If you make any kind of error, you will get error if you try to run this program. Area of a rectangle is the amount of space occupied by the rectangle. Program for Volume and Surface Area of Cube. Program to calculate the area of the rectangle. Using basic geometrical formulas: Area height x width and Perimiter (height + width) x 2 Then simply do this: int pmtr (Convert.ToInt32(textBox1.Text) + Convert.ToInt32(textBox2.Text)) 2 int area Convert.ToInt32(textBox1.Text) Convert.ToInt32(textBox2.Text) textBox3.Text pmtr.ToString() textBox4.Text area. Python Percentage increase in the total surface area of the cuboid. Find maximum volume of a cuboid from the given perimeter and area. Once they are multiplied, we again convert them to string using Convert.ToString. Calculate Volume, Curved Surface Area and Total Surface Area Of Cylinder. Since the text are strings, we need to first convert them into integers before we can multiply them. We need to add the following code in the button1_ClickĪrea.Text =Convert.ToString(Convert.ToInt32(length.Text) * Convert.ToInt32(width.Text)) Private void button1_Click(object sender, EventArgs e) 4,010 views This simple program calculates the area of a rectangle. Private void label1_Click(object sender, EventArgs e) Calculating an integral is traditionally done by. The only thing that we wanted to point out was that, upon double clicking the button, you see the following code. In particular, we have a strong focus on how to write Python code that is free of programming mistakes. We have a button, which on pressed will calculate and display the area. Basically, we have three text boxes, one each for length, width and area and three labels, just to the left of these three text boxes. We have shown the process of creating text boxes, labels and buttons in the following youtube. We will now write the same thing in graphics GUI format. We had already learned how to do this using the Command line in Console Application. In this tutorial we will learn a few more things about the Windows Form and in the next post we will write a program to calculate the area of a rectangle. Set the following properties for the controls on the form.ĭouble click on the sum button and write the following code in the click event of that button to calculate sum and display the result in result textbox.It is always a good thing to learn by real life examples. Give the name of the application and click on OK. If you do not need user interaction and simply want to specify the values in program, refer the below program. Program 2: In the above program, user would be asked to provide the length and width values. Open Visual Studio ->File -> New Project ->Visual C#-> select Windows Forms Application Output: Enter the length of Rectangle: 2 Enter the width of Rectangle: 8 Area of Rectangle is:16.0. When the rectangle is drawn, the pen is centered on the rectangle's boundary. The second argument passed to the Pen constructor indicates that the pen width is 5 pixels. The rectangle has a width of 100 and a height of 50. When user enters two numbers in to first two text boxes and clicks on button1 then sum has to be calculated for those two numbers and display the result in label4.Ĭreate a windows application and design the form as follows. The following example draws a rectangle with its upper-left corner at (10, 10). The following example creates a C# windows Form application with two text boxes, one button,four label controls. C# Windows Form Examples Example 1 : Add Two Numbers in C# Windows Form Application. Controls like a text box or a label are just some of the controls which can be added to a Windows Forms. The toolbox contains all the controls which can be added to a Windows Forms. Given a radius and an angle, the area of a sector can be calculated by multiplying the area of the entire circle by a ratio of the known angle to 360° or 2 radians, as shown in the following equation: area. On the left-hand side of Visual Studio, you will also see a ToolBox. A sector of a circle is essentially a proportion of the circle that is enclosed by two radii and an arc. Then, choose Create.Īfter you select your C# project template and name your file, Visual Studio opens a form for you. In the Configure your new project window, type or enter HelloWorld in the Project name box. (If you prefer, you can refine your search to quickly get to the template you want.) Lets create the same-purpose program using a user-defined function, areaOfRectangle(). On the Create a new project window, choose the Windows Forms App (.NET Framework) template for C#. Using the function to calculate the area of a rectangle. Take the last variable named perimeter and store the result of the calculation. Take another variable named width and store the width of the rectangle into this. Take a variable named length and store the length of the rectangle into this. The project type comes with all the template files you’ll need, before you’ve even added anything. The following are the steps that we need to follow to solve this problem. First, you’ll create a C# application project.
