d7601 | train | AutoMapper uses Castle Dynamic Proxy which requires Reflection.Emit which is not supported on the phone.
If you want this you're going to need to look at building it all yourself. In terms of getting round the lack of reflection.Emit (if you really do need it) then you should look at using Mono.Cecil to provide this missing functionality.
A: Seems that automapper is working on silverlight edition so possible WP7/WP8 compatibility coming soon.
In the mean time there is a simple mapper library that you can use. It is very basic but probably meets most of your requirements for WP7 applications.
// Configure LazyMapper
Mapper.Create<SampleClass, SampleClassDto>();
// Perform mapping
var dto = Mapper.Map<SampleClass, SampleClassDto>(new SampleClass {
StringVal = "String1"});
Assert.AreEqual("String1",dto.StringVal);

d7602 | train | So, several ways to accomplish this.
My suggestion would be to utilize margin-top on the element you want to overflow. Everything else will render properly and only one item needs to be positioned properly.
Visual Representation:
HTML
<div id="one">Item 1</div>
<div id="two">Item 2</div>
<div id="three">Item 3</div>
CSS
#one, #two, #three {
position: relative;
margin: 0 auto;
}
#one {
width: 400px;
height: 200px;
background: #ABC;
}
#two {
width: 200px;
height: 100px;
background: #CBA;
margin-top: -50px;
}
#three {
width: 400px;
height: 300px;
background: #BBB;
}
Example provided here:
http://jsfiddle.net/dp83o0vt/
A: Instead of setting
top: -50px;
simply set
margin-top: -50px;
This way your .c still sticks to .b, and you don't have to mess with anything else.

d7603 | train | The error happens because } catch { is a relatively recent (ES2019) language feature called "optional catch binding"; prior to its introduction, binding the caught error (e.g. } catch (err) {) was required syntactically. Per node.green, you need at least Node 10 to have that language feature.
So why does this happen in ESLint? Per e.g. the release blog, version 7 has dropped support for Node 8; they're no longer testing against that version and more modern language features will be assumed to be supported.
To fix it, either:
*
*Upgrade Node (Node 8 is out of LTS, which is why ESLint dropped support); or
*npm install eslint@6 (with -g if you want to install globally) to use the older version of ESLint with Node 8 support.
A: In case it's helpful for anyone, I had a slightly different twist on the other answer. In my case, the error was happening during the Travis CI build process and causing it to fail. The solution in my case was to update my .travis.yml file to node_js: "16" | unknown | |
d7604 | train | HTTP 404 means the URL is not found:
https://en.wikipedia.org/wiki/HTTP_404
It usually tells me that my packaging or mapping or request URL is incorrect.
Start with the basics: write an index.html page and see that it's displayed.
It's not typical to have an index controller. Once you have that page working, see if you can map to something meaningful.
Is that controller in a package? I don't see a package statement at the top. It's impossible to be a Spring developer without being a solid Java developer first. No one would create a class without a package.
A: I modified your code a bit to make it work.

d7605 | train | You can set pyautogui.PAUSE to control the duration of the delay between actions. By default, it is set to 0.1 sec, that is why you are getting at most 10 clicks per second.
pyautogui.PAUSE = 0.01
for example will reduce the delay to allow 100 clicks per second if your hardware supports it.
From the doc, you can read the following:

d7606 | train | sometimes I receive these errors while terminating the process:
QProcess: Destroyed while process (" ... server.exe ...") is still
running
It seems you are not waiting for the process to gracefully terminate.
Here is a generic way to terminate a process you launched :
server->terminate();
server->waitForFinished(timeoutMS);
if (server->state() == QProcess::Running) {
server->kill();
}
Terminate will send a polite "can you please stop" signal, kill will abruptly stop the target process. How much time does it take for the server to shut down (it may be several seconds)? so you should have a generous timeout period which take this in account. | unknown | |

d7608 | train | The negative number as an integer is the two's complement. To flip the sign using two's complement you do like this:
"To get the two's complement of a binary number, the bits are
inverted, or "flipped", by using the bitwise NOT operation; the value
of 1 is then added to the resulting value, ignoring the overflow which
occurs when taking the two's complement of 0."
In JavaScript that would be:
n = ~n + 1;
If you are looking for performance, that is not likely to be the fastest way. That would most likely be to use the operator specifically designed for that:
n = -n;
A: It's not soo much faster. It does not make sense. When you need to negate the number noone can do it better than your CPU. http://jsperf.com/minus-vs-not
A: In case anyone is wondering how you would go back and forth between a negative & positive number (n) without using the + or - signs ...

d7611 | train | There is no easy optimal solution. One approximation is as follows:
*
*Pick the group with the largest size. Let its size be x
*Pick the largest group such that its size is less than 90-x
*Keep repeating step 2 until you cannot find such a group
*Remove the selected groups and repeat the process starting from Step 1
Eg. You would pick group1 (or group4 or groupN) first is step 1. In step 2 you would pick group4. Now the size is 80 and there are no groups smaller than 90-80=10. So stop and remove these two groups. In the next iteration, you will select groupN, followed by group2, and at last group3. In the last iteration you have only one group, that is group5. | unknown | |

}
also call the method on dom ready
<script type="text/javascript">
jQuery(function(){
RadionButtonSelectedValueSet('RBLExperienceApplicable', '1');
})
</script>
A: You can try this also
function SetRadiobuttonValue(selectedValue)
{
$(':radio[value="' + selectedValue + '"]').attr('checked', 'checked');
}
A: You can do more elegantly.
function RadionButtonSelectedValueSet(name, SelectedValue) {
$('input[name="' + name+ '"]').val([SelectedValue]);
}
A: Below script works fine in all browser:
function RadionButtonSelectedValueSet(name, SelectdValue) {
$('input[name="' + name + '"][value="' + SelectdValue + '"]').attr('checked',true);
}
A: $('input[name="RBLExperienceApplicable"]').prop('checked',true);
Thanks dude...
A: If the selection changes, make sure to clear the other checks first. al la...
$('input[name="' + value.id + '"]').attr('checked', false);
$('input[name="' + value.id + '"][value="' + thing[value.prop] + '"]').attr('checked', true);
A: for multiple dropdowns
$('[id^=RBLExperienceApplicable][value='+ SelectedVAlue +']').attr("checked","checked");
here RBLExperienceApplicable is the matching part of the radio button groups input tag ids.
and [id^=RBLExperienceApplicable] matches all the radio button whose id start with RBLExperienceApplicable
A: <input type="radio" name="RBLExperienceApplicable" class="radio" value="1" checked >
// For Example it is checked
<input type="radio" name="RBLExperienceApplicable" class="radio" value="0" >
<input type="radio" name="RBLExperienceApplicable2" class="radio" value="1" >
<input type="radio" name="RBLExperienceApplicable2" class="radio" value="0" >
$( "input[type='radio']" ).change(function() //on change radio buttons

A: <asp:RadioButtonList ID="rblRequestType">
<asp:ListItem Selected="True" Value="value1">Value1</asp:ListItem>
<asp:ListItem Value="Value2">Value2</asp:ListItem>

You can set checked like this.
var radio0 = $("#rblRequestType_0");
var radio1 = $("#rblRequestType_1");
radio0.checked = true;
radio1.checked = true;
A: A clean approach I find is by giving an ID for each radio button and then setting it by using the following statement:
document.getElementById('publicedit').checked = true;
A: Can be done using the id of the element
example
<label><input type="radio" name="travel_mode" value="Flight" id="Flight"> Flight </label>
<label><input type="radio" name="travel_mode" value="Train" id="Train"> Train </label>
<label><input type="radio" name="travel_mode" value="Bus" id="Bus"> Bus </label>
<label><input type="radio" name="travel_mode" value="Road" id="Road"> Other </label>
js:
$('#' + selected).prop('checked',true);
A: This is the only syntax that worked for me
$('input[name="assReq"][value="' + obj["AssociationReq"] + '"]').prop('checked', 'checked');
A: document.getElementById("TestToggleRadioButtonList").rows[0].cells[0].childNodes[0].checked = true;
where TestToggleRadioButtonList is the id of the RadioButtonList. | unknown | |

def <<(tag)
tag.published = true
proxy_association.owner.posts_tags+= [tag]

d7616 | train | This is pretty simple really.
You don't need the template but you do need to be in the correct namespace.
namespace std {
void swap(VecFoo& lhs, VecFoo& rhs) {
std::cout << "void swap(VecFoo&, VecFoo&)\n";
//do your custom swap here!!!
}
}
A: std::move requires the class to be move-assignable and move-constructible, but the class VecFoo is not any of them.
You added a bunch of method to support these constraints in the class Foo, which didn't requires any (you are swapping pointers).
Also, there is a typo in the swap declaration: it says std::swap<VecFo> instead of std::swap<VecFoo>.
Finally, I would recommend NOT using friend. Just add a method swap to the class and put the logic there. | unknown | |
d7617 | train | One can register a custom from-python converter with Boost.Python that handles conversions from NumPy array scalars, such as numpy.uint8, to C++ scalars, such as unsigned char. A custom from-python converter registration has three parts:
*
*A function that checks if a PyObject is convertible. A return of NULL indicates that the PyObject cannot use the registered converter.
*A construct function that constructs the C++ type from a PyObject. This function will only be called if converter(PyObject) does not return NULL.
*The C++ type that will be constructed.
Extracting the value from the NumPy array scalar requires a few NumPy C API calls:
*
*import_array() must be called within the initialization of an extension module that is going to use the NumPy C API. Depending on how the extension(s) are using the NumPy C API, other requirements for importing may need to occur.
*PyArray_CheckScalar() checks if a PyObject is a NumPy array scalar.
*PyArray_DescrFromScalar() gets the data-type-descriptor object for an array scalar. The data-type-descriptor object contains information about how to interpret the underlying bytes. For example, its type_num data member contains an enum value that corresponds to a C-type.
*PyArray_ScalarAsCtype() can be used to extract the C-type value from a NumPy array scalar.
Here is a complete example demonstrating using a helper class, enable_numpy_scalar_converter, to register specific NumPy array scalars to their corresponding C++ types.

A few things to note from the interactive usage:
*
*Boost.Python was able to extract boost::uint8_t from both numpy.uint8 and int Python objects.
*The enable_numpy_scalar_converter does not support promotions. For instance, it should be safe for test_specific_int32() to accept a numpy.int8 object that is promoted to a larger scalar type, such as int. If one wishes to perform promotions:
*
*convertible() will need to check for compatible NPY_TYPES
*construct() should use PyArray_CastScalarToCtype() to cast the extracted array scalar value to the desired C++ type.
A: Here's a slightly more generic version of the accepted answer:
https://github.com/stuarteberg/printnum
(The converter is copied from the VIGRA C++/Python bindings.)
The accepted answer points out that it does not support casting between scalar types. This converter will allow implicit conversion between any two scalar types (even, say, int32 to int8, or float32 to uint8). I think that's generally nicer, but there is a slight convenience/safety trade-off made here.

{
$country = $this->directoryBlock->getCountryHtmlSelect();
return $country;
}
use \Magento\Customer\Model\ResourceModel\Group\Collection and the above code in your block.
<div class="field group_id required">
<label for="group_id" class="label"><span><?php echo __('Group') ?></span></label>
<div class="control">
<select name="group_id">
<?php foreach ($groups as $key => $data) {
?>
<option value="<?php
echo $data['value']; ?>"><?php echo $data['label']; ?></option>
<?php }?>
</select>
</div>

And in the phtml file add the above field.
I know it's an old post, but giving the solution just in case anyone needs it.
A: Create your own module instate of using /app/code/local/Mage/Customer/controllers/AccountController.php. Please add the following code in your congig.xml if your module name Custom and namespace Mymodule.
<global>
<fieldsets>
<customer_account>
<group_id><create>1</create><update>1</update></group_id>
</customer_account>
</fieldsets>
</global>
<frontend>
<routers>
<customer>
<args>
<modules>
<Mymodule_Custom before="Mage_Customer_AccountController">Mymodule_Custom</Mymodule_Custom>
</modules>
</args>
</customer>
</routers>
This will override your AccountController. Now find the following code for the controller.
<?php
require_once(Mage::getModuleDir('controllers','Mage_Customer').DS.'AccountController.php');
class Mymodule_Custom_AccountController extends Mage_Customer_AccountController
{
public function createPostAction()
{
$session = $this->_getSession();
if ($session->isLoggedIn()) {
$this->_redirect('*/*/');
return;
}
$session->setEscapeMessages(true); // prevent XSS injection in user input
if (!$this->getRequest()->isPost()) {
$errUrl = $this->_getUrl('*/*/create', array('_secure' => true));
$this->_redirectError($errUrl);
return;
}
$customer = $this->_getCustomer();
try {
$errors = $this->_getCustomerErrors($customer);
if (empty($errors)) {
if($this->getRequest()->getPost('group_id')){
$customer->setGroupId($this->getRequest()->getPost('group_id'));
} else {
$customer->getGroupId();
}
$customer->cleanPasswordsValidationData();
$customer->save();
$this->_dispatchRegisterSuccess($customer);
$this->_successProcessRegistration($customer);
return;
} else {
$this->_addSessionError($errors);
}
} catch (Mage_Core_Exception $e) {
$session->setCustomerFormData($this->getRequest()->getPost());
if ($e->getCode() === Mage_Customer_Model_Customer::EXCEPTION_EMAIL_EXISTS) {
$url = $this->_getUrl('customer/account/forgotpassword');
$message = $this->__('There is already an account with this email address. If you are sure that it is your email address, <a href="%s">click here</a> to get your password and access your account.', $url);
$session->setEscapeMessages(false);
} else {
$message = $e->getMessage();
}
$session->addError($message);
} catch (Exception $e) {
$session->setCustomerFormData($this->getRequest()->getPost())
->addException($e, $this->__('Cannot save the customer.'));
}
$errUrl = $this->_getUrl('*/*/create', array('_secure' => true));
$this->_redirectError($errUrl);

Starting with Spring Session 2.0, DefaultCookieSerializer uses Base64 encoding by default. So what you're actually seeing as session cookie value is the Base64 encoded session id.

d7626 | train | This approach seems somewhat common:
*
*Maintain a completely separate identity database. There should be no connection at all with any of the Line-Of-Business (LOB) databases.
*Each LOB database should have its own user table, with appropriate referential integrity constraints with other LOB tables, e.g. events or messages in your case.
*When a user hits one of your LOB web sites for the first time, he should be "enrolled" in the LOB database. A LOB user record is inserted. Use the access token to call the identity server to get any demographic information your LOB site will need.
*When a user hits one of your LOB web sites for the Nth time, you can use the access token to call the identity server and get the most recent, up-to-date demographic information, just in case any of it has changed since his last visit. You can then store this information in the LOB user table so that it is available to you offline, e.g. if you need to push marketing emails you'll have a copy of the email address.
The advantage of this approach is separation of concerns and the ability to support more than one authentication provider (e.g. in the future you could support Facebook or Google+ logins as well).
Also you avoid any dependencies between the identity server and the LOB servers, so you can add or remove lines of business as needed, and you keep the identity server nice and lightweight. | unknown | |

# response = client.put(url, data=None, files=files)
# You can test it using the `requests` instead of Client()

class AudioSerializer(serializers.Serializer):
""" AudioSerializer """
audio = serializers.FileField(...)

A: Inspired by @athansp's answer, I compared the source code of client.post and client.put and it turns out, put's implementation slightly differs from post, so a workable way of submitting files with put is:

client = Client()
with open('my_modified_audio.mp3', 'rb') as fp:
response = client.put(

Create table emp_avg as
Select e.employee_id, e.department_id from HR.employees e where 1=0;
A: That's not valid syntax. The point of an anchored type declaration (the %type syntax) in PL/SQL is that when the underlying data type changes, the PL/SQL code uses the new type automatically. But that doesn't work when you're defining a table where Oracle has to know the actual data type when it writes a data block to disk and can't just dynamically recompile the table when the parent data type changes. When you create a table, you have to specify actual data types. | unknown | |

d7633 | train | This is a bit hard to answer without seeing the whole compilation. However I often got this error when compiling third-party schemas in the case when the same schema was included via different URLs.
I.e. I've implemented a project which compiled an extensive set of OGC Schemas. The problem was that these schemas referenced each other via relative and absolute URLs. So when I customized one of the schemas there were other schemas for the same namespace URI. Since JAXB processes imports and includes, it is not quite transparent what exactly gets compiled. Try to check your XJC logs for cues or - if you compile schemas directly via URLs (which is not recommended) - go through a logging proxy and see what actually gets accessed. | unknown | |

I think, you have to add a filename behind the \Desktop. Desktop is an existing directory and cannot be opened as file ...
And - btw - it might be necessary to add -S Servername...
UPDATE
Found this here
Whenever I get this message, it's because of one of three things:
1) The path/filename is incorrect (check your typing / spelling)
2) The file does not exist. (make sure the file is where you expect it
to be)
3) The file is already open by some other app. (close the other app to
release the file)
For 1) and 2) - remember that paths are relative to where bcp is
executing. Make sure that bcp.exe can access the file/path from it's
context.

A: I figured it out. It was not as complicated as I first thought. Just needed a function to calculate the sum. Perhaps it could be more efficient, I would love any ideas on that, but here it is:
$rowColumns = array();
for($i=0;$i<=$count-1;$i++)
{
$currentRow = $rows[$i];
$currentCol = $cols[$i];
//count occurences of columns in row
$colSum = $this->getColumnOccurences($count,$rows,$cols,$currentRow,$currentCol);
$rowColumns[$currentRow][$currentCol] = $colSum;
}
private function getColumnOccurences($count,$rows,$cols,$rowValue,$colValue)

{
if($rows[$i] == $rowValue && $cols[$i] == $colValue)

In this case, the real question is how to make the field nillable on the Delphi side.
From this post of J.M. Babet:
Support for 'nil' has been an ongoing issue. Several built-in types of
Delphi are not nullable. So we opted to use a class for these cases
(not elegant but it works). So with the latest update for Delphi 2007
I have added several TXSxxxx types to help with this. Basically:
TXSBoolean, TXSInteger, TXSLong, etc. TXSString was already there but
it was not registered. Now it is. When importing a WSDL you must
enable the Use 'TXSString for simple nillable types' option to make
the importer switch to TXSxxxx types. On the command line it is the
"-0z+" option.
The DocWiki for the Import WSDL Wizard also shows two options related to nillable elements:
*
*Process nillable and optional elements - Check this option to make the WSDL importer generate relevant information about optional
and nillable properties. This information is used by the SOAP runtime
to allow certain properties be nil.
*Use TXSString for simple nillable types - The WSDL standard allows simple types to be nil, in Delphi or NULL, in C++, while Delphi
and C++ do not allow that. Check this option to make the WSDL importer
overcome this limitation by using instances of wrapper classes. | unknown | |

d7653 | train | You should better use $_SERVER['REQUEST_URI']. Since it is the last string in your URL, you can use the following function:
function getIdFromUrl($url) {
return str_replace('/', '', array_pop(explode('-', $url)));
}
@Kristian 's solution will only return numbers from 0-9, but this function will return the id with any length given, as long as your ID is separated with a - sign and the last element.
So, when you call
echo getIdFromUrl($_SERVER['REQUEST_URI']);
it will echo, in your case, 1.
A: If the ID will not always be the same number of digits (if you have any ID's greater than 9) then you'll need something robust like preg_match() or using string functions to trim off everything prior to the last "-" character. I would probably do:
<?php
$parts = parse_url($_SERVER['REQUEST_URI']);
if (preg_match("/truck-gallery-(\d+)/", $parts['path'], $match)) {
$id = $match[1];
} else {
// no ID found! Error handling or recovery here.
}
?>
A: Use the $_SERVER['REQUEST_URI'] variable to get the path (Note that this is not the same as the host variable, which returns something like http://www.yoursite.com).
Then break that up into a string and return the final character.
$path = $_SERVER['REQUEST_URI'];
$ID = $path[strlen($path)-1];
Of course you can do other types of string manipulation to get the final character of a string. But this works. | unknown | |

On Sheet 2 list all the possible categories in column A then in column B1 put
= sumif(Sheet1!C:C,A1,Sheet1!D:D)
then copy down. This will Get you the totals by category.
If you want to use VBA, you will still need a list of categories setup somewhere, either hard coded or listed somewhere that you can loop through.
If your list was in column A on Sheet2 then you would:
dim ws as worksheet
set ws = Worksheets("Sheet2")
For each i in ws.range(ws.Range("A1"),ws.Range("A1").offset(xldown)).Cells
i.offset(,1) = WorksheetFunction.Sumif(Worksheets("Sheets1").Range("C:C"), _

d7658 | train | Instead of making Vue do the same work over and over, You could make use of the v-else directive, which may work better for you:
<li v-if="!$auth.check()" class="pull-right" v-cloak>
<router-link :to="{ name: 'register' }">Register</router-link>
</li>
<li v-else class="pull-right">
<a href="#" @click.prevent="$auth.logout()">Logout</a>
</li>
A: v-cloak is not helping because that gets taken away as soon as the Vue app is ready. Apparently there's a delay from when Vue is ready and when the $auth function returns a response. I'd recommend hiding all of the login/logout links until $auth returns something.
You'd have to hook into what $auth returns somehow, and use that hook to change the authCheckDone to true.
Vue {
data: {
authCheckDone: false
...
}
}
<ul class="list-inline">
<li>
<router-link :to="{ name: 'home' }">Home</router-link>
</li>
<span v-if="authCheckDone">
<li v-if="!$auth.check()" class="pull-right">
<router-link :to="{ name: 'login' }">Login</router-link>
</li>
<li v-if="!$auth.check()" class="pull-right" v-cloak>
<router-link :to="{ name: 'register' }">Register</router-link>
</li>
<li v-if="$auth.check()" class="pull-right">
<a href="#" @click.prevent="$auth.logout()">Logout</a>
</li>
</span>
</ul>
A: You have to wait a bit until vue-auth is actually ready. From the docs:
ready
*
*Get binded ready property to know when user is fully loaded and checked.
*Can also set a single callback which will fire once (on refresh or entry).
<div v-if="$auth.ready()">
<vue-router></vue-router>
</div>
<div v-if="!$auth.ready()">
Site loading...
</div>
created() {
this.$auth.ready(function () {
console.log(this); // Will be proper context.
});
}
In other words, instead of v-cloak use:
<div class="panel panel-default" v-if="$auth.ready()">
Note: this can do some quick "flashing" of a white page. In that case you may want to add a loading image or something, like:
<div v-if="!$auth.ready()">
<img src="loading.gif">
</div>
Naturally, if this div is close to the other v-else can be used. | unknown | |

jQuery("#firmos").html($(this).val());
In your document ready function it would look like this.
jQuery(function() {
jQuery('#list4').jqDropDown({
optionChanged: function(){
jQuery("#firmos").html($(this).val());
},
direction: 'up',
defaultStyle: false,
containerName: 'theContainer',
toggleBtnName: 'awesomeToggleClass',
optionListName: 'thisListIsRocking',
effect: 'fade',
effectSpeed: 300
});
});
Edited
Actually if you want to redisplay the option in another element this control has a parameter called place holder
you could do this.
jQuery(function() {
jQuery('#list4').jqDropDown({
placeholder: '#firmos',
direction: 'up',
defaultStyle: false,
containerName: 'theContainer',
toggleBtnName: 'awesomeToggleClass',
optionListName: 'thisListIsRocking',
effect: 'fade',
effectSpeed: 300
});
});
Edited Again
If you want a custom value you can do something like this
jQuery(function() {
jQuery('#list4').jqDropDown({
optionChanged: function(){
jQuery("#firmos").html((function (currentElement) {
switch (currentElement.val())
{
case "someval":
return "somethingSpecial1";
break;
case "someval2":
return "somethingSpecial2";
break;
/// more case statements.
}
})($(this)));
},
direction: 'up',
defaultStyle: false,
containerName: 'theContainer',
toggleBtnName: 'awesomeToggleClass',
optionListName: 'thisListIsRocking',
effect: 'fade',
effectSpeed: 300
});
});
A: Well, I looked that this plugin just replicates a select element in a list <li> and seems not possible to get the exact changed value from the select because it doesn't change if you see the DOM (that makes me assume that the onchange event from that plugin is used just to trigger something when your list changes).
So, it seems you need to do some tricky thing to get the selected value implementing an onchange event recreation.
Like this:
Live Demo: http://jsfiddle.net/oscarj24/nuRKE/
$(function () {
var firmos = $('#firmos');
$('#list4').jqDropDown({
direction: 'up',
defaultStyle: false,
containerName: 'theContainer',
toggleBtnName: 'awesomeToggleClass',
optionListName: 'thisListIsRocking',
effect: 'fade',
effectSpeed: 300
});
//This will be your new 'onchange' event when using 'jqDropDown' plugin.
$('ul .ddOption').on('click', function(e){
var selected = $.trim($(e.target).text());
switch (selected)
{
case 'Aspen':
firmos.html('You selected Aspen.');
break;
case 'Tokyo':
firmos.html('You selected Tokyo.');
break;
//Do the same for other options.
}
});

jLabel1.setIcon(new javax.swing.ImageIcon("C:\\Users\\admin\\Desktop\\Picture 34029.jpg"));
Here i posted the code that got generated automatically in netbeans.Hope my code helps in this regards keep coding goodluck.
A: You have to supply to the JLabel an Icon implementation (i.e ImageIcon). You can do it trough the setIcon method, as in your question, or through the JLabel constructor:
Image image=GenerateImage.toImage(true); //this generates an image file
ImageIcon icon = new ImageIcon(image);
JLabel thumb = new JLabel();
thumb.setIcon(icon);
I recommend you to read the Javadoc for JLabel, Icon, and ImageIcon. Also, you can check the How to Use Labels Tutorial, for more information.

q.split(",").forEach(function(value){
$('input[data-value='+ value +']').prop('checked', true);
})
A: You can use a simple .each() loop to achieve this with jQuery, or Array.prototype.foreach() in vanilla JavaScript.
If you actually have a string of numbers to start off with, you'll need to split them out into an array by running .split() on the comma.
This can be seen in the following example:
// If you have a string rather than an array
const q = "5,1,3,4";
const values = q.split(",");
// If you start with an array
//const values = [5, 1, 3, 4];
$(values).each(function(index, value) {
$('input[data-value=' + value + ']').prop('checked', true);

d7671 | train | Combine offers extensions around URLSession to handle network requests unless you really need to integrate with OperationQueue based networking, then Future is a fine candidate. You can run multiple Futures and collect them at some point, but I'd really suggest looking at URLSession extensions for Combine.
struct User: Codable {
var username: String
}
let requestURL = URL(string: "https://example.com/")!
let publisher = URLSession.shared.dataTaskPublisher(for: requestURL)
.map { $0.data }
.decode(type: User.self, decoder: JSONDecoder())
Regarding running a batch of requests, it's possible to use Publishers.MergeMany, i.e:
struct User: Codable {
var username: String
}
let userIds = [1, 2, 3]
let subscriber = Just(userIds)
.setFailureType(to: Error.self)
.flatMap { (values) -> Publishers.MergeMany<AnyPublisher<User, Error>> in
let tasks = values.map { (userId) -> AnyPublisher<User, Error> in
let requestURL = URL(string: "https://jsonplaceholder.typicode.com/users/\(userId)")!
return URLSession.shared.dataTaskPublisher(for: requestURL)
.map { $0.data }
.decode(type: User.self, decoder: JSONDecoder())
.eraseToAnyPublisher()
}
return Publishers.MergeMany(tasks)
}.collect().sink(receiveCompletion: { (completion) in
if case .failure(let error) = completion {
print("Got error: \(error.localizedDescription)")
}
}) { (allUsers) in
print("Got users:")
allUsers.map { print("\($0)") }
}
In the example above I use collect to collect all results, which postpones emitting the value to the Sink until all of the network requests successfully finished, however you can get rid of the collect and receive each User in the example above one by one as network requests complete. | unknown | |
d7672 | train | This expression will get you 50% of the way there:
(?<=:\s*)(".*?"(?<!\\")|\-?(0|[1-9]\d*)(\.\d+)?([eE][+-]?\d+)?)(?=\s*})
Or, when written as a multi-line regex:
(?x:
(?<=:\s*) # After : + space
(
".*?"(?<!\\") # String in double quotes
| # -or-
\-? # Optional leading -ve
(0|[1-9]\d*) # Number
(\.\d+)? # Optional fraction
([eE][+-]?\d+)? # Optional exponent
)
(?=\s*}) # space + }
)
This will not match your nested object example ({ "not": { "want" ...) or rather, it will match, but on the wrong thing. Also, your final example ({ "nothing": 0 } => null / not found) is difficult because 0 is a valid number. To work around the this problem, I would just check the result in procedural code and replace a result of 0 with null.
The nested objects problem is a whole different ball game though. It's getting into the realm of lexical analysis rather than simple tokenizing. At that point, you might as well just use a JSON library because you'd be writing a full JSON parser anyway. Fortunately, JSON is a simple enough grammar that it wouldn't be that expensive to use a third party library - certainly no more than doing it yourself.
I think the short answer is: from a simple { "name" : <value> } object, yes, but from anything more complicated, no.
For info on the JSON syntax, see http://www.json.org/. | unknown | |
d7673 | train | start_tls() and ldaps is mutually exclusive, meaning you cannot issue start_tls() on the ssl port (standard 636), or initiate ldaps on an unecrypted port (standard 389). The start_tls() command initiate a secure connection on the unencrypted port after connection is initiated, so you would then issue this before the bind takes place to make it encrypted. Another set of common ports is 3268 (unecrypted) and 3269 (ssl) which might be enabled in your server.
ldap_set_option(NULL, LDAP_OPT_DEBUG_LEVEL, 7);
is logging to your web servers error log, depending on your log level, or to stout (from PHP CLI). To gain more information here, check your web server log level setting, or simply run your php script from command line.
To successfully use the ssl port, you need to specify the ldaps:// prefix, while on the unencrypted port this is not necessary (with a ldap:// prefix).
Looking at your code, this could be a protocol version issue as PHP by default use version 2. To solve this, you can issue:
ldap_set_option($conn, LDAP_OPT_PROTOCOL_VERSION,3);
ldap_set_option($conn, LDAP_OPT_REFERRALS,0);
before you attempt to bind.
You can also have a look at the code in Problems with secure bind to Active Directory using PHP which I successfully use in CentOS 5, but is having problems in Ubuntu. If your server has an open unencrypted port, it's a good idea to do an unencrypted test bind against it to rule out any connectivity issues.
To check if the port is open, you can check if telnet connects to it, E.G:
telnet my.server.com 3268
If the port is open, then you should be able to bind using it.
*Edit: If the ssl certificate is deemed invalid, the connection will fail, if this is the case, setting the debug level to 7 would announce this. To get around this specific problem you need to ignore the validity:
You can ignore the validity in windows by issuing
putenv('LDAPTLS_REQCERT=never');
in your php code. In *nix you need to edit your /etc/ldap.conf to contain
TLS_REQCERT never
A: The port 636 is the SSL enabled port and requires an SSL enabled connection.
You should try to connect on port 389, or change your code to include the secure layer (much more complex).
Kind regards,
Ludovic
A: To connect using SSL you should try
$ldapconn = ldap_connect('ldaps://'.$ldaphost);
This will automatically connect on port 636 which is the default ldaps-port. Depending on your server installation and configuration it may be possible that connections are only allowed on port 389 (using no encryption or using TLS) or only on port 636 using SSL-encryption. Although it might be possible that your server exposes other ports. So in general you need to know which port you're gonna connect to and which encryption method the server requires (no encryption, SSL or TLS).
A: Is the certificate of the LDAP server signed by a valid CA? Maybe your client just rejects the certificate! | unknown | |
d7674 | train | Using CDI in JAVA SE requires the beans.xml to be put in META-INF
although this is optional since Java EE 7.
Then, set discovery mode to annotated and your producer should be detected.

Now it's time to depend on implementations.
First, Deltaspike itself :
<dependency>
<groupId>org.apache.deltaspike.core</groupId>

d7675 | train | The easiest way is Pandas. Read data from file into DataFrame:
import pandas as pd
df = pd.read_csv('file.txt', sep=' ')
1) Show students names with 22 age.
result = df[df['Age'] == 22]
2) Show students of Electronics.
result = df[df['Faculty'] == 'Electronics']
A: I can give you a hint on building a dictionary:
a = []

keys = f.readline().strip().split(' ', 4)
for line in f:
val = line.strip().split(' ', 4) # spacebar in file
a.append(dict(zip(keys, val)))

d7676 | train | Raw sockets, as given by the example above (by Carl) can work to give you access for L3 header. However, note that on more up-to-date Windows (XP SP3, Vista and 7) raw sockets are greatly restricted by the socket layer, making it difficult to send arbitrary data of your choosing.
You can also use special libraries that allow for a much more raw access to the Ethernet adapter. WinPcap (for Windows) or libpcap (for Linux) will allow you to manipulate the entire packet data, including the Ethernet header, and indeed send any other L2 protocol you wish. | unknown | |

d7679 | train | The problem is that when you are selecting a folder and updating self.label_directory with the String of the path to the selected folder it is manipulating the grid and expanding your Click Here Button.
To fix this issue, firstly button_1 should have a its sticky option set to W, so then it doesn't move to the right side of it's grid cell, when it's grid cells width is manipulated.
Another issue you have is that you are increasing you rows and columns of your grid placement too much, you should only increment by the needed spaces, for example, you should start at row 1 and then place your next row at row 2, this helps make sure it is easy to understand where each element is placed.
With that all said I believe this code will fix the issue suitably:
import tkinter as tk
from tkinter import *
import tkinter.filedialog as fdialog
class karl(Frame):
def __init__(self):
tk.Frame.__init__(self)
self.pack(fill = tk.BOTH)
self.master.title("Image Selector")
self.master.geometry("500x500")
self.master.resizable(0, 0)
self.pack_propagate(0)
self.label_button_1 = Label(self, text="Select directory for picking images")
self.label_button_1.grid(row = 0, column = 0, columnspan = 1, sticky = W)
self.button_1 = tk.Button(self, text="CLICK HERE", width=25, command=self.open_dialog_box_to_select_folder)
self.button_1.grid(row=0, column=1, columnspan=2, sticky=W)
self.label_for_label_directory = Label(self, text="Current chosen directory")
self.label_for_label_directory.grid(row=1, column=0, rowspan=1, columnspan=1, sticky=W)
self.label_directory = Label(self, text="")
self.label_directory.grid(row=1, column=1, rowspan=1, columnspan=2, sticky=W)
self.label_for_entry_for_class_label_values = Label(self, text="Enter (+) seperated class labels\nto be assigned to the images")
self.label_for_entry_for_class_label_values.grid(row = 2, column = 0, rowspan = 1, columnspan = 2, sticky = W)
self.entry_for_class_label_values = Entry(self)
self.entry_for_class_label_values.grid(row = 2, column = 1, rowspan = 1, columnspan = 1, sticky = W)

self.chosen_directory_name = fdialog.askdirectory()
self.label_directory.config(text = self.chosen_directory_name)

I changed the elements previously mentioned to accomplish this, if you have any questions about my solution feel free to ask :)
Here is your tkinter program converted to an excel file, to visualize how the grid system works, the light blue is where your path string will be put when you select a folder.
When you select a long file path, the path_label expands (the light blue section of the excel, this will push the click me button to the right. So far right that it will push the button of the windows view-able area like so. | unknown | |
d7680 | train | Check the value being assigned to finalrow.
Without having your file available, this is difficult to diagnose. I'm unable to find any obvious errors in your code, so I'll go based on experience.
There are quite a few ways to determine what the final row of a spreadsheet is. You're using my favorite, but it has a couple pitfalls:
*
*Column A could be blank. I usually encounter this when using data pasted from another sheet or an SQL query, but this would be project specific.
*Column A could extend beyond 12000 rows. I usually encounter this when I've populated column A with a formula and "autofilled" too far down. "End(xlUp)" would then go to "A1".
To (usually) get around either of these issues, I always use the max possible row as a starting point; A65563 for Office 2010 or earlier, or A1048576 for anything after that. It doesn't take any longer to process, and gets more consistent results. | unknown | |
d7681 | train | If NGINX work through PHP-FPM (FastCGI Process Manager) then you can uncomment the important part for PHP is the location ~ \.php$ {} stanza in the default vhost which is defined in the file
vi /etc/nginx/sites-available/default
like
[...]
location ~ \.php$ {
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fastcgi_params;
}
[...]
And for NodeJS you can also modify the same Vhost file
vi /etc/nginx/sites-available/default
and add lines below location ~ \.php$ {} stanza like
[...]
location /testapp/ {
proxy_pass http://localhost:3000/;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
[...]
from this you can forwarding port to Node.js app with Nginx
Now you can access the your page by this URL http://localhost/testapp/ instead of http://localhost:3000/

// when you create your object and assign it to a shared pointer register a cleanup function

Once the last reference expires "RecyleFunction" is called with your object as parameter. I use this pattern to recycle objects and insert them back into a pool.
A:
This would allow std::weak_ptr, who still refer to the deleted object,
to be cleaned up right in time.
Actually, they only hold weak references, which do not prevent the object from being destroyed. Holding weak_ptrs to an object does not prevent it's destruction or deletion in any fashion.
The quote you've given sounds to me like that guy just doesn't know which objects own which other objects, instead of having a proper ownership hierarchy where it's clearly defined how long everything lives.
As for boost::signals2, that's what a scoped_connection is for- i.e., you're doing it wrong.
The long and short is that there's nothing wrong with the tools in the Standard (except auto_ptr which is broken and bad and we have unique_ptr now). The problem is that you're not using them properly. | unknown | |

d7686 | train | The nn.Linear layer is a linear fully connected layer. It corresponds to wX+b, not sigmoid(WX+b).
As the name implies, it's a linear function. You can see it as a matrix multiplication (with or without a bias). Therefore it does not have an activation function (i.e. nonlinearities) attached.
If you want to append an activation function to it, you can do so by defining a sequential model:
model = nn.Sequential(
nn.Linear(2, 1)
nn.Sigmoid()
)
Edit - if you want to make sure:
x = torch.tensor([[0.2877, 0.2914]])
model = nn.Linear(2,1)
m1 = nn.Sequential(model, nn.Sigmoid())
m1(x)[0].item(), torch.sigmoid(model(x))[0].item()
A: Not surprisingly, PyTorch implements Linear as a linear function.
Why the sigmoid is not included?
*
*well, in that case it'd be weird to call the resultant module Linear, since the purpose of the sigmoid is to "break" the linearity: the sigmoid is a non-linear function;
*having a separate Linear module makes it possible to combine Linear with many activation functions other than the sigmoid, like the ReLU.
If the course says that a sigmoid is included in a "linear layer", that's a mistake (and I'd suggest you to change course). Maybe you're mistaking a linear layer for a "fully-connected layer". In practice, a fully-connected layer is made of a linear layer followed by a (non-linear) activation layer. | unknown | |
d7687 | train | You can use custom TypeAdapter in this case.
Example:
class ListWrapper<T> extends ArrayList<T>
{
private static final long serialVersionUID = 1L;
String id = "asd";
List<T> list = new ArrayList<T>();
transient T listener = null;
}
Create your custom TypeAdapter
class CustomTypeAdapter<T> extends TypeAdapter<ListWrapper<T>>
{
@Override
public void write(JsonWriter writer, ListWrapper<T> value) throws IOException
{
if (value == null)
{
writer.nullValue();
return;
}
writer.beginObject();
// Add id field
writer.name("id").value(value.id);
// Add list field
StringBuilder builder = new StringBuilder("");
builder.append("list : [ ");
for (T t : value.list)
{
builder.append("T : " + t.toString() + ",");
}
String txt = builder.substring(0, builder.length() - 1) + "]";
writer.name("list").value(StringUtils.join(value.list, ";"));
// Add other fields
// TODO
writer.endObject();
}
@Override
public ListWrapper<T> read(JsonReader in) throws IOException
{
// Implement your deserialization logic here
return null;
}
}
Sample usage:
public static void main(String[] args)
{
GsonBuilder builder = new GsonBuilder();
builder.registerTypeAdapter(ListWrapper.class, new CustomTypeAdapter<String>());
Gson gson = builder.create();
ListWrapper<String> lw = new ListWrapper<String>();
lw.list.add("as");

System.out.println(gson.toJson(lw));

d7688 | train | Take a careful read of the API docs for BatchWrite. It will answer your questions. Since you're not showing your batch code (are you using set? update?), we have to look at the API docs to assess the failure cases:
create()
This will fail the batch if a document exists at its location.
It sounds like you're probably not using create(), but this is the failure case.
set()
If the document does not exist yet, it will be created.
So, a set will not fail if the documented was deleted before the batch got committed.
update()
If the document doesn't yet exist, the update fails and the entire
batch will be rejected.
So, if you try to update a nonexistent document, the batch will fail.
If you want to decide what to do with each document, depending on its existence and contents, then control the failure cases, use a transaction.
A: If I understand your question, I had a similar scenario and here's how I did it. First, I use generated universal ID's, uid's, for all my item keys/id's. Then, what you do is on the grandchildren, simply write the uid of the parent it is associated with. Each grandchild could be associated with more than one parent.
As you create new items, you have to recursively update the parent with the uid of the item so the parent has record of all its associated child items.

d7689 | train | Seems like you're loading the whole content of your file into a byte[] directly in memory, then writing this in the OutputStream. The problem with this approach is that if you load files of 1 or 2 GBs entirely in memory then you will encounter with OutOfMemoryError quickly. To avoid this, you should read the data from InputStream in small chunks and write these chunks in the output stream. Here's an example for file downloading:
BufferedInputStream bis = new BufferedInputStream(
new FileInputStream(new File("/path/to/folder", "file.pdf")));
ServletOutputStream outStream = response.getOutputStream();
//to make it easier to change to 8 or 16 KBs
//make some tests to determine the best performance for your case

d7691 | train | One common approach is to put public header files in a include directory and the rest of the source files (both hpp and cpp) in a src directory. For example, suppose you're working on a project called foo. A possible file hierarchy would be the following:
foo
include
foo
x.hpp
y.hpp
src
x.cpp
y.cpp
z.cpp
z.hpp
In this case, you can simply add the include directory to the include path and you'll then be able to include the public header files like this: #include <foo/x.hpp>.
A: I want to share my ideas while I am not sure if I have the right answer:).
A:
*
*If the headers have complex inter-dependencies, it will be safer to simply install them all. Or you might want to read the source codes and clean the inter-dependencies.
*It is the right thing to put all the headers in one discretionary. :) | unknown | |
d7692 | train | From this post we can know:
.NET Core doesn't support inclusion of .NET Framework libraries. Period. However, .NET Core supports .NET Standard, and since .NET Framework also implements .NET Standard, Microsoft made a special exception in the compiler to allow you include .NET Framework libraries, with the caveat that they may not actually function at all or totally. You get a warning to this effect when you include a .NET Framework library in a .NET Core project, and it's on you to ensure that the library works correctly end-to-end.
Because .NET Core supports .NET Standard library, you can use the package of .NET Standard. This post is similar to your problem, his solution may inspire you. | unknown | |

d7694 | train | Thanks for making the effort of adding applescript support to your app! Just a quick observation / criticism: When constructing terminology, by all means include spaces, but if that terminology takes the form of 'verb noun' (like 'do update') appleScripters will be irritated if the noun 'update' is not a properly modelled object, and if 'do' is not a proper command.
I would argue that 'do' is a poor choice for a command name, because it is very vague. What's wrong with just using 'update' as the command? (i.e. treat it as a verb).
This issue is treated in some detail by Apple's own technote 2106 (currently here), which you definitely should read and digest if you hope to please your AppleScripting user community.
Apple themselves are not beyond stupid terminology choices such as updatePodcast and updateAllPodcasts (in iTunes). These are stupid choices because (according to tn2106) they contain no spaces, and because the better choice would be to have a proper podcast class and then have an update command which could be used on an individual podcast, all podcasts, or a particular chosen set of podcasts. | unknown | |
d7695 | train | You can get the data using -string, defined by NSText (e.g. NSString *savedString = [aTextView string])
Your save code can be put in your NSTextDelegate (read, delegate of the NSTextView, because it's the immediate superclass), in – textDidEndEditing: which will be called, well, when editing is finished (e.g. when the user clicks outside the view) or one of the other methods.
Then to reload the saved string if you emptied the text view or something, use [textView setString:savedString] before editing begins.
NSTextDelegate documentation: here.
I'm not sure what you mena when you say "store the contents of the box into a variable (array, etc.) Are you hoping for an array of custom notes? Text views store a string of data, so the easiest way of storing its value is using one string; if you need an array of notes you'd have to split the string value into different paragraphs, which shouldn't be too hard. | unknown | |
