Greetings Gang, How do you acquire and alter the properties of a SheetSets IAcSmFileReference object? Here's the situation. I have appended code to the example sheet set VBA project file. The idea is to use the subset names as the new sheetset location folders. When you make a new sheet set the existing sub folders are used as the names of the subsets - for us, it would be ideal if the new sheet set location used the same folder (maybe we will adopt different concepts as we become more familiar with sheet sets). Anyway, the setnewsheetsetlocation subset method uses a IAcSmFileReference object and not a string to set the location. I just dont know how to acquire or use this object. The below code is appended to the SheetSet class in the example sheet set project. This line: FR.SetFileName RootFolder & Right$(SSetPath, Len(SSetPath) - 1) produces this error: The owner of the PerUser subscription is not logged on to the system specified. Help! Please! ... Thanks, Kevin.
