I have a Blazor ServerSide application, where I am adding authentication. I have 2 ways to authenticate, depending on development or production. In production,we use OpenID. In dev, the user is always authenticated, with the same claims that an OpenID gives. My end goal is to authenticate via OpenID, and post authentication, check if the user is in the database. If they are not,...

Issue with VS Code not pick up auto-imports for the Button.d.ts. VS Code manages to detect the .d.ts file and auto-import it if I rename it to index.d.ts.

I would like to bring to your attention my straightforward code. However, I am encountering an issue where the code does not return the data from the first column after applying the group by function. Could you please advise me on how I can extract the data from the first column or the primary grouping column to create a list or a new data...

Is it in any way possible to provide partial examples, such as in the following case, where b is missing from the example decorator? @given(a=st.integers(), b=st.integers()) @example(a=0) def test_example(a, b): ...

I have a simple yet perplexing problem. I have a reactive form and I want to set validation programatically. this.boatForm.get('boatType').setValidators(Validators.required); this.boatForm.updateValueAndValidity(); this.boatForm.get('boatType').updateValueAndValidity(); this.#logger.debug( '/n', 'value:', this.boatForm.get('boatType').value, '/n', 'valid:', this.boatForm.get('boatType').valid ) The value of the boatType control is null. Therefore I expect the log to show: value: valid: false And... it does. But I have multiple controls on that form so instead of applying updateValueAndValidity()...

Currently trying to fix the lighting for when i rotate my model the normals are rotatet with the model and the lighting hits the surface that is facing the light. I used a method where i inverse and tranpose a NormalMatrix, which is a matrix 3x3 the cameraMatrix multiplied by model, but when starting the application and I rotate my camera the lighting adjusts...

I'm trying to make a temporary program that will get the classes from a website and then append any new classes not already found in a list "all_classes" TO all_classes*. for a list of length ~150k words. Also, I do have some code, but it just: sucks seems to be riddled with annoying bugs and inconsistancies is so slow that it takes a day...

I have looked at many explanations about what git diff between 2 commits does, and I am still completely baffled about the output I am getting. I believe what I am seeing is "combined format", said to be the "default" format, but if so I don't know what other formats are available. Example: >git diff af738ab0..bbbec26d > gitdiff_2025-04-09B.diff Typically I get this kind of...

I have this entity: public class Customer { public int Id { get; set; } public string Email { get; set; } public IEnumerable<Order> Orders{ get; set; } = []; internal byte[] OrdersArray { get; set; } public User() { } } And the mapping: internal class CustomerMap : EntityMappingConfiguration<Customer> { public override void Map(EntityTypeBuilder<Customer> b) { b.ToTable("Customers").HasKey(t => t.Id); b.Property(t => t.Id).HasColumnName("Id").ValueGeneratedOnAdd(); b.Property(t...

I've already failed to my exam for this task :( I can't iterate through all nested objects to get only '.js' files. The property check for the function is not working in all of the cases and can not pass: test 3. Just can not jump in a new Folder(["7.txt", "9.js"])] to get "9.js" and my expectedResult: ["1.js", "2.js", "4.js", "6.js", "7.js", "8.js" ]...

I've have a load of function overloads, mainly consisting of two signatures: void func(const my_type1&); void func(const my_type2&, hash_t); and a function that tries to call func based on function existance: template <typename T> void func_imp(const T& t, hash_t hash){ if constexpr (has_func_with_2nd_param_v<T>){ func(t, hash); }else{ func(t); } } but I'm running into conversion issues which end up calling the 'wrong' overload: #include <type_traits>...

First here's a block of code that reproduce the issue: import SwiftUI struct CustomAnimation: ViewModifier { @State private var isAnimated: Bool = false func body(content: Content) -> some View { content .phaseAnimator([true, false], trigger: self.isAnimated) { view, phase in view .scaleEffect(phase ? 1 : 1.2) } .onTapGesture { self.isAnimated.toggle() } } } #Preview { @Previewable @State var isPresented: Bool = true VStack { Button...

This is my running code: function carousel() { var x = document.getElementsByClassName("mySlides"); for (let i = 0; i < x.length; i++) { x[i].style.display = "none"; } myIndex++; if (myIndex > x.length) { myIndex = 1 } x[myIndex - 1].style.display = "block"; setTimeout(carousel, 2000); // Change image every 2 seconds } .container { padding: 0rem; } .slider-wrapper { position: relative; max-width: auto; margin: 0 auto;...

I have a templated class that contains a tuple. template <class... SomeTypes> class Foo { ... }; How can I apply a constraint on the types contained in the SomeTypes parameter pack? For instance, if I wanted to ensure that all of the types fit the std::movable concept? What if SomeTypes was also templates? template < template<typename> class... SomeTypes> class Bar { ... };...

I'm getting a suggestion to use a collection expression which leads to a compiler error: public async IAsyncEnumerable<object> WrapObjectAsync(IEnumerable<object> items, [EnumeratorCancellation] CancellationToken token) { // FOCUS ON THIS --> Queue<(object, SomeEnum)> queue = new Queue<(object, SomeEnum)>(items.Select(item => (item, SomeEnum.SomeValue))); // Suggestion from VS : Queue<(object, SomeEnum)> queue = [.. items.Select(item => (item, SomeEnum.SomeValue))]; /* Compiler Error : * 'Queue<(object, SomeEnum)>' does not contain a...

I'm writing a chat app using django channels, redis and daphne. When I try to submit the message and tap on the button I have GET query, but I've written js in my html file and it has to prevent standart behaviour of this form. I don't know why doesn't it establish the connection and just send GET query, what's wrong here? I've checked...

I'm learning about encryption in Oracle 21 and trying to use Oracle Wallet to store the key, but I'm facing some issues. Here are the steps I took to create the wallet: Open CMD, create a new directory for the wallet. mkdir C:\oracle\wallet (my oracle is installed in a different directory, not the oracle right here.) Create the wallet C:\app\ADMIN\product\21c\dbhomeXE\bin\mkstore -wrl C:\oracle\wallet -create Add...

I have a Vite+React app using Vite React template. The app is hosted in a Azure WebApp service and the very 1st deployment after the WebApp is created in Azure, goes fine without any issues. Every 2nd deployment however, I end up with the error, as below. 2025-04-09T08:01:10.8417387Z dist/assets/react-router-BjM9WsHm.js 73.52 kB │ gzip: 25.26 kB 2025-04-09T08:01:10.8417677Z dist/assets/react-dom-CNorE7jC.js 172.91 kB │ gzip: 54.59 kB 2025-04-09T08:01:10.8511884Z...

I'm wondering if it is possible to make IntelliSense ignore any EditorBrowsableAttribute in Visual Studio, so that it shows all methods of a class that would usually be visible if the EditorBrowsableState wasn't there. I've had multiple occasions where I thought a feature wouldn't exist for a specific class, just to later find out it was actually just the method being marked as Advanced...

Say I have several attributes and the data entry across a row must balance. Is this possible? (I've seen data validation for an attribute must be greater/less than or equal to another or when one is 0 then another must have a value). | ColA | ColB | ColC | ColD | | | | | | | Val1 | Val2 | Val3 |...

We are following this documentation on how to handle errors thrown by docxtemplater. We are using TypeScript and the example seems only to work with JS. We wouldn't want to use any as a type unless necessary. How would you do this in TypeScript using correct types? function replaceErrors(key, value) { if (value instanceof Error) { return Object.getOwnPropertyNames(value).reduce( function (error, key) { error[key] =...
