When this program is run it asks for the coordinate grid points, then it processes that and the result is the run rise and slope.

A simple demostration of how to clear the console screen in at least Dev-C++ 4.9.8.0 (I don't know about the other since I've only tried it on this one, but may and probably works,, with few if at all minor adjustments), what more can I say, other than it's not …

Setcolor was entirely programmed by Mahen of Mauritius. Who have never wished of changing the Font colors of the Command Prompt on the fly. Well this is where Setcolor comes in handy. The main function of this program is to change the default Font color of your Command Prompt. The …

Shows a basic way to create a form with a wallpaper image on it. Also shows how to add a transparent label to blend in with the wallpaper. Getting the label to be transparent wasn't all that commodious! The wallpaper is generated using a texture brush and bitmap image. The …

Use layers to create plots within a browser. Each point to be plotted is rendered via a layer (using the DIV tag). Mozilla/Firefox/IE seem to handle thousands of layers without any problem. Can attach event handler to each point for additional interactivity. Snippet example is housed within a JSP at …

One more look at BCX basic code to show the qbasic programmers how they can modernize. This shows a function that converts an integer value to a binary string. Notice that with BCX basic you need to declare your variables. Makes the code a little easier to read too. Variable, …

In [url=http://www.daniweb.com/code/snippet149.html]Part 2[/url], you may have noticed that the bits representing the [i]value[/i] of an [font=courier new]unsigned int[/font] did not appear to match the bits representing the [i]object[/i]. This is because of the [i][url=http://en.wikipedia.org/wiki/Endianness]endianness[/url][/i] of my implementation. When it comes to displaying the bits of objects that take more space …

In [url=http://www.daniweb.com/code/snippet148.html]Part 1[/url], I chose [font=courier new]unsigned int[/font] as the type to use for displaying the bits of a value. The same general procedure can be done with other types as well. The biggest issue really is the expression which generates the most significant bit, for which there are a …

It is often instructive to display the bits of a value. (This is similar to 'converting' an integer to binary.) The way I have done this in this snippet is to start at the most significant bit and work your way through all the rest of the bits. (Continued in …

Yep. I have no life. Here's the simplest and stupidest form of C++ coding ever known to man kind...the change counter. What does it do? Count change :-)

This shows you how to create a Windows GUI program in BCX basic and embed the Media Player in the form. It will give you a fully functional player with a 30k executable size for your MP3 files. The needed header files and library files are included in the BCX …

New to me, but MS InternetExplorer does have COM support you can access from basic code. I had to test this out and make it work. We are using BCX basic, one of the successors to Qbasic.

Another look at BCX basic. Here we use COM support to manipulate Excel. In other words, from within the basic code we are entering a few numbers into the Excel spreadsheet and add them up. Of course you can do much more powerful stuff. With COM support you can also …

This is a very common task for a beginner programmer. Unfortunately many beginners do not seem to understand the question. First, know that binary, decimal, octal, hexadecimal, and others are simply [i]representations[/i] of values. The value of 123 (decimal) still has the same [i]value[/i] if it represented in hexadecimal (7B), …

I just had to do this to see how it would look like in the code field. This small prime number generator is written in BCX basic, a mildy more modern basic than Qbasic. With BCX basic you can throw in C and assembler code and it would actually compile …

This is a little program in QBasic which counts the number of characters in a string. Made by Buff - two errors removed by me. Thanks Buff.

Sooner or later a Csharp snippet had to appear. This one builds a form containing a set of buttons. A bitmap drawing area is used to draw a series of circles with random color, radius and center location. Your creation can be saved as a jpeg image file. You can …

Many of you know how I like to use sound to make the old computer box more interesting. The midi file packs a lot of neat instrumental music. It is very simple to play, even in a console application, using the winmm.lib file that comes with just about any Windows …

Log files are useful things. They are used in programs to display the values or variables or other useful information such as what the program is doing. This is useful is the program crashes at some point or is not behaving as it should. By writing values and events to …

This Delphi procedure sends the text contained in a multiline editbox (memo in Delphi lingo) to a printer. The font and font size can be specified.

An introduction to the Win32 GUI. The code creates a simple window that you can play with. Many parameters can be changed if you like! The unusual thing about windows apps is that rather than directly handling inputs (ie the position of the mouse / what control has focus ect...) …

Just to give you an idea what Delphi can do, here is a plot of the ever popular sin(x). I have put enough information into the code comments so you can build the form. The PaintBox Paint Event takes care of the plotting.

This is Delphi code, just testing if there is some interest.

This simple program will draw several randomly sized and colored lines on the screen. Makes a good screensaver!

A singly (sp) and a Doubly Linked list class to create linked lists. Can be used to make dynamic arrays and could also be templated to work with any data type (this is old code and i didnt know how to at the time). Has been extremely useful to me …

This program finds the solution of system of simulataneous equation Using GAUSS SEIDEL METHOD. This method is very popural among the students who studies Numerical Techniques.Though this program cant find the solution of every equations,it is widely used.This can only found the solutions of those equations which are Digonally dominant.

What is so easy to do in HTML gets quite involved in C. Once you learn to look past the standard GUI overhead it becomes more obvious. This example shows the effect of the mouse cursor moving across a label by changing foreground and background colors.

This snippet shows how to draw a red circle on a Windows form. Original code via BCX, modified to compile with Dev C++. The GUI code looks a little complex. Gets simpler, once you get past the required overhead. For those who need some hand holding with the Dev C++ …

This small program simply allows the user to call two different methods passing along an interger value to each. One method will output numbers from zero utnil that integer value using iteration. The other method outputs numbers from zero to that integer using recursion.

This is Similar to the Previous Snippet, but it puts indivdual pixels of different colors randomly on the screen. Also makes a nice screensaver!

returns TRUE or FALSE depending on whether or not a file exists

this is a wrapper around the AnimateWindow API. this allows random animations in a dialog. I just call it in the dialog's OnInitDialog() handler. The 'fade' effect has not been implemented because I didn't like the idea of having to call RedrawWindow or something like that because sometimes the borders …

Returns the name of a folder in a CString after allowing user to browse for it. This is just a wrapper around the SHBrowseForFolder API, but it's great for only allowing a user to browse for folders!

This programme can find the dimensions of cuboid and cylinder. In cuboids it can find missing dimensions also. Eg. if length is missing and volume is given it will find the length.

calculator using macros in C++

Adding this because it took literally an hour of searching before I found a code sample using fscanf that read more than just the first line of a file. This code assumes you're reading a file line by line that has the angle (int) followed by the Sine Value of …

Access 200,XP and 2003

Get the name of this computer

There are probably a few different version of this...here's the one I use which I find pretty simple:

Simple CLS for Resizing CTLs on a FRM

A simplistic program to compute the volume of a cylinder when its radius and length are input via MyInput.class

A simple demonstration of how MyInput.class can be used to input data from the keyboard. Computation is then done to compute the interest rate on a mortage.

A short example of passing variables between methods (functions).

The JOptionPane class is used to give the CompMortgage.java program a front-end GUI interface. The class is divided into numerous functions.

A single class consisting of multiple methods is used to demonstrate the robustness of keyboard input in Java. A try-catch block is used. The program graphically prints out a square root table by using JTextArea, JScrollPane and JOptionPane.

A demonstration of introductory object oriented programming. A class to define a circle object with radius, area, and perimeter parameters.

This program consists of two functions in one class. It is the driver program for the CircleClass.java file.

A program similar to CircleClass.java which defines a rectangle object. ClientProgram.java is the driver program for the Rectangle.java file.

Two classes which aim to demonstrate private and public members of a class. A static variable is used as an accumulator to keep track of the number of class objects which are created.
