Oops, forgot a follow-up.
Alternatively, if the scripts you want to run are Perl, you can use require:
.. random code ..
if ( .. some condition .. )

You can use the backticks (`) to execute a system command:
$result = `random system command`;
This will execute "random system command" and then put the output of the command into $result.

If you're using onchange, Firefox doesn't trigger the event until the focus leaves the field. You should use onkeyup instead if you want the event to fire whenever the user types something.

Which X library are you using? GTK+, qt, wxWidgets? There isn't a single API.

I usually use ImageMagick, but I think DevIL (formerly OpenIL) might be pretty good: http://openil.sourceforge.net/
Not sure how performance oriented it is, but you can use it in conjunction with...

In unistd.h there is a function called getcwd() that gets the current working directory.
You can use getenv (in stdlib.h) to get the HOME environment variable, which is by default /home/username/:...

Looks to me like your algorithm is to find a single path. You set the nodes to visited, then once you've found a path it returns and doesn't look for any more paths.
What you should be doing...
Since your masks are all zero, it filters out any colours you're trying to put. Hence why you have black ;)
Try putting this in:
Uint32 rmask, gmask, bmask, amask;
rmask = 0x000000ff;
If you're new to Linux, or don't feel like spending hours learning how to use the text editor, don't go with vi/vim or emacs. These editors are very powerful, but take a long time to learn.
Then I'd recommend going with C and some library, be it DirectX, OpenGL, SDL, or whatever. They probably either used one of those, bought a commercial library to use, or rolled their own. I doubt...

I think you're going about this the wrong way. There are usually several ways to solve a given problem. By wasting a lot of time trying to figure out how somebody else did it, why not just do it your...

Please use code tags, like this:
This is a block of text surrounded by [code] tags.
inFile.seekg(ios_base::beg); after your first inFile.close().

You can use OpenGL too. Or, try downloading the source for Gecko and take a peek at that.

What 7stud is trying to say is "use code tags", like this:
here is some code, I used a [code] tag for it

You can use a recursive parser, like this (pseudo-code):
function parse(input, i)
if input[i] = ']' return null
node = new node
node.value = parse an (x,y)
accept a '['

I'd stick to OpenGL for the following reasons:
1) It's cross-platform. This might not affect you now if you don't use a non-Windows platform, but in the future you might want to have a version for...

When using a command line like this:
a.out < file1
it loads the file in using cin (only on Linux too, this won't work on Windows), but like this:
a.out file1 file2

Use the ps command with the a modifier to get a list of your processes, and pipe it to grep:
ps a | grep perl
From this you should see something like:
6343 pts/0 Ss+ 0:00...

No problem. You'll also find the Prototype library that Scriptaculous is based on very useful when you start learning AJAX. I would recommend looking at this too.

You can do something like this:

There's a couple ways of doing this. First, are you using #ifndef/#defines at the start of your .h file? Like this:
//stuff in the file

If you're using a FILE pointer, you can do the same technique RandomPerson said, except with the C file functions:
FILE * myFile = fopen("...", "r");

You could inherit a class from ios_base or ios, however you'll have to manually override the << operator for each type you want to be able to use.
If you want you could probably just write your...

OpenGL is a library for using 3D graphics. It is cross-platform and relatively simple, at least compared to Direct3D. I don't think I really need to go into details on the usefulness of 3D graphics,...
