本文共 23995 字，大约阅读时间需要 79 分钟。

以下文章以中的工程为基础，这也是我写此文章时一步一步建立的 Silverlight 工程。

1 使用 Microsoft Expression Blend 3 创建一个 Silverlight for Windows Embedded Application 工程，放一个按键控件在窗体上，命名按键然后保存。由于 Microsoft Expression Blend 3 现在只支持生成 C# 的代码，对我们没有什么用，所以我们只用其中的 XAML 文件。

2 VS2008 新建：智能设备->Win32 智能设备项目，选拔一个支持 Silverlight 的SDK。

3 文件 SilverlightHelloWorld.cpp 中，只保留如下代码，其它删除：

1 // SilverlightHelloWorld.cpp : 定义应用程序的入口点。   2 //   3    4    5 #include "stdafx.h"   6 #include "SilverlightHelloWorld.h"   7    8    9   10   11 int WINAPI WinMain(HINSTANCE hInstance,  12                    HINSTANCE hPrevInstance,  13                    LPTSTR    lpCmdLine,  14                    int       nCmdShow)  15 {  16   return 0;  17 }

4 新增加 4 个空文件，内容后面补，分别是：

App.cpp  App.h  MainPage.cpp  MainPage.h

5 增加文件 XRPack.rules，文件的内容如下：

6 将 XRPack.rules 增加到工程文件 SilverlightHelloWorld.vcproj 中，修改了两个地方，修改后的内容如下：

7 新增文件 SilverlightHelloWorld.xrpack，其内容如下：

# This file is used to generate the rc2 file and baml resources      # Uncomment /C to force xrpack to perform a clean build every time  # /C      # Verbosity can be a value between 1 and 10  /Verbosity=3      /NoResourceCompile  "/TargetRC=WinEmbeddedHelloWorldGenerated.rc2"  "/TargetHeader=WinEmbeddedHelloWorldGenerated.h"  "/Project=..\WinEmbeddedHelloWorld\WinEmbeddedHelloWorld.csproj"

8 修改 stdafx.h ，增加以下内容：

1 // Xaml Runtime Header Files   2 #include 
     
         3 #include 
      
          4 #include 
       
           5 #include 
        
            6    7    8 // IUnknown   9 extern "C" const GUID __declspec(selectany)IID_IUnknown = __uuidof(IUnknown);  10   11   12 // Resource type for XAML files  13 #define RT_XAML L"XAML"  14   15   16 // Application headers  17 #include "App.h"  18 #include "resource.h"

9 将 SilverlightHelloWorld.xrpack 文件增加到工程中

这样才能自动生成 WinEmbeddedHelloWorldGenerated.rc2 和 WinEmbeddedHelloWorldGenerated.h 文件

10 WinMain() 函数的实现代码如下：

int WINAPI WinMain(HINSTANCE hInstance,HINSTANCE hPrevInstance,LPTSTR lpCmdLine,int nCmdShow)

{

App AppInstance;

HRESULT hr = AppInstance.Initialize(hInstance);

if(SUCCEEDED(hr))

{

hr = AppInstance.Run();

}

return AppInstance.GetWinMainResultCode();

}

11 编译，是可以成功的，但还需要根据 XAML 文件的内容来修改 MailPage.cpp 和 MailPage.h。

MailPage.h

13 编译、运行，失败了！程序没有加载起来。一般来说，没有加载成功是因为 XMAL 解析失败，或资源没有加载成功。需要进一步分析是什么具体的原因？

调试代码发现，如下函数在加载资源时报错: hr = -2147023082 {找不到映像文件中指定的资源名。}

1 HRESULT App::InitializeComponent()  2 {  3     XRXamlSource appXaml(GetHInstance(), IDR_SILVERLIGHTCLOCK_APP);  4     HRESULT hr = m_pApplication->LoadResourceDictionary(&appXaml,NULL);  5     return hr;  6 } // InitializeComponent

解决方法：

将资源文件 SilverlightHelloWorld.rc 中的 SilverlightHelloWorld.rc2 替换成 SilverlightHelloGenerated.rc2，共两处。

14 编译、运行，可以看到想要的界面。点击按键，会弹出一个对话框。

OK，到此新建 WinCE 下 Silverlight 工程的整个过程算是结束了，是不是有些复杂？

呵呵...，个人的感觉也是，挺复杂的。
