Help with hp b t 500
I have a dell d620 laptop , OS vista business 32bit, hp photosmart 7360, and just purchased the hp bt 500 blue tooth adapter for my printer.
The problem I am having is the BT 500 shows up on my blue tooth devices in vista. In device manager I have exclimation points for 3 bluetooth peripheral devices shown in Other devices.It also states no drivers are installed for these devices. Every time I boot up my laptop it ask me to install the drivers for new hardware which are these items. I try to install the drives from the disk and from the hp web site and when istalling get message no blue tooth devices found stop installation.
Also if I open up a word document and tell it to print my printer shows up but never prints. I open up the print folder and it shows that it was sent but I have a print error. Has anyone had these issues with this blue tooth device and what was done to correct the problem?
weird I have the same monitor and mine works fine. Do you have a different display to check and see if maybe it is your dvi port?

Please help with SSL POST: Servlet returns Error 500
I am struggling for many days to get a Java program to log in to an SSL page. The program is supposed to track ADSL usage statistics from https://secure.telkomsa.net/titracker/, but I never seem to get around Server returned Error 500.
Could anyone please help me understand what I am doing wrong by looking at the method I used. (It seems on the server side it is a jsp servlet that handles authentication).
Any help is deeply appreciated!
I copy-paste the method directly from NetBeans:

//set, add it as a new provide to the Security class.
final Class clsFactory = Class.forName("com.sun.net.ssl.internal.ssl.Provider");
if( (null != clsFactory) && (null == Security.getProvider("SunJSSE")) )
Security.addProvider((Provider)clsFactory.newInstance());
} catch( ClassNotFoundException cfe ) {

Search help with new selection within if more than 500 entries
Dear all,
I created a new search help and this works fine ... If I compare my search help with a default search help from SAP, I have 1 small feature that not seems to work ... With the default one, it is possible to make a new selection within the search help by clicking on the arrow down :
If I look at my search help, I don't have the possibility to make a new selection :
Does anyone how this can be done ?
Thanks in advance !
Greetz,
Kurt.HI,
Here are the general steps to get you started.
1. Identify the search help being used (on the ship-to-party field, F1 then Tech Info). I believe you want the collective search help SD_DEBI.
2. Create your own search help with the fields you want to use with SE11, like 'ZDEBI' as an example.
3. Append 'ZDEBI' to SD_DEBI. (Goto->Append Search Help).
4. Clean things up by "Hiding" the old search help. In the 'Included Search Help' tab of the collective search help SD_DEBI, there is a check box that you can tick to hide included search helps. -

Please help with my incessant spinning wheel of death!
I have almost always had the spinning circle of death… Almost the whole life of this late 2011 15" 4 GB mbp. I just can not easily use this computer anymore. It takes so long to do anything. I need to exit all apps but the one I am using to make it work. I have to restart is almost daily to make it do much. So frustrating! Please help!
I already tried a disk repair under disk utlility with no issues shown.
I read on another post to run an etrecheck app and to post that info. Here is what it says.

Need help with Itunes Authorization issue
I've been a Itunes/Ipod user for a couple years. During that time, I've sure spent over $500.00 on Itunes music from the Itunes store for my Ipod. My daugter and I both have Ipods.. There have only been 2 machines with Itunes installed here but I occasionally rebuild my computers to have the latest and greatest hardware for my business.. The other day I backed up all my music and data before rebuilding my machine due to hardware upgrades. Everything went smoothly including importing my purchased music back into Itunes.. The problem is I can't listen to it now. When I try to double click a song I get an error that says "You have already authorized 5 computers with this account. To authorize this computer you must first deauthorize one of the other computers" This isn't possible because the computers aren't around anymore to deauthorize. They were all housed (except 1, my daughters pc) in the same case as I have now.. Please respond...
The other day I backed up all my music and data before rebuilding my machine due to hardware upgrades.
okay. you may have ended up with multiple authorisations on that PC due to the system changes. if so the following documents should be of some help with techniques for freeing up authorisations:

Need Help With File Matching Records
I need help with my file matching program.
Here is how it suppose to work: FileMatch class should contain methods to read oldmast.txt and trans.txt. When a match occurs (i.e., records with the same account number appear in both the master file and the transaction file), add the dollar amount in the transaction record to the current balance in the master record, and write the "newmast.txt" record. (Assume that purchases are indicated by positive amounts in the transaction file and payments by negative amounts.)
When there is a master record for a particular account, but no corresponding transaction record, merely write the master record to "newmast.txt". When there is a transaction record, but no corresponding master record, print to a log file the message "Unmatched transaction record for account number ..." (fill in the account number from the transaction record). The log file should be a text file named "log.txt".
Here is my following program code:

I am not sure what is wrong with my code above to make my results different from the correct results.
Much help is appreciated. Please help.From the output, it looks like one problem is just formatting -- apparently you're including a newline in log entries and not using tabs for the newmast output file.
As to why the numbers are off -- just from glancing over it, it appears that the problem is when you add multiple transaction values. Since account.combine() is so simple, I suspect that you're either adding creating transaction objects incorrectly or not creating them when you should be.
Create test input data that isolates a single case of this (e.g., just the Mary Smith case), and then running your program in a debugger or adding debugging code to the add/combine method, so you can see what's happening in detail.
Also I'd recommend reconsidering your design. It's a red flag if a class has a name with "Create" in it. Classes represent bundles of independant state and transformations on that state, not things to do. -
Errors driving me crazy! although compiles fine
I am working on a project for an online class - I am teaching myself really! My last assignment I cannot get to work. I had a friend who "knows" what he is doing help me. Well that didn't work out too well, my class is a beginner and he put stuff in that I never used yet. I am using Jgrasp and Eclipse. I really am trying but, there really is no teacher with this online class. I can't get questions answered in time and stuff goes past due. I am getting this error:

The assignment is:
Create a Java program to read in an unknown number of lines from a data file. You will need to create the data file. The contents of the file can be found at the bottom of this document. This file contains a football team's name, the number of games they have won, and the number of games they have lost.
Your program should accomplish the following tasks:
1. Process all data until it reaches the end-of-file. Calculate the win percentage for each team.
2. Output to a file ("top.txt") a listing of all teams with a win percentage greater than .500. This file should contain the team name and the win percentage.
3. Output to a file ("bottom.txt") a listing of all teams with a win percentage of .500 or lower. This file should contain the team name and the win percentage.
4. Count and print to the screen the number of teams with a record greater then .500 and the number of teams with a record of .500 and below, each appropriately labeled.
5. Output in a message box: the team with the highest win percentage and the team with the lowest win percentage, each appropriately labeled. If there is a tie for the highest win percentage or a tie for the lowest win percentage, you must output all of the teams.

Hello. I am somewhat new to Java and I was recently assigned to do a simple paint program. I have had no trouble up until my class started getting into the graphical functions of Java. I need help with my program. I am supposed to start off with a program that draws lines and changes a minimum of 5 colors. I have the line function done but my color change boxes do not work and I am able to draw inside the box that is supposed to be reserved for color buttons. Here is my code so far:

New to Mac, Help with Time Machine! Partition External HDD or not?
Hey Guys I'm a new mac user
I need help with time machine
I wanted to know how time machine works and what all does it back up?
I have 2 hard drives one is of 1TB and one is of 320gb
In the 1TB hard drive i store all my music videos and work stuff it is windows formatted
The 320gb hard drive is mac formatted and I was thinking of making a partition on it one with 250gb for time machine and the remaining 70 gb for mac softwares and files. The ssd of my mac has a capacity of 256gb. I have read for time machine you need at least 2x the space of your ssd on your external hard drive but i don't understand if my ssd is only 256 and can store files worth 256gb why do i need double the space? Secondly if I choose to use the complete 320 gb for time machine will that be okay or even if i choose to partition it to 250gb for time machine will that be fine too? Or will I need to format my 1TB hard disk out of which currently only 300 gb is empty and partition that to 500 gb for time machine?
I'm really confused every tells me to use time machine but do I need it? And what does it exactly do?
Your input will be really appreciate thanksThe reason that you want a partition (or drive) of 2-3 times the size of your boot drive for Time Machine is so that you can keep backups further back than just the current boot drive state - for that you'd need to make a clone of the drive rather than using Time Machine (see -> http://pondini.org/TM/Clones.html).
For more information for backups in general, see -> Most commonly used backup methods.
Note that you can't use Time Machine to backup a Windows partition.
Good luck,
Clinton

Hi, I'm not sure if I'm allowed to post questions on this forum but I can't find anywhere to talk to helpful people about programming.
I'm making a dnd interface for JComponents. So far I've made a simple program that has a Component that can be lifted from a container and braught to the glass pane then later moved to anywhere on the screen and dropped into the container below it. Here's where my problems come:
1) Rite now my 'Movable Component' is a JPanel which is just colored in. I want to either take a Graphic2d from a JComponent/Component and draw it on the JPanel or change the JPanel to the component I want to paint and disable the component.
The problem with getting the Graphics2d is that if the component isn't on the screen it doesn't make a graphic object. I tried messing with the ui delicate and overriding parental methods for paintComponent, repaint, and that repaintChildren(forget name) but I haven't had luck getting a good graphics object. I was thinking of, at the beginning of running the program, putting 1 of each component onto the screen for a second then removing it but I'd rather not. I'd also like to change the graphics dynamicly if someone stretches the component there dropping and what not.
The problem with disabling is that it changes some of the visual features of Components. I want to be able to update the Component myself to change how it looks and I don't want disabling to gray out components.
I mainly just dont want the components to do any of there normal fuctions. This is for a page builder, by the way.
Another problem I'm having is that mouseMotionListener is allowing me to select 2 components that are on top of one another when there edges are near each other. I don't know if theres a fix to this other than changing the Java Class.
My next problem is a drop layout manager, but I'm doing pretty good with that rite now. It'll problem just move components out of the way of the falling component.
One last thing I need help with is that I don't want the object that's being carried to go across the menu bar and certain areas. When I'm having the object being carried I have it braught up to the glass pane which allows it to move anywhere. Does anyone have any idea how I could prevent the component from being over the menu bars and other objects? I might have to make 1 panel is the movable area that can then be broken down into the 'component bank', 'building page' and whatever else I'm gonna need.
This is all just test code to get together for when I make the real program but I need to make sure it'll be possible without a lot of hacking of code.
Sorry for the length. Thanks for any help you can give.The trick to making viewable components that have no behaviour, is to render them onto an image of some sort (eg a BufferedImage). You can then display the Image on a JLabel that can be dragged around the desktop.
Here is a piece of code that does the component rendering for you. This particular example uses a fixed component size, but you can modify that as you choose of course...public class JComponentImage
private static GraphicsConfiguration gConfig;
private static Dimension compSize = new Dimension(80, 22);
private static Image image = null;
public static Image getImage(Class objectClass)
if (gConfig == null)
GraphicsEnvironment gEnv = GraphicsEnvironment.getLocalGraphicsEnvironment();
GraphicsDevice gDevice = gEnv.getDefaultScreenDevice();
gConfig = gDevice.getDefaultConfiguration();
image = gConfig.createCompatibleImage(compSize.width, compSize.height);
JComponent jc = (JComponent) ObjectFactory.instantiate(objectClass);
jc.setSize(compSize);
Graphics g = image.getGraphics();
g.setColor(Color.LIGHT_GRAY);
g.fillRect(0, 0, compSize.width, compSize.height);
g.setColor(Color.BLACK);
jc.paint(g);
return image;
}And here is the class that makes the dragable JLabel using the class above...public class Dragable extends JLabel
private static DragSource dragSource = DragSource.getDefaultDragSource();
private static DragGestureListener dgl = new DragMoveGestureListener();
private static TransferHandler th = new ObjectTransferHandler();
private Class compClass;
private Image image;
Dragable(Class compClass)
this.compClass = compClass;
image = JComponentImage.getImage(compClass);
setIcon(new ImageIcon(image));
setTransferHandler(th);
dragSource.createDefaultDragGestureRecognizer(this,
DnDConstants.ACTION_COPY,
dgl);
public Class getCompClass()
return compClass;
}Oh and here is ObjectFactory which simply instantiates Objects of a given class and sets their text to their classname (very crudely)...public class ObjectFactory
public static Object instantiate(Class objectClass)
Object o = null;
try
o = objectClass.newInstance();
catch (Exception e)
System.out.println("ObjectFactory#instantiate: " + e);
String name = objectClass.getName();
int lastDot = name.lastIndexOf('.');
name = name.substring(lastDot + 1);
if (o instanceof JLabel)
((JLabel)o).setText(name);
if (o instanceof JButton)
((JButton)o).setText(name);
if (o instanceof JTextComponent)
((JTextComponent)o).setText(name);
return o;
}Two more classes required by this codepublic class ObjectTransferHandler extends TransferHandler {
private static DataFlavor df;
* Constructor for ObjectTransferHandler.
public ObjectTransferHandler() {
super();
try {
df = new DataFlavor(DataFlavor.javaJVMLocalObjectMimeType);
} catch (ClassNotFoundException e) {
Debug.trace(e.toString());
public Transferable createTransferable(JComponent jC) {
Transferable t = null;
try {
t = new ObjectTransferable(((Dragable) jC).getCompClass());
} catch (Exception e) {
Debug.trace(e.toString());
return t;
public int getSourceActions(JComponent c) {
return DnDConstants.ACTION_MOVE;
public boolean canImport(JComponent comp, DataFlavor[] flavors) {
if (!(comp instanceof Dragable) && flavors[0].equals(df))
return true;
return false;
public boolean importData(JComponent comp, Transferable t) {
JComponent c = null;
try {
c = (JComponent) t.getTransferData(df);
} catch (Exception e) {
Debug.trace(e.toString());
comp.add(c);
comp.validate();
return true;
public class ObjectTransferable implements Transferable {
private static DataFlavor df = null;
private Class objectClass;
ObjectTransferable(Class objectClass) {
try {
df = new DataFlavor(DataFlavor.javaJVMLocalObjectMimeType);
} catch (ClassNotFoundException e) {
System.out.println("ObjectTransferable: " + e);
this.objectClass = objectClass;
* @see java.awt.datatransfer.Transferable#getTransferDataFlavors()
public DataFlavor[] getTransferDataFlavors() {
return new DataFlavor[] { df };
* @see java.awt.datatransfer.Transferable#isDataFlavorSupported(DataFlavor)
public boolean isDataFlavorSupported(DataFlavor testDF) {
return testDF.equals(df);
* @see java.awt.datatransfer.Transferable#getTransferData(DataFlavor)
public Object getTransferData(DataFlavor arg0)
throws UnsupportedFlavorException, IOException {
return ObjectFactory.instantiate(objectClass);
}And of course the test class:public class DragAndDropTest extends JFrame
JPanel leftPanel = new JPanel();
JPanel rightPanel = new JPanel();
Container contentPane = getContentPane();
Dragable dragableJLabel;
Dragable dragableJButton;
Dragable dragableJTextField;
Dragable dragableJTextArea;
* Constructor DragAndDropTest.
* @param title
public DragAndDropTest(String title)
super(title);
dragableJLabel = new Dragable(JLabel.class);
dragableJButton = new Dragable(JButton.class);
dragableJTextField = new Dragable(JTextField.class);
dragableJTextArea = new Dragable(JTextArea.class);
leftPanel.setBorder(new EtchedBorder());
BoxLayout boxLay = new BoxLayout(leftPanel, BoxLayout.Y_AXIS);
leftPanel.setLayout(boxLay);
leftPanel.add(dragableJLabel);
leftPanel.add(dragableJButton);
leftPanel.add(dragableJTextField);
leftPanel.add(dragableJTextArea);
rightPanel.setPreferredSize(new Dimension(500,500));
rightPanel.setBorder(new EtchedBorder());
rightPanel.setTransferHandler(new ObjectTransferHandler());
contentPane.setLayout(new BorderLayout());
contentPane.add(leftPanel, "West");
contentPane.add(rightPanel, "Center");
public static void main(String[] args)
JFrame frame = new DragAndDropTest("Drag and Drop Test");
frame.pack();
frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
frame.setVisible(true);
}I wrote this code some time ago, so it won't be perfect but hopefully will give you some good ideas.
