I was trying to automate my classes so that whenever I run my command in ubuntu it launches the session.
I was able to lauch the window upto the subject but the issue I am facing is,I can't get an exact link for blackboard session as it keeps changing for every sesson.
And when I tried to copy the link address it copied "javascript:void(0);".
I written this code in c++.
Can someone guide me through this?

Lets rewrite my problem:
I will not provide any code because it would cost me too much payed worktime to extract the certain code samples from my project. On top of that i think its not code related, but browser/browser-security related.
When Chrome (Or Edge) tries to open an external application (No matter what application), an alert box pops open that asks if Chrome should open the external application.
Regardless if i open it or cancel the alert box, at this very moment all socket.io communication from my backend server isnt received anymore.
Before trying to open the external application or after a page refresh, everything runs fine.
Thats my problem, i apologise if some may not be able to understand the problem without me providing any code samples. I just hope someone comes by who already had that kind of problem and knows how to fix it.
I managed to go around this problem. I open my link to the external application directly in a new tab, which transfers the Alert Box to the newly opened tab.
The alert box seemed to have caused the error. When it opens in another tab, my main tab can still receive the backend emits.
Thanks for everyone who stumbled over this^^
Whenever I update the code on production the changes can't reflect without hard refreshing (ctrl+F5) the page. So, Is there any way by coding I can handle this problem because the end user doesn't know these things.
Pls suggest. Currently, I am developing using the Dot net core for API's and reactJS as frontend.
You can implement PWA, whenever a new version/file is available it automatically downloads. In PWA you can add an alert like "App Update is available" Here is the reference for ReactJs: https://dev.to/daniellycosta/showing-new-version-available-notification-on-create-react-app-pwas-3jc9
Is there any configuration in react-navigation for screens I only want to display once during the life time of the app? For instance, once the app is installed for the first time, I want the help screen to appear.
If no configuration is available, then what is the best way to do it? My idea is to save a variable locally and set it once the help screen has been displayed. Once the user opens the app again this variable will be checked and based on the that the next screen will appear. The problem here is that if the user erased the app data (cache and all) then the help screen will appear again even if he is not a first time user.
Any suggestions?
People change their mobiles and sell the old ones. A new user might install the same application on the same mobile but that user should also see the help page. You can achieve this using 2 methods, one would be server based and one would be local mobile based.
1) Server Based
When the user registers or log-ins for the first time show the help page and store that the user has seen the help page on your server. Next time the user reinstalls the application on a new device or the same device check for that information and do not show the help page.
2) Local Based
Use React Native's AsyncStorage and mark the user as help seen. When the user logs-out of the application make sure to remove that key from AsyncStore so that a new user can see the help page.
My thoughts would be you use the local app based method and let the user see the help page everytime they clear their app data or reinstall the application because features change and you might also change the help page in future. So it is better to let the user see it more than once given that you give the ability to skip the help page as well :)
Using AsyncStorage is probably the best option since it will store data locally on the device and persist between sessions. However, AsyncStorage data will be erased if the user uninstalls an app.
You can persist data between app installs on iOS by using the Keychain, accessible in React Native via 3rd party libraries (https://github.com/oblador/react-native-keychain)
I don't believe there is any way to persist data between app installs on Android.
I try to figure out how to find and run an application on the users pc when you click a button on the website. I saw this feature on the Unity Assets Store Page. When you click there the Add to Downloads Button the Asset will be opened in Unity. Now I try this too. Therefor I searched a bit and find out that you can do this with HTA? But I only found how to run a specific application like notepad but what is when i dont know the application path. How can I do that?
I am new here, but I have spent several days in and issue that I have not solved yet.
This is what I want to achieve:
I would like to redirect the console logs to a USB file directly.
I have a shell script to be launched automatically when booting the raspberry (this process works). The script executes a javascript file.
I need to remove the USB drive directly, with the raspberry pi still powered on, and the log file remaining in the USB drive.
This is what I tried:
Redirect it directly with expression like: "sudo node node_modules/sensortag/.. > /media/USBname/Data.txt" (it shows me 'access denied'), but the first part of the expression works fine if executed without the redirection part.
I have tried to change permissions for USB directory, and still the same problem.
I have tried to execute the previous command in the terminal (not with the script) and it only works if "sudo su" command is entered before the instruction (but it does not work only with "sudo" command and I do not know how to insert "sudo su" command in the script). I have tried many different options.
Do you know why I have this error? and could you tell me how to solve it?
Another option that I can try, but not yet because I do not have it clear, is to modify the javascript file to redirect the console log to a USB file. Could you tell me how to do it?
Thanks a lot. I have took a look to many different forum threads but I am not able to solve this problem. I hope you can guide me on it.
