Modify Powerpoint on runtime (maybe with memory manipulation?).

[Murmelmann]

Hi,

I am trying to modify parts of a running (!) Powerpoint presentation.

I would like to change the types (e.g. "datetime2") and values (e.g. "Dezember 2020") of fields (<a:fld>) in textboxes. This information is normally stored in a XML-file but i cannot seem to change the XML while Powerpoint is running. Please note that I don´t want to replace the field with a new one, instead I want to change the existing one.

AFAIK this is not possible with Open XML, COM, VBA or directly in PPT. Therefore I would like to ask you for other approaches such as memory manipulation. Does anybody here have any experience with this, especially with respect to Powerpoint?

Thanks!

Why?

Why?

The problem is that I need to be able to identify parts of texts (i.e. not whole shapes) with some identifier in order to change them programmatically. Fields have a unique ID and if I could change their type and value while PPT is open I could achieve my goal. Please note that this already works when editing the XML of the closed presentation - but i don´t know how to do it on runtime.

Still no nearer to why?

If you want to do animations, then this.

If you're trying to do something like "live stock market prices" in powerpoint, then there is such a thing as using the wrong tool for the job.

And we're back to "why" again.
