}
}
}
i even tried putting a main method in it but that didnt work,when i used the applet viewer it said the applet was unable to initailise,here is the html code
Code:
<html>
<head><title>LEARNING ON THE WEB</title>
</head>
<body>
<table cellpadding="5" bgcolor="#FF0000">
<tr>
<td>
<APPLET CODE="AppForm2.class" WIDTH="600" HEIGHT="500">
</APPLET></td>
</tr>
</table>
</body>
</html>
and yes they are both in the same directory,please does anybody know to make the applet run,or is there something i'm missing?

Re: My Applet doesnt initialise on the web page
1. Please use code tags when posting code.
2. If your applet throws an exception then post the whole of the exception message and stack trace as that gives a big clue as to what is going wrong.

Re: My Applet doesnt initialise on the web page

If you'd read the "before you post' notes you would know 
The easiest way is to highlight the code and click on the 'code' toolbar button.
The problem with your code is you are trying to use an object that hasn't been created yet, the error is on line 36 (see the exception text). If you look at your code you will see you are setting the frame title but you haven't created the frame object yet - you do that several lines later.

Re: My Applet doesnt initialise on the web page
Thanks,i'll read the "before you post' notes asap,
Whilst my previous post requesting you use code tags was polite, it didn't mean you should only start to use them when you can be bothered to work out how to do it. It mean't use them from now on.
If you are not prepared to make the effort to post your code in a way that makes it easier for us to help you then why should we give up our valuable time to help you.
Also, posting the same monsterous chunk of unformatted code twice won't help you get your post answered either.

Delete everything BUT the first post, then go into that and highlight your code, and press the CODE icon (in the advanced options)

Re: My Applet doesnt initialise on the web page
i have corrected my mistake,the truth is i had no idea of what you were talking about when u reffered to "code tags",i didnt realise they were used just like html tags,i was busy looking for a code tag button somewhere,i even started thinking an administrator disabled it(which would have been odd if true)....
Sorry for the inconvenience. About the applet, i need this first one to send all the details iputed to the database and at the same time make THIS applet disappear and the next one which has a submit button to appear....
the code for the first applet has already been posted this is the second one
Code:
import java.awt.*;
import javax.swing.*;
import java.awt.event.*;
import java.sql.*;
import java.applet.*;
public class AppForm3 extends JApplet
{
JLabel Qualification_Details, Graduation_Degree_Program1, Grade,
School1, University, GRE_Scores, TestDate, Score,Toefl_Score,
Details;
JTextField GraduationField, GradeField,SchoolField1,
UniversityField, GREField, TestDateField, ScoreField,ToeflField;
JTextArea DetailsTA;
JButton Submit;
JPanel pa;
Font fo1=new Font ("Monospaced", Font.BOLD,16);
GridBagLayout gbl;
public void init()
{
pa=new JPanel();
pa.setLayout(new BorderLayout());
gbl=new GridBagLayout();
GridBagConstraints gbc=new GridBagConstraints();
pa.setLayout(gbl);
gbc.gridx = 0;
gbc.gridy = 0;
gbc.gridwidth=2;
Qualification_Details = new JLabel("Qualification Details: ");
Qualification_Details.setFont(fo1);
pa.add(Qualification_Details, gbc);
gbc.gridx = 0;
gbc.gridy = 1;
gbc.gridwidth=1;
Graduation_Degree_Program1=new JLabel("Graduation Degree Program: ");
pa.add(Graduation_Degree_Program1, gbc);
gbc.gridx = 1;
gbc.gridy = 1;
gbc.gridwidth=2;

gbc.gridx =4;
gbc.gridy = 2;

gbc.gridwidth=1;
TestDate=new JLabel("Test Date: ");
pa.add(TestDate, gbc);
gbc.gridx =1;
gbc.gridy = 4;
gbc.gridwidth=1;
TestDateField=new JTextField(10);
pa.add(TestDateField, gbc);
gbc.gridx =2;
gbc.gridy = 4;
gbc.gridwidth=1;
Score=new JLabel("Score: ");
pa.add(Score, gbc);
gbc.gridx =3;

gbc.gridwidth=2;
Details=new JLabel("Details of Recent Honors and Awards: ");
pa.add(Details, gbc);
gbc.gridx = 2;
gbc.gridy = 6;
DetailsTA=new JTextArea(5, 30);
DetailsTA.setLineWrap(true);
DetailsTA.setWrapStyleWord(true);
pa.add(DetailsTA, gbc);
gbc.gridx = 4;
gbc.gridy = 6;
Submit=new JButton("SUBMIT");
pa.add(Submit, gbc);
add(pa);
}
}
But this second applet proved unsuccesful,it didnt load.....i cant understand why
I do hope i have been explicit enough....
.....awaiting your most valued response (ok....now i'm really asskissing lol)

Re: My Applet doesnt initialise on the web page
The point of the CODE tags (explained in the 'Before you post' notes you said you were going to read), is to keep the correct code indentation. There's no point using them if your code isn't correctly indented in the first place. I suggest you indent the code properly.
The applet code you posted should load, if the HTML page to load it is correct.
From a programmer's point of view, the user is a peripheral that types when you issue a read request...

Re: My Applet doesnt initialise on the web page
Took me a while to figure out the code tag thing and believe me i tried to look for the "before u post notes" but couldnt find them.I had to search for code tags,anyway....
.....i dont understand what you mean by my code not being properly indented,please explain
you were right,i think the problem was from my browser.Any way,looking at the codes can u help me figure out how to get my CONTINUE button to show the second applet while hiding the first one. Thank you in anticipation

Then why not ask? The link is clearly visible at the top of the thread list: "Announcement: Before you post"...

Oh good grief... try this.
The outcome of any serious research can only be to make two questions grow where only one grew before...
