74,228,635 | <p>In an endeavor to write cleaner code I'm (likely over-)using <code>enums</code>, like so:</p>
<pre><code>enum class SoundFileCode : char {
PC_STARTUP = '1', // probably never used
LOADING_READY = '2',
VOICE_RECOGNITION_ON = '3',
VOICE_RECOGNITION_OFF = '4',
DISPENSING = '5'
};
</code></pre>
<p>I'd like to be able to pass that value to a function in a nice clean way (preferably without having to cast anything to make it a cleaner API):</p>
<p><code>sendRemoteAudioMessage(SoundFileCode::LOADING_READY);</code></p>
<p>Here's the function signature:
<code>void sendRemoteAudioMessage(char audioCode){ }</code></p>
<p>I see you shaking your head. You already know the error I'm going to get: <code>Compilation error: cannot convert 'SoundFileCode' to 'char' for argument '1' to 'void sendRemoteAudioMessage(char)'</code></p>
<p>My goals are:</p>
<ol>
<li>To make it easy for code completion to suggest these hard-coded constant values</li>
<li>To be able to reuse the same names, but keep them namespaced cleanly within their own enum</li>
<li>To make it easy for a programmer to just select a code and pass it to the function without thinking too hard about it.</li>
</ol>
<p>If enums won't foot the bill here, what's a good approach? Creating a class with some static constants? (this is likely how I'd approach it in PHP / Java)</p>
<p><strong>UPDATE</strong></p>
<p>The following (if somewhat verbose) approach compiles and runs fine. Is there a superior approach?</p>
<pre><code>class SoundFileCode {
public :
static const char PC_STARTUP = '1';
static const char LOADING_READY = '2';
static const char VOICE_RECOGNITION_ON = '3';
static const char VOICE_RECOGNITION_OFF = '4';
static const char DISPENSING = '5';
};
</code></pre>

<p>I commented out one portion of the Set the outputs step and updated it to $GITHUB_OUTPUT. However, when the job runs the flow_changed output is not set. I cant post images, but if I look at the complete job section after the action runs with $GITHUB_OUTPUT flow_changed is not set. It is set when I use the old set-output command.</p>

74,228,654 | <p>I'm looking to generate popover highlight tags on data that I've gotten from a query. Currently, I've tried finding substrings wrapped in curly braces within the text, then replacing them with components, but I can't figure out how to get Vue to render & mount the new components</p>
<p>Example text:</p>
<pre class="lang-markdown prettyprint-override"><code>Lorem {ipsum} dolor sit amet, consectetur {adipiscing} elit, sed do eiusmod tempor incididunt
</code></pre>
<p>I've created a fairly simple regex to find and grab text wrapped in curly braces:</p>
<pre><code>\{(.[^{}]*)\}
</code></pre>
<p>And this is the code I've tried so far:</p>
<pre><code><template>
<span v-html="paragraphText"></span>
</template>
<script lang="ts">
import {MyComponent} from '#components';
export default defineComponent({
data () {
return {
paragraphText: '',
}
},
created () {
const re = /\{(.[^{}]*)\}/g;
let newText = `${this.text}`;
let match: RegExpExecArray;
do {
match = re.exec(newText);
if (match) {
newText = newText.replace(
match[0],
`<MyComponent ref='${match[1]}' style='font-weight:bold;'>${match[1]}</MyComponent>`
);
}
} while (match);
this.paragraphText = newText;
},
components: {
MyComponent,
}
})
</script>
</code></pre>
<p>I'm well aware that <code>v-html</code> won't render components to avoid XSS attacks, but this is mostly just to show what I'm trying to achieve.</p>
<p>My reasoning behind having a component behind each one, is that I want the component to make a web request on hover, to grab some additional information about the word being highlighted.</p>
<p>I'm looking for the cleanest and/or most efficient solution possible - it doesn't have to be Options API</p>

74,228,659 | <p>I'm working on a project where I have to give a background-image a full width. The image should become larger as I make the screen larger, and smaller as I make the screen smaller.</p>
<p>This is my code at the moment. It's a footer decoration:</p>
<pre><code>.footerDeco {
background-image: url(../resources/image_geometry_2.svg);
background-repeat: no-repeat;
height: 160px;
background-size: cover;
}
</code></pre>
<p>The background-size: cover makes the image adapt to full width, but the height of the image remains 160px no matter what. If I make the height larger, then it's a problem because it doesn't shrink back proportionally as the screen becomes smaller.</p>
<p>I have tried giving it a height auto or a height 100% expecting the height to change proportionally to the width. (I do understand this height is the height of the footer container, but I don't know how to change it otherwise).</p>
<p>I know it would be much easier to use an img tag. But the demands of the project and good practice insist that since this is a decoration, I should use the background-image property. Is it possible? Thanks!</p>
<p>P.S.: There are similar questions that have been answered here, but none of them (as far as I can tell) solve the problem of the image resizing past the constant container height of 16px.</p>

74,228,733 | <p>I think dart formatter is not working right. As an example:</p>
<p><code>controller2.animateToPage(frameworksPage, duration: const Duration(milliseconds: 480), curve: Curves.fastOutSlowIn);</code></p>
<p>formats as:</p>
<pre><code>controller2.animateToPage(
frameworksPage,
duration: const Duration(
milliseconds: 480),
curve: Curves.fastOutSlowIn);
</code></pre>
<p>and it gets even worse when it gets to if statements.
Is there a solution for this bs?</p>

74,228,860 | <p>I want to reshape the flattened channels array of audio to a 4D array(because audio has 4 channels). Reshape example is below:</p>
<p>Input example: [a1,b1,c1,d1,a2,b2,c2,d2,...]</p>
<p>Output 4D array: [[a1,a2,...], [b1,b2,...], [c1,c2,...], [d1,d2,...]]</p>
<p>Each subarray of the 4D array must be one of the channels of audio.
How can I do it in the fastest way?</p>

74,228,902 | <p>I have 2 go files:</p>
<pre><code>main.go
otherFile.go
</code></pre>
<p>Inside of 'main.go' I have a 'main' function and I can call it from the command line like this:</p>
<pre><code>go run main.go
</code></pre>
<p>So far so good.</p>
<p>Inside of 'otherFile' I can't have another 'main' function so I have a function called 'otherFunction'.</p>
<p>How can I call this function in 'otherFile.go' from the command line, similarly to how I did 'go run main.go'?</p>
<p>I don't necessarily want main.go to run, or call 'otherFunction' from 'main.go' by importing it, etc.</p>
<p>Is this possible or am I thinking about it in the wrong way? I am new to Go so still trying to figure out some of the basic concepts.</p>
<p>Thanks.</p>

74,228,918 | <p>I have the following dilemma. I am trying to pickle and then unpickle a numpy array that represents an image.</p>
<p>Executing this code:</p>
<pre><code>a1 = np.zeros((1080, 1920, 3), dtype=np.uint8)
print(sys.getsizeof(a1), a1.shape)
a2 = pickle.dumps(a1)
print(sys.getsizeof(a2), type(a2))
a3 = pickle.loads(a2)
print(sys.getsizeof(a3), a3.shape)
</code></pre>
<p>Produces this output:</p>
<pre><code>6220928 (1080, 1920, 3)
6220995 <class 'bytes'>
128 (1080, 1920, 3)
</code></pre>
<p>Now, <code>a1</code> is thus around 6 MB, <code>a2</code> is the pickle representation of <code>a1</code> and is a bit longer but still roughly the same. And then I try to unpickle <code>a2</code> and I get... something obviously not right.</p>
<p><code>a3</code> looks fine, i can call methods, I can assign values to it's cells etc.</p>
<p>The result is the same if I replace pickle calls with <code>a1.dumps</code> and <code>np.loads</code> since these just call pickle.</p>
<p>So what exactly is the deal with the weird size?</p>

74,228,936 | <p>I want to make responsive vertical menu with icons, that would shrink with transition (fade in to left) when screen width is to small. It would look like this - normal menu:</p>
<ul>
<li>(icon1) Position1</li>
<li>(icon2) Position2</li>
<li>(icon3) Position3</li>
</ul>
<p>and after shrinking window to let's say 800px it should fade into the left and look like this:</p>
<ul>
<li>(icon1)</li>
<li>(icon2)</li>
<li>(icon3)</li>
</ul>
<p>How do I make such thing using only HTML and CSS?</p>

74,229,004 | <p>I have two array lists, one for employees, another for their availabilities. The arrays are of different size. I don't see the problem with that when I'm using the array of the larger size in <code>getItemCount()</code>:</p>
<pre><code>@Override
public int getItemCount() {

<p>I set recycler view to get all employee items, however my availability is a shorter list. If I have 6 availability's and 12 employees everything goes smooth on the first page as it only shows the 6 employees. But when I scroll down it will crash as there is a 7th employee but no 7th availability.</p>

<p><code>availability</code> table has 2 values and <code>employees</code> 7. In <code>getItemCount</code> I'm using the size of my employee table.

<blockquote>
<p>java.lang.IndexOutOfBoundsException: Index: 2, Size: 2</p>

<p>Adding an availability for every employee would defeat the purpose of my project. How to solve this with the use of two separate arrays of different size?</p>

Then here is the driver (the driver was provided to me by a third party so it must work as it is presented and cannot be changed)</p>
<p>`</p>
<pre><code>import java.util.Scanner;
public class MemoryLaneDriver
{
public static void main(String[] args)
{
String message = "Welcome to Memory Lane!" + "\n" +
"Choose two indexes to reveal the corresponding dominoes." + "\n" +
"If the dominoes match, they stay revealed." + "\n" +
"Reveal all the dominoes to win the game!" + "\n";
System.out.println(message);
Scanner input = new Scanner(System.in);
MemoryLane game = new MemoryLane(2);
long start = System.currentTimeMillis();
while(!game.gameOver())
{
System.out.println(game);
System.out.print("First: ");
int first = input.nextInt();
System.out.print("Second: ");
int second = input.nextInt();
game.guess(first, second);
System.out.println(game.peek(first, second) + "\n");
}
long stop = System.currentTimeMillis();
long elapsed = (stop - start) / 1000;
System.out.println(game);
System.out.println("\nYou win!");
System.out.println("Total time: " + elapsed + "s");
}
}
</code></pre>
<p>`</p>
<p>I have tried using the methods in Domino like setRevealed and isRevealed in the guess method (for example when i try board.setRevealed = true or board.isRevealed = true), but it wont work and turns up red in IntelliJ. I can also not use any Stringbuilder uses (such as append) because it is outside of what has been covered in class.</p>
<p>When I say the game is working correctly, I mean that it outputs my choices like:</p>
<p>`</p>
<pre><code>Welcome to Memory Lane!
Choose two indexes to reveal the corresponding dominoes.
If the dominoes match, they stay revealed.
Reveal all the dominoes to win the game!
[ ] [ ] [ ] [ ] [ ] [ ]

[ ] [ ] [ ] [ ] [ ] [ ]
First:
</code></pre>
<p>`</p>
<p>However as you can see it is not revealing the correct guess, and even if I guess all of the Dominos correctly the game does not end.</p>

74,229,053 | <p>can you tell me how to have the following code make multiple images that are layered over one another? Like if I wanted to sometimes have this code post an image1.png with image2.png overlayed over it, but with other if statements true it would post image1.png with image3.png overlayed over it?</p>
<pre><code>// create the images:
var container = document.getElementById("container");
for (var i=0;i<3;i++) {
var img = document.createElement("img");
img.src="https://via.placeholder.com/350x150";
img.classList.add("img");
container.appendChild(img);
}
document.querySelectorAll(".img").forEach(function(img,i) {
img.id="image--"+i; // makes more sense to do that in the creation part too
})
document.getElementById('image--1').src = "https://via.placeholder.com/350x150?text=Image1";
<div id="container"></div>
</code></pre>
<p>I tried this code but I couldn't figure out a way to make images that overlay one another, it just posts them one after another.</p>
<p>I want to keep using this code because it always posts directly under the most recently created image, making a column of images on your webpage which is exactly the aesthetic I'm looking for.</p>

74,229,062 | <p>When I am requesting data using route params <code>paramMap</code> I'm able to get everything working great when it's a single argument. For example, <code>foo.getThing(id)</code>.</p>
<p>I am struggling how to "observe" multiple arguments though. I need both, my <code>organizationId</code> <em>and</em> my <code>locationId</code> to look up a location.</p>
<p>I've been reading through several tutorials and perhaps ForkJoin may be what I need, but all I have seen so far is getting the initial request from something that doesn't take arguments. For example, <code>foo.getStuff()</code> not <code>foo.getThing(id)</code></p>
<pre><code>// settings.component.ts
private organizationId!: string;
private locationId!: string;
private organizationId$ = this.activatedRoute.paramMap.pipe(
tap((params) => {
this.organizationId = params.get('organizationId')!;
})
);
private locationId$ = this.activatedRoute.paramMap.pipe(
tap((params) => {
this.locationId = params.get('locationId')!;
})
);
public location$: Observable<ILocation> = this.locationId$.pipe(
switchMap(() =>
this.locationService.getLocation(this.organizationId, this.locationId)
)
);
</code></pre>
<p>When I am getting details about my organization, I can just subscribe to the <code>organizationId</code>. If that changes, the response updates accordingly.</p>
<p>I am trying to accomplish the same for my location. If the <code>organizationId</code> <em>or</em> <code>locationId</code> change, I'd like the pipe to re-run and get the correct data.</p>
<p>How can I subscribe to two different observables?</p>

74,229,070 | <p>I have a group of checkboxes with different values each. I want to assign their values in php variables which i'm going to send to database. The main problem is that i don't know how to check inside the php code if the values of selected items matching their default values which i setup in the html (apple == apple, samsung == samsung) and so on. This is because someone can just change the input value inside the console and insert whatever he likes in my DB. Any ideas how i can sort this out. Many thanks!</p>

74,229,102 | <p>I will almost always be computing my memory needs in the unit of bytes. I wouldn't know how large a "page" is, I had to look it up (<a href="https://developer.mozilla.org/en-US/docs/WebAssembly/JavaScript_interface/Memory" rel="nofollow noreferrer">MDN says</a> it's 64KB). It's not obvious that the size of a page even <em>should</em> be a fixed (documentable) platform-independent constant. I'm unable to source a reason or even an attestation for the page size being that in MDN's spec link.</p>
<p>I can only think of really bad reasons for it to be this way and I want to figure out whether it really is that bad.</p>

74,229,197 | <p>i want to make a program which related to this question:</p>
<blockquote>
<p>An integer that can be expressed as the square of another integer is called a perfect square, such as 4,9,16,25, etc. Write a progran that checks if a number is a perfect square.</p>
</blockquote>
<p>I did built something goes like:</p>
<pre class="lang-java prettyprint-override"><code>import java.util.Scanner;
class Q3{
public static void main(String[] args){
Scanner sc = new Scanner(System.in);
int num = 0;
int a = 0;
System.out.println("Type a number to check if it has square");
num = sc.nextInt();
for(a = 1;a<num;a++){ }
if (a*a == num){
System.out.println("Ok");
break;
}
else if (a*a != num){
System.out.println("Not ok");
}
}
}
</code></pre>
<p>So it doesn’t give what i want when i run it. What should i change or add ?</p>

74,229,198 | <p>I'm writing a subclass that encapsulates multiple objects of the parent class so I can call functions sort-of like a vector, something like this:</p>
<pre class="lang-perl prettyprint-override"><code>package OriginalClass;
sub new { return bless {bar => 123}, 'OriginalClass' }
sub foo { return shift->{bar}; }
1;
package NewClass;
use parent OriginalClass;
# Return a blessed arrayref of "OriginalClass" objects.
# new() would be called NewClass->new(OriginalClass->new(), ...)
sub new {
my $class = shift;
return bless \@_, 'NewClass';
}
# Vectorized foo(), returns a list of SUPER::foo() results:
sub foo
{
my $self = shift;
my @ret;
push @ret, $_->SUPER::foo() foreach @$self;
return @ret;
}
1;
</code></pre>
<p>I don't want to write a new vectorized function in <code>NewClass</code> for each function in <code>OriginalClass</code>, particularly for when <code>OriginalClass</code> adds new functions to be maintained (vectorized) in <code>NewClass</code>.</p>
<p><strong>Question:</strong></p>
<p>As I understand <code>AUTOLOAD</code> is slow, so is there a way to vectorize calls <code>OriginalClass</code> via something like <code>NewClass</code> without <code>AUTOLOAD</code>?</p>

74,229,201 | <p>This code gives me the output: <code>The names found are: ['Alba', 'Dawson', 'Oliver']</code></p>
<p>I would need to remove the brackets and quotes, and always print "and" before the last name (the number of names can be variable and for example I could have 3,4,5,6 names), so I would need this output:</p>
<pre><code>The names found are: Alba, Dawson and Oliver
</code></pre>
<p>Code</p>
<pre><code>name = "Alba, Dawson, Oliver"
names = name.split(', ')
print("The names found are: ", names)
</code></pre>
<p>How can I achieve this?</p>

74,229,207 | <p>I have successfully implemented the thread pool from <a href="https://stackoverflow.com/a/32593825/12351436">an answer on Stack Overflow</a>, which helped me in speeding up my program. It uses a single <code>std::queue</code> to distribute jobs (<code>std::function<void()></code>) among multiple workers (<code>std::thread</code>s).</p>
<p>I wanted to improve on this. As I only need to run a limited set of functions, I planned to ditch the queue and to use variables instead. In other words, the <code>n</code>-th worker would do the <code>n</code>-th job from the <code>std::vector<std::function<void()>></code>. Unfortunately, my test app crashes with <code>Segmentation fault (core dumped)</code> and I could not realize my mistake so far.</p>
<p>Here is my ~minimal reproducible code, with the job of counting the odd elements in a vector. (Idea taken from <a href="https://youtu.be/WDIkqP4JbkE?t=551" rel="nofollow noreferrer">Scott Meyers: Cpu Caches and Why You Care</a>.)</p>

74,229,216 | <p>I have two apps. The first app launches the second app and should stop the second app after a time interval (currently 10 seconds) and then relaunch the app. Here is the code I have so far:</p>
<pre><code>package com.example.launch
import android.content.ActivityNotFoundException
import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle
import android.util.Log
class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
}
override fun onResume() {
super.onResume()
val launchIntent = packageManager.getLaunchIntentForPackage("com.example.secondapp")
while (true) {
if (launchIntent != null) {
try {
startActivityForResult(launchIntent, 1)
Log.d("", "Launching com.example.secondapp")
} catch (e: ActivityNotFoundException) {
Log.d("", "Failed to launch com.example.secondapp")
}
} else {
Log.d("", "Intent is null value.")
}
Thread.sleep(10000)
finishActivity(1)
}
}
}
</code></pre>
<p>On my android phone (Galaxy A12) the first app launches the second app but doesn't stop it. Here is some typical output from the first app.</p>
<pre><code>2022-10-28 00:17:58.127 21240-21240/com.example.launch D/: Launching com.example.secondapp
2022-10-28 00:18:08.140 21240-21240/com.example.launch D/: Launching com.example.secondapp
2022-10-28 00:18:18.150 21240-21240/com.example.launch D/: Launching com.example.secondapp
</code></pre>
<p>So it seems from the output that the first app believes it is successfully launching the second app every 10 seconds. This doesn't correspond with what I am seeing on the phone or in the log for the second app which is continuing to run without being stopped or relaunched.</p>
<p>Where am I going wrong? How can I fix this?</p>

74,229,326 | <p>If I use them both the same time (not sure if it's a good habit or not) in following example, what's the actual timeout?</p>
<pre><code>ExecutorService executorService = executorServiceFactory.createThreads(2);
List<Callable<T>> tasksList = new ArrayList<>();
tasksList.add(task1);
tasksList.add(task2);
executorService.invokeAll(taskList);
// get the result object with 5 minutes timeout
final task1 = tasksList.get(0).get(5, TimeUnit.MINUTES);
final task2 = tasksList.get(1).get(5, TimeUnit.MINUTES);
executorService.shutdown();
// set the timeout to 30 seconds for executor service
executorService.awaitTermination(30, TimeUnit.SECONDS);
</code></pre>
<p>In the above example, I want to get the result of the completable future (used in other places), if I place a 5 minutes timeout in the <code>get()</code> method, but I do shutdown the executor service and <code>awaitTermination</code> for 30 seconds, which time will take effect? Is it 30 seconds? Since it's shorter than 5 minutes?</p>

74,229,335 | <p>I am pretty new to python and coding. I am trying to write a code that will print out the total amount of each given wire type from a list of wires. This is a side project for work. I was able to come up with a code to sum up all of the wire for a user defined wire type. Now I would like to make another code that prints out the total of each wire type in the file.</p>
<p>This is the code that I came up with to sum up individual wire type as selected by the user.</p>

w = []
w1 = []
#opens the .TXT file
fhand = input('\nEnter Text File\n')
try:
if (len(fhand) <= 0):
fhand = 'test.txt'
fh = open(fhand)
except:
print('\nNo File Found:', fhand, '\n')
exit()
#prints out the possible wire types
for line in fh:
line = line.rstrip()
wtype.append(line) #needed for later in the code
line2 = line.split(',')[2]
if line2 not in w:
w.append(line2)
else:
continue
d1 = dict(enumerate(w))
print(d1)
#sums up the selected wire types total length from the given .TXT file
wire = int(input('\nEnter the number that is before the wire type you need:\n'))
for key, val in d1.items():
if key == wire:
for x in wtype:
x = x.split(',')
if x[2] == val:
w1.append(x[1])
else:
continue
s = [eval(i) for i in w1]
print('\nYour will need ', sum(s)/12, ' Feet of ', val, '.\n')
</code></pre>
<p>This is the <code>test.txt</code> file, the length is in inches and the converted to feet in the last line of the code <code>sum(s)/12</code>:</p>
<p>the column are WIRE, LENGTH, TYPE, QTY for this file.</p>

74,229,355 | <p>I am developing an application in Kotlin for Android 11. My app collects a log of sailing data from the boat instruments and internal GPS during a race.</p>
<p>I want to write a .csv file to some location where the User can access this using Windows File Explorer (connecting to the Android device with a USB cable) to copy and analyse the data in Windows.</p>
<p>I have been able to create and write .csv files to a subdirectory of Documents however if the User deletes the file using FileExplorer then Android 11 still reports that the file exists { filename.exists() returns true } when it doesn't, but worse won't delete what it thinks exists using { filename.delete() }, returns false for { filename.CanWrite() }, fails (returns false) to execute { filename.createNewFile()} and crashes if I try and write anything to the file.</p>
<p>How can I reliably provide the logged data to a User ???
Very happy to use any alternative approach that can get the log data to the User and not be damaged by File Explorer actions.</p>
<p>I successfully obtained User permission to write files to a subdirectory under Documents /storage/emulated/0/Documents/layline</p>
<p>The path to the Documents folder was obtained from:
Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOCUMENTS)</p>
<p>The Manifest contains:<br />
<code> <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> android:requestLegacyExternalStorage="true"</code></p>
<p>and I successfully verified the permissions with:
checkSelfPermission(Manifest.permission.READ_EXTERNAL_STORAGE) retuns 0
checkSelfPermission(Manifest.permission.WRITE_EXTERNAL_STORAGE) returns 0</p>
<p>I was able to read and write to a file OK until the file was deleted using Windows File Explorer.
The files are Read Only from Windows perspective and if the file is edited and saved to a separate location and then copied back to overwrite the original, the file system starts presenting [1], [2] etc suffixes and Android 11 can't seem to get back at the file (it thinks that a version exists but can't delete or write to it).</p>
<p>Uninstalling and reinstalling the app does not fix the problem. Android 11 still reports that the file exists, but can't write to it.<br />
filename.SetWritable() does not help (returns false).</p>
<p>Do I need to use All Files Access or Manage External Storage ?</p>

74,229,403 | <p>Would really appreciate if someone can weigh in on this :)</p>
<p>What Im trying to achieve is to grab a specific email from outlook with current date and specified subject. After this I want to copy the contents of the email (a table) to the active excel sheet.
Im already looping through a generic object.</p>
<pre><code>Sub Mail3()
Dim Folder As Outlook.MAPIFolder
Dim sFolders As Outlook.MAPIFolder
Dim MailBoxName As String, Pst_Folder_Name As String
Dim oMail As Object
Dim y As Long, x As Long
Dim olInsp As Outlook.Inspector
Dim wdDoc As Word.Document
Dim tb As Word.Table
Dim Myemail As String
Dim Atmt As Attachment
Dim irow As Integer
Dim oItem As Outlook.MailItem
Dim ns As Namespace
irow = 1
'set email date
Set ns = GetNamespace("MAPI")
Myemail = "abcd"
'Mailbox or PST Main Folder Name to set the name of the inbox - I have several mailboxes, needed to specify
MailBoxName = "myinbox"
'Mailbox Folder or PST Folder Name (As how it is displayed in your Outlook Session)
Pst_Folder_Name = "Inbox" 'Sample "Inbox" or "Sent Items"
'To direct to a Folder at a high level
Set Folder = Outlook.Session.Folders(MailBoxName).Folders(Pst_Folder_Name)
'copying the email contents into the refresh file
For Each oMail In Folder.Items
If oMail.Class = 43 Then
Set oMail = oItem
If oMail.Subject = Myemail And (Now() - oMail.ReceivedTime) < 1 Then
'oMail.SentOn = DateSerial(Year(Now), Month(Now), Day(Now)) Then
Application.ThisWorkbook.Worksheets("Sheet1").Range("B9").Value = oItem.HTMLBody
End If
End If
Next oMail
End Sub
</code></pre>
<p>Bare in my mind that Im learning VBA and this code isnt entirely my creation.</p>
<p>Edit:</p>
<p>Ok so ive changed a bunch of things.
This time using oMail as Object</p>
<p>Still getting an object not definined error
here
Application.ThisWorkbook.Worksheets("Sheet1").Range("B9").Value = oItem.HTMLBody</p>

74,229,442 | <p>I want to add a <code>strike-through</code> decoration to the <code>#text</code>-node-like children of a particular item we render using <a href="https://meliorence.github.io/react-native-render-html/docs/guides/custom-renderers" rel="nofollow noreferrer">custom rendering</a>.</p>
<p>But I'm not aware of any way to actually target the child <code>#text</code>-like-node and apply styles to it.</p>
<p>For example, we could wrap the <code>TChildrenRenderer</code> like below, but those styles will not be inherited by the <code>Text</code> component that <code>TChildrenRenderer</code> renders. So this works for some styles, like <code>lineDecorationType: 'line-through'</code>, but not for things like <code>color</code>.</p>
<pre class="lang-js prettyprint-override"><code><Text style={{ color: 'red' }}>
<TChildrenRenderer tchildren={tnode.children} />
</Text>
</code></pre>
<p>Is there any approach that would allow us to set <code>color</code> on the inner rendered text?</p>
<hr />
<p><strong>Edit</strong>: The method has to allow for conditional styling, so a top-level prop like <code>defaultTextProps</code> is out.</p>

74,229,459 | <p>I have a tricky situation.</p>
<p>I have a source dataset; it has data for four employees and their departments based on an effective date.</p>
<p>I need to convert this source dataset to the destination dataset.</p>
<p><a href="https://i.stack.imgur.com/NJsI7.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/NJsI7.png" alt="enter image description here" /></a></p>
<p>Both datasets are properly sorted by EmployeeName and EffectiveDate (ASC) order.</p>
<p>(Please see T-SQL scripts using temp table.)</p>
<pre><code>CREATE TABLE #source
(
EmployeeName varchar(100),
EffectiveDate date,
CurrentDepartment varchar(100)
);
INSERT INTO #source
VALUES
('Lisa','2017-06-25','Catering'),

SELECT *
FROM #source
ORDER BY EmployeeName, EffectiveDate
SELECT *
FROM #destination
ORDER BY EmployeeName, EffectiveDate
</code></pre>
<p>In the destination dataset, I need one new column called [PreviousNonNULLDepartmentIfAvailable].</p>
<p>What is the logic to derive this above new column?</p>
<p>I need to get each individual's most recent (previous) department; it is easy to use a LAG function to get the most recent (previous) department. See T-SQL code below:</p>
<pre><code>PreviousNonNULLDepartmentIfAvailable = LAG(CurrentDepartment) OVER(PARTITION BY EmployeeName ORDER BY EffectiveDate)
</code></pre>
<p>However, I need the most recent (previous) non-NULL department; if there is no such "most recent (previous) non-NULL" department value within the PARTITION of EmployeeName, then I need to show NULL.</p>
<p>I have tried <a href="https://www.mssqltips.com/sqlservertip/7379/last-non-null-value-set-of-sql-server-records/" rel="nofollow noreferrer">options</a> such as LAG, LAST_VALUE, IGNORE NULLS clause, UNBOUNDED PRECEDING clause. These options are close to what I need, but NOT exactly what I need.</p>
<p>Effectively, I need to get what a LAG function would perform; but the offset value for LAG function has to be dynamic, instead of a static value such as 1 or 2 or 3...; the LAG function needs to iterate (backwards) as many rows as needed to catch the most recent (previous) non-NULL department value, within a PARTITION of EmployeeName.</p>
<p>This said, the column [PreviousNonNULLDepartmentIfAvailable] can <strong>still</strong> have NULL values, if there is <strong>no</strong> such "most recent (previous) non-NULL" department value available within a PARTITION of EmployeeName.</p>
<p>Also, the first row based on ascending order of Effective Date of each partition of EmployeeName will always have NULL as its [PreviousNonNULLDepartmentIfAvailable] value (obviously). This is natural in the way LAG function works.</p>
<p>Any idea on how to convert the source dataset to destination dataset ?</p>

<p>Anyone with any experience using PDFTron tab view for multiple documents.</p>
<ol>
<li>Does each tab have a documentViewer or is this global and updated when the tab is changed.</li>

<pre><code>abs n | n >= 0 = n
| otherwise = -n
</code></pre>
<p>it basically says that function <code>abs</code> returns <code>n</code> if <code>n >= 0</code>, otherwise it returns <code>-n</code>.</p>
<p>In the book it says that the the standard prelude otherwise is defined like this: <code>otherwise = True</code>, why is that?</p>

74,229,649 | <p>I use <code>gq</code> to format my Go code. I set <code>formatprg=goimports</code>.
I want to execute <code>gq</code> on save automatically. I added this line in my vimrc:</p>
<pre><code>au BufWritePost *.go normal gggqG
</code></pre>
<p>This works great, but the one thing is, because of <code>G</code>, my cursor goes to the bottom line in the buffer when I save the file (by <code>:w</code>) .
I want to keep my cursor place after running <code>gq</code>. How can I do this?</p>
<p>I know some plugins enable to do this, but I prefer not using them.</p>

74,229,662 | <p>For example, I have 9 conditions lets say and i want to store the seed number within a loop that goes into the results list that contains con1-con9. In my actual code the seed number will be changing, but just have this here for simplicity.</p>
<pre><code>seed <- 500
for(x in 1:length(results)){
results$con1$seednum <- seed
}
</code></pre>
<p>I thought something like this, but does not seem to work.</p>
<pre><code>eval(parse(text= paste0("results$con", x)))$seednum <- 500
</code></pre>
<p>How can i have this such that the con1 will change to con2, con3...etc through the for loop and be able to store that seed value in each results$con1 through results$con9? I assume it has something to do with eval and parse while using the x index, but I am not sure how it can be done.</p>
<p>Thank you.</p>

74,229,729 | <p>I have a table with many categories
Currently, I am rendering them with tr tags, each category will be displayed in a child tag</p>

<p>Where did I go wrong or does someone have a better idea how to do this?
I have tried rendering a tr tag that will contain "parent" and "first child", "other children" will be rendered in the next tr, but this is very complicated, calculating rowspan is difficult.</p>
<p>I trying to find out the correct html table layout what I should to use to render table with nested categories</p>
<p>P/s: I am trying to render column by column (this makes it easier for us to gather data and load
Building data structures and load data onto tables with default rendering (line by line) is a nightmare for both the writer and the maintainer (in this case - nested categories)</p>

I can make an deep equal with a fixture. But I dont think that this would be the cleanest solution for assertin just 2 value's in a array.</p>

<p>child component</p>

<p>sorry for the bad code formatting.</p>
<p>This is a mock of what it looks like</p>
<p>this should give a somewhat clear understanding or image of the issue, i basically want to get all the <code>Amount</code> on the 4 render children, place it in an array and send it to the Parent component (so i can call a function that uses all the amount in an array as an argument)</p>
<p>i tried to set the values of the Child component to a state on context (it was wrong, it kept on pushing the latest field values that was edited, i am new to react so i didnt understand some of the things that were said about state lifting</p>

<p>I removed this permission from my app even removed plugin which used it but still got this rejection.
I checked all android manifest files, even all logs there is no REQUEST_INSTALL_PACKAGES permission</p>

74,229,953 | <p>As shown in the following react code snippet, I have a useEffect hook with a dependency 'fetchQuery'. The useEffect hook will execute if 'fetchQuery' variable changes. But right after execution of it, I want to clear the value (set to '') of that dependency variable 'fetchQuery' without triggering an infinite loop. Is there a way to do that?</p>
<pre><code>useEffect(() => {
// An async function to fetch some data
getDataModules(fetchQuery);
}, [fetchQuery]);
</code></pre>
<p>Since 'fetchQuery' is a state variable and is given as a dependency for this hook, simply clearing its value using <code>setFetchQuery('');</code> will trigger useEffect again, which I dont want.</p>

74,230,028 | <p>I'm working on an ASP.NET Core MVC application and I have a view who do a post request as:</p>
<pre><code> $.ajax({

success: function(r){
Swal.fire("Inactivated!", "Advertiser inactivated successfully", "success");

error: function (request) {
console.log(request.responseText)
Swal.fire("Error!", "Something went wrong, please try again`", "warning");

});
</code></pre>
<p>Controller:</p>
<pre><code>[HttpPost]
public async Task<JsonResult> ActiveAdvertiser(int id, bool isActive)
{
var advertiser = await _advertisersService.GetAdvertiserByAdvertiserIdAsync(id);
if (advertiser != null)
{
var model = AssingAdvertiserViewModel(advertiser, id);
model.IsActive = isActive;
var result = await _advertisersService.UpdateAdvertiserAsync(model, GetCurrentUserAsync().Id);
if (result != null)
{
return Json(new { result = "OK" });
}
}
return Json(new { result = "BadRequest" });
}
</code></pre>
<p>Post method services:</p>
<pre><code>public Task<Advertiser?> GetAdvertiserByAdvertiserIdAsync(int advertiserId)
{
return _db.Advertisers
.Include(a => a.Address)
.Include(pc => pc.PrimaryContact)
.Include(ac => ac.AlternateContact)
.FirstOrDefaultAsync(x => x.AdvertiserId == advertiserId);
}
private AdvertiserViewModel AssingAdvertiserViewModel(Advertiser advertiser, int id)
{
var model = new AdvertiserViewModel()
{
//Fill model here
};
return model;
}
public async Task<Advertiser?> UpdateAdvertiserAsync(AdvertiserViewModel model, int updatedById)
{
var advertiser = await GetAdvertiserByAdvertiserIdAsync(model.AdvertiserId);
if (advertiser is null)
return null;
advertiser.Name = model.Name;
// fill model here
await _db.SaveChangesAsync();
return advertiser;
}
</code></pre>
<p>The problem is I do the first request, and it returns Success with any issues, but if I try to do a second one, it throws an exception:</p>
<blockquote>
<p>System.InvalidOperationException: A second operation was started on
this context instance before a previous operation completed. This is
usually caused by different threads concurrently using the same
instance of DbContext.</p>
</blockquote>
<p>If I stop the project and run it again it works one time again and in the second time get the error again</p>
<p>I read about this issue in other questions, and apparently is because you don't use the await services, I check my code and almost everything uses await. Can someone see something that I don't see? Regards</p>

74,230,305 | <p>I am writing a code that asks for the users input for the number of rows and columns. When given the integer values, the program will print out the number of the row and the letter that will increment will be next to it, just like seat numbers in a theatre or stadium. What I am trying to do is to use a for loop and a while loop to try to split up the rows and numbers.</p>
<p>Here is an example (row is 2 and column is 3):</p>
<pre><code>1A 1B 1C
2A 2B 2C
</code></pre>
<p>However that did not work, what I have tried is to use a double for loop for the values but that didnt work. So I tried using a while loop to try and get the second row but didnt work. I can only get the first row to print out</p>
<p>Here is the code im working on:</p>
<pre><code>num_rows = int(input("Enter number of rows: "))
num_cols = int(input("Enter number of columns: "))
rangerows = num_rows + 1
rangecols = num_cols
colsnow = 0
rowsnow = 1
for i in range(1, num_rows):
while colsnow < rangecols:
print(f'{i}{chr(colsnow + 65)}', end=' ')
colsnow += 1
print()

74,230,459 | <p>Hey guys so I'm writing a code for text message abbreviations and these are the following criteria:</p>
<ul>
<li>Spaces are maintained, and each word is encoded individually. A word is a consecutive string of alphabetic characters.</li>
<li>If the word is composed only of vowels, it is written exactly as in the original message.</li>
<li>If the word has at least one consonant, write only the consonants that do not have another consonant immediately before them. Do not write any vowels.</li>
<li>The letters considered vowels in these rules are 'a', 'e', 'i', 'o' and 'u'. All other letters are considered consonants.</li>
</ul>
<p>I have written a code and checked it but it is failing for the condition where if the word is composed only of vowels, it is written exactly as in the original message. My code currently is taking out all of the vowels. Like for this example, "aeiou bcdfghjklmnpqrstvwxyz" the code should return "aeiou b"
I tried using another helper function to determine when a word is all vowels but it isn't working. Any suggestions on how to implement something that could make this work? Thanks!</p>
<pre><code>def Vowel(x):
vowels = "a" "e" "i" "o" "u"
value = 0
for ch in x:
if x == vowels:
value = value + 1
return value
def isVowel(phrase):
vowel = "a" "e" "i" "o" "u"
value = 0
for ch in phrase:
if ch in vowel:
value = value + 1
return value
def noVowel(ch):
vowel = "a" "e" "i" "o" "u"
value = 0
for i in ch:
if ch not in vowel:
value = value + 1
return value
def transform(word):
before = 'a'
answer = ""
for ch in word:
if Vowel(ch):
answer += ch
if noVowel(ch) and isVowel(before):
answer += ch
before = ch
return answer
def getMessage(original):
trans = ""
for word in original.split():
trans = trans + " " + transform(word)
trans = trans.strip()
return trans
if __name__ == '__main__':
print(getMessage("aeiou b"))

74,230,516 | <p>I am solving this Leetcode problem: <a href="https://leetcode.com/problems/find-pivot-index/" rel="nofollow noreferrer">https://leetcode.com/problems/find-pivot-index/</a>
And I came up with this solution:</p>
<pre><code>import java.util.ArrayList;
import java.util.List;
public class Solution {
public int pivotIndex(int[] nums) {
Integer result = null;
List<Integer> right = new ArrayList<>(nums.length);
List<Integer> left = new ArrayList<>(nums.length);
int leftSum, rightSum;
for (int i = 0; i < nums.length; i++) {
leftSum = 0;
rightSum = 0;
for (int j = 0; j < i; j++) {
left.add(nums[j]);
}
for (int num : left) {
leftSum += num;
}
for (int j = i + 1; j < nums.length; j++) {
if (j > nums.length) {
right.add(0);
} else {
right.add(nums[j]);
}
}
for (int num : right) {
rightSum += num;
}
if (leftSum == rightSum) {
result = i;
return result;
} else {
result = -1;
left.clear();
right.clear();
}
}
return result;
}
}
</code></pre>
<p>But I'm getting Time Limit Exceeded...
Can someone help me with some advise on how to make this run faster?<br />
Before, I was instantiating a new ArrayList object at the start of the first for loop, so I changed their scope so that only one instantiation happens and just cleared the ArrayLists at the end of the for loop.<br />
Same for leftSum and rightSum, I changed their scope for the whole method and just change their value to 0 at the start of the first for loop. I figured both these changed would make it faster but apparently didn't?<br />
My code is slow somewhere else I can't detect it right now.</p>
<p>Any tips / good practices would be highly appreciated as someone who's trying to prepare for the first job interviews in this field :)</p>

<p>I have a table of zipcodes. Each zipcode entry has 6 ints, that refer to words. I use joins from the words, to make zipcodes: "92121, San Diego, California, United States, CA, US"</p>
<p>If I know the exact zipcode, the query is quite fast:</p>
<p><a href="https://blackvelvetcollection.com/question.txt" rel="nofollow noreferrer">Full Question</a></p>
<p>I made this link to show the table and SELECT statement since StackOverflow appears to have some bugs when posting code.</p>
<p>However, if I do NOT know the zipcode and search by name, the query is really slow, as I must accommodate searching for all permutations of all words: "San Diego, CA", "San Diego, California", "San Diego, CA", "California San Diego", "92121 San Diego CA", etc</p>
<p>In order to accommodate all the permutations, I am doing a LIKE on every term, against every column. This is really slow (4 seconds) and I feel this statement can be made much more efficient.</p>
<p>The database contains all zipcode patterns, for all countries. Maybe I can search for "US", "CA", "UK", or "AU" beforehand, and limit the query to cities within the user"s home country?</p>
<p>Thoughts?</p>

74,230,552 | <p>When browser back button clicked the app redirects to the first url of the app. For example, current route is <code>localhost:3000</code> then I'm going to home <code>localhost:3000/home</code> and then to <code>localhost:3000/settings</code> and when I click on browser back button it redirects me to <code>localhost:3000</code> instead of <code>localhost:3000/home</code>.</p>
<p>I'm using angular 14, but when I started building the app angular was of version 13.
This is <code>app.module.ts</code>:</p>
<pre><code>@NgModule({
declarations: [AppComponent],
imports: [
...
BrowserModule,
AppRoutingModule,
],
providers: [
{ provide: RouteReuseStrategy, useClass: IonicRouteStrategy },
...
],
bootstrap: [AppComponent]
})
</code></pre>
<p>This is <code>app-routing.module.ts</code>:</p>
<pre><code>@NgModule({
imports: [
RouterModule.forRoot(routes, { preloadingStrategy: PreloadAllModules, onSameUrlNavigation: "reload" }),
BrowserAnimationsModule
],
exports: [RouterModule]
})
</code></pre>
<p>The routes all look like this:</p>
<pre><code>
{
path: "user/profile",
loadChildren: () => import("./user/profile/profile.module").then(m => m.ProfilePageModule),
canActivate: [LoggedGuard],
},
</code></pre>
<p>This is the navigation function that used everywhere for navigation:</p>
<pre><code>async go(path: string[], options: NavigationExtras = {}, showLoader: boolean = true) {
if(showLoader === true) {
await this.loader.start();
}
this.router.navigate(path, { replaceUrl: true, ...options});
}
</code></pre>

74,230,557 | <p>I am pretty new to html/css/sass and I'm currently developing a website for myself. When aligning items I notice that I sometimes want a padding of 1em to the right for one item, and then a padding of 2em to the top for another item etc. I do the definitions in a .scss file like this currently:</p>
<p>_master.scss:</p>
<pre><code>:root {
--pad-neg-left-1: 0 0 0 -1em;
--pad-top-2: 2em 0 0 0;
}
.pad-neg-left-1{
padding: var(--pad-neg-left-1);
}
.pad-top-2{
padding: var(--pad-top-2);
}
</code></pre>
<p>index.html:</p>
<pre><code><div class=".pad-top-2"> Hi </div>
</code></pre>
<p>This gets big and complex really fast if I want to add classes to my html objects to fit all purposes. Instead I would like a class that can take parameters and use it maybe like this:</p>
<p>_master.scss:</p>
<pre><code>function pad(top, right, bottom, left){
padding: top right bottom left;
}
</code></pre>
<p>index.html:</p>
<pre><code><div class=".pad(2, 0, 0, 0)"> Hi </div>
</code></pre>
<p>Is this possible?</p>
<p>I could write my div as this instead: <code><div style="padding: 2 0 0 0;"> Hi </div></code> but for some reason I heard from videos that it is bad to define styling straight in html and instead use classes. Is this wrong, or can I use some other approach?</p>

74,230,575 | <p>I am running my flask application with nohup command on my linux server. I am trying to save PID number as a variable or save just the PID number on output .</p>
<p>For an example , if i run my flask_application with nohup in below command</p>
<pre><code>nohup python /home/app/run_flask.py > /home/temp/run_flask.out 2> /home/temp/run_flask.err &
</code></pre>
<p>this will successfully run in the backgroup and i check if my pid running is by</p>
<pre><code> ps -ef | grep /home/app/run_flask.py
</code></pre>
<p>my server will return this</p>
<pre><code>farid 108708 1 0 23:50 pts/0 00:00:00 python /home/app/run_flask.py
farid 112265 83174 0 23:52 pts/0 00:00:00 grep --color=auto /home/app/run_flask.py
</code></pre>
<p>PID which i am trying to capture either as a variable or save it to file is 112265 so that i can include this in my shell script to kill process on certain condition . How can i achieve this ?</p>
<p>I have tried using this command and i was able to print out 112265 , however i am not sure i cant store this as variable by adding 'test1=ps ef....' and if this is the right approach . command used</p>
<pre><code>ps -ef | grep /home/app/run_flask.py | tr -s ' ' | cut -d ' ' -f2 | tail -1
</code></pre>

<p>The value is stored in the string status. How can i use it in a conditional to change the icon. There are three values for status. It can either be "Approved" , "Pending" or "Rejected"</p>
<p>I tried giving a conditional <code>if(status) == "Approved"</code> ? but it gives the error</p>
<pre><code>The element type 'bool' can't be assigned to the list type 'Widget'.

74,230,618 | <p>I am passing the method as follows But it is very complicated. I want to call methods directly without passing methods. Is there any way to do that?</p>
<pre><code>class Parent extends StatelessWidget {
const Parent({Key? key}) : super(key: key);
@override
Widget build(BuildContext context) {
return Child(onPressed: onPressed);
}
onPressed() {
print("onPressed");
}
}
class Child extends StatelessWidget {
const Child({
Key? key,
required this.onPressed,
}) : super(key: key);
final Function() onPressed;
@override
Widget build(BuildContext context) {
return Grandchild(onPressed: onPressed);
}
}
class Grandchild extends StatelessWidget {
const Grandchild({
Key? key,
required this.onPressed,
}) : super(key: key);
final Function() onPressed;
@override
Widget build(BuildContext context) {
return FloatingActionButton(
backgroundColor: Colors.black,
mini: true,
child: const Icon(
Icons.cached,
color: Colors.white,
),
tooltip: 'Change Camera',
onPressed: onPressed,
);
}
}
</code></pre>
<p>I'm envisioning something like Riverpod's StateNotifierProvider, etc. where you pass methods like you pass properties, but if you can make it easier, that's fine too.</p>
