>From what you write I conclude, that it is maybe a very good idea to stay
with Visual Basic and use it to create the appropriate ActiveX components
you need in Python and then register them to use it from Python. This way
you can 'marry' what you have already created in Visual Basic easily with

related tasks, because each platform has own specifics which usually are
very interesting for use in own programming and that kills as a consequence
the cross-platform usage.
# For example a Yes/No/Abort dialog box can be achieved using the WSHOM.OCX
available in Windows as follows:
axWshShell = win32com.client.Dispatch("WScript.Shell") # WSHOM.OCX
axWshShell_Popup_Icon_Critical = 16
axWshShell_Popup_Button_AbortRetryIgnore = 2
axWshShell_Popup_NoAutoclose = 0
intRetVal = axWshShell.Popup(
### Raise a message box:
" The Popup() Text" + "\n" +
" The Popup() Title:",
axWshShell_Popup_Icon_Critical + axWshShell_Popup_Button_AbortRetryIgnore
axWshShell_Popup_Clicked_Abort = 3 # [Abort] button
axWshShell_Popup_Clicked_Retry = 4 # [Retry] button
axWshShell_Popup_Clicked_Ignore = 5 # [Ignore] button
if(intRetVal == axWshShell_Popup_Clicked_Abort):
print 'Abort clicked, return value = %i'%(intRetVal,)
if(intRetVal == axWshShell_Popup_Clicked_Retry):
print 'Retry clicked, return value = %i'%(intRetVal,)
if(intRetVal == axWshShell_Popup_Clicked_Ignore):
print 'Ignore clicked, return value = %i'%(intRetVal,)
Hope this is what are you looking for, isn't it?
