Hi,

I am trying learn Lazarus (also pascal)
How I can open Form2 ?

I tried 
Form2.Show;
 and
Form2.ShowModal

Didn't work

How it happens ?

Is it any Lazarus training book for beginner or can I find somewhere
else information regarding lazarus.

BR,
ilpo

I found solution
Next you can read what i did (for other beginers)

I added following things to Unit1:
-  Unit2 -> Uses section
-  Form2: TForm2; -> Var section


in Form1 I have TButton. When you click it following program start in
unit1 and Form2 will open (you have to  make program to unit1)

procedure TForm1.TButtonClick(Sender: TObject);
begin
   Form2 := TForm2.Create(Application);
   Form2.Show;
end;


I hope that this help other beginers (sorry my english)

Of course one can type this in the Project Source (yourproject.lpr)
-----------------------------------------
program Project1;

{$mode objfpc}{$H+}

uses
  Interfaces, // this includes the LCL widgetset
  Forms
  { add your units here }, Unit1, Unit2;

begin
  Application.Initialize;
  Application.CreateForm(TForm1, Form1);
  Application.CreateForm(TForm2, Form2);
  form2.visible:=true; // <------------ add this.
  Application.Run;

end.

Marmin, unless you're more experienced, editing your lpr-file is not
advisable. The way to call form2 from form1 is approximatly as ilpo
said:
Code: [Select]
implementation

uses
  Unit2;

// More code
procedure TForm1.Button1Click(Sender: TObject);
begin
  Form2 := TForm2.Create(nil); // nil can be self aswell
  try
    Form2.ShowModal
  finally
    Form2.Free;
  end;
end;

For basic turorials on Lazarus you can have a look at the WiKi or look
at delphi.about.com
