Please, help me
A ProgressBar is a control to show progress. It is not possible to enter some kind of value with it. You cannot use ProgressBar as a TrackBar. The latter one is designed for it. If you don't like the appearance of the TrackBar, check out the internet for third-party components. Some will cost money, some are probably free.
Maybe this is what for you: Owner drawn track bar example
