Hii all

I created a progross bar
and it works fine


but i have a small problem

suppose that i am loading data on my screen form
and while the progress bar is working (e.g i reached 20%)
i change to another window when i return back to the screen
it stop the syncronysing operation and the data is loaded wihout affect on the progress bar and after the end of the operation the progress bar displays (100%)


this is the code that control the operation of the progress bar


Declare
  Previous_Width Number(10,5);
  tm_Name Varchar2(20);
  Vcount1 number;
  Vinc number;
  vREMAINDER3		NUMBER;	
  COUNTER NUMBER := 0;
Begin

Vinc := round(Vcount1/100);
IF (MOD(:SYSTEM.CURSOR_RECORD,Vinc) = 0 ) THEN
   
  Previous_Width := Get_Item_Property('Progress_Bar',Width);
		    
   If counter <= 100 Then
     
       Set_Item_Property('Progress_Bar',Width,  Previous_Width+ (Get_Item_Property('FRAME',Width)/100)));
        :Position := counter   || '%';
        Counter := counter +1;
	        
	 Synchronize;
	
    End If;
END IF;

It seems that synchronizing is canceled when Forms window lost the focus.

Perhaps you could create a timer which would execute this code in a matter of a second or two (using WHEN-TIMER-EXPIRED trigger).

I cannot use a timing method because the progress bar is working and progressed according to a number of records
not on a timing

OK, but you could DRAW the progress bar every second or two, i.e. call this piece of code (you posted in the first message). It would still calculate percent, but would draw it on screen when timer expired.

At least, I *imagine* that it might work. If not, sorry, but I don't have another idea at the moment (except that you don't open another window until this form finishes its job Smile).

can you tell me when you are calling this code... I mean you should have put this code in a procedure and calling it on each load of data?

Even if you don't change window, you can still encounter that problem. Synchronize seems not working because the screen display hangs.. I believe it's because the process uses much of cpu resources. after the process, the computer can now refresh the screen so you see it displayed 100%.

hi ,

I am testing this functionality....and i found that this behaviour is very random....sometimes this synchronization stops while sometimes it works fine...are you using any when-window-activated trigger.?
may be this problem is related to this trigger or some global variables which control the navigation condition of various screens.but currently i am not sure about this. Cool
thanks,
Yogen.
