JProgressBar question

I placed a progress bar on my form and it works almost fine.  
But the application.updateUI() slows everything down, It doesn’t makes any sense to add a this Progress bar.

Dose somebody have a suggestion, how I can speed this up?

Hi,

I guess you are you calling application.updateUI() in a loop and do that for every iteration.  
You better call the updateUI() at a larger interval (depending on your needs). You can do this by using the following code:

```auto
// start of loop

// only update every 50 iterations
// adjust accordingly to your own needs.
if ( iterationNr%50 == 0 ) {
     application.updateUI();
}

// end loop

```

Hope this helps.

Thank you, Robert.

It is much faster now.  
My next problem is that I want to set the maximum value from a Foundset whit.  
elements.bar\_progress.setMaximum(foundset.getSize())  
But it just sets the first 200 which are loaded in the foundset, how do I get the real size of the foundset?

Use the getFoundSetCount() function in the databaseManager:

```auto
var _nMax = databaseManager.getFoundSetCount(foundset)

```
