    The trouble with memo need to set word wrap to false to track lines.   

     

    Here's a way to simply output to image or Paintbox. Painting StringGrid is above my paygrade.  To call it pass self and a canvas when the view or the data is changed. 

    procedure DrawCanvasPat(Sender: Tobject; Canvas: TCanvas);
begin
  with Canvas do
  begin
    Pen.Width := 3;
    for var C in [0 .. 9] do // := Low to High do FAD here
    begin
      var
      R := 0;
      var
      fields := ['First', '', '', '', 'Mid', '', '', 'H', '', 'Last', 'Ten'];
      // ShowMessage(fields[0]);

      TextOut(C * 45 + 45, R + 23, fields[C]);
      for R in [CSVHeaderTopLine .. 9] do
      begin
        var
        value := (Random(20) - 10);
        if value > 0 then
          Pen.Color := clGreen
        else
          Pen.Color := clRed;
        Rectangle(C * 45 + 60, R * 23 + 30, C * 45 + 64, R * 23 + 33);
        TextOut(C * 45 + 45, R * 23 + 23, value.ToString);

        // ColorDrawItem2(sgUI, sgUI.Canvas,cellValue.tostring,Lrect,TRue);
      end;
    end;
  end;

end;

    I think it might be nice for Linux development if it worked on Raspberry Pis. Can I ask what you want to upgrade to Enterprise for?

    chiefly for the WSL stuff, that would allow learning/running Linux faster than running a Linux box? That was two days ago now I want buy a box to run win pro 11 on it to learn if remote debugging on windows 64 machine using a windows 32 machine would allow faster recompiling.  Still there is regret that I didn't jump on the 20% discount(When I bought the D10.2 with mobile on sale 2000 days ago.  In a month found a newer computer to install it on by then 10.3 was available.)

     

    Raspberry Pi it's just another mouth to feed not in the money involved but in time used in learning curve of what works and how it works.  Learning Python first maybe best for Linux development getting the Pi aspect for free that's my new plan. For windows I think I deserve a p16 or even an HP.

    If I compile my software outside (command-line) the Delphi IDE I have never out of memory problems = And it's stay a lot of memory useable easy to compile more than 20 000 000 lines of code !

    Is the IDE set to save files on a compile? Does the error change to corrupted memory when compiling in 64 bit. I have 1.4 Compressed memory even with 8.2 available so I may reboot the machine to clear the Compressed or swap pages out this week. MS fixed some issues doing away with recently used file time line but putting the swap file back in is maddening :classic_angry:

    I just don't want to begin with a blank project.

    Start with a plan then! Good luck comes from months of careful planning. What about the database, the servers etc. For now, log the bugs to determine if the problem is data entry, codebase, or database design and queries used. Only should then you recompile the hpp files made in Delphi into C++.

    The whole world does it is not much of an argument. 

    Just because a large number of people do something (Windows/MSDOS), does not make it right (MAC OS crew view).  Legacy support is lost in the Mac world a publishing program upgraded to the new flavor of Mac would happily wreck any book at page 65 or so. 

     

    Android Studio needs to run on Linux for good connection to google when it's working your phone over. It does have a Web app option now. 

     

    Visual Studio issues warning do not set root to internet on Linux. plus learning javascript. Boo!

     

    Lazarus I been unable to load on Linux for one, plus it's just a bunch of windows like D1-7.

    I am using 11.3 a big improvement over 10.4 until the blue moon last month. Then the IDE began doing disappearing act like 10.3, after "upgrading" an event in a control in a package. In short recompiling my package of custom controls fixed the issue(s).  Looking at the output messages after a compile I may shut down the OneDrive business if the IDE crashes while hovering over the Search menu again.

    Add TStream argument example

    On 9/15/2023 at 4:32 PM, JohnLM said:

    Im a beginner just learning a few things about Stream, how to Write and Read from it.

    One way to learn Stream is:

     

    1. Add a TMemo to a form in the Designer.
    2. Add lines of text to Memo1 in ObjectInspector usings Lines property editor.
    3. Select the Memo1 in design and cut/paste into notepad.
    4. Tinker with property settings streamed out in notepad.
    5. Stream the adjusted Memo1 back into the designer by pasting notepad text.
    6. Wow. 

     

    Next lesson 

    Place cut out of design window into code by pasting inside a buttonclick.

    modify the pasted so the runtime creates the memo at runtime.🙂

    ...

    Database can use record with fixed string size on one hand and can use JSON for streaming needs. 

     

    TStream  used like TStrings in procedure arguments. MS is passed as a TStream in the TreeView.SavetoStream.

      

    procedure TForm3.Button5Click(Sender: TObject);
var
  MS: TmemoryStream;
begin
  MS := TMemoryStream.Create;
  Try
    TV.SaveToStream(MS);  // TV isa TreeView
    MS.Position := 0;
    Memo1.Lines.LoadFromStream(MS);
  Finally
    MS.Free;
  End;
end;

       Here's a pascal example that simply replaces ProcessMessages with custom "message" calls to allow the sleep delays.

     

       assign this ClickEvent to several buttons onclick Event.  I would look media player source for dealing with updating several buttons state. 

       

    implementation

{$R *.dfm}

const
  Clickable = True; // alias for enabled = True

procedure ButtonEnable(button: TButton; const aCaption: string;
  const isEnabled: Boolean); //inline;
begin
  if button.Enabled <> isEnabled then
    button.Enabled := isEnabled;
  if button.Caption <> aCaption then
    button.Caption := aCaption;
//  button.Enabled := isEnabled; order matters
  //Button.Repaint; //
end;

procedure SnoozedButton(button: TButton; MS: Integer); //inline;
begin
  ButtonEnable(button, 'Snoozed', not Clickable);
  Sleep(MS);
end;

var inUse: Boolean = False;

procedure TForm15.DealButtonClick(Sender: TObject);
begin
  if inUse = not False
    then exit;
  inUse := True;//Sender as TButton;

  SnoozedButton(Sender as TButton, 3000);
  ButtonEnable(Sender as TButton, 'Hit me', not Clickable);

  Sleep(1500);
  (Sender as TButton).Caption := 'Hitted';

  sleep(1500);
  sleepControl(Sender, 2000); // Event driven call

  ButtonEnable(Sender as TButton, 'Deal', Clickable);

  inUse := False;//nil;
end;

procedure TForm15.sleepControl(Sender: TObject; const MS: Integer);
begin
  var
  button := Sender as TButton;
  ButtonEnable(button, 'Sleeping', not Clickable);
  Sleep(MS);
  ButtonEnable(button, 'Stay', not Clickable);
  Sleep(MS);
end;

    Is there a way to disable the highlighting that happens when you simply hover over a button?

    I think that's a feature🙂.  I would like the showhint to work when the button is disabled.

    added FMX side has sizeable viewer

    IDE Startup Layout

    When you open the IDE, RAD Studio displays a startup layout with the Structure, Obect Inspector, Palette, and Projects tool windows collapsed. You can also select the Startup Layout or another pre-defined layout from the dropdown on the top bar.

     

    From the help, the Startup layout hides the "saddle bags." The edges of the embedded form designer use some screen for accessing slide outs but huge improvement over default layout for layout and text editing too!

     

    I added a second icon with this switch dpunaware for different resolutions.

     

    FMX has sizable viewer and shows the background of window behind in form window thumbnail. Either designer doesn't position the design in the thumbnail as designed.

    To view the dproj file more readily, I used treeview's save to file to remove some of the nesting of xml files. 


    Output << Memo << Treeview.save << TreeView from xml file.  

     

    // Only 64 release information checked. DCC still shows// 

    ...

PropertyGroup
    DCC_DcuOutput
        .\$(Platform)\$(Config)
        
        ...    
        
        VerInfo_Locale
        1033
    VerInfo_Keys
        CompanyName=;// DCC still outputs regardless of switch //


...

    AppDPIAwarenessMode

        CompanyName=Pat set memo to word wrap;//

    In our application, we hid the Maximize button in MDI mode because the maximized form would hide the MDI icons (the buttons representing the other, minimized, MDI children) and the user would get confused.

    The minimized MDI children even when showing are confusing except for the well seasoned operator who is using them to find a minimized window in an Excel workspace display.   

     

    Any MDI application should have the task bar menu synched up to the showing windows. Allowing the user to readily select windows in different running apps. 

     

    As for snap hovering--good luck.

    Try explaining it so a 5th grader could understand it.

    Now it's needed to explain so AI can understand it and not make an EOW. (End of World).🙂

     

    By making the program data driven that is each event of the assets is recorded. We can fish out the UI and/or answers later. Complex flat files and top-down approach not needed for every problem.

     

    I added a variant record to post above which isn't used much so removed it. 

    
unit SoccerDB;

interface
uses   // use only whats needed
  Generics.Collections;
  //System.Classes,  Vcl.ExtCtrls, needed for tying into UI
type
  TGameStatus = (gsLeftScheduled, gsRightScheduled, gsPlaying, gameWon, gameLost, gameIssue);

  TTeam = record
    TLA, Country: String;
    Flag: NativeInt;  //pointer to flag
  end;

  PGame = ^TGame;
  TGame = Record
    Team: TTeam;
    Location: string;
    Time,
    Over: TDateTime;     // rather than messing with variant records
    Status: TGameStatus;
    Key: integer;
    Avator: NativeInt; //pointer to Bitmap of location
  End;

  TGames = class(Tlist<PGame>)
    //UIin, UIout: TControls here
    procedure GetTeamsPlayingBetweenTheseTimes(Start, Stop: TDateTime;var theTeams: Tarray<string>);
    procedure SetTeamPlayingatthisTime(Start: TDateTime; ATeam: TTeam);

  end;
implementation

{ TGames }

procedure TGames.GetTeamsPlayingBetweenTheseTimes(Start, Stop: TDateTime;
  var theTeams: Tarray<string>);

begin
  SetLength(TheTeams,2);
  TheTeams[0] := 'USA';
  TheTeams[1] := 'Brazil';

//first get teams playing in time slice
// then sort by location

end;

procedure TGames.SetTeamPlayingatthisTime(Start: TDateTime; ATeam: TTeam);
begin
// make event records here.
end;

end.

    Call it here 

    implementation

{$R *.dfm}
uses SoccerDB;
var
  Soccer2023: TGames;
procedure TForm6.Button1Click(Sender: TObject);
var
  aOutPut: TArray<string>;
  s: string;
begin
  Soccer2023:= TGames.Create;
  Soccer2023.GetTeamsPlayingBetweenTheseTimes(0,0,aoutPut);
  for s in AOutpUt do
  ListBox1.Items.add(s);
  ListBox1.Items.add('Done');
end;
