For example:
DECLARE INTEGER ShellExecute ;
IN SHELL32.DLL ;
INTEGER nWinHandle,;
STRING cOperation,;
STRING cFileName,;
STRING cParameters,;
STRING cDirectory,;
INTEGER nShowWindow

? ShellExecute(0,"print","c:\acrobat3\reader\acrobat.pdf","","",1)

>I have a folder full of pdf files. How can I use code to print the pdf file without opening Acrobat?
