[Bug] Sparx Enterprise Architect v14.1 Build 1429 not triggering EA_OnPostCloseDiagram event in context of Time Aware Modelling

When cloning a structure in Sparx Enterprise Architect (EA) as a new version, that contains at least one diagram, every newly created diagram (clone) gets quickly opened and closed again during cloning process. In EA v14.1 build 1429 the EA_OnPostOpenDiagram events can be caught successfully however the EA_OnPostCloseDiagram are not thrown by EA in this case. I figured this out […]

[NoBrainer] Simplifying and Speeding Up Testing in Sparx Enterprise Architect

Today’s post will be rather quick. I will show you how a unit/integration test class that can interact with real model data in Sparx Enterprise Architect. Beyond the well known Interop.EA assembly there is another assembly called SparxSystems.Repository that provides the intersting feature to connect to a running EA instance: Services.GetRepository(). We can use this to write unit/integration tests that […]

Dynamically registering UserControls in Sparx Enterprise Architect AddIns for showing them with Repository.AddTab

Sparx Enterprise Architect provides a means for AddIns to display Windows via Repository.AddTab() which are based on System.Windows.Forms.UserControl. However the call AddTab expects a name for the actual tab and a PROGID. EA actually takes this PROGID and loads the UserControl via the registry (as it is actually an Active COM Control). In this post I show you how these […]

Improvements on the SqlXmlSerialiser

This is a followup to the last article Easy Conversion from Enterprise Architect XML SQL Queries to C# Objects. Every time we execute a query that returns results from more than one table we have to use aliasing in the SQL statement to differentiate columns with the same name. See below a query that retrieves all connectors of an element […]

Easy Conversion from Enterprise Architect XML SQL Queries to C# Objects

In this article I show you how to easily convert arbitrary SQL query results in Enterprise Architect to native C# objects. The Enterprise Architect object model provides several methods which you can use to make direct SQL queries against the underlying database. And while Repository.GetElementSet really returns a Collection of native EA.Elements (but not connectors) the more versatile Repository.SQLQuery only […]
