I have a Javascript Object like
var obj = {
key1: 'value1',
key2: 'value2',
key3: 'value3',
key4: 'value4'
}
How can I get the length and list of keys in this object.
Hey, I'm trying to write a program in C# that will track the pressing of certain keys (using a keyboard hook), and send different ones instead.
For instance, when I press the A key it will instead send the Q key.
I used http://www.codeproject.com/KB/cs/CSLLKeyboardHook.aspx this for my hooks and tried to use the SendKeys function, but I get an exception about the garbage collector destroying some object inside the hook class.
Any ideas why Xcode wont let me define a c++ class in my cocoa project?
I am trying to use a C++ class in my cocoa project but I am getting build errors just creating the c++ header file.
class SomeClass{
public:
int count;
}
Expected '=', ',', ';', 'asm' or 'attribute' before 'SomeClass' in .....
If I remove all code from the header file, ?the cpp file builds without any errors and is included in the list of compiled sources...
Hi
What are the possible ways of representing data in memory in .Net (or in general)?
It would be great if data could be sorted and looked up by key (or multiple keys).
We are thinking to use collections, arrays, list of collections/arrays. One object would be in several collections (one sorted asc, other desc, etc.).
Maybe this is not a good idea, and we would like to hear some other possible solutions.
Thank you

CGRect type is a structure type. If I want to define a property as this type, should I use assign or retain attribute for this type?
@interface MyClass {
CGRect rect;
...
}
@property (nonatomic, assign) rect; // or retain?

I recently tried a lot of different stuff with lightweight migration. These all work:
1) Rename attributes (with renaming identifier specified)
2) Add attributes
3) Add new entity + new attribute + inverse relationship to an already existing entity
4) remove existing entity + relationships to that entity
= It almost looks like just about anything can be handled with LM. Did I miss something? In which cases am I getting into trouble and need an some more complex approach?
I was psyched about the possibility of using SQLite as a database solution during development so that I could focus on writing the code first and dynamically generating the db at runtime using NHibernate's ShemaExport functionality. However, I'm running into a few issues, not the least of which is that it seems that SQLite requires me to use Int64 for my primary keys (vs, say, Int32 or Guid). Is there any way around this?
I have an NSDictionary object that is populated by NSMutableStrings for its keys and objects. I have been able to change the key by changing the original NSMutableString with the setString: method. They key however remains the same regardless of the contents of the string used to set the key initially.
My question is, is the key protected from being changed meaning it will always be the same unless I remove it and add another to the dictionary?
Thanks.
Im building an app in c# using WPF and i need it to bind to some keys. Ive found some links but not work well with my setup. Anyone done this before?
also if i could bind to the windows key would be great.
I need to retrieve all the records in a table with nHibernate. If I had the key for all the records in the table I could loop and use nHibernate's Get method (this seems inefficient though) but I don't have the keys. I could also use FindAll but this requires criteria or a stored procedure.
How can I get all the records from the table?
I'm creating an iPhone app for a client who's not comfortable with allowing users the ability to press the menu & hold keys to take a screenshot of the app content. Is there any API to block this while the app is running?

In JSF, we can bind HtmlDataTable to backing bean and get the row data. But ui:repeat doesn't even have a binding attribute. So, how do I know which row (element) is clicked in ui:repeat?
I'm using jQuery UI's slider to update a div containing a number. Dragging or using the left/right keys should only allow the user to choose a number between 1 and 5 (this works as intended). However, if the handle has focus and I use page up/down, I start to get rounded values that are well out of the range of 1-5. Anybody experience the same? Thoughts?
For my Contact class, the property EmailAddress is marked with the [DataType(DataType.EmailAddress)] attribute.
In my view, using Html.Display("EmailAddress") and Html.DisplayFor(c => c.EmailAddress) yields different results. The former outputs a mailto: link, which is the expected behavior, while the latter simply outputs the email address as plain text.
My question is why the different behavior, I expected these two methods to have the same output.
I am sorting a hash in Perl. I encountered an Out of memory error when running my Perl Script:
foreach $key (sort (keys(%hash))) {
....
}
How do I sort a hash that has tons of data?
I was wondering how Java sorts items in the Map (HashMap or Hashtable) when they are added. Are the keys sorted by the hashcode, memory reference or by allocation precedence...?
It's because I've noticed same pairs in the Map are not always sorted in the same order
A class has a constructor which takes one parameter:
class C(object):
def __init__(self, v):
self.v = v
...
Somewhere in the code, it is useful for values in a dict to know their keys.
I want to use a defaultdict with the key passed to newborn default values:
d = defaultdict(lambda : C(here_i_wish_the_key_to_be))
Any suggestions?

I want to do a effect like the switching windows from Win 7 [Win]+[Tab] keys pressed.
I created two "windows" (movie clips) and when I click on the 1st it displays on top of the other, but the problem is when I click on the 2nd I can see the 1st one displayed in it. Is there any way that i put a movie clip on top of the other.
Thanks
