SQL Xamarin Forms Delete Item Duplication
|
<p>I have an application where items are added to a collection view which is swipable to be deleted. I am using SQL to do so. However, when deleting the item, sometimes the items have 'duplicated' until a refresh happens and then they disappear once again. How do I go about fixing this issue and why does it only occur sometimes? (See below for bug).</p>
<p>Here is the Xaml:</p>
<pre><code><RefreshView x:DataType="local:ItemsViewModel" Command="{Binding LoadItemsCommand}" IsRefreshing="{Binding IsBusy, Mode=TwoWay}">
<CollectionView x:Name="ItemsListView"
ItemsSource="{Binding Items}"
SelectionMode="None">
<CollectionView.ItemTemplate>
<DataTemplate>
<SwipeView>
<SwipeView.RightItems>
<SwipeItems Mode="Execute">
<SwipeItem Text="Delete"
BackgroundColor="Red"
Command="{Binding Source={RelativeSource AncestorType={x:Type local:ItemsViewModel}}, Path=DeleteItemCommand}"
CommandParameter="{Binding Source={RelativeSource Self}, Path=BindingContext}"/>
</SwipeItems>
</SwipeView.RightItems>
<StackLayout Padding="10" x:DataType="model:Item" BackgroundColor="#333333">
<Label Text="{Binding Text}"
LineBreakMode="NoWrap"
Style="{DynamicResource ListItemTextStyle}"
FontSize="16"
FontAttributes="Bold"
TextColor="White"/>
<Label Text="{Binding Description}"
LineBreakMode="NoWrap"
Style="{DynamicResource ListItemDetailTextStyle}"
FontSize="13"
TextColor="White"/>
<Label Text="{Binding DueDate}"
Style="{DynamicResource ListItemDetailTextStyle}"
FontSize="13"
TextColor="White"/>
<StackLayout.GestureRecognizers>
<TapGestureRecognizer
NumberOfTapsRequired="1"
Command="{Binding Source={RelativeSource AncestorType={x:Type local:ItemsViewModel}}, Path=ItemTapped}"
CommandParameter="{Binding .}">
</TapGestureRecognizer>
</StackLayout.GestureRecognizers>
</StackLayout>
</SwipeView>
</DataTemplate>
</CollectionView.ItemTemplate>
</CollectionView>
</RefreshView>
</code></pre>
<p>Here is the delete function:</p>
<pre><code>private async Task OnDeleteItem(Item selectedItem)
{
await LocalDatabaseService.DeleteItem(selectedItem);
}
</code></pre>
<p>SQL Delete:</p>
<pre><code>public async Task DeleteItem(Item item)
{
var databasePath = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments), "MyData3.db");
var db = new SQLiteAsyncConnection(databasePath);
await db.DeleteAsync(item);
OnDeletedItem?.Invoke();
}
</code></pre>
<p>OnDeleteItem?.Invoke();</p>
<pre><code>private void LocalDatabaseService_OnDeletedItem()
{
_ = ExecuteLoadItemsCommand();
}
</code></pre>
<p>ExecuteLoadItemsCommand();</p>
<pre><code>async Task ExecuteLoadItemsCommand()
{
IsBusy = true;
try
{
Items.Clear();
var items = await LocalDatabaseService.GetAllItems();
foreach (var item in items)
{
Items.Add(item);
}
}
catch (Exception ex)
{
Debug.WriteLine(ex);
}
finally
{
IsBusy = false;
}
}
</code></pre>
<p>Here is what happens occasionally:

<p>any help is appreciated, Thanks.</p>

Azure devops timeout when downloading artifacts
|
<p>The release pipeline was working fine until recently, nothing had changed but it was saying that the agents were offline or disabled when they weren't. It turned out they needed to be updated from version <code>2.163</code> to <code>2.188</code> after this the pipeline would begin, but now it times out after downloading only a few artifacts.</p>
<p>What could be the issue?</p>
<p>EDIT:</p>
<p>The pre-releases <code>2.188.1</code> and <code>2.188.2</code> of the agents are allowing the pipeline to begin, but they timeout when downloading the artifacts. Anything before that version won't begin the pipeline. The last full release is <code>v2.187.2</code></p>
<p>EDIT 2:</p>
<p>I have noticed that during a change to the release pipeline it automatically updates this property in the defintion for every task.</p>
<p><code>"currentRelease": {"id": 3664,"url": "https://foo/bar/_apis/Release/releases/3664","_links": {}}</code></p>
<p>3664 is updated to a new number in both places</p>
<p>When I reverted this change, these properties are unchanged and keep that version and the release is still failing to start.</p>
<p>Logs when timing out:</p>

Relationship Between AffineTransformation and Polygon's Point
|
<p>As a project, I'm attempting to create an emulation of the game Asteroids. Currently, I'm trying to make it so then the spaceship appears on the opposite side of the GUI if the player ever sends himself out of bounds.</p>
<p>However, I've become quite confused between how AffineTransformation's rotate and createTransformedShape function interacts with the x and y points of the polygon. </p>
<p>Currently, I have the spaceship working; it flies in the angle the user specifies it and all the movement involved works fine. However, when I tried to get the lowest X coordinate of the spaceship to compare if it ever goes bigger than the constant <code>WIDTH</code>, it returns 780. This happens all the time whether or not I am on one side of the map to the other, it always returns 780. This I find really strange because shouldn't it return the smallest X coordinate of where it currently is?
<a href="https://i.stack.imgur.com/RA7rt.png" rel="nofollow noreferrer">Here is a screenshot of the console displaying that the "smallest x coordinate" of the polygon is 780, despite not being at 780</a></p>

Avoid new lines in csv because of carriage return with php
|
<p>doing my few first steps in PHP and I'm stuck. Been searching SO all afternoon but couldn't come up with a solution. Highly appreciate any advice from experienced devs.</p>
<p><strong>Scenario:</strong>
Users are asked to fill out a short survey consisting of two textareas. Upon hitting the submit button, the content of the textareas is written to a csv file.</p>
<p><strong>Problem:</strong>
My problem is that (while it does write the content) whenever people use carriage return in the textarea, it results in a new line in the csv file, thus messing it up. I've spent the afternoon reading up on stackoverflow and trying to use str_replace(); for rewriting all \n with spaces " ", alas to no avail.</p>
<p>Here is my <strong>HTML</strong>:</p>
<pre><code><!DOCTYPE html>
<html>
<head>
<title>Survey name here</title>
<meta charset='utf-8'>
</head>
<body>
<?php
if(!empty($errorMessage))
{
echo("<p>Error!</p>\n");
echo("<ul>" . $errorMessage . "</ul>\n");
}
?>
<div id="content">
<h1>Survey</h1>
<form action="post.php" method="post" id="survey">
<p><strong>Question 1:</strong><br />Do you like it or not?</p>
<p><textarea rows="6" cols="100" name="question1" value="<?=$answer;?>"><?php echo $answer ?></textarea></p>
<p><strong>Question 2:</strong><br />Would you prefer this or that?</p>
<p><textarea rows="6" cols="100" name="question2" value="<?=$answer2;?>"><?php echo $answer2 ?></textarea></p>
<input type="submit" name="formSubmit" value="Submit" id="submit" onclick="return Validate()"/>
</form>
</div><!-- End Content -->
</body>
</html>
</code></pre>
<p>And here is the <strong>PHP</strong> part:</p>
<pre><code><?php
if($_POST['formSubmit'] == "Submit")
{
$answer1 = $_POST['question1'];
$answer2 = $_POST['question2'];
// report error when not answered
$errorMessage = "";
if(empty($_POST['question1']))
{
$errorMessage .= "<li class='errormsg'>Please answer the question No. 1!</li>";
}
if(empty($_POST['question2']))
{
$errorMessage .= "<li class='errormsg'>Please answer the question No. 2!</li>";
}
// sending to CSV
if(empty($errorMessage))
{
str_replace('\r\n', ' ', $answer1 . $answer2);
$fs = fopen("test.csv","a");
fwrite($fs,$answer1 . ";" . $answer2 . "\n");
fclose($fs);
// after submit, head to thank you page
header("Location: thankyou.php");
exit;
}
}
?>
</code></pre>
<p>I figure I'm not applying the str_replace() function correctly. Who can help me?</p>

Script keep showing "SettingCopyWithWarning'
|
<p>Hello my problem is that my script keep showing below message </p>
<hr>
<p>SettingWithCopyWarning:
A value is trying to be set on a copy of a slice from a DataFrame</p>
<p>See the caveats in the documentation: <a href="https://pandas.pydata.org/pandas-docs/stable/user_guide/indexing.html#returning-a-view-versus-a-copy" rel="nofollow noreferrer">https://pandas.pydata.org/pandas-docs/stable/user_guide/indexing.html#returning-a-view-versus-a-copy</a>
downcast=downcast</p>
<hr>
<p>I Searched the google for a while regarding this, and it seems like my code is somehow
assigning sliced dataframe to new variable, which is problematic. </p>
<p>The problem is ** I can't find where my code get problematic **
I tried copy function, or seperated the nested functions, but it is not working </p>
<p>I attached my code below. </p>
<pre><code>def case_sorting(file_get, col_get, methods_get, operator_get, value_get):
ops = {">": gt, "<": lt}
col_get = str(col_get)
value_get = int(value_get)
if methods_get is "|x|":
new_file = file_get[ops[operator_get](file_get[col_get], value_get)]
else:
new_file = file_get[ops[operator_get](file_get[col_get], np.percentile(file_get[col_get], value_get))]
return new_file
</code></pre>
<p>Basically what i was about to do was to make flask api that gets excel file as an input, and returns the csv file with some filtering. So I defined some functions first. </p>
<pre><code>def get_brandlist(df_input, brand_input):
if brand_input == "default":
final_list = (pd.unique(df_input["브랜드"])).tolist()
else:
final_list = brand_input.split("/")
if '브랜드' in final_list:
final_list.remove('브랜드')
final_list = [x for x in final_list if str(x) != 'nan']
return final_list
</code></pre>
<p>Then I defined the main function </p>
<pre><code>def select_bestitem(df_data, brand_name, col_name, methods, operator, value):
# // 2-1 // to remove unnecessary rows and columns with na values
df_data = df_data.dropna(axis=0 & 1, how='all')
df_data.fillna(method='pad', inplace=True)
# // 2-2 // iterate over all rows to find which row contains brand value
default_number = 0
for row in df_data.itertuples():
if '브랜드' in row:
df_data.columns = df_data.iloc[default_number, :]
break
else:
default_number = default_number + 1
# // 2-3 // create the list contains all the target brand names
brand_list = get_brandlist(df_input=df_data, brand_input=brand_name)
# // 2-4 // subset the target brand into another dataframe
df_data_refined = df_data[df_data.iloc[:, 1].isin(brand_list)]
# // 2-5 // split the dataframe based on the "brand name", and apply the input condition
df_per_brand = {}
df_per_brand_modified = {}
for brand_each in brand_list:
df_per_brand[brand_each] = df_data_refined[df_data_refined['브랜드'] == brand_each]
file = df_per_brand[brand_each].copy()
df_per_brand_modified[brand_each] = case_sorting(file_get=file, col_get=col_name, methods_get=methods,
operator_get=operator, value_get=value)
# // 2-6 // merge all the remaining dataframe
df_merged = pd.DataFrame()
for brand_each in brand_list:
df_merged = df_merged.append(df_per_brand_modified[brand_each], ignore_index=True)
final_df = df_merged.to_csv(index=False, sep=',', encoding='utf-8')
return final_df
</code></pre>
<p>And I am gonna import this function in my app.py later </p>
<p>I am quite new to all the coding, therefore really really sorry if my code is quite hard to understand, but I just really wanted to get rid of this annoying warning message. Thanks for help in advance :) </p>

How to add more nodes in the self signed certificate of Kubernetes Dashboard
|
<p>I finally managed to resolve my question related to how to add more nodes in the CAs of the Master nodes (<a href="https://stackoverflow.com/questions/65186710/how-to-add-extra-nodes-to-the-certificate-authority-data-from-a-self-signed-k8s/65198463?noredirect=1#comment115265632_65198463">How to add extra nodes to the certificate-authority-data from a self signed k8s cluster?</a>).</p>
<p>Now the problem that I am facing is I want to use kubeconfig file e.g. <code>~/.kube/config</code> to access the Dashboard.</p>
<p>I managed to figured it out by having the following syntax:</p>
<pre class="lang-sh prettyprint-override"><code>$ kubectl config view
apiVersion: v1
clusters:
- cluster:
certificate-authority-data: DATA+OMITTED
server: https://IP:6443

current-context: kubernetes-admin@kubernetes
kind: Config
preferences: {}
users:
- name: kubernetes-admin
user:
client-certificate-data: REDACTED
client-key-data: REDACTED
token: REDACTED
</code></pre>
<p>The problem that I am having is that I need to use the IP of one of the Master nodes in order to be able to reach the Dashboard. I would like to be able to use the LB IP to reach the Dashboard.</p>
<p>I assume this is related to the same problem that I had before as I can see from the file that the CAs are autogenerated.</p>
<pre class="lang-sh prettyprint-override"><code>args:
- --auto-generate-certificates
- etc etc
.
.
.
</code></pre>
<p>Apart from creating the CAs on your self in order to use them is there any option to pass e.g. IP1 / IP2 etc etc in a flag within the file?</p>
<p><strong>Update:</strong> I am deploying the Dashboard through the recommended way <code>kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.0.0/aio/deploy/recommended.yaml</code> (<a href="https://kubernetes.io/docs/tasks/access-application-cluster/web-ui-dashboard/" rel="nofollow noreferrer">Deploying the Dashboard UI</a>). The deployment is on prem but I have configured the cluster with an external loadbalancer (HAProxy) towards the Api and also Ingress and also <code>type: LoadBalancer</code> on Ingress. Everything seems to working as expected apart from the Dashboard UI (through LB IP). I am also using authentication mode <code>authorization-mode: Node,RBAC</code> on the kubeconfig file (if relevant).</p>
<p>I am access the Dashboard through Inress HTTPS e.g. <code>https://dashboard.example.com</code>.</p>
<p>I get the error <code>Not enough data to create auth info structure</code>. Found the <code>token: xxx</code> solution from this question <a href="https://stackoverflow.com/questions/48228534/kubernetes-dashboard-access-using-config-file-not-enough-data-to-create-auth-inf">Kubernetes Dashboard access using config file Not enough data to create auth info structure.</a>.</p>
<p>If I switch the LB IP with the Master nodes then I can access the UI with the kubeconfig file.</p>
<p>I just updated now to the latest version of the dashboard v2.0.5 is not working with the kubeconfig button / file but it works with the token directly <a href="https://github.com/kubernetes/dashboard/releases/tag/v2.0.5" rel="nofollow noreferrer">kubernetes/Dashoboard-v2.0.5</a>. With the previous version everything works as described above. No error logs in the pod logs.</p>

pass coordinates from googlemaps react child to parent in functional component typescript
|
<p>I'm using @googlemaps/react-wrapper to make a map component in my react application using the example from <a href="https://developers.google.com/maps/documentation/javascript/react-map" rel="nofollow noreferrer">googlemaps</a>, and adding an event on drag marker to refresh coordinates, this works fine now. but i need to call the map component outside to refresh a input value with the coordiantes.
The error i get it is:</p>
<blockquote>
<p>Binding element 'childToParent' implicitly has an 'any' type.*
Please could help me to understand how i could send the values to paren using typescript
Greetings
In parent i have this</p>

SFSafariViewController : Overlay is not appearing sometimes
|
<p>I am using SFSafariViewController, and as i did not wanted to show the status bar of safari and i have hidden it by adding a overlay. I have my own button on the overlay and its working fine. The safari status bar is hidden and it shows my overlay but somehow sometimes the overlay disappears and the safari status bar is visible. I doubt that its because the link is being reloaded automatically but how? I am only calling it once. I am not sure why overlay is disappear for sometimes only. below is my code - </p>
<pre><code>self.navigationController?.presentViewController(sfController!, animated: true, completion: {
let bounds = UIScreen.mainScreen().bounds
let overlay = UIView(frame: CGRect(x: 0, y: 0, width: bounds.size.width, height: 65))
overlay.backgroundColor = UIColor(netHex: 0x275E37)
let completedBtn = UIButton()
let favBtn = UIButton()
let image = UIImage(named: "home.png") as UIImage?
let homeBtn = UIButton(type: UIButtonType.Custom) as UIButton
homeBtn.frame = CGRectMake(20, 25, 35, 35)
homeBtn.setImage(image, forState: .Normal)
homeBtn.addTarget(self, action: #selector(DetailsViewController.HomeBtnAction), forControlEvents:.TouchUpInside)
completedBtn.setTitle("Mark as Completed",forState: .Normal)
completedBtn.titleLabel!.font = UIFont(name: "FidelitySans-Regular", size: 20)
completedBtn.setTitleColor(UIColor.whiteColor(), forState: .Normal)

Node.js promise and for loop. Wait for async function inside a loop
|
<p>I'm pretty new to Node and also to JS. I already read a lot here at stackoverflow and I think I personally have one in my brain for the last view days trying to fix this issue ;-).</p>
<p>The purpose of this code is to get the steam name for each player from steam API and put it into json object. after that the json object is using to present the steam data on a web page.</p>
<p>I got everithing working, but the first time the web page is loading it is empty. The second time which page is loading there are all data available.</p>
<p>The steam user ID is held in a simple array. This array is put to a forEach method and inside this method the steam API is called to return each player name. This player names are returned into the final json object, which held both, the steam id and the steam name.</p>
<pre><code>input = steam ID's from array
process = get steam name from steam ID
output = json object with all steam ID's and names.
</code></pre>
<p>Important thing is, that the page has to wait for the API calls to finish.</p>
<p>I have the following code:</p>
<pre class="lang-js prettyprint-override"><code>var cfg = require('config');
var Promise = require('bluebird');
//access steam API for steamId resolution
var Steam = require('steam-webapi');
// Set global Steam API Key
Steam.key = cfg.get('steam.api.key');
// Create a file called STEAM_KEY and stick your API key in it
// (or insert it here)
var steamAPIKey = Steam.key;
if (steamAPIKey.length === 0) {
try { steamAPIKey = fs.readFileSync('../STEAM_KEY').toString();}
catch(e) {
try { steamAPIKey = fs.readFileSync('./STEAM_KEY').toString(); }
catch(e) { console.log('No API key provided'); }
}
}
var steamconnect = function() {
return new Promise(function (resolve, reject) {
Steam.ready(steamAPIKey, function (err, data) {
if (err) return console.log(err);
else {
var steam = new Steam({key: steamAPIKey});
resolve(steam);
}
});
});
};
var getsteaminfoforeach = function(arrsid, steam){
return new Promise(function(resolve, reject){
dataarr = [];
var i = 0;
arrsid.forEach(function(entry, callback) {
if (entry !== "") {
getsteaminfo(steam, entry)
.then(function(playername) {
console.log(playername);
dataarr.push({"name": playername, "id": entry});
resolve(dataarr);
});
}
});
});
};
var getsteaminfo = function(steam, entry) {
return new Promise(function (resolve, reject) {
Promise.promisifyAll(Steam.prototype); // Creates an promise wielding function for every method (with Async attached at the end)
steam.getPlayerSummariesAsync({steamids: entry})
.then(function (data) {
playername = data.players[0]["personaname"]; //extract user name from steam user object
//dataarr.push({"name": playername, "id": entry});
console.log("get steam user: " + "name: "+playername+ " id: "+ entry);
resolve(playername);
});
});
};
var donext = function() {
return new Promise(function (resolve, reject) {
console.log("do next: "+dataarr);
});
};
arrsid = ["765611980504","765611970371",""];
steamconnect()
.then(function(steam){
console.log("arrsid: "+arrsid);
getsteaminfoforeach(arrsid, steam)
.then(function (dataarr) {
console.log("Player name: " + dataarr);
donext()
});
});
</code></pre>
<p>This is the output:</p>
<pre><code>arrsid: 765611980504,765611970371,
get steam user: name: steamname1 id: 765611980504
steamname1
Player name: [object Object]
do next: [object Object]
get steam user: name: steamname2 id: 765611970371
steamname2
</code></pre>
<p>My issue is, that steamname... should be the first output (for each steamname) and after that do next: [] has to be called.</p>
<p>I'm sure there is a simple solution. Thank you very much! </p>

Nginx Ingress on Kubernetes Cluster
|
<p>`I had a working Ingress controller version 1.0.0 (Bitnami). It stopped working one fine morning, and it appeared that the error was due to the version being depricated. Now I tried to upgrade this version, but started getting errors. I delete ingress and reinstalled it again, and this time from Bitnami repo which pulled the latest image. It is throwing errors. I created a new AKS cluster and installed ingress on it from the same repo, and it seems to work perfectly fine. Can somebody help me understand how this can be fixed please? I have over 120 services running on this cluster, and starting over would mean a lot of effort and time.</p>

VideoTexture Crashes iPad
|
<p>I'm running a video texture in Away3d in an Adobe Air app which runs fine on desktop and Android, however on iOS it crashes as soon as it tests for VideoTexture support</p>
<p>I create the video as such</p>
<pre><code> sphereGeometry = new SphereGeometry(5000, 64, 48);
panoTexture2DBase = new NativeVideoTexture(Model.config.getAssetUrl(Model.currentScene.video), true, true);
panoTexture2DBase.addEventListener(NativeVideoTexture.VIDEO_START,function(e:Event =null){setTimeout(onVideoStart,1000)});
panoTextureMaterial = new TextureMaterial(panoTexture2DBase, false, false, false);
panoVideoMesh = new Mesh(sphereGeometry, panoTextureMaterial);
panoVideoMesh.scaleX *= -1;
panoVideoMesh.rotate(Vector3D.Y_AXIS,-90);
scene.addChild(panoVideoMesh);
view.render();
panoTexture2DBase.player.pause();
</code></pre>
<p>And the iPad appears to crash as soon as it plays</p>
<pre><code> _player.play();
</code></pre>
<p>In NativeVideoClass</p>
<p>Does anyone know how to stop the iPad crashing when I try and use VideoTexture or is this doomed to failiure? </p>
<p>This is the Air 21. </p>
<p>I've tried taking the video out of Away3d and into Starling. I've changed the codecs and managed to get it running in Starling. </p>
<p>The same video is still crashing in Away3D tho. It's when it's gets added to the stage. </p>
<p>I'm also getting NetStream.Play.Failed in the netstats event before it fails.</p>
<p>The crash report </p>

How to Avoid very long time python calculations while iterating through pandas dataframe
|
<p>I am trying to add 2 columns to dataframe to calculate vehicle surroundings neighbor 50 and neighbor 100 for each vehicle in each direction and in each time frame based on distance, if distance below 50 I add one count to the neighbor 50 and so on, I should do this task using Pandas only</p>
<p>I should calculate distance based on x and y position of each vehicle through the equation:</p>
<p>distance = ((x2 - x1)**2 + (y2 - y1)**2)**0.5</p>
<p>I have used this code:</p>
<pre><code>#import numpy as np
df['neighbor_50'] = 0
df['neighbor_100'] = 0
frame_group = df.groupby(['frame','direction'])
list_keys = list(frame_group.indices.keys())
for key in list_keys :
frame , direction = key[0] , key[1]
#new_df = df.loc[(df['frame'] == frame) & (df['direction'] == direction)]
mask1 = (df['frame'] == frame) & (df['direction'] == direction)
ids = df[mask1]['id']
for i in ids:
for j in ids:
if i != j:
#distance = sqrt((x2-x1)**2 + (y2-y1)**2)
maski = (df['frame'] == frame) & (df['direction'] == direction)& (df['id'] == i)
maskj = (df['frame'] == frame) & (df['direction'] == direction)& (df['id'] == j)
x2 = df[maski]['x'].iloc[0]
x1 = df[maskj]['x'].iloc[0]
y2 = df[maski]['y'].iloc[0]
y1 = df[maskj]['y'].iloc[0]
distance = ((x2 - x1)**2 + (y2 - y1)**2)**0.5
#distance = np.hypot((x2 - x1),(y2 - y1))
mask = (df['frame'] == frame) & (df['direction'] == direction) &( df['id']== i)
if distance <= 50:
df.loc[mask , 'neighbor_50'] += 1
if distance <= 100 :
df.loc[mask ,'neighbor_100'] += 1
</code></pre>
<p>the problem is that it takes forever to complete because the data is big even when i use NumPy.</p>
<p>input sample
<a href="https://i.stack.imgur.com/bYF7m.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/bYF7m.png" alt="input sample" /></a></p>

<a href="https://i.stack.imgur.com/7tmKP.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/7tmKP.png" alt="enter image description here" /></a></p>
<p>update:
I have managed to reduce the time by half by avoiding repeating calculations for same ids , but still so slow</p>
<pre><code>import numpy as np
df['neighbor_50'] = 0
df['neighbor_100'] = 0
frame_group = df.groupby(['frame','direction'])
list_keys = list(frame_group.indices.keys())

frame , direction = key[0] , key[1]
#new_df = df.loc[(df['frame'] == frame) & (df['direction'] == direction)]
mask = (df['frame'] == frame) & (df['direction'] == direction)
ids = df[mask]['id'].values
for i in range(len(ids)-1):
id1 = ids[i]
for j in range(i+1,len(ids)):
id2 = ids[j]

Project.exe has triggered a breakpoint (C)
|
<p>I'm a beginner programmer, I got a home assignment to seperate a string into words, and put each word in an array of strings. We are practicing dynamic memory allocations. the assignment says that the size of the array must be [10] and i need to change the size of the array with malloc accoring to the number of words in the string, and allocate room for every word in the array. when i reach the end of the programm and free the allocated memory it says "Project.exe has triggered a breakpoint" and i can't find my mistake in the code.</p>

Post Rocket route is forwarded (Rust)
|
<p>Sorry to ask such a basic question, there's little info about this in Stack Overflow and GitHub. This must be something silly, but I'm not getting it.</p>
<p>I'm trying to send via JavaScript's <code>fetch</code> to a Rust post endpoint with Rocket 0.5 RC1. But I'm getting hit by:</p>
<blockquote>
<p>No matching routes for POST /api/favorites application/json.</p>
</blockquote>
<p>Here's the complete log:</p>
<pre><code> POST /api/favorites application/json:
Matched: (post_favorites) POST /api/favorites
`Form < FavoriteInput >` data guard is forwarding.
Outcome: Forward

React Bootstrap button not recognising function onClick
|
<p>I have a React Bootstrap app with onclick Buttons. The first 2 buttons, play and pause work. The next buttons however do not even show in the react console as having an attached function prop.</p>
<p>All buttons link to functions within the same scope and they are all near identical.</p>
<p>I've tried changing the onClick calls and reducing the unrecognised functions to <code>console.log</code>s in case it was a function breaking them.</p>
<pre><code>class Buttons extends React.Component{
handleSelect =(e) => {
this.props.gridSize(e);
}
render(){
return(
<div className="buttonsDiv">
<ButtonToolbar>
<button className="btn" onClick={this.props.playButton}>Play</button>
<button className="btn" onClick={this.props.pauseButton}>Pause</button>
<button className="btn" onClick={this.props.clear}>Clear</button>
<button className="btn" onClick={this.props.fast}>Fast</button>
<button className="btn" onClick={this.props.slow}>Slow</button>
<button className="btn" onClick={this.props.seed}>Seed</button>

<Dropdown.Item eventKey="2">50x30</Dropdown.Item>
<Dropdown.Item eventKey="3">70x50</Dropdown.Item>
</DropdownButton>
</ButtonToolbar>
</div>
)
}
}
class Main extends React.Component {
constructor() {
super();
this.speed = 1100;
this.rows = 30;
this.cols = 50;
this.state = {
generation: 0,
gridFull: Array(this.rows)
.fill()
.map(() => Array(this.cols).fill(false)) //make array of Rows and foreach row make an array of all the columns - making a grid.
};
}
selectBox = (row, col) =>{
this.setState((previousState)=>{
let {gridFull} = previousState;
gridFull[row][col] = !gridFull[row][col]
return {gridFull: gridFull }
});
}
seed = () => {
this.setState((prevState)=> {
let {gridFull} = prevState;
for (let i=0; i<this.rows; i++){
for (let j=0; j< this.cols; j++){
if(Math.floor(Math.random() * 4) === 1){
gridFull[i][j] = true;
}
}
}
return {gridFull:gridFull}
});
}
playButton =() => {
clearInterval(this.intervalId)
this.intervalId = setInterval(this.play, this.speed);
}
pauseButton =() => {
clearInterval(this.intervalId);
}
slow =() => {
console.log('hi')
// this.speed=100;
// this.playButton();
}
fast = () => {
console.log(this.speed)
this.speed =1000;
this.playButton();
}
clear = () => {
var grid = Array(this.rows).fill().map(() =>
Array(this.cols).fill(false));
this.setState({
gridFull: grid,
generation : 0
});
}
play = () => {
code
}
componentDidMount(){
this.playButton();
this.seed();
}
render() {
return (
<div>
<h1>React Application</h1>
<Buttons playButton ={this.playButton}
pauseButton={this.pauseButton}
/>
<Grid
gridFull={this.state.gridFull}
rows={this.rows}
selectBox={this.selectBox}
cols={this.cols}
/>
<h2>Generations: {this.state.generation}</h2>
</div>
);
}
}
</code></pre>
<p>So in the buttons toolbar the first 2 buttons work and the rest do not even show functions as props in the react console.</p>
<p>As you can see they both call functions within the same scope, so I don't know what's happening.</p>

<p>I tried several manipulations : remove my node_modules and package-lock.json and re-install the application. I tried a newer version of accordion too and no solution worked for me.</p>
<p>Any Idea ?</p>

BrowserSync refreshing before injection (Gulp)

</code></pre>
<p>Mostly everything with my build works great, however I am having one issue with my compileHTML task. When any modifications are made to my html, it is compiled and injected into the page with BrowserSync. The problem is that BrowserSync is injecting the markup into the page AFTER it reloads, so that I have to manually refresh or save the file again.</p>
<p>Although I am doing the exact same thing with my SASS task, I have no problems with that task. Why do my styles inject into the page before the reload, but the HTML does not?</p>
<p>Just for testing, I tried adding a setTimout surrounding the BrowserSync injection, but it did not affect the timing of the injection other than adding a delay.</p>

Why does Play port not get started with library subproject?
|
<p>In <code>build.sbt</code> I have the lines like:</p>
<pre><code>lazy val sparkCommon = (project in file("spark-common"))//.enablePlugins(PlayScala)
lazy val root = (project in file(".")).enablePlugins(PlayScala)
.dependsOn(sparkCommon).aggregate(sparkCommon)
</code></pre>
<p>In <code>spark-common</code> project I have code in <code>src/main/scala/SimpleApp.scala</code>:</p>
<pre><code> object SimpleApp {
def getStr = "{ name = 'adf'}"
}
</code></pre>
<p>In my Spark project <code>root</code> I am trying to use that code.</p>
<p>With the <code>build.sbt</code> file above port listening is not started and I cannot access my service (but it compiles projects successfully, can make both packages and publish them to repo).</p>
<p>If I uncomment line <code>enablePlugins(PlayScala)</code> for my library <code>spark-common</code> project in the <code>build.sbt</code> file, it does not see <code>SimpleApp</code> (as I understand Play projects have a bit different structure, thus compilation error is reasonable, as code located under <code>/spark-common/src/main/scala/SimleApp.scala</code>).</p>
<p>It seems that I follow <a href="https://groups.google.com/forum/#!searchin/play-framework/2.3$20playscala$20/play-framework/lnEcyiPewn0/z49BVJD1Z60J" rel="nofollow">guideline </a> (I use Play 2.3.4), but it does not work. What can be an issue?</p>

dynamic css circle navigation
|
<p>This question is a follow-up question (not sure if thats allowed) on something I asked earlier -> <a href="https://stackoverflow.com/questions/34307941/dynamic-css-circle-inside-div">dynamic css circle inside div</a></p>
<p>The solution to that thread turned out not be what I wanted to achieve since I need the divs adjacent to the centered circle to be independent of it in order not to be affected by styles such as opacity i want to apply to the circle.</p>
<p>What I want to create is a page in which I have a fixed header and footer and a circle in the content area that dynamically changes size depending on the space available - i dont want to user to scroll.</p>
<p>Abovementioned circle has a div (the navigational part) on either side that will also change size. </p>
<p>The code that I have so far seems to work as expected when the x-axis of the wrapper is bigger than the y-axis (width > height) but for some reason when the height of the wrapper is bigger than width, it gets all distorted.</p>
<p><a href="https://jsfiddle.net/h1xfqwh6/" rel="nofollow noreferrer">https://jsfiddle.net/h1xfqwh6/</a></p>
<p>looking at in in fiddle it actually looks half decent - besides the hidious colors - which are a feature... but if i look at in the firefox responsive design developer mode the circle takes always more space than it should when the wrapper containers height is larger than its width - </p>

Display an error if a latitude or longitude has improper formatting
|
<p>My WPF application has a dialog where the user can enter a latitude & a longitude. I have written an <code>IValueConverter</code> which can handle values entered as decimal degrees or in degree-minute-second format:</p>
<pre><code>[ValueConversion( typeof( double? ), typeof( string ) )]

} else {
return value.ToString();
}
bool isNegative = angle < 0;
if ( isNegative ) angle = -angle;
double degrees = Math.Truncate( angle );
double remainder = ( angle - degrees ) * 60.0;
double minutes = Math.Truncate( remainder );
double seconds = ( remainder - minutes ) * 60.0;
string result = degrees.ToString( "##0", culture.NumberFormat ) + "° " +
minutes.ToString( "#0", culture.NumberFormat ) + "' " +
seconds.ToString( "#0.00", culture.NumberFormat ) + "\" ";
// The parameter contains "NS" for Latitudes and "EW" for Longitudes.
if ( parameter != null ) {
result += ( (string) parameter ).Substring( ( isNegative ? 1 : 0 ), 1 );

// Parse the value in the field. It's in three parts: Degrees, minutes & seconds
int degreeSymbol = strValue.IndexOf( "°" );

double angle, d, m, s;

<p>In the dialog, I'm using this <code>ControlTemplate</code> to display errors:</p>
<pre><code><ControlTemplate x:Key="InputErrorTemplate">
<DockPanel LastChildFill="True">
<Image DockPanel.Dock="Right"
Height="20"
Margin="-30,0,0,0"
Source="{StaticResource ErrorImage}"
ToolTip="{x:Static res:Car.Common_InvalidData}"
VerticalAlignment="Center"
Width="20" />
<Border BorderBrush="Red"
BorderThickness="5"
Margin="5,0,30,0">
<AdornedElementPlaceholder />
</Border>
</DockPanel>
</ControlTemplate>
</code></pre>
<p>If one of the <code>TextBoxes</code> has a string in it like , it doesn't parse, no exceptions are thrown, and my dialog's error template is displayed. When I hover the mouse over the <code>TextBox</code>, the error message displayed is "Input string is not in a correct format"</p>
<p>I have a couple of questions:</p>
<ol>
<li>Where is that error message coming from? It's not in my code and if the converter throws an exception, the program dies as it's unhandled. </li>
<li>In the end, I want to display an error if the value in the <code>TextBox</code> can't be parsed. The dialog's View Model object does implement <code>IDataErrorInfo</code>, but the conversion from string to double isn't being done by that object. How do I make that happen?</li>
</ol>

Ajax URL Not Executing The Correct Function in views.py As Defined in urls.py
|
<p>I am leveraging Ajax for some pie charts but data-ajax-url is not working as intended (or as I thought). Per urls.py, reptibase:item-update should execute the item_update function in my views.py file. item_update never gets executed though and instead the same function associated with the current pages url is executed again.</p>
<p>Currently, am getting a parsing error because HTML is coming back instead of json. json is returned from my item_update function though.</p>
<p>item.js</p>
<pre><code>window.onload = function () {
console.log("Child: ", document.getElementById("piee"))

How can I get rows with specific conditions in r
|
<p>Say that I have a <code>df</code>.</p>
<p>I want to get the <code>id</code> with two conditions at the same time:</p>
<ol>
<li><p>the <code>id</code>'s <code>code</code> should contaions a capital <code>I</code>, regardless of the number that follows it. For example <code>I11</code>, <code>I31</code>...</p>

</li>

boostrap 3 + datatables buttons: misalignment
|
<p>I'm experiencing misalignment when using boostrap 3 and datatables buttons (<a href="https://datatables.net/extensions/buttons/" rel="nofollow noreferrer">https://datatables.net/extensions/buttons/</a>). How to align them propery?
<a href="https://i.stack.imgur.com/Eyki8.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Eyki8.png" alt="enter image description here" /></a></p>
<p>everything works fine when on <code>div.dt-buttons</code> margin is set <code>margin-top:2px;</code>, don't know why, but it feels wrong is there any "standard way"?</p>

Decrypt AES with wrong IV size
|
<p>I have a file encrypted in AES 128 CBC (with openssl in cpp). The encryption has been done with a wrong iv size (8 instead of 16). It's a fact, it's wrong and I can't do anything about it.
The file I get is like this:<br>
[8 bit of IV][Encrypted data]</p>
<p>I have to read this file with Java (android) but I cannot get a correct result.</p>
<p>Here is what I'm using to decrypt the file: </p>
<pre><code>public String decrypt(byte[] key, byte[] datasencrypted) {
// Split IV and actual Datas into 2 differents buffers
int dataSize = datasencrypted.length - 8; // 8 = wrong iv size
byte[] encrypted = new byte[dataSize];
byte[] ivBuff = new byte[8];
System.arraycopy(datasencrypted,0,ivBuff,0,8);
System.arraycopy(datasencrypted,8,encrypted,0,dataSize);
try {
IvParameterSpec iv = new IvParameterSpec(ivBuff);
SecretKeySpec skeySpec = new SecretKeySpec(key, "AES");
Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5PADDING");
cipher.init(Cipher.DECRYPT_MODE, skeySpec, iv);
byte[] original = cipher.doFinal(encrypted);
return new String(original);
} catch (Exception ex) {
ex.printStackTrace();
}
return null;
}
</code></pre>
<p>Obviously this code throw me an InvalidAlgorithmParameterException: expected IV length of 16. If I change the size of the iv's buffer to 16 no more exception but the end result is just gibberish.</p>
<p>Also the key is defined as unsigned char[] in CPP so to convert it to byte[] in java I simply cast the values like this: </p>
<pre><code>mKey = new byte[]{(byte)0x8c,(byte)0x96,0x5f,.....}};
</code></pre>
<ul>
<li>Is it possible to decrypt this file in java (it's working on the cpp side)?</li>
<li>How should I know which kind of padding to use?</li>
<li>Does the cast of the key value may be a problem?</li>
</ul>
<p>--- EDIT ---
As suggested here is the CPP code that manage to decrypt the file :.
AES_KEYLEN = 128.<br>
AES_ROUND = 5. </p>
<pre><code>size_t Helper::DecryptAES(unsigned char* encMsg, size_t encMsgLen, unsigned char** decMsg)
{
size_t decLen = 0;
size_t blockLen = 0;
*decMsg = (unsigned char*)malloc(encMsgLen);
if (*decMsg == nullptr) return 0;
if (!EVP_DecryptUpdate(mAESDecryptCtx, (unsigned char*)*decMsg, (int*)&blockLen, encMsg, (int)encMsgLen)) {
return 0;
}
decLen += blockLen;
if (!EVP_DecryptFinal_ex(mAESDecryptCtx, (unsigned char*)*decMsg + decLen, (int*)&blockLen)) {
return 0;
}
decLen += blockLen;
return decLen;
}
bool Helper::InitAES(unsigned char* key, unsigned char* salt)
{
mAESEncryptCtx = static_cast<EVP_CIPHER_CTX*>(malloc(sizeof(EVP_CIPHER_CTX)));
mAESDecryptCtx = static_cast<EVP_CIPHER_CTX*>(malloc(sizeof(EVP_CIPHER_CTX)));
mAESKey = static_cast<unsigned char*>(malloc(AES_KEYLEN / 8));
mAESIv = static_cast<unsigned char*>(malloc(AES_KEYLEN / 8));
int size = EVP_BytesToKey(EVP_aes_128_cbc(), EVP_sha256(), salt, key, AES_KEYLEN / 8, AES_ROUNDS, mAESKey, mAESIv);
if (size != AES_KEYLEN / 8)
{
return false;
}
EVP_CIPHER_CTX_init(mAESEncryptCtx);
if (!EVP_EncryptInit_ex(mAESEncryptCtx, EVP_aes_128_cbc(), nullptr, mAESKey, mAESIv))
return false;
EVP_CIPHER_CTX_init(mAESDecryptCtx);
if (!EVP_DecryptInit_ex(mAESDecryptCtx, EVP_aes_128_cbc(), nullptr, mAESKey, mAESIv))
return false;
return true;
}
</code></pre>
<p>IvSIze is ok here , but it's when the iv is concatened to the file that only 8 bits are read instead of 16.</p>

Typescript - Why does this recursive function skips some numbers?
|
<p>From the server, I receive this JSON object. It represents an organigram of a company and the associated departments. </p>
<p>I need to be able to choose a company, and with the ID of the company, I need to pass to an array of numbers the ID's of the associated departments.</p>
<p>For that, I've created this recursive function. It works, but, skips 3 departments, which are placed within another department</p>
<p>This is the JSON file</p>
<pre><code>{
"cd": 1,
"cd_base": 0,
"nome": "EMPRESA A",
"children": [
{
"cd": 2,
"cd_base": 1,
"nome": "Departamento A",
"children": [
{
"cd": 4,
"cd_base": 2,
"nome": "Serviço A1",
"children": []
},
{
"cd": 15,
"cd_base": 2,
"nome": "Serviço A2",
"children": []
}
]
},
{
"cd": 3,
"cd_base": 1,
"nome": "Departamento B",
"children": [
{
"cd": 7,
"cd_base": 3,
"nome": "Serviço B1",
"children": []
}
]
},
{
"cd": 186,
"cd_base": 1,
"nome": "Departamento XX",
"children": []
}
]
}
</code></pre>
<p>And this is the function in Typescript</p>
<pre><code>recursiveFunction(res: any): any[] {
const numbers = new Array(); // to store the ID
console.log('Im on ' + res.cd + ' | ' + res.nome);
numbers.push(res.cd);
if (res.children.length > 0) {
console.log(res.cd + ' | ' + res.nome + ' has children');
res.children.forEach((row) => {
numbers.push(row.cd);
this.recursiveFunction(row);
});
} else {
console.log(res.cd + ' | ' + res.nome + ' doesn\'t have any children');
}
return numbers;
}
</code></pre>
<p>And this is the return of that function to the console</p>
<pre><code>Im on 1 | EMPRESA A
1 | EMPRESA A has c
Im on 2 | Departamento A
2 | Departamento A has children
Im on 4 | Serviço A1
4 | Serviço A1 doesn't have any children
Im on 15 | Serviço A2
15 | Serviço A2 doesn't have any children
Im on 3 | Departamento B
3 | Departamento B has children
Im on 7 | Serviço B1
7 | Serviço B1 doesn't have any children
Im on 186 | Departamento XX
186 | Departamento XX doesn't have any children
</code></pre>
<p>Then I log the <em>numbers</em> array and the result is <em>1,2,3,186</em></p>
<pre><code> this.numbers.forEach(row => {
console.log(row);
});
// 1, 2, 3, 186
</code></pre>
<p>It adds the CD 1, 2, 3 and 186, but skips the 4, 7 and 15.
All of those are a branch/node <strong>within</strong> another branch/node</p>
<p>What am I missing? Is recursive the best way to do this? Is there a simpler way?</p>
<p>Any help is appreciated</p>

Java components being hidden in JPanel

Adding calls inside QgraphicsRectItem subclass triggers infinite redraw
|
<p>I have a hierarchy of object types, inheriting from a custom interface and <code>QGraphicsItem</code>.</p>
<p>In hope of optimizing the code, I would like to inherit from <code>QGraphicsSomethingItem</code>. Example: rectangle</p>
<pre><code>class RectangleItem : public Item, public QGraphicsItem
{
RectangleItem() : Item() // Item initializes m_pen, m_brush
{
setFlags(QGraphicsItem::ItemIsMovable |
QGraphicsItem::ItemIsFocusable |
QGraphicsItem::ItemIsSelectable);
}
QRectF RectangleItem::boundingRect() const
{
return QRectF(-50, -50, 100, 100);
}
void RectangleItem::paint(QPainter* painter, const QStyleOptionGraphicsItem* option, QWidget* widget)
{
Q_UNUSED(option);
Q_UNUSED(widget);
setItemPen(); // calculates m_pen in class Item
setItemBrush(); // calculates m_brush in class Item
painter->setPen(m_pen);
painter->setBrush(m_brush);
painter->drawRect(boundingRect());
}
}
</code></pre>
<p>This works perfectly.</p>
<p>Now trying the same thing but inheriting from <code>QGraphicsRectItem</code></p>
<pre><code>class RectangleItem : public Item, public QGraphicsRectItem
{
RectangleItem() : Item() // Item initializes m_pen, m_brush
{
setRect(-50, -50, 100, 100);
setFlags(QGraphicsItem::ItemIsMovable |
QGraphicsItem::ItemIsFocusable |
QGraphicsItem::ItemIsSelectable);
}
QRectF RectangleItem::boundingRect() const
{
return QRectF(-50, -50, 100, 100);
}
void RectangleItem::paint(QPainter* painter, const QStyleOptionGraphicsItem* option, QWidget* widget)
{
// setItemPen(); // calculates m_pen in class Item
// setItemBrush(); // calculates m_brush in class Item
setPen(m_pen);
setBrush(m_brush);
QGraphicsRectItem::paint(painter, option, widget);
}
}
</code></pre>
<p>This creates an infinite loop<br>
- a breakpoint on <code>setItemPen()</code> showed it kept calling it. So I removed it, along with <code>setItemBrush()</code>. (though I really need to set custom pen)<br>
- a breakpoint on <code>setPen()</code> showed it kept calling it. So I removed it. Same with <code>setBrush()</code><br>
- once there were no things being "set" inside paint, the paint worked.</p>
<p>Of course this is not functional - I need to be able to set item properties, and my understanding is that the call to <code>paint()</code> - happening when a call to update the scene - would update he items. After all, my first example, inheriting from <code>QGraphicsItem</code>, works.</p>
<p>I have found something similar in this <a href="https://stackoverflow.com/a/17338910/1217150">question</a> - but no answer on how to fix it, or no actual explanation why the call to set pen and brush causes a redraw. There is nothing in that code using any of the item's drawing properties, and even more - if I call <code>setPen(m_pen)</code> with the value from constructor, I see nothing to be recalculated...</p>
<p>What triggers the object redraw and how can I avoid it ?</p>

C# How to write each table in a Word file to its own Excel file
|
<p>I'm trying to write code in C# WinForms that allows a user to select a directory tree, and extract all of the table data from a word document into an excel file. Presently, the code compiles and you can select your directories, etc, but once it begins to iterate through the loop for each table it crashes.</p>
<p>The program successfully opens the first word file and writes the first excel file (table_1_whatever.xlsx) and saves it in the destination folder. However, on the second table in the same file I get this error on this line of code:</p>
<pre><code> worksheet.Cells[row, col] = objExcelApp.WorksheetFunction.Clean(table.Cell(row, col).Range.Text);
</code></pre>
<p>System.Runtime.InteropServices.COMException: 'The requested member of the collection does not exist.' </p>
<p>I can't seem to figure out why it doesn't exist. Each time it goes through the foreach loop it should be creating a new worksheet, but it doesn't appear to be working. Any insight, examples, or suggestions are welcome!</p>
<p>Code:</p>
<pre><code> private void WordRunButton_Click(object sender, EventArgs e)
{
var excelApp = new excel.Application();
excel.Workbooks workbooks = excelApp.Workbooks;
var wordApp = new word.Application();
word.Documents documents = wordApp.Documents;
wordApp.Visible = false;
excelApp.Visible = false;
string[] fileDirectories = Directory.GetFiles(WordSourceBox.Text, "*.doc*",
SearchOption.AllDirectories);
foreach (var item in fileDirectories)
{
word._Document document = documents.Open(item);
int tableCount = 1;
foreach (word.Table table in document.Tables)
{
if (table.Cell(1, 1).ToString() != "Doc Level")
{
string wordFile = item;
appendName = Path.GetFileNameWithoutExtension(wordFile) + "_Table_" + tableCount + ".xlsx";
var workbook = excelApp.Workbooks.Add(1);
excel._Worksheet worksheet = (excel.Worksheet)workbook.Sheets[1];
for (int row = 1; row <= table.Rows.Count; row++)
{
for (int col = 1; col <= table.Columns.Count; col++)
{
var cell = table.Cell(row, col);
var range = cell.Range;
var text = range.Text;
var cleaned = excelApp.WorksheetFunction.Clean(text);
worksheet.Cells[row, col] = cleaned;
}
}
workbook.SaveAs(Path.Combine(WordOutputBox.Text, Path.GetFileName(appendName)), excel.XlFileFormat.xlWorkbookDefault);
workbook.Close();
Marshal.ReleaseComObject(workbook);
}
else
{
WordOutputStreamBox.AppendText(String.Format("Table {0} ignored\n", tableCount));
}
WordOutputStreamBox.AppendText(appendName + "\n");
tableCount++;
}
document.Close();
Marshal.ReleaseComObject(document);
WordOutputStreamBox.AppendText(item + "\n");
}
WordOutputStreamBox.AppendText("\nAll files parsed");
excelApp.Application.Quit();
workbooks.Close();
excelApp.Quit();
WordOutputStreamBox.AppendText("\nExcel files closed");
Marshal.ReleaseComObject(workbooks);
Marshal.ReleaseComObject(excelApp);
WordOutputStreamBox.AppendText("\nExcel files released");
wordApp.Application.Quit();
wordApp.Quit();
WordOutputStreamBox.AppendText("\nWord files have been quit");
Marshal.ReleaseComObject(documents);
Marshal.ReleaseComObject(wordApp);
WordOutputStreamBox.AppendText("\nWord files have been released\n");
}
</code></pre>
<p>Edit 1:(Sorry for posting in the wrong place the first time!)</p>
<p>Ok, so the problem has been isolated...</p>
<p>The code logic of the code was fine, and the table was in fact there. The issue is that the second table of these files has a set of split cells in it, so, when it reaches the cell that contains it, the program crashes.</p>
<p>As a temp fix, I have just set it to ignore the table if the header == whatever. Does anyone know of a solution that actually allows to extract this data though?</p>

</code></pre>
<p>Trying this out on my actual device with the GPS already enabled in the settings, I get some odd behavior. If I do not at all, call the <code>startLocationUpdates()</code> method or I call it in the <code>onRequestPermissionsResult()</code> method, the app launches fine and when I grant Device Location Permissions, the <code>mCurrentLocation</code> object is null, but does not crash. I stop the app and then launch again, and the <code>mCurrentLocation</code> has latitude and longitude coordinates that I can see in the logcat, which is what I am wanting in the first place, but they only hold any values, after the second launch. Now if I uninstall the app and try to call the <code>startLocationUpdates()</code> method anywhere, the app crashes upon launch with the error: </p>
<pre><code>Client must have ACCESS_FINE_LOCATION permission to request PRIORITY_HIGH_ACCURACY locations.
</code></pre>
<p>But I am checking for permissions in the <code>onConnected()</code> method and also in the <code>startLocationUpdates()</code> method as well, although I do not think this is correct but this is the only way that I can get Android Studio to not underline the </p>

How can I pass configuration to Database class

<p>I have a database class in which i want to pass configuration. I have to keep the "framework" and the Application files separate.
here is my configuration class
</p>
<pre><code><?php namespace Fzaffa\System;

private $items = [];
public function get($name)
{
list($file, $key) = $this->parseName($name);

</code></pre>
<p>and here is my Database class
</p>
<pre><code><?php namespace Fzaffa\System;
use PDO;

private $host = 'localhost';
private $dbname = 'mycms';
private $user = 'homestead';

$this->dbh = new PDO($dsn, $this->user, $this->pass, $options);
} catch (PDOException $e)
{
$this->error = $e->getMessage();

}
</code></pre>
<p>I would like to be able to instantiate the configuration object in the index.php (where all bootstrapping and routing happens) like so
$config = new \Fzaffa\system\Config;
and then use the config variables inside classes like $class->get('database.username')</p>
<p>The config file being application specific need to stay separate and inside the /App/ folder.</p>
<p>Is there a way I can do it without an IoC container and without having to pass the config object through all the hierarchy to the model (Where I instantiate the \Fzaffa\Sysyem\Database object)?</p>
<p>Thank you in advance.</p>

listCheck = document.createElement('p');
listCheck.id = 'image';
listCheck.innerHTML = "<img src = " + "./images/" + json[i].exhibits[j].exhibit_image + " Photo Cover' height='200' width='200'>";
console.log(listCheck);
myExhibitionsView.appendChild(images);
images.appendChild(listCheck);
console.log(listCheck);
}
}

</code></pre>
<p>This code allows me to extract the json and then use the image urls... this is what i wish to do here as well but only if its of the specific id. Thank you very much for the assistance </p>

Quick Sort using C#
|
<p>Hello I trying to do a QuickSort but didn't appear the result, For example the user input "cdabe" so the expected result is "abcde". May I know what is the cause why the result didn't display?
because There is no error in the code. I'm using MVC. My MergeSort is working properly but my QuickSort didn't.</p>
<p>Model :</p>
<pre><code>public string QuickSort()
{
string arrangedSort = "";
string Word= "cdabe";
List<string> ListLetters = new List<string>();
for (int i = 0; i < Word.Length; i++)
{
ListLetters.Add(Word.Substring(i, 1));
}
aQuicksort(Word, 0, ListLetters.Count - 1);
void aQuicksort(string Word, int left, int right)
{
int i = left;
int j = right;
var pivot = Word[(left + right) / 2];
while (i <= j)
{
while (char.Parse(ListLetters[i]) < pivot)
i++;
while (char.Parse(ListLetters[i]) > pivot)
j--;
if (i <= j)
{
var tmp = ListLetters[i];
ListLetters[i] = ListLetters[j];
ListLetters[j] = tmp;

}
if (left < j)

if (i < right)
aQuicksort(Word, i, right);
foreach (var listLetter in ListLetters)
{
arrangedSort += listLetter;
}

AJAX Request in CodeIgniter Application Failing After Inactivity
|
<p>The application I am working on is built in CodeIgniter, and the content is always loaded via ajax into the main content div.</p>
<p>This works without fail normally, apart from after the user has been inactive for a short while.</p>
<p>We haven't completely narrowed down the inactivity time required for the request to fail, but it's around 40 minutes or more of inactivity.</p>
<p>I've tried logging details to the console in the error callback of the AJAX request, but nothing is logged.</p>
<p>I'm thinking that it's related to a session expiry but I can't be sure. I know when using CodeIgniter, there are two sessions which are created automatically (PHPSESSID, and ci_session) so my instinct is that it has something to do with these, or one of them, expiring?</p>
<p>When the request fails the headers, preview, response and cookies tab on chrome's developer tools show nothing.</p>
<p>If anyone has experienced this before, or has any ideas what may be causing the problem, I'd appreciate the input.</p>
<p><strong>Edit:</strong></p>
<p>Below is the AJAX request which is experiencing the above problem.</p>
<p>All links within my application use this loadPage function instead of a standard redirect.</p>

<p><strong>Edit 2:</strong></p>
<p>After putting several console log's through the function, to see at which point it breaks. The problem decided to disappear. For what reason would adding console logs to the function prevent this issue from occurring?</p>
<p>I'm currently waiting an hour or so to re-test it without the console logs to make sure it isn't a red herring.</p>
<p><strong>Edit 3:</strong></p>
<p>After putting in console logs in the error callback of the AJAX request, it seems that the error callback is not firing. Not quite sure where to look now - as if it was a success, it would surely return the content.</p>

How to add the "Access-Control-Allow-Credentials" request header to a POST request in ASP.NET?
|
<p>So, I am trying to set the "Access-Control-Allow-Credentials", using the <code>HttpContext.Request.Headers.Add("Access-Control-Allow-Credentials", "true"); </code>, but it will only work for my GET requests, but not for my POST ones, and i don't know why.</p>
<p>I've also tried to set those in Startup.cs, as so:</p>
<pre><code> services.AddCors(o => o.AddPolicy("ApiCorsPolicy", builder =>
{
builder
.WithOrigins("My_Web_App")
.AllowCredentials()
.AllowAnyMethod()
.AllowAnyHeader();
}));
</code></pre>
<p>And then use it in Configure with <code>app.UseCors("ApiCorsPolicy");</code></p>
<p>That's the code from my controller, so nothing fancy in here, I think:</p>
<pre><code> [ApiController]
[Route("[controller]")]
[EnableCors("ApiCorsPolicy")]
public class UserController : Controller
{
private readonly IUserService _userService;
public UserController(IUserService userService)
{
_userService = userService;
}
[HttpPost("RegisterUser")]
public void GetTournaments([FromBody] UserDTO user)
{
HttpContext.Request.Headers.Add("Access-Control-Allow-Credentials", "true");
_userService.RegisterUser(user);
}
}
</code></pre>
<p>My question is, why I can't put the "Access-Control-Allow-Credentials" header using the <code>Headers.add</code> method( Which works for my GET requests ) ? If that is not the correct approach to it, then how to do it ?
Thanks!</p>
<p>Edit:
I've added all my Startup file, as requested:</p>
<pre><code> public class Startup
{
public Startup(IConfiguration configuration)
{
Configuration = configuration;
}
public IConfiguration Configuration { get; }
public void ConfigureServices(IServiceCollection services)
{
services.AddCors(o => o.AddPolicy("ApiCorsPolicy", builder =>
{
builder
.WithOrigins("http://"MyIpAddressHere"/")
.AllowAnyMethod()
.AllowAnyHeader();
}));
var mapperConfig = new MapperConfiguration(mc =>
{
mc.AddProfile(new MappingGeneral());
});
IMapper mapper = mapperConfig.CreateMapper();
services.AddSingleton(mapper);
services.AddSingleton<ITournamentService, TournamentService>();
services.AddSingleton<IUserService, UserService>();
services.AddControllers();
services.AddSwaggerGen(c =>
{
c.SwaggerDoc("v1", new OpenApiInfo { Title = "my_app", Version = "v1" });
});
}
// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
app.UseSwagger();
app.UseSwaggerUI(c => c.SwaggerEndpoint("/swagger/v1/swagger.json", "my_app v1"));
}
app.UseRouting();
app.UseCors("ApiCorsPolicy");
app.UseAuthorization();
app.UseEndpoints(endpoints =>
{
endpoints.MapControllers();

Gitlab CICD sets wrong service url in the production environment

<p>What I have done so far:</p>
<ul>
<li>removed deployment from cluster, cleared the Gitlab runners cache, cleared the Gitlab cluster cache. Deleted the environment (stop and delete). Created a new environment 'production' with the right URL 'Operations>Environments>production>Edit'. After push the url has been replaced with the wrong one.</li>
<li>hard coded the url in Ingress (at the arrows in the snippet), it worked</li>
<li>changed the value in gitlab-ci.yml without http://. No result.</li>
<li>check the use of 'apply production secret configuration' in the gitlab-ci.yml, by adding echo 'message!'. Conclusion: this part of the file is used for production</li>
<li>A CICD variable Settings>CICD: GITLAB_ENVIRONMENT_URL. No effect.</li>
</ul>
<p>UPDATE:
Maybe the <code>.Values.gitlab.app</code> is used for the URL.</p>

How to correct a mess java .class file set or generate a proper .jar archive from a mess .class set?
|
<h1>Background</h1>
<p>I have to contact different kind of Java project with various of build system. Sometimes the directory structure is different from the package hierarchy. So it is difficult to package.</p>
<p>Even if the build system like Maven and Gradle have its own function to pack .jar but it need a qualified internet connection and a giant size of local repository. Hence I usually build the library I need on the desktop in my office. However I spend more time on my laptop which doesn't have such good connection and storage.</p>
<h1>Question</h1>
<p>Is there a stable, compatible and secure way to make .jar package? Or move those .class file to appropriate directory? (An official and mature open source tool is better)</p>
<p>I am a beginner of Java Language, so any point may be helpful for me.</p>
<h2>In order to make it clearly, here I put some examples.</h2>
<h3>Case 1: If there is a tool which can moving (moving or copying) the .class file in correct directory it should behave as below:</h3>
<p>Before operation:</p>
<pre><code>from_root/
├── a.class
├── b.class
├── c.class
├── d.class
├── e.class
└── f.class
</code></pre>
<p>Note in each source file(.java) of .class file, there is package announcement(like <code>package org.hello.world;</code> or <code>package org.hello;</code>)</p>
<p>when typing <code>the_tool ./from_root ./to_root</code> in shell</p>
<p>it will become:</p>
<pre><code>to_root/
└── org
└── hello
├── a.class
├── b.class
└── world
├── c.class
├── d.class
├── e.class
└── f.class
</code></pre>
<h3>Case 2: If there is a tool which can packing correct .jar file from mess .class file directory it should behave as below:</h3>
<p>Before operation:</p>
<pre><code>from_root/
├── a.class
├── b.class
├── c.class
├── d.class
├── e.class
└── f.class
</code></pre>
<p>when typing <code>pack_tool ./from_root ./to_root/pack.jar</code> in shell</p>
<p>A <code>pack.jar</code> will be generate in <code>./to_root</code>.</p>
<p>When add it in Java Build Path of Eclipse, it should be imported and called properly, instead of wrong name-space hierarchy .</p>
<h1>What I have tried</h1>
<h2>For some famous 3rd part library (e.g. apache tika)</h2>
<p>It is build by maven, and I typed <code>cd /path/to/tika-1.18-src/tika-1.18/</code> then I typed <code>mvn package</code>.</p>
<p>Unfortunately, it was failed.</p>
<p>However when I typed <code>mvn compile</code>, everything went right.</p>
<p>Then in order to build .jar package, I typed <code>jar cvf ./build/tika-1.18.jar $(find ./ -name org | grep target)</code> in terminal.</p>
<p>However, the structure inside the .jar package was totally wrong. I couldn't use it in my project.</p>
<p>Then I tried <code>find ./ -name org | grep target | parallel cp {} ./build/ -R -f</code> then <code>cd ./build</code> and finally <code>jar cvf ./tika-1.18.jar org</code>.</p>
<p>It worked. However there is some disadvantage of this method.</p>
<h3>Shortcoming:</h3>
<ol>
<li><p>If the some source file(.java file)'s name include 'target', it will cause big trouble.</p>
</li>
<li><p>If different subproject contain same file it will cause conflict. For example here is the conflict information:
cp: cannot create directory './build/org/apache/tika/batch': File exists
cp: cannot create directory './build/org/apache/tika/language/translate': File exists</p>
</li>
<li><p>This method can only handle the situation which the path of those .class file is partly correct. If all the .class file are located in same directory flatly, it will failed to work.</p>
</li>
</ol>
<h3>Another attemption</h3>
<p>I tried to put the .class file in correct directory according to its binary content.</p>
<p>For example, <code>org.apache.tika.detect.AutoDetectReader</code></p>
<pre><code>$ hexdump -C /path/to/here/EncodingDetector.class

<p><strong>What's amazing is the content after "...SourceFile..." is the package location of this class.</strong></p>
<p>It is possible to write a program which can scan every .class file and determine their location in the directory. However, there is Java 9, Java 10 and Java 11 will coming soon. different java version will cause the different binary content of .class files. And it might be different between JDK and OpenJDK. So it is not compatible enough. But on the other hand, it shows that it is possible to determine the package location of a certain .class file without other infomation.</p>
<p><strong>Hope someone can provide some ideas, thanks sincerely!</strong></p>

Accessing and Modifying AppDelegate OUTSIDE Itself
|
<p>In my <strong>viewController</strong>, there's an object of a custom <strong>PolyShape</strong> class. The main variable of it is the number of sides and this modifies everything else in the app.</p>
<p>I'm trying to use the <strong>AppDelegate</strong> and <strong>NSUserDefaults</strong> to store the number of sides on the <strong>NSUserDefault</strong>, but my problem is communicating between the <strong>AppDelegate</strong> and my <strong>viewController</strong>.</p>
<p>I saw that you can make a call to the <strong>AppDelegate</strong> with this line of code
YourAppDelegate *appDelegate = (YourAppDelegate *)[[UIApplication sharedApplication] delegate];
which doesn't seem to work for me.</p>
<p>But supposing this DID work and I was able to call the value out of the AppDelegate, how would I write it back in the the app is about to close? Here's my code so far:</p>
<pre><code>@synthesize window = _window;
@synthesize polySides;
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
[self setPolySides: [[NSUserDefaults standardUserDefaults] integerForKey:@"polysides"]];
[self.window makeKeyAndVisible];
return YES;
}
- (void)applicationWillResignActive:(UIApplication *)application {
/*
Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state.
Use this method to pause ongoing tasks, disable timers, and throttle down OpenGL ES frame rates. Games should use this method to pause the game.
*/
[[NSUserDefaults standardUserDefaults] setInteger: self.polySides forKey:@"polysides"];
}
- (void)applicationDidEnterBackground:(UIApplication *)application {
/*
Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later.
If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits.
*/
[[NSUserDefaults standardUserDefaults] setInteger: self.polySides forKey:@"polysides"];
}
- (void)applicationWillEnterForeground:(UIApplication *)application
{
/*
Called as part of the transition from the background to the active state; here you can undo many of the changes made on entering the background.
*/
[self setPolySides: [[NSUserDefaults standardUserDefaults] integerForKey:@"polysides"]];
}
- (void)applicationDidBecomeActive:(UIApplication *)application {
/*
Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.
*/
}
- (void)applicationWillTerminate:(UIApplication *)application {
/*
Called when the application is about to terminate.
Save data if appropriate.
See also applicationDidEnterBackground:.
*/
[[NSUserDefaults standardUserDefaults] setInteger:polygon.numberOfSides forKey:@"polysides"];
}
- (void)dealloc {
[_window release];
[super dealloc];
}
</code></pre>
<p><strong>EDIT:</strong> I guess I wasn't clear. What I want to be able to do is the following:</p>
<pre><code>[[NSUserDefaults standardUserDefaults] setInteger: polygon.numberOfSides forKey: @"polysides"];
</code></pre>
<p>where polygon is an object in my controller. Similarly I'd like to be able to do</p>
<pre><code>[polygon.setNumberOfSides: [[NSUserDefaults standardDefaults] integerForKey: @"polysides"];
</code></pre>

MySQL deleting records that only exist in child table/cakephp update?
|
<p>I have two Myisam tables, let's say Parent and Child. Parent is created in a perl script. Parent is where the child gets the information(Not for editing) that's all the same, while Child holds information unique to it. Following Cakephp naming conventions, they're connected through the Parent's id field and the child's parent_id. When the Parent table is updated through another application(A record being added via Perl) it shows up in Child but if a record is deleted, Child doesn't update. Is there a way following cakephp conventions to have the table update(Removing the record that was deleted in Parent)?
I do have 'dependent' => true in the parent table for the child? Does that need to be in the child table? Or does that not matter since the table is updated outside of the app?</p>
<p>If nothing else, I can maybe set up a cron job to check the tables periodically, but i'm not sure how to find/delete the records in the child table that no longer exist in the Parent table via <strong>MYSQL</strong>. A combination of joins and where such n such <>? So my question(s) are can i do it with cakephp if the table is updated outside of the app? Or how would I do it with mysql?</p>
<p>Code:</p>

Grade checking program keeps auto exiting prematurely
|
<p>I am currently trying to learn C++ and I have written the following program. It does what it should successfully, however it keeps auto exiting. I have tried putting a <code>cin</code> at the end and when that didn't work I put a <code>getChar()</code> and it doesn't wait for any input. To be clear, I have had no formal education regarding C++ and this problem has had me stumped. I have tried googling it but all that comes up is it telling me to use either of the things I have already tried. I have commented out the <code>cin</code> breakpoints to show where I put them.</p>
<p>As I said earlier, the actual code for the program is below. Underneath that is the debug log.</p>
<p>For what it's worth, I used Visual Studio to make this.</p>
<p><strong>Edit</strong>: This isn't a duplicate question as I want to be able to go the actual executable, double click it and get it to wait for me to press a key until it exits. With this program even if I go to the actual executable, it still auto exits.</p>
<h2>Code</h2>
<p>Code for the program:</p>
<pre><code>#include <iostream>
#include <string>
using namespace std;
// Declare variables for intro
string intro = "Please enter your score.\n";
string prompt = ">>> ";
string nl = "\n";
// Declare grade calculation variables
int initial_grade = 0;
bool temp;
// Declare variables for perfection test
string perfect_score = "You scored perfectly, congratulations!\n";
void perfection_test() {
switch (initial_grade) {
case 100:
cout << perfect_score;
//cin;
}
//cin;
}
int main() {
cout << intro << prompt;
cin >> initial_grade;
cout << nl;
//cin;
perfection_test();
//cin;
}

compareTo with objects returns a false while it is true
|
<p>I am trying to check whether my levelorder of my Binary Search Tree is equal to the other one. To do this, I tried to make a compareTo method. I only give equal values to the method, but it keeps on saying the condition is false. When I place breakpoints, I see that the values are still equal. I am probably not understanding it correctly. Does anyone know how to solve this?</p>
<p>Here is what I did, as you can see below, the compareTo returns a 1 instead of a 0:</p>

Random r = new Random();
Set<Integer> tes = new LinkedHashSet<>(size);
Stack<Integer> stack = new Stack<>();
while (tes.size() < size) {
tes.add(r.nextInt(10));
}
System.out.println("possible combinations");

BST<String, Integer> bst2 = new BST<String, Integer>();
String key1 = d.get(index);
String key2 = d.get(index);

Autolayout redraws when animating
|
<p>So I have a <strong>Parent</strong> (ViewController) and a <strong>SubView</strong> (Slider) in which the SubView has a datePicker and a button. </p>
<p>The Subview itself is a class that uses auto layout to put the datePicker and Button in place so when this view is called, the datePicker and button are in place universally with different screen size of iPhones.</p>
<p><strong>The Problem:</strong> When this subView (Slider) is called from the parent view, it seems that the components inside this view are drawn on runtime from left to right and it looks bad in my opinion.</p>

<p>What am I doing wrong? I seem to think that auto layout in the slider should hold all the components in place and should not draw themselves when the view is called. Any suggestions? </p>

</code></pre>
<p>So basically the Grids are bound to a column change and when that columns value is <code>"new"</code>, the script triggers the dialogue (code above). What is happening is that when I click the <code>Save & Close</code> button, I get <code>"Uncaught TypeError: Cannot read property 'toString' of undefined"</code>. What I do not understand is that I am using a logic test to check for undefined and it appears to be executing the if block anyway which it shouldn't.</p>

Value not available within a private class
|
<p>My php script has two sql statements. The second one (connection 2) is not executing. I believe its because the value for 'id' is not set since it's within a private class. I was wondering if anyone had a suggestion on how to fix this?</p>

Spring JPA Data: Query ElementCollection
|
<p>I have an entity with an elementCollection:</p>
<pre><code>@Entity
class Customer {
@Column(name = "id")
int id;
String name;
@ElementCollection
@CollectionTable(
joinColumns = @JoinColumn(name = "customer_id")
Set<Address> addresses;
}
@Embeddable
class Address {
@Column(name = "address_id")
String id;
String data;
}
</code></pre>
<p>of course the matching data on the db:</p>
<pre><code>databaseChangeLog:
- changeSet:
id: 1
author: me
changes:
- createTable:
tableName: customer
columns:
- column:
name: id
type: bigint
autoIncrement: true
constraints:
primaryKey: true
nullable: false
- column:
name: name
type: varchar(255)
- createTable:
tableName: address
columns:
- column:
name: customer_id
type: bigint
constraints:
nullable: false
- column:
name: address_id
type: varchar(30)
- column:
name: data
type: varchar(255)
- addForeignKeyConstraint:
baseTableName: address
baseColumnNames: customer_id
referencedTableName: customer
referencedColumnNames: id
constraintName: fk_customer_id
- addUniqueConstraint:
tableName: address
name: unique_address_id
columnNames: address_id
</code></pre>
<p>Note: address id is really a String!</p>
<p>Inserting, and reading works. But my goal is to select <code>Customer</code> by <code>Address.id</code>.</p>
<p>My goal:</p>
<pre><code>interface CustomerJpaRepository extends JpaRepository<Customer, Long> {
XXXX // <-- insert solution here
}
</code></pre>
<p>My ideas for XXXX:</p>
<ol>
<li>Using spring data JPA:</li>
</ol>
<pre><code> Customer findByAddressWithId(String addressId);
</code></pre>
<p>Of course, this does not work, because the syntax is wrong. But I can't even find a description of the complete syntax for ElementCollections.</p>
<ol start="2">
<li>Using a custom query:</li>
</ol>
<pre><code> @Query(value = "select c from Customer c join Address a where a.id = '?1'")
Customer findByStreet(String addressId);
</code></pre>
<p>This one does not work because <code>a.id</code> can't be found.</p>
<p>Unfortunately, none of the above work.
Does anybody have any solution for <code>XXXX</code>?</p>

<p>I'm trying to create a superclass that will be able to handle multiple different types of calendars and perform operations on them. The example I'm showing is a function within the superclass that converts the day of the year to the date by using information from the <code>Shire_Calendar</code> subclass.</p>
<p>In order to handle leap years, I want to assign two different variables for months and days in a month (<code>months_norm</code>, <code>months_leap</code>, <code>length_norm</code>, <code>length_leap</code>), that are specified within the calendar subclass, in this case <code>Shire_Calendar</code>, and then the <code>_is_leap_year</code> function within the superclass reads the year input, determines if it is a leap year, and assigns the appropriate month tuple and days in a month tuple to the general variables <code>months</code> and <code>length</code>. From there, the general variables are passed on to the function <code>day_of_year_to_date</code>.</p>
<p>The problem is that when I try to pass these variables, it spits out a name error that <code>Shire_Calendar</code> has no attribute <code>length</code>. It's as if within the <code>_is_leap_year</code> function, <code>months</code> and <code>length</code> are not being assigned, or being assigned to the wrong place.</p>

Issue trying to get website to work - possible issue with my html code?
|
<p>SO I have code that I'm trying to implement from my jsfiddle into an actual working website/mini-app. I've registered the domain name and procured the hosting via siteground, and I've even uploaded the files via ftp so I'm almost there...</p>
<p>But I'm thinking there's something wrong with my HTML code or JS code or how I implemented my JS code into my HTML code, because all of the HTML and CSS elements are present, but the javascript functionality is absent.</p>
<p>Here is my fiddle:</p>
<p><a href="http://jsfiddle.net/sean1rose/sKadX/33/" rel="nofollow">jsfiddle</a></p>
<p>^^ Click on start to see the display in action (which doesn't work in the actual website, which leads me to believe there's an issue with my JS file - whether it be code-related or whether that's because I integrated the file incorrectly) (or maybe even uploaded to the server incorrectly, perhaps?)...</p>
<p>And here is the actual site:</p>
<p><a href="http://www.abveaspirations.com/index.html" rel="nofollow">http://www.abveaspirations.com/index.html</a></p>
<p>And here's my HTML code uploaded to the server via FTP:</p>

Pytest core dump on Unbutu 22.04 LTS when using pyqt5 with mayavi and pyvirtualdisplay
|
<h2>Want I want to do:</h2>
<p>I want to have these requirements running on Ubuntu 22.04 LTS:</p>
<pre><code># Bug on Ub.22.04 but avoids AttributeError: 'Timer' object has no attribute 'start' on other OS
pyqt5==5.15.7
# These together work:
mayavi==4.7.4
PyVirtualDisplay==3.0
pytest==7.1.2
</code></pre>
<p>So I can run this test:</p>
<pre class="lang-py prettyprint-override"><code>import pytest
from pyvirtualdisplay import Display
import os
display = Display(visible=0, size=(1280, 1024))
display.start()
from mayavi import mlab
def foo(tmp_path):
assert 0 == 0;
</code></pre>
<h2>Problem</h2>
<p>Adding the PyQt5 to the list of dependencies seems to break the behavior of the program on Ubuntu 22.04 LTS (although it works on Ubuntu 20.04 LTS and MacOS for multiple version of Python 3.</p>
<p>The output error is the following:</p>
<pre><code>Run python3 -m pip install pytest
python3 -m pip install pytest
cd tests
python3 -m pytest

<h3>Bug reproduction</h3>
<p>I created <a href="https://github.com/Becheler/pyvirtualdisplay-bug" rel="nofollow noreferrer">a small repo</a> to reproduce the issue. I created a bunch of branches where I cut some python dependencies off until I could isolate pyqt5 as the one breaking the working state: the changes are documented in the README. I know using external repos is not ideal, but since in that case it is a Github Action problem (it works on my local Ubuntu 22.04), maybe it makes sense?</p>

Ckeditor5 connection

<p>I use ElFinder as my image editor and ckeditor5 as my editor.</p>
<p>When I call the CKEditor script, it doesn't work :</p>
<pre><code>Uncaught (in promise) TypeError: $(...).dialogelfinder is not a function
</code></pre>
<p>The problem comes from the connector URL :</p>

</code></pre>
<p>Both, the link and the hash are correct. When I click on the image icon it creates this error.</p>
<p>The script inside a function</p>

How do I open a bitmap from a URI that is the result of taking a camera picture?
|
<p>I'm pretty bewildered here and have tried numerous suggestions I've seen on SO. I was following the Xamarin recipe for accessing the camera on Android and taking a picture. There were some things missing/out of date, but regardless I got to the point where I need to call <code>BitmapFactory.DecodeFile</code> so I can open the image the user just took and resize it to display in my view. The problem I ran into is that I can't use file paths, I have to use URIs. So I followed the instructions <a href="https://stackoverflow.com/questions/38200282/android-os-fileuriexposedexception-file-storage-emulated-0-test-txt-exposed">in this SO thread</a></p>
<p>and set up my file provider stuff. I have this file in my resources/xml directory: provider_paths.xml (MyApp being renamed from my actual app details)</p>
<pre><code><?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path name="MyApp" path="."/>
</paths>
</code></pre>
<p>Then in the manifest I added this inside the section:</p>
<pre><code><provider android:name="android.support.v4.content.FileProvider" android:authorities="com.myapp.provider" android:exported="false" android:grantUriPermissions="true">
<meta-data android:name="android.support.FILE_PROVIDER_PATHS" android:resource="@xml/provider_paths" />
</provider>
</code></pre>
<p>I ensure the directory exists by doing:</p>
<pre><code>var file = new File(Environment.GetExternalStoragePublicDirectory(Environment.DirectoryPictures), "MyApp");
Directory = file.AbsolutePath;
if (!file.Exists())
file.Mkdirs();
</code></pre>
<p>(Directory being a string variable).</p>
<p>I create the intent and file name like so:</p>
<pre><code>Intent intent = new Intent(MediaStore.ActionImageCapture);
var file = new File(Directory, $"myPhoto_{Guid.NewGuid()}.jpg");
BaseFilename = file.Name;
_uri = FileProvider.GetUriForFile(MainActivity.Instance, "com.myapp.provider", file);
intent.PutExtra(MediaStore.ExtraOutput, _uri);
intent.AddFlags(ActivityFlags.GrantReadUriPermission);
</code></pre>
<p>(BaseFilename being a string variable in this class)</p>
<p>At first I thought maybe I should somehow convert the URI to a file path so that I can call BitmapFactory.DecodeFile. I followed several SO threads and none of them worked. I got various exceptions when they all started doing ContentResolver.Query or cursor operations. </p>
<p>So I figured, well, there's a BitmapFactory.DecodeStream method, why not use that instead? I tried getting a stream from the URI like so:</p>
<pre><code>var stream = MainActivity.Instance.ContentResolver.OpenInputStream(_uri)
</code></pre>
<p>But when I do this I get an exception: <code>Java.Lang.Exception: open failed: ENOENT (No such file or directory)</code></p>
<p>An example of what the URI looks like when I try this:</p>
<pre><code>content://com.myapp.provider/MyApp/Pictures/MyApp/myPhoto_2d13056f-6d23-461a-ad4b-532e10d9cb75.jpg
</code></pre>
<p>I'm so confused at this point about what's even the problem, and having a hard time with a lot of outdated Xamarin samples that I don't know where to look or what even is the real underlying problem here. Any insight would be greatly appreciated. BTW in case it matters, I at least go the permission stuff right. I already prompted for camera and storage access (I already dealt with errors regarding not having permission for camera/read/write external storage so at least that's over with).</p>

</code></pre>
<p>At the moment when I enter a value that isn't between 1 to 100 in 'vTicketQty' the output is 'NaN' for 'Nett Payment' and 'Discount Amount', how do I get the output value to show an error message instead of NaN?
Also when I don't enter 'a' , 'b' or 'c' for 'vTicketType' the output for 'Nett Payment" is negative, again how do I get the output to show an error message instead?</p>

Error analysing the csv database with javascript

<p>I'm a doing a project for school using IBM's bluemix and I'm having trouble finding out where is my error. I have a database in CSV that has some parameters (neighbourhood, number of rooms, area in square meters, etc). I also have a JADE file that contains a form that the user have to fill in. In this form, the user will choose how many rooms he wants and everything else. Then, my app in JAVASCRIPT should be able to run the database based on the choices of the user. However, for some reason, the results are not appearing in the webpage as they should.</p>

How can this Java tree be 1000 x faster?
|
<p>I am programming an AI for a chess-like game, based on two types of pieces on a 8 x 8 grid.</p>
<p>I want to build a kind of minmax tree, which represents each possible move in a game, played by white players in first, and by black players in second.</p>
<p>I have this generate() method which is call recursively. I need to be able to display about 8 levels of possible moves. Without optimization, this three has 8^8 leafs.</p>
<p>I implemented a simple system which determinate if a grid has actually ever been calculated and if its the case, system just points a child to the ever-calculated child reference.</p>
<p>I don't know if my explanations are clear, I will join a part of code that you should be able to understand.</p>
<p>The problem is that actually, I am able to generate about 3 or 4 levels of all possibilities. I am far of 8.</p>
<p>I would like to be able to calculate it in less than 5 seconds..</p>
<p>So guys, do you see a solution for optimize my algorithm ?</p>
<p>This is the generate function:
leftDiagonalMove(), rightDiagonalMove() and frontMove() return false if a move is illegal or move the piece in the grid and return true, if the move is legal.</p>
<p>clone() creates a new instance with the same properties of it's "parent" and backMove() just step back to last Move.</p>
<pre><code>public void generate(Node root, boolean white, int index) {
Grid grid = root.getGrid();
Stack<Piece> whitePieces = grid.getPiecesByColor(WHITE);
Stack<Piece> blackPieces = grid.getPiecesByColor(BLACK);
Node node;
String serial = "";
// white loop
for (int i = 0; i < whitePieces.size() && white; i++) {
Piece wPiece = whitePieces.get(i);
if (grid.leftDiagonalMove(wPiece)) {
serial = grid.getSerial();
if(!allGrids.containsKey(serial)){
node = new Node(grid.clone());
node.setMove(grid.getLastMove());
root.addChild(node); // add modified grid
allGrids.put(serial, node);
//actualGrid.display();
if (index < 5 && grid.getPosition(wPiece).x > 0)
generate(node, !white, index + 1);
actualGrid.backMove(); // back step to initial grid
}
else{
root.addChild(allGrids.get(serial));
}
}
if (grid.frontMove(wPiece)) {
// same code as leftMove
}
if (grid.rightDiagonalMove(wPiece)) {
// same code as leftMove
}
}
// black loop
for (int i = 0; i < blackPieces.size() && !white; i++) {
Piece bPiece = blackPieces.get(i);
if (grid.leftDiagonalMove(bPiece)) {
// same code as white loop and replacing wPiece by bPiece
}
if (grid.frontMove(bPiece)) {
// same code as white loop and replacing wPiece by bPiece
}
if (grid.rightDiagonalMove(bPiece)) {
// same code as white loop and replacing wPiece by bPiece
}
}

Extract only first occurrence of character and all the numbers before and after hyphen
|
<p>I got into this situation to write a generic function which can extract only first occurrence of the character and all the number from a string.</p>
<p>Input String (Say): ABC123-45DEF-GH67IJ9<br>
Output String: A123-45D-G679</p>
<p>I have finalized an approach but the complexity of the program is high. There are two bad situations for me here:</p>
<ol>
<li>I am getting incorrect output from my program.<br>
<strong>Output:</strong> A123-45D-G679- (This extra hyphen is the issue in the below code).</li>
<li>I need a better approach to get this done in a less complex way.</li>
</ol>
<p><strong>Here is my code snippet:</strong></p>
<pre><code>package Test;
import java.util.LinkedList;
public class FirstLetterAndNumerics {
static void firstLetterAndNumber(String string) {
StringBuffer sb = new StringBuffer();
LinkedList<String> ll = new LinkedList<String>();
String[] str = string.split("-");
boolean flag = true;
for (int i = 0; i < str.length; i++) {
ll.add(str[i]);
}
for (int j = 0; j < ll.size(); j++) {
if (Character.isAlphabetic(ll.get(j).charAt(0))) {

Angularjs – Warn on unsaved changes in Master Detail Scenario
|
<p>I need a solution to warning about unsaved changes in a Master- Detail scenario. I was able to implement a solution by Sam that he created in September 2015 (<a href="http://www.samjhill.com/blog/?p=525#comment-28558" rel="nofollow noreferrer">http://www.samjhill.com/blog/?p=525#comment-28558</a>). This was in response to a stackoverflow question and answer at the link, <a href="https://stackoverflow.com/questions/14852802/detect-unsaved-changes-and-alert-user-using-angularjs">Detect Unsaved changes and alert user using angularjs</a>.</p>
<p>The solution provided by Sam works great with a single form in the html file but I am having problems in a situation I have where I have multiple forms in a header section and detail section where both can change. In the detail section I am using xeditable table. I have tried adding the "confirm-on-exit" attribute to both forms. In the top section the confirmation box comes up as expected but continues to come up even after I submit for update. In the xeditable section the confirmation box never comes up. I have included my html below. Can you offer any suggests I can make so that the warning comes up if a change is made to any form on the page?</p>

<p>I have created a VBA macro to give the format to Sheet in excel and create some subtotals. </p>
<p>It works, but has a lot of room for improvement. </p>
<p>Right now it takes very long. </p>
<p>I know that using Matrix the processing time could be reduced to milliseconds.</p>

How to make a list of PrimaryRowId and Matching RowIds
|
<p>In my previous question (<a href="https://stackoverflow.com/questions/14629325/select-a-distinct-rowid-based-on-series-of-trainnumbers">Select a distinct RowId based on series of trainnumbers</a>) I got a nice list of RowIds.</p>
<p>Now I'd like to make that list complete and totally awesome! :)</p>
<p>My raw data(Excel 2010) looks like this:</p>
<pre><code>Time Wagons Delete DayType Plate trainnumber RowId
05.28 1 1 0901-046 2 38676
08.20 2 1 0901-003 2 18676
05.25 2 x 1 0901-046 2 28676
15.28 2 1 0901-046 2 3676
23.20 3 1 0601-001 2 3867
05.08 3 1 0901-046 2 3876
00.28 L x 1 0901-046 2 8676
00.00 1 0901-046 2 367
</code></pre>
<p>I need a list that groups the Primary RowIds(the list from the previous question) with the RowIds that match it by the following criteria:</p>
<ul>
<li>on the Primary and Matching rows the following must be the SAME:
<ul>
<li>trainnumber</li>
<li>DayType</li>
<li>Time</li>
</ul></li>
<li>on the Primary and Matching rows the Plate must be DIFFERENT</li>
<li>Wagons must be MORE THAN 1 (The column contains rows with numbers, letters and nothing)</li>
<li>Delete must be empty</li>
</ul>
<p>When matches are found, I need the RowId of the match.</p>
<p>Ideally a dataset like this:</p>
<pre><code>PrimaryRowId Match#1 Match#2 Match#3 Match#4
15674 5465 456 5456 45656
5564 231 132 1321 7862
</code></pre>
<p>It's possible that there's more matches per Primary RowId, but that's ok.</p>
<p>My SQL skills is somewhat limited, so that's why I'm asking you guys. :)</p>
<p>I <em>think</em> it might be something like this:</p>
<pre><code>SELECT RowId
FROM Conversion
WHERE trainnumber=trainnumber and daytype=daytype and
time=time and plate<>plate and Wagons>1 and delete=""
GROUP BY RowId
</code></pre>
<p>But it would only give me one(1) RowId at a time. :-/</p>

how to update a table with livewire after deleting a row
|
<p>I have a livewire component that shows a table of client contacts, each row of the table has a delete button which calls a confirm box which uses LivewireUI Modal (<a href="https://github.com/wire-elements/modal" rel="nofollow noreferrer">https://github.com/wire-elements/modal</a>). Upon confirming to delete this component deletes the row from the database but it doesn't refresh the table and remove this deleted element.</p>
<p>In the parent component (the table) I have set a listener <code>protected $listeners =['refreshTable' => '$refresh'];</code> and in the child (confirm popup form) I use <code>$this->emitUp( 'refreshTable' );</code> but it doesn't refresh. I have also used <code>$this->emit( 'refreshTable' );</code> but this didn't work either.</p>
<p>Here are the files:
DeleteContact.php</p>
<pre><code><?php
namespace App\Http\Livewire;
use App\Models\ClientContact;
use LivewireUI\Modal\ModalComponent;
class DeleteContact extends ModalComponent
{
public int $contact_id = 0;
public function render()
{
return view('livewire.delete-contact');
}
public function delete()
{
$contact = ClientContact::find( $this->contact_id );
if ( is_null( $contact->title ) || $contact->title === '' ) {
$contact->forceDelete();
} else {
$contact->delete();
}
$this->closeModal();
$this->emitUp( 'refreshTable' );
}
public static function closeModalOnEscape(): bool
{
return false;
}
public static function destroyOnClose(): bool
{
return true;
}
}
</code></pre>
<p>it's blade file (delete-contact.blade.php)</p>
<pre><code><x-modal formAction="delete">

Are you sure you wish to delete this contact?
</x-slot>
<x-slot name="buttons">

</x-jet-button>
<x-jet-button type="button" class="mx-2" wire:click="$emit('closeModal', ['contact_id' => $contact_id])">
{{ __('No') }}
</x-jet-button>
</x-slot>
</x-modal>
</code></pre>
<p>The component to render the table:
ContactsTable.php</p>
<pre><code><?php

Django template won't let my datetime field pop up or open
|
<p>I've been experiencing a weird error when using django for loop template, whenever I use my "{% for groups in groups %}" for loop, my datetime field won't open, however when I try to use other context for my loop, it just works. I also just simply copy pasted this modal from my other html page since it has the same function. Already checked if there are any conflicts with id and other loops. Also tried inspecting element on the modal's button, and it shows the correct group id. I have been using the same loop for other functions in this html page and it seems to be working fine as well. Any idea on how to debug this issue?</p>

How to pass a button array into a function

<p>I'm trying to create a function that will send a serial string to a com port and change colors every time a button is pressed. </p>
<p>I have figured out how to do this with one button, but now I want to make an array of 140 buttons that can all be passed through this function. </p>

Strange white rectangle boxes that appear and disappear on website
|
<p>There are strange white rectangle boxes that appear and disappear in a chatroom that I created. They randomly appear at the bottom and right side of the chatroom behind the scroll bars, and I am unsure of the cause. Possibly incorrect CSS of HTML? Inspecting the page does me no justice because the boxes do not show up in my code however they randomly appear whenever they want to.</p>
<p>My site is currently running locally. And perhaps this is a localhost/glitch phenomenon, and possibly the bug will simply go away when I launch the site. However I don't want to risk that, so can someone shed some light on this issue? I need to know whats causing this. Here is what it looks like:</p>
<p><a href="https://i.stack.imgur.com/lCJra.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/lCJra.png" alt="enter image description here" /></a></p>
<p><a href="https://i.stack.imgur.com/bI32q.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/bI32q.png" alt="enter image description here" /></a></p>
<p>Usually, the scroll bar on the right is black/almost translucent. At the bottom, there is absolutely no need to scroll right or left. However like I said the rectangle just appears.</p>
<p>Should I just change the scroll bar background color? Here is what my HTML looks like:</p>
<pre><code> <div id="chatArea" class="chatroom">
<div id=box class="lemoncakeleft">
<div class="chat" id="chat"></div>
</div>
<form id="messageForm">
<div class="form-group">
<input type="text" required="required" placeholder="Enter your message here" class="enter-message" id="message"/>
</div>
<input class="chatbutton" type="submit" value="Send"/>
</form>
</div>
</code></pre>
<p>I doubt the issue has to do with the input, where I type and send a message. So here is the css for the div <code>id="box"</code></p>
<pre><code>#box {
height: 556px;
width: 313px;
color: #E8E8E8;
text-shadow: 1px 1px 1px rgba(0,0,0,0.3);
word-wrap: break-word;
overflow: scroll;
overflow-y: auto;
}
</code></pre>
<p>I think it has to do with the <code>overflow</code> properties. Which is disappointing because i need those properties for the chat to function appropriately. Also, when viewing the site on my tablet and cell phone, the rectangles are not there. So what exactly is the issue?</p>
<p>Any suggestions or advice is appreciated. Thank you in advance.</p>

Onsen UI - Toolbar is not fixed to top on Cordova WP Universal App
|
<p>I am developing a cordova application with onsen ui.</p>
<p>I already found some problems that occur only on windows phone (i assume that this is the case because wp is not supported for such a long time)
. But there is 1 problem that i really need to fix.It seems that the ons-toolbar element is not fixed to the top in windows phone. If i scroll down, the toolbar also moves with the content. This doesn't happen on android.</p>
<p>Thats how i build up my page (the following code is inside an ons-sliding-menu):</p>
<pre><code><ons-page ng-controller="findUsersController">
<ons-toolbar fixed-style>
<div class="left">
<ons-toolbar-button ng-click="menu.toggleMenu()">
<ons-icon icon="fa-bars">
</ons-toolbar-button>
</div>
<!--<div class="left"><ons-back-button ons-if-platform="ios">Back</ons-back-button></div>-->
<div class="center"><h3 style="display:inline;">Connect<span style="color:cornflowerblue;">Us</span></h3></div>
</ons-toolbar>
<ons-pull-hook ng-action="findUsers($done)" var="loader">
<span ng-switch="loader.getCurrentState()">
<span ng-switch-when="initial"><ons-icon size="35px" icon="ion-arrow-down-a"></ons-icon> Pull down to refresh</span>
<span ng-switch-when="preaction"><ons-icon size="35px" icon="ion-arrow-up-a"></ons-icon> Release to refresh</span>
<span ng-switch-when="action"><ons-icon size="35px" spin="true" icon="ion-load-d"></ons-icon> Loading data...</span>
</span>
</ons-pull-hook>
<ons-list>
<ons-list-item ng-show="users.length === 0">
<div class="info">
Pull down to refresh
</div>
</ons-list-item>
<ons-list-item class="item" ng-repeat="user in users">
<ons-row>
<ons-col width="80px">
<img ng-src="http://lorempixel.com/60/60/?{{user.rand}}" class="item-thum" />
</ons-col>
<ons-col>
<p class="item-desc">{{ user.username }}</p>
</ons-col>
</ons-row>
</ons-list-item>
</ons-list>
</ons-page>
</code></pre>
<p>Initially everything shows up correct, but when i pull down to refresh, the toolbar moves down as well and the ons-pull-hook doesn't react. How can this be? i mean the toolbar is in no scrollable element.</p>
<p>Is there anyone who has an idea how to fix this problem?</p>

Get and store all changed values in data
|
<p>I am trying to create an "activity log" type thing on my server. I am using Angular and Mongoose on a node server. What I am trying to achieve is compare the request body with data stored in the DB by doing a deep diff.</p>
<p>So, whenever an API is hit, I am running this function:</p>
<pre><code>createActivityInformation(currentObject, updatedObject) {
let information = [];
function getChangedItem(currentItem, updatedItem, key, prop){
if(!currentItem || !updatedItem) return
// IF OBJECTS
if(typeof(updatedItem) === "object" && !Array.isArray(updatedItem)){
for(let prop in updatedItem){
getChangedItem(currentItem[prop], updatedItem[prop], key, prop)
}
}
else if(Array.isArray(updatedItem)){
}
else{
if(key != 'updatedAt' && (currentItem && updatedItem) && (currentItem.toString() !== updatedItem.toString())){
// CHECK FOR DATE - THIS IS ADDED BECAUSE DATES ARE COMPARED DIFFERENT THAN TO STRINGS
if(currentItem instanceof Date && !isNaN(currentItem)){
if(new Date(currentItem).getTime() != new Date(updatedItem).getTime()){
information.push({
'changeFrom': { key: key, value: currentItem, prop: prop},
'changeTo': { key: key, value: updatedItem, prop: prop}
})
}
} else {
information.push({
'changeFrom': { key: key, value: currentItem, prop: prop},
'changeTo': { key: key, value: updatedItem, prop: prop}
})
}
}
}
}
for(let key in updatedObject){
getChangedItem(currentObject[key], updatedObject[key], key)
}
return information;
}
</code></pre>
<p>Essentially what I am trying to do is store the original data, and the changed data. But I cannot seem to get it to work perfectly. The method is supposed to do a deep diff to compare everything, but also exclude some fields, like for instance <code>updatedAt</code>, or <code>_id</code>.</p>
<p>I took a look at the npm package <code>deep-diff</code>, but that did not work. That even compares the mongoose wrappers, but also compares for instance strings with booleans which then gets returned. But I also want to save the current data as well as the updated data.</p>
<p>Is there maybe something else I can look at that might solve my problem?</p>
<p><strong>EDIT</strong>
Normal objects, strings, and numbers are fine. But nested objects, arrays and booleans seem to be giving me a hard time.</p>
<p>here is a fiddle:

React Native how to mock PixelRatio on 1 specific test
|
<p>I am having trouble testing my snapshot in react-native, to be more specific it's the PixelRatio I am having troubles with.</p>
<p>Code speaks more than words - I've simplified the code and removed all the noise:</p>
<p><strong>The component:</strong></p>
<pre><code>const Slide = (props) => (
<Image
source={props.source}
style={PixelRatio.get() === 2 ?
{ backgroundColor: 'red' } :
{ backgroundCoor: 'green' }}
/>
);
</code></pre>
<p><strong>The Snapshot test</strong>:</p>
<pre><code>import { Platform } from 'react-native';
describe('When loading the Slide component', () => {
it('should render correctly on ios', () => {
Platform.OS = 'ios';
const tree = renderer.create(
<Provider store={store}>
<Slide />
</Provider>,
).toJSON();
expect(tree).toMatchSnapshot();
});
describe('on devices with a pixelRatio of 2', () => {
it('it should render correctly', () => {
jest.mock('PixelRatio', () => ({
get: () => 2,
roundToNearestPixel: jest.fn(),
}));
const tree = renderer.create(
<Provider store={store}>
<Slide />
</Provider>,
).toJSON();
expect(tree).toMatchSnapshot();
});
});
});
</code></pre>
<p>But this doesn't work and after some digging I found a <a href="https://github.com/facebook/jest/issues/2582" rel="nofollow noreferrer">bug on github</a> that was already resolved - apparently you need to use <a href="https://github.com/facebook/jest/issues/2582#issuecomment-284514827" rel="nofollow noreferrer">beforeEach</a>. But that seems also not to be working or I am doing it wrong?</p>
<p><strong>The Snapshot test with the suggested solution of github</strong>:</p>
<pre><code>import { Platform } from 'react-native';
describe('When loading the Slide component', () => {
it('should render correctly on ios', () => {
Platform.OS = 'ios';
const tree = renderer.create(
<Provider store={store}>
<Slide />
</Provider>,
).toJSON();
expect(tree).toMatchSnapshot();
});
describe('on devices with a pixelRatio of 2', () => {
it('it should render correctly', () => {
beforeEach(() => {
jest.mock(pxlr, () => ({
get: () => 2,
roundToNearestPixel: jest.fn(),
}));
const pxlr = require('react-native').PixelRatio;
}
const tree = renderer.create(
<Provider store={store}>
<Slide />
</Provider>,
).toJSON();
expect(tree).toMatchSnapshot();
});
});
});

Inserting new record from AngularJS using Web API
|
<p>Hi I'm a newbie in web development and I'm having some trouble in inserting new data in my database.</p>
<p>First, there's an error in dbcontext.Tbl_Articles.Add(adto);
It says, cannot convert WebAPI.Models.Articles to WebAPI.DataLayer.Tbl_Articles</p>
<p>Another thing is, whenever I run my Web API, it says something like this - {"Message":"The requested resource does not support http method 'GET'."}
script file:</p>
<pre><code>$scope.AddArticle = function ()
{
var data =
{
Category: $scope.Category,
IsCarousel: $scope.IsCarousel,
IsImportant: $scope.IsImportant,
HeaderImage: $scope.HeaderImage,
Title: $scope.Title,
ByLine: $scope.ByLine,
Content: $scope.Content,
Author: $scope.Author,
PublishStartDate: $scope.PublishStartDate_date + " " + $scope.PublishStartDate_time + $scope.PublishStartDate_time_ext,
PublishEndDate: $scope.PublishEndDate_date + " " + $scope.PublishEndDate_time + $scope.PublishEndDate_time_ext
};
$http(
{
method: 'POST',
url: 'http://project-aphrodite-uat-service.azurewebsites.net/api/articles/createarticle',
data: JSON.stringify(data)
})
.then(function successCallback(response)
{
console.log(response);
},
function errorCallback(response)
{
console.log("error" + response);
});
};
</code></pre>
<p>ArticlesController.cs:</p>
<pre><code> [HttpPost]
[Route("api/articles/createarticle")]
public Articles CreateArticle(Articles obj)
{
DataLayer.DataLayer dl = new DataLayer.DataLayer();
dl.CreateArticle(obj);
return obj;
}
</code></pre>
<p>DataLayer.cs:</p>
<pre><code> public string CreateArticle(Articles obj)
{
var adto = new Articles();
adto.Category = obj.Category;
adto.IsCarousel = obj.IsCarousel;
adto.IsImportant = obj.IsImportant;
adto.HeaderImage = obj.HeaderImage;
adto.Title = obj.Title;
adto.ByLine = obj.ByLine;
adto.Content = obj.Content;
adto.Author = obj.Author;
adto.PublishStartDate = obj.PublishStartDate;
adto.PublishEndDate = obj.PublishEndDate;
using (ArticleEntities dbcontext = new ArticleEntities())
{
dbcontext.Tbl_Articles.Add(adto);
dbcontext.SaveChanges();
return "test";
}
}
</code></pre>
<p>I hope someone could help me fix these. Thankie so much!</p>

Token authorization in swagger in ASP.NET
|
<p>I am documenting the API of my application through Swagger, which works with validation through a session token, that is, through a username and password a token is generated for a certain time that allows the user to navigate the site. What I need is for swagger to capture this session token and place it in the header of the requests for the rest of the API methods automatically, the only thing I could achieve so far is to pass the token as a parameter, but doing it manually. The idea is to make it automatic. I leave the configuration of SwaggerConfig.cs that I carry for now.</p>
<pre class="lang-cs prettyprint-override"><code>public class SwaggerConfig
{
public static void Register()
{
var thisAssembly = typeof(SwaggerConfig).Assembly;
GlobalConfiguration.Configuration
// HABILITAMOS SWAGGER.
.EnableSwagger(c =>
{
var baseDirectory = AppDomain.CurrentDomain.BaseDirectory + @"\bin\";
var commentsFileName = Assembly.GetExecutingAssembly().GetName().Name + ".xml";
var commentsFile = Path.Combine(baseDirectory, commentsFileName);
c.SingleApiVersion("v1", "API");
c.OperationFilter<AddRequiredHeaderParameter>();
c.PrettyPrint();
c.ApiKey("apikey")
.Description("API Key Authentication")
.Name("Bearer")
.In("header");
c.IgnoreObsoleteActions();
c.IgnoreObsoleteProperties();
c.DescribeAllEnumsAsStrings();
.EnableSwaggerUi(c =>
{ c.DocumentTitle("Documentación API");
c.EnableApiKeySupport("apikey", "header");
});
}
}
</code></pre>
<p>In turn, add a class to validate the application from where it is made on request</p>
<pre class="lang-cs prettyprint-override"><code>public class AddRequiredHeaderParameter : IOperationFilter
{
public void Apply(Swashbuckle.Swagger.Operation operation, SchemaRegistry schemaRegistry, ApiDescription apiDescription)
{
if (operation.parameters == null)
operation.parameters = new List<Parameter>();
operation.parameters.Add(new Parameter
{
name = "AuthorizedClient",
@in = "header",
type = "intenger",
description = "Aplicacion",
required = true,
@default = axaxax
});
operation.parameters.Add(new Parameter
{
name = "ClientKey",
@in = "header",
type = "string",
description = "Cliente",
required = true,
@default = "bxbxbx"
});
operation.parameters.Add(new Parameter
{
name = "Authorization",
@in = "header",
type = "apikey",
description = "Token de sesión",
});
}
}

Trying to understand the use of the populate method
|
<p>I see that one way we use populate is to put one document from another collection into a "parent" collection. I was just going through <a href="https://stackoverflow.com/questions/34984199/why-wont-my-refs-populate-documents">this</a> question and I was hoping someone could explain the answer to me better. And show me a practical use. Here is an example from the answer.</p>
<pre><code>var PersonSchema = new mongoose.Schema({
t: String
}, {collection: 'persons'});
var User = mongoose.model('User', PersonSchema.extend({
_id: String,
name: String
}));
var ParentSchema = new mongoose.Schema({
s: String
}, {collection: 'parent'});
var Like = mongoose.model('Like', ParentSchema.extend({
_id: String,
user_id: {
type: String,
ref: 'User'
}
}));
</code></pre>
<p>Insert Data into DB,</p>
<pre><code>var user = new User({
t: 't1',
_id: '1234567',
name: 'test'
});
var like = new Like({
s: 's1',
_id: '23456789',
});
user.save(function(err, u){
if(err)
console.log(err);
else {
like.user_id = u._id;
console.log(like);
like.save(function(err) {
if (err)
console.log(err);
else
console.log('save like and user....');
});
}
});
</code></pre>
<p>Query by</p>
<pre><code>Like.findOne({}).populate('user_id').exec(function(err, doc) {
if (err)
console.log(err);
else
console.log(doc);
});
</code></pre>
<p>And the result is</p>
<pre><code>{ _id: '23456789',
__t: 'Like',
user_id: { _id: '1234567', __t: 'User', t: 't1', name: 'test', __v: 0 },
s: 's1',
__v: 0 }
</code></pre>
<p>QUESTION </p>
<ol>
<li>where does <code>__t: 'User'</code> come from?</li>
<li>I was thinking that using populate() or ref that would separate the collections but it looks like at the end the like collection has the users document in it. I think I wanted to use populate so I could make a document smaller.
3.Also if someone really wanted to help explain this to me I have an example that I have been trying to do and I don't know if I should use populate but if I should it would be great if you show me how. Here is the example.</li>
</ol>
<p>You have </p>
<ol>
<li>doctors </li>
<li>patients </li>
<li>information about the practice</li>
</ol>
<p>There could be like a 1000 doctors and lots of patients for each doctor. and the information will be about their practice(like how many employees they have). so I feel that there should be a separation of concern.(one reason is to prevent a single document for a patient from getting to big). So If we're going with the populate method If you could explain how to set it up for this case. I guess I could have a doctor as a parent and a child refs for patients and another child refs for information about practice. so maybe there should be an array of objectId for the patients and an array for Other information</p>
