QUESTION
How to make nuget package:moderenwpfui generate only needed language files.
The repository for this nuget package is https://github.com/Kinnara/ModernWpf .
When I generate my app, a lot of language files will be generated. Is there a way to generate only the language I need or preset the language file to the language I use?
The following are all the files generated in the Debug directory, the one without the suffix is the folder, the folder contains the dll library for the language files
ANSWER
Answered 2022-Feb-09 at 09:30Under Project>References you will find ModernWpf
and ModernWpf.Controls
. You need to set the property Copy Local
to False
for both of them.
Before you do that, backup these files and copy them manually to debug folder after doing the above steps.

...ANSWER
Answered 2021-Jun-07 at 16:57Couple things to check:
- Can you connect to MySQL outside of the script with the credentials
you provided (
mysql -u root -p
)? If yes, then there may be a configuration problem in your script to connect. If not, confirm MySQL is running, then re-check your password. If a potential password issue, may be worth restarting MySQL by addingskip_grant_tables
under your configuration file and restarting so you can log in w/o a password and reset the root password. - Did you modify the MySQL configuration in any way, specifically the
bind-address
? By default, MySQL sets this to 127.0.0.1, so you may want to try connecting with 127.0.0.1 instead of localhost. - If this is a non-Windows machine, is /etc/hosts configured properly for localhost (ex:
127.0.0.1 localhost
)?
I use a different method to connect to MySQL via Python, so I am not as familiar with sqlalchemy.
QUESTION
I want to download pdf from url using ok HTTP in kotlin. I didn't find the proper solution in coroutine how it be done through. After downloading i want to store in device and show in pdf viewer. When user close the activity the store file automatically delete form internal storage. Does anyone know how to do that. Thanks in advance
...ANSWER
Answered 2021-May-10 at 12:08You can basically save your file to your download folder.
what you have to do is; first add read, write permissions to yor manifest file,
Android defines the following storage-related permissions: READ_EXTERNAL_STORAGE, WRITE_EXTERNAL_STORAGE, and MANAGE_EXTERNAL_STORAGE.
then you should use content resolver for android version higher than 10. for example
QUESTION
I have a User object which has a a profilePicturePresignedUrl property. The value of the profilePicturePresignedUrl property needs to be computed using a service.
It would seem that the most efficient way of doing this would be to create a method in the User entity class that would inject the required service like so:
Entity/User.php
...ANSWER
Answered 2021-Jan-09 at 20:12Entity listeners are defined as PHP classes that listen to a single Doctrine event on a single entity class. For example, suppose that you want to prepare a specific entity whenever it is loaded from the database. To do so, define a listener for the postLoad
Doctrine event. See documentation.
This way, in your case, everytime you fetch a User entity from the database, the property will be initialized and ready to use everywhere in your code. Note that i do not recommand using this for heavy tasks because it will significantly reduce your app performance.
src/EventListener/UserListener.php

Before you all go on a rampage about how this is a duplicate question, I have spent two days working on this issue, watching youtube tutorials on asynchronous programming, surfing similar stackoverflow posts etc, and I cannot for the life of me figure out how to apply Asynchronous Parallel Downloading of files into my project.
First things first, some background:
I am creating a program that, when given a query input via the user, will make a call to the twitch API and download clips.
My program is two parts
1- A web scraper that generates a .json file with all details needed to download files and
2 - A downloader.
Part 1 works perfectly fine and generates the .json files no trouble.
My Downloader contains reference to a Data
class that is a handler for common properties and methods like my ClientID
, Authentication
, OutputPath
, JsonFile
, QueryURL
. It also contains methods to give values to these properties.
Here are the two methods of my FileDownloader.cs that are the problem:

I have been downloading zip file from server and extracting the zip file in local directory.
ie, /var/mobile/Containers/Data/Application/8A7B8DF1-AAA4-442E-99C9-82616FC3E192/Documents/assets.zip

From unzipped folder, i need to load index.html to WkWebView. But i could able to find folder but not able load into webview.
here is code for download zip file and extracting zip file in local directory:
...ANSWER
Answered 2020-Feb-08 at 09:51Generally to open a local file in WKWebView you can call loadFileURL(URL, allowReadAccessTo: URL)
on your WKWebView instance.
Edit after your comment:
If you know, that your index.html will always be in „build“ folder you can do:
