View Replies View RelatedI want to do an app that capture a selected area of a screen and save it. I did a few research and i did the code down below.

I have a combobox with this PopupMenuListener. All works fine, except that the popupMenuWillBecomeInvisible method does not capture the selection made and neither does it show the selection.
PopupMenuListener pmlMqMessagePurged = new PopupMenuListener() {
@SuppressWarnings("unchecked")
public void popupMenuWillBecomeVisible(PopupMenuEvent arg0) {
try {
JdbcSqlServerDataSource ds = new JdbcSqlServerDataSource(
DbConnectionURL.UToolDbHostName, 0,

The popupMenuWillBecomeInvisible does fire but the System.out.println() returns 'nul'l as answer to the value i have selected from the combobox.
For one of my project, required to capture the audit history reports of all the activities of the users within the application.
We are using Servlet/JSP in J2EE environment.

Just want to know the best way to do this..any frameworks available for it...or doing at the database side like using triggers..

I successfully added a background image on the Panel but I can't create my JButton image on top of my background image.
ImageIcon piano = new ImageIcon("src/img/piano_backgrd.png");
JLabel backlabel = new JLabel(piano);
panel.add(backlabel, new Integer(Integer.MIN_VALUE));
backlabel.setBounds(0, 0, piano.getIconWidth(), piano.getIconHeight());
JButton volup = new JButton(new ImageIcon("src/img/volup.png"));
volup.setLocation(10, 0);
panel.add(volup);
I'm trying to make a method that takes an image and turns it into a tile image. So if the original image looks like this:
[URL] ....
then the output image should look like this:
[URL] ....
Here's a method that's supposed to do that but for some reason the output image looks the same as the original:
public static int[][] tile(int[][] arr){
int[][] tile = new int[arr.length][arr[0].length];
for (int i = 0; i < arr.length; i++) {
tile[i]=arr[i];
}
return tile;
}
I recently changed the method and the error message I'm getting is "bad operand types for binary operator '+'. Here's the method:
public static int[][] tile(int[][] arr){
int[][] tile = new int[arr.length][arr[0].length];
for (int i = 0; i < arr.length; i++) {
for(int j=0; j<arr[i].length;j++){
tile[j]=(tile[j])+(arr[i]);
}
}
return tile;
}
how to hide an image in another image in java
By using Steganography we can hide text in an image. But how it works for image.
I'm trying to add an image icon to my application but since the code will be checked by another computer, I cannot use an image in my computer and use its file address. If I save the image in the project, is there a way to get the file address of the source code? Or is there a better way to add a unique image icon to the app?

How can I find the DPI of an image? The following code tells me the size of the image in pixels which I want to convert to millimetres. When I have looked at conversions I can find - "mm = (pixels * 25.4) / dpi" but how do I find out the DPI?

View Replies View RelatedI'm trying to flip an image horizontally. However because when I flip the images they're offset by a bit, I added "-height" to offset the change in position. Unfortunately, it doesn't seem to be working 100% of the time; some images are adjusted to their correct position but some are not.I'm using this line to flip an image: Java Code: g.drawImage(castle, x, y - height, -width, height, null); mh_sh_highlight_all('java');
