Hi. This is another version of the code i posted last year at:
This code will help you learn how to use a timer. It has tenths of a second, seconds, and minutes that add up, like a stop watch. I would really appreciate all e-mail and votes (I would like the votes to be based on how easy, my content, and how I explained how to make a stop watch).
Just a basic calculator, first program i've written. Would appreciate any feedback,tips etc.
This project will find the slope and the y-intercept of two given coordinate points with the equation: y = mx + b which may sound familiar if you are good in math or are taking algebra. Please report any bugs to me and I'll try to fix them. This is my second version because I found some big errors. I am sure this is fairly accurate. Votes and notes will be GREATLY appreciated! There is a little note. It won't make 8/8 = 1, it will just show it as 8/8. It will also not reduce and the y-intercept is in decimal form.
reduces fractions so you dont have to
This code will help in creating applications that will need multiplication of a 4 by 4 matrix.
This code is a demonstration of script control

This is another simple Base Converter. At least it has a different GUI! This is the first version that i've made myself fo learn base convertions. It has some Bugs but works.
calculator
The FormatDate function takes a date (String or Date data type) and reformats it into a custom string date format. It will recognize just about any String format as long as it DOESN'T include day names or date suffixes (e.g. Tuesday 9th). It will take its own output and convert it to another format (except for output containing day names or date suffixes). Recognized seperators within a date string are: space(s), forward slash, dash(minus), comma, decimal point and bold decimal point (char 149), period, colon and semi-colon. It assumes a String date's day/month order is the same as the users system settings (day/month or month/day). If the month portion is above 12 it will assume the reverse order if the day is below 12. FormatDate returns the reformatted date as a String.

Hi people! This is my first submission so please be gentle! It?s a simple little prog to convert binary to decimal and back again. Had to make the binary to decimal bit for college. Works with abnormally huge numbers. I couldn?t find any converters that worked with huge numbers on PSC. But then again I only looked for 5 seconds. Really Happy with this code cos it only took me 2 days to work out how to get it to go back to Binary.

So if anyone knows how to do this please comment below, Thanks. Ive sorted that now, thanks to Sien for helping me!
Purpose of this code is to develop a scientific calculator.
"Better than "Better than MS Calendar Control"
This program allows simple creation of bezier curves. Given the 'Control Points' (the points which a bezier curve is based upon - two end points and any others to affect the curve), the 'CalculateBezier' function will return the coordinates of a point anywhere along the curve. The front-end to the function just shows you what a bezier curve is, and the large capability of the function to accept as many control points as you want (the front-end limits it to 99, but the function will accept more if necessary). The code is marked at 'Advanced' level because of the complexity of the equations used, although programmers at the 'Intermediate' stage might be able to understand it.
The purpose of this submition is to refresh a programmers mind on how binary numbers work and help any user to learn binary numbers easly.
This code shows you how to left and right shift numbers. The concept is little used, and as such VB6 does not offer an easy way to do this. This code shows you the way to do it as if you were doing it by hand on paper (better way of learning if you ask me). Anyway, for you .Net users...2003 apparently has these functions built in by way of the '<<' and '>>' operators (as seen in Java, JavaScript, C, etc. I don't have 2003 .Net, so I can't exactly verify, other than I saw it on MSDN.
Just a simple Binary Clock...
Teach yourself to count in binary on your fingers.
Ok, I have adjusted the program to accept the info from the calender control value property (didn't know about that one previously) so that no matter what your systems date format is, the age calculations will be correct. I also added a registry entry to save the birthdate entered as suggested by Paul Turcksin. Thanks for all the advise Paul.

With this BigNumLib (big numbers library) you can do everything around large numbers (as strings):
It converts binary to decimal and decimal to binary.
BigNum Calculator by Robert Rayment. Does calculations on, up to, 1024 bit numbers (~310 dec & 256 hex digits). Operations on single numbers include shift left/right, roll left/right, Not, Factorial, Squared & Cubed. On two numbers - And, Or, Xor, Eqv, Imp, Div/Mod, Mul, Sub & Add. The full results can be displayed and saved to the clipboard or a file. All calculations are for positive integers only. Make sure to compile the program, particularly for large numbers. Machine code is used for some conversions to speed things up by a few seconds since they take much longer than calculations, principally for 4 digit factorials. For small numbers this has some educational value but very large numbers are just a curiosity, though apparently there is some use in encryption. Zip 27 KB.
This is a really BASIC and SIMPLE program for demonstrating how to deal with numbers in VB ,,, Comments PLZZZZZZZZZZZZ

Visual Basic doesn't provide a adding function with "hh:mm" result this code does it! :)
This code solves any DateTime difference calculations, by coverting any date that is between the year 0 and the year 10,000 into a decimal format in days. The time of day is added to the date in day format as a fraction of the day.
The reason I made this code was because I started to be interested in game programing. I realized that if the game is to be realistic, vectors are needed to forces like gravity and wind ect. This code will add 2D (on XY plane) and 3D (XYZ planes) vectors, subtract them. Get the Value from the velocity of the vector on the X -axis, and also for the Y & Z axis (Z only in 3D Vectors). One function called MovePoint2D will add a vector to a point (there is also function to move a point in 3D space). Last but not least ;), if one of the functions is giving two points, it will return a vector (yet again in both 2D and 3D). I hope this is helpful for anyone working with vectors to move a point.
Equation solver is a DLL project that provides objects that can solve equations entered as strings. This revision supports basic trig functions (sin/cos/tan) as well as the basic math operations. It also supports the use of variables in the equation (in fact, at this point, if you don't use at least one, it will crash & burn) I created it for use in a control, which when finished I will post here as well with links to & from.
This is a really simple API call I was playing with. What is does it gets Year, Month, Day or the Week, Day, Hour, Minute, Second and the coolest Millisecond. It'll also set it for whatever you choose using another API. Cool, 'eh?

This function is very usefull when we want to validate a date, entered by the user manually in a textfield, and format the Date in some predefined format.This function does the same thing but with greater flexibility .Means it allows user to enter date in a bit more flexible way (where sometimes date()function wont allow u)(allows formats like 2.3.4, 12|5|2045, 12-5-4, 2/12/04, 2\2\121 whichever way user likes) and then it automatically completes and validates it and then reformat the date according to predefined format which will be passed as an argument to this function.
This code will tell the user the distance between two XYZ coordinates.
Perform functions on complex numbers. Add, subtract, multiply, divide, take logarithms, sines, cosines, tangents, raise one complex number to the power of another. Program has a nice interface allowing the user to see the complex vectors interact. Though written in VB5, it is really an excercise in mathematics. The bas module is where the real meat of the program lies, all the code for the complex number manipulation. The forms are just the 'fluff' for the nice interface. Sorry, the code is not documented at all; just a spur of the moment kind of thing. Any comments or improvements would be greatly appreciated. Thanks in advance. Please direct to Soze99@aol.com
For those folk that play with EMMM stuff, finally something you can use. I got these calculation (entirely done in VB, not C) from a great guy somewhere in the US. It really helped me. Maybe it will help someone else in the world. The problem I had was that I had a hardware device that recorded information in EMMM format. This data could be downloaded through RS232, but for me to use this data in VB, I had to convert it from EMMM (2 byte float) to a data type "Single" (VB float). I do not think many people will be using it (maybe you prefer to use C).

Ever been to the restaurant Cracker Barrel and tried to win at that triangle game with the golf pegs? This program will solve the game when given any of the 15 pegs as a starting point. It creates a solution by trying every single possible combination of moves. Once the program has run, it will add all the possible combinations to a listbox, and sort each entry by the number of pegs that will remain -- the goal is to win by having only one peg remain. Entries starting with [1] mean that only one peg remains. After the brackets for each entry, the program explains how to get to a specific situation -- for instance, if it says 1W3, the peg in hole 1 should jump over peg 2 and end up in peg 3. Each jump is separated by an asterisk. For more information and a complete explanation, please visit http://www.celtickane.com/programming/code/cracker.php

This is a scientific calculator that can perform many calculations that can calculate like a Texas Instruments calculator. It can perform powers, square roots, logarithms, and trigonometry; simply add, subtract, multiply, and divide; and do other little things. You can also convert an expression to a fraction and round an expression to specified decimal places. You can switch between three modes of angle units: degrees, radians, and gradians. Using your keyboard, you can enter expressions by typing them into the input box, or by moving and clicking your mouse, you can just simply use the buttons below. I guess if an expression entered is way too complex, the calculator will return an error, otherwise it should work fine. Enjoy the power of this advanced calculator!

This code is made to calculate off peak hours when billing a customer. In this example, any hours that fall before 9am and after 9pm on weekdays, and all day saturday and all day sunday. For us, we charge time and a half for these hours. I looked all around psc to see if I could find a function to do this, but I didnt, so I wrote one. Now I know, this could probably be done a lot better, but that is a big reason for posting it here (the other is to give back to the psc community). I welcome all comments and suggestions to make this code better, because i know there will be. All i ask is that you keep it respectful Im sure there will be a lot of, 'what were you thinking' thoughts entering your mind. And yes, i know, this code isnt written the neatest, or the most efficient, but it works. So all I ask is politeness. With that said, let the comments begin. I know there are plenty of areas that could be done better. Im not really too concerned with votes, but if you feel that this is at all deserving, feel free. Also, read the unputs, returns, and assumes.

Nothing spectacular or ground breaking, but just a little piece of code I thought I would do in 20 minutes. After 'Fateha Rahman's attempts at writing this code, I felt my comments weren't really taking effect of improving their code much. So I decided to write this in 20 minutes of spare time to show how it should be done. This code shows 3 different methods of checking if a number is even or odd, and shows which is the fastest. It includes proper bench marking code with it.

This calculates interest made from, say a bank account. This may seem simple, yet nearly all programs that do the same thing have 1 thing missing and that is completely wrong. Interest is calculated on the total amount of money from the previous year. Most programs only calculate interest from the first year, not from the total of first year + next years interest and so on. Mine does.
This class contains the basic arithmetic operations (+ - * / mod) and a square root function for integer operands of virtually any size. A few helper functions are also included. There is no real limit on the number of digits but your memory size and time (up to a theoretical maximum of more than four thousand million digits). However, extracting for example the root of 10,000-digit number giving a result of 5,000 accurate(!!) digits will let you drink a cup of coffee while waiting (faster when compiled -- about 27 seconds on my 1800 Athlon). The Screenshot shows the square root of 2 with about 1000 digits. Download is 8 kB.

This takes a number (with or without decimal point) and compresses it into 4 bytes (or three if you dont need the decimal places part). If a number is smaller than 0 then it will not compress (unless you turn it into a positive number and add another byte to it. This will give you 4 numbers in 4 textboxes. If you then wanted to save it to a file you could then use the chr() function to get a single character back for each byte.
Enter any number, then it will show you how many time you enter a number, the average

Polar Graph is truly amazing. At first, I thought it was just a simple graph but when I start to program it and add some settings so that I can able to change the appearance of the graph, I was amazed with the result. I have found out that some of the games and animation that I have seen they have used polar graph. I also found out that it has many uses, of course, it depends on you. In my submission, I have included three programs (1) the polar graph itself, (2) games and (3) animation. If you want to learn more about polar graph then try to use this code. If you are a game programmer or if you like to make a very nice animation then this is what you are looking for. By the way, the games that I have included also help you on how to create a simple game.

I have seen a few prime number checkers on here. In fact i used most of the code from another author (sorry i didn't get your name, so if you see this, i say good work!) The only difference is that it uses a timer and just goes through checking every single number without you having to input anything. there are two listboxes, and when it finds a prime number, it puts it in the first list, and when it finds a number that isn't prime, it lists it in another box. really not that usefull. but kind of fun, i guess.

This program is a simple Quadratic Equation solver which, aside from finding the x intercepts (whether real or imaginary), it graphs the equation and makes a table of values, and shows the quadratic equation with your values calculated inside. I submitted this program as an example for beginners on the correct use of Object Names, Variable Names, Etc (Based on the Leswinski Naming System). This program of course teaches you how to graph an equation in a picture box, and use a list box. The program uses a Variable Array to store the Y Values of the graph, thereby demonstrating how to utilize a variable array.
This code solves a quadratic equation inputted and returns the actual root in simplist radical form. Unlike the quadratic solvers here on PSC, this one solves for actual roots (in radical form), not just for long decimals. You can also have imaginary roots also in simplist radical form.
This code gives an example of a program that solves quadratic equations using the quadratic formula. It tells you roots, the nature of the roots, the discriminant, the axis of symmetry, and the turning point. Useful for helping you with your math homework.
This program will solve any quadratic equation, even ones with imaginary roots. I've used the bisection method for finding a square root instead of the standard vb sqr() function, as it's slightly faster, and I can control the accuracy.
This program will take a quadratic equation entered in the form y=ax^2+bx+c and find the both roots of the equation wether they be the same, different, or imaginary. It will then find the first derivative of the equation, along with the vertex, and also convert the equation to vertex form (y=k(x-p)^2+q).

Convolution of Two input signals by sherif rofael , First Time in planet source code , advanced code ,
As you know, computers generate a pseudo set of random numbers. This is unavoidable in a digital environment. A coin toss is in reality an analog event. The only way to have a truly random number generator is by introducing an analog to digital conversion. This program does exactly that. The analog random event sampled is sound frequency and by using a microphone, a completely random set of numbers (seeds) are generated. The audio FFT is borrowed from PSC. Many methods have been suggested to perform this task. Some have used random data sets as seeds. Others have sampled mouse movement. A website provides realtime random atmospheric data (www.random.org). There has even been a proposal to include a cesium chip in all computers eventually as it decays in a random fashion. My method seems foolproof as long as a microphone is set at a reasonable sensitivity and the environment is noisey. The importance of true randomization cannot be overemphasized as this is essential for the scientific method and in clinical studies. My application, which will be posted soon, is simpler and more abstruse. I intend to use this random generator to identify variations in our collective unconscious, an idea I heard about on National Geographic. ---Update(08-22-07):Instability added, minor changes ---Update (08-25-07): Algorithm improved, Added Temporal Instability monitor with raw data, Chi Squared Statistic with table to assess randomness. You may compare a Simulation (using the Timer seed) versus my Hardware (sound) Seed, although significant difference will require over about 1 million flips. The instability data may be viewed in 15 minute intervals for about 1 year using MSChart32. Rudimentary help file with more to follow.

Visual Basic Program that computes flux and etc. of THREE-LEGGED CORE for ELECTRO-MECHANICAL ENERGY CONVERSION.
This program has been written by two authors:
This is a String Parser / Math Formula Evaluator OCX-Control. It contains over 100 functions: simple add / subtract, mult and div, roots, exponentiation and logarithm, math, trig and stat functions, conversions, LCD, SCM, primes, faculty, dates and times, differentiation and integratation and l.b.n.l. some functions for fuzzy sets and for plotting curves. All functions can be combined into huge formulae like for exam?le Sin(33?+12'+21")*pi-e+3.3e4+sqr(5*(21-9)) which incidentally returns 33006.748173093. The Control also supports formulae with letters or names instead of numbers like r?*pi Whenever the Control detects a token in a formula, it will query the value for the token and the client may supply anything that is a valid formula including further tokens, thus enabling chain-calculations. A user accessible result stack is also implemented. Anyway - it's a treasure chest for math routines (for example containes a very fast prime number generator which can compute 100,000 primes in less than 2 (two!!!) seconds on an AMD Athlon(TM) XP1800+). A cross-linked help file is included as well as two sample proggies to test and demonstrate the capabilities. Download is 36 kB.
I wrote this to show ppl how to take a number like 126 and make it into 01111101. It now also calculates the binary for say the word "hello". There are still 2 ways now to calculate the binary. 1 new one that can change the base also. Other options like writing binary to files and more.
Dug this up; had done it over a year ago. Another unit converter! A few of these around, so here's mine!
Couldnt find anything at all on this site about epoc time so i made in app for it. Enjoy.
3DGraphCalc is a 3D-graph viewer. You type in an equation in the form Z=..(X & Y) and you can then drag the graph around with the mouse. The use intended is dragging at a low Delta-value (Detail-level of grid), and when you've found the preferred angle of view, change the Delta-values to e.g. 50 and hit 'Graph'.
This math library handles 2D Vectors, 3D Vectors, 4D Vectors, 3x3 Matrix, 4x4 Matrix, Color, and Quaternions.
Will convert any number, decimal, binary or hex into the other 2 instantly, capable of minus numbers, decimal numbers, 2's compliment, the lot.
This program can convert any base (Binary, Octal, Decimal or Hexidecimal) to any base (Binary, Octal, Decimal or Hexidecimal). Numbers are accurate till a decimal equivelant of 999,999,999,999,999. Nothing too fancy, but is the first code I have seen on PSC that allows ou to toggle with ease between each of the base types after entering initial number in any base type. Also shows you how to limit a text box character entry to specific letters or numbers or even a specific length in bytes. Also please note that if you have Windows 2000 or XP, you can do this same thing with the included calculator in advanced mode. If you have Windows 98 or NT 4.0 this is a very handy converter, since those OSes cannot convert numbers greater than a Decimal 4,294,967,295. Enjoy the code and feel free to use any part of it for your programs.
This is a nice idea to create unique random numbers, in a fixed interval. This module could be very useful for your security module or in game programming or make runtime GUI and so on?.
ConvDate - Convert a date from one format to another (any date format I could think of is supported).
This module is a collection of various time functions, including the generation of GMT offset UNIX Epoch timestamps, Leap Year calculation, Days In Month calculation, and the completely unique GetTimeZoneOffset(), GetCurrentTimeZoneOffset() and isDaylightSavings() functions! I was unable to find any VB code for timestamp generation, so I had to make my own! Have you ever needed to compare dates that were created in two different countries? If so then you've probably run into the differences in dates in various regions of the world. The US formats dates as "mm/dd/yy" where as most of the rest of the world uses "dd/mm/yy". This is all fine and good, until you need to compare one to the other. According to VB's documentation, the date format is defined by the local systems settings. This has the effect of improper comparison when equating dates generated in two different regions. IE - is CDate("3/4/03") March 4th or April 3rd? VB makes the assumption that the date was generated on the local system, so if the local system's format is different then the system that generated the date it will be incorrect. It becomes even more fun when dealing with other languages! CDate("Mar 4, 2003") will generate an error on a non English machine as "Mar" is not a recognized month or abbreviation. Utilizing a GMT offset UNIX Epoch timestamp can avert this issue. The timestamp is the number of seconds that have elapsed since the epoch (January 1 1970 00:00:00 GMT). So instead of storing "3/4/03" you store "1046700000" which is the number of seconds between March 4th, 2003 and the epoch. Best of all, this module allows you to convert back from a timestamp into a date variable, allowing you to format it for the local user. ** In a nutshell, utilizing a timestamp in place of a locally formatted date will allow you to correctly compare dates no matter what language or format was used during the creation of either date you're attempting to compare. ** The other unique functionality of this module is the GetTimeZoneOffset(), GetCurrentTimeZoneOffset() and isDaylightSavings() functions. These allow you to determine the Time Zone Offset and Current Time Zone Offset of the local system. IE - Canberra, Australia is GMT + 10:00, so 10 is Canberra's Time Zone Offset. During summer daylight savings, Canberra's Current Time Zone Offset is 9. If you didn't follow that, then you'll probably never need this functionality (but it's in here if you do)! The rest of the functions are pretty standard, though well-commented and optimized functions concerning leap year and days in a month calculation. The module is pretty well tested, but your mileage may vary. Please leave a comment or send an email if you find a bug or have a new feature to add or request! Thank and enjoy! UPDATED - (Finially) fixed the leap year bug. Please let me know if you find any issues!

This program generates perfect numbers. If you do not know what a perfect number is I will try to explain. 6 is a perfect number because 6=1x6 or 2x3 and 1 + 2 + 3 = 6. 28 is a perfect number because 28=1x28 or 2x14 or 4x7 = 1 + 2 + 1 4 + 4 + 7 = 28. For more information on perfect numbers go to http://www.resonance-pub.com/perfectnums.htm . Also here is some code, unfortunately in C, that it does almost the same thing. http://pw1.netcom.com/~hjsmith/Perfect/PerfeCpp.html . If you can do it faster drop me a line.

Equation Evaluator (EE) acts like a calculator in that a user can type in an equation, EE will interpret (parse) the equation, and calculate a result. Numerous mathematical functions (sine, integer, and so on) are predefined. Unlike most calculators, EE can be used as a subroutine in other programs, and is specially coded to evaluate the equation efficiently with different variable values. The same equation can be evaluated thousands of times (with different input values) in a fraction of a second!
The purpose of this code is to use the least squares method in order to predict a new response variable gained through the input variable
The short description would be how to demonstrate how to produce a random number among a set, with an even probability to get any given member in the set. Usual random number generators I see on here are too simple and end up with maximum and minimum ranges of the desired set being half as likely to be generated as anything in the middle. Obviously the members in the middle will be that much more likely to occur, resulting in a set of random numbers that isn't quite right.
This function performs ASTM E29-93A standard rounding on real numbers for numbers containing 15 or less digits.
