QUESTION
I am using Paging Library 3 with a RemoteMediator which includes loading data from the network and the local Room database. Every time I scroll to a certain position in the RecyclerView, navigate away to another Fragment, and then navigate back to the Fragment with the list, the scroll state is not preserved and the RecyclerView displays the list from the very first item instead of the position I was at before I navigated away.
I have tried using StateRestorationPolicy with no luck and can't seem to figure out a way to obtain the scroll position of the PagingDataAdapter and restore it to that same exact position when navigating back to the Fragment.
In my ViewModel, I have a Flow that collects data from the RemoteMediator:

QUESTION
im developing a private c++ tool for month now. And now everything seems to be lost because i wanted to use Github. I really hope that i can restore it with someones help.
What i did:
a few weeks ago i played around with github in Visual studio. I was able to commit a lot of files to my private Github. I dont know how Github works in detail so please be patient.
After that i just did not use it anymore as i just wanted to know how it might work for a later step.
I started recoding a lot of stuff and changing almost everything on my tool. Today i wanted to commit those new coded project to the github repository.
I thought about deleting the current github content bforehand and did it so .. so i went on github.com and just deteled my "test commit" from weeks ago.
After that i went back to Visual studio and tryed to commit my new project. That it started to pull and push or something and after that everything what was "new" has been deleted.
Please tell me, am i able to restore my project in any way ? I really start to cry if all my work is lost.
Thank you
EDIT:

Answered 2021-Jun-09 at 18:36Alright after a short chat we were able to recover the deleted files. Here are some points to follow that this doesn't happen again in the future:
- Use one git repository for each of your projects.
- Never delete files from within github. Just delete them locally. Git will notice that and you can commit those deletions like any other changes to your files.
- Commit and push on a regular basis, not only once every month. Commits are basically little recovery points that you can go back to if you mess something up.
- Please read up on how git works and what commits and branches are.
- Configure your Visual Studio to not automagically perform destructive git actions (not sure how this happened in the first place, this is definitely not the default setting).
QUESTION
I have a jqgrid with a subgrid. I made a few columns in the parent grid and subgrid as frozen. Frozen columns on subgrid works fine, but it does not work on the parent grid.
When I disable the subgrid by setting subGrid as false, frozen rows works perfectly on the parent.
Is there anything that I am missing which stops the frozen columns on the parent grid from working?
Here is my jqgrid:

Answered 2021-Jun-07 at 07:42In Guriddo jqGrid subgrid can not be used when frozen columns are on.
Here you can read all the limitation of Guriddo jqGrid. We do not know how this is in free-jqgrid.

QUESTION
I am trying to pass data from controller to GQ grid. I have done implemented the SQL operation - selecting a row- in another file and returning a object of list type List
to the Controller. I implemented the controller of type JsonResult
which returns the data in json format. The controller is using [HttpGet]
Attritute. I have attached code of my controller, html, js file and screenshot of the issue. The Google Console is not showing any problem. The table is getting ready, but the table data is showing. I guess there is the issue with "passing the data" properly. It would be very helpful for me if anybody could just check my code and let me know where I am getting wrong.
Additionally, is there any software, where I can check where the issue is coming while connecting to server, because in this case Google inspect tool is not helpful at all.
In my controller, by using breakpoint I have checked that in Integrations value = db.GetIntegrationRow();
I am getting a correct value in value

I have used JQGrid to get the data from the controller which uses "GET". But, still I'm getting a blank table. I have also tried to apply breakpoints and check whether my variable "details" inside "Detail" Method getting value or not. It worked fine.

QUESTION
I am learning C programming from "Learn c the hard way by Zed Shaw". He asks the learner to try and break their own code.
So I tried the following C code and thought printing more values that I gave argv will break it but it did not until later.
...ANSWER
Answered 2021-May-30 at 09:48A segmentation fault happens when the code try to access a memory region that is not available.
Accessing an array out of bounds doesn't means that the memory before or after the area occupied by the array is not available: The compiler or the runtime usually put all varibales or data in general in a given block of memory. If your array is the last item of such a memory block, the accessing it with a to big index will produce a Segmentaion Fault but is the array is in the middle of the memory block, you will just access memory used for other data, giving unexpected result and undefined behavior.
If the array (In may example, but valid for anything) is written, accessing available memory will not produce a segmentation fault but will overwrite something else. It may produce unexpected results or crash or segmentation fault later! This kind of bug is frequently very difficult to find because the unexpected result/behavior looks completely independent of the root cause.
