View Applets in WPF

I have been working in Shenzhen for a month. I used to work in winform, but now I am working in WPF. I work overtime every day until AM, tired of me. There is also a process to learn new technologies, from the basic syntax and
Interface layout. This is a small piece of software I build.

Appreciation

On the basis of the original, a leaf fluttering effect is added.

The main code is as follows:

 1 <Canvas.Triggers> 2                 <EventTrigger RoutedEvent="FrameworkElement.Loaded"> 3                     <BeginStoryboard> 4                         <Storyboard Storyboard.TargetName="img1" Storyboard.TargetProperty="(Canvas.Left)"> 5                             <DoubleAnimation From="0" To="514" Duration="0:0:20" RepeatBehavior="23:59:59" AutoReverse="True"/> 6                         </Storyboard> 7                     </BeginStoryboard> 8                     <BeginStoryboard Storyboard="{StaticResource StoryboardLeaf}"/> 9                 </EventTrigger>10             </Canvas.Triggers>

Float leaves

1 This. showintaskbar = false; // whether it is displayed on the taskbar

Display on the taskbar

1 timer = new dispatchertimer (); // Class 2 timer that is processed by time interval. interval = timespan. parse ("00:00:01"); // time interval of the time scale. The default value is timer. isenabled = true; 4 timer. tick + = new eventhandler (timer_tick); // dispatchertimer. occurs when the tick time interval is exceeded.

Set the interval

1 bitmapimage dayornight = new bitmapimage (); // create an image 2 dayornight. begininit (); 3 string uri = "pack: // application:,/wpftimezoneexample; component/images/"; 4 int nowhour = int32.parse (datetime. now. tostring ("hh"); 5 If (nowhour> = 6 & nowhour <= 18) 6 {7 URI ++ = "sun2.png"; 8 daymark. width = 105; 9 daymark. height = 53; 10} 11 else12 {13 URI + = "moon.png"; 14 daymark. width = 50; 15 daymark. height = 50; 16} 17 dayornight. urisource = new uri (URI); // set source 18 dayornight. endinit (); 19 daymark. source = dayornight;

Code to create an image

Interval execution

1 private void grid_previewmouseleftbuttondown (Object sender, mousebuttoneventargs E) 2 {3 this. dragmove (); // drag 4}

Program drag

When the mouse is placed, the sun/moon changes

1 private void daymark_mouseenter (Object sender, mouseeventargs E) 2 {3 translatetransform trans = new translatetransform (); // transformgroup4 daymark. rendertransform = trans; // set the translation object to 5 doubleanimation animation = new doubleanimation (15, timespan. fromseconds (1); // 15 is the target value, and the last parameter is animation duration 6 animation. autoreverse = true; // whether to play 7 TRANS in reverse order. beginanimation (translatetransform. yproperty, animation); // translatet Ransform. yproperty: The property that moves along X and Y.
