JScrollPane jsp;
public smileys()
{
setSize(250,200);
setTitle("Insert Smiley");
setDefaultCloseOperation(EXIT_ON_CLOSE);
Container c=getContentPane();
for(int x=1;x<54;x++)
{
if(x==3 || x==5 || x==22 || x==27 || x==30 || x==32 || x==33 || x==42 || x==44 || x==48 || x==50 || x==51)
{
continue;
}
else
{
img=new ImageIcon("c:/smilieys/" + x +".gif");
System.out.println("c:/smilieys/" + x +".gif");
ms.add(img);
}
}
jl=new JList(ms);
jl.updateUI();
jsp=new JScrollPane(jl);
c.add(jsp);
setVisible(true);

Hi
Here are the things I normally do when loading Images.
1) Make sure your file names are the same case. Some image editors saves the extensions of files to uppercase.
2) Make sure that your images is in the classpath.
3) Use the following to load images
img = new ImageIcon(smileys.class.getClassLoader().getResource("c:/smilieys/" + x + ".gif")).getImage()
I always use the Class Loader, that way you sure that it will search the correct paths for your images. This also works when you create jar files and include your images. Even with applets !!!!!! Trust me I'v spend months on getting to load images correctly. And as always the solution is a simple 'One Liner' :-)

if(x==3 || x==5 || x==22 || x==27 || x==30 || x==32 || x==33 || x==42 || x==44 || x==48 || x==50 || x==51)
{
continue;
}
else
{
img=new ImageIcon("c:/smilieys/" + x + ".gif");
System.out.println("c:/smilieys/" + x + ".gif");
ms.add(img);
}
}
WTF... If I ever saw that sort of code in an application I'd sit the author down for a chat :o)
And, as above, use the classloader. Though note that the code suggested won't work - you'll need to change your path string to a relative classpath value rather than an absolute filesystem value. Eg,
img = new ImageIcon(getClass().getResource("images/" + x + ".gif"));

That's only because you don't know enough about numerology :-P

5 - the first safe prime number

30 - the first sphenic number
32 - the number of variations in Bach's Goldberg variations
33 - the smallest integer such that it and the next two integers all have the same number of divisors
42 - really, do I need to explain this one?
