Class (inherits from MemberInfo)

Provides information on the attributes of an item via the Introspection system. Attributes are added to project items using the Inspector.

Properties
IsPrivate IsPublic Value
IsProtected Name


Notes

For attributes of classes, attributes are inherited from the parent class and attribute values are overridden if redefined by the subclass.

Add attributes to project items, methods, properties, constants, etc. by using the "Advanced" tab on the Inspector.


Examples

Suppose Window1 has three attributes: The first attribute contains the Name only and the others have both a Name and Value:

Name Value
myName1
myName2 "Foo"
myName3 23

The following code retrieves the attributes and displays them in a ListBox:

Dim myAttributes() As Introspection.AttributeInfo = Introspection.GetType(Window1).GetAttributes

For i As Integer = 0 To UBound(myAttributes)
ListBox1.AddRow(myAttributes(i).Name)
If (myAttributes(i).Value.IsNull) Then
ListBox1.Cell(ListBox1.LastIndex, 1) = "No Value"
Else
ListBox1.Cell(ListBox1.LastIndex, 1) = Str(myAttributes(i).Value)
End If
Next
