Ok so I have a couple questions on JavaFX. I have three javaFX scripts all of which contain their own scene and stage. However, I want a main class or script to decide when to open and when to close...

Very nice. Can I ask, what language did you use for the conferencing. Was it java, if so how did you achieve it, because I want to do desktop video chat.

Ok so what does mysql return when the select query doesnt exist. So say I query the database: SELECT username FROM user WHERE username='test' AND password='test'

Ok so say test doesnt exist what...

ok thanks, but were would i find the driver class?

Ok so what i want to be able to do is connect to a mysql database. Here's my code so far:


Connection connection = null;

String driverName =...

Ok so im thinking of building a chat application like msn in java. Would JMF be the best option or has anyone got any other ideas. Also are there any tutorials or open source code at there that...

Thank you for the help, I will try your code, but as i said, the only problem is that the icellselcted always returns false.

what are you talking about? You are not being particularly helpful. Sorry to say this, but that post had nothing to do with what your asking, nor are you trying to answer it. My question is why is it...

what?
I can post all the code but i think its unnecessary. The problem is not with the code but with that method, provided by JTable.

thats pretty much exactly what i have done, however, the cell never gets the value assigned to it. This is because for some reason the isCellSelected() method always returns false.
Thats what I dont...

Ok thanks but I have already set cell selection to true, so i dont know why its not working.

ahh thanks. I didnt see that!
But now it never prints works again so i dont think it registers if a cell has been selected.

Any ideas as to why?

Ok so im building a level editor for this game. What the code i cant working does is, when the button is clicked it should get the selected cell from the jtable and set a value for it. However, for...

I know we are not supposed to ask for code, but could someone please tell me how I would do this. Not write code, just give me guidelines.

int[][][] testArray = new int[10][5][5];

That is the syntax for a 3 dimension array of ints.

window.setAlwaysOnTop(boolean);
window is the name of your jframe and replace boolean with true or false depending if you want the visible to be on top.

Also do what msn does, play a sound.

use opencv

ezza is right, it would be better if you code it yourself. How about you try and then you show us what you have done, if it does not work then tell me and ill actually do it for you. But its better...

how about a network messaging app?

ok, ill see if i can do it now, if not it will be done by tomorrow :)

you would create an arraylist because, you dont know how long the names would be to start of with. Plus with arraylists you can easily convert char's because all you want to do is convert two. Then...

why dont you just change the format of the users input. Instead of making the value of there input a string make it a double

use getters and setters

OK, i didnt really look at your code to much, but this is what you need to do. You need to break the string up into char's using this method: getChars(). Store this in an array list. You should then...

hey, ok vernon provided you with an almost complete answer. I dont know if you understand yet that methods that are private cannot be accessed outside the class. It is also bad programing to make...

I do have a couple of years! Obviously id make it with someone else. But what i want to know is that is there already a kernel written and boot-loaders etc. Because if there is then it wont be to...
