I'm using a WDM driver project in VS 2022. In case of the following code snippet:
extern "C" NTSTATUS NTAPI DriverEntry(PDRIVER_OBJECT DriverObject,
PUNICODE_STRING RegistryPath)
{
DbgPrint("v=%s", 123);
return STATUS_SUCCESS;
}
The `DbgPrint` has an incorrect `%s` specifier, which will cause that driver to crash.
The VS editor can see it and shows me an underlined [warning C6067][1]:
[![enter image description here][2]][2]
But when I compile it, that warning is not shown and the project compiles successfully, even though the settings for my project are set to "Level4 (/W4)".
Any idea how to enable that warning C6067 during compilation?

You also can use validator with some actions on raw data for field.
from pydantic import BaseModel, UUID4, SecretStr, EmailStr, constr, validator
class UserCreate(BaseModel):
email: EmailStr
password: SecretStr
first_name: str
last_name: str
@validator("email", "password", "first_name", "last_name", pre=True)
def strip_whitespaces(cls, v: str) -> str:
return v.strip()
|
Here’s an example of what it might look like:
```
add_filter( 'login_redirect', 'custom_login_redirect', 10, 3 );
function custom_login_redirect( $url, $request, $user ) {
if ( $user && is_object( $user ) && is_a( $user, 'WP_User' ) ) {
if ( $user->has_cap( 'administrator' ) ) {
$url = home_url();
}
}
return $url;
}
```
Note: You have to put this code into your functions.php

I have the following entities
```
@Builder
@Getter @Setter
@NoArgsConstructor
@AllArgsConstructor
@Entity(name = "Employee")
@Table(schema = "core", name = "employee")
public class EmployeeEntity {
@Id
@SequenceGenerator(schema = "core", name = Sequence.EMPLOYEE_ID_SEQ, sequenceName = Sequence.EMPLOYEE_ID_SEQ)
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = Sequence.EMPLOYEE_ID_SEQ)
@Column(name = "id", nullable = false, updatable = false)
private Integer id;
@Column(name = "person_id", nullable = false)
private Integer personId;
@Column(name = "user_account_id")
private Integer userAccountId;
@Column(name = "employee_type_id", nullable = false)
private Integer employeeTypeId;
@OneToOne(fetch = FetchType.EAGER)
@JoinColumn(name = "person_id", insertable = false, updatable = false)
private PersonEntity person;
@ManyToOne(fetch = FetchType.EAGER, targetEntity = EmployeeTypeEntity.class)
@JoinColumn(name = "employee_type_id", insertable = false, updatable = false)
private EmployeeTypeEntity employeeType;
}
```
and
```
@Builder
@Getter @Setter
@NoArgsConstructor
@AllArgsConstructor
@Entity(name = "EmployeeType")
@Table(schema = "type", name = "employee_type")
@Cacheable @Cache(usage = CacheConcurrencyStrategy.READ_ONLY)
public class EmployeeTypeEntity implements TypeTable {
@Id
@Column(name = "id", nullable = false, updatable = false)
private Integer id;
@Column(name = "name", length = 100, nullable = false)
private String name;
@Column(name = "abbreviation", length = 10)
private String abbreviation;
@Column(name = "description", length = 100)
private String description;
@Builder.Default
@Enumerated(EnumType.STRING)
@Column(name = "active", length = 1, nullable = false)
private Active active = Active.Y;
@OneToMany(fetch = FetchType.LAZY, mappedBy = "employeeType", targetEntity = EmployeeEntity.class)
private List<EmployeeEntity> employees;
}
```
Im using JPA Hibernate with panache in Quarkus and Im using the following method
```
@Override
public Pageable<EmployeeEntity> findAll(PageRequest request) {
var query = employeePanacheRepository.findAll(
Sort.by(request.getSortBy(), Direction.valueOf(request.getSortDirection()))
)
.page(Page.of(request.getPage(), request.getSize()));
return Pageable.<EmployeeEntity>builder()
.content(query.list())
.totalPages(query.pageCount())
.hasPrevious(query.hasPreviousPage())
.hasNext(query.hasNextPage())
.build();
}
```
The question here is why when ```query.list()``` is call Hibernate makes two Select
```
Hibernate:
select
ee1_0.id,
ee1_0.employee_type_id,
ee1_0.person_id,
ee1_0.user_account_id
from
core.employee ee1_0
order by
ee1_0.id
offset
? rows
fetch
first ? rows only
Hibernate:
select
ete1_0.id,
ete1_0.abbreviation,
ete1_0.active,
ete1_0.description,
ete1_0.name
from
type.employee_type ete1_0
where
ete1_0.id = any (?)
```
And things become more confusing for me when i have this other entity which is parent of EmployeeEntity and get all types table in one select
```
@Builder
@Getter @Setter
@NoArgsConstructor
@AllArgsConstructor
@Entity(name = "Person")
@Table(schema = "core", name = "person")
public class PersonEntity {
@Id
@SequenceGenerator(schema = "core", name = Sequence.PERSON_ID_SEQ, sequenceName = Sequence.PERSON_ID_SEQ)
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = Sequence.PERSON_ID_SEQ)
@Column(name = "id", nullable = false, updatable = false)
private Integer id;
@Column(name = "first_name", length = 100, nullable = false)
private String firstName;
@Column(name = "last_name", length = 100, nullable = false)
private String lastName;
@Column(name = "document_number", length = 50, nullable = false)
private String documentNumber;
@Column(name = "document_type_id", nullable = false)
private Integer documentTypeId;
@Column(name = "gender_type_id", nullable = false)
private Integer genderTypeId;
@Column(name = "birth_date", nullable = false)
private LocalDate birthDate;
@Column(name = "email", nullable = false)
private String email;
@Column(name = "mobile_number", nullable = false)
private String mobileNumber;
@UpdateTimestamp
@Column(name = "update_date", nullable = false)
private LocalDateTime updateDate;
@CreationTimestamp
@Column(name = "create_date", nullable = false)
private LocalDateTime createDate;
@Builder.Default
@Enumerated(EnumType.STRING)
@Column(name = "active", length = 1, nullable = false)
private Active active = Active.Y;
@ManyToOne(fetch = FetchType.EAGER)
@JoinColumn(name = "document_type_id", insertable = false, updatable = false)
private DocumentTypeEntity documentType;
@ManyToOne(fetch = FetchType.EAGER)
@JoinColumn(name = "gender_type_id", insertable = false, updatable = false)
private GenderTypeEntity genderType;
}
```
```
Hibernate:
select
pe1_0.id,
pe1_0.active,
pe1_0.birth_date,
pe1_0.create_date,
pe1_0.document_number,
dt1_0.id,
dt1_0.abbreviation,
dt1_0.active,

dt1_0.name,
pe1_0.document_type_id,
pe1_0.email,
pe1_0.first_name,

gt1_0.active,
gt1_0.description,
gt1_0.name,
pe1_0.gender_type_id,
pe1_0.last_name,
pe1_0.mobile_number,
pe1_0.update_date
from
core.person pe1_0
left join
type.document_type dt1_0
on dt1_0.id=pe1_0.document_type_id
left join
type.gender_type gt1_0
on gt1_0.id=pe1_0.gender_type_id
where

```
Someone can explain to me why this strange behavior with EmployeeEntity but no with PersonEntity

Is there any way to tell Notepad please do this...
FROM THIS

TO THIS
15.63387,46.42795,1,130,1,210
I would like to remove everything after the last ,
So that in the end it looks like
15.63387,46.42795,1,130,1,210
Thing is when I try it using Notepad++ with the command
FIND = [[:alpha:]] or [\u\l]
REPLACE = (leave it empty)
It removed all alphabetical charachters but it leaves , signs at the end, which I can remove with .{1}$ but for some reason some lines have empty spaces after...some one or more and this command does not work since notepad++ sees empty space as a character and therefore does not remove all the , signs at the end of each line. |
I'm going through [this][1] azure exercises and have a question regarding this statement:
> From the All resources view in the Azure portal, go to the Overview page of the production slot of the web app.
I have 2 deployment slots in my newly created test app services. Creating a `training-Staging` slot is the only configuration change I did for this app settings.:
Name | Status | App service plan | Traffic %
_________________________________________________________________________
training (Production) | Running | ASP-Training-a8b0 | 100
training-Staging | Running | ASP-Training-a8b0 | 0
However in the `All Resources` windows, I don't see a production slot (created by default) slot, only `training-Staging`:
Name | Type | Resource group | Location | Subscription
--------------------------------------------------------------------------------------------------------------------
Application Insights Smart Detection Action group Training Global ...
ASP-Training-a8b0 App Service plan Training East US ...
Training App Service Training East US ...
Training Application Insights Training East US ...
Staging (training/Staging) App Service (Slot) training East US ...
There is no link or button to go into configuration for production slot in `Deployment slots` configuration too (but such link exists for staging slot). Where can I find the production slot resource?

Since mod_dav_svn.so and mod_authz_svn.so were not present in SVN (TortoiseSVN), I downloaded the files from https://github.com/nono303/win-svn/tree/master/vc15/x64 and moved them to "C:\Apache24\modules".
I then added the following lines to the httpd.conf file in Apache24:
`# Subversion Configuration
LoadModule dav_svn_module modules/mod_dav_svn.so
LoadModule authz_svn_module modules/mod_authz_svn.so`
However, upon doing so, the service failed to start. Subsequently, the following error occurred:
`httpd.exe: Syntax error on line 188 of C:/Apache24/conf/httpd.conf: Cannot load modules/mod_dav_svn.so into server: \x8ew\x92\xe8\x82\xb3\x82\xea\x82\xbd\x83\x82\x83W\x83\x85\x81[\x83\x8b\x82\xaa\x8c\xa9\x82\xc2\x82\xa9\x82\xe8\x82\xdc\x82\xb9\x82\xf1\x81`

I'm using React Native Expo, and I want to open the default phone Contacts app.
**On Android, I used:**
await Linking.openURL("content://contacts/people/");
and that's worked.
On iOS that doesn't work.
**I tried:**
await Linking.openURL('contacts://');

You can scroll to a particular view in a `ScrollView` by using its id. This can either be done using a `ScrollViewReader` (as suggested in a comment) or by using a `.scrollPosition` modifier on the `ScrollView` (requires iOS 17).
Here is an example of how it can be done using `.scrollPosition`.
- The images used here are just system images (symbols). The symbol name is used as its id.
- The images in the scrolled view all have different heights. This makes it difficult for a `LazyVStack` to predict the scroll distance correctly, so a `VStack` is used instead. But if your images all have the same height then you could try using a `LazyVStack`.
- Set the target to scroll to in `.onAppear`.
- If you use `.center` as the anchor for scrolling then images in the middle of the list should be centered vertically in the display.
```swift
struct ContentView: View {
private let imageNames = ["hare", "tortoise", "dog", "cat", "lizard", "bird", "ant", "ladybug", "fossil.shell", "fish"]
private let threeColumnGrid: [GridItem] = [.init(), .init(), .init()]
var body: some View {
NavigationStack {
LazyVGrid(columns: threeColumnGrid, alignment: .center, spacing: 20) {
ForEach(imageNames, id: \.self) { imageName in
NavigationLink(destination: ScrollPostView(imageNames: imageNames, selectedName: imageName)){
Image(systemName: imageName)
.resizable()
.scaledToFit()
.padding()
.frame(maxHeight: 100)
.background(.yellow)
.clipShape(RoundedRectangle(cornerRadius: 15))
}
.overlay(
RoundedRectangle(cornerRadius: 15)
.stroke(Color.black, lineWidth: 2)
)
}
}
}
}
}
struct ScrollPostView: View {
let imageNames: [String]
let selectedName: String
@State private var scrollPosition: String?
var body: some View {
ScrollView {
VStack {
ForEach(imageNames, id: \.self) { imageName in
Image(systemName: imageName)
.resizable()
.scaledToFit()
.padding()
.background(selectedName == imageName ? .orange : .yellow)
.clipShape(RoundedRectangle(cornerRadius: 15))
}
}
.scrollTargetLayout()
}
.scrollPosition(id: $scrollPosition, anchor: .center)
.onAppear {
scrollPosition = selectedName
}
}
}

For me, using a .json file rather than a .js file for .eslintrc allowed `eslint .` to operate as it should in a module-based project.
Failed attempts (.eslintrc.js):
```js
export default {
// also tried: export {
// also tried: module.exports = {
"env": {
"browser": true,
"es2021": true
},
"extends": "eslint:recommended",
"overrides": [
{
"env": {
"node": true
},
"files": [
".eslintrc.{js,cjs}"
],
"parserOptions": {
"sourceType": "script"
}
}
],
"parserOptions": {
"ecmaVersion": "latest",
"sourceType": "module"
},
"rules": {
}
}
```
All of the above trigger:
```none
Error [ERR_REQUIRE_ESM]: require() of ES Module /path/to/.eslintrc.js from /home/me/.nvm/versions/node/v20.11.1/lib/node_modules/eslint/node_modules/@eslint/eslintrc/dist/eslintrc.cjs not supported.
```
This works (rename to .eslintrc.json, remove the `export` syntax and ensure valid JSON):
```json
{
"env": {
// ... same content above onward ...
}
```
package.json:
```json
{
"type": "module",
"devDependencies": {
"eslint": "^8.57.0"
}
}
```
Removing `"type": "module"` from the package.json and using CJS works, but my project requires `"type": "module"`, so this wasn't a good option.
There's probably a more direct solution, but [the accepted answer](https://stackoverflow.com/a/70458446/6243352) didn't seem to help in my case (or I'm doing something wrong). |
I have been trying to watch my tests WITH test coverage without much of a success. My best attempt sofar is to install packaeges `pip install pytest pytest-watch pytest-cov` and run on separate terminals or tabs these commands, below
Watch tests: `ptw --quiet --spool 200 --clear --nobeep --config pytest.ini --ext=.py --onfail="echo Tests failed, fix the issues" -v`
Coverage: coverage run --rcfile=.coveragerc -m pytest && coverage report --omit="tests/*,src/main.py,*/__init__.py,*/constants.py" --show-missing
An alternative to this approach is the shell script below. To run it, run command `chmod +x watch.sh && ./watch`
```
#!/bin/bash
clear
while true; do
coverage run --rcfile=.coveragerc -m pytest
coverage report --omit="tests/*,src/main.py,*/__init__.py,*/constants.py" --show-missing
sleep 5 # Adjust delay between test runs if needed
clear
done
```
It renders slower compared to command run `ptw`, but outputs exactly what I want. Would you please, provide maybe more effective alternatives than mine?
Thanks. :)

Perform an inner-[`merge`](https://pandas.pydata.org/docs/reference/api/pandas.DataFrame.merge.html):
```
index = df1.reset_index().merge(df2)['index'].tolist()
```
Or, if you have more columns but only want to consider a/b:
```
index = df1.reset_index().merge(df2, on=['a', 'b'])['index'].tolist()
```
If you can have duplicated combinations of a/b in either DataFrame:
```
index = df1.reset_index().merge(df2)['index'].unique().tolist()
```
Output: `[1, 3]` |
I think you just need to change how you call pagination, if your code sample is accurate: `page = RawQuerySetPaginator(queryset, 15)`
Pagination should have no issue with _most_ raw queries. Ordering and searching are, of course, an issue.
```py
class MyPagination(PageNumberPagination):
page_size = 1
qs = User.objects.raw("select email from user order by id desc")
paginator = MyPagination()
# page is a list of user objects here
page = paginator.paginate_queryset(qs, request=req)
# generate the list of dict objects for output
serialized_data = UserSerializer(page, many=True).data
# create a Response(), with the `count` and next/prev links
output = paginator.get_paginated_response(serialized_data)
```
Paginators are confusing, since they internally use a django paginator, and thus have a page, which has a paginator, which does the `.count`. How that does it I don't know, it's magic. `RawQuerySet` does not have a `count()` method but this still works somehow.
```
print(f"total records => {paginator.page.paginator.count}")
```
It may help you in testing, so here is the snippet I use to generate fake requests - you can't just use the output of the APIRequestFactory directly.
```
def make_request():
from rest_framework.test import APIRequestFactory
from rest_framework.request import Request
from rest_framework.parsers import JSONParser
req = APIRequestFactory().get("/", {"page": "1"})
return Request(req, parsers=[JSONParser()])

I aim to select full name of employees that either have no boss or their boss lives on a street that contains letter 'o' or letter 'u'. Then, I want to list them in descending order by full name.
The problem comes in the ordering, because by queries that I think are the same I get different answers.
When I introduce in MySQL Workbench the following command:
```
select concat(surnames,', ',name) as 'Full Name', street
from employee
where boss is null or (boss is not null and (street like'%u%' or steet like '%o%'))
order by concat(surnames,', ',name) desc;
```
By this command I get the answer I want, that is:
Full Name Street
Suárez García, Juan Juan Valdés 25
Sarasola Goñi, Vanesa Austria
Requena Santos, Pilar Alicante 3
Puertas Elorza, Marta Lope de Vega 3
Piedra Trujillo, Ramón Madre Vedruna 21
Narváez Alonso, Alba Vara de Rey 22
Gómez de la Sierra, Francisco Loscertales 9
Chávarri Díez, Lorea
Arrieta Alcorta, Kepa Urbieta 33
Álvarez González, Ana Graus 19
But when I change the ordering by another that looks the same to me:
```
select concat(surnames,', ',name) as 'Full Name', street
from employee
where boss is null or (boss is not null and (street like'%u%' or steet like '%o%'))
order by 'FullName' desc;
```
I get a wrong answer that looks like:
Full Name Street
Suárez García, Juan Juan Valdés 25
Puertas Elorza, Marta Lope de Vega 3
Chávarri Díez, Lorea
Narváez Alonso, Alba Vara de Rey 22
Gómez de la Sierra, Francisco Loscertales 9

Perhaps the easiest thing to do is to save the next group that would be generated. Then a future run can rebuild a new product instance that starts with that group:
def restart_product_at(start_group, *pools):
n = 0 # Position of the start_group
for element, pool in zip(start_group, pools):
n *= len(pool)
n += pool.index(element)
p = product(*pools) # New fresh iterator
next(islice(p, n, n), None) # Advance n steps ahead
return p
For example:
>>> p = restart_product_at(('c', 'e', 'm'), 'abcd', 'efg', 'hijklm')
>>> next(p)
('c', 'e', 'm')
>>> next(p)
('c', 'f', 'h')
>>> next(p)
('c', 'f', 'i') |
I'm attempting to implement the case change feature available in Microsoft Word with Shift + F3 into a TinyMCE React editor. The problem I'm running into is the last part where it should keep the same text selected/highlighted. The below works fine, as long as I haven't highlighted the last character of a node. If I have selected the end of a line, I get an error: `Uncaught DOMException: Index or size is negative or greater than the allowed amount`
So far I have the following:
```typescript
const handleCaseChange = (ed: Editor) => {
ed.on("keydown", (event: KeyboardEvent) => {
if (event.shiftKey && event.key === "F3") {
event.preventDefault();
const selection = ed.selection.getSel();
const selectedText = selection?.toString();
const startOffset = selection?.getRangeAt(0).startOffset;
const endOffset = selection?.getRangeAt(0).endOffset;
if (selectedText !== undefined && selectedText.length > 0) {
let transformedText;
if (selectedText === selectedText.toUpperCase()) {
transformedText = selectedText.toLowerCase();
} else if (selectedText === selectedText.toLowerCase()) {
transformedText = capitalizeEachWord(selectedText);
} else {
transformedText = selectedText.toUpperCase();
}
ed.selection.setContent(transformedText);
const range = ed.getDoc().createRange();
// This is what's currently erroring
range.setStart(selection.anchorNode, startOffset);
if (endOffset === selection?.anchorNode?.textContent?.length) {
range.setEndAfter(selection.anchorNode);
} else {
range.setEnd(selection.anchorNode, endOffset);
}
selection.removeAllRanges();
selection.addRange(range);
}
}
}
}
const capitalizeEachWord = (str: String) => str.replace(/\b\w/g, (char: string) => char.toUpperCase());
```
What else could I try in the `range.setStart` to get this to work correctly? |
I am using Svelte with [Ultralight][1], communication is handled with JavaScriptCore so Ultralight set / call functions on the global javascript object (which I believe is window). Now I want to call these functions in my svelte app, but I am using modules and so I can't set / use global functions.
So for now I am stuck to something like this :
`CppInterop.js` module :
import { notification } from "./lib/store";
// Expose store globally
window.store = {
notification
}
// Expose the C++ functions
export default {
test: () => window.Test()
}
`cpp.js` that I include directly in my html file with `<script src="/cpp.js"></script>` :
// From JS to C++
window.Test = Test;
// From C++ to JS
function notification(message, type)
{
window.store.notification.notify(message, type);
}
Interop doesn't seems to work then I try to access the functions via `window` so that's why I do `window.Test = Test`. What I would like is to call / define global function while still having access to modules (to call my own functions and stores), is that possible ?
Here is how the C++ set the interop functions :
JSValueRef JavascriptInterop::execute(const JSContextRef &ctx, const std::string &functionName, const std::vector<JSValueRef> &args)
{
JSObject global = JSGlobalObject();
JSValueRef exception = nullptr;
JSValueRef function = global[functionName.c_str()];
if (!JSValueIsObject(ctx, function))
{
throw std::runtime_error("Function not found");
}
JSObject functionObj = JSValueToObject(ctx, function, &exception);
if (exception)
{
throw std::runtime_error("Function not found");

For those using old LTS ***eclipse-temurin:17-jre-alpine*** or current LTS ***eclipse-temurin:21-jre-alpine*** the `wget` is included in default image, thus out of box **healthcheck** for docker compose would look like:
```yaml
healthcheck:
test: "wget -T5 -qO- http://localhost:8080/actuator/health | grep UP || exit 1"
interval: 15s
timeout: 5s
retries: 5
start_period: 20s
```
for kubernetes it would be
```yaml
spec:
containers:
...
livenessProbe:
httpGet:
path: /actuator/health
port: 8080
initialDelaySeconds: 20
periodSeconds: 15
failureThreshold: 5
timeoutSeconds: 5
```
The httpGet healthcheck probe will consider the application healthy when the status code is between 200 and 399.
In case the application is reporting a healthy state, /actuator/health API will respond with 200 and 503 when it’s down, thus will satisfy k8s healthcheck probe.

I have been trying to watch my tests WITH test coverage without much of a success. My best attempt sofar is to install packaeges `pip install pytest pytest-watch pytest-cov` and run on separate terminals or tabs these commands, below
1. Watch tests: `ptw --quiet --spool 200 --clear --nobeep --config pytest.ini --ext=.py --onfail="echo Tests failed, fix the issues" -v`
2. Coverage: `coverage run --rcfile=.coveragerc -m pytest && coverage report --omit="tests/*,src/main.py,*/__init__.py,*/constants.py" --show-missing`
An alternative to this approach is the shell script below. To run it, run command: `chmod +x watch.sh && ./watch`
```
#!/bin/bash
clear
while true; do
coverage run --rcfile=.coveragerc -m pytest
coverage report --omit="tests/*,src/main.py,*/__init__.py,*/constants.py" --show-missing
sleep 5 # Adjust delay between test runs if needed
clear
done
```
It renders slower compared to command run `ptw`, but outputs exactly what I want. Would you please, provide maybe more effective alternatives than mine?
Thanks. :)

You could try using the following formulas, this assumes there is no `Excel Constraints` as per the tags posted:
[![enter image description here][1]][1]
----------
=TEXT(MAX(--TEXTAFTER(B$2:B$7,"VUAM")*($A2=A$2:A$7)),"V\U\A\M\00000")
----------
Or, using the following:
=TEXT(MAX((--RIGHT(B$2:B$7,5)*($A2=A$2:A$7))),"V\U\A\M\00000")
----------
Or, you could use the following as well using `XLOOKUP()` & `SORTBY()`:
[![enter image description here][2]][2]
----------
=LET(
x, SORTBY(A2:B7,--RIGHT(B2:B7,5),-1),
y, TAKE(x,,1),
XLOOKUP(A2:A7, y, TAKE(x,,-1)))
----------
<sup> § Notes On **`Escape Characters`**: The use of `backslash` before & after the `V`, `U`, `A` & `M` is an **`escape character`**. Because the `V`, `U`, `A` & `M` on its own serves a different purpose, we are escaping it meaning hence asking Excel to **`literally form text`** with that character. </sup>
----------
Here is the **`Quick Fix`** to your **`existing formula`**, escape characters are not placed correctly, info on the same refer `§`
[![enter image description here][3]][3]
----------
=TEXT(MAX(IF($A$2:$A$100=A2, MID($B$2:$B$100, 5, 5)+0)),"V\U\A\M\00000")

I'm slowly learning .NET Core 8, and I'm using Identity with individual user accounts. I've recently learned how to add custom properties to the user account such as `FirstName` and `LastName`.
I would like to add a property called departments, however, each user may belong to several departments and so the `AspNetUsers` database table structure will not do. Ideally, I would have a separate table for departements (`Deptid, DeptName`) and another table for users in those departements (`userId, DeptId`) that can have multiple entries.
I know how to create such tables manually using SQL Server Management Studio and how to write the queries, but I am wondering if there is a way to add this with migrations and also have the usermanger return a list of departments for the user.
Can someone point me in the right direction. I'm not exactly sure what to even search for.
I am looking for information on this topic. |
I basically have to create a method that takes in a string array and a 2D array consisting of three double arrays and puts the first string with the first array, second string with the second array, etc.
public static void printData(String[] c, double[][] d)
{
String cname = "";
for(int i = 0; i < c.length; ++i)
{
cname = c[i];
for(int row = 0; row < d.length; ++row)
{
for(int col = 0; col < d[0].length; ++col)
{
System.out.print(d[row][col] + " ");
}
System.out.println();
}
}
Printed out the array a few times
//String word = "";
//for(int i = 0; i < c.length; ++i)
//{
//for(int row = 0; row < d.length; ++row)
//{
//System.out.println();
//for(int col = 0; col < d[0].length; ++col)
//{
//word = c[i];
//System.out.println(d[i][col]);
//}
//}
//}
I did get to the point where I was able to print the city names out with the entire 2D array under them.

It is indeed correct to type the property decorated with `ElementRef`, but it is just not enough: just add the generic type to `ElementRef`.
```typescript
@ViewChild("userSelector") userSelector: ElementRef<HTMLInputElement>;
...
onClickUser(user: User) {
this.userSelector.nativeElement.value = user.name;
...
}
```
The `ViewChild` decorator give you access to a typed `ElementRef` (in this case of `HTMLInputElement` => `ElementRef<HTMLInputElement>`), not an HTMLInputElement one!
If you want to observe a child component, you will directly get the component instance (so, no need to type the property to `ElementRef<My child component>>`). In that case you can just do the following:
```typescript
@ViewChild(MyComponent) myComponent?: MyComponent;
``` |
There is nothing you are missing. The assert can fail.
In particular, the compiler or CPU are permitted to do the store to `y` before the one to `x` in `write_x_then_y`, because the order of the two statements doesn't imply any additional happens-before constraint.
Then the other thread may do both loads in-between the two stores, so that the `if` condition will evaluate to `false`.
That you are not actually seeing this happen doesn't change that it is a permitted output and you have no guarantee that it won't behave differently after another compilation or even if you run the same binary often enough. It may happen only every one in a million or one in a billion runs or anything else. |
I had the same error when trying to run the application.
**------ start of error snippet -----------**
warning: default scripting plugin is disabled: The provided plugin org.jetbrains.kotlin.scripting.compiler.plugin.ScriptingCompilerConfigurationComponentRegistrar is not compatible with this version of compiler
error: unable to evaluate script, no scripting plugin loaded
**----- end of error snippet ------------**
The following steps worked for me
**(Android Studio Iguana | 2023.2.1 Patch 1)**
**1.** Open up "\.idea\workspace.xml" file under your project
**2.** Search the "workspace.xml" file for "RunManager". The <component> tag in the XML file looked like this:
<component name="RunManager" selected="Kotlin script (Beta).build.gradle.kts">
<configuration name="app" type="AndroidRunConfigurationType" factoryName="Android App">
**Changed the XML to as shown below:**
<component name="RunManager" selected="Android App.app">
<configuration name="app" type="AndroidRunConfigurationType" factoryName="Android App">
**Another option for Step 2** is
to delete the "selected" attribute and the IDE's auto update feature will add the correct "selected" attribute to the "component" tag.
**3.** Then perform this -> "clean project", "build project" and "run" the application and the error went away. App started running from the IDE.

In the C++ standard, `max_size()` is defined as
> *Returns*: `distance(begin(), end())` for the largest possible container.
\- [[container.reqmts] `max_size`](https://eel.is/c++draft/container.reqmts#lib:max_size,containers)
Initially, this looks good, and there is no *Preconditions* paragraph. However, `std::distance` returns `(last - first)` ([[iterator.operations] p5](https://eel.is/c++draft/iterator.operations#5)) and this is possibly undefined behavior for random access iterators (note the *Preconditions* in [[iterator.requirements] `b - a`](http://eel.is/c++draft/iterator.requirements#tab:randomaccessiterator-row-7)).
What is the standard actually trying to say here?
1. `max_size()` has no preconditions, so while it isn't *explicitly* stated, the largest possible container is required to have a `max_size()` so that `distance(begin(), end())` is well-defined.
2. `max_size()` is missing a *Preconditions* paragraph, and it's possible for `max_size()` to be undefined behavior if `end() - begin()` and by proxy, `std::distance(begin(), end())` is UB.
3. Something else.
The underlying question is:
> Does the absence of a *Preconditions* paragraph impose requirements on the implementation, or is it an editorial mistake? |

I read a little bit everywhere that the in operator have a time complexity of O(n), yet I used it in a code and idk why but it's acting as if it have the time complexity O(1)
So I was solving a problem on leetcode and ended up having this algorithm
```
class Solution(object):
def twoSum(self, nums, target):
"""
:type nums: List[int]
:type target: int
:rtype: List[int]
"""
i=0
n=len(nums)
for i in range (0, n-1):
if (target-nums[i]) in nums:
for j in range (i+1, n):
if nums[i]+nums[j]==target:
return[i, j]
```
and I ended up having runtime pretty similar to code like these that involve hashmaps:
```
class Solution(object):
def twoSum(self, nums, target):
"""
:type nums: List[int]
:type target: int
:rtype: List[int]
"""
hash_map = {}
for i in range(len(nums)):
complement = target - nums[i]
if complement in hash_map.keys():
return [i, hash_map[complement]]
hash_map[nums[i]] = i
```
It's weird because I read everywhere that the time complexity of the in operator for list is O(n), so I assumed this line
`if (target-nums[i]) in nums:`
would make my code equivalent to
```
class Solution(object):
def twoSum(self, nums, target):
self=list()
n=len(nums)
for i in range(n-1):
for j in range(i+1,n):
if nums[i]+nums[j]==target:
return [i,j]
```
yet it has the runtime of a code using hashmaps, and uses the memory of the code using the same list so O(1), anyone could explain that to me please? |

.NET Core 8, how can I add properties to user account that contains multiple values? |
struct MyStruct {
var a = 0

var myStruct = MyStruct()
runner(myStruct.foo) // Ok
runner(myStruct.increase) // Escaping autoclosure captures 'inout' parameter 'self'
How to make it works?
By the way, where is `autoclosure` here? And why is it escaping?
P.S.
I know I can just pass a "normal" closure: `runner { myStruct.increase() }` and it would work, but it's important for me to be able only to pass a name of a function to the `runner`.
P.S.
Actually there are a lot of similar questions on SOF already. I've read them all, and as far as I understand, it's impossible to do. Which is the answer that doesn't suit me |

I have a frame layout that wants to fill 50% of the screen reso, then a tablayout below and a viewpager with 3 different fragment layouts based on the tabs. The tabs/viewpager works and shows the layouts when i remove scrollview, otherwise using this code it just show a blank viewpager. Can someone help me to enable a scrolling function for the viewpager without the viewpager from disappearing/not showing?
The viewpager adapters are functional but adding a scrollview to scroll the fragment layouts of the viewpager makes the whole viewpager disappear.

Unfortunately, Flutter doesn't have `controller.jumpToIndex(index);`
you can achieve this by adding a third-party library which is called [**scrollable_positioned_list**][1].
It is exactly like ListView but you can use `controller.jumpToIndex(index);`
For Example:
Init controller:
final ItemScrollController itemScrollController = ItemScrollController();
Add widget:
ScrollablePositionedList.builder(
itemCount: 500,
itemBuilder: (context, index) => Text('Item $index'),
itemScrollController: itemScrollController,
scrollOffsetController: scrollOffsetController,
itemPositionsListener: itemPositionsListener,
scrollOffsetListener: scrollOffsetListener,
);
Call `scrollTo` method:
itemScrollController.scrollTo(
index: 150,
duration: Duration(seconds: 2),
curve: Curves.easeInOutCubic);
**Happy Coding :)**

Change this line:
```
output = p4.run("print", "-o", temp_file, f"{file_path}@{changelist_number}")
```
to:
```
output = p4.run("print", "-o", temp_file, f"{file_path}@={changelist_number}")
```
and make sure that your trigger is running as `change-content` rather than `change-submit`.
The important detail is the `@=` revision specifier, which can be used to refer to unsubmitted files on the server (i.e. a midflight submit in a `change-content` trigger, or a shelved change -- note that at the time `change-submit` fires, the files are not yet on the server).
Normally a revision specifier can only ever refer to *submitted* revisions, but `@=` is a special exception when it refers to a pending change that contains either mid-submit or shelved files. |
### Strategy for Answering
Exactly what the `conda init` command does and its consequences are shell-specific. Instead of trying to cover all cases, let's walk through a case, noting along the way that one can replicate this analysis by substituting their shell of interest.
---
# Case Study: `conda init zsh`
Let's look at `zsh` as the shell. This is a common shell (default for macOS 10.15+) and very close to bash. Plus, I don't already have it configured.
## Probing the Command: Dry Run
Many Conda commands include some form of dry run functionality via a `--dry-run, -d` flag, which - combined with verbosity flags - enables seeing what this would do without doing them. For the `init` command, dry run alone will only tell us what files it *would* modify:
``` lang-bash
$ conda init -d zsh
no change /Users/mfansler/miniconda3/condabin/conda
no change /Users/mfansler/miniconda3/bin/conda
no change /Users/mfansler/miniconda3/bin/conda-env
no change /Users/mfansler/miniconda3/bin/activate
no change /Users/mfansler/miniconda3/bin/deactivate
no change /Users/mfansler/miniconda3/etc/profile.d/conda.sh
no change /Users/mfansler/miniconda3/etc/fish/conf.d/conda.fish
no change /Users/mfansler/miniconda3/shell/condabin/Conda.psm1
no change /Users/mfansler/miniconda3/shell/condabin/conda-hook.ps1
no change /Users/mfansler/miniconda3/lib/python3.7/site-packages/xontrib/conda.xsh
no change /Users/mfansler/miniconda3/etc/profile.d/conda.csh
modified /Users/mfansler/.zshrc
==> For changes to take effect, close and re-open your current shell. <==
```
Here we can see that it plans to target the user-level resources file for zsh, `/Users/mfansler/.zshrc`, but it doesn't tell us how it will modified it. Also, OMG! the UX here is awful, because it in no way reflects the fact that I used the `-d` flag. But don't worry: as long as the `-d` flag is there it won't actually change things.
### Patch Preview
To see what exactly it will do, add a single verbosity flag (`-v`) to the command. This will give everything from the previous output, but will now shows us the diff it will use to patch (update) the `.zshrc` file.
``` lang-bash
$ conda init -dv zsh
/Users/mfansler/.zshrc
---
+++
@@ -0,0 +1,16 @@
+
+# >>> conda initialize >>>
+# !! Contents within this block are managed by 'conda init' !!
+__conda_setup="$('/Users/mfansler/miniconda3/bin/conda' 'shell.zsh' 'hook' 2> /dev/null)"
+if [ $? -eq 0 ]; then
+ eval "$__conda_setup"
+else
+ if [ -f "/Users/mfansler/miniconda3/etc/profile.d/conda.sh" ]; then
+ . "/Users/mfansler/miniconda3/etc/profile.d/conda.sh"
+ else
+ export PATH="/Users/mfansler/miniconda3/bin:$PATH"
+ fi
+fi
+unset __conda_setup
+# <<< conda initialize <<<
+
# ...the rest is exactly as above
```
That is, the plan of action is to add these 16 lines to the `.zshrc` file. In this case, I don't have an existing `.zshrc` file, so it plans to add it at line 1. If the file had already existed, it would append these lines.
---
## Interpreting the Shell Code
Let's overview this code, before focusing on the details. Essentially, this is a redundant sequence of attempts to set up some shell functionality. They are ordered from most to least functional.
### What Conda Hopes To Do
The code
```
__conda_setup="$('/Users/mfansler/miniconda3/bin/conda' 'shell.zsh' 'hook' 2> /dev/null)"
if [ $? -eq 0 ]; then
eval "$__conda_setup"
```
gets something from `conda` itself, storing the result to a string, and then evaluates that string if the command had a clean exit (`$? -eq 0`). The neat engineering here is that the subprocess (technically `python -m conda`) passes back a result that can be run within this current process (`zsh`), allowing it to define shell functions.
I'll dig deeper into what is going on here in a second.
### Fallback 1: Hardcoded Shell Functions
If that strange internal command fails, the devs included a hardcoded version of some essential shell functions (specifically `conda activate`). This is in:
miniconda3/etc/profile.d/conda.sh
and they simply check the file exists and source it. Let's hit that last option, then we'll swing back to look at the functionality.
### Fallback 2: The Last Resort
The absolute last resort is to literally violate the standing recommendation since Conda v4.4, which is to simply put the **base** environment's `bin` directory on `PATH`. In this case, there is no `conda activate` functionality; this only ensures that Conda is on your PATH.
---
## Details: Shell Functionality
Coming back to the intended case, we can inspect exactly what it would evaluate by simply getting that string result:
``` lang-bash
$ conda shell.zsh hook
__add_sys_prefix_to_path() {
# In dev-mode CONDA_EXE is python.exe and on Windows
# it is in a different relative location to condabin.
if [ -n "${_CE_CONDA}" ] && [ -n "${WINDIR+x}" ]; then
SYSP=$(\dirname "${CONDA_EXE}")
else
SYSP=$(\dirname "${CONDA_EXE}")
SYSP=$(\dirname "${SYSP}")
fi
if [ -n "${WINDIR+x}" ]; then
PATH="${SYSP}/bin:${PATH}"
PATH="${SYSP}/Scripts:${PATH}"
PATH="${SYSP}/Library/bin:${PATH}"
PATH="${SYSP}/Library/usr/bin:${PATH}"
PATH="${SYSP}/Library/mingw-w64/bin:${PATH}"
PATH="${SYSP}:${PATH}"
else
PATH="${SYSP}/bin:${PATH}"
fi
\export PATH
}
__conda_exe() (
__add_sys_prefix_to_path
"$CONDA_EXE" $_CE_M $_CE_CONDA "$@"
)
__conda_hashr() {
if [ -n "${ZSH_VERSION:+x}" ]; then
\rehash
elif [ -n "${POSH_VERSION:+x}" ]; then
: # pass
else
\hash -r
fi
}
__conda_activate() {
if [ -n "${CONDA_PS1_BACKUP:+x}" ]; then
# Handle transition from shell activated with conda <= 4.3 to a subsequent activation
# after conda updated to >= 4.4. See issue #6173.
PS1="$CONDA_PS1_BACKUP"
\unset CONDA_PS1_BACKUP
fi
\local ask_conda
ask_conda="$(PS1="${PS1:-}" __conda_exe shell.posix "$@")" || \return
\eval "$ask_conda"
__conda_hashr
}
__conda_reactivate() {
\local ask_conda
ask_conda="$(PS1="${PS1:-}" __conda_exe shell.posix reactivate)" || \return
\eval "$ask_conda"
__conda_hashr
}
conda() {
\local cmd="${1-__missing__}"
case "$cmd" in
activate|deactivate)
__conda_activate "$@"
;;
install|update|upgrade|remove|uninstall)
__conda_exe "$@" || \return
__conda_reactivate
;;
*)
__conda_exe "$@"
;;
esac
}
if [ -z "${CONDA_SHLVL+x}" ]; then
\export CONDA_SHLVL=0
# In dev-mode CONDA_EXE is python.exe and on Windows
# it is in a different relative location to condabin.
if [ -n "${_CE_CONDA:+x}" ] && [ -n "${WINDIR+x}" ]; then
PATH="$(\dirname "$CONDA_EXE")/condabin${PATH:+":${PATH}"}"
else
PATH="$(\dirname "$(\dirname "$CONDA_EXE")")/condabin${PATH:+":${PATH}"}"
fi
\export PATH
# We're not allowing PS1 to be unbound. It must at least be set.
# However, we're not exporting it, which can cause problems when starting a second shell
# via a first shell (i.e. starting zsh from bash).
if [ -z "${PS1+x}" ]; then
PS1=
fi
fi
conda activate base
```
I'm not going to walk through all this, but the main part is that instead of directly putting `bin` on PATH, it defines a shell function called `conda` and this serves as a wrapper for the `condabin/conda` entrypoint. This also defines a new functionality `conda activate`, which uses a shell function, `__conda_activate()`, behind the scenes. At the final step, it then activates the **base** environment.
**Why do it this way?**
This is engineered like this in order to be responsive to the configuration settings. Configuration options like `auto_activate_base` and `change_ps1` affect how Conda manipulates the shell, and so that changes what functionality Conda includes in its shell functions.
---
# Does Conda "Pollute the Environment"?
Not really. The main behavioral things like auto-activation and prompt modification can be disabled through configuration settings, so that `conda init` ultimately just adds the `conda activate` function to the shell, enabling clean switching between environments without ever having to manually manipulate PATH.

I see two possible options here. First is "more formally correct", but way too permissive, approach relying on `partial` hint:
```python
from __future__ import annotations
from functools import partial
from typing import Callable, TypeVar, ParamSpec, Any, Optional, Protocol, overload, Concatenate
R = TypeVar("R")
P = ParamSpec("P")
class YourCallable(Protocol[P, R]):
@overload
def __call__(self, value: float, *args: P.args, **kwargs: P.kwargs) -> R: ...
@overload
def __call__(self, value: None = None, *args: P.args, **kwargs: P.kwargs) -> partial[R]: ...
def lazy(func: Callable[Concatenate[float, P], R]) -> YourCallable[P, R]:
def wrapper(value: float | None = None, **kwargs: P.kwargs) -> R | partial[R]:
if value is not None:
return func(value, **kwargs)
else:
return partial(func, **kwargs)
return wrapper # type: ignore[return-value]
@lazy
def test_multiply(value: float, *, multiplier: float) -> float:
return value * multiplier
@lazy
def test_format(value: float, *, fmt: str) -> str:
return fmt % value
print('test_multiply 5*2:', test_multiply(value=5, multiplier=2))
print('test_format 7.777 as .2f:', test_format(value=7.777, fmt='%.2f'))
func_mult_11 = test_multiply(multiplier=11) # returns a partial function
print('Type of func_mult_11:', type(func_mult_11))
print('func_mult_11 5*11:', func_mult_11(value=5))
func_mult_11(value=5, multiplier=5) # OK
func_mult_11(value='a') # False negative: we want this to fail
```
Last two calls show hat is good and bad about this approach. `partial` accepts any input arguments, so is not sufficiently safe. If you want to override the arguments provided to lazy callable initially, this is probably the best solution.
Note that I slightly changed signatures of the input callables: without that you will not be able to use `Concatenate`. Note also that `KwArg`, `DefaultNamedArg` and company are all deprecated in favour of protocols. You cannot use paramspec with kwargs only, args must also be present. If you trust your type checker, it is fine to use kwarg-only callables, all unnamed calls will be rejected at the type checking phase.
However, I have another alternative to share if you do not want to override default args passed to the initial callable, which is fully safe, but emits false positives if you try to.
```python
from __future__ import annotations
from functools import partial
from typing import Callable, TypeVar, ParamSpec, Any, Optional, Protocol, overload, Concatenate
_R_co = TypeVar("_R_co", covariant=True)
R = TypeVar("R")
P = ParamSpec("P")
class ValueOnlyCallable(Protocol[_R_co]):
def __call__(self, value: float) -> _R_co: ...
class YourCallableTooStrict(Protocol[P, _R_co]):
@overload
def __call__(self, value: float, *args: P.args, **kwargs: P.kwargs) -> _R_co: ...
@overload
def __call__(self, value: None = None, *args: P.args, **kwargs: P.kwargs) -> ValueOnlyCallable[_R_co]: ...
def lazy_strict(func: Callable[Concatenate[float, P], R]) -> YourCallableTooStrict[P, R]:
def wrapper(value: float | None = None, **kwargs: P.kwargs) -> R | partial[R]:
if value is not None:
return func(value, **kwargs)
else:
return partial(func, **kwargs)
return wrapper # type: ignore[return-value]
@lazy_strict
def test_multiply_strict(value: float, *, multiplier: float) -> float:
return value * multiplier
@lazy_strict
def test_format_strict(value: float, *, fmt: str) -> str:
return fmt % value
print('test_multiply 5*2:', test_multiply_strict(value=5, multiplier=2))
print('test_format 7.777 as .2f:', test_format_strict(value=7.777, fmt='%.2f'))
func_mult_11_strict = test_multiply_strict(multiplier=11) # returns a partial function
print('Type of func_mult_11:', type(func_mult_11_strict))
print('func_mult_11 5*11:', func_mult_11_strict(value=5))
func_mult_11_strict(value=5, multiplier=5) # False positive: OK at runtime, but not allowed by mypy. E: Unexpected keyword argument "multiplier" for "__call__" of "ValueOnlyCallable" [call-arg]
func_mult_11_strict(value='a') # Expected. E: Argument "value" to "__call__" of "ValueOnlyCallable" has incompatible type "str"; expected "float" [arg-type]
```
You can also mark `value` kw-only in `ValueOnlyCallable` definition if you'd like, I just don't think it is reasonable for a function with only one argument.
You can compare both approaches in [playground](https://mypy-play.net/?mypy=master&python=3.11&flags=strict&gist=52aefd1e46c49e73206e0efbca17b193). |
I am learning Spark, so as a task we had to create a wheel locally and later install it in Databricks (I am using Azure Databricks), and test it by running it from a Databrick Notebook. This program involves reading a CSV file (timezones.csv) included inside the wheel file. The file *is* inside the wheel (I checked it) and also the wheel works properly when I install it and run it from a local PC Jupyter Notebook. However, when I install it in Databricks Notebook it gives this error, as you can see below in the snapshot:

Has anyone experienced this problem before? Is there any solution?
I tried installing the file both with pip and from Library, and I got the same error, also rebooted the cluster several times.
Thanks in advance for your help.
I am using Python 3.11, Pyspark 3.5 and Java 8 and created the wheel locally from PyCharm. If you need more details to answer, just ask and I'll provide them.
I explained all the details above. I was expecting to be able to use the wheel I created locally from a Databricks Notebook.
Sorry about my English is not my native tongue and I am a bit rusty.

Does anyone know how to fix this?

Is there any way to tell Notepad please do this...
FROM THIS
15.63387,46.42795,1,130,1,210,Sele pri Polskavi
TO THIS
15.63387,46.42795,1,130,1,210
I would like to remove everything after the last ,
So that in the end it looks like
15.63387,46.42795,1,130,1,210
Thing is when I try it using Notepad++ with the command
FIND = [[:alpha:]] or [\u\l]
REPLACE = (leave it empty)
It removed all alphabetical charachters but it leaves , signs at the end, which I can remove with .{1}$ but for some reason some lines have empty spaces after , sign.
Some lines have one or more and this command .{1}$ does not work since notepad++ sees empty space as a character and therefore does not remove all the , signs at the end of each line. |
