Can't be done.
Files need to be saved to the viewers computer to be viewed. This includes .jpg, .gif and yes, PDF.
So, there's no other solution to only preview a PDF ?
I have tried checking the "conversion of PDF to Flash file" and displaying it to the user. But that can't be done in server side, because I'm on a shared hosting which prevents me from running commandline execution of EXE files !
Do you have an alternative to this ?
