Plzzzz help me thru this
I have an application that contains:
an Access-database and a GUI that displays the values of the database.
Now I want to refresh the display after every 10 minutes. How can I do that? Can anybody help me ASAP.
you could create a runnable method that refreshes the display continuously. Assign it to a thread. After every time it is done refreshing, put the thread to sleep for 10 minutes. Using threads is covered in the online tutorial... if you aren't inclined to read that, say so

Write a program to manage assigned course to students.
The number of sections is unknown, and might change from a term to another.
We assume that each student is recognized by his name and ID, and may receive a grade for a specific course.
We also assume that each course has a name, an ID, and section name.
Using a list of classes, and a list of students in the same class,
- Register a new student to a new course
- Add a new course,
- Delete a course,
- Remove a student from a course
- Print all students in a course,
- Print all courses associated to some student,
- Assign a grade to a student
and this is my soulation

...Could you ask a specific question about some piece of code you're working on? A description like "I don't know how to complete it" does not tell me very much.

I just received photoshop elements 10 that I bought used thru Ebay, for my OSX Mac 10.5.8. I put the discs in my computer and nothing happens to help me download it. Can anyone help me with this instillation challenge?
Does your mac have an intel processor or PowerPC processor?
System requirements | Adobe Photoshop Elements
Did you insert the disk that is labeled mac os?
After you insert the disk, it should show on your desktop.
If you double click on the the disk icon on the desktop, does anything happen?

Hi Everyone...Please help me with this query...!
Please Help me with this doubt as I am unable to understand the logic...behind this code. It's a begineer level code but I need to understand the logic so that I am able to grasp knowledge. Thank you all for being supportive. Please help me.
//Assume class Demo is inherited from class SuperDemo...in other words class Demo extends SuperDemo
//Volume is a method declared in SuperDemo which returns an integer value
//weight is an integer vairable declared in the subclass which is Demo
class Example
public static void main(String qw[])
Demo ob1=new Demo(3,5,7,9);
//Calling Constructor of Demo which takes in 4 int parameters
SuperDemo ob2=new SuperDemo();
int vol;
vol=ob1.volume();
System.out.println("Volume of ob1 is " + vol);
System.out.println("Weight of ob1 is " + ob1.weight);
System.out.println();
ob2=ob1;
}Can someone please make me understand --- how is this possible and why !
If the above statement is valid then why not this one "System.out.println(ob2.weight);"
Thanks Thanks Thanks!u see the line wherein I am referencing the objectof
a subclass to the superclass...right? then why we
can't do System.out.println(ob2.weight)?You need to distinguish two things:
- the type of the object, which determines with the
object can do
- the type of the reference to the object, which
determines what you see that you can do
Both don't necessarily have to match. When you use a
SuperDemo reference (obj2) to access a Demo instance
(obj1), for all you know, the instance behind obj2 is
of type SuperDemo. That it's in reality of type Demo
is unknown to you. And usually, you don't care -
that's what polymorphism is about.
So you have a reference obj2 of type SuperDemo.
SuperDemo objects don't have weight, so you don't see
it - even though it is there.So from ur explanation wat I understand is - Even though u reference a subclass object to a superclass, u will only be able to access the members which are declared in the superclass thru the same...right

Please help me with this time capsule! Really let me down!
So first thanks for looking into this. I bought the TC from london but i live in Malta so i cannot go to apple store (that is why I need your help guys).
This is what happened in brief:
-Removed my existing router and managed to connect to internet (imac) via time capsule
-Tried to setup and managed and then started first back up
-It had to back up 179GB and like 2 GB was backed up already... i was like updating the details using airport utility and set up a password for my network... because the details updated time capsule refreshed and back up stopped
-Since then it was giving me the error that cannot connect due to network error
-It had like 3GB missing and I deleted that (moved file into trash) so it was like I refreshed it to start over with brand new back up
-Now I have managed to start it backing up again (it's so slow however) but as Im typing this... its backing up but the internet connection is getting lost every 1 minute and i have to go to airport from the bar and chose the network again
-I will not stay up all night waiting for it to finish so I already know what is going to happen... when I wake up I will see (again) the message that connection was lost (since I will not be awake refreshing and selecting the network every minute)
I am so dissapointed/___sbsstatic___/migration-images/migration-img-not-avail.png The fact that apparently i have stopped the fist back up (which was going well + fast) caused all these problems.
How do you actually reset/restore/format the TC to get it as brand new? I think that will solve the problem...
As I've told you guys you're my only hope. No apple store here
Thanks before hand and will look forward for the answer in the morning/___sbsstatic___/migration-images/migration-img-not-avail.png
Cheers & Hpy NYlaunch Airport Utility and under disk erase the TC hard drive(you seem to not have much value on it anyway) then if you have to change the name of the disk.
if you can connect TC to your computer thru ethernet connection and not wireless. 179 gigs is a lot of data to move. Ethernet should do you about 1.5 hrs to 2 hrs for the Time Machine backup.
Concerning the wireless problem I'd suspect some type of interference causing the disconnection. It can be just about anything for example, locating the TC too close to another router, vonage, computer, metal objects blocking or too near, TC location thru too many walls especially in N mode.
Hope this helps you. -

Question
I am not able to launch FF everytime i try to open it, it says FF has to submit a crash report,and restore yr tabs. I even tried doing that and the report was submitted too, but still FF did not start, and the problem still persists, please help me solve this issue
'''(in English)'''Hi Danny,
Per my understanding that you can't get the expect result by using the expression "=Count(Fields!TICKET_STATUS.Value=4) " to count the the TICKET_STATUS which value is 4, the result will returns the count of all the TICKET_STATUS values(206)
but not 180, right?
I have tested on my local environment and can reproduce the issue, the issue caused by you are using the count() function in the incorrect way, please modify the expression as below and have a test:
=COUNT(IIF(Fields!TICKET_STATUS.Value=4 ,1,Nothing))
or
=SUM(IIF(Fields!TICKET_STATUS=4,1,0))
If you still have any problem, please feel free to ask.
Regards,

That would mean IF there is an index on that column, it won't be useable... -

Can someone pls help me with this code
The method createScreen() creates the first screen wherein the user makes a selection if he wants all the data ,in a range or single data.The problem comes in when the user makes a selection of single.that then displays the singleScreen() method.Then the user has to input a key data like date or invoice no on the basis of which all the information for that set of data is selected.Now if the user inputs a wrong key that does not exist for the first time the program says invalid entry of data,after u click ok on the option pane it prompts him to enter the data again.But since then whenever the user inputs wrong data the program says wrong data but after displaying the singlescreen again does not wait for input from the user it again flashes the option pane with the invalid entry message.and this goes on doubling everytime the user inputs wrong data.the second wrong entry of data flashes the error message twice,the third wrong entry flashes the option pane message 4 times and so on.What actually happens is it does not wait at the singlescreen() for user to input data ,it straight goes into displaying the JOptionPane message for wrong data entry so we have to click the optiion pane twice,four times and so on.
Can someone pls help me with this!!!!!!!!!

}Hi,
I had a similar problem with a message dialog. Don't know if it is a bug, I was in a hurry and had no time to search the bug database... I found a solution by using keyPressed() and keyReleased() instead of keyTyped():
private boolean pressed = false;
public void keyPressed(KeyEvent e) {
pressed = true;
public void keyReleased(KeyEvent e) {
if (!pressed) {
e.consume();
return;
// Here you can test whatever key you want
//...I don't know if it will help you, but it worked for me.
Regards. -
