I dont know if you solved this issue, but i had same issue, if the instance is local you must check the permission to access the file, but if you are accessing from your computer to a server (remote access) you have to specify the path in the server, so that means to include the file in a server directory, that solved my case
example:
BULK INSERT Table
FROM 'C:\bulk\usuarios_prueba.csv' -- This is server path not local
WITH
(
FIELDTERMINATOR =',',
ROWTERMINATOR ='\n'
);
Active Directory is refusing access to your SQL Agent. The Agent should be running under an account that is recognized by STAR domain controller.
You just need to add this line to the window there:
exec (your stored proc name) (and possibly add parameters)
What is your stored proc called, and what parameters does it expect?
An easy way without fixed width:
.myTable tbody{
display:block;
overflow:auto;
height:200px;
width:100%;
}
.myTable thead tr{
display:block;
}
Now, on onLoad, to adjust th widths, just add this jquery script:
$.each($('.myTable tbody tr:nth(0) td'), function(k,v) {
$('.myTable thead th:nth('+k+')').css('width', $(v).css('width'));
});
If you need use it as a default configuration, just place min: 0
inside the node defaults.scale.ticks
, as follows:
defaults: {
global: {...},
scale: {
...
ticks: { min: 0 },
}
},

A similar question is: Mapping a NumPy array in place. If you can find a ufunc for your f(), then you should use the out parameter.
There is a limit on the number of half-open connections, but afaik not for active connections. Although it appears to depend on the type of Windows 2008 server, at least according to this MSFT employee:
It depends on the edition, Web and Foundation editions have connection limits while Standard, Enterprise, and Datacenter do not.
I had the same problem and in my case .project
file was also present in the project directory and had correct permissions.
This problem happened to me after I closed and reopened multiple projects quickly one after another and Eclipse tried to rebuild them at the same time.
In my case Eclipse lost .location
file in the workspace directory for 2 out of 5 projects: <workspace>/.metadata/.plugins/org.eclipse.core.resources/.projects/<project name>/.location
I've followed instructions on How to get project list if delete .metadata accidentally and imported the project in the workspace manually via File :: Import :: Other :: General :: Existing Projects
. After that .location
file was created again and Eclipse stopped complaining.
Use this:
strstr('filename.ext','.',true);
//result filename
The @Devart's version is correct, but here are some improvements to avoid having error. I've edited the @Devart's answer, but it was not accepted.
SET FOREIGN_KEY_CHECKS = 0;
SET GROUP_CONCAT_MAX_LEN=32768;
SET @tables = NULL;
SELECT GROUP_CONCAT('`', table_name, '`') INTO @tables
FROM information_schema.tables
WHERE table_schema = (SELECT DATABASE());
SELECT IFNULL(@tables,'dummy') INTO @tables;
SET @tables = CONCAT('DROP TABLE IF EXISTS ', @tables);
PREPARE stmt FROM @tables;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;
SET FOREIGN_KEY_CHECKS = 1;
This script will not raise error with NULL result in case when you already deleted all tables in the database by adding at least one nonexistent - "dummy" table.
And it fixed in case when you have many tables.
And This small change to drop all view exist in the Database
SET FOREIGN_KEY_CHECKS = 0;
SET GROUP_CONCAT_MAX_LEN=32768;
SET @views = NULL;
SELECT GROUP_CONCAT('`', TABLE_NAME, '`') INTO @views
FROM information_schema.views
WHERE table_schema = (SELECT DATABASE());
SELECT IFNULL(@views,'dummy') INTO @views;
SET @views = CONCAT('DROP VIEW IF EXISTS ', @views);
PREPARE stmt FROM @views;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;
SET FOREIGN_KEY_CHECKS = 1;
It assumes that you run the script from Database you want to delete. Or run this before:
USE REPLACE_WITH_DATABASE_NAME_YOU_WANT_TO_DELETE;
Thank you to Steve Horvath to discover the issue with backticks.
You can either return a response as String
as suggested by @vagaasen or you can use ResponseEntity
Object provided by Spring as below. By this way you can also return Http status code
which is more helpful in webservice call.
@RestController
@RequestMapping("/api")
public class MyRestController
{
@GetMapping(path = "/hello", produces=MediaType.APPLICATION_JSON_VALUE)
public ResponseEntity<Object> sayHello()
{
//Get data from service layer into entityList.
List<JSONObject> entities = new ArrayList<JSONObject>();
for (Entity n : entityList) {
JSONObject entity = new JSONObject();
entity.put("aa", "bb");
entities.add(entity);
}
return new ResponseEntity<Object>(entities, HttpStatus.OK);
}
}
As @gfullam stated in a comment to @BoffinbraiN's answer, the <dir>
you are deleting itself might not be the one which contains files: there might be subdirectories in <dir>
that get a "The directory is not empty" message and the only solution then would be to recursively iterate over the directories, manually deleting all their containing files... I ended up deciding to use a port of rm
from UNIX. rm.exe
comes with Git Bash, MinGW, Cygwin, GnuWin32 and others. You just need to have its parent directory in your PATH and then execute as you would in a UNIX system.
Batch script example:
set PATH=C:\cygwin64\bin;%PATH%
rm -rf "C:\<dir>"
I like this if you want to get just some parts of the query:
new CriteriaQueryTranslator(
factory,
executableCriteria,
executableCriteria.getEntityOrClassName(),
CriteriaQueryTranslator.ROOT_SQL_ALIAS)
.getWhereCondition();
For instance something like this:
String where = new CriteriaQueryTranslator(
factory,
executableCriteria,
executableCriteria.getEntityOrClassName(),
CriteriaQueryTranslator.ROOT_SQL_ALIAS)
.getWhereCondition();
String sql = "update my_table this_ set this_.status = 0 where " + where;
Here is a solution that will work with list or dict type arguments without whining:
def memoize(fn):
"""returns a memoized version of any function that can be called
with the same list of arguments.
Usage: foo = memoize(foo)"""
def handle_item(x):
if isinstance(x, dict):
return make_tuple(sorted(x.items()))
elif hasattr(x, '__iter__'):
return make_tuple(x)
else:
return x
def make_tuple(L):
return tuple(handle_item(x) for x in L)
def foo(*args, **kwargs):
items_cache = make_tuple(sorted(kwargs.items()))
args_cache = make_tuple(args)
if (args_cache, items_cache) not in foo.past_calls:
foo.past_calls[(args_cache, items_cache)] = fn(*args,**kwargs)
return foo.past_calls[(args_cache, items_cache)]
foo.past_calls = {}
foo.__name__ = 'memoized_' + fn.__name__
return foo
Note that this approach can be naturally extended to any object by implementing your own hash function as a special case in handle_item. For example, to make this approach work for a function that takes a set as an input argument, you could add to handle_item:
if is_instance(x, set):
return make_tuple(sorted(list(x)))
Like this:
import java.util.*;
Set<Integer> a = new HashSet<Integer>();
a.add( 1);
a.add( 2);
a.add( 3);
Or adding from an Array/ or multiple literals; wrap to a list, first.
Integer[] array = new Integer[]{ 1, 4, 5};
Set<Integer> b = new HashSet<Integer>();
b.addAll( Arrays.asList( b)); // from an array variable
b.addAll( Arrays.asList( 8, 9, 10)); // from literals
To get the intersection:
// copies all from A; then removes those not in B.
Set<Integer> r = new HashSet( a);
r.retainAll( b);
// and print; r.toString() implied.
System.out.println("A intersect B="+r);

The problem is that you are trying to access a collection in an object that is detached. You need to re-attach the object before accessing the collection to the current session. You can do that through
session.update(object);
Using lazy=false
is not a good solution because you are throwing away the Lazy Initialization feature of hibernate. When lazy=false
, the collection is loaded in memory at the same time that the object is requested. This means that if we have a collection with 1000 items, they all will be loaded in memory, despite we are going to access them or not. And this is not good.
Please read this article where it explains the problem, the possible solutions and why is implemented this way. Also, to understand Sessions and Transactions you must read this other article.

You can add functionality to an Array by extending its prototype
object.
Array.prototype.nullify = function( n ) {
n = n >>> 0;
for( var i = 0; i < n; ++i ) {
this[ i ] = null;
}
return this;
};
Then:
var arr = [].nullify(9);
or:
var arr = [].nullify(9).map(function() { return [].nullify(9); });
@Bruno Lavit has a great answer, but if you want you can just access the log and download it as txt file to your workspace from the job's URL:
${BUILD_URL}/consoleText
Then it's only a matter of downloading this page to your ${Workspace}
Invoke ANT
" and use the GET targetGood luck!
Edit:
The actual log file on the file system is not on the slave, but kept in the Master machine. You can find it under: $JENKINS_HOME/jobs/$JOB_NAME/builds/lastSuccessfulBuild/log
If you're looking for another build just replace lastSuccessfulBuild
with the build you're looking for.
Simply check if there is a protocol (delineated by "://") and add "http://" if there isn't.
if (false === strpos($url, '://')) {
$url = 'http://' . $url;
}
Note: This may be a simple and straightforward solution, but Jack's answer using parse_url
is almost as simple and much more robust. You should probably use that one.
For a null-safe copy of an array, you can also use an optional with the Object.clone()
method provided in this answer.
int[] arrayToCopy = {1, 2, 3};
int[] copiedArray = Optional.ofNullable(arrayToCopy).map(int[]::clone).orElse(null);
Put your script in a file foo.py
starting with
#!/usr/bin/python
Then give execute permission to that script using
chmod a+x foo.py
and use the full path of your foo.py
file in your crontab

See documentation of execve(2) which is handling the shebang.
To avoid the focus advancing to the next editable field (if you have one) you might want to ignore the key-down events, but handle key-up events. I also prefer to filter first on the keyCode, assuming that it would be marginally more efficient. By the way, remember that returning true means that you have handled the event, so no other listener will. Anyway, here is my version.
ETFind.setOnKeyListener(new OnKeyListener()
{
public boolean onKey(View v, int keyCode, KeyEvent event)
{
if (keyCode == KeyEvent.KEYCODE_DPAD_CENTER
|| keyCode == KeyEvent.KEYCODE_ENTER) {
if (event.getAction() == KeyEvent.ACTION_DOWN) {
// do nothing yet
} else if (event.getAction() == KeyEvent.ACTION_UP) {
findForward();
} // is there any other option here?...
// Regardless of what we did above,
// we do not want to propagate the Enter key up
// since it was our task to handle it.
return true;
} else {
// it is not an Enter key - let others handle the event
return false;
}
}
});
string input = "this is a test";
string[] afterSplit = input.Split();
foreach (var word in afterSplit)
Console.WriteLine(word);
Result:
this
is
a
test
This code works for me:
Sub test()
Dim myRange As Range
Dim NumRows As Integer
Set myRange = Range("A:A")
NumRows = Application.WorksheetFunction.CountA(myRange)
MsgBox NumRows
End Sub
That's because someone else is accessing the database. Put the database into single user mode then rename it.

It depends on whether you have installed Git Bash in the current user only or all users:
If it is installed on all users then put "terminal.integrated.shell.windows": "C:\\Program Files\\Git\\bin\\bash.exe"
in your User Settings (Ctrl + Comma).
If it is installed on only the current user then put "terminal.integrated.shell.windows": "C:\\Users\\<name of your user>\\AppData\\Local\\Programs\\Git\\bin\\bash.exe"
in your User Settings (Ctrl + Comma).
If the methods listed above do not work then you should try Christer's solution which says -
If you want the integrated environment you need to point to the
sh.exe
file inside thebin
folder of your Git installation.So the configuration should say
C:\\<my-git-install>\\bin\\sh.exe
.
Note: The sh.exe and bash.exe appear completely same to me. There should be no difference between them.
@IanDevlin is correct. MDN's rules say the following:
"The HTML Header Element "" defines a page header — typically containing the logo and name of the site and possibly a horizontal menu..."
The word "possibly" there is key. It goes on to say that the header doesn't necessarily need to be a site header. For instance you could include a "header" on a pop-up modal or on other modular parts of the document where there is a header and it would be helpful for a user on a screen reader to know about it.
It terms of the implicit use of NAV you can use it anywhere there is grouped site navigation, although it's usually omitted from the "footer" section for mini-navs / important site links.
Really it comes down to personal / team choice. Decide what you and your team feel is more semantic and more important and the try to be consistent. For me, if the nav is inline with the logo and the main site's "h1" then it makes sense to put it in the "header" but if you have a different design choice then decide on a case by case basis.
Most importantly check out the docs and be sure if you choose to omit or include you understand why you are making that particular decision.
I needed something exactly as this (in a little more complex environment and the solution with a lot of 'mouseenters' and 'mouseleaves' wasnt working properly) so i created a little jquery plugin that adds the method ismouseover. It has worked pretty well so far.
//jQuery ismouseover method
(function($){
$.mlp = {x:0,y:0}; // Mouse Last Position
function documentHandler(){
var $current = this === document ? $(this) : $(this).contents();
$current.mousemove(function(e){jQuery.mlp = {x:e.pageX,y:e.pageY}});
$current.find("iframe").load(documentHandler);
}
$(documentHandler);
$.fn.ismouseover = function(overThis) {
var result = false;
this.eq(0).each(function() {
var $current = $(this).is("iframe") ? $(this).contents().find("body") : $(this);
var offset = $current.offset();
result = offset.left<=$.mlp.x && offset.left + $current.outerWidth() > $.mlp.x &&
offset.top<=$.mlp.y && offset.top + $current.outerHeight() > $.mlp.y;
});
return result;
};
})(jQuery);
Then in any place of the document yo call it like this and it returns true or false:
$("#player").ismouseover()
I tested it on IE7+, Chrome 1+ and Firefox 4 and is working properly.
If you really need to have ADB
running as root
, the quickest and easiest way is to install Android Custom ROMs and the most popular is CyanogenMod
for it has the Root Access
options in developer options menu where you can choose to give root access to apps and ADB
. I used CM before but since it wasn't developed anymore, I tried looking for some solutions out there. Although CyanogenMod is still a good alternative because it does not have bloatware.
One alternative I found out from a friend is using adbd insecure
app which you could try from here: https://forum.xda-developers.com/showthread.php?t=1687590. In my case, it works perferct with an Android custom kernel, but not with the Android stock ROM (vanilla android only). You may try other alternatives too like modifying boot.img
of the Android ROM.
Basically, ajax request as well as synchronous request sends your document cookies automatically. So, you need to set your cookie to document, not to request. However, your request is cross-domain, and things became more complicated. Basing on this answer, additionally to set document cookie, you should allow its sending to cross-domain environment:
type: "GET",
url: "http://example.com",
cache: false,
// NO setCookies option available, set cookie to document
//setCookies: "lkfh89asdhjahska7al446dfg5kgfbfgdhfdbfgcvbcbc dfskljvdfhpl",
crossDomain: true,
dataType: 'json',
xhrFields: {
withCredentials: true
},
success: function (data) {
alert(data);
});
I think you should use reflection. Something like this:
private T ConvertDictionaryTo<T>(IDictionary<string, object> dictionary) where T : new()
{
Type type = typeof (T);
T ret = new T();
foreach (var keyValue in dictionary)
{
type.GetProperty(keyValue.Key).SetValue(ret, keyValue.Value, null);
}
return ret;
}
It takes your dictionary and loops through it and sets the values. You should make it better but it's a start. You should call it like this:
SomeClass someClass = ConvertDictionaryTo<SomeClass>(a);
The "official" way to get the vs2015 is to go to https://my.visualstudio.com/ ; join the " Visual Studio Dev Essentials" and then search the relevant file to download https://my.visualstudio.com/Downloads?q=Visual%20Studio%202015%20with%20Update%203
@liquide's answer works great.
System.IO.File.Copy(inputFilePath, printerPath);
Which I found from the Zebra's ZPL Programmer's Guide Volume 1 (2005)
Use get_the_category()
like this:
<?php
foreach((get_the_category()) as $category) {
echo $category->cat_name . ' ';
}
?>
It returns a list because a post can have more than one category.
The documentation also explains how to do this from outside the loop.
Bootstrap 4.0 gives an option to modify modal data using jquery: https://getbootstrap.com/docs/4.0/components/modal/#varying-modal-content
Here is the script tag on the docs :
$('#exampleModal').on('show.bs.modal', function (event) {
var button = $(event.relatedTarget) // Button that triggered the modal
var recipient = button.data('whatever') // Extract info from data-* attributes
// If necessary, you could initiate an AJAX request here (and then do the updating in a callback).
// Update the modal's content. We'll use jQuery here, but you could use a data binding library or other methods instead.
var modal = $(this)
modal.find('.modal-title').text('New message to ' + recipient)
modal.find('.modal-body input').val(recipient)
})
It works for the most part. Only call to modal was not working. Here is a modification on the script that works for me:
$(document).on('show.bs.modal', '#exampleModal',function(event){
... // same as in above script
})
go 1.13

I've faced such an issue and dig tones of material. So, to avoid ugly iteration you can simply tune your hql:
You need to frame your query like this
select entity from Entity as entity where ...
Also check such case, it perfectly works for me:
public List<User> findByRole(String role) {
Query query = sessionFactory.getCurrentSession().createQuery("select user from User user join user.userRoles where role_name=:role_name");
query.setString("role_name", role);
@SuppressWarnings("unchecked")
List<User> users = (List<User>) query.list();
return users;
}
So here we are extracting object from query, not a bunch of fields. Also it's looks much more pretty.
Most modern desktop browsers such as Chrome, Mozilla and Internet Explorer support images encoded as data URL. But there are problems displaying data URLs in some mobile browsers: Android Stock Browser and Dolphin Browser won't display embedded JPEGs.
I reccomend you to use the following tools for online base64 encoding/decoding:
Check the "Format as Data URL" option to format as a Data URL.

It seems like these would be good to have because (I assume) if you could specify the number you're typing in is a short then java wouldn't have to cast it
Since the parsing of literals happens at compile time, this is absolutely irrelevant in regard to performance. The only reason having short
and byte
suffixes would be nice is that it lead to more compact code.
In v2.0 of the Graph API, calling /me/friends
returns the person's friends who also use the app.
In addition, in v2.0, you must request the user_friends
permission from each user. user_friends
is no longer included by default in every login. Each user must grant the user_friends
permission in order to appear in the response to /me/friends
. See the Facebook upgrade guide for more detailed information, or review the summary below.
The /me/friendlists
endpoint and user_friendlists
permission are not what you're after. This endpoint does not return the users friends - its lets you access the lists a person has made to organize their friends. It does not return the friends in each of these lists. This API and permission is useful to allow you to render a custom privacy selector when giving people the opportunity to publish back to Facebook.
If you want to access a list of non-app-using friends, there are two options:
If you want to let your people tag their friends in stories that they publish to Facebook using your App, you can use the /me/taggable_friends
API. Use of this endpoint requires review by Facebook and should only be used for the case where you're rendering a list of friends in order to let the user tag them in a post.
If your App is a Game AND your Game supports Facebook Canvas, you can use the /me/invitable_friends
endpoint in order to render a custom invite dialog, then pass the tokens returned by this API to the standard Requests Dialog.
In other cases, apps are no longer able to retrieve the full list of a user's friends (only those friends who have specifically authorized your app using the user_friends
permission).
For apps wanting allow people to invite friends to use an app, you can still use the Send Dialog on Web or the new Message Dialog on iOS and Android.
As an addon to Dima V's answer this is what I did to make this work for me.
// First declare the window global outside the class
declare let window: any;
// Inside the required class method
let globVarName = window.globVarName;
This will actually be the correct answer:
function scrolled(event) {
const container = event.target.body
const {clientHeight, scrollHeight, scrollY: scrollTop} = container
if (clientHeight + scrollY >= scrollHeight) {
scrolledToBottom(event);
}
}
The reason for using the event
is up-to-date data, if you'll use a direct reference to the div you'll get outdated scrollY
and will fail to detect the position correctly.
additional way is to wrap it in a setTimeout
and wait till the data updates.
You can read the manpage for proc for more detail, but in summary you can read /proc/[number]/stat to get the information about a process. This is also used by the 'ps' command.
All the fields and their scanf format specifiers are documented in the proc manpage.
Here are some of the information from the manpage copied (it is quite long):
pid %d The process ID.
comm %s
The filename of the executable, in parentheses. This is
visible whether or not the executable is swapped out.
state %c
One character from the string "RSDZTW" where R is runâ
ning, S is sleeping in an interruptible wait, D is waitâ
ing in uninterruptible disk sleep, Z is zombie, T is
traced or stopped (on a signal), and W is paging.
ppid %d
The PID of the parent.
pgrp %d
The process group ID of the process.
session %d
The session ID of the process.
tty_nr %d
The tty the process uses.
tpgid %d
The process group ID of the process which currently owns
the tty that the process is connected to.
For anyone else finding this - its worth noting that you can set the key value in the input name. Thanks to the answer in POSTing Form Fields with same Name Attribute you also can interplay strings or integers without quoting.
The answers assume that you don't mind the key value coming back for PHP however you can set name=[yourval]
(string or int) which then allows you to refer to an existing record.
On Windows, there are two differences between mutexes and binary semaphores:
A mutex can only be released by the thread which has ownership, i.e. the thread which previously called the Wait function, (or which took ownership when creating it). A semaphore can be released by any thread.
A thread can call a wait function repeatedly on a mutex without blocking. However, if you call a wait function twice on a binary semaphore without releasing the semaphore in between, the thread will block.
You should consider replacing your line breaks with <br/>
. In HTML a line break will only stand for new line in your code.
Alternatively you can use some other HTML markups like placing your lines in paragraphs:
<p>Sample line</p>
<p>Another line</p>
or other wrappers like for instance <div>sample</div>
with CSS attribute: display: block
.
You can also use <pre>
. The content of pre
will have its HTML styling ignored. In other words it will display pure HTML with normal \n
line breaks.

Here is implementation of standard C++ 14 using vectors and tuples to Read and Write Text,Binary and Hex files
.
Snippet code :
try {
if (file_type == BINARY_FILE) {
/*Open the stream in binary mode.*/
std::ifstream bin_file(file_name, std::ios::binary);
if (bin_file.good()) {
/*Read Binary data using streambuffer iterators.*/
std::vector<uint8_t> v_buf((std::istreambuf_iterator<char>(bin_file)), (std::istreambuf_iterator<char>()));
vec_buf = v_buf;
bin_file.close();
}
else {
throw std::exception();
}
}
else if (file_type == ASCII_FILE) {
/*Open the stream in default mode.*/
std::ifstream ascii_file(file_name);
string ascii_data;
if (ascii_file.good()) {
/*Read ASCII data using getline*/
while (getline(ascii_file, ascii_data))
str_buf += ascii_data + "\n";
ascii_file.close();
}
else {
throw std::exception();
}

You may want to try:
for (int i=0; i < 2; i++)
{
Toast.makeText(this, "blah", Toast.LENGTH_LONG).show();
}
to double the time. If you specify 3 instead the 2 it will triple the time..etc.
I agree with everyone else here: With JS on the client, the cat is out of the bag and there is nothing completely foolproof that can be done.
Having said that; in some cases I do this to put some hurdles in the way of those who want to take a look at the code. This is how the algorithm works (roughly)
The server creates 3 hashed and salted values. One for the current timestamp, and the other two for each of the next 2 seconds. These values are sent over to the client via Ajax to the client as a comma delimited string; from my PHP module. In some cases, I think you can hard-bake these values into a script section of HTML when the page is formed, and delete that script tag once the use of the hashes is over The server is CORS protected and does all the usual SERVER_NAME etc check (which is not much of a protection but at least provides some modicum of resistance to script kiddies).
Also it would be nice, if the the server checks if there was indeed an authenticated user's client doing this
The client then sends the same 3 hashed values back to the server thru an ajax call to fetch the actual JS that I need. The server checks the hashes against the current time stamp there... The three values ensure that the data is being sent within the 3 second window to account for latency between the browser and the server
The server needs to be convinced that one of the hashes is matched correctly; and if so it would send over the crucial JS back to the client. This is a simple, crude "One time use Password" without the need for any database at the back end.
This means, that any hacker has only the 3 second window period since the generation of the first set of hashes to get to the actual JS code.
The entire client code can be inside an IIFE function so some of the variables inside the client are even more harder to read from the Inspector console
This is not any deep solution: A determined hacker can register, get an account and then ask the server to generate the first three hashes; by doing tricks to go around Ajax and CORS; and then make the client perform the second call to get to the actual code -- but it is a reasonable amount of work.
Moreover, if the Salt used by the server is based on the login credentials; the server may be able to detect who is that user who tried to retreive the sensitive JS (The server needs to do some more additional work regarding the behaviour of the user AFTER the sensitive JS was retreived, and block the person if the person, say for example, did not do some other activity which was expected)
An old, crude version of this was done for a hackathon here: http://planwithin.com/demo/tadr.html That wil not work in case the server detects too much latency, and it goes beyond the 3 second window period
To fix the indentation and formatting in all files of your solution:
2
);This will recursively open and save all files in your solution, setting the indentation you defined above.
You might want to check other programming languages tabs (Options...) for Code Style > Formatting as well.
if you want to deal with base_2 only then i recommend using left shift operator << instead of math library.
sample code :
int exp = 16;
for(int base_2 = 1; base_2 < (1 << exp); (base_2 <<= 1)){
std::cout << base_2 << std::endl;
}
sample output :
1 2 4 8 16 32 64 128 256 512 1024 2048 4096 8192 16384 32768
The best way is to use fixtures.
Note: Keep in mind that fixtures do direct inserts and don't use your model so if you have callbacks that populate data you will need to find a workaround.
This must work!
client (angular):
$scope.saveForm = function () {
var formData = new FormData();
var file = $scope.myFile;
var json = $scope.myJson;
formData.append("file", file);
formData.append("ad",JSON.stringify(json));//important: convert to JSON!
var req = {
url: '/upload',
method: 'POST',
headers: {'Content-Type': undefined},
data: formData,
transformRequest: function (data, headersGetterFunction) {
return data;
}
};
Backend-Spring Boot:
@RequestMapping(value = "/upload", method = RequestMethod.POST)
public @ResponseBody
Advertisement storeAd(@RequestPart("ad") String adString, @RequestPart("file") MultipartFile file) throws IOException {
Advertisement jsonAd = new ObjectMapper().readValue(adString, Advertisement.class);
//do whatever you want with your file and jsonAd
When you want to destroy a session completely, you need to do more then just
session_destroy();
First, you should unset any session variables. Then you should destroy the session followed by closing the write of the session. This can be done by the following:
<?php
session_start();
unset($_SESSION);
session_destroy();
session_write_close();
header('Location: /');
die;
?>
The reason you want have a separate script for a logout is so that you do not accidently execute it on the page. So make a link to your logout script, then the header will redirect to the root of your site.
Edit:
You need to remove the () from your exit code near the top of your script. it should just be
exit;
You might also try
Application.CalculateFull
or
Application.CalculateFullRebuild
if you don't mind rebuilding all open workbooks, rather than just the active worksheet. (CalculateFullRebuild
rebuilds dependencies as well.)
If you are using the TestCaseSource
attribute, ensure the source exists and respects the documentation, otherwise your tests will not be discovered.
....but $('span', $('#foo')); doesn't work?
This method is called as providing selector context.
In this you provide a second argument to the jQuery selector. It can be any css object string just like you would pass for direct selecting or a jQuery element.
eg.
$("span",".cont1").css("background", '#F00');
The above line will select all spans within the container having the class named cont1
.
Cant you just use String.replace(" ", "");
What about:
.close-image{
display:block;
cursor:pointer;
z-index:3;
position:absolute;
top:0;
right:0;
}
Is that the desired result?
If bringing existing Visual Studio 2015 solution into Visual Studio 2017 and you want to build it with c++17 native compiler, you should first Retarget the solution/projects to v141 , THEN the dropdown will appear as described above ( Configuration Properties -> C/C++ -> Language -> Language Standard)
This solution provides a strict FixedLengthArray (ak.a. SealedArray) type signature based in Tuples.
Syntax example :
// Array containing 3 strings
let foo : FixedLengthArray<[string, string, string]>
This is the safest approach, considering it prevents accessing indexes out of the boundaries.
Implementation :
type ArrayLengthMutationKeys = 'splice' | 'push' | 'pop' | 'shift' | 'unshift' | number
type ArrayItems<T extends Array<any>> = T extends Array<infer TItems> ? TItems : never
type FixedLengthArray<T extends any[]> =
Pick<T, Exclude<keyof T, ArrayLengthMutationKeys>>
& { [Symbol.iterator]: () => IterableIterator< ArrayItems<T> > }
Tests :
var myFixedLengthArray: FixedLengthArray< [string, string, string]>
// Array declaration tests
myFixedLengthArray = [ 'a', 'b', 'c' ] // ? OK
myFixedLengthArray = [ 'a', 'b', 123 ] // ? TYPE ERROR
myFixedLengthArray = [ 'a' ] // ? LENGTH ERROR
myFixedLengthArray = [ 'a', 'b' ] // ? LENGTH ERROR
// Index assignment tests
myFixedLengthArray[1] = 'foo' // ? OK
myFixedLengthArray[1000] = 'foo' // ? INVALID INDEX ERROR
// Methods that mutate array length
myFixedLengthArray.push('foo') // ? MISSING METHOD ERROR
myFixedLengthArray.pop() // ? MISSING METHOD ERROR
// Direct length manipulation
myFixedLengthArray.length = 123 // ? READ-ONLY ERROR
// Destructuring
var [ a ] = myFixedLengthArray // ? OK
var [ a, b ] = myFixedLengthArray // ? OK
var [ a, b, c ] = myFixedLengthArray // ? OK
var [ a, b, c, d ] = myFixedLengthArray // ? INVALID INDEX ERROR
(*) This solution requires the noImplicitAny
typescript configuration directive to be enabled in order to work (commonly recommended practice)
This solution behaves as an augmentation of the Array
type, accepting an additional second parameter(Array length). Is not as strict and safe as the Tuple based solution.
Syntax example :
let foo: FixedLengthArray<string, 3>
Keep in mind that this approach will not prevent you from accessing an index out of the declared boundaries and set a value on it.
Implementation :
type ArrayLengthMutationKeys = 'splice' | 'push' | 'pop' | 'shift' | 'unshift'
type FixedLengthArray<T, L extends number, TObj = [T, ...Array<T>]> =
Pick<TObj, Exclude<keyof TObj, ArrayLengthMutationKeys>>
& {
readonly length: L
[ I : number ] : T
[Symbol.iterator]: () => IterableIterator<T>
}
Tests :
var myFixedLengthArray: FixedLengthArray<string,3>
// Array declaration tests
myFixedLengthArray = [ 'a', 'b', 'c' ] // ? OK
myFixedLengthArray = [ 'a', 'b', 123 ] // ? TYPE ERROR
myFixedLengthArray = [ 'a' ] // ? LENGTH ERROR
myFixedLengthArray = [ 'a', 'b' ] // ? LENGTH ERROR
// Index assignment tests
myFixedLengthArray[1] = 'foo' // ? OK
myFixedLengthArray[1000] = 'foo' // ? SHOULD FAIL
// Methods that mutate array length
myFixedLengthArray.push('foo') // ? MISSING METHOD ERROR
myFixedLengthArray.pop() // ? MISSING METHOD ERROR
// Direct length manipulation
myFixedLengthArray.length = 123 // ? READ-ONLY ERROR
// Destructuring
var [ a ] = myFixedLengthArray // ? OK
var [ a, b ] = myFixedLengthArray // ? OK
var [ a, b, c ] = myFixedLengthArray // ? OK
var [ a, b, c, d ] = myFixedLengthArray // ? SHOULD FAIL
Recommend to use LINQPad related nuget
package, then you can use exceptionInstance.Dump()
.
LINQPad.Runtime
LINQPad
Sample code:
using System;
using LINQPad;
namespace csharp_Dump_test
{
public class Program
{
public static void Main()
{
try
{
dosome();
}
catch (Exception ex)
{
ex.Dump();
}
}
private static void dosome()
{
throw new Exception("Unable.");
}
}
}
LinqPad nuget package is the most awesome tool for printing exception stack information. May it be helpful for you.
File size by MySQL type:
Is it possible to get this above example:
jQuery.fn.highlight = function (str, className)
{
var regex = new RegExp(str, "g");
return this.each(function ()
{
this.innerHTML = this.innerHTML.replace(
regex,
"<span class=\"" + className + "\">" + str + "</span>"
);
});
};
not to replace text inside html-tags like , this otherwise breakes the page.
I have found a way if you know startIndex and endIndex of the elements one need to remove from ArrayList
Let al
be the original ArrayList and startIndex
,endIndex
be start and end index to be removed from the array respectively:
al.subList(startIndex, endIndex + 1).clear();
For simple UTF-8 encoding, with slightly better compatibility than TextEncoder
, Blob does the trick. Won't work in very old browsers though.
new Blob([""]).size; // -> 4
For the record:
"Data at the root level is invalid" means that you have attempted to parse something that is not an XML document. It doesn't even start to look like an XML document. It usually means just what you found: you're parsing something like the string "C:\inetpub\wwwroot\mysite\officelist.xml".
Adding on to the list this is how I got it working.
I was trying to install CKAN 2.7.2 on CentOS 7 from source and kept coming up against this error. For me it was because SELinux was enabled. I didn't need to disable it. Instead, after reading https://www.endpoint.com/blog/2010/10/13/selinux-httpd-modwsgi-26-rhel-centos-5, I found that turning on httpd_can_network_connect fixed it:
setsebool -P httpd_can_network_connect on
From that page:
httpd_can_network_connect - Allows httpd to make network connections, including the local ones you'll be making to a database
In case you also need to check if nextProps.blog
is not undefined
; you can do that in a single if
statement, like this:
if (typeof nextProps.blog !== "undefined" && typeof nextProps.blog.content !== "undefined") {
//
}
And, when an undefined
, empty
or null
value is not expected; you can make it more concise:
if (nextProps.blog && nextProps.blog.content) {
//
}
I know this question is ancient and has an accepted answer, but I found a better solution to the problem. I am posting it here so I don't create a duplicate question, and the solution is still available to others.
Switch the order of the elements. Use the :before
pseudo-element for the content that should be underneath, and adjust margins to compensate. The margin cleanup can be messy, but the desired z-index
will be preserved.
I've tested this with IE8 and FF3.6 successfully.
The getcode() method (Added in python2.6) returns the HTTP status code that was sent with the response, or None if the URL is no HTTP URL.

first convert your array too JSON
while($query->fetch()){
$col[] = json_encode($row,JSON_UNESCAPED_UNICODE);
}
then vonvert back it to array
foreach($col as &$array){
$array = json_decode($array,true);
}
good luck
Simplest solution I have seen
var offset = $("#target-element").offset();
$('html, body').animate({
scrollTop: offset.top,
scrollLeft: offset.left
}, 1000);
The function var_export returns a string representation of a variable, so you could do this:
var_export($res, true);
The second argument tells the function to return the string instead of echoing it.
Assume that you've defined do_something as a function, and you'd like to perform it N times. Maybe you can try the following:
todos = [do_something] * N
for doit in todos:
doit()

If you want, you can deactivate this feature in your git core config using
git config core.autocrlf false
But it would be better to just get rid of the warnings using
git config core.autocrlf true
They changed the switch statement (from C/Java/C++) behavior for c#. I guess the reasoning was that people forgot about the fall through and errors were caused. One book I read said to use goto to simulate, but this doesn't sound like a good solution to me.
There is no installation required. Just add jQuery to your application folder and give a reference to the js file.
<script type="text/javascript" src="jQuery.js"></script>
if jQuery is in the same folder of your referenced file.
if you are in a virtual environment, just run this:
conda install jupyter
Do this:
Properties props = new Properties();
props.setProperty(Context.INITIAL_CONTEXT_FACTORY, "com.sun.enterprise.naming.SerialInitContextFactory");
Context initialContext = new InitialContext(props);
Also add this to the libraries of the project:
C:\installs\glassfish\glassfish-4.1\glassfish\lib\gf-client.jar
adjust path accordingly
The easiest way is:
File.WriteAllText(path, string.Empty)
However, I recommend you use FileStream
because the first solution can throw UnauthorizedAccessException
using(FileStream fs = File.Open(path,FileMode.OpenOrCreate, FileAccess.ReadWrite))
{
lock(fs)
{
fs.SetLength(0);
}
}
NOTE: In this example code we open a directory and search for PDF files with open and closed parenthesis in the name of the file. You can check and replace any character in the name you like or just specify a whole new name using replace functions.
There are other ways to work from this code to do more elaborate renames but my main intention was to show how to use File.Move to do a batch rename. This worked against 335 PDF files in 180 directories when I ran it on my laptop. This is spur of the moment code and there are more elaborate ways to do it.

using System.Collections.Generic;
using System.IO;

var dirnames = Directory.GetDirectories(@"C:\the full directory path of files to rename goes here");
int i = 0;
try
{
foreach (var dir in dirnames)
{
var fnames = Directory.GetFiles(dir, "*.pdf").Select(Path.GetFileName);
DirectoryInfo d = new DirectoryInfo(dir);
FileInfo[] finfo = d.GetFiles("*.pdf");
foreach (var f in fnames)
{
i++;
Console.WriteLine("The number of the file being renamed is: {0}", i);
if (!File.Exists(Path.Combine(dir, f.ToString().Replace("(", "").Replace(")", ""))))
{
File.Move(Path.Combine(dir, f), Path.Combine(dir, f.ToString().Replace("(", "").Replace(")", "")));
}
else
{
Console.WriteLine("The file you are attempting to rename already exists! The file path is {0}.", dir);
foreach (FileInfo fi in finfo)
{
Console.WriteLine("The file modify date is: {0} ", File.GetLastWriteTime(dir));
}
}
}
}

If you are using Java 8 Do it as below
import static java.lang.Math.toIntExact;
public class DateFormatSampleCode {

int longTointValue = toIntExact(longValue);
System.out.println(longTointValue);
}
}
You might be confusing compilation from execution. Python has no compilation step! :) As soon as you type python myprogram.py
the program runs and, in your case, tries to connect to an open port 5000, giving an error if no server program is listening there. It sounds like you are familiar with two-step languages, that require compilation to produce an executable — and thus you are confusing Python's runtime compilaint that “I can't find anyone listening on port 5000!” with a compile-time error. But, in fact, your Python code is fine; you just need to bring up a listener before running it!
This code will execute two commands.bat that exist in the path C:/folders/folder.

This answer is directed in large part at a comment made by @RafalDowgird:
"The minimum size of operations is int." - This would be very strange (what about architectures that efficiently support char/short operations?) Is this really in the C++ spec?
Keep in mind that the C++ standard has the all-important "as-if" rule. See section 1.8: Program Execution:
3) This provision is sometimes called the "as-if" rule, because an implementation is free to disregard any requirement of the Standard as long as the result is as if the requirement had been obeyed, as far as can be determined from the observable behavior of the program.
The compiler cannot set an int
to be 8 bits in size, even if it were the fastest, since the standard mandates a 16-bit minimum int
.
Therefore, in the case of a theoretical computer with super-fast 8-bit operations, the implicit promotion to int
for arithmetic could matter. However, for many operations, you cannot tell if the compiler actually did the operations in the precision of an int
and then converted to a char
to store in your variable, or if the operations were done in char all along.
For example, consider unsigned char = unsigned char + unsigned char + unsigned char
, where addition would overflow (let's assume a value of 200 for each). If you promoted to int
, you would get 600, which would then be implicitly down cast into an unsigned char
, which would wrap modulo 256, thus giving a final result of 88. If you did no such promotions,you'd have to wrap between the first two additions, which would reduce the problem from 200 + 200 + 200
to 144 + 200
, which is 344, which reduces to 88. In other words, the program does not know the difference, so the compiler is free to ignore the mandate to perform intermediate operations in int
if the operands have a lower ranking than int
.
This is true in general of addition, subtraction, and multiplication. It is not true in general for division or modulus.
One can simply use java.bean.ConstructorProperties annotation - it's much less verbose and Jackson also accepts it. For example :
import java.beans.ConstructorProperties;
@ConstructorProperties({"answer","closed","language","interface","operation"})
public DialogueOutput(String answer, boolean closed, String language, String anInterface, String operation) {
this.answer = answer;
this.closed = closed;
this.language = language;
this.anInterface = anInterface;
this.operation = operation;
}
Since git is a distributed VCS, your local repository contains all of the information. No downloading is necessary; you just need to extract the content you want from the repo at your fingertips.
If you haven't committed the deletion, just check out the files from your current commit:
git checkout HEAD <path>
If you have committed the deletion, you need to check out the files from a commit that has them. Presumably it would be the previous commit:
git checkout HEAD^ <path>
but if it's n
commits ago, use HEAD~n
, or simply fire up gitk
, find the SHA1 of the appropriate commit, and paste it in.
There is a get method in HashMap:
for (String keys : objectSet.keySet())
{
System.out.println(keys + ":"+ objectSet.get(keys));
}
a = [0,1,2,3,127,200,255]
print str.join("", ("%02x" % i for i in a))
prints
000102037fc8ff
(Also note that your code will fail for integers in the range from 10 to 15.)
Go to view and press "Switch to scale mode" which will adjust the virtual screen when you adjust the application.
If you're happy to use the Microsoft Reactive Extensions, then this can work nicely:
public class Foo
{
public delegate void MyEventHandler(object source, MessageEventArgs args);
public event MyEventHandler _event;
public string ReadLine()
{
return Observable
.FromEventPattern<MyEventHandler, MessageEventArgs>(
h => this._event += h,
h => this._event -= h)
.Select(ep => ep.EventArgs.Message)
.First();
}
public void SendLine(string message)
{
_event(this, new MessageEventArgs() { Message = message });
}
}
public class MessageEventArgs : EventArgs
{
public string Message;
}
I can use it like this:
var foo = new Foo();
ThreadPoolScheduler.Instance
.Schedule(
TimeSpan.FromSeconds(5.0),
() => foo.SendLine("Bar!"));
var resp = foo.ReadLine();
Console.WriteLine(resp);
I needed to call the SendLine
message on a different thread to avoid locking, but this code shows that it works as expected.
You could use %in%
like this:
df[, !(colnames(df) %in% c("x","bar","foo"))]
You can use the 'attributes' method:
@car.attributes = {:model => 'Sierra', :years => '1990', :looks => 'Sexy'}
Source: http://api.rubyonrails.org/classes/ActiveRecord/Base.html
attributes=(new_attributes, guard_protected_attributes = true) Allows you to set all the attributes at once by passing in a hash with keys matching the attribute names (which again matches the column names).
If guard_protected_attributes is true (the default), then sensitive attributes can be protected from this form of mass-assignment by using the attr_protected macro. Or you can alternatively specify which attributes can be accessed with the attr_accessible macro. Then all the attributes not included in that won’t be allowed to be mass-assigned.
class User < ActiveRecord::Base
attr_protected :is_admin
end
user = User.new
user.attributes = { :username => 'Phusion', :is_admin => true }
user.username # => "Phusion"
user.is_admin? # => false
user.send(:attributes=, { :username => 'Phusion', :is_admin => true }, false)
user.is_admin? # => true
Instead of doing file_put_contents(***WebSiteURL***...)
you need to use the server path to /cache/lang/file.php
(e.g. /home/content/site/folders/filename.php
).
You cannot open a file over HTTP
and expect it to be written. Instead you need to open it using the local path.

window.location.href wasn't working in Android. I cleared cache in Android Chrome and it works fine. Suggest trying this first before getting involved in various coding.
I found that the Windows Defender Antimalware is causing huge delays. Go to Update & Security -> Settings -> Windows Defender. Open the Defender and in the Settings selection, choose Exclusions and add the "devenv.exe' process. It worked for me
I'm not sure what your reasons are, and even if you could pull it off somehow with Reflection Emit (I' not sure that you can), it doesn't sound like a good idea. What is probably a better idea is to have some kind of Dictionary and you can wrap access to the dictionary through methods in your class. That way you can store the data from the database in this dictionary, and then retrieve them using those methods.

If you want to close tty for specific user with all the process, above command is the easiest. You can use:
killall -u user_name
You can use a combiation of LEFT
and CHARINDEX
to find the index of the first space, and then grab everything to the left of that.
SELECT LEFT(YourColumn, charindex(' ', YourColumn) - 1)
And in case any of your columns don't have a space in them:

If there is any tag with an id
(e.g., <div id="foo"
>), then you can simply append #foo
to the URL. Otherwise, you can't arbitrarily link to portions of a page.
Here's a complete example: <a href="http://example.com/page.html#foo">Jump to #foo on page.html</a>
Linking content on the same page example: <a href="#foo">Jump to #foo on same page</a>
It is called a URI fragment.

say the string you want to turn into a number is in the variable S
a=tonumber(S)
provided that there are numbers and only numbers in S
it will return a number,
but if there are any characters that are not numbers (except periods for floats)
it will return nil
First, a better usage to compute number of elements when the actual array declaration is in scope is:
sizeof array / sizeof array[0]
This way you don't repeat the type name, which of course could change in the declaration and make you end up with an incorrect length computation. This is a typical case of don't repeat yourself.
Second, as a minor point, please note that sizeof
is not a function, so the expression above doesn't need any parenthesis around the argument to sizeof
.
Third, C doesn't have references so your usage of &
in a declaration won't work.
I agree that the proper C solution is to pass the length (using the size_t
type) as a separate argument, and use sizeof
at the place the call is being made if the argument is a "real" array.
Note that often you work with memory returned by e.g. malloc()
, and in those cases you never have a "true" array to compute the size off of, so designing the function to use an element count is more flexible.
If you use IIS, I'd suggest trying IIS CORS module.
It's easy to configure and works for all types of controllers.
Here is an example of configuration:
<system.webServer>
<cors enabled="true" failUnlistedOrigins="true">
<add origin="*" />
<add origin="https://*.microsoft.com"
allowCredentials="true"
maxAge="120">
<allowHeaders allowAllRequestedHeaders="true">
<add header="header1" />
<add header="header2" />
</allowHeaders>
<allowMethods>
<add method="DELETE" />
</allowMethods>
<exposeHeaders>
<add header="header1" />
<add header="header2" />
</exposeHeaders>
</add>
<add origin="http://*" allowed="false" />
</cors>
</system.webServer>
Change this line:
mMyListView.setAdapter(new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1,
listItems));
to:
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1,
listItems)
mMyListView.setAdapter(adapter);
and after updating the value of a list item, call:
adapter.notifyDataSetChanged();
You can use Google guava as such:
ImmutableList<char> dirs = ImmutableList.of('+', '-', '*', '^');
This isn't possible - you need to carry out an UPDATE for each table individually.
WARNING: DUBIOUS, BUT IT'LL WORK (PROBABLY) SOLUTION FOLLOWS
Alternatively, you could dump the database via mysqldump and simply perform the search/replace on the resultant SQL file. (I'd recommend offlining anything that might touch the database whilst this is in progress, as well as using the --add-drop-table and --extended-insert flags.) However, you'd need to be sure that the search/replace text wasn't going to alter anything other than the data itself (i.e.: that the text you were going to swap out might not occur as a part of SQL syntax) and I'd really try doing the re-insert on an empty test database first.)
intrepidis' answer on this page using a background SVG in CSS has the advantage of scaling nicely to any size or aspect ratio, though the SVG uses <path>
s with a fill that doesn't scale so well.
I've just updated the SVG code to use <line>
instead of <path>
and added non-scaling-stroke
vector-effect to prevent the strokes scaling with the container:
<svg xmlns='http://www.w3.org/2000/svg' version='1.1' preserveAspectRatio='none' viewBox='0 0 100 100'>
<line x1='0' y1='0' x2='100' y2='100' stroke='black' vector-effect='non-scaling-stroke'/>
<line x1='0' y1='100' x2='100' y2='0' stroke='black' vector-effect='non-scaling-stroke'/>
</svg>
Here's that dropped into the CSS from the original answer (with HTML made resizable):
.diag {_x000D_

Info on MySQL's full text search. This is restricted to MyISAM tables, so may not be suitable if you wantto use a different table type.
http://dev.mysql.com/doc/refman/5.0/en/fulltext-search.html
Even if WHERE textcolumn LIKE "%SUBSTRING%"
is going to be slow, I think it is probably better to let the Database handle it rather than have PHP handle it. If it is possible to restrict searches by some other criteria (date range, user, etc) then you may find the substring search is OK (ish).
If you are searching for whole words, you could pull out all the individual words into a separate table and use that to restrict the substring search. (So when searching for "my search string" you look for the the longest word "search" only do the substring search on records containing the word "search")

I encountered the same question, I 've made the mistake because:
Name in (info.plist -->Bundle identifier
) is not the same as (target-->build settings -->packaging-->Product bundle identifier
). Just make the same, that solved the problem.
It might be easier for you to understand using Functionoids which are expressively neater and more powerful to use, see this excellent and highly recommended C++ FAQ lite, in particular, look at section 33.12 onwards, but nonetheless, read it from the start of that section to gain a grasp and understanding of it.
To answer your question:
typedef void (*foobar)() fubarfn;
void Fun(fubarfn& baz){
fubarfn = baz;
baz();
}
Edit:
&
means the reference address*
means the value of what's contained at the reference address, called de-referencingSo using the reference, example below, shows that we are passing in a parameter, and directly modify it.
void FunByRef(int& iPtr){
iPtr = 2;
}
int main(void){
// ...
int n;
FunByRef(n);
cout << n << endl; // n will have value of 2
}
My answer comes quite late because I'm a pretty new developer. This is what you can do:
Location.select(:name, :website, :city).find(row.id)
Btw, this is Rails 4
The three constants have similar functions nowadays, but different historical origins, and very occasionally you may be required to use one or the other.
You need to think back to the days of old manual typewriters to get the origins of this. There are two distinct actions needed to start a new line of text:
In computers, these two actions are represented by two different characters - carriage return is CR
, ASCII character 13, vbCr
; line feed is LF
, ASCII character 10, vbLf
. In the old days of teletypes and line printers, the printer needed to be sent these two characters -- traditionally in the sequence CRLF
-- to start a new line, and so the CRLF
combination -- vbCrLf
-- became a traditional line ending sequence, in some computing environments.
The problem was, of course, that it made just as much sense to only use one character to mark the line ending, and have the terminal or printer perform both the carriage return and line feed actions automatically. And so before you knew it, we had 3 different valid line endings: LF
alone (used in Unix and Macintoshes), CR
alone (apparently used in older Mac OSes) and the CRLF
combination (used in DOS, and hence in Windows). This in turn led to the complications of DOS / Windows programs having the option of opening files in text mode
, where any CRLF
pair read from the file was converted to a single CR
(and vice versa when writing).
So - to cut a (much too) long story short - there are historical reasons for the existence of the three separate line separators, which are now often irrelevant: and perhaps the best course of action in .NET is to use Environment.NewLine
which means someone else has decided for you which to use, and future portability issues should be reduced.
In your view
object.errors.each do |attr,msg|
if msg.is_a? String
if attr == :base
content_tag :li, msg
elsif msg[0] == "^"
content_tag :li, msg[1..-1]
else
content_tag :li, "#{object.class.human_attribute_name(attr)} #{msg}"
end
end
end
When you want to override the error message without the attribute name, simply prepend the message with ^ like so:
validates :last_name,
uniqueness: {
scope: [:first_name, :course_id, :user_id],
case_sensitive: false,
message: "^This student has already been registered."
}
Specifically, if you are dealing with a UserForm, then you might try the Repaint method. You might encounter an issue with DoEvents if you are using event triggers in your form. For instance, any keys pressed while a function is running will be sent by DoEvents The keyboard input will be processed before the screen is updated, so if you are changing cells on a spreadsheet by holding down one of the arrow keys on the keyboard, then the cell change event will keep firing before the main function finishes.
A UserForm will not be refreshed in some cases, because DoEvents will fire the events; however, Repaint will update the UserForm and the user will see the changes on the screen even when another event immediately follows the previous event.
In the UserForm code it is as simple as:
Me.Repaint
No, you cannot set them all in a single statement.
At the general case, you need at least three properties:
border-color: red green white blue;
border-style: solid dashed dotted solid;
border-width: 1px 2px 3px 4px;
However, that would be quite messy. It would be more readable and maintainable with four:
border-top: 1px solid #ff0;
border-right: 2px dashed #f0F;
border-bottom: 3px dotted #f00;
border-left: 5px solid #09f;
Right click the web application and select "properties"
There should be a 'Web' tab where http://localhost:XXXXX
is specified - change the port number there and this will modify the configuration to use your new port number.
I usually start at 10000 and increment by 1 for each web app, to attempt to steer well clear of other applications and port numbers.
NexusRex provided a very good solution for deleting with join from the same table.
If you do this:
DELETE FROM story_category
WHERE category_id NOT IN (
SELECT DISTINCT category.id AS cid FROM category
INNER JOIN story_category ON category_id=category.id
)
you are going to get an error.
But if you wrap the condition in one more select:
DELETE FROM story_category
WHERE category_id NOT IN (
SELECT cid FROM (
SELECT DISTINCT category.id AS cid FROM category
INNER JOIN story_category ON category_id=category.id
) AS c
)
it would do the right thing!!
Explanation: The query optimizer does a derived merge optimization for the first query (which causes it to fail with the error), but the second query doesn't qualify for the derived merge optimization. Hence the optimizer is forced to execute the subquery first.
For completeness here is the HTML Helper for DropDownListFor that adds enabled parameter, when false select is disabled. It keeps html attributes defined in markup, or it enables usage of html attributes in markup, it posts select value to server and usage is very clean and simple.
Here is the code for helper:
public static MvcHtmlString DropDownListFor<TModel, TProperty>(this HtmlHelper<TModel> html, Expression<Func<TModel, TProperty>> expression, IEnumerable<SelectListItem> selectList, object htmlAttributes, bool enabled)
{
if (enabled)
{
return SelectExtensions.DropDownListFor<TModel, TProperty>(html, expression, selectList, htmlAttributes);
}
var htmlAttributesAsDict = HtmlHelper.AnonymousObjectToHtmlAttributes(htmlAttributes);
htmlAttributesAsDict.Add("disabled", "disabled");
string selectClientId = html.ViewContext.ViewData.TemplateInfo.GetFullHtmlFieldId(ExpressionHelper.GetExpressionText(expression));
htmlAttributesAsDict.Add("id", selectClientId + "_disabled");
var hiddenFieldMarkup = html.HiddenFor<TModel, TProperty>(expression);
var selectMarkup = SelectExtensions.DropDownListFor<TModel, TProperty>(html, expression, selectList, htmlAttributesAsDict);
return MvcHtmlString.Create(selectMarkup.ToString() + Environment.NewLine + hiddenFieldMarkup.ToString());
}
and usage, goal is to disable select if there is just one item in options, markup:
@Html.DropDownListFor(m => m.SomeValue, Model.SomeList, new { @class = "some-class" }, Model.SomeList > 1)
And there is one even more elegant HTML Helper example, no post support for now (pretty straight forward job, just use HAP and add hidden input as root element sibling and swap id's):
public static MvcHtmlString Disable(this MvcHtmlString previous, bool disabled, bool disableChildren = false)
{
if (disabled)
{
var canBeDisabled = new HashSet<string> { "button", "command", "fieldset", "input", "keygen", "optgroup", "option", "select", "textarea" };
var doc = new HtmlDocument();
doc.LoadHtml(previous.ToString());
var rootElements = doc.DocumentNode.Descendants().Where(
hn => hn.NodeType == HtmlNodeType.Element &&
canBeDisabled.Contains(hn.Name.ToLower()) &&
(disableChildren || hn.ParentNode.NodeType == HtmlNodeType.Document));
foreach (var element in rootElements)
{
element.SetAttributeValue("disabled", "");
}
string html = doc.DocumentNode.OuterHtml;
return MvcHtmlString.Create(html);
}
return previous;
}
For example there is a model property bool AllInputsDisabled, when true all html inputs should be disabled:
@Html.TextBoxFor(m => m.Address, new { placeholder = "Enter address" }).Disable(Model.AllInputsDisabled)
@Html.DropDownListFor(m => m.DoYou, Model.YesNoList).Disable(Model.AllInputsDisabled)

According to this :
SmtpClient and its network of types are poorly designed, we strongly recommend you use https://github.com/jstedfast/MailKit and https://github.com/jstedfast/MimeKit instead.
Reference : https://docs.microsoft.com/en-us/dotnet/api/system.net.mail.smtpclient?view=netframework-4.8
It's better to use MailKit
to send emails :
var message = new MimeMessage ();
message.From.Add (new MailboxAddress ("Joey Tribbiani", "[email protected]"));
message.To.Add (new MailboxAddress ("Mrs. Chanandler Bong", "[email protected]"));
message.Subject = "How you doin'?";
message.Body = new TextPart ("plain") {
Text = @"Hey Chandler,
I just wanted to let you know that Monica and I were going to go play some paintball, you in?
-- Joey"
};
using (var client = new SmtpClient ()) {
// For demo-purposes, accept all SSL certificates (in case the server supports STARTTLS)
client.ServerCertificateValidationCallback = (s,c,h,e) => true;
client.Connect ("smtp.friends.com", 587, false);
// Note: only needed if the SMTP server requires authentication
client.Authenticate ("joey", "password");
client.Send (message);
client.Disconnect (true);
}
The original code works fine for reading and separating the csv file data but you need to change the data type from csv to text.
Perhaps I didn't see the answer, but this is how I do it.
You need to have change these values
"windowsAuthentication": true, // needs to be true
"anonymousAuthentication": false, // needs to be false
Startup.cs --> ConfigureServices(...)
services.AddSingleton<IHttpContextAccessor, HttpContextAccessor>();
MVC or Web Api Controller
private readonly IHttpContextAccessor _httpContextAccessor;
//constructor then
_httpContextAccessor = httpContextAccessor;
Controller method:
string userName = _httpContextAccessor.HttpContext.User.Identity.Name;
Result is userName e.g. = Domain\username
You need to manually create the bundle for a debug build.
Bundle debug build:
#React-Native 0.59
react-native bundle --dev false --platform android --entry-file index.js --bundle-output ./android/app/src/main/assets/index.android.bundle --assets-dest ./android/app/src/main/res
#React-Native 0.49.0+
react-native bundle --dev false --platform android --entry-file index.js --bundle-output ./android/app/build/intermediates/assets/debug/index.android.bundle --assets-dest ./android/app/build/intermediates/res/merged/debug
#React-Native 0-0.49.0
react-native bundle --dev false --platform android --entry-file index.android.js --bundle-output ./android/app/build/intermediates/assets/debug/index.android.bundle --assets-dest ./android/app/build/intermediates/res/merged/debug
Then to build the APK's after bundling:
$ cd android
#Create debug build:
$ ./gradlew assembleDebug
#Create release build:
$ ./gradlew assembleRelease #Generated `apk` will be located at `android/app/build/outputs/apk`
P.S. Another approach might be to modify gradle scripts.
by using prototype function we can replace easily by passing object with keys and values and replacable text
String.prototype.replaceAll=function(obj,keydata='key'){
const keys=keydata.split('key');
return Object.entries(obj).reduce((a,[key,val])=> a.replace(`${keys[0]}${key}${keys[1]}`,val),this)
}
const data='hids dv sdc sd ${yathin} ${ok}'
console.log(data.replaceAll({yathin:12,ok:'hi'},'${key}'))

The '
character in SQL is used for string constants. In this case it is used for ending the string constant and not for comment.
You have two options:
1. Share via ?Boot
function in App\Providers\AppServiceProvider
:
public function boot()
{
view()->share('key', 'value');
}
And access $key
variable in any view file.
Note
: Remember that you can't access current Session
, Auth
, Route
data here. This option is good only if you want to share static data. Suppose you want to share some data based on the current user , route, or any custom session variable you won't be able to do with this.
2. Use of a helper class:
Create a helper class anywhere in your application and register it in Alias array in app.php
file in config
folder.
'aliases' => [
...,
'Helper' => App\HelperClass\Helper::class,
],
and create Helper.php
in HelperClass folder within App folder:
namespace App\HelperClass;
class Helper
{
public static function Sample()
{
//Your Code Here
}
}
and access it anywhere like Helper::Sample()
.
You will not be restricted
here to use Auth
, Route
, Session
, or any other classes.

I managed to install php54w according to Simon's suggestion, but then my sites stopped working perhaps because of an incompatibility with php-mysql or some other module. Even frantically restoring the old situation was not amusing: for anyone in my own situation the sequence is:
sudo yum remove php54w
sudo yum remove php54w-common
sudo yum install php-common
sudo yum install php-mysql
sudo yum install php
It would be nice if someone submitted the full procedure to update all the php packet. That was my production server and my heart is still rapidly beating.
Old question but still relevant. I've generated a dictionary that gets the appropriate datetime format for each region, here is the helper class I generated:
https://github.com/anakic/ExcelDateTimeFormatHelper/blob/master/FormatHelper.cs
FWIW this is how I went about it:
I see many answer reporting for zip and rar the Media Types application/zip
and application/x-rar-compressed
, respectively.
While the former matching is correct, for the latter IANA reports here https://www.iana.org/assignments/media-types/application/vnd.rar that for rar application/x-rar-compressed
is a deprecated alias name and instead application/vnd.rar
is the official one.
So, right Media Types from IANA in 2020 are:
zip
: application/zip
rar
: application/vnd.rar
I had a similar problem on a raspberry pi.
The problem was that http requires SSL and so I needed to force it to use https to get around this requirement.
sudo pip install --upgrade pip --index-url=https://pypi.python.org/simple
or
sudo pip-3.2 --upgrade pip --index-url=https://pypi.python.org/simple/
What I have done is implement List having a internal instance with all the methods delegated.
public class ContactList implements List<Contact>, Serializable {
private static final long serialVersionUID = -1862666454644475565L;
private final List<Contact> list;
public ContactList() {
super();
this.list = new ArrayList<Contact>();
}
public ContactList(List<Contact> list) {
super();
//copy and order list
List<Contact>aux= new ArrayList(list);
Collections.sort(aux);
this.list = aux;
}
public void clear() {
list.clear();
}
public boolean contains(Object object) {
return list.contains(object);
}
After, I have implemented a new method "putOrdered" which insert in the proper position if the element doesn't exist or replace just in case it exist.
public void putOrdered(Contact contact) {
int index=Collections.binarySearch(this.list,contact);
if(index<0){
index= -(index+1);
list.add(index, contact);
}else{
list.set(index, contact);
}
}
If you want to allow repeated elements just implement addOrdered instead (or both).
public void addOrdered(Contact contact) {
int index=Collections.binarySearch(this.list,contact);
if(index<0){
index= -(index+1);
}
list.add(index, contact);
}
If you want to avoid inserts you can also throw and unsupported operation exception on "add" and "set" methods.
public boolean add(Contact object) {
throw new UnsupportedOperationException("Use putOrdered instead");
}
... and also You have to be careful with ListIterator methods because they could modify your internal list. In this case you can return a copy of the internal list or again throw an exception.
public ListIterator<Contact> listIterator() {
return (new ArrayList<Contact>(list)).listIterator();
}

=Sum(C:C)-Sum(C1:C5)
Sum everything then remove the sum of the values in the cells you don't want, no Volatile Offset's, Indirect's, or Array's needed.
Just for fun if you don't like that method you could also use:
=SUM($C$6:INDEX($C:$C,MATCH(9.99999999999999E+307,$C:$C))
The above formula will Sum only from C6 through the last cell in C:C where a match of a number is found. This is also non-volatile, but I believe more costly and sloppy. Just added it in case you'd prefer this anyways.
If you would like to do function like CountA for text using the last text value in a column you could use.
=COUNTIF(C6:INDEX($C:$C,MATCH(REPT("Z",255),$C:$C)),"T")
you could also use other combinations like:
=Sum($C$6:$C$65536)
or
=CountIF($C$6:$C$65536,"T")
The above would do what you ask in Excel 2003 and lower
=Sum($C$6:$C$1048576)
or
=CountIF($C$6:$C$1048576,"T")
Would both work for Excel 2007+
All above functions would simply ignore all the blank values under the last value.
Edit just 1st line: Main
.class
Class<?> c = Main.class;
String path = c.getResource(c.getSimpleName() + ".class").getPath().replace(c.getSimpleName() + ".class", "");
System.out.println(path);
Output:
/C:/Users/Test/bin/
Maybe bad style but works fine!

The Keep It Simple And Stupid(KISS) principle might be useful on this one. Its more faster and easier to check if both passwords match by doing the following:
<div ng-app="app" ng-controller="passwordCheck">
<form name="signUp" ng-submit="submitForm()" novalidate>
<input type="password" name="password" ng-model="password" required>
<input type="password" name="ConfirmPassword" ng-model="passwordconfirm" required>
<button type="submit"> Submit</button>
</form>
<hr>
<span>Do they match?</span> {{signUp.password.$viewValue == signUp.confirmPassword.$viewValue}}
</div>
And Before submitting the form, you can do this in your js
var app = angular.module("app", []);
app.controller("passwordCheck", function($scope) {
$scope.submitForm = function() {
if ($scope.signUp.$valid && $scope.signUp.password.$viewValue == $scope.signUp.confirmPassword.$viewValue) {
alert('Its a match!');
};
};
});
You can test it in JSfiddle as well.

Try to Clean and rebuild. It worked in my case.
I am using EF 4.0 and WPF and I had similar problem, and .... found the issue that solved it (at least for me) in a very simple way.
Because, like you, I thought it must be simple to update a field in a table (i.e. in your case: Contact) that is referenced to by a foreignkey from another table (i.e. in your case: ContactType).
However, the Error Message: ".... is part of the object's key information and cannot be modified." only appears when you try to update a Primary Key (which wasn't my intention at all).
Had a closer look at the XML code of my EntityModel and found it:
<EntityType Name="Contact">
<Key>
<PropertyRef Name="ID" />
<PropertyRef Name="contactTypeID" /> <!-- This second line caused my problem -->
</Key>
<Property Name="ID" Type="int" Nullable="false" />
...
...
</EntityType>
For some reason (maybe I made some foolish mistake within my database), when Visual Studio autogenerated for me the DataModel from my database, it added in that very table (Contact), where I wanted to update the field (ContactTypeID
) a second PropertyRef
(second line).
I just deleted that second PropertyRef
:
<PropertyRef Name="contactTypeID" />
in both, the store model and the conceptual model and .... issue was solved :-)
Hence, remains like:
<EntityType Name="Contact">
<Key>
<PropertyRef Name="ID" />
</Key>
<Property Name="ID" Type="int" Nullable="false" />
...
...
</EntityType>
Updates and Inserts are now running smoothly like a baby .... :-)
Hence, good idea to check the XML of the datamodel to verify that only your PK is listed as PropertyRef
. Worked for me ... :-)
Use this. Beware of i's larger than 9, as these will require a char array with more than 2 elements to avoid a buffer overrun.
char c[2];
int i=1;
sprintf(c, "%d", i);
I also struggled finding articles on how to just generate the token part. I never found one and wrote my own. So if it helps:
The things to do are:
Microsoft.Owin
Microsoft.Owin.Host.SystemWeb
Microsoft.Owin.Security.OAuth
Microsoft.AspNet.Identity.Owin
startup
classThen create a HTML and a JavaScript (index.js
) file with these contents:
var loginData = 'grant_type=password&[email protected]&password=test123';
var xmlhttp = new XMLHttpRequest();
xmlhttp.onreadystatechange = function () {
if (xmlhttp.readyState === 4 && xmlhttp.status === 200) {
alert(xmlhttp.responseText);
}
}
xmlhttp.open("POST", "/token", true);
xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
xmlhttp.send(loginData);
<!DOCTYPE html>
<html>
<head>
<title></title>
</head>
<body>
<script type="text/javascript" src="index.js"></script>
</body>
</html>
The OWIN startup
class should have this content:
using System;
using System.Security.Claims;
using Microsoft.Owin;
using Microsoft.Owin.Security.OAuth;
using OAuth20;
using Owin;
[assembly: OwinStartup(typeof(Startup))]
namespace OAuth20
{
public class Startup
{
public static OAuthAuthorizationServerOptions OAuthOptions { get; private set; }
public void Configuration(IAppBuilder app)
{
OAuthOptions = new OAuthAuthorizationServerOptions()
{
TokenEndpointPath = new PathString("/token"),
Provider = new OAuthAuthorizationServerProvider()
{
OnValidateClientAuthentication = async (context) =>
{
context.Validated();
},
OnGrantResourceOwnerCredentials = async (context) =>
{
if (context.UserName == "[email protected]" && context.Password == "test123")
{
ClaimsIdentity oAuthIdentity = new ClaimsIdentity(context.Options.AuthenticationType);
context.Validated(oAuthIdentity);
}
}
},
AllowInsecureHttp = true,
AccessTokenExpireTimeSpan = TimeSpan.FromDays(1)
};
app.UseOAuthBearerTokens(OAuthOptions);
}
}
}
Run your project. The token should be displayed in the pop-up.
The differences are covered at the PostgreSQL documentation for date/time types. Yes, the treatment of TIME
or TIMESTAMP
differs between one WITH TIME ZONE
or WITHOUT TIME ZONE
. It doesn't affect how the values are stored; it affects how they are interpreted.
The effects of time zones on these data types is covered specifically in the docs. The difference arises from what the system can reasonably know about the value:
With a time zone as part of the value, the value can be rendered as a local time in the client.
Without a time zone as part of the value, the obvious default time zone is UTC, so it is rendered for that time zone.
The behaviour differs depending on at least three factors:
WITH TIME ZONE
or WITHOUT TIME ZONE
) of the value.Here are examples covering the combinations of those factors:
foo=> SET TIMEZONE TO 'Japan';
SET
foo=> SELECT '2011-01-01 00:00:00'::TIMESTAMP;
timestamp
---------------------
2011-01-01 00:00:00
(1 row)
foo=> SELECT '2011-01-01 00:00:00'::TIMESTAMP WITH TIME ZONE;
timestamptz
------------------------

foo=> SET TIMEZONE TO 'Australia/Melbourne';

For NodeJS v12 and above, --experimental-json-modules
would do the trick, without any help from babel.
https://nodejs.org/docs/latest-v14.x/api/esm.html#esm_experimental_json_modules
But it is imported in commonjs form, so import { a, b } from 'c.json'
is not yet supported.
But you can do:
import c from 'c.json';
const { a, b } = c;
h2.text-left{
position:relative;
top:50%;
transform: translateY(-50%);
-webkit-transform: translateY(-50%);
-ms-transform: translateY(-50%);
}
Explanation:
The top:50% style essentially pushes the header element down 50% from the top of the parent element. The translateY stylings also act in a similar manner by moving then element down 50% from the top.
Please note that this works well for headers with 1 (maybe 2) lines of text as this simply moves the top of the header element down 50% and then the rest of the content fills in below that, which means that with multiple lines of text it would appear to be slightly below vertically aligned.
A possible fix for multiple lines would be to use a percentage slightly less than 50%.
You can easily use .replace()
as also previously described. But it is also important to keep in mind that strings are immutable. Hence if you do not assign the change you are making to a variable, then you will not see any change.
Let me explain by;
>>stuff = "bin and small"
>>stuff.replace('and', ',')
>>print(stuff)
"big and small" #no change
To observe the change you want to apply, you can assign same or another variable;
>>stuff = "big and small"
>>stuff = stuff.replace("and", ",")
>>print(stuff)
'big, small'
Just use len(arr)
:
>>> import array
>>> arr = array.array('i')
>>> arr.append('2')
>>> arr.__len__()
1
>>> len(arr)
1
Similarly, I needed to create an rpm with just a few files. Since these files were source controlled, and because it seemed silly, I didn't want to go through taring them up just to have rpm untar them. I came up with the following:
Set up your environment:
mkdir -p ~/rpm/{BUILD,RPMS}
echo '%_topdir %(echo "$HOME")/rpm' > ~/.rpmmacros
Create your spec file, foobar.spec, with the following contents:
Summary: Foo to the Bar
Name: foobar
Version: 0.1
Release: 1
Group: Foo/Bar
License: FooBarPL
Source: %{expand:%%(pwd)}
BuildRoot: %{_topdir}/BUILD/%{name}-%{version}-%{release}
%description
%{summary}
%prep
rm -rf $RPM_BUILD_ROOT
mkdir -p $RPM_BUILD_ROOT/usr/bin
mkdir -p $RPM_BUILD_ROOT/etc
cd $RPM_BUILD_ROOT
cp %{SOURCEURL0}/foobar ./usr/bin/
cp %{SOURCEURL0}/foobar.conf ./etc/
%clean
rm -r -f "$RPM_BUILD_ROOT"
%files
%defattr(644,root,root)
%config(noreplace) %{_sysconfdir}/foobar.conf
%defattr(755,root,root)
%{_bindir}/foobar
Build your rpm:
rpmbuild -bb foobar.spec
There's a little hackery there specifying the 'source' as your current directory, but it seemed far more elegant then the alternative, which was to, in my case, write a separate script to create a tarball, etc, etc.
Note: In my particular situation, my files were arranged in folders according to where they needed to go, like this:
./etc/foobar.conf
./usr/bin/foobar
and so the prep section became:
%prep
rm -rf $RPM_BUILD_ROOT
mkdir -p $RPM_BUILD_ROOT
cd $RPM_BUILD_ROOT
tar -cC %{SOURCEURL0} --exclude 'foobar.spec' -f - ./ | tar xf -
Which is a little cleaner.
Also, I happen to be on a RHEL5.6 with rpm versions 4.4.2.3, so your mileage may vary.
You need to append your variables to the echoed string. For example:
echo 'This is a string '.$PHPvariable.' and this is more string';
For Python 3, you need:
list_of_dict_values = list(dict_name.values())
Yes - different
chmod a+x
will add the exec bits to the file but will not touch other bits. For example file might be still unreadable to others
and group
.
chmod 755
will always make the file with perms 755
no matter what initial permissions were.
This may or may not matter for your script.
You can load the text file into a textfile Hive table and then insert the data from this table into your sequencefile.
Start with a tab delimited file:
% cat /tmp/input.txt
a b
a2 b2
create a sequence file
hive> create table test_sq(k string, v string) stored as sequencefile;
try to load; as expected, this will fail:
hive> load data local inpath '/tmp/input.txt' into table test_sq;
But with this table:
hive> create table test_t(k string, v string) row format delimited fields terminated by '\t' stored as textfile;
The load works just fine:
hive> load data local inpath '/tmp/input.txt' into table test_t;
OK
hive> select * from test_t;
OK
a b
a2 b2
Now load into the sequence table from the text table:
insert into table test_sq select * from test_t;
Can also do load/insert with overwrite to replace all.
You'll also get this error if your target element is inside a hidden element. If this is your HTML:
<div *ngIf="false">
<span #sp>Hello World</span>
</div>
Your @ViewChild('sp') sp
will be undefined.
In such a case, then don't use *ngIf
.
Instead use a class to show/hide your element being hidden.
<div [class.show]="shouldShow">...</div>
More stable approach:
<form onsubmit="foo($("#formValueId").val());return false;">
<input type="text" id="formValueId"/>
<input type="submit" value="Text on the button"/>
</form>
The return false;
is to prevent actual form submit (assuming you want that).
First convert list to sets.
// create an empty set
Set<T> set = new HashSet<>();
// Add each element of list into the set
for (T t : list)
set.add(t);
You can use Sets.difference(Set1, Set2)
, which returns extra items present in Set1.
You can use Sets.difference(Set2, Set1)
, which returns extra items present in Set2.
I encountered this issue when installing a different package, and it could be caused by the GOROOT and GOPATH configuration on your PATH. I tend not to set GOROOT because my OS X installation handled it (I believe) for me.
Ensure the following in your .profile (or wherever you store profile configuration: .bash_profile, .zshrc, .bashrc, etc):
export GOPATH=$HOME/go
export PATH=$PATH:$GOROOT/bin
Also, you likely want to unset GOROOT
, as well, in case that path is also incorrect.
Furthermore, be sure to clean your PATH, similarly to what I've done below, just before the GOPATH assignment, i.e.:
export PATH=$HOME/bin:/usr/local/bin:$PATH
export GOPATH=$HOME/go
export PATH=$PATH:$GOROOT/bin
Then, source <.profile>

go get
The Pixastic library does exactly what you want. However, it will only work on browsers that have canvas support. For those older browsers, you'll either need to:
Of course, option #2 isn't very user-friendly. However, if your intent is to provide a pure client-only tool and/or you can't support a fallback back-end cropper (e.g. maybe you're writing a browser extension or offline Chrome app, or maybe you can't afford a decent hosting provider that provides image manipulation libraries), then it's probably fair to limit your user base to modern browsers.
EDIT: If you don't want to learn Pixastic, I have added a very simple cropper on jsFiddle here. It should be possible to modify and integrate and use the drawCroppedImage
function with Jcrop.
SQL Server 2008+ has a "time" datatype
SELECT
..., CAST(MyDateTimeCol AS time)
FROM
...
For older versions, without varchar conversions
SELECT
..., DATEADD(dd, DATEDIFF(dd, MyDateTimeCol, 0), MyDateTimeCol)
FROM
...
I think the easiest way for checking result set is via CollectionUtils under package org.apache.commons.collections.CollectionUtils
if(CollectionUtils.isNotEmpty(resultList)){
/**
* do some stuff
*/
}
This will check for null as well as empty result set condition.
For more detail information you can refer to the following doc. CollectionUtils
You can use an enhanced for loop:
Set<String> set = new HashSet<String>();
//populate set
for (String s : set) {
System.out.println(s);
}
Or with Java 8:
set.forEach(System.out::println);
I have been having the same problem. I followed Bruno's advice to you and found that adding a KeyListener just to the "first" button in the JFrame (ie, on the top left) did the trick. But I agree with you it is kind of an unsettling solution. So I fiddled around and discovered a neater way to fix it. Just add the line
myChildOfJFrame.requestFocusInWindow();
to your main method, after you've created your instance of your subclass of JFrame and set it visible.
var i = 0;_x000D_
var length = 10;_x000D_
_x000D_
function for1() {_x000D_
console.log(i);_x000D_
for2();_x000D_
}_x000D_
_x000D_
function for2() {_x000D_
if (i == length) {_x000D_
return false;_x000D_
}_x000D_
setTimeout(function() {_x000D_
i++;_x000D_
for1();_x000D_
}, 500);_x000D_
}_x000D_
for1();
_x000D_
Here is a sample functional approach to what is expected here.
Both of them are ways of subsetting. The single bracket will return a subset of the list, which in itself will be a list. ie:It may or may not contain more than one elements. On the other hand a double bracket will return just a single element from the list.
-Single bracket will give us a list. We can also use single bracket if we wish to return multiple elements from the list. consider the following list:-
>r<-list(c(1:10),foo=1,far=2);
Now please note the way the list is returned when I try to display it. I type r and press enter
>r
#the result is:-
[[1]]
[1] 1 2 3 4 5 6 7 8 9 10
$foo
[1] 1
$far
[1] 2
Now we will see the magic of single bracket:-
>r[c(1,2,3)]
#the above command will return a list with all three elements of the actual list r as below
[[1]]
[1] 1 2 3 4 5 6 7 8 9 10
$foo
[1] 1
$far
[1] 2
which is exactly the same as when we tried to display value of r on screen, which means the usage of single bracket has returned a list, where at index 1 we have a vector of 10 elements, then we have two more elements with names foo and far. We may also choose to give a single index or element name as input to the single bracket. eg:
> r[1]
[[1]]
[1] 1 2 3 4 5 6 7 8 9 10
In this example we gave one index "1" and in return got a list with one element(which is an array of 10 numbers)
> r[2]
$foo
[1] 1
In the above example we gave one index "2" and in return got a list with one element
> r["foo"];
$foo
[1] 1
In this example we passed the name of one element and in return a list was returned with one element.
You may also pass a vector of element names like:-
> x<-c("foo","far")
> r[x];
$foo
[1] 1
$far
[1] 2
In this example we passed an vector with two element names "foo" and "far"
In return we got a list with two elements.
In short single bracket will always return you another list with number of elements equal to the number of elements or number of indices you pass into the single bracket.
In contrast, a double bracket will always return only one element.
Before moving to double bracket a note to be kept in mind.
NOTE:THE MAJOR DIFFERENCE BETWEEN THE TWO IS THAT SINGLE BRACKET RETURNS YOU A LIST WITH AS MANY ELEMENTS AS YOU WISH WHILE A DOUBLE BRACKET WILL NEVER RETURN A LIST. RATHER A DOUBLE BRACKET WILL RETURN ONLY A SINGLE ELEMENT FROM THE LIST.
I will site a few examples. Please keep a note of the words in bold and come back to it after you are done with the examples below:
Double bracket will return you the actual value at the index.(It will NOT return a list)
> r[[1]]
[1] 1 2 3 4 5 6 7 8 9 10
>r[["foo"]]
[1] 1
for double brackets if we try to view more than one elements by passing a vector it will result in an error just because it was not built to cater to that need, but just to return a single element.
Consider the following
> r[[c(1:3)]]
Error in r[[c(1:3)]] : recursive indexing failed at level 2
> r[[c(1,2,3)]]
Error in r[[c(1, 2, 3)]] : recursive indexing failed at level 2
> r[[c("foo","far")]]
Error in r[[c("foo", "far")]] : subscript out of bounds
For this particular question, the standard suggestion of java.text.SimpleDateFormat
works, but has the unfortunate side effect that SimpleDateFormat
is not thread-safe and can be the source of particularly nasty problems since it'll corrupt your output in multi-threaded scenarios, and you won't get any exceptions!
I would strongly recommend looking at Joda for anything like this. Why ? It's a much richer and more intuitive time/date library for Java than the current library (and the basis of the up-and-coming new standard Java date/time library, so you'll be learning a soon-to-be-standard API).
Here is an example returning a value from an internal List object. Should give you the idea.
public object this[int index]
{
get { return ( List[index] ); }
set { List[index] = value; }
}
Suppose your function enters data in columns A and B and you want to a custom Userform to appear if the user selects a cell in column C. One way to do this is to use the SelectionChange
event:
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
Dim clickRng As Range
Dim lastRow As Long
lastRow = Range("A1").End(xlDown).Row
Set clickRng = Range("C1:C" & lastRow) //Dynamically set cells that can be clicked based on data in column A
If Not Intersect(Target, clickRng) Is Nothing Then
MyUserForm.Show //Launch custom userform
End If
End Sub
Note that the userform will appear when a user selects any cell in Column C and you might want to populate each cell in Column C with something like "select cell to launch form" to make it obvious that the user needs to perform an action (having a button naturally suggests that it should be clicked)
Try
alter table company drop constraint Company_CountryID_FK
alter table company drop column CountryID
When you say pair[0]
, that gives you ("a", 1)
. The thing in parentheses is a tuple, which, like a list, is a type of collection. So you can access the first element of that thing by specifying [0]
or [1]
after its name. So all you have to do to get the first element of the first element of pair
is say pair[0][0]
. Or if you want the second element of the third element, it's pair[2][1]
.

$myarray = array(
'test1' => 'foo',
'test2' => 'bar',
'test3' => 'baz',
'test4' => 'waldo'
);
$myarray2 = array(
'foo',
'bar',
'baz',
'waldo'
);
// Get the last array_key
$last = array_pop(array_keys($myarray));
foreach($myarray as $key => $value) {
if($key != $last) {
echo "$key -> $value\n";
}
}
// Get the last array_key
$last = array_pop(array_keys($myarray2));
foreach($myarray2 as $key => $value) {
if($key != $last) {
echo "$key -> $value\n";
}
}
Since array_pop
works on the temporary array created by array_keys
it doesn't modify the original array at all.

There are two ways:
ax.set_xticks
and ax.set_xticklabels
) orplt.sca
to set the current axes for the pyplot state machine (i.e. the plt
interface).As an example (this also illustrates using setp
to change the properties of all of the subplots):
import matplotlib.pyplot as plt
fig, axes = plt.subplots(nrows=3, ncols=4)
# Set the ticks and ticklabels for all axes
plt.setp(axes, xticks=[0.1, 0.5, 0.9], xticklabels=['a', 'b', 'c'],
yticks=[1, 2, 3])
# Use the pyplot interface to change just one subplot...
plt.sca(axes[1, 1])
plt.xticks(range(3), ['A', 'Big', 'Cat'], color='red')
fig.tight_layout()
plt.show()
I'd probably use all.equal
and which
to get the information you want. It's not recommended to use all.equal
in an if...else
block for some reason, so we wrap it in isTRUE()
. See ?all.equal
for more:
foo <- function(A,B){
if (!isTRUE(all.equal(A,B))){
mismatches <- paste(which(A != B), collapse = ",")
stop("error the A and B does not match at the following columns: ", mismatches )
} else {
message("Yahtzee!")
}
}
And in use:
> foo(A,A)
Yahtzee!
> foo(A,B)
Yahtzee!
> foo(A,C)
Error in foo(A, C) :
error the A and B does not match at the following columns: 2,4
The easiest way to do this is by using the below function, which is built in:
format()
For example:
format(1.242563,".2f")
The output would be:
1.24
Similarly:
format(9.165654,".1f")
would give:
9.2
This first choice might be a confusing one but it’s really very simple. PhoneGap is a product owned by Adobe which currently includes additional build services, and it may or may not eventually offer additional services and/or charge payments for use in the future. Cordova is owned and maintained by Apache, and will always be maintained as an open source project. Currently they both have a very similar API. I would recommend going with Cordova, unless you require the additional PhoneGap build services.
tell you the true, I still don't get what you need, but
window.location(url);
should be
window.location = url;
a search on window.location reference will tell you that.
use further as
rs.getString(1);
rs.getInt(2);
1, 2 is the column number of table and set int or string as per data-type of coloumn
I tried the steps that @KannarKK suggested on ES 2.0.2, however, I could not bring the cluster up and running. Evidently, I figured out something, as I had set tcp port number on Master, on the Slave configuration discovery.zen.ping.unicast.hosts needs Master's port number along with IP address ( tcp port number ) for discovery. So when I try following configuration it works for me.
Node 1
cluster.name: mycluster
node.name: "node1"
node.master: true
node.data: true
http.port : 9200
tcp.port : 9300
discovery.zen.ping.multicast.enabled: false
# I think unicast.host on master is redundant.
discovery.zen.ping.unicast.hosts: ["node1.example.com"]
Node 2
cluster.name: mycluster
node.name: "node2"
node.master: false
node.data: true
http.port : 9201
tcp.port : 9301
discovery.zen.ping.multicast.enabled: false
# The port number of Node 1
discovery.zen.ping.unicast.hosts: ["node1.example.com:9300"]
I think this example explains clearly the differences between inheritance and composition.
In this exmple, the problem is solved using inheritance and composition. The author pays attention to the fact that ; in inheritance, a change in superclass might cause problems in derived class, that inherit it.
There you can also see the difference in representation when you use a UML for inheritance or composition.
To remove the file from the index, use:
git reset myfile
This should not affect your local copy or anyone else's.
