Hello Vitamine, Thank you for your reply! Yes, I was not precise in my previous post. I had to mention that the PDF is displayed by AdobeAcrobat, which is called by a Java Script code from inside the HTML page. The HTML page is handled by MS Internet Explorer. I do not know how exactly Anita does this, but when anita is invoked with the following parameter: "\\computername\folder\test.html?file='/myfolder/myfile.pdf'" it will display the PDF file. Thank you for your help!
