New Delphi product version: will it be Seattle or 10? It might be both! radstudiodemos/code/…/branches now has RADStudio_Seattle branch, docwiki URLs with Seattle exists and nice YouTube preview image!

Posted by jpluimers on 2015/08/30

Two recent observations: that lead me into thinking Embarcadero is changing the Delphi and RAD Studio version suffix to Seattle.

Thanks to Achim Kalwa for getting that to my attention in Looks like Delphi XE9 will have support for Windows 10 RT: …

It led me to my observation that until now, always had the real product name as banch name.

On 20150817 this branch got added:

Today, Horacio Filho who observed the Seattle part in the new documentation URL which currently is only accessible only for the groups writer, l10n, RADBeta, ConnectBeta, Employee.

The docwiki URLs historically also use the real product names in the URL.

In fact there is a little trick: removing the product name portion of a docwiki URL usually brings you to the most recent documentation (which might be more up to date and provide more information even for older products). So removing the XE7/ part of will usually bring you to the most recent documentation

If they both Seattle URLs still use product names, then the new Delphi version is called Seattle is added.

Installing FireDAC 8 for Delpi 2007

Posted by jpluimers on 2015/08/19

Installing FireDAC 8 for Delpi 2007


  1. Obtain from a registered Delphi XE4 or higher license:
  2. Extract it into FireDAC_8.0.5.3365.exe.
  3. Run FireDAC_8.0.5.3365.exe with the /showide parameter as described in
  4. FireDAC_8.0.5.3365.exe /showide
    1. (When not running as Administrator: elevate to Administrator)
    2. Welcome screen: press next
    3. License screen: accept, then press next
    4. Destination selection screen: keep C:\Program Files (x86)\Embarcadero\FireDAC, then press next
    5. Select components screen: keep the selection (Full installation), then press next
    6. Select IDEs screen: choose Delphi 2007 (but not Delphi 2006), then press next
    7. Select Demo Databases screen: keep the settings (do not choose Interbase / Firebird server as then you have to provide the credentials for the server), then press next
    8. Start menu screen: keep Embarcadero FireDAC, then press next
    9. Ready to install screen: press install
    10. After installation: press finish, then read the readme
      1. or later browse to <file:///C:/Program%20Files%20(x86)/Embarcadero/FireDAC/Readme.html>
      2. That’s what actually tells you:

The installer automatically installs FireDAC in the Delphi XE4 and C++ Builder XE4 IDEs. For older versions of the IDEs, you can run the installer with the /SHOWIDE command line parameter.

After installation

To fix this when starting Delphi:

[Window Title]

Can't load package C:\Users\Public\Documents\RAD Studio\5.0\Bpl\AnyDAC_Dcl_D11.bpl.
The specified module could not be found.
Do you want to attempt to load this package the next time a project is loaded?

[Yes] [No]

The actual BPL sometimes is in C:\Users\<username>\AppData\Local\Documents\RAD Studio\5.0\Bpl\AnyDAC_Dcl_D11.bpl

The cause is that the BPL gets loaded from %BDSCOMMONDIR% which on some systems points to

  • %PUBLIC%\Documents\RAD Studio\5.0

and on others points to

  • %LOCALAPPDATA%\Documents\RAD Studio\5.0

This seems to be the case on machines where more different Windows users are using Delphi.

The installer does not fully recognize this distinction, so copies the BPL to %LOCALAPPDATA%\Documents\RAD Studio\5.0\Bpl and registers it as being in %PUBLIC%\Documents\RAD Studio\5.0\Bpl.

On these machines there is a difference between the definition of BDSCOMMONDIR in these registry keys:

  • HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment
    • points to C:\Users\Public\Documents\RAD Studio\5.0
  • HKEY_CURRENT_USER\Environment
    • points to C:\Users\<username>\AppData\Local\Documents\RAD Studio\5.0


reg delete "HKCU\Software\Borland\BDS\5.0\Known Packages" /v "%PUBLIC%\Documents\RAD Studio\5.0\Bpl\AnyDAC_Dcl_D11.bpl" /f
reg add "HKCU\Software\Borland\BDS\5.0\Known Packages" /v "%BDSCOMMONDIR%\Bpl\AnyDAC_Dcl_D11.bpl" /t REG_SZ /d "Embarcadero FireDAC Components" /f

Fuzzing in addition to Unit Tests – via: David Millington G+

Posted by jpluimers on 2015/08/11

I need to give this link from Jonathan Lange which was shared by David Millington some thought:

Embedded in Academia : How to Fuzz an ADT Implementation.

There they add fuzzers to help testing an ADT: in this case an Abstract Data Type in the form of  a red-black tree.

And then see if it can be added to DUnit and NUnit or MSTest/VSTest in some way.

In the original post by Jonathan Lange, an important remark was made by Eric Castelijn:

… the downside being that having non deterministic tests means having test failures that are hard to repeat

When fuzzing multiple or composite values, the chances that you will hit interesting edge cases semi-reliably will drop dramatically, in my experience


via “This post has two points. First, you should write ADT fuzzers. It is often….

Delphi: turn off column or line block selection mode – via: Default IDE Shortcut Keys; Delphi Programming

Posted by jpluimers on 2015/07/30

The Default IDE Shortcut Keys – Delphi Programming was a good starting point to find out how to disable column or line blocks.

Since the table there is incomplete (even the Embarcadero documentation is wrong as some shortcuts can turn on and off a mode), here are the relevant shortcuts keys:

Ctrl + O + C Turns on/off blockcolumn selection mode Delphi 5 and up
Ctrl + O + K Turns on/off block selection mode Delphi 5 and up
Ctrl + O + L Selects current line (and turns off block selection mode) Delphi 5 and up
