I was recently asked about switching between different Visio Data Graphics within a page, so I thought I should record a few short videos to explain how Visio Data Graphics work, how they can be edited and duplicated, and how to automate switching between them.
I wrote a post a few years ago entitled How to Run VBA Macros from a Ribbon Button in Visio 2010, and was recently asked how to add the custom buttons to an existing tab. Well, it got me thinking that I don’t really like having any VBA code in my Visio diagram documents, so I thought I would explain how all the code can be in a macro-enabled stencil so that it can be used with many different diagram documents. It turned out to be a very easy modification….
Every Visio shape must have a unique name in the collection that it belongs to, and to ensure this, Visio automatically one using the master name or just “Sheet”, if not an instance of a master, followed by a period (“.”) and the ID. However, a user can rename a shape, and Visio will then also update the universal name (NameU) to be the same as the Name. If a user chooses to re-name a shape a second time, then thee universal name is not updated … it remains as the original name.
To demonstrate this I drew a rectangle, then named, and re-named it:
I have previously written about using off-page references and labelled page grids in Visio, see A Page Grid with Labels and Page Grids and Off Page References, however a reader pointed out that the label on the Off-Page Reference shape is duplicated on both ends. This is not always ideal, however it is all I could do using just ShapeSheet formulas alone. So, in this article, I show how a VBA macro can enhance the reciprocal labels on the twin Off-Page Reference shapes, and they automatically update if either end is moved between grids. This is especially useful in electrical wiring diagrams, but the principal can be adapted for other purposes.
I work a lot with layers in Visio, and written an add-in, LayerManager, to assist, but I was asked an interesting question recently: How can shapes by assigned to layers automatically from a list in Excel? So, I thought I would present my solution. This particular request was for a Timeline diagram, where the Milestone shapes are to be on specific layers. So, I just used one of the samples provided with Visio.
[Read more…] about Assigning Visio Shapes to Layers from Excel TableI wrote an article last year about Swapping Images in a #Visio Shape manually, but I want to be able to do this whenever a Shape Data value changes. This is because I use I invariably use shapes linked to data. I also want to be able to have multiple images within a single grouped shape, and all of them changing when their referenced Shape Data values change. I believe that this will be more adaptable for a lot of scenarios than trying to repurpose Data Graphic Icon Sets ( see Make Your Own Visio Data Graphic Icons Sets … automatically). I also discovered that the Shape.ChangePicture(…) function can just as easily work with urls as it can with network file paths, so even more possibilities are opened up! For example, the Visio Online JavaScript API has the ability to overlay an image (see ShapeView.addOverlay(…)).
So, I have created some macros to provide quick and easy selection, positioning and updating of images within a group shape.
I decided to present this article with VBA code rather than my preferred C# so that a stencil could be downloaded to provide instant usability, rather than having to install an add-in. It can be download from Image Utils.vssm, and should then be placed in to My Shapes folder, so that it becomes available to open in Visio. When it is opened, then the macros will need to be enabled.
There are just five public macros:
