I had the same error and fixed it. It turned out to be a silly reason.
This was the culprit:
<script src="app.js"/>

If the response is in json you could do something like (python3):
import json
import requests as reqs
# Make the HTTP request.
response = reqs.get('http://demo.ckan.org/api/3/action/group_list')
# Use the json module to load CKAN's response into a dictionary.
response_dict = json.loads(response.text)
for i in response_dict:
print("key: ", i, "val: ", response_dict[i])
To see everything in the response you can use .__dict__
:
print(response.__dict__)
Try this:
from tkinter import *
import os
import sys
root = Tk()
root.iconbitmap(os.path.join(sys.path[0], '<your-ico-file>'))
root.mainloop()
Note: replace <your-ico-file>
with the name of the ico file you are using otherwise it won't work.
I have tried this in Python 3. It worked.
I had this happen in Visual Studio 2015 too for an interesting reason. Just adding it here in case it happens to someone else.
I already had number of files in project and I was adding another one that would have main function in it, however when I initially added the file I made a typo in the extension (.coo instead of .cpp). I corrected that but when I was done I got this error. It turned out that Visual Studio was being smart and when file was added it decided that it is not a source file due to the initial extension.
Right-clicking on file in solution explorer and selecting Properties -> General -> ItemType and setting it to "C/C++ compiler" fixed the issue.
Here are some ways:
1. if($("div").hasClass("mydivclass")){
//Your code
//It returns true if any div has 'mydivclass' name. It is a based on the class name
}
2. if($("#myid1").hasClass("mydivclass")){
//Your code
// It returns true if specific div(myid1) has this class "mydivclass" name.
// It is a based on the specific div id's.
}
3. if($("div[class='mydivclass']").length > 0){
//Your code
// It returns all the divs whose class name is "mydivclass"
// and it's length would be greater than one.
}
We can use any one of the abobe defined ways based on the requirement.
In your web.config (on the server) add
<system.diagnostics>
<sources>
<source name="System.ServiceModel" switchValue="Information, ActivityTracing" propagateActivity="true">
<listeners>
<add name="traceListener" type="System.Diagnostics.XmlWriterTraceListener" initializeData="C:\logs\Traces.svclog"/>
</listeners>
</source>
</sources>
</system.diagnostics>
Auto-incrementing the index in a loop:
myArr[(len(myArr)+1)]={"key":"val"}
your div looks like this:
<div id="someId">Some Value</div>
With jquery:
<script type="text/javascript">
$(function(){
var text = $('#someId').html();
//or
var text = $('#someId').text();
};
</script>
I have found that often if z-index isn't working its because its parent/siblings don't have a specified z-index.
So if you have:
<div id="1">
<a id="2" style="z-index:2"></a>
<div id="3" style="z-index:1"></div>
<button id="4"></button>
</div>
item #3, or even #4, may be contesting #2 for the click/hover space, though if you set #1 to z-index 0, the siblings who's z-index put them in independant stacks now are in the same stack and will z-index properly.
This has a helpful and fairly humanized description: http://foohack.com/2007/10/top-5-css-mistakes/
The 'at' command.
"The AT command schedules commands and programs to run on a computer at a specified time and date. The Schedule service must be running to use the AT command."
And when you want all tables for some reason ?
You can generate these commands in SSMS:
SELECT
CONCAT('sqlcmd -S ',
'Your(local?)SERVERhere'
,' -d',
'YourDB'
,' -E -s, -W -Q "SELECT * FROM ',
TABLE_NAME,
'" >',
TABLE_NAME,
'.csv') FROM INFORMATION_SCHEMA.TABLES
And get again rows like this
sqlcmd -S ... -d... -E -s, -W -Q "SELECT * FROM table1" >table1.csv
sqlcmd -S ... -d... -E -s, -W -Q "SELECT * FROM table2" >table2.csv
...
There is also option to use better TAB as delimiter, but it would need a strange Unicode character - using Alt+9 in CMD, it came like this ? (Unicode CB25), but works only by copy/paste to command line not in batch.
There is an example of inheritance using C in Jim Larson's 1996 talk given at the Section 312 Programming Lunchtime Seminar here: High and Low-Level C.
gcc 7.4.0 can not compile codes as below:
#include <stdio.h>
const char * const str1 = "str1";
const char * str2 = str1;
int main() {
printf("%s - %s\n", str1, str2);
return 0;
}
constchar.c:3:21: error: initializer element is not constant const char * str2 = str1;
In fact, a "const char *" string is not a compile-time constant, so it can't be an initializer. But a "const char * const" string is a compile-time constant, it should be able to be an initializer. I think this is a small drawback of CLang.
A function name is of course a compile-time constant.So this code works:
void func(void)
{
printf("func\n");
}
typedef void (*func_type)(void);
func_type f = func;
int main() {
f();
return 0;
}
You can also add underscore.js to your project and will be able to do it in one line:
_.map($("input[name='category_ids[]']:checked"), function(el){return $(el).val()})
Mockito offers a reflection-matcher:
For latest version of Mockito use:
Assert.assertTrue(new ReflectionEquals(expected, excludeFields).matches(actual));
For older versions use:
Assert.assertThat(actual, new ReflectionEquals(expected, excludeFields));
SQLite is created in your python directory where you installed the python.
I had the same error message, but these answers did not help. On a 4.3 nexus 7, I was using a user who was NOT the owner. I had uninstalled the older version but I kept getting the same message.
Solution: I had to login as the owner and go to Settings -> Apps, then swipe to the All tab. Scroll down to the very end of the list where the old versions are listed with a mark 'not installed'. Select it and press the 'settings' button in the top right corner and finally 'uninstall for all users'
The existing answers already cover the "how", but I just wanted to elaborate on the "what" and "why" for others who might be wondering.
What a compiler (gcc) does: The term "compile" is a bit of an overloaded term because it is used at a high-level to mean "convert source code to a program", but more technically means to "convert source code to object code". A compiler like gcc actually performs two related, but arguably distinct functions to turn your source code into a program: compiling (as in the latter definition of turning source to object code) and linking (the process of combining the necessary object code files together into one complete executable).
The original error that you saw is technically a "linking error", and is thrown by "ld", the linker. Unlike (strict) compile-time errors, there is no reference to source code lines, as the linker is already in object space.
By default, when gcc is given source code as input, it attempts to compile each and then link them all together. As noted in the other responses, it's possible to use flags to instruct gcc to just compile first, then use the object files later to link in a separate step. This two-step process may seem unnecessary (and probably is for very small programs) but it is very important when managing a very large program, where compiling the entire project each time you make a small change would waste a considerable amount of time.
If you want to be a good citizen, take the extra time to implement Parcelable since it will perform 10 times faster and use less resources.
However, in most cases, the slowness of Serializable won’t be noticeable. Feel free to use it but remember that serialization is an expensive operation so keep it to a minimum.
If you are trying to pass a list with thousands of serialized objects, it is possible that the whole process will take more than a second. It can make transitions or rotation from portrait to lanscape feel very sluggish.

Regarding your first question.The pipe works as follows:
numberValue | number: {minIntegerDigits}.{minFractionDigits}-{maxFractionDigits}
minFractionDigits: Minimum number of integer digits to show after the decimal point
maxFractionDigits: Maximum number of integer digits to show after the decimal point
2.Regarding your second question, Filter to zero decimal places as follows:
{{ numberValue | number: '1.0-0' }}

You want the mod operator.
The expression a Mod b is equivalent to the following formula:
a - (b * (a \ b))
Edited to add:
There are some special cases you may have to consider, because Excel is using floating point math (and returns a float
), which the VBA function returns an integer. Because of this, using mod
with floating-point numbers may require extra attention:
Excel's results may not correspond exactly with what you would predict; this is covered briefly here (see topmost answer) and at great length here.
As @André points out in the comments, negative numbers may round in the opposite direction from what you expect. The Fix()
function he suggests is explained here (MSDN).
Yes, your example would work fine.
As for exposing your classes, you can export
a class just like anything else:
class Animal {...}
module.exports = Animal;
Or the shorter:
module.exports = class Animal {
};
Once imported into another module, then you can treat it as if it were defined in that file:
var Animal = require('./Animal');
class Cat extends Animal {
...
}
You need to get the HLS m3u8 playlist files from the video's manifest. There are ways to do this by hand, but for simplicity I'll be using the youtube-dl tool to get this information. I'll be using this live stream as an example: https://www.youtube.com/watch?v=_Gtc-GtLlTk

In case anyone else runs into this problem, I was able to get it working like this:
var path = require('path');
// ...
resolve: {
root: [path.resolve(__dirname, 'src'), path.resolve(__dirname, 'node_modules')],
extensions: ['', '.js']
};
where my directory structure is:
.
+-- dist
+-- node_modules
+-- package.json
+-- README.md
+-- src
¦ +-- components
¦ +-- index.html
¦ +-- main.js
¦ +-- styles
+-- webpack.config.js
Then from anywhere in the src
directory I can call:
import MyComponent from 'components/MyComponent';
I came across this problem in Samsung S8 and N8 (havent found in any other)
so the problem is in the manifest file uses-permission
<uses-permission android:name="android.permission.CAMERA"
android:requiredFeature="true" />
For some reason, the attribute android:requiredFeature
is the culprit. and I haven't found the explanation on why.
to solve simply remove it,
<uses-permission android:name="android.permission.CAMERA" />
First, create staticfiles folder. Inside that folder create css, js, and img folder.
settings.py
import os
PROJECT_DIR = os.path.dirname(__file__)
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.sqlite3',
'NAME': os.path.join(PROJECT_DIR, 'myweblabdev.sqlite'),
'USER': '',
'PASSWORD': '',
'HOST': '',
'PORT': '',
}
}
MEDIA_ROOT = os.path.join(PROJECT_DIR, 'media')
MEDIA_URL = '/media/'
STATIC_ROOT = os.path.join(PROJECT_DIR, 'static')
STATIC_URL = '/static/'
STATICFILES_DIRS = (
os.path.join(PROJECT_DIR, 'staticfiles'),
)
main urls.py
from django.conf.urls import patterns, include, url
from django.conf.urls.static import static
from django.contrib import admin
from django.contrib.staticfiles.urls import staticfiles_urlpatterns
from myweblab import settings
admin.autodiscover()
urlpatterns = patterns('',
.......
) + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
urlpatterns += staticfiles_urlpatterns()
template
{% load static %}
<link rel="stylesheet" href="{% static 'css/style.css' %}">
This always works fine for me:
for url in list_of_urls:
urls.setdefault(url, 0)
urls[url] += 1
To run usually click and it should run, that is if you have java installed. If not get java from here
Sorry thought it was more general open a command prompt and type java -jar jbpm-installer-3.2.7.jar
Based on my experience, I add a method to dismiss me as extension to UIViewController:
extension UIViewController {
func dismissMe(animated: Bool, completion: (()->())?) {
var count = 0
if let c = self.navigationController?.viewControllers.count {
count = c
}
if count > 1 {
self.navigationController?.popViewController(animated: animated)
if let handler = completion {
handler()
}
} else {
dismiss(animated: animated, completion: completion)
}
}
}
Then I call this method to dismiss view controller in any UIViewController
subclass. For example, in cancel action:
class MyViewController: UIViewController {
...
@IBAction func cancel(sender: AnyObject) {
dismissMe(animated: true, completion: nil)
}
...
}
I ran into this problem today and wanted to share my solution. In my case, the solution was to delete the Child items before getting the Parent from the database.
Previously I was doing it like in the code below. I will then get the same error listed in this question.
var Parent = GetParent(parentId);
var children = Parent.Children;
foreach (var c in children )
{
Context.Children.Remove(c);
}
Context.SaveChanges();
What worked for me, is to get the children items first, using the parentId (foreign key) and then delete those items. Then I can get the Parent from the database and at that point, it should not have any children items anymore and I can add new children items.
var children = GetChildren(parentId);
foreach (var c in children )
{
Context.Children.Remove(c);
}
Context.SaveChanges();
var Parent = GetParent(parentId);
Parent.Children = //assign new entities/items here
I can think of doing it in two ways:
Storing the file in file system in any directory (say dir1
) and renaming it which ensures that the name is unique for every file (may be a timestamp) (say xyz123.jpg
), and then storing this name in some DataBase. Then while generating the JSON you pull this filename and generate a complete URL (which will be http://example.com/dir1/xyz123.png
)and insert it in the JSON.
Base 64 Encoding, It's basically a way of encoding arbitrary binary data in ASCII text. It takes 4 characters per 3 bytes of data, plus potentially a bit of padding at the end. Essentially each 6 bits of the input is encoded in a 64-character alphabet. The "standard" alphabet uses A-Z, a-z, 0-9 and + and /, with = as a padding character. There are URL-safe variants. So this approach will allow you to put your image directly in the MongoDB, while storing it Encode the image and decode while fetching it, it has some of its own drawbacks:
A.) Canvas
Load the image into an Image-Object, paint it to a canvas and convert the canvas back to a dataURL.
function convertToDataURLviaCanvas(url, callback, outputFormat){
var img = new Image();
img.crossOrigin = 'Anonymous';
img.onload = function(){
var canvas = document.createElement('CANVAS');
var ctx = canvas.getContext('2d');
var dataURL;
canvas.height = this.height;
canvas.width = this.width;
ctx.drawImage(this, 0, 0);
dataURL = canvas.toDataURL(outputFormat);
callback(dataURL);
canvas = null;
};
img.src = url;
}
Usage
convertToDataURLviaCanvas('http://bit.ly/18g0VNp', function(base64Img){
// Base64DataURL
});
Supported input formats
image/png
, image/jpeg
, image/jpg
, image/gif
, image/bmp
, image/tiff
, image/x-icon
, image/svg+xml
, image/webp
, image/xxx
B.) FileReader
Load the image as blob via XMLHttpRequest and use the FileReader API to convert it to a data URL.
function convertFileToBase64viaFileReader(url, callback){
var xhr = new XMLHttpRequest();
xhr.responseType = 'blob';
xhr.onload = function() {
var reader = new FileReader();
reader.onloadend = function () {
callback(reader.result);
}
reader.readAsDataURL(xhr.response);
};
xhr.open('GET', url);
xhr.send();
}
This approach
Usage
convertFileToBase64viaFileReader('http://bit.ly/18g0VNp', function(base64Img){
// Base64DataURL
});
I came across this question when I was trying to find multiple filenames that I could not combine into a regular expression as described in @Chris J's answer, here is what worked for me
find . -name one.pdf -o -name two.txt -o -name anotherone.jpg
-o
or -or
is logical OR. See Finding Files on Gnu.org for more information.
I was running this on CygWin.
Another veneration of find_elements_by_xpath(".//*")
is:

find_elements(By.XPATH, ".//*")
A simple change in Num2 class like this:
super().__init__(num)
It works in python3.
class Num:
def __init__(self,num):
self.n1 = num
class Num2(Num):
def __init__(self,num):
super().__init__(num)
self.n2 = num*2
def show(self):
print (self.n1,self.n2)
mynumber = Num2(8)
mynumber.show()
Having been bitten by this, I have a habit of including locally defined variables in the innermost scope which I use to transfer to any closure. In your example:
foreach (var s in strings)
query = query.Where(i => i.Prop == s); // access to modified closure
I do:
foreach (var s in strings)
{
string search = s;
query = query.Where(i => i.Prop == search); // New definition ensures unique per iteration.

Once you have that habit, you can avoid it in the very rare case you actually intended to bind to the outer scopes. To be honest, I don't think I have ever done so.
In the past, I've used a .cmd script I found on the Internet. I hate the way localization normally messes with dates. Anytime you have dates in filenames (or anywhere else, if I may be so bold) I figure you want them in ISO 8601 format:
2015-02-19T14:54:51Z
or something else that has Y M D H M in that order, such as
2015-02-19 14:54
because it fixes the MDY / DMY ambiguity and because it's sortable as text.
I don't know where I got that .cmd script, but it may have been http://ss64.com/nt/syntax-getdate.html, which works beautifully on my YYYY-MM-DD Windows 8.1 and on a M/D/YYYY vanilla install of Windows 7. Both give the same format:

Just an addition to @Andy Hayden's answer:
Since DataFrame.mask
is the opposite twin of DataFrame.where
, they have the exactly same signature but with opposite meaning:
DataFrame.where
is useful for Replacing values where the condition is False. DataFrame.mask
is used for Replacing values where the condition is True.So in this question, using df.mask(df.isna(), other=None, inplace=True)
might be more intuitive.
In Modern OpenGL(OpenGL 3.2 and higher), you could use a Geometry Shader for this :
#version 330
layout (triangles) in;
layout (line_strip /*for lines, use "points" for points*/, max_vertices=3) out;
in vec2 texcoords_pass[]; //Texcoords from Vertex Shader
in vec3 normals_pass[]; //Normals from Vertex Shader
out vec3 normals; //Normals for Fragment Shader
out vec2 texcoords; //Texcoords for Fragment Shader
void main(void)
{
int i;
for (i = 0; i < gl_in.length(); i++)
{
texcoords=texcoords_pass[i]; //Pass through
normals=normals_pass[i]; //Pass through
gl_Position = gl_in[i].gl_Position; //Pass through
EmitVertex();
}
EndPrimitive();
}
Notices :
layout (line_strip, max_vertices=3) out;
to layout (points, max_vertices=3) out;
Try this...
* {
transition: all .2s linear;
-webkit-transition: all .2s linear;

a {
-webkit-transition: background-position 1ms linear;
-moz-transition: background-position 1ms linear;
-o-transition: background-position 1ms linear;
transition: background-position 1ms linear;
}
The S parameter does not do anything on its own.
/S Modifies the treatment of string after /C or /K (see below)
/C Carries out the command specified by string and then terminates
/K Carries out the command specified by string but remains
Try something like this instead
Call Shell("cmd.exe /S /K" & "perl a.pl c:\temp", vbNormalFocus)
You may not even need to add "cmd.exe" to this command unless you want a command window to open up when this is run. Shell should execute the command on its own.
Shell("perl a.pl c:\temp")
-Edit-
To wait for the command to finish you will have to do something like @Nate Hekman shows in his answer here
Dim wsh As Object
Set wsh = VBA.CreateObject("WScript.Shell")
Dim waitOnReturn As Boolean: waitOnReturn = True
Dim windowStyle As Integer: windowStyle = 1
wsh.Run "cmd.exe /S /C perl a.pl c:\temp", windowStyle, waitOnReturn
Fundamentally you hadn't declare location which is what nginx uses to bind URL with resources.
server {
listen 80;
server_name localhost;
access_log logs/localhost.access.log main;
location / {

index index.html index.htm index.php;
}
}
This site uses the method isEmpty()

Set nextCell = currentCell.Offset(1, 0)
If nextCell.Value = currentCell.Value Then
currentCell.EntireRow.Delete

In the first step the data in the first column from Sheet1 will be sort. In the second step, all rows with same data will be removed.
Create links using JavaScript:
<script language="javascript">
<!--
document.write("<a href=\"www.example.com\">");
document.write("Your Title");
document.write("</a>");
//-->
</script>
OR
<script type="text/javascript">
document.write('Your Title'.link('http://www.example.com'));
</script>
OR
<script type="text/javascript">
newlink = document.createElement('a');
newlink.innerHTML = 'Google';
newlink.setAttribute('title', 'Google');
newlink.setAttribute('href', 'http://google.com');
document.body.appendChild(newlink);
</script>
I encountered the same problem and checked for null but it did not help. Because the script was loading before page load. So just by placing the script before the end body tag solved the problem.
To create Anaconda Prompt using Command Prompt, just create a shortcut file of Command Prompt and modify the shortcut target to:
%windir%\System32\cmd.exe "/K" <Anaconda Location>\anaconda3\Scripts\activate.bat
Example:
%windir%\system32\cmd.exe "/K" C:\Users\user_1\AppData\Local\Continuum\anaconda3\Scripts\activate.bat

The following Javascript snippet works in Chrome by using the new 'download' attribute of links and simulating a click.
function downloadWithName(uri, name) {

link.click();
}
And the following example shows it's use:

It's not fading to "black transparent" or "white transparent". It's just showing whatever color is "behind" the image, which is not the image's background color - that color is completely hidden by the image.
If you want to fade to black(ish), you'll need a black container around the image. Something like:
.ctr {
margin: 0;
padding: 0;
background-color: black;
display: inline-block;
}
and
<div class="ctr"><img ... /></div>
Another, unfortunately highly OS-dependent, solution is memory mapping the file. The benefits generally include performance of the read, and reduced memory use as the applications view and operating systems file cache can actually share the physical memory.
POSIX code would look like this:
int fd = open("filename", O_RDONLY);
int len = lseek(fd, 0, SEEK_END);
void *data = mmap(0, len, PROT_READ, MAP_PRIVATE, fd, 0);
Windows on the other hand is little more tricky, and unfortunately I don't have a compiler in front of me to test, but the functionality is provided by CreateFileMapping()
and MapViewOfFile()
.
To solve the problem I use ${string_prompt} variable. It shows a input dialog when application runs. I can set the date/time manually at that dialog.

CORS support in Tomcat is provided via a filter. You need to add this filter to your web.xml
file and configure it to match your requirements. Full details on the configuration options available can be found in the Tomcat Documentation.
It depends on how the data was initially put into the column. Try either of these as one should work:
SELECT CONVERT(NVarChar(40), BLOBTextToExtract)
FROM [NavisionSQL$Customer];
Or if it was just varchar
...
SELECT CONVERT(VarChar(40), BLOBTextToExtract)
FROM [NavisionSQL$Customer];
I used this script to verify and test on SQL Server 2K8 R2:
DECLARE @blob VarBinary(MAX) = CONVERT(VarBinary(MAX), 'test');
-- show the binary representation
SELECT @blob;
-- this doesn't work
SELECT CONVERT(NVarChar(100), @blob);
-- but this does
SELECT CONVERT(VarChar(100), @blob);
Should be:

WHEN COUNT(*)< 12 THEN 'Best'
ELSE 'Outstanding'

I might have a solution for the video as background, stretched to the browser-width or height, (but the video will still preserve the aspect ratio, couldnt find a solution for that yet.):
Put the video right after the body-tag with style="width:100%;"
.
Right afterwords, put a "bodydummy"-tag:
<body>
<video id="bgVideo" autoplay poster="videos/poster.png">
<source src="videos/test-h264-640x368-highqual-winff.mp4" type="video/mp4"/>
<source src="videos/test-640x368-webmvp8-miro.webm" type="video/webm"/>
<source src="videos/test-640x368-theora-miro.ogv" type="video/ogg"/>
</video>
<img id="bgImg" src="videos/poster.png" />
<!-- This image stretches exactly to the browser width/height and lies behind the video-->
<div id="bodyDummy">
Put all your content inside the bodydummy
-div and put the z-indexes correctly in CSS like this:
#bgImg{
position: absolute;
top: 0;
left: 0;
border: 0;
z-index: 1;
width: 100%;
height: 100%;
}
#bgVideo{
position: absolute;
top: 0;
left: 0;
border: 0;
z-index: 2;
width: 100%;
height: 100%;
}
#bodyDummy{
position: absolute;
top: 0;
left: 0;
z-index: 3;
overflow: auto;
width: 100%;
height: 100%;
}
Hope I could help. Let me know when you could find a solution that the video does not maintain the aspect ratio, so it could fill the whole browser window so we do not have to put a bgimage.
What is the code of your button? If it's an a tag, then you could do this:
a {_x000D_
padding: 5px;_x000D_
background: green;_x000D_
}_x000D_
a:visited {_x000D_
background: red;_x000D_
}
_x000D_
<a href="#">A button</a>
_x000D_
Or you could use jQuery to add a class on click, as below:
$("#button").click(function() {_x000D_
$("#button").addClass('button-clicked');_x000D_
});
_x000D_
.button-clicked {_x000D_
background: red;_x000D_
}
_x000D_
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<button id="button">Button</button>
_x000D_
To switch to root so that all subsequent commands are executed with high privileges instead of using sudo
before each command use following command and then provide the password when prompted.
sudo -i

Here's what I get.
I'm using Visual Studio Code and its Terminal to execute the 'npm' commands.
Visual Studio Code (not as administrator)
PS g:\labs\myproject> npm install bootstrap@3
Results in scandir and/or permission errors.
Visual Studio Code (as Administrator)
Run this command after I've run something like 'ng serve'
PS g:\labs\myproject> npm install bootstrap@3
Results in scandir and/or permission errors.
Visual Studio Code (as Administrator - closing and opening the IDE)
If I have already executed other commands that would impact node modules I decided to try closing Visual Studio Code first, opening it up as Administrator then running the command:
PS g:\labs\myproject> npm install bootstrap@3
Result I get then is: + [email protected]
added 115 packages and updated 1 package in 24.685s
This is not a permanent solution since I don't want to continue closing down VS Code every time I want to execute an npm command, but it did resolve the issue to a point.
An alternative way to get only one character.
$str = 'abcdefghij';
echo $str{5};
I would particularly not use this, but for the purpose of education. We can use that to answer the question:
$newString = '';
for ($i = 0; $i < 5; $i++) {
$newString .= $str{$i};
}
echo $newString;
For anyone using that. Bear in mind curly brace syntax for accessing array elements and string offsets is deprecated from PHP 7.4

I really liked adamk's answer, suggesting that you use glob()
, from the module of the same name. This allows you to have pattern matching with *
s.
But as other people pointed out in the comments, glob()
can get tripped up over inconsistent slash directions. To help with that, I suggest you use the join()
and expanduser()
functions in the os.path
module, and perhaps the getcwd()
function in the os
module, as well.
As examples:
from glob import glob
# Return everything under C:\Users\admin that contains a folder called wlp.
glob('C:\Users\admin\*\wlp')
The above is terrible - the path has been hardcoded and will only ever work on Windows between the drive name and the \
s being hardcoded into the path.
from glob import glob
from os.path import join
# Return everything under Users, admin, that contains a folder called wlp.
glob(join('Users', 'admin', '*', 'wlp'))
The above works better, but it relies on the folder name Users
which is often found on Windows and not so often found on other OSs. It also relies on the user having a specific name, admin
.
from glob import glob
from os.path import expanduser, join
# Return everything under the user directory that contains a folder called wlp.
glob(join(expanduser('~'), '*', 'wlp'))
This works perfectly across all platforms.
Another great example that works perfectly across platforms and does something a bit different:
from glob import glob
from os import getcwd
from os.path import join
# Return everything under the current directory that contains a folder called wlp.
glob(join(getcwd(), '*', 'wlp'))
Hope these examples help you see the power of a few of the functions you can find in the standard Python library modules.
Sometimes it is not eligible to set height to pixel values.
However, it is possible to show vertical scrollbar through setting height of div to 100%
and overflow
to auto
.
Let me show an example:
<div id="content" style="height: 100%; overflow: auto">
<p>some text</p>
<ul>
<li>text</li>
.....
<li>text</li>
</div>
400 Bad Request would now seem to be the best HTTP/1.1 status code for your use case.
At the time of your question (and my original answer), RFC 7231 was not a thing; at which point I objected to 400 Bad Request
because RFC 2616 said (with emphasis mine):
The request could not be understood by the server due to malformed syntax.
and the request you describe is syntactically valid JSON encased in syntactically valid HTTP, and thus the server has no issues with the syntax of the request.
However as pointed out by Lee Saferite in the comments, RFC 7231, which obsoletes RFC 2616, does not include that restriction:
The 400 (Bad Request) status code indicates that the server cannot or will not process the request due to something that is perceived to be a client error (e.g., malformed request syntax, invalid request message framing, or deceptive request routing).
However, prior to that re-wording (or if you want to quibble about RFC 7231 only being a proposed standard right now), 422 Unprocessable Entity
does not seem an incorrect HTTP status code for your use case, because as the introduction to RFC 4918 says:
While the status codes provided by HTTP/1.1 are sufficient to describe most error conditions encountered by WebDAV methods, there are some errors that do not fall neatly into the existing categories. This specification defines extra status codes developed for WebDAV methods (Section 11)
And the description of 422
says:
The 422 (Unprocessable Entity) status code means the server understands the content type of the request entity (hence a 415(Unsupported Media Type) status code is inappropriate), and the syntax of the request entity is correct (thus a 400 (Bad Request) status code is inappropriate) but was unable to process the contained instructions.
(Note the reference to syntax; I suspect 7231 partly obsoletes 4918 too)
This sounds exactly like your situation, but just in case there was any doubt, it goes on to say:
For example, this error condition may occur if an XML request body contains well-formed (i.e., syntactically correct), but semantically erroneous, XML instructions.
(Replace "XML" with "JSON" and I think we can agree that's your situation)
Now, some will object that RFC 4918 is about "HTTP Extensions for Web Distributed Authoring and Versioning (WebDAV)" and that you (presumably) are doing nothing involving WebDAV so shouldn't use things from it.
Given the choice between using an error code in the original standard that explicitly doesn't cover the situation, and one from an extension that describes the situation exactly, I would choose the latter.
Furthermore, RFC 4918 Section 21.4 refers to the IANA Hypertext Transfer Protocol (HTTP) Status Code Registry, where 422 can be found.
I propose that it is totally reasonable for an HTTP client or server to use any status code from that registry, so long as they do so correctly.
But as of HTTP/1.1, RFC 7231 has traction, so just use 400 Bad Request
!
PARTITION BY
segregate sets, this enables you to be able to work(ROW_NUMBER(),COUNT(),SUM(),etc) on related set independently.
In your query, the related set comprised of rows with similar cdt.country_code, cdt.account, cdt.currency. When you partition on those columns and you apply ROW_NUMBER on them. Those other columns on those combination/set will receive sequential number from ROW_NUMBER
But that query is funny, if your partition by some unique data and you put a row_number on it, it will just produce same number. It's like you do an ORDER BY on a partition that is guaranteed to be unique. Example, think of GUID as unique combination of cdt.country_code, cdt.account, cdt.currency
newid()
produces GUID, so what shall you expect by this expression?
select
hi,ho,
row_number() over(partition by newid() order by hi,ho)
from tbl;
...Right, all the partitioned(none was partitioned, every row is partitioned in their own row) rows' row_numbers are all set to 1
Basically, you should partition on non-unique columns. ORDER BY on OVER needed the PARTITION BY to have a non-unique combination, otherwise all row_numbers will become 1
An example, this is your data:
create table tbl(hi varchar, ho varchar);
insert into tbl values
('A','X'),
('A','Y'),
('A','Z'),
('B','W'),
('B','W'),
('C','L'),
('C','L');
Then this is analogous to your query:
select
hi,ho,
row_number() over(partition by hi,ho order by hi,ho)
from tbl;
What will be the output of that?
HI HO COLUMN_2
A X 1
A Y 1
A Z 1
B W 1
B W 2
C L 1
C L 2
You see thee combination of HI HO? The first three rows has unique combination, hence they are set to 1, the B rows has same W, hence different ROW_NUMBERS, likewise with HI C rows.
Now, why is the ORDER BY
needed there? If the previous developer merely want to put a row_number on similar data (e.g. HI B, all data are B-W, B-W), he can just do this:
select
hi,ho,
row_number() over(partition by hi,ho)
from tbl;
But alas, Oracle(and Sql Server too) doesn't allow partition with no ORDER BY
; whereas in Postgresql, ORDER BY
on PARTITION is optional: http://www.sqlfiddle.com/#!1/27821/1
select
hi,ho,
row_number() over(partition by hi,ho)
from tbl;
Your ORDER BY
on your partition look a bit redundant, not because of the previous developer's fault, some database just don't allow PARTITION
with no ORDER BY
, he might not able find a good candidate column to sort on. If both PARTITION BY columns and ORDER BY columns are the same just remove the ORDER BY, but since some database don't allow it, you can just do this:
SELECT cdt.*,
ROW_NUMBER ()
OVER (PARTITION BY cdt.country_code, cdt.account, cdt.currency
ORDER BY newid())
seq_no
FROM CUSTOMER_DETAILS cdt
You cannot find a good column to use for sorting similar data? You might as well sort on random, the partitioned data have the same values anyway. You can use GUID for example(you use newid()
for SQL Server). So that has the same output made by previous developer, it's unfortunate that some database doesn't allow PARTITION
with no ORDER BY
Though really, it eludes me and I cannot find a good reason to put a number on the same combinations (B-W, B-W in example above). It's giving the impression of database having redundant data. Somehow reminded me of this: How to get one unique record from the same list of records from table? No Unique constraint in the table
It really looks arcane seeing a PARTITION BY with same combination of columns with ORDER BY, can not easily infer the code's intent.
Live test: http://www.sqlfiddle.com/#!3/27821/6
But as dbaseman have noticed also, it's useless to partition and order on same columns.
You have a set of data like this:
create table tbl(hi varchar, ho varchar);
insert into tbl values
('A','X'),
('A','X'),
('A','X'),
('B','Y'),
('B','Y'),
('C','Z'),
('C','Z');
Then you PARTITION BY hi,ho; and then you ORDER BY hi,ho. There's no sense numbering similar data :-) http://www.sqlfiddle.com/#!3/29ab8/3
select
hi,ho,
row_number() over(partition by hi,ho order by hi,ho) as nr
from tbl;
Output:
HI HO ROW_QUERY_A
A X 1
A X 2
A X 3
B Y 1
B Y 2
C Z 1
C Z 2
See? Why need to put row numbers on same combination? What you will analyze on triple A,X, on double B,Y, on double C,Z? :-)
You just need to use PARTITION on non-unique column, then you sort on non-unique column(s)'s unique-ing column. Example will make it more clear:
create table tbl(hi varchar, ho varchar);
insert into tbl values
('A','D'),
('A','E'),
('A','F'),
('B','F'),
('B','E'),
('C','E'),
('C','D');
select
hi,ho,
row_number() over(partition by hi order by ho) as nr
from tbl;
PARTITION BY hi
operates on non unique column, then on each partitioned column, you order on its unique column(ho), ORDER BY ho
Output:
HI HO NR
A D 1
A E 2
A F 3
B E 1
B F 2
C D 1
C E 2
That data set makes more sense
Live test: http://www.sqlfiddle.com/#!3/d0b44/1
And this is similar to your query with same columns on both PARTITION BY and ORDER BY:
select
hi,ho,
row_number() over(partition by hi,ho order by hi,ho) as nr
from tbl;
And this is the ouput:
HI HO NR
A D 1
A E 1
A F 1
B E 1
B F 1
C D 1
C E 1
See? no sense?
Live test: http://www.sqlfiddle.com/#!3/d0b44/3
Finally this might be the right query:
SELECT cdt.*,
ROW_NUMBER ()
OVER (PARTITION BY cdt.country_code, cdt.account -- removed: cdt.currency
ORDER BY
-- removed: cdt.country_code, cdt.account,
cdt.currency) -- keep
seq_no
FROM CUSTOMER_DETAILS cdt
Long time ago I did this in Java and found someone else's solution based on a single string that captures part of the Unicode table that was important for the conversion - the rest was converted to ? or any other replacement character. So I tried to convert it to JavaScript. Mind that I'm no JS expert. :-)
TAB_00C0 = "AAAAAAACEEEEIIII" +
"DNOOOOO*OUUUUYIs" +
"aaaaaaaceeeeiiii" +
"?nooooo/ouuuuy?y" +
"AaAaAaCcCcCcCcDd" +
"DdEeEeEeEeEeGgGg" +
"GgGgHhHhIiIiIiIi" +
"IiJjJjKkkLlLlLlL" +
"lLlNnNnNnnNnOoOo" +
"OoOoRrRrRrSsSsSs" +
"SsTtTtTtUuUuUuUu" +
"UuUuWwYyYZzZzZzF";
function stripDiacritics(source) {
var result = source.split('');
for (var i = 0; i < result.length; i++) {
var c = source.charCodeAt(i);
if (c >= 0x00c0 && c <= 0x017f) {
result[i] = String.fromCharCode(TAB_00C0.charCodeAt(c - 0x00c0));
} else if (c > 127) {
result[i] = '?';
}
}
return result.join('');
}
stripDiacritics("Šupa, co? lštcžýæøåHð")
This converts most of latin1+2 Unicode characters. It is not able to translate single char to multiple. I don't know its performance on JS, in Java this is by far the fastest of common solutions (6-50x), there is no map, there is no regex, nothing. It produces strict ASCII output, potentially with a loss of information, but the size of the output matches the input.
I tested the snippet with http://www.webtoolkitonline.com/javascript-tester.html and it produced Supa, co? lstczyaoa??
as expected.
You can always use the 'pre' tag inside the label, and just enter the blank spaces in it, So you can always add the same or different number of spaces you require
<form>
<label>First Name :<pre>Here just enter number of spaces you want to use(I mean using spacebar to enter blank spaces)</pre>
<input type="text"></label>
<label>Last Name :<pre>Now Enter enter number of spaces to match above number of
spaces</pre>
<input type="text"></label>
</form>

Make sure that you have installed the correct NuGet package
in your console application:
<package id="Microsoft.AspNet.WebApi.Client" version="4.0.20710.0" />
and that you are targeting at least .NET 4.0.
This being said, your GetAllFoos
function is defined to return an IEnumerable<Prospect>
whereas in your ReadAsAsync
method you are passing IEnumerable<Foo>
which obviously are not compatible types.

Just add weightSum
tag to linearlayout
to 1 and for the corresponding view beneath it give layout_weight
as .9 it will create a space between the views. You can experiment with the values to get appropriate value for you.
You can create a thread just like this:
Thread thread = new Thread(new Runnable() {
public void run() {
}
});
thread.start();
Also, you can use Runnable, Asyntask, Timer, TimerTaks and AlarmManager to excecute Threads.
Not sure if this is valid but it worked for me.

<div style='position:relative;background-color:#000000;width:600px;height:30px;border:solid;'>_x000D_
<p style='display:inline;color:#ffffff;float:left;'> Whatever </p> _x000D_
<a style='position:absolute;top:0px;left:0px;width:100%;height:100%;display:inline;' href ='#'></a>_x000D_
</div>
_x000D_
I have create an extension method based on position of items in a list which is bind with recycler view
Smooth scroll in large list takes longer time to scroll , use this to improve speed of scrolling and also have the smooth scroll animation. Cheers!!
fun RecyclerView?.perfectScroll(size: Int,up:Boolean = true ,smooth: Boolean = true) {
this?.apply {
if (size > 0) {
if (smooth) {
val minDirectScroll = 10 // left item to scroll
//smooth scroll
if (size > minDirectScroll) {
//scroll directly to certain position
val newSize = if (up) minDirectScroll else size - minDirectScroll
//scroll to new position
val newPos = newSize - 1
//direct scroll
scrollToPosition(newPos)
//smooth scroll to rest
perfectScroll(minDirectScroll, true)
} else {
//direct smooth scroll
smoothScrollToPosition(if (up) 0 else size-1)
}
} else {
//direct scroll
scrollToPosition(if (up) 0 else size-1)
}
}
} }
Just call the method anywhere using
rvList.perfectScroll(list.size,up=true,smooth=true)
Given the interface:
public interface IAnything {
int i;
void m1();
void m2();
void m3();
}
This is how Java actually sees it:
public interface IAnything {
public static final int i;
public abstract void m1();
public abstract void m2();
public abstract void m3();
}
So you can leave some (or all) of these abstract
methods unimplemented, just as you would do in the case of abstract
classes extending another abstract
class.
When you implement
an interface
, the rule that all interface
methods must be implemented in the derived class
, applies only to concrete class
implementation (i.e., which isn't abstract
itself).
If you indeed plan on creating an abstract class
out of it, then there is no rule that says you've to implement
all the interface
methods (note that in such a case it is mandatory to declare the derived class
as abstract
)
Although the accepted answer works perfectly, the solution below uses addOnScrollListener since setOnScrollListener is deprecated, and reduces number of variables, and if conditions.
final LinearLayoutManager layoutManager = new LinearLayoutManager(context);
feedsRecyclerView.setLayoutManager(layoutManager);
feedsRecyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() {
@Override
public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
super.onScrolled(recyclerView, dx, dy);
if (dy > 0) {
if ((layoutManager.getChildCount() + layoutManager.findFirstVisibleItemPosition()) >= layoutManager.getItemCount()) {
Log.d("TAG", "End of list");
//loadMore();
}
}
}
});
You can use DISTINCT
like that
mysql_query("SELECT DISTINCT(ticket_id), column1, column2, column3
FROM temp_tickets
ORDER BY ticket_id");
This might be an old qustion, but just to keep things updated, there is a forEach method in javascript that works with NodeJS. Here's the link from the docs. And an example:
count = countElements.length;
if (count > 0) {
countElements.forEach(function(countElement){
console.log(countElement);
});
}
The issue of EOLs in mixed-platform projects has been making my life miserable for a long time. The problems usually arise when there are already files with different and mixed EOLs already in the repo. This means that:
CRLF
and LF
in the same file.How this happens is not the issue here, but it does happen.
I ran some conversion tests on Windows for the various modes and their combinations.
Here is what I got, in a slightly modified table:
| Resulting conversion when | Resulting conversion when | committing files with various | checking out FROM repo - | EOLs INTO repo and | with mixed files in it and | core.autocrlf value: | core.autocrlf value: -------------------------------------------------------------------------------- File | true | input | false | true | input | false -------------------------------------------------------------------------------- Windows-CRLF | CRLF -> LF | CRLF -> LF | as-is | as-is | as-is | as-is Unix -LF | as-is | as-is | as-is | LF -> CRLF | as-is | as-is Mac -CR | as-is | as-is | as-is | as-is | as-is | as-is Mixed-CRLF+LF | as-is | as-is | as-is | as-is | as-is | as-is Mixed-CRLF+LF+CR | as-is | as-is | as-is | as-is | as-is | as-is
As you can see, there are 2 cases when conversion happens on commit (3 left columns). In the rest of the cases the files are committed as-is.
Upon checkout (3 right columns), there is only 1 case where conversion happens when:
core.autocrlf
is true
and LF
EOL.Most surprising for me, and I suspect, the cause of many EOL problems is that there is no configuration in which mixed EOL like CRLF
+LF
get normalized.
Note also that "old" Mac EOLs of CR
only also never get converted.
This means that if a badly written EOL conversion script tries to convert a mixed ending file with CRLF
s+LF
s, by just converting LF
s to CRLF
s, then it will leave the file in a mixed mode with "lonely" CR
s wherever a CRLF
was converted to CRCRLF
.
Git will then not convert anything, even in true
mode, and EOL havoc continues. This actually happened to me and messed up my files really badly, since some editors and compilers (e.g. VS2010) don't like Mac EOLs.
I guess the only way to really handle these problems is to occasionally normalize the whole repo by checking out all the files in input
or false
mode, running a proper normalization and re-committing the changed files (if any). On Windows, presumably resume working with core.autocrlf true
.
Try wrapping your FileWriter
in a BufferedWriter
:
BufferedWriter bw = new BufferedWriter(writer);
bw.newLine();

I had the following problem(s) with the existing answers to this question (and variations of this question on other stackoverflow threads):
Or, slightly more accurately:
My final solution, which loads the script before returning, AND has all scripts properly accessible in the debugger (for Chrome at least) is as follows:
WARNING: The following code should PROBABLY be used only in 'development' mode. (For 'release' mode I recommend prepackaging and minification WITHOUT dynamic script loading, or at least without eval).
//Code User TODO: you must create and set your own 'noEval' variable
require = function require(inFileName)
{
var aRequest
,aScript
,aScriptSource
;
//setup the full relative filename
inFileName =
window.location.protocol + '//'
+ window.location.host + '/'
+ inFileName;
//synchronously get the code
aRequest = new XMLHttpRequest();
aRequest.open('GET', inFileName, false);
aRequest.send();
//set the returned script text while adding special comment to auto include in debugger source listing:
aScriptSource = aRequest.responseText + '\n////# sourceURL=' + inFileName + '\n';
if(noEval)//<== **TODO: Provide + set condition variable yourself!!!!**
{
//create a dom element to hold the code
aScript = document.createElement('script');
aScript.type = 'text/javascript';
//set the script tag text, including the debugger id at the end!!
aScript.text = aScriptSource;
//append the code to the dom
document.getElementsByTagName('body')[0].appendChild(aScript);
}
else
{
eval(aScriptSource);
}
};
in SQL*Plus you could also use a REFCURSOR
variable:
SQL> VARIABLE x REFCURSOR

You should use the overloaded sort(peps, new People()) method
import java.util.ArrayList;
import java.util.Collections;
import java.util.Comparator;
import java.util.List;
public class Test
{
public static void main(String[] args)

List<People> peps = new ArrayList<>();
peps.add(new People(123, "M", 14.25));
peps.add(new People(234, "M", 6.21));
peps.add(new People(362, "F", 9.23));
peps.add(new People(111, "M", 65.99));
peps.add(new People(535, "F", 9.23));
Collections.sort(peps, new People().new ComparatorId());
for (int i = 0; i < peps.size(); i++)
{
System.out.println(peps.get(i));
}
}
}
class People
{
private int id;
private String info;
private double price;
public People()
{
}
public People(int newid, String newinfo, double newprice) {
setid(newid);
setinfo(newinfo);
setprice(newprice);
}
public int getid() {
return id;

public void setid(int id) {
this.id = id;

return info;
}
public void setinfo(String info) {
this.info = info;

public double getprice() {
return price;
}
public void setprice(double price) {
this.price = price;
}
class ComparatorId implements Comparator<People>
{
@Override
public int compare(People obj1, People obj2) {
Integer p1 = obj1.getid();
Integer p2 = obj2.getid();
if (p1 > p2) {
return 1;
} else if (p1 < p2){

You can use following script :
Declare @Cons_Name NVARCHAR(100)
Declare @Str NVARCHAR(500)
SELECT @Cons_Name=name
FROM sys.objects
WHERE type='UQ' AND OBJECT_NAME(parent_object_id) = N'TableName';
---- Delete the unique constraint.
SET @Str='ALTER TABLE TableName DROP CONSTRAINT ' + @Cons_Name;

Here are 4 ways to insert data into a table.
Simple insertion when the table column sequence is known.
INSERT INTO Table1 VALUES (1,2,...)
Simple insertion into specified columns of the table.
INSERT INTO Table1(col2,col4) VALUES (1,2)
Bulk insertion when...
INSERT INTO Table1 {Column sequence} SELECT * FROM Table2
Bulk insertion of selected data into specified columns of Table2.
.
INSERT INTO Table1 (Column1,Column2 ....)
SELECT Column1,Column2...
FROM Table2
Browser have cross domain security at client side which verify that server allowed to fetch data from your domain. If Access-Control-Allow-Origin
not available in response header, browser disallow to use response in your JavaScript code and throw exception at network level. You need to configure cors
at your server side.
You can fetch request using mode: 'cors'
. In this situation browser will not throw execption for cross domain, but browser will not give response in your javascript function.
So in both condition you need to configure cors
in your server or you need to use custom proxy server.
ffmpeg provides this functionality. All you need to do is run someting like
ffmpeg -i <inputfilename> -s 640x480 -b 512k -vcodec mpeg1video -acodec copy <outputfilename>
For newer versions of ffmpeg you need to change -b
to -b:v
:
ffmpeg -i <inputfilename> -s 640x480 -b:v 512k -vcodec mpeg1video -acodec copy <outputfilename>
to convert the input video file to a video with a size of 640 x 480 and a bitrate of 512 kilobits/sec using the MPEG 1 video codec and just copying the original audio stream. Of course, you can plug in any values you need and play around with the size and bitrate to achieve the quality/size tradeoff you are looking for. There are also a ton of other options described in the documentation
Run ffmpeg -formats
or ffmpeg -codecs
for a list of all of the available formats and codecs. If you don't have to target a specific codec for the final output, you can achieve better compression ratios with minimal quality loss using a state of the art codec like H.264.
Assuming you can arrange to have a container element you wish to fill, this appears to work, but feels a bit hackish. In essence, I just use min/max-width/height
on a larger area and then scale that area back into the original dimensions.

To use getSingleResult on a TypedQuery you can use
query.setFirstResult(0);
query.setMaxResults(1);
result = query.getSingleResult();
You could run jconsole
(included with Java 6's SDK) then connect to your Java application. It will show you every Thread running and its stack trace.

I've tried all the possible solutions but nothing worked for local video bindings. I believe best solution would be to fix using jQuery if you still wants to use iframes.
$(document).ready(function () {
var ownVideos = $("iframe");
$.each(ownVideos, function (i, video) {
var frameContent = $(video).contents().find('body').html();
if (frameContent) {
$(video).contents().find('body').html(frameContent.replace("autoplay", ""));
}
});
});
Note: It'll find all the iframes on document ready and loop through each iframe contents and replace/remove autoplay
attribute. This solution can be use anywhere in your project. If you would like to do for specific element then use the code under $.each
function and replace $(video)
with your iframe element id like $("#myIFrameId")
.
myList.Any(myString.Contains);
This should do it:
//Returns the index of the first occurence of char c in char* string. If not found -1 is returned.
int get_index(char* string, char c) {
char *e = strchr(string, c);
if (e == NULL) {
return -1;
}
return (int)(e - string);
}
MySQL really dislikes mixing collations unless it can coerce them to the same one (which clearly is not feasible in your case). Can't you just force the same collation to be used via a COLLATE clause? (or the simpler BINARY
shortcut if applicable...).
In Java 7 and higher you can use listdir
Path dir = ...;
try (DirectoryStream<Path> stream = Files.newDirectoryStream(dir)) {
for (Path file: stream) {
System.out.println(file.getFileName());
}
} catch (IOException | DirectoryIteratorException x) {
// IOException can never be thrown by the iteration.
// In this snippet, it can only be thrown by newDirectoryStream.
System.err.println(x);
}
You can also create a filter that can then be passed into the newDirectoryStream
method above
DirectoryStream.Filter<Path> filter = new DirectoryStream.Filter<Path>() {
public boolean accept(Path file) throws IOException {
try {
return (Files.isRegularFile(path));
} catch (IOException x) {
// Failed to determine if it's a file.
System.err.println(x);
return false;
}
}
};
For other filtering examples, [see documentation].(http://docs.oracle.com/javase/tutorial/essential/io/dirs.html#glob)
In case anyone else has the same issue as this on
Centos, try:
yum install python-lxml
Ubuntu
sudo apt-get install -y python-lxml

UPDATE some_table SET some_field = REPLACE(some_field, '<', '<')
You can't commit empty folders in git. If you want it to show up, you need to put something in it, even just an empty file.
For example, add an empty file called .gitkeep
to the folder you want to keep, then in your .gitignore
file write:
# exclude everything
somefolder/*
# exception to the rule
!somefolder/.gitkeep
Commit your .gitignore
and .gitkeep
files and this should resolve your issue.
Here is a working example in both Javascript and jQuery:
http://jsfiddle.net/GuLYN/312/
//In jQuery
$("#calculate").click(function() {
var num = parseFloat($("#textbox").val());
var new_num = $("#textbox").val(num.toFixed(2));
});
// In javascript
document.getElementById('calculate').onclick = function() {
var num = parseFloat(document.getElementById('textbox').value);
var new_num = num.toFixed(2);
document.getElementById('textbox').value = new_num;
};
?
if you are using tomcat you may try this
<servlet-mapping>
<http-method>POST</http-method>
</servlet-mapping>
in addition to <servlet-name>
and <url-mapping>
The input operator for number skips leading whitespace, so you can just read the number in a loop:
while (myfile >> a)
{
// ...
}
As an alternative to alex's answer:
You could use a SVG drawing instead of a Canvas drawing. There you can add events directly to the drawn DOM objects.
see for example:
Making an svg image object clickable with onclick, avoiding absolute positioning
I had the same problem you had. I used a for loop with the sorted function passing in the dictionary like so:
for item in sorted(mydict):
print(item)
My study shows that finish()
method actually places some destruction operations in the queue, but the Activity is not destroyed immediately. The destruction is scheduled though.
For example, if you place finish()
in onActivityResult()
callback, while onResume()
has yet to run, then first onResume()
will be executed, and only after that onStop()
and onDestroy()
are called.
NOTE: onDestroy()
may not be called at all, as stated on the documentation.
Pure datetime solution, does not depend on language or DATEFORMAT, no strings
SELECT
DATEADD(year, [year]-1900, DATEADD(month, [month]-1, DATEADD(day, [day]-1, 0)))
FROM
dbo.Table
This is because a DATE
column in Oracle also contains a time part. The result of the to_date()
function is a date with the time set to 00:00:00
and thus it probably doesn't match any rows in the table.
You should use:
SELECT EMP_NAME, DEPT
FROM EMPLOYEE
WHERE trunc(TIME_CREATED) = TO_DATE('26/JAN/2011','dd/mon/yyyy')
In httpd.conf file you need to remove #

after removing # line will look like this:
LoadModule rewrite_module modules/mod_rewrite.so

I took Grouchal's code and to speed it up I used enumeration with concurrent mode (NSEnumerationConcurrent
), it got a bit faster compared to for loop (in my app I added this feature for Testers so that they can clear data and do testcases rather than delete and install app)
- (void)resetObjects
{
[self deleteAllObjectsInEntity:@"Entity1"];
[self deleteAllObjectsInEntity:@"Entity2"];
[self deleteAllObjectsInEntity:@"Entity3"];
[self deleteAllObjectsInEntity:@"Entity4"];
}
-(void) deleteAllObjectsInEntity:(NSString*) entityName
{
MainDataContext *coreDataContext = [MainDataContext sharedInstance];
NSManagedObjectContext *currentContext = coreDataContext.managedObjectContext;
NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init];
NSEntityDescription *entity = [NSEntityDescription entityForName:entityName inManagedObjectContext:currentContext];
[fetchRequest setEntity:entity];
NSError *error;
NSArray *items = [currentContext executeFetchRequest:fetchRequest error:&error];
[items enumerateObjectsWithOptions:NSEnumerationConcurrent usingBlock:^(NSManagedObject * obj, NSUInteger idx, BOOL *stop) {
[currentContext deleteObject:obj];
}];
if (![currentContext save:&error]) {
NSLog(@"Error deleting %@ - error:%@",entityName,error);
}
}
Try remove_missing
instead with vars = the_variable
. It is very important that you set the vars
argument, otherwise remove_missing
will remove all rows that contain an NA
in any column!! Setting na.rm = TRUE
will suppress the warning message.
ggplot(data = remove_missing(MyData, na.rm = TRUE, vars = the_variable),aes(x= the_variable, fill=the_variable, na.rm = TRUE)) +
geom_bar(stat="bin")
Why don't you just compile your VB
code into a library(.dll
).Reference it later from your code and that's it. Managed dlls
contain MSIL
to which both c#
and vb
are compiled.
There are already answers here, but here's my pure JS implementation. I'm not sure if it's optimal, but it sure is transparent, readable, and simple.
// Does array a contain elements of array b?
const contains = (a, b) => new Set([...a, ...b]).size === a.length
const isEqualSet = (a, b) => contains(a, b) && contains(b, a)
The rationale in contains()
is that if a
does contain all the elements of b
, then putting them into the same set would not change the size.
For example, if const a = [1,2,3,4]
and const b = [1,2]
, then new Set([...a, ...b]) === {1,2,3,4}
. As you can see, the resulting set has the same elements as a
.
From there, to make it more concise, we can boil it down to the following:
const isEqualSet = (a, b) => {
const unionSize = new Set([...a, ...b])
return unionSize === a.length && unionSize === b.length
}

There are a number of ways to get information on the attributes of your DataFrame or Series.
Create Sample DataFrame and Series
df = pd.DataFrame({'a':[5, 2, np.nan], 'b':[ 9, 2, 4]})
df
a b
0 5.0 9
1 2.0 2
2 NaN 4
s = df['a']
s
0 5.0
1 2.0
2 NaN
Name: a, dtype: float64
shape
AttributeThe shape
attribute returns a two-item tuple of the number of rows and the number of columns in the DataFrame. For a Series, it returns a one-item tuple.
df.shape
(3, 2)
s.shape
(3,)
len
functionTo get the number of rows of a DataFrame or get the length of a Series, use the len
function. An integer will be returned.
len(df)
3
len(s)
3
size
attributeTo get the total number of elements in the DataFrame or Series, use the size
attribute. For DataFrames, this is the product of the number of rows and the number of columns. For a Series, this will be equivalent to the len
function:
df.size
6
s.size
3
ndim
attributeThe ndim
attribute returns the number of dimensions of your DataFrame or Series. It will always be 2 for DataFrames and 1 for Series:
df.ndim
2
s.ndim
1
count
methodThe count
method can be used to return the number of non-missing values for each column/row of the DataFrame. This can be very confusing, because most people normally think of count as just the length of each row, which it is not. When called on a DataFrame, a Series is returned with the column names in the index and the number of non-missing values as the values.
df.count() # by default, get the count of each column
a 2
b 3
dtype: int64
df.count(axis='columns') # change direction to get count of each row
0 2
1 2
2 1
dtype: int64
For a Series, there is only one axis for computation and so it just returns a scalar:
s.count()
2
info
method for retrieving metadataThe info
method returns the number of non-missing values and data types of each column
df.info()
<class 'pandas.core.frame.DataFrame'>
RangeIndex: 3 entries, 0 to 2
Data columns (total 2 columns):
a 2 non-null float64

well i found a solution to this problem for who want to work with xCode 4. All what you have to do is importing frameworks from the SimulatorSDK folder /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator4.3.sdk/System/Library/Frameworks
i don't know if it works when you try to test your app on a real iDevice, but i'm sure that it works on simulator.
ENJOY
I have tried your code and it works just fine. The file is being created without any problem, this is the code I used (it's your code, I just changed the datasource for testing):
public ActionResult ExportToExcel()
{
var products = new System.Data.DataTable("teste");
products.Columns.Add("col1", typeof(int));
products.Columns.Add("col2", typeof(string));
products.Rows.Add(1, "product 1");
products.Rows.Add(2, "product 2");
products.Rows.Add(3, "product 3");
products.Rows.Add(4, "product 4");
products.Rows.Add(5, "product 5");
products.Rows.Add(6, "product 6");
products.Rows.Add(7, "product 7");
var grid = new GridView();
grid.DataSource = products;
grid.DataBind();
Response.ClearContent();
Response.Buffer = true;
Response.AddHeader("content-disposition", "attachment; filename=MyExcelFile.xls");
Response.ContentType = "application/ms-excel";
Response.Charset = "";
StringWriter sw = new StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(sw);
grid.RenderControl(htw);
Response.Output.Write(sw.ToString());
Response.Flush();
Response.End();
return View("MyView");
}
There are MANY reasons to use brace initialization, but you should be aware that the initializer_list<>
constructor is preferred to the other constructors, the exception being the default-constructor. This leads to problems with constructors and templates where the type T
constructor can be either an initializer list or a plain old ctor.
struct Foo {
Foo() {}
Foo(std::initializer_list<Foo>) {
std::cout << "initializer list" << std::endl;
}
Foo(const Foo&) {
std::cout << "copy ctor" << std::endl;
}
};
int main() {
Foo a;
Foo b(a); // copy ctor
Foo c{a}; // copy ctor (init. list element) + initializer list!!!
}
Assuming you don't encounter such classes there is little reason not to use the intializer list.
You need to set the default timezone smth like this :
date_default_timezone_set('Europe/Bucharest');
More info about this in http://php.net/manual/en/function.date-default-timezone-set.php
Or you could use @
in front of date to suppress the warning however as the warning states it's not safe to rely on the servers default timezone
You could try this:
IWebElement dropDownListBox = driver.findElement(By.Id("selection"));
SelectElement clickThis = new SelectElement(dropDownListBox);
clickThis.SelectByText("Germany");
Try the following keystrokes:
gg=G
Explanation: gg
goes to the top of the file, =
is a command to fix the indentation and G
tells it to perform the operation to the end of the file.
For me on RN 0.50.3 it's possible with this way:
<TextInput
autoFocus={true}
onSubmitEditing={() => {this.PasswordInputRef._root.focus()}}
/>
<TextInput ref={input => {this.PasswordInputRef = input}} />
You must see this.PasswordInputRef._root.focus()
In views with {{}}
and/or ng-model, Angular is setting up $watch()
es for you behind the scenes.
By default $watch
compares by reference. If you set the third parameter to $watch
to true
, Angular will instead "shallow" watch the object for changes. For arrays this means comparing the array items, for object maps this means watching the properties. So this should do what you want:
$scope.$watch('myModel', function() { ... }, true);
Update: Angular v1.2 added a new method for this, `$watchCollection():
$scope.$watchCollection('myModel', function() { ... });
Note that the word "shallow" is used to describe the comparison rather than "deep" because references are not followed -- e.g., if the watched object contains a property value that is a reference to another object, that reference is not followed to compare the other object.
You can use yourstring.split("\x09"); I tested it, and it works.
try
time="12:12:12";
tt=time.split(":");
sec=tt[0]*3600+tt[1]*60+tt[2]*1;
Runas doesn't magically run commands as an administrator, it runs them as whatever account you provide credentials for. If it's not an administrator account, runas doesn't care.
It's important to specify timeouts, especially when the server takes to respond. With pure Java, without using any dependency:
public static byte[] copyURLToByteArray(final String urlStr,
final int connectionTimeout, final int readTimeout)
throws IOException {
final URL url = new URL(urlStr);
final URLConnection connection = url.openConnection();
connection.setConnectTimeout(connectionTimeout);
connection.setReadTimeout(readTimeout);
try (InputStream input = connection.getInputStream();
ByteArrayOutputStream output = new ByteArrayOutputStream()) {
final byte[] buffer = new byte[8192];
for (int count; (count = input.read(buffer)) > 0;) {
output.write(buffer, 0, count);
}
return output.toByteArray();
}
}
Using dependencies, e.g., HC Fluent:
public byte[] copyURLToByteArray(final String urlStr,
final int connectionTimeout, final int readTimeout)
throws IOException {
return Request.Get(urlStr)
.connectTimeout(connectionTimeout)
.socketTimeout(readTimeout)
.execute()
.returnContent()
.asBytes();
}
pandas.Series.astype
You can do something like this :
weather["Temp"] = weather.Temp.astype(float)
You can also use pd.to_numeric
that will convert the column from object to float
Example :
s = pd.Series(['apple', '1.0', '2', -3])
print(pd.to_numeric(s, errors='ignore'))
print("=========================")
print(pd.to_numeric(s, errors='coerce'))
Output:
0 apple
1 1.0
2 2
3 -3
=========================
dtype: object
0 NaN
1 1.0
2 2.0
3 -3.0
dtype: float64
In your case you can do something like this:
weather["Temp"] = pd.to_numeric(weather.Temp, errors='coerce')
convert_objects
Example is as follows
>> pd.Series([1,2,3,4,'.']).convert_objects(convert_numeric=True)
0 1
1 2
2 3
3 4
4 NaN
dtype: float64
You can use this as follows:
weather["Temp"] = weather.Temp.convert_objects(convert_numeric=True)
NaN
... so be careful while using it.You must set proxy server for gradle at some time, you can try to change the proxy server ip address in gradle.properties which is under .gradle document
semeTextView.setTextSize(TypedValue.COMPLEX_UNIT_PX,
context.getResources().getDimension(R.dimen.text_size_in_dp))
Just use that:
var myDateUtc = DateTime.SpecifyKind(DateTime.Parse("Tue, 1 Jan 2008 00:00:00"), DateTimeKind.Utc);
if (myDateUtc.Kind == DateTimeKind.Utc)
{
Console.WriteLine("Yes. I am UTC!");
}
You can test this code using the online c# compiler:
I hope it helps.
I've created a small helper for a similar scenario because I often needed to override functions from several libraries. This helper accepts a "namespace" (the function container), the function name, and the overriding function. It will replace the original function in the referred namespace with the new one.
The new function accepts the original function as the first argument, and the original functions arguments as the rest. It will preserve the context everytime. It supports void and non-void functions as well.
function overrideFunction(namespace, baseFuncName, func) {
var originalFn = namespace[baseFuncName];
namespace[baseFuncName] = function () {
return func.apply(this, [originalFn.bind(this)].concat(Array.prototype.slice.call(arguments, 0)));
};
}
Usage for example with Bootstrap:
overrideFunction($.fn.popover.Constructor.prototype, 'leave', function(baseFn, obj) {
// ... do stuff before base call
baseFn(obj);
// ... do stuff after base call
});
I didn't create any performance tests though. It can possibly add some unwanted overhead which can or cannot be a big deal, depending on scenarios.
After experimenting on that case:
android:textColor="@colors/text_color"
is wrong since @color
is not filename dependant. You can name your resource file foobar.xml, it doesn't matter but if you have defined some colors in it you can access them using @color/some_color
.
Update:
file location: res/values/colors.xml The filename is arbitrary. The element's name will be used as the resource ID. (Source)
There's no easy way (in terms of performance) to do what you want to do.
Reflection works with assemblys and types mainly so you'll have to get all the types of the assembly and query them for the right interface. Here's an example:
Assembly asm = Assembly.Load("MyAssembly");
Type[] types = asm.GetTypes();
Type[] result = types.where(x => x.GetInterface("IMyInterface") != null);
That will get you all the types that implement the IMyInterface in the Assembly MyAssembly
Most of the above codes won't work with IE version. The solution that works for IE+ other browsers is this.
<style type="text/css">
tr:nth-child(2n) {
background-color: #FFEBCD;
}
</style>
A way that I have done this is as follows:
At the python shell:
>>> from cryptography.fernet import Fernet
>>> key = Fernet.generate_key()
>>> print(key)
b'B8XBLJDiroM3N2nCBuUlzPL06AmfV4XkPJ5OKsPZbC4='
>>> cipher = Fernet(key)
>>> password = "thepassword".encode('utf-8')
>>> token = cipher.encrypt(password)
>>> print(token)
b'gAAAAABe_TUP82q1zMR9SZw1LpawRLHjgNLdUOmW31RApwASzeo4qWSZ52ZBYpSrb1kUeXNFoX0tyhe7kWuudNs2Iy7vUwaY7Q=='
Then, create a module with the following code:
from cryptography.fernet import Fernet
# you store the key and the token
key = b'B8XBLJDiroM3N2nCBuUlzPL06AmfV4XkPJ5OKsPZbC4='
token = b'gAAAAABe_TUP82q1zMR9SZw1LpawRLHjgNLdUOmW31RApwASzeo4qWSZ52ZBYpSrb1kUeXNFoX0tyhe7kWuudNs2Iy7vUwaY7Q=='
# create a cipher and decrypt when you need your password
cipher = Fernet(key)
mypassword = cipher.decrypt(token).decode('utf-8')
Once you've done this, you can either import mypassword directly or you can import the token and cipher to decrypt as needed.
Obviously, there are some shortcomings to this approach. If someone has both the token and the key (as they would if they have the script), they can decrypt easily. However it does obfuscate, and if you compile the code (with something like Nuitka) at least your password won't appear as plain text in a hex editor.
you can do this easily without manual editing or using fancy text editors. Here's a vbscript.
Set objFS = CreateObject("Scripting.FileSystemObject")
strFolder="c:\test"
Set objFolder = objFS.GetFolder(strFolder)
For Each strFile In objFolder.Files
If objFS.GetExtensionName(strFile) = "jpg" Then
strFileName = strFile.Name
If InStr(strFileName,"Vacation2010") > 0 Then
strNewFileName = Replace(strFileName,"Vacation2010","December")
strFile.Name = strNewFileName
End If
End If
Next
save as myscript.vbs and
C:\test> cscript //nologo myscript.vbs
In VS 2019, just do FETCH Do not pull code.
This is what I did. Added below in .gitconfig file so that I can use Beyond Compare
File location: C:\Users\[username]\.gitconfig
Added below
[diff]
tool = bc
[difftool "bc"]
path = c:/Program Files/Beyond Compare 4/bcomp.exe
Open command prompt and go to working directory. I gave below to compare local DEV branch to remote DEV branch
git difftool dev origin/dev --dir-diff
This will open Beyond Compare and open directories which have files that differ. If no changes Beyond Compare will not launch.
There are plenty of free portable GUI libraries, each with its own strengths and weaknesses:
Especially Qt has nice tutorials and tools which help you getting started. Enjoy!
Note, however, that you should avoid platform specific functionality such as the Win32 API or MFC. That ties you unnecessarily on a specific platform with almost no benefits.
One of the way is Using below sql queries
--Size of All Table Space
--1. Used Space
SELECT TABLESPACE_NAME,TO_CHAR(SUM(NVL(BYTES,0))/1024/1024/1024, '99,999,990.99') AS "USED SPACE(IN GB)" FROM USER_SEGMENTS GROUP BY TABLESPACE_NAME
--2. Free Space
SELECT TABLESPACE_NAME,TO_CHAR(SUM(NVL(BYTES,0))/1024/1024/1024, '99,999,990.99') AS "FREE SPACE(IN GB)" FROM USER_FREE_SPACE GROUP BY TABLESPACE_NAME
--3. Both Free & Used
SELECT USED.TABLESPACE_NAME, USED.USED_BYTES AS "USED SPACE(IN GB)", FREE.FREE_BYTES AS "FREE SPACE(IN GB)"
FROM
(SELECT TABLESPACE_NAME,TO_CHAR(SUM(NVL(BYTES,0))/1024/1024/1024, '99,999,990.99') AS USED_BYTES FROM USER_SEGMENTS GROUP BY TABLESPACE_NAME) USED
INNER JOIN
(SELECT TABLESPACE_NAME,TO_CHAR(SUM(NVL(BYTES,0))/1024/1024/1024, '99,999,990.99') AS FREE_BYTES FROM USER_FREE_SPACE GROUP BY TABLESPACE_NAME) FREE
ON (USED.TABLESPACE_NAME = FREE.TABLESPACE_NAME);
Unfortunately, the accepted answer doesn't work for me (I'm using GitHub flavoured markdown).
It occurs to me since we're adding HTML elements, why not just add an <input>
instead.
| demo | demo |
| ------------------------------------------------- | ---- |
| <input type="checkbox" disabled checked /> works | |
| <input type="checkbox" disabled /> works here too | |
This should work in any environment cuz it's plain HTML (see FYI below).
FYI, this example was tested in VS Code markdown preview mode(GitHub flavoured), the screenshot is also taken in VS Code preview mode, It's not exactly working on GitHub.
Emoji mentioned above is a good alternative, if this doesn't work in your target environment.
The benefit is that the output of previous function is used. You do not need to repeat where the data source comes from, for example.
I had this problem. Solution for me was to remove links to Vue.js files. Vue.js and JQuery have some conflicts in datepicker and datetimepicker functions.
As of version 0.23, you can directly return a DataFrame using the as_frame
argument.
For example, loading the iris data set:
from sklearn.datasets import load_iris
iris = load_iris(as_frame=True)
df = iris.data
In my understanding using the provisionally release notes, this works for the breast_cancer, diabetes, digits, iris, linnerud, wine and california_houses data sets.
I encountered this issue in a NodeJS Lambda function that was triggered by a file upload to S3.
My mistake was that I was not decoding the object key, which contained a colon. Corrected my code as follows:
let key = decodeURIComponent(event.Records[0].s3.object.key);
There are updated now and then, just keep checking for the latest version.
SQL%ROWCOUNT
can also be used without being assigned (at least from Oracle 11g).
As long as no operation (updates, deletes or inserts) has been performed within the current block, SQL%ROWCOUNT
is set to null. Then it stays with the number of line affected by the last DML operation:
say we have table CLIENT
create table client (
val_cli integer
,status varchar2(10)
)
/
We would test it this way:
begin
dbms_output.put_line('Value when entering the block:'||sql%rowcount);
insert into client
select 1, 'void' from dual
union all select 4, 'void' from dual
union all select 1, 'void' from dual
union all select 6, 'void' from dual
union all select 10, 'void' from dual;
dbms_output.put_line('Number of lines affected by previous DML operation:'||sql%rowcount);
for val in 1..10
loop
update client set status = 'updated' where val_cli = val;
if sql%rowcount = 0 then
dbms_output.put_line('no client with '||val||' val_cli.');
elsif sql%rowcount = 1 then
dbms_output.put_line(sql%rowcount||' client updated for '||val);
else -- >1
dbms_output.put_line(sql%rowcount||' clients updated for '||val);
end if;
end loop;
end;
Resulting in:
Value when entering the block:
Number of lines affected by previous DML operation:5
2 clients updated for 1
no client with 2 val_cli.
no client with 3 val_cli.
1 client updated for 4
no client with 5 val_cli.
1 client updated for 6
no client with 7 val_cli.
no client with 8 val_cli.
no client with 9 val_cli.
1 client updated for 10
You're population is from the server-side. Using the registerclientscript will put the script at the beginning of the form.. you'll want to use RegisterStartupScript(Block) to have the script placed at the end of the page in question.
The former tries to run the script before the text area exists in the dom, the latter will run the script after that element in the page is created.
This solution creates a psobject and adds each object to an array, it then creates the csv by piping the contents of the array through Export-CSV.
$results = @()
foreach ($computer in $computerlist) {
if((Test-Connection -Cn $computer -BufferSize 16 -Count 1 -ea 0 -quiet))
{
foreach ($file in $REMOVE) {
Remove-Item "\\$computer\$DESTINATION\$file" -Recurse
Copy-Item E:\Code\powershell\shortcuts\* "\\$computer\$DESTINATION\"
}
} else {
$details = @{
Date = get-date
ComputerName = $Computer
Destination = $Destination
}
$results += New-Object PSObject -Property $details
}
}
$results | export-csv -Path c:\temp\so.csv -NoTypeInformation
If you pipe a string object to a csv you will get its length written to the csv, this is because these are properties of the string, See here for more information.
This is why I create a new object first.
Try the following:
write-output "test" | convertto-csv -NoTypeInformation
This will give you:
"Length"
"4"
If you use the Get-Member on Write-Output as follows:
write-output "test" | Get-Member -MemberType Property
You will see that it has one property - 'length':
TypeName: System.String
Name MemberType Definition
---- ---------- ----------
Length Property System.Int32 Length {get;}
This is why Length will be written to the csv file.
Update: Appending a CSV Not the most efficient way if the file gets large...
$csvFileName = "c:\temp\so.csv"
$results = @()
if (Test-Path $csvFileName)
{
$results += Import-Csv -Path $csvFileName
}
foreach ($computer in $computerlist) {
if((Test-Connection -Cn $computer -BufferSize 16 -Count 1 -ea 0 -quiet))
{
foreach ($file in $REMOVE) {
Remove-Item "\\$computer\$DESTINATION\$file" -Recurse
Copy-Item E:\Code\powershell\shortcuts\* "\\$computer\$DESTINATION\"
}
} else {
$details = @{
Date = get-date
ComputerName = $Computer
Destination = $Destination
}
$results += New-Object PSObject -Property $details
}
}
$results | export-csv -Path $csvFileName -NoTypeInformation
Looks like you might have until the end of 2013 before they officially close it down. http://groups.google.com/group/google-ajax-search-api/browse_thread/thread/6aaa1b3529620610/d70f8eec3684e431?lnk=gst&q=news+api#d70f8eec3684e431

Things to note, the title, author and date fields are declared before \begin{document}
. Also, the multicol package is likely unnecessary in this case since you have declared twocolumn
in the document class.
This example puts all four authors on the same line, but if your authors have longer names, departments or emails, this might cause it to flow over onto another line. You might be able to change the font sizes around a little bit to make things fit. This could be done by doing something like {\small First Author}
. Here's a more detailed article on \LaTeX
font sizes:
https://engineering.purdue.edu/ECN/Support/KB/Docs/LaTeXChangingTheFont
To italicize you can use {\it First Name}
or \textit{First Name}
.
Be careful though, if the document is meant for publication often times journals or conference proceedings have their own formatting guidelines so font size trickery might not be allowed.
You can use quotemeta (\Q \E)
if your Perl is version 5.16 or later, but if below you can simply avoid using a regular expression at all.
For example, by using the index
command:
if (index($text_to_search, $search_string) > -1) {
print "wee";
}
I have same problem!
Found following in oracle site link text
As mentioned above, the 11.1 drivers by default convert SQL DATE to Timestamp when reading from the database. This always was the right thing to do and the change in 9i was a mistake. The 11.1 drivers have reverted to the correct behavior. Even if you didn't set V8Compatible in your application you shouldn't see any difference in behavior in most cases. You may notice a difference if you use getObject to read a DATE column. The result will be a Timestamp rather than a Date. Since Timestamp is a subclass of Date this generally isn't a problem. Where you might notice a difference is if you relied on the conversion from DATE to Date to truncate the time component or if you do toString on the value. Otherwise the change should be transparent.
If for some reason your app is very sensitive to this change and you simply must have the 9i-10g behavior, there is a connection property you can set. Set mapDateToTimestamp to false and the driver will revert to the default 9i-10g behavior and map DATE to Date.
Two quick possibilities:
if(!('foo' in myObj)) { ... }
or
if(myObj['foo'] === undefined) { ... }
Since ArrayList takes to much memory when I need array of primitive types, I prefer using IntStream.builder() for creating int array (You can also use LongStream and DoubleStream builders).
Example:
Builder builder = IntStream.builder();
int arraySize = new Random().nextInt();
for(int i = 0; i<arraySize; i++ ) {
builder.add(i);
}
int[] array = builder.build().toArray();
Note: available since Java 8.
Once you have the initial ul, you can use the children() method, which will only consider the immediate children of the element. As @activa points out, one way to easily select the root element is to give it a class or an id. The following assumes you have a root ul with id root
.
$('ul#root').children('li');
The following will parse an XML string into an XML document in all major browsers, including Internet Explorer 6. Once you have that, you can use the usual DOM traversal methods/properties such as childNodes and getElementsByTagName() to get the nodes you want.
var parseXml;
if (typeof window.DOMParser != "undefined") {
parseXml = function(xmlStr) {
return ( new window.DOMParser() ).parseFromString(xmlStr, "text/xml");
};
} else if (typeof window.ActiveXObject != "undefined" &&
new window.ActiveXObject("Microsoft.XMLDOM")) {
parseXml = function(xmlStr) {
var xmlDoc = new window.ActiveXObject("Microsoft.XMLDOM");
xmlDoc.async = "false";
xmlDoc.loadXML(xmlStr);
return xmlDoc;
};
} else {
throw new Error("No XML parser found");
}
Example usage:
var xml = parseXml("<foo>Stuff</foo>");
alert(xml.documentElement.nodeName);

setting the overflow
should take care of it, but you need to set the height of Content
also. If the height attribute is not set, the div will grow vertically as tall as it needs to, and scrollbars wont be needed.

This guy wrote a custom directive to get around the issue that "true" and "false" are strings, not booleans.
Underscore-java library contains methods push(values), pop(), shift() and unshift(values).
Code example:
import com.github.underscore.U:
List<String> strings = Arrays.asList("one", "two", " three");
List<String> newStrings = U.push(strings, "four", "five");
// ["one", " two", "three", " four", "five"]
String newPopString = U.pop(strings).fst();
// " three"
String newShiftString = U.shift(strings).fst();
// "one"
List<String> newUnshiftStrings = U.unshift(strings, "four", "five");
// ["four", " five", "one", " two", "three"]
timestamp
(or date
or time
columns) do NOT have "a format".
Any formatting you see is applied by the SQL client you are using.
To insert the current time use current_timestamp
as documented in the manual:
INSERT into "Group" (name,createddate)
VALUES ('Test', current_timestamp);
To display that value in a different format change the configuration of your SQL client or format the value when SELECTing the data:
select name, to_char(createddate, ''yyyymmdd hh:mi:ss tt') as created_date
from "Group"
For psql
(the default command line client) you can configure the display format through the configuration parameter DateStyle
: https://www.postgresql.org/docs/current/static/runtime-config-client.html#GUC-DATESTYLE
var html = "<p>Hello, <b>World</b>";
var div = document.createElement("div");
div.innerHTML = html;
alert(div.innerText); // Hello, World
That pretty much the best way of doing it, you're letting the browser do what it does best -- parse HTML.
Edit: As noted in the comments below, this is not the most cross-browser solution. The most cross-browser solution would be to recursively go through all the children of the element and concatenate all text nodes that you find. However, if you're using jQuery, it already does it for you:
alert($("<p>Hello, <b>World</b></p>").text());
Check out the text method.
A grammar is context-free if all production rules have the form: A (that is, the left side of a rule can only be a single variable; the right side is unrestricted and can be any sequence of terminals and variables).
We can define a grammar as a 4-tuple where V is a finite set (variables), _ is a finite set (terminals), S is the start variable, and R is a finite set of rules, each of which is a mapping V
regular grammar is either right or left linear, whereas context free grammar is basically any combination of terminals and non-terminals. hence we can say that regular grammar is a subset of context-free grammar.
After these properties we can say that Context Free Languages set also contains Regular Languages set
You can use top or ps commands to check the CPU usage.
using top : This will show you the cpu stats
top -b -n 1 |grep ^Cpu
using ps: This will show you the % cpu usage for each process.
ps -eo pcpu,pid,user,args | sort -r -k1 | less
Also, you can write a small script in bash or perl to read /proc/stat and calculate the CPU usage.
You want to set the first character of the string to zero, like this:
char myString[10];
myString[0] = '\0';
(Or myString[0] = 0;
)
Or, actually, on initialisation, you can do:
char myString[10] = "";
But that's not a general way to set a string to zero length once it's been defined.
A pem
file contains the certificate and the private key. It depends on the format your certificate/key are in, but probably it's as simple as this:
cat server.crt server.key > server.pem
As of React Native 0.42 height:
and width:
accept percentages.
Use width: 80%
in your stylesheets and it just works.
Screenshot
Live Example
Child Width/Height as Proportion of Parent
Code
import React from 'react';
import { Text, View, StyleSheet } from 'react-native';
const width_proportion = '80%';
const height_proportion = '40%';
const styles = StyleSheet.create({
screen: {
flex: 1,
alignItems: 'center',
justifyContent: 'center',
backgroundColor: '#5A9BD4',
},
box: {
width: width_proportion,
height: height_proportion,
alignItems: 'center',
justifyContent: 'center',
backgroundColor: '#B8D2EC',
},
text: {
fontSize: 18,
},
});
export default () => (
<View style={styles.screen}>
<View style={styles.box}>
<Text style={styles.text}>
{width_proportion} of width{'\n'}
{height_proportion} of height
</Text>
</View>
</View>
);
From the jQuery API:
In addition to keeping any additional handlers on an element from being executed, this method also stops the bubbling by implicitly calling event.stopPropagation(). To simply prevent the event from bubbling to ancestor elements but allow other event handlers to execute on the same element, we can use event.stopPropagation() instead.
Use event.isImmediatePropagationStopped() to know whether this method was ever called (on that event object).
In short: event.stopPropagation()
allows other handlers on the same element to be executed, while event.stopImmediatePropagation()
prevents every event from running.
I should add: You should not be putting your dll's into \system32\ anyway! Modify your code, modify your installer... find a home for your bits that is NOT anywhere under c:\windows\
For example, your installer puts your dlls into:
\program files\<your app dir>\
or
\program files\common files\<your app name>\
(Note: The way you actually do this is to use the environment var: %ProgramFiles% or %ProgramFiles(x86)% to find where Program Files is.... you do not assume it is c:\program files\ ....)
and then sets a registry tag :
HKLM\software\<your app name>
-- dllLocation
The code that uses your dlls reads the registry, then dynamically links to the dlls in that location.
The above is the smart way to go.
You do not ever install your dlls, or third party dlls into \system32\ or \syswow64. If you have to statically load, you put your dlls in your exe dir (where they will be found). If you cannot predict the exe dir (e.g. some other exe is going to call your dll), you may have to put your dll dir into the search path (avoid this if at all poss!)
system32 and syswow64 are for Windows provided files... not for anyone elses files. The only reason folks got into the bad habit of putting stuff there is because it is always in the search path, and many apps/modules use static linking. (So, if you really get down to it, the real sin is static linking -- this is a sin in native code and managed code -- always always always dynamically link!)
On production servers I rename vendor
to vendor-<datetime>
, and during deployment will have two vendor dirs.
A HTTP cookie causes my system to choose the new vendor autoload.php
, and after testing I do a fully atomic/instant switch between them to disable the old vendor dir for all future requests, then I delete the previous dir a few days later.
This avoids any problem caused by filesystem caches I'm using in apache/php, and also allows any active PHP code to continue using the previous vendor dir.
Despite other answers recommending against it, I personally run composer install
on the server, since this is faster than rsync from my staging area (a VM on my laptop).
I use --no-dev --no-scripts --optimize-autoloader
. You should read the docs for each one to check if this is appropriate on your environment.
with pandas, it is much easier, for example.
assuming you have the following data as CSV and let's call it test.txt
/ test.csv
(you know CSV is a sort of text file )
a,b,c,d
1,2,3,4
5,6,7,8
now using pandas
import pandas as pd
df = pd.read_csv("./text.txt")
df_to_doct = df.to_dict()
for each row, it would be
df.to_dict(orient='records')
and that's it.
You could also simply tell your RestTemplate
to accept all media types:
@Bean
public RestTemplate restTemplate() {
final RestTemplate restTemplate = new RestTemplate();
List<HttpMessageConverter<?>> messageConverters = new ArrayList<>();
MappingJackson2HttpMessageConverter converter = new MappingJackson2HttpMessageConverter();
converter.setSupportedMediaTypes(Collections.singletonList(MediaType.ALL));
messageConverters.add(converter);
restTemplate.setMessageConverters(messageConverters);
return restTemplate;
}
You could try the following in your root directory:
// initialize git for your project, add the changes and perform a commit
git init
git add .
git commit -m "first commit"
// create heroku app and push to heroku
heroku create
git push heroku master
Not sure where you are in the process. You also don't need github to deploy on heroku, just git. Hope this helps!
Arrow looks promising for this:
>>> import arrow
>>> arrow.get('2014-11-13T14:53:18.694072+00:00').datetime
datetime.datetime(2014, 11, 13, 14, 53, 18, 694072, tzinfo=tzoffset(None, 0))
Arrow is a Python library that provides a sensible, intelligent way of creating, manipulating, formatting and converting dates and times. Arrow is simple, lightweight and heavily inspired by moment.js and requests.
Using ScrollView
is not very difficult. You can just add one to your layout and put whatever you want to scroll inside. ScrollView
only takes one child so if you want to put a few things inside then you should make the first thing be something like a LinearLayout
.
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<!-- things to scroll -->
</LinearLayout>
</ScrollView>
If you want to scroll things horizontally, then use a HorizontalScrollView
.
As is talked about in this post, sometimes you want the ScrollView
content to fill the screen. For example, if you had some buttons at the end of a readme. You want the buttons to always be at the end of the text and at bottom of the screen, even if the text doesn't scroll.
If the content scrolls, everything is fine. However, if the content is smaller than the size of the screen, the buttons are not at the bottom.
This can be solved with a combination of using fillViewPort
on the ScrollView
and using a layout weight on the content. Using fillViewPort
makes the ScrollView
fill the parent area. Setting the layout_weight
on one of the views in the LinearLayout
makes that view expand to fill any extra space.
Here is the XML
<?xml version="1.0" encoding="utf-8"?>
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true"> <--- fillViewport
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<TextView
android:id="@+id/textview"
android:layout_height="0dp" <---
android:layout_weight="1" <--- set layout_weight
android:layout_width="match_parent"
android:padding="6dp"
android:text="hello"/>
<LinearLayout
android:layout_height="wrap_content" <--- wrap_content
android:layout_width="match_parent"
android:background="@android:drawable/bottom_bar"
android:gravity="center_vertical">
<Button
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="wrap_content"
android:text="Accept" />
<Button
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="wrap_content"
android:text="Refuse" />
</LinearLayout>
</LinearLayout>
</ScrollView>

On Windows pip3
should be in the Scripts
path of your Python installation:
C:\path\to\python\Scripts\pip3
Use:
where python
to find out where your Python executable(s) is/are located. The result should look like this:
C:\path\to\python\python.exe
or:
C:\path\to\python\python3.exe
You can check if pip3
works with this absolute path:
C:\path\to\python\Scripts\pip3
if yes, add C:\path\to\python\Scripts
to your environmental variable PATH
.
exec 3>&1 1>>${LOG_FILE} 2>&1
would send stdout and stderr output into the log file, but would also leave you with fd 3 connected to the console, so you can do
echo "Some console message" 1>&3
to write a message just to the console, or
echo "Some console and log file message" | tee /dev/fd/3
to write a message to both the console and the log file - tee
sends its output to both its own fd 1 (which here is the LOG_FILE
) and the file you told it to write to (which here is fd 3, i.e. the console).
Example:
exec 3>&1 1>>${LOG_FILE} 2>&1
echo "This is stdout"
echo "This is stderr" 1>&2
echo "This is the console (fd 3)" 1>&3
echo "This is both the log and the console" | tee /dev/fd/3
would print
This is the console (fd 3)
This is both the log and the console
on the console and put
This is stdout
This is stderr
This is both the log and the console
into the log file.

Just to top this up to the new Java 8 API:
DateTimeFormatter formatter = new DateTimeFormatterBuilder().appendPattern("MMMM dd, yyyy").toFormatter();
TemporalAccessor ta = formatter.parse("June 27, 2007");
Instant instant = LocalDate.from(ta).atStartOfDay().atZone(ZoneId.systemDefault()).toInstant();
Date d = Date.from(instant);
assertThat(d.getYear(), is(107));
assertThat(d.getMonth(), is(5));
A bit more verbose but you also see that the methods of Date used are deprecated ;-) Time to move on.

1.if your phone system is over 4.2.2 , there will be
2.disconnect the USB and try again or restart your phone
3.After after all try , it didn't work. It may be a shortage power supply so try other usb interface on your computer.
I solved the problem doing the first step . anyway have try.

hope this helps :)
Try with the keyup event:
$(document).keyup(function(e) {
if (e.keyCode === 13) $('.save').click(); // enter
if (e.keyCode === 27) $('.cancel').click(); // esc
});
There are no problems here this is perfectly normal - it shows informational messages about what debug-info was loaded (and which wasn't) and also that your program executed and exited normally - a zero return code means success.
If you don't see anything on the screen thry running your program with CTRL-F5 instead of just F5.
Use : '
to open and '
to close.
For example:
: '
This is a

Here's my two solutions for this
1. Store in json files
Just make a json file and get in your component by $http.get()
method. If I was need this very low then it's good and quick.
2. Store by using data services
If you want to store and use in all components or having large usage then it's better to use data service. Like this :
Just create static folder inside src/app
folder.
Create a file named as fuels.ts
into static folder. You can store other static files here also. Let define your data like this. Assuming you having fuels data.
__
export const Fuels {
Fuel: [
{ "id": 1, "type": "A" },
{ "id": 2, "type": "B" },
{ "id": 3, "type": "C" },
{ "id": 4, "type": "D" },
];
}
__
import { Injectable } from "@angular/core";
import { Fuels } from "./static/fuels";
@Injectable()
export class StaticService {
constructor() { }
getFuelData(): Fuels[] {
return Fuels;
}
}`
just import in app.module.ts file like this and change in providers
import { StaticService } from './static.services';
providers: [StaticService]
Now use this as StaticService
in any module.
That's All.
I just removed all the private libraries in JavaBuildPath and added the jars again.. It worked
You can use the AssemblyName
class to get the assembly name, provided you have the full name for the assembly:
AssemblyName.GetAssemblyName(Assembly.GetExecutingAssembly().FullName).Name
or
AssemblyName.GetAssemblyName(e.Source).Name
An approach that worked for me on IE (I couldn't use the display technique because there was an input that must not loose focus)
It works if you have 0 margin (changing the padding works as well)
if(div.style.marginLeft == '0px'){
div.style.marginLeft = '';
div.style.marginRight = '0px';
} else {
div.style.marginLeft = '0px';
div.style.marginRight = '';
}
Rather humorously, considering your tags, just use the ImageButton
widget.
I think it is not totally unrelated but did you consider canvas? something like Process JS can make it simpler.
When you use routerLink like this, then you need to pass the value of the route it should go to. But when you use routerLink with the property binding syntax, like this: [routerLink]
, then it should be assigned a name of the property the value of which will be the route it should navigate the user to.
So to fix your issue, replace this routerLink="['/about']"
with routerLink="/about"
in your HTML.
There were other places where you used property binding syntax when it wasn't really required. I've fixed it and you can simply use the template syntax below:
<nav class="main-nav>
<ul
class="main-nav__list"
ng-sticky
addClass="main-sticky-link"
[ngClass]="ref.click ? 'Navbar__ToggleShow' : ''">
<li class="main-nav__item" routerLinkActive="active">
<a class="main-nav__link" routerLink="/">Home</a>
</li>
<li class="main-nav__item" routerLinkActive="active">
<a class="main-nav__link" routerLink="/about">About us</a>
</li>
</ul>
</nav>
It also needs to know where exactly should it load the template for the Component corresponding to the route it has reached. So for that, don't forget to add a <router-outlet></router-outlet>
, either in your template provided above or in a parent component.
There's another issue with your AppRoutingModule
. You need to export the RouterModule
from there so that it is available to your AppModule
when it imports it. To fix that, export it from your AppRoutingModule
by adding it to the exports
array.
import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { RouterModule, Routes } from '@angular/router';
import { MainLayoutComponent } from './layout/main-layout/main-layout.component';
import { AboutComponent } from './components/about/about.component';
import { WhatwedoComponent } from './components/whatwedo/whatwedo.component';
import { FooterComponent } from './components/footer/footer.component';
import { ProjectsComponent } from './components/projects/projects.component';
const routes: Routes = [
{ path: 'about', component: AboutComponent },
{ path: 'what', component: WhatwedoComponent },
{ path: 'contacts', component: FooterComponent },
{ path: 'projects', component: ProjectsComponent},
];
@NgModule({
imports: [
CommonModule,
RouterModule.forRoot(routes),
],
exports: [RouterModule],
declarations: []
})
export class AppRoutingModule { }
change Date to Object which is between parenthesis
Based on your question, I believe the answer is how to trigger a blur, not just (or even) set the event:
$('#textArea').trigger('blur');
Use titleLabel
instead. The font
property is deprecated in iOS 3.0. It also does not work in Objective-C. titleLabel
is label used for showing title on UIButton
.
myButton.titleLabel?.font = UIFont(name: YourfontName, size: 20)
However, while setting title text you should only use setTitle:forControlState:
. Do not use titleLabel
to set any text for title directly.
Apache Commons Collections to the rescue once again:
List<String> listA = Arrays.asList("a", "b", "b", "c");
List<String> listB = Arrays.asList("b", "c", "a", "b");
System.out.println(CollectionUtils.isEqualCollection(listA, listB)); // true
List<String> listC = Arrays.asList("a", "b", "c");
List<String> listD = Arrays.asList("a", "b", "c", "c");
System.out.println(CollectionUtils.isEqualCollection(listC, listD)); // false
org.apache.commons.collections4.CollectionUtils
public static boolean isEqualCollection(java.util.Collection a, java.util.Collection b)
Returns
true
iff the givenCollection
s contain exactly the same elements with exactly the same cardinalities.That is, iff the cardinality of e in a is equal to the cardinality of e in b, for each element e in a or b.
Parameters:
a
- the first collection, must not benull
b
- the second collection, must not benull
Returns:
true
iff the collections contain the same elements with the same cardinalities.
There is an other way to load jQuery dynamically (source). You could also use
document.write('<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"><\/script>');
It's considered bad practice to use document.write
, but for sake of completion it's good to mention it.
See Why is document.write considered a "bad practice"? for the reasons. The pro is that document.write
does block your page from loading other assests, so there is no need to create a callback function.
Well, your solution almost works. There are a few things to take into account to keep it simple:
Cancel the default navigation only for specific URLs you know a download will occur, or the user won't be able to navigate anywhere. This means you musn't change your website download URLs.
DownloadFileAsync
doesn't know the name reported by the server in the Content-Disposition
header so you have to specify one, or compute one from the original URL if that's possible. You cannot just specify the folder and expect the file name to be retrieved automatically.
You have to handle download server errors from the DownloadCompleted
callback because the web browser control won't do it for you anymore.
Sample piece of code, that will download into the directory specified in textBox1
, but with a random file name, and without any additional error handling:
private void webBrowser1_Navigating(object sender, WebBrowserNavigatingEventArgs e) {
/* change this to match your URL. For example, if the URL always is something like "getfile.php?file=xxx", try e.Url.ToString().Contains("getfile.php?") */
if (e.Url.ToString().EndsWith(".zip")) {
e.Cancel = true;
string filePath = Path.Combine(textBox1.Text, Path.GetRandomFileName());
var client = new WebClient();
client.DownloadFileCompleted += client_DownloadFileCompleted;
client.DownloadFileAsync(e.Url, filePath);
}
}
private void client_DownloadFileCompleted(object sender, AsyncCompletedEventArgs e) {
MessageBox.Show("File downloaded");
}
This solution should work but can be broken very easily. Try to consider some web service listing the available files for download and make a custom UI for it. It'll be simpler and you will control the whole process.
