Implementing response tables without macros
In our Knowledge Base article "Windows Message Dispatch in OWLNext" there is now a new section on implementing response tables without macros. So if you have had enough of response table macros and want to write C++ instead, take a look.
Window procedures vs dialog box procedures
After having been tripped up by the Windows API documentation and the difference between window procedures and dialog box procedures, I have added a little helpful section to our Knowledge Base article "Windows Message Dispatch in OWLNext" describing the difference and how OWL in turn differs from classic Win32 programming in this regard.
TEdit demo
A new demo of various TEdit capabilities is added to the Classes project.
Some of the less commonly used capabilities that are demonstrated are:
- Automatically converting entered text to lower or upper case.
- Allowing only digits to be entered.
- Changing the default password character.
- Enabling Web Search in the edit box context menu.
- Multiline control with a formatting rectangle.
- Setting cue text in the edit box.
- Showing balloon tips in the edit box, for example when the text limit is reached.

C++ Coding Tip: Embrace the conditional operator
I just did a quick Internet search, and it seems to me that many are still preaching against the use of the conditional operator (a.k.a. "ternary operator"). However, after 30 years of C++ programming, I've come to love this operator, and I believe it is a fundamental programming expression for clean maintainable code.
Let's have a look. Which bar do you prefer?... read more
OWLNext 7.0.10 and 6.44.20 updates
These updates fix an initialisation issue in THdrItem [bugs:#546].
State of OWLNext — shifting gears to 8
Some of you may have noticed that the trunk, where our main OWLNext development happens, has recently changed to version 8 [r6254]. That may be curious, considering the 7 series is less than two years old, with only 7.0 and updates released, so far. Many of you are still using the 6 series, I suspect, which has gone on and on for over 20 years!... read more
OWLNext 7.0.9 and 6.44.19 updates
These updates fix a regression in 6.40: "WinMain fails to parse unquoted argument" [bugs:#541].
OWLMaker Build 6218 update
This update fixes a regression that caused OWLMaker to freeze for 10 seconds after a build [bugs:#540]. It also fixes another issue where aborting the build ("Tools | Stop build") aborts the build for all instances of the program, rather than just the one for which the command is issued. This can be an issue if you use multiple instances of OWLMaker to run builds concurrently for different toolsets and/or versions of the libraries. With the fix, multiple instances of OWLMaker can now abort builds independently.... read more

OWLMaker is now signed
For increased trust and security, the OWLMaker executable files are now signed. The secure digital signature is provided by Hasfjord Software AS.
As of today, the updated package ("OWLMaker.zip") passes all scans at VirusTotal. Previously, without a digital signature, the VirusTotal scan produced a spurious false positive ("Trojan.Malware.300983.susgen" detected by MaxSecure).... read more
OWLMaker Build 6194 update
This is a pretty big update. First and foremost, OWLMaker now includes optional automatic update checking as an extension to the existing manual update checking, which has itself been revamped and improved. The other big new feature is Unicode support in the built-in code editor. Apart from those big changes, OWLMaker is as always based on the latest fixes and features on the trunk, which for this version means it includes major UI improvements worked on for OWLNext 7.1, giving it a refreshed and modern flat look without the outdated 3D-style edges all over.... read more
