Selenium can't find chromedriver.exe : <p>We're upgrading to .NET Core, and we have a crawling engine that uses Selenium for some tasks. We use <code>chromedriver.exe</code> and it works just fine in .NET 4.6.1. </p>
<p>For .NET Core, we created a console application, and added these packages:</p>
<pre><code> <ItemGroup>
<PackageReference Include="Selenium.WebDriver" Version="3.8.0" />
<PackageReference Include="Selenium.Support" Version="3.7.0" />
<PackageReference Include="Selenium.WebDriver.ChromeDriver" Version="2.34.0" />
</ItemGroup>
</code></pre>
<p>But when I run my code, I get this error:</p>
<blockquote>
<p>The chromedriver.exe file does not exist in the current directory or
in a directory on the PATH environment variable. The driver can be
downloaded at <a href="http://chromedriver.storage.googleapis.com/index.html" rel="noreferrer">http://chromedriver.storage.googleapis.com/index.html</a>.</p>
</blockquote>
<p>I can see that after build, <code>chromedriver.exe</code> is getting copied to <code>bin\Debug\netcoreapp2.0</code> folder. I also copied it manually to <code>bin\Debug</code> folder. But in both cases it can't be found. </p>
<p>What do I miss here?</p>

PLEASE help - HTML breaks in email : Good evening,
I am having such an issue. I am formatting an HTML email and it all seems to work on several browsers - but of course it seems like Outlook is not playing nice on Chrome and IE.
I have done a bit of research and know this is something I am missing - I have included the `border="0" style="display: block;">` on all of my images and included the table collapse command in the head:
[table
{
border-collapse: collapse;
}][1]
Yet, it is still not working in Outlook on the above browsers. Can someone please tell me what I am doing wrong. I've included screenshots and a link to the HTML. If someone could please please help - I would be so grateful!

Which React lifecycle method can I use `this` in before the render function is called : <p>i was previously catching an error in my code using the component will mount method which is now being depreciated this was my code prevoiusly:</p>
<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-js lang-js prettyprint-override"><code> componentWillMount() {
if (!this.context) {
throw new Error('Error');
}
}</code></pre>
</div>
</div>
</p>
<ul>
<li><p>I considered adding my code to the <code>constructor</code> but that would not work since i cant use <code>this.</code> in the constructor</p></li>
<li><p>I also considered considered other lifecycle methods such as <code>componentDidMount</code> but this is called after the render function</p></li>
</ul>
<p>what would be the best way to solve this issue? would it be bad practice to add my error catching code in the render function?</p>

How to write a query with NULL for missing values : <p>Below, I have 2 tables. I want to write a query that will return each <code>NAME</code> and the corresponding <code>UIN</code> value. If there is no <code>UIN</code> value, I want to return <code>NULL</code> for that entry instead</p>
<p><a href="https://i.stack.imgur.com/Do7pg.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Do7pg.png" alt="enter image description here"></a></p>
<p>For example, 2 entries should be like this for Samanta should be:</p>
<p><code>Bob 49638-001</code></p>
<p><code>Samantha NULL</code></p>
<p>I've tried <code>SELECT NAME JOIN EMPLOYEE_UIN.UIN INSERT "NULL" WHERE UIN = NULL</code> but no luck. I'm a beginner with SQL and I couldn't find a similar example on SO about this.</p>

How do I transfer file data into Vector? : I splited the file to String lines and put them in array indexes.
String fileString = readfromfile(fileEvents);
String[] fileLines = fileString.split("\n");
assuming this is the first index in fileLines:
14 57 9 2 www.buytickets.com
this is the constructor:
Orders (int EventID, int SoldtoCustomerID, int SoldtoEmployeesID, int NumberOfTickets, String URL)
the vector instance:
Vector<Orders> myOrders = new Vector<Orders>();
how do I transfer this line to first index in the vecotr so it would be like this:
(14,57,9,2,www.buytickets.com)
thank you :)

How would I create custom configurations - Java Minecraft Plugin : never really worked with custom .yml files before. I know, I know, dynamic is better and I'll agree. I have not coded in a very long time, and I'm getting back into it. If someone could provide assistance on my issue, that'd be great. Thanks! :)
So, I basically made a little system to create a custom .yml file every time a player joins with some default values. Here's what I'm using to create the custom configs: https://hastebin.com/wibikegawa.cpp
It does everything perfectly fine. But, when attempt to write to it, it creates a blank file. Code I'm using to write: https://hastebin.com/ovuxuzuzim.cpp
Thanks! :)
Some debugging to the console I did: https://hastebin.com/aveyegunen.vbs

SQL query for updating two columns of a row while checking whether they overlap with other rows of the same table : The table below shows 3 selected rows from the session table which contains 3 sessions for the same doctor on the same day but with different, starting and ending times.
I want to update the sessionStartTime and sessionEndTime columns of one row in this table while checking whether that sessionStartTime and sessionEndTime overlap other 2 rows. What I need is a correct SQL query for this.
For example, I want to edit the sessionStartTime as 2018-07-08 9:30:00 and sessionEndTime as 2018-07-08 10:30:00 of the row with id=1091 and as the starting time and ending time of this session doesn't overlap with other two row values the two values should be updated.But if I entered the two values sessionStartTime as 2018-07-08 8:20:00 and sessionEndTime as 2018-07-08 9:00:00 of the id=1091 it should not allow it to edit the row as there is already another session with id=1090 which contains the starting and ending time duration.
[enter image description here][1]

I would rather be thankful if a clear answer for this question is given sooner as I'm already stuck with the logic and query for a long period of time.

C# Listview - How to change the color of each new item : I have a listview that I add items to it whenever I click a button. I want each **new** item to be colored **red** and the **older** item **white**. So that means only one item can be colored red which is the newest item added to the listview.
I did something like this but this just alternates the colors red and white.
for (int i = 0; i <= listView1.Items.Count - 1; i++)
{
if (listView1.Items[i].Index % 2 == 0)
{
listView1.Items[i].BackColor = Color.Red;
}
else

How should a GRPC Service be hosted? : <p>I have created a GRPC Server in C# using the example given at <a href="http://www.grpc.io/docs/tutorials/basic/csharp.html" rel="noreferrer">Link</a>. Now I want to figure out as how should I be hosting this server so that I achieve following:</p>
<ul>
<li>Should I make this Server a Console application or a a Windows Service. If I make it a windows Service then updating the service will be cumbersome (which is a big negative) and if I make it a console app then updating will simply need shutting down exe. But that comes with the price of closing the same by mistake. Is there any other better way?</li>
<li>With IIS this issue won't b there as I can simply remove the site from LB and stop the website to perform the update but since GRPC won't be a part of IIS, I am not sure what's the way to get this working.</li>
</ul>
<p>Any references for the better architecture are welcomed.</p>

Why the Standard claims that containers are objects? : <p>Container's definition from the Standard:</p>
<blockquote>
<p>§23.2.1/1: <strong>Containers are objects</strong> that store other objects. They control allocation and deallocation of these objects through constructors, destructors, insert and erase operations.</p>
</blockquote>
<p>I think the container's definition above contradicts with the definition from C++ Primer book (which I prefer):</p>
<blockquote>
<p><strong>Container is a type</strong> whose objects hold a collection of objects of a given type. </p>
</blockquote>
<p>It's obvious that (abstract) type can't be an object (any object must occupy a region of storage).
You can say that C++ <strong>container is a class template</strong>. But templates are not objects too. There is a note about it from <a href="http://en.cppreference.com/w/cpp/language/object" rel="nofollow noreferrer">cppreference</a>:</p>
<blockquote>
<p>The following entities are not objects: value, reference, function, enumerator, <strong>type</strong>, non-static class member, bit-field, <strong>template</strong>, class or function template specialization, namespace, parameter pack, and this.</p>
</blockquote>
<p>So why the Standard claims that containers are objects? Maybe there is a mistake somewhere?</p>

Mocking non-interface types in Go : <p>Let me preface this by saying I'm pretty new to Go, so I am looking for mocking techniques when working with other libraries. I am well aware that interfaces and dependency injection are the best way to keep code testable and mockable.</p>
<p>While working with a 3rd party client library (Google Cloud Storage), I have run into a problem with attempting to mock the implementation of their client. The primary problem is that the types in the client library are not implemented with interfaces. I can generate interfaces to mimic the client implementation. However, the return values for some of the functions return pointers to underlying struct types which are tricky or impossible to mock due to private attributes. Here is a sample of the problem I am trying to solve:</p>
<pre><code>package third_party
type UnderlyingType struct {
secret string
}
type ThirdPartyClient struct {}
func (f *ThirdPartyClient) SomeFunction() *UnderlyingType {
return &UnderlyingType{
secret: "I can't mock this, it's a secret to the package"
}
}
</code></pre>
<p>Here is an annotated sample with the problem I'm trying to solve.</p>
<pre><code>package mock
// Create interface that matches third party client structure
type MyClientInterface interface {
SomeFunction() *third_party.UnderlyingType
}
type MockClient struct {
third_party.Client
}
// Forced to return the third party non-interface type 'UnderlyingType'
func (f *MockClient) SomeFunction() *UnderlyingType {
// No way to mock the value of the 'secret' property outside
// of the third-party package. Any underlying methods that
// depend on a non-nil reference to 'secret' will explode
// with the mock.
//
// TODO: Find a way to mock the 'secret' value
return &UnderlyingType{}
}
</code></pre>
<p>Is this even a mockable scenario? Are there special techniques to work around the fact that the library provides no interfaces as return types?</p>

Can I use library that used android support with Androidx projects. : <p>I know, <a href="https://stackoverflow.com/questions/50387207/error-while-merging-dex-program-type-already-present-android-support-v4-os-resu">androidx and support dependency causing multidex error</a>
We can not use androidx and android support at a same time. So I totally migrate to androidx. but one of my dependency lib used android support "lottie".</p>
<p>What can we do in above situation? Should I remove 'lottie' from my project.</p>

How to test type of thrown exception in Jest : <p>I'm working with some code where I need to test type of exception thrown by function (Is it TypeError, ReferenceError etc.).</p>
<p>My current testing framework is AVA and I can test it as a second argument <code>t.throws</code> method, like here:</p>
<pre class="lang-js prettyprint-override"><code>it('should throw Error with message \'UNKNOWN ERROR\' when no params were passed', (t) => {
const error = t.throws(() => {
throwError();
}, TypeError);
t.is(error.message, 'UNKNOWN ERROR');
});
</code></pre>
<p>I started rewriting my tests to Jest and couldn't find how to easily do that. Is it even possible?</p>

Visual Basic (Using Visual Studio 2017) : I am brand new to Visual Basic and am a little lost. I was trying to import what I thought was correct to be able to use classes that seem to pop up when using VBA macro functions. Right now my code is not recognizing Workbooks.
My main goal is to simply use a Visual Studio Windows Form in Visual Basic to open an excel file in a specific directory using a name that is typed in the text box, and save-as into a .txt file. It seems like I am missing a major import or COM reference. Any help?

filename1 = txtBoxExcelFileNameString.Text
End Sub
Private Sub btnExcelSaveAs_Click(sender As Object, e As EventArgs) Handles btnExcelSaveAs.Click
Workbooks.Open Filename:=path & filename1

<p>The <code>NODE_ENV=production webpack --output-file bundledFile.js</code> works great by itself. The part that is not working is the <code>&& cp package.json dist/</code>, I would like the script to copy my package.json (along with 2 other files actually, but just starting with this one) to the dist folder.

flask does not see change in .js file : <p>I made a change on one of the <code>.js</code> files that I use and no matter what I do, flask insists on picking up, from memory cache, the last version of the file, without the change.</p>
<p>To clarify, I have the following structure. It all starts with <code>foo.html</code></p>
<pre><code>return render_template foo.html
</code></pre>
<p><code>foo.html</code> has a form inside that calls flask with some data and then returns a second template <code>bar.html</code>:</p>
<pre><code>return render_template bar.html
</code></pre>
<p>This second template calls some <code>.js</code> file, placed in the <code>static</code> folder, but it doesn't update when the code changes.</p>
<p>I mention the structure above because if the <code>.js</code> file was placed on <code>foo.html</code> instead of <code>bar.html</code> then Flask <strong>would</strong> pick up the new changes on the file. But in <code>bar.html</code> Flask completely ignores them.</p>
<p>What is happening? </p>
<p>The only thing that worked was to click on "disable cache" on the browser and reload again.</p>

Java stack and heap memory management : <p>I want to know how the memory is being allocated in the following program:</p>
<pre><code>public class MemoryClass {
public static void main(final String[] args) {
int i = 0;
MemoryClass memoryClass = new MemoryClass();
memoryClass.myMethod(memoryClass);
}
private void myMethod(final Object obj) {
int i = 1;
String s = "HelloWorld!";
}
}
</code></pre>
<p>Now, as far as my understanding goes, the following diagram describes how the memory allocation takes place:<br>
<a href="https://i.stack.imgur.com/4Ttvc.png" rel="noreferrer"><img src="https://i.stack.imgur.com/4Ttvc.png" alt="Basic runtime memory allocation"></a></p>
<p><br>
In the above diagram, <strong>memory</strong>,<strong>obj</strong> and <strong>s</strong>, which are in the stack memory, are actually the references to their "<strong>actual objects</strong>" which are placed inside the heap memory.
<br>
Here is the set of questions that come to my mind:</p>
<ol>
<li>Where are the methods of <strong>s</strong> stored?</li>
<li>Had I created another object of <code>MemoryClass</code> inside <code>myMethod</code>, would JVM allocate memory for the same methods again inside the stack memory?</li>
<li>Would JVM free the memory allocated to <code>myMethod</code> as soon as it's execution is completed, if so, how would it manage the situation mentioned in question 2(<em>only applicable if JVM allocates memory multiple times to the same method</em>).</li>
<li>What would have been the case, if I had only declared <strong>s</strong> and did not initialize it, would JVM still allocate memory to all the methods of <code>java.lang.String</code> class,if so,why?</li>

How to access/expose kubernetes-dashboard service outside of a cluster? : <p>I have got the following services:</p>

curl: (60) server certificate verification failed. CAfile: /etc/ssl/certs/ca-certificates.crt CRLfile: none
More details here: http://curl.haxx.se/docs/sslcerts.html
curl performs SSL certificate verification by default, using a "bundle"
of Certificate Authority (CA) public keys (CA certs). If the default
bundle file isn't adequate, you can specify an alternate file
using the --cacert option.
If this HTTPS server uses a certificate signed by a CA represented in
the bundle, the certificate verification probably failed due to a
problem with the certificate (it might be expired, or the name might
not match the domain name in the URL).
If you'd like to turn off curl's verification of the certificate, use
the -k (or --insecure) option.
</code></pre>
<p>Trying the same without certificate validation. For curl it might be OK. but I have got the same in a browser, which is connecting though port forwarding via vagrant forwarded_port option.</p>
<pre><code>ubuntu@master:~$ curl -k https://localhost/ui
Unauthorized
</code></pre>
<p><strong>What I am doing wrong? and how to make sure I can access the UI?</strong> Currently it responds with Unauthorized.</p>
<p>The docs for the dashboard tell the password is in the configuration:</p>
<pre><code>ubuntu@master:~$ kubectl config view
apiVersion: v1
clusters: []
contexts: []
current-context: ""
kind: Config
preferences: {}
users: []
</code></pre>
<p>but it seems I have got nothing... <strong>Is it expected behavior? How can I authorize with the UI?</strong></p>

Data analysis in python : <p>I have to make two data analysis reports using descriptive statistics, making plenty of informative plots etc. </p>
<p>Problem is, I'm not sure what tools should I use? I started preparing one report in Jupyter Notebook using pandas, scipy.stats and matplotlib with intention to convert it somehow to pdf later on, so I can have report without code. After hour or two I realized it might not be the best idea. I even had problem with making good description of categorical data, since pandas <code>describe()</code> had limited functionality on this type of data.</p>
<p>Could you suggest me some tools that would be best in this case? I want to prepare aesthetic, informative report. It's my first time doing data analysis including preparing report.</p>

How to reasing and increase the value of string variable : Thank you for your attention, I have the next example in C++:
this->name=new char[strlen(nom)+1];
So, I want to know how can I implement this example in java?
the class have a :
private String name;
and I want to implement this method:
public void setNombre(String nom)
I try to do: this.name= new String(nom.length()+1);
In C++:
this->name=new char[strlen(nom)+1];
I try to do:
this.name= new String(nom.length()+1);

Can composer generate the `composer.lock` without actually download the packages? : <p>It does exist a command to generate the <code>composer.lock</code> from a <code>composer.json</code>?</p>
<p>Something similar ruby's <code>bundler</code> : <code>$ bundle lock</code></p>

Removing a sublist from a main list without knowing its position in the list : <p>So say i have a 2D list of randomly generated sub lists containing random numbers like this </p>
<pre><code>list = [(1,2),(2,3),(3,4),(4,5)]
</code></pre>
<p>How would I remove the sublist "(2,3)" from the main list if I didn't know its position in the list?
I tried using .pop but couldn't make it work without knowing the position of the sublist within the list.</p>

Regarding recurssive if else block : I am trying to understand how recursive works. Below is a code of If-else block.
public class Test {
public void test(int count){
if(count ==1){
System.out.println("Inside IF");
}
else{
System.out.println("Inside Else");
test(--count);
System.out.println("TEST");
}
}
public static void main(String[] args) {
Test t = new Test();
t.test(5);
}
}
The Output for the above code is
Inside Else
Inside Else
Inside Else
Inside Else
Inside IF
TEST
TEST
TEST
TEST
Could someone please help me understand why the TEST has been printed 4 times.
Thanks
