Delphi: this version does not support command-line compiling (yes, it does)
—
in DelphiThere are a couple of rare cases where I do an automatic build of a Delphi application from a batch file. This uses the dcc32.exe command-line compiler. This worked great on one machine, but today it failed on another machine that had an identical setup. The error message was: _PasCoreCompile: This version of the product…

Work faster in Delphi XE8 by using Castalia’s keyboard shortcuts
—
in DelphiThe new Delphi XE8 includes Castalia for easier code navigation and refactorings. The Castalia refactorings however are still separate from the ‘native Delphi’ refactorings and they partly overlap in functionality. They both have their pros and cons. A definite pro for Castalia is that most of the refactorings can be done ‘inline’, that is, there…

Delphi XE8 released, introduces Package Manager
—
in DelphiEarlier I wrote about the new Delphi roadmap and mentioned some features I considered interesting for the upcoming XE8 version. Today, Delphi XE8 was released and in the New Features list, another one caught my eye that I think is potentionally even more promising: the GetIt Package Manager. Every time a new Delphi version is…

New Delphi roadmap shows IDE and VCL enhancements (next to all the iOS, Android and IoT goodies…)
—
in DelphiBrian Alexakis has recently published some slides outlining the Delphi (and RAD studio) roadmap. I consider it very good news that, next to all the iOS, Android, Internet-of-things and other hot technologies, there are also some important VCL enhancements on there. Next to IDE feature and stability improvements, which are always nice of course. Take…

Bad Delphi upgrade experience (that was partly my own fault)
—
in DelphiLatest update (11:45): I finally managed to install Update 1. Though I still think the update experience is not as smooth as it could be (most of the points I mention below are still valid), and the error message I was getting was in no way related to what was actually wrong, the original fault…

Check your compiler warnings and hints. They may still be errors.
—
in DelphiI try to follow a zero hints and warnings policy for my code. (I admit I don’t always succeed though. 😉 ) But I was initially confused on how to solve this, and because of that learned something about not always following directions blindly… See this example code. This function should return true if everything…

Free up space on your OS disk by moving the Delphi XE6 installer files elsewhere
I noticed the free space on my SSD was getting smaller. Searching for ways to clean up a bit I discovered a ± 10 Gb hidden folder under c:\users\(account)\appdata\local\(guid). Inspecting its contents, it turned out to belong to the RAD Studio XE6 installer. No need to delete them, but I didn’t want them to take…

Solving I/O Error 103 in LoadXMLDocument
—
in DelphiIn a Delphi console application that reads its configuration from an XML file, I unexpectedly ran into “I/O error 103”. I/O error 103 will look familiar to most of you Delphi developers, it means “File not open”. I traced it to this source line: xmlcfg := LoadXMLDocument(FConfigFilePath); LoadXMLDocument comes from the Delphi unit XMLDoc.pas, so…

Returning to previous editor tab in Delphi
—
in DelphiHaving done a lot of Visual Studio work lately, I’ve grown accustomed to the VS way of switching between open file tabs with the Ctrl+Tab keystroke: it switches between files in Most Recently Used order, the same way Alt+Tab does for open programs. This is extra easy when, while coding, you have to do a…

Keeping a modeless window accessible from a modal (dialog) window
—
In a C# WinForms application I was working on, users were effectively working with two more or less independent windows: one they worked in, and another that showed documents and other info they need to do that work. The problem was that when they were in a dialog, for example one to assist in creating…
