Hi,
there is a bug in comtypes.client.GetBestInterface, as this:
----
## the following code works fine
from comtypes.client import CreateObject
wscriptObj = CreateObject("Wscript.Shell",dynamic=True)
print(wscriptObj.CurrentDirectory)
wscriptObj.run("cmd.exe /c notepad.exe",0)
# But, when drop the "dynamic=True", it will fail
from comtypes.client import CreateObject
wscriptObj = CreateObject("Wscript.Shell")
print(wscriptObj.CurrentDirectory) # Failed, AttributeError: CurrentDirectory
wscriptObj.run("cmd.exe /c notepad.exe",0)
----
Turns out that when progid="Wscript.Shell", in
comtypes.client.GetBestInterface, the pci.GetClassInfo() returned TypeInfo of
the default interface IWshShell3, not of the supposed CoClass WshShell.
GetBestInterface searched IWshShell3, find what it implemented - IWshShell2,
which has no property CurrentDirectory.
So I think here need an if stmt, such as "if (str(ta.guid) == punk.clsid): go
best interface",
or, try IDispatch.GetTypeInfo first.
