Delphi - automatically Loads the Last Used of .INI File

Question

I need your help.

Let's say that I have three .INI files: Default.ini, Stack.ini, and Overflow.ini. I just store Default.ini as a variable in the code. This setting of course, it will automatically load the file Default.ini every time the application is run. It's not possible to put all the file names in the code, of course.

So my problem is, when I re-run the application, I want the .ini file that loads automatically is the last recently used of .ini file.

How to do that ?

Thank you for your help and your help would be greatly appreciated!

Below is the most actual important part of my codes [based on MasterMan82's TIniFile code].

......

uses
  Windows, Messages, SysUtils, Variants, Classes, 
  Graphics, Controls, Forms, IniFiles, Dialogs;

......

private
  FCurrentIniFilename: String;

......

var
  Form1: TForm1;

implementation

{$R *.dfm}

procedure TForm1.FormCreate(Sender: TObject);
var
   I, LinesCount: Integer;
   Read         : TIniFile;
begin
   FCurrentIniFilename := ExtractFilePath(Application.EXEName)+ 'Default.ini';
   Read := TINIFile.Create(FCurrentIniFilename);
  Try
   Proxy.Text   := Read.ReadString('SETTING','Proxy','');
   Port.Text    := Read.ReadString('SETTING','Port','');
   Route.Checked:= Read.ReadBool('SETTING','Route',False);
   // TO READ MEMO LINES
   LinesCount := Read.ReadInteger('MEMO', 'Lines Count', 0);
   for I := 0 to LinesCount-1 do
   Memo1.Lines.Insert(I, Read.ReadString('MEMO', 'Item'+IntToStr(I), ''));
  Finally
   Read.Free;
  end;
end;

procedure TForm1.SaveClick(Sender: TObject);
var
   I, LinesCount: Integer;
   ToSave       : TIniFile;
begin
   ToSave := TINIFile.Create(FCurrentIniFilename);
  Try
   ToSave.WriteString('SETTING','Proxy',Proxy.Text);
   ToSave.WriteString('SETTING','Port',Port.Text);
   ToSave.WriteBool('SETTING','Route',Route.Checked);
   // TO SAVE MEMO LINES
   LinesCount := Memo1.Lines.Count;
   ToSave.WriteInteger('MEMO', 'Lines Count', LinesCount);
   for I := 0 to LinesCount-1 do
   ToSave.WriteString('MEMO', 'Item'+IntToStr(I), Memo1.Lines[I]);
  Finally
   ToSave.Free;
 end;
end;

procedure TForm1.OpenClick(Sender: TObject);
var
   I, LinesCount: Integer;
   OpenFile     : TIniFile;
begin    
   if OpenDialog.Execute then begin
    FCurrentIniFilename := OpenDialog.Filename;
    Open := TINIFile.Create(FCurrentIniFileName);
  Try
   Proxy.Text   := OpenFile.ReadString('SETTING','Proxy','');
   Port.Text    := OpenFile.ReadString('SETTING','Port','');
   Route.Checked:= OpenFile.ReadBool('SETTING','Route',False);
   // TO READ MEMO LINES
   LinesCount   := OpenFile.ReadInteger('MEMO', 'Lines Count', 0);
   for I := 0 to LinesCount-1 do
   Memo1.Lines.Insert(I, OpenFile.ReadString('MEMO', 'Item'+IntToStr(I), ''));
  Finally
   OpenFile.Free;
  end;
 end;
end;
