VB.NET窗體應用技巧百寶箱
很喜歡用VB.NET編程序,在網上也收集了很多相關的材料,在這里我就VB.NET窗體應用總結了一個技巧,下面我們來一起看看吧。
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)
VB.NET窗體應用技巧一,創建浮動窗體。
創建新工程后,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.LoadDim pos As Point = New Point(100, 50)
- '設置窗體初始位置Me.DesktopLocation = posTimer1.Interval = 10
- '設置Timer的值Timer1.Enabled = TrueTimer2.Interval = 10Timer2.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.TickDim 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 ThenMe.DesktopLocation = posElseTimer1.Enabled = FalseTimer2.Enabled = TrueEnd 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.TickDim 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
- ThenMe.DesktopLocation = posElseTimer1.Enabled = TrueTimer2.Enabled = False
- End If
- End Sub
創建完成后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。
VB.NET窗體應用技巧二,創建透明的窗體。
創建新工程后,選擇Form1窗體,添加Label1、TrackBar1、Timer1控件。為了突出效果為窗體選擇一個好看的背景。
相關的屬性設置如下:
TrackBar1 Value屬性:
TickFrequency: 屬性:
Maximum屬性: 100
10
100
Label1 Text屬性: 選擇窗體的透明度:
Timer1 Interval屬性: 100
進入代碼編輯器,輸入代碼:
首先進行聲明:
- Public Class Form1
- Inherits System.Windows.Forms.FormDim tps
- As IntegerDim bol As Boolean
進入TrackBar1_Scroll事件
- Private Sub TrackBar1_Scroll(ByVal sender As Object, ByVal e As System.EventArgs)
- Handles TrackBar1TrackBar1.ScrollMe.Opacity = TrackBar1.Value / 100Label1.Text = "窗體透明度:" & CStr(Me.Opacity * 100) & "%"
- End Sub
進入Timer1_Tick事件
- Private Sub Timer1_Tick(ByVal sender As Object, ByVal e As System.EventArgs) Handles Timer1.TickIf bol = False Thentps
= tps + 1Me.Opacity = tps / 100If Me.Opacity >= 1 ThenTimer1.Enabled = Falsebol = TrueEnd IfElsetps = tps - 1Me.Opacity =
tps / 100If Me.Opacity <= 0 ThenTimer1.Enabled = Falsebol = FalseEnd- If End
- If End
- Sub
進入Form1_Load事件
- Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.LoadTimer1.Enabled = TrueEnd Sub
進入Form1_Closing事件
- Private Sub Form1_Closing(ByVal sender
- As Object, ByVal e As System.ComponentModel.CancelEventArgs)
- Handles MyBase.ClosingTimer1.Enabled = TrueIf MsgBox("你確實要關閉窗體嗎?", MsgBoxStyle.OkCancel) = MsgBoxResult.Ok
- Thene.Cancel = FalseElseTimer1.Enabled = FalseMe.Opacity = 1tps = 100bol = Truee.Cancel = True
- End If
- End Sub
創建完成后我們來運行程序測試一下,測試成功,VB.NET窗體應用是不是變得透明了,通過調節滾動條我們甚至可以使得窗體消失達到完全隱形的目的。這是不是很神奇呢?
