Use a usb cord to connect to laptop and try some of the demos of fmx 🙂 

Try setting the TabStop property of Radiogroup to True when none of the controls are selected. In the RadioGroups.OnEnter set focus on a control so keys can change the selection as needed.

//Need RG .TabStop prop set to True to 'focus' the groupbox when its control index
//is -1;
procedure TformInstructorStation.RadioGroup2Enter(Sender: TObject);
begin
  with Sender as TRadioGroup do
    if ItemIndex = -1 then
      TRadioButton(Controls[0]).SetFocus;

 //(Sender as TRadioGroup).OnEnter := nil;
end;

How about a collection of check boxes  TCheckListBox 

The sample simply clears the checkboxes that were in the IDE and adds the ones that are in Array<string>

To extend you would change the Panel and Tstrings that the UI uses update the backend. Here the back end simply updates the UI when programs are used.

It uses a Ddd pattern Data driven pattern.  " Update the data early and often"   

class function TptrApps.HookInUI(inSG: TStringGrid; inLog: TStrings; inChBxs: TcheckListBox;
     inBanner: TPanel): TptrApps;
begin
  Result := nil;
  focusedApp := @cacheApp;
  var R := TptrApps.Create;

  R.ChBxs := inChBxs;
  R.ChBxs.OnClick := R.changeExesList;
  R.ChBxs.Items.Clear;
  for var I := Low(goodApps) to High(goodApps) do
    begin
      R.ChBxs.Items.add(goodApps[I]);
      R.ChBxs.Checked[I] := True;
      ...

const
  selfClass = 'FrmPat';

  GoodApps: Tarray<string> = [cEveryThing,'Shell_TrayWnd','Notepad', 'TAppBuilder', 'Window',
   'Chrome_WidgetWin_1', 'Notepad++', selfClass, 'TfmPeInformation' ];
      

Or like the minesweeper game. Test for "open water" or "good ice".  A test returns the position in range with start and stop of range when found and could return the size of the "open water" when not found.

The employee needs to share calendar so you can look at it.  

Outlook's contact info is a vcard file and calendar event is vcalendar *.vcs or *.ics file. The employee calendar shows the events provided by the calendars the employee has access to. 

Example of email attachment
https://answers.microsoft.com/en-us/outlook_com/forum/all/how-to-insert-attachment-to-recurring-meeting 

You would simply add an event attachment to the email of employee.

But better to educate the office staff how to use Outlook calendar by having the secretary set the events on the employee calendars as needed. 

Employee leave requests are sent to office manager. If approved the secretary amends the department's calendar which updates the employee calendar.

The employee looks at the calendar events provided by the secretary. The secretary knows when the employee knows of a calendar event by the employee opening an email with a calendar event attachment and confirming the event.

Here's my 7 cents worth.  'Explicitly' use a's Value to remove need for braces.

var
  a: TplFilterValue<Boolean>;
  B: Boolean;
  procedure  //Boolean User output
    Bout (argS: string; aB: Boolean);
      begin
        writeln(argS + ' = ', aB);
      end;
  function
    NotFixup(aB: TplFilterValue<Boolean>): Boolean;
      begin
        Result := not aB.Value;
      end;

begin
  try
    a.Value := True;
    //if not a then
      Bout('not a', not a);
      Bout('a or True', a or True);
      Bout('a and True', a and True);

    Writeln('  NotFixup');
    //if not a or True then  // <<--- Error [dcc32 Error] E2015 Operator not applicable to this operand type
      Bout('Notfixup(a) or True', NotFixup(a) or True);
      Bout('NotFixup(a or True)', NotFixup(a or True));

    Writeln('  Precedence manual sort fix');
     // Bout('True or not (a)', True or not (a));
      Bout('True or not a', True or not a);

    Writeln('  not precedence working for boolean here');
      B := a;
      Bout('not B or True', not B or True);
      a := not B or True;
    Writeln('  Or use a''''s Value explicitly :)');

      Bout('not a.value or True', not a.value or True);

    readln;
  except
    on E: Exception do
      Writeln(E.ClassName, ': ', E.Message);
  end;
end.

Currently Delphi doesn't really qualify as a good teaching language any more - which I think is really sad.

Without some more modern language facilities, it would be unfair to modern (say university level) students, and I'd like to see that change. 

// Define a record type as a data class
data class cpRecord(
    var UI: TStringGrid, // Assuming this is a custom type
    var compute: TProc, // Assuming this is a functional type
    var Value: PDouble // Assuming this is a pointer type
)

// Define a custom generic list as a subclass of MutableList
class TcustomList : MutableList<cpRecord> {
    // Delegate the implementation to an ArrayList
    private val list = ArrayList<cpRecord>()

    // Implement the abstract methods of MutableList
    override val size: Int
        get() = list.size
...

I think "port"able coding should be what is taught. Starting with Excel.

Above code from a "Bing" prompt porting a Delphi TList<PRecord> to Kotlin.  The "Precords" allow more shallow code on D jobs and should allow a port on the Android side.

In the past one could simply use JS.evaluate(some script).

Here is a sample using a ColorDialog and ListBox.  Note In the IDE you can interact with the colordialog on the form to preload custom colors. The ColorDialog can be to show full with in object inspector.

procedure TForm1.Button1Click(Sender: TObject);
begin
 If ColorDialog1.Execute Then
 Listbox1.Items := ColorDialog1.CustomColors;
end;

procedure TForm1.ListBox1Click(Sender: TObject);
begin
  if Sender is TListBox then
    begin
      var lb := TListBox(Sender);
      var I  := lb.ItemIndex;

      Color := StrtoInt('$'
                         + lb
                            .Items
                            .ValueFromIndex[I]
                       );
    end;
end;

Something that is often overlooked is to limit the redraw frequency. If you redraw the display on every update and there are many updates per second, you may save a lot of time on triggering the invalidate at a capped rate, i.e. not do a full redraw every time, but update once every fixed time interval.  Unless you are doing video processing - a redraw at maximum twice per second should be more than sufficient?

But overclocking is fun!

Using paint; override; with say TShape a tGraphicalControl allows using inherited to draw existing shape and add text as needed. Not using inherited means drawing your own polygon. The sample simply draws over the TShape control Ok But the focus rect yielded some relics.

In the past it was necessary to exit a timer event when busy or in debug mode. Even with example switches the following stacks up clicks events. I put a call to Button8click in the formPaint and it ran but slowly. 

Otherwise just invalidate the controls as needed. 

var Button8clickIsBusy: Integer = 0;
var OneShot: Boolean = False;

procedure TForm1.Button8Click(Sender: TObject);
const
  Red = clRed;
  Green = clGreen;
  Colors: Array of Tcolor = [clGreen,clRed,clBlue,clYellow];

var
  sw: TStopwatch;
  sX: string;

         function RandomFontColor: Tcolor;
         begin
           var Clr := High(Colors);
           var R := Random(Clr);
           Result := Colors[R];
         end;

begin
  sw.Reset;
  sw.Start;
  If Oneshot then Exit;
  If Button8clickIsBusy > 0
    then begin
           Canvas.TextOut(10,10,'Drawing on Canvas');
           Caption := 'Busy ' + Button8clickIsBusy.ToString;
           Exit;
         end;
  //Canvas.Unlock; // may need
  Inc(Button8clickIsBusy);
  OneShot := True;

  const
    L = Shape1.Left + 5;
  const
    T = Shape1.Top + 5;
  var
    SP: Integer := 0;
  var
    X := -50;
  //Brush.Color := clmoneygreen;
  //Canvas.FillRect(BoundsRect);  //hosed by style and not max windowstate
  Repeat
    sX := X.ToString;
    Canvas.Font.Color := RandomFontColor;
    Canvas.Font.Size := X;
    Canvas.TextOut(20, 20, sX);
    canvas.DrawFocusRect(Rect(22,22,X+X-3,(X-3)*2));

    //on shape
    Canvas.Font.Color := RandomFontColor;
    Canvas.Font.Size := -X;
    Canvas.TextOut(L, T, sX);
    Sleep(20);
    Canvas.Font.Color := clWindowFrame;
    canvas.DrawFocusRect(Rect(22,22,X+X-3,(X-3)*2));

    Inc(X);
  Until x > 50;

  Button8clickIsBusy := 0;
  sw.Stop;

  Canvas.TextOut( 10,100,'Done et='+ sw.ElapsedMilliseconds.ToString);
  Caption := 'Busy ' + Button8clickIsBusy.ToString;
  Oneshot := False;
end;

I think this is a start Henney Lambda? Presentation 2020 NDC has mention of Borland's Pascal and Delphi in it. 

Any computer based training, books, and manuals needs be to discussed over what was learned and review the topics that are unclear should make the onboarding process a learning experience for you as well as the new guy.   

Also studying GExperts source and comments at https://blog.dummzeuch.de/2021/10/24/gexperts-1-3-19-alpha-for-delphi-11/   is good and what the Experts can do is useful!  

Here's sample of updating lineseries and legend in real time   I think the data points should the numbers and be in the legend Second the time axis is usually bottom axis. For old data pass in the datetime of the record and field name of number.    

    s := FormatDateTime('ss', Frac(aSimTime));
    Ptp := Chart1.Series[0];
    if Ptp.Count > 300 then
      Ptp.Delete(0, 100);

    Chart1.Series[0].AddXY(now, FXY.y, s, clRed);
    Chart1.Series[0].Title := 'A ' + FXY.y.ToString;

    if Chart1.SeriesCount > 1 then
    begin
      Ptp := Chart1.Series[1];
      Chart1.Series[1].AddXY(now, FXY.y + 5, '', clBlue);
      Chart1.Series[1].Title := 'A dgr ' + (FXY.y + 5).ToString;

      if Ptp.Count > 150 then

        Ptp.Delete(0, 50);
    end;

  end;

Try this, the tool tip shows the index which can used to access the string. Done in 11.3

var idx : Integer;
const Nus: array of string = ['1', '2', '3'];
begin
  try
    { TODO -oUser -cConsole Main : Insert code here }
    idx := IndexText ('3',Nus);
    WriteLn( idx);
    Writeln(nus[idx]);
    Readln;

It was the one that had the apps running on the server side and sent out the screen shots. Who would run a program that served pix of local machine?

Easy, just add some anime kitties and giant robots to win their hearts! Or... giant kitty robots!

Psychic surgery may be indicated for those with bad luck. 🙂

The only bad luck I know about is the disassembly window not showing on 12. Control-alt-d when stopped at a breakpoint only flickers the other debug floaters. 😞
 

The try...finally...end is typically used to free memory. This sample simply sets the count back to zero and has a counter for number of count resets in the finally. Goto's and try's don't mix.

var
  Count: 0..100 = 0;
  Reentrant: 0..100 = 0;

procedure TForm1.Button2Click(Sender: TObject);
begin
  //Constraint
  If Count > 4 then
    exit;
  (Sender as TButton).Enabled := False;

  Inc(Count);
  Caption := 'Goingto ' + Count.ToString;
  Sleep(100);
  Try
    Caption := Format('Goneto  %d',[Count]);
    If Count < 9 then
    begin
      Sleep(110);
      Button2Click(Sender); //Poor Person's ProcessMessages
    end;

  finally
    Inc(Reentrant);
    Count := 0;
    sleep(12_00);
    Caption := Format('Please !gotos!* use %d jumps',[Reentrant]);
  End;
  //* pram notation Beattie

 //Enables first finally pass :(
 (Sender as TButton).Enabled := True;
end;

Works for me side by side...   Notice how grouping shows a Instance paired with explorer it was paired with Help.  I like the Startup layout and set the message and callstack views that popout in debug view.  My only complaint is D12 icon same as D11 icon?     

Here's some more Information for your consideration.

The problem with the lock-modify-unlock model is that it's a bit restrictive and often becomes a roadblock for users:

• Locking may cause administrative problems. Sometimes Harry will lock a file and then forget about it. Meanwhile, because Sally is still waiting to edit the file, her hands are tied. And then Harry goes on vacation. Now Sally has to get an administrator to release Harry's lock. The situation ends up causing a lot of unnecessary delay and wasted time...

Surely only copies of your documents are being looked at and double checked before changes are recorded into the system.  

Some Entities track employee's computer use and issue "warnings".  What are your peers doing in like setups?

reason for this is cloud server and multiple clients. we give them a specific folder that is theirs but if we allow them to navigate to other clients folders it presents a security problem.

Letting a user even see that another user's folder exists, even if it's not selectable, is just bad UI design and broken security waiting to be exploited.

I would change this to mean each client 'sees' only one 'cloud' or 'channel'. Meaning the Admin for one client's machines would never see another client's channel machines and data. Have each client users use email and password to start windows and access their file share and shared drives as allowed by the logon of that user's account.

PInteger(@IntArr[0]

Shouldn't that be PNativeInt(@ to allow either 32 or 64 compiling. The first 12 compile for me was 11K bigger but additional recompile yielded 45k smaller exe*.  The displays show one NAN and blank "TokenWindow:bds.exe"

*Did remove unused Controls from a package though.

Use ShellAPI and ListBox or ListView perhaps.

Try typing over the path in the FileOpenDialog location bar and see what happens with "cmd" or "explorer" text.😈

In the past using Showing property never worked well for me...  I just the removed the if Showing and just Hide and Show as needed.  

Also I added Step, Run, Stop buttons for timer state.  A Step "freezes" the "program" if timer was enabled. If !timer.Enabled the Step does one OnTimer event. In runtime. 

Or say in Edit mode vs "Freeze". The State machine tells the Windows tiling what to do.  The tiling should have not to deal with the State machine. This tiling either forms or controls get control when active or have focus.  UI is dealt by State machine. The tiler (UI) plays the cards dealt. 

Also simply changing the parent of control can "show" or "hide" in a hurry.

...the internal timestamp of a dcu file is older than the currentl source code of a unit and recompiles it, if necessary. But what exactly does hat have to do with GExperts?

I plan to code an expert to verify the dcus are kept current with current source code because sometimes the current source code needs saved before the dcus are recompiled. I need to simply review and learn more before making additional comment.
