  iTop:=GetIniInt('chkb', 'Top', '50', ExpandConstant('{src}') + '\YourFile.ini');  
  iWidth:=GetIniInt('chkb', 'Width', '150', ExpandConstant('{src}') + '\YourFile.ini');
  iHeight:=GetIniInt('chkb', 'Height', '20', ExpandConstant('{src}') + '\YourFile.ini'); 
  bChecked=GetIniBool('chkb', 'Checked', 'true', ExpandConstant('{src}') + '\YourFile.ini');

  CheckBox1.Caption:=sCaption;
  CheckBox1.SetBounds(iLeft, iTop, iWidth, iHeight);
  CheckBox1.Checked:=bChecked;
