HashMap seems as good as any other - so just use that .
String>();
Since Map is an interface, you need to pick some class that instantiates it if you want to create an empty instance.

Take a look at NSValue :
[pSampleMap setObject:[NSValue value:&sObject withObjCType:@encode(sSampleStruct)] forKey:[NSNumber numberWithInt:nInt]];
Also, you're having a memory leak in [[NSNumber alloc] initWithInt:nVar] and you're code will not even complile... .

Since the iPhone doesn't support Flash (thank God. Waiting for HTML5 universe!), how do you create clickable maps with hotspots or zones that change colour with a mouseover event?
Like this Flash mp here.

In fact, it's inherent to the use of a touch screen .
Got something like this in the examples
Rest assured that you don't have a mouseover event in Mobile Safari .
In case you are using html as the output format a lib like RaphaelJs could help you .

I'm building up results by joining tables
select t1.*, t2.col2 from t1, t2 where t1.col1=t2.col1
Is there a way to create a temporary 'mapping' table 'inline' in a select statement for instances where the t2 table doesn't exist?
So something like

Don't know whether it works in Oracle, but are you looking for something like the following pseudocode?

Say I have a collection of maps:
(def coll #{{:name "foo"} {:name "bar"}})
I want a function that will add an id (a unique number is fine) to each map element in the collection. i.e.
#{{:id 1 :name "foo"} {:id 2 :name "bar"}}
The following DOES NOT WORK...

How about
(defn add-unique-id [coll] (map #(assoc %1 :id %2) coll (range (count coll))))
Or
(defn add-unique-id [coll] (map #(assoc %1 :id %2) coll (iterate inc 0)))
If you want to be really, really sure the IDs are unique, use UUID s.

This is a technique called Treemapping.
Very easy to use.
I've used these charts before with ASP.NET and C#.
Heres some examples of their heat maps .
The charting tools provided by http://www.anychart.com/ are really good for this .

I'd like to initialize a map - object "id" with identities from 0 to n-1, i.e.
id[0] = 0 id[1] = 1 . . id[n-1] = n-1
Is there a simple way - a one-liner, a method inside the map-object, simply something really simple - that does that?

Are you sure you cannot use a vector? Doing so .
You could use the
template <class InputIterator> map(InputIterator f, InputIterator l, const weird to use a map with the key being a simple index.

Luc is right - I just tried that in gvim (well, MacVim) and it worked... .
I've given up on vim, and I systematically use gvim for that reason .
Vim keybindings are limited by the terminal we are running vim within .
I suspect you are using vim and not gvim.

I changed your whole code so]); map <string, vector<int> > myMapOfVec; string KEY; if (acemblyfile.is_open()) { while.
You should use the vector in the map instead of creating one yourself.
