问题 I'm new-ish to VBA and brand new to StackOverflow, so please forgive any breaches of etiquette. I have a project to create a tool using Excel VBA that will allow the user to identify a source Excel file and then copy the print area of every worksheet in the Excel file into a slide in a newly created PowerPoint presentation. I have to use late binding because I can't assume the users of the tool will all be using the same versions of the Microsoft Office products, or that they will have
