Overview (TrackBar) Top
TrackBar is a scrollable control which allows the user to choose a value by moving the slider along the bar.
The TrackBar can be either horizontally or vertically.
The range of values can be set using Minimum and Maximum properties.
The TickFrequency property determines the ticks density.
An event named ValueChanged is raised whenever the value changes.
Example:
'Add a TrackBar named bar1.

bar1.New1("Form1",20,100,200,30,false)
bar1.Minimum = 20
