The Panel Class The PictureBox Class
5.1.13 The Panel Class
A panel is a container that can hold other controls. Panels are typically used to group related controls in a form. Like the PictureBox class, the Panel class has a BorderStyle property that defines the panels border and can take as its value any member of the BorderStyle enumeration: None the default value, FixedSingle , and Fixed3D . You can add controls to a Panel object using the Add method or the AddRange method of the Control.ControlCollection class. The following code adds a button and a text box to a Panel control called panel1: 199 Dim panel1 As Panel = New Panel Dim textBox1 As TextBox = New TextBox Dim WithEvents button1 As Button button1 = New Button button1 button1.Location = New System.Drawing.Point104, 72 button1.Name = button1 button1.Size = New System.Drawing.Size64, 48 button1.TabIndex = 0 button1.Text = Button1 textBox1 textBox1.Location = New System.Drawing.Point128, 48 textBox1.Name = textBox1 textBox1.TabIndex = 1 panel1.Controls.AddRangeNew Control {textBox1, button1} panel1.Location = New System.Drawing.Point24, 24 panel1.Name = Panel1 panel1.Size = New System.Drawing.Size336, 216 Me.Controls.Addpanel15.1.14 The PictureBox Class
The PictureBox class represents a control to display an image. Loading an image into this control is achieved by assigning a System.Drawing.Bitmap object to its Image property, as the following code does: Dim pictureBox1 As PictureBox = New PictureBox pictureBox1.Image = New System.Drawing.Bitmapc:\tv.bmp pictureBox1.Location = New System.Drawing.Point72, 64 pictureBox1.Size = New System.Drawing.Size144, 128 Me.Controls.AddpictureBox1 In addition, the PictureBox class has the BorderStyle and SizeMode properties. The BorderStyle property determines the PictureBox objects border and can take as its value any member of the BorderStyle enumeration: None the default value, FixedSingle , and Fixed3D . The SizeMode property determines how the image assigned to the Image property is displayed. The SizeMode property can take any of the members of the PictureBoxSizeMode enumeration: AutoSize , CenterImage , Normal the default value, and StretchImage .5.1.15 The RadioButton Class
