I’d be grateful for suggestions as to how to remap letters in strings in a map-specified way.

Suppose, for instance, I want to change all As to Bs, all Bs to Ds, and all Ds to Fs. If I do it like this, it doesn’t do what I want since it applies the transformations successively:

I have a field in my table that contains a string that can follow any of 3 formats:

1. null
2. "[string]"
3. "Following fields matched: {string=string, string=string, string=string..}"

For 1 I need output : null For 2 I need output : For 3 I need to split each pair into its each row with columns [key] & [value]

Now, I have solved this challenge, I just think that I have done it in the most eloquent or efficient manner.

Would be grateful if anyone could point me to a better solution ? Thanks

I have a navigation menu that I made for a test application, there are some tabs that I want to hide if I am not logged into the application. After logging in, these tabs should appear. The problem is that after logging in, I go to the desired page and I don't see all the navigation menu icons. For them to appear, I need to click on one of the available icons (only 2 icons are available for authorization) and only then the navigation menu will be updated and everything will be as it should be. All 6 icons will be visible! Can someone help me with this? Here I described the problem with the code that I am using. I would be grateful for any help.

I'm trying to validate some JSON files on VB.net. However, Whenever I run my code it gets stuck on

Dim Schema As JsonSchema = JsonSchema.Parse(SchemaString)

The Error Says

An unhandled exception of type 'Newtonsoft.Json.JsonException' occurred in Newtonsoft.Json.dll.

There is also a warning that says that JSON validation moved to its own package. So, I'm pretty sure I'm just importing the wrong packages, but I'm not sure.

I would be grateful if anyone could point me in the correct direction,

Thank you.

Here is my VB.net code

I've got this shell script which takes a set of INSERT statements and puts a 'BEGIN TRANSACTION' on th start and a 'COMMIT' on the end. There are lot of INSERT statements and so this makes the insertion a lot faster.

The script I've used successfully looks like this

I am trying to understand the constructor of a std::thread but fail to understand how parameter types are represented/handled. Judging from cppreference, a simplified constructor could be sketched as follows:

Here when I type inside text fields Keyboard covers the Login button. So I need to scroll down to the Login button when typing. I tried wrapping LayoutBuilder with SingleChildScrollView and tried using Positioned widget inside Stack but nothing solved my issue. And I set physics to AlwaysScrollableScrollPhysics() inside SingleChildScrollView but it also didn't solve the problem. I can't figure out what I've done wrong. I would be grateful if anyone can help me with this issue

Here's my code

I am writing a program which constantly checks if certain IP adresses are connected to the network. If they are, nothing happens. If they are not connected for a certain time, an action is triggered. My script works as intended as far as I can tell, however when I try to exit it using ctrl+c it simply doesnt stop. I guess it has something to do with the threading that I am using, but I cant figure out what exactly it is. This is my code so far:

I recently found out there is a very handy method in three-box for placing three.js objects on the map which is "projectToworld".

While trying to place my three.js objects using the method, I realized that the Vector3 the method returns are really huge and not on the map.

According to the documentation of threebox, it says

projectToWorld

tb.projectToWorld(lnglat) : THREE.Vector3

Calculate the corresponding THREE.Vector3 for a given lnglat. It's inverse method is tb.unprojectFromWorld.

So I decided to use this method to locate my animated object in three js canvas. But what the methods returns are really huge.

So as I expected, these values don't place the three objects on the map and all the objects disappeared because they presumably are placed at very distant locations.

How do I fix this issue?

I made a minimal code to demonstrate this issue as below.
