David J Parker's background has been in data visualization ever since he struggled to produce lists of hospital equipment from Computer Aided Design models of buildings as a budding architect in the '80s. He moved into building and infrastructure asset management in the late '80s using a Unix system and gradually migrated to Windows-based systems throughout the '90s. He became a European Business partner of Visio Corporation in 1996 and presented the database-linked Visio solutions that he was providing merchant banks in London and New York with at several international conferences. David started bVisual Ltd. in 1998, which provides Visio-based solutions to various industries, and became a Silver-level Microsoft partner. He has been a Microsoft MVP (Visio) for the last 12 years and has helped Microsoft Corp, UK and Western Europe, by providing Visio solutions, training, website content, and presentations. David has had several books on Visio published and has been presenting Visio/SharePoint integration courses for many years for Microsoft Western Europe, from Oslo in the North down to Lisbon in the South. He has presented at SQL and SharePoint Saturday conferences and writes a regular blog for people interested in Microsoft Visio.

What is a function?


A function defines a discrete action, and most functions take a number of arguments as input. Some functions produce an output as a value in the cell that contains the formula, whilst others redirect the output to another cell, and some do not produce a useful output at all.

The Developer ShapeSheet Reference in the Visio SDK contains a description of each of the 197 functions available in Visio 2010, and there are some more that are reserved for use by Visio itself.

Formulae can be entered into any cell, but some cells will be updated by the Visio engine or by specific add-ons, thus overwriting any formula that may be within the cell. Formulae are entered starting with the = (equals) sign, just as in Excel cells, so that Visio can understand that a formula is being entered rather than just a text. Some cells have been primed to expect text (strings) and will automatically prefix what you type with =" (equals double-quote) and close with"(double-quote) if you do not start...
