Hello,
>From what I remember having worked on COM/DCOM a few years back, the DLL
needs to have functions defined using a certain return type for all the
functions that are exposed. Then the win32com module can query the DLL to
see what functions are present. Please note that even if they cannot be
queried, they can certainly be used, if you know their signature.
Also look at how to launch an Automation Application from OLE Automation
from Python examples on the web. There are slight differences in how you
launch, and that may be the reason.
PythonWin IDE that comes with the PyWin32 libraries has a OLE/COM Object
viewer that should be able to show you all the functions that are exposed
by a registered DLL.
