59,700,383 | batch file code to detect 32-bit vs 64-bit office not working | <p>I'm trying to put together a batch file that would select the appropriate bit version of executables when run by the user. I found this code on stackoverflow:
<a href="https://stackoverflow.com/questions/35820375/batch-file-check-office-architecture-version">Batch file check office architecture version</a>
The problem is that it does not work when I paste it into a text file on my desktop and rename it .bat in my virtual machine that has 64-bit Office 2010 installed: it claims it is 32-bit, the default value set in the code. Not being adept in checking registry entries, I'm wondering if there isn't a ready-made version out there somewhere that actually works. I'm also wondering why there isn't a simple way to determine this. I would have thought that this is something that Microsoft would make easily accessible to developers. </p>

59,716,392 | Hot to tell Symfony http_client to read .htccess | I have a php application made in symfony, it needs this .htaccess to to work:
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
RewriteCond %{HTTP:Authorization} ^(.*)
RewriteRule .* - [e=HTTP_AUTHORIZATION:%1]
now I am writing some functional test and looks like the client can't find the controller for the route, this is the code:
$response = static::createClient()->request(
'POST',
'/api/login_check',
[
'body' => [
'username' => 'username',
'password' => 'secret123!#'
]
]
);
when I run the test I get this error:
2020-01-13T11:53:54+00:00 [error] Uncaught PHP Exception Symfony\Component\HttpKernel\Exception\NotFoundHttpException: "Unable to find the controller for path "/api/login_check". The route is wrongly configured." at /var/www/html/vendor/symfony/http-kernel/HttpKernel.php line 130
which is exactly the same error I use to have using postman before to add the .htaccess file.
Is there a way to make the http_client read the .htaccess file?
Or alternatively, how can I get rid of the .htaccess file?
thanks

59,719,904 | Vue Y U NO UPDATE |
Working my way learning about Vue. I chose it as the better alternative after looking at React, Angular and Svelte.
I have a simple example that its not working probably because I'm not getting/understanding the reactive behaviour of Vue.
Plain simple App:
> <template>
> <div id="app">
> <app-header></app-header>
> <router-view/>
> <app-footer></app-footer>
> </div>
> </template>
>
> <script>

> import Home from './components/Home.vue';
> import Footer from './components/Footer.vue';
> export default {
> components: {
> name: 'App',
> 'app-header': Header,
> 'app-footer': Footer
> }
> }
Where Home.vue and Footer.vue have plain HTML content on the template.
On Header.vue I have:
> <template>
> <div>
> <h1> The Header </h1>
> <nav>
> <ul>
> <li>Curr Player: {{ethaccount}}</li>
>
> <li>Prop owner: {{propOwner}}</li>

>

But I'm unable to get the header updated and unable to find what I'm doing wrong. Help.

59,749,080 | why I get this return value? | <p>Today I was practicing some return types, and put this code:</p>
<pre><code>def funcion(numero):
return numero
print(funcion)
</code></pre>
<p>And the output is</p>
<pre><code><function funcion at 0x7fc48554f950>
</code></pre>
<p>but the weirdest thing is that each time I try to run the code it appears other output with different digets/numbers at the end, except 0x7fc48554f950 will be 0x7f8658401950 for example.</p>
<p>I was wondering why this happens?
The output from python 2.7.x and 3.6.5 are different as well, which would be
and
awalys with the beginning and ea0.</p>

59,749,936 | how to sum up values of single dimentional array having same key in php | <p>For example: if strArr is ["B:-1", "A:1", "B:3", "A:5"] then your program should return the string A:6,B:2.</p>
<p>Your final output string should return the keys in alphabetical order. Exclude keys that have a value of 0 after being summed up.
Examples
Input: array("X:-1", "Y:1", "X:-4", "B:3", "X:5")

59,753,810 | Is there a way to handle generic function in go | <p>I am new to go, and wanted to implement a scheduler that will recieve tasks(i.e interval + handler).
I got stuck in the part where I should get the handlers as go is a static language(I can't get a generic function signature).
I came up with the following solution:
each "handler" func will get wrapped by empty-interface:</p>
<pre><code>type GenericFunc interface{}
add_task(GenericFunc(my_func), p1, p2,...)
</code></pre>
<p>which will result in the following struct as for saving the handler and its params:</p>
<pre><code>type Task struct {
handler reflect.Value
params []reflect.Value
...
}
</code></pre>
<p>Tasks execution would be invoked by:</p>
<pre><code>func (t *Task) execute() {
t.handler.Call(t.params)
}
</code></pre>
<p>My question is this the right way to treat generic functions or is there a more idiomatic solution I'm missing?
thx.</p>

59,759,612 | C# Syntax beyond me, a beginner | <p>Okay, so still very new to C#, so sorry if this is obvious...</p>
<p>There is some code I can't follow that was created by someone who is much better at C#than I am.</p>
<p>We have a class, call it "CC", and it has a number of fields, one of which is "FORM_NBR".</p>
<p>So, in a nutshell:</p>
<pre><code>public class CC
{
public CC();
//Many, many fields...
...
public long FORM_NBR { get; set; }
...
}
</code></pre>
<p>At some point, an object is created...</p>
<pre><code>CC c = new CC();
</code></pre>
<p>and then this line is called:</p>
<pre><code>c.FORM_NBR = c.FORM_NBR.GetCheckDigit(' ');
</code></pre>
<p>Now, there is this function deep in the library we inherited:</p>
<pre><code>public static short GetCheckDigit(this long nFormNbr, char chFormTypCd)
{
short nCkDgt = 0; // Default to 0
switch (chFormTypCd)
{
//Many, many cases...
...
default:
nCkDgt = CalculateCheckDigit(nFormNbr);
break;
}
return nCkDgt;
}
</code></pre>
<p>My question is this. Being new-ish to C#, how is GetCheckDigit getting called from a long? What is this syntax?</p>
<p>I don't even know how I would describe/google this!</p>

<p>Problem is when i intended to get the selected ones with <code>$_POST['check_list']</code>via foreach loop it prints <strong>"on"</strong> according to number of selected checkboxes. If user selects 3 checkboxes in <code>$_POST['check_list']</code> there are 3 elements which is <strong>"on"</strong> . When I select 2 things lets say , and print the <code>$_POST['check_list']</code> with <code>print_r</code> it outputs <code>Array ( [0] => on [1] => on [2] => on )</code>
I search a lot but couldn't manage to find solution. Appreciate any help thank you for interest.</p>
