Workaround: TActionManager broken in Delphi 10.3.3

Published on

UPDATE 2019-12-16: Official patch available.

Unfortunately, the long-awaited Delphi 10.3.3 release also brought a few new issues. One of them is that TActionManager is broken in a way, that prevents projects, using it, from compiling.

Because of some scope issue, the IDE keeps adding a unit named „IDETheme.ActnCtrls.pas“ to any form unit, that contains a TActionManager, once you save that form unit. „IDETheme.ActnCtrls“ is invalid, does not exist, thus the whole project will not compile anymore.

Fortunately, until EMBT releases a hotfix, there is a relatively easy workaround:

  • Add „VCL.ActnCtrls“ to any affected form unit
  • Create and add a completely empty unit to your project and name that unit „IDETheme.ActnCtrls.pas“
  • Compile

Publishing Delphi Apps to the Microsoft Store Episode 2

As promised my first video tutorial about the Microsoft Store, here are some additional steps I would like to share with you:

  • Publishing 32 & 64-bit packages
  • Version numbers
  • MS really reads Privacy URLs 🙂

This is the link to version 1.0.1 of HashExpert.

From REST to Database

Published on

There are frequently questions about how to get the results of a REST query (JSON) into a database table. This can of course be done manually, by using the „while not EOF do“ approach, but there are actually components in Delphi that make this job relatively easy and flexible.

So I created a video, demonstrating how to take the JSON response of a REST request and insert it into a database table.

I am using TFDMemTable, TFDQuery, and TFDBatchmove to move the data from the original TRESTResponse into an SQLite table – just by using FireDAC components.

Source code is available on BitBucket.

Publishing Delphi Apps to the Microsoft Store

Published on

In this video, I will guide you through the steps to get your Delphi app published in Microsoft’s App Store. For this demonstration, I will use a Firemonkey app, but technically the same thing would work with VCL apps as well.

This is the appx that I published and got certified by Microsoft. It’s a simple Hash calculator. Nothing too fancy, but useful enough to successfully pass Microsoft’s verification procedures: Microsoft Store – HashExpert

CData: Connecting to WordPress from Delphi

Published on

In this episode of my „Delphi Quick Thoughts“ series, I am demonstrating how to connect to a WordPress site from Delphi. I am using CData’s WordPress Enterprise connector for that.

https://www.cdata.com/firedac/

CData has more than one hundred „Enterprise Connectors“ that connect to almost every data source, that you can imagine: SAP, Twillio, WordPress, ActiveDirectory, SalesForce – just to name a few. These Connectors are implemented as FireDAC drivers. In other words, you can talk to all of these data sources by using SQL Queries and/or Stored Procedures, you don’t have to learn new syntaxes and components but just check the available schema and methods.

For WordPress, for example, check the docs here:
http://cdn.cdata.com/help/FWE/fire/pg_connectingtowordpresswebdesktop.htm

You can download the sources that I used in the video here.
Note: I left the app id and secret in the sources for your references but changed them on my server, so the app won’t be able to connect to my server anymore. You will need your own WordPress instance that is.

4. Deutsche Coderage 26.06.2019 – TMessage vs. MessageDlg

Published on

Am 26.06.2019 fand eine weitere Ausgabe der Deutschen CodeRage als Online-Konferenz statt.

Mein Beitrag, der um 17:00 MESZ zu sehen war, behandelt das das Thema TMessage und TMessageDlg: Wie triggert man aus Businesslogik Benutzerabfragen ohne sich an die UI zu koppeln?

TMessage vs MessageDlg

Weiterhin gibt es noch zahlreiche interessante Beiträge meiner Kollegen Matthias Eißing, Dr. Holger Flick, Volker Hillmann, Frank Lauter, Olaf Monien, Uwe Raabe, Bernd Ua und Daniel Wolf.

Die Anmeldung, der Zeitplan und weitere Informationen finden sich auf der CodeRage Seite.

Hier der gezeigte Quelltext, erweitert noch um eine TMessage, die ein einfaches ShowMessage anfordern kann.
Das Video ist auf meinem Youtube-Kanal zu finden.

Delphi CE Bootcamp 2018: Threading and Performance Tuning

Published on

Last week I had my „Threading and Performance Tuning“ lecture at Embarcadero Academy. It was an interesting experience and it looks like I’ll be using that platform for more courseware in the near future.

So if you are interested in how to work with TThread and TTask in Delphi, then feel free to checkout my lecture at Embarcadero Academy.

Below is the replay of the live Q&A session, which is a good teaser on what to expect in the full lecture. (The sound is a little bit flakey, as it was recorded live. The actual lectures have better sound)
