Neo4jClient–Bolt Edition

Neo4j 3.x added a new transport protocol called ‘Bolt’ in essence a binary transmission protocol to speed up connectivity to the database, and with a series of official drivers – get everyone on an even keel. Trouble is, changing from Neo4jClient to Neo4j-Driver is a big pain, for two main reasons: 1. You lose all the fluent setup you get with Neo4jClient (Cypher.Match(“”).Where(“”) etc) 2. You lose all the object mapping (.Return(u => u.As<User>())) Some people would be happy to just be ......

DotNetters–it’s time to graph up

I recently wrote an article with Michael Hunger (of Neo4j) about getting your .NET on with Neo4j - http://thenewstack.io/graph-database-neo4j-net-client/ – it’s time guys, it really is time!

Calling Stored Procs in Neo4j using Neo4jClient –the hacky way

Neo4j 3.0 introduced the concept of Stored Procedures, now, whilst they’re not the same as SQL based SPs, they work – and well – it’s what we’ve got! Neo4jClient doesn’t currently have any native way to call a Stored Proc, so to get you there in the interim, we’ll use the ‘apoc.create.uuids’ proc – which returns a GUID (or multiples) and uses both the CALL and YIELD keywords. (Sorry for lack of code highlighting….) var gc = new GraphClient(new Uri("http://localhost:7474/... gc.Connect(); ......

BrowserStack Visual Studio 2015 Extension

Do you find that you want browserstack but once again, the extension lets you down by not installing into VS2015. Worry not! As with VS2013 (that I wrote about here) it’s a case of editing the vsixmanifest file and targetting a different visual studio version. Download the extension from the VS gallery (here) open it up with 7zip/winzip/windows and edit the extension.vsixmanifest file, change the following lines from: <Installation InstalledByMsi="false" AllUsers="true"> <InstallationTarget ......

The three stages of *my* database choice

Prologue I write and run a website called Tournr, a site to help people run competitions, it helps them organise and register for competitions, keeping the scores online and taking some of the pain of competition management out for them. I began it due to a badly run competition I attended (and ahem ran) a few years ago – and I wanted to make it better for first-timers (like myself) and old-hands alike. This post is about the database decisions and pains I’ve been through to get where I currently ......

Comprehensive redesigns

So, last night I realised that I’d made some bad decisions with the database, structure and naming, so… I’ve now refactored it all, and I’m feeling… hmmm… meh about it. I suspect I will redo it all later, but for now it will do…. I’ve also come to the conclusion that I was maybe trying too much for the initial release, so as a consequence I have removed one part of the project… (which, by-the-by, I intend to have published in a month or so – and yes Andy, that is one month longer than I mentioned ......

Neo4jClient now supports JsonProperty for Sending Cypher

So, you want a demo graph, and you fire up Neo4j, go to the admin (http://localhost:7474/) and then run :play movies This gets you a graph to play around with, and so you head into Visual Studio (or maybe even LinqPad), and you have an urge now to get all the movies in the DB released after the year 2000. A compulsion if you will. So you create your class to get the movies: class Movie{ public string Title { get; set; } public int Released { get; set; }} And run the query you’ve been dreaming of ......

Neo4jClient 1.1.0.1

Big milestone this one, Neo4jClient now supports Transactions, Authentication and some other little changes. Transaction info is all here: https://github.com/Readify/... You can find the connecting stuff here (at the bottom): https://github.com/Readify/... And the other big(ish) change is the change to make the ‘CollectAs’ method return the class type specified (<T>) instead of Node<T>. Big thanks for this go to Arturo Sevilla (https://github.com/arturos... ......

Changing the VS2015 Icon in Windows 8/8.1

So – you install VS 2015, pin the icon to the start bar and ‘whaaaaaa???’ you discover it’s exactly the same Icon as for VS 2013, which is not handy. Luckily, it’s pretty simple to change that bad boy. Step 1 In the start menu, right click on the program you wish to change the icon for, and select ‘Open file location’ (in these pics, I’ve already done the update) Step 2 Right click on the icon and select ‘Properties’ Step 3 Then click on Change Icon Step 4 Pick a new Icon (I used one from: http://www.iconarchive.com/... ......

Neo4j.AspNet.Identity is Back!

In fairness, it was never *away*, but after a brief hiatus - it is being developed again. So changes – it’s moved - https://github.com/cskardon... It’s also been repackaged and nuget-ed, the instructions on the Readme have been updated and the actual database structure is better than before, it’s not all there (of course) but I will accept pull requests and any issues, open up on the github page. I’ll try to do some follow up posts with the db structure, but roughly: ......
