Windows Forms Basics

A Windows forms application is one that runs on the desktop computer. A Windows forms application will normally have a collection of controls such as labels, textboxes, list boxes, etc.

Windows Forms is a graphical user interface application programming interface (API) included as a part of Microsoft's .NET Framework. Winforms is a library for creating GUI applications.

Visual Basic Form is the container for all the controls that make up the user interface. Every window you see in a running visual basic application is a form, thus the terms form and window describe the same entity. Visual Studio creates a default form for you when you create a Windows Forms Application.

1. On the menu bar, choose File, New, Project. The dialog box should look like this.

2. Choose Visual C# in the Installed Templates list.

3. In the templates list, choose theWindows Forms Application icon. Name the new form WindowsFormsApplication1, and then choose the OK button.

Visual Studio creates a solution for your program. A solution acts as a container for all of the projects and files needed by your program.

4. Visual Studio opens an interface. The interface contains three windows: a main window, Solution Explorer, and the Properties window. which is shown below.

You can also display windows by using menu commands. On the menu bar, choose View, Properties Window or Solution Explorer.

  • Main window: In this window, you'll do most of your work, such as working with forms and editing code. In the illustration, the window shows a form in the Form Editor. At the top of the window, Form1.cs [Design] tab appear.
  • Solution Explorer window: In this window, you can view and navigate to all items in your solution. If you choose a file, the contents of the Properties window changes. If you open a code file, the code file or a designer for the code file appears. A designer is a visual surface onto which you can add controls such as buttons and lists. For Visual Studio forms, the designer is called the Windows Forms Designer.
  • Properties window: In this window, you can change the properties of items that you choose in the other windows. For example, if you choose Form1, you can change its title by setting the Text property, and you can change the background color by setting the Backcolor property.

5. On the menu bar, choose File, Save All .
