I have written many COM and VSTO add-ins for Visio, but got confused when a client recently reported that the following Custom UI Runtime Error was appearing. I wasn’t getting the same error on any of my test laptops, so I chatted with my good friend, and fellow Visio MVP, John Goldsmith ( John Goldsmith’s visLog (typepad.co.uk) ). He gave me an excellent tip….

And what was the error?

Developer Mode for advanced Layer Manager actions
I have had more than one person ask me how to see the full Layer Manager panel, so I must have not made it clear enough in the help file. Visio has a Developer Mode that is simple to switch on, and provides some extra functionality, including a Developer tab in the ribbon. Layer Manager…

My good friend Scott Helmers, Visio author and trainer, of Harvard Computing Group , recently asked for some help in keeping data graphic items level when their target shape is rotated.
