Visio 2010 Container Problems

Update : I have received a corrected response from my friends at Microsoft regarding the use of Spatial Neighbors and Containers, so I have to revise this post from its original. The changes are marked in Red.

The Structured Diagramming API in Visio 2010 is really neat, but there are a couple of problems that I think you should be aware of. The first one is about how shapes can appear to be in a container, but aren’t really; and the second is how the Container type prevents SpatialNeighbors from working … unless you use a new constant.

Let’s start with an example diagram that contains three Process shapes on a Cross Functional Flowchart. Notice that I have select the Process shape labelled A and this has caused the swimlane Function 2 to display a brown highlight … this is a good indication that the Structured Diagramming

API is working, and that Function 2 is a container shape. I have placed two more Process shapes below the swimlanes, and one of them (C) is on top of a SubProcess shape.

Changing Embedded Visio Report Column Headers

Most Visio users should know that there is a built-in basic report writer. I use it often, but I do get frustrated sometimes. I wrote a chapter about it in my 2007 book (see https://bvisual.net/resources/visualizing-information-with-microsoft-visio/ ), where I explained how you can edit the XML of an external report to change the column headers, but this can be a bit of a pain if the report is embedded in you document. Therefore, I have written some VBA code to provide the ability to edit embedded report column headers.

For example, here is a standard report for equipment within a rack:

Data Import & Export Features in Visio 2010

I have been using (Microsoft) Visio for importing and exporting data since 1996, and was an early tester/adopter of the Database Wizard features in Visio 4.1 (I think). I think of Visio as a data visualization tool, yet I cannot recall seeing a comprehensive list of the areas in Visio, out-of-the-box, where you can import and export data easily. So I decided to draw a data-linked diagram of just this for Visio 2010.

Which field is that cow in?

I reader of one of my earlier posts, Copy Data from one Shape to Another ( see http://davidjpp.wordpress.com/2009/02/02/copying-data-from-one-shape-to-another/ ) asked how a cow can inherit the field number of from the field that it in. I think that this is just an example of how you can automatically update any Shape Data value from an underlying container, but I will use a cow in a field example anyway. This example uses VBA code, but should be good to use in any version of Visio since Visio 2000.

Another Dot Grid …

My good friend, John Goldsmith, recently published a blog about how to create a printable dot grid in Visio (see http://visualsignals.typepad.co.uk/vislog/2011/02/dot-grid-backgrounds.html#more ). This inspired me to share another way that you can create a dot grid in Visio. This time I will use a custom fill pattern, rather than new shape. This has the advantage that the fill pattern can be applied to any shape, and will repeat the pattern as much as is required to completely cover the shape.

In the following example, I have just drawn a rectangle, and applied a new custom Fill Pattern, called Grid.

To create this pattern, just open the Drawing Explorer then select New Pattern from the right mouse action. Name the pattern, ensure that the Scaled option is ticked, and that the behaviour is set to the first option (repeat).

Using Character Map Symbols as Data Graphic Icons

I attended the ninth DDD on Saturday (see http://developerdeveloperdeveloper.com/ ), and, as usual, there were many interesting presentations. Sam Bourton extolled the virtues of Microsoft Expression Blend for WPF and Silverlight developers (NOT designers note!), and he showed a neat trick to create icons quickly by using Wingding symbols. Basically, he created a text block in Blend, inserted a symbol from one of the three Wingding fonts character maps, then converted the symbol to a path. It struck me that we could do a similar trick in Visio to create Data Graphic Icon Sets cheaply … so here goes…..
In this example, I am using a Process shape from the Basic Flowchart stencil because it has a Status Shape Data row that is defined as a choice from six different values (the first value is an empty text string).

Choice of Values for Status Shape Data row
