Are DialogBox messages sent to a custom message loop?

I have an application that currently has a message loop. If I were to create a modal dialog box with the DialogBox method would the current message loop receive messages from the dialog as well or would they be withheld by the runtime?

DialogBox creates its own message loop so your message loop will not run. From the documentation:

The function displays the dialog box (regardless of whether the template specifies the WS_VISIBLE style), disables the owner window, and starts its own message loop to retrieve and dispatch messages for the dialog box.

Your existing message loop will not receive the messages for the dialog box. All messages for the dialog would be received by the DLGPROC method that you're passing as the last parameter to the DialogBox function.
