I'm trying to make a COM based PDF UDF. (Say that 3 times fast!) I've been using this documentĀ and the attached document for reference. I'm stuck at getting the documents to open in Acrobat... I can create the App and make it visible, but I can't get the documents to be visible inside. I've managed to edit the AcroExch.PDDoc object (while it's hidden), but I can't get anything to be visible in the AcroExch.App. There doesn't even seem to be property that sets what document the app is lookin
