VB.NET 2008窗體應用技巧

   打開Visual Studio 2008在文件 (File) 菜單上,單擊新建項目 (New Project)。在新建項目 (New Project) 對話框的模板 (Templates) 窗格中,單擊 Windows 應用程序(Windows Application)。 單擊確定 (OK)

  窗體應用技巧一,創建浮動窗體。

  創建新工程後,選擇Form1窗體,添加 Timer1和Timer2控件。為窗體選擇一個好看的背景,當然你也可以使用系統默認的背景。

  進入代 碼編輯器,輸入代碼:

  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) '設置窗體初始位置

  Me.DesktopLocation =  pos

  Timer1.Interval = 10 '設置Timer的值

  Timer1.Enabled = True

  Timer2.Interval = 10

  Timer2.Enabled = False

  End Sub

  進入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)

  '窗體 左上方橫坐標的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

  進入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)

  '窗體的左上方橫坐標隨著timer2減一

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

  Me.DesktopLocation = pos

  Else

  Timer1.Enabled = True

  Timer2.Enabled = False

  End If

  End  Sub

  創建完成後我們來運行程序測試一下,測試成功,程序在屏幕中不斷地來回走動了。
