C# Forms (How it Works For Developers)

Introduction to Windows Form Project Type

Windows Forms, commonly referred to as "WinForms", is a graphical user interface (GUI) library in the .NET Framework and .NET Core Framework. With Windows Forms, developers can create rich, interactive desktop applications for Windows. This tutorial will walk you through the steps to create a new project on the basic Windows Forms app using Visual Studio, a popular integrated development environment (IDE) for .NET developers.

Setting Up Visual Studio

Before diving into creating your Windows Forms app, you'll need Visual Studio installed. It's the primary tool used to develop Windows Forms applications.

Installing Visual Studio

Download Visual Studio from the official Visual Studio website.

Run the installer and select the ".NET desktop development" workload. This includes the necessary tools for building Windows Forms applications.

Complete the installation process.

Starting a New Windows Forms Project

  1. Open Visual Studio.
  2. Go to the File option in the menu bar and select New > Project. This will open the 'new project dialog box'.
  3. In the dialog box, search for "Windows Forms App" and select it. Ensure you're choosing the right version based on whether you're using the .NET Core Framework or the older .NET Framework.
  4. Click on Next, give your project a name, and click Create in the dialog box.

You've now successfully created a new Windows Form application!

The Basics of Windows Forms

When you create a new Windows Form application in Visual Studio, a blank form titled 'Form1' will be displayed. This form is the canvas where you'll design your application's GUI.

Understanding the Visual Studio Interface

  • Solution Explorer: On the right side, the Solution Explorer shows all files and resources in your project. Double-click on 'Form1.cs' here to bring the form into view.
  • Properties Window: Below the Solution Explorer, the properties window displays the properties of the selected item on the form. Here, you can modify properties like size, color, text, etc.
  • Toolbox: On the left side, this contains all the controls (such as buttons, labels, text boxes) you can drag onto your form.

Adding Controls to Your Form

Adding controls to your form is as easy as dragging and dropping from the toolbox:

  1. Find the Button control in the toolbox and drag it onto your form. This is your 'button control'.
  2. Similarly, drag a Label control and a CheckBox control onto your form.
  3. Adjust their positions as needed.

Each of these controls has properties that can be adjusted in the properties window. For instance, select the button control and change its Text property to "Click Me".

Making Your Windows Forms App Interactive

An app is more than just its appearance; it needs functionality!

Adding Event Handlers to Controls

Double-click on the button control you added. Visual Studio will automatically create an event handler in the code behind the form.

In this event handler method, add the following code:

// This event handler changes the text of 'label1' when the button is clicked.
private void button1_Click(object sender, EventArgs e)
{
    label1.Text = "Button was clicked!";
}
// This event handler changes the text of 'label1' when the button is clicked.
private void button1_Click(object sender, EventArgs e)
{
    label1.Text = "Button was clicked!";
}
' This event handler changes the text of 'label1' when the button is clicked.
Private Sub button1_Click(ByVal sender As Object, ByVal e As EventArgs)
	label1.Text = "Button was clicked!"
End Sub
$vbLabelText   $csharpLabel

Now, every time you click the button in your Windows form application, the label's text will change to "Button was clicked!".

Running Your Application

Click on the green 'Start' button at the top or press F5. This will compile and run your application. The main method is the entry point of the app, and your form should appear on the screen. Try clicking the button to see your label's text change.

Advanced Controls and Features

Grouping Controls

Using the GroupBox control, you can group related controls, enhancing organization and user experience.

  1. From the toolbox, drag a GroupBox onto your form.
  2. Add other controls into this group by dragging them inside the GroupBox.

Using the MenuStrip Control

A MenuStrip control provides a menu bar for your Windows Forms app.

  1. Drag the MenuStrip control from the toolbox onto your form.
  2. Click on it to add menu items like "File", "Edit", etc.

Handling Multiple Forms

A real-world Windows Forms application often uses multiple forms.

  1. Right-click on your project in the solution explorer > Add > New Item.
  2. Choose "Windows Form", name it, and click Add.
  3. To open this new form from your main form, use:
// Opens 'Form2' when called.
private void OpenForm2()
{
    Form2 newForm = new Form2();
    newForm.Show();
}
// Opens 'Form2' when called.
private void OpenForm2()
{
    Form2 newForm = new Form2();
    newForm.Show();
}
' Opens 'Form2' when called.
Private Sub OpenForm2()
	Dim newForm As New Form2()
	newForm.Show()
End Sub
