console.log($(this).val())
});?
.val()
will get the value.
The python seaborn module is based on matplotlib, and produces a very nice heatmap.
Below is an implementation with seaborn, designed for the ipython/jupyter notebook.
import pandas as pd
import matplotlib.pyplot as plt
import seaborn as sns
%matplotlib inline
# import the data directly into a pandas dataframe
nba = pd.read_csv("http://datasets.flowingdata.com/ppg2008.csv", index_col='Name ')
# remove index title
nba.index.name = ""
# normalize data columns
nba_norm = (nba - nba.mean()) / (nba.max() - nba.min())
# relabel columns
labels = ['Games', 'Minutes', 'Points', 'Field goals made', 'Field goal attempts', 'Field goal percentage', 'Free throws made',
'Free throws attempts', 'Free throws percentage','Three-pointers made', 'Three-point attempt', 'Three-point percentage',
'Offensive rebounds', 'Defensive rebounds', 'Total rebounds', 'Assists', 'Steals', 'Blocks', 'Turnover', 'Personal foul']
nba_norm.columns = labels
# set appropriate font and dpi
sns.set(font_scale=1.2)
sns.set_style({"savefig.dpi": 100})
# plot it out
ax = sns.heatmap(nba_norm, cmap=plt.cm.Blues, linewidths=.1)
# set the x-axis labels on the top
ax.xaxis.tick_top()
# rotate the x-axis labels
plt.xticks(rotation=90)
# get figure (usually obtained via "fig,ax=plt.subplots()" with matplotlib)
fig = ax.get_figure()
# specify dimensions and save
fig.set_size_inches(15, 20)
fig.savefig("nba.png")
The output looks like this:
I used the matplotlib Blues color map, but personally find the default colors quite beautiful. I used matplotlib to rotate the x-axis labels, as I couldn't find the seaborn syntax. As noted by grexor, it was necessary to specify the dimensions (fig.set_size_inches) by trial and error, which I found a bit frustrating.
As noted by Paul H, you can easily add the values to heat maps (annot=True), but in this case I didn't think it improved the figure. Several code snippets were taken from the excellent answer by joelotz.
defaultdict
means that if a key is not found in the dictionary, then instead of a KeyError
being thrown, a new entry is created. The type of this new entry is given by the argument of defaultdict.
For example:
somedict = {}
print(somedict[3]) # KeyError
someddict = defaultdict(int)
print(someddict[3]) # print int(), thus 0
Something along the lines of this?
<asp:TextBox id="txtUsername" runat="server" />
<asp:RegularExpressionValidator
id="RegularExpressionValidator1"
runat="server"
ErrorMessage="Field not valid!"
ControlToValidate="txtUsername"
ValidationExpression="[0-9a-zA-Z]{6,}" />
You can try this solution, since onkeypress will be attached directly to the DOM element and will prevent users from entering invalid data to begin with.
So no side-effects on react side.
<input type="text" onKeyPress={onNumberOnlyChange}/>
const onNumberOnlyChange = (event: any) => {
const keyCode = event.keyCode || event.which;
const keyValue = String.fromCharCode(keyCode);
const isValid = new RegExp("[0-9]").test(keyValue);
if (!isValid) {
event.preventDefault();
return;
}
};
Another way to do it simpler using jquery.
sample:
function add(product_id){
// the code to add the product
//updating the div, here I just change the text inside the div.
//You can do anything with jquery, like change style, border etc.
$("#added_"+product_id).html('the product was added to list');
}
Where product_id is the javascript var and$("#added_"+product_id) is a div id concatenated with product_id, the var from function add.
Best Regards!
You can also create a application.properties file in src/test/resources where your JUnits are written.
inside class,
final usernameController = TextEditingController(text: 'bhanuka');
TextField,
child: new TextField(
controller: usernameController,
...
)
The first method is right.
The second method kills kittens if you attempt to do anything with x
after the fact other than Object
methods.
Support for stored procedures in EF Core 1.0 is resolved now, this also supports the mapping of multiple result-sets.

And you can call it like this in c#
var userType = dbContext.Set().FromSql("dbo.SomeSproc @Id = {0}, @Name = {1}", 45, "Ada");
Test with this in trackingCode.html:
<script type="text/javascript">
$(function() {
show_alert();
function show_alert() {
alert("Inside the jQuery ready");
}
});
</script>
The answer by Jones Agyemang is probably sufficient for most use cases and was a great starting point for my solution. For scripting in Git Bent, the git wrapper library I made, I needed something a bit more robust. I'm posting the prototype I've written which is not yet totally script-friendly
<<<<<<< HEAD
which doesn't work for merge conflicts from using git stash apply
which has <<<<<<< Updated Upstream

& >>>>>>>
You need the str_split_line
function from below.
# Root git directory
dir="$(git rev-parse --show-toplevel)"
# Put the grep output into an array (see below)
str_split_line "$(grep -r "^<<<<<<< " "${dir})" files
bn="$(basename "${dir}")"
for i in "${files[@]}"; do
# Remove the matched string, so we're left with the file name
file="$(sed -e "s/:<<<<<<< .*//" <<< "${i}")"
# Remove the path, keep the project dir's name
fileShort="${file#"${dir}"}"
fileShort="${bn}${fileShort}"
# Confirm merge divider & closer are present
c1=$(grep -c "^=======" "${file}")
c2=$(grep -c "^>>>>>>> " "${file}")
if [[ c1 -gt 0 && c2 -gt 0 ]]; then
echo "${fileShort} has a merge conflict"
fi
done
projectdir/file-name
projectdir/subdir/file-name
You can just copy the block of code if you don't want this as a separate function
function str_split_line(){
# for IFS, see https://stackoverflow.com/questions/16831429/when-setting-ifs-to-split-on-newlines-why-is-it-necessary-to-include-a-backspac
IFS="
"
declare -n lines=$2
while read line; do
lines+=("${line}")
done <<< "${1}"
}
Using the type="image"
is problematic because the ability to pass a value is disabled. Although it's not as customizable and thus as pretty, you can still use your images ao long as they are part of a type="button"
.
<button type="submit" name="someName" value="someValue"><img src="someImage.png" alt="SomeAlternateText"></button>
You are comparing a jQuery object (jQuery('input:first')
) to strings (the elements of the array).
Change the code in order to compare the input's value (wich is a string) to the array elements:
if (jQuery.inArray(jQuery("input:first").val(), ar) != -1)
The inArray
method returns -1
if the element wasn't found in the array, so as your bonus answer to how to determine if an element is not in an array, use this :
if(jQuery.inArray(el,arr) == -1){
// the element is not in the array
};
You can create swap space using the following steps
Here we are creating swap at /home/
dd if=/dev/zero of=/home/swapfile1 bs=1024 count=8388608
Here count is kilobyte count of swap space
mkswap /home/swapfile1
vi /etc/fstab
make entry :
/home/swapfile1 swap swap defaults 0 0
run:
swapon -a
Matthew Brindley, your code worked very good for some website I needed (with login), but I needed to change to HttpWebRequest
and HttpWebResponse
otherwise I get a 404 Bad Request from the remote server. Also I would like to share my workaround using your code, and is that I tried it to login to a website based on moodle, but it didn't work at your step "GETting the page behind the login form" because when successfully POSTing the login, the Header 'Set-Cookie'
didn't return anything despite other websites does.
So I think this where we need to store cookies for next Requests, so I added this.
To the "POSTing to the login form" code block :
var cookies = new CookieContainer();
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(formUrl);
req.CookieContainer = cookies;
And To the "GETting the page behind the login form" :
HttpWebRequest getRequest = (HttpWebRequest)WebRequest.Create(getUrl);
getRequest.CookieContainer = new CookieContainer();
getRequest.CookieContainer.Add(resp.Cookies);
getRequest.Headers.Add("Cookie", cookieHeader);
Doing this, lets me Log me in and get the source code of the "page behind login" (website based moodle) I know this is a vague use of the CookieContainer
and HTTPCookies because we may ask first is there a previously set of cookies saved before sending the request to the server. This works without problem anyway, but here's a good info to read about WebRequest
and WebResponse
with sample projects and tutorial:

Think the class should be defined as:
- (void) myTestWithSomeString:(NSString *) astring{
NSLog(@"hi, %s", astring);
}
You only have a single parameter so you should only have a single :
You might want to consider using %@ in your NSLog also - it is just a good habit to get into - will then write out any object - not just strings.

here is my tricky solution how to hide EVERYTHING
Before you start you should realize that all youtube's info are sticks to the top and bottom of iframe(not video, that's important)
Make iframe higher than real video height. In iframe parameters set height = width * 1.7 (or other multiplicator)
Hide youtube's info under your header and footer with an absolute position at top and bottom of iframe wrapper element. Height of header and footer could be calculated as: iframeHeight - (iframeWidth * (9 / 16))) / 2. If you want fullscreen than you should hide it outside screen visible zone and set overflow to hidden
In my case I use JS to destroy iframe after video is finished so user couldn't see youtube's offer with another videos
Also important note: since iOS 12.2 is replacing Youtube's player by their own, width and height calculation should be done in constructor(in case of React) because iOS player arrival cause page resize ->possible width&height recalculation-> video rerender -> video pause
code example jsfiddle.net/s6tp2xfm
A disadvantage of this solution is that it stretches image placeholder.
that's how it could look like with custom controls
You can try that too, for solve timeout problem:
If you didn't add httpRuntime to your webconfig, add that in <system.web>
tag
<sytem.web>
<httpRuntime maxRequestLength="20000" executionTimeout="999999"/>
</system.web>
and
Modify your connection string like this;
<add name="connstring" connectionString="Data Source=DSourceName;Initial Catalog=DBName;Integrated Security=True;Max Pool Size=50000;Pooling=True;" providerName="System.Data.SqlClient" />
At last use
try
{...}
catch
{...}
finaly
{
connection.close();
}
You can use values_list alongside filter like so;
active_emps_first_name = Employees.objects.filter(active=True).values_list('first_name',flat=True)
More details here
IDs must be unique in your document, meaning that you shouldn't do this:
<input type="checkbox" name="chk[]" id="chk[]" value="Apples" />
<input type="checkbox" name="chk[]" id="chk[]" value="Bananas" />
Instead, drop the ID, and then select them by name, or by a containing element:
<fieldset id="checkArray">
<input type="checkbox" name="chk[]" value="Apples" />
<input type="checkbox" name="chk[]" value="Bananas" />
</fieldset>
And now the jQuery:
var atLeastOneIsChecked = $('#checkArray:checkbox:checked').length > 0;
//there should be no space between identifier and selector
// or, without the container:
var atLeastOneIsChecked = $('input[name="chk[]"]:checked').length > 0;
The difference between
import java.util.*;
and
import java.util.*;
import java.util.List;
import java.util.Arrays;
becomes apparent when the code refers to some other List
or Arrays
(for example, in the same package, or also imported generally). In the first case, the compiler will assume that the Arrays
declared in the same package is the one to use, in the latter, since it is declared specifically, the more specific java.util.Arrays
will be used.
I can't comment so here goes. About @David Storey answer.
Be careful on the "order of execution" in CSS3 chains! The order is right to left, not left to right.
transformation: translate(0,10%) rotate(25deg);
The rotate
operation is done first, then the translate
.
See: CSS3 transform order matters: rightmost operation first
Try

What that does is import from the same folder level. If you directly try to import it assumes it's a subordinate
Using ping in C# is achieved by using the method Ping.Send(System.Net.IPAddress)
, which runs a ping request to the provided (valid) IP address or URL and gets a response which is called an Internet Control Message Protocol (ICMP) Packet. The packet contains a header of 20 bytes which contains the response data from the server which received the ping request. The .Net framework System.Net.NetworkInformation
namespace contains a class called PingReply
that has properties designed to translate the ICMP
response and deliver useful information about the pinged server such as:
The following is a simple example using WinForms
to demonstrate how ping works in c#. By providing a valid IP address in textBox1
and clicking button1
, we are creating an instance of the Ping
class, a local variable PingReply
, and a string to store the IP or URL address. We assign PingReply
to the ping Send
method, then we inspect if the request was successful by comparing the status of the reply to the property IPAddress.Success
status. Finally, we extract from PingReply
the information we need to display for the user, which is described above.
using System;
using System.Net.NetworkInformation;
using System.Windows.Forms;
namespace PingTest1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
Ping p = new Ping();
PingReply r;
string s;
s = textBox1.Text;
r = p.Send(s);
if (r.Status == IPStatus.Success)
{
lblResult.Text = "Ping to " + s.ToString() + "[" + r.Address.ToString() + "]" + " Successful"
+ " Response delay = " + r.RoundtripTime.ToString() + " ms" + "\n";
}
}
private void textBox1_Validated(object sender, EventArgs e)
{
if (string.IsNullOrWhiteSpace(textBox1.Text) || textBox1.Text == "")
{
MessageBox.Show("Please use valid IP or web address!!");
}
}
}
}
DATE_ADD
works correctly. 1 January plus 6 months is 1 July, just like 1 January plus 1 month is 1 of February.
Between operation is inclusive. So, you are getting everything up to, and including, 1 July. (see also MySQL "between" clause not inclusive?)
What you need to do is subtract 1 day or use < operator instead of between.
You will also get this exact error if attempting to access your remote/prod db from localhost and you've forgotten that this particular hosting company requires VPN logon in order to access the db (do i feel silly).
You could also use this:
ini_alter('date.timezone','Asia/Calcutta');
You should call this before calling any date function. It accepts the key as the first parameter to alter PHP settings during runtime and the second parameter is the value.
I had done these things before I figured out this:
date_default_timezone_set("Asia/Calcutta");
- did not workini_alter()
- IT WORKEDdate_default_timezone_set("Asia/Calcutta");
- IT WORKEDFor me the init_alter()
method got it all working.

When you click your button you can have it call:
super.onBackPressed();
I generally agree with 5, however, if there is a situation where I need more and it's the clearest way to solve the problem, then I would use more.
You could also do something like this:
SELECT tb1.* FROM Table tb1 WHERE id = (SELECT MAX(tb2.id) FROM Table tb2);
Its useful when you want to make some joins.
After having used Waterboy's code over and over in multiple Python packages, I finally cast it into a tiny standalone Python package, which you can find here:
https://github.com/acschaefer/duallog
The code is well documented and easy to use. Simply download the .py
file and include it in your project, or install the whole package via pip install duallog
.
Use ThisWorkbook
which will refer to the original workbook which holds the code.
Alternatively at code start
Dim Wb As Workbook
Set Wb = ActiveWorkbook
sample code that activates all open books before returning to ThisWorkbook
Sub Test()
Dim Wb As Workbook
Dim Wb2 As Workbook
Set Wb = ThisWorkbook
For Each Wb2 In Application.Workbooks
Wb2.Activate
Next
Wb.Activate
End Sub

I faced the problem in IntelliJ Idea 14 actually. My project was working fine on Android Studio. I decided to continue development on IntelliJ idea. After import of project, I wasn't successful to RUN it and I got similar error message in Edit Configuration box. Based on What @Ali said, I deleted all my SDKs and reinstalled them again but didn't work.
I opened "Project Structure">"Platform Settings">SDKs. I found "Build target" of "Android API 21 Platform" is not set. By set it to one of my latest SDK the problem fixed and I could run project without problem.

The approach that I've taken has evolved since Java 1.0 to provide readability and maintain reasonable options for backward-compatibility with older Java versions, while also providing method signatures that are drop-in replacements for those from apache commons-lang. For performance reasons, I can see some possible objections to the use of Arrays.asList but I prefer helper methods that have sensible defaults without duplicating the one method that performs the actual work. This approach provides appropriate entry points to a reliable method that does not require array/list conversions prior to calling.
Possible variations for Java version compatibility include substituting StringBuffer (Java 1.0) for StringBuilder (Java 1.5), switching out the Java 1.5 iterator and removing the generic wildcard (Java 1.5) from the Collection (Java 1.2). If you want to take backward compatibility a step or two further, delete the methods that use Collection and move the logic into the array-based method.

{
return join(values, ',');

Yes. Use the attach
command. Check out this link for more information. Typing help attach
at a GDB console gives the following:
(gdb) help attach
Attach to a process or file outside of GDB. This command attaches to another target, of the same type as your last "
target
" command ("info files
" will show your target stack). The command may take as argument a process id, a process name (with an optional process-id as a suffix), or a device file. For a process id, you must have permission to send the process a signal, and it must have the same effective uid as the debugger. When using "attach
" to an existing process, the debugger finds the program running in the process, looking first in the current working directory, or (if not found there) using the source file search path (see the "directory
" command). You can also use the "file
" command to specify the program, and to load its symbol table.
NOTE: You may have difficulty attaching to a process due to improved security in the Linux kernel - for example attaching to the child of one shell from another.
You'll likely need to set /proc/sys/kernel/yama/ptrace_scope
depending on your requirements. Many systems now default to 1
or higher.
The sysctl settings (writable only with CAP_SYS_PTRACE) are:
0 - classic ptrace permissions: a process can PTRACE_ATTACH to any other
process running under the same uid, as long as it is dumpable (i.e.
did not transition uids, start privileged, or have called
prctl(PR_SET_DUMPABLE...) already). Similarly, PTRACE_TRACEME is
unchanged.
1 - restricted ptrace: a process must have a predefined relationship
with the inferior it wants to call PTRACE_ATTACH on. By default,
this relationship is that of only its descendants when the above
classic criteria is also met. To change the relationship, an
inferior can call prctl(PR_SET_PTRACER, debugger, ...) to declare
an allowed debugger PID to call PTRACE_ATTACH on the inferior.
Using PTRACE_TRACEME is unchanged.
2 - admin-only attach: only processes with CAP_SYS_PTRACE may use ptrace
with PTRACE_ATTACH, or through children calling PTRACE_TRACEME.
3 - no attach: no processes may use ptrace with PTRACE_ATTACH nor via
PTRACE_TRACEME. Once set, this sysctl value cannot be changed.
Just to be sure that this is really the "conversion" you need, please note that jks
files are keystores, a file format used to store more than one certificate and allows you to retrieve them programmatically using the Java security API, it's not a one-to-one conversion between equivalent formats.
So, if you just want to import that certificate in a new ad-hoc keystore you can do it with Keystore Explorer, a graphical tool. You'll be able to modify the keystore and the certificates contained therein like you would have done with the java terminal utilities like keytool
(but in a more accessible way).

This should work:
string url = "http://example.com/file?a=1&b=2&c=string%20param";
string querystring = url.Substring(url.IndexOf('?'));
System.Collections.Specialized.NameValueCollection parameters =
System.Web.HttpUtility.ParseQueryString(querystring);
According to MSDN. Not the exact collectiontype you are looking for, but nevertheless useful.
Edit: Apparently, if you supply the complete url to ParseQueryString
it will add 'http://example.com/file?a' as the first key of the collection. Since that is probably not what you want, I added the substring to get only the relevant part of the url.
In Java 8 you can do it like this:
import java.util.*;
import java.util.stream.*;
List<JsonNode> datasets = StreamSupport
.stream(datasets.get("datasets").spliterator(), false)
.collect(Collectors.toList())
I always use object, it is more easily extendable, JSON array is not. For example you originally had some data as a json array, then you needed to add a status header on it you'd be a bit stuck, unless you'd nested the data in an object. The only disadvantage is a slight increase in complexity of creation / parsing.
So instead of
[datum0, datum1, datumN]
You'd have
{data: [datum0, datum1, datumN]}
then later you can add more...
{status: "foo", data: [datum0, datum1, datumN]}
There is really no way of "one-lining" what you are trying to do because toArray returns an Object[] and you cannot cast from Object[] to int[] or Integer[] to int[]
The following will parse an XML string into an XML document in all major browsers, including Internet Explorer 6. Once you have that, you can use the usual DOM traversal methods/properties such as childNodes and getElementsByTagName() to get the nodes you want.
var parseXml;

parseXml = function(xmlStr) {
return ( new window.DOMParser() ).parseFromString(xmlStr, "text/xml");
};
} else if (typeof window.ActiveXObject != "undefined" &&
new window.ActiveXObject("Microsoft.XMLDOM")) {
parseXml = function(xmlStr) {
var xmlDoc = new window.ActiveXObject("Microsoft.XMLDOM");
xmlDoc.async = "false";
xmlDoc.loadXML(xmlStr);
return xmlDoc;
};
} else {
throw new Error("No XML parser found");
}
Example usage:

It stores an exact, versioned dependency tree rather than using starred versioning like package.json itself (e.g. 1.0.*). This means you can guarantee the dependencies for other developers or prod releases, etc. It also has a mechanism to lock the tree but generally will regenerate if package.json changes.
From the npm docs:
package-lock.json is automatically generated for any operations where npm modifies either the node_modules tree, or package.json. It describes the exact tree that was generated, such that subsequent installs are able to generate identical trees, regardless of intermediate dependency updates.
This file is intended to be committed into source repositories, and serves various purposes:
Describe a single representation of a dependency tree such that teammates, deployments, and continuous integration are guaranteed to install exactly the same dependencies.
Provide a facility for users to "time-travel" to previous states of node_modules without having to commit the directory itself.
To facilitate greater visibility of tree changes through readable source control diffs.
And optimize the installation process by allowing npm to skip repeated metadata resolutions for previously-installed packages."
To answer jrahhali's question below about just using the package.json with exact version numbers. Bear in mind that your package.json contains only your direct dependencies, not the dependencies of your dependencies (sometimes called nested dependencies). This means with the standard package.json you can't control the versions of those nested dependencies, referencing them directly or as peer dependencies won't help as you also don't control the version tolerance that your direct dependencies define for these nested dependencies.
Even if you lock down the versions of your direct dependencies you cannot 100% guarantee that your full dependency tree will be identical every time. Secondly you might want to allow non-breaking changes (based on semantic versioning) of your direct dependencies which gives you even less control of nested dependencies plus you again can't guarantee that your direct dependencies won't at some point break semantic versioning rules themselves.
The solution to all this is the lock file which as described above locks in the versions of the full dependency tree. This allows you to guarantee your dependency tree for other developers or for releases whilst still allowing testing of new dependency versions (direct or indirect) using your standard package.json.
NB. The previous shrink wrap json did pretty much the same thing but the lock file renames it so that it's function is clearer. If there's already a shrink wrap file in the project then this will be used instead of any lock file.

Every time you start a session (applies to PHP version 5.2.54), session_start()
creates a new session id.
Here is the fix that worked for me.
File1.php
session_id('mySessionID'); //SET id first before calling session start
session_start();
$name = "Nitin Hurkadli";
$_SESSION['username'] = $name;
File2.php
session_id('mySessionID');
session_start();
$name = $_SESSION['username'];
echo "Hello " . $name;
First point, a programming language isn't a "scripting language" or a something else. It can be a "scripting language" and something else.
Second point, the implementer of the language will tell you if it's a scripting language.
Your question should read "In what implementations would a programming language be considered a scripting language?", not "What is the difference between a scripting language and a programming language?". There is no between.
Yet, I will consider a language a scripting language if it is used to provide some type of middle ware. For example, I would consider most implementations of JavaScript a scripting language. If JavaScript were run in the OS, not the browser, then it would not be a scripting language. If PHP runs inside of Apache, it's a scripting language. If it's run from the command line, it's not.
Clearly HttpContext.Current
is not null
only if you access it in a thread that handles incoming requests. That's why it works "when i use this code in another class of a page".
It won't work in the scheduling related class because relevant code is not executed on a valid thread, but a background thread, which has no HTTP context associated with.
Overall, don't use Application["Setting"]
to store global stuffs, as they are not global as you discovered.
If you need to pass certain information down to business logic layer, pass as arguments to the related methods. Don't let your business logic layer access things like HttpContext
or Application["Settings"]
, as that violates the principles of isolation and decoupling.
Update:
Due to the introduction of async/await
it is more often that such issues happen, so you might consider the following tip,
In general, you should only call HttpContext.Current
in only a few scenarios (within an HTTP module for example). In all other cases, you should use
Page.Context
https://docs.microsoft.com/en-us/dotnet/api/system.web.ui.page.context?view=netframework-4.7.2 Controller.HttpContext
https://docs.microsoft.com/en-us/dotnet/api/system.web.mvc.controller.httpcontext?view=aspnet-mvc-5.2instead of HttpContext.Current
.
It says already we are running the services with port no 4200 please use another port instead of 4200. Below command is to solve the problem
ng serve --port 4300
Well, the JVM memory model works something like this: values are stored on one pile of memory stack and objects are stored on another pile of memory called the heap. The garbage collector looks for garbage by looking at a list of objects you've made and seeing which ones aren't pointed at by anything. This is where setting an object to null
comes in; all nonprimitive (think of classes) variables are really references that point to the object on the stack, so by setting the reference you have to null
the garbage collector can see that there's nothing else pointing at the object and it can decide to garbage collect it. All Java objects are stored on the heap so they can be seen and collected by the garbage collector.
Nonprimitive (int
s, char
s, double
s, those sort of things) values, however, aren't stored on the heap. They're created and stored temporarily as they're needed and there's not much you can do there, but thankfully the compilers nowadays are really efficient and will avoid needed to store them on the JVM stack unless they absolutely need to.
On a bytecode level, that's basically how it works. The JVM is based on a stack-based machine, with a couple instructions to create allocate objects on the heap as well, and a ton of instructions to manipulate, push and pop values, off the stack. Local variables are stored on the stack, allocated variables on the heap.* These are the heap and the stack I'm referring to above. Here's a pretty good starting point if you want to get into the nitty gritty details.
In the resulting compiled code, there's a bit of leeway in terms of implementing the heap and stack. Allocation's implemented as allocation, there's really not a way around doing so. Thus the virtual machine heap becomes an actual heap, and allocations in the bytecode are allocations in actual memory. But you can get around using a stack to some extent, since instead of storing the values on a stack (and accessing a ton of memory), you can stored them on registers on the CPU which can be up to a hundred times (maybe even a thousand) faster than storing it on memory. But there's cases where this isn't possible (look up register spilling for one example of when this may happen), and using a stack to implement a stack kind of makes a lot of sense.
And quite frankly in your case a few integers probably won't matter. The compiler will probably optimize them out by itself in this case anyways. Optimization should always happen after you get it running and notice it's a tad slower than you'd prefer it to be. Worry about making simple, elegant, working code first then later make it fast (and hopefully) simple, elegant, working code.
Java's actually very nicely made so that you shouldn't have to worry about null
ing variables very often. Whenever you stop needing to use something, it will usually incidentally be disappearing from the scope of your program (and thus becoming eligible for garbage collection). So I guess the real lesson here is to use local variables as often as you can.
*There's also a constant pool, a local variable pool, and a couple other things in memory but you have close to no control over the size of those things and I want to keep this fairly simple.
This code work as well, instead eval the html i'm going to append the script to the head
function RunJS(objID) {
//alert(http_request.responseText);
var c="";
var ob = document.getElementById(objID).getElementsByTagName("script");
for (var i=0; i < ob.length - 1; i++) {
if (ob[i + 1].text != null)
c+=ob[i + 1].text;
}
var s = document.createElement("script");
s.type = "text/javascript";
s.text = c;
document.getElementsByTagName("head")[0].appendChild(s);

I know this is an old question, but none of the answers worked for me, because I wanted to reliably (always be able to) set the cell into edit mode when possibly executing other events like Toolbar Button clicks, menu selections, etc. that may affect the default focus after those events return. I ended up needing a timer and invoke. The following code is in a new component derived from DataGridView. This code allows me to simply make a call to myXDataGridView.CurrentRow_SelectCellFocus(myDataPropertyName);
anytime I want to arbitrarily set a databound cell to edit mode (assuming the cell is Not in ReadOnly mode).
// If the DGV does not have Focus prior to a toolbar button Click,
// then the toolbar button will have focus after its Click event handler returns.
// To reliably set focus to the DGV, we need to time it to happen After event handler procedure returns.
private string m_SelectCellFocus_DataPropertyName = "";
private System.Timers.Timer timer_CellFocus = null;
public void CurrentRow_SelectCellFocus(string sDataPropertyName)
{
// This procedure is called by a Toolbar Button's Click Event to select and set focus to a Cell in the DGV's Current Row.
m_SelectCellFocus_DataPropertyName = sDataPropertyName;
timer_CellFocus = new System.Timers.Timer(10);
timer_CellFocus.Elapsed += TimerElapsed_CurrentRowSelectCellFocus;
timer_CellFocus.Start();
}
void TimerElapsed_CurrentRowSelectCellFocus(object sender, System.Timers.ElapsedEventArgs e)
{
timer_CellFocus.Stop();
timer_CellFocus.Elapsed -= TimerElapsed_CurrentRowSelectCellFocus;
timer_CellFocus.Dispose();
// We have to Invoke the method to avoid raising a threading error
this.Invoke((MethodInvoker)delegate
{
Select_Cell(m_SelectCellFocus_DataPropertyName);
});
}
private void Select_Cell(string sDataPropertyName)
{
/// When the Edit Mode is Enabled, set the initial cell to the Description
foreach (DataGridViewCell dgvc in this.SelectedCells)
{
// Clear previously selected cells
dgvc.Selected = false;
}
foreach (DataGridViewCell dgvc in this.CurrentRow.Cells)
{
// Select the Cell by its DataPropertyName
if (dgvc.OwningColumn.DataPropertyName == sDataPropertyName)
{
this.CurrentCell = dgvc;
dgvc.Selected = true;
this.Focus();
return;
}
}
}
Assuming you are correct and your id is a proper number (without any other text), you should parse the id and then add one to it:
var currentPage = parseInt($(this).attr('id'), 10);
++currentPage;
doSomething(currentPage);

This error occurred in case of memory leak. For example if you have any static context of an Android component (Activity/service/etc) and its gets killed by system.
Example: Music player controls in notification area. Use a foreground service and set actions in the notification channel via PendingIntent like below.
Intent notificationIntent = new Intent(this, MainActivity.class);
notificationIntent.setAction(AppConstants.ACTION.MAIN_ACTION);
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK
| Intent.FLAG_ACTIVITY_CLEAR_TASK);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0,
notificationIntent, 0);
Intent previousIntent = new Intent(this, ForegroundService.class);
previousIntent.setAction(AppConstants.ACTION.PREV_ACTION);
PendingIntent ppreviousIntent = PendingIntent.getService(this, 0,
previousIntent, 0);
Intent playIntent = new Intent(this, ForegroundService.class);
playIntent.setAction(AppConstants.ACTION.PLAY_ACTION);
PendingIntent pplayIntent = PendingIntent.getService(this, 0,
playIntent, 0);
Intent nextIntent = new Intent(this, ForegroundService.class);
nextIntent.setAction(AppConstants.ACTION.NEXT_ACTION);

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
NotificationChannel notificationChannel = new NotificationChannel(NOTIFICATION_CHANNEL_ID, "My Notifications", NotificationManager.IMPORTANCE_HIGH);
// Configure the notification channel.
notificationChannel.setDescription("Channel description");
notificationChannel.enableLights(true);
notificationChannel.setLightColor(Color.RED);
notificationChannel.setLockscreenVisibility(Notification.VISIBILITY_PRIVATE);
notificationChannel.setVibrationPattern(new long[]{0, 1000, 500, 1000});
notificationChannel.enableVibration(true);
notificationManager.createNotificationChannel(notificationChannel);
}
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this, NOTIFICATION_CHANNEL_ID);
Notification notification = notificationBuilder
.setOngoing(true)
.setAutoCancel(true)
.setWhen(System.currentTimeMillis())
.setContentTitle("Foreground Service")
.setContentText("Foreground Service Running")
.setSmallIcon(R.drawable.ic_launcher)
.setLargeIcon(Bitmap.createScaledBitmap(icon, 128, 128, false))
.setContentIntent(pendingIntent)
.setPriority(NotificationManager.IMPORTANCE_MAX)
.setCategory(Notification.CATEGORY_SERVICE)
.setTicker("Hearty365")
.build();
startForeground(AppConstants.NOTIFICATION_ID.FOREGROUND_SERVICE,
notification);
And if this notification channel get broken abruptly (may be by system, like in Xiomi devices when we clean out the background apps), then due to memory leaks this error is thrown by system.
Before i was running this command
npm install typescript -g
after changing the command it worked perfectly.

The Content-Type
header is just used as info for your application. The browser doesn't care what it is. The browser just returns you the data from the AJAX call. If you want to parse it as JSON, you need to do that on your own.
The header is there so your app can detect what data was returned and how it should handle it. You need to look at the header, and if it's application/json
then parse it as JSON.
This is actually how jQuery works. If you don't tell it what to do with the result, it uses the Content-Type
to detect what to do with it.
this function shows how to create a triangle from bitmap. That is, create triangular shaped cropped image. Try the code below or download demo example
public static Bitmap getTriangleBitmap(Bitmap bitmap, int radius) {
Bitmap finalBitmap;
if (bitmap.getWidth() != radius || bitmap.getHeight() != radius)
finalBitmap = Bitmap.createScaledBitmap(bitmap, radius, radius,
false);
else
finalBitmap = bitmap;
Bitmap output = Bitmap.createBitmap(finalBitmap.getWidth(),
finalBitmap.getHeight(), Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(output);
Paint paint = new Paint();
final Rect rect = new Rect(0, 0, finalBitmap.getWidth(),
finalBitmap.getHeight());
Point point1_draw = new Point(75, 0);
Point point2_draw = new Point(0, 180);
Point point3_draw = new Point(180, 180);
Path path = new Path();
path.moveTo(point1_draw.x, point1_draw.y);
path.lineTo(point2_draw.x, point2_draw.y);
path.lineTo(point3_draw.x, point3_draw.y);
path.lineTo(point1_draw.x, point1_draw.y);
path.close();
canvas.drawARGB(0, 0, 0, 0);
paint.setColor(Color.parseColor("#BAB399"));
canvas.drawPath(path, paint);
paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.SRC_IN));
canvas.drawBitmap(finalBitmap, rect, rect, paint);
return output;
}

Are you sure you want to do this? In essence, you're duplicating the data that is in the three original columns. From that point on, you'll need to make sure that the data in the combined field matches the data in the first three columns. This is more overhead for your application, and other processes that update the system will need to understand the relationship.
If you need the data, why not select in when you need it? The SQL for selecting what would be in that field would be:
SELECT CONCAT(zipcode, ' - ', city, ', ', state) FROM Table;
This way, if the data in the fields changes, you don't have to update your combined field.
From stack trace:
HikariPool: Timeout failure pool HikariPool-0 stats (total=20, active=20, idle=0, waiting=0) Means pool reached maximum connections limit set in configuration.
The next line: HikariPool-0 - Connection is not available, request timed out after 30000ms. Means pool waited 30000ms for free connection but your application not returned any connection meanwhile.
Mostly it is connection leak (connection is not closed after borrowing from pool), set leakDetectionThreshold to the maximum value that you expect SQL query would take to execute.
otherwise, your maximum connections 'at a time' requirement is higher than 20 !
Good explanation and practices about string comparison issues may be found in the article New Recommendations for Using Strings in Microsoft .NET 2.0 and also in Best Practices for Using Strings in the .NET Framework.
Each of mentioned method (and other) has particular purpose. The key difference between them is what sort of StringComparison Enumeration they are using by default. There are several options:
Each of above comparison type targets different use case:
Note, that StringComparison Enumeration as well as overloads for string comparison methods, exists since .NET 2.0.
Is in fact type safe implementation of IComparable.CompareTo Method. Default interpretation: CurrentCulture.
Usage:
The CompareTo method was designed primarily for use in sorting or alphabetizing operations
Thus
Implementing the IComparable interface will necessarily use this method
A static member of String Class which has many overloads. Default interpretation: CurrentCulture.
Whenever possible, you should call an overload of the Compare method that includes a StringComparison parameter.
Overriden from Object class and overloaded for type safety. Default interpretation: Ordinal. Notice that:
The String class's equality methods include the static Equals, the static operator ==, and the instance method Equals.
There is also another way to deal with string comparisons especially aims to sorting:
You can use the StringComparer class to create a type-specific comparison to sort the elements in a generic collection. Classes such as Hashtable, Dictionary, SortedList, and SortedList use the StringComparer class for sorting purposes.
You could do it like this:
HTML
<table>
<tr>
<td>Cell 1</td>
<td>Cell 2</td>
<td>Cell 3</td>
<td>Cell 4</td>
<td><a href="#" id="show_1">Show Extra</a></td>
</tr>
<tr>
<td colspan="5">
<div id="extra_1" style="display: none;">
<br>hidden row
<br>hidden row
<br>hidden row
</div>
</td>
</tr>
</table>
jQuery
$("a[id^=show_]").click(function(event) {
$("#extra_" + $(this).attr('id').substr(5)).slideToggle("slow");
event.preventDefault();
});

Assuming the quotation marks are actually part of the output, couldn't you just use the -o switch to return everything between the quote marks?

.init
/.fini
isn't deprecated. It's still part of the the ELF standard and I'd dare say it will be forever. Code in .init
/.fini
is run by the loader/runtime-linker when code is loaded/unloaded. I.e. on each ELF load (for example a shared library) code in .init
will be run. It's still possible to use that mechanism to achieve about the same thing as with __attribute__((constructor))/((destructor))
. It's old-school but it has some benefits.
.ctors
/.dtors
mechanism for example require support by system-rtl/loader/linker-script. This is far from certain to be available on all systems, for example deeply embedded systems where code executes on bare metal. I.e. even if __attribute__((constructor))/((destructor))
is supported by GCC, it's not certain it will run as it's up to the linker to organize it and to the loader (or in some cases, boot-code) to run it. To use .init
/.fini
instead, the easiest way is to use linker flags: -init & -fini (i.e. from GCC command line, syntax would be -Wl -init my_init -fini my_fini
).
On system supporting both methods, one possible benefit is that code in .init
is run before .ctors
and code in .fini
after .dtors
. If order is relevant that's at least one crude but easy way to distinguish between init/exit functions.
A major drawback is that you can't easily have more than one _init
and one _fini
function per each loadable module and would probably have to fragment code in more .so
than motivated. Another is that when using the linker method described above, one replaces the original _init and _fini
default functions (provided by crti.o
). This is where all sorts of initialization usually occur (on Linux this is where global variable assignment is initialized). A way around that is described here
Notice in the link above that a cascading to the original _init()
is not needed as it's still in place. The call
in the inline assembly however is x86-mnemonic and calling a function from assembly would look completely different for many other architectures (like ARM for example). I.e. code is not transparent.
.init
/.fini
and .ctors
/.detors
mechanisms are similar, but not quite. Code in .init
/.fini
runs "as is". I.e. you can have several functions in .init
/.fini
, but it is AFAIK syntactically difficult to put them there fully transparently in pure C without breaking up code in many small .so
files.
.ctors
/.dtors
are differently organized than .init
/.fini
. .ctors
/.dtors
sections are both just tables with pointers to functions, and the "caller" is a system-provided loop that calls each function indirectly. I.e. the loop-caller can be architecture specific, but as it's part of the system (if it exists at all i.e.) it doesn't matter.
The following snippet adds new function pointers to the .ctors
function array, principally the same way as __attribute__((constructor))
does (method can coexist with __attribute__((constructor)))
.
#define SECTION( S ) __attribute__ ((section ( S )))
void test(void) {
printf("Hello\n");
}
void (*funcptr)(void) SECTION(".ctors") =test;
void (*funcptr2)(void) SECTION(".ctors") =test;
void (*funcptr3)(void) SECTION(".dtors") =test;
One can also add the function pointers to a completely different self-invented section. A modified linker script and an additional function mimicking the loader .ctors
/.dtors
loop is needed in such case. But with it one can achieve better control over execution order, add in-argument and return code handling e.t.a. (In a C++ project for example, it would be useful if in need of something running before or after global constructors).
I'd prefer __attribute__((constructor))/((destructor))
where possible, it's a simple and elegant solution even it feels like cheating. For bare-metal coders like myself, this is just not always an option.

You can install an indentator package.

I have an idea. Why not use the ascii_lowercase
constant?
For example, running the following code:
# string module, contains constant ascii_lowercase which is all the lowercase
# letters of the English alphabet
import string
# Example value of s, a string
s = 'aaabcabccd'
# Result variable to store the resulting string
result = ''
# Goes through each letter in the alphabet and checks how many times it appears.
# If a letter appears at least oce, then it is added to the result variable
for letter in string.ascii_letters:
if s.count(letter) >= 1:
result+=letter
# Optional three lines to convert result variable to a list for sorting
# and then back to a string
result = list(result)
result.sort()
result = ''.join(result)
print(result)
Will print 'abcd'
There you go, all duplicates removed and optionally sorted
If you want something more similar to your example try _itot_s. On Microsoft compilers _itot_s points to _itoa_s or _itow_s depending on your Unicode setting:
CString str;
_itot_s( 15, str.GetBufferSetLength( 40 ), 40, 10 );
str.ReleaseBuffer();
it should be slightly faster since it doesn't need to parse an input format.
You can use segments
to add the bars in base graphics. Here epsilon
controls the line across the top and bottom of the line.
plot (x, y, ylim=c(0, 6))
epsilon = 0.02
for(i in 1:5) {
up = y[i] + sd[i]
low = y[i] - sd[i]
segments(x[i],low , x[i], up)
segments(x[i]-epsilon, up , x[i]+epsilon, up)
segments(x[i]-epsilon, low , x[i]+epsilon, low)
}
As @thelatemail points out, I should really have used vectorised function calls:
segments(x, y-sd,x, y+sd)
epsilon = 0.02
segments(x-epsilon,y-sd,x+epsilon,y-sd)
segments(x-epsilon,y+sd,x+epsilon,y+sd)
Your use-case isn't clear. However, if you are certain that you need this to be based on the DOM, and not model-data, then this is a way for one directive to have a reference to all elements with another directive specified on them.
The way is that the child directive can require
the parent directive. The parent directive can expose a method that allows direct directive to register their element with the parent directive. Through this, the parent directive can access the child element(s). So if you have a template like:
<div parent-directive>
<div child-directive></div>
<div child-directive></div>
</div>
Then the directives can be coded like:
app.directive('parentDirective', function($window) {
return {
controller: function($scope) {
var registeredElements = [];
this.registerElement = function(childElement) {
registeredElements.push(childElement);
}
}
};
});
app.directive('childDirective', function() {

I tried almost all of above but did not work for me ... The following did
word-break: break-all;
This to be added on the parent div (container of the table .)
Recompiling did the trick for me!
I know this question is older and others already explained it well, I would like to give an example problem which explains the same in simple terms.
Problem: Writing the 1's table.
Solution: -
By Imperative style: =>
1*1=1
1*2=2
1*3=3
.
.
.
1*n=n
By Functional style: =>
1
2
3
.
.
.
n
Explanation in Imperative style we write the instructions more explicitly and which can be called as in more simplified manner.
Where as in Functional style, things which are self-explanatory will be ignored.

The correct way to use LOCK TABLES and UNLOCK TABLES with transactional tables, such as InnoDB tables, is to begin a transaction with SET autocommit = 0 (not START TRANSACTION) followed by LOCK TABLES, and to not call UNLOCK TABLES until you commit the transaction explicitly. For example, if you need to write to table t1 and read from table t2, you can do this:
SET autocommit=0;
LOCK TABLES t1 WRITE, t2 READ, ...;... do something with tables t1 and t2 here ...
COMMIT;
UNLOCK TABLES;
We can add "AwaitTerminationSeconds" property for both taskExecutor and taskScheduler as below,
<property name="awaitTerminationSeconds" value="${taskExecutor .awaitTerminationSeconds}" />
<property name="awaitTerminationSeconds" value="${taskScheduler .awaitTerminationSeconds}" />
Documentation for "waitForTasksToCompleteOnShutdown" property says, when shutdown is called
"Spring's container shutdown continues while ongoing tasks are being completed. If you want this executor to block and wait for the termination of tasks before the rest of the container continues to shut down - e.g. in order to keep up other resources that your tasks may need -, set the "awaitTerminationSeconds" property instead of or in addition to this property."
So it is always advised to use waitForTasksToCompleteOnShutdown and awaitTerminationSeconds properties together. Value of awaitTerminationSeconds depends on our application.
The X-Frame-Options header is a security feature enforced at the browser level.
If you have control over your user base (IT dept for corp app), you could try something like a greasemonkey script (if you can a) deploy greasemonkey across everyone and b) deploy your script in a shared way)...
Alternatively, you can proxy their result. Create an endpoint on your server, and have that endpoint open a connection to the target endpoint, and simply funnel traffic backwards.
My answer will work for anyone wanting to click a definitive area of the page. This worked for me on my absolutely-positioned :after
Thanks to this article, I realized (with jQuery) I can use e.pageY
and e.pageX
instead of worrying about e.offsetY/X
and e.clientY/X
issue between browsers.
Through my trial and error, I started to use the clientX and clientY mouse coordinates in the jQuery event object. These coordinates gave me the X and Y offset of the mouse relative to the top-left corner of the browser's view port. As I was reading the jQuery 1.4 Reference Guide by Karl Swedberg and Jonathan Chaffer, however, I saw that they often referred to the pageX and pageY coordinates. After checking the updated jQuery documentation, I saw that these were the coordinates standardized by jQuery; and, I saw that they gave me the X and Y offset of the mouse relative to the entire document (not just the view port).
I liked this event.pageY
idea because it would always be the same, as it was relative to the document. I can compare it to my :after's parent element using offset(), which returns its X and Y also relative to the document.
Therefore, I can come up with a range of "clickable" region on the entire page that never changes.
Here's my demo on codepen.
or if too lazy for codepen, here's the JS:
* I only cared about the Y values for my example.
var box = $('.box');
// clickable range - never changes
var max = box.offset().top + box.outerHeight();
var min = max - 30; // 30 is the height of the :after
var checkRange = function(y) {
return (y >= min && y <= max);
}
box.click(function(e){
if ( checkRange(e.pageY) ) {
// do click action
box.toggleClass('toggle');
}
});
If you disable the maintain aspect ratio in options then it uses the available height:
var chart = new Chart('blabla', {
type: 'bar',
data: {
},
options: {
maintainAspectRatio: false,
}
});
In Swift 3
Declare variables which we will use
var activityIndicator = UIActivityIndicatorView()
let loadingView = UIView()
let loadingLabel = UILabel()
Set label , view and activityIndicator
func setLoadingScreen(myMsg : String) {
let width: CGFloat = 120
let height: CGFloat = 30
let x = (self.view.frame.width / 2) - (width / 2)
let y = (169 / 2) - (height / 2) + 60
loadingView.frame = CGRect(x: x, y: y, width: width, height: height)
self.loadingLabel.textColor = UIColor.white
self.loadingLabel.textAlignment = NSTextAlignment.center
self.loadingLabel.text = myMsg
self.loadingLabel.frame = CGRect(x: 0, y: 0, width: 160, height: 30)
self.loadingLabel.isHidden = false
self.activityIndicator.activityIndicatorViewStyle = UIActivityIndicatorViewStyle.white
self.activityIndicator.frame = CGRect(x: 0, y: 0, width: 30, height: 30)
self.activityIndicator.startAnimating()
loadingView.addSubview(self.spinner)
loadingView.addSubview(self.loadingLabel)
self.view.addSubview(loadingView)
}
Start Animation
@IBAction func start_animation(_ sender: Any) {
setLoadingScreen(myMsg: "Loading...")
}
Stop Animation
@IBAction func stop_animation(_ sender: Any) {
self.spinner.stopAnimating()
UIApplication.shared.endIgnoringInteractionEvents()
self.loadingLabel.isHidden = true
}

It is generally considered bad practise to have a one to one relationship. This is because you could just have the data represented in one table and achieve the same result.
However, there are instances where you may not be able to make these changes to the table you are referencing. In this instance there is no problem using the Foreign key as the primary key. It might help to have a composite key consisting of an auto incrementing unique primary key and the foreign key.
I am currently working on a system where users can log in and generate a registration code to use with an app. For reasons I won't go into I am unable to simply add the columns required to the users table. So I am going down a one to one route with the codes table.
For persistent key/value storage, you can use kv-bash
, a pure bash implementation of key/value database available at https://github.com/damphat/kv-bash
Usage
git clone https://github.com/damphat/kv-bash
source kv-bash/kv-bash
Try create some permanent variables
kvset myName xyz
kvset myEmail [email protected]
#read the varible
kvget myEmail
#you can also use in another script with $(kvget keyname)
echo $(kvget myEmail)
How about this method:
Set a field in the first object to a new value. If the same field in the second object has the same value, it's probably the same instance. Otherwise, exit as different.
Now set the field in the first object to a different new value. If the same field in the second object has changed to the different value, it's definitely the same instance.
Don't forget to set field in the first object back to it's original value on exit.
Problems?
If it is exactly null
(as opposed to not set):
db.states.find({"cities.name": null})
(but as javierfp points out, it also matches documents that have no cities array at all, I'm assuming that they do).
If it's the case that the property is not set:
db.states.find({"cities.name": {"$exists": false}})
I've tested the above with a collection created with these two inserts:
db.states.insert({"cities": [{name: "New York"}, {name: null}]})
db.states.insert({"cities": [{name: "Austin"}, {color: "blue"}]})
The first query finds the first state, the second query finds the second. If you want to find them both with one query you can make an $or
query:
db.states.find({"$or": [
{"cities.name": null},
{"cities.name": {"$exists": false}}
]})
I struggled to get this working. That's why I'll add a complete solution here:
My objective is to add this header to the SOAP envelope:
<soapenv:Header>
<urn:OTAuthentication>
<urn:AuthenticationToken>TOKEN</urn:AuthenticationToken>
</urn:OTAuthentication>
</soapenv:Header>
First create a SOAPHeaderHandler
class.
import java.util.Set;
import java.util.TreeSet;
import javax.xml.namespace.QName;
import javax.xml.soap.SOAPElement;
import javax.xml.soap.SOAPEnvelope;
import javax.xml.soap.SOAPFactory;
import javax.xml.soap.SOAPHeader;
import javax.xml.ws.handler.MessageContext;
import javax.xml.ws.handler.soap.SOAPHandler;
import javax.xml.ws.handler.soap.SOAPMessageContext;
public class SOAPHeaderHandler implements SOAPHandler<SOAPMessageContext> {
private final String authenticatedToken;
public SOAPHeaderHandler(String authenticatedToken) {
this.authenticatedToken = authenticatedToken;
}
public boolean handleMessage(SOAPMessageContext context) {
Boolean outboundProperty =
(Boolean) context.get(MessageContext.MESSAGE_OUTBOUND_PROPERTY);
if (outboundProperty.booleanValue()) {
try {
SOAPEnvelope envelope = context.getMessage().getSOAPPart().getEnvelope();
SOAPFactory factory = SOAPFactory.newInstance();
String prefix = "urn";
String uri = "urn:api.ecm.opentext.com";
SOAPElement securityElem =
factory.createElement("OTAuthentication", prefix, uri);
SOAPElement tokenElem =
factory.createElement("AuthenticationToken", prefix, uri);
tokenElem.addTextNode(authenticatedToken);
securityElem.addChildElement(tokenElem);
SOAPHeader header = envelope.addHeader();
header.addChildElement(securityElem);
} catch (Exception e) {
e.printStackTrace();
}
} else {
// inbound
}
return true;
}
public Set<QName> getHeaders() {
return new TreeSet();
}
public boolean handleFault(SOAPMessageContext context) {
return false;
}
public void close(MessageContext context) {
//
}
}
setHandlerChain
is required to configure the binding instance with the new chain."Authentication_Service authentication_Service = new Authentication_Service();
Authentication basicHttpBindingAuthentication = authentication_Service.getBasicHttpBindingAuthentication();
String authenticatedToken = "TOKEN";
List<Handler> handlerChain = ((BindingProvider)basicHttpBindingAuthentication).getBinding().getHandlerChain();
handlerChain.add(new SOAPHeaderHandler(authenticatedToken));
((BindingProvider)basicHttpBindingAuthentication).getBinding().setHandlerChain(handlerChain);
Your problem is new (object creation in java style)
MileageFeeCalculator calc = new MileageFeeCalculator();
With annotation @Service
, @Component
, @Configuration
beans are created in the
application context of Spring when server is started. But when we create objects
using new operator the object is not registered in application context which is already created. For Example Employee.java class i have used.
Check this out:
public class ConfiguredTenantScopedBeanProcessor implements BeanFactoryPostProcessor {
@Override
public void postProcessBeanFactory(ConfigurableListableBeanFactory beanFactory) throws BeansException {
String name = "tenant";
System.out.println("Bean factory post processor is initialized");
beanFactory.registerScope("employee", new Employee());
Assert.state(beanFactory instanceof BeanDefinitionRegistry,
"BeanFactory was not a BeanDefinitionRegistry, so CustomScope cannot be used.");
BeanDefinitionRegistry registry = (BeanDefinitionRegistry) beanFactory;
for (String beanName : beanFactory.getBeanDefinitionNames()) {
BeanDefinition definition = beanFactory.getBeanDefinition(beanName);
if (name.equals(definition.getScope())) {
BeanDefinitionHolder proxyHolder = ScopedProxyUtils.createScopedProxy(new BeanDefinitionHolder(definition, beanName), registry, true);
registry.registerBeanDefinition(beanName, proxyHolder.getBeanDefinition());
}
}
}
}
Note that the use of unescape()
is deprecated and doesn't work with the TypeScript compiler, for example.
Based on radicand's answer and the comments section below, here's an updated solution:
var string = "http\\u00253A\\u00252F\\u00252Fexample.com";
decodeURIComponent(JSON.parse('"' + string.replace(/\"/g, '\\"') + '"'));

Using a clip-path is a new, up and coming alternative. Its starting to get supported more and more and is now becoming well documented. Since it uses SVG to create the shape, it is responsive straight out of the box.

No, it doesn't save you memory.
Also note that you don't have to import Math
at all. Everything in java.lang
is imported automatically.
A better example would be something like an ArrayList
import java.util.ArrayList;
....
ArrayList<String> i = new ArrayList<String>();
Note I'm importing the ArrayList
specifically. I could have done
import java.util.*;
But you generally want to avoid large wildcard imports to avoid the problem of collisions between packages.
UIView *view = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 110, 50)];
view.backgroundColor = [UIColor clearColor];
UIButton *settingsButton = [UIButton buttonWithType:UIButtonTypeCustom];
[settingsButton setImage:[UIImage imageNamed:@"settings_icon_png.png"] forState:UIControlStateNormal];
[settingsButton addTarget:self action:@selector(logOutClicked) forControlEvents:UIControlEventTouchUpInside];
[settingsButton setFrame:CGRectMake(40,5,32,32)];
[view addSubview:settingsButton];
UIButton *filterButton = [UIButton buttonWithType:UIButtonTypeCustom];
[filterButton setImage:[UIImage imageNamed:@"filter.png"] forState:UIControlStateNormal];
[filterButton addTarget:self action:@selector(openActionSheet) forControlEvents:UIControlEventTouchUpInside];
[filterButton setFrame:CGRectMake(80,5,32,32)];
[view addSubview:filterButton];
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:view];
The scanner can also use delimiters other than whitespace.
Easy example from Scanner API:
String input = "1 fish 2 fish red fish blue fish";
// \\s* means 0 or more repetitions of any whitespace character
// fish is the pattern to find
Scanner s = new Scanner(input).useDelimiter("\\s*fish\\s*");
System.out.println(s.nextInt()); // prints: 1
System.out.println(s.nextInt()); // prints: 2
System.out.println(s.next()); // prints: red
System.out.println(s.next()); // prints: blue
// don't forget to close the scanner!!
s.close();
The point is to understand the regular expressions (regex
) inside the Scanner::useDelimiter
. Find an useDelimiter
tutorial here.
To start with regular expressions here you can find a nice tutorial.
abc… Letters
123… Digits
\d Any Digit
\D Any Non-digit character
. Any Character
\. Period
[abc] Only a, b, or c
[^abc] Not a, b, nor c
[a-z] Characters a to z
[0-9] Numbers 0 to 9
\w Any Alphanumeric character
\W Any Non-alphanumeric character
{m} m Repetitions
{m,n} m to n Repetitions
* Zero or more repetitions
+ One or more repetitions
? Optional character
\s Any Whitespace
\S Any Non-whitespace character
^…$ Starts and ends
(…) Capture Group
(a(bc)) Capture Sub-group
(.*) Capture all
(ab|cd) Matches ab or cd
This is the shortest I could find.
List version
public List<Integer> makeSequence(int begin, int end)
{
List<Integer> ret = new ArrayList<Integer>(++end - begin);
for (; begin < end; )
ret.add(begin++);
return ret;
}
Array Version
public int[] makeSequence(int begin, int end)
{
if(end < begin)
return null;
int[] ret = new int[++end - begin];
for (int i=0; begin < end; )
ret[i++] = begin++;
return ret;
}
Changes to be committed: (use "git reset HEAD ..." to unstage)
var err;
Promise.all([
promiseOne().catch(function(error) { err = error;}),
promiseTwo().catch(function(error) { err = error;})
]).then(function() {
if (err) {
throw err;
}
});
The Promise.all
will swallow any rejected promise and store the error in a variable, so it will return when all of the promises have resolved. Then you can re-throw the error out, or do whatever. In this way, I guess you would get out the last rejection instead of the first one.
It's same as vikasdumca's steps, but thought to share the link.
run the following command
sudo apt-get install python-software-properties
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
then
sudo apt-get install oracle-java8-installer
this would install oracle java 8 on ubuntu properly.

The Adjusted R-squared is close to, but different from, the value of R2. Instead of being based on the explained sum of squares SSR and the total sum of squares SSY, it is based on the overall variance (a quantity we do not typically calculate), s2T = SSY/(n - 1) and the error variance MSE (from the ANOVA table) and is worked out like this: adjusted R-squared = (s2T - MSE) / s2T.
This approach provides a better basis for judging the improvement in a fit due to adding an explanatory variable, but it does not have the simple summarizing interpretation that R2 has.
If I haven't made a mistake, you should verify the values of adjusted R-squared and R-squared as follows:
s2T <- sum(anova(v.lm)[[2]]) / sum(anova(v.lm)[[1]])
MSE <- anova(v.lm)[[3]][2]
adj.R2 <- (s2T - MSE) / s2T
On the other side, R2 is: SSR/SSY, where SSR = SSY - SSE
attach(v)
SSE <- deviance(v.lm) # or SSE <- sum((epm - predict(v.lm,list(n_days)))^2)
SSY <- deviance(lm(epm ~ 1)) # or SSY <- sum((epm-mean(epm))^2)
SSR <- (SSY - SSE) # or SSR <- sum((predict(v.lm,list(n_days)) - mean(epm))^2)
R2 <- SSR / SSY
This is a simple timer class in swift that enables you to:
SimpleTimer(interval: 3,repeats: true){print("tick")}.start()//Ticks every 3 secs
class SimpleTimer {/*<--was named Timer, but since swift 3, NSTimer is now Timer*/
typealias Tick = ()->Void
var timer:Timer?
var interval:TimeInterval /*in seconds*/
var repeats:Bool
var tick:Tick
init( interval:TimeInterval, repeats:Bool = false, onTick:@escaping Tick){
self.interval = interval
self.repeats = repeats
self.tick = onTick
}
func start(){
timer = Timer.scheduledTimer(timeInterval: interval, target: self, selector: #selector(update), userInfo: nil, repeats: true)//swift 3 upgrade
}
func stop(){
if(timer != nil){timer!.invalidate()}
}
/**
* This method must be in the public or scope
*/
@objc func update() {
tick()
}
}
Create an Extension Method most likely you will want to use this more than once and this prevents duplicate code.
Implementation:
public static void AddRange<T, S>(this Dictionary<T, S> source, Dictionary<T, S> collection)
{
if (collection == null)
{
throw new ArgumentNullException("Collection is null");
}
foreach (var item in collection)
{
if(!source.ContainsKey(item.Key)){
source.Add(item.Key, item.Value);
}
else
{
// handle duplicate key issue here
}
}
}
Usage:
Dictionary<string,string> animals = new Dictionary<string,string>();
Dictionary<string,string> newanimals = new Dictionary<string,string>();
animals.AddRange(newanimals);
You can use the HttpWebRequest class to perform a request and retrieve a response from a given URL. You'll use it like:
Try
Dim fr As System.Net.HttpWebRequest
Dim targetURI As New Uri("http://whatever.you.want.to.get/file.html")
fr = DirectCast(HttpWebRequest.Create(targetURI), System.Net.HttpWebRequest)
If (fr.GetResponse().ContentLength > 0) Then
Dim str As New System.IO.StreamReader(fr.GetResponse().GetResponseStream())
Response.Write(str.ReadToEnd())
str.Close();
End If
Catch ex As System.Net.WebException
'Error in accessing the resource, handle it
End Try
HttpWebRequest is detailed at: http://msdn.microsoft.com/en-us/library/system.net.httpwebrequest.aspx
A second option is to use the WebClient class, this provides an easier to use interface for downloading web resources but is not as flexible as HttpWebRequest:
Sub Main()
'Address of URL
Dim URL As String = http://whatever.com
' Get HTML data
Dim client As WebClient = New WebClient()
Dim data As Stream = client.OpenRead(URL)
Dim reader As StreamReader = New StreamReader(data)
Dim str As String = ""
str = reader.ReadLine()
Do While str.Length > 0
Console.WriteLine(str)
str = reader.ReadLine()
Loop
End Sub
More info on the webclient can be found at: http://msdn.microsoft.com/en-us/library/system.net.webclient.aspx

See the docs for to_dict
. You can use it like this:
df.set_index('id').to_dict()
And if you have only one column, to avoid the column name is also a level in the dict (actually, in this case you use the Series.to_dict()
):
df.set_index('id')['value'].to_dict()
In Swift you would do it like this:
label.lineBreakMode = NSLineBreakMode.ByWordWrapping
label.numberOfLines = 0
(Note that the way the lineBreakMode constant works is different to in ObjC)
I guess this what you are exactly looking for

for line in lines :
if line.startswith( "Path=" ):
output_line=line[(line.find("Path=")+len("Path=")):]

The key of your state should be the same as the name of your input field. Then you can do this in the handleEvent method;
this.setState({
[event.target.name]: event.target.value
});
babel-core
, babel-polyfill
, babel-preset-es2015
.babelrc
with contents: { "presets": ["es2015"] }
import
statement in your main entry file, use another file eg: app.js
and your main entry file should required babel-core/register
and babel-polyfill
to make babel works separately at the first place before anything else. Then you can require app.js
where import
statement.Example:
index.js
require('babel-core/register');
require('babel-polyfill');
require('./app');
app.js
import co from 'co';
It should works with node index.js
.
INSERT
statements that useVALUES
syntax can insert multiple rows. To do this, include multiple lists of column values, each enclosed within parentheses and separated by commas.
Example:
INSERT INTO tbl_name
(a,b,c)
VALUES
(1,2,3),
(4,5,6),
(7,8,9);
Some years later, looking for the same requirement, I found a CSS option using background-size.
It is supposed to work in modern browsers (IE9+).
<div id="container" style="background-image:url(myimage.png)">
</div>
And the style:
#container
{
width: 100px; /*or 70%, or what you want*/
height: 200px; /*or 70%, or what you want*/
background-size: cover;
background-position: center;
background-repeat: no-repeat;
}
The reference: http://www.w3schools.com/cssref/css3_pr_background-size.asp
And the demo: http://www.w3schools.com/cssref/playit.asp?filename=playcss_background-size

Doesn't work in internet explorer 7... but who cares ?
I tried several of these answers to no avail for android using react-native version = 0.19.0.
For some reason, the resizeMode inside my stylesheet did not work appropriately? However, when sytlesheet had
backgroundImage: {
flex: 1,
width: null,
height: null,
}
and, within the Image tag I specified the resizeMode:
<Image source={require('path/to/image.png')} style= {styles.backgroundImage} resizeMode={Image.resizeMode.sretch}>
It worked perfectly! As mentioned above, you can use Image.resizeMode.cover or contain as well.
Hope this helps!
Update: Handling this in CSS is wonderfully simple and low overhead, but you have no control over where breaks occur when they do. That's fine if you don't care, or your data has long alphanumeric runs without any natural breaks. We had lots of long file paths, URLs, and phone numbers, all of which have places it's significantly better to break at than others.
Our solution was to first use a regex replacement to put a zero-width space (​) after every 15 (say) characters that aren't whitespace or one of the special characters where we'd prefer breaks. We then do another replacement to put a zero-width space after those special characters.
Zero-width spaces are nice, because they aren't ever visible on screen; shy hyphens were confusing when they showed, because the data has significant hyphens. Zero-width spaces also aren't included when you copy text out of the browser.
The special break characters we're currently using are period, forward slash, backslash, comma, underscore, @, |, and hyphen. You wouldn't think you'd need do anything to encourage breaking after hyphens, but Firefox (3.6 and 4 at least) doesn't break by itself at hyphens surrounded by numbers (like phone numbers).
We also wanted to control the number of characters between artificial breaks, based on the layout space available. That meant that the regex to match long non-breaking runs needed to be dynamic. This gets called a lot, and we didn't want to be creating the same identical regexes over and over for performance reasons, so we used a simple regex cache, keyed by the regex expression and its flags.
Here's the code; you'd probably namespace the functions in a utility package:
makeWrappable = function(str, position)
{
if (!str)
return '';
position = position || 15; // default to breaking after 15 chars
// matches every requested number of chars that's not whitespace or one of the special chars defined below
var longRunsRegex = cachedRegex('([^\\s\\.\/\\,_@\\|-]{' + position + '})(?=[^\\s\\.\/\\,_@\\|-])', 'g');
return str
.replace(longRunsRegex, '$1​') // put a zero-width space every requested number of chars that's not whitespace or a special char
.replace(makeWrappable.SPECIAL_CHARS_REGEX, '$1​'); // and one after special chars we want to allow breaking after
};
makeWrappable.SPECIAL_CHARS_REGEX = /([\.\/\\,_@\|-])/g; // period, forward slash, backslash, comma, underscore, @, |, hyphen
cachedRegex = function(reString, reFlags)
{
var key = reString + (reFlags ? ':::' + reFlags : '');
if (!cachedRegex.cache[key])
cachedRegex.cache[key] = new RegExp(reString, reFlags);
return cachedRegex.cache[key];
};
cachedRegex.cache = {};
Test like this:
makeWrappable('12345678901234567890 12345678901234567890 1234567890/1234567890')
Update 2: It appears that zero-width spaces in fact are included in copied text in at least some circumstances, you just can't see them. Obviously, encouraging people to copy text with hidden characters in it is an invitation to have data like that entered into other programs or systems, even your own, where it may cause problems. For instance, if it ends up in a database, searches against it may fail, and search strings like this are likely to fail too. Using arrow keys to move through data like this requires (rightly) an extra keypress to move across the character you can't see, somewhat bizarre for users if they notice.
In a closed system, you can filter that character out on input to protect yourself, but that doesn't help other programs and systems.
All told, this technique works well, but I'm not certain what the best choice of break-causing character would be.
Update 3: Having this character end up in data is no longer a theoretical possibility, it's an observed problem. Users submit data copied off the screen, it gets saved in the db, searches break, things sort weirdly etc..
We did two things:
This works well, as does the technique itself, but it's a cautionary tale.
Update 4: We're using this in a context where the data fed to this may be HTML escaped. Under the right circumstances, it can insert zero-width spaces in the middle of HTML entities, with funky results.
Fix was to add ampersand to the list of characters we don't break on, like this:
var longRunsRegex = cachedRegex('([^&\\s\\.\/\\,_@\\|-]{' + position + '})(?=[^&\\s\\.\/\\,_@\\|-])', 'g');
my_df = pd.DataFrame.from_dict(my_dict, orient='index', columns=['my_col'])
.. would have parsed the dict properly (putting each dict key into a separate df column, and key values into df rows), so the dicts would not get squashed into a single column in the first place.
Some pages may require more than login/pass. There may even be hidden fields. The most reliable way is to use inspect tool and look at the network tab while logging in, to see what data is being passed on.
Subprocess is based on popen2, and as such has a number of advantages - there's a full list in the PEP here, but some are:
-- TRY THIS --
select name= case when isnumeric(empname)= 1 then 'numeric' else 'notmumeric' end from [Employees]
But conversion is quit impossible
select empname=
case
when isnumeric(empname)= 1 then empname
else 'notmumeric'
end
from [Employees]
as a workaround you can use the stdin device in /dev directory
....| for item in `cat /dev/stdin` ; do echo $item ;done
In your asp.net app use this
using System.Configuration;
Response.Write(ConfigurationManager.OpenMachineConfiguration().FilePath);
Simply use this:
var date = new Date('1970-01-01'); // Or your date here
console.log((date.getMonth() + 1) + '/' + date.getDate() + '/' + date.getFullYear());
Simple and sweet ;)

Do you have a specific scenario in mind you need assistance with?
For future viewers, there is a line in my /etc/nanorc file close to line 153 that says "set tabsize 8". The word might need to be tabsize instead of tabspace. After I replaced 8 with 4 and uncommented the line, it solved my problem.
Okay, how about a CSS answer! We use display: table
. Then each of the divs are rows, and finally we apply height of 100% to middle 'row' and voilà.
body { display: table; }
div { display: table-row; }
#content {
width:450px;
margin:0 auto;
text-align: center;
background-color: blue;
color: white;
height: 100%;
}
You can provide your own sort function to list.sort()
:
The sort() method takes optional arguments for controlling the comparisons.
cmp specifies a custom comparison function of two arguments (list items) which should return a negative, zero or positive number depending on whether the first argument is considered smaller than, equal to, or larger than the second argument:
cmp=lambda x,y: cmp(x.lower(), y.lower())
. The default value isNone
.key specifies a function of one argument that is used to extract a comparison key from each list element:
key=str.lower
. The default value isNone
.reverse is a boolean value. If set to True, then the list elements are sorted as if each comparison were reversed.
In general, the key and reverse conversion processes are much faster than specifying an equivalent cmp function. This is because cmp is called multiple times for each list element while key and reverse touch each element only once.
An enhanced for
loop is just limiting the number of parameters inside the parenthesis.
for (int i = 0; i < myArray.length; i++) {
System.out.println(myArray[i]);
}
Can be written as:
for (int myValue : myArray) {
System.out.println(myValue);
}
You need to print the result of the getText()
. You're currently printing the object TxtBoxContent
.
getText()
will only get the inner text of an element. To get the value, you need to use getAttribute()
.
WebElement TxtBoxContent = driver.findElement(By.id(WebelementID));
System.out.println("Printing " + TxtBoxContent.getAttribute("value"));
In my case I had to uninstall and reinstall the wireless adapter driver to be able to execute the command
The downside of INFORMATION_SCHEMA.TABLES
is that it also includes system tables such as dtproperties
and the MSpeer_...
tables, with no way to tell them apart from your own tables.
I would recommend using sys.objects
(the new version of the deprecated sysobjects view), which does support excluding the system tables:
select *
from sys.objects
where type = 'U' -- User tables
and is_ms_shipped = 0 -- Exclude system tables
This is not issue but this is by design. The root cause is described in Microsoft Support Page.
The Response.End method ends the page execution and shifts the execution to the Application_EndRequest event in the application's event pipeline. The line of code that follows Response.End is not executed.

Use var
instead of int
for your clicks
variable generation and onClick
instead of click
as your function name:
var clicks = 0;
function onClick() {
clicks += 1;
document.getElementById("clicks").innerHTML = clicks;
};
_x000D_
<button type="button" onClick="onClick()">Click me</button>
<p>Clicks: <a id="clicks">0</a></p>
_x000D_
In JavaScript variables are declared with the var
keyword. There are no tags like int
, bool
, string
... to declare variables. You can get the type of a variable with 'typeof(yourvariable)', more support about this you find on Google.
And the name 'click' is reserved by JavaScript for function names so you have to use something else.
If you are searching for haml then this is the answer for hidden field to set value to a hidden field like
%input#forum_id.hidden
In your jquery just convert the value to string and then append it using attr property in jquery. hope this also works in other languages also.
$('#forum_id').attr('val',forum_id.toString());

Unfortunately, git branch -a
and git branch -r
do not show you all remote branches, if you haven't executed a "git fetch".
git remote show origin
works consistently all the time. Also git show-ref
shows all references in the Git repository. However, it works just like the git branch
command.
If you're ok with creating class methods and want the characters you chop off, try this:

amount.times.inject([self, '']){ |(s, r)| [s.chop, r.prepend(s[-1])] }
end
end
hello, world = "hello world".chop_multiple 5

What is your project type? If it's a "Win32 project", your entry point should be (w)WinMain
. If it's a "Win32 Console Project", then it should be (w)main
. The name _tmain
is #defined to be either main
or wmain
depending on whether UNICODE is defined or not.
If it's a DLL, then DllMain
.
The project type can be seen under project properties, Linker, System, Subsystem. It would say either "Console" or "Windows".
Note that the entry point name varies depending on whether UNICODE is defined or not. In VS2008, it's defined by default.
The proper prototype for main is either
int _tmain(int argc, _TCHAR* argv[])
or
int _tmain()
Make sure it's one of those.
EDIT:
If you're getting an error on _TCHAR, place an
#include <tchar.h>
If you think the issue is with one of the headers, go to the properties of the file with main(), and under Preprocessor, enable generating of the preprocessed file. Then compile. You'll get a file with the same name a .i extension. Open it, and see if anything unsavory happened to the main() function. There can be rogue #defines in theory...
EDIT2:
With UNICODE defined (which is the default), the linker expects the entry point to be wmain(), not main(). _tmain has the advantage of being UNICODE-agnostic - it translates to either main or wmain.
Some time ago, there was a reason to maintain both an ANSI build and a Unicode build. Unicode support was sorely incomplete in Windows 95/98/Me. The primary APIs were ANSI, and Unicode versions existed here and there, but not pervasively. Also, the VS debugger had trouble displaying Unicode strings. In the NT kernel OSes (that's Windows 2000/XP/Vista/7/8/10), Unicode support is primary, and ANSI functions are added on top. So ever since VS2005, the default upon project creation is Unicode. That means - wmain. They could not keep the same entry point name because the parameter types are different. _TCHAR is #defined to be either char or wchar_t. So _tmain is either main(int argc, char **argv) or wmain(int argc, wchar_t **argv).
The reason you were getting an error at _tmain
at some point was probably because you did not change the type of argv
to _TCHAR**
.
If you're not planning to ever support ANSI (probably not), you can reformulate your entry point as
int wmain(int argc, wchar_t *argv[])
and remove the tchar.h
include line.
The following examples use new Set()
to create a filtered array that has only unique elements:
Array with primitive data types: string, number, boolean, null, undefined, symbol:
const a = [1, 2, 3, 4];
const b = [3, 4, 5];
const c = Array.from(new Set(a.concat(b)));
Array with objects as items:
const a = [{id:1}, {id: 2}, {id: 3}, {id: 4}];
const b = [{id: 3}, {id: 4}, {id: 5}];
const stringifyObject = o => JSON.stringify(o);
const parseString = s => JSON.parse(s);
const c = Array.from(new Set(a.concat(b).map(stringifyObject)), parseString);

Make another div and add both 'dummy' and 'img-container' inside the div
Do HTML and CSS like follows
html , body {height:100%;}_x000D_
.responsive-container { height:100%; display:table; text-align:center; width:100%;}_x000D_
.inner-container {display:table-cell; vertical-align:middle;}
_x000D_
<div class="responsive-container">_x000D_
<div class="inner-container">_x000D_
<div class="dummy">Sample</div>_x000D_
<div class="img-container">_x000D_
Image tag_x000D_
</div>_x000D_
</div> _x000D_
</div>
_x000D_
Instead of 100% for the 'responsive-container' you can give the height that you want.,
If you support flash you can use https://everyplay.com/assets/clipboard.swf and use the flashvars text to set the text
https://everyplay.com/assets/clipboard.swf?text=It%20Works
Thats the one i use to copy and you can set as extra if doesn't support these options you can use :
For Internet Explorer: window.clipboardData.setData(DataFormat, Text) and window.clipboardData.getData(DataFormat)
You can use the DataFormat's Text and Url to getData and setData.
And to delete data:
You can use the DataFormat's File, HTML, Image, Text and URL. PS: You Need To Use window.clipboardData.clearData(DataFormat);
And for other thats not support window.clipboardData and swf flash files you can also use control + c button on your keyboard for windows and for mac its command + c
You should be okay to just take the height property out of the CSS.

The keydown
event will work fine for Escape and has the benefit of allowing you to use keyCode
in all browsers. Also, you need to attach the listener to document
rather than the body.
Update May 2016
keyCode
is now in the process of being deprecated and most modern browsers offer the key
property now, although you'll still need a fallback for decent browser support for now (at time of writing the current releases of Chrome and Safari don't support it).
Update September 2018
evt.key
is now supported by all modern browsers.
document.onkeydown = function(evt) {_x000D_
evt = evt || window.event;_x000D_
var isEscape = false;_x000D_
if ("key" in evt) {_x000D_
isEscape = (evt.key === "Escape" || evt.key === "Esc");_x000D_

Whenever a shared lib is loaded, the loader (the code on the OS which load any program you run) changes some addresses in the code depending on where the object was loaded to.
In the above example, the "111" in the non-PIC code is written by the loader the first time it was loaded.
For not shared objects, you may want it to be like that because the compiler can make some optimizations on that code.
For shared object, if another process will want to "link" to that code he must read it to the same virtual addresses or the "111" will make no sense. but that virtual-space may already be in use in the second process.

@powershell -NoProfile -ExecutionPolicy unrestricted -Command "iex ((new-object net.webclient).DownloadString('https://chocolatey.org/install.ps1'))" && SET PATH=%PATH%;%ALLUSERSPROFILE%\chocolatey\bin
Then, use Powershell to get the redis package from chocolatey: http://chocolatey.org/packages/redis-64
choco install redis-64
Redis will be installed in something like C:\ProgramData\chocolatey\lib\redis-64.2.8.9
Windows PowerShell Copyright (C) 2013 Microsoft Corporation. All rights reserved.
PS C:\windows\system32> choco install redis-64 Chocolatey (v0.9.8.27) is installing 'redis-64' and dependencies. By installing you accept the license for 'redis-64' an d each dependency you are installing.

How to total up used memory by process name:
Sometimes even looking at the biggest single processes there is still a lot of used memory unaccounted for. To check if there are a lot of the same smaller processes using the memory you can use a command like the following which uses awk to sum up the total memory used by processes of the same name:
ps -e -orss=,args= |awk '{print $1 " " $2 }'| awk '{tot[$2]+=$1;count[$2]++} END {for (i in tot) {print tot[i],i,count[i]}}' | sort -n
e.g. output
9344 docker 1
9948 nginx: 4
22500 /usr/sbin/NetworkManager 1
24704 sleep 69
26436 /usr/sbin/sshd 15

Try this:
this.getSupportActionBar().hide();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
try
{
this.getSupportActionBar().hide();
}
catch (NullPointerException e){}
setContentView(R.layout.activity_main);
}
This works perfectly:
import sys
sys.stdout=open("test.txt","w")
print ("hello")
sys.stdout.close()
Now the hello will be written to the test.txt file. Make sure to close the stdout
with a close
, without it the content will not be save in the file
A DataInputStream
is just a decorator over an InputStream
(which System.in
is) which allows to read using more convenient methods.
As to the Float.valueOf()
, well, that's curious because Float
has .parseFloat()
as well. Here the code grabs a Float
with .valueOf()
which it turns into the primitive float
type using .floatValue()
, which is unnecessary with Java 1.5+ due to auto unboxing.
And as other answers rightly say, these methods are obsolete anyway.
"Why should every SELECT always include DISTINCT ?"
str.match(/.{3}/g); // => ['abc', 'def', 'ghi', 'jkl']
Using some of the info here, I came up with the following component which you can use within your route declarations. It's compatible with React Router v4.
It's using typescript, but should be fairly straight-forward to convert to native javascript:
interface Props {
exact?: boolean;
link: string;
path: string;
sensitive?: boolean;
strict?: boolean;
}
const ExternalRedirect: React.FC<Props> = (props: Props) => {
const { link, ...routeProps } = props;
return (
<Route
{...routeProps}
render={() => {
window.location.replace(props.link);
return null;
}}
/>
);
};
And use with:
<ExternalRedirect
exact={true}
path={'/privacy-policy'}
link={'https://example.zendesk.com/hc/en-us/articles/123456789-Privacy-Policies'}
/>
Because all previous answers doesn't work for me for ubuntu 14.04 here what I did, if any one get the same problem:
git clone https://github.com/Linuxbrew/brew.git ~/.linuxbrew
PATH="$HOME/.linuxbrew/bin:$PATH"
export MANPATH="$(brew --prefix)/share/man:$MANPATH"
export INFOPATH="$(brew --prefix)/share/info:$INFOPATH"
then
sudo apt-get install gawk
sudo yum install gawk
brew install hello

You can store any kind of data in a session using:
Session["VariableName"]=value;
This variable will last 20 mins or so.
You can also do cd ......\ as many times as there are folders that takes you to home directory. For example, if you are in cd:\windows\syatem32, then cd ....\ takes you to the home, that is c:\
This works for me :
$db = mysqli_connect('localhost', 'UserName', 'Password', 'DB_Name') or die('Not Connected');
mysqli_set_charset($db, 'utf8');
$sql = mysqli_query($db,"SELECT * FROM `mytable` WHERE city='c7'");
$sql = mysqli_fetch_assoc($sql);
$Checker = $sql['city'];
if ($Checker != null) {
echo 'Already exists';
} else {
echo 'Not found';
}
This error occurred for me because i was trying to store the minimum date and time in a column using inline queries directly from C# code.
The date variable was set to 01/01/0001 12:00:00 AM in the code given the fact that DateTime in C# is initialized with this date and time if not set elsewise. And the least possible date allowed in the MS-SQL 2008 datetime datatype is 1753-01-01 12:00:00 AM.
I changed the date from the code and set it to 01/01/1900 and no errors were reported further.

How about http://www.javatuples.org/index.html I have found it very useful.
The javatuples offers you tuple classes from one to ten elements:
Unit<A> (1 element)
Pair<A,B> (2 elements)
Triplet<A,B,C> (3 elements)
Quartet<A,B,C,D> (4 elements)
Quintet<A,B,C,D,E> (5 elements)
Sextet<A,B,C,D,E,F> (6 elements)
Septet<A,B,C,D,E,F,G> (7 elements)
Octet<A,B,C,D,E,F,G,H> (8 elements)
Ennead<A,B,C,D,E,F,G,H,I> (9 elements)
Decade<A,B,C,D,E,F,G,H,I,J> (10 elements)
You might also consider the smart_open
module, which supports iterators:
from smart_open import smart_open
# stream lines from an S3 object
for line in smart_open('s3://mybucket/mykey.txt', 'rb'):
print(line.decode('utf8'))
and context managers:
with smart_open('s3://mybucket/mykey.txt', 'rb') as s3_source:
for line in s3_source:
print(line.decode('utf8'))
s3_source.seek(0) # seek to the beginning
b1000 = s3_source.read(1000) # read 1000 bytes
Find smart_open
at https://pypi.org/project/smart_open/
Use the enumerate()
function to generate the index along with the elements of the sequence you are looping over:
for index, w in enumerate(loopme):
print "CURRENT WORD IS", w, "AT CHARACTER", index
You could try setting up a filter using the unicodedata.category()
function:
import unicodedata
printable = {'Lu', 'Ll'}
def filter_non_printable(str):
return ''.join(c for c in str if unicodedata.category(c) in printable)
See Table 4-9 on page 175 in the Unicode database character properties for the available categories
Sorry, but did any of the given solutions on this thread actually answer the question that was asked?
I have a String date and a date format which is different. Ex.: date: 2016-10-19 dateFormat: "DD-MM-YYYY". I need to check if this date is a valid date.
The following works for me...
const date = '2016-10-19';
const dateFormat = 'DD-MM-YYYY';
const toDateFormat = moment(new Date(date)).format(dateFormat);
moment(toDateFormat, dateFormat, true).isValid();
// Note: `new Date()` circumvents the warning that
// Moment throws (https://momentjs.com/guides/#/warnings/js-date/),
// but may not be optimal.
But honestly, don't understand why moment.isDate()
(as documented) only accepts an object. Should also support a string in my opinion.
x = [1, 10, 100]
for i in x:
print '%02d' % i
results in:
01
10
100
Read more information about string formatting using % in the documentation.
Assuming the key is contained inside the <appSettings>
node:
ConfigurationSettings.AppSettings["theKey"];
As for "writing" - put simply, dont.
The web.config is not designed for that, if you're going to be changing a value constantly, put it in a static helper class.
Eclipse 3.4 has a Favourites section under Window->Preferences->Java->Editor->Content Assist
If you use org.junit.Assert
a lot, you might find some value to adding it there.
This is a more general answer to the missing "Select cond1, stmt1, ... else stmtelse" connstruction in R. It's a bit gassy, but it works an resembles the switch statement present in C
while (TRUE) {
if (is.na(val)) {
val <- "NULL"
break
}
if (inherits(val, "POSIXct") || inherits(val, "POSIXt")) {
val <- paste0("#", format(val, "%Y-%m-%d %H:%M:%S"), "#")
break
}
if (inherits(val, "Date")) {
val <- paste0("#", format(val, "%Y-%m-%d"), "#")
break
}
if (is.numeric(val)) break
val <- paste0("'", gsub("'", "''", val), "'")
break
}
from app import SQLAlchemyDB as db
Chance.query.filter(Chance.repo_id==repo_id,
Chance.status=="1",
db.func.date(Chance.apply_time)<=end,
db.func.date(Chance.apply_time)>=start).count()
it is equal to:
select
count(id)
from
Chance
where
repo_id=:repo_id
and status='1'
and date(apple_time) <= end
and date(apple_time) >= start
wish can help you.
do you called the ViewTreeObserver and not remove it.
mEtEnterlive.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
// do nothing here can cause such problem
});
Inspired by Robert K's solution, strips html tags and prevents executing scripts and eventhandlers like: <img src=fake onerror="prompt(1)">
Tested on latest Chrome, FF, IE (should work from IE9, but haven't tested).
var decodeEntities = (function () {
//create a new html document (doesn't execute script tags in child elements)
var doc = document.implementation.createHTMLDocument("");
var element = doc.createElement('div');
function getText(str) {
element.innerHTML = str;
str = element.textContent;
element.textContent = '';
return str;
}
function decodeHTMLEntities(str) {
if (str && typeof str === 'string') {
var x = getText(str);
while (str !== x) {
str = x;
x = getText(x);
}
return x;
}
}
return decodeHTMLEntities;
})();
Simply call:
decodeEntities('<img src=fake onerror="prompt(1)">');
decodeEntities("<script>alert('aaa!')</script>");
