Works in IE9 documentMode for me.

Without a X-UA-Compatible header/meta to set an explicit documentMode, you'll get a mode based on:

• whether the user has clicked the ‘compatibility view’ button in that domain before;
• perhaps also whether this has happened automatically due to some other content on the site causing IE8/9's renderer to crash and fall back to the old renderer;
• whether the user has opted to put all sites in compatibility view by default;
• whether IE thinks the site is on your intranet and so defaults to compatibility view;
• whether the site in question is in Microsoft's own list of websites that require compatibility view.

You can change these settings from ‘Tools -> Compatibility view settings’ from the IE menu. Of course that menu is now sneakily hidden, so you won't see it until you press Alt.

As a site author, if you're confident that your site complies to standards (renders well in other browsers, and uses feature-sniffing to decide what browser workarounds to use), I suggest using:

<meta http-equiv="X-UA-Compatible" content="IE=Edge"/>

or the HTTP header:

X-UA-Compatible: IE=Edge

to get the latest renderer whatever IE version is in use.

We can resolve this problem in Spring-Apache-tomcat environment by adding one single line in RequestInterceptor method -

//before the actual handler will be executed
public boolean preHandle(HttpServletRequest request,
HttpServletResponse response, Object handler)
throws Exception {

// Some logic

// below statement ensures IE trusts the page formatting and will render it acc. to IE 8 standard.
response.addHeader("X-UA-Compatible", "IE=8"); 

return true;
}

Reference from - How to create filter and modify response header It covers how we can resolve this problem via a RequestInterceptor (Spring).

I just need to initialize all the array elements to Boolean false.

Either use boolean[] instead so that all values defaults to false:

boolean[] array = new boolean[size];

Or use Arrays#fill() to fill the entire array with Boolean.FALSE:

Boolean[] array = new Boolean[size];
Arrays.fill(array, Boolean.FALSE);

Also note that the array index is zero based. The freq[Global.iParameter[2]] = false; line as you've there would cause ArrayIndexOutOfBoundsException. To learn more about arrays in Java, consult this basic Oracle tutorial.

Just consider how the SWITCH might work,

• in case of primitives we know it can fail with NPE for auto-boxing
• but for String or enum, it might be invoking equals method, which obviously needs a LHS value on which equals is being invoked. So, given no method can be invoked on a null, switch cant handle null.

If you want a generic solution without boxing:

public class KeyBasedEqualityComparer<T, TKey> : IEqualityComparer<T>
{
    private readonly Func<T, TKey> _keyGetter;

    public KeyBasedEqualityComparer(Func<T, TKey> keyGetter)
    {
        _keyGetter = keyGetter;
    }

    public bool Equals(T x, T y)
    {
        return EqualityComparer<TKey>.Default.Equals(_keyGetter(x), _keyGetter(y));
    }

    public int GetHashCode(T obj)
    {
        TKey key = _keyGetter(obj);

        return key == null ? 0 : key.GetHashCode();
    }
}

public static class KeyBasedEqualityComparer<T>
{
    public static KeyBasedEqualityComparer<T, TKey> Create<TKey>(Func<T, TKey> keyGetter)
    {
        return new KeyBasedEqualityComparer<T, TKey>(keyGetter);
    }
}

usage:

KeyBasedEqualityComparer<Class_reglement>.Create(x => x.Numf)

typeof is applied to a name of a type or generic type parameter known at compile time (given as identifier, not as string). GetType is called on an object at runtime. In both cases the result is an object of the type System.Type containing meta-information on a type.

Example where compile-time and run-time types are equal

string s = "hello";

Type t1 = typeof(string);
Type t2 = s.GetType();

t1 == t2 ==> true

Example where compile-time and run-time types are different

object obj = "hello";

Type t1 = typeof(object); // ==> object
Type t2 = obj.GetType();  // ==> string!

t1 == t2 ==> false

i.e., the compile time type (static type) of the variable obj is not the same as the runtime type of the object referenced by obj.

Testing types

If, however, you only want to know whether mycontrol is a TextBox then you can simply test

if (mycontrol is TextBox)

Note that this is not completely equivalent to

if (mycontrol.GetType() == typeof(TextBox))    

because mycontrol could have a type that is derived from TextBox. In that case the first comparison yields true and the second false! The first and easier variant is OK in most cases, since a control derived from TextBox inherits everything that TextBox has, probably adds more to it and is therefore assignment compatible to TextBox.

public class MySpecializedTextBox : TextBox
{
}

MySpecializedTextBox specialized = new MySpecializedTextBox();
if (specialized is TextBox)       ==> true

if (specialized.GetType() == typeof(TextBox))        ==> false

Casting

If you have the following test followed by a cast and T is nullable ...

if (obj is T) {
    T x = (T)obj; // The casting tests, whether obj is T again!
    ...
}

... you can change it to ...

T x = obj as T;
if (x != null) {
    ...
}

Testing whether a value is of a given type and casting (which involves this same test again) can both be time consuming for long inheritance chains. Using the as operator followed by a test for null is more performing.

Starting with C# 7.0 you can simplify the code by using pattern matching:

if (obj is T t) {
    // t is a variable of type T having a non-null value.
    ...
}

Btw.: this works for value types as well. Very handy for testing and unboxing. Note that you cannot test for nullable value types:

if (o is int? ni) ===> does NOT compile!

This is because either the value is null or it is an int. This works for int? o as well as for object o = new Nullable<int>(x);:

if (o is int i) ===> OK!

I like it, because it eliminates the need to access the Nullable<T>.Value property.

A shorter syntax for SWIFT 3

func listFilesFromDocumentsFolder() -> [String]?
{
    let fileMngr = FileManager.default;

    // Full path to documents directory
    let docs = fileMngr.urls(for: .documentDirectory, in: .userDomainMask)[0].path

    // List all contents of directory and return as [String] OR nil if failed
    return try? fileMngr.contentsOfDirectory(atPath:docs)
}

Usage example:

override func viewDidLoad()
{
    print(listFilesFromDocumentsFolder())
}

Tested on xCode 8.2.3 for iPhone 7 with iOS 10.2 & iPad with iOS 9.3

DECLARE @CodeNameString varchar(max)
SET @CodeNameString=''

SELECT @CodeNameString=@CodeNameString+CodeName FROM AccountCodes ORDER BY Sort
SELECT @CodeNameString

Here is a simple letter-range implementation:

Code

def letter_range(start, stop="{", step=1):
    """Yield a range of lowercase letters.""" 
    for ord_ in range(ord(start.lower()), ord(stop.lower()), step):
        yield chr(ord_)

Demo

list(letter_range("a", "f"))
# ['a', 'b', 'c', 'd', 'e']

list(letter_range("a", "f", step=2))
# ['a', 'c', 'e']

$("input[required]").attr("oninvalid", "this.setCustomValidity('Say Somthing!')");

this work if you move to previous or next field by mouse, but by enter key, this is not work !!!

I liked the Xembly syntax, but it is not a statically typed API. You can get this with XMLBeam:

// Declare a projection
public interface Projection {

    @XBWrite("/root/order/@id")
    Projection setID(int id);

    @XBWrite("/root/order")
    Projection setValue(String value);
}

public static void main(String[] args) {
    // create a projector
    XBProjector projector = new XBProjector();

    // use it to create a projection instance
    Projection projection = projector.projectEmptyDocument(Projection.class);

    // You get a fluent API, with java types in parameters 
    projection.setID(553).setValue("$140.00");

    // Use the projector again to do IO stuff or create an XML-string
    projector.toXMLString(projection);
}

My experience is that this works great even when the XML gets more complicated. You can just decouple the XML structure from your java code structure.

Use the RAISERROR function:

RAISERROR( 'This message will show up right away...',0,1) WITH NOWAIT

You shouldn't completely replace all your prints with raiserror. If you have a loop or large cursor somewhere just do it once or twice per iteration or even just every several iterations.

Also: I first learned about RAISERROR at this link, which I now consider the definitive source on SQL Server Error handling and definitely worth a read:
http://www.sommarskog.se/error-handling-I.html

In JavaScript first focus on the control and then select the control to display the cursor on texbox...

document.getElementById(frmObj.id).focus();
document.getElementById(frmObj.id).select();

or by using jQuery

$("#textboxID").focus();

function valid(data, array)
 local valid = {}
 for i = 1, #array do
  valid[array[i]] = true
 end
 if valid[data] then
  return false
 else
  return true
 end
end

Here's the function I use for checking if data is in an array.

The default values for minOccurs and maxOccurs are 1. Thus:

<xsd:element minOccurs="1" name="asdf"/>

cardinality is [1-1] Note: if you specify only minOccurs attribute, it can't be greater than 1, because the default value for maxOccurs is 1.

<xsd:element minOccurs="5" maxOccurs="2" name="asdf"/>

invalid

<xsd:element maxOccurs="2" name="asdf"/>

cardinality is [1-2] Note: if you specify only maxOccurs attribute, it can't be smaller than 1, because the default value for minOccurs is 1.

<xsd:element minOccurs="0" maxOccurs="0"/>

is a valid combination which makes the element prohibited.

Followup to lxs's answer: I noticed a problem where having both the zoom and --webkit-transform tags at the same time seems to confound Chrome (version 15.0.874.15) by doing a double-zoom sort of effect. I was able to work around the issue by replacing zoom with -ms-zoom (targeted only at IE), leaving Chrome to make use of just the --webkit-transform tag, and that cleared things up.

I recently used Spring Security 3.0 for this (combined with Wicket btw), and am quite happy with it. Here's a good thorough tutorial and documentation. Also take a look at this tutorial which gives a good explanation of the hashing/salting/decoding setup for Spring Security 2.

In comparisons it makes a difference if a scalar is a number of a string. And it is not always decidable. I can report a case where perl retrieved a float in "scientific" notation and used that same a few lines below in a comparison:

use strict;
....
next unless $line =~ /and your result is:\s*(.*)/;
my $val = $1;
if ($val < 0.001) {
   print "this is small\n";
}

And here $val was not interpreted as numeric for e.g. "2e-77" retrieved from $line. Adding 0 (or 0.0 for good ole C programmers) helped.

I had the same problem, check the installed jre used by Maven in your Run Configuration...

In your case, I think that the maven-compiler-plugin:jar:2.3.2 needs a jdk1.6

To do this : Run Configuration > YOUR_MAVEN_BUILD > JRE > Alternate JRE

Hope this helps.

I run at this when I tried to add privileges to performance_schema, which is mysql bug http://bugs.mysql.com/bug.php?id=44898 (workaround to add --single-transaction).

This also happened to me when a PercentageRelativeLayout https://developer.android.com/reference/android/support/percent/PercentRelativeLayout.html was used and the build was targeting Android 0 = 26. PercentageRelativeLayout layout is obsolete starting from Android O and obviously sometime was changed in the resource generation. Replacing the layout with a ConstraintLayout or just a RelativeLayout solved it.

The fetch mode only says that the association must be fetched. If you want to add restrictions on an associated entity, you must create an alias, or a subcriteria. I generally prefer using aliases, but YMMV:

Criteria c = session.createCriteria(Dokument.class, "dokument");
c.createAlias("dokument.role", "role"); // inner join by default
c.createAlias("role.contact", "contact");
c.add(Restrictions.eq("contact.lastName", "Test"));
return c.list();

This is of course well explained in the Hibernate reference manual, and the javadoc for Criteria even has examples. Read the documentation: it has plenty of useful information.

The TraceContext object in ASP.NET writes to the DefaultTraceListener which outputs to the host process’ standard output. Rather than using Console.Write(), if you use Trace.Write, output will go to the standard output of the process.

You could use the System.Diagnostics.Process object to get the ASP.NET process for your site and monitor standard output using the OutputDataRecieved event.

As others have said the appropriate way to add git aliases is in your global .gitconfig file either by editing ~/.gitconfig or by using the git config --global alias.<alias> <git-command> command

Below is a copy of the alias section of my ~/.gitconfig file:

[alias]
    st = status
    ci = commit
    co = checkout
    br = branch
    unstage = reset HEAD --
    last = log -1 HEAD

Also, if you're using bash, I would recommend setting up bash completion by copying git-completion.bash to your home directory and sourcing it from your ~/.bashrc. (I believe I learned about this from the Pro Git online book.) On Mac OS X, I accomplished this with the following commands:

# Copy git-completion.bash to home directory
cp usr/local/git/contrib/completion/git-completion.bash ~/

# Add the following lines to ~/.bashrc
if [ -x /usr/local/git/bin/git ]; then
    source ~/.git-completion.bash
fi

Note: The bash completion will work not only for the standard git commands but also for your git aliases.

Finally, to really cut down on the keystrokes, I added the following to my ~/.bash_aliases file, which is sourced from ~/.bashrc:

alias gst='git status'
alias gl='git pull'
alias gp='git push'
alias gd='git diff | mate'
alias gau='git add --update'
alias gc='git commit -v'
alias gca='git commit -v -a'
alias gb='git branch'
alias gba='git branch -a'
alias gco='git checkout'
alias gcob='git checkout -b'
alias gcot='git checkout -t'
alias gcotb='git checkout --track -b'
alias glog='git log'
alias glogp='git log --pretty=format:"%h %s" --graph'

The following will cover all browsers worth covering:

text-shadow: 0 0 2px #fff; /* Firefox 3.5+, Opera 9+, Safari 1+, Chrome, IE10 */
filter: progid:DXImageTransform.Microsoft.Glow(Color=#ffffff,Strength=1); /* IE<10 */

For copying one file to another directory overwriting without any prompt i ended up using the simply COPY command:

copy /Y ".\mySourceFile.txt" "..\target\myDestinationFile.txt"

sprintf('%.2f', number) is a cryptic, but very powerful way of formatting numbers. The result is always a string, but since you're rounding I assume you're doing it for presentation purposes anyway. sprintf can format any number almost any way you like, and lots more.

Full sprintf documentation: http://www.ruby-doc.org/core-2.0.0/Kernel.html#method-i-sprintf

Check out jQuery.floatThead (demos available) which is very cool, can work with DataTables too, and can even work inside an overflow: auto container.

Strings in C are represented as arrays of characters.

char *p = "String";

You are declaring a pointer that points to a string stored some where in your program (modifying this string is undefined behavior) according to the C programming language 2 ed.

char p2[] = "String";

You are declaring an array of char initialized with the string "String" leaving to the compiler the job to count the size of the array.

char p3[5] = "String";

You are declaring an array of size 5 and initializing it with "String". This is an error be cause "String" don't fit in 5 elements.

char p3[7] = "String"; is the correct declaration ('\0' is the terminating character in c strings).

With mysql v5.7.20, here is how I was able to get the row count from a table using PHP v7.0.22:

$query = "select count(*) from bigtable";
$qresult = mysqli_query($this->conn, $query);
$row = mysqli_fetch_assoc($qresult);
$count = $row["count(*)"];
echo $count;

The third line will return a structure that looks like this:

array(1) {
   ["count(*)"]=>string(4) "1570"
}

In which case the ending echo statement will return:

1570

You Can Set Variables In The Blade Templating Engine The Following Ways:

1. General PHP Block
Setting Variable: <?php $hello = "Hello World!"; ?>
Output: {{$hello}}

2. Blade PHP Block
Setting Variable: @php $hello = "Hello World!"; @endphp
Output: {{$hello}}

Just to add some additional info to demonstrate how much difference the member initialization list can mak. In the leetcode 303 Range Sum Query - Immutable, https://leetcode.com/problems/range-sum-query-immutable/, where you need to construct and initialize to zero a vector with certain size. Here is two different implementation and speed comparison.

Without member initialization list, to get AC it cost me about 212 ms.

class NumArray {
public:
vector<int> preSum;
NumArray(vector<int> nums) {
    preSum = vector<int>(nums.size()+1, 0);
    int ps = 0;
    for (int i = 0; i < nums.size(); i++)
    {
        ps += nums[i];
        preSum[i+1] = ps;
    }
}

int sumRange(int i, int j) {
    return preSum[j+1] - preSum[i];
}
};

Now using member initialization list, the time to get AC is about 108 ms. With this simple example, it is quite obvious that, member initialization list is way more efficient. All the measurement is from the running time from LC.

class NumArray {
public:
vector<int> preSum;
NumArray(vector<int> nums) : preSum(nums.size()+1, 0) { 
    int ps = 0;
    for (int i = 0; i < nums.size(); i++)
    {
        ps += nums[i];
        preSum[i+1] = ps;
    }
}

int sumRange(int i, int j) {
    return preSum[j+1] - preSum[i];
}
};

This alternative seems the most appropriate.

$('input[type="file"]').change(function(e){
        var fileName = e.target.files[0].name;
        alert('The file "' + fileName +  '" has been selected.');
});

I don't think you could change the style of browsers' default alert boxes.

You need to create your own or use a simple and customizable library like xdialog. Following is a example to customize the alert box. More demos can be found here.

function show_alert() {_x000D_
    xdialog.alert("Hello! I am an alert box!");_x000D_

I believe you are presenting a false dichotomy. These are not the only two options.

I agree with Mr. D4V360 who suggested that, even though you are using the anchor tag, you do not truly have an anchor here. All you have is a special section of a document that should behave slightly different. A <span> tag is far more appropriate.

I have Jquery and Angular from bower. Bower installed them in

I had the same problems:java.lang.NoClassDefFoundError: Could not initialize class com.xxx.HttpUtils

it is the environment problem.That means the properties in application.yml is incorrect or empty!

Last I checked, there isn't a command line command to connect to a URL from the MS command line. Try wget for Windows:

or URL2File:

In Linux, you can use "wget".

Alternatively, you can try VBScript. They are like command line programs, but they are scripts interpreted by the wscript.exe scripts host. Here is an example of downloading a file using VBS:

You shouldn't edit any code manually jetify should do this job for you, if you are running/building from cli using react-native you dont' need to do anything but if you are running/building Andriod studio you need to run jetify as pre-build, here is how can you automate this:

1- From the above menu go to edit configurations:

2- Add the bottom of the screen you will find before launch click on the plus and choose Run External Tool

2- Fill the following information, note that the working directory is your project root directory (not the android directory):

3- Make sure this run before anything else, in the end, your configuration should look something like this:

I also experienced the same thing. I found out that my favicon.ico had not been processed as a legitimate shortcut icon. I understand that favicons must be scaled to 16x16 and follow the Microsoft Icon format.

Your problem seems unclear. You say you want to remove "a character from a certain position" then go on to say you want to remove a particular character.

If you only need to remove the first character you would do:

s = ":dfa:sif:e"
fixed = s[1:]

If you want to remove a character at a particular position, you would do:

s = ":dfa:sif:e"
fixed = s[0:pos]+s[pos+1:]

If you need to remove a particular character, say ':', the first time it is encountered in a string then you would do:

s = ":dfa:sif:e"
fixed = ''.join(s.split(':', 1))

The methods you're calling on the Boolean class don't check whether the string contains a valid boolean value, but they return the boolean value that represents the contents of the string: put "true" in string, they return true, put "false" in string, they return false.

You can surely use these methods, however, to check for valid boolean values, as I'd expect them to throw an exception if the string contains "hello" or something not boolean.

Wrap that in a Method ContainsBoolString and you're go.

EDIT
By the way, in C# there are methods like bool Int32.TryParse(string x, out int i) that perform the check whether the content can be parsed and then return the parsed result.

int i;
if (Int32.TryParse("Hello", out i))
  // Hello is an int and its value is in i
else
  // Hello is not an int

Benchmarks indicate they are way faster than the following:

int i;
try
{
   i = Int32.Parse("Hello");
   // Hello is an int and its value is in i
}
catch
{
   // Hello is not an int
}

Maybe there are similar methods in Java? It's been a while since I've used Java...

This:

document.getElementById('myField').onblur();

works because your element (the <input>) has an attribute called "onblur" whose value is a function. Thus, you can call it. You're not telling the browser to simulate the actual "blur" event, however; there's no event object created, for example.

Elements do not have a "blur" attribute (or "method" or whatever), so that's why the first thing doesn't work.

The easiest way I have tested just add a <br> as in the following:

<div class="col-sm-6">
    <br><h3><p class="text-center">Some Text</p></h3>
</div>

The only problem is that a extra line break (generated by that <br>) is generated when the screen gets smaller and it stacks. But it is quick and simple.

I had the same problem running Ubuntu 18.04. I tried multiple solutions but my device (OnePlus 5T) was always unauthorized.

   The idVendor of my device (OnePlus) is not listed. To get it, just connect your device and use lsusb:

   Bus 003 Device 008: ID 2a70:4ee7

   In this example, 2a70 is the idVendor.

2. Remove existing adb keys on Ubuntu:

   rm -v ~/.android/adbkey* ~/.android/adbkey ~/.android/adbkey.pub

3. 'Revoke USB debugging authorizations' on your device configuration (developer options).

4. Finally, restart the adb server to create a new key:

   sudo adb kill-server sudo adb devices

After that, I got the authorization prompt on my device and I authorized it.

Using HTTP Request verb such as GET, POST, DELETE, PUT etc... enables you to build RESTful web applications. Read about it here: http://en.wikipedia.org/wiki/Representational_state_transfer

The easiest way to see benefits from this is to look at this example. Every MVC framework has a Router/Dispatcher that maps URL-s to actionControllers. So URL like this: /blog/article/1 would invoke blogController::articleAction($id); Now this Router is only aware of the URL or /blog/article/1/

But if that Router would be aware of whole HTTP Request object instead of just URL, he could have access HTTP Request verb (GET, POST, PUT, DELETE...), and many other useful stuff about current HTTP Request.

That would enable you to configure application so it can accept the same URL and map it to different actionControllers depending on the HTTP Request verb.

For example:

if you want to retrive article 1 you can do this:

GET /blog/article/1 HTTP/1.1

but if you want to delete article 1 you will do this:

DELETE /blog/article/1 HTTP/1.1

Notice that both HTTP Requests have the same URI, /blog/article/1, the only difference is the HTTP Request verb. And based on that verb your router can call different actionController. This enables you to build neat URL-s.

Read this two articles, they might help you:

Symfony 2 - HTTP Fundamentals

Symfony 2 - Routing

These articles are about Symfony 2 framework, but they can help you to figure out how does HTTP Requests and Responses work.

Hope this helps!

You can use LOG such as :

Log.e(String, String) (error)
Log.w(String, String) (warning)
Log.i(String, String) (information)
Log.d(String, String) (debug)
Log.v(String, String) (verbose)

example code:

private static final String TAG = "MyActivity";
...
Log.i(TAG, "MyClass.getView() — get item number " + position);

Before applying

runAllManagedModulesForAllRequests="true"/>

consider the link below that suggests a less drastic alternative. In the post the author offers the following alteration to the local web.config:

  <system.webServer>
    <modules>
    <remove name="UrlRoutingModule-4.0" />
    <add name="UrlRoutingModule-4.0" type="System.Web.Routing.UrlRoutingModule" preCondition="" />
    </modules>

In Laravel 6, by default the logs are in:

storage/logs/laravel.log

This worked for me:

1. Add the directory which contains the editor's executable to your PATH variable. (E.g. "C:\Program Files\Sublime Text 3\")
2. Reboot your computer.
3. Change the core.editor global Git variable to the name of the editor executable without the extension '.exe' (e.g. git config --global core.editor sublime_text)

That's it!

NOTE: Sublime Text 3 is the editor I used for this example.

Thanks for the replies.
What I did was,
1. I install meinberg ntp software application on windows 7 pc. (softros ntp server is also possible.)
2. change raspberry pi ntp.conf file (for auto update date and time)

server xxx.xxx.xxx.xxx iburst
server 1.debian.pool.ntp.org iburst
server 2.debian.pool.ntp.org iburst
server 3.debian.pool.ntp.org iburst

3. If you want to make sure that date and time update at startup run this python script in rpi,

import os

try:
    client = ntplib.NTPClient()
    response = client.request('xxx.xxx.xxx.xxx', version=4)
    print "===================================="
    print "Offset : "+str(response.offset)
    print "Version : "+str(response.version)
    print "Date Time : "+str(ctime(response.tx_time))
    print "Leap : "+str(ntplib.leap_to_text(response.leap))
    print "Root Delay : "+str(response.root_delay)
    print "Ref Id : "+str(ntplib.ref_id_to_text(response.ref_id))
    os.system("sudo date -s '"+str(ctime(response.tx_time))+"'")
    print "===================================="
except:
    os.system("sudo date")
    print "NTP Server Down Date Time NOT Set At The Startup"
    pass

I found more info in raspberry pi forum.

The JDK 8 HotSpot JVM is now using native memory for the representation of class metadata and is called Metaspace.

The permanent generation has been removed. The PermSize and MaxPermSize are ignored and a warning is issued if they are present on the command line.

An improvement to the most useful answer here:

1] No need to restart the mysql server
2] Security concern for a MySQL server connected to a network

There is no need to restart the MySQL server.

use FLUSH PRIVILEGES; after the update mysql.user statement for password change.

The FLUSH statement tells the server to reload the grant tables into memory so that it notices the password change.

The --skip-grant-options enables anyone to connect without a password and with all privileges. Because this is insecure, you might want to

use --skip-grant-tables in conjunction with --skip-networking to prevent remote clients from connecting.

You may be used to MySQL's syntax: Microsoft SQL @ is the same as the MySQL's ?

//general Syntax

       set<int>::iterator ii = find(set1.begin(),set1.end(),"element to be searched");

/* in below code i am trying to find element 4 in and int set if it is present or not*/

set<int>::iterator ii = find(set1.begin(),set1.end(),4);
 if(ii!=set1.end())
 {
    cout<<"element found";
    set1.erase(ii);// in case you want to erase that element from set.
 }

This location has, once again, changed, if using Swift, use this to find out where the folder is (this is copied from the AppDelegate.swift file that Apple creates for you so if it doesn't work on your machine, search in that file for the right syntax, this works on mine using Xcode 6.1 and iOS 8 simulator):

let urls = NSFileManager.defaultManager().URLsForDirectory(.DocumentDirectory, inDomains: .UserDomainMask)
println("Possible sqlite file: \(urls)")

This way work for me:

  @Override
protected void onCreate(Bundle savedInstanceState) {
    setTheme(GApplication.getInstance().getTheme());
    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_main);
}

Then you want to change a new theme:

GApplication.getInstance().setTheme(R.style.LightTheme);
recreate();

You need to query the data dictionary, specifically the USER_CONS_COLUMNS view to see the table columns and corresponding constraints:

SELECT *
  FROM user_cons_columns
 WHERE table_name = '<your table name>';

FYI, unless you specifically created your table with a lower case name (using double quotes) then the table name will be defaulted to upper case so ensure it is so in your query.

If you then wish to see more information about the constraint itself query the USER_CONSTRAINTS view:

SELECT *
  FROM user_constraints
 WHERE table_name = '<your table name>'
   AND constraint_name = '<your constraint name>';

If the table is held in a schema that is not your default schema then you might need to replace the views with:

all_cons_columns

and

all_constraints

adding to the where clause:

   AND owner = '<schema owner of the table>'

Update: Using DateTimeFormat, introduced in java 8:

The idea is to define two formats: one for the input format, and one for the output format. Parse with the input formatter, then format with the output formatter.

Your input format looks quite standard, except the trailing Z. Anyway, let's deal with this: "yyyy-MM-dd'T'HH:mm:ss.SSS'Z'". The trailing 'Z' is the interesting part. Usually there's time zone data here, like -0700. So the pattern would be ...Z, i.e. without apostrophes.

The output format is way more simple: "dd-MM-yyyy". Mind the small y -s.

Here is the example code:

DateTimeFormatter inputFormatter = DateTimeFormatter.ofPattern("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'", Locale.ENGLISH);
DateTimeFormatter outputFormatter = DateTimeFormatter.ofPattern("dd-MM-yyy", Locale.ENGLISH);
LocalDate date = LocalDate.parse("2018-04-10T04:00:00.000Z", inputFormatter);
String formattedDate = outputFormatter.format(date);
System.out.println(formattedDate); // prints 10-04-2018

Original answer - with old API SimpleDateFormat

SimpleDateFormat inputFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'");
SimpleDateFormat outputFormat = new SimpleDateFormat("dd-MM-yyyy");
Date date = inputFormat.parse("2018-04-10T04:00:00.000Z");
String formattedDate = outputFormat.format(date);
System.out.println(formattedDate); // prints 10-04-2018

You could just use: {in and out function callback}

$(".result").hover(function () {
    $(this).toggleClass("result_hover");
 });

For your example, better will be to use CSS pseudo class :hover: {no js/jquery needed}

.result {
    height: 72px;
    width: 100%;
    border: 1px solid #000;
  }
  .result:hover {
    background-color: #000;
  }

The Math.round function is overloaded When it receives a float value, it will give you an int. For example this would work.

int a=Math.round(1.7f);

When it receives a double value, it will give you a long, therefore you have to typecast it to int.

int a=(int)Math.round(1.7);

This is done to prevent loss of precision. Your double value is 64bit, but then your int variable can only store 32bit so it just converts it to long, which is 64bit but you can typecast it to 32bit as explained above.

Goto Advanced tab----> data type of column---> Here change data type from DT_STR to DT_TEXT and column width 255. Now you can check it will work perfectly.

1. Right Click on Drawable Folder and Create new File
2. Name the file according to you and add the extension as .xml.
3. Add the following code in the file

  <?xml version="1.0" encoding="utf-8"?>
  <shape xmlns:android="http://schemas.android.com/apk/res/android"
      android:shape="rectangle">
      <corners android:radius="5dp" />
      <stroke android:width="1dp"  />
      <solid android:color="#1e90ff" />
  </shape>

4. Add the line where you want the rounded edge android:background="@drawable/corner"

This is how I did it. This makes the images in the slideshow take up the full screen if it´s aspect ratio allows it, othervice it scales down.

.carousel {
    height: 100vh;
    width: 100%;
    overflow:hidden;
}
.carousel .carousel-inner {
    height:100%;    
}

To allways get a full screen slideshow, no matter screen aspect ratio, you can also use object-fit: (doesn´t work in IE or Edge)

.carousel .carousel-inner img {
    display:block;
    object-fit: cover;
}

Another way you can achieve a pause between animations is to apply a second animation that hides the element for the amount of delay you want. This has the benefit of allowing you to use a CSS easing function like you would normally.

.star {
  animation: shooting-star 1000ms ease-in-out infinite,
    delay-animation 2000ms linear infinite;
}

@keyframes shooting-star {
  0% {
    transform: translate(0, 0) rotate(45deg);
  }

  100% {
    transform: translate(300px, 300px) rotate(45deg);
  }
}

@keyframes delay-animation {
  0% {
    opacity: 1;
  }
  50% {
    opacity: 1;
  }
  50.01% {
    opacity: 0;
  }
  100% {
    opacity: 0;
  }
}

This only works if you want the delay to be a multiple of the animation duration. I used this to make a shower of shooting stars appear more random: https://codepen.io/ericdjohnson/pen/GRpOgVO

To get a JSONObject or JSONArray from a String I've created this class:

public static class JSON {

     public Object obj = null;
     public boolean isJsonArray = false;

     JSON(Object obj, boolean isJsonArray){
         this.obj = obj;
         this.isJsonArray = isJsonArray;
     }
}

Here to get the JSON:

public static JSON fromStringToJSON(String jsonString){

    boolean isJsonArray = false;
    Object obj = null;

    try {
        JSONArray jsonArray = new JSONArray(jsonString);
        Log.d("JSON", jsonArray.toString());
        obj = jsonArray;
        isJsonArray = true;
    }
    catch (Throwable t) {
        Log.e("JSON", "Malformed JSON: \"" + jsonString + "\"");
    }

    if (object == null) {
        try {
            JSONObject jsonObject = new JSONObject(jsonString);
            Log.d("JSON", jsonObject.toString());
            obj = jsonObject;
            isJsonArray = false;
        } catch (Throwable t) {
            Log.e("JSON", "Malformed JSON: \"" + jsonString + "\"");
        }
    }

    return new JSON(obj, isJsonArray);
}

Example:

JSON json = fromStringToJSON("{\"message\":\"ciao\"}");
if (json.obj != null) {

    // If the String is a JSON array
    if (json.isJsonArray) {
        JSONArray jsonArray = (JSONArray) json.obj;
    }
    // If it's a JSON object
    else {
        JSONObject jsonObject = (JSONObject) json.obj;
    }
}

Select Product from formula bar in your answer cell.

Select cells you want to multiply.

select * into #temptable from tablename where 1<>1

Your for loop has no loop body:

elif option == 2:
    print "please enter a number"
    for x in range(x, 1, 1):
elif option == 0:

Actually, the whole if option == 1: block has indentation problems. elif option == 2: should be at the same level as the if statement.

You may want to also look into using Task instead of background workers.

The easiest way to do this is in your example is Task.Run(InitializationThread);.

There are several benefits to using tasks instead of background workers. For example, the new async/await features in .net 4.5 use Task for threading. Here is some documentation about Task https://docs.microsoft.com/en-us/dotnet/api/system.threading.tasks.task

The question is already answered but these were not working in my case which is alpine Linux based OS so maybe this helps someone else.

I was also getting same error

gyp ERR! configure error 
gyp ERR! stack Error: Can't find Python executable "python", you can set the PYTHON env variable.

So fix by single line just add this if you are working in Dockerfile or install it in OS

apk add --no-cache python nodejs

in ubuntu

sudo apt-get install python3.6

Note: Node version:8

While not directly related to the question's environment, just for the curiosity, I did the same test on .NET Core 2.1, x64, release mode.

Here is the interesting result, confirming similar phonomena (other way around) happening over the dark side of the force. Code:

static void Main(string[] args)
{
    Stopwatch watch = new Stopwatch();

    Console.WriteLine("2 * (i * i)");

    for (int a = 0; a < 10; a++)
    {
        int n = 0;

        watch.Restart();

        for (int i = 0; i < 1000000000; i++)
        {
            n += 2 * (i * i);
        }

        watch.Stop();

        Console.WriteLine($"result:{n}, {watch.ElapsedMilliseconds} ms");
    }

    Console.WriteLine();
    Console.WriteLine("2 * i * i");

    for (int a = 0; a < 10; a++)
    {
        int n = 0;

        watch.Restart();

        for (int i = 0; i < 1000000000; i++)
        {
            n += 2 * i * i;
        }

        watch.Stop();

        Console.WriteLine($"result:{n}, {watch.ElapsedMilliseconds}ms");
    }
}

Result:

2 * (i * i)

• result:119860736, 438 ms
• result:119860736, 433 ms
• result:119860736, 437 ms
• result:119860736, 435 ms
• result:119860736, 436 ms
• result:119860736, 435 ms
• result:119860736, 435 ms
• result:119860736, 439 ms
• result:119860736, 436 ms
• result:119860736, 437 ms

2 * i * i

• result:119860736, 417 ms
• result:119860736, 417 ms
• result:119860736, 417 ms

• result:119860736, 418 ms

You can override the constructor. Something like:

private class MyAsyncTask extends AsyncTask<Void, Void, Void> {

    public MyAsyncTask(boolean showLoading) {
        super();
        // do stuff
    }

    // doInBackground() et al.
}

Then, when calling the task, do something like:

new MyAsyncTask(true).execute(maybe_other_params);

Edit: this is more useful than creating member variables because it simplifies the task invocation. Compare the code above with:

MyAsyncTask task = new MyAsyncTask();
task.showLoading = false;
task.execute();

Can also be called as

@Html.Partial("_PartialView", (ModelClass)View.Data)

Assuming you want to add this path for all users on the system, add the following line to your /etc/profile.d/play.sh (and possibly play.csh, etc):

PATH=$PATH:/home/me/play
export PATH

you can use mongo query like this yearMonthDayhms: { $dateToString: { format: "%Y-%m-%d-%H-%M-%S", date: {$subtract:["$cdt",14400000]}}}

HourMinute: { $dateToString: { format: "%H-%M-%S", date: {$subtract:["$cdt",14400000]}}}

And in PostgreSQL:

SELECT pg_size_pretty(pg_relation_size('tablename'));

If you are having 112 columns in one single table and you would like to insert data from source table, you could do as

create table employees as select * from source_employees where employee_id=100;

Or from sqlplus do as

copy from source_schema/password insert employees using select * from 
source_employees where employee_id=100;

I've investigated this issue, referring to the LayoutInflater docs and setting up a small sample demonstration project. The following tutorials shows how to dynamically populate a layout using LayoutInflater.

Before we get started see what LayoutInflater.inflate() parameters look like:

• resource: ID for an XML layout resource to load (e.g., R.layout.main_page)
• root: Optional view to be the parent of the generated hierarchy (if attachToRoot is true), or else simply an object that provides a set of LayoutParams values for root of the returned hierarchy (if attachToRoot is false.)

• attachToRoot: Whether the inflated hierarchy should be attached to the root parameter? If false, root is only used to create the correct subclass of LayoutParams for the root view in the XML.

• Returns: The root View of the inflated hierarchy. If root was supplied and attachToRoot is true, this is root; otherwise it is the root of the inflated XML file.

Now for the sample layout and code.

Main layout (main.xml):

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/container"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
</LinearLayout>

Added into this container is a separate TextView, visible as small red square if layout parameters are successfully applied from XML (red.xml):

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="25dp"
    android:layout_height="25dp"
    android:background="#ff0000"
    android:text="red" />

Now LayoutInflater is used with several variations of call parameters

public class InflaterTest extends Activity {

    private View view;

    @Override
    public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);

      setContentView(R.layout.main);
      ViewGroup parent = (ViewGroup) findViewById(R.id.container);

      // result: layout_height=wrap_content layout_width=match_parent
      view = LayoutInflater.from(this).inflate(R.layout.red, null);
      parent.addView(view);

      // result: layout_height=100 layout_width=100
      view = LayoutInflater.from(this).inflate(R.layout.red, null);
      parent.addView(view, 100, 100);

      // result: layout_height=25dp layout_width=25dp
      // view=textView due to attachRoot=false
      view = LayoutInflater.from(this).inflate(R.layout.red, parent, false);
      parent.addView(view);

      // result: layout_height=25dp layout_width=25dp 
      // parent.addView not necessary as this is already done by attachRoot=true
      // view=root due to parent supplied as hierarchy root and attachRoot=true
      view = LayoutInflater.from(this).inflate(R.layout.red, parent, true);
    }
}

The actual results of the parameter variations are documented in the code.

SYNOPSIS: Calling LayoutInflater without specifying root leads to inflate call ignoring the layout parameters from the XML. Calling inflate with root not equal null and attachRoot=true does load the layout parameters, but returns the root object again, which prevents further layout changes to the loaded object (unless you can find it using findViewById()). The calling convention you most likely would like to use is therefore this one:

loadedView = LayoutInflater.from(context)
                .inflate(R.layout.layout_to_load, parent, false);

To help with layout issues, the Layout Inspector is highly recommended.

Copy-paste below jQuery <script> and stylesheet <link> into your <head> to make sure you're loading all necessary files.

It's important that your JQuery .js file is above .css stylesheet

Simply paste the following line to test

<script src="//ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script src="//netdna.bootstrapcdn.com/bootstrap/4.3.1/js/bootstrap.min.js"></script>
<link rel="stylesheet" type="text/css" href="//netdna.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css">

The problem occurs mostly with loading of jQuery script, make sure you add references correctly.

Now test

Still if it doesn't work, check bootstrap website they've a sample implementation.

https://getbootstrap.com/docs/4.3/components/navbar/#supported-content

From Apache Commons library:

import org.apache.commons.lang3.StringUtils

Use:

StringUtils.join(slist, ',');

Another similar question and answer here

I was facing the same problem because some of the images are grey scale images in my data set, so i solve my problem by doing this

    from PIL import Image
    img = Image.open('my_image.jpg').convert('RGB')
    # a line from my program
    positive_images_array = np.array([np.array(Image.open(img).convert('RGB').resize((150, 150), Image.ANTIALIAS)) for img in images_in_yes_directory])

1. Code Works For older IE

2. Tried For Many Colors

   <hr color="black">
   <hr color="blue">
   

For your specific case, the body is for creating a variable, and switching to IEnumerable will force all the operations to be processed on client-side, I propose the following solution.

Obj[] myArray = objects
.Select(o => new
{
    SomeLocalVar = o.someVar, // You can even use any LINQ statement here
    Info = o,
}).Select(o => new Obj()
{
    Var1 = o.SomeLocalVar,
    Var2 = o.Info.var2,
    Var3 = o.SomeLocalVar.SubValue1,
    Var4 = o.SomeLocalVar.SubValue2,
}).ToArray();

Edit: Rename for C# Coding Convention

I've been in same situation as well, and My case was because of the Korean letter in the path...

After I remove Korean letters from the folder name, it works.

OR put

[#-*- coding:utf-8 -*-]

(except [ ] at the edge)

or something like that in the first line to make python understand Korean or your language or etc. then it will work even if there is some Koreans in the path in my case.

So the things is, it seems like there is something about path or the letter. People who answered are saying similar things. Hope you guys solve it!

I was receiving the same error message after switching to a new theme in Wordpress. PHP was running version 5.3 so I switched to 7.2. That fixed the issue.

First of all you need to remove the data-toggle attribute. We will use some JQuery, so make sure you include it.

  <ul class='nav nav-tabs'>
    <li class='active'><a href='#home'>Home</a></li>
    <li><a href='#menu1'>Menu 1</a></li>
    <li><a href='#menu2'>Menu 2</a></li>
    <li><a href='#menu3'>Menu 3</a></li>
  </ul>

  <div class='tab-content'>
    <div id='home' class='tab-pane fade in active'>
      <h3>HOME</h3>
    <div id='menu1' class='tab-pane fade'>
      <h3>Menu 1</h3>
    </div>
    <div id='menu2' class='tab-pane fade'>
      <h3>Menu 2</h3>
    </div>
    <div id='menu3' class='tab-pane fade'>
      <h3>Menu 3</h3>
    </div>
  </div>
</div>

<script>
$(document).ready(function(){
// Handling data-toggle manually
    $('.nav-tabs a').click(function(){
        $(this).tab('show');
    });
// The on tab shown event
    $('.nav-tabs a').on('shown.bs.tab', function (e) {
        alert('Hello from the other siiiiiide!');
        var current_tab = e.target;
        var previous_tab = e.relatedTarget;
    });
});
</script>

No need to create a GD resource, as someone else suggested.

$input = 'http://images.websnapr.com/?size=size&key=Y64Q44QLt12u&url=http://google.com';
$output = 'google.com.jpg';
file_put_contents($output, file_get_contents($input));

Note: this solution only works if you're setup to allow fopen access to URLs. If the solution above doesn't work, you'll have to use cURL.

SQLFiddle will let you test out your queries, while it doesn't explicitly correct syntax etc. per se it does let you play around with the script and will definitely let you know if things are working or not.

If you are interested in writing a compiler for a functional language (rather than a procedural one) Simon Peyton-Jones and David Lester's "Implementing functional languages: a tutorial" is an excellent guide.

The conceptual basics of how functional evaluation works is guided by examples in a simple but powerful functional language called "Core". Additionally, each part of the Core language compiler is explained with code examples in Miranda (a pure functional language very similar to Haskell).

Several different types of compilers are described but even if you only follow the so-called template compiler for Core you will have an excellent understanding of what makes functional programming tick.

This is a good description of its uses and shortcomings. You essentially use it whenever you need to do fast low-level I/O. If you were going to implement a TCP/IP protocol or if you were writing a database (DBMS) this class would come in handy.

Simply call .off() right before you call .on().

This will remove all event handlers:

$(element).off().on('click', function() {
// function body
});

To only remove registered 'click' event handlers:

$(element).off('click').on('click', function() {
// function body
});

Unless you're trying to upload the file using ajax, just submit the form to /upload/image.

<form enctype="multipart/form-data" action="/upload/image" method="post">
    <input id="image-file" type="file" />
</form>

If you do want to upload the image in the background (e.g. without submitting the whole form), you can use ajax:

• Asynchronous file upload (AJAX file upload) using jsp and javascript
• jQuery Ajax File Upload
• Ajax using file upload

you could also do show columns in $table or see Hive, how do I retrieve all the database's tables columns for access to hive metadata

A well-explained answer is already given by @mkobit, but I will add a big picture of the range key and hash key.

In a simple words range + hash key = composite primary key CoreComponents of Dynamodb

A primary key is consists of a hash key and an optional range key. Hash key is used to select the DynamoDB partition. Partitions are parts of the table data. Range keys are used to sort the items in the partition, if they exist.

So both have a different purpose and together help to do complex query. In the above example hashkey1 can have multiple n-range. Another example of range and hashkey is game, userA(hashkey) can play Ngame(range)

The Music table described in Tables, Items, and Attributes is an example of a table with a composite primary key (Artist and SongTitle). You can access any item in the Music table directly, if you provide the Artist and SongTitle values for that item.

A composite primary key gives you additional flexibility when querying data. For example, if you provide only the value for Artist, DynamoDB retrieves all of the songs by that artist. To retrieve only a subset of songs by a particular artist, you can provide a value for Artist along with a range of values for SongTitle.

This can also be done with the Image class of the PIL library:

from PIL import Image
import numpy as np

im_frame = Image.open(path_to_file + 'file.png')
np_frame = np.array(im_frame.getdata())

Note: The .getdata() might not be needed - np.array(im_frame) should also work

Actually, RFC 2965, the document that defines how cookies work, specifies that there should be no maximum length of a cookie's key or value size, and encourages implementations to support arbitrarily large cookies. Each browser's implementation maximum will necessarily be different, so consult individual browser documentation.

See section 5.3, "Implementation Limits", in the RFC.

I dug deeper into this and found the best solutions are here.

http://blog.notdot.net/2010/07/Getting-unicode-right-in-Python

In my case I solved "UnicodeEncodeError: 'charmap' codec can't encode character "

original code:

print("Process lines, file_name command_line %s\n"% command_line))

New code:

print("Process lines, file_name command_line %s\n"% command_line.encode('utf-8'))  

I took a look at how YouTube solves it on their homepage and simplified it:

.multine-ellipsis {
  -webkit-box-orient: vertical;
  display: -webkit-box;
  -webkit-line-clamp: 2;
  overflow: hidden;
  text-overflow: ellipsis;
  white-space: normal;
}

This will allow 2 lines of code and then append an ellipsis.

I'm just getting my feet wet with angular, but I found this great tutorial.
Here's a working plunk I put together with credit to Scott Allen and the above tutorial. Click search to display the sortable table.

For each column header you need to make it clickable - ng-click on a link will work. This will set the sortName of the column to sort.

<th>
     <a href="#" ng-click="sortName='name'; sortReverse = !sortReverse">
          <span ng-show="sortName == 'name' && sortReverse" class="glyphicon glyphicon-triangle-bottom"></span>
          <span ng-show="sortName == 'name' && !sortReverse" class="glyphicon glyphicon-triangle-top"></span>
           Name
     </a>
</th>

Then, in the table body you can pipe in that sortName in the orderBy filter orderBy:sortName:sortReverse

<tr ng-repeat="repo in repos | orderBy:sortName:sortReverse | filter:searchRepos">
     <td>{{repo.name}}</td>
     <td class="tag tag-primary">{{repo.stargazers_count | number}}</td>
     <td>{{repo.language}}</td>
</tr>

This is bit out of context but in case you are here because you want to tag a specific commit like i do

Here's a command to do that :-

Example:

git tag -a v1.0 7cceb02 -m "Your message here"

Where 7cceb02 is the beginning part of the commit id.

You can then push the tag using git push origin v1.0.

You can do git log to show all the commit id's in your current branch.

use 127.0.0.1 instead of localhost

This is surely an encoding problem. You have a different encoding in your database and in your website and this fact is the cause of the problem. Also if you ran that command you have to change the records that are already in your tables to convert those character in UTF-8.

Update: Based on your last comment, the core of the problem is that you have a database and a data source (the CSV file) which use different encoding. Hence you can convert your database in UTF-8 or, at least, when you get the data that are in the CSV, you have to convert them from UTF-8 to latin1.

You can do the convertion following this articles:

• Convert latin1 to UTF8
• http://wordpress.org/support/topic/convert-latin1-to-utf-8

This version does not rely on hard-coded, fixed values but sizes relative to the font-size of the div.

I am trying to obtain a handle on one of the views in the Action Bar

I will assume that you mean something established via android:actionLayout in your <item> element of your <menu> resource.

I have tried calling findViewById(R.id.menu_item)

To retrieve the View associated with your android:actionLayout, call findItem() on the Menu to retrieve the MenuItem, then call getActionView() on the MenuItem. This can be done any time after you have inflated the menu resource.

It was giving Illegal Exception.

My workaround with code:

public void dofirst(){
    System.setProperty("webdriver.chrome.driver","D:\\Softwares\\selenium\\chromedriver_win32\\chromedriver.exe");
    WebDriver driver = new ChromeDriver();
    driver.get("http://www.facebook.com");
}

var d = new Date();

// calling the function
formatDate(d,4);


function formatDate(dateObj,format)
{
    var monthNames = [ "January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December" ];
    var curr_date = dateObj.getDate();
    var curr_month = dateObj.getMonth();
    curr_month = curr_month + 1;
    var curr_year = dateObj.getFullYear();
    var curr_min = dateObj.getMinutes();
    var curr_hr= dateObj.getHours();
    var curr_sc= dateObj.getSeconds();
    if(curr_month.toString().length == 1)
    curr_month = '0' + curr_month;      
    if(curr_date.toString().length == 1)
    curr_date = '0' + curr_date;
    if(curr_hr.toString().length == 1)
    curr_hr = '0' + curr_hr;
    if(curr_min.toString().length == 1)
    curr_min = '0' + curr_min;

    if(format ==1)//dd-mm-yyyy
    {
        return curr_date + "-"+curr_month+ "-"+curr_year;       
    }
    else if(format ==2)//yyyy-mm-dd

}

I wasted a lot of time on this. Turns out that the default database library is not supported for Python 3. You have to use a different one.

I think the current answers are neglecting to highlight the actual important and significant differences and what that means for the intended usage. While they might both work in certain situations because the implementer built in support for both, they have different usage scenarios. Both can annotate properties and methods but here are some important differences:

DisplayAttribute

• defined in the System.ComponentModel.DataAnnotations namespace in the System.ComponentModel.DataAnnotations.dll assembly
• can be used on parameters and fields
• lets you set additional properties like Description or ShortName
• can be localized with resources

DisplayNameAttribute

• DisplayName is in the System.ComponentModel namespace in System.dll
• can be used on classes and events
• cannot be localized with resources

The assembly and namespace speaks to the intended usage and localization support is the big kicker. DisplayNameAttribute has been around since .NET 2 and seems to have been intended more for naming of developer components and properties in the legacy property grid, not so much for things visible to end users that may need localization and such.

DisplayAttribute was introduced later in .NET 4 and seems to be designed specifically for labeling members of data classes that will be end-user visible, so it is more suitable for DTOs, entities, and other things of that sort. I find it rather unfortunate that they limited it so it can't be used on classes though.

EDIT: Looks like latest .NET Core source allows DisplayAttribute to be used on classes now as well.

In your header file say foo.h

class Foo{
    public:
        static void someFunction(params..);
    // other stuff
}

In your implementation file say foo.cpp

#include "foo.h"

void Foo::someFunction(params..){
    // Implementation of someFunction
}

Very Important

Just make sure you don't use the static keyword in your method signature when you are implementing the static function in your implementation file.

Good Luck

var myTimer = setTimeout(..., 115000);
something.click(function () {
    clearTimeout(myTimer);
    myTimer = setTimeout(..., 115000);
}); 

Something along those lines!

To lose the focus when other view is touched , both views should be set as view.focusableInTouchMode(true).

But it seems that use focuses in touch mode are not recommended. Please take a look here: http://android-developers.blogspot.com/2008/12/touch-mode.html

You don't have to do anything special, it should just be working.

When I have a fresh rails app with this controller:

class FooController < ApplicationController
  def index
    raise "error"
  end
end

and go to http://127.0.0.1:3000/foo/

I am seeing the exception with a stack trace.

You might not see the whole stacktrace in the console log because Rails (since 2.3) filters lines from the stack trace that come from the framework itself.

See config/initializers/backtrace_silencers.rb in your Rails project

as docs say:

Note: object does not have a __dict__, so you can’t assign arbitrary attributes to an instance of the object class.

You could just use dummy-class instance.

All other answers didn't quite address what I was looking for which was to convert CString on the fly as opposed to store the result in a variable.

The solution is similar to above but we need one more step to instantiate a nameless object. I am illustrating with an example. Here is my function which needs std::string but I have CString.

void CStringsPlayDlg::writeLog(const std::string &text)
{
    std::string filename = "c:\\test\\test.txt";

    std::ofstream log_file(filename.c_str(), std::ios_base::out | std::ios_base::app);

    log_file << text << std::endl;
}

How to call it when you have a CString?

std::string firstName = "First";
CString lastName = _T("Last");

writeLog( firstName + ", " + std::string( CT2A( lastName ) ) );     

Note that the last line is not a direct typecast but we are creating a nameless std::string object and supply the CString via its constructor.

I implemented it in the following way. I wanted a generic MakeRequest method that could call my API and receive content for the body of the request - and also deserialise the response into the desired type. I create a Dictionary<string, string> object to house the content to be submitted, and then set the HttpRequestMessage Content property with it:

Generic method to call the API:

    private static T MakeRequest<T>(string httpMethod, string route, Dictionary<string, string> postParams = null)
    {
        using (var client = new HttpClient())
        {
            HttpRequestMessage requestMessage = new HttpRequestMessage(new HttpMethod(httpMethod), $"{_apiBaseUri}/{route}");

            if (postParams != null)
                requestMessage.Content = new FormUrlEncodedContent(postParams);   // This is where your content gets added to the request body


            HttpResponseMessage response = client.SendAsync(requestMessage).Result;

            string apiResponse = response.Content.ReadAsStringAsync().Result;
            try
            {
                // Attempt to deserialise the reponse to the desired type, otherwise throw an expetion with the response from the api.
                if (apiResponse != "")
                    return JsonConvert.DeserializeObject<T>(apiResponse);
                else
                    throw new Exception();
            }
            catch (Exception ex)
            {
                throw new Exception($"An error ocurred while calling the API. It responded with the following message: {response.StatusCode} {response.ReasonPhrase}");
            }
        }
    }

Call the method:

    public static CardInformation ValidateCard(string cardNumber, string country = "CAN")
    { 
        // Here you create your parameters to be added to the request content
        var postParams = new Dictionary<string, string> { { "cardNumber", cardNumber }, { "country", country } };
        // make a POST request to the "cards" endpoint and pass in the parameters
        return MakeRequest<CardInformation>("POST", "cards", postParams);
    }

You could put the body of your script into a function and then you could return from that function.

def main():
  done = True
  if done:
    return
    # quit/stop/exit
  else:
    # do other stuff

if __name__ == "__main__":
  #Run as main program
  main()

thy this:

@UiThread
    public void logMsg(final String msg) {
        new Handler(Looper.getMainLooper()).post(new Runnable() {
            @Override
            public void run() {
                Log.d("UI thread", "I am the UI thread");


            }
        });
    }

This is a few months late but I thought I'd provide my solution based on this here tutorial. The gist of it is that it's a lot easier to manage once you change the way you approach forms.

First, use ReactiveFormsModule instead of or in addition to the normal FormsModule. With reactive forms you create your forms in your components/services and then plug them into your page instead of your page generating the form itself. It's a bit more code but it's a lot more testable, a lot more flexible, and as far as I can tell the best way to make a lot of non-trivial forms.

The end result will look a little like this, conceptually:

• You have one base FormGroup with whatever FormControl instances you need for the entirety of the form. For example, as in the tutorial I linked to, lets say you want a form where a user can input their name once and then any number of addresses. All of the one-time field inputs would be in this base form group.

• Inside that FormGroup instance there will be one or more FormArray instances. A FormArray is basically a way to group multiple controls together and iterate over them. You can also put multiple FormGroup instances in your array and use those as essentially "mini-forms" nested within your larger form.

• By nesting multiple FormGroup and/or FormControl instances within a dynamic FormArray, you can control validity and manage the form as one, big, reactive piece made up of several dynamic parts. For example, if you want to check if every single input is valid before allowing the user to submit, the validity of one sub-form will "bubble up" to the top-level form and the entire form becomes invalid, making it easy to manage dynamic inputs.

• As a FormArray is, essentially, a wrapper around an array interface but for form pieces, you can push, pop, insert, and remove controls at any time without recreating the form or doing complex interactions.

In case the tutorial I linked to goes down, here some sample code you can implement yourself (my examples use TypeScript) that illustrate the basic ideas:

Base Component code:

import { Component, Input, OnInit } from '@angular/core';
import { FormArray, FormBuilder, FormGroup, Validators } from '@angular/forms';

@Component({
  selector: 'my-form-component',
  templateUrl: './my-form.component.html'
})
export class MyFormComponent implements OnInit {
    @Input() inputArray: ArrayType[];
    myForm: FormGroup;

    constructor(private fb: FormBuilder) {}
    ngOnInit(): void {
        let newForm = this.fb.group({
            appearsOnce: ['InitialValue', [Validators.required, Validators.maxLength(25)]],
            formArray: this.fb.array([])
        });

        const arrayControl = <FormArray>newForm.controls['formArray'];
        this.inputArray.forEach(item => {
            let newGroup = this.fb.group({
                itemPropertyOne: ['InitialValue', [Validators.required]],
                itemPropertyTwo: ['InitialValue', [Validators.minLength(5), Validators.maxLength(20)]]
            });
            arrayControl.push(newGroup);
        });

        this.myForm = newForm;
    }
    addInput(): void {
        const arrayControl = <FormArray>this.myForm.controls['formArray'];
        let newGroup = this.fb.group({

            /* Fill this in identically to the one in ngOnInit */

        });
        arrayControl.push(newGroup);
    }
    delInput(index: number): void {
        const arrayControl = <FormArray>this.myForm.controls['formArray'];
        arrayControl.removeAt(index);
    }
    onSubmit(): void {
        console.log(this.myForm.value);
        // Your form value is outputted as a JavaScript object.
        // Parse it as JSON or take the values necessary to use as you like
    }
}

Sub-Component Code: (one for each new input field, to keep things clean)

import { Component, Input } from '@angular/core';
import { FormGroup } from '@angular/forms';

@Component({
    selector: 'my-form-sub-component',
    templateUrl: './my-form-sub-component.html'
})
export class MyFormSubComponent {
    @Input() myForm: FormGroup; // This component is passed a FormGroup from the base component template
}

Base Component HTML

<form [formGroup]="myForm" (ngSubmit)="onSubmit()" novalidate>
    <label>Appears Once:</label>
    <input type="text" formControlName="appearsOnce" />

    <div formArrayName="formArray">
        <div *ngFor="let control of myForm.controls['formArray'].controls; let i = index">
            <button type="button" (click)="delInput(i)">Delete</button>
            <my-form-sub-component [myForm]="myForm.controls.formArray.controls[i]"></my-form-sub-component>
        </div>
    </div>
    <button type="button" (click)="addInput()">Add</button>
    <button type="submit" [disabled]="!myForm.valid">Save</button>
</form>

Sub-Component HTML

<div [formGroup]="form">
    <label>Property One: </label>
    <input type="text" formControlName="propertyOne"/>

    <label >Property Two: </label>
    <input type="number" formControlName="propertyTwo"/>
</div>

In the above code I basically have a component that represents the base of the form and then each sub-component manages its own FormGroup instance within the FormArray situated inside the base FormGroup. The base template passes along the sub-group to the sub-component and then you can handle validation for the entire form dynamically.

Also, this makes it trivial to re-order component by strategically inserting and removing them from the form. It works with (seemingly) any number of inputs as they don't conflict with names (a big downside of template-driven forms as far as I'm aware) and you still retain pretty much automatic validation. The only "downside" of this approach is, besides writing a little more code, you do have to relearn how forms work. However, this will open up possibilities for much larger and more dynamic forms as you go on.

If you have any questions or want to point out some errors, go ahead. I just typed up the above code based on something I did myself this past week with the names changed and other misc. properties left out, but it should be straightforward. The only major difference between the above code and my own is that I moved all of the form-building to a separate service that's called from the component so it's a bit less messy.

Image can not be shown until it serves from any server. so you need to upload the image to your server to show its preview.

Here is another variant using a generator function that works for integers:

def ncomma(num):
    def _helper(num):
        # assert isinstance(numstr, basestring)
        numstr = '%d' % num
        for ii, digit in enumerate(reversed(numstr)):
            if ii and ii % 3 == 0 and digit.isdigit():
                yield ','
            yield digit

    return ''.join(reversed([n for n in _helper(num)]))

And here's a test:

>>> for i in (0, 99, 999, 9999, 999999, 1000000, -1, -111, -1111, -111111, -1000000):
...     print i, ncomma(i)
... 
0 0
99 99
999 999
9999 9,999
999999 999,999
1000000 1,000,000
-1 -1
-111 -111
-1111 -1,111
-111111 -111,111
-1000000 -1,000,000

How about doing it like this:

1) show popup with form

2) submit form using AJAX

3) in AJAX server side code, render response that will either:

• show popup with form with validations or just a message
• close the popup (and maybe redirect you to new page)

Check out the Programmatically Displaying the Settings Page

    startActivity(context, new Intent(Settings.ACTION_SETTINGS), /*options:*/ null);

In general, you use the predefined constant Settings.ACTION__SETTINGS. The full list can be found here

There are two types of messages: notification messages and data messages. If you only send data message, that is without notification object in your message string. It would be invoked when your app in background.

        Calendar calendar = Calendar.getInstance();
        SimpleDateFormat simpleDateFormat = 
                new SimpleDateFormat("dd:MMMM:yyyy HH:mm:ss a");
        final String strDate = simpleDateFormat.format(calendar.getTime());

        runOnUiThread(new Runnable(){

In (the current) IPython 3.2.0 (Python 2 or 3)

Open the configuration file within the hidden folder .ipython

~/.ipython/profile_default/ipython_kernel_config.py

add the following line

c.IPKernelApp.matplotlib = 'inline'

add it straight after

c = get_config()

This worked for me:

1. Delete the originally created site.
2. Recreate the site in IIS
3. Clean solution
4. Build solution

Seems like something went south when I originally created the site. I hate solutions that are similar to "Restart your machine, then reinstall windows" without knowing what caused the error. But, this worked for me. Quick and simple. Hope it helps someone else.

Without importing anything a straight substitution of one character for a space, the target separator for words is a space. Something like:

words [if c == ',' then ' ' else c|c <- "my,comma,separated,list"]

or

words let f ',' = ' '; f c = c in map f "my,comma,separated,list"

You can make this into a function with parameters. You can eliminate the parameter character-to-match my matching many, like in:

 [if elem c ";,.:-+@!$#?" then ' ' else c|c <-"my,comma;separated!list"]

I believe you can accomplish it by just having single ng-view. In the main template you can have ng-include sections for sub views, then in the main controller define model properties for each sub template. So that they will bind automatically to ng-include sections. This is same as having multiple ng-view

You can check the example given in ng-include documentation

in the example when you change the template from dropdown list it changes the content. Here assume you have one main ng-view and instead of manually selecting sub content by selecting drop down, you do it as when main view is loaded.

I had the same problem. I wrote my own function using replace on innerHTML, but it would screw up anchor links and such.

To make it work correctly I used a library to get this done.

The library has an awesome API. After including the script I called it like this:

findAndReplaceDOMText(document.body, {
  find: 'texttofind',
  replace: 'texttoreplace'
  }
);

I'm not sure I'm repeating someone but some time ago some good soul wrote Y-operator for recursively called function like:

def tail_recursive(func):
  y_operator = (lambda f: (lambda y: y(y))(lambda x: f(lambda *args: lambda: x(x)(*args))))(func)
  def wrap_func_tail(*args):
    out = y_operator(*args)
    while callable(out): out = out()
    return out
  return wrap_func_tail

and then recursive function needs form:

def my_recursive_func(g):
  def wrapped(some_arg, acc):
    if <condition>: return acc
    return g(some_arg, acc)
  return wrapped

# and finally you call it in code

(tail_recursive(my_recursive_func))(some_arg, acc)

for Fibonacci numbers your function looks like this:

def fib(g):
  def wrapped(n_1, n_2, n):
    if n == 0: return n_1
    return g(n_2, n_1 + n_2, n-1)
  return wrapped

print((tail_recursive(fib))(0, 1, 1000000))

output:

..684684301719893411568996526838242546875

(actually tones of digits)

the strtok runtime function works like this

the first time you call strtok you provide a string that you want to tokenize

char s[] = "this is a string";

in the above string space seems to be a good delimiter between words so lets use that:

char* p = strtok(s, " ");

what happens now is that 's' is searched until the space character is found, the first token is returned ('this') and p points to that token (string)

in order to get next token and to continue with the same string NULL is passed as first argument since strtok maintains a static pointer to your previous passed string:

p = strtok(NULL," ");

p now points to 'is'

and so on until no more spaces can be found, then the last string is returned as the last token 'string'.

more conveniently you could write it like this instead to print out all tokens:

for (char *p = strtok(s," "); p != NULL; p = strtok(NULL, " "))
{
  puts(p);
}

EDIT:

If you want to store the returned values from strtok you need to copy the token to another buffer e.g. strdup(p); since the original string (pointed to by the static pointer inside strtok) is modified between iterations in order to return the token.

In my case, the annotation was on the getter() method instead of the field itself (ported from a legacy application).

Spring ignores the annotation in this case as well but doesn't complain. The solution was to move it to the field instead of the getter.

The others are right about making the driver JAR available to your servlet container. My comment was meant to suggest that you verify from the command line whether the driver itself is intact.

Rather than an empty main(), try something like this, adapted from the included documentation:

public class LoadDriver {
    public static void main(String[] args) throws Exception {
        Class.forName("com.mysql.jdbc.Driver");
    }
}

On my platform, I'd do this:

$ ls mysql-connector-java-5.1.12-bin.jar 
mysql-connector-java-5.1.12-bin.jar
$ javac LoadDriver.java 
$ java -cp mysql-connector-java-5.1.12-bin.jar:. LoadDriver

On your platform, you need to use ; as the path separator, as discussed here and here.

If you are running IIS 8 with windows server 2012 you need to do the following:

1. Click Server Manager
2. Add roles and features
3. Click next and then Role-based
4. Select your server
5. In the tree choose Web Server(IIS) >> Web Server >> Application Development >> ASP
6. Next and finish

from then on your application should start running

The Node Knockout competition wrapped up recently, and many of the submissions are available on github. The competition site doesn't appear to be working right now, but I'm sure you could Google up a few entries to check out.

1. According to composer's manual:

   require-dev (root-only)

   Lists packages required for developing this package, or running tests, etc. The dev requirements of the root package are installed by default. Both install or update support the --no-dev option that prevents dev dependencies from being installed.

   So running composer install will also download the development dependencies.

2. The reason is actually quite simple. When contributing to a specific library you may want to run test suites or other develop tools (e.g. symfony). But if you install this library to a project, those development dependencies may not be required: not every project requires a test runner.

This error happens very rarely on my Windows machine. I ended up rebooting the machine, and the error went away.

with x as   (select  *,rn = row_number()
            over(PARTITION BY OrderNo,item  order by OrderNo)
            from    #temp1)

select * from x
where rn > 1

you can remove duplicates by replacing select statement by

delete x where rn > 1

I had come across this issue for a complex model with several nested objects. A good example of what I was looking at doing would be this: Lets say you have a polaroid of yourself. And that picture is then put into a trunk of a car. The car is inside of a large crate. The crate is in the hold of a large ship with many other crates. I had to search the hold, look in the crates, check the trunk, and then look for an existing picture of me.

I could not find any good solutions online to use, and using .filter() only works on arrays. Most solutions suggested just checking to see if model["yourpicture"] existed. This was very undesirable because, from the example, that would only search the hold of the ship and I needed a way to get them from farther down the rabbit hole.

This is the recursive solution I made. In comments, I confirmed from T.J. Crowder that a recursive version would be required. I thought I would share it in case anyone came across a similar complex situation.

function ContainsKeyValue( obj, key, value ){
    if( obj[key] === value ) return true;
    for( all in obj )
    {
        if( obj[all] != null && obj[all][key] === value ){
            return true;
        }
        if( typeof obj[all] == "object" && obj[all]!= null ){
            var found = ContainsKeyValue( obj[all], key, value );
            if( found == true ) return true;
        }
    }
    return false;
}

This will start from a given object inside of the graph, and recurse down any objects found. I use it like this:

var liveData = [];
for( var items in viewmodel.Crates )
{
    if( ContainsKeyValue( viewmodel.Crates[items], "PictureId", 6 ) === true )
    {
        liveData.push( viewmodel.Crates[items] );
    }
}

Which will produce an array of the Crates which contained my picture.

Below mentioned code works perfectly fine for taking length of any characters entered in textbox.

$("#Texboxid").val().length;

Whilst agreeing with Douwe Maan and Erik's answers, there are a couple of other things here that you may find useful.

Firstly, within your head tags, you can reference a separate JavaScript file, which is then reusable:

<script language="JavaScript" src="/common/common.js"></script>

where common.js is your reusable function file in a top-level directory called common.

Secondly, you can delay the operation of a script using setTimeout, e.g.:

setTimeout(someFunction, 5000);

The second argument is in milliseconds. I mention this, because you appear to be trying to delay something in your original code snippet.

This past week I installed Microsoft SQL Server 2014 Developer Edition on my dev box, and immediately ran into a problem I had never seen before.

I’ve installed various versions of SQL Server countless times, and it is usually a painless procedure. Install the server, run the Management Console, it’s that simple. However, after completing this installation, when I tried to log in to the server using SSMS, I got an error like the one below:

SQL Server login error 18456 “Login failed for user… (Microsoft SQL Server, Error: 18456)” I’m used to seeing this error if I typed the wrong password when logging in – but that’s only if I’m using mixed mode (Windows and SQL Authentication). In this case, the server was set up with Windows Authentication only, and the user account was my own. I’m still not sure why it didn’t add my user to the SYSADMIN role during setup; perhaps I missed a step and forgot to add it. At any rate, not all hope was lost.

The way to fix this, if you cannot log on with any other account to SQL Server, is to add your network login through a command line interface. For this to work, you need to be an Administrator on Windows for the PC that you’re logged onto.

Stop the MSSQL service. Open a Command Prompt using Run As Administrator. Change to the folder that holds the SQL Server EXE file; the default for SQL Server 2014 is “C:\Program Files\Microsoft SQL Server\MSSQL12.MSSQLSERVER\MSSQL\Binn”. Run the following command: “sqlservr.exe –m”. This will start SQL Server in single-user mode. While leaving this Command Prompt open, open another one, repeating steps 2 and 3. In the second Command Prompt window, run “SQLCMD –S Server_Name\Instance_Name” In this window, run the following lines, pressing Enter after each one: 1

CREATE LOGIN [domainName\loginName] FROM WINDOWS 2 GO 3 SP_ADDSRVROLEMEMBER 'LOGIN_NAME','SYSADMIN' 4 GO Use CTRL+C to end both processes in the Command Prompt windows; you will be prompted to press Y to end the SQL Server process.

Restart the MSSQL service. That’s it! You should now be able to log in using your network login.

  AND P.shopkeeper = '89137';

In case you were struggling to change linetypes, the following answer should be helpful. (This is an addition to the solution by Andy W.)

We will try to extend the learned pattern:

cols <- c("LINE1"="#f04546","LINE2"="#3591d1","BAR"="#62c76b")
line_types <- c("LINE1"=1,"LINE2"=3)
ggplot(data=data,aes(x=a)) + 
  geom_bar(stat="identity", aes(y=h,fill = "BAR"))+ #green
  geom_line(aes(y=b,group=1, colour="LINE1", linetype="LINE1"),size=0.5) +   #red
  geom_point(aes(y=b, colour="LINE1", fill="LINE1"),size=2) +           #red
  geom_line(aes(y=c,group=1,colour="LINE2", linetype="LINE2"),size=0.5) +   #blue 
  geom_point(aes(y=c,colour="LINE2", fill="LINE2"),size=2) +           #blue
  scale_colour_manual(name="Error Bars",values=cols, 
                  guide = guide_legend(override.aes=aes(fill=NA))) + 
  scale_linetype_manual(values=line_types)+
  scale_fill_manual(name="Bar",values=cols, guide="none") +
  ylab("Symptom severity") + xlab("PHQ-9 symptoms") +
  ylim(0,1.6) +
  theme_bw() +
  theme(axis.title.x = element_text(size = 15, vjust=-.2)) +
  theme(axis.title.y = element_text(size = 15, vjust=0.3))

However, what we get is the following result:

The problem is that the linetype is not merged in the main legend. Note that we did not give any name to the method scale_linetype_manual. The trick which works here is to give it the same name as what you used for naming scale_colour_manual. More specifically, if we change the corresponding line to the following we get the desired result:

scale_linetype_manual(name="Error Bars",values=line_types)

Now, it is easy to change the size of the line with the same idea.

Note that the geom_bar has not colour property anymore. (I did not try to fix this issue.) Also, adding geom_errorbar with colour attribute spoils the result. It would be great if somebody can come up with a better solution which resolves these two issues as well.

This works too:

System.DateTime dTime = DateTime.Now();

// tSpan is 0 days, 1 hours, 30 minutes and 0 second.
System.TimeSpan tSpan = new System.TimeSpan(0, 1, 3, 0); 

System.DateTime result = dTime + tSpan;

To subtract a year:

DateTime DateEnd = DateTime.Now;
DateTime DateStart = DateEnd - new TimeSpan(365, 0, 0, 0);

Use the DATEDIFF() function.

Example from documentation:

SELECT DATEDIFF('2007-12-31 23:59:59','2007-12-30');
    -> 1

Following this guide I had the same issue. To expand on Eric Moore's ridiculously vague answer,

Right click > TortoiseGit > Settings > Network

Down the bottom in the "SSH" section, hit Browse and find your TortoiseGit\bin\TortoisePlink.exe file. In my case the path was under Programs as opposed to Program Files

git revert -m allows to un-merge still keeping the history of both merge and un-do operation. Might be good for documenting probably.

Here's a document from Microsoft themselves. Hope that helps..., it's from 2003, but it might still be relevant.

You can try the performClick method :

View view = bottomNavigationView.findViewById(R.id.YOUR_ACTION);
view.performClick();

Edit

From API 25.3.0 it was introduced the method setSelectedItemId(int id) which lets you mark an item as selected as if it was tapped.

If you do not want to define a separate class for nested json , Defining nested json object as JsonNode should work ,for example :

{"id":2,"socket":"0c317829-69bf-43d6-b598-7c0c550635bb","type":"getDashboard","data":{"workstationUuid":"ddec1caa-a97f-4922-833f-632da07ffc11"},"reply":true}

@JsonProperty("data")
    private JsonNode data;

In C you could use the combination of the setjmp() and longjmp() functions, defined in setjmp.h. Example from Wikipedia

#include <stdio.h>
#include <setjmp.h>

static jmp_buf buf;

void second(void) {
    printf("second\n");         // prints
    longjmp(buf,1);             // jumps back to where setjmp 
                                //   was called - making setjmp now return 1
}

void first(void) {
    second();
    printf("first\n");          // does not print
}

int main() {   
    if ( ! setjmp(buf) ) {
        first();                // when executed, setjmp returns 0
    } else {                    // when longjmp jumps back, setjmp returns 1
        printf("main");         // prints
    }

    return 0;
}

Note: I would actually advise you not to use them as they work awful with C++ (destructors of local objects wouldn't get called) and it is really hard to understand what is going on. Return some kind of error instead.

Here's my take if you want to try using multiprocesses to process each row of numpy array,

from multiprocessing import Pool
import numpy as np

def my_function(x):
    pass     # do something and return something

if __name__ == '__main__':    
    X = np.arange(6).reshape((3,2))
    pool = Pool(processes = 4)
    results = pool.map(my_function, map(lambda x: x, X))
    pool.close()
    pool.join()

pool.map take in a function and an iterable.
I used 'map' function to create an iterator over each rows of the array.
Maybe there's a better to create the iterable though.

If you intend to change A, B, C.... you see high above the columns, you can not. You can hide A, B, C...: Button Office(top left) Excel Options(bottom) Advanced(left) Right looking: Display options fot this worksheet: Select the worksheet(eg. Sheet3) Uncheck: Show column and row headers Ok

I think you change

compile 'com.google.firebase:firebase-messaging:11.0.4'

As others have suggested, you are not clearly explaining your problem, what you are trying to do, or what your expectations are as to what this function is actually supposed to do.

If I have understood correctly, then you are expecting this function to refresh the page for you (you actually use the term "reloads the browser").

But this function is not intended to reload the browser.

All the function does, is to add (push) a new "state" onto the browser history, so that in future, the user will be able to return to this state that the web-page is now in.

Normally, this is used in conjunction with AJAX calls (which refresh only a part of the page).

For example, if a user does a search "CATS" in one of your search boxes, and the results of the search (presumably cute pictures of cats) are loaded back via AJAX, into the lower-right of your page -- then your page state will not be changed. In other words, in the near future, when the user decides that he wants to go back to his search for "CATS", he won't be able to, because the state doesn't exist in his history. He will only be able to click back to your blank search box.

Hence the need for the function

history.pushState({},"Results for `Cats`",'url.html?s=cats');

It is intended as a way to allow the programmer to specifically define his search into the user's history trail. That's all it is intended to do.

When the function is working properly, the only thing you should expect to see, is the address in your browser's address-bar change to whatever you specify in your URL.

If you already understand this, then sorry for this long preamble. But it sounds from the way you pose the question, that you have not.

As an aside, I have also found some contradictions between the way that the function is described in the documentation, and the way it works in reality. I find that it is not a good idea to use blank or empty values as parameters.

See my answer to this SO question. So I would recommend putting a description in your second parameter. From memory, this is the description that the user sees in the drop-down, when he clicks-and-holds his mouse over "back" button.

With curl and jq:

curl -s <jenkins_url>/pluginManager/api/json?depth=1 \
  | jq -r '.plugins[] | "\(.shortName):\(.version)"' \

ant:1.8
apache-httpcomponents-client-4-api:4.5.5-3.0

I have wrote extension method:

public static string ReplaceIgnoreCase(this string source, string oldVale, string newVale)
    {
        if (source.IsNullOrEmpty() || oldVale.IsNullOrEmpty())
            return source;

        var stringBuilder = new StringBuilder();
        string result = source;

        int index = result.IndexOf(oldVale, StringComparison.InvariantCultureIgnoreCase);

        while (index >= 0)
        {
            if (index > 0)
                stringBuilder.Append(result.Substring(0, index));

            if (newVale.IsNullOrEmpty().IsNot())
                stringBuilder.Append(newVale);

            stringBuilder.Append(result.Substring(index + oldVale.Length));

            result = stringBuilder.ToString();

            index = result.IndexOf(oldVale, StringComparison.InvariantCultureIgnoreCase);
        }

        return result;
    }

I use two additional extension methods for previous extension method:

    public static bool IsNullOrEmpty(this string value)
    {
        return string.IsNullOrEmpty(value);
    }

    public static bool IsNot(this bool val)
    {

Whenever you're confused, I would suggest consulting the Javadoc as the first place for your clarification.

From the javadoc about System, here's what the doc says:

public final class System
extends Object

The System class contains several useful class fields and methods. It cannot be instantiated.
Among the facilities provided by the System class are standard input, standard output, and error output streams; access to externally defined properties and environment variables; a means of loading files and libraries; and a utility method for quickly copying a portion of an array.

Since:
JDK1.0

Regarding System.out

public static final PrintStream out
The "standard" output stream. This stream is already open and ready to accept output data. Typically this stream corresponds to display output or another output destination specified by the host environment or user.
For simple stand-alone Java applications, a typical way to write a line of output data is:

     System.out.println(data)

First of all you do not need a .py.

If you have a file a.py and inside you have some functions:

def b():
  # Something
  return 1

def c():
  # Something
  return 2

And you want to import them in z.py you have to write

from a import b, c

MVC is just a general design pattern that, in the context of lean web app development, makes it easy for the developer to keep the HTML markup in an app’s presentation layer (the view) separate from the methods that receive and handle client requests (the controllers) and the data representations that are returned within the view (the models). It’s all about separation of concerns, that is, keeping code that serves one functional purpose (e.g. handling client requests) sequestered from code that serves an entirely different functional purpose (e.g. representing data).

It’s the same principle for why anybody who’s spent more than 5 min trying to build a website can appreciate the need to keep your HTML markup, JavaScript, and CSS in separate files: If you just dump all of your code into a single file, you end up with spaghetti that’s virtually un-editable later on.

Since you asked for possible "cons": I’m no authority on software architecture design, but based on my experience developing in MVC, I think it’s also important to point out that following a strict, no-frills MVC design pattern is most useful for 1) lightweight web apps, or 2) as the UI layer of a larger enterprise app. I’m surprised this specification isn’t talked about more, because MVC contains no explicit definitions for your business logic, domain models, or really anything in the data access layer of your app. When I started developing in ASP.NET MVC (i.e. before I knew other software architectures even existed), I would end up with very bloated controllers or even view models chock full of business logic that, had I been working on enterprise applications, would have made it difficult for other devs who were unfamiliar with my code to modify (i.e. more spaghetti).

It is kind of screwy, but in a pinch you can use sed or awk to make small edits or remove text. Be careful with your regex targets of course and be aware that you're likely root on your container and might have to re-adjust permissions.

For example, removing a full line that contains text matching a regex:

awk '!/targetText/' file.txt > temp && mv temp file.txt

(More)

First of all you should use double "==" instead of "=" to compare two values. Using "=" You assigning value to variable in this case "somevar"

        DataContext = new ViewModelBase();
    }
}

The ViewModel:

public class ViewModelBase
{
    private ICommand _clickCommand;
    public ICommand ClickCommand
    {
        get
        {
            return _clickCommand ?? (_clickCommand = new CommandHandler(() => MyAction(), ()=> CanExecute));
        }
    }
     public bool CanExecute
     {
        get
        {
            // check if executing is allowed, i.e., validate, check if a process is running, etc. 
            return true/false;
        }
     }

    public void MyAction()
    {

    }
}

Command Handler:

 public class CommandHandler : ICommand
{
    private Action _action;
    private Func<bool> _canExecute;

    /// <summary>
    /// Creates instance of the command handler
    /// </summary>
    /// <param name="action">Action to be executed by the command</param>
    /// <param name="canExecute">A bolean property to containing current permissions to execute the command</param>
    public CommandHandler(Action action, Func<bool> canExecute)
    {
        _action = action;
        _canExecute = canExecute;
    }

    /// <summary>
    /// Wires CanExecuteChanged event 
    /// </summary>
    public event EventHandler CanExecuteChanged
    {
        add { CommandManager.RequerySuggested += value; }
        remove { CommandManager.RequerySuggested -= value; }
    }

    /// <summary>
    /// Forcess checking if execute is allowed
    /// </summary>
    /// <param name="parameter"></param>
    /// <returns></returns>
    public bool CanExecute(object parameter)
    {
        return _canExecute.Invoke();
    }

    public void Execute(object parameter)
    {
        _action();
    }
}

I hope this will give you the idea.

const idivmod = (a, b) => [a/b |0, a%b];

there is also a proposal working on it Modulus and Additional Integer Math

You can try the Anthem library.

So I had a lot of problems with all of the solutions mentioned so far...

I have a local package that I want to always reference (rather than npm link) because it won't be used outside of this project (for now) and also won't be uploaded to an npm repository for wide use as of yet.

I also need it to work on Windows AND Unix, so sym-links aren't ideal.

Pointing to the tar.gz result of (npm package) works for the dependent npm package folder, however this causes issues with the npm cache if you want to update the package. It doesn't always pull in the new one from the referenced npm package when you update it, even if you blow away node_modules and re-do your npm-install for your main project.

so.. This is what worked well for me!

Main Project's Package.json File Snippet:

  "name": "main-project-name",
  "version": "0.0.0",
  "scripts": {
    "ng": "ng",
    ...
    "preinstall": "cd ../some-npm-package-angular && npm install && npm run build"
  },
  "private": true,
  "dependencies": {
    ...
    "@com/some-npm-package-angular": "file:../some-npm-package-angular/dist",
    ...
  }

This achieves 3 things:

• Avoids the common error (at least with angular npm projects) "index.ts is not part of the compilation." - as it points to the built (dist) folder.
• Adds a preinstall step to build the referenced npm client package to make sure the dist folder of our dependent package is built.
• Avoids issues where referencing a tar.gz file locally may be cached by npm and not updated in the main project without lots of cleaning/troubleshooting/re-building/re-installing.

I hope this is clear, and helps someone out.

The tar.gz approach also sort of works..

npm install (file path) also sort of works.

This was all based off of a generated client from an openapi spec that we wanted to keep in a separate location (rather than using copy-pasta for individual files)

====== UPDATE: ======

There are additional errors with a regular development flow with the above solution, as npm's versioning scheme with local files is absolutely terrible. If your dependent package changes frequently, this whole scheme breaks because npm will cache your last version of the project and then blow up when the SHA hash doesn't match anymore with what was saved in your package-lock.json file, among other issues.

As a result, I recommend using the *.tgz approach with a version update for each change. This works by doing three things.

First:

For your dependent package, use the npm library "ng-packagr". This is automatically added to auto-generated client packages created by the angular-typescript code generator for OpenAPI 3.0.

As a result the project that I'm referencing has a "scripts" section within package.json that looks like this:

  "scripts": {
    "build": "ng-packagr -p ng-package.json",
    "package": "npm install && npm run build && cd dist && npm pack"
  },

And the project referencing this other project adds a pre-install step to make sure the dependent project is up to date and rebuilt before building itself:

  "scripts": {
    "preinstall": "npm run clean && cd ../some-npm-package-angular && npm run package"
  },

Second

Reference the built tgz npm package from your main project!

  "dependencies": {
    "@com/some-npm-package-angular": "file:../some-npm-package-angular/dist/some-npm-package-angular-<packageVersion>.tgz",
    ...
  }

Third

Update the dependent package's version EVERY TIME you update the dependent package. You'll also have to update the version in the main project.

If you do not do this, NPM will choke and use a cached version and explode when the SHA hash doesn't match. NPM versions file-based packages based on the filename changing. It won't check the package itself for an updated version in package.json, and the NPM team stated that they will not fix this, but people keep raising the issue: https://github.com/microsoft/WSL/issues/348

for now, just update the:

"version": "1.0.0-build5",

In the dependent package's package.json file, then update your reference to it in the main project to reference the new filename, ex:

"dependencies": {
       "@com/some-npm-package-angular": "file:../some-npm-package-angular/dist/some-npm-package-angular-1.0.0-build5.tgz",
        ...
}

You get used to it. Just update the two package.json files - version then the ref to the new filename.

Hope that helps someone...

I know its too longtime to reply but just as an information purpose for future readers:

WebRequest

System.Object
    System.MarshalByRefObject
        System.Net.WebRequest

The WebRequest is an abstract base class. So you actually don't use it directly. You use it through it derived classes - HttpWebRequest and FileWebRequest.

You use Create method of WebRequest to create an instance of WebRequest. GetResponseStream returns data stream.

There are also FileWebRequest and FtpWebRequest classes that inherit from WebRequest. Normally, you would use WebRequest to, well, make a request and convert the return to either HttpWebRequest, FileWebRequest or FtpWebRequest, depend on your request. Below is an example:

Example:

var _request = (HttpWebRequest)WebRequest.Create("http://stackverflow.com");
var _response = (HttpWebResponse)_request.GetResponse();

WebClient

System.Object
        System.MarshalByRefObject
            System.ComponentModel.Component
                System.Net.WebClient

WebClient provides common operations to sending and receiving data from a resource identified by a URI. Simply, it’s a higher-level abstraction of HttpWebRequest. This ‘common operations’ is what differentiate WebClient from HttpWebRequest, as also shown in the sample below:

Example:

var _client = new WebClient();
var _stackContent = _client.DownloadString("http://stackverflow.com");

There are also DownloadData and DownloadFile operations under WebClient instance. These common operations also simplify code of what we would normally do with HttpWebRequest. Using HttpWebRequest, we have to get the response of our request, instantiate StreamReader to read the response and finally, convert the result to whatever type we expect. With WebClient, we just simply call DownloadData, DownloadFile or DownloadString.

However, keep in mind that WebClient.DownloadString doesn’t consider the encoding of the resource you requesting. So, you would probably end up receiving weird characters if you don’t specify and encoding.

NOTE: Basically "WebClient takes few lines of code as compared to Webrequest"

For integers, there is no difference between pre- and post-increment.

If i is an object of a non-trivial class, then ++i is generally preferred, because the object is modified and then evaluated, whereas i++ modifies after evaluation, so requires a copy to be made.

Using the cordova-device-plugin, you can detect

Can't you originally get the data as a JSONObject?

Perhaps parse the string as both a JSONObject and a JSONArray in the first place? Where is the JSON string coming from?

I'm not sure that it is possible to convert a JsonArray into a JsonObject.

I presume you are using the following from json.org

• JSONObject.java
  A JSONObject is an unordered collection of name/value pairs. Its external form is a string wrapped in curly braces with colons between the names and values, and commas between the values and names. The internal form is an object having get() and opt() methods for accessing the values by name, and put() methods for adding or replacing values by name. The values can be any of these types: Boolean, JSONArray, JSONObject, Number, and String, or the JSONObject.NULL object.

• JSONArray.java
  A JSONArray is an ordered sequence of values. Its external form is a string wrapped in square brackets with commas between the values. The internal form is an object having get() and opt() methods for accessing the values by index, and put() methods for adding or replacing values. The values can be any of these types: Boolean, JSONArray, JSONObject, Number, and String, or the JSONObject.NULL object.

Some RFID chips are read-write, the majority are read-only. You can find out if your chip is read-only by checking the datasheet.

It looks like Google actively frowns on using IP-to-location mapping:

https://developers.google.com/maps/articles/geolocation?hl=en

That article encourages using the W3C geolocation API. I was a little skeptical, but it looks like almost every major browser already supports the geolocation API:

Ideally you shouldn't be splitting strings in T-SQL at all.

Barring that change, on older versions before SQL Server 2016, create a split function:

CREATE FUNCTION dbo.SplitStrings
(
    @List      nvarchar(max), 
    @Delimiter nvarchar(2)
)
RETURNS TABLE
WITH SCHEMABINDING
AS
  RETURN ( WITH x(x) AS
    (
      SELECT CONVERT(xml, N'<root><i>' 
        + REPLACE(@List, @Delimiter, N'</i><i>') 
        + N'</i></root>')
    )
    SELECT Item = LTRIM(RTRIM(i.i.value(N'.',N'nvarchar(max)')))
      FROM x CROSS APPLY x.nodes(N'//root/i') AS i(i)
  );
GO

Now you can say:

DECLARE @Values varchar(1000);

SET @Values = 'A, B, C';

SELECT blah
  FROM dbo.foo
  INNER JOIN dbo.SplitStrings(@Values, ',') AS s
    ON s.Item = foo.myField;

On SQL Server 2016 or above (or Azure SQL Database), it is much simpler and more efficient, however you do have to manually apply LTRIM() to take away any leading spaces:

DECLARE @Values varchar(1000) = 'A, B, C';

SELECT blah
  FROM dbo.foo
  INNER JOIN STRING_SPLIT(@Values, ',') AS s
    ON LTRIM(s.value) = foo.myField;

There is a method specifically for this purpose:

data.splitlines()
['a,b,c', 'd,e,f', 'g,h,i', 'j,k,l']

• All as varchar (they aren't numbers but "collections of digits")
• Country + area + number separately
• Not all countries have area code (eg Malta where I am)
• Some countries drop the leading zero from the area code when dialling internal (eg UK)
• Format in the client code

The problem is that readlines is a list of strings, each of which is a line of filename. Perhaps you meant:

for line in readlines:
    Type = line.split(",")
    x = Type[1]
    y = Type[2]
    print(x,y)

If you were looking for what to use in android, it is:

String android.text.TextUtils.join(CharSequence delimiter, Object[] tokens)

for example:

String joined = TextUtils.join(";", MyStringArray);
