Opening pdf in read only mode

Post by alessandro.borsari »


in our multi-user application, once a user modifies a document,
the corresponding pdf file is deleted and re-created to let everyone see the updated file.
However, this mechanism is blocked if the pdf is still In-Use.
To open a pdf we use ActiveX control PDFXCviewAx.CoPDFXCview.
Once the pdf is open, it is kept locked and cannot be deleted/modified.
Is there a way to open the pdf in just read-only mode?
We need to avoid the pdf being locked.

I really appreciate any help you can provide.

Hello alessandro.borsari,

The Viewer SDK is quite old and I do not have it here for testing but there are get_ and put_ methods for setting a ReadOnly flag for all documents. Please check section ReadOnly
of the Viewer AX SDK manual (page 286).

Kind regards,
