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, sourceforge.net/p/radstudiodemos/code/HEAD/tree/branches always had the real product name as banch name.

On 20150817 this branch got added:

http://sourceforge.net/p/radstudiodemos/code/HEAD/tree/branches/RADStudio_Seattle/

Today, Horacio Filho who observed the Seattle part in the new documentation URL http://docwiki.embarcadero.com/Libraries/Seattle/en/Main_page 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 http://docwiki.embarcadero.com/Libraries/XE7/en/Main_Page will usually bring you to the most recent documentation http://docwiki.embarcadero.com/Libraries/en/Main_Page.

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

Installation

  1. Obtain 29458_firedac_xe4_update_2_for_rad_studio_delphi_c_ent_ult_arch.zip from a registered Delphi XE4 or higher license: http://cc.embarcadero.com/item/29458:
  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 http://support.embarcadero.com/article/42970:
  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]
Error

[Content]
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

Solution

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

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

This is especially useful when the block selection is stuck (this happens every now and then: it’s a known bug).

Jon Skeet’s speech “Back to basics” is really a good watch – via Jørn Einar Angeltveit G+

Posted by jpluimers on 2015/07/15

Thanks [Wayback] Jørn Einar Angeltveit for sharing this a while ago:

A session by Jon Skeet and Tony the Pony (which has strong teeth) presented during the Polish DevDay 2013 in Kraków, Poland.

[Wayback] +Jon Skeet’s speech [Wayback] “Back to basics” is really a good watch.

In a funny way, he explains why the simplest fundamentals of computer software text, dates and numbers can cause some real headache for the programmer…

In case you didn’t know: Jon Skeet is “Chuck Norris” on [Wayback] stackoverflow.com:

The subtitle is “the mess we’ve made of our fundamental data types”.

Some of the topics covered:

20 resources on migrating to Unicode with Delphi | Software on a String

Posted by jpluimers on 2015/07/08

Great post by Marjan Venema when you need to migrate your old Delphi programs to the modern Delphi world: [Wayback] 20 resources on migrating to Unicode with Delphi | Software on a String.

I’m glad that some of the links overlap with what I posted and presented in the past at:

Well done Marjan!

Windows Kernel object names are optional. Don’t give them a name unless you intend them to be shared. (via: The Old New Thing)

Very interesting:

Kernel object names are optional. Don’t give them a name unless you intend them to be shared.

via: [WayBack] You can name your car, and you can name your kernel objects, but there is a qualitative difference between the two – The Old New Thing – Site Home – MSDN Blogs.
