kandi X-RAY | kut Summary
This is a simple React-like web-view rendering library, developed when I learnt the source codes of React. Currently Kut supports two top-level methods, that's createElement and render, and also supports component-based development with class Component. Already cover some development requirements, and the home page was built based on Kut with acceptable performance. Kut improved the diff algorithm of React. Take my hat off to React, especially to the React Fiber. Kut is still under maintenance on my own, and will support the features like Context and Portal in the future. Free to pull request, and besides, welcome all your stars (lol).

...ANSWER
Answered 2020-Dec-16 at 17:12For any pointer or array p and index i, the expression p[i] is exactly equal to *(p + i).
If i == 0 then we have p[0] which is equal to *(p + 0) which in turn is equal to *(p) which is the same as *p.
And in your case *p is the same as s.

I'm looking for a way to display row number in my cross-tab.
I tried searching online for the answer on how to do it but I haven't found anything useful. So I'm turning to the good people on Stack Overflow. The reason that I want to do this, if it's even possible, is because many clients in the company I started working at asked to have a row number in the cross-tab. I am using Visual Studio 2013 and Crystal Reports. So is there any basic ( easy ) way to do this in Crystal Reports?
For example, I have a cross-tab that displays unit of measure and amounts.
But I would like my cross-tab to be like:
...ANSWER
Answered 2019-Mar-18 at 13:47In order to show Row Number in your CrossTab you will need to first put Row Number in the Stored Procedure that sends data to your report.
In order to understand it better i will first show you how my data looks before i add a Row number(Pic 1).

I am currently programming some descriptive analytics on a CSV file.
What I want to do; Create a bar chart of Location occurrence within the CSV file and plot to bar chart.

QUESTION
I have a custom camera app which have a centered rectangle view, as you can see below:
When I take a picture I want to ignore everything outside the rectangle. The view hasn't any connection with the Camera Preview or SurfaceView in my XML view, as follows:
...ANSWER
Answered 2018-Mar-26 at 02:58To control cropping, you must control the picture size and the rectangle size.
It is very important to a) choose the picture size with same aspect ratio as the preview, and b) make sure that the preview is not distorted on the screen. If you prepare your app for a wide range of devices, both tasks are not trivial. To achieve the latter, you need to control both preview size and the SurfaceView size. I have explained this in more detail elsewhere.
To keep it simple, I suggest to ignore the tablets that may have natural Landscape orientation. On phones, the captured image will be "rotated" 90° even if you set camera orientation to portrait (which only effects preview). Don't expect setRotation() to fix this for you: by the book, it is allowed to simply set the EXIF flag for the captured image.
You set the margins for viewTamanho in px. This may not scale well on variety of screens. I suggest setting the dimensions of this view programmatically, as certain percent of the preview surface. You can use support library to define this in XML, but I am afraid this will not give you enough control.
With all this at hand, let's say that we have preview of 1280×720, picture of 2560×1440, our screen is 1280×800, and the rectangle is in the middle, 616×400 pixels (which is more or less the size scaled from your screenshot).
The actual preview size on screen will be probably 1000x562, padded on the right and left with black margins of 79px. Then the following code will produce the expected captured picture:

QUESTION
I'm currently working on an application that makes use of the prestashop webservice. This means that the application i'm building is an extension of an existing prestashop application. The connection between both applications is through the prestashop webservice
Currently i'm trying to create a login script for thecustomers. The email and password are obtained from the database through the webservice and i'm able to filter the inputs with the existing row's. So when filling in login@test.com. The filter will only obtain the row with that email address.
The problem i'm having is with the password. Prestashop uses a _COOKIE_KEY_ together with anmd5() to encrypt passwords. See this link for more information: link
So i've been trying some different things for a while to check the inputted password with the customers password but i haven't found the solution yet.
Take a look at the code below:

QUESTION
My task is to save a file in the path specified by the end user (must be an absolute path). Am currently facing three different scenarios as in below:
- Path name is invalid (cannot be created) - for ex, path name provided by user : sfg rgdf gfggdgfudf
- Path name is invalid (but, it can be created) - for ex : C:\Parent\Child\GrandChildren (here C:\Parent exists whereas Child\GrandChildren does not.
- Path name is valid (i.e. directory exists) - for ex : C:\Parent\Test
For the first case, I need to save the file in a default location. For the second, I need to create directories and save the file. And for the last, I'll save in the specified path.
Below is my code snippet which is saving the file in default location for both first and second scenarios. Am having difficulty to distinguish between first and second. java.io.File.mkdirs works for the second case, but not for the first. Please ignore my poor code as am new to this programming language. Any inputs would be much appreciated.
