2,880,076 | 2,880,077 | Adding zero to an int variable results in weird number | <p>I'm having a problem with what should be simple additon in Javascript.</p>
<p>Take a look at this firebug output:</p>
<p><img src="http://i.imgur.com/YacT4.png" alt="Firebug output screenie"></p>
<p>What I'm making is a 2D tile map in canvas, and for objects in the map that are greater than one tile in size, they have their width and height set to negative numbers, to tell me how many tiles offset in x/y they are to get to the tile with the relevant data.</p>
<p>This works fine for all cases, except when adding zero to a number. This results in strange numbers.</p>
<p>In the image above, there are two click events fired, each starting with "clicking on X x Y" and ending with "modified x/y into X Y". As you can see, clicking on a tile with a -3 for the Y offset works fine, but clicking on a tile with 0 for the Y offset results in 247!??? I've been going over and over this without getting any closer to an answer. All data seems fine, right up to the point when I try and add 0 to the variable y. If that wasn't weird enough, adding zero to the x variable works fine!</p>
<p>Here's the snippet of code that outputs the debug messages and causes the error. x and y are parameters to a function call, and cityMap is a global 3D array.</p>
<pre><code>if (cityMap[x][y]['typeID']<0)
{
// get deffered tile pos
console.debug("Offset x = "+cityMap[x][y]['width']);
console.debug("Offset y = "+cityMap[x][y]['height']);
x += parseInt(cityMap[x][y]['width'], 10);
y += parseInt(cityMap[x][y]['height'], 10);
console.debug("modified x/y into x:"+x+" y:"+y);

1,753,338 | 1,753,339 | How to use methods from two classes in eachother in Java? | <p>I've been looking around and I only found one answer which wasn't clear enough, to me at least.</p>
<p>I am building a very basic chat application with a GUI and I have separated the GUI from the connection stuff. Now I need to call one method from GUI in server class and vice versa. But I don't quite understand how to do it (even with "this"). Here's what a part of code looks like (this is a class named server_frame):</p>
<pre><code>textField.addActionListener(
new ActionListener() {
public void actionPerformed(ActionEvent arg0) {
try {
srv.sendData(arg0.getActionCommand());
} catch (Exception e) {
e.printStackTrace();
}
textField.setText("");
}
}
);
</code></pre>
<p>This is a code from server_frame, srv is an object from the other class (server) which contains sendData method, and I probably didn't define it correctly so hopefully someone could make a definition of it.</p>
<p>On the other side class server from which object srv was made contains method using JTextArea displayArea from server_frame in this code:</p>
<pre><code>private void displayMessage(final String message){
sf = new server_frame();
SwingUtilities.invokeLater(new Runnable(){
public void run(){
sf.displayArea.append(message);
}
}
);
}
</code></pre>
<p>Yet again sf is an object made of server_frame and yet again probably missdefined :)</p>
<p>Hopefully that was clear enough, sadly I tried the searching but it just didn't give me the results I was looking for, if you need any more info I will gladly add it!</p>
<p>Thanks for reading,</p>

3,986,812 | 3,986,813 | storing ajax result into PHP session | <p>I see examples how to fetch data from php to ajax (and display it via javascript.) As in log-in example, we can check whether there is a valid email and password entered, we can simply display "You are now logged in." Till here I understand and work out. But, now as the user logs in, I need to set the php session.
The login form sends data to the ajax.php, which simply returns a success message. In other case, if I just use php to check valid login details, I can set php session as soon as the script finds match data. </p>
<p>I know I can send ajax data through URL to second php page, where it can access through $_GET. But I want to get that data into SESSION rather than sending through URL. </p>
<p>How I do that?</p>

Used the above code to connect the remote ftp server to do the same job throws exception : Error 550 no file found or no Access.</p>
<p><strong>Question 1</strong> : I have a full permission to read/write for the folder,if its not a permission issue,what else i have to keep it in mind to look for it ?</p>
<p><strong>Question 2</strong>: If i modified my code like
step1: Make"mpg" direcotry first
step2: make"test" directory after that,works fine
is that mean FTP.Makedirectory won't support to create a subdirectory in the main dir ?</p>
<p>If that's the case how it created in my local ftp server ?</p>
<p>Any help appreciated.</p>
