I needed to run a Spring .jar application as a service, and found a simple way to run this as a specific user:

I changed the owner and group of my jar file to the user I wanted to run as. Then symlinked this jar in init.d and started the service.

So:

#chown myuser:myuser /var/lib/jenkins/workspace/springApp/target/springApp-1.0.jar

#ln -s /var/lib/jenkins/workspace/springApp/target/springApp-1.0.jar /etc/init.d/springApp

#service springApp start

#ps aux | grep java
myuser    9970  5.0  9.9 4071348 386132 ?      Sl   09:38   0:21 /bin/java -Dsun.misc.URLClassPath.disableJarChecking=true -jar /var/lib/jenkins/workspace/springApp/target/springApp-1.0.jar

Your x and y values ??are not running so first of all youre begin to write this point

 import numpy as np
 import pandas as pd
 import matplotlib as plt

 dataframe=pd.read_csv(".\datasets\Position_Salaries.csv")

 x=dataframe.iloc[:,1:2].values 
 y=dataframe.iloc[:,2].values    
 x1=dataframe.iloc[:,:-1].values 

point of value have publish

Version 1 is preferable because it is shorter and the compiler will in fact turn it into version 2 - no performance difference whatsoever.

More importantly given we have only 3 properties it might not make a difference, but at what point do you switch from concat to builder?

At the point where you're concatenating in a loop - that's usually when the compiler can't substitute StringBuilder by itself.

Maybe something like this:

import matplotlib.pyplot
import pylab

x = [1,2,3,4]
y = [3,4,8,6]

matplotlib.pyplot.scatter(x,y)

matplotlib.pyplot.show()

EDIT:

Let me see if I understand you correctly now:

You have:

       test1 | test2 | test3
test3 |   1   |   0  |  1

test4 |   0   |   1  |  0

test5 |   1   |   1  |  0

Now you want to represent the above values in in a scatter plot, such that value of 1 is represented by a dot.

Let's say you results are stored in a 2-D list:

results = [[1, 0, 1], [0, 1, 0], [1, 1, 0]]

We want to transform them into two variables so we are able to plot them.

And I believe this code will give you what you are looking for:

import matplotlib
import pylab


results = [[1, 0, 1], [0, 1, 0], [1, 1, 0]]

x = []
y = []

for ind_1, sublist in enumerate(results):
    for ind_2, ele in enumerate(sublist):
        if ele == 1:
            x.append(ind_1)
            y.append(ind_2)       


matplotlib.pyplot.scatter(x,y)

matplotlib.pyplot.show()

Notice that I do need to import pylab, and you would have play around with the axis labels. Also this feels like a work around, and there might be (probably is) a direct method to do this.

Any of the below three options works for you:

echo[

echo(

echo. 

For example:

@echo off
echo There will be a blank line below
echo[
echo Above line is blank
echo( 
echo The above line is also blank.
echo. 
echo The above line is also blank.

Updated Answer for Node.js ~>0.8

Node is able to concatenate buffers on its own now.

var newBuffer = Buffer.concat([buffer1, buffer2]);

Old Answer for Node.js ~0.6

I use a module to add a .concat function, among others:

https://github.com/coolaj86/node-bufferjs

I know it isn't a "pure" solution, but it works very well for my purposes.

A C solution.

int two(int a, int b, int c) {
  return !a + !b + !c < 2;
}

or you may prefer:

int two(int a, int b, int c) {
  return !!a + !!b + !!c >= 2;
}

Please use following php function to convert php stdClass to array

get_object_vars($data)

my problem was this piece of javascript code

$('input').each(function(ele, indx){
    this.value = this.value.toUpperCase();
});

Turns it was messing with viewstate hidden field so I changed it to below code and it worked

$('input:visible').each(function(ele, indx){
    this.value = this.value.toUpperCase();
});

I figured out myself.

cmp calls ComputeBetasAndNuHat which returns a list which has objective as minusloglik

So I can change the function cmp to get this value.

I use following line of code to fix this problem. Write the following code in web.config file

       <jsonSerialization maxJsonLength="50000000"/>
      </webServices>
     </scripting>
   </system.web.extensions>
</configuration>

In Storyboard, select your ViewController and go to Atribute Inspector. At the very top, under Simulated Metrics you have Size and Orientation properties which are set to Inferred. Change them to desired values.

In order for an application to display properly on another screen size, you also have to setup constraints, as described by Can Poyrazoglu in the first post.

There's no prepackaged "do-while", but the general Python way to implement peculiar looping constructs is through generators and other iterators, e.g.:

import itertools

def dowhile(predicate):
  it = itertools.repeat(None)
  for _ in it:
    yield
    if not predicate(): break

so, for example:

i=7; j=3
for _ in dowhile(lambda: i<j):
  print i, j
  i+=1; j-=1

executes one leg, as desired, even though the predicate's already false at the start.

It's normally better to encapsulate more of the looping logic into your generator (or other iterator) -- for example, if you often have cases where one variable increases, one decreases, and you need a do/while loop comparing them, you could code:

def incandec(i, j, delta=1):
  while True:
    yield i, j
    if j <= i: break
    i+=delta; j-=delta

which you can use like:

for i, j in incandec(i=7, j=3):
  print i, j

It's up to you how much loop-related logic you want to put inside your generator (or other iterator) and how much you want to have outside of it (just like for any other use of a function, class, or other mechanism you can use to refactor code out of your main stream of execution), but, generally speaking, I like to see the generator used in a for loop that has little (ideally none) "loop control logic" (code related to updating state variables for the next loop leg and/or making tests about whether you should be looping again or not).

the warning or error of kind IMPLICIT DECLARATION is that the compiler is expecting a Function Declaration/Prototype..

It might either be a header file or your own function Declaration..

use the built in float() function in a list comprehension.

A2 = [float(v.replace('"','').strip()) for v in A1]

Yes. It is possible to draw text in pygame:

# initialize font; must be called after 'pygame.init()' to avoid 'Font not Initialized' error
myfont = pygame.font.SysFont("monospace", 15)

# render text
label = myfont.render("Some text!", 1, (255,255,0))
screen.blit(label, (100, 100))

With regards to @CrazyJugglerDrummer second method it would be:

There is a solution to this that does not require to specify the path of the jar file inside the .bat. This means the jar can be moved around in the filesystem with no changes, as long as the .bat file is always located in the same directory as the jar. The .bat code is:

java -jar %~dp0myjarfile.jar %*

Basically %0 would expand to the .bat full path, and %~dp0 expands to the .bat full path except the filename. So %~dp0myjarfile.jar is the full path of the myjarfile.jar colocated with the .bat file. %* will take all the arguments given to the .bat and pass it to the Java program. (see: http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/percent.mspx?mfr=true )

If you want the server’s default error page to be displayed, you have to handle this in the server.

First of all, don't use char* or char[N]. Use std::string, then everything else becomes so easy!

Examples,

std::string s = "Hello";
std::string greet = s + " World"; //concatenation easy!

Easy, isn't it?

Now if you need char const * for some reason, such as when you want to pass to some function, then you can do this:

some_c_api(s.c_str(), s.size()); 

assuming this function is declared as:

some_c_api(char const *input, size_t length);

Explore std::string yourself starting from here:

• Documentation of std::string

Hope that helps.

2015 Answer: CSS last-of-type allows you to style the last item.

ul li:last-of-type { color: red; }

Rotating the labels is certainly possible. Note though that doing so reduces the readability of the text. One alternative is to alternate label positions using a code like this:

import numpy as np
n=5

x = np.arange(n)
y = np.sin(np.linspace(-3,3,n))
xlabels = ['Long ticklabel %i' % i for i in range(n)]


fig, ax = plt.subplots()
ax.plot(x,y, 'o-')
ax.set_xticks(x)
labels = ax.set_xticklabels(xlabels)
for i, label in enumerate(labels):
    label.set_y(label.get_position()[1] - (i % 2) * 0.075)

For more background and alternatives, see this post on my blog

Here is how I got it to work if you just want to get it back to your first option e.g. "Choose an option" "Select_id_wrap" is obviously the div around the select, but I just want to make that clear just in case it has any bearing on how this works. Mine resets to a click function but I'm sure it will work inside of an on change as well...

$("#select_id_wrap").find("select option").prop("selected", false);

I not expert in MySQL but you probably should look on triggers e.g. BEFORE INSERT. In the trigger you can run select query on your original table and if it found something just update the row 'logins' instead of inserting new values. But all this depends on version of MySQL you running.

Each link has five different states: link, hover, active, focus and visited.

Link is the normal appearance, hover is when you mouse over, active is the state when it's clicked, focus follows active and visited is the state you end up when you unfocus the recently clicked link.

I'm guessing you want to achieve a different style on either focus or visited, then you can add the following CSS:

a { color: #00c; }
a:visited { #ccc; }
a:focus { #cc0; }

A recommended order in your CSS to not cause any trouble is the following:

a
a:visited { ... }
a:focus { ... }
a:hover { ... }
a:active { ... }

You can use your web browser's developer tools to force the states of the element like this (Chrome->Developer Tools/Inspect Element->Style->Filter :hov): Force state in Chrome Developer Tools

By using System.Windows.Forms.Timer class you can achieve what you need.

System.Windows.Forms.Timer t = new System.Windows.Forms.Timer();


t.Interval = 15000; // specify interval time as you want
t.Tick += new EventHandler(timer_Tick);
t.Start();

void timer_Tick(object sender, EventArgs e)
{
      //Call method
}

By using stop() method you can stop timer.

t.Stop();

This is not "wrong" at all, it's just not what the cool guys typically do with MVC. As an aside, I wish some of the early demos of ASP.NET MVC didn't try to cram in Linq-to-Sql at the same time. It's pretty awesome and well suited for MVC, sure, but it's not required. There is nothing about MVC that prevents you from using ADO.NET. For example:

Controller action:

public ActionResult Index()
{
    ViewData["Message"] = "Welcome to ASP.NET MVC!";

    DataTable dt = new DataTable("MyTable");
    dt.Columns.Add(new DataColumn("Col1", typeof(string)));
    dt.Columns.Add(new DataColumn("Col2", typeof(string)));
    dt.Columns.Add(new DataColumn("Col3", typeof(string)));

    for (int i = 0; i < 3; i++)
    {
        DataRow row = dt.NewRow();
        row["Col1"] = "col 1, row " + i;
        row["Col2"] = "col 2, row " + i;
        row["Col3"] = "col 3, row " + i;
        dt.Rows.Add(row);
    }

    return View(dt); //passing the DataTable as my Model
}

View: (w/ Model strongly typed as System.Data.DataTable)

<table border="1">
    <thead>
        <tr>
            <%foreach (System.Data.DataColumn col in Model.Columns) { %>
                <th><%=col.Caption %></th>
            <%} %>
        </tr>
    </thead>
    <tbody>
    <% foreach(System.Data.DataRow row in Model.Rows) { %>
        <tr>
            <% foreach (var cell in row.ItemArray) {%>
                <td><%=cell.ToString() %></td>
            <%} %>
        </tr>
    <%} %>         
    </tbody>
</table>

Now, I'm violating a whole lot of principles and "best-practices" of ASP.NET MVC here, so please understand this is just a simple demonstration. The code creating the DataTable should reside somewhere outside of the controller, and the code in the View might be better isolated to a partial, or html helper, to name a few ways you should do things.

You absolutely are supposed to pass objects to the View, if the view is supposed to present them. (Separation of concerns dictates the view shouldn't be responsible for creating them.) In this case I passed the DataTable as the actual view Model, but you could just as well have put it in ViewData collection. Alternatively you might make a specific IndexViewModel class that contains the DataTable and other objects, such as the welcome message.

I hope this helps!

There's no need for a method here.

HTML

<div v-if="active">
    <h2>Hello World!</h2>
 </div>

 <div v-on:mouseover="active = !active">
    <h1>Hover me!</h1>
 </div>

JS

new Vue({
  el: 'body',
  data: {
    active: false
  }
})

In case of proxy the SERVER_PORT may not give the correct value so this is what worked for me -

$protocol = ((!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] != 'off') || $_SERVER['SERVER_PORT'] == 443 || $_SERVER['HTTP_X_FORWARDED_PORT'] == 443) ? "https://" : "http://"

If your DB is password protected, then the solution would be:

PGPASSWORD=password  psql -U username -d dbname -c "select * from my_table"

If you have GNU find you can also say

find . -newermt '1 minute ago'

The t options makes the reference "file" for newer become a reference date string of the sort that you could pass to GNU date -d, which understands complex date specifications like the one given above.

Remove the z-index value.

I would also recommend this approach.

HTML:

<header class="main-header" role="banner">
  <img src="mybannerimage.gif" alt="Banner Image"/>
</header>

CSS:

.main-header {
  text-align: center;
}

This will center your image with out stretching it out. You can adjust the padding as needed to give it some space around your image. Since this is at the top of your page you don't need to force it there with position absolute unless you want your other elements to go underneath it. In that case you'd probably want position:fixed; anyway.

You cannot show an alert from a controller. There is one way communication from the client to the server.The server can therefore not tell the client to do anything. The client requests and the server gives a response.

You therefore need to use javascript when the response returns to show a messagebox of some sort.

OR

using jquery on the button that calls the controller action

<script>
 $(document).ready(function(){
  $("#submitButton").on("click",function()
  {
   alert('Your Message');
  });

});
<script>

When you want a flex item to occupy an entire row, set it to width: 100% or flex-basis: 100%, and enable wrap on the container.

The item now consumes all available space. Siblings are forced on to other rows.

.parent {
  display: flex;
  flex-wrap: wrap;
}

#range, #text {
  flex: 1;
}

.error {
  flex: 0 0 100%; /* flex-grow, flex-shrink, flex-basis */
  border: 1px dashed black;
}

<div class="parent">
  <input type="range" id="range">
  <input type="text" id="text">
  <label class="error">Error message (takes full width)</label>
</div>

More info: The initial value of the flex-wrap property is nowrap, which means that all items will line up in a row. MDN

Update 10/11/2020 to reflect the latest brew changes.

Brew already provide a command to uninstall itself (this will remove everything you installed with Homebrew):

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall.sh)"

If you failed to run this command due to permission (like run as second user), run again with sudo

Then you can install again:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

There are many answers, but you should just be able to keep it simple. Make sure you know what port SSH is listening on, and define it. Here is what I just used to replicate your problem.

scp -P 12222 file.7z [email protected]:/home/user/Downloads It worked out well.

For me, removing WebDAV from my server caused the application to return a 503 Service Unavailable Error message when using PUT or DELETE, so I re-installed it back again. I also tried completely removing .NET Framework 4.5 and reinstalling it and also tried re-registering as suggested but to no avail.

I was able to fix this by disabling WebDAV for the individual application pool, this stopped the 'bad module' error when using PUT or DELETE.

Disable WebDAV for Individual App Pool:

1. Click the affected application pool
2. Find WebDAV Authoring Tools in the list
3. Click to open it
4. Click Disable WebDAV in the top right.

Ta daaaa!

I still left the remove items in my web.config file.

 <system.webServer>
    <modules>
      <remove name="WebDAVModule"/>
    </modules>
    <handlers>
      <remove name="WebDAV" />
    </handlers>
 <system.webServer>

This link is where I found the instructions but it's not very clear.

Uncheck

"Work Offline"

in Settings -> Maven ! It worked for me ! :D

Simple Example:

break leaves the loop.

int m = 0;
for(int n = 0; n < 5; ++n){
  if(n == 2){
    break;
  }
  m++;
}

System.out.printl("m:"+m); // m:2

continue will go back to start loop.

int m = 0;
for(int n = 0; n < 5; ++n){
  if(n == 2){
    continue; // Go back to start and dont execute m++
  }
  m++;
}

System.out.printl("m:"+m); // m:4

DateTime date = DateTime.now().withTimeAtStartOfDay();
date.toString("HH:mm:ss")

I had the same problem when I was writing Java application on Netbeans.Here is the solution:

1. Find your project in projects selection tab

2. Right click "Libraries"

3. Click "Add JAR/Folder..."

4. Choose "derbyclient.jar"

5. Click "Open", then you will see "derbyclient.jar" under your "Libraries"

6. Make sure your URL, user name, pass word is correct, and run your code:)

Thank you All...

My issue solved by below code:

An alternative to using keytool, you can use the command

openssl x509 -in certificate.pem -text

This should work for any x509 .pem file provided you have openssl installed.

Rather than using booleans, why not just set the button to false when its clicked, so you do that in your actionPerformed method. Its more efficient..

if (command.equals("w"))
{
    FileConverter fc = new FileConverter();
    btnConvertDocuments.setEnabled(false);
}

In case you develop applications for Android you should try out the TimingLogger class.
Take a look at these articles describing the usage of the TimingLogger helper class:

• Measuring performance in the Android SDK (27.09.2010)
• Discovering the Android API - Part 1 (03.01.2017)

I think, in finally that this is the best solution, easy and simple:

img {
    display: block;
    max-width: 100%;
    max-height: 100%;
    width: auto;
    height: auto;
}

If all you want is the POST request body, you could use a method like this:

static String extractPostRequestBody(HttpServletRequest request) throws IOException {
    if ("POST".equalsIgnoreCase(request.getMethod())) {
        Scanner s = new Scanner(request.getInputStream(), "UTF-8").useDelimiter("\\A");
        return s.hasNext() ? s.next() : "";
    }
    return "";
}

The simplest way is using libraries like google-http-java-client but if you want parse the JSON response by yourself you can do that in a multiple ways, you can use org.json, json-simple, Gson, minimal-json, jackson-mapper-asl (from 1.x)... etc

A set of simple examples:

Using Gson:

import java.io.IOException;

import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.util.EntityUtils;

public class Gson {

    public static void main(String[] args) {
    }

    public HttpResponse http(String url, String body) {

        try (CloseableHttpClient httpClient = HttpClientBuilder.create().build()) {
            HttpPost request = new HttpPost(url);
            StringEntity params = new StringEntity(body);
            request.addHeader("content-type", "application/json");
            request.setEntity(params);
            HttpResponse result = httpClient.execute(request);
            String json = EntityUtils.toString(result.getEntity(), "UTF-8");

            com.google.gson.Gson gson = new com.google.gson.Gson();
            Response respuesta = gson.fromJson(json, Response.class);

            System.out.println(respuesta.getExample());
            System.out.println(respuesta.getFr());

        } catch (IOException ex) {
        }
        return null;
    }

    public class Response{

        private String example;
        private String fr;

        public String getExample() {
            return example;
        }
        public void setExample(String example) {
            this.example = example;
        }
        public String getFr() {
            return fr;
        }
        public void setFr(String fr) {
            this.fr = fr;
        }
    }
}

Using json-simple:

import java.io.IOException;

import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.util.EntityUtils;
import org.json.simple.JSONArray;
import org.json.simple.JSONObject;
import org.json.simple.parser.JSONParser;

public class JsonSimple {

    public static void main(String[] args) {

    }

    public HttpResponse http(String url, String body) {

        try (CloseableHttpClient httpClient = HttpClientBuilder.create().build()) {
            HttpPost request = new HttpPost(url);
            StringEntity params = new StringEntity(body);
            request.addHeader("content-type", "application/json");
            request.setEntity(params);
            HttpResponse result = httpClient.execute(request);

            String json = EntityUtils.toString(result.getEntity(), "UTF-8");
            try {
                JSONParser parser = new JSONParser();
                Object resultObject = parser.parse(json);

                if (resultObject instanceof JSONArray) {

                        System.out.println(obj.get("example"));
                        System.out.println(obj.get("fr"));
                    }

                }else if (resultObject instanceof JSONObject) {
                    JSONObject obj =(JSONObject)resultObject;
                    System.out.println(obj.get("example"));
                    System.out.println(obj.get("fr"));

        } catch (IOException ex) {

        return null;
    }

In Android Studio 3 and Above, both for Windows, Mac and Linux:

File -> Sync Project with Gradle Files

Solved!

Or you can do this by shortcut key:

Press ? + Shift + A (Mac) or Ctrl+Shift+A (Windows, Linux). Then pop-up a Edit-Text and write "Sync Project with Gradle Files". Then press double click on the option.

Your problem solved! It'll sync your gradle file with your project file, thanks.

Screenshot:

There isn't a need for _.map or _.pluck since ES6 has taken off.

Here's an alternative using ES6 JavaScript:

clips.map(clip => clip.id)

Using Find or FindIndex methods of the Array class:

if(Array.Find(stringArray, stringToCheck.Contains) != null) 
{ 
}

if(Array.FindIndex(stringArray, stringToCheck.Contains) != -1) 
{ 
}

for l in list1:
    val = 50 - l[0] + l[1] - l[2]
    print "val:", val

Loop through list and do operation on the sublist as you wanted.

$('.formData').attr('value','YOUR_VALUE')

If an URL pattern starts with /, then it's relative to the context root. The /Admin/* URL pattern would only match pages on http://localhost:8080/EMS2/Admin/* (assuming that /EMS2 is the context path), but you have them actually on http://localhost:8080/EMS2/faces/Html/Admin/*, so your URL pattern never matches.

You need to prefix your URL patterns with /faces/Html as well like so:

<url-pattern>/faces/Html/Admin/*</url-pattern>

You can alternatively also just reconfigure your web project structure/configuration so that you can get rid of the /faces/Html path in the URLs so that you can just open the page by for example http://localhost:8080/EMS2/Admin/Upload.xhtml.

Your filter mapping syntax is all fine. However, a simpler way to specify multiple URL patterns is to just use only one <filter-mapping> with multiple <url-pattern> entries:

<filter-mapping>
    <filter-name>LoginFilter</filter-name>
    <url-pattern>/faces/Html/Employee/*</url-pattern>
    <url-pattern>/faces/Html/Admin/*</url-pattern>
    <url-pattern>/faces/Html/Supervisor/*</url-pattern>
</filter-mapping>

If you run your playbook with ansible-playbook -vvv you'll see the actual command being run, so you can check whether the key is actually being included in the ssh command (and you might discover that the problem was the wrong username rather than the missing key).

I agree with Brian's comment above (and zigam's edit) that the vars section is too late. I also tested including the key in the on-the-fly definition of the host like this

# fails
- name: Add all instance public IPs to host group
  add_host: hostname={{ item.public_ip }} groups=ec2hosts ansible_ssh_private_key_file=~/.aws/dev_staging.pem
  loop: "{{ ec2.instances }}"

but that fails too.

So this is not an answer. Just some debugging help and things not to try.

The simplest way:

ping hostname

e.g.

ping dynlab938.meng.auth.gr

it will print: Pinging dynlab938.meng.auth.gr [155.207.29.38] with 32 bytes of data

Your problem is that Python is looking in the Python directory for this file and not finding it. You must specify that you are talking about the directory that you are in and not the Python one.

To do this you change this:

from application.app.folder.file import func_name

to this:

from .application.app.folder.file import func_name

By adding the dot you are saying look in this folder for the application folder instead of looking in the Python directory.

Since Entity Framework 5.0 you can use following code in order to solve your issue:

public abstract class YourContext : DbContext
{
  public YourContext()
  {
    (this as IObjectContextAdapter).ObjectContext.ContextOptions.UseCSharpNullComparisonBehavior = true;
  }
}

This should solve your problems as Entity Framerwork will use 'C# like' null comparison.

I had a similar use case during testing hibernate event listeners which are only called on commit.

The solution was to wrap the code to be persistent into another method annotated with REQUIRES_NEW. (In another class) This way a new transaction is spawned and a flush/commit is issued once the method returns.

Keep in mind that this might influence all the other tests! So write them accordingly or you need to ensure that you can clean up after the test ran.

if using logging.config.fileConfig with a configuration file use something like:

[formatter_simpleFormatter]
format=%(asctime)s - %(name)s - %(levelname)s - %(message)s
datefmt=%Y-%m-%d %H:%M:%S

With scss:

$btn-focus-box-shadow: none!important;

TCP sockets remain open till they are closed.

That said, it's very difficult to detect a broken connection (broken, as in a router died, etc, as opposed to closed) without actually sending data, so most applications do some sort of ping/pong reaction every so often just to make sure the connection is still actually alive.

Just to be clear, you are wanting to launch a program from a batch file and then have the batch file press keys (in your example, the arrow keys) within that launched program?

If that is the case, you aren't going to be able to do that with simply a ".bat" file as the launched would stop the batch file from continuing until it terminated--

My first recommendation would be to use something like AutoHotkey or AutoIt if possible, simply because they both have active forums where you'd find countless examples of people launching applications and sending key presses not to mention tools to simply "record" what you want to do. However you said this is a work computer and you may not be able to load a 3rd party program.. but you aren't without options.

You can use Windows Scripting Host from something like a .vbs file to launch a program and send keys to that process. If you're running a version of Windows that includes PowerShell 2.0 (Windows XP with Service Pack 3, Windows Vista with Service Pack 1, Windows 7, etc.) you can use Windows Scripting Host as a COM object from your PS script or use VB's Intereact class.

The specifics of how to do it are outside the scope of this answer but you can find numerous examples using the methods I just described by searching on SO or Google.

edit: Just to help you get started you can look here:

1. Automate tasks with Windows Script Host's SendKeys method
2. A useful thread about SendKeys

I could "automate" it with a call to:

def __fix_io_encoding(last_resort_default='UTF-8'):
  import sys
  if [x for x in (sys.stdin,sys.stdout,sys.stderr) if x.encoding is None] :
      import os
      defEnc = None
      if defEnc is None :
        try:
          import locale
          defEnc = locale.getpreferredencoding()
        except: pass
      if defEnc is None :
        try: defEnc = sys.getfilesystemencoding()
        except: pass
      if defEnc is None :
        try: defEnc = sys.stdin.encoding
        except: pass
      if defEnc is None :
        defEnc = last_resort_default
      os.environ['PYTHONIOENCODING'] = os.environ.get("PYTHONIOENCODING",defEnc)
      os.execvpe(sys.argv[0],sys.argv,os.environ)
__fix_io_encoding() ; del __fix_io_encoding

Yes, it's possible to get an infinite loop here if this "setenv" fails.

I don't know this particular library, but I've used very similar calls. So this is my best guess:

unsigned char digest[16];
const char* string = "Hello World";
struct MD5Context context;
MD5Init(&context);
MD5Update(&context, string, strlen(string));
MD5Final(digest, &context);

This will give you back an integer representation of the hash. You can then turn this into a hex representation if you want to pass it around as a string.

char md5string[33];
for(int i = 0; i < 16; ++i)
    sprintf(&md5string[i*2], "%02x", (unsigned int)digest[i]);

This is a nice python example

def walk_with_depth(root_path, depth):
        if depth < 0:
            for root, dirs, files in os.walk(root_path):
                yield [root, dirs[:], files]

            return

        elif depth == 0:
            return

        base_depth = root_path.rstrip(os.path.sep).count(os.path.sep)
        for root, dirs, files in os.walk(root_path):
            yield [root, dirs[:], files]

            cur_depth = root.count(os.path.sep)
            
            if base_depth + depth <= cur_depth:
                del dirs[:]

@Marc B Thanks for the comment. Helped me discover this:

<?php if ( have_posts() ) : while ( have_posts() ) : the_post();

You can convert a string to a DATE using the TO_DATE function, then reformat the date as another string using TO_CHAR, i.e.:

SELECT TO_CHAR(
         TO_DATE('15/August/2009,4:30 PM'
                ,'DD/Month/YYYY,HH:MI AM')
       ,'DD-MM-YYYY')
FROM DUAL;

15-08-2009

For example, if your table name is MYTABLE and the varchar2 column is MYDATESTRING:

SELECT TO_CHAR(
         TO_DATE(MYDATESTRING
                ,'DD/Month/YYYY,HH:MI AM')
       ,'DD-MM-YYYY')
FROM MYTABLE;

For Googlers:

Here is why:

• Simple request, or, GET/POST with no cookies do not trigger preflight
• When you configure CORS for a path, API Gateway will only create an OPTIONS method for that path, then send Allow-Origin headers using mock responses when user calls OPTIONS, but GET / POST will not get Allow-Origin automatically
• If you try to send simple requests with CORS mode on, you will get an error because that response has no Allow-Origin header
• You may adhere to best practice, simple requests are not meant to send response to user, send authentication/cookie along with your requests to make it "not simple" and preflight will trigger
• Still, you will have to send CORS headers by yourself for the request following OPTIONS

To sum it up:

• Only harmless OPTIONS will be generated by API Gateway automatically
• OPTIONS are only used by browser as a precautious measure to check possibility of CORS on a path
• Whether CORS is accepted depend on the actual method e.g. GET / POST
• You have to manually send appropriate headers in your response

From the documentation:

If the pattern does not contain a slash /, git treats it as a shell glob pattern and checks for a match against the pathname relative to the location of the .gitignore file (relative to the toplevel of the work tree if not from a .gitignore file).

A leading slash matches the beginning of the pathname. For example, "/*.c" matches "cat-file.c" but not "mozilla-sha1/sha1.c".

So you should add the following line to your root .gitignore:

/config.php

The minimum requirements are based on the Express edition you're attempting to install:

Express for Web (Web sites and HTML5 applications) - Windows 7 SP1 (With IE 10)
Express for Windows (Windows 8 Apps) - Windows 8.1
Express for Windows Desktop (Windows Programs) - Windows 7 SP1 (With IE 10)
Express for Windows Phone (Windows Phone Apps) - Windows 8

It sounds like you're trying to install the "Express 2013 for Windows" edition, which is for developing Windows 8 "Modern UI" apps, or the Windows Phone edition.

The similarly named version that is compatible with Windows 7 SP1 is "Express 2013 for Windows Desktop"

It's a verbatim string literal. It means that escaping isn't applied. For instance:

string verbatim = @"foo\bar";
string regular = "foo\\bar";

Here verbatim and regular have the same contents.

It also allows multi-line contents - which can be very handy for SQL:

string select = @"
SELECT Foo
FROM Bar
WHERE Name='Baz'";

The one bit of escaping which is necessary for verbatim string literals is to get a double quote (") which you do by doubling it:

string verbatim = @"He said, ""Would you like some coffee?"" and left.";
string regular = "He said, \"Would you like some coffee?\" and left.";

Slightly more generic version of what @mark_s posted, this helped me

SELECT 
'ALTER TABLE ' +  OBJECT_SCHEMA_NAME(k.parent_object_id) +
'.[' + OBJECT_NAME(k.parent_object_id) + 
'] DROP CONSTRAINT ' + k.name
FROM sys.foreign_keys k
WHERE referenced_object_id = object_id('your table')

just plug your table name, and execute the result of it.

Not exactly what asked but quite helpful

declare -u foo #When the variable is assigned a value, all lower-case characters are converted to upper-case.

foo=bar
echo $foo
BAR

And the opposite

declare -l foo #When the variable is assigned a value, all upper-case characters are converted to lower-case.

foo=BAR
echo $foo
bar

You have to run the development server such that it listens on the interface to your network.

E.g.

python manage.py runserver 0.0.0.0:8000

listens on every interface on port 8000.

It doesn't matter whether you access the webserver with the IP or the hostname. I guess you are still in your own LAN.
If you really want to access the server from outside, you also have to configure your router to forward port e.g. 8000 to your server.

Check your firewall on your server whether incoming connections to the port in use are allowed!

Assuming you can access your Apache server from the outside successfully, you can also try this:

• Stop the Apache server, so that port 80 is free.
• Start the development server with sudo python manage.py runserver 0.0.0.0:80

Please try this

SELECT *
FROM   [Village]
WHERE  CONVERT(VARCHAR, CastleType) = 'foo'

It is used to influence sorting in the CSS cascade when sorting by origin is done. It has nothing to do with specificity like stated here in other answers.

Here is the priority from lowest to highest:

1. browser styles
2. user style sheet declarations (without !important)
3. author style sheet declarations (without !important)
4. !important author style sheets
5. !important user style sheets

After that specificity takes place for the rules still having a finger in the pie.

In the simple setup you are likely using, getchar works with buffered input, so you have to press enter before getchar gets anything to read. Strings are not terminated by EOF; in fact, EOF is not really a character, but a magic value that indicates the end of the file. But EOF is not part of the string read. It's what getchar returns when there is nothing left to read.

I don't know about performance difference, but as you say, static nested class is not a part of an instance of the enclosing class. Seems just simpler to create a static nested class unless you really need it to be an inner class.

It's a bit like why I always make my variables final in Java - if they're not final, I know there's something funny going on with them. If you use an inner class instead of a static nested class, there should be a good reason.

You can do this:

String aToString = java.util.Arrays.toString(anArray);
// Do not need to do this if you are OK with '[' and ']'
aToString = aToString.substring(1, aToString.length() - 1);

Or a one-liner (only when you do not want '[' and ']')

String aToString = java.util.Arrays.toString(anArray).substring(1).replaceAll("\\]$", "");

Hope this helps.

If you are starting IPython with the --pylab option, you shouldn't need to call show() or draw(). Try this:

ipython  --pylab=inline

A short example will help you understand one of yield from's use case: get value from another generator

def flatten(sequence):
    """flatten a multi level list or something
    >>> list(flatten([1, [2], 3]))
    [1, 2, 3]
    >>> list(flatten([1, [2], [3, [4]]]))
    [1, 2, 3, 4]
    """
    for element in sequence:
        if hasattr(element, '__iter__'):
            yield from flatten(element)
        else:
            yield element

print(list(flatten([1, [2], [3, [4]]])))

STATICFILES_DIRS: You can keep the static files for your project here e.g. the ones used by your templates.

STATIC_ROOT: leave this empty, when you do manage.py collectstatic, it will search for all the static files on your system and move them here. Your static file server is supposed to be mapped to this folder wherever it is located. Check it after running collectstatic and you'll find the directory structure django has built.

--------Edit----------------

As pointed out by @DarkCygnus, STATIC_ROOT should point at a directory on your filesystem, the folder should be empty since it will be populated by Django.

STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles')

or

STATIC_ROOT = '/opt/web/project/static_files'

--------End Edit -----------------

STATIC_URL: '/static/' is usually fine, it's just a prefix for static files.

List<string> SplitString(int chunk, string input)
{
    List<string> list = new List<string>();
    int cycles = input.Length / chunk;

    if (input.Length % chunk != 0)
        cycles++;

    for (int i = 0; i < cycles; i++)
    {
        try
        {
            list.Add(input.Substring(i * chunk, chunk));
        }
        catch
        {
            list.Add(input.Substring(i * chunk));
        }
    }
    return list;
}

Swift 4:

self .yourButton(self)

I see a lot of "px" discussion but no one is talking percentages which is the fixed number you want to calculate by.

22.37% is the key percentage here. Multiply any of the image sizes mentioned above in by 0.2237 and you will get the correct pixel radius for that size.

Before iOS 8, Apple used less rounding, using 15.625%.

EDIT: Thanks @Chris Prince for commenting with the iOS 8/9/10 radius percentage: 22.37%

if you want both width and the height you can try

 background-size: cover !important;

but this wont distort the image but fill the div.

The Swift version from String to Data and back to String:

Xcode 10.1 • Swift 4.2.1

extension Data {
    var string: String? {
        return String(data: self, encoding: .utf8)
    }
}

extension StringProtocol {
    var data: Data {
        return Data(utf8)
    }
}

extension String {
    var base64Decoded: Data? {
        return Data(base64Encoded: self)
    }
}

Playground

let string = "Hello World"                                  // "Hello World"
let stringData = string.data                                // 11 bytes
let base64EncodedString = stringData.base64EncodedString()  // "SGVsbG8gV29ybGQ="
let stringFromData = stringData.string                      // "Hello World"

let base64String = "SGVsbG8gV29ybGQ="
if let data = base64String.base64Decoded {
    print(data)                                    //  11 bytes
    print(data.base64EncodedString())              // "SGVsbG8gV29ybGQ="
    print(data.string ?? "nil")                    // "Hello World"
}

let stringWithAccent = "Olá Mundo"                          // "Olá Mundo"
print(stringWithAccent.count)                               // "9"
let stringWithAccentData = stringWithAccent.data            // "10 bytes" note: an extra byte for the acute accent
let stringWithAccentFromData = stringWithAccentData.string  // "Olá Mundo\n"

You can also initialize data members at the point you declare them:

class another_example{
public:
    another_example();
    ~another_example();
private:
    int m_iInteger=10;
    double m_dDouble=10.765;
};

I use this form pretty much exclusively, although I have read some people consider it 'bad form', perhaps because it was only recently introduced - I think in C++11. To me it is more logical.

Another useful facet to the new rules is how to initialize data-members that are themselves classes. For instance suppose that CDynamicString is a class that encapsulates string handling. It has a constructor that allows you specify its initial value CDynamicString(wchat_t* pstrInitialString). You might very well use this class as a data member inside another class - say a class that encapsulates a windows registry value which in this case stores a postal address. To 'hard code' the registry key name to which this writes you use braces:

class Registry_Entry{
public:
    Registry_Entry();
    ~Registry_Entry();
    Commit();//Writes data to registry.
    Retrieve();//Reads data from registry;
private:
    CDynamicString m_cKeyName{L"Postal Address"};
    CDynamicString m_cAddress;
};

Note the second string class which holds the actual postal address does not have an initializer so its default constructor will be called on creation - perhaps automatically setting it to a blank string.

I believe you also have to use .detach(). I had to convert my Tensor to a numpy array on Colab which uses CUDA and GPU. I did it like the following:

# this is just my embedding matrix which is a Torch tensor object
embedding = learn.model.u_weight

embedding_list = list(range(0, 64382))

input = torch.cuda.LongTensor(embedding_list)
tensor_array = embedding(input)
# the output of the line below is a numpy array
tensor_array.cpu().detach().numpy()

Here's a function to pretty up your json: pretty_json

First way is

function function1()
{
  var variable1=12;
  function2(variable1);
}

function function2(val)
{
  var variableOfFunction1 = val;

// Then you will have to use this function for the variable1 so it doesn't really help much unless that's what you want to do. }

Second way is

var globalVariable;
function function1()
{
  globalVariable=12;
  function2();
}

function function2()
{
  var local = globalVariable;
}

ul li + li:before
{
    content:url(imgs/separator.gif);
}

Just an FYI, clearer, more readable syntax IMHO

"use strict";
String.prototype.pad = function( len, c, left ) {
    var s = '',
        c = ( c || ' ' ),
        len = Math.max( len, 0 ) - this.length,
        left = ( left || false );
    while( s.length < len ) { s += c };
    return ( left ? ( s + this ) : ( this + s ) );
}
Number.prototype.pad = function( len, c, left ) {
    return String( this ).pad( len, c, left );
}
Number.prototype.lZpad = function( len ) {
    return this.pad( len, '0', true );
}

This also results in less visual and readability glitches of the results than some of the other solutions, which enforce '0' as a character; answering my questions what do I do if I want to pad other characters, or on the other direction (right padding), whilst remaining easy to type, and clear to read. Pretty sure it's also the DRY'est example, with the least code for the actual leading-zero-padding function body (as the other dependent functions are largely irrelevant to the question).

The code is available for comment via gist from this github user (original source of the code) https://gist.github.com/Lewiscowles1986/86ed44f428a376eaa67f

A note on console & script testing, numeric literals seem to need parenthesis, or a variable in order to call methods, so 2.pad(...) will cause an error, whilst (2).pad(0,'#') will not. This is the same for all numbers it seems

In first activity u can send intent using startActivityForResult() and then get result from second activity after it finished using setResult.

MainActivity.class

public class MainActivity extends AppCompatActivity {

    private static final int SECOND_ACTIVITY_RESULT_CODE = 0;

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

    // "Go to Second Activity" button click
    public void onButtonClick(View view) {

        // Start the SecondActivity
        Intent intent = new Intent(this, SecondActivity.class);
        // send intent for result 
        startActivityForResult(intent, SECOND_ACTIVITY_RESULT_CODE);
    }

    // This method is called when the second activity finishes
    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        // check that it is the SecondActivity with an OK result
        if (requestCode == SECOND_ACTIVITY_RESULT_CODE) {
            if (resultCode == RESULT_OK) {

                // get String data from Intent
                String returnString = data.getStringExtra("keyName");

                // set text view with string
                TextView textView = (TextView) findViewById(R.id.textView);
                textView.setText(returnString);
            }
        }
    }
}

SecondActivity.class

public class SecondActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

    // "Send text back" button click
    public void onButtonClick(View view) {

        // get the text from the EditText
        EditText editText = (EditText) findViewById(R.id.editText);
        String stringToPassBack = editText.getText().toString();

        // put the String to pass back into an Intent and close this activity
        Intent intent = new Intent();
        intent.putExtra("keyName", stringToPassBack);
        setResult(RESULT_OK, intent);

You can pass the format in to the ToString method, e.g.:

myFloatVariable.ToString("0.00"); //2dp Number

myFloatVariable.ToString("n2"); // 2dp Number

myFloatVariable.ToString("c2"); // 2dp currency

Good existing answers, some of which I used to come up with my own:

I have to get the path from URIs and get the URI from paths, and Google has a hard time telling the difference so for anyone who has the same issue (e.g., to get the thumbnail from the MediaStore of a video whose physical location you already have). The former:

/**
 * Gets the corresponding path to a file from the given content:// URI
 * @param selectedVideoUri The content:// URI to find the file path from
 * @param contentResolver The content resolver to use to perform the query.
 * @return the file path as a string
 */
private String getFilePathFromContentUri(Uri selectedVideoUri,
        ContentResolver contentResolver) {
    String filePath;
    String[] filePathColumn = {MediaColumns.DATA};

    Cursor cursor = contentResolver.query(selectedVideoUri, filePathColumn, null, null, null);
    cursor.moveToFirst();

    int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
    filePath = cursor.getString(columnIndex);
    cursor.close();
    return filePath;
}

The latter (which I do for videos, but can also be used for Audio or Files or other types of stored content by substituting MediaStore.Audio (etc) for MediaStore.Video):

/**
 * Gets the MediaStore video ID of a given file on external storage
 * @param filePath The path (on external storage) of the file to resolve the ID of
 * @param contentResolver The content resolver to use to perform the query.
 * @return the video ID as a long
 */
private long getVideoIdFromFilePath(String filePath,
        ContentResolver contentResolver) {


    long videoId;
    Log.d(TAG,"Loading file " + filePath);

            // This returns us content://media/external/videos/media (or something like that)
            // I pass in "external" because that's the MediaStore's name for the external
            // storage on my device (the other possibility is "internal")
    Uri videosUri = MediaStore.Video.Media.getContentUri("external");

    Log.d(TAG,"videosUri = " + videosUri.toString());

    String[] projection = {MediaStore.Video.VideoColumns._ID};

    // TODO This will break if we have no matching item in the MediaStore.
    Cursor cursor = contentResolver.query(videosUri, projection, MediaStore.Video.VideoColumns.DATA + " LIKE ?", new String[] { filePath }, null);
    cursor.moveToFirst();

    int columnIndex = cursor.getColumnIndex(projection[0]);
    videoId = cursor.getLong(columnIndex);

    Log.d(TAG,"Video ID is " + videoId);
    cursor.close();
    return videoId;
}

Basically, the DATA column of MediaStore (or whichever sub-section of it you're querying) stores the file path, so you either use what you know to look up that DATA field, or use the field to look up whatever else you want.

I then further use the Scheme as above to figure out what to do with my data:

 private boolean  getSelectedVideo(Intent imageReturnedIntent, boolean fromData) {

    Uri selectedVideoUri;

    //Selected image returned from another activity
            // A parameter I pass myself to know whether or not I'm being "shared via" or
            // whether I'm working internally to my app (fromData = working internally)
    if(fromData){
        selectedVideoUri = imageReturnedIntent.getData();
    } else {
        //Selected image returned from SEND intent 
                    // which I register to receive in my manifest
                    // (so people can "share via" my app)
        selectedVideoUri = (Uri)getIntent().getExtras().get(Intent.EXTRA_STREAM);
    }

    Log.d(TAG,"SelectedVideoUri = " + selectedVideoUri);

    String filePath;

    String scheme = selectedVideoUri.getScheme(); 
    ContentResolver contentResolver = getContentResolver();
    long videoId;

    // If we are sent file://something or content://org.openintents.filemanager/mimetype/something...
    if(scheme.equals("file") || (scheme.equals("content") && selectedVideoUri.getEncodedAuthority().equals("org.openintents.filemanager"))){

        // Get the path
        filePath = selectedVideoUri.getPath();

        // Trim the path if necessary
        // openintents filemanager returns content://org.openintents.filemanager/mimetype//mnt/sdcard/xxxx.mp4
        if(filePath.startsWith("/mimetype/")){
            String trimmedFilePath = filePath.substring("/mimetype/".length());
            filePath = trimmedFilePath.substring(trimmedFilePath.indexOf("/"));
        }

        // Get the video ID from the path
        videoId = getVideoIdFromFilePath(filePath, contentResolver);

    } else if(scheme.equals("content")){

        // If we are given another content:// URI, look it up in the media provider
        videoId = Long.valueOf(selectedVideoUri.getLastPathSegment());
        filePath = getFilePathFromContentUri(selectedVideoUri, contentResolver);

    } else {
        Log.d(TAG,"Failed to load URI " + selectedVideoUri.toString());
        return false;
    }

     return true;
 }

empty is an operator:

The empty operator is a prefix operation that can be used to determine whether a value is null or empty.

Ultimately you want to review the datetime documentation and become familiar with the formatting variables, but here are some examples to get you started:

import datetime

print('Timestamp: {:%Y-%m-%d %H:%M:%S}'.format(datetime.datetime.now()))
print('Timestamp: {:%Y-%b-%d %H:%M:%S}'.format(datetime.datetime.now()))
print('Date now: %s' % datetime.datetime.now())
print('Date today: %s' % datetime.date.today())

today = datetime.date.today()
print("Today's date is {:%b, %d %Y}".format(today))

schedule = '{:%b, %d %Y}'.format(today) + ' - 6 PM to 10 PM Pacific'
schedule2 = '{:%B, %d %Y}'.format(today) + ' - 1 PM to 6 PM Central'
print('Maintenance: %s' % schedule)
print('Maintenance: %s' % schedule2)

The output:

Timestamp: 2014-10-18 21:31:12

Timestamp: 2014-Oct-18 21:31:12

Date now: 2014-10-18 21:31:12.318340

Date today: 2014-10-18

Today's date is Oct, 18 2014

Maintenance: Oct, 18 2014 - 6 PM to 10 PM Pacific

Maintenance: October, 18 2014 - 1 PM to 6 PM Central

While all the answers given so far are perfectly valid, one should also keep in mind the google reflections library for a more generic and easy approach to annotation scanning, e.g.

 Reflections reflections = new Reflections("my.project.prefix");

 Set<Field> ids = reflections.getFieldsAnnotatedWith(javax.persistence.Id.class);

data = (['President','George','Bush','is','.'],['O','B-PERSON','I-PERSON','O','O'])
corpus = []
for(doc,tags) in data:
    doc_tag = []
    for word,tag in zip(doc,tags):
        doc_tag.append((word,tag))
        corpus.append(doc_tag)
        print(corpus)

I know this is an old question but I'm astonished that a rather obvious and disgusting hack isn't here.

You can exploit the ability to define your own ctor function to grab necessary values out of your services as you define them... obviously this would be ran every time the service was requested unless you explicitly remove/clear and re-add the definition of this service within the first construction of the exploiting ctor.

This method has the advantage of not requiring you to build the service tree, or use it, during the configuration of the service. You are still defining how services will be configured.

public void ConfigureServices(IServiceCollection services)
{
    //Prey this doesn't get GC'd or promote to a static class var
    string? somevalue = null;

    services.AddSingleton<IServiceINeedToUse, ServiceINeedToUse>(scope => {
         //create service you need
         var service = new ServiceINeedToUse(scope.GetService<IDependantService>())
         //get the values you need
         somevalue = somevalue ?? service.MyDirtyHack();
         //return the instance
         return service;
    });
    services.AddTransient<IOtherService, OtherService>(scope => {
         //Explicitly ensuring the ctor function above is called, and also showcasing why this is an anti-pattern.
         scope.GetService<IServiceINeedToUse>();
         //TODO: Clean up both the IServiceINeedToUse and IOtherService configuration here, then somehow rebuild the service tree.
         //Wow!
         return new OtherService(somevalue);
    });
}

The way to fix this pattern would be to give OtherService an explicit dependency on IServiceINeedToUse, rather than either implicitly depending on it or its method's return value... or resolving that dependency explicitly in some other fashion.

This line

mnuActionLanguage.ComboBox.DisplayMember = "Lang.Language";

is wrong. Change it to

mnuActionLanguage.ComboBox.DisplayMember = "Language";

and it will work (even without DataBind()).

Add as first row or last row in a table

To add as first row in table

$(".table tbody").append("<tr><td>New row</td></tr>");

To add as last row in table

$(".table tbody").prepend("<tr><td>New row</td></tr>");

A practical example when name() and toString() make sense to be different is a pattern where single-valued enum is used to define a singleton. It looks surprisingly at first but makes a lot of sense:

enum SingletonComponent {
    INSTANCE(/*..configuration...*/);

    /* ...behavior... */

    @Override
    String toString() {
      return "SingletonComponent"; // better than default "INSTANCE"
    }
}

In such case:

SingletonComponent myComponent = SingletonComponent.INSTANCE;
assertThat(myComponent.name()).isEqualTo("INSTANCE"); // blah
assertThat(myComponent.toString()).isEqualTo("SingletonComponent"); // better

Annotate type and gender properties with @XmlAttribute and the description property with @XmlValue:

package org.example.sport;

import javax.xml.bind.annotation.*;

@XmlAccessorType(XmlAccessType.FIELD)
@XmlRootElement
public class Sport {

    @XmlAttribute
    protected String type;

    @XmlAttribute
    protected String gender;

    @XmlValue;
    protected String description;

}

When the JVM loads classes, or otherwise sees a literal string, or some code interns a string, it adds the string to a mostly-hidden lookup table that has one copy of each such string. If another copy is added, the runtime arranges it so that all the literals refer to the same string object. This is called "interning". If you say something like

String s = "test";
return (s == "test");

it'll return true, because the first and second "test" are actually the same object. Comparing interned strings this way can be much, much faster than String.equals, as there's a single reference comparison rather than a bunch of char comparisons.

You can add a string to the pool by calling String.intern(), which will give you back the pooled version of the string (which could be the same string you're interning, but you'd be crazy to rely on that -- you often can't be sure exactly what code has been loaded and run up til now and interned the same string). The pooled version (the string returned from intern) will be equal to any identical literal. For example:

String s1 = "test";
String s2 = new String("test");  // "new String" guarantees a different object

System.out.println(s1 == s2);  // should print "false"

s2 = s2.intern();
System.out.println(s1 == s2);  // should print "true"

In my case, the file (and the directory) that XCode was mentioning was incorrect, and the issue started occurring after a Git merge with a relatively huge branch. To fix the same, I did the following steps:

• Searched for the file in the directory system of XCode.
• Found the errored file highlighted in red (i.e, it was missing).
• Right clicked on the file and removed the file.
• I tried building my code again, and voila, it was successful.

I hope these steps help someone out.

I agree with guys. But sometimes you have to add more things.

IE

1) Add this worker.WorkerSupportsCancellation = true;

2) Add to you class some method to do the following things

public void KillMe()
{
   worker.CancelAsync();
   worker.Dispose();
   worker = null;
   GC.Collect();
}

So before close your application your have to call this method.

3) Probably you can Dispose, null all variables and timers which are inside of the BackgroundWorker.

I like using a package.json file in the root of your app folder.

Here is one I use

nvm use v0.6.4

http://pastie.org/3232212

npm install

This code may help you:

double d = double.Parse(input_value);
string output= d.ToString("F2", CultureInfo.InvariantCulture) + "%";

Most of the solutions here did not work for me so I used the one found here

I also added a variable to allow the confirm box or not

window.hideWarning = false;
window.addEventListener('beforeunload', (event) => {
    if (!hideWarning) {
        event.preventDefault();
        event.returnValue = '';
    }

});

You can also create a new jsp file sayng that form is submited and in your main action file just write its file name

Eg. Your form is submited is in a file succes.jsp Then your action file will have

Request.sendRedirect("success.jsp")

You have to change MySQL settings. Edit my.cnf file and put this setting in mysqld section:

[mysqld]
default_authentication_plugin= mysql_native_password

Then run following command:

FLUSH PRIVILEGES;

Above command will bring into effect the changes of default authentication mechanism.

I had the same issue trying to do something the same as you and I fixed it with something similar to Richie Fredicson's answer.

When you run createComponent() it is created with undefined input variables. Then after that when you assign data to those input variables it changes things and causes that error in your child template (in my case it was because I was using the input in an ngIf, which changed once I assigned the input data).

The only way I could find to avoid it in this specific case is to force change detection after you assign the data, however I didn't do it in ngAfterContentChecked().

Your example code is a bit hard to follow but if my solution works for you it would be something like this (in the parent component):

export class ParentComponent implements AfterViewInit {
  // I'm assuming you have a WidgetDirective.
  @ViewChild(WidgetDirective) widgetHost: WidgetDirective;

  constructor(
    private componentFactoryResolver: ComponentFactoryResolver,
    private changeDetector: ChangeDetectorRef
  ) {}

  ngAfterViewInit() {
    renderWidgetInsideWidgetContainer();
  }

  renderWidgetInsideWidgetContainer() {
    let component = this.storeFactory.getWidgetComponent(this.dataSource.ComponentName);
    let componentFactory = this.componentFactoryResolver.resolveComponentFactory(component);
    let viewContainerRef = this.widgetHost.viewContainerRef;
    viewContainerRef.clear();
    let componentRef = viewContainerRef.createComponent(componentFactory);
    debugger;
    // This <IDataBind> type you are using here needs to be changed to be the component
    // type you used for the call to resolveComponentFactory() above (if it isn't already).
    // It tells it that this component instance if of that type and then it knows
    // that WidgetDataContext and WidgetPosition are @Inputs for it.
    (<IDataBind>componentRef.instance).WidgetDataContext = this.dataSource.DataContext;
    (<IDataBind>componentRef.instance).WidgetPosition = this.dataSource.Position;
    this.changeDetector.detectChanges();
  }
}

Mine is almost the same as that except I'm using @ViewChildren instead of @ViewChild as I have multiple host elements.

Also, if you'd like to know global memory rather than node process':

var os = require('os');

os.freemem();
os.totalmem();

See documentation

In .NET 4 you don't need the ToArray() call - string.Join is overloaded to accept IEnumerable<T> or just IEnumerable<string>.

There are potentially more efficient ways of doing it before .NET 4, but do you really need them? Is this actually a bottleneck in your code?

You could iterate over the list, work out the final size, allocate a StringBuilder of exactly the right size, then do the join yourself. That would avoid the extra array being built for little reason - but it wouldn't save much time and it would be a lot more code.

I don't know why, but for some reason, the "/bin/bash" version didn't work for me. Instead, the simpler version worked, following the example given here at Oracle Docs.

String[] args = new String[] {"ping", "www.google.com"};
Process proc = new ProcessBuilder(args).start();

Actually "Sheet1" object / code name can be changed. In VBA, click on Sheet1 in Excel Objects list. In the properties window, you can change Sheet1 to say rng.

Then you can reference rng as a global object without having to create a variable first. So debug.print rng.name works just fine. No more Worksheets("rng").name.

Unlike the tab, the object name has same restrictions as other variables (i.e. no spaces).

You can use relative rules:

table td + td + td + td + td {
  border: none;
}

This only works if the number of columns isn't determined at runtime.

Try this approach:

SELECT TOP @offset a.*
FROM (select top @limit b.*, COUNT(*) OVER() totalrows 
        from TABLENAME b order by id asc) a
ORDER BY id desc;

You can use something like this:
HTML:

<div><input class="yourClass" type="checkbox" value="1" checked></div>
<div><input class="yourClass" type="checkbox" value="2"></div>
<div><input class="yourClass" type="checkbox" value="3" checked></div>
<div><input class="yourClass" type="checkbox" value="4"></div>

JQuery:

$(".yourClass:checkbox").filter(":checked")

It will choose values of 1 and 3.

int is a primitive type, you can read what does mean a primitive type in java here, and a Map is an interface that has to objects as input:

public interface Map<K extends Object, V extends Object>

object means a class, and it means also that you can create an other class that exends from it, but you can not create a class that exends from int. So you can not use int variable as an object. I have tow solutions for your problem:

Map<String, Integer> map = new HashMap<>();

or

Map<String, int[]> map = new HashMap<>();
int x = 1;

//put x in map
int[] x_ = new int[]{x};
map.put("x", x_);

//get the value of x
int y = map.get("x")[0];

Try adding these after <Playlist>

<AutoLoad>false</AutoLoad>
<AutoPlay>false</AutoPlay>

Your syntax is not correct. It should be like that:

for (Tweet tweet : tweets) {              
    for(long forId : idFromArray){
        long tweetId = tweet.getId();
        if(forId != tweetId){
            String twitterString = tweet.getText();
            db.insertTwitter(twitterString);
        }
    }
}

This answer no longer really answers the question since it was updated ;)

string s = (string)o; // 1

Throws InvalidCastException if o is not a string. Otherwise, assigns o to s, even if o is null.

string s = o as string; // 2

Assigns null to s if o is not a string or if o is null. For this reason, you cannot use it with value types (the operator could never return null in that case). Otherwise, assigns o to s.

string s = o.ToString(); // 3

Causes a NullReferenceException if o is null. Assigns whatever o.ToString() returns to s, no matter what type o is.

Use 1 for most conversions - it's simple and straightforward. I tend to almost never use 2 since if something is not the right type, I usually expect an exception to occur. I have only seen a need for this return-null type of functionality with badly designed libraries which use error codes (e.g. return null = error, instead of using exceptions).

3 is not a cast and is just a method invocation. Use it for when you need the string representation of a non-string object.

In swift 3

let nextVC = self.storyboard?.instantiateViewController(withIdentifier: "NextViewController") as! NextViewController        
self.navigationController?.pushViewController(nextVC, animated: true)

You can use contains (this works with an arbitrary sequence):

df.filter($"foo".contains("bar"))

like (SQL like with SQL simple regular expression whith _ matching an arbitrary character and % matching an arbitrary sequence):

df.filter($"foo".like("bar"))

or rlike (like with Java regular expressions):

df.filter($"foo".rlike("bar"))

depending on your requirements. LIKE and RLIKE should work with SQL expressions as well.

Less no longer evaluates expression inside calc by default since v3.00.

Original answer (Less v1.x...2.x):

Do this:

body { width: calc(~"100% - 250px - 1.5em"); }

In Less 1.4.0 we will have a strictMaths option which requires all Less calculations to be within brackets, so the calc will work "out-of-the-box". This is an option since it is a major breaking change. Early betas of 1.4.0 had this option on by default. The release version has it off by default.

Here's a way that I consider easier: The general idea is that you want to append a text element to a circle element then play around with its "dx" and "dy" attributes until you position the text at the point in the circle that you like. In my example, I used a negative number for the dx since I wanted to have text start towards the left of the centre.

const nodes = [ {id: ABC, group: 1, level: 1}, {id:XYZ, group: 2, level: 1}, ]

const nodeElems = svg.append('g')
.selectAll('circle')
.data(nodes)
.enter().append('circle')
.attr('r',radius)
.attr('fill', getNodeColor)

const textElems = svg.append('g')
.selectAll('text')
.data(nodes)
.enter().append('text')
.text(node => node.label)
.attr('font-size',8)//font size
.attr('dx', -10)//positions text towards the left of the center of the circle
.attr('dy',4)

Note that this OP Question appeared not to be about port numbers afterall. If you are using the default port of 3306 always, then consider removing it from the uri, that is, remove the port=$port; part.

If you often change ports, consider the above port usage for more maintainability having changes made to the $port variable.

Some likely errors returned from above:

PDO Exception: SQLSTATE[HY000] [2002] No connection could be made because the target machine actively refused it.
PDO Exception: SQLSTATE[HY000] [2002] php_network_getaddresses: getaddrinfo failed: No such host is known.

In the below error, we are at least getting closer, after changing our connect information:

PDO Exception: SQLSTATE[HY000] [1045] Access denied for user 'GuySmiley'@'localhost' (using password: YES)

After further changes, we are really close now, but not quite:

PDO Exception: SQLSTATE[HY000] [1049] Unknown database 'mustard'

From the Manual on PDO Connections:

It's also used in regular expressions, meaning "at most one repetition of the preceding character"

for example the regular expression /hey?/ matches with the strings "he" and "hey".

It supports lists, but not as a separate data structure (ignoring arrays for the moment).

The for loop iterates over a list (in the generic sense) of white-space separated values, regardless of how that list is created, whether literally:

for i in 1 2 3; do
    echo "$i"
done

or via parameter expansion:

listVar="1 2 3"
for i in $listVar; do
    echo "$i"
done

or command substitution:

for i in $(echo 1; echo 2; echo 3); do
    echo "$i"
done

An array is just a special parameter which can contain a more structured list of value, where each element can itself contain whitespace. Compare the difference:

array=("item 1" "item 2" "item 3")
for i in "${array[@]}"; do   # The quotes are necessary here
    echo "$i"
done

list='"item 1" "item 2" "item 3"'
for i in $list; do
    echo $i
done
for i in "$list"; do
    echo $i
done
for i in ${array[@]}; do
    echo $i
done

I use this code to remove my data but leave the formulas in the top row. It also removes all rows except for the top row and scrolls the page up to the top.

Sub CleanTheTable()
    Application.ScreenUpdating = False
    Sheets("Data").Select
    ActiveSheet.ListObjects("TestTable").HeaderRowRange.Select
    'Remove the filters if one exists.
    If ActiveSheet.FilterMode Then
    Selection.AutoFilter
    End If
    'Clear all lines but the first one in the table leaving formulas for the next go round.
    With Worksheets("Data").ListObjects("TestTable")
    .Range.AutoFilter
    On Error Resume Next
    .DataBodyRange.Offset(1).Resize(.DataBodyRange.Rows.Count - 1, .DataBodyRange.Columns.Count).Rows.Delete
    .DataBodyRange.Rows(1).SpecialCells(xlCellTypeConstants).ClearContents
    ActiveWindow.SmallScroll Down:=-10000

Application.ScreenUpdating = True

Try LIKE construction, e.g. (assuming StudentId is of type Char, VarChar etc.)

Do a readline at the end (it's the "forma cochina", like we say in Colombia, but it works):

}

Instead of

CGContextDrawImage(context, CGRectMake(0, 0, 145, 15), image.CGImage);

Use

[image drawInRect:CGRectMake(0, 0, 145, 15)];

In the middle of your begin/end CGcontext methods.

This will draw the image with the correct orientation into your current image context - I'm pretty sure this has something to do with the UIImage holding onto knowledge of the orientation while the CGContextDrawImage method gets the underlying raw image data with no understanding of orientation.

The Adjusted R-squared is close to, but different from, the value of R2. Instead of being based on the explained sum of squares SSR and the total sum of squares SSY, it is based on the overall variance (a quantity we do not typically calculate), s2T = SSY/(n - 1) and the error variance MSE (from the ANOVA table) and is worked out like this: adjusted R-squared = (s2T - MSE) / s2T.

This approach provides a better basis for judging the improvement in a fit due to adding an explanatory variable, but it does not have the simple summarizing interpretation that R2 has.

If I haven't made a mistake, you should verify the values of adjusted R-squared and R-squared as follows:

s2T <- sum(anova(v.lm)[[2]]) / sum(anova(v.lm)[[1]])
MSE <- anova(v.lm)[[3]][2]
adj.R2 <- (s2T - MSE) / s2T

On the other side, R2 is: SSR/SSY, where SSR = SSY - SSE

attach(v)
SSE <- deviance(v.lm) # or SSE <- sum((epm - predict(v.lm,list(n_days)))^2)
SSY <- deviance(lm(epm ~ 1)) # or SSY <- sum((epm-mean(epm))^2)
SSR <- (SSY - SSE) # or SSR <- sum((predict(v.lm,list(n_days)) - mean(epm))^2)
R2 <- SSR / SSY 

Update or Delete with sql transaction

 private void SQLTransaction() {
   try {
     string sConnectionString = "My Connection String";
     string query = "UPDATE [dbo].[MyTable] SET ColumnName = '{0}' WHERE ID = {1}";

     SqlConnection connection = new SqlConnection(sConnectionString);
     SqlCommand command = connection.CreateCommand();
     connection.Open();
     SqlTransaction transaction = connection.BeginTransaction("");
     command.Transaction = transaction;
     try {
       foreach(DataRow row in dt_MyData.Rows) {
         command.CommandText = string.Format(query, row["ColumnName"].ToString(), row["ID"].ToString());
         command.ExecuteNonQuery();
       }
       transaction.Commit();
     } catch (Exception ex) {
       transaction.Rollback();
       MessageBox.Show(ex.Message, "Error");
     }
   } catch (Exception ex) {
     MessageBox.Show("Problem connect to database.", "Error");
   }
 }

Here’s the JavaScript equivalent:

var i = null;
var j = i || 10; //j is now 10

Note that the logical operator || does not return a boolean value but the first value that can be converted to true.

Additionally use an array of objects instead of one single object:

var options = {
    filters: [
        {
            name: 'firstName',
            value: 'abc'
        }
    ]
};
var filter  = options.filters[0] || '';  // is {name:'firstName', value:'abc'}
var filter2 = options.filters[1] || '';  // is ''

That can be accessed by index.

Putting the call to mysql_insert_id() inside a transaction, should do it:

mysql_query('BEGIN');
// Whatever code that does the insert here.
$id = mysql_insert_id();
mysql_query('COMMIT');
// Stuff with $id.

You can get free Virtual Machine and many more things online for 3 months provided by Microsoft Azure. I guess you need VPN for learning purpose. For that it would suffice.

The best way I've found is to use a combination "IF" and "ISERROR" statement:

=IF(ISERROR(COUNTIF(E5:E356,1)),"---",COUNTIF(E5:E356,1)

This formula will either fill the cell with three dashes (---) if there would be an error (if there is no data in the cells to count/average/etc), or with the count (if there was data in the cells)

The nice part about this logical query is that it will exclude entirely blank rows/columns by making them textual values of "---", so if you have a row counting (or averaging), which was then counted (or averaged) in another spot in your formula, the second formula won't respond with an error because it will ignore the "---" cell.

AngularJs Code-sample

var app = angular.module('urlApp', []);
app.controller('urlCtrl', function ($scope, $log, $window) {
    $scope.ClickMeToRedirect = function () {
        var url = "http://" + $window.location.host + "/Account/Login";
        $log.log(url);
        $window.location.href = url;
    };
});

HTML Code-sample

<div ng-app="urlApp">
    <div ng-controller="urlCtrl">
        Redirect to <a href="#" ng-click="ClickMeToRedirect()">Click Me!</a>
    </div>
</div>

Check which module the parent component is being declared in...

If your parent component is defined in the shared module, so must your child module.

The parent component could be declared in a shared module and not the module that is logical based on the file directory structure / naming, even the Angular CLI added it into the wrong module in my case.

Your angular module needs to be initialized properly. The global object app needs to be defined and initialized correctly to inject the service.

Please see below sample code for reference:

app.js

var app = angular.module('SampleApp',['ngRoute']); //You can inject the dependencies within the square bracket    

app.config(['$routeProvider', '$locationProvider', function($routeProvider, $locationProvider) {
  $routeProvider
    .when('/', {
      templateUrl:"partials/login.html",
      controller:"login"
    });

  $locationProvider
    .html5Mode(true);
}]);

app.factory('getSettings', ['$http', '$q', function($http, $q) {
  return {
    //Code edited to create a function as when you require service it returns object by default so you can't return function directly. That's what understand...
    getSetting: function (type) { 
      var q = $q.defer();
      $http.get('models/settings.json').success(function (data) {
        q.resolve(function() {
          var settings = jQuery.parseJSON(data);
          return settings[type];
        });
      });
      return q.promise;
    }
  }
}]);

app.controller("globalControl", ['$scope','getSettings', function ($scope,getSettings) {
  //Modified the function call for updated service
  var loadSettings = getSettings.getSetting('global');
  loadSettings.then(function(val) {
    $scope.settings = val;
  });
}]);

Sample HTML code should be like this:

<!DOCTYPE html>
<html>
    <head lang="en">
        <title>Sample Application</title>
    </head>
    <body ng-app="SampleApp" ng-controller="globalControl">
        <div>
            Your UI elements go here
        </div>
        <script src="app.js"></script>
    </body>
</html>

Please note that the controller is not binding to an HTML tag but to the body tag. Also, please try to include your custom scripts at end of the HTML page as this is a standard practice to follow for performance reasons.

I hope this will solve your basic injection issue.

Since you state (in a clarification comment to another person's answer) that you are using MySQL Workbench, you could try using the "sql script" option there. This will avoid the need to use the commandline (although I agree with the other answer that it's good to climb up on that horse and learn to ride).

1. In MySQL Workbench, go to File menu, then select "open script". This is probably going to take a long time and might even crash the app since it's not made to open things that are as big as what you describe.

2. The better way is to use the commandline. Make sure you have MySQL client installed on your machine. This means the actual MySQL (not Workbench GUI or PhpMyAdmin or anything like that). Here is a link describing the command-line tool. Once you have that downloaded and installed, open a terminal window on your machine, and you have two choices for slurping data from your file system (such as in a backup file) up into your target database. One is to use 'source' command and the other is to use the < redirection operator.

Option 1: from the directory where your backup file is:

$mysql -u username -p -h hostname databasename < backupfile.sql

Option 2: from the directory where your backup file is:

$mysql -u username -p -h hostname
[enter your password]
> use databasename;
> source backupfile.sql

Obviously, both of these options require that you have a backup file that is SQL.

Another possible reason for this error for the Mega 2560 is if your code has three exclamation marks in a row. Perhaps in a recently added string.

3 bang marks in a row causes the Mega 2560 bootloader to go into Monitor mode from which it can not finish programming.

"!!!" <--- breaks Mega 2560 bootloader.

To fix, unplug the Arduino USB to reset the COM port and then recompile with only two exclamation points or with spaces between or whatever. Then reconnect the Arduino and program as usual.

Yes, this bit me yesterday and today I tracked down the culprit. Here is a link with more information: http://forum.arduino.cc/index.php?topic=132595.0

It's better to use $(window).scroll() rather than $('#Eframe').on("mousewheel")

$('#Eframe').on("mousewheel") will not trigger if people manually scroll using up and down arrows on the scroll bar or grabbing and dragging the scroll bar itself.

$(window).scroll(function(){
    var scrollPos = $(document).scrollTop();
    console.log(scrollPos);
});

If #Eframe is an element with overflow:scroll on it and you want it's scroll position. I think this should work (I haven't tested it though).

$('#Eframe').scroll(function(){
    var scrollPos = $('#Eframe').scrollTop();
    console.log(scrollPos);
});

It might mean the application is already installed for another user on your device. Users share applications. I don't know why they do but they do. So if one user updates an application is updated for the other user also. If you uninstall on one, it doesn't remove the app from the system on the other.

To redirect your logs output to a file, you need to use the FileAppender and need to define other file details in your log4j.properties/xml file. Here is a sample properties file for the same:

# Root logger option
log4j.rootLogger=INFO, file

# Direct log messages to a log file
log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.File=C:\\loging.log
log4j.appender.file.MaxFileSize=1MB
log4j.appender.file.MaxBackupIndex=1
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n

Follow this tutorial to learn more about log4j usage:

one thing I want to add , before you try to install

apt-get install php5-sqlite

or

apt-get install php5-sqlite3 

search the given package is available or not :-

 # apt-cache search 'php5'

After that you get :-

php5-rrd - rrd module for PHP 5

php5-sasl - Cyrus SASL extension for PHP 5

php5-snmp - SNMP module for php5

**php5-sqlite - SQLite module for php5**

php5-svn - PHP Bindings for the Subversion Revision control system

php5-sybase - Sybase / MS SQL Server module for php5

Here you get an idea about whether your version support or not .. in my system I get php5-sqlite - SQLite module for php5 so I prefer to install

**apt-get install php5-sqlite**

You can also try this:

import * as drawGauge from '../../../../js/d3gauge.js';

and just new drawGauge(this.opt); in your ts-code. This solution works in project with angular-cli embedded into laravel on which I currently working on. In my case I try to import poliglot library (btw: very good for translations) from node_modules:

import * as Polyglot from '../../../node_modules/node-polyglot/build/polyglot.min.js';
...
export class Lang 
{
    constructor() {

        this.polyglot = new Polyglot({ locale: 'en' });
        ...
    }
    ...
}

This solution is good because i don't need to COPY any files from node_modules :) .

UPDATE

You can also look on this LIST of ways how to include libs in angular.

#ifndef <token>
/* code */
#else
/* code to include if the token is defined */
#endif

#ifndef checks whether the given token has been #defined earlier in the file or in an included file; if not, it includes the code between it and the closing #else or, if no #else is present, #endif statement. #ifndef is often used to make header files idempotent by defining a token once the file has been included and checking that the token was not set at the top of that file.

#ifndef _INCL_GUARD
#define _INCL_GUARD
#endif

var request = URLRequest(url: URL(string: "http://yogpande.apphb.com/api/my/posttblhouse")!)
        request.httpMethod = "POST"
        let postString = "[email protected]&password=1234567"
        request.httpBody = postString.data(using: .utf8)
        let task = URLSession.shared.dataTask(with: request) { data, response, error in
            guard let data = data, error == nil else {
                print("error=(error)")
                return
            }

            if let httpStatus = response as? HTTPURLResponse, httpStatus.statusCode != 200 {     
                print("statusCode should be 200, but is \(httpStatus.statusCode)")
                print("response = \(response)")

            }

            let responseString = String(data: data, encoding: .utf8)
            print("responseString = \(responseString)")
        }
        task.resume()
    }

For those who want to use Python, here's a simple routine that removes parenthesized substrings, including those with nested parentheses. Okay, it's not a regex, but it'll do the job!

def remove_nested_parens(input_str):
    """Returns a copy of 'input_str' with any parenthesized text removed. Nested parentheses are handled."""
    result = ''
    paren_level = 0
    for ch in input_str:
        if ch == '(':
            paren_level += 1
        elif (ch == ')') and paren_level:
            paren_level -= 1
        elif not paren_level:
            result += ch
    return result

remove_nested_parens('example_(extra(qualifier)_text)_test(more_parens).ext')

Use the ampersand just like you would from the shell.

#!/usr/bin/bash
function_to_fork() {
   ...
}

function_to_fork &
# ... execution continues in parent process ...

Yes its possible to pass JSON object in URL

queryString = "{\"left\":\"" + params.get("left") + "}";
 httpRestTemplate.exchange(
                    Endpoint + "/A/B?query={queryString}",
                    HttpMethod.GET, entity, z.class, queryString);

Had this issue with a true HTTPS binding and the same exception with "This could be due to the fact that the server certificate is not configured properly with HTTP.SYS in the HTTPS case...". After double checking everything in code and config, it seems like the error message is not so misleading as the inner exceptions, so after a quick check we've found out that the port 443 was hooked by skype (on the dev server). I recommend you take a look at what holding up the request (Fiddler could help here) and make sure you can reach the service front (view the .svc in your browser) and its metadata.

Good luck.

Another approach is to use ForEach-Object to project individual items to a string and then use the Out-String CmdLet to project the final results to a string or string array:

gci Microsoft.PowerShell.Core\Registry::HKEY_CLASSES_ROOT\CID | foreach { "CID Key {0}" -f $_.Name } | Out-String

#Result: One multi-line string equal to:
@"
CID Key HKEY_CLASSES_ROOT\CID\2a621c8a-7d4b-4d7b-ad60-a957fd70b0d0
CID Key HKEY_CLASSES_ROOT\CID\2ec6f5b2-8cdc-461e-9157-ffa84c11ba7d
CID Key HKEY_CLASSES_ROOT\CID\5da2ceaf-bc35-46e0-aabd-bd826023359b
CID Key HKEY_CLASSES_ROOT\CID\d13ad82e-d4fb-495f-9b78-01d2946e6426
"@

gci Microsoft.PowerShell.Core\Registry::HKEY_CLASSES_ROOT\CID | foreach { "CID Key {0}" -f $_.Name } | Out-String -Stream

#Result: An array of single line strings equal to:
@(
"CID Key HKEY_CLASSES_ROOT\CID\2a621c8a-7d4b-4d7b-ad60-a957fd70b0d0",
"CID Key HKEY_CLASSES_ROOT\CID\2ec6f5b2-8cdc-461e-9157-ffa84c11ba7d",
"CID Key HKEY_CLASSES_ROOT\CID\5da2ceaf-bc35-46e0-aabd-bd826023359b",
"CID Key HKEY_CLASSES_ROOT\CID\d13ad82e-d4fb-495f-9b78-01d2946e6426")

The benefit of this approach is that you can store the result to a variable and it will NOT have any empty lines.

Create a SQLCLR assembly with external access permission that returns the list of files as a result set. There are many examples how to do this, eg. Yet another TVF: returning files from a directory or Trading in xp_cmdshell for SQLCLR (Part 1) - List Directory Contents.

You get this error if you have constrained T to being a class

Simple one-liner that always works, given that you are currently on the branch you want to squash, master is the branch it originated from, and the latest commit contains the commit message and author you wish to use:

git reset --soft $(git merge-base HEAD master) && git commit --reuse-message=HEAD@{1}

Change Host for a Git Origin Server

from: http://pseudofish.com/blog/2010/06/28/change-host-for-a-git-origin-server/

Hopefully this isn’t something you need to do. The server that I’ve been using to collaborate on a few git projects with had the domain name expire. This meant finding a way of migrating the local repositories to get back in sync.

Update: Thanks to @mawolf for pointing out there is an easy way with recent git versions (post Feb, 2010):

git remote set-url origin ssh://newhost.com/usr/local/gitroot/myproject.git

See the man page for details.

If you’re on an older version, then try this:

As a caveat, this works only as it is the same server, just with different names.

Assuming that the new hostname is newhost.com, and the old one was oldhost.com, the change is quite simple.

Edit the .git/config file in your working directory. You should see something like:

[remote "origin"]
fetch = +refs/heads/*:refs/remotes/origin/*
url = ssh://oldhost.com/usr/local/gitroot/myproject.git

Change oldhost.com to newhost.com, save the file and you’re done.

From my limited testing (git pull origin; git push origin; gitx) everything seems in order. And yes, I know it is bad form to mess with git internals.

The answer is wrong, it only works when the file does not exist. If the file exists, using the first does nothing, the second adds a line at the end of the file.

The correct answer is:

copy /b filename.ext +,,

I found it here: https://superuser.com/questions/10426/windows-equivalent-of-the-linux-command-touch/764721#764721

Make sure git-upload-pack is on the path from a non-login shell. (On my machine it's in /usr/bin).

To see what your path looks like on the remote machine from a non-login shell, try this:

ssh you@remotemachine echo \$PATH

(That works in Bash, Zsh, and tcsh, and probably other shells too.)

If the path it gives back doesn't include the directory that has git-upload-pack, you need to fix it by setting it in .bashrc (for Bash), .zshenv (for Zsh), .cshrc (for tcsh) or equivalent for your shell.

You will need to make this change on the remote machine.

If you're not sure which path you need to add to your remote PATH, you can find it with this command (you need to run this on the remote machine):

which git-upload-pack

On my machine that prints /usr/bin/git-upload-pack. So in this case, /usr/bin is the path you need to make sure is in your remote non-login shell PATH.

here is a useful gist from lfmingo

OkHttpClient.Builder httpClient = new OkHttpClient.Builder();

httpClient.addInterceptor(new Interceptor() {

    @Override
    public Response intercept(Interceptor.Chain chain) throws IOException {
        Request original = chain.request();

            .header("User-Agent", "Your-App-Name")
            .header("Accept", "application/vnd.yourapi.v1.full+json")
            .method(original.method(), original.body())
            .build();

        return chain.proceed(request);

Retrofit retrofit = new Retrofit.Builder()  
    .baseUrl(API_BASE_URL)
    .addConverterFactory(GsonConverterFactory.create())
    .client(client)

I find the solution in spring.io,like this:

    response.setHeader("Access-Control-Allow-Origin", "*");
    response.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE");

On the etymology the term boilerplate: from http://www.takeourword.com/Issue009.html...

Interestingly, the term arose from the newspaper business. Columns and other pieces that were syndicated were sent out to subscribing newspapers in the form of a mat (i.e. a matrix). Once received, boiling lead was poured into this mat to create the plate used to print the piece, hence the name boilerplate. As the article printed on a boilerplate could not be altered, the term came to be used by attorneys to refer to the portions of a contract which did not change through repeated uses in different applications, and finally to language in general which did not change in any document that was used repeatedly for different occasions.

What constitutes boilerplate in programming? As may others have pointed out, it is just a chunk of code that is copied over and over again with little or no changes made to it in the process.

To get all divs under 'container', use the following:

$(".container>div")  //or
$(".container").children("div");

You can stipulate a specific #id instead of div to get a particular one.

You say you want a div with an 'undefined' id. if I understand you right, the following would achieve this:

$(".container>div[id=]")

Very easy step by step (100% working and tested)

step1: Create method on first view controller

 func updateProcessStatus(isCompleted : Bool){
    if isCompleted{
        self.labelStatus.text = "Process is completed"
    }else{
        self.labelStatus.text = "Process is in progress"
    }
}

step2: Set delegate while push to second view controller

@IBAction func buttonAction(_ sender: Any) {

    let secondViewController = self.storyboard?.instantiateViewController(withIdentifier: "secondViewController") as! secondViewController
    secondViewController.delegate = self
    self.navigationController?.pushViewController(secondViewController, animated: true)
}

step3: set delegate like

class ViewController: UIViewController,ProcessStatusDelegate {

step4: Create protocol

protocol ProcessStatusDelegate:NSObjectProtocol{
func updateProcessStatus(isCompleted : Bool)
}

step5: take a variable

var delegate:ProcessStatusDelegate?

step6: While go back to previous view controller call delegate method so first view controller notify with data

@IBAction func buttonActionBack(_ sender: Any) {
    delegate?.updateProcessStatus(isCompleted: true)
    self.navigationController?.popViewController(animated: true)
}

@IBAction func buttonProgress(_ sender: Any) {
    delegate?.updateProcessStatus(isCompleted: false)
    self.navigationController?.popViewController(animated: true)

}

In Sybase SQL Anywhere, the columns and table information are stored separately, so you need a join:

select c.column_name from systabcol c 
       key join systab t on t.table_id=c.table_id 
       where t.table_name='tablename'

If I start with a 3x4 array, and concatenate a 3x1 array, with axis 1, I get a 3x5 array:

In [911]: x = np.arange(12).reshape(3,4)
In [912]: np.concatenate([x,x[:,-1:]], axis=1)
Out[912]: 
array([[ 0,  1,  2,  3,  3],
       [ 4,  5,  6,  7,  7],
       [ 8,  9, 10, 11, 11]])
In [913]: x.shape,x[:,-1:].shape
Out[913]: ((3, 4), (3, 1))

Note that both inputs to concatenate have 2 dimensions.

Omit the :, and x[:,-1] is (3,) shape - it is 1d, and hence the error:

In [914]: np.concatenate([x,x[:,-1]], axis=1)
...
ValueError: all the input arrays must have same number of dimensions

The code for np.append is (in this case where axis is specified)

return concatenate((arr, values), axis=axis)

So with a slight change of syntax append works. Instead of a list it takes 2 arguments. It imitates the list append is syntax, but should not be confused with that list method.

In [916]: np.append(x, x[:,-1:], axis=1)
Out[916]: 
array([[ 0,  1,  2,  3,  3],
       [ 4,  5,  6,  7,  7],
       [ 8,  9, 10, 11, 11]])

np.hstack first makes sure all inputs are atleast_1d, and then does concatenate:

return np.concatenate([np.atleast_1d(a) for a in arrs], 1)

So it requires the same x[:,-1:] input. Essentially the same action.

np.column_stack also does a concatenate on axis 1. But first it passes 1d inputs through

array(arr, copy=False, subok=True, ndmin=2).T

This is a general way of turning that (3,) array into a (3,1) array.

In [922]: np.array(x[:,-1], copy=False, subok=True, ndmin=2).T
Out[922]: 
array([[ 3],
       [ 7],
       [11]])
In [923]: np.column_stack([x,x[:,-1]])
Out[923]: 
array([[ 0,  1,  2,  3,  3],
       [ 4,  5,  6,  7,  7],
       [ 8,  9, 10, 11, 11]])

All these 'stacks' can be convenient, but in the long run, it's important to understand dimensions and the base np.concatenate. Also know how to look up the code for functions like this. I use the ipython ?? magic a lot.

And in time tests, the np.concatenate is noticeably faster - with a small array like this the extra layers of function calls makes a big time difference.

The easiest way is to redirect the output of the echo by >>:

echo 'VNCSERVERS="1:root"' >> /etc/sysconfig/configfile
echo 'VNCSERVERARGS[1]="-geometry 1600x1200"' >> /etc/sysconfig/configfile

My approach is similar to what bpedit shows above, but with an iOS 9+ focus. I wanted to change the scope of the FSCalendar when the view rotates.

override func viewWillTransitionToSize(size: CGSize, withTransitionCoordinator coordinator: UIViewControllerTransitionCoordinator) {
    super.viewWillTransitionToSize(size, withTransitionCoordinator: coordinator)

    coordinator.animateAlongsideTransition({ (context) in
        if size.height < size.width {
            self.calendar.setScope(.Week, animated: true)
            self.calendar.appearance.cellShape = .Rectangle
        }
        else {
            self.calendar.appearance.cellShape = .Circle
            self.calendar.setScope(.Month, animated: true)

        }

        }, completion: nil)
}

This below worked, but I felt sheepish about it :)

coordinator.animateAlongsideTransition({ (context) in
        if size.height < size.width {
            self.calendar.scope = .Week
            self.calendar.appearance.cellShape = .Rectangle
        }
        }) { (context) in
            if size.height > size.width {
                self.calendar.scope = .Month
                self.calendar.appearance.cellShape = .Circle
            }
    }

One of the big uses for function pointers in C is to call a function selected at run-time. For example, the C run-time library has two routines, qsort and bsearch, which take a pointer to a function that is called to compare two items being sorted; this allows you to sort or search, respectively, anything, based on any criteria you wish to use.

A very basic example, if there is one function called print(int x, int y) which in turn may require to call a function (either add() or sub(), which are of the same type) then what we will do, we will add one function pointer argument to the print() function as shown below:

#include <stdio.h>

int add()
{
   return (100+10);
}

int sub()
{
   return (100-10);
}

void print(int x, int y, int (*func)())
{
    printf("value is: %d\n", (x+y+(*func)()));
}

int main()
{
    int x=100, y=200;
    print(x,y,add);
    print(x,y,sub);

    return 0;
}

The output is:

value is: 410
value is: 390

I use the following Ruby script to delete my already merged local and remote branches. If I'm doing it for a repository with multiple remotes and only want to delete from one, I just add a select statement to the remotes list to only get the remotes I want.

#!/usr/bin/env ruby

current_branch = `git symbolic-ref --short HEAD`.chomp
if current_branch != "master"
  if $?.exitstatus == 0
    puts "WARNING: You are on branch #{current_branch}, NOT master."
  else
    puts "WARNING: You are not on a branch"
  end
  puts
end

puts "Fetching merged branches..."
remote_branches= `git branch -r --merged`.
  split("\n").
  map(&:strip).
  reject {|b| b =~ /\/(#{current_branch}|master)/}

local_branches= `git branch --merged`.
  gsub(/^\* /, '').
  split("\n").
  map(&:strip).
  reject {|b| b =~ /(#{current_branch}|master)/}

if remote_branches.empty? && local_branches.empty?
  puts "No existing branches have been merged into #{current_branch}."
else
  puts "This will remove the following branches:"
  puts remote_branches.join("\n")
  puts local_branches.join("\n")
  puts "Proceed?"
  if gets =~ /^y/i
    remote_branches.each do |b|
      remote, branch = b.split(/\//)
      `git push #{remote} :#{branch}`
    end

    # Remove local branches
    `git branch -d #{local_branches.join(' ')}`
  else
    puts "No branches removed."
  end
end

$_FILES["file"]["name"] - the name of the uploaded file

You can use the asList method with varargs to do this in one line:

java.util.Arrays.asList('+', '-', '*', '^');

If the list does not need to be modified further then this would already be enough. Otherwise you can pass it to the ArrayList constructor to create a mutable list:

new ArrayList(Arrays.asList('+', '-', '*', '^'));

You can add the two strings separately in the builder, one of them is spannedString, the other is a regular one.This way you don`t have to calculate the indexes.

val instructionPress = resources?.getString(R.string.settings_press)

val okText = resources?.getString(R.string.ok)
val spannableString = SpannableString(okText)

val spannableBuilder = SpannableStringBuilder()
spannableBuilder.append(instructionPress)
spannableBuilder.append(spannableString, StyleSpan(Typeface.BOLD), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE)

instructionText.setText(spannableBuilder,TextView.BufferType.SPANNABLE)

What about:

SELECT COUNT(*) FROM (SELECT ID FROM Movies GROUP BY ID HAVING COUNT(Genre)=4) a

I think the other answers miss one important detail regarding the property name to use in the EL expression. The rules for converting from the method names to property names are specified in 'Introspector.decpitalize` which is part of the java bean standard:

This normally means converting the first character from upper case to lower case, but in the (unusual) special case when there is more than one character and both the first and second characters are upper case, we leave it alone.

Thus "FooBah" becomes "fooBah" and "X" becomes "x", but "URL" stays as "URL".

So in your case the JSTL code should look like the following, note the capital 'P':

<c:if test = "${ansokanInfo.PSystem == 'NAT'}">

The best solution we found was to team up with one of those intermediaries. Otherwise you will have to deal with a bunch of other requirements like PCI compliance. We use Verifone's IPCharge and it works quite well.

Table names cannot be supplied as parameters, so you'll have to construct the SQL string manually like this:

SET @SQLQuery = 'SELECT * FROM ' + @TableName + ' WHERE EmployeeID = @EmpID' 

However, make sure that your application does not allow a user to directly enter the value of @TableName, as this would make your query susceptible to SQL injection. For one possible solution to this, see this answer.

Log.v("blah", "blah blah");

You need to add the android Log view in eclipse to see them. There are also other methods depending on the severity of the message (error, verbose, warning, etc..).

For those coming later, in addition to the accepted answer that includes HAL, JSend, and JSON API, I would add a few other specifications worth looking into:

• JSON-LD, which is a W3C Recommendation and specifies how to build interoperable Web Services in JSON
• Ion Hypermedia Type for REST, which claims itself as a "a simple and intuitive JSON-based hypermedia type for REST"

use document.write for example,

<script>
  document.write(' <?php add(1,2); ?> ');
  document.write(' <?php milt(1,2); ?> ');
  document.write(' <?php divide(1,2); ?> ');
</script>

SELECT e1.empno EmployeeId, e1.ename EmployeeName, 
       e1.mgr ManagerId, e2.ename AS ManagerName
FROM   emp e1, emp e2
       where e1.mgr = e2.empno
