This article mainly introduces how to use VB.NET to write pallet procedures, the article is very detailed, has a certain reference value, interested friends must read it!
The design and running environment of this program
(1) Windows 2000 Service
(2) Net Framework SDK official version
The programming process of VB.NET static pallet program
The so-called VB.NET static tray program refers to the tray program in which the icon in the system tray area is at rest after the program runs. On the contrary, the dynamic tray program refers to a kind of tray program that animates the icon in the system tray area. Let's take a look at how VB.NET implements the static tray program.
.net FrameWork SDK provides a component for writing pallet programs: the NotifyIcon component. The NotifyIcon component is a WinForm component located in the namespace "System.Windows.Forms". In the VB.NET program, just create an instance of the NotifyIcon component and assign a value to the "Icon" property of the NotifyIcon instance, and such a simple pallet program is completed. Here is the code (Form1.vb) for this simple pallet program:
Public Class Form1
Inherits System.Windows.Forms.Form
# Region Code generated by the Windows forms designer
Public Sub New ()
MyBase.New ()
'This call is required by the Windows forms designer.
InitializeComponent ()
'add any initialization after the InitializeComponent () call
End Sub
'form rewrite disposal to clean up the list of components.
Protected Overloads Overrides Sub Dispose
(ByVal disposing As Boolean)
If disposing Then
If Not (components Is Nothing) Then
Components.Dispose ()
End If
End If
MyBase.Dispose (disposing)
End Sub
'required for the Windows forms designer
Private components As System.ComponentModel.IContainer
'Note: the following procedures are required for the Windows forms designer
'you can modify this process using the Windows forms designer.
'don 't use the code editor to modify it.
Friend WithEvents NotifyIcon1 As System.Windows.Forms.NotifyIcon
'create an instance of NotifyIcon
Friend TrayIcon = New Icon ("Tray.ico")
'create an instance of Icon
Private Sub InitializeComponent ()
Me.components = New System.ComponentModel.Container ()
Me.NotifyIcon1 = New System.Windows.Forms.NotifyIcon
(Me.components)
Me.NotifyIcon1.Text = "NotifyIcon1"
Me.NotifyIcon1.Visible = True
'assign a value to the Icon attribute of the NotifyIcon instance to complete the simple pallet program
Me.NotifyIcon1.Icon = TrayIcon
Me.AutoScaleBaseSize = New System.Drawing.Size (6,14)
Me.ClientSize = New System.Drawing.Size (292,273)
Me.Name = "Form1"
Me.Text = "Form1"
End Sub
# End Region
End Class
'start the program
Module Module1
Sub Main ()
Application.Run (new Form1 ())
End sub
End Module
