I am developing one application in that i want to add device request feature ,for that i
am sending a message like "DeviceRequest" .
if this message is send to other pc in that pc it shows one Alert message
(NSRunAlertPanel(@"Request",@"Please Disconnect the device",@"ok",@"",nil);

I've searched around and I can find sample code for this simple Bindings
problem:
I have an NSMutableSet of strings. I update the set internally. I want to
display a single column NSTableView with all the current strings in the
set. These strings can (and do) change as the program runs. Fr

Looking at the source for AsyncUdpSocket I would put a break point on -
maybeCompleteCurrentReceive
and see if this method is called multiple times.

Hello,
I'm trying to set up a date formatter to convert a date string I receive from a
server when downloading and sync'ing notes from web app. The dates I receive
look like this:

The API docs for this web app specify that this is in GMT time, technically

Hi Quincey,
Thanks for you help. I am trying to pass the class reference around for drag
and drop, I think i'll try your idea of converting the pointer to a number,

Maybe you could grep your xib's for NSWindowStyleMask, look at the output, and
AND the values with 0x10.

Found it -

A couple of points on the code:
(1) If you're concerned about size, store the IDs in NSData instead of
NSString. That way you get the full 8 bits per byte instead of 6, and
avoid the complication of translating to and from ASCII.
(2) If you do need to convert to string, it would be safer to

Hello. Quick question.
I'm using NSDrawThreePartImage and for the most part it works. But
when the height of the views changes it's scaling the left and right
edges. I'm just not sure if it's supposed to be doing that?
Here are some images to see what's happening:

Thanks Quincey.
removeObjectAtArrangedObjectIndexPath works but remove: still does not. It
should remove the object, if there is a bug then I will file a bug report.
anyone have ideas as to why remove: may not be working. I hate to find another
way and drop a possible issue/bug. Thanks.
