ActiveX alert message
 

Hi,
I'm using the calendar ActiveX control msacal70.ocx on a user form. When I
open the app the alert message pop-up: "This app is about to initialize
ActiveX controls ..."
I tried Application.DisplayAlerts = False in the workbook and the form
opening/initializing events but it doesn't help.
Is there any way to get rid of this message?

Thanks
