ORA-01775: looping chain of synonyms I faced the above error while I was trying to compile a Package which was using an object for which synonym was created however underlying object was not available.
Why not use index or rindex?
array = %w( a b c d e)
# get FIRST index of element searched
puts array.index('a')
# get LAST index of element searched
puts array.rindex('a')
index: http://www.ruby-doc.org/core-1.9.3/Array.html#method-i-index
rindex: http://www.ruby-doc.org/core-1.9.3/Array.html#method-i-rindex

int width = 20; /* or whatever you need but less than BUFSIZ ;) */
printf("%s%s\n", (char*)memset(buf, fill, width - strlen(str)), str);

Perhaps a more logical method would be to create a file (e.g. test.html), add some content and then try to set it as the index page:
DirectoryIndex test.html
For the most part, the .htaccess rule will override the Apache configuration where working at the directory/file level
Save this class in the file StaticDemo.java. Also you cant have more than one public classes in one file.
For What its worth, this is what I did and maybe it can help others even though the article is old.
PHP:
session_start();
$_SESSION['ipaddress'] = $_SERVER['REMOTE_ADDR'];
if(isset($_SESSION['userID'])){
if(!strpos($_SESSION['activeID'], '-')){
$_SESSION['activeID'] = $_SESSION['userID'].'-'.$_SESSION['activeID'];
}
}elseif(!isset($_SESSION['activeID'])){
$_SESSION['activeID'] = time();
}
JS
window.setInterval(function(){
var userid = '<?php echo $_SESSION['activeID']; ?>';
var ipaddress = '<?php echo $_SESSION['ipaddress']; ?>';
var action = 'data';
$.ajax({
url:'activeUser.php',
method:'POST',
data:{action:action,userid:userid,ipaddress:ipaddress},
success:function(response){
//alert(response);
}
});
}, 5000);
Ajax call to activeUser.php
if(isset($_POST['action'])){
if(isset($_POST['userid'])){
$stamp = time();
$activeid = $_POST['userid'];
$ip = $_POST['ipaddress'];
$query = "SELECT stamp FROM activeusers WHERE activeid = '".$activeid."' LIMIT 1";
$results = RUNSIMPLEDB($query);
if($results->num_rows > 0){
$query = "UPDATE activeusers SET stamp = '$stamp' WHERE activeid = '".$activeid."' AND ip = '$ip' LIMIT 1";
RUNSIMPLEDB($query);
}else{
$query = "INSERT INTO activeusers (activeid,stamp,ip)
VALUES ('".$activeid."','$stamp','$ip')";
RUNSIMPLEDB($query);
}
}
}
Database:
CREATE TABLE `activeusers` (
`id` int(11) NOT NULL,
`activeid` varchar(20) NOT NULL,
`stamp` int(11) NOT NULL,
`ip` text
) ENGINE=MyISAM DEFAULT CHARSET=utf8;
Basically every 5 seconds the js will post to a php file that will track the user and the users ip address. Active users are simply a database record that have an update to the database time stamp within 5 seconds. Old users stop updating to the database. The ip address is used just to ensure that a user is unique so 2 people on the site at the same time don't register as 1 user.
Probably not the most efficient solution but it does the job.
This is what Sun-Oracle documentation says:
Package names are written in all lower case to avoid conflict with the names of classes or interfaces.
Companies use their reversed Internet domain name to begin their package names—for example, com.example.mypackage for a package named mypackage created by a programmer at example.com.
The naming convention is part of the well-established JavaBeans specification and is supported by the classes in the java.beans package.
You mean this?
from string import punctuation, digits
takeout = punctuation + digits
turnthis = "(fjskl) 234 = -345 089 abcdef"
turnthis = turnthis.translate(None, takeout)[::-1]
print turnthis
I was looking for a solution for this and found this great article explaining the solution Relevant excerpt
My all-time-favorite use of ROWNUM is pagination. In this case, I use ROWNUM to get rows N through M of a result set. The general form is as follows:
select * enter code here
from ( select /*+ FIRST_ROWS(n) */
a.*, ROWNUM rnum
from ( your_query_goes_here,
with order by ) a
where ROWNUM <=
:MAX_ROW_TO_FETCH )
where rnum >= :MIN_ROW_TO_FETCH;
Now with a real example (gets rows 148, 149 and 150):
select *
from
(select a.*, rownum rnum
from
(select id, data
from t
order by id, rowid) a
where rownum <= 150
)
where rnum >= 148;
In SQL Server Management Studio, go to Object Explorer > (your server) > Security > Logins
and right-click New Login
:
Then in the dialog box that pops up, pick the types of objects you want to see (Groups
is disabled by default - check it!) and pick the location where you want to look for your objects (e.g. use Entire Directory
) and then find your AD group.
You now have a regular SQL Server Login - just like when you create one for a single AD user. Give that new login the permissions on the databases it needs, and off you go!
Any member of that AD group can now login to SQL Server and use your database.
Look at how the built-in containers do it. dict
and list
and so on contain heterogeneous elements of whatever types you like. If you define, say, an insert(val)
function for your tree, it will at some point do something like node.value = val
and Python will take care of the rest.
in your code, at line
map.setCenter(new GLatLng(lat, lon), 5);
the setCenter method takes just one parameter, for the lat:long location. Why are you passing two parameters there ?
I suggest you should change it to,
map.setCenter(new GLatLng(lat, lon));
There is a faster way I found that does not require looping through the entire file
only on *nix systems, there might be a similar way on windows ...
$file = '/path/to/your.file';
//Get number of lines
$totalLines = intval(exec("wc -l '$file'"));
You have to understand that Python represents all its data as objects. Some of these objects like lists and dictionaries are mutable, meaning you can change their content without changing their identity. Other objects like integers, floats, strings and tuples are objects that can not be changed. An easy way to understand that is if you have a look at an objects ID.
Below you see a string that is immutable. You can not change its content. It will raise a TypeError
if you try to change it. Also, if we assign new content, a new object is created instead of the contents being modified.
>>> s = "abc"
>>>id(s)
4702124
>>> s[0]
'a'
>>> s[0] = "o"
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: 'str' object does not support item assignment
>>> s = "xyz"
>>>id(s)
4800100
>>> s += "uvw"
>>>id(s)
4800500
You can do that with a list and it will not change the objects identity
>>> i = [1,2,3]
>>>id(i)
2146718700
>>> i[0]
1
>>> i[0] = 7
>>> id(i)
2146718700
To read more about Python's data model you could have a look at the Python language reference:
There should be only one localhost defined, check sites-enabled or nginx.conf.

In my case, I was getting this error message only in Production but not when run locally, even though my application's binaries were identical.
In my application, I'm using a custom DbModelStore
so that the runtime-generated EDMX is saved to disk and loaded from disk on startup (instead of regenerating it from scratch) to reduce application startup time - and due to a bug in my code I wasn't invalidating the EDMX file on-disk - so Production was using an older version of the EDMX file from disk that referenced an older version of my application's types from before I renamed the type-name in the exception error message.
Deleting the cache file and restarting the application fixed it.
Here's the simplest solution (Jibwa made it seem complicated in another answer), without having to generate indices yourself - just using the ShuffleSplit object to generate 1 split.
import numpy as np
from sklearn.model_selection import ShuffleSplit # or StratifiedShuffleSplit
sss = ShuffleSplit(n_splits=1, test_size=0.1)
data_size = 100
X = np.reshape(np.random.rand(data_size*2),(data_size,2))
y = np.random.randint(2, size=data_size)
sss.get_n_splits(X, y)
train_index, test_index = next(sss.split(X, y))
X_train, X_test = X[train_index], X[test_index]
y_train, y_test = y[train_index], y[test_index]
This is likely because you haven't set your compileSdkVersion
to 21 in your build.gradle file. You also probably want to change your targetSdkVersion
to 21.
android {
//...
compileSdkVersion 21
defaultConfig {
targetSdkVersion 21
}
//...
}
This requires you to have downloaded the latest SDK updates to begin with.
Once you've downloaded all the updates (don't forget to also update the Android Support Library/Repository, too!) and updated your compileSdkVersion, re-sync your Gradle project.
Edit: For Eclipse or general IntelliJ users
See reVerse's answer. He has a very thorough walk through!
So long as you're testing files on the same domain this should work:
function fileExists(url) {
if(url){
var req = new XMLHttpRequest();
req.open('GET', url, false);
req.send();
return req.status==200;
} else {
return false;
}
}
Please note, this example is using a GET request, which besides getting the headers (all you need to check weather the file exists) gets the whole file. If the file is big enough this method can take a while to complete.
The better way to do this would be changing this line: req.open('GET', url, false);
to req.open('HEAD', url, false);
display:none;
removes a block from the page as if it were never there. A block cannot be partially displayed; it’s either there or it’s not. The same is true forvisibility
; you can’t expect a block to be halfhidden
which, by definition, would bevisible
! Fortunately, you can useopacity
for fading effects instead.

As an alternatiive CSS solution, you could play with opacity
, height
and padding
properties to achieve the desirable effect:
#header #button:hover > .content {
opacity:1;
height: 150px;
padding: 8px;
}
#header #button .content {
opacity:0;
height: 0;
padding: 0 8px;
overflow: hidden;
transition: all .3s ease .15s;
}
(Vendor prefixes omitted due to brevity.)

The dat file has some lines of extra information before the actual data. Skip them with the skip
argument:
read.table("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat",
header=TRUE, skip=3)
An easy way to check this if you are unfamiliar with the dataset is to first use readLines
to check a few lines, as below:
readLines("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat",
n=10)
# [1] "Ozone data from CZ03 2009" "Local time: GMT + 0"
# [3] "" "Date Hour Value"
# [5] "01.01.2009 00:00 34.3" "01.01.2009 01:00 31.9"
# [7] "01.01.2009 02:00 29.9" "01.01.2009 03:00 28.5"
# [9] "01.01.2009 04:00 32.9" "01.01.2009 05:00 20.5"
Here, we can see that the actual data starts at [4]
, so we know to skip the first three lines.
If you really only wanted the Value
column, you could do that by:
as.vector(
read.table("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat",
header=TRUE, skip=3)$Value)
Again, readLines
is useful for helping us figure out the actual name of the columns we will be importing.
But I don't see much advantage to doing that over reading the whole dataset in and extracting later.
As A.B.Cada pointed out, you can query the database itself with sqlplus for the db version. That is the easiest way to findout what is the version of the db that is actively running. If there is more than one you will have to set the oracle_sid appropriately and run the query against each instance.
You can view /etc/oratab file to see what instance and what db home is used per instance. Its possible to have multiple version of oracle installed per server as well as multiple instances. The /etc/oratab file will list all instances and db home. From with the oracle db home you can run "opatch lsinventory" to find out what exaction version of the db is installed as well as any patches applied to that db installation.
url
isn't an object on the Marker class. But there's nothing stopping you adding that as a property to that class. I'm guessing whatever example you were looking at did that too. Do you want a different URL for each marker? What happens when you do:
for (var i = 0; i < locations.length; i++)
{
var flag = new google.maps.MarkerImage('markers/' + (i + 1) + '.png',
new google.maps.Size(17, 19),
new google.maps.Point(0,0),
new google.maps.Point(0, 19));
var place = locations[i];
var myLatLng = new google.maps.LatLng(place[1], place[2]);
var marker = new google.maps.Marker({
position: myLatLng,
map: map,
icon: flag,
shape: shape,
title: place[0],
zIndex: place[3],
url: "/your/url/"
});
google.maps.event.addListener(marker, 'click', function() {
window.location.href = this.url;
});
}

AssemblyInformationalVersion
and AssemblyFileVersion
are displayed when you view the "Version" information on a file through Windows Explorer by viewing the file properties. These attributes actually get compiled in to a VERSION_INFO
resource that is created by the compiler.
AssemblyInformationalVersion
is the "Product version" value. AssemblyFileVersion
is the "File version" value.
The AssemblyVersion
is specific to .NET assemblies and is used by the .NET assembly loader to know which version of an assembly to load/bind at runtime.
Out of these, the only one that is absolutely required by .NET is the AssemblyVersion
attribute. Unfortunately it can also cause the most problems when it changes indiscriminately, especially if you are strong naming your assemblies.
Have you tried before and after rather than >= and <=? Also, is this a date or a timestamp?
CPython actually implements the datetime module using both a pure-Python Lib/datetime.py and a C-optimized Modules/_datetimemodule.c. The C-optimized version cannot be patched but the pure-Python version can.
At the bottom of the pure-Python implementation in Lib/datetime.py is this code:
try:
from _datetime import * # <-- Import from C-optimized module.
except ImportError:
pass
This code imports all the C-optimized definitions and effectively replaces all the pure-Python definitions. We can force CPython to use the pure-Python implementation of the datetime module by doing:
import datetime
import importlib
import sys
sys.modules["_datetime"] = None
importlib.reload(datetime)
By setting sys.modules["_datetime"] = None
, we tell Python to ignore the C-optimized module. Then we reload the module which causes the import from _datetime
to fail. Now the pure-Python definitions remain and can be patched normally.
If you're using Pytest then include the snippet above in conftest.py and you can patch datetime
objects normally.
I had the same problem and for some reason The sshKeys was not syncing up with my user on the instance.
I created another user by adding --ssh_user=anotheruser to gcutil command.
The gcutil looked like this
gcutil --service_version="v1" --project="project" --ssh_user=anotheruser ssh --zone="us-central1-a" "inst1"
You can always check if the thread's id is different than std::thread::id() default constructed. A Running thread has always a genuine associated id. Try to avoid too much fancy stuff :)
This is a new answer to an old question about a common misconception about contains()
in XPath...
Summary: contains()
means contains a substring, not contains a node.
This XPath is often misinterpreted:
//ul[contains(li, 'Model')]
Wrong interpretation:
Select those ul
elements that contain an li
element with Model
in it.
This is wrong because
contains(x,y)
expects x
to be a string, andthe XPath rule for converting multiple elements to a string is this:
A node-set is converted to a string by returning the string-value of the node in the node-set that is first in document order. If the node-set is empty, an empty string is returned.
Right interpretation: Select those ul
elements whose first li
child has a string-value that contains a Model
substring.

</ul>
</r>
XPaths
//ul[contains(li, 'Model')]
selects the one
ul
element.
Note: The two
ul
element is not selected because the string-value of the first li
child
of the two
ul
is Foo
, which does not contain the Model
substring.
//ul[li[contains(.,'Model')]]
selects the one
and two
ul
elements.
Note: Both ul
elements are selected because contains()
is applied to each li
individually. (Thus, the tricky multiple-element-to-string conversion rule is avoided.) Both ul
elements do have an li
child whose string value contains the Model
substring -- position of the li
element no longer matters.
Just add below lines in your POJO before start of class ,and your issue is resolved. @Produces("application/json") @XmlRootElement See example import javax.ws.rs.Produces; import javax.xml.bind.annotation.XmlRootElement;

}
public void setPassword(String password) {
this.password = password;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {

Now recompile your webservice everything would work!!!
Assuming the objects in your source array have an id property...
var $local_source = [
{ id: 1, value: "c++" },
{ id: 2, value: "java" },
{ id: 3, value: "php" },
{ id: 4, value: "coldfusion" },
{ id: 5, value: "javascript" },
{ id: 6, value: "asp" },
{ id: 7, value: "ruby" }];
Getting hold of the current instance and inspecting its selectedItem property will allow you to retrieve the properties of the currently selceted item. In this case alerting the id of the selected item.
$('#button').click(function() {
alert($("#txtAllowSearch").autocomplete("instance").selectedItem.id;
});
You may be overcomplicating things, is there any reason you need the stringr package?
df <- data.frame(Date = c("10/9/2009 0:00:00", "10/15/2009 0:00:00"))
as.Date(df$Date, "%m/%d/%Y %H:%M:%S")
[1] "2009-10-09" "2009-10-15"
More generally and if you need the time component as well, use strptime:
strptime(df$Date, "%m/%d/%Y %H:%M:%S")
I'm guessing at what your actual data might look at from the partial results you give.
Not sure if I am late to the party but I found this nice example that overrides the JSONObject constructor and makes sure that the JSON data are output in the same way as they are added. Behind the scenes JSONObject uses the MAP and MAP does not guarantee the order hence we need to override it to make sure we are receiving our JSON as per our order.
If you add this to your JSONObject then the resulting JSON would be in the same order as you have created it.

http://code.google.com/p/py2c/ looks like a possibility - they also mention on their site: Cython, Shedskin and RPython and confirm that they are converting Python code to pure C/C++ which is much faster than C/C++ riddled with Python API calls. Note: I haven’t tried it but I am going to..
The exception occurs due to this statement,
called_from.equalsIgnoreCase("add")
It seem that the previous statement
String called_from = getIntent().getStringExtra("called");
returned a null reference.
You can check whether the intent to start this activity contains such a key "called".
I'm afraid that there is no easy to do this in Scipy to my knowledge. You can, as I'm fairly sure that you are aware, turn off the bounds errors and fill all function values beyond the range with a constant, but that doesn't really help. See this question on the mailing list for some more ideas. Maybe you could use some kind of piecewise function, but that seems like a major pain.
SOAP (Simple Object Access Protocol) is the communication protocol in the web service scenario.
One benefit of SOAP is that it allowas RPC to execute through a firewall. But to pass through a firewall, you will probably want to use 80. it uses port no.8084 To the firewall, a SOAP conversation on 80 looks like a POST to a web page. However, there are extensions in SOAP which are specifically aimed at the firewall. In the future, it may be that firewalls will be configured to filter SOAP messages. But as of today, most firewalls are SOAP ignorant.
so exclusively open SOAP Port in Firewalls
As a completion to Gustavo Bezerra's answer:
If you want each histogram to be normalized (normed
for mpl<=2.1 and density
for mpl>=3.1) you cannot just use normed/density=True
, you need to set the weights for each value instead:
import numpy as np
import matplotlib.pyplot as plt
x = np.random.normal(1, 2, 5000)
y = np.random.normal(-1, 3, 2000)
x_w = np.empty(x.shape)
x_w.fill(1/x.shape[0])
y_w = np.empty(y.shape)
y_w.fill(1/y.shape[0])
bins = np.linspace(-10, 10, 30)
plt.hist([x, y], bins, weights=[x_w, y_w], label=['x', 'y'])
plt.legend(loc='upper right')
plt.show()
As a comparison, the exact same x
and y
vectors with default weights and density=True
:
According to SLF4J official documentation
Failed to load class org.slf4j.impl.StaticLoggerBinder
This warning message is reported when the org.slf4j.impl.StaticLoggerBinder class could not be loaded into memory. This happens when no appropriate SLF4J binding could be found on the class path. Placing one (and only one) of slf4j-nop.jar, slf4j-simple.jar, slf4j-log4j12.jar, slf4j-jdk14.jar or logback-classic.jar on the class path should solve the problem.
Simply add this jar along with slf4j api.jar to your classpath to get things done. Best of luck
Here is a better solution which does not clip and/or blur the drawable, but only works if the checkbox doesn't have text itself (but you can still have text, it's just more complicated, see at the end).
<CheckBox
android:id="@+id/item_switch"
android:layout_width="160dp" <!-- This is the size you want -->
android:layout_height="160dp"
android:button="@null"
android:background="?android:attr/listChoiceIndicatorMultiple"/>
The result:
What the previous solution with scaleX
and scaleY
looked like:
You can have a text checkbox by adding a TextView
beside it and adding a click listener on the parent layout, then triggering the checkbox programmatically.
Another one is OxyPlot, which is an open-source cross-platform (WPF, Silverlight, WinForms, Mono) .Net plotting library.
The Request.Form.Keys collection will be empty if none of your html inputs have NAMEs. It's easy to forget to put them there after you've been doing .NET for a while. Just name them and you'll be good to go.
If you are using Resharper make sure it does not add the wrong header for you, very common cases with ReSharper are:
#include <consoleapi2.h
#include <apiquery2.h>
#include <fileapi.h>
UPDATE:
Another suggestion is to check if you are including a "partial Windows.h", what I mean is that if you include for example winbase.h or minwindef.h you may end up with that error, add "the big" Windows.h instead. There are also some less obvious cases that I went through, the most notable was when I only included synchapi.h, the docs clearly state that is the header to be included for some functions like AcquireSRWLockShared but it triggered the No target architecture, the fix was to remove the synchapi.h and include "the big" Windows.h.
The Windows.h is huge, it defines macros(many of them remove the No target arch error) and includes many other headers. In summary, always check if you are including some header that could be replaced by Windows.h because it is not unusual to include a header that relies on some constants that are defined by Windows.h, so if you fail to include this header your compilation may fail.
In case you want to clone a specific branch only, then,
git clone -b <branch-name> <repo-url> <destination-folder-name>
for example,
git clone -b dev https://github.com/sferik/sign-in-with-twitter.git signin
This happened to me too, because I had my id as Long, and I was receiving from the view the value 0, and when I tried to save in the database I got this error, then I fixed it by set the id to null.
Here is how this particular deadlock problem actually occurred and how it was actually resolved. This is a fairly active database with 130K transactions occurring daily. The indexes in the tables in this database were originally clustered. The client requested us to make the indexes nonclustered. As soon as we did, the deadlocking began. When we reestablished the indexes as clustered, the deadlocking stopped.
Converting the date without specifying the current format can bring this error to you easily.
sdate <- "2015.10.10"
date <- as.Date(sdate4) # ==> This will generate the same error"""Error in charToDate(x): character string is not in a standard unambiguous format""".
date <- as.Date(sdate4, format = "%Y.%m.%d") # ==> Error Free Date Conversion.
Not really as far as I know but here are couple things you can try.
Third party tools: Create empty database on 2008 instance and use third party tools such as ApexSQL Diff and Data Diff to synchronize schema and tables.
Just use these (or any other on the market such as Red Gate, Idera, Dev Art, there are many similar) in trial mode to get the job done.
Generate scripts: Go to Tasks -> Generate Scripts, select option to script the data too and execute it on 2008 instance. Works just fine but note that script order is something you must be careful about. By default scripts are not ordered to take dependencies into account.
This can be done using stream:
List<String> stringList = Arrays.asList("abc#bcd", "mno#pqr");
List<String[]> objects = stringList.stream()
.map(s -> s.split("#"))
.collect(Collectors.toList());
The return value would be arrays of split string. This avoids converting the arraylist to an array and performing the operation.
Where the usage of a regex can be helpful to determine if the character sequence of a date is correct, it cannot be used easily to determine if the date is valid. The following examples will pass the regular expression, but are all invalid dates: 20180231, 20190229, 20190431
So if you want to validate if your date string (let's call it datestr
) is in the correct format, it is best to parse it with date
and ask date
to convert the string to the correct format. If both strings are identical, you have a valid format and valid date.
if [[ "$datestr" == $(date -d "$datestr" "+%Y%m%d" 2>/dev/null) ]]; then
echo "Valid date"
else
echo "Invalid date"
fi

This is the most simple example I can think of in this case and is not tested. Please consider that this uses some bad practices and does not go the way you normally would go with C++ (initialize lists, separation of declaration and definition, and so on). But that are topics I can't cover here.
#include <iostream>
using namespace std;
class LinkedList{
// Struct inside the class LinkedList
// This is one node which is not needed by the caller. It is just
// for internal work.
struct Node {
int x;
Node *next;
};
// public member
public:
// constructor
LinkedList(){
head = NULL; // set head to NULL
}
// destructor
~LinkedList(){
Node *next = head;
while(next) { // iterate over all elements
Node *deleteMe = next;
next = next->next; // save pointer to the next element
delete deleteMe; // delete the current entry
}
}
// This prepends a new value at the beginning of the list
void addValue(int val){
Node *n = new Node(); // create new Node
n->x = val; // set value
n->next = head; // make the node point to the next node.
// If the list is empty, this is NULL, so the end of the list --> OK
head = n; // last but not least, make the head point at the new node.
}
// returns the first element in the list and deletes the Node.
// caution, no error-checking here!
int popValue(){
Node *n = head;
int ret = n->x;
head = head->next;
delete n;
return ret;
}
// private member
private:
Node *head; // this is the private member variable. It is just a pointer to the first Node
};
int main() {
LinkedList list;
list.addValue(5);
list.addValue(10);
list.addValue(20);
cout << list.popValue() << endl;
cout << list.popValue() << endl;
cout << list.popValue() << endl;
// because there is no error checking in popValue(), the following
// is undefined behavior. Probably the program will crash, because
// there are no more values in the list.
// cout << list.popValue() << endl;
return 0;
}
I would strongly suggest you to read a little bit about C++ and Object oriented programming. A good starting point could be this: http://www.galileocomputing.de/1278?GPP=opoo
EDIT: added a pop function and some output. As you can see the program pushes 3 values 5, 10, 20 and afterwards pops them. The order is reversed afterwards because this list works in stack mode (LIFO, Last in First out)
Within the parent, you can reference the child using @ViewChild. When needed (i.e. when the event would be fired), you can just execute a method in the child from the parent using the @ViewChild reference.
There is a very simple way to remove browser cache for http redirects e.g. 301, 307 etc.
You can open network panel in developer console in chrome. Select the network call. Right click on it and then click on Clear Browser Cache to remove the cached redirection.

You can also use pathlib

path = Path(file_to_search)
text = path.read_text()
text = text.replace(text_to_search, replacement_text)
path.write_text(text)
If its calling spring boot service. you can handle it using below code.
@Bean
public WebMvcConfigurer corsConfigurer() {
return new WebMvcConfigurerAdapter() {
@Override
public void addCorsMappings(CorsRegistry registry) {
registry.addMapping("/**")
.allowedOrigins("*")
.allowedMethods("GET", "POST", "PUT", "DELETE", "HEAD", "OPTIONS")
.allowedHeaders("*", "Access-Control-Allow-Headers", "origin", "Content-type", "accept", "x-requested-with", "x-requested-by") //What is this for?
.allowCredentials(true);
}
};
}
Use the -o ConnectTimeout
and -o BatchMode=yes -o StrictHostKeyChecking=no
.
ConnectTimeout keeps the script from hanging, BatchMode keeps it from hanging with Host unknown, YES to add to known_hosts, and StrictHostKeyChecking adds the fingerprint automatically.
**** NOTE **** The "StrictHostKeyChecking" was only intended for internal networks where you trust you hosts. Depending on the version of the SSH client, the "Are you sure you want to add your fingerprint" can cause the client to hang indefinitely (mainly old versions running on AIX). Most modern versions do not suffer from this issue. If you have to deal with fingerprints with multiple hosts, I recommend maintaining the known_hosts file with some sort of configuration management tool like puppet/ansible/chef/salt/etc.

On this page, the Arduino sketch defines a couple of Structs (plus a couple of methods) which are then called in the setup loop and main loop. Simple enough to interpret, even for a barely-literate programmer like me.
Pickle is a module installed for both Python 2 and Python 3 by default. See the standard library for 3.6.4 and 2.7.
Also to prove what I am saying is correct try running this script:
import pickle
print(pickle.__doc__)
This will print out the Pickle documentation showing you all the functions (and a bit more) it provides.
Or you can start the integrated Python 3.6 Module Docs and check there.
As a rule of thumb: if you can import the module without an error being produced then it is installed
The reason for the No matching distribution found for pickle
is because libraries for included packages are not available via pip because you already have them (I found this out yesterday when I tried to install an integrated package).
If it's running without errors but it doesn't work as expected I would think that you made a mistake somewhere (perhaps quickly check the functions you are using in the docs). Python is very informative with it's errors so we generally know if something is wrong.
your question is basically O/RM's vs hand writing SQL
Take a look at some of the other O/RM solutions out there, L2S isn't the only one (NHibernate, ActiveRecord)

Scott Guthrie has made a post on how to change Visual Studio's default browser:
1) Right click on a .aspx page in your solution explorer
2) Select the "browse with" context menu option
3) In the dialog you can select or add a browser. If you want Firefox in the list, click "add" and point to the firefox.exe filename
4) Click the "Set as Default" button to make this the default browser when you run any page on the site.
I however dislike the fact that this isn't as straightforward as it should be.
Have you tried this?
$("#notification").fadeOut(300, function(){
$(this).remove();
});
That is, using the current this context to target the element in the inner function and not the id. I use this pattern all the time - it should work.
Just because you're in PowerShell don't forgot about good ol' exes. Sometimes they can provide the easiest solution e.g.:
icacls.exe $folder /grant 'domain\user:(OI)(CI)(M)'
Those do both mean non-breaking space, yes.

I was only interested for a trigger when a width of an element was changed (I don' care about height), so I created a jquery event that does exactly that, using an invisible iframe element.
$.event.special.widthChanged = {
remove: function() {
$(this).children('iframe.width-changed').remove();
},
add: function () {
var elm = $(this);
var iframe = elm.children('iframe.width-changed');
if (!iframe.length) {
iframe = $('<iframe/>').addClass('width-changed').prependTo(this);
}
var oldWidth = elm.width();
function elmResized() {
var width = elm.width();
if (oldWidth != width) {
elm.trigger('widthChanged', [width, oldWidth]);
oldWidth = width;
}
}
var timer = 0;
var ielm = iframe[0];
(ielm.contentWindow || ielm).onresize = function() {
clearTimeout(timer);
timer = setTimeout(elmResized, 20);
};
}
}
It requires the following css :
iframe.width-changed {
width: 100%;
display: block;
border: 0;
height: 0;
margin: 0;
}
You can see it in action here widthChanged fiddle
There could be several things causing this and it somewhat depends on what you have set up in your database.
First, you could be using a PK in the table that is also an FK to another table making the relationship 1-1. IN this case you may need to do an update rather than an insert. If you really can have only one address record for an order this may be what is happening.
Next you could be using some sort of manual process to determine the id ahead of time. The trouble with those manual processes is that they can create race conditions where two records gab the same last id and increment it by one and then the second one can;t insert.
Third, you query as it is sent to the database may be creating two records. To determine if this is the case, Run Profiler to see exactly what SQL code you are sending and if ti is a select instead of a values clause, then run the select and see if you have due to the joins gotten some records to be duplicated. IN any even when you are creating code on the fly like this the first troubleshooting step is ALWAYS to run Profiler and see if what got sent was what you expected to be sent.
You can change the value of tuple using copy by reference
>>> tuple1=[20,30,40]
>>> tuple2=tuple1
>>> tuple2
[20, 30, 40]
>>> tuple2[1]=10
>>> print(tuple2)
[20, 10, 40]
>>> print(tuple1)
[20, 10, 40]
I've found the issue happens when you have multiple projects building in parallel and one or more of the projects are attempting to copy the same files, creating race conditions that will result in occasional errors. So how to solve it?
There's a lot of options, as above just changing things around could solve the issue for some people. More robust solutions would be...
Restrict the files being copied i.e. instead of xcopy $(TargetDir)*.*"
... instead do xcopy "$(TargetDir)$(TargetName).*"
...
Catch the error and retry i.e:
:loop
xcopy /Y /R /S /J /Q "$(TargetDir)$(TargetName).*" "somewhere"
if ErrorLevel 1 goto loop
Use robocopy instead of xcopy
You probably won't want to do this as it will increase your build times, but you could reduce the maximum number of parallel project builds to 1 ...
I think you want to give Share button, clicking on which the suitable media/website option should be there to share with it. In Android, you need to create createChooser
for the same.
Sharing Text:
Intent sharingIntent = new Intent(Intent.ACTION_SEND);
sharingIntent.setType("text/plain");
sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, "This is the text that will be shared.");
startActivity(Intent.createChooser(sharingIntent,"Share using"));
Sharing binary objects (Images, videos etc.)
Intent sharingIntent = new Intent(Intent.ACTION_SEND);
Uri screenshotUri = Uri.parse(path);
sharingIntent.setType("image/png");
sharingIntent.putExtra(Intent.EXTRA_STREAM, screenshotUri);
startActivity(Intent.createChooser(sharingIntent, "Share image using"));
FYI, above code are referred from Sharing content in Android using ACTION_SEND Intent
It is a good question and unfortunately bad answers as var = None
is already assigning a value, and if your script runs multiple times it is overwritten with None
every time.
It is not the same as defining without assignment. I am still trying to figure out how to bypass this issue.
You should push the new viewcontroller by using current navigation controller, not present.
self.navigationController.pushViewController(nextViewController, animated: true)
Use git archive branch-index | tar -x -C your-folder-on-PC
to clone a branch to another folder. I think, then you can copy any file that you need
In my case, I had to load the Map on my Wordpress website and the problem was that the Google's api script was loading before the initMap(). Therefore, I solved the problem with a delay:
<script>
function initMap() {
// Your Javascript Codes for the map
...
}
<?php
// Delay for 5 seconds
sleep(5);
?>
</script>
<script async defer src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEYWY&callback=initMap"></script>
You could try the following:
import matplotlib.pyplot as plt
import numpy as np
def plot_figures(figures, nrows = 1, ncols=1):
"""Plot a dictionary of figures.
Parameters
----------
figures : <title, figure> dictionary
ncols : number of columns of subplots wanted in the display
nrows : number of rows of subplots wanted in the figure
"""
fig, axeslist = plt.subplots(ncols=ncols, nrows=nrows)
for ind,title in zip(range(len(figures)), figures):
axeslist.ravel()[ind].imshow(figures[title], cmap=plt.jet())
axeslist.ravel()[ind].set_title(title)
axeslist.ravel()[ind].set_axis_off()
plt.tight_layout() # optional
# generation of a dictionary of (title, images)
number_of_im = 20
w=10
h=10
figures = {'im'+str(i): np.random.randint(10, size=(h,w)) for i in range(number_of_im)}
# plot of the images in a figure, with 5 rows and 4 columns
plot_figures(figures, 5, 4)
plt.show()
However, this is basically just copy and paste from here: Multiple figures in a single window for which reason this post should be considered to be a duplicate.
I hope this helps.

It could be something like
var myvar = from a in context.MyEntity
join b in context.MyEntity2 on a.key equals b.key
select new { prop1 = a.prop1, prop2= b.prop1};
The parentheses capture particular strings for use by the backslashed numbers.
Here's another solution that could help with some of these use cases:
test-%:
$(PYTHON) run-tests.py $@
In other words, pick some prefix (test-
in this case), and then pass the target name directly to the program/runner. I guess this is mostly useful if there is some runner script involved that can unwrap the target name into something useful for the underlying program.
I make it work like a charm with this:
function HideLayer(theEvent){
var MyDiv=document.getElementById('MyDiv');
if(MyDiv==(!theEvent?window.event:theEvent.target)){
MyDiv.style.display='none';
}
}
Ah, and MyDiv
tag is like this:
<div id="MyDiv" onmouseout="JavaScript: HideLayer(event);">
<!-- Here whatever divs, inputs, links, images, anything you want... -->
<div>
This way, when onmouseout goes to a child, grand-child, etc... the style.display='none'
is not executed; but when onmouseout goes out of MyDiv it runs.
So no need to stop propagation, use timers, etc...
Thanks for examples, i could make this code from them.
Hope this helps someone.
Also can be improved like this:
function HideLayer(theLayer,theEvent){
if(theLayer==(!theEvent?window.event:theEvent.target)){
theLayer.style.display='none';
}
}
And then the DIVs tags like this:
<div onmouseout="JavaScript: HideLayer(this,event);">
<!-- Here whatever divs, inputs, links, images, anything you want... -->
<div>
So more general, not only for one div and no need to add id="..."
on each layer.
in your action performed method, call:
label1.setText(nameField.getText());
This way, when the button is clicked, label will be updated to the nameField text.
I found an additional way in which this problem occurs:
My LG phone's original OS was Froyo (Android 2.2) and was updated to ICS (Android 4.0.4).
But the Google Play Developers' Console shows that it detects my phone as a Froyo device.
(Google Play did not allow the app to be downloaded because of the false 'incompatibility', but it somehow still detects the installation.)
The phone's settings, in 'software', shows ICS V4.0.4. It seems that the Google Play server info for the phone is not updated to reflect the ICS update on the device. The app manifest minSDK is set to Honeycomb (3.0), so of course Google Play filters out the app.
Of addition interest:Below is code that I currently use to pull data from a MS SQL Server 2008 into VBA. You need to make sure you have the proper ADODB reference [VBA Editor->Tools->References] and make sure you have Microsoft ActiveX Data Objects 2.8 Library checked, which is the second from the bottom row that is checked (I'm using Excel 2010 on Windows 7; you might have a slightly different ActiveX version, but it will still begin with Microsoft ActiveX):
Sub Module for Connecting to MS SQL with Remote Host & Username/Password
Sub Download_Standard_BOM()
'Initializes variables
Dim cnn As New ADODB.Connection
Dim rst As New ADODB.Recordset
Dim ConnectionString As String
Dim StrQuery As String
'Setup the connection string for accessing MS SQL database
'Make sure to change:
'1: PASSWORD
'2: USERNAME
'3: REMOTE_IP_ADDRESS
'4: DATABASE
ConnectionString = "Provider=SQLOLEDB.1;Password=PASSWORD;Persist Security Info=True;User ID=USERNAME;Data Source=REMOTE_IP_ADDRESS;Use Procedure for Prepare=1;Auto Translate=True;Packet Size=4096;Use Encryption for Data=False;Tag with column collation when possible=False;Initial Catalog=DATABASE"
'Opens connection to the database
cnn.Open ConnectionString
'Timeout error in seconds for executing the entire query; this will run for 15 minutes before VBA timesout, but your database might timeout before this value
cnn.CommandTimeout = 900
'This is your actual MS SQL query that you need to run; you should check this query first using a more robust SQL editor (such as HeidiSQL) to ensure your query is valid
StrQuery = "SELECT TOP 10 * FROM tbl_table"
'Performs the actual query
rst.Open StrQuery, cnn
'Dumps all the results from the StrQuery into cell A2 of the first sheet in the active workbook
Sheets(1).Range("A2").CopyFromRecordset rst
End Sub

There is also read_csv
in Pandas, which is fast and supports non-comma column separators and automatic typing by column:
import pandas as pd
df = pd.read_csv('your_file',sep='\t')
It can be converted to a NumPy array if you prefer that type with:
import numpy as np
arr = np.array(df)
This is by far the easiest and most mature text import approach I've come across.
Note: This assumes that you will declare constants for row and column indexes named COLUMN_HEADING_ROW
, FIRST_COL
, and LAST_COL
, and that _xlSheet
is the name of the ExcelSheet
(using Microsoft.Interop.Excel
)
First, define the range:
var columnHeadingsRange = _xlSheet.Range[
_xlSheet.Cells[COLUMN_HEADING_ROW, FIRST_COL],
_xlSheet.Cells[COLUMN_HEADING_ROW, LAST_COL]];
Then, set the background color of that range:
columnHeadingsRange.Interior.Color = XlRgbColor.rgbSkyBlue;
Finally, set the font color:
columnHeadingsRange.Font.Color = XlRgbColor.rgbWhite;
And here's the code combined:
var columnHeadingsRange = _xlSheet.Range[
_xlSheet.Cells[COLUMN_HEADING_ROW, FIRST_COL],
_xlSheet.Cells[COLUMN_HEADING_ROW, LAST_COL]];
columnHeadingsRange.Interior.Color = XlRgbColor.rgbSkyBlue;
columnHeadingsRange.Font.Color = XlRgbColor.rgbWhite;
Like so:
def no(var):
"give var as a string (quote it like 'var')"
assert(var not in vars())
assert(var not in globals())
assert(var not in vars(__builtins__))
import keyword
assert(var not in keyword.kwlist)
Then later:
no('foo')
foo = ....
If your new variable foo
is not safe to use, you'll get an AssertionError
exception which will point to the line that failed, and then you will know better.
Here is the obvious contrived self-reference:
no('no')

The split work until 4000 chars depending on the characters that you are inserting. If you are inserting special characters it can fail. The only secure way is to declare a variable.
Stumbled across this answer and I actually wanted BOTH groups (data containing that one user and data containing everything but that one user). Not necessary for the specifics of this post, but I thought I would add in case someone was googling the same issue as me.

You mention "simple", but just in case anyone else is looking for something that meets more stringent security requirements, you might want to take a look at jpwgen. jpwgen is modeled after pwgen in Unix, and is very configurable.
Try this:
public interface UserRepository extends JpaRepository<User, Long> {
@Query(value = "SELECT * FROM USERS WHERE LASTNAME = ?1 ORDER BY /*#pageable*/",
countQuery = "SELECT count(*) FROM USERS WHERE LASTNAME = ?1",
nativeQuery = true)
Page<User> findByLastname(String lastname, Pageable pageable);
}

Options:
-h, --help show this help message and exit
-i INPUT, --input=INPUT
filename input (APK or android's binary xml)
-o OUTPUT, --output=OUTPUT

Yes, the syntax is accurate and it should be fine.
Here is the SQL Fiddle Demo I created for your particular case
create table sample2
(
id int primary key,
created_date date,
data varchar(10)
)
insert into sample2 values (1,'2012-01-01','testing');
And here is how to select the data
SELECT Created_Date
FROM sample2
WHERE Created_Date >= DATEADD(day,-11117, GETDATE())
Binary strings store raw-byte data, whilst character strings store text. Use binary data when storing hexi-decimal values such as SID
, GUID
and so on. The uniqueidentifier data type contains a globally unique identifier, or GUID. This
value is derived by using the NEWID() function to return a value that is unique to all objects. It's stored as a binary value but it is displayed as a character string.
Here is an example.
USE AdventureWorks2008R2;
GO
CREATE TABLE MyCcustomerTable
(
user_login varbinary(85) DEFAULT SUSER_SID()
,data_value varbinary(1)
);
GO
INSERT MyCustomerTable (data_value)
VALUES (0x4F);
GO
Applies to: SQL Server The following example creates the cust table with a uniqueidentifier data type, and uses NEWID to fill the table with a default value. In assigning the default value of NEWID(), each new and existing row has a unique value for the CustomerID column.
-- Creating a table using NEWID for uniqueidentifier data type.
CREATE TABLE cust
(
CustomerID uniqueidentifier NOT NULL
DEFAULT newid(),
Company varchar(30) NOT NULL,
ContactName varchar(60) NOT NULL,
Address varchar(30) NOT NULL,
City varchar(30) NOT NULL,
StateProvince varchar(10) NULL,
PostalCode varchar(10) NOT NULL,
CountryRegion varchar(20) NOT NULL,
Telephone varchar(15) NOT NULL,
Fax varchar(15) NULL
);
GO
-- Inserting 5 rows into cust table.
INSERT cust
(CustomerID, Company, ContactName, Address, City, StateProvince,
PostalCode, CountryRegion, Telephone, Fax)
VALUES

Hi first of all i would like you to use 'Synaptic Package Manager'. You just need to goto the ubuntu software center and search for synaptic package manager.. The beauty of this is that all the packages you need are easily available here. Second it will automatically configures all your paths. Now install this then search for opencv packages over there if you found the package with the green box then its installed but else the package is not in the right place so you need to reinstall it but from package manager this time. If installed then you can do this only, you just need to fill the OpenCV_DIR variable with the path of opencv (containing the OpenCVConfig.cmake file)
export OpenCV_DIR=<path_of_opencv>
if the project is not a big ,
1- change the name of folder project
2- make a new project with the same project (before renaming)
3- add existing files from the old project to the new project (totally same , same folders , same names , ...)
4- open the the new project file (as xml ) and the old project
5- copy the new project file (xml content ) and paste it in the old project file
6- delete the old project
7- rename the old folder project to old name
If you are using this in chrome/chromium browser(ex: in Ubuntu 14.04), You can use one of the below command to tackle this issue.
ThinkPad-T430:~$ google-chrome --allow-file-access-from-files
ThinkPad-T430:~$ google-chrome --allow-file-access-from-files fileName.html
ThinkPad-T430:~$ chromium-browser --allow-file-access-from-files
ThinkPad-T430:~$ chromium-browser --allow-file-access-from-files fileName.html
This will allow you to load the file in chrome or chromium. If you have to do the same operation for windows you can add this switch in properties of the chrome shortcut or run it from cmd
with the flag. This operation is not allowed in Chrome, Opera, Internet Explorer by default. By default it works only in firefox and safari. Hence using this command will help you.
Alternately you can also host it on any web server (Example:Tomcat-java,NodeJS-JS,Tornado-Python, etc) based on what language you are comfortable with. This will work from any browser.
First of all you should include ckeditor and jquery connector script in your page,
then create a textarea
<textarea name="content" class="editor" id="ms_editor"></textarea>
attach ckeditor to the text area, in my project I use something like this:
$('textarea.editor').ckeditor(function() {
}, { toolbar : [
['Cut','Copy','Paste','PasteText','PasteFromWord','-','Print', 'SpellChecker', 'Scayt'],
['Undo','Redo'],
['Bold','Italic','Underline','Strike','-','Subscript','Superscript'],
['NumberedList','BulletedList','-','Outdent','Indent','Blockquote'],
['JustifyLeft','JustifyCenter','JustifyRight','JustifyBlock'],
['Link','Unlink','Anchor', 'Image', 'Smiley'],
['Table','HorizontalRule','SpecialChar'],
['Styles','BGColor']
], toolbarCanCollapse:false, height: '300px', scayt_sLang: 'pt_PT', uiColor : '#EBEBEB' } );
on submit get the content using:
var content = $( 'textarea.editor' ).val();
That's it! :)
Use non-greedy matching, if your engine supports it. Add the ? inside the capture.

Swift 4 - 5.1 Protocol Extensions
public protocol NibInstantiatable {
static func nibName() -> String
}
extension NibInstantiatable {
static func nibName() -> String {
return String(describing: self)
}
}
extension NibInstantiatable where Self: UIView {
static func fromNib() -> Self {
let bundle = Bundle(for: self)
let nib = bundle.loadNibNamed(nibName(), owner: self, options: nil)
return nib!.first as! Self
}
}
Adoption
class MyView: UIView, NibInstantiatable {
}
This implementation assumes that the Nib has the same name as the UIView class. Ex. MyView.xib. You can modify this behavior by implementing nibName() in MyView to return a different name than the default protocol extension implementation.
In the xib the files owner is MyView and the root view class is MyView.
Usage
let view = MyView.fromNib()
For my case, none of other solutions worked. I had to do a backup of new modified files (shown with git status
), and run a git reset --hard
. This allowed me to realign with the remote server. Adding new modified files, and running
git add .
git commit -am "my comment"
git push
Did the trick. I hope this helps someone, as a "last chance" solution.
One way would be to inherit a new class,EntryWithSet
, and defining set
method that makes use of delete
and insert
methods of the Entry
class objects:
try: # In order to be able to import tkinter for
import tkinter as tk # either in python 2 or in python 3
except ImportError:
import Tkinter as tk
class EntryWithSet(tk.Entry):
"""
A subclass to Entry that has a set method for setting its text to
a given string, much like a Variable class.
"""
def __init__(self, master, *args, **kwargs):
tk.Entry.__init__(self, master, *args, **kwargs)
def set(self, text_string):
"""
Sets the object's text to text_string.
"""
self.delete('0', 'end')
self.insert('0', text_string)
def on_button_click():
import random, string
rand_str = ''.join(random.choice(string.ascii_letters) for _ in range(19))
entry.set(rand_str)
if __name__ == '__main__':
root = tk.Tk()
entry = EntryWithSet(root)
entry.pack()
tk.Button(root, text="Set", command=on_button_click).pack()
tk.mainloop()
Works even if the default value is a boolean value:
var setVariable = ( (b = 0) => b )( localStorage.getItem('value') );
If drv.Item("Quantity").Value < 5 Then
use this to like this
If Cint(drv.Item("Quantity").Value) < 5 Then
Send a SIGTERM or a SIGKILL to it:
http://en.wikipedia.org/wiki/SIGKILL
http://en.wikipedia.org/wiki/SIGTERM
SIGTERM is polite and lets the process clean up before it goes, whereas, SIGKILL is for when it won't listen >:)
Example from the shell (man page: http://unixhelp.ed.ac.uk/CGI/man-cgi?kill )
kill -9 pid
In C, you can do the same thing using the kill syscall:
kill(pid, SIGKILL);
See the following man page: http://linux.die.net/man/2/kill
For MAC users
After some research, this worked for me:
The current alternative for pluck()
is value()
.
Use a subquery in the where clause. For a delete query requirig a join, this example will delete rows that are unmatched in the joined table "docx_document" and that have a create date > 120 days in the "docs_documents" table.
delete from docs_documents d
where d.id in (
select a.id from docs_documents a
left join docx_document b on b.id = a.document_id
where b.id is null
and floor(sysdate - a.create_date) > 120
);
Which version of .NET are you using? If it's .NET 3.5, I'd just call ToArray()
and be done with it.
If you only have a non-generic IEnumerable, do something like this:
IEnumerable query = ...;
MyEntityType[] array = query.Cast<MyEntityType>().ToArray();
If you don't know the type within that method but the method's callers do know it, make the method generic and try this:
public static void T[] PerformQuery<T>()
{
IEnumerable query = ...;
T[] array = query.Cast<T>().ToArray();
return array;
}
First you need to create the config file, using cmd :
jupyter notebook --generate-config
Then, search for C:\Users\your_username\.jupyter folder (Search for that folder), and right click edit the jupyter_notebook_config.py.
Then, Ctrl+F: #c.NotebookApp.notebook_dir ='' . Note that the quotes are single quotes. Select your directory you want to have as home for your jupyter, and copy it with Ctrl+C, for example: C:\Users\username\Python Projects.
Then on that line, paste it like this : c.NotebookApp.notebook_dir = 'C:\\Users\\username\\Python Projects'
Make sure to remove #, as it is as comment.
Make sure to double slash \\ on each name of your path. Ctrl+S to save the config.py file !!!
Go back to your cmd and run jupyter notebook.
It should be in your directory of choice. Test it by making a folder and watch your directory from your computer.
For array of integer type, we need to change it to string type first and than use join function to get clean output without brackets.
arr = [1, 2, 3, 4, 5]
print(', '.join(map(str, arr)))
OUTPUT - 1, 2, 3, 4, 5
For array of string type, we need to use join function directly to get clean output without brackets.
arr = ["Ram", "Mohan", "Shyam", "Dilip", "Sohan"]
print(', '.join(arr)
OUTPUT - Ram, Mohan, Shyam, Dilip, Sohan
Assuming the original date is in cell A1:
=DATE(YEAR(A1), MONTH(A1), DAY(A1)-180)
The advantages of CXF:
The advantages of Axis2:
In Summary: From above advantage items, it brings us to a good thoughts to compare Axis2 and CXF on their own merits. they all have different well-developed areas in a certain field, CXF is very configurable, integratable and has rich tool kits supported and close to Java community, Axis2 has taken an approach that makes it in many ways resemble an application server in miniature. it is across multiple programming languages. because its Independence, Axis2 lends itself towards web services that stand alone, independent of other applications, and offers a wide variety of functionality.
As a developer, we need to accord our perspective to choose the right one, whichever framework you choose, you’ll have the benefit of an active and stable open source community. In terms of performance, I did a test based the same functionality and configed in the same web container, the result shows that CXF performed little bit better than Axis2, the single case may not exactly reflect their capabilities and performance.
In some research articles, it reveals that Axis2's proprietary ADB databinding is a bit faster than CXF since it don’t have additional feature(WS-Security). Apache AXIS2 is relatively most used framework but Apache CXF scores over other Web Services Framework comparatively considering ease of development, current industry trend, performance, overall scorecard and other features (unless there is Web Services Orchestration support is explicitly needed, which is not required here)

If you're currently on the branch you want to rename:
git branch -m new_name
Or else:
git branch -m old_name new_name
You can check with:
git branch -a
As you can see, only the local name changed Now, to change the name also in the remote you must do:
git push origin :old_name
This removes the branch, then upload it with the new name:
git push origin new_name
In some cases, I'd like kill processes simutaneously like this way:

But, I think it is a little bit inappropriate in your case.(May be there are running python a, python b, python x...in the background.)
Try with an API lvl 28 emulator (Android 9). I was trying with api lvl 29 and kept getting errors.

What would you like these support libraries to do? Just using OpenGL from C# is simple enough and does not require any additional libraries afaik.
Just set an onload function on the body:
<body onload="init()">
Then do something like this in javascript:
function init() {
var someimage = 'changableBackgroudImage';
document.body.style.background = 'url(img/'+someimage+'.png) no-repeat center center'
}
You can change the 'someimage' variable to whatever you want depending on some conditions, such as the time of day or something, and that image will be set as the background image.

this works fine, but file name does not display anymore.

All you need is a control that you can set the text of, and an UpdatePanel if the exception occurs during a postback.
If occurs during a postback: markup:
<ajax:UpdatePanel id="ErrorUpdatePanel" runat="server" UpdateMode="Coditional">
<ContentTemplate>
<asp:TextBox id="ErrorTextBox" runat="server" />
</ContentTemplate>
</ajax:UpdatePanel>
code:
try
{
do something
}
catch(YourException ex)
{
this.ErrorTextBox.Text = ex.Message;
this.ErrorUpdatePanel.Update();
}
It is a bit too late, but here is a functional style of checking:
Optional.ofNullable(str)
.filter(s -> !(s.trim().isEmpty()))
.ifPresent(result -> {
// your query setup goes here
});
I was looking for a inline editing solution and I found a plunker that seemed promising, but it didn't work for me out of the box. After some tinkering with the code I got it working. Kudos to the person who made the initial effort to code this piece.
The example is available here http://plnkr.co/edit/EsW7mV?p=preview
Here goes the code:
app.controller('MainCtrl', function($scope) {
$scope.updateTodo = function(indx) {
console.log(indx);
};
$scope.cancelEdit = function(value) {
console.log('Canceled editing', value);
};
$scope.todos = [
{id:123, title: 'Lord of the things'},
{id:321, title: 'Hoovering heights'},
{id:231, title: 'Watership brown'}
];
});
// On esc event
app.directive('onEsc', function() {
return function(scope, elm, attr) {
elm.bind('keydown', function(e) {
if (e.keyCode === 27) {
scope.$apply(attr.onEsc);
}
});
};
});
// On enter event
app.directive('onEnter', function() {
return function(scope, elm, attr) {
elm.bind('keypress', function(e) {
if (e.keyCode === 13) {
scope.$apply(attr.onEnter);
}
});
};
});
// Inline edit directive
app.directive('inlineEdit', function($timeout) {
return {
scope: {
model: '=inlineEdit',
handleSave: '&onSave',
handleCancel: '&onCancel'
},
link: function(scope, elm, attr) {
var previousValue;
scope.edit = function() {
scope.editMode = true;
previousValue = scope.model;
$timeout(function() {
elm.find('input')[0].focus();
}, 0, false);
};
scope.save = function() {
scope.editMode = false;
scope.handleSave({value: scope.model});
};
scope.cancel = function() {
scope.editMode = false;
scope.model = previousValue;
scope.handleCancel({value: scope.model});
};
},
templateUrl: 'inline-edit.html'
};
});
Directive template:
<div>
<input type="text" on-enter="save()" on-esc="cancel()" ng-model="model" ng-show="editMode">
<button ng-click="cancel()" ng-show="editMode">cancel</button>
<button ng-click="save()" ng-show="editMode">save</button>
<span ng-mouseenter="showEdit = true" ng-mouseleave="showEdit = false">
<span ng-hide="editMode" ng-click="edit()">{{model}}</span>
<a ng-show="showEdit" ng-click="edit()">edit</a>
</span>
</div>
To use it just add water:
<div ng-repeat="todo in todos"
inline-edit="todo.title"
on-save="updateTodo($index)"
on-cancel="cancelEdit(todo.title)"></div>
UPDATE:
Another option is to use the readymade Xeditable for AngularJS:
Change the checkboxes so that the name includes the index inside the brackets:
<input type="checkbox" class="checkbox_veh" id="checkbox_addveh<?php echo $i; ?>" <?php if ($vehicle_feature[$i]->check) echo "checked"; ?> name="feature[<?php echo $i; ?>]" value="<?php echo $vehicle_feature[$i]->id; ?>">
The checkboxes that aren't checked are never submitted. The boxes that are checked get submitted, but they get numbered consecutively from 0, and won't have the same indexes as the other corresponding input fields.
Sometimes you need to work with adjustments.
Don't use cast to long! Use nanoadjustment.
For example, using Oanda Java API for trading you can get datetime as UNIX format.
For example: 1592523410.590566943
System.out.println("instant with nano = " + Instant.ofEpochSecond(1592523410, 590566943));
System.out.println("instant = " + Instant.ofEpochSecond(1592523410));
you get:
instant with nano = 2020-06-18T23:36:50.590566943Z
instant = 2020-06-18T23:36:50Z
Also, use:
Date date = Date.from( Instant.ofEpochSecond(1592523410, 590566943) );
My work uses Winnovative's PDF generator (We've used it mainly to convert HTML to PDF, but you can generate it other ways as well)
Try this:
import cv2
import cv
color_img = cv2.cvtColor(gray_img, cv.CV_GRAY2RGB)
I discovered, while using opencv, that some of the constants are defined in the cv2 module, and other in the cv module.
Just had this problem with visual studio being unable to find my tests, couldn't see the button to run them besides the method, and they weren't picked up by running all tests in the project.
Turns out my test class wasn't public! Making it public allowed VS to discover the tests.
The magic number comes from UNIX-type systems where the first few bytes of a file held a marker indicating the file type.
This error indicates you are trying to load a non-valid file type into R. For some reason, R no longer recognizes this file as an R workspace file.
The fastest way is to "maybe decode" the possible JSON string
If you want to decode complex objects or larger arrays, this is the fastest way, by far!
If your json string contains short values (like scalars or objects with only 1-2 attributes) then all solutions in this SO questions come to a similar performance.
Here is a performance comparison that I've done with some dummy and real-live JSON values:
PHP version: 7.4.12
1 | Duration: 1.5828 sec | 60,000 calls | json_last_error() == JSON_ERROR_NONE
2 | Duration: 1.5202 sec | 60,000 calls | is_object( json_decode() )
3 | Duration: 1.5400 sec | 60,000 calls | json_decode() && $res != $string
4 | Duration: 1.3536 sec | 60,000 calls | preg_match()
5 | Duration: 0.2261 sec | 60,000 calls | "maybe decode" approach
The last line is the code from this answer, which is the "maybe decode" approach.
Here is the performance comparison script, there you can see the test-data I used for the comparison: https://gist.github.com/stracker-phil/6a80e6faedea8dab090b4bf6668ee461
We first perform some type checks and string comparisons before attempting to decode the JSON string. This gives us the best performance because json_decode() can be slow.
/**
* Returns true, when the given parameter is a valid JSON string.
*/
function is_json( $value ) {
// A non-string value can never be a JSON string.
if ( ! is_string( $value ) ) { return false; }
// Numeric strings are always valid JSON.
if ( is_numeric( $value ) ) { return true; }
// Any non-numeric JSON string must be longer than 2 characters.
if ( strlen( $value ) < 2 ) { return false; }
// "null" is valid JSON string.
if ( 'null' === $value ) { return true; }
// "true" and "false" are valid JSON strings.
if ( 'true' === $value ) { return true; }
if ( 'false' === $value ) { return false; }
// Any other JSON string has to be wrapped in {}, [] or "".
if ( '{' != $value[0] && '[' != $value[0] && '"' != $value[0] ) { return false; }
// Note the last param (1), this limits the depth to the first level.
$json_data = json_decode( $value, null, 1 );
// When json_decode fails, it returns NULL.
if ( is_null( $json_data ) ) { return false; }
return true;
}
This function uses the same logic but either returns the decoded JSON object or the original value.
I use this function in a parser that recursively decodes a complex object. Some attributes might be decoded already by an earlier iteration. That function recognizes this and does not attempt to double decode the value again.
/**
* Tests, if the given $value parameter is a JSON string.
* When it is a valid JSON value, the decoded value is returned.
* When the value is no JSON value (i.e. it was decoded already), then
* the original value is returned.
*/
function get_data( $value, $as_object = false ) {
if ( ! is_string( $value ) ) { return $value; }
if ( is_numeric( $value ) ) { return 0 + $value; }
if ( strlen( $value ) < 2 ) { return $value; }
if ( 'null' === $value ) { return null; }
if ( 'true' === $value ) { return true; }
if ( 'false' === $value ) { return false; }
if ( '{' != $value[0] && '[' != $value[0] && '"' != $value[0] ) { return $value; }
$json_data = json_decode( $value, $as_object );
if ( is_null( $json_data ) ) { return $value; }
return $json_data;
}
Note: When passing a non-string to any other solution in this SO question, you will get dramatically degraded performance + wrong return values (or even fatal errors). This code is bulletproof and highly performant.
Thinking a little bit outside the box here I'm going to propose that powershell may be an answer on up-to-date XP/2003 machines and certainly on Vista/2008 and newer (instead of .bat/.cmd). Anyone who has some Perl in their background should feel at-home pretty quickly.
$serviceName = "ServiceName";
$serviceStatus = (get-service "$serviceName").Status;
if ($serviceStatus -eq "Running") {
echo "Service is Running";
}
else {
#Could be Stopped, Stopping, Paused, or even Starting...
echo "Service is $serviceStatus";
}
Another way, if you have significant investment in batch is to run the PS script as a one-liner, returning an exit code.
@ECHO off
SET PS=powershell -nologo -command
%PS% "& {if((get-service SvcName).Status -eq 'Running'){exit 1}}"
ECHO.%ERRORLEVEL%
Running as a one-liner also gets around the default PS code signing policy at the expense of messiness. To put the PS commands in a .ps1 file and run like powershell myCode.ps1
you may find signing your powershell scripts is neccessary to run them in an automated way (depends on your environment). See http://www.hanselman.com/blog/SigningPowerShellScripts.aspx for details
At first, you must specify your path, the path that your *.csv
files are in there
path = 'f:\project\dataset'
You can change it based on your system.
then,
use dir
function :
files = dir (strcat(path,'\*.csv'))
L = length (files);
for i=1:L
image{i}=csvread(strcat(path,'\',file(i).name));
% process the image in here
end
pwd
also can be used.
Below is a class which will accomplish the very basics of what you want to do when reading data from a MySQL database into a JTable
in Java.
import java.awt.*;

String userid = "root";
String password = "sesame";
String sql = "SELECT * FROM animals";
// Java SE 7 has try-with-resources
// This will ensure that the sql objects are closed when the program
// is finished with them
try (Connection connection = DriverManager.getConnection( url, userid, password );
Statement stmt = connection.createStatement();
ResultSet rs = stmt.executeQuery( sql ))
{
ResultSetMetaData md = rs.getMetaData();
int columns = md.getColumnCount();
// Get column names
for (int i = 1; i <= columns; i++)
{
columnNames.add( md.getColumnName(i) );
}
// Get row data
while (rs.next())
{
ArrayList row = new ArrayList(columns);
for (int i = 1; i <= columns; i++)
{
row.add( rs.getObject(i) );
}
data.add( row );
}
}
catch (SQLException e)
{
System.out.println( e.getMessage() );
}
// Create Vectors and copy over elements from ArrayLists to them
// Vector is deprecated but I am using them in this example to keep

for (int i = 0; i < data.size(); i++)
{
ArrayList subArray = (ArrayList)data.get(i);

{
subVector.add(subArray.get(j));
}
dataVector.add(subVector);
}
for (int i = 0; i < columnNames.size(); i++ )
columnNamesVector.add(columnNames.get(i));
// Create table with database data
JTable table = new JTable(dataVector, columnNamesVector)

In the NetBeans IDE which you are using - you will need to add the MySQL JDBC Driver in Project Properties as I display here:
Otherwise the code will throw an SQLException
stating that the driver cannot be found.
Now in my example, yourdb
is the name of the database and animals
is the name of the table that I am performing a query against.
Here is what will be output:
Parting note:
You stated that you were a novice and needed some help understanding some of the basic classes and concepts of Java. I will list a few here, but remember you can always browse the docs on Oracle's site.
The following are the 5 steps required:
You can find the step by step VC++ IDE screen shot at http://www.softwareandfinance.com/Visual_CPP/DLLDynamicBinding.html
Here is the code snippet:
int main()
{
/***
__declspec(dllimport) bool GetWelcomeMessage(char *buf, int len); // used for static binding
***/
typedef bool (*GW)(char *buf, int len);
HMODULE hModule = LoadLibrary(TEXT("TestServer.DLL"));
GW GetWelcomeMessage = (GW) GetProcAddress(hModule, "GetWelcomeMessage");
char buf[128];
if(GetWelcomeMessage(buf, 128) == true)
std::cout << buf;
return 0;
}
You can put a second element inside the element you wish to have a transparent background on.
<div class="container">
<div class="container-background"></div>
<div class="content">
Yay, happy content!
</div>
</div>
Then make the '.container-background' positioned absolutely to cover the parent element. At this point you'll be able to adjust the opacity of it without affecting the opacity of the content inside '.container'.
.container {
position: relative;
}
.container .container-background {
position: absolute;
top: 0;
right: 0;
bottom: 0;
left: 0;
background: url(background.png);
opacity: 0.5;
}
.container .content {
position: relative;
z-index: 1;
}
You should configure the sonar-runner to use your existing SonarQube server. To do so, you need to update its conf/sonar-runner.properties
file and specify the SonarQube server URL, username, password, and JDBC URL as well. See https://docs.sonarqube.org/display/SCAN/Analyzing+with+SonarQube+Scanner for details.
If you don't yet have an up and running SonarQube server, then you can launch one locally (with the default configuration) - it will bind to http://localhost:9000 and work with the default sonar-runner configuration. See https://docs.sonarqube.org/latest/setup/get-started-2-minutes/ for details on how to get started with the SonarQube server.
try this :
string getValue = Convert.ToString(cmd.ExecuteScalar());
I am adding my solution to this problem.
I don't want to use image and validator will punish you for using negative values in CSS, so I go this way:
ul { list-style:none; padding:0; margin:0; }
li { padding-left:0.75em; position:relative; }
li:before { content:"•"; color:#e60000; position:absolute; left:0em; }
in Firefox 39 I've found that setting a border to the select element will render the arrow as (2). No border set, will render the arrow as (1). I think it's a bug.
Unfortunately, it is not possible to "get" the height of an element via CSS because CSS is not a language that returns any sort of data other than rules for the browser to adjust its styling.
Your resolution can be achieved with jQuery, or alternatively, you can fake it with CSS3's transform:translateY();
rule.
If we assume that your target div in this instance is 200px high - this would mean that you want the div to have a margin of 190px?
This can be achieved by using the following CSS:
.dynamic-height {
-webkit-transform: translateY(100%); //if your div is 200px, this will move it down by 200px, if it is 100px it will down by 100px etc
transform: translateY(100%); //if your div is 200px, this will move it down by 200px, if it is 100px it will down by 100px etc
margin-top: -10px;
}
In this instance, it is important to remember that translateY(100%)
will move the element in question downwards by a total of it's own length.
The problem with this route is that it will not push element below it out of the way, where a margin would.
If faking it isn't going to work for you, then your next best bet would be to implement a jQuery script to add the correct CSS for you.
jQuery(document).ready(function($){ //wait for the document to load
$('.dynamic-height').each(function(){ //loop through each element with the .dynamic-height class
$(this).css({
'margin-top' : $(this).outerHeight() - 10 + 'px' //adjust the css rule for margin-top to equal the element height - 10px and add the measurement unit "px" for valid CSS
});
});
});
For fun, I wrote a little jQuery add-on method that will check for any one of multiple class names:
$.fn.hasAnyClass = function() {
for (var i = 0; i < arguments.length; i++) {
if (this.hasClass(arguments[i])) {
return true;
}
}
return false;
}
Then, in your example, you could use this:
if ($('html').hasAnyClass('m320', 'm768')) {
// do stuff
}
You can pass as many class names as you want.
Here's an enhanced version that also lets you pass multiple class names separated by a space:
$.fn.hasAnyClass = function() {
for (var i = 0; i < arguments.length; i++) {
var classes = arguments[i].split(" ");
for (var j = 0; j < classes.length; j++) {
if (this.hasClass(classes[j])) {
return true;
}
}
}
return false;
}
if ($('html').hasAnyClass('m320 m768')) {
// do stuff
}
Working demo: http://jsfiddle.net/jfriend00/uvtSA/
Use display instead of visibility. display: none for invisible and no setting for visible.
I had a similar problem when I had installed the 12c database as per Oracle's tutorial . The instruction instructs reader to create a PLUGGABLE DATABASE (pdb).
sqlplus hr/hr@pdborcl
would result in ORACLE initialization or shutdown in progress
.
Login as SYSDBA
to the dabase :
sqlplus SYS/Oracle_1@pdborcl AS SYSDBA
Alter database:
alter pluggable database pdborcl open read write;
Login again:
sqlplus hr/hr@pdborcl
That worked for me

From: http://webdev.issimplified.com/2010/03/02/mysql-on-windows-force-table-names-to-lowercase/
An old school solution like:
double X=((double)rand()/(double)RAND_MAX);
Should meet all your criteria (portable, standard and fast). obviously the random number generated has to be seeded the standard procedure is something like:
srand((unsigned)time(NULL));
An <input type=hidden>
element is not a hidden input box. It is simply a form field that has a value set via markup or via scripting, not via user input. You can use it for multi-line data too, e.g.
<input type=hidden name=stuff value=
"Hello
world, how
are you?">
If the value contains the Ascii quotation mark ("), then, as for any HTML attribute, you need to use Ascii apostrophes (') as attribute value delimites or escape the quote as "
, e.g.
<input type=hidden name=stuff value="A "funny" example">
One gotcha is that the following is implementation dependent (according to the ANSI standard):
char x = -1;
x >> 1;
x can now be 127 (01111111) or still -1 (11111111).
In practice, it's usually the latter.
I would suggest you just write a function to do what you're saying probably using drop
(to delete columns) and insert
to insert columns at a position. There isn't an existing API function to do what you're describing.
Building on top of Mike Causer's answer I've made this function which takes into consideration multiple params with the same key (foo=bar&foo=baz
) and also comma-separated parameters (foo=bar,baz,bin
). It also lets you search for a certain query key.
function getQueryParams(queryKey) {
var queryString = window.location.search;
var query = {};
var pairs = (queryString[0] === '?' ? queryString.substr(1) : queryString).split('&');
for (var i = 0; i < pairs.length; i++) {
var pair = pairs[i].split('=');
var key = decodeURIComponent(pair[0]);
var value = decodeURIComponent(pair[1] || '');
// Se possui uma vírgula no valor, converter em um array
value = (value.indexOf(',') === -1 ? value : value.split(','));
// Se a key já existe, tratar ela como um array
if (query[key]) {
if (query[key].constructor === Array) {
// Array.concat() faz merge se o valor inserido for um array
query[key] = query[key].concat(value);
} else {
// Se não for um array, criar um array contendo o valor anterior e o novo valor
query[key] = [query[key], value];
}
} else {
query[key] = value;
}
}
if (typeof queryKey === 'undefined') {
return query;
} else {
return query[queryKey];
}
}
Example input:
foo.html?foo=bar&foo=baz&foo=bez,boz,buz&bar=1,2,3
Example output
{
foo: ["bar","baz","bez","boz","buz"],
bar: ["1","2","3"]
}
Don't just link to the line numbers! Be sure to use the canonical URL too. Otherwise when that file is updated, you'll have a URL that points to the wrong lines!
How to make a permanent link to the right lines:
Click on the line number you want (like line 18), and the URL in your browser will get a #L18
tacked onto the end. You literally click on the 18
at the left side, not the line of code. Looks like this:
And now your browser's URL looks like this:
https://github.com/git/git/blob/master/README#L18
If you want multiple lines selected, simply hold down the shift key and click a second line number, like line 20. Looks like this:
And now your browser's URL looks like this:
https://github.com/git/git/blob/master/README#L18-L20
Here's the important part:
Now get the canonical url for that particular commit by pressing the y
key. The URL in your browser will change to become something like this:
https://github.com/git/git/blob/5bdb7a78adf2a2656a1915e6fa656aecb45c1fc3/README#L18-L20
That link contains the actual SHA hash for that particular commit, rather than the current version of the file on master
. That means that this link will work forever and not point to lines 18-20 of whatever future version of that file might contain.
Now bask in the glow of your new permanent link. ;-)
update 9/29/2017: As pointed out by @watashiSHUN, github has now made it easier to get the permanent link by providing a ...
menu on the left after you select one or more lines. Please upvote @watashiSHUN's answer too.
update 3/25/2016: Case in point — in the example above, I referred to the "README" file in the URL. Those non-canonical urls actually worked when this answer was written. But now those urls no longer work since README
was moved to README.md
. But the canonical URL with SHA hash still works, just as expected.
versionCode
A positive integer used as an internal version number. This number is used only to determine whether one version is more recent than another, with higher numbers indicating more recent versions. This is not the version number shown to users; that number is set by the versionName
setting, below. The Android system uses the versionCode
value to protect against downgrades by preventing users from installing an APK with a lower versionCode
than the version currently installed on their device.
The value is a positive integer so that other apps can programmatically evaluate it, for example to check an upgrade or downgrade relationship. You can set the value to any positive integer you want, however you should make sure that each successive release of your app uses a greater value. You cannot upload an APK to the Play Store with a versionCode
you have already used for a previous version.
versionName
A string used as the version number shown to users. This setting can be specified as a raw string or as a reference to a string resource.
The value is a string so that you can describe the app version as a .. string, or as any other type of absolute or relative version identifier. The versionName
has no purpose other than to be displayed to users.
There's also the function tags, a bit more flexible:
<%@ taglib uri="http://java.sun.com/jsp/jstl/functions" prefix="fn" %>
<c:if test="${fn:length(list) > 0}">
And here's the tag documentation.
I'm a little bit late to this party but seems that nobody actually wrote all use cases. So...

It isn't a comment.
Especially in Visual Studio Code, these words baffle PSScriptAnalyzer.
You could actively break your session in VS Code.
Store the Thread-objects into some collection (like a List or a Set), then loop through the collection once the threads are started and call join() on the Threads.
@Vilmantas Baranauskas: Regarding this answer, I would comment if I had the rep points, but I don't. I wanted to note that the Counter class defined there is NOT thread-safe as it is not sufficient to just synchronize inc() without synchronizing value(). Other threads calling value() are not guaranteed to see the the value unless a happens-before relationship has been established with the update.
Given a Window object myWindow, myWindow.Show() will open it modelessly and myWindow.ShowDialog() will open it modally. However, even the latter doesn't block, from what I remember.
Default value for parameters are evaluated at "compilation", once. So obviously you can't access self
. The classic example is list
as default parameter. If you add elements into it, the default value for the parameter changes!
The workaround is to use another default parameter, typically None
, and then check and update the variable.
Ken Thompson is right! - for me also this way works (excel 2016), but type definition GUID_TYPE is skipped, so full scripting is:
Private Type GUID_TYPE
Data1 As Long
Data2 As Integer
Data3 As Integer
Data4(7) As Byte
End Type
Private Declare PtrSafe Function CoCreateGuid Lib "ole32.dll" (Guid As GUID_TYPE) As LongPtr
Private Declare PtrSafe Function StringFromGUID2 Lib "ole32.dll" (Guid As GUID_TYPE, ByVal lpStrGuid As LongPtr, ByVal cbMax As Long) As LongPtr
Function CreateGuidString(Optional IncludeHyphens As Boolean = True, Optional IncludeBraces As Boolean = False)
Dim Guid As GUID_TYPE
Dim strGuid As String
Dim retValue As LongPtr
Const guidLength As Long = 39 'registry GUID format with null terminator {xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}
retValue = CoCreateGuid(Guid)
If retValue = 0 Then
strGuid = String$(guidLength, vbNullChar)
retValue = StringFromGUID2(Guid, StrPtr(strGuid), guidLength)
If retValue = guidLength Then
' valid GUID as a string
' remove them from the GUID
If Not IncludeHyphens Then
strGuid = Replace(strGuid, "-", vbNullString, Compare:=vbTextCompare)
End If
' If IncludeBraces is switched from the default False to True,
' leave those curly braces be!
If Not IncludeBraces Then
strGuid = Replace(strGuid, "{", vbNullString, Compare:=vbTextCompare)
strGuid = Replace(strGuid, "}", vbNullString, Compare:=vbTextCompare)
End If
CreateGuidString = strGuid
End If
End If
End Function
Not exactly the answer to the question, but I needed to scroll down as soon as an EditText got the focus. However the accepted answer would make the ET also lose focus right away (to the ScrollView I assume).
My workaround was the following:
emailEt.setOnFocusChangeListener(new View.OnFocusChangeListener() {
@Override
public void onFocusChange(View v, boolean hasFocus) {
if(hasFocus){
Toast.makeText(getActivity(), "got the focus", Toast.LENGTH_LONG).show();
scrollView.postDelayed(new Runnable() {
@Override
public void run() {
scrollView.fullScroll(ScrollView.FOCUS_DOWN);
}
}, 200);
}else {
Toast.makeText(getActivity(), "lost the focus", Toast.LENGTH_LONG).show();
}
}
});
To get started with dotnet core, SqlServer and EF core the below DBContextOptionsBuilder would sufice and you do not need to create App.config file. Do not forget to change the sever address and database name in the below code.
protected override void OnConfiguring(DbContextOptionsBuilder options)
=> options.UseSqlServer(@"Server=(localdb)\MSSQLLocalDB;Database=TestDB;Trusted_Connection=True;");
To use the EF core SqlServer provider and compile the above code install the EF SqlServer package
dotnet add package Microsoft.EntityFrameworkCore.SqlServer
After compilation before running the code do the following for the first time
dotnet tool install --global dotnet-ef
dotnet add package Microsoft.EntityFrameworkCore.Design
dotnet ef migrations add InitialCreate
dotnet ef database update
To run the code
dotnet run
This means that Table A can have one or more records relating to a single record in Table B.
If you already have the tables in place, use the ALTER TABLE statement to create the foreign key constraint:
ALTER TABLE A ADD CONSTRAINT fk_b FOREIGN KEY (b_id) references b(id)
fk_b
: Name of the foreign key constraint, must be unique to the databaseb_id
: Name of column in Table A you are creating the foreign key relationship onb
: Name of table, in this case bid
: Name of column in Table BI have used sudo, but it didnt solve the problem, I have fixed the issue by changing the node_modules folder permission,
sudo chmod -R 777 node_modules
If you want you can replace 777 with any other code if you dont set the permission for all user/group.
I am assuming you know the length of the part before the _
and after the underscore, as well as the extension. If you don't it might be more complex than a simple substring.
cd C:\path\to\the\files
for /f %%a IN ('dir /b *.jpg') do (
set p=%a:~0,3%
set q=%a:~4,4%
set b=%p_%q.jpg
ren %a %b
)
I just came up with this script, and I did not test it. Check out this and that for more info.
IF you want to assume you don't know the positions of the _
and the lengths and the extension, I think you could do something with for loops to check the index of the _
, then the last index of the .
, wrap it in a goto
thing and make it work. If you're willing to go through that trouble, I'd suggest you use WindowsPowerShell (or Cygwin) at least (for your own sake) or install a more advanced scripting language (think Python/Perl) you'll get more support either way.
$sql = "SELECT * FROM MY_TABLE";
$result = mysqli_query($conn, $sql); // First parameter is just return of "mysqli_connect()" function
echo "<br>";
echo "<table border='1'>";
while ($row = mysqli_fetch_assoc($result)) { // Important line !!! Check summary get row on array ..
echo "<tr>";
foreach ($row as $field => $value) { // I you want you can right this line like this: foreach($row as $value) {
echo "<td>" . $value . "</td>"; // I just did not use "htmlspecialchars()" function.
}
echo "</tr>";
}
echo "</table>";
I think you're using the wrong approach. You should set the value
attribute of your input elements. Check the docs for .val() for examples of setting and returning the .val() of input elements.
ie.
<input type="radio" runat="server" name="testGroup" value="test2" />
return $('input:radio[name=testGroup]:checked').val() == 'test2';
If you create a new database it's good to create user with permissions only for this database (if anything goes wrong you won't compromise root user login and password). So everything together will look like this:
mysql -u base_user -pbase_user_pass -e "create database new_db; GRANT ALL PRIVILEGES ON new_db.* TO new_db_user@localhost IDENTIFIED BY 'new_db_user_pass'"
Where:
base_user is the name for user with all privileges (probably the root)
base_user_pass it's the password for base_user (lack of space between -p and base_user_pass is important)
new_db is name for newly created database
new_db_user is name for the new user with access only for new_db
new_db_user_pass it's the password for new_db_user
The problem may be with jquery selector you've chosen
$("video")
is not a selector
The right selector may be putting an id element for video tag i.e.
Let's say your video element looks like this:
<video id="vid1" width="480" height="267" oster="example.jpg" durationHint="33">
<source src="video1.ogv" />
<source src="video2.ogv" />
</video>
Then you can select it via $("#vid1")
with hash mark (#), id selector in jquery.
If a video element is exposed in function,then you have access to HtmlVideoElement (HtmlMediaElement).This elements has control over video element,in your case you can use pause()
method for your video element.
Check reference for VideoElement here.
Also check that there is a fallback reference here.
You can use the findIndex method with a callback function and its "this" parameter.
Note: old browsers don't know findIndex but a polyfill is available.
Sample code (take care that in the original question, a new object is pushed only if neither of its data is in previoulsy pushed objects):
var a=[{name:"tom", text:"tasty"}], b;
var magic=function(e) {
return ((e.name == this.name) || (e.text == this.text));
};
b={name:"tom", text:"tasty"};
if (a.findIndex(magic,b) == -1)
a.push(b); // nothing done
b={name:"tom", text:"ugly"};
if (a.findIndex(magic,b) == -1)
a.push(b); // nothing done
b={name:"bob", text:"tasty"};
if (a.findIndex(magic,b) == -1)
a.push(b); // nothing done
b={name:"bob", text:"ugly"};
if (a.findIndex(magic,b) == -1)
a.push(b); // b is pushed into a
Even though its not directly related. But I found that the CALC code won't work if you do not put spaces properly.
So this did not work for me calc(#{$a}+7px)
But this worked calc(#{$a} + 7px)
Took me sometime to figure this out.
The following workaround does not use the PRINT
statement. It works well in combination with the SQL Server Management Studio.
SELECT CAST('<root><![CDATA[' + @MyLongString + ']]></root>' AS XML)
You can click on the returned XML to expand it in the built-in XML viewer.
There is a pretty generous client side limit on the displayed size. Go to Tools/Options/Query Results/SQL Server/Results to Grid/XML data
to adjust it if needed.
No. JavaScript is automatically garbage collected; the object's memory will be reclaimed only if the GC decides to run and the object is eligible for collection.
Seeing as that will happen automatically as required, what would be the purpose of reclaiming the memory explicitly?
Returning the whole object on an update would not seem very relevant, but I can hardly see why returning the whole object when it is created would be a bad practice in a normal use case. This would be useful at least to get the ID easily and to get the timestamps when relevant. This is actually the default behavior got when scaffolding with Rails.
I really do not see any advantage to returning only the ID and doing a GET request after, to get the data you could have got with your initial POST.
Anyway as long as your API is consistent I think that you should choose the pattern that fits your needs the best. There is not any correct way of how to build a REST API, imo.
Did you try turning off DEP (Data Execution Prevention) for your application ?
I think many of the answers here may be missing a quality method included in StringBuilder
: .delete(int start, [int] end)
. I know this is a late reply; however, this should be made known (and explained a bit more thoroughly).
Let's say you have a StringBuilder table - which you wish to modify, dynamically, throughout your program (one I am working on right now does this), e.g.
StringBuilder table = new StringBuilder();
If you are looping through the method and alter the content, use the content, then wish to discard the content to "clean up" the StringBuilder
for the next iteration, you can delete it's contents, e.g.
table.delete(int start, int end).
start and end being the indices of the chars you wish to remove. Don't know the length in chars and want to delete the whole thing?
table.delete(0, table.length());
NOW, for the kicker. StringBuilders
, as mentioned previously, take a lot of overhead when altered frequently (and can cause safety issues with regard to threading); therefore, use StringBuffer
- same as StringBuilder
(with a few exceptions) - if your StringBuilder
is used for the purpose of interfacing with the user.
Kind of old question, but with the latest XCode, codesign
is easy:
$ codesign -s my_certificate example.ipa
$ codesign -vv example.ipa
example.ipa: valid on disk
example.ipa: satisfies its Designated Requirement
<form onSubmit={(e) => {this.doSomething(); e.preventDefault();}}></form>
it work fine for me
