Microsoft Office Visio stöder manipulering av OLE-objekten i Visio diagram. Om en visio-fil finns utanför Visio-filerna behöver de lägga till en 17 i dessa applikationer i Visio-filerna, och utvecklarna kan lägga till en 17-funktion i denna applikation i Visio.Aspose.Diagram for .NET API.
Manipulera programmeringsexemplet för inbäddade OLE-objekt
Objektdata egendom avForeignDataklass tillåter utvecklare att manipulera med befintliga OLE-objekt i Visio diagram. Det här hjälpämnet visar hur utvecklare kan hämta ett OLE-objekt i Word-dokumentet, redigera det med hjälp avAspose.Words for .NET API, och spara sedan tillbaka som ett OLE-objekt i Visio diagram.
