基本上,我做了一个控制台应用程序,执行一些需要几分钟的任务。我想让它在任务栏中闪现,让我知道它什么时候完成了它的工作。

使用answer that @Zack posted和another one to find the handle of a console app,我想出了这一点,它工作得很好。
class Program
{
[DllImport("user32.dll")]
[return: MarshalAs(UnmanagedType.Bool)]
static extern bool FlashWindowEx(ref FLASHWINFO pwfi);
[StructLayout(LayoutKind.Sequential)]
public struct FLASHWINFO
{
public UInt32 cbSize;
public IntPtr hwnd;
public UInt32 dwFlags;
public UInt32 uCount;
public Int32 dwTimeout;
}
public const UInt32 FLASHW_ALL = 3;
static void Main(string[] args)
{
Console.WriteLine("Flashing NOW");
FlashWindow(Process.GetCurrentProcess().MainWindowHandle);
Console.WriteLine("Press any key to continue");
Console.ReadKey();
}
private static void FlashWindow(IntPtr hWnd)
{
FLASHWINFO fInfo = new FLASHWINFO();
fInfo.cbSize = Convert.ToUInt32(Marshal.SizeOf(fInfo));
fInfo.hwnd = hWnd;
fInfo.dwFlags = FLASHW_ALL;
fInfo.uCount = UInt32.MaxValue;
fInfo.dwTimeout = 0;
FlashWindowEx(ref fInfo);
}
}

结合@Zack评论中链接的问题中的答案和getting the hwnd of a console window using this,我能够让它工作。这是我创建的类:
public static class FlashWindow
{
[DllImport("user32.dll")]
[return: MarshalAs(UnmanagedType.Bool)]
static extern bool FlashWindowEx(ref FLASHWINFO pwfi);
[DllImport("kernel32.dll")]
static extern IntPtr GetConsoleWindow();
[StructLayout(LayoutKind.Sequential)]
public struct FLASHWINFO
{
public UInt32 cbSize;
public IntPtr hwnd;
public UInt32 dwFlags;
public UInt32 uCount;
public UInt32 dwTimeout;
}
public const UInt32 FLASHW_ALL = 3;
public static void Flash()
{
FLASHWINFO fInfo = new FLASHWINFO();
fInfo.cbSize = Convert.ToUInt32(Marshal.SizeOf(fInfo));
fInfo.hwnd = GetConsoleWindow();
fInfo.dwFlags = FLASHW_ALL;
fInfo.uCount = UInt32.MaxValue;
fInfo.dwTimeout = 0;
FlashWindowEx(ref fInfo);
}
}
它不会停止闪烁,直到它被关闭,但这对我的目的并不重要。

我读到它是通过任何直接的方式wasn't possible to get the window handle of a console window的,但实际上在.NET中它似乎相当简单。因此,它与this question基本相同
class Program
{
[DllImport("user32.dll")]
[return: MarshalAs(UnmanagedType.Bool)]
static extern bool FlashWindowEx(ref FLASHWINFO pwfi);
[StructLayout(LayoutKind.Sequential)]
public struct FLASHWINFO
{
public UInt32 cbSize;
public IntPtr hwnd;
public UInt32 dwFlags;
public UInt32 uCount;
public UInt32 dwTimeout;
}
public const UInt32 FLASHW_STOP = 0;
public const UInt32 FLASHW_CAPTION = 1;
public const UInt32 FLASHW_TRAY = 2;
public const UInt32 FLASHW_ALL = 3;
public const UInt32 FLASHW_TIMER = 4;
public const UInt32 FLASHW_TIMERNOFG = 12;
static void Main(string[] args)
{
// Give you a few seconds to alt-tab away :)
Thread.Sleep(2000);
// Flash on the task bar, until the window becomes the foreground window.
// Constants for other behaviors are defined above.
FLASHWINFO fInfo = new FLASHWINFO();
fInfo.cbSize = Convert.ToUInt32(Marshal.SizeOf(fInfo));
fInfo.hwnd = Process.GetCurrentProcess().MainWindowHandle;
fInfo.dwFlags = FLASHW_TRAY | FLASHW_TIMERNOFG;
fInfo.uCount = UInt32.MaxValue;
fInfo.dwTimeout = 0;
FlashWindowEx(ref fInfo);
// Wait for input so the app doesn't finish right away.
Console.ReadLine();
}
}
