bash – cheatsheet to choose between ; or && or || or & via Ask Ubuntu
Posted by jpluimers on 2017/02/26
Cheatsheet:
A; B Run A and then B, regardless of success of A A && B Run B if A succeeded A || B Run B if A failed A & Run A in background.
Source: bash – Which one is better: using ; or && to execute multiple commands in one line? – Ask Ubuntu [WayBack]
Thanks Jack [WayBack] for the initial answer ubfan1 [WayBack] for getting the formulation right, Hatshepsut [WayBack] for making it a readable cheat-sheet and leftaroundabout [WayBack] for making this brilliant addition using parenthesis which can be used for all permutations:
(A && B) & In the background: run B if A succeeded

Delphi sorcery: Generics, modules and typeinfo
Posted by jpluimers on 2017/02/23
the release of 1.2 is almost there! We are working hard to deliver it shortly after the next Delphi release which will happen … soonish, I think. ;)
The release/1.2 branch has been around for a while – please take a look if you haven’t already. It contains a lot of new features and bugfixes. I will tell you more about some of the amazing features next time which won’t take as long as it took since the last blog post – promise. :)
Apart from a very interesting take on DI resolvers, the above great info too!
Please take a look at spring4d/branch/release/1.2 as it has been very stable for quite some time.

Delphi, resource files and includes – some links
Posted by jpluimers on 2017/02/23
Some links that were useful getting back into using Delphi with resource scripts and include files:
- delphi – Include file behave differently using RC.EXE or BRCC32.EXE to build *.rc files – Stack Overflow [WayBack]
- About Resource Files (Windows) [WayBack]
- #include (Windows) [WayBack]
- Preprocessor Operators (Windows) [WayBack]
- Pragma Directives (Windows) [WayBack]
- BRCC32.EXE, the Resource Compiler – RAD Studio [WayBack]
- null terminate your versioninfo strings [WayBack]
- resources – How to compile Delphi RES file from commandline – Stack Overflow [WayBack]
- Using resource files with Delphi – DelphiBasics [WayBack]
- delphi – Remove {$R *.res} in package.dpk file will remove the rccompile in .dproj file – Stack Overflow [WayBack]
- delphi – What Is a .vrc file, how is is generated and can you remove it using the IDE? – Stack Overflow [WayBack]
- TN035: Using Multiple Resource Files and Header Files with Visual C++ [WayBack]
- Resource Files (Visual Studio) [WayBack]
- Include resource files in your Delphi build process Ondrej Kelle – Google+ [WayBack]
- Sometimes a unit only includes a .res file but ships with a .rc file, then you need to run BRCC32 on it (either manually once of build a build script); example: One of my favorite features in the XE IDE is an add in, part of Version Insight, that does Live Blaming … – Nick Hodges – Google+ [WayBack]
Maybe I should have considered this alternative:
- twm’s homepage – dzPrepBuild for Delphi (English) [WayBack] -> sf.net dzPrepBuild for Delphi / Home / Home

PS: a first go on a resource file structure for Version Information is below.

Windows 10 – language neutral batch file to start Windows Update
Posted by jpluimers on 2017/02/22
A while ago, I bitched that Microsoft moved away the Windows Update out of the Control panel into a language depended place (in Windows 10 1511 update broke the Hyper-V networking – Fix network connection issues).
Since then I had to maintain too many locales running Windows 10. So here is the batch file:
for /f "delims=" %%A in ('PowerShell -Command "(Get-Culture).Name"') do explorer "%LocalAppData%\Packages\windows.immersivecontrolpanel_cw5n1h2txyewy\LocalState\Indexed\Settings\%%A\AAA_SystemSettings_MusUpdate_UpdateActionButton.settingcontent-ms"
It uses these tricks:
- Set output of a command as a variable (in this case a for loop variable)
- Execute PowerShell script in a .bat file
- PowerShell Get-Culture (which gets a .NET CultureInfo instance)
- CultureInfo.Name property (which has the nl-NL, en-US, etc codes in it)
It replaced this simple batch-file which has worked for like 10 years:
%windir%\System32\rundll32.exe url.dll,FileProtocolHandler wuapp.exe

Delphi and stuff: The strange limitation of 64 threads
Posted by jpluimers on 2017/02/21
… there’s no need to use WaitForMultipleObjects in Step 2. It’s fairly easy to keep a counter of active threads in the pool (interlocked-incremented when a thread starts, interlocked-decremented when a thread is finished). When the counter reaches zero (no more active threads), signal an event. With only one event to wait for, you can use WaitForSingleObject…
So no more 64-thread (MAXIMUM_WAIT_OBJECTS) limits for pools…

“Just a couple of bugfixes”, but one is very important to me: [WayBack] double clicking on a test-result now doesn’t freeze the IDE and brings you to the right source code line.

It would be so cool if a fix fills in the %s with the invalid file name.
