I need to know how to create a bar that will track the quantity of items in my table in mysql..... such that it shows green when its above 50% and red when its below... any ideas... am doing it in c#

推荐答案

中执行此操作，进度条的颜色不变，因为它遵循操作系统的主题颜色.
修改颜色，您需要从Program.cs文件中删除此行

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();

注意:-此wud会删除项目中其他元素的操作系统主题样式和颜色


从另一个线程更新进度条.

若要将其红色保持在50％以下，则每次值更改时都需要将背景色设置为红色.

希望这对您有所帮助:)

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 :)

尝试 ProgressBar [ ^ ].
