I'm writing a Cocoa application that installs itself as an menulet in the menu bar (i.e. like the volume or battery icons). When the program crashes, it isn't possible to use the Force-Quit dialog, because it doesn't show up in the list. Of course, I can still kill it using the command-line, but my users don't know how to do that. Is ...

Hey, I am sorting stores to get the closest stores. Furthermore I want to know how far away this shop is. The SQL query would look like this: select *, 6371 * 2 * ATAN2(SQRT(POWER(SIN((RADIANS(?) - RADIANS(latitude))/2),2) + COS(RADIANS(latitude)) * COS(RADIANS(?)) * POWER(SIN((RADIANS(?) - RADIANS(longitude))/2),2)), SQRT(1-POWER(SIN...

I am building a dynamic form in a Cocoa application and am planning to use the NSForm object to add entries to it from an array. Some of the entries require a text input, but some require a boolean input (i.e. a dropdown list), and some even require a file input (i.e. a place to upload an image or a movie or sound file). It seems that ...
Sitution: Newbie with interface for a music app. I have 2 large images, one the master 'up' or normal view, the other the complete 'down' view. (Buttons all pressed, lit, etc, LED's on, etc). Might have a couple smaller images as well to copy over. In Carbon, and old Mac OS, I would load up 2 GWorlds with each image, then use Copybits t...

I'm trying to compile a version of convert (one of the ImageMagick tools) for distribution with a Cocoa app I'm writing, and I've mistakenly bundled a version that relies on shared libraries my users don't have (twice, already). Thus, I'm trying to pare down the list. After stripping out everything I didn't need, running otool -L conve...
When reading an NSString from a file I can use initWithContentsOfFile:usedEncoding:error: and it will guess the encoding of the file. When I create it from an NSData though my only option is initWithData:encoding: where I have to explicitly pass the encoding. How can I reliably guess the encoding when I work with NSData instead of files...

Hi there, I have a call to a third-party C++ library which I have put into its own thread (currently using NSThread). I would like to give the user the ability to stop the execution of that thread. (I am well aware of all the problems this might cause, but I still wish to do so.) According to Apple's Thread Programming Guide, there ar...

Has anyone else seen or heard of any issues with NSTask in 10.6? This code worked fine yesterday, and is not working today. NSTask *task = [converter task]; [task waitUntilExit]; NSLog(@"Task did complete"); The task does what it's supposed to do (I checked the output and it's fine), but the program will wait indefinitely at the wait...
