What makes you think so?

Or you try a total different approach described in this article: Dataset Enumerator Reloaded The old repository can be found on GitHub: https://github.com/UweRaabe/DataSetEnumerator, although the current development happens in https://github.com/UweRaabe/CmonLib Taking your code example from above: var LTotal: Double; LField1: TField; LField2: TField; LField3: TField; LField4: TField; begin LField1 := Query.FieldByName('FIELD1'); LField2 := Query.FieldByName('FIELD1'); LField3 := Query.FieldByName('FIELD1'); LField4 := Query.FieldByName('FIELD1'); Query.First; while not Query.Eof do begin LTotal := LTotal + LField1.AsFloat; // More stuff done with local field variables... Query.Next; end; a corresponding solution based on my unit could look like this: uses Cmon.DataSetHelper; type [DBFields(mapAuto)] // make sure record fields are named similar to DB fields! TMyFields = record Field1: Double; Field2: Double; Field3: Double; Field4: Double; end; var LTotal: Double; begin LTotal := 0; for var rec in Query.Records<TMyFields> do begin LTotal := LTotal + rec.Field1; // More stuff done with rec end;

There is no Delphi 12 Update 1 (yet), only Delphi 12 with Patch 1. During times a common rule had established to wait for the first Update after an initial release before starting to use a Delphi version in production. That doesn't imply not to install and start using it - just not for production. JM2C

This will only change the TField array item, but not the local variable FieldX as expected. A const or var array of TField is no replacement for a couple of var par: TField parameters. As soon as you construct that array parameter, the addresses of the local variables are gone, while their current content (which may be undefined here) is copied to the array item. Perhaps this may be a better approach (didn't try as I am too lazy to create a fake dataset with these fields): procedure ConnectFields(Query: TDataSet; const Fields: TArray<^TField>; const Names: TArray<string>); begin Assert(Length(Fields) = Length(Names), 'Number of fields and number of names must match'); for var ix := 0 to Length(Fields) - 1 do begin Fields[ix]^ := Query.FindField(Names[ix]); if not Assigned(Fields[ix]^) then raise Exception.Create(Format('Field %s not found.', [Names[ix]])); end; end; procedure Test; var Field1, Field2, Field3, Field4: TField; begin ConnectFields(Query, [ @Field1, @Field2, @Field3, @Field4], ['Field1', 'Field2', 'Field3', 'Field4']); ... end;

Isn't that what Shared Resources are for?

Actually there is a way to achieve that using generics: type TRecB<T> = record FieldA: T; FieldB: Integer; FieldC: string; end; type TRecA = record Secret: string; end; type TRecB = TRecB<TRecA>;

There is also a very old version on SourceForge: Rad Studio Code Examples Code

This is indeed very instable. One would need to extend the current internals significantly to make this work. Nevertheless one can achieve some results by setting AcceptExpressions to True and override these two methods: type TNumberBox = class(Vcl.NumberBox.TNumberBox) protected function GetValidCharSet(AAcceptExpressions: Boolean): TSysCharSet; override; function IsNumericText(const AText: string): Boolean; overload; override; end; function TNumberBox.GetValidCharSet(AAcceptExpressions: Boolean): TSysCharSet; begin Result := inherited GetValidCharSet(AAcceptExpressions); if Mode = nbmFloat then Result := Result + ['e', 'E', '+', '-']; end; function TNumberBox.IsNumericText(const AText: string): Boolean; begin Result := inherited; if AText.LastIndexOfAny(['e', 'E']) = AText.Length - 1 then Result := False; end;

You have already been told:

There is a reason why that is not supported: type TRecA = record; TRecB = record FieldA: TRecA; end; TRecA = record FieldB: TRecB; end;

The current Delphi 12 version doesn't support that out of the box.

SetThreadDpiAwarenessContext has to be wrapped around the creation of a top level window handle to work correctly. All child windows then inherit the context of the top level one. This rules out any docked forms or frames, which explains why it is not feasible for the Embedded Designer. (Fun fact: an undocked designer window would have worked with that.) A solution for this problem could be SetThreadDpiHostingBehavior and AFAIK that is something Embarcadero is investigating in.

As of today a rebuilt 11.3 web installer is available on my.embarcadero.com.

As of today there is a rebuild web installer for 11.3 available on my.embarcadero.com.

Sounds like it were a religion...

Maybe related to RSP-43625

Currently there is no GetIt server for 11.2! They are still working on it.

Then you seem to have Winapi.Windows.pas in your search path. Otherwise the compiler won't try to compile that issuing that error.

Question: Why are you compiling Winapi.Windows.pas in the first place?

They probably just had to be recompiled.

I am not aware of any.

I have issued a request to install the patch for All Users to fix these inconveniencies (it is a simple setting in the GetIt configuration). I hope someone will take care of that. Otherwise I have to wait for the new QP to get online.

GetIt creates a subkey in the registry under CatalogRepository for each installed item. It is probably there where the about dialog gets is information from, but I am only guessing. Another weird thing is, that another user or registry branch (with -t parameter) won't see the patch either - albeit being installed.

I am with Nigel here: That seems to be the best solution.

In contrast to CE do paid licenses come with access to the majority of previous versions.
