屏保程序的本质上就是一个
Win32
窗口应用程序;把编译好一个窗口应用程序之后,把扩展名更改为 scr
,于是你的屏幕保护程序就做好了;
选中修改好的 scr
程序上点击右键,可以看到一个安装
选项,点击之后就安装了;
安装之后会立即看到我们的屏幕保护程序已经运行起来了;
处理屏幕保护程序参数如下
/s 屏幕保护程序开始,或者用户点击了 预览
按钮;/c 用户点击了 设置
按钮;/p 用户选中屏保程序之后,在预览窗格中显示;
1)MainWindow.xaml
代码如下;
<Window x:Class="ScreenSaver.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

<Grid x:Name="MainGrid">

<Rectangle.Fill>
<ImageBrush ImageSource="{Binding .}"/>
</Rectangle.Fill>
</Rectangle>
</DataTemplate>
</drawing:PanningItems.ItemTemplate>
</drawing:PanningItems>
<Grid HorizontalAlignment="Center"
VerticalAlignment="Top"

</Grid.RowDefinitions>
<Grid.Resources>
<Style TargetType="TextBlock">

<Setter Property="Foreground" Value="White"/>
</Style>
</Grid.Resources>
<WrapPanel>
<TextBlock Text="{Binding Hour,RelativeSource={RelativeSource AncestorType=local:MainWindow}}"/>
<TextBlock Text=":" x:Name="PART_TextBlock">
<TextBlock.Triggers>
<EventTrigger RoutedEvent="FrameworkElement.Loaded">
<BeginStoryboard>
<Storyboard>
<DoubleAnimation Duration="00:00:01"

To="0"
Storyboard.TargetName="PART_TextBlock"
Storyboard.TargetProperty="Opacity"
RepeatBehavior="Forever"
FillBehavior="Stop"/>
</Storyboard>
</BeginStoryboard>
</EventTrigger>
</TextBlock.Triggers>
</TextBlock>
<TextBlock Text="{Binding Minute,RelativeSource={RelativeSource AncestorType=local:MainWindow}}"/>
</WrapPanel>
<TextBlock Grid.Row="1" FontSize="45" HorizontalAlignment="Center" Text="{Binding Date,RelativeSource={RelativeSource AncestorType=local:MainWindow}}"/>
</Grid>
</Grid>
</Window>
2) MainWindow.xaml.cs
代码如下;
当屏保启动后需要注意如下 将鼠标设置为不可见 Cursors.None
;将窗体设置为最大化 WindowState.Maximized
;WindowStyle
设置为"None"
;注意监听 鼠标按下
和键盘按键
则退出屏保;
