Microsoft Access defines a number of properties on data access objects. These properties are not automatically recognized by the Microsoft Jet database engine. In order to set or return values for a Microsoft Access–defined property in Visual Basic, you must specifically add the property to the Properties collection of the object to which it applies. You can do this by using the CreateProperty method to create the property and then appending it to the Properties collection.
For example, Microsoft Access defines the Description property of a TableDef object. If this property hasn't already been set from table Design view, you must use the CreateProperty method to create the property and then append it to the Properties collection in order to set the property from Visual Basic.
A Microsoft Access–defined property is automatically added to the Properties collection when it is first set from the Microsoft Access window. If the property has already been set in this way, then you don't need to add it to the Properties collection.
When you write code to set a Microsoft Access–defined property, you should include an error-handling routine that creates a Property object representing that property and appends it to the Properties collection if it does not already exist in the collection.
When you refer to a Microsoft Access–defined property in Visual Basic, you must explicitly refer to the Properties collection. For example, you would refer to the AppTitle property in the following manner, once it exists within the Properties collection of a Database object representing the current database.
Dim dbs As Database
Set dbs = CurrentDb
dbs.Properties!AppTitle = "Northwind Traders"Note You need to create and append only the Microsoft Access properties that apply to DAO objects. You can set other Microsoft Access properties in Visual Basic by using the standard object.property syntax.
