NSSearchField and Dates
Hello folks, This question is a bit simplistic, but I’m not having luck finding an explanation. This is my first time using NSSearchFields. I’m in the process of binding them to an NSArrayController of data from a previous developer. So far, so good for the most part. However, one of the values to query is an NSDate with the key of “Start Date” (there is a corresponding “End Date” value). How do NSSearchFields interact with NSDate values? What would be the appropriate way to handle this? If I write a dateformatter and add it to the ValueTransformer, does the search field query against that? thanks for any info, Jaime ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Trigger nextkeyview based on NSTextField input length
Hello folks, I'm writing a license key input window. The license key is broken into four parts, separated by "-". I've created four NSTextFields for each component of the key to aid typing and identification (e.g. NSTextField1 - NSTextField2 - NSTextField3 - NSTextField4 ). The textfields utilize a NSFormatter subclass. What is the most appropriate way to trigger nextkeyview after x number of characters in the textfields? I'd like for the user to get forwarded to the next textfield after typing the appropriate number of characters in the current textfield. This is a common practice in license key windows. Should I put it [[inputField window ] selectNextKeyView:self] in the formatter subclass? Do it in the window controller? thanks for any thoughts, Jaime Magiera Sensory Research, Inc. http://www.sensoryresearch.net ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

In short, that's really a bummer. It totally negates a chunk of functionality from my framework.

That did the trick. Thanks!
if((strcmp([aNumber objCType], @encode(int))) == 0) {
NSLog(@"It's a int");
} else if((strcmp([aNumber objCType], @encode(float)))

How tell tell if an NSNumber was initialized from a float or int?
Hello, The list search keeps timing out for me, and web searches are not finding anything. I can see how to tell if an NSNumber was initialized with an int or boolean (NSCFNumber vs. NSCFBoolean).

The project did originally start out writing to temp files for these processes. However, I got a complaint from a customer about the disk footprint of temp files. So, I tried going the other route.

NSFileHandle or a better way?
Hi folks, I've been using NSFIleHandle for a project that inserts data into a file and synchs it back to disk. Everything went smoothly until the app started getting used for larger files ( > 200 megs). First, I ran into the NSFileHandle -> NSData 256 megs conundrum. That was solved by, as others suggested on this list in other threads, iterating with readDataOfLength or availableData instead of a single readDataToEndOfFile. That worked well. I've got pools set up to keep the memory down. The problem now is that the reads are still really slow. For example, with a read length of 50 megs, I can only get in 3 reads per second. My apps ends up taking almost a minute to perform all of its functions on a file of 500 megs. Perhaps my overall approach was wrong to start out. What I've been doing is opening a file handle, copying the data after the insertion point to an NSData, truncating the file handle at the insertion point, adding the new data, then adding back the trimmed data. This works fairly well if the insert point is towards the end of the file. However, there are instances where I need to insert a few hundred kb into a the file at a location only a few hundred kb into the file. xxx ^ x The time hit comes from copying the trim data to the NSData. Is there a better way to do this with NSFileHandle? Is there a better way to do this than NSFileHandle? thanks for any thoughts, Jaime Magiera Sensory Research http://www.sensoryresearch.net ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Hello Joeless, Yes, people have used Cocoa/MacOS X to decode analog phone and radio transmissions. In particular, 2600 hz ;) You can write a CoreAudio AudioUnit to accomplish this. In general audio parlance, you would use an FFT to determine the frequency of the sound.

Is there something similar I can do here or some other way. Hi, I don't have an answer to your question, but an observation: Giving a user the option to click something, then telling them they cannot, seems kind of weird. Radio buttons are generally for options a user has. If the functionality denoted by an item is unavailable, generally it is hidden or at the very least inactive. In other words, using logic to determine availability of an interface item before it is clicked. Such a thing can be done with bindings. anyway, good luck finding the answer to your question.

which choice to implement iterations on separate threads
Hello, I'm trying to get a sense of what folks are doing for applications with individual threads for pulling samples at timed intervals, updating UI, etc. Looking over the docs, the options are NSTImer, NSThread and the new NSOperationQueue. At a casual glance, NSOperationQueue doesn't have any scheduling. There are a couple ways to ostensibly add it. Not ideal though. NSTimer seems like a bad choice due to the dropping of an iteration if the previous isn't completed. Not good if the called method takes a little longer than expected (found this out the hard way). This leads me in the direction of using an NSThread with either an NSTimer in it or utilizing a while() with the new sleepForTimeInterval or some other delay within. Is this is a reasonable understanding of the situation for Cocoa? What are folks generally using for timed actions on separate threads?
