I know what strings are. A couple of people said TStrings was an Array Of Strings, but then Boreas and NewToAutoing said that would be TStringArray.

Anyone mind explaining TStrings to me? Perhaps on MSN?

this is What a TString Array would be…

program New;
var
   S : TStringArray;
   i : integer;

begin
S := ['Hey', 'Hah', 'Blah'];
 for i := 0 to Length(s)-1 do
 Writeln(S[i]);
end.

and TString is used for like objects..
like ListBox.TString(Items).Add('hey');

program New;



var
  MainForm : TForm;
  ListBox : TListBox;


procedure InitForm;
begin
  MainForm := CreateForm;
  MainForm.SetBounds(0, 0, 300, 200);
  MainForm.POSITION:= poDesktopCenter;
  MainForm.BORDERICONS:= [biMinimize, biSystemMenu];
  MainForm.BORDERSTYLE:= bsSingle;
  MainForm.Color := 0;
  MainForm.Caption := '';

  ListBox := TListBox.Create(MainForm);
  ListBox.Parent := Mainform;
  ListBox.SetBounds(10, 10, 100, 100);
  ListBox.Items.Add('Add'); // Items = TString
  ListBox.Items.Append('Muhahha');

  MainForm.ShowModal;
end;

procedure SafeInitForm;
var
  v: TVariantArray;
begin
  setarraylength(V, 0);
  ThreadSafeCall('InitForm', v);
end;


begin
try
  SafeInitForm;

  finally
     FreeForm(MainForm)

  except
 Writeln('ERROR: With Loading');
 end;

end.

If you know what types are, its a type string.

Time for me to read a tutorial then…

Well. to sum it up, a type is like an array.

Like the type

 TUser;

is what holds the variables found in the

Var
 Players: Array [0..?] of TUser

Player array.

It's not a 'type string'. It's an object that is used to store and manipulate an array of strings. It can also hold other objects (I think).

For example:

var
  MyStringList : TStringList;

begin
 MyStringList:= TStringList.Create; { Our array is now [] }
 MyStringList.Append('1');          { Now ['1'] }
 MyStringList.Append('2');          { Now ['1', '2'] }
 MyStringList.Insert('0', 1);       { Now ['0', '1', '3'] }
 MyStringList.Delete(3);            { Now ['0', '1'] }

 Writeln(MyStringList[0]);          { Will write "0" }
end.

Sorry if thats using wrong params or w/e. I don't have SCAR on me.

Ohh! I thought it was a type because of the T….

Ooo, that helps a bit.

its a Class Type :)
(im pretty sure)
