Hi All, I've asked this question before and didn't get any replies but I'll try again, I'm trying to create a UFL ( User Function Library ) for CR using C#, I've followed the sample tutorial on MS's site to the letter , but can't get the new function to show in CR. Has anyone here ever created a working UFL ? - I've looked at every google page available ( there aren't that many ) so it's pointless pasting links, this is driving me nuts !!!
