任务栏通知发光 [英] Taskbar notification glow

问题描述

我有一个 TCP 聊天应用程序.当收到新消息时，我想让任务栏发光，直到用户再次打开表单(以防它没有获得焦点/激活).

I have a TCP Chat application. When a new message arrives, I want to make the taskbar glow until the user opens the form again (in case it wasn't focus/activated).

我的意思的一个例子:http://puu.sh/4z01n.png

我怎样才能让它发光?

谢谢！

如果您仍然不明白我的意思..我提供的图像是当某些东西发光"时出现在任务栏图标上的图像.意思是有通知.这就是我想要达到的目标.

If you still don't understand what I mean.. The image I provided is what appears ON the icon i nthe taskbar when something "glows". Meaning there is a notifcation. That's what I want to acheive.
