I have inherited some plain old C code written back in '94 that uses
only floats. I did a little empirical testing on my Mac (2 x 2.8 GHz
Quad-Core Intel Xeon) to see whether it would be worthwhile to change
everything to double. I would like the greater accuracy, but don't

I can't seem to get sscanf to work for some odd reason on my Macbook
Pro. The following code:
sscanf(string, "%f", &double_var);
Doesn't do as expected. According to gdb, double_var goes from 0.0

I've made a C++ library and would like to develop some unit test for
it. Do I need to make an executable to use unit tests or can I write
them against my dylib?
Also, what does it mean in the tutorial (http://developer.apple.com/

Deep in the guts of my program, I've got a standard
"http://host.network.TLD/whatever/something/foo/pagename.html" URL to a
web page stored in an object. Where it came from, how it got into that
object, and what type of object it's in is irrelevant - Just take it as

I wrote following code. Also, I have created com.p1.myapp.plist from
admin user at /Library/Preferences and has 666 permission.
SInt kColor = 5;
const CFStringRef kAppName = CFSTR("com.p1.myapp");

I just purchased VMWare's Fusion and am intending on using Windows XP
through it. I have been using the trial version for a couple of weeks
and really enjoyed it. I have an iMac and plan on using a USB external
hard drive to host all my Windows files and projects. Can you suggest

I have two Happy Hacking Keyboard lite2 for the Mac that I think are
great. There is one minor problem. There is an intermittent problem
while using the keyboard either the Mac G4 (Tiger) or the Mac Pro
(Leopard) where it will switch to caps on. I try the function+tab key

Humor my OCD :)
I have a method (as part of a category adding on to NSMutableData) I'm
trying to name in a "by the conventions" fashion. It works fine -
nothing wrong there. I just don't like the way the method declaration,

This is my first time compiling objective C and C files together for
one program. All of my files are C files except the main file which is
in objective C called main.m
Here is the code for my boilerplate main implementation file file:

Obviously from the subject line I am a developer. :)
I would like to know if anyone out there has had experience using
VMWare on iMac with XP with the XP VM running Oracle 11g or any
version for that matter and/or running SQL Server as well. They don't

Why does Dashcode report the error "Value undefined (result of
expression widget.system) is not an object" when it comes across the
line below?
var output = widget.system("/usr/bin/which ls", null).outputString;

When I build, say, an objective C application or a C++ application,
how do I access the compiler build output ie: the output from the
compiler that goes on when something is compiled and linked. I'm
curious about the steps XCode takes to build my program, ie: the

I have a plug-in (a .bundle) that is linked against a dynamic lib I
wrote. Everything works fine on my machine. The only problem is that
now, I want to distribute it. Problem, I would like to make it very
simple. For the moment, the .dylib has to be in the /usr/local/lib

I have sent one post in this group long before. Issue was my
application was not able to bind on port.
Senerio was one client was connected successfully and then I close the
application and If I switch the user and try to bind the the port on

The CocoaDev site that Reinder pointed me at was *VERY* useful - At
least now I think I've got the beginnings of a grip on how to use
NSTableView.
Except for one minor detail...
