Setting the correct Xcode build number for Delphi FMX Apps

Olaf Monien – If your Xcode version updates (manually or by Apple’s updating mechanism) then make sure to re-import the iOS/macOS SDK from within Delphi.

Do not forget to add Export/Encryption exemption to your Delphi iOS apps

Firemonkey TMemo Scrolling

Olaf Monien – When you add lines to a TMemo in Delphi Applications, then you might want to scroll to the very end of that particular Memo, so that the newest lines are kept in view. In FireMonkey it’s as easy as just calling GoToTextEnd: You might notice though, that when you clear…Read More

MVVM Anwendungen mit Delphi und nicht gegen Delphi

Olaf Monien – Im folgenden Video meines Youtube-Kanals eine Einführung zum Thema MVVM Anwendungen mit Delphi. Wichtige Motivation ist für mich, dass ich soviel Delphi wie möglich verwende, also eben nicht anfange, alles von Hand im Source-Editor hinzuschreiben. Hinweis: Das Video versteht sich als erste ...

TTask / TThreadPool may keep interfaced objects alive

Olaf Monien – I am using TTask.Run quite a lot in projects and in many of my demos. I won’t go into the details of how to use TTask here, but I only want to highlight that there is still an open issue, which may cause interfaced objects to be destroyed much later, than…Read More

Sharing DataModules between VCL and FMX projects

Olaf Monien – When you start implementing cross-platform applications in Delphi’s FireMonkey framework, then you might consider reusing TDataMdoule instances from your existing VCL applications. If your code is clean enough, i.e. your DataModules are separated from any UI code, that is contain no references ...

Kommentar zu MVVM Anwendungen mit Delphi und nicht gegen Delphi von Michael

Olaf Monien – Zuerst einmal vielen Dank für den interessanten Vortrag. Wie würden in einem MVVM schreibende Prozesse realisiert werden, so dass Eingaben von mehreren Edits in die DB geschrieben werden? Der Verdrahtungsauswand im View soll ja minimal sein. Wie würde dann weiterhin Rückmeldungen in die View ...

Viewing logs on Android devices

Olaf Monien – On my previous post I mentioned how to generate a log entry from your Delphi app on Android devices: uses AndroidApi.Log; var LMarshaller: TMarshaller; begin LOGI(TMarshaller.AsAnsi(‘Hello World’).ToPointer) But how do you actually get hold of Android’s log output? You can view the log ...

Dealing with MarshalledAString

Olaf Monien – A couple of versions ago Delphi XE kind of silently introduced the new string types MarshalledString and MarshalledAString. These types basically map to PChar and PAnsiChar, which worked fine for years. Since Delphi went multi-platform though, there was the need to introduce some stricter ...

Delphi XE5 : SSL / HTTPS on different platforms with TIdHTTP and TRESTClient

Olaf Monien – Using SSL/HTTPS with Indy’s TIdHttp (or through TRESTClient – which is effectively based on TIdHttp) requires external OpenSSL libraries, which is something most of us probably learned in the past.
