Only providing .ttf file for webfont won't be good enough for cross-browser support. The best possible combination at present is using the combination as :

@font-face {
  font-family: 'MyWebFont';
  src: url('webfont.eot'); /* IE9 Compat Modes */
  src: url('webfont.eot?#iefix') format('embedded-opentype'), /* IE6-IE8 */
       url('webfont.woff') format('woff'), /* Modern Browsers */
       url('webfont.ttf')  format('truetype'), /* Safari, Android, iOS */
       url('webfont.svg#svgFontName') format('svg'); /* Legacy iOS */
}

This code assumes you have .eot , .woff , .ttf and svg format for you webfont. To automate all this process , you can use : Transfonter.org.

Also , modern browsers are shifting towards .woff font , so you can probably do this too : :

@font-face {
  font-family: 'MyWebFont';
  src: url('myfont.woff') format('woff'), /* Chrome 6+, Firefox 3.6+, IE 9+, Safari 5.1+ */
   url('myfont.ttf') format('truetype'); /* Chrome 4+, Firefox 3.5, Opera 10+, Safari 3—5 */
}

My problem was that it didn't work with a passphrase on my private key.

Hope that helps someone.

If you are using iscroll.js on webkit browser or mobile browser, you could try:

$('#pageWrapper>div:last-child').css('top', "0px");

Make sure you're in the right directory when you start the server

sites>yoursite> rails s

If you must, this is how you can do it in a for loop:

mylist = ['first', 'second', 'other']
endstring = ''
for s in mylist:
  endstring += s

but you should consider using join():

''.join(mylist)

If jQuery is okay, you can use find(). It's basically equivalent to the way you are doing it right now.

$('#note').find('#textid');

You can also use jQuery selectors to basically achieve the same thing:

$('#note #textid');

Using these methods to get something that already has an ID is kind of strange, but I'm supplying these assuming it's not really how you plan on using it.

On a side note, you should know ID's should be unique in your webpage. If you plan on having multiple elements with the same "ID" consider using a specific class name.

Update 2020.03.10

It's a breeze to use native JS for this:

document.querySelector('#note #textid');

If you want to first find #note then #textid you have to check the first querySelector result. If it fails to match, chaining is no longer possible :(

var parent = document.querySelector('#note');
var child = parent ? parent.querySelector('#textid') : null;

You first have to 'dot' source the script, so for you :

. .\Get-NetworkStatistics.ps1

The first 'dot' asks PowerShell to load the script file into your PowerShell environment, not to start it. You should also use set-ExecutionPolicy Unrestricted or set-ExecutionPolicy AllSigned see(the Execution Policy instructions).

You may connect to Oracle database using sqlplus:

sqlplus "/as sysdba"

Then create new users and assign privileges.

grant all privileges to dac;

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

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

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

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

You can achieve your desired through easily by CSS :-

HTML

<input type="submit" name="submit" value="Submit Application" id="submit" />

CSS

#submit {
    background-color: #ccc;
    -moz-border-radius: 5px;
    -webkit-border-radius: 5px;
    border-radius:6px;
    color: #fff;
    font-family: 'Oswald';
    font-size: 20px;
    text-decoration: none;
    cursor: pointer;
    border:none;
}



#submit:hover {
    border: none;
    background:red;
    box-shadow: 0px 0px 1px #777;
}

DEMO

1. Go to File -> Source Control -> Advanced -> Change Source Control (if change source control doesn't appear, click on solution in the solution explorer then try again)
2. Unbind solution and all projects

Now right click on solution and you will see "Add Project To Source Control". if you want to add project to source control again you might be get some errors that ask you to change the solution folder on TFS. it happens because your solution has some mapping in a workspace yet. remove mapping or delete workspace. now your solution is completely unbind and unmapped from TFS or workspaces.

you can update all of the dependencies to their latest version by npm update

Use Connection.isClosed() function.

The JavaDoc states:

Retrieves whether this Connection object has been closed. A connection is closed if the method close has been called on it or if certain fatal errors have occurred. This method is guaranteed to return true only when it is called after the method Connection.close has been called.

Example 2012:

library("xlsx")
FirstTable <- read.xlsx("MyExcelFile.xlsx", 1 , stringsAsFactors=F)
SecondTable <- read.xlsx("MyExcelFile.xlsx", 2 , stringsAsFactors=F)

• I would try 'xlsx' package for it is easy to handle and seems mature enough
• worked fine for me and did not need any additionals like Perl or whatever

Example 2015:

library("readxl")
FirstTable  <- read_excel("MyExcelFile.xlsx", 1)
SecondTable <- read_excel("MyExcelFile.xlsx", 2)

• nowadays I use readxl and have made good experience with it.
• no extra stuff needed
• good performance

 NSMutableDictionary *contentDictionary = [[NSMutableDictionary alloc]init];
[contentDictionary setValue:@"name" forKey:@"email"];
[contentDictionary setValue:@"name" forKey:@"username"];
[contentDictionary setValue:@"name" forKey:@"password"];
[contentDictionary setValue:@"name" forKey:@"firstName"];
[contentDictionary setValue:@"name" forKey:@"lastName"];

NSData *data = [NSJSONSerialization dataWithJSONObject:contentDictionary options:NSJSONWritingPrettyPrinted error:nil];
NSString *jsonStr = [[NSString alloc] initWithData:data
                                          encoding:NSUTF8StringEncoding];
NSLog(@"%@",jsonStr);

NSString *urlString = [NSString stringWithFormat:@"http://testgcride.com:8081/v1/users"];
NSURL *url = [NSURL URLWithString:urlString];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setHTTPMethod:@"POST"];
   [request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];


[request setHTTPBody:[jsonStr dataUsingEncoding:NSUTF8StringEncoding]];

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager.requestSerializer setAuthorizationHeaderFieldWithUsername:@"moinsam" password:@"cheese"];
manager.requestSerializer = [AFJSONRequestSerializer serializer];

AFHTTPRequestOperation *operation = [manager HTTPRequestOperationWithRequest:request success:<block> failure:<block>];

for linux (bash) following code works for me:

System.out.print("\033[31mERROR  \033[0m");

the \033[31m will switch the color to red and \033[0m will switch it back to normal.

This is now possible through the WhatsApp Business API. Only businesses may apply to use it. This is the only way to directly send messages to phone numbers, without any human interaction.

Sending normal messages is free. It looks like you need to host a MySQL database and the WhatsApp Business Client on your server.

It means that you compiled your classes under a specific JDK, but then try to run them under older version of JDK.

It depends on how you tested it, and possibly on differences in the TCP stack implementation of the personal computer and the server.

For example, if your sendall always completes immediately (or very quickly) on the personal computer, the connection may simply never have broken during sending. This is very likely if your browser is running on the same machine (since there is no real network latency).

In general, you just need to handle the case where a client disconnects before you're finished, by handling the exception.

Remember that TCP communications are asynchronous, but this is much more obvious on physically remote connections than on local ones, so conditions like this can be hard to reproduce on a local workstation. Specifically, loopback connections on a single machine are often almost synchronous.

Lee's approach can be simplified further

public static void InvokeIfRequired(this Control control, MethodInvoker action)
{
    // See Update 2 for edits Mike de Klerk suggests to insert here.

    if (control.InvokeRequired) {
        control.Invoke(action);
    } else {
        action();
    }
}

And can be called like this

richEditControl1.InvokeIfRequired(() =>
{
    // Do anything you want with the control here
    richEditControl1.RtfText = value;
    RtfHelpers.AddMissingStyles(richEditControl1);
});

There is no need to pass the control as parameter to the delegate. C# automatically creates a closure.

UPDATE:

According to several other posters Control can be generalized as ISynchronizeInvoke:

public static void InvokeIfRequired(this ISynchronizeInvoke obj,
                                         MethodInvoker action)
{
    if (obj.InvokeRequired) {
        var args = new object[0];
        obj.Invoke(action, args);
    } else {
        action();
    }
}

DonBoitnott pointed out that unlike Control the ISynchronizeInvoke interface requires an object array for the Invoke method as parameter list for the action.

UPDATE 2

Edits suggested by Mike de Klerk (see comment in 1st code snippet for insert point):

// When the form, thus the control, isn't visible yet, InvokeRequired  returns false,
// resulting still in a cross-thread exception.
while (!control.Visible)
{
    System.Threading.Thread.Sleep(50);
}

See ToolmakerSteve's comment below for concerns about this suggestion.

I'd love to post this as a comment to Tendayi Mawushe's answer, but I'm afraid there is not enough space ;)

This is the relevant part from the Apache Commons UrlValidator source:

/**
 * This expression derived/taken from the BNF for URI (RFC2396).
 */
private static final String URL_PATTERN =
        "/^(([^:/?#]+):)?(//([^/?#]*))?([^?#]*)(\\?([^#]*))?(#(.*))?/";
//         12            3  4          5       6   7        8 9

/**
 * Schema/Protocol (ie. http:, ftp:, file:, etc).
 */
private static final int PARSE_URL_SCHEME = 2;

/**
 * Includes hostname/ip and port number.
 */
private static final int PARSE_URL_AUTHORITY = 4;

private static final int PARSE_URL_PATH = 5;

private static final int PARSE_URL_QUERY = 7;

private static final int PARSE_URL_FRAGMENT = 9;

You can easily build your own validator from there.

Try this

{{ Request::segment(1) }}

Concerning the answer by BoltClock and John, I personally had issues with the initial keyword when using IE11. It works fine in Chrome, but in IE it seems to have no effect.

According to this answer IE does not support the initial keyword: Div display:initial not working as intended in ie10 and chrome 29

I tried setting it blank instead as suggested here: how to revert back to normal after display:none for table row

This worked and was good enough for my scenario. Of course to set the real initial value the above answer is the only good one I could find.

Not really - but I don't see how git fetch would hurt as it won't change any of your local branches.

To read one byte:

file.read(1)

8 bits is one byte.

You say you've had problems with Navicat. For the record, I use Navicat and I haven't experienced the issue you describe. You might want to dig around, see if there's a reason for your problem and/or a solution, because given the question asked, my first recommendation would have been Navicat.

But if you want alternative suggestions, here are a few that I know of and have used:

MySQL has its own tool which you can download for free, called MySQL Workbench. Download it from here: http://wb.mysql.com/. My experience is that it's powerful, but I didn't really like the UI. But that's just my personal taste.

Another free program you might want to try is HeidiSQL. It's more similar to Navicat than MySQL Workbench. A colleague of mine loves it.

(interesting to note, by the way, that MariaDB (the forked version of MySQL) is currently shipped with HeidiSQL as its GUI tool)

Finally, if you're running a web server on your machine, there's always the option of a browser-based tool like PHPMyAdmin. It's actually a surprisingly powerful piece of software.

    int[][] matrix = {
        {1,2,3},
        {4,5,6},
        {7,8,9}
    };
    //use foreach loop as below to avoid IndexOutOfBoundException
    //need to check matrix != null if implements as a method
    //for each row in the matrix
    for (int[] row : matrix) {
        //for each number in the row
        for (int j : row) {
            System.out.print(j + " ");
        }
        System.out.println("");
    }

I've had some luck with the Java Service Wrapper

<View style={{...StyleSheet.absoluteFillObject, justifyContent: 'center', alignItems: 'center'}}>
  <Text>CENTERD TEXT</Text>
</View>

And add this

import {StyleSheet} from 'react-native';

In my programs, by convention, this is what the pre-existing $REPLY variable is for, which read uses for that exact purpose.

function getSomeString {
  REPLY="tadaa"
}

getSomeString
echo $REPLY

This echoes

tadaa

But to avoid conflicts, any other global variable will do.

declare result

function getSomeString {
  result="tadaa"
}

getSomeString
echo $result

If that isn’t enough, I recommend Markarian451’s solution.

Inside of your <head></head> tags add...

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script>
$(document).ready(function(){
    $('input[type=radio]').change(function() {

    $('input[type=radio]').each(function(index) {
        $(this).closest('tr').removeClass('selected');
    });

        $(this).closest('tr').addClass('selected');
    });
});
</script>

EDIT: The placement inside of <head></head> is not the only option...this could just as easily be placed RIGHT before the closing </body> tag. I generally try and place my JavaScript inside of head for placement reasons, but it can in some cases slow down page rendering so some will recommend the latter approach (before closing body).

I have spent the last few days trying to figure this out myself. Using the old json dataType gives you cross origin problems, while setting the dataType to jsonp makes the data "unreadable" as explained above. So there are apparently two ways out, the first hasn't worked for me but seems like a potential solution and that I might be doing something wrong. This is explained here [ https://learn.jquery.com/ajax/working-with-jsonp/ ].

The one that worked for me is as follows: 1- download the ajax cross origin plug in [ http://www.ajax-cross-origin.com/ ]. 2- add a script link to it just below the normal jQuery link. 3- add the line "crossOrigin: true," to your ajax function.

Good to go! here is my working code for this:

  $.ajax({_x000D_
      crossOrigin: true,_x000D_
      url : "https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=-33.86,151.195&radius=5000&type=ATM&keyword=ATM&key=MyKey",_x000D_
      type : "GET",_x000D_
      success:function(data){_x000D_
         console.log(data);_x000D_
      }_x000D_
    })

You mean like this?

class MyResourcePolicy : IResourcePolicy {
    private string version;

    public string Version {
        get {
            return this.version;
        }
        set {
            this.version = value;
        }
    }
}

you try this:

<input type="submit" style="font-face: 'Comic Sans MS'; font-size: larger; color: teal; background-color: #FFFFC0; border: 3pt ridge lightgrey" value=" Send Me! ">

That ~~ is a double NOT bitwise operator.

It is used as a faster substitute for Math.floor() for positive numbers. It does not return the same result as Math.floor() for negative numbers, as it just chops off the part after the decimal (see other answers for examples of this).

This solution also gives the direction to search in the given board

Algo:

1. Uses trie to save all the word in the english to fasten the search
2. The uses DFS to search the words in Boggle

Output:

Just google for "Free WebService" or "Open WebService" and you'll find tons of open SOAP endpoints.

Remember, you can get a WSDL from any ASMX endpoint by adding ?WSDL to the url.

SELECT varchar_col

• For XHTML, <input type="text" disabled="disabled" /> is the valid markup.
• For HTML5, <input type="text" disabled /> is valid and used by W3C on their samples.
• In fact, both ways works on all major browsers.

Here is a shorthand that webpack will use so you don't have to use require.context.

HTML:

<div class="col-lg-2" v-for="pic in pics">
    <img :src="getImgUrl(pic)" v-bind:alt="pic">
</div>

Vue Method:

getImgUrl(pic) {
    return require('../assets/'+pic)
}

And I find that the first 2 paragraphs in here explain why this works? well.

Please note that it's a good idea to put your pet pictures inside a subdirectory, instead of lobbing it in with all your other image assets. Like so: ./assets/pets/

In one line we can set image with this code

[buttonName setBackgroundImage:[UIImage imageNamed:@"imageName"] forState:UIControlStateNormal];

Set the default value for the active argument in the route.

With Eclipse and Windows:

you have to copy 2 files - xxxPROJECTxxx.properties - log4j.properties here : C:\Eclipse\CONTENER\TOMCAT\apache-tomcat-7\lib

Whenever user communicate with bot it send information like below:

$response = {
        "update_id":640046715,
        "message":{
            "message_id":1665,
            "from":{"id":108177xxxx,"is_bot":false,"first_name":"Suresh","last_name":"Kamrushi","language_code":"en"},
            "chat":{"id":108xxxxxx,"first_name":"Suresh","last_name":"Kamrushi","type":"private"},
            "date":1604381276,
            "text":"1"            
            }        
        }

So you can access chat it like:
$update["message"]["chat"]["id"]

Assuming you are using PHP.

Usually when a method accepts a file, there's another method nearby that accepts a stream. If this isn't the case, the API is badly coded. Otherwise, you can use temporary files, where permission is usually granted in many cases. If it's applet, you can request write permission.

An example:

try {
    // Create temp file.
    File temp = File.createTempFile("pattern", ".suffix");

    // Delete temp file when program exits.
    temp.deleteOnExit();

    // Write to temp file
    BufferedWriter out = new BufferedWriter(new FileWriter(temp));
    out.write("aString");
    out.close();
} catch (IOException e) {
}

What I did is first check what are the running processes by

SELECT * FROM pg_stat_activity WHERE state = 'active';

Find the process you want to kill, then type:

SELECT pg_cancel_backend(<pid of the process>)

This basically "starts" a request to terminate gracefully, which may be satisfied after some time, though the query comes back immediately.

If the process cannot be killed, try:

SELECT pg_terminate_backend(<pid of the process>)

The reason for the error is that the nextInt only pulls the integer, not the newline. If you add a in.nextLine() before your for loop, it will eat the empty new line and allow you to enter 3 names.

int nnames;
String names[];

System.out.print("How many names are you going to save: ");
Scanner in = new Scanner(System.in);
nnames = in.nextInt();

names = new String[nnames];
in.nextLine();
for (int i = 0; i < names.length; i++){
        System.out.print("Type a name: ");
        names[i] = in.nextLine();
}

or just read the line and parse the value as an Integer.

int nnames;
String names[];

System.out.print("How many names are you going to save: ");
Scanner in = new Scanner(System.in);
nnames = Integer.parseInt(in.nextLine().trim());

names = new String[nnames];
for (int i = 0; i < names.length; i++){
        System.out.print("Type a name: ");
        names[i] = in.nextLine();
}

Try Wrap widget to wrap text as text grows:

Example:

Wrap(
  direction: Axis.vertical, //Vertical || Horizontal
  children: <Widget>[
    Text(
      'Your Text',
      style: TextStyle(fontSize: 30),
    ),
    Text(
      'Your Text',
      style: TextStyle(fontSize: 30),
    ),
  ],
),

To create these constraints through the GUI you need the "indexes and keys" dialogue not the check constraints one.

But in your case you just need to run the piece of code you already have. It doesn't need to be entered into the expression dialogue at all.

The # is an id selector. It matches only elements with a matching id. Next style rule will match the element that has an id attribute with a value of "green":

#green {color: green}

The docs mention train_test_split is just a convenience function on top of shuffle split.

I just rearranged some of their code to make my own example. Note the actual solution is the middle block of code. The rest is imports, and setup for a runnable example.

from sklearn.model_selection import ShuffleSplit
from sklearn.utils import safe_indexing, indexable
from itertools import chain
import numpy as np
X = np.reshape(np.random.randn(20),(10,2)) # 10 training examples
y = np.random.randint(2, size=10) # 10 labels
seed = 1

cv = ShuffleSplit(random_state=seed, test_size=0.25)
arrays = indexable(X, y)
train, test = next(cv.split(X=X))
iterator = list(chain.from_iterable((
    safe_indexing(a, train),
    safe_indexing(a, test),
    train,
    test
    ) for a in arrays)
)
X_train, X_test, train_is, test_is, y_train, y_test, _, _  = iterator

print(X)
print(train_is)
print(X_train)

Now I have the actual indexes: train_is, test_is

Use:

System.Configuration.ConfigurationSettings.AppSettings["MyKey"];

AppSettings has been deprecated and is now considered obsolete (link).

In addition, the appSettings section of the app.config has been replaced by the applicationSettings section.

As someone else mentioned, you should be using System.Configuration.ConfigurationManager (link) which is new for .NET 2.0.

You will need to create a public/private key as the Jenkins user on your Jenkins server, then copy the public key to the user you want to do the deployment with on your target server.

Step 1, generate public and private key on build server as user jenkins

build1:~ jenkins$ whoami
jenkins
build1:~ jenkins$ ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/var/lib/jenkins/.ssh/id_rsa): 
Created directory '/var/lib/jenkins/.ssh'.
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /var/lib/jenkins/.ssh/id_rsa.
Your public key has been saved in /var/lib/jenkins/.ssh/id_rsa.pub.
The key fingerprint is:
[...] 
The key's randomart image is:
[...]
build1:~ jenkins$ ls -l .ssh
total 2
-rw-------  1 jenkins  jenkins  1679 Feb 28 11:55 id_rsa
-rw-r--r--  1 jenkins  jenkins   411 Feb 28 11:55 id_rsa.pub 
build1:~ jenkins$ cat .ssh/id_rsa.pub
ssh-rsa AAAlskdjfalskdfjaslkdjf... [email protected]

Step 2, paste the pub file contents onto the target server.

target:~ bob$ cd .ssh
target:~ bob$ vi authorized_keys (paste in the stuff which was output above.)

Make sure your .ssh dir has permissoins 700 and your authorized_keys file has permissions 644

Step 3, configure Jenkins

1. In the jenkins web control panel, nagivate to "Manage Jenkins" -> "Configure System" -> "Publish over SSH"
2. Either enter the path of the file e.g. "var/lib/jenkins/.ssh/id_rsa", or paste in the same content as on the target server.
3. Enter your passphrase, server and user details, and you are good to go!

If you simply need a list, you could use:

List<Answer> answers = Arrays.asList(answer1, answer2, answer3);

If you specifically require an ArrayList, you could use:

ArrayList<Answer> answers = new ArrayList(Arrays.asList(answer1, answer2, answer3));

You can also use regex.

let trimmedString = myString.stringByReplacingOccurrencesOfString("\\s", withString: "", options: NSStringCompareOptions.RegularExpressionSearch, range: nil)

This will delete all rows in Table1 that match the criteria:

DELETE Table1 
FROM Table2 
WHERE Table1.JoinColumn = Table2.JoinColumn And Table1.SomeStuff = 'SomeStuff'

Extension IDs can be found in:

chrome://extensions (Chrome_Hotdog >> More_tools >> Extensions) Developer mode.

For Linux: $HOME/.config/google-chrome/Default/Preferences (json file) under ["extensions"].

Since you mention cls, it sounds like you are referring to windows. If so, then this KB item has the code that will do it. I just tried it, and it worked when I called it with the following code:

cls( GetStdHandle( STD_OUTPUT_HANDLE ));

You need to get the PropertyInfo associated with the property (e.g. via typeof(Class1).GetProperty("Name")) and then call GetCustomAttributes.

It's a bit messy due to returning multiple values - you may well want to write a helper method to do this if you need it from a few places. (There may already be a helper method in the framework somewhere, but if there is I'm unaware of it.)

EDIT: As leppie pointed out, there is such a method: Attribute.GetCustomAttribute(MemberInfo, Type)

We could also use an initializer_list if all arguments are const and of the same type

For POI 3.17 this worked for me

switch (cellh.getCellTypeEnum()) {
    case FORMULA: 
        if (cellh.getCellFormula().indexOf("LINEST") >= 0) {
            value = Double.toString(cellh.getNumericCellValue());
        } else {
            value = XLS_getDataFromCellValue(evaluator.evaluate(cellh));
        }
        break;
    case NUMERIC:
        value = Double.toString(cellh.getNumericCellValue());
        break;
    case STRING:
        value = cellh.getStringCellValue();
        break;
    case BOOLEAN:
        if(cellh.getBooleanCellValue()){
            value = "true";
        } else {
            value = "false";
        }
        break;
    default:
        value = "";
        break;
}

You created the UIButton is added the ViewController, The following instance method to change UIFont, tintColor and TextColor of the UIButton

Objective-C

 buttonName.titleLabel.font = [UIFont fontWithName:@"LuzSans-Book" size:15];
 buttonName.tintColor = [UIColor purpleColor];
 [buttonName setTitleColor:[UIColor purpleColor] forState:UIControlStateNormal];

Swift

buttonName.titleLabel.font = UIFont(name: "LuzSans-Book", size: 15)
buttonName.tintColor = UIColor.purpleColor()
buttonName.setTitleColor(UIColor.purpleColor(), forState: .Normal)

Swift3

buttonName.titleLabel?.font = UIFont(name: "LuzSans-Book", size: 15)
buttonName.tintColor = UIColor.purple
buttonName.setTitleColor(UIColor.purple, for: .normal)

melt() from the reshape2 package gets you close ...

library(reshape2)
(res <- melt(as.data.frame(mat), id="time"))
#   time variable value
# 1  0.0      C_0   0.1
# 2  0.5      C_0   0.2
# 3  1.0      C_0   0.3
# 4  0.0      C_1   0.3
# 5  0.5      C_1   0.4
# 6  1.0      C_1   0.5

... although you may want to post-process its results to get your preferred column names and ordering.

setNames(res[c("variable", "time", "value")], c("name", "time", "val"))
#   name time val
# 1  C_0  0.0 0.1
# 2  C_0  0.5 0.2
# 3  C_0  1.0 0.3
# 4  C_1  0.0 0.3
# 5  C_1  0.5 0.4
# 6  C_1  1.0 0.5

git checkout -b NEW_BRANCH_NAME COMMIT_ID

This will create a new branch called 'NEW_BRANCH_NAME' and check it out.

("check out" means "to switch to the branch")

git branch NEW_BRANCH_NAME COMMIT_ID

This just creates the new branch without checking it out.

in the comments many people seem to prefer doing this in two steps. here's how to do so in two steps:

git checkout COMMIT_ID
# you are now in the "detached head" state
git checkout -b NEW_BRANCH_NAME

open http://localhost:8080/ in browser, if you get tomcat home page. it means tomcat is running

CURRENT_DATE and CURRENT_TIMESTAMP return the current date and time in the session time zone.

SYSDATE and SYSTIMESTAMP return the system date and time - that is, of the system on which the database resides.

If your client session isn't in the same timezone as the server the database is on (or says it isn't anyway, via your NLS settings), mixing the SYS* and CURRENT_* functions will return different values. They are all correct, they just represent different things. It looks like your server is (or thinks it is) in a +4:00 timezone, while your client session is in a +4:30 timezone.

You might also see small differences in the time if the clocks aren't synchronised, which doesn't seem to be an issue here.

SOLUTION After all this time, I managed to resolve the problem.

In Module: UserForms(Name).Userform_Initialize

This method works best to dynamically init the current UserForm

I think this will meet your requirements:

I tried different solutions but what finally worked for me was plt.show(block=True). You need to add this command after the myDataFrame.plot() command for this to take effect. If you have multiple plot just add the command at the end of your code. It will allow you to see every data you are plotting.

When it can be the same header for all requests or you dispose the client after each request you can use the DefaultRequestHeaders.Add option:

client.DefaultRequestHeaders.Add("apikey","xxxxxxxxx");      

connect your device to system and set you device debug mode on when you run your application Android Virtual Device AVD will select device there you will see your connected device select your mobile device and thats all refer this link to set your device debugging mode on

Use char instead of byte:

System.out.println("string " + (char)0x63);

Or if you want to be a Unicode puritan, you use codepoints:

System.out.println("string " + new String(new int[]{ 0x63 }, 0, 1));

And if you like the old skool US-ASCII "every byte is a character" idea:

System.out.println("string " + new String(new byte[]{ (byte)0x63 },
                                          StandardCharsets.US_ASCII));

Avoid using the String(byte[]) constructor recommended in other answers; it relies on the default charset. Circumstances could arise where 0x63 actually isn't the character c.

Go to

Tools > Compatibility View settings > Uncheck the option "Display intranet sites in Compatibility View".

Click on Close. It may re-launch the page and then your problem would be resolved.

Here is where I found it on a Windows 2008R2 server. Elevated Task Scheduler Click on "Task Scheduler Library" It appears as an option on the right hand "Actions" panel.

$('li.menu.active')

is the simplest way. This will return all elements with both classes.

Or an already answered jQuery hasClass() - check for more than one class

If my compiler is set to 32 bit, size_t is nothing other than a typedef for unsigned int. If my compiler is set to 64 bit, size_t is nothing other than a typedef for unsigned long long.

If your tiles are not in your bundle, either copied from the bundle or downloaded from the internet you can get the directory like this

NSString *documentdir = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
NSString *tileDirectory = [documentdir stringByAppendingPathComponent:@"xxxx/Tiles"];
NSLog(@"Tile Directory: %@", tileDirectory);

djb2 has 317 collisions for this 466k english dictionary while MurmurHash has none for 64 bit hashes, and 21 for 32 bit hashes (around 25 is to be expected for 466k random 32 bit hashes). My recommendation is using MurmurHash if available, it is very fast, because it takes in several bytes at a time. But if you need a simple and short hash function to copy and paste to your project I'd recommend using murmurs one-byte-at-a-time version:

uint32_t inline MurmurOAAT32 ( const char * key)
{
  uint32_t h(3323198485ul);
  for (;*key;++key) {
    h ^= *key;
    h *= 0x5bd1e995;
    h ^= h >> 15;
  }
  return h;
}

uint64_t inline MurmurOAAT64 ( const char * key)
{
  uint64_t h(525201411107845655ull);
  for (;*key;++key) {
    h ^= *key;
    h *= 0x5bd1e9955bd1e995;
    h ^= h >> 47;
  }
  return h;
}

The optimal size of a hash table is - in short - as large as possible while still fitting into memory. Because we don't usually know or want to look up how much memory we have available, and it might even change, the optimal hash table size is roughly 2x the expected number of elements to be stored in the table. Allocating much more than that will make your hash table faster but at rapidly diminishing returns, making your hash table smaller than that will make it exponentially slower. This is because there is a non-linear trade-off between space and time complexity for hash tables, with an optimal load factor of 2-sqrt(2) = 0.58... apparently.

I use something like this:

if schema_id('newSchema') is null
    exec('create schema newSchema');

The advantage is if you have this code in a long sql-script you can always execute it with the other code, and its short.

"Best" as in pure performance? or performance AND readability?

Pure performance "best" is this, which uses a cache and the ++prefix operator (my data: http://jsperf.com/caching-array-length/189)

for (var i = 0, len = myArray.length; i < len; ++i) {
  // blah blah
}

I would argue that the cache-less for-loop is the best balance in execution time and programmer reading time. Every programmer that started with C/C++/Java won't waste a ms having to read through this one

for(var i=0; i < arr.length; i++){
  // blah blah
}

this.MdiParent.WindowState = FormWindowState.Minimized;

Do not forget to actually build the google-play-services_lib!! That's why it shows the "Could not find google-play....apk". For me, on Eclipse, no other hacks were needed, but to reference the project from the Android submenu, not from Java build path, or Project references or whatever else. No manually placed jars, no nothing were actually needed for me.

If you can't use the delay method as Robert Harvey suggested, you can use setTimeout.

Eg.

setTimeout(function() {$("#test").animate({"top":"-=80px"})} , 1500); // delays 1.5 sec
setTimeout(function() {$("#test").animate({"opacity":"0"})} , 1500 + 1000); // delays 1 sec after the previous one

It's not bad practice at all. They are usually referred as SUBQUERY, SUBSELECT or NESTED QUERY.

It's a relatively expensive operation, but it's quite common to encounter a lot of subqueries when dealing with databases since it's the only way to perform certain kind of operations on data.

In KitKat and above, you could use evaluateJavascript method on webview

wvbrowser.evaluateJavascript(
        "(function() { return ('<html>'+document.getElementsByTagName('html')[0].innerHTML+'</html>'); })();",
         new ValueCallback<String>() {
            @Override
            public void onReceiveValue(String html) {
                Log.d("HTML", html); 
                // code here
            }
    });

See this answer for more examples

I usually do this the following way:

def set_if_not_exists(obj,attr,value):
 if not hasattr(obj,attr): setattr(obj,attr,value)

Try this too,

private void getContactList() {
    ContentResolver cr = getContentResolver();
    Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,
            null, null, null, null);

    if ((cur != null ? cur.getCount() : 0) > 0) {
        while (cur != null && cur.moveToNext()) {
            String id = cur.getString(
                    cur.getColumnIndex(ContactsContract.Contacts._ID));
            String name = cur.getString(cur.getColumnIndex(
                    ContactsContract.Contacts.DISPLAY_NAME));

            if (cur.getInt(cur.getColumnIndex(
                    ContactsContract.Contacts.HAS_PHONE_NUMBER)) > 0) {
                Cursor pCur = cr.query(
                        ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
                        null,
                        ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?",
                        new String[]{id}, null);
                while (pCur.moveToNext()) {
                    String phoneNo = pCur.getString(pCur.getColumnIndex(
                            ContactsContract.CommonDataKinds.Phone.NUMBER));
                    Log.i(TAG, "Name: " + name);
                    Log.i(TAG, "Phone Number: " + phoneNo);
                }
                pCur.close();
            }
        }
    }
    if(cur!=null){
        cur.close();
    }
}

If you need more reference means refer this link Read ContactList

add_location.removeAllViews();

            for (int i=0;i<arrayList.size();i++)
            {
                add_location.addView(new HolderDropoff(AddDropOffActivtity.this,add_location,arrayList,AddDropOffActivtity.this,this));
            }
            add_location.getAdapter().notifyDataSetChanged();

If you don't have another time interval bigger than days:

int days = (int) (milliseconds / (1000*60*60*24));

If you have weeks too:

int days = (int) ((milliseconds / (1000*60*60*24)) % 7);
int weeks = (int) (milliseconds / (1000*60*60*24*7));

It's probably best to avoid using months and years if possible, as they don't have a well-defined fixed length. Strictly speaking neither do days: daylight saving means that days can have a length that is not 24 hours.

You can make a class for each label and inside it put:

display: inline-block;

And width the value that you need.

For those using CloudFormation template. You can set AWS_DEFAULT_REGION environment variable using UserData and AWS::Region. For example,

MyInstance1:
    Type: AWS::EC2::Instance                
    Properties:                           
        ImageId: ami-04b9e92b5572fa0d1 #ubuntu
        InstanceType: t2.micro
        UserData: 
            Fn::Base64: !Sub |
                    #!/bin/bash -x

                    echo "export AWS_DEFAULT_REGION=${AWS::Region}" >> /etc/profile

Not sure if this is cheating or not:

window.say = function(a) { alert(a); };

var a = "say('hello')";

var p = /^([^(]*)\('([^']*)'\).*$/;                 // ["say('hello')","say","hello"]

var fn = window[p.exec(a)[1]];                      // get function reference by name

if( typeof(fn) === "function") 
    fn.apply(null, [p.exec(a)[2]]);                 // call it with params

To get JSON posted without the application/json content type, use request.get_json(force=True).

@app.route('/process_data', methods=['POST'])
def process_data():
    req_data = request.get_json(force=True)
    language = req_data['language']
    return 'The language value is: {}'.format(language)

Also I use Tomcat GUI app (in my case: C:\tomcat\bin\Tomcat9w.bin).

• Go to Java tab:

  

• Set your Java properties, for example:

This will depend on the logging configuration. The default value will depend on the framework being used. The idea is that later on by changing a configuration setting from INFO to DEBUG you will see a ton of more (or less if the other way around) lines printed without recompiling the whole application.

If you think which one to use then it boils down to thinking what you want to see on which level. For other levels for example in Log4J look at the API, http://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/Level.html

ListView was intended for simple use cases like the same static view for all row items.
Since you have to create ViewHolders and make significant use of getItemViewType(), and dynamically show different row item layout xml's, you should try doing that using the RecyclerView, which is available in Android API 22. It offers better support and structure for multiple view types.

Check out this tutorial on how to use the RecyclerView to do what you are looking for.

If you just made a migration, you can rollback and then make your migration again.

To rollback you can do as many steps as you want:

rake db:rollback STEP=1

Or, if you are using Rails 5.2 or newer:

rails db:rollback STEP=1

Then, you can just make the migration again:

def change
  add_column :profiles, :show_attribute, :boolean, default: true
end

Don't forget to rake db:migrate and if you are using heroku heroku run rake db:migrate

If relative paths are what you want you can just use the -Name flag.

Get-ChildItem "C:\windows\System32" -Recurse -Filter *.txt -Name

This appears in the context of the Handle-Body-Idiom, also called Pimpl idiom. It allows one to keep the ABI (binary interface) of a library the same, by keeping actual data into another class object, which is merely referenced by a pointer held in an "handle" object, consisting of functions that delegate to that class "Body".

It's also useful to enable constant time and exception safe swap of two objects. For this, merely the pointer pointing to the body object has to be swapped.

To check whether select box has any values:

if( $('#fruit_name').has('option').length > 0 ) {

To check whether selected value is empty:

if( !$('#fruit_name').val() ) {

h = Hash[*a] # => { "item 1" => "item 2", "item 3" => "item 4" }

That's it. The * is called the splat operator.

One caveat per @Mike Lewis (in the comments): "Be very careful with this. Ruby expands splats on the stack. If you do this with a large dataset, expect to blow out your stack."

So, for most general use cases this method is great, but use a different method if you want to do the conversion on lots of data. For example, @Lukasz Niemier (also in the comments) offers this method for large data sets:

h = Hash[a.each_slice(2).to_a]

res = request.GET['paymentid'] will raise a KeyError if paymentid is not in the GET data.

Your sample php code checks to see if paymentid is in the POST data, and sets $payID to '' otherwise:

$payID = isset($_POST['paymentid']) ? $_POST['paymentid'] : ''

The equivalent in python is to use the get() method with a default argument:

payment_id = request.POST.get('payment_id', '')

while debugging, this is what I see in the response.GET: <QueryDict: {}>, request.POST: <QueryDict: {}>

It looks as if the problem is not accessing the POST data, but that there is no POST data. How are you are debugging? Are you using your browser, or is it the payment gateway accessing your page? It would be helpful if you shared your view.

Once you are managing to submit some post data to your page, it shouldn't be too tricky to convert the sample php to python.

In Python, a method is a function that is available for a given object because of the object's type.

For example, if you create my_list = [1, 2, 3], the append method can be applied to my_list because it's a Python list: my_list.append(4). All lists have an append method simply because they are lists.

As another example, if you create my_string = 'some lowercase text', the upper method can be applied to my_string simply because it's a Python string: my_string.upper().

Lists don't have an upper method, and strings don't have an append method. Why? Because methods only exist for a particular object if they have been explicitly defined for that type of object, and Python's developers have (so far) decided that those particular methods are not needed for those particular objects.

To call a method, the format is object_name.method_name(), and any arguments to the method are listed within the parentheses. The method implicitly acts on the object being named, and thus some methods don't have any stated arguments since the object itself is the only necessary argument. For example, my_string.upper() doesn't have any listed arguments because the only required argument is the object itself, my_string.

One common point of confusion regards the following:

import math
math.sqrt(81)

Is sqrt a method of the math object? No. This is how you call the sqrt function from the math module. The format being used is module_name.function_name(), instead of object_name.method_name(). In general, the only way to distinguish between the two formats (visually) is to look in the rest of the code and see if the part before the period (math, my_list, my_string) is defined as an object or a module.

You can use sed to replace lines in place in a file. However, it seems to be much slower than using grep for the inverse into a second file and then moving the second file over the original.

e.g.

sed -i '/pattern/d' filename      

or

grep -v "pattern" filename > filename2; mv filename2 filename

The first command takes 3 times longer on my machine anyway.

Use the LastLogonDate property and you won't have to convert the date/time. lastLogonTimestamp should equal to LastLogonDate when converted. This way, you will get the last logon date and time across the domain without needing to convert the result.

In my case I was missing @ at the beginning of the foreach

    @foreach (var item in Model)
    {
        <tr class="clickable-row">
            <td class="clickable-field">
                @Html.DisplayFor(modelItem => item.Label)
            </td>
            <td class="clickable-field hidden-xs">
                @Html.DisplayFor(modelItem => item.Value)
            </td>
        </tr>
    }

If you use the $.ajax function, you can simply add the csrf token in the data body:

$.ajax({
    data: {
        somedata: 'somedata',
        moredata: 'moredata',
        csrfmiddlewaretoken: '{{ csrf_token }}'
    },

The problem was actually solved by providing crossOrigin: null to OpenLayers OSM source:

var newLayer = new ol.layer.Tile({
source: new ol.source.OSM({
    url: 'E:/Maperitive/Tiles/vychod/{z}/{x}/{y}.png',
    crossOrigin: null
    })
});

Here are three different checkmark styles you can use:

ul:first-child  li:before { content:"\2713\0020"; }  /* OR */_x000D_
ul:nth-child(2) li:before { content:"\2714\0020"; }  /* OR */_x000D_
ul:last-child   li:before { content:"\2611\0020"; }_x000D_
ul { list-style-type: none; }

Just putting it out there for newbies;

So First understand Word Context :

In english-lib. it means:

"The circumstances that form the setting for an event, statement, or idea, and in terms of which it can be fully understood and assessed."

"The parts of something written or spoken that immediately precede and follow a word or passage and clarify its meaning."

Now take the same understanding to programming world:

context of current state of the application/object. It lets newly created objects understand what has been going on. Typically you call it to get information regarding another part of your program (activity, package/application)

You can get the context by invoking getApplicationContext(), getContext(), getBaseContext() or this (when in the activity class).

To Get Context Anywhere in application use following code:

Create new class AppContext inside your android application

public class AppContext extends Application {

    private static Context context;

    public void onCreate(){
        super.onCreate();
        AppContext.context = getApplicationContext();
    }

    public static Context getAppContext() {
        return AppContext.context;
    }
}

Now any time you want application context in non-activity class, call this method and you have application context.

Hope this help ;)

My solution is to pull on the other working copy and then do:

git log --pretty="format:" --name-only -n1 | xargs git checkout HEAD^1

which says get all the file paths in the latest comment, and check them out from the parent of HEAD. Job done.

The most modern answer, taken from Valloric's comment above:

1. Upgrade to Git 1.9.3 (or 2.18 if the submodule contains nested submodules)
2. git mv old/submod new/submod
3. Afterwards the .gitmodules and the submodule directory are already staged for a commit (you can verify this with git status.)
4. Commit the changes with git commitand you're good to go!

Done!

REST itself offers no security standards, but things like OAuth and SAML are rapidly becoming the standards in this space. However, authentication and authorization are only a small part of what you need to consider. Many of the known vulnerabilities relating to web applications apply very much to REST apis. You have to consider input validation, session cracking, inappropriate error messages, internal employee vulnerabilities and so on. It is a big subject.

You may not like this answer, but I think it's the RIGHT one. Don't change your stdout destination unless it's absolutely necessary (maybe you're using a library that only outputs to stdout??? clearly not the case here).

I think as a good habit you should prepare your data ahead of time as a string, then open your file and write the whole thing at once. This is because input/output operations are the longer you have a file handle open, the more likely an error is to occur with this file (file lock error, i/o error, etc). Just doing it all in one operation leaves no question for when it might have gone wrong.

Here's an example:

out_lines = []
for bamfile in bamfiles:
    filename = bamfile.split('/')[-1]
    out_lines.append('Filename: %s' % filename)
    samtoolsin = subprocess.Popen(["/share/bin/samtools/samtools","view",bamfile],
                                  stdout=subprocess.PIPE,bufsize=1)
    linelist= samtoolsin.stdout.readlines()
    print 'Readlines finished!'
    out_lines.extend(linelist)
    out_lines.append('\n')

And then when you're all done collecting your "data lines" one line per list item, you can join them with some '\n' characters to make the whole thing outputtable; maybe even wrap your output statement in a with block, for additional safety (will automatically close your output handle even if something goes wrong):

out_string = '\n'.join(out_lines)
out_filename = 'myfile.txt'
with open(out_filename, 'w') as outf:
    outf.write(out_string)
print "YAY MY STDOUT IS UNTAINTED!!!"

However if you have lots of data to write, you could write it one piece at a time. I don't think it's relevant to your application but here's the alternative:

out_filename = 'myfile.txt'
outf = open(out_filename, 'w')
for bamfile in bamfiles:
    filename = bamfile.split('/')[-1]
    outf.write('Filename: %s' % filename)
    samtoolsin = subprocess.Popen(["/share/bin/samtools/samtools","view",bamfile],
                                  stdout=subprocess.PIPE,bufsize=1)
    mydata = samtoolsin.stdout.read()
    outf.write(mydata)
outf.close()

There are few examples for using JSONP which include error handling.

However, please note that the error-event is not triggered when using JSONP! See: http://api.jquery.com/jQuery.ajax/ or jQuery ajax request using jsonp error

The bitwise shift operators move the bit values of a binary object. The left operand specifies the value to be shifted. The right operand specifies the number of positions that the bits in the value are to be shifted. The result is not an lvalue. Both operands have the same precedence and are left-to-right associative.

Operator     Usage

 <<           Indicates the bits are to be shifted to the left.

 >>           Indicates the bits are to be shifted to the right.

Each operand must have an integral or enumeration type. The compiler performs integral promotions on the operands, and then the right operand is converted to type int. The result has the same type as the left operand (after the arithmetic conversions).

The right operand should not have a negative value or a value that is greater than or equal to the width in bits of the expression being shifted. The result of bitwise shifts on such values is unpredictable.

If the right operand has the value 0, the result is the value of the left operand (after the usual arithmetic conversions).

The << operator fills vacated bits with zeros. For example, if left_op has the value 4019, the bit pattern (in 16-bit format) of left_op is:

0000111110110011

The expression left_op << 3 yields:

0111110110011000

The expression left_op >> 3 yields:

0000000111110110

After struggling much with the npm link command (suggested solution for developing local modules without publishing them to a registry or maintaining a separate copy in the node_modules folder), I built a small npm module to help with this issue.

The fix requires two easy steps.

First:

npm install lib-manager --save-dev

Second, add this to your package.json:

{  
  "name": "yourModuleName",  
  // ...
  "scripts": {
    "postinstall": "./node_modules/.bin/local-link"
  }
}

More details at https://www.npmjs.com/package/lib-manager. Hope it helps someone.

Try this. This will work. $('#baba').prop('selectedIndex',0);

Check here http://jsfiddle.net/bibin_v/R4s3U/

You can make this bit more cleaner by using:

$http.get(url)
    .then(function (response) {
        console.log('get',response)
    })
    .catch(function (data) {
        // Handle error here
    });

Similar to @this.lau_ answer, different approach.

No need to explicitly go to the end of line before doing a, use A;
Append text at the end of line [count] times

<ESC>GA

Do you mean something like:

SELECT COLUMN1, COLUMN2 FROM MY_TABLE WHERE COLUMN1 = 'Value' OR COLUMN1 IS NULL

?

Here's an alternative way to do the same call. And your type should always be in CAPS, eg. type:"GET" / type:"POST".

$.ajax({
      url:/ControllerName/ActionName,
      data: "id=" + Id + "&param2=" + param2,
      type: "GET",
      success: function(data){
            // code here
      },
      error: function(passParams){
           // code here
      }
});

Another alternative will be to use the data-ajax on a link.

<a href="/ControllerName/ActionName/" data-ajax="true" data-ajax-method="GET" data-ajax-mode="replace" data-ajax-update="#_content">Click Me!</a>

Assuming u had a div with the I'd _content, this will call the action and replace the content inside that div with the data returned from that action.

<div id="_content"></div>

Not really a direct answer to ur question but its some info u should be aware of ;).

If you're using Windows, the unix-style default path of ssh-keygen is at fault.

In Line 2 it says Enter file in which to save the key (/c/Users/Eva/.ssh/id_rsa):. That full filename in the parantheses is the default, obviously Windows cannot access a file like that. If you type the Windows equivalent (c:\Users\Eva\.ssh\id_rsa), it should work.

Before running this, you also need to create the folder. You can do this by running mkdir c:\Users\Eva\.ssh, or by created the folder ".ssh." from File Explorer (note the second dot at the end, which will get removed automatically, and is required to create a folder that has a dot at the beginning).

c:\Users\Administrator\.ssh>ssh-keygen -t rsa -C "[email protected]"

Use df.schema.names:

spark.version
# u'2.2.0'

df = spark.createDataFrame([("foo", 1), ("bar", 2)])
df.show()
# +---+---+ 
# | _1| _2|
# +---+---+
# |foo|  1| 
# |bar|  2|
# +---+---+

df.schema.names
# ['_1', '_2']

for i in df.schema.names:
  # df_new = df.withColumn(i, [do-something])
  print i
# _1

You can also try this to determine the current global sql_mode value:

SELECT @@GLOBAL.sql_mode;

or session sql_mode value:

SELECT @@SESSION.sql_mode;

I also had the feeling that the SQL mode was indeed empty.

I know this is an old question, but it is the top google result for "gitbash homedir windows" so figured I'd add my findings.

No matter what I tried I couldn't get git-bash to start in anywhere but my network drive,(U:) in my case making every operation take 15-20 seconds to respond. (Remote employee on VPN, network drive hosted on the other side of the country)

I tried setting HOME and HOMEDIR variables in windows.

I tried setting HOME and HOMEDIR variables in the git installation'setc/profile file.

I tried editing the "Start in" on the git-bash shortcut to be C:/user/myusername.

"env" command inside the git-bash shell would show correct c:/user/myusername. But git-bash would still start in U:

What ultimately fixed it for me was editing the git-bash shortcut and removing the "--cd-to-home" from the Target line.

this will set your session to keep everything till the browser is closed

session.setMaxinactiveinterval(-1);

and this should set it for 1 day

session.setMaxInactiveInterval(60*60*24);

You need to use list-style: none;

<ul style="list-style: none;">
    <li>...</li>
</ul>

I would suggest you use the below css

.showhideoverlay { 
  width: 100%;
  height: 100%;
  right: 0px;
  top: 0px;
  position: fixed;
  background: #000;
  opacity: 0.75;
}

You can then use a simple toggle function:

$('a.open').click(function() {
  $('div.showhideoverlay').toggle("slow");
});

This will display the overlay menu from right to left. Alternatively, you can use the positioning for changing the effect from top or bottom, i.e. use bottom: 0; instead of top: 0; - you will see menu sliding from right-bottom corner.

Like explained in other answers you need to provide a comparison function. If you would like to keep the definition of that function close to the sort call (e.g. if it only makes sense for this sort) you can define it right there with boost::lambda. Use boost::lambda::bind to call the member function.

To e.g. sort by member variable or function data1:

#include <algorithm>
#include <vector>
#include <boost/lambda/bind.hpp>
#include <boost/lambda/lambda.hpp>
using boost::lambda::bind;
using boost::lambda::_1;
using boost::lambda::_2;

std::vector<myclass> object(10000);
std::sort(object.begin(), object.end(),
    bind(&myclass::data1, _1) < bind(&myclass::data1, _2));

Well, reading it isn't hard, just use FileStream to read a byte[]. Converting it to text isn't really generally possible or meaningful unless you convert the 1's and 0's to hex. That's easy to do with the BitConverter.ToString(byte[]) overload. You'd generally want to dump 16 or 32 bytes in each line. You could use Encoding.ASCII.GetString() to try to convert the bytes to characters. A sample program that does this:

using System;
using System.IO;
using System.Text;

class Program {
    static void Main(string[] args) {
        // Read the file into <bits>
        var fs = new FileStream(@"c:\temp\test.bin", FileMode.Open);
        var len = (int)fs.Length;
        var bits = new byte[len];
        fs.Read(bits, 0, len);
        // Dump 16 bytes per line
        for (int ix = 0; ix < len; ix += 16) {
            var cnt = Math.Min(16, len - ix);
            var line = new byte[cnt];
            Array.Copy(bits, ix, line, 0, cnt);
            // Write address + hex + ascii
            Console.Write("{0:X6}  ", ix);
            Console.Write(BitConverter.ToString(line));
            Console.Write("  ");
            // Convert non-ascii characters to .
            for (int jx = 0; jx < cnt; ++jx)
                if (line[jx] < 0x20 || line[jx] > 0x7f) line[jx] = (byte)'.';
            Console.WriteLine(Encoding.ASCII.GetString(line));
        }
        Console.ReadLine();
    }
}

For a field separator of any number 2 through 5 or letter a or # or a space, where the separating character must be repeated at least 2 times and not more than 6 times, for example:

awk -F'[2-5a# ]{2,6}' ...

I am sure variations of this exist using ( ) and parameters

It means 'not equal to'. So you're filtering out records where ordid is 605. Overall you're looking for any records which have the same prodid and qty values as those assigned to ordid 605, but which are for a different order.

Here is another way to loop through XML elements using JDOM.

        List<Element> nodeNodes = inputNode.getChildren();
        if (nodeNodes != null) {
            for (Element nodeNode : nodeNodes) {
                List<Element> elements = nodeNode.getChildren(elementName);
                if (elements != null) {
                    elements.size();
                    nodeNodes.removeAll(elements);
                }
            }

If you know which colors you want, you can specify color properties in an array, like so:

    backgroundColor: [
    'rgba(75, 192, 192, 1)',
    ...
    ],
    borderColor: [
    'rgba(75, 192, 192, 1)',
    ...
    ],

plt.gca().axes.yaxis.set_ticklabels([])

A lot of the solutions offered here do not seem to work anymore. I'm currently on a chromebook and wanted to view an HTML5 banner. This seems impossible now through Google Drive or other apps (as mentioned in previous comments).

The method I ended up using to view the HTML5 was the following:

1. Open Google Adwords (create a free account if you dont have one)
2. Click on Ads in the top panel
3. Click on "+AD" and choose image ad
4. Choose "upload an ad"
5. Drag and drop your zip file into the area
6. Click on Preview
7. Voila, you will see your HTML5 banners in their full beauty

There may well an easier way, but this way is pretty good too. Hope it helps and worked well for me.

you could just use the floatval function

echo floatval('125.00');
// 125

echo floatval('966.70');

In my case was Promise with no reject neither resolve, because my Promise function threw an exception. This mistake cause UnhandledPromiseRejectionWarning message.

In usecase where you want to serialize/deserialize POCOs, Newtonsoft's JSON library is really good. I use it to persist POCOs within SQL Server as JSON strings in an nvarchar field. Caveat is that since its not true de/serialization, it will not preserve private/protected members and class hierarchy.

For the uninitiated who are confused by the previous answers, you can do:

git remote -v

Which will respond with something like

origin    https://[email protected]/yourname/yourrepo.git (fetch)
origin    https://[email protected]/yourname/yourrepo.git (push)

Then you can run the command many other have suggested, but now you know yourname and yourrepo from above, so you can just cut and paste yourname/yourrepo.git from the above into:

git remote set-url origin [email protected]:yourname/yourrepo.git

The Python docs for hash() state:

Hash values are integers. They are used to quickly compare dictionary keys during a dictionary lookup.

Python dictionaries are implemented as hash tables. So any time you use a dictionary, hash() is called on the keys that you pass in for assignment, or look-up.

Additionally, the docs for the dict type state:

Values that are not hashable, that is, values containing lists, dictionaries or other mutable types (that are compared by value rather than by object identity) may not be used as keys.

Create a folder named fonts in the assets folder and add the snippet from the below link.

Typeface tf = Typeface.createFromAsset(getApplicationContext().getAssets(),"fonts/fontname.ttf");
textview.setTypeface(tf);

function convertToRoman(int) {
    console.log('Number:', int);
    let roman = [];
    let i, k, replacement;
    let seq = ['I', 'V', 'X', 'L', 'C', 'D', 'M'];

    while (int > 999) {
        roman.push('M');
        int -= 1000;
    }
    while (int > 499) {
        roman.push('D');
        int -= 500;
    }
    while (int > 99) {
        roman.push('C');
        int -= 100;
    }
    while (int > 49) {
        roman.push('L');
        int -= 50;
    }
    while (int > 9) {
        roman.push('X');
        int -= 10;
    }
    while (int > 4) {
        roman.push('V');
        int -= 5;
    }
    while (int >= 1) {
        roman.push('I');
        int -= 1;
    }

    // Replace recurrences of 4 ('IIII' to 'IV')
    for (i = 0; i < roman.length; i++) {
        if (roman[i] == roman[i + 1] &&
            roman[i] == roman[i + 2] &&
            roman[i] == roman[i + 3]) {
            for (k = 0; k < seq.length; k++) {
                if (roman[i] == seq[k]) {
                    replacement = seq[k + 1];
                }
            }
            roman.splice(i + 1, 3, replacement);
        }
    }

    // Converting incorrect recurrences ('VIV' to 'IX')
    for (i = 0; i < roman.length; i++) {
        if (roman[i] == roman[i + 2] && roman[i] != roman[i + 1]) {
            for (k = 0; k < seq.length; k++) {
                if (roman[i] == seq[k]) {
                    replacement = seq[k + 1];
                }
            }
            roman[i + 2] = replacement;
            roman.splice(i, 1);
        }
    }

    roman = roman.join('');
    return roman;
}

After the merge, it's safe to delete the branch:

git branch -d branch1

Additionally, git will warn you (and refuse to delete the branch) if it thinks you didn't fully merge it yet. If you forcefully delete a branch (with git branch -D) which is not completely merged yet, you have to do some tricks to get the unmerged commits back though (see below).

There are some reasons to keep a branch around though. For example, if it's a feature branch, you may want to be able to do bugfixes on that feature still inside that branch.

If you also want to delete the branch on a remote host, you can do:

git push origin :branch1

This will forcefully delete the branch on the remote (this will not affect already checked-out repositiories though and won't prevent anyone with push access to re-push/create it).

git reflog shows the recently checked out revisions. Any branch you've had checked out in the recent repository history will also show up there. Aside from that, git fsck will be the tool of choice at any case of commit-loss in git.

No, #region does not exist in the T-SQL language.

You can get code-folding using begin-end blocks:

-- my region
begin
    -- code goes here
end

I'm not sure I'd recommend using them for this unless the code cannot be acceptably refactored by other means though!

export class ModalBody extends Component{
    rawMarkup(){
        var rawMarkup = this.props.content
        return { __html: rawMarkup };
    }
    render(){
        return(
                <div className="modal-body">
                     <span dangerouslySetInnerHTML={this.rawMarkup()} />

                </div>
            )
    }
}

In this simple example you can just put synchronized as a modifier after public in both method signatures.

More complex scenarios require other stuff.

This is most definitely a programming problem. The problem is that it cannot be programmed, per se. When P is actually zero then the concept of percentage change has no meaning. Zero to anything cannot be expressed as a rate as it is outside the definition boundary of rate. Going from 'not being' into 'being' is not a change of being, it is instead creation of being.

Use Math.Max:

int x = 3, y = 4, z = 5;
Console.WriteLine(Math.Max(Math.Max(x, y), z));

I created a custom useQuery hook

import { useLocation } from "react-router-dom";

const useQuery = (): URLSearchParams => {
  return new URLSearchParams(useLocation().search)
}

export default useQuery

Use it as

const query = useQuery();
const id = query.get("id") as string

Send it as so

history.push({  
 pathname: "/template",
 search: `id=${values.id}`,
});
                  

Here's the modern, safe one liner:

java.nio.file.Files.write(java.nio.file.Paths.get("/tmp/output.txt"), "Hello world".getBytes());

nio is a modern IO library shipped by default with the JDK 9+ so no imports or dependencies required.

I could figure out the problem. I was getting following warning on startup of eclipse.

The Maven Integration requires that Eclipse be running in a JDK, because a number of Maven core plugins are using jars from the JDk.

Please make sure the -vm option in eclipse.ini is pointing to a JDK and verify that
Installed JRE's are also using JDK installs

I changed eclipse.ini file and added following and restarted eclipse

-vm
C:/Program Files/java/jdk1.6.0_21/bin/javaw.exe

Now I can see "Maven Dependency" library included automatically in java build path.

cPanel Error logs are located in:

/usr/local/cpanel/logs/

/usr/local/apache/logs/

By default Apche logs are located inside:

/var/log/apache

or

/var/log/apache2

If anyone is using custom log location then you can check it by running this command:

cat /etc/apache2/conf/httpd.conf | grep ErrorLog

If you are getting error that apache2 directory does not exist then you can run this command to find correct location by:

whereis apache

or

whereis apache2

Should write "-exec grep " for each "-o -name "

find . -name '*.h' -exec grep -Hn "CP_Image" {} \; -o -name '*.cpp' -exec grep -Hn "CP_Image" {} \;

Or group them by ( )

find . \( -name '*.h' -o -name '*.cpp' \) -exec grep -Hn "CP_Image" {} \;

option '-Hn' show the file name and line.

You should write your own stream manipulator

• http://www.two-sdg.demon.co.uk/curbralan/papers/WritingStreamManipulators.html

cout << multi(5) << "whatever" << "lolcat";

Simply you can write the following code snippet to convert an OpenCV image into a grey scale image

import cv2
image = cv2.imread('image.jpg',0)
cv2.imshow('grey scale image',image)

Observe that the image.jpg and the code must be saved in same folder.

Note that:

• ('image.jpg') gives a RGB image
• ('image.jpg',0) gives Grey Scale Image.

Use sqlalchemy's text function to remove the interpretation of special characters:

Note the use of the function text("your_insert_statement") below. What it does is communicate to sqlalchemy that all of the questionmarks and percent signs in the passed in string should be considered as literals.

import sqlalchemy
from sqlalchemy import text
from sqlalchemy.orm import sessionmaker
from datetime import datetime
import re

engine = sqlalchemy.create_engine("mysql+mysqlconnector://%s:%s@%s/%s"
     % ("your_username", "your_password", "your_hostname_mysql_server:3306",
     "your_database"),
     pool_size=3, pool_recycle=3600)

conn = engine.connect()

myfile = open('access2.log', 'r')
lines = myfile.readlines()

penguins = []
for line in lines:
   elements = re.split('\s+', line)

   print "item: " +  elements[0]
   linedate = datetime.fromtimestamp(float(elements[0]))
   mydate = linedate.strftime("%Y-%m-%d %H:%M:%S.%f")

   penguins.append(text(
     "insert into your_table (foobar) values('%%%????')"))

for penguin in penguins:
    print penguin
    conn.execute(penguin)

conn.close()

mysql_connect("localhost", "root", "") or die(mysql_error()) ;
mysql_select_db("altabotanikk") or die(mysql_error()) ;

These are deprecated use the following..

 // Connects to your Database
            $link = mysqli_connect("localhost", "root", "", "");

and to insert data use the following

 $sql = "INSERT INTO  Table-Name (Column-Name)
VALUES ('$filename')" ;

Make sure your code follows this order-

<script src="jquery.min.js"></script>_x000D_
<script src="jquery-ui/jquery-ui.js"></script>

I had the same problem and a simple solution that I found was:

List<Object[]> results = query.getResultList();
for (Object[] result: results) {
    SomeClass something = (SomeClass)result[1];
    something.doSomething;
}

I know this is defenitly not the most elegant solution nor is it best practice but it works, at least for me.

MacVim is just Vim. Anything you are used to do in Vim will work exactly the same way in MacVim.

MacVim is more integrated in the whole OS than Vim in the Terminal or even GVim in Linux, it follows a lot of Mac OS X's conventions.

If you work mainly with GUI apps (YummyFTP + GitX + Charles, for example) you may prefer MacVim.

If you work mainly with CLI apps (ssh + svn + tcpdump, for example) you may prefer vim in the terminal.

Entering and leaving one realm (CLI) for the other (GUI) and vice-versa can be "expensive".

I use both MacVim and Vim depending on the task and the context: if I'm in CLI-land I'll just type vim filename and if I'm in GUI-land I'll just invoke Quicksilver and launch MacVim.

When I switched from TextMate I kind of liked the fact that MacVim supported almost all of the regular shortcuts Mac users are accustomed to. I added some of my own, mimiking TextMate but, since I was working in multiple environments I forced my self to learn the vim way. Now I use both MacVim and Vim almost exactly the same way. Using one or the other is just a question of context for me.

Also, like El Isra said, the default vim (CLI) in OS X is slightly outdated. You may install an up-to-date version via MacPorts or you can install MacVim and add an alias to your .profile:

alias vim='/path/to/MacVim.app/Contents/MacOS/Vim'

to have the same vim in MacVim and Terminal.app.

Another difference is that many great colorschemes out there work out of the box in MacVim but look terrible in the Terminal.app which only supports 8 colors (+ highlights) but you can use iTerm — which can be set up to support 256 colors — instead of Terminal.

So… basically my advice is to just use both.

EDIT: I didn't try it but the latest version of Terminal.app (in 10.7) is supposed to support 256 colors. I'm still on 10.6.x at work so I'll still use iTerm2 for a while.

EDIT: An even better way to use MacVim's CLI executable in your shell is to move the mvim script bundled with MacVim somewhere in your $PATH and use this command:

$ mvim -v

EDIT: Yes, Terminal.app now supports 256 colors. So if you don't need iTerm2's advanced features you can safely use the default terminal emulator.

For people, who are searching for a easier solution.

Add the UITextField inside a UIView. To simulate an inset around text field I keep 10 px left and width is 20px less than the view. For a rounded corner border around the textfield, use the view's border

viewBG.layer.cornerRadius = 8.0;
viewBG.layer.borderColor = [UIColor darkGrayColor].CGColor;
viewBG.layer.borderWidth = 1.0;

Finding of week number for each date of a month (considering Monday as beginning of the week)

Keep the first date of month contant $B$13

=WEEKNUM(B18,2)-WEEKNUM($B$13,2)+1

WEEKNUM(B18,2) - returns the week number of the date mentioned in cell B18

WEEKNUM($B$13,2) - returns the week number of the 1st date of month in cell B13

The answer, given by Alexandru is working quite nice. As he said, it is important that this "accessor"-view is added as the last element. Here is some code which did the trick for me:

        ...

        ...

            </LinearLayout>

        </LinearLayout>

    </FrameLayout>

</LinearLayout>

<!-- place a FrameLayout (match_parent) as the last child -->
<FrameLayout
    android:id="@+id/icon_frame_container"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
</FrameLayout>

</TabHost>

in Java:

final MaterialDialog materialDialog = (MaterialDialog) dialogInterface;

FrameLayout frameLayout = (FrameLayout) materialDialog
        .findViewById(R.id.icon_frame_container);

frameLayout.setOnTouchListener(
        new OnSwipeTouchListener(ShowCardActivity.this) {

I declared class B inside class A, how do I access it?

Just because you declare your struct B inside class A does not mean that an instance of class A automatically has the properties of struct B as members, nor does it mean that it automatically has an instance of struct B as a member.

There is no true relation between the two classes (A and B), besides scoping.

struct A { 
  struct B { 
    int v;
  };  

  B inner_object;
};

int
main (int argc, char *argv[]) {
  A object;
    object.inner_object.v = 123;
}

In my case this is the solving of this problem

1. Make sure you have installed the android SDK. Usually the location of SDK is located to this location

   /Users/your-user/Library/Android/sdk

2. After that cd to that directory.

3. Once you are in that directory type this command ./platform-tools/adb install your-location-of apk

Try sending the UTF-8 Charset header:

<?php header ('Content-type: text/html; charset=utf-8'); ?>

And the HTML meta:

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />

You've probably miss-typed something above that bit of code or created your own class called IPAddress. If you're using the .net one, that function should be available.

Have you tried using System.Net.IPAddress just in case?

System.Net.IPAddress ipaddress = System.Net.IPAddress.Parse("127.0.0.1");  //127.0.0.1 as an example

The docs on Microsoft's site have a complete example which works fine on my machine.

You can create your own method Equivalent to

String.IsNullOrWhiteSpace(value)

function IsNullOrWhiteSpace( value) {

    if (value== null) return true;

    return value.replace(/\s/g, '').length == 0;
}

If what you are trying to see is whether the server "exists", you can use the following:

function isValidURL(url) {
    var encodedURL = encodeURIComponent(url);
    var isValid = false;

    $.ajax({
      url: "http://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20html%20where%20url%3D%22" + encodedURL + "%22&format=json",
      type: "get",
      async: false,
      dataType: "json",
      success: function(data) {
        isValid = data.query.results != null;
      },
      error: function(){
        isValid = false;
      }
    });

    return isValid;
}

This will return a true/false indication whether the server exists.

If you want response time, a slight modification will do:

function ping(url) {
    var encodedURL = encodeURIComponent(url);
    var startDate = new Date();
    var endDate = null;
    $.ajax({
      url: "http://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20html%20where%20url%3D%22" + encodedURL + "%22&format=json",
      type: "get",
      async: false,
      dataType: "json",
      success: function(data) {
        if (data.query.results != null) {
            endDate = new Date();
        } else {
            endDate = null;
        }
      },
      error: function(){
        endDate = null;
      }
    });

    if (endDate == null) {
        throw "Not responsive...";
    }

    return endDate.getTime() - startDate.getTime();
}

The usage is then trivial:

var isValid = isValidURL("http://example.com");
alert(isValid ? "Valid URL!!!" : "Damn...");

Or:

var responseInMillis = ping("example.com");
alert(responseInMillis);

@Cebjyre. The IDE whether Enterprise Manager or Management Studio is better than anything I have seen so far for MySQL. I say 'easier to use' because I can do many things in MSSQL where MySQL has no counterparts. In MySQL I have no idea how to tune the queries by simply looking at the query plan or looking at the statistics. The index tuning wizard in MSSQL takes most of the guess work on what indexes are missing or misplaced.

One shortcoming of MySQL is there's no max size for a database. The database would just increase in size till it fills up the disk. Imagine if this disk is sharing databases with other users and suddenly all of their queries are failing because their databases can't grow. I have reported this issue to MySQL long time ago. I don't think it's fixed yet.

Just as there are printer drivers that do not connect to a printer at all but rather write to a PDF file, analogously there are virtual audio drivers available that do not connect to a physical microphone at all but can pipe input from other sources such as files or other programs.

I hope I'm not breaking any rules by recommending free/donation software, but VB-Audio Virtual Cable should let you create a pair of virtual input and output audio devices. Then you could play an MP3 into the virtual output device and then set the virtual input device as your "microphone". In theory I think that should work.

If all else fails, you could always roll your own virtual audio driver. Microsoft provides some sample code but unfortunately it is not applicable to the older Windows XP audio model. There is probably sample code available for XP too.

Change the type to submit and give it a name (and remove the useless onclick and flat out the 90's style uppercased tags/attributes).

<input type="submit" name="foo" value="A" />
<input type="submit" name="foo" value="B" />
...

The value will be available by $_POST['foo'] (if the parent <form> has a method="post").

If you are on PowerShell, use

rm -Force .git/index.lock

I've gotten this error when running a scalar function using a table value, but the Select statement in my scalar function RETURN clause was missing the "FROM table" portion. :facepalms:

If you are running under a flavor of Unix

Here is some code using java 6 to get you started:

JSONObject jo = new JSONObject();
jo.put("firstName", "John");
jo.put("lastName", "Doe");

JSONArray ja = new JSONArray();
ja.put(jo);

JSONObject mainObj = new JSONObject();
mainObj.put("employees", ja);

Edit: Since there has been a lot of confusion about put vs add here I will attempt to explain the difference. In java 6 org.json.JSONArray contains the put method and in java 7 javax.json contains the add method.

An example of this using the builder pattern in java 7 looks something like this:

JsonObject jo = Json.createObjectBuilder()
  .add("employees", Json.createArrayBuilder()
    .add(Json.createObjectBuilder()
      .add("firstName", "John")
      .add("lastName", "Doe")))
  .build();

This is standards compliant and cross-browser safe.

Example: http://jsfiddle.net/kv9pw/

var span = document.getElementById('someID');

while( span.firstChild ) {
    span.removeChild( span.firstChild );
}
span.appendChild( document.createTextNode("some new content") );

if 'empty' is not the best choice, what about this:

if (array_intersect($people, $criminals)) {...} //when found

or

if (!array_intersect($people, $criminals)) {...} //when not found

You can check undefined object using below code.

ReactObject === 'undefined'

If you are using Java, you can actually use commons-codec library

Utilities.sleep(milliseconds) creates a 'pause' in program execution, meaning it does nothing during the number of milliseconds you ask. It surely slows down your whole process and you shouldn't use it between function calls. There are a few exceptions though, at least that one that I know : in SpreadsheetApp when you want to remove a number of sheets you can add a few hundreds of millisecs between each deletion to allow for normal script execution (but this is a workaround for a known issue with this specific method). I did have to use it also when creating many sheets in a spreadsheet to avoid the Browser needing to be 'refreshed' after execution.

Here is an example :

function delsheets(){
  var ss = SpreadsheetApp.getActiveSpreadsheet();
  var numbofsheet=ss.getNumSheets();// check how many sheets in the spreadsheet
  for (pa=numbofsheet-1;pa>0;--pa){ 
    ss.setActiveSheet(ss.getSheets()[pa]);
    var newSheet = ss.deleteActiveSheet(); // delete sheets begining with the last one
    Utilities.sleep(200);// pause in the loop for 200 milliseconds
  }
  ss.setActiveSheet(ss.getSheets()[0]);// return to first sheet as active sheet (useful in 'list' function)
}
