(adsbygoogle = window.adsbygoogle || []).push({}); Here's my first ever program for C#. I made it the same day I BARELY started C#.

I think I did good! I know this sounds weird but I got most of my experience from MW2 GSC scripting.. Even though C# differs every now and then vastly with functions, etc. from MW2 GSC.

Well, I'm uploading my whole source, I created a basic calculator.

Tell me what you think, what I can improve, and how I did on it! =D

Constructional criticism IS accepted. Here's my main code:

    

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Linq;

using System.Text;

using System.Windows.Forms;



namespace WindowsFormsApplication1

{

    public partial class Form1 : Form

    {

        public Form1()

        {

            InitializeComponent();

        }



        private void button1_Click(object sender, EventArgs e)

        {

            int i;

            string textStr1, textStr2;

            string val = "abcdefghijklmnopqrstuvwxyz/*+=!@#$%^&(){}][';><,";

            textStr1 = textBox1.Text;

            textStr2 = textBox2.Text;

            bool invalidVal;

            invalidVal = false;

            if (textStr1.Length == 0) invalidVal = true;

            if (textStr2.Length == 0) invalidVal = true;

            for (i = 0; i < textStr1.Length; i++)

            {

                foreach (char ch in val)

                {

                    if (textStr1[i] == Char.ToLower(ch))

                    {

                        invalidVal = true;

                        break;

                    }

                }

            }

            for (i = 0; i < textStr2.Length; i++)

            {

                foreach (char ch in val)

                {

                    if (textStr2[i] == Char.ToLower(ch))

                    {

                        invalidVal = true;

                        break;

                    }

                }

            }

            if (invalidVal == false)

            {

                progressBar1.Maximum = 100000;

                progressBar1.Minimum = 0;

                progressBar1.Value = 0;

                while (progressBar1.Value < progressBar1.Maximum) progressBar1.Value += 10;

                float a = Convert.ToSingle(textBox1.Text);

                float b = Convert.ToSingle(textBox2.Text);

                if (comboBox1.SelectedItem == "+") textBox3.Text = Convert.ToString(a + b);

                else if (comboBox1.SelectedItem == "-") textBox3.Text = Convert.ToString(a - b);

                else if (comboBox1.SelectedItem == "/") textBox3.Text = Convert.ToString(a / b);

                else if (comboBox1.SelectedItem == "*") textBox3.Text = Convert.ToString(a * b);

                else if (comboBox1.SelectedItem == "^")

                {

                    float num = a;

                    for (int x = 1; x < b; x++) num = num * a;

                    textBox3.Text = Convert.ToString(num);

                }

                string textStr3 = textBox3.Text;

            }

            else if (invalidVal == true) System.Windows.Forms.MessageBox.Show("Invalid Characters, or blank spaces have been inputted.");

        }



        private void redToolStripMenuItem_Click(object sender, EventArgs e)

        {

            this.BackColor = System.Drawing.Color.Red;

        }



        private void purpleToolStripMenuItem_Click(object sender, EventArgs e)

        {

            this.BackColor = System.Drawing.Color.Purple;

        }



        private void yellowToolStripMenuItem_Click(object sender, EventArgs e)

        {

            this.BackColor = System.Drawing.Color.Yellow;

        }



        private void orangeToolStripMenuItem_Click(object sender, EventArgs e)

        {

            this.BackColor = System.Drawing.Color.Orange;

        }

    }

}

Here's my source if you wanna see the actual program! The UPDATED program was built in bin\Release.

Enjoy! =D

Sounds kewl! =D

Maybe you could help train me with C++ coding :] or C#...or .bat ... or java ....any code works..

wow this is great for a first program keep it up bro :y:.

Don't know where to compile/edit C# but I gave it a thorough read through and it looks well constructed, and I noticed them colours

Nice, you finally got on the C# train :p... and dude your program sucks so bad that I had to use it to do my homework last night :carling:

:y:

I Know the perfect thing for ya.. You must login or register to view this content... find all his tutorials there.

Use "Visual Studio 2010 Express", C# is a good language i like it.

nice im taking this class next year then ap computer programming

C# IDE: SharpDevelop
C++ IDE: Code::Blocks

C# is a good language =D
