ProblemYou want to customize a form's background color but don't want the controls on the form to look out of place. SolutionSample code folder: Chapter 09\BackgroundColor No problem: most controls automatically take on the same background color as their container. DiscussionThe demonstration of this effect is simple. Add the following code to a button's Click event to change the background color to some random selection. Place any controls of interest on the form to see how the changing background affects them: Private Sub ActBackground_Click( _ ByVal sender As System.Object, _ ByVal e As System.EventArgs) _ Handles ActBackground.Click ' ----- Change the background to some random color. Dim redPart As Integer Dim greenPart As Integer Dim bluePart As Integer Dim surpriseColor As New Random redPart = surpriseColor.Next(0, 255) greenPart = surpriseColor.Next(0, 255) bluePart = surpriseColor.Next(0, 255) Me.BackColor = Color.FromArgb(redPart, _ greenPart, bluePart) End Sub As shown in Figure 9-9, the RadioButton, Label, and CheckBox controls all adjust automatically by taking on the same background color as the containing form. The TextBox control's background remains white, by design. Place any other controls you might be using on this form to see how they behave. Figure 9-9. Many controls automatically take on the same background color as their container |
