[lfeliz]

I am tryng to use the CGJQPDFViewer to view a PDF file from the Cache folder.

I am copying the file to the Cache and setting the  

I get the error in the PDF viewer :

Message: Missing PDF "http://127.0.0.1:8888/$/MyApp/zHOG5EAdJuoVjqQJqQUg9W/EXP_20170525_583001.pdf?cache=1731781782136".

The file acually does exist in the temporary cache folder ???? I even test that it exists before I assign the value

s1 := WebApplication.UserCacheDir+ExtractFileName(UserSession.qry1DocFile.Value);
s2 := webapplication.UserCacheUrlBase+ExtractFileName(UserSession.qry1DocFile.Value);


  if fileexists( s1)then
      PDFv1.JQPDFViewerOptions.PDFFileName:= s2;

Well,  for now,  the application I am working with runs on a local network or via local VPN access and is not public.  So I am deploying the app on server where docs are stored and using  Windows Sym Link  in he wwwroot folder to make things work without the  local cache until I can find a way to make that work.  The PDF viewer component allows a nice embeded viewer and users dont hav eto deal with coutless windows opening up.  I actually switched to using the TIWURL Window (had some non-pdf items that client need to view) and same issue.  You would think you can included content from the apps temporary file cache since I have used it to send files...

Hi,
I also have a similar problem, I would like to use this component to view a file present on the PC where the application resides (Stand alone) and I tried the instruction like:
IWCGJQPdfViewer1->JQPDFViewerOptions->PDFFileName = "PDF_Example.pdf";

But I get a result like this

PDF.js v1.10.88 (build: c62a1938)
Message: Missing PDF "http://localhost/PDF_Example.pdf?cache=1735839201467".

Can someone help me to use this object?

Hello,  I finally go this working by using the Cache  , see snippet below . I also switched  using the TIWURLWindow as my documents are more than just PDF.

Hope this helps
