Prime numbers generator - 6 - C Sharp - 1 of 2

Prime numbers generator - 6 [1/2] (Finds prime numbers between 2 and 32000000002 - c#) . Once upon a time a few decades ago I was frequent visitor of "Liaquat National Memorial Library - Karachi". I do not actually remember now how and why I went their for the first time. But I do remember that I continued going there for a few years. Although books on computer programming were my main interest but I enjoyed reading books on arts etc and different news papers as well. Books on "Lisp" and "Prolog" i studied there for the first time, but my main interest was books on "C" programming language and there were a lot of good quality books available there on C. Environment of "Liaquat National Memorial Library" was also very good calm and peaceful. After a few visits I learned that if I do not come early then surely I will not get chair in the huge reading hall. It was great to know that "Liaquat National Memorial Library" was in huge demand. Therefore, after knowing that, when ever I went, I went early. Because "Liaquat National Memorial Library" is located beside PTV Karachi therefore during coming and going I also had some glimpses of TV stars of that time eg "Subhani ba Yunus" etc. As far as I do remember I also saw famous movie star of Pakistan "Mohammad Ali" one afternoon standing with someone near entrance steps of library building. I think he was minister at that time also. Then time was around afternoon and I was mentally very busy and/or occupied in getting photostat of some chapters of computer book on Unix. Otherwise I would have requested for his autograph. He was tall  with pinkish white in color and had a pleasant smile on his face. I think I missed the opportunity. Back to topic. On one visit to "Liaquat National Memorial Library" I requested for "Guinness book of world records". And in that book for the first time I came to know about competition for finding prime number with larger number of digits than number of digits in any already known prime number. I knew how to find weather a number is prime or not so automatically an idea visited my mind to find some prime numbers on computer myself. Since then I tried different softwares available to me on different times for making applications for finding as many prime numbers as possible. The  list of softwares I used is as follows: Turbo C ver. 2 ON Pentium 2 and Pentium 3 Html and JScript ON Pentium 4 GCC ON Pentium 3 and i5 C# 6 ON Pentium 3 C# 2008 ON Pentium 4 C# 2010 ON i5 And on different ocations in different softwares I tried different methods for finding prime numbers eg long-hand-division-method, sieve etc. Also I kept researching on net and there I found pages on some sites displaying first few prime numbers eg 1st million prime numbers etc. I said Ok . . . I am also finding prime numbers, a lot of prime numbers and saving them on my pc's HDD. Why not I put prime numbers found by me, although I am not first to find them, on net some where some day. Therefore I re-ran current version of the application I made for finding primes to find prime numbers under different upper limits and found that for upper limit of 20000000 number of prime numbers is nearly above ONE Million. Some out puts of those searches I am sharing bellow. So far the maximum I reached for continuous list of prime numbers is: Range......................: [2 and 32000000002] inclusive Prime numbers found.: [1382799415] Largest prime number: [31999999987] Following is the list of first "6542" prime numbers, under 2^16, I found using software made by me using C# 2010.  I used this upper limit because it reminds me of "unsigned int" of 16 bit computers. . .

Console BarMenu - 3 - C Sharp

Console BarMenu - 3 (DOS era text-mode style Colorful Bar-Menu in c#) . A few decades ago during time of DOS 3 days making bar-menu in text or graphic mode was an advance cum fancy topic. What I remember now I then wrote a .prg program for making 'bar-menu' in 'dBase III Plus' on PC of institute and also impressed my friends, lab assistants and teachers. That .prg was first program I wrote for making bar-menu. Now it's print-out is still available in my archive of old print-outs or not I do not know. I am not trying to know either. So in memory of that 'Bar-Menu' program, I made for the first time in 'dBase III Plus' then, I made a Console project in C Sharp now. Salient  features of above mentioned c# project are as follows: (A) Display bar-menu. (B) Provide menu-item selection mechanism through navigation keys like Up-arrow, Down-arrow, Home, End and Enter keys. (C) Process menu-item selection and perform action accordingly. (D) Return back to menu at end of action processed. (E) Provide mechanism for exiting from 'bar-menu' and application. . Then I tried and made the above required project. Code for achieving above task is simple and is described as follows. (1) First menu processing method is called. There must be one such method per menu. (2) Then from menu processing method menu-driver method is called with information like menu-item-list etc. (3) Then in menu-driver things happen in following sequence: (3a) First menu is displayed. (3b) Then user-input is taken. (3c) Then user-input is processed based on input key as follows: (3c1) Navigation key: Selected menuitem index is updated. (3c2) Enter key: Current menuitem index is selected for returning. (3c3) Escape key: Menu exit code is selected for returning. (3c4) If user input is not Escape-Key or Enter-Key go back to step 3a. (3c5) Menu-driver exits when user-input is Escape-Key or Enter-Key. (4) Back in menu processing method returned value is processed as follows: (4a) Respective methods are called according to returned value. On return control goes back to step 2. (4b) Else menu exits when selection code is Escape-Key. . Keys used by menu are displayed in menu footer and are described in the following: Navigation: Down-arrow key for next menuitem. Up-arrow key for previous menuitem. Home key for First menuitem. End key for last menuitem. Selection: Ente key for selecting current menuitem. Exit: Escape key for exiting menu. . Following is the C# code of the project I described above. It is not so simple or easy to understand. But it is full of helpful comments throughout it. . .
