Protecting the integrity of custom Visio masters

All of my Visio solutions contain custom masters because this is the best way to create smart shapes that respond to user’s needs. This usually means creating Shape Data, User-defined Cells and Action rows that govern aspects of the shape with formulas designed to provide an efficient user interface. As a developer I sometimes forget that other users may not perform the same actions as I do, and can accidently undo all my intended behaviour. For example, in recent testing of a visual stream mapping system that I am working on, my carefully constructed master-shape relationship was being broken by grouping some of them together, thus changing their behavior and hiding them from some of the custom functions. The reason given was to that they want to create copies and this seemed like a reasonable way to do it. Now, I have known that this is bad ever since my original Visio developer training back in 1996, so I always avoid doing this, and erroneously thought that other would know this too. I was wrong to be so myopic, so I explored how I can best prevent this and other user actions that could break the intended master-shape relationship.

  • Multiple instances of a single master shape
  • Locking some properties of the shape
  • Modifying group behaviour

Docked Stencils in Visio for the Web

Visio desktop has multiple ways to specify the folder where docked stencils can be found, but, as far as I am aware, Visio for the Web only has one. I mostly create VSTO add-ins for Visio desktop, and I use Visio desktop as a studio for creating templates for Visio for the Web. Often, I leave the Document Stencil in the template open because users can then drag and drop from there, but when I create an installation with custom stencils then they normally go into the application folder, or a sub-folder of it. An alternative is to install them into the My Shapes folder in the users desktop Documents folder. These will appear in the Visio desktop UI. Also, there is the ability to set the Stencils folder using File | Options | Advanced | File Locations. Finally, the desktop edition will always first check the folder that the Visio document is in for any docked stencils. Visio for the Web does not have all these options, so how do you get any custom docked stencils to appear when you use Visio for the Web to edit a document?

My Visio Books and Old pre-C# Work

We, as a family, are in the process of de-cluttering our house for hopefully a move closer to the south coast, so I decided to take a photo of my Visio books collection, and as you can see, back in the mid-1990’s, I started reading and learning from other peoples works, and then progressed to writing my own from 2007. This shows how mature the Visio desktop product is, and as very little has been removed, then each book has something to learn.

Migrating from Lucidchart to Visio?

My fellow Visio MVP, Michel Laplane, and I recently converted and transformed 15k Lucidchart documents to Microsoft Visio for a large multi-national organization. This was approximately 4 years after they had moved from Visio to Lucidchart! I do not know the full reason behind these changes in technology, and I do not have a particular dislike of Lucidchart, but my passion is Visio, so I was willing to assist SohoDragon in this migration for their client. The Lucidchart application is solely a web-based diagramming system with the documents stored in AWS, so perhaps it does not fit easily within the corporate compliance architecture of Microsoft Azure, Teams and SharePoint. Microsoft Visio though has the same files for both the desktop and web editions, although there are some restrictions in the size and features of editing Visio document in the web. However, all the M365 users will have the ability to view and comment of the Visio documents that they have permission for. Visio Plan 1 or Plan 2 subscriptions will be required for editing the migrated documents because they have not been created with the templates provided in Visio for M365, and Visio documents which have any page with over a thousand shapes will currently only be editable in the Visio desktop edition. The Lucidchart documents needed to be audited, exported and transformed into Visio documents, and then uploaded to similar folders in SharePoint, where user permissions could be applied. We decided to use multiple secure Windows VMs to process the documents and then upload them to SharePoint before the VMs were deleted.

Creating Boolean Context Menus in Visio

Over the many, many years that I have been creating Microsoft Visio solutions, I have had to create numerous right-mouse context menus for shapes to control their Shape Data values. Over that time, patterns emerge, so this article is highlighting three different appearances for simple Boolean values, otherwise known as True/False or Yes/No values, and even for tristate Yes/No/Maybe. In fact, Visio presents you with Boolean as one of the eight types of data available on the Define Shape Data dialog, but there is no UI for creating accompanying right-mouse context menus except for the ShapeSheet window. However, I will show that using a Fixed List type is often preferable to a simple Boolean type.

Installing Visio Templates and Stencils

I was recently on holiday but needed to update an installation of Visio Templates and Stencils for all languages. I use Advanced Installer in Enterprise mode so that I can edit the PublishComponent table like I have described in my earlier article ( see Using Advanced Installer with Visio VSTO Add-Ins – bVisual )Unfortunately I only had my travel laptop and could not refer to previous projects. Instead I referred to an excellent article on UnmanagedVisio, and tried the suggested Component IDs for All Versions of Templates and Stencils

However, these do not work for me using Visio Plan 2. Nothing showed up in the Visio UI. So, this article describes how it works for me using Advanced Installer.
