Create fully functional virtual Kubernetes clusters - Each vcluster runs inside a namespace of the underlying k8s cluster. It's cheaper than creating separate full-blown clusters and it offers better multi-tenancy and isolation than regular namespaces.

QUESTION
I have a program that takes sheets of mixed data from an Excel file and places it into a SQL Server Database. It already runs relatively fast, but I wish to make it more dynamic. Currently, I use OleDb
to select data from an Excel file and Entity Framework Core
to add the data to a SQL Server Database.
I have a class for each sheet in the Excel file. The class I'm going to use as an example here is my vHost
class. After I use OleDb
to select all the data from the vHost
Excel sheet (using SELECT *
) I place the data into a Data Table
object. I then go through each column in the Data Table to create a List
object of the column names in the Excel sheet. These are crucial for the program to understand where to insert data into the SQL Server Database. Once the list of column names is created, the program then indexes through all the data in the Data Table
and creates a vHost
object to place in the SQL Server Database. This is the portion that I wish to make more dynamic.
In order for the program to decide what object in the vHost
class to set some data equal to, it compares an index in the Column List to a static string. If the column index we are on is equal or contains the same string for the column name, the object correlating to that in the vHost
class is set equal to some data. This portion is long and grueling to type, but it allows me to create a program that will run with minimal errors.
Here is the code I have for the vHost
section:

Answered 2020-Aug-10 at 08:49Based on your description, you want to move data from excel to sql server by using efcore.
I suggest that you can convert the datatable to the list.
Here is a code example you can refer to:

table (successfully) generated by D3.js from csv file loads at the bottom of body and below scripts tags. Hence I cannot select table for adding id, classes and more
I tried adding a table tag in the html with id and classes I need and forced the append to that but I got the newly generated table INSIDE the table tag in html.. and so still not selectable.
...ANSWER
Answered 2019-Apr-14 at 07:34Try just selecting your existing table instead of selecting AND appending it to the DOM:
var table = d3.select('#mytable');
Hope it helps.
QUESTION
I'm trying to create a table, populated by an ajax query where each row has a delete button next to it, so it can be easily removed.
However if I try to build the button inside an ajax query it doesn't seem to post correctly. To ensure it wasn't the code inside the jquery click I created this simple function
...ANSWER
Answered 2017-Feb-24 at 15:56Your "click" event handler won't catch buttons that are created dynamically by the ajax call. They don't exist yet when the event handler is called, so it ignores them. And since you didn't specify a type="button"
attribute for your dynamic buttons, they default to type="submit"
, which, if the button is inside a form, will cause your form to be submitted using a full postback when they're clicked (and there's no click handler to override this).
Use delegated event handling to get round this. You set the event on an element which will definitely exist when the event handler is called, and then tell it to delegate the events down to any elements which match the secondary selector at the time when the event fires. I don't know what element would be the lowest common ancestor of your buttons, so I've just used document
