Hi,
What you need to effectively display and update a progress bar while doing some task is be able to tell at any given time:

1) how much have you processed until now
2) how much is it to be processed

So in the case of database rows, first start by getting a count of all the rows you have to get to the text file, then loop through each of them and update the value of the progress bar in each loop iteration by using the formula:

[number of rows processed until now] / [number of rows to be processed] * 100

I hope this helps
