hello all

I have a question about auto run for cd's meaning when you put a cd in the drive it starts up. i know you have to have a .inf file on cd to make this work however the file i want to start up is a pdf file. how can i make a program to check to see if the user has a pdf reader installed? if they don't then have it install it then open the pdf file? of coures this would have to work on all O.S any one have any ideas on how to do this? or has anyone done this before?


thanks

Make the autorun.inf file execute a exe. The exe would then need to check to see if Adobe Acrobat is installed. If it is then make the exe do a shell execute on the pdf file. You can make this all run invisibly and it would achieve the same results - open the pdf or prompt them to download acrobat and then launch the file.

I'm not too certain but you can definately check HKEY_CLASSES_ROOT registry section for the .pdf extention to see if anything has been set for it.

Usually the easiest way is to check and see if it's installed in either the
registry or check to see if it's program files folder exists.

will that type of check work on all o.s?

thanks

I suppose a program will use the same registry keys on every os, so yes, it should work everywhere...

[tim6389]

that whats i mean the "registry keys" are the same on all o.s? meaning the same location?

thanks
