VB.NET 2008窗体应用技巧
2014-08-20来源:易贤网

打开Visual Studio 2008在文件 (File) 菜单上,单击新建项目 (New Project)。在新建项目 (New Project) 对话框的模板 (Templates) 窗格中,单击 Windows 应用程序(Windows Application)。 单击确定 (OK)

窗体应用技巧一,创建浮动窗体。

创建新工程后,选择Form1窗体,添加 Timer1和Timer2控件。为窗体选择一个好看的背景,当然你也可以使用系统默认的背景。

进入代 码编辑器,输入代码:

Public Class Form1

Inherits  System.Windows.Forms.Form

Private Sub Form1_Load(ByVal sender As  System.Object,

ByVal e As System.EventArgs) Handles MyBase.Load

Dim  pos As Point = New Point(100, 50) '设置窗体初始位置

Me.DesktopLocation =  pos

Timer1.Interval = 10 '设置Timer的值

Timer1.Enabled = True

Timer2.Interval = 10

Timer2.Enabled = False

End Sub

进入Timer1_Tick事件

Private Sub Timer1_Tick(ByVal sender As System.Object,  ByVal e As System.EventArgs)

Handles Timer1.Tick

Dim pos As Point =  New Point(Me.DesktopLocation.X + 2, Me.DesktopLocation.Y + 1)

'窗体 左上方横坐标的timer1加

If pos.X < 600 Or pos.Y < 400 Then

Me.DesktopLocation = pos

Else

Timer1.Enabled = False

Timer2.Enabled =  True

End If

End Sub

进入Timer2_Tick事件

Private Sub  Timer2_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs)

Handles Timer2.Tick

Dim pos As Point = New Point(Me.DesktopLocation.X - 2,  Me.DesktopLocation.Y - 1)

'窗体的左上方横坐标随着timer2减一

If  pos.X > 100 Or pos.Y > 50 Then

Me.DesktopLocation = pos

Else

Timer1.Enabled = True

Timer2.Enabled = False

End If

End  Sub

创建完成后我们来运行程序测试一下,测试成功,程序在屏幕中不断地来回走动了。
