You can use JavaScript to do what you want:
if (document.addEventListener !== undefined) {
// Not IE
document.addEventListener('click', checkSelection, false);
} else {
// IE
document.attachEvent('onclick', checkSelection);
}
function checkSelection() {
var sel = {};
if (window.getSelection) {
// Mozilla
sel = window.getSelection();
} else if (document.selection) {
// IE
sel = document.selection.createRange();
}
// Mozilla
if (sel.rangeCount) {
sel.removeAllRanges();
return;
}
// IE
if (sel.text > '') {
document.selection.empty();
return;
}
}
Soap box: You really shouldn't be screwing with the client's user agent in this manner. If the client wants to select things on the document, then they should be able to select things on the document. It doesn't matter if you don't like the highlight color, because you aren't the one viewing the document.
I my case I'd manually moved a .war file to /var/lib/tomcat9/webapps and unzipped it, then did "chown -R tomcat:tomcat *" in that directory and it resolved it.
names=[line.strip() for line in open('names.txt')]
I always add a target="_blank" to the download link. This will open a new window, but as soon as the user clicks save, the new window is closed.
I use this script on sql server 2008 R2.

To handle undefined variables as well as nulls, you can use substitute
with deparse
:
nullSafe <- function(x) {
if (!exists(deparse(substitute(x))) || is.null(x)) {
return(NA)
} else {
return(x)
}
}
nullSafe(my.nonexistent.var)
Having javascript:
in any attribute that isn't specifically for scripting is an outdated method of HTML. While technically it works, you're still assigning javascript properties to a non-script attribute, which isn't good practice. It can even fail on old browsers, or even some modern ones (a googled forum post seemd to indicate that Opera does not like 'javascript:' urls).
A better practice would be the second way, to put your javascript into the onclick
attribute, which is ignored if no scripting functionality is available. Place a valid URL in the href field (commonly '#') for fallback for those who do not have javascript.
Here's a snippet for generating a list of random numbers
import 'dart:math';
main() {
var rng = new Random();
var l = new List.generate(12, (_) => rng.nextInt(100));
}
This will generate a list of 12 integers from 0 to 99 (inclusive).
Another way:
# Gets the real path of a link, following all links
myreadlink() { [ ! -h "$1" ] && echo "$1" || (local link="$(expr "$(command ls -ld -- "$1")" : '.*-> \(.*\)$')"; cd $(dirname $1); myreadlink "$link" | sed "s|^\([^/].*\)\$|$(dirname $1)/\1|"); }
# Returns the absolute path to a command, maybe in $PATH (which) or not. If not found, returns the same
whereis() { echo $1 | sed "s|^\([^/].*/.*\)|$(pwd)/\1|;s|^\([^/]*\)$|$(which -- $1)|;s|^$|$1|"; }
# Returns the realpath of a called command.
whereis_realpath() { local SCRIPT_PATH=$(whereis $1); myreadlink ${SCRIPT_PATH} | sed "s|^\([^/].*\)\$|$(dirname ${SCRIPT_PATH})/\1|"; }
Better
if ! wget -q --spider --tries=10 --timeout=20 google.com
then
echo 'Sorry you are Offline'
exit 1

You can use java.net.HttpUrlConnection.
Example (from here), with improvements. Included in case of link rot:
public static String executePost(String targetURL, String urlParameters) {
HttpURLConnection connection = null;
try {
//Create connection
URL url = new URL(targetURL);
connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("POST");
connection.setRequestProperty("Content-Type",
"application/x-www-form-urlencoded");
connection.setRequestProperty("Content-Length",
Integer.toString(urlParameters.getBytes().length));
connection.setRequestProperty("Content-Language", "en-US");
connection.setUseCaches(false);
connection.setDoOutput(true);
//Send request
DataOutputStream wr = new DataOutputStream (
connection.getOutputStream());
wr.writeBytes(urlParameters);
wr.close();
//Get Response
InputStream is = connection.getInputStream();
BufferedReader rd = new BufferedReader(new InputStreamReader(is));
StringBuilder response = new StringBuilder(); // or StringBuffer if Java version 5+
String line;
while ((line = rd.readLine()) != null) {
response.append(line);
response.append('\r');
}
rd.close();
return response.toString();
} catch (Exception e) {
e.printStackTrace();
return null;
} finally {
if (connection != null) {
connection.disconnect();
}
}
}
Do I need to setup specific URLconf patters for uploaded media?
Yes. For development, it's as easy as adding this to your URLconf:
if settings.DEBUG:
urlpatterns += patterns('django.views.static',
(r'media/(?P<path>.*)', 'serve', {'document_root': settings.MEDIA_ROOT}),
)
However, for production, you'll want to serve the media using Apache, lighttpd, nginx, or your preferred web server.
For the listed three conditions only, these expressions might work also:
^\d{5}[-\s]?(?:\d{4})?$
^\[0-9]{5}[-\s]?(?:[0-9]{4})?$
^\[0-9]{5}[-\s]?(?:\d{4})?$
^\d{5}[-\s]?(?:[0-9]{4})?$
If we would have had unexpected additional spaces in between 5 and 4 digits or a continuous 9 digits zip code, such as:
123451234
12345 1234
12345 1234
this expression for instance would be a secondary option with less constraints:
^\d{5}([-]|\s*)?(\d{4})?$
jex.im visualizes regular expressions:
const regex = /^\d{5}[-\s]?(?:\d{4})?$/gm;_x000D_

You can use array_agg
function for that:
SELECT "Movie",
array_to_string(array_agg(distinct "Actor"),',') AS Actor
FROM Table1
GROUP BY "Movie";
Result:
MOVIE | ACTOR |
---|---|
A | 1,2,3 |
B | 4 |

There's a RemoveDuplicates
method that you could use:
Sub DeleteRows()
With ActiveSheet
Set Rng = Range("A1", Range("B1").End(xlDown))
Rng.RemoveDuplicates Columns:=Array(1, 2), Header:=xlYes
End With
End Sub
Really human comprehensible example (as this is the first time I am using %in%), how to compare two data frames and keep only rows containing the equal values in specific column:
# Set seed for reproducibility.
set.seed(1)
# Create two sample data frames.
data_A <- data.frame(id=c(1,2,3), value=c(1,2,3))
data_B <- data.frame(id=c(1,2,3,4), value=c(5,6,7,8))
# compare data frames by specific columns and keep only
# the rows with equal values
data_A[data_A$id %in% data_B$id,] # will keep data in data_A
data_B[data_B$id %in% data_A$id,] # will keep data in data_b
Results:
> data_A[data_A$id %in% data_B$id,]
id value
1 1 1
2 2 2
3 3 3
> data_B[data_B$id %in% data_A$id,]
id value
1 1 5
2 2 6
3 3 7
You need to tell the run to wait until the process is finished. Something like:
const DontWaitUntilFinished = false, ShowWindow = 1, DontShowWindow = 0, WaitUntilFinished = true
set oShell = WScript.CreateObject("WScript.Shell")
command = "cmd /c C:\windows\system32\wscript.exe <path>\myScript.vbs " & args
oShell.Run command, DontShowWindow, WaitUntilFinished
In the script itself, start Excel like so. While debugging start visible:
File = "c:\test\myfile.xls"
oShell.run """C:\Program Files\Microsoft Office\Office14\EXCEL.EXE"" " & File, 1, true
Retype:
$ git config credential.helper store
And then you will be prompted to enter your credentials again.

javax.servlet.Filter
.doFilter()
method, cast the incoming ServletRequest
to HttpServletRequest
.HttpServletRequest#getRequestURI()
to grab the path.java.lang.String
methods like substring()
, split()
, concat()
and so on to extract the part of interest and compose the new path.ServletRequest#getRequestDispatcher()
and then RequestDispatcher#forward()
to forward the request/response to the new URL (server-side redirect, not reflected in browser address bar), or cast the incoming ServletResponse
to HttpServletResponse
and then HttpServletResponse#sendRedirect()
to redirect the response to the new URL (client side redirect, reflected in browser address bar).web.xml
on an url-pattern
of /*
or /Check_License/*
, depending on the context path, or if you're on Servlet 3.0 already, use the @WebFilter
annotation for that instead.Don't forget to add a check in the code if the URL needs to be changed and if not, then just call FilterChain#doFilter()
, else it will call itself in an infinite loop.
Alternatively you can also just use an existing 3rd party API to do all the work for you, such as Tuckey's UrlRewriteFilter which can be configured the way as you would do with Apache's mod_rewrite
.
As of PowerShell 5.1 there cmdlet New-LocalUser
which could create local user account.
Example of usage:
Create a user account
New-LocalUser -Name "User02" -Description "Description of this account." -NoPassword
or Create a user account that has a password
$Password = Read-Host -AsSecureString
New-LocalUser "User03" -Password $Password -FullName "Third User" -Description "Description of this account."
or Create a user account that is connected to a Microsoft account
New-LocalUser -Name "MicrosoftAccount\usr [email protected]" -Description "Description of this account."
JChronic is your best choice. Here's an example that adds a .fromString()
method to the Date class that parses just about anything you can throw at it:
Date.metaClass.'static'.fromString = { str ->
com.mdimension.jchronic.Chronic.parse(str).beginCalendar.time
}
You can call it like this:
println Date.fromString("Tue Aug 10 16:02:43 PST 2010")
println Date.fromString("july 1, 2012")
println Date.fromString("next tuesday")
I had this exact error code and after checking my repository discovered that there were no go files but actually just more directories. So it was more of a red herring than an error for me.
I would recommend doing
go env
and making sure that everything is as it should be, check your environment variables in your OS and check to make sure your shell (bash or w/e ) isn't compromising it via something like a .bash_profile or .bashrc file. good luck.
For those of us who did not see -1 by Michal Chaniewski, the complete line of code:

echo "\u{00ed}";
outputs í

Scenario
In a college there are many students doing different courses, and after an examination we have to prepare a marks card showing grade. I can calculate grade two ways
1. I can write some code like this
if(totalMark <= 100 && totalMark > 90) { grade = "A+"; }
else if(totalMark <= 90 && totalMark > 80) { grade = "A"; }
else if(totalMark <= 80 && totalMark > 70) { grade = "B"; }
else if(totalMark <= 70 && totalMark > 60) { grade = "C"; }
2. You can ask user to enter grade definition some where and save that data
Something like storing into a database table
In the first case the grade is common for all the courses and if the rule changes the code needs to be changed. But for second case we are giving user the provision to enter grade based on their requirement. So the code will be not be changed when the grade rules changes.
That's the important thing when you give more provision for users to define business logic. The first case is nothing but Hard Coding.
So in your question if you ask the user to enter the path of the file at the start, then you can remove the hard coded path in your code.
You could also use Regular Expressions:
SELECT * FROM TABLE WHERE REGEXP_LIKE (TABLE.NAME,'IgNoReCaSe','i');
First of all, write the following code:
#include <Mmsystem.h>
#include <mciapi.h>
//these two headers are already included in the <Windows.h> header
#pragma comment(lib, "Winmm.lib")
To open *.mp3:
mciSendString("open \"*.mp3\" type mpegvideo alias mp3", NULL, 0, NULL);
To play *.mp3:
mciSendString("play mp3", NULL, 0, NULL);
To play and wait until the *.mp3 has finished playing:
mciSendString("play mp3 wait", NULL, 0, NULL);
To replay (play again from start) the *.mp3:
mciSendString("play mp3 from 0", NULL, 0, NULL);
To replay and wait until the *.mp3 has finished playing:
mciSendString("play mp3 from 0 wait", NULL, 0, NULL);
To play the *.mp3 and replay it every time it ends like a loop:
mciSendString("play mp3 repeat", NULL, 0, NULL);
If you want to do something when the *.mp3 has finished playing, then you need to RegisterClassEx
by the WNDCLASSEX
structure, CreateWindowEx
and process it's messages with the GetMessage, TranslateMessage and DispatchMessage functions in a while
loop and call:
mciSendString("play mp3 notify", NULL, 0, hwnd); //hwnd is an handle to the window returned from CreateWindowEx. If this doesn't work, then replace the hwnd with MAKELONG(hwnd, 0).
In the window procedure, add the case MM_MCINOTIFY:
The code in there will be executed when the mp3 has finished playing.
But if you program a Console Application and you don't deal with windows, then you can CreateThread
in suspend state by specifying the CREATE_SUSPENDED
flag in the dwCreationFlags
parameter and keep the return value in a static
variable and call it whatever you want. For instance, I call it mp3. The type of this static
variable is HANDLE
of course.
Here is the ThreadProc
for the lpStartAddress
of this thread:
DWORD WINAPI MP3Proc(_In_ LPVOID lpParameter) //lpParameter can be a pointer to a structure that store data that you cannot access outside of this function. You can prepare this structure before `CreateThread` and give it's address in the `lpParameter`
{
Data *data = (Data*)lpParameter; //If you call this structure Data, but you can call it whatever you want.
while (true)
{
mciSendString("play mp3 from 0 wait", NULL, 0, NULL);
//Do here what you want to do when the mp3 playback is over
SuspendThread(GetCurrentThread()); //or the handle of this thread that you keep in a static variable instead
}
}
All what you have to do now is to ResumeThread(mp3);
every time you want to replay your mp3 and something will happen every time it finishes.
You can #define play_my_mp3 ResumeThread(mp3);
to make your code more readable.
Of course you can remove the while (true)
, SuspendThread
and the from 0 codes, if you want to play your mp3 file only once and do whatever you want when it is over.
If you only remove the SuspendThread
call, then the sound will play over and over again and do something whenever it is over. This is equivalent to:
mciSendString("play mp3 repeat notify", NULL, 0, hwnd); //or MAKELONG(hwnd, 0) instead
in windows.
To pause the *.mp3 in middle:
mciSendString("pause mp3", NULL, 0, NULL);
and to resume it:
mciSendString("resume mp3", NULL, 0, NULL);
To stop it in middle:
mciSendString("stop mp3", NULL, 0, NULL);
Note that you cannot resume a sound that has been stopped, but only paused, but you can replay it by carrying out the play command. When you're done playing this *.mp3, don't forget to:
mciSendString("close mp3", NULL, 0, NULL);
All these actions also apply to (work with) wave files too, but with wave files, you can use "waveaudio" instead of "mpegvideo". Also you can just play them directly without opening them:
PlaySound("*.wav", GetModuleHandle(NULL), SND_FILENAME);
If you don't want to specify an handle to a module:
sndPlaySound("*.wav", SND_FILENAME);
If you don't want to wait until the playback is over:
PlaySound("*.wav", GetModuleHandle(NULL), SND_FILENAME | SND_ASYNC);
//or
sndPlaySound("*.wav", SND_FILENAME | SND_ASYNC);
To play the wave file over and over again:
PlaySound("*.wav", GetModuleHandle(NULL), SND_FILENAME | SND_ASYNC | SND_LOOP);
//or
sndPlaySound("*.wav", SND_FILENAME | SND_ASYNC | SND_LOOP);
Note that you must specify both the SND_ASYNC
and SND_LOOP
flags, because you never going to wait until a sound, that repeats itself countless times, is over!
Also you can fopen
the wave file and copy all it's bytes to a buffer (an enormous/huge (very big) array of bytes) with the fread
function and then:
PlaySound(buffer, GetModuleHandle(NULL), SND_MEMORY);
//or
PlaySound(buffer, GetModuleHandle(NULL), SND_MEMORY | SND_ASYNC);
//or
PlaySound(buffer, GetModuleHandle(NULL), SND_MEMORY | SND_ASYNC | SND_LOOP);
//or
sndPlaySound(buffer, SND_MEMORY);
//or
sndPlaySound(buffer, SND_MEMORY | SND_ASYNC);
//or
sndPlaySound(buffer, SND_MEMORY | SND_ASYNC | SND_LOOP);
Either OpenFile
or CreateFile
or CreateFile2
and either ReadFile
or ReadFileEx
functions can be used instead of fopen
and fread
functions.
Hope this fully answers perfectly your question.
best put brackets around foo, and use +=
list+=['foo']
try this way .eregi("[^A-Za-z0-9.]", $value)
Can we also use
select e2.max(sal), e2.name
from emp e2
where (e2.sal <(Select max (Salary) from empo el))
group by e2.name
Please let me know what is wrong with this approach
Update (using renderer):
Note that the original Renderer service has now been deprecated in favor of Renderer2
as on Renderer2 official doc.
Furthermore, as pointed out by @GünterZöchbauer:
Actually using ElementRef is just fine. Also using ElementRef.nativeElement with Renderer2 is fine. What is discouraged is accessing properties of ElementRef.nativeElement.xxx directly.
You can achieve this by using elementRef
as well as by ViewChild
. however it's not recommendable to use elementRef
due to:
as pointed out by official ng2 documentation.
elementRef
(Direct Access):export class MyComponent {
constructor (private _elementRef : ElementRef) {
this._elementRef.nativeElement.querySelector('textarea').focus();
}
}
ViewChild
(better approach):<textarea #tasknote name="tasknote" [(ngModel)]="taskNote" placeholder="{{ notePlaceholder }}"
style="background-color: pink" (blur)="updateNote() ; noteEditMode = false " (click)="noteEditMode = false"> {{ todo.note }} </textarea> // <-- changes id to local var
export class MyComponent implements AfterViewInit {
@ViewChild('tasknote') input: ElementRef;
ngAfterViewInit() {
this.input.nativeElement.focus();
}
}
renderer
:export class MyComponent implements AfterViewInit {
@ViewChild('tasknote') input: ElementRef;
constructor(private renderer: Renderer2){
}
ngAfterViewInit() {
//using selectRootElement instead of depreaced invokeElementMethod
this.renderer.selectRootElement(this.input["nativeElement"]).focus();
}
}
Variadic Functions can be dangerous. Here's a safer trick:
void func(type* values) {
while(*values) {
x = *values++;
/* do whatever with x */
}
}
func((type[]){val1,val2,val3,val4,0});

Should you want to clear the array with something other than a value, std::file wont cut it; instead I found std::generate useful. e.g. I had a vector of lists I wanted to initialize
std::generate(v.begin(), v.end(), [] () { return std::list<X>(); });
You can do ints too e.g.
std::generate(v.begin(), v.end(), [n = 0] () mutable { return n++; });
or just
std::generate(v.begin(), v.end(), [] (){ return 0; });
but I imagine std::fill is faster for the simplest case

Express with Tools (with LocalDB) Includes the database engine and SQL Server Management Studio Express)
This package contains everything needed to install and configure SQL Server as a database server. Choose either LocalDB or Express depending on your needs above.
That's the SQLEXPRWT_x64_ENU.exe
download.... (WT = with tools)
Express with Advanced Services (contains the database engine, Express Tools, Reporting Services, and Full Text Search)
This package contains all the components of SQL Express. This is a larger download than “with Tools,” as it also includes both Full Text Search and Reporting Services.
That's the SQLEXPRADV_x64_ENU.exe

Count character occurrences in a string is easy:
#include <bits/stdc++.h>
using namespace std;
int main()
{
string s="Sakib Hossain";
int cou=count(s.begin(),s.end(),'a');
cout<<cou;
}
I've successfully done this for my website.
Only exception is, the SeaMonkey browser requires HTML code inserted in your <head>
; whereas, the other browsers will still display the favicon.ico without any HTML insertion. Also, any browser other than IE may use other types of images, not just the .ico format. I hope this helps.
You can always use something like
"string".sub!(/.{X}$/,'')
Where X
is the number of characters to remove.
Or with assigning/using the result:
myvar = "string"[0..-X]
where X
is the number of characters plus one to remove.
Please try out this one.
d =[{'value': 'apple', 'blah': 2}, {'value': 'banana', 'blah': 3} , {'value':
'cars', 'blah': 4}]
b=d[0]['value']
c=d[1]['value']
d=d[2]['value']
new_list=[b,c,d]
print(new_list)
Output:
['apple', 'banana', 'cars']
Normaly you can GET and POST parameters in a servlet the same way:
request.getParameter("cmd");
But only if the POST data is encoded as key-value pairs of content type: "application/x-www-form-urlencoded" like when you use a standard HTML form.
If you use a different encoding schema for your post data, as in your case when you post a json data stream, you need to use a custom decoder that can process the raw datastream from:
BufferedReader reader = request.getReader();
Json post processing example (uses org.json package )
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
StringBuffer jb = new StringBuffer();
String line = null;
try {
BufferedReader reader = request.getReader();
while ((line = reader.readLine()) != null)
jb.append(line);
} catch (Exception e) { /*report an error*/ }
try {
JSONObject jsonObject = HTTP.toJSONObject(jb.toString());
} catch (JSONException e) {
// crash and burn
throw new IOException("Error parsing JSON request string");
}
// Work with the data using methods like...
// int someInt = jsonObject.getInt("intParamName");
// String someString = jsonObject.getString("stringParamName");
// JSONObject nestedObj = jsonObject.getJSONObject("nestedObjName");
// JSONArray arr = jsonObject.getJSONArray("arrayParamName");
// etc...
}
If you want to get the full path of the directory of the current rb file:
File.expand_path('../', __FILE__)
If you just want to get the information of current directory, you can type:
pwd
and you don't need to use the Nautilus, or you can use a teamviewer software to remote connect to the computer, you can get everything you want.
Calendar.getInstance().get(Calendar.DAY_OF_WEEK)
or
new GregorianCalendar().get(Calendar.DAY_OF_WEEK);
Just the same as in Java, nothing particular to Android.
You are providing a string representation of a dict to the DataFrame constructor, and not a dict itself. So this is the reason you get that error.
So if you want to use your code, you could do:
df = DataFrame(eval(data))
But better would be to not create the string in the first place, but directly putting it in a dict. Something roughly like:
data = []
for row in result_set:
data.append({'value': row["tag_expression"], 'key': row["tag_name"]})
But probably even this is not needed, as depending on what is exactly in your result_set
you could probably:
DataFrame(result_set)
read_sql_query
function to do this for you (see docs on this)This is what worked for me for IE 11+, Firefox and Chrome. In safari it downloads a file but as unknown and the filename is not set.

I fixed this problem by following the solution to this other StackOverflow question
I had the same problem. I fixed it by adding the maven archetype catalog to eclipse. Steps are provided below: (Please note the https protocol)
- Open Window > Preferences
- Open Maven > Archetypes
- Click 'Add Remote Catalog' and add the following:
- Catalog File: https://repo1.maven.org/maven2/archetype-catalog.xml
- Description: maven catalog
You can add extra data with form data
use serializeArray and add the additional data:
var data = $('#myForm').serializeArray();
data.push({name: 'tienn2t', value: 'love'});
$.ajax({
type: "POST",
url: "your url.php",
data: data,
dataType: "json",
success: function(data) {
//var obj = jQuery.parseJSON(data); if the dataType is not specified as json uncomment this
// do what ever you want with the server response
},
error: function() {
alert('error handing here');
}
});
As @jem suggested, it is possible to use jsoup.
With jSoup 1.8.3 it il possible to use the method Parser.unescapeEntities that retain the original html.
import org.jsoup.parser.Parser;
...
String html = Parser.unescapeEntities(original_html, false);
It seems that in some previous release this method is not present.
string[] filePaths = Directory.GetFiles(@"c:\MyDir\");
foreach (string filePath in filePaths)
File.Delete(filePath);
Or in a single line:
Array.ForEach(Directory.GetFiles(@"c:\MyDir\"), File.Delete);
I didn't need to install any package. Just a simple change in your WebAPI project's web.config is working great:
<system.webServer>
<httpProtocol>
<customHeaders>
<add name="Access-Control-Allow-Origin" value="*" />
</customHeaders>
</httpProtocol>
</system.webServer>

Open a PL/SQL object in the Editor.
Click on the main toolbar or select Session | Toggle Compiling with Debug. This enables debugging.
Compile the object on the database.
Select one of the following options on the Execute toolbar to begin debugging: Execute PL/SQL with debugger () Step over Step into Run to cursor
Another solution:
for /f "tokens=2 delims==" %%I in ('wmic os get localdatetime /format:list') do set datetime=%%I
It will give you (independent of locale settings!):
20130802203023.304000+120
( YYYYMMDDhhmmss.<milliseconds><always 000>+/-<minutes difference to UTC> )
From here, it is easy:
set datetime=%datetime:~0,8%-%datetime:~8,6%
20130802-203023
For Logan's request for the same outputformat for the "date-time modified" of a file:
for %%F in (test.txt) do set file=%%~fF
for /f "tokens=2 delims==" %%I in ('wmic datafile where name^="%file:\=\\%" get lastmodified /format:list') do set datetime=%%I
echo %datetime%
It is a bit more complicated, because it works only with full paths, wmic
expects the backslashes to be doubled and the =
has to be escaped (the first one. The second one is protected by surrounding quotes).
Add dependencies.
for example:- import 'package:audioplayers/audio_cache.dart';
in the above package if we only use this package then it shows error
but if we add dependencies in pubspec.yaml
such as
dependencies:
flutter:
sdk: flutter
cupertino_icons: ^0.1.2
audioplayers: ^0.14.1
then click on packages get.
as you see this, I can also insert dependencies so if you insert dependencies along with your package then you are good to go.
The solution only solves part of the problem, it may let you style the container and contents but doesn't let you change the titlebar. I developed a workaround of sorts but adding an id to the dialog div, then using jQuery .prev to change the style of the div which is the previous sibling of the dialog's div. This works because when jQueryUI creates the dialog, your original div becomes a sibling of the new container, but the title div is a the immediately previous sibling to your original div but neither the container not the title div has an id to simplify selecting the div.
HTML
<button id="dialog1" class="btn btn-danger">Warning</button>
<div title="Nothing here, really" id="nonmodal1">
Nothing here
</div>
You can use CSS to style the main section of the dialog but not the title
.custom-ui-widget-header-warning {
background: #EBCCCC;
font-size: 1em;
}
You need some JS to style the title
$(function() {
$("#nonmodal1").dialog({
minWidth: 400,
minHeight: 'auto',
autoOpen: false,
dialogClass: 'custom-ui-widget-header-warning',
position: {
my: 'center',
at: 'left'
}
});
$("#dialog1").click(function() {
if ($("#nonmodal1").dialog("isOpen") === true) {
$("#nonmodal1").dialog("close");
} else {
$("#nonmodal1").dialog("open").prev().css('background','#D9534F');
}
});
});
The example only shows simple styling (background) but you can make it as complex as you wish.
You can see it in action here:
Answer is simple. when u pass value from dropdown.
Just use as if else.
for eg:
foreach($result as $row) {
$GLOBALS['output'] .='<option value="'.$row["dropdownid"].'"'.
($GLOBALS['passselectedvalueid']==$row["dropwdownid"] ? ' Selected' : '').'
>'.$row['valueetc'].'</option>';
}
Consider a scenario where Test1, Test2 and Test3 are three classes. The Test3 class inherits Test2 and Test1 classes. If Test1 and Test2 classes have same method and you call it from child class object, there will be ambiguity to call method of Test1 or Test2 class but there is no such ambiguity for interface as in interface no implementation is there.
generally . doesn't match newlines, so try ((.|\n)*)<foobar>

Not exactly php, but you could exec a program from php to convert the pdf to a temporary html file and then parse the resulting file with php. I've done something similar for a project of mine and this is the program I used:
The resulting HTML wraps text elements in < div > tags with absolute position coordinates. It seems like this is exactly what you are trying to do.
Using the bitstring module:
>>> bitstring.BitArray(uint=1245427, length=24).bytes
'\x13\x00\xf3'
Note though that for this method you need to specify the length in bits of the bitstring you are creating.
Internally this is pretty much the same as Alex's answer, but the module has a lot of extra functionality available if you want to do more with your data.
To reset your keyring.
Go into your home folder.
Press ctrl & h to show your hidden folders.
Now look in your .gnome2/keyrings directory.
Find the default.keyring file.
Move that file to a different folder.
Once done, reboot your computer.
You can use Jackson Mixins. For example:
class YourClass {
public int ignoreThis() { return 0; }
}
With this Mixin
abstract class MixIn {
@JsonIgnore abstract int ignoreThis(); // we don't need it!
}
With this:
objectMapper.getSerializationConfig().addMixInAnnotations(YourClass.class, MixIn.class);
Edit:
Thanks to the comments, with Jackson 2.5+, the API has changed and should be called with objectMapper.addMixIn(Class<?> target, Class<?> mixinSource)
Both worked for me.

The following code will return a JavaScript Object containing the URL parameters:
// Read a page's GET URL variables and return them as an associative array.
function getUrlVars()
{
var vars = [], hash;
var hashes = window.location.href.slice(window.location.href.indexOf('?') + 1).split('&');
for(var i = 0; i < hashes.length; i++)
{
hash = hashes[i].split('=');
vars.push(hash[0]);
vars[hash[0]] = hash[1];
}
return vars;
}
For example, if you have the URL:
http://www.example.com/?me=myValue&name2=SomeOtherValue
This code will return:
{
"me" : "myValue",
"name2" : "SomeOtherValue"
}
and you can do:
var me = getUrlVars()["me"];
var name2 = getUrlVars()["name2"];
When you use Vector *one
you are merely creating a pointer to the structure but there is no memory allocated to it.
Simply use one = (Vector *)malloc(sizeof(Vector));
to declare memory and instantiate it.

I have found out that if you remove Microsoft.CSharp assembly as a reference in the project, you will get this error.
Note: This is Flask specific!
I know this post is quite old, but there are better methods of doing this in the newer versions of Flask using context processors.
Variables can easily be created:
@app.context_processor
def example():
return dict(myexample='This is an example')
The above can be used in a Jinja2 template with Flask like so:
{{ myexample }}
(Which outputs This is an example
)
As well as full fledged functions:
@app.context_processor
def utility_processor():
def format_price(amount, currency=u'€'):
return u'{0:.2f}{1}'.format(amount, currency)
return dict(format_price=format_price)
The above when used like so:
{{ format_price(0.33) }}
(Which outputs the input price with the currency symbol)
Alternatively, you can use jinja filters, baked into Flask. E.g. using decorators:
@app.template_filter('reverse')
def reverse_filter(s):
return s[::-1]
Or, without decorators, and manually registering the function:
def reverse_filter(s):
return s[::-1]
app.jinja_env.filters['reverse'] = reverse_filter
Filters applied with the above two methods can be used like this:
{% for x in mylist | reverse %}
{% endfor %}
It's a lot more simple that you think. You've signed into both your mobile and Chrome on your desktop using the same Google account. Google simply expect you will have your mobile with you most of the time. They take the location data from your phone and assume the location of your current desktop session is the same.
I proved this by RDPing into my Windows machine at home from work and checking Google maps remotely. It show my location as the same as Chrome on Linux at work.
If you don't have a mobile that is signed into Google then all they can do is lookup GeoIP data for the IP address assigned by your ISP. It will typically be wildly inaccurate.
In this case, ' is not a comment character. It's used to delimit string literals. The comic artist is banking on the idea that the school in question has dynamic sql somewhere that looks something like this:
$sql = "INSERT INTO `Students` (FirstName, LastName) VALUES ('" . $fname . "', '" . $lname . "')";
So now the ' character ends the string literal before the programmer was expecting it. Combined with the ; character to end the statement, an attacker can now add whatever sql they want. The -- comment at the end is to make sure any remaining sql in the original statement does not prevent the query from compiling on the server.
FWIW, I also think the comic in question has an important detail wrong: if you're thinking about sanitizing your database inputs, as the comic suggests, you're still doing it wrong. Instead, you should think in terms of quarantining your database inputs, and the correct way to do this is via parameterized queries.
This problem commonly occurs when switching from py2 to py3. In py2 plaintext
is both a string and a byte array type. In py3 plaintext
is only a string, and the method outfile.write()
actually takes a byte array when outfile
is opened in binary mode, so an exception is raised. Change the input to plaintext.encode('utf-8')
to fix the problem. Read on if this bothers you.
In py2, the declaration for file.write made it seem like you passed in a string: file.write(str)
. Actually you were passing in a byte array, you should have been reading the declaration like this: file.write(bytes)
. If you read it like this the problem is simple, file.write(bytes)
needs a bytes type and in py3 to get bytes out of a str you convert it:
py3>> outfile.write(plaintext.encode('utf-8'))
Why did the py2 docs declare file.write
took a string? Well in py2 the declaration distinction didn't matter because:
py2>> str==bytes #str and bytes aliased a single hybrid class in py2
True
The str-bytes class of py2 has methods/constructors that make it behave like a string class in some ways and a byte array class in others. Convenient for file.write
isn't it?:
py2>> plaintext='my string literal'
py2>> type(plaintext)
str #is it a string or is it a byte array? it's both!
py2>> outfile.write(plaintext) #can use plaintext as a byte array
Why did py3 break this nice system? Well because in py2 basic string functions didn't work for the rest of the world. Measure the length of a word with a non-ASCII character?
py2>> len('¡no') #length of string=3, length of UTF-8 byte array=4, since with variable len encoding the non-ASCII chars = 2-6 bytes
4 #always gives bytes.len not str.len
All this time you thought you were asking for the len of a string in py2, you were getting the length of the byte array from the encoding. That ambiguity is the fundamental problem with double-duty classes. Which version of any method call do you implement?
The good news then is that py3 fixes this problem. It disentangles the str and bytes classes. The str class has string-like methods, the separate bytes class has byte array methods:
py3>> len('¡ok') #string
3
py3>> len('¡ok'.encode('utf-8')) #bytes
4
Hopefully knowing this helps de-mystify the issue, and makes the migration pain a little easier to bear.

Mr Expensive Toys said: Am amazed that this problem is still showing up as it started happening as far back as Honeycomb.
So, the /storage/emulated/0/DCIM/Camera is the same folder as your normal DCIM/Camera folder. Its just a symlink. So the files are actually in the right location you just have an app that put bad data into the MediaStore Database.
When accessing files from your PC your are actually enumerating the MediaStorage database for files. Its not pulling a traditional directory lists. So what you see is based on what is in that database and the path entries in the database. Files in the database pointing to emulated directories aren't shown as they are assumed to be duplicates as its the same physical directory as your normal DCIM/Camera. What is going on is that some poorly written third party apps are inserting entries into the database with the /storage/emulated/0/DCIM/Camera path instead of the proper root path to DCIM/Camera. Which means that the MTP service can't see them when you are hooked up to your PC.
Usually the easiest way to fix the problem is to just clear the MediaStore databases to get the bad entries out of the MediaStore Database and let the system reindex the files and put into the database with the proper paths.
Settings->apps Hit 3 dot menu in top right and select Show System Find Media Storage, Select it, Select Storage, then Clear Data Find External Storage, Select it , Select Storage, then Clear Data Turn phone off, turn phone back on, wait for indexer service to rebuild the data.
When you are done the files should show up with proper directory tree and be visible from the PC. Depending on amount of files on the phone it can take as 10-20 minutes to rebuild the media database as the service walks the phone directories, getting meta data, creating thumbnails, etc.
Copyright should be up to the date of publish.
So, if it's a static content (such as the Times article you linked to), it should probably be statically copyrighted.
If it's dynamically generated content, it should be copyrighted to the current year
An easy way I'm using:
file_put_contents($output_file, file_get_contents($base64_string));
This works well because file_get_contents
can read data from a URI, including a data:// URI.
A nice option is to use tar -tvvf <filePath>
which adds a line that reports the kind of file.
Example in a valid .tar file:

If you're using jQuery, you can use extend
myElement.id =0;
myElement.value=1;
myArray[0] = $.extend({}, myElement);
myElement.id = 2;
myElement.value = 3;
myArray[1] = $.extend({}, myElement);

This will return

There's no point in declaring the class as static
. Just declare its methods static
and call them from the class name as normal, like Java's Math class.
Also, even though it isn't strictly necessary to make the constructor private, it is a good idea to do so. Marking the constructor private prevents other people from creating instances of your class, then calling static methods from those instances. (These calls work exactly the same in Java, they're just misleading and hurt the readability of your code.)

R.java is an autogenerated file, it usually does not get compiled if you have errors in xml file.
No You cannot write your own R.java file, it has to be generated by the resource compiler.
Check for errors in all your xml files.
Okay, redis is pretty user friendly but there are some gotchas.
Here are just some easy commands for working with redis on Ubuntu:
install:
sudo apt-get install redis-server
start with conf:
sudo redis-server <path to conf>
sudo redis-server config/redis.conf
stop with conf:
redis-ctl shutdown
(not sure how this shuts down the pid specified in the conf. Redis must save the path to the pid somewhere on boot)
log:
tail -f /var/log/redis/redis-server.log
Also, various example confs floating around online and on this site were beyond useless. The best, sure fire way to get a compatible conf is to copy-paste the one your installation is already using. You should be able to find it here:
/etc/redis/redis.conf
Then paste it at <path to conf>
, tweak as needed and you're good to go.
In my case I was using the MailMessage constructor that takes two strings (to, from) and getting the same error. When I used the default constructor and then added a MailAddress object to the To property of the MailMessage it worked fine.
Here is another solution using Jquery I find it a little easier and neater than inline JS sometimes.
<html>
<head>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.1/jquery.min.js"></script>
<script>
/* if you prefer to functionize and use onclick= rather then the .on bind
function hide_show(){
$(this).hide();
$("#hidden-div").show();
}
*/
$(function(){
$("#chkbtn").on('click',function() {
$(this).hide();
$("#hidden-div").show();
});
});
</script>
<style>
.hidden-div {
display:none
}
</style>
</head>

One possible approach is to simply include gson
dependency:
<dependency>
<groupId>com.google.code.gson</groupId>
<artifactId>gson</artifactId>
</dependency>
and parse the value to make your verifications:
@RunWith(SpringRunner.class)
@WebMvcTest(HelloController.class)
public class HelloControllerTest {
@Autowired
private MockMvc mockMvc;
@MockBean
private HelloService helloService;
@Before
public void before() {
Mockito.when(helloService.message()).thenReturn("hello world!");
}
@Test
public void testMessage() throws Exception {
MvcResult mvcResult = mockMvc.perform(MockMvcRequestBuilders.get("/"))
.andExpect(status().isOk())
.andExpect(content().contentTypeCompatibleWith(MediaType.APPLICATION_JSON_VALUE))
.andReturn();
String responseBody = mvcResult.getResponse().getContentAsString();
ResponseDto responseDto
= new Gson().fromJson(responseBody, ResponseDto.class);
Assertions.assertThat(responseDto.message).isEqualTo("hello world!");
}
}
Stupid as it may sound but all "Provisioning Profiles" re-appear under "Organizer - Devices" once you connect a real device.
This was written quickly, and is neither pretty nor efficient (plus it autoboxes alot, converting between int
and Integer
is annoying!), but it works.
It probably breaks the rules since I'm creating my own objects but hey I'm doing this as a diversion from real work :)
This also assumes that the resultSet/table is completely read into some sort of structure before you start building Nodes, which wouldn't be the best solution if you have hundreds of thousands of rows.
public class Node {
private Node parent = null;

Map<Integer, Integer> childParentMap = new HashMap<Integer, Integer>();
// create special 'root' Node with id=0
Node root = new Node(null, 0, "root");
nodeMap.put(root.getId(), root);

Node node = new Node(null, id, name);

The tricky part here is to handle is the page event. We can follow angular material documentation up to defining page event function.
Visit https://material.angular.io/components/paginator/examples for the reference.
I will add my work with hours of hard work in this regard. in the relevant HTML file should look like as follows,
<pre>
<mat-paginator
[pageSizeOptions]="pageSizeOptions"
[pageSize]="Size"
(page)="pageEvent = pageNavigations($event)"
[length]="recordCount">
</mat-paginator>
</pre>
Then go to the relevant typescript file and following code,
declarations,
@Input('data') customers: Observable<Customer[]>;
pageEvent: PageEvent;
Page: number=0;
Size: number=2;
recordCount: number;
pageSizeOptions: number[] = [2,3,4,5];
The key part of page navigation as follows,
pageNavigations(event? : PageEvent){
console.log(event);
this.Page = event.pageIndex;
this.Size = event.pageSize;
this.reloadData();
}
We require the following function to call data from the backend.
reloadData() {
this.customers = this.customerService.setPageSize(this.Page ,this.Size);
this.customerService.getSize().subscribe(res => {
this.recordCount = Number(res);
console.log(this.recordCount);
});
}
Before the aforementioned implementation, our services file should contain the following service call
setPageSize(page: number, size: number): Observable<any> {
return this.http.get(`${this.baseUrl}?pageSize=${size}&pageNo=${page}`);
}
Then all set to go and enable pagination in our app. Feel free to ask related questions thank you.
Doctrine is probably your best bet. Prior to Doctrine, DB_DataObject was essentially the only other utility that was open sourced.
Using below query you can remove leading and trailing whitespace in a MySQL.
UPDATE `table_name`
SET `col_name` = TRIM(`col_name`);
You can't checkout a single directory of a repository because the entire repository is handled by the single .git folder in the root of the project instead of subversion's myriad of .svn directories.
The problem with working on plugins in a single repository is that making a commit to, e.g., mytheme will increment the revision number for myplugin, so even in subversion it is better to use separate repositories.
The subversion paradigm for sub-projects is svn:externals which translates somewhat to submodules in git (but not exactly in case you've used svn:externals before.)
Because they're writing a plugin and C++ has no standard ABI.
How about this?
<div class="relative">
<div class="yellow-div"></div>
<div class="yellow-div"></div>
<div class="absolute"></div>
</div>
.relative{
position:relative;
}
.absolute {
position:absolute;
width: 40px;
height: 100px;
background: #000;
z-index: 1;
top:30px;
left:0px;
}
.yellow-div {
position:relative;
width: 200px;
height: 50px;
background: yellow;
margin-bottom:4px;
z-index:0;
}
use the relative div as wrapper and let the yellow div's have normal positioning.
Only the black block need to have an absolute position then.
You need to call self.a()
to invoke a
from b
. a
is not a global function, it is a method on the class.
You may want to read through the Python tutorial on classes some more to get the finer details down.
This is how you can dynamically create a class named Child
in your code, assuming Parent
already exists... even if you don't have an explicit Parent
class, you could use object
...
The code below defines __init__()
and then associates it with the class.
>>> child_name = "Child"
>>> child_parents = (Parent,)
>>> child body = """
def __init__(self, arg1):
# Initialization for the Child class
self.foo = do_something(arg1)
"""
>>> child_dict = {}
>>> exec(child_body, globals(), child_dict)
>>> childobj = type(child_name, child_parents, child_dict)
>>> childobj.__name__
'Child'
>>> childobj.__bases__
(<type 'object'>,)
>>> # Instantiating the new Child object...
>>> childinst = childobj()
>>> childinst
<__main__.Child object at 0x1c91710>
>>>
1) You can use an Align widget, with FractionalOffset.bottomCenter
.
2) You can also set left: 0.0
and right: 0.0
in the Positioned
.
I think np.isnan(np.min(X))
should do what you want.
The format you need is:
'2007-01-01 10:00:00'
i.e. yyyy-MM-dd HH:mm:ss
If possible, however, use a parameterised query as this frees you from worrying about the formatting details.
You should provide output file name after -o
option. In your case runexp.o
is treated as output file name, not input object file and thus your main
function is undefined.
java.math.BigInteger
is an immutable class so we can not assign new object in the location of already assigned object. But you can create new object to assign new value like:
sum = sum.add(BigInteger.valueOf(i));
the 0.44 is ok to run,but 0.45 can not,maybe is the version problem i solved this by the following command: rninit init TaxiApp --source [email protected];
If your address1 = '123 Center St'
and address2 = 'Apt 3B'
then even if you combine and do a LIKE
, you cannot search on searchstring as 'Center St 3B'
. However, if your searchstring was 'Center St Apt'
, then you can do it using -
WHERE (address1 + ' ' + address2) LIKE '%searchstring%'
If you have it available, using curl is your best option.
You can see if it is enabled by doing phpinfo()
and searching the page for curl.
If it is enabled, try this:
$curl_handle=curl_init();
curl_setopt($curl_handle, CURLOPT_URL, SITE_PATH . 'cms/data.php');
$xml_file = curl_exec($curl_handle);
curl_close($curl_handle);
One general procedure is laid out in the Wikipedia article on unsharp masking:
You use a Gaussian smoothing filter and subtract the smoothed version from the original image (in a weighted way so the values of a constant area remain constant).
To get a sharpened version of frame
into image
: (both cv::Mat
)
cv::GaussianBlur(frame, image, cv::Size(0, 0), 3);
cv::addWeighted(frame, 1.5, image, -0.5, 0, image);
The parameters there are something you need to adjust for yourself.
There's also Laplacian sharpening, you should find something on that when you google.
$mysearch="Your Search Name";
$query = mysql_query("SELECT * FROM table");
$c=0;
// set array
$array = array();
// look through query
while($row = mysql_fetch_assoc($query)){
// add each row returned into an array
$array[] = $row;
$c++;
}
for($i=0;$i=$c;$i++)
{
if($array[i]['username']==$mysearch)
{
// name found
}
}
You can only use Core Graphics (Quartz, 2D only) transforms directly applied to a UIView's transform property. To get the effects in coverflow, you'll have to use CATransform3D, which are applied in 3-D space, and so can give you the perspective view you want. You can only apply CATransform3Ds to layers, not views, so you're going to have to switch to layers for this.
Check out the "CovertFlow" sample that comes with Xcode. It's mac-only (ie not for iPhone), but a lot of the concepts transfer well.
To stop Jenkins Please avoid shutting down the Java process or the Windows service. These are not usual commands. Use those only if your Jenkins is causing problems.
Use Jenkins' way to stop that protects from data loss.
http://[jenkins-server]/[command]
where [command] can be any one of the following
Example: if my local PC is running Jenkins at port 8080, it will be
http://localhost:8080/exit
If you have docker installed you can do something like:
$ docker run postgres:9.2 pg_dump books > books.out
That will download the Docker container with Postgres 9.2 in it, run pg_dump
inside of the container, and write the output.
You can use fall-through method in switch case.
const x = 'Welcome';
switch (x) {
case 'Come':
console.log(1)
break;
case 'Welcome':
case 'Wel':
case 'come':
console.log(2)
break;
case 'Wel':
console.log(3)
break;
default:
break;
}
> Result => 2
I was writing up an answer to a similar question that got deleted, so I'm posting it here in case it's of use to anyone.
The markup can be dropped in anywhere and takes up 50px of vertical real estate even when hidden. (To have it take up no vertical space and instead overlay the top 50px, we can just give the progressContainerDiv
absolute positioning (inside any positioned element) and style the display
property instead of the visible
property.)
The general structure is based on code presented in this Geeks for Geeks article.

To call a web service from a mobile device (especially on an Android phone), I have used a very simple way to do it. I have not used any web service client API in attempt to call the web service. My approach is as follows to make a call.
HttpURLConnection
.getResonseCode
).ErrorInput
stream on
same HTTPobject and receive the
error if any.I have implemented this procedure for the Android phone, and it is successfully running. I am able to parse the response even if it is more than 700 KB.
If you want to generate a file in the Windows, then, please follow the below steps:
Update: The generated file will not be a valid pdf file. It just holds the given size.
When you're using HttpWebRequest and POST method, you have to set a content (or a body if you prefer) via the RequestStream. But, according to your code, using authRequest.Method = "GET" should be enough.
In case you're wondering about POST format, here's what you have to do :
ASCIIEncoding encoder = new ASCIIEncoding();
byte[] data = encoder.GetBytes(serializedObject); // a json object, or xml, whatever...
HttpWebRequest request = WebRequest.Create(url) as HttpWebRequest;
request.Method = "POST";
request.ContentType = "application/json";
request.ContentLength = data.Length;
request.Expect = "application/json";
request.GetRequestStream().Write(data, 0, data.Length);
HttpWebResponse response = request.GetResponse() as HttpWebResponse;
Using from your_file import *
should fix your problems. It defines everything so that it is globally available (with the exception of local variables in the imports of course).
for example:
##test.py:
from pytest import *
print hello_world
and:
##pytest.py
hello_world="hello world!"
First run
mysqld -u root --initialize-insecure
It will create data folder with root as user without password. Then run
mysqld.exe -u root --console
You do not define a binding in your service's config, so you are getting the default values for wsHttpBinding
, and the default value for securityMode\transport
for that binding is Message
.
Try copying your binding configuration from the client's config to your service config and assign that binding to the endpoint via the bindingConfiguration
attribute:
<bindings>
<wsHttpBinding>
<binding name="ota2010AEndpoint"
.......>
<readerQuotas maxDepth="32" ... />
<reliableSession ordered="true" .... />
<security mode="Transport">
<transport clientCredentialType="None" proxyCredentialType="None"
realm="" />
<message clientCredentialType="Windows" negotiateServiceCredential="true"
establishSecurityContext="true" />
</security>
</binding>
</wsHttpBinding>
</bindings>
(Snipped parts of the config to save space in the answer).
<service name="Synxis" behaviorConfiguration="SynxisWCF">
<endpoint address="" name="wsHttpEndpoint"
binding="wsHttpBinding"
bindingConfiguration="ota2010AEndpoint"
contract="Synxis" />
This will then assign your defined binding (with Transport security) to the endpoint.
I believe this is the easiest and fastest one:
cat file.txt | grep .
If you need to ignore all white-space lines as well then try this:
cat file.txt | grep '\S'
Example:
s="\
\
a\
b\
\
Below is TAB:\
\
Below is space:\
\
c\
\
"; echo "$s" | grep . | wc -l; echo "$s" | grep '\S' | wc -l
outputs

Step by step guide to install Python 3.6 and pip3 in Ubuntu
Install the necessary packages for Python and ssl: $ sudo apt-get install libreadline-gplv2-dev libncursesw5-dev libssl-dev libsqlite3-dev tk-dev libgdbm-dev libc6-dev libbz2-dev
Download and unzip "Python-3.6.8.tar.xz" from https://www.python.org/ftp/python/ into your home directory.
Open terminal in that directory and run: $ ./configure
Build and install: $ make && sudo make install
Install packages with: $ pip3 install package_name
Disclaimer: The above commands are not tested in Ubuntu 20.04 LTS.
You'll need to add a reference to System.Configuration
in your project's references folder.
You should definitely be using the ConfigurationManager
over the obsolete ConfigurationSettings
.
The only subquery appears to be this - try adding a ROWNUM
limit to the where to be sure:
(SELECT C.I_WORKDATE
FROM T_COMPENSATION C
WHERE C.I_COMPENSATEDDATE = A.I_REQDATE AND ROWNUM <= 1
AND C.I_EMPID = A.I_EMPID)
You do need to investigate why this isn't unique, however - e.g. the employee might have had more than one C.I_COMPENSATEDDATE
on the matched date.
For performance reasons, you should also see if the lookup subquery can be rearranged into an inner / left join, i.e.
SELECT
...
REPLACE(TO_CHAR(C.I_WORKDATE, 'DD-Mon-YYYY'),
' ',
'') AS WORKDATE,
...
INNER JOIN T_EMPLOYEE_MS E
...
LEFT OUTER JOIN T_COMPENSATION C
ON C.I_COMPENSATEDDATE = A.I_REQDATE
AND C.I_EMPID = A.I_EMPID
...
You want the :checkbox:checked
selector and map
to create an array of the values:
var checkedValues = $('input:checkbox:checked').map(function() {
return this.value;
}).get();
If your checkboxes have a shared class it would be faster to use that instead, eg. $('.mycheckboxes:checked')
, or for a common name $('input[name="Foo"]:checked')
- Update -
If you don't need IE support then you can now make the map()
call more succinct by using an arrow function:
var checkedValues = $('input:checkbox:checked').map((i, el) => el.value).get();
Try to use it, and trap for the error. The allowed set may change across file systems, or across different versions of Windows. In other words, if you want know if Windows likes the name, hand it the name and let it tell you.
If you are OK to run Java command line then you can do it with Apache POI HSSF's Excel Extractor. It has a main
method that says to be the command line extractor. This one seems to just dump everything out. They point out to this example that converts to CSV. You would have to compile it before you can run it but it too has a main
method so you should not have to do much coding per se to make it work.
Another option that might fly but will require some work on the other end is to make your Excel files come to you as Excel XML Data or XML Spreadsheet of whatever MS calls that format these days. It will open a whole new world of opportunities for you to slice and dice it the way you want.
Trying to work through Roman Pekar's solution step-by-step to understand it better, I came up with my own solution, which uses melt
to avoid some of the confusing stacking and index resetting. I can't say that it's obviously a clearer solution though:
items_as_cols = df.apply(lambda x: pd.Series(x['samples']), axis=1)
# Keep original df index as a column so it's retained after melt
items_as_cols['orig_index'] = items_as_cols.index
melted_items = pd.melt(items_as_cols, id_vars='orig_index',
var_name='sample_num', value_name='sample')
melted_items.set_index('orig_index', inplace=True)
df.merge(melted_items, left_index=True, right_index=True)
Output (obviously we can drop the original samples column now):
samples subject trial_num sample_num sample
0 [1.84, 1.05, -0.66] 1 1 0 1.84
0 [1.84, 1.05, -0.66] 1 1 1 1.05
0 [1.84, 1.05, -0.66] 1 1 2 -0.66

You'll first get the dropdown element from the DOM, then loop through the array, and add each element as a new option in the dropdown like this:
// Get dropdown element from DOM
var dropdown = document.getElementById("selectNumber");
// Loop through the array
for (var i = 0; i < myArray.length; ++i) {
// Append the element to the end of Array list
dropdown[dropdown.length] = new Option(myArray[i], myArray[i]);
}?
See JSFiddle for a live demo: http://jsfiddle.net/nExgJ/
This assumes that you're not using JQuery, and you only have the basic DOM API to work with.
Version without subselect:
SELECT f.title,
f.content,

LEFT JOIN artists a ON fa.artist_id = a.artist_id
GROUP BY f.id
You might be after something that the scrollTo plugin from Ariel Flesler does really well.
You can declare a @service as @Controller.
You can NOT declare an @Controller as @Service
@Service
It is regular. You are just declaring class as a Component.
@Controller
It is a little more special than Component. The dispatcher will search for @RequestMapping here. So a class annotated with @Controller, will be additionally empowered with declaring URLs through which APIs are called
You can use np.concatenate()
specifying which axis
to append, using np.newaxis
:
import numpy as np
movie = np.concatenate((img1[:,np.newaxis], img2[:,np.newaxis]), axis=3)
If you are reading from many files:
import glob
movie = np.concatenate([cv2.imread(p)[:,np.newaxis] for p in glob.glob('*.jpg')], axis=3)
You can use a method reference:
import static java.util.Comparator.*;
import static java.util.stream.Collectors.*;
Arrays.asList(files).stream()
.filter(file -> isNameLikeBaseLine(file, baseLineFile.getName()))
.sorted(comparing(File::lastModified).reversed())
.skip(numOfNewestToLeave)
.forEach(item -> item.delete());
In alternative of method reference you can use a lambda expression, so the argument of comparing become:
.sorted(comparing(file -> file.lastModified()).reversed());
You can do it multiple ways. Here are two. Cheers!

I have just copied UUID toString() method and just updated it to remove "-" from it. It will be much more faster and straight forward than any other solution
public String generateUUIDString(UUID uuid) {
return (digits(uuid.getMostSignificantBits() >> 32, 8) +
digits(uuid.getMostSignificantBits() >> 16, 4) +
digits(uuid.getMostSignificantBits(), 4) +
digits(uuid.getLeastSignificantBits() >> 48, 4) +
digits(uuid.getLeastSignificantBits(), 12));
}
/** Returns val represented by the specified number of hex digits. */
private String digits(long val, int digits) {
long hi = 1L << (digits * 4);
return Long.toHexString(hi | (val & (hi - 1))).substring(1);
}
Usage:
generateUUIDString(UUID.randomUUID())
Another implementation using reflection
public String generateString(UUID uuid) throws NoSuchMethodException, InvocationTargetException, IllegalAccessException {
if (uuid == null) {
return "";
}
Method digits = UUID.class.getDeclaredMethod("digits", long.class, int.class);
digits.setAccessible(true);
return ( (String) digits.invoke(uuid, uuid.getMostSignificantBits() >> 32, 8) +
digits.invoke(uuid, uuid.getMostSignificantBits() >> 16, 4) +
digits.invoke(uuid, uuid.getMostSignificantBits(), 4) +
digits.invoke(uuid, uuid.getLeastSignificantBits() >> 48, 4) +
digits.invoke(uuid, uuid.getLeastSignificantBits(), 12));
}
Well, there are plenty of database tutorials online for java (what you're looking for is called JDBC). But if you are using plain servlets, you will have a class that extends HttpServlet
and inside it you will have two methods that look like
public void doPost(HttpServletRequest req, HttpServletResponse resp){
}
and
public void doGet(HttpServletRequest req, HttpServletResponse resp){
}
One of them is called to handle GET
operations and another is used to handle POST
operations. You will then use the HttpServletRequest
object to get the parameters that were passed as part of the form like so:
String name = req.getParameter("name");
Then, once you have the data from the form, it's relatively easy to add it to a database using a JDBC tutorial that is widely available on the web. I also suggest searching for a basic Java servlet tutorial to get you started. It's very easy, although there are a number of steps that need to be configured correctly.
Have you tried the Generate Scripts
(Right click, tasks, generate scripts) option in SQL Management Studio? Does that produce what you mean by a "SQL File"?
WARNING: Necromancing
Still Darin Dimitrov's answer + System.Security.SecurityElement.Escape(string s) isn't complete.
In XML 1.1, the simplest and safest way is to just encode EVERYTHING.
Like 	
for \t.
It isn't supported at all in XML 1.0.
For XML 1.0, one possible workaround is to base-64 encode the text containing the character(s).
//string EncodedXml = SpecialXmlEscape("?????? ???");
//Console.WriteLine(EncodedXml);
//string DecodedXml = XmlUnescape(EncodedXml);
//Console.WriteLine(DecodedXml);
public static string SpecialXmlEscape(string input)
{
//string content = System.Xml.XmlConvert.EncodeName("\t");
//string content = System.Security.SecurityElement.Escape("\t");
//string strDelimiter = System.Web.HttpUtility.HtmlEncode("\t"); // XmlEscape("\t"); //XmlDecode("	");
//strDelimiter = XmlUnescape(";");
//Console.WriteLine(strDelimiter);
//Console.WriteLine(string.Format("&#{0};", (int)';'));
//Console.WriteLine(System.Text.Encoding.ASCII.HeaderName);
//Console.WriteLine(System.Text.Encoding.UTF8.HeaderName);
string strXmlText = "";
if (string.IsNullOrEmpty(input))
return input;
System.Text.StringBuilder sb = new StringBuilder();
for (int i = 0; i < input.Length; ++i)
{
sb.AppendFormat("&#{0};", (int)input[i]);
}
strXmlText = sb.ToString();
sb.Clear();
sb = null;
return strXmlText;
} // End Function SpecialXmlEscape
XML 1.0:
public static string Base64Encode(string plainText)
{
var plainTextBytes = System.Text.Encoding.UTF8.GetBytes(plainText);
return System.Convert.ToBase64String(plainTextBytes);
}
public static string Base64Decode(string base64EncodedData)
{
var base64EncodedBytes = System.Convert.FromBase64String(base64EncodedData);
return System.Text.Encoding.UTF8.GetString(base64EncodedBytes);
}
In PHP there is a pretty good function utf8_encode() to solve this issue.
echo utf8_encode("Résumé");
//will output Résumé instead of R?sum?
If you want to modify a control it must be done in the thread in which the control was created. This Invoke
method allows you to execute methods in the associated thread (the thread that owns the control's underlying window handle).
In below sample thread1 throws an exception because SetText1 is trying to modify textBox1.Text from another thread. But in thread2, Action in SetText2 is executed in the thread in which the TextBox was created
private void btn_Click(object sender, EvenetArgs e)
{
var thread1 = new Thread(SetText1);
var thread2 = new Thread(SetText2);
thread1.Start();
thread2.Start();
}
private void SetText1()
{
textBox1.Text = "Test";
}
private void SetText2()
{
textBox1.Invoke(new Action(() => textBox1.Text = "Test"));
}
If you are using Forms
you can use the icon setting in the properties pane. To do this select the form and scroll down in the properties pane till you see the icon setting. When you open the application it will have the icon wherever you have it in your application and in the task bar
try the below code
execute immediate 'truncate table tablename' ;
Try this code.
public void send (String fileName) {
String SFTPHOST = "host:IP";
int SFTPPORT = 22;
String SFTPUSER = "username";
String SFTPPASS = "password";
String SFTPWORKINGDIR = "file/to/transfer";
Session session = null;
Channel channel = null;
ChannelSftp channelSftp = null;
System.out.println("preparing the host information for sftp.");
try {
JSch jsch = new JSch();
session = jsch.getSession(SFTPUSER, SFTPHOST, SFTPPORT);
session.setPassword(SFTPPASS);
java.util.Properties config = new java.util.Properties();
config.put("StrictHostKeyChecking", "no");
session.setConfig(config);
session.connect();
System.out.println("Host connected.");
channel = session.openChannel("sftp");
channel.connect();
System.out.println("sftp channel opened and connected.");
channelSftp = (ChannelSftp) channel;
channelSftp.cd(SFTPWORKINGDIR);
File f = new File(fileName);
channelSftp.put(new FileInputStream(f), f.getName());
log.info("File transfered successfully to host.");
} catch (Exception ex) {
System.out.println("Exception found while tranfer the response.");
} finally {
channelSftp.exit();
System.out.println("sftp Channel exited.");
channel.disconnect();
System.out.println("Channel disconnected.");
session.disconnect();
System.out.println("Host Session disconnected.");
}
}

npm build
no longer exists. You must call npm run build
now. More info below.
npm install
: installs dependencies, then calls the install
from the package.json
scripts
field.
npm run build
: runs the build field from the package.json
scripts
field.
https://docs.npmjs.com/misc/scripts
There are many things you can put into the npm package.json
scripts field. Check out the documentation link above more above the lifecycle of the scripts - most have pre and post hooks that you can run scripts before/after install, publish, uninstall, test, start, stop, shrinkwrap, version.
npm install
is not the same as npm run install
npm install
installs package.json
dependencies, then runs the package.json
scripts.install
npm run install
after dependencies are installed.npm run install
only runs the package.json
scripts.install
, it will not install dependencies.npm build
used to be a valid command (used to be the same as npm run build
) but it no longer is; it is now an internal command. If you run it you'll get: npm WARN build npm build called with no arguments. Did you mean to npm run-script build?
You can read more on the documentation: https://docs.npmjs.com/cli/buildThere are still two top level commands that will run scripts, they are:
npm start
which is the same as npm run start
npm test
==> npm run test
I think much has already been said, about RSS vs VSZ. From an administrator/programmer/user perspective, when I design/code applications I am more concerned about the RSZ, (Resident memory), as and when you keep pulling more and more variables (heaped) you will see this value shooting up. Try a simple program to build malloc based space allocation in loop, and make sure you fill data in that malloc'd space. RSS keeps moving up. As far as VSZ is concerned, it's more of virtual memory mapping that linux does, and one of its core features derived out of conventional operating system concepts. The VSZ management is done by Virtual memory management of the kernel, for more info on VSZ, see Robert Love's description on mm_struct and vm_struct, which are part of basic task_struct data structure in kernel.
To check for null SPECIFICALLY you would use this:
if (variable === null)
This test will ONLY pass for null
and will not pass for ""
, undefined
, false
, 0
, or NaN
.
Additionally, I've provided absolute checks for each "false-like" value (one that would return true for !variable
).
Note, for some of the absolute checks, you will need to implement use of the absolutely equals: ===
and typeof
.
I've created a JSFiddle here to show all of the individual tests working
Here is the output of each check:
Null Test:
if (variable === null)
- variable = ""; (false) typeof variable = string
- variable = null; (true) typeof variable = object
- variable = undefined; (false) typeof variable = undefined
- variable = false; (false) typeof variable = boolean
- variable = 0; (false) typeof variable = number
- variable = NaN; (false) typeof variable = number
Empty String Test:
if (variable === '')
- variable = ''; (true) typeof variable = string
- variable = null; (false) typeof variable = object
- variable = undefined; (false) typeof variable = undefined
- variable = false; (false) typeof variable = boolean
- variable = 0; (false) typeof variable = number
- variable = NaN; (false) typeof variable = number
Undefined Test:
if (typeof variable == "undefined")
-- or --
if (variable === undefined)
- variable = ''; (false) typeof variable = string
- variable = null; (false) typeof variable = object
- variable = undefined; (true) typeof variable = undefined
- variable = false; (false) typeof variable = boolean
- variable = 0; (false) typeof variable = number
- variable = NaN; (false) typeof variable = number
False Test:
if (variable === false)
- variable = ''; (false) typeof variable = string
- variable = null; (false) typeof variable = object
- variable = undefined; (false) typeof variable = undefined
- variable = false; (true) typeof variable = boolean
- variable = 0; (false) typeof variable = number
- variable = NaN; (false) typeof variable = number
Zero Test:
if (variable === 0)
- variable = ''; (false) typeof variable = string
- variable = null; (false) typeof variable = object
- variable = undefined; (false) typeof variable = undefined
- variable = false; (false) typeof variable = boolean
- variable = 0; (true) typeof variable = number
- variable = NaN; (false) typeof variable = number
NaN Test:
if (typeof variable == 'number' && !parseFloat(variable) && variable !== 0)
-- or --
if (isNaN(variable))
- variable = ''; (false) typeof variable = string
- variable = null; (false) typeof variable = object
- variable = undefined; (false) typeof variable = undefined
- variable = false; (false) typeof variable = boolean
- variable = 0; (false) typeof variable = number
- variable = NaN; (true) typeof variable = number
As you can see, it's a little more difficult to test against NaN
;
Rather going for pop up,I personally liked this solution, mentioned on this Question thread JavaScript: location.href to open in new window/tab?
$(document).on('click','span.external-link',function(){
var t = $(this),
URL = t.attr('data-href');
$('<a href="'+ URL +'" target="_blank">External Link</a>')[0].click();
});
Working example.
It's as simple as it name.
var means it can vary
val means invariable
iirc :
cat filename.txt | awk '{ print $2 $4 }'
or, as mentioned in the comments :
awk '{ print $2 $4 }' filename.txt
Your code works well you just mistyped this line of code:
document.getElementbyId('lc').appendChild(element);
change it with this: (The "B" should be capitalized.)
document.getElementById('lc').appendChild(element);
HERE IS MY EXAMPLE:
<html>_x000D_
<head>_x000D_
_x000D_
<script>_x000D_
_x000D_
function test() {_x000D_
_x000D_
var element = document.createElement("div");_x000D_
element.appendChild(document.createTextNode('The man who mistook his wife for a hat'));_x000D_
document.getElementById('lc').appendChild(element);_x000D_
_x000D_
}_x000D_
_x000D_
</script>_x000D_
_x000D_
</head>_x000D_
<body>_x000D_
<input id="filter" type="text" placeholder="Enter your filter text here.." onkeyup = "test()" />_x000D_
_x000D_
<div id="lc" style="background: blue; height: 150px; width: 150px;_x000D_
}" onclick="test();"> _x000D_
</div>_x000D_
</body>_x000D_

There are jQuery-plugins that help you achieve this like: http://ricostacruz.com/jquery.transit/
Use value(cellref)
on the side to evaluate the cells. Strings will produce the "#Value" error, but dates resolve to a number (e.g. 43173
).
Here is a more modern approach using the Standard PHP Library (SPL).
$dir = "path/to/directory";
$di = new RecursiveDirectoryIterator($dir, FilesystemIterator::SKIP_DOTS);
$ri = new RecursiveIteratorIterator($di, RecursiveIteratorIterator::CHILD_FIRST);
foreach ( $ri as $file ) {
$file->isDir() ? rmdir($file) : unlink($file);
}
return true;
The first line moves the cursor to the last non-empty row in the column. The second line prints that columns row.
Selection.End(xlDown).Select
MsgBox(ActiveCell.Row)
I am assuming you want to pass the database name as a parameter and not just run:
SELECT *
FROM DBName.sys.tables
WHERE Name LIKE '%XXX%'
If so, you could use dynamic SQL to add the dbname to the query:
DECLARE @DBName NVARCHAR(200) = 'YourDBName',
@TableName NVARCHAR(200) = 'SomeString';
IF NOT EXISTS (SELECT 1 FROM master.sys.databases WHERE Name = @DBName)
BEGIN
PRINT 'DATABASE NOT FOUND';
RETURN;
END;
DECLARE @SQL NVARCHAR(MAX) = ' SELECT Name
FROM ' + QUOTENAME(@DBName) + '.sys.tables
WHERE Name LIKE ''%'' + @Table + ''%''';
EXECUTE SP_EXECUTESQL @SQL, N'@Table NVARCHAR(200)', @TableName;
I like using Tiny Types which would wrap either a double, BigDecimal, or int as previous answers have suggested. (I would use a double unless precision problems crop up).
A Tiny Type gives you type safety so you don't confused a double money with other doubles.
You can do what you want, with one (important) caveat: the paths within your symbol can't be styled independently via external CSS -- you can only set the properties for the entire symbol with this method. So, if you have two paths in your symbol and want them to have different fill colors, this won't work, but if you want all your paths to be the same, this should work.
In your html file, you want something like this:
<style>
.fill-red { fill: red; }
.fill-blue { fill: blue; }
</style>
<a href="//www.example.com/">
<svg class="fill-red">
<use xlink:href="images/icons.svg#example"></use>
</svg>
</a>
And in the external SVG file you want something like this:
<svg xmlns="http://www.w3.org/2000/svg">
<symbol id="example" viewBox="0 0 256 256">
<path d="M120.... />
</symbol>
</svg>
Swap the class on the svg
tag (in your html) from fill-red
to fill-blue
and ta-da... you have blue instead of red.
You can partially get around the limitation of being able to target the paths separately with external CSS by mixing and matching the external CSS with some in-line CSS on specific paths, since the in-line CSS will take precedence. This approach would work if you're doing something like a white icon against a colored background, where you want to change the color of the background via the external CSS but the icon itself is always white (or vice-versa). So, with the same HTML as before and something like this svg code, you'll get you a red background and a white foreground path:
<svg xmlns="http://www.w3.org/2000/svg">
<symbol id="example" viewBox="0 0 256 256">
<path class="background" d="M120..." />
<path class="icon" style="fill: white;" d="M20..." />
</symbol>
</svg>
If you are using fish and you are using mac and you want to be able to switch between JDK's, then below works for me on mac.
@kenglxn's answer didn't work for me and I figured out it bcos didn't set -g which is global !
Put below under ~/.config/fish/config.fish
alias j8="jhome -v 1.8.0_162"
alias j9="jhome -v 9.0.1"
function jhome
set -g -x JAVA_HOME (/usr/libexec/java_home $argv)
echo "JAVA_HOME:" $JAVA_HOME
echo "java -version:"
java -version
end
funcsave jhome
To know which version /minor version you have installed, you can do :
/usr/libexec/java_home -V 579ms ? Wed 14 Feb 11:44:01 2018

You can add position: fixed;
with top left right bottom 0
attribute, that solution work on older browsers too.
If you want to embed it, add position: absolute;
to the wrapper, and position: relative
to the div outside of the wrapper.

First ensure that you're running the query under your user credentials, and also in the right database context.
USE YOUR_DATABASE_NAME;
Otherwise, sys.procedures won't return anything. Now run the query as below:
select * from sys.procedures p
join sys.syscomments s on p.object_id = s.id
where text like '%YOUR_TEXT%';
Another option is to use INFORMATION_SCHEMA.ROUTINES.ROUTINE_DEFINITION, but be aware that it only holds limited number of characters (i.e., first 4000 characters) of the routine.
select * from YOUR_DATABASE_NAME.INFORMATION_SCHEMA.ROUTINES
where ROUTINE_DEFINITION like '%YOUR_TEXT%';
I tested on Microsoft SQL Server 2008 R2 (SP1) - 10.50.2500.0 (X64)
If you really don't care about props then the widest possible type is React.ReactType
.
This would allow passing native dom elements as string. React.ReactType
covers all of these:
renderGreeting('button');
renderGreeting(() => 'Hello, World!');
renderGreeting(class Foo extends React.Component {
render() {
return 'Hello, World!'
}
});
Either way works, but many places have coding standards in place that will guide the developer one way or the other. If such a policy is not in place, just follow your heart. One thing, though, it REALLY helps the readability of the code if you do use it. especially if you are not following a naming convention on class-level variable names.
An SQL JOIN clause is used to combine rows from two or more tables, based on a common field between them.
There are different types of joins available in SQL:
INNER JOIN: returns rows when there is a match in both tables.
LEFT JOIN: returns all rows from the left table, even if there are no matches in the right table.
RIGHT JOIN: returns all rows from the right table, even if there are no matches in the left table.
FULL JOIN: It combines the results of both left and right outer joins.
The joined table will contain all records from both the tables and fill in NULLs for missing matches on either side.
SELF JOIN: is used to join a table to itself as if the table were two tables, temporarily renaming at least one table in the SQL statement.
CARTESIAN JOIN: returns the Cartesian product of the sets of records from the two or more joined tables.
WE can take each first four joins in Details :
We have two tables with the following values.
TableA
id firstName lastName
.......................................
1 arun prasanth
2 ann antony
3 sruthy abc
6 new abc
TableB
id2 age Place
................
1 24 kerala
2 24 usa
3 25 ekm
5 24 chennai
....................................................................
INNER JOIN
Note :it gives the intersection of the two tables, i.e. rows they have common in TableA and TableB
Syntax
SELECT table1.column1, table2.column2...
FROM table1
INNER JOIN table2
ON table1.common_field = table2.common_field;
Apply it in our sample table :
SELECT TableA.firstName,TableA.lastName,TableB.age,TableB.Place
FROM TableA
INNER JOIN TableB
ON TableA.id = TableB.id2;
Result Will Be
firstName lastName age Place
..............................................
arun prasanth 24 kerala
ann antony 24 usa
sruthy abc 25 ekm
LEFT JOIN
Note : will give all selected rows in TableA, plus any common selected rows in TableB.
Syntax
SELECT table1.column1, table2.column2...
FROM table1
LEFT JOIN table2
ON table1.common_field = table2.common_field;
Apply it in our sample table :
SELECT TableA.firstName,TableA.lastName,TableB.age,TableB.Place
FROM TableA
LEFT JOIN TableB
ON TableA.id = TableB.id2;
Result
firstName lastName age Place
...............................................................................
arun prasanth 24 kerala
ann antony 24 usa
sruthy abc 25 ekm
new abc NULL NULL
RIGHT JOIN
Note : will give all selected rows in TableB, plus any common selected rows in TableA.
Syntax
SELECT table1.column1, table2.column2...
FROM table1
RIGHT JOIN table2
ON table1.common_field = table2.common_field;
Apply it in our sample table :
SELECT TableA.firstName,TableA.lastName,TableB.age,TableB.Place
FROM TableA
RIGHT JOIN TableB
ON TableA.id = TableB.id2;
Result
firstName lastName age Place
...............................................................................
arun prasanth 24 kerala
ann antony 24 usa
sruthy abc 25 ekm
NULL NULL 24 chennai
FULL JOIN
Note :It will return all selected values from both tables.
Syntax
SELECT table1.column1, table2.column2...
FROM table1
FULL JOIN table2
ON table1.common_field = table2.common_field;
Apply it in our sample table :
SELECT TableA.firstName,TableA.lastName,TableB.age,TableB.Place
FROM TableA
FULL JOIN TableB
ON TableA.id = TableB.id2;
Result
firstName lastName age Place
...............................................................................
arun prasanth 24 kerala
ann antony 24 usa
sruthy abc 25 ekm
new abc NULL NULL
NULL NULL 24 chennai
Interesting Fact
For INNER joins the order doesn't matter
For (LEFT, RIGHT or FULL) OUTER joins,the order matter
Better to go check this Link it will give you interesting details about join order
I used the svn2git script and works like a charm.
Use this.Hide() instead of this.Close()
The linefeed character \n
is not the line separator in certain operating systems (such as windows, where it's "\r\n") - my suggestion is that you use \r\n
instead, then it'll both see the line-break with only \n
and \r\n
, I've never had any problems using it.
Also, you should look into using a StringBuilder
instead of concatenating the String
in the while-loop at BookCatalog.toString()
, it is a lot more effective. For instance:
public String toString() {
BookNode current = front;
StringBuilder sb = new StringBuilder();
while (current!=null){
sb.append(current.getData().toString()+"\r\n ");
current = current.getNext();
}
return sb.toString();
}
In an existing project a simple way to see the React version is to go to a render
method of any component and add:
<p>{React.version}</p>
This assumes you import React like this: import React from 'react'
class Hash
def to_params
params = ''
stack = []
each do |k, v|
if v.is_a?(Hash)
stack << [k,v]
elsif v.is_a?(Array)
stack << [k,Hash.from_array(v)]
else
params << "#{k}=#{v}&"
end
end
stack.each do |parent, hash|
hash.each do |k, v|
if v.is_a?(Hash)
stack << ["#{parent}[#{k}]", v]
else
params << "#{parent}[#{k}]=#{v}&"
end
end
end
params.chop!
params
end
def self.from_array(array = [])
h = Hash.new
array.size.times do |t|
h[t] = array[t]
end
h
end
end
I think you missed a equal sign at:
Cursor c = ourDatabase.query(DATABASE_TABLE, column, KEY_ROWID + "" + l, null, null, null, null);
Change to:
Cursor c = ourDatabase.query(DATABASE_TABLE, column, KEY_ROWID + " = " + l, null, null, null, null);
Adding this answer because only this method helped me.
I deleted the migrations
folder run makemigrations
and migrate
.
It still said: No migrations to apply.
I went to migrate
folder and opened the last created file,
comment the migration I wanted(It was detected and entered there)
and run migrate
again.
This basically editing the migrations file manually.
Do this only if you understand the file content.
In a browser like Chrome etc.:
ctrl + shift + c
);overflow: visible
on body element (for e.g., <body style="overflow: visible">
)overflow
property:
backspace
on your keyboard to remove it.ctrl + z
to undo whatever code you delete, or hit refresh to start over).Good luck!
The easiest way is to just click on the 'Console' icon in Eclipse, like this:

For those who using jenkins to run the play book, I just added to my jenkins job before running the ansible-playbook the he environment variable ANSIBLE_HOST_KEY_CHECKING = False For instance this:
export ANSIBLE_HOST_KEY_CHECKING=False
ansible-playbook 'playbook.yml' \
--extra-vars="some vars..." \
--tags="tags_name..." -vv
I am not sure what you mean by "dynamic". If you mean adding items to a dictionary at runtime, it is as easy as dictionary[key] = value
.
If you wish to create a dictionary with key,value to start with (at compile time) then use (surprise!)
dictionary[key] = value
You've created a new repository and added some files to the index, but you haven't created your first commit yet. After you've done:
git add a_text_file.txt
... do:
git commit -m "Initial commit."
... and those errors should go away.
alias_method new_method, old_method
old_method will be declared in a class or module which is being inherited now to our class where new_method will be used.
these can be variable or method both.
Suppose Class_1 has old_method, and Class_2 and Class_3 both of them inherit Class_1.
If, initialization of Class_2 and Class_3 is done in Class_1 then both can have different name in Class_2 and Class_3 and its usage.
I have found answers to my confusions.
There is a very important difference between the root
and the alias
directives. This difference exists in the way the path specified in the root
or the alias
is processed.
In case of the root
directive, full path is appended to the root including the location part, whereas in case of the alias
directive, only the portion of the path NOT including the location part is appended to the alias.
To illustrate:
Let's say we have the config
location /static/ {
root /var/www/app/static/;
autoindex off;
}
In this case the final path that Nginx will derive will be
/var/www/app/static/static
This is going to return 404
since there is no static/
within static/
This is because the location part is appended to the path specified in the root
. Hence, with root
, the correct way is
location /static/ {
root /var/www/app/;
autoindex off;
}
On the other hand, with alias
, the location part gets dropped. So for the config
location /static/ {
alias /var/www/app/static/;
autoindex off; ?
} |
pay attention to this trailing slash
the final path will correctly be formed as
/var/www/app/static
alias
directiveThere is no definitive guideline about whether a trailing slash is mandatory per Nginx documentation, but a common observation by people here and elsewhere seems to indicate that it is.
A few more places have discussed this, not conclusively though.

I also get the same error in an ASP.NET application when I saved some unicode data (Hindi) in the Web.config file and saved it with "Unicode" encoding.
It fixed the error for me when I saved the Web.config file with "UTF-8" encoding.
