The Unicode issues in GExperts just don't end. Today I fixed three of them: [delphi] procedure bla; begin SomeVar := 3245; // german description with some äöüß to SomeVar SomeVar := 123; SomeQuery.FieldByName('GermanWordWithäöüß').AsString := 'some value'; end; [/delphi] (Yes, I know, this doesn't compile.) Move the cursor to the first occurrence of SomeVar and press … Continue reading GExperts Bugfixes

Delphi XE2 crash when opening the About dialog
Today I had a rather annoying problem with Delphi XE2. I only wanted to change the caption of a TListView column using the Columns Editor (right click -> Columns Editor). The IDE crashed on me with an Access Violation. So, I thought I had broken it again (things like this happen when you are developing … Continue reading Delphi XE2 crash when opening the About dialog

Weihnachtslieder Spickzettel
Es ist jedes Jahr dasselbe, es soll vor der Bescherung gesungen werden und nur wenige kennen den Text. Irgendwie schon peinlich. Deshalb habe ich jetzt endlich eine Maßnahme ergriffen und mir den Text der gebräuchlichsten Lieder zusammengestellt.

TdzStreamCache class for caching access to any TStream

Some of them were programming related and one of these was writing a caching class wrapper for TStream descendants (e.g. … Continue reading TdzStreamCache class for caching access to any TStream
Find all subdirectories containing xml files on Linux command line
So I don't forget: The following Linux command shows a list of all subdirectories that contain a least one *.xml file: find . -type f -name '*.xml' | sed -r 's|/[^/]+$||' | sort | uniq This finds all xml files where the extension is all lower case. But since many Windows programs upper case it … Continue reading Find all subdirectories containing xml files on Linux command line
Using PE Flags in Delphi
There was a discussion about using the PE flag IMAGE_FILE_LARGE_ADDRESS_AWARE and whether this is equivalent to compiling a program to 64 bit Windows target (no it's not) in the German Delphi Praxis forum. This prompted me to have a look at what kind of flags can be specified and how to do that for a … Continue reading Using PE Flags in Delphi
Advanced Records in Lazarus / fpc
Note to self: Delphi's Advanced Records are also available in Lazarus / Free Pascal, but only if they have been explicitly enabled with the modeswitch compiler directive: [delphi] unit SomeUnit; {$mode objfpc}{$H+}{$modeswitch advancedrecords} interface type TSomeRecord = record FSomeField: integer; function SomeMethod: integer; end; implementation function TSomeRecord.SomeMethod: integer; begin Result := FSomeField; end; end. [/delphi] … Continue reading Advanced Records in Lazarus / fpc
