If the dialog box does not have a default command button, then the idItem parameter is set to IDOK by default. If a dialog box or one of its controls currently has the input focus, then pressing the ENTER key causes Windows to send a WM_COMMAND message with the idItem (wParam) parameter set to the ID of the default command button. This method is based on the following behavior of dialog boxes (Dialog Manager) and focus handling in Windows.
