Class StdLibClassAttribute
Marks an interface as the internal representation of one of the standard library's predefined class modules (MS-VBAL §6.1.3).
[AttributeUsage(AttributeTargets.Interface)]
public sealed class StdLibClassAttribute : Attribute- Inheritance
-
StdLibClassAttribute
- Inherited Members
Remarks
A predefined class module is a class module: it is a nameable type an As clause can bind,
and its members resolve only through an instance of it.
The marker is what makes the class discoverable - every VBA project has the standard library whether or not anything references it (RD-VBAL §6.1), so nothing declares the set of classes a workspace gets, and the set is read off the SDK itself.
Constructors
StdLibClassAttribute(string?)
Marks an interface as the internal representation of one of the standard library's predefined class modules (MS-VBAL §6.1.3).
public StdLibClassAttribute(string? name = null)Parameters
namestringThe class's name in VBA source, when it differs from the conventional one.

Properties
IsCreatable
Whether VBA source can create an instance of this class with New.
public bool IsCreatable { get; init; }Property Value
Remarks
true by default - New Collection and New RegExp are both valid. A class
whose instances only ever come from the environment, the way an ErrObject comes from the
Err function, sets this to false so that New on it is reported rather than
resolved.
Name
The class's name in VBA source, or null for the conventional one: the declaring
interface's name without its IStd prefix and Class suffix, so
IStdCollectionClass is Collection.
public string? Name { get; }Property Value
ProgId
The programmatic identifier the class answers to in CreateObject (VBScript.RegExp), if it has one: the name of a COM class the platform
implements itself, found before the machine's own servers are asked - which is what makes a program that creates one by name portable to a machine that
has no such server.
public string? ProgId { get; init; }Property Value
Remarks
The part after the last dot is the name of the class.
TypeName
What TypeName says of an object of the class, when it is not the class's name: the VBA library's UserForms collection is an object whose class
MS-VBA names nothing, and TypeName(UserForms) is Object (Excel-measured, oracle\s41 U01).
public string? TypeName { get; init; }
