You can use following as well
<string name="spelatonertext3"> "-4, 5, -5, 6, -6, "> </string>
Put anything in " "
(quotation) with space, and it should work
Depends what you mean by a pattern. If you're thinking Person/Company/Transaction/Product and such, then yes - there are a lot of generic database schemas already available.
If you're thinking Factory, Singleton... then no - you don't need any of these as they're too low level for DB programming.
If you're thinking database object naming, then it's under the category of conventions, not design per se.
BTW, S.Lott, one-to-many and many-to-many relationships aren't "patterns". They're the basic building blocks of the relational model.
You have two options, a PL/SQL block or SQL*Plus bind variables:
var z number
execute my_stored_proc (-1,2,0.01,:z)
print z
You have to add writing rights to the directory in which your sqlite database is stored. So running chmod 664 /srv/mysite
should help.
This is a security risk, so better solution is to change the owner of your database to www-data
:
chown www-data:www-data /srv/mysite
chown www-data:www-data /srv/mysite/DATABASE.sqlite

I wrote this to remove all objects apart from functions from the current environment (Programming language used is R with IDE R-Studio):
remove_list=c() # create a vector
for(i in 1:NROW(ls())){ # repeat over all objects in environment
if(class(get(ls()[i]))!="function"){ # if object is *not* a function
remove_list=c(remove_list,ls()[i]) # ..add to vector remove_list
}
}
rm(list=remove_list) # remove all objects named in remove_list
Notes-
The argument "list" in rm(list=) must be a character vector.
The name of an object in position i of the current environment is returned from ls()[i] and the object itself from get(ls()[i]). Therefore the class of an object is returned from class(get(ls()[i]))
Simple Use of const
.
The simplest use is to declare a named constant. To do this, one declares a constant as if it was a variable but add const
before it. One has to initialize it immediately in the constructor because, of course, one cannot set the value later as that would be altering it. For example:
const int Constant1=96;
will create an integer constant, unimaginatively called Constant1
, with the value 96.
Such constants are useful for parameters which are used in the program but are do not need to be changed after the program is compiled. It has an advantage for programmers over the C preprocessor #define
command in that it is understood & used by the compiler itself, not just substituted into the program text by the preprocessor before reaching the main compiler, so error messages are much more helpful.
It also works with pointers but one has to be careful where const
to determine whether the pointer or what it points to is constant or both. For example:
const int * Constant2
declares that Constant2
is variable pointer to a constant integer and:
int const * Constant2
is an alternative syntax which does the same, whereas
int * const Constant3
declares that Constant3
is constant pointer to a variable integer and
int const * const Constant4
declares that Constant4
is constant pointer to a constant integer. Basically ‘const’ applies to whatever is on its immediate left (other than if there is nothing there in which case it applies to whatever is its immediate right).

Try:
C:\Users\USERNAME\.nuget\packages\
That worked for me.
Ok guys I found a possible solution to this problem. I realized that joins do not exists in Mongo, that's why first you need to query the user's ids with the role you like, and after that do another query to the profiles document, something like this:
const exclude: string = '-_id -created_at -gallery -wallet -MaxRequestersPerBooking -active -__v';
// Get the _ids of users with the role equal to role.
await User.find({role: role}, {_id: 1, role: 1, name: 1}, function(err, docs) {
// Map the docs into an array of just the _ids
var ids = docs.map(function(doc) { return doc._id; });
// Get the profiles whose users are in that set.
Profile.find({user: {$in: ids}}, function(err, profiles) {
// docs contains your answer
res.json({
code: 200,
profiles: profiles,
page: page
})
})
.select(exclude)
.populate({
path: 'user',
select: '-password -verified -_id -__v'
// group: { role: "$role"}
})
});
AndroidManifest.xml

I always use DATETIME fields for anything other than row metadata (date created or modified).
As mentioned in the MySQL documentation:
The DATETIME type is used when you need values that contain both date and time information. MySQL retrieves and displays DATETIME values in 'YYYY-MM-DD HH:MM:SS' format. The supported range is '1000-01-01 00:00:00' to '9999-12-31 23:59:59'.
...
The TIMESTAMP data type has a range of '1970-01-01 00:00:01' UTC to '2038-01-09 03:14:07' UTC. It has varying properties, depending on the MySQL version and the SQL mode the server is running in.
You're quite likely to hit the lower limit on TIMESTAMPs in general use -- e.g. storing birthdate.
The other answers all mention text-decoration. Sometimes you use a Wordpress theme or someone else's CSS where links are underlined by other methods, so that text-decoration: none won't turn off the underlining.
Border and box-shadow are two other methods I'm aware of for underlining links. To turn these off:
border: none;
and
box-shadow: none;
Alexis has already posted an answer in Java 8 using method toMap(keyMapper, valueMapper)
. As per doc for this method implementation:
There are no guarantees on the type, mutability, serializability, or thread-safety of the Map returned.
So in case we are interested in a specific implementation of Map
interface e.g. HashMap
then we can use the overloaded form as:
Map<String, Item> map2 =
itemList.stream().collect(Collectors.toMap(Item::getKey, //key for map
Function.identity(), // value for map
(o,n) -> o, // merge function in case of conflict with keys
HashMap::new)); // map factory - we want HashMap and not any Map implementation
Though using either Function.identity()
or i->i
is fine but it seems Function.identity()
instead of i -> i
might save some memory as per this related answer.
If you use the InnoDB storage engine for (some of) your MySQL tables, you’ve probably already came across a problem with its default configuration. As you may have noticed in your MySQL’s data directory (in Debian/Ubuntu – /var/lib/mysql) lies a file called ‘ibdata1'. It holds almost all the InnoDB data (it’s not a transaction log) of the MySQL instance and could get quite big. By default this file has a initial size of 10Mb and it automatically extends. Unfortunately, by design InnoDB data files cannot be shrinked. That’s why DELETEs, TRUNCATEs, DROPs, etc. will not reclaim the space used by the file.
I think you can find good explanation and solution there :
It would be fairly easy to force the web browser to display the page with the same pixel dimensions as A4. However, there may be a few quirks when things are rendered.
Assuming your monitors display 72 dpi, you could add something like this:
<!DOCTYPE html>
<html>
<head>
<style>
body {
height: 842px;
width: 595px;
/* to centre page on screen*/
margin-left: auto;
margin-right: auto;
}
</style>
</head>
<body>
</body>
</html>
The CPPFLAGS
macro is the one to use to specify #include
directories.
Both CPPFLAGS
and CFLAGS
work in your case because the make
(1) rule combines both preprocessing and compiling in one command (so both macros are used in the command).
You don't need to specify .
as an include-directory if you use the form #include "..."
. You also don't need to specify the standard compiler include directory. You do need to specify all other include-directories.
Try a javascript pure:
Library JS:
appendHtml = function(element, html) {
var div = document.createElement('div');
div.innerHTML = html;
while (div.children.length > 0) {
element.appendChild(div.children[0]);
}
}
Type:
appendHtml(document.head, '<link rel="stylesheet" type="text/css" href="http://example.com/example.css"/>');
or jQuery:
$('head').append($('<link rel="stylesheet" type="text/css" />').attr('href', 'http://example.com/example.css'));

public class Average {
public static void main(String [] args) {
String test1= JOptionPane.showInputDialog("Please input mark for test 1: ");
String test2= JOptionPane.showInputDialog("Please input mark for test 2: ");
String test3= JOptionPane.showInputDialog("Please input mark for test 3: ");
int int1 = Integer.parseInt(test1);
int int2 = Integer.parseInt(test2);
int int3 = Integer.parseInt(test3);
SortedSet<Integer> set = new TreeSet<>();
set.add(int1);
set.add(int2);
set.add(int3);
Integer [] intArray = set.toArray(new Integer[3]);
JFrame frame = new JFrame();
JOptionPane.showInternalMessageDialog(frame.getContentPane(), String.format("Result %f", (intArray[1] + intArray[2]) / 2.0));
}
}
One way to format it is:
printf("%lld.%.9ld", (long long)ts.tv_sec, ts.tv_nsec);
Simple and neat solution involving some good answers and comment.
<img src="foo.jpg" onerror="this.src='error.jpg';this.onerror='';">
It even solve infinite loop risk.
Worked for me.
From Xcode 8.3 onward Build Settings
has key Swift Language Version
with a value of swift version your target is using.
For older Xcodes use this solution, open terminal and type following command(s)
Case 1: You have installed only one Xcode App
swift -version
Case 2: You have installed multiple Xcode Apps
Switch active developer directory
(Replace Xcode_7.3.app
from
following command with your Xcode app file name from Application directory for which you want
to check swift version)
sudo xcode-select --switch /Applications/Xcode_7.3.app/Contents/Developer
Then
swift -version
NOTE: From Xcode 8 to Xcode 8.2.x you can use swift 2.3 even though Xcode 8 uses swift 3.x as default swift version. To use swift 2.3, just turn on flag Use Legacy Swift Language Version
to YES
from Build Setting
and XCode will use Swift 2.3 for that project target.
CSS3 introduced flexible boxes (aka. flex box) which can also achieve this behavior.
Simply define the width of the first div, and then give the second a flex-grow
value of 1
which will allow it to fill the remaining width of the parent.
.container{
display: flex;
}
.fixed{
width: 200px;
}
.flex-item{
flex-grow: 1;
}
<div class="container">
<div class="fixed"></div>
<div class="flex-item"></div>
</div>
Demo:
div {
color: #fff;
font-family: Tahoma, Verdana, Segoe, sans-serif;
padding: 10px;
}
.container {
background-color:#2E4272;
display:flex;
}
.fixed {
background-color:#4F628E;
width: 200px;
}
.flex-item {
background-color:#7887AB;
flex-grow: 1;
}
_x000D_
<div class="container">
<div class="fixed">Fixed width</div>
<div class="flex-item">Dynamically sized content</div>
</div>
_x000D_
Note that flex boxes are not backwards compatible with old browsers, but is a great option for targeting modern browsers (see also Caniuse and MDN). A great comprehensive guide on how to use flex boxes is available on CSS Tricks.
Your error looks like you are duplicating an already existing Primary Key in your DB. You should modify your sql code to implement its own primary key by using something like the IDENTITY keyword.
CREATE TABLE [DB] (
[DBId] bigint NOT NULL IDENTITY,
...
CONSTRAINT [DB_PK] PRIMARY KEY ([DB] ASC),
);
I was suffering from this problem for long times.
I had about 100 projects different version was deployed in different server.
Updating xunit from 2.2.0 to 2.3.1 was not a solution because build was failing in 2.3.1.
Then I just updated xunit.runner.visualstudio to 2.3.1 and everything started to work fine. I have used this command in my package manager console to updated my xunit.runner.visualstudio package
Get-Project ComapanyName.ProjectName.*.Tests | Install-Package xunit.runner.visualstudio -Version 2.3.1
Make sure that your sas.png
is marked as Build Action: Content
and Copy To Output Directory: Copy Always
in its Visual Studio Properties
...
I think the C# source code goes like this...
Image image = new Image();
image.Source = (new ImageSourceConverter()).ConvertFromString("pack://application:,,,/Bilder/sas.png") as ImageSource;
and XAML should be
<Image Height="200" HorizontalAlignment="Left" Margin="12,12,0,0"
Name="image1" Stretch="Fill" VerticalAlignment="Top"
Source="../Bilder/sas.png"
Width="350" />
EDIT
Dynamically I think XAML would provide best way to load Images ...
<Image Source="{Binding Converter={StaticResource MyImageSourceConverter}}"
x:Name="MyImage"/>
where image.DataContext
is string
path.
MyImage.DataContext = "pack://application:,,,/Bilder/sas.png";
public class MyImageSourceConverter : IValueConverter
{
public object Convert(object value_, Type targetType_,
object parameter_, System.Globalization.CultureInfo culture_)
{
return (new ImageSourceConverter()).ConvertFromString (value.ToString());
}
public object ConvertBack(object value, Type targetType,
object parameter, CultureInfo culture)
{
throw new NotImplementedException();
}
}
Now as you set a different data context, Image
would be automatically loaded at runtime.
Try one of the statements below:
$('input[type=submit]').attr('disabled','disabled');
or
$('input[type=button]').attr('disabled','disabled');
UPDATE
To target a particular button, given the HTML you provided:
$('div#DT1S input[type=button]').attr('disabled','disabled');
int index= datagridview.rows.add();
datagridview.rows[index].cells[1].value=1;
datagridview.rows[index].cells[2].value="a";
datagridview.rows[index].cells[3].value="b";
hope this help! :)
You have a few typos in your select. It should be: input:not([disabled]):not([type="submit"]):focus
See this jsFiddle for a proof of concept. On a sidenote, if I removed the "background-color" property, then the box shadow no longer works. Not sure why.
For everyone looking for the log of the binomial coefficient (Theano calls this binomln
), this answer has it:
from numpy import log
from scipy.special import betaln
def binomln(n, k):
"Log of scipy.special.binom calculated entirely in the log domain"
return -betaln(1 + n - k, 1 + k) - log(n + 1)
(And if your language/library lacks betaln
but has gammaln
, like Go, have no fear, since betaln(a, b)
is just gammaln(a) + gammaln(b) - gammaln(a + b)
, per MathWorld.)
Today I came across multiple solutions for this. Running the async await functions in the forEach Loop. By building the wrapper around we can make this happen.
The multiple ways through which it can be done and they are as follows,
Method 1 : Using the wrapper.
await (()=>{
return new Promise((resolve,reject)=>{
items.forEach(async (item,index)=>{
try{
await someAPICall();
} catch(e) {
console.log(e)
}
count++;
if(index === items.length-1){
resolve('Done')
}
});
});
})();
Method 2: Using the same as a generic function of Array.prototype
Array.prototype.forEachAsync.js
if(!Array.prototype.forEachAsync) {
Array.prototype.forEachAsync = function (fn){
return new Promise((resolve,reject)=>{
this.forEach(async(item,index,array)=>{
await fn(item,index,array);
if(index === array.length-1){
resolve('done');
}
})
});
};
}
Usage :
require('./Array.prototype.forEachAsync');
let count = 0;
let hello = async (items) => {
// Method 1 - Using the Array.prototype.forEach
await items.forEachAsync(async () => {
try{
await someAPICall();
} catch(e) {
console.log(e)
}
count++;
});
console.log("count = " + count);
}
someAPICall = () => {
return new Promise((resolve, reject) => {
setTimeout(() => {
resolve("done") // or reject('error')
}, 100);
})
}
hello(['', '', '', '']); // hello([]) empty array is also be handled by default
Method 3 :
Using Promise.all
await Promise.all(items.map(async (item) => {
await someAPICall();
count++;
}));
console.log("count = " + count);
Method 4 : Traditional for loop or modern for loop
// Method 4 - using for loop directly
// 1. Using the modern for(.. in..) loop
for(item in items){
await someAPICall();
count++;
}
//2. Using the traditional for loop
for(let i=0;i<items.length;i++){
await someAPICall();
count++;
}
console.log("count = " + count);
If you can't find it in numpy or scipy, here are a couple of quick functions and a point class:
import math
def rect(r, theta):
"""theta in degrees

x = r * math.cos(math.radians(theta))

r = (x ** 2 + y ** 2) ** .5
theta = math.degrees(math.atan2(y,x))
return r, theta
class Point(object):
def __init__(self, x=None, y=None, r=None, theta=None):
"""x and y or r and theta(degrees)

if x and y:
self.c_polar(x, y)
elif r and theta:
self.c_rect(r, theta)

raise ValueError('Must specify x and y or r and theta')
def c_polar(self, x, y, f = polar):
self._x = x

I'll sometimes do this:
def draw_menu(options, selected_index):
for i in range(len(options)):
if i == selected_index:
print " [*] %s" % options[i]
else:
print " [ ] %s" % options[i]
Though I tend to avoid this if it means I'll be saying options[i]
more than a couple of times.
In Linear Search (as per exercise given in book), we need to find value V in given array.
Its simple as scanning the array from 0 <= k < length and comparing each element. If V found, or if scanning reaches length of array, just terminate the loop.
As per my understanding in above problem-
Loop Invariants(Initialization): V is not found in k - 1 iteration. Very first iteration, this would be -1 hence we can say V not found at position -1
Maintainance: In next iteration,V not found in k-1 holds true
Terminatation: If V found in k position or k reaches the length of the array, terminate the loop.
You should use a form of Math.Round
. Be aware that Math.Round
defaults to banker's rounding (rounding to the nearest even number) unless you specify a MidpointRounding
value. If you don't want to use banker's rounding, you should use Math.Round(decimal d, int decimals, MidpointRounding mode)
, like so:
Math.Round(pay, 2, MidpointRounding.AwayFromZero); // .005 rounds up to 0.01
Math.Round(pay, 2, MidpointRounding.ToEven); // .005 rounds to nearest even (0.00)
Math.Round(pay, 2); // Defaults to MidpointRounding.ToEven
In the accepted answer you get annoying spacing between the visible rows when the expandable row is hidden. You can get rid of that by adding this to css:
.collapse-row.collapsed + tr {
display: none;
}
'+' is adjacent sibling selector, so if you want your expandable row to be the next row, this selects the next tr following tr named collapse-row.
Here is updated fiddle: http://jsfiddle.net/Nb7wy/2372/
There doesn't seem to be a standardized default value. I have the feeling the default is 0
, and the timeout event left totally dependent on browser and network settings.
For IE, there is a timeout property for XMLHTTPRequests here. It defaults to null, and it says the network stack is likely to be the first to time out (which will not generate an ontimeout event by the way).
For excluding multiple file types, you can use '+' to concatenate other lists. For example:
xcopy /r /d /i /s /y /exclude:excludedfileslist1.txt+excludedfileslist2.txt C:\dev\apan C:\web\apan
Source: http://www.tech-recipes.com/rx/2682/xcopy_command_using_the_exclude_flag/
for integer 'X' you want to know the number of digits , alright without using any loop , this solution act in one formula in one line only so this is the most optimal solution i have ever seen to this problem .
int x = 1000 ;
cout<<numberOfDigits = 1+floor(log10(x))<<endl ;
If this webserver is only for testing and demoing purposes. You can use ngrok, a open source too that tunnels your http traffic.
Bascially ngrok creates a public URL (both http and https) and then tunnels the traffic to whatever port your Flask process is running on.
It only takes a couple minutes to set up. You first have to download the software. Then run the command
./ngrok http [port number your python process is running on]
It will then open up a window in terminal giving you both an http and https url to access your web app.
You are right about HashTable
, you can forget about it.
Your article mentions the fact that while HashTable and the synchronized wrapper class provide basic thread-safety by only allowing one thread at a time to access the map, this is not 'true' thread-safety since many compound operations still require additional synchronization, for example:
synchronized (records) {
Record rec = records.get(id);
if (rec == null) {
rec = new Record(id);
records.put(id, rec);
}
return rec;
}
However, don't think that ConcurrentHashMap
is a simple alternative for a HashMap
with a typical synchronized
block as shown above. Read this article to understand its intricacies better.
Add this 2 lines in your code -
mWebView.setWebChromeClient(new WebChromeClient());
mWebView.setWebViewClient(new WebViewClient());?
emplace_back
conforming implementation will forward arguments to the vector<Object>::value_type
constructor when added to the vector. I recall Visual Studio didn't support variadic templates, but with variadic templates will be supported in Visual Studio 2013 RC, so I guess a conforming signature will be added.
With emplace_back
, if you forward the arguments directly to vector<Object>::value_type
constructor, you don't need a type to be movable or copyable for emplace_back
function, strictly speaking. In the vector<NonCopyableNonMovableObject>
case, this is not useful, since vector<Object>::value_type
needs a copyable or movable type to grow.
But note that this could be useful for std::map<Key, NonCopyableNonMovableObject>
, since once you allocate an entry in the map, it doesn't need to be moved or copied ever anymore, unlike with vector
, meaning that you can use std::map
effectively with a mapped type that is neither copyable nor movable.
Simplest way? It works. :)
Dim queryString As String = "Stor_Proc_Name " & data1 & "," & data2
Try
Using connection As New SqlConnection(ConnStrg)
connection.Open()
Dim command As New SqlCommand(queryString, connection)
Dim reader As SqlDataReader = command.ExecuteReader()
Dim DTResults As New DataTable
DTResults.Load(reader)
MsgBox(DTResults.Rows(0)(0).ToString)
End Using
Catch ex As Exception
MessageBox.Show("Error while executing .. " & ex.Message, "")
Finally
End Try
create a new class called ComboKeyValue.java
public class ComboKeyValue {
private String key;
private String value;
public ComboKeyValue(String key, String value) {
this.key = key;
this.value = value;
}
@Override
public String toString(){
return key;
}
public String getKey() {
return key;
}
public String getValue() {
return value;
}
}
when you want to add a new item, just write the code as below
DefaultComboBoxModel model = new DefaultComboBoxModel();
model.addElement(new ComboKeyValue("key", "value"));
properties.setModel(model);
JavaScript/jQuery
$("#entersomething").keyup(function(e){
var code = e.key; // recommended to use e.key, it's normalized across devices and languages
if(code==="Enter") e.preventDefault();
if(code===" " || code==="Enter" || code===","|| code===";"){
$("#displaysomething").html($(this).val());
} // missing closing if brace
});
HTML
<input id="entersomething" type="text" /> <!-- put a type attribute in -->
<div id="displaysomething"></div>
You can do something like:
s = np.random.normal(2, 3, 1000)
import matplotlib.pyplot as plt
count, bins, ignored = plt.hist(s, 30, density=True)
plt.plot(bins, 1/(3 * np.sqrt(2 * np.pi)) * np.exp( - (bins - 2)**2 / (2 * 3**2) ),
linewidth=2, color='r')
plt.show()
Hope this helps. From eclipse, you right click the project -> Run As -> Run on Server and then it worked for me. I used Eclipse Jee Neon and Apache Tomcat 9.0. :)
I just removed the head portion in index.html file and it worked fine.This is the head tag in html file
This is working i Angular 8 without setTimeout:
import {AfterContentChecked, Directive, ElementRef} from '@angular/core';
@Directive({
selector: 'input[inputAutoFocus]'
})
export class InputFocusDirective implements AfterContentChecked {
constructor(private element: ElementRef<HTMLInputElement>) {}
ngAfterContentChecked(): void {
this.element.nativeElement.focus();
}
}
Explanation: Ok so this works because of: Change detection. It's the same reason that setTimout works, but when running a setTimeout in Angular it will bypass Zone.js and run all checks again, and it works because when the setTimeout is complete all changes are completed. With the correct lifecycle hook (AfterContentChecked) the same result can be be reached, but with the advantage that the extra cycle won't be run. The function will fire when all changes are checked and passed, and runs after the hooks AfterContentInit and DoCheck. If i'm wrong here please correct me.
More one lifecycles and change detection on https://angular.io/guide/lifecycle-hooks
UPDATE: I found an even better way to do this if one is using Angular Material CDK, the a11y-package. First import A11yModule in the the module declaring the component you have the input-field in. Then use cdkTrapFocus and cdkTrapFocusAutoCapture directives and use like this in html and set tabIndex on the input:
<div class="dropdown" cdkTrapFocus cdkTrapFocusAutoCapture>
<input type="text tabIndex="0">
</div>
We had some issues with our dropdowns regarding positioning and responsiveness and started using the OverlayModule from the cdk instead, and this method using A11yModule works flawlessly.
If you're referring to the concept of accessors, then the simple goal is to hide the underlying storage from arbitrary manipulation. The most extreme mechanism for this is
function Foo(someValue) {
this.getValue = function() { return someValue; }
return this;
}
var myFoo = new Foo(5);
/* We can read someValue through getValue(), but there is no mechanism
* to modify it -- hurrah, we have achieved encapsulation!
*/
myFoo.getValue();
If you're referring to the actual JS getter/setter feature, eg. defineGetter
/defineSetter
, or { get Foo() { /* code */ } }
, then it's worth noting that in most modern engines subsequent usage of those properties will be much much slower than it would otherwise be. eg. compare performance of
var a = { getValue: function(){ return 5; }; }
for (var i = 0; i < 100000; i++)
a.getValue();
vs.
var a = { get value(){ return 5; }; }
for (var i = 0; i < 100000; i++)
a.value;

There is a probably a better “command line” way to do this, and I know this is a hack, but I’ve never been able to find a good solution.
Using TortoiseGIT: If you have a GIT commit where some file move operations are showing up as load of adds/deletes rather than renames, even though the files only have small changes, then do this:
The new commit will now properly show the file renames… which will help maintain proper file history.

ken's answer above did the trick for me. The problem with the accepted answer is that it only works if you have a single modal on the page. If you have multiple modals, you'll need to do it inline in the "open" param while initializing the dialog, not after the fact.
open: function(type,data) { $(this).parent().appendTo("form"); }
If you do what the first accepted answer tells you with multiple modals, you'll only get the last modal on the page working firing postbacks properly, not all of them.
You can use the parameter -f
(or --file
) and specify the path to your pom file, e.g. mvn -f /path/to/pom.xml
This runs maven "as if" it were in /path/to
for the working directory.

I had similar issue when I had plenty of extra records in csv file with empty values. If I open csv file in notepad then empty lines looks like this: ,,,, ,,,, ,,,, ,,,,
You can not see those if open in Excel. Please check in Notepad and delete those records

This may or may not be a sub-optimal way of doing things, but the simplest solution to the multi-page problem I found was to ensure all rendering is done before calling the jsPDFObj.save method.
As for rendering hidden articles, this is solved with a similar fix to css image text replacement, I position absolutely the element to be rendered -9999px off the page left,
this doesn't affect layout and allows for the elem to be visible to html2pdf, especially when using tabs, accordions and other UI components that depend on {display: none}
.
This method wraps the prerequisites in a promise and calls pdf.save()
in the finally()
method. I cannot be sure that this is foolproof, or an anti-pattern, but it would seem that it works in most cases I have thrown at it.

Substring. This method extracts strings. It requires the location of the substring (a start index, a length). It then returns a new string with the characters in that range.
See a small example :
string input = "OneTwoThree";
// Get first three characters.
string sub = input.Substring(0, 3);
Console.WriteLine("Substring: {0}", sub);
Output : Substring: One
Try to encapsulate the ajax call into a function and set the async option to false. Note that this option is deprecated since jQuery 1.8.
function foo() {
var myajax = $.ajax({
type: "POST",
url: "CHService.asmx/SavePurpose",
dataType: "text",
data: JSON.stringify({ Vid: Vid, PurpId: PurId }),
contentType: "application/json; charset=utf-8",
async: false, //add this
});
return myajax.responseText;
}
You can do this also:
$.ajax({
type: "POST",
url: "CHService.asmx/SavePurpose",
dataType: "text",
data: JSON.stringify({ Vid: Vid, PurpId: PurId }),
contentType: "application/json; charset=utf-8",
async: false, //add this
}).done(function ( data ) {
Success = true;
}).fail(function ( data ) {
Success = false;
});

The best and easiest method is to base64 encode the font file. And use it in font-face. For encoding, go to the folder having the font-file and use the command in terminal:
base64 Roboto.ttf > basecodedtext.txt
You will get an output file named basecodedtext.txt. Open that file. Remove any white spaces in that.
Copy that code and add the following line to the CSS file:
@font-face {
font-family: "font-name";
src: url(data:application/x-font-woff;charset=utf-8;base64,<<paste your code here>>) format('woff');
}
Then you can use the font-family: "font-name"
in your CSS.
if rate is the sampling rate(Hz), then np.linspace(0, rate/2, n)
is the frequency array of every point in fft. You can use rfft
to calculate the fft in your data is real values:
import numpy as np
import pylab as pl
rate = 30.0
t = np.arange(0, 10, 1/rate)
x = np.sin(2*np.pi*4*t) + np.sin(2*np.pi*7*t) + np.random.randn(len(t))*0.2
p = 20*np.log10(np.abs(np.fft.rfft(x)))
f = np.linspace(0, rate/2, len(p))
plot(f, p)
signal x contains 4Hz & 7Hz sin wave, so there are two peaks at 4Hz & 7Hz.

for (String s : children) {
if (!s.equals("lib")) {
deleteDir(new File(appDir, s));Log.i("TAG", "**************** File /data/data/APP_PACKAGE/" + s + " DELETED *******************");
}
}
}
}
public static boolean deleteDir(File dir) {
if (dir != null && dir.isDirectory()) {
String[] children = dir.list();
for (int i = 0; i < children.length; i++) {
boolean success = deleteDir(new File(dir, children[i]));
if (!success) {
return false;
}
}
}
return dir.delete();
}

Quick review,
From x86 assembly tutorial,
The pop instruction removes the 4-byte data element from the top of the hardware-supported stack into the specified operand (i.e. register or memory location). It first moves the 4 bytes located at memory location [SP] into the specified register or memory location, and then increments SP by 4.
Your num is 1 byte. Try declaring it with DD
so that it becomes 4 bytes and matches with pop
semantics.

Example of using border-collapse: separate; as
ol[type="I"]>li{
display: table;
border-collapse: separate;
border-spacing: 1rem;
}
There is a easy way to do this. It only takes a couple steps and you don't need to use the command line too much. If you new to the command line this is the way to do it.
Step 1 : Finding the bin file to put the subl executable file in
cd ..
---------------------this should go back a directoryls
------------------------to see a list of files in the directorycd ..
---------------------until you get a folder that contains usropen usr
---------------this should open the finder and you should see some foldersStep 2: Finding the executable file
subl
--------------this should open Sublime TextMake sure that it gets copied and it's not a shortcut. If you do have a problem, view the usr/bin folder as icons and paste the subl in a empty area in the folder. It should not have a shortcut arrow in the icon image.
I tried both .empty()
as well as .remove()
for my dropdown and both were slow. Since I had almost 4,000 options there.
I used .html("")
which is much faster in my condition.
Which is below
$(dropdown).html("");
File protocol URIs are like this
file://[HOST]/[PATH]
that's why you often see file URLs like this (3 slashes) file:///c:\path...
So if the host is server01, you want
file://server01/folder/path....
This is according to the wikipedia page on file:// protocols and checks out with .NET's Uri.IsWellFormedUriString method.
We call it the "ant" menu. Guess it was a good time to change since everyone had just gotten used to the hamburger.
Implementation with Guzzle library:
use GuzzleHttp\Client;
use GuzzleHttp\RequestOptions;
$httpClient = new Client();
$response = $httpClient->post(
'https://postman-echo.com/post',
[
RequestOptions::BODY => 'POST raw request content',
RequestOptions::HEADERS => [
'Content-Type' => 'application/x-www-form-urlencoded',
],
]
);
echo(
$response->getBody()->getContents()
);
PHP CURL extension:
$curlHandler = curl_init();
curl_setopt_array($curlHandler, [
CURLOPT_URL => 'https://postman-echo.com/post',
CURLOPT_RETURNTRANSFER => true,
/**
* Specify POST method
*/
CURLOPT_POST => true,
/**
* Specify request content
*/
CURLOPT_POSTFIELDS => 'POST raw request content',
]);
$response = curl_exec($curlHandler);
curl_close($curlHandler);
echo($response);
This might be due to the fact that you are trying to add a ListBoxItem with a same name to the page.
If you want to refresh the content of the listbox with the newly retrieved values you will have to first manually remove the content of the listbox other wise your loop will try to create lb_1 again and add it to the same list.
Look at here for a similar problem that occured Silverlight: Value does not fall within the expected range exception

The middleware extension needs to be called in the Configure method of the service Startup class
public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
loggerFactory.AddConsole(Configuration.GetSection("Logging"));
loggerFactory.AddDebug();
app.UseMiddleware<AuthenticationMiddleware>();
app.UseMvc();
}
And that's all! :)

Solution for HTTP Status 404
in NetBeans IDE:
Right click on your project and go to your project properties, then click on run, then input your project relative URL like index.jsp
.
You need to go to user accounts and enable Guest Account, its default disabled. Once you do this, you share any folder and add the guest account to the list of users who can accesss that specific folder, this also includes to Turn off password Protected Sharing in 'Advanced Sharing Settings'
The other way to do this where you only enter a password once is to join a Homegroup. if you have a network of 2 or more computers, they can all connect to a homegroup and access all the files they need from each other, and anyone outside the group needs a 1 time password to be able to access your network, this was introduced in windows 7.
You cannot calculate the differences separately ... what difference would that yield for 7:59 and 8:00 o'clock? Try
import time
time.time()
which gives you the seconds since the start of the epoch.
You can then get the intermediate time with something like
timestamp1 = time.time()
# Your code here
timestamp2 = time.time()
print "This took %.2f seconds" % (timestamp2 - timestamp1)
For 1D array, numpy.correlate
is faster than scipy.signal.correlate
, under different sizes, I see a consistent 5x peformance gain using numpy.correlate
. When two arrays are of similar size (the bright line connecting the diagonal), the performance difference is even more outstanding (50x +).
# a simple benchmark
res = []
for x in range(1, 1000):
list_x = []
for y in range(1, 1000):
# generate different sizes of series to compare
l1 = np.random.choice(range(1, 100), size=x)
l2 = np.random.choice(range(1, 100), size=y)
time_start = datetime.now()
np.correlate(a=l1, v=l2)
t_np = datetime.now() - time_start
time_start = datetime.now()
scipy.signal.correlate(in1=l1, in2=l2)
t_scipy = datetime.now() - time_start
list_x.append(t_scipy / t_np)
res.append(list_x)
plt.imshow(np.matrix(res))
As default, scipy.signal.correlate calculates a few extra numbers by padding and that might explained the performance difference.
>> l1 = [1,2,3,2,1,2,3]
>> l2 = [1,2,3]
>> print(numpy.correlate(a=l1, v=l2))
>> print(scipy.signal.correlate(in1=l1, in2=l2))
[14 14 10 10 14]
[ 3 8 14 14 10 10 14 8 3] # the first 3 is [0,0,1]dot[1,2,3]
I cared about the file's original end line characters ("\n" or "\r\n") and wanted to maintain them in the output file (not overwrite them with what ever the current environment's char(s) are like the other answers appear to do). So I wrote my own method to read a line without removing the end line chars then used it in my DeleteLines
method (I wanted the option to delete multiple lines, hence the use of a collection of line numbers to delete).
DeleteLines
was implemented as a FileInfo
extension and ReadLineKeepNewLineChars
a StreamReader
extension (but obviously you don't have to keep it that way).
public static class FileInfoExtensions
{
public static FileInfo DeleteLines(this FileInfo source, ICollection<int> lineNumbers, string targetFilePath)
{
var lineCount = 1;
using (var streamReader = new StreamReader(source.FullName))
{
using (var streamWriter = new StreamWriter(targetFilePath))
{
string line;
while ((line = streamReader.ReadLineKeepNewLineChars()) != null)
{
if (!lineNumbers.Contains(lineCount))
{
streamWriter.Write(line);
}
lineCount++;
}
}
}
return new FileInfo(targetFilePath);
}
}
public static class StreamReaderExtensions
{
private const char EndOfFile = '\uffff';
/// <summary>
/// Reads a line, similar to ReadLine method, but keeps any
/// new line characters (e.g. "\r\n" or "\n").
/// </summary>
public static string ReadLineKeepNewLineChars(this StreamReader source)
{
if (source == null)
throw new ArgumentNullException(nameof(source));
char ch = (char)source.Read();
if (ch == EndOfFile)
return null;
var sb = new StringBuilder();
while (ch != EndOfFile)
{
sb.Append(ch);
if (ch == '\n')
break;
ch = (char) source.Read();
}
return sb.ToString();
}
}
If you use instanceof
, making your equals
implementation final
will preserve the symmetry contract of the method: x.equals(y) == y.equals(x)
. If final
seems restrictive, carefully examine your notion of object equivalence to make sure that your overriding implementations fully maintain the contract established by the Object
class.
You can cast this value to a Boolean in a very simple manner: by comparing it with integer value 1, like this:
boolean multipleContacts = new Integer(1).equals(jsonObject.get("MultipleContacts"))
If it is a String, you could do this:
boolean multipleContacts = "1".equals(jsonObject.get("MultipleContacts"))
As I found by the previous answers, three steps are needed to change the type of a column:
Step 1:
Generate a new migration file using this code:
rails g migration sample_name_change_column_type
Step 2:
Go to /db/migrate
folder and edit the migration file you made. There are two different solutions.
def change
change_column(:table_name, :column_name, :new_type)
end
2.
def up
change_column :table_name, :column_name, :new_type
end
def down
change_column :table_name, :column_name, :old_type
end
Step 3:
Don't forget to do this command:
rake db:migrate
I have tested this solution for Rails 4 and it works well.
Use the String.split()
var array = string.split(',');

`e` in ['a', 'b', 'c'] # evaluates as False

EDIT: With the clarification, new answer:
Note that PHP arrays are vastly different from Python's, combining arrays and dicts into one confused structure. Python arrays always have indices from 0
to len(arr) - 1
, so you can check whether your index is in that range. try/catch
is a good way to do it pythonically, though.
If you're asking about the hash functionality of PHP "arrays" (Python's dict
), then my previous answer still kind of stands:
`baz` in {'foo': 17, 'bar': 19} # evaluates as False
`foo` in {'foo': 17, 'bar': 19} # evaluates as True
AlliterativeAlice's example helped me tremendously. In my case, though, the server I was talking to didn't like having single quotes around utf-8
in the content type. It failed with a generic "Server Error"
and it took hours to figure out what it didn't like:
request.ContentType = "text/xml; encoding=utf-8";
Besides these given great answers, What I have learned is that:
NEVER compare objects with == unless you intend to be comparing them by their references.

If you use proxy, you will have to edit the Nuget.config file.
In Windows 7 and 10, this file is in the path:
C:\Users\YouUser\AppData\Roaming\NuGet.
Include the setting:
<config>
<add key = "http_proxy" value = "http://Youproxy:8080" />
<add key = "http_proxy.user" value = "YouProxyUser" />
</config>
While that error message is on the screen (before the rollback begins) go to Control Panel -> Administrative Tools -> Services and see if the service is actually installed. Also check what account it is using to run as. If it's not using Local System, then double and triple check that the account it's using has rights to the program directory where MS SQL installed to.
vlado.grigorov has some good advice - the best way is to create a backgroundView, and give that a colour, setting everything else to the clearColor. Also, I think that way is the only way to correctly clear the colour (try his sample - but set 'clearColor' instead of 'yellowColor'), which is what I was trying to do.
func atributedLabel(str: String, img: UIImage)->NSMutableAttributedString
{ let iconsSize = CGRect(x: 0, y: -2, width: 16, height: 16)
let attributedString = NSMutableAttributedString()
let attachment = NSTextAttachment()
attachment.image = img
attachment.bounds = iconsSize
attributedString.append(NSAttributedString(attachment: attachment))
attributedString.append(NSAttributedString(string: str))
return attributedString
}
You can use this function to add images or small icons to the label
using include 'page1.php'
in second page is one option but it can generate warnings and errors of undefined variables.
Three methods by which you can use variables of one php file in another php file:
use session to pass variable from one page to another
method:
first you have to start the session in both the files using php command
sesssion_start();
then in first file consider you have one variable
$x='var1';now assign value of $x to a session variable using this:
$_SESSION['var']=$x;
now getting value in any another php file:
$y=$_SESSION['var'];//$y is any declared variable
using get method and getting variables on clicking a link
method
<a href="page2.php?variable1=value1&variable2=value2">clickme</a>
getting values in page2.php file by $_GET function:$x=$_GET['variable1'];//value1 be stored in $x
$y=$_GET['variable2'];//vale2 be stored in $y
if you want to pass variable value using button then u can use it by following method:
$x='value1'
<input type="submit" name='btn1' value='.$x.'/>
in second php$var=$_POST['btn1'];
Use AppKiDo to browse the documentation.
Use Accessorizer for a bunch of mundane, repetitive tasks in Xcode.
This might work. This Code dynamically appends the <script>
tag to the head
of the html file on button clicked.
const url = 'http://iknow.com/this/does/not/work/either/file.js';
export class MyAppComponent {
loadAPI: Promise<any>;
public buttonClicked() {
this.loadAPI = new Promise((resolve) => {
console.log('resolving promise...');
this.loadScript();
});
}
public loadScript() {
console.log('preparing to load...')
let node = document.createElement('script');
node.src = url;
node.type = 'text/javascript';
node.async = true;
node.charset = 'utf-8';
document.getElementsByTagName('head')[0].appendChild(node);
}
}
in this situation, you would grab the element by its id using getElementById
and then just use .src
var youtubeimgsrc = document.getElementById("youtubeimg").src;
If the cardinality of items doesn't matter (meaning: repeated elements are considered as one), then there is a way to do this without having to sort:
boolean result = new HashSet<>(listA).equals(new HashSet<>(listB));
This will create a Set
out of each List
, and then use HashSet
's equals
method which (of course) disregards ordering.
If cardinality matters, then you must confine yourself to facilities provided by List
; @jschoen's answer would be more fitting in that case.
Try this :
$obj = @{
SomeProp = "Hello"
}
Write-Host "Property Value is $($obj."SomeProp")"
seems you need to link with the obj file that implements tolayer5()
Update: your function declaration doesn't match the implementation:
void tolayer5(int AorB, struct msg msgReceived)
void tolayer5(int, char data[])
So compiler would treat them as two different functions (you are using c++). and it cannot find the implementation for the one you called in main().
Well Thanks to JeanPaul A. and rdanielmurphy. I had made my own Custom directive for limiting input field to number only. Also added the max and min input attributes. Will work in angular 7 also.
Angular
import { Directive, ElementRef, Input, HostListener } from '@angular/core';
@Directive({
selector: '[appNumberOnly]'
})
export class NumberOnlyDirective {

private regex: RegExp = new RegExp(/^[0-9]+(\.[0-9]*){0,1}$/g);
// Allow key codes for special events. Reflect :
// Backspace, tab, end, home
private specialKeys: Array<string> = ['Backspace', 'Tab', 'End', 'Home'];
constructor(private el: ElementRef) { }
@Input() maxlength: number;
@Input() min: number;
@Input() max: number;
@HostListener('keydown', ['$event'])
onKeyDown(event: KeyboardEvent) {
// Allow Backspace, tab, end, and home keys
if (this.specialKeys.indexOf(event.key) !== -1) {
return;
}
// Do not use event.keycode this is deprecated.
// See: https://developer.mozilla.org/en-US/docs/Web/API/KeyboardEvent/keyCode
const current: string = this.el.nativeElement.value;
// We need this because the current value on the DOM element
// is not yet updated with the value from this event
const next: string = current.concat(event.key);
if (next && !String(next).match(this.regex) || (this.maxlength && next.length > this.maxlength) ||
(this.min && +next < this.min) ||
(this.max && +next >= this.max)) {
event.preventDefault();
}
}
@HostListener('paste', ['$event']) onPaste(event) {
// Don't allow pasted text that contains non-numerics
const pastedText = (event.originalEvent || event).clipboardData.getData('text/plain');
if (pastedText) {
const regEx = new RegExp('^[0-9]*$');
if (!regEx.test(pastedText) || (this.maxlength && pastedText.length > this.maxlength) ||
(this.min && +pastedText < this.min) ||
(this.max && +pastedText >= this.max)) {
event.preventDefault();
}
}
}
}

What are you trying to do with reflection?
You can use the Boost type traits and typeof libraries as a limited form of compile-time reflection. That is, you can inspect and modify the basic properties of a type passed to a template.
You can try something like:
var str = "a,d,k";
str.replace(/,/g, "");
Use the getResourceAsStream()
method on the ServletContext object, e.g.
servletContext.getResourceAsStream("/WEB-INF/myfile");
How you get a reference to the ServletContext depends on your application... do you want to do it from a Servlet or from a JSP?
EDITED: If you're inside a Servlet object, then call getServletContext()
. If you're in JSP, use the predefined variable application
.
To get a position of an element in a vector knowing an iterator pointing to the element, simply subtract v.begin()
from the iterator:
ptrdiff_t pos = find(Names.begin(), Names.end(), old_name_) - Names.begin();
Now you need to check pos
against Names.size()
to see if it is out of bounds or not:
if(pos >= Names.size()) {
//old_name_ not found
}
vector iterators behave in ways similar to array pointers; most of what you know about pointer arithmetic can be applied to vector iterators as well.
Starting with C++11 you can use std::distance
in place of subtraction for both iterators and pointers:
ptrdiff_t pos = distance(Names.begin(), find(Names.begin(), Names.end(), old_name_));
Running gem update --system

protocol. Terminal command:

SOLVED:
The above did not help. Then I simply installed sklearn from within Jypyter-lab, even though sklearn 0.0 shows in 'pip list':
!pip install sklearn
import sklearn
What I learned later is that pip installs, in my case, packages in a different folder than Jupyter. This can be seen by executing:
import sys
print(sys.path)
Once from within Jupyter_lab notebook, and once from the command line using 'py notebook.py'.
In my case Jupyter list of paths where subfolders of 'anaconda' whereas Python list where subfolders of c:\users[username]...
I've found that the above solution will not work if you have to deal with control characters like 02
(STX) or 03
(ETX), anything under 10
will be read as a single digit and throw off everything after. I ran into this problem trying to parse through serial communications. So, I first took the hex string received and put it in a buffer object then converted the hex string into an array of the strings like so:
buf = Buffer.from(data, 'hex');
l = Buffer.byteLength(buf,'hex');
for (i=0; i<l; i++){
char = buf.toString('hex', i, i+1);
msgArray.push(char);
}
Then .join it
message = msgArray.join('');
then I created a hexToAscii
function just like in @Delan Azabani's answer above...
function hexToAscii(str){
hexString = str;
strOut = '';
for (x = 0; x < hexString.length; x += 2) {
strOut += String.fromCharCode(parseInt(hexString.substr(x, 2), 16));
}
return strOut;
}
then called the hexToAscii
function on 'message'
message = hexToAscii(message);
This approach also allowed me to iterate through the array and slice into the different parts of the transmission using the control characters so I could then deal with only the part of the data I wanted. Hope this helps someone else!
To read json response use json.loads()
. Here is the sample.
import json
import urllib
import urllib2
post_params = {
'foo' : bar
}
params = urllib.urlencode(post_params)
response = urllib2.urlopen(url, params)
json_response = json.loads(response.read())

python -m http.server [<portNo>]
Because I am using Python 3 the module SimpleHTTPServer
has been replaced by http.server
, at least in Windows.
REST is just a software architecture style for exposing resources.
A typical REST call to return information about customer 34456 could look like:
http://example.com/customer/34456
Have a look at the IBM tutorial for REST web services
I came across a similar situation after publishing a ClickOnce application, and one of my colleagues on a different domain reported that it fails to launch.
To find out what was going on, I added a try catch statement inside the MainWindow method as @BradleyDotNET mentioned in one comment on the original post, and then published again.
public MainWindow()
{
try
{
InitializeComponent();
}
catch (Exception exc)
{
MessageBox.Show(exc.ToString());
}
}
Then my colleague reported to me the exception detail, and it was a missing reference of a third party framework dll file.
Added the reference and problem solved.
I know this post is old but I ran into this same issue and finally figured out a solution to determine which column was causing the problem and report it back as needed. I determined that colid
returned in the SqlException is not zero based so you need to subtract 1 from it to get the value. After that it is used as the index of the _sortedColumnMappings
ArrayList of the SqlBulkCopy instance not the index of the column mappings that were added to the SqlBulkCopy instance. One thing to note is that SqlBulkCopy will stop on the first error received so this may not be the only issue but at least helps to figure it out.
try
{
bulkCopy.WriteToServer(importTable);
sqlTran.Commit();
}
catch (SqlException ex)
{
if (ex.Message.Contains("Received an invalid column length from the bcp client for colid"))
{
string pattern = @"\d+";
Match match = Regex.Match(ex.Message.ToString(), pattern);
var index = Convert.ToInt32(match.Value) -1;
FieldInfo fi = typeof(SqlBulkCopy).GetField("_sortedColumnMappings", BindingFlags.NonPublic | BindingFlags.Instance);
var sortedColumns = fi.GetValue(bulkCopy);
var items = (Object[])sortedColumns.GetType().GetField("_items", BindingFlags.NonPublic | BindingFlags.Instance).GetValue(sortedColumns);
FieldInfo itemdata = items[index].GetType().GetField("_metadata", BindingFlags.NonPublic | BindingFlags.Instance);
var metadata = itemdata.GetValue(items[index]);
var column = metadata.GetType().GetField("column", BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Instance).GetValue(metadata);
var length = metadata.GetType().GetField("length", BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Instance).GetValue(metadata);
throw new DataFormatException(String.Format("Column: {0} contains data with a length greater than: {1}", column, length));
}
throw;
}
To the C language, '\0'
means exactly the same thing as the integer constant 0
(same value zero, same type int
).
To someone reading the code, writing '\0'
suggests that you're planning to use this particular zero as a character.
According to the book PHP and MySQL for Dynamic Web Sites (4th edition)
Example:
$r = mysqli_query($dbc, $q);
For simple queries like INSERT, UPDATE, DELETE, etc. (which do not return records), the $r
variable—short for result—will be either TRUE or FALSE, depending upon whether the query executed successfully.
Keep in mind that “executed successfully” means that it ran without error; it doesn’t mean that the query’s execution necessarily had the desired result; you’ll need to test for that.
Then how to test?
While the mysqli_num_rows()
function will return the number of rows generated by a SELECT query, mysqli_affected_rows()
returns the number of rows affected by an INSERT, UPDATE, or DELETE query. It’s used like so:
$num = mysqli_affected_rows($dbc);
Unlike mysqli_num_rows()
, the one argument the function takes is the database connection ($dbc), not the results of the previous query ($r).
THIS IS A VERY SIMPLE PROBLEM
Here is the best method for solve this problem.
Step 1 : Login to your cPanel (http://website.com/cpanel OR http://cpanel.website.com).
Step 2 : SOFTWARE -> Select PHP Version
Step 3 : Change Your Current PHP version : 5.6
Step 3 : HIT 'Set as current' [ ENJOY ]
The same error occurs also when doing SELECT DISTINCT ..., <CLOB_column>, ...
.
If this CLOB column contains values shorter than limit for VARCHAR2 in all the applicable rows you may use to_char(<CLOB_column>)
or concatenate results of multiple calls to DBMS_LOB.SUBSTR(<CLOB_column>, ...)
.
UPDATED
After few research, best solution was to use that info another stackoverflow thread to avoid ctrl+z input and also from the scree output.
So, instead of php -a
you should use call "php.exe" -f NAMED_SCRIPT.php
OLD Readline not possible under Windows, so none of existent php shells written in php will work. But there's a workaround using -a interactive mode.
2 commmon problems here. You cannot see result until executes CTRL Z command to indicate the final of code/file like EOF. When you do, result in most cases is printed result and fast closed window. Anyway, you will be returned to cmd not the -a interactive mode.
Save this content into a .bat file, and define your PHP PATH into Windows variables, or modify php.exe to "full path to exe" instead:
::
:: PHP Shell launch wrapper
::
@ECHO off
call "php.exe" -a
echo.
echo.
call "PHP Shell.bat"
This is a simple Batch launching -a mode of php.exe. When it launchs php, stop script even no pause is wrote because is "into" the interactive waiting for input. When you hit CTRL Z, gets the SIGSTEP (next step) not the SIGSTOP (close, CTRL+C usually), then read the next intruction, wich is a recursive call to .bat itself. Because you're always into PHP -a mode, no exit command. You must use CTRL+C or hit the exit cross with mouse. (No alt+f4)
You can also use "Bat to Exe" converter to easy use.
Why not use Model.update? After all you're not using the found user for anything else than to update it's properties:
User.update({username: oldUsername}, {
username: newUser.username,
password: newUser.password,
rights: newUser.rights
}, function(err, numberAffected, rawResponse) {
//handle it
})
What Anthony says is absolutely correct, but I'd like to add that your experience will likely show a lot better performance and efficiency (due not to fpm
-vs-fcgi
but more to the implementation of your httpd
).
For example, I had a quad-core machine running lighttpd
+ fcgi
humming along nicely. I upgraded to a 16-core machine to cope with growth, and two things exploded: RAM usage, and segfaults. I found myself restarting lighttpd
every 30 minutes to keep the website up.
I switched to php-fpm and nginx, and RAM usage dropped from >20GB to 2GB. Segfaults disappeared as well. After doing some research, I learned that lighttpd and fcgi don't get along well on multi-core machines under load, and also have memory leak issues in certain instances.
Is this due to php-fpm
being better than fcgi
? Not entirely, but how you hook into php-fpm
seems to be a whole heckuva lot more efficient than how you serve via fcgi
.
Regarding you question about betterhost and such, see host; basically every IP address is a host.
I suggest you start reading-up from host and only than go on to localhost (which is a type of host)
A Python 2/3 portable solution
To calculate a checksum (md5, sha1, etc.), you must open the file in binary mode, because you'll sum bytes values:
To be py27/py3 portable, you ought to use the io
packages, like this:
import hashlib
import io
def md5sum(src):
md5 = hashlib.md5()
with io.open(src, mode="rb") as fd:
content = fd.read()
md5.update(content)
return md5
If your files are big, you may prefer to read the file by chunks to avoid storing the whole file content in memory:
def md5sum(src, length=io.DEFAULT_BUFFER_SIZE):
md5 = hashlib.md5()
with io.open(src, mode="rb") as fd:
for chunk in iter(lambda: fd.read(length), b''):
md5.update(chunk)
return md5
The trick here is to use the iter()
function with a sentinel (the empty string).
The iterator created in this case will call o [the lambda function] with no arguments for each call to its
next()
method; if the value returned is equal to sentinel,StopIteration
will be raised, otherwise the value will be returned.
If your files are really big, you may also need to display progress information. You can do that by calling a callback function which prints or logs the amount of calculated bytes:
def md5sum(src, callback, length=io.DEFAULT_BUFFER_SIZE):
calculated = 0
md5 = hashlib.md5()
with io.open(src, mode="rb") as fd:
for chunk in iter(lambda: fd.read(length), b''):
md5.update(chunk)
calculated += len(chunk)
callback(calculated)
return md5
:first-child
selects the first h1
if and only if it is the first child of its parent element. In your example, the ul
is the first child of the div
.
The name of the pseudo-class is somewhat misleading, but it's explained pretty clearly here in the spec.
jQuery's :first
selector gives you what you're looking for. You can do this:
$('.detail_container h1:first').css("color", "blue");
I'm now using RxJS 5.5.7 in an Angular application and using finalize
operator has a weird behavior for my use case since is fired before success or error callbacks.
Simple example:
// Simulate an AJAX callback...
of(null)
.pipe(
delay(2000),
finalize(() => {
// Do some work after complete...
console.log('Finalize method executed before "Data available" (or error thrown)');
})
)
.subscribe(
response => {
console.log('Data available.');
},
err => {
console.error(err);
}
);
I have had to use the add
medhod in the subscription to accomplish what I want. Basically a finally
callback after the success or error callbacks are done. Like a try..catch..finally
block or Promise.finally
method.
Simple example:
// Simulate an AJAX callback...
of(null)
.pipe(
delay(2000)
)
.subscribe(
response => {
console.log('Data available.');
},
err => {
console.error(err);
}
);
.add(() => {
// Do some work after complete...
console.log('At this point the success or error callbacks has been completed.');
});
Not even that complicated and no imports required in Java 7:
The renameTo( )
method changes the name of a file:
public boolean renameTo( File destination)
For example, to change the name of the file src.txt
in the current working directory to dst.txt
, you would write:
File src = new File(" src.txt"); File dst = new File(" dst.txt"); src.renameTo( dst);
That's it.

Just one thing to add to this (although I do think you have already had your question answered by others). In the interests of extensibility (since we all know it will happen at some point) you may want to check out the Composite Pattern This is ideal for working with "Tree-Like Structures"..
Like I said, I know you are only expecting one sub-level, but this could really be useful for you if you later need to extend ^_^
In v4 change the SASS variable:
$font-size-base: 1rem !default;
Turning my linux environment into a clean complete UTF-8 environment made the trick for me. Try the following in your command line:
export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8
export LANGUAGE=en_US.UTF-8
just run the following command in the node project
npm install
its worked for me
You want to use the csv module that is part of the python language and you should use Django's get_or_create method
with open(path) as f:
reader = csv.reader(f)
for row in reader:
_, created = Teacher.objects.get_or_create(
first_name=row[0],
last_name=row[1],
middle_name=row[2],
)
# creates a tuple of the new object or
# current object and a boolean of if it was created
In my example the model teacher has three attributes first_name, last_name and middle_name.
Django documentation of get_or_create method
Well, a for or while loop differs from a do while loop. A do while executes the statements atleast once, even if the condition turns out to be false.
The for loop you specified is absolutely correct.
Although i will do all the loops for you once again.
int sum = 0;
// for loop
for (int i = 1; i<= 100; i++){
sum = sum + i;
}
System.out.println(sum);
// while loop
sum = 0;
int j = 1;
while(j<=100){
sum = sum + j;
j++;
}
System.out.println(sum);
// do while loop
sum = 0;
j = 1;
do{
sum = sum + j;
j++;
}
while(j<=100);
System.out.println(sum);
In the last case condition j <= 100 is because, even if the condition of do while turns false, it will still execute once but that doesn't matter in this case as the condition turns true, so it continues to loop just like any other loop statement.
If you need the line number for more than just the formatted stack trace you get from Exception.StackTrace, you can use the StackTrace class:
try
{
throw new Exception();
}
catch (Exception ex)
{
// Get stack trace for the exception with source file information
var st = new StackTrace(ex, true);
// Get the top stack frame
var frame = st.GetFrame(0);
// Get the line number from the stack frame
var line = frame.GetFileLineNumber();
}
Note that this will only work if there is a pdb file available for the assembly.
For angular 8 and Firebase 6 you can use the option id field
getAllDocs() {
const ref = this.db.collection('items');
return ref.valueChanges({idField: 'customIdName'});
}
this adds the Id of the document on the object with a specified key (customIdName)
If you are using .NET 3.5+ you could use LINQ (Language INtegrated Query).
test = test.Where(x => !string.IsNullOrEmpty(x)).ToArray();
[function.fopen]: failed to open stream
If you have access to your php.ini file, try enabling Fopen. Find the respective line and set it to be "on": & if in wp e.g localhost/wordpress/function.fopen in the php.ini :
allow_url_fopen = off
should bee this
allow_url_fopen = On
And add this line below it:
allow_url_include = off
should bee this
allow_url_include = on
rails destroy controller lalala
rails destroy model yadayada
rails destroy scaffold hohoho
Rails 3.2 adds a new d
shortcut to the command, so now you can write:
rails d controller lalala
rails d model yadayada
rails d scaffold hohoho
You can pass params directly to $http.get()
The following works fine
$http.get(user.details_path, {
params: { user_id: user.id }
});
Say you have a class named EmployeeService that you want to test and that has one dependency on an interface named EmployeeDao:
public class EmployeeService{
private EmployeeDao dao;
public EmployeeService(Dao dao){this.dao = dao;}
public String getEmployeeName(int id){
Employee emp = bar.goToDatabaseAndBringTheEmployeeWithId(id);
return emp != null?emp.getFullName:null;
}
//Further state and behavior
}
public interface EmployeeDao{
Employee goToDatabaseAndBringTheEmployeeWithId(int id);
}
Inside your test class:
public class EmployeeServiceTest{
EmployeeService service;
EmployeeDao mockDao = Mockito.mock(EmployeeDao.class);//Line 3
@Before
public void setUp(){
service = new EmployeeService(mockDao);
}
//Tests
//....
}
In the above test class in line 3, we say to the mocking framework (in this case Mockito) "Hey, Mockito, craft me an object that has the EmployeeDao functionality." The framework is going to create an object that has the method goToDatabaseAndBringTheEmployeeWithId
but actually with no body. It's your job to instruct that mock what to do. This is a mock.
But you could also create a class that implements the EmployeeDao interface and use it in the test class instead:
public EmployeeDaoStub implements EmployeeDao{
public Employee goToDatabaseAndBringTheEmployeeWithId(int id){
//No trip to DB, just returning a dummy Employee object
return new Employee("John","Woo","123 Lincoln str");
}
}
Inside your test class this time using stub instead of a mock:
public class EmployeeServiceTest{
EmployeeService service;
EmployeeDao daoStub = new EmployeeDaoStub();//Line 3
@Before
public void setUp(){
service = new EmployeeService(daoStub);
}
//Tests
//....
}
So to wrap it all, stubs are the classes that you create(or somebody else does) specifically to imitate some dependency just for the sake of having the desired state. Yes, as all the other people state, it's mostly about a state Whereas mocks are typically created by a mocking framework and you have no idea what its guts look like. But with stubs you know what class you're going to get: It's the one you created.
Oh, btw, if your dependency is a class rather than an interface, you can just extend that class to create your stub.
function trbl(e, relative) {
var r = $(e).get(0).getBoundingClientRect(); relative = $(relative);
return {
t : r.top + relative['scrollTop'] (),
r : r.right + relative['scrollLeft'](),
b : r.bottom + relative['scrollTop'] (),
l : r.left + relative['scrollLeft']()
}
}
// Example
trbl(e, window);
Example from this gist
func readLine(path string) {
inFile, err := os.Open(path)
if err != nil {
fmt.Println(err.Error() + `: ` + path)
return
}
defer inFile.Close()
scanner := bufio.NewScanner(inFile)
for scanner.Scan() {
fmt.Println(scanner.Text()) // the line
}
}
but this gives an error when there is a line that larger than Scanner's buffer.
When that happened, what I do is use reader := bufio.NewReader(inFile)
create and concat my own buffer either using ch, err := reader.ReadByte()
or len, err := reader.Read(myBuffer)
Another way that I use (replace os.Stdin with file like above), this one concats when lines are long (isPrefix) and ignores empty lines:
func readLines() []string {
r := bufio.NewReader(os.Stdin)
bytes := []byte{}
lines := []string{}
for {
line, isPrefix, err := r.ReadLine()
if err != nil {
break
}
bytes = append(bytes, line...)
if !isPrefix {
str := strings.TrimSpace(string(bytes))
if len(str) > 0 {
lines = append(lines, str)
bytes = []byte{}
}
}
}
if len(bytes) > 0 {
lines = append(lines, string(bytes))
}
return lines
}
IMHO, RAD = LINQ, RUP = Stored Procs. I worked for a large Fortune 500 company for many years, at many levels including management, and frankly, I would never hire RUP developers to do RAD development. They are so siloed that they very limited knowledge of what to do at other levels of the process. With a siloed environment, it makes sense to give DBAs control over the data through very specific entry points, because others frankly don't know the best ways to accomplish data management.
But large enterprises move painfully slow in the development arena, and this is extremely costly. There are times when you need to move faster to save both time and money, and LINQ provides that and more in spades.
Sometimes I think that DBAs are biased against LINQ because they feel it threatens their job security. But that's the nature of the beast, ladies and gentlemen.
To find which library is being used you could run
$ /sbin/ldconfig -p | grep stdc++
libstdc++.so.6 (libc6) => /usr/lib/libstdc++.so.6
The list of compatible versions for libstdc++ version 3.4.0 and above is provided by
$ strings /usr/lib/libstdc++.so.6 | grep LIBCXX
GLIBCXX_3.4
GLIBCXX_3.4.1
GLIBCXX_3.4.2
...
For earlier versions the symbol GLIBCPP
is defined.
The date stamp of the library is defined in a macro __GLIBCXX__
or __GLIBCPP__
depending on the version:
// libdatestamp.cxx
#include <cstdio>
int main(int argc, char* argv[]){
#ifdef __GLIBCPP__
std::printf("GLIBCPP: %d\n",__GLIBCPP__);
#endif
#ifdef __GLIBCXX__

WHERE O.GKZ = '06440004'
Without a doubt, the simplest method uses an invisible FORM element in HTML specifying the desired REST method. Then the arguments can be inserted into input type=hidden
value fields using JavaScript and the form can be submitted from the button click event listener or onclick event using one line of JavaScript. Here is an example that assumes the REST API is in file REST.php:
<body>
<h2>REST-test</h2>
<input type=button onclick="document.getElementById('a').submit();"
value="Do It">
<form id=a action="REST.php" method=post>
<input type=hidden name="arg" value="val">
</form>
</body>
Note that this example will replace the page with the output from page REST.php. I'm not sure how to modify this if you wish the API to be called with no visible effect on the current page. But it's certainly simple.
Not a general answer, but may be useful for the specific case where you are happy with the default python 2 encoding, but want to specify utf-8 for python 3:
if sys.version_info.major > 2:
do_open = lambda filename: open(filename, encoding='utf-8')
else:
do_open = lambda filename: open(filename)
with do_open(filename) as file:
pass
Install Anaconda for Python 3.5 - Can install from here for 64 bit windows
Then install TensorFlow from here
(I tried previously with Anaconda for Python 3.6 but failed even after creating Conda env for Python3.5)
Additionally if you want to run a Jupyter Notebook and use TensorFlow in it. Use following steps.
Change to TensorFlow env:
C: > activate tensorflow
(tensorflow) C: > pip install jupyter notebook
Once installed, you can launch Jupyter Notebook and test
(tensorflow) C: > jupyter notebook
You do not need any client side code if doing this is ASP.NET. The example below is a boostrap input box with a search button with an fontawesome icon.
You will see that in place of using a regular < div > tag with a class of "input-group" I have used a asp:Panel. The DefaultButton property set to the id of my button, does the trick.
In example below, after typing something in the input textbox, you just hit enter and that will result in a submit.
<asp:Panel DefaultButton="btnblogsearch" runat="server" CssClass="input-group blogsearch">
<asp:TextBox ID="txtSearchWords" CssClass="form-control" runat="server" Width="100%" Placeholder="Search for..."></asp:TextBox>
<span class="input-group-btn">
<asp:LinkButton ID="btnblogsearch" runat="server" CssClass="btn btn-default"><i class="fa fa-search"></i></asp:LinkButton>
</span></asp:Panel>
Actually, I'm quite curious why nobody spoke about the UML specifications. A rule of thumb is that if you have an aggregation, then you should use references. But if it is a composition, then the coupling is stronger, and you should use embedded documents.
And you will quickly understand why it is logical. If an object can exist independently of the parent, then you will want to access it even if the parent doesn't exist. As you just can't embed it in a non-existing parent, you have to make it live in it's own data structure. And if a parent exist, just link them together by adding a ref of the object in the parent.
Don't really know what is the difference between the two relationships ? Here is a link explaining them: Aggregation vs Composition in UML
Use the "form" attribute, if you want to save your markup:
<form method="GET" id="my_form"></form>
<table>
<tr>
<td>
<input type="text" name="company" form="my_form" />
<button type="button" form="my_form">ok</button>
</td>
</tr>
</table>
(*Form fields outside of the < form > tag)
Elaborating on this answer and this answer.
Above answers point out the problem of many of the solutions here which don't iterate by code point value -- they would have trouble with any surrogate chars. The java docs also outline the issue here (see "Unicode Character Representations"). Anyhow, here's some code that uses some actual surrogate chars from the supplementary Unicode set, and converts them back to a String. Note that .toChars() returns an array of chars: if you're dealing with surrogates, you'll necessarily have two chars. This code should work for any Unicode character.
String supplementary = "Some Supplementary: ";
supplementary.codePoints().forEach(cp ->
System.out.print(new String(Character.toChars(cp))));
Use jQuery's IsNumeric method.
http://api.jquery.com/jQuery.isNumeric/
if ($.isNumeric(id)) {
//it's numeric
}
CORRECTION: that would not ensure an integer. This would:
if ( (id+"").match(/^\d+$/) ) {
//it's all digits
}
That, of course, doesn't use jQuery, but I assume jQuery isn't actually mandatory as long as the solution works
I had to reinstall my postgres, great instructions outlined here: https://medium.com/@zowoodward/effectively-uninstall-and-reinstall-psql-with-homebrew-on-osx-fabbc45c5d9d

This approach will clobber all of your local data so please back up your data if needed.
Graphically, the cron syntax for Quarz is (source):
+-------------------- second (0 - 59)
| +----------------- minute (0 - 59)
| | +-------------- hour (0 - 23)
| | | +----------- day of month (1 - 31)
| | | | +-------- month (1 - 12)
| | | | | +----- day of week (0 - 6) (Sunday=0 or 7)
| | | | | | +-- year [optional]
| | | | | | |
* * * * * * * command to be executed
So if you want to run a command every 30 minutes you can say either of these:
0 0/30 * * * * ?
0 0,30 * * * * ?
You can check crontab expressions using either of these:
Use minimal-json which is very fast and easy to use. You can parse from String obj and Stream.
Sample data:
{
"order": 4711,
"items": [
{
"name": "NE555 Timer IC",
"cat-id": "645723",
"quantity": 10,
},
{
"name": "LM358N OpAmp IC",
"cat-id": "764525",
"quantity": 2
}
]
}
Parsing:
JsonObject object = Json.parse(input).asObject();
int orders = object.get("order").asInt();
JsonArray items = object.get("items").asArray();
Creating JSON:
JsonObject user = Json.object().add("name", "Sakib").add("age", 23);
Maven:
<dependency>
<groupId>com.eclipsesource.minimal-json</groupId>

<version>0.9.4</version>
</dependency>
If by "hex data" you mean a string of the form
s = "6a48f82d8e828ce82b82"
you can use
i = int(s, 16)
to convert it to an integer and
str(i)
to convert it to a decimal string.
recreate()
(as mentioned by TPReal) will only restart current activity, but the previous activities will still be in back stack and theme will not be applied to them.
So, another solution for this problem is to recreate the task stack completely, like this:
TaskStackBuilder.create(getActivity())
.addNextIntent(new Intent(getActivity(), MainActivity.class))
.addNextIntent(getActivity().getIntent())
.startActivities();
EDIT:
Just put the code above after you perform changing of theme on the UI or somewhere else. All your activities should have method setTheme()
called before onCreate()
, probably in some parent activity. It is also a normal approach to store the theme chosen in SharedPreferences
, read it and then set using setTheme()
method.
rake routes | grep <specific resource name>
displays resource specific routes, if it is a pretty long list of routes.
I think what you want is to have access to the request context, see RequestContext.

if section == 0
{
// Note CGFloat.min for swift
// For Objective-c CGFLOAT_MIN
let headerView = UIView.init(frame: CGRectMake(0.0, 0.0, self.myShaadiTableview.bounds.size.width, CGFloat.min))
return headerView
}
else
{
// Construct your other headers here
}
For those looking a more modern approach, you can use the fetch API
. The following example shows how to download a PDF
file. It is easily done with the following code.
fetch(url, {
body: JSON.stringify(data),
method: 'POST',
headers: {
'Content-Type': 'application/json; charset=utf-8'
},
})
.then(response => response.blob())
.then(response => {
const blob = new Blob([response], {type: 'application/pdf'});
const downloadUrl = URL.createObjectURL(blob);
const a = document.createElement("a");
a.href = downloadUrl;
a.download = "file.pdf";
document.body.appendChild(a);
a.click();
})
I believe this approach to be much easier to understand than other XMLHttpRequest
solutions. Also, it has a similar syntax to the jQuery
approach, without the need to add any additional libraries.
Of course, I would advise checking to which browser you are developing, since this new approach won't work on IE. You can find the full browser compatibility list on the following [link][1].
Important: In this example I am sending a JSON request to a server listening on the given url
. This url
must be set, on my example I am assuming you know this part. Also, consider the headers needed for your request to work. Since I am sending a JSON, I must add the Content-Type
header and set it to application/json; charset=utf-8
, as to let the server know the type of request it will receive.

I was also having the same problem, but I set the height value in my CSS to auto and that fixed my problem. Also, don't forget to do the display property.
#image {
height: auto;
width: auto;
max-height: 550px;
max-width: 1200px;
margin-left: auto;
margin-right: auto;
display: block;
}
Hello I was searching for a solution to reverse sorting a two dimensional numpy array, and I couldn't find anything that worked, but I think I have stumbled on a solution which I am uploading just in case anyone is in the same boat.
x=np.sort(array)
y=np.fliplr(x)
np.sort sorts ascending which is not what you want, but the command fliplr flips the rows left to right! Seems to work!
Hope it helps you out!
I guess it's similar to the suggest about -np.sort(-a) above but I was put off going for that by comment that it doesn't always work. Perhaps my solution won't always work either however I have tested it with a few arrays and seems to be OK.
A solution with Gson:
Gson gson = new Gson();
JsonElement jsonElement = gson.toJsonTree(map);
MyPojo pojo = gson.fromJson(jsonElement, MyPojo.class);
Same question as @Dan - why not StringReader ?
If it has to be InputStreamReader, then:
String charset = ...; // your charset
byte[] bytes = string.getBytes(charset);
ByteArrayInputStream bais = new ByteArrayInputStream(bytes);
InputStreamReader isr = new InputStreamReader(bais);
An other service that could occupied the port 80 is BranchCache
services.msc
showing it as "BranchCache"
or use the net
command to stop the service like
net stop PeerDistSvc
Update:
PeerDistSvc is a service behind svhost.exe, to view svchost services type
tasklist /svc /fi "imagename eq svchost.exe"
Call decode()
on a bytes
instance to get the text which it encodes.
str = bytes.decode()
Use the builtin type
function to get the type, then you can use the __module__
property to find out where it was defined:
>>> import numpy as np
a = np.array([1, 2, 3])
>>> type(a)
<type 'numpy.ndarray'>
>>> type(a).__module__
'numpy'
>>> type(a).__module__ == np.__name__

No need for Javascript, you just have to add a target="_blank"
attribute in your form tag.
<form target="_blank" action="http://example.com"
method="post" id="mc-embedded-subscribe-form"
name="mc-embedded-subscribe-form" class="validate"
>
You can change the aspectRatio
according to your needs:
options:{
aspectRatio:4 //(width/height)
}
Have a look at XPCOM, there might be something that you can use if Firefox 3 is used by a client.
Well, the dead-simple way to do it is to make a list of all the numbers you're interested in:
numbers = ["zero", "one", "two", "three", "four", "five", ...
"ninety-eight", "ninety-nine"]
(The ... indicates where you'd type the text representations of other numbers. No, Python isn't going to magically fill that in for you, you'd have to type all of them to use that technique.)
And then to print the number, just print numbers[i]
. Easy peasy.
Of course, that list is a lot of typing, so you might wonder about an easy way to generate it. English unfortunately has a lot of irregularities so you'd have to manually put in the first twenty (0-19), but you can use regularities to generate the rest up to 99. (You can also generate some of the teens, but only some of them, so it seems easiest to just type them in.)
numbers = "zero one two three four five six seven eight nine".split()
numbers.extend("ten eleven twelve thirteen fourteen fifteen sixteen".split())
numbers.extend("seventeen eighteen nineteen".split())
numbers.extend(tens if ones == "zero" else (tens + "-" + ones)
for tens in "twenty thirty forty fifty sixty seventy eighty ninety".split()
for ones in numbers[0:10])
print numbers[42] # "forty-two"
Another approach is to write a function that puts together the correct string each time. Again you'll have to hard-code the first twenty numbers, but after that you can easily generate them from scratch as needed. This uses a little less memory (a lot less once you start working with larger numbers).
$cfg['Servers'][$i]['AllowNoPassword'] = TRUE;
yes the above answer is correct, but it's not secure, you can login root user directlyinto phpMyAdmin
.
If you want to create new user with password and give grant permission, execute the below command in MySQL on terminal, Login into your server on terminal,
# mysql
mysql> GRANT ALL PRIVILEGES ON *.* TO 'user-name'@'%' IDENTIFIED BY 'password' REQUIRE NONE WITH GRANT OPTION MAX_QUERIES_PER_HOUR 0 MAX_CONNECTIONS_PER_HOUR 0 MAX_UPDATES_PER_HOUR 0 MAX_USER_CONNECTIONS 0;
you have to write only one line in maps_activity.xml
map:cameraZoom="13"
I hope this will solve your problem...
You can append the values in the query string for the next page to see and process. You can wrap them inside the link tags:
<a href="your_page.php?var1=value1&var2=value2">
You separate each of those values with the &
sign.
Or you can create this on a button click like this:
<input type="button" onclick="document.location.href = 'your_page.php?var1=value1&var2=value2';">
If you just put '/' in the href it will reload the current window.
<a href="/">
Reload the page
</a>

Word starts page numbering over for each new section by default.
I do it slightly differently than the post above that goes through the ribbon menus, but in both methods you have to go through the document to each section's beginning.
My method:
Format Page Numbers
Continue from Previous Section
radio button under Page numbering
I find this right-click method to be a little faster. Also, usually if I insert the page numbers first before I start making any new sections, this problem doesn't happen in the first place.
You need to fix the spacing and quotes:
export PATH ="/Users/Dz/anaconda/bin:$PATH"
Instead use
export PATH="/Users/Dz/anaconda/bin":$PATH
In angular7, I simply used
let routesObject = require('./routes.json');
My routes.json file looks like this
{
"routeEmployeeList": "employee-list",
"routeEmployeeDetail": "employee/:id"
}
You access json items using
routesObject.routeEmployeeList
Personally, I just use Cygwin. Which allows you to use many common *nix commands in Windows. SSH being one of them.
DateTime.Now
returns a DateTime
value that consists of the local date and time of the computer where the code is running. It has DateTimeKind.Local
assigned to its Kind
property. It is equivalent to calling any of the following:
DateTime.UtcNow.ToLocalTime()
DateTimeOffset.UtcNow.LocalDateTime
DateTimeOffset.Now.LocalDateTime
TimeZoneInfo.ConvertTime(DateTime.UtcNow, TimeZoneInfo.Local)
TimeZoneInfo.ConvertTimeFromUtc(DateTime.UtcNow, TimeZoneInfo.Local)
DateTime.Today
returns a DateTime
value that has the same year, month, and day components as any of the above expressions, but with the time components set to zero. It also has DateTimeKind.Local
in its Kind
property. It is equivalent to any of the following:
DateTime.Now.Date
DateTime.UtcNow.ToLocalTime().Date
DateTimeOffset.UtcNow.LocalDateTime.Date
DateTimeOffset.Now.LocalDateTime.Date
TimeZoneInfo.ConvertTime(DateTime.UtcNow, TimeZoneInfo.Local).Date
TimeZoneInfo.ConvertTimeFromUtc(DateTime.UtcNow, TimeZoneInfo.Local).Date
Note that internally, the system clock is in terms of UTC, so when you call DateTime.Now
it first gets the UTC time (via the GetSystemTimeAsFileTime
function in the Win32 API) and then it converts the value to the local time zone. (Therefore DateTime.Now.ToUniversalTime()
is more expensive than DateTime.UtcNow
.)
Also note that DateTimeOffset.Now.DateTime
will have similar values to DateTime.Now
, but it will have DateTimeKind.Unspecified
rather than DateTimeKind.Local
- which could lead to other errors depending on what you do with it.
So, the simple answer is that DateTime.Today
is equivalent to DateTime.Now.Date
.
But IMHO - You shouldn't use either one of these, or any of the above equivalents.
When you ask for DateTime.Now
, you are asking for the value of the local calendar clock of the computer that the code is running on. But what you get back does not have any information about that clock! The best that you get is that DateTime.Now.Kind == DateTimeKind.Local
. But whose local is it? That information gets lost as soon as you do anything with the value, such as store it in a database, display it on screen, or transmit it using a web service.
If your local time zone follows any daylight savings rules, you do not get that information back from DateTime.Now
. In ambiguous times, such as during a "fall-back" transition, you won't know which of the two possible moments correspond to the value you retrieved with DateTime.Now
. For example, say your system time zone is set to Mountain Time (US & Canada)
and you ask for DateTime.Now
in the early hours of November 3rd, 2013. What does the result 2013-11-03 01:00:00
mean? There are two moments of instantaneous time represented by this same calendar datetime. If I were to send this value to someone else, they would have no idea which one I meant. Especially if they are in a time zone where the rules are different.
The best thing you could do would be to use DateTimeOffset
instead:
// This will always be unambiguous.
DateTimeOffset now = DateTimeOffset.Now;
Now for the same scenario I described above, I get the value 2013-11-03 01:00:00 -0600
before the transition, or 2013-11-03 01:00:00 -0700
after the transition. Anyone looking at these values can tell what I meant.
I wrote a blog post on this very subject. Please read - The Case Against DateTime.Now.
Also, there are some places in this world (such as Brazil) where the "spring-forward" transition happens exactly at Midnight. The clocks go from 23:59 to 01:00. This means that the value you get for DateTime.Today
on that date, does not exist! Even if you use DateTimeOffset.Now.Date
, you are getting the same result, and you still have this problem. It is because traditionally, there has been no such thing as a Date
object in .Net. So regardless of how you obtain the value, once you strip off the time - you have to remember that it doesn't really represent "midnight", even though that's the value you're working with.
If you really want a fully correct solution to this problem, the best approach is to use NodaTime. The LocalDate
class properly represents a date without a time. You can get the current date for any time zone, including the local system time zone:
using NodaTime;
...
Instant now = SystemClock.Instance.Now;
DateTimeZone zone1 = DateTimeZoneProviders.Tzdb.GetSystemDefault();
LocalDate todayInTheSystemZone = now.InZone(zone1).Date;
DateTimeZone zone2 = DateTimeZoneProviders.Tzdb["America/New_York"];
LocalDate todayInTheOtherZone = now.InZone(zone2).Date;
If you don't want to use Noda Time, there is now another option. I've contributed an implementation of a date-only object to the .Net CoreFX Lab project. You can find the System.Time
package object in their MyGet feed. Once added to your project, you will find you can do any of the following:
using System;
...
Date localDate = Date.Today;
Date utcDate = Date.UtcToday;
Date tzSpecificDate = Date.TodayInTimeZone(anyTimeZoneInfoObject);
A bit long winded but it works for me: try this::
=SUM(IF(OR(ISBLANK(AU2), NOT(ISERR(YEAR(AU2)))),0,1)
+IF(OR(ISBLANK(AV2), NOT(ISERR(YEAR(AV2)))),0,1))
first part of if will allow cell to be blank or if there is something in the cell it tries to convert to a year, if there is an error or there is something other than a date result = 1, do the same for each cell and sum the result

The inArray
function returns the index of the object supplied as the first argument to the function in the array supplied as the second argument to the function.
When inArray
returns 0
it is indicating that the first argument was found at the first position of the supplied array.
To use inArray
within an if statement use:
if(jQuery.inArray("test", myarray) != -1) {
console.log("is in array");
} else {
console.log("is NOT in array");
}
inArray
returns -1
when the first argument passed to the function is not found in the array passed as the second argument.
