B4J Question DoEvents alternative

[rtek1000]

I saw a recommendation not to use DoEvents:

DoEvents should be avoided in all platforms. Use CallSubDelayed if you want to run something after the current sub finishes.

But the window freezes if you don't use something to wait a while. And Windows O.S. notifies you that the window is not responding.

I managed to read thousands of lines in a text file without freezes the window like this:
- I use a CallSubDelayed
- Inside the long loop I use a Sleep(0) command

I don't know if there's a better way to do this, but it worked here. If you don't use the Sleep(0) command, the window continues to freeze.

I'm converting a text file of tens of thousands of lines into an Excel spreadsheet.

Is there a more efficient way than using Sleep(0)?

Thank you.

BTW, the progress bar won't show anything without a call to Sleep. Better to remove it.

Remove progress bar?

The progress bar works normally here, without using Sleep.
