How to make programmable thermometer by  C# | Code

For Fahrenheit to Centigrade we set the value of Fahrenheit from track bar and convert this value into Centigrade using this formula C= (F-32)*(5/9).

private void trackBar1_Scroll(object sender, EventArgs e)

        {

            maskedTextBox1.Text = (trackBar1.Value).ToString();

            double change = (trackBar1.Value - 32) * (5.0 / 9.0);

            change = Math.Round(change, 2);

            maskedTextBox2.Text = change.ToString();

        }

For Centigrade to Fahrenheit we set the value of Centigrade from track bar and convert this value into Fahrenheit using this formula F= (C* (9/5)) +32.

private void trackBar2_Scroll_1(object sender, EventArgs e)

        {

            maskedTextBox3.Text = (trackBar2.Value).ToString();

            maskedTextBox4.Text = ((trackBar2.Value * (9.0 / 5.0)) + 32).ToString();

        }

How to calculate your GPA with simple application C#

  This is simplest GPA calculator in which user input the previous CGPA and previous Credit Hours (not for first semester these two fields) and no of new subjects and then enters the grade and credit hours of the subjects and insert in data grid view one by one if he by mistake put the wrong Grade or Credit Hours they can delete the wrong input by selecting the row and input again after input all Grades and Credit Hours then click on calculate button calculator calculate the new GPA and CGPA and display it.

Calculation code is:-

//to calculate GPA

            float Gradepoint = 0;

            int k = 0;

            //for read data from datagridview

            for (int i = 0; i < l - 1; i++)

            {

                //grade is A then CH * 4

                if (dataGridView1.Rows[i].Cells[1].Value.ToString() == "A")

 Gradepoint += 4 * float.Parse(dataGridView1.Rows[i].Cells[2].Value.ToString());

                //grade is B+ then CH * 3.5

                else if (dataGridView1.Rows[i].Cells[1].Value.ToString() == "B+")

Gradepoint += 7 * float.Parse(dataGridView1.Rows[i].Cells[2].Value.ToString()) / 2;

                //grade is B then CH * 3

                else if (dataGridView1.Rows[i].Cells[1].Value.ToString() == "B")

Gradepoint += 3 * float.Parse(dataGridView1.Rows[i].Cells[2].Value.ToString());

                //grade is C+ then CH * 2.5

                else if (dataGridView1.Rows[i].Cells[1].Value.ToString() == "C+")

Gradepoint += 5 * float.Parse(dataGridView1.Rows[i].Cells[2].Value.ToString()) / 2;

                //grade is C then CH * 2

                else if (dataGridView1.Rows[i].Cells[1].Value.ToString() == "C")

Gradepoint += 2 * float.Parse(dataGridView1.Rows[i].Cells[2].Value.ToString());

                //grade is D then CH * 1.5

                else if (dataGridView1.Rows[i].Cells[1].Value.ToString() == "D")

Gradepoint += 3 * float.Parse(dataGridView1.Rows[i].Cells[2].Value.ToString()) / 2;

                //adding total CH in k

                k += int.Parse(dataGridView1.Rows[i].Cells[2].Value.ToString());

            }

            //calculate the GPA and displaying maskedtextbox

            maskedTextBox5.Text = ((Gradepoint / k).ToString());

            //to calculate CGPA

            if (maskedTextBox1.Text == "" || maskedTextBox2.Text == "")

                maskedTextBox6.Text = maskedTextBox5.Text;

            else

            {

float h = float.Parse(maskedTextBox1.Text) * (int.Parse(maskedTextBox2.Text));

                h += Gradepoint;

                int CH = int.Parse(maskedTextBox2.Text) + k;

                maskedTextBox6.Text = (h / CH).ToString();

            }

Delete the selected Row code is:-

DialogResult Result = MessageBox.Show("Do You really want to Delete???",      "Confirmation", MessageBoxButtons.YesNo);

            if (Result == DialogResult.Yes)

            {

                dataGridView1.Rows.RemoveAt(dataGridView1.SelectedRows[0].Index);

                l--;

                label4.Text = "Grade of Subject ";

                label5.Text = "C H of Subject ";

                if (l <= k)

                {

                    label4.Text += l;

                    label5.Text += l;

                }

            }

If the user want to find the new GPA or CGPA then click on New button the New button reset all the field.

Code of New button:-

            dataGridView1.Rows.Clear();

            l = 1;

            k = 0;

            g = 0;

            label4.Text = "Grade of Subject ";

            label5.Text = "C H of Subject ";

            maskedTextBox3.ReadOnly = false;

            maskedTextBox1.Text = "";

            maskedTextBox2.Text = "";

            maskedTextBox3.Text = "";

            maskedTextBox5.Text = "";

            maskedTextBox6.Text = "";

            comboBox1.Text = "";

            comboBox2.Text = "";

            button2.Enabled = false;

            button1.Enabled = false;

How to make Simple Tic Tac Toe Game in C# windows application

How to make Simple Tic Tac Toe Game in C# windows application

This is simple Tic Tac Toe game in C# windows application in which we use 10 buttons, 9 buttons for game the text of these buttons by default null, and 1 for Reset.

The code of reset function is:

 public void reset()

               {

                     button1.Text = button2.Text =

                     button3.Text = button4.Text =

                     button5.Text = button6.Text =

                     button7.Text = button8.Text =

                     button9.Text = "";

                     i = 0;

                }

When we click on any button program first check the 2 conditions first the text of button is null and the how many times buttons are clicked.

  if (i < 9 && button1.Text == "")

Then check the value of (i) if the value of (i) is even then button text change into (X) else (O) and increase the value of (i).

  if (i % 2 == 0)

                    button1.Text = "X";

                else

                    button1.Text = "O";

                i++;

Then check the text of buttons in row, column or diagonal if the text of row, column or diagonal match then the text of team won the game and call the reset function.

  if (button2.Text == text && button3.Text == text)

                {

                    MessageBox.Show("Team " + text + " Won the Game");

                    reset();

                }

                else if (button4.Text == text && button7.Text == text)

                {

                    MessageBox.Show("Team " + text + " Won the Game");

                    reset();

                }

If the value of i=9 and text of any row, column or diagonal is not same then program display the message no one won the game.

  else if (i == 9)

                {

                    MessageBox.Show("No one Won the Game");

                    reset();

                }

Like this we code for all 9 buttons and enjoy the game.
