Visual Basic: MAPI Controls
Specifies the appearance of the To edit control in the Address Book when the Show method is specified with the value argument missing or set to False.
object.AddressLabel [ = value ]
The AddressLabel property syntax has these parts:
|object||An object expression that evaluates to an object in the Applies To list.|
|value||A string expression specifying an address label.|
This property is normally ignored and should contain an empty string to use the default label "To." However, when the AddressEditFieldCount property is set to 1, the user has the option of explicitly specifying another label (providing the number of editing controls required by the recipient set equals 1).
