Building basic dialog in Windows?

Here's a class for Windows progress bar:

#
# Progress bar control example
#
# PyCProgressCtrl encapsulates the MFC CProgressCtrl class.  To use it,
# you:
#
# - Create the control with win32ui.CreateProgressCtrl()
# - Create the control window with PyCProgressCtrl.CreateWindow()
# - Initialize the range if you want it to be other than (0, 100) using
#   PyCProgressCtrl.SetRange()
# - Either:
#   - Set the step size with PyCProgressCtrl.SetStep(), and
#   - Increment using PyCProgressCtrl.StepIt()
#   or:
#   - Set the amount completed using PyCProgressCtrl.SetPos()
#

from pywin.mfc import dialog
import win32ui
import win32con
import time

def MakeDlgTemplate():
 style = (win32con.DS_MODALFRAME |
  win32con.WS_POPUP |
  win32con.WS_VISIBLE |
  win32con.WS_CAPTION |
  win32con.WS_SYSMENU |
  win32con.DS_SETFONT)
 cs = (win32con.WS_CHILD |
  win32con.WS_VISIBLE)

 w = 215
 h = 36

 dlg = [["Progress bar",
  (0, 0, w, h),
  style,
  None,
  (8, "MS Sans Serif")],
  ]
 return dlg

class TestDialog(dialog.Dialog):
 def OnInitDialog(self):
  rc = dialog.Dialog.OnInitDialog(self)
  self.pbar = win32ui.CreateProgressCtrl()
  self.pbar.CreateWindow (win32con.WS_CHILD |
      win32con.WS_VISIBLE,
      (10, 10, 310, 24),
      self, 1001)
  return rc

def demo():
 d = TestDialog (MakeDlgTemplate())
 d.CreateWindow ()
 for i in xrange(100):
  d.pbar.SetPos(i)
  time.sleep(0.1)

 d.OnCancel()

if __name__=='__main__':
 demo()


Here's some code for a file dialog box that I stripped from
an application that asks user to select an export file
from TimePilot payroll application (the files are always
called TimePilot.mdb):

import win32ui
import win32con

#---------------------------------------------------------------------------
----
# Display a file dialog box that allows the user to browse to the
TimePilot.mdb
# file that they wish to export.
#---------------------------------------------------------------------------
----
timepilotdatapath="C:\TimePilot"
f=win32ui.CreateFileDialog(1, None, "TimePilot.mdb", 0,
                           'TimePilot databases|TimePilot.mdb||')
f.SetOFNInitialDir(timepilotdatapath)
f.SetOFNTitle("Timepilot Extracted Data")
result=f.DoModal()
if result == win32con.IDCANCEL:
    emsg="Cancel button pressed during TimePilot.mdb file selection,
aborting"
    sys.exit(emsg)

mdb_path=f.GetPathName()
