Fancy Progressbar - Ver 2 |
| (Demo for Progressbar, Prime numbers, Dynamic Form.) |

| I
found a Project in working folder of C# 2010 with name 'FancyProgressbar' which
was written by me a few years ago. I opened it ran it and went through it's
code. That project was collection of some fancy looking Progressbars. After
running that project for some time I made another project for sharing here
and named it 'FancyProgressbar-02'. |
| This
project is a demo project. First it demonstrates a fancy looking Progressbar. Second it demonstrates how to find prime numbers between 2 numbers with a gap of 100000000. Third it demonstrates how to create a form programmatically and use it to show Help information.
|
| . |
| A simple fancy
looking progressbar:
|
|
Fancy looking progressbar is actually made of one
TableLayoutPanel and two Progressbars. First Progressbar with it's Style set to
ProgressBarStyle.Continuous and second Progressbar with it's Style set to
ProgressBarStyle.Marquee. Resultant Progressbar is made to look fancier by playing with some Properties of these 3 controls.
It's use is demonstrated during finding of prime numbers. |
| . |
| Finding Prime numbers:
|
| Application runs a long process for finding prime numbers
between 2 randomly generated numbers with a gap of 100000000 and updates fancy progressbar based on calculated percentage
of work done by that process for each number it processes. Method for finding prime number is not optimized for speed or space. It is used here for having a long process for Fancy progressbar demo.

Creating Form programmatically:
|
|
Help information is displayed through a form created
dynamically / programmatically on the fly. First Form is created second a
control is added, Label in this case, third some properties of Form and Label
are set according
to needs (like Help info to Text property of Label) and fourth form
with Help information is displayed. |

are the screen shots of 'Fancy Progressbar - Ver 02' application with explanation.

|
| Application's
Help form looks
like this and it is displayed when 'Show Help' button is clicked. It displays some basic information about application. Working of main Form is not
blocked by display of Help form. Help window uses
different color on each load which it randomly selects from "Black, Blue, Green,
Purple, DarkOrange, Red and DarkCyan". I used creation date of the original project in Help info. |

|
| Application looks
like this when 'Start' button is clicked and application starts
finding prime numbers between 2 randomly generated numbers. 'Start' button
becomes disabled and 'Stop' button becomes enabled. In status line application shows
that it is 'Busy...' and percentage of job done by progressbar and percentage
number. It also shows number of Primes found and Primes found percentage in form. |

|
| Application looks
like this when Job is completed. 'Start' button becomes enabled again and 'Stop'
button becomes disabled. In status line it shows 'Done.' and Progressbar and
percentage label shows that 100% job is completed. Total Primes found and Primes
found percentage are shown in different fields of form. |

|
| Application looks
like this when 'Stop' button is clicked. On doing so application stops doing
it's job and shows 'Stopped.' in status line. 'Start' button gets enabled and
'Stop' button gets disabled. |
