The other day, I was tasked with the problem of selecting entities from IQueryable<T> based on specific filter criteria that were only known at run-time. Basically, I had objects of different type with a set of properties. Here is an example, of what we were trying to solve. We have two expressions that apply to different types and both return […]
Recently I started developing in python (v3.8) as one of our customers asked me to implement some functionality based on a code base which is written in python. First of […]
Recently I decided to do another certification. Since I was able to gain some experience in the context of testing in the last years and because testing is an interesting and important topic, I decided to go for a foundation level certification in testing. ISTQB (International Software Testing Qualifications Board) is a global provider of such certifications. The Foundation Level […]
In this post I will show you how to easily work with Sparx Enterprise Architect Baseline information in C#. Baseline processing in Enterprise Architect is exposed via the ProjectClass (EA.Repository.GetProjectInterface()). […]
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 […]
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 […]
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 […]
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 […]
Sparx Systems Enterprise Architect supports the extension of the built-in search functionality by creating search queries with add-ins called Add-In Search. In this article I show you how to create […]
The last post in this series deals with the packaging of a WPF application. To simplify the installation of our WPF application we decided to package the application as MSI […]
During development and debugging of our WPF application some exceptions occurred which were not caught by the code. Such unhandled exceptions are not logged automatically. In order to obtain information about any unhandled exceptions in production and to simplify error analysis, we looked for a way to handle and log unhandled exceptions. After some research we ended up with the […]
After a long break it’s finally time to continue with the WPF series. Today I’ll show you how we implemented a custom metro dialog. Our dialog contains 2 comboboxes and […]
This is a follow-up to the blog post [HOWTO] Convert Images to Enterprise Architect Model Images. As already described there, we wanted to use the official cisco network topology icons […]
We wanted to use the official cisco network topology icons (B/W: EPS (7.6 MB) | JPG (4 MB)) in Enterprise Architect to associate them with elements. To avoid importing these […]
Developing an AddIn for Sparx Enterprise Architect is tedious, even with the existence of support such as the great work of Geert Bellekens. However, since Visual Studio 2015 we can […]
Sparx Enterprise Architect supports AddIns so we can enhance its functionality and behaviour in our daily work life as an architect. This is normally done by adding a subkey to the HKEY_LOCAL_MACHINE\Software\Sparx Systems\EAAddins key. This is described in Geert Bellekens’ Tutorial: Create your first C# Enterprise Architect addin in 10 minutes. As we can read in the tutorial, in addition […]
