Programs & Examples On #Clonenode

When I try:

<input type="button" id="moreFields" onclick="alert('The text will be show!!'); return false;" value="Give me more fields!"  />

It's worked well. So I think the problem is position of moreFields() function. Ensure that function will be define before your input tag.

Pls try:

<script type="text/javascript">
    function moreFields() {
        alert("The text will be show");
    }
</script>

<input type="button" id="moreFields" onclick="moreFields()" value="Give me more fields!"  />

Hope it helped.

For a project this size, you should stop writing pure JavaScript and turn to some of the libraries available. I'd recommend jQuery (http://jquery.com/), which allows you to select elements by css-selectors, which I recon should speed up your development quite a bit.

Example of your code then becomes;

function AddtoCart() {
  var len = $("#Items tr").length, $row, $inp1, $inp2, $cells;

  $row = $("#Items td:first").clone(true);
  $cells = $row.find("td");

  $cells.get(0).html( len );

  $inp1 = $cells.get(1).find("input:first");
  $inp1.attr("id", $inp1.attr("id") + len).val("");

  $inp2 = $cells.get(2).find("input:first");
  $inp2.attr("id", $inp2.attr("id") + len).val("");

  $("#Items").append($row);
    }

I can see that you might not understand that code yet, but take a look at jQuery, it's easy to learn and will make this development way faster.

I would use the libraries already created specifically for js shopping carts if I were you though.

To your problem; If i look at your jsFiddle, it doesn't even seem like you have defined a table with the id Items? Maybe that's why it doesn't work?

Using jQuery you can do this:

var str = '<td>1</td><td>2</td>';
$('#__TABLE__').replaceWith(str);

http://jsfiddle.net/hZBeW/4/

Or in pure javascript:

var str = '<td>1</td><td>2</td>';
var tdElement = document.getElementById('__TABLE__');
var trElement = tdElement.parentNode;
trElement.removeChild(tdElement);
trElement.innerHTML = str + trElement.innerHTML;

Reset form validation after adding new fields.

function resetFormValidator(formId) {
    $(formId).removeData('validator');
    $(formId).removeData('unobtrusiveValidation');
    $.validator.unobtrusive.parse(formId);
}

Lo-Dash, now a superset of Underscore.js, has a couple of deep clone functions:

• _.cloneDeep(object)

• _.cloneDeepWith(object, (val) => {if(_.isElement(val)) return val.cloneNode(true)})

  the second parameter is a function that is invoked to produce the cloned value.

From an answer of the author himself:

lodash underscore build is provided to ensure compatibility with the latest stable version of Underscore.

mysqladmin -u [username] -p password worked for me on OS X El Capitan and MySQL 5.7.12 Community Server. Example:

$ /usr/local/mysql/bin/mysqladmin -u root -p password
Enter password:
New password:
Confirm new password:
Warning: Since password will be sent to server in plain text, use ssl connection to ensure password safety.

This is similar to pavan sachi's answer, but with password prompts.

My error was "#1862 - Your password has expired. To log in you must change it using a client that supports expired passwords." at phpMyAdmin login screen first time.

To send a message through TLS/SSL, you need to set Ssl of the SmtpClient class to true.

string to = "[email protected]";
string from = "[email protected]";
MailMessage message = new MailMessage(from, to);
message.Subject = "Using the new SMTP client.";
message.Body = @"Using this new feature, you can send an e-mail message from an application very easily.";
SmtpClient client = new SmtpClient(server);
// Credentials are necessary if the server requires the client 
// to authenticate before it will send e-mail on the client's behalf.
client.UseDefaultCredentials = true;
client.EnableSsl = true;
client.Send(message);

You can make the pagebreak conditional on knitting to PDF. This worked for me.

```{r, results='asis', eval=(opts_knit$get('rmarkdown.pandoc.to') == 'latex')}
cat('\\pagebreak')
```

Actually the list of parameters could be accessed with $1 $2 ... etc.
Which is exactly equivalent to:

${!i}

So, the list of parameters could be changed with set,
and ${!i} is the correct way to access them:

$ set -- aa bb cc dd 55 ff gg hh ii jjj kkk lll
$ for ((i=0;i<=$#;i++)); do echo "$#" "$i" "${!i}"; done

12 1 aa
12 2 bb
12 3 cc
12 4 dd
12 5 55
12 6 ff
12 7 gg
12 8 hh
12 9 ii
12 10 jjj
12 11 kkk
12 12 lll

For your specific case, this could be used (without the need for arrays), to set the list of arguments when none was given:

if [ "$#" -eq 0 ]; then
    set -- defaultarg1 defaultarg2
fi

which translates to this even simpler expression:

[ "$#" == "0" ] && set -- defaultarg1 defaultarg2

var d = new Date();
var month = d.getMonth() + 1;
var day = d.getDate();
var year = d.getYear();
var today = (day<10?'0':'')+ day + '/' +(month<10?'0':'')+ month + '/' + year;
alert(today);

Neither clean/reset/hard checkout/rebase worked for me.

So I just removed files that git complained about*

rm /path/to/files/that/git/complained/about

*I checked if this files can be removed by checking out a brand new repo in a separate folder (files were not there)

You can do it if you wrap your text into a span like:

a {_x000D_
  color: red;_x000D_
  text-decoration: underline;_x000D_
}_x000D_
span {_x000D_
  color: blue;_x000D_
  text-decoration: none;_x000D_
}

<a href="#">_x000D_
  <span>Text</span>_x000D_
</a>

Another possible solution with JS

function onSelect(e) {
    if (e.files.length > 5) {
        alert("Only 5 files accepted.");
        e.preventDefault();
    }
}

<script type="text/javascript">
var uri = window.location.toString();
if (uri.indexOf("?") > 0) {
    var clean_uri = uri.substring(0, uri.indexOf("?"));
    window.history.replaceState({}, document.title, clean_uri);
}
</script>

put this code on head section

I prefer to do it in code:

// Run a specific test only
//testing::GTEST_FLAG(filter) = "MyLibrary.TestReading"; // I'm testing a new feature, run something quickly

// Exclude a specific test
testing::GTEST_FLAG(filter) = "-MyLibrary.TestWriting"; // The writing test is broken, so skip it

I can either comment out both lines to run all tests, uncomment out the first line to test a single feature that I'm investigating/working on, or uncomment the second line if a test is broken but I want to test everything else.
You can also test/exclude a suite of features by using wildcards and writing a list, "MyLibrary.TestNetwork*" or "-MyLibrary.TestFileSystem*".

Table name change

RENAME TABLE old_table_name TO new_table_name;

Visual Studio provides lots of options for conditional breakpoints:

To set any of these you

1. Set a breakpoint.
2. Right-Click over the breakpoint, and in the popup menu you select an option that suites you.

These options are as follows:

• You can set a condition, based on a code expression that you supply (select Condition from the popup menu). For instance, you can specify that foo == 8 or some other expression.
• You can make breakpoints trigger after they have been hit a certain number of times. (select Hit Count from the popup menu). This is a fun option to play with as you actually aren't limited to breaking on a certain hit count, but you have options for a few other scenarios as well. I'll leave it to you to explore the possibilities.
• You can Set filters on the Process ID, thread ID, and machine name (select Filter from the popup menu)

Take a look at ?legend and try this:

legend('topright', names(a)[-1] , 
   lty=1, col=c('red', 'blue', 'green',' brown'), bty='n', cex=.75)

It should be quite simple if you are using LogBack or SLF4J. I do it as below

//imports
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

//Initialize logger
Logger logger = LoggerFactory.getLogger(<classname>.class);
try {
   //try something
} catch(Exception e){
   //Actual logging of error
   logger.error("some message", e);
}

Maybe this helps someone: You can always place the div outside the other div and then push it upwards using negative margin:

<div id="container" style="background-color: #ccc; padding-bottom: 30px;">
  Hello!
</div>
<div id="copyright" style="margin-top: -20px;">
  Copyright Foo web designs
</div>

AFAIK, you can't create a File from an assets file because these are stored in the apk, that means there is no path to an assets folder.

But, you can try to create that File using a buffer and the AssetManager (it provides access to an application's raw asset files).

Try to do something like:

AssetManager am = getAssets();
InputStream inputStream = am.open("myfoldername/myfilename");
File file = createFileFromInputStream(inputStream);

private File createFileFromInputStream(InputStream inputStream) {

   try{
      File f = new File(my_file_name);
      OutputStream outputStream = new FileOutputStream(f);
      byte buffer[] = new byte[1024];
      int length = 0;

      while((length=inputStream.read(buffer)) > 0) {
        outputStream.write(buffer,0,length);
      }

      outputStream.close();
      inputStream.close();

      return f;
   }catch (IOException e) {
         //Logging exception
   }

   return null;
}

Let me know about your progress.

Since version 3.3 of ggplot2, we have access to the convenient after_stat() function.

We can do something similar to @Andrew's answer, but without using the .. syntax:

# original example data
mydata <- c("aa", "bb", NULL, "bb", "cc", "aa", "aa", "aa", "ee", NULL, "cc")

# display percentages
library(ggplot2)
ggplot(mapping = aes(x = mydata,
                     y = after_stat(count/sum(count)))) +
  geom_bar() +
  scale_y_continuous(labels = scales::percent)

You can find all the "computed variables" available to use in the documentation of the geom_ and stat_ functions. For example, for geom_bar(), you can access the count and prop variables. (See the documentation for computed variables.)

One comment about your NULL values: they are ignored when you create the vector (i.e. you end up with a vector of length 9, not 11). If you really want to keep track of missing data, you will have to use NA instead (ggplot2 will put NAs at the right end of the plot):

# use NA instead of NULL
mydata <- c("aa", "bb", NA, "bb", "cc", "aa", "aa", "aa", "ee", NA, "cc")
length(mydata)
#> [1] 11

# display percentages
library(ggplot2)
ggplot(mapping = aes(x = mydata,
                     y = after_stat(count/sum(count)))) +
  geom_bar() +
  scale_y_continuous(labels = scales::percent)

^{Created on 2021-02-09 by the reprex package (v1.0.0)}

(Note that using chr or fct data will not make a difference for your example.)

just add a variable in CSHTML file var myVariable = @"@";

and add it to your layout <span class="my-class"><a href="@myVariale" target="_blank" >link text</a></span>

You probably forgot to set the form's KeyPreview property to True. Overriding the ProcessCmdKey() method is the generic solution:

protected override bool ProcessCmdKey(ref Message msg, Keys keyData) {
  if (keyData == (Keys.Control | Keys.F)) {
    MessageBox.Show("What the Ctrl+F?");
    return true;
  }
  return base.ProcessCmdKey(ref msg, keyData);
}

With dplyr 0.7.2, you can use the very useful case_when function :

x=read.table(
 text="V1 V2 V3 V4
 1  1  2  3  5
 2  2  4  4  1
 3  1  4  1  1
 4  4  5  1  3
 5  5  5  5  4")
x$V5 = case_when(x$V1==1 & x$V2!=4 ~ 1,
                 x$V2==4 & x$V3!=1 ~ 2,
                 TRUE ~ 0)

Expressed with dplyr::mutate, it gives:

x = x %>% mutate(
     V5 = case_when(
         V1==1 & V2!=4 ~ 1,
         V2==4 & V3!=1 ~ 2,
         TRUE ~ 0
     )
)

Please note that NA are not treated specially, as it can be misleading. The function will return NA only when no condition is matched. If you put a line with TRUE ~ ..., like I did in my example, the return value will then never be NA.

Therefore, you have to expressively tell case_when to put NA where it belongs by adding a statement like is.na(x$V1) | is.na(x$V3) ~ NA_integer_. Hint: the dplyr::coalesce() function can be really useful here sometimes!

Moreover, please note that NA alone will usually not work, you have to put special NA values : NA_integer_, NA_character_ or NA_real_.

on windows: Go to "Add or remove programs" in control panel (or open the start menu and search for "remove program")

You can also just enter the website and:

1. Choose a repository you have write access to (example URL)
2. Click "Upload files"
3. Drag and drop a folder with files into the "Drag files here to add them to your repository" area.

The same limitation applies here: the folder must contain at least one file inside it.

If you run into this in Xcode 10 you will have to clean before build. Or, switch to the legacy build system. File -> Workspace Settings... -> Build System: Legacy Build System.

I think you are putting one too many curly brackets. Try this

 @if($user->status=='waiting')
            <td><a href="#" class="viewPopLink btn btn-default1" role="button" data-id="{!! $user->travel_id !!}" data-toggle="modal" data-target="#myModal">Approve/Reject</a> </td>
            @else
            <td>{!! $user->status !!}</td>
        @endif

This worked for me

yum install mysql

It will install mysql client and then

pip install mysqlclient

In my case, I had a very similar problem. I was updating my view inside a function that was being called by a parent component, and in my parent component I forgot to use @ViewChild(NameOfMyChieldComponent). I lost at least 3 hours just for this stupid mistake. i.e: I didn't need to use any of those methods:

• ChangeDetectorRef.detectChanges()
• ChangeDetectorRef.markForCheck()
• ApplicationRef.tick()

Please remove call to trustSrc function and try again like this . {{trustSrc(currentProject.url)}} to {{currentProject.url}}. Check this link http://plnkr.co/edit/caqS1jE9fpmMn5NofUve?p=preview

Before:

Javascript

scope.baseUrl = 'page';
scope.a = 1;
scope.b = 2;

Html

<!-- Are a and b properly escaped here? Is baseUrl controlled by user? -->
<iframe src="{{baseUrl}}?a={{a}&b={{b}}"

But for security reason they are recommending following method

Javascript

var baseUrl = "page";
scope.getIframeSrc = function() {

  // One should think about their particular case and sanitize accordingly
  var qs = ["a", "b"].map(function(value, name) {
      return encodeURIComponent(name) + "=" +
             encodeURIComponent(value);
    }).join("&");

  // `baseUrl` isn't exposed to a user's control, so we don't have to worry about escaping it.
  return baseUrl + "?" + qs;
};

Html

<iframe src="{{getIframeSrc()}}">

because of your a and b variable is not have been initialized. You must initialized this variables for excample if you declare this variable like this int a=0; int b=0; than your code run without error.

Make sure you add both Jackson jars to classpath:

• jackson-core-asl-x.jar
• jackson-mapper-asl-x.jar

Also, you must have the following in your Spring xml file:

<mvc:annotation-driven />

What is the other application you are trying to suppress the visibility of? Have you investigated other ways of achieving your desired effect? Please do so before subjecting your users to such rogue behaviour as you are describing: what you are trying to do sound rather like what certain naughty sites do with browser windows...

At least try to adhere to the rule of Least Surprise. Users expect to be able to determine the z-order of most applications themselves. You don't know what is most important to them, so if you change anything, you should focus on pushing the other application behind everything rather than promoting your own.

This is of course trickier, since Windows doesn't have a particularly sophisticated window manager. Two approaches suggest themselves:

1. enumerating top-level windows and checking which process they belong to, dropping their z-order if so. (I'm not sure if there are framework methods for these WinAPI functions.)
2. Fiddling with child process permissions to prevent it from accessing the desktop... but I wouldn't try this until the othe approach failed, as the child process might end up in a zombie state while requiring user interaction.

For Wamp 3.1.3 and Apache 2.4 I simply had to change 1 line in my httpd-vhosts.conf file.

1. Open httpd-vhosts.conf
2. Change "Require local" to "Require all granted"
3. Restart all services

I was then able to get to my apache server from other computers.

I've seen a couple cases where this error occurs:

1. using the not equals operator != in a where clause with a list of multiple or values

such as:

where columnName !=('A'||'B')

This can be resolved by using

where columnName not in ('A','B')

2. missing a comparison operator in an if() function:

select if(col1,col1,col2);

in order to select the value in col1 if it exists and otherwise show the value in col2...this throws the error; it can be resolved by using:

select if(col1!='',col1,col2);

Also a good script, although my laptop ran out of memory, but this was on a very large table

I had this problem: My Web API 2 project on .NET 4.7.2 was working as expected, then I changed the project properties to use a Specific Page path under the Web tab. When I ran it every time since, it was giving me a 404 error - it didn't even hit the controller.

Solution: I found the .vs hidden folder in my parent directory of my VS solution file (sometimes the same directory), and deleted it. When I opened my VS solution once more, cleaned it, and rebuilt it with the Rebuild option, it ran again. There was a problem with the cached files created by Visual Studio. When these were deleted, and the solution was rebuilt, the files were recreated.

FROM openjdk:8-jdk-alpine RUN apk update && apk add wget openssl lsof procps curl RUN apk update RUN mkdir -p /apps/agent RUN mkdir -p /apps/lib ADD ./app/agent /apps/agent ADD ./app/lib /apps/lib ADD ./app/* /apps/app/ RUN ls -lrt /apps/app/ CMD sh /apps/app/launch.sh

by using DockerFile, I'm copying agent and lib directories to /apps/agent,/apps/lib directories and bunch of files to target.

You could achieve that simply by wrapping the image by a <div> and adding overflow: hidden to that element:

<div class="img-wrapper">
    <img src="..." />
</div>

.img-wrapper {
    display: inline-block; /* change the default display type to inline-block */
    overflow: hidden;      /* hide the overflow */
}

WORKING DEMO.

Also it's worth noting that <img> element (like the other inline elements) sits on its baseline by default. And there would be a 4~5px gap at the bottom of the image.

That vertical gap belongs to the reserved space of descenders like: g j p q y. You could fix the alignment issue by adding vertical-align property to the image with a value other than baseline.

Additionally for a better user experience, you could add transition to the images.

Thus we'll end up with the following:

.img-wrapper img {
    transition: all .2s ease;
    vertical-align: middle;
}

UPDATED DEMO.

If you want a pair (not supposedly key-value pair) just to hold two generic data together neither of the solutions above really handy since first (or so called Key) cannot be changed (neither in Apache Commons Lang's Pair nor in AbstractMap.SimpleEntry). They have thier own reasons, but still you may need to be able to change both of the components. Here is a Pair class in which both elements can be set

public class Pair<First, Second> {
    private First first;
    private Second second;

    public Pair(First first, Second second) {
        this.first = first;
        this.second = second;
    }

    public void setFirst(First first) {
        this.first = first;
    }

    public void setSecond(Second second) {
        this.second = second;
    }

    public First getFirst() {
        return first;
    }

    public Second getSecond() {
        return second;
    }

    public void set(First first, Second second) {
        setFirst(first);
        setSecond(second);
    }

    @Override
    public boolean equals(Object o) {
        if (this == o) return true;
        if (o == null || getClass() != o.getClass()) return false;

        Pair pair = (Pair) o;

        if (first != null ? !first.equals(pair.first) : pair.first != null) return false;
        if (second != null ? !second.equals(pair.second) : pair.second != null) return false;

        return true;
    }

    @Override
    public int hashCode() {
        int result = first != null ? first.hashCode() : 0;
        result = 31 * result + (second != null ? second.hashCode() : 0);
        return result;
    }
}

To get the "today" value in SQL:

convert(date, GETDATE())

To get "yesterday":

DATEADD(day, -1, convert(date, GETDATE()))

To get "today minus X days": change the -1 into -X.

So for all yesterday's rows, you get:

select * from tablename
   where date >= DATEADD(day, -1, convert(date, GETDATE()))
   and date < convert(date, GETDATE())

If you are using Python2.5 or older try

Solution is very simple.

1 Add Internet permission in Androidmanifest.xml file

<uses-permission android:name="android.permission.INTERNET" />

[2] Change your httpd.config file

Order Deny,Allow
Deny from all
Allow from 127.0.0.1

TO

Order Deny,Allow
Allow from all
Allow from 127.0.0.1

And restart your server.

[3] And most impotent step. MAKE YOUR NETWORK AS YOUR HOME NETWORK

Go to Control Panel > Network and Internet > Network and Sharing Center

Click on your Network and select HOME NETWORK

document.getElementById("placehere").appendChild(elem);

not

document.getElementById("placehere").appendChild("elem");

and use the below to set the source

elem.src = 'images/hydrangeas.jpg';

I have just tried to install that extension on my dev server.

First, make sure that the extension is correctly enabled. Your phpinfo() output doesn't seem complete.

If it is indeed installed properly, your phpinfo() should have a section that looks like this:

If you do not get that section in your phpinfo(). Make sure that you are using the right version. There are both non-thread-safe and thread-safe versions of the extension.

Finally, check your extension_dir setting. By default it's this: extension_dir = "ext", for most of the time it works fine, but if it doesn't try: extension_dir = "C:\PHP\ext".

===========================================================================

EDIT given new info:

You are using the wrong function. mssql_connect() is part of the Mssql extension. You are using microsoft's extension, so use sqlsrv_connect(), for the API for the microsoft driver, look at SQLSRV_Help.chm which should be extracted to your ext directory when you extracted the extension.

This is what worked best for me:

string parentOfStartupPath = Path.GetFullPath(Path.Combine(Application.StartupPath, @"../"));

Getting the 'right' path wasn't the problem, adding '../' obviously does that, but after that, the given string isn't usable, because it will just add the '../' at the end. Surrounding it with Path.GetFullPath() will give you the absolute path, making it usable.

Why not the following?

//How to check if a string begins with another string
$haystack = "valuehaystack";
$needle = "value";
if (strpos($haystack, $needle) === 0){
    echo "Found " . $needle . " at the beginning of " . $haystack . "!";
}

Output:

Found value at the beginning of valuehaystack!

Keep in mind, strpos will return false if the needle was not found in the haystack, and will return 0 if, and only if, needle was found at index 0 (AKA the beginning).

And here's endsWith:

$haystack = "valuehaystack";
$needle = "haystack";

//If index of the needle plus the length of the needle is the same length as the entire haystack.
if (strpos($haystack, $needle) + strlen($needle) === strlen($haystack)){
    echo "Found " . $needle . " at the end of " . $haystack . "!";
}

In this scenario there is no need for a function startsWith() as

(strpos($stringToSearch, $doesItStartWithThis) === 0)

will return true or false accurately.

It seems odd it's this simple with all the wild functions running rampant here.

Datetime is a datatype.

Timestamp is a method for row versioning. In fact, in sql server 2008 this column type was renamed (i.e. timestamp is deprecated) to rowversion. It basically means that every time a row is changed, this value is increased. This is done with a database counter which automatically increase for every inserted or updated row.

For more information:

This works for me! be careful with the new java versions because they cause error, check that you have everything installed and in your specific directory,

I did not use openJDK

export JAVA_HOME="/usr/lib/jvm/java-8-jdk" \
&& export PATH=$JAVA_HOME/bin:$PATH \
&& export ANDROID_HOME=$HOME/Android/Sdk \
&& export PATH=${PATH}:${ANDROID_HOME}/tools \

While this only works for scalar arrays (see note below), it is short:

array1.length === array2.length && array1.every(function(value, index) { return value === array2[index]})

Rr, in ECMAScript 6 / CoffeeScript / TypeScript with Arrow Functions:

array1.length === array2.length && array1.every((value, index) => value === array2[index])

(Note: 'scalar' here means values that can be compared directly using === . So: numbers, strings, objects by reference, functions by reference. See the MDN reference for more info about the comparison operators).

UPDATE

From what I read from the comments, sorting the array and comparing may give accurate result:

const array2Sorted = array2.slice().sort();
array1.length === array2.length && array1.slice().sort().every(function(value, index) {
    return value === array2Sorted[index];
});

Eg:

array1 = [2,3,1,4];
array2 = [1,2,3,4];

Then the above code would give true

You can comma-separate shadows:

I use this function for dd/mm/yyyy format :

// (new Date()).fromString("3/9/2013") : 3 of september
// (new Date()).fromString("3/9/2013", false) : 9 of march
Date.prototype.fromString = function(str, ddmmyyyy) {
    var m = str.match(/(\d+)(-|\/)(\d+)(?:-|\/)(?:(\d+)\s+(\d+):(\d+)(?::(\d+))?(?:\.(\d+))?)?/);
    if(m[2] == "/"){
        if(ddmmyyyy === false)
            return new Date(+m[4], +m[1] - 1, +m[3], m[5] ? +m[5] : 0, m[6] ? +m[6] : 0, m[7] ? +m[7] : 0, m[8] ? +m[8] * 100 : 0);
        return new Date(+m[4], +m[3] - 1, +m[1], m[5] ? +m[5] : 0, m[6] ? +m[6] : 0, m[7] ? +m[7] : 0, m[8] ? +m[8] * 100 : 0);
    }
    return new Date(+m[1], +m[3] - 1, +m[4], m[5] ? +m[5] : 0, m[6] ? +m[6] : 0, m[7] ? +m[7] : 0, m[8] ? +m[8] * 100 : 0);
}

If you already installed "MongoDB", if you accidentally exit from the MongoDB server, then "restart your system".

This method solved me...

[On Windows only]

And also another method is there:

press:

Windows + R

type:

services.msc

and click "ok", it opens "services" window, and then search for "MongoDB Server" in the list. After you find "MongoDB Server", right-click and choose "start" from the pop-up menu.

The MongoDb Server will start running.

Hope it works!!

To get activity state data stored in onCreate(), first you have to save data in savedInstanceState by overriding SaveInstanceState(Bundle savedInstanceState) method.

When activity destroy SaveInstanceState(Bundle savedInstanceState) method gets called and there you save data you want to save. And you get same in onCreate() when activity restart.(savedInstanceState wont be null since you have saved some data in it before activity get destroyed)

To remove duplicates from a single column

 Sub removeDuplicate()
 'removeDuplicate Macro
 Columns("A:A").Select
 ActiveSheet.Range("$A$1:$A$117").RemoveDuplicates Columns:=Array(1), _ 
 Header:=xlNo 
 Range("A1").Select
 End Sub

if you have header then use Header:=xlYes

Increase your range as per your requirement.
you can make it to 1000 like this :

ActiveSheet.Range("$A$1:$A$1000")

Use (keyup.enter).

Angular can filter the key events for us. Angular has a special syntax for keyboard events. We can listen for just the Enter key by binding to Angular's keyup.enter pseudo-event.

It seems to work fine in Postgresql 9.5:

SELECT current_setting('TIMEZONE');

You can use DateFormat(java.text.*) to parse the date:

DateFormat df = new SimpleDateFormat("EEE MMM dd kk:mm:ss z yyyy", Locale.ENGLISH);
Date d = df.parse("Mon May 27 11:46:15 IST 2013")

You will have to change the locale to match your own (with this you will get 10:46:15). Then you can use the same code you have to convert it to a timestamp.

I've found that (at Chrome 56, OSX) the favicon state appears to be cached for the browser lifetime, so if a favicon isn't being loaded, it won't be until after restarting Chrome. It appears that it doesn't show up in the "application" tab in dev tools and isn't cleared by a hard reload or 'Clear site data'.

Here is a solution on pure js. You can do it with html5 saveAs. For example this lib could be helpful: https://github.com/eligrey/FileSaver.js
Look at the demo: http://eligrey.com/demos/FileSaver.js/
P.S. There is no information about json save, but you can do it changing file type to "application/json" and format to .json

I had similar problem and i solved it following way.

Solve as follows:

Function prototype declarations and global variable should be in test.h file and you can not initialize global variable in header file.

Function definition and use of global variable in test.c file

if you initialize global variables in header it will have following error

multiple definition of `_ test'| obj\Debug\main.o:path\test.c|1|first defined here|

Just declarations of global variables in Header file no initialization should work.

Hope it helps

Your main problem is you create new figures in your loop, so each vector gets drawn on a different figure. Here's what I came up with, let me know if it's still not what you expect:

CODE:

import numpy as np
import matplotlib.pyplot as plt
M = np.array([[1,1],[-2,2],[4,-7]])

rows,cols = M.T.shape

#Get absolute maxes for axis ranges to center origin
#This is optional
maxes = 1.1*np.amax(abs(M), axis = 0)

for i,l in enumerate(range(0,cols)):
    xs = [0,M[i,0]]
    ys = [0,M[i,1]]
    plt.plot(xs,ys)

plt.plot(0,0,'ok') #<-- plot a black point at the origin
plt.axis('equal')  #<-- set the axes to the same scale
plt.xlim([-maxes[0],maxes[0]]) #<-- set the x axis limits
plt.ylim([-maxes[1],maxes[1]]) #<-- set the y axis limits
plt.legend(['V'+str(i+1) for i in range(cols)]) #<-- give a legend
plt.grid(b=True, which='major') #<-- plot grid lines
plt.show()

OUTPUT:

EDIT CODE:

import numpy as np
import matplotlib.pyplot as plt
M = np.array([[1,1],[-2,2],[4,-7]])

rows,cols = M.T.shape

#Get absolute maxes for axis ranges to center origin
#This is optional
maxes = 1.1*np.amax(abs(M), axis = 0)
colors = ['b','r','k']


for i,l in enumerate(range(0,cols)):
    plt.axes().arrow(0,0,M[i,0],M[i,1],head_width=0.05,head_length=0.1,color = colors[i])

plt.plot(0,0,'ok') #<-- plot a black point at the origin
plt.axis('equal')  #<-- set the axes to the same scale
plt.xlim([-maxes[0],maxes[0]]) #<-- set the x axis limits
plt.ylim([-maxes[1],maxes[1]]) #<-- set the y axis limits
plt.grid(b=True, which='major') #<-- plot grid lines
plt.show()

EDIT OUTPUT:

I found the following command to run from command line:

vlc.exe --extraintf=http:logger --verbose=2 --file-logging --logfile=vlc-log.txt

FormBorderStyle = FormBorderStyle.Sizable;
TopMost = false;
WindowState = FormWindowState.Normal;

THIS CODE MAKE YOUR WINDOWS FULL SCREEN THIS WILL ALSO COVER WHOLE SCREEN

A form is not allowed to be a child element of a table, tbody or tr. Attempting to put one there will tend to cause the browser to move the form to it appears after the table (while leaving its contents — table rows, table cells, inputs, etc — behind).

You can have an entire table inside a form. You can have a form inside a table cell. You cannot have part of a table inside a form.

Use one form around the entire table. Then either use the clicked submit button to determine which row to process (to be quick) or process every row (allowing bulk updates).

HTML 5 introduces the form attribute. This allows you to provide one form per row outside the table and then associate all the form control in a given row with one of those forms using its id.

Switching to the smartphone network & disabling the web security tool installed on my computer solved the problem.

Many hosts will not allow you to create your own database through PHP, but you seem to have solved that.
Once the DB has been created, you can manipulate and populate it simply:

mysql_connect("localhost");
mysql_query("SOURCE file.sql");

If you are using non-parallel direct path loads then consider and benchmark not dropping the indexes at all, particularly if the indexes only cover a minority of the columns. Oracle has a mechanism for efficient maintenance of indexes on direct path loads.

Otherwise, I'd also advise making the indexes unusable instead of dropping them. Less chance of accidentally not recreating an index.

You are looking for the break statement.

$arr = array('one', 'two', 'three', 'four', 'stop', 'five');
while (list(, $val) = each($arr)) {
    if ($val == 'stop') {
        break;    /* You could also write 'break 1;' here. */
    }
    echo "$val<br />\n";
}

Use WebElement.send_keys method to simulate key typing.

name in the code (Username, Password) does not match actual name of the elements (username, password).

username = browser.find_element_by_name('username')
username.send_keys('user1')

password = browser.find_element_by_name('password')
password.send_keys('secret')

form = browser.find_element_by_id('loginForm')
form.submit()

# OR  browser.find_element_by_id('submit').click()

Since you are in a controller, the action method is given a Request parameter.

You can access all POST data with $request->request->all();. This returns a key-value pair array.

When using GET requests you access data using $request->query->all();

holy errors The reason for the code below is to show how to not void main every function and not to type return; for functions...... instead push everything into the sediment for which is the print function prototype... if you need to use useful functions ... you will have to below..... (p.s. this below is for people overwhelmed by these object and T templates which allow different variable declaration types(such as float and char) to use the same passed by value in a user defined function)

char arr[ ] = "This is a test";

string str(arr);


//  You can also assign directly to a string.
str = "This is another string";

can anyone tell me why c++ made arrays into pass by value one at a time and the only way to eliminate spaces and punctuation is the use of string tokens. I couldn't get around the problem when i was trying to delete spaces for a palindrome...

}

At first, you must specify your path, the path that your *.csv files are in there

path = 'f:\project\dataset'

You can change it based on your system.

then,

use dir function :

files = dir (strcat(path,'\*.csv'))

L = length (files);

for i=1:L
   image{i}=csvread(strcat(path,'\',file(i).name));   
   % process the image in here
end

pwd also can be used.

One example in order to understand, where the usage of ZEROFILL might be interesting:

In Germany, we have 5 digit zipcodes. However, those Codes may start with a Zero, so 80337 is a valid zipcode for munic, 01067 is a zipcode of Berlin.

As you see, any German citizen expects the zipcodes to be displayed as a 5 digit code, so 1067 looks strange.

In order to store those data, you could use a VARCHAR(5) or INT(5) ZEROFILL whereas the zerofilled integer has two big advantages:

1. Lot lesser storage space on hard disk
2. If you insert 1067, you still get 01067 back

Maybe this example helps understanding the use of ZEROFILL.

Procedural elements like loops are not part of the SQL language and can only be used inside the body of a procedural language function, procedure (Postgres 11 or later) or a DO statement, where such additional elements are defined by the respective procedural language. The default is PL/pgSQL, but there are others.

Example with plpgsql:

DO
$do$
BEGIN 
   FOR i IN 1..25 LOOP
      INSERT INTO playtime.meta_random_sample
         (col_i, col_id)                       -- declare target columns!
      SELECT  i,     id
      FROM   tbl
      ORDER  BY random()
      LIMIT  15000;
   END LOOP;
END
$do$;

For many tasks that can be solved with a loop, there is a shorter and faster set-based solution around the corner. Pure SQL equivalent for your example:

INSERT INTO playtime.meta_random_sample (col_i, col_id)
SELECT t.*
FROM   generate_series(1,25) i
CROSS  JOIN LATERAL (
   SELECT i, id
   FROM   tbl
   ORDER  BY random()
   LIMIT  15000
   ) t;

About generate_series():

• What is the expected behaviour for multiple set-returning functions in select clause?

About optimizing performance of random selections:

• Best way to select random rows PostgreSQL

An activity populates the ActionBar in its onCreateOptionsMenu() method.

Instead of using setcustomview(), just override onCreateOptionsMenu like this:

@Override    
public boolean onCreateOptionsMenu(Menu menu) {
  MenuInflater inflater = getMenuInflater();
  inflater.inflate(R.menu.mainmenu, menu);
  return true;
}

If an actions in the ActionBar is selected, the onOptionsItemSelected() method is called. It receives the selected action as parameter. Based on this information you code can decide what to do for example:

@Override
public boolean onOptionsItemSelected(MenuItem item) {
  switch (item.getItemId()) {
    case R.id.menuitem1:
      Toast.makeText(this, "Menu Item 1 selected", Toast.LENGTH_SHORT).show();
      break;
    case R.id.menuitem2:
      Toast.makeText(this, "Menu item 2 selected", Toast.LENGTH_SHORT).show();
      break;
  }
  return true;
}

When passing parameters through the URL you're able to retrieve the values as GET parameters.

Use this:

$variable = $_GET['param_name'];

//Or as you have it
$ppc = $_GET['ppc'];

It is safer to check for the variable first though:

if (isset($_GET['ppc'])) {
  $ppc = $_GET['ppc'];
} else {
  //Handle the case where there is no parameter
}

Here's a bit of reading on GET/POST params you should look at: http://php.net/manual/en/reserved.variables.get.php

EDIT: I see this answer still gets a lot of traffic years after making it. Please read comments attached to this answer, especially input from @emc who details a WordPress function which accomplishes this goal securely.

You have two possibilities:

1. non-static setter for static property/field;
2. using org.springframework.beans.factory.config.MethodInvokingFactoryBean to invoke a static setter.

In the first option you have a bean with a regular setter but instead setting an instance property you set the static property/field.

public void setTheProperty(Object value) {
    foo.bar.Class.STATIC_VALUE = value;
}

but in order to do this you need to have an instance of a bean that will expose this setter (its more like an workaround).

In the second case it would be done as follows:

<bean class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">
    <property name="staticMethod" value="foo.bar.Class.setTheProperty"/>
    <property name="arguments">
        <list>
            <ref bean="theProperty"/>
        </list>
   </property>
</bean>

On you case you will add a new setter on the Utils class:

public static setDataBaseAttr(Properties p)

and in your context you will configure it with the approach exemplified above, more or less like:

<bean class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">
    <property name="staticMethod" value="foo.bar.Utils.setDataBaseAttr"/>
    <property name="arguments">
        <list>
            <ref bean="dataBaseAttr"/>
        </list>
   </property>
</bean>

This solution can be applied only if the issue is on a WordPress installation!

If you don't have FTP access or too lazy to edit files,

You can use Increase Maximum Upload File Size plugin to increase the maximum upload file size.

Is your server single-threaded? If so, what polling / multiplexing function are you using?

Using select() does not work beyond the hard-coded maximum file descriptor limit set at compile-time, which is hopeless (normally 256, or a few more).

poll() is better but you will end up with the scalability problem with a large number of FDs repopulating the set each time around the loop.

epoll() should work well up to some other limit which you hit.

10k connections should be easy enough to achieve. Use a recent(ish) 2.6 kernel.

How many client machines did you use? Are you sure you didn't hit a client-side limit?

What I do usually when I commit and push (if anyone pushed his commit this solve the problem):

git reset --hard HEAD~1

git push -f origin

hope this help

Note: The first() method doesn't throw an exception as described in the original question. If you're getting this kind of exception, there is another error in your code.

The correct way to user first() and check for a result:

$user = User::where('mobile', Input::get('mobile'))->first(); // model or null
if (!$user) {
   // Do stuff if it doesn't exist.
}

Other techniques (not recommended, unnecessary overhead):

$user = User::where('mobile', Input::get('mobile'))->get();

if (!$user->isEmpty()){
    $firstUser = $user->first()
}

or

try {
    $user = User::where('mobile', Input::get('mobile'))->firstOrFail();
    // Do stuff when user exists.
} catch (ErrorException $e) {
    // Do stuff if it doesn't exist.
}

or

// Use either one of the below. 
$users = User::where('mobile', Input::get('mobile'))->get(); //Collection

if (count($users)){
    // Use the collection, to get the first item use $users->first().
    // Use the model if you used ->first();
}

Each one is a different way to get your required result.

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.

Try using the passive command before using ls.

This blog explains your problem neatly Async Best Practices.

The gist of it being you shouldn't use void as return for an async method, unless it's an async event handler, this is bad practice because it doesn't allow exceptions to be caught ;-).

Best practice would be to change the return type to Task. Also, try to code async all the way trough, make every async method call and be called from async methods. Except for a Main method in a console, which can't be async (before C# 7.1).

You will run into deadlocks with GUI and ASP.NET applications if you ignore this best practice. The deadlock occurs because these applications runs on a context that allows only one thread and won't relinquish it to the async thread. This means the GUI waits synchronously for a return, while the async method waits for the context: deadlock.

This behaviour won't happen in a console application, because it runs on context with a thread pool. The async method will return on another thread which will be scheduled. This is why a test console app will work, but the same calls will deadlock in other applications...

In my case, the error was triggered by duplicating an import of a component in the module.

it was the update version of Codemwnci. his code is quite fine and works great except the error message. To avoid error you must change the condition statement.

  // Listen for changes in the text
textField.getDocument().addDocumentListener(new DocumentListener() {
  public void changedUpdate(DocumentEvent e) {
    warn();
  }
  public void removeUpdate(DocumentEvent e) {
    warn();
  }
  public void insertUpdate(DocumentEvent e) {
    warn();
  }

  public void warn() {
     if (textField.getText().length()>0){
       JOptionPane.showMessageDialog(null,
          "Error: Please enter number bigger than 0", "Error Massage",
          JOptionPane.ERROR_MESSAGE);
     }
  }
});

Using $emit and $broadcast, (as mentioned by walv in the comments above)

To fire an event upwards (from child to parent)

$scope.$emit('myTestEvent', 'Data to send');

To fire an event downwards (from parent to child)

$scope.$broadcast('myTestEvent', {
  someProp: 'Sending you some data'
});

and finally to listen

$scope.$on('myTestEvent', function (event, data) {
  console.log(data);
});

1st Reason could be the ending tag of your application's web.xml file which could not have been closed properly.

web.xml might be ending with <web-app>, but must end with </web-app>

2nd Reason which worked in my case could be the lib folder of your tomcat must contain the supporting jar file of your database.

ojdbc on case of Oracle or sqljdbc in case of SqlServer

Please ensure that you have following import. Ofcourse other standard imports

import org.springframework.core.io.FileSystemResource


    void uploadzipFiles(String token) {

        RestBuilder rest = new RestBuilder(connectTimeout:10000, readTimeout:20000)

        def zipFile = new File("testdata.zip")
        def Id = "001G00000"
        MultiValueMap<String, String> form = new LinkedMultiValueMap<String, String>()
        form.add("id", id)
        form.add('file',new FileSystemResource(zipFile))
        def urld ='''http://URL''';
        def resp = rest.post(urld) {
            header('X-Auth-Token', clientSecret)
            contentType "multipart/form-data"
            body(form)
        }
        println "resp::"+resp
        println "resp::"+resp.text
        println "resp::"+resp.headers
        println "resp::"+resp.body
        println "resp::"+resp.status
    }

The first and foremost step to diagnose is to check the Cassandra logs.

Find out the process and there will be hints in the command line parameters to tell you where the logs files are.

ps aux | grep cassandra

In my case, it was in default location /etc/cassandra/conf/cassandra.yaml (if you installed the yum package).

Make sure three things are configured and configured the same host/ip.

1. listen_address - you may leave it blank it will default to hostname/first IP binding with eth0 network card
2. rpc_address - this is optional, leave blank if you want it to be same as listen_address
3. seeds - this is a double quoted string of comma-separated list of IP addresses or hostnames. This was default to a hardcoded "127.0.0.1", changing it to the same as list_address and restart of Cassandra service made it work for me.

Odds are good you did the right stuff on the back end in getting the date, but there's nothing to indicate that you didn't take that GMT time and format it according to your machine's current locale.

final Date currentTime = new Date();

final SimpleDateFormat sdf =
        new SimpleDateFormat("EEE, MMM d, yyyy hh:mm:ss a z");

// Give it to me in GMT time.
sdf.setTimeZone(TimeZone.getTimeZone("GMT"));
System.out.println("GMT time: " + sdf.format(currentTime));

The key is to use your own DateFormat, not the system provided one. That way you can set the DateFormat's timezone to what you wish, instead of it being set to the Locale's timezone.

Spring provides an elegant org.springframework.util.StopWatch class (spring-core module).

StopWatch stopWatch = new StopWatch();

stopWatch.start();
// Do something
stopWatch.stop();

System.out.println(stopWatch.getTotalTimeMillis());

No, there is no built in conversion for this. You'll need to create a constructor, like you mentioned, or some other conversion method.

Also, since BaseClass is not a DerivedClass, myDerivedObject will be null, andd the last line above will throw a null ref exception.

as ehogue said, put this in your CREATE TABLE

FOREIGN KEY (customer_id) REFERENCES customers(customer_id) 

alternatively, if you already have the table created, use an ALTER TABLE command:

ALTER TABLE `accounts`
  ADD CONSTRAINT `FK_myKey` FOREIGN KEY (`customer_id`) REFERENCES `customers` (`customer_id`) ON DELETE CASCADE ON UPDATE CASCADE;

One good way to start learning these commands is using the MySQL GUI Tools, which give you a more "visual" interface for working with your database. The real benefit to that (over Access's method), is that after designing your table via the GUI, it shows you the SQL it's going to run, and hence you can learn from that.

Try with below code.

Like GridView in LinkButton, Label, HtmlAnchor and HtmlInputControl.

<asp:GridView ID="mainGrid" runat="server" AutoGenerateColumns="false" CssClass="table table-bordered table-hover tablesorter"
    OnRowDataBound="mainGrid_RowDataBound"  EmptyDataText="No Data Found.">

    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        Label lblName = (Label)e.Row.FindControl("lblName");
        LinkButton btnLink = (LinkButton)e.Row.FindControl("btnLink");
        HtmlAnchor btnAnchor = (HtmlAnchor)e.Row.FindControl("btnAnchor");
        HtmlInputControl hdnBtnInput = (HtmlInputControl)e.Row.FindControl("hdnBtnInput");
    }
}

Here is an example that lists all the files on my desktop. you should change the path variable to your path.

Instead of printing the file's name with System.out.println, you should place your own code to operate on the file.

public static void main(String[] args) {
    File path = new File("c:/documents and settings/Zachary/desktop");

    File [] files = path.listFiles();
    for (int i = 0; i < files.length; i++){
        if (files[i].isFile()){ //this line weeds out other directories/folders
            System.out.println(files[i]);
        }
    }
}

Similar to POsha's answer but this is what worked for me on ubuntu 19

sudo npm i -g ngrok --unsafe-perm=true --allow-root

From this link

https://github.com/inconshreveable/ngrok/issues/429

For you to output foo {1, 2, 3} you have to do something like:

string t = "1, 2, 3";
string v = String.Format(" foo {{{0}}}", t);

To output a { you use {{ and to output a } you use }}.

or Now, you can also use c# string interpolation like this (feature available in C# 6.0)

Escaping Brackets: String Interpolation $(""). it is new feature in C# 6.0

var inVal = "1, 2, 3";
var outVal = $" foo {{{inVal}}}";
//Output will be:  foo {1, 2, 3}

Some examples of formatted output to stdout and stderr:

printf("%s", "Hello world\n");              // "Hello world" on stdout (using printf)
fprintf(stdout, "%s", "Hello world\n");     // "Hello world" on stdout (using fprintf)
fprintf(stderr, "%s", "Stack overflow!\n"); // Error message on stderr (using fprintf)

This worked for me:

^(?=.*[0-9])(?=.*[a-z])(?=.*[A-Z])(?=.*[@$!%*?&])([a-zA-Z0-9@$!%*?&]{8,})$

• At least 8 characters long;
• One lowercase, one uppercase, one number and one special character;
• No whitespaces.

With ps or similar tools you will only get the amount of memory pages allocated by that process. This number is correct, but:

• does not reflect the actual amount of memory used by the application, only the amount of memory reserved for it

• can be misleading if pages are shared, for example by several threads or by using dynamically linked libraries

If you really want to know what amount of memory your application actually uses, you need to run it within a profiler. For example, Valgrind can give you insights about the amount of memory used, and, more importantly, about possible memory leaks in your program. The heap profiler tool of Valgrind is called 'massif':

Massif is a heap profiler. It performs detailed heap profiling by taking regular snapshots of a program's heap. It produces a graph showing heap usage over time, including information about which parts of the program are responsible for the most memory allocations. The graph is supplemented by a text or HTML file that includes more information for determining where the most memory is being allocated. Massif runs programs about 20x slower than normal.

As explained in the Valgrind documentation, you need to run the program through Valgrind:

valgrind --tool=massif <executable> <arguments>

Massif writes a dump of memory usage snapshots (e.g. massif.out.12345). These provide, (1) a timeline of memory usage, (2) for each snapshot, a record of where in your program memory was allocated. A great graphical tool for analyzing these files is massif-visualizer. But I found ms_print, a simple text-based tool shipped with Valgrind, to be of great help already.

To find memory leaks, use the (default) memcheck tool of valgrind.

You'll need to use sp_addlinkedserver to create a server link. See the reference documentation for usage. Once the server link is established, you'll construct the query as normal, just prefixing the database name with the other server. I.E:

-- FROM DB1
SELECT *
FROM [MyDatabaseOnDB1].[dbo].[MyTable] tab1
    INNER JOIN [DB2].[MyDatabaseOnDB2].[dbo].[MyOtherTable] tab2
        ON tab1.ID = tab2.ID

Once the link is established, you can also use OPENQUERY to execute a SQL statement on the remote server and transfer only the data back to you. This can be a bit faster, and it will let the remote server optimize your query. If you cache the data in a temporary (or in-memory) table on DB1 in the example above, then you'll be able to query it just like joining a standard table. For example:

-- Fetch data from the other database server
SELECT *
INTO #myTempTable
FROM OPENQUERY([DB2], 'SELECT * FROM [MyDatabaseOnDB2].[dbo].[MyOtherTable]')

-- Now I can join my temp table to see the data
SELECT * FROM [MyDatabaseOnDB1].[dbo].[MyTable] tab1
    INNER JOIN #myTempTable tab2 ON tab1.ID = tab2.ID

Check out the documentation for OPENQUERY to see some more examples. The example above is pretty contrived. I would definitely use the first method in this specific example, but the second option using OPENQUERY can save some time and performance if you use the query to filter out some data.

I know it's an old question, but I believe still valid even in 2018.

There is an option to Take a bug report hidden in Developer options in every android device.

NOTE: This would dump whole system log

How to enable developer options? see: https://developer.android.com/studio/debug/dev-options

What works for me:

1. Restart your device (in order to create minimum garbage logs for developer to analyze)
2. Reproduce your bug
3. Go to Settings -> Developer options -> Take a bug report
4. Wait for Android system to collect the logs (watch the progressbar in notification)
5. Once it completes, tap the notification to share it (you can use gmail or whetever else)

how to read this? open bugreport-1960-01-01-hh-mm-ss.txt

you probably want to look for something like this:

------ SYSTEM LOG (logcat -v threadtime -v printable -d *:v) ------
--------- beginning of crash
06-13 14:37:36.542 19294 19294 E AndroidRuntime: FATAL EXCEPTION: main

or:

------ SYSTEM LOG (logcat -v threadtime -v printable -d *:v) ------
--------- beginning of main

For those who are struggling to get this working with IE11

HTML

<div ng-style="getBackgroundStyle(imagepath)"></div>

JS

$scope.getBackgroundStyle = function(imagepath){
    return {
        'background-image':'url(' + imagepath + ')'
    }
}

You can use sed for this. For example:

$ sed -n '/Feb 23 13:55/,/Feb 23 14:00/p' /var/log/mail.log
Feb 23 13:55:01 messagerie postfix/smtpd[20964]: connect from localhost[127.0.0.1]
Feb 23 13:55:01 messagerie postfix/smtpd[20964]: lost connection after CONNECT from localhost[127.0.0.1]
Feb 23 13:55:01 messagerie postfix/smtpd[20964]: disconnect from localhost[127.0.0.1]
Feb 23 13:55:01 messagerie pop3d: Connection, ip=[::ffff:127.0.0.1]
...

How it works

The -n switch tells sed to not output each line of the file it reads (default behaviour).

The last p after the regular expressions tells it to print lines that match the preceding expression.

The expression '/pattern1/,/pattern2/' will print everything that is between first pattern and second pattern. In this case it will print every line it finds between the string Feb 23 13:55 and the string Feb 23 14:00.

The answer on 2018 is the selected one here: Pycharm: "unresolved reference" error on the IDE when opening a working project

Just be aware that you can only add one Content Root but you can add several Source Folders. No need to touch __init__.py files.

You can use GetCustomAttributesData() and GetCustomAttributes():

var attributeData = typeof(Book).GetProperty("Name").GetCustomAttributesData();
var attributes = typeof(Book).GetProperty("Name").GetCustomAttributes(false);

If you use the database information_schema, you can use this mysql code (the where part makes the query not show tables that have a null value for rows):

SELECT TABLE_NAME, TABLE_ROWS
FROM `TABLES`
WHERE `TABLE_ROWS` >=0

To expound on Numenor's answer you can do something like, Format(Now(),"HH:mm:ss") using these custom date/time formating options

For everyone who is tempted to downvote this answer please be aware that the question was originally tagged VB and vbscript hence my answer, the VB tag was edited out leaving only the vbscript tag. The OP accepted this answer which I take to mean that it gave him the information that he needed.

All of the above is just over-complicating something very simple. An application server contains a web server, an application server just has a couple more additions/extensions to it than standard web servers. If you look at TomEE as an example:

CDI - Apache OpenWebBeans
EJB - Apache OpenEJB
JPA - Apache OpenJPA
JSF - Apache MyFaces
JSP - Apache Tomcat
JSTL - Apache Tomcat
JTA - Apache Geronimo Transaction
Servlet - Apache Tomcat
Javamail - Apache Geronimo JavaMail
Bean Validation - Apache BVal

You will see that Tomcat (Web container/server) is just another tool in the app servers arsenal. You can get JPA and the other tech in the web server as well if you want, but the application servers just package all of these things for your convenience. To be fully classified as an app server you essentially need to comply with a list of tools set forth by some standard.

You could check whether the value of your selectOneMenu component belongs to the list of subjects.

Namely:

public void subjectSelectionChanged() {
    // Cancel if subject is manually written
    if (!subjectList.contains(aktNachricht.subject)) { return; }
    // Write your code here in case the user selected (or wrote) an item of the list
    // ....
}

Supposedly subjectList is a collection type, like ArrayList. Of course here your code will run in case the user writes an item of your selectOneMenu list.

IF the table is alias t

SELECT t.Present , t.previous, t.previous- t.Present AS Difference
FROM   temp1 as t

I needed a solution with a retry. This code will run until the process is found and then kill it. You can set a timeout or anything if you like.

Notes:

• The ".exe" is mandatory
• You could make a file runnable with parameters, version below

    :: Set programm you want to kill
    :: Fileextension is mandatory
    SET KillProg=explorer.exe

    :: Set waiting time between 2 requests in seconds
    SET /A "_wait=3"

    :ProcessNotFound
        tasklist /NH /FI "IMAGENAME eq %KillProg%" | FIND /I "%KillProg%"
        IF "%ERRORLEVEL%"=="0" (
            TASKKILL.EXE /F /T /IM %KillProg%
        ) ELSE (
            timeout /t %_wait%
            GOTO :ProcessNotFound
        )

taskkill.bat:

    :: Get program name from argumentlist
    IF NOT "%~1"=="" (
        SET "KillProg=%~1"
    ) ELSE (
        ECHO Usage: "%~nx0" ProgramToKill.exe & EXIT /B
    )

    :: Set waiting time between 2 requests in seconds
    SET /A "_wait=3"

    :ProcessNotFound
        tasklist /NH /FI "IMAGENAME eq %KillProg%" | FIND /I "%KillProg%"
        IF "%ERRORLEVEL%"=="0" (
            TASKKILL.EXE /F /T /IM %KillProg%
        ) ELSE (
            timeout /t %_wait%
            GOTO :ProcessNotFound
        )

Run with .\taskkill.bat ProgramToKill.exe

I know this is an old question, but since php7.0 you can use the null coalescing operator (another resource).

It similar to the ternary operator, but will behave like isset on the lefthand operand instead of just using its boolean value.

$slide = $_GET["id"] ?? 'fallback';

So if $_GET["id"] is set, it returns the value. If not, it returns the fallback. I found this very helpful for $_POST, $_GET, or any passed parameters, etc

$slide = $_GET["id"] ?? '';

if (trim($slide) == 'link1') ...

This :

$a = array ('zero','one','two', 'three');

foreach ($a as &$v) {

}

foreach ($a as $v) {
    echo $v.PHP_EOL;
}

is the same as

$a = array ('zero','one','two', 'three');

$v = &$a[3];

for ($i = 0; $i < 4; $i++) {
    $v = $a[$i];
    echo $v.PHP_EOL; 
}

OR

$a = array ('zero','one','two', 'three');

for ($i = 0; $i < 4; $i++) {
    $a[3] = $a[$i];
    echo $a[3].PHP_EOL; 
}

OR

$a = array ('zero','one','two', 'three');

$a[3] = $a[0];
echo $a[3].PHP_EOL;

$a[3] = $a[1]; 
echo $a[3].PHP_EOL;

$a[3] = $a[2];
echo $a[3].PHP_EOL;

$a[3] = $a[3]; 
echo $a[3].PHP_EOL;

For simple document, I sometimes use verbatim, but listing is nice for big chunk of code.

With your question edit, I see your problem. Let's say the current directory is /home/yourname ... in this case, your command below:

sed 's/xxx/'$PWD'/'

will be expanded to

sed `s/xxx//home/yourname//

which is not valid. You need to put a \ character in front of each / in your $PWD if you want to do this.

Find out the element which is larger than the body (element which is causing the page to scroll) and just set it's position to fixed. NOTE: I'm not talking to change the position of draggable elements. Draggable elements can be dragged out of body only when there's an element larger than body (mostly in width).

I combined, minified and extended (some more checks) the answers from @Bijay Rungta and @J.C. Inacio

Here is the what I have done to avoid CrossThreadException and writing to the textbox from another thread.

Here is my Button.Click function- I want to generate a random number of threads and then get their IDs by calling the getID() method and the TextBox value while being in that worker thread.

private void btnAppend_Click(object sender, EventArgs e) 
{
    Random n = new Random();

    for (int i = 0; i < n.Next(1,5); i++)
    {
        label2.Text = "UI Id" + ((Thread.CurrentThread.ManagedThreadId).ToString());
        Thread t = new Thread(getId);
        t.Start();
    }
}

Here is getId (workerThread) code:

public void getId()
{
    int id = Thread.CurrentThread.ManagedThreadId;
    //Note that, I have collected threadId just before calling this.Invoke
    //method else it would be same as of UI thread inside the below code block 
    this.Invoke((MethodInvoker)delegate ()
    {
        inpTxt.Text += "My id is" +"--"+id+Environment.NewLine; 
    });
}

If the audio wrapped into the avi is not mp3-format to start with, you may need to specify -acodec mp3 as an additional parameter. Or whatever your mp3 codec is (on Linux systems its probably -acodec libmp3lame). You may also get the same effect, platform-agnostic, by instead specifying -f mp3 to "force" the format to mp3, although not all versions of ffmpeg still support that switch. Your Mileage May Vary.

Well seeing this thread as a beginner got my head spinning. Hence came up with a simple shortcut.

Though str.strip() works to remove leading & trailing spaces it does nothing for spaces between characters.

words=input("Enter the word to test")
# If I have a user enter discontinous threads it becomes a problem
# input = "   he llo, ho w are y ou  "
n=words.strip()
print(n)
# output "he llo, ho w are y ou" - only leading & trailing spaces are removed 

Instead use str.replace() to make more sense plus less error & more to the point. The following code can generalize the use of str.replace()

def whitespace(words):
    r=words.replace(' ','') # removes all whitespace
    n=r.replace(',','|') # other uses of replace
    return n
def run():
    words=input("Enter the word to test") # take user input
    m=whitespace(words) #encase the def in run() to imporve usability on various functions
    o=m.count('f') # for testing
    return m,o
print(run())
output- ('hello|howareyou', 0)

Can be helpful while inheriting the same in diff. functions.

If you don't care about a minimum width for the div and really just don't want the div to expand across the whole container, you can float it left -- floated divs by default expand to support their contents, like so:

<form>
    <div style="float: left; background-color: blue">
        <input type="button" name="blah" value="lots and lots of characters"/>
        <input type="button" name="blah2" value="some characters"/>
    </div>
</form>

You can also use a Subject and trigger its next() function from promise. See sample below:

Add code like below ( I used service )

class UserService {_x000D_
  private createUserSubject: Subject < any > ;_x000D_
_x000D_
  createUserWithEmailAndPassword() {_x000D_
    if (this.createUserSubject) {_x000D_
      return this.createUserSubject;_x000D_
    } else {_x000D_
      this.createUserSubject = new Subject < any > ();_x000D_
      firebase.auth().createUserWithEmailAndPassword(email,_x000D_
          password)_x000D_
        .then(function(firebaseUser) {_x000D_
          // do something to update your UI component_x000D_
          // pass user object to UI component_x000D_
          this.createUserSubject.next(firebaseUser);_x000D_
        })_x000D_
        .catch(function(error) {_x000D_
          // Handle Errors here._x000D_
          var errorCode = error.code;_x000D_
          var errorMessage = error.message;_x000D_
          this.createUserSubject.error(error);_x000D_
          // ..._x000D_
        });_x000D_
    }_x000D_
_x000D_
  }_x000D_
}

Create User From Component like below

class UserComponent {_x000D_
  constructor(private userService: UserService) {_x000D_
    this.userService.createUserWithEmailAndPassword().subscribe(user => console.log(user), error => console.log(error);_x000D_
    }_x000D_
  }

For Perfect DateTime Match in SQL Server

SELECT ID FROM [Table Name] WHERE (DateLog between '2017-02-16 **00:00:00.000**' and '2017-12-16 **23:59:00.999**') ORDER BY DateLog DESC

In windows, you can use _getch() in the

<conio.h>

header.

To solve the problem I use ${string_prompt} variable. It shows a input dialog when application runs. I can set the date/time manually at that dialog.

1. Move cursor at the end of file path.

2. Click variables and select string_prompt

3. Select Apply and Run

I am promoting my comment to an answer:

The easy way is:

You could draw in the original 'frame' itself instead of using gray image.

The hard way (method you were trying to implement):

backtorgb = cv2.cvtColor(gray,cv2.COLOR_GRAY2RGB) is the correct syntax.

If you want to fix vbs associations type

regsvr32 vbscript.dll
regsvr32 jscript.dll
regsvr32 wshext.dll
regsvr32 wshom.ocx
regsvr32 wshcon.dll
regsvr32 scrrun.dll

Also if you can't use vbs due to management then convert your script to a vb.net program which is designed to be easy, is easy, and takes 5 minutes.

Big difference is functions and subs are both called using brackets rather than just functions.

So the compilers are installed on all computers with .NET installed.

See this article here on how to make a .NET exe. Note the sample is for a scripting host. You can't use this, you have to put your vbs code in as .NET code.

How can I convert a VBScript to an executable (EXE) file?

How to import images into the gallery of an Android Virtual Device using Android Studio: I'm using Android Studio 1.4.1 and a API 15 virtual device.

Warning: This is manual intensive so it is not a good solution for a large number of images.

1. Create a virtual device using Android's Device Manager (AVD), Menu /Tools/Android/AVD Manager.
2. Start this virtual device.
3. Start the Android Device monitor, Menu */Tools/Android/Android Device Monitor. In the Devices tab (upper left) you should see your device. It should be Online (see this screenshot)
4. On the right window is the File Explorer. Go there and select the /mnt/sdcard/Pictures directory. It should be highlighted (see this screenshot)
5. Add jpegs to this directory by clicking on the Push a file onto the device icon (the little phone icon I highlighted in the above screenshot. You can add only one photo at a time, dadburnit.
6. Go to your device and run the Dev Tools app.
7. Scroll down and select Media Provider.
8. Click on the Scan SD Card button. This should copy the images you added in step 5 to the gallery. Go to the gallery and look, they should be there.

cast to an int then do a .toString(). It is ugly but it works.

Mark Russinovich wrote a terrific tool called AccessChk that lets you get this information from the command line. No installation is necessary.

http://technet.microsoft.com/en-us/sysinternals/bb664922.aspx

For example:

accesschk.exe /accepteula -q -a SeServiceLogonRight

Returns this for me:

IIS APPPOOL\DefaultAppPool
IIS APPPOOL\Classic .NET AppPool
NT SERVICE\ALL SERVICES

By contrast, whoami /priv and whoami /all were missing some entries for me, like SeServiceLogonRight.

Have a look at the documentation. Use the intValue method:

NSNumber *number = [dict objectForKey:@"integer"];
int intValue = [number intValue];

Great article i found what worked best for me was to add a % to the size

.wrap {
margin-top:5%;
margin-bottom:5%;
height:100%;
display:block;}

I agree with japollock way up there--throw an acception when you are uncertain about the outcome of an operation. Calls to APIs, accessing filesystems, database calls, etc. Anytime you are moving past the "boundaries" of your programming languages.

I'd like to add, feel free to throw a standard exception. Unless you are going to do something "different" (ignore, email, log, show that twitter whale picture thingy, etc), then don't bother with custom exceptions.

Update table set column = (select...)

never worked for me since set only expects 1 value - SQL Error: ORA-01427: single-row subquery returns more than one row.

here's the solution:

BEGIN
For i in (select id, name, desc from table1) 
LOOP
Update table2 set name = i.name, desc = i.desc where id = i.id;
END LOOP;
END;

That's how exactly you run it on SQLDeveloper worksheet. They say it's slow but that's the only solution that worked for me on this case.

There is an overload of Url.Action that takes your desired protocol (e.g. http, https) as an argument - if you specify this, you get a fully qualified URL.

Here's an example that uses the protocol of the current request in an action method:

var fullUrl = this.Url.Action("Edit", "Posts", new { id = 5 }, this.Request.Url.Scheme);

HtmlHelper (@Html) also has an overload of the ActionLink method that you can use in razor to create an anchor element, but it also requires the hostName and fragment parameters. So I'd just opt to use @Url.Action again:

<span>
  Copy
  <a href='@Url.Action("About", "Home", null, Request.Url.Scheme)'>this link</a> 
  and post it anywhere on the internet!
</span>

This is also working at my end...

<div style="width: 100px; height: 100px; float: left; position: relative;">
    <div
        style="width: 100%; height: 40px; position: absolute; top: 50%; left: 0; margin-top: -20px; line-height:19px; text-align: center; z-index: 999999999999999">
        99%<Br />
        Total
    </div>
    <canvas id="chart-area" width="100" height="100" />
</div>

I think you can use SeriesGroupBy.nunique:

print (df.groupby('param')['group'].nunique())
param
a    2
b    1
Name: group, dtype: int64

Another solution with unique, then create new df by DataFrame.from_records, reshape to Series by stack and last value_counts:

a = df[df.param.notnull()].groupby('group')['param'].unique()
print (pd.DataFrame.from_records(a.values.tolist()).stack().value_counts())
a    2
b    1
dtype: int64

In addition at the Daniel Vassallo solution, if you use SQL Server 2016+, there is another solution that I used in some cases without considerable lost of performances.

You can create just a table with only the common field and add a single column with the JSON string that contains all the subtype specific fields.

I have tested this design for manage inheritance and I am very happy for the flexibility that I can use in the relative application.

the following code works for me. It requires openCV (import cv2).

The code is composed of an infinite loop that is continuously looking for a key pressed. In this case, when the 'q' key is pressed, the program ends. Other keys can be pressed (in this example 'b' or 'k') to perform different actions such as change a variable value or execute a function.

import cv2

while True:
    k = cv2.waitKey(1) & 0xFF
    # press 'q' to exit
    if k == ord('q'):

you can use super while extending Exception

if (pass.length() < minPassLength)
    throw new InvalidPassException("The password provided is too short");
 } catch (NullPointerException e) {
    throw new InvalidPassException("No password provided", e);
 }


// A custom business exception
class InvalidPassException extends Exception {

InvalidPassException() {

}

InvalidPassException(String message) {
    super(message);
}
InvalidPassException(String message, Throwable cause) {
   super(message, cause);
}

}

}

Style the td and th instead

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

And also to make it so there is no spacing between cells use:

table {
    border-collapse: collapse;
}

(also note, you have border-style: none; which should be border-style: solid;)

At first see this question to see how you can find if a link has a jQuery handler assigned to it.

Next use:

$("a").attr("onclick")

to see if there is a javascript event assigned to it.

If any of the above is true, then call the click method. If not, get the link:

$("a").attr("href")

and follow it.

I am afraid I don't know what to do if addEventListener is used to add an event handler. If you are in charge of the full page source, use only jQuery event handlers.

1. Right-click on your table and pick option Backup..
2. On File Options, set Filepath/Filename and pick PLAIN for Format
3. Ignore Dump Options #1 tab
4. In Dump Options #2 tab, check USE INSERT COMMANDS
5. In Dump Options #2 tab, check Use Column Inserts if you want column names in your inserts.
6. Hit Backup button

edit: With Flash you can communicate between any window, ANY browser (yes, from FF to IE at runtime ) ..ANY form of instance of flash (ShockWave/activeX)

LDAP is also used to store your credentials in a network security system and retrieve it with your password and decrypted key giving you access to the services.

Note: if you need to use sudo, do this:

sudo bash -c 'cat file2 >> file1'

The usual method of simply prepending sudo to the command will fail, since the privilege escalation doesn't carry over into the output redirection.

Small improvement to the code from ryyst (who got the most votes) is to not use dynamically allocated decoding table but rather static const precomputed table. This eliminates the use of pointer and initialization of the table, and also avoids memory leakage if one forgets to clean up the decoding table with base64_cleanup() (by the way, in base64_cleanup(), after calling free(decoding_table), one should have decoding_table=NULL, otherwise accidentally calling base64_decode after base64_cleanup() will crash or cause undetermined behavior). Another solution could be to use std::unique_ptr...but I'm satisfied with just having const char[256] on the stack and avoid using pointers alltogether - the code looks cleaner and shorter this way.

The decoding table is computed as follows:

const char encoding_table[] = { 
    'A', 'B', 'C', 'D', 'E', 'F', 'G', 'H',
    'I', 'J', 'K', 'L', 'M', 'N', 'O', 'P',
    'Q', 'R', 'S', 'T', 'U', 'V', 'W', 'X',
    'Y', 'Z', 'a', 'b', 'c', 'd', 'e', 'f',
    'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n',
    'o', 'p', 'q', 'r', 's', 't', 'u', 'v',
    'w', 'x', 'y', 'z', '0', '1', '2', '3',
    '4', '5', '6', '7', '8', '9', '+', '/' };

unsigned char decoding_table[256];

for (int i = 0; i < 256; i++)
    decoding_table[i] = '\0';

for (int i = 0; i < 64; i++)
    decoding_table[(unsigned char)encoding_table[i]] = i;

for (int i = 0; i < 256; i++)
    cout << "0x" << (int(decoding_table[i]) < 16 ? "0" : "") << hex << int(decoding_table[i]) << (i != 255 ? "," : "") << ((i+1) % 16 == 0 ? '\n' : '\0');

cin.ignore();

and the modified code I am using is:

        static const char encoding_table[] = { 
            'A', 'B', 'C', 'D', 'E', 'F', 'G', 'H',
            'I', 'J', 'K', 'L', 'M', 'N', 'O', 'P',
            'Q', 'R', 'S', 'T', 'U', 'V', 'W', 'X',
            'Y', 'Z', 'a', 'b', 'c', 'd', 'e', 'f',
            'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n',
            'o', 'p', 'q', 'r', 's', 't', 'u', 'v',
            'w', 'x', 'y', 'z', '0', '1', '2', '3',
            '4', '5', '6', '7', '8', '9', '+', '/' };

        static const unsigned char decoding_table[256] = {

I love jtbandes answer, but since it is pretty long, I will add my own compact answer:

==, ===, eql?, equal?
are 4 comparators, ie. 4 ways to compare 2 objects, in Ruby.
As, in Ruby, all comparators (and most operators) are actually method-calls, you can change, overwrite, and define the semantics of these comparing methods yourself. However, it is important to understand, when Ruby's internal language constructs use which comparator:

== (value comparison)
Ruby uses :== everywhere to compare the values of 2 objects, eg. Hash-values:

{a: 'z'}  ==  {a: 'Z'}    # => false
{a: 1}    ==  {a: 1.0}    # => true

=== (case comparison)
Ruby uses :=== in case/when constructs. The following code snippets are logically identical:

case foo
  when bar;  p 'do something'
end

if bar === foo
  p 'do something'
end

eql? (Hash-key comparison)
Ruby uses :eql? (in combination with the method hash) to compare Hash-keys. In most classes :eql? is identical with :==.
Knowledge about :eql? is only important, when you want to create your own special classes:

class Equ
  attr_accessor :val
  alias_method  :initialize, :val=
  def hash()           self.val % 2             end
  def eql?(other)      self.hash == other.hash  end
end

h = {Equ.new(3) => 3,  Equ.new(8) => 8,  Equ.new(15) => 15}    #3 entries, but 2 are :eql?
h.size            # => 2
h[Equ.new(27)]    # => 15

Note: The commonly used Ruby-class Set also relies on Hash-key-comparison.

equal? (object identity comparison)
Ruby uses :equal? to check if two objects are identical. This method (of class BasicObject) is not supposed to be overwritten.

obj = obj2 = 'a'
obj.equal? obj2       # => true
obj.equal? obj.dup    # => false

You can use jackson library and simply use these 3 lines to convert your json file to Java Object.

ObjectMapper mapper = new ObjectMapper();
InputStream is = Test.class.getResourceAsStream("/test.json");
testObj = mapper.readValue(is, Test.class);

While @Andre is correct that there are issues with pseudo elements and their support, especially in older (IE) browsers, that support is improving all the time.

As for your question of, are there any issues, I'd say I've not really seen any, although the syntax for the pseudo-element can be a bit tricky, especially when first sussing it out. So:

div#top-level
  declarations: ...
  div.inside
    declarations: ...
    &:first-child
      declarations: ...

which compiles as one would expect:

div#top-level{
  declarations... }
div#top-level div.inside {
  declarations... }
div#top-level div.inside:first-child {
  declarations... }

I haven't seen any documentation on any of this, save for the statement that "sass can do everything that css can do." As always, with Haml and SASS the indentation is everything.

The xsd file is the schema of the xml file - it defines which elements may occur and their restrictions (like amount, order, boundaries, relationships,...)

This is my working solution:

select tabname as table_name
from syscat.tables
where tabschema = 'schema_name' -- put schema name here
      and type = 'T'
order by tabname

See this snippet: (C#)

    private Microsoft.Office.Interop.Excel.Application xla;
    Workbook wb;
    Worksheet ws;
    Range rg;
    ..........

        xla = new Microsoft.Office.Interop.Excel.Application();
        wb = xla.Workbooks.Add(XlSheetType.xlWorksheet);
        ws = (Worksheet)xla.ActiveSheet;
        rg = (Range)ws.Cells[1, 2];
        rg.ColumnWidth = 10;
        rg.Value2 = "Frequency";
        rg = (Range)ws.Cells[1, 3];
        rg.ColumnWidth = 15;
        rg.Value2 = "Impudence";
        rg = (Range)ws.Cells[1, 4];
        rg.ColumnWidth = 8;
        rg.Value2 = "Phase";

First download this JavaScript code, JSON2.js, that will help us serialize the object into a string.

In my example I'm posting the rows of a jqGrid via Ajax:

    var commissions = new Array();
    // Do several row data and do some push. In this example is just one push.
    var rowData = $(GRID_AGENTS).getRowData(ids[i]);
    commissions.push(rowData);
    $.ajax({
        type: "POST",
        traditional: true,
        url: '<%= Url.Content("~/") %>' + AREA + CONTROLLER + 'SubmitCommissions',
        async: true,
        data: JSON.stringify(commissions),
        dataType: "json",
        contentType: 'application/json; charset=utf-8',
        success: function (data) {
            if (data.Result) {
                jQuery(GRID_AGENTS).trigger('reloadGrid');
            }
            else {
                jAlert("A problem ocurred during updating", "Commissions Report");
            }
        }
    });

Now on the controller:

    [HttpPost]
    [JsonFilter(Param = "commissions", JsonDataType = typeof(List<CommissionsJs>))]
    public ActionResult SubmitCommissions(List<CommissionsJs> commissions)
    {
        var result = dosomething(commissions);
        var jsonData = new
        {
            Result = true,
            Message = "Success"
        };
        if (result < 1)
        {
            jsonData = new
            {
                Result = false,
                Message = "Problem"
            };
        }
        return Json(jsonData);
    }

Create a JsonFilter Class (thanks to JSC reference).

    public class JsonFilter : ActionFilterAttribute
    {
        public string Param { get; set; }
        public Type JsonDataType { get; set; }
        public override void OnActionExecuting(ActionExecutingContext filterContext)
        {
            if (filterContext.HttpContext.Request.ContentType.Contains("application/json"))
            {
                string inputContent;
                using (var sr = new StreamReader(filterContext.HttpContext.Request.InputStream))
                {
                    inputContent = sr.ReadToEnd();
                }
                var result = JsonConvert.DeserializeObject(inputContent, JsonDataType);
                filterContext.ActionParameters[Param] = result;
            }
        }
    }

Create another class so the filter can parse the JSON string to the actual manipulable object: This class comissionsJS are all the rows of my jqGrid.

    public class CommissionsJs
    {
        public string Amount { get; set; }

        public string CheckNumber { get; set; }

        public string Contract { get; set; }
        public string DatePayed { get; set; }
        public string DealerName { get; set; }
        public string ID { get; set; }
        public string IdAgentPayment { get; set; }
        public string Notes { get; set; }
        public string PaymentMethodName { get; set; }
        public string RowNumber { get; set; }
        public string AgentId { get; set; }
    }

I hope this example helps to illustrate how to post a complex object.

The outfile should be in binary mode.

outFile = open('output.xml', 'wb')

To avoid unnecessary duplication, I added the following to my ~/.bash_profile

case ":$PATH:" in
  *:/usr/local/bin:*) ;;     # do nothing if $PATH already contains /usr/local/bin
  *) PATH=/usr/local/bin:$PATH ;;  # in every other case, add it to the front
esac

... you are attempting to use the java.exe 1.7 executable while the HKEY_LOCAL_MACHINE\Software\JavaSoft\Java Runtime Environment > CurrentVersion registry key has the value 1.8.

The recurring theme to proposed solutions is that the error is a configuration error. The error can be solved in various different manners (e.g. reconfiguration of the users environment or removal of java executables with fingers-crossed and hope that there exists another fallback java.exe in the users %PATH% and that the fallback java.exe is the correct executable).

The correct solution depends on what you're trying to achieve: "are you trying to downgrade from jdk-8 to jdk-7? Are trying to upgrade to jdk-8? ..."

Reproduction steps

1. install jdk-7u80-windows-x64.exe

notes:

• the java.exe executable available in the users %PATH% is installed in C:\Windows\System32
• the installation does not update the users %PATH%
• the HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment > CurrentVersion string registry entry is created (among others) with the value 1.7

2. install jdk-8u191-windows-x64.exe

notes:

• the users %PATH% is updated to include C:\Program Files (x86)\Common Files\Oracle\Java\javapath as the first entry
• the the HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment > CurrentVersion string registry entries value is updated to 1.8

3. update the users %PATH% environment variable, remove C:\Program Files (x86)\Common Files\Oracle\Java\javapath

4. in a new command prompt java -version

Error: Registry key 'Software\JavaSoft\Java Runtime Environment'\CurrentVersion' has value '1.8', but '1.7' is required.

Error: could not find java.dll

Error: Could not find Java SE Runtime Environment.

Solution(s)

1. OP's solution https://stackoverflow.com/a/29769311/1423507 is a "fingers-crossed and hope that there exists a fallback java.exe in the users %PATH% and that the fallback executable is correct" approach to the error. Given the reproduction steps, removing the java.exe, javaw.exe and javaws.exe executables from C:\Windows\System32 (only in my case) will result in no longer having any java.exe present in the users %PATH% resulting in the error 'java' is not recognized as an internal or external command, operable program or batch file. which is not so much of a solution.

2. answers https://stackoverflow.com/a/35775493/1423507 and https://stackoverflow.com/a/36516620/1423507 work however you're reverting to using java.exe 1.7 (e.g. update the CurrentVersion registry key's value to match the java.exe version found in the users %PATH%).

3. make surejava.exe 1.8 is the first found in the users %PATH% (how you do that is irrelevant) i.e.:

   • update the users %PATH% to include C:\Program Files (x86)\Common Files\Oracle\Java\javapath first (ensure that the executables in that directory are correct)
   • update the users %PATH% to include the absolute path of your java binaries first (set PATH="C:\Program Files\Java\jre1.8.0_191\bin;%PATH%")
   • set java specific environment variables and update the users %PATH% with them (set JAVA_HOME="C:\Program Files\Java"; set JRE_HOME=%JAVA_HOME%\jre1.8.0_191; set PATH=%JRE_HOME%\bin;%PATH%)

This error occurs when we parse json content to model object. Json content type is string. For example: https://dotnetfiddle.net/uFClKj Some times, an api that we call may return an error. If we do not check the response status, but proceed to parse the response to model, this issue will occur.

These are the options currently documented in the tests: ctrl, shift, enter and escape. These are some valid examples of key bindings:

keydown.control.shift.enter
keydown.control.esc

You can track this here while no official docs exist, but they should be out soon.

Here is another solution, If you are using ES6 using spread operator:

var arr = [0, 21, 22, 7];

const indexOfMaxValue = arr.indexOf(Math.max(...arr));

It's a great question, but be warned that you're treading in dangerous waters here. When you're deleting code you will have to make sure you're compiling and testing often.

One great tool come to mind:

NDepend - this tool is just amazing. It takes a little while to grok, and after the first 10 minutes I think most developers just say "Screw it!" and delete the app. Once you get a good feel for NDepend, it gives you amazing insight to how your apps are coupled. Check it out: http://www.ndepend.com/. Most importantly, this tool will allow you to view methods which do not have any direct callers. It will also show you the inverse, a complete call tree for any method in the assembly (or even between assemblies).

Whatever tool you choose, it's not a task to take lightly. Especially if you're dealing with public methods on library type assemblies, as you may never know when an app is referencing them.

to set the height of table, you need to first set css property "display: block" then you can add "width/height" properties. I find this Mozilla Article a very good resource to learn how to style tables : Link

There is also the possibility to use the Vector Asset Studio in combination with Scalable Vector Graphics (SVG). Android Studio will handle the rest for you. As the official documentation says:

Vector Asset Studio helps you add material icons and import Scalable Vector Graphic (SVG) files into your app project as a drawable resource. Compared to raster images, vector drawables can reduce the size of your app and be resized without loss of image quality. They help you to more easily support different Android devices with varying screen sizes and resolutions because you can display one vector drawable on all of them.

I consider this the future approach.

Had this problem and solved typing this : C:\Program Files (x86)\Java\jdk1.7.0_51\bin\javadoc.exe

Just copy this:

    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="horizontal">
        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Your text:"/>
        <CheckBox
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:checked="true"
            />
    </LinearLayout>

Happy codding! :)

You can appendChild to document.body but not if the document hasn't been loaded. So you should put everything in:

window.onload=function(){
    //your code
}

This works or you can make appendChild to be dependent on something else like another event for eg.

As a matter of fact you can try changing the innerHTML of the document.body it works...!

I'm using Argos reporting system as a front end and Oracle in back. I just encountered this error and it was caused by a string with a double quote at the start and a single quote at the end. Replacing the double quote with a single solved the issue.

Casting pointers is usually invalid in C. There are several reasons:

1. Alignment. It's possible that, due to alignment considerations, the destination pointer type is not able to represent the value of the source pointer type. For example, if int * were inherently 4-byte aligned, casting char * to int * would lose the lower bits.

2. Aliasing. In general it's forbidden to access an object except via an lvalue of the correct type for the object. There are some exceptions, but unless you understand them very well you don't want to do it. Note that aliasing is only a problem if you actually dereference the pointer (apply the * or -> operators to it, or pass it to a function that will dereference it).

The main notable cases where casting pointers is okay are:

1. When the destination pointer type points to character type. Pointers to character types are guaranteed to be able to represent any pointer to any type, and successfully round-trip it back to the original type if desired. Pointer to void (void *) is exactly the same as a pointer to a character type except that you're not allowed to dereference it or do arithmetic on it, and it automatically converts to and from other pointer types without needing a cast, so pointers to void are usually preferable over pointers to character types for this purpose.

2. When the destination pointer type is a pointer to structure type whose members exactly match the initial members of the originally-pointed-to structure type. This is useful for various object-oriented programming techniques in C.

Some other obscure cases are technically okay in terms of the language requirements, but problematic and best avoided.

Change your model to specify what columns you want selected:

public function user() {
  return $this->belongs_to('User')->select(array('id', 'username'));
}

And don't forget to include the column you're joining on.

On Eclipse I was able to solve the above issue by following the below steps :

Right-click on the test file which you want to run, Select Run As -> Run Configurations -> Select Classpath tab -> Select to the bootstrap Entries -> Select Advanced -> Select Add library -> Select JUnit -> Next ->Select JUnit4 from the drop-down -> Finish

Then Select Apply -> Run

CLR2's System.String is mutable. StringBuilder.Append calling String.AppendInplace (private method)

CLR4's System.String is immutable. StringBuilder have Char array with chunking.

If you didn't push the update in remote then the simple solution is remove last local commit using following command: git reset HEAD^. Then add all files and commit again.

Using change event you can do something like this:

var limit = 3;
$('input.single-checkbox').on('change', function(evt) {
   if($(this).siblings(':checked').length >= limit) {
       this.checked = false;
   }
});

It has been mentioned in earlier answers that using dependency walker is the way to go, in my case (my application keeps failing with the error code), dependency walker showed a few dll that are NOT relevant!

Finally figured out that I can run profiling by going to "profile" menu and it will run the application and stop at the exact dll that's cause the problem! I found out a 32bit dll was picked because of path and fixed it.

For me the problem was invalid permissions - I was requesting "birthday" instead of "user_birthday". It's a shame the error message isn't at least minimally descriptive - just saying "permissions invalid" rather than ERROR CODE 2 would have saved me so much time.

In case you are using node.js (with express)

If you want to serve static files in node.js, you need to use a function. Add the following code to your js file:

app.use(express.static("public"));

Where app is:

const express = require("express");
const app = express();

Then create a folder called public in you project folder. (You could call it something else, this is just good practice but remember to change it from the function as well.)

Then in this file create another folder named css (and/or images file under css if you want to serve static images as well.) then add your css files to this folder.

After you add them change the stylesheet accordingly. For example if it was:

href="cssFileName.css"

and

src="imgName.png"

Make them:

href="css/cssFileName.css"
src="css/images/imgName.png"

That should work

I use numpy.fromiter to invert a 8-greyscale bitmap, yet no signs of side-effects

import Image
import numpy as np

im = Image.load('foo.jpg')
im = im.convert('L')

arr = np.fromiter(iter(im.getdata()), np.uint8)
arr.resize(im.height, im.width)

arr ^= 0xFF  # invert
inverted_im = Image.fromarray(arr, mode='L')
inverted_im.show()

I dont know if there is a canonical way, but here's my method:

• Create a xib for a ViewController
• Set the File Owner class to UIViewController
• Delete the view and add an UITableViewCell
• Set the Class of your UITableViewCell to your custom class
• Set the Identifier of your UITableViewCell
• Set the outlet of your view controller view to your UITableViewCell

And use this code:

MyCustomViewCell *cell = (MyCustomViewCell *)[_tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
  UIViewController* c = [[UIViewController alloc] initWithNibName:CellIdentifier bundle:nil];
  cell = (MyCustomViewCell *)c.view;
  [c release];
}

In your example, using

[nib objectAtIndex:0]

may break if Apple changes the order of items in the xib.

Another reason why you should avoid converting the column to varchar(max) is because you cannot create an index on a varchar(max) column.

I know how to generate random number in C++ without using any headers, compiler intrinsics or whatever.

#include <cstdio> // Just for printf
int main() {
    auto val = new char[0x10000];
    auto num = reinterpret_cast<unsigned long long>(val);
    delete[] val;
    num = num / 0x1000 % 10;
    printf("%llu\n", num);
}

I got the following stats after run for some period of time:

0: 5268
1: 5284
2: 5279
3: 5242
4: 5191
5: 5135
6: 5183
7: 5236
8: 5372
9: 5343

Looks random.

How it works:

• Modern compilers protect you from buffer overflow using ASLR (address space layout randomization).
• So you can generate some random numbers without using any libraries, but it is just for fun. Do not use ASLR like that.

Assuming SQL Server 2000, the following StackOverflow question should address your problem.

If using SQL Server 2005/2008, you can use the following code (taken from here):

select cast(replace(cast(myntext as nvarchar(max)),'find','replace') as ntext)
from myntexttable

Here's a method using display:flex:

.container {_x000D_
  height: 100%;_x000D_
  width: 100%;_x000D_
  display: flex;_x000D_
  position: fixed;_x000D_
  align-items: center;_x000D_
  justify-content: center;_x000D_
}

<div class="container">_x000D_
  <div>centered text!</div>_x000D_
</div>

Check Browser Compatability

For Picrofo EDY

It depends, if you use the ShowDialog() as a way of showing your form and to close it you use the close button instead of this.Close(). The form will not be disposed or destroyed, it will only be hidden and changes can be made after is gone. In order to properly close it you will need the Dispose() or Close() method. In the other hand, if you use the Show() method and you close it, the form will be disposed and can not be modified after.

React

For modal component in React project, the open or close of the modal, controlling browser back is a necessary action.

• The stopBrowserBack: the stop of the browser back button functionality, also get a callback function. This callback function is what you want to do:

  const stopBrowserBack = callback => {
    window.history.pushState(null, "", window.location.href);
    window.onpopstate = () => {
      window.history.pushState(null, "", window.location.href);
      callback();
    };
  };
  

• The startBrowserBack: the revival of the browser back button functionality:

  const startBrowserBack = () => {
    window.onpopstate = undefined;
    window.history.back();
  };
  

The usage in your project:

handleOpenModal = () =>
  this.setState(
    { modalOpen: true },
    () => stopBrowserBack(this.handleCloseModal)
  );

handleCloseModal = () =>
  this.setState(
    { modalOpen: false },
    startBrowserBack
  );

Pressing Shift+v would select that entire line and pressing d would delete it.

You can also use dd, which is does not require you to enter visual mode.
