I think you could try this too:

const currentEnv = process.env;
process.env = { ENV_NODE: 'whatever' };

// test code...

process.env = currentEnv;

This works for me and you don't need module things

Suppose you bound your combobox to a List<Person>

List<Person> pp = new List<Person>();
pp.Add(new Person() {id = 1, name="Steve"});
pp.Add(new Person() {id = 2, name="Mark"});
pp.Add(new Person() {id = 3, name="Charles"});

cbo1.DisplayMember = "name";
cbo1.ValueMember = "id";
cbo1.DataSource = pp;

At this point you cannot set the Text property as you like, but instead you need to add an item to your list before setting the datasource

pp.Insert(0, new Person() {id=-1, name="--SELECT--"});
cbo1.DisplayMember = "name";
cbo1.ValueMember = "id";
cbo1.DataSource = pp;
cbo1.SelectedIndex = 0;

Of course this means that you need to add a checking code when you try to use the info from the combobox

if(cbo1.SelectedValue != null && Convert.ToInt32(cbo1.SelectedValue) == -1)
    MessageBox.Show("Please select a person name");
else
    ...... 

The code is the same if you use a DataTable instead of a list. You need to add a fake row at the first position of the Rows collection of the datatable and set the initial index of the combobox to make things clear. The only thing you need to look at are the name of the datatable columns and which columns should contain a non null value before adding the row to the collection

In a table with three columns like ID, FirstName, LastName with ID,FirstName and LastName required you need to

DataRow row = datatable.NewRow();
row["ID"] = -1;
row["FirstName"] = "--Select--";    
row["LastName"] = "FakeAddress";
dataTable.Rows.InsertAt(row, 0);

You can run the sleep command before your ExecStart with ExecStartPre :

[Service]
ExecStartPre=/bin/sleep 30

I had been suffering from a similar issue. I was trying to import my config file to my container so that I can fix it every time I need without re-building the image.

I mean I thought the below command would map $(pwd)/config.py from Docker host to /root/app/config.py into the container as a file.

docker run -v $(pwd)/config.py:/root/app/config.py my_docker_image

However, it always created a directory named config.py, not a file.

while looking for clue, I found the reason(from here)

If you use -v or --volume to bind-mount a file or directory that does not yet exist on the Docker host, -v will create the endpoint for you. It is always created as a directory.

Therefore, it is always created as a directory because my docker host does not have $(pwd)/config.py.

Even if I create config.py in docker host. $(pwd)/config.py just overwirte /root/app/config.py not exporting /root/app/config.py.

Her you go two solutions!

1. Modify ChangeDetectionStrategy to OnPush

For this solution, you'r basically telling angular:

Stop checking for changes; i'll do it only when i know is necessary

The quick fix:

Modify your component so it'll use ChangeDetectionStrategy.OnPush

@Component({
  selector: 'app-child',
  templateUrl: './child.component.html',
  changeDetection: ChangeDetectionStrategy.OnPush
})
export class ChildComponent implements OnInit {
    // ...
}

With this, things don’t seem to work anymore. That's because from now on you'll have to make Angular call the detectChanges() manually.

this.cdr.detectChanges();

Here's a link that helped me understand ChangeDetectionStrategy right: https://alligator.io/angular/change-detection-strategy/

2. Understanding ExpressionChangedAfterItHasBeenCheckedError

Here is a small extract from tomonari_t answer about the causes for this error, I've tried to include only the parts that helped me to understand this.

The full article shows real code examples about every point shown here.

The root cause is angular lifecycle's:

After each operation Angular remembers what values it used to perform an operation. They are stored in the oldValues property of the component view.

After the checks have been done for all components Angular then starts the next digest cycle but instead of performing operations it compares the current values with the ones it remembers from the previous digest cycle.

The following operations are the being checked at digest cycle's:

check that values passed down to the child components are the same as the values that would be used to update properties of these components now.

check that values used to update the DOM elements are the same as the values that would be used to update these elements now perform the same.

checks for all child components

And so, the error is thrown when the compared values are different., blogger Max Koretskyi stated:

The culprit is always the child component or a directive.

And finally here are some real world samples that usually cause this error:

• Shared services
• Synchronous event broadcasting
• Dynamic component instantiation

Every sample can be found here (plunkr), in my case the problem was a dynamic component instantiation.

Also, by my own experience i strongly recommend everyone to avoid the setTimeout solution, in my case caused an "almost" infinite loop (21 calls which i'm not willing to show you how to provoke them),

I would recommend to always keep in mind Angular life-cycle's so you can take in account how they would be affected every time you modify another component's value. With this error Angular is telling you:

You're maybe doing this the wrong way, are you sure you're right?

The same blog also says:

Often, the fix is to use the right change detection hook to create a dynamic component

A short guide for me is to consider at least the following two things while coding (i'll try to complement it over time):

1. Avoid modifying parent component values from it's child's components, instead: modify them from its parent.
2. When you use @Input and @Output directives try to avoid triggering lyfecycle changes unless the component is completely initialized.
3. Avoid unnecessary calls of this.cdr.detectChanges(); they can trigger more errors, specially when you'r dealing with a lot of dynamic data
4. When the use of this.cdr.detectChanges(); is mandatory make sure that the variables (@Input, @Output, etc) being used are filled/initialized at right detection hook (OnInit, OnChanges, AfterView, etc)
5. When possible, remove rather than hide, this is related to point 3 and 4.

Also

If you want to fully understand Angular Life Hook i recommend you to read the official documentation here:

• https://angular.io/guide/lifecycle-hooks

Note that I don't recommend a fixed IP for containers in Docker unless you're doing something that allows routing from outside to the inside of your container network (e.g. macvlan). DNS is already there for service discovery inside of the container network and supports container scaling. And outside the container network, you should use exposed ports on the host. With that disclaimer, here's the compose file you want:

version: '2'

services:
  mysql:
    container_name: mysql
    image: mysql:latest
    restart: always
    environment:
      - MYSQL_ROOT_PASSWORD=root
    ports:
     - "3306:3306"
    networks:
      vpcbr:
        ipv4_address: 10.5.0.5

  apigw-tomcat:
    container_name: apigw-tomcat
    build: tomcat/.
    ports:
     - "8080:8080"
     - "8009:8009"
    networks:
      vpcbr:
        ipv4_address: 10.5.0.6
    depends_on:
     - mysql

networks:
  vpcbr:
    driver: bridge
    ipam:
     config:
       - subnet: 10.5.0.0/16
         gateway: 10.5.0.1

There are 2 approach that I can found to this problem.

1. Update sdk tools with command window by accepting licence agreement as follows, just change the version according to your need.

   android update sdk --no-ui --filter build-tools-25.0.2,android-25,extra-android-m2repository

2. Second approach is copying licence folders to Android root directory. Goto your development machine open Android Studio. Find your sdk location from Project Structure menu. (C:\Users\UserName\AppData\Local\Android\sdk). Under that directory there must be a licence folder. Copy that folder with the content. Paste that folder in your Jenkins server machine (or where you face with this problem) under android sdk root folder. (C:\Users\UserName.jenkins\tools\android-sdk)

       this.setState(
        {
            originId: input.originId,
            destinationId: input.destinationId,
            radius: input.radius,
            search: input.search
        },
        function() { console.log("setState completed", this.state) }
       )

this might be helpful

Update July 1st 2019

docker-compose logs <name-of-service>

From the documentation:

Usage: logs [options] [SERVICE...]

Options:

--no-color Produce monochrome output.

-f, --follow Follow log output.

-t, --timestamps Show timestamps.

--tail="all" Number of lines to show from the end of the logs for each container.

See docker logs

You can start Docker compose in detached mode and attach yourself to the logs of all container later. If you're done watching logs you can detach yourself from the logs output without shutting down your services.

1. Use docker-compose up -d to start all services in detached mode (-d) (you won't see any logs in detached mode)
2. Use docker-compose logs -f -t to attach yourself to the logs of all running services, whereas -f means you follow the log output and the -t option gives you timestamps (See Docker reference)
3. Use Ctrl + z or Ctrl + c to detach yourself from the log output without shutting down your running containers

If you're interested in logs of a single container you can use the docker keyword instead:

1. Use docker logs -t -f <name-of-service>

Save the output

To save the output to a file you add the following to your logs command:

1. docker-compose logs -f -t >> myDockerCompose.log

This looks like an old thread but there is one more variant of how we can set an environment variable in the Gradle task.

task runSomeRandomTask(type: NpmTask, dependsOn: [npmInstall]) {
    environment = [ 'NODE_ENV': 'development', BASE_URL: '3000' ]
    args = ['run']
}

The above Gradle task integrates the Gradle and npm tasks.

This way we can pass multiple environment variables. Hope this helps to broaden the understanding which the answers above have already provided. Cheers!!

This answer is for docker-compose version 2 and it also works on version 3

You can still access the data when you use depends_on.

If you look at docker docs Docker Compose and Django, you still can access the database like this:

version: '2'
services:
  db:
    image: postgres
  web:
    build: .
    command: python manage.py runserver 0.0.0.0:8000
    volumes:
      - .:/code
    ports:
      - "8000:8000"
    depends_on:
      - db

What is the difference between links and depends_on?

links:

When you create a container for a database, for example:

docker run -d --name=test-mysql --env="MYSQL_ROOT_PASSWORD=mypassword" -P mysql

docker inspect d54cf8a0fb98 |grep HostPort

And you may find

"HostPort": "32777"

This means you can connect the database from your localhost port 32777 (3306 in container) but this port will change every time you restart or remove the container. So you can use links to make sure you will always connect to the database and don't have to know which port it is.

web:
  links:
   - db

depends_on:

I found a nice blog from Giorgio Ferraris Docker-compose.yml: from V1 to V2

When docker-compose executes V2 files, it will automatically build a network between all of the containers defined in the file, and every container will be immediately able to refer to the others just using the names defined in the docker-compose.yml file.

And

So we don’t need links anymore; links were used to start a network communication between our db container and our web-server container, but this is already done by docker-compose

Update

depends_on

Express dependency between services, which has two effects:

• docker-compose up will start services in dependency order. In the following example, db and redis will be started before web.
• docker-compose up SERVICE will automatically include SERVICE’s dependencies. In the following example, docker-compose up web will also create and start db and redis.

Simple example:

version: '2'
services:
  web:
    build: .
    depends_on:
      - db
      - redis
  redis:
    image: redis
  db:
    image: postgres

Note: depends_on will not wait for db and redis to be “ready” before starting web - only until they have been started. If you need to wait for a service to be ready, see Controlling startup order for more on this problem and strategies for solving it.

You will have to provide a link to your file that is accessible through the browser, that is for instance:

<a href="http://my.domain.com/Projecten/Protocollen/346/Uitvoeringsoverzicht.xls">

versus

<a href="C:/Projecten/Protocollen/346/Uitvoeringsoverzicht.xls">

If you expose your "Projecten" folder directly to the public, then you may only have to provide the link as such:

<a href="/Projecten/Protocollen/346/Uitvoeringsoverzicht.xls">

But beware, that your files can then be indexed by search engines, can be accessed by anybody having this link, etc.

I worked quite a long time with Flux and now quite a long time using Redux. As Dan pointed out both architectures are not so different. The thing is that Redux makes the things simpler and cleaner. It teaches you a couple of things on top of Flux. Like for example Flux is a perfect example of one-direction data flow. Separation of concerns where we have data, its manipulations and view layer separated. In Redux we have the same things but we also learn about immutability and pure functions.

First globally declare

Context mContext;

pass context with the constructor, by modifying it.

public FeedAdapter(List<Post> myDataset, Context context) {
    mDataset = myDataset;
    this.mContext = context;
}

then use the mContext whereever you need it

If you don't want to convert the entire Map into an array beforehand, and/or destructure key-value arrays, you can use this silly function:

/**_x000D_
 * Map over an ES6 Map._x000D_
 *_x000D_
 * @param {Map} map_x000D_
 * @param {Function} cb Callback. Receives two arguments: key, value._x000D_
 * @returns {Array}_x000D_
 */_x000D_
function mapMap(map, cb) {_x000D_
  let out = new Array(map.size);_x000D_
  let i = 0;_x000D_
  map.forEach((val, key) => {_x000D_
    out[i++] = cb(key, val);_x000D_
  });_x000D_
  return out;_x000D_
}_x000D_
_x000D_
let map = new Map([_x000D_
  ["a", 1],_x000D_
  ["b", 2],_x000D_
  ["c", 3]_x000D_
]);_x000D_
_x000D_
console.log(_x000D_
  mapMap(map, (k, v) => `${k}-${v}`).join(', ')_x000D_
); // a-1, b-2, c-3

Uninstalling and re-installing the NuGet package worked for me.

1. Remove any old reference from the project.

Execute this in the Package Manager Console:

2. UnInstall-Package Microsoft.AspNet.WebApi.Core -version 5.2.3
3. Install-Package Microsoft.AspNet.WebApi.Core -version 5.2.3

Live Plotting

import numpy as np
import matplotlib.pyplot as plt

x = np.linspace(0, 2 * np.pi, 100)
# plt.axis([x[0], x[-1], -1, 1])      # disable autoscaling
for point in x:
    plt.plot(point, np.sin(2 * point), '.', color='b')
    plt.draw()
    plt.pause(0.01)
# plt.clf()                           # clear the current figure

if the amount of data is too much you can lower the update rate with a simple counter

cnt += 1
if (cnt == 10):       # update plot each 10 points
    plt.draw()
    plt.pause(0.01)
    cnt = 0

Holding Plot after Program Exit

This was my actual problem that couldn't find satisfactory answer for, I wanted plotting that didn't close after the script was finished (like MATLAB),

If you think about it, after the script is finished, the program is terminated and there is no logical way to hold the plot this way, so there are two options

1. block the script from exiting (that's plt.show() and not what I want)
2. run the plot on a separate thread (too complicated)

this wasn't satisfactory for me so I found another solution outside of the box

SaveToFile and View in external viewer

For this the saving and viewing should be both fast and the viewer shouldn't lock the file and should update the content automatically

Selecting Format for Saving

vector based formats are both small and fast

• SVG is good but coudn't find good viewer for it except the web browser which by default needs manual refresh
• PDF can support vector formats and there are lightweight viewers which support live updating

Fast Lightweight Viewer with Live Update

For PDF there are several good options

• On Windows I use SumatraPDF which is free, fast and light (only uses 1.8MB RAM for my case)

• On Linux there are several options such as Evince (GNOME) and Ocular (KDE)

Sample Code & Results

Sample code for outputing plot to a file

import numpy as np
import matplotlib.pyplot as plt

x = np.linspace(0, 2 * np.pi, 100)
y = np.sin(2 * x)
plt.plot(x, y)
plt.savefig("fig.pdf")

after first run, open the output file in one of the viewers mentioned above and enjoy.

Here is a screenshot of VSCode alongside SumatraPDF, also the process is fast enough to get semi-live update rate (I can get near 10Hz on my setup just use time.sleep() between intervals)

If there is a Relation R(ABC)

-----------
|A | B | C |
-----------
|a | 1 | x |
|b | 1 | x |
|c | 1 | x |
|d | 2 | y |
|e | 2 | y |
|f | 3 | z |
|g | 3 | z |
 ----------
Given,
F1: A --> B 
F2: B --> C

The Primary Key and Candidate Key is: A

As the closure of A+ = {ABC} or R --- So only attribute A is sufficient to find Relation R.

DEF-1: From Some Definitions (unknown source) - A partial dependency is a dependency when prime attribute (i.e., an attribute that is a part(or proper subset) of Candidate Key) determines non-prime attribute (i.e., an attribute that is not the part (or subset) of Candidate Key).

Hence, A is a prime(P) attribute and B, C are non-prime(NP) attributes.

So, from the above DEF-1,

CONSIDERATION-1:: F1: A --> B (P determines NP) --- It must be Partial Dependency.

CONSIDERATION-2:: F2: B --> C (NP determines NP) --- Transitive Dependency.

What I understood from @philipxy answer (https://stackoverflow.com/a/25827210/6009502) is...

CONSIDERATION-1:: F1: A --> B; Should be fully functional dependency because B is completely dependent on A and If we Remove A then there is no proper subset of (for complete clarification consider L.H.S. as X NOT BY SINGLE ATTRIBUTE) that could determine B.

For Example: If I consider F1: X --> Y where X = {A} and Y = {B} then if we remove A from X; i.e., X - {A} = {}; and an empty set is not considered generally (or not at all) to define functional dependency. So, there is no proper subset of X that could hold the dependency F1: X --> Y; Hence, it is fully functional dependency.

F1: A --> B If we remove A then there is no attribute that could hold functional dependency F1. Hence, F1 is fully functional dependency not partial dependency.

If F1 were, F1: AC --> B;
and F2 were, F2: C --> B; 
then on the removal of A;
C --> B that means B is still dependent on C; 
we can say F1 is partial dependecy.

So, @philipxy answer contradicts DEF-1 and CONSIDERATION-1 that is true and crystal clear.

Hence, F1: A --> B is Fully Functional Dependency not partial dependency.

I have considered X to show left hand side of functional dependency because single attribute couldn't have a proper subset of attributes. Here, I am considering X as a set of attributes and in current scenario X is {A}

-- For the source of DEF-1, please search on google you may be able to hit similar definitions. (Consider that DEF-1 is incorrect or do not work in the above-mentioned example).

Remove /etc/my.cnf file and retry the installation, it worked for me for exactly same problem. :-)

I had same problem. I just solved it with declaring adapter public before onCreate of class.

PostAdapter postAdapter;

after that

postAdapter = new PostAdapter(getActivity(), posts);
recList.setAdapter(postAdapter);

at last I have called:

@Override
protected void onPostExecute(Void aVoid) {
    super.onPostExecute(aVoid);
    // Display the size of your ArrayList
    Log.i("TAG", "Size : " + posts.size());
    progressBar.setVisibility(View.GONE);
    postAdapter.notifyDataSetChanged();
}

May this will helps you.

In my opinion, deferreds/promises (as you have mentionned) is the way to go, rather than using timeouts.

Here is an example I have just written to demonstrate how you could do it using deferreds/promises.

Take some time to play around with deferreds. Once you really understand them, it becomes very easy to perform asynchronous tasks.

Hope this helps!

$(function(){
    function1().done(function(){
        // function1 is done, we can now call function2
        console.log('function1 is done!');

        function2().done(function(){
            //function2 is done
            console.log('function2 is done!');
        });
    });
});

function function1(){
    var dfrd1 = $.Deferred();
    var dfrd2= $.Deferred();

    setTimeout(function(){
        // doing async stuff
        console.log('task 1 in function1 is done!');
        dfrd1.resolve();
    }, 1000);

    setTimeout(function(){
        // doing more async stuff
        console.log('task 2 in function1 is done!');
        dfrd2.resolve();
    }, 750);

    return $.when(dfrd1, dfrd2).done(function(){
        console.log('both tasks in function1 are done');
        // Both asyncs tasks are done
    }).promise();
}

function function2(){
    var dfrd1 = $.Deferred();
    setTimeout(function(){
        // doing async stuff
        console.log('task 1 in function2 is done!');
        dfrd1.resolve();
    }, 2000);
    return dfrd1.promise();
}

Spring Data JPA by default looks for an EntityManagerFactory named entityManagerFactory. Check out this part of the Javadoc of EnableJpaRepositories or Table 2.1 of the Spring Data JPA documentation.

That means that you either have to rename your emf bean to entityManagerFactory or change your Spring configuration to:

<jpa:repositories base-package="your.package" entity-manager-factory-ref="emf" /> 

(if you are using XML)

or

@EnableJpaRepositories(basePackages="your.package", entityManagerFactoryRef="emf")

(if you are using Java Config)

The code snippet:

spyOn(myOtherService, "makeRemoteCallReturningPromise").and.callFake(function() {
    var deferred = $q.defer();
    deferred.resolve('Remote call result');
    return deferred.promise;
});

Can be written in a more concise form:

spyOn(myOtherService, "makeRemoteCallReturningPromise").and.returnValue(function() {
    return $q.resolve('Remote call result');
});

To start redis with a config file all you need to do is specifiy the config file as an argument:

redis-server /root/config/redis.rb

Instead of using and killing PID's I would suggest creating an init script for your service

I would suggest taking a look at the Installing Redis more properly section of http://redis.io/topics/quickstart. It will walk you through setting up an init script with redis so you can just do something like service redis_server start and service redis_server stop to control your server.

I am not sure exactly what distro you are using, that article describes instructions for a Debian based distro. If you are are using a RHEL/Fedora distro let me know, I can provide you with instructions for the last couple of steps, the config file and most of the other steps will be the same.

I can't find a scenario that cannot be solved using node-fibers. The example you provided using node-fibers behaves as expected. The key is to run all the relevant code inside a fiber, so you don't have to start a new fiber in random positions.

Lets see an example: Say you use some framework, which is the entry point of your application (you cannot modify this framework). This framework loads nodejs modules as plugins, and calls some methods on the plugins. Lets say this framework only accepts synchronous functions, and does not use fibers by itself.

There is a library that you want to use in one of your plugins, but this library is async, and you don't want to modify it either.

The main thread cannot be yielded when no fiber is running, but you still can create plugins using fibers! Just create a wrapper entry that starts the whole framework inside a fiber, so you can yield the execution from the plugins.

Downside: If the framework uses setTimeout or Promises internally, then it will escape the fiber context. This can be worked around by mocking setTimeout, Promise.then, and all event handlers.

So this is how you can yield a fiber until a Promise is resolved. This code takes an async (Promise returning) function and resumes the fiber when the promise is resolved:

framework-entry.js

console.log(require("./my-plugin").run());

async-lib.js

exports.getValueAsync = () => {
  return new Promise(resolve => {
    setTimeout(() => {
      resolve("Async Value");
    }, 100);
  });
};

my-plugin.js

const Fiber = require("fibers");

function fiberWaitFor(promiseOrValue) {
  var fiber = Fiber.current, error, value;
  Promise.resolve(promiseOrValue).then(v => {
    error = false;
    value = v;
    fiber.run();
  }, e => {
    error = true;
    value = e;
    fiber.run();
  });
  Fiber.yield();
  if (error) {
    throw value;
  } else {
    return value;
  }
}

const asyncLib = require("./async-lib");

exports.run = () => {
  return fiberWaitFor(asyncLib.getValueAsync());
};

my-entry.js

require("fibers")(() => {
  require("./framework-entry");
}).run();

When you run node framework-entry.js it will throw an error: Error: yield() called with no fiber running. If you run node my-entry.js it works as expected.

For Intellij go to View > Tool Windows > Gradle > Refresh All Projects (the blue circular arrows at the top of the Gradle window.

If you want all the dependencies in a single file at the end within two steps. Add this to your build.gradle.kts in the root of your project:

project.rootProject.allprojects {
    apply(plugin="project-report")

    this.task("allDependencies", DependencyReportTask::class) {
        evaluationDependsOnChildren()
        this.setRenderer(AsciiDependencyReportRenderer())
    }

}

Then apply:

./gradlew allDependencies | grep '\-\-\-' | grep -Po '\w+.*$' | awk -F ' ' '{ print $1 }' | sort | grep -v '\{' | grep -v '\[' | uniq | grep '.\+:.\+:.\+'

This will give you all the dependencies in your project and sub-projects along with all the 3rd party dependencies.

If you want to get this done in a programmatic way, then you'll need a custom renderer of the dependencies - you can start by extending the AsciiDependencyReportRenderer that prints an ascii graph of the dependencies by default.

Run cmd as administrator. Type iisreset. That's it.

Build up a JavaScript data structure with the required information, then turn it into the json string at the end.

Based on what I think you're doing, try something like this:

var result = [];
for (var name in goals) {
  if (goals.hasOwnProperty(name)) {
    result.push({name: name, goals: goals[name]});
  }
}

res.contentType('application/json');
res.send(JSON.stringify(result));

or something along those lines.

For Windows, you run dev at the command/ search program line and select Developer Command Prompt for VS. Then you are going to just run

csc

Now you get information similar to

Microsoft (R) Visual C# Compiler version 2.6.0.62329 (5429b35d)

For Windows and if you start with cmd terminal

cd C:\Windows\Microsoft.NET\Framework\
dir

Now you see all directories and files in .NET\Framework\ Please, select v... latest and go there, for example,

cd v4.0.30319

Run

csc

You will see information about version of C# compiler, that can be something similar to

Go to the Ant website and download. This way, you have a copy of Ant outside of Eclipse. I recommend to put it under the C:\ant directory. This way, it doesn't have any spaces in the directory names. In your System Control Panel, set the Environment Variable ANT_HOME to this directory, then pre-pend to the System PATHvariable, %ANT_HOME%\bin. This way, you don't have to put in the whole directory name.

Assuming you did the above, try this:

C:\> cd \Silk4J\Automation\iControlSilk4J
C:\Silk4J\Automation\iControlSilk4J> ant -d build

This will do several things:

• It will eliminate the possibility that the problem is with Eclipe's version of Ant.
• It is way easier to type
• Since you're executing the build.xml in the directory where it exists, you don't end up with the possibility that your Ant build can't locate a particular directory.

The -d will print out a lot of output, so you might want to capture it, or set your terminal buffer to something like 99999, and run cls first to clear out the buffer. This way, you'll capture all of the output from the beginning in the terminal buffer.

Let's see how Ant should be executing. You didn't specify any targets to execute, so Ant should be taking the default build target. Here it is:

<target depends="build-subprojects,build-project" name="build"/>

The build target does nothing itself. However, it depends upon two other targets, so these will be called first:

The first target is build-subprojects:

<target name="build-subprojects"/>

This does nothing at all. It doesn't even have a dependency.

The next target specified is build-project does have code:

<target depends="init" name="build-project">

This target does contain tasks, and some dependent targets. Before build-project executes, it will first run the init target:

<target name="init">
    <mkdir dir="bin"/>
    <copy includeemptydirs="false" todir="bin">
        <fileset dir="src">
            <exclude name="**/*.java"/>
        </fileset>
    </copy>
</target>

This target creates a directory called bin, then copies all files under the src tree with the suffix *.java over to the bin directory. The includeemptydirs mean that directories without non-java code will not be created.

Ant uses a scheme to do minimal work. For example, if the bin directory is created, the <mkdir/> task is not executed. Also, if a file was previously copied, or there are no non-Java files in your src directory tree, the <copy/> task won't run. However, the init target will still be executed.

Next, we go back to our previous build-project target:

<target depends="init" name="build-project">
    <echo message="${ant.project.name}: ${ant.file}"/>
    <javac debug="true" debuglevel="${debuglevel}" destdir="bin" source="${source}" target="${target}">
        <src path="src"/>
        <classpath refid="iControlSilk4J.classpath"/>
    </javac>
</target>

Look at this line:

<echo message="${ant.project.name}: ${ant.file}"/>

That should have always executed. Did your output print:

[echo] iControlSilk4J: C:\Silk4J\Automation\iControlSilk4J\build.xml

Maybe you didn't realize that was from your build.

After that, it runs the <javac/> task. That is, if there's any files to actually compile. Again, Ant tries to avoid work it doesn't have to do. If all of the *.java files have previously been compiled, the <javac/> task won't execute.

And, that's the end of the build. Your build might not have done anything simply because there was nothing to do. You can try running the clean task, and then build:

C:\Silk4J\Automation\iControlSilk4J> ant -d clean build

However, Ant usually prints the target being executed. You should have seen this:

init:

build-subprojects:

build-projects:

    [echo] iControlSilk4J: C:\Silk4J\Automation\iControlSilk4J\build.xml

build:

Build Successful

Note that the targets are all printed out in order they're executed, and the tasks are printed out as they are executed. However, if there's nothing to compile, or nothing to copy, then you won't see these tasks being executed. Does this look like your output? If so, it could be there's nothing to do.

• If the bin directory already exists, <mkdir/> isn't going to execute.
• If there are no non-Java files in src, or they have already been copied into bin, the <copy/> task won't execute.
• If there are no Java file in your src directory, or they have already been compiled, the <java/> task won't run.

If you look at the output from the -d debug, you'll see Ant looking at a task, then explaining why a particular task wasn't executed. Plus, the debug option will explain how Ant decides what tasks to execute.

See if that helps.

I had issue with the solutions mentioned above as specifying the string key would give me javax.el.PropertyNotFoundException. The code shown below worked for me. In this I used status to count the index of for each loop and displayed the value of index I am interested on

<c:forEach items="${requestScope.key}"  var="map" varStatus="status" >
    <c:if test="${status.index eq 1}">
        <option><c:out value=${map.value}/></option>
    </c:if>
</c:forEach>    

You can also do like this ....

<?php  $countryname = $all_meta_for_user['country']; ?>

<select id="mycountry"  name="country" class="user">

    <?php $myrows = $wpdb->get_results( "SELECT * FROM wp_countries order by country_name" );
    foreach($myrows as $rows){
        if( $countryname == $rows->id ){ 
            echo "<option selected = 'selected' value='".$rows->id."'>".$rows->country_name."</option>";
        } else{ 
            echo "<option value='".$rows->id."'>".$rows->country_name."</option>";
        }
    }
    ?>
</select>

<table style="border:2px solid #ddedde">
    <tr>
        <td style="border:2px solid #ddedde;width:50%">a</td>
        <td style="border:2px solid #ddedde;width:20%">b</td>
        <td style="border:2px solid #ddedde;width:30%">c</td>
    </tr>
    <tr>
        <td style="border:2px solid #ddedde;width:50%">a</td>
        <td style="border:2px solid #ddedde;width:20%">b</td>
        <td style="border:2px solid #ddedde;width:30%">c</td>
    </tr>
</table>

Use toString when you need to display the name to the user.

Use name when you need the name for your program itself, e.g. to identify and differentiate between different enum values.

Definition: An imperative language uses a sequence of statements to determine how to reach a certain goal. These statements are said to change the state of the program as each one is executed in turn.

Examples: Java is an imperative language. For example, a program can be created to add a series of numbers:

 int total = 0;
 int number1 = 5;
 int number2 = 10;
 int number3 = 15;
 total = number1 + number2 + number3; 

Each statement changes the state of the program, from assigning values to each variable to the final addition of those values. Using a sequence of five statements the program is explicitly told how to add the numbers 5, 10 and 15 together.

Functional languages: The functional programming paradigm was explicitly created to support a pure functional approach to problem solving. Functional programming is a form of declarative programming.

Advantages of Pure Functions: The primary reason to implement functional transformations as pure functions is that pure functions are composable: that is, self-contained and stateless. These characteristics bring a number of benefits, including the following: Increased readability and maintainability. This is because each function is designed to accomplish a specific task given its arguments. The function does not rely on any external state.

Easier reiterative development. Because the code is easier to refactor, changes to design are often easier to implement. For example, suppose you write a complicated transformation, and then realize that some code is repeated several times in the transformation. If you refactor through a pure method, you can call your pure method at will without worrying about side effects.

Easier testing and debugging. Because pure functions can more easily be tested in isolation, you can write test code that calls the pure function with typical values, valid edge cases, and invalid edge cases.

For OOP People or Imperative languages:

Object-oriented languages are good when you have a fixed set of operations on things and as your code evolves, you primarily add new things. This can be accomplished by adding new classes which implement existing methods and the existing classes are left alone.

Functional languages are good when you have a fixed set of things and as your code evolves, you primarily add new operations on existing things. This can be accomplished by adding new functions which compute with existing data types and the existing functions are left alone.

Cons:

It depends on the user requirements to choose the way of programming, so there is harm only when users don’t choose the proper way.

When evolution goes the wrong way, you have problems:

• Adding a new operation to an object-oriented program may require editing many class definitions to add a new method
• Adding a new kind of thing to a functional program may require editing many function definitions to add a new case.

This error might be because of an attribute left empty in the manifest file.

An example:

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:logo="@drawable/ic_actionbar"
    android:supportsRtl="true"
    android:fullBackupContent="">
...
</application>

The fullBackupContent is empty in the above example.

When it's changed to android:fullBackupContent="true" it will be fixed.

Try to change like this ..

firstStr = "<?xml version" 'my file always starts like this

Do until objInputFile.AtEndOfStream  

    strToAdd = "<tr><td><a href=" & chr(34) & "../../Logs/DD/Beginning_of_DD_TC" & CStr(index) & ".html" & chr(34) & ">Beginning_of_DD_TC" & CStr(index) & "</a></td></tr>"  

   substrToFind = "<tr><td><a href=" & chr(34) & "../Test case " & trim(cstr((index)))

   tmpStr = objInputFile.ReadLine

   If InStr(tmpStr, substrToFind) <= 0 Then
       If Instr(tmpStr, firstStr) > 0 Then
          text = tmpStr 'to avoid the first empty line
       Else
          text = text & vbCrLf & tmpStr
       End If
   Else
      text = text & vbCrLf & strToAdd & vbCrLf & tmpStr

   End If
   index = index + 1
Loop

I've tried the solution presented in the accepted answer and it did not work for me. I wanted to share what DID work for me as it might help someone else. I've found this solution here.

Basically what you need to do is put your .so files inside a a folder named lib (Note: it is not libs and this is not a mistake). It should be in the same structure it should be in the APK file.

In my case it was:
Project:
|--lib:
|--|--armeabi:
|--|--|--.so files.

So I've made a lib folder and inside it an armeabi folder where I've inserted all the needed .so files. I then zipped the folder into a .zip (the structure inside the zip file is now lib/armeabi/*.so) I renamed the .zip file into armeabi.jar and added the line compile fileTree(dir: 'libs', include: '*.jar') into dependencies {} in the gradle's build file.

This solved my problem in a rather clean way.

Interesting info about MSCorlib:

• The .NET 2.0 assembly will reference and use the 2.0 mscorlib.The .NET 1.1 assembly will reference the 1.1 mscorlib but will use the 2.0 mscorlib at runtime (due to hard-coded version redirects in theruntime itself)
• In GAC there is only one version of mscorlib, you dont find 1.1 version on GAC even if you have 1.1 framework installed on your machine. It would be good if somebody can explain why MSCorlib 2.0 alone is in GAC whereas 1.x version live inside framework folder
• Is it possible to force a different runtime to be loaded by the application by making a config setting in your app / web.config? you won’t be able to choose the CLR version by settings in the ConfigurationFile – at that point, a CLR will already be running, and there can only be one per process. Immediately after the CLR is chosen the MSCorlib appropriate for that CLR is loaded.

Another possibility is to select the Install Dependencies checkbox In the R package installer, on the bottom right:

time difference between now and 10 minutes later using momentjs

let start_time = moment().format('YYYY-MM-DD HH:mm:ss');
let next_time = moment().add(10, 'm').format('YYYY-MM-DD HH:mm:ss');

let diff_milliseconds = Date.parse(next_time) - Date.parse(star_time);
let diff_seconds = diff_milliseconds * 1000;

Create a (local) repository and use yum to have it resolve the dependencies for you.

The CentOS wiki has a nice page providing a how-to on this. CentOS wiki HowTos/CreateLocalRepos.

Summarized and further minimized (not ideal, but quickest):

1. Create a directory for you local repository, e.g. /home/user/repo.
2. Move the RPMs into that directory.

3. Fix some ownership and filesystem permissions:

   # chown -R root.root /home/user/repo
   

4. Install the createrepo package if not installed yet, and run

   # createrepo /home/user/repo
   # chmod -R o-w+r /home/user/repo
   

5. Create a repository configuration file, e.g. /etc/yum.repos.d/myrepo.repo containing

   [local]
   name=My Awesome Repo
   baseurl=file:///home/user/repo
   enabled=1
   gpgcheck=0
   

6. Install your package using

   # yum install packagename
   

Two things must be done.

First add the directory to be included:

target_include_directories(test PRIVATE ${YOUR_DIRECTORY})

In case you are stuck with a very old CMake version (2.8.10 or older) without support for target_include_directories, you can also use the legacy include_directories instead:

include_directories(${YOUR_DIRECTORY})

Then you also must add the header files to the list of your source files for the current target, for instance:

set(SOURCES file.cpp file2.cpp ${YOUR_DIRECTORY}/file1.h ${YOUR_DIRECTORY}/file2.h)
add_executable(test ${SOURCES})

This way, the header files will appear as dependencies in the Makefile, and also for example in the generated Visual Studio project, if you generate one.

How to use those header files for several targets:

set(HEADER_FILES ${YOUR_DIRECTORY}/file1.h ${YOUR_DIRECTORY}/file2.h)

add_library(mylib libsrc.cpp ${HEADER_FILES})
target_include_directories(mylib PRIVATE ${YOUR_DIRECTORY})
add_executable(myexec execfile.cpp ${HEADER_FILES})
target_include_directories(myexec PRIVATE ${YOUR_DIRECTORY})

name() is literally the textual name in the java code of the enum. That means it is limited to strings that can actually appear in your java code, but not all desirable strings are expressible in code. For example, you may need a string that begins with a number. name() will never be able to obtain that string for you.

For Windows you can use

(if exist node_modules rmdir node_modules /q /s) && npm install

which removes node_modules directory and performs npm install then. Removal before install assures that all packages are reinstalled.

#change-avatar-file is a file input #change-avatar-file is a img tag (the target of jcrop) The "key" is FR.onloadend Event https://developer.mozilla.org/en-US/docs/Web/API/FileReader

                    jcrop_api = this;
                });
            }
        }
    });

Another case for when to use HttpResponseException instead of Response.CreateResponse(HttpStatusCode.NotFound), or other error status code, is if you have transactions in action filters and you want the transactions to be rolled back when returning an error response to the client.

Using Response.CreateResponse will not roll the transaction back, whereas throwing an exception will.

This was my solution:

I added required to the select tag:

                <div class="col-lg-10">
                <select class="form-control" name="HoursEntry" id="HoursEntry" required>
                    <option value="">Select.....</option>
                    <option value="0.25">0.25</option>
                    <option value="0.5">0.50</option>
                    <option value="1">1.00</option>
                    <option value="1.25">1.25</option>
                    <option value="1.5">1.50</option>
                    <option value="2">2.00</option>
                    <option value="2.25">2.25</option>
                    <option value="2.5">2.50</option>
                    <option value="3">3.00</option>
                    <option value="3.25">3.25</option>
                    <option value="3.5">3.50</option>
                    <option value="4">4.00</option>
                    <option value="4.25">4.25</option>
                    <option value="4.5">4.50</option>
                    <option value="5">5.00</option>
                    <option value="5.25">5.25</option>
                    <option value="5.5">5.50</option>
                    <option value="6">6.00</option>
                    <option value="6.25">6.25</option>
                    <option value="6.5">6.50</option>
                    <option value="7">7.00</option>
                    <option value="7.25">7.25</option>
                    <option value="7.5">7.50</option>
                    <option value="8">8.00</option>
                </select>

Use this:

mysqli_query($this->db_link, $query) or die(mysqli_error($this->db_link)); 
# mysqli_query($link,$query) returns 0 if there's an error.
# mysqli_error($link) returns a string with the last error message

You can also use this to print the error code.

echo mysqli_errno($this->db_link);

Take a look here and here

We should also consider that the SVM system can be applied directly to non-metric spaces, such as the set of labeled graphs or strings. In fact, the internal kernel function can be generalized properly to virtually any kind of input, provided that the positive definiteness requirement of the kernel is satisfied. On the other hand, to be able to use an ANN on a set of labeled graphs, explicit embedding procedures must be considered.

Is the size of C “int” 2 bytes or 4 bytes?

The answer is "yes" / "no" / "maybe" / "maybe not".

The C programming language specifies the following: the smallest addressable unit, known by char and also called "byte", is exactly CHAR_BIT bits wide, where CHAR_BIT is at least 8.

So, one byte in C is not necessarily an octet, i.e. 8 bits. In the past one of the first platforms to run C code (and Unix) had 4-byte int - but in total int had 36 bits, because CHAR_BIT was 9!

int is supposed to be the natural integer size for the platform that has range of at least -32767 ... 32767. You can get the size of int in the platform bytes with sizeof(int); when you multiply this value by CHAR_BIT you will know how wide it is in bits.

While 36-bit machines are mostly dead, there are still platforms with non-8-bit bytes. Just yesterday there was a question about a Texas Instruments MCU with 16-bit bytes, that has a C99, C11-compliant compiler.

On TMS320C28x it seems that char, short and int are all 16 bits wide, and hence one byte. long int is 2 bytes and long long int is 4 bytes. The beauty of C is that one can still write an efficient program for a platform like this, and even do it in a portable manner!

Are you trying to run your .exe file from the cmd? This was my mistake. Just run the .exe file by double clicking it. If it's a .NET Core SCD for Windows 8.1/Windows Server 2012 R2 x64.

Another correct way to get selected value would be using this selector:

$("option[value="0"]:selected")

Best for you!

Rendering engine goes several steps till it paints anything on the screen.

it looks like this:

1. Converting HTML bytes to characters depending on encoding we set to the document;
2. Tokens are created according to characters. Tokens mean analyze characters and specify opening tangs and nested tags;
3. From tokens separated nodes are created. they are objects and according to information delivered from tokenization process, engine creates objects which includes all necessary information about each node;
4. after that DOM is created. DOM is tree data structure and represents whole hierarchy and information about relationship and specification of tags;

The same process goes to CSS. for CSS rendering engine creates different/separated data structure for CSS but it's called CSSOM (CSS Object Model)

Browser works only with Object models so it needs to know all information about DOM and CSSDOM.

The next step is combining somehow DOM and CSSOM. because without CSSOM browser do not know how to style each element during rendering process.

All information above means that, anything you provide in your html (javascript, css ) browser will pause DOM construction process. If you are familiar with event loop, there is simple rule how event loop executes tasks:

1. Execute macro tasks;
2. execute micro tasks;
3. Rendering;

So when you provide Javascript file, browser do not know what JS code is going to do and stops all DOM construction process and Javascript interptreter starts parsing and executing Javascript code.

Even you provide Javascript in the end of body tag, Browser will proceed all above steps to HTML and CSS but except rendering. it will find out Script tag and will stop until JS is done.

But HTML provided two additional options for script tag: async and defer.

Async - means execute code when it is downloaded and do not block DOM construction during downloading process.

Defer - means execute code after it's downloaded and browser finished DOM construction and rendering process.

Good list. The Angry Ninjas Starter Kit will have a Cocos2d-X update soon.

I think you can find your answer here : Is an anchor tag without the href attribute safe?

Also if you want to no link operation with href , you can use it like :

<a href="javascript:void(0);">something</a>

my solution is quite the same as Pumbaa80's one, but I suggest to use display: table instead of display:table-row for li element. So it will be something like this:

ol {
    counter-reset: foo; /* default display:list-item */
}

ol > li {
    counter-increment: foo;
    display: table; /* instead of table-row */
}

ol > li::before {
    content: counter(foo) ".";
    display: table-cell;
    text-align: right;
}

So now we can use margins for spacing between li's

Yes, you can. Here is an example.

SELECT a.*
FROM TableA a
LEFT OUTER JOIN TableB j1 ON  (CASE WHEN LEN(COALESCE(a.NoBatiment, '')) = 3 
                                THEN RTRIM(a.NoBatiment) + '0' 
                                ELSE a.NoBatiment END ) = j1.ColumnName 

Coffeescript doesn't support javascript ternary operator. Here is the reason from the coffeescript author:

I love ternary operators just as much as the next guy (probably a bit more, actually), but the syntax isn't what makes them good -- they're great because they can fit an if/else on a single line as an expression.

Their syntax is just another bit of mystifying magic to memorize, with no analogue to anything else in the language. The result being equal, I'd much rather have if/elses always look the same (and always be compiled into an expression).

So, in CoffeeScript, even multi-line ifs will compile into ternaries when appropriate, as will if statements without an else clause:

if sunny   
  go_outside() 
else   
  read_a_book().

if sunny then go_outside() else read_a_book()

Both become ternaries, both can be used as expressions. It's consistent, and there's no new syntax to learn. So, thanks for the suggestion, but I'm closing this ticket as "wontfix".

I solved this warning changing "Configuration Manager" to Release (Mixed Plataform).

In android gradle 0.4.0 you can just do:

println System.env.HOME

classpath com.android.tools.build:gradle-experimental:0.4.0

I had the same problem on ios7. I called it in selector and it worked on both ios7 and ios8.

[self performSelector: @selector(showMainView) withObject: nil afterDelay: 0.0];

- (void) showMainView {
    HomeViewController * homeview = [
        [HomeViewController alloc] initWithNibName: @
        "HomeViewController"
        bundle: nil];
    UINavigationController * navcont = [
        [UINavigationController alloc] initWithRootViewController: homeview];
    navcont.navigationBar.tintColor = [UIColor whiteColor];
    navcont.navigationBar.barTintColor = App_Theme_Color;
    [navcont.navigationBar
    setTitleTextAttributes: @ {
        NSForegroundColorAttributeName: [UIColor whiteColor]
    }];
    navcont.modalPresentationStyle = UIModalPresentationFullScreen;
    navcont.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
    [self.navigationController presentViewController: navcont animated: YES completion: ^ {

    }];
}

This is a really annoying one. What I ended up using is this:

First, create a group of simple buttons with no data-toggle attribute.

<div id="selector" class="btn-group">
    <button type="button" class="btn active">Day</button>
    <button type="button" class="btn">Week</button>
    <button type="button" class="btn">Month</button>
    <button type="button" class="btn">Year</button>
</div>

Next, write an event handler that simulates the radio button effect by 'activating' the clicked one and 'deactivating' all other buttons. (EDIT: Integrated Nick's cleaner version from the comments.)

$('#selector button').click(function() {
    $(this).addClass('active').siblings().removeClass('active');

    // TODO: insert whatever you want to do with $(this) here
});

The DLL has to be in the bin folder.

In Visual Studio, I add the dll to my project (NOT in References, but "Add existing file"). Then set the "Copy to Output Directory" Property for the dll to "Copy if newer".

I cannot replicate the results discussed here.

I don't know if poor benchmark code is to blame, or what, but the two methods are within 10% of each other on my machine using the following code, and one loop is usually just slightly faster than two - as you'd expect.

Array sizes ranged from 2^16 to 2^24, using eight loops. I was careful to initialize the source arrays so the += assignment wasn't asking the FPU to add memory garbage interpreted as a double.

I played around with various schemes, such as putting the assignment of b[j], d[j] to InitToZero[j] inside the loops, and also with using += b[j] = 1 and += d[j] = 1, and I got fairly consistent results.

As you might expect, initializing b and d inside the loop using InitToZero[j] gave the combined approach an advantage, as they were done back-to-back before the assignments to a and c, but still within 10%. Go figure.

Hardware is Dell XPS 8500 with generation 3 Core i7 @ 3.4 GHz and 8 GB memory. For 2^16 to 2^24, using eight loops, the cumulative time was 44.987 and 40.965 respectively. Visual C++ 2010, fully optimized.

PS: I changed the loops to count down to zero, and the combined method was marginally faster. Scratching my head. Note the new array sizing and loop counts.

I'm not sure why it was decided that MFLOPS was a relevant metric. I though the idea was to focus on memory accesses, so I tried to minimize the amount of floating point computation time. I left in the +=, but I am not sure why.

A straight assignment with no computation would be a cleaner test of memory access time and would create a test that is uniform irrespective of the loop count. Maybe I missed something in the conversation, but it is worth thinking twice about. If the plus is left out of the assignment, the cumulative time is almost identical at 31 seconds each.

Your pizza can have exactly three topping types:

• one type of cheese
• one type of meat
• one type of vegetable

So we order two pizzas and choose the following toppings:

Pizza    Topping     Topping Type
-------- ----------  -------------
1        mozzarella  cheese
1        pepperoni   meat
1        olives      vegetable
2        mozzarella  meat
2        sausage     cheese
2        peppers     vegetable

Wait a second, mozzarella can't be both a cheese and a meat! And sausage isn't a cheese!

We need to prevent these sorts of mistakes, to make mozzarella always be cheese. We should use a separate table for this, so we write down that fact in only one place.

Pizza    Topping
-------- ----------
1        mozzarella
1        pepperoni
1        olives
2        mozzarella 
2        sausage
2        peppers

Topping     Topping Type
----------  -------------
mozzarella  cheese
pepperoni   meat
olives      vegetable
sausage     meat
peppers     vegetable

That was the explanation that an 8 year-old might understand. Here is the more technical version.

BCNF acts differently from 3NF only when there are multiple overlapping candidate keys.

The reason is that the functional dependency X -> Y is of course true if Y is a subset of X. So in any table that has only one candidate key and is in 3NF, it is already in BCNF because there is no column (either key or non-key) that is functionally dependent on anything besides that key.

Because each pizza must have exactly one of each topping type, we know that (Pizza, Topping Type) is a candidate key. We also know intuitively that a given topping cannot belong to different types simultaneously. So (Pizza, Topping) must be unique and therefore is also a candidate key. So we have two overlapping candidate keys.

I showed an anomaly where we marked mozarella as the wrong topping type. We know this is wrong, but the rule that makes it wrong is a dependency Topping -> Topping Type which is not a valid dependency for BCNF for this table. It's a dependency on something other than a whole candidate key.

So to solve this, we take Topping Type out of the Pizzas table and make it a non-key attribute in a Toppings table.

"if(true)" will always be true and it will never make it to the else. If you want it to work correctly you have to do this:

int reply = JOptionPane.showConfirmDialog(null, message, title, JOptionPane.YES_NO_OPTION);
if (reply == JOptionPane.YES_OPTION) {
    JOptionPane.showMessageDialog(null, "HELLO");
} else {
    JOptionPane.showMessageDialog(null, "GOODBYE");
    System.exit(0);
}

Type listType = new TypeToken<List<Post>>() {}.getType();
List<Post> posts = new Gson().fromJson(jsonOutput.toString(), listType);

The usual solution is to create a class which manages the access to this environmental variable, which you can then mock in your test class.

public class Environment {
    public String getVariable() {
        return System.getenv(); // or whatever
    }
}

public class ServiceTest {
    private static class MockEnvironment {
        public String getVariable() {
           return "foobar";
        }
    }

    @Test public void testService() {
        service.doSomething(new MockEnvironment());
    }
}

The class under test then gets the environment variable using the Environment class, not directly from System.getenv().

This is all you need:

background-repeat: no-repeat;

Thanks to Ali Tokmen answer. I managed to force delete the specific local dependency with the following command:

mvn dependency:purge-local-repository -DmanualInclude=com.skyfish:utils

With this, it removes utils from my .m2/repository and it always re-download the utils JAR dependency when I run mvn clean install.

The first set of errors, for the missing vtable, are caused because you do not implement takeaway::textualGame(); instead you implement a non-member function, textualGame(). I think that adding the missing takeaway:: will fix that.

The cause of the last error is that you're calling a virtual function, initialData(), from the constructor of gameCore. At this stage, virtual functions are dispatched according to the type currently being constructed (gameCore), not the most derived class (takeaway). This particular function is pure virtual, and so calling it here gives undefined behaviour.

Two possible solutions:

• Move the initialisation code for gameCore out of the constructor and into a separate initialisation function, which must be called after the object is fully constructed; or
• Separate gameCore into two classes: an abstract interface to be implemented by takeaway, and a concrete class containing the state. Construct takeaway first, and then pass it (via a reference to the interface class) to the constructor of the concrete class.

I would recommend the second, as it is a move towards smaller classes and looser coupling, and it will be harder to use the classes incorrectly. The first is more error-prone, as there is no way be sure that the initialisation function is called correctly.

One final point: the destructor of a base class should usually either be virtual (to allow polymorphic deletion) or protected (to prevent invalid polymorphic deletion).

Other answers didn't work for me, but this did (in fish shell):

brew remove <package>
for p in (brew deps <package>)
    brew remove $p
end

Because brew remove $p fails when some other package depends on p.

Ok to generalize the technique of how many bits you need to represent a number is done this way. You have R symbols for a representation and you want to know how many bits, solve this equation R=2^n or log2(R)=n. Where n is the numbers of bits and R is the number of symbols for the representation.

For the decimal number system R=9 so we solve 9=2^n, the answer is 3.17 bits per decimal digit. Thus a 3 digit number will need 9.51 bits or 10. A 1000 digit number needs 3170 bits

Check if tools.jar used during compilation complies with the JRE set. If you are on eclipse, verify the versions as:
Goto Window->Preferences
- Check Ant Runtime by selecting Runtime under Ant in the left pane. Check the Global Entries under classpath tab. You can see the version in folder path.
- On the left pane check installed JREs under Java. Check the version.
I had also got the same problem when my selected JRE was 1.6.0_24 and tools.jar in Ant runtime was coming from jdk 1.7 If both of them are from different versions- 1.6/1.7, correct them by correcting their path. Typically, tools.jar can be found at :C:\Program Files\Java\jdk1.x.x\lib. Likewise if required add the JRE by pointing it to C:\Program Files\Java\jdk1.x.x\

I only want to cover second point of the question that is related to performance, because no body else has covered this. Select Into is a lot more faster than insert into, when it comes to tables with large datasets. I prefer select into when I have to read a very large table. insert into for a table with 10 million rows may take hours while select into will do this in minutes, and as for as losing indexes on new table is concerned you can recreate the indexes by query and can still save a lot more time when compared to insert into.

I have added below code to terminate tasks you can use it. You may change the retry numbers.

I would like to show another cross-browser way which can solve this question using CSS3 calc().

We can use the calc() function to control the margin-top property of the child div when it's positioned absolute relative to the parent div.

The main advantage using calc() is that the parent element height can be changed at anytime and the child div will always be aligned to the middle.

The margin-top calculation is made dynamically (by css and not by a script and it's a very big advantage).

Check out this LIVE DEMO

I created a bin directory at the project_dir level, then created a release/debug directory inside the bin folder, which solved the problem for me.

Could do it with :contains() selector as well:

Also worth taking a look at is the default stylesheet for HTML 4. The W3C recommends using these styles as the default. An abridged excerpt:

h1 { font-size: 2em; }
h2 { font-size: 1.5em; }
h3 { font-size: 1.17em; }
h4 { font-size: 1.12em; }
h5 { font-size: .83em; }
h6 { font-size: .75em; }

Hope this information is helpful.

You need to load your JNI library.

System.loadLibrary loads the DLL from the JVM path (JDK bin path).

If you want to load an explicit file with a path, use System.load()

So left div style depends on the presence of right div. I can't think of a CSS selector allowing that kind of behavior yet.

Thus it seems to me that you'll need to programmatically add a class server side (or in JS) on parent div or left div to do that.

<div id="parent twocols">
  <div class="left"></div>
  <div class="right"></div>
</div>

or

<div id="parent">
  <div class="left"></div>
</div>

So right style is always :

.right {
    float: right;
    width: 200px; /* or whatever value you need */
    /* margin and padding at your discretion */
}

and left style is :

.parent.twocols .left {
    margin-right: 200px; /* according to right div width + margin + padding*/
}

DotNetZip is your friend here.

As easy as:

using (ZipFile zip = ZipFile.Read(ExistingZipFile))
{
  ZipEntry e = zip["MyReport.doc"];
  e.Extract(OutputStream);
}

(you can also extract to a file or other destinations).

Reading the zip file's table of contents is as easy as:

using (ZipFile zip = ZipFile.Read(ExistingZipFile))
{
  foreach (ZipEntry e in zip)
  {
    if (header)
    {
      System.Console.WriteLine("Zipfile: {0}", zip.Name);
      if ((zip.Comment != null) && (zip.Comment != "")) 
        System.Console.WriteLine("Comment: {0}", zip.Comment);
      System.Console.WriteLine("\n{1,-22} {2,8}  {3,5}   {4,8}  {5,3} {0}",
                               "Filename", "Modified", "Size", "Ratio", "Packed", "pw?");
      System.Console.WriteLine(new System.String('-', 72));
      header = false;
    }
    System.Console.WriteLine("{1,-22} {2,8} {3,5:F0}%   {4,8}  {5,3} {0}",
                             e.FileName,
                             e.LastModified.ToString("yyyy-MM-dd HH:mm:ss"),
                             e.UncompressedSize,
                             e.CompressionRatio,
                             e.CompressedSize,
                             (e.UsesEncryption) ? "Y" : "N");

  }
}

Edited To Note: DotNetZip used to live at Codeplex. Codeplex has been shut down. The old archive is still available at Codeplex. It looks like the code has migrated to Github:

• https://github.com/DinoChiesa/DotNetZip. Looks to be the original author's repo.
• https://github.com/haf/DotNetZip.Semverd. This looks to be the currently maintained version. It's also packaged up an available via Nuget at https://www.nuget.org/packages/DotNetZip/

From what you've told us it does appear to be a false positive in valgrind. The new syntax with () should value-initialize the object, assuming it is POD.

Is it possible that some subpart of your struct isn't actually POD and that's preventing the expected initialization? Are you able to simplify your code into a postable example that still flags the valgrind error?

Alternately perhaps your compiler doesn't actually value-initialize POD structures.

In any case probably the simplest solution is to write constructor(s) as needed for the struct/subparts.

As many people have commented, responsive design very often sets width by %

width:inherit will inherit the CSS width NOT the computed width -- Which means the child container inherits width:100%

But, I think, almost as often responsive design sets max-width too, therefore:

#container {
    width:100%;
    max-width:800px;
}
#contained {
    position:fixed;
    width:inherit;
    max-width:inherit;
}

This worked very satisfyingly to solve my problem of making a sticky menu be restrained to the original parent width whenever it got "stuck"

Both the parent and child will adhere to the width:100% if the viewport is less than the maximum width. Likewise, both will adhere to the max-width:800px when the viewport is wider.

It works with my already responsive theme in a way that I can alter the parent container without having to also alter the fixed child element -- elegant and flexible

ps: I personally think it does not matter one bit that IE6/7 do not use inherit

Short answer: No.

But you might be able to do it with a bit of filthing. If you open up a test page (with GET) then evaluate some JavaScript on that page you should be able to replicate a POST request. See JavaScript post request like a form submit to see how you can replicate a POST request in JavaScript.

Hope this helps.

The negative margin trick:

http://pastehtml.com/view/1dujbt3.html

Not elegant, I suppose, but it works in some cases.

Create an attribute that contains a list of the parameters, like so:

<script src="http://path/to/widget.js" data-params="1, 3"></script>

Then, in your JavaScript, get the parameters as an array:

var script = document.currentScript || 
/*Polyfill*/ Array.prototype.slice.call(document.getElementsByTagName('script')).pop();

var params = (script.getAttribute('data-params') || '').split(/, */);

params[0]; // -> 1
params[1]; // -> 3

For those of us using ASP.NET MVC 4 - this may be helpful.

First, I added a BundleConfig class in the App_Start folder.

Here’s my code that I used to create it:

using System.Web.Optimization;

public class BundleConfig
{
    public static void RegisterBundles(BundleCollection bundles)
    {
        bundles.Add(new StyleBundle("~/Content/css").Include("~/Content/SiteMaster.css"));
    }
}

Second, I registered the BundleConfig class in the Global.asax file:

protected void Application_Start()
{
    BundleConfig.RegisterBundles(BundleTable.Bundles);
}

Third, I added style helpers to the my CSS file:

/* Styles for validation helpers */
.field-validation-error {
    color: red;
    font-weight: bold;
}

.field-validation-valid {
    display: none;
}

input.input-validation-error {
    border: 1px solid #e80c4d;
}

input[type="checkbox"].input-validation-error {
    border: 0 none;
}

.validation-summary-errors {
    color: #e80c4d;
    font-weight: bold;
    font-size: 1.1em;
}

.validation-summary-valid {
    display: none;
}

Finally I used this syntax in any View:

@Styles.Render("~/Content/css")

There is nothing like Silver Bullet. Everything comes with some cost associated with it. It is like if you eat oily food, you will compromise your health and healthy food does not come with spices like oily food. It is individual choice whether they want health or spices as in their food. Same way Node.js consider to be used in specific scenario. If your app does not fit into that scenario you should not consider it for your app development. I am just putting my thought on the same:

When to use Node.JS

1. If your server side code requires very few cpu cycles. In other world you are doing non blocking operation and does not have heavy algorithm/Job which consumes lots of CPU cycles.
2. If you are from Javascript back ground and comfortable in writing Single Threaded code just like client side JS.

When NOT to use Node.JS

1. Your server request is dependent on heavy CPU consuming algorithm/Job.

Scalability Consideration with Node.JS

1. Node.JS itself does not utilize all core of underlying system and it is single threaded by default, you have to write logic by your own to utilize multi core processor and make it multi threaded.

Node.JS Alternatives

There are other option to use in place of Node.JS however Vert.x seems to be pretty promising and has lots of additional features like polygot and better scalability considerations.

If your close button is going to be text, this works very well for me:

#close {
  position: fixed;
  width: 70%; /* the width of the parent */
  text-align: right;
}
#close span {
  cursor: pointer;
}

Then your HTML can just be:

<div id="close"><span id="x">X</span></div>

Specifying the path to the DLL file in your project's settings does not ensure that your application will find the DLL at run-time. You only told Visual Studio how to find the files it needs. That has nothing to do with how the program finds what it needs, once built.

Placing the DLL file into the same folder as the executable is by far the simplest solution. That's the default search path for dependencies, so you won't need to do anything special if you go that route.
To avoid having to do this manually each time, you can create a Post-Build Event for your project that will automatically copy the DLL into the appropriate directory after a build completes.

Alternatively, you could deploy the DLL to the Windows side-by-side cache, and add a manifest to your application that specifies the location.

An alternative in Python 2.6 or above is to use collections.namedtuple() -- it saves you writing any special methods:

from collections import namedtuple
MyThingBase = namedtuple("MyThingBase", ["name", "location"])
class MyThing(MyThingBase):
    def __new__(cls, name, location, length):
        obj = MyThingBase.__new__(cls, name, location)
        obj.length = length
        return obj

a = MyThing("a", "here", 10)
b = MyThing("a", "here", 20)
c = MyThing("c", "there", 10)
a == b
# True
hash(a) == hash(b)
# True
a == c
# False

It's a little unclear whether you're asking for opinions, eg. "it's common to do xxx" or an actual rule, so I'm going to lean in the direction of rules.

The examples you cite seem based upon the examples in the spec for the nav element. Remember that the spec keeps getting tweaked and the rules are sometimes convoluted, so I'd venture many people might tend to just do what's given rather than interpret. You're showing two separate examples with different behavior, so there's only so much you can read into it. Do either of those sites also have the opposing sub/nav situation, and if so how do they handle it?

Most importantly, though, there's nothing in the spec saying either is the way to do it. One of the goals with HTML5 was to be very clear[this for comparison] about semantics, requirements, etc. so the omission is worth noting. As far as I can see, the examples are independent of each other and equally valid within their own context of layout requirements, etc.

Having the nav's source position be conditional is kind of silly(another red flag). Just pick a method and go with it.

Set the resize property to both. Then you can change width and height like this:

.classname img{
  resize: both;
  width:50px;
  height:25px;
}

This is all you have to do:

In front.inc

global $name;
$name = 'james';

I agree with:

• the general amortized complexity of O(1)
• a bad hashCode() implementation could result to multiple collisions, which means that in the worst case every object goes to the same bucket, thus O(N) if each bucket is backed by a List.
• since Java 8, HashMap dynamically replaces the Nodes (linked list) used in each bucket with TreeNodes (red-black tree when a list gets bigger than 8 elements) resulting to a worst performance of O(logN).

But, this is not the full truth if we want to be 100% precise. The implementation of hashCode() and the type of key Object (immutable/cached or being a Collection) might also affect real time complexity in strict terms.

Let's assume the following three cases:

1. HashMap<Integer, V>
2. HashMap<String, V>
3. HashMap<List<E>, V>

Do they have the same complexity? Well, the amortised complexity of the 1st one is, as expected, O(1). But, for the rest, we also need to compute hashCode() of the lookup element, which means we might have to traverse arrays and lists in our algorithm.

Lets assume that the size of all of the above arrays/lists is k. Then, HashMap<String, V> and HashMap<List<E>, V> will have O(k) amortised complexity and similarly, O(k + logN) worst case in Java8.

*Note that using a String key is a more complex case, because it is immutable and Java caches the result of hashCode() in a private variable hash, so it's only computed once.

/** Cache the hash code for the string */
    private int hash; // Default to 0

But, the above is also having its own worst case, because Java's String.hashCode() implementation is checking if hash == 0 before computing hashCode. But hey, there are non-empty Strings that output a hashcode of zero, such as "f5a5a608", see here, in which case memoization might not be helpful.

On a MAC, you need to use nm *.o | c++filt, as there is no -C option in nm.

An alternative to GETDATE() is CURRENT_TIMESTAMP. Does the exact same thing.

This answer is totally unrelated to the OP's situation, and is a very unlikely scenario for anyone else too, but just in case it may help someone ...

In my case I was getting "Could not load file or assembly 'System.Windows.Forms, Version=4.0.0.0 ..." because I had disassembled and reassembled the program using ILDAsm.exe and ILAsm.exe from .Net Framework / SDK version 2. Switching to ILDAsm.exe and ILAsm.exe from .Net Framework / SDK version 4 fixed the problem.

(Strangely, even though doing what I did may seem like an obvious error, the resulting EXE file that didn't work did indicate that it targeted .Net 4 when examined with JetBrains dotPeek.)

Quite accidentally I bumped into this solution:

tableView.tableFooterView = UIView()
tableViewHeight.constant = tableView.contentSize.height

You need to set the footerView before getting the contentSize e.g. in viewDidLoad. Btw. setting the footeView lets you delete "unused" separators

check that entity is defined in hibernate.cfg.xml or not.

Alternatively, you can just exclude the dependency that you don't want. STAX is included in JDK 1.6, so if you're using 1.6 you can just exclude it entirely.

My example below is slightly wrong for you - you only need one of the two exclusions but I'm not quite sure which one. There are other versions of Stax floating about, in my example below I was importing A which imported B which imported C & D which each (through yet more transitive dependencies) imported different versions of Stax. So in my dependency on 'A', I excluded both versions of Stax.

<dependency>
  <groupId>a.group</groupId>
  <artifactId>a.artifact</artifactId>
  <version>a.version</version>
  <exclusions>
    <!--  STAX comes with Java 1.6 -->
    <exclusion>
      <artifactId>stax-api</artifactId>
      <groupId>javax.xml.stream</groupId>
    </exclusion>
    <exclusion>
      <artifactId>stax-api</artifactId>
      <groupId>stax</groupId>
    </exclusion>
  </exclusions>

Two options, either reference the new jars in your classpath or unpack all classes in the enclosing jars and re-jar the whole lot! As far as I know packaging jars within jars is not recommeneded and you'll forever have the class not found exception!

Your first mistake is thinking that ASCII encoding and Base64 encoding are interchangeable. They are not. They are used for different purposes.

• When you encode text in ASCII, you start with a text string and convert it to a sequence of bytes.
• When you encode data in Base64, you start with a sequence of bytes and convert it to a text string.

To understand why Base64 was necessary in the first place we need a little history of computing.

Computers communicate in binary - 0s and 1s - but people typically want to communicate with more rich forms data such as text or images. In order to transfer this data between computers it first has to be encoded into 0s and 1s, sent, then decoded again. To take text as an example - there are many different ways to perform this encoding. It would be much simpler if we could all agree on a single encoding, but sadly this is not the case.

Originally a lot of different encodings were created (e.g. Baudot code) which used a different number of bits per character until eventually ASCII became a standard with 7 bits per character. However most computers store binary data in bytes consisting of 8 bits each so ASCII is unsuitable for tranferring this type of data. Some systems would even wipe the most significant bit. Furthermore the difference in line ending encodings across systems mean that the ASCII character 10 and 13 were also sometimes modified.

To solve these problems Base64 encoding was introduced. This allows you to encode arbitrary bytes to bytes which are known to be safe to send without getting corrupted (ASCII alphanumeric characters and a couple of symbols). The disadvantage is that encoding the message using Base64 increases its length - every 3 bytes of data is encoded to 4 ASCII characters.

To send text reliably you can first encode to bytes using a text encoding of your choice (for example UTF-8) and then afterwards Base64 encode the resulting binary data into a text string that is safe to send encoded as ASCII. The receiver will have to reverse this process to recover the original message. This of course requires that the receiver knows which encodings were used, and this information often needs to be sent separately.

Historically it has been used to encode binary data in email messages where the email server might modify line-endings. A more modern example is the use of Base64 encoding to embed image data directly in HTML source code. Here it is necessary to encode the data to avoid characters like '<' and '>' being interpreted as tags.

Here is a working example:

I wish to send a text message with two lines:

Hello
world!

If I send it as ASCII (or UTF-8) it will look like this:

72 101 108 108 111 10 119 111 114 108 100 33

The byte 10 is corrupted in some systems so we can base 64 encode these bytes as a Base64 string:

SGVsbG8Kd29ybGQh

Which when encoded using ASCII looks like this:

83 71 86 115 98 71 56 75 100 50 57 121 98 71 81 104

All the bytes here are known safe bytes, so there is very little chance that any system will corrupt this message. I can send this instead of my original message and let the receiver reverse the process to recover the original message.

It's important to understand that there are two aspects to thread safety.

1. execution control, and
2. memory visibility

The first has to do with controlling when code executes (including the order in which instructions are executed) and whether it can execute concurrently, and the second to do with when the effects in memory of what has been done are visible to other threads. Because each CPU has several levels of cache between it and main memory, threads running on different CPUs or cores can see "memory" differently at any given moment in time because threads are permitted to obtain and work on private copies of main memory.

Using synchronized prevents any other thread from obtaining the monitor (or lock) for the same object, thereby preventing all code blocks protected by synchronization on the same object from executing concurrently. Synchronization also creates a "happens-before" memory barrier, causing a memory visibility constraint such that anything done up to the point some thread releases a lock appears to another thread subsequently acquiring the same lock to have happened before it acquired the lock. In practical terms, on current hardware, this typically causes flushing of the CPU caches when a monitor is acquired and writes to main memory when it is released, both of which are (relatively) expensive.

Using volatile, on the other hand, forces all accesses (read or write) to the volatile variable to occur to main memory, effectively keeping the volatile variable out of CPU caches. This can be useful for some actions where it is simply required that visibility of the variable be correct and order of accesses is not important. Using volatile also changes treatment of long and double to require accesses to them to be atomic; on some (older) hardware this might require locks, though not on modern 64 bit hardware. Under the new (JSR-133) memory model for Java 5+, the semantics of volatile have been strengthened to be almost as strong as synchronized with respect to memory visibility and instruction ordering (see http://www.cs.umd.edu/users/pugh/java/memoryModel/jsr-133-faq.html#volatile). For the purposes of visibility, each access to a volatile field acts like half a synchronization.

Under the new memory model, it is still true that volatile variables cannot be reordered with each other. The difference is that it is now no longer so easy to reorder normal field accesses around them. Writing to a volatile field has the same memory effect as a monitor release, and reading from a volatile field has the same memory effect as a monitor acquire. In effect, because the new memory model places stricter constraints on reordering of volatile field accesses with other field accesses, volatile or not, anything that was visible to thread A when it writes to volatile field f becomes visible to thread B when it reads f.

-- JSR 133 (Java Memory Model) FAQ

So, now both forms of memory barrier (under the current JMM) cause an instruction re-ordering barrier which prevents the compiler or run-time from re-ordering instructions across the barrier. In the old JMM, volatile did not prevent re-ordering. This can be important, because apart from memory barriers the only limitation imposed is that, for any particular thread, the net effect of the code is the same as it would be if the instructions were executed in precisely the order in which they appear in the source.

One use of volatile is for a shared but immutable object is recreated on the fly, with many other threads taking a reference to the object at a particular point in their execution cycle. One needs the other threads to begin using the recreated object once it is published, but does not need the additional overhead of full synchronization and it's attendant contention and cache flushing.

// Declaration
public class SharedLocation {
    static public SomeObject someObject=new SomeObject(); // default object
    }

// Publishing code
// Note: do not simply use SharedLocation.someObject.xxx(), since although
//       someObject will be internally consistent for xxx(), a subsequent 
//       call to yyy() might be inconsistent with xxx() if the object was 
//       replaced in between calls.
SharedLocation.someObject=new SomeObject(...); // new object is published

// Using code
private String getError() {
    SomeObject myCopy=SharedLocation.someObject; // gets current copy
    ...
    int cod=myCopy.getErrorCode();
    String txt=myCopy.getErrorText();
    return (cod+" - "+txt);
    }
// And so on, with myCopy always in a consistent state within and across calls
// Eventually we will return to the code that gets the current SomeObject.

Speaking to your read-update-write question, specifically. Consider the following unsafe code:

public void updateCounter() {
    if(counter==1000) { counter=0; }
    else              { counter++; }
    }

Now, with the updateCounter() method unsynchronized, two threads may enter it at the same time. Among the many permutations of what could happen, one is that thread-1 does the test for counter==1000 and finds it true and is then suspended. Then thread-2 does the same test and also sees it true and is suspended. Then thread-1 resumes and sets counter to 0. Then thread-2 resumes and again sets counter to 0 because it missed the update from thread-1. This can also happen even if thread switching does not occur as I have described, but simply because two different cached copies of counter were present in two different CPU cores and the threads each ran on a separate core. For that matter, one thread could have counter at one value and the other could have counter at some entirely different value just because of caching.

What's important in this example is that the variable counter was read from main memory into cache, updated in cache and only written back to main memory at some indeterminate point later when a memory barrier occurred or when the cache memory was needed for something else. Making the counter volatile is insufficient for thread-safety of this code, because the test for the maximum and the assignments are discrete operations, including the increment which is a set of non-atomic read+increment+write machine instructions, something like:

MOV EAX,counter
INC EAX
MOV counter,EAX

Volatile variables are useful only when all operations performed on them are "atomic", such as my example where a reference to a fully formed object is only read or written (and, indeed, typically it's only written from a single point). Another example would be a volatile array reference backing a copy-on-write list, provided the array was only read by first taking a local copy of the reference to it.

What is the underlying logic you want to implement? If, for instance, you want to test for the existence of a record to determine to insert or update then a better choice would be to use MERGE instead.

If you expect the record to exist most of the time, this is probably the most efficient way of doing things (although the CASE WHEN EXISTS solution is likely to be just as efficient):

begin
    select null into dummy
    from sales
    where sales_type = 'Accessories'
    and rownum = 1;

    --  do things here when record exists
    ....        

exception
    when no_data_found then
        -- do things here when record doesn't exists
        .....
end;

You only need the ROWNUM line if SALES_TYPE is not unique. There's no point in doing a count when all you want to know is whether at least one record exists.

Your formula should be of the form =IF(X2 >= 85,0.559,IF(X2 >= 80,0.327,IF(X2 >=75,0.255,0))). This simulates the ELSE-IF operand Excel lacks. Your formulas were using two conditions in each, but the second parameter of the IF formula is the value to use if the condition evaluates to true. You can't chain conditions in that manner.

Do keep in mind that the file.getContentType could also output application/octet-stream instead of the required application/vnd.openxmlformats-officedocument.spreadsheetml.sheet when you try to upload the file that is already open.

The problem is that you are using getSystemResourceAsStream. Use simply getResourceAsStream. System resources load from the system classloader, which is almost certainly not the class loader that your jar is loaded into when run as a webapp.

It works in Eclipse because when launching an application, the system classloader is configured with your jar as part of its classpath. (E.g. java -jar my.jar will load my.jar in the system class loader.) This is not the case with web applications - application servers use complex class loading to isolate webapplications from each other and from the internals of the application server. For example, see the tomcat classloader how-to, and the diagram of the classloader hierarchy used.

EDIT: Normally, you would call getClass().getResourceAsStream() to retrieve a resource in the classpath, but as you are fetching the resource in a static initializer, you will need to explicitly name a class that is in the classloader you want to load from. The simplest approach is to use the class containing the static initializer, e.g.

[public] class MyClass {
  static
  {
    ...
    props.load(MyClass.class.getResourceAsStream("/someProps.properties"));
  }
}

We can add the parent pom as a dependency with type pom and make exclusion on that. Because anyhow parent pom is downloaded. This worked for me

<dependency>
  <groupId>com.abc.boot</groupId>
  <artifactId>abc-boot-starter-parent</artifactId>
  <version>2.1.5.RELEASE</version>
  <type>pom</type>
  <exclusions>

      <artifactId>gson</artifactId>
    </exclusion>
  </exclusions>   
</dependency>

import os
current_file_path=os.path.dirname(os.path.realpath('__file__'))

What this means is that you are trying to print out/output a value which is at least partially uninitialized. Can you narrow it down so that you know exactly what value that is? After that, trace through your code to see where it is being initialized. Chances are, you will see that it is not being fully initialized.

If you need more help, posting the relevant sections of source code might allow someone to offer more guidance.

EDIT

I see you've found the problem. Note that valgrind watches for Conditional jump or move based on unitialized variables. What that means is that it will only give out a warning if the execution of the program is altered due to the uninitialized value (ie. the program takes a different branch in an if statement, for example). Since the actual arithmetic did not involve a conditional jump or move, valgrind did not warn you of that. Instead, it propagated the "uninitialized" status to the result of the statement that used it.

It may seem counterintuitive that it does not warn you immediately, but as mark4o pointed out, it does this because uninitialized values get used in C all the time (examples: padding in structures, the realloc() call, etc.) so those warnings would not be very useful due to the false positive frequency.

I was having a very similar problem. I was getting inconsistent height() values when I refreshed my page. (It wasn't my variable causing the problem, it was the actual height value.)

I noticed that in the head of my page I called my scripts first, then my css file. I switched so that the css file is linked first, then the script files and that seems to have fixed the problem so far.

Hope that helps.

To delete null and also empty entries Try this

  foreach (var column in drEntitity.Columns.Cast<DataColumn>().ToArray())
            {
                if (drEntitity.AsEnumerable().All(dr => dr.IsNull(column) | string.IsNullOrEmpty( dr[column].ToString())))
                    drEntitity.Columns.Remove(column);
            }

Static libraries do not link with other static libraries. The only way to do this is to use your librarian/archiver tool (for example ar on Linux) to create a single new static library by concatenating the multiple libraries.

Edit: In response to your update, the only way I know to select only the symbols that are required is to manually create the library from the subset of the .o files that contain them. This is difficult, time consuming and error prone. I'm not aware of any tools to help do this (not to say they don't exist), but it would make quite an interesting project to produce one.

When the argument -Xss doesn't do the job try deleting the temporary files from:

c:\Users\{user}\AppData\Local\Temp\.

This did the trick for me.

Go through project properties -> Reference Paths

Then add folder with DLL's

http://robert.ocallahan.org/2011/11/latency-of-html5-sounds.html

http://people.mozilla.org/~roc/audio-latency-repeating.html

Works OK in Firefox and Chrome for me.

To stop a sound that you started, do var sound = document.getElementById("shot").cloneNode(true); sound.play(); and later sound.pause();

Right click the project and give maven build,maven clean,maven generate resource and maven install.The jar file will automatically generate.

As a rather old and rusty C programmer who never quite made it fully to C++ because other things came along and is now hacking along getting to grips with Arduino my view is simple.

#define is a compiler pre processor directive and should be used as such, for conditional compilation etc.. E.g. where low level code needs to define some possible alternative data structures for portability to specif hardware. It can produce inconsistent results depending on the order your modules are compiled and linked. If you need something to be global in scope then define it properly as such.

const and (static const) should always be used to name static values or strings. They are typed and safe and the debugger can work fully with them.

enums have always confused me, so I have managed to avoid them.

You could try running the "mvn site" command and see what transitive dependencies you have, and then resolve potential conflicts (by ommitting an implicit dependency somewhere). Just a guess (it's a bit difficult to know what the problem could be without seeing your pom info)...

As the transcript for SciPy told you, SciPy isn't really supposed to work on Win64:

Warning: Windows 64 bits support is experimental, and only available for
testing. You are advised not to use it for production.

So I would suggest to install the 32-bit version of Python, and stop attempting to build SciPy yourself. If you still want to try anyway, you first need to compile BLAS and LAPACK, as PiotrLegnica says. See the transcript for the places where it was looking for compiled versions of these libraries.

Update: This only works for the local copy of the repository (the "client"). Please see others' comments below.

With a recent version of git (Feb 2014), the correct procedure would be:

git remote set-head $REMOTE_NAME $BRANCH

So for example, switching the head on remote origin to branch develop would be:

git remote set-head origin develop

You can resize using style and width to resize the textbox. Here is the code for it.

<!DOCTYPE html>_x000D_
<html lang="en">_x000D_
<head>_x000D_
    <meta charset="UTF-8">_x000D_
_x000D_
</head>_x000D_
<body>_x000D_
<div align="center">_x000D_
_x000D_
    <form method="post">_x000D_
          <div class="w3-row w3-section">_x000D_
            <div class="w3-rest" align = "center">_x000D_
                <input name="lastName" type="text" id="myInput" style="width: 50%">_x000D_
            </div>_x000D_
        </div>_x000D_
    </form>_x000D_
</div>_x000D_
</body>_x000D_
</html>

Use align to center the textbox.

32-bit JVMs which expect to have a single large chunk of memory and use raw pointers cannot use more than 4 Gb (since that is the 32 bit limit which also applies to pointers). This includes Sun and - I'm pretty sure - also IBM implementations. I do not know if e.g. JRockit or others have a large memory option with their 32-bit implementations.

If you expect to be hitting this limit you should strongly consider starting a parallel track validating a 64-bit JVM for your production environment so you have that ready for when the 32-bit environment breaks down. Otherwise you will have to do that work under pressure, which is never nice.

Edit 2014-05-15: Oracle FAQ:

The maximum theoretical heap limit for the 32-bit JVM is 4G. Due to various additional constraints such as available swap, kernel address space usage, memory fragmentation, and VM overhead, in practice the limit can be much lower. On most modern 32-bit Windows systems the maximum heap size will range from 1.4G to 1.6G. On 32-bit Solaris kernels the address space is limited to 2G. On 64-bit operating systems running the 32-bit VM, the max heap size can be higher, approaching 4G on many Solaris systems.

(http://www.oracle.com/technetwork/java/hotspotfaq-138619.html#gc_heap_32bit)

In a new Php 5.6, you can use ... operator instead of using func_get_args().

So, using this, you can get all the parameters you pass:

function manyVars(...$params) {
   var_dump($params);
}

I am using such code in config.php:

$lang = 'ru'; // this language will be used if there is no any lang information from useragent (for example, from command line, wget, etc...

if (!empty($_SERVER['HTTP_ACCEPT_LANGUAGE'])) $lang = substr($_SERVER['HTTP_ACCEPT_LANGUAGE'],0,2);
$tmp_value = $_COOKIE['language'];
if (!empty($tmp_value)) $lang = $tmp_value;
switch ($lang)
{
    case 'ru':
        $config['language'] = 'russian';
        setlocale(LC_ALL,'ru_RU.UTF-8'); 
        break;
        case 'uk':
        $config['language'] = 'ukrainian';
        setlocale(LC_ALL,'uk_UA.UTF-8'); 
                break;
        case 'foo':
        $config['language'] = 'foo';
        setlocale(LC_ALL,'foo_FOO.UTF-8'); 
                break;
        default:
        $config['language'] = 'english';
        setlocale(LC_ALL,'en_US.UTF-8'); 
        break;
}

.... and then i'm using usualy internal mechanizm of CI

o, almost forget! in views i using buttons, which seting cookie 'language' with language, prefered by user.

So, first this code try to detect "preffered language" setted in user`s useragent (browser). Then code try to read cookie 'language'. And finaly - switch sets language for CI-application

in the folder where the build.xml resides run command only -

if you want to use report in asp.net then use .rdl if you want to use /view in report builder / report server then use .rdlc just by converting format manually it works

I'd suggest that it is better practice to use String.format(). The main reason is that String.format() can be more easily localised with text loaded from resource files whereas concatenation can't be localised without producing a new executable with different code for each language.

If you plan on your app being localisable you should also get into the habit of specifying argument positions for your format tokens as well:

"Hello %1$s the time is %2$t"

This can then be localised and have the name and time tokens swapped without requiring a recompile of the executable to account for the different ordering. With argument positions you can also re-use the same argument without passing it into the function twice:

String.format("Hello %1$s, your name is %1$s and the time is %2$t", name, time)

it should vary with the architecture because it represents the size of any object. So on a 32-bit system size_t will likely be at least 32-bits wide. On a 64-bit system it will likely be at least 64-bit wide.

This is may have 2 reasons

1.I found the connection string error in my web.config file i had changed the connection string and its working.

2. Connection string is proper then check with the control panel>services> SQL Server Browser > start or not

Like in other answers, start your span attributes with this:

display:inline-block;  

Now you can use padding more than width:

padding-left:6%;
padding-right:6%;

When you use padding, your color expands to both side (right and left), not just right (like in widht).

For a VBScript / WMI one-liner that retrieves the actuals bits number (32 or 64) of the OS or the Hardware, take a look at http://csi-windows.com/toolkit/csi-getosbits

If you need fixed size types, use types like uint32_t (unsigned integer 32 bits) defined in stdint.h. They are specified in C99.

for example:

Rake::Task["db:migrate"].invoke

Try the fat-jar extension. It will include all external jars inside the jar.

Your UITableViewDelegate should implement tableView:heightForRowAtIndexPath:

Objective-C

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
    return [indexPath row] * 20;
}

Swift 5

func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
    return indexPath.row * 20
}

You will probably want to use NSString's sizeWithFont:constrainedToSize:lineBreakMode: method to calculate your row height rather than just performing some silly math on the indexPath :)

Your first example which uses Enumerable.Repeat:

private string Tabs(uint numTabs)
{
    IEnumerable<string> tabs = Enumerable.Repeat(
                                 "\t", (int) numTabs);
    return (numTabs > 0) ? 
            tabs.Aggregate((sum, next) => sum + next) : ""; 
} 

can be rewritten more compactly with String.Concat:

private string Tabs(uint numTabs)
{       
    return String.Concat(Enumerable.Repeat("\t", (int) numTabs));
}

jQuery has a method to check if something is a function

if ($.isFunction($.fn.dateJS)) {
    //your code using the plugin
}

API reference: https://api.jquery.com/jQuery.isFunction/

For the ones using Angular:

angular.isElement

https://docs.angularjs.org/api/ng/function/angular.isElement

I know this is an older question, but I saw it and I thought you might be interested in an alternative version than letting your view handle retrieving the data it needs to do it's job.

An easier way in my opinion would be to override the OnActionExecuting method. You are passed the ActionExecutingContext that contains the ActionDescriptor member which you can use to obtain the information you are looking for, which is the ActionName and you can also reach the ControllerDescriptor and it contains the ControllerName.

protected override void OnActionExecuting(ActionExecutingContext filterContext)
{
    ActionDescriptor actionDescriptor = filterContext.ActionDescriptor;
    string actionName = actionDescriptor.ActionName;
    string controllerName = actionDescriptor.ControllerDescriptor.ControllerName;
    // Now that you have the values, set them somewhere and pass them down with your ViewModel
    // This will keep your view cleaner and the controller will take care of everything that the view needs to do it's job.
}

Hope this helps. If anything, at least it will show an alternative for anybody else that comes by your question.

yes, it was introduced in 1993.

for further reference: Boolean Datatype

SELECT FIELD FROM TABLE
ORDER BY 
  isnumeric(FIELD) desc, 
  CASE ISNUMERIC(test) 
    WHEN 1 THEN CAST(CAST(test AS MONEY) AS INT)
    ELSE NULL 
  END,
  FIELD

As per this link you need to cast to MONEY then INT to avoid ordering '$' as a number.

To add to Silfheed's answer, which was useful, I needed to patch multiple methods of the object in question. I found it more elegant to do it this way:

Given the following function to test, located in module.a_function.to_test.py:

from some_other.module import SomeOtherClass

def add_results():
    my_object = SomeOtherClass('some_contextual_parameters')
    result_a = my_object.method_a()
    result_b = my_object.method_b()
    
    return result_a + result_b

To test this function (or class method, it doesn't matter), one can patch multiple methods of the class SomeOtherClass by using patch.object() in combination with sys.modules:

@patch.object(sys.modules['module.a_function.to_test'], 'SomeOtherClass')
def test__should_add_results(self, mocked_other_class):
  mocked_other_class().method_a.return_value = 4
  mocked_other_class().method_b.return_value = 7

  self.assertEqual(add_results(), 11)

This works no matter the number of methods of SomeOtherClass you need to patch, with independent results.

Also, using the same patching method, an actual instance of SomeOtherClass can be returned if need be:

@patch.object(sys.modules['module.a_function.to_test'], 'SomeOtherClass')
def test__should_add_results(self, mocked_other_class):
  other_class_instance = SomeOtherClass('some_controlled_parameters')
  mocked_other_class.return_value = other_class_instance

This worked for me. Put your cursor at the beginning of the word you want to replace, then

CtrlK, CtrlD, CtrlD ...

That should select as many instances of the word as you like, then you can just type the replacement.

My error was also related to not finding the required .so file by a service. I used LD_LIBRARY_PATH variable to priorities the path picked up by the linker to search the required lib.

I copied both service and .so file in a folder and fed it to LD_LIBRARY_PATH variable as

LD_LIBRARY_PATH=. ./service

being in the same folder I have given the above command and it worked.

I'm on Linux, but I guess you just use \r\n on Windows and it would also work

I'm using an MVC / MVA design pattern, with multiple types of "views". One type is a "GuiView", which is a Tk window. I pass a view reference to my window object which does things like link buttons back to view functions (which the adapter / controller class also calls).

In order to do that, the view object constructor needed to be completed prior to creating the window object. After creating and displaying the window, I wanted to do some initial tasks with the view automatically. At first I tried doing them post mainloop(), but that didn't work because mainloop() blocked!

As such, I created the window object and used tk.update() to draw it. Then, I kicked off my initial tasks, and finally started the mainloop.

import Tkinter as tk

class Window(tk.Frame):
    def __init__(self, master=None, view=None ):
        tk.Frame.__init__( self, master )
        self.view_ = view       
        """ Setup window linking it to the view... """

class GuiView( MyViewSuperClass ):

    def open( self ):
        self.tkRoot_ = tk.Tk()
        self.window_ = Window( master=None, view=self )
        self.window_.pack()
        self.refresh()
        self.onOpen()
        self.tkRoot_.mainloop()         

    def onOpen( self ):        
        """ Do some initial tasks... """

    def refresh( self ):        
        self.tkRoot_.update()

Well, PHP can do this easily.

It can be done with the PHP mail() function. Here's what a simple function would look like:

<?php     
$to_email = '[email protected]';
$subject = 'Testing PHP Mail';
$message = 'This mail is sent using the PHP mail function';
$headers = 'From: [email protected]';
mail($to_email,$subject,$message,$headers);
?>

This will send a background e-mail to the recipient specified in the $to_email.

The above example uses hard coded values in the source code for the email address and other details for simplicity.

Let’s assume you have to create a contact us form for users fill in the details and then submit.

1. Users can accidently or intentional inject code in the headers which can result in sending spam mail
2. To protect your system from such attacks, you can create a custom function that sanitizes and validates the values before the mail is sent.

Let’s create a custom function that validates and sanitizes the email address using the filter_var() built in function.

Here's an example code:

<?php 
function sanitize_my_email($field) {
    $field = filter_var($field, FILTER_SANITIZE_EMAIL);
    if (filter_var($field, FILTER_VALIDATE_EMAIL)) {
        return true;
    } else {
        return false;
    }
}
$to_email = '[email protected]';
$subject = 'Testing PHP Mail';
$message = 'This mail is sent using the PHP mail ';
$headers = 'From: [email protected]';
//check if the email address is invalid $secure_check
$secure_check = sanitize_my_email($to_email);
if ($secure_check == false) {
    echo "Invalid input";
} else { //send email 
    mail($to_email, $subject, $message, $headers);
    echo "This email is sent using PHP Mail";
}
?>

We will now let this be a separate PHP file, for example sendmail.php.

Then, will use this file on form submission, using the action attribute of the form, like:

<form action="sendmail.php" method="post">
   <input type="text" value="Your Name: ">
   <input type="password" value="Set Up A Passworrd">
   <input type="submit" value="Signup">
   <input type="reset" value="Reset Form">
</form>

Hope I could help

First point is- showing multiple popups is not desirable in terms of usability.

But you can achieve it by using multiple popup names

var newwindow;
function createPop(url, name)
{    
   newwindow=window.open(url,name,'width=560,height=340,toolbar=0,menubar=0,location=0');  
   if (window.focus) {newwindow.focus()}
}

Better approach will be showing both in a single page in two different iFrames or Divs.

Update:

So I will suggest to create a new tab in the test.aspx page to show the report, instead of replacing the image content and placing the pdf.

vimcryption

vim -x filename.txt

You will be asked for a passphrase, edit and save. Now whenever you open the file in vi again you will have to enter the password to view.

Due to this article is a good SEO site, so I suggest to use build-in function "mb_convert_variables" to solve this problem. It works with simple syntax.

mb_convert_variables('utf-8', 'original encode', array/object)

here is another solution

class MergeSort(object):
    def _merge(self,left, right):
        nl = len(left)
        nr = len(right)
        result = [0]*(nl+nr)
        i=0
        j=0
        for k in range(len(result)):
            if nl>i and nr>j:
                if left[i] <= right[j]:
                    result[k]=left[i]
                    i+=1
                else:
                    result[k]=right[j]
                    j+=1
            elif nl==i:
                result[k] = right[j]
                j+=1
            else: #nr>j:
                result[k] = left[i]
                i+=1
        return result

    def sort(self,arr):
        n = len(arr)
        if n<=1:
            return arr 
        left = self.sort(arr[:n/2])
        right = self.sort(arr[n/2:] )
        return self._merge(left, right)
def main():
    import random
    a= range(100000)
    random.shuffle(a)
    mr_clss = MergeSort()
    result = mr_clss.sort(a)
    #print result

if __name__ == '__main__':
    main()

and here is run time for list with 100000 elements:

real    0m1.073s
user    0m1.053s
sys         0m0.017s

Express version:

"dependencies": {
    "body-parser": "^1.19.0",
    "express": "^4.17.1"
  }

Optional parameter are very much handy, you can declare and use them easily using express:

app.get('/api/v1/tours/:cId/:pId/:batchNo?', (req, res)=>{
    console.log("category Id: "+req.params.cId);
    console.log("product ID: "+req.params.pId);
    if (req.params.batchNo){
        console.log("Batch No: "+req.params.batchNo);
    }
});

In the above code batchNo is optional. Express will count it optional because after in URL construction, I gave a '?' symbol after batchNo '/:batchNo?'

Now I can call with only categoryId and productId or with all three-parameter.

http://127.0.0.1:3000/api/v1/tours/5/10
//or
http://127.0.0.1:3000/api/v1/tours/5/10/8987

If you used read.table() (or one of it's ilk, e.g. read.csv()) then the easy fix is to change the call to:

read.table(file = "foo.txt", row.names = 1, ....)

where .... are the other arguments you needed/used. The row.names argument takes the column number of the data file from which to take the row names. It need not be the first column. See ?read.table for details/info.

If you already have the data in R and can't be bothered to re-read it, or it came from another route, just set the rownames attribute and remove the first variable from the object (assuming obj is your object)

rownames(obj) <- obj[, 1]  ## set rownames
obj <- obj[, -1]           ## remove the first variable

fwrite($handle, "<br>"."\r\n");

Add this under

$password = $_POST['password'].PHP_EOL;

I was trying to copy Gmail Login. When you click on "Email or phone" and type something on it the label translatesY(-38px) and scales(0.75).
What I did:-

<input type='email' class='email' placeholder=' ' />

Then In my CSS

input:not(:placeholder-shown){
//put my styles here and I got the expected results
}

If you try it and find any problem. Please share it.

This one here:

s = raw_input()
a=len(s)
for i in xrange(0, a):
    for j in xrange(0, a):
        if j >= i:
            if len(s[i:j+1]) > 0:
                sub_strings.append(s[i:j+1])

seems to be very inefficient and expensive for large strings.

Better do

for i in xrange(0, a):
    for j in xrange(i, a): # ensures that j >= i, no test required
        part = buffer(s, i, j+1-i) # don't duplicate data
        if len(part) > 0:
            sub_Strings.append(part)

A buffer object keeps a reference to the original string and start and length attributes. This way, no unnecessary duplication of data occurs.

A string of length l has l*l/2 sub strings of average length l/2, so the memory consumption would roughly be l*l*l/4. With a buffer, it is much smaller.

Note that buffer() only exists in 2.x. 3.x has memoryview(), which is utilized slightly different.

Even better would be to compute the indexes and cut out the substring on demand.

for ($i = 'A'; $i !=  $objPHPExcel->getActiveSheet()->getHighestColumn(); $i++) {
    $objPHPExcel->getActiveSheet()->getColumnDimension($i)->setAutoSize(TRUE);
}

Have you tried the Generate Scripts (Right click, tasks, generate scripts) option in SQL Management Studio? Does that produce what you mean by a "SQL File"?

I've made a jQuery plugin for working DRY:

$.fn.toggle2classes = function(class1, class2){
  if( !class1 || !class2 )
    return this;

  return this.each(function(){
    var $elm = $(this);

    if( $elm.hasClass(class1) || $elm.hasClass(class2) )
      $elm.toggleClass(class1 +' '+ class2);

    else
      $elm.addClass(class1);
  });
};

You can just try it here, copy and run this in the console and then try:

$('body').toggle2classes('a', 'b');

If letters are always in the beginning or at the end, you can simply just use trim...no regex needed

$string = trim($string, "a..zA..Z"); // this also take care of lowercase

"AR3,373.31" --> "3,373.31"
"12.322,11T" --> "12.322,11"
"12.322,11"  --> "12.322,11"

If you want to call JavaScript function in C#, this will help you:

public string functionname(arg)
{
    if (condition)
    {
        Page page = HttpContext.Current.CurrentHandler as Page;
        page.ClientScript.RegisterStartupScript(
            typeof(Page),
            "Test",
            "<script type='text/javascript'>functionname1(" + arg1 + ",'" + arg2 + "');</script>");
    }
}

Abstraction is the process where you "throw-away" unnecessary details from an entity you plan to capture/represent in your design and keep only the properties of the entity that are relevant to your domain.
Example: to represent car you would keep e.g. the model and price, current location and current speed and ignore color and number of seats etc.

Encapsulation is the "binding" of the properties and the operations that manipulate them in a single unit of abstraction (namely a class).
So the car would have accelarate stop that manipulate location and current speed etc.

While the other answers and the accepted one are correct and should be followed in real code, just for completeness and humor, you can try the fuckitpy ( https://github.com/ajalt/fuckitpy ) module.

Your code can be changed to the following:

@fuckitpy
def myfunc():
    do_smth1()
    do_smth2()

Then calling myfunc() would call do_smth2() even if there is an exception in do_smth1())

Note: Please do not try it in any real code, it is blasphemy

Use json in dataType and send like this:

    $.ajax({
        url: "your url which return json",
        type: "POST",
        crossDomain: true,
        data: data,
        dataType: "json",
        success:function(result){
            alert(JSON.stringify(result));
        },
        error:function(xhr,status,error){
            alert(status);
        }
    });

and put this lines in your server side file:

if PHP:

header('Access-Control-Allow-Origin: *');
header('Access-Control-Allow-Methods: POST');
header('Access-Control-Max-Age: 1000');

if java:

response.addHeader( "Access-Control-Allow-Origin", "*" ); 
response.addHeader( "Access-Control-Allow-Methods", "POST" ); 
response.addHeader( "Access-Control-Max-Age", "1000" );

In my case the image file had just been written to and needed to be flushed before opening, like so:

img_file.flush() 
img = Image.open(img_file.name))

A better way is to use the Stopwatch class:

using System.Diagnostics;
// ...

Stopwatch sw = new Stopwatch();

sw.Start();

// ...

sw.Stop();

Console.WriteLine("Elapsed={0}",sw.Elapsed);

CMake is more like a script language if comparing it with other ways to create Makefile (e.g. make or qmake). It is not very cool like Python, but still.

There are no such thing like a "proper way" if looking in various opensource projects how people include directories. But there are two ways to do it.

1. Crude include_directories will append a directory to the current project and all other descendant projects which you will append via a series of add_subdirectory commands. Sometimes people say that such approach is legacy.

2. A more elegant way is with target_include_directories. It allows to append a directory for a specific project/target without (maybe) unnecessary inheritance or clashing of various include directories. Also allow to perform even a subtle configuration and append one of the following markers for this command.

PRIVATE - use only for this specified build target

PUBLIC - use it for specified target and for targets which links with this project

INTERFACE -- use it only for targets which links with the current project

PS:

1. Both commands allow to mark a directory as SYSTEM to give a hint that it is not your business that specified directories will contain warnings.

2. A similar answer is with other pairs of commands target_compile_definitions/add_definitions, target_compile_options/CMAKE_C_FLAGS

Suppose: SqlConnection connectionObj = new SqlConnection()

for : connectionObj.ConnectionString -> use server name : (localdb)\\MSSQLLocalDB.

Note: Double back slash

for : App.config -> use server name : (localdb)\MSSQLLocalDB

Note: Single back slash

This took a while to get right. I had this issue when cross-compiling in Ubuntu for an ARM target. I solved it with:

PATH=$PATH:/ccpath/bin CC=ccname-gcc AR=ccname-ar LD=ccname-ld CPPFLAGS="-nostdinc -I/ccrootfs/usr/include ..." LDFLAGS=-L/ccrootfs/usr/lib ./autogen.sh --build=`config.guess` --host=armv5tejl-unknown-linux-gnueabihf

Notice CFLAGS is not used with autogen.sh/configure, using it gave me the error: "configure: error: C compiler cannot create executables". In the build environment I was using an autogen.sh script was provided, if you don't have an autogen.sh script substitute ./autogen.sh with ./configure in the command above. I ran config.guess on the target system to get the --host parameter.

After successfully running autogen.sh/configure, compile with:

PATH=$PATH:/ccpath/bin CC=ccname-gcc AR=ccname-ar LD=ccname-ld CPPFLAGS="-nostdinc -I/ccrootfs/usr/include ..." LDFLAGS=-L/ccrootfs/usr/lib CFLAGS="-march=... -mcpu=... etc." make

The CFLAGS I chose to use were: "-march=armv5te -fno-tree-vectorize -mthumb-interwork -mcpu=arm926ej-s". It will take a while to get all of the include directories set up correctly: you might want some includes pointing to your cross-compiler and some pointing to your root file system includes, and there will likely be some conflicts.

I'm sure this is not the perfect answer. And I am still seeing some include directories pointing to / and not /ccrootfs in the Makefiles. Would love to know how to correct this. Hope this helps someone.

I wanted to change the column value in a specific row. Thanks to above answers and after some serching able to come up with below,

var dataTable = $("#yourtableid");
var rowNumber = 0;  
var columnNumber= 2;   
dataTable[0].rows[rowNumber].cells[columnNumber].innerHTML = 'New Content';

You have some special words from CMAKE, take a look:

if(${CMAKE_SYSTEM_NAME} STREQUAL "Linux")
    // do something for Linux
else
    // do something for other OS

?These can help you:

You cannot scroll images continuously using the HTML marquee tag - it must have JavaScript added for the continuous scrolling functionality.

There is a JavaScript plugin called crawler.js available on the dynamic drive forum for achieving this functionality. This plugin was created by John Davenport Scheuer and has been modified over time to suit new browsers.

I have also implemented this plugin into my blog to document all the steps to use this plugin. Here is the sample code:

<head>
    <script src="http://code.jquery.com/jquery-latest.min.js" type="text/javascript"></script>
    <script src="assets/js/crawler.js" type="text/javascript" ></script>
</head>

<div id="mycrawler2" style="margin-top: -3px; " class="productswesupport">
    <img src="assets/images/products/ie.png" />
    <img src="assets/images/products/browser.png" />
    <img src="assets/images/products/chrome.png" />
    <img src="assets/images/products/safari.png" />
</div>

Here is the plugin configration:

marqueeInit({
    uniqueid: 'mycrawler2',
    style: {
    },
    inc: 5, //speed - pixel increment for each iteration of this marquee's movement
    mouse: 'cursor driven', //mouseover behavior ('pause' 'cursor driven' or false)
    moveatleast: 2,
    neutral: 150,
    savedirection: true,
    random: true
});

I have an application which relies heavily on Python and have kept up-to-date with python 2.7.x as new versions are released. Everthing has been fine until 2.7.11 when I got the same "No module named site" error. I've set PYTHONHOME to c:\Python27 and it's working. But the mystery remains why this is now needed when it wasn't with previous releases. And, if it is needed, why doesn't the installer set this var?

The problem is the tv.setText(text). The variable tv is probably null and you call the setText method on that null, which you can't. My guess that the problem is on the findViewById method, but it's not here, so I can't tell more, without the code.

Converting String to Character Array and then Converting Character array back to String

   //Givent String
   String given = "asdcbsdcagfsdbgdfanfghbsfdab";

   //Converting String to Character Array(It's an inbuild method of a String)
   char[] characterArray = given.toCharArray();
   //returns = [a, s, d, c, b, s, d, c, a, g, f, s, d, b, g, d, f, a, n, f, g, h, b, s, f, d, a, b]

//ONE WAY : Converting back Character array to String

  int length = Arrays.toString(characterArray).replaceAll("[, ]","").length();

  //First Way to get the string back
  Arrays.toString(characterArray).replaceAll("[, ]","").substring(1,length-1)
  //returns asdcbsdcagfsdbgdfanfghbsfdab
  or 
  // Second way to get the string back
  Arrays.toString(characterArray).replaceAll("[, ]","").replace("[","").replace("]",""))
 //returns asdcbsdcagfsdbgdfanfghbsfdab

//Second WAY : Converting back Character array to String

String.valueOf(characterArray);

//Third WAY : Converting back Character array to String

Arrays.stream(characterArray)
           .mapToObj(i -> (char)i)
           .collect(Collectors.joining());

Converting string to Character Array

Character[] charObjectArray =
                           givenString.chars().
                               mapToObj(c -> (char)c).
                               toArray(Character[]::new);

Converting char array to Character Array

 String givenString = "MyNameIsArpan";
char[] givenchararray = givenString.toCharArray();


     String.valueOf(givenchararray).chars().mapToObj(c -> 
                         (char)c).toArray(Character[]::new);

benefits of Converting char Array to Character Array you can use the Arrays.stream funtion to get the sub array

String subStringFromCharacterArray = 

              Arrays.stream(charObjectArray,2,6).
                          map(String::valueOf).
                          collect(Collectors.joining());

Here is what I did that worked great. I just imported an existing project under general instead of importing an android project.

Another alternative that seems faster than REGEXP on my computer is

SELECT * FROM myTable WHERE col1*0 != col1;

This will select all rows where col1 starts with a numeric value.

There is a technical aspect that should be emphasized, too. Say you need comparison behavior parameterization from a client class, and you are wondering whether to use Comparable or Comparator for a method like this:

class Pokemon {
    int healthPoints;
    int attackDamage;
    public void battle (Comparable<Pokemon> comparable, Pokemon opponent) {
        if (comparable.compareTo(opponent) > 0) { //comparable needs to, but cannot, access this.healthPoints for example
            System.out.println("battle won");
        } else {
            System.out.println("battle lost");
        }
    }
}

comparable would a lambda or an object, and there is no way for comparable to access the fields of this Pokemon. (In a lambda, this refers to the outer class instance in the lambda's scope, as defined in the program text.) So this doesn't fly, and we have to use a Comparator with two arguments.

You can use the JANSI library to render ANSI escape sequences in Windows.

In Windows 7, right-click on Computer -> Properties -> Advanced system settings; then in the Advanced tab, click Environment Variables... -> System variables -> New....

Give the new system variable the name JAVA_HOME and the value C:\Program Files\Java\jdk1.7.0_79 (depending on your JDK installation path it varies).

Then select the Path system variable and click Edit.... Keep the variable name as Path, and append C:\Program Files\Java\jdk1.7.0_79\bin; or %JAVA_HOME%\bin; (both mean the same) to the variable value.

Once you are done with above changes, try below steps. If you don't see similar results, restart the computer and try again. If it still doesn't work you may need to reinstall JDK.

Open a Windows command prompt (Windows key + R -> enter cmd -> OK), and check the following:

java -version

You will see something like this:

java version "1.7.0_79"
Java(TM) SE Runtime Environment (build 1.7.0_79-b15)
Java HotSpot(TM) 64-Bit Server VM (build 24.79-b02, mixed mode)

Then check the following:

javac -version

You will see something like this:

javac 1.7.0_79

My solutions in one of my own sites, with a table:

$.getJSON("sections/view_numbers_update.php", function(data) {
 $.each(data, function(index, objNumber) {
  $('#tr_' + objNumber.intID).find("td").eq(3).html(objNumber.datLastCalled);
  $('#tr_' + objNumber.intID).find("td").eq(4).html(objNumber.strStatus);
  $('#tr_' + objNumber.intID).find("td").eq(5).html(objNumber.intDuration);
  $('#tr_' + objNumber.intID).find("td").eq(6).html(objNumber.blnWasHuman);
 });
});

sections/view_numbers_update.php Returns something like:

[{"intID":"19","datLastCalled":"Thu, 10 Jan 13 08:52:20 +0000","strStatus":"Completed","intDuration":"0:04 secs","blnWasHuman":"Yes","datModified":1357807940},
{"intID":"22","datLastCalled":"Thu, 10 Jan 13 08:54:43 +0000","strStatus":"Completed","intDuration":"0:00 secs","blnWasHuman":"Yes","datModified":1357808079}]

HTML table:

<table id="table_numbers">
 <tr>
  <th>[...]</th>
  <th>[...]</th>
  <th>[...]</th>
  <th>Last Call</th>
  <th>Status</th>
  <th>Duration</th>
  <th>Human?</th>
  <th>[...]</th>
 </tr>
 <tr id="tr_123456">
  [...]
 </tr>
</table>

This essentially gives every row a unique id preceding with 'tr_' to allow for other numbered element ids, at server script time. The jQuery script then just gets this TR_[id] element, and fills the correct indexed cell with the json return.

The advantage is you could get the complete array from the DB, and either foreach($array as $record) to create the table html, OR (if there is an update request) you can die(json_encode($array)) before displaying the table, all in the same page, but same display code.

Just for completness, the "several variables" case is indeed possible, though not elegant at all. For example, for variables o, p, and q:

Optional.ofNullable( o ).orElseGet(()-> Optional.ofNullable( p ).orElseGet(()-> q ) )

Please note the use of orElseGet() attending to the case that o, p, and q are not variables but expressions either expensive or with undesired side-effects.

In the most general case coalesce(e[1],e[2],e[3],...,e[N])

coalesce-expression(i) ==  e[i]  when i = N
coalesce-expression(i) ==  Optional.ofNullable( e[i] ).orElseGet(()-> coalesce-expression(i+1) )  when i < N

This can generate expressions excessively long. However, if we are trying to move to a world without null, then v[i] are most probably already of type Optional<String>, as opposed to simply String. In this case,

result= o.orElse(p.orElse(q.get())) ;

or in the case of expressions:

result= o.orElseGet(()-> p.orElseGet(()-> q.get() ) ) ;

Furthermore, if you are also moving to a functional-declarative style, o, p, and q should be of type Supplier<String> like in:

Supplier<String> q= ()-> q-expr ;
Supplier<String> p= ()-> Optional.ofNullable(p-expr).orElseGet( q ) ;
Supplier<String> o= ()-> Optional.ofNullable(o-expr).orElseGet( p ) ;

And then the whole coalesce reduces simply to o.get().

For a more concrete example:

Supplier<Integer> hardcodedDefaultAge= ()-> 99 ;
Supplier<Integer> defaultAge= ()-> defaultAgeFromDatabase().orElseGet( hardcodedDefaultAge ) ;
Supplier<Integer> ageInStore= ()-> ageFromDatabase(memberId).orElseGet( defaultAge ) ;
Supplier<Integer> effectiveAge= ()-> ageFromInput().orElseGet( ageInStore ) ;

defaultAgeFromDatabase(), ageFromDatabase(), and ageFromInput() would already return Optional<Integer>, naturally.

And then the coalesce becomes effectiveAge.get() or simply effectiveAge if we are happy with a Supplier<Integer>.

IMHO, with Java 8 we will see more and more code structured like this, as it's extremely self-explainatory and efficient at the same time, especially in more complex cases.

I do miss a class Lazy<T> that invokes a Supplier<T> only one time, but lazily, as well as consistency in the definition of Optional<T> (i.e. Optional<T>-Optional<T> operators, or even Supplier<Optional<T>>).

In Java:

public boolean containsNumber(String string)
{
    return string.matches(".*\\d+.*");
}  

Start the DB server with the comandline option net_read_timeout / wait_timeout and a suitable value (in seconds) - for example: --net_read_timeout=100.

For reference see here and here.

In addition to others' answers :

static:: will be computed using runtime information.

That means you can't use static:: in a class property because properties values :

Must be able to be evaluated at compile time and must not depend on run-time information.

class Foo {
    public $name = static::class;

}

$Foo = new Foo;
echo $Foo->name; // Fatal error

Using self::

class Foo {
    public $name = self::class;

}
$Foo = new Foo;
echo $Foo->name; // Foo

Please note that the Fatal error comment in the code i made doesn't indicate where the error happened, the error happened earlier before the object was instantiated as @Grapestain mentioned in the comments

Sometimes you want to truncate to something calendar-based, like year or month. Here's an extension method that lets you choose any resolution.

public enum DateTimeResolution
{
    Year, Month, Day, Hour, Minute, Second, Millisecond, Tick
}

public static DateTime Truncate(this DateTime self, DateTimeResolution resolution = DateTimeResolution.Second)
{
    switch (resolution)
    {
        case DateTimeResolution.Year:
            return new DateTime(self.Year, 1, 1, 0, 0, 0, 0, self.Kind);
        case DateTimeResolution.Month:
            return new DateTime(self.Year, self.Month, 1, 0, 0, 0, self.Kind);
        case DateTimeResolution.Day:
            return new DateTime(self.Year, self.Month, self.Day, 0, 0, 0, self.Kind);
        case DateTimeResolution.Hour:
            return self.AddTicks(-(self.Ticks % TimeSpan.TicksPerHour));
        case DateTimeResolution.Minute:
            return self.AddTicks(-(self.Ticks % TimeSpan.TicksPerMinute));
        case DateTimeResolution.Second:
            return self.AddTicks(-(self.Ticks % TimeSpan.TicksPerSecond));
        case DateTimeResolution.Millisecond:
            return self.AddTicks(-(self.Ticks % TimeSpan.TicksPerMillisecond));
        case DateTimeResolution.Tick:
            return self.AddTicks(0);
        default:
            throw new ArgumentException("unrecognized resolution", "resolution");
    }
}

A convenient way would be boost's string algorithms library.

#include <boost/algorithm/string/classification.hpp> // Include boost::for is_any_of
#include <boost/algorithm/string/split.hpp> // Include for boost::split
// ...

std::vector<std::string> words;
std::string s;
boost::split(words, s, boost::is_any_of(", "), boost::token_compress_on);

Better would have been generate url like

app.dev/backend?type=surveys&id=2

and then use

var type=$location.search().type;
var id=$location.search().id;

and inject $location in controller.

This indicates the linux has delivered a SIGTERM to your process. This is usually at the request of some other process (via kill()) but could also be sent by your process to itself (using raise()). This signal requests an orderly shutdown of your process.

You can determine the sender by using an appropriate signal handler like:

#include <signal.h>
#include <stdio.h>
#include <stdlib.h>

void sigterm_handler(int signal, siginfo_t *info, void *_unused)
{
  fprintf(stderr, "Received SIGTERM from process with pid = %u\n",
      info->si_pid);
  exit(0);
}

int main (void)
{
  struct sigaction action = {
    .sa_handler = NULL,
    .sa_sigaction = sigterm_handler,
    .sa_mask = 0,
    .sa_flags = SA_SIGINFO,
    .sa_restorer = NULL
  };

  sigaction(SIGTERM, &action, NULL);
  sleep(60);

  return 0;
}

Notice that the signal handler also includes a call to exit(). It's also possible for your program to continue to execute by ignoring the signal, but this isn't recommended in general (if it's a user doing it there's a good chance it will be followed by a SIGKILL if your process doesn't exit, and you lost your opportunity to do any cleanup then).

ssl client side will throw such exception in below situation(I had tested), :

server is asked to authenticate client certificate, but the client provide a certificate which Extended Key Usage donot support client auth.

$scope.rtGo = function(){
            $window.sessionStorage.removeItem('message');
            $window.sessionStorage.removeItem('status');
        }

Your countLines(String filename) method throws IOException.

You can't use it in a member declaration. You'll need to perform the operation in a main(String[] args) method.

Your main(String[] args) method will get the IOException thrown to it by countLines and it will need to handle or declare it.

Try this to just throw the IOException from main

public class MyClass {
  private int lineCount;
  public static void main(String[] args) throws IOException {
    lineCount = LineCounter.countLines(sFileName);
  }
}

or this to handle it and wrap it in an unchecked IllegalArgumentException:

public class MyClass {
  private int lineCount;
  private String sFileName  = "myfile";
  public static void main(String[] args) throws IOException {
    try {
      lineCount = LineCounter.countLines(sFileName);
     } catch (IOException e) {
       throw new IllegalArgumentException("Unable to load " + sFileName, e);
     }
  }
}

It took me a while to understand what people meant by 'SERVER_NAME is more reliable'. I use a shared server and does not have access to virtual host directives. So, I use mod_rewrite in .htaccess to map different HTTP_HOSTs to different directories. In that case, it is HTTP_HOST that is meaningful.

The situation is similar if one uses name-based virtual hosts: the ServerName directive within a virtual host simply says which hostname will be mapped to this virtual host. The bottom line is that, in both cases, the hostname provided by the client during the request (HTTP_HOST), must be matched with a name within the server, which is itself mapped to a directory. Whether the mapping is done with virtual host directives or with htaccess mod_rewrite rules is secondary here. In these cases, HTTP_HOST will be the same as SERVER_NAME. I am glad that Apache is configured that way.

However, the situation is different with IP-based virtual hosts. In this case and only in this case, SERVER_NAME and HTTP_HOST can be different, because now the client selects the server by the IP, not by the name. Indeed, there might be special configurations where this is important.

So, starting from now, I will use SERVER_NAME, just in case my code is ported in these special configurations.

One way: (implementing 'considered equal' for http://tools.ietf.org/html/rfc6902#section-4.6)

This way allows associative arrays whose members are ordered differently - e.g. they'd be considered equal in every language but php :)

// recursive ksort
function rksort($a) {
  if (!is_array($a)) {
    return $a;
  }
  foreach (array_keys($a) as $key) {
    $a[$key] = ksort($a[$key]);
  }
  // SORT_STRING seems required, as otherwise
  // numeric indices (e.g. "0") aren't sorted.
  ksort($a, SORT_STRING);
  return $a;
}


// Per http://tools.ietf.org/html/rfc6902#section-4.6
function considered_equal($a1, $a2) {
  return json_encode(rksort($a1)) === json_encode(rksort($a2));
}

This solution worked for me:

<body onload="setTimeout(function() { document.myform.submit() }, 5000)">
   <form action=TripRecorder name="myform">
      <textarea id="result1"  name="res1" value="str1" cols="20" rows="1" ></textarea> <br> <br/>
      <textarea id="result2" name="res2" value="str2" cols="20" rows="1" ></textarea>
   </form>
</body>

^CTR

or

^CTR.*

edit:

To be more clear: ^CTR will match start of line and those chars. If all you want to do is match for a line itself (and already have the line to use), then that is all you really need. But if this is the case, you may be better off using a prefab substr() type function. I don't know, what language are you are using. But if you are trying to match and grab the line, you will need something like .* or .*$ or whatever, depending on what language/regex function you are using.

In my opinion [] and {} are the most pythonic and readable ways to create empty lists/dicts.

Be wary of set()'s though, for example:

this_set = {5}
some_other_set = {}

Can be confusing. The first creates a set with one element, the second creates an empty dict and not a set.

For instance you can use

update tablename set datetimefield='19980223 14:23:05'
update tablename set datetimefield='02/23/1998 14:23:05'
update tablename set datetimefield='1998-12-23 14:23:05'
update tablename set datetimefield='23 February 1998 14:23:05'
update tablename set datetimefield='1998-02-23T14:23:05'

You need to be careful of day/month order since this will be language dependent when the year is not specified first. If you specify the year first then there is no problem; date order will always be year-month-day.

If you want to use a specific transform function, then all you need to do is include that function in the value. For example:

$('.user-text').css('transform', 'scale(' + ui.value + ')');

Secondly, browser support is getting better, but you'll probably still need to use vendor prefixes like so:

$('.user-text').css({
  '-webkit-transform' : 'scale(' + ui.value + ')',
  '-moz-transform'    : 'scale(' + ui.value + ')',
  '-ms-transform'     : 'scale(' + ui.value + ')',
  '-o-transform'      : 'scale(' + ui.value + ')',
  'transform'         : 'scale(' + ui.value + ')'
});

Yes, you can set this on the inventory/host level.

^{With an already accepted answer present, I think this is a better answer to the question on how to handle this on the inventory level. I consider this more secure by isolating this insecure setting to the hosts required for this (e.g. test systems, local development machines).}

What you can do at the inventory level is add

ansible_ssh_common_args='-o StrictHostKeyChecking=no'

or

ansible_ssh_extra_args='-o StrictHostKeyChecking=no'

to your host definition (see Ansible Behavioral Inventory Parameters).

This will work provided you use the ssh connection type, not paramiko or something else).

For example, a Vagrant host definition would look like…

vagrant ansible_port=2222 ansible_host=127.0.0.1 ansible_ssh_common_args='-o StrictHostKeyChecking=no'

or

vagrant ansible_port=2222 ansible_host=127.0.0.1 ansible_ssh_extra_args='-o StrictHostKeyChecking=no'

Running Ansible will then be successful without changing any environment variable.

$ ansible vagrant -i <path/to/hosts/file> -m ping
vagrant | SUCCESS => {
    "changed": false, 
    "ping": "pong"
}

In case you want to do this for a group of hosts, here's a suggestion to make it a supplemental group var for an existing group like this:

[mytestsystems]
test[01:99].example.tld

[insecuressh:children]
mytestsystems

[insecuressh:vars]
ansible_ssh_common_args='-o StrictHostKeyChecking=no'

It's quite feasible to generate labeled icons server-side, if you have some programming skills. You'll need the GD library at the server, in addition to PHP. Been working well for me for several years now, but admittedly tricky to get the icon images in synch.

I do that via AJAX by sending the few parameters to define the blank icon and the text and color as well as bgcolor to be applied. Here's my PHP:

header("Content-type: image/png");
//$img_url = "./icons/gen_icon5.php?blank=7&text=BB";

function do_icon ($icon, $text, $color) {
$im = imagecreatefrompng($icon);
imageAlphaBlending($im, true);
imageSaveAlpha($im, true);

$len = strlen($text);
$p1 = ($len <= 2)? 1:2 ;
$p2 = ($len <= 2)? 3:2 ;
$px = (imagesx($im) - 7 * $len) / 2 + $p1;
$font = 'arial.ttf';
$contrast = ($color)? imagecolorallocate($im, 255, 255, 255): imagecolorallocate($im, 0, 0, 0); // white on dark?

imagestring($im, $p2, $px, 3, $text, $contrast);    // imagestring  ( $image, $font, $x, $y, $string, $color)

imagepng($im);
imagedestroy($im);
}
$icons =   array("black.png", "blue.png", "green.png", "red.png", "white.png", "yellow.png", "gray.png", "lt_blue.png", "orange.png");      // 1/9/09
$light =   array( TRUE,         TRUE,       FALSE,       FALSE,     FALSE,      FALSE,      FALSE,          FALSE,      FALSE);     // white text?

$the_icon = $icons[$_GET['blank']];             // 0 thru 8 (note: total 9)
$the_text = substr($_GET['text'], 0, 3);        // enforce 2-char limit
do_icon ($the_icon, $the_text,$light[$_GET['blank']] ); 

It's invoked client-side via something like the following: var image_file = "./our_icons/gen_icon.php?blank=" + escape(icons[color]) + "&text=" + iconStr;

Update for Express 4.4.1

Middleware of the following is removed from Express.

• bodyParser
• json
• urlencoded
• multipart

When you use the middleware directly like you did in express 3.0. You will get the following error:

Error: Most middleware (like urlencoded) is no longer bundled with Express and 
must be installed separately.

In order to utilize those middleware, now you need to do npm for each middleware separately.

Since bodyParser is marked as deprecated, so I recommend the following way using json, urlencode and multipart parser like formidable, connect-multiparty. (Multipart middleware is deprecated as well).

Also remember, just defining urlencode + json, the form data will not be parsed and req.body will be undefined. You need to define a middleware handle the multipart request.

var urlencode = require('urlencode');
var json = require('json-middleware');
var multipart = require('connect-multiparty');
var multipartMiddleware = multipart();

app.use(json);
app.use(urlencode);
app.use('/url/that/accepts/form-data', multipartMiddleware);

I know it's late but hope it will help someone else...

This is my code: It takes two by two hex representations contained in String and add those into byte array. It works perfectly for me.

public byte[] stringToByteArray (String s) {
    byte[] byteArray = new byte[s.length()/2];
    String[] strBytes = new String[s.length()/2];
    int k = 0;
    for (int i = 0; i < s.length(); i=i+2) {
        int j = i+2;
        strBytes[k] = s.substring(i,j);
        byteArray[k] = (byte)Integer.parseInt(strBytes[k], 16);
        k++;
    }
    return byteArray;
}

You can use the following function to extract data

CREATE FUNCTION [dbo].[SplitString]
(    
    @RowData NVARCHAR(MAX),
    @Delimeter NVARCHAR(MAX)
)
RETURNS @RtnValue TABLE 
(
    ID INT IDENTITY(1,1),
    Data NVARCHAR(MAX)
) 
AS
BEGIN 
    DECLARE @Iterator INT
    SET @Iterator = 1

    DECLARE @FoundIndex INT
    SET @FoundIndex = CHARINDEX(@Delimeter,@RowData)

    WHILE (@FoundIndex>0)
    BEGIN
        INSERT INTO @RtnValue (data)
        SELECT 
            Data = LTRIM(RTRIM(SUBSTRING(@RowData, 1, @FoundIndex - 1)))

        SET @RowData = SUBSTRING(@RowData,
                @FoundIndex + DATALENGTH(@Delimeter) / 2,
                LEN(@RowData))

        SET @Iterator = @Iterator + 1
        SET @FoundIndex = CHARINDEX(@Delimeter, @RowData)
    END

    INSERT INTO @RtnValue (Data)
    SELECT Data = LTRIM(RTRIM(@RowData))

    RETURN
END

Use something like

ALTER TABLE T2
ADD CONSTRAINT fk_employee
FOREIGN KEY (employeeID)
REFERENCES T1 (employeeID)
ON DELETE CASCADE;

Fill in the correct column names and you should be set. As mark_s correctly stated, if you have already a foreign key constraint in place, you maybe need to delete the old one first and then create the new one.

????: Quote: Usually the progress bar is either themed or honors the user's color preferences. So for changing the color you either need to turn off visual styles and set ForeColor or draw the control yourself.

As for the continuous style instead of blocks you can set the Style property:

pBar.Style = ProgressBarStyle.Continuous;

ProgressBarStyle.Continuous versus Blocks is useless with VistualStyles enabled...

Block(s) will only work with visual styles disabled ... which renders all of this a moot point (with regards to custom progress color) With vistual styles disabled ... the progress bar should be colored based on the forecolor.

I used a combination of William Daniel's answer (with visual styles enabled, so the ForeColor will not just be flat with no style) and Barry's answer (to custom text on the progress bar) from: How do I put text on ProgressBar?

Reading @ofavre's and @stanislav-bashkyrtsev's answers using broken GIT submodule references to create the GIT directories, I'm surprised that nobody has suggested yet this simple amendment of the idea to make the whole thing sane and safe:

Rather than hacking a fake submodule into GIT, just add an empty real one.

Enter: https://gitlab.com/empty-repo/empty.git

A GIT repository with exactly one commit:

commit e84d7b81f0033399e325b8037ed2b801a5c994e0
Author: Nobody <none>
Date: Thu Jan 1 00:00:00 1970 +0000

No message, no committed files.

Usage

To add an empty directory to you GIT repo:

git submodule add https://gitlab.com/empty-repo/empty.git path/to/dir

To convert all existing empty directories to submodules:

find . -type d -empty -delete -exec git submodule add -f https://gitlab.com/empty-repo/empty.git \{\} \;

Git will store the latest commit hash when creating the submodule reference, so you don't have to worry about me (or GitLab) using this to inject malicious files. Unfortunately I have not found any way to force which commit ID is used during checkout, so you'll have to manually check that the reference commit ID is e84d7b81f0033399e325b8037ed2b801a5c994e0 using git submodule status after adding the repo.

Still not a native solution, but the best we probably can have without somebody getting their hands really, really dirty in the GIT codebase.

Appendix: Recreating this commit

You should be able to recreate this exact commit using (in an empty directory):

# Initialize new GIT repository
git init

# Set author data (don't set it as part of the `git commit` command or your default data will be stored as “commit author”)
git config --local user.name "Nobody"
git config --local user.email "none"

# Set both the commit and the author date to the start of the Unix epoch (this cannot be done using `git commit` directly)
export GIT_AUTHOR_DATE="Thu Jan 1 00:00:00 1970 +0000"
export GIT_COMMITTER_DATE="Thu Jan 1 00:00:00 1970 +0000"

# Add root commit
git commit --allow-empty --allow-empty-message --no-edit

Creating reproducible GIT commits is surprisingly hard…

• Structure and class are user defied data types

• By default, structure is a public whereas class is private

• Class implements the principal of encapsulation

• Objects of a class are created on the heap memory

• Class is used for re usability whereas structure is used for grouping the data in the same structure

• Structure data members cannot be initialized directly but they can be assigned by the outside the structure

• Class data members can be initialized directly by the parameter less constructor and assigned by the parameterized constructor

__construct() is the method name for the constructor. The constructor is called on an object after it has been created, and is a good place to put initialisation code, etc.

class Person {

    public function __construct() {
        // Code called for each new Person we create
    }

}

$person = new Person();

A constructor can accept parameters in the normal manner, which are passed when the object is created, e.g.

class Person {

    public $name = '';

    public function __construct( $name ) {
        $this->name = $name;
    }

}

$person = new Person( "Joe" );
echo $person->name;

Unlike some other languages (e.g. Java), PHP doesn't support overloading the constructor (that is, having multiple constructors which accept different parameters). You can achieve this effect using static methods.

Note: I retrieved this from the log of the (at time of this writing) accepted answer.

Wget currently only supports x-www-form-urlencoded data. --post-file is not for transmitting files as form attachments, it expects data with the form: key=value&otherkey=example.

--post-data and --post-file work the same way: the only difference is that --post-data allows you to specify the data in the command line, while --post-file allows you to specify the path of the file that contain the data to send.

Here's the documentation:

 --post-data=string
       --post-file=file
           Use POST as the method for all HTTP requests and send the specified data
           in the request body.  --post-data sends string as data, whereas
           --post-file sends the contents of file.  Other than that, they work in
           exactly the same way. In particular, they both expect content of the
           form "key1=value1&key2=value2", with percent-encoding for special
           characters; the only difference is that one expects its content as a
           command-line parameter and the other accepts its content from a file. In
           particular, --post-file is not for transmitting files as form
           attachments: those must appear as "key=value" data (with appropriate
           percent-coding) just like everything else. Wget does not currently
           support "multipart/form-data" for transmitting POST data; only
           "application/x-www-form-urlencoded". Only one of --post-data and
           --post-file should be specified.

Regarding your authentication token, it should either be provided in the header, in the path of the url, or in the data itself. This must be indicated somewhere in the documentation of the service you use. In a POST request, as in a GET request, you must specify the data using keys and values. This way the server will be able to receive multiple information with specific names. It's similar with variables.

Hence, you can't just send a magic token to the server, you also need to specify the name of the key. If the key is "token", then it should be token=YOUR_TOKEN.

wget --post-data 'user=foo&password=bar' http://example.com/auth.php

Also, you should consider using curl if you can because it is easier to send files using it. There are many examples on the Internet for that.

Ordinary javascript cannot close windows willy-nilly. This is a security feature, introduced a while ago, to stop various malicious exploits and annoyances.

From the latest working spec for window.close():

The close() method on Window objects should, if all the following conditions are met, close the browsing context A:

• The corresponding browsing context A is script-closable.
• The browsing context of the incumbent script is familiar with the browsing context A.
• The browsing context of the incumbent script is allowed to navigate the browsing context A.

A browsing context is script-closable if it is an auxiliary browsing context that was created by a script (as opposed to by an action of the user), or if it is a browsing context whose session history contains only one Document.

This means, with one small exception, javascript must not be allowed to close a window that was not opened by that same javascript.

Chrome allows that exception -- which it doesn't apply to userscripts -- however Firefox does not. The Firefox implementation flat out states:

This method is only allowed to be called for windows that were opened by a script using the window.open method.

If you try to use window.close from a Greasemonkey / Tampermonkey / userscript you will get:
Firefox: The error message, "Scripts may not close windows that were not opened by script."
Chrome: just silently fails.

The long-term solution:

The best way to deal with this is to make a Chrome extension and/or Firefox add-on instead. These can reliably close the current window.

However, since the security risks, posed by window.close, are much less for a Greasemonkey/Tampermonkey script; Greasemonkey and Tampermonkey could reasonably provide this functionality in their API (essentially packaging the extension work for you).
Consider making a feature request.

The hacky workarounds:

Chrome is currently was vulnerable to the "self redirection" exploit. So code like this used to work in general:

open(location, '_self').close();

This is buggy behavior, IMO, and is now (as of roughly April 2015) mostly blocked. It will still work from injected code only if the tab is freshly opened and has no pages in the browsing history. So it's only useful in a very small set of circumstances.

However, a variation still works on Chrome (v43 & v44) plus Tampermonkey (v3.11 or later). Use an explicit @grant and plain window.close(). EG:

// ==UserScript==
// @name        window.close demo
// @include     http://YOUR_SERVER.COM/YOUR_PATH/*
// @grant       GM_addStyle
// ==/UserScript==

setTimeout (window.close, 5000);

Thanks to zanetu for the update. Note that this will not work if there is only one tab open. It only closes additional tabs.

Firefox is secure against that exploit. So, the only javascript way is to cripple the security settings, one browser at a time.

You can open up about:config and set
allow_scripts_to_close_windows to true.

If your script is for personal use, go ahead and do that. If you ask anyone else to turn that setting on, they would be smart, and justified, to decline with prejudice.

There currently is no equivalent setting for Chrome.

You can let PHP do a POST, but then your php will get the return, with all sorts of complications. I think the simplest would be to actually let the user do the POST.

So, kind-of what you suggested, you'll get indeed this part:

Customer fill detail in Page A, then in Page B we create another page show all the customer detail there, click a CONFIRM button then POST to Page C.

But you can actually do a javascript submit on page B, so there is no need for a click. Make it a "redirecting" page with a loading animation, and you're set.

UEFA or FIFA don't seem to provide any API to get the information you want. However, there are some third-party services which support that:

• OPTA - Both commercial and free. They have incredible database about matches. Whoscored.com currently uses it.

• Others: livescoreboards, xmlsoccer, ...

git format-patch --full-index --binary --stdout range... | git am -3

One big gotcha is that PHP is disabled in user home directories by default, so if you are testing from ~/public_html it doesn't work. Check /etc/apache2/mods-enabled/php5.conf

# Running PHP scripts in user directories is disabled by default
# 
# To re-enable PHP in user directories comment the following lines
# (from <IfModule ...> to </IfModule>.) Do NOT set it to On as it
# prevents .htaccess files from disabling it.
#<IfModule mod_userdir.c>
#    <Directory /home/*/public_html>
#        php_admin_flag engine Off
#    </Directory>
#</IfModule>

Other than that installing in Ubuntu is real easy, as all the stuff you used to have to put in httpd.conf is done automatically.

You can use mysql_real_escape_string. mysql_real_escape_string() does not escape % and _, so you should escape MySQL wildcards (% and _) separately.

I have used the below code in my existing project

<div class="form-group" [ngStyle]="{'border':isSubmitted && form_data.controls.first_name.errors?'1px solid red':'' }">

My shell script calls the sql file and executes it. The spool output had the SQL query at the beginning followed by the query result.

This did not resolve my problem:

set echo off

This resolved my problem:

set verify off

For me the basic oracle only was not installed. Please ensure you have oracle installed and then try checking host and port.

If you do not need to modify the substring, then you can use QStringRef. The QStringRef class is a read only wrapper around an existing QString that references a substring within the existing string. This gives much better performance than creating a new QString object to contain the sub-string. E.g.

QString myString("This is a string");
QStringRef subString(&myString, 5, 2); // subString contains "is"

If you do need to modify the substring, then left(), mid() and right() will do what you need...

QString myString("This is a string");
QString subString = myString.mid(5,2); // subString contains "is"
subString.append("n't"); // subString contains "isn't"

During explorative development, and to focus the SQL debugging logging on the specific method I want to check, I decorate that method with the following logger statements:

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import ch.qos.logback.classic.Level;

((ch.qos.logback.classic.Logger) LoggerFactory.getLogger("org.hibernate.SQL")).setLevel(Level.DEBUG);
entityManager.find(Customer.class, customerID);
((ch.qos.logback.classic.Logger) LoggerFactory.getLogger("org.hibernate.SQL")).setLevel(Level.INFO);

While the core of Git, the Git plumbing doesn't keep track of renames, the history you display with the Git log "porcelain" can detect them if you like.

For a given git log use the -M option:

git log -p -M

With a current version of Git.

This works for other commands like git diff as well.

There are options to make the comparisons more or less rigorous. If you rename a file without making significant changes to the file at the same time it makes it easier for Git log and friends to detect the rename. For this reason some people rename files in one commit and change them in another.

There's a cost in CPU use whenever you ask Git to find where files have been renamed, so whether you use it or not, and when, is up to you.

If you would like to always have your history reported with rename detection in a particular repository you can use:

git config diff.renames 1

Files moving from one directory to another is detected. Here's an example:

commit c3ee8dfb01e357eba1ab18003be1490a46325992
Author: John S. Gruber <[email protected]>
Date:   Wed Feb 22 22:20:19 2017 -0500

    test rename again

diff --git a/yyy/power.py b/zzz/power.py
similarity index 100%
rename from yyy/power.py
rename to zzz/power.py

commit ae181377154eca800832087500c258a20c95d1c3
Author: John S. Gruber <[email protected]>
Date:   Wed Feb 22 22:19:17 2017 -0500

    rename test

diff --git a/power.py b/yyy/power.py
similarity index 100%
rename from power.py
rename to yyy/power.py

Please note that this works whenever you are using diff, not just with git log. For example:

$ git diff HEAD c3ee8df
diff --git a/power.py b/zzz/power.py
similarity index 100%
rename from power.py
rename to zzz/power.py

As a trial I made a small change in one file in a feature branch and committed it and then in the master branch I renamed the file, committed, and then made a small change in another part of the file and committed that. When I went to feature branch and merged from master the merge renamed the file and merged the changes. Here's the output from the merge:

 $ git merge -v master
 Auto-merging single
 Merge made by the 'recursive' strategy.
  one => single | 4 ++++
  1 file changed, 4 insertions(+)
  rename one => single (67%)

The result was a working directory with the file renamed and both text changes made. So it's possible for Git to do the right thing despite the fact that it doesn't explicitly track renames.

_{This is an late answer to an old question so the other answers may have been correct for the Git version at the time.}

To convert integer to char only 0 to 9 will be converted. As we know 0's ASCII value is 48 so we have to add its value to the integer value to convert in into the desired character hence

int i=5;
char c = i+'0';

Mutable default arguments don't generally do what you want. Instead, try this:

class Node:
     def __init__(self, wordList=None, adjacencyList=None):
        if wordList is None:
            self.wordList = []
        else:
             self.wordList = wordList 
        if adjacencyList is None:
            self.adjacencyList = []
        else:
             self.adjacencyList = adjacencyList 

Because python 3 print() function allows end="" definition, that satisfies the majority of issues.

In my case, I wanted to PrettyPrint and was frustrated that this module wasn't similarly updated. So i made it do what i wanted:

from pprint import PrettyPrinter

class CommaEndingPrettyPrinter(PrettyPrinter):
    def pprint(self, object):
        self._format(object, self._stream, 0, 0, {}, 0)
        # this is where to tell it what you want instead of the default "\n"
        self._stream.write(",\n")

def comma_ending_prettyprint(object, stream=None, indent=1, width=80, depth=None):
    """Pretty-print a Python object to a stream [default is sys.stdout] with a comma at the end."""
    printer = CommaEndingPrettyPrinter(
        stream=stream, indent=indent, width=width, depth=depth)
    printer.pprint(object)

Now, when I do:

comma_ending_prettyprint(row, stream=outfile)

I get what I wanted (substitute what you want -- Your Mileage May Vary)

For my case, it turns out the gitlab was runnign in docker, and has port mapping 4022/22.

Thus I have to edit ~/.ssh/config to specify the port via Port 4022, e.g:

Host gitlab-local
    Hostname        192.168.1.101
    User git
    Port 4022
    IdentityFile    ~/.ssh/id_rsa.pub
    # LogLevel DEBUG3

open your /etc/paths file, put /usr/local/bin on top of /usr/bin

$ sudo vi /etc/paths
/usr/local/bin
/usr/local/sbin
/usr/bin
/bin
/usr/sbin
/sbin

and Restart the terminal, @mmel

If you only want to read the first 999,999 (non-header) rows:

read_csv(..., nrows=999999)

If you only want to read rows 1,000,000 ... 1,999,999

read_csv(..., skiprows=1000000, nrows=999999)

nrows : int, default None Number of rows of file to read. Useful for reading pieces of large files*

skiprows : list-like or integer Row numbers to skip (0-indexed) or number of rows to skip (int) at the start of the file

and for large files, you'll probably also want to use chunksize:

chunksize : int, default None Return TextFileReader object for iteration

pandas.io.parsers.read_csv documentation

Use a for loop instead of .forEach()

var myObj = [{"a": "1","b": null},{"a": "2","b": 5}]
var result = false

for(var call of myObj) {
    console.log(call)
    
    var a = call['a'], b = call['b']
     
    if(a == null || b == null) {
        result = false
        break
    }
}

Like I use on PHP and JavaScript:

<input type="hidden" id="CatId" value="<?php echo $categoryId; ?>">

Update the JavaScript:

var categoryId = document.getElementById('CatId').value;

Just declare it outside class definition.

If your namespace's name is X, you will be able to access the enum's values by X.card_suit

If you have not defined a namespace for this enum, just call them by card_suit.Clubs etc.

According to the ALTER DATABASE SET documentation, there is still a possibility that after setting a database to SINGLE_USER mode you won't be able to access that database:

Before you set the database to SINGLE_USER, verify the AUTO_UPDATE_STATISTICS_ASYNC option is set to OFF. When set to ON, the background thread used to update statistics takes a connection against the database, and you will be unable to access the database in single-user mode.

So, a complete script to drop the database with existing connections may look like this:

DECLARE @dbId int
DECLARE @isStatAsyncOn bit
DECLARE @jobId int
DECLARE @sqlString nvarchar(500)

SELECT @dbId = database_id,
       @isStatAsyncOn = is_auto_update_stats_async_on
FROM sys.databases
WHERE name = 'db_name'

IF @isStatAsyncOn = 1
BEGIN
    ALTER DATABASE [db_name] SET  AUTO_UPDATE_STATISTICS_ASYNC OFF

    -- kill running jobs
    DECLARE jobsCursor CURSOR FOR
    SELECT job_id
    FROM sys.dm_exec_background_job_queue
    WHERE database_id = @dbId

    OPEN jobsCursor

    FETCH NEXT FROM jobsCursor INTO @jobId
    WHILE @@FETCH_STATUS = 0
    BEGIN
        set @sqlString = 'KILL STATS JOB ' + STR(@jobId)
        EXECUTE sp_executesql @sqlString
        FETCH NEXT FROM jobsCursor INTO @jobId
    END

    CLOSE jobsCursor
    DEALLOCATE jobsCursor
END

ALTER DATABASE [db_name] SET  SINGLE_USER WITH ROLLBACK IMMEDIATE

DROP DATABASE [db_name]

If I do code in pyQt I use QT sockets/signals paradigm, same is for django

If I'm doing async I/O I use native select module

If I'm usign a SAX python parser I'm using event API provided by SAX. So it looks like I'm victim of underlying API :-)

Maybe you should ask yourself what do you expect from event framework/module. My personal preference is to use Socket/Signal paradigm from QT. more info about that can be found here

You can also provide a negative number as an argument to the round method to round to the nearest multiple of 10, 100 and so on.

# Round to the nearest multiple of 10. 
12.3453.round(-1)       # Output: 10

# Round to the nearest multiple of 100. 
124.3453.round(-2)      # Output: 100

You can implement Drag&Drop in WinForms and WPF.

• WinForm (Drag from app window)

You should add mousemove event:

private void YourElementControl_MouseMove(object sender, MouseEventArgs e)

    {
     ...
         if (e.Button == MouseButtons.Left)
         {
                 DoDragDrop(new DataObject(DataFormats.FileDrop, new string[] { PathToFirstFile,PathToTheNextOne }), DragDropEffects.Move);
         }
     ...
    }

• WinForm (Drag to app window)

You should add DragDrop event:

private void YourElementControl_DragDrop(object sender, DragEventArgs e)

    {
       ...
       foreach (string path in (string[])e.Data.GetData(DataFormats.FileDrop))
            {
                File.Copy(path, DirPath + Path.GetFileName(path));
            }
       ...
    }

Source with full code.

I'm definitely not a Ruby expert, but I'll give it a shot:

$ irb 
system "echo Hi"
Hi
=> true

You should also be able to do things like:

cmd = 'ls'
system(cmd)

if (str.toLowerCase().indexOf("yes") >= 0)

Or,

if (/yes/i.test(str))

I defined a median function for a list of numbers as

def median(numbers):
    return (sorted(numbers)[int(round((len(numbers) - 1) / 2.0))] + sorted(numbers)[int(round((len(numbers) - 1) // 2.0))]) / 2.0

Make sure you have .NET 4.6.2 Developer Pack for VS installed and then pull in System.ValueTuple package from NuGet.

You can use any on process for dynamic path on command prompt

Process p = Runtime.getRuntime().exec("cmd.exe /c start dir ");
Process p = Runtime.getRuntime().exec("cmd.exe /c start cd \"E:\\rakhee\\Obligation Extractions\" && dir");
Process p = Runtime.getRuntime().exec("cmd.exe /c start cd \"E:\\oxyzen-workspace\\BrightleafDesktop\\Obligation Extractions\" && dir");

public static class PropertyInfoExtensions
{
    public static TValue GetAttributValue<TAttribute, TValue>(this PropertyInfo prop, Func<TAttribute, TValue> value) where TAttribute : Attribute
    {
        var att = prop.GetCustomAttributes(
            typeof(TAttribute), true
            ).FirstOrDefault() as TAttribute;
        if (att != null)
        {
            return value(att);
        }
        return default(TValue);
    }
}

Usage:

 //get class properties with attribute [AuthorAttribute]
        var props = typeof(Book).GetProperties().Where(prop => Attribute.IsDefined(prop, typeof(AuthorAttribute)));
            foreach (var prop in props)
            {
               string value = prop.GetAttributValue((AuthorAttribute a) => a.Name);
            }

or:

 //get class properties with attribute [AuthorAttribute]
        var props = typeof(Book).GetProperties().Where(prop => Attribute.IsDefined(prop, typeof(AuthorAttribute)));
        IList<string> values = props.Select(prop => prop.GetAttributValue((AuthorAttribute a) => a.Name)).Where(attr => attr != null).ToList();

You were looking for help on installations with pip. You can find it with the following command:

pip install --help

Running pip install -e /path/to/package installs the package in a way, that you can edit the package, and when a new import call looks for it, it will import the edited package code. This can be very useful for package development.

The !== opererator tests whether values are not equal or not the same type. i.e.

var x = 5;
var y = '5';
var 1 = y !== x; // true
var 2 = y != x; // false

Using jQuery data() to store data

I guess hiding elements doesn't work cross-browser(2012), I have'nt tested it myself.

Or you can just use this method in case you don't have StringUtils on hand:

public static String abbreviateString(String input, int maxLength) {
    if (input.length() <= maxLength) 
        return input;
    else 
        return input.substring(0, maxLength-2) + "..";
}

from datetime import datetime
datetime.now().strftime('%Y-%m-%d %H:%M:%S')

For this example, the output will be like this: '2013-09-18 11:16:32'

Here is the list of strftime directives.

add an ALIAS on the subquery,

SELECT  COUNT(made_only_recharge) AS made_only_recharge
FROM    
    (
        SELECT DISTINCT (identifiant) AS made_only_recharge
        FROM cdr_data
        WHERE CALLEDNUMBER = '0130'
        EXCEPT
        SELECT DISTINCT (identifiant) AS made_only_recharge
        FROM cdr_data
        WHERE CALLEDNUMBER != '0130'
    ) AS derivedTable                           -- <<== HERE

As describe here

1. Open your php.ini file (look for it)

2. Add the following line of code on the top of the file:

   date.timezone = "US/Central"

3. Verify the changes by going to phpinfo.php

from datetime import datetime as dt

then use this in your code:

cur.execute('INSERT INTO my_table (dt_col) VALUES (%s)', (dt.now(),))

Try this to create the user:

CREATE USER 'user'@'hostname';

Try this to give it access to the database dbTest:

GRANT ALL PRIVILEGES ON dbTest.* To 'user'@'hostname' IDENTIFIED BY 'password';

If you are running the code/site accessing MySQL on the same machine, hostname would be localhost.

Now, the break down.

GRANT - This is the command used to create users and grant rights to databases, tables, etc.

ALL PRIVILEGES - This tells it the user will have all standard privileges. This does not include the privilege to use the GRANT command however.

dbtest.* - This instructions MySQL to apply these rights for use in the entire dbtest database. You can replace the * with specific table names or store routines if you wish.

TO 'user'@'hostname' - 'user' is the username of the user account you are creating. Note: You must have the single quotes in there. 'hostname' tells MySQL what hosts the user can connect from. If you only want it from the same machine, use localhost

IDENTIFIED BY 'password' - As you would have guessed, this sets the password for that user.

If I understood it right you are doing an XMLHttpRequest to a different domain than your page is on. So the browser is blocking it as it usually allows a request in the same origin for security reasons. You need to do something different when you want to do a cross-domain request. A tutorial about how to achieve that is Using CORS.

When you are using postman they are not restricted by this policy. Quoted from Cross-Origin XMLHttpRequest:

Regular web pages can use the XMLHttpRequest object to send and receive data from remote servers, but they're limited by the same origin policy. Extensions aren't so limited. An extension can talk to remote servers outside of its origin, as long as it first requests cross-origin permissions.

The user-agent should be specified as a field in the header.

Here is a list of HTTP header fields, and you'd probably be interested in request-specific fields, which includes User-Agent.

If you're using requests v2.13 and newer

The simplest way to do what you want is to create a dictionary and specify your headers directly, like so:

import requests

url = 'SOME URL'

headers = {
    'User-Agent': 'My User Agent 1.0',
    'From': '[email protected]'  # This is another valid field
}

response = requests.get(url, headers=headers)

If you're using requests v2.12.x and older

Older versions of requests clobbered default headers, so you'd want to do the following to preserve default headers and then add your own to them.

import requests

url = 'SOME URL'

# Get a copy of the default headers that requests would use
headers = requests.utils.default_headers()

# Update the headers with your custom ones
# You don't have to worry about case-sensitivity with
# the dictionary keys, because default_headers uses a custom
# CaseInsensitiveDict implementation within requests' source code.
headers.update(
    {
        'User-Agent': 'My User Agent 1.0',
    }
)

response = requests.get(url, headers=headers)

1. Framework agnostic: Servlet downloading file as attachment

<!-- with JS -->
<a href="javascript:window.location='downloadServlet?param1=value1'">
    download
</a>

<!-- without JS -->
<a href="downloadServlet?param1=value1" >download</a>

2. Struts2 Framework: Action downloading file as attachment

<!-- with JS -->
<a href="javascript:window.location='downloadAction.action?param1=value1'">
    download
</a>

<!-- without JS -->
<a href="downloadAction.action?param1=value1" >download</a>

It would be better to use <s:a> tag pointing with OGNL to an URL created with <s:url> tag:

<!-- without JS, with Struts tags: THE RIGHT WAY -->    
<s:url action="downloadAction.action" var="url">
    <s:param name="param1">value1</s:param>
</s:ulr>
<s:a href="%{url}" >download</s:a>

In the above cases, you need to write the Content-Disposition header to the response, specifying that the file needs to be downloaded (attachment) and not opened by the browser (inline). You need to specify the Content Type too, and you may want to add the file name and length (to help the browser drawing a realistic progressbar).

For example, when downloading a ZIP:

response.setContentType("application/zip");
response.addHeader("Content-Disposition", 
                   "attachment; filename=\"name of my file.zip\"");
response.setHeader("Content-Length", myFile.length()); // or myByte[].length...

With Struts2 (unless you are using the Action as a Servlet, an hack for direct streaming, for example), you don't need to directly write anything to the response; simply using the Stream result type and configuring it in struts.xml will work: EXAMPLE

<result name="success" type="stream">
   <param name="contentType">application/zip</param>
   <param name="contentDisposition">attachment;filename="${fileName}"</param>
   <param name="contentLength">${fileLength}</param>
</result>

3. Framework agnostic (/ Struts2 framework): Servlet(/Action) opening file inside the browser

If you want to open the file inside the browser, instead of downloading it, the Content-disposition must be set to inline, but the target can't be the current window location; you must target a new window created by javascript, an <iframe> in the page, or a new window created on-the-fly with the "discussed" target="_blank":

<!-- From a parent page into an IFrame without javascript -->   
<a href="downloadServlet?param1=value1" target="iFrameName">
    download
</a>

<!-- In a new window without javascript --> 
<a href="downloadServlet?param1=value1" target="_blank">
    download
</a>

<!-- In a new window with javascript -->    
<a href="javascript:window.open('downloadServlet?param1=value1');" >
    download
</a>

One mistake what i did was not including "implements OnClickListener" in the main class declaration. This is a sample code to clearly illustrate the use of switch case during on click. The code changes background colour as per the button pressed. Hope this helps.

The System.DateTime class has a property called Now, which:

Gets a DateTime object that is set to the current date and time on this computer, expressed as the local time.

You can set the Text property of your label to the current time like this (where myLabel is the name of your label):

myLabel.Text = DateTime.Now.ToString();

None of the answer is working for me.

As the error message is package corrupt , I will have to run

1. adb uninstall <package name>
2. Run app again / use adb install

SELECT users.id, DATE_FORMAT(users.signup_date, '%Y-%m-%d') 
FROM users 
WHERE DATE(signup_date) = CURDATE()

On my case, just to be safe regarding scrolling, I added the window.scroll to the equation:

var element = document.getElementById('myElement');
var topPos = element.getBoundingClientRect().top + window.scrollY;
var leftPos = element.getBoundingClientRect().left + window.scrollX;

That allows me to get the real relative position of element on document, even if it has been scrolled.

col_Names=["Sequence", "Start", "End", "Coverage"]
my_CSV_File= pd.read_csv("yourCSVFile.csv",names=col_Names)

having done this, just check it with[well obviously I know, u know that. But still...

my_CSV_File.head()

Hope it helps ... Cheers

Imagine you are showing someone how to code something with a bunch of "random" numbers. By using numpy seed they can use the same seed number and get the same set of "random" numbers.

So it's not exactly random because an algorithm spits out the numbers but it looks like a randomly generated bunch.

For those getting this error in a Jenkins pipeline, it can be fixed by using an SSH Agent plugin. Then wrap your git commands in something like this:

sshagent(['my-ssh-key']) {
    git remote set-url origin [email protected]:username/reponame.git
    sh 'git push origin branch_name'
}

If you want the conversion to always succeed, probably the best way to convert the string would be to consider "1" as true and anything else as false (as Kevin does). If you wanted the conversion to fail if anything other than "1" or "0" is returned, then the following would suffice (you could put it in a helper method):

if (returnValue == "1")
{
    return true;
}
else if (returnValue == "0")
{
    return false;
}
else
{
    throw new FormatException("The string is not a recognized as a valid boolean value.");
}

Good luck! PT

Try Like this.

tv1.setText("  " + Integer.toString(X[i]) + "\n" + "+" + " " + Integer.toString(Y[i]));

File.AppendAllText does not know about the stream you have opened, so will internally try to open the file again. Because your stream is blocking access to the file, File.AppendAllText will fail, throwing the exception you see.

I suggest you used str.Write or str.WriteLine instead, as you already do elsewhere in your code.

Your file is created but contains nothing because the exception is thrown before str.Flush() and str.Close() are called.

Use this

&TEXT(E5;"0.00")&

There is a very simple way in which you can do this. It involves injecting a javascript code to a label control from code behind. here is sample code:

<head runat="server"> 
    <title>Calling javascript function from code behind example</title> 
        <script type="text/javascript"> 
            function showDialogue() { 
                alert("this dialogue has been invoked through codebehind."); 
            } 
        </script> 
</head>

..........

lblJavaScript.Text = "<script type='text/javascript'>showDialogue();</script>";

It looks like you're passing in Null for every argument except for PropertyValueID and DropDownOptionID, right? I don't think any of your IF statements will fire if only these two values are not-null. In short, I think you have a logic error.

Other than that, I would suggest two things...

First, instead of testing for NULL, use this kind syntax on your if statements (it's safer)...

    ELSE IF ISNULL(@UnitValue, 0) != 0 AND ISNULL(@UnitOfMeasureID, 0) = 0

Second, add a meaningful PRINT statement before each UPDATE. That way, when you run the sproc in MSSQL, you can look at the messages and see how far it's actually getting.

Say your string is:

let str = `word1
word2;word3,word4,word5;word7
word8,word9;word10`;

You want to split the string by the following delimiters:

• Colon
• Semicolon
• New line

You could split the string like this:

let rawElements = str.split(new RegExp('[,;\n]', 'g'));

Finally, you may need to trim the elements in the array:

let elements = rawElements.map(element => element.trim());

print type(variable_name)

I also highly recommend the IPython interactive interpreter when dealing with questions like this. It lets you type variable_name? and will return a whole list of information about the object including the type and the doc string for the type.

e.g.

In [9]: var = 123

In [10]: var?
Type:       int
Base Class: <type 'int'>
String Form:    123
Namespace:  Interactive
Docstring:
    int(x[, base]) -> integer

Convert a string or number to an integer, if possible. A floating point argument will be truncated towards zero (this does not include a string representation of a floating point number!) When converting a string, use the optional base. It is an error to supply a base when converting a non-string. If the argument is outside the integer range a long object will be returned instead.

I ended up here looking to delete my node_modules folders before doing a backup of my work in progress using rsync. A key requirements is that the node_modules folder can be nested, so you need the -prune option.

First I ran this to visually verify the folders to be deleted:

find -type d -name node_modules -prune

Then I ran this to delete them all:

find -type d -name node_modules -prune -exec rm -rf {} \;

In Three.js R66, this is what I use (CoffeeScript version):

  rotWorldMatrix.makeRotationAxis axis.normalize(), radians
  rotWorldMatrix.multiply this.matrix
  this.matrix = rotWorldMatrix
  this.rotation.setFromRotationMatrix this.matrix

Its not a good idea to pass Context objects around. This often will lead to memory leaks. My suggestion is that you don't do it. I have made numerous Android apps without having to pass context to non-activity classes in the app. A better idea would be to get the resources you need access to while your in the Activity or Fragment, and hold onto it in another class. You can then use that class in any other classes in your app to access the resources, without having to pass around Context objects.

Use:

/*/ITEM[starts-with(REVENUE_YEAR,'2552')]/REGION

Note: Unless your host language can't handle element instance as result, do not use text nodes specially in mixed content data model. Do not start expressions with // operator when the schema is well known.

I would say the most elegant way is this:

<div class="toggle"></div>
<div class="content">...</div>

then css:

.toggle{
 display:inline-block;
height:48px;
width:48px;  background:url("http://icons.iconarchive.com/icons/pixelmixer/basic/48/plus-icon.png");
}
.toggle.expanded{
  background:url("http://cdn2.iconfinder.com/data/icons/onebit/PNG/onebit_32.png");
}

and js:

$(document).ready(function(){
  var $content = $(".content").hide();
  $(".toggle").on("click", function(e){
    $(this).toggleClass("expanded");
    $content.slideToggle();
  });
});

NOT STRICTLY RELATED TO TYPESCRIPT

Just to add to all the above answers, we can also use the shorthand syntax

var result = uemail || '';

This will give you the email if uemail variable has some value and it will simply return an empty string if uemail variable is undefined.

This gives a nice syntax for handling undefined variables and also provide a way to use a default value in case the variable is undefined.

I would like to add a new column, 'e', to the existing data frame and do not change anything in the data frame. (The series always got the same length as a dataframe.)

I assume that the index values in e match those in df1.

The easiest way to initiate a new column named e, and assign it the values from your series e:

df['e'] = e.values

assign (Pandas 0.16.0+)

As of Pandas 0.16.0, you can also use assign, which assigns new columns to a DataFrame and returns a new object (a copy) with all the original columns in addition to the new ones.

df1 = df1.assign(e=e.values)

As per this example (which also includes the source code of the assign function), you can also include more than one column:

df = pd.DataFrame({'a': [1, 2], 'b': [3, 4]})
>>> df.assign(mean_a=df.a.mean(), mean_b=df.b.mean())
   a  b  mean_a  mean_b
0  1  3     1.5     3.5
1  2  4     1.5     3.5

In context with your example:

The description of this new feature when it was first introduced can be found here.

While this question is old, the answers aren't proper. Context menus have their own events on DataGridView. There is an event for row context menu and cell context menu.

The reason for which these answers aren't proper is they do not account for different operation schemes. Accessibility options, remote connections, or Metro/Mono/Web/WPF porting might not work and keyboard shortcuts will down right fail (Shift+F10 or Context Menu key).

Cell selection on right mouse click has to be handled manually. Showing the context menu does not need to be handled as this is handled by the UI.

This completely mimics the approach used by Microsoft Excel. If a cell is part of a selected range, the cell selection doesn't change and neither does CurrentCell. If it isn't, the old range is cleared and the cell is selected and becomes CurrentCell.

If you are unclear on this, CurrentCell is where the keyboard has focus when you press the arrow keys. Selected is whether it is part of SelectedCells. The context menu will show on right click as handled by the UI.

private void dgvAccount_CellMouseDown(object sender, DataGridViewCellMouseEventArgs e)
{
    if (e.ColumnIndex != -1 && e.RowIndex != -1 && e.Button == System.Windows.Forms.MouseButtons.Right)
    {
        DataGridViewCell c = (sender as DataGridView)[e.ColumnIndex, e.RowIndex];
        if (!c.Selected)
        {
            c.DataGridView.ClearSelection();
            c.DataGridView.CurrentCell = c;
            c.Selected = true;
        }
    }
}

Keyboard shortcuts do not show the context menu by default, so we have to add them in.

private void dgvAccount_KeyDown(object sender, KeyEventArgs e)
{
    if ((e.KeyCode == Keys.F10 && e.Shift) || e.KeyCode == Keys.Apps)
    {
        e.SuppressKeyPress = true;
        DataGridViewCell currentCell = (sender as DataGridView).CurrentCell;
        if (currentCell != null)
        {
            ContextMenuStrip cms = currentCell.ContextMenuStrip;
            if (cms != null)
            {
                Rectangle r = currentCell.DataGridView.GetCellDisplayRectangle(currentCell.ColumnIndex, currentCell.RowIndex, false);
                Point p = new Point(r.X + r.Width, r.Y + r.Height);
                cms.Show(currentCell.DataGridView, p);
            }
        }
    }
}

I've reworked this code to work statically, so you can copy and paste them into any event.

The key is to use CellContextMenuStripNeeded since this will give you the context menu.

Here's an example using CellContextMenuStripNeeded where you can specify which context menu to show if you want to have different ones per row.

In this context MultiSelect is True and SelectionMode is FullRowSelect. This is just for the example and not a limitation.

private void dgvAccount_CellContextMenuStripNeeded(object sender, DataGridViewCellContextMenuStripNeededEventArgs e)
{
    DataGridView dgv = (DataGridView)sender;

    if (e.RowIndex == -1 || e.ColumnIndex == -1)
        return;
    bool isPayment = true;
    bool isCharge = true;
    foreach (DataGridViewRow row in dgv.SelectedRows)
    {
        if ((string)row.Cells["P/C"].Value == "C")
            isPayment = false;
        else if ((string)row.Cells["P/C"].Value == "P")
            isCharge = false;
    }
    if (isPayment)
        e.ContextMenuStrip = cmsAccountPayment;
    else if (isCharge)
        e.ContextMenuStrip = cmsAccountCharge;
}

private void cmsAccountPayment_Opening(object sender, CancelEventArgs e)
{
    int itemCount = dgvAccount.SelectedRows.Count;
    string voidPaymentText = "&Void Payment"; // to be localized
    if (itemCount > 1)
        voidPaymentText = "&Void Payments"; // to be localized
    if (tsmiVoidPayment.Text != voidPaymentText) // avoid possible flicker
        tsmiVoidPayment.Text = voidPaymentText;
}

private void cmsAccountCharge_Opening(object sender, CancelEventArgs e)
{
    int itemCount = dgvAccount.SelectedRows.Count;
    string deleteChargeText = "&Delete Charge"; //to be localized
    if (itemCount > 1)
        deleteChargeText = "&Delete Charge"; //to be localized
    if (tsmiDeleteCharge.Text != deleteChargeText) // avoid possible flicker
        tsmiDeleteCharge.Text = deleteChargeText;
}

private void tsmiVoidPayment_Click(object sender, EventArgs e)
{
    int paymentCount = dgvAccount.SelectedRows.Count;
    if (paymentCount == 0)
        return;

    bool voidPayments = false;
    string confirmText = "Are you sure you would like to void this payment?"; // to be localized
    if (paymentCount > 1)
        confirmText = "Are you sure you would like to void these payments?"; // to be localized
    voidPayments = (MessageBox.Show(
                    confirmText,
                    "Confirm", // to be localized
                    MessageBoxButtons.YesNo,
                    MessageBoxIcon.Warning,
                    MessageBoxDefaultButton.Button2
                   ) == DialogResult.Yes);
    if (voidPayments)
    {
        // SQLTransaction Start
        foreach (DataGridViewRow row in dgvAccount.SelectedRows)
        {
            //do Work    
        }
    }
}

private void tsmiDeleteCharge_Click(object sender, EventArgs e)
{
    int chargeCount = dgvAccount.SelectedRows.Count;
    if (chargeCount == 0)
        return;

    bool deleteCharges = false;
    string confirmText = "Are you sure you would like to delete this charge?"; // to be localized
    if (chargeCount > 1)
        confirmText = "Are you sure you would like to delete these charges?"; // to be localized
    deleteCharges = (MessageBox.Show(
                    confirmText,
                    "Confirm", // to be localized
                    MessageBoxButtons.YesNo,
                    MessageBoxIcon.Warning,
                    MessageBoxDefaultButton.Button2
                   ) == DialogResult.Yes);
    if (deleteCharges)
    {
        // SQLTransaction Start
        foreach (DataGridViewRow row in dgvAccount.SelectedRows)
        {
            //do Work    
        }
    }
}

suppose supply_master is a table, and

SQL>desc supply_master;


SQL>Name
 SUPPLIER_NO    
 SUPPLIER_NAME
 ADDRESS1       
 ADDRESS2       
 CITY           
 STATE          
 PINCODE  


SQL>alter table Supply_master rename column ADDRESS1 TO ADDR;

 Name                   
 -----------------------
 SUPPLIER_NO            
 SUPPLIER_NAME          
 ADDR   ///////////this has been renamed........//////////////                
 ADDRESS2               
 CITY                   
 STATE                  
 PINCODE                  

// apparently this is broken. Whoops for me!
java.util.Collections.fill(list,new Integer(0));

// this is better
Integer[] data = new Integer[60];
Arrays.fill(data,new Integer(0));
List<Integer> list = Arrays.asList(data);

For number from 0 to 255 I use this regex:

(([0-9])|([1-9][0-9])|(1([0-9]{2}))|(2[0-4][0-9])|(25[0-5]))

Above regex will match integer number from 0 to 255, but not match 256.

So for IPv4 I use this regex:

^(([0-9])|([1-9][0-9])|(1([0-9]{2}))|(2[0-4][0-9])|(25[0-5]))((\.(([0-9])|([1-9][0-9])|(1([0-9]{2}))|(2[0-4][0-9])|(25[0-5]))){3})$

It is in this structure: ^(N)((\.(N)){3})$ where N is the regex used to match number from 0 to 255.
This regex will match IP like below:

0.0.0.0
192.168.1.2

but not those below:

10.1.0.256
1.2.3.
127.0.1-2.3

For IPv4 CIDR (Classless Inter-Domain Routing) I use this regex:

^(([0-9])|([1-9][0-9])|(1([0-9]{2}))|(2[0-4][0-9])|(25[0-5]))((\.(([0-9])|([1-9][0-9])|(1([0-9]{2}))|(2[0-4][0-9])|(25[0-5]))){3})\/(([0-9])|([12][0-9])|(3[0-2]))$

It is in this structure: ^(N)((\.(N)){3})\/M$ where N is the regex used to match number from 0 to 255, and M is the regex used to match number from 0 to 32.
This regex will match CIDR like below:

0.0.0.0/0
192.168.1.2/32

but not those below:

10.1.0.256/16
1.2.3./24
127.0.0.1/33

And for list of IPv4 CIDR like "10.0.0.0/16", "192.168.1.1/32" I use this regex:

^("(([0-9])|([1-9][0-9])|(1([0-9]{2}))|(2[0-4][0-9])|(25[0-5]))((\.(([0-9])|([1-9][0-9])|(1([0-9]{2}))|(2[0-4][0-9])|(25[0-5]))){3})\/(([0-9])|([12][0-9])|(3[0-2]))")((,([ ]*)("(([0-9])|([1-9][0-9])|(1([0-9]{2}))|(2[0-4][0-9])|(25[0-5]))((\.(([0-9])|([1-9][0-9])|(1([0-9]{2}))|(2[0-4][0-9])|(25[0-5]))){3})\/(([0-9])|([12][0-9])|(3[0-2]))"))*)$

It is in this structure: ^(“C”)((,([ ]*)(“C”))*)$ where C is the regex used to match CIDR (like 0.0.0.0/0).
This regex will match list of CIDR like below:

“10.0.0.0/16”,”192.168.1.2/32”, “1.2.3.4/32”

but not those below:

“10.0.0.0/16” 192.168.1.2/32 “1.2.3.4/32”

Maybe it might get shorter but for me it is easy to understand so fine by me.

Hope it helps!

for swift 3

I know this is an old post, but i was having a problem like the OP and this is what i came up with.

Example of array you could pass. You could re order this if a particular order was required, but for this question this will do what is asked.

$argument_set = array (8 => 'lots', 5 => 'of', 1 => 'data', 2 => 'here');

This is manageable, easy to read and the data extraction points can be added and removed at a moments notice anywhere in coding and still avoid a massive rewrite. I used integer keys to tally with the OP original question but string keys could be used just as easily. In fact for readability I would advise it.

Stick this in an external file for ease

function unknown_number_arguments($argument_set) {

    foreach ($argument_set as $key => $value) {

        # create a switch with all the cases you need. as you loop the array 
        # keys only your submitted $keys values will be found with the switch. 
        switch ($key) {
            case 1:
                # do stuff with $value
                break;
            case 2:
                # do stuff with $value;
                break;
            case 3:
                # key 3 omitted, this wont execute 
                break;
            case 5:
                # do stuff with $value;
                break;
            case 8:
                # do stuff with $value;
                break;
            default:
                # no match from the array, do error logging?
                break;
        }
    }
return;
}

put this at the start if the file.

$argument_set = array(); 

Just use these to assign the next piece of data use numbering/naming according to where the data is coming from.

$argument_set[1][] = $some_variable; 

And finally pass the array

unknown_number_arguments($argument_set);

return only makes sense inside a function. There is no function in your code.

Also, your code is worthy if the Department of Redundancy Department. Assuming you move it to a proper function, this would be better:

return confirm(".json_encode($message).");

EDIT much much later: Changed code to use json_encode to ensure the message contents don't break just because of an apostrophe in the message.

Looking at your example, I think this is what you want:

var dict = TableObj.ToDictionary(t => t.Key, t=> t.TimeStamp);

In C# (Sharp), you can make an empty character as '\0'. Maybe you can do this:

String.prototype.replaceAt = function (index, char) {
return this.substr(0, index) + char + this.substr(index + char.length);
}
mystring.replaceAt(4, '\0')

Search on google or surf on the interent and check if javascript allows you to make empty characters, like C# does. If yes, then learn how to do it, and maybe the replaceAt function will work at last, and you'll achieve what you want!

Finally that 'r' character will be removed!

Using sprintf was already proposed by ldueck in a comment, but I think this is worth being an answer:

f(i) = sprintf('f%d', i);

This is in my opinion the most readable solution and also gives some nice flexibility (i.e. when you want to round a float value, use something like %.2f).

You can also use something like

<c:if test="${ testObject.testPropert == "testValue" }">...</c:if>

I found this one more helpful and simple

DECLARE @StartTime datetime,@EndTime datetime   
SELECT @StartTime=GETDATE() 
--Your Query to be run goes here--  
SELECT @EndTime=GETDATE()   
SELECT DATEDIFF(ms,@StartTime,@EndTime) AS [Duration in milliseconds]   

You didn't bind all your bindings here

$sql = "SELECT SQL_CALC_FOUND_ROWS *, UNIX_TIMESTAMP(publicationDate) AS publicationDate     FROM comments WHERE articleid = :art 
ORDER BY " . mysqli_escape_string($order) . " LIMIT :numRows";

$st = $conn->prepare( $sql );
$st->bindValue( ":art", $art, PDO::PARAM_INT );

You've declared a binding called :numRows but you never actually bind anything to it.

UPDATE 2019: I keep getting upvotes on this and that reminded me of another suggestion

Double quotes are string interpolation in PHP, so if you're going to use variables in a double quotes string, it's pointless to use the concat operator. On the flip side, single quotes are not string interpolation, so if you've only got like one variable at the end of a string it can make sense, or just use it for the whole string.

In fact, there's a micro op available here since the interpreter doesn't care about parsing the string for variables. The boost is nearly unnoticable and totally ignorable on a small scale. However, in a very large application, especially good old legacy monoliths, there can be a noticeable performance increase if strings are used like this. (and IMO, it's easier to read anyway)

You simply have to set the state of the your button self.x to normal:

self.x['state'] = 'normal'

or

self.x.config(state="normal")

This code would go in the callback for the event that will cause the Button to be enabled.

Also, the right code should be:

self.x = Button(self.dialog, text="Download", state=DISABLED, command=self.download)
self.x.pack(side=LEFT)

The method pack in Button(...).pack() returns None, and you are assigning it to self.x. You actually want to assign the return value of Button(...) to self.x, and then, in the following line, use self.x.pack().

If using Nginx and getting a similar problem, then this might help:

Scan your domain on this sslTesturl, and see if the connection is allowed for your device version.

If lower version devices(like < Android 4.4.2 etc) are not able to connect due to TLS support, then try adding this to your Nginx config file,

ssl_protocols TLSv1 TLSv1.1 TLSv1.2;

Try using TestContext.WriteLine() which outputs text in test results.

Example:

[TestClass]
public class UnitTest1
{
    private TestContext testContextInstance;

    /// <summary>
    /// Gets or sets the test context which provides
    /// information about and functionality for the current test run.
    /// </summary>
    public TestContext TestContext
    {
        get { return testContextInstance; }
        set { testContextInstance = value; }
    }

    [TestMethod]
    public void TestMethod1()
    {
        TestContext.WriteLine("Message...");
    }
}

The "magic" is described in MSDN:

To use TestContext, create a member and property within your test class [...] The test framework automatically sets the property, which you can then use in unit tests.

All of these suggestions are great and all, but they're either only fixing either the header or a column, not both, or they're using javascript. The reason - it don't believe it can be done in pure CSS. The reason:

If it were possible to do it, you would need to nest several scrollable divs one inside the other, each with a scroll in a different direction. Then you would need to split your table into three parts - the fixed header, the fixed column and the rest of the data.

Fine. But now the problem - you can make one of them stay put when you scroll, but the other one is nested inside the scrolling area of first and is therefore subject to being scrolled out of sight itself, so can't be fixed in place on the screen. 'Ah-ha' you say 'but I can somehow use absolute or fixed position to do that' - no you can't. As soon as you do that you lose the ability to scroll that container. It's a chicken and egg situation - you can't have both, they cancel each other out.

I believe the only solution is through javascript. You need to completely seperate out the three elements and keep their positions in sync through javascript. There are good examples in other posts on this page. This one is also worth a look:

http://tympanus.net/codrops/2014/01/09/sticky-table-headers-columns/

for (let i = 0; i <= value; i+=n) { // increments by n
/*code statement*/
}

this format works for me incrementing index by n

for (let i = 0; i <= value; i+=4) { // increments by 4
/*code statement*/
}

if n = 4 this it will increment by 4

Even though this question was long time ago, thanks all for the inputs that helping me out a similar problem. I also made a bit modification based on the others' answers here and making multiple inputs/valuables into a Single Object (json); and hope this helps someone.

js:

//example: params={id:'123',name:'foo'};

mapInput.name = "data";
mapInput.value = JSON.stringify(params); 

php:

$data=json_decode($_POST['data']); 

echo $data->id;
echo $data->name;

This is probably not the main reason why the create_all() method call doesn't work for people, but for me, the cobbled together instructions from various tutorials have it such that I was creating my db in a request context, meaning I have something like:

# lib/db.py
from flask import g, current_app
from flask_sqlalchemy import SQLAlchemy

def get_db():
  if 'db' not in g:
    g.db = SQLAlchemy(current_app)
  return g.db

I also have a separate cli command that also does the create_all:

# tasks/db.py
from lib.db import get_db

@current_app.cli.command('init-db')
def init_db():
  db = get_db()
  db.create_all()

I also am using a application factory.

When the cli command is run, a new app context is used, which means a new db is used. Furthermore, in this world, an import model in the init_db method does not do anything, because it may be that your model file was already loaded(and associated with a separate db).

The fix that I came around to was to make sure that the db was a single global reference:

# lib/db.py
from flask import g, current_app
from flask_sqlalchemy import SQLAlchemy

db = None
def get_db():
  global db
  if not db:
    db = SQLAlchemy(current_app)
  return db

I have not dug deep enough into flask, sqlalchemy, or flask-sqlalchemy to understand if this means that requests to the db from multiple threads are safe, but if you're reading this you're likely stuck in the baby stages of understanding these concepts too.

Regarding 4., you still need to ensure that your "dummy script stub" is actually the target URL after all the rewriting is done, or you won't see anything!

A similar/related trick (see this question) is to insert a temporary rule such as:

RewriteRule (.*) /show.php?url=$1 [END]

Where show.php is some very simple script that just displays its $_GET parameters (you can display environment variables too, if you want).

This will stop the rewriting at the point you insert it into the ruleset, rather like a breakpoint in a debugger.

If you're using Apache <2.3.9, you'll need to use [L] rather than [END], and you may then need to add:

RewriteRule ^show.php$ - [L]

At the very top of your ruleset, if the URL /show.php is itself being rewritten.

void setup() {
// put your setup code here, to run once:
Serial.begin(115200);

}

void loop() {

Serial.println("This is Line ZERO ");

// put your main code here, to run repeatedly:

for (int i = 1; i < 37; i++)
{

 // Check and print Line
  if (i == 15)
  {
   Serial.println("Line 15");
  }

  else
   Serial.println(i);  //Prints line numbers   Delete i for blank line
  }

  delay(5000);  

  }

Here's a command I think could be of some help :

apachectl -t -D DUMP_VHOSTS

You'll get a list of all the vhosts, you'll know which one is the default one and you'll make sure that your syntax is correct (same as apachectl configtest suggested by yojimbo87).

You'll also know where each vhost is declared. It can be handy if your config files are a mess. ;)

You could use document.write.

Without jQuery

<!DOCTYPE html>
<html>
<head><meta charset=utf-8></head>
<body onload="document.write('<!doctype html><html><head><meta charset=utf-8></head><body><p>You cannot find this in the page source. (Your page needs to be in this document.write argument.)</p></body></html>');">
</body></html>

Or with jQuery

$(function () {
  document.write("<!doctype html><html><head><meta charset=utf-8></head><body><p>You cannot find this in the page source. (Your page needs to be in this document.write argument.)</p></body></html>")
});

use Date.prototype.toLocaleTimeString() as documented here

please note the locale example en-US in the url.

$this->db1->where('tennant_id', $tennant_id);
$this->db1->order_by('id', 'DESC');
return $this->db1->get('courses')->result();

if there is no value inserted, the default value should be null,empty

In the table definition, make this datetime column allows null, be not defining NOT NULL:

...
DateTimeColumn DateTime,
...

I HAVE ALLOWED NULL VARIABLES THOUGH.

Then , just insert NULL in this column:

INSERT INTO Table(name, datetimeColumn, ...)
VALUES('foo bar', NULL, ..);

Or, you can make use of the DEFAULT constaints:

...
DateTimeColumn DateTime DEFAULT NULL,
...

Then you can ignore it completely in the INSERT statement and it will be inserted withe the NULL value:

INSERT INTO Table(name, ...)
VALUES('foo bar', ..);

I ran into a similar limitation with DataTriggers, and it would seem that you can only check for equality. The closest thing I've seen that might help you is a technique for doing other types of comparisons other than equality.

This blog post describes how to do comparisons such as LT, GT, etc in a DataTrigger.

This limitation of the DataTrigger can be worked around to some extent by using a Converter to massage the data into a special value you can then compare against, as suggested in Robert Macnee's answer.

I'm sure that the above answers work perfectly. However, I had the difficulty of adding the double quotes as my bash lines where closer to 100. So, the following way helped me. (In a nutshell, no double quotes around each line of the shell)

Also, when I had "bash '''#!/bin/bash" within steps, I got the following error java.lang.NoSuchMethodError: No such DSL method '**bash**' found among steps

pipeline {
    agent none

    stages {

        stage ('Hello') {
            agent any

            steps {
                echo 'Hello, '

                sh '''#!/bin/bash

                    echo "Hello from bash"
                    echo "Who I'm $SHELL"
                '''
            }
        }
    }
}

The result of the above execution is

You just need to use single quotes:

$ echo "$TEST"
test
$ echo '$TEST'
$TEST

Inside single quotes special characters are not special any more, they are just normal characters.

Place it inside another div, use CSS to move the button to the middle:

<div style="width:100%;height:100%;position:absolute;vertical-align:middle;text-align:center;">
    <button type="button" style="background-color:yellow;margin-left:auto;margin-right:auto;display:block;margin-top:22%;margin-bottom:0%">
mybuttonname</button> 
</div>?

str_pad($input, 990); //so that the spaces will pad out to the 990 cut off.

When it comes to float numbers, you can use format specifiers:

f'{value:{width}.{precision}}'

where:

• value is any expression that evaluates to a number
• width specifies the number of characters used in total to display, but if value needs more space than the width specifies then the additional space is used.
• precision indicates the number of characters used after the decimal point

What you are missing is the type specifier for your decimal value. In this link, you an find the available presentation types for floating point and decimal.

Here you have some examples, using the f (Fixed point) presentation type:

# notice that it adds spaces to reach the number of characters specified by width
In [1]: f'{1 + 3 * 1.5:10.3f}'
Out[1]: '     5.500'

# notice that it uses more characters than the ones specified in width
In [2]: f'{3000 + 3 ** (1 / 2):2.1f}' 
Out[2]: '3001.7'

In [3]: f'{1.2345 + 4 ** (1 / 2):9.6f}'
Out[3]: ' 3.234500'

# omitting width but providing precision will use the required characters to display the number with the the specified decimal places
In [4]: f'{1.2345 + 3 * 2:.3f}' 
Out[4]: '7.234'

# not specifying the format will display the number with as many digits as Python calculates
In [5]: f'{1.2345 + 3 * 0.5}'
Out[5]: '2.7344999999999997'

If you want to make transformation your app setting from web config file to web.Release.config,you have to do the following steps. Let your web.config app setting file is this-

<appSettings>
     <add key ="K1" value="Debendra Dash"/>
  </appSettings>

Now here is the web.Release.config for the transformation.

<appSettings>
    <add key="K1" value="value dynamicly from Realease"
       xdt:Transform="SetAttributes"
          xdt:Locator="Match(key)"   
         />
  </appSettings>

This will transform the value of K1 to the new value in realese Mode.

Method document.getElementsByName returns an array of elements. You should select first, for example.

document.getElementsByName('acc')[0].value

Just a side note, in Python 2.0 you could compare anything to anything (int to string). As this wasn't explicit, it was changed in 3.0, which is a good thing as you are not running into the trouble of comparing senseless values with each other or when you forget to convert a type.

There is a free and open-source GUI tool KeyStore Explorer to work with crypto key containers. Using it you can export a certificate or private key into separate files or convert the container into another format (jks, pem, p12, pkcs12, etc)

You need to add a name to your <select> element:

<select id="testSelect" name="testSelect">

It will be posted to the server, and you can see it using:

Request.Form["testSelect"]

After some research and testing, I found that I had some misunderstandings about the lifetime of Docker containers. Simply restarting a container doesn't make Docker use a new image, when the image was rebuilt in the meantime. Instead, Docker is fetching the image only before creating the container. So the state after running a container is persistent.

Why removing is required

Therefore, rebuilding and restarting isn't enough. I thought containers works like a service: Stopping the service, do your changes, restart it and they would apply. That was my biggest mistake.

Because containers are permanent, you have to remove them using docker rm <ContainerName> first. After a container is removed, you can't simply start it by docker start. This has to be done using docker run, which itself uses the latest image for creating a new container-instance.

Containers should be as independent as possible

With this knowledge, it's comprehensible why storing data in containers is qualified as bad practice and Docker recommends data volumes/mounting host directorys instead: Since a container has to be destroyed to update applications, the stored data inside would be lost too. This cause extra work to shutdown services, backup data and so on.

So it's a smart solution to exclude those data completely from the container: We don't have to worry about our data, when its stored safely on the host and the container only holds the application itself.

Why -rf may not really help you

The docker run command, has a Clean up switch called -rf. It will stop the behavior of keeping docker containers permanently. Using -rf, Docker will destroy the container after it has been exited. But this switch has two problems:

1. Docker also remove the volumes without a name associated with the container, which may kill your data
2. Using this option, its not possible to run containers in the background using -d switch

While the -rf switch is a good option to save work during development for quick tests, it's less suitable in production. Especially because of the missing option to run a container in the background, which would mostly be required.

How to remove a container

We can bypass those limitations by simply removing the container:

docker rm --force <ContainerName>

The --force (or -f) switch which use SIGKILL on running containers. Instead, you could also stop the container before:

docker stop <ContainerName>
docker rm <ContainerName>

Both are equal. docker stop is also using SIGTERM. But using --force switch will shorten your script, especially when using CI servers: docker stop throws an error if the container is not running. This would cause Jenkins and many other CI servers to consider the build wrongly as failed. To fix this, you have to check first if the container is running as I did in the question (see containerRunning variable).

Full script for rebuilding a Docker container

According to this new knowledge, I fixed my script in the following way:

#!/bin/bash
imageName=xx:my-image
containerName=my-container

docker build -t $imageName -f Dockerfile  .

echo Delete old container...
docker rm -f $containerName

echo Run new container...
docker run -d -p 5000:5000 --name $containerName $imageName

This works perfectly :)
