Re: Call OCX from python?
From WxPython, or from PythonWin.
Other way : call, & drive, Internet-Explorer, who call the ocx.

An ActiveX component (e.g. an OCX) requires to be registered before it can
be used. Usually this is done when the component is installed. If you know
the file name of the OCX start the registry editor running the command:
regedit ([Start] -> Execute -> regedit). Then search for the file name of
the OCX in the registry. One of the hits should lead you to a registry key
where you find on same hierarchy level the [VersionIndepend entProgID] entry.
The name there is what you should use in the win32com.client .Dispatch() as
parameter.
To give an example let's assume you want to use the WSHOM.OCX which is
usually on any Windows system. Looking in the registry for WSHOM.OCX leads
you (probably the second hit) to the key [InProcServer32] in the
{72C24DD5-D70A-438B-8A42-98424B88AFB8} entry. Here you find also the key
[VersionIndepend entProgID] with the standard value of WScript.Shell. You
should exactly know the methods and their parameter to be able to use the
OCX, see the code below :
# Raise a Yes/No/Abort dialog box provided by WSHOM.OCX:
import win32com.client
axWshShell = win32com.client .Dispatch("WScr ipt.Shell") # WSHOM.OCX
axWshShell_Popu p_Icon_Critical = 16
axWshShell_Popu p_Button_AbortR etryIgnore = 2
axWshShell_Popu p_NoAutoclose = 0
intRetVal = axWshShell.Popu p(
### Raise a message box:
" The Popup() Text" + "\n" +
"",
axWshShell_Popu p_NoAutoclose,
" The Popup() Title:",
axWshShell_Popu p_Icon_Critical + axWshShell_Popu p_Button_AbortR etryIgnore
)
axWshShell_Popu p_Clicked_Abort = 3 # [Abort] button
axWshShell_Popu p_Clicked_Retry = 4 # [Retry] button
axWshShell_Popu p_Clicked_Ignor e = 5 # [Ignore] button
if(intRetVal == axWshShell_Popu p_Clicked_Abort ):
print 'Abort clicked, return value = %i'%(intRetVal, )
if(intRetVal == axWshShell_Popu p_Clicked_Retry ):
print 'Retry clicked, return value = %i'%(intRetVal, )
if(intRetVal == axWshShell_Popu p_Clicked_Ignor e):
print 'Ignore clicked, return value = %i'%(intRetVal, )
To make this example complete, here an excerpt from the registry :
[HKEY_CLASSES_RO OT\CLSID\{72C24 DD5-D70A-438B-8A42-98424B88AFB8}\I nProcServer
32]
@="E:\\WINNT\\s ystem32\\wshom. ocx"
"ThreadingModel "="Apartmen t"
[HKEY_CLASSES_RO OT\CLSID\{72C24 DD5-D70A-438B-8A42-98424B88AFB8}\V ersionIndep
endentProgID]
@="WScript.Shel l"

P.S. if you face problems with return values or parameter values, one of
reasons can be, that OCXses work always with Unicode strings and you haven't
taken it into consideration.
