How can i iterate both the tables and then get the result?

QUESTION
I have this piece of code which computes the difference between the rows of two selected tables and display the result on click of button. How can I display the result in a pop up? Basically I want the resultant table to come as popup, so that when we close the popup the tables checkbox are again reset.
Edit: I tried using modals but it seems to be not working. Can anyone please help where I am going wrong
...ANSWER
Answered 2021-Apr-26 at 14:19You can use modals to display your differences between your tables as a popup when they selected. Assign modals' close button as a reset button as well via JS.
modals: https://getbootstrap.com/docs/4.0/components/modal/
Edit:
I couldn't find the line for calling your js file in your code. Can you add this line to the end of your html-body section?
You can add a console.log()
line to your js file, so you can see if your js and html files are connected or not on the browser. (via insperctor-console)
Also, I couldn't find the line that you're activating your modal. You should change its class list. fade
means it will not display on the browser. You should remove it and add show
instead.
Edit-2:
I am not familiar with $
so I am adding the JS which is working. Please try the below things and if there will be a problem, edit your code below and leave me a comment.
in your js file, follow the steps I wrote. You should see an alarm when you click your modal button. You need to fill it up:
QUESTION
I have a matlab script that calculates the hourly thermal load of a refrigerated transport trailer for a day. The ambient temperature used is an array of hourly temperature data for a particular year, thus 8760x1 elements. I want create a for loop or some sort of iteration that picks every 24-hour data from the ambient temp array, thus 1:24, 25:48, etc; perform the calculations and store it in a matrix. So eventually it will result in a 24x365.
...ANSWER
Answered 2021-Apr-05 at 10:28As mimocha suggested in the comments, you just want to reshape your 8760x1 matrix of hourly temperatures into a 24x365 matrix, where each column contains the data for one day and each row contains the data for every hour within that day.

QUESTION
I guess my code has many weak points, so please feel free to share any thoughts. My main question btw, is that when I'm trying to do the following, and at the end, when I'd like to wait all my tasks (by using Task.WaitAll) to get completed to examine if there were any exceptions, will it really make any part of the code to run synchronously, just because the lack of an 'await' operator?
...ANSWER
Answered 2021-Mar-27 at 14:43will it really make any part of the code to run synchronously, just because the lack of an 'await' operator?
Yes. The Main
method will run synchronously. This won't really matter because it's the Main
method, but if you want to asynchronously wait for the tasks to complete, use await Task.WhenAll
instead of Task.WaitAll
. The asynchronous approach has an additional benefit in that it doesn't wrap exceptions in AggregateException
.
On a side note, use await
instead of ContinueWith
.
QUESTION
In my generic base repository I have the following simple method for removing an entity from database:
...ANSWER
Answered 2021-Jan-05 at 14:45Added
, Modified
and Deleted
are pending states, indicating what EF Core will do with that entity when SaveChanges{Async}
is called. ChangeTracker.HasChanges()
returns true when there is any entity entry with such state.
By default (acceptAllChangesOnSuccess=true
parameter of SaveChanges{Async}
), after successful SaveChanges
these states are updated to reflect the permanent (database) state of these entities. Added
and Modified
become Unchanged
, Deleted
become Detached
(and entries are removed from the change tracker) and ChangeTracker.HasChanges()
returns false.
You can change that by passing acceptAllChangesOnSuccess=false
to SaveChanges{Async}
, in which case you'll see the pending states, but then you should not forget to call ChangeTracker.AcceptAllChanges()
, otherwise the next SaveChanges{Async}
will try to reapply them in the database (and most likely will fail).

QUESTION
Working sample at the end of this article (I kept all things I tried [reason for long article], so that others could benefit from it later)
I am trying to write integration tests for my EF Core 3.1 class library. As unit test framework, I have used XUnit and followed guide from Microsoft: https://docs.microsoft.com/en-us/ef/core/testing/sharing-databases
Here is how the setup looks like (it's a bit longer because I am actually creating a database in my SQL Server in case I need to see the real result from tests output):
...ANSWER
Answered 2020-Dec-22 at 12:25Robert, Glad It helped! As per your request, I re-submit the answer for anyone that could find this answer helpful as you.
I learn the hard way that trying to share the entity framework database context over IClassFixture
or CollectionFixtures
would eventually end up in tests being polluted with another test data or deadlock/race conditions due to the parallel execution of xUnit, entity framework throwing exceptions because it already tracked that object with a given Id and more headaches like that.
Personally, I would kindly recommend that for your specific use cause, stick the database context creation/cleanup within the constructor/dispose
alternative such as:
