Windows服务:方便地启动Oracle服务

    Oracle 9i有多个系统服务必须都启动之后才能正常工作，但逐个启动比较费事，多数学习Oracle但机器又不是太好的朋友也不能容忍每次都自动启动Oracle服务（那样512MB的内存在启动时就所剩无几了），所以通常都是要用了再启动，这里给出了批量启动windows系统服务的一个例子，介绍了操控windows系统服务的技巧：

首先新建一个Windows Application工程，取名为Oracle Starter
粘贴如下代码文件：
Form1.Designer.vb
Partial Public Class Form1
    Inherits System.Windows.Forms.Form     <System.Diagnostics.DebuggerNonUserCode()> _
    Public Sub New()
        MyBase.New()         ''''This call is required by the Windows Form Designer.
        InitializeComponent()     End Sub     ''''Form overrides dispose to clean up the component list.
    <System.Diagnostics.DebuggerNonUserCode()> _
    Protected Overloads Overrides Sub Dispose(ByVal disposing As Boolean)
        If disposing AndAlso components IsNot Nothing Then
            components.Dispose()
        End If
        MyBase.Dispose(disposing)
    End Sub     ''''Required by the Windows Form Designer
    Private components As System.ComponentModel.IContainer     ''''NOTE: The following procedure is required by the Windows Form Designer
    ''''It can be modified using the Windows Form Designer.
    ''''Do not modify it using the code editor.
    <System.Diagnostics.DebuggerStepThrough()> _
    Private Sub InitializeComponent()
        Me.Label1 = New System.Windows.Forms.Label
        Me.ListBox1 = New System.Windows.Forms.ListBox
        Me.Button1 = New System.Windows.Forms.Button
        Me.Button2 = New System.Windows.Forms.Button
        Me.SuspendLayout()
        ''''
        ''''Label1
        ''''
        Me.Label1.AutoSize = True
        Me.Label1.Font = New System.Drawing.Font("Tahoma", 12.0!, System.Drawing.FontStyle.Bold, System.Drawing.GraphicsUnit.Point, CType(0, Byte))
        Me.Label1.Location = New System.Drawing.Point(13, 13)
        Me.Label1.Name = "Label1"
        Me.Label1.Size = New System.Drawing.Size(122, 22)
        Me.Label1.TabIndex = 0
        Me.Label1.Text = "Oracle Starter"
        ''''
        ''''ListBox1
        ''''
        Me.ListBox1.Font = New System.Drawing.Font("Tahoma", 12.0!, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point, CType(0, Byte))
        Me.ListBox1.FormattingEnabled = True
        Me.ListBox1.ItemHeight = 19
        Me.ListBox1.Location = New System.Drawing.Point(13, 75)
        Me.ListBox1.Name = "ListBox1"
        Me.ListBox1.Size = New System.Drawing.Size(436, 175)
        Me.ListBox1.TabIndex = 1
        ''''
        ''''Button1
        ''''
        Me.Button1.Location = New System.Drawing.Point(322, 257)
        Me.Button1.Name = "Button1"
        Me.Button1.Size = New System.Drawing.Size(127, 34)
        Me.Button1.TabIndex = 2
        Me.Button1.Text = "Stop all services"
        ''''
        ''''Button2
        ''''
        Me.Button2.Location = New System.Drawing.Point(188, 258)
        Me.Button2.Name = "Button2"
        Me.Button2.Size = New System.Drawing.Size(127, 34)
        Me.Button2.TabIndex = 3
        Me.Button2.Text = "Start all servies"
        ''''
        ''''Form1
        ''''
        Me.AutoScaleBaseSize = New System.Drawing.Size(6, 14)
        Me.ClientSize = New System.Drawing.Size(461, 304)
        Me.Controls.Add(Me.Button2)
        Me.Controls.Add(Me.Button1)
        Me.Controls.Add(Me.ListBox1)
        Me.Controls.Add(Me.Label1)
        Me.Name = "Form1"
        Me.Text = "Oracle Starter"
        Me.ResumeLayout(False)

总结：
这个实例只是运用了系统服务控制的基本功能，高级功能还不甚了解，对于多线程的运用还不是很明确，望大家指正

改进：
程序在运行时假如焦点离开，用户界面便会锁死，虽然尝试了多线程，仍然不理想，应该还Join()方法有关，多次修正未果，请高手指点，谢谢！
