On MySQL 8.0.4+
To update current root user:
select current_user();
set password = 'new_password';
To update other user:
set password for 'otherUser'@'localhost' = 'new_password';
To set password policy before updating password:
set global validate_password.policy = 0;
set password = 'new_password';
set password for 'otherUser'@'localhost' = 'new_password';
Other / better way to update root password:
mysql_secure_installation
Want to stick with 5.x authentication so you can still use legacy apps?
On my.cnf
default_authentication_plugin = mysql_native_password
To update root:
set global validate_password.policy = 0;
alter user 'root'@'localhost' identified with mysql_native_password by 'new_password';
Simple answer: (watch for blank & null)
isNaN(+'111') = false;
isNaN(+'111r') = true;
isNaN(+'r') = true;
isNaN(+'') = false;
isNaN(null) = false;
If you would like to support really old browsers you should parse the date string, since using the ISO8601 date format with the Date
constructor is not supported pre IE9:
var queryDate = '2009-11-01',
dateParts = queryDate.match(/(\d+)/g)
realDate = new Date(dateParts[0], dateParts[1] - 1, dateParts[2]);
// months are 0-based!
// For >= IE9
var realDate = new Date('2009-11-01');
$('#datePicker').datepicker({ dateFormat: 'yy-mm-dd' }); // format to show
$('#datePicker').datepicker('setDate', realDate);
Check the above example here.
I can do like that (sorry it's c# not java but it's not a problem...) :
private int iValue = 1234567890;
function void MyTest()
{
Intent oIntent = new Intent (this, typeof(Camera2Activity));
Bundle oBundle = new Bundle();
oBundle.PutInt("MYVALUE", iValue); //=> 1234567890
oIntent.PutExtras (oBundle);
iRequestCode = 1111;
StartActivityForResult (oIntent, 1111);
}
AND IN YOUR ACTIVITY FOR RESULT
private int iValue = 0;
protected override void OnCreate(Bundle bundle)
{
Bundle oBundle = Intent.Extras;
if (oBundle != null)
{
iValue = oBundle.GetInt("MYVALUE", 0);
//=>1234567890
}
}
private void FinishActivity(bool bResult)
{
Intent oIntent = new Intent();
Bundle oBundle = new Bundle();
oBundle.PutInt("MYVALUE", iValue);//=>1234567890
oIntent.PutExtras(oBundle);
if (bResult)
{
SetResult (Result.Ok, oIntent);
}
else
SetResult(Result.Canceled, oIntent);
GC.Collect();
Finish();
}
FINALLY
protected override void OnActivityResult(int iRequestCode, Android.App.Result oResultCode, Intent oIntent)
{
base.OnActivityResult (iRequestCode, oResultCode, oIntent);
iValue = oIntent.Extras.GetInt("MYVALUE", -1); //=> 1234567890
}
I think the $() syntax is easier to read...
variable=$(ps -ef | grep "port 10 -" | grep -v "grep port 10 -"| awk '{printf "%s", $12}')
But the real issue is probably that $12
should not be qouted with ""
Edited since the question was changed, This returns valid data, but it is not clear what the expected output of ps -ef
is and what is expected in variable.
Well the syntax is almost the same but they rely on different frameworks so the only way to convert is by getting someone who knows both languages and convert the code :) the answer to your question is no there is no "effective" tool to convert c# to java
One more option is require-dir-all combining features from most popular packages.
Most popular require-dir
does not have options to filter the files/dirs and does not have map
function (see below), but uses small trick to find module's current path.
Second by popularity require-all
has regexp filtering and preprocessing, but lacks relative path, so you need to use __dirname
(this has pros and contras) like:
var libs = require('require-all')(__dirname + '/lib');
Mentioned here require-index
is quite minimalistic.
With map
you may do some preprocessing, like create objects and pass config values (assuming modules below exports constructors):
// Store config for each module in config object properties
// with property names corresponding to module names
var config = {
module1: { value: 'config1' },
module2: { value: 'config2' }
};
// Require all files in modules subdirectory
var modules = require('require-dir-all')(
'modules', // Directory to require
{ // Options
// function to be post-processed over exported object for each require'd module
map: function(reqModule) {
// create new object with corresponding config passed to constructor
reqModule.exports = new reqModule.exports( config[reqModule.name] );
}
}
);
// Now `modules` object holds not exported constructors,
// but objects constructed using values provided in `config`.
If it is something to do with the data in your database, why not utilize database isolation locking to achieve?
If you're doing this to several fields, or doing it quite often, then perhaps a plugin is the answer.
Here's the beginnings of a jQuery plugin that formats the value of a field to two decimal places.
It is triggered by the onchange event of the field. You may want something different.
<script type="text/javascript">
// mini jQuery plugin that formats to two decimal places
(function($) {
$.fn.currencyFormat = function() {
this.each( function( i ) {
$(this).change( function( e ){
if( isNaN( parseFloat( this.value ) ) ) return;
this.value = parseFloat(this.value).toFixed(2);
});
});
return this; //for chaining
}
})( jQuery );
// apply the currencyFormat behaviour to elements with 'currency' as their class
$( function() {
$('.currency').currencyFormat();
});
</script>
<input type="text" name="one" class="currency"><br>
<input type="text" name="two" class="currency">
Try CSS:
<h2 style="color:#069">Process Report</h2>
If you have more than one h2 tags which should have the same color add a style tag to the head tag like this:
<style type="text/css">
h2 {
color:#069;
}
</style>
Open port 9418 on your firewall - it's a custom port that Git uses to communicate on and it's often not open on a corporate or private firewall.
Bootstrap now has the following style for table cells:
.table tbody > tr > td{
vertical-align: top;
}
The way to go is to add your own class, adding more specificity to the previous selector:
.table tbody > tr > td.vert-aligned {
vertical-align: middle;
}
And then add the class to your td
s:
<tr>
<td class="vert-aligned"></td>
...
</tr>
There is no way to do this with Bootstrap.
When used in table cells, vertical-align does what most people expect it to, which is to mimic the (old, deprecated) valign attribute. In a modern, standards-compliant browser, the following three code snippets do the same thing:
<td valign="middle"> <!-- but you shouldn't ever use valign --> </td>
<td style="vertical-align:middle"> ... </td>
<div style="display:table-cell; vertical-align:middle"> ... </div>
Check your fiddle updated
Also, you can't refer to the td
class using .vert
because Bootstrap already has this class:
.table td {
padding: 8px;
line-height: 20px;
text-align: left;
vertical-align: top; // The problem!
border-top: 1px solid #dddddd;
}
And is overloading the vertical-align: middle
in '.vert' class, so you have to define this class as td.vert
.
This is how I do it:
public static String readFromAssets(Context context, String filename) throws IOException {
BufferedReader reader = new BufferedReader(new InputStreamReader(context.getAssets().open(filename)));
// do reading, usually loop until end of file reading
StringBuilder sb = new StringBuilder();
String mLine = reader.readLine();
while (mLine != null) {
sb.append(mLine); // process line
mLine = reader.readLine();
}
reader.close();
return sb.toString();
}
use it as follows:
readFromAssets(context,"test.txt")
using System.IO;
...
foreach (string file in Directory.EnumerateFiles(folderPath, "*.xml"))
{
string contents = File.ReadAllText(file);
}
Note the above uses a .NET 4.0 feature; in previous versions replace EnumerateFiles
with GetFiles
). Also, replace File.ReadAllText
with your preferred way of reading xml files - perhaps XDocument
, XmlDocument
or an XmlReader
.

http://www.postgresql.org/docs/current/static/functions-datetime.html shows operators you can use for working with dates and times (and intervals).
So you want
SELECT "date"
FROM "Table"
WHERE "date" > (CURRENT_DATE - INTERVAL '10 days');
The operators/functions above are documented in detail:
This error can be due to many many things.
The key here seems the hint about error reading
. I see you are working on a flash drive or something similar? Try to run the install on a local folder owned by your current user.
You could also try with sudo
, that might solve a permission problem if that's the case.
Another reason why it cannot read could be because it has not downloaded correctly, or saved correctly. A little problem in your network could have caused that, and the cache clean would remove the files and force a refetch but that does not solve your problem. That means it would be more on the save part, maybe it didn't save because of permissions, maybe it didn't not save correctly because it was lacking disk space...
You could also wrap the transaction up into it's own stored procedure and handle it that way instead of doing transactions in C# itself.
Add the jar files to your library(if using netbeans) and modify your manifest's file classpath
as follows:
Class-Path: lib/derby.jar lib/derbyclient.jar lib/derbynet.jar lib/derbytools.jar
a similar answer exists here
Depending on the libc release it could be needed to set both SO_REUSEADDR and SO_REUSEPORT socket options as explained in socket(7) documentation :
SO_REUSEPORT (since Linux 3.9) Permits multiple AF_INET or AF_INET6 sockets to be bound to an identical socket address. This option must be set on each socket (including the first socket) prior to calling bind(2) on the socket. To prevent port hijacking, all of the processes binding to the same address must have the same effective UID. This option can be employed with both TCP and UDP sockets.
As this socket option appears with kernel 3.9 and raspberry use 3.12.x, it will be needed to set SO_REUSEPORT.
You can set theses two options before calling bind like this :
int reuse = 1;
if (setsockopt(sockfd, SOL_SOCKET, SO_REUSEADDR, (const char*)&reuse, sizeof(reuse)) < 0)
perror("setsockopt(SO_REUSEADDR) failed");
#ifdef SO_REUSEPORT
if (setsockopt(sockfd, SOL_SOCKET, SO_REUSEPORT, (const char*)&reuse, sizeof(reuse)) < 0)
perror("setsockopt(SO_REUSEPORT) failed");
#endif
Why all the other answers use slideUp
is just beyond me. As I'm using the fade
and in
classes to have the alert fade away when closed (or after timeout), I don't want it to "slide up" and conflict with that.
Besides the slideUp
method didn't even work. The alert itself didn't show at all. Here's what worked perfectly for me:
$(document).ready(function() {
// show the alert
setTimeout(function() {
$(".alert").alert('close');
}, 2000);
});
I do not think the warnings you have received are related. I had the same warnings which turned out to be the chrome extension React Dev Tools. Removed the extension and the errors have gone.

Java infers automatically the type of the elements in case
, so the labels must be unqualified.
int i;
switch(i) {
case 5: // <- integer is expected
}
MyEnum e;
switch (e) {
case VALUE_A: // <- an element of the enumeration is expected
}
I came here looking for a possible explanation before taking a closer look at the lines preceding the linker error. It turned out to have been an additional executable for which the global declaration was missing!
In Ubuntu systems running MySQL 5.7 (and later versions), the root MySQL user is set to authenticate using the auth_socket plugin by default rather than with a password. This allows for some greater security and usability in many cases, but it can also complicate things when you need to allow an external program (e.g., phpMyAdmin) to access the user.
If you prefer to use a password when connecting to MySQL as root, you will need to switch its authentication method from auth_socket to mysql_native_password. source
Open up the MySQL prompt from your terminal:
$ sudo mysql
Next, check which authentication method each of your MySQL user accounts use with the following command:
mysql > SELECT user,authentication_string,plugin,host FROM mysql.user;
You will see that the root user does in fact authenticate using the auth_socket plugin. To configure the root account to authenticate with a password, run the following ALTER USER
command. Be sure to change password to a strong password of your choosing:
mysql > ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password';
Then, run FLUSH PRIVILEGES
which tells the server to reload the grant tables and put your new changes into effect:
mysql > FLUSH PRIVILEGES;
Check the authentication methods employed by each of your users again to confirm that root no longer authenticates using the auth_socket plugin:
mysql > SELECT user,authentication_string,plugin,host FROM mysql.user;
You will see in output that the root MySQL user now authenticates using a password.
You could use ResolverUtil (raw source) from the Stripes Framework
if you need something simple and quick without refactoring any existing code.
Here's a simple example not having loaded any of the classes:
package test;
import java.util.Set;
import net.sourceforge.stripes.util.ResolverUtil;
public class BaseClassTest {
public static void main(String[] args) throws Exception {
ResolverUtil<Animal> resolver = new ResolverUtil<Animal>();
resolver.findImplementations(Animal.class, "test");
Set<Class<? extends Animal>> classes = resolver.getClasses();
for (Class<? extends Animal> clazz : classes) {
System.out.println(clazz);
}
}
}
class Animal {}
class Dog extends Animal {}
class Cat extends Animal {}
class Donkey extends Animal {}
This also works in an application server as well since that's where it was designed to work ;)
The code basically does the following:
ClassLoader#loadClass(String fullyQualifiedName)
Animal.class.isAssignableFrom(loadedClass);
force it with -l
sudo umount -l ${HOME}/mount_dir
for a monthpicker, using JQuery v 1.7.2, I have the following javascript which is doing just that
$l("[id$=txtDtPicker]").monthpicker({
showOn: "both",
buttonImage: "../../images/Calendar.png",
buttonImageOnly: true,
pattern: 'yyyymm', // Default is 'mm/yyyy' and separator char is not mandatory
monthNames: ['Jan', 'Fev', 'Mar', 'Abr', 'Mai', 'Jun', 'Jul', 'Ago', 'Set', 'Out', 'Nov', 'Dez']
});
If you have set the ANDROID_HOME variable, just remove or comment that line in local.properties file. It is the solution for me
If you're in netbeans you can right click in the test method and click "Run Focused Test Method".
I've been a Vim user for years. I'm starting to find myself starting up Eclipse occasionally (using the vi plugin, which, I have to say, has a variety of issues). The main reason is that Java builds take quite a while...and they are just getting slower and slower with the addition of highly componentized build-frameworks like maven. So validating your changes tends to take quite a while, which for me seems to often lead to stacking up a bunch of compile issues I have to resolve later, and filtering through the commit messages takes a while.
When I get too big of a queue of compile issues, I fire up Eclipse. It lets me make cake-work of the changes. It's slow, brutal to use, and not nearly as nice of an editor as Vim is (I've been using Vim for nearly a decade, so it's second nature to me). I find for precision editing—needing to fix a specific bug, needing to refactor some specific bit of logic, or something else...I simply can't be as efficient at editing in Eclipse as I can in Vim.
Also a tip:
:set path=**
:chdir your/project/root
This makes ^wf
on a classname a very nice feature for navigating a large project.
So anyway, the skinny is, when I need to add a lot of new code, Vim seems to slow me down simply due to the time spent chasing down compilation issues and similar stuff. When I need to find and edit specific sources, though, Eclipse feels like a sledge hammer. I'm still waiting for the magical IDE for Vim. There's been three major attempts I know of. There's a pure viml IDE-type plugin which adds a lot of features but seems impossible to use. There's eclim, which I've had a lot of trouble with. And there's a plugin for Eclipse which actually embeds Vim. The last one seems the most promising for real serious Java EE work, but it doesn't seem to work very well or really integrate all of Eclipse's features with the embedded Vim.
Things like add a missing import with a keystroke, hilight code with typing issues, etc, seems to be invaluable from your IDE when working on a large Java project.
In my case, I was trying to use mdbreact on windows. Though it installed, But i was getting the above error. I had to reinstall it and everything was ok. It happened to me once two with antd Library
You can look up the constraint name in the sys.key_constraints table:
SELECT name
FROM sys.key_constraints
WHERE [type] = 'PK'
AND [parent_object_id] = Object_id('dbo.Student');
If you don't care about the name, but simply want to drop it, you can use a combination of this and dynamic sql:
DECLARE @table NVARCHAR(512), @sql NVARCHAR(MAX);
SELECT @table = N'dbo.Student';
SELECT @sql = 'ALTER TABLE ' + @table
+ ' DROP CONSTRAINT ' + name + ';'
FROM sys.key_constraints
WHERE [type] = 'PK'
AND [parent_object_id] = OBJECT_ID(@table);
EXEC sp_executeSQL @sql;
This code is from Aaron Bertrand (source).
Node.js uses the environmental variable NODE_PATH
to allow for specifying additional directories to include in the module search path. You can use npm
itself to tell you where global modules are stored with the npm root -g
command. So putting those two together, you can make sure global modules are included in your search path with the following command (on Linux-ish)
export NODE_PATH=$(npm root --quiet -g)
Jupytext is nice to have in your toolchain for such conversions. It allows not only conversion from a notebook to a script, but you can go back again from the script to notebook as well. And even have that notebook produced in executed form.
jupytext --to py notebook.ipynb # convert notebook.ipynb to a .py file
jupytext --to notebook notebook.py # convert notebook.py to an .ipynb file with no outputs
jupytext --to notebook --execute notebook.py # convert notebook.py to an .ipynb file and run it
I know, that's the "answer" nobody wants. But if something's worth doing, it's worth doing right, right?
This seeming like a good idea probably stems from a fairly wide misconception that shell commands such as curl
are anything other than programs themselves.
So what you're asking is "how do I run this other program, from within my program, just to make a measly little web request?". That's crazy, there's got to be a better way right?
Uxio's answer works, sure. But it hardly looks very Pythonic, does it? That's a lot of work just for one little request. Python's supposed to be about flying! Anyone writing that is probably wishing they just call
'd curl
!
it works, but is there a better way?
Things shouldn’t be this way. Not in Python.
Let's GET this page:
import requests
res = requests.get('https://stackoverflow.com/questions/26000336')
That's it, really! You then have the raw res.text
, or res.json()
output, the res.headers
, etc.
You can see the docs (linked above) for details of setting all the options, since I imagine OP has moved on by now, and you - the reader now - likely need different ones.
But, for example, it's as simple as:
url = 'http://example.tld'
payload = { 'key' : 'val' }
headers = {}
res = requests.post(url, data=payload, headers=headers)
You can even use a nice Python dict to supply the query string in a GET request with params={}
.
Simple and elegant. Keep calm, and fly on.
Your connection string is wrong
<connectionStrings>
<add name="ConnStringDb1" connectionString="Data Source=localhost\SQLSERVER;Initial Catalog=YourDataBaseName;Integrated Security=True;" providerName="System.Data.SqlClient" />
</connectionStrings>
array_slice
returns a slice of an array
$sliced_array = array_slice($array, 0, 5)
is the code you want in your case to return the first five elements
You cannot really find the display resolution from a web page. There is a CSS Media Queries statement for it, but it is poorly implemented in most devices and browsers, if at all. However, you do not need to know the resolution of the display, because changing it causes the (pixel) width of the window to change, which can be detected using the methods others have described:
$(window).resize(function() {
// This will execute whenever the window is resized
$(window).height(); // New height
$(window).width(); // New width
});
You can also use CSS Media Queries in browsers that support them to adapt your page's style to various display widths, but you should really be using em
units and percentages and min-width
and max-width
in your CSS if you want a proper flexible layout. Gmail probably uses a combination of all these.
JSONArray jsonArray = new JSONArray(yourJsonString);
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject obj1 = jsonArray.getJSONObject(i);
JSONArray results = patient.getJSONArray("results");
String indexForPhone = patientProfile.getJSONObject(0).getString("indexForPhone"));
}
Change to JSONArray, then convert to JSONObject.
We can use attribute selector in DOM by using document.querySelector()
and document.querySelectorAll()
methods.
for yours:
document.querySelector("[myAttribute='aValue']");
and by using querySelectorAll()
:
document.querySelectorAll("[myAttribute='aValue']");
In querySelector()
and querySelectorAll()
methods we can select objects as we select in "CSS".
More about "CSS" attribute selectors in https://developer.mozilla.org/en-US/docs/Web/CSS/Attribute_selectors
I know this is an old question and that an HTML page with multiple IDs is invalid. However, I ran into this issues while needing to scrape and reformat someone else's API's HTML documentation that contained duplicate IDs (invalid HTML).
So for anyone else, here is the code I used to work around the issue using querySelectorAll:
var elms = document.querySelectorAll("[id='duplicateID']");
for(var i = 0; i < elms.length; i++)
elms[i].style.display='none'; // <-- whatever you need to do here.
Whenever this happens the first thing I check is the PHP memory limit.
Magento overrides the normal error handler with it's own, but when the error is "Out of memory" that custom handler cannot run, so nothing is seen.
Try an OUTER APPLY
SELECT
C.Content_ID,
C.Content_Title,
C.Content_DatePublished,
M.Media_Id
FROM
tbl_Contents C
OUTER APPLY
(
SELECT TOP 1 *
FROM tbl_Media M
WHERE M.Content_Id = C.Content_Id
) m
ORDER BY
C.Content_DatePublished ASC
Alternatively, you could GROUP BY
the results
SELECT
C.Content_ID,
C.Content_Title,
C.Content_DatePublished,
M.Media_Id
FROM
tbl_Contents C
LEFT OUTER JOIN tbl_Media M ON M.Content_Id = C.Content_Id
GROUP BY
C.Content_ID,
C.Content_Title,
C.Content_DatePublished,
M.Media_Id
ORDER BY
C.Content_DatePublished ASC
The OUTER APPLY
selects a single row (or none) that matches each row from the left table.
The GROUP BY
performs the entire join, but then collapses the final result rows on the provided columns.
For postgres, I found it easier and more accurate to use the
function, like:
select name, sum(count), date_trunc('minute',timestamp) as timestamp
FROM table
WHERE xxx
GROUP BY name,date_trunc('minute',timestamp)
ORDER BY timestamp
You can provide various resolutions like 'minute','hour','day' etc... to date_trunc.
You could also create a trigger that will calculate the sum before each insert
delimiter |
CREATE TRIGGER calCumluativeSum BEFORE INSERT ON someTable
FOR EACH ROW BEGIN
SET cumulative_sum = (
SELECT SUM(x.count)
FROM someTable x
WHERE x.id <= NEW.id
)
set NEW.cumulative_sum = cumulative_sum;
END;
|
I have not tested this
I don't think a message box is the best way to go with this as you would need the VB code running in a loop to check the cell contents, or unless you plan to run the macro manually. In this case I think it would be better to add conditional formatting to the cell to change the background to red (for example) if the value exceeds the upper limit.
Run dos2unix or similar utility on it to remove the carriage returns (^M).
This message indicates that your file has dos-style lineendings:
-bash: /backup/backup.sh: /bin/bash^M: bad interpreter: No such file or directory
Utilities like dos2unix
will fix it:
dos2unix <backup.bash >improved-backup.sh
Or, if no such utility is installed, you can accomplish the same thing with translate:
tr -d "\015\032" <backup.bash >improved-backup.sh
As for how those characters got there in the first place, @MadPhysicist had some good comments.
If using Struts, we disable direct access to the JSP files by using this tag in web.xml
<security-constraint>
<web-resource-collection>

</web-resource-collection>
<auth-constraint/>
One other way to work around this is using something like this when using mysqlclient in python.
suppose the data you want to enter is like this <ol><li><strong style="background-color: rgb(255, 255, 0);">Saurav\'s List</strong></li></ol>
. It contains both double qoute and single quote.
You can use the following method to escape the quotes:
statement = """ Update chats set html='{}' """.format(html_string.replace("'","\\\'"))
Note: three \ characters are needed to escape the single quote which is there in unformatted python string.
You need to add some arguments. Also, instancing and opening can be put in one line:
fstream file("test.txt", fstream::in | fstream::out | fstream::trunc);
Also check that your server isn't setting secure cookies on a non http request. Just found out that my ajax request was getting a php session with "secure" set. Because I was not on https it was not sending back the session cookie and my session was getting reset on each ajax request.
i did this by adding some letter in my main document and made it transparent and assigned the font that I wanted to load.
e.g.
<p>normal text from within page here and then followed by:
<span style="font-family:'Arial Rounded Bold'; color:transparent;">t</span>
</p>
If you haven't made a backup, you are pretty much fudged.
I manage to find the answer for this solution, have to do javascript injection for this to install atob
const atob:any = require('atob');
asn1(pem: any){
asn1parser.Enc.base64ToBuf = function (b64:any) {
return asn1parser.Enc.binToBuf(atob(b64));
};
const dertest = asn1parser.PEM.parseBlock(pem).der;
var hex = asn1parser.Enc.bufToHex(asn1parser.PEM.parseBlock(pem).der)
var buf = asn1parser.ASN1.parse(dertest);
var asn1 = JSON.stringify(asn1parser.ASN1.parse(dertest), asn1parser.ASN1._replacer, 2 );
Similar error with Glassfish 4.0 and several JDK installed:
SEVERE: GlassFish requires JDK 7, you are using JDK version 6.
There is no AS_JAVA reference in "C:\glassfish\config\asenv.bat" by default. After adding manually
set AS_JAVA=C:\Program Files\Java\jdk1.7.0_25
it works.
You want to do $arrayOfString[0].Title -eq $myPbiject.item(0).Title
-match
is for regex matching ( the second argument is a regex )
You are probably looking for 'chr()':
>>> L = [104, 101, 108, 108, 111, 44, 32, 119, 111, 114, 108, 100]
>>> ''.join(chr(i) for i in L)
'hello, world'
Try add !important to your css. Its working for me.
.panel {
float: right;
width: 120px;
height: auto;
background: #fff;
border-radius: 7px!important;
}
Right now, you're creating an instance of every type defined in the assembly. You only need to create a single instance of Class1
in order to call the method:
class Program
{
static void Main(string[] args)
{
var DLL = Assembly.LoadFile(@"C:\visual studio 2012\Projects\ConsoleApplication1\ConsoleApplication1\DLL.dll");
var theType = DLL.GetType("DLL.Class1");
var c = Activator.CreateInstance(theType);
var method = theType.GetMethod("Output");
method.Invoke(c, new object[]{@"Hello"});
Console.ReadLine();
}
}
Have both buttons submit to the current page and then add this code at the top:
<?php
if(isset($_GET['firstButtonName'])
header("Location: first-target.php?var1={$_GET['var1']}&var2={$_GET['var2']}");
if(isset($_GET['secondButtonName'])
header("Location: second-target.php?var1={$_GET['var1']}&var2={$_GET['var2']}");
?>
It could also be done using $_SESSION if you don't want them to see the variables.
Scape slashes is simply use \
before /
and it will be escaped. (\/
=> /
).
Otherwise you're regex DD/MM/YYYY could be next:
/^[0-9]{2}[\/]{1}[0-9]{2}[\/]{1}[0-9]{4}$/g
[0-9]
: Just Numbers{2}
or {4}
: Length 2 or 4. You could do {2,4}
as well to length between two numbers (2 and 4 in this case)[\/]
: Character /
g
: Global -- Or m
: Multiline (Optional, see your requirements)$
: Anchor to end of string. (Optional, see your requirements)^
: Start of string. (Optional, see your requirements)An example of use:
var regex = /^[0-9]{2}[\/][0-9]{2}[\/][0-9]{4}$/g;
var dates = ["2009-10-09", "2009.10.09", "2009/10/09", "200910-09", "1990/10/09",
"2016/0/09", "2017/10/09", "2016/09/09", "20/09/2016", "21/09/2016", "22/09/2016",
"23/09/2016", "19/09/2016", "18/09/2016", "25/09/2016", "21/09/2018"];
//Iterate array
dates.forEach(
function(date){
console.log(date + " matches with regex?");
console.log(regex.test(date));
});
_x000D_
Of course you can use as boolean:
if(regex.test(date)){
//do something
}
$("#theDiv").append("<img id='theImg' src='theImg.png'/>");
You need to read the documentation here.
My problem was that I've had two paths on my PC that contained the same libraries. Both paths were added to the Additional Library Directories in Configuration Properties -> Linker -> General. Removing one of the paths solved the problem.
require_relative
is a convenient subset of require
require_relative('path')
equals:
require(File.expand_path('path', File.dirname(__FILE__)))
if __FILE__
is defined, or it raises LoadError
otherwise.
This implies that:
require_relative 'a'
and require_relative './a'
require relative to the current file (__FILE__
).
This is what you want to use when requiring inside your library, since you don't want the result to depend on the current directory of the caller.
eval('require_relative("a.rb")')
raises LoadError
because __FILE__
is not defined inside eval
.
This is why you can't use require_relative
in RSpec tests, which get eval
ed.
The following operations are only possible with require
:
require './a.rb'
requires relative to the current directory
require 'a.rb'
uses the search path ($LOAD_PATH
) to require. It does not find files relative to current directory or path.
This is not possible with require_relative
because the docs say that path search only happens when "the filename does not resolve to an absolute path" (i.e. starts with /
or ./
or ../
), which is always the case for File.expand_path
.
The following operation is possible with both, but you will want to use require
as it is shorter and more efficient:
require '/a.rb'
and require_relative '/a.rb'
both require the absolute path.Reading the source
When the docs are not clear, I recommend that you take a look at the sources (toggle source in the docs). In some cases, it helps to understand what is going on.
require:
VALUE rb_f_require(VALUE obj, VALUE fname) {
return rb_require_safe(fname, rb_safe_level());
}
require_relative:
VALUE rb_f_require_relative(VALUE obj, VALUE fname) {
VALUE base = rb_current_realfilepath();
if (NIL_P(base)) {
rb_loaderror("cannot infer basepath");
}
base = rb_file_dirname(base);
return rb_require_safe(rb_file_absolute_path(fname, base), rb_safe_level());
}
This allows us to conclude that
require_relative('path')
is the same as:
require(File.expand_path('path', File.dirname(__FILE__)))
because:
rb_file_absolute_path =~ File.expand_path
rb_file_dirname1 =~ File.dirname
rb_current_realfilepath =~ __FILE__
In my case (Mac OS Mojave), the key is to use the full path
$umount -f /Volumnes/fullpath/folder
public static int [] locations={1,2,3};
public static test dot=new test();
Declare the above variables above the main method and the code compiles fine.
public static void main(String[] args){
There is a convenient third party tool named FileMenu Tools, that gives several right-click tools as a windows explorer extension.
One of them is Split file / Join Parts, that does and undoes exactly what you are looking for.
Check it at http://www.lopesoft.com/en/filemenutools. Of course, it is windows only, as Unixes environments already have lots of tools for that.
Conceptually there are the two "domains" classes and interfaces. Inside these domains you are always extending, only a class implements an interface, which is kind of "crossing the border". So basically "extends" for interfaces mirrors the behavior for classes. At least I think this is the logic behind. It seems than not everybody agrees with this kind of logic (I find it a little bit contrived myself), and in fact there is no technical reason to have two different keywords at all.
Edit: I have just explained logic to pair here. If anybody want to go with the complete code then see my another answer. I have answered here for logic only but I was not able to explain properly, So I have added another answer in the same thread.
Try this to do pairing:
If you are able to search the devices then this would be your next step
ArrayList<BluetoothDevice> arrayListBluetoothDevices = NEW ArrayList<BluetoothDevice>;
I am assuming that you have the list of Bluetooth devices added in the arrayListBluetoothDevices
:
BluetoothDevice bdDevice;
bdDevice = arrayListBluetoothDevices.get(PASS_THE_POSITION_TO_GET_THE_BLUETOOTH_DEVICE);
Boolean isBonded = false;
try {
isBonded = createBond(bdDevice);
if(isBonded)
{
Log.i("Log","Paired");
}
} catch (Exception e)
{
e.printStackTrace();
}
The createBond()
method:
public boolean createBond(BluetoothDevice btDevice)
throws Exception
{
Class class1 = Class.forName("android.bluetooth.BluetoothDevice");
Method createBondMethod = class1.getMethod("createBond");
Boolean returnValue = (Boolean) createBondMethod.invoke(btDevice);
return returnValue.booleanValue();
}
Add this line into your Receiver in the ACTION_FOUND
if (device.getBondState() != BluetoothDevice.BOND_BONDED) {
mNewDevicesArrayAdapter.add(device.getName() + "\n" + device.getAddress());
arrayListBluetoothDevices.add(device);
}
In your app config -
$httpProvider.defaults.transformRequest = function (data) {
if (data === undefined)
return data;
var clonedData = $.extend(true, {}, data);
for (var property in clonedData)
if (property.substr(0, 1) == '$')
delete clonedData[property];
return $.param(clonedData);
};
With your resource request -
headers: {
'Content-Type': 'application/x-www-form-urlencoded'
}
The urls are different.
http://localhost/AccountSvc/DataInquiry.asmx
vs.
/acctinqsvc/portfolioinquiry.asmx
Resolve this issue first, as if the web server cannot resolve the URL you are attempting to POST to, you won't even begin to process the actions described by your request.
You should only need to create the WebRequest to the ASMX root URL, ie: http://localhost/AccountSvc/DataInquiry.asmx
, and specify the desired method/operation in the SOAPAction header.
The SOAPAction header values are different.
http://localhost/AccountSvc/DataInquiry.asmx/ + methodName
vs.
http://tempuri.org/GetMyName
You should be able to determine the correct SOAPAction by going to the correct ASMX URL and appending ?wsdl
There should be a <soap:operation>
tag underneath the <wsdl:operation>
tag that matches the operation you are attempting to execute, which appears to be GetMyName
.
There is no XML declaration in the request body that includes your SOAP XML.
You specify text/xml
in the ContentType of your HttpRequest and no charset. Perhaps these default to us-ascii
, but there's no telling if you aren't specifying them!
The SoapUI created XML includes an XML declaration that specifies an encoding of utf-8, which also matches the Content-Type provided to the HTTP request which is: text/xml; charset=utf-8
Hope that helps!
In my case, the root cause of this exception comes from using an old version mysql-connector and I had this error :
unable to load authentication plugin 'caching_sha2_password'. mysql
Adding this line to the mysql server configuration file (my.cnf or my.ini) fix this issue :
default_authentication_plugin=mysql_native_password
Is the result of getElementsByClassName an Array?
No
If not, what is it?
As with all DOM methods that return multiple elements, it is a NodeList, see https://developer.mozilla.org/en/DOM/document.getElementsByClassName

As apps run in the background anyway. I’m assuming what your really asking is how do you make apps do stuff in the background. The solution below will make your app do stuff in the background after opening the app and after the system has rebooted.
Below, I’ve added a link to a fully working example (in the form of an Android Studio Project)
This subject seems to be out of the scope of the Android docs, and there doesn’t seem to be any one comprehensive doc on this. The information is spread across a few docs.
The following docs tell you indirectly how to do this: https://developer.android.com/reference/android/app/Service.html
https://developer.android.com/reference/android/content/BroadcastReceiver.html
https://developer.android.com/guide/components/bound-services.html
In the interests of getting your usage requirements correct, the important part of this above doc to read carefully is: #Binder, #Messenger and the components link below:
https://developer.android.com/guide/components/aidl.html
Here is the link to a fully working example (in Android Studio format): http://developersfound.com/BackgroundServiceDemo.zip
This project will start an Activity which binds to a service; implementing the AIDL.
This project is also useful to re-factor for the purpose of IPC across different apps.
This project is also developed to start automatically when Android restarts (provided the app has been run at least one after installation and app is not installed on SD card)
When this app/project runs after reboot, it dynamically uses a transparent view to make it look like no app has started but the service of the associated app starts cleanly.
This code is written in such a way that it’s very easy to tweak to simulate a scheduled service.
This project is developed in accordance to the above docs and is subsequently a clean solution.
There is however a part of this project which is not clean being: I have not found a way to start a service on reboot without using an Activity. If any of you guys reading this post have a clean way to do this please post a comment.
For a Windows console app, you want to use SetConsoleCtrlHandler to handle CTRL+C and CTRL+BREAK.
See here for an example.
The simple way to use XMLHttpRequest
with pure JavaScript
. You can set custom header
but it's optional used based on requirement.
window.onload = function(){
var request = new XMLHttpRequest();
var params = "UID=CORS&name=CORS";
request.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200) {
console.log(this.responseText);
}
};
request.open('POST', 'https://www.example.com/api/createUser', true);
request.setRequestHeader('api-key', 'your-api-key');
request.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
request.send(params);
}
You can send params using POST method.
Please run below example and will get an JSON response.
window.onload = function(){_x000D_
var request = new XMLHttpRequest();_x000D_
_x000D_
request.onreadystatechange = function() {_x000D_
if (this.readyState == 4 && this.status == 200) {_x000D_
console.log(this.responseText);_x000D_
}_x000D_
};_x000D_
_x000D_
request.open('GET', 'https://jsonplaceholder.typicode.com/users/1');_x000D_
request.send();_x000D_
}

The full paramiko distribution ships with a lot of good demos.
In the demos subdirectory, demo.py
and interactive.py
have full interactive TTY examples which would probably be overkill for your situation.
In your example above ssh_stdin
acts like a standard Python file object, so ssh_stdin.write
should work so long as the channel is still open.
I've never needed to write to stdin, but the docs suggest that a channel is closed as soon as a command exits, so using the standard stdin.write
method to send a password up probably won't work. There are lower level paramiko commands on the channel itself that give you more control - see how the SSHClient.exec_command
method is implemented for all the gory details.
I think I see your problem, you need to use the @
syntax to define parameters you will pass in this way, also I'm not sure what loginID or password are doing you don't seem to define them anywhere and they are not being used as URL parameters so are they being sent as query parameters?
This is what I can suggest based on what I see so far:
.factory('MagComments', function ($resource) {
return $resource('http://localhost/dooleystand/ci/api/magCommenct/:id', {
loginID : organEntity,
password : organCommpassword,
id : '@magId'
});
})
The @magId
string will tell the resource to replace :id
with the property magId
on the object you pass it as parameters.
I'd suggest reading over the documentation here (I know it's a bit opaque) very carefully and looking at the examples towards the end, this should help a lot.
foreach ($arr ?: [] as $elem) {
// Do something
}
This doesen't check if it is an array, but skips the loop if the variable is null or an empty array.
It is worth noting that @Marius's second answer could be used as pure Javascript solution.
document.getElementById('elementId').tagName
Open a PL/SQL object in the Editor.
Click on the main toolbar or select Session | Toggle Compiling with Debug. This enables debugging.
Compile the object on the database.
Select one of the following options on the Execute toolbar to begin debugging: Execute PL/SQL with debugger () Step over Step into Run to cursor
I would avoid to do a query for each entry.
if(is_array($EMailArr)){
$sql = "INSERT INTO email_list (R_ID, EMAIL, NAME) values ";
$valuesArr = array();
foreach($EMailArr as $row){
$R_ID = (int) $row['R_ID'];
$email = mysql_real_escape_string( $row['email'] );
$name = mysql_real_escape_string( $row['name'] );
$valuesArr[] = "('$R_ID', '$email', '$name')";
}
$sql .= implode(',', $valuesArr);
mysql_query($sql) or exit(mysql_error());
}
If you have a SSHClient, you can also use open_sftp()
:
import paramiko
# lets say you have SSH client...
client = paramiko.SSHClient()
sftp = client.open_sftp()
# then you can use upload & download as shown above
...
I am from Angular as well and trying out React, as of now, one recommended(?) way seems to be using High-Order Components:
A higher-order component (HOC) is an advanced technique in React for reusing component logic. HOCs are not part of the React API, per se. They are a pattern that emerges from React’s compositional nature.
Let's say you have input
and textarea
and like to apply the same validation logic:
const Input = (props) => (
<input type="text"
style={props.style}
onChange={props.onChange} />
)
const TextArea = (props) => (
<textarea rows="3"
style={props.style}
onChange={props.onChange} >
</textarea>
)
Then write a HOC that does validate and style wrapped component:
function withValidator(WrappedComponent) {
return class extends React.Component {
constructor(props) {
super(props)
this.validateAndStyle = this.validateAndStyle.bind(this)
this.state = {
style: {}
}
}
validateAndStyle(e) {
const value = e.target.value
const valid = value && value.length > 3 // shared logic here
const style = valid ? {} : { border: '2px solid red' }
console.log(value, valid)
this.setState({
style: style
})
}
render() {
return <WrappedComponent
onChange={this.validateAndStyle}
style={this.state.style}
{...this.props} />
}
}
}
Now those HOCs share the same validating behavior:
const InputWithValidator = withValidator(Input)
const TextAreaWithValidator = withValidator(TextArea)
render((
<div>
<InputWithValidator />
<TextAreaWithValidator />
</div>
), document.getElementById('root'));
I created a simple demo.
Edit: Another demo is using props to pass an array of functions so that you can share logic composed by multiple validating functions across HOC
s like:
<InputWithValidator validators={[validator1,validator2]} />
<TextAreaWithValidator validators={[validator1,validator2]} />
Edit2: React 16.8+ provides a new feature, Hook, another nice way to share logic.
const Input = (props) => {
const inputValidation = useInputValidation()
return (
<input type="text"
{...inputValidation} />
)
}
function useInputValidation() {
const [value, setValue] = useState('')
const [style, setStyle] = useState({})
function handleChange(e) {
const value = e.target.value
setValue(value)
const valid = value && value.length > 3 // shared logic here
const style = valid ? {} : { border: '2px solid red' }
console.log(value, valid)
setStyle(style)
}
return {
value,
style,
onChange: handleChange
}
}

Commit frequency depends on your style of project management. Many people refrain from committing if it'll break the build (or functionality).
Branches can be used in one of two ways, typically: 1) One active branch for development (and the trunk stays stable), or 2) branches for alternate dev paths.
Tags are generally used for identifying releases, so they don't get lost in the mix. The definition of 'release' is up to you.
var lastname = "Hi";
if(typeof lastname !== "undefined")
{
alert("Hi. Variable is defined.");
}
It sounds like you haven't added the right directory to your path.
First find out which directory you've installed Java in. For example, on my box it's in C:\Program Files\java\jdk1.7.0_11
1. Once you've found it, try running it directly. For example:
c:\> "c:\Program Files\java\jdk1.7.0_11\bin\java" -version
Once you've definitely got the right version, add the bin
directory to your PATH
environment variable.
Note that you don't need a JAVA_HOME
environment variable, and haven't for some time. Some tools may use it - and if you're using one of those, then sure, set it - but if you're just using (say) Eclipse and the command-line java
/javac
tools, you're fine without it.
1 Yes, this has reminded me that I need to update...
time1
is the key of the most outer dictionary, eg, feb2012
. So then you're trying to index the string, but you can only do this with integers. I think what you wanted was:
for info in courses[time1][course]:
As you're going through each dictionary, you must add another nest.
Using:
SELECT t.ctn_no
FROM YOUR_TABLE t
GROUP BY t.ctn_no
HAVING COUNT(t.ctn_no) > 1
...will show you the ctn_no
value(s) that have duplicates in your table. Adding criteria to the WHERE will allow you to further tune what duplicates there are:
SELECT t.ctn_no
FROM YOUR_TABLE t
WHERE t.s_ind = 'Y'
GROUP BY t.ctn_no
HAVING COUNT(t.ctn_no) > 1
If you want to see the other column values associated with the duplicate, you'll want to use a self join:
SELECT x.*
FROM YOUR_TABLE x
JOIN (SELECT t.ctn_no
FROM YOUR_TABLE t
GROUP BY t.ctn_no
HAVING COUNT(t.ctn_no) > 1) y ON y.ctn_no = x.ctn_no
Calling
for /?
in the command-line gives help about this syntax (which can be used outside FOR, too, this is just the place where help can be found).
In addition, substitution of FOR variable references has been enhanced. You can now use the following optional syntax:
%~I - expands %I removing any surrounding quotes (") %~fI - expands %I to a fully qualified path name %~dI - expands %I to a drive letter only %~pI - expands %I to a path only %~nI - expands %I to a file name only %~xI - expands %I to a file extension only %~sI - expanded path contains short names only %~aI - expands %I to file attributes of file %~tI - expands %I to date/time of file %~zI - expands %I to size of file %~$PATH:I - searches the directories listed in the PATH environment variable and expands %I to the fully qualified name of the first one found. If the environment variable name is not defined or the file is not found by the search, then this modifier expands to the empty string
The modifiers can be combined to get compound results:
%~dpI - expands %I to a drive letter and path only %~nxI - expands %I to a file name and extension only %~fsI - expands %I to a full path name with short names only %~dp$PATH:I - searches the directories listed in the PATH environment variable for %I and expands to the drive letter and path of the first one found. %~ftzaI - expands %I to a DIR like output line
In the above examples %I and PATH can be replaced by other valid values. The %~ syntax is terminated by a valid FOR variable name. Picking upper case variable names like %I makes it more readable and avoids confusion with the modifiers, which are not case sensitive.
There are different letters you can use like f
for "full path name", d
for drive letter, p
for path, and they can be combined. %~
is the beginning for each of those sequences and a number I
denotes it works on the parameter %I
(where %0
is the complete name of the batch file, just like you assumed).

This works for me:
adb shell dumpsys activity
And this to show current activity name:
adb shell dumpsys activity activities | grep mFocusedActivity | cut -d . -f 5 | cut -d ' ' -f 1
HTML4/XHTML1 requires
<script type="...">...</script>
HTML5 faces the fact that there is only one scripting language on the web, and allows
<script>...</script>
The latter works in any browser that supports scripting (NN2+).

We can use title()
function with negative line
value to bring down the title.
See this example:
plot(1, 1)
title("Title", line = -2)
Use css:
<style>
input[name=btnsubmit]:active {
color: green;
}
</style>
I ran into a similar problem and just passed the end of the array to the ArrayList.add()
index param like so:
public class Stack {
private ArrayList<String> stringList = new ArrayList<String>();
RandomStringGenerator rsg = new RandomStringGenerator();
private void push(){
String random = rsg.randomStringGenerator();
stringList.add(stringList.size(), random);
}
}
Let's face it: php does NOT have a simple out of the box function to properly handle every array sort scenario.
This routine is intuitive, which means faster debugging and maintenance:
// automatic population of array
$tempArray = array();
$annotations = array();
// ... some code
// SQL $sql retrieves result array $result
// $row[0] is the ID, but is populated out of order (comes from
// multiple selects populating various dimensions for the same DATE
// for example
while($row = mysql_fetch_array($result)) {
$needle = $row[0];
arrayIndexes($needle); // create a parallel array with IDs only
$annotations[$needle]['someDimension'] = $row[1]; // whatever
}
asort($tempArray);
foreach ($tempArray as $arrayKey) {
$dataInOrder = $annotations[$arrayKey]['someDimension'];
// .... more code
}
function arrayIndexes ($needle) {
global $tempArray;
if (!in_array($needle,$tempArray)) {
array_push($tempArray,$needle);
}
}
You're looking for the cunningly named Registry.GetValue
method.
If anyone is using GoDaddy Shared Hosting, you can try for following solution, worked for me.
When starting DB connection, set the time_zone command in my PDO object e.g.:
$pdo = new PDO($dsn, $user, $pass, $opt);
$pdo->exec("SET time_zone='+05:30';");
Where "+05:30" is the TimeZone of India. You can change it as per your need.
After that; all the MySQL processes related to Date and Time are set with required timezone.

If you haven't installed matplotlib yet just try the command.
> pip install matplotlib
import matplotlib.pyplot as plot
plot.hist(weightList,density=1, bins=20)
plot.axis([50, 110, 0, 0.06])
#axis([xmin,xmax,ymin,ymax])
plot.xlabel('Weight')
plot.ylabel('Probability')
plot.show()
I searched for a similar issue,
Wanted to throw away local commits:
So did the below:
git reset --hard origin/dev
Check:
git status
On branch dev
Your branch is up-to-date with 'origin/dev'.
nothing to commit, working tree clean
now local commits are lost, back to the initial cloned state, point 1 above.
You need to write it like sprintf(aa, "%9.7lf", a)
Check out http://en.wikipedia.org/wiki/Printf for some more details on format codes.
This should be faster.
while ($personCount < 10) {
$result .= "{$personCount} people ";
$personCount++;
}
echo $result;
If you can use a third party utility, here is an elevate
command line utility.
This is the usage description:
Usage: Elevate [-?|-wait|-k] prog [args]
-? - Shows this help
-wait - Waits until prog terminates
-k - Starts the the %COMSPEC% environment variable value and
executes prog in it (CMD.EXE, 4NT.EXE, etc.)
prog - The program to execute
args - Optional command line arguments to prog

Check VBA-JSON-parser on GitHub for the latest version and examples. Import JSON.bas module into the VBA project for JSON processing.
UPDATE 2 (Oct 1 '16)
However if you do want to parse JSON on 64-bit Office with ScriptControl
, then this answer may help you to get ScriptControl
to work on 64-bit.
UPDATE (Oct 26 '15)
Note that a ScriptControl
-based approachs makes the system vulnerable in some cases, since they allows a direct access to the drives (and other stuff) for the malicious JS code via ActiveX's. Let's suppose you are parsing web server response JSON, like JsonString = "{a:(function(){(new ActiveXObject('Scripting.FileSystemObject')).CreateTextFile('C:\\Test.txt')})()}"
. After evaluating it you'll find new created file C:\Test.txt
. So JSON parsing with ScriptControl
ActiveX is not a good idea.
Trying to avoid that, I've created JSON parser based on RegEx's. Objects {}
are represented by dictionaries, that makes possible to use dictionary's properties and methods: .Count
, .Exists()
, .Item()
, .Items
, .Keys
. Arrays []
are the conventional zero-based VB arrays, so UBound()
shows the number of elements. Here is the code with some usage examples:
Option Explicit
Sub JsonTest()
Dim strJsonString As String
Dim varJson As Variant
Dim strState As String
Dim varItem As Variant
' parse JSON string to object
' root element can be the object {} or the array []
strJsonString = "{""a"":[{}, 0, ""value"", [{""stuff"":""content""}]], b:null}"
ParseJson strJsonString, varJson, strState
' checking the structure step by step
Select Case False ' if any of the checks is False, the sequence is interrupted
Case IsObject(varJson) ' if root JSON element is object {},
Case varJson.Exists("a") ' having property a,
Case IsArray(varJson("a")) ' which is array,
Case UBound(varJson("a")) >= 3 ' having not less than 4 elements,
Case IsArray(varJson("a")(3)) ' where forth element is array,
Case UBound(varJson("a")(3)) = 0 ' having the only element,
Case IsObject(varJson("a")(3)(0)) ' which is object,
Case varJson("a")(3)(0).Exists("stuff") ' having property stuff,
Case Else
MsgBox "Check the structure step by step" & vbCrLf & varJson("a")(3)(0)("stuff") ' then show the value of the last one property.
End Select
' direct access to the property if sure of structure
MsgBox "Direct access to the property" & vbCrLf & varJson.Item("a")(3)(0).Item("stuff") ' content
' traversing each element in array
For Each varItem In varJson("a")
' show the structure of the element
MsgBox "The structure of the element:" & vbCrLf & BeautifyJson(varItem)
Next
' show the full structure starting from root element
MsgBox "The full structure starting from root element:" & vbCrLf & BeautifyJson(varJson)

One more opportunity of this JSON RegEx parser is that it works on 64-bit Office, where ScriptControl isn't available.

ActiveX, without external libraries:
Sub JsonTest()

' Dictionaries have numeric keys for JSON Arrays, and string keys for JSON Objects
' Returns Nothing in case of any JSON syntax issues
Set Dict = GetJsonDict("{a:[[{stuff:'result'}]], b:''}")
' You can use For Each ... Next and For ... Next loops through keys and items
Keys = Dict.Keys
Items = Dict.Items
' Referring directly to the necessary property if sure, without any checks
MsgBox Dict("a")(0)(0)("stuff")
' Auxiliary DrillDown() function
' Drilling down the structure, sequentially checking if each level exists
Select Case False
Case DrillDown(Dict, "a", Temp, "")
Case DrillDown(Temp, 0, Temp, "")
Case DrillDown(Temp, 0, Temp, "")
Case DrillDown(Temp, "stuff", "", Text)
Case Else
' Structure is consistent, requested value found

End Select
End Sub

TLS 1.2
is only supported since OpenSSL 1.0.1
(see the Major version releases section), you have to update your OpenSSL
.
It is not necessary to set the CURLOPT_SSLVERSION
option. The request involves a handshake which will apply the newest TLS
version both server and client support. The server you request is using TLS 1.2
, so your php_curl
will use TLS 1.2
(by default) as well if your OpenSSL
version is (or newer than) 1.0.1
.
I'm start to create own Perl script based on SQL::Translator module (GraphViz). Here are first results.
You can set the SelectedValue
to the value you want to select. If you already have selected item then you should clear the selection otherwise you would get "Cannot have multiple items selected in a DropDownList" error.
dropdownlist.ClearSelection();
dropdownlist.SelectedValue = value;
You can also use ListItemCollection.FindByText or ListItemCollection.FindByValue
dropdownlist.ClearSelection();
dropdownlist.Items.FindByValue(value).Selected = true;
Use the FindByValue method to search the collection for a ListItem with a Value property that contains value specified by the value parameter. This method performs a case-sensitive and culture-insensitive comparison. This method does not do partial searches or wildcard searches. If an item is not found in the collection using this criteria, null is returned, MSDN.
If you expect that you may be looking for text/value that wont be present in DropDownList
ListItem collection then you must check if you get the ListItem
object or null
from FindByText
or FindByValue
before you access Selected property. If you try to access Selected when null is returned then you will get NullReferenceException.
ListItem listItem = dropdownlist.Items.FindByValue(value);
if(listItem != null)
{
dropdownlist.ClearSelection();
listItem.Selected = true;
}
bootstrap 3 has a class to align the text within a div
<div class="text-right">
will align the text on the right
<div class="pull-right">
will pull to the right all the content not only the text
The other answers lack a concrete example, so here it goes:
Given the following People table:
FirstName | LastName | YearOfBirth
----------------------------------------
Thomas | Alva Edison | 1847
Benjamin | Franklin | 1706
Thomas | More | 1478
Thomas | Jefferson | 1826
If you execute the query below:
SELECT * FROM People ORDER BY FirstName DESC, YearOfBirth ASC
The result set will look like this:
FirstName | LastName | YearOfBirth
----------------------------------------
Thomas | More | 1478
Thomas | Jefferson | 1826
Thomas | Alva Edison | 1847
Benjamin | Franklin | 1706

Since there is only one WiFi hardware on the computer its not possible to connect one WiFi hardware to multiple WiFi networks, if you want to that I think you have to map WiFi hardware to guest OS and how host you'll have to use some other hardware (may be Ethernet) but I'm sure that it will work in that way as no VM software allow us to allocate Hardware to Guest except for USB, you can also get USB WiFI and allocate that to VM only.

Different types of variable:
DECLARE is permitted only inside a BEGIN ... END compound statement and must be at its start, before any other statements.
Therefore, if you are defining a stored program and actually do want a "local variable", you will need to drop the @ character and ensure that your DECLARE statement is at the start of your program block. Otherwise, to use a "user variable", drop the DECLARE statement.
Furthermore, you will either need to surround your query in parentheses in order to execute it as a subquery:
SET @countTotal = (SELECT COUNT(*) FROM nGrams);
Or else, you could use SELECT ... INTO:
SELECT COUNT(*) INTO @countTotal FROM nGrams;
Session["YourItem"] = "";

So if you want to programmatically copy google-services.json
file from all your variants into your root folder. When you switch to a specific variant here's a solution for you
android {
applicationVariants.all { variant ->
copy {
println "Switches to $variant google-services.json"
from "src/$variant"
include "google-services.json"
into "."
}
}
}
There's a caveat to this approach that is you need to have google-service.json
file in each of your variants folder here's an example.
In RStudio, to increase:
file.edit(file.path("~", ".Rprofile"))
then in .Rprofile type this and save
invisible(utils::memory.limit(size = 60000))
To decrease: open .Rprofile
invisible(utils::memory.limit(size = 30000))
save and restart RStudio.
All the info you need, is provided in the release announcement for m2e 1.1:
m2e 1.1 has been released as part of Eclipse Juno simultaneous release today.
[...]
m2e 1.1 is already included in "Eclipse IDE for Java Developers" package available from http://eclipse.org/downloads/ or it can be installed from Eclipse Juno release repository [2]. Eclipse 3.7/Indigo users can install the new version from m2e release repository [3]
[...]
In Mac, for me this works:

You can also try this if you want to occur for all the queries:
var sequelize = new Sequelize('database', 'username', 'password', {query:{raw:true}})
you are using onclick
which is javascript event.
there is two ways
Javascript
<input type="button" value="Home" class="homebutton" id="btnHome"
onClick="window.location = 'http://google.com'" />
Or PHP
create another page as redirect.php and put
<?php header('location : google.com') ?>
and insert this link on any page within the same directory
<a href="redirect.php">google<a/>
hope this helps its simplest!!
- Here its more about the coding style
than being the functionality....
- The 1st option is very clear, but then the 2nd one is quite elegant... no offense, its just my view..
You could do below:

iif ( OpeningBalance>=5001 And OpeningBalance<=10000 , 30,
iif ( OpeningBalance>=10001 And OpeningBalance<=20000 , 40,
50 ) ) ) as commission

You cannot set or read cookies on CORS requests through JavaScript. Although CORS allows cross-origin requests, the cookies are still subject to the browser's same-origin policy, which means only pages from the same origin can read/write the cookie. withCredentials
only means that any cookies set by the remote host are sent to that remote host. You will have to set the cookie from the remote server by using the Set-Cookie
header.
It's useful to remember that state machines are an abstraction, and you don't need particular tools to create one, however tools can be useful.
You can for example realise a state machine with functions:
void Hunt(IList<Gull> gulls)
{
if (gulls.Empty())
return;
var target = gulls.First();
TargetAcquired(target, gulls);
}
void TargetAcquired(Gull target, IList<Gull> gulls)
{
var balloon = new WaterBalloon(weightKg: 20);
this.Cannon.Fire(balloon);
if (balloon.Hit)
{
TargetHit(target, gulls);
}
else
TargetMissed(target, gulls);
}
void TargetHit(Gull target, IList<Gull> gulls)
{
Console.WriteLine("Suck on it {0}!", target.Name);
Hunt(gulls);
}
void TargetMissed(Gull target, IList<Gull> gulls)
{
Console.WriteLine("I'll get ya!");
TargetAcquired(target, gulls);
}
This machine would hunt for gulls and try to hit them with water balloons. If it misses it will try firing one until it hits (could do with some realistic expectations ;)), otherwise it will gloat in the console. It continues to hunt until it's out of gulls to harass.
Each function corresponds to each state; the start and end (or accept) states are not shown. There are probably more states in there than modelled by the functions though. For example after firing the balloon the machine is really in another state than it was before it, but I decided this distinction was impractical to make.
A common way is to use classes to represent states, and then connect them in different ways.
According to JavaDocs, you can do this:
WebElement input = divA.findElement(By.xpath(".//input"));
How can I ask in xpath for "the div-tag that contains a span with the text 'hello world'"?
WebElement elem = driver.findElement(By.xpath("//div[span[text()='hello world']]"));
The XPath spec is a suprisingly good read on this.
Using ls:
ls -LR
from 'man ls':
-L, --dereference
when showing file information for a symbolic link, show informa-
tion for the file the link references rather than for the link
itself
Or, using find:
find -L .
From the find manpage:
-L Follow symbolic links.
If you find you want to only follow a few symbolic links (like maybe just the toplevel ones you mentioned), you should look at the -H option, which only follows symlinks that you pass to it on the commandline.
Just think of what the words "child" and "descendant" mean in English:
byte[] fileData = null;
using (var binaryReader = new BinaryReader(Request.Files[0].InputStream))
{
fileData = binaryReader.ReadBytes(Request.Files[0].ContentLength);
}
You could use CSS to do that, but it wouldn't be supported in IE8-. You can use some site like http://borderradius.com to come up with actual CSS you'd use, which would look something like this (again, depending on how many browsers you're trying to support):
-webkit-border-radius: 5px;
-moz-border-radius: 5px;
border-radius: 5px;
Personally, I almost never have the need to write abstract classes.
Most times I see abstract classes being (mis)used, it's because the author of the abstract class is using the "Template method" pattern.
The problem with "Template method" is that it's nearly always somewhat re-entrant - the "derived" class knows about not just the "abstract" method of its base class that it is implementing, but also about the public methods of the base class, even though most times it does not need to call them.
(Overly simplified) example:
abstract class QuickSorter
{
public void Sort(object[] items)
{
// implementation code that somewhere along the way calls:
bool less = compare(x,y);
// ... more implementation code
}
abstract bool compare(object lhs, object rhs);
}
So here, the author of this class has written a generic algorithm and intends for people to use it by "specializing" it by providing their own "hooks" - in this case, a "compare" method.
So the intended usage is something like this:
class NameSorter : QuickSorter
{
public bool compare(object lhs, object rhs)
{
// etc.
}
}
The problem with this is that you've unduly coupled together two concepts:
In the above code, theoretically, the author of the "compare" method can re-entrantly call back into the superclass "Sort" method... even though in practise they will never want or need to do this.
The price you pay for this unneeded coupling is that it's hard to change the superclass, and in most OO languages, impossible to change it at runtime.
The alternative method is to use the "Strategy" design pattern instead:
interface IComparator
{
bool compare(object lhs, object rhs);
}
class QuickSorter
{
private readonly IComparator comparator;
public QuickSorter(IComparator comparator)
{
this.comparator = comparator;
}
public void Sort(object[] items)
{
// usual code but call comparator.Compare();
}
}
class NameComparator : IComparator
{
bool compare(object lhs, object rhs)
{
// same code as before;
}
}
So notice now: All we have are interfaces, and concrete implementations of those interfaces. In practise, you don't really need anything else to do a high level OO design.
To "hide" the fact that we've implemented "sorting of names" by using a "QuickSort" class and a "NameComparator", we might still write a factory method somewhere:
ISorter CreateNameSorter()
{
return new QuickSorter(new NameComparator());
}
Any time you have an abstract class you can do this... even when there is a natural re-entrant relationship between the base and derived class, it usually pays to make them explicit.
One final thought: All we've done above is "compose" a "NameSorting" function by using a "QuickSort" function and a "NameComparison" function... in a functional programming language, this style of programming becomes even more natural, with less code.
As for 2018 there is still not a simple answer to the question of how to convert a PDF document to an image in C#; many libraries use Ghostscript licensed under AGPL and in most cases an expensive commercial license is required for production use.
A good alternative might be using the popular 'pdftoppm' utility which has a GPL license; it can be used from C# as command line tool executed with System.Diagnostics.Process. Popular tools are well known in the Linux world, but a windows build is also available.
If you don't want to integrate pdftoppm by yourself, you can use my PdfRenderer popular wrapper (supports both classic .NET Framework and .NET Core) - it is not free, but pricing is very affordable.
Consider the following for-comprehension
val A = for (i <- Int.MinValue to Int.MaxValue; if i > 3) yield i
It may be helpful to read it out loud as follows
"For each integer i
, if it is greater than 3
, then yield (produce) i
and add it to the list A
."
In terms of mathematical set-builder notation, the above for-comprehension is analogous to
which may be read as
"For each integer , if it is greater than , then it is a member of the set ."
or alternatively as
" is the set of all integers , such that each is greater than ."
For users using XAMPP, there are 2 max_allowed_packet parameters in C:\xampp\mysql\bin\my.ini.
If you want to use the BrowsableAttribute, then you can look for it at runtime on the model and hide the column accordingly:
private void Form_Load(object sender, EventArgs e)
{
//add this line after your DataGridView initialization
HideColumns<MyModel>(myDvg);
}
private void HideColumns<T>(DataGridView dvg)
{
var type = typeof(T);
foreach (var column in dvg.Columns.Cast<DataGridViewColumn>())
column.Visible = IsBrowsable(type.GetProperty(column.Name));
}
private bool IsBrowsable(PropertyInfo propertyInfo)
{
var attribute = propertyInfo.GetCustomAttributes(true).FirstOrDefault(att => att.GetType() == typeof(BrowsableAttribute));
return attribute == null || (attribute as BrowsableAttribute).Browsable;
}
This is from MSDN sample:
(*.bmp, *.jpg)|*.bmp;*.jpg
So for your case
openFileDialog1.Filter = "JPG (*.jpg,*.jpeg)|*.jpg;*.jpeg|TIFF (*.tif,*.tiff)|*.tif;*.tiff"
Use the Array#join
method (the argument to join
is what to insert between the strings - in this case a space):
@arr.join(" ")

Others have answered your earlier question. For this:
As an addendum, is there any way to extract directly with the header names rather than with column numbers?
I haven't tried it, but you could store each header's index in a hash and then use that hash to get its index later on.
for(i=0;i<$NF;i++){
hash[$i] = i;
}
Then later on, use it:
j = hash["header1"];
print $j;
I use the following method in my project

int size = sizeof(codes)/sizeof(int);
NSMutableArray *array = [[NSMutableArray alloc] init];
for (int i=0;i<size;++i){
[array addObject:[NSNumber numberWithInt:codes[i]]];
}
codesArray = [array copy];
}
}
return codesArray;
}
Then I just check the error code and show alert if it is in the list
if ([[self networkErrorCodes] containsObject:[NSNumber
numberWithInt:[error code]]]){
// Fire Alert View Here
}
But as you can see I commented out codes that I think does not fit to my definition of NO INTERNET. E.g the code of -1012 (Authentication fail.) You may edit the list as you like.
In my project I use it at username/password entering from user. And in my view (physical) network connection errors could be the only reason to show alert view in your network based app. In any other case (e.g. incorrect username/password pair) I prefer to do some custom user friendly animation, OR just repeat the failed attempt again without any attention of the user. Especially if the user didn't explicitly initiated a network call.

One idea would be to winsorize the data in a two-pass procedure:
run a first pass, learn what the bounds are, e.g. cut of at given percentile, or N standard deviation above the mean, or ...
in a second pass, set the values beyond the given bound to the value of that bound
I should stress that this is an old-fashioned method which ought to be dominated by more modern robust techniques but you still come across it a lot.

Here is the short sweet answer using HtmlAgilityPack. You can run this in LinqPad.
var html = "<div>..whatever html</div>";
var doc = new HtmlAgilityPack.HtmlDocument();
doc.LoadHtml(html);
var plainText = doc.DocumentNode.InnerText;
I simply use HtmlAgilityPack in any .NET project that needs HTML parsing. It's simple, reliable, and fast.
I suggest such way based on extension methods:
IEnumerable<Int32> countryIDs =

.AsEnumerable()
.Where(row => row.Field<String>("CountryName") == countryName)
.Select(row => row.Field<Int32>("CountryID"));
System.Data.DataSetExtensions.dll needs to be referenced.

The 'X' only works if partial seconds are not present: i.e. SimpleDateFormat pattern of
"yyyy-MM-dd'T'HH:mm:ssX"
Will correctly parse
"2008-01-31T00:00:00Z"
but
"yyyy-MM-dd'T'HH:mm:ss.SX"
Will NOT parse
"2008-01-31T00:00:00.000Z"
Sad but true, a date-time with partial seconds does not appear to be a valid ISO date: http://en.wikipedia.org/wiki/ISO_8601
System read-only variable %CD%
keeps the path of the caller of the batch, not the batch file location.
You can get the name of the batch script itself as typed by the user with %0
(e.g. scripts\mybatch.bat
). Parameter extensions can be applied to this so %~dp0
will return the Drive and Path to the batch script (e.g. W:\scripts\
) and %~f0
will return the full pathname (e.g. W:\scripts\mybatch.cmd
).
You can refer to other files in the same folder as the batch script by using this syntax:
CALL %0\..\SecondBatch.cmd
This can even be used in a subroutine, Echo %0
will give the call label but, echo "%~nx0"
will give you the filename of the batch script.
When the %0
variable is expanded, the result is enclosed in quotation marks.
Check the settings.gradle
file. The modules which are included may be missing or in another directory. For instance, with below line in settings.gradle
, gradle searches common-lib
module inside your project directory:
include ':common-lib'
If it is missing, you can find and copy this module into your project or reference its path in settings.gradle
file:
include ':common-lib'
project(':common-lib').projectDir = new File('<path to your module i.e. C://Libraries/common-lib>') //
DateTime
is not standard nullable type. If you want assign null to DateTime
type of variable, you have to use DateTime?
type which supports null value.
If you only want test your variable to be set (e.g. variable holds other than default value), you can use keyword "default" like in following code:
if (dateTimeVariable == default(DateTime))
{
//do work for dateTimeVariable == null situation
}

Many outdated, over-complicated and weird answers here. The reason is that the documentation is inadequate and the simple solution is to just use basicConfig()
and set it as follows:
logging.basicConfig(datefmt='%Y-%m-%d %H:%M:%S', format='{asctime}.{msecs:0<3.0f} {name} {threadName} {levelname}: {message}', style='{')
The trick here was that you have to also set the datefmt
argument, as the default messes it up and is not what is (currently) shown in the how-to python docs. So rather look here.
An alternative and possibly cleaner way, would have been to override the default_msec_format
variable with:
formatter = logging.Formatter('%(asctime)s')
formatter.default_msec_format = '%s.%03d'
However, that did not work for unknown reasons.
PS. I am using Python 3.8.
Make sure that this element you would like to control with z-index does not have a parent with z-index property, because element is in a lower stacking context due to its parent’s z-index level.
Here's an example:
<section class="content">
<div class="modal"></div>

<div class="side-tab"></div>
// CSS //
.content {
position: relative;
z-index: 1;
}
.modal {
position: fixed;
z-index: 100;
}
.side-tab {
position: fixed;
z-index: 5;
}
In the example above, the modal has a higher z-index than the content, although the content will appear on top of the modal because "content" is the parent with a z-index property.
Here's an article that explains 4 reasons why z-index might not work: https://coder-coder.com/z-index-isnt-working/
Well, switch
probably wasn't really meant to work like this, but you can:
AA = 'foo'
switch(AA,
foo={
# case 'foo' here...
print('foo')
},
bar={
# case 'bar' here...
print('bar')
},
{
print('default')
}
)
...each case is an expression - usually just a simple thing, but here I use a curly-block so that you can stuff whatever code you want in there...
function showstuff(boxid){
document.getElementById(boxid).style.visibility="visible";
}
<button onclick="showstuff('id_to_show');" />
This will help you, I think.
Sometimes it doesnt fire when the script has some syntax error, make sure the script and javascript syntax is correct.
One thing I would add here is that the at
function on a dataframe is much faster particularly if you are doing a lot of assignments of individual (not slice) values.
df.at[index, 'col_name'] = x
In my experience I have gotten a 20x speedup. Here is a write up that is Spanish but still gives an impression of what's going on.
You need to write a selector which selects the correct <input>
first. Ideally you use the element's ID $('#element_id')
, failing that the ID of it's container $('#container_id input')
, or the element's class $('input.class_name')
.
Your element has none of these and no context, so it's hard to tell you how to select it.
Once you have figured out the proper selector, you'd use the attr method to access the element's attributes. To get the name, you'd use $(selector).attr('name')
which would return (in your example) 'xxxxx'
.

To speed things up, I would take advantage of the fact that you are not asked to find an arbitrary image/object, but specifically one with the Coca-Cola logo. This is significant because this logo is very distinctive, and it should have a characteristic, scale-invariant signature in the frequency domain, particularly in the red channel of RGB. That is to say, the alternating pattern of red-to-white-to-red encountered by a horizontal scan line (trained on a horizontally aligned logo) will have a distinctive "rhythm" as it passes through the central axis of the logo. That rhythm will "speed up" or "slow down" at different scales and orientations, but will remain proportionally equivalent. You could identify/define a few dozen such scanlines, both horizontally and vertically through the logo and several more diagonally, in a starburst pattern. Call these the "signature scan lines."
Searching for this signature in the target image is a simple matter of scanning the image in horizontal strips. Look for a high-frequency in the red-channel (indicating moving from a red region to a white one), and once found, see if it is followed by one of the frequency rhythms identified in the training session. Once a match is found, you will instantly know the scan-line's orientation and location in the logo (if you keep track of those things during training), so identifying the boundaries of the logo from there is trivial.
I would be surprised if this weren't a linearly-efficient algorithm, or nearly so. It obviously doesn't address your can-bottle discrimination, but at least you'll have your logos.
(Update: for bottle recognition I would look for coke (the brown liquid) adjacent to the logo -- that is, inside the bottle. Or, in the case of an empty bottle, I would look for a cap which will always have the same basic shape, size, and distance from the logo and will typically be all white or red. Search for a solid color eliptical shape where a cap should be, relative to the logo. Not foolproof of course, but your goal here should be to find the easy ones fast.)
(It's been a few years since my image processing days, so I kept this suggestion high-level and conceptual. I think it might slightly approximate how a human eye might operate -- or at least how my brain does!)
You can try to get the list of all elements with class = "content"
by using find_elements_by_class_name:
a = driver.find_elements_by_class_name("content")
Then you can click on the link that you are looking for.
It's not exactly double precision because of how IEEE 754 works, and because binary doesn't really translate well to decimal. Take a look at the standard if you're interested.
You should be able to use the .RemoveNode method of the node or the .RemoveChild method of the parent node.
As noted in other answers, pthreads does not define a platform-independent way to retrieve an integral thread ID.
On Linux systems, you can get thread ID thus:
#include <sys/types.h>
pid_t tid = gettid();
On many BSD-based platforms, this answer https://stackoverflow.com/a/21206357/316487 gives a non-portable way.
However, if the reason you think you need a thread ID is to know whether you're running on the same or different thread to another thread you control, you might find some utility in this approach
static pthread_t threadA;
// On thread A...
threadA = pthread_self();
// On thread B...
pthread_t threadB = pthread_self();
if (pthread_equal(threadA, threadB)) printf("Thread B is same as thread A.\n");
else printf("Thread B is NOT same as thread A.\n");
If you just need to know if you're on the main thread, there are additional ways, documented in answers to this question how can I tell if pthread_self is the main (first) thread in the process?.
Yes you can start with the Wikipedia article explaining the Big O notation, which in a nutshell is a way of describing the "efficiency" (upper bound of complexity) of different type of algorithms. Or you can look at an earlier answer where this is explained in simple english
Accessing CSS property & manipulating is quite easy using .css(). For example, to change single property:
$("selector").css('top', '50px');
You didn't bind all your bindings here
$sql = "SELECT SQL_CALC_FOUND_ROWS *, UNIX_TIMESTAMP(publicationDate) AS publicationDate FROM comments WHERE articleid = :art
ORDER BY " . mysqli_escape_string($order) . " LIMIT :numRows";
$st = $conn->prepare( $sql );
$st->bindValue( ":art", $art, PDO::PARAM_INT );
You've declared a binding called :numRows but you never actually bind anything to it.
UPDATE 2019: I keep getting upvotes on this and that reminded me of another suggestion
Double quotes are string interpolation in PHP, so if you're going to use variables in a double quotes string, it's pointless to use the concat operator. On the flip side, single quotes are not string interpolation, so if you've only got like one variable at the end of a string it can make sense, or just use it for the whole string.
In fact, there's a micro op available here since the interpreter doesn't care about parsing the string for variables. The boost is nearly unnoticable and totally ignorable on a small scale. However, in a very large application, especially good old legacy monoliths, there can be a noticeable performance increase if strings are used like this. (and IMO, it's easier to read anyway)
print("sorted counting values:-")
from collections import Counter
fname = open(filename)
fname = fname.read()
fsplit = fname.split()
user = Counter(fsplit)
for i,v in sorted(user.items()):
print((v,i))
if the result does not need to be order-preserving, then you can simply use a set
>>> ''.join(set( "aaabcabccd"))
'acbd'
>>>
Use date() function to get the desired date
<?php
// set default timezone
date_default_timezone_set('UTC');
//define date and time
$strtotime = 1307595105;

echo date('d M Y H:i:s',$strtotime);
// more formats
echo date('c',$strtotime); // ISO 8601 format
echo date('r',$strtotime); // RFC 2822 format
?>

Use Intent Preference if you are using preference xml screen or you if you are using you custom screen then the code would be like below
intentClearCookies = getPreferenceManager().createPreferenceScreen(this);
Intent clearcookies = new Intent(PopupPostPref.this, ClearCookies.class);
intentClearCookies.setIntent(clearcookies);
intentClearCookies.setTitle(R.string.ClearCookies);
intentClearCookies.setEnabled(true);
launchPrefCat.addPreference(intentClearCookies);
And then Create Activity Class somewhat like below, As different people as different approach you can use any approach you like this is just an example.
public class ClearCookies extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
showDialog();
}
/**
* @throws NotFoundException
*/
private void showDialog() throws NotFoundException {
new AlertDialog.Builder(this)
.setTitle(getResources().getString(R.string.ClearCookies))
.setMessage(
getResources().getString(R.string.ClearCookieQuestion))
.setIcon(
getResources().getDrawable(
android.R.drawable.ic_dialog_alert))
.setPositiveButton(
getResources().getString(R.string.PostiveYesButton),
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog,
int which) {
//Do Something Here
}
})
.setNegativeButton(
getResources().getString(R.string.NegativeNoButton),
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog,
int which) {
//Do Something Here
}
}).show();
}}
As told before there are number of ways doing this. this is one of the way you can do your task, please accept the answer if you feel that you have got it what you wanted.
You can exchange this local variable for a global, it would be easier.
DROP PROCEDURE IF EXISTS ABC;
DELIMITER $$
CREATE PROCEDURE ABC()
BEGIN
SET @a = 0;
simple_loop: LOOP
SET @a=@a+1;
select @a;
IF @a=5 THEN
LEAVE simple_loop;
END IF;
END LOOP simple_loop;
END $$

The problem, as you've spotted, is that String.Contains
does not perform a word-boundary check, so Contains("float")
will return true
for both "foo float bar" (correct) and "unfloating" (which is incorrect).
The solution is to ensure that "float" (or whatever your desired class-name is) appears alongside a word-boundary at both ends. A word-boundary is either the start (or end) of a string (or line), whitespace, certain punctuation, etc. In most regular-expressions this is \b
. So the regex you want is simply: \bfloat\b
.
A downside to using a Regex
instance is that they can be slow to run if you don't use the .Compiled
option - and they can be slow to compile. So you should cache the regex instance. This is more difficult if the class-name you're looking for changes at runtime.
Alternatively you can search a string for words by word-boundaries without using a regex by implementing the regex as a C# string-processing function, being careful not to cause any new string or other object allocation (e.g. not using String.Split
).
Suppose you just want to look for elements with a single, design-time specified class-name:
class Program {
private static readonly Regex _classNameRegex = new Regex( @"\bfloat\b", RegexOptions.Compiled );
private static IEnumerable<HtmlNode> GetFloatElements(HtmlDocument doc) {
return doc
.Descendants()
.Where( n => n.NodeType == NodeType.Element )
.Where( e => e.Name == "div" && _classNameRegex.IsMatch( e.GetAttributeValue("class", "") ) );
}
}
If you need to choose a single class-name at runtime then you can build a regex:
private static IEnumerable<HtmlNode> GetElementsWithClass(HtmlDocument doc, String className) {
Regex regex = new Regex( "\\b" + Regex.Escape( className ) + "\\b", RegexOptions.Compiled );
return doc
.Descendants()
.Where( n => n.NodeType == NodeType.Element )
.Where( e => e.Name == "div" && regex.IsMatch( e.GetAttributeValue("class", "") ) );
}
If you have multiple class-names and you want to match all of them, you could create an array of Regex
objects and ensure they're all matching, or combine them into a single Regex
using lookarounds, but this results in horrendously complicated expressions - so using a Regex[]
is probably better:
using System.Linq;
private static IEnumerable<HtmlNode> GetElementsWithClass(HtmlDocument doc, String[] classNames) {
Regex[] exprs = new Regex[ classNames.Length ];
for( Int32 i = 0; i < exprs.Length; i++ ) {
exprs[i] = new Regex( "\\b" + Regex.Escape( classNames[i] ) + "\\b", RegexOptions.Compiled );
}
return doc
.Descendants()
.Where( n => n.NodeType == NodeType.Element )
.Where( e =>
e.Name == "div" &&
exprs.All( r =>
r.IsMatch( e.GetAttributeValue("class", "") )
)
);
}
The advantage of using a custom C# method to do string matching instead of a regex is hypothetically faster performance and reduced memory usage (though Regex
may be faster in some circumstances - always profile your code first, kids!)
This method below: CheapClassListContains
provides a fast word-boundary-checking string matching function that can be used the same way as regex.IsMatch
:
private static IEnumerable<HtmlNode> GetElementsWithClass(HtmlDocument doc, String className) {
return doc
.Descendants()
.Where( n => n.NodeType == NodeType.Element )
.Where( e =>
e.Name == "div" &&
CheapClassListContains(
e.GetAttributeValue("class", ""),
className,
StringComparison.Ordinal
)
);
}
/// <summary>Performs optionally-whitespace-padded string search without new string allocations.</summary>
/// <remarks>A regex might also work, but constructing a new regex every time this method is called would be expensive.</remarks>
private static Boolean CheapClassListContains(String haystack, String needle, StringComparison comparison)
{
if( String.Equals( haystack, needle, comparison ) ) return true;
Int32 idx = 0;
while( idx + needle.Length <= haystack.Length )
{
idx = haystack.IndexOf( needle, idx, comparison );
if( idx == -1 ) return false;
Int32 end = idx + needle.Length;
// Needle must be enclosed in whitespace or be at the start/end of string
Boolean validStart = idx == 0 || Char.IsWhiteSpace( haystack[idx - 1] );
Boolean validEnd = end == haystack.Length || Char.IsWhiteSpace( haystack[end] );
if( validStart && validEnd ) return true;
idx++;
}
return false;
}
HtmlAgilityPack is somewhat stagnated doesn't support .querySelector
and .querySelectorAll
, but there are third-party libraries that extend HtmlAgilityPack with it: namely Fizzler and CssSelectors. Both Fizzler and CssSelectors implement QuerySelectorAll
, so you can use it like so:
private static IEnumerable<HtmlNode> GetDivElementsWithFloatClass(HtmlDocument doc) {
return doc.QuerySelectorAll( "div.float" );
}
With runtime-defined classes:
private static IEnumerable<HtmlNode> GetDivElementsWithClasses(HtmlDocument doc, IEnumerable<String> classNames) {
String selector = "div." + String.Join( ".", classNames );
return doc.QuerySelectorAll( selector );
}
On a large iteration I like using interrupts. Just press Ctrl + C to quit:
my $exitflag = 0;
$SIG{INT} = sub { $exitflag=1 };
while(!$exitflag) {
# Do your stuff
}
I reached this thread when I am using pure command line/jenkins build script and I don't want any single UI/RDP manually setup for the integration environment.
After a few hours try to solve exactly the same issue using jenkins.
The key is "security list-keychains -s <your_keychain_name>"
--- Long story ---
I use a script in jenkins to override per-project settings (provisioning profile and signing identities)
After upgrade to Xcode 7, I have to change the script add above "list-keychains" after "create-keychains"
