2.1 Customizing the Properties of the Default-Form using the Properties Window
When you start a new Visual Basic 2015 project, the IDE will display the default form along with the Solution Explorer window and the Properties window on the far right, as shown in Figure 2.1.
Figure 2.1: Initial Visual Basic 2015 IDE
|Text||My First VB2015 Project|
|BackColor||128, 255, 255|
* The value for Backcolor (background color) 128,255,255 is actually the RGB color code for Cyan. Instead of typing the RGB value, you can indeed select a colour from the color drop-down list that comprises three tabs, Custom, Web, and System. Clicking on the drop-down arrow will bring out a color palette or a list of color rectangles where you can select a color, as shown the figures below:
Figure 2.3: Custom Palette
Figure 2.4: Web Colours
Figure 2.5: System Colours
The runtime interface is shown in Figure 2.6. Notice that the title of the form has been changed from Form1 to My First VB2015 Project, the background changed to cyan color and the window cannot be maximized.
2.2 Changing the Properties of the Default-Form at Run-Time
You can also change the properties of the form at run-time by writing the relevant codes. The default form is an object and an instant of the form can be denoted by the name Me. The property of the object can be defined by specifying the object’s name followed by a dot or period:
For example, we can set the background color of the form to cyan using the following code
To achieve the same interface as in Figure 2.6, type in the following code by clicking the form to enter the code window:
Public Class Form1 Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Me.Text = “My First VB2015 Project” Me.BackColor = Color.Cyan Me.MaximizeBox=False Me.MinimizeBox = True End Sub End Class
