QUESTION
I have an unbound datagridview, set the option to allow user to add row to True, and all I want is that once I "complete" a row, the datagridview automatically should create a new empty row, so I set the method
...ANSWER
Answered 2022-Mar-25 at 14:32Is there some reason you do not use a DataSource
for the grid? Then you could simply add the row to the DataSource
.
If you insist on manually adding the rows, then the problem you currently have is that the code is never “adding” a new row to the grid. The code simply uses the grids CurrentRow
to set the values. This may work but the grids “new” row will not get created.
It is questionable to use the grids CurrentRow
in this manner... So instead of using the grids CurrentRow
for this, I suggest you “add” a new row in the RicercaxCodiceArticolo
method. Something like below should add the new row and the “new-new” empty row should be at the bottom…
QUESTION
I am developing a Laravel management application with Yajra datatables.
So I have various tables, and in particular in the user table I need to change the user's status (active / inactive) via ajax request by simply clicking a button or ticking a checkbox. This is my first time using ajax and datatables, and I have no idea how to achieve this ... is it possible or are there better / quicker ways to do this?
I accept any advice or suggestion
My code:
- controller
ANSWER
Answered 2022-Mar-11 at 14:17Create a form inside your table and create a custom function in the select
(I assume you want to change it using a select)
After that you want to create a ajax request like this:
$.fn.myFunction = function(form){
//put the form elements in an array
id = $(form).serializeArray();
//Get the value of the first index(the id)
id = id[0]["value"];
$.ajax({
// Post method
type: 'POST',
// Url to the route
url: "/ajax/myfunction",
headers: {
'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
},
// Data to submit to the function
data: {
//CRSF token for laravel form validations
_token: $('meta[name="csrf-token"]').attr('content'),
id: id
},
success: function(response){
//if request is made successfully then the response represent the data
$( "#result" ).empty().append( response );
}
});
}

QUESTION
in my program I defined a data type called Lyapunov_orbit
that contains 8 fields, then I used it to read data from external .txt file (see below where I report only a few lines for convenience because the file has about 4000 lines). I need to perform some operations by using such structure (as to find minimum and maximum value of an array) but to handle it I had to declare an "auxiliary" variable called vec_J_cst
because if I try to directly use my data strucutre, I get some errors (the structure-name is invalid or missing).
Here is the .txt file:

QUESTION
I'm a beginner at R and I've been having some trouble with this specific data set.
I've downloaded the newsatlasbr package (https://github.com/voltdatalab/newsatlasbr), which was "created to give easier access to the datasets of the News Atlas project, which is an initiative that researches and maps news organizations in the Brazilian territory".
When I run organizations_state(uf = "All")
, I have access to data from news vehicles from every single Brazilian state. The generated dataframe (let's say, vehicles <- organizations_state(uf = "All")
, comes with columns such as :
ANSWER
Answered 2022-Jan-27 at 21:40A dplyr approach
We need to first extract the desired list-columns with pull
.
Second, we can map
regular dplyr
filter
to get only elements with channel_id == 1, then select
the link column,
Finally, bind the elements back together with bind_rows
.
If we would rather have a vector of links instead of a data.frame, we can replace bind_rows
with unlist %>% unname
QUESTION
I need help rearraning results from database into array of array for duplicate rows, this is an example of what i get , like 2 results , i have alot of results and need it to group by rota,clientes and artigos. i need to do this in api using php.
...ANSWER
Answered 2022-Jan-28 at 11:35In Javascript, you could take an array of wanted groups with
- grouping property,
- an array of properties of their grouping level,
- a wanted key name for the children of this level of grouping.
Then create a nested object (this is the same structure of every level) with a property _
which keeps an object for the nested levels and an array of the children of the actual level.
To get a result take only the _
property.

...ANSWER
Answered 2021-Dec-30 at 13:10With a variable array of columns you need to group in hierarchical order, you'll certainly want a recursive solution to this problem. For each step in your recursive calls, check to see if a particular grouping level exists yet, and if not, then initialize it. Group using associative arrays for your items, then convert to flat arrays after. It's very simple conceptually, although perhaps a little confusing to look at:

I have this VBA code that was working fine until today, now Internet explorer is not opening the url in the right way (I think it is too old)

which is masking all potential errors.
At first glance I can see you trying to use methods of MSHTML.HTMLTable
on a WebElement
, which won't work.
Use the in-built methods e.g. Dim myColl As Selenium.Table
then use the .ToExcel
method to write out the table to a specified range in one go.
FireFox is no longer supported (not since a very old version) so forget about that. You do have a choice of several other browsers but Chrome should be good enough.
Make sure your ChromeDriver and Chrome browser versions are compatible.
