What would the code look like that displays a message that will close in 5 seconds?

I'm interested in Win32 functions, not the capabilities of programming languages ​​(C#, C++, etc.).

    There is a Windows API function that will create a self-closing message box based on a timer - WTSSendMessageA function. Refer to the function's Timeout argument. You can obtain the session id of your own session by calling the ProcessIdToSessionId function.

    If you are willing to write some code a timed message box can also be implemented using the TaskDialogIndirect function to take advantage of its built-in timer and callback feature.

    
    TDF_CALLBACK_TIMER
    
    	Indicates that the task dialog's callback is to be called approximately every 200 milliseconds.
