I have started to rewrite the PowerPoint UDF similar to the Word, Excel and Outlook UDF. The new UDF will not be compatible with the existing one. I will add examples, documentation, a section in the wiki etc. So far the following functions have been coded - more are on the ToDo list. _PPT_Open: Open a connection to a running instance of PowerPoint or start a new one _PPT_Close: Close a PowerPoint instance _PPT_CommentAdd: Add a Comment anywhere on a Slide or connected to
