d17401 | val | You can just call the DOM (not jQuery) form.submit() method, like this:
$("form")[0].submit();
Or if it's by ID:
document.getElementById('myForm').submit();
//or
$("#myForm").get(0).submit();
This bypasses the jQuery event handlers and prevents them from running, instead it directly submits the <form>. | unknown | |
d17402 | val | You should use the key label instead of name
label: '' + keys[n] + '', value: '' + dtData[keys[n]].length + '', | unknown | |
d17403 | val | what about this approach. not sure if {' '} in you code is necessary. this aligns with space between and looks better for the ui instead of giving a random space to separate the items. and also apply the rest oft he styles to your liking, for example make font bold, etc.
<FlatList
data={transaction_details}
ItemSeparatorComponent={this.FlatListItemSeparator}
renderItem={({ item }) => {
return (
<View>
<View style={{ flexDirection: 'row', justifyContent: 'space-between', alignItems: 'center' }}>
<Text>{item.narration}</Text>
<Text>{item.amount}</Text>

d17405 | val | First element
Second Element
Well its true that you are getting similar elements for that given xpath but you also have to go through their siblings/parents etc for different scenarios.
Here is the xpath I tried that identified the individual elements that you were looking for, are depicted above.
//div[@class='iradio_square-green']/input[@id='trip_0_date_0_flight_0_fare_0']/following-sibling::ins
For others radio buttons you just have to change the flight number.
Hope this helps...

d17406 | val | The primary reason for its existence is the introduction of anonymous types in C#. You can construct types on the fly that don't have a name. How would you specify their name? The answer: You can't. You just tell the compiler to infer them for you:
var user = users.Where(u=> u.Name == "Mehrdad")
.Select(u => new { u.Name, u.Password });
A: It's mostly present for LINQ, when you may use an anonymous type as the projection:
var query = from person in employees
where person.Salary > 10000m
select new { FullName=person.Name, person.Department };
Here the type of query can't be declared explicitly, because the anonymous type has no name. (In real world cases the anonymous type often includes values from multiple objects, so there's no one named class which contains all the properties.)
It's also practically useful when you're initializing a variable using a potentially long type name (usually due to generics) and just calling a constructor - it increases the information density (reduces redundancy). There's the same amount of information in these two lines:
List<Func<string, int>> functions = new List<Func<string, int>>();
var functions = new List<Function<string, int>>();
but the second one expresses it in a more compact way.
Of course this can be abused, e.g.
var nonObviousType = 999999999;
but when it's obvious what the type's variable is, I believe it can significantly increase readability.
A: It's a shorthand way of declaring a var. Although "int i = new int()" isn't too much to type, when you start getting to longer types, you end up with a lot of lines that look like:
SomeReallyLong.TypeName.WithNameSpaces.AndEverything myVar = new SomeReallyLong.TypeName.WithNameSpaces.AndEverything();
It eventually occurred to someone that the compiler already knew what type you were declaring thanks to the information you were using to initialize the var, so it wouldn't be too much to ask to just have the compiler do the right thing here.
A: *
*Linq expressions don't return a predefined type, so you need a 'generic' variable declaration keyword to capture that and other places where anonymous types are used.
*Used carefully, it can make refactoring easier by decoupling a method's return type from the variable that captures it.
*Having to put the same name on the same line twice for the same statement is really kind of silly. It's a pain to type something like this:
.
ReallyLongTypeName<SomeOtherLongTypeName> MyVariable = new ReallyLongTypeName<SomeOtherLongTypeName>();
A: Here are a couple of advantages
*
*Less typing with no loss of functionality
*Increases the type safety of your code. A foreach loop using an iteration variable which is typed to var will catch silently casts that are introduced with explicit types
*Makes it so you don't have to write the same name twice in a variable declaration.
*Some features, such as declaring a strongly typed anonymous type local variable, require the use of var
Shameless self promotion. I wrote a blog entry on this subject awhile back that dived into when I thought the use of var was appropriate and contains relative information to this topic.
*
*http://beta.blogs.msdn.com/jaredpar/archive/2008/09/09/when-to-use-type-inference.aspx
A: In short:
*
*minimize the need for typing the variable type twice
*essential in supporting anonymous types, e.g. as returned by LINQ queries
A: The real need for the var keyword was to support anonymous types in C# 3.0--which in turn were required to properly support LiNQ (Language Integrated Querying).
Without using var you could never do something like this:
var person = new { Name = "Peter", Age=4};
Which means that you couldn't execute execute the following linq query because you wouldn't know how to assign it to a variable:
[var/sometype] dogsFixedQuery = from myDog in kennel select new {dogName = myDog.FirstName + " " + myDog.OwnerLastName, myDog.IsNeutered, dogLocation = kennel.Address};
The utility of anonymous types will be more apparent if you start to create more complex linq queries with multiple levels of returns and joins.
The fact that you can use var in other ways to avoid typing out something like IEnumerable<Dictionary<List<string>,IOrderedCollection<DateTime>> myBadDesign = getBadDesignController().BadDesignResults("shoppingCart");
is just a side-effect/bonus in case you're a lazy typer =)
There are cons for readability if you start calling vars in disparate locations but if you're using var for a strong type and the compiler can determine the type of your variable than any reader should be able to determine it as well. | unknown | |
d17407 | val | To solve this problem you just need to create your segue from your viewController1 to your viewController2 and not from a button. This way you can trigger prepareForSegue programatically using the "performSegue" method that will call prepareForSegue anyway. | unknown | |
d17408 | val | This isn't exactly an answer, but here's a discussion of other people who have run into the same thing: https://github.com/vuejs/vue-router/issues/2932
It doesn't sound like there is a resolution, but since it appears harmless, (except for the message in the console), I'm going to not worry about it at the moment. | unknown | |
d17409 | val | The polygon2patch function certainly seems useful, but maybe for only drawing two rectangles, you could also use just two patch commands, and simply set the inner rectangle, i.e. the hole, to white foreground color, like so:
outer = [0 0; 2 0; 2 1; 0 1];
inner = [0.4 0.2; 1.6 0.2; 1.6 0.8; 0.4 0.8];
patch(outer(:, 1), outer(:, 2), 'c');
patch(inner(:, 1), inner(:, 2), 'w');
axis equal;
This will produce such an output:
Hope that helps! | unknown | |
d17410 | val | There is no infinite loop in your code above. It's quite possible that it is being called from an infinite loop.
To find this, place a breakpoint in the method, continue a few times (to ensure you're in the loop rather than just the normal calls) and then look at the stack trace on the side. This should give you a pretty clear idea of where the looping is coming from. You are probably calling reloadData from within one of your datasource or delegate methods. | unknown | |
d17411 | val | I think you need to provide the destination folder as a key and value, something like this(below)

d17414 | val | By defaults an IDE will use a layout manager to position components on the frame.
When you drag the panel you are manually setting the location of the panel and overriding the location determined by the layout manager.
However, when you resize the frame the layout manager code is again executed and the panel is set back to its original position.
You need to change your code so that the parent panel of the panel you drag uses a "null layout". However, when you do this you are now responsible for setting the size and location of the panel. | unknown | |
d17415 | val | Try this
$output .="<td ><strong><a href='users.php?username=" . $row['companyname']."'>". $row['companyname']."</a></strong></td>";
That should give you
<a href='users.php?username=John'>John</a> | unknown | |

d17417 | val | I think I've come up with a solution to your problem - it works in my environment but then I've had to guess how your code probably looks.
public static class ViewPageExtensions
{
public static MvcHtmlString GetIdFor<TViewModel, TProperty>(ViewPage<TViewModel> viewPage, Expression<Func<TViewModel, TProperty>> expression)
{
return viewPage.Html.IdFor(expression);
}
public static MvcHtmlString FocusScript<TViewModel>(this ViewPage<TViewModel> viewPage)
{
if (viewPage.ViewData["FieldToFocus"] == null)
return MvcHtmlString.Empty;
object expression = viewPage.ViewData["FieldToFocus"];
Type expressionType = expression.GetType(); // expressionType = Expression<Func<TViewModel, TProperty>>
Type functionType = expressionType.GetGenericArguments()[0]; // functionType = Func<TViewModel, TProperty>
Type[] functionGenericArguments = functionType.GetGenericArguments(); // functionGenericArguments = [TViewModel, TProperty]
System.Reflection.MethodInfo method = typeof(ViewPageExtensions).GetMethod("GetIdFor").MakeGenericMethod(functionGenericArguments); // method = GetIdFor<TViewModel, TProperty>
MvcHtmlString id = (MvcHtmlString)method.Invoke(null, new[] { viewPage, expression }); // Call GetIdFor<TViewModel, TProperty>(viewPage, expression);
return MvcHtmlString.Create(
@"<script type=""text/javascript"" language=""javascript"">
$(document).ready(function() {
setTimeout(function() {
$('#" + id + @"').focus();
}, 500);
});
</script>");
}
}
Perhaps there's a more elegant way to do, but I think what it boils down to is you're trying to cast an object (ie return type of ViewData["FieldToFocus"]) to the correct expression tree Expression<Func<TViewModel, TProperty>> but like you've said you don't know what TProperty should be.
Also to make this work I had to add another static method to GetIdFor because at the moment I'm not too sure how to invoke an extension method. Its just a wrapper to call the IdFor extension method.
You could make it less verbose (but probably less readable).
object expression = viewPage.ViewData["FieldToFocus"];
MethodInfo method = typeof(ViewPageExtensions).GetMethod("GetIdFor")
.MakeGenericMethod(expression.GetType().GetGenericArguments()[0].GetGenericArguments());
MvcHtmlString id = (MvcHtmlString)method.Invoke(null, new[] { viewPage, expression });
One final thought, would the output of HtmlHelper.IdFor ever differ from ExpressionHelper.GetExpressionText? I don't fully understand IdFor, and wonder if it will always give you a string that matches the property name.
ViewData["FieldToFocus"] = ExpressionHelper.GetExpressionText(fieldExpression);
A: It's as simple as using a LambdaExpression. No need to go the Expression<Func<TModel, TProperty>> way.
public static class HtmlExtensions
{
public static string IdFor(
this HtmlHelper htmlHelper,
LambdaExpression expression
)
{
var id = ExpressionHelper.GetExpressionText(expression);
return htmlHelper.ViewData.TemplateInfo.GetFullHtmlFieldId(id);
}
public static MvcHtmlString FocusScript(
this HtmlHelper htmlHelper
)
{
if (htmlHelper.ViewData["FieldToFocus"] != null)
{
return MvcHtmlString.Create(
@"<script type=""text/javascript"">
$(document).ready(function() {
setTimeout(function() {
$('#" + htmlHelper.IdFor((LambdaExpression)htmlHelper.ViewData["FieldToFocus"]) + @"').focus();
}, 500);
});
</script>");
}
else
{
return MvcHtmlString.Empty;
}
}
}
then in your controller:
public ActionResult Index()
{
FocusOnField((MyModel m) => m.IntProperty);
return View(new MyModel());
}
and in your view:
@model MyModel
@Html.FocusScript()
This being said I am leaving without comment the fact that a controller action is setting a focus.
A: You can take advantage of your out of the box Metadata to provide you the property Id etc..
And then in your Extensions:
public static MvcHtmlString FocusFieldFor<TModel, TValue>(
this HtmlHelper<TModel> html,
Expression<Func<TModel, TValue>> expression)
{
var metadata = ModelMetadata.FromLambdaExpression(expression, html.ViewData);
var fullPropertyName = html.ViewData.TemplateInfo.GetFullHtmlFieldId(metadata.PropertyName);
var jsonData =
@"<script type=""text/javascript"">
$(document).ready(function() {
setTimeout(function() {
$('#" + fullPropertyName + @"').focus();
}, 500);
});
</script>";
return MvcHtmlString.Create(jsonData);
}
A: Maybe I'm missing something, but since you're passing in the field name to your FocusOnField function, could you not also just pass the string of the field name as well which will be the default ID in the view then set a ViewData value? Then your javascript could do something like...
<script type="text/javascript">
onload = focusonme;
function focusonme() {
var element = document.getElementById(@ViewData["FieldToFocus"]);
element.focus();
}
</script>
Maybe this isn't exactly what you're after, but the JS will definitely work this way... | unknown | |

A: Thanks to @AzBakuFarid the main idea is to print every line of shapes from the top to the last together. @AzBakuFarid code had a very little mistake that you can see the corrected one below :
maximum = 10
a, b, c, d = 1, maximum, maximum, 1
while a <= maximum:
print('*'*a + ' '*(maximum-a) + ' '*2 + '*'*b + ' '*(maximum-b) + ' '*2 + ' '*(maximum-c) + '*'*c + ' '*2 + ' '*(maximum-d) + '*'*d)
a += 1
d += 1
b -= 1

As u wanted to be with for-loops I came up with this :
longest = int(input())
asterisk_a = 1
spaces_a = longest - 1
asterisk_b = longest
spaces_b = 0
asterisk_c = longest
spaces_c = 0
asterisk_d = 1

for i in range(0,longest):
print(asterisk_a * '*' + spaces_a * ' ' + ' ' + asterisk_b * '*' + spaces_b * ' ' + ' ' + spaces_c * ' ' + asterisk_c * '*' + ' ' + spaces_d * ' ' + asterisk_d * '*')
asterisk_a += 1
spaces_a -= 1
asterisk_b -= 1
spaces_b += 1
asterisk_c -= 1
spaces_c += 1
asterisk_d += 1
spaces_d -= 1

The goal of the concatenation is to have ALL Account Managers associated with that particular company in one cell so that that cell can be referenced in the table mentioned above, which appears on a separate sheet in this workbook; however, if that AM has made multiple sales for the same company, the formula still adds it to the final list, which can result in a list of "Bob, Joe, Bob, Tom, Bob" when I want to see "Bob, Joe, Tom".
The formula I use in the table to reference this list of AMs for each company is =LOOKUP(A5,'7.1.16 data'!A:A,'7.1.16 data'!C:C)
A: Just add a SEARCH query in your IF statement:
=IF(A2=A1,IF(ISNUMBER(SEARCH(B2, C1)), C1, C1 &", " & B2),B2)

d17436 | val | By manually setting the camera position in update, you're delaying the camera movement by at least one frame — physics runs after update, so your camera move happens on the frame after your character moves.
When you use a move action instead of directly setting the position, and giving that action a nonzero duration, you're delaying the camera move even more. (The dt in your code is the time between this frame and the last one before it, and you're applying that time to a future movement.) Because the character is still moving while your action runs, the camera will never catch up — you're always moving the camera to where the character was.
Setting the camera position at all is just making extra work for yourself, though. Use SKConstraint instead, and SpriteKit itself will make sure that the camera position sticks to the character — it solves constraints after physics, but on the same frame. | unknown | |
d17437 | val | You can use the css :hover selector..
Since you didn't specify the exact structure of your html its hard for me to say how exactly you should implement it.
Lets say for this matter that you want to show the on table mouse hover, and you table class is 'my-table'.
.my-table:hover{
th{
display:none;
}
}
You can read about the :hover selector here.
Edit:
If your html strauctre is something like:
<span class='my-toggle-span'>Toggle app filter!</span>
<app-filter class='my-app-filter'></app-filter>
Then your css will be
.my-toggle-span:hover +.my-app-filter{
display:none;
}
The plus selector Selects all element that are placed immediately after it.
Edit 2:
As opener requested, A javascript based solution:
I don't recommend this approach and any way, Your toggle logic should be handled in your component and not in your html.
<span class='my-toggle-span' (mouseenter)="toggle=true;"
(mouseleave)="toggle=false;">Toggle app filter!</span>
<app-filter *ngIf="toggle" class='my-app-filter'></app-filter> | unknown | |

UPDATE: My previous answer requires more css so I edited it. Based on the answer of jbutler, I got the idea about adding box-shadow to hide the corners. Nothing much changed on the original css I presented here, I just added the box-shadow. Updated fiddle HERE.
A: You can try using a white square block :before and :after the li.active a element, and positioning it so it's between the radius and the li:
ul li.active a:before,
ul li.active a:after {
content: "";
position: absolute;
background-color: white;
height: 11px;
width: 10px;
bottom: -1px;
}
ul li.active a:before {
left: -6px;
z-index: 1;
}
ul li.active a:after {
right: -6px;
background-color: white;
z-index: 6;
}
ul li.active:before {
left:-10px;
border-radius:8px 0;
border-width:0 1px 1px 0;
z-index: 5; // <<< This too
}
ul li.active:after {
right:-10px;
border-radius: 0 8px;
border-width:0 0 1px 1px;
z-index: 10; // <<< And here
}
http://jsfiddle.net/be5ceL9z/4/
This essentially just covers the square bottom corners of the li.active and #content elements by manipulating little square elements to cover them, but to be under the border-radius'd li.active:before and :after.
A more thorough explanation (courtesy atomictom's answer):
https://css-tricks.com/tabs-with-round-out-borders/
A: Here is an example of how this could be achieved with a combination of rotation and box shadows:
Initially, you have your rectangular div/element:
+---------+
| ELEMENT |
+---------+
From that, you can position a pseudo element either side of the bottom corners, with a border radius of 50% (to make a circle)
+---------+
| ELEMENT |
O+---------+O
Because I haven't set a background colour, you won't see this.
I've set a border on both, but then set three of the side colours to 'transparent' (so you only see one border).
Rotating this means that you can make the 'curved corner border' for each side:
+---------+
| ELEMENT |
)+---------+(
Using a box shadow then means you can hide the 'elements bottom corner' anyway:
+---------+
| ELEMENT |
) --------- (
Then setting the bottom border color to the active elelemtn itself means it is then 'hidden' anyway:
+---------+
| ELEMENT |
) ( <-- rotated slightly to create your corner

d17446 | val | You might be able to do it with textscan and repmat so you can avoid conversion from strings:

fclose(fid);

histogram = fileData{2}; % histogram(1,:) contains first file's features

d17447 | val | importPackage is originally from Rhino. Even Nashorn supports it when Rhino/Mozilla compatibility is requested explicitly using load("nashorn:mozilla_compat.js"); only, see Rhino Migration Guide in the documentation of Nashorn.
Graal.js has Nashorn compatibility mode and it supports load("nashorn:mozilla_compat.js"); in this mode.
So, you can use something like
System.setProperty("polyglot.js.nashorn-compat", "true");
ScriptEngine engine = new ScriptEngineManager().getEngineByName("graal.js");
System.out.println(engine.eval("load('nashorn:mozilla_compat.js'); importPackage('java.awt'); new Point();"));
(it prints java.awt.Point[x=0,y=0] which shows that the package java.awt was imported successfully). | unknown | |
d17448 | val | This is not really an answer, but more of a compilation of elements.
Reference :
The site http://www.cplusplus.com/ is clear: for the wprintf family : ... all format specifiers have the same meaning as in printf; therefore, %lc shall be used to write a wide character (and not %c), as well as %ls shall be used for wide strings (and not %s)
Implementations :
gcc and clang both conform to above specification
MSVC and according to OP Borland C++ do not conform and accept %s for a wide string.
A: I managed to find this in the vprinter.c file in the RTL source code (C++Builder comes with its own RTL, it doesn't reference MS):
/* The 's' conversion takes a string (char *) as
* argument and copies the string to the output
* buffer.
*
* Note: We must handle both narrow and wide versions
* depending on the flags specified and the version called:
*
* Format printf wprintf
* ----------------------------------------
* %s narrow wide
* %S wide narrow
* %hs narrow narrow
* %hS narrow narrow
* %ls wide wide
* %lS wide wide
*
*/
so the code:
swprintf(v, 50, L"%hs", "hello");
generates the correct output.
However, this doesn't do any UTF-8 conversion; narrow characters are "widened" by attaching a null byte. (Confirmed by inspecting the resut of the source). | unknown | |
d17449 | val | It looks like you want the set difference (that is, IPs in A that are not also in B), soooooo:
SELECT a.ip FROM tableA a WHERE tableA.ip NOT IN (SELECT b.ip FROM tableB)
A: Use NOT IN:
SELECT ip FROM TableA WHERE TableA.ip NOT IN (SELECT ip FROM TableB)
A: You can combine two result sets with UNION.
select ip from tableA
union
select ip from tableB;
http://dev.mysql.com/doc/refman/5.0/en/union.html
The default behavior is to remove duplicate rows.
If you want duplicate rows use UNION ALL.
A: select a.id from a minus select b.id from b
or
select a.id from a where a.id not in (select b.id from b)
A: SELECT col1, col2, .. , Ip from TableA
UNION
SELECT col, col2, ...., Ip from TableB
To get the differences you can use the MINUS Operator instead of UNION | unknown | |
d17450 | val | You can use from ... import ... statement:
from package.obj import obj
my_obj = obj()
A: Python is not Java. Feel free to put many classes into one file and then name the file according to the category:
import mypackage.image
this_image = image.png(...)
that_image = image.jpeg(....)
If your classes are so large you want them in separate files to ease the maintenance burden, that's fine, but you should not then inflict extra pain on your users (or yourself, if you use your own package ;). Gather your public classes in the package's __init__ file (or a category file, such as image) to present a fairly flat namespace:
mypackage's __init__.py (or image.py):
from _jpeg import jpeg
from _png import png
mypackage's _jpeg.py:
class jpeg(...):
...
mypackage's _png.py:
class png(...):
...
user code:
# if gathered in __init__
import mypackage
this_image = mypackage.png(...)
that_image = mypackage.jpeg(...)
or:
# if gathered in image.py
from mypackage import image
this_image = image.png(...)
that_image = image.jpeg(....)
A: Give your classes and modules meaningful names. That's the way. Name your module 'classes' and name your class 'MyClass'.
from package.classes import MyClass
myobj = MyClass() | unknown | |
d17451 | val | Your forgot the changes keyword. The correct syntax is
when transform $Body changes do (
print "moved"
)
A: An already key-framed node will not trigger this handler it is not being driven by the user, but by the system.
This will not trigger when you press play in the trackbar.
Without knowing exactly what you intend to do it's difficult to recommend an alternative.
If you wish to report the position or transform information of a specific node when the trackbar/currentTime changes, you could use registerTimeCallback and unRegisterTimeCallback .
fn reportObject =
(
print $Box001.pos
)
registerTimeCallback reportObject
This will trigger when the play button is used, or when you scrub the time bar. Read the documentation regarding timecallbacks as they have specific rules.
Hopefully this helps. | unknown | |
d17452 | val | You could create a new xsd:dateTime literal based on the original xsd:date literal.

d17461 | val | When you downloaded the program you probably got a .exe file, you need to execute this program with two command line arguments like so:
programname.exe word1 word2
If your friend didn't give you a executable file you need to compile the source into an executable. CodeBlocks provides this functionality and automatically runs the compiled result. Unfortunately it doesn't pass any arguments to the result which is why the program is telling you that it needs two words. (CodeBlocks is just executing programname.exe)
One solution to this problem is to configure code blocks to provide the arguments. As danben pointed out you can use the "Set program arguments" option in the "Project" menu to configure it to provide arguments. If you set your program arguments as word1 word2 then CodeBlocks will execute programname.exe word1 word2 which is what you want.
If you want to run this program elsewhere you need to compile it. Luckily whenever you click "run" in CodeBlocks it actually does compile an executable somewhere, typically in the project folder under bin\debug or bin\release you'll find a exectuable file. You can use this file as outlined above.
A: This is a question about CodeBlocks rather than about C++, but a quick Google search reveals that you need to select the "Set program arguments" option under the "Project" menu. | unknown | |
d17462 | val | Is there any advantage over the other?
The first really should be a val and not a var. Otherwise, they are equivalent. Or, to quote the documentation:
There are three ways to declare a MutableState object in a composable:
*
*val mutableState = remember { mutableStateOf(default) }
*var value by remember { mutableStateOf(default) }
*val (value, setValue) = remember { mutableStateOf(default) }
These declarations are equivalent, and are provided as syntax sugar for different uses of state. You should pick the one that produces the easiest-to-read code in the composable you're writing.
In those three:
*
*In the first, mutableState holds a MutableState, and you use .value and .value= to manipulate the contents
*In the second, value holds a MutableState, but the by syntax tells the compiler to treat it as a property delegate, so we can pretend that value just holds the underlying data
*In the third, a destructuring declaration gives you getter and setter references to manipulate the content in the underlying MutableState
A: The by in this context is a kotlin property delegate. Any class that implements the operator fun operator fun getValue(thisRef: Any?, prop: KProperty<*>): T can use this syntax. Using = will eagerly assign the variable (importantly without delegation), the by will delegate to the operator function. The remember in this case is just a shortcut function to creating the Remember delgate that wraps the value you are creating inside the { ... } block.
A typical example is the kotlin Lazy<T> class : val myValue : Int by lazy { 1 }. If used with the by operator you will return the Int value, if used with = it will return Lazy<Int> as you have not used delegation.
It is also worth noting that delgates can be setters as well by using this operator fun : operator fun setValue(thisRef: Any?, prop: KProperty<*>, value: T). | unknown | |

d17464 | val | With the default InProc session state, the application will terminate when the last session has expired, at which point Application_End occurs. In this scenario the entire appDomain is torn down and all memory freed. As sessions are persisted in memory they are permanently destroyed at this point, and therefore can never live beyond the life of the application.
If using Sql Server or State Server where the session is stored on a separate machine, then when the application is torn down the sessions can continue to live. Then because the client retains the original session cookie in the browser, the next time they visit the site the session is restarted, and sessionid used to identify their existing session.
A: Yes, when you put the state in SQL Server the application could restart but you will still maintain the session state | unknown | |
d17465 | val | I tried your code, and I put %SIZE(USRI00300) as the second parameter, and I got zero for suppGrpIdx too.
As Charles and Mark Sanderson implied, you have to make the receiver big enough to give all the information and also tell the API how big the receiver is. I'm guessing that since you defined your data structure as based, that you are setting p_usrData to some larger storage. If so, give the length of the larger storage instead of the size of USRI0300.
When I set p_usrData to point to a 32767-length buffer, and put %size(buffer) as the second parameter, I got 722 for suppGrpIdx. | unknown | |

d17469 | val | The regex issue can be answered with a simple negative assertion:
preg_replace('/(<(?!img)\w+[^>]+)(style="[^"]+")([^>]*)(>)/', '${1}${3}${4}', $article->text)
And a simpler approach might be using querypath (rather than fiddly DOMDocument):
FORACH htmlqp($html)->find("*")->not("img") EACH $el->removeAttr("style");
A: This does as you've asked
$string = '<img attribut="value" style="myCustom" attribut=\'value\' style=\'myCustom\' /> <input attribut="value" style="myCustom" attribut=\'value\' style=\'myCustom\'> <span attribut="value" style="myCustom" attribut=\'value\' style=\'myCustom\'> style= </span>';

d17470 | val | "2000-04-16T18:57" is not %d/%m/%Y %H:%M format but %Y-%m-%dT%H:%M format. Check list date formatters here https://docs.python.org/3/library/datetime.html#strftime-and-strptime-format-codes
A: Your widget format just show for client, not for Form.So you can try add a method named clean_date(self) to replace 'T' with whitespace then return it.
or add your format into DATETIME_INPUT_FORMATS list of settings.py.
A: i ended up managing to solve the problem, however I did not like the solution because it does not seem the most right ... however I will share it here in case people experience the same problem :)
What i did was:
create a copy of my GET so it becomes mutable
getCopy = request.GET.copy()
after that i converted the DATE that was comming from GET
ts = time.strptime(request.GET['date'], "%Y-%m-%dT%H:%M")
getCopy['date'] = time.strftime("%m/%d/%Y", ts)
and when i call my form.is_valid instead of passing request.GET, i pass my mutable copy of GET with my formatted date :) | unknown | |
d17471 | val | As said in the doc, the main differences are in how you are going to get an instance through Dependency Injection.
With Named Client you need to inject the factory and then get the client by a string.
var client = _clientFactory.CreateClient("github");
With Typed Client you can inject the client needed as a type.
//GitHubService encapsulate an HTTP client
public TypedClientModel(GitHubService gitHubService)
{
_gitHubService = gitHubService;
}
Both of them give the solution to your problem. The selection is more in how comfortable you are with the dependency injection method of each one. I personally prefer the Typed client. | unknown | |

function foo(){
var lList = $(".p1_lSelect");
var rList = $(".p1_rSelect");
bar(lList);
bar(rList);

function bar(list){
$(list).find("option:selected").each(function() {

d17476 | val | Follow these steps:
1- Change your itemChecked function to this
$scope.itemChecked = function(data) {
var selected = $scope.selectedItems.findIndex(function(itm) {
return itm == data.item
});
if (selected == -1) {
$scope.selectedItems.push(data.item);
} else {
$scope.selectedItems.splice(selected, 1);
}
};
2- Add an array for showing data after any filtering. Also add a function which filter your data according to input text:
$scope.filter = function() {
if (!$scope.searchField) {
$scope.data2Show = angular.copy($scope.data);
} else {
$scope.data2Show = [];
$scope.data.map(function(itm) {
if (itm.item.indexOf($scope.searchField) != -1) {
$scope.data2Show.push(itm);
}
});
}
};
$scope.data2Show = [];
Use this array to show items in list:
<li ng-repeat="data in data2Show">
3- Write a function to check if an item is selected or not and use:
$scope.isChecked = function (data) {
var selected = $scope.selectedItems.findIndex(function(itm) {
return itm == data.item;
});
if (selected == -1) {
return false;
} else {
return true;
}
}
And usage in html :
<input type="checkbox" ng-change="itemChecked(data)" name="select" ng-model="selectedItems" ng-checked="isChecked(data)">
4- Change checkbox ngModels from selectedItems to data.flag
ng-model="data.flag"
Final code:
var app = angular.module("myApp", []);
app.controller("myCtrl", function($scope, $http) {
$scope.selectEnable = false;
$scope.selectedItems = [];
$scope.openSelect = function() {
$scope.selectEnable = !$scope.selectEnable;
};
$scope.itemChecked = function(data) {
var selected = $scope.selectedItems.findIndex(function(itm) {
return itm == data.item;
});
if (selected == -1) {
$scope.selectedItems.push(data.item);
} else {
$scope.selectedItems.splice(selected, 1);
}
};
$scope.filter = function() {

if (itm.item.indexOf($scope.searchField) != -1) {
$scope.data2Show.push(itm);
}
});
}
};
$scope.isChecked = function(data) {
var selected = $scope.selectedItems.findIndex(function(itm) {
return itm == data.item;
});
if (selected == -1) {
return false;
} else {
return true;

Try to:
*
*composer update
*get sure you required vendor/autoload.php in your script | unknown | |
d17478 | val | Seems to me you are missing a semicolon after requiring the typeahead. | unknown | |
d17479 | val | Your first example is correct and absolutely should work:
var contacts = db.vMyView.OrderBy(c => c.LastName).ThenBy(c => c.FirstName);
// not sure why you need to reorder. Which could distort previous sorting
contacts = contacts.OrderBy(orderExpressions[sortExpression]).ThenBy(orderExpressions["FirstName"]);
Something looks off in your second example. OrderBy and ThenBy are already ascending there's no need for the additional parameter. There are alternatives for descending which are suffixed appropriately: OrderByDescending and ThenByDescending. | unknown | |
d17480 | val | I reckon you should be able to create a new scheme to run your UI Tests and uncheck unit tests from the Test action in Edit Scheme.
Later you can configure your new bot settings be specifying the UI Test scheme, selecting the "Perform test action" and select the iOS9 devices connected to your server.
You can continue to run unit tests with existing bot on all iOS devices and simulators. | unknown | |

A: Add a global variable in controller as scope.
Outside controller, add a variable (for example called: toggleVariable) and assign it to false.
Inside controller put this:
scope.toggleVariable = !scope.toggleVariable;
In HTML, add to ul tag: ng-show="toggleVariable".
Give it a try | unknown | |
d17483 | val | But how about declare a fundamental type (e.g., int, double or float)?
Declaring POD type objects won't cause an exception to be thrown.
Constructors of non-POD types can throw exceptions. Only the documents/source code of those types can help you figure out whether that will happen for a particular type.
A: It is the constructor of std::condition_variable that can throw an exception. Primitive types like int and double do not have any constructors. They simply have some stack space allocated for them and that's it, plus a value being written if you initialize the variable. The only way this could cause an exception is if you overflow the stack and the ensuing undefined behaviour happens to throw one.
A: POD types typically are initialized with initializer expressions instead of constructors. Like constructors, initializers can throw exceptions. But if you have neither a constructor nor an initializer, there's no code associated with the definition and therefore also no possibility for that code to throw. | unknown | |
d17484 | val | The FlatList component expects an array input for the data prop. Based on your JSON format, it appears you're passing in an object rather than an array.
Consider the following adjustment to your render method:
// Convert object to array based on it's values. If favPro not
// valid (ie during network request, default to an empty array)
const data = this.state.favPro ? Object.values(this.state.favPro) : []
<FlatList
data={data}
renderItem={this.fav}
keyExtractor={item => item.pro_id}
/>
A: You're using async / await incorrectly. Instead of calling .then you assign your call to await to a variable (or don't assign it if it does not return a value) and wrap the call (or calls) to await in a try / catch block. The await keyword will automatically handle resolve and reject so you get the appropriate information.
retrieveData = async () => {
try {
const data = JSON.parse(await AsyncStorage.getItem("userFavorites"))
this.setState({ favPro: data })
} catch (error) {
console.error(error)
this.setState({ favPro: [] })
}
}
You also need to pass an array, the shape of your data looks like an object, but it should be an array of objects. This is not a terribly difficult transformation and I can provide a helper function if you need it.
edit: if you need to convert an object into an array, you can use the reduce function
const data = {
'44': { a: 2 },
'55': { b: 3 },
}
const dataArr = Object.keys(data).reduce(
(arr, key) => arr.concat(data[key]),
[]
)
By using Object.keys we can each object by name. Then call reduce and the array returned by Object.keys, passing a function as the first argument, and an empty array as the second argument. The second argument is automatically passed to the function as the first argument, arr, and the second argument of the function we pass is the key of the object. Then it's just a matter of adding the objects to the array using concat.
Array.reduce can seem a little overwhelming at first but it's a very powerful method and you can get a lot done with it. | unknown | |

d17487 | val | For Basic Auth where the credentials are sent on each request it's expected.
In order for the ServiceClient to retain the Session cookies that have been authenticated you should set the RememberMe flag when you authenticate, e.g using CredentialsAuthProvider:
var client = new JsonServiceClient(BaseUrl);
var authResponse = client.Send(new Authenticate {
provider = "credentials",
UserName = "user",
Password = "p@55word",
RememberMe = true,

Behind the scenes this attaches the user session to the ss-pid cookie (permanent session cookie), which the client retains and resends on subsequent requests from that ServiceClient instance. | unknown | |

d17489 | val | Welcome to SO.
Although this is definitely not efficient for a small tuple, for a large one this will speed up the process greatly (from an O(n^2) solution to an O(n)). I hope this helps.
x = (2, 3, 4, 5)
y = ((2, 3), (3.5, 4.5), (6, 9), (4, 7))
for a, b in enumerate(y):
if b[0] <= x[a] <= b[1]:
print(f'{x[a]} is in between {b}.')
else:
print(f'{x[a]} is not in between {b}')
For boolean values:
interval = lambda t, i: [b[0] <= t[a] <= b[1] for a, b in enumerate(i)]
x = (2, 3, 4, 5)
y = ((2, 3), (3.5, 4.5), (6, 9), (4, 7))
print(interval(x, y))
All within linear (O(n)) time! Thanks for reading and have a great day.
A: You can achieve this in linear time using one loop.
You only have to iterate once on both of the tuples, something like this:
x = (2, 3, 4, 5)
y = ((2,3), (3.5, 4.5), (6, 9), (4, 7))
for index, number in enumerate(x):
if number > y[index][1] or number < y[index][0]:
print(f'{number} is NOT in {y[index}')
else:
print(f'{number} is in {y[index]}')
the output is:
2 is in the interval (2, 3)
3 is NOT in the interval (3.5, 4.5)
4 is NOT in the interval (6, 9)
5 is in the interval (4, 7)
As i said, this solution will take O(n), instead of O(n^2)
A: What about something like this
>>> x = (2, 3, 4, 5)
>>> y = ((2,3), (3.5, 4.5), (6, 9), (4, 7))
>>> def f(e):
... p, (q, r) = e
... return q <= p <= r
>>> list(map(f, zip(x,y)))

d17490 | val | By default, UIImageViews do not have user interaction enabled. Try setting your UIImageView's user interaction enabled to "YES":
[myImageView setUserInteractionEnabled:YES]; | unknown | |
d17491 | val | Indeed the expm's package does use exponentiation by squaring.
In pure r, this can be done rather efficiently like so,
"%^%" <- function(mat,power){
base = mat
out = diag(nrow(mat))
while(power > 1){
if(power %% 2 == 1){
out = out %*% base
}
base = base %*% base
power = power %/% 2
}
out %*% base
}
Timing this,
m0 <- diag(1, nrow=3,ncol=3)
system.time(replicate(10000, m0%^%4000))#expm's %^% function
user system elapsed
0.31 0.00 0.31
system.time(replicate(10000, m0%^%4000))# my %^% function
user system elapsed
0.28 0.00 0.28
So, as expected, they are the same speed because they use the same algorithm. It looks like the overhead of the looping r code does not make a significant difference.
So, if you don't want to use expm, and need that performance, then you can just use this, if you don't mind looking at imperative code.
A: A shorter solution with eigenvalue decomposition:
"%^%" <- function(S, power)
with(eigen(S), vectors %*% (values^power * t(vectors)))
A: If A is diagonizable, you could use eigenvalue decomposition:
matrix.power <- function(A, n) { # only works for diagonalizable matrices
e <- eigen(A)
M <- e$vectors # matrix for changing basis
d <- e$values # eigen values
return(M %*% diag(d^n) %*% solve(M))
}
When A is not diagonalizable, the matrix M (matrix of eigenvectors) is singular. Thus, using it with A = matrix(c(0,1,0,0),2,2) would give Error in solve.default(M) : system is computationally singular.
A: The expm package has an %^% operator:
library("sos")
findFn("{matrix power}")
install.packages("expm")
library("expm")
?matpow
set.seed(10);t(matrix(rnorm(16),ncol=4,nrow=4))->a
a%^%8
A: Although Reduce is more elegant, a for-loop solution is faster and seems to be as fast as expm::%^%
m1 <- matrix(1:9, 3)
m2 <- matrix(1:9, 3)
m3 <- matrix(1:9, 3)
system.time(replicate(1000, Reduce("%*%" , list(m1,m1,m1) ) ) )
# user system elapsed
# 0.026 0.000 0.037
mlist <- list(m1,m2,m3)
m0 <- diag(1, nrow=3,ncol=3)
system.time(replicate(1000, for (i in 1:3 ) {m0 <- m0 %*% m1 } ) )
# user system elapsed
# 0.013 0.000 0.014
library(expm) # and I think this may be imported with pkg:Matrix
system.time(replicate(1000, m0%^%3))
# user system elapsed
#0.011 0.000 0.017
On the other hand the matrix.power solution is much, much slower:
system.time(replicate(1000, matrix.power(m1, 4)) )
user system elapsed
0.677 0.013 1.037
@BenBolker is correct (yet again). The for-loop appears linear in time as the exponent rises whereas the expm::%^% function appears to be even better than log(exponent).
> m0 <- diag(1, nrow=3,ncol=3)
> system.time(replicate(1000, for (i in 1:400 ) {m0 <- m0 %*% m1 } ) )

d17493 | val | If i get it correct, your situation is as follows: You have, for example, one application (EXE) which uses a shared library (DLL). From both, the EXE and the DLL, you want to be able to log.
Last time i checked out the logog library i run in problems with the situation described above. Maybe now it is corrected?
Under windows (only!), the logog library doesn't export any symbols - it is simply not ready to be used as DLL. This forces you to build and use logog as static library - which leads to problems with static variables inside the logog library which should exist only once, but in reality are existing as many times as the static library was linked to a module (EXE or DLL).
The solution would be to build and use the logog library as DLL.
Maybe this covers your problem and you may take the effort to export the symbols of the logog library. Or you could get in contact with the library writer. | unknown | |
d17494 | val | Rather than extending ArrayBuffer[Person] directly, you can use the pimp my library pattern. The idea is to make Persons and ArrayBuffer[Person] completely interchangeable.
class Persons(val self: ArrayBuffer[Person]) extends Proxy {
def names = self map { _.name }
// ... other methods ...
}
object Persons {
def apply(ps: Person*): Persons = ArrayBuffer(ps: _*)
implicit def toPersons(b: ArrayBuffer[Person]): Persons = new Persons(b)
implicit def toBuffer(ps: Persons): ArrayBuffer[Person] = ps.self
}
The implicit conversion in the Persons companion object allows you to use any ArrayBuffer method whenever you have a Persons reference and vice-versa.
For example, you can do
val l = Persons(new Person("Joe"))
(l += new Person("Bob")).names
Note that l is a Persons, but you can call the ArrayBuffer.+= method on it because the compiler will automatically add in a call to Persons.toBuffer(l). The result of the += method is an ArrayBuffer, but you can call Person.names on it because the compiler inserts a call to Persons.toPersons.
Edit:
You can generalize this solution with higher-kinded types:
class Persons[CC[X] <: Seq[X]](self: CC[Person]) extends Proxy {
def names = self map (_.name)
def averageAge = {
self map (_.age) reduceLeft { _ + _ } /
(self.length toDouble)
}
// other methods
}
object Persons {
def apply(ps: Person*): Persons[ArrayBuffer] = ArrayBuffer(ps: _*)
implicit def toPersons[CC[X] <: Seq[X]](c: CC[Person]): Persons[CC] =
new Persons[CC](c)
implicit def toColl[CC[X] <: Seq[X]](ps: Persons[CC]): CC[Person] =
ps.self
}
This allows you to do things like
List(new Person("Joe", 38), new Person("Bob", 52)).names
or
val p = Persons(new Person("Jeff", 23))
p += new Person("Sam", 20)
Note that in the latter example, we're calling += on a Persons. This is possible because Persons "remembers" the underlying collection type and allows you to call any method defined in that type (ArrayBuffer in this case, due to the definition of Persons.apply).
A: Apart from anovstrup's solution, won't the example below do what you want?
case class Person(name: String, age: Int)
class Persons extends ArrayBuffer[Person]
object Persons {
def apply(ps: Person*) = {
val persons = new Persons
persons appendAll(ps)
persons
}
}

d17495 | val | Every render cycle the RenderComponent component is recreated, so it is mounted every render, and thus, mounts its children. Consider the following code where you render <Test /> directly, it's output is identical to {renderComponent()}.

const renderComponent = () => {
return <Test />;

The function renderComponent is executed and the return value is <Test />, thus equivalent to just rendering <Test /> directly, whereas RenderComponent is a new component each cycle.
A: When diffing two trees, React first compares the two root elements. The behavior is different depending on the types of the root elements.
Consider 3 cases:
{renderComponent()}
<RenderComponent />
<Test />
1) {renderComponent()}
Every render just return Test type, algorithm compares and sees that the type has not changed.
Result: mount Test component 1 time.
2) <RenderComponent />
Every render return new component type RenderComponent, algorithm compares and sees RenderComponent1 type != RenderComponent2 type, and:
Whenever the root elements have different types, React will tear down the old tree and build the new tree from scratch.
Result: mount child Test component 2 times.
Add console to mount RenderComponent:
const RenderComponent = () => {
useEffect(() => console.log('RenderComponent mount'), []);
return <Test />;
};
RenderComponent too mount 2 times.
3) <Test />
Similarly 1 case.
Result: mount Test component 1 time. | unknown | |

Here's a good tutorial on how to do that.The Constructor and Property approach is easier to implement.
You dont seem to be saving the orderid on the form1 class
Declare a variable for the OrderID on Form1 class
string OrderId;
Modify your exisiting Method
public string orderNumber()
{
OrderId = "ORD" + OrderId + DateTime.Now.Year;
}
And then follow the Constructor Approach to pass over the value to PrintForm
Again declare a variable for orderID inside the PrintForm class
string OrderId;
Change your PrintForm Constructor to this
public PrintForm(string value)
{
InitializeComponent();
OrderId=value;
}
on Form1 Button click event
private void button1_Click(object sender, System.EventArgs e)
{
PrintForm frm=new PrintForm(OrderId);
PrintForm.Show();
}
A: Create a container class with a static property in the same namespace:
class clsDummy
{
internal static string ptyValue { get; set; }
}
you can assign this property where you are getting order id:
public string orderNumber()
{
string ord = "ORD" + get_next_id() + DateTime.Now.Year;
clsDummy.ptyValue =ord ;
return ord;
}
after that where ever you want to access just check value inside : clsDummy.ptyValue | unknown |
