Make sure you added permission to write data in memory

If you are converting a varchar to int make sure you do not have decimal places.
For example, if you are converting a varchar field with value (12345.0) to an integer then you get this conversion error. In my case I had all my fields with .0 as ending so I used the following statement to globally fix the problem.
CONVERT(int, replace(FIELD_NAME,'.0',''))
Use a variable as an object key
let key = 'myKey';
let data = {[key] : 'name1'; }
I experienced this exception, and it was also related to ServicePointManager.SecurityProtocol
.
For me, this was because ServicePointManager.SecurityProtocol
had been set to Tls | Tls11
(because of certain websites the application visits with broken TLS 1.2) and upon visiting a TLS 1.2-only website (tested with SSLLabs' SSL Report), it failed.
An option for .NET 4.5 and higher is to enable all TLS versions:
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls
| SecurityProtocolType.Tls11
| SecurityProtocolType.Tls12;
I had this same problem, however mine was because I hadn't set the Server authentication to "SQL Server and Windows Authentication mode" (which you had) I just wanted to mention it here in case someone missed it in your question.

Yes.
It is a good practice since an element can be a part of different groups, and you may want specific elements to be a part of more than one group. The element can hold an infinite number of classes in HTML5, while in HTML4 you are limited by a specific length.
The following example will show you the use of multiple classes.
The first class makes the text color
red.
The second class makes the background-color
blue.
See how the DOM Element with multiple classes will behave, it will wear both CSS statements at the same time.
Result: multiple CSS statements in different classes will stack up.
You can read more about CSS Specificity.
.class1 {
color:red;
}
.class2 {
background-color:blue;
}

I found the following code the jQuery UI dialog function for open.
c([]).add(d.find(".ui-dialog-content :tabbable:first")).add(d.find(".ui-dialog-buttonpane :tabbable:first")).add(d).filter(":first").focus();
You can either workaround the jQuery behaviour or change the behaviour.
tabindex -1 works as a workaround.
The operations needed to be performed, require numpy arrays either created via
np.array()
or can be converted from list to an array via
np.stack()
As in the above mentioned case, 2 lists are inputted as operands it triggers the error.
Using Moment.js, you can get time and date like this:
var dateTimeString = moment(1439198499).format("DD-MM-YYYY HH:mm:ss");
And you can get only time using this:
var timeString = moment(1439198499).format("HH:mm:ss");
Another clean way to save the file is this:
import csv
import urllib
urllib.retrieve("your url goes here" , "output.csv")
$date = strtotime("+1 day");
echo date('m-d-y',$date);
The official Jenkins documentation only mentions single line commands like the following:
// Declarative //
and (see)
pipeline {
/* insert Declarative Pipeline here */
}
The syntax of the Jenkinsfile is based on Groovy so it is also possible to use groovy syntax for comments. Quote:
/* a standalone multiline comment
spanning two lines */
println "hello" /* a multiline comment starting
at the end of a statement */
println 1 /* one */ + 2 /* two */
or
/**
* such a nice comment
*/
in my case I needed something like this:
class JsonEncoder():
def encode(self, o):
if '_id' in o:
o['_id'] = str(o['_id'])
return o
For a read-only variable (that is, a constant value set once and used anywhere in the query), use a Common Table Expression (CTE).
WITH const AS (SELECT 'name' AS name, 10 AS more)
SELECT table.cost, (table.cost + const.more) AS newCost
FROM table, const
WHERE table.name = const.name
The more simple solution is provided in Eric Isaacs's answer. However, it will find constraints on any table. If you want to target a foreign key constraint on a specific table, use this:
IF EXISTS (SELECT *
FROM sys.foreign_keys
WHERE object_id = OBJECT_ID(N'dbo.FK_TableName_TableName2')
AND parent_object_id = OBJECT_ID(N'dbo.TableName')
)
ALTER TABLE [dbo.TableName] DROP CONSTRAINT [FK_TableName_TableName2]
You could build your own replace function using strstr to find the substrings and strncpy to copy in parts to a new buffer.
Unless what you want to replace_with
is the same length as what you you want to replace
, then it's probably best to use a new buffer to copy the new string to.

In OSX El Capitan update when you do this:
sudo ln -s /usr/local/mysql/lib/libmysqlclient.18.dylib /usr/lib/libmysqlclient.18.dylib
it throws an error like

So to avoid this, what you can do is first locate libmysqlclient.18.dylib
using the command
User$ locate libmysqlclient.18.dylib
In my case it returned /usr/local/mysql-5.5.24-osx10.5-x86_64/lib/libmysqlclient.18.dylib
So instead of usr/lib/
we will create symlink to usr/local/lib/

[1] My ticket about this issue; https://github.com/zonca/pytest-ipynb/issues/1
I have seen this question asked often and have come across this 'error' myself. There have even been links to question whether this is an actual bug in Chrome.
This is the response that occurs when one or more form input type elements are hidden and these elements have a min/max limit (or some other validation limitation) imposed.
On creation of a form, there are no values attributed to the elements, later on the element values may be filled or remain unchanged. At the time of submit, the form is parsed and any hidden elements that are outside of these validation limits will throw this 'error' into the console and the submit will fail. Since you can't access these elements (because they are hidden) this is the only response that is valid.
This isn't an actual fault nor bug. It is an indication that there are element values about to be submitted that are outside of the limits stipulated by one or more elements.
To fix this, assign a valid default value to any elements that are hidden in the form at any time before the form is submitted, then these 'errors' will never occur. It is not a bug as such, it is just forcing you into better programming habits.
NB: If you wish to set these values to something outside the validation limits then use form.addEventListener('submit', myFunction) to intercept the 'submit' event and fill in these elements in "myFunction". It seems the validation checking is performed before "myFunction() is called.
Download the appropriate APR based tomcat native library for your operating system so that Apache tomcat server can take some advantage of the feature of your OS which is not included by default in tomcat. For windows it will be a .dll

With SQL 2012 and later, you could use TRY_CAST
/TRY_CONVERT
to try converting to a numeric type, e.g. TRY_CAST(answer AS float) IS NOT NULL
-- note though that this will match scientific notation too (1+E34). (If you use decimal
, then scientific notation won't match)
You can also use percentages, and/or specify in the column headers:
<table width="300">
<tr>
<th width="20%">Column 1</th>
<th width="20%">Column 2</th>
<th width="20%">Column 3</th>
<th width="20%">Column 4</th>
<th width="20%">Column 5</th>
</tr>
<tr>
<!--- row data -->
</tr>
</table>
The bonus with percentages is lower code maintenance: you can change your table width without having to re-specify the column widths.
Caveat: It is my understanding that table width specified in pixels isn't supported in HTML 5; you need to use CSS instead.
The point of the google-services plugin is to simplify integration of Google features.
Since it only generates android-resources from the google-services.json file, over-complicated gradle-logic negates this point, I think.
So if the Google-docs don’t say which resources are needed for specific Google-features, I would suggest to generate the JSON-file for each relevant buildtype/flavor, see what resources get generated by the plugin and then put those resources manually into their respective src/buildtypeORflavor/res directories.
Delete the references to google-services plugin and the JSON-file after that, and you are done.
For detailed information about the inner workings of google-services gradle-plugin see my other answer:
Try this:
XmlDocument doc = new XmlDocument();
doc.Load(@"C:\Path\To\Xml\File.xml");
Or alternatively if you have the XML in a string use the LoadXml
method.
Once you have it loaded, you can use SelectNodes
and SelectSingleNode
to query specific values, for example:
XmlNode node = doc.SelectSingleNode("//Company/Email/text()");
// node.Value contains "[email protected]"
Finally, note that your XML is invalid as it doesn't contain a single root node. It must be something like this:
<Data>
<Employee>
<Name>Test</Name>
<ID>123</ID>
</Employee>
<Company>
<Name>ABC</Name>
<Email>[email protected]</Email>
</Company>
</Data>
Web APi 2 and later versions support a new type of routing, called attribute routing. As the name implies, attribute routing uses attributes to define routes. Attribute routing gives you more control over the URIs in your web API. For example, you can easily create URIs that describe hierarchies of resources.
For example:
[Route("customers/{customerId}/orders")]
public IEnumerable<Order> GetOrdersByCustomer(int customerId) { ... }
Will perfect and you don't need any extra code for example in WebApiConfig.cs. Just you have to be sure web api routing is enabled or not in WebApiConfig.cs , if not you can activate like below:
// Web API routes
config.MapHttpAttributeRoutes();
You don't have to do something more or change something in WebApiConfig.cs. For more details you can have a look this article.

Instead of CharSet.forName, using com.google.common.base.Charsets from Google's Guava (http://code.google.com/p/guava-libraries/wiki/StringsExplained#Charsets) is is slightly nicer:
InputStream is = new ByteArrayInputStream( myString.getBytes(Charsets.UTF_8) );
Which CharSet you use depends entirely on what you're going to do with the InputStream, of course.
Will return a floating point number in the range [0,1]:
#define rand01() (((double)random())/((double)(RAND_MAX)))
// The string must contain at least one special character, escaping reserved RegEx characters to avoid conflict
const hasSpecial = password => {
const specialReg = new RegExp(
'^(?=.*[!@#$%^&*"\\[\\]\\{\\}<>/\\(\\)=\\\\\\-_´+`~\\:;,\\.€\\|])',
);
return specialReg.test(password);
};
For Windows Forms you can control cursor position (and selection) with txtbox.SelectionStart
and txtbox.SelectionLength
properties. If you want to set caret to end try this:
txtbox.SelectionStart = txtbox.Text.Length;
txtbox.SelectionLength = 0;
For WPF see this question.
From a comment:
I want to sort each set.
That's easy. For any set s
(or anything else iterable), sorted(s)
returns a list of the elements of s
in sorted order:
>>> s = set(['0.000000000', '0.009518000', '10.277200999', '0.030810999', '0.018384000', '4.918560000'])
>>> sorted(s)
['0.000000000', '0.009518000', '0.018384000', '0.030810999', '10.277200999', '4.918560000']
Note that sorted
is giving you a list
, not a set
. That's because the whole point of a set, both in mathematics and in almost every programming language,* is that it's not ordered: the sets {1, 2}
and {2, 1}
are the same set.
You probably don't really want to sort those elements as strings, but as numbers (so 4.918560000 will come before 10.277200999 rather than after).
The best solution is most likely to store the numbers as numbers rather than strings in the first place. But if not, you just need to use a key
function:
>>> sorted(s, key=float)
['0.000000000', '0.009518000', '0.018384000', '0.030810999', '4.918560000', '10.277200999']
For more information, see the Sorting HOWTO in the official docs.

I've wrote this small script when the number of branches in my repo exceeded several hundreds. I did not know about the other methods (with CLI) so I decided to automate it with selenium. It simply opens Bitbucket website, goes to Branches, scrolls down the page to the end and clicks on every branch options menu -> clicks Delete button -> clicks Yes. It can be tuned to keep the last N (100 - default) branches and skip branches with specific names (master, develop - default, could be more). If this fits for you, you can try that way.

I used an authentication check followed by a sub called by a mediator class to the View (which also implements an authentication check) to write the password to the data class.
It's not a perfect solution; however, it remedied my problem of not being able to move the password.
I prefer to process collections functionally rather than mutate them in place. That avoids this kind of problem altogether, as well as aliasing issues and other tricky sources of bugs.
So, I would implement it like:
List<Thing> expand(List<Thing> inputs) {
List<Thing> expanded = new ArrayList<Thing>();
for (Thing thing : inputs) {
expanded.add(thing);
if (needsSomeMoreThings(thing)) {
addMoreThingsTo(expanded);
}
}
return expanded;
}
You just make div
s like this:
<div style="width:100px; height: 100px; border:1px solid; overflow:hidden; ">
<br/>
<div style="position:inherit; width: 200px; height:200px; background:yellow;">
<br/>
<div style="position:absolute; width: 500px; height:50px; background:Pink; z-index: 99;">
<br/>
</div>
</div>
</div>
I hope this code will help you :)
Strange behaviour which I was experienced also. So for me "return false" did the trick.
$( '#selector' ).on( 'click', function() {
//code
return false;
});

I really like those libraries mentioned here but I had an idea that could be simpler than just padding or doing tons of string manipulations,
You could just manually set your cursor using the maximum string length of your data. Here's some code to get the idea (not tested):
var column1[] = {"test", "longer test", "etc"}
var column2[] = {"data", "more data", "etc"}
var offset = strings.OrderByDescending(s => s.Length).First().Length;
for (var i = 0; i < column.Length; i++) {
Console.Write(column[i]);
Console.CursorLeft = offset + 1;
Console.WriteLine(column2[i]);
}
you could easily extrapolate if you have more rows.
It means that the standard now defines multi-threading, and it defines what happens in the context of multiple threads. Of course, people used varying implementations, but that's like asking why we should have a std::string
when we could all be using a home-rolled string
class.
When you're talking about POSIX threads or Windows threads, then this is a bit of an illusion as actually you're talking about x86 threads, as it's a hardware function to run concurrently. The C++0x memory model makes guarantees, whether you're on x86, or ARM, or MIPS, or anything else you can come up with.
Do you mean like this
int index = 2;
string s = "hello";
Console.WriteLine(s[index]);
string also implements IEnumberable<char>
so you can also enumerate it like this
foreach (char c in s)
Console.WriteLine(c);
If temp_rst1.BOF
and temp_rst1.EOF
then the recordset is empty. This will always be true for an empty recordset, linked or local.
You can't select a sheet in a non-active workbook.
You must first activate the workbook, then you can select the sheet.
workbooks("A").activate
workbooks("A").worksheets("B").select
When you use Activate it automatically activates the workbook.
Note you can select >1 sheet in a workbook:
activeworkbook.sheets(array("sheet1","sheet3")).select
but only one sheet can be Active, and if you activate a sheet which is not part of a multi-sheet selection then those other sheets will become un-selected.

I know this is an old question, but I haven't come across any answers that solved this problem for me so I'll provide my solution.
Note: I thought the issue may have been this, but my issue wasn't related to implementing the same interface twice. Using @Qualitier
did make my issue go away, but it was a bandage and not a proper solution so I didn't settle with that.
BACKGROUND
I'm tasked with maintaining an old project that has gone through different versions of spring and only updated for separate modules, so things needed refactoring, to say the least. I had initially gotten the duplicate bean issue and tinkering with things changed the issue back and forth between OP's issue and the duplicate bean issue even though there was only one bean; navigating to the duplicate beans always went to the same class.
THE ISSUE
The issue was present on a @Repository
class that was @Autowired
in a @Service
class which was also had the @ComponentScan
annotation. I noticed that I also had a spring application-config.xml
that was doing a context:component-scan
on the base package, which I believe was the original approach in older versions of Spring. I was in the process of making a new branch by taking parts of an old branch and a newer branch in a support project that was used in different projects that were developed over several years and that is why there was such a mix-and-match of methodologies.
SIMPLE SOLUTION
Since the more modern approach of using @ComponentScan
was already implemented I just removed the application-config.xml
and the issue was solved.
One more way of convenient placement of Environment.NewLine in format string. The idea is to create string extension method that formats string as usual but also replaces {nl} in text with Environment.NewLine
Usage
" X={0} {nl} Y={1}{nl} X+Y={2}".FormatIt(1, 2, 1+2);
gives:
X=1
Y=2
X+Y=3
Code
///<summary>
/// Use "string".FormatIt(...) instead of string.Format("string, ...)
/// Use {nl} in text to insert Environment.NewLine
///</summary>
///<exception cref="ArgumentNullException">If format is null</exception>
[StringFormatMethod("format")]
public static string FormatIt(this string format, params object[] args)
{
if (format == null) throw new ArgumentNullException("format");
return string.Format(format.Replace("{nl}", Environment.NewLine), args);
}
Note
If you want ReSharper to highlight your parameters, add attribute to the method above
[StringFormatMethod("format")]
This implementation is obviously less efficient than just String.Format
Maybe one, who interested in this question would be interested in the next question too: Named string formatting in C#
On windows 10 insert at beggining this:
#!/usr/bin/env python
# -*- coding: utf-8 -*-
Strange, but it work for me!(Together with input() at the end, of course)
1.) A local temporary table exists only for the duration of a connection or, if defined inside a compound statement, for the duration of the compound statement.
Local temp tables are only available to the SQL Server session or connection (means single user) that created the tables. These are automatically deleted when the session that created the tables has been closed. Local temporary table name is stared with single hash ("#") sign.
CREATE TABLE #LocalTemp
(
UserID int,
Name varchar(50),
Address varchar(150)
)
GO
insert into #LocalTemp values ( 1, 'Name','Address');
GO
Select * from #LocalTemp
The scope of Local temp table exist to the current session of current user means to the current query window. If you will close the current query window or open a new query window and will try to find above created temp table, it will give you the error.
2.) A global temporary table remains in the database permanently, but the rows exist only within a given connection. When connection is closed, the data in the global temporary table disappears. However, the table definition remains with the database for access when database is opened next time.
Global temp tables are available to all SQL Server sessions or connections (means all the user). These can be created by any SQL Server connection user and these are automatically deleted when all the SQL Server connections have been closed. Global temporary table name is stared with double hash ("##") sign.
CREATE TABLE ##GlobalTemp
(
UserID int,
Name varchar(50),
Address varchar(150)
)
GO
insert into ##GlobalTemp values ( 1, 'Name','Address');
GO
Select * from ##GlobalTemp
Global temporary tables are visible to all SQL Server connections while Local temporary tables are visible to only current SQL Server connection.
What am I doing incorrectly?
You have to convert html to javascript object, and then as a second step to json throug JSON.Stringify.
How can I receive a json object in the controller?
View:
<script src="https://code.jquery.com/jquery-3.1.0.js"></script>
<script src="https://raw.githubusercontent.com/marioizquierdo/jquery.serializeJSON/master/jquery.serializejson.js"></script>
var obj = $("#form1").serializeJSON({ useIntKeysAsArrayIndex: true });
$.post("http://localhost:52161/Default/PostRawJson/", { json: JSON.stringify(obj) });
<form id="form1" method="post">
<input name="OrderDate" type="text" /><br />
<input name="Item[0][Id]" type="text" /><br />
<input name="Item[1][Id]" type="text" /><br />
<button id="btn" onclick="btnClick()">Button</button>
</form>
Controller:
public void PostRawJson(string json)
{
var order = System.Web.Helpers.Json.Decode(json);
var orderDate = order.OrderDate;
var secondOrderId = order.Item[1].Id;
}
The view (blade template): Inside the loop you can retrieve whatever column you looking for
@foreach ($products as $product)
{{$product->sku}}
@endforeach
It's not free or open source. But you can give Intellij Idea's SWING GUI designer a try.
Here is the optimized code snippet to remove empty arrays/objects as well:
function removeNullsInObject(obj) {
if( typeof obj === 'string' ){ return; }
$.each(obj, function(key, value){
if (value === "" || value === null){
delete obj[key];
} else if ($.isArray(value)) {
if( value.length === 0 ){ delete obj[key]; return; }
$.each(value, function (k,v) {
removeNullsInObject(v);
});
} else if (typeof value === 'object') {
if( Object.keys(value).length === 0 ){
delete obj[key]; return;
}
removeNullsInObject(value);
}
});
}
Thanks @Alexis king :)
I used the built in jQuery.serialize() to extract the value from a textarea to urlencode the input. The pro part is that you don't have to search replace every special char on your own and i also keep the newlines and escapes html. For serialize to work it seems the input field needs to have a name attribute though and it also adds same attribute to the escaped string which needs to be replaced away. Might not be what you are looking for but it works for me.
var myinputfield = jQuery("#myinputfield");
var text = myinputfield.serialize();
text = text.replace(myinputfield.attr('name') + '=','');
You can use multiple ordering on multiple condition,
ORDER BY
(CASE
WHEN @AlphabetBy = 2 THEN [Drug Name]
END) ASC,
CASE
WHEN @TopBy = 1 THEN [Rx Count]
WHEN @TopBy = 2 THEN [Cost]
WHEN @TopBy = 3 THEN [Revenue]
END DESC
It's a bit late but I came across this post.
It's not perfect but here's what I do.
HTML Code
<div class="showcase-menu-social"><img class="margin-left-20" src="images/graphics/facebook-50x50.png" alt="facebook-50x50" width="50" height="50" /><img class="margin-left-20" src="images/graphics/twitter-50x50.png" alt="twitter-50x50" width="50" height="50" /><img class="margin-left-20" src="images/graphics/youtube-50x50.png" alt="youtube-50x50" width="50" height="50" /></div>
CSS Code
.showcase-menu {
margin-left:20px;
margin-right:20px;
padding: 0px 20px 0px 20px;
background-color: #C37500;
behavior: url(/css/border-radius.htc);
border-radius: 20px;
}
.showcase-menu-social img:hover {
background-color: #C37500;
opacity:0.7 !important;
filter:alpha(opacity=70) !important; /* For IE8 and earlier */
box-shadow: 0 0 0px #000000 !important;
}
Now my border radius of 20px matches up exactly with the image border radius. As you can see the .showcase-menu has the same background as the .showcase-menu-social. What this does is to allow the 'opacity' to take effect and no 'square' background or border shows, thus the image slightly reduces it's saturation on hover.
It's a nice effect and does give the viewer the feedback that the image is in focus. I'm fairly sure on a darker background, it would have even a better effect.
The nice thing is that this is valid HTML-CSS code and will validate. To be honest, it should work on non-image elements just as good as images.
Enjoy!
If you are using, Putty session, then it automatically copies selection. If we have used "set mouse=a" option in vim, selecting using Shift+Mouse drag selects the text automatically. Need to check in X-term.
To declare it:
var myArr = ["apples", "oranges", "bananas"];
To use it:
document.write("In my shopping basket I have " + myArr[0] + ", " + myArr[1] + ", and " + myArr[2]);
If you add double paranthesis to the ngModel reference you get a two-way binding to your model property. That property can then be read and used in the event handler. In my view that is the most clean approach.
<input type="checkbox" [(ngModel)]="myModel.property" (ngModelChange)="processChange()" />
This makes me wonder, when is it advisable to use the EntityManager.getReference() method instead of the EntityManager.find() method?
EntityManager.getReference()
is really an error prone method and there is really very few cases where a client code needs to use it.
Personally, I never needed to use it.
I disagree with the accepted answer and particularly :
If i call find method, JPA provider, behind the scenes, will call
SELECT NAME, AGE FROM PERSON WHERE PERSON_ID = ? UPDATE PERSON SET AGE = ? WHERE PERSON_ID = ?
If i call getReference method, JPA provider, behind the scenes, will call
UPDATE PERSON SET AGE = ? WHERE PERSON_ID = ?
It is not the behavior that I get with Hibernate 5 and the javadoc of getReference()
doesn't say such a thing :
Get an instance, whose state may be lazily fetched. If the requested instance does not exist in the database, the EntityNotFoundException is thrown when the instance state is first accessed. (The persistence provider runtime is permitted to throw the EntityNotFoundException when getReference is called.) The application should not expect that the instance state will be available upon detachment, unless it was accessed by the application while the entity manager was open.
EntityManager.getReference()
spares a query to retrieve the entity in two cases :
1) if the entity is stored in the Persistence context, that is
the first level cache.
And this behavior is not specific to EntityManager.getReference()
,
EntityManager.find()
will also spare a query to retrieve the entity if the entity is stored in the Persistence context.
You can check the first point with any example.
You can also rely on the actual Hibernate implementation.
Indeed, EntityManager.getReference()
relies on the createProxyIfNecessary()
method of the org.hibernate.event.internal.DefaultLoadEventListener
class to load the entity.
Here is its implementation :
private Object createProxyIfNecessary(
final LoadEvent event,
final EntityPersister persister,
final EntityKey keyToLoad,
final LoadEventListener.LoadType options,
final PersistenceContext persistenceContext) {
Object existing = persistenceContext.getEntity( keyToLoad );
if ( existing != null ) {
// return existing object or initialized proxy (unless deleted)
if ( traceEnabled ) {
LOG.trace( "Entity found in session cache" );
}
if ( options.isCheckDeleted() ) {
EntityEntry entry = persistenceContext.getEntry( existing );
Status status = entry.getStatus();
if ( status == Status.DELETED || status == Status.GONE ) {
return null;
}
}
return existing;
}
if ( traceEnabled ) {
LOG.trace( "Creating new proxy for entity" );
}
// return new uninitialized proxy
Object proxy = persister.createProxy( event.getEntityId(), event.getSession() );
persistenceContext.getBatchFetchQueue().addBatchLoadableEntityKey( keyToLoad );
persistenceContext.addProxy( keyToLoad, proxy );
return proxy;
}
The interesting part is :
Object existing = persistenceContext.getEntity( keyToLoad );
2) If we don't effectively manipulate the entity, echoing to the lazily fetched of the javadoc.
Indeed, to ensure the effective loading of the entity, invoking a method on it is required.
So the gain would be related to a scenario where we want to load a entity without having the need to use it ? In the frame of applications, this need is really uncommon and in addition the getReference()
behavior is also very misleading if you read the next part.
In terms of overhead, getReference()
is not better than find()
as discussed in the previous point.
So why use the one or the other ?
Invoking getReference()
may return a lazily fetched entity.
Here, the lazy fetching doesn't refer to relationships of the entity but the entity itself.
It means that if we invoke getReference()
and then the Persistence context is closed, the entity may be never loaded and so the result is really unpredictable. For example if the proxy object is serialized, you could get a null
reference as serialized result or if a method is invoked on the proxy object, an exception such as LazyInitializationException
is thrown.
It means that the throw of EntityNotFoundException
that is the main reason to use getReference()
to handle an instance that does not exist in the database as an error situation may be never performed while the entity is not existing.
EntityManager.find()
doesn't have the ambition of throwing EntityNotFoundException
if the entity is not found. Its behavior is both simple and clear. You will never have surprise as it returns always a loaded entity or null
(if the entity is not found) but never an entity under the shape of a proxy that may not be effectively loaded.
So EntityManager.find()
should be favored in the very most of cases.
I think init_js should use declare instead of local!
function scan3() {
declare -n outvar=$1 # -n makes it a nameref.
local nl=$'\x0a'
outvar="output${nl}${nl}" # two total. quotes preserve newlines
}

Assuming that by "binary code" you mean just plain old data (sequences of bits, or bytes), and that by "letters" you mean characters, the answer is in two steps. But first, some background.
Okay now here are the two steps:
The data, if it is textual, must be accompanied somehow by a character encoding, something like UTF-8, Latin-1, US-ASCII, etc. Each character encoding scheme specifies in great detail how byte sequences are interpreted as codepoints (and conversely how codepoints are encoded as byte sequences).
Once the byte sequences are interpreted as codepoints, you have your characters, because each character has a specific codepoint.
A couple notes:
In other words, not every byte sequence means something as text.
Converting your lists to sets will tell you that they contain the same elements. But this method cannot confirm that they contain the same number of all elements. For example, your method will fail in this case:
L1 = [1,2,2,3]
L2 = [1,2,3,3]
You are likely better off sorting the two lists and comparing them:
def checkEqual(L1, L2):
if sorted(L1) == sorted(L2):
print "the two lists are the same"
return True
else:
print "the two lists are not the same"
return False
Note that this does not alter the structure/contents of the two lists. Rather, the sorting creates two new lists

Well the correct answer for the default Json formater based on Json.net is to set ReferenceLoopHandling
to Ignore
.
Just add this to the Application_Start
in Global.asax:
HttpConfiguration config = GlobalConfiguration.Configuration;
config.Formatters.JsonFormatter
.SerializerSettings
.ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore;
This is the correct way. It will ignore the reference pointing back to the object.
Other responses focused in changing the list being returned by excluding data or by making a facade object and sometimes that is not an option.
Using the JsonIgnore
attribute to restrict the references can be time consuming and if you want to serialize the tree starting from another point that will be a problem.
1- Traditional way
The traditional conversion way is through using read() method of InputStream as the following:
public static byte[] convertUsingTraditionalWay(File file)
{
byte[] fileBytes = new byte[(int) file.length()];
try(FileInputStream inputStream = new FileInputStream(file))
{
inputStream.read(fileBytes);
}
catch (Exception ex)
{
ex.printStackTrace();
}
return fileBytes;
}
2- Java NIO
With Java 7, you can do the conversion using Files utility class of nio package:
public static byte[] convertUsingJavaNIO(File file)
{
byte[] fileBytes = null;
try
{
fileBytes = Files.readAllBytes(file.toPath());
}
catch (Exception ex)
{
ex.printStackTrace();
}
return fileBytes;
}
3- Apache Commons IO
Besides JDK, you can do the conversion using Apache Commons IO library in 2 ways:
3.1. IOUtils.toByteArray()
public static byte[] convertUsingIOUtils(File file)
{
byte[] fileBytes = null;
try(FileInputStream inputStream = new FileInputStream(file))
{
fileBytes = IOUtils.toByteArray(inputStream);
}
catch (Exception ex)
{
ex.printStackTrace();
}
return fileBytes;
}
3.2. FileUtils.readFileToByteArray()
public static byte[] convertUsingFileUtils(File file)
{
byte[] fileBytes = null;
try
{
fileBytes = FileUtils.readFileToByteArray(file);
}
catch(Exception ex)
{
ex.printStackTrace();
}
return fileBytes;
}
Download the driver JAR from the link provided by Olaf and add it to your local Maven repository with;
mvn install:install-file -Dfile=sqljdbc4.jar -DgroupId=com.microsoft.sqlserver -DartifactId=sqljdbc4 -Dversion=4.0 -Dpackaging=jar
Then add it to your project with;
<dependency>
<groupId>com.microsoft.sqlserver</groupId>
<artifactId>sqljdbc4</artifactId>
<version>4.0</version>
</dependency>
As far as I can tell, at this point it is not possible to set click_action in the console.
While not a strict answer to how to get the click_action set in the console, you can use curl as an alternative:
curl --header "Authorization: key=<YOUR_KEY_GOES_HERE>" --header Content-Type:"application/json" https://fcm.googleapis.com/fcm/send -d "{\"to\":\"/topics/news\",\"notification\": {\"title\": \"Click Action Message\",\"text\": \"Sample message\",\"click_action\":\"OPEN_ACTIVITY_1\"}}"
This is an easy way to test click_action mapping. It requires an intent filter like the one specified in the FCM docs:
<intent-filter>_x000D_
<action android:name="OPEN_ACTIVITY_1" />_x000D_
<category android:name="android.intent.category.DEFAULT" />_x000D_
</intent-filter>
_x000D_
This also makes use of topics to set the audience. In order for this to work you will need to subscribe to a topic called "news".
FirebaseMessaging.getInstance().subscribeToTopic("news");
Even though it takes several hours to see a newly-created topic in the console, you may still send messages to it through the FCM apis.
Also, keep in mind, this will only work if the app is in the background. If it is in the foreground you will need to implement an extension of FirebaseMessagingService. In the onMessageReceived method, you will need to manually navigate to your click_action target:
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
//This will give you the topic string from curl request (/topics/news)
Log.d(TAG, "From: " + remoteMessage.getFrom());
//This will give you the Text property in the curl request(Sample Message):
Log.d(TAG, "Notification Message Body: " + remoteMessage.getNotification().getBody());
//This is where you get your click_action
Log.d(TAG, "Notification Click Action: " + remoteMessage.getNotification().getClickAction());
//put code here to navigate based on click_action
}
As I said, at this time I cannot find a way to access notification payload properties through the console, but I thought this work around might be helpful.
I would not use an array in this case. Instead I would use a StringCollection.
using System.Collections.Specialized;
private StringCollection ColeccionDeCortes(string Path)
{
DirectoryInfo X = new DirectoryInfo(Path);
FileInfo[] listaDeArchivos = X.GetFiles();
StringCollection Coleccion = new StringCollection();
foreach (FileInfo FI in listaDeArchivos)
{
Coleccion.Add( FI.Name );
}
return Coleccion;
}
I've done this, it works on every device I tested, and even on emulators:
// Return the NavigationBar height in pixels if it is present, otherwise return 0
public static int getNavigationBarHeight(Activity activity) {
Rect rectangle = new Rect();
DisplayMetrics displayMetrics = new DisplayMetrics();
activity.getWindow().getDecorView().getWindowVisibleDisplayFrame(rectangle);
activity.getWindowManager().getDefaultDisplay().getRealMetrics(displayMetrics);
return displayMetrics.heightPixels - (rectangle.top + rectangle.height());
}
Running example of how it works:
var e = document.getElementById("ddlViewBy");_x000D_
var val1 = e.options[e.selectedIndex].value;_x000D_
var txt = e.options[e.selectedIndex].text;_x000D_
_x000D_
document.write("<br />Selected option Value: "+ val1);_x000D_
document.write("<br />Selected option Text: "+ txt);
_x000D_
<select id="ddlViewBy">_x000D_
<option value="1">test1</option>_x000D_
<option value="2">test2</option>_x000D_
<option value="3" selected="selected">test3</option>_x000D_
</select>
_x000D_
Note: The values don't change as the dropdown is changed, if you require that functionality then an onClick change is to be implemented.
You should learn the raise statement of python for that. It should be kept inside the try block. Example -
try:
raise TypeError #remove TypeError by any other error if you want
except TypeError:
print('TypeError raised')

I only use MicrosoftAdvertising.Mobile and Microsoft.Advertising.Mobile.UI and I am served ads. The SDK should only add the DLLs not reference itself.
Note: You need to explicitly set width and height Make sure the phone dialer, and web browser capabilities are enabled
Followup note: Make sure that after you've removed the SDK DLL, that the xmlns references are not still pointing to it. The best route to take here is
Here is the xmlns reference:
xmlns:AdNamepace="clr-namespace:Microsoft.Advertising.Mobile.UI;assembly=Microsoft.Advertising.Mobile.UI"
Then the ad itself:
<AdNamespace:AdControl x:Name="myAd" Height="80" Width="480" AdUnitId="yourAdUnitIdHere" ApplicationId="yourIdHere"/>
SELECT p.Name, v.Name
FROM Production.Product p
JOIN Purchasing.ProductVendor pv
ON p.ProductID = pv.ProductID
JOIN Purchasing.Vendor v
ON pv.BusinessEntityID = v.BusinessEntityID
WHERE ProductSubcategoryID = 15
ORDER BY v.Name;
You can use !setup.py install
to do that.
Colab is just like a Jupyter notebook. Therefore, we can use the !
operator here to install any package in Colab. What !
actually does is, it tells the notebook cell that this line is not a Python code, its a command line script. So, to run any command line script in Colab, just add a !
preceding the line.
For example: !pip install tensorflow
. This will treat that line (here pip install tensorflow
) as a command prompt line and not some Python code. However, if you do this without adding the !
preceding the line, it'll throw up an error saying "invalid syntax".
But keep in mind that you'll have to upload the setup.py
file to your drive before doing this (preferably into the same folder where your notebook is).
Hope this answers your question :)
In my angular app the following style worked for me to achieve ellipsis on the overflow of text on the second line:
<div style="height:45px; overflow: hidden; position: relative;">
<span class=" block h6 font-semibold clear" style="overflow: hidden;
text-overflow: ellipsis;
display: -webkit-box;
line-height: 20px; /* fallback */
max-height: 40px; /* fallback */
-webkit-line-clamp: 2; /* number of lines to show */
-webkit-box-orient: vertical;">
{{ event?.name}} </span>
</div>
Hope it helps someone.
Use COALESCE
, which returns the first not-null value e.g.
SELECT COALESCE(sum(case when c.runstatus = 'Succeeded' then 1 end), 0) as Succeeded
Will set Succeeded as 0 if it is returned as NULL
.
As a general rule, I'd always advocate explicitly calling the Dispose method for any class that offers it, either by calling the method directly or wrapping in a "using" block.
Most often, classes that implement IDisposible do so because they wrap some unmanaged resource that needs to be freed. While these classes should have finalizers that act as a safeguard, calling Dispose will help free that memory earlier and with lower overhead.
In the case of the Form object, as the link fro Kyra noted, the Close method is documented to invoke Dispose on your behalf so you need not do so explicitly. However, to me, that has always felt like relying on an implementaion detail. I prefer to always call both Close and Dispose for classes that implement them, to guard against implementation changes/errors and for the sake of being clear. A properly implemented Dispose method should be safe to invoke multiple times.

string Serialise<T>(T serialisableObject)
{
var xmlSerializer = new XmlSerializer(serialisableObject.GetType());
using (var ms = new MemoryStream())
{
using (var xw = XmlWriter.Create(ms,
new XmlWriterSettings()
{
Encoding = new UTF8Encoding(false),
Indent = true,
NewLineOnAttributes = true,
}))
{
xmlSerializer.Serialize(xw,serialisableObject);
return Encoding.UTF8.GetString(ms.ToArray());
}
}
}
The solution with FileWriter
is working, however you have no possibility to specify output encoding then, in which case the default encoding for machine will be used, and this is usually not UTF-8!
So at best use FileOutputStream
:
Writer writer = new BufferedWriter(new OutputStreamWriter(
new FileOutputStream(file, true), "UTF-8"));
One way is to loop through the keys of the dictionary, which I recommend:
foreach(int key in sp.Keys)
dynamic value = sp[key];
Another way, is to loop through the dictionary as a sequence of pairs:
foreach(KeyValuePair<int, dynamic> pair in sp)
{
int key = pair.Key;
dynamic value = pair.Value;
}
I recommend the first approach, because you can have more control over the order of items retrieved if you decorate the Keys
property with proper LINQ statements, e.g., sp.Keys.OrderBy(x => x)
helps you retrieve the items in ascending order of the key. Note that Dictionary
uses a hash table data structure internally, therefore if you use the second method the order of items is not easily predictable.

import { HttpClientModule } from '@angular/common/http';
The HttpClient API was introduced in the version 4.3.0. It is an evolution of the existing HTTP API and has it's own package @angular/common/http. One of the most notable changes is that now the response object is a JSON by default, so there's no need to parse it with map method anymore .Straight away we can use like below
http.get('friends.json').subscribe(result => this.result =result);
value = value.setScale(2, RoundingMode.CEILING)
I know this question was already answered, but this is what I use:
using (FileStream fStream = File.OpenRead(filename)) {
return GetHash<MD5>(fStream)
}
Where GetHash:
public static String GetHash<T>(Stream stream) where T : HashAlgorithm {
StringBuilder sb = new StringBuilder();
MethodInfo create = typeof(T).GetMethod("Create", new Type[] {});
using (T crypt = (T) create.Invoke(null, null)) {
byte[] hashBytes = crypt.ComputeHash(stream);
foreach (byte bt in hashBytes) {
sb.Append(bt.ToString("x2"));
}
}
return sb.ToString();
}
Probably not the best way, but it can be handy.

I tried several things to solve it (ie changing the encoding, typing the XML file rather than copy-pasting it ect) in Notepad and XML Notepad but nothing worked.
The problem got solved when I edited and saved my XML file in Notepad++ (encoding --> utf-8 without BOM)
In Three.js R66, this is what I use (CoffeeScript version):
THREE.Object3D.prototype.rotateAroundWorldAxis = (axis, radians) ->
rotWorldMatrix = new THREE.Matrix4()
rotWorldMatrix.makeRotationAxis axis.normalize(), radians
rotWorldMatrix.multiply this.matrix
this.matrix = rotWorldMatrix
this.rotation.setFromRotationMatrix this.matrix
I'm using XAMPP 1.6.7 on Windows 7. This article worked for me.
I added the following lines in the file httpd-vhosts.conf
at C:/xampp/apache/conf/extra
.
I had also uncommented the line # NameVirtualHost *:80
<VirtualHost mysite.dev:80>
DocumentRoot "C:/xampp/htdocs/mysite"
ServerName mysite.dev
ServerAlias mysite.dev
<Directory "C:/xampp/htdocs/mysite">
Order allow,deny
Allow from all
</Directory>
</VirtualHost>
After restarting the apache, it were still not working.
Then I had to follow the step 9 mentioned in the article by editing the file C:/Windows/System32/drivers/etc/hosts
.
# localhost name resolution is handled within DNS itself.
127.0.0.1 localhost
::1 localhost
127.0.0.1 mysite.dev
Then I got working http://mysite.dev
Script snip below creates a pause sub that displayes the pause text in a string and waits for the Enter key. z can be anything. Great if multilple user intervention required pauses are needed. I just keep it in my standard script template.

WScript.Echo (strPause)
z = WScript.StdIn.Read(1)
End Sub
First, you need to check the port 9042 whether this open or not if open then check below things like rpc_address and listen_address. you should set the server own IP address instead 0.0.0.0 or 127.0.0.1.
If all okay then please run below command to connect cqlsh.
cqlsh IP address 9042
If you enable authentication and authorization you have to put user/pass with this command.
in Firefox 39 I've found that setting a border to the select element will render the arrow as (2). No border set, will render the arrow as (1). I think it's a bug.
You can do the following. It also avoids buttons overlapping.

I tried changing value="true"
to ng-value="true"
, and it seems to work.
<input type="radio" name="response2" data-ng-model="choice.isUserAnswer" ng-value="true" />
Also, to get both inputs to work in your example, you'd have to give different name to each input -- e.g. response
should become response1
and response2
.

Ok, I feel a bit stupid here... what's the reason not to just do it with something like
[(a+1,b) for (a,b) in enumerate(r)]
? If you won't function, no problem either:
>>> r = range(2000, 2005)
>>> [(a+1,b) for (a,b) in enumerate(r)]
[(1, 2000), (2, 2001), (3, 2002), (4, 2003), (5, 2004)]
>>> enumerate1 = lambda r:((a+1,b) for (a,b) in enumerate(r))
>>> list(enumerate1(range(2000,2005))) # note - generator just like original enumerate()
[(1, 2000), (2, 2001), (3, 2002), (4, 2003), (5, 2004)]
while True:
...
means infinite loop.
The while statement is often used of a finite loop. But using the constant 'True' guarantees the repetition of the while statement without the need to control the loop (setting a boolean value inside the iteration for example), unless you want to break it.
In fact
True == (1 == 1)

Here's an example of how to validate a int and a String that you pass from the Java Controller to the JSP file.
MainController.java:
@RequestMapping(value="/ImportJavaToJSP")
public ModelAndView getImportJavaToJSP() {
ModelAndView model2= new ModelAndView("importJavaToJSPExamples");
int someNumberValue=6;
String someStringValue="abcdefg";
//model2.addObject("someNumber", someNumberValue);
model2.addObject("someString", someStringValue);
return model2;
}
importJavaToJSPExamples.jsp
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<p>${someNumber}</p>
<c:if test="${not empty someNumber}">
<p>someNumber is Not Empty</p>
</c:if>
<c:if test="${empty someNumber}">
<p>someNumber is Empty</p>
</c:if>
<p>${someString}</p>
<c:if test="${not empty someString}">
<p>someString is Not Empty</p>
</c:if>
<c:if test="${empty someString}">
<p>someString is Empty</p>
</c:if>
There isn't really a way to do this without the css getting a little convoluted, but here's the cleanest solution I could put together (the breakpoints in this are just for example purposes, change them to whatever breakpoints you're actually using.) The key is :nth-of-type
(or :nth-child
-- either would work in this case.)
Smallest viewport:
@media (max-width:$smallest-breakpoint) {
.row div {
background: #eee;
}
.row div:nth-of-type(2n) {
background: #fff;
}
}
Medium viewport:
@media (min-width:$smallest-breakpoint) and (max-width:$mid-breakpoint) {
.row div {
background: #eee;
}
.row div:nth-of-type(4n+1), .row div:nth-of-type(4n+2) {
background: #fff;
}
}
Largest viewport:
@media (min-width:$mid-breakpoint) and (max-width:9999px) {
.row div {
background: #eee;
}
.row div:nth-of-type(6n+4),
.row div:nth-of-type(6n+5),
.row div:nth-of-type(6n+6) {
background: #fff;
}
}
Working fiddle here
You can add a class to the parent of the red div, e.g. green-style
$('.red').parent().addClass('green-style');
then add style to the css
.green-style .red {
background:green;
}
so everytime you add red element under green-style, the background will be green
This is the fix that worked for me. There is invalid mime or bad characterset being sent with your json data causing that errror. Add the charset like this to help it from getting confused:
$.ajax({
url:url,
type:"POST",
data:data,
contentType:"application/json; charset=utf-8",
dataType:"json",
success: function(){
...
}
});

I can elaborate on the details of DLLs in Windows to help clarify those mysteries to my friends here in *NIX-land...
A DLL is like a Shared Object file. Both are images, ready to load into memory by the program loader of the respective OS. The images are accompanied by various bits of metadata to help linkers and loaders make the necessary associations and use the library of code.
Windows DLLs have an export table. The exports can be by name, or by table position (numeric). The latter method is considered "old school" and is much more fragile -- rebuilding the DLL and changing the position of a function in the table will end in disaster, whereas there is no real issue if linking of entry points is by name. So, forget that as an issue, but just be aware it's there if you work with "dinosaur" code such as 3rd-party vendor libs.
Windows DLLs are built by compiling and linking, just as you would for an EXE (executable application), but the DLL is meant to not stand alone, just like an SO is meant to be used by an application, either via dynamic loading, or by link-time binding (the reference to the SO is embedded in the application binary's metadata, and the OS program loader will auto-load the referenced SO's). DLLs can reference other DLLs, just as SOs can reference other SOs.
In Windows, DLLs will make available only specific entry points. These are called "exports". The developer can either use a special compiler keyword to make a symbol an externally-visible (to other linkers and the dynamic loader), or the exports can be listed in a module-definition file which is used at link time when the DLL itself is being created. The modern practice is to decorate the function definition with the keyword to export the symbol name. It is also possible to create header files with keywords which will declare that symbol as one to be imported from a DLL outside the current compilation unit. Look up the keywords __declspec(dllexport) and __declspec(dllimport) for more information.
One of the interesting features of DLLs is that they can declare a standard "upon load/unload" handler function. Whenever the DLL is loaded or unloaded, the DLL can perform some initialization or cleanup, as the case may be. This maps nicely into having a DLL as an object-oriented resource manager, such as a device driver or shared object interface.
When a developer wants to use an already-built DLL, she must either reference an "export library" (*.LIB) created by the DLL developer when she created the DLL, or she must explicitly load the DLL at run time and request the entry point address by name via the LoadLibrary() and GetProcAddress() mechanisms. Most of the time, linking against a LIB file (which simply contains the linker metadata for the DLL's exported entry points) is the way DLLs get used. Dynamic loading is reserved typically for implementing "polymorphism" or "runtime configurability" in program behaviors (accessing add-ons or later-defined functionality, aka "plugins").
The Windows way of doing things can cause some confusion at times; the system uses the .LIB extension to refer to both normal static libraries (archives, like POSIX *.a files) and to the "export stub" libraries needed to bind an application to a DLL at link time. So, one should always look to see if a *.LIB file has a same-named *.DLL file; if not, chances are good that *.LIB file is a static library archive, and not export binding metadata for a DLL.
Do this recursively:
public String replaceSpace(String s){
if (s.length() < 2) {
if(s.equals(" "))
return "+";
else
return s;
}
if (s.charAt(0) == ' ')
return "+" + replaceSpace(s.substring(1));
else
return s.substring(0, 1) + replaceSpace(s.substring(1));
}
In C++, a constructor with only one required parameter is considered an implicit conversion function. It converts the parameter type to the class type. Whether this is a good thing or not depends on the semantics of the constructor.
For example, if you have a string class with constructor String(const char* s)
, that's probably exactly what you want. You can pass a const char*
to a function expecting a String
, and the compiler will automatically construct a temporary String
object for you.
On the other hand, if you have a buffer class whose constructor Buffer(int size)
takes the size of the buffer in bytes, you probably don't want the compiler to quietly turn int
s into Buffer
s. To prevent that, you declare the constructor with the explicit
keyword:
class Buffer { explicit Buffer(int size); ... }
That way,
void useBuffer(Buffer& buf);
useBuffer(4);
becomes a compile-time error. If you want to pass a temporary Buffer
object, you have to do so explicitly:
useBuffer(Buffer(4));
In summary, if your single-parameter constructor converts the parameter into an object of your class, you probably don't want to use the explicit
keyword. But if you have a constructor that simply happens to take a single parameter, you should declare it as explicit
to prevent the compiler from surprising you with unexpected conversions.
Open the mysql terminal:
el@apollo:~$ mysql -u root -pthepassword yourdb
mysql>
Drop the function if it already exists
mysql> drop function if exists myfunc;
Query OK, 0 rows affected, 1 warning (0.00 sec)
Create the function
mysql> create function hello(id INT)
-> returns CHAR(50)
-> return 'foobar';
Query OK, 0 rows affected (0.01 sec)
Create a simple table to test it out with
mysql> create table yar (id INT);
Query OK, 0 rows affected (0.07 sec)
Insert three values into the table yar
mysql> insert into yar values(5), (7), (9);
Query OK, 3 rows affected (0.04 sec)
Records: 3 Duplicates: 0 Warnings: 0
Select all the values from yar, run our function hello each time:
mysql> select id, hello(5) from yar;
+------+----------+
| id | hello(5) |
+------+----------+
| 5 | foobar |
| 7 | foobar |
| 9 | foobar |
+------+----------+
3 rows in set (0.01 sec)
Verbalize and internalize what just happened:
You created a function called hello which takes one parameter. The parameter is ignored and returns a CHAR(50)
containing the value 'foobar'. You created a table called yar and added three rows to it. The select statement runs the function hello(5)
for each row returned by yar.

Using an in
can have a performance impact. Joining two subqueries will not have the same performance impact and can be accomplished like this:
SELECT *
FROM (SELECT msisdn
,callid
,Change_color
,play_file_name
,date_played
FROM insert_log
WHERE play_file_name NOT IN('Prompt1','Conclusion_Prompt_1','silent')
ORDER BY callid ASC) t1
JOIN (SELECT MAX(date_played) AS date_played
FROM insert_log GROUP BY callid) t2
ON t1.date_played = t2.date_played
I propose following solution:
DataView view = new DataView(myDataTable);
view.RowFilter = "RowNo = 1";
DataTable results = view.ToTable(true);
Looking at the DataView Documentation, the first thing we can see is this:
Represents a databindable, customized view of a DataTable for sorting, filtering, searching, editing, and navigation.
What I am getting from this is that DataTable is meant to only store data and DataView is there enable us to "query" against the DataTable.
Here is how this works in this particular case:
You try to implement the SQL Statement
SELECT *
FROM myDataTable
WHERE RowNo = 1
in "DataTable language". In C# we would read it like this:
FROM myDataTable
WHERE RowNo = 1
SELECT *
which looks in C# like this:
DataView view = new DataView(myDataTable); //FROM myDataTable
view.RowFilter = "RowNo = 1"; //WHERE RowNo = 1
DataTable results = view.ToTable(true); //SELECT *
Although I am very late to this but after seeing some legitimate questions for those who wanted to use INSERT-SELECT
query with GROUP BY
clause, I came up with the work around for this.
Taking further the answer of Marcus Adams and accounting GROUP BY
in it, this is how I would solve the problem by using Subqueries in the FROM Clause

You can easily use xml

def iter_docs(author):
author_attr = author.attrib
for doc in author.iter('document'):
doc_dict = author_attr.copy()
doc_dict.update(doc.attrib)
doc_dict['data'] = doc.text
yield doc_dict
xml_data = io.StringIO(u'''\

etree = ET.parse(xml_data) #create an ElementTree object
doc_df = pd.DataFrame(list(iter_docs(etree.getroot())))
If there are multiple authors in your original document or the root of your XML is not an author
, then I would add the following generator:
def iter_author(etree):
for author in etree.iter('author'):
for row in iter_docs(author):
yield row
and change doc_df = pd.DataFrame(list(iter_docs(etree.getroot())))
to doc_df = pd.DataFrame(list(iter_author(etree)))
Have a look at the ElementTree
tutorial provided in the xml
library documentation.
If using jQuery Mobile you will experience the new window when using the data-ajax='false' attribute. In fact, this will happen whenever ajaxEnabled is turned off, being by and external link, by a $.mobile.ajaxEnabled setting or by having a target='' attribute.
You may fix it using this:
$("a[data-ajax='false']").live("click", function(event){
if (this.href) {
event.preventDefault();
location.href=this.href;
return false;
}
});
(Thanks to Richard Poole for the live() method - wasn't working with bind())
If you've turned ajaxEnabled off globally, you will need to drop the [data-ajax='false'].
This took me rather long to figure out as I was expecting it to be a jQuery Mobile specific problem where in fact it was the Ajax linking that actually prohibited the new window.
Recursively find all controls matching the specified predicate (do not include root Control):
public static IEnumerable<Control> FindControlsRecursive(this Control control, Func<Control, bool> predicate)
{
var results = new List<Control>();
foreach (Control child in control.Controls)
{
if (predicate(child))
{
results.Add(child);
}
results.AddRange(child.FindControlsRecursive(predicate));
}
return results;
}
Usage:
myControl.FindControlsRecursive(c => c.ID == "findThisID");

You need to configure the security group as stated by cyraxjoe. Along with that you also need to open System port. Steps to open port in windows :-
Friends, to keep everything clean you can use de commands:
if your are using server, there's "public network IP" and "internal network IP". Use the "internal network IP" in your file /etc/hosts and "public network IP" in your code. if you use "public network IP" in your file /etc/hosts then you will get this error.
Here's a way to do it using your own variable and keeping it concise:
List<String> list = Arrays.asList("zero", "one", "two");
int i = 0;
for (Iterator<String> it = list.iterator(); it.hasNext(); i++) {
String s = it.next();
System.out.println(i + ": " + s);
}
Output (you guessed it):
0: zero
1: one
2: two
The advantage is that you don't increment your index within the loop (although you need to be careful to only call Iterator#next once per loop - just do it at the top).

You want to use DATEADD, using a negative duration. e.g.
DATEADD(minute, -15, '2000-01-01 08:30:00')
The standard solution didn't work for me, when changing the type from TEXT to LONGTEXT.
I had to it like this:
public function up()
{
DB::statement('ALTER TABLE mytable MODIFY mycolumn LONGTEXT;');
}
public function down()
{
DB::statement('ALTER TABLE mytable MODIFY mycolumn TEXT;');
}
This could be a Doctrine issue. More information here.
Another way to do it is to use the string() method, and set the value to the text type max length:
Schema::table('mytable', function ($table) {
// Will set the type to LONGTEXT.
$table->string('mycolumn', 4294967295)->change();
});

First, all collections in .NET implement IEnumerable.
Second, a lot of the collections are duplicates because generics were added in version 2.0 of the framework.
So, although the generic collections likely add features, for the most part:
Arrays are a fixed size collection that you can change the value stored at a given index.
SortedDictionary is an IDictionary that is sorted based on the keys. SortedList is an IDictionary that is sorted based on a required IComparer.
So, the IDictionary implementations (those supporting KeyValuePairs) are: * Hashtable * Dictionary * SortedList * SortedDictionary
Another collection that was added in .NET 3.5 is the Hashset. It is a collection that supports set operations.
Also, the LinkedList is a standard linked-list implementation (the List is an array-list for faster retrieval).
There is no standard C (or C++) way to enumerate files in a directory.
Under Windows you can use the FindFirstFile/FindNextFile functions to enumerate all entries in a directory. Under Linux/OSX use the opendir/readdir/closedir functions.
You could have one abstract base class that implements both IFirst and ISecond, and then inherit from just that base.

execve()
replaces the current executable image with another one loaded from an executable file.fork()
creates a child process.vfork()
is a historical optimized version of fork()
, meant to be used when execve()
is called directly after fork()
. It turned out to work well in non-MMU systems (where fork()
cannot work in an efficient manner) and when fork()
ing processes with a huge memory footprint to run some small program (think Java's Runtime.exec()
). POSIX has standardized the posix_spawn()
to replace these latter two more modern uses of vfork()
.posix_spawn()
does the equivalent of a fork()/execve()
, and also allows some fd juggling in between. It's supposed to replace fork()/execve()
, mainly for non-MMU platforms.pthread_create()
creates a new thread.clone()
is a Linux-specific call, which can be used to implement anything from fork()
to pthread_create()
. It gives a lot of control. Inspired on rfork()
.rfork()
is a Plan-9 specific call. It's supposed to be a generic call, allowing several degrees of sharing, between full processes and threads.Your server process has received a SIGPIPE
writing to a socket. This usually happens when you write to a socket fully closed on the other (client) side. This might be happening when a client program doesn't wait till all the data from the server is received and simply closes a socket (using close
function).
In a C program you would normally try setting to ignore SIGPIPE
signal or setting a dummy signal handler for it. In this case a simple error will be returned when writing to a closed socket. In your case a python seems to throw an exception that can be handled as a premature disconnect of the client.
>>> tup = (1, 2, 3)
>>> print "Here it is: %s" % (tup,)
Here it is: (1, 2, 3)
>>>
Note that (tup,)
is a tuple containing a tuple. The outer tuple is the argument to the % operator. The inner tuple is its content, which is actually printed.
(tup)
is an expression in brackets, which when evaluated results in tup
.
(tup,)
with the trailing comma is a tuple, which contains tup
as is only member.
You can use .ajaxStop()
or .ajaxComplete()
.ajaxComplete()
fires after completion of each AJAX request on your page.
$( document ).ajaxComplete(function() {
yourFunction();
});
.ajaxStop()
fires after completion of all AJAX requests on your page.
$( document ).ajaxStop(function() {
yourFunction();
});
json_decode()
will return an object or array if second value it's true:
$json = '{"countryId":"84","productId":"1","status":"0","opId":"134"}';
$json = json_decode($json, true);
echo $json['countryId'];
echo $json['productId'];
echo $json['status'];
echo $json['opId'];
Use the substring method of the String class :
String removeCurrency=amount.getText().toString().substring(3);
Editor's note: disabling SSL verification has security implications. Without verification of the authenticity of SSL/HTTPS connections, a malicious attacker can impersonate a trusted endpoint such as Gmail, and you'll be vulnerable to a Man-in-the-Middle Attack.
Be sure you fully understand the security issues before using this as a solution.
You can add below code in /config/mail.php ( tested and worked on laravel 5.1, 5.2, 5.4 )
'stream' => [
'ssl' => [
'allow_self_signed' => true,
'verify_peer' => false,
'verify_peer_name' => false,
],
],
You can also use CURRENT_TIMESTAMP
for this.
According to BOL CURRENT_TIMESTAMP
is the ANSI SQL
euivalent to GETDATE()
DECLARE @LastChangeDate AS DATE;
SET @LastChangeDate = CURRENT_TIMESTAMP;
The "0x" counts towards the eight character count. You need "%#010x"
.
Note that #
does not append the 0x to 0 - the result will be 0000000000
- so you probably actually should just use "0x%08x"
anyway.
You can use the lower
function:
Guide.where("lower(title)='attack'")
As a comment: Work on your question. The title isn't terribly informative, and you drop a big chunk of code at the end that is irrelevant to your question.
You don't need a function for it - simply use the bracket notation:
var side = columns['right'];
This is equal to dot notation, var side = columns.right;
, except the fact that right
could also come from a variable, function return value, etc., when using bracket notation.
If you NEED a function for it, here it is:
function read_prop(obj, prop) {
return obj[prop];
}
To answer some of the comments below that aren't directly related to the original question, nested objects can be referenced through multiple brackets. If you have a nested object like so:
var foo = { a: 1, b: 2, c: {x: 999, y:998, z: 997}};
you can access property x
of c
as follows:
var cx = foo['c']['x']
If a property is undefined, an attempt to reference it will return undefined
(not null
or false
):
foo['c']['q'] === null
// returns false
foo['c']['q'] === false
// returns false
foo['c']['q'] === undefined
// returns true
Right click on folder.

Click Security Tab. You will see something like this:
Check/uncheck whatever access you need to grant to the account
Click Apply button and then OK.
If you have SELinux running, you might have to grant httpd permission to read from /home dir using:

I had a similar problem. I had saved some xml in a file and when reading it into a DOM document, it failed due to special character. Then I used the following code to fix it:
String enco = new String(Files.readAllBytes(Paths.get(listPayloadPath+"/Payload.xml")), StandardCharsets.UTF_8);
Document doc = builder.parse(new ByteArrayInputStream(enco.getBytes(StandardCharsets.UTF_8)));
Let me know if it works for you.
Use chown
to change ownership and chmod
to change rights.
use the -R
option to apply the rights for all files inside of a directory too.
Note that both these commands just work for directories too. The -R
option makes them also change the permissions for all files and directories inside of the directory.
For example
sudo chown -R username:group directory
will change ownership (both user and group) of all files and directories inside of directory and directory itself.
sudo chown username:group directory
will only change the permission of the folder directory but will leave the files and folders inside the directory alone.
you need to use sudo to change the ownership from root to yourself.
Edit:
Note that if you use chown user: file
(Note the left-out group), it will use the default group for that user.
Also You can change the group ownership of a file or directory with the command:
chgrp group_name file/directory_name
You must be a member of the group to which you are changing ownership to.
You can find group of file as follows
# ls -l file
-rw-r--r-- 1 root family 0 2012-05-22 20:03 file
# chown sujit:friends file
User 500 is just a normal user. Typically user 500 was the first user on the system, recent changes (to /etc/login.defs) has altered the minimum user id to 1000 in many distributions, so typically 1000 is now the first (non root) user.
What you may be seeing is a system which has been upgraded from the old state to the new state and still has some processes knocking about on uid 500. You can likely change it by first checking if your distro should indeed now use 1000, and if so alter the login.defs file yourself, the renumber the user account in /etc/passwd and chown/chgrp all their files, usually in /home/, then reboot.
But in answer to your question, no, you should not really be worried about this in all likelihood. It'll be showing as "500" instead of a username because o user in /etc/passwd has a uid set of 500, that's all.
Also you can show your current numbers using id i'm willing to bet it comes back as 1000 for you.
This might be an alternative solution. Paste the following code into the new module:
Public Function ModDate()
ModDate =
Format(FileDateTime(ThisWorkbook.FullName), "m/d/yy h:n ampm")
End Function
Before saving your module, make sure to save your Excel file as Excel Macro-Enabled Workbook.
Paste the following code into the cell where you want to display the last modification time:
=ModDate()
I'd also like to recommend an alternative to Excel allowing you to add creation and last modification time easily. Feel free to check on RowShare and this article I wrote: https://www.rowshare.com/blog/en/2018/01/10/Displaying-Last-Modification-Time-in-Excel
You can create you own exception by inheriting from java.lang.Exception
Here is an example that can help you do that.
They are names for the same standard from two different industries with different naming methods, the guys who make & sell movies and the guys who transfer the movies over the internet. Since 2003: "MPEG 4 Part 10" = "H.264" = "AVC". Before that the relationship was a little looser in that they are not equal but an "MPEG 4 Part 2" decoder can render a stream that's "H.263". The Next standard is "MPEG H Part 2" = "H.265" = "HEVC"
For windows - just go to Mongodb folder (ex : C:\ProgramFiles\MongoDB\Server\3.4\bin) and open cmd in the folder and type "mongod.exe --dbpath c:\data\db"
if c:\data\db folder doesn't exist then create it by yourself and run above command again.
All should work fine by now.))
One more thing that could cause this is having incorrect version
of the <parent>
project.
In my case it was pointing to a non-existing project and for some reason IntelliJ downgraded version in settings to 1.5 and later when I fixed it, it was still interpreting target code version as 5 (despite setting it to 11).
I know I'm updating a quite old post, and I tried using automodinit
, but found out it's setup process is broken for python3. So, based on Luca's answer, I came up with a simpler answer - which might not work with .zip - to this issue, so I figured I should share it here:
within the __init__.py
module from yourpackage
:
#!/usr/bin/env python
import os, pkgutil
__all__ = list(module for _, module, _ in pkgutil.iter_modules([os.path.dirname(__file__)]))
and within another package below yourpackage
:
from yourpackage import *
Then you'll have all the modules that are placed within the package loaded, and if you write a new module, it'll be automagically imported as well. Of course, use that kind of things with care, with great powers comes great responsibilities.
I was also facing the same problem for twitter-bootstrap.
As eternicode/bootstrap-datepicker is incompatible with jQuery UI.
But twitter-bootstrap is working fine for vitalets/bootstrap-datepicker even with jQuery UI.
Use NSLock in Swift4:
let lock = NSLock()
lock.lock()
if isRunning == true {
print("Service IS running ==> please wait")
return
} else {
print("Service not running")
}
isRunning = true
lock.unlock()
Warning The NSLock class uses POSIX threads to implement its locking behavior. When sending an unlock message to an NSLock object, you must be sure that message is sent from the same thread that sent the initial lock message. Unlocking a lock from a different thread can result in undefined behavior.
Make sure of that you have installed ruby with --disable-binary option, if not, uninstall it and reinstall it with the option.

Some of the answers above allude to the problem but don't clearly spell out the steps to correct it.
Here is my attempt at after it has become super frustrating which seems to have worked for me so far :
The problem is caused because there is duplicate certificates in your Apple Developer portal or potentially in your machine. I haven't had any negative consequences from doing this and its worked so far.
Close Xcode!
You have to remove the existing certs from your developer account visit : https://developer.apple.com/account/ios/certificate/development/ and select development account ( there should be multiple certs) I revoked each one by clicking on them and selecting revoke.
2.remove certs from your keychain on your Mac
Lastly regenerate your certs in XCode and rebooot
Quite amazing how all answers talk about IIS, as if that were the only web server that mattered. Even back in 2010 when the question was asked, Apache had between 60% and 70% of the market share. Anyway,

.Here are the POST body sizes for some of the more popular HTTP servers:
I've just came across the same problem and found the chrome extension Open IE.
That's the only one what works for me (Chrome V46 & V52). The only disadvantefge is, that you need to install an additional program, means you need admin rights.
IF you want more data in you confusion matrix, including "totals column" and "totals line", and percents (%) in each cell, like matlab default (see image below)
including the Heatmap and other options...
You should have fun with the module above, shared in the github ; )

This module can do your task easily and produces the output above with a lot of params to customize your CM:
Based on the syntax I'm assuming that it is some language which is descendant of C. As per what I have seen, length
is used for simple collection items like arrays and in most cases it is a property.
size()
is a function and is used for dynamic collection objects. However for all the purposes of using, you wont find any differences in outcome using either of them. In most implementations, size simply returns length property.
Switch to your local branch
> git checkout configUpdate
Merge remote master to your branch
> git rebase master configUpdate
In case you have any conflicts, correct them and for each conflicted file do the command
> git add [path_to_file/conflicted_file] (e.g. git add app/assets/javascripts/test.js)
Continue rebase
> git rebase --continue
Because I often find myself working with multiple environment variables, I find it useful to keep them in a separate .env
file (make sure to ignore this from your source control). Then (in Linux) prepend export $(cat .env | xargs) &&
in your script command before starting your app.
Example .env
file:
VAR_A=Hello World
VAR_B=format the .env file like this with new vars separated by a line break
Example index.js
:
console.log('Test', process.env.VAR_A, process.env.VAR_B);
Example package.json
:
{
...
"scripts": {
"start": "node index.js",
"env-linux": "export $(cat .env | xargs) && env",
"start-linux": "export $(cat .env | xargs) && npm start",
"env-windows": "(for /F \"tokens=*\" %i in (.env) do set %i)",
"start-windows": "(for /F \"tokens=*\" %i in (.env) do set %i) && npm start",
}
...
}
Unfortunately I can't seem to set the environment variables by calling a script from a script -- like "start-windows": "npm run env-windows && npm start"
-- so there is some redundancy in the scripts.
For a test you can see the env variables by running npm run env-linux
or npm run env-windows
, and test that they make it into your app by running npm run start-linux
or npm run start-windows
.
Following are few libraries to create PDF with Java:
I have used iText for genarating PDF's with a little bit of pain in the past.
Or you can try using FOP: FOP is an XSL formatter written in Java. It is used in conjunction with an XSLT transformation engine to format XML documents into PDF.
It helped me to convert the result of simplexml_load_file($file) into a JSON Structure and decode it back:
$xml = simplexml_load_file("$token.xml");
$json = json_encode($xml);
$xml_fixed = json_decode($json);
$try1 = $xml->structure->{"@attributes"}['value'];
print_r($try1);
>> result: SimpleXMLElement Object
(
)
$try2 = $xml_fixed->structure->{"@attributes"}['value'];
print_r($try2);
>> result: stdClass Object
(
[key] => value
)
There are few modes to open file (read, write etc..)
If you want to read from file you should type file = open("File.txt","r")
, if write than file = open("File.txt","w")
. You need to give the right permission regarding your usage.
more modes:
Just add this after jQuery loads and before your code.
$(window).ajaxComplete(function () {console.log('Ajax Complete'); });
$(window).ajaxError(function (data, textStatus, jqXHR) {console.log('Ajax Error');
console.log('data: ' + data);
console.log('textStatus: ' + textStatus);
console.log('jqXHR: ' + jqXHR); });
$(window).ajaxSend(function () {console.log('Ajax Send'); });
$(window).ajaxStart(function () {console.log('Ajax Start'); });
$(window).ajaxStop(function () {console.log('Ajax Stop'); });
$(window).ajaxSuccess(function () {console.log('Ajax Success'); });

Based on https://stackoverflow.com/a/48195124/16777 but fixed to actually work in zero-results case.
The c++ inline
keyword is misleading, it doesn't mean "inline this function". If a function is defined as inline, it simply means that it can be defined multiple times as long as all definitions are equal. It's perfectly legal for a function marked inline
to be a real function that is called instead of getting code inlined at the point where it's called.
Defining a function in a header file is needed for templates, since e.g. a templated class isn't really a class, it's a template for a class which you can make multiple variations of. In order for the compiler to be able to e.g. make a Foo<int>::bar()
function when you use the Foo template to create a Foo class, the actual definition of Foo<T>::bar()
must be visible.
Don't scroll the IFrame page or its content, scroll the parent page. If you control the IFrame content, you can use the iframe-resizer library to turn the iframe element itself into a proper block level element, with a natural/correct/native height. Also, don't attempt to position (fixed, absolute) your iframe in the parent page, or present an iframe in a modal window, especially if it has form elements.
I also suspect that iOS Safari has a non-standards behavior that expands your iframe's height to its natural height, much like the iframe-resizer library will do for desktop browsers, which seem to render responsive iframe content at height 0px or 150px or some other not useful default. If you need to contrain width, try a max-width style inside the iframe.
The mysql_upgrade worked for me as well:
# mysql_upgrade -u root -p --force
# systemctl restart mysqld

If nothing else seems to work, double-check the path in git config core.worktree
. If that path doesn't point to your working directory, you may need to update it.
The way I got this error was that I created a Git repository on a network drive. It worked fine on one computer but returned this error on another. It turned out that I had the drive mapped to a Windows drive letter on the computer where I created it, but not on the other computer, and Git saved the path to the work tree as the mapped path and not the UNC path.
I have not used Sequelize, but after reading its documentation, it's obvious that you are instantiating a new object, that's why Sequelize inserts a new record into the db.
First you need to search for that record, fetch it and only after that change its properties and update it, for example:
Project.find({ where: { title: 'aProject' } })
.on('success', function (project) {
// Check if record exists in db
if (project) {
project.update({
title: 'a very different title now'
})
.success(function () {})
}
})
You can do this using the new React ref api.
function ChildComponent({ childRef }) {
return <div ref={childRef} />;
}
class Parent extends React.Component {
myRef = React.createRef();
get doSomethingWithChildRef() {
console.log(this.myRef); // Will access child DOM node.
}
render() {
return <ChildComponent childRef={this.myRef} />;
}
}
One contending technology you've omitted is Server-Sent Events / Event Source. What are Long-Polling, Websockets, Server-Sent Events (SSE) and Comet? has a good discussion of all of these. Keep in mind that some of these are easier than others to integrate with on the server side.
