VC++ 2008 Express创建WPF工程的方法
很显然, 如果不是MicroSoft对Visual C++的定位有变化, 就是MicroSoft在弱化C++在Visual Studio中的地位.
可以看到, Visual C++ 2008 Express Edition (简称VC2008 EE)中没有WPF Project的工程模板, MicroSoft也没有对Visual C++ 2008 Express提供编译XAML 和 WPF Designer的支持, 但是不代表我们不能使用C++ 开发WPF工程, 因为VC同样可以访问那些必要的组件和方法.
感谢MS MVP Void Nish 在这里提供的资料, 我们来建立一个WPF工程 for VC2008EE:

• 打开VC2008 EE, 新建一个C++项目, 项目类型选择: CLR Empty Project, 输入项目名称,比如 “WPFProject”
• 然后打开工程选项, Common Properties->References. 添加如下引用:
  PresentationCore
  PresentationFramework
  System
  System.Xml
  UIAutomationProvider
  UIAutomationTypes
  WindowsBase
• 给这个项目新建一个C++源文件, 如main.cpp, 输入如下内容
  

  namespace WPFProject{ using namespace System; using namespace System::IO; using namespace System::Windows; using namespace System::Windows::Media::Imaging; using namespace System::Windows::Media::Animation; using namespace System::Windows::Markup; using namespace System::Windows::Interop; using namespace System::Windows::Controls; using namespace System::Xml; ref struct EventHelper { //Quit Application static void OnButtonQuit_Click(Object^ sender, RoutedEventArgs^ e) { Window^ mainWnd = Windows::Application::Current->MainWindow; mainWnd->Close(); } //Load .jpg file to image //and begin a Stroyboard static void OnButtonAction1_Click(Object^ sender, RoutedEventArgs^ e) { Window^ mainWnd = Windows::Application::Current->MainWindow; Image^ img = (Image^)mainWnd->FindName(“imageTest”); Uri^ uri = (Uri^)gcnew Uri(IO::Directory::GetCurrentDirectory()+ “\\disp.jpg”); BitmapImage ^bmp = gcnew BitmapImage(uri); img->Source = bmp; Storyboard^ myStory = (Storyboard^)Windows::Application::Current->Resources["myStory"]; myStory->Begin(mainWnd, true); } //resume storyboard static void OnButtonAction2_Click(Object^ sender, RoutedEventArgs^ e) { Window^ mainWnd = Windows::Application::Current->MainWindow; Storyboard^ myStory = (Storyboard^)Windows::Application::Current->Resources["myStory"]; myStory->Resume(mainWnd); } //pause storyboard static void OnButtonAction3_Click(Object^ sender, RoutedEventArgs^ e) { Window^ mainWnd = Windows::Application::Current->MainWindow; Storyboard^ myStory = (Storyboard^)Windows::Application::Current->Resources["myStory"]; myStory->Pause(mainWnd); } }; int LoadWPFWindow() { //load Application Resource FileStream^ resStream = File::OpenRead(“App1.xaml”); if(resStream == nullptr) return 0; Application ^app = (Application^)XamlReader::Load(resStream); resStream->Close(); //load Window FileStream^ pStream = File::OpenRead(“Window1.xaml”); if(pStream == nullptr) return 0; Window^ wpfWindow = (Window^)XamlReader::Load(pStream); pStream->Close(); //FindName will find the element with the specified identifier //And raise event handler Button^ btn = (Button^)wpfWindow->FindName(“buttonQuit”); btn->Click += gcnew RoutedEventHandler(&EventHelper::OnButtonQuit_Click); btn = (Button^)wpfWindow->FindName(“buttonAction1″); btn->Click += gcnew RoutedEventHandler(&EventHelper::OnButtonAction1_Click); btn = (Button^)wpfWindow->FindName(“buttonAction2″); btn->Click += gcnew RoutedEventHandler(&EventHelper::OnButtonAction2_Click); btn = (Button^)wpfWindow->FindName(“buttonAction3″); btn->Click += gcnew RoutedEventHandler(&EventHelper::OnButtonAction3_Click); return app->Run(wpfWindow); } [STAThreadAttribute] int WPFMain() { LoadWPFWindow(); return 0; } }

• 新建两个xaml文件, 如Window1.xaml和App1.xaml,分别输入以下内容:
  Window1.xaml, 定义了静态的窗口元素:

  <Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="WPF Test" Height="400" Width="400" > <Grid > <DockPanel Margin="0,0,0,0" Name="dockPanelMain" Background="Ivory" VerticalAlignment="Top" LastChildFill="True"> <TextBlock Height="21" Name="textBlockTitle" DockPanel.Dock="Top" > WPF Project Test </TextBlock> <StackPanel Background="LightGoldenrodYellow" DockPanel.Dock ="Left" Width="120" Margin="5" Height="200" > <Expander IsExpanded ="True" Header="Action Menu"> <Border Margin ="5" Padding ="10" Background ="Ivory" BorderBrush ="DimGray" BorderThickness ="1"> <StackPanel> <Button x:Name="buttonAction1">Action 1(Load)</Button> <Button x:Name="buttonAction2">Action 2(Resume)</Button> <Button x:Name="buttonAction3">Action 3(Pause)</Button> <Line Margin="3" Fill="Ivory"></Line> <Button x:Name="buttonQuit">Quit</Button> </StackPanel> </Border> </Expander> </StackPanel> <Canvas DockPanel.Dock="Right" > <Image Canvas.Left=“30″ Canvas.Top=“50″ Height=“150″ x:Name=“imageTest” Stretch=“Fill” Width=“150″ > <Image.RenderTransform> <ScaleTransform ScaleX=“1″ ScaleY=“0″ CenterY=“75″ CenterX=“75″ x:Name=“transf”/> </Image.RenderTransform> </Image> </Canvas> </DockPanel> </Grid> </Window>

  App1.xaml, 我这里是包含了一些资源, 样式表和故事板:

  <Application xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" > <Application.Resources> <Style TargetType ="{x:Type Button}"> <Setter Property ="Background" Value ="Yellow"/> </Style> <Storyboard RepeatBehavior=“Forever” AutoReverse=“True” x:Name=“myStory1″ x:Key=“myStory”> <DoubleAnimation Storyboard.TargetName=“transf” Storyboard.TargetProperty=“ScaleY” From=“0″ To=“1″ Duration=“0:0:1″ /> </Storyboard> </Application.Resources> </Application>

• 还是工程选项, 在linker->advance->Entery Point设置成我们的启动函数WPFMain; Linker->System->Sub System设置成Windows (/SUBSYSTEM:WINDOWS).




别忘了入口函数WPFMain()前的[STAThreadAttribute]标记, 否则会在解析XAML流是抛出一个XamlParseException异常.
(btw, 我不晓得怎么在.Net下俘获这样的异常, try {}catch (XamlParseException ^e) {} 是俘获不到的. 晕一个.)

然后就OK了, 运行.
