However, SetValueNoAnimation is the solution only to avoid animating from the current value (100, usually) to zero.
Then, however, in B4J-Release I still wasn't able to get what I wanted, the ProgressBar remains empty until the end of the processing (after which I set it as not visible).
It doesn't work adding a Sleep (which would slow down processing anyway) and neither using AnotherProgressBar1.UpdateGraphics.
P.S. The test project works, with a simple Sleep(5), the real project does not, not even by setting very high values in Sleep.
Okay, I'll find out the problem (I hope
).
