To keep this simple, I just changed the directory from which I was importing the data to a local folder on the server.
I had the file located on a shared folder, I just copied my files to "c:\TEMP\Reports" on my server (updated the query to BULK INSERT from the new folder). The Agent task completed successfully :)
Finally after a long time I'm able to BULK Insert automatically via agent job.
Best regards.
It's probably worth noting that IE won't cache css files called by other css files using the @import method. So, for example, if your html page links to "master.css" which pulls in "reset.css" via @import, then reset.css will not be cached by IE.
This error occurs when you're trying to target an element that is wrapped in a condition.
So, here if I use ngIf in place of [hidden], it will give me TypeError: Cannot read property 'nativeElement' of undefined
So use [hidden], class.show or class.hide in place of *ngIf.

One solution would be to divide your table into 20 columns of 5% width each, then use colspan on each real column to get the desired width, like this:
<html>_x000D_
<body bgcolor="#14B3D9">_x000D_
<table width="100%" border="1" bgcolor="#ffffff">_x000D_
<colgroup>_x000D_
<col width="5%"><col width="5%">_x000D_
<col width="5%"><col width="5%">_x000D_
<col width="5%"><col width="5%">_x000D_
<col width="5%"><col width="5%">_x000D_
<col width="5%"><col width="5%">_x000D_

It appears the default setting for Adobe Reader X is for the toolbars not to be shown by default unless they are explicitly turned on by the user. And even when I turn them back on during a session, they don't show up automatically next time. As such, I suspect you have a preference set contrary to the default.
The state you desire, with the top and left toolbars not shown, is called "Read Mode". If you right-click on the document itself, and then click "Page Display Preferences" in the context menu that is shown, you'll be presented with the Adobe Reader Preferences dialog. (This is the same dialog you can access by opening the Adobe Reader application, and selecting "Preferences" from the "Edit" menu.) In the list shown in the left-hand column of the Preferences dialog, select "Internet". Finally, on the right, ensure that you have the "Display in Read Mode by default" box checked:
You can also turn off the toolbars temporarily by clicking the button at the right of the top toolbar that depicts arrows pointing to opposing corners:
Finally, if you have "Display in Read Mode by default" turned off, but want to instruct the page you're loading not to display the toolbars (i.e., override the user's current preferences), you can append the following to the URL:
#toolbar=0&navpanes=0
So, for example, the following code will disable both the top toolbar (called "toolbar") and the left-hand toolbar (called "navpane"). However, if the user knows the keyboard combination (F8, and perhaps other methods as well), they will still be able to turn them back on.
string url = @"http://www.domain.com/file.pdf#toolbar=0&navpanes=0";
this._WebBrowser.Navigate(url);
You can read more about the parameters that are available for customizing the way PDF files open here on Adobe's developer website.
Use numpy.concatenate(list1 , list2)
or numpy.append()
Look into the thread at Append a NumPy array to a NumPy array.
One significant difference between INNER JOIN and NATURAL JOIN is the number of columns returned.
Consider:
TableA TableB
+------------+----------+ +--------------------+
|Column1 | Column2 | |Column1 | Column3 |
+-----------------------+ +--------------------+
| 1 | 2 | | 1 | 3 |
+------------+----------+ +---------+----------+
The INNER JOIN
of TableA and TableB on Column1 will return
SELECT * FROM TableA AS a INNER JOIN TableB AS b USING (Column1);
SELECT * FROM TableA AS a INNER JOIN TableB AS b ON a.Column1 = b.Column1;
+------------+-----------+---------------------+
| a.Column1 | a.Column2 | b.Column1| b.Column3|
+------------------------+---------------------+
| 1 | 2 | 1 | 3 |
+------------+-----------+----------+----------+
The NATURAL JOIN
of TableA and TableB on Column1 will return:
SELECT * FROM TableA NATURAL JOIN TableB
+------------+----------+----------+
|Column1 | Column2 | Column3 |
+-----------------------+----------+
| 1 | 2 | 3 |
+------------+----------+----------+
The repeated column is avoided.
(AFAICT from the standard grammar, you can't specify the joining columns in a natural join; the join is strictly name-based. See also Wikipedia.)
(There's a cheat in the inner join output; the a.
and b.
parts would not be in the column names; you'd just have column1
, column2
, column1
, column3
as the headings.)
I had the same problem, but I didnt find export command in line 70 in gradle file for the latest version 2.13, but I understand a silly mistake there, that is following,
If you don't find line 70 with export command in gradle file in your gradle folder/bin/ , then check your ~/.bashrc, if you find export JAVA_HOME==/usr/lib/jvm/java-7-openjdk-amd64/bin/java
, then remove /bin/java
from this line, like JAVA_HOME==/usr/lib/jvm/java-7-openjdk-amd64
, and it in path>>> instead of this export PATH=$PATH:$HOME/bin:JAVA_HOME/
, it will be export PATH=$PATH:$HOME/bin:JAVA_HOME/bin/java
. Then run source ~/.bashrc
.
The reason is, if you check your gradle file, you will find in line 70 (if there's no export command) or in line 75,
JAVACMD="$JAVA_HOME/bin/java" fi if [ ! -x "$JAVACMD" ] ; then die "ERROR: JAVA_HOME is set to an invalid directory: $JAVA_HOME
That means
/bin/java
is already there, so it needs to be substracted fromJAVA_HOME
path.
That happened in my case.
Java infers automatically the type of the elements in case
, so the labels must be unqualified.
int i;
switch(i) {
case 5: // <- integer is expected
}
MyEnum e;
switch (e) {
case VALUE_A: // <- an element of the enumeration is expected
}
Just a precision to Ellis Whitehead's answer. $locationProvider.html5Mode(true);
won't work with new version of angularjs without specifying the base URL for the application with a <base href="">
tag or setting the parameter requireBase
to false
If you configure $location to use html5Mode (history.pushState), you need to specify the base URL for the application with a tag or configure $locationProvider to not require a base tag by passing a definition object with requireBase:false to $locationProvider.html5Mode():
$locationProvider.html5Mode({
enabled: true,
requireBase: false
});
I think the regex / string parsing solutions are great, but for this particular context, it seems like it would make sense just to use java's url parser:
https://docs.oracle.com/javase/tutorial/networking/urls/urlInfo.html
Taken from that page:
import java.net.*;
import java.io.*;
public class ParseURL {
public static void main(String[] args) throws Exception {
URL aURL = new URL("http://example.com:80/docs/books/tutorial"
+ "/index.html?name=networking#DOWNLOADING");
System.out.println("protocol = " + aURL.getProtocol());
System.out.println("authority = " + aURL.getAuthority());
System.out.println("host = " + aURL.getHost());
System.out.println("port = " + aURL.getPort());
System.out.println("path = " + aURL.getPath());
System.out.println("query = " + aURL.getQuery());
System.out.println("filename = " + aURL.getFile());
System.out.println("ref = " + aURL.getRef());
}
}
yields the following:
protocol = http
authority = example.com:80
host = example.com
port = 80
path = /docs/books/tutorial/index.html
query = name=networking
filename = /docs/books/tutorial/index.html?name=networking
ref = DOWNLOADING
VM Player runs a virtual instance, but can't create the vm. [Edit: Now it can.] Workstation allows for the creation and administration of virtual machines. If you have a second machine, you can create the vm on one and run it with the player the other machine. I bought Workstation and I use it setup testing vms that the player runs. Hope this explains it for you.
Edit: According to the FAQ:
VMware Workstation is much more advanced and comes with powerful features including snapshots, cloning, remote connections to vSphere, sharing VMs, advanced Virtual Machines settings and much more. Workstation is designed to be used by technical professionals such as developers, quality assurance engineers, systems engineers, IT administrators, technical support representatives, trainers, etc.

Ok, Denizens. So I have accepted the command line length limits as gospel for quite some time. So, what to do with one's assumptions? Naturally- check them.
I have a Fedora 22 machine at my disposal (meaning: Linux with bash4). I have created a directory with 500,000 inodes (files) in it each of 18 characters long. The command line length is 9,500,000 characters. Created thus:
seq 1 500000 | while read digit; do
touch $(printf "abigfilename%06d\n" $digit);
done
And we note:
$ getconf ARG_MAX
2097152
Note however I can do this:
$ echo * > /dev/null
But this fails:
$ /bin/echo * > /dev/null
bash: /bin/echo: Argument list too long
I can run a for loop:
$ for f in *; do :; done
which is another shell builtin.
Careful reading of the documentation for ARG_MAX
states, Maximum length of argument to the exec functions. This means: Without calling exec
, there is no ARG_MAX
limitation. So it would explain why shell builtins are not restricted by ARG_MAX
.
And indeed, I can ls
my directory if my argument list is 109948 files long, or about 2,089,000 characters (give or take). Once I add one more 18-character filename file, though, then I get an Argument list too long error. So ARG_MAX
is working as advertised: the exec is failing with more than ARG_MAX
characters on the argument list- including, it should be noted, the environment data.
ActiveWorkbook.FullName would be better I think, in case you have the VBA Macro stored in another Excel Workbook, but you want to get the details of the Excel you are editing, not where the Macro resides.
If they reside in the same file, then it does not matter, but if they are in different files, and you want the file where the Data is rather than where the Macro is, then ActiveWorkbook is the one to go for, because it deals with both scenarios.
If this is really slow, I suspect you're dealing with a large archive file. It's going to uncompress it once to extract the file list, and then uncompress it N times--where N is the number of files in the archive--for the grep. In addition to all the uncompressing, it's going to have to scan a fair bit into the archive each time to extract each file. One of tar
's biggest drawbacks is that there is no table of contents at the beginning. There's no efficient way to get information about all the files in the archive and only read that portion of the file. It essentially has to read all of the file up to the thing you're extracting every time; it can't just jump to a filename's location right away.
The easiest thing you can do to speed this up would be to uncompress the file first (gunzip file.tar.gz
) and then work on the .tar
file. That might help enough by itself. It's still going to loop through the entire archive N times, though.
If you really want this to be efficient, your only option is to completely extract everything in the archive before processing it. Since your problem is speed, I suspect this is a giant file that you don't want to extract first, but if you can, this will speed things up a lot:
tar zxf file.tar.gz
for f in hopefullySomeSubdir/*; do
grep -l "string" $f
done
Note that grep -l
prints the name of any matching file, quits after the first match, and is silent if there's no match. That alone will speed up the grepping portion of your command, so even if you don't have the space to extract the entire archive, grep -l
will help. If the files are huge, it will help a lot.
If you have saved the excel file in the same folder as your python program (relative paths) then you just need to mention sheet number along with file name.
Example:
data = pd.read_excel("wt_vs_ht.xlsx", "Sheet2")
print(data)
x = data.Height
y = data.Weight
plt.plot(x,y,'x')
plt.show()
If you're using a version of Java prior to 8... you can use Joda Time and PeriodFormatter
. If you've really got a duration (i.e. an elapsed amount of time, with no reference to a calendar system) then you should probably be using Duration
for the most part - you can then call toPeriod
(specifying whatever PeriodType
you want to reflect whether 25 hours becomes 1 day and 1 hour or not, etc) to get a Period
which you can format.
If you're using Java 8 or later: I'd normally suggest using java.time.Duration
to represent the duration. You can then call getSeconds()
or the like to obtain an integer for standard string formatting as per bobince's answer if you need to - although you should be careful of the situation where the duration is negative, as you probably want a single negative sign in the output string. So something like:
public static String formatDuration(Duration duration) {
long seconds = duration.getSeconds();
long absSeconds = Math.abs(seconds);
String positive = String.format(
"%d:%02d:%02d",
absSeconds / 3600,
(absSeconds % 3600) / 60,
absSeconds % 60);
return seconds < 0 ? "-" + positive : positive;
}
Formatting this way is reasonably simple, if annoyingly manual. For parsing it becomes a harder matter in general... You could still use Joda Time even with Java 8 if you want to, of course.
std::copy is what you're looking for.
Set the distance from the top of the scrollable element to be the total height of the element.
const element = this.shadowRoot.getElementById('my-scrollable-div')
element.scrollTop = element.scrollHeight
@{var listItems = new List<ListItem>
{
new ListItem { Text = "Exemplo1", Value="Exemplo1" },
new ListItem { Text = "Exemplo2", Value="Exemplo2" },
new ListItem { Text = "Exemplo3", Value="Exemplo3" }
};
}
@Html.DropDownList("Exemplo",new SelectList(listItems,"Value","Text"))
Reinstall everything??? no way! just add the path to SDK tools and platform tools in your classpath from Environment Variables.
Then restart Eclipse.
other way go to Devices -> Reset adb
, or simply open the task manager and kill the adb.exe
process.
In case of Request to a REST Service:
You need to allow the CORS (cross origin sharing of resources) on the endpoint of your REST Service with Spring annotation:
@CrossOrigin(origins = "http://localhost:8080")
Very good tutorial: https://spring.io/guides/gs/rest-service-cors/
var SelecetdSteps = Context.FFTrakingSubCriticalSteps
.Where(x => x.MeetingId == meetid)
.Select(x =>
x.StepID
);
var crtiticalsteps = Context.MT_CriticalSteps.Where(x =>x.cropid==FFT.Cropid).Select(x=>new
{
StepID= x.crsid,
x.Name,
Checked=false
});
var quer = from ax in crtiticalsteps
where (!SelecetdSteps.Contains(ax.StepID))
select ax;
For this, you will need to utilise JavaScript, or rely on the somewhat supported calc()
CSS expression.
window.addEventListener("resize", function(e) {
var mapElement = document.getElementById("map");
mapElement.style.height = mapElement.offsetWidth * 1.72;
});
Or using CSS calc (see support here: http://caniuse.com/calc)
#map {
width: 100%;
height: calc(100vw * 1.72)
}
This is a late addition but I was looking for information on the scale function myself and though it might help somebody else as well.
To modify the response from Ricardo Saporta a little bit.
Scaling is not done using standard deviation, at least not in version 3.6.1 of R, I base this on "Becker, R. (2018). The new S language. CRC Press." and my own experimentation.
X.man.scaled <- X/sqrt(sum(X^2)/(length(X)-1))
X.aut.scaled <- scale(X, center = F)
The result of these rows are exactly the same, I show it without centering because of simplicity.
I would respond in a comment but did not have enough reputation.
The class AbstractMap.SimpleEntry is generic and can be useful.
And there it is... right under my nose:
From the react docs themselves: https://facebook.github.io/react/docs/reusable-components.html
// An array of a certain type
optionalArrayOf: React.PropTypes.arrayOf(React.PropTypes.number),
Tried the below program , With both the approach. 1. With clearing the arraylist obj in for loop 2. creating new New Arraylist in for loop.
List al= new ArrayList();
for(int i=0;i<100;i++)
{
//List al= new ArrayList();
for(int j=0;j<10;j++)
{
al.add(Integer.parseInt("" +j+i));
//System.out.println("Obj val " +al.get(j));
}
//System.out.println("Hashcode : " + al.hashCode());
al.clear();
}
and to my surprise. the memory allocation didnt change much.
With New Arraylist approach.
Before loop total free memory: 64,909 ::
After loop total free memory: 64,775 ::
with Clear approach,
Before loop total free memory: 64,909 :: After loop total free memory: 64,765 ::
So this says there is not much difference in using arraylist.clear from memory utilization perspective.
The Request object is the entire request sent out to some server. This object comes with a QueryString dictionary that is everything after '?' in the URL.

In node V10, you can use the flag --experimental-modules
to tell Nodejs you want to use import
. But your entry script should end with .mjs
.
Note this is still an experimental thing and should not be used in production.
// main.mjs
import utils from './utils.js'
utils.print();
// utils.js
module.exports={
print:function(){console.log('print called')}
}

For collapse, you can try CTRL + M + O and expand using CTRL + M + P. This works in VS2008.
HorizontialListView can't work when the data in the adapter is involved in another thread. Everything runs 100% on UI thread.This is a big problem in multithread. I think using HorizontialListView is not the best solution for your problem.HorzListView is a better way.You just replace your previous Gallery with HorzListView.You neednot modify the code about the adapter.Then everything goes the way you hope.See https://stackoverflow.com/a/12339708/1525777 about HorzListView.
As for me, this approach is prettier:
String.prototype.embraceWith = function(tag) {
return "<" + tag + ">" + this + "</" + tag + ">";
};
var results = [
{type:"Fiat", model:500, color:"white"},
{type:"Mercedes", model: "Benz", color:"black"},
{type:"BMV", model: "X6", color:"black"}
];
var tableHeader = ("Type".embraceWith("th") + "Model".embraceWith("th") + "Color".embraceWith("th")).embraceWith("tr");
var tableBody = results.map(function(item) {
return (item.type.embraceWith("td") + item.model.toString().embraceWith("td") + item.color.embraceWith("td")).embraceWith("tr")
}).join("");
var table = (tableHeader + tableBody).embraceWith("table");
$("#result-holder").append(table);
A non conventional method to separate javascript from the view, but still use razor in it is to make a Scripts.cshtml
file and place your mixed javascript/razor there.
Index.cshtml
<div id="Result">
</div>
<button id="btnLoad">Click me</button>
@section scripts
{
@Html.Partial("Scripts")
}
Scripts.cshtml
<script type="text/javascript">
var url = "@Url.Action("Index", "Home")";
$(document).ready(function() {
$("#btnLoad").click(function() {
$.ajax({
type: "POST",
url: url ,
data: {someParameter: "some value"},
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function(msg) {
$("#Result").text(msg.d);
}
});
});
});
</script>
I'd have thought you need to use a MessageFormat rather than DecimalFormat. That should be more flexible.
It worked for me too.

Eval is used to bind to an UI item that is setup to be read-only (eg: a label or a read-only text box), i.e., Eval is used for one way binding - for reading from a database into a UI field.
It is generally used for late-bound data (not known from start) and usually bound to the smallest part of the data-bound control that contains a whole record. The Eval method takes the name of a data field and returns a string containing the value of that field from the current record in the data source. You can supply an optional second parameter to specify a format for the returned string. The string format parameter uses the syntax defined for the Format method of the String class.
The approved answer from @jbochi does not work for me. The str() function call raises an exception because it cannot encode the non-ascii characters in the BeautifulSoup element. Here is a more succinct way to filter the example web page to visible text.
html = open('21storm.html').read()
soup = BeautifulSoup(html)
[s.extract() for s in soup(['style', 'script', '[document]', 'head', 'title'])]
visible_text = soup.getText()
Have you tried this?

Alternative for improved readability and using Map
and Reduce
:
const traveler = [
{ description: 'Senior', amount: 50 },
{ description: 'Senior', amount: 50 },
{ description: 'Adult', amount: 75 },
{ description: 'Child', amount: 35 },
{ description: 'Infant', amount: 25 },
];
const sum = traveler
.map(item => item.amount)
.reduce((prev, curr) => prev + curr, 0);
Re-useable function:
const calculateSum = (obj, field) => obj
.map(items => items.attributes[field])
.reduce((prev, curr) => prev + curr, 0);
Let's go over the basics: "Accessor" and "Mutator" are just fancy names fot a getter and a setter. A getter, "Accessor", returns a class's variable or its value. A setter, "Mutator", sets a class variable pointer or its value.
So first you need to set up a class with some variables to get/set:
public class IDCard
{
private String mName;
private String mFileName;
private int mID;
}
But oh no! If you instantiate this class the default values for these variables will be meaningless. B.T.W. "instantiate" is a fancy word for doing:
IDCard test = new IDCard();
So - let's set up a default constructor, this is the method being called when you "instantiate" a class.
public IDCard()
{
mName = "";
mFileName = "";
mID = -1;
}
But what if we do know the values we wanna give our variables? So let's make another constructor, one that takes parameters:
public IDCard(String name, int ID, String filename)
{
mName = name;
mID = ID;
mFileName = filename;
}
Wow - this is nice. But stupid. Because we have no way of accessing (=reading) the values of our variables. So let's add a getter, and while we're at it, add a setter as well:
public String getName()
{
return mName;
}
public void setName( String name )
{
mName = name;
}
Nice. Now we can access mName
. Add the rest of the accessors and mutators and you're now a certified Java newbie.
Good luck.
Jan. 2021: this is now possible for GitHub Enterprise (so: not yet for github.com).
See:
GitHub Pages now gives you the option to limit access, making the site visible only to users with access to the repository that published the Page.
With access control, you can use GitHub Pages to publish and share internal documentation and knowledge across your enterprise.
As part of this release, we are introducing the following capabilities:
- Repo admins can select whether GitHub Pages sites are publicly visible or limited to users who have access to the repository.
- Both private and internal repositories support private visibility. With an internal repository, everyone in your enterprise will be able to view the Page with the same credentials they use to login to github.com
- Org admins can configure the visibility options that members will be able to select for their Page. For example, you can enforce that your members can only publish content privately.
This feature is generally available today on GitHub Enterprise Cloud.
To enable access control on Pages, navigate to your repository settings, and click the dropdown menu to toggle between public and private visibility for your site.
I found this method: Matcher.replaceAll(String replacement); In java.util.regex.Matcher.java you can see more:
/**
* Replaces every subsequence of the input sequence that matches the
* pattern with the given replacement string.
*
* <p> This method first resets this matcher. It then scans the input
* sequence looking for matches of the pattern. Characters that are not
* part of any match are appended directly to the result string; each match
* is replaced in the result by the replacement string. The replacement
* string may contain references to captured subsequences as in the {@link
* #appendReplacement appendReplacement} method.
*
* <p> Note that backslashes (<tt>\</tt>) and dollar signs (<tt>$</tt>) in
* the replacement string may cause the results to be different than if it
* were being treated as a literal replacement string. Dollar signs may be
* treated as references to captured subsequences as described above, and
* backslashes are used to escape literal characters in the replacement

Short answer: classmaps are static while PSR autoloading is dynamic.
If you don't want to use classmaps, use PSR autoloading instead.

If you have a large array and only want to see a subsection of the array you can type this into the watch window;
ptr+100,10
to show a list of the 10 elements starting at ptr[100]. Beware that the displayed array subscripts will start at [0], so you will have to remember that ptr[0] is really ptr[100] and ptr[1] is ptr[101] etc.
In my case, it was because the images I used were stored on a Mac, which generates many hidden files like .image_file.png, so they turned out to not even be the actual images I needed and I could safely ignore the warning or delete the hidden files. It was just an oversight in my case.
Modified @CristianRomanescu code to work with memory stream, accept file as a byte array, allow null nvc, return request response and work with Authorization-header. Tested the code with Web Api 2.

if (nvc != null)
{
foreach (string key in nvc.Keys)
{
rs.Write(boundarybytes, 0, boundarybytes.Length);
string formitem = string.Format(formdataTemplate, key, nvc[key]);
byte[] formitembytes = System.Text.Encoding.UTF8.GetBytes(formitem);
rs.Write(formitembytes, 0, formitembytes.Length);
}
}
rs.Write(boundarybytes, 0, boundarybytes.Length);
string headerTemplate = "Content-Disposition: form-data; name=\"{0}\"; filename=\"{1}\"\r\nContent-Type: {2}\r\n\r\n";
string header = string.Format(headerTemplate, paramName, fileName, contentType);
byte[] headerbytes = System.Text.Encoding.UTF8.GetBytes(header);
rs.Write(headerbytes, 0, headerbytes.Length);
rs.Write(file, 0, file.Length);

Here is a short code snippet for shadowing cin/cout useful for programming contests:
#include <bits/stdc++.h>
using namespace std;
int main() {
ifstream cin("input.txt");
ofstream cout("output.txt");
int a, b;
cin >> a >> b;
cout << a + b << endl;
}
This gives additional benefit that plain fstreams are faster than synced stdio streams. But this works only for the scope of single function.
Global cin/cout redirect can be written as:
#include <bits/stdc++.h>
using namespace std;
void func() {
int a, b;
std::cin >> a >> b;
std::cout << a + b << endl;
}
int main() {
ifstream cin("input.txt");
ofstream cout("output.txt");
// optional performance optimizations
ios_base::sync_with_stdio(false);
std::cin.tie(0);
std::cin.rdbuf(cin.rdbuf());
std::cout.rdbuf(cout.rdbuf());
func();
}
Note that ios_base::sync_with_stdio
also resets std::cin.rdbuf
. So the order matters.
See also Significance of ios_base::sync_with_stdio(false); cin.tie(NULL);
Std io streams can also be easily shadowed for the scope of single file, which is useful for competitive programming:
#include <bits/stdc++.h>
using std::endl;
std::ifstream cin("input.txt");
std::ofstream cout("output.txt");
int a, b;
void read() {
cin >> a >> b;
}
void write() {
cout << a + b << endl;
}
int main() {
read();
write();
}
But in this case we have to pick std
declarations one by one and avoid using namespace std;
as it would give ambiguity error:
error: reference to 'cin' is ambiguous
cin >> a >> b;
^
note: candidates are:
std::ifstream cin
ifstream cin("input.txt");
^
In file test.cpp
std::istream std::cin
extern istream cin; /// Linked to standard input
^

With a modern JavaScript engine you can use Object.keys(driversCounter)
.
You would have to tune it according to your environment.
Sometimes it's more useful to increase the size of the backlog (acceptCount) instead of the maximum number of threads.
Say, instead of
<Connector ... maxThreads="500" acceptCount="50"
you use
<Connector ... maxThreads="300" acceptCount="150"
you can get much better performance in some cases, cause there would be less threads disputing the resources and the backlog queue would be consumed faster.
In any case, though, you have to do some benchmarks to really know what is best.
To get rid of the default dropdown arrow use:

If you are calling the sign_up API (AWS Cognito) using Python3, you can use the following code.
def registerUser(userObj):
''' Registers the user to AWS Cognito.
'''
# Mobile number is not a mandatory field.
if(len(userObj['user_mob_no']) == 0):
mobilenumber = ''
else:
mobilenumber = userObj['user_country_code']+userObj['user_mob_no']
secretKey = bytes(settings.SOCIAL_AUTH_COGNITO_SECRET, 'latin-1')
clientId = settings.SOCIAL_AUTH_COGNITO_KEY
digest = hmac.new(secretKey,
msg=(userObj['user_name'] + clientId).encode('utf-8'),
digestmod=hashlib.sha256
).digest()
signature = base64.b64encode(digest).decode()
client = boto3.client('cognito-idp', region_name='eu-west-1' )
try:
response = client.sign_up(
ClientId=clientId,
Username=userObj['user_name'],
Password=userObj['password1'],
SecretHash=signature,
UserAttributes=[
{
'Name': 'given_name',
'Value': userObj['given_name']
},
{

except ClientError as error:
return {"errorcode": error.response['Error']['Code'],
"errormessage" : error.response['Error']['Message'] }
except Exception as e:
return {"errorcode": "Something went wrong. Try later or contact the admin" }
return {"success": "User registered successfully. "}
error.response['Error']['Code'] will be InvalidPasswordException, UsernameExistsException etc. So in the main function or where you are calling the function, you can write the logic to provide a meaningful message to the user.
An example for the response (error.response):
{
"Error": {
"Message": "Password did not conform with policy: Password must have symbol characters",
"Code": "InvalidPasswordException"

Most things have been said already, but I can just add that I've used HSQL, Derby and Berkely DB in a few of my pet projects and they all worked just fine. So I don't think it really matters much to be honest. One thing worth mentioning is that HSQL saves itself as a text file with SQL statements which is quite good. Makes it really easy for when you are developing to do tests and setup data quickly. Can also do quick edits if needed. Guess you could easily transfer all that to any database if you ever need to change as well :)

Here are the three web pages on which we found the answer. The most difficult part was setting up static ports for SQLEXPRESS.
Provisioning a SQL Server Virtual Machine on Windows Azure. These initial instructions provided 25% of the answer.
How to Troubleshoot Connecting to the SQL Server Database Engine. Reading this carefully provided another 50% of the answer.
How to configure SQL server to listen on different ports on different IP addresses?. This enabled setting up static ports for named instances (eg SQLEXPRESS.) It took us the final 25% of the way to the answer.
Based on official documentation https://developer.android.com/studio/command-line/variables.html you should change ANDROID_AVD_HOME environment var:
Emulator Environment Variables
By default, the emulator stores configuration files under $HOME/.android/ and AVD data under $HOME/.android/avd/. You can override the defaults by setting the following environment variables. The emulator -avd command searches the avd directory in the order of the values in $ANDROID_AVD_HOME, $ANDROID_SDK_HOME/.android/avd/, and $HOME/.android/avd/. For emulator environment variable help, type emulator -help-environment at the command line. For information about emulator command-line options, see Control the Emulator from the Command Line.
- ANDROID_EMULATOR_HOME: Sets the path to the user-specific emulator configuration directory. The default location is
$ANDROID_SDK_HOME/.android/.- ANDROID_AVD_HOME: Sets the path to the directory that contains all AVD-specific files, which mostly consist of very large disk images. The default location is $ANDROID_EMULATOR_HOME/avd/. You might want to specify a new location if the default location is low on disk space.
After change or set ANDROID_AVD_HOME you will have to move all content inside ~user/.android/avd/ to your new location and change path into ini file of each emulator, just replace it with your new path
As jzd says, you can use System.currentTimeMillis
. If you need it in a Date
object but don't want to create a new Date
object, you can use Date.setTime
to reuse an existing Date
object. Personally I hate the fact that Date
is mutable, but maybe it's useful to you in this particular case. Similarly, Calendar
has a setTimeInMillis
method.
If possible though, it would probably be better just to keep it as a long
. If you only need a timestamp, effectively, then that would be the best approach.
yes you need to call repaint(); revalidate(); when you call removeAll() then you have to call repaint() and revalidate()
Generally this error arise when we send header after echoing or printing. If this error arise on a specific page then make sure that page is not echoing anything before calling to start_session().
Example of Unpredictable Error:
<?php //a white-space before <?php also send for output and arise error
session_start();
session_regenerate_id();
//your page content
One more example:
<?php
includes 'functions.php';
?> <!-- This new line will also arise error -->
<?php
session_start();
session_regenerate_id();
//your page content
Conclusion: Do not output any character before calling session_start() or header() functions not even a white-space or new-line
@{
viewbag.title="index"
Layout = null;
}
to make the difference between a refresh and a closed tab or navigator, here is how I fixed it :
<script>_x000D_
function endSession() {_x000D_
// Browser or Broswer tab is closed_x000D_
// Write code here_x000D_
}_x000D_
</script>_x000D_
_x000D_
<body onpagehide="endSession();">_x000D_
_x000D_
</body>
_x000D_
Not sure you resolved this issue or not, but this is how I do it and it works on Android:
You can using the following code:
if($(".parent a").attr('id')){
//do something
}
$(".parent a").each(function(i,e){
if($(e).attr('id')){
//do something and check
//if you want to break the each
//return false;
}
});
The same question is you can find here: how to check if div has id or not?
All good answers, but there's one difference I haven't seen mentioned yet, and that's how browsers render them by default. The major web browsers will render a <p>
tag with margin above and below the paragraph. A <div>
tag will be rendered without any margin at all.
There are a bunch of different ways depending on how far along you are and which branch(es) you want them on.
Let's take a classic mistake:
$ git checkout master
... pause for coffee, etc ...
... return, edit a bunch of stuff, then: oops, wanted to be on develop
So now you want these changes, which you have not yet committed to master
, to be on develop
.
If you don't have a develop
yet, the method is trivial:
$ git checkout -b develop
This creates a new develop
branch starting from wherever you are
now. Now you can commit and the new stuff is all on develop
.
You do have a develop
. See if Git will let you switch without
doing anything:
$ git checkout develop
This will either succeed, or complain. If it succeeds, great! Just
commit. If not (error: Your local changes to the following files would be overwritten ...
), you still have lots of options.
The easiest is probably git stash
(as all the other answer-ers
that beat me to clicking post said). Run git stash save
or git stash push
,1 or just plain git stash
which is short for save
/ push
:
$ git stash
This commits your code (yes, it really does make some commits) using a weird non-branch-y method. The commits it makes are not "on" any branch but are now safely stored in the repository, so you can now switch branches, then "apply" the stash:
$ git checkout develop
Switched to branch 'develop'
$ git stash apply
If all goes well, and you like the results, you should then git stash drop
the stash. This deletes the reference to the weird non-branch-y commits. (They're still in the repository, and can sometimes be retrieved in an emergency, but for most purposes, you should consider them gone at that point.)
The apply
step does a merge of the stashed changes, using Git's powerful underlying merge machinery, the same kind of thing it uses when you do branch merges. This means you can get "merge conflicts" if the branch you were working on by mistake, is sufficiently different from the branch you meant to be working on. So it's a good idea to inspect the results carefully before you assume that the stash applied cleanly, even if Git itself did not detect any merge conflicts.
Many people use git stash pop
, which is short-hand for git stash apply && git stash drop
. That's fine as far as it goes, but it means that if the application results in a mess, and you decide you don't want to proceed down this path, you can't get the stash back easily. That's why I recommend separate apply
, inspect results, drop
only if/when satisfied. (This does of course introduce another point where you can take another coffee break and forget what you were doing, come back, and do the wrong thing, so it's not a perfect cure.)
1The save
in git stash save
is the old verb for creating a new stash. Git version 2.13 introduced the new verb to make things more consistent with pop
and to add more options to the creation command. Git version 2.16 formally deprecated the old verb (though it still works in Git 2.23, which is the latest release at the time I am editing this).
A Hash function turns a variable-sized amount of text into a fixed-sized text.
Source: https://en.wikipedia.org/wiki/Hash_function
Hash functions in PHP
A hash turns a string to a hashed string. See below.
HASH:
$str = 'My age is 29';
$hash = hash('sha1', $str);
echo $hash; // OUTPUT: 4d675d9fbefc74a38c89e005f9d776c75d92623e
Passwords are usually stored in their hashed representation instead as readable text. When an end-user wants gain access to an application protected with a password then a password must be given during authentication. When the user submits his password, then the valid authentication system receives the password and hashes this given password. This password hash is compared to the hash known by the system. Access is granted in case of equality.
DEHASH:
SHA1 is a one-way hash. Which means that you can't dehash the hash.
However, you can brute-force the hash. Please see: https://hashkiller.co.uk/sha1-decrypter.aspx.
MD5, is another hash. A MD5 dehasher can be found on this website: https://www.md5online.org/.
To hamper brute-force attacks on hashes a salt can be given.
In php you can use password_hash()
for creating a password hash.
The function password_hash()
automatically creates a salt.
To verify a password on a password hash (with a salt) use password_verify()
.
// Invoke this little script 3 times, and it will give you everytime a new hash
$password = '1234';
$hash = password_hash($password, PASSWORD_DEFAULT);
echo $hash;
// OUTPUT
$2y$10$ADxKiJW/Jn2DZNwpigWZ1ePwQ4il7V0ZB4iPeKj11n.iaDtLrC8bu
$2y$10$H8jRnHDOMsHFMEZdT4Mk4uI4DCW7/YRKjfdcmV3MiA/WdzEvou71u
$2y$10$qhyfIT25jpR63vCGvRbEoewACQZXQJ5glttlb01DmR4ota4L25jaW
One password can be represented by more then one hash.
When you verify the password with different password hashes by using password_verify()
, then the password will be accepted as a valid password.
$password = '1234';
$hash = '$2y$10$ADxKiJW/Jn2DZNwpigWZ1ePwQ4il7V0ZB4iPeKj11n.iaDtLrC8bu';
var_dump( password_verify($password, $hash) );
$hash = '$2y$10$H8jRnHDOMsHFMEZdT4Mk4uI4DCW7/YRKjfdcmV3MiA/WdzEvou71u';
var_dump( password_verify($password, $hash) );
$hash = '$2y$10$qhyfIT25jpR63vCGvRbEoewACQZXQJ5glttlb01DmR4ota4L25jaW';
var_dump( password_verify($password, $hash) );
// OUTPUT

An Encryption function transforms a text into a nonsensical ciphertext by using an encryption key, and vice versa.
Source: https://en.wikipedia.org/wiki/Encryption
Encryption in PHP
Let's dive into some PHP code that handles encryption.
--- The Mcrypt extention ---
ENCRYPT:
$cipher = MCRYPT_RIJNDAEL_128;
$key = 'A_KEY';
$data = 'My age is 29';
$mode = MCRYPT_MODE_ECB;
$encryptedData = mcrypt_encrypt($cipher, $key , $data , $mode);
var_dump($encryptedData);
//OUTPUT:
string '„Ùòyªq³¿ì¼üÀpå' (length=16)
DECRYPT:
$decryptedData = mcrypt_decrypt($cipher, $key , $encryptedData, $mode);
$decryptedData = rtrim($decryptedData, "\0\4"); // Remove the nulls and EOTs at the END
var_dump($decryptedData);
//OUTPUT:
string 'My age is 29' (length=12)
--- The OpenSSL extention ---
The Mcrypt extention was deprecated in 7.1. and removed in php 7.2. The OpenSSL extention should be used in php 7. See the code snippets below:
$key = 'A_KEY';
$data = 'My age is 29';
// ENCRYPT
$encryptedData = openssl_encrypt($data , 'AES-128-CBC', $key, 0, 'IV_init_vector01');
var_dump($encryptedData);
// DECRYPT
$decryptedData = openssl_decrypt($encryptedData, 'AES-128-CBC', $key, 0, 'IV_init_vector01');
var_dump($decryptedData);
//OUTPUT
string '4RJ8+18YkEd7Xk+tAMLz5Q==' (length=24)
string 'My age is 29' (length=12)
(In an attempt to give a succinct yet complete derivation.)
Every input byte has 8 bits, so for n input bytes we get:
n Ă— 8 input bits
Every 6 bits is an output byte, so:
ceil(n Ă— 8 / 6) = ceil(n Ă— 4 / 3) output bytes
This is without padding.
With padding, we round that up to multiple-of-four output bytes:
ceil(ceil(n Ă— 4 / 3) / 4) Ă— 4 = ceil(n Ă— 4 / 3 / 4) Ă— 4 = ceil(n / 3) Ă— 4 output bytes
See Nested Divisions (Wikipedia) for the first equivalence.
Using integer arithmetics, ceil(n / m) can be calculated as (n + m – 1) div m, hence we get:
(n * 4 + 2) div 3 without padding
(n + 2) div 3 * 4 with padding
For illustration:
n with padding (n + 2) div 3 * 4 without padding (n * 4 + 2) div 3
------------------------------------------------------------------------------
0 0 0
1 AA== 4 AA 2
2 AAA= 4 AAA 3
3 AAAA 4 AAAA 4
4 AAAAAA== 8 AAAAAA 6
5 AAAAAAA= 8 AAAAAAA 7

10 AAAAAAAAAAAAAA== 16 AAAAAAAAAAAAAA 14
11 AAAAAAAAAAAAAAA= 16 AAAAAAAAAAAAAAA 15
12 AAAAAAAAAAAAAAAA 16 AAAAAAAAAAAAAAAA 16
Finally, in the case of MIME Base64 encoding, two additional bytes (CR LF) are needed per every 76 output bytes, rounded up or down depending on whether a terminating newline is required.
I am using as what John Rasch said:
Stream streamContent = taxformUpload.FileContent;
If you simply need a list, you could use:
List<Answer> answers = Arrays.asList(answer1, answer2, answer3);
If you specifically require an ArrayList
, you could use:
ArrayList<Answer> answers = new ArrayList(Arrays.asList(answer1, answer2, answer3));
Instead of trying to serve the node modules folder, you can also use Gulp to copy what you need to wwwroot.

Using the same approach of Philip Wallace, we can do like this:
public Control GetControlByName(Control ParentCntl, string NameToSearch)
{
if (ParentCntl.Name == NameToSearch)
return ParentCntl;
foreach (Control ChildCntl in ParentCntl.Controls)
{
Control ResultCntl = GetControlByName(ChildCntl, NameToSearch);
if (ResultCntl != null)
return ResultCntl;
}
return null;
}
Example:
public void doSomething()
{
TextBox myTextBox = (TextBox) this.GetControlByName(this, "mytextboxname");

If you need the exact functionality of the back button in your custom button, why not just call yourActivity.onBackPressed() that way if you override the functionality of the backbutton your custom button will behave the same.
ANDROID STUDIO Users try this:-
You need to add the following to your gradle file dependencies:
compile 'com.android.support:multidex:1.0.0'
And then add below line ( multidex support application ) to your manifest's application
tag:
android:name="android.support.multidex.MultiDexApplication"

Download a single file from a remote ftp server to your machine:
sftp {user}@{host}:{remoteFileName} {localFileName}
Upload a single file from your machine to a remote ftp server:
sftp {user}@{host}:{remote_dir} <<< $'put {local_file_path}'
Original answer:
Ok, so I feel a little dumb. But I figured it out. I almost had it at the top with:
sftp user@host remoteFile localFile
The only documentation shown in the terminal is this:
sftp [user@]host[:file ...]
sftp [user@]host[:dir[/]]
However, I came across this site which shows the following under the synopsis:
sftp [-vC1 ] [-b batchfile ] [-o ssh_option ] [-s subsystem | sftp_server ] [-B buffer_size ] [-F ssh_config ] [-P sftp_server path ] [-R num_requests ] [-S program ] host
sftp [[user@]host[:file [file]]]
sftp [[user@]host[:dir[/]]]
So the simple answer is you just do :
after your user and host then the remote file and local filename. Incredibly simple!
Single line, sftp copy remote file:
sftp username@hostname:remoteFileName localFileName
sftp kyle@kylesserver:/tmp/myLogFile.log /tmp/fileNameToUseLocally.log
Update Feb 2016
In case anyone is looking for the command to do the reverse of this and push a file from your local computer to a remote server in one single line sftp
command, user @Thariama below posted the solution to accomplish that. Hat tip to them for the extra code.
sftp {user}@{host}:{remote_dir} <<< $'put {local_file_path}'
Use clear: both;
I spent over a week trying to figure this out!
Just as a notice. I made a test function for my spreadsheet. I use the variable google throws in the onEdit(e) function (I called it e). Then I made a test function like this:
function test(){
var testRange = SpreadsheetApp.getActiveSpreadsheet().getSheetByName(GetItemInfoSheetName).getRange(2,7)
var testObject = {
range:testRange,
value:"someValue"
}
onEdit(testObject)
SpreadsheetApp.getActiveSpreadsheet().getSheetByName(GetItemInfoSheetName).getRange(2,6).setValue(Logger.getLog())
}
Calling this test function makes all the code run as you had an event in the spreadsheet. I just put in the possision of the cell i edited whitch gave me an unexpected result, setting value as the value i put into the cell. OBS! for more variables googles gives to the function go here: https://developers.google.com/apps-script/guides/triggers/events#google_sheets_events
For those who are using Oracle 12.1.0 for development purposes:
I found that the above methods would have no effect on the db user: "system", because the account_status would remain in the expired-grace period.
The easiest solution was for me to use SQL Developer:
within SQL Developer, I had to go to: View / DBA / Security and then Users / System and then on the right side: Actions / Expire pw and then: Actions / Edit and I could untick the option for expired.
This cleared the account_status, it shows OPEN again, and the SQL Developer is no longer showing the ORA-28002 message.
The documentation of MySQL says :
CREATE DATABASE creates a database with the given name. To use this statement, you need the CREATE privilege for the database. CREATE SCHEMA is a synonym for CREATE DATABASE as of MySQL 5.0.2.
So, it would seem normal that those two instruction do the same.
Warning
create_function()
has been DEPRECATED as of PHP 7.2.0. Relying on this function is highly discouraged.
You can use the array_map()
function.
This should do it:
$catIds = array_map(create_function('$o', 'return $o->id;'), $objects);
As @Relequestual writes below, the function is now integrated directly in the array_map. The new version of the solution looks like this:
$catIds = array_map(function($o) { return $o->id;}, $objects);
Add this style to your span:
position:relative;
top: 10px;
Other answers rightly point out that there is no need to use jQuery in order to navigate to another URL; that's why there's no jQuery function which does so!
If you're asking how to click a link via jQuery then assuming you have markup which looks like:
<a id="my-link" href="/relative/path.html">Click Me!</a>
You could click()
it by executing:
$('#my-link').click();
In general, the error ValueError: Wrong number of items passed 3, placement implies 1
suggests that you are attempting to put too many pigeons in too few pigeonholes. In this case, the value on the right of the equation
results['predictedY'] = predictedY
is trying to put 3 "things" into a container that allows only one. Because the left side is a dataframe column, and can accept multiple items on that (column) dimension, you should see that there are too many items on another dimension.
Here, it appears you are using sklearn for modeling, which is where gaussian_process.GaussianProcess()
is coming from (I'm guessing, but correct me and revise the question if this is wrong).
Now, you generate predicted values for y here:
predictedY, MSE = gp.predict(testX, eval_MSE = True)
However, as we can see from the documentation for GaussianProcess, predict()
returns two items. The first is y, which is array-like (emphasis mine). That means that it can have more than one dimension, or, to be concrete for thick headed people like me, it can have more than one column -- see that it can return (n_samples, n_targets)
which, depending on testX
, could be (1000, 3)
(just to pick numbers). Thus, your predictedY
might have 3 columns.
If so, when you try to put something with three "columns" into a single dataframe column, you are passing 3 items where only 1 would fit.
If a function does not return anything, e.g.:
def test():
pass
it has an implicit return value of None
.
Thus, as your pick*
methods do not return anything, e.g.:
def pickEasy():
word = random.choice(easyWords)
word = str(word)
for i in range(1, len(word) + 1):
wordCount.append("_")
the lines that call them, e.g.:
word = pickEasy()
set word
to None
, so wordInput
in getInput
is None
. This means that:
if guess in wordInput:
is the equivalent of:
if guess in None:
and None
is an instance of NoneType
which does not provide iterator/iteration functionality, so you get that type error.
The fix is to add the return type:
def pickEasy():
word = random.choice(easyWords)
word = str(word)
for i in range(1, len(word) + 1):
wordCount.append("_")
return word
Google Closure Compiler generally achieves smaller files than YUI Compressor, particularly if you use the advanced mode, which looks worryingly meddlesome to me but has worked well on the one project I've used it on:
Several big projects use UglifyJS, and I've been very impressed with it since switching.
For mysql you can add \p to the commands to have them print out while they run in the script:
SELECT COUNT(*) FROM `mysql`.`user`
\p;
Run it in the MySQL client:
mysql> source example.sql

SELECT COUNT(*) FROM `mysql`.`user`
--------------
+----------+
| COUNT(*) |
+----------+
| 24 |
+----------+
1 row in set (0.00 sec)
You can use HTML5 for this:
<video autoplay></video>
<script>
var onFailSoHard = function(e) {
console.log('Reeeejected!', e);
};
// Not showing vendor prefixes.
navigator.getUserMedia({video: true, audio: true}, function(localMediaStream) {
var video = document.querySelector('video');
video.src = window.URL.createObjectURL(localMediaStream);
// Note: onloadedmetadata doesn't fire in Chrome when using it with getUserMedia.
// See crbug.com/110938.
video.onloadedmetadata = function(e) {
// Ready to go. Do some stuff.
};
}, onFailSoHard);
</script>
If you are curious as to which is the most performant check this out where I compare all the different Number -> String conversions.
Looks like 2+''
or 2+""
are the fastest.
I was missing the MSVCR110.dll. Which I corrected. I could run php from the command line but not the web server. Then I clicked on php-cgi.exe and it gave me the answer. The php5.dll was missing (I downloaded the wrong copy). So for my 2012 IIS box I re-installed using php's x86 non thread safe zip.
First of all, link_to is a html tag helper, its second argument is the url, followed by html_options. What you would like is to pass account_id as a url parameter to the path. If you have set up named routes correctly in routes.rb, you can use path helpers.
link_to "+ Service", new_my_service_path(:account_id => acct.id)
I think the best practice is to pass model values as a param nested within :
link_to "+ Service", new_my_service_path(:my_service => { :account_id => acct.id })
# my_services_controller.rb
def new
@my_service = MyService.new(params[:my_service])
end
And you need to control that account_id is allowed for 'mass assignment'. In rails 3 you can use powerful controls to filter valid params within the controller where it belongs. I highly recommend.
http://apidock.com/rails/ActiveModel/MassAssignmentSecurity/ClassMethods
Also note that if account_id is not freely set by the user (e.g., a user can only submit a service for the own single account_id, then it is better practice not to send it via the request, but set it within the controller by adding something like:
@my_service.account_id = current_user.account_id
You can surely combine the two if you only allow users to create service on their own account, but allow admin to create anyone's by using roles in attr_accessible.
hope this helps
If you want to use the docker registry v2 API, it lists tags by pages. To list all the tags of an image, you may would like to add a large page_size parameter to the url, e.g.
curl -L -s 'https://registry.hub.docker.com/v2/repositories/library/centos/tags?page_size=1024'|jq '."results"[]["name"]'
Is it possible to select elements in CSS by their HTML5 data attributes? This can easily be answered just by trying it, and the answer is, of course, yes. But this invariably leads us to the next question, 'Should we select elements in CSS by their HTML5 data attributes?' There are conflicting opinions on this.
In the 'no' camp is (or at least was, back in 2014) CSS legend Harry Roberts. In the article, Naming UI components in OOCSS, he wrote:
It’s important to note that although we can style HTML via its data-* attributes, we probably shouldn’t. data-* attributes are meant for holding data in markup, not for selecting on. This, from the HTML Living Standard (emphasis mine):
"Custom data attributes are intended to store custom data private to the page or application, for which there are no more appropriate attributes or elements."
The W3C spec was frustratingly vague on this point, but based purely on what it did and didn't say, I think Harry's conclusion was perfectly reasonable.
Since then, plenty of articles have suggested that it's perfectly appropriate to use custom data attributes as styling hooks, including MDN's guide, Using data attributes. There's even a CSS methodology called CUBE CSS which has adopted the data attribute hook as the preferred way of adding styles to component 'exceptions' (known as modifiers in BEM).
Thankfully, the WHATWG HTML Living Standard has since added a few more words and even some examples (emphasis mine):
Custom data attributes are intended to store custom data, state, annotations, and similar, private to the page or application, for which there are no more appropriate attributes or elements.
In this example, custom data attributes are used to store the result of a feature detection for PaymentRequest, which could be used in CSS to style a checkout page differently.
Authors should carefully design such extensions so that when the attributes are ignored and any associated CSS dropped, the page is still usable.
TL;DR: Yes, it's okay to use data-*
attributes in CSS selectors, provided the page is still usable without them.
For debug/release flags, see the CMAKE_BUILD_TYPE
variable (you pass it as cmake -DCMAKE_BUILD_TYPE=value
). It takes values like Release
, Debug
, etc.
https://gitlab.kitware.com/cmake/community/wikis/doc/cmake/Useful-Variables#compilers-and-tools
cmake uses the extension to choose the compiler, so just name your files .c.
You can override this with various settings:
For example:
set_source_files_properties(yourfile.c LANGUAGE CXX)
Would compile .c files with g++. The link above also shows how to select a specific compiler for C/C++.
I have found that the 65536 limit still applies to pivot tables, even in Excel 2007.
you have three ways to enable CORS:
Enable CORS with named policy:
public class Startup
{
readonly string CorsPolicy = "_corsPolicy";
public void ConfigureServices(IServiceCollection services)
{
services.AddCors(options =>
{
options.AddPolicy(name: CorsPolicy,
builder =>
{
builder.AllowAnyOrigin()
.AllowAnyMethod()
.AllowAnyHeader()
.AllowCredentials();
});
});
// services.AddResponseCaching();
services.AddControllers();
}
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
app.UseRouting();
app.UseCors(CorsPolicy);
// app.UseResponseCaching();
app.UseAuthorization();
app.UseEndpoints(endpoints =>
{
endpoints.MapControllers();
});
}
}
UseCors must be called before UseResponseCaching when using UseResponseCaching.
Enable CORS with default policy:
public class Startup
{
public void ConfigureServices(IServiceCollection services)
{
services.AddCors(options =>
{
options.AddDefaultPolicy(
builder =>
{
builder.AllowAnyOrigin()
.AllowAnyMethod()
.AllowAnyHeader()
.AllowCredentials();
});
});
services.AddControllers();
}
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
app.UseRouting();
app.UseCors();
app.UseAuthorization();
app.UseEndpoints(endpoints =>
{
endpoints.MapControllers();
});
}
}
Enable CORS with endpoint
public class Startup
{
readonly string CorsPolicy = "_corsPolicy ";
public void ConfigureServices(IServiceCollection services)
{
services.AddCors(options =>
{
options.AddPolicy(name: CorsPolicy,
builder =>
{
builder.AllowAnyOrigin()
.AllowAnyMethod()
.AllowAnyHeader()
.AllowCredentials();
});
});
services.AddControllers();
}
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
app.UseRouting();
app.UseCors();
app.UseAuthorization();
app.UseEndpoints(endpoints =>
{
endpoints.MapControllers()
.RequireCors(CorsPolicy)
});
}
}
Enable CORS with attributes

Dominc has the right idea, but put the calculation on the other side of the expression.
SELECT * FROM my_table WHERE endTime < DATE_SUB(CONVERT_TZ(NOW(), @@global.time_zone, 'GMT'), INTERVAL 30 MINUTE)
This has the advantage that you're doing the 30 minute calculation once instead of on every row. That also means MySQL can use the index on that column. Both of thse give you a speedup.
I found for my particular setup the following commands worked
brew doctor
And then that showed me where my errors were, and then this slightly different command from the comment above.
sudo chown -R $(whoami) /usr/local/opt
To fix this solution i followed: this
1.Click Start and then type Run
2.Type services.msc and click OK
3.Scroll down the list and locate that the VMware Authorization service.
4.Click Start the service, unless the service is showing a status of Started.

Taking as a given you have a "large" number of data.frames with similar names (here d# where # is some positive integer), the following is a slight improvement of @mark-miller's method. It is more terse and returns a named list of data.frames, where each name in the list is the name of the corresponding original data.frame.
The key is using mget
together with ls
. If the data frames d1 and d2 provided in the question were the only objects with names d# in the environment, then
my.list <- mget(ls(pattern="^d[0-9]+"))
which would return
my.list
$d1
y1 y2
1 1 4
2 2 5
3 3 6
$d2
y1 y2
1 3 6
2 2 5
3 1 4
This method takes advantage of the pattern argument in ls
, which allows us to use regular expressions to do a finer parsing of the names of objects in the environment. An alternative to the regex "^d[0-9]+$"
is "^d\\d+$"
.
As @gregor points out, it is a better overall to set up your data construction process so that the data.frames are put into named lists at the start.
data
d1 <- data.frame(y1 = c(1,2,3),y2 = c(4,5,6))
d2 <- data.frame(y1 = c(3,2,1),y2 = c(6,5,4))
You should be able to do this via the command line arguments, assuming these are Sun VMs installed using the usual Windows InstallShield mechanisms with the JVM finder EXE in system32.

I needed to exclude an auditing @Aspect @Component from the app context but only for a few test classes. I ended up using @Profile("audit") on the aspect class; including the profile for normal operations but excluding it (don't put it in @ActiveProfiles) on the specific test classes.
I had a similar problem, but none of the solutions listed here helped. My problem was that my solution has multiple projects and the wrong one was selected as the StartUp Project, once I changed that, it worked.
Use a normal javascript timer:
$(function(){
function show_popup(){
$("#message").slideUp();
};
window.setTimeout( show_popup, 5000 ); // 5 seconds
});
This will wait 5 seconds after the DOM is ready. If you want to wait until the page is actually loaded
you need to use this:
$(window).load(function(){
function show_popup(){
$("#message").slideUp();
};
window.setTimeout( show_popup, 5000 ); // 5 seconds
})
EDIT: In answer to the OP's comment asking if there is a way to do it in jQuery and not use setTimeout
the answer is no. But if you wanted to make it more "jQueryish" you could wrap it like this:
$.wait = function( callback, seconds){
return window.setTimeout( callback, seconds * 1000 );
}
You could then call it like this:
$.wait( function(){ $("#message").slideUp() }, 5);
For your first question try
Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS);
(available since API 8)
To access individual files in this directory use either File.list() or File.listFiles(). Seems that reporting download progress is only possible in notification, see here.
Android Studio 3 Canary 1 has a new Device File Explorer
View -> Tool Windows -> Device File Explorer
So much better than DDMS and is the new improved way to get files off of your device!
Allows you to 'Open', 'Save As', 'Delete', 'Synchronize' and 'Copy Path'. Pretty awesome stuff!
this is how I implement it .
let dictionary = self.convertStringToDictionary(responceString)
NotificationCenter.default.post(name: NSNotification.Name(rawValue: "SOCKET_UPDATE"), object: dictionary)
Just let the activity background image be transparent. Or add the theme in the XML file:
<activity android:name=".usual.activity.Declaration" android:theme="@android:style/Theme.Translucent.NoTitleBar" />
This is what worked for me:
public static Map<String, Object> toMap(JSONObject jsonobj) throws JSONException {
Map<String, Object> map = new HashMap<String, Object>();
Iterator<String> keys = jsonobj.keys();
while(keys.hasNext()) {
String key = keys.next();
Object value = jsonobj.get(key);
if (value instanceof JSONArray) {
value = toList((JSONArray) value);
} else if (value instanceof JSONObject) {
value = toMap((JSONObject) value);
}
map.put(key, value);
} return map;
}
public static List<Object> toList(JSONArray array) throws JSONException {
List<Object> list = new ArrayList<Object>();
for(int i = 0; i < array.length(); i++) {
Object value = array.get(i);
if (value instanceof JSONArray) {
value = toList((JSONArray) value);
}
else if (value instanceof JSONObject) {
value = toMap((JSONObject) value);
}
list.add(value);
} return list;
}
Most of this is from this question: How to convert JSONObject to new Map for all its keys using iterator java
This works in Chrome:
p::after {
content: "-";
color: transparent;
display: block;
}
Login into the database. then run the below query
select * from dba_role_privs where grantee = 'SCHEMA_NAME';
All the role granted to the schema will be listed.
Thanks Szilagyi Donat for the answer. This one is taken from same and just where clause added.
Try this:
MyContext Context = new MyContext();
Context.YourEntity.Add(obj);
Context.SaveChanges();
int ID = obj._ID;
Well if you want fully transparent than you can use
border: 5px solid transparent;
If you mean opaque/transparent, than you can use
border: 5px solid rgba(255, 255, 255, .5);
Here, a
means alpha, which you can scale, 0-1.
Also some might suggest you to use opacity
which does the same job as well, the only difference is it will result in child elements getting opaque too, yes, there are some work arounds but rgba
seems better than using opacity
.
For older browsers, always declare the background color using #
(hex) just as a fall back, so that if old browsers doesn't recognize the rgba
, they will apply the hex
color to your element.

Note (For Demo 3): Image will be scaled according to the height and width provided so make sure it doesn't break the scaling ratio.
Can someone please tell me how to create a static library from a .cpp and a .hpp file? Do I need to create the .o and the the .a?
Yes.
Create the .o (as per normal):
g++ -c header.cpp
Create the archive:
ar rvs header.a header.o
Test:
g++ test.cpp header.a -o executable_name
Note that it seems a bit pointless to make an archive with just one module in it. You could just as easily have written:
g++ test.cpp header.cpp -o executable_name
Still, I'll give you the benefit of the doubt that your actual use case is a bit more complex, with more modules.
Hope this helps!
I use the PHP_EOL constant in some command line scripts I had to write. I develop on my local Windows machine and then test on a Linux server box. Using the constant meant I didn't have to worry about using the correct line ending for each of the different platforms.
I have also met the same problem using rbenv + passenger + nginx. my solution is simply adding these 2 line of code to your nginx config:

The for-in
statement by itself is not a "bad practice", however it can be mis-used, for example, to iterate over arrays or array-like objects.
The purpose of the for-in
statement is to enumerate over object properties. This statement will go up in the prototype chain, also enumerating over inherited properties, a thing that sometimes is not desired.
Also, the order of iteration is not guaranteed by the spec., meaning that if you want to "iterate" an array object, with this statement you cannot be sure that the properties (array indexes) will be visited in the numeric order.
For example, in JScript (IE <= 8), the order of enumeration even on Array objects is defined as the properties were created:
var array = [];
array[2] = 'c';
array[1] = 'b';
array[0] = 'a';
for (var p in array) {
//... p will be "2", "1" and "0" on IE
}
Also, speaking about inherited properties, if you, for example, extend the Array.prototype
object (like some libraries as MooTools do), that properties will be also enumerated:
Array.prototype.last = function () { return this[this.length-1]; };
for (var p in []) { // an empty array
// last will be enumerated
}
As I said before to iterate over arrays or array-like objects, the best thing is to use a sequential loop, such as a plain-old for
/while
loop.
When you want to enumerate only the own properties of an object (the ones that aren't inherited), you can use the hasOwnProperty
method:
for (var prop in obj) {
if (obj.hasOwnProperty(prop)) {
// prop is not inherited
}
}
And some people even recommend calling the method directly from Object.prototype
to avoid having problems if somebody adds a property named hasOwnProperty
to our object:
for (var prop in obj) {
if (Object.prototype.hasOwnProperty.call(obj, prop)) {
// prop is not inherited
}
}
To merge the two arrays on id
, assuming the arrays are equal length:
arr1.map(item => ({
...item,
...arr2.find(({ id }) => id === item.id),
}));
This is the intended use case for Ray, which is a library for parallel and distributed Python. Under the hood, it serializes objects using the Apache Arrow data layout (which is a zero-copy format) and stores them in a shared-memory object store so they can be accessed by multiple processes without creating copies.
The code would look like the following.
import numpy as np
import ray
ray.init()
@ray.remote
def func(array, param):
# Do stuff.
return 1
array = np.ones(10**6)
# Store the array in the shared memory object store once
# so it is not copied multiple times.
array_id = ray.put(array)
result_ids = [func.remote(array_id, i) for i in range(4)]
output = ray.get(result_ids)
If you don't call ray.put
then the array will still be stored in shared memory, but that will be done once per invocation of func
, which is not what you want.
Note that this will work not only for arrays but also for objects that contain arrays, e.g., dictionaries mapping ints to arrays as below.
You can compare the performance of serialization in Ray versus pickle by running the following in IPython.
import numpy as np
import pickle
import ray
ray.init()
x = {i: np.ones(10**7) for i in range(20)}
# Time Ray.
%time x_id = ray.put(x) # 2.4s
%time new_x = ray.get(x_id) # 0.00073s
# Time pickle.
%time serialized = pickle.dumps(x) # 2.6s
%time deserialized = pickle.loads(serialized) # 1.9s
Serialization with Ray is only slightly faster than pickle, but deserialization is 1000x faster because of the use of shared memory (this number will of course depend on the object).
See the Ray documentation. You can read more about fast serialization using Ray and Arrow. Note I'm one of the Ray developers.

If you getting a blank screen, that may be because of 2 reasons:
Browser blocking the Frames from being displayed. In some browsers the frames are considered as unsafe. To overcome this you can launch the frameless version of phpPgAdmin by

You have enabled a security feature in Nginx for X-Frame-Options try disabling it.
For example in my case I accidentaly changed role of some users to incorrect, and my application got error during starting (NullReferenceException). When I fixed it - the app starts fine.
Yes, you can.

OSX users can follow by Nicolay77 or mikkom that uses the mdbtools utility. You can install it via Homebrew. Just have your homebrew installed and then go
$ homebrew install mdbtools
Then create one of the scripts described by the guys and use it. I've used mikkom's one, converted all my mdb files into sql.
$ ./to_mysql.sh myfile.mdb > myfile.sql
(which btw contains more than 1 table)
import * as express from "express";
This is the suggested way of doing it because it is the standard for JavaScript (ES6/2015) since last year.
In any case, in your tsconfig.json file, you should target the module option to commonjs which is the format supported by nodejs.
You may need to install ATL if your COM objects use ATL, as described by this KB article:

These libraries will probably have to be supplied by developers to ensure the correct version.
I like to think about interfaces and implementations of interfaces. In C++ speak interface is pure virtual class. Destructor is part of the interface and expected to implemented. Therefore destructor should be pure virtual. How about constructor? Constructor is actually not part of the interface because object is always instantiated explicitly.
It's hard to infer what you're looking for from the question, but my best guess is as follows.
If we assume you have a DataFrame where some column is 'Category' and contains integers (or otherwise unique identifiers) for categories, then we can do the following.
Call the DataFrame dfrm
, and assume that for each row, dfrm['Category']
is some value in the set of integers from 1 to N. Then,
for elem in dfrm['Category'].unique():
dfrm[str(elem)] = dfrm['Category'] == elem
Now there will be a new indicator column for each category that is True/False depending on whether the data in that row are in that category.
If you want to control the category names, you could make a dictionary, such as
cat_names = {1:'Some_Treatment', 2:'Full_Treatment', 3:'Control'}
for elem in dfrm['Category'].unique():
dfrm[cat_names[elem]] = dfrm['Category'] == elem
to result in having columns with specified names, rather than just string conversion of the category values. In fact, for some types, str()
may not produce anything useful for you.
xfs_mkfile 10240m 10Gigfile
fallocate -l 10G 10Gigfile
mkfile 10240m 10Gigfile
prealloc 10Gigfile 10737418240
Try mkfile <size>
myfile as an alternative of dd
. With the -n
option the size is noted, but disk blocks aren't allocated until data is written to them. Without the -n
option, the space is zero-filled, which means writing to the disk, which means taking time.
mkfile is derived from SunOS and is not available everywhere. Most Linux systems have xfs_mkfile
which works exactly the same way, and not just on XFS file systems despite the name. It's included in xfsprogs (for Debian/Ubuntu) or similar named packages.
Most Linux systems also have fallocate
, which only works on certain file systems (such as btrfs, ext4, ocfs2, and xfs), but is the fastest, as it allocates all the file space (creates non-holey files) but does not initialize any of it.
You can use the hasClass
method, eg.
$('li.menu').hasClass('active') // true|false
Or if you want to select it in one go, you can use:
$('li.menu.active')
So, you want an 8-character wide field with spaces as the padding? Try "%8d". Here's a reference.
EDIT: What you're trying to do is not something that can be handled by printf alone, because it will not know what the longest number you are writing is. You will need to calculate the largest number before doing any printfs, and then figure out how many digits to use as the width of your field. Then you can use snprintf or similar to make a printf format on the spot.
char format[20];
snprintf(format, 19, "%%%dd\\n", max_length);
while (got_output) {
printf(format, number);
got_output = still_got_output();
}
Python's csv module handles data row-wise, which is the usual way of looking at such data. You seem to want a column-wise approach. Here's one way of doing it.
Assuming your file is named myclone.csv
and contains
workers,constant,age
w0,7.334,-1.406
w1,5.235,-4.936
w2,3.2225,-1.478
w3,0,0
this code should give you an idea or two:
>>> import csv
>>> f = open('myclone.csv', 'rb')
>>> reader = csv.reader(f)
>>> headers = next(reader, None)
>>> headers
['workers', 'constant', 'age']
>>> column = {}
>>> for h in headers:
... column[h] = []
...
>>> column
{'workers': [], 'constant': [], 'age': []}
>>> for row in reader:
... for h, v in zip(headers, row):
... column[h].append(v)
...
>>> column
{'workers': ['w0', 'w1', 'w2', 'w3'], 'constant': ['7.334', '5.235', '3.2225', '0'], 'age': ['-1.406', '-4.936', '-1.478', '0']}
>>> column['workers']
['w0', 'w1', 'w2', 'w3']
>>> column['constant']
['7.334', '5.235', '3.2225', '0']
>>> column['age']
['-1.406', '-4.936', '-1.478', '0']
>>>
To get your numeric values into floats, add this
converters = [str.strip] + [float] * (len(headers) - 1)
up front, and do this
for h, v, conv in zip(headers, row, converters):
column[h].append(conv(v))
for each row instead of the similar two lines above.
InverseProperty
in EF Core makes the solution easy and clean.
So the desired solution would be:
public class Team
{
[Key]
public int TeamId { get; set;}
public string Name { get; set; }
[InverseProperty(nameof(Match.HomeTeam))]
public ICollection<Match> HomeMatches{ get; set; }
[InverseProperty(nameof(Match.GuestTeam))]
public ICollection<Match> AwayMatches{ get; set; }
}
public class Match
{
[Key]
public int MatchId { get; set; }
[ForeignKey(nameof(HomeTeam)), Column(Order = 0)]
public int HomeTeamId { get; set; }
[ForeignKey(nameof(GuestTeam)), Column(Order = 1)]
public int GuestTeamId { get; set; }
public float HomePoints { get; set; }
public float GuestPoints { get; set; }
public DateTime Date { get; set; }
public Team HomeTeam { get; set; }
public Team GuestTeam { get; set; }
}
Some Google services do not like to be used to much. Quite recently my account was locked because of script, which was sending two e-mails per second to the same user. Google considered it as a spam. So using sleep here is also justified to prevent such situations.
Use:
from datetime import datetime
today = datetime.today()
datem = datetime(today.year, today.month, 1)
I assume you want the first of the month.
Why do you use new Date instead of a static UTC string?
function clearListCookies(){
var cookies = document.cookie.split(";");
for (var i = 0; i < cookies.length; i++){
var spcook = cookies[i].split("=");
document.cookie = spcook[0] + "=;expires=Thu, 21 Sep 1979 00:00:01 UTC;";
}
}
An alternative solution would be to use some sort of regex
:
for example:
String s = "apple car 04:48 05:18 05:46 06:16 06:46 07:16 07:46 16:46 17:16 17:46 18:16 18:46 19:16";
String results= s.replaceAll("[0-9]", "").replaceAll(" :", ""); //first removing all the numbers then remove space followed by :
System.out.println(results); // output 9
System.out.println(results.length());// output "apple car"
so long as your html content doesn't need to contain a CDATA

The commands dict.items()
, dict.keys()
and dict.values()
return a copy of the dictionary's list of (k, v)
pair, keys and values.
This could take a lot of memory if the copied list is very large.
The commands dict.iteritems()
, dict.iterkeys()
and dict.itervalues()
return an iterator over the dictionary’s (k, v)
pair, keys and values.
The commands dict.viewitems()
, dict.viewkeys()
and dict.viewvalues()
return the view objects, which can reflect the dictionary's changes.
(I.e. if you del
an item or add a (k,v)
pair in the dictionary, the view object can automatically change at the same time.)
$ python2.7
>>> d = {'one':1, 'two':2}
>>> type(d.items())
<type 'list'>
>>> type(d.keys())
<type 'list'>
>>>
>>>
>>> type(d.iteritems())
<type 'dictionary-itemiterator'>
>>> type(d.iterkeys())
<type 'dictionary-keyiterator'>
>>>
>>>
>>> type(d.viewitems())
<type 'dict_items'>
>>> type(d.viewkeys())
<type 'dict_keys'>
In Py3.x, things are more clean, since there are only dict.items()
, dict.keys()
and dict.values()
available, which return the view objects just as dict.viewitems()
in Py2.x did.
Just as @lvc noted, view object isn't the same as iterator, so if you want to return an iterator in Py3.x, you could use iter(dictview)
:
$ python3.3
>>> d = {'one':'1', 'two':'2'}
>>> type(d.items())
<class 'dict_items'>
>>>
>>> type(d.keys())
<class 'dict_keys'>
>>>
>>>
>>> ii = iter(d.items())
>>> type(ii)
<class 'dict_itemiterator'>
>>>
>>> ik = iter(d.keys())
>>> type(ik)
<class 'dict_keyiterator'>
You can get the file name, but you cannot get the full client file-system path.
Try to access to the value
attribute of your file input
on the change
event.
Most browsers will give you only the file name, but there are exceptions like IE8 which will give you a fake path like: "C:\fakepath\myfile.ext"
and older versions (IE <= 6) which actually will give you the full client file-system path (due its lack of security).
document.getElementById('fileInput').onchange = function () {
alert('Selected file: ' + this.value);
};
For example => TestController
[HttpGet]
public string TestMethod(int arg0)
{
return "";
}
[HttpGet]
public string TestMethod2(string arg0)
{
return "";
}
[HttpGet]
public string TestMethod3(int arg0,string arg1)
{
return "";
}
If you can only change WebApiConfig.cs file.

You haven't been very specific with your code, so I'll make up a scenario. Let's say you have 10 ajax calls and you want to accumulate the results from those 10 ajax calls and then when they have all completed you want to do something. You can do it like this by accumulating the data in an array and keeping track of when the last one has finished:
Manual Counter
var ajaxCallsRemaining = 10;
var returnedData = [];
for (var i = 0; i < 10; i++) {
doAjax(whatever, function(response) {
// success handler from the ajax call
// save response
returnedData.push(response);
// see if we're done with the last ajax call
--ajaxCallsRemaining;
if (ajaxCallsRemaining <= 0) {
// all data is here now
// look through the returnedData and do whatever processing
// you want on it right here
}
});
}
Note: error handling is important here (not shown because it's specific to how you're making your ajax calls). You will want to think about how you're going to handle the case when one ajax call never completes, either with an error or gets stuck for a long time or times out after a long time.
jQuery Promises
Adding to my answer in 2014. These days, promises are often used to solve this type of problem since jQuery's $.ajax()
already returns a promise and $.when()
will let you know when a group of promises are all resolved and will collect the return results for you:
var promises = [];
for (var i = 0; i < 10; i++) {
promises.push($.ajax(...));
}
$.when.apply($, promises).then(function() {
// returned data is in arguments[0][0], arguments[1][0], ... arguments[9][0]
// you can process it here
}, function() {
// error occurred
});
ES6 Standard Promises
As specified in kba's answer: if you have an environment with native promises built-in (modern browser or node.js or using babeljs transpile or using a promise polyfill), then you can use ES6-specified promises. See this table for browser support. Promises are supported in pretty much all current browsers, except IE.
If doAjax()
returns a promise, then you can do this:
var promises = [];
for (var i = 0; i < 10; i++) {
promises.push(doAjax(...));
}
Promise.all(promises).then(function() {
// returned data is in arguments[0], arguments[1], ... arguments[n]
// you can process it here
}, function(err) {
// error occurred
});
If you need to make a non-promise async operation into one that returns a promise, you can "promisify" it like this:
function doAjax(...) {
return new Promise(function(resolve, reject) {
someAsyncOperation(..., function(err, result) {
if (err) return reject(err);
resolve(result);
});
});
}
And, then use the pattern above:
var promises = [];
for (var i = 0; i < 10; i++) {
promises.push(doAjax(...));
}
Promise.all(promises).then(function() {
// returned data is in arguments[0], arguments[1], ... arguments[n]
// you can process it here
}, function(err) {
// error occurred
});
Bluebird Promises
If you use a more feature rich library such as the Bluebird promise library, then it has some additional functions built in to make this easier:
var doAjax = Promise.promisify(someAsync);
var someData = [...]
Promise.map(someData, doAjax).then(function(results) {
// all ajax results here
}, function(err) {
// some error here
});
This can also happen when you mix -fno-rtti
and -frtti
code. Then you need to ensure that any class, which type_info
is accessed in the -frtti
code, have their key method compiled with -frtti
. Such access can happen when you create an object of the class, use dynamic_cast
etc.
[source]
Best way to do this is to use a function:
html
<div ng-repeat="product in products | filter: myFilter">
javascript
$scope.myFilter = function (item) {
return item === 'red' || item === 'blue';
};
Alternatively, you can use ngHide or ngShow to dynamically show and hide elements based on a certain criteria.
I use
Select COUNT(*) As X From INFORMATION_SCHEMA.SYSTEM_USERS Where 1=0
for hsqldb 1.8.0
Try putting this HTML snippet into your served document:
<img id="ItemPreview" src="">
Then, on JavaScript side, you can dynamically modify image's src
attribute with so-called Data URL.
document.getElementById("ItemPreview").src = "data:image/png;base64," + yourByteArrayAsBase64;
Alternatively, using jQuery:
$('#ItemPreview').attr('src', `data:image/png;base64,${yourByteArrayAsBase64}`);
This assumes that your image is stored in PNG format, which is quite popular. If you use some other image format (e.g. JPEG), modify the MIME type ("image/..."
part) in the URL accordingly.

I found this question because I was having issues with the OPTIONS request most browsers send. My app was routing the OPTIONS requests and using my IoC to construct lots of objects and some were throwing exceptions on this odd request type for various reasons.
Basically put in an ignore route for all OPTIONS requests if they are causing you problems:
var constraints = new { httpMethod = new HttpMethodConstraint(HttpMethod.Options) };
config.Routes.IgnoreRoute("OPTIONS", "{*pathInfo}", constraints);

data.table
has a really intuitive way of doing this as well:
library(data.table)
sample_fxn = function(x,y,z){
return((x+y)*z)
}
df = data.table(A = 1:5,B=seq(2,10,2),C = 6:10)
> df
A B C
1: 1 2 6
2: 2 4 7
3: 3 6 8
4: 4 8 9
5: 5 10 10
The :=
operator can be called within brackets to add a new column using a function
df[,new_column := sample_fxn(A,B,C)]
> df
A B C new_column
1: 1 2 6 18
2: 2 4 7 42
3: 3 6 8 72
4: 4 8 9 108
5: 5 10 10 150
It's also easy to accept constants as arguments as well using this method:
df[,new_column2 := sample_fxn(A,B,2)]
> df
A B C new_column new_column2
1: 1 2 6 18 6
2: 2 4 7 42 12

I would recommend using a cursor. A cursor fetch is always a single row (unless you use a bulk collection), and cursors do not automatically throw no_data_found or too_many_rows exceptions; although you may inspect the cursor attribute once opened to determine if you have a row and how many.
declare
v_column my_table.column%type;
l_count pls_integer;
cursor my_cursor is
select count(*) from my_table where ...;
begin
open my_cursor;
fetch my_cursor into l_count;
close my_cursor;
if l_count = 1 then
select whse_code into v_column from my_table where ...;
else
v_column := null;
end if;
end;
Or, even more simple:
declare
v_column my_table.column%type;
cursor my_cursor is
select column from my_table where ...;
begin
open my_cursor;
fetch my_cursor into v_column;
-- Optional IF .. THEN based on FOUND or NOTFOUND
-- Not really needed if v_column is not set
if my_cursor%notfound then
v_column := null;
end if;
close my_cursor;
end;

{
sign = '-';
f *= -1;
}
number2 = f;
number = f;
length = 0; // Size of decimal part
length2 = 0; // Size of tenth
/* Calculate length2 tenth part */
while( (number2 - (float)number) != 0.0 && !((number2 - (float)number) < 0.0) )
{
number2 = f * (n_tu(10.0, length2 + 1));
number = number2;
length2++;
}
/* Calculate length decimal part */
for (length = (f > 1) ? 0 : 1; f > 1; length++)
f /= 10;
position = length;
length = length + 1 + length2;
number = number2;
if (sign == '-')
{

}
for (i = length; i >= 0 ; i--)

To create a clickable reference to a channel in a Slack conversation, just type #
followed by the channel name. For example: #general
.
To share the channel URL externally, you can grab its link by control-clicking (Mac) or right-clicking (Windows) on the channel name:
The link would look like this:
https://yourteam.slack.com/messages/C69S1L3SS
Note that this link doesn't change even if you change the name of the channel. So, it is better to use this link rather than the one based on channel's name.
https://yourteam.slack.com/channels/<channel_name>
Opening the above URL from a browser would launch the Slack client (if available) or open the slack channel on the browser itself.
https://yourteam.slack.com/channels/<username>

If you only want to change the font in the TEXTAREA then you only need to change the changeFont() function in the original code to:
function changeFont(_name) {

Then selecting a font will change on the font only in the TEXTAREA.

Import your server certificate into your trustcacerts keystore on client's JRE. This is easily done with keytool:
keytool
-import
-alias <provide_an_alias>
-file <certificate_file>
-keystore <your_path_to_jre>/lib/security/cacerts

Recently ran into a problem with this and a Chrome extension that was corrupting a JSON stream when the response header labeled the content-type as 'text/html' apparently extensions can and will use the response header to alter the content prior to further processing by the browser. Changing the content-type fixed the issue.
You would need to do this since slice
doesn't alter the original array.
arr = arr.slice(-1);
If you want to alter the original array you can use splice
:
arr.splice(-1, 1);
or pop
:
arr.pop();
You can also just return string if you know that's the only thing the method will ever return. For example:
public string MyActionName() {
return "Hi there!";
}
For simple integer arithmetic, you can also use the builtin let command.
ONE=1
TWO=2
let "THREE = $ONE + $TWO"
echo $THREE
3
For more info on let
, look here.
If you wanna add dynamic width and height based on your device frame, you can do these calculations and assign the height and width.
AlertDialog.Builder builderSingle = new
AlertDialog.Builder(getActivity());
builderSingle.setTitle("Title");
final AlertDialog alertDialog = builderSingle.create();
alertDialog.show();
Rect displayRectangle = new Rect();
Window window = getActivity().getWindow();
window.getDecorView().getWindowVisibleDisplayFrame(displayRectangle);
alertDialog.getWindow().setLayout((int)(displayRectangle.width() *
0.8f), (int)(displayRectangle.height() * 0.8f));
P.S : Show the dialog first and then try to modify the window's layout attributes
I have stumbled across this question and I will submit my answer that I used and worked pretty well. I had a search box that filtered and array of objects and on my search box I used the (ngModelChange)="onChange($event)"
in my .html
<input type="text" [(ngModel)]="searchText" (ngModelChange)="reSearch(newValue)" placeholder="Search">
then in my component.ts
reSearch(newValue: string) {
//this.searchText would equal the new value
//handle my filtering with the new value
}

Edit Jan 2021: The React Native docs currently recommend React Native WebView:
<WebView
originWhitelist={['*']}
source={{ html: '<p>Here I am</p>' }}
/>
https://github.com/react-native-webview/react-native-webview
Edit March 2017: the html
prop has been deprecated. Use source
instead:
<WebView source={{html: '<p>Here I am</p>'}} />
https://facebook.github.io/react-native/docs/webview.html#html
Thanks to Justin for pointing this out.
Edit Feb 2017: the PR was accepted a while back, so to render HTML in React Native, simply:
<WebView html={'<p>Here I am</p>'} />
Original Answer:
I don't think this is currently possible. The behavior you're seeing is expected, since the Text component only outputs... well, text. You need another component that outputs HTML - and that's the WebView.
Unfortunately right now there's no way of just directly setting the HTML on this component:
https://github.com/facebook/react-native/issues/506
However I've just created this PR which implements a basic version of this feature so hopefully it'll land in some form soonish.
This one seems to be a better fit:
<#if userName?has_content>
... do something
</#if>

Why do you need a console application if you want to hide console itself? =)
I recommend setting Project Output type to Windows Application instead of Console application. It will not show you console window, but execute all actions, like Console application do.
This is fairly trivial to do with Array.prototype.reduce
:
var arr = [_x000D_
{ key: 'foo', val: 'bar' },_x000D_
{ key: 'hello', val: 'world' }_x000D_
];_x000D_
_x000D_
var result = arr.reduce(function(map, obj) {_x000D_
map[obj.key] = obj.val;_x000D_
return map;_x000D_
}, {});_x000D_
_x000D_
console.log(result);_x000D_
// { foo:'bar', hello:'world' }
_x000D_
Note: Array.prototype.reduce()
is IE9+, so if you need to support older browsers you will need to polyfill it.
Actually, CheckBoxPreference does have the ability to specify a different summary based on the checkbox value. See the android:summaryOff and android:summaryOn attributes (as well as the corresponding CheckBoxPreference methods).
Core Java is Sun Microsystem's, used to refer to Java SE. And there are Java ME and Java EE (J2EE). So this is told in order to differentiate with the Java ME and J2EE. So I feel Core Java is only used to mention J2SE.
Java having 3 category:
J2SE(Java to Standard Edition) - Core Java
J2EE(Java to Enterprises Edition)- Advance Java + Framework
J2ME(Java to Micro Edition)
Thank You..
Not a direct answer to your question, but using <tfoot> might help you achieve what you need, and of course you can style tfoot.
For nearly all programming purposes, VBA and VB 6.0 are the same thing.
VBA cannot compile your program into an executable binary. You'll always need the host (a Word file and MS Word, for example) to contain and execute your project. You'll also not be able to create COM DLLs with VBA.
Apart from that, there is a difference in the IDE - the VB 6.0 IDE is more powerful in comparison. On the other hand, you have tight integration of the host application in VBA. Application-global objects (like "ActiveDocument") and events are available without declaration, so application-specific programming is straight-forward.
Still, nothing keeps you from firing up Word, loading the VBA IDE and solving a problem that has no relation to Word whatsoever. I'm not sure if there is anything that VB 6.0 can do (technically), and VBA cannot. I'm looking for a comparison sheet on the MSDN though.
If you want to list the indexes of all the tables in your schema(s) from your program, all the information is on hand in the catalog:
select
n.nspname as "Schema"
,t.relname as "Table"
,c.relname as "Index"
from
pg_catalog.pg_class c
join pg_catalog.pg_namespace n on n.oid = c.relnamespace
join pg_catalog.pg_index i on i.indexrelid = c.oid
join pg_catalog.pg_class t on i.indrelid = t.oid
where
c.relkind = 'i'
and n.nspname not in ('pg_catalog', 'pg_toast')
and pg_catalog.pg_table_is_visible(c.oid)
order by
n.nspname
,t.relname
,c.relname
If you want to delve further (such as columns and ordering), you need to look at pg_catalog.pg_index. Using psql -E [dbname]
comes in handy for figuring out how to query the catalog.
