Well, you could write a PHP script that checks that email address and moves any attachments of a given MIME type to a location of your choice, then set up a cron job to run your PHP script every couple minutes. You could also use Dropbox.

How do I set up a script to constantly run? Is that possible? Or even worth it to have a script constantly checking an email box for mail? I don't want to have to do anything other than email the picture when it's done if possible.

You'd write the script to do a single check, then set it to run every minute or half or thirty. If you've Linux or something Unixy you should look up cron, if Windows look up scheduled tasks.

If you've never used cron before, I think you'll be fairly pleased with what it can allow you to do. Check out this guide to get up and running with it pretty quickly.

What am I doing wrong while trying to use SQLite under Eclipse/Ubuntu? I have the dev packages installed and pasted some example code into a new project, but it won't link to the library. It can see the header (the SQLite types work) but the linker thinks all the functions are undefined. Now what?

Did you tell it to actually link the library? -lsqlite3 on the linking commandline, don't know how you'd specify that in Eclipse.

Apparently not. I do know where to put it, just not what the command actually was. Thanks!

alright, I'm taking an object oriented programming class this semester. Our first assignment was to make this really easy java file and run it. I made the file and ran it on the campus PC and it worked fine so I submitted it. Now after trying to run it at home I am getting a couple errors. I'm not sure if I hosed up something when adding system variable or if I indeed hosed up the actual file itself. Anyway here is the code I turned in versus the code given to me in a handout.

turned in:

code:

//HelloPrinter on Notepad and commandline

public class HelloPrinter
{
	public static void main( String [ ] args ) 

		// display a greeting in the console window

	System.out.println("Hello World!");

code given via handout:

code:

public class HelloPrinter
{
	public static void main( String [ ] args )
	{
		// display a greeting in the console window

System.out.println(�Hello, World!�);
}
}

and finally here is the error I get while trying to run the first set of code. all help/feedback is greatly appreciated.

I understand this, which is why I'm a bit confused as to why it isn't working on my desktop. The first set of code worked flawlessly in class, so I turned it in. Now the code does not seem to be working....

If you turned in what you pasted here, it could not have worked.

Edit: To be a little more helpful, the code you say you turned in clearly has a dangling block. Open-curly-braces must be matched by closing-curly-braces.

I see the difference between the two, and changed to code and tried to run it from command line again, now I have 5 errors showing up.

I have no experience in programming, just looking for a little feedback as to what the problem is. Apologies for my stupidity.

You have fancy quotes �� instead of normal quotes "".

# ? Jan 23, 2011 19:35

Internet Janitor: May 17, 2008; "That isn't the appropriate trash receptacle."

There is also a difference between straight quotes (") and curly-quotes (��). If you look at the first error message javac outputs, it's pointing at the first curly-quote in your code. Furthermore, it doesn't look like a quotation mark anymore. This is a clue.

Internet Janitor: May 17, 2008; "That isn't the appropriate trash receptacle."

What's important here is developing some basic debugging skills. The first javac error is the only thing that matters. Look where javac tells you and think about what the error message says. Did you type what you meant? Are []{}() balanced? Etc. When you solve one problem, compile again and see what's next.

What program did you use to create your .java file? If you used a word processor or something, then that's your problem. Seeing that you're on Windows, I guess you should give Notepad++ a try.

Notepad++ loving rocks and if you should use it whenever you don't have a proper IDE. You're in Java though so maybe try Eclipse as well.

I don't care how many people I probably infected with COVID-19 while refusing to wear a mask, my comfort is far more important than the health and safety of everyone around me!

What do you do when you use a library and some programs need version 2.2, some need 2.3, and some old ones need 1.4?

My solution right now is keep all of them on my hard drive and just adjust the makefile of each one so that they aren't using system paths. I guess that's what you have to do but it seems ridiculous to have multiple copies of 500mb source.

I'm back with another question. Not quite sure whats causing errors this time.

code:



/**
	This program tests the Square class.
*/

public class SquareTester
{
    public static void main (String[] args)
    {
        Square standardSquare = new Square();

        System.out.print("The standard square has an area of ");
        System.out.print(standardSquare.getArea());
        System.out.print(" and a perimeter of ");
        System.out.print(standardSquare.getPerimeter());

        System.out.println();

        double side = 13;
        Square mySquare = new Square(side);

        System.out.print("The square with my input has an area of ");
        System.out.print(mySquare.getArea());
        System.out.print(" and a perimeter of ");
        System.out.println(mySquare.getPerimeter());
        System.out.println();

    }

    }

errors are

you need to compile Square.java and put the resulting Square.class in the same directory as SquareTester.java.

Yes. "Symbol" is compiler-lingo for a name that is defined somewhere and is not a reserved word/keyword of the language. The name of a class, a method or a variable is a symbol. (Remember, a symbol talks about the name, not the thing itself. The compiler is telling you, "I have never heard of anything by the name 'Square'.")

Rocko Bonaparte: Mar 12, 2002; Every day is Friday!

I recently got bitten with the embedding scripting language bug and have been wanting to incorporate some kind of interpreter into some stuff I'm working on for work and pleasure. The situations are slightly different, but not by much:

1. C# application into which I want to embed IronPython. It would bring up a Python console such that somebody could live in there and call all my C# stuff if they felt like. I was hoping though that the console could be a GUI control or something similar where I can add some other controls. Are there any up-to-date examples of something like this? I have not done GUI stuff in .NET and I found the text box to be pretty limiting. I don't directly figure out what was added to it, for one thing. If there aren't any good examples of this, does somebody have a good recommendation for some GUI components that would serve well as a shell where the user is typing stuff while something on the other end is spitting back results from the interpeter?

2. C++ application where I'd like to embed Mono and hopefully some shells for whatever language of choice they want to use. I was hoping not to have to implement a shell for each of these, given my fun and games I've seen with #1. I was thinking even of just offering up a socket that would bind to some specific runtime and leave it up to users to implement a shell for it. Or whatever. At the least though I'd personally want to use Python and Ruby with it, so I am trying to find a solution that is sufficient abstract to work with both. Also I am not too hard set on mono, but I want something that will work on Windows and Linux, and has good support for Python and Ruby. Parrot is supposed to do both but I've had nothing but trouble.
