通过标准的.NET Windows Application我们只能建立一个使用Comctl32.dll Version 5的应用程序。即便我们的程序运行在Windows XP系统下，外观仍旧沿用了Windows 2000。实际上通过简单的设置，就可以让我们的程序在Windows XP下面显示为新的程序外观。

首先我们建立自己的Windows Application，然后拖拽一个按钮（Button），一个进度条（ProgressBar），一个组合框（ComboBox），一个单选框（RadioButton）和一个复选框（CheckBox）。这些控件是在Windows XP下面有其特殊的显示效果。我们把其中的FlatStyle属性设置为System。这个操作表示我们这些控件的平面外观样式使用操作系统的默认值。

之后我们在我们应用程序的文件目录建立一个manifest文件。假如我们的应用程序AssemblyName是myapp，那么这个文件名就是myapp.exe.manifest。编辑这个文件的内容。

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">

<assemblyIdentity

   version="1.0.0.0"

   processorArchitecture="X86"

   name="Microsoft.Winweb.[AssemblyName]"

   type="win32"

/>

<description>.NET control deployment tool</description>

<dependency>

   <dependentAssembly>

     <assemblyIdentity

       type="win32"

       name="Microsoft.Windows.Common-Controls"

       version="6.0.0.0"

       processorArchitecture="X86"

       publicKeyToken="6595b64144ccf1df"

       language="*"

     />

   </dependentAssembly>

</dependency>

</assembly>

其中name="Microsoft.Winweb.[AssemblyName]"的部分写入自己程序的AssemblyName。比如这个程序我们就写成name="Microsoft.Winweb.myapp"。保持执行文件和这个manifest文件在同一目录下。这样，如果我们的程序在Windows XP系统下面运行，那么就会自动显示Windows XP的效果。

程序代码如下：

Public Class Form1

    Inherits System.Windows.Forms.Form

#Region " Windows Form Designer generated code "

    Public Sub New()

        MyBase.New()

        'This call is required by the Windows Form Designer.

        InitializeComponent()

        'Add any initialization after the InitializeComponent() call

    End Sub

    'Form overrides dispose to clean up the component list.

    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 by the Windows Form Designer

    Private components As System.ComponentModel.IContainer
