BLuetooth Door Lock - My project title, which means the embedded system operate to open the door lock when it received a correct password from the mobile via bluetooth...The embedded desgn in C programming languange and the mobile used Java(J2ME) to program...
The Concept - The embedded dsgn located near the door will send a electrical signal to the magnet at the door when it received a correct password from the mobile via bluetooth...The embedded board will be add a BT module (bluetooth to serial converter) to received a bluetooth signal from the mobile...Since the Java API support a protocol which can change the data through the serial port (RFCOMM protocol) so the embedded side can be program regularly with C programming...In the wireless side it provide SPP(Serial Port Profile), so any device compliant with this profile can exchange data through RFCOMM protocol...In Mobile side, J2ME will be a program to be write in this mobile..It need to include a password function that can send to the embedded side, which the embedded will check whether the password is authenticated to open the door...
-Any wrong method in this concept?..or other method need to be add?
-Is it possible to do it?
-Is it I need to use OBEX protocol?
-Any essential code that i can refer?

Hi,
I am running a form , when i click a button in the form a dll is called in which another form is appeared, now total two forms are running. In the task manager processes, i can see only the name of the first form. So i cannot able to find and kill the second from code using 'process.Kill'.
How can i able to find and kill the dll running from main form?
Thankyou,
YP

0) Killing is not ideal. We use that only for VB programmers and/or puppy haters.
1) You cannot see running dll's in the task manager, they're libraries that are linked to dynamically by executables.
2) You're loading the froging thing from your main form! Keep hold of the reference then you can release it cleanly later.

This is the etiquette:
- Post question.
- Wait for answer.
Go off and do some work and maybe later:
- Post question.
- Wait for answer.
Do not flood the forum with one liners that don't actual contain anything that can be resolved.

We had made a JFrame in NetBeans with placing a JTabbedPane in it. There are six tabs with many swing components in it.
Net Beans generated the code automatically in "JFrameClass.java"
That made one class. We changed the components access specifier to public.
Now We made a new class "SetTabPane" extending "JFrameClass.java" using JTabbedPane of class JFrameClass. While running the program it gives an error "java.lang.NullPointerException" on the line accessing the object of JTabbedPane.
Can you help us ???

No code, no help.
Go help yourself. If you're using Netbeans you can run in debug and find the /bad/ code.

There have a method, this one is free. Any more you can either pay for on rentacoder like the rest of the dross, or have a go and then ask for help with code that you can't get to work. When there is not even a single snippet showing what you have tried, you deserve the pit of hell and not anything useful.

Explain to me why I should help you.
The only answer you could possibly give me would be that your a Six Foot blonde with huge knockers who is willing to put out, which I doubt you are.

Hi am new to Java and programming in general. I have been trying to work on a project for school of which I have already posted ( a horrible version of the "program") though would just like to understand what I have done wrong. I don't like not knowing how to do stuff...
here is what I have posted :
/*
Write the program in Java (without a graphical user interface)
using a loan amount of $200,000 with an interest rate of 5.75% and
a 30 year term. Display the mortgage payment amount and then list the
loan balance and interest paid for each payment over the term of the loan.
If the list would scroll off the screen, use loops to display a partial list,
hesitate, and then display more of the list.
*/
package cr1;
import java.text.DecimalFormat;
/**
*
* @author
*/
public class CR1 {
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
DecimalFormat dollarAmount = new DecimalFormat("0.00");
double loan_amount = 200000.00;
int years = 30;
// calculation number of payments
int number_of_payments = years*12;
double intrest_rate = 5.75;
double monthly_intrest_rate = intrest_rate/100/12; // calculates monthly inrest rate
// monthly payment
double monthly_payment = monthly_intrest_rate/(1 - Math.pow(1+monthly_intrest_rate,-number_of_payments)) * loan_amount;
double ipaid = monthly_payment * .0575;
int paymentnumber = 0;
int payCounter = 0;
int pCounter = 0;
double loanbalance = loan_amount - number_of_payments;
while (loanbalance > 0) //
if (payCounter == 0)
{
System.out.println("Starting loan balance: $" + dollarAmount.format(loan_amount));
System.out.println("");
payCounter += 1;
pCounter += 1;
}
else
{
System.out.println("Payment Number:" + payCounter);
System.out.println("Monthly Payment:$"+dollarAmount.format (monthly_payment));
System.out.println("Loan Balance: $" +dollarAmount.format (loanbalance));
System.out.println("Intrest Paid:$ " +dollarAmount.format (ipaid));
loanbalance = loanbalance - monthly_payment;
payCounter ++;
pCounter += 1;
}
if (pCounter ==9 )
{
try
{
Thread.sleep(200000);
pCounter = 0;
}
catch(InterruptedException CR1)
{
// message prints with Java-generated data
}
}
else
{
System.out.println("Than you for using Billy Bakers Program. Have a good DAY!!!");
System.exit(0);
}
}
}
Though I know it is not outputting the information the right way..it is supposed to have 360 payments and its not. I don't know if there is a problem with my math, loop or both. Could someone explain to me what mine eyes cant ?
Thank you very much,
Bactos

Have you tried debugging it?
