当新消息到达时，如何让任务栏像 Messenger 一样使我的应用程序闪烁? [英] How to make the taskbar blink my application like Messenger does when a new message arrive?

问题描述

在 .NET 或本机 DLL 中是否有 API 调用可用于在与我聊天的人做出响应时创建与 Windows Live Messenger 类似的行为?

Is there an API call in .NET or a native DLL that I can use to create similar behaviour as Windows Live Messenger when a response comes from someone I chat with?

推荐答案

FlashWindowEx 是要走的路.请参阅此处了解 MSDN 文档

FlashWindowEx is the way to go. See here for MSDN documentation

[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_ALL = 3; 

调用函数:

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);

这是从 Pinvoke.net
