As of Express 4.x
app.js
// above is all your node requires
// view engine setup
app.set('views', path.join(__dirname, 'views')); <-- ./views has all your .ejs files
app.set('view engine', 'ejs');
error.ejs
<!-- because ejs knows your root directory for views, you can navigate to the ./base directory and select the header.ejs file and include it -->
<% include ./base/header %>
<h1> Other mark up here </h1>
<% include ./base/footer %>
Your problem is not actually specific to ejs.
2 things to note here
style.css is an external css file. So you dont need style tags inside that file. It should only contain the css.
In your express app, you have to mention the public directory from which you are serving the static files. Like css/js/image
it can be done by
app.use(express.static(__dirname + '/public'));
assuming you put the css files in public folder from in your app root. now you have to refer to the css files in your tamplate files, like
<link href="/css/style.css" rel="stylesheet" type="text/css">
Here i assume you have put the css file in css folder inside your public folder.
So folder structure would be
.
./app.js
./public
/css
/style.css
The custom style sheets that we have are static pages in our local file system. In order for server to serve static files, we have to use,
app.use(express.static("public"));
where,
public is a folder we have to create inside our root directory and it must have other folders like css, images.. etc
The directory structure would look like :
Then in your html file, refer to the style.css as
<link type="text/css" href="css/styles.css" rel="stylesheet">
@Nazar Medeiros - Your solution uses passport with Express. I am not using passport, just express-jwt. I might be doing something wrong, but when a user logs in, the token needs to return to the client side. From what I have found so far, this means we have to return a json with the token and therefor cannot call redirect. Is there something I am missing there?
To get around this, I simply return the token, store it in my cookies and then make a ajax GET request (with the valid token). When that ajax call returns I replace the body's html with the returned HTML. This is probably not the right way to do it, but I can't find a better way. Here is my JQuery JavaScript code.
function loginUser(){
$.post("/users/login", {
username: $( '#login_input_username' ).val(),
password: $( '#login_input_password' ).val()
}).done(function(res){
document.cookie = "token = " + res.token;
redirectToHome();
})
}
function redirectToHome(){
var settings = {
"async": true,
"crossDomain": true,
"url": "/home",
"type": "GET",
"headers": {
"authorization": "Bearer " + getCookie('token'),
"cache-control": "no-cache"
}
}
$.ajax(settings).done(function (response) {
$('body').replaceWith(response);
});
}
function getCookie(cname) {
var name = cname + "=";
var decodedCookie = decodeURIComponent(document.cookie);
var ca = decodedCookie.split(';');
for(var i = 0; i <ca.length; i++) {
var c = ca[i];
while (c.charAt(0) == ' ') {
c = c.substring(1);
}
if (c.indexOf(name) == 0) {
return c.substring(name.length, c.length);
}
}
return "";
}
JSON.stringify(data).length return string length not Object length, you can use Object.keys.
<% for(var i=0; i < Object.keys(data).length ; i++) {%>
You can also use else if
syntax:
<% if (x === 1) { %>
<p>Hello world!</p>
<% } else if (x === 2) { %>
<p>Hi earth!</p>
<% } else { %>
<p>Hey terra!</p>
<% } %>
Reinstalling npm, express and ejs fixed my problem
This one worked for me,
after that, the error was fixed.
With the differents answers, I implemented this code to use an external file JSON loaded in "app.locals"

a covering index is the one which gives every required column and in which SQL server don't have hop back to the clustered index to find any column. This is achieved using non-clustered index and using INCLUDE option to cover columns. Non-key columns can be included only in non-clustered indexes. Columns can’t be defined in both the key column and the INCLUDE list. Column names can’t be repeated in the INCLUDE list. Non-key columns can be dropped from a table only after the non-key index is dropped first. Please see details here
Paul Irish has a way to do this that covers most of the common problems. See his bullet-proof @font-face article:
The final variant, which stops unnecessary data from being downloaded by IE, and works in IE8, Firefox, Opera, Safari, and Chrome looks like this:
@font-face {
font-family: 'Graublau Web';
src: url('GraublauWeb.eot');
src: local('Graublau Web Regular'), local('Graublau Web'),
url("GraublauWeb.woff") format("woff"),
url("GraublauWeb.otf") format("opentype"),
url("GraublauWeb.svg#grablau") format("svg");
}
He also links to a generator that will translate the fonts into all the formats you need.
As others have already specified, this will only work in the latest generation of browsers. Your best bet is to use this in conjunction with something like Cufon, and only load Cufon if the browser doesn't support @font-face
.
You can check it by regular expression
public boolean isValid(String strEmail)
{
pattern = Pattern.compile("^[_A-Za-z0-9-\\+]+(\\.[_A-Za-z0-9-]+)*@[A-Za-z0-9-]+(\\.[A-Za-z0-9]+)*(\\.[A-Za-z]{2,})$");
matcher = pattern.matcher(strEmail);
if (strEmail.isEmpty()) {
return false;
} else if (!matcher.matches()) {
return false;
}
else
{
return true;
}
}
I've got a more performant solution compared to AlexZ's getComputedStyle() solution when one has position 'fixed' elements, if one is willing to ignore some edge cases (check comments):
function isVisible(el) {
/* offsetParent would be null if display 'none' is set.
However Chrome, IE and MS Edge returns offsetParent as null for elements
with CSS position 'fixed'. So check whether the dimensions are zero.
This check would be inaccurate if position is 'fixed' AND dimensions were
intentionally set to zero. But..it is good enough for most cases.*/
if (!el.offsetParent && el.offsetWidth === 0 && el.offsetHeight === 0) {
return false;
}
return true;
}
Side note: Strictly speaking, "visibility" needs to be defined first. In my case, I am considering an element visible as long as I can run all DOM methods/properties on it without problems (even if opacity is 0 or CSS visibility property is 'hidden' etc).
If choice
is available, use this:
choice /C X /T 10 /D X > nul
where /T 10
is the number of seconds to delay.
Note the syntax can vary depending on your Windows version, so use CHOICE /?
to be sure.
Aloha from 2018. Unfortunately, I don't have anything cool or futuristic to share with you.
I did however want to point out to those who have commented that the jQuery load()
method isn't working in the present are probably trying to use the method with local files without running a local web server. Doing so will throw the above mentioned "cross origin" error, which specifies that cross origin requests such as that made by the load method are only supported for protocol schemes like http
, data
, or https
. (I'm assuming that you're not making an actual cross-origin request, i.e the header.html file is actually on the same domain as the page you're requesting it from)
So, if the accepted answer above isn't working for you, please make sure you're running a web server. The quickest and simplest way to do that if you're in a rush (and using a Mac, which has Python pre-installed) would be to spin up a simple Python http server. You can see how easy it is to do that here.
I hope this helps!

You need to add a mapping for the SVC extension to ASP.NET. The easiest way to do this is to run ServiceModelReg.exe -i
from C:\Windows\Microsoft.NET\Framework\v3.0\Windows Communication Foundation. You may also need to enable ASP.NET if you haven't already done so.
If you are using Windows Server 2012 or 2016, follow these instructions instead:
Old thread, but the question is still relevant, so...
(1) The example in your question now DOES work in Firefox. However in addition to calling the event handler (which displays an alert), it ALSO clicks on the link, causing navigation (once the alert is dismissed).
(2) To JUST call the event handler (without triggering navigation) merely replace:
document.getElementById('linkid').click();
with
document.getElementById('linkid').onclick();
Try below for your query. where val is your string or column name.
CASE WHEN PATINDEX('%[a-z]%', REVERSE(val)) > 1
THEN LEFT(val, LEN(val) - PATINDEX('%[a-z]%', REVERSE(val)) + 1)
ELSE '' END
2018 already... I've found this fantastic online tool http://mapshaper.org/ to convert from ESRI shapefiles to SVG, TopoJSON, GeoJSON.
Here is the explanation of how to use it https://www.statsilk.com/maps/convert-esri-shapefile-map-geojson-format
Fast and straightforward! :)
The easiest way is to convert to a date:
SELECT *
FROM dbo.LogRequests
WHERE cast(dateX as date) = '2014-05-09';
Often, such expressions preclude the use of an index. However, according to various sources on the web, the above is sargable (meaning it will use an index), such as this and this.
I would be inclined to use the following, just out of habit:
SELECT *
FROM dbo.LogRequests
WHERE dateX >= '2014-05-09' and dateX < '2014-05-10';
An ultimate way to use jQuery:
Leave the original input field hidden from the screen.
$("#Password").hide(); //Hide it first
var old_id = $("#Password").attr("id"); //Store ID of hidden input for later use
$("#Password").attr("id","Password_hidden"); //Change ID for hidden input
Create new input field on the fly by JavaScript.
var new_input = document.createElement("input");
Migrate the ID and value from hidden input field to the new input field.
new_input.setAttribute("id", old_id); //Assign old hidden input ID to new input
new_input.setAttribute("type","text"); //Set proper type
new_input.value = $("#Password_hidden").val(); //Transfer the value to new input
$("#Password_hidden").after(new_input); //Add new input right behind the hidden input
To get around the error on IE like type property cannot be changed
, you may find this useful as belows:
Attach click/focus/change event to new input element, in order to trigger the same event on hidden input.
$(new_input).click(function(){$("#Password_hidden").click();});
//Replicate above line for all other events like focus, change and so on...
Old hidden input element is still inside the DOM so will react with the event triggered by new input element. As ID is swapped, new input element will act like the old one and respond to any function call to old hidden input's ID, but looks different.
A little bit tricky but WORKS!!! ;-)
Here is a solution without eval nor $() nor `` :
ord () {
local s
printf -v s '\\%03o' $1
printf "$s"
}
ord 65
You don't need --header "Content-Length: $LENGTH".
curl --request POST --data-binary "@template_entry.xml" $URL
Note that GET request does not support content body widely.
Also remember that POST request have 2 different coding schema. This is first form:
$ nc -l -p 6666 & $ curl --request POST --data-binary "@README" http://localhost:6666 POST / HTTP/1.1 User-Agent: curl/7.21.0 (x86_64-pc-linux-gnu) libcurl/7.21.0 OpenSSL/0.9.8o zlib/1.2.3.4 libidn/1.15 libssh2/1.2.6 Host: localhost:6666 Accept: */* Content-Length: 9309 Content-Type: application/x-www-form-urlencoded Expect: 100-continue .. -*- mode: rst; coding: cp1251; fill-column: 80 -*- .. rst2html.py README README.html .. contents::
You probably request this:
-F/--form name=content (HTTP) This lets curl emulate a filled-in form in which a user has pressed the submit button. This causes curl to POST data using the Content- Type multipart/form-data according to RFC2388. This enables uploading of binary files etc. To force the 'content' part to be a file, prefix the file name with an @ sign. To just get the content part from a file, prefix the file name with the symbol <. The difference between @ and < is then that @ makes a file get attached in the post as a file upload, while the < makes a text field and just get the contents for that text field from a file.
if myfile.closed == False:

See my article on understanding vertical alignment. There are multiple techniques to accomplish what you want at the end of the discussion.
(Super-short summary: either set the line-height of the child equal to the height of the container, or set positioning on the container and absolutely position the child at top:50%

I ran into this and realized I didn't fetch the upstream before trying to rebase. All I needed was to git fetch upstream
I use this to either zip or unzip multiple files. The Regex stuff is not required, but I use it to change the date stamp and remove unwanted underscores. I use the empty string in the Compress >> zipPath string to prefix something to all files if required. Also, I usually comment out either Compress() or Decompress() based on what I am doing.
using System;
using System.IO.Compression;
using System.IO;
using System.Text.RegularExpressions;
namespace ZipAndUnzip
{
class Program
{
static void Main(string[] args)
{
var directoryPath = new DirectoryInfo(@"C:\your_path\");
Compress(directoryPath);
Decompress(directoryPath);
}
public static void Compress(DirectoryInfo directoryPath)
{
foreach (DirectoryInfo directory in directoryPath.GetDirectories())
{
var path = directoryPath.FullName;
var newArchiveName = Regex.Replace(directory.Name, "[0-9]{8}", "20130913");
newArchiveName = Regex.Replace(newArchiveName, "[_]+", "_");
string startPath = path + directory.Name;
string zipPath = path + "" + newArchiveName + ".zip";
ZipFile.CreateFromDirectory(startPath, zipPath);
}
}
public static void Decompress(DirectoryInfo directoryPath)
{
foreach (FileInfo file in directoryPath.GetFiles())
{
var path = directoryPath.FullName;
string zipPath = path + file.Name;
string extractPath = Regex.Replace(path + file.Name, ".zip", "");
ZipFile.ExtractToDirectory(zipPath, extractPath);
}
}
}
}
For example folder named new under E: drive
type the command:
e:\cd new
e:\new\attrib *.* -s -h /s /d
and all the files and folders are un-hidden
How about this?
SELECT Value, ReadTime, ReadDate
FROM YOURTABLE
WHERE CAST(ReadDate AS DATETIME) + ReadTime BETWEEN '2010-09-16 17:00:00' AND '2010-09-21 09:00:00'

Amazon has introduced steps functions in AWS lambda in 2016. I think, now it's more convenient to use steps function as it's really easy to use them. You can build a state machine with two lambda functions as:
You can easily do that as below:
Here you can have first state for produces a quote and another to turns into order
{
Comment: "Produce a quote and turns into an order",
StartAt: "ProduceQuote",
States: {
ProduceQuote: {
"Type": Task,
"Resource": "arn:aws:lambda:us-east-1:123456789012:function:ProduceQuote",
"next": TurnsToOrder
}
TurnsToOrder: {
Type: Task,
Resource: "arn:aws:lambda:us-east-1:123456789012:function:ProduceQuote",
end: true
}
}
}
Steps functions makes it really easy to write multiple lambda functions and run in sequence or in parallel. You can get more information about lambda steps functions here: Steps Functions
Another easy flexible approach to display block at center: using native text alignment with line-height
and text-align
.
Solution:
.parent {
line-height: 100vh;
text-align: center;
}
.child {
display: inline-block;
vertical-align: middle;
line-height: 100%;
}
And html sample:
<div class="parent">
<div class="child">My center block</div>
</div>
We make div.parent
fullscreen, and his single child div.child
align as text with display: inline-block
.
Advantages:

The best option is probably to use a lambda expression that closes over the variables you want to display.
However, be careful in this case, especially if you're calling this in a loop. (I mention this since your variable is an "ID", and this is common in this situation.) If you close over the variable in the wrong scope, you can get a bug. For details, see Eric Lippert's post on the subject. This typically requires making a temporary:
foreach(int id in myIdsToCheck)
{
int tempId = id; // Make a temporary here!
Task.Factory.StartNew( () => CheckFiles(tempId, theBlockingCollection),
cancelCheckFile.Token,
TaskCreationOptions.LongRunning,
TaskScheduler.Default);
}
Also, if your code is like the above, you should be careful with using the LongRunning
hint - with the default scheduler, this causes each task to get its own dedicated thread instead of using the ThreadPool. If you're creating many tasks, this is likely to have a negative impact as you won't get the advantages of the ThreadPool. It's typically geared for a single, long running task (hence its name), not something that would be implemented to work on an item of a collection, etc.
Follow as in picture for removing that lint error and adding automatic fix by addin g--fix in package.json
You need to use the event delegation syntax of .on()
here. Change:
$("#add").click(function() {
to
$("#buildyourform").on('click', '#add', function () {
The C++ way would be to use a std::stringstream
object as:
std::stringstream fmt;
fmt << a << " " << b << " > " << c;
The C way would be to use sprintf
.
The C way is difficult to get right since:
Of course, you may want to fall back on the C way if performance is an issue (imagine you are creating fixed-size million little stringstream
objects and then throwing them away).
You can try this one, it works just fine :
` ImageIcon icon = new ImageIcon(".//Ressources//User_50.png");
this.setIconImage(icon.getImage());`
Here's a working example that I'm using to implement an autocomplete variation the populates a jqueryui selector (list), but I don't want it to function exactly like the jqueryui autocomplete which does a drop-down menu.
$("#tagFilter").on("change keyup paste", function() {
var filterText = $("#tagFilter").val();
$("#tags").empty();
$.getJSON("http://localhost/cgi-bin/tags.php?term=" + filterText,
function(data) {
var i;
for (i = 0; i < data.length; i++) {
var tag = data[i].value;
$("#tags").append("<li class=\"tag\">" + tag + "</li>");
}
});
});

I think this is the easiest and shortest solution to running a batch file without opening the DOS window, it can be very distracting when you want to schedule a set of commands to run periodically, so the DOS window keeps popping up, here is your solution. Use a VBS Script to call the batch file ...
Set WshShell = CreateObject("WScript.Shell" )
WshShell.Run chr(34) & "C:\Batch Files\ mycommands.bat" & Chr(34), 0
Set WshShell = Nothing
Copy the lines above to an editor and save the file with .VBS extension. Edit the .BAT file name and path accordingly.
This is a guaranteed way to get it done in Vanilla (or simply Pure) JavaScript:

I think I tried everything mentioned here, and it still didn't work. Turns out it didn't recognize my domain login to the server as being in the Administrators group because it was implicit through my membership in another group ( Developers ) which is a member of the Administrators group.
I added my individual domain\login to the Administrators group explicitly, logged off and then logged back on to the box, and IE admitted me to the Report Manager homepage without requiring me to run IE as administrator.
I have these settings:
-vmargs
...
-Duser.name=...
-XX:PermSize=256m
-XX:MaxPermSize=256m
-Xmn128m
-Xms256m
-Xmx768m
Eclipse randomly crashed before I set the PermSize equal to MaxPermSize.
You have to change column type to varchar
or integer
for indexing.
SIMPLE STEPS TO ADD ANY LIBRARY IN ANDROID STUDIO:

}
I have successfully captured HTTP traffic using Fiddler2 as a proxy, which can be installed on any Windows PC on your network.
I also experienced the same problem. The simplest solution I found out is:
emulator -list-avds
to see available emulator names.emulator -avd name-of-your-device -netdelay none -netspeed full
-dns-server 8.8.8.8
command and press enter.Another simple solution using Regex You should need to use this
using System.Text.RegularExpressions;
and the code is
string var = "Hello3453232wor705Ld";
string mystr = Regex.Replace(var, @"\d", "");
string mynumber = Regex.Replace(var, @"\D", "");
Console.WriteLine(mystr);
Console.WriteLine(mynumber);
Have a look into the start
command. It should do what you're trying to achieve.
Also, you might be able to leave out path to chrome. The following works on Windows 7:
start chrome "site1.com" "site2.com"

The task is like this:
- name: Populate genders
set_fact:
genders: "{{ genders|default({}) | combine( {item.item.name: item.stdout} ) }}"
with_items: "{{ people.results }}"
It loops through each of the dicts (item
) in the people.results
array, each time creating a new dict like {Bob: "male"}
, and combine()
s that new dict in the genders
array, which ends up like:
{
"Bob": "male",
"Thelma": "female"
}
It assumes the keys (the name
in this case) will be unique.
I then realised I actually wanted a list of dictionaries, as it seems much easier to loop through using with_items
:
- name: Populate genders
set_fact:
genders: "{{ genders|default([]) + [ {'name': item.item.name, 'gender': item.stdout} ] }}"
with_items: "{{ people.results }}"
This keeps combining the existing list with a list containing a single dict. We end up with a genders
array like this:
[
{'name': 'Bob', 'gender': 'male'},
{'name': 'Thelma', 'gender': 'female'}
]
I had countless issues doing this but finally came up with a solution that works.
Basically the code below is adding a click handler to the video but ignoring all the clicks on the lower part (0.82 is arbitrary but seems to work on all sizes).
$("video").click(function(e){
// get click position
var clickY = (e.pageY - $(this).offset().top);
var height = parseFloat( $(this).height() );
// avoids interference with controls
if(y > 0.82*height) return;
// toggles play / pause
this.paused ? this.play() : this.pause();
});
remove partition by
and add group by
clause,
SELECT BrandId
,SUM(ICount) totalSum
FROM Table
WHERE DateId = 20130618
GROUP BY BrandId
Unless there is an overwhelming need to create a mess of variable names, I would just use a dictionary, where you can dynamically create the key names and associate a value to each.
a = {}
k = 0
while k < 10:
<dynamically create key>
key = ...
<calculate value>
value = ...
a[key] = value
k += 1
There are also some interesting data structures in the new 'collections' module that might be applicable:
Update: Please see marked answer as a better solution to implement this. The following solution is no longer required.
Converting the json date to this format "mm/dd/yyyy HH:MM:ss"

You can use for loop to untar multiple .tar.gz files to another folder. The following code will take /destination/folder/path as an argument to the script and untar all .tar.gz files present at the current location in /destination/folder/path.
if [ $# -ne 1 ];
then
echo "invalid argument/s"
echo "Usage: ./script-file-name.sh /target/directory"
exit 0
fi
for file in *.tar.gz
do

Restarting the Management Studio worked for me.
you can use sequence slicing syntax i.e
paramdata[:5] # first five records
paramdata[-5:] # last five records
paramdata[:] # all records
sometimes the dataframe might not fit in the screen buffer in which case you are probably better off either printing a small subset or exporting it to something else, plot or (csv again)
When you only need to check for equality, you can also simply use the in
operator to do a membership test in a sequence of accepted elements:
if message.value[0] in ('/', '\\'):
do_stuff()
Or can also insert the statement inside bracket.
SELECT * FROM tablename WHERE NOT (columnA = 'x')
i ran into this problem and below is a different solution. I were export my components as
export default {
MyComponent1,
MyComponent2
}
and I imported like this:
import { MyComponent1, MyComponent2} from '@/index'
export default {
name: 'App',
components: {
MyComponent1,
MyComponent2
},
};
And it gave this error.
Just use export { ... }
don't use export default
No, Java doesn't support user-defined operator overloading. The only aspect of Java which comes close to "custom" operator overloading is the handling of + for strings, which either results in compile-time concatenation of constants or execution-time concatenation using StringBuilder/StringBuffer. You can't define your own operators which act in the same way though.
For a Java-like (and JVM-based) language which does support operator overloading, you could look at Kotlin or Groovy. Alternatively, you might find luck with a Java compiler plugin solution.
In addition to @Emilia Apostolova answer to get the ground truth labels, from
generator = train_datagen.flow_from_directory("train", batch_size=batch_size)
just call
y_true_labels = generator.classes
The best source is probably Apple's official documentation. The specific variable you are looking for is CONFIGURATION.
2016 Answer:
Javascript has this function, so no need for Jquery.
yournumber.toLocaleString("en");
If the variable table
contains invalid characters (like a space) you should add square brackets around the variable.
public DataTable fillDataTable(string table)
{
string query = "SELECT * FROM dstut.dbo.[" + table + "]";
using(SqlConnection sqlConn = new SqlConnection(conSTR))
using(SqlCommand cmd = new SqlCommand(query, sqlConn))
{
sqlConn.Open();
DataTable dt = new DataTable();
dt.Load(cmd.ExecuteReader());
return dt;
}
}
By the way, be very careful with this kind of code because is open to Sql Injection. I hope for you that the table name doesn't come from user input
If you are using Notepad++ editor (like the tag of the question suggests), you can use the great "Find in Files" functionality.
Go to Search → Find in Files (Ctrl+Shift+F for the keyboard addicted) and enter:
Find What = (cat|town)
Filters = *.txt
Directory = enter the path of the directory you want to search in. You can check Follow current doc.
to have the path of the current file to be filled.
Search mode = Regular Expression
Try the following :
String url = "http://www.google.com/search?q=java";
URL urlObj = (URL)new URL(url.trim());
HttpURLConnection httpConn =
(HttpURLConnection)urlObj.openConnection();
httpConn.setRequestMethod("GET");
Integer rescode = httpConn.getResponseCode();
System.out.println(rescode);
Trim() the URL
I haven't timed it but I suspect this would be pretty quick:
import numpy as np
list1=[1, 2, 3]
list2=[4, 5, 6]
list_sum = (np.add(list1, list2)).tolist()
[5, 7, 9]

Quick answer
On src, you can always specify files to ignore using "!".
Example (you want to exclude all *.min.js files on your js folder and subfolder:
gulp.src(['js/**/*.js', '!js/**/*.min.js'])
You can do it as well for individual files.
Expanded answer:
Extracted from gulp documentation:
gulp.src(globs[, options])
Emits files matching provided glob or an array of globs. Returns a stream of Vinyl files that can be piped to plugins.
glob refers to node-glob syntax or it can be a direct file path.
So, looking to node-glob documentation we can see that it uses the minimatch library to do its matching.
On minimatch documentation, they point out the following:
if the pattern starts with a ! character, then it is negated.
And that is why using ! symbol will exclude files / directories from a gulp task
DateTime dateTime = DateTime.Now ;
string today = dateTime.DayOfWeek.ToString();
string yesterday = dateTime.AddDays(-1).DayOfWeek.ToString(); //Fetch day i.e. Mon, Tues
string result = dateTime.AddDays(-1).ToString("yyyy-MM-dd");
The above snippet will work. It is also advisable to make single instance of DateTime.Now;
You're looking for UPDATE not insert.
UPDATE mytable
SET table_column = 'test';
UPDATE will change the values of existing rows (and can include a WHERE to make it only affect specific rows), whereas INSERT is adding a new row (which makes it look like it changed only the last row, but in effect is adding a new row with that value).

you can try in this way if you are using thymeleaf
sec:authorize="hasAnyRole(T(com.orsbv.hcs.model.SystemRole).ADMIN.getName(),
T(com.orsbv.hcs.model.SystemRole).SUPER_USER.getName(),'ROLE_MANAGEMENT')"
this will return true if the user has the mentioned roles,false otherwise.
Please note you have to use sec tag in your html declaration tag like this
<html xmlns:sec="http://www.thymeleaf.org/thymeleaf-extras-springsecurity4">
Regarding [Console]::WriteLine() - you should use it if you are going to use pipelines in CMD (not in powershell). Say you want your ps1 to stream a lot of data to stdout, and some other utility to consume/transform it. If you use Write-Host in the script it will be much slower.
You code looks like automatically generated from other code - you should check that html elements with id=i1
and i2
and name=username
and password
exists before processing them.
In the format of unutbu's answer; I made a utility module that handles things like this, with more intuitive syntax. Can be installed with pip.
import datetime
import saturn
unaware = datetime.datetime(2011, 8, 15, 8, 15, 12, 0)
now_aware = saturn.fix_naive(unaware)
now_aware_madrid = saturn.fix_naive(unaware, 'Europe/Madrid')
The Chapter object should have reference to the book it came from so I would suggest something like chapter.getBook().getTitle();
Your database table structure should have a books table and a chapters table with columns like:
books
chapters
Then to reduce the number of queries use a join table in your search query.
As of February 2018, installing brew
on Ubuntu (mine is 17.10) machine is as simple as:
sudo apt install linuxbrew-wrapper
Then, on first brew
execution (just type brew --help
) you will be asked for two installation options:
me@computer:~/$ brew --help
==> Select the Linuxbrew installation directory
- Enter your password to install to /home/linuxbrew/.linuxbrew (recommended)
- Press Control-D to install to /home/me/.linuxbrew
- Press Control-C to cancel installation
[sudo] password for me:
For recommended option type your password (if your current user is in sudo
group), or, if you prefer installing all the dependencies in your own home folder, hit Ctrl+D. Enjoy.
Updating directly the item passed as argument should do the job, but I am maybe missing something here ?
updateItem(item){
this.itemService.getUpdate(item.id)
.subscribe(updatedItem => {
item = updatedItem;
});
}
EDIT : If you really have no choice but to loop through your entire array to update your item, use findIndex :
let itemIndex = this.items.findIndex(item => item.id == retrievedItem.id);
this.items[itemIndex] = retrievedItem;
I used withStyles
instead of makeStyle
EX :
import { withStyles } from '@material-ui/core/styles';
import React, {Component} from "react";
const useStyles = theme => ({
root: {
flexGrow: 1,
},
});
class App extends Component {
render() {
const { classes } = this.props;
return(
<div className={classes.root}>
Test
</div>
)
}
}
export default withStyles(useStyles)(App)
You are trying to alter the behaviour of onclick
inside the same function call. Try it like this:
<a id="loginLink" onclick="toggleTable();" href="#">Login</a>
function toggleTable() {
var lTable = document.getElementById("loginTable");
lTable.style.display = (lTable.style.display == "table") ? "none" : "table";
}
I just experienced similiar problem with copy-protection wordpress plugin. The code was:
function disableSelection(target){
if (typeof target.onselectstart!="undefined") //For IE
target.onselectstart=function(){return false}
else if (typeof target.style.MozUserSelect!="undefined") //For Firefox
target.style.MozUserSelect="none"
else //All other route (For Opera)
target.onmousedown=function(){return false}
target.style.cursor = "default"
}
And then it was initiated by loosely put
<script type="text/javascript">disableSelection(document.body)</script>.
I came around this simply by attaching other annonymous function to this event:
document.body.onselectstart = function() { return true; };
As a simple mutable solution you can call splice twice in a row:
playlist.splice(playlist.length - 1, 1, ...playlist.splice(INDEX_TO_MOVE, 1))
On the other hand, a simple inmutable solution could use slice since this method returns a copy of a section from the original array without changing it:
const copy = [...playlist.slice(0, INDEX_TO_MOVE - 1), ...playlist.slice(INDEX_TO_MOVE), ...playlist.slice(INDEX_TO_MOVE - 1, INDEX_TO_MOVE)]
pg_ctl -D /usr/local/var/postgres start
FATAL: could not open directory "pg_tblspc": No such file or directory
.mkdir /usr/local/var/postgres/pg_tblspc
FATAL: lock file "postmaster.pid" already exists
rm /usr/local/var/postgres/postmaster.pid
pg_ctl -D /usr/local/var/postgres start
Windows does not really support dual mode applications.
To see console output you need to create a console application
CONFIG += console
However, if you double click on the program to start the GUI mode version then you will get a console window appearing, which is probably not what you want. To prevent the console window appearing you have to create a GUI mode application in which case you get no output in the console.
One idea may be to create a second small application which is a console application and provides the output. This can call the second one to do the work.
Or you could put all the functionality in a DLL then create two versions of the .exe file which have very simple main functions which call into the DLL. One is for the GUI and one is for the console.
These messages are rather misleading and understandably a source of confusion. Older Ubuntu versions used Libav which is a fork of the FFmpeg project. FFmpeg returned in Ubuntu 15.04 "Vivid Vervet".
The fork was basically a non-amicable result of conflicting personalities and development styles within the FFmpeg community. It is worth noting that the maintainer for Debian/Ubuntu switched from FFmpeg to Libav on his own accord due to being involved with the Libav fork.
ffmpeg
vs the fake oneFor a while both Libav and FFmpeg separately developed their own version of ffmpeg
.
Libav then renamed their bizarro ffmpeg
to avconv
to distance themselves from the FFmpeg project. During the transition period the "not developed anymore" message was displayed to tell users to start using avconv
instead of their counterfeit version of ffmpeg
. This confused users into thinking that FFmpeg (the project) is dead, which is not true. A bad choice of words, but I can't imagine Libav not expecting such a response by general users.
This message was removed upstream when the fake "ffmpeg
" was finally removed from the Libav source, but, depending on your version, it can still show up in Ubuntu because the Libav source Ubuntu uses is from the ffmpeg-to-avconv transition period.
In June 2012, the message was re-worded for the package libav - 4:0.8.3-0ubuntu0.12.04.1
. Unfortunately the new "deprecated" message has caused additional user confusion.
Starting with Ubuntu 15.04 "Vivid Vervet", FFmpeg's ffmpeg
is back in the repositories again.
To further complicate matters, Libav chose a name that was historically used by FFmpeg to refer to its libraries (libavcodec, libavformat, etc). For example the libav-user mailing list, for questions and discussions about using the FFmpeg libraries, is unrelated to the Libav project.
If you are using avconv
then you are using Libav. If you are using ffmpeg
you could be using FFmpeg or Libav. Refer to the first line in the console output to tell the difference: the copyright notice will either mention FFmpeg or Libav.
Secondly, the version numbering schemes differ. Each of the FFmpeg or Libav libraries contains a version.h
header which shows a version number. FFmpeg will end in three digits, such as 57.67.100, and Libav will end in one digit such as 57.67.0. You can also view the library version numbers by running ffmpeg
or avconv
and viewing the console output.
ffmpeg
The real ffmpeg
is in the repository, so you can install it with:
apt-get install ffmpeg
Your options are:
ffmpeg
,ffmpeg
,These methods are non-intrusive, reversible, and will not interfere with the system or any repository packages.
Another possible option is to upgrade to Ubuntu 15.04 "Vivid Vervet" or newer and just use ffmpeg
from the repository.
For an interesting blog article on the situation, as well as a discussion about the main technical differences between the projects, see The FFmpeg/Libav situation.
As the error information said first please try to increase the timeout value in the both the client side and service side as following:
<basicHttpBinding>
<binding name="basicHttpBinding_ACRMS" maxBufferSize="2147483647"
maxReceivedMessageSize="2147483647"
openTimeout="00:20:00"
receiveTimeout="00:20:00" closeTimeout="00:20:00"
sendTimeout="00:20:00">
<readerQuotas maxDepth="32" maxStringContentLength="2097152"
maxArrayLength="2097152" maxBytesPerRead="4006" maxNameTableCharCount="16384" />
</binding>
Then please do not forget to apply this binding configuration to the endpoint by doing the following:
<endpoint address="" binding="basicHttpBinding"
bindingConfiguration="basicHttpBinding_ACRMS"
contract="MonitorRAM.IService1" />
If the above can not help, it will be better if you can try to upload your main project here, then I want to have a test in my side.
You need to do this in a loop, there is no built-in operation to remove a number of indexes at once.
Your example is actually a contiguous sequence of indexes, so you can do this:
del my_list[2:6]
which removes the slice starting at 2 and ending just before 6.
It isn't clear from your question whether in general you need to remove an arbitrary collection of indexes, or if it will always be a contiguous sequence.
If you have an arbitrary collection of indexes, then:
indexes = [2, 3, 5]
for index in sorted(indexes, reverse=True):
del my_list[index]
Note that you need to delete them in reverse order so that you don't throw off the subsequent indexes.
It might help you!

You cannot supply system properties to the jarsigner.exe tool, unfortunately.
I have submitted defect 7177232, referencing @eckes' defect 7127374 and explaining why it was closed in error.
My defect is specifically about the impact on the jarsigner tool, but perhaps it will lead them to reopening the other defect and addressing the issue properly.
UPDATE: Actually, it turns out that you CAN supply system properties to the Jarsigner tool, it's just not in the help message. Use jarsigner -J-Djsse.enableSNIExtension=false
git pull origin master
this will sync your master to the central repo and if new branches are pushed to the central repo it will also update your clone copy.
I believe you are not the only one who has problems when trying to deploy Crystal Report for VS 2010. Based on the error message you had, have you checked:
Please make sure you just have one CR version installed on your system. If you do have other CR version installed, consider to uninstall it so that your application is not "confused" about the CR version.
You need to make sure you download the correct CR version. Since you are using VS 2010, you need to refer to CRforVS_redist_install_64bit_13_0_1.zip (for 64 bit machine) or CRforVS_redist_install_32bit_13_0_1.zip (for 32 bit machine). These two are the redistributable packages. You can download full package from the below link as well: CRforVS_13_0_1.exe Note: It is sometimes necessary to install 32bit CR runtime even on 64bit OS
Make sure you setup FULL TRUST permission on your root folder
The LOCAL SERVICE permission must be setup on your application pool
Make sure the aspnet_client folder exists on your root folder.
If you can make sure all the 5 points above, your Crystal Report should work without any fuss.
Another important thing to note down here is that if you host your Crystal Report with a shared host, you need to check it with them of whether they really support Crystal Report. If you still have problems, you can switch to http://www.asphostcentral.com, who provides Crystal Report support.
Good luck!
In my case, there is a redundant \

SOLVER.BASE_LR 0.0125 \

Here's what I use to generate random numbers.
function random(high,low) {
high++;
return Math.floor((Math.random())*(high-low))+low;
}
We do execute high++
becauseMath.random()
generates a random number between 0, (inclusive), and 1(exclusive) The one being excluded, means we must increase the high by one before executing any math. We then subtract low from high, giving us the highest number to generate - low, then +low, bringing high back to normal, and making the lowest number atleast low. then we return the resulting number
random(7,3)
could return 3,4,5,6, or 7
You are missing, that \ is the escape character.
Look here: http://docs.python.org/reference/lexical_analysis.html at 2.4.1 "Escape Sequence"
Most importantly \n is a newline character. And \\ is an escaped escape character :D
>>> a = 'a\\\\nb'
>>> a
'a\\\\nb'
>>> print a
a\\nb
>>> a.replace('\\\\', '\\')
'a\\nb'
>>> print a.replace('\\\\', '\\')
a\nb

Bootstrap 3 has an answer for this built in, set your container div in your navbar to container-fluid
and it'll fall to screen width.
Like so:

There is no way to prevent session hijaking 100%, but with some approach can we reduce the time for an attacker to hijaking the session.
Method to prevent session hijaking:
1 - always use session with ssl certificate;
2 - send session cookie only with httponly set to true(prevent javascript to access session cookie)
2 - use session regenerate id at login and logout(note: do not use session regenerate at each request because if you have consecutive ajax request then you have a chance to create multiple session.)
3 - set a session timeout
4 - store browser user agent in a $_SESSION variable an compare with $_SERVER['HTTP_USER_AGENT'] at each request
5 - set a token cookie ,and set expiration time of that cookie to 0(until the browser is closed). Regenerate the cookie value for each request.(For ajax request do not regenerate token cookie). EX:
//set a token cookie if one not exist
if(!isset($_COOKIE['user_token'])){
//generate a random string for cookie value
$cookie_token = bin2hex(mcrypt_create_iv('16' , MCRYPT_DEV_URANDOM));
//set a session variable with that random string
$_SESSION['user_token'] = $cookie_token;
//set cookie with rand value
setcookie('user_token', $cookie_token , 0 , '/' , 'donategame.com' , true , true);
}
//set a sesison variable with request of www.example.com
if(!isset($_SESSION['request'])){
$_SESSION['request'] = -1;
}
//increment $_SESSION['request'] with 1 for each request at www.example.com
$_SESSION['request']++;
//verify if $_SESSION['user_token'] it's equal with $_COOKIE['user_token'] only for $_SESSION['request'] > 0
if($_SESSION['request'] > 0){
// if it's equal then regenerete value of token cookie if not then destroy_session
if($_SESSION['user_token'] === $_COOKIE['user_token']){
$cookie_token = bin2hex(mcrypt_create_iv('16' , MCRYPT_DEV_URANDOM));
$_SESSION['user_token'] = $cookie_token;
setcookie('user_token', $cookie_token , 0 , '/' , 'donategame.com' , true , true);
}else{
//code for session_destroy
}
}
//prevent session hijaking with browser user agent
if(!isset($_SESSION['user_agent'])){
$_SESSION['user_agent'] = $_SERVER['HTTP_USER_AGENT'];
}
if($_SESSION['user_agent'] != $_SERVER['HTTP_USER_AGENT']){
die('session hijaking - user agent');
}
note: do not regenerate token cookie with ajax request note: the code above is an example. note: if users logout then the cookie token must be destroyed as well as the session
6 - it's not a good aproach to use user ip for preventing session hijaking because some users ip change with each request. THAT AFFECT VALID USERS
7 - personally I store session data in database , it's up to you what method you adopt
If you find mistake in my approach please correct me. If you have more ways to prevent session hyjaking please tell me.
You can use the ThenBy and ThenByDescending extension methods:
foobarList.OrderBy(x => x.Foo).ThenBy( x => x.Bar)
You could also use http://download.oracle.com/javase/6/docs/api/java/util/StringTokenizer.html
No, there is no difference, pure syntactic sugar.
According to the documentation NUM_ROWS is the "Number of rows in the table", so I can see how this might be confusing. There, however, is a major difference between these two methods.
This query selects the number of rows in MY_TABLE from a system view. This is data that Oracle has previously collected and stored.
select num_rows from all_tables where table_name = 'MY_TABLE'
This query counts the current number of rows in MY_TABLE
select count(*) from my_table
By definition they are difference pieces of data. There are two additional pieces of information you need about NUM_ROWS.
In the documentation there's an asterisk by the column name, which leads to this note:
Columns marked with an asterisk (*) are populated only if you collect statistics on the table with the ANALYZE statement or the DBMS_STATS package.
This means that unless you have gathered statistics on the table then this column will not have any data.
Statistics gathered in 11g+ with the default estimate_percent
, or with a 100% estimate, will return an accurate number for that point in time. But statistics gathered before 11g, or with a custom estimate_percent
less than 100%, uses dynamic sampling and may be incorrect. If you gather 99.999% a single row may be missed, which in turn means that the answer you get is incorrect.
If your table is never updated then it is certainly possible to use ALL_TABLES.NUM_ROWS to find out the number of rows in a table. However, and it's a big however, if any process inserts or deletes rows from your table it will be at best a good approximation and depending on whether your database gathers statistics automatically could be horribly wrong.
Generally speaking, it is always better to actually count the number of rows in the table rather then relying on the system tables.
Not really sure what you meant by "the caption in the middle", but here's one solution to get your images appear side by side, using the excellent display:inline-block
:

<title></title>
<style>
div.container {
display:inline-block;
}
p {
text-align:center;
}
</style>
</head>
<body>
<div class="container">
<img src="http://placehold.it/350x150" height="200" width="200" />
<p>This is image 1</p>
</div>
<div class="container">

IF you have tables A
and B
, both with colum C
, here are the records, which are present in table A
but not in B
:
SELECT A.*
FROM A
LEFT JOIN B ON (A.C = B.C)
WHERE B.C IS NULL
To get all the differences with a single query, a full join must be used, like this:
SELECT A.*, B.*
FROM A
FULL JOIN B ON (A.C = B.C)
WHERE A.C IS NULL OR B.C IS NULL
What you need to know in this case is, that when a record can be found in A
, but not in B
, than the columns which come from B
will be NULL, and similarly for those, which are present in B
and not in A
, the columns from A
will be null.
If you do not want to allow user to enter text TextView
is the best option here. Any how you can also add EditText
for this purpose. here is a sample code for that.
This would automatically show scrollbar if there is more text than the specified lines.
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:inputType="textMultiLine"
android:lines="8"
android:maxLines="10"
android:minLines="6"
android:scrollbars="vertical" />
Edit: Adding attributes below to textView
would make it a textArea
that would not be editable.
android:lines="8"
android:maxLines="10"
android:minLines="6" // optional
This should work
$root = realpath($_SERVER["DOCUMENT_ROOT"]);
include "$root/inc/include1.php";
Edit: added imporvement by aussieviking
Do not use primitives in your Entity classes, use instead their respective wrappers. That will fix this problem.
Out of your Entity classes you can use the != null validation for the rest of your code flow.
The correct way to apply a filter to a JTable is through the RowFilter interface added to a TableRowSorter. Using this interface, the view of a model can be changed without changing the underlying model. This strategy preserves the Model-View-Controller paradigm, whereas removing the rows you wish hidden from the model itself breaks the paradigm by confusing your separation of concerns.
In c# Option("truncate", false)
does not truncate data in the output.
StreamingQuery query = spark
.Sql("SELECT * FROM Messages")
.WriteStream()
.OutputMode("append")
.Format("console")
.Option("truncate", false)
.Start();
Best approach, no crazed values, distributed with respect to the representable intervals on the floating-point number line (removed "uniform" as with respect to a continuous number line it is decidedly non-uniform):
static float NextFloat(Random random)
{
double mantissa = (random.NextDouble() * 2.0) - 1.0;
// choose -149 instead of -126 to also generate subnormal floats (*)
double exponent = Math.Pow(2.0, random.Next(-126, 128));
return (float)(mantissa * exponent);
}
(*) ... check here for subnormal floats
Warning: generates positive infinity as well! Choose exponent of 127 to be on the safe side.
Another approach which will give you some crazed values (uniform distribution of bit patterns), potentially useful for fuzzing:
static float NextFloat(Random random)
{
var buffer = new byte[4];
random.NextBytes(buffer);
return BitConverter.ToSingle(buffer,0);
}
An improvement over the previous version is this one, which does not create "crazed" values (neither infinities nor NaN) and is still fast (also distributed with respect to the representable intervals on the floating-point number line):
public static float Generate(Random prng)
{
var sign = prng.Next(2);
var exponent = prng.Next((1 << 8) - 1); // do not generate 0xFF (infinities and NaN)
var mantissa = prng.Next(1 << 23);
var bits = (sign << 31) + (exponent << 23) + mantissa;
return IntBitsToFloat(bits);
}
private static float IntBitsToFloat(int bits)
{
unsafe
{
return *(float*) &bits;
}
}
Least useful approach:
static float NextFloat(Random random)
{
// Not a uniform distribution w.r.t. the binary floating-point number line
// which makes sense given that NextDouble is uniform from 0.0 to 1.0.
// Uniform w.r.t. a continuous number line.
//
// The range produced by this method is 6.8e38.
//
// Therefore if NextDouble produces values in the range of 0.0 to 0.1
// 10% of the time, we will only produce numbers less than 1e38 about
// 10% of the time, which does not make sense.
var result = (random.NextDouble()
* (Single.MaxValue - (double)Single.MinValue))
+ Single.MinValue;
return (float)result;
}
Floating point number line from: Intel Architecture Software Developer's Manual Volume 1: Basic Architecture. The Y-axis is logarithmic (base-2) because consecutive binary floating point numbers do not differ linearly.
You need to escape your backslash by preceding it with, yes, another backslash:
print("\\")
And for versions prior to Python 3:
print "\\"
The \
character is called an escape character, which interprets the character following it differently. For example, n
by itself is simply a letter, but when you precede it with a backslash, it becomes \n
, which is the newline character.
As you can probably guess, \
also needs to be escaped so it doesn't function like an escape character. You have to... escape the escape, essentially.

Thanks Darin, For me, to be able to post to the create method, It only worked after I modified the BindModel code to :
public override object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext)
{
var displayFormat = bindingContext.ModelMetadata.DisplayFormatString;
var value = bindingContext.ValueProvider.GetValue(bindingContext.ModelName);
if (!string.IsNullOrEmpty(displayFormat) && value != null)
{
DateTime date;
displayFormat = displayFormat.Replace("{0:", string.Empty).Replace("}", string.Empty);
// use the format specified in the DisplayFormat attribute to parse the date
if (DateTime.TryParse(value.AttemptedValue, CultureInfo.GetCultureInfo("en-GB"), DateTimeStyles.None, out date))
{
return date;
}
else
{
bindingContext.ModelState.AddModelError(
bindingContext.ModelName,
string.Format("{0} is an invalid date format", value.AttemptedValue)
);
}
}
return base.BindModel(controllerContext, bindingContext);
}
Hope this could help someone else...

The ASCIIfication of 3 is "\x33"
not "\x03"
!
That is what python does for str(3)
but it would be totally wrong for bytes, as they should be considered arrays of binary data and not be abused as strings.
The most easy way to achieve what you want is bytes((3,))
, which is better than bytes([3])
because initializing a list is much more expensive, so never use lists when you can use tuples. You can convert bigger integers by using int.to_bytes(3, "little")
.
Initializing bytes with a given length makes sense and is the most useful, as they are often used to create some type of buffer for which you need some memory of given size allocated. I often use this when initializing arrays or expanding some file by writing zeros to it.
The simplest solution:
<artifactId>Example</artifactId>
<version>1.0</version>
<properties>
<jarName>${project.artifactId}-${project.version}</jarName>
</properties>
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>3.0.2</version>
<configuration>
<finalName>${jarName}</finalName>
</configuration>
</plugin>
</plugins>
</build>
Which results in:
mvn clean package -DjarName=123
-> target/123.jar
mvn clean package
-> target/Example.jar
The idle shortcut is an "Advertised Shortcut" which breaks certain features like the "find target" button. Google for more info.
You can view the link with a hex editor or download LNK Parser to see where it points to.

Regarding C#, in some senses interfaces and abstract classes can be interchangeable. However, the differences are: i) interfaces cannot implement code; ii) because of this, interfaces cannot call further up the stack to subclass; and iii) only can abstract class may be inherited on a class, whereas multiple interfaces may be implemented on a class.
imgtag.group(0)
or imgtag.group()
. This returns the entire match as a string. You are not capturing anything else either.
EDIT: Starting from IPython 3 (now Jupyter project), the notebook has a text editor that can be used as a more convenient alternative to load/edit/save text files.
A text file can be loaded in a notebook cell with the magic command %load
.
If you execute a cell containing:
%load filename.py
the content of filename.py
will be loaded in the next cell. You can edit and execute it as usual.
To save the cell content back into a file add the cell-magic %%writefile filename.py
at the beginning of the cell and run it. Beware that if a file with the same name already exists it will be silently overwritten.
To see the help for any magic command add a ?
: like %load?
or %%writefile?
.
For general help on magic functions type "%magic" For a list of the available magic functions, use %lsmagic. For a description of any of them, type %magic_name?, e.g. '%cd?'.
See also: Magic functions from the official IPython docs.
In objective C variables with no value were equal to 'nil'(it was also possible to use 'nil' values same as 0 and false), hence it was possible to use variables in conditional statements (Variables having values are same as 'TRUE' and those with no values were equal to 'FALSE').
Swift provides type safety by providing 'optional value'. i.e. It prevents errors formed from assigning variables of different types.
So in Swift, only booleans can be provided on conditional statements.
var hw = "Hello World"
Here, even-though 'hw' is a string, it can't be used in an if statement like in objective C.
//This is an error
if hw
{..}
For that it needs to be created as,
var nhw : String? = "Hello World"
//This is correct
if nhw
{..}
It shouldn't be HTTP headers if the file has been downloaded successfully and it's the same file that you can open from OI.
A shot in the dark, but could it be that you are not allowing installation from unknown sources, and that OI is somehow bypassing that?

You need to call setHasOptionsMenu(true)
in onCreate()
.
For backwards compatibility it's better to place this call as late as possible at the end of onCreate()
or even later in onActivityCreated()
or something like that.

float: left
… Below are the most common ways to achieve two elements side-by-side…
Some basic css styles for parent
and child
elements in these examples:
.parent {
background: mediumpurple;
padding: 1rem;
}
.child {
border: 1px solid indigo;
padding: 1rem;
}
Using the float
solution my have unintended affect on other elements. (Hint: You may need to use a clearfix.)
html
<div class='parent'>
<div class='child float-left-child'>A</div>
<div class='child float-left-child'>B</div>
</div>
css
.float-left-child {
float: left;
}
html
<div class='parent'>
<div class='child inline-block-child'>A</div>
<div class='child inline-block-child'>B</div>
</div>
css
.inline-block-child {
display: inline-block;
}
Note: the space between these two child elements can be removed, by removing the space between the div tags:
html
<div class='parent'>
<div class='child inline-block-child'>A</div><div class='child inline-block-child'>B</div>
</div>
css
.inline-block-child {
display: inline-block;
}
html
<div class='parent flex-parent'>
<div class='child flex-child'>A</div>
<div class='child flex-child'>B</div>
</div>
css
.flex-parent {
display: flex;
}
.flex-child {
flex: 1;
}
html
<div class='parent inline-flex-parent'>
<div class='child'>A</div>
<div class='child'>B</div>
</div>
css
.inline-flex-parent {
display: inline-flex;
}
html
<div class='parent grid-parent'>
<div class='child'>A</div>
<div class='child'>B</div>
</div>
css
.grid-parent {
display: grid;

Using the browser's parser is the probably the best bet in current browsers. The following will work, with the following caveats:
<div>
element. HTML contained within <body>
or <html>
or <head>
tags is not valid within a <div>
and may therefore not be parsed correctly.textContent
(the DOM standard property) and innerText
(non-standard) properties are not identical. For example, textContent
will include text within a <script>
element while innerText
will not (in most browsers). This only affects IE <=8, which is the only major browser not to support textContent
.<script>
elements.null
<img onerror='alert(\"could run arbitrary JS here\")' src=bogus>
Code:
var html = "<p>Some HTML</p>";
var div = document.createElement("div");
div.innerHTML = html;
var text = div.textContent || div.innerText || "";
One approach would be to put the shared classes/resources in a separate class library project and refer them in both the web sites.
1st of all, when you declare a variable in java, you should declare it using Interfaces even if you specify the implementation when instantiating it
ArrayList<ArrayList<String>> listOfLists = new ArrayList<ArrayList<String>>();
should be written
List<List<String>> listOfLists = new ArrayList<List<String>>(size);
Then you will have to instantiate all columns of your 2d array
for(int i = 0; i < size; i++) {
listOfLists.add(new ArrayList<String>());
}
And you will use it like this :
listOfLists.get(0).add("foobar");
But if you really want to "create a 2D array that each cell is an ArrayList!"
Then you must go the dijkstra way.
No, you can't do this using Javascript alone. Client-side Javascript cannot read the contents of a directory the way I think you're asking about.
However, if you're able to add an index page to (or configure your web server to show an index page for) the images directory and you're serving the Javascript from the same server then you could make an AJAX call to fetch the index and then parse it.
i.e.
1) Enable indexes in Apache for the relevant directory on yoursite.com:
http://www.cyberciti.biz/faq/enabling-apache-file-directory-indexing/
2) Then fetch / parse it with jQuery. You'll have to work out how best to scrape the page and there's almost certainly a more efficient way of fetching the entire list, but an example:
$.ajax({
url: "http://yoursite.com/images/",
success: function(data){
$(data).find("td > a").each(function(){
// will loop through
alert("Found a file: " + $(this).attr("href"));
});
}
});
f = open("Path/To/Your/File.txt", "w") # 'r' for reading and 'w' for writing
f.write("Hello World from " + f.name) # Write inside file
f.close() # Close file
# Method 2shush
with open("Path/To/Your/File.txt", "w") as f: # Opens file and casts as f
f.write("Hello World form " + f.name) # Writing
# File closed automatically
Create Navigation drawer in your MainActivity using fragment.
Initialize the Navigation Drawer in MainActivity
now in all other activities you want to use same Navigation Drawer put DrawerLayout as base and fragment as navigation drawer. Just set android:name in your fragment pointing to your fragment Java file. You won't need to initialize the fragment in other Activities.

So, simplejson.loads takes a json string and returns a data structure, which is why you are getting that type error there.
simplejson.dumps(data) comes back with
'[["apple", "cat"], ["banana", "dog"], ["pear", "fish"]]'
Which is a json array, which is what you want, since you gave this a python array.
If you want to get an "object" type syntax you would instead do
>>> data2 = {'apple':'cat', 'banana':'dog', 'pear':'fish'}
>>> simplejson.dumps(data2)
'{"pear": "fish", "apple": "cat", "banana": "dog"}'
which is javascript will come out as an object.
I hope this would help someone who has the same problem.

flightids array will have another arrays like this [ [ true, 'id_1'], [ false, 'id_2'], [ true, 'id_3']...] here true means user checked it, false means user checked then unchecked it. The items that user have never checked will not be inserted to the array.
flightids = [];

//console.log(this.flightids);
let confirmList = [];
this.flightids.forEach(id => {

In the current version of Google Play store Console as of(August 2017) here is the procedure of unpublishing your app.
After clicking unpublish a dialog will popup confirm and save the changes.
I would suggest static class with static readonly. Please find the code snippet below:
public static class CachedKeysManager
{
public static readonly string DistributorList = "distributorList";
}
Yes, it is security issue. Check folder permissions and service account under which SQL server 2008 starts.
You can go from String (hex)
to byte array
to String as UTF-8(?)
. Make sure your hex string does not have leading spaces and stuff.
public static byte[] hexStringToByteArray(String hex) {
int l = hex.length();
byte[] data = new byte[l / 2];
for (int i = 0; i < l; i += 2) {
data[i / 2] = (byte) ((Character.digit(hex.charAt(i), 16) << 4)
+ Character.digit(hex.charAt(i + 1), 16));
}
return data;
}
Usage:
String b = "0xfd00000aa8660b5b010006acdc0100000101000100010000";
byte[] bytes = hexStringToByteArray(b);
String st = new String(bytes, StandardCharsets.UTF_8);
System.out.println(st);

Your issue is with attempting to change your month by adding 1. 1 in date serials in Excel is equal to 1 day. Try changing your month by using the following:
NewDate = Format(DateAdd("m",1,StartDate),"dd/mm/yyyy")
You would probably use your example like this
var newText = "<span>" + $("p").text().split(" ").join("</span> <span>") + "</span>";
This will put span tags around all the words in you paragraphs, turning
<p>Test is a demo.</p>
into
<p><span>Test</span> <span>is</span> <span>a</span> <span>demo.</span></p>
I do not know what the practical use of this could be.
plt.errorbar
can be used to plot x, y, error data (as opposed to the usual plt.plot
)
import matplotlib.pyplot as plt
import numpy as np
x = np.array([1, 2, 3, 4, 5])
y = np.power(x, 2) # Effectively y = x**2
e = np.array([1.5, 2.6, 3.7, 4.6, 5.5])
plt.errorbar(x, y, e, linestyle='None', marker='^')
plt.show()
plt.errorbar
accepts the same arguments as plt.plot
with additional yerr
and xerr
which default to None (i.e. if you leave them blank it will act as plt.plot
).
OK, first of all I'm not sure how it works when you create a div using (document.createElement('div'))
, so I might be wrong now, but wouldn't it be possible to use the :target pseudo class selector for this?
If you look at the code below, you can se I've used a link to target the div, but in your case it might be possible to target #new from the script instead and that way make the div fade in without user interaction, or am I thinking wrong?
Here's the code for my example:
HTML
<a href="#new">Click</a>
<div id="new">
Fade in ...
</div>
CSS
#new {
width: 100px;
height: 100px;
border: 1px solid #000000;
opacity: 0;
}
#new:target {
-webkit-transition: opacity 2.0s ease-in;
-moz-transition: opacity 2.0s ease-in;
-o-transition: opacity 2.0s ease-in;
opacity: 1;
}
... and here's a jsFiddle
No, but you can in Scala! (And then compile that and run it using any Java implementation!!!!)
Now, if you want to do it the easy way in java, use the Apache commons-lang package. Assuming you're using maven, add this dependency to your pom.xml:
<dependency>
<groupId>commons-lang</groupId>
<artifactId>commons-lang</artifactId>
<version>2.4</version>
</dependency>
And then use StringUtils.repeat as follows:
import org.apache.commons.lang.StringUtils
...
someNum = sumNum + StringUtils.repeat("0", 3);
Starting with the System.IO namespace (particularly the File or FileInfo objects) should get you started.

If you specifically want methods, you should use inspect.ismethod.
For method names:
import inspect
method_names = [attr for attr in dir(self) if inspect.ismethod(getattr(self, attr))]
For the methods themselves:
import inspect
methods = [member for member in [getattr(self, attr) for attr in dir(self)] if inspect.ismethod(member)]
Sometimes inspect.isroutine
can be useful too (for built-ins, C extensions, Cython without the "binding" compiler directive).

Go to res folder and then right click on that folder select the new tab in that go to image asset tab you will get asset studio display page .
Browse(select) the icon that you want get as app icon(no need to change the drawble folder) .
And then click next tab and finish.
Slightly off topic but could be very useful as it could be the basis for other tasks you might want to do with simulators.
I like to keep my simulator list to a minimum, and since there is no multi-select in the "Devices and Simulators" it is a pain to delete them all.
So I boot all the sims that I want to use then, remove all the simulators that I don't have booted.
Delete all the shutdown simulators:
xcrun simctl list | grep -w "Shutdown" | grep -o "([-A-Z0-9]*)" | sed 's/[\(\)]//g' | xargs -I uuid xcrun simctl delete uuid
If you need individual simulators back, just add them back to the list in "Devices and Simulators" with the plus button.

Try the following. It worked for me:
str = str.Split(',').Last();
<div id="calendar"></div>
<script>
$(document).ready(function() {
var days = [];
$('#calendar').datepicker({
dateFormat: 'yymmdd',
showWeek: true, showOtherMonths: false, selectOtherMonths: false,
navigationAsDateFormat: true, prevText: 'MM', nextText: 'MM',
onSelect: function(d) {
var i = $.inArray(d, days);
if (i == -1)
days.push(d);
else
days.splice(i, 1);
},
beforeShowDay: function(d) {
return ([true, $.inArray($.datepicker.formatDate('yymmdd', d), days) == -1 ? 'ui-state-free' : 'ui-state-busy']);
}
});
});
</script>
NOTE: You can prefill days
with a list of dates like '20190101'
with a piece of code in PHP.
Add 2 lines to your CSS:
#calendar .ui-state-busy a {background:#e6e6e6 !important;}
#calendar .ui-state-free a {background:none !important;}
To get the list of days selected by the calendar in a <form>
:
<div id="calendar"></div>
<form method="post">
<input type="submit" name="calendar_get" id="calendar_get" value="Validate" />
</form>
Add this to the <script>
:
$('#calendar_get').click(function() {
$(this).append('<input type="hidden" name="calendar_days" value="' + days.join(',') + '" />');
});
Apply implode
on the string in $_POST['calendar_days']
and map strtotime
to all the formatted dates.
I'm trying to close users connection in version 1.0 and found this method:
socket.conn.close()
The difference between this method and disconnect() is that the client will keep trying to reconnect to the server.
Try for this:
boolean blnResult = Arrays.equals(byteArray1, byteArray2);
I am also not sure about this, but try this may be it works.
You could use euclidean distance from the point highest and nearest the viewer, except that is not quite right. It results in spherical sort order. You can straighten that out by looking from further away. Further away the curvature becomes flattened out. So just add say 1000 to each of the x,y and z components to give x',y' and z'. The sort on x'*x'+y'*y'+z'*z'.
A jQuery solution would be something like:
$(function () {
$('input').blur();
});
It's worked fine in server

OR in Kepler follow as shown below :
You can use
app:cardBackgroundColor="@color/red"
or
android:backgroundTint="@color/red"
You get the error because if
can only evaluate a logical
vector of length 1.
Maybe you miss the difference between &
(|
) and &&
(||
). The shorter version works element-wise and the longer version uses only the first element of each vector, e.g.:
c(TRUE, TRUE) & c(TRUE, FALSE)
# [1] TRUE FALSE
# c(TRUE, TRUE) && c(TRUE, FALSE)
[1] TRUE
You don't need the if
statement at all:
mut1 <- trip$Ref.y=='G' & trip$Variant.y=='T'|trip$Ref.y=='C' & trip$Variant.y=='A'
trip[mut1, "mutType"] <- "G:C to T:A"
Try this RegEx: Matching special charecters which we use in paragraphs and alphabets
Javascript : /^[a-zA-Z]+(([\'\,\.\-_ \/)(:][a-zA-Z_ ])?[a-zA-Z_ .]*)*$/.test(str)
.test(str) returns boolean value if matched true and not matched false
c# : ^[a-zA-Z]+(([\'\,\.\-_ \/)(:][a-zA-Z_ ])?[a-zA-Z_ .]*)*$
Try this:
NSDictionary *textAttributes = [NSDictionary dictionaryWithObjectsAndKeys:
[UIColor whiteColor],NSForegroundColorAttributeName,
[UIColor whiteColor],NSBackgroundColorAttributeName,nil];
self.navigationController.navigationBar.titleTextAttributes = textAttributes;
Not saying this is better, just another way:

I'm adding this answer not because it's likely to be helpful but just because it's true.
In addition to using the existing answers explaining how to make more than one translation by chaining them, you can also construct the 4x4 matrix yourself
I grabbed the following image from some random site I found while googling which shows rotational matrices:
Rotation around x axis:
Rotation around y axis:
Rotation around z axis:
I couldn't find a good example of translation, so assuming I remember/understand it right, translation:
[1 0 0 0]
[0 1 0 0]
[0 0 1 0]
[x y z 1]
See more at the Wikipedia article on transformation as well as the Pragamatic CSS3 tutorial which explains it rather well. Another guide I found which explains arbitrary rotation matrices is Egon Rath's notes on matrices
Matrix multiplication works between these 4x4 matrices of course, so to perform a rotation followed by a translation, you make the appropriate rotation matrix and multiply it by the translation matrix.
This can give you a bit more freedom to get it just right, and will also make it pretty much completely impossible for anyone to understand what it's doing, including you in five minutes.
But, you know, it works.
Edit: I just realized that I missed mentioning probably the most important and practical use of this, which is to incrementally create complex 3D transformations via JavaScript, where things will make a bit more sense.
require
loads a file from the $LOAD_PATH
. If you want to require a file relative to the currently executing file instead of from the $LOAD_PATH
, use require_relative
.
The UPDATE
statement is given so that older fields can be updated to new value. If your older values are the same as your new ones, why would you need to update it in any case?
For eg. if your columns a
to g
are already set as 2
to 8
; there would be no need to re-update it.
Alternatively, you can use:
INSERT INTO table (id,a,b,c,d,e,f,g)
VALUES (1,2,3,4,5,6,7,8)
ON DUPLICATE KEY
UPDATE a=a, b=b, c=c, d=d, e=e, f=f, g=g;
To get the id
from LAST_INSERT_ID
; you need to specify the backend app you're using for the same.
For LuaSQL, a conn:getlastautoid()
fetches the value.
This is for anyone that is trying to get a list of all files in a folder and its sub-folders and save it in a text document.
Below is the full code including the “using” statements, “namespace”, “class”, “methods” etc.
I tried commenting as much as possible throughout the code so you could understand what each part is doing.
This will create a text document that contains a list of all files in all folders and sub-folders of any given root folder. After all, what good is a list (like in Console.WriteLine) if you can’t do something with it.
Here I have created a folder on the C drive called “Folder1” and created a folder inside that one called “Folder2”. Next I filled folder2 with a bunch of files, folders and files and folders within those folders.
This example code will get all the files and create a list in a text document and place that text document in Folder1.
Caution: you shouldn’t save the text document to Folder2 (the folder you are reading from), that would be just bad practice. Always save it to another folder.
I hope this helps someone down the line.

For those who just want to track if js was enabled, how about using an ajax routine to store the state? For example, I log all visitors/visits in a set of tables. The JSenabled field can be set to a default of FALSE, and the ajax routine would set it to TRUE, if JS is enabled.
sudo sh -c "truncate -s 0 /var/lib/docker/containers/*/*-json.log"
This link here answers it. Reading file using relative path in python project
Basically using Path
from pathlib
you'll do the following in script.py
from pathlib import Path
path = Path(__file__).parent / "../data_folder/data.csv"
pd.read_csv(path)
As others have stated there is no standard so you should choose one yourself. Here are a couple of things to consider when doing so:
If you are using JavaScript to consume JSON then using the same naming convention for properties in both will provide visual consistency and possibly some opportunities for cleaner code re-use.
A small reason to avoid kebab-case is that the hyphens may clash visually with -
characters that appear in values.

"bank-balance": -10
}
Perhaps:
> data.frame(aname=NA, bname=NA)[numeric(0), ]
[1] aname bname
<0 rows> (or 0-length row.names)
You could use a regular expression like this
If Regex.IsMatch(number, "^[0-9 ]+$") Then

If you're making a dictionary only to make a list of tuples, as creating dicts like you are may be a pain, you might look into using zip()
Its especialy useful if you've got one heading, and multiple rows. For instance if I assume that you want Olympics stats for countries:
headers = ['Capital', 'Food', 'Year']
countries = [
['London', 'Fish & Chips', '2012'],
['Beijing', 'Noodles', '2008'],
]
for olympics in countries:
print zip(headers, olympics)
gives
[('Capital', 'London'), ('Food', 'Fish & Chips'), ('Year', '2012')]
[('Capital', 'Beijing'), ('Food', 'Noodles'), ('Year', '2008')]
Don't know if thats the end goal, and my be off topic, but it could be something to keep in mind.
Mads Hansen's solution is good but to succeed in reading the external file in .NET 4 took some time to figure out using hints in the comments about resolvers, ProhibitDTD and so on.
This is how it's done:
XmlReaderSettings settings = new XmlReaderSettings();
settings.DtdProcessing = DtdProcessing.Parse;
XmlUrlResolver resolver = new XmlUrlResolver();
resolver.Credentials = System.Net.CredentialCache.DefaultCredentials;
settings.XmlResolver = resolver;
var reader = XmlReader.Create("logfile.xml", settings);
XmlDocument doc = new XmlDocument();
doc.Load(reader);
foreach (XmlElement element in doc.SelectNodes("//event"))
{
var ch = element.ChildNodes;
var count = ch.Count;
}
logfile.xml:
<?xml version="1.0"?>
<!DOCTYPE logfile [
<!ENTITY events
SYSTEM "events.txt">
]>
<logfile>
&events;
</logfile>
events.txt:
<event>
<item1>item1</item1>
<item2>item2</item2>
</event>
In most cases simply switching the virtual machine network adapter to bridged mode is enough to make the guest machine accessible from outside.
Sometimes it's possible for the guest machine to not automatically receive an IP which matches the host's IP range after switching to bridged mode (even after rebooting the guest machine). This is often caused by a malfunctioning or badly configured DHCP on the host network.
For example, if the host IP is 192.168.1.1
the guest machine needs to have an IP in the format 192.168.1.*
where only the last group of numbers is allowed to be different from the host IP.
You can use a terminal (shell) and type ifconfig
(ipconfig
for Windows guests) to check what IP is assigned to the guest machine and change it if required.
If the host and guest IPs do not match simply setting a static IP for the guest machine explicitly should resolve the issue.
I m not satisfied by the best answer by the Joseph, instead of fixing the correct problem, he told that this is wrong use case. In fact there are many places for example if you are converting an old codebase to ajaxified code and there you NEED it, then you NEED it. In programming there is no excuse because its not only you who is coding its all bad and good developers and you have to work side by side. So if I don't code redirection in ajax my fellow developer can force me to have a solution for it. Just like I like to use all AMD patterned sites or mvc4, and my company can keep me away from it for a year.
So let's talk on the solution now.
I have done hell heck of ajax request and response handling and the simplest way I found out was to send status codes to the client and have one standard javascript function to understand those codes. If i simply send for example code 13 it might meant a redirect.
So a json response like { statusCode: 13, messsage: '/home/logged-in' } of course there are tons of variations proposed like { status: 'success', code: 13, url: '/home/logged-in', message: 'You are logged in now' }
etc , so up to your own choice of standard messages
Usually I Inherit from base Controller class and put my choice of standard responses like this
public JsonResult JsonDataResult(object data, string optionalMessage = "")
{
return Json(new { data = data, status = "success", message = optionalMessage }, JsonRequestBehavior.AllowGet);
}
public JsonResult JsonSuccessResult(string message)
{
return Json(new { data = "", status = "success", message = message }, JsonRequestBehavior.AllowGet);
}
public JsonResult JsonErrorResult(string message)
{
return Json(new { data = "", status = "error", message = message }, JsonRequestBehavior.AllowGet);
}
public JsonResult JsonRawResult(object data)
{
return Json(data, JsonRequestBehavior.AllowGet);
}
About using $.ajax intead of Ajax.BeginForm I would love to use Jquery ajax and I do, but again its not me in the whole world to make decisions I have an application full of Ajax.BeginForm and of course I didnt do that. But i have to live with it.
So There is a success callback in begin form too, you don't need to use jquery ajax to use callbacks Something about it here Ajax.BeginForm, Calls Action, Returns JSON, How do I access JSON object in my OnSuccess JS Function?
Thanks

I have solved mine. Its not an NPM Error its related to proxy behavior.
If you are behind proxy,
MAC
1. Goto System Preference (gears icon on your mac)
2. click your network
3. click advanced
4. click proxy
5. check excludes simple hostnames
6. add this line below (Bypass Proxy Settings...) "localhost, localhost:8080"
refer to the npm echo: "Project is running at http://localhost:8080/"
Windows
1. Goto your browser Proxy Settings (google it)
2. check Bypass local address
3. add this line below "localhost, localhost:8080"
Direct value
should work just fine:
var sv = sel.value;
alert(sv);
The only reason your code might fail is when there is no item selected, then the selectedIndex
returns -1 and the code breaks.
What I do is use a csharp ref keyword. For example:
ref MySubClassType e = ref MyMainClass.MySubClass;
you can then use the shortcut like:
e.property
instead of MyMainClass.MySubClass.property
Say your project is structured this way:
+---MyPythonProject
| +---.gitignore
| +---run.py
| | +---subscripts
| | | +---script_one.py
| | | +---script_two.py
Inside run.py
, you can import scripts one and two by:
from subscripts import script_one as One
from subscripts import script_two as Two
Now, still inside run.py
, you'll be able to call their methods with:
One.method_from_one(param)
Two.method_from_two(other_param)
If you did literally this:
encodeURIComponent('&')
Then the result is %26
, you can test it here. Make sure the string you are encoding is just &
and not &
to begin with...otherwise it is encoding correctly, which is likely the case. If you need a different result for some reason, you can do a .replace(/&/g,'&')
before the encoding.
Use this
WITH tblTemp as
(
SELECT ROW_NUMBER() Over(PARTITION BY Name,Department ORDER BY Name)
As RowNumber,* FROM <table_name>
)
DELETE FROM tblTemp where RowNumber >1
Just a small addition to Nick's answer (which works great !) :
If you want to allow spaces in between letters, for example , you may restrict to enter only letters in full name, but it should allow space as well - just list the space as below with a comma. And in the same way if you need to allow any other specific character:
jQuery.validator.addMethod("lettersonly", function(value, element)
{
return this.optional(element) || /^[a-z," "]+$/i.test(value);
}, "Letters and spaces only please");
jQuery provides several selectors (full list) in order to make the queries you are looking for work. To address your question "In other cases is it possible to use other selectors like "contains, less than, greater than, etc..."." you can also use contains, starts with, and ends with to look at these html5 data attributes. See the full list above in order to see all of your options.
The basic querying has been covered above, and using John Hartsock's answer is going to be the best bet to either get every data-company element, or to get every one except Microsoft (or any other version of :not
).
In order to expand this to the other points you are looking for, we can use several meta selectors. First, if you are going to do multiple queries, it is nice to cache the parent selection.
var group = $('ul[data-group="Companies"]');
Next, we can look for companies in this set who start with G
var google = $('[data-company^="G"]',group);//google
Or perhaps companies which contain the word soft
var microsoft = $('[data-company*="soft"]',group);//microsoft
It is also possible to get elements whose data attribute's ending matches
var facebook = $('[data-company$="book"]',group);//facebook
//stored selector_x000D_
var group = $('ul[data-group="Companies"]');_x000D_
_x000D_
//data-company starts with G_x000D_
var google = $('[data-company^="G"]',group).css('color','green');_x000D_
_x000D_
//data-company contains soft_x000D_
var microsoft = $('[data-company*="soft"]',group).css('color','blue');_x000D_
_x000D_
//data-company ends with book_x000D_
var facebook = $('[data-company$="book"]',group).css('color','pink');
_x000D_
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<ul data-group="Companies">_x000D_
<li data-company="Microsoft">Microsoft</li>_x000D_
<li data-company="Google">Google</li>_x000D_

For others, if clearfix does not solve this for you, add margins to the non-floated sibling that is/are the same as the width(s) of the floated sibling(s).
DataTable dt = new DataTable();
SqlDataAdapter adapter = new SqlDataAdapter(cmd);
adapter.Fill(dt);
foreach(DataRow row in dt.Rows)
{
TextBox1.Text = row["ImagePath"].ToString();
}
...assumes the connection is open and the command is set up properly. I also didn't check the syntax, but it should give you the idea.
You can't just change the delimiters from ---- BEGIN SSH2 PUBLIC KEY ----
to -----BEGIN RSA PUBLIC KEY-----
and expect that it will be sufficient to convert from one format to another (which is what you've done in your example).
This article has a good explanation about both formats.
What you get in an RSA PUBLIC KEY
is closer to the content of a PUBLIC KEY
, but you need to offset the start of your ASN.1 structure to reflect the fact that PUBLIC KEY
also has an indicator saying which type of key it is (see RFC 3447). You can see this using openssl asn1parse
and -strparse 19
, as described in this answer.
EDIT: Following your edit, your can get the details of your RSA PUBLIC KEY
structure using grep -v -- ----- | tr -d '\n' | base64 -d | openssl asn1parse -inform DER
:

To decode the SSH key format, you need to use the data format specification in RFC 4251 too, in conjunction with RFC 4253:
The "ssh-rsa" key format has the following specific encoding: string "ssh-rsa" mpint e mpint n
For example, at the beginning, you get 00 00 00 07 73 73 68 2d 72 73 61
. The first four bytes (00 00 00 07
) give you the length. The rest is the string itself: 73=s, 68=h, ... -> 73 73 68 2d 72 73 61
=ssh-rsa
, followed by the exponent of length 1 (00 00 00 01 25
) and the modulus of length 256 (00 00 01 00 7f ...
).
