Lesson 1: Adding and Configuring Windows Forms

Lesson 1: Adding and Configuring Windows Forms

This lesson describes how to create and configure Windows Forms You will learn how to create forms and refer to them in code, alter the visual properties of the form, and control the behavior of the form at run time

After this lesson, you will be able to:

■ Add a Windows Form to a project at design time

■ Add a new Windows Form at run time

■ Resize a window at design time or run time

■ Identify and set the properties that determine a form’s appearance and behavior at run time

■ Refer to the default instance of a form in code

■ Create a non-rectangular form

Estimated lesson time: 45 minutes

Overview of Windows Forms

Windows Forms are the basic building block of the user interface They provide a container that hosts controls and menus and allow you to present an application in

a familiar and consistent fashion Forms can receive user input in the form of key­strokes or mouse interactions and can display data to the user through hosted con­trols Although it is possible to create applications that do not contain forms, such

as console applications or services, most applications that require sustained user interaction will include at least one Windows Form, and complex applications fre­quently require several forms to allow the program to execute in a consistent and logical fashion

When you create a new Windows Forms project, a form named Form1 is added to your project by default You can edit your form by adding controls and other visual elements in the designer, which is a graphic representation of a designable, visual ele­

ment (such as a Form) that appears in the Visual Studio Integrated Development Envi­

ronment (IDE) The Visual Studio IDE is shown in Figure 1-1

Figure 1-1 A Windows Form in the Visual Studio IDE

Adding Forms to Your Project

Most projects will require more than one form You can add and configure additional forms at design time, or you can create instances of pre-designed forms in code at run time

Lesson 1: Adding and Configuring Windows Forms

� To access the default instance of a form at run time (Visual Basic only)

1 Refer to the form by its name You can call methods or access properties from

this default instance For example:

' VB

2 If referring to a form from within that form’s code, you cannot use the default

instance You must use the special keyword Me (Visual Basic) or this (C#) to

access the form’s properties and methods

� To access a form’s methods and properties from inside its code

1 Use the keyword Me (Visual Basic) or this( C#) For example:

' VB

Me.Text = "J and J's Wine Shop – Main Page"

// C#

this.Text = "J and J's Wine Shop – Main Page";

2 You can also create new instances of forms at run time by declaring a variable

that represents a type of form and creating an instance of that form

� To add a form to your application at run time

1 Declare and instantiate a variable that represents your form This example assumes

that you have already designed a form named Form1 in your project:

' VB

// C#

Properties of Windows Forms

The visual appearance of your user interface is an important part of your application

A user interface that is poorly designed is difficult to learn and will, therefore, increase training time and expense You can modify the appearance of your user interface by using Windows Forms properties

Figure 1-2 The Properties window

Table 1-1 summarizes some of the Windows Forms properties that are important in the look and feel of the application Note that this is not an exhaustive list of all Windows Forms properties but, rather, a selected subset

other forms that do not have this property set to True

Modifying the Look and Feel of the Form

You can use the Property Grid to set properties of the form at design time Properties set in this manner will retain their values until the application starts, at which time

fies any subvalues of the property and assign it to the property as shown in the fol­lowing pseudocode example:

' VB

PropertyY = New Class(value,value)

// C#

PropertyY = new Class(value,value);

The (Name) property, which represents the name of the Form class, is an exception

This property is used within the namespace to uniquely identify the class that the

Form is an instance of and, in the case of Visual Basic, is used to access the default

instance of the form

Setting the Title of the Form

The name of the form is the name that is used to refer to the Form class or the default

instance of a form (Visual Basic only) in code, but it is also useful for the form to have

a title that is visible to users This title might be the same as the name of the form but

is more often a description of the form itself, such as Data Entry The title can also be used to convey information to the user, such as “Processing Entries — My Application”

or “Customer Entry — My Application” The title appears in the title bar and on the taskbar

You can change the title of a form by changing the Text property To change the title of

a form at design time, set the Text property of the form in the Property Grid To change the title of a form at run time, set the Text property of the form in code, as shown in

the following code:

' VB

Form1.Text = "Please enter your address"

// C#

Form1.Text = "Please enter your address";

Setting the Border Style of the Form

The border style of a form determines how the border of the form looks and, to a certain

extent, how a form behaves at run time Depending on the setting, the FormBorderStyle

property can control how the border appears, whether a form is resizable by the user at run time, and whether various control boxes appear (although these are also deter­

mined by other form properties) The FormBorderStyle property has seven possible val­

ues, which are explained in Table 1-2
