HideModuleNameAttribute Class

The HideModuleNameAttribute attribute, when applied to a module, allows the module members to be accessed using only the qualification needed for the module.

System.Object
  System.Attribute
    Microsoft.VisualBasic.HideModuleNameAttribute

Namespace:  Microsoft.VisualBasic
Assembly:  Microsoft.VisualBasic (in Microsoft.VisualBasic.dll)

[<Sealed>]
[<AttributeUsageAttribute(AttributeTargets.Class, AllowMultiple = false, Inherited = false)>]
type HideModuleNameAttribute =  
    class 
        inherit Attribute 
    end

The HideModuleNameAttribute type exposes the following members.

  NameDescription

  NameDescription
Public propertyTypeIdWhen implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute.)

Public methodSupported in .NET for Windows Store appsGetHashCodeReturns the hash code for this instance. (Inherited from Attribute.)
Public methodSupported in .NET for Windows Store appsGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodIsDefaultAttributeWhen overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute.)
Public methodMatchWhen overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.)
Public methodSupported in .NET for Windows Store appsToStringReturns a string that represents the current object. (Inherited from Object.)

  NameDescription
Explicit interface implemetationPrivate method_Attribute.GetIDsOfNamesMaps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.)
Explicit interface implemetationPrivate method_Attribute.GetTypeInfoRetrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.)
Explicit interface implemetationPrivate method_Attribute.GetTypeInfoCountRetrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.)
Explicit interface implemetationPrivate method_Attribute.InvokeProvides access to properties and methods exposed by an object. (Inherited from Attribute.)

This attribute is useful for exposing module members without showing the module itself. When using IntelliSense in the Visual Studio Integrated Development Environment (IDE) for Visual Basic, the module does not show in the statement completion list. Instead, IntelliSense shows the module members.

Even when the module name is hidden, the module members are still accessible through the module.

If a member name conflicts with another identifier or with a member of another module with the HideModuleNameAttribute attribute, then the member does not show in IntelliSense at the level of the module.

This example shows how to use the HideModuleNameAttribute attribute to add a Database object to My, which can be accessed through My.Database.

Namespace My
    <HideModuleName()> Module CustomMyDatabase
        Public ReadOnly Property Database() As MyDatabase
            Get 
                Return databaseValue
            End Get 
        End Property 
        Private ReadOnly databaseValue As MyDatabase = New MyDatabase
    End Module 
End Namespace 

Class MyDatabase
    ' The members of the My.Database object go here. 
End Class

The Namespace statement must appear outside of any classes or modules.
