Hello All,
I'm trying to write a Python program that uses a provided ActiveX component.
I have verified the component works ok with Visual Basic.
I have used makepy to build the import module for my ActiveX component.
I can successfully load the component via the ActiveXCtrl class found in
wxPython.
My issue is how to call one of the methods of the ActiveX component. The
method requires a pointer to a variant.
Excerpt from the makepy created module:
def OpenUSB(self, lWarning=defaultNamedNotOptArg):
return self._oleobj_.InvokeTypes(1, LCID, 1, (3, 0), ((16387,
0),),lWarning)
As you can see, the first arg is a VT_BYREF | VT_I4.
How do I call this from Python? How do I get a long int pointer to pass to
this function?
I've played around with comtypes and the VARIANT class, but I can't seem to
find the right combo to get what I need.
