I'm working on a practice Application in Firemonkey-RAD Studio XE3-Delphi. When implementing code I get the following errors:

Undeclared Identifier 'TEdit' Undeclared Identifier 'TLabel' 'TLabel' does not contain a member named 'caption' at line 35

I included the code form the project in the following body.

Any help is appreciated. Go easy on me..I'm new to Delphi.

 unit strcode1u1;

    interface

    uses
      Winapi.Windows, Winapi.Messages, System.SysUtils, System.Variants, System.Classes, Vcl.Graphics,
      Vcl.Controls, Vcl.Forms, Vcl.Dialogs;

    type
      Tstrcode1f1 = class(TForm)
        ePlainText: TEdit;
        laEncrypted: TLabel;
        procedure ePlainTextChange(Sender: TObject);
        procedure FormCreate(Sender: TObject);
      private
        { Private declarations }
      public
        { Public declarations }
      end;

    var
      strcode1f1: Tstrcode1f1;

    implementation

    {$R *.dfm}

    procedure Tstrcode1f1.ePlainTextChange(Sender: TObject);
    begin

    end;

    procedure Tstrcode1f1.FormCreate(Sender: TObject);
    begin
    laEncrypted.caption:=
        chr(72)+chr(101)+chr(108)+
        chr(108)+chr(111)+chr(32)+
        chr(87)+chr(111)+chr(114)+
        chr(108)+chr(100);
    end;
    end.

@David Isn't there a term for this behavior? Best I can think of is dine-and-dash... - Jerry Dodge

You say that you are creating a FireMonkey app, but your uses clause contains references to VCL units:

Vcl.Graphics, Vcl.Controls, Vcl.Forms, Vcl.Dialogs

Instead of FireMonkey units:

FMX.Controls, FMX.Forms, FMX.Dialogs

In addtion to @Remy's answer, there's an additional issue. TLabel in FireMonkey doesn't have a caption, as you can see in the Object Inspector.

FMX TLabel no Caption Object Inspector

It (and all of the other FMX controls) use Text instead.

enter image description here

Start by creating a new FireMonkey application (File->New->FireMonkey Desktop Application - Delphi from the IDE's main menu). When the next dialog appears, choose whether you want a FireMonkey HD or 3D application (the documentation can explain the difference between the two).

You can then drop a TLabel and TEdit on your form, name them properly in the Object Inspector, and change your code to this instead:

aEncrypted.Text:= chr(72)+chr(101)+chr(108)+
                  chr(108)+chr(111)+chr(32)+
                  chr(87)+chr(111)+chr(114)+
                  chr(108)+chr(100);
