New Requirement for VBA Digital Signatures in Visio

Like most developers, I have to buy a new digital certificate every 3 years to sign my Visio add-ins and VBA projects. Usually that means verifying my bone fides, paying the fee and downloading the certificate, but security has been increased, and now, like everyone else, I have to use a USB key with it on (see Code signing changes in 2023 (digicert.com)). This requires the use of an application such as one from SafeNet that enables the signing of code. This is working for my Visio addins written with Visual Studio, but the VBA macros appeared to be signing until I tried to save the document.

How SVG in Visio can cause a Shape.BoundingBox(…) error

I have used Visio’s Shape.BoundingBox(…) for many, many years and I cannot ever recall it failing, but I have now managed to create some shapes that cause it to error. This caused many hours of confusion, so I nearly abandoned using the method, until I discussed it with my fellow Visio MVP, John Goldsmith (see…

Post-Processing Paste from Clipboard in Visio

One of my current Visio VSTO add-in projects requires me to react to users pasting custom shapes in the Visio page from the clipboard.
