It is an old topic, but for some people it might be useful:

        DataSet someDataSet = new DataSet();
        SqlDataAdapter adapt = new SqlDataAdapter();

        using(SqlConnection connection = new SqlConnection(ConnString))
        {
            connection.Open();
            SqlCommand comm1 = new SqlCommand("SELECT * FROM whateverTable", connection);
            SqlCommand comm2g = new SqlCommand("SELECT * FROM whateverTable WHERE condition = @0", connection);
            commProcessing.Parameters.AddWithValue("@0", "value");
            someDataSet.Tables.Add("Table1");
            someDataSet.Tables.Add("Table2");

            adapt.SelectCommand = comm1;
            adapt.Fill(someDataSet.Tables["Table1"]);
            adapt.SelectCommand = comm2;
            adapt.Fill(someDataSet.Tables["Table2"]);
        }

I would suggest writing an extension method for this:

public static IEnumerable<T> Select<T>(this IDataReader reader,
                                       Func<IDataReader, T> projection)
{
    while (reader.Read())
    {
        yield return projection(reader);
    }
}

You can then use LINQ's ToList() method to convert that into a List<T> if you want, like this:

using (IDataReader reader = ...)
{
    List<Customer> customers = reader.Select(r => new Customer {
        CustomerId = r["id"] is DBNull ? null : r["id"].ToString(),
        CustomerName = r["name"] is DBNull ? null : r["name"].ToString() 
    }).ToList();
}

I would actually suggest putting a FromDataReader method in Customer (or somewhere else):

public static Customer FromDataReader(IDataReader reader) { ... }

That would leave:

using (IDataReader reader = ...)
{
    List<Customer> customers = reader.Select<Customer>(Customer.FromDataReader)
                                     .ToList();
}

(I don't think type inference would work in this case, but I could be wrong...)

        /// <summary>
    /// Returns a new conContractorEntity instance filled with the DataReader's current record data
    /// </summary>
    protected virtual conContractorEntity GetContractorFromReader(IDataReader reader)
    {
        return new conContractorEntity()
        {
            ConId = reader["conId"].ToString().Length > 0 ? int.Parse(reader["conId"].ToString()) : 0,
            ConEmail = reader["conEmail"].ToString(),
            ConCopyAdr = reader["conCopyAdr"].ToString().Length > 0 ? bool.Parse(reader["conCopyAdr"].ToString()) : true,
            ConCreateTime = reader["conCreateTime"].ToString().Length > 0 ? DateTime.Parse(reader["conCreateTime"].ToString()) : DateTime.MinValue
        };
    }

OR

        /// <summary>
    /// Returns a new conContractorEntity instance filled with the DataReader's current record data
    /// </summary>
    protected virtual conContractorEntity GetContractorFromReader(IDataReader reader)
    {
        return new conContractorEntity()
        {
            ConId = GetValue<int>(reader["conId"]),
            ConEmail = reader["conEmail"].ToString(),
            ConCopyAdr = GetValue<bool>(reader["conCopyAdr"], true),
            ConCreateTime = GetValue<DateTime>(reader["conCreateTime"])
        };
    }

// Base methods
        protected T GetValue<T>(object obj)
    {
        if (typeof(DBNull) != obj.GetType())
        {
            return (T)Convert.ChangeType(obj, typeof(T));
        }
        return default(T);
    }

    protected T GetValue<T>(object obj, object defaultValue)
    {
        if (typeof(DBNull) != obj.GetType())
        {
            return (T)Convert.ChangeType(obj, typeof(T));
        }
        return (T)defaultValue;
    }

There is no event raised when a class changes. The alternative is to manually raise an event when you programatically change the class:

$someElement.on('event', function() {
    $('#myDiv').addClass('submission-ok').trigger('classChange');
});

// in another js file, far, far away
$('#myDiv').on('classChange', function() {
     // do stuff
});

UPDATE

This question seems to be gathering some visitors, so here is an update with an approach which can be used without having to modify existing code using the new MutationObserver:

var $div = $("#foo");_x000D_
var observer = new MutationObserver(function(mutations) {_x000D_
  mutations.forEach(function(mutation) {_x000D_
    if (mutation.attributeName === "class") {_x000D_
      var attributeValue = $(mutation.target).prop(mutation.attributeName);_x000D_
      console.log("Class attribute changed to:", attributeValue);_x000D_
    }_x000D_
  });_x000D_
});_x000D_
observer.observe($div[0], {_x000D_
  attributes: true_x000D_
});_x000D_
_x000D_
$div.addClass('red');

.red { color: #C00; }

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<div id="foo" class="bar">#foo.bar</div>

Be aware that the MutationObserver is only available for newer browsers, specifically Chrome 26, FF 14, IE 11, Opera 15 and Safari 6. See MDN for more details. If you need to support legacy browsers then you will need to use the method I outlined in my first example.

I've used these codes:

HTML:

<a id="delete-button">Delete</a>

jQuery:

<script>
$("#delete-button").click(function(){
    if(confirm("Are you sure you want to delete this?")){
        $("#delete-button").attr("href", "query.php?ACTION=delete&ID='1'");
    }
    else{
        return false;
    }
});
</script>

These codes works for me, but I'm not really sure if this is proper. What do you think?

I had come across this problem many times. There is cl.exe but for some strange reason pip couldn't find it, even if we run the command from the bin folder where cl.exe is present. Try using conda installer, it worked fine for me.

As you can see in the following image, pip is not able to find the cl.exe. Then I tried installing using conda

And to my surprise it gets installed without an error once you have the right version of vs cpp build tools installed, i.e. v14.0 in the right directory.

Continuing with Mecki's suggestion, this article pthread mutex vs pthread spinlock on Alexander Sandler's blog, Alex on Linux shows how the spinlock & mutexes can be implemented to test the behavior using #ifdef.

However, be sure to take the final call based on your observation, understanding as the example given is an isolated case, your project requirement, environment may be entirely different.

you need to call thread.isAlive()to find out if the thread is still running

From Implementing toString:

public String toString() {
  StringBuilder result = new StringBuilder();
  String newLine = System.getProperty("line.separator");

  result.append( this.getClass().getName() );
  result.append( " Object {" );
  result.append(newLine);

  //determine fields declared in this class only (no fields of superclass)
  Field[] fields = this.getClass().getDeclaredFields();

  //print field names paired with their values
  for ( Field field : fields  ) {
    result.append("  ");
    try {
      result.append( field.getName() );
      result.append(": ");
      //requires access to private field:
      result.append( field.get(this) );
    } catch ( IllegalAccessException ex ) {
      System.out.println(ex);
    }
    result.append(newLine);
  }
  result.append("}");

  return result.toString();
}

You need to set the binding context of the ToolStripComboBox.ComboBox.

Here is a slightly modified version of the code that I have just recreated using Visual Studio. The menu item combo box is called toolStripComboBox1 in my case. Note the last line of code to set the binding context.

I noticed that if the combo is in the visible are of the toolstrip, the binding works without this but not when it is in a drop-down. Do you get the same problem?

If you can't get this working, drop me a line via my contact page and I will send you the project. You won't be able to load it using SharpDevelop but will with C# Express.

var languages = new string[2];
languages[0] = "English";
languages[1] = "German";

DataSet myDataSet = new DataSet();

// --- Preparation
DataTable lTable = new DataTable("Lang");
DataColumn lName = new DataColumn("Language", typeof(string));
lTable.Columns.Add(lName);

for (int i = 0; i < languages.Length; i++)
{
    DataRow lLang = lTable.NewRow();
    lLang["Language"] = languages[i];
    lTable.Rows.Add(lLang);
}
myDataSet.Tables.Add(lTable);

toolStripComboBox1.ComboBox.DataSource = myDataSet.Tables["Lang"].DefaultView;
toolStripComboBox1.ComboBox.DisplayMember = "Language";

toolStripComboBox1.ComboBox.BindingContext = this.BindingContext;

Here's some examples that demonstrate setting and detecting timeouts in jQuery's old and new paradigmes.

Live Demo

Promise with jQuery 1.8+

Promise.resolve(
  $.ajax({
    url: '/getData',
    timeout:3000 //3 second timeout
  })
).then(function(){
  //do something
}).catch(function(e) {
  if(e.statusText == 'timeout')
  {     
    alert('Native Promise: Failed from timeout'); 
    //do something. Try again perhaps?
  }
});

jQuery 1.8+

$.ajax({
    url: '/getData',
    timeout:3000 //3 second timeout
}).done(function(){
    //do something
}).fail(function(jqXHR, textStatus){
    if(textStatus === 'timeout')
    {     
        alert('Failed from timeout'); 
        //do something. Try again perhaps?
    }
});?

jQuery <= 1.7.2

$.ajax({
    url: '/getData',
    error: function(jqXHR, textStatus){
        if(textStatus === 'timeout')
        {     
             alert('Failed from timeout');         
            //do something. Try again perhaps?
        }
    },
    success: function(){
        //do something
    },
    timeout:3000 //3 second timeout
});

Notice that the textStatus param (or jqXHR.statusText) will let you know what the error was. This may be useful if you want to know that the failure was caused by a timeout.

error(jqXHR, textStatus, errorThrown)

A function to be called if the request fails. The function receives three arguments: The jqXHR (in jQuery 1.4.x, XMLHttpRequest) object, a string describing the type of error that occurred and an optional exception object, if one occurred. Possible values for the second argument (besides null) are "timeout", "error", "abort", and "parsererror". When an HTTP error occurs, errorThrown receives the textual portion of the HTTP status, such as "Not Found" or "Internal Server Error." As of jQuery 1.5, the error setting can accept an array of functions. Each function will be called in turn. Note: This handler is not called for cross-domain script and JSONP requests.

Here's a nifty trick that doesn't use a semaphore:

dispatch_queue_t serialQ = dispatch_queue_create("serialQ", DISPATCH_QUEUE_SERIAL);
dispatch_async(serialQ, ^
{
    [object doSomething];
});
dispatch_sync(serialQ, ^{ });

What you do is wait using dispatch_sync with an empty block to Synchronously wait on a serial dispatch queue until the A-Synchronous block has completed.

You can use an object as a map:

  var hasName = ({
        "true"  : "Y",
        "false" : "N"
  })[name];

This also scales nicely for many options

  var hasName = ({
        "true"          : "Y",
        "false"         : "N",
        "fileNotFound"  : "O"
  })[name];

(Bonus point for people getting the reference)

Note: you should use actual booleans instead of the string value "true" for your variables indicating truth values.

You are importing from package "sub". start.py is not itself in a package even if there is a __init__.py present.

You would need to start your program from one directory over parent.py:

./start.py

./pkg/__init__.py
./pkg/parent.py
./pkg/sub/__init__.py
./pkg/sub/relative.py

With start.py:

import pkg.sub.relative

Now pkg is the top level package and your relative import should work.

If you want to stick with your current layout you can just use import parent. Because you use start.py to launch your interpreter, the directory where start.py is located is in your python path. parent.py lives there as a separate module.

You can also safely delete the top level __init__.py, if you don't import anything into a script further up the directory tree.

I also got a requirement to calculate the process time of some code lines. So I tried the approved answer and I got this warning.

DeprecationWarning: time.clock has been deprecated in Python 3.3 and will be removed from Python 3.8: use time.perf_counter or time.process_time instead

So python will remove time.clock() from Python 3.8. You can see more about it from issue #13270. This warning suggest two function instead of time.clock(). In the documentation also mention about this warning in-detail in time.clock() section.

Deprecated since version 3.3, will be removed in version 3.8: The behaviour of this function depends on the platform: use perf_counter() or process_time() instead, depending on your requirements, to have a well defined behaviour.

Let's look at in-detail both functions.

• time.perf_counter()

Return the value (in fractional seconds) of a performance counter, i.e. a clock with the highest available resolution to measure a short duration. It does include time elapsed during sleep and is system-wide. The reference point of the returned value is undefined, so that only the difference between the results of consecutive calls is valid.

New in version 3.3.

So if you want it as nanoseconds, you can use time.perf_counter_ns() and if your code consist with time.sleep(secs), it will also count. Ex:-

import time


def func(x):
    time.sleep(5)
    return x * x


lst = [1, 2, 3]
tic = time.perf_counter()
print([func(x) for x in lst])
toc = time.perf_counter()
print(toc - tic)

# [1, 4, 9]
# 15.0041916 --> output including 5 seconds sleep time

• time.process_time()

Return the value (in fractional seconds) of the sum of the system and user CPU time of the current process. It does not include time elapsed during sleep. It is process-wide by definition. The reference point of the returned value is undefined, so that only the difference between the results of consecutive calls is valid.

New in version 3.3.

So if you want it as nanoseconds, you can use time.process_time_ns() and if your code consist with time.sleep(secs), it won't count. Ex:-

import time


def func(x):
    time.sleep(5)
    return x * x


lst = [1, 2, 3]
tic = time.process_time()
print([func(x) for x in lst])
toc = time.process_time()
print(toc - tic)

# [1, 4, 9]
# 0.0 --> output excluding 5 seconds sleep time

Please note both time.perf_counter_ns() and time.process_time_ns() come up with Python 3.7 onward.

There is no native version of Visual Studio for Mac OS X.

Almost all versions of Visual Studio have a Garbage rating on Wine's application database, so Wine isn't an option either, sadly.

This is a really obvious answer/rookie mistake, but I thought I would just put it here in case it might help someone. So my structure was that a had a Website in IIS with the frontend as one application underneath the website and the backend was the other. The backend application had six seperate api applications sitting beneath it. I had forgotten to convert each of the api folders to applications within IIS and of course this was causing the routes to my api endpoints to return a 404.0 error.

My Point: Check the simple stuff first! Make sure that you have converted all folders to applications in IIS where that is required for your website to function correctly.

I found the path of the SDK (Preferences* ? Android ? SDK Location) was the cause. My SDK path was the following:

C:\Program Files (x86)\Android\android-sdk

The spaces in the path is the problem. To get it to work, you must change Program Files (x86) to Progra~2

The complete right path is C:\Progra~2\Android\android-sdk.

Now it should work.

Use Entry.insert. For example:

try:
    from tkinter import *  # Python 3.x
except Import Error:
    from Tkinter import *  # Python 2.x

root = Tk()
e = Entry(root)
e.insert(END, 'default text')
e.pack()
root.mainloop()

Or use textvariable option:

try:
    from tkinter import *  # Python 3.x
except Import Error:
    from Tkinter import *  # Python 2.x

root = Tk()
v = StringVar(root, value='default text')
e = Entry(root, textvariable=v)
e.pack()
root.mainloop()

\n is used for Unix systems (including Linux, and OSX).

\r\n is mainly used on Windows.

\r is used on really old Macs.

PHP_EOL constant is used instead of these characters for portability between platforms.

My friend, you need to create those corresponding branches locally first, in order to check-out to those other two branches, using this line of code

git branch test-branch  

and

git branch change-the-title

then only you will be able to do git checkout to those branches

Also after creating each branch, take latest changes of those particular branches by using git pull origin branch_name as shown in below code

git branch test-branch
git checkout test-branch
git pull origin test-branch

and for other branch named change-the-title run following code =>

git branch change-the-title
git checkout change-the-title
git pull origin change-the-title

Happy programming :)

You can't access outside private fields of a class. private fields are starting with __ . for example -

class car:
    def __init__(self):
        self.__updatesoftware()

    def drive(self):
        print("driving")

    def __updatesoftware(self):
        print("updating software:")

obj = car()
obj.drive()  
obj.__updatesoftware()  ## here it will throw an error because 

__updatesoftware is an private method.

Your exception says it all "Connection reset". The connection between your java process and the db server was lost, which could have happened for almost any reason(like network issues). The SQLRecoverableException just means that its recoverable, but the root cause is connection reset.

You need to link with the math library:

gcc -o sphere sphere.c -lm

The error you are seeing: error: ld returned 1 exit status is from the linker ld (part of gcc that combines the object files) because it is unable to find where the function pow is defined.

Including math.h brings in the declaration of the various functions and not their definition. The def is present in the math library libm.a. You need to link your program with this library so that the calls to functions like pow() are resolved.

Array notaion is the best way of combining styles in react native.

This shows how to combine 2 Style objects,

<Text style={[styles.base, styles.background]} >Test </Text>

this shows how to combine Style object and property,

<Text style={[styles.base, {color: 'red'}]} >Test </Text>

This will work on any react native application.

I had a similar error & this is what I found.

My environment details were as below: steps followed at my end

c:\>pip --version
pip 20.0.2 from c:\python37_64\lib\site-packages\pip (python 3.7)

C:\>python --version
Python 3.7.6

As per the documentation, apparently, python 3.7 already has the pickle package. So it does not require any additional download. I checked with the following command to make sure & it worked.

C:\Python\Experiements>python
Python 3.7.6 (tags/v3.7.6:43364a7ae0, Dec 19 2019, 00:42:30) [MSC v.1916 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import pickle
>>>

So, pip install pickle not required for python v3.7 for sure

Most databases have a native UUID type these days to make working with them easier. If yours doesn't, they're just 128-bit numbers, so you can use BINARY(16), and if you need the text format frequently, e.g. for troubleshooting, then add a calculated column to generate it automatically from the binary column. There is no good reason to store the (much larger) text form.

I have seen some solutions here worth noting, as Omer Eldan posted. but here follows. ASP C#

using System.Data;
using System.Web.UI.HtmlControls;

public static Table DataTableToHTMLTable(DataTable dt, bool includeHeaders)
{
    Table tbl = new Table();
    TableRow tr = null;
    TableCell cell = null;

    int rows = dt.Rows.Count;
    int cols = dt.Columns.Count;

    if (includeHeaders)
    {
        TableHeaderRow htr = new TableHeaderRow();
        TableHeaderCell hcell = null;
        for (int i = 0; i < cols; i++)
        {
            hcell = new TableHeaderCell();
            hcell.Text = dt.Columns[i].ColumnName.ToString();
            htr.Cells.Add(hcell);
        }
        tbl.Rows.Add(htr);
    }

    for (int j = 0; j < rows; j++)
    {
        tr = new TableRow();
        for (int k = 0; k < cols; k++)
        {
            cell = new TableCell();
            cell.Text = dt.Rows[j][k].ToString();
            tr.Cells.Add(cell);
        }
        tbl.Rows.Add(tr);
    }
    return tbl;
}

why this solution? Because you can easily just add this to a panel ie:

panel.Controls.Add(DataTableToHTMLTable(dtExample,true));

Second question , why do you have one column datatables and not just array's? Are you sure that these DataTables are uniform, because if the data is jagged then it's no use. If You really have to join these DataTables, there is many examples of Linq operations, or just use (beware though of same name columns as this will conflict in both linq operations and this solution if not handled):

public DataTable joinUniformTable(DataTable dt1, DataTable dt2)
{
    int dt2ColsCount = dt2.Columns.Count;
    int dt1lRowsCount = dt1.Rows.Count;

    DataColumn column;
    for (int i = 0; i < dt2ColsCount; i++)
    {
        column = new DataColumn();
        string colName = dt2.Columns[i].ColumnName;
        System.Type colType = dt2.Columns[i].DataType;
        column.ColumnName = colName;
        column.DataType = colType;
        dt1.Columns.Add(column);

        for (int j = 0; j < dt1lRowsCount; j++)
        {
            dt1.Rows[j][colName] = dt2.Rows[j][colName];
        }
    }
    return dt1;
}

and your solution would look something like:

panel.Controls.Add(DataTableToHTMLTable(joinUniformTable(joinUniformTable(LivDT,BathDT),BedDT),true));

interpret the rest, and have fun.

CPython (the classic and prevalent implementation of Python) can't have more than one thread executing Python bytecode at the same time. This means compute-bound programs will only use one core. I/O operations and computing happening inside C extensions (such as numpy) can operate simultaneously.

Other implementation of Python (such as Jython or PyPy) may behave differently, I'm less clear on their details.

The usual recommendation is to use many processes rather than many threads.

Some people have asked: how can the singleton return a null pointer? I'm answering that question. (I cannot answer in a comment because I need to post code.)

It may return null in between two events: (1) the class is loaded, and (2) the object of this class is created. Here's an example:

class X {
    static X xinstance;
    static Y yinstance = Y.yinstance;
    X() {xinstance=this;}
}
class Y {
    static X xinstance = X.xinstance;
    static Y yinstance;
    Y() {yinstance=this;}
}

public class A {
    public static void main(String[] p) {
    X x = new X();
    Y y = new Y();
    System.out.println("x:"+X.xinstance+" y:"+Y.yinstance);
    System.out.println("x:"+Y.xinstance+" y:"+X.yinstance);
    }
}

Let's run the code:

$ javac A.java 
$ java A
x:X@a63599 y:Y@9036e
x:null y:null

The second line shows that Y.xinstance and X.yinstance are null; they are null because the variables X.xinstance ans Y.yinstance were read when they were null.

Can this be fixed? Yes,

class X {
    static Y y = Y.getInstance();
    static X theinstance;
    static X getInstance() {if(theinstance==null) {theinstance = new X();} return theinstance;}
}
class Y {
    static X x = X.getInstance();
    static Y theinstance;
    static Y getInstance() {if(theinstance==null) {theinstance = new Y();} return theinstance;}
}

public class A {
    public static void main(String[] p) {
    System.out.println("x:"+X.getInstance()+" y:"+Y.getInstance());
    System.out.println("x:"+Y.x+" y:"+X.y);
    }
}

and this code shows no anomaly:

$ javac A.java 
$ java A
x:X@1c059f6 y:Y@152506e
x:X@1c059f6 y:Y@152506e

BUT this is not an option for the Android Application object: the programmer does not control the time when it is created.

Once again: the difference between the first example and the second one is that the second example creates an instance if the static pointer is null. But a programmer cannot create the Android application object before the system decides to do it.

UPDATE

One more puzzling example where initialized static fields happen to be null.

Main.java:

enum MyEnum {
    FIRST,SECOND;
    private static String prefix="<", suffix=">";
    String myName;
    MyEnum() {
        myName = makeMyName();
    }
    String makeMyName() {
        return prefix + name() + suffix;
    }
    String getMyName() {
        return myName;
    }
}
public class Main {
    public static void main(String args[]) {
        System.out.println("first: "+MyEnum.FIRST+" second: "+MyEnum.SECOND);
        System.out.println("first: "+MyEnum.FIRST.makeMyName()+" second: "+MyEnum.SECOND.makeMyName());
        System.out.println("first: "+MyEnum.FIRST.getMyName()+" second: "+MyEnum.SECOND.getMyName());
    }
}

And you get:

$ javac Main.java
$ java Main
first: FIRST second: SECOND
first: <FIRST> second: <SECOND>
first: nullFIRSTnull second: nullSECONDnull

Note that you cannot move the static variable declaration one line upper, the code will not compile.

var objDiv = document.getElementById("divExample");
objDiv.scrollTop = objDiv.scrollHeight;

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

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

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

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

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

java -version

You will see something like this:

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

Then check the following:

javac -version

You will see something like this:

javac 1.7.0_79

Just a demo for the question.

class MyClass:

    def __init__(self):
        print('__init__ is the constructor for a class')

    def __del__(self):
        print('__del__ is the destructor for a class')

    def __enter__(self):
        print('__enter__ is for context manager')
        return self

    def __exit__(self, exc_type, exc_value, traceback):
        print('__exit__ is for context manager')

    def greeting(self):
        print('hello python')


if __name__ == '__main__':
    with MyClass() as mycls:
        mycls.greeting()

$ python3 class.objects_instantiation.py
__init__ is the constructor for a class
__enter__ is for context manager
hello python
__exit__ is for context manager
__del__ is the destructor for a class

Try this:

$str = '123456789';
$char_array = preg_split('//', $str, -1, PREG_SPLIT_NO_EMPTY);

The error says "The index is out of range". That means you were trying to index an object with a value that was not valid. If you have two books, and I ask you to give me your third book, you will look at me funny. This is the computer looking at you funny. You said - "create a collection". So it did. But initially the collection is empty: not only is there nothing in it - it has no space to hold anything. "It has no hands".

Then you said "the first element of the collection is now 'ItemID'". And the computer says "I never was asked to create space for a 'first item'." I have no hands to hold this item you are giving me.

In terms of your code, you created a view, but never specified the size. You need a

dataGridView1.ColumnCount = 5;

Before trying to access any columns. Modify

DataGridView dataGridView1 = new DataGridView();

dataGridView1.Columns[0].Name = "ItemID";

to

DataGridView dataGridView1 = new DataGridView();
dataGridView1.ColumnCount = 5;
dataGridView1.Columns[0].Name = "ItemID";

See http://msdn.microsoft.com/en-us/library/system.windows.forms.datagridview.columncount.aspx

It depends on (a) how attached you are to the number 7 as opposed to, say, Lemons, and (b) whether any of your file names contain newlines (and whether you're willing to rename them if they do).

There are many ways to deal with it, but some of them are:

mplayer Lemon*.mp3

find . -name 'Lemon*.mp3' -exec mplayer {} ';'

i=0
for mp3 in *.mp3
do
    i=$((i+1))
    [ $i = 7 ] && mplayer "$mp3"
done

for mp3 in *.mp3
do
    case "$mp3" in
    (Lemon*) mplayer "$mp3";;
    esac
done

i=0
find . -name *.mp3 |
while read mp3
do
    i=$((i+1))
    [ $i = 7 ] && mplayer "$mp3"
done

The read loop doesn't work if file names contain newlines; the others work correctly even with newlines in the names (let alone spaces). For my money, if you have file names containing a newline, you should rename the file without the newline. Using the double quotes around the file name is key to the loops working correctly.

If you have GNU find and GNU xargs (or FreeBSD (*BSD?), or Mac OS X), you can also use the -print0 and -0 options, as in:

find . -name 'Lemon*.mp3' -print0 | xargs -0 mplayer

This works regardless of the contents of the name (the only two characters that cannot appear in a file name are slash and NUL, and the slash causes no problems in a file path, so using NUL as the name delimiter covers everything). However, if you need to filter out the first 6 entries, you need a program that handles 'lines' ended by NUL instead of newline...and I'm not sure there are any.

The first is by far the simplest for the specific case on hand; however, it may not generalize to cover your other scenarios that you've not yet listed.

You can move to desired activity on button click. just add this line.

android:onClick="sendMessage"

xml:

 <Button
        android:id="@+id/button1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:onClick="sendMessage"
        android:text="@string/button" />

In your main activity just add this method:

public void sendMessage(View view) {
    Intent intent = new Intent(FromActivity.this, ToActivity.class);
    startActivity(intent);
}

And the most important thing: don't forget to define your activity in manifest.xml

 <activity>
      android:name=".ToActivity"
      android:label="@string/app_name">          
 </activity>

I simplification for Science_Fiction's answer I think is to use the exclusive or function so you can just have:

if(checkbox1.checked ^ checkbox2.checked)
{
//do stuff
}

That is assuming you want to do the same thing for both situations.

If you already have it as a DateTime, use:

string x = dt.ToString("yyyy-MM-dd");

See the MSDN documentation for more details. You can specify CultureInfo.InvariantCulture to enforce the use of Western digits etc. This is more important if you're using MMM for the month name and similar things, but it wouldn't be a bad idea to make it explicit:

string x = dt.ToString("yyyy-MM-dd", CultureInfo.InvariantCulture);

If you have a string to start with, you'll need to parse it and then reformat... of course, that means you need to know the format of the original string.

Here's the briefest explanation:

A Turing Complete system means a system in which a program can be written that will find an answer (although with no guarantees regarding runtime or memory).

So, if somebody says "my new thing is Turing Complete" that means in principle (although often not in practice) it could be used to solve any computation problem.

Sometimes it's a joke... a guy wrote a Turing Machine simulator in vi, so it's possible to say that vi is the only computational engine ever needed in the world.

For 1D array, numpy.correlate is faster than scipy.signal.correlate, under different sizes, I see a consistent 5x peformance gain using numpy.correlate. When two arrays are of similar size (the bright line connecting the diagonal), the performance difference is even more outstanding (50x +).

# a simple benchmark
res = []
for x in range(1, 1000):
    list_x = []
    for y in range(1, 1000): 

        # generate different sizes of series to compare
        l1 = np.random.choice(range(1, 100), size=x)
        l2 = np.random.choice(range(1, 100), size=y)

        time_start = datetime.now()
        np.correlate(a=l1, v=l2)
        t_np = datetime.now() - time_start

        time_start = datetime.now()
        scipy.signal.correlate(in1=l1, in2=l2)
        t_scipy = datetime.now() - time_start

        list_x.append(t_scipy / t_np)
    res.append(list_x)
plt.imshow(np.matrix(res))

As default, scipy.signal.correlate calculates a few extra numbers by padding and that might explained the performance difference.

>> l1 = [1,2,3,2,1,2,3]
>> l2 = [1,2,3]
>> print(numpy.correlate(a=l1, v=l2))
>> print(scipy.signal.correlate(in1=l1, in2=l2))

[14 14 10 10 14]
[ 3  8 14 14 10 10 14  8  3]  # the first 3 is [0,0,1]dot[1,2,3]

I found out that you need to add the pointer eg:

div{
    cursor: url('cursorurl.png'), pointer;
}

you said that:

`mony = float(1234.5)
print(money)      #output is 1234.5
'${:,.2f}'.format(money)
print(money)

did not work.... Have you coded exactly that way? This should work (see the little difference):

money = float(1234.5)      #next you used format without printing, nor affecting value of "money"
amountAsFormattedString = '${:,.2f}'.format(money)
print( amountAsFormattedString )

Yes: list1 + list2. This gives a new list that is the concatenation of list1 and list2.

Support for TLS 1.0 and 1.1 was dropped for PyPI. If your system does not use a more recent version, it could explain your error.

Could you try reinstalling pip system-wide, to update your system dependencies to a newer version of TLS?

This seems to be related to Unable to install Python libraries

See Dominique Barton's answer:

Apparently pip is trying to access PyPI via HTTPS (which is encrypted and fine), but with an old (insecure) SSL version. Your system seems to be out of date. It might help if you update your packages.

On Debian-based systems I'd try:

apt-get update && apt-get upgrade python-pip

On Red Hat Linux-based systems:

yum update python-pip # (or python2-pip, at least on Red Hat Linux 7)

On Mac:

sudo easy_install -U pip

You can also try to update openssl separately.

Use the _ variable, as I learned when I asked this question, for example:

# A long way to do integer exponentiation
num = 2
power = 3
product = 1
for _ in xrange(power):
    product *= num
print product

Thanks for all help at this issue. I'll post here my solution:

Please review.

1. Permissions:

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

2. Get SD card root folder:

   Environment.getExternalStorageDirectory()
   

3. Delete file: this is an example on how to delete all empty folders in a root folder:

   public static void deleteEmptyFolder(File rootFolder){
       if (!rootFolder.isDirectory()) return;
   
       File[] childFiles = rootFolder.listFiles();
       if (childFiles==null) return;
       if (childFiles.length == 0){
           rootFolder.delete();
       } else {
           for (File childFile : childFiles){
               deleteEmptyFolder(childFile);
           }
       }
   }
   

4. Copy file:

   public static void copyFile(File src, File dst) throws IOException {
       FileInputStream var2 = new FileInputStream(src);
       FileOutputStream var3 = new FileOutputStream(dst);
       byte[] var4 = new byte[1024];
   
       int var5;
       while((var5 = var2.read(var4)) > 0) {
           var3.write(var4, 0, var5);
       }
   
       var2.close();
       var3.close();
   }
   

5. Move file = copy + delete source file

This will listen to the changed event. I have tried the answers from others but those did not work for me and finally, this one worked.

$('input:radio[name="postage"]').change(function(){
    if($(this).is(":checked")){
        alert("lksdahflk");
    }
});

Visual Studio 2020 version

In tasks.json file, (after you build and debug with the g++-9)

Add -std=c++2a for 2020 features (c++1z for 2017 features). Add -fconcepts to use concept keyword

"args": [
   "-std=c++2a",
   "-fconcepts",
   "-g",
   "${file}",
   "-o",
   "${fileDirname}/${fileBasenameNoExtension}"
],

now compile and you can use the 2020 features.

You can avoid the need for .bind(this) with an ES6 arrow function.

VK.api('users.get',{fields: 'photo_50'},(data) => {
        if(data.response){
            this.setState({ //the error happens here
                FirstName: data.response[0].first_name
            });
            console.info(this.state.FirstName);
        }

    });

The res.json() function should be sufficient for most cases.

app.get('/', (req, res) => res.json({ answer: 42 }));

The res.json() function converts the parameter you pass to JSON using JSON.stringify() and sets the Content-Type header to application/json; charset=utf-8 so HTTP clients know to automatically parse the response.

It's a ProgressDialog, with setIndeterminate(true).

From http://developer.android.com/guide/topics/ui/dialogs.html#ProgressDialog

ProgressDialog dialog = ProgressDialog.show(MyActivity.this, "", 
                    "Loading. Please wait...", true);

An indeterminate progress bar doesn't actually show a bar, it shows a spinning activity circle thing. I'm sure you know what I mean :)

You could store your JSON inside of an array and then insert the JSON data into the array with push

Check this out https://jsfiddle.net/cx2rk40e/2/

$(document).ready(function(){

  // using jQuery just to load function but will work without library.
  $( "button" ).on( "click", go );

  // Array of JSON we will append too.
  var jsonTest = [{
    "colour": "blue",
    "link": "http1"
  }]

  // Appends JSON to array with push. Then displays the data in alert.
  function go() {    
      jsonTest.push({"colour":"red", "link":"http2"});
      alert(JSON.stringify(jsonTest));    
    }

}); 

Result of JSON.stringify(jsonTest)

[{"colour":"blue","link":"http1"},{"colour":"red","link":"http2"}]

This answer maybe useful to users who wish to emulate a similar result.

If all you want is the file name without file extension

Dim fileNamesCol As New Collection
Dim MyFile As Variant  'Strings and primitive data types aren't allowed with collection

filePath = "c:\file directory" + "\"
MyFile = Dir$(filePath & "*.xlsx")
Do While MyFile <> ""
    fileNamesCol.Add (Replace(MyFile, ".xlsx", ""))
    MyFile = Dir$
Loop

To output to excel worksheet

Dim myWs As Worksheet: Set myWs = Sheets("SheetNameToDisplayTo")
Dim ic As Integer: ic = 1

For Each MyFile In fileNamesCol
    myWs.Range("A" & ic).Value = fileNamesCol(ic)
    ic = ic + 1
Next MyFile

Primarily based on the technique detailed here: https://wordmvp.com/FAQs/MacrosVBA/ReadFilesIntoArray.htm

"""
This function check if set is empty or not.
>>> c = set([])
>>> set_is_empty(c)
True

:param some_set: set to check if he empty or not.
:return True if empty, False otherwise.
"""
def set_is_empty(some_set):
    return some_set == set()

There's more than one way to do this obviously.

    # This will find files recursively (you can limit it by using some 'find' parameters. 
    # see the man pages
    # Final backslash required for exec example to work
    find . -name '*.gz' -exec gunzip '{}' \;

    # This will do it only in the current directory
    for a in *.gz; do gunzip $a; done

I'm sure there's other ways as well, but this is probably the simplest.

And to remove it, just do a rm -rf *.gz in the applicable directory

I'm using macOS Sierra (v10.12.1) Xcode v8.1 Swift 3.0.1 and here's what worked for me in ViewController.swift:

            //If you want handle the completion block than

};

On the Unity Editor open your project and:

1. Enable External option in Unity ? Preferences ? Packages ? Repository (only if Unity ver < 4.5)
2. Switch to Visible Meta Files in Edit ? Project Settings ? Editor ? Version Control Mode
3. Switch to Force Text in Edit ? Project Settings ? Editor ? Asset Serialization Mode
4. Save Scene and Project from File menu.
5. Quit Unity and then you can delete the Library and Temp directory in the project directory. You can delete everything but keep the Assets and ProjectSettings directory.

If you already created your empty git repo on-line (eg. github.com) now it's time to upload your code. Open a command prompt and follow the next steps:

cd to/your/unity/project/folder

git init

git add *

git commit -m "First commit"

git remote add origin [email protected]:username/project.git

git push -u origin master

You should now open your Unity project while holding down the Option or the Left Alt key. This will force Unity to recreate the Library directory (this step might not be necessary since I've seen Unity recreating the Library directory even if you don't hold down any key).

Finally have git ignore the Library and Temp directories so that they won’t be pushed to the server. Add them to the .gitignore file and push the ignore to the server. Remember that you'll only commit the Assets and ProjectSettings directories.

And here's my own .gitignore recipe for my Unity projects:

# =============== #
# Unity generated #

This worked brilliantly for me, :

 $query = "INSERT INTO `table` (...or put your preferred sql stuff)" 
 $result = mysqli_query($connect, $query); 
 if($result){
  // If everything runs fine with your sql query you will see a message and then the window
  //closes
        echo '<script language="javascript">';
        echo 'alert("Successful!")';
        echo '</script>';
        echo "<script>window.close();</script>";
        }
 else {
        echo '<script language="javascript">';
        echo 'alert("Problem with database or something!")';
        echo '</script>';           
        }

In browsers other than Internet Explorer, you can pass parameters to the function together after the delay:

var timeoutID = window.setTimeout(func, delay, [param1, param2, ...]);

So, you can do this:

var timeoutID = window.setTimeout(function (self) {
  console.log(self); 
}, 500, this);

This is better in terms of performance than a scope lookup (caching this into a variable outside of the timeout / interval expression), and then creating a closure (by using $.proxy or Function.prototype.bind).

The code to make it work in IEs from Webreflection:

/*@cc_on
(function (modifierFn) {
  // you have to invoke it as `window`'s property so, `window.setTimeout`
  window.setTimeout = modifierFn(window.setTimeout);
  window.setInterval = modifierFn(window.setInterval);
})(function (originalTimerFn) {
    return function (callback, timeout){
      var args = [].slice.call(arguments, 2);
      return originalTimerFn(function () { 
        callback.apply(this, args) 
      }, timeout);
    }
});

I was able to figure this out; it was a lot simpler then I thought. Under the WHM manager go to: Home >> Software >> EasyApache (Apache Update) >> There you have two options "Build Profile" or "Customize Based On Profile". I went Customize to keep my current config then followed the instructions on the page.

Eventually there was a place to add and remove php modules. There you will find ever module under the sun. Just select the one you want and rebuild the profile. It was really that simple.

I have a local install of tensorflow 1.15.0 (with tensorboard obviously included) on MacOS.

For me, the path to the relevant file within my user directory is Library/Python/3.7/lib/python/site-packages/tensorboard/main.py. So, which does not work for me, but you have to look for the file named main.py, which is weird since it apparently is named something else for other users.

Besides aws_access_key_id and aws_secret_access_key, I also added aws_session_token in credentials, it works for me

In my case I had to print a image inside a page. When I used the solution voted, I had 1 blank page and the other one showing the image. Hope it will help someone.

Here is the css I used:

I know it's a bit late, but I just came across this post and wanted to mention that I don't really see way everybody wants to do it in a difficult way... The problem here is just that the book class takes twoside as default, so, as gromgull said, just pass oneside as argument and it's solved.

It is better to parse the URL properly - this way you can handle http://.../file.doc?foo and http://.../foo.doc/file.exe correctly.

from urlparse import urlparse
import os
path = urlparse(url_string).path
ext = os.path.splitext(path)[1]
if ext in extensionsToCheck:
  print(url_string)

This piece of code helps.

Bitmap icon = BitmapFactory.decodeResource(context.getResources(),
                                           R.drawable.icon_resource);

Here a version where the image gets downloaded.

String name = c.getString(str_url);
URL url_value = new URL(name);
ImageView profile = (ImageView)v.findViewById(R.id.vdo_icon);
if (profile != null) {
    Bitmap mIcon1 =
        BitmapFactory.decodeStream(url_value.openConnection().getInputStream());
    profile.setImageBitmap(mIcon1);
}

In pymongo you can use:

db.mycollection.find({"IMAGE URL":{"$ne":None}});

Because pymongo represents mongo "null" as python "None".

ls -t list files by creation time not last modified time. Use ls -ltc if you want to list files by last modified time from last to first(top to bottom). Thus to list the last n: ls -ltc | head ${n}

Use ROW_NUMBER() instead. ROWNUM is a pseudocolumn and ROW_NUMBER() is a function. You can read about difference between them and see the difference in output of below queries:

SELECT * FROM (SELECT rownum, deptno, ename
           FROM scott.emp
        ORDER BY deptno
       )
 WHERE rownum <= 3
 /

ROWNUM    DEPTNO    ENAME
---------------------------
 7        10    CLARK
 14       10    MILLER
 9        10    KING


 SELECT * FROM 
 (
  SELECT deptno, ename
       , ROW_NUMBER() OVER (ORDER BY deptno) rno
  FROM scott.emp
 ORDER BY deptno
 )
WHERE rno <= 3
/

DEPTNO    ENAME    RNO
-------------------------
10    CLARK        1
10    MILLER       2
10    KING         3

All the references to Apache Commons are fine (and that is what most people use) but I think the Guava equivalent, Joiner, has a much nicer API.

You can do the simple join case with

Joiner.on(" and ").join(names)

but also easily deal with nulls:

Joiner.on(" and ").skipNulls().join(names);

or

Joiner.on(" and ").useForNull("[unknown]").join(names);

and (useful enough as far as I'm concerned to use it in preference to commons-lang), the ability to deal with Maps:

Map<String, Integer> ages = .....;
String foo = Joiner.on(", ").withKeyValueSeparator(" is ").join(ages);
// Outputs:
// Bill is 25, Joe is 30, Betty is 35

which is extremely useful for debugging etc.

Vue allows for you to specify a default prop value and type directly, by making props an object (see: https://vuejs.org/guide/components.html#Prop-Validation):

props: {
  year: {
    default: 2016,
    type: Number
  }
}

If the wrong type is passed then it throws an error and logs it in the console, here's the fiddle:

https://jsfiddle.net/cexbqe2q/

You can do it without setlocal, because of the setlocal command the variable won't survive an endlocal because it was created in setlocal. In this way the variable will be defined the right way.

To do that use this code:

set var1=A

set var2=B

set AB=hi

call set newvar=%%%var1%%var2%%%

echo %newvar% 

Note: You MUST use call before you set the variable or it won't work.

To handle rounding to any number of decimal places, a function with 2 lines of code will suffice for most needs. Here's some sample code to play with.

    var testNum = 134.9567654;
    var decPl = 2;
    var testRes = roundDec(testNum,decPl);  
    alert (testNum + ' rounded to ' + decPl + ' decimal places is ' + testRes);

    function roundDec(nbr,dec_places){
        var mult = Math.pow(10,dec_places);
        return Math.round(nbr * mult) / mult;
    }

Suggestion 1

When you add an object to $stateProvider.state that object is then passed with the state. So you can add additional properties which you can read later on when needed.

Example route configuration

$stateProvider
.state('public', {
    abstract: true,
    module: 'public'
})
.state('public.login', {
    url: '/login',
    module: 'public'
})
.state('tool', {
    abstract: true,
    module: 'private'
})
.state('tool.suggestions', {
    url: '/suggestions',
    module: 'private'
});

The $stateChangeStart event gives you acces to the toState and fromState objects. These state objects will contain the configuration properties.

Example check for the custom module property

$rootScope.$on('$stateChangeStart', function(e, toState, toParams, fromState, fromParams) {
    if (toState.module === 'private' && !$cookies.Session) {
        // If logged out and transitioning to a logged in page:
        e.preventDefault();
        $state.go('public.login');
    } else if (toState.module === 'public' && $cookies.Session) {
        // If logged in and transitioning to a logged out page:
        e.preventDefault();
        $state.go('tool.suggestions');
    };
});

I didn't change the logic of the cookies because I think that is out of scope for your question.

Suggestion 2

You can create a Helper to get you this to work more modular.

Value publicStates

myApp.value('publicStates', function(){
    return {
      module: 'public',
      routes: [{
        name: 'login', 
        config: { 
          url: '/login'
        }
      }]
    };
});

Value privateStates

myApp.value('privateStates', function(){
    return {
      module: 'private',
      routes: [{
        name: 'suggestions', 
        config: { 
          url: '/suggestions'
        }
      }]
    };
});

The Helper

myApp.provider('stateshelperConfig', function () {
  this.config = {
    // These are the properties we need to set
    // $stateProvider: undefined
    process: function (stateConfigs){
      var module = stateConfigs.module;
      $stateProvider = this.$stateProvider;
      $stateProvider.state(module, {
        abstract: true,
        module: module
      });
      angular.forEach(stateConfigs, function (route){
        route.config.module = module;
        $stateProvider.state(module + route.name, route.config);
      });
    }
  };

  this.$get = function () {
    return {
      config: this.config
    };
  };
});

Now you can use the helper to add the state configuration to your state configuration.

myApp.config(['$stateProvider', '$urlRouterProvider', 
    'stateshelperConfigProvider', 'publicStates', 'privateStates',
  function ($stateProvider, $urlRouterProvider, helper, publicStates, privateStates) {
    helper.config.$stateProvider = $stateProvider;
    helper.process(publicStates);
    helper.process(privateStates);
}]);

This way you can abstract the repeated code, and come up with a more modular solution.

Note: the code above isn't tested

Here's what I believe is the Swift equivalent:

if let data = NSData(contentsOfFile: filePath) {
   let length = data.length
   let byteData = malloc(length)
   memcmp(byteData, data.bytes, length)
}

This can be simplified by completely skipping the where object and the $users declaration. All you need is:

Code

get-content c:\scripts\users.txt | get-aduser -properties * | select displayname, office | export-csv c:\path\to\your.csv

public class One {

    private static One one = null;

    Map<String, String> configParameter = Collections.synchronizedMap(new HashMap<String, String>());

    private One() {
        ResourceBundle rb = ResourceBundle.getBundle("System", Locale.getDefault());

        Enumeration en = rb.getKeys();
        while (en.hasMoreElements()) {
            String key = (String) en.nextElement();
            String value = rb.getString(key);
            configParameter.put(key, value);

        }
    }

    public static One getInstance() {
        if (one == null) {
            one= new One();
        }

        return one;

    }

    public Map<String, String> getParameter() {

        return configParameter;
    }



    public static void main(String[] args) {
        String string = One.getInstance().getParameter().get("subin");
        System.out.println(string);

    }
}

Simply install rxjs-compat to solve the problem

npm i rxjs-compat --save-dev

And import it like below

import 'rxjs/Rx';

If you are working on localhost, create a separate APIkey for your development and then remove restrictions on that key so that your localhost can use it. Remember to not use this key on production, so you don't expose your key to hunters online.

I had the same issue and all attempts to get the restrictions working on my localhost environment was not successful until I created a separate apikey specifically for development and then removed its restrictions. However I don't use that key on production environment, and once am done with developments, I will delete the API key immediately.

I Know this post is late, but for people that will likely face this issue in the future, this is the best route to go.

When using more +n that Matt already mentioned, to avoid pauses in long files, try this:

more +1 myfile.txt > con

When you redirect the output from more, it doesn't pause - and here you redirect to the console. You can similarly redirect to some other file like this w/o the pauses of more if that's your desired end result. Use > to redirect to file and overwrite it if it already exists, or >> to append to an existing file. (Can use either to redirect to con.)

without disabling the selected value on submitting..

$('#selectID option:not(:selected)').prop('disabled', true);

If you use Jquery version lesser than 1.7
$('#selectID option:not(:selected)').attr('disabled', true);

It works for me..

You can use SET ECHO ON in the beginning of your script to achieve that, however, you have to specify your script using @ instead of < (also had to add EXIT at the end):

test.sql

SET ECHO ON

SELECT COUNT(1) FROM dual;

SELECT COUNT(1) FROM (SELECT 1 FROM dual UNION SELECT 2 FROM dual);

EXIT

terminal

sqlplus hr/oracle@orcl @/tmp/test.sql > /tmp/test.log

test.log

SQL> 
SQL> SELECT COUNT(1) FROM dual;

  COUNT(1)
----------
     1

SQL> 
SQL> SELECT COUNT(1) FROM (SELECT 1 FROM dual UNION SELECT 2 FROM dual);

  COUNT(1)
----------
     2

SQL> 
SQL> EXIT

you can do like this in angular 2

in ts file

 export class Component{          
      constructor(){
      }
       printToCart(printSectionId: string){
        let popupWinindow
        let innerContents = document.getElementById(printSectionId).innerHTML;
        popupWinindow = window.open('', '_blank', 'width=600,height=700,scrollbars=no,menubar=no,toolbar=no,location=no,status=no,titlebar=no');
        popupWinindow.document.open();
        popupWinindow.document.write('<html><head><link rel="stylesheet" type="text/css" href="style.css" /></head><body onload="window.print()">' + innerContents + '</html>');
        popupWinindow.document.close();
  }

 }

in html

<div id="printSectionId" >
  <div>
    <h1>AngularJS Print html templates</h1>
    <form novalidate>
      First Name:
      <input type="text"  class="tb8">
      <br>
      <br> Last Name:
      <input type="text"  class="tb8">
      <br>
      <br>
      <button  class="button">Submit</button>
      <button (click)="printToCart('printSectionId')" class="button">Print</button>
    </form>
  </div>
  <div>
    <br/>
   </div>
</div>

pip install -U websocket 

I just use this to fix my problem

Try this one:

System.DateTime.Now.ToString("yyyy/MM/dd HH:mm:ss")

go test -v -timeout 30s <path_to_package> -run ^(TestFuncRegEx)

• The TestFunc must be inside a go test file in that package
• We can provide a regular expression to match a set of test cases or just the exact test case function to run a single test case. For instance -run TestCaseFunc

There is good information on Wikipedia at

Comparison of Issue Tracking Systems

Personally, I'm fond of Trac, which has the capability of integrating with subversion, so when you check in a file, if you say something like...

$ svn ci -m "automatically fix any broken dates in the input.  fixes #87"

....then Trac will automatically add this comment and close bug #87 for you.

Several possibilities : (SwiftUI / Xcode 11)

1 .background(Color.black) //for system colors

2 .background(Color("green")) //for colors you created in Assets.xcassets

3. Otherwise you can do Command+Click on the element and change it from there.

Hope it help :)

This helped me to handle Thread was being aborted exception,

try
{
   //Write HTTP output
    HttpContext.Current.Response.Write(Data);
}  
catch (Exception exc) {}
finally {
   try 
    {
      //stop processing the script and return the current result
      HttpContext.Current.Response.End();
     } 
   catch (Exception ex) {} 
   finally {
        //Sends the response buffer
        HttpContext.Current.Response.Flush();
        // Prevents any other content from being sent to the browser
        HttpContext.Current.Response.SuppressContent = true;
        //Directs the thread to finish, bypassing additional processing
        HttpContext.Current.ApplicationInstance.CompleteRequest();
        //Suspends the current thread
        Thread.Sleep(1);
     }
   }

if you use the following the following code instead of HttpContext.Current.Response.End() , you will get Server cannot append header after HTTP headers have been sent exception.

            HttpContext.Current.Response.Flush();
            HttpContext.Current.Response.SuppressContent = True;
            HttpContext.Current.ApplicationInstance.CompleteRequest();

Hope it helps

fs.readFile takes a call back which calls response.send as you have shown - good. If you simply replace that with fs.readFileSync, you need to be aware it does not take a callback so your callback which calls response.send will never get called and therefore the response will never end and it will timeout.

You need to show your readFileSync code if you're not simply replacing readFile with readFileSync.

Also, just so you're aware, you should never call readFileSync in a node express/webserver since it will tie up the single thread loop while I/O is performed. You want the node loop to process other requests until the I/O completes and your callback handling code can run.

looks like you're better off systeming out to system("grep \"$QUERY\"") since that script won't be particularly high performance either way. Otherwise http://php.net/manual/en/function.file.php shows you how to loop over lines and you can use http://php.net/manual/en/function.strstr.php for finding matches.

This seems to be answered - #include <fstream>.

The message means :-

incomplete type - the class has not been defined with a full class. The compiler has seen statements such as class ifstream; which allow it to understand that a class exists, but does not know how much memory the class takes up.

The forward declaration allows the compiler to make more sense of :-

void BindInput( ifstream & inputChannel ); 

It understands the class exists, and can send pointers and references through code without being able to create the class, see any data within the class, or call any methods of the class.

The has initializer seems a bit extraneous, but is saying that the incomplete object is being created.

try

public void PrintGeneric<T>(T test) where T: ITest
{
    Console.WriteLine("Generic : " + test.@var);
}

as @Ash Burlaczenko has said you cant name a variable after a keyword, if you reallllly want this prefix with @ symbol to escape the keyword

Here is perhaps the simplest explanation of how OAuth2 works for all 4 grant types, i.e., 4 different flows where the app can acquire the access token.

Similarity

All grant type flows have 2 parts:

• Get access token
• Use access token

The 2nd part 'use access token' is the same for all flows

Difference

The 1st part of the flow 'get access token' for each grant type varies.

However, in general the 'get access token' part can be summarized as consisting 5 steps:

1. Pre-register your app (client) with OAuth provider, e.g., Twitter, etc. to get client id/secret
2. Create a social login button with client id & required scopes/permissions on your page so when clicked user gets redirected to OAuth provider to be authenticated
3. OAuth provider request user to grant permission to your app (client)
4. OAuth provider issues code
5. App (client) acquires access token

Here is a side-by-side diagram comparing how each grant type flow is different based on the 5 steps.

This diagram is from https://blog.oauth.io/introduction-oauth2-flow-diagrams/

Each have different levels of implementation difficulty, security, and uses cases. Depending on your needs and situation, you will have to use one of them. Which to use?

Client Credential: If your app is only serving a single user

Resource Owner Password Crendential: This should be used only as last resort as the user has to hand over his credentials to the app, which means the app can do everything the user can

Authorization Code: The best way to get user authorization

Implicit: If you app is mobile or single-page app

There is more explanation of the choice here: https://blog.oauth.io/choose-oauth2-flow-grant-types-for-app/

When you are trying to create a multi-dimensional array all you need to do is add a comma to the declaration like so:

My phone is xiaomi Redmi note 8 with MIUI 11.0.9 . There is no option for create hyperlink : So I use Telegram desktop or Telegram X for create hyperlink because Telegram X supports markdown. Type url and send message (in Telegram X) or there is an alternate way which is the easiest!

Select the text using Xiaomi's Word Editor and click in the three dots on the top right corner of the chat. It is usually used for accessing settings but if you select a text and click there, you can see Telegram's own Formatter!

You can annotate your bean with jaxb annotations.

  @XmlRootElement
  public class MyJaxbBean {
    public String name;
    public int age;

    public MyJaxbBean() {} // JAXB needs this

    public MyJaxbBean(String name, int age) {
      this.name = name;
      this.age = age;
    }
  }

and then your method would look like this:

   @GET @Produces("application/json")
   public MyJaxbBean getMyBean() {
      return new MyJaxbBean("Agamemnon", 32);
   }

There is a chapter in the latest documentation that deals with this:

The only time I've ever used this in practice is with numpy/pandas. For example, with the .isin() dataframe method.

In the docs they show this basic example

>>> df.isin([0, 2])
        num_legs  num_wings
falcon      True       True
dog        False       True

But what if instead you wanted all the rows not in [0, 2]?

>>> ~df.isin([0, 2])
        num_legs  num_wings
falcon     False       False
dog        True        False

I used a variation of Dunni solution above, but that particular code didn't work for me. In particular, when trying to use the Paint object set to have the traits of the view's Paint object, and then calling measureText(), it doesn't return the same value as directly calling the view's Paint object. Perhaps there are some differences in the way my views are set up that make the behavior different.

My solution was to directly use the view's Paint, even though there might be some performance penalties in changing the font size for the view multiple times.

Declare @MonthStart    datetime   = convert(DateTime,'07/01/2016')
Declare @MonthEnd      datetime   = convert(DateTime,'07/31/2016')
Declare @DayCount_int       Int   = 0 
Declare @WhileCount_int     Int   = 0

set @DayCount_int = DATEDIFF(DAY, @MonthStart, @MonthEnd)

BEGIN
   print convert(Varchar(24),DateAdd(day,@WhileCount_int,@MonthStart),101)
   SET @WhileCount_int = @WhileCount_int + 1;
END;

Casting to an int truncates the value. Adding 0.5 causes it to do proper rounding.

int y = (int)(x + 0.5);

Variables in single-quotes are not evaluated. Use double quotes:

ssh [email protected] "~/tools/run_pvt.pl $BUILD_NUMBER"

The shell will expand variables in double-quotes, but not in single-quotes. This will change into your desired string before being passed to the ssh command.

Simply use the base transpose function t, wrapped with as.data.frame:

final_df <- as.data.frame(t(starting_df))
final_df
     A    B    C    D
a    1    2    3    4
b 0.02 0.04 0.06 0.08
c Aaaa Bbbb Cccc Dddd

Above updated. As docendo discimus pointed out, t returns a matrix. As Mark suggested wrapping it with as.data.frame gets back a data frame instead of a matrix. Thanks!

Have you seen this question and its answer?

You can set a globally valid value for you app like this:

app.value('key', 'value');

and then use it in your services. You could move this code to a config.js file and execute it on page load or another convenient moment.

You don't add or link directly against a DLL, you link against the LIB produced by the DLL.

A LIB provides symbols and other necessary data to either include a library in your code (static linking) or refer to the DLL (dynamic linking).

To link against a LIB, you need to add it to the project Properties -> Linker -> Input -> Additional Dependencies list. All LIB files here will be used in linking. You can also use a pragma like so:

#pragma comment(lib, "dll.lib")

With static linking, the code is included in your executable and there are no runtime dependencies. Dynamic linking requires a DLL with matching name and symbols be available within the search path (which is not just the path or system directory).

To extend your max_execution_time you can use either ini_set or set_time_limit.

// Set maximum execution time to 10 seconds this way
ini_set('max_execution_time', 10);
// or this way
set_time_limit(10);

!! But be aware that, both functions restarts also counting of time script has already taken to execute

sleep(2);
ini_set('max_execution_time', 5);

register_shutdown_function(function(){
    var_dump(microtime(true) - $_SERVER['REQUEST_TIME_FLOAT']);
});

for(;;);

//
// var_dump outputs float(7.1981489658356)
//

so if you want to set exact maximum amount of time script can run, your command must be very first.

Differences between those two functions are

• set_time_limit does not return info whether it was successful but it will throw a warning on error.
• ini_set returns old value on success, or false on failure without any warning/error

Explicitly filling in the ContentDisposition fields did the trick.

if (attachmentFilename != null)
{
    Attachment attachment = new Attachment(attachmentFilename, MediaTypeNames.Application.Octet);
    ContentDisposition disposition = attachment.ContentDisposition;
    disposition.CreationDate = File.GetCreationTime(attachmentFilename);
    disposition.ModificationDate = File.GetLastWriteTime(attachmentFilename);
    disposition.ReadDate = File.GetLastAccessTime(attachmentFilename);
    disposition.FileName = Path.GetFileName(attachmentFilename);
    disposition.Size = new FileInfo(attachmentFilename).Length;
    disposition.DispositionType = DispositionTypeNames.Attachment;
    message.Attachments.Add(attachment);                
}

The simplest way to do that is by opening the certificate store you want and then using X509Certificate2UI.

var store = new X509Store(StoreName.My, StoreLocation.LocalMachine);
store.Open(OpenFlags.ReadOnly);

    store.Certificates, 
    "Title",

After installing Free BitDefender AntiVirus the services related to the AntiVirus used about 80 MB of my computer's Memory. I also noticed that after installing BitDefender the service related to windows Presentation Font Cache was also installed: "WPFFontCache_v0300.exe". I disabled the service from stating automatically and now BitDefender Free AntiVirus use only 15-20 MB (!!!) of my computer's Memory! As far as I concern, this service affected negatively the memory usage of my PC inother services. I recommend you to disable it.

If you go into Configure under Home there is a "Help" note on how to:

Home directory /var/lib/jenkins Help for feature: Home directory

By default, Jenkins stores all of its data in this directory on the file system.

There are a few ways to change the Jenkins home directory:

Edit the JENKINS_HOME variable in your Jenkins configuration file (e.g. /etc/sysconfig/jenkins on Red Hat Linux).
Use your web container's admin tool to set the JENKINS_HOME environment variable.
Set the environment variable JENKINS_HOME before launching your web container, or before launching Jenkins directly from the WAR file.
Set the JENKINS_HOME Java system property when launching your web container, or when launching Jenkins directly from the WAR file.
Modify web.xml in jenkins.war (or its expanded image in your web container). This is not recommended. 

This value cannot be changed while Jenkins is running. It is shown here to help you ensure that your configuration is taking effect.

An optional is to use pyvirtualdisplay like this:

from pyvirtualdisplay import Display

display = Display(visible=0, size=[800, 600])
display.start()

#do selenium job here

display.close()

A shorter version is:

with Display() as display:
    # selenium job here

This is generally a python encapsulate of xvfb, and more convinient somehow.

By the way, although PhantomJS is a headless browser and no window will be open if you use it, it seems that PhantomJS still needs a gui environment to work.

I got Error Code -6 when I use PhantomJS() instead of Firefox() in headless mode (putty-connected console). However everything is ok in desktop environment.

Well, weeks ago I made a very similiar question (Get CDN url from uploaded file via Storage): I wanted the CDN url to show the image in my view (as you are requiring ).

However, after review the package API I confirmed that there is no way do this task. So, my solution was avoid using flysystem. In my case, I needed to play with RackSpace. So, finally decide to create my use package and make my own storage package using The PHP SDK for OpenStack.

By this way, you have full access for functions that you need like getPublicUrl() in order to get the public URL from a cdn container:

/** @var DataObject $file */
$file = \OpenCloud::container('cdn')->getObject('screenshots/1.jpg');

// $url:  https://d224d291-8316ade.ssl.cf1.rackcdn.com/screenshots/1.jpg
$url = (string) $file->getPublicUrl(UrlType::SSL);

In conclusion, if need to take storage service to another level, then flysystem is not enough. For local purposes, you can try @nXu's solution

From a new react/redux adopter migrating from (a few years of) ExtJS in mid-2018:

After sliding backward down the redux learning curve I had the same question and thought pure flux would be simpler like OP.

I soon saw the benefits of redux over flux as noted in the answers above, and was working it into my first app.

While getting a grip on the boiler plate again, I tried out a few of the other state management libs, the best I found was rematch.

It was much more intuitive then vanilla redux, it cuts out 90% of the boilerplate and cut out 75% of the time I was spending on redux (something I think a library should be doing), I was able to get a couple enterprise apps going right away.

It also runs with the same redux tooling. This is a good article that covers some of the benefits.

So for anyone else who arrived to this SO post searching "simpler redux", I recommend trying it out as a simple alternative to redux with all the benefits and 1/4 of the boilerplate.

Try

public bool IsDivisible(int x, int n)
{
   return (x % n) == 0;
}

The modulus operator % returns the remainder after dividing x by n which will always be 0 if x is divisible by n.

For more information, see the % operator on MSDN.

Because "append" intuitively means "add at the end of the list". If it was called "push", then it would be unclear whether we're adding stuff at the tail or at head of the list.

Indeed you are on the right track. You should use another thread, and you have identified the best ways to do that. The rest is just updating the progress bar. In case you don't want to use BackgroundWorker like others have suggested, there is one trick to keep in mind. The trick is that you cannot update the progress bar from the worker thread because UI can be only manipulated from the UI thread. So you use the Invoke method. It goes something like this (fix the syntax errors yourself, I'm just writing a quick example):

class MyForm: Form
{
    private void delegate UpdateDelegate(int Progress);

    private void UpdateProgress(int Progress)
    {
        if ( this.InvokeRequired )
            this.Invoke((UpdateDelegate)UpdateProgress, Progress);
        else
            this.MyProgressBar.Progress = Progress;
    }
}

The InvokeRequired property will return true on every thread except the one that owns the form. The Invoke method will call the method on the UI thread, and will block until it completes. If you don't want to block, you can call BeginInvoke instead.

1.) Storage of database passwords Use some kind of hash with a salt and then alter the hash, obfuscate it, for example add a distinct value for each byte. That way your passwords a super secured against dictionary attacks and rainbow tables.

2.) To check if the password matches, create your hash for the password the user put in. Then perform a query against the database for the username and just check if the two password hashes are identical. If they are, give the user an authentication token.

The query should then look like this:

select hashedPassword from users where username=?

Then compare the password to the input.

I use the following extension methods. They have optimized overloads for when one stream is a MemoryStream.

    public static void CopyTo(this Stream src, Stream dest)
    {
        int size = (src.CanSeek) ? Math.Min((int)(src.Length - src.Position), 0x2000) : 0x2000;
        byte[] buffer = new byte[size];
        int n;
        do
        {
            n = src.Read(buffer, 0, buffer.Length);
            dest.Write(buffer, 0, n);
        } while (n != 0);           
    }

    public static void CopyTo(this MemoryStream src, Stream dest)
    {
        dest.Write(src.GetBuffer(), (int)src.Position, (int)(src.Length - src.Position));
    }

    public static void CopyTo(this Stream src, MemoryStream dest)
    {
        if (src.CanSeek)
        {
            int pos = (int)dest.Position;
            int length = (int)(src.Length - src.Position) + pos;
            dest.SetLength(length); 

            while(pos < length)                
                pos += src.Read(dest.GetBuffer(), pos, length - pos);
        }
        else
            src.CopyTo((Stream)dest);
    }

1. Go to Info.plist file
2. Hover on one of those lines and a (+) and (-) button will show up.
3. Click the plus button to add new key Type in start with capital V and automatically the first choice will be View controller-based status bar appearance.
4. Add that as the KEY.
5. Set the VALUE to "NO"
6. Go to you AppDelegate.swift

7. Add the code, inside the method

   func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject:AnyObject]?) -> Bool {
       application.statusBarHidden = true
       return true
   }
   

DONE! Run your app and no more status bar!

When you include Underscore, it attaches itself to the window object, and so is available globally.

So you can use it from Angular code as-is.

You can also wrap it up in a service or a factory, if you'd like it to be injected:

var underscore = angular.module('underscore', []);
underscore.factory('_', ['$window', function($window) {
  return $window._; // assumes underscore has already been loaded on the page
}]);

And then you can ask for the _ in your app's module:

// Declare it as a dependency of your module
var app = angular.module('app', ['underscore']);

// And then inject it where you need it
app.controller('Ctrl', function($scope, _) {
  // do stuff
});

Mac users can avoid auto formatting by reading directly from the pasteboard with:

class of my button is "input-addon btn btn-default fileinput-exists"

below code helped me

document.querySelector('.input-addon.btn.btn-default.fileinput-exists').click();

but I want to click second button, I have two buttons in my screen so I used querySelectorAll

var elem = document.querySelectorAll('.input-addon.btn.btn-default.fileinput-exists');
                elem[1].click();

here elem[1] is the second button object that I want to click.

Try adding below CSS

textarea
{
    overflow-y:scroll;
}

since 1.5.0 u can use the 'inline' keyword.

Example: @import (inline) "not-less-compatible.css";

You will use this when a CSS file may not be Less compatible; this is because although Less supports most known standards CSS, it does not support comments in some places and does not support all known CSS hacks without modifying the CSS. So you can use this to include the file in the output so that all CSS will be in one file.

ECUs (EC2 Computer Units) are a rough measure of processor performance that was introduced by Amazon to let you compare their EC2 instances ("servers").

CPU performance is of course a multi-dimensional measure, so putting a single number on it (like "5 ECU") can only be a rough approximation. If you want to know more exactly how well a processor performs for a task you have in mind, you should choose a benchmark that is similar to your task.

In early 2014, there was a nice benchmarking site comparing cloud hosting offers by tens of different benchmarks, over at CloudHarmony benchmarks. However, this seems gone now (and archive.org can't help as it was a web application). Only an introductory blog post is still available.

Also useful: ec2instances.info, which at least aggregates the ECU information of different EC2 instances for comparison. (Add column "Compute Units (ECU)" to make it work.)

I only use MicrosoftAdvertising.Mobile and Microsoft.Advertising.Mobile.UI and I am served ads. The SDK should only add the DLLs not reference itself.

Note: You need to explicitly set width and height Make sure the phone dialer, and web browser capabilities are enabled

Followup note: Make sure that after you've removed the SDK DLL, that the xmlns references are not still pointing to it. The best route to take here is

1. Remove the XAML for the ad
2. Remove the xmlns declaration (usually at the top of the page, but sometimes will be declared in the ad itself)
3. Remove the bad DLL (the one ending in .SDK )
4. Do a Clean and then Build (clean out anything remaining from the DLL)
5. Add the xmlns reference (actual reference is below)
6. Add the ad to the page (example below)

Here is the xmlns reference:

xmlns:AdNamepace="clr-namespace:Microsoft.Advertising.Mobile.UI;assembly=Microsoft.Advertising.Mobile.UI" 

Then the ad itself:

<AdNamespace:AdControl x:Name="myAd" Height="80" Width="480"                    AdUnitId="yourAdUnitIdHere" ApplicationId="yourIdHere"/> 

I think a better way to solve this would be to use the datetime callable:

from datetime import datetime

date = models.DateField(default=datetime.now)

Note that no parenthesis were used. If you used parenthesis you would invoke the now() function just once (when the model is created). Instead, you pass the callable as an argument, thus being invoked everytime an instance of the model is created.

Credit to Django Musings. I've used it and works fine.

Since hashes aren't inherently ordered, there isn't a notion of appending. Ruby hashes since 1.9 maintain insertion order, however. Here are the ways to add new key/value pairs.

The simplest solution is

h[:key] = "bar"

If you want a method, use store:

h.store(:key, "bar")

If you really, really want to use a "shovel" operator (<<), it is actually appending to the value of the hash as an array, and you must specify the key:

h[:key] << "bar"

The above only works when the key exists. To append a new key, you have to initialize the hash with a default value, which you can do like this:

h = Hash.new {|h, k| h[k] = ''}
h[:key] << "bar"

You may be tempted to monkey patch Hash to include a shovel operator that works in the way you've written:

class Hash
  def <<(k,v)
    self.store(k,v)
  end
end

However, this doesn't inherit the "syntactic sugar" applied to the shovel operator in other contexts:

h << :key, "bar" #doesn't work
h.<< :key, "bar" #works

What about constructing the element using jQuery? e.g.

$("<div></div>")

creates a new div element, ready to be added to the page. Can be shortened further to

$("<div>")

then you can chain on commands that you need, set up event handlers and append it to the DOM. For example

$('<div id="myid">Div Content</div>')
    .bind('click', function(e) { /* event handler here */ })
    .appendTo('#myOtherDiv');

I solved this problem occurring on OS X with Django both 1.5 and 1.6 by deactivating all active sessions to virtualenv and starting it again.

Request.GetOwinContext().Authentication.User.Claims

However it is better to add the claims inside the "GenerateUserIdentityAsync" method, especially if regenerateIdentity in the Startup.Auth.cs is enabled.

All things being equal, I'd expect most people to use whatever is most conveniently available, and that tends to be qsort(3). Other than that quicksort is known to be very fast on arrays, just like mergesort is the common choice for lists.

What I'm wondering is why it's so rare to see radix or bucket sort. They're O(n), at least on linked lists and all it takes is some method of converting the key to an ordinal number. (strings and floats work just fine.)

I'm thinking the reason has to do with how computer science is taught. I even had to demonstrate to my lecturer in Algorithm analysis that it was indeed possible to sort faster than O(n log(n)). (He had the proof that you can't comparison sort faster than O(n log(n)), which is true.)

In other news, floats can be sorted as integers, but you have to turn the negative numbers around afterwards.

Edit: Actually, here's an even more vicious way to sort floats-as-integers: http://www.stereopsis.com/radix.html. Note that the bit-flipping trick can be used regardless of what sorting algorithm you actually use...

You can set the ReadOnly property to true.

Quoth the link:

When this property is set to true, the contents of the control cannot be changed by the user at runtime. With this property set to true, you can still set the value of the Text property in code. You can use this feature instead of disabling the control with the Enabled property to allow the contents to be copied and ToolTips to be shown.

    while ((inputLine = bufferedReader.readLine()) != null)
    {
        stringBuilder.append(inputLine);
        stringBuilder.append(System.lineSeparator());
    }

    bufferedReader.close();
    return stringBuilder.toString().trim();
}

Pure-CSS solution with calc(), CSS units and math

This is precisely not what OP asks, but may make someone's day. This answer is not spoon-feedingly easy and needs some researching on the developer end.

I came finally to get a pure-CSS solution for this using calc() with different units. You will need some basic mathematical understanding of formulas to work out your expression for calc().

When I worked this out, I had to get a full-page-width responsive header with some padding few parents up in DOM. I'll use my values here, replace them with your own.

To mathematics

You will need:

• Nicely adjusted ratio in some viewport. I used 320 pixels, thus I got 24 pixels high and 224 pixels wide, so the ratio is 9.333... or 28 / 3
• The container width, I had padding: 3em and full width so this got to 100wv - 2 * 3em

X is the width of container, so replace it with your own expression or adjust the value to get full-page text. R is the ratio you will have. You can get it by adjusting the values in some viewport, inspecting element width and height and replacing them with your own values. Also, it is width / heigth ;)

x = 100vw - 2 * 3em = 100vw - 6em
r = 224px/24px = 9.333... = 28 / 3

y = x / r
  = (100vw - 6em) / (28 / 3)
  = (100vw - 6em) * 3 / 28
  = (300vw - 18em) / 28
  = (75vw - 4.5rem) / 7

And bang! It worked! I wrote

font-size: calc((75vw - 4.5rem) / 7)

to my header and it adjusted nicely in every viewport.

But how does it work?

We need some constants up here. 100vw means the full width of viewport, and my goal was to establish full-width header with some padding.

The ratio. Getting a width and height in one viewport got me a ratio to play with, and with ratio I know what the height should be in other viewport width. Calculating them with hand would take plenty of time and at least take lots of bandwidth, so it's not a good answer.

Conclusion

I wonder why no-one has figured this out and some people are even telling that this would be impossible to tinker with CSS. I don't like to use JavaScript in adjusting elements, so I don't accept JavaScript (and forget about jQuery) answers without digging more. All in all, it's good that this got figured out and this is one step to pure-CSS implementations in website design.

I apologize of any unusual convention in my text, I'm not native speaker in English and am also quite new to writing Stack Overflow answers.

It should also be noted that we have evil scrollbars in some browsers. For example, when using Firefox I noticed that 100vw means the full width of viewport, extending under scrollbar (where content cannot expand!), so the fullwidth text has to be margined carefully and preferably get tested with many browsers and devices.

GLHF!

You are just Compare zeroth element with rest of the elements so it will print the value last largest value which it will contain, in you case, same problem is happening. To compare each and every elements we have to swap the values like:

double max = decMax[0];
    for (int counter = 1; counter < decMax.length; counter++){
        if(max<decMax[i]){
            max=decMax[i]; //swapping
            decMax[i]=decMax[0];
        }
    }
    System.out.println("The max value is "+ max);

Data Soruce -> Advanced -> Look at the column that goes in error -> change OutputColumnWidth to 200 and try again.

I was looking for a pure CSS solution using img tags (not the background image way).

I found this brilliant way to achieve the goal on crop thumbnails with css:

.thumbnail {
  position: relative;
  width: 200px;
  height: 200px;
  overflow: hidden;
}
.thumbnail img {
  position: absolute;
  left: 50%;
  top: 50%;
  height: 100%;
  width: auto;
  -webkit-transform: translate(-50%,-50%);
      -ms-transform: translate(-50%,-50%);
          transform: translate(-50%,-50%);
}
.thumbnail img.portrait {
  width: 100%;
  height: auto;
}

It is similar to @Nathan Redblur's answer but it allows for portrait images, too.

Works like a charm for me. The only thing you need to know about the image is whether it is portrait or landscape in order to set the .portrait class so I had to use a bit of Javascript for this part.

You can use it for do something after reload data:

[UIView animateWithDuration:0 animations:^{
    [self.contentTableView reloadData];
} completion:^(BOOL finished) {
    _isUnderwritingUpdate = NO;
}];

After some googling I found this:

curl -c cookie.txt -d "LoginName=someuser" -d "password=somepass" https://oursite/a
curl -b cookie.txt https://oursite/b

No idea if it works, but it might lead you in the right direction.

ls -sh video.mp4 | sed s/video.mp4//g

output, 5.6M

Consider the limitations of the different Load* methods. From the MSDN docs...

LoadFile does not load files into the LoadFrom context, and does not resolve dependencies using the load path, as the LoadFrom method does.

More information on Load Contexts can be found in the LoadFrom docs.

Python is very sensitive to indentation, with the code below I got the same error:

    except IntegrityError as e:
        if 'unique constraint' in e.args:
            return render(request, "calender.html")

The correct indentation is:

    except IntegrityError as e:
        if 'unique constraint' in e.args:
        return render(request, "calender.html")

That should work via HTTPRewriteModule.

Example rewrite from www.example.com to example.com:

server {    
    server_name www.example.com;    
    rewrite ^ http://example.com$request_uri? permanent; 
}

The new django.urls.path() function allows a simpler, more readable URL routing syntax. For example, this example from previous Django releases:

url(r'^articles/(?P<year>[0-9]{4})/$', views.year_archive)

could be written as:

path('articles/<int:year>/', views.year_archive)

The django.conf.urls.url() function from previous versions is now available as django.urls.re_path(). The old location remains for backwards compatibility, without an imminent deprecation. The old django.conf.urls.include() function is now importable from django.urls so you can use:

from django.urls import include, path, re_path

in the URLconfs. For further reading django doc

According to your CSS file path, I will suppose it is at the same directory with your HTML page, you have to change the url as follows:

body { background: url(img/debut_dark.png) repeat 0 0; }

The problem is that if you try to write a <table> or a <tr> or <td> tag using JS every time you insert a new tag the browser will try to close it as it will think that there is an error on the code.

Instead of writing your table line by line, concatenate your table into a variable and insert it once created:

<script language="javascript" type="text/javascript">
<!--

var myArray    = new Array();
    myArray[0] = 1;
    myArray[1] = 2.218;
    myArray[2] = 33;
    myArray[3] = 114.94;
    myArray[4] = 5;
    myArray[5] = 33;
    myArray[6] = 114.980;
    myArray[7] = 5;

    var myTable= "<table><tr><td style='width: 100px; color: red;'>Col Head 1</td>";
    myTable+= "<td style='width: 100px; color: red; text-align: right;'>Col Head 2</td>";
    myTable+="<td style='width: 100px; color: red; text-align: right;'>Col Head 3</td></tr>";

    myTable+="<tr><td style='width: 100px;                   '>---------------</td>";
    myTable+="<td     style='width: 100px; text-align: right;'>---------------</td>";
    myTable+="<td     style='width: 100px; text-align: right;'>---------------</td></tr>";

  for (var i=0; i<8; i++) {
    myTable+="<tr><td style='width: 100px;'>Number " + i + " is:</td>";
    myArray[i] = myArray[i].toFixed(3);
    myTable+="<td style='width: 100px; text-align: right;'>" + myArray[i] + "</td>";
    myTable+="<td style='width: 100px; text-align: right;'>" + myArray[i] + "</td></tr>";
  }  
   myTable+="</table>";

 document.write( myTable);

//-->
</script> 

If your code is in an external JS file, in HTML create an element with an ID where you want your table to appear:

<div id="tablePrint"> </div>

And in JS instead of document.write(myTable) use the following code:

document.getElementById('tablePrint').innerHTML = myTable;

Solution without Mocking class, Java9+ and Spring only.

FileItem fileItem = new DiskFileItemFactory().createItem("file",
    Files.probeContentType(file.toPath()), false, file.getName());

try (InputStream in = new FileInputStream(file); OutputStream out = fileItem.getOutputStream()) {
    in.transferTo(out);
} catch (Exception e) {
    throw new IllegalArgumentException("Invalid file: " + e, e);
}

CommonsMultipartFile multipartFile = new CommonsMultipartFile(fileItem);

I have modified a bit the code above. for me 0 !== false and null !== undefined. If you do not need such strict check remove one "=" sign in "this[p] !== x[p]" inside the code.

Object.prototype.equals = function(x){
    for (var p in this) {
        if(typeof(this[p]) !== typeof(x[p])) return false;
        if((this[p]===null) !== (x[p]===null)) return false;
        switch (typeof(this[p])) {
            case 'undefined':
                if (typeof(x[p]) != 'undefined') return false;
                break;
            case 'object':
                if(this[p]!==null && x[p]!==null && (this[p].constructor.toString() !== x[p].constructor.toString() || !this[p].equals(x[p]))) return false;
                break;
            case 'function':
                if (p != 'equals' && this[p].toString() != x[p].toString()) return false;
                break;
            default:
                if (this[p] !== x[p]) return false;
        }
    }
    return true;
}

Then I have tested it with next objects:

var a = {a: 'text', b:[0,1]};
var b = {a: 'text', b:[0,1]};
var c = {a: 'text', b: 0};
var d = {a: 'text', b: false};
var e = {a: 'text', b:[1,0]};
var f = {a: 'text', b:[1,0], f: function(){ this.f = this.b; }};
var g = {a: 'text', b:[1,0], f: function(){ this.f = this.b; }};
var h = {a: 'text', b:[1,0], f: function(){ this.a = this.b; }};
var i = {
    a: 'text',
    c: {
        b: [1, 0],
        f: function(){
            this.a = this.b;
        }
    }
};
var j = {
    a: 'text',
    c: {
        b: [1, 0],
        f: function(){
            this.a = this.b;
        }
    }
};
var k = {a: 'text', b: null};
var l = {a: 'text', b: undefined};

a==b expected true; returned true

a==c expected false; returned false

c==d expected false; returned false

a==e expected false; returned false

f==g expected true; returned true

h==g expected false; returned false

i==j expected true; returned true

d==k expected false; returned false

k==l expected false; returned false

In the current version of Sublime Text 2 (Build: 2139), you can set the syntax for all files of a certain file extension using an option in the menu bar. Open a file with the extension you want to set a default for and navigate through the following menus: View -> Syntax -> Open all with current extension as... ->[your syntax choice].

Updated 2012-06-28: Recent builds of Sublime Text 2 (at least since Build 2181) have allowed the syntax to be set by clicking the current syntax type in the lower right corner of the window. This will open the syntax selection menu with the option to Open all with current extension as... at the top of the menu.

Updated 2016-04-19: As of now, this also works for Sublime Text 3.

Putting it simply:

As the name suggests, it's the context of current state of the application/object. It lets newly-created objects understand what has been going on. Typically you call it to get information regarding another part of your program (activity and package/application).

You can get the context by invoking getApplicationContext(), getContext(), getBaseContext() or this (when in a class that extends from Context, such as the Application, Activity, Service and IntentService classes).

Typical uses of context:

• Creating new objects: Creating new views, adapters, listeners:

  TextView tv = new TextView(getContext());
  ListAdapter adapter = new SimpleCursorAdapter(getApplicationContext(), ...);
  

• Accessing standard common resources: Services like LAYOUT_INFLATER_SERVICE, SharedPreferences:

  context.getSystemService(LAYOUT_INFLATER_SERVICE)
  getApplicationContext().getSharedPreferences(*name*, *mode*);
  

• Accessing components implicitly: Regarding content providers, broadcasts, intent

  getApplicationContext().getContentResolver().query(uri, ...);
  

You can use the following-

public void mop(Integer x) {
  // Define default values
        x = x == null ? 200 : x;
}

You can do it with jQuery.

I have my video and controls in their own <div> like this:

<div id="videoPlayer" style="width:520px; -webkit-border-radius:10px; height:420px; background-color:white; position:relative; float:left; left:25px; top:55px;" align="center">

    <video controls width="500" height="400" style="background-color:black; margin-top:10px; -webkit-border-radius:10px;">
         <source src="videos/gin.mp4" type="video/mp4" />
    </video>

    <script>  
        video.removeAttribute('controls');  
    </script> 

    <div id="vidControls" style="position:relative; width:100%; height:50px; background-color:white; -webkit-border-bottom-left-radius:10px; -webkit-border-bottom-right-radius:10px; padding-top:10px; padding-bottom:10px;">

         <table width="100%" height="100%" border="0">

             <tr>
                 <td width="100%" align="center" valign="middle" colspan="4"><input class="vidPos" type="range" value="0" step="0.1" style="width:500px;" /></td>
             </tr>

             <tr>
                 <td width="100%" align="center" valign="middle"><a href="javascript:;" class="playVid">Play</a></td>
                 <td width="100%" align="center" valign="middle"><a href="javascript:;" class="vol">Vol</a></td>
                 <td width="100%" align="left" valign="middle"><p class="timer"><strong>0:00</strong> / 0:00</p></td>
                 <td width="100%" align="center" valign="middle"><a href="javascript:;" class="fullScreen">Full</a></td>
              </tr>

            </table>

         </div>

      </div>

And then my jQuery for the .fullscreen class is:

var fullscreen = 0;

$(".fullscreen").click(function(){
  if(fullscreen == 0){
    fullscreen = 1;
    $("video").appendTo('body');
    $("#vidControls").appendTo('body');
    $("video").css('position', 'absolute').css('width', '100%').css('height', '90%').css('margin', 0).css('margin-top', '5%').css('top', '0').css('left', '0').css('float', 'left').css('z-index', 600);
    $("#vidControls").css('position', 'absolute').css('bottom', '5%').css('width', '90%').css('backgroundColor', 'rgba(150, 150, 150, 0.5)').css('float', 'none').css('left', '5%').css('z-index', 700).css('-webkit-border-radius', '10px');

}
else
    {

        fullscreen = 0;

        $("video").appendTo('#videoPlayer');
        $("#vidControls").appendTo('#videoPlayer');

        //change <video> css back to normal

        //change "#vidControls" css back to normal

    }

});

It needs a little cleaning up as I'm still working on it but that should work for most browsers as far as I can see.

Hope it helps!

Nope. The reason ActiveX can do it is because ActiveX is a little application that runs on the client's machine.

I would imagine access to such information via JavaScript would be a security vulnerability.

SELECT @var = col1,
       @var2 = col2
FROM   Table

Here is some interesting information about SET / SELECT

• SET is the ANSI standard for variable assignment, SELECT is not.
• SET can only assign one variable at a time, SELECT can make multiple assignments at once.
• If assigning from a query, SET can only assign a scalar value. If the query returns multiple values/rows then SET will raise an error. SELECT will assign one of the values to the variable and hide the fact that multiple values were returned (so you'd likely never know why something was going wrong elsewhere - have fun troubleshooting that one)
• When assigning from a query if there is no value returned then SET will assign NULL, where SELECT will not make the assignment at all (so the variable will not be changed from it's previous value)
• As far as speed differences - there are no direct differences between SET and SELECT. However SELECT's ability to make multiple assignments in one shot does give it a slight speed advantage over SET.

Kinda late.But it just takes a bit of math.

.content {
  margin-top: 50px;
  background: #777;
  padding: 30px;
  padding-bottom: 0;
  font-size: 11px;
  border: 1px dotted #222;
}

.bottom-content {
  background: #999;
  width: 100%; /* you need this for it to work */
  margin-left: -30px; /* will touch very left side */
  padding-right: 60px; /* will touch very right side */
}

<div class='content'>

  <p>A paragraph</p>
  <p>Another paragraph.</p>
  <p>No more content</p>


  <div class='bottom-content'>
      I want this div to ignore padding.
  </div>

I don't have Windows so I didn't test this in IE.

fiddle: fiddle example..

You can do this in your code:

final ListView lv = (ListView) convertView.findViewById(R.id.list_view);

for (int i = 0; i < lv.getChildCount(); i++) {
    ((TextView)lv.getChildAt(i)).setTextColor(getResources().getColor(R.color.black));
}

Try this:

UPDATE barang
SET ID FROM(SELECT tblkatalog.tblkatalog_id FROM tblkatalog 
WHERE tblkatalog.tblkatalog_nomor = barang.NO_CAT) WHERE barang.NO_CAT <>'';

Though this question has been answered. I would like to put something extra, i.e. if there is a file exist with the directory name that you are trying to create than it should prompt an error. For future visitors.

public static void makeDir()
{
    File directory = new File(" dirname ");
    if (directory.exists() && directory.isFile())
    {
        System.out.println("The dir with name could not be" +
        " created as it is a normal file");
    }
    else
    {
        try
        {
            if (!directory.exists())
            {
                directory.mkdir();
            }
            String username = System.getProperty("user.name");
            String filename = " path/" + username + ".txt"; //extension if you need one

        }
        catch (IOException e)
        {
            System.out.println("prompt for error");
        }
    }
}

nl2br() as you have it should work fine:

$description = nl2br($description);

It's more likely that the unclosed ' on the first line of your example code is causing your issue. Remove the ' after $description...

...$description');

Doesn't nth-child return siblings rather than children?

var $selFirst = $(".second:nth-child(1)");

will return the first element with the class '.second'.

var $selFirst = $(".selector:nth-child(1)");

should give you the first sibling of class '.selector'

get the latest version information from:

https://mvnrepository.com/artifact/org.apache.maven.plugins/maven-compiler-plugin

click on the latest version (or the one you'd like to use) and you'll see the the dependency info (as of 2019-05 it's 3.8.1):

<!-- https://mvnrepository.com/artifact/org.apache.maven.plugins/maven-compiler-plugin -->
<dependency>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-compiler-plugin</artifactId>
  <version>3.8.1</version>
</dependency>

you might want to use the version tag and the comment for your plugin tag.

<!-- https://mvnrepository.com/artifact/org.apache.maven.plugins/maven-compiler-plugin -->

if you like you can modify your pom to have the version information in the properties tag as outlined in another answer.

Here is how I do this. I create a table with a thead and tbody tags. And then add a click event to the tbody element by id.

<script>
    document.getElementById("mytbody").click = clickfunc;
    function clickfunc(e) {
        // to find what td element has the data you are looking for
        var tdele = e.target.parentNode.children[x].innerHTML;
        // to find the row
        var trele = e.target.parentNode;
    }
</script>
<table>
    <thead>
        <tr>
            <th>Header 1</th>
            <th>Header 2</th>
        </tr>
    </thead>
    <tbody id="mytbody">
        <tr><td>Data Row</td><td>1</td></tr>
        <tr><td>Data Row</td><td>2</td></tr>
        <tr><td>Data Row</td><td>3</td></tr>
    </tbody>
</table>

netstat -ln | awk '/^(tcp|udp)/ { split($4, a, /:/); print $1, a[2]}' | sort -u

gives you the active tcp/udp ports. Then you can use the ports with fuser -n tcp or fuser -n udp, as root, and supposing that fuser is GNU fuser or has similar options.

If you need more help, let me know.

You are off slightly on a few things here, so hopefully the following helps.

Firstly, you don't need to select ranges to access their properties, you can just specify their address etc. Secondly, unless you are manipulating the values within the range, you don't actually need to set them to a variant. If you do want to manipulate the values, you can leave out the bounds of the array as it will be set when you define the range.

It's also good practice to use Option Explicit at the top of your modules to force variable declaration.

The following will do what you are after:

Sub ARRAYER()
    Dim Number_of_Sims As Integer, i As Integer

    Number_of_Sims = 10

    For i = 1 To Number_of_Sims
       'Do your calculation here to update C4 to G4
       Range(Cells(4 + i, "C"), Cells(4 + i, "G")).Value = Range("C4:G4").Value
    Next
End Sub

If you do want to manipulate the values within the array then do this:

Sub ARRAYER()
    Dim Number_of_Sims As Integer, i As Integer
    Dim anARRAY as Variant

    Number_of_Sims = 10

    For i = 1 To Number_of_Sims
       'Do your calculation here to update C4 to G4
       anARRAY= Range("C4:G4").Value

       'You can loop through the array and manipulate it here

       Range(Cells(4 + i, "C"), Cells(4 + i, "G")).Value = anARRAY
    Next
End Sub

Array(100).fill().map((_,i)=> console.log(i) );

This version satisifies the OP's requirement for immutability. Also consider using reduce instead of map depending on your use case.

This is also an option if you don't mind a little mutation in your prototype.

Number.prototype.times = function(f) {
   return Array(this.valueOf()).fill().map((_,i)=>f(i));
};

Now we can do this

((3).times(i=>console.log(i)));

+1 to arcseldon for the .fill suggestion.

Although this is an old post, I thought that a simple function can make the code more readable and keeps with jQuery chaining code-style:

String.prototype.toNum = function(){
    return parseInt(this, 10);
}

can be used with jQuery:

var padding_top = $('#some_div').css('padding-top'); //string: "10px"
var padding_top = $('#some_div').css('padding-top').toNum(); //number: 10`

or with any String object:

"123".toNum(); //123 (number)`

This not only works with cmake, but also with ./configure and make:

./configure CC=/usr/local/bin/gcc CXX=/usr/local/bin/g++

Which is resulting in:

checking for gcc... /usr/local/bin/gcc
checking whether the C compiler works... yes

DDL stands for Data Definition Language. DDL is used for defining structure of the table such as create a table or adding a column to table and even drop and truncate table. DML stands for Data Manipulation Language. As the name suggest DML used for manipulating the data of table. There are some commands in DML such as insert and delete.

This can happen on foreachs when using:

foreach( $array as $key = $value )

instead of

foreach( $array as $key => $value )

I needed the same thing, and although AFAIK this cannot be done programmatically, it worked for me.

I just went to Start --> Uninstall a program, and scrolled down until I found the VC++ redistributable, which includes a version number. Googling the version number, told me it belongs to VS2012 SP1.

Okay, I'm not going to tell you a magical way of doing it because there isn't. If you have an action attribute set for a form element, it will redirect.

If you don't want it to redirect simply don't set any action and set onsubmit="someFunction();"

In your someFunction() you do whatever you want, (with AJAX or not) and in the ending, you add return false; to tell the browser not to submit the form...

Simple version for Python 2.7+

my_ordered_dict = json.loads(json_str, object_pairs_hook=collections.OrderedDict)

Or for Python 2.4 to 2.6

import simplejson as json
import ordereddict

my_ordered_dict = json.loads(json_str, object_pairs_hook=ordereddict.OrderedDict)

Wrap the code within $(document).ready(function(){...........}); handler , also remove the ; after if

$(document).ready(function(){
    $('#purpose').on('change', function() {
      if ( this.value == '1')
      //.....................^.......
      {
        $("#business").show();
      }
      else
      {
        $("#business").hide();
      }
    });
});

Fiddle Demo

for me also the file_exists() function is not working properly. So I got this alternative solution. Hope this one help someone

$path = 'http://localhost/admin/public/upload/video_thumbnail/thumbnail_1564385519_0.png';

    if (@GetImageSize($path)) {
        echo 'File exits';
    } else {
        echo "File doesn't exits";
    }

For those having trouble receiving the request on a php page using $_POST because you expect key-value pairs:

While all the answers where very helpful, I lacked some basic understanding on which string actually to post, since in the old apache HttpClient I used

new UrlEncodedFormEntity(nameValuePairs); (Java)

and then could use $_POST in php do get the key-value pairs.

To my understanding now one has build that string manually before posting. So the string needs to look like

val data = "key1=val1&key2=val2"

but instead just adding it to the url it is posted (in the header).

The alternative would be to use a json-string instead:

val data = "{\"key1\":\"val1\",\"key2\":\"val2\"}" // {"key1":"val1","key2":"val2"}

and pull it in php without $_POST:

$json_params = file_get_contents('php://input');
// echo_p("Data: $json_params");
$data = json_decode($json_params, true);

Here you find a sample code in Kotlin:

class TaskDownloadTest : AsyncTask<Void, Void, Void>() {
    override fun doInBackground(vararg params: Void): Void? {
        var urlConnection: HttpURLConnection? = null

        try {

            val postData = JsonObject()

upstream in the github example is just the name they've chosen to refer to that repository. You may choose any that you like when using git remote add. Depending on what you select for this name, your git pull usage will change. For example, if you use:

git remote add upstream git://github.com/somename/original-project.git

then you would use this to pull changes:

git pull upstream master

But, if you choose origin for the name of the remote repo, your commands would be:

To name the remote repo in your local config: git remote add origin git://github.com/somename/original-project.git

And to pull: git pull origin master

SELECT phone, phone2 
FROM jewishyellow.users 
WHERE phone like '813%' and (phone2 <> "");

May need some tweakage depending on what your default value is. If you allowed Null fill, then you can do "Not NULL" instead, which is obviously better.

try this code below :

var currentLocation = document.location;
muzLoc = String(currentLocation).substring(0,45);
prodLoc = String(currentLocation).substring(0,48); 
techLoc = String(currentLocation).substring(0,47);
