How to display a picture or PDF file stored in ValueStorage object on Web-client?
For thin client I extract file, save it to temp file and then use RunApp( "file:///" + StrReplace( Filename, " ", "%20" ) ). On Web-client this method does not work. Gives me an error message "The operation attempted is not supported".

Is it possible in Web client to open a picture or PDF file stored on web server using web browser through HTTP connection?

To display PDF file I created PDFDocument object, then from BinaryData extracted from ValueStorage object I created Stream, after that read PDF file content from created Stream to PDFDocument object and displayed it on screen with Show() method.
