Seems like the general query log is the file that you need. A good introduction to this is at http://dev.mysql.com/doc/refman/5.1/en/query-log.html
The Simplest way to do this is:
$("#Instrument").data('kendoDropDownList').value("A value");
Here is the JSFiddle example.
I went through the same issue recently while installing mysql on mac os x capitan. I did not find the correct answer here, so adding this answer.
MySql in current versions, generates a temporary password when you install mysql. Use this password to set a new password using the mysqladmin utility as below;
/usr/local/mysql/bin/mysqladmin -u root -p'<your temp password>' password '<your new password>'
Hope it helps you and others.
If using Apache Commons Codec is an option, then this would be a shorter implementation:
String md5Hex = new String(Hex.encodeHex(DigestUtils.md5(data)));
Or SHA:
String shaHex= new String(Hex.encodeHex(DigestUtils.sha("textToHash")));
Source for above.

Chaquopy is a plugin for Android Studio's Gradle-based build system. It focuses on close integration with the standard Android development tools.
It provides complete APIs to call Java from Python or Python from Java, allowing the developer to use whichever language is best for each component of their app.
It can automatically download PyPI packages and build them into an app, including selected native packages such as NumPy.
It enables full access to all Android APIs from Python, including the native user interface toolkit (example pure-Python activity).
This is a commercial product, but it's free for open-source use and will always remain that way.
(I am the creator of this product.)
I think <src>
adds some resources to the page and <href>
is just for providing a link to a resource(without adding the resource itself to the page).
This worked for me on Debian stretch

service apache2 restart

It is a bad idea to select * from anything, period. This is why SSMS adds every field name, even if there are hundreds, instead of select *. It is extremely inefficient regardless of how large the table is. If you don't know what the fields are, its still more efficient to pull them out of the INFORMATION_SCHEMA database than it is to select *.
A better query would be:
SELECT
COLUMN_NAME,
Case
When DATA_TYPE In ('varchar', 'char', 'nchar', 'nvarchar', 'binary')
Then convert(varchar(MAX), CHARACTER_MAXIMUM_LENGTH)
When DATA_TYPE In ('numeric', 'int', 'smallint', 'bigint', 'tinyint')
Then convert(varchar(MAX), NUMERIC_PRECISION)
When DATA_TYPE = 'bit'
Then convert(varchar(MAX), 1)
When DATA_TYPE IN ('decimal', 'float')
Then convert(varchar(MAX), Concat(Concat(NUMERIC_PRECISION, ', '), NUMERIC_SCALE))
When DATA_TYPE IN ('date', 'datetime', 'smalldatetime', 'time', 'timestamp')
Then ''
End As DATALEN,
DATA_TYPE

TABLE_NAME = ''
Firstly, you shouldn't have multiple elements with the same ID on a page - ID should be unique.
You could just remove the id attribute and and replace it with:
<input type='text' name='task'>
and to get an array of the values of task do
var taskArray = new Array();
$("input[name=task]").each(function() {
taskArray.push($(this).val());
});
Okay, here are the explanations.
e.keyCode - used to get the number that represents the key on the keyboard
e.charCode - a number that represents the unicode character of the key on keyboard
e.which - (jQuery specific) is a property introduced in jQuery (DO Not use in plain javascript)
Below is the code snippet to get the keyCode and charCode
<script>
// get key code
function getKey(event) {
event = event || window.event;
var keyCode = event.which || event.keyCode;
alert(keyCode);
}
// get char code
function getChar(event) {
event = event || window.event;
var keyCode = event.which || event.keyCode;
var typedChar = String.fromCharCode(keyCode);
alert(typedChar);
}
</script>

Here is how to assign a keyboard shortcut to a custom macro in Word 2013. The scenario is you created a macro named "fred" and you want to execute the macro by typing Ctrl+f.
By default the assignment is saved in the Normal.dotm document template. If this keyboard assignment is unique to this document then you may wish to change the "Save changes in" dropdown to your document name.
Disclaimer: other than the fact that references cannot be NULL nor "rebound" (meaning thay can't change the object they're the alias of), it really comes down to a matter of taste, so I'm not going to say "this is better".
That said, I disagree with your last statement in the post, in that I don't think the code loses clarity with references. In your example,
add_one(&a);
might be clearer than
add_one(a);
since you know that most likely the value of a is going to change. On the other hand though, the signature of the function
void add_one(int* const n);
is somewhat not clear either: is n going to be a single integer or an array? Sometimes you only have access to (poorly documentated) headers, and signatures like
foo(int* const a, int b);
are not easy to interpret at first sight.
Imho, references are as good as pointers when no (re)allocation nor rebinding (in the sense explained before) is needed. Moreover, if a developer only uses pointers for arrays, functions signatures are somewhat less ambiguous. Not to mention the fact that operators syntax is way more readable with references.
Doesn't log4j just use the application root directory if you don't specify a root directory in your FileAppender's path property? So you should just be able to use:
log4j.appender.file.File=logs/MyLog.log
It's been awhile since I've done Java web development, but this seems to be the most intuitive, and also doesn't collide with other unfortunately named logs writing to the ${catalina.home}/logs directory.

You can find the first and last visible children of the recycle view and check if the view you're looking for is in the range:
var visibleChild: View = rv.getChildAt(0)
val firstChild: Int = rv.getChildAdapterPosition(visibleChild)
visibleChild = rv.getChildAt(rv.childCount - 1)
val lastChild: Int = rv.getChildAdapterPosition(visibleChild)
println("first visible child is: $firstChild")

import vs. include
The primary purpose of an import is to import a namespace. A more common use of the XSD import statement is to import a namespace which appears in another file. You might be gathering the namespace information from the file, but don't forget that it's the namespace that you're importing, not the file (don't confuse an import
statement with an include
statement).
Another area of confusion is how to specify the location or path of the included .xsd
file: An XSD import statement has an optional attribute named schemaLocation
but it is not necessary if the namespace of the import statement is at the same location (in the same file) as the import statement itself.
When you do chose to use an external .xsd
file for your WSDL, the schemaLocation
attribute becomes necessary. Be very sure that the namespace you use in the import statement is the same as the targetNamespace of the schema you are importing. That is, all 3 occurrences must be identical:
WSDL:
xs:import namespace="urn:listing3" schemaLocation="listing3.xsd"/>
XSD:
<xsd:schema targetNamespace="urn:listing3"
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
Another approach to letting know the WSDL about the XSD is through Maven's pom.xml:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>xmlbeans-maven-plugin</artifactId>
<executions>
<execution>
<id>generate-sources-xmlbeans</id>
<phase>generate-sources</phase>
<goals>
<goal>xmlbeans</goal>
</goals>
</execution>
</executions>
<version>2.3.3</version>
<inherited>true</inherited>
<configuration>
<schemaDirectory>${basedir}/src/main/xsd</schemaDirectory>
</configuration>
</plugin>
You can read more on this in this great IBM article. It has typos such as xsd:import
instead of xs:import
but otherwise it's fine.
char*
is a mutable pointer to a mutable character/string.
const char*
is a mutable pointer to an immutable character/string. You cannot change the contents of the location(s) this pointer points to. Also, compilers are required to give error messages when you try to do so. For the same reason, conversion from const char *
to char*
is deprecated.
char* const
is an immutable pointer (it cannot point to any other location) but the contents of location at which it points are mutable.
const char* const
is an immutable pointer to an immutable character/string.
First, you need to convert your string to NSDate with its format. Then, you change the dateFormatter
to your simple format and convert it back to a String.
Swift 3
let dateString = "Thu, 22 Oct 2015 07:45:17 +0000"
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "EEE, dd MMM yyyy hh:mm:ss +zzzz"
dateFormatter.locale = Locale.init(identifier: "en_GB")
let dateObj = dateFormatter.date(from: dateString)
dateFormatter.dateFormat = "MM-dd-yyyy"
print("Dateobj: \(dateFormatter.string(from: dateObj!))")
The printed result is: Dateobj: 10-22-2015
Here is the command-line approach to answer this question:
gcloud compute firewall-rules create <rule-name> --allow tcp:9090 --source-tags=<list-of-your-instances-names> --source-ranges=0.0.0.0/0 --description="<your-description-here>"
This will open the port 9090
for the instances that you name. Omitting --source-tags
and --source-ranges
will apply the rule to all instances. More details are in the Gcloud documentation and the firewall-rule create
command manual
The previous answers are great, but Google recommends using the newer gcloud
commands instead of the gcutil
commands.
PS:
To get an idea of Google's firewall rules, run gcloud compute firewall-rules list
and view all your firewall rules
In case of SVN servers you have to creating a central repository with all projects. The contents of the repository can be uploaded with the Team/Share command; in case of the Subversive client it automatically runs a commit after the import, so you can upload your files.
This step cannot be circumvented in any way using a centralized version management system such as SVN.
Concerning more advanced usage, I find these two pages a must read:
mkdir()
creates only one directory at a time, if it is parent that one only. other wise it can create the sub directory(if the specified path is existed only) and do not create any directories in between any two directories. so it can not create smultiple directories in one directory
mkdirs()
create the multiple directories(in between two directories also) at a time.
Try to use the func below to add colorbar:
def add_colorbar(mappable):
from mpl_toolkits.axes_grid1 import make_axes_locatable
import matplotlib.pyplot as plt
last_axes = plt.gca()
ax = mappable.axes
fig = ax.figure
divider = make_axes_locatable(ax)
cax = divider.append_axes("right", size="5%", pad=0.05)
cbar = fig.colorbar(mappable, cax=cax)
plt.sca(last_axes)
return cbar
Then you codes need to be modified as:
fig , ( (ax1,ax2) , (ax3,ax4)) = plt.subplots(2, 2,sharex = True,sharey=True)
z1_plot = ax1.scatter(x,y,c = z1,vmin=0.0,vmax=0.4)
add_colorbar(z1_plot)
You can use list comprehension:
res_list = [i[0] for i in rows]
This should make the trick

You may use the ==
operator to compare unicode objects for equality.
>>> s1 = u'Hello'
>>> s2 = unicode("Hello")
>>> type(s1), type(s2)
(<type 'unicode'>, <type 'unicode'>)
>>> s1==s2
True
>>>
>>> s3='Hello'.decode('utf-8')
>>> type(s3)
<type 'unicode'>
>>> s1==s3
True
>>>
But, your error message indicates that you aren't comparing unicode objects. You are probably comparing a unicode
object to a str
object, like so:
>>> u'Hello' == 'Hello'
True
>>> u'Hello' == '\x81\x01'
__main__:1: UnicodeWarning: Unicode equal comparison failed to convert both arguments to Unicode - interpreting them as being unequal
False
See how I have attempted to compare a unicode object against a string which does not represent a valid UTF8 encoding.
Your program, I suppose, is comparing unicode objects with str objects, and the contents of a str object is not a valid UTF8 encoding. This seems likely the result of you (the programmer) not knowing which variable holds unicide, which variable holds UTF8 and which variable holds the bytes read in from a file.
I recommend http://nedbatchelder.com/text/unipain.html, especially the advice to create a "Unicode Sandwich."
I used exe4j to package all java jars into one final .exe file, which user can use it as normal windows application.
Another way to initialize an empty string is by using the built-in str()
function with no arguments.
str(object='')
Return a string containing a nicely printable representation of an object.
...
If no argument is given, returns the empty string, ''.
In the original example, that would look like this:
def __init__(self, mystr=str())
self.mystr = mystr
Personally, I believe that this better conveys your intentions.
Notice by the way that str()
itself sets a default parameter value of ''
.
If you want to reassign an element in an array, you can do the following:
var blah = ['Jan', 'Fed', 'Apr'];
console.log(blah);
function reassign(array, index, newValue) {
array[index] = newValue;
return array;
}
reassign(blah, [2], 'Mar');
Answering this just in case if someone else like me stumbles upon this post among many that advise use of JavaScripts for changing iframe height to 100%.
I strongly recommend that you see and try this option specified at How do you give iframe 100% height before resorting to a JavaScript based option. The referenced solution works perfectly for me in all of the testing I have done so far. Hope this helps someone.
To set the color of a font, you must first initialize the color by doing this:
Color maroon = new Color (128, 0, 0);
Once you've done that, you then put:
Font font = new Font ("Courier New", 1, 25); //Initializes the font
c.setColor (maroon); //Sets the color of the font
c.setFont (font); //Sets the font
c.drawString ("Your text here", locationX, locationY); //Outputs the string
Note: The 1 represents the type of font and this can be used to replace Font.PLAIN and the 25 represents the size of your font.

To stop the Xcode 8 iOS Simulator from logging like crazy, set an environment variable OS_ACTIVITY_MODE = disable in your debug scheme.
It worked.
Although adequate answers have already been given, I'd like to propose a less verbose solution, that can be used without the helper methods available in an MVC controller class. Using a third party library called "RazorEngine" you can use .Net file IO to get the contents of the razor file and call
string html = Razor.Parse(razorViewContentString, modelObject);
Get the third party library here.
I merely created a div class using various heights i.e.
<div class="divider-10"></div>
The CSS is:
.divider-10 {
width:100%;
min-height:1px;
margin-top:10px;
margin-bottom:10px;
display:inline-block;
position:relative;
}
Just create a divider class for what ever heights are needed.
Do you mean unique
:
R> x = c(1,1,2,3,4,4,4)
R> x
[1] 1 1 2 3 4 4 4
R> unique(x)
[1] 1 2 3 4
Expanding on the answer provided by @Nguyen - this function can be added to your .bashrc
etc and then called from the commandline to help clean up any image has dependent child images
errors...
You can run the function as yourself, and if a docker ps
fails, then it will run the docker
command with sudo
and prompt you for your password.
Does NOT delete images for any running containers!
docker_rmi_dependants ()
{
DOCKER=docker
[ docker ps >/dev/null 2>&1 ] || DOCKER="sudo docker"
echo "Docker: ${DOCKER}"
for n in $(${DOCKER} images | awk '$2 == "<none>" {print $3}');
do
echo "ImageID: $n";
${DOCKER} inspect --format='{{.Id}} {{.Parent}}' $(${DOCKER} images --filter since=$n -q);
done;
${DOCKER} rmi $(${DOCKER} images | awk '$2 == "<none>" {print $3}')
}
I also have this in my .bashrc
file...
docker_rm_dangling ()
{
DOCKER=docker
[ docker ps >/dev/null 2>&1 ] || DOCKER="sudo docker"
echo "Docker: ${DOCKER}"
${DOCKER} images -f dangling=true 2>&1 > /dev/null && YES=$?;
if [ $YES -eq 1 ]; then
read -t 30 -p "Press ENTER to remove, or CTRL-C to quit.";
${DOCKER} rmi $(${DOCKER} images -f dangling=true -q);
else
echo "Nothing to do... all groovy!";
fi
}
Works with:
$ docker --version
Docker version 17.05.0-ce, build 89658be
You can't add items to an array, since it has fixed length. What you're looking for is a List<string>
, which can later be turned to an array using list.ToArray()
, e.g.
List<string> list = new List<string>();
list.Add("Hi");
String[] str = list.ToArray();

Unlike other languages you may be used to, everything in C++ has to be declared before it can be used. The compiler will read your source file from top to bottom, so when it gets to the call to swapCase
, it doesn't know what it is so you get an error. You can declare your function ahead of main with a line like this:
void swapCase(char *name);
or you can simply move the entirety of that function ahead of main in the file. Don't worry about having the seemingly most important function (main) at the bottom of the file. It is very common in C or C++ to do that.

I know some people use Django specifically as an interface to abstract this type of database interaction. Django provides utilities that can be used for this:
from django.utils import timezone
now_aware = timezone.now()
You do need to set up a basic Django settings infrastructure, even if you are just using this type of interface (in settings, you need to include USE_TZ=True
to get an aware datetime).
By itself, this is probably nowhere near enough to motivate you to use Django as an interface, but there are many other perks. On the other hand, if you stumbled here because you were mangling your Django app (as I did), then perhaps this helps...

Basically, you need to check if a session was started before creating another one; ... more reading.
On the other hand, you chose to destroy an existing session before creating another one using session_destroy()
.
The best solution that worked great for me.
You have to: Copy this code to your main CSS file,
.responsive-video {
position: relative;
padding-bottom: 56.25%;
padding-top: 60px; overflow: hidden;
}
.responsive-video iframe,
.responsive-video object,
.responsive-video embed {
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
}
and then put your embeded video to
<div class="responsive-video">
<iframe ></iframe>
</div>
That’s it! Now you can use responsive videos on your site.
You'll do it the same way you would apply a css selector. For instanse you can do
$("#mydiv > .myclass")
or
$("#mydiv .myclass")
The last one will match every myclass inside myDiv, including myclass inside myclass.
Width auto
The initial width of a block level element like div or p is auto. This makes it expand to occupy all available horizontal space within its containing block. If it has any horizontal padding or border, the widths of those do not add to the total width of the element.
Width 100%
On the other hand, if you specify width:100%, the element’s total width will be 100% of its containing block plus any horizontal margin, padding and border (unless you’ve used box-sizing:border-box, in which case only margins are added to the 100% to change how its total width is calculated). This may be what you want, but most likely it isn’t.
To visualise the difference see this picture:
Using the START
command to run each program should get you what you need:
START "title" [/D path] [options] "command" [parameters]
Every START
invocation runs the command given in its parameter and returns immediately, unless executed with a /WAIT
switch.
That applies to command-line apps. Apps without command line return immediately anyway, so to be sure, if you want to run all asynchronously, use START
.
In newer version of git (2.23+) you can use:
git switch -C master origin/master
-C
is same as --force-create

I would recommend that you use the jQuery plugin for Verimail.js.
Why?
How?
Include verimail.jquery.js on your site and use the function:
$("input#email-address").verimail({
messageElement: "p#status-message"
});
If you have a form and want to validate the email on submit, you can use the getVerimailStatus-function:
if($("input#email-address").getVerimailStatus() < 0){
// Invalid email
}else{
// Valid email
}
Yes, it is possible. You might also want to define __all__
in __init__.py
files. It's a list of modules that will be imported when you do
from lib import *
Try adding autostart="false"
to your source tag.
<video width="640" height="480" controls="controls" type="video/mp4" preload="none">
<source src="http://example.com/mytestfile.mp4" autostart="false">
Your browser does not support the video tag.
</video>
I think your code is right. If you run the following code it converts the string '60' which is treated as varchar and it returns integer 60, if there is integer containing string in second it works.
select CONVERT(bigint,'60') as seconds
and it returns
60
Really fast, really easy:
srand(time(NULL)); // Seed the time
int finalNum = rand()%(max-min+1)+min; // Generate the number, assign to variable.
And that is it. However, this is biased towards the lower end, but if you are using C++ TR1/C++11 you can do it using the random
header to avoid that bias like so:
#include <random>
std::mt19937 rng(seed);
std::uniform_int_distribution<int> gen(min, max); // uniform, unbiased
int r = gen(rng);
But you can also remove the bias in normal C++ like this:
int rangeRandomAlg2 (int min, int max){
int n = max - min + 1;
int remainder = RAND_MAX % n;
int x;
do{
x = rand();
}while (x >= RAND_MAX - remainder);
return min + x % n;
}
and that was gotten from this post.
This also works:
...
WHERE
(FirstName IS NULL OR FirstName = ISNULL(@FirstName, FirstName)) AND
(LastName IS NULL OR LastName = ISNULL(@LastName, LastName)) AND
(Title IS NULL OR Title = ISNULL(@Title, Title))
Please find in the below code what I developed to support internationalization. It formats the given numeric value to language specific format. In the given example I have used ‘en’ while have tested for ‘es’, ‘fr’ and other countries where in the format varies. It not only stops user from keying characters but formats the value on tab out. Have created components for Number as well as for Decimal format. Apart from this have created parseNumber(value, locale) and parseDecimal(value, locale) functions which will parse the formatted data for any other business purposes. The said function will accept the formatted data and will return the non-formatted value. I have used JQuery validator plugin in the below shared code.

Use this query to create the new table with the values from existing table
CREATE TABLE New_Table_name AS SELECT * FROM Existing_table_Name;
Now you can get all the values from existing table into newly created table.
There are also some properties you can set to force a control to fill its available space when it would otherwise not do so. For example, you can say:
HorizontalContentAlignment="Stretch"
... to force the contents of a control to stretch horizontally. Or you can say:
HorizontalAlignment="Stretch"
... to force the control itself to stretch horizontally to fill its parent.

This was the good option for SEO because SEO gives the H1 tag high priority, inside the h1 tag should be your site name. Using this method if you search the site name in SEO it will show your site logo as well.
you want to hide the site name OR text please use text-indent in negative value. ex
h1 a {
text-indent: -99999px;
}
There's Pgloader that uses the aforementioned COPY
command and which can load data from csv (and MySQL, SQLite and dBase). It's also using separate threads for reading and copying data, so it's quite fast (interestingly enough, it got written from Python to Common Lisp and got a 20 to 30x speed gain, see blog post).
To load the csv file one needs to write a little configuration file, like
LOAD CSV
FROM 'path/to/file.csv' (x, y, a, b, c, d)
INTO postgresql:///pgloader?csv (a, b, d, c)
…
Simply you can write the following code snippet to convert an OpenCV image into a grey scale image
import cv2
image = cv2.imread('image.jpg',0)
cv2.imshow('grey scale image',image)
Observe that the image.jpg and the code must be saved in same folder.
Note that:
('image.jpg')
gives a RGB image('image.jpg',0)
gives Grey Scale Image.re.search
searches for the pattern throughout the string, whereas re.match
does not search the pattern; if it does not, it has no other choice than to match it at start of the string.

You defined one oracleCommand but used it in 'for'.
it means you are adding parameter with the same name to one OracleCommand.
you should use cmd.Parameters.clear()
to refresh your parameters.
for(int i=0;i<usersList.Count;i++)
{
if (!(selectedUsersArray[i].Equals("")) && !passwordArray[i].Equals(""))
{
cmd.Parameters.clear();//Add this line
OracleParameter userName = new OracleParameter();
userName.ParameterName = "user";
userName.Value = selectedUsersArray[i];
OracleParameter passwd = new OracleParameter();
passwd.ParameterName = "password";
passwd.Value = passwordArray[i];
cmd.Parameters.Add(userName);
cmd.Parameters.Add(passwd);
cmd.Prepare();
cmd.ExecuteNonQuery();
}

<form id="form1" runat="server">
<asp:LinkButton ID="LinkButton1" runat="server" /> <%-- included to force __doPostBack javascript function to be rendered --%>
<input type="button" id="Button45" name="Button45" onclick="javascript:__doPostBack('ButtonA','')" value="clicking this will run ButtonA.Click Event Handler" /><br /><br />
<input type="button" id="Button46" name="Button46" onclick="javascript:__doPostBack('ButtonB','')" value="clicking this will run ButtonB.Click Event Handler" /><br /><br />
<asp:Button runat="server" ID="ButtonA" ClientIDMode="Static" Text="ButtonA" /><br /><br />
<asp:Button runat="server" ID="ButtonB" ClientIDMode="Static" Text="ButtonB" />
</form>
Private Sub ButtonA_Click(sender As Object, e As System.EventArgs) Handles ButtonA.Click
Response.Write("You ran the ButtonA click event")
End Sub
Private Sub ButtonB_Click(sender As Object, e As System.EventArgs) Handles ButtonB.Click
Response.Write("You ran the ButtonB click event")
End Sub
Two input controls are rendered to the client:
<input type="hidden" name="__EVENTTARGET" id="__EVENTTARGET" value="" />
<input type="hidden" name="__EVENTARGUMENT" id="__EVENTARGUMENT" value="" />
__EVENTTARGET
receives argument 1 of __doPostBack__EVENTARGUMENT
receives argument 2 of __doPostBackThe __doPostBack function is rendered out like this:
function __doPostBack(eventTarget, eventArgument) {
if (!theForm.onsubmit || (theForm.onsubmit() != false)) {
theForm.__EVENTTARGET.value = eventTarget;
theForm.__EVENTARGUMENT.value = eventArgument;
theForm.submit();
}
}
When the form submits / postback occurs:
javascript:__doPostBack('ButtonB','')
, then the button click handler for that button will be run.You can pass whatever you want as arguments to __doPostBack
You can then analyze the hidden input values and run specific code accordingly:
If Request.Form("__EVENTTARGET") = "DoSomethingElse" Then
Response.Write("Do Something else")
End If
ClientIDMode="Static"
, then you can do something like this: __doPostBack('<%= myclientid.UniqueID %>', '')
. __doPostBack('<%= MYBUTTON.UniqueID %>','')
<?php
$j=1;
array_reverse($skills_nav);
foreach ( $skills_nav as $skill ) {

$a .= '</a></li>';
echo $a;
echo "\n";
$j++;
}

It's good to know the differences between margin
and padding
. Here are some differences:
Margin is outer space of an element, while padding is inner space of an element.
Margin is the space outside the border of an element, while padding is the space inside the border of it.
Margin accepts the value of auto: margin: auto
, but you can't set padding to auto.
Margin can be set to any number, but padding must be non-negative.
When you style an element, padding will also be affected (e.g. background color), but not margin.
Yes, you need to use PropTypes.arrayOf
instead of PropTypes.array
in the code, you can do something like this:
import PropTypes from 'prop-types';
MyComponent.propTypes = {
annotationRanges: PropTypes.arrayOf(
PropTypes.shape({
start: PropTypes.string.isRequired,
end: PropTypes.number.isRequired
}).isRequired
).isRequired
}
Also for more details about proptypes, visit Typechecking With PropTypes here
You use something like
from flask import send_file
@app.route('/get_image')
def get_image():
if request.args.get('type') == '1':
filename = 'ok.gif'
else:
filename = 'error.gif'
return send_file(filename, mimetype='image/gif')
to send back ok.gif
or error.gif
, depending on the type query parameter. See the documentation for the send_file
function and the request
object for more information.
You can do something like this
import React from 'react';
class Header extends React.Component {
constructor() {
super();
}
checkClick(e, notyId) {
alert(notyId);
}
render() {
return (
<PopupOver func ={this.checkClick } />
)
}
};
class PopupOver extends React.Component {
constructor(props) {
super(props);
this.props.func(this, 1234);
}
render() {
return (
<div className="displayinline col-md-12 ">
Hello
</div>
);
}
}
export default Header;
Using statics
var MyComponent = React.createClass({
statics: {
customMethod: function(foo) {
return foo === 'bar';
}
},
render: function() {
}
});
MyComponent.customMethod('bar'); // true
It sounds like the populate method is what your looking for. First make small change to your post schema:
var postSchema = new Schema({
name: String,
postedBy: {type: mongoose.Schema.Types.ObjectId, ref: 'User'},
dateCreated: Date,
comments: [{body:"string", by: mongoose.Schema.Types.ObjectId}],
});
Then make your model:
var Post = mongoose.model('Post', postSchema);
Then, when you make your query, you can populate references like this:
Post.findOne({_id: 123})
.populate('postedBy')
.exec(function(err, post) {
// do stuff with post
});
I came here with the same Error, though one with a different origin.
It is caused by unsupported float index in 1.12.0 and newer numpy versions even if the code should be considered as valid.
An int
type is expected, not a np.float64
Solution: Try to install numpy 1.11.0
sudo pip install -U numpy==1.11.0.
Here's the pseudo-code which should be convertible into any procedural language:
array = [2, 42, 82, 122, 162, 202, 242, 282, 322, 362]
number = 112
print closest (number, array)
def closest (num, arr):
curr = arr[0]
foreach val in arr:
if abs (num - val) < abs (num - curr):
curr = val
return curr
It simply works out the absolute differences between the given number and each array element and gives you back one of the ones with the minimal difference.
For the example values:
number = 112 112 112 112 112 112 112 112 112 112
array = 2 42 82 122 162 202 242 282 322 362
diff = 110 70 30 10 50 90 130 170 210 250
|
+-- one with minimal absolute difference.
As a proof of concept, here's the Python code I used to show this in action:
def closest (num, arr):
curr = arr[0]
for index in range (len (arr)):
if abs (num - arr[index]) < abs (num - curr):
curr = arr[index]
return curr
array = [2, 42, 82, 122, 162, 202, 242, 282, 322, 362]
number = 112
print closest (number, array)
And, if you really need it in Javascript, see below for a complete HTML file which demonstrates the function in action:
<html>
<head></head>
<body>
<script language="javascript">
function closest (num, arr) {
var curr = arr[0];
var diff = Math.abs (num - curr);
for (var val = 0; val < arr.length; val++) {
var newdiff = Math.abs (num - arr[val]);
if (newdiff < diff) {
diff = newdiff;
curr = arr[val];
}
}
return curr;
}
array = [2, 42, 82, 122, 162, 202, 242, 282, 322, 362];
number = 112;
alert (closest (number, array));
</script>
</body>
</html>
Now keep in mind there may be scope for improved efficiency if, for example, your data items are sorted (that could be inferred from the sample data but you don't explicitly state it). You could, for example, use a binary search to find the closest item.
You should also keep in mind that, unless you need to do it many times per second, the efficiency improvements will be mostly unnoticable unless your data sets get much larger.
If you do want to try it that way (and can guarantee the array is sorted in ascending order), this is a good starting point:
<html>
<head></head>
<body>
<script language="javascript">
function closest (num, arr) {
var mid;
var lo = 0;
var hi = arr.length - 1;
while (hi - lo > 1) {
mid = Math.floor ((lo + hi) / 2);
if (arr[mid] < num) {
lo = mid;
} else {
hi = mid;
}
}
if (num - arr[lo] <= arr[hi] - num) {
return arr[lo];
}
return arr[hi];
}
array = [2, 42, 82, 122, 162, 202, 242, 282, 322, 362];
number = 112;
alert (closest (number, array));
</script>
</body>
</html>
It basically uses bracketing and checking of the middle value to reduce the solution space by half for each iteration, a classic O(log N)
algorithm whereas the sequential search above was O(N)
:
0 1 2 3 4 5 6 7 8 9 <- indexes
2 42 82 122 162 202 242 282 322 362 <- values
L M H L=0, H=9, M=4, 162 higher, H<-M
L M H L=0, H=4, M=2, 82 lower/equal, L<-M
L M H L=2, H=4, M=3, 122 higher, H<-M
L H L=2, H=3, difference of 1 so exit
^
|
H (122-112=10) is closer than L (112-82=30) so choose H
As stated, that shouldn't make much of a difference for small datasets or for things that don't need to be blindingly fast, but it's an option you may want to consider.
git reset c14809fafb08b9e96ff2879999ba8c807d10fb07
is what you're after...
The accepted answer is not correct. Best is to use a library for escaping xml.
As mentioned in this other question
"Basically, the control characters and characters out of the Unicode ranges are not allowed. This means also that calling for example the character entity is forbidden."
If you only escape the five characters. You can have problems like An invalid XML character (Unicode: 0xc) was found
If you are using the following Windows versions or later: Windows Server 2012, Windows Server 2012 R2, or Windows 8.1 then MakeCert is now deprecated, and Microsoft recommends using the PowerShell Cmdlet New-SelfSignedCertificate.
If you're using an older version such as Windows 7, you'll need to stick with MakeCert or another solution. Some people suggest the Public Key Infrastructure Powershell (PSPKI) Module.
While you can create a self-signed code-signing certificate (SPC - Software Publisher Certificate) in one go, I prefer to do the following:
makecert -r -pe -n "CN=My CA" -ss CA -sr CurrentUser ^
-a sha256 -cy authority -sky signature -sv MyCA.pvk MyCA.cer
(^ = allow batch command-line to wrap line)
This creates a self-signed (-r) certificate, with an exportable private key (-pe). It's named "My CA", and should be put in the CA store for the current user. We're using the SHA-256 algorithm. The key is meant for signing (-sky).
The private key should be stored in the MyCA.pvk file, and the certificate in the MyCA.cer file.
Because there's no point in having a CA certificate if you don't trust it, you'll need to import it into the Windows certificate store. You can use the Certificates MMC snapin, but from the command line:
certutil -user -addstore Root MyCA.cer
makecert -pe -n "CN=My SPC" -a sha256 -cy end ^
-sky signature ^
-ic MyCA.cer -iv MyCA.pvk ^
-sv MySPC.pvk MySPC.cer
It is pretty much the same as above, but we're providing an issuer key and certificate (the -ic and -iv switches).
We'll also want to convert the certificate and key into a PFX file:
pvk2pfx -pvk MySPC.pvk -spc MySPC.cer -pfx MySPC.pfx
If you want to protect the PFX file, add the -po switch, otherwise PVK2PFX creates a PFX file with no passphrase.
signtool sign /v /f MySPC.pfx ^
/t http://timestamp.url MyExecutable.exe
(See why timestamps may matter)
If you import the PFX file into the certificate store (you can use PVKIMPRT or the MMC snapin), you can sign code as follows:
signtool sign /v /n "Me" /s SPC ^
/t http://timestamp.url MyExecutable.exe
Some possible timestamp URLs for signtool /t
are:
http://timestamp.verisign.com/scripts/timstamp.dll
http://timestamp.globalsign.com/scripts/timstamp.dll
http://timestamp.comodoca.com/authenticode
For those who are not .NET developers, you will need a copy of the Windows SDK and .NET framework. A current link is available here: SDK & .NET (which installs makecert in C:\Program Files\Microsoft SDKs\Windows\v7.1
). Your mileage may vary.
MakeCert is available from the Visual Studio Command Prompt. Visual Studio 2015 does have it, and it can be launched from the Start Menu in Windows 7 under "Developer Command Prompt for VS 2015" or "VS2015 x64 Native Tools Command Prompt" (probably all of them in the same folder).
I had also faced same error when i was trying to call bootstrap modal from jquery. But this happens because we are using bootstrap modal and for this we need to attach one cdn bootstrap.min.js which is
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
Hope this will help as I missed that when i was trying to call bootstrap modal from jQuery using
$('#button').on('click',function(){
$('#myModal').modal();
});
myModal
is the id of Bootstrap modal
and you have to give a click event to a button when you call click that button a pop up modal will be displayed.
-> mysql -h host -u user -p database_name table_name < test_table.sql
It works for me... and should be faster in most case (if not all) than querying a DNS server. Thanks to Dr. Wily's Apprentice (here).

Try this:
Add UIWebView to View.
Connect UIWebview outlet using assistant editor and name your "webview".
UIWebView Load URL.
@IBOutlet weak var webView: UIWebView!
override func viewDidLoad() {
super.viewDidLoad()
// Your webView code goes here
let url = URL(string: "https://www.example.com")
let requestObj = URLRequest(url: url! as URL)
webView.load(requestObj)
}
And run the app!!
You can do that using CSS's background
propieties. There are few ways to do it:
HTML:
<div id="div-with-bg"></div>
CSS:
#div-with-bg
{
background: color url('path') others;
}
HTML:
<div class="div-with-bg"></div>
CSS:
.div-with-bg
{
background: color url('path') others;
}
HTML:
<div style="background: color url('path')"></div>
Where:
background
CSS Property is a connection of all background-xxx propieties in that syntax:
background: background-color background-image background-repeat background-attachment background-position;

Wrap your formula with IFERROR
.
=IFERROR(yourformula)
You can redirect by this method also:
return Yii::$app->response->redirect(['user/index', 'id' => 10]);
If you want to send the Header information immediately use with send().This method adds a Location header to the current response.
return Yii::$app->response->redirect(['user/index', 'id' => 10])->send();
If you want the complete URL then use like Url::to(['user/index', 'id' => 302])
with the header of use yii\helpers\Url;
.
For more information check Here. Hope this will help someone.
I do not believe this is possible. You could add class1
to all elements which also have class2
. If this is not practical to do manually, you could do it automatically with JavaScript (fairly easy to do with jQuery).
The first answer works very well, but for ZERO / 0 it will format as .00
Hence the format #,##0.00 is working well for me. Always test different numbers such as 0 / 100 / 2334.30 and negative numbers before deploying to production system.
Here is the regex for the Internet Email Address using the RegularExpressionValidator in .NET
\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*
By the way if you put a RegularExpressionValidator on the page and go to the design view there is a ValidationExpression field that you can use to choose from a list of expressions provided by .NET. Once you choose the expression you want there is a Validation expression: textbox that holds the regex used for the validator
var uniq = allvalues.GroupBy(x => x.Id).Select(y=>y.First()).Distinct();

You can get a request parameter id using the expression:

$radio_input = $_POST['radio'];
echo $radio_input;
}
} else {
}

Sometime floats brake the vertical align, is better to avoid them.
This could also be an issue of port 80 being used by "Web Deployment Agent Service". you can stop it from administrative tools->services and free up that port. as shown here
After hours of searching I think my problem was that command yum install php-soap
installs the latest version of soap for the latest php version.
My php version was 7.027
, but latest php version is 7.2
so I had to search for the right soap version and finaly found it HERE!
yum install rh-php70-php-soap
Now php -m | grep -i soap
works, Output: soap

There are some cases, when textbox will not handle enter key. I think it may be when you have accept button set on form. In that case, instead of KeyDown
event you should use textbox1_PreviewKeyDown(object sender, PreviewKeyDownEventArgs e)
Use ready event of document :
$(document).ready(function(){ /* the click code */ });
And it is better to use bind method for event handeling. because you don't want to call click action in every load of page
$(':submit').bind('click' , function () { /* ... */ });
I solved similar MySQL error & I think this answer will help you to fix the same type of MySQL database error.
Solution:
Take Backup of MySQL “data” Folder
First of all you should create a backup of the “data” folder using any compression software.
Give a name like “data_backup.zip” or any type of compression you wish.
I used winrar compression software to compress & backup mysql “data” folder.
Rename the “data” folder
Create a new “data” folder
Copy content from “backup” folder
Transfer all MySQL projects Database, Data file & Log files
If you have many database which was used for various projects, then you have to transfer all database from “data-oldfiles” folder to “data” folder.
Copy all databases from the data-old files and paste to the data folder.
Now you have to copy the data file “ibdata1” & all log files “ib_logfile0, ib_logfile1 ” from data-old files folder to the data folder.
If you have many id_logiles then copied all of them.
Now Start MySQL from XAMPP.
Go to phpMyAdmin to check all databases are available & working.
Now start your any website project from localhost to check the MySQL database.
The Problem is solved !!
You can read the details tutorials on the link bellow: Error: MySQL shutdown unexpectedly – Solution in 5 easy steps
You can also watch video tutorials to solve the problem:
Araxis Merge. It is commerical, but it is so worth it... It is available for Windows and the Mac OS X.
Using custom exception class you can return different HTTP status code and dto object.
@PostMapping("/save")
public ResponseEntity<UserDto> saveUser(@RequestBody UserDto userDto) {
if(userDto.getId() != null) {
throw new UserNotFoundException("A new user cannot already have an ID");
}
return ResponseEntity.ok(userService.saveUser(userDto));
}
Exception class
import org.springframework.http.HttpStatus;
import org.springframework.web.bind.annotation.ResponseStatus;
@ResponseStatus(value = HttpStatus.NOT_FOUND, reason = "user not found")
public class UserNotFoundException extends RuntimeException {
public UserNotFoundException(String message) {
super(message);
}
}
Another solution which, in my opinion, is easier to read would be:
UPDATE test
SET something = 1, field = IF(condition is true, 1, field)
WHERE id = 123
What this does is set 'field' to 1 (like OP used as example) if the condition is met and use the current value of 'field' if not met. Using the previous value is the same as not changing, so there you go.
To build on other answers above, in case you have a Spring boot REST service application (not Spring MVC) with Spring security, then enabling CORS via Spring security is enough (if you use Spring MVC then using a WebMvcConfigurer
bean as mentioned by Yogen could be the way to go as Spring security will delegate to the CORS definition mentioned therein)
So you need to have a security config that does the following:
@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
//other http security config
http.cors().configurationSource(corsConfigurationSource());
}
//This can be customized as required
CorsConfigurationSource corsConfigurationSource() {
CorsConfiguration configuration = new CorsConfiguration();
List<String> allowOrigins = Arrays.asList("*");
configuration.setAllowedOrigins(allowOrigins);
configuration.setAllowedMethods(singletonList("*"));
configuration.setAllowedHeaders(singletonList("*"));
//in case authentication is enabled this flag MUST be set, otherwise CORS requests will fail
configuration.setAllowCredentials(true);
UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
source.registerCorsConfiguration("/**", configuration);
return source;
}
}
This link has more information on the same: https://docs.spring.io/spring-security/site/docs/current/reference/htmlsingle/#cors
Note:
UserDetailsService
for example) then the configuration.setAllowCredentials(true);
must be addedTested for Spring boot 2.0.0.RELEASE (i.e., Spring 5.0.4.RELEASE and Spring security 5.0.3.RELEASE)
Use JSON_UNESCAPED_UNICODE
inside json_encode()
if your php version >=5.4.
You need to iterate over the array
for ($i = 0, $c = count($array); $i < $c; ++$i) {
$array[$i] = (array) $array[$i];
}
ans use (array)
conversion because you have array of objects of Std class and not object itself
Example:
$users = DB::table('users')->get();
var_dump($users);
echo "<br /><br />";
for ($i = 0, $c = count($users); $i < $c; ++$i) {
$users[$i] = (array) $users[$i];
}
var_dump($users);
exit;
Output for this is:
array(1) { [0]=> object(stdClass)#258 (8) { ["id"]=> int(1) ["user_name"]=> string(5) "admin" ["email"]=> string(11) "admin@admin" ["passwd"]=> string(60) "$2y$10$T/0fW18gPGgz0CILTy2hguxNpcNjYZHsTyf5dvpor9lYMw/mtKYfi" ["balance"]=> string(4) "0.00" ["remember_token"]=> string(60) "moouXQOJFhtxkdl9ClEXYh9ioBSsRp28WZZbLPkJskcCr0325TyrxDK4al5H" ["created_at"]=> string(19) "2014-10-01 12:00:00" ["updated_at"]=> string(19) "2014-09-27 12:20:54" } }
array(1) { [0]=> array(8) { ["id"]=> int(1) ["user_name"]=> string(5) "admin" ["email"]=> string(11) "admin@admin" ["passwd"]=> string(60) "$2y$10$T/0fW18gPGgz0CILTy2hguxNpcNjYZHsTyf5dvpor9lYMw/mtKYfi" ["balance"]=> string(4) "0.00" ["remember_token"]=> string(60) "moouXQOJFhtxkdl9ClEXYh9ioBSsRp28WZZbLPkJskcCr0325TyrxDK4al5H" ["created_at"]=> string(19) "2014-10-01 12:00:00" ["updated_at"]=> string(19) "2014-09-27 12:20:54" } }
as expected. Object of stdClass
has been converted to array.
You have to manually copy each key/value pair to a new map
. This is a loop that people have to reprogram any time they want a deep copy of a map
.
You can automatically generate the function for this by installing mapper
from the maps
package using
go get -u github.com/drgrib/maps/cmd/mapper
and running
mapper -types string:aStruct
which will generate the file map_float_astruct.go
containing not only a (deep) Copy
for your map but also other "missing" map
functions ContainsKey
, ContainsValue
, GetKeys
, and GetValues
:
func ContainsKeyStringAStruct(m map[string]aStruct, k string) bool {
_, ok := m[k]
return ok
}
func ContainsValueStringAStruct(m map[string]aStruct, v aStruct) bool {
for _, mValue := range m {
if mValue == v {
return true
}
}
return false
}
func GetKeysStringAStruct(m map[string]aStruct) []string {
keys := []string{}
for k, _ := range m {
keys = append(keys, k)
}
return keys
}
func GetValuesStringAStruct(m map[string]aStruct) []aStruct {
values := []aStruct{}
for _, v := range m {
values = append(values, v)
}
return values
}
func CopyStringAStruct(m map[string]aStruct) map[string]aStruct {
copyMap := map[string]aStruct{}
for k, v := range m {
copyMap[k] = v
}
return copyMap
}
Full disclosure: I am the creator of this tool. I created it and its containing package because I found myself constantly rewriting these algorithms for the Go map
for different type combinations.
The current answers are a bit out of date so, for clarity:
The short answer is:

There are a few ways CSS can 'target' navigation. This will style internal and external links using attribute styling, which could help signal visitors to what your links will do.
a[href="#"] { color: forestgreen; font-weight: normal; }
a[href="http"] { color: dodgerblue; font-weight: normal; }
You can also target the traditional inline HTML 'target=_blank'.
a[target=_blank] { font-weight: bold; }
Also :target selector to style navigation block and element targets.
nav { display: none; }
nav:target { display: block; }
CSS :target pseudo-class selector is supported - caniuse, w3schools, MDN.
a[href="http"] { target: new; target-name: new; target-new: tab; }
CSS/CSS3 'target-new' property etc, not supported by any major browsers, 2017 August, though it is part of the W3 spec since 2004 February.
W3Schools 'modal' construction, uses ':target' pseudo-class that could contain WP navigation. You can also add HTML rel="noreferrer and noopener beside target="_blank" to improve 'new tab' performance. CSS will not open links in tabs for now, but this page explains how to do that with jQuery (compatibility may depend for WP coders). MDN has a good review at Using the :target pseudo-class in selectors
From Django docs:
The include tag should be considered as an implementation of "render this subtemplate and include the HTML", not as "parse this subtemplate and include its contents as if it were part of the parent". This means that there is no shared state between included templates -- each include is a completely independent rendering process.
So Django doesn't grab any blocks from your commondata.html and it doesn't know what to do with rendered html outside blocks.
I had to add !important
to get it to work. I also made my own class button-primary-override
.
.button-primary-override:hover,
.button-primary-override:active,
.button-primary-override:focus,
.button-primary-override:visited{
background-color: #42A5F5 !important;
border-color: #42A5F5 !important;
background-image: none !important;
border: 0 !important;
}
Please post your Model Class.
To check the errors in your ModelState
use the following code:
var errors = ModelState
.Where(x => x.Value.Errors.Count > 0)
.Select(x => new { x.Key, x.Value.Errors })
.ToArray();
OR: You can also use
var errors = ModelState.Values.SelectMany(v => v.Errors);
Place a break point at the above line and see what are the errors in your ModelState
.
Merely for the purposes of making your program work, take the contents of your main() method and put them in a constructor:
public BookStoreApp2()
{
// Put contents of main method here
}
Then, in your main() method. Do this:
public void main( String[] args )
{
new BookStoreApp2();
}
Simple way is
ArrayList<Dog> dogs = getDogs();
ArrayList<Dog> clonedList = new ArrayList<Dog>(dogs);
At least with Miniconda (I assume it's the same for Anaconda), within the environment folder, the packages are installed in a folder called \conda-meta.
i.e.
C:\Users\username\Miniconda3\envs\environmentname\conda-meta
If you install on the base environment, the location is:
C:\Users\username\Miniconda3\pkgs
I had no success with other attempts on a SQL Server 2012. What I did was use SQL Server Management Studio to generate a script to change the value, and got this:
USE [master]
GO
EXEC xp_instance_regwrite N'HKEY_LOCAL_MACHINE', N'Software\Microsoft\MSSQLServer\MSSQLServer', N'LoginMode', REG_DWORD, 2
GO
After that, I enabled the sa
account using this:
ALTER LOGIN sa ENABLE ;
GO
ALTER LOGIN sa WITH PASSWORD = '<strongPasswordHere>' ;
GO
...then, I restarted the service, and everything worked!
This worked best for me
"0x%02X" % 5 # => 0x05
"0x%02X" % 17 # => 0x11
Change the (2) if you want a number with a bigger width (2 is for 2 hex printned chars) so 3 will give you the following
"0x%03X" % 5 # => 0x005
"0x%03X" % 17 # => 0x011
According to http://caniuse.com/#feat=flexbox:
"IE10 and IE11 default values for flex
are 0 0 auto
rather than 0 1 auto
, as per the draft spec, as of September 2013"
So in plain words, if somewhere in your CSS you have something like this: flex:1
, that is not translated the same way in all browsers. Try changing it to 1 0 0
and I believe you will immediately see that it -kinda- works.
The problem is that this solution will probably mess up firefox, but then you can use some hacks to target only Mozilla and change it back:
@-moz-document url-prefix() {
#flexible-content{
flex: 1;
}
}
Since flexbox
is a W3C Candidate and not official, browsers tend to give different results, but I guess that will change in the immediate future.
If someone has a better answer I would like to know!
$array = array(0 => 100, "color" => "red");
print_r(array_keys($array));
in your server side the code looks like:
var request = require('request');
app.post('/add', function(req, res){
console.log(req.body);
request.post(
{
url:'http://localhost:6001/add',
json: {
unit_name:req.body.unit_name,
unit_price:req.body.unit_price
},
headers: {
'Content-Type': 'application/json'
}
},
function(error, response, body){
// console.log(error);
// console.log(response);
console.log(body);
res.send(body);
});
// res.send("body");
});
in receiving end server code looks like:
app.post('/add', function(req, res){
console.log('received request')
console.log(req.body);
let adunit = new AdUnit(req.body);
adunit.save()
.then(game => {
res.status(200).json({'adUnit':'AdUnit is added successfully'})
})
.catch(err => {
res.status(400).send('unable to save to database');
})
});
Schema is just two properties unit_name and unit_price.

Use sp_helptext
before the view_name
. Example:
sp_helptext Example_1
Hence you will get the query:
CREATE VIEW dbo.Example_1
AS
SELECT a, b, c
FROM dbo.table_name JOIN blah blah blah
WHERE blah blah blah
sp_helptext will give stored procedures.

My setup was a little different using XAMPP. in httpd-xampp.conf I had to make the following change.
Alias /phpmyadmin "C:/xampp/phpMyAdmin/"
<Directory "C:/xampp/phpMyAdmin">
AllowOverride AuthConfig
Require local
ErrorDocument 403 /error/XAMPP_FORBIDDEN.html.var
</Directory>
change to
Alias /phpmyadmin "C:/xampp/phpMyAdmin/"
<Directory "C:/xampp/phpMyAdmin">
AllowOverride AuthConfig
#makes it so I can config the database from anywhere
#change the line below
Require all granted
ErrorDocument 403 /error/XAMPP_FORBIDDEN.html.var
</Directory>
I need to state that I'm brand new at this so I'm just hacking around but this is how I got it working.
As balusC said SERVER_NAME is not reliable and can be changed in apache config , server name config of server and firewall that can be between you and server.
Following function always return real host (user typed host) without port and it's almost reliable:
function getRealHost(){
list($realHost,)=explode(':',$_SERVER['HTTP_HOST']);
return $realHost;
}
You can use a HashingStrategy based Map
from Eclipse Collections
HashingStrategy<String> hashingStrategy =
HashingStrategies.fromFunction(String::toUpperCase);
MutableMap<String, String> node = HashingStrategyMaps.mutable.of(hashingStrategy);
Note: I am a contributor to Eclipse Collections.

If you want to make a thumbnail of a UIImage (with proportional resizing or maybe some cropping involved), check out UIImage+Resize category that allows you to use concise, ImageMagick-like syntax:
UIImage* squareImage = [image resizedImageByMagick: @"320x320#"];
Here is an example that takes a user's input and checks if the input is a palindrome:
name = input("Write your word here: ")
input("Press <enter> to check if the word is a palindrome.")
if str(name) == str(name)[::-1]:
print("True")
else:
print("False")
However, there is no need to even set up the if
/else
statement. You can directly print the result of the logical comparison, as shown here:
name = input("Write your word here: ")
input("Press <enter> to check if the word is a palindrome.")
print(str(name) == str(name)[::-1])
The function ob_start() will turn output buffering on. While output buffering is active no output is sent from the script (other than headers), instead the output is stored in an internal buffer. So browser will not receive any output and the header will work.Also we should make sure that header() is used on the top of the code.
I also faced the same problem and figured the problem was happening as the layout_width of the TextView was having wrap_content. You need to have layout_width as match_parent and the android:gravity = "gravity"
This is a simple thing in Android Studio,
go to: res folder -> values -> strings.xml
change the app_name (in the bellow example:MitsuhoSdn Bhd) to any new name you want.

On step 3, you might try also to add file:///c:/path/portecle.jnlp, but this addition didn't help with my case.
As olt already pointed out, Image.paste

Compositing image using Image.paste
like so:
final1 = Image.new("RGBA", layer1.size)
final1.paste(layer1, (0,0), layer1)
final1.paste(layer2, (0,0), layer2)
produces the following image (the alpha part of the overlayed red pixels is completely taken from the 2nd layer. The pixels are not blended correctly):
Compositing image using Image.alpha_composite
like so:
final2 = Image.new("RGBA", layer1.size)
final2 = Image.alpha_composite(final2, layer1)
final2 = Image.alpha_composite(final2, layer2)
produces the following (correct) image:

Or you could just simulate a click on the refresh button
// If recaptcha object exists, refresh it
if (typeof Recaptcha != "undefined") {
jQuery('#recaptcha_reload').click();
}
Overall I don't see anything that would break in your code.
Two suggestions:
The way you are combining Buffer
objects is a suboptimal because it has to copy all the pre-existing data on every 'data' event. It would be better to put the chunks in an array and concat
them all at the end.
var bufs = [];
stdout.on('data', function(d){ bufs.push(d); });
stdout.on('end', function(){
var buf = Buffer.concat(bufs);
}
For performance, I would look into if the S3 library you are using supports streams. Ideally you wouldn't need to create one large buffer at all, and instead just pass the stdout
stream directly to the S3 library.
As for the second part of your question, that isn't possible. When a function is called, it is allocated its own private context, and everything defined inside of that will only be accessible from other items defined inside that function.
Dumping the file to the filesystem would probably mean less memory usage per request, but file IO can be pretty slow so it might not be worth it. I'd say that you shouldn't optimize too much until you can profile and stress-test this function. If the garbage collector is doing its job you may be overoptimizing.
With all that said, there are better ways anyway, so don't use files. Since all you want is the length, you can calculate that without needing to append all of the buffers together, so then you don't need to allocate a new Buffer at all.
var pause_stream = require('pause-stream');
// Your other code.
var bufs = [];
stdout.on('data', function(d){ bufs.push(d); });
stdout.on('end', function(){
var contentLength = bufs.reduce(function(sum, buf){
return sum + buf.length;
}, 0);
// Create a stream that will emit your chunks when resumed.
var stream = pause_stream();
stream.pause();
while (bufs.length) stream.write(bufs.shift());
stream.end();
var headers = {
'Content-Length': contentLength,
// ...
};
s3.putStream(stream, ....);
You do it exactly as you showed with this line:
get.setHeader("Content-Type", "application/x-zip");
So your header is fine and the problem is some other input to the web service. You'll want to debug that on the server side.
This answer is all about authorization and it is a complement of my previous answer about authentication
Why another answer? I attempted to expand my previous answer by adding details on how to support JSR-250 annotations. However the original answer became the way too long and exceeded the maximum length of 30,000 characters. So I moved the whole authorization details to this answer, keeping the other answer focused on performing authentication and issuing tokens.
@Secured
annotationBesides authentication flow shown in the other answer, role-based authorization can be supported in the REST endpoints.
Create an enumeration and define the roles according to your needs:
public enum Role {
ROLE_1,
ROLE_2,
ROLE_3
}
Change the @Secured
name binding annotation created before to support roles:
@NameBinding
@Retention(RUNTIME)
@Target({TYPE, METHOD})
public @interface Secured {
Role[] value() default {};
}
And then annotate the resource classes and methods with @Secured
to perform the authorization. The method annotations will override the class annotations:
@Path("/example")
@Secured({Role.ROLE_1})
public class ExampleResource {
@GET
@Path("{id}")
@Produces(MediaType.APPLICATION_JSON)
public Response myMethod(@PathParam("id") Long id) {
// This method is not annotated with @Secured
// But it's declared within a class annotated with @Secured({Role.ROLE_1})
// So it only can be executed by the users who have the ROLE_1 role
...
}
@DELETE
@Path("{id}")
@Produces(MediaType.APPLICATION_JSON)
@Secured({Role.ROLE_1, Role.ROLE_2})
public Response myOtherMethod(@PathParam("id") Long id) {
// This method is annotated with @Secured({Role.ROLE_1, Role.ROLE_2})
// The method annotation overrides the class annotation
// So it only can be executed by the users who have the ROLE_1 or ROLE_2 roles
...
}
}
Create a filter with the AUTHORIZATION
priority, which is executed after the AUTHENTICATION
priority filter defined previously.
The ResourceInfo
can be used to get the resource Method
and resource Class
that will handle the request and then extract the @Secured
annotations from them:
@Secured
@Provider
@Priority(Priorities.AUTHORIZATION)
public class AuthorizationFilter implements ContainerRequestFilter {
@Context
private ResourceInfo resourceInfo;
@Override
public void filter(ContainerRequestContext requestContext) throws IOException {
// Get the resource class which matches with the requested URL
// Extract the roles declared by it
Class<?> resourceClass = resourceInfo.getResourceClass();
List<Role> classRoles = extractRoles(resourceClass);
// Get the resource method which matches with the requested URL
// Extract the roles declared by it
Method resourceMethod = resourceInfo.getResourceMethod();
List<Role> methodRoles = extractRoles(resourceMethod);
try {
// Check if the user is allowed to execute the method
// The method annotations override the class annotations
if (methodRoles.isEmpty()) {
checkPermissions(classRoles);
} else {
checkPermissions(methodRoles);
}
} catch (Exception e) {
requestContext.abortWith(
Response.status(Response.Status.FORBIDDEN).build());
}
}
// Extract the roles from the annotated element
private List<Role> extractRoles(AnnotatedElement annotatedElement) {
if (annotatedElement == null) {
return new ArrayList<Role>();
} else {
Secured secured = annotatedElement.getAnnotation(Secured.class);
if (secured == null) {
return new ArrayList<Role>();
} else {
Role[] allowedRoles = secured.value();
return Arrays.asList(allowedRoles);
}
}
}
private void checkPermissions(List<Role> allowedRoles) throws Exception {
// Check if the user contains one of the allowed roles
// Throw an Exception if the user has not permission to execute the method
}
}
If the user has no permission to execute the operation, the request is aborted with a 403
(Forbidden).
To know the user who is performing the request, see my previous answer. You can get it from the SecurityContext
(which should be already set in the ContainerRequestContext
) or inject it using CDI, depending on the approach you go for.
If a @Secured
annotation has no roles declared, you can assume all authenticated users can access that endpoint, disregarding the roles the users have.
Alternatively to defining the roles in the @Secured
annotation as shown above, you could consider JSR-250 annotations such as @RolesAllowed
, @PermitAll
and @DenyAll
.
JAX-RS doesn't support such annotations out-of-the-box, but it could be achieved with a filter. Here are a few considerations to keep in mind if you want to support all of them:
@DenyAll
on the method takes precedence over @RolesAllowed
and @PermitAll
on the class.@RolesAllowed
on the method takes precedence over @PermitAll
on the class.@PermitAll
on the method takes precedence over @RolesAllowed
on the class.@DenyAll
can't be attached to classes.@RolesAllowed
on the class takes precedence over @PermitAll
on the class.So an authorization filter that checks JSR-250 annotations could be like:
@Provider
@Priority(Priorities.AUTHORIZATION)
public class AuthorizationFilter implements ContainerRequestFilter {
@Context
private ResourceInfo resourceInfo;
@Override
public void filter(ContainerRequestContext requestContext) throws IOException {
Method method = resourceInfo.getResourceMethod();
// @DenyAll on the method takes precedence over @RolesAllowed and @PermitAll
if (method.isAnnotationPresent(DenyAll.class)) {
refuseRequest();
}
// @RolesAllowed on the method takes precedence over @PermitAll
RolesAllowed rolesAllowed = method.getAnnotation(RolesAllowed.class);
if (rolesAllowed != null) {
performAuthorization(rolesAllowed.value(), requestContext);
return;
}
// @PermitAll on the method takes precedence over @RolesAllowed on the class
if (method.isAnnotationPresent(PermitAll.class)) {
// Do nothing
return;
}
// @DenyAll can't be attached to classes
// @RolesAllowed on the class takes precedence over @PermitAll on the class
rolesAllowed =
resourceInfo.getResourceClass().getAnnotation(RolesAllowed.class);
if (rolesAllowed != null) {
performAuthorization(rolesAllowed.value(), requestContext);
}
// @PermitAll on the class
if (resourceInfo.getResourceClass().isAnnotationPresent(PermitAll.class)) {
// Do nothing
return;
}
// Authentication is required for non-annotated methods
if (!isAuthenticated(requestContext)) {
refuseRequest();
}
}
/**
* Perform authorization based on roles.
*
* @param rolesAllowed
* @param requestContext
*/
private void performAuthorization(String[] rolesAllowed,
ContainerRequestContext requestContext) {
if (rolesAllowed.length > 0 && !isAuthenticated(requestContext)) {
refuseRequest();
}
for (final String role : rolesAllowed) {
if (requestContext.getSecurityContext().isUserInRole(role)) {
return;
}
}
refuseRequest();
}
/**
* Check if the user is authenticated.
*
* @param requestContext
* @return
*/
private boolean isAuthenticated(final ContainerRequestContext requestContext) {
// Return true if the user is authenticated or false otherwise
// An implementation could be like:
// return requestContext.getSecurityContext().getUserPrincipal() != null;
}
/**
* Refuse the request.
*/
private void refuseRequest() {
throw new AccessDeniedException(
"You don't have permissions to perform this action.");
}
}
Note: The above implementation is based on the Jersey RolesAllowedDynamicFeature
. If you use Jersey, you don't need to write your own filter, just use the existing implementation.

I don't understand the first two answers. I think they must be version-dependent. I cannot reproduce them on MySQLdb 1.2.3, which comes with Ubuntu 14.04LTS. Let's try them. First, we verify that MySQL doesn't accept double-apostrophes:
mysql> select * from methods limit 1;
+----------+--------------------+------------+
| MethodID | MethodDescription | MethodLink |
+----------+--------------------+------------+
| 32 | Autonomous Sensing | NULL |
+----------+--------------------+------------+
1 row in set (0.01 sec)
mysql> select * from methods where MethodID = ''32'';
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '9999'' ' at line 1
Nope. Let's try the example that Mandatory posted using the query constructor inside /usr/lib/python2.7/dist-packages/MySQLdb/cursors.py
where I opened "con" as a connection to my database.
>>> search = "test"
>>> "SELECT * FROM records WHERE email LIKE '%s'" % con.literal(search)
"SELECT * FROM records WHERE email LIKE ''test''"
>>>
Nope, the double apostrophes cause it to fail. Let's try Mike Graham's first comment, where he suggests leaving off the apostrophes quoting the %s:
>>> "SELECT * FROM records WHERE email LIKE %s" % con.literal(search)
"SELECT * FROM records WHERE email LIKE 'test'"
>>>
Yep, that will work, but Mike's second comment and the documentation says that the argument to execute (processed by con.literal) must be a tuple (search,)
or a list [search]
. You can try them, but you'll find no difference from the output above.
The best answer is ksg97031's.
list.append
returns None
, since it is an in-place operation and you are assigning it back to dates_dict[key]
. So, the next time when you do dates_dict.get(key, []).append
you are actually doing None.append
. That is why it is failing. Instead, you can simply do
dates_dict.setdefault(key, []).append(date)
But, we have collections.defaultdict
for this purpose only. You can do something like this
from collections import defaultdict
dates_dict = defaultdict(list)
for key, date in cur:
dates_dict[key].append(date)
This will create a new list object, if the key
is not found in the dictionary.
Note: Since the defaultdict
will create a new list if the key is not found in the dictionary, this will have unintented side-effects. For example, if you simply want to retrieve a value for the key, which is not there, it will create a new list and return it.
Just as there are printer drivers that do not connect to a printer at all but rather write to a PDF file, analogously there are virtual audio drivers available that do not connect to a physical microphone at all but can pipe input from other sources such as files or other programs.
I hope I'm not breaking any rules by recommending free/donation software, but VB-Audio Virtual Cable should let you create a pair of virtual input and output audio devices. Then you could play an MP3 into the virtual output device and then set the virtual input device as your "microphone". In theory I think that should work.
If all else fails, you could always roll your own virtual audio driver. Microsoft provides some sample code but unfortunately it is not applicable to the older Windows XP audio model. There is probably sample code available for XP too.
Situation:
Solution:
You can use a regular expression to test for a match and capture the first two digits:
import re
for i in range(1000):
match = re.match(r'(1[56])', str(i))
if match:
print(i, 'begins with', match.group(1))
The regular expression (1[56])
matches a 1 followed by either a 5 or a 6 and stores the result in the first capturing group.
Output:
15 begins with 15
16 begins with 16
150 begins with 15
151 begins with 15
152 begins with 15
153 begins with 15
154 begins with 15
155 begins with 15
156 begins with 15
157 begins with 15
158 begins with 15
159 begins with 15
160 begins with 16
161 begins with 16
162 begins with 16
163 begins with 16
164 begins with 16
165 begins with 16
166 begins with 16
167 begins with 16
168 begins with 16
169 begins with 16
This problem has hounded me for some days now, so on finding the answer that affirmatively works with tvanfosson's answer above, I thought it would be worthwhile to emphasize the core part of the answer, and address some related catch ya's.
The core answer is this, sweet and simple:
filterContext.Result = new HttpUnauthorizedResult();
In my case I inherit from a base controller, so in each controller that inherits from it I override OnAuthorize:
protected override void OnAuthorization(AuthorizationContext filterContext)
{
base.OnAuthorization(filterContext);
YourAuth(filterContext); // do your own authorization logic here
}
The problem was that in 'YourAuth', I tried two things that I thought would not only work, but would also immediately terminate the request. Well, that is not how it works. So first, the two things that DO NOT work, unexpectedly:
filterContext.RequestContext.HttpContext.Response.Redirect("/Login"); // doesn't work!
FormsAuthentication.RedirectToLoginPage(); // doesn't work!
Not only do those not work, they don't end the request either. Which means the following:
if (!success) {
filterContext.Result = new HttpUnauthorizedResult();
}
DoMoreStuffNowThatYouThinkYourAuthorized();
Well, even with the correct answer above, the flow of logic still continues! You will still hit DoMoreStuff... within OnAuthorize. So keep that in mind (DoMore... should be in an else therefore).
But with the correct answer, while OnAuthorize flow of logic continues till the end still, after that you really do get what you expect: a redirect to your login page (if you have one set in Forms auth in your webconfig).
But unexpectedly, 1) Response.Redirect("/Login") does not work: the Action method still gets called, and 2) FormsAuthentication.RedirectToLoginPage(); does the same thing: the Action method still gets called!
Which seems totally wrong to me, particularly with the latter: who would have thought that FormsAuthentication.RedirectToLoginPage does not end the request, or do the equivalant above of what filterContext.Result = new HttpUnauthorizedResult() does?

Sometimes you can retreive the phonenumber with a USSD request to your operator. For example I can get my phonenumber by dialing *116# This can probably be done within an app, I guess, if the USSD responce somehow could be catched. Offcourse this is not a method I would recommend to use within an app that is to be distributed, the code may even differ between operators.
You can also use day names like Mon
for Monday, Tue
for Tuesday, etc. It's more human friendly.
The best you can do with Python is to obscure things.
You may be able to add some additional obscurity by encrypting part of it and decrypting it on the fly and passing it to eval(). But no matter what you do someone can break it.
None of this will stop a determined attacker from disassembling the bytecode or digging through your api with help, dir, etc.

See the python page for string literals.
Is there a way to substring a string in Python, to get a new string from the 3rd character to the end of the string?
Maybe like
myString[2:end]
?
Yes, this actually works if you assign, or bind, the name,end
, to constant singleton, None
:
>>> end = None
>>> myString = '1234567890'
>>> myString[2:end]
'34567890'
Slice notation has 3 important arguments:
Their defaults when not given are None
- but we can pass them explicitly:
>>> stop = step = None
>>> start = 2
>>> myString[start:stop:step]
'34567890'
If leaving the second part means 'till the end', if you leave the first part, does it start from the start?
Yes, for example:
>>> start = None
>>> stop = 2
>>> myString[start:stop:step]
'12'
Note that we include start in the slice, but we only go up to, and not including, stop.
When step is None
, by default the slice uses 1
for the step. If you step with a negative integer, Python is smart enough to go from the end to the beginning.
>>> myString[::-1]
'0987654321'
I explain slice notation in great detail in my answer to Explain slice notation Question.
I wrote this in an ajax view, but it is a more expansive answer giving the list of currently logged in and logged out users.
The is_authenticated
attribute always returns True
for my users, which I suppose is expected since it only checks for AnonymousUsers, but that proves useless if you were to say develop a chat app where you need logged in users displayed.
This checks for expired sessions and then figures out which user they belong to based on the decoded _auth_user_id
attribute:
def ajax_find_logged_in_users(request, client_url):
"""

.This works on Windows and Ubuntu Linux, and should work on Mac as well.
The accepted answer by Francisco Spaeth works and is easy to follow. However, I think that method of building JSON sucks! This was really driven home for me as I converted some Python to Java where I could use dictionaries and nested lists, etc. to build JSON with ridiculously greater ease.
What I really don't like is having to instantiate separate objects (and generally even name them) to build up these nestings. If you have a lot of objects or data to deal with, or your use is more abstract, that is a real pain!
I tried getting around some of that by attempting to clear and reuse temp json objects and lists, but that didn't work for me because all the puts and gets, etc. in these Java objects work by reference not value. So, I'd end up with JSON objects containing a bunch of screwy data after still having some ugly (albeit differently styled) code.
So, here's what I came up with to clean this up. It could use further development, but this should help serve as a base for those of you looking for more reasonable JSON building code:
import java.util.AbstractMap.SimpleEntry;
import java.util.ArrayList;
import java.util.List;
import org.json.simple.JSONObject;
// create and initialize an object
public static JSONObject buildObject( final SimpleEntry... entries ) {
JSONObject object = new JSONObject();
for( SimpleEntry e : entries ) object.put( e.getKey(), e.getValue() );
return object;
}
// nest a list of objects inside another
public static void putObjects( final JSONObject parentObject, final String key,
final JSONObject... objects ) {
List objectList = new ArrayList<JSONObject>();
for( JSONObject o : objects ) objectList.add( o );
parentObject.put( key, objectList );
}
Implementation example:
JSONObject jsonRequest = new JSONObject();
putObjects( jsonRequest, "parent1Key",
buildObject(
new SimpleEntry( "child1Key1", "someValue" )
, new SimpleEntry( "child1Key2", "someValue" )
)
, buildObject(
new SimpleEntry( "child2Key1", "someValue" )
, new SimpleEntry( "child2Key2", "someValue" )
)
);
For OS X 10.4.x and previous:
int i;
for (i = 0; i < [myArray count]; i++) {
id myArrayElement = [myArray objectAtIndex:i];
...do something useful with myArrayElement
}
For OS X 10.5.x (or iPhone) and beyond:
for (id myArrayElement in myArray) {
...do something useful with myArrayElement
}
You could do:
class myClass : ICloneable
{
public String test;
public object Clone()
{
return this.MemberwiseClone();
}
}
then you can do
myClass a = new myClass();
myClass b = (myClass)a.Clone();
N.B. MemberwiseClone()
Creates a shallow copy of the current System.Object.
You can use:
For example:
// simple class who output his value
class ConsoleOutput
{
public:
ConsoleOutput(int value):m_value(value) { }
int Value() const { return m_value; }
private:
int m_value;
};
// functional object
class Predicat
{
public:
void operator()(ConsoleOutput const& item)
{
std::cout << item.Value() << std::endl;
}
};
void main()
{
// fill list
std::vector<ConsoleOutput> list;
list.push_back(ConsoleOutput(1));
list.push_back(ConsoleOutput(8));
// 1) using size_t
for (size_t i = 0; i < list.size(); ++i)
{
std::cout << list.at(i).Value() << std::endl;
}
// 2) iterators + distance, for std::distance only non const iterators
std::vector<ConsoleOutput>::iterator itDistance = list.begin(), endDistance = list.end();
for ( ; itDistance != endDistance; ++itDistance)
{
// int or size_t
int const position = static_cast<int>(std::distance(list.begin(), itDistance));
std::cout << list.at(position).Value() << std::endl;
}
// 3) iterators
std::vector<ConsoleOutput>::const_iterator it = list.begin(), end = list.end();
for ( ; it != end; ++it)
{
std::cout << (*it).Value() << std::endl;
}
// 4) functional objects
std::for_each(list.begin(), list.end(), Predicat());
}
I finally found out how to do this! Basically you need to run adb shell
first and then while you're in the shell run su
, which will switch the shell to run as root!
$: adb shell
$: su
The one problem I still have is that sqlite3 is not installed so the command is not recognized.
Changing the casing to all lowercases worked for me.
You could bind the DropDownList to a data source (DataTable, List, DataSet, SqlDataSource, etc).
For example, if you wanted to use a DataTable:
ddlSubject.DataSource = subjectsTable;
ddlSubject.DataTextField = "SubjectNamne";
ddlSubject.DataValueField = "SubjectID";
ddlSubject.DataBind();
EDIT - More complete example
private void LoadSubjects()
{
DataTable subjects = new DataTable();
using (SqlConnection con = new SqlConnection(connectionString))
{
try
{
SqlDataAdapter adapter = new SqlDataAdapter("SELECT SubjectID, SubjectName FROM Students.dbo.Subjects", con);
adapter.Fill(subjects);
ddlSubject.DataSource = subjects;
ddlSubject.DataTextField = "SubjectNamne";
ddlSubject.DataValueField = "SubjectID";
ddlSubject.DataBind();
}
catch (Exception ex)
{
// Handle the error
}
}
// Add the initial item - you can add this even if the options from the
// db were not successfully loaded
ddlSubject.Items.Insert(0, new ListItem("<Select Subject>", "0"));
}
To set an initial value via the markup, rather than code-behind, specify the option(s) and set the AppendDataBoundItems attribute to true:
<asp:DropDownList ID="ddlSubject" runat="server" AppendDataBoundItems="true">
<asp:ListItem Text="<Select Subject>" Value="0" />
</asp:DropDownList>
You could then bind the DropDownList to a DataSource in the code-behind (just remember to remove:
ddlSubject.Items.Insert(0, new ListItem("<Select Subject>", "0"));
from the code-behind, or you'll have two "" items.
You can do this with background-size
:
html {
background: url(images/bg.jpg) no-repeat center center fixed;
background-size: cover;
}
There are a lot of values other than cover
that you can set background-size
to, see which one works for you: https://developer.mozilla.org/en-US/docs/Web/CSS/background-size
Spec: https://www.w3.org/TR/css-backgrounds-3/#the-background-size
It works in all modern browsers: http://caniuse.com/#feat=background-img-opts
A reboot of my laptop and then
npm install
worked for me!
this type of error generally occurs when you have to put characters or values more than that you have specified in Database table like in this case:
you specify
transaction_status varchar(10)
but you actually trying to store
_transaction_status
which contain 19 characters.
that's why you faced this type of error in this code..
Generate the range of data first and then shuffle it like this
import random
data = range(numLow, numHigh)
random.shuffle(data)
print data
By doing this way, you will get all the numbers in the particular range but in a random order.
But you can use random.sample
to get the number of elements you need, from a range of numbers like this
print random.sample(range(numLow, numHigh), 3)
I found a short comparison from MSDN
The .NET Framework Class Library includes four classes named Timer, each of which offers different functionality:
System.Timers.Timer
, which fires an event and executes the code in one or more event sinks at regular intervals. The class is intended for use as a server-based or service component in a multithreaded environment; it has no user interface and is not visible at runtime.
System.Threading.Timer
, which executes a single callback method on a thread pool thread at regular intervals. The callback method is defined when the timer is instantiated and cannot be changed. Like the System.Timers.Timer class, this class is intended for use as a server-based or service component in a multithreaded environment; it has no user interface and is not visible at runtime.
System.Windows.Forms.Timer
, a Windows Forms component that fires an event and executes the code in one or more event sinks at regular intervals. The component has no user interface and is designed for use in a single-threaded environment.
System.Web.UI.Timer
, an ASP.NET component that performs asynchronous or synchronous web page postbacks at a regular interval.
Although this is an "old" thread, I still would like to add the following to it:
I've experienced the next case:
int SetI2cSlaveAddress( UCHAR addr, bool force );
int CI2cHal::SetI2cSlaveAddress( UCHAR addr, bool force = false ) { ... }
As one can see, I had put the default value of the parameter "force" in the class source file, not in the class header file.
Then I used that function in a derived class as follows (derived class inherited the base class in a public way):
SetI2cSlaveAddress( addr );
assuming it would take the "force" parameter as "false" 'for granted'.
However, the compiler (put in c++11 mode) complained and gave me the following compiler error:
/home/.../mystuff/domoproject/lib/i2cdevs/max6956io.cpp: In member function 'void CMax6956Io::Init(unsigned char, unsigned char, unsigned int)':
/home/.../mystuff/domoproject/lib/i2cdevs/max6956io.cpp:26:30: error: no matching function for call to 'CMax6956Io::SetI2cSlaveAddress(unsigned char&)'
/home/.../mystuff/domoproject/lib/i2cdevs/max6956io.cpp:26:30: note: candidate is:
In file included from /home/geertvc/mystuff/domoproject/lib/i2cdevs/../../include/i2cdevs/max6956io.h:35:0,

/home/.../mystuff/domoproject/lib/i2cdevs/../../include/i2chal/i2chal.h:65:9: note: int CI2cHal::SetI2cSlaveAddress(unsigned char, bool)

make[1]: *** [lib/i2cdevs/CMakeFiles/i2cdevs.dir/all] Error 2
make: *** [all] Error 2
But when I added the default parameter in the header file of the base class:
int SetI2cSlaveAddress( UCHAR addr, bool force = false );
and removed it from the source file of the base class:
int CI2cHal::SetI2cSlaveAddress( UCHAR addr, bool force )
then the compiler was happy and all code worked as expected (I could give one or two parameters to the function SetI2cSlaveAddress()
)!
So, not only for the user of a class it's important to put the default value of a parameter in the header file, also compiling and functional wise it apparently seems to be a must!
Declare the parameter in test.ps1:
Param(
[Parameter(Mandatory=$True,Position=1)]
[string]$input_dir,
[Parameter(Mandatory=$True)]
[string]$output_dir,
[switch]$force = $false
)
Run the script from Run OR Windows Task Scheduler:
powershell.exe -command "& C:\FTP_DATA\test.ps1 -input_dir C:\FTP_DATA\IN -output_dir C:\FTP_DATA\OUT"
or,
powershell.exe -command "& 'C:\FTP DATA\test.ps1' -input_dir 'C:\FTP DATA\IN' -output_dir 'C:\FTP DATA\OUT'"
If you clone with the --depth
parameter, it sets .git/config
not to fetch all branches, but only master.
You can simply omit the parameter or update the configuration file from
fetch = +refs/heads/master:refs/remotes/origin/master
to
fetch = +refs/heads/*:refs/remotes/origin/*
The SQL is somewhat like the syntax of MS SQL.
SELECT * FROM [table$] WHERE *;
It is important that the table name is ended with a $ sign and the whole thing is put into brackets. As conditions you can use any value, but so far Excel didn't allow me to use what I call "SQL Apostrophes" (´), so a column title in one word is recommended.
If you have users listed in a table called "Users", and the id is in a column titled "id" and the name in a column titled "Name", your query will look like this:
SELECT Name FROM [Users$] WHERE id = 1;
Hope this helps.

Finally, the wait is over with SQL Server 2016. They have introduced the Split string function, STRING_SPLIT
:
select OtherID, cs.Value --SplitData
from yourtable
cross apply STRING_SPLIT (Data, ',') cs
All the other methods to split string like XML, Tally table, while loop, etc.. have been blown away by this STRING_SPLIT
function.
Here is an excellent article with performance comparison: Performance Surprises and Assumptions: STRING_SPLIT.
For older versions, using tally table here is one split string function(best possible approach)
CREATE FUNCTION [dbo].[DelimitedSplit8K]
(@pString VARCHAR(8000), @pDelimiter CHAR(1))
RETURNS TABLE WITH SCHEMABINDING AS
RETURN
--===== "Inline" CTE Driven "Tally Table" produces values from 0 up to 10,000...
-- enough to cover NVARCHAR(4000)
WITH E1(N) AS (
SELECT 1 UNION ALL SELECT 1 UNION ALL SELECT 1 UNION ALL
SELECT 1 UNION ALL SELECT 1 UNION ALL SELECT 1 UNION ALL
SELECT 1 UNION ALL SELECT 1 UNION ALL SELECT 1 UNION ALL SELECT 1
), --10E+1 or 10 rows
E2(N) AS (SELECT 1 FROM E1 a, E1 b), --10E+2 or 100 rows
E4(N) AS (SELECT 1 FROM E2 a, E2 b), --10E+4 or 10,000 rows max
cteTally(N) AS (--==== This provides the "base" CTE and limits the number of rows right up front
-- for both a performance gain and prevention of accidental "overruns"
SELECT TOP (ISNULL(DATALENGTH(@pString),0)) ROW_NUMBER() OVER (ORDER BY (SELECT NULL)) FROM E4
),
cteStart(N1) AS (--==== This returns N+1 (starting position of each "element" just once for each delimiter)
SELECT 1 UNION ALL
SELECT t.N+1 FROM cteTally t WHERE SUBSTRING(@pString,t.N,1) = @pDelimiter
),
cteLen(N1,L1) AS(--==== Return start and length (for use in substring)
SELECT s.N1,
ISNULL(NULLIF(CHARINDEX(@pDelimiter,@pString,s.N1),0)-s.N1,8000)
FROM cteStart s
)
--===== Do the actual split. The ISNULL/NULLIF combo handles the length for the final element when no delimiter is found.
SELECT ItemNumber = ROW_NUMBER() OVER(ORDER BY l.N1),
Item = SUBSTRING(@pString, l.N1, l.L1)
FROM cteLen l

In config.inc.php
in the top-level directory, set
$cfg['DefaultLang'] = 'en-utf-8'; // Language if no other language is recognized
// or
$cfg['Lang'] = 'en-utf-8'; // Force this language for all users
If Lang
isn't set, you should be able to select the language in the initial welcome screen, and the language your browser prefers should be preselected there.
Printing the exception's stack trace in itself doesn't constitute bad practice, but only printing the stace trace when an exception occurs is probably the issue here -- often times, just printing a stack trace is not enough.
Also, there's a tendency to suspect that proper exception handling is not being performed if all that is being performed in a catch
block is a e.printStackTrace
. Improper handling could mean at best an problem is being ignored, and at worst a program that continues executing in an undefined or unexpected state.
Example
Let's consider the following example:
try {
initializeState();
} catch (TheSkyIsFallingEndOfTheWorldException e) {
e.printStackTrace();
}
continueProcessingAssumingThatTheStateIsCorrect();
Here, we want to do some initialization processing before we continue on to some processing that requires that the initialization had taken place.
In the above code, the exception should have been caught and properly handled to prevent the program from proceeding to the continueProcessingAssumingThatTheStateIsCorrect
method which we could assume would cause problems.
In many instances, e.printStackTrace()
is an indication that some exception is being swallowed and processing is allowed to proceed as if no problem every occurred.
Why has this become a problem?
Probably one of the biggest reason that poor exception handling has become more prevalent is due to how IDEs such as Eclipse will auto-generate code that will perform a e.printStackTrace
for the exception handling:
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
(The above is an actual try-catch
auto-generated by Eclipse to handle an InterruptedException
thrown by Thread.sleep
.)
For most applications, just printing the stack trace to standard error is probably not going to be sufficient. Improper exception handling could in many instances lead to an application running in a state that is unexpected and could be leading to unexpected and undefined behavior.
If you would like to redirect the user after the alert, do this:
echo ("<script LANGUAGE='JavaScript'>
window.alert('Succesfully Updated');
window.location.href='<URL to redirect to>';
</script>");
