Probably I don't understand something essential !! The following
thing happens : I pick up NSString from other NSString and put it
into NSMutable array. The initial NSString is different from what I
store in the array.

I have a stl::string (and thus, a null terminated C-string) and need to
create a CFStringRef.  There's the CFSTR() macro, bit it only applies to
constant strings, not dynamic run-time strings.  I have the following
code with some questions:

can someone tell me where can I found documentation about writing plug
in for Apple XCode? I've googled around but I have found little information.
Many thanks

I've developed a widget that downloads some text from a website on every
refresh. I need to be able to cache the results to disk and so the only
way to do that seems to be via a cocoa plugin that would save the text
as an XML file to disk and then later retrieve it. I have no ...

    I need to know if there are any low cost alternatives to
REALBasic / CodeWarrior for creating GUI application to run under both
OS X and Windows (other than Java)?
If it's relevant my Mac is a old 867mhz 15in PowerBook running 10.2.8

documentation for the class isn't a good place to start, although I dare

I'm porting a program from Windows to Mac. Most of it's functionality is

times per second it enumerates and saves all windows, founds and saves

I could really use some help here.
I'm going through the projects in "Cocoa Programming for Mac OS X", and
we've gotten to the section on helper objects. In this case, I'm
supposed to drop an NSTableView onto my window, and then set the NSTableView's

When I subclass an object in IB, and then instantiate it, it appears on
the instances tab. From here I can connect outlets, etc. My question
is: how can I access this instance from other parts of my code (i.e.
how do I send it messages?)

Metrowerks recognizes that there is some question regarding the future
of PowerPlant based applications.  Metrowerks will make sure that our
PowerPlant users are able to continue to use the source codes for
PowerPlant and PowerPlantX Frameworks for future development.

I found only the LSheet class.
Thanks,

Today my goal was to load a PNG file into memory, then stamp copies of
the image into my view.  I finally got it to work, but I was left with
a mystery. . .   Why do I have to set the size of the NSimage manually,
using the "setSize:" method?  I assumed "initWithContentsOfFile:" ...

If it finds the text I want to display Message Find.For that I have
written TXNFindPrc But It is not working eventhough word "hello" is

I am just learning Mac programming (coming over from .NET on Windows
Web), and I was going through "Introduction to Developing Coco
Objective-C Applications: A Tutorial". In it, Apple says

I have an HIImageView that I have attached to a scroll view.
Scrolling the image works fine.  But I also have another HIView that
contains Quarts graphics commands that are dependent on user input.
How can I embed this HIView into my HIImageView so it uses the same
