In a Microsoft Access database (.mdb), startup properties are properties of a object. A Database object is a DAO object supplied by the Microsoft Jet database engine, but startup properties are defined by Microsoft Access, so they aren't automatically recognized by the Jet database engine. If a startup property hasn't been set previously, you must create it and add it to the collection of the Database object.

In a Microsoft Access project (.adp), startup properties are properties of a CurrentProject object and like the Database object in an Access database (.mdb), startup properties aren't automatically recognized by the Jet database engine. If a startup property hasn't been set previously, you must create it and add it to the AccessObjectProperties collection of the CurrentProject object.

When you set startup properties from Visual Basic, you should include error-handling code to verify that the property exists in the Properties or AccessObjectProperties collection. For more information about setting properties defined by Microsoft Access, see Set Properties of Data Access Objects in Visual Basic or Set Properties of ActiveX Data Objects in Visual Basic.

The names of the startup properties differ from the text that appears in the Startup dialog box, available by clicking Startup on the Tools menu. The following table provides the name of each startup property as it's used in Visual Basic code.
