Simple way to make a timeout message box

[Gyannea]

Is there a simple way to display a message box that just kills itself after a certain amount of time (not using MFC)? It would also be nice if the message box were modeless.

THe only reason I am doing this is that windows demands a 2-second wait for the serial port handle to be released (on some machines it happens faster than that, but 2 seconds is in the docs so to be safe one better do the wait). 2 seconds is a long enouhg time to be irritating so I'd like to inform the user without the user having to do anything.

Probably have to create a modeless dialog box or class window with a static window containing the message with a self destructing timer, right?

You may use SetTimer to create a timer with an elapse of 1000 milliseconds. You can specify that your modeless dialog will receive WM_TIMER if the second elapses. Then you may count the seconds, and close the dialog after 30 seconds elapse.

But you have to design this messagebox on your own, because I do not think that you can display the windows messagebox modeless.

That's what I was afraid of. Have to make my own window, callback, timer, and in the callback a handler for the timer to destroy the window. I have an owner draw message box which I guess I might as well modify to handle this type of thing. No easy way out!

I can't find any way to create a modeless messagebox.

Thanks NoHero,

I'll take a look at their approach....but I think I will ditch the thread.

This is like 21 years later, but I finally came across another person's API solution - works like a dream:
