It is not possible if you want to design the forms. The IDE will show only the visual design for one form. 1 pas + 1 dfm is the limit.

You can have multiple forms with the limitation that you create the components on the form in the code.

You should try these steps to report the bug using the e-mail to protect the source code you are working on: https://docwiki.embarcadero.com/RADStudio/Athens/en/Troubleshooting:_Delphi_LSP.

Something is blocking the file(s) from writing. Check out for viruses and settings in applications that could lock the file, is it a shared folder? First step could be to add the folder to the antivrus exception folders lists to keep it locking the files there.

Are you talking for Aggregates in general, or my example of use?

in general, when using with you can never sure to which object you are assigning a value. It can work in one version of Delphi and break in the next one. You can always write:

var
  a: TFDAggregate;
begin
  if Qry.Aggregates.Count = 0 then
  begin
     a:=Qry.Aggregates.Add;
     a.Expression := 'COUNT(Town)';
     a.Active := True;
     a.Name:='NoName';
     Qry.AggregatesActive := true;
  end;
end;

First of all do not use with it is always a bad idea.

You are not setting the name property for the aggregate object.

Edit. I have checked even the examples on docwiki are wrong. 

You can send the query as a parameter to the function that generates the XML.

It's probably done on the commit comment with an internal ticket number. No reason to put it in the source file on the comment visible by the public (= us).

Most probably yes. It would be easier if we could get that information. I do hate when on codebase I am working on changes like this does not have a comment with a proper description or ticket number. Searching in repository for the specific change can be time consuming.

Maybe it is commented out to fix some strange issue/bug.  In that case the developer that has commented out the code should include the report number in the comment to document the change in behavior.

And because Delphi is still 32

You can try the test 64 bit Delphi IDE.

Same on my system 2 different exe files.

It could be that when the library detects the debugger it slows down. You can try using Lazarus at Windows to see if it behaves the same.

But you are still blocking, if looping around a wait.
Are you going to put a ProcessMessages in that loop?

The question was whether it is possible to check if the future is completed or not. Method Wait can be used to achieve that. (The design of wait could be improved to support non-blocking call, but we can argue if a couple of ms delay is significant or not.) 

Nobody mentioned that the future is going to be used in the main thread. Whenever ProcessMessages should be used or process paint messages depends on how long the calculation should take. If it is under a minute or the application should be blocked during the life of the method, it should not be used.

Wait = Block. 

Read the documentation:

function Wait(Timeout: Cardinal = INFINITE): Boolean; overload;

You do not have to wait for infinite.

here is no callback in tfuture to use unless monitoring her status with while loop which also freeze the app

That is the idea behind future to do something until you definitely need the result of the future. If you want to check if the future is finished you can use the wait method.

The answer is the same as for the previous question you have to change the StyledSettings. In this case you are changing the Family and Style thus you have to remove those elements from the set, you do not change the Style of the font.

You can replace:

L1.StyledSettings:=L1.StyledSettings-[TStyledSetting.Style];
L2.StyledSettings:=L2.StyledSettings-[TStyledSetting.Style];

with:

                          L1.StyledSettings:=[];
                          L2.StyledSettings:=[];
 

Calling a method of the target form?

But a dataset like DBGrid or client dataset is caching the calculated field values, right?

First of all, DBGrid is not a dataset, it is a component that displays data. How should a component know if and when the field value must be calculated again and cannot use the cached value?

On the other hand you can use fkInternalCalc  (caches) stores the calculated values https://docwiki.embarcadero.com/Libraries/Athens/en/Data.DB.TFieldKind.
 

CaretPositionProp is not nil, however when invoking the GetValyue in CaretPositionProp.GetValue self is an Inaccessible value:

FMX.Memo.TCustomMemo.GetCaretPosition
:00cfcac8 RawInvoke + $40
System.Rtti.RawInvoke(???,???)
:00cfcead Invoke + $249
System.Rtti.Invoke(nil,(),???,???,True,True)
:00cf5689 TRttiInstanceProperty.DoGetValue + $DD
System.Rtti.TRttiInstanceProperty.DoGetValue(???)
:00cf54ae TRttiProperty.GetValue + $26

Since it is pointing to an invalid address the Access Violation is when the code tries to execute Model.CaretPosition.

Using Chrome there is still no warning. I got the warning using FireFox.

Use Google Chrome, no error messages.

If you are using a standard windows user then you must start the IDE elevated in order to have a chance to verify which patches are installed.

You see he images because the IDE will copy paste the reference to the imagelist on the DM. The compiler will find the DM containing the pictures and will show them. You can save the form, close all the projects and open the form the IDE will remove the reference to the datamodule and you will not see the pictures anymore.

This also fails in XE5 and 11.2.

FireDAC is using the meta information from the connection library to determine the data types. You can try to use cast to change the data type for the field in your test application.

The version also matters since it was changed for version 12.
