BC40008: '<elementname>' is obsolete (Visual Basic Warning)

  • Article

A statement attempts to access a programming element which has been marked with the ObsoleteAttribute attribute and the directive to treat it as a warning.

You can mark any programming element as being no longer in use by applying ObsoleteAttribute to it. If you do this, you can set the attribute's IsError property to either True or False. If you set it to True, the compiler treats an attempt to use the element as an error. If you set it to False, or let it default to False, the compiler issues a warning if there is an attempt to use the element.

By default, this message is a warning, because the IsError property of ObsoleteAttribute is False. For more information about hiding warnings or treating warnings as errors, see Configuring Warnings in Visual Basic.

Error ID: BC40008

To correct this error

  • Ensure that the source-code reference is spelling the element name correctly.
