Keystrokes | A jQuery event for capturing key strokes and combo keys | Keyboard library

I'm a cyber security student working on a project which captures keystrokes and saves them to a .txt file (simple keylogger built with python) that'd be stored on a USB flash drive plugged in the target's machine. The key data must then be wirelessly transferred from the USB to another machine. I'm looking for the best way to transfer this data (preferably in real-time). Any tips would be well appreciated. Thanks in advance.

I'm doing an assignment for Assembly programming, and I can't get past this problem. The task is to write a program, in which user types a password, console shows '*' instead of typed letters. After typing said password user presses ENTER which "sets" the password, and requires the user to type the same password again to check if it's the same as set before.

I got this code to work which reads keystrokes, saves typed password and then writes it in the console. But I can't get it to stop on pressed ENTER. (it is set to register only 12 letters now)

I'm trying to write a KMDF driver to simulate keystrokes.

When the driver receives IOCTL_HID_READ_REPORT it redirects the request to a queue:

The goal is to create a program that logs keystrokes and writes it into a text file. Currently, just tapping a key will write that key a hundred times so I'm trying to slow it down a bit.

However, using Sleep() will prevent this whole code from doing anything at all unless I use Sleep(0) (which, as I understand, means "Do not let lower priority threads run").

Code:

I have a WPF desktop application written with NET Core 3.1 and it catches keystrokes with KeyDown command. All characters are caught with the keyboard. When I use a Streamdeck and its System Text feature, which sends keys like a keyboard my WPF app doesn't catch it.

Tested on Notepad and the text sent from the Streamdeck works as it should, e.g. X 1 Enter.

When I debug the only thing that gets sent is Enter key.

I would like to read from stdin on a per character basis without the stdin being flushed. I could not find how to do that after tweaking for hours. Tcl always seems to wait for the channel to be flushed even in fconfigure stdin -blocking 0 -buffering none. Is that true? How would I otherwise approach this?

More explanation:
Imagine a Tcl program that makes its own prompt with some threads running code in the background. I would like this prompt to react to single keystrokes, for example: when you press 'p' (without pressing enter) the prompt reads that character and pauses the threads, when you press 'q' the prompt kills the threads and stops the program. The cleanest and closest solution is shortly demonstrated in the following code snippet.

I have the very simple code below that installs an event handler on confirmPass keystrokes. On registration form submit I want to be able to disable the submit if the passwords do not match. In the 'onClick' event for the registration form if I call confirmPass() it fails to submit, if I comment it out it submits. Why is confirmPass() blocking the programatic form submit?

Here's was appears to be an odd question at least from what I've been able to turn up in Google. I'm not trying to determine IF there's a UAC prompt (I've got a couple of reliably ways to do that, win32gui,GetForegroundWindow() returns a 0, or win32gui.screenshot returns exception OSError at least in my case)

I'm also not looking to BYPASS the UAC, at least from python, I have an update process that's kicking off automatically that I need to get through the UAC. I don't have control of the update process so I don't think it's a good candidate for disabling the UAC with Python. I could just disable the UAC in Win10, but I'd prefer not to if possible. I do have a couple of methods for bypassing the UAC, in one instance where I'm running this in vitualbox I believe I can use VBoxManage guestcontrol to sent keystrokes to the guest system, for a stand alone system I have a microcontroller connected as a USB HID Keyboard, with a basic deadman switch (using the scroll lock to pass data between the python and the microcontroller acting as the HID keyboard) if it doesn't get the signal it sends left arrow enter to bypass the UAC.

What I'm trying to do, and getting stymied with, is verifying that the UAC popup is actually from the update process that I want to accept the UAC prompt for, and not some other random, possibly nefarious application trying to elevate privileges. I can use the tasklist to verify the UAC is up, but I'm not seeing any way to see WHAT caused the UAC prompt. The update process is kicked off from an application that's always running, so I can't check to see if the process itself it running, because it's running under normal operation, I just want to accept the UAC when it's attempting to elevate privileges to update. I've been using a combination of using win32gui.GetWindowText and win32gui.EnumWindows to look for specific window titles, and for differentiating between windows with the same title, taking a screenshot and using OpenCV to match different object that appear in the windows. Both of those methods fail though when UAC is up, which is why I can use them to detect UAC as I mentioned before.

I suppose I could use a USB camera to take a screenshot of the system, but I'd like to be able to run this headless.

Anybody have an idea on a way to accomplish this, as the tree said to the lumberjack, I'm stumped.

Having made a program which streams PNG images to the browser by means of a multipart/x-mixed-replace Content-Type header, I noticed that only the frame before-last is displayed in the tag, as opposed to the most recently sent one.

This behaviour is very annoying, as I'm only sending updates when the image changes to save on bandwidth, which means that the wrong frame will be on screen while I'm waiting for it to update.

Specifically, I am using Brave Browser (based on chromium), but as I have tried with both "shields" up and down, I assume this problem occurs also in other chromium-based browsers at least.

Searching for the problem yields only one relevant result (and many non-relevant ones) which is this HowToForge thread, with no replies. Likewise, I also thought the issue is to do with buffering, but I made sure to flush the buffer to no avail, much alike to the user in the thread. The user does report that it works on one of their servers though and not the other, which then lead me to believe that it may be to do with a specific HTTP header or something along those lines. My first guess was Content-Length because the browser can tell when the image is complete from that, but it didn't seem to have any effect.

So essentially, my question is: Is there a way to tell the browser to show the most recent multipart/x-mixed-replace and not the one before? And, if this isn't standard behaviour, what could the cause be?

And of course, here's the relevant source code, though I imagine this is more of a general HTTP question than one to do with the code:
