Drag the following controls to the form:

1 textboxe, 10 buttons:

Change the textbox text property to 0

Let's also add 4 labels to the Form:

Start adding the labels from the left to the right on the form, then change their text property to 0:

You also should change the visible property of the labels to False. (The 4 labels will hide when you play the calculator)

Now let's add the code to the 10 buttons.

Scroll down to Click event and double click on the blank cell:

Then add the following highlighted code:

private void button10_Click(object sender, EventArgs e)

{

//check if the application need to clear the screen first



if (textBox1.Text == label2.Text)

// Hit Clear button: in this case it is button 17 (note that you might see an error because you havent added clear button,

//just ignore the error for a little bit

button17.PerformClick();

//Textbox 1 will display the text of the pressed button:

Button clickedButton = (Button)sender;

textBox1.Text = textBox1.Text + clickedButton.Text ;

}

Lets add the rest of the 5 math symbols: + - * / = to the form:

Change their text property to the math symbol like the picture below:

Programming the addition button: double click on + button and add the following highlighted code:

private void button13_Click(object sender, EventArgs e)

{

try

{

label2.Text = textBox1.Text;

double operand = Convert.ToDouble(label2.Text);

label4.Text = "+";

textBox1.Clear();

}

catch (Exception ex)

{

}

}


Programming the subtraction button: double click on - button and add the following highlighted code:

private void button14_Click(object sender, EventArgs e)

{

try

{

label2.Text = textBox1.Text;

double operand = Convert.ToDouble(label2.Text);

label4.Text = "-";

textBox1.Clear();

}

catch (Exception ex)

{

}

}


Programming the multiplication button, double click on the * button and add the following highlighted code:



private void button15_Click(object sender, EventArgs e)

{

try

{

label2.Text = textBox1.Text;

double operand = Convert.ToDouble(label2.Text);

label4.Text = "*";

textBox1.Clear();

}

catch (Exception ex)

{

}

}

Programming the division button, double click on the / button and add the following highlighted code:



private void button16_Click(object sender, EventArgs e)

{

try

{

label2.Text = textBox1.Text;

double operand = Convert.ToDouble(label2.Text);

label4.Text = "/";

textBox1.Clear();

}

catch (Exception ex)

{

}

}

Lets now program the equal button: double click on = button and add the following highlighted code:

private void button12_Click(object sender, EventArgs e)

{

try

{

double a = Convert.ToDouble(label1.Text);

double b = Convert.ToDouble(label2.Text);

double c = Convert.ToDouble(textBox1.Text);

{

if (label4.Text == "+")

{

a = b + c;

string d = Convert.ToString(a);

textBox1.Text = d;

label2.Text = textBox1.Text;

}

else if (label4.Text == "-")

{

a = b - c;

string f = Convert.ToString(a);

textBox1.Text = f;

label2.Text = textBox1.Text;

}

else if (label4.Text == "*")

{

a = b * c;

string f = Convert.ToString(a);

textBox1.Text = f;

label2.Text = textBox1.Text;

}

else if (label4.Text == "/")

{

a = b / c;

string f = Convert.ToString(a);

textBox1.Text = f;

label2.Text = textBox1.Text;

}



}

}

catch (Exception ex)

{



}





}

Lets add the last buttons to the form:

positive/negative button: +/-
Exit Button:

Clear Button

Decimal Button:


Programming the Decimal button:

private void button11_Click(object sender, EventArgs e)

{



textBox1.Text = textBox1.Text + ;

}

Programming the Positive/Negative button:

private void button19_Click(object sender, EventArgs e)

{

double a = Convert.ToDouble(textBox1.Text);

a = (-1) * a;

textBox1.Text = a.ToString();

}

Programming the Clear button:

private void button17_Click(object sender, EventArgs e)

{

textBox1.Clear();

label1.Text = "0";

label2.Text = "0";

label3.Text = "0";

label4.Text = "0";

}




Programming the Exit Button:

private void button18_Click(object sender, EventArgs e)

{

Application.Exit();

}
