Working with Connected Diagrams Programmatically, part 1

In a previous blog post, we told you about the new Connectivity APIs in Visio 2010 that make it easier for developers to create and to move across a connected diagram. We’ve shown you how to use some of the new APIs to create new connected shapes; this blog will examine techniques for traversing connected diagrams. One of the most useful APIs for analyzing a connected diagram is the Shape.ConnectedShapes method, which allows you to get a reference to the shapes connected to a shape.

Visio 2010 XML Schema Definition Released

Visio has published the XML Schema Definition (XSD) files for the Microsoft Visio 2010 XML Drawing (.vdx) format. This schema is also known as DatadiagramML. The .XSD files allow developers to better understand the structure of Visio XML documents and design solutions that work with the .VDX file format.

New Visio 2010 API for Configuring Raster Export

Visio developer typically want to automate the export a diagram as a raster image in the PNG, JPG, BMP, or TIFF format for use in a web page or other applications. In this post, we’ll talk about the additions to the Visio object model that let developers configure each of these raster export settings.

User Interface Extensibility in Visio 2010

Learn about RibbonX, a XML markup that allows developers to customize the Office UI. It enables 3rd party developers and solution providers to build custom tabs and groups on top of the Ribbon, and target scenarios unique to and optimized for their customers. As Visio adopts the Fluent UI, Visio developers now also have the opportunity to utilize this platform to build and customize Fluent UI to offer users a more discoverable and instructive UI experience.

The Visio Services JavaScript Mashup API

If you need more flexibility in creating rich diagram mashups than offered out of the box by web part connections, you can use the Visio Services JavaScript Mashup API. In this post we'll review the breadth of possibilities by the Visio Services Mashup API and show you how to get started coding with a few simple examples.

Getting to Know Your Neighbors – Quickly

Visio's SpatialNeighbors property is useful for finding shapes that are nearby other shapes or that overlap other shapes. It can be used to programmatically answer the question "What did I drop my shape on top of?". This blog discusses the SpatialNeighbors property.
