The InputMask property can contain up to three sections separated by semicolons (;).
Section Description
First Specifies the input mask itself; for example, !(999) 999-9999. For a list of characters you can use to define the input mask, see the following table.
Second Specifies whether Microsoft Access stores the literal display characters in the table when you enter data. If you use 0 for this section, all literal display characters (for example, the parentheses in a phone number input mask) are stored with the value; if you enter 1 or leave this section blank, only characters typed into the control are stored.
Third Specifies the character that Microsoft Access displays for the space where you should type a character in the input mask. For this section, you can use any character; to display an empty string, use a space enclosed in quotation marks (" ").
