Our program calls InternetCheckConnection every 2 seconds to test whether the program is connected to our server. We have around 4000 clients running our program.

I want to pop up a window to show that a program is busy with a particular time consuming task. But I don't want any buttons on it. I just want to pop it up, do the task, then remove it.
