如何使 WPF 視窗在工作列上閃爍？

在某個特定時刻，我的 WPF 應用程序需要使用者關注。我知道可以使 Windows 7 工作列圖示以黃色閃爍。

到目前為止我嘗試過：

• Window.Activate嘗試將視窗置於前台並啟動它。
• Window.Focus嘗試將焦點設置到此元素。

有什麼建議？

這是一種可能的解決方案：http ://www.jarloo.com/flashing-a-wpf-window/

在程式碼範例中，為 Window 類創建了兩個擴展方法：FlashWindow 和 StopFlashingWindow：

private const UInt32 FLASHW_STOP = 0; //Stop flashing. The system restores the window to its original state.        private const UInt32 FLASHW_CAPTION = 1; //Flash the window caption.        
private const UInt32 FLASHW_TRAY = 2; //Flash the taskbar button.        
private const UInt32 FLASHW_ALL = 3; //Flash both the window caption and taskbar button.        
private const UInt32 FLASHW_TIMER = 4; //Flash continuously, until the FLASHW_STOP flag is set.        
private const UInt32 FLASHW_TIMERNOFG = 12; //Flash continuously until the window comes to the foreground.  


[StructLayout(LayoutKind.Sequential)]        
private struct FLASHWINFO        
{            
   public UInt32 cbSize; //The size of the structure in bytes.            
   public IntPtr hwnd; //A Handle to the Window to be Flashed. The window can be either opened or minimized.


   public UInt32 dwFlags; //The Flash Status.            
   public UInt32 uCount; // number of times to flash the window            
   public UInt32 dwTimeout; //The rate at which the Window is to be flashed, in milliseconds. If Zero, the function uses the default cursor blink rate.        
}         

[DllImport("user32.dll")]        
[return: MarshalAs(UnmanagedType.Bool)]        
private static extern bool FlashWindowEx(ref FLASHWINFO pwfi);         



public static void FlashWindow(this Window win, UInt32 count = UInt32.MaxValue)        
{            
   //Don't flash if the window is active            
   if (win.IsActive) return;             
   WindowInteropHelper h = new WindowInteropHelper(win);             
   FLASHWINFO info = new FLASHWINFO 
   {                                        
       hwnd = h.Handle,                                        
       dwFlags = FLASHW_ALL | FLASHW_TIMER,                                        
       uCount = count,                                        
       dwTimeout = 0                                    
   };             

   info.cbSize = Convert.ToUInt32(Marshal.SizeOf(info));            
   FlashWindowEx(ref info);        
} 

public static void StopFlashingWindow(this Window win)        
{            
   WindowInteropHelper h = new WindowInteropHelper(win);             
   FLASHWINFO info = new FLASHWINFO();            
   info.hwnd = h.Handle;            
   info.cbSize = Convert.ToUInt32(Marshal.SizeOf(info));            
   info.dwFlags = FLASHW_STOP;            
   info.uCount = UInt32.MaxValue;            
   info.dwTimeout = 0;             
   FlashWindowEx(ref info);        
}

很有趣的場景。我原以為這會很簡單。如果我不得不做類似的事情，我會為這個問題添加書籤:)
