Randomnes Tester - Ver 3 - C Sharp - 170524We

Randomnes Tester ver 3

.

(Written by me in c#)

Version: 170524We

.

Some years ago while working in the beautiful Borland Turbo C IDE and using Random numbers, for doing something, I thought why not test how many times any number comes in a list of Random numbers. So I then made a C program for testing that. At watching the result of that program I was a little surprised.

.

In first version that program generated 100 random numbers and displayed them on screen/CRT. I was surprised to see that some numbers were generated more than once and some never. So I made another version of that program and I changed it's working a little from the first version. Now although it was still generating random numbers between 0 and 99 but a lot of times and was storing how many times a number was getting generated in an array of 100 elements. In fact it was generating random numbers multiple of 100 times between 0 and 99. Now again I was surprised to see it's result. This time almost all numbers were generated 1 percent of times. All of this looked very interesting to me.

.

Few months ago I planned/decided to put that program on my this blog but because that program was in Pentium 3 and because that Pentium 3 was no longer working so after thinking and thinking I re-made that program and this time in c# in visual-studio 2010 for putting/sharing on my this blog. I named this new application 'RandomnesTester'.

.

Randomnes-tester’s user interface is simple and easy to use. At top right it shows a button with text 'Help'. Click this button for viewing Help information about this application. Next to 'Random number count' enter how many random numbers are required. It is a UInt32 field. Next to it is 'Max value' button. Click it to get max number entered in 'Random number count' field automatically. Helpful alert messages will display on invalid inputs. Click 'Start' button for starting process. Click 'Stop' button for stopping/cancelling process any time while it is running. On success result will display Under 'Randomnes Test Result'. Column 'Number' will show all numbers it generates from 0 to 99. Column 'Count' will show how many times each number is generated. Column 'Percentage' will show how many percent of times a number is generated. Under these is footer. Footer will show total numbers in 'Number' column under 'Number' column, total of 'Count' column under 'Count' column and total of 'Percentage' column under 'Percentage' column. Different text messages will show in bottom left telling what application is doing. Process status will show in text in bottom left and in Progressbar in bottom right.

Menu for TV - Ver 1 - C Sharp - 170506Sa

Menu for TV - Ver 1

.

(Proposed Menu for TV)

(Demo application is written by me in c# 2010)

Version: 170506Sa

.

Few years ago our Cable provider changed sequence of tv channels again and again in a few months and it made me very upset. Every time they were changing channel sequence I was re-arranging them back to, as much as possible, already memorised sequence numbers. But after that doing it again and again atleast once every year made me to think something else for solving this problem.

.

My idea was and still is to some how 'make' tv-menu or 'extend' already availabe tv-menu in tv sets. And in this new and/or extended tv-menu some-where (1) have options for searching tv-channels by typing their name, brand or type etc and (2) have lists of tv-channels orderd in different useful ways eg by-name, by-brand, by-type etc.

.

To test and view how menu arrangement look like i made an appllication in c# 2010. I implemented my idea through menu-item  'Channel', which is under menu-item 'TV Menu', with sub menu-items "Search", 'As is', 'Ordered' and 'User Preference' etc. Application and it's menu system is explained bellow with images where required or available.
