You can't nullify an object. If you're using GC, you need to nullify pointers to objects if you are done using them (if they stay in scope) so the GC system knows you're done using them and they can be reaped. As long as your NSMutableArray is in scope, it will have a reference to your object, so your object will not be reaped. -Lee

Not a "better genstrings", but maybe a better production pathway: http://wilshipley.com/blog/2009/10/p...7-lost-in.html

Yeh your totally right about them rushing us through courses... exactly what you said also about giving you pre-written code and copy and pasting it.. its really not a great way to learn! ... our php classes are even worse! They should really teach us a basic language like pascal.. but then again no-one would even sign up for the classes if they did... Cheers anyway guys... im gonna try advance on my own some more.. counting loops seem to be...

The "proper" menu items run in SystemUIServer rather than in the applications that provide them, which is a bit of a risky thing to do. Some sort of in-between solution (perhaps something like how DockTile plugins work) seems appropriate. Have you filed a request with Apple for this at bugreport.apple.com?

I try it on my computer since I couldn't find the problem visually.
There's no problem it work, make sure you have the permission to create those file inside the folder where you run your program. You can verify the file openned correctly:
if(! euler.is_open())
{
std::cout << "File cannot be created" << std::endl;
}
Here's a few thing, you have a int main() that return ...

First, if you own a file or folder, then you always have the ability to change its permissions. No authentication dialog is needed.
Second, changing the permissions to 0777 (octal) does not prohibit access by others. Quite the opposite: it grants read and write access to everyone. Anyone can read or write to the file. It also marks the file as executable, which is simply wrong for a...

I don't know about what you're doing (over my head ). The simplest way I can think of to load and convert images is through SDL/SDL_image. Load the image using Load_IMG() into an SDL surface, then convert it to the format you want. There are tutorials around the interwebs for converting an SDL_surface into something OpenGL can read, for instance.

Just make it OpenGL, so it'll be cross-platform.

Not sure how precise this needs to be. i'd do this with regular expressions using Pattern:
http://java.sun.com/j2se/1.4.2/docs/...x/Pattern.h tml
If you don't want to/can't go that route, you can add after this line:
Code:
String [] splitupText = line.split(":");
A check to see what the length of splitupText is. if it's not exactly 4, failure. If it is, the first two ...

If you can post the debugger where they crash that would help.
3.2 by default links against the 10.6 SDK which may do things a little differently (I just noticed this yesterday with a project I opened for the first time that crashed on SL but not on Leopard).

You're not just printing the bytes of the string in reverse order; you're printing the bytes of the entire 700-byte buffer in reverse order.
I see that you've tried to compensate for this by trying to print only characters with certain ASCII values. However, when your program starts, your 700-byte buffer might not be all zeros; it'll probably be filled with random values, some of which ...

The first thing that comes to mind is to exec the authopen command.
http://developer.apple.com/mac/libra...uthopen.1.h tml
I recommend you try it first in a Terminal shell window.
Also, be sure to use the String[] form of exec(), not the single-String form.

If you've got Xcode installed then 'curl.h' is already available as expected. Not need to install anything else.
Now if you go ahead and install a newer version of 'curl' someplace on the system other than over the existing version (which I don't recommend myself) you'll need to do some extra work to point to the newer headers.

I don't know RB, but it sounds like you want to use an index value.
If the Popup has the option of returning a numeric value (or deriving it somehow) for the position selected, then that can be used to use gain access to the second array. Assuming your array positions start at zero, it might be 1 in RB, here is what you want. If RB uses 1, I'll leave it to you to figure out the math.
