Max Schrems on Twitter: “WTF?! So the “solution” of #Facebook, #Goolge or #Microsoft for #GDPR is to claim they have a “legitimate interest” to take all the data they can get their hands on and use it for any of their “products” (incl. ads)… 😧😭 #BeggingForThe4Percent”

dzComputerInfo: a small tool that shows a window on top of all other windows displaying the computer name and currently logged on user.

Posted by jpluimers on 2018/05/18

Interesting as bgInfo does not support top most windows or overlay: it only does the Desktop background, and you need to go through hoops to recreate the background on each logon:

Enter dzComputerInfo. It’s a small tool that I wrote the evening after the above incident which does exactly one thing: It shows a window on top of all other windows displaying the computer name and currently logged on user. Since the window is so small and it places itself automatically just above the start button, it does not really become a nuisance.

The tool and the source code is available from sourceforge, if anybody else thinks he has a use for it.

The G+ thread also the interesting comment by Gaurav Kale:

The Classic Shell Start button supports environment variables in its tooltip. So just specify: %username% on %computername% for the Setting called “Button Tooltip”. Then to see the currently logged on user and computer name, you just have to HOVER over the Start button!

GDPR for database professionals and DBAs. Poster.

Posted by jpluimers on 2018/05/17

A poster showing how to prepare your Oracle database for GDPR. Wait for the email download link by visiting GDPR for database professionals and DBAs. Poster (they mention to be GDPR compliant in [WayBack] their policy), or look at the WayBack machine to download it now.

One takeaway for me: you also need to scrub backups when removing someone your records.

Delphi: a pattern for a generic factory, this one for components, but can be uses for anything having a base class like a TThread descendant.

Posted by jpluimers on 2018/05/16

Generics and constraints in Delphi is still a bit of pain.

A while ago, I needed a factory for threads. It was more convoluted than I meant it to be, so I had a short chat with Stefan Glienke.

He came up with an example similar to the one below. I tore it apart so you can on each line see what the compiler dislikes.

This fails, but was kind of how I wanted it to be:

type
   TFactory = record
     class function Manufacture<T: TBaseClass, constructor>(parameter definitions): T;
   end;

class function Manufacture<T: TBaseClass, constructor>(parameter definitions): T;
begin
  Result := T.Create(parameter values);
end;

Which means I need to update Delphi Constraints in Generics – RAD Studio XE documentation wiki

The factory:

type
  TComponentFactory = class
    class function CreateComponent<T: TComponent>(AOwner: TComponent): T; static;
  end;

class function TComponentFactory.CreateComponent<T>(AOwner: TComponent): T;
var
  ComponentClass: TComponentClass;
  Component: TComponent;
begin
  ComponentClass := T;
  Component := ComponentClass.Create(AOwner); // you can't do `T.Create(AOwner)`
  Result := T(Component); // you can't do `Result := ComponentClass.Create(AOwner);`
end;

The usage:

var
  Component: TButton;
  Owner: TComponent;
begin
  Owner := Application.MainForm;
  Component := TComponentFactory<TButton>.CreateComponent(Owner);
  Component.Parent := Owner;
end;

Full source example is at: After a discussion with Stefan Glienke: a pattern for a factory, this one for components, but can be uses for anything having a base class like a TThread descendant.

In the mean time, Spring4D has added the [Archive.is] Spring4D: TActivator record with many CreateInstance methods that allow you to create instances of classes for which you just have type information.

This fails:

type
   TFactory = record
     class function Manufacture<T: TBaseClass, constructor>(parameter definitions): T;
   end;

class function Manufacture<T: TBaseClass, constructor>(parameter definitions): T;
begin
  Result := T.Create(parameter values);
end;

Delphi WSDL default importer settings

Posted by jpluimers on 2018/05/15

Note to self (as the WSDL importer has trouble with WSDL files that include XSD files having xsd:group definitions), the default settings of the importer in the UI:

-Oa -Od -Oe -Of -Oh -Oi -Oj -Oo -Op -Ot -Ou -Ov -Ox

This matches the output from the WSDLImp.exe default settings as well (larger screenshots below):

I suspect the reason is that the command-line importer does, but the wizard does not, show an exception during processing:

*Error*: D:\Playground\iECK DT2.0 services v2.1.1\xsd\ECK-DT2-CatalogServiceSchema-v2.1.1.xsd
> Access violation at address 0059DBA4 in module 'WSDLImp.exe'. Read of address 00000000
Done : D:\Playground\iECK DT2.0 services v2.1.1\wsdl\ECK-DT2-CatalogService-v2.1.1.wsdl>0
Writing: D:\Playground\iECK_ImportWSDL\ECK_DT2_CatalogService_v2.pas

Hopefully more on that later.

Both the IDE expert and console based WSDLimp will write the output .pas file and the output file of both tools has the same content.
