Preferances

I must provide a means for the User to choose their preferred font, and their preferred font colour. This preferance should be saved to disk in a file called ExtrasPreferances.ini in the root directory of my drive u: drive. When the application loads it should read the users saved preferances and apply them to all of the forms the application subsequently opens. Also since this functionality is likely to be extended in the future you should encapusulate all of this functionality in a class of your own devising which is accesses only from the main form.

   uses
      ..., IniFiles;

   ClassClientOptions = class
   private
     Form1Color : TColor;
   public
     procedure LoadFromFile(FileName : String);
     procedure SaveToFile (FileName : String);
   end;


   // example pof procedure LoadFromFile
   procedure ClassClientOptions.LoadFromFile(FileName : String);
   var
      IniFile : TIniFile;
   begin
      IniFile := TIniFile.Create(FileName);
      with IniFile do
         begin
            Form1Color := IniFile.ReadInteger('Settings', 'FormColor', clBlue);
            // etc ... your code below
         end;
   end;

   use LoadFromFile in OnCreate and SaveFromFile in OnClose of the form

   define variabe with class ClassClientOptions only once and use it as global variable.

Make  Gloabal Variable

like
  Selected_font : String;
  Selected Color : string ;


On form Creation
   with tinifile.create('u:\ExtrasPreferances.in') do
   begin
     Selected_font := readString('Prefered','fontname','');
     Selected Color:= readString('Prefered','fontColor','');
     free;
  end;


And u ll use all these to variables in all ur Forms...
