Hi,
I am porting parts of a large VB application to python (using 2.5)
where the UI must stay in VB for the moment. I am using the Model View
Presenter where my models and presenters are in python and my view is
in VB.
I am having trouble passing the VB views into my python presenters.
The views are UserControls and implement an interface (IViewDataView
in the example below) which is defined externally in a type library
(ResultsInterfaces in this example). This interface defines the
methods that the presenter can call on the view. So the VB code is:
Dim presenterInPython As Object
Set presenterInPython = CreateObject("VBToPython.MyTest")
presenterInPython.Init vbUserControl.Object
And the python code is:
class MyTest:
_public_methods_ = ['Init']
_reg_progid_ = "VBToPython.MyTest"
_reg_clsid_ = '{AAAAA649-0AF9-40cf-A51B-4BB10DD33074}'
def Init(self, view):
import comtypes
res_id = comtypes.GUID("{417081F1-179E-4856-B996-03043260AB81}")
import comtypes.client as cc
cc.GetModule((res_id, 1, 0))
import comtypes.gen.ResultsInterfaces as ResInt
internalView = view.QueryInterface(ResInt.IViewDataView)
at this point it throws the error (full error at the end):
<type 'exceptions.TypeError'>: Only strings and iids can be converted
to a CLSID.
Could anyone shed some light on what I missing here? I would also
appreciate if someone could point me in the direction of a similar
example or demo.
Cheers
Jose
