How do I create a WPF Rounded Corner container?
...klight Controls (blacklight.codeplex.com) also have a nifty little control called ClippingBorder that also allows you to clip the content to your rounded corners. One nice thing about ClippingBorder is that it doesn't use a VisualBrush (which is one of the highest cost (in terms of performance) brus...
Storing custom objects in an NSMutableArray in NSUserDefaults
...ng protocol. Adding methods like the following should do the trick:
- (void)encodeWithCoder:(NSCoder *)coder;
{
[coder encodeObject:label forKey:@"label"];
[coder encodeInteger:numberID forKey:@"numberID"];
}
- (id)initWithCoder:(NSCoder *)coder;
{
self = [super init];
if (self !=...
Why would adding a method add an ambiguous call, if it wouldn't be involved in the ambiguity
...ong is completely unsurprising; the "ambiguous method" error heuristic basically picks any two methods from the candidate set if a best method cannot be determined. It is not very good at finding the "real" ambiguity, if in fact there is one.
One might reasonably ask why that is. It is quite tricky...
What is stack unwinding?
...the scope is of the function func.) This is done by the compiler inserting calls to destructors of automatic (stack) variables.
Now this is a very powerful concept leading to the technique called RAII, that is Resource Acquisition Is Initialization, that helps us manage resources like memory, datab...
Conveniently map between enum and int / String
...return map.get(num);
}
}
This solution is nice and doesn't require 'fiddling with reflection' because it's based on the fact that all enum types implicitly inherit the Enum interface.

what is the basic difference between stack and queue?
...t is the first one to come out. This is LIFO. Adding a piece of paper is called "pushing", and removing a piece of paper is called "popping".
Imagine a queue at the store. The first person in line is the first person to get out of line. This is FIFO. A person getting into line is "enqueued",...
The calling thread cannot access this object because a different thread owns it
...
To add my 2 cents, the exception can occur even if you call your code through System.Windows.Threading.Dispatcher.CurrentDispatcher.Invoke(). The point is that you have to call Invoke() of the Dispatcher of the control that you're trying to access, which in some cases may not be...
Why is the shovel operator (
...
Proof:
a = 'foo'
a.object_id #=> 2154889340
a << 'bar'
a.object_id #=> 2154889340
a += 'quux'
a.object_id #=> 2154742560
So << alters the original string rather than creating a new one. The reason for this is that in ruby a += b...
HEAD and ORIG_HEAD in Git
...or current branch. HEAD can also point directly to a commit; this state is called "detached HEAD", and can be understood as being on unnamed, anonymous branch.
And @ alone is a shortcut for HEAD, since Git 1.8.5
ORIG_HEAD is previous state of HEAD, set by commands that have possibly dangerous beha...
