I'm trying to create a button using VB.NET and ArcGIS 10 to clear the layers of my data frame.

I know how to add layers, but I don't have any idea on how to delete/clear them.

Any suggestions?

Thank you!

The easiest way is to cast the Map to IMapLayers and call the IMapLayers.ClearLayers method.

How can I call IMapLayers.ClearLayers? Thank you – TitoGIS Dec 12 '12 at 11:12
Perhaps at this point it would help you to start with some high-level ArcObjects documentation on your own. The overview for esriCarto library contains lots of information that will be beneficial in your case. – Petr Krebs Dec 12 '12 at 13:18
Also the Working with the map article could help you. – Petr Krebs Dec 12 '12 at 13:20

Great, you can learn a lot by browsing the documentation. Note you can also call DirectCast(Map, IMapLayers).ClearLayers() in VB.NET, where Map is an IMap variable. C# equivalent is ((IMapLayers)Map).ClearLayers();. – Petr Krebs Dec 12 '12 at 19:41
