In the Javascript community, lots of people argue that OOP should not be used because the prototype model does not allow to do a strict and robust OOP natively. However, I don't think that OOP is a matter of langage but rather a matter of architecture.

If you want to use a real strong OOP in Javascript/Node, you can have a look at the full-stack open source framework Danf. It provides all needed features for a strong OOP code (classes, interfaces, inheritance, dependency-injection, ...). It also allows you to use the same classes on both the server (node) and client (browser) sides. Moreover, you can code your own danf modules and share them with anybody thanks to Npm.

According to the fine manual, createConnection() can be used to connect to multiple databases.

However, you need to create separate models for each connection/database:

var conn      = mongoose.createConnection('mongodb://localhost/testA');
var conn2     = mongoose.createConnection('mongodb://localhost/testB');

// stored in 'testA' database
var ModelA    = conn.model('Model', new mongoose.Schema({
  title : { type : String, default : 'model in testA database' }
}));

// stored in 'testB' database
var ModelB    = conn2.model('Model', new mongoose.Schema({
  title : { type : String, default : 'model in testB database' }
}));

I'm pretty sure that you can share the schema between them, but you have to check to make sure.

You can use res.json() to jsonify any object. lean() will remove all the empty fields in the mongoose query.

UserModel.find().lean().exec(function (err, users) { return res.json(users); }

The problem can be solved by giving the port number and using this parser: {useNewUrlParser: true}

The solution can be:

mongoose.connect("mongodb://localhost:27017/cat_app", { useNewUrlParser: true });

It solves my problem.

The _id field is always present unless you explicitly exclude it. Do so using the - syntax:

exports.someValue = function(req, res, next) {
    //query with mongoose
    var query = dbSchemas.SomeValue.find({}).select('name -_id');

    query.exec(function (err, someValue) {
        if (err) return next(err);
        res.send(someValue);
    });
};

Or explicitly via an object:

exports.someValue = function(req, res, next) {
    //query with mongoose
    var query = dbSchemas.SomeValue.find({}).select({ "name": 1, "_id": 0});

    query.exec(function (err, someValue) {
        if (err) return next(err);
        res.send(someValue);
    });
};

In MongoDB, the db.collection.remove() method removes documents from a collection. You can remove all documents from a collection, remove all documents that match a condition, or limit the operation to remove just a single document.

Source: Mongodb.

If you are using mongo sheel, just do:

db.Datetime.remove({})

In your case, you need:

You didn't show me the delete button, so this button is just an example:

<a class="button__delete"></a>

Change the controller to:

exports.destroy = function(req, res, next) {
    Datetime.remove({}, function(err) {
            if (err) {
                console.log(err)
            } else {
                res.end('success');
            }
        }
    );
};

Insert this ajax delete method in your client js file:

        $(document).ready(function(){
            $('.button__delete').click(function() {
                var dataId = $(this).attr('data-id');

                if (confirm("are u sure?")) {
                    $.ajax({
                        type: 'DELETE',
                        url: '/',
                        success: function(response) {
                            if (response == 'error') {
                                console.log('Err!');
                            }
                            else {
                                alert('Success');
                                location.reload();
                            }
                        }
                    });
                } else {
                    alert('Canceled!');
                }
            });
        });

For me,issue was mongo was not running.So first i started "mongod" command in the console.And later in another console tab I have run "mongo". Now the connection is successful. Now run your app your problem should be solved.

If you'd want to use something like a "contains" operator through javascript, you can always use a Regular expression for that...

eg. Say you want to retrieve a customer having "Bartolomew" as name

async function getBartolomew() {
    const custStartWith_Bart = await Customers.find({name: /^Bart/ }); // Starts with Bart
    const custEndWith_lomew = await Customers.find({name: /lomew$/ }); // Ends with lomew
    const custContains_rtol = await Customers.find({name: /.*rtol.*/ }); // Contains rtol

    console.log(custStartWith_Bart);
    console.log(custEndWith_lomew);
    console.log(custContains_rtol);
}

OR you can do this

var ObjectId = require('mongoose').Types.ObjectId; var objId = new ObjectId( (param.length < 12) ? "123456789012" : param );

as mentioned here Mongoose's find method with $or condition does not work properly

I created an example that uses Express and Multer. It is very simple and avoids all Connect warnings

It might help somebody.

The result returned by find is an array.

Try this instead:

console.log(user[0]["_id"]);

That should work if the dates you saved in the DB are without time (just year, month, day).

Chances are that the dates you saved were new Date(), which includes the time components. To query those times you need to create a date range that includes all moments in a day.

db.posts.find({ //query today up to tonight
    created_on: {
        $gte: new Date(2012, 7, 14), 
        $lt: new Date(2012, 7, 15)
    }
})

It's probably easiest to create your query object directly as:

  Test.find({
      $and: [
          { $or: [{a: 1}, {b: 1}] },
          { $or: [{c: 1}, {d: 1}] }
      ]
  }, function (err, results) {
      ...
  }

But you can also use the Query#and helper that's available in recent 3.x Mongoose releases:

  Test.find()
      .and([
          { $or: [{a: 1}, {b: 1}] },
          { $or: [{c: 1}, {d: 1}] }
      ])
      .exec(function (err, results) {
          ...
      });

I was having the same problem.Turns out my Node.js was outdated. After upgrading it's working.

Mongoose basically wraps mongodb's api to give you a pseudo relational db api so queries are not going to be exactly like mongodb queries. Mongoose findOne query returns a query object, not a document. You can either use a callback as the solution suggests or as of v4+ findOne returns a thenable so you can use .then or await/async to retrieve the document.

// thenables
Auth.findOne({nick: 'noname'}).then(err, result) {console.log(result)};
Auth.findOne({nick: 'noname'}).then(function (doc) {console.log(doc)});

// To use a full fledge promise you will need to use .exec()
var auth = Auth.findOne({nick: 'noname'}).exec();
auth.then(function (doc) {console.log(doc)});

// async/await
async function auth() {
  const doc = await Auth.findOne({nick: 'noname'}).exec();
  return doc;
}
auth();

See the docs if you would like to use a third party promise library.

In order to populate referenced subdocuments, you need to explicitly define the document collection to which the ID references to (like created_by: { type: Schema.Types.ObjectId, ref: 'User' }).

Given this reference is defined and your schema is otherwise well defined as well, you can now just call populate as usual (e.g. populate('comments.created_by'))

Proof of concept code:

// Schema
var mongoose = require('mongoose');
var Schema = mongoose.Schema;

var UserSchema = new Schema({
  name: String
});

var CommentSchema = new Schema({
  text: String,
  created_by: { type: Schema.Types.ObjectId, ref: 'User' }
});

var ItemSchema = new Schema({
   comments: [CommentSchema]
});

// Connect to DB and instantiate models    
var db = mongoose.connect('enter your database here');
var User = db.model('User', UserSchema);
var Comment = db.model('Comment', CommentSchema);
var Item = db.model('Item', ItemSchema);

// Find and populate
Item.find({}).populate('comments.created_by').exec(function(err, items) {
    console.log(items[0].comments[0].created_by.name);
});

Finally note that populate works only for queries so you need to first pass your item into a query and then call it:

item.save(function(err, item) {
    Item.findOne(item).populate('comments.created_by').exec(function (err, item) {
        res.json({
            status: 'success',
            message: "You have commented on this item",
            comment: item.comments.id(comment._id)
        });
    });
});

{ $where: "this.pictures.length > 1" }

use the $where and pass the this.field_name.length which return the size of array field and check it by comparing with number. if any array have any value than array size must be at least 1. so all the array field have length more than one, it means it have some data in that array

{ "date" : "1000000" } in your Mongo doc seems suspect. Since it's a number, it should be { date : 1000000 }

It's probably a type mismatch. Try post.findOne({date: "1000000"}, callback) and if that works, you have a typing issue.

var mongoose = require('mongoose');
var _id = mongoose.mongo.ObjectId("4eb6e7e7e9b7f4194e000001");

Mongo is NoSQL Database.

If you don't want to use any ORM for your data models then you can also use native driver mongo.js: https://github.com/mongodb/node-mongodb-native.

Mongoose is one of the orm's who give us functionality to access the mongo data with easily understandable queries.

Mongoose plays as a role of abstraction over your database model.

In this case, you can add the query page and/ or limit to your URL as a query string.

For example:
?page=0&limit=25 // this would be added onto your URL: http:localhost:5000?page=0&limit=25

Since it would be a String we need to convert it to a Number for our calculations. Let's do it using the parseInt method and let's also provide some default values.

const pageOptions = {
    page: parseInt(req.query.page, 10) || 0,
    limit: parseInt(req.query.limit, 10) || 10
}

sexyModel.find()
    .skip(pageOptions.page * pageOptions.limit)
    .limit(pageOptions.limit)
    .exec(function (err, doc) {
        if(err) { res.status(500).json(err); return; };
        res.status(200).json(doc);
    });

BTW Pagination starts with 0

I implore everyone to use Mongoose's query builder language and promises instead of callbacks:

User.find().or([{ name: param }, { nickname: param }])
    .then(users => { /*logic here*/ })
    .catch(error => { /*error logic here*/ })

Read more about Mongoose Queries.

You can also stringify the object and then again parse to make the normal object. For example like:-

const obj = JSON.parse(JSON.stringify(mongoObj))

In mongoDB, they deprecated current server and engine monitoring package, so you need to use new server and engine monitoring package. So you just use

{ useUnifiedTopology:true }

mongoose.connect("paste db link", {useUnifiedTopology: true, useNewUrlParser: true, useCreateIndex: true });

Just complementing @PeterBechP 's answer.

Don't forget to scape the special chars. https://stackoverflow.com/a/6969486

function escapeRegExp(string) {
  return string.replace(/[.*+?^${}()|[\]\\]/g, '\\$&');
}

var name = 'Peter+with+special+chars';

model.findOne({name: new RegExp('^'+escapeRegExp(name)+'$', "i")}, function(err, doc) {
  //Do your action here..
});

For my case, I npm install all modules on my local machine (Mac), and I did not include node_modules in .gitignore and uploaded to github. Then I cloned the project to my aws, as you know, it is running Linux, so I got the errors. What I did is just include node_modules in .gitignore, and use npm install in my aws instance, then it works.

Using mongoose here, but you could do a similar check without it

export async function clearDatabase() {
  if (mongoose.connection.readyState === mongoose.connection.states.disconnected) {
    return Promise.resolve()
  }
  return mongoose.connection.db.dropDatabase()
}

My use case was just tests throwing errors, so if we've disconnected, I don't run operations.

I was looking for a different answer for the question title, so maybe other people will be too.

To set type as an ObjectId (so you may reference author as the author of book, for example), you may do like:

const Book = mongoose.model('Book', {
  author: {
    type: mongoose.Schema.Types.ObjectId, // here you set the author ID
                                          // from the Author colection, 
                                          // so you can reference it
    required: true
  },
  title: {
    type: String,
    required: true
  }
});

I'm the maintainer of Mongoose. findById() is a built-in method on Mongoose models. findById(id) is equivalent to findOne({ _id: id }), with one caveat: findById() with 0 params is equivalent to findOne({ _id: null }).

You can read more about findById() on the Mongoose docs and this findById() tutorial.

In my case, I did this

  const eventId = event.id;
  User.findByIdAndUpdate(id, { $push: { createdEvents: eventId } }).exec();

There is a mongoose way for doing it.

const itemId = 2;
const query = {
  item._id: itemId 
};
Person.findOne(query).then(doc => {
  item = doc.items.id(itemId );
  item["name"] = "new name";
  item["value"] = "new value";
  doc.save();

  //sent respnse to client
}).catch(err => {
  console.log('Oh! Dark')
});

findOne, modify fields & save

User.findOne({username: oldUsername})
  .then(user => {
    user.username = newUser.username;
    user.password = newUser.password;
    user.rights = newUser.rights;

    user.markModified('username');
    user.markModified('password');
    user.markModified('rights');

    user.save(err => console.log(err));
});

OR findOneAndUpdate

User.findOneAndUpdate({username: oldUsername}, {$set: { username: newUser.username, user: newUser.password, user:newUser.rights;}}, {new: true}, (err, doc) => {
    if (err) {
        console.log("Something wrong when updating data!");
    }
    console.log(doc);
});

Also see updateOne

You can set the connection to a variable then disconnect it when you are done:

var db = mongoose.connect('mongodb://localhost:27017/somedb');

// Do some stuff

db.disconnect();

I do this:

Data.find( { $query: { user: req.user }, $orderby: { dateAdded: -1 } } function ( results ) {
    ...
})

This will show the most recent things first.

Here is another way without using additional libraries (no error checking included)

function saveAll( callback ){
  var count = 0;
  docs.forEach(function(doc){
      doc.save(function(err){
          count++;
          if( count == docs.length ){
             callback();
          }
      });
  });
}

Mongoose 4.5 support this

Project.find(query)
  .populate({ 
     path: 'pages',
     populate: {
       path: 'components',
       model: 'Component'
     } 
  })
  .exec(function(err, docs) {});

And you can join more than one deep level

Edit - 20 March 2016

Mongoose now support timestamps for collections.

Please consider the answer of @bobbyz below. Maybe this is what you are looking for.

Original answer

Mongoose supports a Date type (which is basically a timestamp):

time : { type : Date, default: Date.now }

With the above field definition, any time you save a document with an unset time field, Mongoose will fill in this field with the current time.

Source: http://mongoosejs.com/docs/guide.html

Ids is the array of object ids:

const ids =  [
    '4ed3ede8844f0f351100000c',
    '4ed3f117a844e0471100000d', 
    '4ed3f18132f50c491100000e',
];

Using Mongoose with callback:

Model.find().where('_id').in(ids).exec((err, records) => {});

Using Mongoose with async function:

const records = await Model.find().where('_id').in(ids).exec();

Or more concise:

const records = await Model.find({ '_id': { $in: ids } });

Don't forget to change Model with your actual model.

This coffeescript works for me with Node - the trick is that the _id get's stripped of its ObjectID wrapper when sent and returned from the client and so this needs to be replaced for updates (when no _id is provided, save will revert to insert and add one).

app.post '/new', (req, res) ->
    # post data becomes .query
    data = req.query
    coll = db.collection 'restos'
    data._id = ObjectID(data._id) if data._id

    coll.save data, {safe:true}, (err, result) ->
        console.log("error: "+err) if err
        return res.send 500, err if err

        console.log(result)
        return res.send 200, JSON.stringify result

Addendum: No one mentioned "Populate" --- it is very much worth your time and money looking at Mongooses Populate Method : Also explains cross documents referencing

http://mongoosejs.com/docs/populate.html

It's not a big issue but beginner level developers as like me, we things what kind of error is this and finally we weast huge time for solve it.

Actually if you delete the db and create the db once again and after try to create the collection then it's will be work properly.

? mongo
use dbName;
db.dropDatabase();
exit

ObjectIDs are objects so if you just compare them with == you're comparing their references. If you want to compare their values you need to use the ObjectID.equals method:

if (results.userId.equals(AnotherMongoDocument._id)) {
    ...
}

For some reason I could not get this to work with the proposed answers, but I found another variation, using select, that worked for me:

models.Post.find().sort('-date').limit(10).select('published').exec(function(e, data){
        ...
});

Has the api perhaps changed? I am using version 3.8.19

2020 update

make a new file call it drop.js i.e and put inside

require('dotenv').config()
const url = process.env.ATLAS_URI;
mongoose.connect(url, {
  useNewUrlParser: true,
  useCreateIndex: true,
  useUnifiedTopology: true,
  useFindAndModify: false
});

const connection = mongoose.connection;
connection.once('open', () => {
  console.log("MongoDB database connection established successfully");
})


mongoose.connection.dropDatabase().then(
  async() => {
   
    try {
      mongoose.connection.close()
     
    }
    catch (err) {
      console.log(err)
    }

 }
  
);

in your package.json

in your package.json 
 "scripts": {
    
    "drop": "node models/drop.js",
   
  }

run it on ur console and

Use a function to return the computed default value:

var ItemSchema = new Schema({
    name: {
      type: String,
      required: true,
      trim: true
    },
    created_at: {
      type: Date,
      default: function(){
        return Date.now();
      }
    },
    updated_at: {
      type: Date,
      default: function(){
        return Date.now();
      }
    }
});

ItemSchema.pre('save', function(done) {
  this.updated_at = Date.now();
  done();
});

If you're searching by an unique index, then using UserModel.count may actually be better for you than UserModel.findOne due to it returning the whole document (ie doing a read) instead of returning just an int.

Well, I can't see Tony's solution...so I have to handle it myself...

If you don't need version_key, you can just:

var UserSchema = new mongoose.Schema({
    nickname: String,
    reg_time: {type: Date, default: Date.now}
}, {
    versionKey: false // You should be aware of the outcome after set to false
});

Setting the versionKey to false means the document is no longer versioned.

This is problematic if the document contains an array of subdocuments. One of the subdocuments could be deleted, reducing the size of the array. Later on, another operation could access the subdocument in the array at it's original position.

Since the array is now smaller, it may accidentally access the wrong subdocument in the array.

The versionKey solves this by associating the document with the a versionKey, used by mongoose internally to make sure it accesses the right collection version.

More information can be found at: http://aaronheckmann.blogspot.com/2012/06/mongoose-v3-part-1-versioning.html

I don't know if this is really any different, but rather than iterate over the query cursor, you could do something like this:

query.exec(function (err, results){
  if (err) res.writeHead(500, err.message)
  else if (!results.length) res.writeHead(404);
  else {
    res.writeHead(200, { 'Content-Type': 'application/json' });
    res.write(JSON.stringify(results.map(function (msg){ return {msgId: msg.fileName}; })));
  }
  res.end();
});

You should be able to do this like (as you're using the query api):

Entrant.where("pincode").ne(null)

... which will result in a mongo query resembling:

entrants.find({ pincode: { $ne: null } })

A few links that might help:

• The mongoose query api
• The docs for mongo query operators

You should give an object as argument

userModel.count({name: "sam"});

or

userModel.count({name: "sam"}).exec(); //if you are using promise

or

userModel.count({}); // if you want to get all counts irrespective of the fields

On the recent version of mongoose, count() is deprecated so use

userModel.countDocuments({name: "sam"});

Indeed, you can use the "create" method of Mongoose, it can contain an array of documents, see this example:

Candy.create({ candy: 'jelly bean' }, { candy: 'snickers' }, function (err, jellybean, snickers) {
});

The callback function contains the inserted documents. You do not always know how many items has to be inserted (fixed argument length like above) so you can loop through them:

var insertedDocs = [];
for (var i=1; i<arguments.length; ++i) {
    insertedDocs.push(arguments[i]);
}

Update: A better solution

A better solution would to use Candy.collection.insert() instead of Candy.create() - used in the example above - because it's faster (create() is calling Model.save() on each item so it's slower).

See the Mongo documentation for more information: http://docs.mongodb.org/manual/reference/method/db.collection.insert/

(thanks to arcseldon for pointing this out)

With deferred (another promise/deferred implementation) you can do:

// Setup 'pdrop', promise version of 'drop' method
var deferred = require('deferred');
mongoose.Collection.prototype.pdrop =
    deferred.promisify(mongoose.Collection.prototype.drop);

// Drop collections:
deferred.map(['aaa','bbb','ccc'], function(name){
    return conn.collection(name).pdrop()(function () {
      console.log("dropped");
    });
}).end(function () {
    console.log("all dropped");
}, null);

Are you sure you've connected to the db? (I ask because I don't see a port specified)

try:

mongoose.connection.on("open", function(){
  console.log("mongodb is connected!!");
});

Also, you can do a "show collections" in mongo shell to see the collections within your db - maybe try adding a record via mongoose and see where it ends up?

From the look of your connection string, you should see the record in the "test" db.

Hope it helps!

I needed to generate mongodb ids on client side.

After digging into the mongodb source code i found they generate ObjectIDs using npm bson lib.

If ever you need only to generate an ObjectID without installing the whole mongodb / mongoose package, you can import the lighter bson library :

const bson = require('bson');
new bson.ObjectId(); // 5cabe64dcf0d4447fa60f5e2

Note: There is also an npm project named bson-objectid being even lighter

This is working for me and really very helpful.

SubCategory.update({ _id: { $in:
        arrOfSubCategory.map(function (obj) {
            return mongoose.Types.ObjectId(obj);
        })
    } },
    {
        $pull: {
            coupon: couponId,
        }
    }, { multi: true }, function (err, numberAffected) {
        if(err) {
            return callback({
                error:err
            })
        }
    })
});

I have a model which name is SubCategory and I want to remove Coupon from this category Array. I have an array of categories so I have used arrOfSubCategory. So I fetch each array of object from this array with map function with the help of $in operator.

In Mongoose, a sort can be done in any of the following ways:

    Post.find({}).sort('test').exec(function(err, docs) { ... });
    Post.find({}).sort([['date', -1]]).exec(function(err, docs) { ... });
    Post.find({}).sort({test: 1}).exec(function(err, docs) { ... });
    Post.find({}, null, {sort: {date: 1}}, function(err, docs) { ... });

Thanks for the replies.

I tried the first approach, but nothing changed. Then, I tried to log the results. I just drilled down level by level, until I finally got to where the data was being displayed.

After a while I found the problem: When I was sending the response, I was converting it to a string via .toString().

I fixed that and now it works brilliantly. Sorry for the false alarm.

you can also do it by async function to get all the users

await User.find({},(err,users)=>{

    if (err){
    return  res.status(422).send(err)
    }

    if (!users){
        return res.status(422).send({error:"No data in the collection"})
    }

    res.send({Allusers:users})

})

For whoever stumbled across this using ES6 / ES7 style with native promises, here is a pattern you can adopt...

const user = { id: 1, name: "Fart Face 3rd"};
const userUpdate = { name: "Pizza Face" };

try {
    user = await new Promise( ( resolve, reject ) => {
        User.update( { _id: user.id }, userUpdate, { upsert: true, new: true }, ( error, obj ) => {
            if( error ) {
                console.error( JSON.stringify( error ) );
                return reject( error );
            }

            resolve( obj );
        });
    })
} catch( error ) { /* set the world on fire */ }

just export like this exports.User = mongoose.models.User || mongoose.model('User', userSchema);

Instead of using 2 separate queries, you can use aggregate() in a single query:

Aggregate "$facet" can be fetch more quickly, the Total Count and the Data with skip & limit

    db.collection.aggregate([

      //{$sort: {...}}

      //{$match:{...}}

      {$facet:{

        "stage1" : [ {"$group": {_id:null, count:{$sum:1}}} ],

        "stage2" : [ { "$skip": 0}, {"$limit": 2} ]
  
      }},
     
     {$unwind: "$stage1"},
  
      //output projection
     {$project:{
        count: "$stage1.count",
        data: "$stage2"
     }}

 ]);

output as follows:-

[{
     count: 50,
     data: [
        {...},
        {...}
      ]
 }]

Also, have a look at https://docs.mongodb.com/manual/reference/operator/aggregation/facet/

From RFC 1945 (HTTP/1.0) and RFC 2617 (HTTP Authentication referenced by HTTP/1.1)

The realm attribute (case-insensitive) is required for all authentication schemes which issue a challenge. The realm value (case-sensitive), in combination with the canonical root URL of the server being accessed, defines the protection space. These realms allow the protected resources on a server to be partitioned into a set of protection spaces, each with its own authentication scheme and/or authorization database. The realm value is a string, generally assigned by the origin server, which may have additional semantics specific to the authentication scheme.

In short, pages in the same realm should share credentials. If your credentials work for a page with the realm "My Realm", it should be assumed that the same username and password combination should work for another page with the same realm.

As noted in the comments, this only works AFTER you've DataBound your repeater.

To find a control in the header:

lblControl = repeater1.Controls[0].Controls[0].FindControl("lblControl");

To find a control in the footer:

lblControl = repeater1.Controls[repeater1.Controls.Count - 1].Controls[0].FindControl("lblControl");

With extension methods

public static class RepeaterExtensionMethods
{
    public static Control FindControlInHeader(this Repeater repeater, string controlName)
    {
        return repeater.Controls[0].Controls[0].FindControl(controlName);
    }

    public static Control FindControlInFooter(this Repeater repeater, string controlName)
    {
        return repeater.Controls[repeater.Controls.Count - 1].Controls[0].FindControl(controlName);
    }
}

Install nmap,

sudo apt-get install nmap

then

nmap -sP 192.168.1.*

or more commonly

nmap -sn 192.168.1.0/24

will scan the entire .1 to .254 range

This does a simple ping scan in the entire subnet to see which hosts are online.

I had also same issue, I have just removed following line of code from BundleConfig.cs file and my code is working fine.

BundleTable.EnableOptimizations = true;

It is only possible as from C# 4.0

However, when you use a version of C#, prior to 4.0, you can work around this by using overloaded methods:

public void Func( int i, int j )
{
    Console.WriteLine (String.Format ("i = {0}, j = {1}", i, j));
}

public void Func( int i )
{
    Func (i, 4);
}

public void Func ()
{
    Func (5);
}

(Or, you can upgrade to C# 4.0 offcourse).

And if you want to run a second function after the first one finishes, see this stackoverflow answer.

The answers here are lacking in clarity, this is tested on Python 3.6

With this folder structure:

main.py
|
---- myfolder/myfile.py

Where myfile.py has the content:

def myfunc():
    print('hello')

The import statement in main.py is:

from myfolder.myfile import myfunc
myfunc()

and this will print hello.

Had the same Issue when i decided to install another version of Android Studio, what worked for me was:

• Creating a new project with the current version of Android Studio just to go check the classpath version at the project level build.gradle inside the dependencies section, at the time it was this:

classpath 'com.android.tools.build:gradle:3.5.0-rc01'

Copied that line and replaced it on the project i was working on.

If you want to commit on top of the current HEAD with the exact state at a different commit, undoing all the intermediate commits, then you can use reset to create the correct state of the index to make the commit.

# Reset the index and working tree to the desired tree
# Ensure you have no uncommitted changes that you want to keep
git reset --hard 56e05fced

# Move the branch pointer back to the previous HEAD
git reset --soft HEAD@{1}

git commit -m "Revert to 56e05fced"

This is an old question, but because this might help a lot of c# coders out there, there is an easy way to solve this right now as follows:

if ((dataTableName?.Rows?.Count ?? 0) > 0)

public Boolean test() throws InterruptedException {
    BlockingQueue<Boolean> booleanHolder = new LinkedBlockingQueue<>();
    new Thread(() -> {
        try {
            TimeUnit.SECONDS.sleep(2);
            booleanHolder.put(true);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }).start();
    return booleanHolder.poll(4, TimeUnit.SECONDS);
}

Code Safety Note

Regarding the accepted answer, it is important to use toSerialize.GetType() instead of typeof(T) in XmlSerializer constructor: if you use the first one the code covers all possible scenarios, while using the latter one fails sometimes.

Here is a link with some example code that motivate this statement, with XmlSerializer throwing an Exception when typeof(T) is used, because you pass an instance of a derived type to a method that calls SerializeObject<T>() that is defined in the derived type's base class: http://ideone.com/1Z5J1. Note that Ideone uses Mono to execute code: the actual Exception you would get using the Microsoft .NET runtime has a different Message than the one shown on Ideone, but it fails just the same.

For the sake of completeness I post the full code sample here for future reference, just in case Ideone (where I posted the code) becomes unavailable in the future:

using System;
using System.Xml.Serialization;
using System.IO;

public class Test
{
    public static void Main()
    {
        Sub subInstance = new Sub();
        Console.WriteLine(subInstance.TestMethod());
    }

    public class Super
    {
        public string TestMethod() {
            return this.SerializeObject();
        }
    }

    public class Sub : Super
    {
    }
}

public static class TestExt {
    public static string SerializeObject<T>(this T toSerialize)
    {
        Console.WriteLine(typeof(T).Name);             // PRINTS: "Super", the base/superclass -- Expected output is "Sub" instead
        Console.WriteLine(toSerialize.GetType().Name); // PRINTS: "Sub", the derived/subclass

        XmlSerializer xmlSerializer = new XmlSerializer(typeof(T));
        StringWriter textWriter = new StringWriter();

        // And now...this will throw and Exception!
        // Changing new XmlSerializer(typeof(T)) to new XmlSerializer(subInstance.GetType()); 
        // solves the problem
        xmlSerializer.Serialize(textWriter, toSerialize);
        return textWriter.ToString();
    }
}

It sounds like your site has CSS or JS that depends on running in quirks mode. Which is why you need garbage above your doctype to render "correctly". I suggest removing said garbage and then fixing your CSS+JS to actually work in standards mode; you'll save yourself a lot of pain in the long run.

Late resurrection.

Your query seems very similar to the one at page 259 of the book Pro JPA 2: Mastering the Java Persistence API, which in JPQL reads:

SELECT e 
FROM Employee e 
WHERE e IN (SELECT emp
              FROM Project p JOIN p.employees emp 
             WHERE p.name = :project)

Using EclipseLink + H2 database, I couldn't get neither the book's JPQL nor the respective criteria working. For this particular problem I have found that if you reference the id directly instead of letting the persistence provider figure it out everything works as expected:

SELECT e 
FROM Employee e 
WHERE e.id IN (SELECT emp.id
                 FROM Project p JOIN p.employees emp 
                WHERE p.name = :project)

Finally, in order to address your question, here is an equivalent strongly typed criteria query that works:

CriteriaBuilder cb = em.getCriteriaBuilder();
CriteriaQuery<Employee> c = cb.createQuery(Employee.class);
Root<Employee> emp = c.from(Employee.class);

Subquery<Integer> sq = c.subquery(Integer.class);
Root<Project> project = sq.from(Project.class);
Join<Project, Employee> sqEmp = project.join(Project_.employees);

sq.select(sqEmp.get(Employee_.id)).where(
        cb.equal(project.get(Project_.name), 
        cb.parameter(String.class, "project")));

c.select(emp).where(
        cb.in(emp.get(Employee_.id)).value(sq));

TypedQuery<Employee> q = em.createQuery(c);
q.setParameter("project", projectName); // projectName is a String
List<Employee> employees = q.getResultList();

Or for what seems like rampant overkill, but is actually simplistic ... Pretty much covers all of your cases, and no empty string or unary concerns.

In the case the first arg is '-v', then do your conditional ps -ef, else in all other cases throw the usage.

#!/bin/sh
case $1 in
  '-v') if [ "$1" = -v ]; then
         echo "`ps -ef | grep -v '\['`"
        else
         echo "`ps -ef | grep '\[' | grep root`"
        fi;;
     *) echo "usage: $0 [-v]"
        exit 1;; #It is good practice to throw a code, hence allowing $? check
esac

If one cares not where the '-v' arg is, then simply drop the case inside a loop. The would allow walking all the args and finding '-v' anywhere (provided it exists). This means command line argument order is not important. Be forewarned, as presented, the variable arg_match is set, thus it is merely a flag. It allows for multiple occurrences of the '-v' arg. One could ignore all other occurrences of '-v' easy enough.

#!/bin/sh

usage ()
 {
  echo "usage: $0 [-v]"
  exit 1
 }

unset arg_match

for arg in $*
 do
  case $arg in
    '-v') if [ "$arg" = -v ]; then
           echo "`ps -ef | grep -v '\['`"
          else
           echo "`ps -ef | grep '\[' | grep root`"
          fi
          arg_match=1;; # this is set, but could increment.
       *) ;;
  esac
done

if [ ! $arg_match ]
 then
  usage
fi

But, allow multiple occurrences of an argument is convenient to use in situations such as:

$ adduser -u:sam -s -f -u:bob -trace -verbose

We care not about the order of the arguments, and even allow multiple -u arguments. Yes, it is a simple matter to also allow:

$ adduser -u sam -s -f -u bob -trace -verbose

Here is an example of what I made to created ID's with my JavaScript.

function abs_demo_DemandeEnvoyee_absence(){

    var iDateInitiale = document.getElementById("abs_t_date_JourInitial_absence").value; /* On récupère la date initiale*/
    var iDateFinale = document.getElementById("abs_t_date_JourFinal_absence").value;     /*On récupère la date finale*/
    var sMotif = document.getElementById("abs_txt_motif_absence").value;                 /*On récupère le motif*/  
    var iCompteurDivNumero = 1;                                                         /*Le compteur est initialisé à 1 parce que la div 1 existe*/
    var TestDivVide = document.getElementById("abs_Autorisation_"+iCompteurDivNumero+"_absence") == undefined; //Boléenne, renvoie false si la div existe déjà
    var NewDivCreation = "";                                                            /*Initialisée en string vide pour concaténation*/
    var NewIdCreation;                                                                  /*Utilisée pour créer l'id d'une div dynamiquement*/
    var NewDivVersHTML;                                                                 /*Utilisée pour insérer la nouvelle div dans le html*/


    while(TestDivVide == false){                                                        /*Tant que la div pointée existe*/
        iCompteurDivNumero++;                                                           /*On incrémente le compteur de 1*/
        TestDivVide = document.getElementById("abs_Autorisation_"+iCompteurDivNumero+"_absence") == undefined; /*Abs_autorisation_1_ est écrite en dur.*/   
    }

    NewIdCreation = "abs_Autorisation_"+iCompteurDivNumero+"_absence"                   /*On crée donc la nouvelle ID de DIV*/

                                                                                        /*On crée la nouvelle DIV avec l'ID précédemment créée*/
    NewDivCreation += "<div class=\"abs_AutorisationsDynamiques_absence\" id=\""+NewIdCreation+"\">Votre demande d'autorisation d'absence du <b>"+iDateInitiale+"</b> au <b>"+iDateFinale+"</b>, pour le motif suivant : <i>\""+sMotif+"\"</i> a bien été <span class=\"abs_CouleurTexteEnvoye_absence\">envoyée</span>.</div>";

    document.getElementById("abs_AffichagePanneauDeControle_absence").innerHTML+=NewDivCreation; /*Et on concatenne la nouvelle div créée*/ 

    document.getElementById("abs_Autorisation_1_absence").style.display = 'none'; /*On cache la première div qui contient le message "vous n'avez pas de demande en attente" */

}

INSERT INTO LOCATION VALUES(PQ95VM,'HAPPY_STREET','FRANCE');

the above mentioned code is not correct because your first parameter POSTCODE is of type VARCHAR(10). you should have used ' '.

try INSERT INTO LOCATION VALUES('PQ95VM','HAPPY_STREET','FRANCE');

I use WinMerge. It is free and works pretty well (works for files and directories).

On OSX 10.8 and on, the control for MySQL is available from the System Configs. Open System Preferences, click on Mysql (usually on the very bottom) and start/stop the service from that pane. https://dev.mysql.com/doc/refman/5.6/en/osx-installation-launchd.html

The plist file is now under /Library/LaunchDaemons/com.oracle.oss.mysql.mysqld.plist

You can use Spannable to apply effects to your TextView:

Here is my example for colouring just the first part of a TextView text (while allowing you to set the color dynamically rather than hard coding it into a String as with the HTML example!)

    mTextView.setText("Red text is here", BufferType.SPANNABLE);
    Spannable span = (Spannable) mTextView.getText();
    span.setSpan(new ForegroundColorSpan(0xFFFF0000), 0, "Red".length(),
             Spannable.SPAN_INCLUSIVE_EXCLUSIVE);

In this example you can replace 0xFFFF0000 with a getResources().getColor(R.color.red)

For me the best way to do this is:

.container{
  position: relative;
}

.element{
  position: absolute;
  top: 50%;
  transform: translateY(-50%);
}

The advantage is not having to make the height explicit

The biggest disadvantage of Text (together with NText and Image) is that it will be removed in a future version of SQL Server, as by the documentation. That will effectively make your schema harder to upgrade when that version of SQL Server will be released.

First, set height greater than width. In theory, this is all you should need. The HTML5 Spec suggests as much:

... the UA determined the orientation of the control from the ratio of the style-sheet-specified height and width properties.

Opera had it implemented this way, but Opera is now using WebKit Blink. As of today, no browser implements a vertical slider based solely on height being greater than width.

Regardless, setting height greater than width is needed to get the layout right between browsers. Applying left and right padding will also help with layout and positioning.

For Chrome, use -webkit-appearance: slider-vertical.

For IE, use writing-mode: bt-lr.

For Firefox, add an orient="vertical" attribute to the html. Pity that they did it this way. Visual styles should be controlled via CSS, not HTML.

input[type=range][orient=vertical]
{
    writing-mode: bt-lr; /* IE */
    -webkit-appearance: slider-vertical; /* WebKit */
    width: 8px;
    height: 175px;
    padding: 0 5px;
}

<input type="range" orient="vertical" />

Disclaimers:

This solution is based on current browser implementations of as yet undefined or unfinalized CSS properties. If you intend to use it in your code, be prepared to make code adjustments as newer browser versions are released and w3c recommendations are completed.

MDN contains an explicit warning against using -webkit-appearance on the web:

Do not use this property on Web sites: not only is it non-standard, but its behavior change from one browser to another. Even the keyword none has not the same behavior on each form element on different browsers, and some doesn't support it at all.

The caption for the vertical slider demo in the IE documentation erroneously indicates that setting height greater than width will display a range slider vertically, but this does not work. In the code section, it plainly does not set height or width, and instead uses writing-mode. The writing-mode property, as implemented by IE, is very robust. Sadly, the values defined in the current working draft of the spec as of this writing, are much more limited. Should future versions of IE drop support of bt-lr in favor of the currently proposed vertical-lr (which would be the equivalent of tb-lr), the slider would display upside down. Most likely, future versions would extend the writing-mode to accept new values rather than drop support for existing values. But, it's good to know what you are dealing with.

EDIT (2014/04): It now has a Qt GUI to analyze snapshots.

Many answers using external programs, which is not really using Bash.

If you know you will have Bash4 available you should really just use the ${VAR,,} notation (it is easy and cool). For Bash before 4 (My Mac still uses Bash 3.2 for example). I used the corrected version of @ghostdog74 's answer to create a more portable version.

One you can call lowercase 'my STRING' and get a lowercase version. I read comments about setting the result to a var, but that is not really portable in Bash, since we can't return strings. Printing it is the best solution. Easy to capture with something like var="$(lowercase $str)".

How this works

The way this works is by getting the ASCII integer representation of each char with printf and then adding 32 if upper-to->lower, or subtracting 32 if lower-to->upper. Then use printf again to convert the number back to a char. From 'A' -to-> 'a' we have a difference of 32 chars.

Using printf to explain:

$ printf "%d\n" "'a"
97
$ printf "%d\n" "'A"
65

97 - 65 = 32

And this is the working version with examples.
Please note the comments in the code, as they explain a lot of stuff:

#!/bin/bash

# lowerupper.sh

# Prints the lowercase version of a char
lowercaseChar(){
    case "$1" in
        [A-Z])
            n=$(printf "%d" "'$1")
            n=$((n+32))
            printf \\$(printf "%o" "$n")
            ;;
        *)
            printf "%s" "$1"
            ;;
    esac
}

# Prints the lowercase version of a sequence of strings
lowercase() {
    word="$@"
    for((i=0;i<${#word};i++)); do
        ch="${word:$i:1}"
        lowercaseChar "$ch"
    done
}

# Prints the uppercase version of a char
uppercaseChar(){
    case "$1" in
        [a-z])
            n=$(printf "%d" "'$1")
            n=$((n-32))
            printf \\$(printf "%o" "$n")
            ;;
        *)
            printf "%s" "$1"
            ;;
    esac
}

# Prints the uppercase version of a sequence of strings
uppercase() {
    word="$@"
    for((i=0;i<${#word};i++)); do
        ch="${word:$i:1}"
        uppercaseChar "$ch"
    done
}

# The functions will not add a new line, so use echo or
# append it if you want a new line after printing

# Printing stuff directly
lowercase "I AM the Walrus!"$'\n'
uppercase "I AM the Walrus!"$'\n'

echo "----------"

# Printing a var
str="A StRing WITH mixed sTUFF!"
lowercase "$str"$'\n'
uppercase "$str"$'\n'

echo "----------"

# Not quoting the var should also work, 
# since we use "$@" inside the functions
lowercase $str$'\n'
uppercase $str$'\n'

echo "----------"

# Assigning to a var
myLowerVar="$(lowercase $str)"
myUpperVar="$(uppercase $str)"
echo "myLowerVar: $myLowerVar"
echo "myUpperVar: $myUpperVar"

echo "----------"

# You can even do stuff like
if [[ 'option 2' = "$(lowercase 'OPTION 2')" ]]; then
    echo "Fine! All the same!"
else
    echo "Ops! Not the same!"
fi

exit 0

And the results after running this:

$ ./lowerupper.sh 
i am the walrus!
I AM THE WALRUS!
----------
a string with mixed stuff!
A STRING WITH MIXED STUFF!
----------
a string with mixed stuff!
A STRING WITH MIXED STUFF!
----------
myLowerVar: a string with mixed stuff!
myUpperVar: A STRING WITH MIXED STUFF!
----------
Fine! All the same!

This should only work for ASCII characters though.

For me it is fine, since I know I will only pass ASCII chars to it.
I am using this for some case-insensitive CLI options, for example.

Yes, always will be slower create an object by reflection because the JVM cannot optimize the code on compilation time. See the Sun/Java Reflection tutorials for more details.

See this simple test:

public class TestSpeed {
    public static void main(String[] args) {
        long startTime = System.nanoTime();
        Object instance = new TestSpeed();
        long endTime = System.nanoTime();
        System.out.println(endTime - startTime + "ns");

        startTime = System.nanoTime();
        try {
            Object reflectionInstance = Class.forName("TestSpeed").newInstance();
        } catch (InstantiationException e) {
            e.printStackTrace();
        } catch (IllegalAccessException e) {
            e.printStackTrace();
        } catch (ClassNotFoundException e) {
            e.printStackTrace();
        }
        endTime = System.nanoTime();
        System.out.println(endTime - startTime + "ns");
    }
}

Here is a rough explanation of the concepts.

[ACK] is the acknowledgement that the previously sent data packet was received.

[FIN] is sent by a host when it wants to terminate the connection; the TCP protocol requires both endpoints to send the termination request (i.e. FIN).

So, suppose

• host A sends a data packet to host B
• and then host B wants to close the connection.
• Host B (depending on timing) can respond with [FIN,ACK] indicating that it received the sent packet and wants to close the session.
• Host A should then respond with a [FIN,ACK] indicating that it received the termination request (the ACK part) and that it too will close the connection (the FIN part).

However, if host A wants to close the session after sending the packet, it would only send a [FIN] packet (nothing to acknowledge) but host B would respond with [FIN,ACK] (acknowledges the request and responds with FIN).

Finally, some TCP stacks perform half-duplex termination, meaning that they can send [RST] instead of the usual [FIN,ACK]. This happens when the host actively closes the session without processing all the data that was sent to it. Linux is one operating system which does just this.

You can find a more detailed and comprehensive explanation here.

In my case the targetPath was not having any value it was blank in the resources --> resource for the file directory with files that had issue. I had to update it to global as seen in the Code Sample 2 and re-run build to fix the issue.

Code Sample 1 (with issue)

<build>
    <resources>
        <resource>
            <directory>src/main/locale</directory>
            <filtering>true</filtering>
            <targetPath></targetPath>
            <includes>
                <include>*.xml</include>
                <include>*.config</include>
                <include>*.properties</include>
            </includes>
        </resource>
    </resources>

Code Sample 2 (fix applied)

<build>
    <resources>
        <resource>
            <directory>src/main/locale</directory>
            <filtering>true</filtering>
            <targetPath>global</targetPath>
            <includes>
                <include>*.xml</include>
                <include>*.config</include>
                <include>*.properties</include>
            </includes>
        </resource>
    </resources>

My first contribution to the site. Also, according to the tests that I have done, this code runs faster than all the other methods mentioned here before this date, of course it is minimal if there are few values, but the time increases exponentially when adding too many.

var result = permutations([1,2,3,4]);

var output = window.document.getElementById('output');
output.innerHTML = JSON.stringify(result);

function permutations(arr) {
    var finalArr = [];
    function iterator(arrayTaken, tree) {
        var temp;
        for (var i = 0; i < tree; i++) {
            temp = arrayTaken.slice();
            temp.splice(tree - 1 - i, 0, temp.splice(tree - 1, 1)[0]);
            if (tree >= arr.length) {
                finalArr.push(temp);
            } else {
                iterator(temp, tree + 1);
            }
        }
    }
    iterator(arr, 1);
    return finalArr;
};

<div id="output"></div>

I think process.communicate() would be suitable for output having small size. For larger output it would not be the best approach.

require is part of the Asynchronous Module Definition (AMD) API.

A browser implementation can be found via require.js and native support can be found in node.js.

The documentation for the library you are using should tell you what you need to use it, I suspect that it is intended to run under Node.js and not in browsers.

In my opinion should the alt text always describe what is visible in the picture, for the case that the image is not displayed.

alt = text [CS] For user agents that cannot display images, forms, or applets, this attribute specifies alternate text. The language of the alternate text is specified by the lang attribute.

There's a good topic about this in Stack Overflow question Is 'yield return' slower than "old school" return?.

It says:

ReadAllLines loads all of the lines into memory and returns a string[]. All well and good if the file is small. If the file is larger than will fit in memory, you'll run out of memory.

ReadLines, on the other hand, uses yield return to return one line at a time. With it, you can read any size file. It doesn't load the whole file into memory.

Say you wanted to find the first line that contains the word "foo", and then exit. Using ReadAllLines, you'd have to read the entire file into memory, even if "foo" occurs on the first line. With ReadLines, you only read one line. Which one would be faster?

Just stick with the virtual machine: If you're running Internet Explorer 8 you'll be able to activate the developer window using F12. There you're able to edit CSS as well as HTML on the fly without saving/reloading the page.

I had the same error. I found the solution for problem now. The problem was client program was finishing before server read the streams.

In my case it was best to calculate this in SQL Server, since i wanted to take current location and then search for all zip codes within a certain distance from current location. I also had a DB which contained a list of zip codes and their lat longs. Cheers

$user->data is an array of objects. Each element in the array has a name and value property (as well as others).

Try putting the 2nd foreach inside the 1st.

foreach($user->data as $mydata)
{
    echo $mydata->name . "\n";
    foreach($mydata->values as $values)
    {
        echo $values->value . "\n";
    }
}

To find all configurations, you just write this command:

git config --list

In my local i run this command .

You can try this code. Fast, you can also include special characters

@echo off
set "str=[string]"
echo %str% > "%tmp%\STR"
for %%P in ("%TMP%\STR") do (set /a strlen=%%~zP-3)
echo String lenght: %strlen%

I felt like replying as well, explaining the same thing as the others a bit differently. I am sure you know most of this, but it might help someone else.

<a href="#" class="view">

The

href="#"

part is a commonly used way to make sure the link doesn't lead anywhere on it's own. the #-attribute is used to create a link to some other section in the same document. For example clicking a link of this kind:

<a href="#news">Go to news</a>

will take you to wherever you have the

<a name="news"></a>

code. So if you specify # without any name like in your case, the link leads nowhere.

The

class="view"

part gives it an identifier that CSS or javascript can use. Inside the CSS-files (if you have any) you will find specific styling procedures on all the elements tagged with the "view"-class.

To find out where the URL is specified I would look in the javascript code. It is either written directly in the same document or included from another file.

Search your source code for something like:

<script type="text/javascript"> bla bla bla </script>

or

<script> bla bla bla </script>

and then search for any reference to your "view"-class. An included javascript file can look something like this:

<script type="text/javascript" src="include/javascript.js"></script>

In that case, open javascript.js under the "include" folder and search in that file. Most commonly the includes are placed between <head> and </head> or close to the </body>-tag.

A faster way to find the link is to search for the actual link it goes to. For example, if you are directed to http://www.google.com/search?q=html when you click it, search for "google.com" or something in all the files you have in your web project, just remember the included files.

In many text editors you can open all the files at once, and then search in them all for something.

My site configuration file is example.conf in sites-available folder So you can create a symbolic link as

ln -s /etc/nginx/sites-available/example.conf /etc/nginx/sites-enabled/

Consider using <span> to isolate small segments of markup to be styled without breaking up layout. This would seem to be more idiomatic than trying to force a <div> not to display itself--if in fact the checkbox itself cannot be styled in the way you want.

First, to convert a Categorical column to its numerical codes, you can do this easier with: dataframe['c'].cat.codes.
Further, it is possible to select automatically all columns with a certain dtype in a dataframe using select_dtypes. This way, you can apply above operation on multiple and automatically selected columns.

First making an example dataframe:

In [75]: df = pd.DataFrame({'col1':[1,2,3,4,5], 'col2':list('abcab'),  'col3':list('ababb')})

In [76]: df['col2'] = df['col2'].astype('category')

In [77]: df['col3'] = df['col3'].astype('category')

In [78]: df.dtypes
Out[78]:
col1       int64
col2    category
col3    category
dtype: object

Then by using select_dtypes to select the columns, and then applying .cat.codes on each of these columns, you can get the following result:

In [80]: cat_columns = df.select_dtypes(['category']).columns

In [81]: cat_columns
Out[81]: Index([u'col2', u'col3'], dtype='object')

In [83]: df[cat_columns] = df[cat_columns].apply(lambda x: x.cat.codes)

In [84]: df
Out[84]:
   col1  col2  col3
0     1     0     0
1     2     1     1
2     3     2     0
3     4     0     1
4     5     1     1

This worked for me.

• Write the formula in the first cell.
• Click Enter.
• Click on the first cell and press Ctrl + Shift + down_arrow. This will select the last cell in the column used on the worksheet.
• Ctrl + D. This will fill copy the formula in the remaining cells.

Just create a new branch:

git checkout -b newBranch

And if you do git status you'll see that the state of the code hasn't changed and you can commit it to the new branch.

I build a few projects for SharePoint and, of course, deployed them. One time it happened.

I found an old assembly in C:\Windows\assembly\temp\xxx (with FarManager), removed it after reboot, and all projects built.

I have question for MSBuild, because in project assemblies linked like projects and every assembly is marked "Copy local", but not from the GAC.

I have used Newtonsoft JSON.NET (Documentation) It allows you to create a class / object, populate the fields, and serialize as JSON.

public class ReturnData 
{
    public int totalCount { get; set; }
    public List<ExceptionReport> reports { get; set; }  
}

public class ExceptionReport
{
    public int reportId { get; set; }
    public string message { get; set; }  
}


string json = JsonConvert.SerializeObject(myReturnData);

You can try these:

Dim valueStr as String = "10"

Dim valueIntConverted as Integer = CInt(valueStr)

Another example:

Dim newValueConverted as Integer = Val("100")

Edit: The answer marked as "correct" is not correct.

It's easy to do. Try this code, swapping out "ie.jpg" with whatever picture you have handy:

<!DOCTYPE HTML>
<html>
    <head>
        <script>
            var canvas;
            var context;
            var ga = 0.0;
            var timerId = 0;
            
            function init()
            {
                canvas = document.getElementById("myCanvas");
                context = canvas.getContext("2d");
                timerId = setInterval("fadeIn()", 100);
            }
            
            function fadeIn()
            {
                context.clearRect(0,0, canvas.width,canvas.height);
                context.globalAlpha = ga;
                var ie = new Image();
                ie.onload = function()
                {
                    context.drawImage(ie, 0, 0, 100, 100);
                };
                ie.src = "ie.jpg";
                
                ga = ga + 0.1;
                if (ga > 1.0)
                {
                    goingUp = false;
                    clearInterval(timerId);
                }
            }
        </script>
    </head>
    <body onload="init()">
        <canvas height="200" width="300" id="myCanvas"></canvas>
    </body>
</html>

The key is the globalAlpha property.

Tested with IE 9, FF 5, Safari 5, and Chrome 12 on Win7.

Generally when I want to create a JSON or YAML string, I start out by building the Perl data structure, and then running a simple conversion on it. You could put a UI in front of the Perl data structure generation, e.g. a web form.

Converting a structure to JSON is very straightforward:

use strict;
use warnings;
use JSON::Any;

my $data = { arbitrary structure in here };
my $json_handler = JSON::Any->new(utf8=>1);
my $json_string = $json_handler->objToJson($data);

var myArray = new Array();
myArray['one'] = 1;
myArray['two'] = 2;
myArray['three'] = 3;

// Show the values stored
for (var i in myArray) {
    alert('key is: ' + i + ', value is: ' + myArray[i]);
}

This is ok, but it iterates through every property of the array object.

If you want to only iterate through the properties myArray.one, myArray.two... you try like this:

myArray['one'] = 1;
myArray['two'] = 2;
myArray['three'] = 3;
myArray.push("one");
myArray.push("two");
myArray.push("three");
for(var i=0;i<maArray.length;i++){
    console.log(myArray[myArray[i]])
}

Now you can access both by myArray["one"] and iterate only through these properties.

There is no block comment in VB.NET.

You need to use a ' in front of every line you want to comment out.

In Visual Studio you can use the keyboard shortcuts that will comment/uncomment the selected lines for you:

Ctrl + K, C to comment

Ctrl + K, U to uncomment

This will give you a list of a single group, and the members of each group.

param
(   
    [Parameter(Mandatory=$true,position=0)]
    [String]$GroupName
)

import-module activedirectory

# optional, add a wild card..
# $groups = $groups + "*"

$Groups = Get-ADGroup -filter {Name -like $GroupName} | Select-Object Name

ForEach ($Group in $Groups)
   {write-host " "
    write-host "$($group.name)"
    write-host "----------------------------"

    Get-ADGroupMember -identity $($groupname) -recursive | Select-Object samaccountname

 }
write-host "Export Complete"

If you want the friendly name, or other details, add them to the end of the select-object query.

ECMAScript 6 solution:

var params = window.location.search
  .substring(1)
  .split("&")
  .map(v => v.split("="))
  .reduce((map, [key, value]) => map.set(key, decodeURIComponent(value)), new Map())

We can change context root path using a simple entry in the properties file.

application.properties

### Spring boot 1.x #########
server.contextPath=/ClientApp

### Spring boot 2.x #########
server.servlet.context-path=/ClientApp

According to the MSDN documentation here, The basename argument specifies "The root name of the resource file without its extension but including any fully qualified namespace name. For example, the root name for the resource file named "MyApplication.MyResource.en-US.resources" is "MyApplication.MyResource"."

The ResourceManager will automatically try to retrieve the values for the current UI culture. If you want to use a specific language, you'll need to set the current UI culture to the language you wish to use.

These are the necersary imports:

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;

And this is a method that will allow you to read from a File by passing it the filename as a parameter like this: readFile("yourFile.txt");

String readFile(String fileName) throws IOException {
    BufferedReader br = new BufferedReader(new FileReader(fileName));
    try {
        StringBuilder sb = new StringBuilder();
        String line = br.readLine();

        while (line != null) {
            sb.append(line);
            sb.append("\n");
            line = br.readLine();
        }
        return sb.toString();
    } finally {
        br.close();
    }
}

This worked for me:

$("[id*=txtName]").on('keydown', function(e) { var keyCode = e.keyCode || e.which; if (keyCode == 9) { e.preventDefault(); alert('Tab Pressed'); } });

Since you mentioned that you want to re-add the options later, I would suggest that you load an array or object with the contents of the select box on page load - that way you always have a "master list" of the original select if you need to restore it.

I made a simple example that removes the first element in the select and then a restore button puts the select box back to it's original state:

http://jsfiddle.net/CZcvM/

Path.GetFileName( Request.Url.AbsolutePath )

you can use LocalRegistry such as:

Registry rgsty = LocateRegistry.createRegistry(1888);
rgsty.rebind("hello", hello);

The following test works in Chrome 16 (dev branch) on X86 and Chrome 15 on Mac OSX Lion

http://html5-demos.appspot.com/static/fullscreen.html

Go to phpMyAdmin > config.inc.php > $cfg['Servers'][$i]['password'] = '';

You want your if check to be:

{% if not loop.last %}
    ,
{% endif %}

Note that you can also shorten the code by using If Expression:

{{ ", " if not loop.last else "" }}

SVN is one repo and lots of clients. Git is a repo with lots of client repos, each with a user. It's decentralised to a point where people can track their own edits locally without having to push things to an external server.

SVN is designed to be more central where Git is based on each user having their own Git repo and those repos push changes back up into a central one. For that reason, Git gives individuals better local version control.

Meanwhile you have the choice between TortoiseGit, GitExtensions (and if you host your "central" git-repository on github, their own client – GitHub for Windows).

If you're looking on getting out of SVN, you might want to evaluate Bazaar for a bit. It's one of the next generation of version control systems that have this distributed element. It isn't POSIX dependant like git so there are native Windows builds and it has some powerful open source brands backing it.

But you might not even need these sorts of features yet. Have a look at the features, advantages and disadvantages of the distributed VCSes. If you need more than SVN offers, consider one. If you don't, you might want to stick with SVN's (currently) superior desktop integration.

The bootstrap 3 docs for horizontal forms let you use the .form-horizontal class to make your form labels and inputs vertically aligned. The structure for these forms is:

<form class="form-horizontal" role="form">
  <div class="form-group">
    <label for="input1" class="col-lg-2 control-label">Label1</label>
    <div class="col-lg-10">
      <input type="text" class="form-control" id="input1" placeholder="Input1">
    </div>
  </div>
  <div class="form-group">
    <label for="input2" class="col-lg-2 control-label">Label2</label>
    <div class="col-lg-10">
      <input type="password" class="form-control" id="input2" placeholder="Input2">
    </div>
  </div>
</form>

Therefore, your form should look like this:

<form class="form-horizontal" role="form">
    <div class="form-group">
        <div class="col-xs-3">
            <label for="class_type"><h2><span class=" label label-primary">Class Type</span></h2></label>
        </div>
        <div class="col-xs-2">
            <select id="class_type" class="form-control input-lg" autocomplete="off">
                <option>Economy</option>
                <option>Premium Economy</option>
                <option>Club World</option>
                <option>First Class</option>
            </select>
        </div>
    </div>
</form>

I found that I could access the checkbox directly using Worksheets("SheetName").CB_Checkboxname.value directly without relating to additional objects.

When installing Python 3.4 the "Add python.exe to Path" came up unselected. Re-installed with this selected and problem resolved.

Make an empty new branch like this:

true | git mktree | xargs git commit-tree | xargs git branch proj-doc

If your proj-doc files are already in a commit under a single subdir you can make the new branch this way:

git commit-tree thatcommit:path/to/dir | xargs git branch proj-doc

which might be more convenient than git branch --orphan if that would leave you with a lot of git rm and git mving to do.

Try

git branch --set-upstream proj-doc origin/proj-doc

and see if that helps with your fetching-too-much problem. Also if you really only want to fetch a single branch it's safest to just specify it on the commandline.

You need to set option CURLOPT_PROXYTYPE to CURLPROXY_SOCKS5_HOSTNAME, which sadly wasn't defined in old PHP versions, circa pre-5.6; if you have earlier in but you can explicitly use its value, which is equal to 7:

curl_setopt($ch, CURLOPT_PROXYTYPE, 7);

Yet another approach - just set a flag on an element signaling which type of event should be handled:

function setRangeValueChangeHandler(rangeElement, handler) {
    rangeElement.oninput = (event) => {
        handler(event);
        // Save flag that we are using onInput in current browser
        event.target.onInputHasBeenCalled = true;
    };

    rangeElement.onchange = (event) => {
        // Call only if we are not using onInput in current browser
        if (!event.target.onInputHasBeenCalled) {
            handler(event);
        }
    };
}

To add something to this (cause I found it while searching on this problem, and my solution involved slightly more)...

If you don't have a "Browse with..." option for .aspx files (as I didn't in a MVC application), the easiest solution is to add a dummy HTML file, and right-click it to set the option as described in the answer. You can remove the file afterward.

The option is actually set in: C:\Documents and Settings[user]\Local Settings\Application Data\Microsoft\VisualStudio[version]\browser.xml

However, if you modify the file directly while VS is running, VS will overwrite it with your previous option on next run. Also, if you edit the default in VS you won't have to worry about getting the schema right, so the work-around dummy file is probably the easiest way.

I open a modal after a modal and fact the error on modal scrolling, and this css solved my problem:

.modal {
    overflow-y: auto;
    padding-right: 15px;
}

By using jot:

jot -w "http://example.com/%d.jpg" 1000 1

You can use the YouTube JavaScript player API, which has a feature on its own to set playback quality.

player.setPlaybackQuality(suggestedQuality:String):Void

This function sets the suggested video quality for the current video. The function causes the video to reload at its current position in the new quality. If the playback quality does change, it will only change for the video being played. Calling this function does not guarantee that the playback quality will actually change. However, if the playback quality does change, the onPlaybackQualityChange event will fire, and your code should respond to the event rather than the fact that it called the setPlaybackQuality function. [source]

if there is one error in the the submit function,the submit function will be execute. in other sentences prevent default(or return false) does not work when one error exist in submit function.

If you authenticate your clients with Oauth2 I think you will need underscore for at least two of your parameter names:

• client_id
• client_secret

I have used camelCase in my (not yet published) REST API. While writing the API documentation I have been thinking of changing everything to snake_case so I don't have to explain why the Oauth params are snake_case while other params are not.

See: https://tools.ietf.org/html/rfc6749

Anyway you need 'Year'.

In some engineering fields, you have fixed day and month and year can be variable. But that day and month are important for beginning calculation without considering which year you are. Your user, for example, only should select a day and a month and providing year is up to you.

You can create a custom combobox using this: Customizable ComboBox Drop-Down.

1- In VS create a user control.

2- See the code in the link above for impelemnting that control.

3- Create another user control and place in it 31 button or label and above them place a label to show months.

4- Place the control in step 3 in your custom combobox.

5- Place the control in setp 4 in step 1.

You now have a control with only days and months. You can use any year that you have in your database or ....

I was having the same issue, and my limitation was that i cannot have a predefined width. If your element does not have a fixed width, then try this

div#thing 
{ 
  position: absolute; 
  top: 0px; 
  z-index: 2; 
  left:0;
  right:0;
 }

div#thing-body
{
  text-align:center;
}

then modify your html to look like this

<div id="thing">
 <div id="thing-child">
  <p>text text text with no fixed size, variable font</p>
 </div>
</div>

I would typically do something like this (onblur), but it could be attached to any of the events:

Angular 4+

I've created a generic directive, able to receive any mask and also able to define the mask dynamically based on the value:

mask.directive.ts:

import { Directive, EventEmitter, HostListener, Input, Output } from '@angular/core';
import { NgControl } from '@angular/forms';

import { MaskGenerator } from '../interfaces/mask-generator.interface';

@Directive({
    selector: '[spMask]' 
})
export class MaskDirective {

    private static readonly ALPHA = 'A';
    private static readonly NUMERIC = '9';
    private static readonly ALPHANUMERIC = '?';
    private static readonly REGEX_MAP = new Map([
        [MaskDirective.ALPHA, /\w/],
        [MaskDirective.NUMERIC, /\d/],
        [MaskDirective.ALPHANUMERIC, /\w|\d/],
    ]);

    private value: string = null;
    private displayValue: string = null;

    @Input('spMask') 
    public maskGenerator: MaskGenerator;

    @Input('spKeepMask') 
    public keepMask: boolean;

    @Input('spMaskValue') 
    public set maskValue(value: string) {
        if (value !== this.value) {
            this.value = value;
            this.defineValue();
        }
    };

    @Output('spMaskValueChange') 
    public changeEmitter = new EventEmitter<string>();

    @HostListener('input', ['$event'])
    public onInput(event: { target: { value?: string }}): void {
        let target = event.target;
        let value = target.value;
        this.onValueChange(value);
    }

    constructor(private ngControl: NgControl) { }

    private updateValue(value: string) {
        this.value = value;
        this.changeEmitter.emit(value);
        MaskDirective.delay().then(
            () => this.ngControl.control.updateValueAndValidity()
        );
    }

    private defineValue() {
        let value: string = this.value;
        let displayValue: string = null;

        if (this.maskGenerator) {
            let mask = this.maskGenerator.generateMask(value);

            if (value != null) {
                displayValue = MaskDirective.mask(value, mask);
                value = MaskDirective.processValue(displayValue, mask, this.keepMask);
            }   
        } else {
            displayValue = this.value;
        }

        MaskDirective.delay().then(() => {
            if (this.displayValue !== displayValue) {
                this.displayValue = displayValue;
                this.ngControl.control.setValue(displayValue);
                return MaskDirective.delay();
            }
        }).then(() => {
            if (value != this.value) {
                return this.updateValue(value);
            }
        });
    }

    private onValueChange(newValue: string) {
        if (newValue !== this.displayValue) {
            let displayValue = newValue;
            let value = newValue;

            if ((newValue == null) || (newValue.trim() === '')) {
                value = null;
            } else if (this.maskGenerator) {
                let mask = this.maskGenerator.generateMask(newValue);
                displayValue = MaskDirective.mask(newValue, mask);
                value = MaskDirective.processValue(displayValue, mask, this.keepMask);
            }

            this.displayValue = displayValue;

            if (newValue !== displayValue) {
                this.ngControl.control.setValue(displayValue);
            }

            if (value !== this.value) {
                this.updateValue(value);
            }
        }
    }

    private static processValue(displayValue: string, mask: string, keepMask: boolean) {
        let value = keepMask ? displayValue : MaskDirective.unmask(displayValue, mask);
        return value
    }

    private static mask(value: string, mask: string): string {
        value = value.toString();

        let len = value.length;
        let maskLen = mask.length;
        let pos = 0;
        let newValue = '';

        for (let i = 0; i < Math.min(len, maskLen); i++) {
            let maskChar = mask.charAt(i);
            let newChar = value.charAt(pos);
            let regex: RegExp = MaskDirective.REGEX_MAP.get(maskChar);

            if (regex) {
                pos++;

                if (regex.test(newChar)) {
                    newValue += newChar;
                } else {
                    i--;
                    len--;
                }
            } else {
                if (maskChar === newChar) {
                    pos++;
                } else {
                    len++;
                }

                newValue += maskChar;
            }
        }       

        return newValue;
    }

    private static unmask(maskedValue: string, mask: string): string {
        let maskLen = (mask && mask.length) || 0;
        return maskedValue.split('').filter(
            (currChar, idx) => (idx < maskLen) && MaskDirective.REGEX_MAP.has(mask[idx])
        ).join('');
    }

    private static delay(ms: number = 0): Promise<void> {
        return new Promise(resolve => setTimeout(() => resolve(), ms)).then(() => null);
    }
}

(Remember to declare it in your NgModule)

The numeric character in the mask is 9 so your mask would be (999) 999-9999. You can change the NUMERIC static field if you want (if you change it to 0, your mask should be (000) 000-0000, for example).

The value is displayed with mask but stored in the component field without mask (this is the desirable behaviour in my case). You can make it be stored with mask using [spKeepMask]="true".

The directive receives an object that implements the MaskGenerator interface.

mask-generator.interface.ts:

export interface MaskGenerator {
    generateMask: (value: string) => string;
}

This way it's possible to define the mask dynamically based on the value (like credit cards).

I've created an utilitarian class to store the masks, but you can specify it directly in your component too.

my-mask.util.ts:

export class MyMaskUtil {

    private static PHONE_SMALL = '(999) 999-9999';
    private static PHONE_BIG = '(999) 9999-9999';
    private static CPF = '999.999.999-99';
    private static CNPJ = '99.999.999/9999-99';

    public static PHONE_MASK_GENERATOR: MaskGenerator = {
        generateMask: () =>  MyMaskUtil.PHONE_SMALL,
    }

    public static DYNAMIC_PHONE_MASK_GENERATOR: MaskGenerator = {
        generateMask: (value: string) => {
            return MyMaskUtil.hasMoreDigits(value, MyMaskUtil.PHONE_SMALL) ? 
                MyMaskUtil.PHONE_BIG : 
                MyMaskUtil.PHONE_SMALL;
        },
    }

    public static CPF_MASK_GENERATOR: MaskGenerator = {
        generateMask: () => MyMaskUtil.CPF,
    }

    public static CNPJ_MASK_GENERATOR: MaskGenerator = {
        generateMask: () => MyMaskUtil.CNPJ,
    }

    public static PERSON_MASK_GENERATOR: MaskGenerator = {
        generateMask: (value: string) => {
            return MyMaskUtil.hasMoreDigits(value, MyMaskUtil.CPF) ? 
                MyMaskUtil.CNPJ : 
                MyMaskUtil.CPF;
        },
    }

    private static hasMoreDigits(v01: string, v02: string): boolean {
        let d01 = this.onlyDigits(v01);
        let d02 = this.onlyDigits(v02);
        let len01 = (d01 && d01.length) || 0;
        let len02 = (d02 && d02.length) || 0;
        let moreDigits = (len01 > len02);
        return moreDigits;      
    }

    private static onlyDigits(value: string): string {
        let onlyDigits = (value != null) ? value.replace(/\D/g, '') : null;
        return onlyDigits;      
    }
}

Then you can use it in your component (use spMaskValue instead of ngModel, but if is not a reactive form, use ngModel with nothing, like in the example below, just so that you won't receive an error of no provider because of the injected NgControl in the directive; in reactive forms you don't need to include ngModel):

my.component.ts:

@Component({ ... })
export class MyComponent {
    public phoneValue01: string = '1231234567';
    public phoneValue02: string;
    public phoneMask01 = MyMaskUtil.PHONE_MASK_GENERATOR;
    public phoneMask02 = MyMaskUtil.DYNAMIC_PHONE_MASK_GENERATOR;
}

my.component.html:

<span>Phone 01 ({{ phoneValue01 }}):</span><br>
<input type="text" [(spMaskValue)]="phoneValue01" [spMask]="phoneMask01" ngModel>
<br><br>
<span>Phone 02 ({{ phoneValue02 }}):</span><br>
<input type="text" [(spMaskValue)]="phoneValue02" [spMask]="phoneMask02" [spKeepMask]="true" ngModel>

(Take a look at phone02 and see that when you type 1 more digit, the mask changes; also, look that the value stored of phone01 is without mask)

I've tested it with normal inputs as well as with ionic inputs (ion-input), with both reactive (with formControlName, not with formControl) and non-reactive forms.

Whenever there are issues of mismatched axis limits, the right tool in base graphics is to use matplot. The key is to leverage the from and to arguments to density.default. It's a bit hackish, but fairly straightforward to roll yourself:

set.seed(102349)
x1 = rnorm(1000, mean = 5, sd = 3)
x2 = rnorm(5000, mean = 2, sd = 8)

xrng = range(x1, x2)

#force the x values at which density is
#  evaluated to be the same between 'density'
#  calls by specifying 'from' and 'to'
#  (and possibly 'n', if you'd like)
kde1 = density(x1, from = xrng[1L], to = xrng[2L])
kde2 = density(x2, from = xrng[1L], to = xrng[2L])

matplot(kde1$x, cbind(kde1$y, kde2$y))

Add bells and whistles as desired (matplot accepts all the standard plot/par arguments, e.g. lty, type, col, lwd, ...).

This helped me:

<p>Date/Time: <span id="datetime"></span></p><script>var dt = new Date();
document.getElementById("datetime").innerHTML=dt.toLocaleString();</script>    

There is no built-in way that I know of to do this so you will need to come up with a custom solution depending on how complicated your form is. You should read this post:

Convert HTML forms to read-only (Update: broken post link, archived link)

EDIT: Based on your update, why are you so worried about having it read-only? You can do it via client-side but if not you will have to add the required tag to each control or convert the data and display it as raw text with no controls. If you are trying to make it read-only so that the next post will be unmodified then you have a problem because anyone can mess with the post to produce whatever they want so when you do in fact finally receive the data you better be checking it again to make sure it is valid.

So let's say after getMasterData servlet will response.sendRedirect to to test.jsp.

In test.jsp

Create a javascript

<script type="text/javascript">
function alertName(){
alert("Form has been submitted");
} 
</script> 

and than at the bottom

<script type="text/javascript"> window.onload = alertName; </script>

Note:im not sure how to type the code in stackoverflow!. Edit: I just learned how to

Edit 2: TO the question:This works perfectly. Another question. How would I get rid of the initial alert when I first start up the JSP? "Form has been submitted" is present the second I execute. It shows up after the load is done to which is perfect.

To do that i would highly recommendation to use session!

So what you want to do is in your servlet:

session.setAttribute("getAlert", "Yes");//Just initialize a random variable.
response.sendRedirect(test.jsp);

than in the test.jsp

<%
session.setMaxInactiveInterval(2);
%>

 <script type="text/javascript">
var Msg ='<%=session.getAttribute("getAlert")%>';
    if (Msg != "null") {
 function alertName(){
 alert("Form has been submitted");
 } 
 }
 </script> 

and than at the bottom

<script type="text/javascript"> window.onload = alertName; </script>

So everytime you submit that form a session will be pass on! If session is not null the function will run!

mentioned also here, you can use this:

import collections
Point = collections.namedtuple('Point', ['x', 'y'])
p = Point(1, y=2)
>>> p.x, p.y
1 2
>>> p[0], p[1]
1 2

Worth noting that the code you see is sent to the database as is, the queries are sent separately to prevent SQL injection. AFAIK The ? marks are placeholders that are replaced by the number params by the database, not by hibernate.

They say it right there in the documentation for the FPDF constructor:

FPDF([string orientation [, string unit [, mixed size]]])

This is the class constructor. It allows to set up the page size, the orientation and the unit of measure used in all methods (except for font sizes). Parameters ...

size

The size used for pages. It can be either one of the following values (case insensitive):

A3 A4 A5 Letter Legal

or an array containing the width and the height (expressed in the unit given by unit).

They even give an example with custom size:

Example with a custom 100x150 mm page size:

$pdf = new FPDF('P','mm',array(100,150));

Another issue i faced with was, ssh.exe was not looking at the %userprofile%/.ssh folder for the key files. Instead it was looking to the folder C:\Program Files (x86)\Git\.ssh which was empty and which causes a hang due to ssh authentication prompt on the machine where git repo located.

We just copied the key files under %userprofile%/.ssh to C:\Program Files (x86)\Git\.ssh and the problem is resolved.

You can create table script along with its data using following steps:

1. Right click on the database.
2. Select Tasks > Generate scripts ...
3. Click next.
4. Click next.
5. In Table/View Options, set Script Data to True; then click next.
6. Select the Tables checkbox and click next.
7. Select your table name and click next.
8. Click next until the wizard is done.

For more information, see Eric Johnson's blog.

Here is shortest way of doing it.

$userRecord = Model::where(['email'=>$email, 'password'=>$password])->first();

On the contrary, I do think working with list makes it easy to automate such things.

Here is one solution (I stored your four dataframes in folder temp/).

filenames <- list.files("temp", pattern="*.csv", full.names=TRUE)
ldf <- lapply(filenames, read.csv)
res <- lapply(ldf, summary)
names(res) <- substr(filenames, 6, 30)

It is important to store the full path for your files (as I did with full.names), otherwise you have to paste the working directory, e.g.

filenames <- list.files("temp", pattern="*.csv")
paste("temp", filenames, sep="/")

will work too. Note that I used substr to extract file names while discarding full path.

You can access your summary tables as follows:

> res$`df4.csv`
       A              B        
 Min.   :0.00   Min.   : 1.00  
 1st Qu.:1.25   1st Qu.: 2.25  
 Median :3.00   Median : 6.00  
 Mean   :3.50   Mean   : 7.00  
 3rd Qu.:5.50   3rd Qu.:10.50  
 Max.   :8.00   Max.   :16.00  

If you really want to get individual summary tables, you can extract them afterwards. E.g.,

for (i in 1:length(res))
  assign(paste(paste("df", i, sep=""), "summary", sep="."), res[[i]])

Extending your code (assuming that the XML you want to send is in xmlString) :

String xmlString = "</xml>";
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpRequest = new HttpPost(this.url);
httpRequest.setHeader("Content-Type", "application/xml");
StringEntity xmlEntity = new StringEntity(xmlString);
httpRequest.setEntity(xmlEntity );
HttpResponse httpresponse = httpclient.execute(httppost);

Got stuck on that too...

Finally managed to set the icon i wanted using the following code:

from tkinter import *
root.tk.call('wm', 'iconphoto', root._w, PhotoImage(file='resources/icon.png'))

$users = $dbh->query($sql);
foreach ($users as $row) {
    print $row["name"] . "-" . $row["sex"] ."<br/>";
}
foreach ($users as $row) {
    print $row["name"] . "-" . $row["sex"] ."<br/>";
}

Here $users is a PDOStatement object over which you can iterate. The first iteration outputs all results, the second does nothing since you can only iterate over the result once. That's because the data is being streamed from the database and iterating over the result with foreach is essentially shorthand for:

while ($row = $users->fetch()) ...

Once you've completed that loop, you need to reset the cursor on the database side before you can loop over it again.

$users = $dbh->query($sql);
foreach ($users as $row) {
    print $row["name"] . "-" . $row["sex"] ."<br/>";
}
echo "<br/>";
$result = $users->fetch(PDO::FETCH_ASSOC);
foreach($result as $key => $value) {
    echo $key . "-" . $value . "<br/>";
}

Here all results are being output by the first loop. The call to fetch will return false, since you have already exhausted the result set (see above), so you get an error trying to loop over false.

In the last example you are simply fetching the first result row and are looping over it.

I did only one thing and it worked for me .. check your code is this method there ..

setResizable(false);

if it false make it true and it will work just fine .. I hope it helped ..

I think you should try

data = {"shareInfo":[{"id":"1","a":"sss","b":"sss","question":"whi?"},
{"id":"2","a":"sss","b":"sss","question":"whi?"},
{"id":"3","a":"sss","b":"sss","question":"whi?"},
{"id":"4","a":"sss","b":"sss","question":"whi?"}]};

ShareInfoLength = data.shareInfo.length;
alert(ShareInfoLength);
for(var i=0; i<ShareInfoLength; i++)
{
alert(Object.keys(data.shareInfo[i]).length);
}

Another library-based option: use d3-time-format:

const formatter = d3.timeFormat('%U');
const weekNum = formatter(new Date());

If you need your script to be portable and you would rather not have any 3rd party dependencies, this is how you send POST request purely in Python 3.

from urllib.parse import urlencode
from urllib.request import Request, urlopen

url = 'https://httpbin.org/post' # Set destination URL here
post_fields = {'foo': 'bar'}     # Set POST fields here

request = Request(url, urlencode(post_fields).encode())
json = urlopen(request).read().decode()
print(json)

Sample output:

{
  "args": {}, 
  "data": "", 
  "files": {}, 
  "form": {
    "foo": "bar"
  }, 
  "headers": {
    "Accept-Encoding": "identity", 
    "Content-Length": "7", 
    "Content-Type": "application/x-www-form-urlencoded", 
    "Host": "httpbin.org", 
    "User-Agent": "Python-urllib/3.3"
  }, 
  "json": null, 
  "origin": "127.0.0.1", 
  "url": "https://httpbin.org/post"
}

Multi line comments

If there are large number of lines you want to comment out then it will be better if you can make multi line comments rather than commenting out every line.

See this post by Rob van der Woude on comment blocks:

The batch language doesn't have comment blocks, though there are ways to accomplish the effect.

This line is comment.
And so is this line.
And this one...
:EndComment1

You can use GOTO Label and :Label for making block comments.

Or, If the comment block appears at the end of the batch file, you can write EXIT at end of code and then any number of comments for your understanding.

@ECHO OFF
REM Do something
  •
  •
REM End of code; use GOTO:EOF instead of EXIT for Windows NT and later
EXIT

Start of comment block at end of batch file
This line is comment.
And so is this line.
And this one...

This may do what you want:

find /dev \( ! -name /dev -prune \) -type f -print

A way that I have done this is as follows:

At the python shell:

>>> from cryptography.fernet import Fernet
>>> key = Fernet.generate_key()
>>> print(key)
b'B8XBLJDiroM3N2nCBuUlzPL06AmfV4XkPJ5OKsPZbC4='
>>> cipher = Fernet(key)
>>> password = "thepassword".encode('utf-8')
>>> token = cipher.encrypt(password)
>>> print(token)
b'gAAAAABe_TUP82q1zMR9SZw1LpawRLHjgNLdUOmW31RApwASzeo4qWSZ52ZBYpSrb1kUeXNFoX0tyhe7kWuudNs2Iy7vUwaY7Q=='

Then, create a module with the following code:

from cryptography.fernet import Fernet

# you store the key and the token
key = b'B8XBLJDiroM3N2nCBuUlzPL06AmfV4XkPJ5OKsPZbC4='
token = b'gAAAAABe_TUP82q1zMR9SZw1LpawRLHjgNLdUOmW31RApwASzeo4qWSZ52ZBYpSrb1kUeXNFoX0tyhe7kWuudNs2Iy7vUwaY7Q=='

# create a cipher and decrypt when you need your password
cipher = Fernet(key)

mypassword = cipher.decrypt(token).decode('utf-8')

Once you've done this, you can either import mypassword directly or you can import the token and cipher to decrypt as needed.

Obviously, there are some shortcomings to this approach. If someone has both the token and the key (as they would if they have the script), they can decrypt easily. However it does obfuscate, and if you compile the code (with something like Nuitka) at least your password won't appear as plain text in a hex editor.

A very simple solution is to add the database name with your table name like if your DB name is DBMS and table is info then it will be DBMS.info for any query.

If your query is

select * from STUDENTREC where ROLL_NO=1;

it might show an error but

select * from DBMS.STUDENTREC where ROLL_NO=1; 

it doesn't because now actually your table is found.

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

• Wikipedia: Algorithms for calculating variance

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

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

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

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

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

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

Just use it as you would a non-concurrent collection. The Concurrent[Collection] classes wrap the regular collections so that you don't have to think about synchronizing access.

Edit: ConcurrentLinkedList isn't actually just a wrapper, but rather a better concurrent implementation. Either way, you don't have to worry about synchronization.

Your problem is most likely with the video file, not the code. Your video is most likely not "safe for streaming". See where to place videos to stream android for more.

You must use .clearAnimation(); method in UI thread:

runOnUiThread(new Runnable() {
    @Override
    public void run() {
        v.clearAnimation();
    }
});

Suppose your element is entire [object HTMLDocument]. You can convert it to a String this way:

const htmlTemplate = `<!DOCTYPE html><html lang="en"><head></head><body></body></html>`;

const domparser = new DOMParser();
const doc = domparser.parseFromString(htmlTemplate, "text/html"); // [object HTMLDocument]

const doctype = '<!DOCTYPE html>';
const html = doc.documentElement.outerHTML;

console.log(doctype + html);

find "$PWD" -type f -name "*.in"

if you use the eclipse, see the bellow image to allow the compiler to store the information about method parameters

./main.go (in package main)
./a/a.go (in package a)
./a/b.go (in package a)

in this case:
main.go import "./a"

It can call the function in the a.go and b.go,that with first letter caps on.

I noticed one error in Dave Ward's answer (perhaps a recent change?): The query string paramaters are in request.query, not request.params. (See https://stackoverflow.com/a/6913287/166530 )

request.params by default is filled with the value of any "component matches" in routes, i.e.

app.get('/user/:id', function(request, response){
  response.send('user ' + request.params.id);
});

and, if you have configured express to use its bodyparser (app.use(express.bodyParser());) also with POST'ed formdata. (See How to retrieve POST query parameters? )

Use the replace function in js:

var emailAdd = $(this).text().replace(/ /g,'');

That will remove all the spaces

If you want to remove the leading and trailing whitespace only, use the jQuery $.trim method :

var emailAdd = $.trim($(this).text());

for only date in specific format

    let dateFormatter1 = NSDateFormatter()
    dateFormatter1.dateStyle = .MediumStyle
    dateFormatter1.timeStyle = .NoStyle
    dateFormatter1.dateFormat = "dd-MM-yyyy"
    let date = dateFormatter1.stringFromDate(NSDate())

The only selector I see is a[id$="name"] (all links with id finishing by "name") but it's not as restrictive as it should.

from python 3 doc

%d is for decimal integer

%s is for generic string or object and in case of object, it will be converted to string

Consider the following code

name ='giacomo'
number = 4.3
print('%s %s %d %f %g' % (name, number, number, number, number))

the out put will be

giacomo 4.3 4 4.300000 4.3

as you can see %d will truncate to integer, %s will maintain formatting, %f will print as float and %g is used for generic number

obviously

print('%d' % (name))

will generate an exception; you cannot convert string to number

Objective C:

[[NSString alloc] initWithData:nsdata encoding:NSASCIIStringEncoding];

Swift:

let str = String(data: data, encoding: .ascii)

Try this, its work for me:

Date date = javax.xml.bind.DatatypeConverter.parseDateTime("2013-06-01T12:45:01+04:00").getTime();

In Java 8:

OffsetDateTime dt = OffsetDateTime.parse("2010-03-01T00:00:00-08:00");

It is very simple to update using Inner join query in SQL .You can do it without using FROM clause. Here is an example :

    UPDATE customer_table c 

      INNER JOIN  
          employee_table e
          ON (c.city_id = e.city_id)  

    SET c.active = "Yes"

    WHERE c.city = "New york";

I like PDFTIFF.com to convert PDF to TIFF, it can handle unlimited pages

One simple solution that comes to mind would be:

for i in MyList:
    # Check if 'i' is the last element in the list
    if i == MyList[-1]:
        # Do something different for the last
    else:
        # Do something for all other elements

A second equally simple solution could be achieved by using a counter:

# Count the no. of elements in the list
ListLength = len(MyList)
# Initialize a counter
count = 0

for i in MyList:
    # increment counter
    count += 1
    # Check if 'i' is the last element in the list
    # by using the counter
    if count == ListLength:
        # Do something different for the last
    else:
        # Do something for all other elements

I implemented a horizontal/vertical search, (first make a div full of vertical line links arranged horizontally, then make a div full of horizontal line links arranged vertically, and simply see which one has the hover state) like Tim Down's idea above, and it works pretty fast. Sadly, does not work on Chrome 32 on KDE.

As odd as it sound when you want to permit nested attributes you do specify the attributes of nested object within an array. In your case it would be

Update as suggested by @RafaelOliveira

params.require(:measurement)
      .permit(:name, :groundtruth => [:type, :coordinates => []])

On the other hand if you want nested of multiple objects then you wrap it inside a hash… like this

params.require(:foo).permit(:bar, {:baz => [:x, :y]})

Rails actually have pretty good documentation on this: http://api.rubyonrails.org/classes/ActionController/Parameters.html#method-i-permit

For further clarification, you could look at the implementation of permit and strong_parameters itself: https://github.com/rails/rails/blob/master/actionpack/lib/action_controller/metal/strong_parameters.rb#L246-L247

ISLE (InstallShield Limited Edition) is the "replacement" of the Visual Studio Setup and Deploy project, but many users think Microsoft took wrong step with removing .vdproj support from Visual Studio 2012 (and later ones) and supporting third-party company software.

Many people asked for returning it back (Bring back the basic setup and deployment project type Visual Studio Installer), but Microsoft is deaf to our voices... really sad.

As WiX is really complicated, I think it is worth to try some free installation systems - NSIS or Inno Setup. Both are scriptable and easy to learn - but powerful as original SADP.

I have created a really nice Visual Studio extension for NSIS and Inno Setup with many features (intellisense, syntax highlighting, navigation bars, compilation directly from Visual Studio, etc.). You can try it at www.visual-installer.com (sorry for self promo :)

Download Inno Setup (jrsoftware.org/isdl.php) or NSIS (nsis.sourceforge.net/Download) and install V&I (unsigned-softworks.sk/visual-installer/downloads.html).

All installers are simple Next/Next/Next...

In Visual Studio, select menu File -> New -> Project, choose NSISProject or Inno Setup, and a new project will be created (with full sources).

For debugging purposes, you can use the DLL file. You can run it using dotnet ConsoleApp2.dll. If you want to generate an EXE file, you have to generate a self-contained application.

To generate a self-contained application (EXE in Windows), you must specify the target runtime (which is specific to the operating system you target).

Pre-.NET Core 2.0 only: First, add the runtime identifier of the target runtimes in the .csproj file (list of supported RIDs):

<PropertyGroup>
    <RuntimeIdentifiers>win10-x64;ubuntu.16.10-x64</RuntimeIdentifiers>
</PropertyGroup>

The above step is no longer required starting with .NET Core 2.0.

Then, set the desired runtime when you publish your application:

dotnet publish -c Release -r win10-x64
dotnet publish -c Release -r ubuntu.16.10-x64

Observable

/*
  function geo_success(position) {
    do_something(position.coords.latitude, position.coords.longitude);
  }

  function geo_error() {
    alert("Sorry, no position available.");
  }

  var geo_options = {
    enableHighAccuracy: true,
    maximumAge        : 30000,
    timeout           : 27000
  };

  var wpid = navigator.geolocation.watchPosition(geo_success, geo_error, geo_options);
  */
  getLocation(): Observable<Position> {
    return Observable.create((observer) => {
      const watchID = navigator.geolocation.watchPosition((position: Position) => {
        observer.next(position);
      });
      return () => {
        navigator.geolocation.clearWatch(watchID);
      };
    });
  }

There is one very funny thing (and has a technical relevance) which might waste your hours so thought of sharing it here -

I created a console application project ConsoleApplication1 and a class library project ClassLibrary1.

All the code which was making the p/invoke was present in ClassLibrary1.dll. So before debugging the application from visual studio I simply copied the C++ unmanaged assembly (myUnmanagedFunctions.dll) into the \bin\debug\ directory of ClassLibrary1 project so that it can be loaded at run-time by the CLR.

I kept getting the

Unable to load DLL

error for hours. Later on I realized that all such unmanaged assemblies which are to be loaded need to be copied into the \bin\debug directory of the start-up project ConsoleApplication1 which is usually a win form, console or web application.

So please be cautious the Current Directory in the accepted answer actually means Current Directory of main executable from where you application process is starting. Looks like an obvious thing but might not be so at times.

Lesson Learnt - Always place the unamanaged dlls in the same directory as the start-up executable to ensure that it can be found.

There are different ways for this:

1.Building C# Applications Using csc.exe

While it is true that you might never decide to build a large-scale application using nothing but the C# command-line compiler, it is important to understand the basics of how to compile your code files by hand.

2.Building .NET Applications Using Notepad++

Another simple text editor I’d like to quickly point out is the freely downloadable Notepad++ application. This tool can be obtained from http://notepad-plus.sourceforge.net. Unlike the primitive Windows Notepad application, Notepad++ allows you to author code in a variety of languages and supports

3.Building .NET Applications Using SharpDevelop

As you might agree, authoring C# code with Notepad++ is a step in the right direction, compared to Notepad. However, these tools do not provide rich IntelliSense capabilities for C# code, designers for building graphical user interfaces, project templates, or database manipulation utilities. To address such needs, allow me to introduce the next .NET development option: SharpDevelop (also known as "#Develop").You can download it from http://www.sharpdevelop.com.

The first thing I would recommend is to take measurements. Where are you losing your time? Is it in the read, or the write?

Over 100,000 accesses (sum the times): How much time is spent allocating the buffer array? How much time is spent opening the file for read (is it the same file every time?) How much time is spent in read and write operations?

If you aren't doing any type of transformation on the file, do you need a BinaryWriter, or can you use a filestream for writes? (try it, do you get identical output? does it save time?)

It is the same as in eclipse:

• Select text for upper case and Ctrl + Shift + X
• Select text for lower case and Ctrl + Shift + Y

I had the same problem in Flask.

When I added:

__init__.py

to tests folder, problem disappeared :)

Probably application couldn't recognize folder tests as module

According to Apache Tomcat 7 JNDI Datasource HOW-TO page there must be a resource configuration in web.xml:

<resource-ref>
  <description>DB Connection</description>
  <res-ref-name>jdbc/TestDB</res-ref-name>
  <res-type>javax.sql.DataSource</res-type>
  <res-auth>Container</res-auth>

That works for me

Try the following :)

        textBox1.Multiline = true;
        textBox1.Height = 100;
        textBox1.Width = 173;

If the strings you are concatenating are literals, use String literal concatenation

re.compile(
        "[A-Za-z_]"       # letter or underscore
        "[A-Za-z0-9_]*"   # letter, digit or underscore
    )

This is useful if you want to comment on part of a string (as above) or if you want to use raw strings or triple quotes for part of a literal but not all.

Since this happens at the syntax layer it uses zero concatenation operators.

This is my take on the various answers. I wanted to actually see the logged messages, even if I did not have the IE console open when they were fired, so I push them into a console.messages array that I create. I also added a function console.dump() to facilitate viewing the whole log. console.clear() will empty the message queue.

This solutions also "handles" the other Console methods (which I believe all originate from the Firebug Console API)

Finally, this solution is in the form of an IIFE, so it does not pollute the global scope. The fallback function argument is defined at the bottom of the code.

I just drop it in my master JS file which is included on every page, and forget about it.

(function (fallback) {    

    fallback = fallback || function () { };

    // function to trap most of the console functions from the FireBug Console API. 
    var trap = function () {
        // create an Array from the arguments Object           
        var args = Array.prototype.slice.call(arguments);
        // console.raw captures the raw args, without converting toString
        console.raw.push(args);
        var message = args.join(' ');
        console.messages.push(message);
        fallback(message);
    };

    // redefine console
    if (typeof console === 'undefined') {
        console = {
            messages: [],
            raw: [],
            dump: function() { return console.messages.join('\n'); },
            log: trap,
            debug: trap,
            info: trap,
            warn: trap,
            error: trap,
            assert: trap,
            clear: function() { 
                  console.messages.length = 0; 
                  console.raw.length = 0 ;
            },
            dir: trap,
            dirxml: trap,
            trace: trap,
            group: trap,
            groupCollapsed: trap,
            groupEnd: trap,
            time: trap,
            timeEnd: trap,
            timeStamp: trap,
            profile: trap,
            profileEnd: trap,
            count: trap,
            exception: trap,
            table: trap
        };
    }

})(null); // to define a fallback function, replace null with the name of the function (ex: alert)

Some extra info

The line var args = Array.prototype.slice.call(arguments); creates an Array from the arguments Object. This is required because arguments is not really an Array.

trap() is a default handler for any of the API functions. I pass the arguments to message so that you get a log of the arguments that were passed to any API call (not just console.log).

Edit

I added an extra array console.raw that captures the arguments exactly as passed to trap(). I realized that args.join(' ') was converting objects to the string "[object Object]" which may sometimes be undesirable. Thanks bfontaine for the suggestion.

I found it pretty easy like this

    using System;
    using System.Data;
    using System.IO;
    using Excel;

    public DataTable ExcelToDataTableUsingExcelDataReader(string storePath)
    {
        FileStream stream = File.Open(storePath, FileMode.Open, FileAccess.Read);

        string fileExtension = Path.GetExtension(storePath);
        IExcelDataReader excelReader = null;
        if (fileExtension == ".xls")
        {
            excelReader = ExcelReaderFactory.CreateBinaryReader(stream);
        }
        else if (fileExtension == ".xlsx")
        {
            excelReader = ExcelReaderFactory.CreateOpenXmlReader(stream);
        }

        excelReader.IsFirstRowAsColumnNames = true;
        DataSet result = excelReader.AsDataSet();
        var test = result.Tables[0];
        return result.Tables[0];
    }

Note: you need to install SharpZipLib package for this

Install-Package SharpZipLib

neat and clean! ;)

Arrays on the type level

An array type is denoted as T[n] where T is the element type and n is a positive size, the number of elements in the array. The array type is a product type of the element type and the size. If one or both of those ingredients differ, you get a distinct type:

#include <type_traits>

static_assert(!std::is_same<int[8], float[8]>::value, "distinct element type");
static_assert(!std::is_same<int[8],   int[9]>::value, "distinct size");

Note that the size is part of the type, that is, array types of different size are incompatible types that have absolutely nothing to do with each other. sizeof(T[n]) is equivalent to n * sizeof(T).

Array-to-pointer decay

The only "connection" between T[n] and T[m] is that both types can implicitly be converted to T*, and the result of this conversion is a pointer to the first element of the array. That is, anywhere a T* is required, you can provide a T[n], and the compiler will silently provide that pointer:

                  +---+---+---+---+---+---+---+---+
the_actual_array: |   |   |   |   |   |   |   |   |   int[8]
                  +---+---+---+---+---+---+---+---+
                    ^
                    |
                    |
                    |
                    |  pointer_to_the_first_element   int*

This conversion is known as "array-to-pointer decay", and it is a major source of confusion. The size of the array is lost in this process, since it is no longer part of the type (T*). Pro: Forgetting the size of an array on the type level allows a pointer to point to the first element of an array of any size. Con: Given a pointer to the first (or any other) element of an array, there is no way to detect how large that array is or where exactly the pointer points to relative to the bounds of the array. Pointers are extremely stupid.

Arrays are not pointers

The compiler will silently generate a pointer to the first element of an array whenever it is deemed useful, that is, whenever an operation would fail on an array but succeed on a pointer. This conversion from array to pointer is trivial, since the resulting pointer value is simply the address of the array. Note that the pointer is not stored as part of the array itself (or anywhere else in memory). An array is not a pointer.

static_assert(!std::is_same<int[8], int*>::value, "an array is not a pointer");

One important context in which an array does not decay into a pointer to its first element is when the & operator is applied to it. In that case, the & operator yields a pointer to the entire array, not just a pointer to its first element. Although in that case the values (the addresses) are the same, a pointer to the first element of an array and a pointer to the entire array are completely distinct types:

static_assert(!std::is_same<int*, int(*)[8]>::value, "distinct element type");

The following ASCII art explains this distinction:

      +-----------------------------------+
      | +---+---+---+---+---+---+---+---+ |
+---> | |   |   |   |   |   |   |   |   | | int[8]
|     | +---+---+---+---+---+---+---+---+ |
|     +---^-------------------------------+
|         |
|         |
|         |
|         |  pointer_to_the_first_element   int*
|
|  pointer_to_the_entire_array              int(*)[8]

Note how the pointer to the first element only points to a single integer (depicted as a small box), whereas the pointer to the entire array points to an array of 8 integers (depicted as a large box).

The same situation arises in classes and is maybe more obvious. A pointer to an object and a pointer to its first data member have the same value (the same address), yet they are completely distinct types.

If you are unfamiliar with the C declarator syntax, the parenthesis in the type int(*)[8] are essential:

• int(*)[8] is a pointer to an array of 8 integers.
• int*[8] is an array of 8 pointers, each element of type int*.

Accessing elements

C++ provides two syntactic variations to access individual elements of an array. Neither of them is superior to the other, and you should familiarize yourself with both.

Pointer arithmetic

Given a pointer p to the first element of an array, the expression p+i yields a pointer to the i-th element of the array. By dereferencing that pointer afterwards, one can access individual elements:

std::cout << *(x+3) << ", " << *(x+7) << std::endl;

If x denotes an array, then array-to-pointer decay will kick in, because adding an array and an integer is meaningless (there is no plus operation on arrays), but adding a pointer and an integer makes sense:

   +---+---+---+---+---+---+---+---+
x: |   |   |   |   |   |   |   |   |   int[8]
   +---+---+---+---+---+---+---+---+
     ^           ^               ^
     |           |               |
     |           |               |
     |           |               |
x+0  |      x+3  |          x+7  |     int*

(Note that the implicitly generated pointer has no name, so I wrote x+0 in order to identify it.)

If, on the other hand, x denotes a pointer to the first (or any other) element of an array, then array-to-pointer decay is not necessary, because the pointer on which i is going to be added already exists:

   +---+---+---+---+---+---+---+---+
   |   |   |   |   |   |   |   |   |   int[8]
   +---+---+---+---+---+---+---+---+
     ^           ^               ^
     |           |               |
     |           |               |
   +-|-+         |               |
x: | | |    x+3  |          x+7  |     int*
   +---+

Note that in the depicted case, x is a pointer variable (discernible by the small box next to x), but it could just as well be the result of a function returning a pointer (or any other expression of type T*).

Indexing operator

Since the syntax *(x+i) is a bit clumsy, C++ provides the alternative syntax x[i]:

std::cout << x[3] << ", " << x[7] << std::endl;

Due to the fact that addition is commutative, the following code does exactly the same:

std::cout << 3[x] << ", " << 7[x] << std::endl;

The definition of the indexing operator leads to the following interesting equivalence:

&x[i]  ==  &*(x+i)  ==  x+i

However, &x[0] is generally not equivalent to x. The former is a pointer, the latter an array. Only when the context triggers array-to-pointer decay can x and &x[0] be used interchangeably. For example:

T* p = &array[0];  // rewritten as &*(array+0), decay happens due to the addition
T* q = array;      // decay happens due to the assignment

On the first line, the compiler detects an assignment from a pointer to a pointer, which trivially succeeds. On the second line, it detects an assignment from an array to a pointer. Since this is meaningless (but pointer to pointer assignment makes sense), array-to-pointer decay kicks in as usual.

Ranges

An array of type T[n] has n elements, indexed from 0 to n-1; there is no element n. And yet, to support half-open ranges (where the beginning is inclusive and the end is exclusive), C++ allows the computation of a pointer to the (non-existent) n-th element, but it is illegal to dereference that pointer:

   +---+---+---+---+---+---+---+---+....
x: |   |   |   |   |   |   |   |   |   .   int[8]
   +---+---+---+---+---+---+---+---+....
     ^                               ^
     |                               |
     |                               |
     |                               |
x+0  |                          x+8  |     int*

For example, if you want to sort an array, both of the following would work equally well:

std::sort(x + 0, x + n);
std::sort(&x[0], &x[0] + n);

Note that it is illegal to provide &x[n] as the second argument since this is equivalent to &*(x+n), and the sub-expression *(x+n) technically invokes undefined behavior in C++ (but not in C99).

Also note that you could simply provide x as the first argument. That is a little too terse for my taste, and it also makes template argument deduction a bit harder for the compiler, because in that case the first argument is an array but the second argument is a pointer. (Again, array-to-pointer decay kicks in.)

Well, this question appears on top of search results, so I believe we need code example here. Here's the Python code:

import cv2

def apply_mask(frame, mask):
    """Apply binary mask to frame, return in-place masked image."""
    return cv2.bitwise_and(frame, frame, mask=mask)

Mask and frame must be the same size, so pixels remain as-is where mask is 1 and are set to zero where mask pixel is 0.

And for C++ it's a little bit different:

cv::Mat inFrame; // Original (non-empty) image
cv::Mat mask; // Original (non-empty) mask

// ...

cv::Mat outFrame;  // Result output
inFrame.copyTo(outFrame, mask);

I think the explanation of why exception is thrown is very clear with the answers provided here. I just wish to complement with the way I usually work with these collections. Because, some times, I use the collection more then once and have to test if null every time. To avoid that, I do the following:

    var returnArray = DoSomething() ?? Enumerable.Empty<int>();

    foreach (int i in returnArray)
    {
        // do some more stuff
    }

This way we can use the collection as much as we want without fear the exception and we don't polute the code with excessive conditional statements.

Using the null check operator ?. is also a great approach. But, in case of arrays (like the example in the question), it should be transformed into List before:

    int[] returnArray = DoSomething();

    returnArray?.ToList().ForEach((i) =>
    {
        // do some more stuff
    });

You might wanna use include method in JS.

var sentence = "This is my line";
console.log(sentence.includes("my"));
//returns true if substring is present.

PS: includes is case sensitive.

if (HttpContext.Current.Session["emp_num"] != null)
{
     // code if session is not null
}

• if at all above fails.

Node.js uses the environmental variable NODE_PATH to allow for specifying additional directories to include in the module search path. You can use npm itself to tell you where global modules are stored with the npm root -g command. So putting those two together, you can make sure global modules are included in your search path with the following command (on Linux-ish)

export NODE_PATH=$(npm root --quiet -g)

If you would like to 'add' additional items to a page, you may want to create an array of maps. This is how I created an array of maps and then added results to it:

import { Product } from '../models/product';

products: Array<Product>;          // Initialize the array.

[...]

let i = 0;
this.service.products( i , (result) => {

    if ( i == 0 ) {
        // Create the first element of the array.
        this.products = Array(result);
    } else { 
        // Add to the array of maps.
        this.products.push(result);
    }

});

Where product.ts look like...

export class Product {
    id: number;
    [...]
}

It is very easy to do, all you need to do is 1) download 5.6 from [1]: https://sourceforge.net/projects/xampp/files/XAMPP%20Windows/5.6.36/, the run the setup and install in folder "xampp"

2) download 7.6 from [https://sourceforge.net/projects/xampp/files/XAMPP%20Windows/7.4.2/xampp-portable-windows-x64-7.4.2-0-VC15-installer.exe/download][1] and run the setup in "xampp2"

NOte: after that you now have separate xampp installed in your system. all you do now is to run each xampp as a separate entity. Alway quite the 5.6 if you want to run 7.6

The most simple way is to use pack() method before visualizing the JFrame object. here is an example:

myFrame frm = new myFrame();
frm.pack();
frm.setVisible(true);

str="abcdef"

str.index('c') #=> 2 #String matching approach
str=~/c/ #=> 2 #Regexp approach 
$~ #=> #<MatchData "c">

Hope it helps. :)

Here's the Javadoc in Oracle's website for the Date class: https://docs.oracle.com/javase/8/docs/api/java/util/Date.html
If you scroll down to "Constructor Summary," you'll see the different options for how a Date object can be instantiated. Like all objects in Java, you create a new one with the following:

Date firstDate = new Date(ConstructorArgsHere);

Now you have a bit of a choice. If you don't pass in any arguments, and just do this,

Date firstDate = new Date();

it will represent the exact date and time at which you called it. Here are some other constructors you may want to make use of:

Date firstDate1 = new Date(int year, int month, int date);
Date firstDate2 = new Date(int year, int month, int date, int hrs, int min);
Date firstDate3 = new Date(int year, int month, int date, int hrs, int min, int sec);

1. check wamp server icon is green or not if it is green then it is working if not then you have to follow these steps to do

   a. all the programs should be closed before running the wamp because most of the cases some softwares like skype takes the same port (80) which is using by wamp.

   b. you can change the port of skype : Tool-s->oprions->advanced->connection untick use port 80

2. restart the wamp it will work.

SECOND case

1. when you click on the project in loalhost it does not show the localhost infront of the project name and because of that it looks like wamp is not working then you have to one thing on only

   . go to wamp index.php file and change $suppress_localhost = false; from $suppress_localhost = true; or try vice versa it will work

dbms_output.put_line('Hi,');
dbms_output.put_line('good');
dbms_output.put_line('morning');
dbms_output.put_line('friends');

or

DBMS_OUTPUT.PUT_LINE('Hi, ' || CHR(13) || CHR(10) || 
                     'good' || CHR(13) || CHR(10) ||
                     'morning' || CHR(13) || CHR(10) ||
                     'friends' || CHR(13) || CHR(10) ||);

try it.

var_dump() will show you the type of the thing as well as what's in it.

So you'll get => (string)"var" Example is here.

print_r() will just output the content.

Would output => "var" Example is here.

It's an old question but it worth to mention that in Angular 1.4 $httpParamSerializer is added and when using $http.post, if we use $httpParamSerializer(params) to pass the parameters, everything works like a regular post request and no JSON deserializing is needed on server side.

https://docs.angularjs.org/api/ng/service/$httpParamSerializer

This is a good example where you want to get count of Pincode which stored in the last of address field

SELECT DISTINCT
    RIGHT (address, 6),
    count(*) AS count
FROM
    datafile
WHERE
    address IS NOT NULL
GROUP BY
    RIGHT (address, 6)

I think it is a better idea to start working with a raw data and then translate it to DOM (document object model)

I would suggest you to work with array of objects and then output it to the DOM in order to accomplish your task.

You can see working example of following code at http://www.softxml.com/stackoverflow/shoppingCart.htm

You can try following approach:

//create array that will hold all ordered products
    var shoppingCart = [];

    //this function manipulates DOM and displays content of our shopping cart
    function displayShoppingCart(){
        var orderedProductsTblBody=document.getElementById("orderedProductsTblBody");
        //ensure we delete all previously added rows from ordered products table
        while(orderedProductsTblBody.rows.length>0) {
            orderedProductsTblBody.deleteRow(0);
        }

        //variable to hold total price of shopping cart
        var cart_total_price=0;
        //iterate over array of objects
        for(var product in shoppingCart){
            //add new row      
            var row=orderedProductsTblBody.insertRow();
            //create three cells for product properties 
            var cellName = row.insertCell(0);
            var cellDescription = row.insertCell(1);
            var cellPrice = row.insertCell(2);
            cellPrice.align="right";
            //fill cells with values from current product object of our array
            cellName.innerHTML = shoppingCart[product].Name;
            cellDescription.innerHTML = shoppingCart[product].Description;
            cellPrice.innerHTML = shoppingCart[product].Price;
            cart_total_price+=shoppingCart[product].Price;
        }
        //fill total cost of our shopping cart 
        document.getElementById("cart_total").innerHTML=cart_total_price;
    }


    function AddtoCart(name,description,price){
       //Below we create JavaScript Object that will hold three properties you have mentioned:    Name,Description and Price
       var singleProduct = {};
       //Fill the product object with data
       singleProduct.Name=name;
       singleProduct.Description=description;
       singleProduct.Price=price;
       //Add newly created product to our shopping cart 
       shoppingCart.push(singleProduct);
       //call display function to show on screen
       displayShoppingCart();

    }  


    //Add some products to our shopping cart via code or you can create a button with onclick event
    //AddtoCart("Table","Big red table",50);
    //AddtoCart("Door","Big yellow door",150);
    //AddtoCart("Car","Ferrari S23",150000);

Hope you will find it useful.

For safety (buffer overflow) I recommend to use snprintf()

const int MAX_BUF = 1000;
char* Buffer = malloc(MAX_BUF);

int length = 0;
length += snprintf(Buffer+length, MAX_BUF-length, "Hello World");
length += snprintf(Buffer+length, MAX_BUF-length, "Good Morning");
length += snprintf(Buffer+length, MAX_BUF-length, "Good Afternoon");

foreach (var item in listOfItems) {
  if (condition_is_met)
    // Any processing you may need to complete here...
    break; // return true; also works if you're looking to
           // completely exit this function.
}

Should do the trick. The break statement will just end the execution of the loop, while the return statement will obviously terminate the entire function. Judging from your question you may want to use the return true; statement.

You can load the text file into a textfile Hive table and then insert the data from this table into your sequencefile.

Start with a tab delimited file:

% cat /tmp/input.txt
a       b
a2      b2

create a sequence file

hive> create table test_sq(k string, v string) stored as sequencefile;

try to load; as expected, this will fail:

hive> load data local inpath '/tmp/input.txt' into table test_sq;

But with this table:

hive> create table test_t(k string, v string) row format delimited fields terminated by '\t' stored as textfile;

The load works just fine:

hive> load data local inpath '/tmp/input.txt' into table test_t;
OK
hive> select * from test_t;
OK
a       b
a2      b2

Now load into the sequence table from the text table:

insert into table test_sq select * from test_t;

Can also do load/insert with overwrite to replace all.

Another Way That worked for me is to Subclass UINavigationBar And leave the drawRect Method empty !!

@IBDesignable class MONavigationBar: UINavigationBar {


// Only override drawRect: if you perform custom drawing.
// An empty implementation adversely affects performance during animation.
override func drawRect(rect: CGRect) {
    // Drawing code
}}

must means: The clause (query) must appear in matching documents. These clauses must match, like logical AND.

should means: At least one of these clauses must match, like logical OR.

Basically they are used like logical operators AND and OR. See this.

Now in a bool query:

must means: Clauses that must match for the document to be included.

should means: If these clauses match, they increase the _score; otherwise, they have no effect. They are simply used to refine the relevance score for each document.

Yes you can use multiple filters inside must.

Just notice that if you work with Fragments using ViewPager, it's pretty easy. You only need to call this method: setOffscreenPageLimit().

Accordign to the docs:

Set the number of pages that should be retained to either side of the current page in the view hierarchy in an idle state. Pages beyond this limit will be recreated from the adapter when needed.

Similar issue here

use this:

$('form.contactForm input[type="text"],texatrea, select').val('');

or if you have a reference to the form with this:

$('input[type="text"],texatrea, select', this).val('');

:input === <input> + <select>s + <textarea>s

What about using the following:

int number = input.nextInt();
if (number < 0) {
    // negative
} else {
   // it's a positive
}

I had same error, I think the problem is that the error text is confusing, because its giving a false key name.

In your case It should say "There is no ViewData item of type 'IEnumerable' that has the key "Submarkets"".

My error was a misspelling in the view code (your "Submarkets"), but the error text made me go crazy.

I post this answer because I want to say people looking for this error, like I was, that the problem is that its not finding the IENumerable, but in the var that its supposed to look for it ("Submarkets" in this case), not in the one showed in error ("submarket_0").

Accepted answer is very interesting, but as you said the convention is applied if you dont specify the 2nd parameter, in this case it was specified, but the var was not found (in your case because the viewdata had not it, in my case because I misspelled the var name)

Hope this helps!

Courtesy of Microsoft Excel: 

Maybe you want set -e:

www.davidpashley.com/articles/writing-robust-shell-scripts.html#id2382181:

This tells bash that it should exit the script if any statement returns a non-true return value. The benefit of using -e is that it prevents errors snowballing into serious issues when they could have been caught earlier. Again, for readability you may want to use set -o errexit.

You need to get a reference of your form, and after that you can iterate the elements collection. So, assuming for instance:

<form method="POST" action="submit.php" id="my-form">
  ..etc..
</form>

You will have something like:

var elements = document.getElementById("my-form").elements;

for (var i = 0, element; element = elements[i++];) {
    if (element.type === "text" && element.value === "")
        console.log("it's an empty textfield")
}

Notice that in browser that would support querySelectorAll you can also do something like:

var elements = document.querySelectorAll("#my-form input[type=text][value='']")

And you will have in elements just the element that have an empty value attribute. Notice however that if the value is changed by the user, the attribute will be remain the same, so this code is only to filter by attribute not by the object's property. Of course, you can also mix the two solution:

var elements = document.querySelectorAll("#my-form input[type=text]")

for (var i = 0, element; element = elements[i++];) {
    if (element.value === "")
        console.log("it's an empty textfield")
}

You will basically save one check.

You need to use ContextCompat.getColor(), which is part of the Support V4 Library (so it will work for all the previous API).

ContextCompat.getColor(context, R.color.my_color)

As specified in the documentation, "Starting in M, the returned color will be styled for the specified Context's theme". SO no need to worry about it.

You can add the Support V4 library by adding the following to the dependencies array inside your app build.gradle:

compile 'com.android.support:support-v4:23.0.1'

--save-dev means "needed only when developing"

• e.g. the final users using your package will not want/need/care about what testing suite you used; they will only want packages that are absolutely required to run your code in a production environment. This flag marks what is needed when developing vs production.

The easiest way is to make the "button image" as a separate image. Then place it over the main image (using "style="position: absolute;". Assign the URL link to "button image". and smile :)

      System.out.println(jarName);
  

It uses the javaxt-core jar which can be downloaded from http://www.javaxt.com/downloads/

As per the HTML:

<html>
    <body>
    <p class="content">Link1.</p>
    </body>
<html>
<html>
    <body>
    <p class="content">Link2.</p>
    </body>
<html>

Two(2) <p> elements are having the same class content.

So to filter the elements having the same class i.e. content and create a list you can use either of the following Locator Strategies:

• Using class_name:

  elements = driver.find_elements_by_class_name("content")
  

• Using css_selector:

   elements = driver.find_elements_by_css_selector(".content")
  

• Using xpath:

  elements = driver.find_elements_by_xpath("//*[@class='content']")
  

Ideally, to click on the element you need to induce WebDriverWait for the visibility_of_all_elements_located() and you can use either of the following Locator Strategies:

• Using CLASS_NAME:

  elements = WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.CLASS_NAME, "content")))
  

• Using CSS_SELECTOR:

  elements = WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.CSS_SELECTOR, ".content")))
  

• Using XPATH:

  elements = WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.XPATH, "//*[@class='content']")))
  

• Note : You have to add the following imports :

  from selenium.webdriver.support.ui import WebDriverWait
  from selenium.webdriver.common.by import By
  from selenium.webdriver.support import expected_conditions as EC

I'm not familiar with napping, but using Golang's net/http package works fine (playground):

func main() {
    url := "http://restapi3.apiary.io/notes"
    fmt.Println("URL:>", url)

    var jsonStr = []byte(`{"title":"Buy cheese and bread for breakfast."}`)
    req, err := http.NewRequest("POST", url, bytes.NewBuffer(jsonStr))
    req.Header.Set("X-Custom-Header", "myvalue")
    req.Header.Set("Content-Type", "application/json")

    client := &http.Client{}
    resp, err := client.Do(req)
    if err != nil {
        panic(err)
    }
    defer resp.Body.Close()

    fmt.Println("response Status:", resp.Status)
    fmt.Println("response Headers:", resp.Header)
    body, _ := ioutil.ReadAll(resp.Body)
    fmt.Println("response Body:", string(body))
}

There is also read_csv in Pandas, which is fast and supports non-comma column separators and automatic typing by column:

import pandas as pd
df = pd.read_csv('your_file',sep='\t')

It can be converted to a NumPy array if you prefer that type with:

import numpy as np
arr = np.array(df)

This is by far the easiest and most mature text import approach I've come across.

In Chrome, go to options (Customize and Control, the 3 dots/bars at top right) ---> More Tools ---> save page as

save page as  
filename     : any_name.html 
save as type : webpage complete.

Then you will get any_name.html and any_name folder.

This trick also suitable, but in this case align properties (middle, bottom etc.) won't be working.

<td style="display: block; position: relative;">
</td>

You should remove web middleware from routes.php. Adding web middleware manually causes session and request related problems in Laravel 5.2.27 and higher.

If it didn't help (still, keep routes.php without web middleware), you can try little bit different approach:

return redirect()->back()->with('message', 'IT WORKS!');

Displaying message if it exists:

@if(session()->has('message'))
    <div class="alert alert-success">
        {{ session()->get('message') }}
    </div>
@endif

got it resolved:

uninstall the entire android studio

uninstalling android with the following commands

Thanks Sanoj, that worked for me.
However iOS does not support "onbeforeunload" on iPhone. Workaround for me was to set localStorage with js:

<button onclick="myFunction()">Click me</button>

<script>
document.addEventListener("DOMContentLoaded", function(event) { 
            var scrollpos = localStorage.getItem('scrollpos');
            if (scrollpos) window.scrollTo(0, scrollpos);
        });
function myFunction() {
  localStorage.setItem('scrollpos', window.scrollY);
  location.reload(); 
}
</script>

You can use OnClientClick event to call a JavaScript function:

<asp:Button ID="Button1" runat="server" Text="Button" onclientclick='redirect()' />

JavaScript code:

function redirect() {
  location.href = 'page.aspx';
}

But i think the best would be to style a hyperlink with css.

Example :

.button {
  display: block;
  height: 25px;
  background: #f1f1f1;
  padding: 10px;
  text-align: center;
  border-radius: 5px;
  border: 1px solid #e1e1e2;
  color: #000;
  font-weight: bold;
}

While the op does not explicitly state they are using jquery ui and bootstrap together, an identical problem happens if you do. You can resolve the problem by loading bootstrap (js) before jquery ui (js). However, that will cause problems with button state colors.

The final solution is to either use bootstrap or jquery ui, but not both. However, a workaround is:

    $('<div>dialog content</div>').dialog({
        title: 'Title',
        open: function(){
            var closeBtn = $('.ui-dialog-titlebar-close');
            closeBtn.append('<span class="ui-button-icon-primary ui-icon ui-icon-closethick"></span><span class="ui-button-text">close</span>');
        }
    });

Try this, it should work:

 python.exe -m pip install --upgrade https://storage.googleapis.com/tensorflow/mac/cpu/tensorflow-0.12.0-py3-none-any.whl

Right variant for .NET 4.5 +

C# code

public class VersionManager
{
    private static string filterString;

    public static string FilterString
    {
        get => filterString;
        set
        {
            if (filterString == value)
                return;

            filterString = value;

            StaticPropertyChanged?.Invoke(null, FilterStringPropertyEventArgs);
        }
    }

    private static readonly PropertyChangedEventArgs FilterStringPropertyEventArgs = new PropertyChangedEventArgs (nameof(FilterString));
    public static event PropertyChangedEventHandler StaticPropertyChanged;
}

XAML binding (attention to braces they are (), not {})

<TextBox Text="{Binding Path=(yournamespace:VersionManager.FilterString)}" />

If non of above works for you, then it is worth to check if you have any packages under Preference > Editor > Code Style > Java > Imports > Packages to Use Import with "*"

Your approach is OK

Maybe slightly clearer (to me anyway!)

UPDATE
  T1
SET
  [Description] = t2.[Description]
FROM
   Table1 T1
   JOIN
   [Table2] t2 ON t2.[ID] = t1.DescriptionID

Both this and your query should run the same performance wise because it is the same query, just laid out differently.

You can now use the ZipArchive class (System.IO.Compression.ZipArchive), available from .NET 4.5

You have to add System.IO.Compression as a reference.

Example: Generating a zip of PDF files

using (var fileStream = new FileStream(@"C:\temp\temp.zip", FileMode.CreateNew))
{
    using (var archive = new ZipArchive(fileStream, ZipArchiveMode.Create, true))
    {
        foreach (var creditNumber in creditNumbers)
        {
            var pdfBytes = GeneratePdf(creditNumber);
            var fileName = "credit_" + creditNumber + ".pdf";
            var zipArchiveEntry = archive.CreateEntry(fileName, CompressionLevel.Fastest);
            using (var zipStream = zipArchiveEntry.Open())
                zipStream.Write(pdfBytes, 0, pdfBytes.Length);
            }
        }
    }
}

from selenium.webdriver.support.ui import Select
driver = webdriver.Ie(".\\IEDriverServer.exe")
driver.get("https://test.com")
select = Select(driver.find_element_by_xpath("""//input[@name='n_name']"""))
select.select_by_index(2)

It will work fine

Since the quickest, shortest answer is in a comment (from Jeff) and has a typo, here it is corrected and in full:

sales['time_hour'] = pd.DatetimeIndex(sales['timestamp']).hour

CSS Level 4 side note: Generally, the reason you'd want to be able to convert Hex to RGB is for the alpha channel, in which case you can soon do that with CSS4 by adding a trailing hex. Example: #FF8800FF or #f80f for fully transparent orange.

That aside, the code below answers both the questions in a single function, going from and to another. This accepts an optional alpha channel, supports both string an array formats, parses 3,4,6,7 character hex's, and rgb/a complete or partial strings (with exception of percent-defined rgb/a values) without a flag.

(Replace the few ES6 syntaxes if supporting IE)

In a line:

function rgbaHex(c,a,i){return(Array.isArray(c)||(typeof c==='string'&&/,/.test(c)))?((c=(Array.isArray(c)?c:c.replace(/[\sa-z\(\);]+/gi,'').split(',')).map(s=>parseInt(s).toString(16).replace(/^([a-z\d])$/i,'0$1'))),'#'+c[0]+c[1]+c[2]):(c=c.replace(/#/,''),c=c.length%6?c.replace(/(.)(.)(.)/,'$1$1$2$2$3$3'):c,a=parseFloat(a)||null,`rgb${a?'a':''}(${[(i=parseInt(c,16))>>16&255,i>>8&255,i&255,a].join().replace(/,$/,'')})`);}

Readable version:

function rgbaHex(c, a) {
    // RGBA to Hex
    if (Array.isArray(c) || (typeof c === 'string' && /,/.test(c))) {
        c = Array.isArray(c) ? c : c.replace(/[\sa-z\(\);]+/gi, '').split(',');
        c = c.map(s => window.parseInt(s).toString(16).replace(/^([a-z\d])$/i, '0$1'));

        return '#' + c[0] + c[1] + c[2];
    }
    // Hex to RGBA
    else {
        c = c.replace(/#/, '');
        c = c.length % 6 ? c.replace(/(.)(.)(.)/, '$1$1$2$2$3$3') : c;
        c = window.parseInt(c, 16);

        a = window.parseFloat(a) || null;

        const r = (c >> 16) & 255;
        const g = (c >> 08) & 255;
        const b = (c >> 00) & 255;

        return `rgb${a ? 'a' : ''}(${[r, g, b, a].join().replace(/,$/,'')})`;
    }
}

Usages:

rgbaHex('#a8f')

rgbaHex('#aa88ff')

rgbaHex('#A8F')

rgbaHex('#AA88FF')
