You're being incredibly lazy, since it's part of the FFC, you have the entire thing sitting right there in VFP, and there have been hundreds of threads on this and similar topics in the past two months. Include the _environ.vcx from the FFC in your project

oShellExecute = NEWOBJECT('ShellExecute','_environ.vcx')
oShellExecute.ShellExecute('name of the file.pdf')

>Word, i can open it from vfp, is no similar code to open a pdf file.

It works the same way for Word - specify a .DOC, it fires up Word, specify an .XLS, it starts Excel, etc. There's no magic.
