I have tons of them but this is what I could find quickly as a sample:

TESTDATALOC = _samples+"data\testdata.DBC"

oForm = createobject('myForm')
oForm.Show
Read events

Define CLASS myform AS form
  Top = 0
  Left = 0
  Height = 450
  Width = 750
  DoCreate = .T.
  Caption = "Form1"
  Name = "Form1"

  Add OBJECT command1 as commandbutton with ;
    Autosize = .t., ;
    Top = 0, ;
    Left = 0, ;
    Name = "Set1", ;
    Caption = 'Sample 1'

  Add OBJECT command2 as commandbutton with ;
    Autosize = .t., ;
    Top = 0, ;
    Left = 0, ;
    Name = "Set2", ;
    Caption = 'Sample 2'

  Add OBJECT command3 as commandbutton with ;
    Autosize = .t., ;
    Top = 0, ;
    Left = 0, ;
    Name = "Set3", ;
    Caption = 'Sample 3'

  Add OBJECT command4 as commandbutton with ;
    Autosize = .t., ;
    Top = 0, ;
    Left = 0, ;
    Name = "Set4", ;
    Caption = 'Sample 4'

  Add OBJECT hflex AS olecontrol WITH ;
    Top = 0, ;
    Left = 0, ;
    Height = 420, ;
    Width = 750, ;
    Name = "Hflex", ;
