kandi X-RAY | poi Summary
In "point-free" or "tacit" programming, functions do not identify the arguments (or "points") on which they operate. See [Wikipedia article] Poi is an implementation of a small subset of [Path Semantics] In order to explain how Poi works, one needs to explain a bit about Path Semantics. [Path Semantics] is an extremely expressive language for mathematical programming, which has a "path-space" in addition to normal computation. If normal programming is 2D, then Path Semantics is 3D. Path Semantics is often used in combination with [Category Theory] [Logic] etc.

QUESTION
I'm running the following code with Apache POI 4.1.2:
...ANSWER
Answered 2021-Jun-14 at 13:03The color is not stored in the cell but in the cell style. So you need creating as much cell styles as colors are needed.
But also don't simply create a cell style for each cell. There are Excel limits for maximun number of unique cell formats/cell styles. If that limit gets exceeded then the workbook gets corrupt.
So on workbook level create as much cell styles as needed. Then apply those cell styles while filling cell values into the sheet.

QUESTION
I want to fill out the list before passing it as a parameter.
places, it stays in null, I have tried to return it with the function but it tells me that it is not compatible Future to list.
...ANSWER
Answered 2021-Jun-13 at 17:52Your mistake is a misunderstanding of the async
statement of the getPois
method.
async
will allow Dart to delay the execution of the method. It acts somehow like a corouting, which is a non-parallel multitasking. In Flutter, it is used for example to avoid blocking operations (the Flutter/Dart engine can delay async method calls to prioritize screen drawing.
You could check for the existence of your List
after calling await getPois();
.
This explains that you can't return the list. Since your method is marked async
, it has to return a future. So you could make it return a Future>

QUESTION
I'm writing to an MS Word document (.docx) using Apache POI from a JavaFX UI. the String is in Arabic, and when it contains one pair of brackets, the output is okay, but when there are 2 pairs or a quote, the output is messy, even though it appears okay in Eclipse's console too. Here's my code:
...ANSWER
Answered 2021-Jun-13 at 04:52The parentheses are not RTL text as your arabic text is. So it leads to problems if they are not marked as LTR text. See https://en.wikipedia.org/wiki/Bidirectional_text#Table_of_possible_BiDi_character_types.
So either you mark each LTR character using U+200E LEFT-TO-RIGHT MARK
and then RTL characters using U+200F RIGHT-TO-LEFT MARK (RLM)
.
Or you are using U+202E RIGHT-TO-LEFT OVERRIDE (RLO)
before the text line having LTR charcters ((
and )
) and RTL characters mixed and U+202C POP DIRECTIONAL FORMATTING (PDF)
after that text line. That tells the word processing software exactly where RTL starts and ends. That leads to correct output for me.

i've been trying to copy Hebrew data from excel files into a document. while the letters themselves were copied correctly, it got a betty messy whenever some symbols were involved.
for example: instead of (text), i got )text(
this is my code so far:
...ANSWER
Answered 2021-Jun-13 at 04:03Using older word processing software applications there seems to be problems when LTR characters and RTL characters gets mixed in one text run. Then using special BiDi character types might be the solution. See https://en.wikipedia.org/wiki/Bidirectional_text#Table_of_possible_BiDi_character_types.

Using this the following works:

how we can create an excel file (xls) using any java library in a way so that cells are not selectable, i.e.: the user should not be able able to select or copy any of the data.

Answered 2021-Jun-10 at 11:46For anyone who needs to get poi-ooxml up and running, this is my solution.
Maven downloads batik and other dependencies such ad xalan that are not necessary for this to work. Therefore, do not use Maven for this except for a couple of dependencies which I will mention.
Download and extract the official poi binary zip from poi.apache.org
From the downloaded and extracted zip, navigate to the auxiliary folder and modify the META-INF/services/org.apache.batik.script.InterpreterFactory file in the batik-all-1.13.jar using vim or vi. Comment out the line "org.apache.batik.bridge.RhinoInterpreterFactory" and save.
Add all jar files as an external library from the following directories: -auxilliary, lib and ooxml-lib. Add all jars from the poi-5.0.0 directory except for poi-ooxml-full-5.0.0.jar.
From maven, add the following dependencies and you are good to go :

In Angular 10 and TypeScript, I want to drag the marker on the map to send the location on the map with jQuery to a method, and in the output I get the address and title of the position and in a model that I have already defined I put it and double-sided that model with the text box in HTML.

method, but that doesn't always get me the correct results.
I made a screenshot of what I am trying to accomplish.
Example image to illustrate
