I just had the need for a safer version of Delphi's GetEnumName, which checks whether the enum value passed to it is actually valid. This is what I came up with: [delphi] // P must point to the length field (that is the first byte) of a ShortString function AfterShortString(const P: Pointer): Pointer; inline; begin … Continue reading SafeGetEnumName a safer implementation of TypInfo.GetEnumName

dzBdsLauncher 1.0.13 released
I just released dzBdsLauncher 1.0.13. If it detects more than one possible Delphi version from the available project information it now checks which of them are installed if only one is installed, it starts this version. If more than one is installed, it asks the user.
dzBdsLauncher 1.0.12 released
I just released dzBdsLauncher 1.0.12. It now shows an error message, if it is called with a .dpr file parameter but cannot find a corresponding .dproj, .bdsproj or .dof file.
I was wrong, again
In my previous post An improved Abstract Error Handler for Delphi I claimed there was a change in the Delphi RTL between Delphi 10.1 and 10.2. I have no idea why my tests looked like that was the case. Maybe a stale dcu file somewhere? In fact the change was made between Delphi XE and … Continue reading I was wrong, again
An improved Abstract Error Handler for Delphi
NOTE: The original blog post was wrong in one point: The change happened in Delphi XE2, not 10.2. I have now updated this and also adapted the conditional compilation in u_dzAbstractHandler. I should also mention, that the code only works on Win32. Win64 and other platforms are not supported. But since that unit won't compile … Continue reading An improved Abstract Error Handler for Delphi
Switching GetIt to Online mode for an alternate Delphi configuration
GetIt is the package manager built into the Delphi IDE. It can be used in Online and Offline mode. If you installed Delphi from an ISO, GetIt was left in Offline mode. That has some drawbacks: GetIt cannot notify you about new updates or patches as they become available. The "Manage Features" functionality of the … Continue reading Switching GetIt to Online mode for an alternate Delphi configuration
Many highDPI releated bugs in GExperts fixed
I have spent several days now to try and fix the remaining bugs in GExperts that are related to highDPI. I think I nailed most of them but unfortunately I can't be sure because the possible combinations of monitors and their arrangement and settings is so large. So, if you would like to help out, … Continue reading Many highDPI releated bugs in GExperts fixed
New Embarcadero Quality portal – new hope
Embarcadero has released Delphi 12.1 and at the same time opened their new Quality Portal. I have now spent more than an hour reproducing, documenting and reporting several long-standing bugs, some of which have been around since Delphi 11. Here are the links to my bug reports, if anyone wants to take a look (voting … Continue reading New Embarcadero Quality portal – new hope
Universal Debug Visualizer for Delphi
As mentioned in my previous post on dzDebugVisualizer I was thinking about writing a generalized debug visualizer which can be user-configured to register itself for any data type. Well, that debug visualizer now exists. It's part of dzDebugVisualizer and called "Universal Visualizer for Delphi". It has got a configuration page in the Tools -> Options … Continue reading Universal Debug Visualizer for Delphi
Simplified Debug Visualizers for all my TNullableTypes
After playing around with debug visualizers, I found that there is a very simple way to provide a visualiser for many record types: Just add a special method (I called it Dump) to those records that returns a string that you can then evaluate in the debugger and display in the debug windows. There are … Continue reading Simplified Debug Visualizers for all my TNullableTypes
