Passing template variable to parent in Django
|
<p>I have a number of apps that each have their own intro section. This intro section has quite a few lines of HTML and only a few lines are adjusted for each app (Think title and intro). I would like this intro section to live at the project level (where the navbar template lives), but I can't find a way to pass template variables from the app to the project. </p>
<p>All of my apps(about 15) follow this template scheme:</p>
<pre><code>app_base.html extends project base.html
app_base.html has an {% include %} to pull in app_intro.html
all <app_unique_templates>.html that are called by <app>/views.py, extend the app_base.html
</code></pre>
<p>To reiterate, how can I pass a template variable from /views.py to project base.html template using my app template scheme? If I can't use this scheme, can I adjust it in a way that will allow me to accomplish this?</p>
<p>Thank you all in advance!</p>
<p>views.py:</p>
<pre><code>def add_app_context(view_context):
app_context = {
'app_name': 'Material Database',
'app_desc': 'Long String goes Here For Application Description',
'doc_link': '#',
}
view_context.update(app_context)
return view_context
class MaterialList(ListView):
model = Material
context_object_name = 'materials'
def get_context_data(self):
context = super().get_context_data()
context['pagetitle'] = 'Material List'
context['intro_btn_link'] = '/materials/new'
context['intro_btn_name'] = 'Create New Material'
return add_app_context(context)
</code></pre>
<p>app_base.html:</p>
<pre><code>{% extends "mjd_tools/base.html" %}
{% load staticfiles %}
{% block body %}
<link rel="stylesheet" href="{% static 'mat_db/css/style.css' %}">
{% include "mat_db/app_intro.html" %}
{% block list %}{% endblock list %}
{% block form %}{% endblock form %}
<script src="{% static 'mat_db/js/scripts.js' %}"></script>
{% endblock body %}
</code></pre>
<p>app_intro.html(this is what I have to repeat for each app).</p>
<pre><code><div class="row">
<div class="col-sm-8">
<h1>{{ app_name }}</h1>
</div>
</div>
<hr>
<div class="row">
<div class="col-sm-8">
<p>
{{ app_desc }}
</p>
</div>
<div class="col-auto ml-auto">
<a class="btn btn-warning" role="button" href="{{ doc_link }}">Documentation</a>
</div>
</div>
<hr>
<div class="row">
<div class="col-sm text-center">
<h4>
<span>{{ pagetitle }}</span>
{% if intro_btn_name %}
<a class="btn btn-primary btn-sm pull-right" role="button"
href="{{ intro_btn_link }}">{{ intro_btn_name }}</a>
</h4>
{% endif %}
</div>

Django MTPP display recursive hierarchical category in REST API
|
<p>I am trying to display my recursive category model in my Django REST API list view.
This is how it is now:</p>
<pre><code>"results": [
{
"pk": 3,
"title": "Test",
"category": 7,
},
...
]}
</code></pre>
<p>I want to achieve something like this:</p>
<pre><code>"results": [
{
"pk": 3,
"title": "Test",
"category": [
{
"id": 5,
"name": "Cat",
"slug": "cat",
"child": [
{
"id": 7,
"name": "Parser",
"slug": "parser",
}
]
}
],
},
...
]}
</code></pre>
<p>I am currently using Django MPTT to create a hierarchical Model. This is the Category in models.py:</p>
<pre><code>class Category(MPTTModel):
name = models.CharField(max_length=50, unique=True)
parent = TreeForeignKey('self', null=True, blank=True, related_name='children', db_index=True, on_delete=models.SET_NULL)
slug = models.SlugField()
class MPTTMeta:
order_insertion_by = ['name']
class Meta:
unique_together = (('parent', 'slug',))
verbose_name = "Category"
verbose_name_plural = "Categories"
def get_slug_list(self):
try:
ancestors = self.get_ancestors(include_self=True)
except:
ancestors = []
else:
ancestors = [i.slug for i in ancestors]
slugs = []
for i in range(len(ancestors)):
slugs.append('/'.join(ancestors[:i + 1]))
return slugs
def __str__(self):
return self.name
</code></pre>
<p>I am using generic views from Django Rest Framework to create the view. In views.py:</p>
<pre><code>class CaseListCreateView(generics.ListCreateAPIView):
serializer_class = CaseSerializer
def get_queryset(self):
qs = Case.objects.filter(active=True)
query = self.request.GET.get("search")
if query is not None:
qs = qs.filter(Q(title__contains=query) | Q(text__contains=query)).distinct()
return qs
def perform_create(self, serializer):
serializer.save(user=self.request.user)
</code></pre>
<p>I have tried <a href="https://github.com/heywbj/django-rest-framework-recursive" rel="nofollow noreferrer">using djangorestframework-recursive</a> to make the recursion but with no luck. </p>
<p>Any help would be greatly appriciated!
Thanks</p>

Extract data from xml file in C#
|
<p>I need to extract data from a XML file for my project based on C#.
The XML file is like this :</p>
<pre><code><?xml version="1.0" encoding="utf-8" ?>
<Chemicals>
<Titrates>
<Titrate Name="Hydrochloric Acid" Basisity="1" Molarity="10" Normality="10" >
<Experiments>
<Experiment Name="AcidBase"></Experiment>
<Experiment Name="Redox"></Experiment>
</Experiments>
</Titrate>
<Titrate Name="Sulphuric Acid" Basisity="2" Molarity="20" Normality="50" >
<Experiments>
<Experiment Name="AcidBase"></Experiment>
</Experiments>
</Titrate>
<Titrate Name="Nitric Acid" Basisity="3" Molarity="50" Normality="40" >
<Experiments>
<Experiment Name="AcidBase"></Experiment>
</Experiments>
</Titrate>
</Titrates>
<Titrants>
<Titrant Name="Sodium Hydroxide" Acidity="1" Molarity="10" Normality="20" >
<Experiments>
<Experiment Name="AcidBase"></Experiment>
</Experiments>
</Titrant>
<Titrant Name="Calcium Hydroxide" Acidity="1" Molarity="20" Normality="40" >
<Experiments>
<Experiment Name="AcidBase"></Experiment>
</Experiments>
</Titrant>
</Titrants>
<Indicators>
<Indicator Name="Phenolphethalin" Color="Pink" >
<Experiments>
<Experiment Name="AcidBase"></Experiment>
</Experiments>
</Indicator>
<Indicator Name="Methyl Orange" Color="Orange" >
<Experiments>
<Experiment Name="AcidBase"></Experiment>
</Experiments>
</Indicator>
</Indicators>
</Chemicals>
</code></pre>
<p>As you can see, The chemicals are divided under titrants, titrates and indicators and then each chemical may be used in multiple experiments.
The file is just a sample so, please ignore the chemistry aspect :P.
So, for a particular experiment I need to extract the relevant data of all the chemicals that will be used in it.</p>
<p>Example:</p>
<p>For AcidBase Titration I would need the Name, Molarity, Basisity etc ( under titrates ) of the particular titrate. Same way for titrants and indicators whichever have AcidBase in their Experiment part.</p>

<p>How to resolve problem?</p>

jquery next() returning nothing
|
<p>I was trying to select everything between adjacent <code><p></code>'s, the number of "p" changes every time. And contents in between p tag-pairs could be nothing to anything. Some thing like this:</p>
<pre><code> <p><a href="x">...ABC...</a></p>
<<<<<<<< Beginning of what I want >>>>>>>>
<fieldset>...</fieldset>
<font title="...">...</font>
sometext without any tag<br>
<a href="...">...</a>
//[0..N] more tags
<<<<<<<< End of what I want >>>>>>>>
<p><a href="x+1">...ABC...</a></p>
[0..N] more "p"'s with similar pattern ("p" with random url in "a")
</code></pre>
<p>Update:</p>
<p>I want to wrap those rogue codes (untagged text) into some div so that I can process them later. Like this:</p>
<pre><code><div id="outer">
<div id="1">
<p><a href="x">...ABC...</a></p>
<! Beginning of what I want >
<fieldset>...</fieldset>
<font title="...">...</font>
sometext without any tag<br>
<a href="...">...</a>
//[0..N] more tags
<! End of what I want >
</div>
<div id="2">
<p><a href="x+1">...ABC...</a></p>
</div>
<div id="3">
//something or nothing
</div>
//something or nothing
</div>
</code></pre>
<p>In order to do that, I had to this code because there is some text without any tags around it:</p>
<pre><code> var ps = $("p:contains('ABC')");
ps.each(function(){
if(!($(this).next()[0])){
return true;
}
var me = $(this);
var pa = me.parent().contents();
var nx = me.next("p:contains('ABC')"); //returns [] in this case
var i0 = pa.index(me);
var i1 = pa.index(nx);
if (i1 > i0) {
var elements = pa.slice(i0, i1);
elements.each(function(){
//Do something
});
}
});
</code></pre>
<p>As marked in the code, the next() function would not return anything even if I change it to next("p"). But if I use me.next().next().next().next().next() I can select the next "p" tag. Why would this happen? How could I do it better? </p>

Intent Activity not firing?

<p>I'm doing a basic activity of moving from one page to another. Everything was going perfect until I get two pages deep into the app. I used the same exact code for each page class, put the activities in the manifest and made sure all words were spelled correctly, etc., but the intent doesn't do anything when I try to go three pages deep. There are no error messages in the log at all. When I click on a button on the third page, it just turns blue but doesn't move to the next page like the previous pages. Here's my code:</p>
<p>from page 1 to 3:</p>

Different Ising Model results with Fortran and F2PY
|
<p>I am trying to implement my Fortran code in python using 'f2py'. I derived/extracted a Fortran subroutine from my original Fortran code of Ising model and did calculation using both with same lattice parameters/conditions, etc. But my results are different, which I am unable to understand. Since both should result in similar curves.</p>
<p><strong>Output:</strong></p>
<ol>
<li>Lattice dimensions = 64 x 64</li>
<li>Temperature range 0.1 - 5.0</li>
<li>External Magnetic Field b = 0</li>
<li>coupling constant j = 0</li>
<li>No. of MonteCarlo Simulations = 100 + 50</li>

Keypress detection wont work after seemingly unrelated code change
|
<p>I'm trying to have the Enter key cause a new 'map' to generate for my game, but for whatever reason after implementing full-screen in it the input check won't work anymore. I tried removing the new code and only pressing one key at a time, but it still won't work.</p>
<p>Here's the check code and the method it uses, along with the newMap method:</p>
<pre><code>public class Game1 : Microsoft.Xna.Framework.Game
{
// ...
protected override void Update(GameTime gameTime)
{
// ...
// Check if Enter was pressed - if so, generate a new map
if (CheckInput(Keys.Enter, 1))
{
blocks = newMap(map, blocks, console);
}
// ...
}
// Method: Checks if a key is/was pressed
public bool CheckInput(Keys key, int checkType)
{
// Get current keyboard state
KeyboardState newState = Keyboard.GetState();
bool retType = false; // Return type
if (checkType == 0)
{
// Check Type: Is key currently down?
retType = newState.IsKeyDown(key);
}
else if (checkType == 1)
{
// Check Type: Was the key pressed?
if (newState.IsKeyDown(key))
{
if (!oldState.IsKeyDown(key))
{
// Key was just pressed
retType = true;
}
else
{
// Key was already pressed, return false
retType = false;
}
}
}
// Save keyboard state
oldState = newState;
// Return result
return retType;
}
// Method: Generate a new map
public List<Block> newMap(Map map, List<Block> blockList, Console console)
{
// Create new map block coordinates
List<Vector2> positions = new List<Vector2>();
positions = map.generateMap(console);
// Clear list and reallocate memory previously used up by it
blockList.Clear();
blockList.TrimExcess();
// Add new blocks to the list using positions created by generateMap()
foreach (Vector2 pos in positions)
{
blockList.Add(new Block() { Position = pos, Texture = dirtTex });
}
// Return modified list
return blockList;
}
// ...
}
</code></pre>
<p>I never touched any of the above code for this when it broke - changing keys won't seem to fix it. Despite this, I have camera movement set inside another Game1 method that uses WASD and works perfectly. All I did was add a few lines of code here:</p>
<pre><code>private int BackBufferWidth = 1280; // Added these variables
private int BackBufferHeight = 800;
public Game1()
{
graphics = new GraphicsDeviceManager(this);
graphics.PreferredBackBufferWidth = BackBufferWidth; // and this
graphics.PreferredBackBufferHeight = BackBufferHeight; // this
Content.RootDirectory = "Content";
this.graphics.IsFullScreen = true; // and this
}
</code></pre>
<p>When I try adding text to be displayed in the event the key is pressed, it seems that the If is never even triggered despite the correct key being pressed.</p>
<p>It seems that when the CheckInput method attempts to check for 'Enter' having just been pressed, it passes the first check <code>if (newState.IsKeyDown(key))</code> (which returns true) but fails the second <code>if (!oldState.IsKeyDown(key))</code> check. (and returns true, but shouldn't)</p>

Swapping rows in 2-D array C++
|
<p>So yeah, I wrote a program which sort rows of two-dimensional array in ascending order according to sum of all positive even elements in every row, BUT it does not work properly. Sometimes it can swap rows correctly but mostly it feels like this program only swap two adjacent rows or something like that.</p>
<p>Probably, there is a problem with incorrect using bubble sort for 2-d arrays. Here is the function where I did most things:</p>
<pre><code>void print(int** arr, int rows, int columns) {
for (int i = 0; i < rows; i++) {
for (int j = 0; j < columns; j++) {
cout << setw(7) << arr[i][j];
}
cout << endl;
}
int* sumRows = new int[rows];
int sum = 0;
for (int i = 0; i < rows; i++) {
for (int j = 0; j < columns; j++) {
if (arr[i][j] > 0 && arr[i][j] % 2 == 0)
{
//cout << setw(7) << arr[i][j];
sum = sum + arr[i][j];
}
}
cout << endl << "Sum of positive even elements in the row " << i + 1 << " = " << sum;
sumRows[i] = sum;
sum = 0;
}
cout << endl << "Array of sums: ";
for (int i = 0; i < rows; i++) {
cout << setw(7) << sumRows[i];
}
//for (int i = 0; i < r; i++) cout << setw(7) << sumRows[i];
cout << endl;
bool swapped;
for (int i = 0; i < rows - 1; i++)
{
swapped = false;
for (int j = 0; j < columns - 1; j++)
{
for (int k = 0; k < rows - i - 1; k++) {
if (sumRows[k] > sumRows[k + 1])
{
swap(arr[k][j], arr[k + 1][j]);
swapped = true;
}
}
}
if (swapped == false) break;
}
cout << endl << endl << "Swapped array:" << endl;
for (int i = 0; i < rows; i++) {
for (int j = 0; j < columns; j++) {

<p>P.S. Two-dimensional arrays must be necessarily dynamic ones. Besides, I needed to give user a choice of creating an array with <code>malloc</code>, <code>calloc</code> or <code>new</code>. Also, cannot do this task using <code>vector</code> yet.</p>
<p>P.P.S. I know that most of you will find it easy but for me it is definitely not as this task is my homework in a university and we have not learnt any sorting algorithms. Anyway, when I asked the teacher how can I sort rows like that, he told me to use bubble sort so here I am</p>

What is the best way to compare time periods and how do I structure my database for it?
|
<p>I'm looking for a way, that if my app says "Looking for person available from <strong>March 3rd, 2016 8:00 am to March 3rd, 2016 3:00 pm</strong>" to match it with a person that might be available from <strong>March 3rd, 2016 7:00 am to March 3rd, 2016 16:00 pm.</strong></p>
<p>Now this is a just a snapshot, it has to scale for infinite times/dates for example a person might be available from <strong>March 3rd, 2016 7:00 am to 9:00 am, then again from 2:00pm to 8:00pm</strong>, so I'd have to have a way to filter people like this as a not complete match.</p>
<p>What I have so far is ONE TABLE that holds the dates to match against, so for example March 3rd 8 - 3pm, March 4th 8 - 3pm, March 5th 8 - 3pm..etc..</p>
<p>Another table that holds people and their availability as child elements, but I am not sure how to structure this part to make it easy and efficient to match inside loops with the other table.</p>
<p>Right now, in my employee table I have one field "March 3rd" and then another field with hours/minutes available as an array so for example "8:00, 8:15, 8:30, 8:45, 9:00...etc... The hours increments have to be in 15 min periods, so I can't just put 8am - 5pm for example...especially if the person is available during certain periods of the day...</p>
<p>Here is what my "employee select your availability looks like" </p>

How to use REST API mark tests as fail?

<p>I use this <a href="https://www.browserstack.com/docs/automate/selenium/view-test-results/mark-tests-as-pass-fail" rel="nofollow noreferrer">https://www.browserstack.com/docs/automate/selenium/view-test-results/mark-tests-as-pass-fail</a> as reference.
But I not able to let the REST API shows 'fail'. May I know what is my problem? I also attached the text logs, it shows 'Run JavaScript......'
, is it correct?</p>

React/Redux Can't update initial state / undefined problem
|
<p>I am trying to update my state and getting it to render.</p>
<p>Below I am calling my state from the reducer.js file and displaying the initial list fine.</p>
<pre><code><div className={classes.resultborder}>
{this.props.transInput.map(data => {
return (
<Inputs
key={data.id}
xParty={data.xParty}
zParty={data.zParty}
yAction={data.yAction}
amount={data.amount}
deleteItem={() => this.deleteItem(data.id)}/>
);
})}
</div>
</code></pre>
<p>At the bottom of my parent app, I have</p>
<pre><code>const mapStateToProps = state => {
return {
transInput: state.transactionInputs
};
};
const mapDispatchToProps = dispatch => {
return {
submitResults: () => dispatch({type: 'SUBMIT', x: {
xParty: 'Henry',
yAction: 'Funds',
zParty: 'Elizbath'
}})
};
};
export default connect(mapStateToProps, mapDispatchToProps)(Transactions);
</code></pre>
<p>I have hard coded my <code>submitResults</code> because I have not yet been able to update my state and display, this is for simplicity.</p>
<p>I am calling <code>submitResults</code> in a button</p>
<pre><code>submitResults={this.props.submitResults}
</code></pre>
<p>Now below is my whole reducer</p>
<pre><code>const initialReducer = {
transactionInputs: [
{id: 1, xParty: "statePaul", yAction: "Funds", zParty: "stateSandra", amount: 100},
{id: 2, xParty: "stateEmily", yAction: "Loans", zParty: "stateJohn", amount: 200},
{id: 3, xParty: "stateMatt", yAction: "Repays", zParty: "stateMicheal", amount: 300},
],
emptyInputs: false,
toggle: false
};
const reducer = (state = initialReducer, action) => {
console.log(initialReducer.transactionInputs);
if(action.type === 'SUBMIT'){
return{
...state,
xParty: state.xParty.concat(action.x)
}
}
return state;
};
export default reducer;
</code></pre>
<p>When I press te button to run <code>submitResults</code> I get the following error message <code>TypeError: Cannot read property 'concat' of undefined</code></p>
<p>I want to be able to update my initial state and have it displayed (currently I do believe if I can get the initial state to update then the display will re-render fine).</p>
<p>I am not completely sure why this is not working but I do believe it's in my reducer.js file has something to dow ith how I'm returning my state.</p>
<p>I apprentice any suggestions.</p>

Hashing collision keys to next in the hashtable

Rails Associations - Creating a new record through a form with belongs_to

<p>I have a Course model:</p>
<pre><code>class Course < ApplicationRecord

end
</code></pre>
<p>On the <code>courses.show.html</code> (specific course page e.g. admin/courses/1) I have a button that links to a new sub course page</p>
<pre><code>%table

%td= @course.description
= button_to "Add New Sub Course", new_admin_sub_course_path(course_id: @course.id), method: :post

CALayer.draw(in:) and CALayer.needsDisplay(forKey:) not called when expected, presentation layer unexpectedly nil
|
<p>I'm trying to implement a layer with implicitly animated properties, and I am seeing some very strange behavior. Here's a simple layer that demonstrates what I mean:</p>
<pre><code>class CustomLayer: CALayer {
override init() {
super.init()
implcitlyAnimatedProperty = 0.0000
needsDisplayOnBoundsChange = true
}
override init(layer: Any) {
super.init(layer: layer)
implcitlyAnimatedProperty = (layer as! CustomLayer).implcitlyAnimatedProperty
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
}
@NSManaged
var implcitlyAnimatedProperty: CGFloat
override func action(forKey event: String) -> CAAction? {
if event == "implcitlyAnimatedProperty" {
let action = CABasicAnimation(keyPath: event)
action.fromValue = presentation()?.value(forKey: event) ?? implcitlyAnimatedProperty
return action
} else {
return super.action(forKey: event)
}
}
override class func needsDisplay(forKey key: String) -> Bool {
if key == "implcitlyAnimatedProperty" {
return true
} else {
return super.needsDisplay(forKey: key)
}
}
override func draw(in ctx: CGContext) {
if presentation() == nil {
print("presentation is nil")
}
print(presentation()?.value(forKey: "implcitlyAnimatedProperty") ?? implcitlyAnimatedProperty)
}
}
</code></pre>
<p>I create an instance of <code>CustomLayer</code> and attempt to animate the property implicitly like this: </p>
<pre><code> let layer = CustomLayer()
view.layer.addSublayer(layer) // I'm doing this in a view controller, when a button is pressed
CATransaction.begin()
CATransaction.setDisableActions(false)
CATransaction.setAnimationDuration(10)
layer.implcitlyAnimatedProperty = 10 // (1)
layer.bounds = CGRect(x: 0, y: 0, width: 100, height: 100) // (2)
CATransaction.commit()
</code></pre>
<p>The behavior that I'm seeing is as follows:</p>
<ul>
<li>With the code exactly as it's written above, the first time <code>draw(in:)</code> is called, <code>presentation()</code> returns <code>nil</code>, which, in my real app, makes the layer draw once with the final values from the model layer, which is an undesirable visual artifact. Otherwise, everything works as expected.</li>
<li>With (2) commented out, <code>needsDisplay(forKey:)</code> is never called after the layer is created, and <code>draw(in:)</code> is never called. <code>action(forKey:)</code> <em>is</em> called, however. </li>
</ul>
<p>A common explanation for these functions not being called is that the layer has a delegate which is handling these calls on its behalf. But the layer's delegate is nil here, so that can't be what's happening. </p>
<p>Why is this happening, and how can I fix it? </p>

Java, Apache POI, XSSFWorkbook extremly slow
|
<p>I use Apache POI to read an excel file (xlsx)
This works fine in Eclipse. 30.000 rows and 20 cols are no problem. Loaded after around 5 seconds.</p>
<p>If I generate a runnable JAR File it doesnt process the excel file</p>
<pre><code> try {
soeArraylist.clear();
//JOptionPane.showMessageDialog(null, "SoE Pre Test 1", "Done" , JOptionPane.INFORMATION_MESSAGE);
//Workbook workbook2 = new XSSFWorkbook();
//JOptionPane.showMessageDialog(null, "SoE Pre Test 2", "Done" , JOptionPane.INFORMATION_MESSAGE);
JOptionPane.showMessageDialog(null, "SoE Import started 1", "Done" , JOptionPane.INFORMATION_MESSAGE);
FileInputStream excelFile = new FileInputStream(new File(FILE__NAME));
JOptionPane.showMessageDialog(null, "SoE Import started 2 " + FILE__NAME, "Done" , JOptionPane.INFORMATION_MESSAGE);
Workbook workbook = new XSSFWorkbook(excelFile);
JOptionPane.showMessageDialog(null, "SoE Import started 3", "Done" , JOptionPane.INFORMATION_MESSAGE);
Sheet datatypeSheet = workbook.getSheet("SoE");
JOptionPane.showMessageDialog(null, "SoE Import started 4", "Done" , JOptionPane.INFORMATION_MESSAGE);
Iterator<Row> iterator = datatypeSheet.iterator();
JOptionPane.showMessageDialog(null, "SoE Import started 5", "Done" , JOptionPane.INFORMATION_MESSAGE);
DataFormatter formatter = new DataFormatter(Locale.US);
//JOptionPane.showMessageDialog(null, "SoE Import started 6", "Done" , JOptionPane.INFORMATION_MESSAGE);
JOptionPane.showMessageDialog(null, "File opened", "Done" , JOptionPane.INFORMATION_MESSAGE);
while (iterator.hasNext()) {

} catch (IOException e) {
e.printStackTrace();
JOptionPane.showMessageDialog(null, "SoE Import IOException", "IOException" , JOptionPane.INFORMATION_MESSAGE);
}
</code></pre>
<p>So its stopps after SoE Import "started 2"
OK it does not stopp but it looks like its processing for ages. After 1 hour still no result.</p>
<p>I tried to create an empty Workbook and this last 20 seconds outside from Eclipse. In Eclipse it is less than 1 second</p>
<pre><code> JOptionPane.showMessageDialog(null, "SoE Pre Test 1", "Done" , JOptionPane.INFORMATION_MESSAGE);
Workbook workbook2 = new XSSFWorkbook();
JOptionPane.showMessageDialog(null, "SoE Pre Test 2", "Done" , JOptionPane.INFORMATION_MESSAGE);
</code></pre>
<p>Java is 1.8 in Eclipse and also on the W10 machine.
I know there are some similar questions here but non of them have different times between Eclipse and as standalone JAR.</p>
<p>Any Ideas ?</p>

Need to check for login username and password, and then bring data from previous entries

<p>Following this question I had asked previously (<a href="https://stackoverflow.com/questions/65717284/need-to-query-google-sheet-for-specific-data-from-google-apps-script">Need to Query Google Sheet for specific data from Google Apps Script</a>).</p>
<p>I have created a web app to track the working hours of employees at my company, the web app is simple, it first asks them to provide their username and a password, and then allows them to register their time of entry o their exit time. Now, I need to find a way to check for a match between username and password (in a data base), and if this is true, bring information about that employee's last submission to the web app, this last submission data is found on another sheet that receives the data from the web app.</p>
<p>Here is a minimal reproducible example, where its just asks for a name and a password, and if correct, show another display, where it brings the timestamp of that user's last submission to the web app.</p>

Save ArrayList of custom objects and add a new object to ArrayList
|
<p>I'm having an issue with saving the instance of an ArrayList of custom objects in an Activity and then retreiving it after doing some stuff in another Activity. Inside the first Activity (which has the ArrayList), there is a button to start a second activity. Inside this second Activity the user is asked to create a new object that will be added afterwards in the ArrayList of the first Activity, so that when the second Activity finishes the first Activity is shown again with a ListView of all the objects (including the last one created). The problem I'm facing is that only the last object created is being shown in the ListView.</p>
<p>Here is the code of the first Activity: </p>
<pre><code>public class CargasMin extends AppCompatActivity implements View.OnClickListener {
RelativeLayout rl_CargasMin;
ImageButton bt_AdDep;
Button bt_CalcCargas;

// This seems not to be working!

A comparison of different methods to condense a list of repetitive values in python (Maintaining order & count of repetitions)
|
<p>I needed a Python script to condense a list of values and wasn't sure of the best method to accomplish this. The functions below are a collection of the different approaches that were recommended to me and their associated runtimes. For reference, my source data for these benchmarks used 100 lists of approx 500,000 entries each</p>
<p>Thanks to everyone who pointed me in the right direction!</p>
<p><strong>Sample Input:</strong></p>
<pre><code>values = [3, 4, 4, 5, 3, 2, 7, 8, 9, 9, 9, 9, 9, 4, 4, 2, 1, 1]
</code></pre>
<p><strong>Desired output:</strong></p>
<pre><code>col_counts = [1, 2, 1, 1, 1, 1, 1, 5, 2, 1, 2]
col_values = [3, 4, 5, 3, 2, 7, 8, 9, 4, 2, 1]
Output String = 1*3 2*4 1*5 1*3 1*2 1*7 1*8 5*9 2*4 1*2 2*1
</code></pre>
<p><strong>Summary Findings:</strong></p>
<ul>
<li>Using Pandas was very similar in speed to manually iterating over the list</li>
<li>Using itertools with <strong>(k, len(list(g)))</strong> was actually <strong>2x</strong> faster than <strong>(k, sum(1 for i in g)</strong></li>
<li>Using itertools w/ len was by far the fastest method (<strong>5x</strong> faster than pandas or manual loop)</li>
<li>The fastest method was also the most compact; it required only 2 lines to build the output string (vs. 28 in my original)</li>
</ul>
<p><strong>Code for Fastest Method:</strong></p>
<pre><code>def condense_values_2liner(values):
grouped_values = [(len(list(g)), k) for k,g in groupby(values)]
output_str = " ".join("%s*%s" % tup for tup in grouped_values)
return output_str
</code></pre>
<p><strong>Complete Code for other Methods:</strong></p>
<pre><code># BENCHMARKED PERFORMANCE (100 LISTS OF APPROX. 500,000 values
# > condense_values_loop = 21.7s
# > condense_values_pandas = 21.2s
# > condense_values_itertools_sum = 10.4s

Yeoman angular generator and bootstrap templates
|
<p>So, I have an application that I have built using <strong>yo angular</strong> and all has been working for a while.
I have overridden some of the bootstrap templates (specifically the <strong>datepicker</strong>) and I have updated my grunt task to include these files when creating my templateCache:</p>
<pre><code>ngtemplates: {
dist: {
options: {
module: 'sapphire',
htmlmin: '<%= htmlmin.dist.options %>',
usemin: 'scripts/scripts.js'
},
cwd: '<%= yeoman.app %>',
src: [
'app/**/*.html',
'uib/**/*.html'
],
dest: '.tmp/templateCache.js'
}
},
</code></pre>
<p>The problem is when locally testing. It doesn't use the new template, which is annoying.
I have been using <strong>injector</strong> to inject my project files into my <strong>index.html</strong>, so I created this:</p>
<pre><code>html: {
options: {
transform: function (filePath) {
return '<script type="text/ng-template" src="\'' + filePath.replace('/src/', '') + '\'"></script>';
}
},
files: {
'<%= yeoman.app %>/index.html': [
'<%= yeoman.app %>/uib/**/*.html'
]
}
},
</code></pre>
<p>Which adds my templates to the bottom of the <strong>index.html</strong> like this:</p>
<pre><code><!-- injector:html -->
<script type="text/ng-template" src="'uib/template/datepicker/datepicker.html'"></script>
<script type="text/ng-template" src="'uib/template/datepicker/day.html'"></script>
<script type="text/ng-template" src="'uib/template/datepicker/month.html'"></script>
<script type="text/ng-template" src="'uib/template/datepicker/year.html'"></script>
<script type="text/ng-template" src="'uib/template/timepicker/timepicker.html'"></script>
<script type="text/ng-template" src="'uib/template/typeahead/typeahead-account-match.html'"></script>
<script type="text/ng-template" src="'uib/template/typeahead/typeahead-complaint.html'"></script>
<script type="text/ng-template" src="'uib/template/typeahead/typeahead-customer-services.html'"></script>
<script type="text/ng-template" src="'uib/template/typeahead/typeahead-match.html'"></script>
<script type="text/ng-template" src="'uib/template/typeahead/typeahead-order-match.html'"></script>
<script type="text/ng-template" src="'uib/template/typeahead/typeahead-product-match.html'"></script>
<script type="text/ng-template" src="'uib/template/typeahead/typeahead-stock-match.html'"></script>
<script type="text/ng-template" src="'uib/template/typeahead/typeahead-user-match.html'"></script>
<!-- endinjector -->
</code></pre>
<p>These templates are put under the <strong>JavaScript</strong> files.
I have tried them above and still it doesn't work. Does anyone know why?</p>

Using JAVA to save data to Oracle table with TIMESTAMP WITH ZONED TIME column
|
<p>I am trying to find a Java Time Type that can be persisted to a column of type TIMESTAMP WITH TIME ZONE in the Oracle DB. The Java type needs to have the Time Zone as part of it. Because of the way the application was written, the Java Calendar type was used (also, the Java Calendar type has Time Zone that is part of it)</p>
<p><strong>TRIAL ONE:</strong></p>
<p>I did try to use the Calendar directly (with no serializer) with this code:</p>
<p>dateStr was in a pattern of: <code>"MM-dd-yyyy hh:mm:ss a"</code>
ZoneLoc was for the timezone: ex: <code>America/Chicago</code>, <code>US/Eastern</code>, etc.</p>
<pre><code>public Calendar convDateStrWithZoneTOCalendar(String dateStr,
String ZoneLoc) throws Exception {
String string = dateStr;
String pattern = this.getPattern();
Date date = new SimpleDateFormat(pattern).parse(string);
Calendar calendar = Calendar.getInstance();
calendar.setTime(date);
TimeZone tz = TimeZone.getTimeZone(ZoneLoc);
calendar.setTimeZone( tz );
return calendar;
}
</code></pre>
<p>when using this, the correct Zone Location was not set. For example, I would try to set ZoneLoc to US/Hawaii and when data was saved to the DB, it would be something like
23-SEP-19 10.03.11.000000 AM -05:00 And (-05:00) does not represent US/Hawaii</p>
<p><strong>TRIAL TWO</strong></p>
<p>It is for this reason why the attribute-conversion route was tried. In this case, there is an attempt to convert Calendar to ZoneDateTime. </p>
<p>I had seen this in another message noting: </p>
<blockquote>
<p>Add @Convert(converter=OracleZonedDateTimeSeriliazer.class) on top of
your createdOn attribute on ur Entity class.</p>
</blockquote>
<p>But, as mentioned above, Calendar is being used as part of the entity and not ZonedDateTime</p>
<p><strong>the way the entity class is defined now. Before (when using the ( convDateStrWithZoneTOCalendar above), the "@Convert" items were not present</strong></p>
<pre><code>@Entity
@Table(name = "LAWNCORRJOB", schema = "ORAAPPS", uniqueConstraints = @UniqueConstraint(columnNames = {
"TENANTID", "GENERATEDJOBNO" }))
public class Lawncorrjob implements java.io.Serializable {
private static final long serialVersionUID = -8207025830028821136L;
....
@Convert( converter = OracleCalendarZoneDateTimeSerializer.class, disableConversion = false )
private Calendar schedfirstdayts;
@Convert( converter = OracleCalendarZoneDateTimeSerializer.class, disableConversion = false )
private Calendar schedlastdayts;
...
}
</code></pre>
<p><strong>the converter being used: converts Calendar to ZonedDateTime (under Oracle)</strong></p>
<pre><code>@Converter(autoApply = true)
public class OracleCalendarZoneDateTimeSerializer implements
AttributeConverter<Calendar, ZonedDateTime> {
@Override
public ZonedDateTime convertToDatabaseColumn(Calendar attribute) {
if (attribute == null)
return null;
// get the timezone
TimeZone tz = attribute.getTimeZone();
// use the timezone to specify the area location
// ex: For example, TimeZone.getTimeZone("GMT-8").getID() returns
// "GMT-08:00".
ZonedDateTime xzdt = ZonedDateTime.of(attribute.get(Calendar.YEAR),
attribute.get(Calendar.MONTH),
attribute.get(Calendar.DAY_OF_MONTH) + 1,
attribute.get(Calendar.HOUR_OF_DAY),
attribute.get(Calendar.MINUTE), attribute.get(Calendar.SECOND),
attribute.get(Calendar.MILLISECOND), ZoneId.of(tz.getID()));
return xzdt;
}
@Override
public Calendar convertToEntityAttribute(ZonedDateTime dbData) {
GregorianCalendar newcal = DateTimeUtils.toGregorianCalendar(dbData);
return newcal;
}
}
</code></pre>
<p>But, when executing this code, I get an error:</p>
<blockquote>
<p>Error Message: Could not commit JPA transaction; nested exception is
javax.persistence.RollbackException: Error while committing the
transaction CAUSE : javax.persistence.RollbackException: Error while
committing the transaction",</p>
</blockquote>
<p>So, is there any way I can fix either option to get this all working?</p>
<p>Any help, hints or advice is appreciated.</p>
<p>TIA</p>

JQGrid 5.1 - getCell returns entire html instead of selected Combo box value
|
<p>My project is Spring MVC + Hibernate + MySQL and JSP and JQGrid 5.1 as a front end. I am facing typical situation where, in JQGrid <strong>delete row</strong> functionality, I want to pass two more parameters to controller in addition to 'oper' and 'id'. One parameter is string and I am able to pass it without any issue, however another parameter is a selected value from the combo box, here in the following code segment, I get the entire HTML instead of simple selected value of combo box item.</p>
<p>resultant HTML which I am getting as a selected value of 'cmpcode' is as below:</p>
<pre><code><select role="select" class="editable inline-edit-cell ui-widget-content ui-corner-all" id="3_cmpcode" name="cmpcode" rowid="3">null<option value="1" role="option">Test Company</option><option value="2" role="option">Test-2-new</option><option value="3" role="option">Niyogi Enterprise</option><option value="4" role="option">Test-4</option><option value="5" role="option">SySoft Computers</option><option value="6" role="option">Rohi-Nirag</option><option value="7" role="option">TYB and Co</option></select>
</code></pre>
<p>Code segment for delete row is as below:</p>
<pre><code> {
caption: "Delete Branch Master",
msg: "Delete selected Branch?",
bSubmit: "Delete",
bCancel: "Cancel",
reloadAfterSubmit:true,
closeOnEscape:true,
onclickSubmit : function(eparams) {
var rowData = $("#list").jqGrid('getRowData', row_selected);
var retarr = {'brcode':rowData['brcode'],'cmpcode':rowData['cmpcode']};
return retarr;
}
</code></pre>
<p>Here, cmpcode is a combo box in JQGrid and its model is as below:</p>
<pre><code>colModel:[
{name:'brcode',index:'brcode', width:50, editable:true, editrules:{required:true}, editoptions:{size:10}, formoptions:{elmprefix:'*'}},

list<lab_result_cash_view> does not contain a definition for 'Patient_Name ' and no extension method 'Patient_Name '

<p>I want to select data from multiple tables and view.
I created the following class Orders tables:</p>
<pre><code>public class Orders_Tables
{
public List<Lab_Orders> LabOrders { get; set; }
public List<Lab_orders_Cash> LabOrdersCash { get; set; }
public List<Lab_Sample_status> LabOrderStatus { get; set; }
public List<LAB_RESULTS> LabResults { get; set; }
public List<LabTests> labtests { get; set; }
public List<LAB_RESULTS_CLINIC_VIEW> labViewResult { get; set; }
public List<LAB_RESULT_CASH_VIEW> labCashView { get; set; }
public List<LAB_PARASITOLOGY_VIEW> labparaview { get; set; }
public List<Lab_Hematology_Samples> LabSamples { get; set; }
public List<Patients> patients { get; set; }
public Orders_Tables()
{
this.LabOrders = new List<Lab_Orders>();
this.LabOrdersCash = new List<Lab_orders_Cash>();
this.LabOrderStatus = new List<Lab_Sample_status>();
this.LabResults = new List<LAB_RESULTS>();
this.labtests = new List<LabTests>();
this.labViewResult = new List<LAB_RESULTS_CLINIC_VIEW>();
this.labCashView = new List<LAB_RESULT_CASH_VIEW>();
this.labparaview = new List<LAB_PARASITOLOGY_VIEW>();
this.LabSamples = new List<Lab_Hematology_Samples>();
this.patients = new List<Patients>();
}
}
</code></pre>
<p>And this is the controller : </p>
<pre><code>public ActionResult Cash(int id)
{
Orders_Tables tables = new Orders_Tables();
tables.labCashView = db.LAB_RESULT_CASH_VIEW.Where(c => c.order_number == id).ToList();
tables.labparaview = db.LAB_PARASITOLOGY_VIEW.Where(p => p.ORDER_ID == id).ToList();
return View(tables);
}
</code></pre>
<p>Then I created empty view , the error when i try to select columns i cannot find it and the error appeared when i paste the column name , this is the view code :</p>
<pre><code>@model IEnumerable<AljawdahNewSite.Models.Orders_Tables>

<p>The error appeared when i paste the column name : Patient_Name , Customer_Name and so on ...</p>
<blockquote>

BOOST_ASSERT failure raised in boost::fiber on Visual Studio "Debug" build
|
<p>I run into issue with boost::fiber. My code is based on "work_stealing.cpp" example of boost::fiber. I decorated it a little bit. It can work now on Windows Subsystem Linux Ubuntu for both Debug and Release build. In fact, till last night it can work on Windows Visual Studio build... But today, we I attempt to run some test, a BOOST ASSERT failure raised on Debug build. The Release build can work...</p>
<p>I don't know why... so, do anyone know something about this? Why it's only on Windows Debug build? What did I do wrong?</p>
<p>I am using cmake as build tool, Visual Studio 2019 Community Edition as development tool. I also test on WSL Ubuntu 20.04 and macOS 10.15.x(cannot recall it...).</p>

Setup torque/moab cluster to use multiple cores per node with a single loop
|
<p>This is a followup on [<a href="https://stackoverflow.com/questions/17288379/how-to-set-up-dosnow-and-sock-cluster-with-torque-moab-scheduler/17299302?noredirect=1#comment44364759_17299302]">How to set up doSNOW and SOCK cluster with Torque/MOAB scheduler?</a></p>
<p>I have a memory limited script that only uses 1 <code>foreach</code> loop but I'd like to get 2 iterations running on node1 and 2 iterations running on node2. The above linked question allows you to start a SOCK cluster to each node for the outer loop and then MC cluster for the inner loop and I think doesn't make use of the multiple cores on each node.
I get the warning message
<code>Warning message:
closing unused connection 3 (<-compute-1-30.local:11880)</code></p>
<p>if I do <code>registerDoMC(2)</code> if I do this after <code>registerDoSNOW(cl)</code>
Thanks.</p>
<p>EDIT: The solution from the previous question works fine for the problem asked. see my example below for what I want.</p>
<p>starting an interactive job with 2 nodes and 2cores per processor:</p>
<pre><code>qsub -I -l nodes=2:ppn=2
</code></pre>
<p>after starting R:</p>
<pre><code>library(doParallel)
f <- Sys.getenv('PBS_NODEFILE')
nodes <- unique(if (nzchar(f)) readLines(f) else 'localhost')
print(nodes)
</code></pre>
<p>here are the two nodes I"m running on:</p>
<pre><code>[1] "compute-3-15" "compute-1-32"
</code></pre>
<p>start the sock cluster on these two nodes:</p>
<pre><code>cl <- makePSOCKcluster(nodes, outfile='')
</code></pre>
<p>i'm not sure why they both seem to be on <code>compute-3-15</code> .... ?</p>
<pre><code>starting worker pid=25473 on compute-3-15.local:11708 at 16:54:17.048
starting worker pid=14746 on compute-3-15.local:11708 at 16:54:17.523
</code></pre>
<p>but register the two nodes and run a single foreach loop:</p>
<pre><code>registerDoParallel(cl)
r=foreach(i=seq(1,6),.combine='c') %dopar% { Sys.info()[['nodename']]}
print(r)
</code></pre>
<p>output of r indicates that both nodes were used though:</p>
<pre><code> [1] "compute-3-15.local" "compute-1-32.local" "compute-3-15.local"
[4] "compute-1-32.local" "compute-3-15.local" "compute-3-15.local"
</code></pre>
<p>now, what I'd really like is for that foreach loop to run on 4 cores, 2 on each node.</p>
<pre><code>library(doMC)
registerDoMC(4)
r=foreach(i=seq(1,6),.combine='c') %dopar% { Sys.info()[['nodename']]}
print(r)
</code></pre>
<p>the output indicates that only 1 node was used, but presumably both cores on that one node.</p>
<pre><code>[1] "compute-3-15.local" "compute-3-15.local" "compute-3-15.local"
[4] "compute-3-15.local" "compute-3-15.local" "compute-3-15.local"
</code></pre>
<p>How do I get a SINGLE foreach loop to use multiple cores on multiple nodes?</p>

React Native navigating between two screens back & forth
|
<p>I have <strong>Home</strong> screen where we search for an ItemCode, after we search ItemCode it will get details from API & screen will navigate to <strong>Screen 1</strong>(Item Details Screen) & from Screen 1 we have a search for ItemNutrients and after search it will get Nutrients & Navigate to <strong>Screen 2</strong> (Nutrients Screen)</p>
<p>In other words</p>
<p>Home -> Screen 1 (Item Details Screen) -> Screen 2 (Nutrients Screen)</p>
<p>After getting the necessary details from API from search for Item Details & Nutrients, User can navigate between Item Details & Nutrients back and forth..</p>
<p>I could navigate from <strong>Screen 1</strong> (item Details) to <strong>Screen2</strong> (Nutrients Screen) and swipe back to <strong>Screen 1</strong> (item Details) but how could I swipe forward to look at <strong>Screen 2</strong> (Nutrients Screen) again without searching for nutrients in <strong>Screen 1</strong> as I already have the data from API for Nutrients.</p>
<p>Any ideas on how to implement this ? this is basically navigate to <strong>Screen 1</strong> to <strong>Screen 2</strong> on search from Screen 1 or if <strong>Screen 2</strong> search is already done and we have data so swipe forward should navigate to <strong>Screen 2</strong>, I can have a button to navigate to <strong>Screen 2</strong>, the button on Screen 1 conditinally appears only when we have API data for Nutrients Screen and it will navigate to <strong>Screen 2</strong> on that button click, but i need swipe functionality as well to navigate forward</p>
<p>I have Home, Screen 1, Screen 2 in stackNavigator, is it alright or i could use any other navigators to achieve this.</p>
<p>I have researched how to do this and can't find it in the docs anywhere. Please let me know if I am missing it somewhere. Thanks!</p>

<p>I got it working below is the code:</p>
<pre><code> const nutrionScanClick = () => {
if (!isNutritionScanned) setisNutritionScanned(true);
else {
//Make a API call here for new data for the new scanned one's and then navigate
navigation.navigate("NutritionFacts");

Why isn't my custom animation working correctly?
|
<p>My custom @keyframes animation is not working the way it should. </p>
<p>There is no gap between <code>Block 1</code> and <code>Block 2</code> when rotating but there is a small gap between <code>Block 2</code> and <code>Block 3</code>, <code>Block 3</code> and <code>Block 4</code>, and, <code>Block 4</code> and <code>Block 1</code>.</p>
<p>I cant understand why there is a gap between the above listed block or why there is no block between Block 1 and Block 2. What should I do to remove the gaps, I want it to look like a box without the gaps.</p>

iTextSharp asp:DataGrid does not show up in PDF
|
<p>Converting a generated html page to pdf using iTextSharp, I cannot get the table created from the asp:DataGrid to show up in the PDF. The page's HTML output for the datagrid looks like this:</p>
<pre><code><p>Purchases:</p>
<table rules="all" id="dg_Purchase" style="font-size: smaller; border-collapse: collapse;" border="1" cellspacing="0">
<tbody><tr>
<td>Lot #</td>
<td>&nbsp;</td>
<td>Title</td>
<td align="right">Price</td>
<td align="right">Buyer's Premium</td>
<td align="right">Tax</td>
<td align="right">Sub Total</td>
</tr><tr>
<td>118</td>
<td><input id="dg_Purchase_ctl02_CheckBox1" name="dg_Purchase$ctl02$CheckBox1" type="checkbox"></td>
<td>Yih-Wen Kuo (1959, Taiwan)</td>
<td align="right">$1,900.00</td>
<td align="right">$332.50</td>
<td align="right">$0.00</td>
<td align="right">$2,232.50</td>
</tr><tr>
<td>119</td>
<td><input id="dg_Purchase_ctl03_CheckBox1" name="dg_Purchase$ctl03$CheckBox1" type="checkbox"></td>

<td align="right">$315.00</td>
<td align="right">$0.00</td>
<td align="right">$2,115.00</td>
</tr>
</tbody></table>
<p>Payments:</p>
<table rules="all" id="dg_Payment" style="font-size: smaller; border-collapse: collapse;" border="1" cellspacing="0">

<td style="width: 120px;">Payment Method</td>
<td>Date</td>
<td align="right">Amount&nbsp;&nbsp;</td>
</tr><tr>
<td>Total</td>
<td>&nbsp;</td>
<td align="right">$0.00</td>
</tr>
</tbody></table>
</code></pre>
<p>When the HTML page is viewed, the table looks exactly how it should. But when I generate the PDF, the table (or rather, everything within the table) is not shown. Only the border is visible, pretty much being just a 2 px straight line for each table.</p>
<p>So in my normal script, after the entire page has loaded, the very last thing I do is:</p>
<pre><code> StringWriter stringWriter = new StringWriter();
HtmlTextWriter writer = new HtmlTextWriter(stringWriter);
Render(writer);
</code></pre>
<p>The functions for iTextSharp are below:</p>
<pre><code>protected override void Render(HtmlTextWriter writer)
{
MemoryStream mem = new MemoryStream();
StreamWriter twr = new StreamWriter(mem);
HtmlTextWriter myWriter = new HtmlTextWriter(twr);
base.Render(myWriter);
myWriter.Flush();
myWriter.Dispose();
StreamReader strmRdr = new StreamReader(mem);
strmRdr.BaseStream.Position = 0;
string pageContent = strmRdr.ReadToEnd();
strmRdr.Dispose();
mem.Dispose();
writer.Write(pageContent);
CreatePDFDocument(pageContent);
}
public void CreatePDFDocument(string strHtml)
{
string strFileName = HttpContext.Current.Server.MapPath("test.pdf");
// step 1: creation of a document-object
Document document = new Document();
// step 2:
// we create a writer that listens to the document
PdfWriter.GetInstance(document, new FileStream(strFileName, FileMode.Create));
StringReader se = new StringReader(strHtml);
HTMLWorker obj = new HTMLWorker(document);
document.Open();
obj.Parse(se);
document.Close();
ShowPdf(strFileName);
}
public void ShowPdf(string strFileName)
{
Response.ClearContent();
Response.ClearHeaders();
Response.AddHeader("Content-Disposition", "inline;filename=" + strFileName);
Response.ContentType = "application/pdf";
Response.WriteFile(strFileName);
Response.Flush();
Response.Clear();
}
</code></pre>
<p>Again, everything on the page that is set programatically does show up in the PDF EXCEPT for the datagrid. Going off the borders, it appears that it is not a <code>width</code> issue. It just appears to be empty, is all. Any help would be greatly appreciated.</p>

mp.isPlaying() is throwing Fatal NullPointerException
|
<p>I have an application that plays sounds on button press.</p>
<p>I'm trying to force the MediaPlayer to mute on incoming call and to continue at normal volume afterwards (in idle mode).</p>
<p>I've wrote the below code to do exactly this, although it's crashing under NullPointerException on the following line.</p>
<pre><code>if (mp.isPlaying() && state == TelephonyManager.CALL_STATE_RINGING) {
</code></pre>
<p>Because of</p>
<pre><code>mp.isPlaying()
</code></pre>
<p>Can anyone identify why this is happening? Later on in my code I reference mp to play sounds.</p>
<pre><code> // Release any resources from previous MediaPlayer
if (mp != null) {
mp.release();
}
// Create a new MediaPlayer to play this sound
mp = MediaPlayer.create(this, resId);
mp.setLooping(true);
mp.start();
</code></pre>
<p><strong>This is my on call mute and on idle resume code.</strong></p>
<pre><code>protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
PhoneStateListener phoneStateListener = new PhoneStateListener() {
@Override
public void onCallStateChanged(int state, String incomingNumber) {
if (mp.isPlaying() && state == TelephonyManager.CALL_STATE_RINGING) {
mp.setVolume(0,0);
} else if(mp.isPlaying() && state == TelephonyManager.CALL_STATE_IDLE) {
mp.setVolume(1,1);
} else if(mp.isPlaying() && state == TelephonyManager.CALL_STATE_OFFHOOK) {
mp.setVolume(0,0);
}

}
};
TelephonyManager mgr = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);
if(mgr != null) {
mgr.listen(phoneStateListener, PhoneStateListener.LISTEN_CALL_STATE);
}

<p>I cannot understand why mp is Null if it's called later on in the application. If it's not playing will that return null? If so how would I get around this.</p>

Gradle: Using includeFlat to let project depend on local project
|
<p>I've got the following setup, with workspace being a normal directory containing my programs and Lib/App being Gradle projects created with the <code>gradle init</code> wizard.</p>
<pre><code>\-- workspace
+-- Lib
+-- settings.gradle
\-- lib
+-- src\main\java\com\msgprograms\lib
\-- Library.java
\-- build.gradle
\-- App
+-- settings.gradle
\-- app
+-- src\main\java\com\msgprograms\app
\-- App.java
\-- build.gradle
</code></pre>
<p>I'm now trying to get <code>App</code> to use <code>Lib</code> as a library, but after about two hours of research I still can't get it to do so. As I plan to use <code>Lib</code> in a number of other projects in the future, I don't want to make it a part of <code>App</code> in any form. It wouldn't make sense to do that for me and it makes it easier to find the library in my workspace this way. I've tried the solutions detailed <a href="https://stackoverflow.com/questions/36479097/gradle-local-project-dependency">here</a>, as they seemed the most promising, but to no avail.</p>
<p>Here are the build and settings files.</p>
<pre><code>//////////////////////
// App\app\build.gradle
plugins {
id 'application'
}
repositories {
mavenCentral()
}
dependencies {
testImplementation 'org.junit.jupiter:junit-jupiter:5.8.2'
implementation 'com.google.guava:guava:31.0.1-jre'
}
application {
mainClass = 'com.msgprograms.app.App'
}
tasks.named('test') {
useJUnitPlatform()
}
//////////////////////
// App\settings.gradle
rootProject.name = 'Appl'
include('app')
</code></pre>
<pre><code>//////////////////////
// Lib\lib\build.gradle
plugins {
id 'java-library'
}
repositories {
mavenCentral()
}
dependencies {
testImplementation 'org.junit.jupiter:junit-jupiter:5.8.2'
api 'org.apache.commons:commons-math3:3.6.1'
implementation 'com.google.guava:guava:31.0.1-jre'
}
tasks.named('test') {
useJUnitPlatform()
}
//////////////////////
// Lib\settings.gradle
rootProject.name = 'Libr'
include('lib')
</code></pre>
<p>...and here are the sources:</p>
<pre><code>// App\app\src\main\java\com\msgprograms\app\App.java
package com.msgprograms.app;
public class App {
public String getGreeting() {
return "Hello World!";
}
public static void main(String[] args) {
System.out.println(new App().getGreeting());
System.out.println(Library.someLibraryFunction());
}
}
</code></pre>
<pre><code>// Lib\lib\src\main\java\com\msgprograms\lib\Library.java
package com.msgprograms.lib;
public class Library {
public boolean someLibraryMethod() {
return true;
}
}
</code></pre>
<p>While adding <code>includeFlat 'Libr'</code> to<code>App\settings.gradle</code> seems like the thing to use, I cannot for the life of me figure out how to <code>import com.msgprograms.lib.Library</code> successfully. The relevant answer doesn't go into enough detail to be of use, the linked docs are not helping and the other answers to the post linked above aren't helpful either.</p>
<p>How do I let gradle projects depend on another local library-type project?</p>

Getting errors when trying to compile program using boost and ncurses libraries
|
<p>I have just started to write a server and client for an assignment but can't get my client code to compile. The server compiles just fine using just the boost library but in my client code I am using boost and ncurses. </p>
<p>I am using <code>g++ battleship_client.cc -lboost_system -lncurses</code> when trying to compile.</p>
<p>I have googled like crazy but I haven't found a solution. I should also note that I am on a mac and that I am using vscode. I have changed my includePath to look like this:</p>

Java - When updating JLabel's icon, the new icon is put behind the old icon
|
<p>What I am trying to do is create a gui that allows you to select an image, display the image, and then perfom actions on it for a school project. This is what happens on startup. <a href="https://i.stack.imgur.com/vuBNX.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/vuBNX.png" alt="enter image description here"></a> Perfect! However, when I update the icon, it puts the new icon behind it: <a href="https://i.stack.imgur.com/23tC6.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/23tC6.png" alt="enter image description here"></a></p>
<p>Here is the code I'm using on my Jlabel: </p>
<pre><code>ImageIcon imageIcon = new ImageIcon();
try {
imageIcon = new ImageIcon(ImageIO.read(new File("/Users/ryanauger/Repos/JavaGUI/GUI/Images/cameraIcon.png")));
} catch (IOException e2) {
// TODO Auto-generated catch block
imageIcon = new ImageIcon();
e2.printStackTrace();
}
JLabel lblNewLabel = new MyJLabel(imageIcon);
lblNewLabel.setBounds(0, 6, 600, 600);
frame.getContentPane().add(lblNewLabel);
JButton btnNewButton = new JButton("Pick Image File");
btnNewButton.addActionListener(new ActionListener() {

JFileChooser jfc;
jfc = new JFileChooser();
File f = new File(System.getProperty("user.dir"));
jfc.setCurrentDirectory(f);
jfc.setFileSelectionMode(JFileChooser.FILES_AND_DIRECTORIES);
jfc.showOpenDialog(btnNewButton);
File selFile = jfc.getSelectedFile();

} catch (IOException e1) {
// TODO Auto-generated catch block
System.out.println(selFile.getAbsolutePath());

}
}
});
</code></pre>
<p>I am brand new to java, so any help is appreciated. Thanks!</p>
<p>EDIT: Here is the code for MyJLabel: </p>
<pre><code>class MyJLabel extends JLabel
{
ImageIcon imageIcon;
public MyJLabel(ImageIcon icon)
{
super();
this.imageIcon = icon;
}
@Override

Disable Scroll in Relation to Overlay
|
<p>Goal:<br>
When you click on the picture a overlay should display and the scroll should not affect the user interface. </p>
<p>Problem:<br>
When the page is long and you disable the scroll the content of the page in relation to overlay will be moved towards to the right side. When you have many picture, it will not be very user-friendly.</p>
<p>I have tried the solution from this <a href="https://stackoverflow.com/questions/8701754/just-disable-scroll-not-hide-it">page</a> and this <a href="https://stackoverflow.com/questions/4770025/how-to-disable-scrolling-temporarily?rq=1">page</a>
but they doesn't work in relation to this source code below.</p>
<p>I also have tried this <a href="https://stackoverflow.com/questions/9280258/prevent-body-scrolling-but-allow-overlay-scrolling">page</a> but it did't work at all. This link as a proposal. <code>jsbin.com/poyejulijo/edit?html,output</code></p>
<p>I have tried different solution but I failed.</p>
<p>Info:<br>
*Using jQuery and Bootstrap v.3<br>
*The overlay with scroll should be working in relation to the latest version of IE, FF and Chrome. </p>

CGAL::Surface_mesh_parameterization: write the vertices to off in the original order
|
<p>I am trying to modify <code>CGAL-4.13/examples/Surface_mesh_parameterization/lscm.cpp</code> so that the order of the vertices in the resulting off file is the same as in the input file.</p>
<h2> Update: Example </h2>
<p>Take a file <code>input.off</code> with the following simple content:</p>
<pre><code>OFF
4 2 0
-0.9310345 0.4333333 0
-1 0.4333333 0
-0.9310345 0.5 0
-1 0.5 0
3 1 0 2
3 2 3 1
</code></pre>
<p>When I call the standard <code>lscm</code> from CGAL with</p>
<pre><code>/path/to/CGAL-4.13-build/examples/Surface_mesh_parameterization/lscm input.off
</code></pre>
<p>I obtain <code>coords.off</code> containing</p>
<pre><code>OFF
4 2 0
-1 0.5 0
-0.931034 0.5 0
-0.931034 0.433333 0
-1 0.433333 0
3 3 2 1
3 1 0 3
</code></pre>
<p>and <code>uvmap.off</code> with</p>
<pre><code>OFF
4 2 0
-0.0166567 0.982769 0
1 1 0
1.01666 0.0172311 0
0 0 0
3 3 2 1
3 1 0 3
</code></pre>
<p>The files <code>coords.off</code> and <code>uvmap.off</code> contain the vertices and their parameter pairs in the same order (which is <em>different</em> from that in <code>input.off</code>). Instead, I would like the parameters in <code>uvmap.off</code> to be in the order corresponding to <code>input.off</code>. In particular, I want <code>uvmap.off</code> to look like this:</p>
<pre><code>OFF
4 2 0
1.01666 0.0172311 0
0 0 0
1 1 0
-0.0166567 0.982769 0
3 1 0 2
3 2 3 1
</code></pre>
<p>Basically, this renders <code>coords.off</code> redundant, as I can use <code>input.off</code> in its role.</p>
<h2> Effort at a solution </h2>
<p>From what I understand, this might be possible to achieve by calling <code>output_uvmap_to_off(...)</code> with 6 parameters instead of 4 (both versions can be found in <code>CGAL-4.13/include/CGAL/Surface_mesh_parameterization/IO/File_off.h</code>). As one of these parameters is a <code>VertexIndexMap</code>, I should probably also use </p>
<pre><code>CGAL::Surface_mesh_parameterization::LSCM_parameterizer_3< TriangleMesh_, BorderParameterizer_, SolverTraits_ >::parameterize(...)
</code></pre>
<p>instead of</p>
<pre><code>CGAL::Surface_mesh_parameterization::parameterize(...)
</code></pre>
<p>used in the example.</p>
<p>Here is a minimal (not really working) example. It is derived from <code>lscm.cpp</code> but I threw away a lot of things to remain concise.</p>

<p>This does not compile, complaining about a required conversion on line 131 in File_off.h.</p>
<h2> Actual questions </h2>
<ul>
<li>Is <code>vimap</code> initialized correctly?</li>
<li>Is this the reasonable direction towards my goal of writing the vertices in the same order?</li>
<li>If yes, how do I pass the correct arguments to <code>output_uvmap_to_off(...)</code>? For instance, it asks for a <code>VertexContainer</code> and I provide a <code>Vertex_range</code> (hence the compilation error, I suppose). Shall I just collect the vertices as suggested <a href="https://stackoverflow.com/questions/48809669/how-to-get-the-vertices-and-the-faces-of-a-polygon-mesh-with-cgal">here</a> or <a href="https://stackoverflow.com/questions/39521720/cgal-read-vertices-and-triangles-from-mesh">here</a> or is there a more elegant way?</li>
<li>If no, what is the right course of action?</li>

Slow sql select with index on postgres
|
<p>I have a production database which is replicated to a another host using londist. The table looks like</p>
<pre><code># \d+ usermessage
Table "public.usermessage"
Column | Type | Modifiers | Description
-------------------+-------------------+-----------+-------------
id | bigint | not null |
subject | character varying | |
message | character varying | |
read | boolean | |
timestamp | bigint | |
owner | bigint | |
sender | bigint | |
recipient | bigint | |
dao_created | bigint | |
dao_updated | bigint | |
type | integer | |
replymessageid | character varying | |
originalmessageid | character varying | |
replied | boolean | |
mheader | boolean | |
mbody | boolean | |
Indexes:
"usermessage_pkey" PRIMARY KEY, btree (id)
"usermessage_owner_key" btree (owner)
"usermessage_recipient_key" btree (recipient)
"usermessage_timestamp_key" btree ("timestamp")
"usermessage_type_key" btree (type)
Has OIDs: no
</code></pre>
<p>If executed on the replicated database, the select is fast as expected, if executed on the production host it's horrible slow. To make things more strange, not all timestamps are slow, some of them are fast on both hosts. The filesystem and the storage behind the production host is fine and not under heavy usage. Any ideas?</p>

I have a view called Search and I want to bind it to SearchModelView.
View has one button and one textbox and looks:</p>
<p></p>
<pre><code><Grid HorizontalAlignment="Stretch" VerticalAlignment="Stretch" >
<ComboBox Height="23" HorizontalAlignment="Left" Margin="12,40,0,0" Name="comboBox1" VerticalAlignment="Top" Width="174" />
<Label Content="Client:" Height="28" HorizontalAlignment="Left" Margin="0,12,0,0" Name="label1" VerticalAlignment="Top" Width="71" />
<Label Content="Client Reference:" Height="28" HorizontalAlignment="Left" Margin="0,69,0,0" Name="label2" VerticalAlignment="Top" Width="117" />
<TextBox
x:Name="clientRefTxt"
Text="{Binding Path=ClientRef, ValidatesOnDataErrors=True, UpdateSourceTrigger=PropertyChanged}"
Height="23"
HorizontalAlignment="Left"
Margin="12,103,0,0"
VerticalAlignment="Top"
Width="174" />
<Button
Content="Search Debtors"
Height="23"
HorizontalAlignment="Left"
Margin="12,140,0,0"
Name="button1"
VerticalAlignment="Top"
Width="89"
Command="{Binding Path=SearchCommand}"/>
</Grid>
</code></pre>
<p></p>
<p>And I want it to bind to SearchViewModel:</p>
<p>namespace Master.ViewModel
{</p>
<pre><code>public class SearchViewModel:WorkspaceViewModel
{
RelayCommand _searchCommand;
readonly Search _search;
#region Search Properties
public string ClientRef
{
get { MessageBox.Show("GET CLIENTREF"); return _search.ClientRef; }
set
{
MessageBox.Show("SET CLIENTREF");
if (value == _search.ClientRef)
return;
_search.ClientRef = value;
base.OnPropertyChanged("ClientRef");
}
}
#endregion
public ICommand SearchCommand
{
get
{
MessageBox.Show("SEARCHCOMMAND");
if (_searchCommand == null)
{
_searchCommand = new RelayCommand(
param=> this.Search(),
param=> this.CanSearch
);
}
return _searchCommand;
}
}
public void Search()
{
MessageBox.Show("SEARCHING");
}
bool CanSearch
{
get { return true; }
}
}
</code></pre>
<p>}</p>
<p>I removed all the assemblies at the top but assume that they are all there. Also note that SearchViewModel is in a separate dll, not in the exe with the View.
Any help would be great or at least a pointer in the write direction, I have already read the msdn article on MVVM and that didnt help...I kinda need a better rundown on binding those too pieces.
Thanks in Advance.
P.S.
Some more details:
SearchViewModel belongs to Master.ViewModel
SearchView is part of GUI.View
I have and idea how the binded objects work, im not to sure on how to bind the view to the viewmodel</p>

List sort implementation
|
<p>Have some problems with my list and sorting feature. I create class Variation and Variations. I trade Variations class as collection list of my Variation to separate it. Now when i have create collection i would like to sort by Variation property position, hovever i get error. Can you help me out? Below all necessary information.</p>
<p>Variation class:</p>
<pre><code>Public Class Variation
Property ID As Integer
Property Name As String
Property Erstellungsdatum As Date
Property Position As SByte
Sub New()
End Sub
Sub New(id As Integer)
_ID = id
End Sub
Sub New(id As Integer, name As String)
_ID = id
_Name = name
End Sub
Sub New(name As String, position As Integer)
_Name = name
_Position = position
End Sub
Sub New(id As Integer, name As String, position As SByte)
_ID = id
_Name = name
_Position = position
End Sub
Sub New(id As Integer, name As String, erstellungsdatum As Date)
_ID = id
_Name = name
_Erstellungsdatum = erstellungsdatum
End Sub
End Class
</code></pre>
<p>class Variations:</p>
<pre><code>Public Class Variations
Implements IDisposable
Implements IComparer(Of Variation)
Public MyVariationsCollection As List(Of Variation)
Sub New()
MyVariationsCollection = New List(Of Variation)
End Sub
Public Function AddToCollection(ByVal variation As Variation) As Boolean
MyVariationsCollection.Add(variation)
Return True
End Function
Public Sub RemoveFromCollection(index As Integer)
If Not IsNothing(MyVariationsCollection.Item(index)) Then
MyVariationsCollection.RemoveAt(index)
End If
End Sub
Public Function Compare(x As Variation, y As Variation) As Integer Implements IComparer(Of Variation).Compare
If x.Position > y.Position Then
Return 1
End If
If x.Position < y.Position Then
Return -1
End If
Return 0
End Function
End Class
</code></pre>
<p>in the code i am doing:</p>
<pre><code>Private variations As New Variations
variations.AddToCollection(New BusinessLayer.Variation(Id, Name, StartPosition))
</code></pre>
<p>now i would like to sort this list by e.g Position which i implemented in Variations and i would like it to be there and not in Variation class as i want trade Variations class as collection of Variation object to separate if you know what i mean.</p>
<p>however if i do:</p>
<pre><code>_variations.MyVariationsCollection.Sort()
</code></pre>
<p>then i get error:</p>

jquery validate firing unhighlight function imediately after highlight
|
<p>despite my problem is similar <a href="https://stackoverflow.com/questions/22903707/jquery-validate-is-firing-both-highlight-and-unhighlight-in-chrome">with this</a></p>
<p>the proposed solution did not work for me.
Let me explain what happens.
As the title suggests unhiglight is called right after highlight.</p>
<p>and this happens only under one scenario only:
<strong>using remote method of email</strong>.
If the ajax call returns true(after hitting the submit button)(email does not exist) error class is added and immediately replaced by valid class in the fields that are not filled(required)...</p>
<p>if I hit submit again the problem does not appear...if some fields are not filled error class is attached properly.</p>
<p>What differentiates first from second submit(and if email is not changed) is the fact that ajax call for the email is not made.</p>
<p>So if ajax call is made(for the email) and returns true the above problem appears.
The code for the showerrors method found in the above Soverflow post does not help.</p>
<p><strong>I must emphasize that if I remove the remote method for the email the problem is fixed</strong></p>
<p>here is the code inside validate():</p>
<pre><code> $('#bizuserform').validate({
showErrors: function (errorMap, errorList) {
var errors = this.numberOfInvalids();
if (errors) {
var message = errors == 1 ? '1 field is miissing!!!' : errors + ' fields are missing!!!';
$("#error_general span").empty().html(message);
$("#error_general").show();
} else {
$("#error_general").hide();
}
this.defaultShowErrors();
},
highlight: function(element, errorClass, validClass) {

Execute non-query question with dataset results
|
<p>I have a fun project that involves VB.net winform app. This applications uses datasets for the forms. Three tables will be effected Shift_Log (SL), Problem_Log (PL) and Service_Request (SR). If the user changes the log dates on the (SL) so that the (PL) no longer agrees with the error time. I need to remove the foreign key from the (PL) and (SR) tables. I have not tested this yet. I have a couple of questions before I do.</p>
<ol>
<li><p>What if there are no records to update in the second update (SR)sql command?</p>
</li>
<li><p>do I need to refresh the Dataset after this is executed.</p>

Adding trend lines across groups and setting tick labels in a grouped violin plot or box plot
|
<p>I have <code>xy</code> grouped data that I'm plotting using <code>R</code>'s <code>ggplot2</code> <code>geom_violin</code> adding regression trend lines:</p>
<p>Here are the data:</p>
<pre><code>library(dplyr)
library(plotly)
library(ggplot2)
set.seed(1)
df <- data.frame(value = c(rnorm(500,8,1),rnorm(600,6,1.5),rnorm(400,4,0.5),rnorm(500,2,2),rnorm(400,4,1),rnorm(600,7,0.5),rnorm(500,3,1),rnorm(500,3,1),rnorm(500,3,1)),
age = c(rep("d3",500),rep("d8",600),rep("d24",400),rep("d3",500),rep("d8",400),rep("d24",600),rep("d3",500),rep("d8",500),rep("d24",500)),
group = c(rep("A",1500),rep("B",1500),rep("C",1500))) %>%
dplyr::mutate(time = as.integer(age)) %>%
dplyr::arrange(group,time) %>%
dplyr::mutate(group_age=paste0(group,"_",age))
df$group_age <- factor(df$group_age,levels=unique(df$group_age))
</code></pre>
<p>And my current plot:</p>
<pre><code>ggplot(df,aes(x=group_age,y=value,fill=age,color=age,alpha=0.5)) +
geom_violin() + geom_boxplot(width=0.1,aes(fill=age,color=age,middle=mean(value))) +
geom_smooth(data=df,mapping=aes(x=group_age,y=value,group=group),color="black",method='lm',size=1,se=T) + theme_minimal()
</code></pre>
<p><a href="https://i.stack.imgur.com/LrTt7.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/LrTt7.png" alt="enter image description here" /></a></p>
<p>My questions are:</p>
<ol>
<li>How do I get rid of the <code>alpha</code> part of the <code>legend</code>?</li>
<li>I would like the <code>x-axis</code> <code>ticks</code> to be <code>df$group</code> rather than <code>df$group_age</code>, which means a <code>tick</code> per each <code>group</code> at the center of that <code>group</code> where the label is <code>group</code>. Consider a situation where not all <code>group</code>s have all <code>age</code>s - for example, if a certain <code>group</code> has only two of the <code>age</code>s and I'm pretty sure <code>ggplot</code> will only present only these two <code>age</code>s, I'd like the <code>tick</code> to still be centered between their two <code>age</code>s.</li>
</ol>
<p>One more question:</p>
<p>It would also be nice to have the p-values of each fitted slope plotted on top of each <code>group</code>.</p>
<p>I tried:</p>
<pre><code>library(ggpmisc)
my.formula <- value ~ group_age
ggplot(df,aes(x=group_age,y=value,fill=age,color=age,alpha=0.5)) +
geom_violin() + geom_boxplot(width=0.1,aes(fill=age,color=age,middle=mean(value))) +
geom_smooth(data=df,mapping=aes(x=group_age,y=value,group=group),color="black",method='lm',size=1,se=T) + theme_minimal() +
stat_poly_eq(formula = my.formula,aes(label=stat(p.value.label)),parse=T)
</code></pre>
<p>But I get the same plot as above with the following <code>warning</code> message:</p>
<pre><code>Warning message:
Computation failed in `stat_poly_eq()`:
argument "x" is missing, with no default
</code></pre>

php mysql: Duplicate entry on production but not on dev
|
<p>Oke, i've been busting my head on this one.</p>
<p>I'm gonna try and keep things short, however, if you need more info, don't hesitate to ask.</p>
<p>I've written an import repo for an external firm, so we can import their data into our service.</p>
<h2>quick overview of implemented logic?</h2>
<p>ftp, grab xml file, parse it with simple_xml and do db stuff using laravel eloquent component.</p>
<p>on my dev machine,
every run gets parsed fully and all data is inserted correctly into the database.</p>
<h2>problem</h2>
<p>when i try the same thing on my production server.
I'm receiving a duplicate entry error, always on the same exact record. (unless i'm using another file)</p>
<h2>pre script setup to help detect the error</h2>
<p>on each run i do the following:</p>
<ul>
<li>make sure i'm using the exact same files on both dev and prod
environment... (i've disabled the ftpgrab and uploaded manually to
the correct location) </li>
<li>truncate all the related tables so i'm always
starting with empty! tables.</li>
<li>i've manually triple-zillion checked for duplicates in the xml, but they're not in there.... and the fact that
my dev machine parses the file correctly confirms this.</li>
</ul>
<h2>what i tried</h2>
<p>at this point, i've got no more clues as to how i'm supposed to debug this properly.</p>
<p>by now, i've checked so many things (most of them i can't even remember), all of which seemed pretty unrelated to me, but i had to try them.
those things include:</p>
<ul>
<li>automatic disconnects due to browser</li>
<li>mysql wait timeouts</li>
<li>php script timeouts</li>
<li>memory settings</li>
</ul>
<p>none of them seem to help (which was exactly what i was expecting)</p>
<h2>another fact</h2>
<p>my php version on my dev is 5.4.4 and the version on the production server is 5.3.2 (i know this is bad practise, but i'm not using any new features, it's really dead easy code, though it has quite a few lines :-) )</p>
<p>i've been suspecting this to be the cause, but</p>
<p>i've now switched to 5.3.14 on my dev... still the import runs without an issue</p>
<p>the changes from 5.3.2 to 5.3.14 are probably pretty minor</p>
<p>i've tried to manually compile the exact same php version, but i'm to inexperienced to properly do this. moreover, it probably wouldn't have the exact same specs anyway (i think it's pretty impossibly to ./configure exactly the same, considering the use of MacOs vs Ubuntu? especially for a noob like me)
So i've abandoned this path.</p>
<p>I've tried to find the differences in the php versions, but i can't seem to stumble upon anything that might be the cause to all this.
there was a change related to non-numeric keys in arrays (or strings for that matter) in version 5.4.4 (i think) but since i've now come to the conclusion that 5.3.14 also works, this definitely is not the issue. --- looking around insecurely hoping not having said anything downright stupid ---</p>
<h2>quick thought while writing this:</h2>
<p>the thing is, even though i'm getting the duplicate error statement.
The record did get inserted into the database.
moreover, the error gets triggered when having processed about 2700 (of total 6000) records.
the bound data to the query is actually the data of the second record in the xml file.)</p>
<p>I'm sincerely hoping anyone could put me on the right track for this issue :(
If you made it this far, but don't have a clue about what's going on, thx for reading and sticking to it.</p>
<p>If you might have clue, please enlighten me!</p>

Unnamed Pipes in UNIX child message doesn't get received by father while sending a string in C

<p>As you can see above, when I log out the stack where I've split by line, the output is completely different so I no longer have the data that I originally had when I first printed the console.</p>
<p>How can I parse this exception.stack and maintain the original the content that first logged at the start of the method.</p>

How to use the OnClickListener attribute for button by its ID in android java
|
<p>I am trying to achieve the same result by id for every button, using onClickListener.
This is the link to the original code where onClick is used for all buttons without creating id for reference.
The reason why I intended to create id for every button unlike in the original code is I felt the original code is kinda simplified but I thought to challenge myself to see if the same result can be achieved by using reference, though I know its complexity. But I am trying to do things differently and not just blindly copy-paste the code :)</p>
<p>Any help is highly appreciated!</p>
<p>p.s. Please consider code related to button code only as I am getting error in that part and I haven't yet gone any beyond in the original code.</p>

php cURL doesnt print out anything

<p>I am trying to send a HTML form POST data with a cURL, but it seems the response is always empty. I first save all the POST data in an array, and use an implode function. When I echo out the implode string it does return the values, but after the cURL it's just empty.</p>
<p>This is the setup. I call this function after submitting the form</p>
<pre><code>$this->OCIcURL($this->request->post);
public function OCIcURL($post) {
$data_oci = array();
$items_oci = array();

<p>If I echo out the <code>$string_oci</code> I do get a result. After this I use the cURL to send the string to a link.</p>

curl_setopt($ch, CURLOPT_POST, 1);

var_dump($response);

<p>The var_dump is always empty, returning <code>string(0) ""</code>. I also tried this on the live website, same result.</p>
<p>I used this piece of code to see any errors, but it seems it there arent any error at all, but the <code>var_dump</code> is always empty.</p>

<p>Is it possible from a backbone.js view to render an underscore.js template with a variable that is not defined in the related Backbone.js model?</p>
<p>take the <code>can't find variable: username</code> error.</p>
<p>the template to be rendered:</p>
<pre><code><div class="content" id="content">
<div id="form">
<form action="">
<input id="username" type="text" placeholder="Username" name="username" value= <%=username%> >
<input id="password" type="password" placeholder="Password" name="password" >
<ul class="table-view">
<li class="table-view-cell">
Remember me
<div class="toggle active">
<div class="toggle-handle"></div>
</div>
</li>
</ul>
<button id="logbtn" class="btn btn-primary btn-block">Login</button>
</form>
<button id="renregbtn" class="btn btn-positive btn-block">Register</button>
</div>
</div>
</code></pre>
<p>rendering line from the view:</p>
<pre><code>this.$el.html( this.template_login( this.loginModel ) );
</code></pre>
<p>line form the loginModel model file:</p>
<pre><code>define([
'underscore',
'backbone',
],
function(_, Backbone) {
var LoginModel = Backbone.Model.extend({
urlRoot: '/login',
initialize: function(){
this.fetch();
},
});
return LoginModel;
});
</code></pre>
<p>I set the model manually. But still take the can't find variable error as in the first render case.</p>
<p>same model above:</p>
<pre><code>define([
'underscore',
'backbone',
],
function(_, Backbone) {
var LoginModel = Backbone.Model.extend({
urlRoot: '/login',
defaults: {
username: "abc",
},
initialize: function(){
this.fetch();
},
});
return LoginModel;
});
</code></pre>
<p>Both cases result in:</p>
<pre><code>ReferenceError: Can't find variable: username
</code></pre>
<p>Only if I give an hardcoded model json into the template_login it works.</p>
<pre><code>this.$el.html( this.template_login( {username: "Joe"} ) );
</code></pre>

Video doesn't play first time on Android
|
<p>I have an Augmented Reality scene which downloads an AssetBundle containing a video. The video is set to Play on Awake so that it plays as soon as it is downloaded and instantiated. On iOS the all works perfectly, however on Android, the AssetBundle downloads and instantiates but only shows the white plane and doesn't play the video.
However, if you exit the scene or the App and try again, it works the second time as it's supposed to.</p>

How to Join Multiple Reference Tables Based on a String
|
<p>Suppose that I am given three sheets to pull data from and I need to get repeating data back from those sheets. Essentially for each user in a user group, find all the permissions associated from another group and display given permissions. My sheets are setup as such. <strong>(Assume top left is A1)</strong></p>
<h3>First Table (User Sheet)</h3>
<pre><code>Username Group
GPARR11 ACC-ADMIN
LPARR11 PRT-MGR
CSMITH VP-SALES
</code></pre>
<h3>Second Table (Permissions Sheet)</h3>
<pre><code>Group Ref Table Rows Switches
ACC-ADMIN 500 YNYNNNYN
ACC-ADMIN 502 YNYYY
ACC-ADMIN 503 NYNYYN
PRT-MGR 500 NNNYNNNYN

<h3>Final Table (Reference Sheet)</h3>
<p><em>This sheet get's it's reference from the third column in the second sheet. So if a character is <code>Y</code> then it has that permission enabled <code>N</code> then it doesn't.</em></p>
<pre><code>Ref Table Switch Row Sequenc # Permission
500 1 Access G&B
500 2 Access Call
500 3 Access A/R
633 1 Modify G&B
633 2 Modify Call
633 3 Modify Memos
999 1 Delete G&B
</code></pre>
<h3>What I'm expecting to see</h3>
<pre><code>Username Group Permission Enabled
GPARR11 ACC-ADMIN Access G&B TRUE
Access Call FALSE
Access A/R TRUE
LPARR11 PRT-MGR Access G&B FALSE
Access Call FALSE
Access A/R FALSE
Modify G&B TRUE
Modify Call FALSE
Modify Memos TRUE
CSMITH38 VP-SALES Access G&B FALSE
Access Call TRUE
Access A/R FALSE
</code></pre>
<h3>ADDT'L Info</h3>
<p>Essentially the way that the information is supposed to flow to get each of the expected outputs is as follows. For each Username match their group name with the group name in the second sheet. From there the <code>Ref Table Rows</code> would tell you which rows are allowed to be returned, mapping the <code>Switches</code> <code>(YNYNYN)</code> with the respective Ref Table Rows from the reference sheet. The sequence number is there to determine which permission matches with the respective Switch. 1 is first char, 2 the second char, etc.. and determines whether it returns true or false on the output.</p>
<p>Looking at <code>GPARR11</code> the <code>ACC-ADMIN</code> matches with <code>ACC-ADMIN</code> in the permissions table. There are three <code>Ref Table Rows</code> associated with <code>ACC-ADMIN</code>, <code>500</code>, <code>502</code>, <code>503</code>. Each row has <code>Switches</code> that correspond to the <code>Reference Table</code>. So it will pull ALL permissions from <code>500</code>, <code>502</code>, <code>503</code>, and then check the <code>switch</code> to determine if each permission from the <code>ref rows</code> is <code>TRUE</code> or <code>FALSE</code> </p>
<p>Is there a way that this can be done with a formula?</p>

<p>It appears to be a bug in craft related to the UrlManager code, but if this is the case, I don't know why others have not seemed to experience it (I couldn't find anything about it in my searches)? Does anyone have any suggestions as to what could be wrong?</p>

SemanticModel GetSymbolInfo().Symbol is Null in Constructed Code but not Parsed Code
|
<p>Given the following code</p>
<pre><code>var forText = "int i;for(i=0;i<3;i++){}";
</code></pre>
<p>I wish to grab a reference to the <code>i</code> in <code>i=0</code>, and then request its symbol info to see where it was declared, if anywhere! To do this using the string above, you would do the following</p>
<pre><code>var forText = "int i;for(i=0;i<3;i++){}";
var mscorlib = MetadataReference.CreateFromFile(typeof(object).Assembly.Location);
var options = CSharpParseOptions.Default.WithKind(SourceCodeKind.Script);
var goodTree = CSharpSyntaxTree.ParseText(forText, options);
var goodCompilation = CSharpCompilation.CreateScriptCompilation("GoodCompilation", syntaxTree: goodTree, references: new[] { mscorlib });
var goodModel = goodCompilation.GetSemanticModel(goodTree);
var goodLeft = goodTree.GetRoot().DescendantNodes().OfType<AssignmentExpressionSyntax>().First().Left;
var goodSymbol = goodModel.GetSymbolInfo(goodLeft).Symbol;
</code></pre>
<p>This works fine as expected, and <code>goodSymbol</code> is successfully assigned a value. However, in my program what I need to do is perform semantic analysis against an existing syntax tree. For some reason however, if the tree above is manually created via <code>SyntaxFactory</code> nodes, <code>GetSymbolInfo().Symbol</code> returns <code>null</code>!</p>
<pre><code>//using static Microsoft.CodeAnalysis.CSharp.SyntaxFactory;
var manualTree = CompilationUnit()
.WithMembers(
List(new MemberDeclarationSyntax[] {
GlobalStatement(
LocalDeclarationStatement(
VariableDeclaration(
PredefinedType(Token(SyntaxKind.IntKeyword)),
SingletonSeparatedList(
VariableDeclarator("i")
)
)
).NormalizeWhitespace()
),
GlobalStatement(
ForStatement(
null,
SingletonSeparatedList<ExpressionSyntax>(
AssignmentExpression(SyntaxKind.SimpleAssignmentExpression,
IdentifierName("i"),
LiteralExpression(SyntaxKind.NumericLiteralExpression, Literal(0))
)
),
BinaryExpression(
SyntaxKind.LessThanExpression,
IdentifierName("i"),
LiteralExpression(SyntaxKind.NumericLiteralExpression, Literal(3))
),
SingletonSeparatedList<ExpressionSyntax>(
PostfixUnaryExpression(SyntaxKind.PostIncrementExpression,
IdentifierName("i")
)
),
Block()
)
)}
));
var badTree = CSharpSyntaxTree.Create(manualTree, CSharpParseOptions.Default.WithKind(SourceCodeKind.Script));
var badCompilation = CSharpCompilation.CreateScriptCompilation("BadCompilation", syntaxTree: badTree, references: new[] { mscorlib });
var badModel = badCompilation.GetSemanticModel(badTree);
var badLeft = badTree.GetRoot().DescendantNodes().OfType<AssignmentExpressionSyntax>().First().Left;
var badSymbol = badModel.GetSymbolInfo(badLeft).Symbol;
</code></pre>
<p>The nodes and tokens in both trees appear to be exactly the same; there do not appear to be any nodes in the <code>goodTree</code> that are reused in multiple places (each <code>SyntaxNode</code> has a unique object reference) - there is simply something fundamentally different about the parsed tree to the constructed tree, but I have no idea what! Both trees have the exact same string representation, so there must be some kind of metadata on either the <code>SyntaxTree</code> or some of the <code>SyntaxNode</code> objects that makes this work in <em>good</em> but not <em>bad</em></p>

Remove Padding with SlideToogle

<p>I have some code that expands the rows. The table has padding for each td. Which is fine but the table when collapsed still shows this padding,</p>

Apply random value to animation-duration using jQuery
|
<p>I have a page that generates 20 randomly sized div elements and places them in random locations within a div container.
Using CSS @keyframe animations I can apply a very simple scale and color animation to each element.</p>
<p>I would like to set the animation-duration CSS property to a random number for each element. I tried to do so using the jQuery.css method like so;</p>
<p><code>element.css({ 'animation-duration': animationTime, 'animation-delay': animationTime });</code></p>
<p>but this does not work.</p>
<p>Any suggestions?</p>
<p>The full code is below - example is live at <a href="http://codepen.io/CronanGogarty/pen/ZOexMN" rel="nofollow">http://codepen.io/CronanGogarty/pen/ZOexMN</a></p>
<pre><code>.animationContainer {
width: 100%;
min-height: 400px;
height: 100%;
border: 1px solid #000;
overflow:hidden;
}
.animationElement {
position: absolute;
background-color: yellow;
animation: increase infinite;
animation-direction: alternate;
}
@keyframes increase {
0% {
border-radius: 100%;
}
50% {
background-color: orange;
}
100% {
transform: scale(2);
background-color: red;
}
}
$(function () {
createRandomElements();
});
function createRandomElements() {
for (var i = 0; i < 20; i++) {
var dimensions = Math.floor(Math.random() * (60 - 10) + 10);
var width = $('.animationContainer').width();
var height = $('.animationContainer').height();
var eltop = Math.floor(Math.random() * (height - dimensions) + dimensions);
var elleft = Math.floor(Math.random() * (width - dimensions) + dimensions);
var animationTime = Math.floor(Math.random() * (5 - 2 + 1)) + 2;
var element = $('<div>', {
class: 'animationElement',
width: dimensions,
height: dimensions
});
element.css({ 'animation-duration': animationTime, 'animation-delay': animationTime });
element.offset({ top: eltop, left: elleft });
$('.animationContainer').prepend(element);
}
}
</code></pre>
<p>As an additional question - can anyone explain why the <code>overflow:hidden</code> property isn't working on the .animationContainer element? I suspect it's because the .animationElement divs are being prepended to the container - if anyone has a solution I'd be very thankful.</p>

React: Build Connections Among Component
|
<p>I am a beginner of React JS. Messing around to achieve VanJS event listeners.</p>
<p>For layout, I decide to store things like <code>a panel, a button</code> as individual component.</p>
<p>Now, I have a component <code>Movie</code> and another component <code>Button</code>, how can I <b>trigger state change of Movie by Button.onclick()?</b>.</p>
<p>In other words, how to <b>modify a component by the event happening on another component?</b></p>
<p>Before posting, I have read:</p>
<ul>
<li><a href="https://www.youtube.com/watch?v=Oioo0IdoEls" rel="nofollow noreferrer">React Basics Component Lifecycle</a></li>
<li><a href="https://reactjs.org/docs/hooks-state.html" rel="nofollow noreferrer">Using the State Hook</a></li>
</ul>
<p>but tons of method followed by really confused me.</p>
<ul>
<li><code>useState</code></li>
<li><code>componentWillMount</code>: immediately before initial rendering</li>
<li><code>componentDidMount</code>: immediately after initial rendering</li>
<li><code>componentWillReceiveProps</code>: when component receives new props</li>
<li><code>shouldComponentUpdate</code>: before rendering, after receiving new props or state</li>
<li><code>componentWillUpdate</code>: before rendering, after receiving new props or state.</li>
<li><code>componentDidUpdate</code>: after component's updates are flushed to DOM</li>
<li><code>componentWillUnmount</code>: immediately before removing component from DOM</li>
</ul>
<p>Following is a demo, which contains a <code>Movie</code> card and a <code>Button</code>, when the button is clicked, I want <b>the background colour of the Movie card to change</b></p>

<p>However, when clicking on the change colour button, it doesn't work and shows a warning:</p>
<pre><code>Warning: Can't call setState on a component that is not yet mounted. This is a no-op, but it might indicate a bug in your application. Instead, assign to `this.state` directly or define a `state = {};` class property with the desired state in the Movie component.

<p>if anyone offers some suggestion, I will be so glad.</p>

Jquery is not working properly in asp.net AsyncPostBackTrigger
|
<p>net.</p>
<p>Recently I have tried to validate some asp controls with my jquery functions in the content page.</p>
<p>Below I have given some code where i want to validate one dropdown list which will check that
the selected Index of the dropdown list is 0. If it is zero then the background of the dropdown list
will be red. Else it will remain same.</p>
<p>The other Control is TextBox. In the same way if the textbox's length is 0 then the backround color will
be red.</p>
<p>When the save button will be clicked the validation will start.</p>
<p>Here I have given all the necessary code in jquery.</p>
<p>But the problem is when I click the Save Button then both Dropdown and Textbox turns red for a certain time(1 or 2 sec)
then turns into white background automatically. </p>
<pre><code> <asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">
<script>
$(document).ready(function () {
var valid = 0;
// check all fields validity when "Save" Button clicked
$("#<%= btnSave.ClientID%>").bind("click", function () {
var validity = validateAllFields();
if (validity == false) {
return false;
}
else {
}
});
});
/// validating all fields
// if all fields are valid then return true else return false//
function validateAllFields() {
var nValid = 0;
//validate DropDown box
nValid += checkDropdownList($("#<%= ddl1.ClientID%>")); // check ddl1 is Selected or not
//validate Text Field
nValid += checkTBLength($("#<%= tb1.ClientID%>"), 1); // check "tb1" length
if (nValid > 0) {
return false;
}
else {
return true;
}
}
// check whether the dropdownlist is selected other than "Select Item"
// parametes- idDropdown= id the of the dropdown List
function checkDropdownList(idDropdown) {
// check if the dropdown selected index is 0 or not
// if zero then set the background color red
if ($(idDropdown).prop('selectedIndex') == 0) {
$(idDropdown).css("background-color", "red").trigger("change"); // set dropdownlist background color to red
return 1;
}
else { // set the background color white
$(idDropdown).css("border-color", "");
return 0;
}
}
/// check minimum required length of the textbox
// Parameters- idTextbox= id of the textbox, minLength= minimum Required Length
function checkTBLength(idTextbox, minLength) {
//check if the textbox's lenth is less than minimum Required Length or not
if ($(idTextbox).val().length < minLength) {
$(idTextbox).css("background-color", "red"); // set the background textbox color to red
return 1; // return 1 for validation failed
}
else {

Binding MVC4 to An Object Containing Arrays
|
<p>I am creating a form to allow employees to submit timesheets online. The form consists of a number of sections, each representing a day of the week. Within each section, the user can add multiple rows, each row reflecting a task undertaken that day.</p>
<pre><code>function AddRow(day)
{
var count = $("#RowCount_" + day).data("count");
var row = "<tr>" +
"<td>&nbsp;</td>" +
"<td><input type='text' size='50' id='" + day + "[" + count + "].Description' name='timesheet." + day + "[" + count + "].Description' class='Description' data-day='" + day + "' /></td>" +
"<td><input type='text' size='6' id='" + day + "[" + count + "].Start' name='timesheet." + day + "[" + count + "].Start' /></td>" +
"<td><input type='text' size='6' id='" + day + "[" + count + "].Finish' name='timesheet." + day + "[" + count + "].Finish' /></td>" +
"<td><input type='text' size='6' id='" + day + "[" + count + "].Travel' name='timesheet." + day + "[" + count + "].Travel'/></td>" +
"<td>" +
"<select style='width:200px' id='" + day + "[" + count + "].JobNo' name='timesheet." + day + "[" + count + "].JobNo'>@Html.Raw(ViewBag.Jobs)</select>" +
"</td>" +
"<td><input type='text' size='6' id='" + day + "[" + count + "].Hrs' name='timesheet." + day + "[" + count + "].Hrs' /></td>" +
"</tr>";
$("#Table_" + day).append(row);
$("#RowCount_" + day).data("count", ++count);
}
</code></pre>
<p>I then want to bind this to a <code>Timesheet</code> object, as follows:</p>
<pre><code>public class Timesheet
{
List<Core.Models.TimesheetEntry> Monday = new List<TimesheetEntry>();
TimesheetEntry[] Tuesday { get; set; }
TimesheetEntry[] Wednesday { get; set; }
TimesheetEntry[] Thursday { get; set; }
TimesheetEntry[] Friday { get; set; }
TimesheetEntry[] Saturday { get; set; }
TimesheetEntry[] Sunday { get; set; }
}
</code></pre>
<p>(note I am trying both lists and arrays here, neither of which bind, but more of this in a minute)</p>
<p>The <code>TimesheetEntry</code> is as follows:</p>
<pre><code>public class TimesheetEntry
{
public string Description { get; set; }
public string Start { get; set; }
public string Finish { get; set; }
public decimal Travel { get; set; }
public string JobNo { get; set; }
public decimal Hrs { get; set; }
}
</code></pre>
<p>This posts to the following controller method:</p>
<pre><code>[HttpPost]
public ActionResult Create(Core.Models.Timesheet timesheet)
{
return View();
}
</code></pre>
<p>When submitted, the form does not bind (all fields in timesheet are 0 or null). However, if I change the controller to </p>
<pre><code>public ActionResult Create(List<Core.Models.TimesheetEntry> Monday)
{
return View();
}
</code></pre>
<p>and adjust the name of the html fields to <code>name='" + day + "[" + count + "].Description'</code> then it will bind just fine. This is a little messy, so I'd rather use the <code>Timesheet</code> class if possible. Is there an issue binding to Lists within models?</p>
<p>EDIT: Below is a snippet of the post data, with a single entry and 2 blank entries for monday, 3 blank for tuesday:</p>
<pre><code>timesheet.Monday[0].Description:test entry
timesheet.Monday[0].Start:0900
timesheet.Monday[0].Finish:1700
timesheet.Monday[0].Travel:0
timesheet.Monday[0].JobNo:14089A - line 14 hut heater sockets

line color change based on logic in apache echarts
|
<p><strong>Due to the company policy I can't share any kind of code</strong> but I have been struggling with apche echarts. The requirement is I have a line whose color should change at certain points based on logic. I tried achieving using linestyle and piecewise using dimension. I came pretty close to visualmap but the issue persisted when The parallel or adjacent lines started to get affected and caused wrong color changes on the graph. Here is the requirement the line on the chart is supposed to be red unless we come across a point where the color could be changed to green and back to red when the event is done. please refer to the image and I am open to any and all suggestions. I would prefer a sandbox as an answer link so i can test if that works with the requirement or not. <a href="https://i.stack.imgur.com/f3uxT.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/f3uxT.png" alt="requirement Image" /></a></p>

<p>I want to submit this registeration form with unique names.</p>
<p><strong>First Problem</strong> : I can't seem to map third time. The error shows <strong>array is not iterable</strong>.</p>
<p><strong>Second Problem</strong> : I cant change the setArray state in (<strong>array not empty</strong>) <strong>section</strong>. I know it is synchronous but I can't seem to find a solution.</p>
<p>Please give me a solution of if I want to have an immediate value of state after changing setState. I'm stuck in this problem for 3 days.</p>

Function to check if text is emoji dont recognize all the emojis
|
<p>I have a function that check if the string is emoji. the <code>function</code>:</p>
<pre><code>function has_emojis( $string ) {
preg_match( '/[\x{1F600}-\x{1F64F}]/u', $string, $matches_emo );
return !empty( $matches_emo[0] ) ? true : false;
}
</code></pre>
<p>the problem:
its not recognize all the emojis, for example its recgonize this one - as emoji but not this (and a lot of more)</p>
<p>I tried to change the preg_match range but without success because I dont know the specific range for all the emojis.</p>
<h2>Problem solution:</h2>
<p>use this function:</p>
<pre><code>function has_emojis( $string ) {
// Array of emoji (v12, 2019) unicodes from https://unicode.org/emoji/charts/emoji-list.html

Pattern matching case when
|
<p>I write simple math tokenizer and try to use new C# <code>pattern matching</code> feature.</p>
<p>Tokenizer is quite simple:</p>
<pre><code> public IEnumerable<IToken> Tokenize(string input)
{
const char decimalSeparator = '.';
string inputWithoutSpaces = input.Replace(" ", string.Empty);
var numberBuffer = new StringBuilder();
var letterBuffer = new StringBuilder();
foreach (char c in inputWithoutSpaces)
{
switch (c)
{
case var _ when IsTerm(c, letterBuffer):
if (numberBuffer.Length > 0)
{
yield return EmptyNumberBufferAsLiteral(numberBuffer);
yield return new Operator('*');
}
letterBuffer.Append(c);
break;
case decimalSeparator:
case var _ when IsDigit(c):
numberBuffer.Append(c);
break;
case var _ when IsOperator(c):
if (numberBuffer.Length > 0)
{
yield return EmptyNumberBufferAsLiteral(numberBuffer);
}
if (letterBuffer.Length > 0)
{
yield return EmptyLetterBufferAsTerm(letterBuffer);
}
yield return new Operator(c);
break;
}
}
if (numberBuffer.Length > 0)
{
yield return EmptyNumberBufferAsLiteral(numberBuffer);
}
if (letterBuffer.Length > 0)
{
yield return EmptyLetterBufferAsTerm(letterBuffer);
}
}
</code></pre>
<p>I'm using <code>case var _</code> because I want to match by condition without using <code>if-else if</code> chain, but I'm unable to write <code>case when</code> without specifying <code>var variableName</code>. </p>
<p>Is there any fancy way to perform such operation? Or it is recommended way to do these things?</p>

Java Websocket client lib issue: nv-websocket-client sendBinary
|
<p>When using sendBinary of this lib from client I got all 0 in the server ;(</p>
<p>this page asks me to to add more description but the code bellow is simple and straight forward and should be self explainable...</p>
<p>client side code:</p>

System.out.println("message from server: " + strmsg);
//echo back

System.out.println("now echo back with \"" + strmsg + "\"");
