LAMW problem with jProgressBar invalidate

[xinyiman]

Hi, I have a procedure that downloads more than 60,000 records from a json server and I would like to show the update through the progressbar. I use this code:

for ... do
begin

                         if (Self.ProgressBar1.Progress mod 100)=0 then
                         begin
                            Self.ProgressBar1.Invalidate;
                            //Self.Invalidate;
                         end;

end;

But it does not work. I see the progressbar update only when it has finished the whole loop. How do I resolve?
Thank you

Hi,
The operation you want is done using AsyncTask.
LAWM has a sample demo on this subject.
You can find it in the ....\lazandroidmodulewizard-master\demos\GUI\AppAsyncTaskDemo1  folder on your system.

I tried the example you suggested, but I have two problems.

1. If I don't put the sleep in the DoTask the program crashes

2. If in the DoTask I enter

jSqliteDataAccess1.InsertIntoTable(sql);             

crashes.
My need is to populate a sqlite db with more than 65000 records retrieved from a json on web server. I can download the json but I can't save it in sqlite and at the same time update the progress bar.

Forget it, I fixed myself with recursive jtimers where I process N records at a time.
