tracking your database items from a form

the color of progressbar doesn't change because it follows operating system's theme color.
to modify color u need to remove this line from Program.cs file

//EnableVisualStyles() applies color and style of operating system to ur controls.
Application.EnableVisualStyles();

Note:-this wud remove operating system theme styles and colors of other elements in your project


update the progressbar from another thread.

to keep it red below 50% u need to set backcolor to red for every change in value.

hope this helped u :)
