ppt file is write protected

[PeterS]

Hi,

i scan through several ppt-files and make some modifications store them
finally. This is done by a VBA program. On few files I get the following
message (translation from german): "When you want to send this presentation
back to the original author, you should mark changes as revisions......"

How can I prevent this message or thta the program stops and the user has to
intervent.

Hi,

I looked at this, it gives "ppRevisionInfoNone" back; any further Idea to
look?

Hi Steve,

I sent the file, did you receive it?

 

[PeterS]

It was sent exactly on this E-Mail at 4/4/07 21:22 German time: I will send
again right now.

Steve,

Sorry for the delay I was collecting information. My project is written in
Delphi 7. So it is not so easy to translate to pure vba code. But what I do
is to add some information to the tag of the presentation and all slides, it
is a GUID in order to mark each slide with a unique identifier.
code like:
activeslide.tags.add(Identifier,GUID)

After this I call application.activepresentation.save.
This statement creates the error message or warning I mentioned in the first
post.

I also observed that after several trial with that file the message
vanishes. I don't know why.
