7. „ Hello World“ Microsoft Word from win32com import client word = client.Dispatch( &quot;Word.Application&quot; ) word.Visible = 1 doc = word.Documents.Add() doc.Content.Text = &quot;Hello World&quot;

13. Generierung eines Python-Moduls mit makepy Beispiel-Ausschnitt: PowerPoint  Slides  Add class Slides(DispatchBaseClass): CLSID = IID( '{91493469-5A91-11CF-8700-00AA0060263B}' ) coclass_clsid = None # Result is of type Slide def Add(self, Index=defaultNamedNotOptArg, Layout=defaultNamedNotOptArg): ret = self._oleobj_.InvokeTypes(2004, LCID, 1 , ( 13 , 0 ), (( 3 , 1 ), ( 3 , 1 )),Index , Layout) if ret is not None : # See if this IUnknown is really an IDispatch try : ret = ret.QueryInterface(pythoncom.IID_IDispatch) except pythoncom.error: return ret ret = Dispatch(ret, 'Add' , '{91493445-5A91-11CF-8700-00AA0060263B}' , UnicodeToString=0) return ret

14. Browsen der Schnittstellen mit combrowse

15. Browsen der Schnittstellen mit combrowse PowerPoint

16. Browsen der Schnittstellen mit combrowse Slides Add Slide Parameter

17. Alternativer Browser Type Library Browser tlbrowse.py

18. Beispiel from win32com import client ppt = client.Dispatch( „Powerpoint.Application&quot; ) ppt.Visible = 1 ppt.ActivePresentation.Slides.Add( 1 , 1 ) Index Layout

19. Debugging

26. Events Applikation mit Event-Handler anfordern („Dispatch“) # Dispatch Excel with event handler from win32com.client import DispatchWithEvents excel = DispatchWithEvents( 'Excel.Application' , EventManager) excel.Visible = 1

27. Events Event-Schleife: Auf Events warten # Listen for events import threading, pythoncom stopEvent = threading.Event() while True : pythoncom.PumpWaitingMessages() # Necessary so that python doesn't hog CPU stopEvent.wait( .2 ) if stopEvent.isSet(): stopEvent.clear() break

29. Add-Ins Klasse Addin class Addin(object): _com_interfaces_ = [ '_IDTExtensibility2' ] _public_methods_ = [] _reg_clsctx_ = pythoncom.CLSCTX_INPROC_SERVER _reg_clsid_ = '{2F1E606F-2A7B-46F9-AF6A-267C0036C348}' _reg_progid_ = 'Python.Test.Addin' _reg_policy_spec_ = 'win32com.server.policy.EventHandlerPolicy' def __init__( self ): import win32traceutil; self .application = None def OnConnection( self , application, connectMode, addin, custom): print 'OnConnection' , application, connectMode, addin, custom def OnDisconnection( self , mode, custom): print 'OnDisconnection ' ‚ mode, custom def OnAddInsUpdate( self , custom): print 'OnAddInsUpdate' , custom def OnStartupComplete( self , custom): print 'OnStartupComplete' , custom def OnBeginShutdown( self , custom): print 'OnBeginShutdown' , custom
