I'm trying to make a wrapper to the STL map container, in order to add a const method to return the value given the key. In map, operator[] isn't const, and find() requires dereferencing to get the value (map.find()->second). I'm basing some of my "research" off of http://stackoverflow.com/questions/152643/idiomatic-c-for-reading-from-a-...
Hey fellas, What is a neat way to hold pairs of strings which are not necessarily key-values (might have duplicate keys), for a small collection? List[List[String]] works obviously but looks dirty. Cheers Parsa ...

The user should be able to place the items at any location inside of the designated workspace, should be able to rotate them, and after placing the object, they should be able to ...
Hi guys, I'm currently working on a C# application. What I would like to do is display a map of the UK, just a JPEG image (if possible), which also, when clicked, generates geographic coordinates of the point clicked. Ideally what I would like to move onto is displaying a marker at two points clicked with a line drawn between them but ...
Hi, I've written a small Groovy script that exposes a very weird behaviour. can anyone explain it ? // Creating a groovy map def map = [:] // Putting a value in map["a"]="b" // Render it without trouble println map["a"] // Putting another value in (yup, this one has THE name) map["metaClass"]="c" // Failing to render it println m...
In my actual project I need to draw a MapView with a given running/walking/cycling path on top of it. I don't need the current position so I added an overlay just for the path (no MyLocationOverlay). The path is painted but I don't see the Map in the emulator - only the grey tiles. The apiKey is set in the layout (MapView) and INTERNET ...
I try to populate the content of a c++ map within a loop scope. #include <set> #include <map> map<int, set<int> > maps; for (int i=0; i<10; i++) { set<int> seti; // content: a set of integers seti.insert(i); seti.insert(...); maps.insert ( pair<int,set<int> >(i,seti) ); } The question is: does maps.insert copy the pa...
Hey, I have several lists that I would like to map together, but I can't quite work my head around how to do it. I am scraping a live feed of Horse Racing results. The feed only lists the course/time once and three horses and their positions (top three) OR four horses and blank (i.e. "") positions IF the race was abandoned. These are t...
Hi, We have floor plans of a building in png format. I want to provide Google Map API( or any better Map solution) to the client to locate the buildings from a world map. The requirement is when the user clicks on a building, it has to load my floor plan of the building in the canvas. I was looking into overlays and mashups. Not able to ...

Hi, It's my first time trying out C++ STL. I'm trying to build a multidimensional associative array using map. For example: typedef struct DA { string read_mode; string data_type; void *pValue; void *pVarMemLoc; }DA; int main() { map<string, map<string, map<string, map<string, map<string, DA*>>>>> DATA; ...
I've got a Map<String, Person> (actually I'm using a more complex POJO but simplifying it for the sake of my question) Person looks like : class Person { String name; Integer age; //accessors } How can I iterate through this map, printing out the key, then the person name, then the person age such as : System.out.println(St...
It looks like -- in Scala 2.8.0 -- if you map() a Map instance to a sequence of 2-tuples that you end up getting a Map back. When this happens, any of the 2-tuples with the same first element are considered duplicates, and you only end up getting the last one. This is different from what happened in 2.7.7. This is easier to understand...
