TypeLibTypeAttribute Class
Assembly: mscorlib (in mscorlib.dll)
'Declaration <ComVisibleAttribute(True)> _ <AttributeUsageAttribute(AttributeTargets.Class Or AttributeTargets.Struct Or AttributeTargets.Enum Or AttributeTargets.Interface, Inherited:=False)> _ Public NotInheritable Class TypeLibTypeAttribute Inherits Attribute 'Usage Dim instance As TypeLibTypeAttribute
/** @attribute ComVisibleAttribute(true) */ /** @attribute AttributeUsageAttribute(AttributeTargets.Class|AttributeTargets.Struct|AttributeTargets.Enum|AttributeTargets.Interface, Inherited=false) */ public final class TypeLibTypeAttribute extends Attribute
ComVisibleAttribute(true) AttributeUsageAttribute(AttributeTargets.Class|AttributeTargets.Struct|AttributeTargets.Enum|AttributeTargets.Interface, Inherited=false) public final class TypeLibTypeAttribute extends Attribute
The Type Library Importer (Tlbimp.exe) applies this attribute to classes or interfaces.
This attribute is applied when a type library is imported and should never be changed. It is only applied when the method's TYPEFLAGS evaluate to non-zero. The attribute is designed to be used by tools that need to know how the original TYPEFLAGS were set. The common language runtime does not use this attribute.
The following example demonstrates how to get the TypeLibTypeAttribute value of a class or interface.
Imports System Imports System.Runtime.InteropServices Module B Public Function IsHiddenInterface(ByVal InterfaceType As Type) As Boolean Dim InterfaceAttributes As Object() = _ InterfaceType.GetCustomAttributes(GetType(TypeLibTypeAttribute), False) If InterfaceAttributes.Length > 0 Then Dim tlt As TypeLibTypeAttribute = InterfaceAttributes(0) Dim flags As TypeLibTypeFlags = tlt.Value Return (flags & TypeLibTypeFlags.FHidden) > 0 End If Return False End Function End Module

class ClassB
{
public static boolean IsHiddenInterface(Type InterfaceType)
{
Object interfaceAttributes[]
= InterfaceType.GetCustomAttributes(
TypeLibTypeAttribute.class.ToType(), false);
if (interfaceAttributes.length > 0) {
TypeLibTypeAttribute tlt
= (TypeLibTypeAttribute)(interfaceAttributes.get_Item(0));
TypeLibTypeFlags flags = tlt.get_Value();
return (int)(flags & TypeLibTypeFlags.FHidden) != 0;
}
return false;
} //IsHiddenInterface
} //ClassB
