Keep ProgressBar to be seen


I set the value of ProgressBar in DataAvailable shell event, and the interval is 5 seconds.
MainWindow.CompareRunContainerScreen.CompResultAreaContainerScreen_01.CompRunProgressBar_01.Value = Val(TempArray(0))

It works fine.
The problem is that for every 5 seconds, the progressBar’s color disappeared and appeared again according to the value of the bar.
I want to keep it seen continuously without any disappearance.

Can you let me know how I can do it?
