I also had the same issue.Make a directory in dbpath.In my case there wasn't a directory in /data/db .So i created one.Now its working.Make sure to give permission to that directory.

You can always use iptables to delete the rules. If you have a lot of rules, just output them using the following command.

iptables-save > myfile

vi to edit them from the commend line. Just use the "dd" to delete the lines you no longer want.

iptables-restore < myfile and you're good to go.  

REMEMBER THAT IF YOU DON'T CONFIGURE YOUR OS TO SAVE THE RULES TO A FILE AND THEN LOAD THE FILE DURING THE BOOT THAT YOUR RULES WILL BE LOST.

The receiver must set port of receiver to match port set in sender DatagramPacket. For debugging try listening on port > 1024 (e.g. 8000 or 9000). Ports < 1024 are typically used by system services and need admin access to bind on such a port.

If the receiver sends packet to the hard-coded port it's listening to (e.g. port 57) and the sender is on the same machine then you would create a loopback to the receiver itself. Always use the port specified from the packet and in case of production software would need a check in any case to prevent such a case.

Another reason a packet won't get to destination is the wrong IP address specified in the sender. UDP unlike TCP will attempt to send out a packet even if the address is unreachable and the sender will not receive an error indication. You can check this by printing the address in the receiver as a precaution for debugging.

In the sender you set:

 byte [] IP= { (byte)192, (byte)168, 1, 106 };
 InetAddress address = InetAddress.getByAddress(IP);

but might be simpler to use the address in string form:

 InetAddress address = InetAddress.getByName("192.168.1.106");

In other words, you set target as 192.168.1.106. If this is not the receiver then you won't get the packet.

Here's a simple UDP Receiver that works :

import java.io.IOException;
import java.net.*;

public class Receiver {

    public static void main(String[] args) {
        int port = args.length == 0 ? 57 : Integer.parseInt(args[0]);
        new Receiver().run(port);
    }

    public void run(int port) {    
      try {
        DatagramSocket serverSocket = new DatagramSocket(port);
        byte[] receiveData = new byte[8];
        String sendString = "polo";
        byte[] sendData = sendString.getBytes("UTF-8");

        System.out.printf("Listening on udp:%s:%d%n",
                InetAddress.getLocalHost().getHostAddress(), port);     
        DatagramPacket receivePacket = new DatagramPacket(receiveData,
                           receiveData.length);

        while(true)
        {
              serverSocket.receive(receivePacket);
              String sentence = new String( receivePacket.getData(), 0,
                                 receivePacket.getLength() );
              System.out.println("RECEIVED: " + sentence);
              // now send acknowledgement packet back to sender     
              DatagramPacket sendPacket = new DatagramPacket(sendData, sendData.length,
                   receivePacket.getAddress(), receivePacket.getPort());
              serverSocket.send(sendPacket);
        }
      } catch (IOException e) {
              System.out.println(e);
      }
      // should close serverSocket in finally block
    }
}

After installing antivirus I faced this issue and I noticed that my firewall automatically set as on, Now I just set firewall off and it solved my issue. Hope it will help someone :)

We had a similar situation, but in our case Infosec agreed to allow any to 1, so we didnt had to fix the slave port, rather fixing the master to high level JNLP port 49187 worked ("Configure Global Security" -> "TCP port for JNLP slave agents").

TCP
49187 - Fixed jnlp port
8080 - jenkins http port

Other ports needed to launch slave as a windows service

TCP
135 
139 
445

UDP
137
138

Use this command to find your active zone(s):

firewall-cmd --get-active-zones

It will say either public, dmz, or something else. You should only apply to the zones required.

In the case of public try:

firewall-cmd --zone=public --add-port=2888/tcp --permanent

Then remember to reload the firewall for changes to take effect.

firewall-cmd --reload

Otherwise, substitute public for your zone, for example, if your zone is dmz:

firewall-cmd --zone=dmz --add-port=2888/tcp --permanent

If you can modify the client, then have it print out the remote reference and you will see what port it's using. E.g.

ServerApi server = (ServerApi) registry.lookup(ServerApi.RMI_NAME);
System.out.println("Got server handle " + server);

will produce something like:

Got server handle Proxy[ServerApi,RemoteObjectInvocationHandler[UnicastRef [liveRef: [endpoint:172.17.3.190:9001,objID:[-7c63fea8:...

where you can see the port is 9001. If the remote class is not specifying the port, then it will change across reboots. If you want to use a fixed port then you need to make sure the remote class constructor does something like:

super(rmiPort)

Assume that, if you want to remove NAT rules,

List the appended IPtables using the command below,

# sudo iptables -L -t nat -v

Chain PREROUTING (policy ACCEPT 18 packets, 1382 bytes)
 pkts bytes target     prot opt in     out     source               destination         
    7   420 DNAT       tcp  --  any    any     anywhere             saltmaster           tcp dpt:http to:172.31.5.207:80
    0     0 DNAT       tcp  --  eth0   any     anywhere             anywhere             tcp dpt:http to:172.31.5.207:8080

If you would like to remove the nat rule from the IPtables, just execute the command,

# sudo iptables -F -t nat -v

Flushing chain `PREROUTING'
Flushing chain `INPUT'
Flushing chain `OUTPUT'
Flushing chain `POSTROUTING'

Then, you can verify that,

# sudo iptables -L -t nat -v

The accepted answer doesn't cut it because if a user de-selects a row the list is not updated accordingly.

Here is what I suggest instead:

Private Sub CommandButton2_Click()
    Dim lItem As Long

    For lItem = 0 To ListBox1.ListCount - 1
        If ListBox1.Selected(lItem) = True Then
            MsgBox(ListBox1.List(lItem))
        End If
    Next
End Sub

This is my logic. Set the first of the week to be Monday then calculate what is the day of the week a give day is, then using DateAdd and Case I calculate what the date would have been on the previous Monday of that week.

I added a few to Joel's code.

    import socket,time
    mem1 = 0
    while True:
        try:
                host = socket.gethostbyname("www.google.com") #Change to personal choice of site
                s = socket.create_connection((host, 80), 2)
                s.close()
                mem2 = 1
                if (mem2 == mem1):
                    pass #Add commands to be executed on every check
                else:
                    mem1 = mem2
                    print ("Internet is working") #Will be executed on state change

        except Exception as e:
                mem2 = 0
                if (mem2 == mem1):
                    pass
                else:
                    mem1 = mem2
                    print ("Internet is down")
        time.sleep(10) #timeInterval for checking

I am not sure how this happened but I started to get this error in my internal submit form pages. So when ever I submit something I'm getting this error. But the problem is this website is almost working 5-6 years. I don't remember I made an important change.

None of the solutions worked for me.

I have setup a machine key with the Microsoft script and copied into my web.config

I have executed asp.net regiis script.

aspnet_regiis -ga "IIS APPPOOL\My App Pool"

Also tried to add this code into the page:

enableViewStateMac="false"

still no luck.

Any other idea to solve this issue?

UPDATE:

Finally I solved the issue. I had integrated my angular 4 component into my asp.net website. So I had added base href into my master page. So I removed that code and it is working fine now.

<base href="/" />

You can get ID only after saving, instead you can create a new Guid and assign before saving.

This question has been answered, but maybe this might someone else coming here.

I also had an issue where this is undefined, when I was foolishly trying to destructure the methods of a class when initialising it:

import MyClass from "./myClass"

// 'this' is not defined here:
const { aMethod } = new MyClass()
aMethod() // error: 'this' is not defined

// So instead, init as you would normally:
const myClass = new MyClass()
myClass.aMethod() // OK

It looks like you are calling next even if the scanner no longer has a next element to provide... throwing the exception.

while(!file.next().equals(treasure)){
        file.next();
        }

Should be something like

boolean foundTreasure = false;

while(file.hasNext()){
     if(file.next().equals(treasure)){
          foundTreasure = true;
          break; // found treasure, if you need to use it, assign to variable beforehand
     }
}
    // out here, either we never found treasure at all, or the last element we looked as was treasure... act accordingly

In Git, you cannot commit empty folders, because Git does not actually save folders, only files. You'll have to create some placeholder file inside those directories if you actually want them to be "empty" (i.e. you have no committable content).

I do not think there is a "correct" way.

I would use:

with open ('myfile', 'a') as f: f.write ('hi there\n')

In memoriam Tim Toady.

Use malloc() when you don't know the amount of memory needed during compile time. In case if you have read-only strings then you can use const char* str = "something"; . Note that the string is most probably be stored in a read-only memory location and you'll not be able to modify it. On the other hand if you know the string during compiler time then you can do something like: char str[10]; strcpy(str, "Something"); Here the memory is allocated from stack and you will be able to modify the str. Third case is allocating using malloc. Lets say you don'r know the length of the string during compile time. Then you can do char* str = malloc(requiredMem); strcpy(str, "Something"); free(str);

You can use FutureBuilder widget instead. This takes an argument which must be a Future. Then you can use a snapshot which is the state at the time being of the async call when loging in, once it ends the state of the async function return will be updated and the future builder will rebuild itself so you can then ask for the new state.

FutureBuilder(
  future:  myFutureFunction(),
  builder: (context, AsyncSnapshot<List<item>> snapshot) {
    if (!snapshot.hasData) {
      return Center(
        child: CircularProgressIndicator(),
      );
    } else {
     //Send the user to the next page.
  },
);

Here you have an example on how to build a Future

Future<void> myFutureFunction() async{
 await callToApi();}

As per Where is Maven Installed on Ubuntu it will first create your settings.xml on /usr/share/maven2/, then you can copy to your home folder as jens mentioned

$ cp /usr/share/maven3/conf/settings.xml ~/.m2/settings.xml

As suggested above, i had similar issue with mysql-5.7.18,
i did this in this way

1. Executed this command from "MYSQL_HOME\bin\mysqld.exe --initialize-insecure"
2. then started "MYSQL_HOME\bin\mysqld.exe"
3. Connect workbench to this localhost:3306 with username 'root'
4. then executed this query "SET PASSWORD FOR 'root'@'localhost' = 'root';"

password was also updated successfully.

There is no forumula, as street names and cities are essentially handed out randomly. The address needs to be looked up in a database. Alternatively, you can look up a zip code in a database for the region that the zip code is for.

You didn't mention a country, so I'm going to assume you just want addresses in the USA. There are numerous databases you can use, some free, some not.

You can also use the Google Maps API to have them look up an address in their database for you. That is probably the easiest solution, but requires your application to have a working internet connection at all times.

By using iter builtin:

l = [1, 2, 3]
# i is the first item.
i = iter(l)
next(i)
for d in i:
    print(d)

If you did everything as in above answers, but a menu item is still visible, check that you reference to the unique resource. For instance, in onCreateOptionsMenu or onPrepareOptionsMenu

@Override
public void onPrepareOptionsMenu(Menu menu) {
    super.onPrepareOptionsMenu(menu);
    MenuItem menuOpen = menu.findItem(R.id.menu_open);
    menuOpen.setVisible(false);
}

Ctrl+Click R.id.menu_open and check that it exists only in one menu file. In case when this resource is already used anywhere and loaded in an activity, it will try to hide there.

A solution with a bigger browser support then the flexbox (works in IE=9):

#wrapper {_x000D_

  -ms-transform: scaleY(-1);_x000D_
  transform: scaleY(-1);_x000D_

#wrapper > * {_x000D_
  -webkit-transform: scaleY(-1);_x000D_
  -ms-transform: scaleY(-1);_x000D_
  transform: scaleY(-1);_x000D_
}

<div id="wrapper">_x000D_

        Content to be above in this situation_x000D_
    </div>_x000D_
</div>_x000D_
Other elements

In contrast to the display: table; solution this solution works when .wrapper has any amount of children.

This does not fully answer my original question, but I think it is important to let everyone know what I did and why.

I chose to continue using python 2.7 instead of python 3 because of the prevalence of 2.7 examples and modules on the web in general.

I now use both mysqldb and mysql.connector to connect to MySQL in Python 2.7. Both are great and work well. I think mysql.connector is ultimately better long term however.

Here in your code demo is id where you want to display your result after click event has occur and just nothing.

You can take anything

<p id="demo">

or

<div id="demo"> 

It is just node in a document where you just want to display your result.

I had the same problem, after researching a lot, I finally built a js function to create modals dynamically based on my requirements. Using this function, you can create popups in one line such as:

puyModal({title:'Test Title',heading:'Heading',message:'This is sample message.'})

Or you can use other complex functionality such as iframes, video popups, etc.

Find it on https://github.com/aybhalala/puymodals For demo, go to http://pateladitya.com/puymodals/

Java Language Support extension provides basic features for the Java programming language. Current editing features include:

• Syntax highlighting and brace matching
• Outlining support for quickly collapsing classes and functions
• Dropdown bars listing classes, enums, interfaces, fields, and methods within the current document

And if you wish to contribute then the project has been moved to its own GitHub repository

Try instead of assigning dom properties (which is slow) just pass your value as a parameter to function that actually create your handler:

render: function() {
...
<a style={showStyle} onClick={this.removeTag(i)}></a>
...
removeTag = (customAttribute) => (event) => {
    this.setState({inputVal: customAttribute});
}

if you want, you can use a saveActions plugin. You can reformat file, optimized the imports and more things, it's really customizable and easy to setup.

I don't think there is a SAP parameter for that kind of result. Though the code below will deliver.

LOOP AT intTab.

  AT END OF value.

    result = sy-tabix.

    write result.  

  ENDAT.

ENDLOOP.

The problem with your solution is you're putting a scrollbar around a ListBox where you probably want to put it inside the ListBox.

If you want to force a scrollbar in your ListBox, use the ScrollBar.VerticalScrollBarVisibility attached property.

<ListBox 
    ItemsSource="{Binding}" 
    ScrollViewer.VerticalScrollBarVisibility="Visible">
</ListBox>

Setting this value to Auto will popup the scrollbar on an as needed basis.

You can try

<h3 style="text-align:center;"><iframe src=""></iframe></h3>

For python 2 i did this

print ( time.strftime("%H:%M:%S", time.localtime(time.time())) + "." + str(time.time()).split(".",1)[1])

it prints time "%H:%M:%S" , splits the time.time() to two substrings (before and after the .) xxxxxxx.xx and since .xx are my milliseconds i add the second substring to my "%H:%M:%S"

hope that makes sense :) Example output:

The Problem

The org.apache.commons.lang.StringEscapeUtils.unescapeJava() given here as another answer is really very little help at all.

• It forgets about \0 for null.
• It doesn’t handle octal at all.
• It can’t handle the sorts of escapes admitted by the java.util.regex.Pattern.compile() and everything that uses it, including \a, \e, and especially \cX.
• It has no support for logical Unicode code points by number, only for UTF-16.
• This looks like UCS-2 code, not UTF-16 code: they use the depreciated charAt interface instead of the codePoint interface, thus promulgating the delusion that a Java char is guaranteed to hold a Unicode character. It’s not. They only get away with this because no UTF-16 surrogate will wind up looking for anything they’re looking for.

The Solution

I wrote a string unescaper which solves the OP’s question without all the irritations of the Apache code.

If it helps others, you’re welcome to it — no strings attached. If you improve it, I’d love for you to mail me your enhancements, but you certainly don’t have to.

Some time ago I wrote simple Webcam Capture API which can be used for that. The project is available on Github.

Example code:

Webcam webcam = Webcam.getDefault();
webcam.open();
try {
  ImageIO.write(webcam.getImage(), "PNG", new File("test.png"));
} catch (IOException e) {
  e.printStackTrace();
} finally {
  webcam.close();
}

I suspect you don't actually have that problem - I suspect you've really got:

double a = callSomeFunction();
// Examine a in the debugger or via logging, and decide it's 3669.0

// Now cast
int b = (int) a;
// Now a is 3668

What makes me say that is that although it's true that many decimal values cannot be stored exactly in float or double, that doesn't hold for integers of this kind of magnitude. They can very easily be exactly represented in binary floating point form. (Very large integers can't always be exactly represented, but we're not dealing with a very large integer here.)

I strongly suspect that your double value is actually slightly less than 3669.0, but it's being displayed to you as 3669.0 by whatever diagnostic device you're using. The conversion to an integer value just performs truncation, not rounding - hence the issue.

Assuming your double type is an IEEE-754 64-bit type, the largest value which is less than 3669.0 is exactly

3668.99999999999954525264911353588104248046875

So if you're using any diagnostic approach where that value would be shown as 3669.0, then it's quite possible (probable, I'd say) that this is what's happening.

I just came across this question while searching for the solution for myself. You might consider calling the system beep function by running some kernel32 stuff.

using System.Runtime.InteropServices;
        [DllImport("kernel32.dll")]
        public static extern bool Beep(int freq, int duration);

        public static void TestBeeps()
        {
            Beep(1000, 1600); //low frequency, longer sound
            Beep(2000, 400); //high frequency, short sound
        }

This is the same as you would run powershell:

[console]::beep(1000, 1600)
[console]::beep(2000, 400)

Another Possible solution is to reinstall typings:
This works for me for "angular2": "2.0.0-beta.15"

1. npm clean cache
2. npm install
3. npm install -g typings
4. Delete typings directory from project (Directory wwhere typings modules are installed)
5. typings install
6. npm run

Assuming you want to do it yourself and not rely upon other providers, IP2Nation provides a MySQL database of the mappings which are updated as the regional registries change things around.

The m000493 method seems to perform some kind of XOR encryption. This means that the same method can be used for both encrypting and decrypting the text. All you have to do is reverse m0001cd:

string p0 = Encoding.UTF8.GetString(Convert.FromBase64String("OBFZDT..."));

string result = m000493(p0, "_p0lizei.");
//    result == "gaia^unplugged^Ta..."

with return m0001cd(builder3.ToString()); changed to return builder3.ToString();.

Below code works with autowiring - it is not the shortest version but useful when it should work only with standard spring/mockito jars.

<bean id="dao" class="org.springframework.aop.framework.ProxyFactoryBean">
   <property name="target"> <bean class="org.mockito.Mockito" factory-method="mock"> <constructor-arg value="com.package.Dao" /> </bean> </property>
   <property name="proxyInterfaces"> <value>com.package.Dao</value> </property>
</bean> 

As the error notes, the problem is in the line:

if guess[i] == winning_numbers[i]

The error is that your list indices are out of range--that is, you are trying to refer to some index that doesn't even exist. Without debugging your code fully, I would check the line where you are adding guesses based on input:

for i in range(tickets):
    bubble = input("What numbers do you want to choose for ticket #"+str(i+1)+"?\n").split(" ")
    guess.append(bubble)
print(bubble)

The size of how many guesses you are giving your user is based on

# Prompts the user to enter the number of tickets they wish to play.
tickets = int(input("How many lottery tickets do you want?\n"))

So if the number of tickets they want is less than 5, then your code here

for i in range(5):

if guess[i] == winning_numbers[i]:
    match = match+1

return match

will throw an error because there simply aren't that many elements in the guess list.

Indeed a one-hot encoder will work just fine here, convert any string and numerical categorical variables you want into 1's and 0's this way and random forest should not complain.

If you don't have a company, leave your name, it doesn't matter as long as both bundle id in info.plist file and the one you've submitted in iTunes Connect match.

In Bundle ID Suffix you should write full name of bundle ID.

Example:

Bundle ID suffix = thebestapp (NOT CORRECT!!!!)

Bundle ID suffix = com.awesomeapps.thebestapp (CORRECT!!)

The reason for this is explained in the Developer Portal:

The App ID string contains two parts separated by a period (.) — an App ID Prefix (your Team ID by default, e.g. ABCDE12345), and an App ID Suffix (a Bundle ID search string, e.g. com.mycompany.appname). [emphasis added]

So in this case the suffix is the full string com.awesomeapps.thebestapp.

One way is to use the lattice package and xyplot():

R> DF <- data.frame(x=1:10, y=rnorm(10)+5, 
+>                  z=sample(letters[1:3], 10, replace=TRUE))
R> DF
    x       y z
1   1 3.91191 c
2   2 4.57506 a
3   3 3.16771 b
4   4 5.37539 c
5   5 4.99113 c
6   6 5.41421 a
7   7 6.68071 b
8   8 5.58991 c
9   9 5.03851 a
10 10 4.59293 b
R> with(DF, xyplot(y ~ x, group=z))

By giving explicit grouping information via variable z, you obtain different colors. You can specify colors etc, see the lattice documentation.

Because z here is a factor variable for which we obtain the levels (== numeric indices), you can also do

R> with(DF, plot(x, y, col=z))

but that is less transparent (to me, at least :) then xyplot() et al.

Not exactly answering your question, but if you could move away from your self-made wrapper then there is Simple Logging Facade for Java (SLF4J) which Hibernate has now switched to (instead of commons logging).

SLF4J suffers from none of the class loader problems or memory leaks observed with Jakarta Commons Logging (JCL).

SLF4J supports JDK logging, log4j and logback. So then it should be fairly easy to switch from log4j to logback when the time is right.

Edit: Aplogies that I hadn't made myself clear. I was suggesting using SLF4J to isolate yourself from having to make a hard choice between log4j or logback.

If you are looking for a .NET Core compatible way, use

System.AppContext.BaseDirectory

This was introduced in .NET Framework 4.6 and .NET Core 1.0 (and .NET Standard 1.3). See: AppContext.BaseDirectory Property.

According to this page,

This is the prefered replacement for AppDomain.CurrentDomain.BaseDirectory in .NET Core

This eventually helped me:

    var x = 0;
    var buttonText = 'LOADING';

    $('#startbutton').click(function(){
        $(this).text(buttonText);
        window.setTimeout(addDotToButton,2000);
    })

    function addDotToButton(){
        x++;
        buttonText += '.';
        $('#startbutton').text(buttonText);

        if (x < 4) window.setTimeout(addDotToButton, 2000);
        else location.reload(true);
    }

Is it possible you have a race condition where another thread or process is adding files to the directory:

The sequence would be:

Deleter process A:

1. Empty the directory
2. Delete the (now empty) directory.

If someone else adds a file between 1 & 2, then maybe 2 would throw the exception listed?

DateTime itself contains no real timezone information. It may know if it's UTC or local, but not what local really means.

DateTimeOffset is somewhat better - that's basically a UTC time and an offset. However, that's still not really enough to determine the timezone, as many different timezones can have the same offset at any one point in time. This sounds like it may be good enough for you though, as all you've got to work with when parsing the date/time is the offset.

The support for time zones as of .NET 3.5 is a lot better than it was, but I'd really like to see a standard "ZonedDateTime" or something like that - a UTC time and an actual time zone. It's easy to build your own, but it would be nice to see it in the standard libraries.

EDIT: Nearly four years later, I'd now suggest using Noda Time which has a rather richer set of date/time types. I'm biased though, as the main author of Noda Time :)

Local variables do not get default values. Their initial values are undefined without assigning values by some means. Before you can use local variables they must be initialized.

There is a big difference when you declare a variable at class level (as a member, i.e., as a field) and at the method level.

If you declare a field at the class level they get default values according to their type. If you declare a variable at the method level or as a block (means any code inside {}) do not get any values and remain undefined until somehow they get some starting values, i.e., some values assigned to them.

If you are accessing your repositories over the SSH protocol, you will receive a warning message each time your client connects to a new IP address for github.com. As long as the IP address from the warning is in the range of IP addresses , you shouldn't be concerned. Specifically, the new addresses that are being added this time are in the range from 192.30.252.0 to 192.30.255.255. The warning message looks like this:

Warning: Permanently added the RSA host key for IP address '$IP' to the list of

You might try using:

li {list-style-position: inside; }

But I can't remember if that adjusts the space, or changes where the space occurs.

The above doesn't seem to make any substantial difference. There doesn't seem to be any way to decrease the space between the list-style-type marker and the text, though it can be increased using margin-left or text-indent.

Sorry I can't be of more use.

Just out of curiosity, how about 'faking' the bullet with a background image?

ul {list-style-type: none;
    margin: 0;
    padding: 0;
}

ul li {background: #fff url(path/to/bullet-image.png) 0 50% no-repeat;
       margin: 0;
       padding: 0 0 0 10px; /* change 10px to whatever you feel best suits you */
}

It might allow for more fine-tuning.

Assume your file looks like this and is named test.txt (space delimited):

1 2
3 4
5 6
7 8

Then:

#!/usr/bin/python

import numpy as np
import matplotlib.pyplot as plt

with open("test.txt") as f:
    data = f.read()

data = data.split('\n')

x = [row.split(' ')[0] for row in data]
y = [row.split(' ')[1] for row in data]

fig = plt.figure()

ax1 = fig.add_subplot(111)

ax1.set_title("Plot title...")    
ax1.set_xlabel('your x label..')
ax1.set_ylabel('your y label...')

ax1.plot(x,y, c='r', label='the data')

leg = ax1.legend()

plt.show()

I find that browsing the gallery of plots on the matplotlib site helpful for figuring out legends and axes labels.

use getBoundingClientRect if $el is the actual DOM object:

var top = $el.getBoundingClientRect().top;

JSFiddle

Fiddle will show that this will get the same value that jquery's offset top will give you

Edit: as mentioned in comments this does not account for scrolled content, below is the code that jQuery uses

https://github.com/jquery/jquery/blob/master/src/offset.js (5/13/2015)

offset: function( options ) {
    //...

    var docElem, win, rect, doc,
        elem = this[ 0 ];

    if ( !elem ) {
        return;
    }

    rect = elem.getBoundingClientRect();

    // Make sure element is not hidden (display: none) or disconnected
    if ( rect.width || rect.height || elem.getClientRects().length ) {
        doc = elem.ownerDocument;
        win = getWindow( doc );
        docElem = doc.documentElement;

        return {
            top: rect.top + win.pageYOffset - docElem.clientTop,
            left: rect.left + win.pageXOffset - docElem.clientLeft
        };
    }
}

For example, you can try:

//If you want to get user, you need start query in your mysql:
SELECT user(); // output your user: root@localhost
SELECT system_user(); // --

//If you want to get port your "mysql://user:pass@hostname:port/db"
SELECT @@port; //3306 is default

//If you want hostname your db, you can execute query
SELECT @@hostname;

I'm using a newer version of the SPO Management Shell. For me to get the error to go away, I changed my Import-Module statement to use:

Import-Module Microsoft.Online.SharePoint.PowerShell -DisableNameChecking;

I also use the newer command:

Connect-SPOService

Convert a string date to java.sql.Date

String fromDate = "19/05/2009";
DateFormat df = new SimpleDateFormat("dd/MM/yyyy");
java.util.Date dtt = df.parse(fromDate);
java.sql.Date ds = new java.sql.Date(dtt.getTime());
System.out.println(ds);//Mon Jul 05 00:00:00 IST 2010

Oracle stores only the fractions up to second in a DATE field.

Use TIMESTAMP instead:

SELECT  TO_TIMESTAMP('2004-09-30 23:53:48,140000000', 'YYYY-MM-DD HH24:MI:SS,FF9')
FROM    dual

, possibly casting it to a DATE then:

SELECT  CAST(TO_TIMESTAMP('2004-09-30 23:53:48,140000000', 'YYYY-MM-DD HH24:MI:SS,FF9') AS DATE)
FROM    dual

The problem with the Automation API solution is, that it required a reference to the Framework assembly UIAutomationProvider as project/package dependency.

An alternative is to emulate the behaviour. In the following there is my extended solution which also condiders the MVVM-pattern with its bound commands - implemented as extension method:

public static class ButtonExtensions
{
    /// <summary>
    /// Performs a click on the button.<br/>
    /// This is the WPF-equivalent of the Windows Forms method "<see cref="M:System.Windows.Forms.Button.PerformClick" />".
    /// <para>This simulates the same behaviours as the button was clicked by the user by keyboard or mouse:<br />
    /// 1. The raising the ClickEvent.<br />
    /// 2.1. Checking that the bound command can be executed, calling <see cref="ICommand.CanExecute" />, if a command is bound.<br />
    /// 2.2. If command can be executed, then the <see cref="ICommand.Execute(object)" /> will be called and the optional bound parameter is p
    /// </para>
    /// </summary>
    /// <param name="sourceButton">The source button.</param>
    /// <exception cref="ArgumentNullException">sourceButton</exception>
    public static void PerformClick(this Button sourceButton)
    {
        // Check parameters
        if (sourceButton == null)
            throw new ArgumentNullException(nameof(sourceButton));

        // 1.) Raise the Click-event
        sourceButton.RaiseEvent(new RoutedEventArgs(System.Windows.Controls.Primitives.ButtonBase.ClickEvent));

        // 2.) Execute the command, if bound and can be executed
        ICommand boundCommand = sourceButton.Command;
        if (boundCommand != null)
        {
            object parameter = sourceButton.CommandParameter;
            if (boundCommand.CanExecute(parameter) == true)
                boundCommand.Execute(parameter);
        }
    }
}

If your only goal by removing the listeners is to stop them from running, you can add an event listener to the window capturing and canceling all events of the given type:

window.addEventListener(type, function (event) {
    event.stopPropagation();
}, true);

Passing in true for the third parameter causes the event to be captured on the way down. Stopping propagation means that the event never reaches the listeners that are listening for it.

Keep in mind though that this has very limited use as you can't add new listeners for the given type (they will all be blocked). There are ways to get around this somewhat, e.g., by firing a new kind of event that only your listeners would know to listen for. Here is how you can do that:

window.addEventListener('click', function (event) {
    // (note: not cross-browser)
    var event2 = new CustomEvent('click2', {detail: {original: event}});
    event.target.dispatchEvent(event2);
    event.stopPropagation();
}, true);

element.addEventListener('click2', function(event) {
    event = event.detail && event.detail.original ?
        event.detail.original :
        event;
    // ... do something with event ...
});

However, note that this may not work as well for fast events like mousemove, given that the re-dispatching of the event introduces a delay.

Better would be to just keep track of the listeners added in the first place, as outlined in Martin Wantke's answer, if you need to do this.

This can be achieved by attaching a "tabindex" to an element. This will make that element "clickable". You can then use :focus to select your hidden div as follows...

.clicker {_x000D_
width:100px;_x000D_
height:100px;_x000D_
background-color:blue;_x000D_
outline:none;_x000D_
cursor:pointer;_x000D_
}_x000D_
_x000D_
.hiddendiv{_x000D_
display:none;_x000D_
height:200px;_x000D_
background-color:green;_x000D_
}_x000D_
_x000D_
.clicker:focus + .hiddendiv{_x000D_
display:block;_x000D_
}

<html>_x000D_
<head>_x000D_
</head>_x000D_
<body>_x000D_
_x000D_
<div>_x000D_
<div class="clicker" tabindex="1">Click me</div>_x000D_
<div class="hiddendiv"></div>_x000D_
</div>_x000D_
_x000D_
</body>_x000D_
_x000D_
</html>

The + selector will select the nearest element AFTER the "clicker" div. You can use other selectors but I believe there is no current way to select an element that is not a sibling or child.

A FragmentActivity is a subclass of Activity that was built for the Android Support Package.

The FragmentActivity class adds a couple new methods to ensure compatibility with older versions of Android, but other than that, there really isn't much of a difference between the two. Just make sure you change all calls to getLoaderManager() and getFragmentManager() to getSupportLoaderManager() and getSupportFragmentManager() respectively.

Try this - You have to import java.util.regex.*;

    Pattern pattern = Pattern.compile("\\s+");
    Matcher matcher = pattern.matcher(string);
    boolean check = matcher.find();
    String str = matcher.replaceAll(" ");

Where string is your string on which you need to remove duplicate white spaces

import operator
sorted_x = sorted(x, key=operator.attrgetter('score'))

if you want to sort x in-place, you can also:

x.sort(key=operator.attrgetter('score'))

If I want a 1x3 array, or 3x1 array:

import numpy as np
row_arr = np.array([1,2,3]).reshape((1,3))
col_arr = np.array([1,2,3]).reshape((3,1)))

Check your work:

row_arr.shape  #returns (1,3)
col_arr.shape  #returns (3,1)

I found a lot of answers here are helpful, but much too complicated for me. In practice I come back to shape and reshape and the code is readable: very simple and explicit.

I can confirm ckramer that jQuery's ready event works in IE and FireFox. Here's a sample:

<html>
<head>
    <title>Test Page</title>
    <script src="http://code.jquery.com/jquery-latest.js" type="text/javascript"></script>
    <script type="text/javascript">
            $(document).ready(function () {
               var d = new Date();
               $('#test').html( "Hi at " + d.toString() );
            });
    </script>
</head>
<body>
    <div id="test"></div>
    <div>
        <a href="http://www.google.com">Go!</a>
    </div>
</body>
</html>

    //Setting Limit for Paging
    if ($limit != '' && $offset == 0) {
        $this->db->limit($limit);

You need to have

#include <string>

in the header file too.The forward declaration on it's own doesn't do enough.

Also strongly consider header guards for your header files to avoid possible future problems as your project grows. So at the top do something like:

#ifndef THE_FILE_NAME_H
#define THE_FILE_NAME_H

/* header goes in here */

#endif

This will prevent the header file from being #included multiple times, if you don't have such a guard then you can have issues with multiple declarations.

if (isset($_SERVER['HTTPS'])){
    echo "https://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]$_SERVER[QUERY_STRING]";
}else{
    echo "http://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]$_SERVER[QUERY_STRING]";
}

I did this in my project and it works like a charm

Date now = new Date();
System.out.println(now);
TimeZone.setDefault(TimeZone.getTimeZone("UTC")); // The magic is here
System.out.println(now);

Join on one-to-many relation in JPQL looks as follows:

select b.fname, b.lname from Users b JOIN b.groups c where c.groupName = :groupName 

When several properties are specified in select clause, result is returned as Object[]:

Object[] temp = (Object[]) em.createNamedQuery("...")
    .setParameter("groupName", groupName)
    .getSingleResult(); 
String fname = (String) temp[0];
String lname = (String) temp[1];

By the way, why your entities are named in plural form, it's confusing. If you want to have table names in plural, you may use @Table to specify the table name for the entity explicitly, so it doesn't interfere with reserved words:

@Entity @Table(name = "Users")     
public class User implements Serializable { ... }

java.sql.Timestamp.from (
    LocalDate.of ( 2007 , 9 , 23 )
             .atStartOfDay( ZoneId.of ( "America/Montreal" ) )
             .toInstant()
)

java.time

Let’s update this page by showing code using the java.time framework built into Java 8 and later.

These new classes are inspired by Joda-Time, defined by JSR 310, and extended by the ThreeTen-Extra project. They supplant the notoriously troublesome old date-time classes bundled with early versions of Java.

In java.time, an Instant is a moment on the timeline in UTC. A ZonedDateTime is an Instant adjusted into a time zone (ZoneId).

Time zone is crucial here. A date of September 23, 2007 cannot be translated to a moment on the timeline without applying a time zone. Consider that a new day dawns earlier in Paris than in Montréal where it is still “yesterday”.

Also, a java.sql.Timestamp represents both a date and time-of-day. So we must inject a time-of-day to go along with the date. We assume you want the first moment of the day as the time-of-day. Note that this is not always the time 00:00:00.0 because of Daylight Saving Time and possibly other anomalies.

Note that unlike the old java.util.Date class, and unlike Joda-Time, the java.time types have a resolution of nanoseconds rather than milliseconds. This matches the resolution of java.sql.Timestamp.

Note that the java.sql.Timestamp has a nasty habit of implicitly applying your JVM’s current default time zone to its date-time value when generating a string representation via its toString method. Here you see my America/Los_Angeles time zone applied. In contrast, the java.time classes are more sane, using standard ISO 8601 formats.

LocalDate d = LocalDate.of ( 2007 , 9 , 23 ) ;
ZoneId z = ZoneId.of ( "America/Montreal" ) ;
ZonedDateTime zdt = d.atStartOfDay( z ) ;
Instant instant = zdt.toInstant() ;
java.sql.Timestamp ts = java.sql.Timestamp.from ( instant ) ;

Dump to console.

System.out.println ( "d: " + d + " = zdt: " + zdt + " = instant: " + instant + " = ts: " + ts );

When run.

d: 2007-09-23 = zdt: 2007-09-23T00:00-04:00[America/Montreal] = instant: 2007-09-23T04:00:00Z = ts: 2007-09-22 21:00:00.0

By the way, as of JDBC 4.2, you can use the java.time types directly. No need for java.sql.Timestamp.

• PreparedStatement.setObject
• ResultSet.getObject

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, Java SE 10, Java SE 11, and later - Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Most of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android (<26), the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

Add the "extern" keyword to the function definitions in point.h

Yes, use INSERT ... ON DUPLICATE KEY UPDATE id=id (it won't trigger row update even though id is assigned to itself).

If you don't care about errors (conversion errors, foreign key errors) and autoincrement field exhaustion (it's incremented even if the row is not inserted due to duplicate key), then use INSERT IGNORE.

Use Elastic Load Balacing, it supports SSL termination at the Load Balancer, including offloading SSL decryption from application instances and providing centralized management of SSL certificates.

In my case what removed this message was (After updating everything) deleting the emulator and creating a new one. Manually updating the adb didn't solved this for. Nor updating via the Android studio Gui. In my case it seems that since the emulator was created with "old" components it keep showing the message. I had three emulators, just deleted them all and created a new one. For my surprise when it started the message was no more.

Cannot tell if performance is better or not. The message just didn't came up. Also I have everything updated to the latest (emulators and sdk).

import json
row = [1L,[0.1,0.2],[[1234L,1],[134L,2]]]

You can read value by

searchTxt.value

function searchURL() {
   let txt = searchTxt.value;
   console.log(txt);
   // window.location = "http://www.myurl.com/search/" + txt; ...
}

document.querySelector('.search').addEventListener("click", ()=>searchURL());

<input name="searchTxt" type="text" maxlength="512" id="searchTxt" class="searchField"/>

<button class="search">Search</button>

UPDATE

I see many downvotes but any comments - however (for future readers) actually this solution works

The view (blade template): Inside the loop you can retrieve whatever column you looking for

 @foreach ($products as $product)
   {{$product->sku}}
 @endforeach

You'll want to use a number of layout managers to help you achieve the basic results you want.

Check out A Visual Guide to Layout Managers for a comparision.

You could use a GridBagLayout but that's one of the most complex (and powerful) layout managers available in the JDK.

You could use a series of compound layout managers instead.

I'd place the graphics component and text area on a single JPanel, using a BorderLayout, with the graphics component in the CENTER and the text area in the SOUTH position.

I'd place the text field and button on a separate JPanel using a GridBagLayout (because it's the simplest I can think of to achieve the over result you want)

I'd place these two panels onto a third, master, panel, using a BorderLayout, with the first panel in the CENTER and the second at the SOUTH position.

But that's me

Here is my fancy version:

import org.gradle.api.tasks.testing.logging.TestExceptionFormat

tasks.withType(Test) {
    testLogging {
        // set options for log level LIFECYCLE
        events TestLogEvent.FAILED,
               TestLogEvent.PASSED,

        info.exceptionFormat = debug.exceptionFormat

        afterSuite { desc, result ->

                def output = "Results: ${result.resultType} (${result.testCount} tests, ${result.successfulTestCount} passed, ${result.failedTestCount} failed, ${result.skippedTestCount} skipped)"
                def startItem = '|  ', endItem = '  |'
                def repeatLength = startItem.length() + output.length() + endItem.length()
                println('\n' + ('-' * repeatLength) + '\n' + startItem + output + endItem + '\n' + ('-' * repeatLength))
            }
        }
    }

if pptCreator is a function/procedure in the same file, you could call it as below

call pptCreator()

When generating mapping files using doctrine I ran into same issue. I fixed it by removing all comments that some fields had in the database.

While not strictly serialization, json may be reasonable approach here. That will handled nested dicts and lists, and data as long as your data is "simple": strings, and basic numeric types.

By default, CORS does not include cookies on cross-origin requests. This is different from other cross-origin techniques such as JSON-P. JSON-P always includes cookies with the request, and this behavior can lead to a class of vulnerabilities called cross-site request forgery, or CSRF.

In order to reduce the chance of CSRF vulnerabilities in CORS, CORS requires both the server and the client to acknowledge that it is ok to include cookies on requests. Doing this makes cookies an active decision, rather than something that happens passively without any control.

The client code must set the withCredentials property on the XMLHttpRequest to true in order to give permission.

However, this header alone is not enough. The server must respond with the Access-Control-Allow-Credentials header. Responding with this header to true means that the server allows cookies (or other user credentials) to be included on cross-origin requests.

You also need to make sure your browser isn't blocking third-party cookies if you want cross-origin credentialed requests to work.

Note that regardless of whether you are making same-origin or cross-origin requests, you need to protect your site from CSRF (especially if your request includes cookies).

You want your if check to be:

{% if not loop.last %}
    ,
{% endif %}

Note that you can also shorten the code by using If Expression:

{{ ", " if not loop.last else "" }}

I think you should casting variable or use Integer class by call out method doubleValue().

You should never write code that concatenates SQL and parameters as string - this opens up your code to SQL injection which is a really serious security problem.

Use bind params - for a nice howto see here...

From the Android Developers page,

onPause():

Called when the system is about to start resuming a previous activity. This is typically used to commit unsaved changes to persistent data, stop animations and other things that may be consuming CPU, etc. Implementations of this method must be very quick because the next activity will not be resumed until this method returns. Followed by either onResume() if the activity returns back to the front, or onStop() if it becomes invisible to the user.

onStop():

Called when the activity is no longer visible to the user, because another activity has been resumed and is covering this one. This may happen either because a new activity is being started, an existing one is being brought in front of this one, or this one is being destroyed. Followed by either onRestart() if this activity is coming back to interact with the user, or onDestroy() if this activity is going away.

Now suppose there are three Activities and you go from A to B, then onPause of A will be called now from B to C, then onPause of B and onStop of A will be called.

The paused Activity gets a Resume and Stopped gets Restarted.

When you call this.finish(), onPause-onStop-onDestroy will be called. The main thing to remember is: paused Activities get Stopped and a Stopped activity gets Destroyed whenever Android requires memory for other operations.

I hope it's clear enough.

Expanding on plowman's answer, here is the non-deprecated version of changing the background image with java.

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Bitmap bmp = BitmapFactory.decodeResource(getResources(),
            R.drawable.texture);
    BitmapDrawable bitmapDrawable = new BitmapDrawable(getResources(),bmp);
    bitmapDrawable.setTileModeXY(Shader.TileMode.REPEAT,
            Shader.TileMode.REPEAT);
    setBackground(bitmapDrawable);
}

Try this

<div id="divRegister"></div>

$(document).ready(function() {
location.hash = "divRegister";
});

I have python 2.7.13 and 3.6.2 both installed. Install Anaconda for python 3 first and then you can use conda syntax to get 2.7. My install used: conda create -n py27 python=2.7.13 anaconda

Your foldername is scripts ?

I appreciate this question and all the info with it. I have something in mind that's kind of a question and an answer when it comes to String.Index.

I'm trying to see if there is an O(1) way to access a Substring (or Character) inside a String because string.index(startIndex, offsetBy: 1) is O(n) speed if you look at the definition of index function. Of course we can do something like:

let characterArray = Array(string)

then access any position in the characterArray however SPACE complexity of this is n = length of string, O(n) so it's kind of a waste of space.

I was looking at Swift.String documentation in Xcode and there is a frozen public struct called Index. We can initialize is as:

let index = String.Index(encodedOffset: 0)

Then simply access or print any index in our String object as such:

print(string[index])

Note: be careful not to go out of bounds`

This works and that's great but what is the run-time and space complexity of doing it this way? Is it any better?

This should do it:

#!/usr/local/cpython-2.7/bin/python  # offer users choice for how large of a song list they want to create # in order to determine (roughly) how many songs to copy print "\nHow much space should the random song list occupy?\n" print "1. 100Mb" print "2. 250Mb\n"  tSizeAns = int(raw_input())  if tSizeAns == 1:     tSize = "100Mb" elif tSizeAns == 2:     tSize = "250Mb" else:     tSize = "100Mb"    # in case user fails to enter either a 1 or 2  print "\nYou  want to create a random song list that is {}.".format(tSize) 

BTW, in case you're open to moving to Python 3.x, the differences are slight:

#!/usr/local/cpython-3.3/bin/python  # offer users choice for how large of a song list they want to create # in order to determine (roughly) how many songs to copy print("\nHow much space should the random song list occupy?\n") print("1. 100Mb") print("2. 250Mb\n")  tSizeAns = int(input())  if tSizeAns == 1:     tSize = "100Mb" elif tSizeAns == 2:     tSize = "250Mb" else:     tSize = "100Mb"    # in case user fails to enter either a 1 or 2  print("\nYou want to create a random song list that is {}.".format(tSize))

A simple comparison between del and pop():

import timeit
code = """
results = {'A': 1, 'B': 2, 'C': 3}
del results['A']
del results['B']
"""
print timeit.timeit(code, number=100000)
code = """
results = {'A': 1, 'B': 2, 'C': 3}
results.pop('A')
results.pop('B')
"""
print timeit.timeit(code, number=100000)

result:

0.0329667857143
0.0451040902256

So, del is faster than pop().

fwiw, this didn't work for me until I had this in the ajax call:

contentType: "application/json; charset=utf-8",

using Asp.Net MVC 4.

Just the thread.

Encountered exactly same issue.

To me, the issue is solved by TTTAttributedLabel's

method, as it provide accurate result.

Here's an example that uses 3 different types of parameters.

def func(required_arg, *args, **kwargs):
    # required_arg is a positional-only parameter.
    print required_arg

    # args is a tuple of positional arguments,
    # because the parameter name has * prepended.
    if args: # If args is not empty.
        print args

    # kwargs is a dictionary of keyword arguments,
    # because the parameter name has ** prepended.
    if kwargs: # If kwargs is not empty.
        print kwargs

>>> func()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: func() takes at least 1 argument (0 given)

>>> func("required argument")
required argument

>>> func("required argument", 1, 2, '3')
required argument
(1, 2, '3')

>>> func("required argument", 1, 2, '3', keyword1=4, keyword2="foo")
required argument
(1, 2, '3')
{'keyword2': 'foo', 'keyword1': 4}

They do different things. exec replaces the current process with the new process and never returns. system invokes another process and returns its exit value to the current process. Using backticks invokes another process and returns the output of that process to the current process.

jackson-annotations provides @JsonFormat which can handle a lot of customizations without the need to write the custom serializer.

For example, requesting a STRING shape for a field with numeric type will output the numeric value as string

public class Person {
    public String name;
    public int age;
    @JsonFormat(shape = JsonFormat.Shape.STRING)
    public int favoriteNumber;
}

will result in the desired output

{"name":"Joe","age":25,"favoriteNumber":"123"}

Here is the solution.

The HTML:

<table cellspacing="0" cellpadding="0">
    <tr>
        <td>
            123
        </td>
    </tr>
</table>

The CSS:

table { 
      border-spacing:0; 
      border-collapse:collapse;   
    }

Hope this helps.

EDIT

td, th {padding:0}

Since I link with gcc why ld is being called, as the error message suggests?

gcc calls ld internally when it is in linking mode.

See my jsFiddle here: http://jsfiddle.net/fuDBL/

Whenever you change the email field, the link is updated automatically. This requires a small amount of jQuery. So now your form will work as needed, but your link will be updated dynamically so that when someone clicks on it, it contains what they entered in the email field. You should validate the input on the receiving page.

$('input[name="email"]').change(function(){
  $('#regLink').attr('href')+$('input[name="email"]').val();
});

this line should work for your 3 examples:

sed -r 's#\?(page)=([^&]*)&#/\1/\2#g' a.txt

• I used -r to save some escaping .
• the line should be generic for your one, two three case. you don't have to do the sub 3 times

test with your example (a.txt):

kent$  echo "?page=one&
?page=two&
?page=three&"|sed -r 's#\?(page)=([^&]*)&#/\1/\2#g'
/page/one
/page/two
/page/three

Sometimes we forgot the pulling and did lots of works in the local environment.

If someone want to push without pull,

git push --force

is working. This is not recommended when working with other people, but when your work is a simple thing or a personal toy project, it will be a quick solution.

If you have have open procedure with using sp_helptext then just copy all text in new sql query and press ctrl+h button use regular expression to replace and put ^\n in find field replace with blank . for more detail check image.enter image description here

I know this is not directly answering the question at hand but for anyone that comes upon this question who is using WSL running Docker for windows and cmder or conemu.

The trick is not to use Docker which is installed on windows at /mnt/c/Program Files/Docker/Docker/resources/bin/docker.exe but rather to install the ubuntu/linux Docker. It's worth pointing out that you can't run Docker itself from within WSL but you can connect to Docker for windows from the linux Docker client.

Install Docker on Linux

sudo apt-get install apt-transport-https ca-certificates curl software-properties-common
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
sudo apt-get update
sudo apt-get install docker-ce

Connect to Docker for windows on the port 2375 which needs to be enabled from the settings in docker for windows.

docker -H localhost:2375 run -it -v /mnt/c/code:/var/app -w "/var/app" centos:7

Or set the docker_host variable which will allow you to omit the -H switch

export DOCKER_HOST=tcp://localhost:2375

You should now be able to connect interactively with a tty terminal session.

Check out the implode() function as an alternative. This will convert the array into a list. The first param is how you want the items separated. Here I have used a comma with a space after it.

$invite = implode(', ', $_POST['invite']);
echo $invite;

None of these worked for me. I have pod version 1.5.3 and the correct method was to remove the pods that were not longer needed from the Podfile and then run:

pod update

This updates your Podfile.lock file from your Podfile, removes libraries that have been removed and updates all of your libraries.

Funnily enough, adjusting the padding seems to do it.

.arrow {
  border: solid rgb(2, 0, 0);
  border-width: 0 3px 3px 0;
  display: inline-block;
}

.first{
  padding: 2vh;
}

.second{
  padding: 4vh;
}

.left {
    transform: rotate(135deg);
    -webkit-transform: rotate(135deg);
 }

<i class="arrow first left"></i>
<i class="arrow second left"></i>

Below is the script to check the OS distribution and create User if not exists and do nothing if user exists.

#!/bin/bash

# Detecting OS Ditribution
if [ -f /etc/os-release ]; then
    . /etc/os-release
    OS=$NAME
elif type lsb_release >/dev/null 2>&1; then
OS=$(lsb_release -si)
elif [ -f /etc/lsb-release ]; then
    . /etc/lsb-release
    OS=$DISTRIB_ID
else
    OS=$(uname -s)
fi

 echo "$OS"

 user=$(cat /etc/passwd | egrep -e ansible | awk -F ":" '{ print $1}')

 #Adding User based on The OS Distribution
 if [[ $OS = *"Red Hat"* ]] || [[ $OS = *"Amazon Linux"* ]] || [[ $OS = *"CentOS"*  
]] && [[ "$user" != "ansible" ]];then
 sudo useradd ansible

elif [ "$OS" =  Ubuntu ] && [ "$user" != "ansible" ]; then
sudo adduser --disabled-password --gecos "" ansible
else
  echo "$user is already exist on $OS"
 exit
fi

This is the kind of thing you really shouldn't do with a regular expression. Just parse the string one character at a time, keeping track of opening/closing parentheses.

If this is all you're looking for, you definitely don't need a full-blown C++ grammar lexer/parser. If you want practice, you can write a little recursive-decent parser, but even that's a bit much for just matching parentheses.

In general, you must have a file handle before opening the stream. You have a fileOutputStream handle before createNewFile() in the else block. The stream does not create the file if it doesn't exist.

Not really android specific, but that's a lot IO for this purpose. What if you do many "write" operations one after another? You will be reading the entire contents and writing the entire contents, taking time, and more importantly, battery life.

I suggest using java.io.RandomAccessFile, seek()'ing to the end, then writeChars() to append. It will be much cleaner code and likely much faster.

GLib is a portability/utility library for C which forms the basis of the GTK+ graphical toolkit. It can be used as a standalone library.

It contains portable wrappers for managing directories. See Glib File Utilities documentation for details.

Personally, I wouldn't even consider writing large amounts of C-code without something like GLib behind me. Portability is one thing, but it's also nice to get data structures, thread helpers, events, mainloops etc. for free

Jikes, I'm almost starting to sound like a sales guy :) (don't worry, glib is open source (LGPL) and I'm not affiliated with it in any way)

The standard way is to use format string modifiers. These format string methods are available in most programming languages (via the sprintf function in c for example) and are a handy tool to know about.

To output a string of length 5:

... in Python 3.5 and above:

i = random.randint(0, 99999)
print(f'{i:05d}')

... Python 2.6 and above:

print '{0:05d}'.format(i)

... before Python 2.6:

print "%05d" % i

See: https://docs.python.org/3/library/string.html

In my case, this happened because of sudden shutdown of the system. I followed these steps:

1. Close Android Studio
2. Go to

C:\Users\my_user_name.AndroidStudio4.0\system\caches

3. Delete "caches" folder
4. Relaunch Android Studio

There is a special identifier that one can use in a formula to mean all the variables, it is the . identifier.

y <- c(1,4,6)
d <- data.frame(y = y, x1 = c(4,-1,3), x2 = c(3,9,8), x3 = c(4,-4,-2))
mod <- lm(y ~ ., data = d)

You can also do things like this, to use all variables but one (in this case x3 is excluded):

mod <- lm(y ~ . - x3, data = d)

Technically, . means all variables not already mentioned in the formula. For example

lm(y ~ x1 * x2 + ., data = d)

where . would only reference x3 as x1 and x2 are already in the formula.

You can even use a version range with pip install command. Something like this:

pip install 'stevedore>=1.3.0,<1.4.0'

And if the package is already installed and you want to downgrade it add --force-reinstall like this:

pip install 'stevedore>=1.3.0,<1.4.0' --force-reinstall

Once I found an xsd link on the top of the wsdl. Like this wsdl example from the web, you can see a link xsd1. The server has to be running to see it.

<?xml version="1.0"?>
<definitions name="StockQuote"
             targetNamespace="http://example.com/stockquote.wsdl"
             xmlns:tns="http://example.com/stockquote.wsdl"
             xmlns:xsd1="http://example.com/stockquote.xsd"
             xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/"
             xmlns="http://schemas.xmlsoap.org/wsdl/">

you could try in this way: get the integer value of the double, subtract this from the original double value, define a rounding range and tests if the absolute number of the new double value(without the integer part) is larger or smaller than your defined range. if it is smaller you can intend it it is an integer value. Example:

public final double testRange = 0.2;

public static boolean doubleIsInteger(double d){
    int i = (int)d;
    double abs = Math.abs(d-i);
    return abs <= testRange;
}

If you assign to d the value 33.15 the method return true. To have better results you can assign lower values to testRange (as 0.0002) at your discretion.

In your last block you have a comma after 'lang', followed immediately with a function. This is not valid json.

EDIT

It appears that the readme was incorrect. I had to to pass an array with the string 'twitter'.

var converter = new Showdown.converter({extensions: ['twitter']}); converter.makeHtml('whatever @meandave2020'); // output "<p>whatever <a href="http://twitter.com/meandave2020">@meandave2020</a></p>" 

I submitted a pull request to update this.

If You want your upper axis to be a function of the lower axis tick-values you can do as below. Please note: sometimes get_xticks() will have a ticks outside of the visible range, which you have to allow for when converting.

import matplotlib.pyplot as plt

fig, ax1 = plt.subplots()

ax1 = fig.add_subplot(111)

ax1.plot(range(5), range(5))

ax1.grid(True)

ax2 = ax1.twiny()
ax2.set_xticks( ax1.get_xticks() )
ax2.set_xbound(ax1.get_xbound())
ax2.set_xticklabels([x * 2 for x in ax1.get_xticks()])

title = ax1.set_title("Upper x-axis ticks are lower x-axis ticks doubled!")
title.set_y(1.1)
fig.subplots_adjust(top=0.85)

fig.savefig("1.png")

Gives:

What you want is to count all the lines in a relation (dataset in Pig Latin)

This is very easy following the next steps:

logs = LOAD 'log'; --relation called logs, using PigStorage with tab as field delimiter
logs_grouped = GROUP logs ALL;--gives a relation with one row with logs as a bag
number = FOREACH LOGS_GROUP GENERATE COUNT_STAR(logs);--show me the number

I have to say it is important Kevin's point as using COUNT instead of COUNT_STAR we would have only the number of lines which first field is not null.

Also I like Jerome's one line syntax it is more concise but in order to be didactic I prefer to divide it in two and add some comment.

In general I prefer:

numerito = FOREACH (GROUP CARGADOS3 ALL) GENERATE COUNT_STAR(CARGADOS3);

over

name = GROUP CARGADOS3 ALL
number = FOREACH name GENERATE COUNT_STAR(CARGADOS3);

I had this issue, but couldn't use an identity column (for various reasons). I settled on this:

DECLARE @id INT
SET @id = 0 
UPDATE table SET @id = id = @id + 1 

Borrowed from here.

In Xcode > 4.3:

You click on the scheme drop down bar -> edit scheme -> arguments tab and then add NSZombieEnabled in the Environment Variables column and YES in the value column.

Good Luck !!!

Here is how I get two arrays difference. Pure and clean.

It will return a object that contain [add list] and [remove list].

  function getDiff(past, now) {
        let ret = { add: [], remove: [] };
        for (var i = 0; i < now.length; i++) {
          if (past.indexOf(now[i]) < 0)
            ret['add'].push(now[i]);
        }
        for (var i = 0; i < past.length; i++) {
          if (now.indexOf(past[i]) < 0)
            ret['remove'].push(past[i]);
        }
        return ret;
      }

You can also do this with ArgueJS:

function (){
  arguments = __({nodebox: undefined, str: [String: "hai"]})

  // and now on, you can access your arguments by
  //   arguments.nodebox and arguments.str
}

Add this before calling curl_exec($curl_handle)

curl_setopt($curl_handle, CURLOPT_CUSTOMREQUEST, 'GET');

You could try using Linq to project the list:

var output = lst.Select(x => x % 2 == 0).ToList();

This will return a new list of bools such that {1, 2, 3, 4, 5} will map to {false, true, false, true, false}.

To give proper credit, I merged the concepts from Peter Mortensen (Jun 18 '14 at 21:02) and opello (Aug 25 '11 at 14:27).

You can write this much shorter, but this long version makes reading and understanding the code easy.

In Go 1.13 and later, you can use Value.IsZero method offered in reflect package.

if reflect.ValueOf(v).IsZero() {
    // v is zero, do something
}

Apart from basic types, it also works for Array, Chan, Func, Interface, Map, Ptr, Slice, UnsafePointer, and Struct. See this for reference.

Put double quotes around the path that has spaces like this:

REGSVR32 "E:\Documents and Settings\All Users\Application Data\xyz.dll"

You can also use DBMS_METADATA:

select dbms_metadata.get_ddl('FUNCTION', 'FGETALGOGROUPKEY', 'PADCAMPAIGN') 
from dual

I have used Arrays.toString(array_name).replace("[","").replace("]","").replace(", ",""); as I have seen it from some of the comments above, but also i added an additional space character after the comma (the part .replace(", ","")), because while I was printing out each value in a new line, there was still the space character shifting the words. It solved my problem.

There's no mystery here, the linker is telling you that you haven't defined the missing symbols, and you haven't.

Similarity::Similarity() or Similarity::~Similarity() are just missing and you have defined the others incorrectly,

void Similarity::readData(Scanner& inStream){
}

not

void readData(Scanner& inStream){
}

etc. etc.

The second one is a function called readData, only the first is the readData method of the Similarity class.

To be clear about this, in Similarity.h

void readData(Scanner& inStream);

but in Similarity.cpp

void Similarity::readData(Scanner& inStream){
}

Maybe the condition you are using is incorrect:

$str1 == "taste" && $str2 == "waste"

The program will enter into THEN part only when both of the stated conditions are true.

You can try with $str1 == "taste" || $str2 == "waste". This will execute the THEN part if anyone of the above conditions are true.

I had a similar problem and I searched for the solution for quite a while: It appears that the string parameter is case sensitive. So if your filename is abc.TXT but you search for abc.txt, eclipse will find it - the executable JAR file won't.

For those of you want to copy the cURL output in the clipboard instead of outputting to a file, you can use pbcopy by using the pipe | after the cURL command.

Example: curl https://www.google.com/robots.txt | pbcopy. This will copy all the content from the given URL to your clipboard.

In PyQt there are a lot of options for getting asynchronous behavior. For things that need event processing (ie. QtNetwork, etc) you should use the QThread example I provided in my other answer on this thread. But for the vast majority of your threading needs, I think this solution is far superior than the other methods.

The advantage of this is that the QThreadPool schedules your QRunnable instances as tasks. This is similar to the task pattern used in Intel's TBB. It's not quite as elegant as I like but it does pull off excellent asynchronous behavior.

This allows you to utilize most of the threading power of Qt in Python via QRunnable and still take advantage of signals and slots. I use this same code in several applications, some that make hundreds of asynchronous REST calls, some that open files or list directories, and the best part is using this method, Qt task balances the system resources for me.

    :param slot updatecb: the callback when data is receieved cb(uid, data)
    :param slot errorcb: the callback when there is an error cb(uid, errmsg)

    The uid option is useful when the calling code makes multiple async calls
    and the callbacks need some context about what was sent to the async method.
    For example, if you use this method to thread a long running database call
    and the user decides they want to cancel it and start a different one, the
    first one may complete before you have a chance to cancel the task.  In that
    case, the "readycb" will be called with the cancelled task's data.  The uid
    can be used to differentiate those two calls (ie. using the sql query).

I had same issue after installing nvm-windows on top of existing Node installation. Solution was just to follow the instructions:

You should also delete the existing npm install location (e.g. "C:\Users\AppData\Roaming\npm") so that the nvm install location will be correctly used instead.

Installation & Upgrades

Also note that if you want to apply an instance method to an array, you need to pass the function as:

call_user_func_array(array($instance, "MethodName"), $myArgs);

For the functional component, I would rather keep the props argument, so here is my solution:

interface Props {
  foo: string;
  bar?: number; 
}

// IMPORTANT!, defaultProps is of type {bar: number} rather than Partial<Props>!
const defaultProps = {
  bar: 1
}


// externalProps is of type Props
const FooComponent = exposedProps => {
  // props works like type Required<Props> now!
  const props = Object.assign(defaultProps, exposedProps);

  return ...
}

FooComponent.defaultProps = defaultProps;

int intVar = (int)ds.Tables[0].Rows[0][n];   // n = column index

Try this piece of code, rather than ObjectInputStream.

BufferedReader in = new BufferedReader (new InputStreamReader (socket.getInputStream ()));
while (true)
{
    String cominginText = "";
    try
    {
        cominginText = in.readLine ();
        System.out.println (cominginText);
    }
    catch (IOException e)
    {
        //error ("System: " + "Connection to server lost!");
        System.exit (1);
        break;
    }
}

The other answers don't work for me. I'm trying to get the command line working in Jenkins. All you need are the following command line arguments:

--non-interactive

--trust-server-cert

By default . (any character) does not match newline characters.

This means you can simply match zero or more of any character then append the end tag.

Find: <li><a href="#">.* Replace: $0</a>

I know it is an old question, but I was struggling finding the answer myself. Here is what I have come up with:

Python 3:

>>> num_dict = {'num': 0.123, 'num2': 0.127}
>>> "{0[num]:.2f}_{0[num2]:.2f}".format(num_dict) 
0.12_0.13

I had a similar problem.

I think the problem is that when you try to enclose two or more functions that deals with an array type of variable, php will return an error.

Let's say for example this one.

$data = array('key1' => 'Robert', 'key2' => 'Pedro', 'key3' => 'Jose');

// This function returns the last key of an array (in this case it's $data)
$lastKey = array_pop(array_keys($data));

// Output is "key3" which is the last array.
// But php will return “Strict Standards: Only variables should 
// be passed by reference” error.
// So, In order to solve this one... is that you try to cut 
// down the process one by one like this.

$data1  = array_keys($data);
$lastkey = array_pop($data1);

echo $lastkey;

There you go!

Here a full makefile example:

makefile

TARGET = prog

$(TARGET): main.o lib.a
    gcc $^ -o $@

main.o: main.c
    gcc -c $< -o $@

lib.a: lib1.o lib2.o
    ar rcs $@ $^

lib1.o: lib1.c lib1.h
    gcc -c -o $@ $<

lib2.o: lib2.c lib2.h
    gcc -c -o $@ $<

clean:
    rm -f *.o *.a $(TARGET)

explaining the makefile:

• target: prerequisites - the rule head
• $@ - means the target
• $^ - means all prerequisites
• $< - means just the first prerequisite
• ar - a Linux tool to create, modify, and extract from archives see the man pages for further information. The options in this case mean:
  • r - replace files existing inside the archive
  • c - create a archive if not already existent
  • s - create an object-file index into the archive

To conclude: The static library under Linux is nothing more than a archive of object files.

main.c using the lib

This small research proves and refines the answer by Magnus

The most platform-independent syntax is

(empty line)
[comment]: # (This actually is the most platform independent comment)

Both conditions are important:

1. Using # (and not <>)
2. With an empty line before the comment. Empty line after the comment has no impact on the result.

The strict Markdown specification CommonMark only works as intended with this syntax (and not with <> and/or an empty line)

To prove this we shall use the Babelmark2, written by John MacFarlane. This tool checks the rendering of particular source code in 28 Markdown implementations.

(+ — passed the test, - — didn't pass, ? — leaves some garbage which is not shown in rendered HTML).

• No empty lines, using <> 13+, 15-
• Empty line before the comment, using <> 20+, 8-
• Empty lines around the comment, using <> 20+, 8-
• No empty lines, using # 13+ 1? 14-
• Empty line before the comment, using # 23+ 1? 4-
• Empty lines around the comment, using # 23+ 1? 4-
• HTML comment with 3 hyphens 1+ 2? 25- from the chl's answer (note that this is different syntax)

This proves the statements above.

These implementations fail all 7 tests. There's no chance to use excluded-on-render comments with them.

Didn't find a complete code snippet of how to use $http.post method to send data to the server and why it was not working in this case.

Explanations of below code snippet...

1. I am using jQuery $.param function to serialize the JSON data to www post data

2. Setting the Content-Type in the config variable that will be passed along with the request of angularJS $http.post that instruct the server that we are sending data in www post format.

3. Notice the $htttp.post method, where I am sending 1st parameter as url, 2nd parameter as data (serialized) and 3rd parameter as config.

Remaining code is self understood.

$scope.SendData = function () {
           // use $.param jQuery function to serialize data from JSON 
            var data = $.param({
                fName: $scope.firstName,
                lName: $scope.lastName
            });

            var config = {
                headers : {
                    'Content-Type': 'application/x-www-form-urlencoded;charset=utf-8;'
                }
            }

            $http.post('/ServerRequest/PostDataResponse', data, config)
            .success(function (data, status, headers, config) {
                $scope.PostDataResponse = data;
            })
            .error(function (data, status, header, config) {
                $scope.ResponseDetails = "Data: " + data +
                    "<hr />status: " + status +
                    "<hr />headers: " + header +
                    "<hr />config: " + config;
            });
        };

Look at the code example of $http.post method here.

An old thread, but it may help someone like me. I resolved the issue by setting up SMTP server value to a legitimate value in PHP.ini

$(window).scroll(function() {    
    $('.logo_container, .slogan').css({
        "opacity" : ".1",
        "transition" : "opacity .8s ease-in-out"
    });
});

Check the fiddle: http://jsfiddle.net/2k3hfwo0/2/

You are creating a dictionary first, then passing that dictionary to an OrderedDict. For Python versions < 3.6 ^(*), by the time you do that, the ordering is no longer going to be correct. dict is inherently not ordered.

Pass in a sequence of tuples instead:

ship = [("NAME", "Albatross"),
        ("HP", 50),
        ("BLASTERS", 13),
        ("THRUSTERS", 18),
        ("PRICE", 250)]
ship = collections.OrderedDict(ship)

What you see when you print the OrderedDict is it's representation, and it is entirely correct. OrderedDict([('PRICE', 250), ('HP', 50), ('NAME', 'Albatross'), ('BLASTERS', 13), ('THRUSTERS', 18)]) just shows you, in a reproducable representation, what the contents are of the OrderedDict.

^(*): In the CPython 3.6 implementation, the dict type was updated to use a more memory efficient internal structure that has the happy side effect of preserving insertion order, and by extension the code shown in the question works without issues. As of Python 3.7, the Python language specification has been updated to require that all Python implementations must follow this behaviour. See this other answer of mine for details and also why you'd still may want to use an OrderedDict() for certain cases.

My version. Hope it helps.

In my module i am exporting classes this way:

export { SigninComponent } from './SigninComponent';
export { RegisterComponent } from './RegisterComponent';

This allow me to import multiple classes in file from same module:

import { SigninComponent, RegisterComponent} from "../auth.module";

PS: Of course @Fjut answer is correct, but same time it doesn't support multiple imports from same file. I would suggest to use both answers for your needs. But importing from module makes folder structure refactorings more easier.

I'm not sure why. But

oTable6.fnDraw();

Works for me. I put it in the next line.

When your view loads, so does its associated controller. Instead of using ng-init, simply call your init() method in your controller:

$scope.init = function () {
    if ($routeParams.Id) {
        //get an existing object
    } else {
        //create a new object
    }
    $scope.isSaving = false;
}
...
$scope.init();

Since your controller runs before ng-init, this also solves your second issue.

Fiddle

As John David Five mentioned, you might not want to attach this to $scope in order to make this method private.

var init = function () {
    // do something
}
...
init();

See jsFiddle

If you want to wait for certain data to be preset, either move that data request to a resolve or add a watcher to that collection or object and call your init method when your data meets your init criteria. I usually remove the watcher once my data requirements are met so the init function doesnt randomly re-run if the data your watching changes and meets your criteria to run your init method.

var init = function () {
    // do something
}
...
var unwatch = scope.$watch('myCollecitonOrObject', function(newVal, oldVal){
                    if( newVal && newVal.length > 0) {
                        unwatch();
                        init();
                    }
                });

For string comparisons in Perl, use eq or ne:

if ($str eq "")
{
  // ...
}

The == and != operators are numeric comparison operators. They will attempt to convert both operands to integers before comparing them.

See the perlop man page for more information.

Try details: use any option..

    MessageBox.Show("your message",
    "window title", 
    MessageBoxButtons.OK, 
    MessageBoxIcon.Warning // for Warning  
    //MessageBoxIcon.Error // for Error 
    //MessageBoxIcon.Information  // for Information
    //MessageBoxIcon.Question // for Question
   );

Use:

$.ajax({
    url: 'feed/4', type: 'POST', data: "_METHOD=PUT&accessToken=63ce0fde", success: function(data) {
        console.log(data);
    }
});

Always remember to use _METHOD=PUT.

In another way you can use window.location.href="your URL"

e.g.:

res.send('<script>window.location.href="your URL";</script>');

or:

return res.redirect("your url");

No, it's not possible, browsers have their own ways to implement tooltip. All you can do is to create some div that behaves like an HTML tooltip (mostly it's just 'show on hover') with Javascript, and then style it the way you want.

With this, you wouldn't have to worry about browser's zooming in or out, since the text inside the tooltip div is an actual HTML, it would scale accordingly.

See Jonathan's post for some good resource.

Wikipedia has the following information about USING:

The USING construct is more than mere syntactic sugar, however, since the result set differs from the result set of the version with the explicit predicate. Specifically, any columns mentioned in the USING list will appear only once, with an unqualified name, rather than once for each table in the join. In the case above, there will be a single DepartmentID column and no employee.DepartmentID or department.DepartmentID.

Tables that it was talking about:

The Postgres documentation also defines them pretty well:

The ON clause is the most general kind of join condition: it takes a Boolean value expression of the same kind as is used in a WHERE clause. A pair of rows from T1 and T2 match if the ON expression evaluates to true.

The USING clause is a shorthand that allows you to take advantage of the specific situation where both sides of the join use the same name for the joining column(s). It takes a comma-separated list of the shared column names and forms a join condition that includes an equality comparison for each one. For example, joining T1 and T2 with USING (a, b) produces the join condition ON T1.a = T2.a AND T1.b = T2.b.

Furthermore, the output of JOIN USING suppresses redundant columns: there is no need to print both of the matched columns, since they must have equal values. While JOIN ON produces all columns from T1 followed by all columns from T2, JOIN USING produces one output column for each of the listed column pairs (in the listed order), followed by any remaining columns from T1, followed by any remaining columns from T2.

There is equally formatDate

const format = 'dd/MM/yyyy';
const myDate = '2019-06-29';
const locale = 'en-US';
const formattedDate = formatDate(myDate, format, locale);

According to the API it takes as param either a date string, a Date object, or a timestamp.

Gotcha: Out of the box, only en-US is supported.

If you need to add another locale, you need to add it and register it in you app.module, for example for Spanish:

import { registerLocaleData } from '@angular/common';
import localeES from "@angular/common/locales/es";
registerLocaleData(localeES, "es");

Don't forget to add corresponding import:

import { formatDate } from "@angular/common";

I'll assume you are talking about Windows, right? I don't believe you can change the icon of a batch file directly. Icons are embedded in .EXE and .DLL files, or pointed to by .LNK files.

You could try to change the file association, but that approach may vary based on the version of Windows you are using. This is down with the registry in XP, but I'm not sure about Vista.

public DataSet GetDataSet(string ConnectionString, string SQL)
{
    SqlConnection conn = new SqlConnection(ConnectionString);
    SqlDataAdapter da = new SqlDataAdapter();
    SqlCommand cmd = conn.CreateCommand();
    cmd.CommandText = SQL;
    da.SelectCommand = cmd;
    DataSet ds = new DataSet();

    ///conn.Open();
    da.Fill(ds);
    ///conn.Close();

    return ds;
}

Check the answer from Marc from C#: Good/best implementation of Swap method.

public static void Swap<T>(IList<T> list, int indexA, int indexB)
{
    T tmp = list[indexA];
    list[indexA] = list[indexB];
    list[indexB] = tmp;
}

which can be linq-i-fied like

public static IList<T> Swap<T>(this IList<T> list, int indexA, int indexB)
{
    T tmp = list[indexA];
    list[indexA] = list[indexB];
    list[indexB] = tmp;
    return list;
}

var lst = new List<int>() { 8, 3, 2, 4 };
lst = lst.Swap(1, 2);

You can simply use value_counts on the series:

df['colour'].value_counts().plot(kind='bar')

If your keys are dynamic I would suggest deserializing directly into a DataTable:

    class SampleData
    {
        [JsonProperty(PropertyName = "items")]
        public System.Data.DataTable Items { get; set; }
    }

    public void DerializeTable()
    {
        const string json = @"{items:["
            + @"{""Name"":""AAA"",""Age"":""22"",""Job"":""PPP""},"
            + @"{""Name"":""BBB"",""Age"":""25"",""Job"":""QQQ""},"
            + @"{""Name"":""CCC"",""Age"":""38"",""Job"":""RRR""}]}";
        var sampleData = JsonConvert.DeserializeObject<SampleData>(json);
        var table = sampleData.Items;

        // write tab delimited table without knowing column names
        var line = string.Empty;
        foreach (DataColumn column in table.Columns)            
            line += column.ColumnName + "\t";                       
        Console.WriteLine(line);

        foreach (DataRow row in table.Rows)
        {
            line = string.Empty;
            foreach (DataColumn column in table.Columns)                
                line += row[column] + "\t";                                   
            Console.WriteLine(line);
        }

        // Name   Age   Job    
        // AAA    22    PPP    
        // BBB    25    QQQ    
        // CCC    38    RRR    
    }

You can determine the DataTable column names and types dynamically once deserialized.

This line:

private dynamic defaultReminder = 
                          reminder.TimeSpanText[TimeSpan.FromMinutes(15)];

You cannot use an instance variable to initialize another instance variable. Why? Because the compiler can rearrange these - there is no guarantee that reminder will be initialized before defaultReminder, so the above line might throw a NullReferenceException.

Instead, just use:

private dynamic defaultReminder = TimeSpan.FromMinutes(15);

Alternatively, set up the value in the constructor:

private dynamic defaultReminder;

public Reminders()
{
    defaultReminder = reminder.TimeSpanText[TimeSpan.FromMinutes(15)]; 
}

There are more details about this compiler error on MSDN - Compiler Error CS0236.

In my case i have included jdbc api dependencies in the project so the "Hello World" not printed. After removing the below dependency it works like a charm.

       <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-jdbc</artifactId>
        </dependency>

The problem obviously was (as you figured it out) that port 36250 wasn't open on the server side at the time you tried to connect (hence connection refused). I can see the server was supposed to open this socket after receiving SEND command on another connection, but it apparently was "not opening [it] up in sync with the client side".

Well, the main reason would be there was no synchronisation whatsoever. Calling:

cs.send("SEND " + FILE)
cs.close()

would just place the data into a OS buffer; close would probably flush the data and push into the network, but it would almost certainly return before the data would reach the server. Adding sleep after close might mitigate the problem, but this is not synchronisation.

The correct solution would be to make sure the server has opened the connection. This would require server sending you some message back (for example OK, or better PORT 36250 to indicate where to connect). This would make sure the server is already listening.

The other thing is you must check the return values of send to make sure how many bytes was taken from your buffer. Or use sendall.

(Sorry for disturbing with this late answer, but I found this to be a high traffic question and I really didn't like the sleep idea in the comments section.)

The so-called "Rosetta Flash" vulnerability is that allowing arbitrary yet identifier-like text at the beginning of a JSONP response is sufficient for it to be interpreted as a Flash file executing in that origin. See for more information: http://miki.it/blog/2014/7/8/abusing-jsonp-with-rosetta-flash/

JSONP responses from the proxy servlet now: * are prefixed with "/**/", which still allows them to execute as JSONP but removes requester control over the first bytes of the response. * have the response header Content-Disposition: attachment.

For Android Kotlin users:

"#FFF".longARGB()?.let{ Color.parceColor(it) }
"#FFFF".longARGB()?.let{ Color.parceColor(it) }

fun String?.longARGB(): String? {
    if (this == null || !startsWith("#")) return null
    
//    #RRGGBB or #AARRGGBB
    if (length == 7 || length == 9) return this

//    #RGB or #ARGB
    if (length in 4..5) {
        val rgb = "#${this[1]}${this[1]}${this[2]}${this[2]}${this[3]}${this[3]}"
        if (length == 5) {
            return "$rgb${this[4]}${this[4]}"
        }
        return rgb
    }

    return null
}

You can simply write :

class A(object):

    def __init__(self):
        print "Initialiser A was called"

class B(A):

    def __init__(self):
        A.__init__(self)
        # A.__init__(self,<parameters>) if you want to call with parameters
        print "Initialiser B was called"

class C(B):

    def __init__(self):
        # A.__init__(self) # if you want to call most super class...
        B.__init__(self)
        print "Initialiser C was called"

This is a little (very) late, but I'm posting this in case someone comes by this later.

The Support Library as of the Android L preview has a RecyclerView that does exactly what you want.

Right now, you can only get it through the L preview SDK and you need to set your minSdk to L. But you can copy all of the necessary files into your project and use them that way until L is officially out.

You can download the preview docs here.

Warning: The API for Recycler View may change and it may have bugs.

Updated

The source code for horizontal listview is:

LinearLayoutManager layoutManager
    = new LinearLayoutManager(this, LinearLayoutManager.HORIZONTAL, false);

RecyclerView myList = findViewById(R.id.my_recycler_view);
myList.setLayoutManager(layoutManager);

Let's see this in action:

var b = true;_x000D_
_x000D_
console.log(b); // true_x000D_
_x000D_
b = !b;_x000D_
console.log(b); // false_x000D_
_x000D_
b = !b;_x000D_
console.log(b); // true

Anyways, there is no shorter way than what you currently have.

In the top menu of MySQL Workbench click on database and then on forward engineer. In the options menu with which you will be presented, make sure to have "generate insert statements for tables" set.

The problem with taking IEnumerable as a parameter is that it tells callers "I wish to enumerate this". It doesn't tell them how many times you wish to enumerate.

I can change the objects parameter to be List and then avoid the possible multiple enumeration but then I don't get the highest object that I can handle.

The goal of taking the highest object is noble, but it leaves room for too many assumptions. Do you really want someone to pass a LINQ to SQL query to this method, only for you to enumerate it twice (getting potentially different results each time?)

The semantic missing here is that a caller, who perhaps doesn't take time to read the details of the method, may assume you only iterate once - so they pass you an expensive object. Your method signature doesn't indicate either way.

By changing the method signature to IList/ICollection, you will at least make it clearer to the caller what your expectations are, and they can avoid costly mistakes.

Otherwise, most developers looking at the method might assume you only iterate once. If taking an IEnumerable is so important, you should consider doing the .ToList() at the start of the method.

It's a shame .NET doesn't have an interface that is IEnumerable + Count + Indexer, without Add/Remove etc. methods, which is what I suspect would solve this problem.

You can do something like

    SELECT *
      FROM (SELECT Fname FROM MyTbl ORDER BY Fname )
 WHERE rownum = 1;

You could also use the analytic functions RANK and/or DENSE_RANK, but ROWNUM is probably the easiest.

The default value is indeed false.

However you can't use a local variable is it's not been assigned first.

You can use the default keyword to verify:

bool foo = default(bool);
if (!foo) { Console.WriteLine("Default is false"); }

To remove specific key and element from hashmap use

hashmap.remove(key)

full source code is like

import java.util.HashMap;
public class RemoveMapping {
     public static void main(String a[]){
        HashMap hashMap = new HashMap();
        hashMap.put(1, "One");
        hashMap.put(2, "Two");
        hashMap.put(3, "Three");
        System.out.println("Original HashMap : "+hashMap);
        hashMap.remove(3);   
        System.out.println("Changed HashMap : "+hashMap);        
    }
}

If you use RequestDispatcher.forward() to route the request from controller to the view, then request URI is exposed as a request attribute named javax.servlet.forward.request_uri. So, you can use

request.getAttribute("javax.servlet.forward.request_uri")

or

${requestScope['javax.servlet.forward.request_uri']}

function setGetParameter(paramName, paramValue)
{
    var url = window.location.href;
    var hash = location.hash;
    url = url.replace(hash, '');
    if (url.indexOf(paramName + "=") >= 0)
    {
        var prefix = url.substring(0, url.indexOf(paramName + "=")); 
        var suffix = url.substring(url.indexOf(paramName + "="));
        suffix = suffix.substring(suffix.indexOf("=") + 1);
        suffix = (suffix.indexOf("&") >= 0) ? suffix.substring(suffix.indexOf("&")) : "";
        url = prefix + paramName + "=" + paramValue + suffix;
    }
    else
    {
    if (url.indexOf("?") < 0)
        url += "?" + paramName + "=" + paramValue;
    else
        url += "&" + paramName + "=" + paramValue;
    }
    window.location.href = url + hash;
}

Call the function above in your onclick event.

In R the equivalent function is seq and you can use it with the option by:

seq(from = 5, to = 100, by = 5)
# [1]   5  10  15  20  25  30  35  40  45  50  55  60  65  70  75  80  85  90  95 100

In addition to by you can also have other options such as length.out and along.with.

length.out: If you want to get a total of 10 numbers between 0 and 1, for example:

seq(0, 1, length.out = 10)
# gives 10 equally spaced numbers from 0 to 1

along.with: It takes the length of the vector you supply as input and provides a vector from 1:length(input).

seq(along.with=c(10,20,30))
# [1] 1 2 3

Although, instead of using the along.with option, it is recommended to use seq_along in this case. From the documentation for ?seq

seq is generic, and only the default method is described here. Note that it dispatches on the class of the first argument irrespective of argument names. This can have unintended consequences if it is called with just one argument intending this to be taken as along.with: it is much better to use seq_along in that case.

seq_along: Instead of seq(along.with(.))

seq_along(c(10,20,30))
# [1] 1 2 3

Hope this helps.

If you give your table a unique id, its easier:

<div id="ctl00_ContentPlaceHolder1_Jobs_dlItems_ctl01_a"
    onmouseup="checkMultipleSelection(this,event);">
       <table id="ctl00_ContentPlaceHolder1_Jobs_dlItems_ctl01_a_table" 
              cellpadding="0" cellspacing="0" border="0" width="100%">
           <tr>
              <td style="width:50px; text-align:left;">09:15 AM</td>
              <td style="width:50px; text-align:left;">Item001</td>
              <td style="width:50px; text-align:left;">10</td>
              <td style="width:50px; text-align:left;">Address1</td>
              <td style="width:50px; text-align:left;">46545465</td>
              <td style="width:50px; text-align:left;">ref1</td>
           </tr>
       </table>
</div>


var multiselect = 
    document.getElementById(
               'ctl00_ContentPlaceHolder1_Jobs_dlItems_ctl01_a_table'
            ).rows[0].cells,
    timeXaddr = [multiselect[0].innerHTML, multiselect[2].innerHTML];

//=> timeXaddr now an array containing ['09:15 AM', 'Address1'];

The following simple steps help me:

First, initialize the repository to work with Git, so that any file changes are tracked:

git init

Then, check that the remote repository that you want to associate with the alias origin exists, if not create it in git first.

$ git ls-remote https://github.com/repo-owner/repo-name.git/

If it exists, associate it with the remote "origin":

git remote add origin https://github.com:/repo-owner/repo-name.git

and check to which URL, the remote "origin" belongs to by using git remote -v:

$ git remote -v
origin  https://github.com:/repo-owner/repo-name.git (fetch)
origin  https://github.com:/repo-owner/repo-name.git (push)

Next, verify if your origin is properly aliased as follows:

$ cat ./.git/config
:
[remote "origin"]
        url = https://github.com:/repo-owner/repo-name.git
        fetch = +refs/heads/*:refs/remotes/origin/*
:

You need to see this section [remote "origin"]. You can consider to use GitHub Desktop available for both Windows and MacOS, which help me to automatically populate the missing section/s in ~./git/config file OR you can manually add it, not great, but hey it works!

[Optional]
You might also want to change the origin alias to make it more intuitive, especially if you are working with multiple origin:

git remote rename origin mynewalias

or even remove it:

git remote rm origin

Finally, on your first push, if you want master in that repository to be your default upstream. you may want to add the -u parameter

git add .
git commit -m 'First commit'
git push -u origin master

-Contains is actually a collection operator. It is true if the collection contains the object. It is not limited to strings.

-match and -imatch are regular expression string matchers, and set automatic variables to use with captures.

-like, -ilike are SQL-like matchers.
