篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了新建 WinCE7.0 下的 Silverlight 工程相关的知识，希望对你有一定的参考价值。
以下文章以 http://download.csdn.net/detail/91program/7588393 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：
<?xml version="1.0" encoding="utf-8"?> <VisualStudioToolFile Name="XRPack Tool" Version="8.00" > <Rules> <CustomBuildRule Name="XRPack Tool" DisplayName="XRPack Tool" CommandLine=""$(VSInstallDir)VC\VCWizards\WindowsEmbeddedSilverlightTools\XRPack.exe" "/Root=$(ProjectDir)" "/IntermediateFiles=$(OutDir)" "@$(InputPath)"" Outputs="$(InputName)Generated.h $(InputName)Generated.rc2" FileExtensions="*.xrpack" ExecutionDescription="Generating RC2 file." > <Properties> </Properties> </CustomBuildRule> </Rules> </VisualStudioToolFile>
6 将 XRPack.rules 增加到工程文件 SilverlightHelloWorld.vcproj 中，修改了两个地方，修改后的内容如下：
<?xml version="1.0" encoding="gb2312"?> <VisualStudioProject ProjectType="Visual C++" Version="9.00" Name="SilverlightHelloWorld" ProjectGUID="{6DDF8C53-109B-4FC3-90B2-DD270ACA3A2C}" RootNamespace="SilverlightHelloWorld" Keyword="Win32Proj" TargetFrameworkVersion="196613" > <Platforms> <Platform Name="HSW_T9_SDK (ARMv4I)" /> </Platforms> <ToolFiles> <ToolFile RelativePath=".\XRPack.rules" /> </ToolFiles> <Configurations> <Configuration Name="Debug|HSW_T9_SDK (ARMv4I)" OutputDirectory="$(PlatformName)\$(ConfigurationName)" IntermediateDirectory="$(PlatformName)\$(ConfigurationName)" ConfigurationType="1" CharacterSet="1" > <Tool Name="VCPreBuildEventTool" /> <Tool Name="VCCustomBuildTool" /> <Tool Name="XRPack Tool" /> <Tool Name="VCXMLDataGeneratorTool" /> <Tool Name="VCWebServiceProxyGeneratorTool" /> <Tool Name="VCMIDLTool" /> ......
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 <XamlRuntime.h> 3 #include <XRDelegate.h> 4 #include <XRPtr.h> 5 #include <XRCustomControl.h> 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
