The VI contains a for loop. In case of error i want to stop the for-loop.
So i unbundle the error line. and make a while-loop round the for-loop.
Setting is stop on error .
My issue: How to get out the value from the for-loop?
* Shifting register is not really working
* indexing cannto be configured (due to error line is a cluster?
Found the solution:
For-Loop --> right click on border --> add condition terminal --> connect this with the unbundle element
Depending of LabVIEW version you are using you can do it differently. Conditional for loop was introduced sometimes at LabVIEW 8.6, before that version the only solution is to use while loop instead of for loop.
No need to unbundle the error cluster, it can be wired directly into stop terminal.
Error wire is also can be wired directly into boolean nodes in the latest versions of LabVIEW.

I'm using selenium, pyautogui, pywinauto to automate the desktop app. I'm automating settings app. And based on the user's input value I'm trying to change the value of the current brightness of the computer. but it keeps on showing this error.
The most important part is I wasn't getting the error 3 weeks ago and everything was working fine but yesterday when I run the script it started throwing the error.
The complete error I'm getting is-
ctypes.windll.user32.GetCursorPos(ctypes.byref(cursor))
ctypes.ArgumentError: argument 1: : expected LP_POINT instance instead of pointer to POINT
Some part of the script where the process get stuck and starts throwing the error. the script stop running at the 3rd line...
slider = content_of_page.find_element_by_id("SystemSettings_Display_Brightness_Slider")
slider.click()
pyautogui.dragRel(args.value, 0, duration=1.0, button='left')
pyautogui.click()
I'm using pyautogui=0.9.47
I also had the same issue and reinstall did not help. I found solution in: https://github.com/asweigart/pyautogui/issues/353
After installing pywinauto==0.6.6 all work ok for me.
I had the exact problem just right now.
I fixed it by un- and reinstalling pyautogui and pywinauto.
The problem persisted after reinstalling pyautogui, but was fixed after reinstalling pywinauto. So I am not sure if you need to reinstall both or just pywinauto.
Hope that helps!

I made a code through python to operate a preview of my PiCamera, I have set the time to 10 seconds, then automatically turns off. However I am unsure how I would be able to have a keystroke to stop the camera and return to the previous screen?
At the moment I am able to view for 10 seconds, and nothing else, the usual ctrl-c and various other keys does not work.
How would I be able to integrate a keystroke into the code following to stop the script and return to normal screen?
from picamera import PiCamera
from time import sleep
camera = PiCamera()
camera.start_preview()
sleep(10)
camera.stop_preview()
Subprocess module you can check on the official page:
https://docs.python.org/2/library/subprocess.html#subprocess.Popen
A possible way to implement with subprocess.Popen is here on SO:
Controlling a python script from another script
Another possibility is to use multiprocesses or multithreading module. For instance creation of a thread can be done and you can take care of an ID :-)
All the possibility will lead you to learn a bit more of python!
My better suggestion will be to create easily a thread (https://docs.python.org/3/library/threading.html --> here for python 3), get the ID and leave it run.
If you want to terminate the camera running, then terminate the thread :-)
I'm learning to use the Mule Anypoint Studio software and things have been going okay so far. I'm using the Debugger to learn a lot. Right now I have an Expression Component with some looping inside of it and I'd like to be able to debug the code as it iterates through the looping inside of the Expression Component. Is this possible? I can't figure out how to get the debugger to dive inside of an Expression Component, if it's possible at all.
Thanks!
Did you try step-in ? It take you inside of flow unless you reach up to smaller unit. You will able to evaluate expression and trace properties value but won't be able to take debug pointer till that point.
While debugging my React Native app in Chrome, I'm often unable to set breakpoints in the Sources tab. When I click on a line of code to add the breakpoint, a breakpoint is added instead to the next function declaration line in my module.
This doesn't happen in all of my source modules, but often enough that it prevents me from debugging efficiently.
I'm currently using RN 0.22 but this has been happening on older versions of RN as well (e.g. RN 0.18).
This problem maybe caused by babel. When use normal function and arrow function together, it happened.
"sourceMaps": "inline" in .babelrc fixed this for me.
I've only experienced this issue under the following conditions:
1) The .js file contains multiple functions, and
2) Attempting to set a breakpoint within a function that is not the last function in the .js file
So, a partial workaround is to move a function such that it is the last function in the .js file. Or, you could assign a single function per file. Either way, you will be able to set breakpoints.
This is far from ideal, but it's the only "solution" I've found so far.
I had the same issue, and I have a cozy solution for now :
I put the word "debugger" in the file which I want to debug.
I refresh the browser to see that it stops.
after it stops, I can add as much as breakpoints as I want and remove the "debugger" word from file
Try this package
https://www.npmjs.com/package/react-breakpoint-fix
just install the package and run react-breakpoint-fix from the terminal.
This fixed it for me. I'm using react-scripts#3.x
The Problem: I'm using Appium's python client to send_keys to a WebElement.
And Instruments decides it shouldn't tap certain keys sometimes.
This is a pain when I'm trying to do things like login. I need to be able to reliably type or programmatically set values on input fields.
This is (more or less) what I'm doing, and here's the gist of Instruments complaining about it:
el = driver.find_element_by_xpath('//UIATextField[1]')
el.click()
el.send_keys('ABCDEFGHI')
All pretty standard. And it usually works
But usually isn't cutting it. I need something solid.
Possible Solutions?
I think I can make send_keys work if I do some sort of try/retry if I get a WebDriverException back.
But what would be really cool is if I could set the value of the element through a JavaScript execute_script - or better yet - a selenium python binding!
I don't know JavaScript, and I've already tried searching for how to set the value on the object without doing sendKeys but I've come up blank.
Any ideas would be really helpful. Thanks!
Solution below:
# Get the element
el = driver.find_element_by_class_name('UIATextField')
driver.execute_script("au.getElement('%s').setValue('%s')" % (el.id, 'ABCDEF'))
# At this point, the keyboard is opened and the text is instantly entered.
