I use Visio Cross-Functional Flowcharts a lot, but there is one thing that really bugs me … you can move function bands\swimlanes around, but you can’t move the phases\separators in the same way. The phases/separators are containers just like the function bands\swimlanes, so why can’t I move them? Actually, it is quite understandable when you realise what is actually going on … both are contained within the Cross-Functional Flowchart (CFF) shape, but there are list containers between each band and the parent CFF shape.[Read more…] about Moving Phases/Separators in Visio Cross-Functional Flowcharts?
Visio shapes get their smartness from the formulas that are entered into the ShapeSheet, but editing these formulas can be extremely tricky and prone to error because of the lack of a modern programmer’s interface. Formulas can be quite long (up to 64k characters) but even medium size ones like the one in User.GetWorkdays cell below from an earlier article can become a challenge. I have been using Notepad++ for many years to copy and paste the formulas from a cell so that I can split the text into multiple lines, and to see where the bracket pairs are. My good friend John Goldsmith pointed out that I can record a macro in Notepad++ and create a custom language style. So together we improved our environment for editing ShapeSheet formulas.[Read more…] about Using Notepad++ to Edit Visio ShapeSheet formulas
I was recently asked if a second function header bar can be added to the swimlanes in the cross-functional flowchart templates in Visio. Some swimlanes can get quite wide, so it can be useful to have a duplicate function header shape on the far-side too. It is quite simple to duplicate the existing function header sub-shape and then change its position to the opposite side of the swimlane.[Read more…] about Adding a second Function header bar to Visio swimlanes
My last article looked at parsing an XML string with a known structure and order of elements and attributes. This can be acceptable in some scenarios, but what if the elements or attributes are in a different order? Then it is necessary to use the element and attribute names rather than their index position. This requires a little more complexity to the ShapeSheet functions, and this can result in longer processing time, so needs to be used cautiously, but it is possible, as I demonstrate in this article.[Read more…] about More Parsing XML Data in Visio Shapes
One of my current projects uses XML data, and some of the values in the XML data control the display and content of Visio shapes. Therefore, I looked deeper into how the XML data can be used directly to control parts of the graphics.
Although the external data linking feature in Visio Professional and Visio Plan 2 does have the ability to use XML files, the structure of these XML files is in a particular ADO format, and not suitable for the XML data in this project.
Also, Visio documents can have embedded XML data within it, and there are several methods available to work with the XML, such as Document.SolutionXMLElement. In fact, there are several ShapeSheet cells that can also hold SolutionXML too, as found in the Visio SDK :
The cell must be an A through D cell of the Scratch section or value cell of the User or Custom Properties section.
Custom Properties is the former name of Shape Data, and the SDK contains sample code for putting XML into the Document and a ShapeSheet cell. Unfortunately, the SolutionXML functions only work with the Document, not with a Cell.
Again, there does not seem to be a compelling reason to use SolutionXML with shape cells in my current project because it just adds extra characters, and slightly modifies the XML characters.
Visio cells can store very large amounts of text within them, and in this particular project, I have well structured XML with predictable elements and attributes. Similarly, there are many variations of books.xml on the web, ( small, medium, large ) which I have used for this article to demonstrate what can be done with XML in shapes.
In my case, I have created a Visio shape which has a Shape Data row to store the XML data, and other User-defined Cells to parse the XML data, then more Shape Data rows to just check the contents. I then have a 20 book sub-shapes that can become visible and display the information in the parent XML data automatically:[Read more…] about Parsing XML data in Visio Shapes
I suppose I should explain what I mean by dirty text first 🙂
I often display the value of a Shape Data row in Visio text, but sometimes the solution requires that the value is also editable. This is ok if the client accepts that all editing is done with the Shape Data window or dialog, but not if the user more naturally wants to edit the text in the shape. In my current solution, I want to pass the manually edited text to another process for checking, and then only update the Shape Data row when validated or accepted, before re-setting the text with the inserted field. My first task was to spot with text had been manually overtyped, so I decided that checking the value of a new User-defined Cell, called IsDirty, was best, and then this value can be used to change the color of the text (or it could be the LineColor or FillForegnd) to make this value visible.
When Insert / Field is used in Visio, it creates a Text Fields section which can hold the reference to the inserted field.
If the text is manually overtyped, then the rows in the Text Fields section get deleted.[Read more…] about Highlighting dirty text in Visio shapes
