How to remove events not used in NETBEANS

You might want to remove some events that are not used anymore in your NetBeans file project. You cannot just delete it from the code editor because NetBeans lock it, indicated by the gray color of the line of codes.
Here's how to remove those unused codes:

1. Go to the GUI builder, the Design view of your file.
2. Right click and select Properties. The default open tab is the Properties list. Select the Events tab.

3. You would see events list and what handlers these events are associated.

4. Choose the event you'd like to delete by selecting the [...] button.

5. A new dialog will pop up. Select the handler then click Remove button.

How to change any date format to DATE datatype in MySQL (Insert or Update)

 ----

Use this function:  STR_TO_DATE('date', 'format')

This accepts two parameters: date and format where date is the input raw date you want to change and format is the corresponding format relative to date that you want to change.

For example:
INSERT INTO table(date_field) VALUES(STR_TO_DATE('December 8, 2010','%M %d,%Y'));

Note: table is the name of the table in database and date_field is the name of field in DATE datatype.

The statement above shows 2 parameters date as 'December 8, 2010' and format '%M %d, %Y'. The format is the exact format of the date, so that the mysql knows from what format will it convert the date  to DATE datatype format which is '%y-%m-%d'.

Other valid examples are:

INSERT INTO table(date_field) VALUES(STR_TO_DATE('12-31-2004', '%m-%d-%Y'));

INSERT INTO table(date_field) VALUES(STR_TO_DATE('12/31/2004', '%m/%d/%Y'));

UPDATE table SET date_field =  STR_TO_DATE('Dec 31, 2004', '%b %d, %Y');

How to disable edit cell in JTable (especially in NetBeans)

Put this in your code:

table = new javax.swing.JTable(){

    public boolean isCellEditable(int rowIndex, int colIndex) {

        return false;   //Disallow the editing of any cell

    }

};

where table is the name of your JTable.

For NetBeans users:
1. select the table GUI, right click, select Customize Code
2. Your code should look like this:

How to Select All textfield/ password field Java

--start--
Sample code:

     int i = textfield.getText().length();
     textfield.setSelectionStart(0);
     textfield.setSelectionEnd(i);


Put this in the action or wherever you want it. Replace textfield variable to the name of your textfield. I'm not sure but this might work for JTextArea and JTextPane too.

How to redirect Back to previous page PHP

Put this in your code:

that is a javascript code.


As for me, I embedded it to my php file like this:

if(!checkEverything()){ // a function that contains checking of fields.

SCRIPT HERE* //redirects Back to the previous page with values still in the form

    }else{

    displayAll(); // a function that displays all

}

Note: I cannot add the script as it is because blogspot reads the script and the effect is redirecting you to your previous page. As an alternative I put it as image :)

Hope this helps. It worked 100% for me :)

How to remove JTextArea line around rectangle (border)

 code:

textarea.setBorder(null);

In NetBeans:
1. Click the text area
2. Go to Properties
3. Scroll to Other Properties
4. Go to border then select (No Border)

5. Put this in your constructor:

jScrollPane1.setBorder(null);

This is because NetBeans automatically creates scrollpane to your text area and its border is visible until you set it to null.

6. Run the file to see the result.

It worked for me just fine :)

How to resize ImageIcon - Java

Please make reading a habit :)

 This was my problem before. After  days of searching, I combined the codes of my search items and came up with this:

-- start of function. I put it inside a function --

//gets the directory of the file

//this means that the file name is where the directory is plus the folder pictures plus the filename

//which is hold by the string named idnumber

idnumber = "CO00001";

dir_pic = System.getProperty("user.dir"); 

dir_pic = dir_pic+"\\Pictures\\"+idnumber+".jpg";

//you could simply put the path of the image in dir_pic variable

//We should have an image first.

//For me, I open the image from my directory

File file = new File(dir_pic); 

image = ImageIO.read(file); //reads the image

//this sets the image to an Image Icon
ImageIcon icon = new ImageIcon(image);

//we start to scale here

//first get the image from ImageIcon
Image img = icon.getImage();

//then scale it; I scaled it to 120x120

//please check the documentation for parameter listing if u dont want SCALE_SMOOTH

Image newimg = img.getScaledInstance(120, 120,java.awt.Image.SCALE_SMOOTH); 

newIcon = new ImageIcon(newimg); //we now have new icon - scaled by 120x120

//I made a JLabel named label and put the image there

label = new JLabel(new ImageIcon(newimg)); 

//then put the label to a square panel

picpanel.add(label); 

label.setBounds(2, 2, 115, 105); //change the bounds according to your design

--- end of function ---

..And guess what, I have these all.. zzz...

Joomla! BUGS! ERRORS!

It's so hard to install Joomla! I get so many errorsssss! It's pissing me off! At first I had "Error 1045" in my installation. Then I edited the sql code, changed all "TYPE = MyISAM" to ENGINE = MyISAM. After that I was able to install but when I went to the administrator area all I see is a blank page!

If it's this hard to user this CMS, someone kill Joomla community please!!!!

UPDATE:

I already know the bug. Joomla's database server has a conflict to my installed MySQL server. I now appreciate Joomla after really getting to know it. But the installation is really hard.

XAMPP phpMyAdmin Error 1045 Access denied for user

Description of error: This appears when you click the phpMyAdmin link from xampp home page. The error looks like this:

The using password: NO means that xampp configuration has no password to database server stored in it. The error could also be: Access denied for user 'root'@'localhost' (using password: YES). This error means xampp has a password for the database server but it is incorrect.

Solution:

1. Go to C:\xampp\phpmyadmin then open the config.inc or config.inc.php file


2. In line 20 you will see this: $cfg['Servers'][$i]['user'] = 'root';
Make sure that the 'root' there is the user to access your own database server. If not, change the 'root' to your own user name.



3. In line 21 you will see this: $cfg['Servers'][$i]['password'] = '';
This means that your database server doesn't have password save in it. If your database server has a password, type the password between the single quotes for example 'mysql'.

However, if there is a password stored like this: $cfg['Servers'][$i]['password'] = 'mysql'; then you have to change 'mysql' into the password your database server is using for example 'developer_password'

4. Clear your cookies then reload localhost


Hope this helps, I tried it and it worked.

My case of: Jasper Report won't run

___________________________________________________________

We have a system that would print student profile, on our implementation we used the jar file to execute the system for our demo. Then we found out that one function is not working.

Case: when I clicked the JButton that triggers Jasper reporting, the preview of the document wont show up. It appears in other computers but some other pc units wont, too.

After how many trials, debugging and troubleshooting, we decided to install the IDE in the deployment PC. Then we saw the bug, at last.

Bug: No FONT installed. We used a font in the development environment where that font is not installed in the PC of the deployment environment. So that what kept our project delayed for a week. lol.

My TOP 2 Netbeans IDE 6.7.1 Annoyance

1. When I type JOptionPane then hit the period "." key the available attributes should appear but as I type JOptionPane.showConfirmDialog and put 4 parameters, the last parameter won't auto complete anymore. I am supposed to put JOptionPane.YES_NO_OPTION, now I have to type every letter of it. So annoying for me.

2. The codes won't 'refresh' right away. Sometimes I have to run my program 3 times for my changes in the code to take effect. Soooo annoying.
