TypeLibFuncAttribute Class
.NET Framework 3.0
Contains the FUNCFLAGS that were originally imported for this method from the COM type library.
Namespace: System.Runtime.InteropServices
Assembly: mscorlib (in mscorlib.dll)
Assembly: mscorlib (in mscorlib.dll)
'Declaration <ComVisibleAttribute(True)> _ <AttributeUsageAttribute(AttributeTargets.Method, Inherited:=False)> _ Public NotInheritable Class TypeLibFuncAttribute Inherits Attribute 'Usage Dim instance As TypeLibFuncAttribute
/** @attribute ComVisibleAttribute(true) */ /** @attribute AttributeUsageAttribute(AttributeTargets.Method, Inherited=false) */ public final class TypeLibFuncAttribute extends Attribute
ComVisibleAttribute(true) AttributeUsageAttribute(AttributeTargets.Method, Inherited=false) public final class TypeLibFuncAttribute extends Attribute
Not applicable.
The Type Library Importer (Tlbimp.exe) applies this attribute to methods.
This attribute is applied when a type library is imported and should never be changed. It is only applied when the method's FUNCFLAGS evaluate to non zero. The attribute is designed to be used by tools that need to know how the original FUNCFLAGS were set. The common language runtime does not use this attribute.
The following example demonstrates how to get the TypeLibFuncAttribute value of a method.
Imports System Imports System.Reflection Imports System.Runtime.InteropServices Module C Public Function IsHiddenMethod(ByVal mi As MethodInfo) As Boolean Dim MethodAttributes As Object() = mi.GetCustomAttributes(GetType(TypeLibFuncAttribute), True) If MethodAttributes.Length > 0 Then Dim tlf As TypeLibFuncAttribute = MethodAttributes(0) Dim flags As TypeLibFuncFlags = tlf.Value Return (flags & TypeLibFuncFlags.FHidden) > 0 End If Return False End Function End Module

{
Object methodAttributes[]
= mi.GetCustomAttributes(TypeLibFuncAttribute.class.ToType(), true);
if (methodAttributes.length > 0) {
TypeLibFuncAttribute tlf
= (TypeLibFuncAttribute)(methodAttributes.get_Item(0));
TypeLibFuncFlags flags = tlf.get_Value();
return (int)(flags & TypeLibFuncFlags.FHidden) != 0;
}
return false;
} //IsHiddenMethod
