I was toying with a mock up which calls the Yahoo! weather service and
displays the info in WebView in a separate window. All was dandy but I
started noticing that upon the first invocation to fetch the weather, I
get a Debugger trap:

I have a program which needs to run under 10.4, but I used a method that
is only defined for 10.5. No biggie, it was easy enough to replace it
with something that works for 10.4. The problem is that I didn't find
this out until I ran the app under 10.4. My apps deployment target ...

I know nothing about programming. How difficult or easy is it to write
an App for Mac OS X. Obviously I know the complexity of the App will
have a lot to do with it. But is it as simple as going through a good
tutorial book or does it require years and years of training/learning?

goal - create an array of bytes that matches a font files data
obtained from an ATSUFontID
First off, I have seen a number of types of font types including
ATSUFontID, FMFont, FOND, ATSFontRef, CTFontRef, but nothing really

I have a library that requires either a path to a ttf file or the raw
data that is contained in a ttf file.  I would like to get this data
from an ATSUFontID for an installed system font.  Is this possible on
a Mac?

I'm fiddling with a small Cocoa app that needs to read/write a file to
an FTP server. But I do need to send a username and password to the
server. The data lives in an NSData.
Is there any simple sample code to do this?

In my app's preferences window, I have two labels, two checkboxes, a
textfield and an nscolorwell all bound to values in an
nsuserdefaultscontroller. Values are saved and restored as they should
be -except- when the prefs window in cancelled. Here's what happens:

I'm trying to figure out persistent storage types where like the sample
at least (EventManager), can store binary, sqlite or xml data. It does
this using all built-in functionality i.e., there's no user code (aside
from what's hidden inside NSPersistentDocument). I would like to ...

In Mac OS X 10.4.11 I am having a problem with ActiveTCl's
8.4 graying out certain .TCL files when I try to select

Does anybody know, when I click on a .app (such as Safari.app) bundle,
how does the system know which file to execute? I mean, I looked under
Contents/MacOS/ sometimes there are alot of executables in there...
which file tells the system (launchd? finder?) which executable file

I have a tableview, whose rows are fed by drag-n-drop from another
table, with its delegate routines for such, but no data source outlet;
the columns are individually bound to their array controller.
All's well until I try and delete. I had been toying with the idea of

I'm trying to do an app that will talk to a web server. Got the "talk
and listen" stuff working fine, but I've hit a problem - The server
answers back with a gzipped payload - I can parse the headers and find
the start/end (and therefore, the length) of the gzipped data that I'm

I know this is a long shot, but would anyone happen to have the
CodeWarrior Pro 5 and 6 updates? Unfortunately Freescale only hosts
updates back to CW Pro 7. CW Pro 5 was the last version that ran on 68k
macs, and Pro 6 was the last version that generated 68k code.
