Hi,
if your interfaces are located in a type library, you need to load the
type lib first:
from comtypes.client import GetModule
GetModule(('{TYPELIB_GUID}', VERSION_MAJOR, VERSION_MINOR))
or your can use the dll directly:
GetModule('typelib.dll')
When correctly loaded, you should be able to import the generated python
file
import comtypes.gen.YOUR_TYPELIB_ALIAS
then you can do the type cast to your interface
instance =
smi.QueryInterface(comtypes.gen.YOUR_TYPELIB_ALIAS.IYourInterface)

Betreff: [comtypes-users] How to create an instance of Interface of a
COM.
Could anyone help me ?
I'm trying to use Animatics' SMIEngine from comtypes.
It's expalined here.
http://www.animatics.com/products/software/animatics/code-dev-software/smiengine.html
I installed SMIEngine.
I could create an instance of 'SMIEngine.SMIHost'.
This is what I did.
>> import comtypes.client as cc
>> smi = cc.CreateObject('SMIEngine.SMIHost')
Next, I must create an instance of ISMIComm.
>> smiCom = smi.QuerryInterface( ?? )
At this point, I lost my way.
I looked it with OLE/COM Object Viewer.
