hi all,

mbytes= 350 

Longreadnumberofkbytes= 250

readalert1file=90 //Text file data

DataLimit= 300  //Text file data

CurrentNumberofDataUsed= mbytes-Longreadnumberofkbytes;

ButtonField Save = new ButtonField ("Save",ButtonField.FOCUSABLE);
FieldChangeListener Listener = new FieldChangeListener() {
   public void fieldChanged(Field field, final int context) {
      ButtonField  Button = (ButtonField) field;
      if (Button.getLabel().equals("Save")){
         MCBT = new Thread(MakeChangesBackgroundThread);
         MCBT .start();
      }
   }
}
Save.setChangeListener(Listener); 
add(Save);

private Runnable MakeChangesBackgroundThread = new Runnable(){
   public void run(){
      while(true){
         long datalimitsum1 = Longreadalert1file/100;
         long finalansweralert1= datalimitsum1* LongDataLimit;
         if(!(readalert1file==null)){
	    if(!(readalert1file.equals(""))){
               if(finalansweralert1==CurrentNumberofDataUsed && CurrentNumberofDataUsed==finalansweralert1){
                  synchronized(UiApplication.getEventLock()){
                     System.out.println("Dialog thread starting");
		     UiEngine ui = Ui.getUiEngine();
		     Screen screen = new Dialog(Dialog.D_OK, "You Have Reached You'r "+readalert1file+"% alert",Dialog.OK, Bitmap.getPredefinedBitmap(Bitmap.EXCLAMATION),Manager.VERTICAL_SCROLL);
                     ui.pushGlobalScreen(screen, 1, UiEngine.GLOBAL_QUEUE);
		  }try{ 
                       Thread.sleep(30000/2);
		  }catch (InterruptedException e){
                       e.printStackTrace();
	          }
                }else{
                }
             }else{
             }
         }else{
         }
      }
   }
}

My Above code should push the global dialog when the

finalansweralert1

 is equal to 270. Can anyone please tell me What I am doing wrong?? TheDialog displays imediately after pushing the save button and not when 

finalansweralert1

is equal to

CurrentNumberofDataUsed

Thank you

If I understand this correctly, your question seems to be a straight Java question.  You have this statement:

               if(finalansweralert1==CurrentNumberofDataUsed && CurrentNumberofDataUsed==finalansweralert1){

and you think that CurrentNumberofDataUsed is 270 and finalansweralert1 is 0, and so the if should not be executed. 

Is this a correct statement of the problem?

To find out what is wrong with your logic, can you not just put a break point on the if statement and check what the values are?

hi peter, 

Some of my variables values werent correct they were displaying 0. Fixed it now. 

Thank you

Can you please mark as solved then? 

And perhaps try the debugging trick before posting? 

Cheers

I was stuck for two days on end, luckily a developer at the office was kind enough to assist me. i have marked the thread as solved. I only post something if i am stuck for days on end.

I understand that, but there is a huge difference between being stuck because the Java API is not doing what you expect and stuck because you have a logic error in your code.  The debugger is a a powerful tool for helping you trace logic errors, I was suggesting that you get familiar with that so that you do not have to post logic problems here again that could be solved using the debugger.  And you won't be stuck for days before posting....  Win for all!  Hope that is clear.  Cheers
