I need to make an application that opens a pdf without opening a new window. I can't buy any third party software. I figure the only way I'm going to get away with it is to open Adobe as a Child form of my appliations main form. It would be less desirable but acceptable if I implement the program as an applet, and the applet causes internet explorer to display the PDF. I dont know if either of these option are possible. Anybody? Or is this just a lost cause and I can only open Acrobat in a new window? If that is the case I know how using Runtime.exec but how can I close Acrobat when my program closes?
