Hello
Thank you for your reply.
My problem is not accessing the file, my problem is how to view that pdf, I explain why. I am using Chrome in kiosk mode, for this reason I need to see that file inside the dahboard (I have managed to open the file and open it but I get out of the dashboard).
More details in the following images
Sorry Friend.
I am no expert in this subject, the link I suggested also has information on how to embed a pdf viewer in a browser so i thought it might be of value to you.
There are many experts on this forum, give some time, some one will respond to you hopefully.
