Option Private Statement

Microsoft Visual Basic Constants

Option Private Statement

       

When used in host applications that allow references across multiple projects, Option Private Module prevents a module’s contents from being referenced outside its project. In host applications that don’t permit such references, for example, standalone versions of Visual Basic, Option Private has no effect.

Syntax

Option Private Module

Remarks

If used, the Option Private statement must appear at module level, before any procedures.

When a module contains Option Private Module, the public parts, for example, variables, objects, and user-defined types declared at module level, are still available within the project containing the module, but they are not available to other applications or projects.

Note   Option Private is only useful for host applications that support simultaneous loading of multiple projects and permit references between the loaded projects. For example, Microsoft Excel permits loading of multiple projects and Option Private Module can be used to restrict cross-project visibility. Although Visual Basic permits loading of multiple projects, references between projects are never permitted in Visual Basic.
