QUESTION
I have a form on my website where the content will be saved to google forms. It worked earlier today, but suddenly I got an error (error code 400) when submitting. I don't know why this happens. It worked 1 hour ago. Haven't changed any code in the form as well. I deleted my responses between the last successful submit and the first error. Could this be the reason for the errors? Appreciate all help

QUESTION
I'm trying to use a custom Angular component library which I´ve made in an Electron project. I have already use this library in an Angular project and it does work correctly, so I'm assuming the problem is something related with the library and Electron.
After installing all dependencies and setting all up, I can start the app, but it starts completly white as if nothing is loading. Only one error at console:
After some research, I couldn't find any workaround as the error isn't descriptive.
If there is any file or setting that can help for the answer, ask for it in a comment and I'll edit the post to add it!
[edit 1]
After some tries I ran the angular project by itself and it didn't work either. Same error.
Also, by removing the CustomLibraryModule from my app.module.ts fix the error. But i need to use the library as a mandatory requirement.
ANSWER
Answered 2021-Apr-23 at 07:57maybe there are problems with the angular version. I would first try to use the same angular version for the project with which the components library was created
QUESTION
I have a very large excel file of 1000+ street intersections that I need to find the Longitude and latitudes for and then write that info to file/list for a different program to consume.
What I'm stuck on is on how to build a more efficient script using multithreading/multiprocessing, I have looked through other questions/post but I'm i find it all a bit confusing. The code below takes roughly ~ 10+ mins. Any help would be great.
...ANSWER
Answered 2021-Apr-09 at 21:57The problem does not comes from Pandas but ArcGIS().geocode(address) which is insanely slow. Indeed, on my machine, this line takes 400 ms/request. Each request send a slow network query to the online ArcGIS API. Using multiprocessing will not help much as you will quickly reach additional limitations (limited rate of API request, saturation of the website). You need to send batch requests. Unfortunately this does not seems supported by the geopy package. If you are tied to ArcGIS, you need to use their own API. You can find more information about how to do that on the ArcGIS documentation.

QUESTION
I have been trying to save register.txt contents to my main file and put it into a struct, it works until I try to print the actual struct. Somehow it doesn't go into it, like it does not save as an array, so the print I have written on the last line prints out what is on the register.txt file but the code does not save its contents as an array/struct in the main file. Any help is appreciated, thank you.
...ANSWER
Answered 2021-Jan-07 at 23:56There are many reasons your code could fail: you should add some error testing.
- test if
fopen()succeeds and report failures with an explicit message that includes the filename. - test for
fscanf()failure and report those.

so as stated iam a total newbie beginner at programming, iam starting off my practising with making a little quizz program.
Iam trying to return people to the same question if they answered wrong. ive tried putting it all in a while loop and making the while loop run untill the correct answer is done. but when i do while loops i cannot point at my "ask" variabel that contains the user input. if this makes sense i hope you can help :)
heres my code:
...ANSWER
Answered 2020-Nov-10 at 15:11This is not what your while loop is doing:
Your while loop will stop at the moment the user gives a input that is between 1 and 3 ( the length of your answers array.)
it means your while loop will execute again only if the user gives a input like 5 or 0.
But you're almost there.
If you want your QUIZ to repeat the answer just modify your main function to something like
QUESTION
I am new to Flutter/Dart and I am trying to figure out how I can display something in a title:text dependant on the value of dropdown-menu choice. I have created a ListTile with a DropDownButton which has items stored as Strings. I want to display a number dependant on the string chosen in the DropDownButton. Can I read the value from the setState, and output a value based on that string? Or is there a better way to do this? I've been googling for about 2 hours and can't seem to understand it.
...ANSWER
Answered 2020-Oct-14 at 13:30I'm not exactly sure what your problem is but here are what I can think about:
- To reference a variable just use its name, and here you have to check for nullity so you can use the ?? operator
- To display a number then a string you can use dart String interpolation which will lead you to do
'$title:$text - Note that variable should use the lowerCamelCase naming, not UpperCamelCase. So in your code

Finally, here is your code with all of this together. This might not be exactly what you want but you should be able to expand on this.
QUESTION
I am trying to make my app calculate something when the user has inputted a value. I am using a "onChanged" function within the TextField to set a string to the value inputted. Then I am trying to parse this to an integer, but I am receiving that it can't be null and crashing my app. How can I make my tryParse execute after the onchange, and make it available to the rest of the app? At the moment it only makes it available inside that TextField if I put it there, and if I put it outside my class it crashes the app cause the int is null.
