extract "standard" and "specification" properties from toolbox components with the API (VBA)

Hello, I would like to extract "standard" and "specification" properties from toolbox components with the API (VBA). These information are accessible from BOM tables (Toolpbox Property), but in VBA I don't find the way to extract these info (not in configuration or custom property manager). Has anybody an idea ? Thank you
