...ANSWER
Answered 2022-Apr-17 at 23:55I assume you are trying to access an optional property.
Try calling it like so SMU.Measurement.Trace.GetAverageReading()
.
Alternatively you can try str(SMU.Measurement.Trace.GetAverageReading)
to check whether it has a valid string representation attached.

I'm trying to control a device (Gamry Interface 5000 Potentiostat) via its COM interface using win32com.
...ANSWER
Answered 2022-Feb-07 at 14:42"Class not registered" means it cannot find the class factory for the class. That's an error independent of Python and has nothing to do with it...other than the bitness of Python (whether it is 32 or 64-bit, and whether the COM server is 32 or 64-bit). It also matters whether the server is In Process (a DLL) or Out of Process (EXE). For EXE, it really doesn't matter, but for an In-Process server, the bitness of the calling program and the COM server have to match. In order to see if you have a bitness problem, do this...

QUESTION
I am trying to use pyttsx3 for a simple voice message but if i put this in a try except block though the voice message is generated there are many unwanted debug logging prints generated ,Is there any way to disable logging for this particular module pyttsx3
I tried the logging.getLogger("pyttsx3").setLevel(logging.INFO)
but it didn't help

Answered 2021-Oct-21 at 11:00Since the logging comes from comtypes

, maybe try this:
logging.getLogger("comtypes").setLevel(logging.INFO)
QUESTION
I'm attempting to use low level Windows API's (specifically FindFirstFileW
/ fileapi.h
) in a UWP app for the first time.
I have proof of concept code running successfully in a .Net console app, and now want to try it in a UWP app (personal hobby project). The import statement uses SetLastError = true:
...ANSWER
Answered 2021-Oct-18 at 09:04I tried the code, the code returns the same result as you mentioned. The document of FindFirstFileW
mentions this API could be used in UWP apps but it will still be limited by the UWP apps as the UWP are running in the sandbox.
If you are trying to find a file and its handle, there is another way that you could do that. You could get a brokered file HANDLE from a StorageFile with the IStorageItemHandleAccess interface or from a StorageFolder with the IStorageFolderHandleAccess interface. After you've got the handle, you should be able to use the handle in some win32 APIs to do what you want.
Besides, if you don't mind using the desktop bridge, you could do it in the desktop apps, and then package it together with the UWP app. Use the UWP app to launch the desktop app which calls the win32 APIs to do the work.
QUESTION
Below console application in c#.net shows only folder names in D drive without full path name but I want to have iterate recursively inside the folders , subfolder and files within those subfolders with help of win32 API because of I have to scan folders having thousands of files.

Install comtypes
You can use comtypes like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
