After ten years, you can read this training explanation on the official documentation.
I had the same problem and tried most of the solutions suggested above, but none worked for me. Eventually, I rebuild my entire com.springframework (maven) repository (by simply deleting .m2/org/springworkframework directory).
It worked for me.
:focus
pseudo-classAs pure CSS solution, you could achieve sort of the effect by using a tabindex
attribute for the image, and :focus
pseudo-class as follows:
<img class="crossRotate" src="http://placehold.it/100" tabindex="1" />
.crossRotate {
outline: 0;
/* other styles... */
}
.crossRotate:focus {
-webkit-transform: rotate(45deg);
-ms-transform: rotate(45deg);
transform: rotate(45deg);
}
Note: Using this approach, the image gets rotated onclick (focused), to negate the rotation, you'll need to click somewhere out of the image (blured).
:checked
pseudo-classThis is one of my favorite methods. In this approach, there's a hidden checkbox input and a <label>
element which wraps the image.
Once you click on the image, the hidden input is checked because of using for
attribute for the label.
Hence by using the :checked
pseudo-class and adjacent sibling selector +
, we could get the image to be rotated:
<input type="checkbox" id="hacky-input">
<label for="hacky-input">
<img class="crossRotate" src="http://placehold.it/100">
</label>
#hacky-input {
display: none; /* Hide the input */
}
#hacky-input:checked + label img.crossRotate {
-webkit-transform: rotate(45deg);
-ms-transform: rotate(45deg);
transform: rotate(45deg);
}
WORKING DEMO #2 (Applying the rotate
to the label gives a better experience).
If using JavaScript/jQuery is an option, you could toggle a .active
class by .toggleClass()
to trigger the rotation effect, as follows:
$('.crossRotate').on('click', function(){
$(this).toggleClass('active');
});
.crossRotate.active {
/* vendor-prefixes here... */
transform: rotate(45deg);
}
In Eclipse Gallileo:

A design pattern is a common way of solving a recurring problem. Classes in all design patterns are just normal classes. What is important is how they are structured and how they work together to solve a given problem in the best possible way.
The Facade design pattern simplifies the interface to a complex system; because it is usually composed of all the classes which make up the subsystems of the complex system.
A Facade shields the user from the complex details of the system and provides them with a simplified view
of it which is easy to use
. It also decouples
the code that uses the system from the details of the subsystems, making it easier to modify the system later.
http://www.dofactory.com/Patterns/PatternFacade.aspx
http://www.blackwasp.co.uk/Facade.aspx
Also, what is important while learning design patterns is to be able to recognize which pattern fits your given problem and then using it appropriately. It is a very common thing to misuse a pattern or trying to fit it to some problem just because you know it. Be aware of those pitfalls while learning\using design patterns.
This was happening for me in my Apache/2.4.18 (Ubuntu) setup. In my case, the error I was seeing was:
... AH01144: No protocol handler was valid for the URL /~socket.io/. If you are using a DSO version of mod_proxy, make sure the proxy submodules are included in the configuration using LoadModule.
The configuration related to this was:
ProxyPass /~socket.io/ ws://127.0.0.1:8090/~socket.io/
ProxyPassReverse /~socket.io/ ws://127.0.0.1:8090/~socket.io/
"No protocol handler was valid for the URL /~socket.io/
" meant that Apache could not handle the request being sent to "ws://127.0.0.1:8090/~socket.io/
"
I had proxy_http
loaded, but also needed proxy_wstunnel
. Once that was enabled all was good.
Use /[^0-9.,]+/
if you want floats.
Just as there are printer drivers that do not connect to a printer at all but rather write to a PDF file, analogously there are virtual audio drivers available that do not connect to a physical microphone at all but can pipe input from other sources such as files or other programs.
I hope I'm not breaking any rules by recommending free/donation software, but VB-Audio Virtual Cable should let you create a pair of virtual input and output audio devices. Then you could play an MP3 into the virtual output device and then set the virtual input device as your "microphone". In theory I think that should work.
If all else fails, you could always roll your own virtual audio driver. Microsoft provides some sample code but unfortunately it is not applicable to the older Windows XP audio model. There is probably sample code available for XP too.
Make sure drush is installed (you may also need to make sure the dblog module is enabled) and use:
drush watchdog-show --tail
Available in drush v8 and below.
This will give you a live look at the logs from your console.
The solution depends on a few things.
Is the default value dependent on other information available at creation time? Can you wipe the database with minimal consequences?
If you answered the first question yes, then you want to use Jim's solution
If you answered the second question yes, then you want to use Daniel's solution
If you answered no to both questions, you're probably better off adding and running a new migration.
class AddDefaultMigration < ActiveRecord::Migration
def self.up
change_column :tasks, :status, :string, :default => default_value, :null => false
end
end
:string can be replaced with any type that ActiveRecord::Migration recognizes.
CPU is cheap so the redefinition of Task in Jim's solution isn't going to cause many problems. Especially in a production environment. This migration is proper way of doing it as it is loaded it and called much less often.
The subversion program code is linked into the TortoiseSVN binary. You can install a compatible discrete version if you need to access the repository from the command line.
UPDATE: Recent versions of the TortoiseSVN package can install a discrete svn.exe in addition to the one linked into the GUI binary. It is located in the same bin directory where the main program is installed. In the installer, the command line tools need to be selected for this:
(If you have already installed TortoiseSVN, then rerun the installer and select "Modify")
Here's my C mini library for trimming left, right, both, all, in place and separate, and trimming a set of specified characters (or white space by default).
#ifndef STRLIB_H_
#define STRLIB_H_ 1
enum strtrim_mode_t {
STRLIB_MODE_ALL = 0,
STRLIB_MODE_RIGHT = 0x01,
STRLIB_MODE_LEFT = 0x02,
STRLIB_MODE_BOTH = 0x03
};
char *strcpytrim(char *d, // destination
char *s, // source
int mode,
char *delim
);
char *strtriml(char *d, char *s);
char *strtrimr(char *d, char *s);
char *strtrim(char *d, char *s);
char *strkill(char *d, char *s);
char *triml(char *s);
char *trimr(char *s);
char *trim(char *s);
char *kill(char *s);
#endif
#include <strlib.h>
char *strcpytrim(char *d, // destination
char *s, // source
int mode,
char *delim
) {
char *o = d; // save orig
char *e = 0; // end space ptr.
char dtab[256] = {0};
if (!s || !d) return 0;
if (!delim) delim = " \t\n\f";
while (*delim)
dtab[*delim++] = 1;
while ( (*d = *s++) != 0 ) {
if (!dtab[0xFF & (unsigned int)*d]) { // Not a match char
e = 0; // Reset end pointer
} else {
if (!e) e = d; // Found first match.
if ( mode == STRLIB_MODE_ALL || ((mode != STRLIB_MODE_RIGHT) && (d == o)) )
continue;
}
d++;
}
if (mode != STRLIB_MODE_LEFT && e) { // for everything but trim_left, delete trailing matches.
*e = 0;
}
return o;
}
// perhaps these could be inlined in strlib.h
char *strtriml(char *d, char *s) { return strcpytrim(d, s, STRLIB_MODE_LEFT, 0); }
char *strtrimr(char *d, char *s) { return strcpytrim(d, s, STRLIB_MODE_RIGHT, 0); }
char *strtrim(char *d, char *s) { return strcpytrim(d, s, STRLIB_MODE_BOTH, 0); }
char *strkill(char *d, char *s) { return strcpytrim(d, s, STRLIB_MODE_ALL, 0); }
char *triml(char *s) { return strcpytrim(s, s, STRLIB_MODE_LEFT, 0); }
char *trimr(char *s) { return strcpytrim(s, s, STRLIB_MODE_RIGHT, 0); }
char *trim(char *s) { return strcpytrim(s, s, STRLIB_MODE_BOTH, 0); }
char *kill(char *s) { return strcpytrim(s, s, STRLIB_MODE_ALL, 0); }
The one main routine does it all.
It trims in place if src == dst, otherwise,
it works like the strcpy
routines.
It trims a set of characters specified in the string delim, or white space if null.
It trims left, right, both, and all (like tr).
There is not much to it, and it iterates over the string only once. Some folks might complain that trim right starts on the left, however, no strlen is needed which starts on the left anyway. (One way or another you have to get to the end of the string for right trims, so you might as well do the work as you go.) There may be arguments to be made about pipelining and cache sizes and such -- who knows. Since the solution works from left to right and iterates only once, it can be expanded to work on streams as well. Limitations: it does not work on unicode strings.
Set the default value for the active
argument in the route.
With the excellent matplotlib
and numpy
packages
from matplotlib import pyplot as mp
import numpy as np
def gaussian(x, mu, sig):
return np.exp(-np.power(x - mu, 2.) / (2 * np.power(sig, 2.)))
x_values = np.linspace(-3, 3, 120)
for mu, sig in [(-1, 1), (0, 2), (2, 3)]:
mp.plot(x_values, gaussian(x_values, mu, sig))
mp.show()
I have briefly discussed this question in a table so you can conclude whether to go with InnoDB or MyISAM.
Here is a small overview of which db storage engine you should use in which situation:
MyISAM InnoDB ---------------------------------------------------------------- Required full-text search Yes 5.6.4 ---------------------------------------------------------------- Require transactions Yes ---------------------------------------------------------------- Frequent select queries Yes ---------------------------------------------------------------- Frequent insert, update, delete Yes ---------------------------------------------------------------- Row locking (multi processing on single table) Yes ---------------------------------------------------------------- Relational base design Yes
Summary
library(stringi)
group <- c('12357e', '12575e', '12575e', ' 197e18', 'e18947')
pattern <- "e"
replacement <- ""
group <- str_replace(group, pattern, replacement)
group
[1] "12357" "12575" "12575" " 19718" "18947"
apply this code for get the ipaddress:
if (getenv('HTTP_X_FORWARDED_FOR')) { $pipaddress = getenv('HTTP_X_FORWARDED_FOR');
$ipaddress = getenv('REMOTE_ADDR');
echo "Your Proxy IP address is : ".$pipaddress. "(via $ipaddress)" ; }
else { $ipaddress = getenv('REMOTE_ADDR'); echo "Your IP address is : $ipaddress"; }

You can try:
#!/bin/bash
d=$(date +%Y-%m-%d)
echo "$d"
EDIT: Changed y to Y for 4 digit date as per QuantumFool's comment.
A simple DIY way would be to make the grid yourself:
import matplotlib.pyplot as plt
fig = plt.figure()
ax = fig.add_subplot(111)
ax.plot([1,2,3], [2,3,4], 'ro')
for xmaj in ax.xaxis.get_majorticklocs():
ax.axvline(x=xmaj, ls='-')
for xmin in ax.xaxis.get_minorticklocs():
ax.axvline(x=xmin, ls='--')
for ymaj in ax.yaxis.get_majorticklocs():
ax.axhline(y=ymaj, ls='-')
for ymin in ax.yaxis.get_minorticklocs():
ax.axhline(y=ymin, ls='--')
plt.show()
You can do simply by replacing html
$('#mySelect')
.html('<option value="whatever" selected>text</option>')
.trigger('change');
Assuming you have access to STL:
std::string filename("filename.conf");
std::string::size_type idx;
idx = filename.rfind('.');
if(idx != std::string::npos)
{
std::string extension = filename.substr(idx+1);
}
else
{
// No extension found
}
Edit: This is a cross platform solution since you didn't mention the platform. If you're specifically on Windows, you'll want to leverage the Windows specific functions mentioned by others in the thread.
Use the escape
function of querystring
. It generates a URL safe string.
var escaped_str = require('querystring').escape('Photo on 30-11-12 at 8.09 AM #2.jpg');
console.log(escaped_str);
// prints 'Photo%20on%2030-11-12%20at%208.09%20AM%20%232.jpg'
I would use Different IDs but assign each DIV the same class.
<div id="c-1" class="countdown"></div>
<div id="c-2" class="countdown"></div>
This also has the added benefit of being able to reconstruct the IDs based off of the return of jQuery('.countdown').length
Ok what about adding multiple classes to each countdown timer. IE:
<div class="countdown c-1"></div>
<div class="countdown c-2"></div>
<div class="countdown c-1"></div>
That way you get the best of both worlds. It even allows repeat 'IDS'
Here's how i am calling my modal
<a data-toggle="modal" data-id="190" data-target="#modal-popup">Open</a>
Here's how i am obtaining value in the modal
$('#modal-popup').on('show.bs.modal', function(e) {
console.log($(e.relatedTarget).data('id')); // 190 will be printed
});
In most cases without adding the !important
to the CSS code, it won't work.
!important
a, a:active, a:focus{
outline: none !important; /* Works in Firefox, Chrome, IE8 and above */
}
Or any other code:
button::-moz-focus-inner {
border: 0 !important;
}

calendar.setTime(date);
System.out.println(calendar.getTime());

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)
For future questions, It's also possible to do it by using float
property and clearing it in each 3 elements.
Here's an example I've made.
.grid {_x000D_

Elaborateling slighty on the nice answer by Jon Skeet, this could be versatile:
public static IEnumerable<T> Directional<T>(this IList<T> items, bool Forwards) {
if (Forwards) foreach (T item in items) yield return item;
else for (int i = items.Count-1; 0<=i; i--) yield return items[i];
}
And then use as
foreach (var item in myList.Directional(forwardsCondition)) {
.
.
}
The issue is because your data source is not setup properly, to do that please verify your data source connection, in order to do that first navigate to Report Service Configuration Manager through
clicking on the start -> Start All -> Microsoft SQL Server ->Configuration Tool -> “Report Service Configuration Manager”
The open Report Manager URL and then navigate to the Data Source folder, see in the picture below
Then Create a Data Source or configure the one that is already there by right click on your database source and select "Manage" as is shown below
Now on the properties tab, on your left menu, fill out the data source with your connection string and username and password, after that click on test connection, and if the connection was successful, then click "Apply"
Navigate to the folder that contains your report in this case "SurveyLevelReport"
And Finally set your Report to the Data Source that you set up previously, and click Apply
You should use Haversine Distance Formulas
Haversine Formulas used to calculate the great distance between two points on the earth.
public void haversine(double lat1, double lon1, double lat2, double lon2) {
double Rad = 6372.8; //Earth's Radius In kilometers
// TODO Auto-generated method stub
double dLat = Math.toRadians(lat2 - lat1);
double dLon = Math.toRadians(lon2 - lon1);
lat1 = Math.toRadians(lat1);
lat2 = Math.toRadians(lat2);
double a = Math.sin(dLat / 2) * Math.sin(dLat / 2) + Math.sin(dLon / 2) * Math.sin(dLon / 2) * Math.cos(lat1) * Math.cos(lat2);
double c = 2 * Math.asin(Math.sqrt(a));
haverdistanceKM = Rad * c;

i had the same problem in visual studio 2019 and it resolved by searching in the searchbar inside visual studio: manage NuGet packages > oracle.ManagedDataAccess (first result) install it. and then it should works!
Let me help you understand it with an example of "codaddict's algorithm"
'Dictionary in C#' is 'Hashmap in Java' in parallel universe.
Some implementations are different. See the example below to understand better.
Declaring Java HashMap:
Map<Integer, Integer> pairs = new HashMap<Integer, Integer>();
Declaring C# Dictionary:
Dictionary<int, int> Pairs = new Dictionary<int, int>();
Getting a value from a location:
pairs.get(input[i]); // in Java
Pairs[input[i]]; // in C#
Setting a value at location:
pairs.put(k - input[i], input[i]); // in Java
Pairs[k - input[i]] = input[i]; // in C#
An Overall Example can be observed from below Codaddict's algorithm.
codaddict's algorithm in Java:
import java.util.HashMap;
public class ArrayPairSum {
public static void printSumPairs(int[] input, int k)
{
Map<Integer, Integer> pairs = new HashMap<Integer, Integer>();
for (int i = 0; i < input.length; i++)
{
if (pairs.containsKey(input[i]))
System.out.println(input[i] + ", " + pairs.get(input[i]));
else
pairs.put(k - input[i], input[i]);
}
}
public static void main(String[] args)
{
int[] a = { 2, 45, 7, 3, 5, 1, 8, 9 };
printSumPairs(a, 10);
}
}
Codaddict's algorithm in C#
using System;
using System.Collections.Generic;
class Program
{
static void checkPairs(int[] input, int k)
{
Dictionary<int, int> Pairs = new Dictionary<int, int>();
for (int i = 0; i < input.Length; i++)
{
if (Pairs.ContainsKey(input[i]))
{
Console.WriteLine(input[i] + ", " + Pairs[input[i]]);
}
else
{
Pairs[k - input[i]] = input[i];
}
}
}
static void Main(string[] args)
{
int[] a = { 2, 45, 7, 3, 5, 1, 8, 9 };
//method : codaddict's algorithm : O(n)
checkPairs(a, 10);
Console.Read();
}
}
I have a simpler solution. In your destination page (irc_online.php) add an auto-refresh tag in the header.
If you want to fully automate the process (i.e. you want to increment the version number without having to know what the current version number is), you can do this:
mvn build-helper:parse-version versions:set -DnewVersion=\${parsedVersion.majorVersion}.\${parsedVersion.minorVersion}.\${parsedVersion.nextIncrementalVersion} versions:commit
You need to generate a python file from your ui file with the pyuic tool (site-packages\pyqt4\bin)
pyuic form1.ui > form1.py
with pyqt4
pyuic4.bat form1.ui > form1.py
Then you can import the form1 into your script.
Just add overflow:auto; to parent div
<div style="width: 100%;overflow:auto;">
<div style="float:left; width: 80%">
</div>
<div style="float:right;">
</div>
</div>
<script type = "text/javascript">
function get_values(input_id)
{
var input = document.getElementById(input_id).value;
document.write(input);
}
</script>
<!--Insert more code here-->
<input type = "text" id = "textfield">
<input type = "button" onclick = "get('textfield')" value = "submit">
Next time you ask a question here, include more detail and what you have tried.
A percentage in the value of the font-size
property is relative to the parent element’s font size. CSS 2.1 says this obscurely and confusingly (referring to “inherited font size”), but CSS3 Text says it very clearly.
The parent of the body
element is the root element, i.e. the html
element. Unless set in a style sheet, the font size of the root element is implementation-dependent. It typically depends on user settings.
Setting font-size: 100%
is pointless in many cases, as an element inherits its parent’s font size (leading to the same result), if no style sheet sets its own font size. However, it can be useful to override settings in other style sheets (including browser default style sheets).
For example, an input
element typically has a setting in browser style sheet, making its default font size smaller than that of copy text. If you wish to make the font size the same, you can set
input { font-size: 100% }
For the body
element, the logically redundant setting font-size: 100%
is used fairly often, as it is believed to help against some browser bugs (in browsers that probably have lost their significance now).
@Future-searchers: you can use aspell to do the dictionary checks, it has bindings in ruby and python. It would make your job much simpler.

I force reload my component using *ngIf.
All the components inside my container goes back to the full lifecycle hooks .
In the template :
<ng-container *ngIf="_reload">
components here
</ng-container>
Then in the ts file :
public _reload = true;
private reload() {
setTimeout(() => this._reload = false);
setTimeout(() => this._reload = true);
}
I've developed a nice JS solution - which is suitable for entirely-responsive HTML (i.e. HTML built with percentages)
I use only "em" to define font-sizes.
html font size is set to 10 pixels:
html {
font-size: 100%;
font-size: 62.5%;
}
I call a font-resizing function on document-ready:
// this requires JQuery
function doResize() {
// FONT SIZE
var ww = $('body').width();
var maxW = [your design max-width here];
ww = Math.min(ww, maxW);
var fw = ww*(10/maxW);
var fpc = fw*100/16;
var fpc = Math.round(fpc*100)/100;
$('html').css('font-size',fpc+'%');
}
This solution might break R but here is an easiest solution that works 99% of time.
You need to do is just:
install.packages('package-name',repos='http://cran.us.r-project.org')
As mentioned by the author over here
Update (27-Jun-18): It looks like there was a major update to jsdom
that causes the original answer to no longer work. I found this answer that explains how to use jsdom
now. I've copied the relevant code below.
var jsdom = require("jsdom");
const { JSDOM } = jsdom;
const { window } = new JSDOM();
const { document } = (new JSDOM('')).window;
global.document = document;
var $ = jQuery = require('jquery')(window);
Note: The original answer fails to mention that it you will need to install jsdom as well using npm install jsdom
Update (late 2013): The official jQuery team finally took over the management of the jquery
package on npm:
npm install jquery
Then:
require("jsdom").env("", function (err, window) {
if (err) {
console.error(err);
return;
}
var $ = require("jquery")(window);
});
borderColor on any view(or UIView Subclass) could also be set using storyboard with a little bit of coding and this approach could be really handy if you're setting border color on multiple UI Objects.
Below are the steps how to achieve it,
P.S: Remember, Categories can't have stored properties. 'borderUIColor' is used as a calculated property, just as a reference to achieve what we're focusing on.
Please have a look at the below code sample;
Objective C:
Interface File:
#import <QuartzCore/QuartzCore.h>
#import <UIKit/UIKit.h>
@interface CALayer (BorderProperties)
// This assigns a CGColor to borderColor.
@property (nonatomic, assign) UIColor* borderUIColor;
@end
Implementation File:
#import "CALayer+BorderProperties.h"
@implementation CALayer (BorderProperties)
- (void)setBorderUIColor:(UIColor *)color {
self.borderColor = color.CGColor;
}
- (UIColor *)borderUIColor {
return [UIColor colorWithCGColor:self.borderColor];
}
@end
Swift 2.0:
extension CALayer {
var borderUIColor: UIColor {
set {
self.borderColor = newValue.CGColor
}
get {
return UIColor(CGColor: self.borderColor!)
}
}
}
And finally go to your storyboard/XIB, follow the remaining steps;
You've to set layer.borderWidth property value to at least 1 to see the border color.
Build and Run. Happy Coding. :)
You could use *ngIf="teamMembers != 0"
to check whether data is present
If you are using System.Web.Script.Serialization
in the .NET framework you can put a ScriptIgnore
attribute on the members that shouldn't be serialized. See the example taken from here:
Consider the following (simplified) case:
public class User { public int Id { get; set; } public string Name { get; set; } [ScriptIgnore] public bool IsComplete { get { return Id > 0 && !string.IsNullOrEmpty(Name); } } }
In this case, only the Id and the Name properties will be serialized, thus the resulting JSON object would look like this:
{ Id: 3, Name: 'Test User' }
PS. Don't forget to add a reference to "System.Web.Extensions
" for this to work
You can use this to change tooltip-arrow color
.tooltip.bottom .tooltip-arrow {
top: 0;
left: 50%;
margin-left: -5px;
border-bottom-color: #000000; /* black */
border-width: 0 5px 5px;
}
Use: LOGGER.log(Level.INFO, "Got an exception.", e);
or LOGGER.info("Got an exception. " + e.getMessage())
;
you should use []
var x = ConfigurationManager.AppSettings["APIKey"];
A URL that starts with the URL scheme and scheme specific part (http://
, https://
, ftp://
, etc.) is an absolute URL.
Any other URL is a relative URL and needs a base URL the relative URL is resolved from (and thus depend on) that is the URL of the resource the reference is used in if not declared otherwise.
Take a look at RFC 2396 – Appendix C for examples of resolving relative URLs.
You can use the ControlFormat method:
ComboBox1.ControlFormat.RemoveAllItems
Here I would like to present another alternative to Flatten function. This may help to understand what is going on internally. The alternative method adds three more code lines. Instead of using
#==========================================Build a Model
model = tf.keras.models.Sequential()
model.add(keras.layers.Flatten(input_shape=(28, 28, 3)))#reshapes to (2352)=28x28x3
model.add(layers.experimental.preprocessing.Rescaling(1./255))#normalize
model.add(keras.layers.Dense(128,activation=tf.nn.relu))
model.add(keras.layers.Dense(2,activation=tf.nn.softmax))
model.build()
model.summary()# summary of the model
we can use
#==========================================Build a Model
tensor = tf.keras.backend.placeholder(dtype=tf.float32, shape=(None, 28, 28, 3))
model = tf.keras.models.Sequential()
model.add(keras.layers.InputLayer(input_tensor=tensor))
model.add(keras.layers.Reshape([2352]))
model.add(layers.experimental.preprocessing.Rescaling(1./255))#normalize
model.add(keras.layers.Dense(128,activation=tf.nn.relu))
model.add(keras.layers.Dense(2,activation=tf.nn.softmax))
model.build()
model.summary()# summary of the model
In the second case, we first create a tensor (using a placeholder) and then create an Input layer. After, we reshape the tensor to flat form. So basically,
Create tensor->Create InputLayer->Reshape == Flatten
Flatten is a convenient function, doing all this automatically. Of course both ways has its specific use cases. Keras provides enough flexibility to manipulate the way you want to create a model.
Create your own unistd.h header and include the needed headers for function prototypes.
You must use LEFT JOIN
instead of INNER JOIN
SELECT person.person_id, COUNT(appointment.person_id) AS "number_of_appointments"
FROM person
LEFT JOIN appointment ON person.person_id = appointment.person_id
GROUP BY person.person_id;
You can use a tool I wrote that bypasses the limit.
It saves the Tweets in a JSON format.
Use continue statement instead of return to skip an iteration in JS loops.
In case if you need create text file based on one single string:
import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Paths;
public class StringWriteSample {
public static void main(String[] args) {
String text = "This is text to be saved in file";
try {
Files.write(Paths.get("my-file.txt"), text.getBytes());
} catch (IOException e) {
e.printStackTrace();
}
}
}
it checks valid number integers or float or double not a string
regex that i used
simple regex
1. ^[0-9]*[.]?[0-9]*$
advance regex
2. ^-?[\d.]+(?:e-?\d+)?$
eg:only numbers
var str='1232323';
var reg=/^[0-9]*[.]?[0-9]*$/;
console.log(reg.test(str))
_x000D_
eg:123434
eg:.1232323
eg:12.3434434
eg:1122212.efsffasf
eg:2323fdf34434
eg:0.3232rf3333
////////////////////////////////////////////////////////////////////
^-?[\d.]+(?:e-?\d+)?$
eg:13123123
eg:12344.3232
eg:2323323e4
eg:0.232332
See if the plugin has a 'skip' configuration parameter. Nearly all do. if it does, just add it to a declaration in the child:

If not, then use:

Nuru answer actually works, only thing is remove this line frame = cv2.flip(frame,0)
under if ret==True:
loop which will output the video file without flipping
try this code
import serial.tools.list_ports
for i in serial.tools.list_ports.comports():
print(i)
it returns
COM1 - Port de communication (COM1)
COM5 - USB-SERIAL CH340 (COM5)
if you just wont the name of the port for exemple COM1
import serial.tools.list_ports
for i in serial.tools.list_ports.comports():
print(str(i).split(" ")[0])
it returns
COM1
COM5

There are a few Java-based XML diff and merge tools listed here:
Open Source XML Diff written in Java
Added links:
I realize this is a little old, but, yes it can be done. Some javascript to get you started:
viewport = document.querySelector("meta[name=viewport]");
viewport.setAttribute('content', 'width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0');
Just change the parts you need and Mobile Safari will respect the new settings.
Update:
If you don't already have the meta viewport tag in the source, you can append it directly with something like this:
var metaTag=document.createElement('meta');
metaTag.name = "viewport"
metaTag.content = "width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0"
document.getElementsByTagName('head')[0].appendChild(metaTag);
Or if you're using jQuery:
$('head').append('<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0">');
You can use this commands:
docker exec -it yournamecontainer psql -U postgres -c "CREATE DATABASE mydatabase ENCODING 'LATIN1' TEMPLATE template0 LC_COLLATE 'C' LC_CTYPE 'C';"
docker exec -it yournamecontainer psql -U postgres -c "GRANT ALL PRIVILEGES ON DATABASE postgres TO postgres;"
$limit = (Get-Date).AddDays(-15)
$path = "C:\Some\Path"
# Delete files older than the $limit.
Get-ChildItem -Path $path -Force | Where-Object { !$_.PSIsContainer -and $_.CreationTime -lt $limit } | Remove-Item -Force -Recurse
This will delete old folders and it content.

As noted above the problem is in specifying the path to your file. The default path in OS X is your home directory (/Users/macbook represented by ~ in terminal ...you can change or rename the home directory with the advanced options in System Preferences > Users & Groups).
Or you can specify the path from the drive to your file in the filename:
path = "/Users/macbook/Documents/MyPython/"
myFile = path + fileName
You can also catch the File Not Found Error and give another response using try:
try:
with open(filename) as f:
sequences = pick_lines(f)
except FileNotFoundError:
print("File not found. Check the path variable and filename")
exit()
Click on the WAMP server icon and from the menu under Config Files select
httpd.conf
. A long text file will open up in notepad. In this file scroll
down to the line that reads Port 80
and change this to read Port 8080
,
Save the file and close notepad. Once again click on the wamp server icon and
select restart all services. One more change needs to be made before we are
done. In Windows Explorer find the location where WAMP server was installed
which is by Default C:\Wamp
.
Update : On a newer version of WAMP, click the WAMP server icon > Apache > httpd.conf
, then change the line Listen 80
to Listen 8080
or any port you want.
Update: On 3.1.6 version of WAMP , right click on the wamp server icon in the taskbar ,select "tools"-> "Port used by Apache:80" -> "use a port other than 80", an input box will pop up , input a new port in it,click confirm button , then restart wamp .
Seems that EditText apply the hintTextColor only if the text is empty. So simple solution will be like this
Editable text = mEditText.getText();
mEditText.setText(null);
mEditText.setHintTextColor(color);
mEditText.setText(text);
If you have multiple fields, you can extend the EditText and write a method which executes this logic and use that method instead.
The function here returns the parameter by name. With tiny changes you will be able to return base url, parameter or anchor.
function getUrlParameter(name) {
var urlOld = window.location.href.split('?');
urlOld[1] = urlOld[1] || '';
var urlBase = urlOld[0];
var urlQuery = urlOld[1].split('#');
urlQuery[1] = urlQuery[1] || '';
var parametersString = urlQuery[0].split('&');
if (parametersString.length === 1 && parametersString[0] === '') {
parametersString = [];
}
// console.log(parametersString);
var anchor = urlQuery[1] || '';
var urlParameters = {};
jQuery.each(parametersString, function (idx, parameterString) {
paramName = parameterString.split('=')[0];
paramValue = parameterString.split('=')[1];
urlParameters[paramName] = paramValue;
});
return urlParameters[name];
}
To support older version Space can be replaced with View as below. Add this view between after left most component and before right most component. This view with weight=1 will stretch and fill the space
<View
android:layout_width="0dp"
android:layout_height="20dp"
android:layout_weight="1" />
Complete sample code is given here. It has has 4 components. Two arrows will be on the right and left side. The Text and Spinner will be in the middle.
<ImageButton
android:id="@+id/btnGenesis"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center|center_vertical"
android:layout_marginBottom="2dp"
android:layout_marginLeft="0dp"
android:layout_marginTop="2dp"
android:background="@null"
android:gravity="left"
android:src="@drawable/prev" />
<View
android:layout_width="0dp"
android:layout_height="20dp"
android:layout_weight="1" />

These solutions has bug. When use solutions at below, windows has delay at closing.
Menu.setApplicationMenu(null),
&&
const updateErrorWindow = new BrowserWindow({autoHideMenuBar: true});
I used solution at below. This is better for now.
const window= new BrowserWindow({...});
window.setMenuBarVisibility(false);
Use "target" attribute and remove the 'compiler' attribute. See here. So it should go something like this:
<target name="compile">
<javac target="1.5" srcdir=.../>
</target>
Hope this helps
i found this one is more easy for preventing type error:
public enum Modes {
some-really-long-string,
mode1,
mode2,
mode3;
String str;
Modes(){
this.str = super.name();
}
@Override
@NonNull
public String toString() {
return str;
}
however - this may work when you need to use a String on a log/println or whenever java compiles the toString() method automatically, but on a code line like this ->
// sample method that require (string,value)
intent.putExtra(Modes.mode1 ,shareElement.getMode()); // java error
// first argument enum does not return value
instead as mentioned above you will still have to extend the enum and use .name()
in those cases like this:
intent.putExtra(Modes.mode1.name() ,shareElement.getMode());
This is like FlappySock's answer, but I added a callback to it because I didn't like the layout and how the Boolean was getting returned. In the comments of that answer from Nick Miller:
In my experience, if the end point can be reached, but there is no server on the endpoint able to receive the connection, then AsyncWaitHandle.WaitOne will be signaled, but the socket will remain unconnected
So to me, it seems relying on what is returned can be dangerous - I prefer to use socket.Connected
. I set a nullable Boolean and update it in the callback function. I also found it doesn't always finish reporting the result before returning to the main function - I handle for that, too, and make it wait for the result using the timeout:
private static bool? areWeConnected = null;
private static bool checkSocket(string svrAddress, int port)
{
IPEndPoint endPoint = new IPEndPoint(IPAddress.Parse(svrAddress), port);
Socket socket = new Socket(endPoint.AddressFamily, SocketType.Stream, ProtocolType.Tcp);
int timeout = 5000; // int.Parse(ConfigurationManager.AppSettings["socketTimeout"].ToString());
int ctr = 0;
IAsyncResult ar = socket.BeginConnect(endPoint, Connect_Callback, socket);
ar.AsyncWaitHandle.WaitOne( timeout, true );
// Sometimes it returns here as null before it's done checking the connection
// No idea why, since .WaitOne() should block that, but it does happen
while (areWeConnected == null && ctr < timeout)
{
Thread.Sleep(100);
ctr += 100;
} // Given 100ms between checks, it allows 50 checks
// for a 5 second timeout before we give up and return false, below
if (areWeConnected == true)
{
return true;
}
else
{
return false;
}
}
private static void Connect_Callback(IAsyncResult ar)
{
areWeConnected = null;
try
{
Socket socket = (Socket)ar.AsyncState;
areWeConnected = socket.Connected;
socket.EndConnect(ar);
}
catch (Exception ex)
{
areWeConnected = false;
// log exception
}
}

This is a quite confusing way of using Apache configuration directives.
Technically, the first bit is equivalent to
Allow From All
This is because Order Deny,Allow
makes the Deny directive evaluated before the Allow Directives.
In this case, Deny and Allow conflict with each other, but Allow, being the last evaluated will match any user, and access will be granted.
Now, just to make things clear, this kind of configuration is BAD and should be avoided at all cost, because it borders undefined behaviour.
The Limit sections define which HTTP methods have access to the directory containing the .htaccess file.
Here, GET and POST methods are allowed access, and PUT and DELETE methods are denied access. Here's a link explaining what the various HTTP methods are: http://www.w3.org/Protocols/rfc2616/rfc2616-sec9.html
However, it's more than often useless to use these limitations as long as you don't have custom CGI scripts or Apache modules that directly handle the non-standard methods (PUT and DELETE), since by default, Apache does not handle them at all.
It must also be noted that a few other methods exist that can also be handled by Limit, namely CONNECT, OPTIONS, PATCH, PROPFIND, PROPPATCH, MKCOL, COPY, MOVE, LOCK, and UNLOCK.
The last bit is also most certainly useless, since any correctly configured Apache installation contains the following piece of configuration (for Apache 2.2 and earlier):
#
# The following lines prevent .htaccess and .htpasswd files from being
# viewed by Web clients.
#
<Files ~ "^\.ht">
Order allow,deny
Deny from all
Satisfy all
</Files>
which forbids access to any file beginning by ".ht".
The equivalent Apache 2.4 configuration should look like:
<Files ~ "^\.ht">
Require all denied
</Files>
Yes, indeed you need to have one child inside your <TouchableHighlight>
.
And, If you don't want to pollute your file with Views
you can use React Fragments to achieve the same.
<TouchableWithoutFeedback>
<React.Fragment>
...
</React.Fragment>
</TouchableWithoutFeedback>
or even better there is a short syntax for React Fragments. So the above code can be written as below:
<TouchableWithoutFeedback>

</>
</TouchableWithoutFeedback>
In my case, when i upgrade vs project to angular 10, I had this errors.
Angular cli creates tsconfig.json
, tsconfig.base.json
and tsconfig.app.json
when i delete tsconfig.json and rename tsconfig.base.json to tsconfig.ts all things will Ok.
you must also change extends inside tsconfig.app.json to tsconfig.json
Looks like clearing the value after focusing and then resetting works.
input.focus();
var tmpStr = input.val();
input.val('');
input.val(tmpStr);
Also seems nobody noticed -x operator on symlinks. A symlink (chain) to a regular file (not classified as executable) fails the test.
Try like below,
$('input[type=text]').val (function () {
return this.value.toUpperCase();
})
You should use input[type=text]
instead of :input
or input
as I believe your intention are to operate on textbox only.

You can change this as your need..
Using pathlib (https://docs.python.org/3/library/pathlib.html)
from pathlib import Path
file = Path('Stud.txt')
file.write_text(file.read_text().replace('A', 'Orange'))
If input and output files were different you would use two different variables for read_text
and write_text
.
If you wanted a change more complex than a single replacement, you would assign the result of read_text
to a variable, process it and save the new content to another variable, and then save the new content with write_text
.
If your file was large you would prefer an approach that does not read the whole file in memory, but rather process it line by line as show by Gareth Davidson in another answer (https://stackoverflow.com/a/4128192/3981273), which of course requires to use two distinct files for input and output.
I had the same problem with a file that I've created on my mac. If I try to run it in a shell with ./filename I got the file not found error message. I think that something was wrong with the file.
what I've done:
open a ssh session to the server
cat filename
copy the output to the clipboard
rm filename
touch filename
vi filename
i for insert mode
paste the content from the clipboard
ESC to end insert mode
:wq!
This worked for me.
CMD.EXE will not execute internal commands contained inside the string. Only actual files can be launched with that string.
You will need to actually call a batch file to do what you want.
BAT1.bat
start cmd.exe /k bat2.bat
BAT2.bat
cd C:\activiti-5.9\setup
ant demo.start
You may want to create a folder called BAT
, and add it's location to your path.
So if you create C:\BAT
, add C:\BAT\;
to the path. The path is located at:
click -> Start -> right-click Computer -> Properties ->
click -> Avanced System Settings -> Environment Variables
select -> Path (From either list. User Variables are specific to
your profile, System Variables are, duh, system-wide.)
Click -> Edit
Press the -> the [END] or [HOME] key.
Type -> C:\BAT\;
Click -> OK -> OK
Now place all your batch files in C:\BAT
and they will be found, regardless of the current directory.
I got here searching for the same error, but from Node.js native driver. The answer for me was combination of answers by campeterson and Prabhat.
The issue is that readPreference
setting defaults to primary
, which then somehow leads to the confusing slaveOk
error. My problem is that I just wan to read from my replica set from any node. I don't even connect to it as to replicaset. I just connect to any node to read from it.
Setting readPreference
to primaryPreferred
(or better to the ReadPreference.PRIMARY_PREFERRED
constant) solved it for me. Just pass it as an option to MongoClient.connect()
or to client.db()
or to any find()
, aggregate()
or other function.
const { MongoClient, ReadPreference } = require('mongodb');
const client = await MongoClient.connect(MONGODB_CONNECTIONSTRING, { readPreference: ReadPreference.PRIMARY_PREFERRED });
Based on the accepted response by tiago, here is a small generic function that exports a numpy array to an image having the same resolution as the array:
import matplotlib.pyplot as plt
import numpy as np
def export_figure_matplotlib(arr, f_name, dpi=200, resize_fact=1, plt_show=False):
"""
Export array as figure in original resolution
:param arr: array of image to save in original resolution
:param f_name: name of file where to save figure
:param resize_fact: resize facter wrt shape of arr, in (0, np.infty)
:param dpi: dpi of your screen
:param plt_show: show plot or not
"""
fig = plt.figure(frameon=False)
fig.set_size_inches(arr.shape[1]/dpi, arr.shape[0]/dpi)
ax = plt.Axes(fig, [0., 0., 1., 1.])
ax.set_axis_off()
fig.add_axes(ax)
ax.imshow(arr)
plt.savefig(f_name, dpi=(dpi * resize_fact))
if plt_show:
plt.show()
else:
plt.close()
As said in the previous reply by tiago, the screen DPI needs to be found first, which can be done here for instance: http://dpi.lv
I've added an additional argument resize_fact
in the function which which you can export the image to 50% (0.5) of the original resolution, for instance.
If you want just the summary of the exception use:
try
{
test();
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
If you want to see the whole stack trace (usually better for debugging) use:
try
{
test();
}
catch (Exception ex)
{
MessageBox.Show(ex.ToString());
}
Another method I sometime use is:
private DoSomthing(int arg1, int arg2, out string errorMessage)
{
int result ;
errorMessage = String.Empty;
try
{
//do stuff
int result = 42;
}
catch (Exception ex)
{
errorMessage = ex.Message;//OR ex.ToString(); OR Free text OR an custom object
result = -1;
}
return result;
}
And In your form you will have something like:
string ErrorMessage;
int result = DoSomthing(1, 2, out ErrorMessage);
if (!String.IsNullOrEmpty(ErrorMessage))
{
MessageBox.Show(ErrorMessage);
}
for Angular 6+ and >=RC.6
.html
<form [formGroup]="formGroup">
<input type="text" formControlName="myName">
</form>
.ts
public formGroup: FormGroup;
this.formGroup.value.myName
should also work.

Ctrl + R - to open the command line and then writes:

You can register a handler for process.on('exit')
and in any other case(SIGINT
or unhandled exception) to call process.exit()
process.stdin.resume();//so the program will not close instantly
function exitHandler(options, exitCode) {
if (options.cleanup) console.log('clean');
if (exitCode || exitCode === 0) console.log(exitCode);
if (options.exit) process.exit();
}
//do something when app is closing
process.on('exit', exitHandler.bind(null,{cleanup:true}));
//catches ctrl+c event
process.on('SIGINT', exitHandler.bind(null, {exit:true}));
// catches "kill pid" (for example: nodemon restart)
process.on('SIGUSR1', exitHandler.bind(null, {exit:true}));
process.on('SIGUSR2', exitHandler.bind(null, {exit:true}));
//catches uncaught exceptions
process.on('uncaughtException', exitHandler.bind(null, {exit:true}));
...and when I got one how to process it (do I need to use Fourier Transform like it was instructed in the above post)?
If you want a "tap" then I think you are interested in amplitude more than frequency. So Fourier transforms probably aren't useful for your particular goal. You probably want to make a running measurement of the short-term (say 10 ms) amplitude of the input, and detect when it suddenly increases by a certain delta. You would need to tune the parameters of:
Although I said you're not interested in frequency, you might want to do some filtering first, to filter out especially low and high frequency components. That might help you avoid some "false positives". You could do that with an FIR or IIR digital filter; Fourier isn't necessary.
my suggestion is...create role in oracle using
create role <role_name>;
then assign privileges to that role using
grant select on <table_name> to <role_name>;
then assign that group of privileges via that role to any user by using
grant <role_name> to <user_name>...;
Maybe it is the case that you have your path in couple of lines, you used enter to make it? If so, then part of you paths might look like that "/\nData/" instead of "/Data/", which causes the problem. Just set it to be in one line and issue is solved!

Can't think of a only css solution, but couldn't you just had a div between those 2 and set in the css the properties to look like a line like shown in the image? If you are using divs as they were table cells this is a pretty simple solution to the problem
Suppose you have a hidden input, named XXX, if you want to assign a value to the following
<script type="text/javascript">
$(document).ready(function(){
$('#XXX').val('any value');
})
</script>
We cannot change the application port from the avtivator but can change from the command line activator "~run 8080"
But to run on the poet 9000 from the activator we need to stop the application which is using this port. We can use the this application to find this and end the process https://technet.microsoft.com/en-in/sysinternals/bb897437.aspx
After this we can run and it will be successful.
Given a regular expression of (foobar)
you can reference the first group using $1
and so on if you have more groups in the replace input field.
You can implement a class that holds the fields you have in your JSON
class MyData
{
public string t;
public bool a;
public object[] data;
public string[][] type;
}
and then use the generic version of DeserializeObject:
MyData tmp = JsonConvert.DeserializeObject<MyData>(json);
foreach (string typeStr in tmp.type[0])
{
// Do something with typeStr
}

Java does not have a datatype for unsigned integers.
You can define a long
instead of an int
if you need to store large values.
You can also use a signed integer as if it were unsigned. The benefit of two's complement representation is that most operations (such as addition, subtraction, multiplication, and left shift) are identical on a binary level for signed and unsigned integers. A few operations (division, right shift, comparison, and casting), however, are different. As of Java SE 8, new methods in the Integer
class allow you to fully use the int
data type to perform unsigned arithmetic:
In Java SE 8 and later, you can use the int data type to represent an unsigned 32-bit integer, which has a minimum value of 0 and a maximum value of 2^32-1. Use the Integer class to use int data type as an unsigned integer. Static methods like
compareUnsigned
,divideUnsigned
etc have been added to the Integer class to support the arithmetic operations for unsigned integers.
Note that int
variables are still signed when declared but unsigned arithmetic is now possible by using those methods in the Integer
class.
Indeed, thanks to the comments to my post here, it looks like sparse directories are the way to go. I believe the following should do it:
svn checkout --depth empty http://svnserver/trunk/proj
svn update --set-depth infinity proj/foo
svn update --set-depth infinity proj/bar
svn update --set-depth infinity proj/baz
Alternatively, --depth immediates
instead of empty
checks out files and directories in trunk/proj
without their contents. That way you can see which directories exist in the repository.
As mentioned in @zigdon's answer, you can also do a non-recursive checkout. This is an older and less flexible way to achieve a similar effect:
svn checkout --non-recursive http://svnserver/trunk/proj
svn update trunk/foo
svn update trunk/bar
svn update trunk/baz
You should be using event.currentTarget. React is mirroring the difference between currentTarget (element the event is attached to) and target (the element the event is currently happening on). Since this is a mouse event, type-wise the two could be different, even if it doesn't make sense for a click.
https://github.com/facebook/react/issues/5733 https://developer.mozilla.org/en-US/docs/Web/API/Event/currentTarget
$('.tag1, .tag2').on('click', function() {
if ($(this).hasClass('clickedTag')){
// code here
} else {
// and here
}
});
or
function dothing() {
if ($(this).hasClass('clickedTag')){
// code here
} else {
// and here
}
}
$('.tag1, .tag2').on('click', dothing);
or
$('[class^=tag]').on('click', dothing);
Use a character set: [a-zA-Z]
matches one letter from A–Z in lowercase and uppercase. [a-zA-Z]+
matches one or more letters and ^[a-zA-Z]+$
matches only strings that consist of one or more letters only (^
and $
mark the begin and end of a string respectively).
If you want to match other letters than A–Z, you can either add them to the character set: [a-zA-ZäöüßÄÖÜ]
. Or you use predefined character classes like the Unicode character property class \p{L}
that describes the Unicode characters that are letters.
You can use
helpers.<helper>
in Rails 5+ (or ActionController::Base.helpers.<helper>
)view_context.<helper>
(Rails 4 & 3) (WARNING: this instantiates a new view instance per call)@template.<helper>
(Rails 2) singleton.helper
include
the helper in the controller (WARNING: will make all helper methods into controller actions)I haven't played with these settings myself so this is just speculation but if we think about this issue as normal cores and threads in a distributed system then in your cluster you can use up to 12 cores (4 * 3 machines) and 24 threads (8 * 3 machines). In your first two examples you are giving your job a fair number of cores (potential computation space) but the number of threads (jobs) to run on those cores is so limited that you aren't able to use much of the processing power allocated and thus the job is slower even though there is more computation resources allocated.
you mention that your concern was in the shuffle step - while it is nice to limit the overhead in the shuffle step it is generally much more important to utilize the parallelization of the cluster. Think about the extreme case - a single threaded program with zero shuffle.
In C++11 and beyond, you can use the back
member function:
char ch = myStr.back();
In C++03, std::string::back
is not available due to an oversight, but you can get around this by dereferencing the reverse_iterator
you get back from rbegin
:
char ch = *myStr.rbegin();
In both cases, be careful to make sure the string actually has at least one character in it! Otherwise, you'll get undefined behavior, which is a Bad Thing.
Hope this helps!
So, it will depend on the test cases that you want it to handle.
function isNumeric(number) {
return !isNaN(parseFloat(number)) && !isNaN(+number);
}
What I was looking for was regular types of numbers in javascript.
0, 1 , -1, 1.1 , -1.1 , 1E1 , -1E1 , 1e1 , -1e1, 0.1e10, -0.1.e10 , 0xAF1 , 0o172, Math.PI, Number.NEGATIVE_INFINITY, Number.POSITIVE_INFINITY
And also they're representations as strings:
'0', '1', '-1', '1.1', '-1.1', '1E1', '-1E1', '1e1', '-1e1', '0.1e10', '-0.1.e10', '0xAF1', '0o172'
I did want to leave out and not mark them as numeric
'', ' ', [], {}, null, undefined, NaN
As of today, all other answers seemed to failed one of these test cases.

You can break the inline svg code with back-slash "\"
Tested with the code below in Chrome 54 and Firefox 50

and it works (at least in Chrome 54 & Firefox 50 ==> usage in NWjs & Electron guarenteed)
(question) Don't you get that info in
select * from pg_user;
or using the view pg_stat_activity:
select * from pg_stat_activity;
Added:
the view says:
One row per server process, showing database OID, database name, process ID, user OID, user name, current query, query's waiting status, time at which the current query began execution, time at which the process was started, and client's address and port number. The columns that report data on the current query are available unless the parameter stats_command_string has been turned off. Furthermore, these columns are only visible if the user examining the view is a superuser or the same as the user owning the process being reported on.
can't you filter and get that information? that will be the current users on the Database, you can use began execution time to get all queries from last 5 minutes for example...
something like that.
from tkinter import *
window = tk()
window.geometry("300x300")
def close_window ():
window.destroy()
button = Button ( text = "Good-bye", command = close_window)
button.pack()
window.mainloop()
Here's a way to do this in SQL Server 2005 and later without using the deprecated syslogins view:
IF NOT EXISTS
(SELECT name
FROM master.sys.server_principals
WHERE name = 'LoginName')
BEGIN
CREATE LOGIN [LoginName] WITH PASSWORD = N'password'
END
The server_principals view is used instead of sql_logins because the latter doesn't list Windows logins.
If you need to check for the existence of a user in a particular database before creating them, then you can do this:
USE your_db_name
IF NOT EXISTS
(SELECT name
FROM sys.database_principals
WHERE name = 'Bob')
BEGIN
CREATE USER [Bob] FOR LOGIN [Bob]
END
Set decoding to true
Your decoding is not set to true. If you don't have access to set the source to true. The code below will fix it for you.
$WorkingArray = json_decode(json_encode($data),true);
Flexbox? You can use flexbox.
.box {_x000D_
display: -ms-flexbox;_x000D_
display: -webkit-flex;_x000D_
display: flex;_x000D_
_x000D_
-webkit-justify-content: center;_x000D_
justify-content: center;_x000D_
_x000D_
}_x000D_
_x000D_
.box div {_x000D_
border:1px solid grey;_x000D_
flex: 0 1 auto;_x000D_
align-self: auto;_x000D_
background: grey;_x000D_
}
_x000D_
<div class="box">_x000D_
<div class="A">I'm horizontally centered.</div>_x000D_
</div>
_x000D_
It seem like your Resort
method doesn't declare a compareTo
method. This method typically belongs to the Comparable
interface. Make sure your class implements it.
Additionally, the compareTo
method is typically implemented as accepting an argument of the same type as the object the method gets invoked on. As such, you shouldn't be passing a String
argument, but rather a Resort
.
Alternatively, you can compare the names of the resorts. For example
if (resortList[mid].getResortName().compareTo(resortName)>0)
I want to extend Olcay's nice answer. His approach is good, your login page controller should be like this to put the referrer url into session:
@RequestMapping(value = "/login", method = RequestMethod.GET)
public String loginPage(HttpServletRequest request, Model model) {
String referrer = request.getHeader("Referer");
request.getSession().setAttribute("url_prior_login", referrer);
// some other stuff
return "login";
}
And you should extend SavedRequestAwareAuthenticationSuccessHandler
and override its onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication)
method. Something like this:
public class MyCustomLoginSuccessHandler extends SavedRequestAwareAuthenticationSuccessHandler {
public MyCustomLoginSuccessHandler(String defaultTargetUrl) {
setDefaultTargetUrl(defaultTargetUrl);
}
@Override
public void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) throws ServletException, IOException {
HttpSession session = request.getSession();
if (session != null) {
String redirectUrl = (String) session.getAttribute("url_prior_login");
if (redirectUrl != null) {
// we do not forget to clean this attribute from session
session.removeAttribute("url_prior_login");
// then we redirect
getRedirectStrategy().sendRedirect(request, response, redirectUrl);
} else {
super.onAuthenticationSuccess(request, response, authentication);
}
} else {
super.onAuthenticationSuccess(request, response, authentication);
}
}
}
Then, in your spring configuration, you should define this custom class as a bean and use it on your security configuration. If you are using annotation config, it should look like this (the class you extend from WebSecurityConfigurerAdapter
):
@Bean
public AuthenticationSuccessHandler successHandler() {
return new MyCustomLoginSuccessHandler("/yourdefaultsuccessurl");
}
In configure
method:
@Override
protected void configure(HttpSecurity http) throws Exception {
http
// bla bla
.formLogin()
.loginPage("/login")
.usernameParameter("username")
.passwordParameter("password")
.successHandler(successHandler())
.permitAll()
// etc etc
;
}
Try reinterpret_cast
unsigned char *foo();
std::string str;
str.append(reinterpret_cast<const char*>(foo()));
Table cells don't respect margin, but you could use transparent borders instead:
div {
display: table-cell;
border: 5px solid transparent;
}
Note: you can't use percentages here... :(
If you want to get the DATE and not DATETIME format:
df["id_date"] = pd.to_datetime(df["id_date"]).dt.date
If your whole expression is case insensitive, you can just specify the CASE_INSENSITIVE
flag:
Pattern.compile(regexp, Pattern.CASE_INSENSITIVE)
Use the following script tag in your jsp/js file:
<script src="http://code.jquery.com/jquery-1.9.0.js"></script>
<script src="http://code.jquery.com/jquery-migrate-1.2.1.js"></script>
this will work for sure.
In java you don't check if a key is pressed, instead you listen to KeyEvent
s.
The right way to achieve your goal is to register a KeyEventDispatcher
, and implement it to maintain the state of the desired key:
import java.awt.KeyEventDispatcher;
import java.awt.KeyboardFocusManager;
import java.awt.event.KeyEvent;
public class IsKeyPressed {
private static volatile boolean wPressed = false;
public static boolean isWPressed() {
synchronized (IsKeyPressed.class) {
return wPressed;
}
}
public static void main(String[] args) {
KeyboardFocusManager.getCurrentKeyboardFocusManager().addKeyEventDispatcher(new KeyEventDispatcher() {
@Override
public boolean dispatchKeyEvent(KeyEvent ke) {
synchronized (IsKeyPressed.class) {
switch (ke.getID()) {
case KeyEvent.KEY_PRESSED:
if (ke.getKeyCode() == KeyEvent.VK_W) {
wPressed = true;
}
break;
case KeyEvent.KEY_RELEASED:
if (ke.getKeyCode() == KeyEvent.VK_W) {
wPressed = false;
}
break;
}
return false;
}
}
});
}
}
Then you can always use:
if (IsKeyPressed.isWPressed()) {
// do your thing.
}
You can, of course, use same method to implement isPressing("<some key>")
with a map of keys and their state wrapped inside IsKeyPressed
.

You can try getting a list from the map object by just iterating each item in the object and store it in a different variable.
a = map(chr, [66, 53, 0, 94])
b = [item for item in a]
print(b)
>>>['B', '5', '\x00', '^']
or use this header library and write:
// |notEqaul|less|lessEqual|greater|greaterEqual
if(sweet::equal(valueA,valueB))
and don't care about signed/unsigned or different sizes
You can combine the benefits of generators with the certainty of len()
, by creating your own iterable object:
class MyIterable(object):
def __init__(self, n):
self.n = n
def __len__(self):
return self.n
def __iter__(self):
self._gen = self._generator()
return self
def _generator(self):
# Put your generator code here
i = 0
while i < self.n:
yield i
i += 1
def next(self):
return next(self._gen)
mi = MyIterable(100)
print len(mi)
for i in mi:
print i,
This is basically a simple implementation of xrange
, which returns an object you can take the len of, but doesn't create an explicit list.
You want the file module. To create a directory, you need to specify the option state=directory
:

You could use the INDIRECT function. This takes a string and converts it into a range
More info here
=INDIRECT("K"&A2)
But it's preferable to use INDEX as it is less volatile.
=INDEX(K:K,A2)
This returns a value or the reference to a value from within a table or range

Put either function into cell B2 and fill down.
In my case (Oracle), it's WHERE REGEXP_LIKE(column, 'regex.*')
. See here:
SQL Function
Description
REGEXP_LIKE
This function searches a character column for a pattern. Use this function in the WHERE clause of a query to return rows matching the regular expression you specify.
...
REGEXP_REPLACE
This function searches for a pattern in a character column and replaces each occurrence of that pattern with the pattern you specify.
...
REGEXP_INSTR
This function searches a string for a given occurrence of a regular expression pattern. You specify which occurrence you want to find and the start position to search from. This function returns an integer indicating the position in the string where the match is found.
...
REGEXP_SUBSTR
This function returns the actual substring matching the regular expression pattern you specify.
(Of course, REGEXP_LIKE only matches queries containing the search string, so if you want a complete match, you'll have to use '^$'
for a beginning (^
) and end ($
) match, e.g.: '^regex.*$'
.)
This approach works for both files and jars:
Class clazz = Class.forName(nameOfClassYouWant);
URL resourceUrl = clazz.getResource("/" + clazz.getCanonicalName().replace(".", "/") + ".class");
InputStream classStream = resourceUrl.openStream(); // load the bytecode, if you wish
This expands on the answer by Denis Bubnov.
I used this to find child values of array elements—namely if there was a anchor field in paragraphs on a Drupal 8 site to build a table of contents.
{% set count = 0 %}
{% for anchor in items %}
{% if anchor.content['#paragraph'].field_anchor_link.0.value %}
{% set count = count + 1 %}
{% endif %}
{% endfor %}
{% if count > 0 %}
--- build the toc here --
{% endif %}
Just to add to the list of options. You can also grab the object from the database, and use an auto mapping tool like Auto Mapper to update the parts of the record you want to change..

There are a bunch of different reasons for the "Too Many Connections" error.
Check out this FAQ page on MySQL.com: http://dev.mysql.com/doc/refman/5.5/en/too-many-connections.html
Check your my.cnf file for "max_connections". If none exist try:
[mysqld]
set-variable=max_connections=250
However the default is 151, so you should be okay.
If you are on a shared host, it might be that other users are taking up too many connections.
Other problems to look out for is the use of persistent connections and running out of diskspace.
This worked for me. Repeatedly calls a function updating the graph every time.
import matplotlib.pyplot as plt
import matplotlib.animation as anim
def plot_cont(fun, xmax):
y = []
fig = plt.figure()
ax = fig.add_subplot(1,1,1)
def update(i):
yi = fun()
y.append(yi)
x = range(len(y))
ax.clear()
ax.plot(x, y)
print i, ': ', yi
a = anim.FuncAnimation(fig, update, frames=xmax, repeat=False)
plt.show()
"fun" is a function that returns an integer. FuncAnimation will repeatedly call "update", it will do that "xmax" times.
You can see collation settings for each table like the following code:
SELECT t.name TableName, c.name ColumnName, collation_name
FROM sys.columns c
INNER JOIN sys.tables t on c.object_id = t.object_id where t.name = 'name of table';
The 1. usecase which comes into my mind, is an api
call, which should't go into the render, because it will run for each
state change. And the API call should be only performed on special state change, and not on every render.
changeSearchParams = (params) => {
this.setState({ params }, this.performSearch)
}
performSearch = () => {
API.search(this.state.params, (result) => {
this.setState({ result })
});
}
Hence for any state change, an action can be performed in the render methods body.
Very bad practice, because the render
-method should be pure, it means no actions, state changes, api calls, should be performed, just composite your view and return it. Actions should be performed on some events only. Render is not an event, but componentDidMount
for example.
You can run a command as admin using
sudo <command>
You can also switch to root and every command will be run as root

I've created the following example based on Scott Wales' answer. I've tested it in macOS High Sierra 10.13.3 running go
version go1.10 darwin/amd64
.
(1) Code for library.hpp

std::cout << "[c++] Foo::Foo(" << m_value << ")" << std::endl;
}
Foo::~Foo() { std::cout << "[c++] Foo::~Foo(" << m_value << ")" << std::endl; }
int Foo::value() const {

std::cout << "[c++ bridge] LIB_NewFoo(" << value << ") will return pointer "
<< foo << std::endl;
return foo;
}
// Utility function local to the bridge's implementation
Foo* AsFoo(void* foo) { return reinterpret_cast<Foo*>(foo); }
void LIB_DestroyFoo(void* foo) {
std::cout << "[c++ bridge] LIB_DestroyFoo(" << foo << ")" << std::endl;
AsFoo(foo)->~Foo();
}
int LIB_FooValue(void* foo) {
std::cout << "[c++ bridge] LIB_FooValue(" << foo << ")" << std::endl;
return AsFoo(foo)->value();
}
(5) Finally, library.go
, the go program calling the C++ API.
package main
// #cgo LDFLAGS: -L. -llibrary
// #include "library-bridge.h"
import "C"
import "unsafe"
import "fmt"
type Foo struct {
ptr unsafe.Pointer
}
func NewFoo(value int) Foo {
var foo Foo
foo.ptr = C.LIB_NewFoo(C.int(value))
return foo
}
func (foo Foo) Free() {
C.LIB_DestroyFoo(foo.ptr)
}
func (foo Foo) value() int {
return int(C.LIB_FooValue(foo.ptr))
}
func main() {
foo := NewFoo(42)
defer foo.Free() // The Go analog to C++'s RAII
fmt.Println("[go]", foo.value())
}
Using the following Makefile
liblibrary.so: library.cpp library-bridge.cpp
clang++ -o liblibrary.so library.cpp library-bridge.cpp \
-std=c++17 -O3 -Wall -Wextra -fPIC -shared
I can run the example program as follows:
$ make
clang++ -o liblibrary.so library.cpp library-bridge.cpp \
-std=c++17 -O3 -Wall -Wextra -fPIC -shared
$ go run library.go
[c++ bridge] LIB_NewFoo(42)
[c++] Foo::Foo(42)
[c++ bridge] LIB_NewFoo(42) will return pointer 0x42002e0
[c++ bridge] LIB_FooValue(0x42002e0)
[c++] Foo::value() is 42
[go] 42
[c++ bridge] LIB_DestroyFoo(0x42002e0)
[c++] Foo::~Foo(42)
Important
The comments above import "C"
in the go
program are NOT OPTIONAL. You must put them exactly as shown so that cgo
knows which header and library to load, in this case:
// #cgo LDFLAGS: -L. -llibrary
// #include "library-bridge.h"
import "C"
Some time when we use Environ()
function we may get the Library or property not found error. Use VBA.Environ()
or VBA.Environ$()
to avoid the error.
This will remove all listeners from children but will be slow for large pages. Brutally simple to write.

Microsoft Core Library, ie they are at the heart of everything.
There is a more "massaged" explanation you may prefer:
"When Microsoft first started working on the .NET Framework, MSCorLib.dll was an acronym for Microsoft Common Object Runtime Library. Once ECMA started to standardize the CLR and parts of the FCL, MSCorLib.dll officially became the acronym for Multilanguage Standard Common Object Runtime Library."
From http://weblogs.asp.net/mreynolds/archive/2004/01/31/65551.aspx
Around 1999, to my personal memory, .Net was known as "COOL", so I am a little suspicious of this derivation. I never heard it called "COR", which is a silly-sounding name to a native English speaker.
Try following query:-
SELECT table1.id
FROM table1
where table1.id
NOT IN (SELECT user_one
FROM Table2
UNION
SELECT user_two
FROM Table2)
Hope this helps you.
What about to use the specialized version of the "bind" command "one". Once the event handler executes the first time, it’s automatically removed as an event handler.
$(window).one("beforeunload", BeforeUnload);
Idk if you guys solved it but I recommend another way to do it, and it works :)
ServiceUtil = ig.Class.extend({
base_url : 'someurl',
sendRequest: function(request)
{
var url = this.base_url + request;
var requestVar = new XMLHttpRequest();
dataGet = false;
$.ajax({
url: url,
async: false,
type: "get",
success: function(data){
ServiceUtil.objDataReturned = data;
}
});
return ServiceUtil.objDataReturned;
}
})
So the main idea here is that, by adding async: false, then you make everything waits until the data is retrieved. Then you assign it to a static variable of the class, and everything magically works :)

Piping output to xargs
will concatenate each line of output to a single line with spaces:
grep pattern file | xargs
Or any command, eg. ls | xargs
. The default limit of xargs
output is ~4096 characters, but can be increased with eg. xargs -s 8192
.
Just an FYI for answer Replacing characters in Ant property - if you are trying to use this inside of a maven execution, you can't reference maven variables directly. You will need something like this:
...
<target>
<property name="propATemp" value="${propA}"/>
<loadresource property="propB">
<propertyresource name="propATemp" />
...
The easiest way I found was with this command:
git config --global credential.https://github.com.username <your_username>
This works on a site by site basis and modifies your global git config.
To see the changes, use:
git config --global --edit
Another alternative: you can check if an item is in a list with if item in list:
, but this is order O(n). If you are dealing with big lists of items and all you need to know is whether something is a member of your list, you can convert the list to a set first and take advantage of constant time set lookup:
my_set = set(my_list)
if item in my_set: # much faster on average than using a list
# do something
Not going to be the correct solution in every case, but for some cases this might give you better performance.
Note that creating the set with set(my_list)
is also O(n), so if you only need to do this once then it isn't any faster to do it this way. If you need to repeatedly check membership though, then this will be O(1) for every lookup after that initial set creation.
As a rule of thumb:
private
: class scope.default
(or package-private
): package scope.protected
: package scope + child
(like package, but we can subclass it from different packages). The protected modifier always keeps the "parent-child" relationship.public
: everywhere.As a result, if we divide access right into three rights:
then we have this simple table:
+—-———————————————+————————————+———————————+
| | Same | Different |
| | Package | Packages |
+—————————————————+————————————+———————————+
| private | D | |
+—————————————————+————————————+———————————+
| package-private | | |
| (no modifier) | D R I | |
+—————————————————+————————————+———————————+
| protected | D R I | I |
+—————————————————+————————————+———————————+
| public | D R I | R I |
+—————————————————+————————————+———————————+
Why do you use Restrictions.like(...
)?
You should use Restrictions.eq(...)
.
Note you can also use .le
, .lt
, .ge
, .gt
on date objects as comparison operators. LIKE
operator is not appropriate for this case since LIKE
is useful when you want to match results according to partial content of a column.
Please see http://www.sql-tutorial.net/SQL-LIKE.asp for the reference.
For example if you have a name column with some people's full name, you can do where name like 'robert %'
so that you will return all entries with name starting with 'robert '
(%
can replace any character).
In your case you know the full content of the date you're trying to match so you shouldn't use LIKE
but equality. I guess Hibernate doesn't give you any exception in this case, but anyway you will probably have the same problem with the Restrictions.eq(...)
.
Your date object you got with the code:
SimpleDateFormat formatter = new SimpleDateFormat("dd-MM-YYYY");
String myDate = "17-04-2011";
Date date = formatter.parse(myDate);
This date object is equals to the 17-04-2011 at 0h, 0 minutes, 0 seconds and 0 nanoseconds.
This means that your entries in database must have exactly that date. What i mean is that if your database entry has a date "17-April-2011 19:20:23.707000000", then it won't be retrieved because you just ask for that date: "17-April-2011 00:00:00.0000000000".
If you want to retrieve all entries of your database from a given day, you will have to use the following code:
SimpleDateFormat formatter = new SimpleDateFormat("dd-MM-YYYY");
String myDate = "17-04-2011";
// Create date 17-04-2011 - 00h00
Date minDate = formatter.parse(myDate);
// Create date 18-04-2011 - 00h00
// -> We take the 1st date and add it 1 day in millisecond thanks to a useful and not so known class
Date maxDate = new Date(minDate.getTime() + TimeUnit.DAYS.toMillis(1));
Conjunction and = Restrictions.conjunction();
// The order date must be >= 17-04-2011 - 00h00
and.add( Restrictions.ge("orderDate", minDate) );
// And the order date must be < 18-04-2011 - 00h00
and.add( Restrictions.lt("orderDate", maxDate) );
If you have a hardcoded image URL, for example: http://example.com/image.jpg you can use php to add headers to your image.
First you will have to make apache process your jpg as php. See here: Is it possible to execute PHP with extension file.php.jpg?
Load the image (imagecreatefromjpeg) from file then add the headers from previous answers. Use php function header to add the headers.
Then output the image with the imagejpeg function.
Please notice that it's very insecure to let php process jpg images. Also please be aware I haven't tested this solution so it is up to you to make it work.
The answer given by P????? creates a nullable bool, not a bool, which may be fine for you. For example in C# it would create: bool? AdminApproved
not bool AdminApproved
.
If you need to create a bool (defaulting to false):
ALTER TABLE person
ADD AdminApproved BIT
DEFAULT 0 NOT NULL;
Thread
When you start an app, a process is created to execute the code. To efficiently use computing resource, threads can be started within the process so that multiple tasks can be executed at the time. So threads allow you to build efficient apps by utilizing cpu efficiently without idle time.
In Android, all components execute on a single called main thread. Android system queue tasks and execute them one by one on the main thread. When long running tasks are executed, app become unresponsive.
To prevent this, you can create worker threads and run background or long running tasks.
Handler
Since android uses single thread model, UI components are created non-thread safe meaning only the thread it created should access them that means UI component should be updated on main thread only. As UI component run on the main thread, tasks which run on worker threads can not modify UI components. This is where Handler comes into picture. Handler with the help of Looper can connect to new thread or existing thread and run code it contains on the connected thread.
Handler makes it possible for inter thread communication. Using Handler, background thread can send results to it and the handler which is connected to main thread can update the UI components on the main thread.
AsyncTask
AsyncTask provided by android uses both thread and handler to make running simple tasks in the background and updating results from background thread to main thread easy.
Please see android thread, handler, asynctask and thread pools for examples.
Actually emberjs
supports two-way binding, which is one of the most powerful feature for a javascript MVC framework. You can check it out where it mentioning binding
in its user guide.
for emberjs, to create two way binding is by creating a new property with the string Binding at the end, then specifying a path from the global scope:
App.wife = Ember.Object.create({
householdIncome: 80000
});
App.husband = Ember.Object.create({
householdIncomeBinding: 'App.wife.householdIncome'
});
App.husband.get('householdIncome'); // 80000
// Someone gets raise.
App.husband.set('householdIncome', 90000);
App.wife.get('householdIncome'); // 90000
Note that bindings don't update immediately. Ember waits until all of your application code has finished running before synchronizing changes, so you can change a bound property as many times as you'd like without worrying about the overhead of syncing bindings when values are transient.

I noticed one answer that was similar, but in my case I used the IIS Configured Editor to find the section I wanted to "unlock".
Then I copied the path and used it in my automation to unlock it prior to changing the sections I wanted to edit.

. "$($env:windir)\system32\inetsrv\appcmd" unlock config -section:system.webServer/security/authentication/anonymousAuthentication
Another difference is that Sublime text is a closed source project, while Atom source code is/will be publicly available --although Github does not plan to release it as a real open source project. They want to give access to the code, without opening it to contributions.
Github made the code public: http://blog.atom.io/2014/05/06/atom-is-now-open-source.html
If you have less than 4 rows, you can use the head
function ( head(data, 4)
or head(data, n=4)
) and it works like a charm. But, assume we have the following dataset with 15 rows

>data

As mentioned already, the contents are stored at the server. However the session is identified by a session-id, which is stored at the client and send with each request. Usually the session-id is stored in a cookie, but it can also be appended to urls. (That's the PHPSESSID
query-parameter you some times see)
This also would work:
export LD_LIBRARY_PATH=/usr/lib/hadoop/lib/native
Knowing the error message would be rather valuable. It is meant to provide info, even though it doesn't make any sense to you it does to us. Being forced to guess, I'd say that the DLL is a 32-bit DirectX filter. In which case this should be the proper course of action:
cd c:\windows\syswow64
move ..\system32\dllname.ax .
regsvr32.exe dllname.ax
This must be run at an elevated command prompt so that UAC cannot stop the registry access that's required. Ask more questions about this at superuser.com
It's just a syntax error. You just have to replace j+3
by j=j+3
or j+=3
.
You can restart an existing container after it exited and your changes are still there.
docker start `docker ps -q -l` # restart it in the background
docker attach `docker ps -q -l` # reattach the terminal & stdin
Your variable size
is declared as: float size;
You can't use a floating point variable as the size of an array - it needs to be an integer value.
You could cast it to convert to an integer:
float *temp = new float[(int)size];
Your other problem is likely because you're writing outside of the bounds of the array:
float *temp = new float[size];
//Getting input from the user
for (int x = 1; x <= size; x++){
cout << "Enter temperature " << x << ": ";
// cin >> temp[x];
// This should be:
cin >> temp[x - 1];
}
Arrays are zero based in C++, so this is going to write beyond the end and never write the first element in your original code.

To answer the non-reproducability aspect of the question - Firefox automatically imports intermediate certificates into its certificate store. So if you've previously visited a site which has used the same Intermediate Certificate using a correctly configured certificate chain then Firefox will store that Certificate so you will not see the problem when you visit a site that has an incorrectly configured chain using the same Intermediate certificate.
You can check this in Firefox's Certificate Manager (Options->Privacy&Security->View Certificates...) where you can see all stored certificates. Under the 'Security Device' Column you can check where a certificate has come from - automatically/manually imported certificates will appear as from 'Software Security Device' as opposed to the 'Builtin Object Token', which are the default set installed with Firefox. You can delete/Distrust any specific certificates and test again.
change your code to:
function ChangePurpose(Vid, PurId) {
var Success = false;
$.ajax({
type: "POST",
url: "CHService.asmx/SavePurpose",
dataType: "text",
async: false,
data: JSON.stringify({ Vid: Vid, PurpId: PurId }),
contentType: "application/json; charset=utf-8",
success: function (data) {
Success = true;
},
error: function (textStatus, errorThrown) {
Success = false;
}
});
//done after here
return Success;
}
You can only return the values from a synchronous
function. Otherwise you will have to make a callback
.
So I just added async:false,
to your ajax call
Update:
jquery ajax calls are asynchronous by default. So success & error functions will be called when the ajax load is complete. But your return statement will be executed just after the ajax call is started.
A better approach will be:
// callbackfn is the pointer to any function that needs to be called
function ChangePurpose(Vid, PurId, callbackfn) {
var Success = false;
$.ajax({
type: "POST",
url: "CHService.asmx/SavePurpose",
dataType: "text",
data: JSON.stringify({ Vid: Vid, PurpId: PurId }),
contentType: "application/json; charset=utf-8",
success: function (data) {
callbackfn(data)
},
error: function (textStatus, errorThrown) {
callbackfn("Error getting the data")
}
});
}
function Callback(data)
{
alert(data);
}
and call the ajax as:
// Callback is the callback-function that needs to be called when asynchronous call is complete
ChangePurpose(Vid, PurId, Callback);
..
NSString *date = @"2009-05-11"
NSString *nowDate = [[[NSDate date]description]substringToIndex: 10];
if([date isEqualToString: nowDate])
{

}
I had the same exact question and after reading these responses mistakenly decided it wasn't possible to get the exact resulting query. I was wrong.
Solution:
Open Activity Monitor
in SQL Server Management Studio
, narrow the processes section to the login username, database or application name that your application is using in the connection string. When the call is made to the db refresh Activity Monitor
. When you see the process, right click on it and View Details
.
Note, this may not be a viable option for a busy db. But you should be able to narrow the result considerably using these steps.
You can do it like this:
In your main view controller:
func showModal() {
let modalViewController = ModalViewController()
modalViewController.modalPresentationStyle = .overCurrentContext
presentViewController(modalViewController, animated: true, completion: nil)
}
In your modal view controller:
class ModalViewController: UIViewController {
override func viewDidLoad() {
view.backgroundColor = UIColor.clearColor()
view.opaque = false
}
}
If you are working with a storyboard:
Just add a Storyboard Segue with Kind
set to Present Modally
to your modal view controller and on this view controller set the following values:
As Crashalot pointed out in his comment: Make sure the segue only uses Default
for both Presentation
and Transition
. Using Current Context
for Presentation
makes the modal turn black instead of remaining transparent.
When we use CommandObj.Parameter.Add()
it takes 2 parameters, the first is procedure parameter and the second is its data type, while .AddWithValue()
takes 2 parameters, the first is procedure parameter and the second is the data variable
CommandObj.Parameter.Add("@ID",SqlDbType.Int).Value=textBox1.Text;
for .AddWithValue
CommandObj.Parameter.AddWitheValue("@ID",textBox1.Text);
where ID
is the parameter of stored procedure which data type is Int
To follow 3XX redirects and print response codes for all requests:
