{

components.Dispose();

}

base.Dispose(disposing);

}

private void InitializeComponent()

{

this.components = new System.ComponentModel.Container();

this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;

this.Text = "Form1";

}

}

The IContainer member variable and Dispose() methods are little more than infrastructure

used by the Visual Studio designer tools. However, do notice that the InitializeComponent() is pres-

ent and accounted for. Not only is this method invoked by a form’s constructor at runtime, Visual

Studio makes use of this same method at design time to correctly render the UI on the Forms

designer. To illustrate, change the value assigned to the Text property of the window to "My Main

Window". Once you activate the designer, you will find the form’s caption updates accordingly.

As well, when you are making use of the visual design tools (such as the Properties window),

the IDE will update InitializeComponent() automatically. To illustrate this aspect of the Windows

Forms designer tools, ensure the Forms designer is the active window within the IDE and find the

Opacity property listed in the Properties window. Change this value to 0.8 (80%), which will give

your window a slightly transparent look and feel the next time you compile and run your program.

Once you have made this change, examine the implementation of InitializeComponent() once

again:

private void InitializeComponent()

{

this.SuspendLayout();

//

// MainWindow

//

this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);

this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;

this.ClientSize = new System.Drawing.Size(284, 264);

this.Name = "MainWindow";
