Softata : Open AI and Enums with Blockly & Swagger Part 3 September 17, 2024 23:25 David Jones MVP softata openai blockly swagger enums The previous two posts discussed Blockly and Swagger Controller methods that take enum types as a parameters. With Blockly, each enum type so used, manifests as a block with a dropdown list of the enum literals. How can that be used for a controller parameter where the enum literals depend upon another parameter to the block. In particular, for the Display.Misc() method where each display type has a different enum list of miscellaneous options.

Softata : Custom Blocks via ASP.NET Controller June 01, 2024 18:45 David Jones MVP softata rpipico firmata arduino csharp grove swagger asp.net blockly Using NetCoreBlockly you can create custom blocks. As an alternative you could “outsource” some functionally to an ASP.NET Controller. In this example, a menu is sent as a CSV list of options to a controller method which returns a single formatted string with each item on a separate line and each item is proceeded by its index (numerical order from 1 in the CSV list) which is used in the menu selection. This can then be used with the NetCoreBlockly block prompt for number with message to prompt for a selection from the list.

Meltdown : Coding November 29, 2021 20:32 David Jones MVP web markup markdown email blazor csharp The previous posts on Meltdown, hopefully demonstrate that it is easy to generate an email message that only requires basic formatting, that is HTML formatted . Surely far simpler that writing the message directly using HTML tags and somewhat simpler for simple formatting than Markdown. That was the first “acid test”. But what about simplicity with coding of a Meltdown to HTML parser for a 201 level student ? The conclusion is that a Meltdown parser for most functionality is easy to code but some functionality is a little more complex when trying to “dot the Is and cross the Ts”.

Blazor-IoT : An Azure IoT Bridge via Blazor October 16, 2021 17:29 David Jones MVP iot iot iothub blazor rpi azure csharp arduino A Blazor app that acts as a go-between an IoT Device and Azure IoT Hub. Blazor receives telemetry from a device over Http which it then forwards to teh IoT Hub. Commands can be forwarded back to the device from the hub via the Blazor app. There is also a command line app that can get telemetry over a serial port and forward this to Blazor. This has been implemented for Arduino devices that have no WiFi/Ethernet. The take-homes are tha the devices don’t need to store hub credentials nor implement the Azure IoT Device SDK, and simple devices don’t need networking to be able to submit telemetry.

ClickOnce Hosting on Azure March 21, 2019 16:06 David Jones MVP appdev appdev visualstudio clickonce bobstorage I’ve often thought that it would be useful to make an app install available for GitHub projects that developers can run to test if they want to look into the project code.

You can easily use a custom domain to point the static site’s Azure URL. Also, Azure CDN enables the TLS protocol (aka SSLs) for a custom domain without having to get an external SSL certificate.

Introduction : What is this sequence of posts about? September 02, 2018 11:12 David Jones MVP xam uwp xforms sqlite uwp csharp OK so you have been creating Windows apps for ages including UWP. You have developed apps that run on the Windows desktop and the phone. You understand the rudiments of developing a modern UI app MVM etc. You understand PEM, properties events and methods for classes and GUI elements. You understand database CRUD can attach a database to an app using formal database invocation methods. You might even have mastered the Entity Framework and/or have a deep understanding of ORM. Overall, in coding terms, when confronted with a new programming context you know what you want to do and how you do with UWP or Windows Forms; you just need to do it in the new context.
