I thought Remy mentioned using Add with a memo control. Here is a Sample using a nested procedure and a procedure with arguments that pass in controls that update the UI as needed.  This sample uses both Format and ToString to help show the logic in the  Controls as the program runs. 

implementation

{$R *.dfm}

const
  BooleanOperators: TArray<string> = ['And', 'or', 'xor','NotAnd','NotOr'];

var
  A, B, RC: Boolean;

procedure TForm13.Button1Click(Sender: TObject);
begin
  A := True;
  B := True;
  // filter the controls props here use nil or '' if control or string not made yet
  demo357Repair(Memo1.Lines, Listbox1.Items, nil, A, B);
end;

{ TForm13 }
/// <summary>
///  The TStrings of TMEMO are passed and requires a Memo1 and a Listbox1 to work
///
/// </summary>
procedure TForm13.Demo357Repair(const memoStrs, lbAItems, lbBItems : TStrings;var argA,argB: Boolean);
      // this flyover updates the value of RC each pass
      // how would you update A each time
      function flyoverCase(const Idx: NativeInt): Boolean;
      begin
        case Idx of
          0: Result := argA and argB;
          1: Result := argA or argB;
          2: Result := argA xor argB;
          3: Result := not argA or argB;     // adjust these to suit your schema
          4: Result := argA and not argB;
        else
          begin
            Result := False;
            memoStrs.Add('flyover needs attention');//surface errors
          end;
        end;
        // A := Result;
        // UX = User outputs
        memoStrs.Add( Format('%2s = %2s %s %2s', [RC.toString, argA.ToString(True), BooleanOperators[Idx], ArgB.ToString(False)]) );
        lbAItems.Add(RC.ToString);
        //how would you connect lbBItems

      end;
begin
  for var I := Low(BooleanOperators) to High(booleanOperators) do
    RC := flyoverCase(I);
end;

My futile fight with toolbars in Delphi started with Delphi X?? and continues to this day. But I found a solution: I turned off all toolbars and left only the palette on top 🙂(To be honest, I did not try to enable any of toolbars in Delphi 12.2, so I am not sure that problems persist.)

I like the extra one or two code lines showing gained by not showing them.  If only the debug pause button had a key. 

procedure TForm1.Button1Click(Sender: TObject);
begin
1
2 -- debugging started via F8. 
3
4
5   
6
7 -- stop debugging after this. so if i press F8, debugging will not continue to step past it 7. // move to end
8
9
end;// <== put break point here to stop loading the next block or unit use F9 to resume or f7 to enter

By putting a trap at the end lets you use F9 to advance to trap to either move to next routine or F9 to run.  As the program is debugged these traps are last to remove.  

Does baseform have the onMyEvent assigned to empty event simply a frameclick(Sender:TObject)begin..end?  

doing that allows the inherited form a stub to hook up its event.

BTW, also since I took over MMX there has been no one sending any usage report (perhaps it just works on my tests but not in the wild), so I don't have any numbers of what people use most or least. While I would not drop any features based on such numbers, they would give me some hints of MMX features that may just be unknown and lack some promotion.

The feature I like best is the time loading metric when starting the IDE... Mostly the reading is 1728 if the reading is above 22xx I will restart the IDE several times to freshen the OS file MRUs/caches.  When the reading was 65xxx the machine was having a quota issue*.  It would interesting to compare MMX load time on different machines.  The tip of the day, refactor with and link-analyzer are used or useful.  Thanks for providing it.

*Edge died off then and only D12 ran albeit no Co-Pilot .  The next months windows update fixed the issue.    

I had had some luck following these rules. 

• Place only mature controls in the palette. 
• If a control coding is changed just select Install that seems to tell the IDE to do the right thing.  Needs to be 32 bit to see install.
• Any existing control needs removed from the designer view with ctrl X and the control gets the update as it pasted back in. This saves restarting the IDE.
• Check the path of control ensure that it's codebase made the trip to 290  and not using a control that using a 11 or 280 codebase.  
• Have a  sub project that allows the custom controls and forms to be compiled as standalone allowing modular construction getting custom controls working. then the main project uses the forms that have the controls placed on them.    

My machine shows the same but shows 131.xxx when compiled as 64 I set the kernel32 to Kernelbase. My swapfile is hard set at 2917 or so.

1. Read the "hints" on the error your compiling for "32" 64 with version 35.0 compiler switched to using a D11 path. I would say its a proj copied from d11 codebase to to a d12 codebase that kept the d11 proj guid.

Precise enabled a global contact lens provider to defer purchase of millions of dollars on additional hardware, reduce user complaints, and cut programmers’ problem resolution time from 10 days to 3 days.
 

They could get a free trial of a Tool to resolve issue here https://www.idera.com/ppc/precise/performance-intelligence-from-click-to-storage/    That product may provide a remedy. 

1.  form := GetParentForm(AControl);

2. example  speedbutton click overridden to allow click to jump to control on another form. 

  TpfJumper = class(TSpeedButton)
  private
    FgotoName: string;
    FgotoControl: TControl;
    procedure SetgotoControl(const Value: TControl);
    procedure SetgotoName(const Value: string);
//    procedure onclick;

  protected
    procedure Paint; override;
  public
    property gotoControl: TControl read FgotoControl write SetgotoControl;
    property gotoName: string read FgotoName write SetgotoName;
  published
    { Published declarations }
    procedure Click; override;

  end;

3. The events for the Control. 

Procedure TpfJumper.Paint;
begin
  with Canvas do
  begin
    brush.Color := clMoneyGreen;
    Point(85,21),Point(17,0)]);
    polygon([Point(68,0),Point(68,7),Point(85,7),Point(85,34),Point(68,34),Point(68,41),                          Point(0,21),Point(68,0)]);
  end;
end;

procedure TpfJumper.click;
begin
  inherited;
  gotoControl.Show;
end;

4.  In the designer you can assign several controls to one event.  In the handler cast the sender as needed.       

How about qualified with.

procedure TMyForm.UpdateInventoryItem(const NewQty: Integer);

  procedure &With(A: TDataModule; B: TTable; const NewQty: Integer);
  begin
    B.Edit;
    B.FieldByName('Qty').AsInteger := NewQty;
    B.Post;

  end;

begin
  &With(dmStoreInventoryData,
    dmStoreInventoryData.tblUpdateItemForStore, NewQty);
end;

How about a second machine for the user.   They can view old work flows to gain insight on the work flows they are working on presently.  This second machine is simply left on so it doesn't need to download the "knowledge base" each time a user wants to know how a work flow was implemented last time. Since a second machine and screen is used you could charge additional license fees.  If the user can get more done each day by running a second application on second machine it should pay off since first machine used for work orders and IT work done concurrently on second machine albeit losing their "knowledge base" view when backing up.  In short, Historian functions adds a lot of overhead in bandwidth and screens!

Also calling Abort into the constructor will destroy the form.

How about         

procedure TChangeForm.dostuff(inDBName, inDBTable, inTable: Variant)

if not assigned(Changeform)  then Changeform := Tchangeform.create(Application);

hookup up the incoming

If 12 acts up I been restarting it several times just to freshen the file caches MRU.   A pinched network cable caused some issues last spring. 

Mm,  What happens using F7 vs F9 key to run the program.     

Hey,  Where's the blue dots  I would check in project manager  that debug is bolded.

Mouse.CursorPos is expressed in screen coordinates, not client coordinates.  You would need to use PaintBox1.ScreenToClient() in this case:

Oops! Should stuck with mouseover events to allow a "Proper" FocusRect to be drawn when over the area or subtracted the Control's ClientOrigin.Y

procedure TForm23.PaintBox1Click(Sender: TObject);
begin
   if Mouse.CursorPos.Y > 100 then exit;
end;

procedure TForm23.PaintBox1MouseUp(Sender: TObject; Button: TMouseButton;
    Shift: TShiftState; X, Y: Integer);
begin
  if Y < 100 then dostuff
end;

Try an OnMouseOver event and perhaps a PtinRect for the cursor's xy position.

I usually use notepad++ when touching the dfms as text. But for viewing you could do the following.

• Select desired nest in design and copy. 
• Open new Vcl form.
• Paste selected controls on edit form
• Adjust controls 
• Paste adjusted controls back to source design window.
• Make new unit an inline or embedded frame to reduce nesting in source form?

Lazarus leaves the text view up once viewed as text but not really useful most of the time.

I need help because they tell us that it is necessary to use a tabcontrol for the tabs.

Tell they tabs Ok in IDE or XL spreadsheet viewed across a sizable monitor not for a phone! Set the tabvisible to False and use a Button captioned with '...' to show list that 'spins on touch'.

show they the MultiviewDemo or TCardPanel for alternatives.

Could it be that a 11.0 project was copied and renamed to a 11.2 project without changing the guid of new 11.2 project so Delphi 11.2 still looks at 11.0 project source history?

Assign the same mouse enter and mouse leave event for each of the controls in question.

Looking at the .dfm as text we can see that the same mouse enter / leave event was manually set.

  object Rectangle1: TRectangle
    Position.X = 80.000000000000000000
    Position.Y = 232.000000000000000000
    Size.Width = 489.000000000000000000
    Size.Height = 177.000000000000000000
    Size.PlatformDefault = False
    OnMouseEnter = Panel1MouseEnter
    OnMouseLeave = Panel1MouseLeave
    object Button1: TButton
      Position.X = 128.000000000000000000
      Position.Y = 74.000000000000000000
      TabOrder = 2
      Text = 'Button1'
      TextSettings.Trimming = None
      OnMouseEnter = Panel1MouseEnter
      OnMouseLeave = Panel1MouseLeave
    end
    object Button2: TButton
      Position.X = 352.000000000000000000
      Position.Y = 70.000000000000000000
      Size.Width = 89.000000000000000000
      Size.Height = 27.000000000000000000
      Size.PlatformDefault = False
      TabOrder = 1
      Text = 'Button2'
      TextSettings.Trimming = None
      OnMouseEnter = Panel1MouseEnter
      OnMouseLeave = Panel1MouseLeave
    end
  end

The following is assigned event.

procedure TForm8.Panel1MouseEnter(Sender: TObject);
begin
  Caption := 'Hovering over ' + TControl(Sender).name;
  Rectangle1.Fill.Color := TAlphaColorRec.Red;
end;

procedure TForm8.Panel1MouseLeave(Sender: TObject);
begin
  Caption := 'Not hovering over ' + Rectangle1.Name;
  Rectangle1.Fill.Color := TAlphaColorRec.Green;
end;
