QUESTION
Shall we use the inline CSS style also in React / Next.js app, to unify code between the two projects?
Like this?
...ANSWER
Answered 2021-Apr-21 at 19:37I suggest looking into react-native-web
for proper code reuse as it allows using the exact same StyleSheet objects. Sharing CSS with a regular React web app directly must be tricky, because of the difference in supported CSS ruleset, flex behaviour etc.

Who can tell me What the problem?? Is there mistake in my xml code?
Java code
...ANSWER
Answered 2021-Apr-17 at 14:24It looks like you're adding the data to the drawerStarList
list, but not telling the adapter that you've done so. Until you tell the adapter of the change (by calling notifyDataSetChanged()
on it), it won't repaint the UI for the list.
So typically this would look something like:
QUESTION
I need to add a new foreign key to my table called starList
. It currently does not have a foreign key relationship with the table called planetList
.
So I ran this command:
...ANSWER
Answered 2020-Sep-02 at 15:12You need to check your data in both columns.
There is a value in the column of foreign key table whose associated value doesn't exist in the primary key table.
You have data in starlist.planetid which does not match/correspond to planetlist.planetid.
Both of them need to be the same with values values. It would be better to truncate them and then try creating the contraint.
In short, there is violation of referential integrity rules.
If this is the case, keep in mind to create foreign key before populating the tables.

QUESTION
I have an Entity Framework controller that has been using the method below successfully. However I recently updated my project to use .NET Core 3.1 and it must've broken something.
I am now getting this error:
FirstOrDefault()' could not be translated. Either rewrite the query in a form that can be translated, or switch to client evaluation explicitly by inserting a call to either AsEnumerable(), AsAsyncEnumerable(), ToList(), or ToListAsync()
I did some research, and some people say not to use GroupBy
extension which I do in the query below. I tried to take it out, but that just generates more errors.
I also went to this:
But I couldn't figure out how to fix my complex query below.
Honestly, I'm not sure why it's failing or how to properly fix it.
Does anyone see anything wrong?
Thanks!

QUESTION
I have these 2 objects, a dictionary, and a method
...ANSWER
Answered 2020-Apr-09 at 22:14I will explain why it is forbidden by C#. Let's define a second subclass public class BlackHole : Thing {}
Now if you could cast the dictionary of stars into a dictionary of things as you try var dicThings = (Dictionary) dictStar
You could write later dicThings.Add(5, new BlackHole());
, but there is an issue with that: the runtime type of dicThings would still be a dictionary of stars... containing a black hole.
Solution:
You can turn your method into a generic with a constraint on the type, as such listBoxAdd .... where T : Thing
Here is a full example code:
QUESTION
I need to do some natural language processing that requires me to find all sentence segments that contain a certain search term. To do this, I want to get all the words between any punctuation marks that contain the search term. For example, I can easily get the words before and after the search term using the code below. I could also write more complicated logic that break it down, but I am trying to figure out if I can do this using one line of regex.
I've tried a bunch of different combinations of regex lookahead and lookbehind patterns with various results but none of them achieve the results I'm seeking. I can get everything between two of the same punctuation marks, e.g. everything between two periods (i.e. starlist = re.findall(r'([^.]?Star Trek[^.].)',s) The problem seems to be when I try to use groups, e.g. [.;:,]? Anyone know how to solve this problem?

QUESTION
I am beginner in Thymeleaf, I have my class Star
which has a list of another class called Part
:
Star class:
...ANSWER
Answered 2017-Aug-14 at 14:26The part
and rep
fiels are lists, so expression like ${star.part.rep.note}
is meaningless. You could have zero or many Part objects inside the list so you must be specific from which one do you want to extract data. This also applies to list of Rep objects.
So if you want to get data from specific elements of those collections you have to use indexed access. E.g. get note from first Rep of first Part:
