Mapping Windows drive path to a RESTful API for cental file storage
Is this possible? Is there a programme that will allow this to happen? I have a program that needs to access a lot of data from a central storage, but the likes of Amazon S3 only allows access via RESTful API which is no good for this program. Only UNC or drive letters are acceptable... Help! Bernard ...
Help using MFC CMap (or std::map) please.

Mapping COM VARIANT Types to actual types using a map
I am writing a COM wrapper for a COM object that sends different types of values from a client and want to map these types in a Map to their actual C++ type, such as VT_BSTR to a wstring, etc. I was thinking of defining an enumuration of all COM Variant types and then using a map to have that Enum as the key and the actual type containi...
displaying tiled map in Gtk+ app
Hi I am about to embark on a project that will involve a GUI application that will need to display a map interface, generated from a global map tile cache (on local disk) at different levels of zoom. The app will be written using Gtk, and while I am fairly familiar with the basic Gtk widgets, I am unsure how to approach the map interfa...

Fast hash for std::set<int> of two values?
I am using a std::set<int> for the key of a std map (std::unordered_map<std::Set<int>,float>). I need a hash for this set. The set will always be only two integers, whose values could be up to 2 million. Any ideas on a good and fast hash for such a key as performance is critical? ...
Java Map::hashCode() collision - why?

Efficient pointer to integer mapping and lookup in C++.
I want to map pointer to integer for purpose of serialization. The pointers may be of different types and may point to polymorphic objects possibly using multiple inheritance. I need to query the map to know if the pointer is stored in it and if it is, then what is the associated integral value. What is the correct way to do it? The si...
Map<String, Map<String, Boolean>> myMap = new HashMap<String,HashMap<String,Boolean>>();
Why doesn't that work in java, but this does Map<String, Map<String, Boolean>> myMap = new HashMap<String,Map<String,Boolean>>(); Just to clarify the below alteration of the nested HashMap shows a compiler error, whereas the above does not not; with a Map (not hashmap) Map<String, Map<String, Boolean>> myMap = new HashMap<String,Hash...
[cocos2d-iphone] Infinite maps/scrolling question
I'm using cocos2d for the iPhone to create an infinitely scrolling horizontal tile map. To achieve this, I've generated a library of 'segments', which are basically horizontal chunks of levels that I randomly choose from and append to the end of that particular levels tile map. When tiles scroll off of the left of the screen they are rem...

Implementing a map_keys_iterator by derivation: a single compiler error
Hi everyone. I was working again with C++ during the weekend and came to notice something that I'm not sure where does it come from. Following the advice in this thread, I decided to implement a map_keys_iterator and map_values_iterator. I took the -- I think -- recommended-against approach of deriving a class from std::map<K,V>::itera...
