I was facing the same issue and below step removed all these errors :
Use the start command to prevent the batch file from waiting for the program. Just remember to put a empty double quote in front of the program you want to run after "Start". For example, if you want to run Visual Studio 2012 from a batch command:
Start "" "C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\devenv.exe"
notice the double quote after start.
You can refer in this line - Difference between ASP.NET Core (.NET Core) and ASP.NET Core (.NET Framework)
Xamarin is not a debate at all. When you want to build mobile (iOS, Android, and Windows Mobile) apps using C#, Xamarin is your only choice.
The .NET Framework supports Windows and Web applications. Today, you can use Windows Forms, WPF, and UWP to build Windows applications in .NET Framework. ASP.NET MVC is used to build Web applications in .NET Framework.
.NET Core is the new open-source and cross-platform framework to build applications for all operating system including Windows, Mac, and Linux. .NET Core supports UWP and ASP.NET Core only. UWP is used to build Windows 10 targets Windows and mobile applications. ASP.NET Core is used to build browser based web applications.

Yes, we can use jQuery in ReactJs. Here I will tell how we can use it using npm.
step 1: Go to your project folder where the package.json
file is present via using terminal using cd command.
step 2: Write the following command to install jquery using npm : npm install jquery --save
step 3: Now, import $
from jquery
into your jsx file where you need to use.
Example:
write the below in index.jsx
import React from 'react';
import ReactDOM from 'react-dom';
import $ from 'jquery';
// react code here
$("button").click(function(){
$.get("demo_test.asp", function(data, status){
alert("Data: " + data + "\nStatus: " + status);
});
});
// react code here
write the below in index.html
<!DOCTYPE html>
<html>
<head>
<script src="index.jsx"></script>
<!-- other scripting files -->
</head>
<body>
<!-- other useful tags -->
<div id="div1">
<h2>Let jQuery AJAX Change This Text</h2>
</div>
<button>Get External Content</button>
</body>
</html>
you can use
getElementsByClassName
suppose you have some elements and applied a class name 'test', so, you can get elements like as following
var tests = document.getElementsByClassName('test');
its returns an instance NodeList
, or its superset: HTMLCollection
(FF).
I'll edit my previous answer based on further info supplied. You can clearely ping the remote computer as you can use terminal services.
I've a feeling that port 1433 is being blocked by a firewall, hence your trouble. See TCP Ports Needed for Communication to SQL Server Through a Firewall by Microsoft.
Try using this application to ping your servers ip address and port 1433.
tcping your.server.ip.address 1433
And see if you get a "Port is open" response from tcping.
Ok, next to try is to check SQL Server. RDP onto the SQL Server computer. Start SSMS. Connect to the database. In object explorer (usually docked on the left) right click on the server and click properties.

Goto the Connections settings and make sure "Allow remote connections to this server" is ticket.
You can use the "Join" function to create a single string out of the array of labels, like this:
=Join(Parameters!Product.Label, ",")
Well, Mr.ajb has resolved and pointed out the error in your code.
Coming to the second part of the code, that is, converting a string with letters to decimal integer below is code for that,
import java.util.Scanner;
public class HexaToDecimal
{
int number;
void getValue()
{
Scanner sc = new Scanner(System.in);
System.out.println("Please enter hexadecimal to convert: ");
number = Integer.parseInt(sc.nextLine(), 16);
sc.close();
}
void toConvert()
{
String decimal = Integer.toString(number);
System.out.println("The Decimal value is : " + decimal);
}
public static void main(String[] args)
{
HexaToDecimal htd = new HexaToDecimal();
htd.getValue();
htd.toConvert();
}
}
You can refer example on hexadecimal to decimal for more information.
I've used bootstrap header classes ("h1", "h2", etc.) for this. This way you get all the style benefits without using the actual tags. Here is an example:
<div class="h3"><span class="glyphicon glyphicon-tags" aria-hidden="true"></span></div>
To get a more precise (and user friendly) information about connection type. You can use this code (derived from a @hide method in TelephonyManager.java).
This method returns a String describing the current connection type.
i.e. one of : "WIFI" , "2G" , "3G" , "4G" , "5G" , "-" (not connected) or "?" (unknown)
Remark: This code requires API 25+, but you can easily support older versions by using int instead of const. (See comments in code).
public static String getNetworkClass(Context context) {
ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo info = cm.getActiveNetworkInfo();
if (info == null || !info.isConnected())
return "-"; // not connected
if (info.getType() == ConnectivityManager.TYPE_WIFI)
return "WIFI";
if (info.getType() == ConnectivityManager.TYPE_MOBILE) {
int networkType = info.getSubtype();
switch (networkType) {
case TelephonyManager.NETWORK_TYPE_GPRS:
case TelephonyManager.NETWORK_TYPE_EDGE:
case TelephonyManager.NETWORK_TYPE_CDMA:
case TelephonyManager.NETWORK_TYPE_1xRTT:
case TelephonyManager.NETWORK_TYPE_IDEN: // api< 8: replace by 11
case TelephonyManager.NETWORK_TYPE_GSM: // api<25: replace by 16
return "2G";
case TelephonyManager.NETWORK_TYPE_UMTS:
case TelephonyManager.NETWORK_TYPE_EVDO_0:
case TelephonyManager.NETWORK_TYPE_EVDO_A:
case TelephonyManager.NETWORK_TYPE_HSDPA:
case TelephonyManager.NETWORK_TYPE_HSUPA:
case TelephonyManager.NETWORK_TYPE_HSPA:
case TelephonyManager.NETWORK_TYPE_EVDO_B: // api< 9: replace by 12
case TelephonyManager.NETWORK_TYPE_EHRPD: // api<11: replace by 14
case TelephonyManager.NETWORK_TYPE_HSPAP: // api<13: replace by 15
case TelephonyManager.NETWORK_TYPE_TD_SCDMA: // api<25: replace by 17
return "3G";
case TelephonyManager.NETWORK_TYPE_LTE: // api<11: replace by 13
case TelephonyManager.NETWORK_TYPE_IWLAN: // api<25: replace by 18
case 19: // LTE_CA
return "4G";
case TelephonyManager.NETWORK_TYPE_NR: // api<29: replace by 20
return "5G";
default:
return "?";
}
}
return "?";
}
I suggest this discriminative question:
Is the open-source tool necessary in your process of making money?
I just found this extension called beautify in the Market Place and yes, it's another config\settings file. :)
Beautify javascript, JSON, CSS, Sass, and HTML in Visual Studio Code.
VS Code uses js-beautify internally, but it lacks the ability to modify the style you wish to use. This extension enables running js-beautify in VS Code, AND honouring any .jsbeautifyrc file in the open file's path tree to load your code styling. Run with F1 Beautify (to beautify a selection) or F1 Beautify file.
For help on the settings in the .jsbeautifyrc see Settings.md
Here is the GitHub repository: https://github.com/HookyQR/VSCodeBeautify
After fiddling around for a while, I figured things out, and am posting them here hoping it will help others.
Intuitively, np.where
is like asking "tell me where in this array, entries satisfy a given condition".
>>> a = np.arange(5,10)
>>> np.where(a < 8) # tell me where in a, entries are < 8
(array([0, 1, 2]),) # answer: entries indexed by 0, 1, 2
It can also be used to get entries in array that satisfy the condition:
>>> a[np.where(a < 8)]
array([5, 6, 7]) # selects from a entries 0, 1, 2
When a
is a 2d array, np.where()
returns an array of row idx's, and an array of col idx's:
>>> a = np.arange(4,10).reshape(2,3)
array([[4, 5, 6],
[7, 8, 9]])
>>> np.where(a > 8)
(array(1), array(2))
As in the 1d case, we can use np.where()
to get entries in the 2d array that satisfy the condition:
>>> a[np.where(a > 8)] # selects from a entries 0, 1, 2
array([9])
Note, when a
is 1d, np.where()
still returns an array of row idx's and an array of col idx's, but columns are of length 1, so latter is empty array.
PFX files are PKCS#12 Personal Information Exchange Syntax Standard bundles. They can include arbitrary number of private keys with accompanying X.509 certificates and a certificate authority chain (set certificates).
If you want to extract client certificates, you can use OpenSSL's PKCS12 tool.
openssl pkcs12 -in input.pfx -out mycerts.crt -nokeys -clcerts
The command above will output certificate(s) in PEM format. The ".crt" file extension is handled by both macOS and Window.
You mention ".cer" extension in the question which is conventionally used for the DER encoded files. A binary encoding. Try the ".crt" file first and if it's not accepted, easy to convert from PEM to DER:
openssl x509 -inform pem -in mycerts.crt -outform der -out mycerts.cer
I did it in the following way.

Hope this will help others as I was struggling with it since a long time.
The difference between link
and controller
comes into play when you want to nest directives in your DOM and expose API functions from the parent directive to the nested ones.
From the docs:
Best Practice: use controller when you want to expose an API to other directives. Otherwise use link.
Say you want to have two directives my-form
and my-text-input
and you want my-text-input
directive to appear only inside my-form
and nowhere else.
In that case, you will say while defining the directive my-text-input
that it requires a controller from the parent
DOM element using the require argument, like this: require: '^myForm'
. Now the controller from the parent element will be injected
into the link
function as the fourth argument, following $scope, element, attributes
. You can call functions on that controller and communicate with the parent directive.
Moreover, if such a controller is not found, an error will be raised.
There is no real need to use the link
function if one is defining the controller
since the $scope
is available on the controller
. Moreover, while defining both link
and controller
, one does need to be careful about the order of invocation of the two (controller
is executed before).
However, in keeping with the Angular way, most DOM manipulation and 2-way binding using $watchers
is usually done in the link
function while the API for children and $scope
manipulation is done in the controller
. This is not a hard and fast rule, but doing so will make the code more modular and help in separation of concerns (controller will maintain the directive
state and link
function will maintain the DOM
+ outside bindings).
Note a similar error such as:
standard_init_linux.go:211: exec user process caused "no such file or directory"
can happen if the architecture an image was built for does not match the one of your system. For instance, trying to run an image built for arm64
on a x86_64
machine can generate this error.
if you provide a bad path or a broken link, if the compiler cannot find the image, the picture box would display an X icon on its body.
PictureBox picture = new PictureBox
{
Name = "pictureBox",
Size = new Size(100, 50),
Location = new Point(14, 17),
Image = Image.FromFile(@"c:\Images\test.jpg"),
SizeMode = PictureBoxSizeMode.CenterImage
};
p.Controls.Add(picture);
OR
PictureBox picture = new PictureBox
{
Name = "pictureBox",
Size = new Size(100, 50),
Location = new Point(14, 17),
ImageLocation = @"c:\Images\test.jpg",
SizeMode = PictureBoxSizeMode.CenterImage
};
p.Controls.Add(picture);
i'm not sure where you put images in your folder structure but you can find the path as bellow
picture.ImageLocation = Path.Combine(System.Windows.Forms.Application.StartupPath, "Resources\Images\1.jpg");
A file ending in .o is an object file. The compiler creates an object file for each source file, before linking them together, into the final executable.
You can factor out your common logic to a private method, for example called Initialize
that gets called from both constructors.
Due to the fact that you want to perform argument validation you cannot resort to constructor chaining.
Example:
public Point2D(double x, double y)
{
// Contracts
Initialize(x, y);
}
public Point2D(Point2D point)
{
if (point == null)
throw new ArgumentNullException("point");
// Contracts
Initialize(point.X, point.Y);
}
private void Initialize(double x, double y)
{
X = x;
Y = y;
}
File tree walk ftw
is a recursive way to wall the whole directory tree in the path. More details are here.
NOTE : You can also use fts
that can skip hidden files like .
or ..
or .bashrc
#include <ftw.h>
#include <stdio.h>
#include <sys/stat.h>
#include <string.h>
int list(const char *name, const struct stat *status, int type)
{
if (type == FTW_NS)
{
return 0;
}
if (type == FTW_F)
{
printf("0%3o\t%s\n", status->st_mode&0777, name);
}
if (type == FTW_D && strcmp(".", name) != 0)
{
printf("0%3o\t%s/\n", status->st_mode&0777, name);
}
return 0;
}
int main(int argc, char *argv[])
{
if(argc == 1)
{
ftw(".", list, 1);
}
else
{
ftw(argv[1], list, 1);
}
return 0;
}
output looks like following:

Let us say if you want to match a filename (example: searching for all the *.jpg, *.jpeg, *.png
files.) for a specific needs, use fnmatch
.
#include <ftw.h>
#include <stdio.h>
#include <sys/stat.h>
#include <iostream>
#include <fnmatch.h>
static const char *filters[] = {
"*.jpg", "*.jpeg", "*.png"
};
int list(const char *name, const struct stat *status, int type)
{
if (type == FTW_NS)
{
return 0;
}
if (type == FTW_F)
{
int i;
for (i = 0; i < sizeof(filters) / sizeof(filters[0]); i++) {
/* if the filename matches the filter, */
if (fnmatch(filters[i], name, FNM_CASEFOLD) == 0) {
printf("0%3o\t%s\n", status->st_mode&0777, name);
break;
}
}
}
if (type == FTW_D && strcmp(".", name) != 0)
{
//printf("0%3o\t%s/\n", status->st_mode&0777, name);
}
return 0;
}
int main(int argc, char *argv[])
{
if(argc == 1)
{
ftw(".", list, 1);
}
else
{
ftw(argv[1], list, 1);
}
return 0;
}
You could just go ahead and try :
Console.WriteLine("1. Add account.");
Console.WriteLine("Enter choice: ");
int choice=int.Parse(Console.ReadLine());
That should work for the case statement.
It works with the switch statement and doesn't throw an exception.
var obj = {
"key1" : "k1",
"key2" : "k2",
"key3" : "k3"
};
if ("key1" in obj)
console.log("has key1 in obj");
=========================================================================
To access a child key of another key
var obj = {
"key1": "k1",
"key2": "k2",
"key3": "k3",
"key4": {
"keyF": "kf"
}
};
if ("keyF" in obj.key4)
console.log("has keyF in obj");
The best way to do this is by running the command:
git diff --name-only --cached
When you check the manual you will likely find the following:
--name-only
Show only names of changed files.
And on the example part of the manual:
git diff --cached
Changes between the index and your current HEAD.
Combined together you get the changes between the index and your current HEAD
and Show only names of changed files.
Update: --staged
is also available as an alias for --cached
above in more recent git versions.
The methods in the other answers will not work properly when the yticks are large. The ylabel will either overlap with ticks, be clipped on the left or completely invisible/outside of the figure.
I've modified Hagne's answer so it works with more than 1 column of subplots, for both xlabel and ylabel, and it shifts the plot to keep the ylabel visible in the figure.
def set_shared_ylabel(a, xlabel, ylabel, labelpad = 0.01, figleftpad=0.05):
"""Set a y label shared by multiple axes
Parameters
----------
a: list of axes
ylabel: string
labelpad: float
Sets the padding between ticklabels and axis label"""
f = a[0,0].get_figure()
f.canvas.draw() #sets f.canvas.renderer needed below
# get the center position for all plots
top = a[0,0].get_position().y1
bottom = a[-1,-1].get_position().y0
# get the coordinates of the left side of the tick labels
x0 = 1
x1 = 1
for at_row in a:
at = at_row[0]
at.set_ylabel('') # just to make sure we don't and up with multiple labels
bboxes, _ = at.yaxis.get_ticklabel_extents(f.canvas.renderer)
bboxes = bboxes.inverse_transformed(f.transFigure)
xt = bboxes.x0
if xt < x0:
x0 = xt
x1 = bboxes.x1
tick_label_left = x0
# shrink plot on left to prevent ylabel clipping
# (x1 - tick_label_left) is the x coordinate of right end of tick label,
# basically how much padding is needed to fit tick labels in the figure
# figleftpad is additional padding to fit the ylabel
plt.subplots_adjust(left=(x1 - tick_label_left) + figleftpad)
# set position of label,
# note that (figleftpad-labelpad) refers to the middle of the ylabel
a[-1,-1].set_ylabel(ylabel)
a[-1,-1].yaxis.set_label_coords(figleftpad-labelpad,(bottom + top)/2, transform=f.transFigure)
# set xlabel
y0 = 1
for at in axes[-1]:
at.set_xlabel('') # just to make sure we don't and up with multiple labels
bboxes, _ = at.xaxis.get_ticklabel_extents(fig.canvas.renderer)
bboxes = bboxes.inverse_transformed(fig.transFigure)
yt = bboxes.y0
if yt < y0:
y0 = yt
tick_label_bottom = y0
axes[-1, -1].set_xlabel(xlabel)
axes[-1, -1].xaxis.set_label_coords((left + right) / 2, tick_label_bottom - labelpad, transform=fig.transFigure)
It works for the following example, while Hagne's answer won't draw ylabel (since it's outside of the canvas) and KYC's ylabel overlaps with the tick labels:
import matplotlib.pyplot as plt
import itertools
fig, axes = plt.subplots(3, 4, sharey='row', sharex=True, squeeze=False)
fig.subplots_adjust(hspace=.5)
for i, a in enumerate(itertools.chain(*axes)):
a.plot([0,4**i], [0,4**i])
a.set_title(i)
set_shared_ylabel(axes, 'common X', 'common Y')
plt.show()
Alternatively, if you are fine with colorless axis, I've modified Julian Chen's solution so ylabel won't overlap with tick labels.
Basically, we just have to set ylims of the colorless so it matches the largest ylims of the subplots so the colorless tick labels sets the correct location for the ylabel.
Again, we have to shrink the plot to prevent clipping. Here I've hard coded the amount to shrink, but you can play around to find a number that works for you or calculate it like in the method above.
import matplotlib.pyplot as plt
import itertools
fig, axes = plt.subplots(3, 4, sharey='row', sharex=True, squeeze=False)
fig.subplots_adjust(hspace=.5)
miny = maxy = 0
for i, a in enumerate(itertools.chain(*axes)):
a.plot([0,4**i], [0,4**i])
a.set_title(i)
miny = min(miny, a.get_ylim()[0])
maxy = max(maxy, a.get_ylim()[1])
# add a big axes, hide frame
# set ylim to match the largest range of any subplot
ax_invis = fig.add_subplot(111, frameon=False)
ax_invis.set_ylim([miny, maxy])
# hide tick and tick label of the big axis
plt.tick_params(labelcolor='none', top=False, bottom=False, left=False, right=False)
plt.xlabel("common X")
plt.ylabel("common Y")
# shrink plot to prevent clipping
plt.subplots_adjust(left=0.15)
plt.show()
The string you have here contains a floating point number with a unit. I'd recommend splitting that string into a number and unit part with QString::split()
.
Then use toDouble()
to get a floating point number and round as you want.
One easy way to select random items is to shuffle then slice.
import random
a = [1,2,3,4,5,6,7,8,9]
random.shuffle(a)
print a[:4] # prints 4 random variables
Another option is to transfer stored procedures using SQL Server Integration Services (SSIS). There is a task called Transfer SQL Server Objects Task. You can use the task to transfer the following items:
It's a graphical tutorial for Transfer SQL Server Objects Task.
It seems to me, this is a cross-domain issue since you're not allowed to make a request to a different domain.
You have to find solutions to this problem: - Use a proxy script, running on your server that will forward your request and will handle the response sending it to the browser Or - The service you're making the request should have JSONP support. This is a cross-domain technique. You might want to read this http://en.wikipedia.org/wiki/JSONP
You can use anonymous types for this, i.e.:
var pageObject = (from op in db.ObjectPermissions
join pg in db.Pages on op.ObjectPermissionName equals page.PageName
where pg.PageID == page.PageID
select new { pg, op }).SingleOrDefault();
This will make pageObject into an IEnumerable of an anonymous type so AFAIK you won't be able to pass it around to other methods, however if you're simply obtaining data to play with in the method you're currently in it's perfectly fine. You can also name properties in your anonymous type, i.e.:-
var pageObject = (from op in db.ObjectPermissions
join pg in db.Pages on op.ObjectPermissionName equals page.PageName
where pg.PageID == page.PageID
select new
{
PermissionName = pg,
ObjectPermission = op
}).SingleOrDefault();
This will enable you to say:-
if (pageObject.PermissionName.FooBar == "golden goose") Application.Exit();
For example :-)
If you're installing using --user
(e.g. pip3.6 install --user tmuxp
), it is possible to get the platform-specific user install directory from Python itself using the site
module. For example, on macOS:
$ python2.7 -m site --user-base
/Users/alexp/Library/Python/2.7
By appending /bin
to this, we now have the path where package executables will be installed. We can dynamically populate the PATH in your shell's rc file based on the output; I'm using bash, but with any luck this is portable:
# Add Python bin directories to path
python3.6 -m site &> /dev/null && PATH="$PATH:`python3.6 -m site --user-base`/bin"
python2.7 -m site &> /dev/null && PATH="$PATH:`python2.7 -m site --user-base`/bin"
I use the precise Python versions to reduce the chance of the executables just "disappearing" when Python upgrades a minor version, e.g. from 3.5 to 3.6. They'll disappear because, as can be seen above, the user installation path may include the Python version. So while python3
could point to 3.5 or 3.6, python3.6
will always point to 3.6. This needs to be kept in mind when installing further packages, e.g. use pip3.6
over pip3
.
If you don't mind the idea of packages disappearing, you can use python2
and python3
instead:
# Add Python bin directories to path
# Note: When Python is upgraded, packages may need to be re-installed
# or Python versions managed.
python3 -m site &> /dev/null && PATH="$PATH:`python3 -m site --user-base`/bin"
python2 -m site &> /dev/null && PATH="$PATH:`python2 -m site --user-base`/bin"
Thanks to this question (and answers), I discovered an easy way to get at the exact NumberFormat string for virtually any format that Excel has to offer.
Step 1: In the user interface, set a cell to the NumberFormat you want to use.
In my example, I selected the Chinese (PRC) Currency from the options contained in the "Account Numbers Format" combo box.
Step 2: Expand the Number Format dropdown and select "More Number Formats...".
Step 3: In the Number tab, in Category, click "Custom".
The "Sample" section shows the Chinese (PRC) currency formatting that I applied.
The "Type" input box contains the NumberFormat string that you can use programmatically.
So, in this example, the NumberFormat of my Chinese (PRC) Currency cell is as follows:
_ [$¥-804]* #,##0.00_ ;_ [$¥-804]* -#,##0.00_ ;_ [$¥-804]* "-"??_ ;_ @_
If you do these steps for each NumberFormat that you desire, then the world is yours.
I hope this helps.
Here is my fancy version:
import org.gradle.api.tasks.testing.logging.TestExceptionFormat
import org.gradle.api.tasks.testing.logging.TestLogEvent
tasks.withType(Test) {
testLogging {
// set options for log level LIFECYCLE

// set options for log level DEBUG and INFO
debug {
events TestLogEvent.STARTED,
TestLogEvent.FAILED,
TestLogEvent.PASSED,
TestLogEvent.SKIPPED,
TestLogEvent.STANDARD_ERROR,
TestLogEvent.STANDARD_OUT
exceptionFormat TestExceptionFormat.FULL
}
info.events = debug.events
info.exceptionFormat = debug.exceptionFormat
afterSuite { desc, result ->
if (!desc.parent) { // will match the outermost suite
def output = "Results: ${result.resultType} (${result.testCount} tests, ${result.successfulTestCount} passed, ${result.failedTestCount} failed, ${result.skippedTestCount} skipped)"
def startItem = '| ', endItem = ' |'
def repeatLength = startItem.length() + output.length() + endItem.length()
println('\n' + ('-' * repeatLength) + '\n' + startItem + output + endItem + '\n' + ('-' * repeatLength))
}
}
}
}
For those who could not get DATEADD to work, try this instead: ( NOW( ) - INTERVAL 1 MONTH )
There's also the rotateY
for a real mirror one:
transform: rotateY(180deg);
Which, perhaps, is even more clear and understandable.
EDIT: Doesn't seem to work on Opera though… sadly. But it works fine on Firefox. I guess it might required to implicitly say that we are doing some kind of translate3d
perhaps? Or something like that.
I think this :
@{
Layout = "";
}
is not the same as this :
@{
Layout = null;
}
I use the second and it's working, no _Viewstart included.
How about :
SQL> select * from all_users;
it will return list of all users/schemas, their ID's and date created in DB :
USERNAME USER_ID CREATED
------------------------------ ---------- ---------
SCHEMA1 120 09-SEP-15
SCHEMA2 119 09-SEP-15
SCHEMA3 118 09-SEP-15
$res = ActivityServer::query()->select('channel_id')->where(['id' => $id])->first()->attributesToArray();
I use get()
, it returns an object, I use the attributesToArray()
to change the object attribute to an array.
Install PIL(Python Image Library) :
then:
from PIL import Image
myImage = Image.open("your_image_here");
myImage.show();
You could attach to the KeyDown event and then query the database for that portion of the text that the user has already entered. For example, if the user enters "T", search for things that start with "T". Then, when they enter the next letter, for example "e", search for things in the table that start with "Te".
The available items could be displayed in a "floating" ListBox, for example. You would need to place the ListBox just beneath the TextBox so that they can see the entries available, then remove the ListBox when they're done typing.
I noticed this wasn't working with a static-first-then-reverse-proxy setup. Here's what that looks like:
location @app {
proxy_pass http://localhost:3000$request_uri;
}
location / {
try_files $uri $uri/ @app;
error_page 405 @app;
}
Traverse through the array and find the index of the element which contains a key name
and has the value as the passed param.

This is called string interpolation, and you do it like this:
"The #{animal} #{action} the #{second_animal}"
Important: it will only work when string is inside double quotes (" ").
Example of code that will not work as you expect:
'The #{animal} #{action} the #{second_animal}'
xCode is picky about the GPX file it accepts.
But, in xCode you can create a GPX file with the format it will accept:
And then just change the content of the file to the location you need.
The usual way is to use UPDATE:
UPDATE mytable
SET new_column = <expr containing old_column>
You should be able to do this is a single transaction.
You can use:
<td onclick='javascript:someFunc(this);'></td>
With passing this you can access the DOM object via your function parameters.
Use jQuery dialog to show image, try this code
<html>
<head>
</head>
<body>
<div id="divid">
<img>
</div>
<body>
</html>
<script>
$(document).ready(function(){
$("btn").click(function(){
$("divid").dialog();
});
});
</script>
`
first you have to include jQuery UI at your Page.
What I did was save a reference to the Menu at onCreateOptionsMenu
. This is similar to nir's answer except instead of saving each individual item, I saved the entire menu.
Declare a Menu Menu toolbarMenu;
.
Then in onCreateOptionsMenu
save the menu to your variable
@Override
public boolean onCreateOptionsMenu(Menu menu)
{
getMenuInflater().inflate(R.menu.main_menu, menu);
toolbarMenu = menu;
return true;
}
Now you can access your menu and all of its items anytime you want.
toolbarMenu.getItem(0).setEnabled(false);
Similarly to @brucexin I needed to get OS-level thread identifier (which != thread.get_ident()
) and use something like below not to depend on particular numbers and being amd64-only:
---- 8< ---- (xos.pyx)
"""module xos complements standard module os"""
cdef extern from "<sys/syscall.h>":
long syscall(long number, ...)
const int SYS_gettid
# gettid returns current OS thread identifier.
def gettid():
return syscall(SYS_gettid)
and
---- 8< ---- (test.py)
import pyximport; pyximport.install()
import xos
...
print 'my tid: %d' % xos.gettid()
this depends on Cython though.
You can add the directories for your build process like:
...
<resources>
<resource>
<directory>src/bootstrap</directory>
</resource>
</resources>
...
The src/main/java is the default path which is not needed to be mentioned in the pom.xml
Why not use a combination of the CSS and backend? Use:
style='text-transform:uppercase'
on the TextBox, and in your codebehind use:
Textbox.Value.ToUpper();
You can also easily change your regex on the validator to use lowercase and uppercase letters. That's probably the easier solution than forcing uppercase on them.
The 'best' way to do this would be to set a property on a view object once the update is successful. You can then access this property in the view and inform the user accordingly.
Having said that it would be possible to trigger an alert from the controller code by doing something like this -
public ActionResult ActionName(PostBackData postbackdata)
{
//your DB code
return new JavascriptResult { Script = "alert('Successfully registered');" };
}
You can find further info in this question - How to display "Message box" using MVC3 controller
You can use the col element as specified in HTML 4.0 (link). It works in every browser. You can give it an ID or a class or an inline style. only caveat is that it affects the whole column across all rows. Example:
<table>
<col />
<col width="50" />
<col id="anId" />
<col class="whatever" />
<col style="border:1px solid #000;" />
<tbody>
<tr>
<td>One</td>
<td>Two</td>
<td>Three</td>
<td>Four</td>
<td>Five</td>
</tr>
</tbody>
</table>
First, activate your application at the Facebook Developer center. Applications in development mode are not allowed to retrieve the e-mail field.
If the user is not logged in, you need to login and specify that your application/site will need the e-mail field.
FB.login(
function(response) {
console.log('Welcome!');
},
{scope: 'email'}
);
Then, after the login, or if the user is already logged, retrieve the e-mail using the Facebook API, specifying the field email:
FB.api('/me', {fields: 'name,email'}, (response) => {
console.log(response.name + ', ' + response.email);
console.log('full response: ', response);
});
1) You can wrap your text as CDATA like this:
<mytag>
<![CDATA[Your text goes here. Btw: 5<6 and 6>5]]>
</mytag>
see http://www.w3schools.com/xml/xml_cdata.asp
2) As already someone said: Escape those chars. E.g. like so:
5<6 and 6>5
I faced similar issue yesterday during development. I found out I was using same namespace in 2 different versions of contracts.
We've 2 version of contracts for example version4 and version5. I've copied all the contracts from version4 and renamed all the namespace from version4 to version5. While doing this I forgot to rename the namespace from v4 to v5 in one of the files. Due to namespace conflict, Reference.cs file was empty.
This issue is hard to troubleshoot as you don't get any error message while generating the service reference. To identify this issue I'd manually validate all the new files I'd created. There are other ways to solve this issue. This is the first step you should perform before going for other options.
You will need to build that CREATE TABLE statement from the inputs and then execute it.
A simple example:
declare @cmd nvarchar(1000), @TableName nvarchar(100);
set @TableName = 'NewTable';
set @cmd = 'CREATE TABLE dbo.' + quotename(@TableName, '[') + '(newCol int not null);';
print @cmd;
--exec(@cmd);
Based on different sources I have created Simple Implementation of RecyclerView using a Simple Library.
Add this line in build.gradle
implementation 'com.hereshem.lib:awesomelib:2.0.1'
AddCreate a RecyclerView by adding MyRecyclerView in activity_main.xml with
<com.hereshem.lib.recycler.MyRecyclerView
android:id="@+id/recycler"
app:layoutManager="LinearLayoutManager"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
Now in the MainActivity, Create a ViewHolder by passing the name of Class that needs to bind
public static class EVHolder extends MyViewHolder<Events> {
TextView date, title, summary;
public EVHolder(View v) {
super(v);
date = v.findViewById(R.id.date);
title = v.findViewById(R.id.title);
summary = v.findViewById(R.id.summary);
}
@Override
public void bindView(Events c) {
date.setText(c.date);
title.setText(c.title);
summary.setText(c.summary);
}
}
Create Items list variable and adapters with very few lines by passing items, class and layout in the adapter
List<Events> items = new ArrayList<>();
MyRecyclerView recycler = findViewById(R.id.recycler);
RecyclerViewAdapter adapter = new RecyclerViewAdapter(this, items, EVHolder.class, R.layout.row_event);
recycler.setAdapter(adapter);
ClickListener can be added with following lines
recycler.setOnItemClickListener(new MyRecyclerView.OnItemClickListener() {
@Override
public void onItemClick(int position) {
Toast.makeText(MainActivity.this, "Recycler Item Clicked " + position, Toast.LENGTH_SHORT).show();
}
});
Its all done.
More example and implementation can be found here . Hope this helps !!!
I already found it:
SELECT grantee, privilege_type
FROM information_schema.role_table_grants
WHERE table_name='mytable'
In my case I had looked at some tables in the DB prior to executing this action. My user account was holding an active connection to this DB in SSMS. Once I disconnected from the server in SSMS (leaving the 'Take database offline' dialog box open) the operation succeeded.
Say you have activity stack like A>B>C>D>E. You are at activity D, and you want to close your app. This is what you wil do -
In Activity from where you want to close (Activity D)-
Intent intent = new Intent(D.this,A.class);
intent.putExtra("exit", "exit");
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP| Intent.FLAG_ACTIVITY_SINGLE_TOP);
startActivity(intent);
In your RootActivity (ie your base activity, here Activity A) -
@Override
protected void onNewIntent(Intent intent) {
super.onNewIntent(intent);
if (intent.hasExtra("exit")) {
setIntent(intent);
}
}
@Override
protected void onResume() {
super.onResume();
if (getIntent() != null) {
if (("exit").equalsIgnoreCase(getIntent().getStringExtra(("exit")))) {
onBackPressed();
}
}
}
onNewIntent is used because if activity is alive, it will get the first intent that started it. Not the new one. For more detail - Documentation
1) Server.MapPath(".")
-- Returns the "Current Physical Directory" of the file (e.g. aspx
) being executed.
Ex. Suppose D:\WebApplications\Collage\Departments
2) Server.MapPath("..")
-- Returns the "Parent Directory"
Ex. D:\WebApplications\Collage
3) Server.MapPath("~")
-- Returns the "Physical Path to the Root of the Application"
Ex. D:\WebApplications\Collage
4) Server.MapPath("/")
-- Returns the physical path to the root of the Domain Name
Ex. C:\Inetpub\wwwroot
This worked for me.
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button btnSendSMS = (Button) findViewById(R.id.btnSendSMS);
btnSendSMS.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
sendSMS("5556", "Hi You got a message!");
/*here i can send message to emulator 5556. In Real device
*you can change number*/
}
});
}
//Sends an SMS message to another device
private void sendSMS(String phoneNumber, String message) {
SmsManager sms = SmsManager.getDefault();
sms.sendTextMessage(phoneNumber, null, message, null, null);
}
You can add this line in AndroidManifest.xml
<uses-permission android:name="android.permission.SEND_SMS"/>

</div>
CSS:
.google-maps {
position: relative;
padding-bottom: 75%; // This is the aspect ratio
height: 0;
overflow: hidden;
}
.google-maps iframe {
position: absolute;
top: 0;
left: 0;
width: 100% !important;
height: 100% !important;
}
If you have a custom map size, remove the "height: 100% !important"
You are looking for the command scandir.
$path = '/tmp';
$files = scandir($path);
Following code will remove .
and ..
from the returned array from scandir
:
$files = array_diff(scandir($path), array('.', '..'));
Just add a Label without text and with background color. Set the Coordinates of your choice and also height and width. You can do it manually or with Interface Builder.
DNS info is cached at many places. If you have a server in Europe you may want to try to proxy through it
I had a similar issue, my error was:
Caused by: org.jboss.as.server.deployment.DeploymentUnitProcessingException: java.lang.ClassNotFoundException:org.glassfish.jersey.servlet.ServletContainer from [Module "deployment.RESTful_Services_CRUD.war:main" from Service Module Loader]
I use jboss
and glassfish
so I changed the web.xml
to the following:
<servlet-class>org.apache.catalina.servlets.DefaultServlet</servlet-class>
Instead of:
<servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
Hope this work for you.
Here is simple example of how you can do this.
Just replace the image file and you are done.
HTML Code
<input type="radio" id="r1" name="rr" />
<label for="r1"><span></span>Radio Button 1</label>
<p>
<input type="radio" id="r2" name="rr" />
<label for="r2"><span></span>Radio Button 2</label>
CSS
input[type="radio"] {
display:none;
}
input[type="radio"] + label {
color:#f2f2f2;
font-family:Arial, sans-serif;
font-size:14px;
}
input[type="radio"] + label span {
display:inline-block;
width:19px;
height:19px;
margin:-1px 4px 0 0;
vertical-align:middle;
background:url(check_radio_sheet.png) -38px top no-repeat;
cursor:pointer;
}
input[type="radio"]:checked + label span {
background:url(check_radio_sheet.png) -57px top no-repeat;
}
For a more modern solution, and if there is no need to support legacy browsers, you can do this:
.frame {_x000D_

Let's define a variable containing leading, trailing, and intermediate whitespace:
FOO=' test test test '
echo -e "FOO='${FOO}'"
# > FOO=' test test test '
echo -e "length(FOO)==${#FOO}"
# > length(FOO)==16
How to remove all whitespace (denoted by [:space:]
in tr
):

FOO_NO_WHITESPACE="$(echo -e "${FOO}" | tr -d '[:space:]')"
echo -e "FOO_NO_WHITESPACE='${FOO_NO_WHITESPACE}'"
# > FOO_NO_WHITESPACE='testtesttest'
echo -e "length(FOO_NO_WHITESPACE)==${#FOO_NO_WHITESPACE}"
# > length(FOO_NO_WHITESPACE)==12
How to remove leading whitespace only:
FOO=' test test test '

echo -e "FOO_NO_EXTERNAL_SPACE='${FOO_NO_EXTERNAL_SPACE}'"
# > FOO_NO_EXTERNAL_SPACE='test test test'
echo -e "length(FOO_NO_EXTERNAL_SPACE)==${#FOO_NO_EXTERNAL_SPACE}"
# > length(FOO_NO_EXTERNAL_SPACE)==14
Alternatively, if your bash supports it, you can replace echo -e "${FOO}" | sed ...
with sed ... <<<${FOO}
, like so (for trailing whitespace):
FOO_NO_TRAIL_SPACE="$(sed -e 's/[[:space:]]*$//' <<<${FOO})"
You have to change the size of object in drawable. It's too big for android to display. e.g. If you are setting image try image with less pixels. It works for me. Thanks. :)

It seems there's some misunderstanding. So, instead of trying to patch VS2013 here's and answer from a Microsoft guy: https://social.msdn.microsoft.com/Forums/vstudio/en-US/49ba9a67-d26a-4b21-80ef-caeb081b878e/will-c-60-ever-be-supported-by-vs-2013?forum=roslyn
So, please, read it and install VS2015.
question is not clear, but what i understand you need to select a catagory that has name attribute and should have child author with value specified , correct me if i am worng
here is a xpath
//category[@name='Required value'][./author[contains(.,'Required value')]]
e.g
//category[@name='Sport'][./author[contains(.,'James Small')]]
I believe that if you already have a package it installed, pip will not overwrite it with another version. Use -I
to ignore previous versions.
Suppose RetailerProfileModel is your Main class and RetailerPaymentModel is an inner class within it. You can create an object of the Inner class outside the class as follows:
RetailerProfileModel.RetailerPaymentModel paymentModel
= new RetailerProfileModel().new RetailerPaymentModel();
I guess I am coming late, but this info might be useful to anyone I found out something, which might be simple but important. if you use export on a function directly i.e
export const addPost = (id) =>{
...
}
Note while importing you need to wrap it in curly braces
i.e. import {addPost} from '../URL';
But when using export default i.e
const addPost = (id) =>{
...
}
export default addPost
,
Then you can import without curly braces i.e.
import addPost from '../url';
export default addPost
I hope this helps anyone who got confused as me.
Or could be:
$('input[type=file]').change(function () {
alert("hola");
});
To be specific: $('input[type=file]#fileUpload1').change(...
You need to make sure the IIS Management Console is installed.

I just encountered the very same problem today, and I came across this code:
private static string ByteArrayToHex(byte[] barray)
{
char[] c = new char[barray.Length * 2];
byte b;
for (int i = 0; i < barray.Length; ++i)
{
b = ((byte)(barray[i] >> 4));
c[i * 2] = (char)(b > 9 ? b + 0x37 : b + 0x30);
b = ((byte)(barray[i] & 0xF));
c[i * 2 + 1] = (char)(b > 9 ? b + 0x37 : b + 0x30);
}
return new string(c);
}
Source: Forum post byte[] Array to Hex String (see the post by PZahra). I modified the code a little to remove the 0x prefix.
I did some performance testing to the code and it was almost eight times faster than using BitConverter.ToString() (the fastest according to patridge's post).
docker rm container_name

Constructors don't return a type , just remove the return type which is void in your case. It would run fine then.
The *_test.go
file is a Go source like the others, you can initialize a new logger every time if you need to dump complex data structure, here an example:
// initZapLog is delegated to initialize a new 'log manager'
func initZapLog() *zap.Logger {
config := zap.NewDevelopmentConfig()
config.EncoderConfig.EncodeLevel = zapcore.CapitalColorLevelEncoder
config.EncoderConfig.TimeKey = "timestamp"
config.EncoderConfig.EncodeTime = zapcore.ISO8601TimeEncoder
logger, _ := config.Build()
return logger
}
Then, every time, in every test:
func TestCreateDB(t *testing.T) {
loggerMgr := initZapLog()
// Make logger avaible everywhere
zap.ReplaceGlobals(loggerMgr)
defer loggerMgr.Sync() // flushes buffer, if any
logger := loggerMgr.Sugar()
logger.Debug("START")
conf := initConf()
/* Your test here
if false {
t.Fail()
}*/
}
You might be able to use Object.assign(...)
to apply your properties to the created element. See comments for additional details.
Keep in mind that height
and width
attributes are defined in pixels, not percents. You'll have to use CSS to make it fluid.
var elem = document.createElement('img')_x000D_
Object.assign(elem, {_x000D_
className: 'my-image-class',_x000D_
src: 'https://dummyimage.com/320x240/ccc/fff.jpg',_x000D_
height: 120, // pixels_x000D_
width: 160, // pixels_x000D_
onclick: function () {_x000D_
alert('Clicked!')_x000D_
}_x000D_
})_x000D_
document.body.appendChild(elem)_x000D_
_x000D_
// One-liner:_x000D_
// document.body.appendChild(Object.assign(document.createElement(...), {...}))
_x000D_
.my-image-class {_x000D_
height: 100%;_x000D_
width: 100%;_x000D_
border: solid 5px transparent;_x000D_
box-sizing: border-box_x000D_

_x000D_

I had a same problem and i could fixed it! you should add C:\Program Files (x86)\Microsoft SDKs\Windows\v7.1A\Lib\x64 for 64 bit system / C:\Program Files (x86)\Microsoft SDKs\Windows\v7.1A\Lib for 32 bit system in property manager-> Linker-> General->Additional library Directories
maybe it can solve the problem of somebody in the future!
You can put in in a paragraph
<p style="text-align:center;"><a href="contact.html" class="button large hpbottom">Get Started</a></p>
To align a div in the center, you have to do 2 things: - Make the div a fixed width - Set the left and right margin properties variable
<div class="container">
<div style="width:100px; margin:0 auto;">
<span>a centered div</span>
</div>
</div>
MAC OS It happened to me as well. I simply chose from the R toolbar MISC and then chose Change Working Directory. I was able to choose the directory that the .csv file was saved in. When I went back to the command line and typed getwd() the full directory was updated and correct and the read.csv function finally worked.
If you need to use trim in select query, you can also use regular expressions
SELECT * FROM table_name WHERE field RLIKE ' * query-string *'
return rows with field like ' query-string '
NSDate.init
with timeIntervalSinceNow
:
Ex:
let dateAfterMin = NSDate.init(timeIntervalSinceNow: (minutes * 60.0))
//Delete all records of table
db.execSQL("DELETE FROM " + TABLE_NAME);
//Reset the auto_increment primary key if you needed
db.execSQL("UPDATE SQLITE_SEQUENCE SET SEQ=0 WHERE NAME=" + TABLE_NAME);
//For go back free space by shrinking sqlite file
db.execSQL("VACUUM");
for element in somelist:
do_action(element)
somelist[:] = (x for x in somelist if not check(x))
If you really need to do it in one pass without copying the list
i=0
while i < len(somelist):
element = somelist[i]
do_action(element)
if check(element):
del somelist[i]
else:
i+=1
You can use the .delay()
function.
This is what you're after:
.addClass("load").delay(2000).addClass("done");
I've used JOpt and found it quite handy: http://jopt-simple.sourceforge.net/
The front page also provides a list of about 8 alternative libraries, check them out and pick the one that most suits your needs.
if you load up the XMLDoc I'm pretty sure the .ToString() function posses an overload for this.
But is this for debugging? The reason that it is sent like that is to take up less space (i.e stripping unneccessary whitespace from the XML).
obj1 != null
is the right way.
String defines IsNullOrEmpty
as a nicer way to say
obj1 == null || obj == String.Empty
so it does more than just check for nullity.
There may be other classes that define a method to check for a sematically "blank or null" object, but that would depend on the semantics of the class, and is by no means universal.
It's also possible to create extension method to do this kind of thing if it helps the readability of your code. For example, a similar approach to collections:
public static bool IsNullOrEmpty (this ICollection collection)
{
return collection == null || collection.Count == 0;
}
This is another option to write a pandas dataframe directly into a matplotlib table:
import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
fig, ax = plt.subplots()
# hide axes
fig.patch.set_visible(False)
ax.axis('off')
ax.axis('tight')
df = pd.DataFrame(np.random.randn(10, 4), columns=list('ABCD'))
ax.table(cellText=df.values, colLabels=df.columns, loc='center')
fig.tight_layout()
plt.show()
Actually you can just push query like this: this.$router.push({query: {plan: 'private'}})
I like to use a dict to rename the df.
rename = {'old1': 'new1', 'old2': 'new2'}
for col in df.schema.names:
df = df.withColumnRenamed(col, rename[col])
You can use <<
to append to a string in-place.
s = "foo"
old_id = s.object_id
s << "bar"
s #=> "foobar"
s.object_id == old_id #=> true
npm init
to create the package.json file and then you use
ls node_modules/ | xargs npm install --save
to fill in the modules you have in the node_modules folder.
Edit: @paldepind pointed out that the second command is redundant because npm init
now automatically adds what you have in your node_modules/ folder. I don't know if this has always been the case, but now at least, it works without the second command.
You can't databind to a property and then explictly assign a value to the databound property.
If it is the most recent commit, you can simply do this:
git commit --amend
This brings up the editor with the last commit message and lets you edit the message. (You can use -m
if you want to wipe out the old message and use a new one.)
And then when you push, do this:
git push --force-with-lease <repository> <branch>
Or you can use "+":
git push <repository> +<branch>
Or you can use --force
:
git push --force <repository> <branch>
Be careful when using these commands.
If someone else pushed changes to the same branch, you probably want to avoid destroying those changes. The --force-with-lease
option is the safest, because it will abort if there are any upstream changes (
If you don't specify the branch explicitly, Git will use the default push settings. If your default push setting is "matching", then you may destroy changes on several branches at the same time.
Anyone who already pulled will now get an error message, and they will need to update (assuming they aren't making any changes themselves) by doing something like this:
git fetch origin
git reset --hard origin/master # Loses local commits
Be careful when using reset --hard
. If you have changes to the branch, those changes will be destroyed.
The destroyed data is really just the old commit message, but --force
doesn't know that, and will happily delete other data too. So think of --force
as "I want to destroy data, and I know for sure what data is being destroyed." But when the destroyed data is committed, you can often recover old commits from the reflog—the data is actually orphaned instead of destroyed (although orphaned commits are periodically deleted).
If you don't think you're destroying data, then stay away from --force
... bad things might happen.
This is why --force-with-lease
is somewhat safer.
For this your android application must have uploaded into the android market. when you upload it on the android market then use the following code to open the market with your android application.
Intent intent = new Intent(Intent.ACTION_VIEW,Uri.parse("market://details?id=<packagename>"));
startActivity(intent);
If you want it to download and install from your own server then use the following code
Intent intent = new Intent(Intent.ACTION_VIEW,Uri.parse("http://www.example.com/sample/test.apk"));
startActivity(intent);
In Addition to @Dev Blanked answer, if you want to use an existing bean that was created by Spring the code can be modified to:
@RunWith(MockitoJUnitRunner.class)
public class DemoTest {
@Inject
private ApplicationContext ctx;
@Spy
private SomeService service;
@InjectMocks
private Demo demo;
@Before
public void setUp(){
service = ctx.getBean(SomeService.class);
}
/* ... */
}
This way you don't need to change your code (add another constructor) just to make the tests work.
There is a list of Sqlite wrappers for .Net at http://www.sqlite.org/cvstrac/wiki?p=SqliteWrappers. From what I've heard http://sqlite.phxsoftware.com/ is quite good. This particular one lets you access Sqlite through ADO.Net just like any other database.
Combined pwd
and getpass
approach, based on other answers:
try:
import pwd
except ImportError:
import getpass
pwd = None
def current_user():
if pwd:
return pwd.getpwuid(os.geteuid()).pw_name
else:
return getpass.getuser()
The RSACryptoServiceProvider(CspParameters)
constructor creates a keypair which is stored in the keystore on the local machine. If you already have a keypair with the specified name, it uses the existing keypair.
It sounds as if you are not interested in having the key stored on the machine.
So use the RSACryptoServiceProvider(Int32)
constructor:
public static void AssignNewKey(){
RSA rsa = new RSACryptoServiceProvider(2048); // Generate a new 2048 bit RSA key
string publicPrivateKeyXML = rsa.ToXmlString(true);
string publicOnlyKeyXML = rsa.ToXmlString(false);
// do stuff with keys...
}
EDIT:
Alternatively try setting the PersistKeyInCsp to false:
public static void AssignNewKey(){
const int PROVIDER_RSA_FULL = 1;
const string CONTAINER_NAME = "KeyContainer";
CspParameters cspParams;
cspParams = new CspParameters(PROVIDER_RSA_FULL);
cspParams.KeyContainerName = CONTAINER_NAME;
cspParams.Flags = CspProviderFlags.UseMachineKeyStore;
cspParams.ProviderName = "Microsoft Strong Cryptographic Provider";
rsa = new RSACryptoServiceProvider(cspParams);
rsa.PersistKeyInCsp = false;
string publicPrivateKeyXML = rsa.ToXmlString(true);
string publicOnlyKeyXML = rsa.ToXmlString(false);
// do stuff with keys...
}
I am using Angular 5.2 and when I use import 'rxjs/Rx';
it throws me the following lint error:
TSLint: This import is blacklisted, import a submodule instead (import-blacklist)
SOLUTION: Solved it by importing only the operators that I needed. Example follows:
import 'rxjs/add/operator/map';
import 'rxjs/add/operator/catch';
So the fix would be to import specifically only the necessary operators.
You could write a program that prints out BOOST_VERSION
and compile and run it as part of your build system. Otherwise, I think you're out of luck.
The problem might be with service mysql-server and apache2 running while system start. You can do the following.
sudo /opt/lampp/lampp stop
To stop already running default services
sudo service apache2 stop
sudo service mysql stop
To remove the services completely, so that they won't create problem in next system-restart, If you are in ubuntu(debian)
sudo apt-get remove apache2
sudo apt-get remove mysql-server
If you are in redhat or other, You could use yum
or similar command to uninstall the services
Then start the lampp again
sudo /opt/lampp/lampp start
Also, don't install mysql-server in the system, because it might start in system start-up, occupy the port, and create problem for mysql of lampp.

Fiddle : Demo
I would recommend having a look at this answer of mine, and see if it is relevant to what you are doing. If I understand your real problem, it's that your just not using your async action correctly and updating the redux "store", which will automatically update your component with it's new props.
This section of your code:
componentDidMount() {
if (this.props.isManager) {
this.props.dispatch(actions.fetchAllSites())
} else {
const currentUserId = this.props.user.get('id')
this.props.dispatch(actions.fetchUsersSites(currentUserId))
}
}
Should not be triggering in a component, it should be handled after executing your first request.
Have a look at this example from redux-thunk:
function makeASandwichWithSecretSauce(forPerson) {
// Invert control!
// Return a function that accepts `dispatch` so we can dispatch later.
// Thunk middleware knows how to turn thunk async actions into actions.
return function (dispatch) {
return fetchSecretSauce().then(
sauce => dispatch(makeASandwich(forPerson, sauce)),
error => dispatch(apologize('The Sandwich Shop', forPerson, error))
);
};
}
You don't necessarily have to use redux-thunk, but it will help you reason about scenarios like this and write code to match.
\n
is a line break. /n
is not.
use of \n
with
Now if you are trying to echo string to the page:
echo "kings \n garden";
output will be:
kings garden
you won't get garden
in new line because PHP is a server-side language, and you are sending output as HTML, you need to create line breaks in HTML. HTML doesn't understand \n
. You need to use the nl2br()
function for that.
What it does is:
Returns string with
<br />
or<br>
inserted before all newlines (\r\n, \n\r, \n and \r).
echo nl2br ("kings \n garden");
kings
garden
Note Make sure you're echoing/printing
\n
in double quotes, else it will be rendered literally as \n. because php interpreter parse string in single quote with concept of as is
so "\n" not '\n'
Now if you echo to text file you can use just \n
and it will echo to a new line, like:
$myfile = fopen("test.txt", "w+") ;
$txt = "kings \n garden";
fwrite($myfile, $txt);
fclose($myfile);
output will be:
kings
garden
The solution for me was to include
<configuration>
<config>
<add key="http_proxy" value="http://<IP>:<Port>" />
<add key="http_proxy.user" value="<user>" />
<add key="http_proxy.password" value="<password>" />
</config>
</configuration>
In the nuget.config
file.
On ubuntu 19.04, the default password are stored in the home directory:
cat ~/.jenkins/secrets/initialAdminPassword
A pop-up is a child of the parent window, but it is not a child of the parent DOCUMENT. It is its own independent browser window and is not contained by the parent.
Use an absolutely-positioned DIV and a translucent overlay instead.
EDIT - example
You need jQuery for this:
<style>
html, body {
height:100%
}
#overlay {
position:absolute;
z-index:10;
width:100%;
height:100%;
top:0;

background-color:#f00;
filter:alpha(opacity=10);
-moz-opacity:0.1;
opacity:0.1;
cursor:pointer;
}
.dialog {
position:absolute;
border:2px solid #3366CC;
width:250px;
height:120px;
background-color:#ffffff;
z-index:12;
}
</style>
<script type="text/javascript">
$(document).ready(function() { init() })
function init() {
$('#overlay').click(function() { closeDialog(); })
}
function openDialog(element) {
//this is the general dialog handler.
//pass the element name and this will copy
//the contents of the element to the dialog box
$('#overlay').css('height', $(document.body).height() + 'px')
$('#overlay').show()
$('#dialog').html($(element).html())
centerMe('#dialog')
$('#dialog').show();

function closeDialog() {
$('#overlay').hide();
$('#dialog').hide().html('');

function centerMe(element) {
//pass element name to be centered on screen
var pWidth = $(window).width();
var pTop = $(window).scrollTop()
var eWidth = $(element).width()
var height = $(element).height()
$(element).css('top', '130px')
//$(element).css('top',pTop+100+'px')
$(element).css('left', parseInt((pWidth / 2) - (eWidth / 2)) + 'px')
}
</script>
<a href="javascript:;//close me" onclick="openDialog($('#content'))">show dialog A</a>
<a href="javascript:;//close me" onclick="openDialog($('#contentB'))">show dialog B</a>

you can use also..
$('#apply-form input').blur(function()
{
if( $(this).val() == '' ) {
$(this).parents('p').addClass('warning');
}
});
if you have doubt about spaces,then try..
$('#apply-form input').blur(function()
{
if( $(this).val().trim() == '' ) {
$(this).parents('p').addClass('warning');
}
});
Use @Input
to pass your data to child components and then use ngOnChanges
(https://angular.io/api/core/OnChanges) to see if that @Input
changed on the fly.
You may use Fernet as follows:
from cryptography.fernet import Fernet
key = Fernet.generate_key()
f = Fernet(key)
encrypt_value = f.encrypt(b"YourString")
f.decrypt(encrypt_value)
It depends on what database you are using. In MySQL, you would use the "ALTER TABLE" syntax. I don't remember exactly how, but it would go something like this if you wanted to add a column called 'newcol' that was a 200 character varchar:
ALTER TABLE example ADD newCol VARCHAR(200) AFTER otherCol;
ScheduledExecutorService
The Answer by Lee is close, but only runs once. The Question seems to be asking to run indefinitely until an external state changes (until the response from a web site/service changes).
The ScheduledExecutorService
interface is part of the java.util.concurrent
package built into Java 5 and later as a more modern replacement for the old Timer
class.
Here is a complete example. Call either scheduleAtFixedRate
or scheduleWithFixedDelay
.
ScheduledExecutorService executor = Executors.newScheduledThreadPool ( 1 );
Runnable r = new Runnable () {
@Override
public void run () {
try { // Always wrap your Runnable with a try-catch as any uncaught Exception causes the ScheduledExecutorService to silently terminate.
System.out.println ( "Now: " + Instant.now () ); // Our task at hand in this example: Capturing the current moment in UTC.
if ( Boolean.FALSE ) { // Add your Boolean test here to see if the external task is fonud to be completed, as described in this Question.
executor.shutdown (); // 'shutdown' politely asks ScheduledExecutorService to terminate after previously submitted tasks are executed.
}
} catch ( Exception e ) {
System.out.println ( "Oops, uncaught Exception surfaced at Runnable in ScheduledExecutorService." );
}
}
};
try {
executor.scheduleAtFixedRate ( r , 0L , 5L , TimeUnit.SECONDS ); // ( runnable , initialDelay , period , TimeUnit )
Thread.sleep ( TimeUnit.MINUTES.toMillis ( 1L ) ); // Let things run a minute to witness the background thread working.
} catch ( InterruptedException ex ) {
Logger.getLogger ( App.class.getName () ).log ( Level.SEVERE , null , ex );
} finally {
System.out.println ( "ScheduledExecutorService expiring. Politely asking ScheduledExecutorService to terminate after previously submitted tasks are executed." );
executor.shutdown ();
}
Expect output like this:

In your php.ini
configuration file simply uncomment the extension:
;extension=pdo_mysql
(You can find your php.ini file in the php folder where your server is installed.)
make this to
extension=pdo_mysql
now you need to configure your .env file in find DB_DATABASE=
write in that database name which you used than migrate like if i used my database and database name is "abc" than i need to write there DB_DATABASE=abc
and save that .env file and run command again
php artisan migrate
so after run than you got some msg like as:
php artisan migrate
Migration table created successfully.
Make sure that your code is returning a value of given return-type irrespective of conditional statements
This code snippet was showing the same error
int search(char arr[], int start, int end, char value)
{
int i;
for(i=start; i<=end; i++)
{
if(arr[i] == value)
return i;
}
}
This is the working code after little changes
int search(char arr[], int start, int end, char value)
{
int i;
int index=-1;
for(i=start; i<=end; i++)
{
if(arr[i] == value)
index=i;
}
return index;
}
One way is to add it by yourself! How? By merging kwargs
with a bunch of defaults. This won't be appropriate on all occasions, for example, if the keys are not known to you in advance. However, if they are, here is a simple example:
import sys
def myfunc(**kwargs):
args = {'country':'England','town':'London',
'currency':'Pound', 'language':'English'}
diff = set(kwargs.keys()) - set(args.keys())
if diff:
print("Invalid args:",tuple(diff),file=sys.stderr)
return
args.update(kwargs)
print(args)
The defaults are set in the dictionary args
, which includes all the keys we are expecting. We first check to see if there are any unexpected keys in kwargs. Then we update args
with kwargs
which will overwrite any new values that the user has set. We don't need to test if a key exists, we now use args
as our argument dictionary and have no further need of kwargs
.
I was able to fix this issue by changing $(document).ready()
to window.onLoad()
.
You could always do just:
a=[1,2,3]
b=['a','b']
c=[1,2,3,4]
d=[1,2,3]
a==b #returns False
a==c #returns False
a==d #returns True
One should look at __init__
as a simple constructor in traditional OO languages. For example, if you are familiar with Java or C++, the constructor is passed a pointer to its own instance implicitly. In the case of Java, it is the this
variable. If one were to inspect the byte code generated for Java, one would notice two calls. The first call is to an "new" method, and then next call is to the init method (which is the actual call to the user defined constructor). This two step process enables creation of the actual instance before calling the constructor method of the class which is just another method of that instance.
Now, in the case of Python, __new__
is a added facility that is accessible to the user. Java does not provide that flexibility, due to its typed nature. If a language provided that facility, then the implementor of __new__
could do many things in that method before returning the instance, including creating a totally new instance of a unrelated object in some cases. And, this approach also works out well for especially for immutable types in the case of Python.
Use find
with a wildcard:
find . -name 'mystring*'
Starting from Swift 3.0 you can
var str = String(describing: Audience.friends)
For both elements use
display: inline-block;
the for the 'nav' element use
float: right;
You can use this implementation of Binary GCD algorithm
public class BinaryGCD {
public static int gcd(int p, int q) {
if (q == 0) return p;
if (p == 0) return q;
// p and q even
if ((p & 1) == 0 && (q & 1) == 0) return gcd(p >> 1, q >> 1) << 1;
// p is even, q is odd
else if ((p & 1) == 0) return gcd(p >> 1, q);
// p is odd, q is even
else if ((q & 1) == 0) return gcd(p, q >> 1);
// p and q odd, p >= q
else if (p >= q) return gcd((p-q) >> 1, q);
// p and q odd, p < q
else return gcd(p, (q-p) >> 1);
}
public static void main(String[] args) {
int p = Integer.parseInt(args[0]);
int q = Integer.parseInt(args[1]);
System.out.println("gcd(" + p + ", " + q + ") = " + gcd(p, q));
}
}

1st option
if you want to set your custom storyboard instead of a default view controller.
Change this attribute from info.plist file
<key>UISceneStoryboardFile</key>
<string>Onboarding</string>
Onboarding would be your storyboard name
to open this right-click on info.plist file and open as a source code
2nd option
1- Click on your project
2- Select your project from the target section
3- Move to Deployment interface section
4- Change your storyboard section from Main Interface field
Please remember set your storyboard initial view controller
The relative reference would be
<img src="../images/logo.png">
If you know the location relative to the root of the server, that may be simplest approach for an app with a complex nested directory hierarchy - it would be the same from all folders.
For example, if your directory tree depicted in your question is relative to the root of the server, then index.html and sub_folder/sub.html would both use:
<img src="/images/logo.png">
If the images folder is instead in the root of an application like foo
below the server root (e.g. http://www.example.com/foo
), then index.html (http://www.example.com/foo/index.html
) e.g and sub_folder/sub.html (http://www.example.com/foo/sub_folder/sub.html
) both use:
<img src="/foo/images/logo.png">
You can create a PrintStream wrapping around your OutputStream and then just call it's print(String):
final OutputStream os = new FileOutputStream("/tmp/out");
final PrintStream printStream = new PrintStream(os);
printStream.print("String");
printStream.close();

JS (writing to the txt file):
function writeToFile(d1, d2){
var fso = new ActiveXObject("Scripting.FileSystemObject");
var fh = fso.OpenTextFile("data.txt", 8, false, 0);
fh.WriteLine(d1 + ',' + d2);
fh.Close();
}
var submit = document.getElementById("submit");
submit.onclick = function () {
var id = document.getElementById("id").value;
var content = document.getElementById("content").value;
writeToFile(id, content);
}
checking a particular row:
function readFile(){
var fso = new ActiveXObject("Scripting.FileSystemObject");
var fh = fso.OpenTextFile("data.txt", 1, false, 0);
var lines = "";
while (!fh.AtEndOfStream) {
lines += fh.ReadLine() + "\r";
}
fh.Close();
return lines;
}
var search = document.getElementById("search");
search.onclick = function () {
var input = document.getElementById("input").value;
if (input != "") {
var text = readFile();
var lines = text.split("\r");
lines.pop();
var result;
for (var i = 0; i < lines.length; i++) {
if (lines[i].match(new RegExp(input))) {
result = "Found: " + lines[i].split(",")[1];
}
}
if (result) { alert(result); }
else { alert(input + " not found!"); }
}
}
Put these inside a .hta
file and run it. Tested on W7, IE11. It's working. Also if you want me to explain what's going on, say so.
First, I thought:
"...In Microsoft SQL Server the
SELECT...INTO
automatically creates the new table whereas Oracle seems to require you to manually create it before executing theSELECT...INTO
statement..."
But after manually generating a table, it still did not work, still showing the "missing keyword" error.
So I gave up this time and solved it by first manually creating the table, then using the "classic" SELECT
statement:
INSERT INTO assignment_20081120 SELECT * FROM assignment;
Which worked as expected. If anyone come up with an explanaition on how to use the SELECT...INTO
in a correct way, I would be happy!
You have to add the reference to System.configuration
in your solution. Also, include using System.Configuration;
. Once you do that, you'll have access to all the configuration settings.
I had an issue with Swedish/Norwegian letters showing up as question marks, despite having specified:
contentType: "application/json; charset=utf-8",
This was solved by adding encodeURIComponent
to the string.
url: "/set_comment.do?text=" + encodeURIComponent(comment),

Edit: One update if you need Gzip compression on WebAPI responses. I wasn't aware our WebAPI wasn't returning Gzipped responses until recently and scratched my head for a while because we had dynamic and static compression turned on in web.config. We looked at writing our own compression services and response handlers (still on WebAPI 2 not on .NET Core where it's easier now), but that was too cumbersome for what seemed like something we should just be able to turn on.
(If you're interested here's what we were looking at for our own compression service https://krzysztofjakielaszek.com/2017/03/26/webapi2-response-compression-gzip-brotli-deflate/
EDIT: Link is now offline, but you can view the code/content here: https://web.archive.org/web/20190608161201/https://krzysztofjakielaszek.com/2017/03/26/webapi2-response-compression-gzip-brotli-deflate/ )
Instead, we found this great post by Ben Foster (http://benfoster.io/blog/aspnet-web-api-compression) If you can modify applicationHost.config (running your own servers), you can pop that config file open and add the mimeTypes you want to compress (I pulled the relevant ones based on what our API was returning to clients from our Web.Config). Save that file, IIS will pickup your changes, recycle app pools, and your WebAPI will start returning gzip compressed responses to clients who request it.
If you don't see gzipped responses, check the response content type with Fiddler or Chrome/Firefox Dev Tools, and ensure it matches what you added. I had to change the view mode (use large request rows) in Chrome Dev Tools to ensure it showed the total size vs transferred size. If everything validates, try rebooting the server once to just ensure it was properly applied. I did have one syntax error where when I opened up the site in IIS, IIS poppped open a message about a parsing error that I had to fix in the config file.

The left column is the specific CPU index and the right most column is the usage of the CPU. If you don't specify the --no-aggr
option, the result will aggregated together. The --pid=pid
option will help if you want to monitor a running process.
Try -a --per-core
or -a perf-socket
too, which will present more classified information.
More about usage of perf stat
can be seen in this tutorial: perf cpu statistic, also perf help stat
will help on the meaning of the options.
You need to uninstall it because you are using a different signature than the original. If it is not working it might be because it is still installed for another user on the device. To completely uninstall, go to Settings -> Apps -> HAgnostic News -> Options (the three dots on top right) -> Uninstall for all users
If you are using Linux and you got the permission error, you will need to raise the allowed limit in the /etc/limits.conf
or /etc/security/limits.conf
file (where the file is located depends on your specific Linux distribution).
For example to allow anyone on the machine to raise their number of open files up to 10000 add the line to the limits.conf
file.
* hard nofile 10000
Then logout and relogin to your system and you should be able to do:
ulimit -n 10000
without a permission error.
Why not use ES6?

More generalized approach may be to merge PARSENAME and % operator. (as answered in two of the answers above)
Results as per 1st approach above by SQLMenace
select PARSENAME(0.001,1)
Result: 001
select PARSENAME(0.0010,1)
Result: 0010
select PARSENAME(-0.001,1)
Result: 001
select PARSENAME(-1,1)
Result: -1 --> Should not return integer part
select PARSENAME(0,1)
Result: 0
select PARSENAME(1,1)
Result: 1 --> Should not return integer part
select PARSENAME(100.00,1)
Result: 00
Results as per 1st approach above by Pavel Morshenyuk "0." is part of result in this case.
SELECT (100.0001 % 1)
Result: 0.0001
SELECT (100.0010 % 1)
Result: 0.0010
SELECT (0.0001 % 1)
Result: 0.0001
SELECT (0001 % 1)
Result: 0
SELECT (1 % 1)
Result: 0
SELECT (100 % 1)
Result: 0
Combining both:
SELECT PARSENAME((100.0001 % 1),1)
Result: 0001
SELECT PARSENAME((100.0010 % 1),1)
Result: 0010
SELECT PARSENAME((0.0001 % 1),1)
Result: 0001
SELECT PARSENAME((0001 % 1),1)
Result: 0
SELECT PARSENAME((1 % 1),1)
Result: 0
SELECT PARSENAME((100 % 1),1)
Result: 0
But still one issue which remains is the zero after the non zero numbers are part of the result (Example: 0.0010 -> 0010). May be one have to apply some other logic to remove that.
I had the same problem, there was no extension=php_soap.dll in my php.ini But this was because I had copied the php.ini from a old and previous php version (not a good idea). I found the dll in the ext directory so I just could put it myself into the php.ini extension=php_soap.dll After Apache restart all worked with soap :)
EDIT: Bootstrap 3.3.4 has solved this problem (and other modal issues) so if you can update your bootstrap CSS and JS that would be the best solution. If you can't update the solution below will still work and essentially does the same thing as bootstrap 3.3.4 (recalculate and apply padding).
As Bass Jobsen pointed out, newer versions of Bootstrap have the z-index solved. The modal-open class and padding-right were still problems for me but this scripts inspired by Yermo Lamers solution solves it. Just drop it in your JS file and enjoy.
$(document).on('hide.bs.modal', '.modal', function (event) {
var padding_right = 0;
$.each($('.modal'), function(){
if($(this).hasClass('in') && $(this).modal().data('bs.modal').scrollbarWidth > padding_right) {
padding_right = $(this).modal().data('bs.modal').scrollbarWidth
}
});
$('body').data('padding_right', padding_right + 'px');
});
$(document).on('hidden.bs.modal', '.modal', function (event) {
$('body').data('open_modals', $('body').data('open_modals') - 1);
if($('body').data('open_modals') > 0) {
$('body').addClass('modal-open');
$('body').css('padding-right', $('body').data('padding_right'));
}
});
$(document).on('shown.bs.modal', '.modal', function (event) {
if (typeof($('body').data('open_modals')) == 'undefined') {
$('body').data('open_modals', 0);
}
$('body').data('open_modals', $('body').data('open_modals') + 1);
$('body').css('padding-right', (parseInt($('body').css('padding-right')) / $('body').data('open_modals') + 'px'));
});
So by adding the URL at the the end of the href, Each link will open in the same window? You could also probably use _BLANK within the HTML to do the same thing.
Easy as pie:
Open Eclipse and go to Help-> Software Updates-> Find and Install Select "Search for new features to install" and click "Next" Create a New Remote Site with the following details:
Name: PDT
URL: http://download.eclipse.org/tools/pdt/updates/4.0.1
Get the latest above mentioned URLfrom -
http://www.eclipse.org/pdt/index.html#download
Check the PDT box and click "Next" to start the installation
Hope it helps
Tom's answer is excellent I agree fully with his answers!
An interesting aspect of this question is, whether you need the List
type itself and its inherent ordering.
If not you can degrade to Iterable
or Collection
which gives you some flexibility on passing around data structures that are sorted on insertion time, rather than at the time when you want to check.
If the order never matters (and you don't have duplicate elements) consider using a Set
.
If the order matters but is defined by insertion time (and you don't have duplicates) consider a LinkedHashSet
which is like a TreeSet but is ordered by insertion time (duplicates are not counted). This also gives you O(1)
amortized access insted of O(log n)
.
If it´s in the global scope it´s better to use:
function foo()
{
alert('foo');
}
var a = 'foo';
window[a]();
than eval()
. Because eval()
is evaaaaaal.
Exactly like Nosredna said 40 seconds before me that is >.<
I was looking through all the wordy explanations so instead turned to a video from University of New South Wales for rescue.Here is the simple explanation: if we have a cell that has address x
and value 7
, the indirect way to ask for address of value 7
is &7
and the indirect way to ask for value at address x
is *x
.So (cell: x , value: 7) == (cell: &7 , value: *x)
.Another way to look into it: John
sits at 7th seat
.The *7th seat
will point to John
and &John
will give address
/location of the 7th seat
. This simple explanation helped me and hope it will help others as well. Here is the link for the excellent video: click here.
Here is another example:
#include <stdio.h>
int main()
{
int x; /* A normal integer*/
int *p; /* A pointer to an integer ("*p" is an integer, so p
must be a pointer to an integer) */
p = &x; /* Read it, "assign the address of x to p" */
scanf( "%d", &x ); /* Put a value in x, we could also use p here */
printf( "%d\n", *p ); /* Note the use of the * to get the value */
getchar();
}
Add-on: Always initialize pointer before using them.If not, the pointer will point to anything, which might result in crashing the program because the operating system will prevent you from accessing the memory it knows you don't own.But simply putting p = &x;
, we are assigning the pointer a specific location.
Use console.log(JSON.stringify(result))
to get the JSON in a string format.
EDIT: If your intention is to get the id and other properties from the result object and you want to see it console to know if its there then you can check with hasOwnProperty
and access the property if it does exist:
var obj = {id : "007", name : "James Bond"};
console.log(obj); // Object { id: "007", name: "James Bond" }
console.log(JSON.stringify(obj)); //{"id":"007","name":"James Bond"}
if (obj.hasOwnProperty("id")){
console.log(obj.id); //007
}
Here is a simple function which does exactly this :
#include <windows.h>
#include <string>
bool dirExists(const std::string& dirName_in)
{
DWORD ftyp = GetFileAttributesA(dirName_in.c_str());
if (ftyp == INVALID_FILE_ATTRIBUTES)
return false; //something is wrong with your path!
if (ftyp & FILE_ATTRIBUTE_DIRECTORY)
return true; // this is a directory!
return false; // this is not a directory!
}
I have used the @RaviThapliyal & @Don Rolling's code but made a little modification. Since we are replacing the   with empty string but instead   should be replaced with space, so added an additional step. It worked for me like a charm.
public static string FormatString(string value) {
var step1 = Regex.Replace(value, @"<[^>]+>", "").Trim();
var step2 = Regex.Replace(step1, @" ", " ");
var step3 = Regex.Replace(step2, @"\s{2,}", " ");
return step3;
}
Used &nbps without semicolon because it was getting formatted by the Stack Overflow.
On the File menu, choose Advanced Save Options, you can control it there.
Edit: Here's the documentation, you should have a file open first.
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

If you would like to use autocomplete all the time without having to worry about hitting Ctrl + Spacebar or your own keyboard shortcut, you can make the following adjustment in the Eclipse preferences to trigger autocomplete simply by typing several different characters:
abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ._
Now any time that you type any of these characters, Eclipse will trigger autocomplete suggestions based on the context.
the solution here worked for me : https://community.hortonworks.com/articles/4427/fix-under-replicated-blocks-in-hdfs-manually.html

var newDate = new Date();
newDate.setTime(unixtime*1000);

Where unixtime
is the time returned by your sql db. Here is a fiddle if it helps.
For example, using it for the current time:
document.write( new Date().toUTCString() );

I think ./gradlew tasks
is same with Android studio sync
. Why? I will explain it.
I meet a problem when I test jacoco coverage report. When I run ./gradlew clean :Test:testDebugUnitTest
in command line directly , error appear.
Error opening zip file or JAR manifest missing : build/tmp/expandedArchives/org.jacoco.agent-0.8.2.jar_5bdiis3s7lm1rcnv0gawjjfxc/jacocoagent.jar
However, if I click android studio sync firstly , it runs OK. Because the build/../jacocoagent.jar
appear naturally.
I dont know why, maybe there is bug in jacoco plugin. Unit I find running .gradlew tasks
makes the jar appear as well. So I can get the same result in gralde script.
Besides, gradle --recompile-scripts
does not work for the problem.
I've been wrestling with the same issue today for a checkbox that binds to a nullable bool, and since I can't change my model (not my code) I had to come up with a better way of handling this. It's a bit brute force, but it should work for 99% of cases I might encounter. You'd obviously have to do some manual population of valid attributes for each input type, but I think I've gotten all of them for checkbox.
In my Boolean.cshtml editor template:
@model bool?
@{
var attribs = new Dictionary<string, object>();
var validAttribs = new string[] {"style", "class", "checked", "@class",
"classname","id", "required", "value", "disabled", "readonly",
"accesskey", "lang", "tabindex", "title", "onblur", "onfocus",
"onclick", "onchange", "ondblclick", "onmousedown", "onmousemove",
"onmouseout", "onmouseover", "onmouseup", "onselect"};
foreach (var item in ViewData)
{
if (item.Key.ToLower().IndexOf("data_") == 0 || item.Key.ToLower().IndexOf("aria_") == 0)
{
attribs.Add(item.Key.Replace('_', '-'), item.Value);
}
else
{
if (validAttribs.Contains(item.Key.ToLower()))
{
attribs.Add(item.Key, item.Value);
}
}
}
}
@Html.CheckBox("", Model.GetValueOrDefault(), attribs)
Using environment variable is sometimes more convenient when you do not control the build scripts / process.
For C includes use C_INCLUDE_PATH
.
For C++ includes use CPLUS_INCLUDE_PATH
.
See this link for other gcc environment variables.
# `pip install` will automatically run `gcc` using parameters
# specified in the `asyncpg` package (that I do not control)
C_INCLUDE_PATH=/home/scott/.pyenv/versions/3.7.9/include/python3.7m pip install asyncpg
set C_INCLUDE_PATH="C:\Users\Scott\.pyenv\versions\3.7.9\include\python3.7m"
pip install asyncpg
# clear the environment variable so it doesn't affect other builds
set C_INCLUDE_PATH=
i think u can set the heiht at runtime for 1 item just scrollView.setHeight(200px)
, for 2 items scrollView.setheight(400px)
for 3 or more scrollView.setHeight(600px)
In order to do this in SQL Server, you must order the query by a column, so you can specify the rows you want.
Example:
select * from table order by [some_column]
offset 10 rows
FETCH NEXT 10 rows only
I found it... for (property in object) { // do stuff }
will list all the properties, and therefore all the globally declared variables on the window object..
dataString suggests the data is formatted in a string (and maybe delimted by a character).
$data = explode(",", $_POST['data']);
foreach($data as $d){
echo $d;
}
if dataString is not a string but infact an array (what your question indicates) use JSON.
Have a table row with nested table:
<tr class='dummyRow' style='display: none;'>
<td>
<table style='display: none;'>All row content inside here</table>
</td>
</tr>
$('.dummyRow').show().find("table").slideDown();
Note: the row and it's content (here it is "table"
) both should be hidden before animation starts.
$('.dummyRow').find("table").slideUp('normal', function(){$('.dummyRow').hide();});
The second parameter (function()
) is a callback.
Simple!!
Note that there are also several options that can be added as parameters of the slide up/down functions (the most common being durations of 'slow'
and 'fast'
).
First, open Device Manager by searching for it in the Windows search bar.
Then, click ports and right click the port the Arduino is connected to. Then, go to Port settings → Advanced. Next, select any port that is not in use and is not the port the Arduino is currently connected to. Then click OK and unplug + replug your Arduino. This works most of the time with any Arduino board.
It works for me.... I have built a face book wall...
Here is the basis of my code:
// SETS MY TEXT AREA TO EMPTY (NO VALUE)
$('textarea#message_wall').val('');
I was creating several buttons for each phone number in an array so each button needed a different phone number to call. I used the setTag function as I was creating several buttons within a for loop:
for (NSInteger i = 0; i < _phoneNumbers.count; i++) {
UIButton *phoneButton = [[UIButton alloc] initWithFrame:someFrame];
[phoneButton setTitle:_phoneNumbers[i] forState:UIControlStateNormal];
[phoneButton setTag:i];
[phoneButton addTarget:self
action:@selector(call:)
forControlEvents:UIControlEventTouchUpInside];
}
Then in my call: method I used the same for loop and an if statement to pick the correct phone number:
- (void)call:(UIButton *)sender
{
for (NSInteger i = 0; i < _phoneNumbers.count; i++) {
if (sender.tag == i) {
NSString *callString = [NSString stringWithFormat:@"telprompt://%@", _phoneNumbers[i]];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:callString]];
}
}
}
Consider using default filter if it is what you need. For example:
{% set host = jabber.host | default(default.host) -%}
or use more fallback values with "hardcoded" one at the end like:
{% set connectTimeout = config.stackowerflow.connect.timeout | default(config.stackowerflow.timeout) | default(config.timeout) | default(42) -%}
You don't need to learn JPA. You can use my easy-criteria for JPA2 (https://sourceforge.net/projects/easy-criteria/files/). Here is the example
CriteriaComposer<Pet> petCriteria CriteriaComposer.from(Pet.class).
where(Pet_.type, EQUAL, "Cat").join(Pet_.owner).where(Ower_.name,EQUAL, "foo");
List<Pet> result = CriteriaProcessor.findAllEntiry(petCriteria);
OR
List<Tuple> result = CriteriaProcessor.findAllTuple(petCriteria);

The top 2 answers (from Adam Robinson and Andrejs Cainikovs) are kinda, sorta correct, in that they do technically work, but their explanations are wrong and so could be misleading in many cases. For example, while the SQL_Latin1_General_CP1_CI_AS
collation will work in many cases, it should not be assumed to be the appropriate case-insensitive collation. In fact, given that the O.P. is working in a database with a case-sensitive (or possibly binary) collation, we know that the O.P. isn't using the collation that is the default for so many installations (especially any installed on an OS using US English as the language): SQL_Latin1_General_CP1_CI_AS
. Sure, the O.P. could be using SQL_Latin1_General_CP1_CS_AS
, but when working with VARCHAR
data, it is important to not change the code page as it could lead to data loss, and that is controlled by the locale / culture of the collation (i.e. Latin1_General vs French vs Hebrew etc). Please see point # 9 below.
The other four answers are wrong to varying degrees.
I will clarify all of the misunderstandings here so that readers can hopefully make the most appropriate / efficient choices.
Do not use UPPER()
. That is completely unnecessary extra work. Use a COLLATE
clause. A string comparison needs to be done in either case, but using UPPER()
also has to check, character by character, to see if there is an upper-case mapping, and then change it. And you need to do this on both sides. Adding COLLATE
simply directs the processing to generate the sort keys using a different set of rules than it was going to by default. Using COLLATE
is definitely more efficient (or "performant", if you like that word :) than using UPPER()
, as proven in this test script (on PasteBin).
There is also the issue noted by @Ceisc on @Danny's answer:
In some languages case conversions do not round-trip. i.e. LOWER(x) != LOWER(UPPER(x)).
The Turkish upper-case "I" is the common example.
No, collation is not a database-wide setting, at least not in this context. There is a database-level default collation, and it is used as the default for altered and newly created columns that do not specify the COLLATE
clause (which is likely where this common misconception comes from), but it does not impact queries directly unless you are comparing string literals and variables to other string literals and variables, or you are referencing database-level meta-data.
No, collation is not per query.
Collations are per predicate (i.e. something operand something) or expression, not per query. And this is true for the entire query, not just the WHERE
clause. This covers JOINs, GROUP BY, ORDER BY, PARTITION BY, etc.
No, do not convert to VARBINARY
(e.g.convert(varbinary, myField) = convert(varbinary, 'sOmeVal')
) for the following reasons:
_BIN2
if you are using SQL Server 2008 or newer, else you have no choice but to use one that ends with _BIN
. If the data is NVARCHAR
then it doesn't matter which locale you use as they are all the same in that case, hence Latin1_General_100_BIN2
always works. If the data is VARCHAR
, you must use the same locale that the data is currently in (e.g. Latin1_General
, French
, Japanese_XJIS
, etc) because the locale determines the code page that is used, and changing code pages can alter the data (i.e. data loss).CONVERT()
it will use the 30 default value. The danger is, if the string can be over 30 bytes, it will get silently truncated and you will likely get incorrect results from this predicate.No, LIKE
is not always case-sensitive. It uses the collation of the column being referenced, or the collation of the database if a variable is compared to a string literal, or the collation specified via the optional COLLATE
clause.
LCASE
is not a SQL Server function. It appears to be either Oracle or MySQL. Or possibly Visual Basic?
Since the context of the question is comparing a column to a string literal, neither the collation of the instance (often referred to as "server") nor the collation of the database have any direct impact here. Collations are stored per each column, and each column can have a different collation, and those collations don't need to be the same as the database's default collation or the instance's collation. Sure, the instance collation is the default for what a newly created database will use as its default collation if the COLLATE
clause wasn't specified when creating the database. And likewise, the database's default collation is what an altered or newly created column will use if the COLLATE
clause wasn't specified.
You should use the case-insensitive collation that is otherwise the same as the collation of the column. Use the following query to find the column's collation (change the table's name and schema name):
SELECT col.*
FROM sys.columns col
WHERE col.[object_id] = OBJECT_ID(N'dbo.TableName')
AND col.[collation_name] IS NOT NULL;
Then just change the _CS
to be _CI
. So, Latin1_General_100_CS_AS
would become Latin1_General_100_CI_AS
.
If the column is using a binary collation (ending in _BIN
or _BIN2
), then find a similar collation using the following query:
SELECT *
FROM sys.fn_helpcollations() col
WHERE col.[name] LIKE N'{CurrentCollationMinus"_BIN"}[_]CI[_]%';
For example, assuming the column is using Japanese_XJIS_100_BIN2
, do this:
SELECT *
FROM sys.fn_helpcollations() col
WHERE col.[name] LIKE N'Japanese_XJIS_100[_]CI[_]%';

Bower maintains a single version of modules, it only tries to help you select the correct/best one for you.
NPM is better for node modules because there is a module system and you're working locally. Bower is good for the browser because currently there is only the global scope, and you want to be very selective about the version you work with.
Try this:
$mpdf->Output('my_filename.pdf','D');
because:
D
- means Download
F
- means File-save only
You must not use StreamReader
for binary files (like gifs or jpgs). StreamReader
is for text data. You will almost certainly lose data if you use it for arbitrary binary data. (If you use Encoding.GetEncoding(28591) you will probably be okay, but what's the point?)
Why do you need to use a StreamReader
at all? Why not just keep the binary data as binary data and write it back to disk (or SQL) as binary data?
EDIT: As this seems to be something people want to see... if you do just want to copy one stream to another (e.g. to a file) use something like this:
/// <summary>
/// Copies the contents of input to output. Doesn't close either stream.
/// </summary>
public static void CopyStream(Stream input, Stream output)
{
byte[] buffer = new byte[8 * 1024];
int len;
while ( (len = input.Read(buffer, 0, buffer.Length)) > 0)
{
output.Write(buffer, 0, len);
}
}
To use it to dump a stream to a file, for example:
using (Stream file = File.Create(filename))
{
CopyStream(input, file);
}
Note that Stream.CopyTo
was introduced in .NET 4, serving basically the same purpose.

Assuming you use the declarative style (i.e. ORM classes), it is pretty easy:
query = db_session.query(User.id, User.name).filter(User.id.in_([123,456]))
results = query.all()
db_session
is your database session here, while User
is the ORM class with __tablename__
equal to "users"
.

In Oracle PL/SQL, if you are running a query that may return multiple rows, you need a cursor to iterate over the results. The simplest way is with a for loop, e.g.:
declare
myname varchar2(20) := 'tom';
begin
for result_cursor in (select * from mytable where first_name = myname) loop
dbms_output.put_line(result_cursor.first_name);
dbms_output.put_line(result_cursor.other_field);
end loop;
end;
If you have a query that returns exactly one row, then you can use the select...into...
syntax, e.g.:
declare
myname varchar2(20);
begin
select first_name into myname
from mytable
where person_id = 123;
end;
