73,951,039 | 2 | null | 73,950,565 | 1 | null | I think there are a few ways to go about this, but here is a way to explain the useState in a way that fits the question. [CodeSandbox](https://codesandbox.io/s/usestate-array-qgdx3o)
For simplicity I made a Card component that knowns if it has been clicked or not and determines wither or not it should show the checkmark. Then if that component is clicked again a clickhandler from the parent is fired. This clickhandle moves the Card into a different state array to be handled.
The main Component:
```
export default function App() {
const [unselectedCards, setUnselectedCards] = useState([
"Car",
"Truck",
"Van",
"Scooter"
]);
const [selectedCards, setSelectedCards] = useState([]);
const addCard = (title) => {
const temp = unselectedCards;
const index = temp.indexOf(title);
temp.splice(index, 1);
setUnselectedCards(temp);
setSelectedCards([...selectedCards, title]);
};
const removeCard = (title) => {
console.log("title", title);
const temp = selectedCards;
const index = temp.indexOf(title);
temp.splice(index, 1);
setSelectedCards(temp);
setUnselectedCards([...unselectedCards, title]);
};
return (
<div className="App">
<h1>Current Cards</h1>
<div style={{ display: "flex", columnGap: "12px" }}>
{unselectedCards.map((title) => (
<Card title={title} onClickHandler={addCard} key={title} />
))}
</div>
<h1>Selected Cards</h1>
<div style={{ display: "flex", columnGap: "12px" }}>
{selectedCards.map((title) => (
<Card title={title} onClickHandler={removeCard} key={title} />
))}
</div>
</div>
);
}
```
The Card Component
```
export const Card = ({ onClickHandler, title }) => {
const [checked, setChecked] = useState(false);
const handleClickEvent = (onClickHandler, title, checked) => {
if (checked) {
onClickHandler(title);
} else {
setChecked(true);
}
};
return (
<div
style={{
width: "200px",
height: "250px",
background: "blue",
position: "relative"
}}
onClick={() => handleClickEvent(onClickHandler, title, checked)}
>
{checked ? (
<div
id="checkmark"
style={{ position: "absolute", left: "5px", top: "5px" }}
></div>
) : null}
<h3>{title}</h3>
</div>
);
};
```
I tried to make the useState actions as simple as possible with just a string array to help you see how it is used and then you can apply it to your own system.

73,951,908 | 2 | null | 73,948,057 | 0 | null | While doing my jogging, your question was bugging me, because of that `;` you showed at the end of both your good and your bad lines. Lines in a CSV file don't usually end in a semi colon!
My theory that your file was created by a process that wrote a semi-colon-separated-value file containing in column 0 the contents of each comma-separated-value line. That process had to escape double quotes in saw in the standard way, which is the put double quotes around the field and replace each double quote within the field with a doubled double quote.
If that theory is correct, what you can do is read the file twice, once as a semi-colon-separated-value file, and then the contents of column 0 as a CSV file.
Here's code that does exactly that:
```
import pandas as pd
import csv
import io
buffer = io.StringIO()
with open("file.mixed-sv", newline="") as mixed_sv_file:
reader = csv.reader(mixed_sv_file, delimiter=";")
for row in reader:
print(row[0], file=buffer)
buffer.seek(0)
df = pd.read_csv(buffer)
print("df:\n", df)
```
Given this input file, which I'm calling `file.mixed-sv` to highlight it's not pure CSV:
```
Fruit1,Fruit2,N,Notes,M;
Apples,Oranges,5,"These are apples, red, and oranges, orange",2;
"Apples,Oranges,5,""These are apples, red, and oranges, orange"",2";
```
my script outputs:
```
df:
Fruit1 Fruit2 N Notes M
0 Apples Oranges 5 These are apples, red, and oranges, orange 2
1 Apples Oranges 5 These are apples, red, and oranges, orange 2
```
Notes:
- `csv`- - `buffer.seek(0)`

73,953,718 | 2 | null | 73,953,389 | 0 | null | Your question sounds more about geometry than about coding. What exactly do you need?
Geometrically, if you want to check whether the point (a, b, c) lies inside of a (canonical) cylindrical surface
(x, y, z) such that {x^2 + y^2 = r^2, z in [zi, zf] },
simply check whether `a^2 + b^2 < r^2 and c in [zi, zf]` is `True`.
If the axis of your cylinder is not aligned to the z-axis, just bring the point (a, b, c) to a new system where the cylinder is in canonical form. In general, if the cylinder axis lies along the (unit) vector `v`. the angle with respect to the z-axis is simply `beta = arccos(v[2])` (`v` is already normalized!). Then you want to use [Rodrigues' rotation formula](https://en.wikipedia.org/wiki/Rodrigues%27_rotation_formula) with k = v and theta = -beta (note the sign) to transform (a, b, c). You should also check whether the rotated `p0` and `p1` already lie on the (rotated) z-axis, otherwise you should apply an additional translation to (a, b, c) before making the comparison.
If what you need is help coding this up, well, post your attempt and ask away :)

I am loading the `xml` files into an iframe from an anchor tag with a `target` attribute. e.g.:
```
<a href="${file.path}" target="displayFrame">...

What seemed to force the iframe to render the `xml` as plain text was to append an arbitrary (or even empty) query string parameter to the file URL, as follows:
```
<a href="${file.path}?" target="displayFrame">...
```
Note the '?'.
- `xml``'text/plain'`- `type="text/plain"`
Disclaimer: I am not sure exactly how or why this works; i.e., how it tricks Chrome into rendering the file differently, nor have I tested this extensively across other browsers.

73,954,291 | 2 | null | 13,305,457 | 1 | null | Contributing based on Jarek's answer. If you want tabs widths to change dynamically as you resize the TabControl as well, you can achieve this by implementing this on the TabControl Resize Event:
```
private bool doNotExecuteResizeEventAgain = true;
private void Tab_Control_Resize(object sender, EventArgs e)
{
if(doNotExecuteResizeEventAgain)
{
int tabWidth = ((int)(tab_Control.Width/tab_Control.TabPages.Count)) - 1;
doNotExecuteResizeEventAgain = false;
tab_Control.ItemSize = new Size(tabWidth, tab_Details.ItemSize.Height);
doNotExecuteResizeEventAgain = true;
}
}
```
The use of the variable `doNotExecuteResizeEventAgain` is because the ItemSize calls again the event Resize, so in order to stop it from cycling, I added that flag.

You can replace the Promise constructor with your own implementation that includes a stack trace for where it was created.
```
window.Promise = class FAKEPROMISE extends Promise {
constructor() {
super(...arguments);
this.__creationPoint = new Error().stack;
}
};
```
This will give you a stack trace of the point where any given promise was created.
Note that `.then`, `.catch`, and `.finally` all create new promises.
This will not function with Promises created by `async` functions, as those do not use the window's `Promise` constructor.
This can be used by reading the `promise` member of the `PromiseRejectionEvent`:
```
window.addEventListener('unhandledrejection', (promiseRejectionEvent) => {
console.log('unhandled: ', promiseRejectionEvent.promise.__creationPoint)
})
```
Which will print something like:
```
unhandled: Error
at new FAKEPROMISE (script.js:4:32)
at main (script.js:6:3)
at script.js:9:1

I am using SQL Developer Version [19.2.1.247] and connected to SQL Server Express 2017 on localhost.
Using jtds-1.3.1.jar downloaded from [sourceforge.net](https://sourceforge.net/projects/jtds/files/)
Follow these steps:
1.Download and unzip the file into the main SQL Developer directory (or the directory of your choice).
2.In SQL Developer go to Tools -> Preferences -> Database -> Third party JDBC Drivers. Click the “add entry” button
3.Navigate to the jtds-1.3.1.jar file.
4.Save and exit preferences.
5.Close and restart SQL Developer
Open “Add Connection” – there should now be a SQL Server tab.
Above steps are common and if you search on google you will get most of the sites having above mentioned steps.
THE PROBLEM WHICH I FOUND WAS THE DB PORT 1433 which is default port showing in connection dialoge need to be correct as your DB PORT.
I use below command to know my DB PORT.
```
sqlcmd -S myServer\instanceName -d master -h -1 -W -Q "xp_readerrorlog 0, 1, N'Server is listening on'"
```
based on result I found the port is 55993, see below image

73,956,592 | 2 | null | 73,955,430 | 0 | null | > DataTable show Ajax error while return Json in .NET MVC
First of all, you should check if in your browser log if you got the respose as expected. I think, your backend code looks alright. However, your `jQuery` snippet for getting `json` for `datatable` doesn't seems correct. You could follow below steps:
```
@{
ViewData["Title"] = "BindDataTableFromJson";
}
<table id="bindDataTable" class="table table-striped table-bordered dt-responsive nowrap" width="100%" cellspacing="0">
<thead>
<tr>
<td>Id</td>
<td>Name</td>
<td>Module</td>
<td>Product</td>
</tr>
</thead>
<tbody>
</tbody>
</table>
@section scripts {
<script src="https://ajax.aspnetcdn.com/ajax/jQuery/jquery-3.2.1.min.js"></script>
<script src="https://cdn.datatables.net/1.11.3/js/jquery.dataTables.min.js"></script>
<script>
$(document).ready(function () {
$.ajax({
type: "GET",
url: "/StackOverFlow/GetProg",
success: function (response) {
console.log(response);
$('#bindDataTable').DataTable({
data: response,
columns: [
{ data: 'bookId' },
{ data: 'name' },
{ data: 'module' },
{ data: 'product' }
]
});
},
error: function (response) {
alert(response.responseText);
}
});
});
</script>
}
```
Point to remember, while define your `column property` in `datatable` for example `bookId`, `name` must be in `lowercase` otherwise table will not traced the data accordingly. Furthermore, backend data should be same, case doesn't matter for that.
```
public class Prog
{
[Key]
public int BookId { get; set; }
public string Name { get; set; }
public string Module { get; set; }
public string Product { get; set; }
public string Segment { get; set; }
public DateTime Date{ get; set; }
}
```
Entity Model should have `primary-key` for instance `BookId`.
```
[HttpGet]
public IActionResult GetProg()
{
var listProg = _context.Progs.ToArray();
return Json(listProg);
}
```
This controller will fetch the data. You can use `ToListAsync` that will work without issue as well.
public IActionResult ViewProg()
{
return View();
}
This controller will load the view

If you want to make DateTime as Nullable then you can do that in database like below:
[](https://i.stack.imgur.com/3dkhz.png)
Besides, In Entity Model, we can deifne a property as nullable by putting `?` in it. Like below:

public DateTime? Date{ get; set; }

The Android community offers many Java libraries that you may want to use in your app. These Java libraries are often packaged in `.JAR` (Java Archive) format, but you can package a `.JAR` it in a Java Bindings Library so that its functionality is available to Xamarin.Android apps. The purpose of the Java Bindings library is to make the APIs in the `.JAR` file available to C# code through automatically-generated code wrappers.
Xamarin tooling can generate a Bindings Library from one or more input .JAR files. The Bindings Library (.DLL assembly) contains the following:
- -
The generated MCW code uses JNI (Java Native Interface) to forward your API calls to the underlying .JAR file. You can create bindings libraries for any .JAR file that was originally targeted to be used with Android (note that Xamarin tooling does not currently support the binding of non-Android Java libraries). You can also elect to build the Bindings Library without including the contents of the .JAR file so that the DLL has a dependency on the .JAR at runtime.
For more information, you can check: [Binding a Java Library](https://learn.microsoft.com/en-us/xamarin/android/platform/binding-java-library/) .

Just print your label twice, once an empty one with blanks and then another one with no fill and border. You might have to find the correct amount of blanks, but in my case it worked without problems and with a proportional font.
So with the code from the linked thread the solution would look like this:
```
#Create dataframe
countries <- c("Mundo", "Argentina", "Brasil", "Chile", "Colombia", "Mexico", "Perú", "Estados Unidos")
countries <- rep(countries, 120)
vaccinations <- data.frame(countries)
vaccinations$countries <- factor(vaccinations$countries , levels = c("Mundo", "Argentina", "Brasil", "Chile",
"Colombia", "Mexico", "Perú", "Estados Unidos"))
vaccinations <- vaccinations %>%
group_by(countries) %>%
mutate(month = 1:120,
vaccines = runif(120, min = 0, max = 5))
#Write text to add manually in each country
saved_text <- data.frame(
label_pais = c("10.10 per 100", "11.76 per 100", "12.58 per 100", "62.94 per 100",
"5.98 per 100", "8.84 per 100", "3.18 per 100", "55.96 per 100"),
countries = c("Mundo", "Argentina", "Brasil", "Chile",
"Colombia", "Mexico", "Perú", "Estados Unidos"))
saved_text$countries <- factor(saved_text$countries, levels = c("Mundo", "Argentina", "Brasil", "Chile",
"Colombia", "Mexico", "Perú", "Estados Unidos"))
ggplot()+
geom_line(
data = vaccinations,
aes(x = month, y = vaccines, colour = factor(countries)),
size = 2,
show.legend = FALSE
) +
geom_label(
data = saved_text,
mapping = aes(y = 4, x = 20, label = " "), # you have to adjust the blanks to your biggest label
color = "black", # desired color
label.size = 0.9
) +
facet_wrap( ~ countries, ncol = 1) +
geom_label(
data = saved_text,

In addition to all above answers, Make sure `nginx`, `httpd` or any other package you want to install is not in the `exclude` list of `yum.conf` file.
1. Open yum.conf file located at /etc/yum.conf
2. Check the exclude key and remove nginx* if it's there
3. Then try to install your package. in this case nginx: sudo yum install nginx

73,959,491 | 2 | null | 73,959,430 | 3 | null | The reason is simple. `let` is block scoped. It means that when you get out of the scope of your for loop, it does not exist. `var` scope is wider. What happens here is that the for loop increments `i` 5 times, then gets out of the loop with `i = 6` before the first setTimeout triggers (in less than 1 second) with a global scope. The `i` declared with `let` is from the function scope, while the `i` declared with var is from the outer scope
Difference between let and var:

73,959,506 | 2 | null | 73,959,430 | 1 | null | With `for` loop, each iteration has its own .
1. In the case of let as its block scope each iteration will have its own i variable and its value will be closure in the setTimeout, so each setTimeout will output the correct index
2. In the case of var as it's a functional scope, each iteration will override the previous one, and at the time of execution of the setTimeout the value of i will be 6 at the end of the iteration, will be logged in all setTimeout callbacks.

73,959,540 | 2 | null | 73,959,430 | 1 | null | The scope of `i` is different when using `let` and when using `var`
Here:
```
for(let i=0;i<=5;i++){ // i will not be available outside of the block below
setTimeout(
function clog(){
console.log(i)
},i*1000 );
// mentionning the variable i will cause a Reference error starting from here
```
Whereas with `var`, `i` gets hoisted, and defined without a value at the beginning of current the function's block, at the end of the loop `i` still exists, and has been mutated, so by the time the `setTimeout` callback is triggered, the loop will be already finished and `i` will have its final value, which is the first value not matching the looping condition (i.e. `6`).

73,959,548 | 2 | null | 73,959,430 | 1 | null | It is because of globally (var) or block scoped (let) value processing of javascript.
In var, variable i is globally changing and the loop finishes before settimeout function runs, so the i becomming 6 globally and console log writes yo it as 6.
In let, for every loop iteration there is an i variable belongs only that scope and settimeout function takes it, so the even if the loop finish it's job console log writes local varible i as 0,1,2,3,4,5.
I hope i tell myself correctly.

73,960,331 | 2 | null | 73,959,181 | 2 | null | You should use [Color.FromArgb()](https://learn.microsoft.com/en-us/dotnet/api/system.drawing.color.fromargb?view=net-6.0#system-drawing-color-fromargb(system-int32-system-int32-system-int32)) to create the new color. However, this method expects 3 `int` as input and not `double`, so you need to convert your doubles to integers.
## Simple type cast - (int)someDouble
This solution will simply remove any decimals from the double value (`1.9 => 1`):
```
double red1 = 123.45;
double green1 = 12.345;
double blue1 = 234.56;
Color newPixel = Color.FromArgb((int)red1, (int)green1, (int)blue1);
// R=123, G=12, B=234
```
## Math.Round(someDouble)
This solution will round the double value to the nearest integer (`1.5 => 2` and `1.49 => 1`):
```
int red1 = (int)Math.Round(123.45);
int green1 = (int)Math.Round(12.345);
int blue1 = (int)Math.Round(234.56);
Color newPixel = Color.FromArgb(red1, green1, blue1);
// R=123, G=12, B=235
```

73,960,721 | 2 | null | 73,960,558 | 0 | null | I'm not a PHP developer, but if I understand the question right, you want to color the whole table row background if it contains a "0" value to red, "1" value to green, etc.?
In this case you could create a function in php which could add a custom attribute to that specific row like this:
```
<table>
<tr my-attribute="0">
<td></td>
<td></td>
<td></td>
<td></td>
</tr>
<tr my-attribute="1">
<td></td>
<td></td>
<td></td>
<td></td>
</tr>
<tr my-attribute="2">
<td></td>
<td></td>
<td></td>
<td></td>
</tr>
<tr my-attribute="1">
<td></td>
<td></td>
<td></td>
<td></td>
</tr>
</table>
```
and for the css you could easily select this row like this:
```
tr[my-attribute="0"]{
background-color: red;
}
tr[my-attribute="1"]{
background-color: green;
}
tr[my-attribute="2"]{
background-color: yellow;
}

73,960,744 | 2 | null | 73,960,558 | 1 | null | Easiest would be to add a class with PHP in your while loop.
In your PHP code:
```
$colorclass = [0 => 'red', 1 => 'green', 2 => 'yellow'];
while (odbc_fetch_row($result)) // while there are rows
{
$classtext = '';
$x = odbc_result($result, "has_video");
if( in_array($x, $colorclass) )
{
$classtext = " class='".$colorclass[$x]."'";
}
print "<tr>\n";
print " <td>" . odbc_result($result, "project_ID") . "\n";
print " <td>" . odbc_result($result, "machine_project_ID") . "\n";
print " <td>" . odbc_result($result, "video_link") . "\n";
print " <td>" . odbc_result($result, "files_link") . "\n";
print " <td>" . odbc_result($result, "draw_link") . "\n";
print " <td>" . odbc_result($result, 'has_draw') . "\n";
print " <td".$classtext.">" . odbc_result($result, "has_video") . "\n";
print " <td>" . odbc_result($result, "has_files") . "\n";
print "</tr>\n";
}
```
In your CSS:
```
.red { background: red; }
.green { background: green; }
.yellow { background: yellow; }
```

You cant Parse a String with JSON.parse.
You have to use JSON.stringify() since this method converts a JavaScript value to a JSON string.

73,962,205 | 2 | null | 73,961,527 | 0 | null | Simply you can do if you don't want to change your data storing type in `localStorage`
```
..
initialState : {
user: JSON.parse(JSON.stringify(localStorage.getItem("user"))) || null,
// or user: localStorage.getItem('user') || null,
// both of them correct
isError: false,
isSuccess: false,
isLoading: false,
message: ''
},
..
```
`user: localStorage.getItem('user') || null`
---
`localStorage`:
```
// storing in obj.
const user = { token: <access_token> };
..
// stringifying for storage
localStorage.setItem('user',JSON.stringify(user));
..
// parsing for access
user: JSON.parse(localStorage.getItem("user"))

The `new` keyword with an array doesn't allow the test framework to differentiate (looking at the image you linked, it just says ).
```
[DataTestMethod]
[DataRow(0, new int[] { 1, 2, 3, 4 }, new int[] { 1, 3, 6, 10 })]
[DataRow(1, new int[] { 1, 1, 1, 1, 1 }, new int[] { 1, 2, 3, 4, 5 })]

already know, `Avg` is the average of these variables. Finally, `R'`, `G'`, `B'` are the new channel values calculated using the old values.

In order to show it one has to call [SQLDriverConnect](https://learn.microsoft.com/en-us/sql/odbc/reference/syntax/sqldriverconnect-function?view=sql-server-ver16) providing a windows handle, an empty InConnectionString and the SQL_DRIVER_COMPLETE for the DriverCompletion parameter.

# The git command git add -A ./** saved my life.
Until using this command nothing was working. I also renamed my current directory, went through and removed every single already present `.git` directory throughout, including the project root and all sub-directories. Added a very new and thorough .gitignore to the project root, and deleted the old remote repository that was previously started but wouldn't finish properly, all of which finally allowed me to start completely over with a brand new clean slate.
The only trade-off I made (which was more of a personal choice than a trade-off really, anywho...) was for each sub-directory that already contained a `.git` folder, I could have included those directories as git sub-modules instead of completely deleting those `.git` directories, which is really the more ideal or proper way of doing it. This was a personal decision, but most likely you will want to make sure to include them as sub-modules rather than deleting them, this way it will allow you to keep not only those repositories commit histories, but also continue to fetch future upstream changes and merge them back into your working directory, so just quick fyi and word of caution here. If you delete them as I did, you will lose all of that, which is probably not what most would want to do I think, so just fyi here!! - Hope that helps somebody!!
# Per the git man pages for git add
> `-A` short for `--all` "Updates the index not only where the working tree has a file matching `<pathspec>` but also where the index already has an entry. This adds, modifies, and removes index entries to match the working tree.If no `<pathspec>` is given when -A option is used, all files in the entire working tree are updated (old versions of Git used to limit the update to the current directory and its subdirectories)."
# Furthermore if you look in their glossary under "glob" you will find usage for a double asterisks like so:
> "A trailing `/**` matches everything inside. For example, `abc/**` matches all files inside directory `abc`, relative to the location of the `.gitignore` file, with ."

### Description of the algorithm
We start with a wallet , which is a set of coins
, , ..., , and
a pay amount : problem P(, ).
The solution to the problem is a selection of the coins in
the wallet, a subset of . A non-solution (that is
there are not enough funds to cover the amount) is
denoted by a void selection.
The solution is recursive.
#### Start solution
The default solution for P(, ) is (the selection is
the whole wallet) if the sum of coin values in the wallet is >=,
or ∅ (non-solution) otherwise.
#### Recursion
For each coin , we build a new wallet = ∖ {}, that is we extract that coin from the and solve the problem P(, ) i.e., we try to find if there's a better selection of coins from the smaller wallet.
The solution of P(, ) is the best one from the start solution and the partial wallet solutions.
Obviously, a selection is better if the sum of its coin values minus is smaller (but positive).
#### Bottom of recursion
We can directly solve a problem (that is without dividing it)
in three cases:
- - -
#### Memoization
[Memoization](https://en.wikipedia.org/wiki/Memoization) is essential
to reduce the run-time for this type of algorithms. It stores the
results of previous evaluations of the main function, in order
to avoid recomputing the same cases, very advantageous since
the amount of overlaps close to the bottom of recursion is huge.
I used memoization is a brute-force alternative to
a [dynamic programming](https://en.wikipedia.org/wiki/Dynamic_programming)
solution, that would make memoization unnecessary (or implicit).

Date/Time Value
Date =now() (Format the date to display however you like.)
Time =now() (Format the time to display however you like.)
```
Then follow with two different Select a Spreadsheet Row steps for the date and time, selecting the row name to get the values. Then when you go to send out a message, you can select the two Value item variables to put out the date and time, which will correspond with your spreadsheet time. If you need to alter the time at all, you can subtract or add the amount of hours you need to the =now() function.
Of course, you can just do one or the other or both. They'll go in as separate variables.

73,967,831 | 2 | null | 73,967,371 | 0 | null | Authentication of most API requests is straightforward - you attach an `Authorization` header with Oauth or JWT. This kind of auth is a simple fit for postman which has easy ways to pass Authorization headers.
One obvious flaw is that the authentication token is a secret that is sent along with the request. That means anyone that can access the request, knows the secret as well as you do.
AWS uses a different mechanism in which the secret is not attached to the payload. Instead, the secret is used to sign the request with HMAC. The secret isn't sent along with the payload, but anyone who already has the secret (AWS generated it in the first place) can verify that the payload was signed with the appropriate secret. In this scheme, intercepting a request payload does not divulge the secret necessary to authenticate novel requests.
[This blog post](https://blog.knoldus.com/how-to-generate-aws-signature-with-postman/) describes how postman can be made to authenticate API requests with [amazon's Signature v4 method](https://docs.aws.amazon.com/general/latest/gr/sigv4_signing.html). It looks possible.
My advice would be to stick to the AWS provided SDKs for one of your preferred languages. They offer high quality SDKs for python ("boto3" is a very common AWS go-to for crafting API requests), Ruby, Go, Java, JavaScript ... pretty much every language has one. The SDKs do a great job of representing the underlying AWS APIs, along with helping you manage error conditions, authentication, resolving endpoints for regions, pagination, etc.
