The solution of @bunji works for me, but default options don't always give a good result. I added some useful parameter to tweak the appearance of the table.

import pandas as pd
import matplotlib.pyplot as plt
from pandas.tools.plotting import table
import numpy as np

dates = pd.date_range('20130101',periods=6)
df = pd.DataFrame(np.random.randn(6,4),index=dates,columns=list('ABCD'))

df.index = [item.strftime('%Y-%m-%d') for item in df.index] # Format date

fig, ax = plt.subplots(figsize=(12, 2)) # set size frame
ax.xaxis.set_visible(False)  # hide the x axis
ax.yaxis.set_visible(False)  # hide the y axis
ax.set_frame_on(False)  # no visible frame, uncomment if size is ok
tabla = table(ax, df, loc='upper right', colWidths=[0.17]*len(df.columns))  # where df is your data frame
tabla.auto_set_font_size(False) # Activate set fontsize manually
tabla.set_fontsize(12) # if ++fontsize is necessary ++colWidths
tabla.scale(1.2, 1.2) # change size table
plt.savefig('table.png', transparent=True)

The result:

ALTER TABLE Testing ALTER COLUMN TestDec decimal(16,1)

Just put decimal(precision, scale), replacing the precision and scale with your desired values.

I haven't done any testing with this with data in the table, but if you alter the precision, you would be subject to losing data if the new precision is lower.

Making a small tweak to the inside function and using lapply on an index instead of the actual list itself gets this doing what you want

x <- c("yes", "no", "maybe", "no", "no", "yes")
y <- c("red", "blue", "green", "green", "orange")
list.xy <- list(x=x, y=y)

WORD.C <- function(WORDS){
  require(wordcloud)

  L2 <- lapply(WORDS, function(x) as.data.frame(table(x), stringsAsFactors = FALSE))

  # Takes a dataframe and the text you want to display
  FUN <- function(X, text){
    windows() 
    wordcloud(X[, 1], X[, 2], min.freq=1)
    mtext(text, 3, padj=-4.5, col="red")  #what I'm trying that isn't working
  }

  # Now creates the sequence 1,...,length(L2)
  # Loops over that and then create an anonymous function
  # to send in the information you want to use.
  lapply(seq_along(L2), function(i){FUN(L2[[i]], names(L2)[i])})

  # Since you asked about loops
  # you could use i in seq_along(L2) 
  # instead of 1:length(L2) if you wanted to
  #for(i in 1:length(L2)){
  #  FUN(L2[[i]], names(L2)[i])
  #}
}

WORD.C(list.xy)

If I'm not mistaken you're looking for the FolderBrowserDialog (hence the naming):

var dialog = new System.Windows.Forms.FolderBrowserDialog();
System.Windows.Forms.DialogResult result = dialog.ShowDialog();

Also see this SO thread: Open directory dialog

try this

for example

DecimalFormat df = new DecimalFormat("#.##");
df.format(55.544545);

output:

55.54

HOW TO ANIMATE OPACITY WITH CSS:
this is my code:
the CSS code

.item {   
    height:200px;
    width:200px;
    background:red;
    opacity:0;
    transition: opacity 1s ease-in-out;
}

.item:hover {
    opacity: 1;
}
code {
    background: linear-gradient(to right,#fce4ed,#ffe8cc);
}

<div class="item">

</div>
<p><code> move mouse over top of this text</code></p>

or check this demo file

function vote(){
var vote = getElementById("yourOpinion")
if(this.workWithYou):
vote += 1 };

I found very good link for JSON: http://code.google.com/p/json-simple/wiki/EncodingExamples#Example_1-1_-_Encode_a_JSON_object

Here's code to add multiple JSONObjects to JSONArray.

JSONArray Obj = new JSONArray();
try {
    for(int i = 0; i < 3; i++) {
        // 1st object
        JSONObject list1 = new JSONObject();
        list1.put("val1",i+1);
        list1.put("val2",i+2);
        list1.put("val3",i+3);
        obj.put(list1);
    }

} catch (JSONException e1) {
    // TODO Auto-generated catch block
    e1.printStackTrace();
}             
Toast.makeText(MainActivity.this, ""+obj, Toast.LENGTH_LONG).show();

If the string can always be trusted, you could use eval (or use literal_eval as suggested; it's safe no matter what the string is.) Otherwise you need a parser. A JSON parser (such as simplejson) would work if he only ever stores content that fits with the JSON scheme.

Well, actually, React is not suitable for calling child methods from the parent. Some frameworks, like Cycle.js, allow easily access data both from parent and child, and react to it.

Also, there is a good chance you don't really need it. Consider calling it into existing component, it is much more independent solution. But sometimes you still need it, and then you have few choices:

• Pass method down, if it is a child (the easiest one, and it is one of the passed properties)
• add events library; in React ecosystem Flux approach is the most known, with Redux library. You separate all events into separated state and actions, and dispatch them from components
• if you need to use function from the child in a parent component, you can wrap in a third component, and clone parent with augmented props.

UPD: if you need to share some functionality which doesn't involve any state (like static functions in OOP), then there is no need to contain it inside components. Just declare it separately and invoke when need:

let counter = 0;
function handleInstantiate() {
   counter++;
}

constructor(props) {
   super(props);
   handleInstantiate();
}

After struggling with this thing for WAY too long, here is the super easy solution.

My controller was looking for

@RequestBody List<String> ids

and I had the request body as

{
    "ids": [
        "1234",
        "5678"
     ]
}

and the solution was to change the body simply to

["1234", "5678"]

Yup. Just that easy.

this should work:

table {
 border:0;
}

table td, table th {
    border: 1px solid black;
    border-collapse: collapse;
}

edit:

i just tried it, no table border. but if i set a table border it is eliminated by the border-collapse.

this is the testfile:

<html>
<head>
<style type="text/css">
table {
    border-collapse: collapse;
    border-spacing: 0;
}


table {
    border: 0;
}
table td, table th {
    border: 1px solid black;
}


</style>
</head>
<body>
<table>
    <tr>
        <th>Heading 1</th>
        <th>Heading 2</th>
    </tr>
    <tr>
        <td>Cell (1,1)</td>
        <td>Cell (1,2)</td>
    </tr>
    <tr>
        <td>Cell (2,1)</td>
        <td>Cell (2,2)</td>
    </tr>
    <tr>
        <td>Cell (3,1)</td>
        <td>Cell (3,2)</td>
    </tr>
</table>

</body>
</html>

I am using Spring STS 3.8.3. I had a similar problem. I fixed it by using information from this thread And also by fixing some maven settings. click Spring Tool Suite -> Preferences -> Maven and uncheck the box that says "Do not automatically update dependencies from remote depositories" Also I checked the boxes that say "Download Artifact Sources" and "download Artifact javadoc".

I have found something that Actually works in both FireFox and IE, on Elizabeth Castro's site (thanks to the link on this site) - I have tried all other versions here, but could not make them work in both the browsers

<object classid="CLSID:6BF52A52-394A-11d3-B153-00C04F79FAA6" 
  id="player" width="320" height="260">

    value="http://www.sarahsnotecards.com/catalunyalive/fishstore.wmv" />
  <param name="src" 
    value="http://www.sarahsnotecards.com/catalunyalive/fishstore.wmv" />
  <param name="showcontrols" value="true" />
  <param name="autostart" value="true" />
  <!--[if !IE]>-->
  <object type="video/x-ms-wmv"

  </object>
  <!--<![endif]-->
</object>

Check her site out: http://www.alistapart.com/articles/byebyeembed/ and the version with the classid in the initial object tag

This would work too:

document.getElementsByTagName('p')[0].id

(If element where the 1st paragraph in your document)

you can use @Html.Raw(str)

See MSDN for more

Returns markup that is not HTML encoded.

This method wraps HTML markup using the IHtmlString class, which renders unencoded HTML.

This is strange behavior and although I am unable to say why this is occurring, I can recommend some options.

First, an observation. If you include the image as Content in VS and copy it to the output directory, your code works. If the image is marked as None in VS and you copy it over, it doesn't work.

Solution 1: FileStream

The BitmapImage object accepts a UriSource or StreamSource as a parameter. Let's use StreamSource instead.

        FileStream stream = new FileStream("picture.png", FileMode.Open, FileAccess.Read);
        Image i = new Image();
        BitmapImage src = new BitmapImage();
        src.BeginInit();
        src.StreamSource = stream;
        src.EndInit();
        i.Source = src;
        i.Stretch = Stretch.Uniform;
        panel.Children.Add(i);

The problem: stream stays open. If you close it at the end of this method, the image will not show up. This means that the file stays write-locked on the system.

Solution 2: MemoryStream

This is basically solution 1 but you read the file into a memory stream and pass that memory stream as the argument.

        MemoryStream ms = new MemoryStream();
        FileStream stream = new FileStream("picture.png", FileMode.Open, FileAccess.Read);
        ms.SetLength(stream.Length);
        stream.Read(ms.GetBuffer(), 0, (int)stream.Length);

        ms.Flush();
        stream.Close();

        Image i = new Image();
        BitmapImage src = new BitmapImage();
        src.BeginInit();
        src.StreamSource = ms;
        src.EndInit();
        i.Source = src;
        i.Stretch = Stretch.Uniform;
        panel.Children.Add(i);

Now you are able to modify the file on the system, if that is something you require.

Here is my version based on the @peterincumbria answer:

using var scope = _serviceProvider.CreateScope();
var dbContext = scope.ServiceProvider.GetRequiredService<AppDbContext>();
return await dbContext.Database.CanConnectAsync(cToken);

I'm using Observable for polling health checking by interval and handling return value of the function. try-catch is not needed here because:

The problem seems to be a mis-placed ). In your sample you have the % outside of the print(), you should move it inside:

Use this:

print("%s. %s appears %s times." % (str(i), key, str(wordBank[key])))

The following selects all descendant elements and disables them:

$("#dcacl").find("*").prop("disabled", true);

But it only really makes sense to disable certain element types: inputs, buttons, etc., so you want a more specific selector:

$("#dcac1").find(":input").prop("disabled",true);
// noting that ":input" gives you the equivalent of
$("#dcac1").find("input,select,textarea,button").prop("disabled",true);

To re-enable you just set "disabled" to false.

I want to Disable them at loading the page and then by a click i can enable them

OK, so put the above code in a document ready handler, and setup an appropriate click handler:

$(document).ready(function() {
    var $dcac1kids = $("#dcac1").find(":input");
    $dcac1kids.prop("disabled",true);

    // not sure what you want to click on to re-enable
    $("selector for whatever you want to click").one("click",function() {
       $dcac1kids.prop("disabled",false);
    }
}

I've cached the results of the selector on the assumption that you're not adding more elements to the div between the page load and the click. And I've attached the click handler with .one() since you haven't specified a requirement to re-disable the elements so presumably the event only needs to be handled once. Of course you can change the .one() to .click() if appropriate.

I would suggest using a StreamingResponseBody since with it the application can write directly to the response (OutputStream) without holding up the Servlet container thread. It is a good approach if you are downloading a file very large.

@GetMapping("download")
public StreamingResponseBody downloadFile(HttpServletResponse response, @PathVariable Long fileId) {

    FileInfo fileInfo = fileService.findFileInfo(fileId);
    response.setContentType(fileInfo.getContentType());
    response.setHeader(
        HttpHeaders.CONTENT_DISPOSITION, "attachment;filename=\"" + fileInfo.getFilename() + "\"");

    return outputStream -> {
        int bytesRead;
        byte[] buffer = new byte[BUFFER_SIZE];
        InputStream inputStream = fileInfo.getInputStream();
        while ((bytesRead = inputStream.read(buffer)) != -1) {
            outputStream.write(buffer, 0, bytesRead);
        }
    };
}

Ps.: When using StreamingResponseBody, it is highly recommended to configure TaskExecutor used in Spring MVC for executing asynchronous requests. TaskExecutor is an interface that abstracts the execution of a Runnable.

This article from W3C tells you what they think you should do https://www.w3.org/WAI/GL/wiki/ARIATechnique_usingImgRole_with_aria-label_forCSS-backgroundImage

and has examples here http://mars.dequecloud.com/demo/ImgRole.htm

among which

<a href="http://www.facebook.com">
 <span class="fb_logo" role="img" aria-label="Connect via Facebook">
 </span>
</a>

Still, if, like in the above example, the element containing the background image is just an empty container, I personally prefer to put the text in there and hide it using CSS; right where you show the image instead:

<a href="http://www.facebook.com"><span class="fb_logo">
  Connect via Facebook
</span></a>

.fb_logo {
  height: 37px; width: 37px;
  background-image: url('../gfx/logo-facebook.svg');
  color:transparent; overflow:hidden; /* hide the text */
}

The main concept of partial view is returning the HTML code rather than going to the partial view it self.

[HttpGet]
public ActionResult Calendar(int year)
{
    var dates = new List<DateTime>() { /* values based on year */ };
    HolidayViewModel model = new HolidayViewModel {
        Dates = dates
    };
    return PartialView("HolidayPartialView", model);
}

this action return the HTML code of the partial view ("HolidayPartialView").

To refresh partial view replace the existing item with the new filtered item using the jQuery below.

$.ajax({
                url: "/Holiday/Calendar",
                type: "GET",
                data: { year: ((val * 1) + 1) }
            })
            .done(function(partialViewResult) {
                $("#refTable").html(partialViewResult);
            });

Here's a slightly different way:

SELECT *
FROM UserProfile
WHERE PropertydefinitionID in (40, 53)
  AND (LEN(ISNULL(PropertyValue,'')) = 0)

You can also use JSON.generate:

require 'json'

JSON.generate({ foo: "bar" })
=> "{\"foo\":\"bar\"}"

Or its alias, JSON.unparse:

require 'json'

JSON.unparse({ foo: "bar" })
=> "{\"foo\":\"bar\"}"

keytool -printcert -jarfile base.apk

Did you even look at the break keyword? O.o

This is just pseudo-code, but you should be able to see what I mean:

<?php
for(...) {
    while(...) {
        foreach(...) {
            break 3;
        }
    }
}

If you think about break being a function like break(), then it's parameter would be the number of loops to break out of. As we are in the third loop in the code here, we can break out of all three.

Manual: http://php.net/break

While Richard's is what you want if you do want to go with a typedef, I'd suggest that it's probably not a particularly good idea in this instance, as you lose sight of it being a pointer, while not gaining anything.

If you were treating it a a counted string, or something with additional functionality, that might be different, but I'd really recommend that in this instance, you just get familiar with the 'standard' C string implementation being a 'char *'...

Instead of using sed to filter out the certificate, you can also pipe the openssl s_client output through openssl x509 -out certfile.txt, for example:

echo "" | openssl s_client -connect my.server.com:443 -showcerts 2>/dev/null | openssl x509 -out certfile.txt

Historically, the first extensions used for C++ were .c and .h, exactly like for C. This caused practical problems, especially the .c which didn't allow build systems to easily differentiate C++ and C files.

Unix, on which C++ has been developed, has case sensitive file systems. So some used .C for C++ files. Other used .c++, .cc and .cxx. .C and .c++ have the problem that they aren't available on other file systems and their use quickly dropped. DOS and Windows C++ compilers tended to use .cpp, and some of them make the choice difficult, if not impossible, to configure. Portability consideration made that choice the most common, even outside MS-Windows.

Headers have used the corresponding .H, .h++, .hh, .hxx and .hpp. But unlike the main files, .h remains to this day a popular choice for C++ even with the disadvantage that it doesn't allow to know if the header can be included in C context or not. Standard headers now have no extension at all.

Additionally, some are using .ii, .ixx, .ipp, .inl for headers providing inline definitions and .txx, .tpp and .tpl for template definitions. Those are either included in the headers providing the definition, or manually in the contexts where they are needed.

Compilers and tools usually don't care about what extensions are used, but using an extension that they associate with C++ prevents the need to track out how to configure them so they correctly recognize the language used.

2017 edit: the experimental module support of Visual Studio recognize .ixx as a default extension for module interfaces, clang++ is recognizing .c++m, .cppm and .cxxm for the same purpose.

Whenever you create child class object then that object has all the features of parent class. Here Super() is the facilty for accession parent.

If you write super() at that time parents's default constructor is called. same if you write super.

this keyword refers the current object same as super key word facilty for accessing parents.

Another option would be using flexbox.

While it's not supported by IE8 and IE9, you could consider:

• Not minding about those old IE versions
• Providing a fallback
• Using a polyfill

Despite some additional browser-specific style prefixing would be necessary for full cross-browser support, you can see the basic usage either on this fiddle and on the following snippet:

Using the Promise pattern:

function getImage(url){
        return new Promise(function(resolve, reject){
            var img = new Image()
            img.onload = function(){
                resolve(url)
            }
            img.onerror = function(){
                reject(url)
            }
            img.src = url
        })
    }

And when calling the function we can handle its response or error quite neatly.

getImage('imgUrl').then(function(successUrl){
    //do stufff
}).catch(function(errorUrl){
    //do stuff
})

1. Go to the Graph API Explorer
2. Choose your app from the dropdown menu
3. Click "Get Access Token"
4. Choose the manage_pages permission (you may need the user_events permission too, not sure)
5. Now access the me/accounts connection and copy your page's access_token
6. Click on your page's id
7. Add the page's access_token to the GET fields
8. Call the connection you want (e.g.: PAGE_ID/events)

I ran into the same issue, for whatever reason Visual Studio did not update the web config when I first added the service. I found that updating the Service Reference also fixed this issue.

Steps:

1. Navigate to the Service Reference Folder
2. Expand it
3. Right Click and Select update Service Reference
4. Observe web Config be updated

If true -> 1 and false -> 0 mapping is what you want, you can do:

boolean b = true;
int i = b ? 1 : 0; // assigns 1 to i.

Use this code it will help you.

My way of accessing sessions is to write a helper class which encapsulates the various field names and their types. I hope this example helps:

using System;
using System.Collections.Generic;
using System.Web;
using System.Web.SessionState;

namespace dmkp
{
    /// <summary>
    /// Encapsulates the session state
    /// </summary>
    public sealed class LoginInfo
    {
        private HttpSessionState _session;
        public LoginInfo(HttpSessionState session)
        {
            this._session = session;
        }

        public string Username
        {
            get { return (this._session["Username"] ?? string.Empty).ToString(); }
            set { this._session["Username"] = value; }
        }

        public string FullName
        {
            get { return (this._session["FullName"] ?? string.Empty).ToString(); }
            set { this._session["FullName"] = value; }
        }
        public int ID
        {
            get { return Convert.ToInt32((this._session["UID"] ?? -1)); }
            set { this._session["UID"] = value; }
        }

        public UserAccess AccessLevel
        {
            get { return (UserAccess)(this._session["AccessLevel"]); }
            set { this._session["AccessLevel"] = value; }
        }

    }
}

I have windows 10 and pythonv3.5. @uku answer is correct. however, problem I was facing is that where are python scripts which are to be added in environment variable. So I found out that we need to add

C:\Users\\AppData\Local\Programs\Python\Python35\Scripts

above location as environment variable. If it still doesnot work search for python in C Drive then find out script locations.

Using JavaScript

 public ActionResult Index()
 {
    return Content("<script>window.location = 'http://www.example.com';</script>");
 }

Note: As @Jeremy Ray Brown said , This is not the best option but you might find useful in some situations.

Hope this helps.

Try without '-org':

sudo apt-get install -y mongodb

Worked for me!

line.strip() == ''

Or, if you don't want to "eat up" lines consisting of spaces:

line in ('\n', '\r\n')

For rerender you can use in parent component

<template>
  <div v-if="renderComponent">content</div>
</template>
<script>
export default {
   data() {
      return {
        renderComponent: true,
      };
    },
    methods: {
      forceRerender() {
        // Remove my-component from the DOM
        this.renderComponent = false;

        this.$nextTick(() => {
          // Add the component back in
          this.renderComponent = true;
        });
      }
    }
}
</script>

After the first if statement instead of typing "if" type "elif" and then it should work.

Ex.

`    while 1:
    date=input("Example: March 21 | What is the date? ")
if date=="June 21":
    sd="23.5° North Latitude
elif date=="March 21" | date=="September 21":
    sd="0° Latitude"
elif date=="December 21":
    sd="23.5° South Latitude"
elif sd:
    print sd `

You can set the outerdiv's CSS to this

#outerdiv {
    overflow: hidden; /* make sure this doesn't cause unexpected behaviour */
}

You can also do this by adding an element at the end with clear: both. This can be added normally, with JS (not a good solution) or with :after CSS pseudo element (not widely supported in older IEs).

The problem is that containers won't naturally expand to include floated children. Be warned with using the first example, if you have any children elements outside the parent element, they will be hidden. You can also use 'auto' as the property value, but this will invoke scrollbars if any element appears outside.

You can also try floating the parent container, but depending on your design, this may be impossible/difficult.

If the DataFrame is huge, and the number of rows to drop is large as well, then simple drop by index df.drop(df.index[]) takes too much time.

In my case, I have a multi-indexed DataFrame of floats with 100M rows x 3 cols, and I need to remove 10k rows from it. The fastest method I found is, quite counterintuitively, to take the remaining rows.

Let indexes_to_drop be an array of positional indexes to drop ([1, 2, 4] in the question).

indexes_to_keep = set(range(df.shape[0])) - set(indexes_to_drop)
df_sliced = df.take(list(indexes_to_keep))

In my case this took 20.5s, while the simple df.drop took 5min 27s and consumed a lot of memory. The resulting DataFrame is the same.

or even a very classic old fashion method

IEnumerable<string> collection = new List<string>() { "a", "b", "c" };

for(int i = 0; i < collection.Count(); i++) 
{
    string str1 = collection.ElementAt(i);
    // do your stuff   
}

maybe you would like this method also :-)

Cascade will work when you delete something on table Courses. Any record on table BookCourses that has reference to table Courses will be deleted automatically.

But when you try to delete on table BookCourses only the table itself is affected and not on the Courses

follow-up question: why do you have CourseID on table Category?

Maybe you should restructure your schema into this,

CREATE TABLE Categories 
(
  Code CHAR(4) NOT NULL PRIMARY KEY,
  CategoryName VARCHAR(63) NOT NULL UNIQUE
);

CREATE TABLE Courses 
(
  CourseID INT NOT NULL PRIMARY KEY,
  BookID INT NOT NULL,
  CatCode CHAR(4) NOT NULL,
  CourseNum CHAR(3) NOT NULL,
  CourseSec CHAR(1) NOT NULL,
);

ALTER TABLE Courses
ADD FOREIGN KEY (CatCode)
REFERENCES Categories(Code)
ON DELETE CASCADE;

Non VBA Solution:

Use Conditional Formatting rule with formula: =ISNA(A1) (to highlight cells with all errors - not only #N/A, use =ISERROR(A1))

VBA Solution:

Your code loops through 50 mln cells. To reduce number of cells, I use .SpecialCells(xlCellTypeFormulas, 16) and .SpecialCells(xlCellTypeConstants, 16)to return only cells with errors (note, I'm using If cell.Text = "#N/A" Then)

Sub ColorCells()
    Dim Data As Range, Data2 As Range, cell As Range
    Dim currentsheet As Worksheet

    Set currentsheet = ActiveWorkbook.Sheets("Comparison")

    With currentsheet.Range("A2:AW" & Rows.Count)
        .Interior.Color = xlNone
        On Error Resume Next
        'select only cells with errors
        Set Data = .SpecialCells(xlCellTypeFormulas, 16)
        Set Data2 = .SpecialCells(xlCellTypeConstants, 16)
        On Error GoTo 0
    End With

    If Not Data2 Is Nothing Then
        If Not Data Is Nothing Then
            Set Data = Union(Data, Data2)
        Else
            Set Data = Data2
        End If
    End If

    If Not Data Is Nothing Then
        For Each cell In Data
            If cell.Text = "#N/A" Then
               cell.Interior.ColorIndex = 4
            End If
        Next
    End If
End Sub

Note, to highlight cells witn any error (not only "#N/A"), replace following code

If Not Data Is Nothing Then
   For Each cell In Data
       If cell.Text = "#N/A" Then
          cell.Interior.ColorIndex = 3
       End If
   Next
End If

with

If Not Data Is Nothing Then Data.Interior.ColorIndex = 3

UPD: (how to add CF rule through VBA)

Sub test()
    With ActiveWorkbook.Sheets("Comparison").Range("A2:AW" & Rows.Count).FormatConditions
        .Delete
        .Add Type:=xlExpression, Formula1:="=ISNA(A1)"
        .Item(1).Interior.ColorIndex = 3
    End With
End Sub

I am using Camel route umarshal(xmljson) -> to(xlst) -> marshal(xmljson). Efficient enough (though not 100% perfect), but simple, if you are already using Camel.

The accepted answer reflects the rules given by Royal Mail, although there is a typo in the regex. This typo seems to have been in there on the gov.uk site as well (as it is in the XML archive page).

In the format A9A 9AA the rules allow a P character in the third position, whilst the regex disallows this. The correct regex would be:

(GIR 0AA)|((([A-Z-[QVX]][0-9][0-9]?)|(([A-Z-[QVX]][A-Z-[IJZ]][0-9][0-9]?)|(([A-Z-[QVX]][0-9][A-HJKPSTUW])|([A-Z-[QVX]][A-Z-[IJZ]][0-9][ABEHMNPRVWXY])))) [0-9][A-Z-[CIKMOV]]{2}) 

Shortening this results in the following regex (which uses Perl/Ruby syntax):

(GIR 0AA)|([A-PR-UWYZ](([0-9]([0-9A-HJKPSTUW])?)|([A-HK-Y][0-9]([0-9ABEHMNPRVWXY])?))\s?[0-9][ABD-HJLNP-UW-Z]{2})

It also includes an optional space between the first and second block.

Here is what needs to go in D1: =VLOOKUP(C1, $A$1:$B$4, 2, FALSE)

You should then be able to copy this down to the rest of column D.

Thanks to @sehe for the one-line escape:

var escaped = new System.Xml.Linq.XText(unescaped).ToString();

I add to it the one-line un-escape:

var unescapedAgain = System.Xml.XmlReader.Create(new StringReader("<r>" + escaped + "</r>")).ReadElementString();

Use the ViewPager.onPageChangeListener:

viewPager.addOnPageChangeListener(new OnPageChangeListener() {
    public void onPageScrollStateChanged(int state) {}
    public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {}

    public void onPageSelected(int position) {
        // Check if this is the page you want.
    }
});

There's no reason I can come up with that it shouldn't be possible to do through an attribute. It might be in Microsoft's backlog. Who knows.

The best solution I have found is to use the defaultValueSql parameter in the code first migration.

CreateTable(
    "dbo.SomeTable",
    c => new
        {
            TheDateField = c.DateTime(defaultValueSql: "GETDATE()")
        });

I don't like the often reference solution of setting it in the entity class constructor because if anything other than Entity Framework sticks a record in that table, the date field won't get a default value. And the idea of using a trigger to handle that case just seems wrong to me.

It is possible to load the second version of the jQuery use it and then restore to the original or keep the second version if there was no jQuery loaded before. Here is an example:

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js"></script>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.4/jquery.min.js"></script>
<script type="text/javascript">
    var jQueryTemp = jQuery.noConflict(true);
    var jQueryOriginal = jQuery || jQueryTemp;
    if (window.jQuery){
        console.log('Original jQuery: ', jQuery.fn.jquery);
        console.log('Second jQuery: ', jQueryTemp.fn.jquery);
    }
    window.jQuery = window.$ = jQueryTemp;
</script>
<script type="text/javascript">
    console.log('Script using second: ', jQuery.fn.jquery);
</script>
<script type="text/javascript">
    // Restore original jQuery:
    window.jQuery = window.$ = jQueryOriginal;
    console.log('Script using original or the only version: ', jQuery.fn.jquery);
</script>

In SSMS:

• Right click on the database > Tasks > Generate Scripts

• Next

• Select "Select specific database objects" and check the table you want scripted, Next

• Click Advanced > in the list of options, scroll down to the bottom and look for the "Types of data to script" and change it to "Data Only" > OK

• Select "Save to new query window" > Next > Next > Finish

All 180 rows now written as 180 insert statements!

If you want to use something similar to the JavaScript, you just need to convert to strings first:

Console.WriteLine(mon.ToString() + "." + da.ToString() + "." + yer.ToString());

But a (much) better way would be to use the format option:

Console.WriteLine("{0}.{1}.{2}", mon, da, yer);

What do you mean by converting?

• casting*: (int) $float or intval($float)
• truncating: floor($float) (down) or ceil($float) (up)
• rounding: round($float) - has additional modes, see PHP_ROUND_HALF_... constants

*: casting has some chance, that float values cannot be represented in int (too big, or too small), f.ex. in your case.

PHP_INT_MAX: The largest integer supported in this build of PHP. Usually int(2147483647).

But, you could use the BCMath, or the GMP extensions for handling these large numbers. (Both are boundled, you only need to enable these extensions)

Even better, try an OrderedDict (assuming you want something like a list). Closer to a list than a regular dict since the keys have an order just like list elements have an order. With a regular dict, the keys have an arbitrary order.

Note that this is available in Python 3 and 2.7. If you want to use with an earlier version of Python you can find installable modules to do that.

Generally, it's considered a bad practice to style standard form controls because the output looks so different on each browser. See: http://www.456bereastreet.com/lab/styling-form-controls-revisited/select-single/ for some rendered examples.

That being said, I've had some luck making the background color an RGBA value:

<!DOCTYPE html>
<html>
  <head>
    <style>
      body {
        background: #d00;
      }
      select {
        background: rgba(255,255,255,0.1) url('http://www.google.com/images/srpr/nav_logo6g.png') repeat-x 0 0; 
        padding:4px; 
        line-height: 21px;
        border: 1px solid #fff;
      }
    </style>
  </head>
  <body>
    <select>
      <option>Foo</option>
      <option>Bar</option>      
      <option>Something longer</option>     
  </body>
</html>

Google Chrome still renders a gradient on top of the background image in the color that you pass to rgba(r,g,b,0.1) but choosing a color that compliments your image and making the alpha 0.1 reduces the effect of this.

I added web.config to the specific folder say "Users" (VS 2015, C#) and the added following code

<?xml version="1.0"?>
 <configuration>
  <system.web>
    <authorization>     
    <deny users="?"/>
  </authorization>
</system.web>
</configuration>

Initially i used location tag but that didn't worked.

If you use jQuery UI, there is a method for that, but it can only handle mouse selection (i.e. CTRL+A is still working):

$('.your-element').disableSelection(); // deprecated in jQuery UI 1.9

The code is realy simple, if you don't want to use jQuery UI :

$(el).attr('unselectable','on')
     .css({'-moz-user-select':'-moz-none',
           '-moz-user-select':'none',
           '-o-user-select':'none',
           '-khtml-user-select':'none', /* you could also put this in a class */
           '-webkit-user-select':'none',/* and add the CSS class here instead */
           '-ms-user-select':'none',
           'user-select':'none'
     }).bind('selectstart', function(){ return false; });

This works for me:

java.util.Date d = new SimpleDateFormat("yyyy-MM-dd").parse(localDate.toString());

https://docs.oracle.com/javase/8/docs/api/java/time/LocalDate.html#toString--

Yes, that is one way to get the first line of output from a command.

If the command outputs anything to standard error that you would like to capture in the same manner, you need to redirect the standard error of the command to the standard output stream:

utility 2>&1 | head -n 1

There are many other ways to capture the first line too, including sed 1q (quit after first line), sed -n 1p (only print first line, but read everything), awk 'FNR == 1' (only print first line, but again, read everything) etc.

Okay If you want to change the gutter inside one row, but want those (first and last) inner divs to align with the grid surrounding the .no-gutter row, you could copy-paste-merge most answers into the following snippet:

.row.no-gutter [class*='col-']:first-child:not(:only-child) {
    padding-right: 0;
}
.row.no-gutter [class*='col-']:last-child:not(:only-child) {
    padding-left: 0;
}
.row.no-gutter [class*='col-']:not(:first-child):not(:last-child):not(:only-child) {
    padding-right: 0;
    padding-left: 0;
}

If you like to have a smaller gutter instead of completly none, just change the 0's to what you like... (eg: 5px to get 10px gutter).

CSS to detect screen orientation:

 @media screen and (orientation:portrait) { … }
 @media screen and (orientation:landscape) { … }

The CSS definition of a media query is at http://www.w3.org/TR/css3-mediaqueries/#orientation

Read the Request.Form NameValueCollection and process your logic accordingly:

NameValueCollection nvc = Request.Form;
string userName, password;
if (!string.IsNullOrEmpty(nvc["txtUserName"]))
{
  userName = nvc["txtUserName"];
}

if (!string.IsNullOrEmpty(nvc["txtPassword"]))
{
  password = nvc["txtPassword"];
}

//Process login
CheckLogin(userName, password);

... where "txtUserName" and "txtPassword" are the Names of the controls on the posting page.

Here is a small snippet of I made for this purpose,

var fs = require('fs');
var gutil = require('gulp-util');

fs.exists('./www/index.html', function(exists) {
  if(exists) {
    //Show in green
    console.log(gutil.colors.green('File exists. Deleting now ...'));
    fs.unlink('./www/index.html');
  } else {
    //Show in red
    console.log(gutil.colors.red('File not found, so not deleting.'));
  }
});

The code

This Gist by Eldon McGuinness is by far the most complete implementation of a JavaScript query string parser that I've seen so far.

Unfortunately, it's written as a jQuery plugin.

I rewrote it to vanilla JS and made a few improvements :

function parseQuery(str) {
  var qso = {};
  var qs = (str || document.location.search);
  // Check for an empty querystring
  if (qs == "") {
    return qso;
  }
  // Normalize the querystring
  qs = qs.replace(/(^\?)/, '').replace(/;/g, '&');
  while (qs.indexOf("&&") != -1) {
    qs = qs.replace(/&&/g, '&');
  }
  qs = qs.replace(/([\&]+$)/, '');
  // Break the querystring into parts
  qs = qs.split("&");
  // Build the querystring object
  for (var i = 0; i < qs.length; i++) {
    var qi = qs[i].split("=");
    qi = qi.map(function(n) {
      return decodeURIComponent(n)
    });
    if (typeof qi[1] === "undefined") {
      qi[1] = null;
    }
    if (typeof qso[qi[0]] !== "undefined") {

      // If a key already exists then make this an object
      if (typeof (qso[qi[0]]) == "string") {
        var temp = qso[qi[0]];
        if (qi[1] == "") {
          qi[1] = null;
        }
        qso[qi[0]] = [];
        qso[qi[0]].push(temp);
        qso[qi[0]].push(qi[1]);

      } else if (typeof (qso[qi[0]]) == "object") {
        if (qi[1] == "") {
          qi[1] = null;
        }
        qso[qi[0]].push(qi[1]);
      }
    } else {
      // If no key exists just set it as a string
      if (qi[1] == "") {
        qi[1] = null;
      }
      qso[qi[0]] = qi[1];
    }
  }
  return qso;
}

How to use it

var results = parseQuery("?foo=bar&foo=boo&roo=bar;bee=bop;=ghost;=ghost2;&;checkbox%5B%5D=b1;checkbox%5B%5D=b2;dd=;http=http%3A%2F%2Fw3schools.com%2Fmy%20test.asp%3Fname%3Dst%C3%A5le%26car%3Dsaab&http=http%3A%2F%2Fw3schools2.com%2Fmy%20test.asp%3Fname%3Dst%C3%A5le%26car%3Dsaab");

Output

{
  "foo": ["bar", "boo" ],
  "roo": "bar",
  "bee": "bop",
  "": ["ghost", "ghost2"],
  "checkbox[]": ["b1", "b2"],
  "dd": null,
  "http": [
    "http://w3schools.com/my test.asp?name=ståle&car=saab",
    "http://w3schools2.com/my test.asp?name=ståle&car=saab"
  ]
}

Here's a twist on the solution provided by @Anatoliy.

I needed to generate only light colours (for backgrounds), so I went with three letter (#AAA) format:

function get_random_color() {
    var letters = 'ABCDE'.split('');
    var color = '#';
    for (var i=0; i<3; i++ ) {
        color += letters[Math.floor(Math.random() * letters.length)];
    }
    return color;
}

Try this:

Response.Redirect(Request.Url.AbsoluteUri);

A version that avoids creating a sub-process:

for D in *; do
    if [ -d "${D}" ]; then
        echo "${D}"   # your processing here
    fi
done

Or, if your action is a single command, this is more concise:

for D in *; do [ -d "${D}" ] && my_command; done

Or an even more concise version (thanks @enzotib). Note that in this version each value of D will have a trailing slash:

for D in */; do my_command; done

if anyone needs this for NGINX configuration file here is the snippet:

location ~* \.(js|css|xml|gz)$ {
    add_header Vary "Accept-Encoding";
    (... other headers or rules ...)
}

You are not passing the array as copy. It is only a pointer pointing to the address where the first element of the array is in memory.

document.write() doesn't work with XHTML. It's executed after the page has finished loading and does nothing more than write out a string of HTML.

Since the actual in-memory representation of HTML is the DOM, the best way to update a given page is to manipulate the DOM directly.

The way you'd go about doing this would be to programmatically create your nodes and then attach them to an existing place in the DOM. For [purposes of a contrived] example, assuming that I've got a div element maintaining an ID attribute of "header," then I could introduce some dynamic text by doing this:

// create my text
var sHeader = document.createTextNode('Hello world!');

// create an element for the text and append it
var spanHeader = document.createElement('span');
spanHeader.appendChild(sHeader);

// grab a reference to the div header
var divHeader = document.getElementById('header');

// append the new element to the header
divHeader.appendChild(spanHeader);

If you have a usual pointer (A*) then the destructor will not be called (and memory for A instance will not be freed either) unless you do delete explicitly in B's destructor. If you want automatic destruction look at smart pointers like auto_ptr.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">

<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/" debug="false">

   <appender name="fileAppender" class="org.apache.log4j.RollingFileAppender">
      <param name="Threshold" value="INFO" />
      <param name="File" value="sample.log"/>
      <layout class="org.apache.log4j.PatternLayout">

</log4j:configuration>

Log4j can be a bit confusing. So lets try to understand what is going on in this file: In log4j you have two basic constructs appenders and loggers.

Appenders define how and where things are appended. Will it be logged to a file, to the console, to a database, etc.? In this case you are specifying that log statements directed to fileAppender will be put in the file sample.log using the pattern specified in the layout tags. You could just as easily create a appender for the console or the database. Where the console appender would specify things like the layout on the screen and the database appender would have connection details and table names.

Loggers respond to logging events as they bubble up. If an event catches the interest of a specific logger it will invoke its attached appenders. In the example below you have only one logger the root logger - which responds to all logging events by default. In addition to the root logger you can specify more specific loggers that respond to events from specific packages. These loggers can have their own appenders specified using the appender-ref tags or will otherwise inherit the appenders from the root logger. Using more specific loggers allows you to fine tune the logging level on specific packages or to direct certain packages to other appenders.

So what this file is saying is:

1. Create a fileAppender that logs to file sample.log
2. Attach that appender to the root logger.
3. The root logger will respond to any events at least as detailed as 'debug' level
4. The appender is configured to only log events that are at least as detailed as 'info'

The net out is that if you have a logger.debug("blah blah") in your code it will get ignored. A logger.info("Blah blah"); will output to sample.log.

The snippet below could be added to the file above with the log4j tags. This logger would inherit the appenders from <root> but would limit the all logging events from the package org.springframework to those logged at level info or above.

  <!-- Example Package level Logger -->
    <logger name="org.springframework">
        <level value="info"/>
    </logger>   

I had the same issue with multiple projects in the same solution, i ended up setting all of the target frameworks to .NET Framework 4 and x86 for the target CPU and it finally successfully compiled.

you can use Session.Remove() method; Session.Remove

Session.Remove("yourSessionName");

stdbool.h defines macros true and false, but remember they are defined to be 1 and 0.

That is why sizeof(true) is 4.

This is what I do on mine

$(document).ready(function() {
  if ($('#userForm').valid()) {
    var formData = $("#userForm").serializeArray();
    $.ajax({
      url: 'http://www.example.com/user/' + $('#Id').val() + '?callback=?',
      type: "GET",
      data: formData,
      dataType: "jsonp",
      jsonpCallback: "localJsonpCallback"
    });
  });

function localJsonpCallback(json) {
  if (!json.Error) {
    $('#resultForm').submit();
  } else {
    $('#loading').hide();
    $('#userForm').show();
    alert(json.Message);
  }
}

function urlExists($url=NULL)  
{  
    if($url == NULL) return false;  
    $ch = curl_init($url);  
    curl_setopt($ch, CURLOPT_TIMEOUT, 5);  
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 5);  
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);  
    $data = curl_exec($ch);  
    $httpcode = curl_getinfo($ch, CURLINFO_HTTP_CODE);  
    curl_close($ch);  
    if($httpcode>=200 && $httpcode<300){  
        return true;  
    } else {  
        return false;  
    }

This was grabbed from this post on how to check if a URL exists. Because Twitter should provide an error message above 300 when it is in maintenance, or a 404, this should work perfectly.

Jersey makes the process very easy, my service class worked well with JSON, all I had to do is to add the dependencies in the pom.xml

@Path("/customer")
public class CustomerService {

    private static Map<Integer, Customer> customers = new HashMap<Integer, Customer>();

    @POST
    @Path("save")
    @Consumes(MediaType.APPLICATION_JSON)
    @Produces(MediaType.APPLICATION_JSON)
    public SaveResult save(Customer c) {

        customers.put(c.getId(), c);

        SaveResult sr = new SaveResult();
        sr.sucess = true;
        return sr;
    }

    @GET
    @Produces(MediaType.APPLICATION_JSON)
    @Path("{id}")
    public Customer getCustomer(@PathParam("id") int id) {
        Customer c = customers.get(id);
        if (c == null) {
            c = new Customer();
            c.setId(id * 3);
            c.setName("unknow " + id);
        }
        return c;
    }
}

And in the pom.xml

As you explicitly state that you want obscurity not security, we'll avoid reprimanding you for the weakness of what you suggest :)

So, using PyCrypto:

import base64
from Crypto.Cipher import AES

msg_text = b'test some plain text here'.rjust(32)
secret_key = b'1234567890123456'

cipher = AES.new(secret_key,AES.MODE_ECB) # never use ECB in strong systems obviously
encoded = base64.b64encode(cipher.encrypt(msg_text))
print(encoded)
decoded = cipher.decrypt(base64.b64decode(encoded))
print(decoded)

If someone gets a hold of your database and your code base, they will be able to decode the encrypted data. Keep your secret_key safe!

If you really need this you can achieve your goal with help of separate table for sequencing (if you don't mind) and a trigger.

Tables

CREATE TABLE table1_seq
(
  id INT NOT NULL AUTO_INCREMENT PRIMARY KEY
);
CREATE TABLE table1
(
  id VARCHAR(7) NOT NULL PRIMARY KEY DEFAULT '0', name VARCHAR(30)
);

Now the trigger

DELIMITER $$
CREATE TRIGGER tg_table1_insert
BEFORE INSERT ON table1
FOR EACH ROW
BEGIN
  INSERT INTO table1_seq VALUES (NULL);
  SET NEW.id = CONCAT('LHPL', LPAD(LAST_INSERT_ID(), 3, '0'));
END$$
DELIMITER ;

Then you just insert rows to table1

INSERT INTO Table1 (name) 
VALUES ('Jhon'), ('Mark');

And you'll have

|      ID | NAME |
------------------
| LHPL001 | Jhon |
| LHPL002 | Mark |

Here is SQLFiddle demo

Try this:

System.Net.ServicePointManager.SecurityProtocol = System.Net.SecurityProtocolType.Tls12;

Notice that you have to work at least with 4.5 .NET framework

Instead of removing all assertions, you should still check for things like a person being his/her own parent or other impossible situations and present an error. Maybe issue a warning if it is unlikely so the user can still detect common input errors, but it will work if everything is correct.

I would store the data in a vector with a permanent integer for each person and store the parents and children in person objects where the said int is the index of the vector. This would be pretty fast to go between generations (but slow for things like name searches). The objects would be in order of when they were created.

also you can use this :

    if (! $('#leftmenu').children().length > 0 ) {
         // do something : e.x : remove a specific div
    }

I think it'll work for you !

Check file permissions of the /var/www/html and the ALLOW directive in your apache conf

Make sure all files are readable by the webserver and the allow directive is like

 <Directory "/var/www/html">
    Order allow,deny
    Allow from all
  </Directory>

if you can see files then consider sorting the directive to be more restrictive

Quoting directly from the help page for factor:

To transform a factor f to its original numeric values, as.numeric(levels(f))[f] is recommended and slightly more efficient than as.numeric(as.character(f)).

Somewhere in your initialisation put this code.

Array.prototype.contains = function contains(obj) {
    for (var i = 0; i < this.length; i++) {
        if (this[i] === obj) {
            return true;
        }
    }
    return false;
};

Then, you can use it this way:

<li ng-class="{approved: selectedForApproval.contains(jobSet)}"></li>

You're allowed to have more than one return statement, so it's legal to write

if (some_condition) {
  return true;
}
return false;

It's also unnecessary to compare boolean values to true or false, so you can write

if (verifyPwd())  {
  // do_task
}

Edit: Sometimes you can't return early because there's more work to be done. In that case you can declare a boolean variable and set it appropriately inside the conditional blocks.

boolean success = true;

if (some_condition) {
  // Handle the condition.
  success = false;
} else if (some_other_condition) {
  // Handle the other condition.
  success = false;
}
if (another_condition) {
  // Handle the third condition.
}

// Do some more critical things.

return success;

The problem was that the working copy was checked out via svn+ssh (thanks, Thomas). Instead of setting up ssh keys as was suggested, I just checked out a new working copy using svn://domain.com/path/to/repo rather than svn+ssh://domain.com/path/to/repo. Because this working copy is on the same machine as the repository itself, I'm not really missing out on anything, and I can now use the --password and --username options gratuitously. Seems obvious now that I think about it.

I tested the ByteBuffer method against plain bitwise operations but the latter is significantly faster.

public static byte[] longToBytes(long l) {
    byte[] result = new byte[8];
    for (int i = 7; i >= 0; i--) {
        result[i] = (byte)(l & 0xFF);
        l >>= 8;
    }
    return result;
}

public static long bytesToLong(final byte[] b) {
    long result = 0;
    for (int i = 0; i < 8; i++) {
        result <<= 8;
        result |= (b[i] & 0xFF);
    }
    return result;
}

For Java 8+ we can use the static variables that were added:

public static byte[] longToBytes(long l) {
    byte[] result = new byte[Long.BYTES];
    for (int i = Long.BYTES - 1; i >= 0; i--) {
        result[i] = (byte)(l & 0xFF);
        l >>= Byte.SIZE;
    }
    return result;
}

public static long bytesToLong(final byte[] b) {
    long result = 0;
    for (int i = 0; i < Long.BYTES; i++) {
        result <<= Byte.SIZE;
        result |= (b[i] & 0xFF);
    }
    return result;
}

SELECT TOP 1 column_name, LEN(column_name) AS Lenght FROM table_name ORDER BY LEN(column_name) DESC

You can convert datetime to string.

published_at = "{}".format(self.published_at)

What do you actually want to achieve? What your code does is it tries to connect to a server located at 192.168.1.104:4000. Is this the address of a server that sends the messages (because this looks like a client-side code)? If I run fake server locally:

$ nc -l 4000

...and change socket address to localhost:4000, it will work and try to read something from nc-created server.

What you probably want is to create a ServerSocket and listen on it:

ServerSocket serverSocket = new ServerSocket(4000);
Socket socket = serverSocket.accept();

The second line will block until some other piece of software connects to your machine on port 4000. Then you can read from the returned socket. Look at this tutorial, this is actually a very broad topic (threading, protocols...)

• If you have multiple windows open and only want to close the one that was closed use JFrame.dispose().

• If you want to close all windows and terminate the application use System.exit()

We can remove unnecessary string input in front of the value.

string convert = hdnImage.Replace("data:image/png;base64,", String.Empty);

byte[] image64 = Convert.FromBase64String(convert);

You can use the with template tag.

{% with name="World" %}     
<html>
<div>Hello {{name}}!</div>
</html>
{% endwith %}

In my case, I could not get the answer by @Sampson to work for me, at best I got a single column centered on the page. In the process however, I learned how the float actually works and created this solution. At it's core the fix is very simple but hard to find as evident by this thread which has had more than 146k views at the time of this post without mention.

All that is needed is to total the amount of screen space width that the desired layout will occupy then make the parent the same width and apply margin:auto. That's it!

The elements in the layout will dictate the width and height of the "outer" div. Take each "myFloat" or element's width or height + its borders + its margins and its paddings and add them all together. Then add the other elements together in the same fashion. This will give you the parent width. They can all be somewhat different sizes and you can do this with fewer or more elements.

Ex.(each element has 2 sides so border, margin and padding get multiplied x2)

So an element that has a width of 10px, border 2px, margin 6px, padding 3px would look like this: 10 + 4 + 12 + 6 = 32

Then add all of your element's totaled widths together.

Element 1 = 32
Element 2 = 24
Element 3 = 32
Element 4 = 24

In this example the width for the "outer" div would be 112.

.outer {_x000D_
  /* floats + margins + borders = 270 */_x000D_
  max-width: 270px;_x000D_
  margin: auto;_x000D_
  height: 80px;_x000D_
  border: 1px;_x000D_
  border-style: solid;_x000D_
}_x000D_
_x000D_
.myFloat {_x000D_
    /* 3 floats x 50px = 150px */_x000D_
    width: 50px;_x000D_
    /* 6 margins x 10px = 60 */_x000D_
    margin: 10px;_x000D_
    /* 6 borders x 10px = 60 */_x000D_
    border: 10px solid #6B6B6B;_x000D_
    float: left;_x000D_
    text-align: center;_x000D_
    height: 40px;_x000D_
}

<div class="outer">_x000D_
  <div class="myFloat">Float 1</div>_x000D_
  <div class="myFloat">Float 2</div>_x000D_
  <div class="myFloat">Float 3</div>_x000D_
</div>

You can use DDC (Domain Directory Controller). It is a new, easy to use, Java SDK. You don't even need to know LDAP to use it. It exposes an object-oriented API instead.

You can find it here.

One I use (notice this doesnt make "TestString" as "T est String" or " Test String").

function seperateCapitalised(capitalisedString) {
    if (typeof capitalisedString !== "string" || capitalisedString.length === 0)
        return capitalisedString;

    var newStr = capitalisedString[0];
    for (var i = 1; i < capitalisedString.length; i++) {
        var char = capitalisedString[i];

        if (char === char.toUpperCase() && isNaN(char)) {
            newStr += ' ' + char;
        }
        else {
            newStr += char;
        }
    }
    return newStr;
}

Try

location ~ ^/(first/location|second/location)/ {
  ...
}

The ~ means to use a regular expression for the url. The ^ means to check from the first character. This will look for a / followed by either of the locations and then another /.

You can only use await in an async method, and Main cannot be async.

You'll have to use your own async-compatible context, call Wait on the returned Task in the Main method, or just ignore the returned Task and just block on the call to Read. Note that Wait will wrap any exceptions in an AggregateException.

If you want a good intro, see my async/await intro post.

Windows Users Only

This is a bit late but just figured that some answers are to go to the bios settings but for me, I was able to resolve this by just disabling the hyper-v feature. We do this by following these steps:

window.location adds an item to your history in that you can (or should be able to) click "Back" and go back to the current page.

window.location.replace replaces the current history item so you can't go back to it.

See window.location:

assign(url): Load the document at the provided URL.

replace(url):Replace the current document with the one at the provided URL. The difference from the assign() method is that after using replace() the current page will not be saved in session history, meaning the user won't be able to use the Back button to navigate to it.

Oh and generally speaking:

window.location.href = url;

is favoured over:

window.location = url;

Use ng-disabled or a special CSS class with ng-class

<input data-ng-model="userInf.username"  
       class="span12 editEmail" 
       type="text"  
       placeholder="[email protected]"  
       pattern="[^@]+@[^@]+\.[a-zA-Z]{2,6}" 
       required 
       ng-disabled="{expression or condition}"
/>

The COLLATE keyword specify what kind of character set and rules (order, confrontation rules) you are using for string values.

For example in your case you are using Latin rules with case insensitive (CI) and accent sensitive (AS)

You can refer to this Documentation

In my case i had to hide submit button while users were selecting images.

This is what i come up:

$(document).on('click', '#image-field', function(e) {
  $('.submit-button').prop('disabled', true)
})
$(document).on('focus', '#image-field'), function(e) {
  $('.submit-button').prop('disabled', false)
})

#image-field is my file selector. When somenone clicks on it, i disable the form submit button. The point is, when the file dialog closed - doesn't matter they select a file or cancel - #image-field got the focus back, so i listen on that event.

UPDATE

I found that, this does not work in safari and poltergeist/phantomjs. Take this info into account if you would like to implement it.

For newer versions of Git there is git restore --staged <file>.

When I do a git status with Git version 2.26.2.windows.1 it is also recommended for unstaging:

Changes to be committed:
  (use "git restore --staged <file>..." to unstage)

(This post shows, that in earlier versions git reset HEAD was recommended at this point)

I can highly recommend this post explaining the differences between git revert, git restore and git reset and also additional parameters for git restore.

Thanks Szilagyi Donat for the answer. This one is taken from same and just where clause added.

I tried to to get these suggestions to work for a textblock, but couldn't get it to work. I even tried to get it to work from the designer. (Look in Layout and expand the list by clicking the down-arrow "V" at the bottom) I tried setting the scrollviewer to Visible and then Auto, but it still wouldn't work.

I eventually gave up and changed the TextBlock to a TextBox with the Readonly attribute set, and it worked like a charm.

This is how to create a jQuery live remove listener:

$(document).on('DOMNodeRemoved', function(e)
{
  var $element = $(e.target).find('.element');
  if ($element.length)

  }
});

Or:

$(document).on('DOMNodeRemoved', function(e)
{
  $(e.target).find('.element').each(function()
  {
    // do anything with $(this)
  }
});

You can get By Using this function.

I'm betting the problem is that Cygwin is writing Unix line endings (LF) to the file, and you're opening it with a program that expects Windows line-endings (CRLF). To determine if this is the case — and for a bit of a hackish workaround — try:

echo "`date` User `whoami` started the script."$'\r' >> output.log

(where the $'\r' at the end is an extra carriage-return; it, plus the Unix line ending, will result in a Windows line ending).

Super late to this thread but here goes.

TLDR; Add the following block in your AppDelegate.m

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{

 ....
    // HERE: replace "Verlag" with your font
  [[UILabel appearance] setFont:[UIFont fontWithName:@"Verlag" size:17.0]];
  ....
}

Walkthrough of the whole flow.

A few ways you can do this outside of using a plugin like react-native-global-props so Ill walk you though step by step.

Adding fonts to platforms.

How to add the font to IOS project

First let's create a location for our assets. Let's make the following directory at our root.

```

ios/
static/
       fonts/

```

Now let's add a "React Native" NPM in our package.json

  "rnpm": {
    "static": [
   "./static/fonts/"
    ]
  }

Now we can run "react-native link" to add our assets to our native apps.

Verifying or doing manually.

That should add your font names into the projects .plist (for VS code users run code ios/*/Info.plist to confirm)

Here let's assume Verlag is the font you added, it should look something like this:

     <dict>
   <plist>
      .....
      <key>UIAppFonts</key>
      <array>
         <string>Verlag Bold Italic.otf</string>
         <string>Verlag Book Italic.otf</string>
         <string>Verlag Light.otf</string>
         <string>Verlag XLight Italic.otf</string>
         <string>Verlag XLight.otf</string>
         <string>Verlag-Black.otf</string>
         <string>Verlag-BlackItalic.otf</string>
         <string>Verlag-Bold.otf</string>
         <string>Verlag-Book.otf</string>
         <string>Verlag-LightItalic.otf</string>
      </array>
      ....    
</dict>
</plist>

Now that you mapped them, now let's make sure they are actually there and being loaded (this is also how you'd do it manually).

Go to "Build Phase" > "Copy Bundler Resource", If it didn't work you'll a manually add under them here.

Get Font Names (recognized by XCode)

First open your XCode logs, like:

Then you can add the following block in your AppDelegate.m to log the names of the Fonts and the Font Family.

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    .....


  for (NSString* family in [UIFont familyNames])
  {
    NSLog(@"%@", family);
    for (NSString* name in [UIFont fontNamesForFamilyName: family])
    {
      NSLog(@" %@", name);
    }
  }

  ...
}

Once you run you should find your fonts if loaded correctly, here we found ours in logs like this:

2018-05-07 10:57:04.194127-0700 MyApp[84024:1486266] Verlag
2018-05-07 10:57:04.194266-0700 MyApp[84024:1486266]  Verlag-Book
2018-05-07 10:57:04.194401-0700 MyApp[84024:1486266]  Verlag-BlackItalic
2018-05-07 10:57:04.194516-0700 MyApp[84024:1486266]  Verlag-BoldItalic
2018-05-07 10:57:04.194616-0700 MyApp[84024:1486266]  Verlag-XLight
2018-05-07 10:57:04.194737-0700 MyApp[84024:1486266]  Verlag-Bold
2018-05-07 10:57:04.194833-0700 MyApp[84024:1486266]  Verlag-Black
2018-05-07 10:57:04.194942-0700 MyApp[84024:1486266]  Verlag-XLightItalic
2018-05-07 10:57:04.195170-0700 MyApp[84024:1486266]  Verlag-LightItalic
2018-05-07 10:57:04.195327-0700 MyApp[84024:1486266]  Verlag-BookItalic
2018-05-07 10:57:04.195510-0700 MyApp[84024:1486266]  Verlag-Light

So now we know it loaded the Verlag family and are the fonts inside that family

• Verlag-Book
• Verlag-BlackItalic
• Verlag-BoldItalic
• Verlag-XLight
• Verlag-Bold
• Verlag-Black
• Verlag-XLightItalic
• Verlag-LightItalic
• Verlag-BookItalic
• Verlag-Light

These are now the case sensitive names we can use in our font family we can use in our react native app.

Got -'em now set default font.

Then to set a default font to add your font family name in your AppDelegate.m with this line

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{

 ....
    // ADD THIS LINE (replace "Verlag" with your font)

  [[UILabel appearance] setFont:[UIFont fontWithName:@"Verlag" size:17.0]];
  ....
}

Done.

$STH - $DBH -> prepare( "select figure from table1" );

$STH -> execute();

$result = $STH ->fetch(PDO::FETCH_ASSOC)

echo $result["figure"];

$DBH = null;

There are multiple unlimited ways to refresh a page with JavaScript:

1. location.reload()
2. history.go(0)
3. location.href = location.href
4. location.href = location.pathname
5. location.replace(location.pathname)

6. location.reload(false)

   If we needed to pull the document from the web-server again (such as where the document contents change dynamically) we would pass the argument as true.

You can continue the list being creative:

• window.location = window.location
• window.self.window.self.window.window.location = window.location
• ...and other 534 ways

Use .unshift() to add to the beginning of an array.

TheArray.unshift(TheNewObject);

See MDN for doc on unshift() and here for doc on other array methods.

FYI, just like there's .push() and .pop() for the end of the array, there's .shift() and .unshift() for the beginning of the array.

I usually use BOOST_FOREACH:

#include <boost/foreach.hpp>

BOOST_FOREACH( vector_type::value_type& value, v ) {
    // do something with 'value'
}

It works on STL containers, arrays, C-style strings, etc.

I was having similar problem but I came out of the solution the problem was that you were using any thing in the dependency that correspond to same domain but with different versions make sure those all are same

A slight variation of the solutions already given here:

1. Create a local branch based on some other (remote or local) branch:

   git checkout -b branchname
   

2. Push the local branch to the remote repository (publish), but make it trackable so git pull and git push will work immediately

   git push -u origin HEAD
   

   Using HEAD is a "handy way to push the current branch to the same name on the remote". Source: https://git-scm.com/docs/git-push In Git terms, HEAD (in uppercase) is a reference to the top of the current branch (tree).

   The -u option is just short for --set-upstream. This will add an upstream tracking reference for the current branch. you can verify this by looking in your .git/config file:

   

In a browser

You can leverage the browser's URL parser using an <a> element:

var hostname = $('<a>').prop('href', url).prop('hostname');

or without jQuery:

var a = document.createElement('a');
a.href = url;
var hostname = a.hostname;

(This trick is particularly useful for resolving paths relative to the current page.)

Outside of a browser (and probably more efficiently):

Use the following function:

function get_hostname(url) {
    var m = url.match(/^http:\/\/[^/]+/);
    return m ? m[0] : null;
}

Use it like this:

get_hostname("http://example.com/path");

This will return http://example.com/ as in your example output.

Hostname of the current page

If you are only trying the get the hostname of the current page, use document.location.hostname.

I think your date comes from php and is written to html (dom) or? I have a php-function to prep all dates and timestamps. This return a formation that is be needed.

$timeForJS = timeop($datetimeFromDatabase['payedon'], 'js', 'local'); // save 10/12/2016 09:20 on var

this format can be used on js to create new Date...

<html>
   <span id="test" data-date="<?php echo $timeForJS; ?>"></span>
   <script>var myDate = new Date( $('#test').attr('data-date') );</script>
</html>

What i will say is, make your a own function to wrap, that make your life easyr. You can us my func as sample but is included in my cms you can not 1 to 1 copy and paste :)

    ], $output);

    return $output; // $output->getTimestamp();
}

Meanwhile, all the values above will only restrict the values to integer, so i use

/^[1-9][0-9\.]{0,15}$/

to allow float values too.

I had a similar issue with Spring Data MongoDB: I had to add the package path to @EnableMongoRepositories

Solution is very simple. Find *.module.ts files and comment declarations. In your case find addevent.module.ts file and remove/comment one line below:

@NgModule({
  declarations: [
    // AddEvent, <-- Comment or Remove This Line
  ],
  imports: [
    IonicPageModule.forChild(AddEvent),
  ],
})

This solution worked in ionic 3 for pages that generated by ionic-cli and works in both ionic serve and ionic cordova build android --prod --release commands!

Be happy...

If you're using Python3.x input will return a string,so you should use int method to convert string to integer.

Python3 Input

If the prompt argument is present, it is written to standard output without a trailing newline. The function then reads a line from input, converts it to a string (stripping a trailing newline), and returns that. When EOF is read, EOFError is raised.

By the way,it's a good way to use try catch if you want to convert string to int:

try:
  i = int(s)
except ValueError as err:
  pass 

Hope this helps.

$ which chromedriver
/usr/local/bin/chromedriver
$ chromedriver --version
ChromeDriver 78.0.3904.105

I downloaded a zip file from https://chromedriver.chromium.org/downloads It says "If you are using Chrome version 79, please download ChromeDriver 79.0.3945.36" and I was using Chrome version 79. (I checked chrome://settings/help) Apparently, the error for me was "This version of ChromeDriver only supports Chrome version 78"

And then I clicked the zip file and move that "chromedriver" file into /usr/local/bin/ directory. That solved the issue.

SELECT * 
FROM TABLE_NAME
WHERE Date_Column >= DATEADD(MONTH, -3, GETDATE()) 

Mureinik's suggested method will return the same results, but doing it this way your query can benefit from any indexes on Date_Column.

or you can check against last 90 days.

SELECT * 
FROM TABLE_NAME
WHERE Date_Column >= DATEADD(DAY, -90, GETDATE()) 

This is not an error, it is a warning from your Microsoft compiler.

Select your project and click "Properties" in the context menu.

In the dialog, chose Configuration Properties -> C/C++ -> Preprocessor

In the field PreprocessorDefinitions add ;_CRT_SECURE_NO_WARNINGS to turn those warnings off.

For SQL Server 2008, we can use information_schema.columns for getting column information

SELECT *

WHERE  table_name = 'Table_Name'
ORDER  BY ordinal_position  

With modern browsers, you can set the textContent property, see Node.textContent:

var span = document.getElementById("myspan");
span.textContent = "some text";

A BufferedReader can be opened and closed but a File is never opened, it just represents a path in the filesystem.

Use MethodInvoker for updating label text in other thread.

private void AggiornaContatore()
{
    MethodInvoker inv = delegate 
    {
      this.lblCounter.Text = this.index.ToString(); 
    }

 this.Invoke(inv);
}

You are getting the error because your UI thread is holding the label, and since you are trying to update it through another thread you are getting cross thread exception.

I feel that one of the mentioned cons for "Handlebars" isnt' really valid anymore.

Handlebars.java now allows us to share the same template languages for both client and server which is a big win for large projects with 1000+ components that require serverside rendering for SEO

Take a look at https://github.com/jknack/handlebars.java

As a beginner who stumbled across this thread, I'd like to add a python-for-dummies adaptation of abevieiramota's very neat answer (because I'm at the level that I had to look up 'ravel' to work out what their code was doing):

import numpy as np
import matplotlib.pyplot as plt

fig, ((ax1,ax2,ax3),(ax4,ax5,ax6)) = plt.subplots(2,3)

axlist = [ax1,ax2,ax3,ax4,ax5,ax6]

first = ax1.imshow(np.random.random((10,10)), vmin=0, vmax=1)
third = ax3.imshow(np.random.random((12,12)), vmin=0, vmax=1)

fig.colorbar(first, ax=axlist)

plt.show()

Much less pythonic, much easier for noobs like me to see what's actually happening here.

You can apply click on body of document and cancel click processing if the click event is generated by div with id menu_content, This will bind event to single element and saving binding of click with every element except menu_content

$('body').click(function(evt){    
       if(evt.target.id == "menu_content")
          return;
       //For descendants of menu_content being clicked, remove this check if you do not want to put constraint on descendants.
       if($(evt.target).closest('#menu_content').length)
          return;             

      //Do processing of click event here for every element except with id menu_content

});

Try changing it to.

I wrote this ES6 Class which does the Job.

class SvgToPngConverter {
  constructor() {
    this._init = this._init.bind(this);
    this._cleanUp = this._cleanUp.bind(this);
    this.convertFromInput = this.convertFromInput.bind(this);
  }

  _init() {
    this.canvas = document.createElement("canvas");
    this.imgPreview = document.createElement("img");
    this.imgPreview.style = "position: absolute; top: -9999px";

    document.body.appendChild(this.imgPreview);
    this.canvasCtx = this.canvas.getContext("2d");
  }

  _cleanUp() {
    document.body.removeChild(this.imgPreview);
  }

  convertFromInput(input, callback) {
    this._init();
    let _this = this;
    this.imgPreview.onload = function() {
      const img = new Image();
      _this.canvas.width = _this.imgPreview.clientWidth;
      _this.canvas.height = _this.imgPreview.clientHeight;
      img.crossOrigin = "anonymous";
      img.src = _this.imgPreview.src;
      img.onload = function() {
        _this.canvasCtx.drawImage(img, 0, 0);
        let imgData = _this.canvas.toDataURL("image/png");
        if(typeof callback == "function"){
            callback(imgData)
        }
        _this._cleanUp();
      };
    };

    this.imgPreview.src = input;
  }
}

Here is how you use it

let input = "https://restcountries.eu/data/afg.svg"
new SvgToPngConverter().convertFromInput(input, function(imgData){
    // You now have your png data in base64 (imgData). 
    // Do what ever you wish with it here.
});

If you want a vanilla JavaScript version, you could head over to Babel website and transpile the code there.

import re
result=[x for x in re.split(',| ',your_string) if x!='']

this works fine for me.

You can try group by on name and count the ids in that group.

If your driver is JDBC 4 compliant, there is no need for a dedicated query to test connections. Instead, there is Connection.isValid to test the connection.

JDBC 4 is part of Java 6 from 2006 and you driver should support this by now!

Famous connection pools, like HikariCP, still have a config parameter for specifying a test query but strongly discourage to use it:

connectionTestQuery

If your driver supports JDBC4 we strongly recommend not setting this property. This is for "legacy" databases that do not support the JDBC4 Connection.isValid() API. This is the query that will be executed just before a connection is given to you from the pool to validate that the connection to the database is still alive. Again, try running the pool without this property, HikariCP will log an error if your driver is not JDBC4 compliant to let you know. Default: none

one way manually

:set number
:10,12s/^/#

You really ought to get a framework in place via a repository and identifying your dependencies up front. Using the system scope is a common mistake people use, because they "don't care about the dependency management." The trouble is that doing this you end up with a perverted maven build that will not show maven in a normal condition. You would be better off following an approach like this.

Just for completeness (and this is not at all recommended):

int length;
try
{
   length = str.getBytes("UTF-16BE").length / 2
}
catch (UnsupportedEncodingException e)
{
   throw new AssertionError("Cannot happen: UTF-16BE is always a supported encoding");
}

This works because a char is a UTF-16 code unit, and str.length() returns the number of such code units. Each UTF-16 code unit takes up 2 bytes, so we divide by 2. Additionally, there is no byte order mark written with UTF-16BE.

I found a more straight forward solution from @DK comment in this question, the solution is written by Alex and described here with source, To make customized window:

1. download the sample project here
2. edit the generic.xaml file to customize the layout.
3. enjoy :).

The simplest way to get a list of only indexes is to use the answer above, with the 'h=index' parameter:

curl -XGET "localhost:9200/_cat/indices?h=index"

What are you doing: (I am using bytes instead of in for better reading)

You start with int *ap and so on, so your (your computers) memory looks like this:

-------------- memory used by some one else --------
000: ?
001: ?
...
098: ?
099: ?
-------------- your memory  --------
100: something          <- here is *ap
101: 41                 <- here starts a[] 
102: 42
103: 43
104: 44
105: 45
106: something          <- here waits x

lets take a look waht happens when (print short cut for ...print("$d", ...)

print a[0]  -> 41   //no surprise
print a     -> 101  // because a points to the start of the array
print *a    -> 41   // again the first element of array
print a+1   -> guess? 102
print *(a+1)    -> whats behind 102? 42 (we all love this number)

and so on, so a[0] is the same as *a, a[1] = *(a+1), ....

a[n] just reads easier.

now, what happens at line 9?

ap=a[4] // we know a[4]=*(a+4) somehow *105 ==>  45 
// warning! converting int to pointer!
-------------- your memory  --------
100: 45         <- here is *ap now 45

x = *ap;   // wow ap is 45 -> where is 45 pointing to?
-------------- memory used by some one else --------
bang!      // dont touch neighbours garden

So the "warning" is not just a warning it's a severe error.

I was running into this with a ServiceStack dll I had installed with nuget. Turns out there was another set of dlls available that were labeled signed. Not going to be the answer for everyone, but you may just need to check for an existing signed version of your assembly.

Here is one approach you can use which would work even if both dictonaries don't have same keys:

d1 = {'a':'test','b':'btest','d':'dreg'}
d2 = {'a':'cool','b':'main','c':'clear'}

d = {}

for key in set(d1.keys() + d2.keys()):
    try:
        d.setdefault(key,[]).append(d1[key])        
    except KeyError:
        pass

    try:
        d.setdefault(key,[]).append(d2[key])          
    except KeyError:
        pass

print d

This would generate below input:

{'a': ['test', 'cool'], 'c': ['clear'], 'b': ['btest', 'main'], 'd': ['dreg']}

You can get clean and clear solutions by building the appropriate predicates as helper functions. In other words, use the Python set-builder notation the same way you would write the answer with regular mathematics set-notation.

The whole idea behind set comprehensions is to let us write and reason in code the same way we do mathematics by hand.

With an appropriate predicate in hand, problem 1 simplifies to:

 low_primes = {x for x in range(1, 100) if is_prime(x)}

And problem 2 simplifies to:

 low_prime_pairs = {(x, x+2) for x in range(1,100,2) if is_prime(x) and is_prime(x+2)}

Note how this code is a direct translation of the problem specification, "A Prime Pair is a pair of consecutive odd numbers that are both prime."

P.S. I'm trying to give you the correct problem solving technique without actually giving away the answer to the homework problem.

Since you have a ::1 localhost line in your hosts file, it would seem that curl is attempting to use IPv6 to contact your local web server.

Since the web server is not listening on IPv6, the connection fails.

You could try to use the --ipv4 option to curl, which should force an IPv4 connection when both are available.

Simpler and a Standard solution to increment the number and to retain the dot at the end. Even if you get the css right, it will not work if your HTML is not correct. see below.

CSS

ol {
  counter-reset: item;
}
ol li {
  display: block;
}
ol li:before {
  content: counters(item, ". ") ". ";
  counter-increment: item;
}

SASS

ol {
    counter-reset: item;
    li {
        display: block;
        &:before {
            content: counters(item, ". ") ". ";
            counter-increment: item
        }
    }
}

HTML Parent Child

If you add the child make sure the it is under the parent li.

<!-- WRONG -->
<ol>
    <li>Parent 1</li> <!-- Parent is Individual. Not hugging -->
        <ol> 
            <li>Child</li>
        </ol>
    <li>Parent 2</li>
</ol>

<!-- RIGHT -->
<ol>
    <li>Parent 1 
        <ol> 
            <li>Child</li>
        </ol>
    </li> <!-- Parent is Hugging the child -->
    <li>Parent 2</li>
</ol>

if you don't even want to initialize ng-model to a static value and each value is DB driven, it can be done in the following way. Angular compares the evaluated value and populates the drop down.

Here below modelData.unitId is retrieved from DB and is compared to the list of unit id which is a separate list from db-

 <select id="uomList" ng-init="modelData.unitId"_x000D_
                         ng-model="modelData.unitId" ng-options="unitOfMeasurement.id as unitOfMeasurement.unitName for unitOfMeasurement in unitOfMeasurements">

@Taesung Shin is right, but then just some more magic to make it into a data.frame. I added a "x|y" line to avoid ambiguities:

df <- data.frame(ID=11:13, FOO=c('a|b','b|c','x|y'))
foo <- data.frame(do.call('rbind', strsplit(as.character(df$FOO),'|',fixed=TRUE)))

Or, if you want to replace the columns in the existing data.frame:

within(df, FOO<-data.frame(do.call('rbind', strsplit(as.character(FOO), '|', fixed=TRUE))))

Which produces:

  ID FOO.X1 FOO.X2
1 11      a      b
2 12      b      c
3 13      x      y

The easiest thing you can do is wrap the contents of the <li> in a <span> or equivalent then you can set the color independently.

Alternatively, you could make an image with the bullet color you want and set it with the list-style-image property.

You guys are completely right numbers can only go in the numeric field. I use the exact same thing as already listed with a bit of css styling on a span tag:

<span>$</span><input type="number" min="0.01" step="0.01" max="2500" value="25.67">

Then add a bit of styling magic:

span{
  position:relative;
  margin-right:-20px
}
input[type='number']{
  padding-left:20px;
  text-align:left;
}

The existence of that piece of metadata is entirely dependent on the application that wrote the file. It's very common to load up JPG files with metadata (EXIF tags) about the file, such as a timestamp or camera information or geolocation. ID3 tags in MP3 files are also very common. But it's a lot less common to see this kind of metadata in video files.

If you just need a tool to read this data from files manually, GSpot might do the trick: http://www.videohelp.com/tools/Gspot

If you want to read this in code then I imagine each container format is going to have its own standards and each one will take a bit of research and implementation to support.

Mongo includes a mongoexport utility (see docs) which can dump a collection. This utility uses the native libmongoclient and is likely the fastest method.

mongoexport -d <database> -c <collection_name>

Also helpful:

-o: write the output to file, otherwise standard output is used (docs)

--jsonArray: generates a valid json document, instead of one json object per line (docs)

--pretty: outputs formatted json (docs)

Regarding number of days in month just use static switch command and check if (year % 4 == 0) in which case February will have 29 days.

Minute, hour, day etc:

var someMillisecondValue = 511111222127;
var date = new Date(someMillisecondValue);
var minute = date.getMinutes();
var hour = date.getHours();
var day = date.getDate();
var month = date.getMonth();
var year = date.getFullYear();
alert([minute, hour, day, month, year].join("\n"));

date_default_timezone_set('Australia/Melbourne');   
$time = date("Y-m-d H:i:s", time()); 

As of 2016 you can also use the tidyverse.

library(tidyverse)
samp %>% remove_rownames %>% column_to_rownames(var="names")

Use json_encode($json_array, JSON_HEX_QUOT); since php 5.3: http://php.net/manual/en/json.constants.php

A web application's context path is the directory that contains the web application's WEB-INF directory. It can be thought of as the 'home' of the web app. Often, when writing web applications, it can be important to get the actual location of this directory in the file system, since this allows you to do things such as read from files or write to files.

This location can be obtained via the ServletContext object's getRealPath() method. This method can be passed a String parameter set to File.separator to get the path using the operating system's file separator ("/" for UNIX, "\" for Windows).

In my case a folder in my directory named as the git-repository on the server caused the failure.

You can try this:

-ms-transform: scale(width,height); /* IE 9 */
-webkit-transform: scale(width,height); /* Safari */
transform: scale(width, height);

Example: image "grows" 1.3 times

-ms-transform: scale(1.3,1.3); /* IE 9 */
-webkit-transform: scale(1.3,1.3); /* Safari */
transform: scale(1.3,1.3);

Looking at the dates for which it doesn't work -- those where the day is less than or equal to 12 -- I'm wondering whether it's parsing the dates as being in YYYY-DD-MM format?

One of the answers includes the background-size: contain css statement which I like a lot because it is straightforward statement of what you want to do and the browser just does it.

Unfortunately sooner or later you are going to need to apply a shadow which unfortunately will not play well with background image solutions.

So let's say that you have a container which is responsive but it has well defined boundaries for min and max width and height.

.photo {
  max-width: 150px;
  min-width: 75px;
  max-height: 150px;
  min-height: 75px;
}

And the container has an img which must be aware of the pixels of the height of the container in order to avoid getting a very high image which overflows or is cropped.

The img should also define a max-width of 100% in order first to allow smaller widths to be rendered and secondly to be percentage based which makes it parametric.

.photo > img {
  max-width: 100%;
  max-height: 150px;
  -webkit-box-shadow: 0 0 13px 3px rgba(0,0,0,1);
  -moz-box-shadow:    0 0 13px 3px rgba(0,0,0,1);
  box-shadow:         0 0 13px 3px rgba(0,0,0,1);
}

Note that it has a nice shadow ;)

I tried a few of the solutions from this thread. It seemed to work, but my values were always true and I also encountered the following issue: JENKINS-40235

I managed to use parameters in groovy jenkinsfile using the following syntax: params.myVariable

Here's a working example:

Solution

print 'DEBUG: parameter isFoo = ' + params.isFoo
print "DEBUG: parameter isFoo = ${params.isFoo}"

A more detailed (and working) example:

node() {
   // adds job parameters within jenkinsfile
   properties([
     parameters([
       booleanParam(
         defaultValue: false,
         description: 'isFoo should be false',
         name: 'isFoo'
       ),
       booleanParam(
         defaultValue: true,
         description: 'isBar should be true',
         name: 'isBar'
       ),
     ])
   ])

   // test the false value
   print 'DEBUG: parameter isFoo = ' + params.isFoo
   print "DEBUG: parameter isFoo = ${params.isFoo}"
   sh "echo sh isFoo is ${params.isFoo}"
   if (params.isFoo) { print "THIS SHOULD NOT DISPLAY" }

   // test the true value
   print 'DEBUG: parameter isBar = ' + params.isBar
   print "DEBUG: parameter isBar = ${params.isBar}"
   sh "echo sh isBar is ${params.isBar}"
   if (params.isBar) { print "this should display" }
}

Output

I sent a Pull Request to update the misleading pipeline tutorial#build-parameters quote that says "they are accessible as Groovy variables of the same name.". ;)

Edit: As Jesse Glick pointed out: Release notes go into more details

You should also update the Pipeline Job Plugin to 2.7 or later, so that build parameters are defined as environment variables and thus accessible as if they were global Groovy variables.

Sometimes the columns will have commas within themselves, such as:

"Some item", "Another Item", "Also, One more item"

In these cases, splitting on "," will break some columns. Maybe an easier way, but I just made my own method (as a bonus, handles spaces after commas and returns an IList):

private IList<string> GetColumns(string columns)
{
    IList<string> list = new List<string>();

    if (!string.IsNullOrWhiteSpace(columns))
    {
        if (columns[0] != '\"')
        {
            // treat as just one item
            list.Add(columns);
        }
        else
        {
            bool gettingItemName = true;
            bool justChanged = false;
            string itemName = string.Empty;

            for (int index = 1; index < columns.Length; index++)
            {
                justChanged = false;
                if (subIndustries[index] == '\"')
                {
                    gettingItemName = !gettingItemName;
                    justChanged = true;
                }

                if ((gettingItemName == false) &&
                (justChanged == true))
                {
                    list.Add(itemName);
                    itemName = string.Empty;
                    justChanged = false;
                }

                if ((gettingItemName == true) && (justChanged == false))
                {
                    itemName += columns[index];
                }
            }
        }
    }

    return list;
}

I have also got stuck into this and believe me disabling SELinux is not a good idea.

Please just use below and you are good,

sudo restorecon -R /var/www/mysite

delete from employee where rowid in (select rowid from (select rowid, name_count from (select rowid, count(emp_name) as name_count from employee group by emp_id, emp_name) where name_count>1))

Make sure that Windows Authentication hasn't been disabled for the Website / Application within IIS.

I'm not sure HOW this happened, but I did uninstall Hyper-V today to be able to install VMWare Player and then re-install Hyper-V

Reenabling this allowed everything to work again.

I disagree that .form-group should be within .col-*-n elements. In my experience, all the appropriate padding happens automatically when you use .form-group like .row within a form.

<div class="form-group">
    <div class="col-sm-12">
        <label for="user_login">Username</label>
        <input class="form-control" id="user_login" name="user[login]" required="true" size="30" type="text" />
    </div>
</div>

Check out this demo.

Altering the demo slightly by adding .form-horizontal to the form tag changes some of that padding.

<form action="#" method="post" class="form-horizontal">

Check out this demo.

When in doubt, inspect in Chrome or use Firebug in Firefox to figure out things like padding and margins. Using .row within the form fails in edsioufi's fiddle because .row uses negative left and right margins thereby drawing the horizontal bounds of the divs classed .row beyond the bounds of the containing fieldsets.

It's too late to answer this question now, but hope this helps someone.

@Eimantas has already given the best answer but the solution won't work if you have two or more tables by the same name under the same server.

I have slightly modified @Eimantas's answer to tackle the above problem.

select Auto_increment as id from information_schema.tables where table_name = 'table_name' and table_schema = 'database_name'

Found the solution!

I had something similar:

It took a while to figure this out. Have tried:

1. Reinstalling the whole VS2019 web development environment
2. Deleting `%userprofile%\Documents\IISExpress`
3. Deleting projects' `.vs` folders
4. Removing `IIExpress 10` from `Programms` in Win10
5. Changing projects' settings/properties

The main problem was a registry entry Start located at

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\HTTP

So, changing value of a key Start from 4 to 3 and rebooting fixed the issue.

One of possible reason I would recall is running the Laragon which required changing this value to 4 to start an Nginx web server.

There's no need to use jQuery to change the title. Try:

document.title = "blarg";

See this question for more details.

To dynamically change on button click:

$(selectorForMyButton).click(function(){
    document.title = "blarg";
});

To dynamically change in loop, try:

var counter = 0;

var titleTimerId = setInterval(function(){
    document.title = document.title + '>';
    counter++;
    if(counter == 5){
        clearInterval(titleTimerId);
    }
}, 100);

To string the two together so that it dynamically changes on button click, in a loop:

var counter = 0;

$(selectorForMyButton).click(function(){
  titleTimerId = setInterval(function(){
    document.title = document.title + '>';
    counter++;
    if(counter == 5){
        clearInterval(titleTimerId);
    }
  }, 100);
});

datetime.datetime.fromtimestamp() is correct, except you are probably having timestamp in miliseconds (like in JavaScript), but fromtimestamp() expects Unix timestamp, in seconds.

Do it like that:

>>> import datetime
>>> your_timestamp = 1331856000000
>>> date = datetime.datetime.fromtimestamp(your_timestamp / 1e3)

and the result is:

>>> date
datetime.datetime(2012, 3, 16, 1, 0)

Does it answer your question?

EDIT: J.F. Sebastian correctly suggested to use true division by 1e3 (float 1000). The difference is significant, if you would like to get precise results, thus I changed my answer. The difference results from the default behaviour of Python 2.x, which always returns int when dividing (using / operator) int by int (this is called floor division). By replacing the divisor 1000 (being an int) with the 1e3 divisor (being representation of 1000 as float) or with float(1000) (or 1000. etc.), the division becomes true division. Python 2.x returns float when dividing int by float, float by int, float by float etc. And when there is some fractional part in the timestamp passed to fromtimestamp() method, this method's result also contains information about that fractional part (as the number of microseconds).

The DECLARE GLOBAL TEMPORARY TABLE statement defines a temporary table for the current connection.

These tables do not reside in the system catalogs and are not persistent.

Temporary tables exist only during the connection that declared them and cannot be referenced outside of that connection.

When the connection closes, the rows of the table are deleted, and the in-memory description of the temporary table is dropped.

For your reference http://docs.oracle.com/javadb/10.6.2.1/ref/rrefdeclaretemptable.html

I also had the same problem and able to resolve after using below command

/root/mysql-sandboxes/3320/bin/mysqld --defaults-file=/root/mysql-sandboxes/3320/my.cnf  --user=root &

It's your "fault" in that that's how Or is defined, so it's the behaviour you should expect:

In a Boolean comparison, the Or operator always evaluates both expressions, which could include making procedure calls. The OrElse Operator (Visual Basic) performs short-circuiting, which means that if expression1 is True, then expression2 is not evaluated.

But you don't have to endure it. You can use OrElse to get short-circuiting behaviour.

So you probably want:

If (example Is Nothing OrElse Not example.Item = compare.Item) Then
    'Proceed
End If

I can't say it reads terribly nicely, but it should work...

Create an init() function and point the table layout. Then create the needed rows and columns.

   public void init() {
            TableLayout stk = (TableLayout) findViewById(R.id.table_main);
            TableRow tbrow0 = new TableRow(this);
            TextView tv0 = new TextView(this);
            tv0.setText(" Sl.No ");
            tv0.setTextColor(Color.WHITE);
            tbrow0.addView(tv0);
            TextView tv1 = new TextView(this);
            tv1.setText(" Product ");
            tv1.setTextColor(Color.WHITE);
            tbrow0.addView(tv1);
            TextView tv2 = new TextView(this);
            tv2.setText(" Unit Price ");
            tv2.setTextColor(Color.WHITE);
            tbrow0.addView(tv2);
            TextView tv3 = new TextView(this);
            tv3.setText(" Stock Remaining ");
            tv3.setTextColor(Color.WHITE);
            tbrow0.addView(tv3);
            stk.addView(tbrow0);
            for (int i = 0; i < 25; i++) {
                TableRow tbrow = new TableRow(this);
                TextView t1v = new TextView(this);
                t1v.setText("" + i);
                t1v.setTextColor(Color.WHITE);
                t1v.setGravity(Gravity.CENTER);
                tbrow.addView(t1v);
                TextView t2v = new TextView(this);
                t2v.setText("Product " + i);
                t2v.setTextColor(Color.WHITE);
                t2v.setGravity(Gravity.CENTER);
                tbrow.addView(t2v);
                TextView t3v = new TextView(this);
                t3v.setText("Rs." + i);
                t3v.setTextColor(Color.WHITE);
                t3v.setGravity(Gravity.CENTER);
                tbrow.addView(t3v);
                TextView t4v = new TextView(this);
                t4v.setText("" + i * 15 / 32 * 10);
                t4v.setTextColor(Color.WHITE);
                t4v.setGravity(Gravity.CENTER);
                tbrow.addView(t4v);
                stk.addView(tbrow);
            }

        }

Call init function in your onCreate method:

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.activity_main);

        init();
    }

Layout file like:

 <ScrollView
        android:id="@+id/scrollView1"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:background="#3d455b"
        android:layout_alignParentLeft="true" >

        <HorizontalScrollView
            android:id="@+id/hscrll1"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content" >

            <RelativeLayout
                android:id="@+id/RelativeLayout1"
                android:layout_width="fill_parent"
                android:layout_gravity="center"
                android:layout_height="fill_parent"
                android:orientation="vertical" >

                <TableLayout
                    android:id="@+id/table_main"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:layout_centerHorizontal="true" >
                </TableLayout>
            </RelativeLayout>
        </HorizontalScrollView>
    </ScrollView>

Will look like:

You can simply define the key to use directly when running the command:

ansible-playbook \
        \ # Super verbose output incl. SSH-Details:
    -vvvv \
        \ # The Server to target: (Keep the trailing comma!)
    -i "000.000.0.000," \
        \ # Define the key to use:
    --private-key=~/.ssh/id_rsa_ansible \
        \ # The `env` var is needed if `python` is not available:
    -e 'ansible_python_interpreter=/usr/bin/python3' \ # Needed if `python` is not available
        \ # Dry–Run:
    --check \
    deploy.yml

Copy/ Paste:

ansible-playbook -vvvv --private-key=/Users/you/.ssh/your_key deploy.yml
