Today I would like to present you a simple ODATA search controller that you can use in LightSwitch (or any other ODATA consumer) to look up user accounts (and possibly other objects). When using SharePoint you will probably know the very convenient PeoplePicker. However, in LightSwitch (HTML) there is no equivalent to that. You certainly have “Person” objects/data types but […]
Today I show you how you can quickly use “JayData” to modify the contents of a LightSwitch HTML “drop-down list” (aka “choiceList”). Though it does not really offer all the blows and whistles as other controls such as “select2” it has some advantages like easy setup and good visual integration. And now with the use of JayData (and certainly with […]
Following the very cool series of ODATA articles on the ASP.NET site by Mike Wasson you will see that it is possible to define actions not only on entities directly, but also (unbound) on entity sets and the service root itself. While it is fairly straightforward to implement entity set action (the same as an entity action but without the […]
This is a quick addition to my previous blog post on how to receive SignalR messages via PowerShell. Once you have established a connection in PowerShell to your SignalR hub you can easily them a message to the server via the ‘Invoke()’ method on the IHubProxy object. In it you specify the name of the method you want to call […]
A couple of days ago I wrote about how to use RabbitMQ with AMQP from PowerShell (via a small assembly that utilized the original C# .NET Client). After I implemented it in the use case for our customer I somehow felt it to be “too heavy” for what I was really using it (compared to all the features AMQP has to […]
I was working on a project where I needed a pool of PowerShell workers that were distributed across several nodes and should be served by a central dispatcher. So why not give AMQP with RabbitMQ a try? The setup was very easy thanks to the documentation. And besides plenty of .NET library wrappers around “Rabbit.MQ.Client.dll” there were even two PowerShell […]
A quick follow up on my last post regarding TFS and PowerShell. I found it quite amazing that is so little documented and relatively difficult to download a file from TFS to your local machine. I would have expected that the supplied Cmdlets in the TFS Power Tools snapin will just handle that for you, as I find the requirement […]
Today I was playing with TFS Power Tools to check in some PowerShell scripts where I ran into a strange error. Obviously I wanted to use the PowerShell Cmdlets for that you can select via the ‘Custom’ option in the ‘Power Tools’ installer … For a quick intro on TFS via PowerShell you can have a look at PowerShell and […]
I just came across another nuisance in .NET WebAPI that I want to share with you quickly. In one of our LightSwitch projects we use WebAPI ODATA controller to help out when LightSwitch internal capabilities come to their end. As we are using a PowerShell once in a while as you might already have guessed from our web site we […]
In this post I quickly describe how you can use the select2 plugin with LightSwitch HTML client and present data from ODATA sources via jaydata. LightSwitch has builtin capabilities for selecting related entities via the ‘Modal Data Picker’ control. You can also have drop down or choice lists with static data, however they lack the convenient search and filter mechanisms […]
It might sound old school and the JIRA SOAP service is announced to be removed with version 7 (https://developer.atlassian.com/display/JIRADEV/Preparing+for+JIRA+6.0#PreparingforJIRA6.0-SOAPandXML-RPCdeprecatedinJIRA6.0) but the JIRA SOAP protocol is really easy to use from PowerShell as of the nifty ‘New-WebServiceProxy’ Cmdlet that abstract the SOAP protocol behind typed .Net objects. So whenever you want to do a quick upload of a screenshot or get […]
[UPDATE] 2014-11-28 Jerther sent me a comment (see below) on how he solved this issue! So how did he do it? The short answer is, that you have to include special registration code inside the ‘Application_Start()’ and other places where the order on how you code it plays a crucial role. Check out his post ASP.Net: Web API 2 + […]
This will be a quick post about WebAPI and ODATA controllers, and a strange “bug” or behaviour I found. I was not aware of this, so maybe it is also of some interest for you. When you create an ODATA service via WebAPI and want to connect two or more entity sets via a relation the standard example will tell […]
Graylog2 comes with a very limited alerting feature where you can basically only create alerts based on a single field. However, and thus far I can follow the motivation of […]
Graylog2 is a powerful and scalable open source log management and data analytics system on top of elasticsearch. Since our logging module is based on log4net, the integration of Graylog2 […]
As you might have already heard and tried out with .NET 4.5 (or so) Microsoft blessed us with a new and shiny HttpClient that should be easier to use, support async programming and (that’s best) finally allow the user to set any headers without reverting to some workaround code (cf. WebClient and its underlying classes). And it is actually true […]
