I saw quite a few examples with maps around the net with
MapView.showsUserLocation=TRUE;
What would be the corresponding equivalent with message passing notation?
That depends on the property declaration. In the standard case when no custom setter is declared it is:
[mapView setShowsUserLocation:TRUE];
Note that you probably want YES instead of TRUE.

I have a view called 'selectView' in my postgresql database.
How i can get the results in to my server.js(nodejs code) like,
select * from selectView
Please suggest.
Sorry for the earlier mis-understanding. Didn't know node.js was server-side. A little search engine (you know the one) tells me that there's a postgresql library available for node.js. That should help you out.

That's the problem: I have to take an NSColor from the colorweel... how could I do? I tried declaring
NSColorWeel *weel;
But I don't know what to do next!
You could go read the docs?
Looks like you just call
- (NSColor *)color
to get the current color of the well, and
- (void)activate:(BOOL)exclusive
to activate it.

I have the following URL in a table and I am given the responsibility to develop a script to remove the dots around the date.
For example:
The Date: 2013.01.20 should be read like the following in the url:
http://local.website.net/doc/q?file=5448245&date=20130829&ref=65457
Note the dots for http://local.website.net should not be removed.
How I can get started on this?
DECLARE #doc varchar(500) = 'http://local.website.net/doc/q?file=5448245&date=2013.08.29&ref=65457'
SELECT SUBSTRING(#doc,0,CHARINDEX('date=',#doc))+REPLACE(SUBSTRING(#doc,CHARINDEX('date=',#doc),LEN(#doc)),'.','')

I have two NSArrays and I would like to change one object in the first NSArray with another object in the second NSArray.
This is what I tried to do, but with no luck:
[[arrrndwords objectsinindex:i] replace object in index:1 with:[arrword indexinobject:rndnum]];
It throws me out of the app when I run it.
The method you are looking for is:
- (void)replaceObjectsAtIndexes:(NSIndexSet *)indexes withObjects:(NSArray *)objects
but it is not available to NSArray because it's immutable, you should use a NSMutableArray.
[array replaceObjectsAtIndex:[NSIndexSet indexSetWithIndex:1] withObjects:[NSArray arrayWithObject:yourObject]]

I want to know what was the first version of GCC that supported Objective-C ?
Yep. I see this question as likely to be moved to meta or something.
But in any event, the answer you want is 1988.
(which I found by looking in Wikipedia under the "Popularization through NeXT" section)
