Dynamically update powerpoint 2010 slides from text files

Hi Team,

   We have a small Help Desk team and we want a looping powerpoint presentation that dynamically reads small text files and displays them on different slides.   For example,
Slide 1   --> opencalls.txt
Slide 2  -->  Sev1calls.txt
Slide3  -->  Callsfortheday.txt
 etc.

First, we have scripts that automatically creates these *.txt files and they change all the time.  I tried  embedding the link of the text object to the slides but they don't update when Powerpoint loops back. You have to manually *refresh* the link.

I tried searching in this forum and most relate to linking Excel to Powerpoint.  But our scripts can work only with text.

I am not familiar with VBA (I can learn the basics if required) but would someone have a simple VBA macro that can help me accomplish the task above?

Thanks very much

Hi DamjanDemsar,

   thanks for this very useful plugin.   Now I am experiencing a side effect.  While I have the Powerpoint in a loop,   I am trying to update a test.csv file (plain text) which is linked to the Powerpoint presentation, now I can no longer update it due to the error  -- "The Process cannot access the file because it is being used by another process".  It seems that the running Powerpoint presentation is locking the test.csv file.

I even tried to create another file called test2.csv and do a copy test2.csv test.csv, and with the same error message.

How do we tell Powerpoint to *open* the file for read only, without locking it?

Thanks very much.

Hmm, I did a test, and it does not happen here.

How did you insert the csv file?

does it happen also without the addin?

Hi  DamjanDemsar,

It's working now, thanks.  I tried your solution at home initially, but in the office, I was using XP, a different slide deck, less animations, etc.   Not sure what the issue was, but it's working in my office PC, which is what the target setup is.

Thanks for all your help.
