me in these cases.

It is best to limit a topic to 1 question.  
The get the distance between two shapes use [Shape.Distance()](https://mapwindow.org/documentation/mapwingis4.9/class_shape.html#aa19e42ae98e0ea0d98ccc30939c1c3ea)

You can also have a look at the [Measuring Class](https://mapwindow.org/documentation/mapwingis4.9/class_measuring.html#details)

You can use the [AxMap.SelectionChanged](https://mapwindow.org/documentation/mapwingis4.9/group __map__ events.html#gaddcf7e72b3cb42cfdc7a4f6447964658) event to open a message box.

In [MapWinGIS v5.3](https://github.com/MapWindow/MapWinGIS/releases) the pull request [PR-146](https://github.com/MapWindow/MapWinGIS/pull/146) was implemented. Making offline tiles possible.

> BaseProvider modified to allow URLs like `file:///c:\temp\maps{zoom}{x}{y}.ext` and offline tile loading from filesystem.
