How to use a mask in excel vba? : I got as a required task to fix a date input in a vba form.

In the form, there is a textbox. I'm required to have for the user the date entered as

MM/DD/YYYY

My task is to use an input mask, this is what I'm required, not allowed to do something as validating date after or using a calendar.

So far I was able to use the 2 methods mentionned above (forcing the format after using `ISDATE`).

However, it's has now been made clear it HAS to be a mask so keys are filtered on entry, with the mask being visible when entering the date:

__/__/____

Is there a way to do it? I can only find tutorial for mask on access vba.
