CustomPropertiesPart

General

CustomPropertiesPart és una classe en Aspose.Slides FOSS per a C++.

Parse i serialitzar docProps/custom.xml. Gestiona un diccionari de propietats personalitzades anomenades, cadascuna amb un valor digitat (string, int, double, bool o datetime). Les propietates es creen lentament: la part XML només s’escriu quan se l’apella save() i la parteja és brut.
