I hava defined my container like this:
	struct name{};
	typedef multi_index_container<
	    	BOOST_MULTI_INDEX_CONST_MEM_FUN( Texture2D ,std::string, getName)
	> TextureContainer;

the problem is that the tutorial and the examples that the boost library provides havn't answerd how would i go about deleting a shared_ptr from the container and what would be the best way of searching and retrieving a shared_ptr from the container.

Central to the concept of the multi-index container is that of 'views'.

You search by getting a certain view into the container, so in this case you'd do the following;

TextureContainer myTextures;
typedef TextureContainer::index<name>::type textureByName;

textureByName &name_idx = myTextures.get<name>();
textureByName::iterator it = name_idx.find("sometexture.jpg");

if(it != name_idx.end())
// we have a texture!

Based on what you have however I'm left to ask why a MI-Container, why not a map of some sort? (the Boost svn has a hashmap in it now iirc)

at first it was a hashmap. but i thought that a hashtable would be faster.
Google said that i could implement a hashtable using a multi_index_container so i thought i should try it to see how it works
