service_creationflags=CREATE_NO_WINDOW

[ThomasTrovon]

Hi Friends.

I use undetected-chromedriver in my project with service_creationflags=CREATE_NO_WINDOW since the @sebdelsol version, and always worked perfectly.

Today I resolved update my packages. I do this from time to time, always looking to be up to date with the newest features. So I get undetected-chromedriver 3.4.6, and Selenium 4.8.2. But when I try to make a simply "get" I receive the following error:

And it occurs only when I use service_creationflags=CREATE_NO_WINDOW, as I always did. When I don't use this, the error does not occurs.

My code is below:

import undetected_chromedriver as uc
from subprocess import CREATE_NO_WINDOW

if __name__ == '__main__':
    url = 'https://www.google.com'

    # Works
    # driver = uc.Chrome()

    # Error
    driver = uc.Chrome(service_creationflags=CREATE_NO_WINDOW)

    driver.get(url)

If someone is going to try to reproduce, try using the same versions that I am using:

• undetected-chromedriver 3.4.6
• selenium 4.8.2

Thanks for yout time, and help...

And how I simply open some site with this, in Python, like, open google... Any code sample friend? It's better, to have some idea..

its in C# - you need to clone or download the repo and the build and run tests using Rider or visual studio

[ThomasTrovon]

So sorry friend. I don't program in C. My whole project is in Python. So this don't will serve to me. But thanks for the try.

[DeLaphante]

okay no problem

Can you show more info on the logs?

Why are you using creationflags. That is the cause.
I spent days and weeks, including everything that's needed for undetectabily, and you just think "ah let's use creationflags"

Friend (@ultrafunkamsterdam). It's not without reason. I use creationflags because I make bots of analysis of games, such as roulette for example (https://stake.com/casino/games/evolution-stake-exclusive-roulette-1). So I have my clients, that I sold my creations.

My bots are made in python, compiled in .exe for windows, for more ease of use, using PyArmor to protect my code. I use Qt Designer to make the interface, so everything that is "processing" I make in threads. So this way I can re-configure the bot in real time without stop him. Because of that, when I compile with PyArmor, I hide python console, to prevent my clients from accidentally closing the window. Same reason with the selenium driver, that starts a prompt window when the driver starts, like I demosntrate in next:

In the case of this photo, it's my bot, with my own analytics, made for my own use. For me, there would be no problem with the black screen. The problem is when I ship to my customers, ordinary people.

I can't imagine how hard it is for you to develop this undetectable driver. I wouldn't even know where to start if I had to do something like that. And I also know that you don't receive anything for all this service since you don't charge anything for the use of your work.

As compensation, if you wish, I can provide you with full access, free of charge, to all my analyzes made for my own use, which I do not sell, rent, and do not loan to anyone. If you wish, I would allow you permanent access, as a reward for your trouble, and for all your work.

If you want this, only thing that you need, is to talk with me in Telegram. My nickname is @ThomasVanini.

[ultrafunkamsterdam]

@ThomasTrovon that's valid enough 🙂. I don't know whether create_nowindow is the solution here. But at least I know what needs to be accomplished, which is that small little black box needs to vanish. Ive seen that before and seems only to appear in headless mode (on windows). Could you try uc.Chome(use_subprocess=False)? That way it will start a detached process instead of subprocess

[AlexPaiva]

Never used headless mode, just using uc.chrome() and pyinstaller with basic settings AND the no-console setting the terminal window for UC still shows up.

[ultrafunkamsterdam]

In can reproduce your error using CREATE_NO_WINDOW.. its a bug but not the solution for your problem. When using 3.4.6 on windows it works correctly (no box) when using
uc.Chrome(headless=True).

I encountered the same issue with you ...
I have to remove service_creationflags=CREATE_NO_WINDOW for a moment..

[Alias419]

Same, worked with previous builds, now i have updated to the new python and all modules. It has reappeared. Found on another site that creationflags is now creation_flags. This resolved my issue.

srv = cus.Service(drv)
if os.name == "nt":
    from subprocess import CREATE_NO_WINDOW
    logger.debug("Preventing a background Browser console")
    srv.creation_flags = CREATE_NO_WINDOW

Could you please upload the full code for driver creation and how to hide the background cmd.
thanks in advance.
