[python-win32] ActiveX dll error - Non-modal forms cannot be displayed in this host application

[Mark Hammond]

ActiveX DLLs in a raw python.exe program are tricky.  I'm guessing you need
to use the DLL in a true ActiveX host app - pythonwin is one (see the
pywin\demos\ocx directory) and wxPython can also do it (but I'm not sure
about how it is done there)

 

Cheers,

Hi,

I have an ActiveX dll that I am trying to use in a Python script.

I can dispatch the control, but when I try to runs its 'open' command, I get
the following error:

"Non-modal forms cannot be displayed in this host application from an
ActiveX DLL, ActiveX Control, or Property Page."

My googling seems to indicate that it is either something to do with
threading model differences, or something to do with MsoStdCompMgr.

Does anyone have any suggestions on how to get around this problem??

Cheers,

Rasjid.
