Let VBE_Extras take away the strain of choosing different colours (as well as the eye-strain) by using the Themes functionality to allow you to switch into "Dark Mode" using the built-in Dark Theme.

This post provides code that you can use to customise the text in message box buttons. You can show the message box with 1, 2 or 3 buttons and get the text of the clicked button back.

Showing a MsgBox dialog to a user is great to inform them of stuff or get input. But it can be a problem if the user isn't paying attention to your application and doesn't notice the dialog. But a dialog with a timeout ... using the Windows API function "MessageBoxTimeout" ... won't wait indefinitely ... it'll wait as long as you want it to wait.
