There is a DeleteResource API command you can use if you know the name of the resource.

Well I managed to get the code working, and can add text to the map as a
label for a point. But have a bit of an issue as a result. 

Because a user maybe adding more than one block of text to the map, I am
creating a unique feature source in the Library for each one (rather than
reusing one, as the buffer code does), but as a result I am now getting
loads of feature sources being created.

Does anyone know of anyway I can delete these feature sources (in code).
What I want to do is remove the layer from the map, and at the same time
delete any feature sources from the library - they all start with the same
word but then have a time stamp on the end to make them unique. 

Any help would be really appreciated =)

Thanks,

Bev
