Here you have example how to set the readonly attribute:

<form action="demo_form.asp">_x000D_
  Country: <input type="text" name="country" value="Norway" readonly><br>_x000D_
  <input type="submit" value="Submit">_x000D_
</form>

You can do it with built-in RegExp(pattern[, flags]) Factory Notation in js like this:

RegExp(/-(.*)/).exec("sometext-20202")[1]

in above code exec function will return an array with two elements (["-20202", "20202"]) one with hyphen(-20202) and one without hyphen(20202) , you should pick second element (index 1)

Make an effort to configure your build path. Code completion uses a lot of memory if it has to go through your whole project folder.

• Right click on your project and choose preferences.
• Choose your build path setting and remove your project folder.
• Then add only the folders where you have your source code and library code.

Yes, on a 32bit machine the maximum amount of memory usable is around 4GB. Actually, depending on the OS it might be less due to parts of the address space being reserved: On Windows you can only use 3.5GB for example.

On 64bit you can indeed address 2^64 bytes of memory. Not that you'll ever have those - but then again, a long time ago the same thing was said about ever needing more than 640kb of memory...

You can use the CURSOR_STATUS function to determine its state.

IF CURSOR_STATUS('global','myCursor')>=-1
BEGIN
 DEALLOCATE myCursor
END

It's called Padding:

myString.PadLeft(3, '0')

The default for matrix is to have 1 column. To explicitly have 0 columns, you need to write

matrix(, nrow = 15, ncol = 0)

A better way would be to preallocate the entire matrix and then fill it in

mat <- matrix(, nrow = 15, ncol = n.columns)
for(column in 1:n.columns){
  mat[, column] <- vector
}

Thymeleaf has an equivalent to <c:choose> and <c:when>: the th:switch and th:case attributes introduced in Thymeleaf 2.0.

They work as you'd expect, using * for the default case:

<div th:switch="${user.role}"> 
  <p th:case="'admin'">User is an administrator</p>
  <p th:case="#{roles.manager}">User is a manager</p>
  <p th:case="*">User is some other thing</p> 
</div>

See this for a quick explanation of syntax (or the Thymeleaf tutorials).

Use SecurityElement.Escape

using System;
using System.Security;

class Sample {
  static void Main() {
    string text = "Escape characters : < > & \" \'";
    string xmlText = SecurityElement.Escape(text);
//output:
//Escape characters : &lt; &gt; &amp; &quot; &apos;
    Console.WriteLine(xmlText);
  }
}

Below are the steps I followed to install python34 and pip

yum update -y
yum -y install yum-utils
yum -y groupinstall development
yum -y install https://centos7.iuscommunity.org/ius-release.rpm
yum makecache
yum -y install python34u  python34u-pip
python3.6 -v
echo "alias python=/usr/bin/python3.4" >> ~/.bash_profile
source ~/.bash_profile
pip3 install --upgrade pip

# if yum install python34u-pip doesnt work, try 

curl https://bootstrap.pypa.io/get-pip.py | python

Use this:

    public void ShowAllPostBackData()
    {
        if (IsPostBack)
        {
            string[] keys = Request.Form.AllKeys;
            Literal ctlAllPostbackData = new Literal();
            ctlAllPostbackData.Text = "<div class='well well-lg' style='border:1px solid black;z-index:99999;position:absolute;'><h3>All postback data:</h3><br />";
            for (int i = 0; i < keys.Length; i++)
            {
                ctlAllPostbackData.Text += "<b>" + keys[i] + "</b>: " + Request[keys[i]] + "<br />";
            }
            ctlAllPostbackData.Text += "</div>";
            this.Controls.Add(ctlAllPostbackData);
        }
    }

Super simple code using TryParse:

var value = "Active";

StatusEnum status;
if (!Enum.TryParse<StatusEnum>(value, out status))
    status = StatusEnum.Unknown;

OK, i just fixed this error.

This happens when there is an error in query or table doesn't exist.

Try debugging the query buy running it directly on phpmyadmin to confirm the validity of the mysql Query

Try the following:

Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);            
config.AppSettings.Settings[key].Value = value;
config.Save();
ConfigurationManager.RefreshSection("appSettings");

I am getting the error (...) javax.naming.NameNotFoundException: greetJndi not bound

This means that nothing is bound to the jndi name greetJndi, very likely because of a deployment problem given the incredibly low quality of this tutorial (check the server logs). I'll come back on this.

Is there any specific directory structure to deploy in JBoss?

The internal structure of the ejb-jar is supposed to be like this (using the poor naming conventions and the default package as in the mentioned link):

.
+-- greetBean.java
+-- greetHome.java
+-- greetRemote.java
+-- META-INF
    +-- ejb-jar.xml
    +-- jboss.xml

But as already mentioned, this tutorial is full of mistakes:

• there is an extra character (<enterprise-beans>] <-- HERE) in the ejb-jar.xml (!)
• a space is missing after PUBLIC in the ejb-jar.xml and jboss.xml (!!)
• the jboss.xml is incorrect, it should contain a session element instead of entity (!!!)

Here is a "fixed" version of the ejb-jar.xml:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE ejb-jar PUBLIC "-//Sun Microsystems, Inc.//DTD Enterprise JavaBeans 2.0//EN" "http://java.sun.com/dtd/ejb-jar_2_0.dtd">
<ejb-jar>
  <enterprise-beans>
    <session>
      <ejb-name>greetBean</ejb-name>
      <home>greetHome</home>
      <remote>greetRemote</remote>
      <ejb-class>greetBean</ejb-class>
      <session-type>Stateless</session-type>
      <transaction-type>Container</transaction-type>
    </session>
  </enterprise-beans>
</ejb-jar>

And of the jboss.xml:

<?xml version="1.0"?>
<!DOCTYPE jboss PUBLIC "-//JBoss//DTD JBOSS 3.2//EN" "http://www.jboss.org/j2ee/dtd/jboss_3_2.dtd">
<jboss>
  <enterprise-beans>
    <session>
      <ejb-name>greetBean</ejb-name>
      <jndi-name>greetJndi</jndi-name>
    </session>
  </enterprise-beans>
</jboss>

After doing these changes and repackaging the ejb-jar, I was able to successfully deploy it:

21:48:06,512 INFO  [Ejb3DependenciesDeployer] Encountered deployment AbstractVFSDeploymentContext@5060868{vfszip:/home/pascal/opt/jboss-5.1.0.GA/server/default/deploy/greet.jar/}

That tutorial needs significant improvement; I'd advise from staying away from roseindia.net.

Do you mean unique:

R> x = c(1,1,2,3,4,4,4)
R> x
[1] 1 1 2 3 4 4 4
R> unique(x)
[1] 1 2 3 4

You can think of an iframe as an embedded browser window that you can put on an HTML page to show another URL inside it. This URL can be totally distinct from your web site/app.

You can put an iframe in any HTML page, so you could put one inside a contentplaceholder in a webform that has a Masterpage and it will appear with whatever URL you load into it (via Javascript, or C# if you turn your iframe into a server-side control (runat='server') on the final HTML page that your webform produces when requested.

And you can load a URL into your iframe that is a .aspx page.

But - iframes have nothing to do with the ASP.net mechanism. They are HTML elements that can be made to run server-side, but they are essentially 'dumb' and unmanaged/unconnected to the ASP.Net mechanisms - don't confuse a Contentplaceholder with an iframe.

Incidentally, the use of iframes is still contentious - do you really need to use one? Can you afford the negative trade-offs associated with them e.g. lack of navigation history ...?

You can do it like this:

var list = document.getElementById("foo").getElementsByClassName("bar");
if (list && list.length > 0) {
    list[0].innerHTML = "Goodbye world!";
}

or, if you want to do it with with less error checking and more brevity, it can be done in one line like this:

document.getElementById("foo").getElementsByClassName("bar")[0].innerHTML = "Goodbye world!";

In explanation:

1. You get the element with id="foo".
2. You then find the objects that are contained within that object that have class="bar".
3. That returns an array-like nodeList, so you reference the first item in that nodeList
4. You can then set the innerHTML of that item to change its contents.

Caveats: some older browsers don't support getElementsByClassName (e.g. older versions of IE). That function can be shimmed into place if missing.

This is where I recommend using a library that has built-in CSS3 selector support rather than worrying about browser compatibility yourself (let someone else do all the work). If you want just a library to do that, then Sizzle will work great. In Sizzle, this would be be done like this:

Sizzle("#foo .bar")[0].innerHTML = "Goodbye world!";

jQuery has the Sizzle library built-in and in jQuery, this would be:

$("#foo .bar").html("Goodbye world!");

Use re.sub directly, this allows you to specify a count:

regex.sub('', url, 1)

(Note that the order of arguments is replacement, original not the opposite, as might be suspected.)

That helped me with my code.

When I tried feltering only a type of files and show them on screen by adding a condition that tests on each line.

Like this

elif command == 'ls':
    print("directory of ", ftp.pwd())
    data = []
    ftp.dir(data.append)

    for line in data:
        x = line.split(".")
        formats=["gz", "zip", "rar", "tar", "bz2", "xz"]
        if x[-1] in formats:
            print ("-", line)

in the manifest:

<activity android:name=".activity.MainActivity"
        android:screenOrientation="portrait"
        tools:ignore="LockedOrientationActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

or : in the MainActivity

@SuppressLint("SourceLockedOrientationActivity")
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

I got same error and it was due to older Lombok version. Check and update your Lombok version, Changes in Lombok

v1.18.4 - Many improvements for lombok's JDK10/11 support.

You could create a YAML file and read it in using PyYaml.

Step 1: Create a YAML file, "employment.yml":

new jersey:
  mercer county:
    pumbers: 3
    programmers: 81
  middlesex county:
    salesmen: 62
    programmers: 81
new york:
  queens county:
    plumbers: 9
    salesmen: 36

Step 2: Read it in Python

import yaml
file_handle = open("employment.yml")
my_shnazzy_dictionary = yaml.safe_load(file_handle)
file_handle.close()

and now my_shnazzy_dictionary has all your values. If you needed to do this on the fly, you can create the YAML as a string and feed that into yaml.safe_load(...).

For Ubuntu users: First You need to install mailutils

sudo apt-get install mailutils

Setup an email server, if you are using gmail or smtp. follow this link. then use this command to send email.

echo "this is a test mail" | mail -s "Subject of mail" [email protected]

In case you are using gmail and still you are getting some authentication error then you need to change setting of gmail:

Turn on Access for less secure apps from here

UNIVERSAL ADB DRIVER

I have thesame issue before but i solved it easily by just following this steps:

*connect your android phone in a debugging mode (to enable debugging mode goto settings scroll down About Phone scroll down tap seven times Build Number and it will automatically enable developer option turn on developer options and check USB debugging)

download Universal ADB Driver Installer

*choose Adb Driver Installer (Universal)

*install it *it will automatically detect your android device(any kind of brand) *chose the device and install

I have used these convenience methods before:

- (CGRect)getScreenFrameForCurrentOrientation {
    return [self getScreenFrameForOrientation:[UIApplication sharedApplication].statusBarOrientation];
}

- (CGRect)getScreenFrameForOrientation:(UIInterfaceOrientation)orientation {

    CGRect fullScreenRect = [[UIScreen mainScreen] bounds];

    // implicitly in Portrait orientation.
    if (UIInterfaceOrientationIsLandscape(orientation)) {
      CGRect temp = CGRectZero;
      temp.size.width = fullScreenRect.size.height;
      temp.size.height = fullScreenRect.size.width;
      fullScreenRect = temp;
    }

    if (![[UIApplication sharedApplication] statusBarHidden]) {
      CGFloat statusBarHeight = 20; // Needs a better solution, FYI statusBarFrame reports wrong in some cases..
      fullScreenRect.size.height -= statusBarHeight;
    }

    return fullScreenRect;
} 

The follows is often used:

select field_SQ.nextval from dual;
select field_SQ.currval from DUAL;

However the following is able to change the sequence to what you expected. The 1 can be an integer (negative or positive)

alter sequence field_SQ increment by 1 minvalue 0

You don't need to use the asterisk to accept a list.

Simply give the argument a name in the definition, and pass in a list like

def takes_list(a_list):
    for item in a_list:
         print item

AFAIK, there is no a interactive option for output to file, there is a previous SO question related with this: Printing mongodb shell output to File

However, you can log all the shell session if you invoked the shell with tee command:

$ mongo | tee file.txt
MongoDB shell version: 2.4.2
connecting to: test
> printjson({this: 'is a test'})
{ "this" : "is a test" }
> printjson({this: 'is another test'})
{ "this" : "is another test" }
> exit
bye

Then you'll get a file with this content:

MongoDB shell version: 2.4.2
connecting to: test
> printjson({this: 'is a test'})
{ "this" : "is a test" }
> printjson({this: 'is another test'})
{ "this" : "is another test" }
> exit
bye

To remove all the commands and keep only the json output, you can use a command similar to:

tail -n +3 file.txt | egrep -v "^>|^bye" > output.json

Then you'll get:

{ "this" : "is a test" }
{ "this" : "is another test" }

sometime you missed some file like I missed my one file rt.java so better to check yours .........

C:\Program Files\Java\jdk1.8.0_112\jre\lib

It is possible to print what Python lines are executed (thanks Geo!). This has any number of applications, for example, you could modify it to check when particular functions are called or add something like ## make it only track particular lines.

code.interact takes you into a interactive console

import code; code.interact(local=locals())

If you want to be able to easily access your console history look at: "Can I have a history mechanism like in the shell?" (will have to look down for it).

Auto-complete can be enabled for the interpreter.

With the new v7 support library (21.0.0) the name in R.dimen has changed to @dimen/abc_action_bar_default_height_material.

When upgrading from a previous version of the support lib you should therefore use that value as the actionbar's height

Make sure you have the prerequisite, a JVM (http://wiki.eclipse.org/Eclipse/Installation#Install_a_JVM) installed.

This will be a JRE and JDK package.

There are a number of sources which includes: http://www.oracle.com/technetwork/java/javase/downloads/index.html.

Whenever possible one should avoid culture specific date/time literals.

There are some secure formats to provide a date/time as literal:

All examples for 2016-09-15 17:30:00

ODBC (my favourite, as it is handled as the real type immediately)

• {ts'2016-09-15 17:30:00'} --Time Stamp
• {d'2016-09-15'} --Date only
• {t'17:30:00'} --Time only

ISO8601 (the best for everywhere)

• '2016-09-15T17:30:00' --be aware of the T in the middle!

Unseperated (tiny risk to get misinterpreted as number)

• '20160915' --only for pure date

Good to keep in mind: Invalid dates tend to show up with strange errors

• There is no 31st of June or 30th of February...

One more reason for strange conversion errors: Order of execution!

SQL-Server is well know to do things in an order of execution one might not have expected. Your written statement looks like the conversion is done before some type related action takes place, but the engine decides - why ever - to do the conversion in a later step.

Here is a great article explaining this with examples: Rusano.com: "t-sql-functions-do-no-imply-a-certain-order-of-execution" and here is the related question.

It appears you may just have missed the "messages" property in the data, so the loop is likely iterating the root Object rather than the Array:

for (var key in data.messages) {
    var obj = data.messages[key];
    // ...
}

Unless data was set to messages before the given snippet.

Though, you should consider changing that to a normal for loop for the Array:

for (var i = 0, l = data.messages.length; i < l; i++) {
    var obj = data.messages[i];
    // ...
}

Actually your $product has no data because the Eloquent model returns NULL. It's probably because you have used whereOwnerAndStatus which seems wrong and if there were data in $product then it would not work in your first example because get() returns a collection of multiple models but that is not the case. The second example throws error because foreach didn't get any data. So I think it should be something like this:

$owner = Input::get('owner');
$count = Input::get('count');
$products = Product::whereOwner($owner, 0)->take($count)->get();

Further you may also make sure if $products has data:

if($product) {
    return View:make('viewname')->with('products', $products);
}

Then in the view:

foreach ($products as $product) {
    // If Product has sku (collection object, probably related models)
    foreach ($product->sku as $sku) {
        // Code Here        
    }
}

Let's say that I want to create the following URL:

https://www.myawesomesite.com/turtles/types?type=1&sort=relevance#section-name

To build this with the Uri.Builder I would do the following.

Uri.Builder builder = new Uri.Builder();
builder.scheme("https")
    .authority("www.myawesomesite.com")
    .appendPath("turtles")
    .appendPath("types")
    .appendQueryParameter("type", "1")
    .appendQueryParameter("sort", "relevance")
    .fragment("section-name");
String myUrl = builder.build().toString();

import java.util.Random;

$(selector).change()

.change()

.trigger("change")

Longer slower alternative, better for abstraction.

.trigger("change")

$(selector).trigger("change")

  longitude = longitude + prevLongitude

    longitude = longitude - 2*pi

  prevLongitude = longitude
  if (longitude > pi):
    longitude = longitude - 2*pi

  latitude = arccos(zInc) - pi/2
  vxyz[index] = array([ (cos(latitude) * cos(longitude)) ,
                        (cos(latitude) * sin(longitude)), 
                        sin(latitude)])

I recently came up with a one-line solution that accomplishes exactly this for a JS challenge on Scrimba (below).

ES6+

const getPrimes=num=>Array(num-1).fill().map((e,i)=>2+i).filter((e,i,a)=>a.slice(0,i).every(x=>e%x!==0));

< ES6

function getPrimes(num){return ",".repeat(num).slice(0,-1).split(',').map(function(e,i){return i+1}).filter(function(e){return e>1}).filter(function(x){return ",".repeat(x).slice(0,-1).split(',').map(function(f,j){return j}).filter(function(e){return e>1}).every(function(e){return x%e!==0})})};

This is the logic explained:

1. First, the function builds an array of all numbers leading up to the desired number (in this case, 100) via the .repeat() function using the desired number (100) as the repeater argument and then mapping the array to the indexes+1 to get the range of numbers from 0 to that number (0-100). A bit of string splitting and joining magic going on here. I'm happy to explain this step further if you like.

2. We exclude 0 and 1 from the array as they should not be tested for prime, lest they give a false positive. Neither are prime. We do this using .filter() for only numbers > 1 (= 2).

3. Now, we filter our new array of all integers between 2 and the desired number (100) for only prime numbers. To filter for prime numbers only, we use some of the same magic from our first step. We use .filter() and .repeat() once again to create a new array from 2 to each value from our new array of numbers. For each value's new array, we check to see if any of the numbers = 2 and < that number are factors of the number. We can do this using the .every() method paired with the modulo operator % to check if that number has any remainders when divided by any of those values between 2 and itself. If each value has remainders (x%e!==0), the condition is met for all values from 2 to that number (but not including that number, i.e.: [2,99]) and we can say that number is prime. The filter functions returns all prime numbers to the uppermost return, thereby returning the list of prime values between 2 and the passed value.

As an example, using one of these functions I've added above, returns the following:

getPrimes(100);
// => [2,3,5,7,11,13,17,19,23,29,31,37,41,43,47,53,59,61,67,71,73,79,83,89,97]

It had happened to me when I replace the default value with a new dynamic value. But, somehow your code may be dependent on that default value. So try keeping a constant with default value stored somewhere to fallback.

const defVal = 'abcd';
String dynVal = defVal;

// dropdown list whose value is dynVal that keeps changing with onchanged
// when rebuilding or setState((){})

dynVal = defVal;
// rebuilding here...

Use LINQ:

Datagridview1.Columns.Cast<DataGridViewColumn>().ToList().ForEach(f => f.SortMode = DataGridViewColumnSortMode.NotSortable);

GUI is a high level abstraction of capability, so almost everything from XOrg server to OpenGL is ported cross-platform, including for Windows platform. But if by GUI API you mean *nix graphics API then you might be wandering around "Direct Rendering Infrastructure".

You should always use audio/mpeg, because firefox cannot play audio/mpeg3 files

The answer is to use Welford's algorithm, which is very clearly defined after the "naive methods" in:

• Wikipedia: Algorithms for calculating variance

It's more numerically stable than either the two-pass or online simple sum of squares collectors suggested in other responses. The stability only really matters when you have lots of values that are close to each other as they lead to what is known as "catastrophic cancellation" in the floating point literature.

You might also want to brush up on the difference between dividing by the number of samples (N) and N-1 in the variance calculation (squared deviation). Dividing by N-1 leads to an unbiased estimate of variance from the sample, whereas dividing by N on average underestimates variance (because it doesn't take into account the variance between the sample mean and the true mean).

I wrote two blog entries on the topic which go into more details, including how to delete previous values online:

• Computing Sample Mean and Variance Online in One Pass
• Deleting Values in Welford’s Algorithm for Online Mean and Variance

You can also take a look at my Java implement; the javadoc, source, and unit tests are all online:

• Javadoc: stats.OnlineNormalEstimator
• Source: stats.OnlineNormalEstimator.java
• JUnit Source: test.unit.stats.OnlineNormalEstimatorTest.java
• LingPipe Home Page

You can use Substring:

string b = a.Substring(0,3);

When encrypting, you use their public key to write a message and they use their private key to read it.

When signing, you use your private key to write message's signature, and they use your public key to check if it's really yours.

I want to use my private key to generate messages so only I can possibly be the sender.

I want my public key to be used to read the messages and I do not care who reads them

This is signing, it is done with your private key.

I want to be able to encrypt certain information and use it as a product key for my software.

I only care that I am the only one who can generate these.

If you only need to know it to yourself, you don't need to mess with keys to do this. You may just generate random data and keep it in a database.

But if you want people to know that the keys are really yours, you need to generate random data, keep in it a database AND sign it with your key.

I would like to include my public key in my software to decrypt/read the signature of the key.

You'll probably need to purchase a certificate for your public key from a commercial provider like Verisign or Thawte, so that people may check that no one had forged your software and replaced your public key with theirs.

My default 3306 port was in use, so Ive changed it to 8111, then I had this error. Ive fixed it by adding

$cfg['Servers'][$i]['port'] = '8111';

into config.inc.php . If you are using different port number then set yours.

The semantics of setTimeout are roughly the same as in a web browser: the timeout arg is a minimum number of ms to wait before executing, not a guarantee. Furthermore, passing 0, a non-number, or a negative number, will cause it to wait a minimum number of ms. In Node, this is 1ms, but in browsers it can be as much as 50ms.

The reason for this is that there is no preemption of JavaScript by JavaScript. Consider this example:

setTimeout(function () {
  console.log('boo')
}, 100)
var end = Date.now() + 5000
while (Date.now() < end) ;
console.log('imma let you finish but blocking the event loop is the best bug of all TIME')

The flow here is:

1. schedule the timeout for 100ms.
2. busywait for 5000ms.
3. return to the event loop. check for pending timers and execute.

If this was not the case, then you could have one bit of JavaScript "interrupt" another. We'd have to set up mutexes and semaphors and such, to prevent code like this from being extremely hard to reason about:

var a = 100;
setTimeout(function () {
  a = 0;
}, 0);
var b = a; // 100 or 0?

The single-threadedness of Node's JavaScript execution makes it much simpler to work with than most other styles of concurrency. Of course, the trade-off is that it's possible for a badly-behaved part of the program to block the whole thing with an infinite loop.

Is this a better demon to battle than the complexity of preemption? That depends.

imgtag.group(0) or imgtag.group(). This returns the entire match as a string. You are not capturing anything else either.

http://docs.python.org/release/2.5.2/lib/match-objects.html

I think the following is equivalent to the safe navigation operator, although a bit longer:

var streetName = user && user.address && user.address.street;

streetName will then be either the value of user.address.street or undefined.

If you want it to default to something else you can combine with the above shortcut or to give:

var streetName = (user && user.address && user.address.street) || "Unknown Street";

This is what I do for floats. Although, honestly, I'm not sure which versions it works for - I'm using 2.7:

my_number = 4385893.382939491

my_string = '{:0,.2f}'.format(my_number)

Returns: 4,385,893.38

Update: I recently had an issue with this format (couldn't tell you the exact reason), but was able to fix it by dropping the 0:

my_string = '{:,.2f}'.format(my_number)

Catch the base exception 'Exception'

   try { 
         //some code
   } catch (Exception e) {
        //catches exception and all subclasses 
   }

Try.

<ScrollView onScroll={this.handleScroll} />

And then:

handleScroll: function(event: Object) {
 console.log(event.nativeEvent.contentOffset.y);
},

If you are running webpack-dev-server in a container and are sending requests to it via its container name, you will get this error. To allow requests from other containers on the same network, simply provide the container name (or whatever name is used to resolve the container) using the --public option. This is better than disabling the security check entirely.

In my case, I was running webpack-dev-server in a container named assets with docker-compose. I changed the start command to this:

webpack-dev-server --mode development --host 0.0.0.0 --public assets

And the other container was now able to make requests via http://assets:5000.

I don't think a message box is the best way to go with this as you would need the VB code running in a loop to check the cell contents, or unless you plan to run the macro manually. In this case I think it would be better to add conditional formatting to the cell to change the background to red (for example) if the value exceeds the upper limit.

sudo netstat -lpn |grep :'3000'

3000 is port i was looking for, After first command you will have Process ID for that port

kill -9 1192

in my case 1192 was process Id of process running on 3000 PORT use -9 for Force kill the process

In IE I just use a class "normal_ol" for styling an ol list and made some modifications shown below:

previous code: ol.normal_ol { float:left; padding:0 0 0 25px; margin:0; width:500px;} ol.normal_ol li{ font:normal 13px/20px Arial; color:#4D4E53; float:left; width:100%;}

modified code: ol.normal_ol { float:left; padding:0 0 0 25px; margin:0;} ol.normal_ol li{ font:normal 13px/20px Arial; color:#4D4E53; }

My dictionary is of this format:

addr_bk = {
    'person': [
        {'name': 'Andrew', 'id': 123, 'email': '[email protected]',
         'phone': [{'type': 2, 'number': '633311122'},
                   {'type': 0, 'number': '97788665'}]
        },
        {'name': 'Tom', 'id': 456,
         'phone': [{'type': 0, 'number': '91122334'}]}, 
        {'name': 'Jack', 'id': 7788, 'email': '[email protected]'}
    ]
}

As can be seen, I have nested dictionaries and list of dicts. This is because the addr_bk was decoded from protocol buffer data that converted to a python dict using lwpb.codec. There are optional field (e.g. email => where key may be unavailable) and repeated field (e.g. phone => converted to list of dict).

I tried all the above proposed solutions. Some doesn't handle the nested dictionaries well. Others cannot print the object details easily.

Only the solution, dict2obj(dict) by Dawie Strauss, works best.

I have enhanced it a little to handle when the key cannot be found:

# Work the best, with nested dictionaries & lists! :)
# Able to print out all items.
class dict2obj_new(dict):
    def __init__(self, dict_):
        super(dict2obj_new, self).__init__(dict_)
        for key in self:
            item = self[key]
            if isinstance(item, list):
                for idx, it in enumerate(item):
                    if isinstance(it, dict):
                        item[idx] = dict2obj_new(it)
            elif isinstance(item, dict):
                self[key] = dict2obj_new(item)

    def __getattr__(self, key):
        # Enhanced to handle key not found.
        if self.has_key(key):
            return self[key]
        else:
            return None

Then, I tested it with:

# Testing...
ab = dict2obj_new(addr_bk)

for person in ab.person:
  print "Person ID:", person.id
  print "  Name:", person.name
  # Check if optional field is available before printing.
  if person.email:
    print "  E-mail address:", person.email

  # Check if optional field is available before printing.
  if person.phone:
    for phone_number in person.phone:
      if phone_number.type == codec.enums.PhoneType.MOBILE:
        print "  Mobile phone #:",
      elif phone_number.type == codec.enums.PhoneType.HOME:
        print "  Home phone #:",
      else:
        print "  Work phone #:",
      print phone_number.number

This doesn't exactly answer the question but for anyone using AngularJS trying to achieve this, the answer is slightly different. And actually the normal answer won't work (at least it didn't for me).

Your html will look pretty similar to the normal radio button:

<input type='radio' name='group' ng-model='mValue' value='first' />First
<input type='radio' name='group' ng-model='mValue' value='second' /> Second

In your controller you'll have declared the mValue that is associated with the radio buttons. To have one of these radio buttons preselected, assign the $scope variable associated with the group to the desired input's value:

$scope.mValue="second"

This makes the "second" radio button selected on loading the page.

EDIT: Since AngularJS 2.x

The above approach does not work if you're using version 2.x and above. Instead use ng-checked attribute as follows:

<input type='radio' name='gender' ng-model='genderValue' value='male' ng-checked='genderValue === male'/>Male
<input type='radio' name='gender' ng-model='genderValue' value='female' ng-checked='genderValue === female'/> Female

You simply need to use a media query in CSS to accomplish this.

@media (max-width: 1026px) {
    #fadeshow1 { display: none; }
}

Unfortunately some browsers do not support @media (looking at you IE8 and below). In those cases, you have a few options, but the most common is Respond.js which is a lightweight polyfill for min/max-width CSS3 Media Queries.

<!--[if lt IE 9]>
    <script src="respond.min.js"></script>
<![endif]-->

This will allow your responsive design to function in those old versions of IE.

I wrote these classes which served me well. It's simple yet pragmatic.

Could you try a newer plugin; on the maven site:

<version>3.0</version>

I saw the following too:

<compilerVersion>1.7</compilerVersion>

remove leading and trailing white space in 2nd column

awk 'BEGIN{FS=OFS=","}{gsub(/^[ \t]+/,"",$2);gsub(/[ \t]+$/,"",$2)}1' input.txt

another way by one gsub:

awk 'BEGIN{FS=OFS=","} {gsub(/^[ \t]+|[ \t]+$/, "", $2)}1' infile

It is not possible because they are executed in different environments (JSP at server side, JavaScript at client side). So they are not executed in the sequence you see in your code.

var val1 = document.getElementById('userName').value; 

<c:set var="user" value=""/>  // how do i set val1 here? 

Here JSTL code is executed at server side and the server sees the JavaScript/Html codes as simple texts. The generated contents from JSTL code (if any) will be rendered in the resulting HTML along with your other JavaScript/HTML codes. Now the browser renders HTML along with executing the Javascript codes. Now remember there is no JSTL code available for the browser.

Now for example,

<script type="text/javascript">
<c:set var="message" value="Hello"/> 
var message = '<c:out value="${message}"/>';
</script>

Now for the browser, this content is rendered,

<script type="text/javascript">
var message = 'Hello';
</script>

Hope this helps.

ImageButton can't have text (or, at least, android:text isn't listed in its attributes).

The Trick is:

It looks like you need to use Button (and look at drawableTop or setCompoundDrawablesWithIntrinsicBounds(int,int,int,int)).

this can be achieved using below...

 List<String> unavailable = list1.stream()
                            .filter(e -> !list2.contains(e))
                            .collect(Collectors.toList());

I think you should use, instead of document.write, DOM JavaScript API like document.createElement, .createTextNode, .appendChild and similar. Safe and almost cross browser.

ihunger's outerHTML is not cross browser, it's IE only.

Best way is to use variable.

var style1 = {
   'font-size' : '10px',
   'width' : '30px',
   'height' : '10px'
};
$("#message").css(style1);

Just a friendly reminder if you have files locally that aren't in github and yet your git status says

Your branch is up to date with 'origin/master'. nothing to commit, working tree clean

It can happen if the files are in .gitignore

Try running

cat .gitignore 

and seeing if these files show up there. That would explain why git doesn't want to move them to the remote.

Rather than use lookahead and other crazy regex, just pull out the quotes first. That is, for every quote grouping, replace that grouping with __IDENTIFIER_1 or some other indicator, and map that grouping to a map of string,string.

After you split on comma, replace all mapped identifiers with the original string values.

Do you know the length of your prefix and suffix? In your case:

result=$(echo $string | cut -c5- | rev | cut -c3- | rev)

Or more general:

result=$(echo $string | cut -c$((${#prefix}+1))- | rev | cut -c$((${#suffix}+1))- | rev)

But the solution from Adrian Frühwirth is way cool! I didn't know about that!

Found the issue with Android X device.

For Android API 28 and above

In network_security_config.xml with cleartextTrafficPermitted="true"

<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
  <domain-config cleartextTrafficPermitted="true">
    ....
  </domain-config>
</network-security-config>

Then, reload JS

If you want to redirect from a button in the View you could use:

@Html.ActionLink("Back to previous page", null, null, null, new { href = Request.UrlReferrer})

You say it's not working. What are you expecting to happen?

There's no way of getting the data out of a FormData object; it's just intended for you to use to send data along with an XMLHttpRequest object (for the send method).

Update almost five years later: In some newer browsers, this is no longer true and you can now see the data provided to FormData in addition to just stuffing data into it. See the accepted answer for more info.

This is based on the assumption that you're getting an error about the date format, such as an invalid month value or non-numeric character when numeric expected.

Dates stored in the database do not have formats. When you query the date your client is formatting the date for display, as 4/16/2011. Normally the same date format is used for selecting and updating dates, but in this case they appear to be different - so your client is apparently doing something more complicated that SQL*Plus, for example.

When you try to update it it's using a default date format model. Because of how it's displayed you're assuming that is MM/DD/YYYY, but it seems not to be. You could find out what it is, but it's better not to rely on the default or any implicit format models at all.

Whether that is the problem or not, you should always specify the date model:

UPDATE PASOFDATE SET ASOFDATE = TO_DATE('11/21/2012', 'MM/DD/YYYY');

Since you aren't specifying a time component - all Oracle DATE columns include a time, even if it's midnight - you could also use a date literal:

UPDATE PASOFDATE SET ASOFDATE = DATE '2012-11-21';

You should maybe check that the current value doesn't include a time, though the column name suggests it doesn't.

If you're doing this at any sort of a frequency, heck even on a schedule, I would absolutely, unequivocally never use a DML statement. The cost of writing to the transaction log is just to high, and setting the entire database into SIMPLE recovery mode to truncate one table is ridiculous.

The best way, is unfortunately the hard or laborious way. That being:

• Drop constraints
• Truncate table
• Re-create constraints

My process for doing this involves the following steps:

1. In SSMS right-click on the table in question, and select View Dependencies
2. Take note of the tables referenced (if any)
3. Back in object explorer, expand the Keys node and take note of the foreign keys (if any)
4. Start scripting (drop / truncate / re-create)

Scripts of this nature should be done within a begin tran and commit tran block.

I'm not familiar with the specific issue, but you could stick a div, etc inside the td and set overflow on that.

Tracemalloc module was integrated as a built-in module starting from Python 3.4, and appearently, it's also available for prior versions of Python as a third-party library (haven't tested it though).

This module is able to output the precise files and lines that allocated the most memory. IMHO, this information is infinitly more valuable than the number of allocated instances for each type (which ends up being a lot of tuples 99% of the time, which is a clue, but barely helps in most cases).

I recommend you use tracemalloc in combination with pyrasite. 9 times out of 10, running the top 10 snippet in a pyrasite-shell will give you enough information and hints to to fix the leak within 10 minutes. Yet, if you're still unable to find the leak cause, pyrasite-shell in combination with the other tools mentioned in this thread will probably give you some more hints too. You should also take a look on all the extra helpers provided by pyrasite (such as the memory viewer).

If you want to force the issue, you can do:

git reset --hard c14809fafb08b9e96ff2879999ba8c807d10fb07

send you back to how your git clone looked like at the time of the checkin

I was also getting the same error --> "[PDOException] could not find driver "

I realized that the php was pointing to /usr/bin/php instead of the lampp /opt/lampp/bin/php so i simply created and alias

alias php="/opt/lampp/bin/php"

also had to make update to the .env file to ensure the database access credentials were updated.

And guess what, it Worked!

Check the 'minSdkVersion' in your build.gradle

The default project creates it with the latest API, so if you're phone is not yet up-dated (e.g. minSdkVersion 21), which is probably your case.

Make sure the minSdkVersion value matches with the device API version or if the device has a higher one.

Example:

defaultConfig {
    applicationId 'xxxxxx'
    minSdkVersion 16
    targetSdkVersion 21
    versionCode 1
    versionName "1.0"
}

you can also do that in a directive, if you want to remove the previous class and add a new class

    .directive('toggleClass', function() {
    return {
        restrict: 'A',
        link: function(scope, element, attrs) {
            element.bind('click', function() {
                if(element.attr("class") == "glyphicon glyphicon-pencil") {
                    element.removeClass("glyphicon glyphicon-pencil");
                    element.addClass(attrs.toggleClass);
                } else {
                    element.removeClass("glyphicon glyphicon-ok");
                    element.addClass("glyphicon glyphicon-pencil");
                }
            });
        }
    };
});

and in your template:

<i class="glyphicon glyphicon-pencil" toggle-class="glyphicon glyphicon-ok"></i>

Try this, its working in FF

body,
input,
select,
button {
 font-family: Arial,Helvetica,sans-serif;
 font-size: 14px;
}

I was having similar problem and

var dataObj = JSON.parse(data);

console.log(dataObj[0].category); //will return Damskie
console.log(dataObj[1].category); //will return Meskie

This solved my problem. Thanks Selvakumar Arumugam

Those look much like Bonjour / mDNS requests to me. Those packets use multicast IP address 224.0.0.251 and port 5353.

The most likely source for this is Apple iTunes, which comes pre-installed on Mac computers (and is a popular install on Windows machines as well). Apple iTunes uses it to discover other iTunes-compatible devices in the same WiFi network.

mDNS is also used (primarily by Apple's Mac and iOS devices) to discover mDNS-compatible devices such as printers on the same network.

If this is a Linux box instead, it's probably the Avahi daemon then. Avahi is ZeroConf/Bonjour compatible and installed by default, but if you don't use DNS-SD or mDNS, it can be disabled.

To see default collation of the database:

USE db_name;
SELECT @@character_set_database, @@collation_database;

To see collation of the table:

SHOW TABLE STATUS where name like 'table_name';

To see collation of the columns:

SHOW FULL COLUMNS FROM table_name;

To see the default character set of a table

SHOW CREATE TABLE table_name;

Also, there was just a typo in your original post.

'min:2|max5' should have been 'min:2|max:5'.
Notice the ":" for the "max" rule.

Simply saying, Java context means Java native methods all together.

In next Java code two lines of code needs context: // (1) and // (2)

import java.io.*;

public class Runner{
    public static void main(String[] args) throws IOException { // (1)           
        File file = new File("D:/text.txt");
        String text = "";
        BufferedReader reader = new BufferedReader(new FileReader(file));
        String line;
        while ((line = reader.readLine()) != null){ // (2)
            text += line;
        }
        System.out.println(text);
    }
}

(1) needs context because is invoked by Java native method private native void java.lang.Thread.start0();

(2) reader.readLine() needs context because invokes Java native method public static native void java.lang.System.arraycopy(Object src, int srcPos, Object dest, int destPos, int length);

PS.

That is what BalusC is sayed about pattern Facade more strictly.

I generally store my macros in xlam add-ins separately from my workbooks so I wanted to open a workbook and then run a macro stored separately.

Since this required a VBS Script, I wanted to make it "portable" so I could use it by passing arguments. Here is the final script, which takes 3 arguments.

• Full Path to Workbook
• Macro Name
• [OPTIONAL] Path to separate workbook with Macro

I tested it like so:

"C:\Temp\runmacro.vbs" "C:\Temp\Book1.xlam" "Hello"

"C:\Temp\runmacro.vbs" "C:\Temp\Book1.xlsx" "Hello" "%AppData%\Microsoft\Excel\XLSTART\Book1.xlam"

runmacro.vbs:

Set args = Wscript.Arguments

ws = WScript.Arguments.Item(0)
macro = WScript.Arguments.Item(1)
If wscript.arguments.count > 2 Then
 macrowb= WScript.Arguments.Item(2)
End If

LaunchMacro

Sub LaunchMacro() 
  Dim xl
  Dim xlBook  

  Set xl = CreateObject("Excel.application")
  Set xlBook = xl.Workbooks.Open(ws, 0, True)
  If wscript.arguments.count > 2 Then
   Set macrowb= xl.Workbooks.Open(macrowb, 0, True)
  End If
  'xl.Application.Visible = True ' Show Excel Window
  xl.Application.run macro
  'xl.DisplayAlerts = False  ' suppress prompts and alert messages while a macro is running
  'xlBook.saved = True ' suppresses the Save Changes prompt when you close a workbook
  'xl.activewindow.close
  xl.Quit

End Sub 

Building on the solution provided I thought it might be helpful to show an example passing your own custom data object (which I've referenced here as 'message' as per question).

Class A (sender):

YourDataObject *message = [[YourDataObject alloc] init];
// set your message properties
NSDictionary *dict = [NSDictionary dictionaryWithObject:message forKey:@"message"];
[[NSNotificationCenter defaultCenter] postNotificationName:@"NotificationMessageEvent" object:nil userInfo:dict];

Class B (receiver):

- (void)viewDidLoad
{
    [super viewDidLoad];
    [[NSNotificationCenter defaultCenter]
     addObserver:self selector:@selector(triggerAction:) name:@"NotificationMessageEvent" object:nil];
}

#pragma mark - Notification
-(void) triggerAction:(NSNotification *) notification
{
    NSDictionary *dict = notification.userInfo;
    YourDataObject *message = [dict valueForKey:@"message"];
    if (message != nil) {
        // do stuff here with your message data
    }
}

A .pl is a single script.

In .pm (Perl Module) you have functions that you can use from other Perl scripts:

A Perl module is a self-contained piece of Perl code that can be used by a Perl program or by other Perl modules. It is conceptually similar to a C link library, or a C++ class.

You don't need jquery in order to do that.

var placeHolder="name";
var res=name.substr(name.indexOf(placeHolder) + placeHolder.length);

You have to go through the collection from the last item to the first. this code is in vb

for i as integer= list.items.count-1 to 0 step -1
....
list.items.removeat(i)
next

<script>
var jq=jQuery.noConflict();
(function ($) 
    {
    function nameoffunction()
    {
        // Set your code here!!
    }

    $(document).ready(readyFn); 
    })(jQuery);

now use jq in place of jQuery

Of course the best approach is to use the ever-more-supported <input type="search" />.

Anyway for a bit of coding fun I thought that it could be achieved also using the form's reset button, and this is the working result (it is worth noting that you cannot have other inputs in the form but the search field with this approach, or the reset button will erase them too), no javascript needed:

form{
    position: relative;
    width: 200px;
}

form input {
    width: 100%;
    padding-right: 20px;
    box-sizing: border-box;
}

form input:placeholder-shown + button{
  opacity: 0;
  pointer-events: none;
} 

form button {
    position: absolute;
    border: none;
    display: block;
    width: 15px;
    height: 15px;
    line-height: 16px;
    font-size: 12px;
    border-radius: 50%;
    top: 0;
    bottom: 0;
    right: 5px;
    margin: auto;
    background: #ddd;
    padding: 0;
    outline: none;
    cursor: pointer;
    transition: .1s;
}

<form>
        <input type="text" placeholder=" " />
        <button type="reset">&times;</button>
</form>

Something worth noting is that INSERT IGNORE will still increment the primary key whether the statement was a success or not just like a normal INSERT would.

This will cause gaps in your primary keys that might make a programmer mentally unstable. Or if your application is poorly designed and depends on perfect incremental primary keys, it might become a headache.

Look into innodb_autoinc_lock_mode = 0 (server setting, and comes with a slight performance hit), or use a SELECT first to make sure your query will not fail (which also comes with a performance hit and extra code).

There is a simple, easy and better approach, if we need to change only the color of hamburger/back icon.

It is better as it changes color only of desired icon, whereas colorControlNormal and android:textColorSecondary might affect other childviews of toolbar as well.

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="drawerArrowStyle">@style/DrawerArrowStyle</item>
</style>

<style name="DrawerArrowStyle" parent="Widget.AppCompat.DrawerArrowToggle">
    <item name="spinBars">true</item>
    <item name="color">@android:color/white</item>
</style>

You can use this method.

    public static File getRobotCacheFile(Context context) throws IOException {
        File cacheFile = new File(context.getCacheDir(), "robot.png");
        try {
            InputStream inputStream = context.getAssets().open("robot.png");
            try {
                FileOutputStream outputStream = new FileOutputStream(cacheFile);
                try {
                    byte[] buf = new byte[1024];
                    int len;
                    while ((len = inputStream.read(buf)) > 0) {
                        outputStream.write(buf, 0, len);
                    }
                } finally {
                    outputStream.close();
                }
            } finally {
                inputStream.close();
            }
        } catch (IOException e) {
            throw new IOException("Could not open robot png", e);
        }
        return cacheFile;
    }

You should never use InputStream.available() in such cases. It returns only bytes that are buffered. Method with .available() will never work with bigger files and will not work on some devices at all.

In Kotlin (;D):

@Throws(IOException::class)
fun getRobotCacheFile(context: Context): File = File(context.cacheDir, "robot.png")
    .also {
        it.outputStream().use { cache -> context.assets.open("robot.png").use { it.copyTo(cache) } }
    }

 $('elements-to-match').click(function(){
        alert("The id is "+ this.id );
    });

no need to wrap it in a jquery object

If g++ still gives error Try using:

g++ file.c -lstdc++

Look at this post: What is __gxx_personality_v0 for?

Make sure -lstdc++ is at the end of the command. If you place it at the beginning (i.e. before file.c), you still can get this same error.

If you're trying to copy the array:

array2 = array[:]

I second jdk's answer: any public static member of any class of your application can be considered as a "global variable".

However, do note that this is an ASP.NET application, and as such, it's a multi-threaded context for your global variables. Therefore, you should use some locking mechanism when you update and/or read the data to/from these variables. Otherwise, you might get your data in a corrupted state.

So, I would like to explain the scenario where I had to make use of this solution. Basically, I wanted to undo the background-color attribute set by another CSS. The expected end result was to make it look as though the original CSS had never applied the background-color attribute . Setting background-color:transparent; made that effective.

You can use position:absolute; to absolutely position an element within a parent div. When using position:absolute; the element will be positioned absolutely from the first positioned parent div, if it can't find one it will position absolutely from the window so you will need to make sure the content div is positioned.

To make the content div positioned, all position values that aren't static will work, but relative is the easiest since it doesn't change the divs positioning by itself.

So add position:relative; to the content div, remove the float from the button and add the following css to the button:

position: absolute;
right:    0;
bottom:   0;

typeof(MyType).GetField("fieldName", BindingFlags.NonPublic | BindingFlags.Instance)

You also can do it with functional programming:

from functools import reduce
reduce(lambda df1, df2: df1.merge(df2, "outer"), mydfs)

Use the TABLOCKX lock hint for your transaction. See this article for more information on locking.

A @ViewScoped bean lives exactly as long as a JSF view. It usually starts with a fresh new GET request, or with a navigation action, and will then live as long as the enduser submits any POST form in the view to an action method which returns null or void (and thus navigates back to the same view). Once you refresh the page, or return a non-null string (even an empty string!) navigation outcome, then the view scope will end.

A @RequestScoped bean lives exactly as long a HTTP request. It will thus be garbaged by end of every request and recreated on every new request, hereby losing all changed properties.

A @ViewScoped bean is thus particularly more useful in rich Ajax-enabled views which needs to remember the (changed) view state across Ajax requests. A @RequestScoped one would be recreated on every Ajax request and thus fail to remember all changed view state. Note that a @ViewScoped bean does not share any data among different browser tabs/windows in the same session like as a @SessionScoped bean. Every view has its own unique @ViewScoped bean.

You need %in% instead of ==:

library(dplyr)
target <- c("Tom", "Lynn")
filter(dat, name %in% target)  # equivalently, dat %>% filter(name %in% target)

Produces

  days name
1   88 Lynn
2   11  Tom
3    1  Tom
4  222 Lynn
5    2 Lynn

To understand why, consider what happens here:

dat$name == target
# [1] FALSE FALSE FALSE FALSE FALSE FALSE FALSE  TRUE

Basically, we're recycling the two length target vector four times to match the length of dat$name. In other words, we are doing:

 Lynn == Tom
  Tom == Lynn
Chris == Tom
 Lisa == Lynn
 ... continue repeating Tom and Lynn until end of data frame

In this case we don't get an error because I suspect your data frame actually has a different number of rows that don't allow recycling, but the sample you provide does (8 rows). If the sample had had an odd number of rows I would have gotten the same error as you. But even when recycling works, this is clearly not what you want. Basically, the statement dat$name == target is equivalent to saying:

return TRUE for every odd value that is equal to "Tom" or every even value that is equal to "Lynn".

It so happens that the last value in your sample data frame is even and equal to "Lynn", hence the one TRUE above.

To contrast, dat$name %in% target says:

for each value in dat$name, check that it exists in target.

Very different. Here is the result:

[1]  TRUE  TRUE FALSE FALSE FALSE  TRUE  TRUE  TRUE

Note your problem has nothing to do with dplyr, just the mis-use of ==.

Try:

$result = curl_exec($cURL);
$result = json_decode($result,true);

Now you can access MessageID from $result['MessageID'].

As for the database, it's simply using a query like so:

INSERT INTO `tableName`(`Cancelled`,`Queued`,`SMSError`,`SMSIncommingMessage`,`Sent`,`SentDateTime`) VALUES('?','?','?','?','?');

Prepared.

From Ask Tom

You should consider a schema to be the user account and collection of all objects therein as a schema for all intents and purposes.

SCOTT is a schema that includes the EMP, DEPT and BONUS tables with various grants, and other stuff.

SYS is a schema that includes tons of tables, views, grants, etc etc etc.

SYSTEM is a schema.....

Technically -- A schema is the set of metadata (data dictionary) used by the database, typically generated using DDL. A schema defines attributes of the database, such as tables, columns, and properties. A database schema is a description of the data in a database.

stata.replace<-function(data,replacevar,replacevalue,ifs) {
  ifs=parse(text=ifs)
  yy=as.numeric(eval(ifs,data,parent.frame()))
  x=sum(yy)
  data=cbind(data,yy)
  data[yy==1,replacevar]=replacevalue
  message=noquote(paste0(x, " replacement are made"))
  print(message)
  return(data[,1:(ncol(data)-1)])
}

Call this function using below line.

d=stata.replace(d,"under20",1,"age<20")

I wasn't satisfied with what was offered, so here's my proposal, using jQuery :

            <div id="playlist">
                <audio id="player" controls preload="metadata" volume="1">
                  <source src="" type="audio/mpeg">
                  Sorry, this browser doesn't support HTML 5.0
                </audio>
                <ul></ul>
            </div>

            <script>
                var folder = "audio";
                var playlist = [
                    "example1.mp3",
                    "example2.mp3"
                ];
                for (var i in playlist) {
                    jQuery('#playlist ul').append('<li>'+playlist[i]+'</li>');
                }

                var player = document.getElementById('player');
                var playing = playlist[0];
                player.src = folder + '/' + playing;

                function display(id) {
                    var list = jQuery('#playlist ul').children();
                    list.removeClass('playing');
                    jQuery(list[id]).addClass('playing');
                }

                display(0);

                player.onended = function(){
                    var ind_next = playlist.indexOf(playing) + 1;

                    if (ind_next !== 0) {
                        player.src = folder + '/' + playlist[ind_next];
                        playing = player.src;
                        display(ind_next)
                        player.play();
                    }
                }
            </script>

You only have to edit the playlist array, and you're done

With Homebrew and jenv:

Assumption: Mac machine and you already have installed homebrew.

Install cask:

$ brew tap caskroom/cask
$ brew tap caskroom/versions

To install latest java:

$ brew cask install java

To install java 8:

$ brew cask install java8

To install java 9:

$ brew cask install java9

If you want to install/manage multiple version then you can use 'jenv':

Install and configure jenv:

$ brew install jenv
$ echo 'export PATH="$HOME/.jenv/bin:$PATH"' >> ~/.bash_profile
$ echo 'eval "$(jenv init -)"' >> ~/.bash_profile
$ source ~/.bash_profile

Add the installed java to jenv:

$ jenv add /Library/Java/JavaVirtualMachines/jdk1.8.0_202.jdk/Contents/Home
$ jenv add /Library/Java/JavaVirtualMachines/jdk1.11.0_2.jdk/Contents/Home

To see all the installed java:

$ jenv versions

Above command will give the list of installed java:

* system (set by /Users/lyncean/.jenv/version)
1.8
1.8.0.202-ea
oracle64-1.8.0.202-ea

Configure the java version which you want to use:

$ jenv global oracle64-1.6.0.39

Haha, oh boy, I figured it out. Somehow, someway, I did not install the Database Engine when I installed SQL Server 2008. I have no idea how I missed that, but that's what happened.

Also, you don't have to instantiate the class to get its type for deserialization:

public static T Deserialise<T>(string json)
{
    using (var ms = new MemoryStream(Encoding.Unicode.GetBytes(json)))
    {
        var serialiser = new DataContractJsonSerializer(typeof(T));
        return (T)serialiser.ReadObject(ms);
    }
}

To Build/run C++ projects in VS code , you manually need to configure tasks.json file which is in .vscode folder in workspace folder . To open tasks.json , press ctrl + shift + P , and type Configure tasks , and press enter, it will take you to tasks.json

Here i am providing my tasks.json file with some comments to make the file more understandable , It can be used as a reference for configuring tasks.json , i hope it will be useful

tasks.json

{
    "version": "2.0.0",

    "tasks": [

        {
            "label": "build & run",     //It's name of the task , you can have several tasks 
            "type": "shell",    //type can be either 'shell' or 'process' , more details will be given below
            "command": "g++",   
            "args": [
                "-g",   //gnu debugging flag , only necessary if you want to perform debugging on file  
                "${file}",  //${file} gives full path of the file
                "-o",   
                "${workspaceFolder}\\build\\${fileBasenameNoExtension}",    //output file name
                "&&",   //to join building and running of the file
                "${workspaceFolder}\\build\\${fileBasenameNoExtension}"
            ],
            "group": {
                "kind": "build",    //defines to which group the task belongs
                "isDefault": true
            },
            "presentation": {   //Explained in detail below
                "echo": false,
                "reveal": "always",
                "focus": true,
                "panel": "shared",
                "clear": false,
                "showReuseMessage": false
            },
            "problemMatcher": "$gcc"
        },

    ]
}

Now , stating directly from the VS code tasks documentation

description of type property :

• type: The task's type. For a custom task, this can either be shell or process. If shell is specified, the command is interpreted as a shell command (for example: bash, cmd, or PowerShell). If process is specified, the command is interpreted as a process to execute.

The behavior of the terminal can be controlled using the presentation property in tasks.json . It offers the following properties:

• reveal: Controls whether the Integrated Terminal panel is brought to front. Valid values are:

  • always - The panel is always brought to front. This is the default
  • never - The user must explicitly bring the terminal panel to the front using the View > Terminal command (Ctrl+`).
  • silent - The terminal panel is brought to front only if the output is not scanned for errors and warnings.

• focus: Controls whether the terminal is taking input focus or not. Default is false.

• echo: Controls whether the executed command is echoed in the terminal. Default is true.
• showReuseMessage: Controls whether to show the "Terminal will be reused by tasks, press any key to close it" message.
• panel: Controls whether the terminal instance is shared between task runs. Possible values are:
  • shared: The terminal is shared and the output of other task runs are added to the same terminal.
  • dedicated: The terminal is dedicated to a specific task. If that task is executed again, the terminal is reused. However, the output of a different task is presented in a different terminal.
  • new: Every execution of that task is using a new clean terminal.
• clear: Controls whether the terminal is cleared before this task is run. Default is false.

If you need the same functionality using the DB, in Laravel >= 5.5 you can use:

DB::table('table_name')->updateOrInsert($attributes, $values);

or the shorthand version when $attributes and $values are the same:

DB::table('table_name')->updateOrInsert($values);

This is what SSMS uses when you script using the DROP and CREATE option

IF EXISTS (SELECT *
           FROM   sys.objects
           WHERE  object_id = OBJECT_ID(N'[dbo].[foo]')
                  AND type IN ( N'FN', N'IF', N'TF', N'FS', N'FT' ))
  DROP FUNCTION [dbo].[foo]

GO 

This approach to deploying changes means that you need to recreate all permissions on the object so you might consider ALTER-ing if Exists instead.

If you just want to use switch/case, you can do something like this, pseudo-code:

    string message = "test of mine";
    string[] keys = new string[] {"test2",  "test"  };

    string sKeyResult = keys.FirstOrDefault<string>(s=>message.Contains(s));

    switch (sKeyResult)
    {
        case "test":
            Console.WriteLine("yes for test");
            break;
        case "test2":
            Console.WriteLine("yes for test2");
            break;
    }

But if the quantity of keys is a big, you can just replace it with dictionary, like this:

static Dictionary<string, string> dict = new Dictionary<string, string>();
static void Main(string[] args)
{
    string message = "test of mine";      

    // this happens only once, during initialization, this is just sample code
    dict.Add("test", "yes");
    dict.Add("test2", "yes2"); 


    string sKeyResult = dict.Keys.FirstOrDefault<string>(s=>message.Contains(s));

    Console.WriteLine(dict[sKeyResult]); //or `TryGetValue`... 
 }

You need

var i = $("#panel input"); 

or, depending on what exactly you want (see below)

var i = $("#panel :input"); 

the > will restrict to children, you want all descendants.

EDIT: As Nick pointed out, there's a subtle difference between $("#panel input") and $("#panel :input).

The first one will only retrieve elements of type input, that is <input type="...">, but not <textarea>, <button> and <select> elements. Thanks Nick, didn't know this myself and corrected my post accordingly. Left both options, because I guess the OP wasn't aware of that either and -technically- asked for inputs... :-)

TL;DR: dependency conflicts: Updating one requires (by it's requirements) to downgrade another

You are right:

conda update --all

is actually the way to go¹. Conda always tries to upgrade the packages to the newest version in the series (say Python 2.x or 3.x).

Dependency conflicts

But it is possible that there are dependency conflicts (which prevent a further upgrade). Conda usually warns very explicitly if they occur.

e.g. X requires Y <5.0, so Y will never be >= 5.0

That's why you 'cannot' upgrade them all.

Resolving

To add: maybe it could work but a newer version of X working with Y > 5.0 is not available in conda. It is possible to install with pip, since more packages are available in pip. But be aware that pip also installs packages if dependency conflicts exist and that it usually breaks your conda environment in the sense that you cannot reliably install with conda anymore. If you do that, do it as a last resort and after all packages have been installed with conda. It's rather a hack.

A safe way you can try is to add conda-forge as a channel when upgrading (add -c conda-forge as a flag) or any other channel you find that contains your package if you really need this new version. This way conda does also search in this places for available packages.

Considering your update: You can upgrade them each separately, but doing so will not only include an upgrade but also a downgrade of another package as well. Say, to add to the example above:

X > 2.0 requires Y < 5.0, X < 2.0 requires Y > 5.0

So upgrading Y > 5.0 implies downgrading X to < 2.0 and vice versa.

(this is a pedagogical example, of course, but it's the same in reality, usually just with more complicated dependencies and sub-dependencies)

So you still cannot upgrade them all by doing the upgrades separately; the dependencies are just not satisfiable so earlier or later, an upgrade will downgrade an already upgraded package again. Or break the compatibility of the packages (which you usually don't want!), which is only possible by explicitly invoking an ignore-dependencies and force-command. But that is only to hack your way around issues, definitely not the normal-user case!

¹ If you actually want to update the packages of your installation, which you usually don't. The command run in the base environment will update the packages in this, but usually you should work with virtual environments (conda create -n myenv and then conda activate myenv). Executing conda update --all inside such an environment will update the packages inside this environment. However, since the base environment is also an environment, the answer applies to both cases in the same way.

In my case, the customer forgot to add new IP address in their SMTP settings. Open IIS 6.0 in the server which sets up the smtp, right click Smtp virtual server, choose Properties, Access tab, click Connections, add IP address of the new server. Then click Relay, also add IP address of the new server. This solved my issue.

SQL*Plus uses &1, &2... &n to access the parameters.

Suppose you have the following script test.sql:

SET SERVEROUTPUT ON
SPOOL test.log
EXEC dbms_output.put_line('&1 &2');
SPOOL off

you could call this script like this for example:

$ sqlplus login/pw @test Hello World!

Edit:

In a UNIX script you would usually call a SQL script like this:

sqlplus /nolog << EOF
connect user/password@db
@test.sql Hello World!
exit
EOF

so that your login/password won't be visible with another session's ps

The other answers will break if output of command contains spaces (which is rather frequent) or glob characters like *, ?, [...].

To get the output of a command in an array, with one line per element, there are essentially 3 ways:

1. With Bash=4 use mapfile—it's the most efficient:

   mapfile -t my_array < <( my_command )
   

2. Otherwise, a loop reading the output (slower, but safe):

   my_array=()
   while IFS= read -r line; do
       my_array+=( "$line" )
   done < <( my_command )
   

3. As suggested by Charles Duffy in the comments (thanks!), the following might perform better than the loop method in number 2:

   IFS=$'\n' read -r -d '' -a my_array < <( my_command && printf '\0' )
   

   Please make sure you use exactly this form, i.e., make sure you have the following:

   • IFS=$'\n' on the same line as the read statement: this will only set the environment variable IFS for the read statement only. So it won't affect the rest of your script at all. The purpose of this variable is to tell read to break the stream at the EOL character \n.
   • -r: this is important. It tells read to not interpret the backslashes as escape sequences.
   • -d '': please note the space between the -d option and its argument ''. If you don't leave a space here, the '' will never be seen, as it will disappear in the quote removal step when Bash parses the statement. This tells read to stop reading at the nil byte. Some people write it as -d $'\0', but it is not really necessary. -d '' is better.
   • -a my_array tells read to populate the array my_array while reading the stream.
   • You must use the printf '\0' statement after my_command, so that read returns 0; it's actually not a big deal if you don't (you'll just get an return code 1, which is okay if you don't use set -e – which you shouldn't anyway), but just bear that in mind. It's cleaner and more semantically correct. Note that this is different from printf '', which doesn't output anything. printf '\0' prints a null byte, needed by read to happily stop reading there (remember the -d '' option?).

If you can, i.e., if you're sure your code will run on Bash=4, use the first method. And you can see it's shorter too.

If you want to use read, the loop (method 2) might have an advantage over method 3 if you want to do some processing as the lines are read: you have direct access to it (via the $line variable in the example I gave), and you also have access to the lines already read (via the array ${my_array[@]} in the example I gave).

Note that mapfile provides a way to have a callback eval'd on each line read, and in fact you can even tell it to only call this callback every N lines read; have a look at help mapfile and the options -C and -c therein. (My opinion about this is that it's a little bit clunky, but can be used sometimes if you only have simple things to do — I don't really understand why this was even implemented in the first place!).

Now I'm going to tell you why the following method:

my_array=( $( my_command) )

is broken when there are spaces:

$ # I'm using this command to test:
$ echo "one two"; echo "three four"
one two
three four
$ # Now I'm going to use the broken method:
$ my_array=( $( echo "one two"; echo "three four" ) )
$ declare -p my_array
declare -a my_array='([0]="one" [1]="two" [2]="three" [3]="four")'
$ # As you can see, the fields are not the lines
$
$ # Now look at the correct method:
$ mapfile -t my_array < <(echo "one two"; echo "three four")
$ declare -p my_array
declare -a my_array='([0]="one two" [1]="three four")'
$ # Good!

Then some people will then recommend using IFS=$'\n' to fix it:

$ IFS=$'\n'
$ my_array=( $(echo "one two"; echo "three four") )
$ declare -p my_array
declare -a my_array='([0]="one two" [1]="three four")'
$ # It works!

But now let's use another command, with globs:

$ echo "* one two"; echo "[three four]"
* one two
[three four]
$ IFS=$'\n'
$ my_array=( $(echo "* one two"; echo "[three four]") )
$ declare -p my_array
declare -a my_array='([0]="* one two" [1]="t")'
$ # What?

That's because I have a file called t in the current directory… and this filename is matched by the glob [three four]… at this point some people would recommend using set -f to disable globbing: but look at it: you have to change IFS and use set -f to be able to fix a broken technique (and you're not even fixing it really)! when doing that we're really fighting against the shell, not working with the shell.

$ mapfile -t my_array < <( echo "* one two"; echo "[three four]")
$ declare -p my_array
declare -a my_array='([0]="* one two" [1]="[three four]")'

here we're working with the shell!

You can use COPY table TO ... WITH BINARY which is "somewhat faster than the text and CSV formats." Only do this if you have millions of rows to insert, and if you are comfortable with binary data.

Here is an example recipe in Python, using psycopg2 with binary input.

$url='Your url'; // Specify your url
$data= array('parameterkey1'=>value,'parameterkey2'=>value); // Add parameters in key value
$ch = curl_init(); // Initialize cURL
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_exec($ch);
curl_close($ch);

You are inside a namespace so you should use \Exception to specify the global namespace:

try {

  $this->buildXMLHeader();

} catch (\Exception $e) {

    return $e->getMessage();
}

In your code you've used catch (Exception $e) so Exception is being searched in/as:

App\Services\PayUService\Exception

Since there is no Exception class inside App\Services\PayUService so it's not being triggered. Alternatively, you can use a use statement at the top of your class like use Exception; and then you can use catch (Exception $e).

DLL files contain an Export Table which is a list of symbols which can be looked up by the calling program. The symbols are typically functions with the C calling convention (__stcall). The export table also contains the address of the function.

With this information, the calling program can then call the functions within the DLL even though it did not have access to the DLL at compile time.

Introducing Dynamic Link Libraries has some more information.

oops! just found myself: just add this line on any element you need

   -webkit-appearance: none;

Try to add export PATH=$PATH:/home/me/play in ~/.bashrc file.

This is may be late but for those who are still looking for answer for this I found a project on git hub and this is the only one that actually fit my needs. android-materialshadowninepatch

Try this little crumpet:

-(void)saveUserSettings{
NSNumber*   value;

value = [NSNumber numberWithFloat:self.sensativity];
[[NSUserDefaults standardUserDefaults] setObject:value forKey:@"sensativity"];
}
-(void)loadUserSettings{
    NSNumber*   value;
    value = [[NSUserDefaults standardUserDefaults] objectForKey:@"sensativity"];
    if(value == nil){
        self.sensativity = 4.0;
    }else{
        self.sensativity = [value floatValue];
    }
}

Treat everything as an object. Seems to work for me.

What the provided links to comparisons/animations do not consider is when the amount of data exceed available memory --- at which point the number of passes over the data, i.e. I/O-costs, dominate the runtime. If you need to do that, read up on "external sorting" which usually cover variants of merge- and heap sorts.

http://corte.si/posts/code/visualisingsorting/index.html and http://corte.si/posts/code/timsort/index.html also have some cool images comparing various sorting algorithms.

There are two way that you can add two number in jQuery

First way:

var x = parseInt(a) + parseInt(b);
alert(x);

Second Way:

var x = parseInt(a+2);
alert(x);

Now come your question

var a = parseInt($("#a").val()); 
var b = parseInt($("#b").val());
alert(a+b);

Simplest and fastest solution.

$sSubDomain = str_replace('.example.com','',$_SERVER['HTTP_HOST']);

You can convert (ie. force) the column data to text... Try this (Note: These instructions are based on Excel 2007)...

The following steps should force Excel to treat the column as text:

Open your spreadsheet with Excel.

Select the whole column that contains your "mostly numeric data" by clicking on the column header.

Click on the Data tab on the ribbon menu.

Select Text to Columns. This will bring up the Convert Text to Columns Wizard.

-On Step 1: Click Next

-On Step 2: Click Next

-On Step 3: Select Text and click Finish

Save your Excel sheet.

Retry the import using the SQL Server 2005 Import Data Wizard.

Also, here's a link to another question which has additional responses:

These days you can use a Media Queries Level 4 feature to check if the device has the ability to 'hover' over elements.

@media (hover: hover) { ... }

Since the ipad has no 'hover' state you can effectively target touch devices like the ipad.

I think you can do this which get your local file path

if not os.path.isdir(f_dir):
    os.mkdirs(f_dir)

try:
    approot = os.path.dirname(os.path.abspath(__file__))
except NameError:
    approot = os.path.dirname(os.path.abspath(sys.argv[1]))
    my_dir= os.path.join(approot, 'f_dir')

Solved myself. Done some small structural changes also. Route from Component1 to Component2 is done by a single <router-outlet>. Component2 to Comonent3 and Component4 is done by multiple <router-outlet name= "xxxxx"> The resulting contents are :

Component1.html

<nav>
    <a routerLink="/two" class="dash-item">Go to 2</a>
</nav>
    <router-outlet></router-outlet>

Component2.html

 <a [routerLink]="['/two', {outlets: {'nameThree': ['three']}}]">In Two...Go to 3 ...       </a>
 <a [routerLink]="['/two', {outlets: {'nameFour': ['four']}}]">   In Two...Go to 4 ...</a>

 <router-outlet name="nameThree"></router-outlet>
 <router-outlet name="nameFour"></router-outlet>

The '/two' represents the parent component and ['three']and ['four'] represents the link to the respective children of component2 . Component3.html and Component4.html are the same as in the question.

router.module.ts

const routes: Routes = [
{
    path: '',
    redirectTo: 'one',
    pathMatch: 'full'
},
{
    path: 'two',
    component: ClassTwo, children: [

        {
            path: 'three',
            component: ClassThree,
            outlet: 'nameThree'
        },
        {
            path: 'four',
            component: ClassFour,
            outlet: 'nameFour'
        }
    ]
},];

A single line method within bash works like this.

[some out put] >$(date "+%Y.%m.%d-%H.%M.%S").ver

will create a file with a timestamp name with ver extension. A working file listing snap shot to a date stamp file name as follows can show it working.

find . -type f -exec ls -la {} \; | cut -d ' ' -f 6- >$(date "+%Y.%m.%d-%H.%M.%S").ver

Of course

cat somefile.log > $(date "+%Y.%m.%d-%H.%M.%S").ver

or even simpler

ls > $(date "+%Y.%m.%d-%H.%M.%S").ver

Try using the css properties min and max as a workaround

For example:

width: min(50vw, 200px);

means the width will be the smallest of the two values.

width: max(50vw, 200px);

means the width will be the larger of the two values.

The answer above with spark-csv is correct but there is an issue - the library creates several files based on the data frame partitioning. And this is not what we usually need. So, you can combine all partitions to one:

df.coalesce(1).
    write.
    format("com.databricks.spark.csv").
    option("header", "true").
    save("myfile.csv")

and rename the output of the lib (name "part-00000") to a desire filename.

The more general answer is

UPDATE mysql.user SET host = {newhost} WHERE user = {youruser}

I had set:

log4j.appender.R=org.apache.log4j.DailyRollingFileAppender
log4j.appender.R.DatePattern='.'yyyy-MM-dd
# Archive log files (Keep one year of daily files)
log4j.appender.R.MaxBackupIndex=367

Like others before me, the DEBUG option showed me the error:

log4j:WARN No such property [maxBackupIndex] in org.apache.log4j.DailyRollingFileAppender.

Here is an idea I have not tried yet, suppose I set the DatePattern such that the files overwrite each other after the required time period. To retain a year's worth I could try setting:

log4j.appender.R.DatePattern='.'MM-dd

Would it work or would it cause an error ? Like that it will take a year to find out, I could try:

log4j.appender.R.DatePattern='.'dd

but it will still take a month to find out.

This query will get you all the tables in the database

The "unchecked or unsafe operations" warning was added when java added Generics, if I remember correctly. It's usually asking you to be more explicit about types, in one way or another.

For example. the code ArrayList foo = new ArrayList(); triggers that warning because javac is looking for ArrayList<String> foo = new ArrayList<String>();

Graphically, the cron syntax for Quarz is (source):

+-------------------- second (0 - 59)
|  +----------------- minute (0 - 59)
|  |  +-------------- hour (0 - 23)
|  |  |  +----------- day of month (1 - 31)
|  |  |  |  +-------- month (1 - 12)
|  |  |  |  |  +----- day of week (0 - 6) (Sunday=0 or 7)
|  |  |  |  |  |  +-- year [optional]
|  |  |  |  |  |  |
*  *  *  *  *  *  * command to be executed 

So if you want to run a command every 30 minutes you can say either of these:

0 0/30 * * * * ?
0 0,30 * * * * ?

You can check crontab expressions using either of these:

• crontab.guru — (disclaimer: I am not related to that page at all, only that I find it very useful). This page uses UNIX style of cron that does not have seconds in it, while Spring does as the first field.
• Cron Expression Generator & Explainer - Quartz — cron formatter, allowing seconds also.

There are two main types of margin collapse:

• Collapsing margins between adjacent elements
• Collapsing margins between parent and child elements

Using a padding or border will prevent collapse only in the latter case. Also, any value of overflow different from its default (visible) applied to the parent will prevent collapse. Thus, both overflow: auto and overflow: hidden will have the same effect. Perhaps the only difference when using hidden is the unintended consequence of hiding content if the parent has a fixed height.

Other properties that, once applied to the parent, can help fix this behaviour are:

• float: left / right
• position: absolute
• display: inline-block / flex

You can test all of them here: http://jsfiddle.net/XB9wX/1/.

I should add that, as usual, Internet Explorer is the exception. More specifically, in IE 7 margins do not collapse when some kind of layout is specified for the parent element, such as width.

The problem with storing only filepaths to images in a database is that the database's integrity can no longer be forced.

If the actual image pointed to by the filepath becomes unavailable, the database unwittingly has an integrity error.

Given that the images are the actual data being sought after, and that they can be managed easier (the images won't suddenly disappear) in one integrated database rather than having to interface with some kind of filesystem (if the filesystem is independently accessed, the images MIGHT suddenly "disappear"), I'd go for storing them directly as a BLOB or such.

Try specifying a DC in DomainB using the -Server property. Ex:

Get-ADUser -Server "dc01.DomainB.local" -Filter {EmailAddress -like "*Smith_Karla*"} -Properties EmailAddress

As others have said you are "tainting" the canvas by loading from a cross origins domain.

https://developer.mozilla.org/en-US/docs/HTML/CORS_Enabled_Image

However, you may be able to prevent this by simply setting:

img.crossOrigin = "Anonymous";

This only works if the remote server sets the following header appropriately:

Access-Control-Allow-Origin "*"

The Dropbox file chooser when using the "direct link" option is a great example of this. I use it on oddprints.com to hoover up images from the remote dropbox image url, into my canvas, and then submit the image data back into my server. All in javascript

I just cleaned up RHT's answer to eliminate some warnings and thought I would share. Eclipse did most of the work:

public List<HashMap<String,Object>> convertResultSetToList(ResultSet rs) throws SQLException {
    ResultSetMetaData md = rs.getMetaData();
    int columns = md.getColumnCount();
    List<HashMap<String,Object>> list = new ArrayList<HashMap<String,Object>>();

    while (rs.next()) {
        HashMap<String,Object> row = new HashMap<String, Object>(columns);
        for(int i=1; i<=columns; ++i) {
            row.put(md.getColumnName(i),rs.getObject(i));
        }
        list.add(row);
    }

    return list;
}

I know this is not the OP's problem, but I ran into the same error with an entirely different basis, so I just wanted to drop it here in case anyone else has the same. This is Windows-specific, and I assume does not affect Linux users.

I had a LibreOffice doc file, call it final report.odt. I later changed its case to Final Report.odt. In Windows, this doesn't even count as a rename. final report.odt, Final Report.odt, FiNaL RePoRt.oDt are all the same. In Linux, these are all distinct.

When I eventually went to git rm "Final Report.odt" and got the "pathspec did not match any files" error. Only when I use the original casing at the time the file was added -- git rm "final report.odt" -- did it work.

Lesson learned: to change the case I should have instead done:

git mv "final report.odt" temp.odt
git mv temp.odt "Final Report.odt"

Again, that wasn't the problem for the OP here; and wouldn't affect a Linux user, as his posts shows he clearly is. I'm just including it for others who may have this problem in Windows git and stumble onto this question.

SELECT tab.*,
    row_number() OVER () as rnum
  FROM tab;

Here's the relevant section in the docs.

P.S. This, in fact, fully matches the answer in the referenced question.

I couldn't get Facebook to pick the right image from a specific post, so I did what's outlined on this page:

https://webapps.stackexchange.com/questions/18468/adding-meta-tags-to-individual-blogger-posts

In other words, something like this:

<b:if cond='data:blog.url == "http://urlofyourpost.com"'>
  <meta content='http://urlofyourimage.png' property='og:image'/>
 </b:if>

Basically, you're going to hard code an if statement into your site's HTML to get it to change the meta content for whatever you've changed for that one post. It's a messy solution, but it works.

Informally

entropy is availability of information or knowledge, Lack of information will leads to difficulties in prediction of future which is high entropy (next word prediction in text mining) and availability of information/knowledge will help us more realistic prediction of future (low entropy).

Relevant information of any type will reduce entropy and helps us predict more realistic future, that information can be word "meat" is present in sentence or word "meat" is not present. This is called Information Gain

Formally

entropy is lack of order of predicability

In Ubuntu:

For me, IntelliJ Event Log (right bottom corner) had below logs:

Error running EntitmentTooling-Debug: Cannot run program "/path-to/apache-tomcat-8.5.15/bin/catalina.sh" (in directory "path-to/apache-tomcat-8.5.15/bin"): error=13, Permission denied

Error running EntitmentTooling-Debug: Unable to open debugger port (127.0.0.1:58804): java.net.SocketException "Socket closed"

The command

$ chmod a+x /path-to/apache-tomcat-8.5.15/bin/catalina.sh

to sufficiently change privileges worked for me.

XmlDocument doc = new XmlDocument();
doc.LoadXml(str);

Where str is your XML string. See the MSDN article for more info.

for (int i = 0; i < list.size(); i++) {
  for (int j = i+1; j < list.size(); j++) {
    // compare list.get(i) and list.get(j)

}

Code for Find the Column Name same as using the Like in sql.

foreach (DataGridViewColumn column in GrdMarkBook.Columns)  
                      //GrdMarkBook is Data Grid name
{                      
    string HeaderName = column.HeaderText.ToString();

    //  This line Used for find any Column Have Name With Exam

    if (column.HeaderText.ToString().ToUpper().Contains("EXAM"))
    {
        int CoumnNo = column.Index;
    }
}

You can use jQuery's $.map.

var foo = { 'alpha' : 'puffin', 'beta' : 'beagle' },
keys = $.map(foo, function(v, i){
  return i;
});

You must declare the prototype it before using it:

class User;

class MyMessageBox
{
public:
 void sendMessage(Message *msg, User *recvr);
 Message receiveMessage();
 vector<Message> *dataMessageList;
};

class User
{
public:
 MyMessageBox dataMsgBox;
};

edit: Swapped the types

Just use something like:

var author = $('meta[name=author]').attr('content');

I changed (in Annotation model class)

fetch = FetchType.LAZY

to

fetch = FetchType.EAGER

and worked in pretty way...

Love it.

When uploading .mp4 file into Perl script, using CGI.pm I see it as video/mp when printing out Content-type for the uploaded file. I hope it will help someone.

None of these solutions worked for me.

Instead, I elaborate on @Martin v. Löwis 's mention of setting a config file for SSH.

SSH will look for the user's ~/.ssh/config file. I have mine setup as:

Host gitserv
    Hostname remote.server.com
    IdentityFile ~/.ssh/id_rsa.github
    IdentitiesOnly yes # see NOTES below

And I add a remote git repository:

git remote add origin git@gitserv:myrepo.git

And then git commands work normally for me.

git push -v origin master

NOTES

• The IdentitiesOnly yes is required to prevent the SSH default behavior of sending the identity file matching the default filename for each protocol. If you have a file named ~/.ssh/id_rsa that will get tried BEFORE your ~/.ssh/id_rsa.github without this option.

The "setStartOffset" should be smaller, else animation starts at view alpha 0.xf and waits for start offset before animating to 1f. Hope the following code helps.

AlphaAnimation animation1 = new AlphaAnimation(0.1f, 1f);

animation1.setDuration(1000);
animation1.setStartOffset(50);

animation1.setFillAfter(true);

view.setVisibility(View.VISIBLE);

view.startAnimation(animation1);

I have created an action in the Accounts controller that calls a function to create the roles and assign the Admin role to the default user. (You should probably remove the default user in production):

    private async Task CreateRolesandUsers()
    {  
        bool x = await _roleManager.RoleExistsAsync("Admin");
        if (!x)
        {
            // first we create Admin rool    
            var role = new IdentityRole();
            role.Name = "Admin";
            await _roleManager.CreateAsync(role);

            //Here we create a Admin super user who will maintain the website                   

            var user = new ApplicationUser();
            user.UserName = "default";
            user.Email = "[email protected]";

            string userPWD = "somepassword";

            IdentityResult chkUser = await _userManager.CreateAsync(user, userPWD);

            //Add default User to Role Admin    
            if (chkUser.Succeeded)
            {
                var result1 = await _userManager.AddToRoleAsync(user, "Admin");
            }
        }

        // creating Creating Manager role     
        x = await _roleManager.RoleExistsAsync("Manager");
        if (!x)
        {
            var role = new IdentityRole();
            role.Name = "Manager";
            await _roleManager.CreateAsync(role);
        }

        // creating Creating Employee role     
        x = await _roleManager.RoleExistsAsync("Employee");
        if (!x)
        {
            var role = new IdentityRole();
            role.Name = "Employee";
            await _roleManager.CreateAsync(role);
        }
  }

After you could create a controller to manage roles for the users.

We've used a solution based on timeGetTime in winmm.dll for millisecond accuracy for many years. See http://www.aboutvb.de/kom/artikel/komstopwatch.htm

The article is in German, but the code in the download (a VBA class wrapping the dll function call) is simple enough to use and understand without being able to read the article.

Single line code.. will return true or false

!!(arr.indexOf("val")+1)

If you want to convert an Array of digits to a single number just use:

Number(arrayOfDigits.join(''));

Example

const arrayOfDigits = [1,2,3,4,5];

const singleNumber = Number(arrayOfDigits.join(''));

console.log(singleNumber); //12345

For those who are still trying, this link helped me out, too; it just puts it all together:

http://dotnetslackers.com/VB_NET/re-36138_How_To_Get_Selected_Date_from_MonthCalendar_control.aspx

private void MonthCalendar1_DateChanged(object sender, System.Windows.Forms.DateRangeEventArgs e)
{
//Display the dates for selected range
Label1.Text = "Dates Selected from :" + (MonthCalendar1.SelectionRange.Start() + " to " + MonthCalendar1.SelectionRange.End);

//To display single selected of date
//MonthCalendar1.MaxSelectionCount = 1;

//To display single selected of date use MonthCalendar1.SelectionRange.Start/ MonthCalendarSelectionRange.End
Label2.Text = "Date Selected :" + MonthCalendar1.SelectionRange.Start;
}

I have updated your jsfiddle and here is CSS changes you need to do:

#content
{
    min-width:700px;
    margin-right: -210px;
    width:100%;
    float:left;
    background-color:AppWorkspace;
}

I use Jquery for this

function setSizes() {
   var containerHeight = $("#listContainer").height();
   $("#myList").height(containerHeight - 18);
}

then I bind the window resize to recalc it whenever the browser window is resized (if container's size changed with window resize)

$(window).resize(function() { setSizes(); });

The short answer: the setting needs to be setup when the connection to the MySQL server is established. For example, if using MYSQLi / PHP, it will look something like this:

$ myConn = mysqli_init(); 
$ myConn->options(MYSQLI_INIT_COMMAND, 'SET SESSION group_concat_max_len = 1000000');

Therefore, if you are using a home-brewed framework, well, you need to look for the place in the code when the connection is establish and provide a sensible value.

I am still using Codeigniter 3 on 2020, so in this framework, the code to add is in the application/system/database/drivers/mysqli/mysqli_driver.php, the function is named db_connect();

public function db_connect($persistent = FALSE)
    {
        // Do we have a socket path?
        if ($this->hostname[0] === '/')
        {
            $hostname = NULL;
            $port = NULL;
            $socket = $this->hostname;
        }
        else
        {
            $hostname = ($persistent === TRUE)
                ? 'p:'.$this->hostname : $this->hostname;
            $port = empty($this->port) ? NULL : $this->port;
            $socket = NULL;
        }

        $client_flags = ($this->compress === TRUE) ? MYSQLI_CLIENT_COMPRESS : 0;
        $this->_mysqli = mysqli_init();

        $this->_mysqli->options(MYSQLI_OPT_CONNECT_TIMEOUT, 10);
        $this->_mysqli->options(MYSQLI_INIT_COMMAND, 'SET SESSION group_concat_max_len = 1000000');

...
    }

Go to the Sql tab run one of the below query:

delete from tableName;

Delete: will delete all rows from your table. Next insert will take next auto increment id.

or

truncate tableName;

Truncate: will also delete the rows from your table but it will start from new row with 1.

A detailed blog with example: http://sforsuresh.in/phpmyadmin-deleting-rows-mysql-table/

All work perfectly :)

 NSString *test = @"test";
 unichar a;
 int index = 5;
    
 @try {
    a = [test characterAtIndex:index];
 }
 @catch (NSException *exception) {
    NSLog(@"%@", exception.reason);
    NSLog(@"Char at index %d cannot be found", index);
    NSLog(@"Max index is: %lu", [test length] - 1);
 }
 @finally {
    NSLog(@"Finally condition");
 }

Log:

[__NSCFConstantString characterAtIndex:]: Range or index out of bounds

Char at index 5 cannot be found

Max index is: 3

Finally condition

Try changing your CSS to this

button #rock {
    background: url('img/rock.png') no-repeat;
}

...provided that the image is in that place

I think this is the simplest way:

<select onchange="if (this.value) window.location.href=this.value">
    <option value="">Pick one:</option>
    <option value="/foo">Foo</option>
    <option value="/bar">Bar</option>
</select>

You don't have to add file.py.

Just keep the file in the same location with the file from where you want to import it. Then just import your functions:

from file import a, b

Most of the answers here have dealt with how to mange EOFError exceptions, which is really handy if you're unsure about whether the pickled object is empty or not.

However, if you're surprised that the pickle file is empty, it could be because you opened the filename through 'wb' or some other mode that could have over-written the file.

for example:

filename = 'cd.pkl'
with open(filename, 'wb') as f:
    classification_dict = pickle.load(f)

This will over-write the pickled file. You might have done this by mistake before using:

...
open(filename, 'rb') as f:

And then got the EOFError because the previous block of code over-wrote the cd.pkl file.

When working in Jupyter, or in the console (Spyder) I usually write a wrapper over the reading/writing code, and call the wrapper subsequently. This avoids common read-write mistakes, and saves a bit of time if you're going to be reading the same file multiple times through your travails

Possibly this can be of great help for you.

This worked for me:

cd [..LARAVEL PROJECT ROOT]
sudo find . -type f -exec chmod 644 {} \;
sudo find . -type d -exec chmod 755 {} \;
sudo chmod -R 777 ./storage
sudo chmod -R 777 ./bootstrap/cache/

Only if you use npm (VUE, compiling SASS, etc..) add this:

sudo chmod -R 777 ./node_modules/

What it does:

• Change all file permissions to 644
• Change all folder permissions to 755
• For storage and bootstrap cache (special folders used by laravel for creating and executing files, not available from outside) set permission to 777, for anything inside
• For nodeJS executable, same as above

Note: Maybe you can not, or don't need, to do it with sudo prefix. it depends on your user's permissions, group, etc...

Here is a way that addresses a few issues:

1. Alignment issues after content is updated, especially if the placement is "top". The key is calling ._popper.update(), which recalculates the position of the popover.
2. Width change after the content is updated. It doesn't break anything, it just looks jarring to the user. To lessen that, I set the width of the popover to 100% (which is then capped by the max-width).

var e = $("#whatever");
e.popover({
    placement: "top",
    trigger: "hover",
    title: "Test Popover",
    content: "<span class='content'>Loading...</span>",
    html: true
}).on("inserted.bs.popover", function() {
    var popover = e.data('bs.popover');
    var tip = $(popover.tip);
    tip.css("width", "100%");
    $.ajax("/whatever")
        .done(function(data) {
            tip.find(".content").text(data);
            popover._popper.update();
        }).fail(function() {
            tip.find(".content").text("Sorry, something went wrong");
        });
});

In your CSS file:

input { margin-bottom: 10px; }
