Another simple example is to do a safe-thread modification in a session object.

public PlayerScore getHighScore() {
    ServletContext ctx = getServletConfig().getServletContext();
    AtomicReference<PlayerScore> holder 
        = (AtomicReference<PlayerScore>) ctx.getAttribute("highScore");
    return holder.get();
}

public void updateHighScore(PlayerScore newScore) {
    ServletContext ctx = getServletConfig().getServletContext();
    AtomicReference<PlayerScore> holder 
        = (AtomicReference<PlayerScore>) ctx.getAttribute("highScore");
    while (true) {
        HighScore old = holder.get();
        if (old.score >= newScore.score)
            break;
        else if (holder.compareAndSet(old, newScore))
            break;
    } 
}

expression is your friend:

plot(1,1, main=expression('title'[2])) #subscript

In oracle db there is a trick for casting int to float (I suppose, it should also work in mysql):

select myintfield + 0.0 as myfloatfield from mytable

While @Heximal's answer works, I don't personally recommend it.

This is because it uses implicit casting. Although you didn't type CAST, either the SUM() or the 0.0 need to be cast to be the same data-types, before the + can happen. In this case the order of precedence is in your favour, and you get a float on both sides, and a float as a result of the +. But SUM(aFloatField) + 0 does not yield an INT, because the 0 is being implicitly cast to a FLOAT.

I find that in most programming cases, it is much preferable to be explicit. Don't leave things to chance, confusion, or interpretation.

If you want to be explicit, I would use the following.

CAST(SUM(sl.parts) AS FLOAT) * cp.price
-- using MySQL CAST FLOAT  requires 8.0

You can try the following to see what happens...

CAST(SUM(sl.parts) AS NUMERIC(10,4)) * CAST(cp.price AS NUMERIC(10,4))

Here's one slight alteration to the answers of a query that creates the table upon execution (i.e. you don't have to create the table first):

SELECT * INTO #Temp
FROM (
select OptionNo, OptionName from Options where OptionActive = 1
) as X

This did the trick for me:

var express = require('express'),
app = express(); 
app.use('/', express.static(__dirname + '/'));
app.listen(8080);

I am sure this code will surely resolve your issues...This is working fine for me...\

Putting together several answers from above, this is what I ended up using:

var validationErrors = ModelState.Values.Where(E => E.Errors.Count > 0)
    .SelectMany(E => E.Errors)
    .Select(E => E.ErrorMessage)
    .ToList();

validationErrors ends up being a List<string> that contains each error message. From there, it's easy to do what you want with that list.

"<name> <substring>"[/.*<([^>]*)/,1]
=> "substring"

No need to use scan, if we need only one result.
No need to use Python's match, when we have Ruby's String[regexp,#].

See: http://ruby-doc.org/core/String.html#method-i-5B-5D

Note: str[regexp, capture] ? new_str or nil

Some awk version.

awk '/19:55/{c=5} c-->0'
awk '/19:55/{c=5} c && c--'

When pattern found, set c=5
If c is true, print and decrease number of c

I use Checkstlye plugin for such a purpose. In Checkstyle configuration, I add special regexp rules to detect lines with TABs and then mark such lines as checkstyle ERROR, which is clearly visible in Eclipse editor. Works fine.

Remember to check firewall settings as well. after checking and double-checking my pg_hba.conf and postgres.conf files I finally found out that my firewall was overriding everything and therefore blocking connections

The message that you are getting is not for the default Exception of Python:

For a fresh python list, IndexError is thrown only on index not being in range (even docs say so).

>>> l = []
>>> l[1]
IndexError: list index out of range

If we try passing multiple items to list, or some other value, we get the TypeError:

>>> l[1, 2]
TypeError: list indices must be integers, not tuple

>>> l[float('NaN')]
TypeError: list indices must be integers, not float

However, here, you seem to be using matplotlib that internally uses numpy for handling arrays. On digging deeper through the codebase for numpy, we see:

static NPY_INLINE npy_intp
unpack_tuple(PyTupleObject *index, PyObject **result, npy_intp result_n)
{
    npy_intp n, i;
    n = PyTuple_GET_SIZE(index);
    if (n > result_n) {
        PyErr_SetString(PyExc_IndexError,
                        "too many indices for array");
        return -1;
    }
    for (i = 0; i < n; i++) {
        result[i] = PyTuple_GET_ITEM(index, i);
        Py_INCREF(result[i]);
    }
    return n;
}

where, the unpack method will throw an error if it the size of the index is greater than that of the results.

So, Unlike Python which raises a TypeError on incorrect Indexes, Numpy raises the IndexError because it supports multidimensional arrays.

If your only requirement in your custom serializer is to skip serializing the name field of User, mark it as transient. Jackson will not serialize or deserialize transient fields.

I had this same error when I migrated a Wordpress site to another server. The URL in the header for my js scripts was still pointing to the old server and domain name.

Once I updated the domain name, the error went away.

I'm on Ubuntu 15.04. This seemed to work:

$ sudo pip3 install numpy

On RHEL this worked:

$ sudo python3 -m pip install numpy

Try this instead

$.unbind('scroll');

There is already an ISO standard for this; no need to invent your own scheme:

http://en.wikipedia.org/wiki/ISO_5218

Per the standard, the column should be called "Sex" and the 'closest' data type would be tinyint with a CHECK constraint or lookup table as appropriate.

Pass the sheet name with the Range parameter of the DoCmd.TransferSpreadsheet Method. See the box titled "Worksheets in the Range Parameter" near the bottom of that page.

This code imports from a sheet named "temp" in a workbook named "temp.xls", and stores the data in a table named "tblFromExcel".

Dim strXls As String
strXls = CurrentProject.Path & Chr(92) & "temp.xls"
DoCmd.TransferSpreadsheet acImport, , "tblFromExcel", _
    strXls, True, "temp!"

The solution that worked for me was here: https://serverfault.com/questions/334284/cant-create-pid-file-on-mysql-server-permission-denied

Changing some of my permissions seemed to do the trick. I'm running a Mid-2012 Macbook Air with OS X 10.8.2 and mysql was installed with homebrew.

chmod 0755 /var
chown root:wheel /var/tmp
sudo chmod 0771 /usr/local/var/mysql/*

You can use the "auto" value for the left and right margins to let the browser distribute the available space equally at both sides of the inner div:

<div id='parent' style='width: 100%;'>
   <div id='child' style='width: 50px; height: 100px; margin-left: auto; margin-right: auto'>Text</div>
</div>

very simple

In the address bar of your web browser, type the following URL and press the Enter key to retrieve information of a GitHub repository.

https://api.github.com/repos/{:owner}/{:repository}

Note! In the URL above, replace the {:owner} and {:repository} parts with the values that can be found in the URL of the GitHub repository for which you want to know the creation date. For example, if the URL of the repository is https://github.com/ArthurGareginyan/batch-rename/, then the URL of it’s information will be https://api.github.com/repos/ArthurGareginyan/batch-rename.

output:

you can use native stringify function like this

const j={ "name": "binchen" }_x000D_
_x000D_
/** convert json to string */_x000D_
const jsonString = JSON.stringify(j)_x000D_
_x000D_
console.log(jsonString) // {"name":"binchen"}

Using lodash library it is simple as this

_.remove(myArray , { field: 'money' });

$timestamp='2014-11-21 16:38:00';

list($date,$time)=explode(' ',$timestamp);

// just time

preg_match("/ (\d\d:\d\d):\d\d$/",$timestamp,$match);
echo "\n<br>".$match[1];

File sdCard = Environment.getExternalStorageDirectory();
File dir = new File (sdCard.getAbsolutePath() + "/dir1/dir2");
dir.mkdirs();
File file = new File(dir, "filename");

none of answers helped me, in case when I had several levels of nested arrays. the solution is almost same as @AlienWebguy already did, but with tiny difference.

function nestedToSingle(array $array)
{
    $singleDimArray = [];

    foreach ($array as $item) {

        if (is_array($item)) {
            $singleDimArray = array_merge($singleDimArray, nestedToSingle($item));

        } else {
            $singleDimArray[] = $item;
        }
    }

    return $singleDimArray;
}

test example

$array = [
        'first',
        'second',
        [
            'third',
            'fourth',
        ],
        'fifth',
        [
            'sixth',
            [
                'seventh',
                'eighth',
                [
                    'ninth',
                    [
                        [
                            'tenth'
                        ]
                    ]
                ],
                'eleventh'
            ]
        ],
        'twelfth'
    ];

    $array = nestedToSingle($array);
    print_r($array);

    //output
    array:12 [
        0 => "first"
        1 => "second"
        2 => "third"
        3 => "fourth"
        4 => "fifth"
        5 => "sixth"
        6 => "seventh"
        7 => "eighth"
        8 => "ninth"
        9 => "tenth"
        10 => "eleventh"
        11 => "twelfth"
   ]

Every programming language has its own set of rules and conventions for the kinds of names that you're allowed to use, and the Java programming language is no different. The rules and conventions for naming your variables can be summarized as follows:

• Variable names are case-sensitive. A variable's name can be any legal identifier — an unlimited-length sequence of Unicode letters and digits, beginning with a letter, the dollar sign "$", or the underscore character "_". The convention, however, is to always begin your variable names with a letter, not "$" or "_". Additionally, the dollar sign character, by convention, is never used at all. You may find some situations where auto-generated names will contain the dollar sign, but your variable names should always avoid using it. A similar convention exists for the underscore character; while it's technically legal to begin your variable's name with "_", this practice is discouraged. White space is not permitted.

• Subsequent characters may be letters, digits, dollar signs, or underscore characters. Conventions (and common sense) apply to this rule as well. When choosing a name for your variables, use full words instead of cryptic abbreviations. Doing so will make your code easier to read and understand. In many cases it will also make your code self-documenting; fields named cadence, speed, and gear, for example, are much more intuitive than abbreviated versions, such as s, c, and g. Also keep in mind that the name you choose must not be a keyword or reserved word.

• If the name you choose consists of only one word, spell that word in all lowercase letters. If it consists of more than one word, capitalize the first letter of each subsequent word. The names gearRatio and currentGear are prime examples of this convention. If your variable stores a constant value, such as static final int NUM_GEARS = 6, the convention changes slightly, capitalizing every letter and separating subsequent words with the underscore character. By convention, the underscore character is never used elsewhere.

1.> Change File format to .CSV (semicolon delimited)

To achieve the desired result we need to temporary change the delimiter setting in the Excel Options:

Move to File -> Options -> Advanced -> Editing Section

Uncheck the “Use system separators” setting and put a comma in the “Decimal Separator” field.

Now save the file in the .CSV format and it will be saved in the semicolon delimited format.

You cannot undo the latest git add, but you can undo all adds since the last commit. git reset without a commit argument resets the index (unstages staged changes):

Without JQuery (2017)

Because you might not need JQuery, here is a working Vanilla JS version based on @StanleyH answer:

var wrapper1 = document.getElementById('wrapper1');_x000D_
var wrapper2 = document.getElementById('wrapper2');_x000D_
wrapper1.onscroll = function() {_x000D_
  wrapper2.scrollLeft = wrapper1.scrollLeft;_x000D_
};_x000D_
wrapper2.onscroll = function() {_x000D_
  wrapper1.scrollLeft = wrapper2.scrollLeft;_x000D_
};

ifstream inFile;
string name, temp;
int age;

inFile.open("file.txt");

getline(inFile, name, ' '); // use ' ' as separator, default is '\n' (newline). Now name is "John".
getline(inFile, temp, ' '); // Now temp is "Smith"
name.append(1,' ');
name += temp;
inFile >> age; 

cout << name << endl;
cout << age << endl;  

inFile.close();    

From where would you get these values? If they're from the button itself, you could just do

commentbtn.click(function() {
   alert(this.id);
});

If they're a variable in the binding scope, you can access them from without

var id = 1;
commentbtn.click(function() {
   alert(id);
});

If they're a variable in the binding scope, that might change before the click is called, you'll need to create a new closure

for(var i = 0; i < 5; i++) {
   $('#button'+i).click((function(id) {
      return function() {
         alert(id);
      };
   }(i)));
}

There is no keyword for such type checks, but you can put some code in that will at least fail in an orderly fashion:

(1) If you want a function template to only accept parameters of a certain base class X, assign it to a X reference in your function. (2) If you want to accept functions but not primitives or vice versa, or you want to filter classes in other ways, call a (empty) template helper function within your function that's only defined for the classes you want to accept.

You can use (1) and (2) also in member functions of a class to force these type checks on the entire class.

You can probably put it into some smart Macro to ease your pain. :)

Since c++11 we could use list initialization:

char* c = new char[length]{};

For an aggregate type, then aggregate initialization will be performed, which has the same effect like char c[2] = {};.

You initialized and declared your String to "Hi there", initialized your char[] array with the correct size, and you began a loop over the length of the array which prints an empty string combined with a given element being looked at in the array. At which point did you factor in the functionality to put in the characters from the String into the array?

When you attempt to print each element in the array, you print an empty String, since you're adding 'nothing' to an empty String, and since there was no functionality to add in the characters from the input String to the array. You have everything around it correctly implemented, though. This is the code that should go after you initialize the array, but before the for-loop that iterates over the array to print out the elements.

for (int count = 0; count < ini.length(); count++) {
  array[count] = ini.charAt(count);
}

It would be more efficient to just combine the for-loops to print each character out right after you put it into the array.

for (int count = 0; count < ini.length(); count++) {
  array[count] = ini.charAt(count);
  System.out.println(array[count]);
}

At this point, you're probably wondering why even put it in a char[] when I can just print them using the reference to the String object ini itself.

String ini = "Hi there";

for (int count = 0; count < ini.length(); count++) {
   System.out.println(ini.charAt(count));
}

Definitely read about Java Strings. They're fascinating and work pretty well, in my opinion. Here's a decent link: https://www.javatpoint.com/java-string

String ini = "Hi there"; // stored in String constant pool

is stored differently in memory than

String ini = new String("Hi there"); // stored in heap memory and String constant pool

, which is stored differently than

char[] inichar = new char[]{"H", "i", " ", "t", "h", "e", "r", "e"};
String ini = new String(inichar); // converts from char array to string

.

You have to initialise the object (create the object itself) in order to be able to call its methods otherwise you would get a NullPointerException.

WordList words = new WordList();

While everyone else has suggested the de facto time module, I thought I'd share a different method using matplotlib's pyplot function, pause.

An example

from matplotlib import pyplot as plt
plt.pause(5)    # Pauses the program for 5 seconds

Typically this is used to prevent the plot from disappearing as soon as it is plotted or to make crude animations.

This would save you an import if you already have matplotlib imported.

For Bootstrap 4, use the below code:

Tip for MULTIPLE VIDEOS on a page: I recently solved an issue with no mp4 playback in Chrome or Firefox (played fine in IE) in a page with 16 videos in modals (bootstrap 3) after discovering the frame rates of all the videos must be identical. I had 6 videos at 25fps and 12 at 29.97fps... after rendering all to 25fps versions, everything runs smooth across all browsers.

To find the size of an array use the scalar keyword:

print scalar @array;

To find out the last index of an array there is $# (Perl default variable). It gives the last index of an array. As an array starts from 0, we get the size of array by adding one to $#:

print "$#array+1";

Example:

my @a = qw(1 3 5);
print scalar @a, "\n";
print $#a+1, "\n";

Output:

3

assylias and Head of Catering have already given your the reason why the error is occurring.

Now regarding what you are doing, from what I understand, you don't need to use Select at all

I guess you are doing this from VBA PowerPoint? If yes, then your code be rewritten as

Dim sourceXL As Object, sourceBook As Object
Dim sourceSheet As Object, sourceSheetSum As Object
Dim lRow As Long
Dim measName As Variant, partName As Variant
Dim filepath As String

filepath = CStr(FileDialog)

'~~> Establish an EXCEL application object
On Error Resume Next
Set sourceXL = GetObject(, "Excel.Application")

'~~> If not found then create new instance
If Err.Number <> 0 Then
    Set sourceXL = CreateObject("Excel.Application")
End If
Err.Clear
On Error GoTo 0

Set sourceBook = sourceXL.Workbooks.Open(filepath)
Set sourceSheet = sourceBook.Sheets("Measurements")
Set sourceSheetSum = sourceBook.Sheets("Analysis Summary")

lRow = sourceSheetSum.Range("C" & sourceSheetSum.Rows.Count).End(xlUp).Row
measName = sourceSheetSum.Range("C3:C" & lRow)

lRow = sourceSheetSum.Range("D" & sourceSheetSum.Rows.Count).End(xlUp).Row
partName = sourceSheetSum.Range("D3:D" & lRow)

You can also use a fadeIn/FadeOut Combo, too....

$('.test').bind('click', function(){
    $('.div1').fadeIn(500); 
    $('.div2').fadeOut(500);
    $('.div3').fadeOut(500);
    return false;
});

msg = request.GET.get('q','default')
if (msg == default):
    message = "YOU SUBMITTED NOTHING"
else: 
    message = "you submitted = %s" %msg"
return HttpResponse(message);

I sometimes do a mysqldump and pipe the output into another mysql command to import it into a different database.

mysqldump --add-drop-table -u wordpress -p wordpress | mysql -u wordpress -p wordpress_backup

use "rb" to open a binary file. Then the bytes of the file won't be encoded when you read them

selinux is cause for that problem.....

TException: Error: TSocket: Could not connect to localhost:9160 (Permission denied [13]) To resolve it, you need to change an SELinux boolean value (which will automatically persist across reboots). You may also want to restart httpd to reset the proxy worker, although this isn't strictly required.

setsebool -P httpd_can_network_connect 1

or

(13) Permission Denied

Error 13 indicates a filesystem permissions problem. That is, Apache was denied access to a file or directory due to incorrect permissions. It does not, in general, imply a problem in the Apache configuration files.

In order to serve files, Apache must have the proper permission granted by the operating system to access those files. In particular, the User or Group specified in httpd.conf must be able to read all files that will be served and search the directory containing those files, along with all parent directories up to the root of the filesystem.

Typical permissions on a unix-like system for resources not owned by the User or Group specified in httpd.conf would be 644 -rw-r--r-- for ordinary files and 755 drwxr-x-r-x for directories or CGI scripts. You may also need to check extended permissions (such as SELinux permissions) on operating systems that support them.

An Example

Lets say that you received the Permission Denied error when accessing the file /usr/local/apache2/htdocs/foo/bar.html on a unix-like system.

First check the existing permissions on the file:

cd /usr/local/apache2/htdocs/foo ls -l bar.htm

Fix them if necessary:

chmod 644 bar.html

Then do the same for the directory and each parent directory (/usr/local/apache2/htdocs/foo, /usr/local/apache2/htdocs, /usr/local/apache2, /usr/local, /usr):

ls -la chmod +x . cd ..

repeat up to the root

On some systems, the utility namei can be used to help find permissions problems by listing the permissions along each component of the path:

namei -m /usr/local/apache2/htdocs/foo/bar.html

If all the standard permissions are correct and you still get a Permission Denied error, you should check for extended-permissions. For example you can use the command setenforce 0 to turn off SELinux and check to see if the problem goes away. If so, ls -alZ can be used to view SELinux permission and chcon to fix them.

In rare cases, this can be caused by other issues, such as a file permissions problem elsewhere in your apache2.conf file. For example, a WSGIScriptAlias directive not mapping to an actual file. The error message may not be accurate about which file was unreadable.

DO NOT set files or directories to mode 777, even "just to test", even if "it's just a test server". The purpose of a test server is to get things right in a safe environment, not to get away with doing it wrong. All it will tell you is if the problem is with files that actually exist.

Anonymous types allow you to select arbitrary fields into data structures that are strongly typed later on in your code:

var cats = listObject
    .Select(i => new { i.category_id, i.category_name })
    .Distinct()
    .OrderByDescending(i => i.category_name)
    .ToArray();

Since you (apparently) need to store it for later use, you could use the GroupBy operator:

Data[] cats = listObject
    .GroupBy(i => new { i.category_id, i.category_name })
    .OrderByDescending(g => g.Key.category_name)
    .Select(g => g.First())
    .ToArray();

I got solution after working whole day on it. It is little hacky solution Added span inside td tag

<td><span><%= item.StartICDate %></span></td>. 

Date format which Im using is dd/MM/YYYY. Tested in Datatables1.9.0

If you wanna maintain the same order in your list, say: your Map looks like:

map.put(1, "msg1")
map.put(2, "msg2")
map.put(3, "msg3")

and you want your list looks like

["msg1", "msg2", "msg3"]   // same order as the map

you will have to iterate through the Map:

// sort your map based on key, otherwise you will get IndexOutofBoundException
Map<String, String> treeMap = new TreeMap<String, String>(map)

List<String> list = new List<String>();
for (treeMap.Entry<Integer, String> entry : treeMap.entrySet()) {
    list.add(entry.getKey(), entry.getValue());
}  

Yes! You can use the new Visual Studio for Mac, which Microsoft launched in November.

Yes. I also think that using read() with arguments like read(Char[], int init, int end) is a better way to read a such a large file (Eg : read(buffer,0,buffer.length))

And I also experienced the problem of missing values of using the BufferedReader instead of BufferedInputStreamReader for a binary data input stream. So, using the BufferedInputStreamReader is a much better in this like case.

I used something like that

$(yourSelector).find('input:checkbox').removeAttr('checked');

You should look at charAt function and take length of the string.

var b = 'I am a JavaScript hacker.';
console.log(b.charAt(b.length-1));

@Silverstorm

I had Hyperv installed and virtualization enabled in my BIOS.

But SOLUTION A didn't work for me.

However, SOLUTION B worked like a charm.

SOLUTION B (If Hyper-V feature is already enabled but doesn't work)

Enable Hypervisor with

bcdedit /set hypervisorlaunchtype auto Now restart the system and try again.

You can use the regex "\W".This matches any non-word character.The required line would be:

String[] tokens=pdfName.split("\\W");

As the accepted answer requires you to add a Frame Layout, here how you can do it with material design.

Add this if you haven't already

implementation 'com.google.android.material:material:1.0.0'

Now change to Cardview to MaterialCardView

<com.google.android.material.card.MaterialCardView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="16dp"
app:cardCornerRadius="8dp"
app:cardElevation="2dp"

app:strokeWidth="1dp"
app:strokeColor="@color/black">

Now you need to change the activity theme to Theme.Material. If you are using Theme.Appcompact I will suggest you to move to Theme.Material for future projects for having better material design in you app.

    <style name="AppTheme" parent="Theme.MaterialComponents.DayNight">

For people with only one IP address and multiple sites on one server, you can configure IIS to listen on a port other than 80, e.g 8080 by setting the TCP port in the properties of each of its sites (including the default one).

In Apache, enable mod_proxy and mod_proxy_http, then add a catch-all VirtualHost (after all others) so that requests Apache isn't explicitly handling get "forwarded" on to IIS.

<VirtualHost *:80>
    ServerName foo.bar
    ServerAlias *
    ProxyPreserveHost On
    ProxyPass / http://127.0.0.1:8080/
</VirtualHost>

Now you can have Apache serve some sites and IIS serve others, with no visible difference to the user.

Edit: your IIS sites must not include their port number in any URLs within their responses, including headers.

1. Go to File -> Invalidate Caches/Restart.
2. Close the project.
3. Go to project folder and delete .idea folder.
4. Delete YourProjectName.iml in project folder.
5. Delete app.iml in app folder.
6. Open Android studio -> open existing project, and then select your project.
7. The Load Settings error and Unsupported modules detected error will be gone.

A4 size is 210x297mm

So you can set the HTML page to fit those sizes with CSS:

html,body{
    height:297mm;
    width:210mm;
}

This is the bit of code you need at the top of your JavaScript file:

<?php
    header('Content-Type: text/javascript; charset=UTF-8');
?>

(function() {
    alert("hello world");
}) ();

To get the n most frequent values, just subset .value_counts() and grab the index:

# get top 10 most frequent names
n = 10
dataframe['name'].value_counts()[:n].index.tolist()

I know this is an old post, but a good time to use PrimaryKeyColumn would be if you wanted a unidirectional relationship or had multiple tables all sharing the same id.

In general this is a bad idea and it would be better to use foreign key relationships with JoinColumn.

Having said that, if you are working on an older database that used a system like this then that would be a good time to use it.

Checking if v contains the element x:

#include <algorithm>

if(std::find(v.begin(), v.end(), x) != v.end()) {
    /* v contains x */
} else {
    /* v does not contain x */
}

Checking if v contains elements (is non-empty):

if(!v.empty()){
    /* v is non-empty */
} else {
    /* v is empty */
}

The steel is far from hot, but I combined @abatishchev's solution with the answer from this post and got to this result. Hope it's useful:

public static class GlobalVars
{
    private const string GlobalKey = "AllMyVars";

    static GlobalVars()
    {
        Hashtable table = HttpContext.Current.Application[GlobalKey] as Hashtable;

        if (table == null)
        {
            table = new Hashtable();
            HttpContext.Current.Application[GlobalKey] = table;
        }
    }

    public static Hashtable Vars
    {
        get { return HttpContext.Current.Application[GlobalKey] as Hashtable; }
    }

    public static IEnumerable<SomeClass> SomeCollection
    {
        get { return GetVar("SomeCollection") as IEnumerable<SomeClass>; }
        set { WriteVar("SomeCollection", value); }
    }

    internal static DateTime SomeDate
    {
        get { return (DateTime)GetVar("SomeDate"); }
        set { WriteVar("SomeDate", value); }
    }

    private static object GetVar(string varName)
    {
        if (Vars.ContainsKey(varName))
        {
            return Vars[varName];
        }

        return null;
    }

    private static void WriteVar(string varName, object value)
    {
        if (value == null)
        {
            if (Vars.ContainsKey(varName))
            {
                Vars.Remove(varName);
            }
            return;
        }

        if (Vars[varName] == null)
        {
            Vars.Add(varName, value);
        }
        else
        {
            Vars[varName] = value;
        }
    }
}

Setting "expires" to a past date is the standard way to delete a cookie.

Your problem is probably because the date format is not conventional. IE probably expects GMT only.

group by default order by pk id,so the result
username point avg_time
demo123 100 90 ---> id = 4
demo123456 100 100 ---> id = 7
demo 90 120 ---> id = 1

I had the same problem. Debugging does not work with the stuff that comes with the OpenCV executable. you have to build your own binarys.
Then enable Microsoft Symbol Servers in Debug->options and settings->debug->symbols

The for attribute shows that this label stands for related input field, or check box or radio button or any other data entering field associated with it. for example

            <input type="text" id="BlindCopy" name="BlindCopy" class="splitblindcopy" />

</li>

An alternative approach is to rename the 'old' origin (in the example below I name it simply old-origin) and adding a new one. This might be the desired approach if you still want to be able to push to the old origin every now and then:

git remote rename origin old-origin
git remote add origin [email protected]>:<username>/<projectname>.git

And in case you need to push your local state to the new origin:

git push -u origin --all
git push -u origin --tags

I keep hitting this answer. But none of them list the easiest solution for xsltproc (and probably most XSLT 1.0 processors):

1. Add the exslt strings name to the stylesheet, i.e.:

<xsl:stylesheet
  version="1.0"
  xmlns:str="http://exslt.org/strings"
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

2. Then use it like:

<xsl:value-of select="str:replace(., ' ', '')"/>

You could add android:textAllCaps="false" to the button.

The button text might be transformed to uppercase by your app's theme that applies to all buttons. Check themes / styles files for setting the attribute android:textAllCaps.

First of all thanks @Arvis for an eye opening explanation.

I prefer different solution to the accepted answer here for this problem. I don't like messing with overriding back behavior any more than absolutely necessary and when I've tried adding and removing fragments on my own without default back stack poping when back button is pressed I found my self in fragment hell :) If you .add f2 over f1 when you remove it f1 won't call any of callback methods like onResume, onStart etc. and that can be very unfortunate.

Anyhow this is how I do it:

Currently on display is only fragment f1.

f1 -> f2

Fragment2 f2 = new Fragment2();
this.getActivity().getSupportFragmentManager().beginTransaction().replace(R.id.main_content,f2).addToBackStack(null).commit();

nothing out of the ordinary here. Than in fragment f2 this code takes you to fragment f3.

f2 -> f3

Fragment3 f3 = new Fragment3();
getActivity().getSupportFragmentManager().popBackStack();
getActivity().getSupportFragmentManager().beginTransaction().replace(R.id.main_content, f3).addToBackStack(null).commit();

I'm not sure by reading docs if this should work, this poping transaction method is said to be asynchronous, and maybe a better way would be to call popBackStackImmediate(). But as far I can tell on my devices it's working flawlessly.

The said alternative would be:

final FragmentActivity activity = getActivity();
activity.getSupportFragmentManager().popBackStackImmediate();
activity.getSupportFragmentManager().beginTransaction().replace(R.id.main_content, f3).addToBackStack(null).commit();

Here there will actually be brief going back to f1 beofre moving on to f3, so a slight glitch there.

This is actually all you have to do, no need to override back stack behavior...

You can take a look here for a longer list of screen sizes and respective media queries.

Or go for Bootstrap media queries:

/* Large desktop */
@media (min-width: 1200px) { ... }

/* Portrait tablet to landscape and desktop */
@media (min-width: 768px) and (max-width: 979px) { ... }

/* Landscape phone to portrait tablet */
@media (max-width: 767px) { ... }

/* Landscape phones and down */
@media (max-width: 480px) { ... }

Additionally you might wanty to take a look at Foundation's media queries with the following default settings:

// Media Queries

$screenSmall: 768px !default;
$screenMedium: 1279px !default;
$screenXlarge: 1441px !default;

In case someone cares just about the error nothing added to commit but untracked files present (use "git add" to track) and not about Please move or remove them before you can merge.. You might have a look at the answers on Git - Won't add files?

There you find at least 2 good candidates for the issue in question here: that you either are in a subfolder or in a parent folder, but not in the actual repo folder. If you are in the directory one level too high, this will definitely raise that message "nothing added to commit…", see my answer in the link for details. I do not know if the same message occurs when you are in a subfolder, but it is likely. That could fit to your explanations.

If I understand you right, you can do this:

<img src="image.png" style="background-color:red;" />

In fact, you can even apply a whole background-image to the image, resulting in two "layers" without the need for multi-background support in the browser ;)

Contrary to the suggestions by some of the other answers, using the DllImport attribute is still the correct approach.

I honestly don't understand why you can't do just like everyone else in the world and specify a relative path to your DLL. Yes, the path in which your application will be installed differs on different people's computers, but that's basically a universal rule when it comes to deployment. The DllImport mechanism is designed with this in mind.

In fact, it isn't even DllImport that handles it. It's the native Win32 DLL loading rules that govern things, regardless of whether you're using the handy managed wrappers (the P/Invoke marshaller just calls LoadLibrary). Those rules are enumerated in great detail here, but the important ones are excerpted here:

Before the system searches for a DLL, it checks the following:

• If a DLL with the same module name is already loaded in memory, the system uses the loaded DLL, no matter which directory it is in. The system does not search for the DLL.
• If the DLL is on the list of known DLLs for the version of Windows on which the application is running, the system uses its copy of the known DLL (and the known DLL's dependent DLLs, if any). The system does not search for the DLL.

---

If SafeDllSearchMode is enabled (the default), the search order is as follows:

1. The directory from which the application loaded.
2. The system directory. Use the GetSystemDirectory function to get the path of this directory.
3. The 16-bit system directory. There is no function that obtains the path of this directory, but it is searched.
4. The Windows directory. Use the GetWindowsDirectory function to get the path of this directory.
5. The current directory.
6. The directories that are listed in the PATH environment variable. Note that this does not include the per-application path specified by the App Paths registry key. The App Paths key is not used when computing the DLL search path.

So, unless you're naming your DLL the same thing as a system DLL (which you should obviously not be doing, ever, under any circumstances), the default search order will start looking in the directory from which your application was loaded. If you place the DLL there during the install, it will be found. All of the complicated problems go away if you just use relative paths.

Just write:

[DllImport("MyAppDll.dll")] // relative path; just give the DLL's name
static extern bool MyGreatFunction(int myFirstParam, int mySecondParam);

But if that doesn't work for whatever reason, and you need to force the application to look in a different directory for the DLL, you can modify the default search path using the SetDllDirectory function.
Note that, as per the documentation:

After calling SetDllDirectory, the standard DLL search path is:

1. The directory from which the application loaded.
2. The directory specified by the lpPathName parameter.
3. The system directory. Use the GetSystemDirectory function to get the path of this directory.
4. The 16-bit system directory. There is no function that obtains the path of this directory, but it is searched.
5. The Windows directory. Use the GetWindowsDirectory function to get the path of this directory.
6. The directories that are listed in the PATH environment variable.

So as long as you call this function before you call the function imported from the DLL for the first time, you can modify the default search path used to locate DLLs. The benefit, of course, is that you can pass a dynamic value to this function that is computed at run-time. That isn't possible with the DllImport attribute, so you will still use a relative path (the name of the DLL only) there, and rely on the new search order to find it for you.

You'll have to P/Invoke this function. The declaration looks like this:

[DllImport("kernel32.dll", CharSet = CharSet.Auto, SetLastError = true)]
static extern bool SetDllDirectory(string lpPathName);

I had a similar issue with Intellij. The issue was that someone added the file that I am trying to compare in Intellij to .gitignore, without actually deleting the file from Git.

In my build.gradle, I resolved this issue by creating a task and then specifying the "mainClassName" as follows:

task(runSimpleXYZProgram, group: 'algorithms', description: 'Description of what your program does', dependsOn: 'classes', type: JavaExec) {
    mainClassName = 'your.entire.package.classContainingYourMainMethod'
}

You can use Hibernate Dialect API for Database independence as follow

class SequenceValueGetter {
    private SessionFactory sessionFactory;

    // For Hibernate 3
    public Long getId(final String sequenceName) {
        final List<Long> ids = new ArrayList<Long>(1);

        sessionFactory.getCurrentSession().doWork(new Work() {
            public void execute(Connection connection) throws SQLException {
                DialectResolver dialectResolver = new StandardDialectResolver();
                Dialect dialect =  dialectResolver.resolveDialect(connection.getMetaData());
                PreparedStatement preparedStatement = null;
                ResultSet resultSet = null;
                try {
                    preparedStatement = connection.prepareStatement( dialect.getSequenceNextValString(sequenceName));
                    resultSet = preparedStatement.executeQuery();
                    resultSet.next();
                    ids.add(resultSet.getLong(1));
                }catch (SQLException e) {
                    throw e;
                } finally {
                    if(preparedStatement != null) {
                        preparedStatement.close();
                    }
                    if(resultSet != null) {
                        resultSet.close();
                    }
                }
            }
        });
        return ids.get(0);
    }

    // For Hibernate 4
    public Long getID(final String sequenceName) {
        ReturningWork<Long> maxReturningWork = new ReturningWork<Long>() {
            @Override
            public Long execute(Connection connection) throws SQLException {
                DialectResolver dialectResolver = new StandardDialectResolver();
                Dialect dialect =  dialectResolver.resolveDialect(connection.getMetaData());
                PreparedStatement preparedStatement = null;
                ResultSet resultSet = null;
                try {
                    preparedStatement = connection.prepareStatement( dialect.getSequenceNextValString(sequenceName));
                    resultSet = preparedStatement.executeQuery();
                    resultSet.next();
                    return resultSet.getLong(1);
                }catch (SQLException e) {
                    throw e;
                } finally {
                    if(preparedStatement != null) {
                        preparedStatement.close();
                    }
                    if(resultSet != null) {
                        resultSet.close();
                    }
                }

            }
        };
        Long maxRecord = sessionFactory.getCurrentSession().doReturningWork(maxReturningWork);
        return maxRecord;
    }

}

You could try adding a bool so the algorithm would know when the button was activated. When it's clicked, the bool checks true, the new form shows and the last gets closed.

It's important to know that forms consume some ram (at least a little bit), so it's a good idea to close those you're not gonna use, instead of just hiding it. Makes the difference in big projects.

A gc-friendly piece of code:

public static<X> X[] arrayOfNotNull(X[] array) {
    for (int p=0, N=array.length; p<N; ++p) {
        if (array[p] == null) {
            int m=p; for (int i=p+1; i<N; ++i) if (array[i]!=null) ++m;
            X[] res = Arrays.copyOf(array, m);
            for (int i=p+1; i<N; ++i) if (array[i]!=null) res[p++] = array[i];
            return res;
        }
    }
    return array;
}

It returns the original array if it contains no nulls. It does not modify the original array.

<input type="number" oninput="this.value = this.value.replace(/[^0-9.]/g, ''); this.value = this.value.replace(/(\..*)\./g, '$1');" onKeyDown="if(this.value.length==10 && event.keyCode!=8) return false;">

I posted an answer to this already when someone else asked the same question (see How to bring back "Browser mode" in IE11?).

Read my answer there for a fuller explaination, but in short:

• They removed it deliberately, because compat mode is not actually really very good for testing compatibility.

• If you really want to test for compatibility with any given version of IE, you need to test in a real copy of that IE version. MS provide free VMs on http://modern.ie/ for you to use for this purpose.

• The only way to get compat mode in IE11 is to set the X-UA-Compatible header. When you have this and the site defaults to compat mode, you will be able to set the mode in dev tools, but only between edge or the specified compat mode; other modes will still not be available.

So I was having this problem, none of the other remedies worked. The error message was opaque, but checking dmesg was key:

[   10.118255] NVRM: API mismatch: the client has the version 410.79, but
           NVRM: this kernel module has the version 384.130.  Please
           NVRM: make sure that this kernel module and all NVIDIA driver
           NVRM: components have the same version.

However I had completely removed the 384 version, and removed any remaining kernel drivers nvidia-384*. But even after reboot, I was still getting this. Seeing this meant that the kernel was still compiled to reference 384, but was only finding 410. So I recompiled my kernel:

# uname -a # find the kernel it's using
Linux blah 4.13.0-43-generic #48~16.04.1-Ubuntu SMP Thu May 17 12:56:46 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
# update-initramfs -c -k 4.13.0-43-generic #recompile it
# reboot

And then it worked.

After removing 384, I still had 384 files in: /var/lib/dkms/nvidia-XXX/XXX.YY/4.13.0-43-generic/x86_64/module /lib/modules/4.13.0-43-generic/kernel/drivers

I recommend using the locate command (not installed by default) rather than searching the filesystem every time.

If you open the DMP file with an editor that can handle big files, you might be able to locate the areas where the schema names are mentioned. Just be sure not to change anything. It would be better if you opened a copy of the original dump.

I solved this using multer as suggested above, but they missed giving a full working example, on how to do this. Basically this can happen when you have a form group with enctype="multipart/form-data". Here's the HTML for the form I had:

<form action="/stats" enctype="multipart/form-data" method="post">
  <div class="form-group">
    <input type="file" class="form-control-file" name="uploaded_file">
    <input type="text" class="form-control" placeholder="Number of speakers" name="nspeakers">
    <input type="submit" value="Get me the stats!" class="btn btn-default">            
  </div>
</form>

And here's how to use multer to get the values and names of this form with Express.js and node.js:

var multer  = require('multer')
var upload = multer({ dest: './public/data/uploads/' })
app.post('/stats', upload.single('uploaded_file'), function (req, res) {
   // req.file is the name of your file in the form above, here 'uploaded_file'
   // req.body will hold the text fields, if there were any 
   console.log(req.file, req.body)
});

You can access a public/protected property using the data binding expression <%# myproperty %> as given below:

    <asp:Label ID="Label1" runat="server" Text="<%#CodeBehindVarPublic %>"></asp:Label>

you should call DataBind method, otherwise it can't be evaluated.

    public partial class WebForm1 : System.Web.UI.Page
    {
     public string CodeBehindVarPublic { get; set; }
      protected void Page_Load(object sender, EventArgs e)
        {
          CodeBehindVarPublic ="xyz";
       //you should call the next line  in case of using <%#CodeBehindVarPublic %>

          DataBind();
        }

}

fyi The code I ended up with:

IF UPDATE (QtyToRepair)
    begin
        INSERT INTO tmpQtyToRepairChanges (OrderNo, PartNumber, ModifiedDate, ModifiedUser, ModifiedHost, QtyToRepairOld, QtyToRepairNew)
        SELECT S.OrderNo, S.PartNumber, GETDATE(), SUSER_NAME(), HOST_NAME(), D.QtyToRepair, I.QtyToRepair FROM SCHEDULE S
        INNER JOIN Inserted I ON S.OrderNo = I.OrderNo and S.PartNumber = I.PartNumber
        INNER JOIN Deleted D ON S.OrderNo = D.OrderNo and S.PartNumber = D.PartNumber 
        WHERE I.QtyToRepair <> D.QtyToRepair
end

it's number_map[int(x)], you tried to actually call the map with one argument

I have created this simple function which you guys can use easily. You will need to pass the table-name ($tbl), table-field ($insertFieldsArr) against your inserting data, data array ($arr).

insert_batch('table',array('field1','field2'),$dataArray);

    function insert_batch($tbl,$insertFieldsArr,$arr){ $sql = array(); 
    foreach( $arr as $row ) {
        $strVals='';
        $cnt=0;
        foreach($insertFieldsArr as $key=>$val){
            if(is_array($row)){
                $strVals.="'".mysql_real_escape_string($row[$cnt]).'\',';
            }
            else{
                $strVals.="'".mysql_real_escape_string($row).'\',';
            }
            $cnt++;
        }
        $strVals=rtrim($strVals,',');
        $sql[] = '('.$strVals.')';
    }

    $fields=implode(',',$insertFieldsArr);
    mysql_query('INSERT INTO `'.$tbl.'` ('.$fields.') VALUES '.implode(',', $sql));
}

Had the same problem. Here’s what I did & it got me the results I wanted.

1. Go to the Terminal of Visual studio code.
2. Cd to the directory of the file that has the code you wrote and ran. Let's call the program " xx.cpp "
3. Type g++ xx.cpp -o a.out (creates an executable)
4. To run your program, type ./a.out

No need of any manual break in code. Just add \n where you want to break.

alert ("Please Select file \n to delete");

This will show the alert like

Please select file 
to delete.

With the magic of user-defined literals, we have yet another solution to this. C++14 added a std::string literal operator.

using namespace std::string_literals;
auto const x = "\0" "0"s;

Constructs a string of length 2, with a '\0' character (null) followed by a '0' character (the digit zero). I am not sure if it is more or less clear than the initializer_list<char> constructor approach, but it at least gets rid of the ' and , characters.

Another option could be using bootstrap select. On their own words:

A custom select / multiselect for Bootstrap using button dropdown, designed to behave like regular Bootstrap selects.

I have this grid class that can be used as a simple matrix if you don't need any mathematical operators.

Your question is pretty hard to decode, but I'll try taking a stab at it.

You say:

I want to create a json object having two fields uniqueIDofSelect and optionValue in javascript.

And then you say:

I need output like

[{"selectID":2,"optionValue":"2"},
{"selectID":4,"optionvalue":"1"}]

Well, this example output doesn't have the field named uniqueIDofSelect, it only has optionValue.

Anyway, you are asking for array of objects...

Then in the comment to michaels answer you say:

It creates json object array. but I need only one json object.

So you don't want an array of objects?

What do you want then?

Please make up your mind.

Sorry, didn't quite get your question. So something like this?

str.ToCharArray().Any(char.IsDigit);

Or does the value have to be an integer completely, without any additional strings?

if(str.ToCharArray().All(char.IsDigit(c));

One construct, I once stumbled upon looked like

Class<T> persistentClass = (Class<T>)
   ((ParameterizedType)getClass().getGenericSuperclass())
      .getActualTypeArguments()[0];

So there seems to be some reflection-magic around that I unfortunetly don't fully understand... Sorry.

For those who are looking for PHP ( >5.3.5 ) PDO statement, we can set charset as per below:

$dbh = new PDO('mysql:host=localhost;dbname=testdb;charset=utf8', 'username', 'password');

In my case

-Djava.awt.headless=true

was set (indirectly by a Maven configuration). I had to actively use

-Djava.awt.headless=false

to override this.

1. Right click the folder, click on Properties.
2. Click on the Security tab
3. Add the name Everyone to the user list.

You may face two errors while testing tomcat server startup.

1. Error in the Eclipse inbuilt browser - This page can’t be displayed Turn on TLS 1.0, TLS 1.1, and TLS 1.2 in Advanced settings and try connecting to https://localhost:8080 again. If this error persists, it is possible that this site uses an unsupported protocol. Please contact the site administrator.
2. 404 error in the normal browsers.

Fixes -

1. For the eclipse browser error, check whether you are using secured URL - https://localhost:8080. This should be http://localhost:8080
2. For the 404 error: Go to Tomcat server in the console. Do a right click, select properties. In the properties window, Click "Switch location" and then click OK. Followed by that, Go to Tomcat server in the console, double click it, Under "server locations" select "Use Tomcat installation" radio button. Save it.

The reason for choosing this option is, When the default option is given as eclipse location, we will see 404 error as it changes Catalina parameters (sometimes). But if we change it to Tomcat location, it works fine.

For-loops:

For-loop in C:

for(int x = 0; x<=3; x++)
{
    //Do something!
}

The same loop in 8086 assembler:

        xor cx,cx   ; cx-register is the counter, set to 0
loop1   nop         ; Whatever you wanna do goes here, should not change cx
        inc cx      ; Increment
        cmp cx,3    ; Compare cx to the limit
        jle loop1   ; Loop while less or equal

That is the loop if you need to access your index (cx). If you just wanna to something 0-3=4 times but you do not need the index, this would be easier:

        mov cx,4    ; 4 iterations
loop1   nop         ; Whatever you wanna do goes here, should not change cx
        loop loop1  ; loop instruction decrements cx and jumps to label if not 0

If you just want to perform a very simple instruction a constant amount of times, you could also use an assembler-directive which will just hardcore that instruction

times 4 nop

Do-while-loops

Do-while-loop in C:

int x=1;
do{
    //Do something!
}
while(x==1)

The same loop in assembler:

        mov ax,1
loop1   nop         ; Whatever you wanna do goes here
        cmp ax,1    ; Check wether cx is 1
        je loop1    ; And loop if equal

While-loops

While-loop in C:

while(x==1){
    //Do something
}

The same loop in assembler:

        jmp loop1   ; Jump to condition first
cloop1  nop         ; Execute the content of the loop
loop1   cmp ax,1    ; Check the condition
        je cloop1   ; Jump to content of the loop if met

For the for-loops you should take the cx-register because it is pretty much standard. For the other loop conditions you can take a register of your liking. Of course replace the no-operation instruction with all the instructions you wanna perform in the loop.

Inside your current folder, simply press Shift+Alt+F --then--> Enter.

The prompt will appear with your current folder's path set.

Note: That works only in Windows 7 / Vista. What it does is that drops the "File" menu down for you, because the "Shift" key is pressed the option "Open command window here" is enabled and focused as the first available option of "File" menu. Pressing enter starts the focused option therefor the command window.

Edit:

In case you are in a folder and you already selected some of its contents (file/folder) this wont work. In that case Click on the empty area inside the folder to deselect any previously selected files and repeat.

Edit2:

Another way you can open terminal in current directory is to type cmd on file browser navigation bar where the path of current folder is written.

In order to focus with your keyboard on the navigation bar Ctrl+L. Then you can type cmd and hit Enter

Here's a method that worked for me. When you type into the field, it puts that text into the hidden span, then gets its new width and applies it to the input field. It grows and shrinks with your input, with a safeguard against the input virtually disappearing when you erase all input. Tested in Chrome. (EDIT: works in Safari, Firefox and Edge at the time of this edit)

I struggled a bit with the answers on this question and didn't have much luck with the answers in a similar SO post either. So this is what worked for me - bearing in mind that in my case, the submodule was maintained by a different team, so the conflict came from different submodule versions in master and my local branch of the project I was working on:

1. Run git status - make a note of the submodule folder with conflicts

2. Reset the submodule to the version that was last committed in the current branch:

   git reset HEAD path/to/submodule

3. At this point, you have a conflict-free version of your submodule which you can now update to the latest version in the submodule's repository:

   cd path/to/submodule
   git submodule foreach git pull origin SUBMODULE-BRANCH-NAME

4. And now you can commit that and get back to work.

If you don't want to use dangerouslySetInnerHTML then you can use the below mentioned solution

var Iframe = React.createClass({     
  render: function() {
    return(         
      <div>          
        <iframe src={this.props.src} height={this.props.height} width={this.props.width}/>         
      </div>
    )
  }
});

ReactDOM.render(
  <Iframe src="http://plnkr.co/" height="500" width="500"/>,
  document.getElementById('example')
);

All these work:

#include <iostream>
using namespace std;

//Good, because manual memory management isn't needed and this uses
//less heap memory (or no heap memory) so this is safer if
//used in a low memory situation
void f() { throw string("foo"); }

//Valid, but avoid manual memory management if there's no reason to use it
void g() { throw new string("foo"); }

//Best.  Just a pointer to a string literal, so no allocation is needed,
//saving on cleanup, and removing a chance for an allocation to fail.
void h() { throw "foo"; }

int main() {
  try { f(); } catch (string s) { cout << s << endl; }
  try { g(); } catch (string* s) { cout << *s << endl; delete s; }
  try { h(); } catch (const char* s) { cout << s << endl; }
  return 0;
}

You should prefer h to f to g. Note that in the least preferable option you need to free the memory explicitly.

i was trying trying to GRANT read-only privileges to a particular table to a user called walters-ro. So when i ran the sql command # GRANT SELECT ON table_name TO walters-ro; --- i got the following error..`syntax error at or near “-”

The solution to this was basically putting the user_name into double quotes since there is a dash(-) between the name.

# GRANT SELECT ON table_name TO "walters-ro";

That solved the problem.

1. Open Run in your system.

2. Type %windir%\System32\cliconfg.exe

3. Click on ok button then check that the "TCP/IP Network Protocol Default Value Setup" pop-up is open.

4. Highlight TCP/IP under the Enabled protocols window.

5. Click the Properties button.

6. Enter the new port number, then click OK.

The internal keyword is heavily used when you are building a wrapper over non-managed code.

When you have a C/C++ based library that you want to DllImport you can import these functions as static functions of a class, and make they internal, so your user only have access to your wrapper and not the original API so it can't mess with anything. The functions being static you can use they everywhere in the assembly, for the multiple wrapper classes you need.

You can take a look at Mono.Cairo, it's a wrapper around cairo library that uses this approach.

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

Start with a tab delimited file:

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

create a sequence file

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

try to load; as expected, this will fail:

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

But with this table:

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

The load works just fine:

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

Now load into the sequence table from the text table:

insert into table test_sq select * from test_t;

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

In the Latest version of Laravel i.e above Laravel 5.0. It is quite simple to perform this task. In Model, inside the class just write 'use SoftDeletes'. Example

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\SoftDeletes;

class User extends Model
{
    use SoftDeletes;
}

And In Controller, you can do deletion. Example

User::where('email', '[email protected]')->delete();

or

User::where('email', '[email protected]')->softDeletes();

Make sure that you must have 'deleted_at' column in the users Table.

put it your input field

ref={(el) => this.myInput = el}

If you need something quick, datetime_object.date() gives you a date of a datetime object.

I created a github repository after creating my local git repository so I needed to accept the changes into local before pushing to github. In this case the only change was the readme file created as optional step when creating github repository.

git pull https://github.com/*username*/*repository*.git master

repository URL is got from here on project github page :

I then re-initialised (this may not be needed)

git init
git add .
git commit -m "update"

Then push :

git push

public static String removeExtension(String file) {
    if(file != null && file.length() > 0) {
        while(file.contains(".")) {
            file = file.substring(0, file.lastIndexOf('.'));
        }
    }
    return file;
}

Put a global variable to generate the ids.

<script>
    $(function(){
        // Variable to get ids for the checkboxes
        var idCounter=1;
        $("#btn1").click(function(){
            var val = $("#txtAdd").val();
            $("#divContainer").append ( "<label for='chk_" + idCounter + "'>" + val + "</label><input id='chk_" + idCounter + "' type='checkbox' value='" + val + "' />" );
            idCounter ++;
        });
    });
</script>

Here's how i conditionally applied gray text style on a disabled button

import { Component } from '@angular/core';

@Component({
  selector: 'my-app',
  styleUrls: [ './app.component.css' ],
  template: `
  <button 
    (click)='buttonClick1()' 
    [disabled] = "btnDisabled"
    [ngStyle]="{'color': (btnDisabled)? 'gray': 'black'}">
    {{btnText}}
  </button>`
})
export class AppComponent  {
  name = 'Angular';
  btnText = 'Click me';
  btnDisabled = false;
  buttonClick1() {
    this.btnDisabled = true;
    this.btnText = 'you clicked me';
    setTimeout(() => {
      this.btnText = 'click me again';
      this.btnDisabled = false
      }, 5000);
  }
}

Here's a working example:
https://stackblitz.com/edit/example-conditional-disable-button?file=src%2Fapp%2Fapp.component.html

The above solutions didn't work for me. But I found this that worked:

Install Grunt in node_modules rather than globally

Unable to find local Grunt likely means that you have installed Grunt globally.

The Grunt CLI insists that you install grunt in your local node_modules directory, so Grunt is local to your project.

This will fail:

npm install -g grunt

Do this instead:

npm install grunt --save-dev

Set a cookie value on the page, and then read it back server side.

You won't be able to set a specific header, but the value will be accessible in the headers section and not the content body.

It sounds like you just want a copy of the source code. If so why not just copy the directory and exclude the .git directory from the copy?

just replace this line

bm = BitmapFactory.decodeResource(null, R.id.image);

with

Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.YourImageName);

I mean to say just change null value with getResources() If you use this code in any button or Image view click event just append getApplicationContext() before getResources()..

TASK:

Let's consider the following example:

if (!answer.isSuccessful()) {
    result = "wrong"
} else {
    result = answer.body().string()
}
return result

We need the following equivalent in Kotlin:

return ( !answer.isSuccessful() ) ? "wrong" : answer.body().string()

SOLUTION 1.a. You can use if-expression in Kotlin:

return if (!answer.isSuccessful()) "wrong" else answer.body().string()

SOLUTION 1.b. It can be much better if you flip this if-expression (let's do it without not):

return if (answer.isSuccessful()) answer.body().string() else "wrong"

SOLUTION 2. Kotlin’s Elvis operator ?: can do a job even better:

return answer.body()?.string() ?: "wrong"

SOLUTION 3. Or use an Extension function for the corresponding Answer class:

fun Answer.bodyOrNull(): Body? = if (isSuccessful()) body() else null

SOLUTION 4. Using the Extension function you can reduce a code thanks to Elvis operator:

return answer.bodyOrNull()?.string() ?: "wrong"

SOLUTION 5. Or just use when operator:

when (!answer.isSuccessful()) {
    parseInt(str) -> result = "wrong"
    else -> result = answer.body().string()
}

Post data to backend using retrofit

It normally represents a parameter to be supplied by client.

Sometimes you need to see version of mongodb after making a connection from your project/application/code. In this case you can follow like this:

 mongoose.connect(
    encodeURI(DB_URL), {
      keepAlive: true
    },
    (err) => {
      if (err) {
        console.log(err)
      }else{
           const con = new mongoose.mongo.Admin(mongoose.connection.db)
              con.buildInfo( (err, db) => {
              if(err){
                throw err
              }
             // see the db version
             console.log(db.version)
            })
      }
    }
  )

Hope this will be helpful for someone.

I was driving myself crazy with this exact problem. My JSON Marshaller and Unmarshaller were not populating my Go struct. Then I found the solution at https://eager.io/blog/go-and-json:

"As with all structs in Go, it’s important to remember that only fields with a capital first letter are visible to external programs like the JSON Marshaller."

After that, my Marshaller and Unmarshaller worked perfectly!

For Android 4.2 (API 17), you need to use android:configChanges="locale|layoutDirection" in your AndroidManifest.xml. See onConfigurationchanged is not called over jellybean(4.2.1)

Generics solution to covert any List<Type> to String []:

public static  <T> String[] listToArray(List<T> list) {
    String [] array = new String[list.size()];
    for (int i = 0; i < array.length; i++)
        array[i] = list.get(i).toString();
    return array;
}

Note You must override toString() method.

class Car {
  private String name;
  public Car(String name) {
    this.name = name;
  }
  public String toString() {
    return name;
  }
}
final List<Car> carList = new ArrayList<Car>();
carList.add(new Car("BMW"))
carList.add(new Car("Mercedes"))
carList.add(new Car("Skoda"))
final String[] carArray = listToArray(carList);

I found that I needed 3 interface definitions in order to handle various version of android.

public void openFileChooser(ValueCallback < Uri > uploadMsg) {
  mUploadMessage = uploadMsg;
  Intent i = new Intent(Intent.ACTION_GET_CONTENT);
  i.addCategory(Intent.CATEGORY_OPENABLE);
  i.setType("image/*");
  FreeHealthTrack.this.startActivityForResult(Intent.createChooser(i, "Image Chooser"), FILECHOOSER_RESULTCODE);
}

public void openFileChooser(ValueCallback < Uri > uploadMsg, String acceptType) {
  openFileChooser(uploadMsg);
}

public void openFileChooser(ValueCallback < Uri > uploadMsg, String acceptType, String capture) {
  openFileChooser(uploadMsg);
}

 if (e.attr("name") == "firstName" ) {
     $("#firstName__validate").text($(error).text());
     console.log($(error).html());
 }

Try this get text of error object

Use this:

android:singleLine="true"

def post(self,request):
        serializer = ProductSerializer(data=request.DATA, files=request.FILES)
        if serializer.is_valid():
            serializer.save()
            return Response(serializer.data)

What you can do is set specific width and height to your iframe (for example these could be equal to your window dimensions) and then applying a scale transformation to it. The scale value will be the ratio between your window width and the dimension you wanted to set to your iframe.

E.g.

<iframe width="1024" height="768" src="http://www.bbc.com" style="-webkit-transform:scale(0.5);-moz-transform-scale(0.5);"></iframe>

Get your object's constructor function and then inspect its name property.

myObj.constructor.name

Returns "myClass".

Since HTTP Params class is immutable therefore you need to chain the set method:

const params = new HttpParams()
.set('aaa', '111')
.set('bbb', "222");

I found that for me using a normal if and for loop statement worked perfectly.

for i in $(cat file2);do if [ $(grep -i $i file1) ];then echo "$i found" >>Matching_lines.txt;else echo "$i missing" >>missing_lines.txt ;fi;done

I was having authentication problems running pg_dump, so I moved my dump file

mv database_dump /tmp

into the temp directory and then ran

su -u postgres
cd /tmp
pg_restore database_dump

If you have a large database dump, you may just want to create another directory where your current user and the postgres user can access and putting the database dump file into that.

When converting datetime to integers one must keep in mind the tens, hundreds and thousands.... like "2018-11-03" must be like 20181103 in int for that you have to 2018*10000 + 100* 11 + 3

Similarly another example, "2018-11-03 10:02:05" must be like 20181103100205 in int

Explanatory Code

dt = datetime(2018,11,3,10,2,5)
print (dt)

#print (dt.timestamp()) # unix representation ... not useful when converting to int

print (dt.strftime("%Y-%m-%d"))
print (dt.year*10000 + dt.month* 100  + dt.day)
print (int(dt.strftime("%Y%m%d")))

print (dt.strftime("%Y-%m-%d %H:%M:%S"))
print (dt.year*10000000000 + dt.month* 100000000 +dt.day * 1000000 + dt.hour*10000  +  dt.minute*100 + dt.second)
print (int(dt.strftime("%Y%m%d%H%M%S")))

General Function

To avoid that doing manually use below function

def datetime_to_int(dt):
    return int(dt.strftime("%Y%m%d%H%M%S"))

If you want to prefer a simple AWK approach, here Is my take:

docker rm -f $(docker ps | awk '{ if($2 == "<your image name>") { print $NF}}')

$(docker ps | awk '{ if($2 == "<your image name>") { print $NF}}') - prints the docker container names based on input image

docker ps - list all containers

awk '{ if($2 == "<your-image-name>") { print $NF}}' - The second parsed column of docker ps gives the image name. Comparing it with your image name will execute print $NF which prints the container name.

docker rm -f removes the containers

For example, removing all running containers of ubuntu image, can be done simply as:

docker rm -f $(docker ps | awk '{ if($2 == "ubuntu:latest") { print $NF}}')

PS: Remember to include the image tag in AWK, since it's a equal comparator.

Another solution (non T-SQL): you can use tablediff utility. For example if you want to compare two tables (Localitate) from two different servers (ROBUH01 & ROBUH02) you can use this shell command:

C:\Program Files\Microsoft SQL Server\100\COM>tablediff -sourceserver ROBUH01 -s
ourcedatabase SIM01 -sourceschema dbo -sourcetable Localitate -destinationserver
 ROBUH02 -destinationschema dbo -destinationdatabase SIM02 -destinationtable Lo

I have struggled with this same problem (Ubuntu 16.04, Bluefish editor, FireFox, Google Chrome.

Solution: Clear browsing data in Chrome "Settings > Advanced Settings > Clear Browsing Data", In Firefox, "Open Menu image top right tool bar 'Preferences' > Advanced ", look for this image in the menu: Cached Web Content click the button "Clear Now". Browser's cache the .css file and if it has not changed they usually won't reload it. So when you change your .css file clear this web cache and it should work unless a problem exists in your .css file. Peace, Stan

Maybe you'd like to check if the previous point of history is within your app. For example, if you enter directly to your app and do location.back() (by pressing a <- back button in a toolbar for example), you'd be back to your browser's main page, instead of going somewhere else within your app.

This is how I check for this:

import { Component } from '@angular/core';
import { ActivatedRoute, Router } from '@angular/router';
import { Location } from '@angular/common';

@Component({
  selector: 'app-foo',
  template: ''
})
export class FooComponent {

  private readonly canGoBack: boolean;

  constructor(
    private readonly route: ActivatedRoute,
    private readonly router: Router,
    private readonly location: Location
  ) {
    // This is where the check is done. Make sure to do this
    // here in the constructor, otherwise `getCurrentNavigation()`
    // will return null. 
    this.canGoBack = !!(this.router.getCurrentNavigation()?.previousNavigation);
  }

  goBack(): void {
    if (this.canGoBack) {
      // We can safely go back to the previous location as
      // we know it's within our app.
      this.location.back();
    } else {
      // There's no previous navigation.
      // Here we decide where to go. For example, let's say the
      // upper level is the index page, so we go up one level.
      this.router.navigate(['..'], {relativeTo: this.route});
    }
  }

}

We check if the navigation that loaded the current route has a previous sibling. This has to be done in the constructor, while the navigation process is still active.

This doesn't come without caveats though:

• canGoBack will be false even if the previous location is actually within our app but the page was refreshed.
• The user might want to "go back" to the previous page (where the goBack() ocurred) by clicking the browser's back button, but since the app went back on history instead of pushing a new location, the user will be going back even further and might get confused.

In my case; it was available in the anaconda folder in "All App" from main menu

Had issues using the code in the answer provided by @haynar above (wouldn't play on Chrome), and it seems that one of the more modern ways to ensure it plays is to use the video tag

Example:

<video controls="controls" width="800" height="600" 
       name="Video Name" src="http://www.myserver.com/myvideo.mov"></video>

This worked like a champ for my .mov file (generated from Keynote) in both Safari and Chrome, and is listed as supported in most modern browsers (The video tag is supported in Internet Explorer 9+, Firefox, Opera, Chrome, and Safari.)

Note: Will work in IE / etc.. if you use MP4 (Mov is not officially supported by those guys)

Yes. Try the following in your python interpreter:

and

>>>False and 3/0
False
>>>True and 3/0
ZeroDivisionError: integer division or modulo by zero

or

>>>True or 3/0
True
>>>False or 3/0
ZeroDivisionError: integer division or modulo by zero

I found this the quick and easy way: Used: org.json.XML class from java-json.jar

if (statusCode == 200 && inputStream != null) {
    BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream, "UTF-8"));
    StringBuilder responseStrBuilder = new StringBuilder();

    String inputStr;
    while ((inputStr = bufferedReader.readLine()) != null) {
        responseStrBuilder.append(inputStr);
    }

    jsonObject = XML.toJSONObject(responseStrBuilder.toString());
}

Focus on one specific thing. Disk I/O is slow, so I'd take that out of the test if all you are going to tweak is the database query.

And if you need to time your database execution, look for database tools instead, like asking for the query plan, and note that performance varies not only with the exact query and what indexes you have, but also with the data load (how much data you have stored).

That said, you can simply put your code in a function and run that function with timeit.timeit():

def function_to_repeat():
    # ...

duration = timeit.timeit(function_to_repeat, number=1000)

This would disable the garbage collection, repeatedly call the function_to_repeat() function, and time the total duration of those calls using timeit.default_timer(), which is the most accurate available clock for your specific platform.

You should move setup code out of the repeated function; for example, you should connect to the database first, then time only the queries. Use the setup argument to either import or create those dependencies, and pass them into your function:

def function_to_repeat(var1, var2):
    # ...

duration = timeit.timeit(
    'function_to_repeat(var1, var2)',
    'from __main__ import function_to_repeat, var1, var2', 
    number=1000)

would grab the globals function_to_repeat, var1 and var2 from your script and pass those to the function each repetition.

You can give like this....

I need to point out here that you're incorrectly adding middleware to the application. The app.use calls should not be done within the app.get request handler, but outside of it. Simply call them directly after createServer, or take a look at the other examples in the docs.

The secret you pass to express.session should be a string constant, or perhaps something taken from a configuration file. Don't feed it something the client might know, that's actually dangerous. It's a secret only the server should know about.

If you want to store the email address in the session, simply do something along the lines of:

req.session.email = req.param('email');

With that out of the way...

If I understand correctly, what you're trying to do is handle one or more HTTP requests and keep track of a session, then later on open a Socket.IO connection from which you need the session data as well.

What's tricky about this problem is that Socket.IO's means of making the magic work on any http.Server is by hijacking the request event. Thus, Express' (or rather Connect's) session middleware is never called on the Socket.IO connection.

I believe you can make this work, though, with some trickery.

You can get to Connect's session data; you simply need to get a reference to the session store. The easiest way to do that is to create the store yourself before calling express.session:

// A MemoryStore is the default, but you probably want something
// more robust for production use.
var store = new express.session.MemoryStore;
app.use(express.session({ secret: 'whatever', store: store }));

Every session store has a get(sid, callback) method. The sid parameter, or session ID, is stored in a cookie on the client. The default name of that cookie is connect.sid. (But you can give it any name by specifying a key option in your express.session call.)

Then, you need to access that cookie on the Socket.IO connection. Unfortunately, Socket.IO doesn't seem to give you access to the http.ServerRequest. A simple work around would be to fetch the cookie in the browser, and send it over the Socket.IO connection.

Code on the server would then look something like the following:

var io      = require('socket.io'),
    express = require('express');

var app    = express.createServer(),
    socket = io.listen(app),
    store  = new express.session.MemoryStore;
app.use(express.cookieParser());
app.use(express.session({ secret: 'something', store: store }));

app.get('/', function(req, res) {
  var old = req.session.email;
  req.session.email = req.param('email');

  res.header('Content-Type', 'text/plain');
  res.send("Email was '" + old + "', now is '" + req.session.email + "'.");
});

socket.on('connection', function(client) {
  // We declare that the first message contains the SID.
  // This is where we handle the first message.
  client.once('message', function(sid) {
    store.get(sid, function(err, session) {
      if (err || !session) {
        // Do some error handling, bail.
        return;
      }

      // Any messages following are your chat messages.
      client.on('message', function(message) {
        if (message.email === session.email) {
          socket.broadcast(message.text);
        }
      });
    });
  });
});

app.listen(4000);

This assumes you only want to read an existing session. You cannot actually create or delete sessions, because Socket.IO connections may not have a HTTP response to send the Set-Cookie header in (think WebSockets).

If you want to edit sessions, that may work with some session stores. A CookieStore wouldn't work for example, because it also needs to send a Set-Cookie header, which it can't. But for other stores, you could try calling the set(sid, data, callback) method and see what happens.

Just wrap your option in $(option) to make it act the way you want it to. You can also make the code shorter by doing

$('#span_id > select > option[value="input your i here"]').attr("selected", "selected")

You can use the SpringBoot plugin:

plugins {
  id "org.springframework.boot" version "2.2.2.RELEASE"
}

Create the jar

gradle assemble

And then run it

java -jar build/libs/*.jar

Note: your project does NOT need to be a SpringBoot project to use this plugin.

You can pass data as the third argument to call(). Or, depending on your API, it's possible you may want to use the sixth parameter.

From the docs:

$this->call($method, $uri, $parameters, $files, $server, $content);

Try this:

String numberStr = "3.5";
Float number = null;
try {
   number = Float.parseFloat(numberStr);
} catch (NumberFormatException e) {
    System.out.println("numberStr is not a number");
}

No, they are not always.

It depends on whether you allow user input to be placed within the query itself. For example:

$dbh = new PDO("blahblah");

$tableToUse = $_GET['userTable'];

$stmt = $dbh->prepare('SELECT * FROM ' . $tableToUse . ' where username = :username');
$stmt->execute( array(':username' => $_REQUEST['username']) );

would be vulnerable to SQL injections and using prepared statements in this example won't work, because the user input is used as an identifier, not as data. The right answer here would be to use some sort of filtering/validation like:

$dbh = new PDO("blahblah");

$tableToUse = $_GET['userTable'];
$allowedTables = array('users','admins','moderators');
if (!in_array($tableToUse,$allowedTables))    
 $tableToUse = 'users';

$stmt = $dbh->prepare('SELECT * FROM ' . $tableToUse . ' where username = :username');
$stmt->execute( array(':username' => $_REQUEST['username']) );

Note: you can't use PDO to bind data that goes outside of DDL (Data Definition Language), i.e. this does not work:

$stmt = $dbh->prepare('SELECT * FROM foo ORDER BY :userSuppliedData');

The reason why the above does not work is because DESC and ASC are not data. PDO can only escape for data. Secondly, you can't even put ' quotes around it. The only way to allow user chosen sorting is to manually filter and check that it's either DESC or ASC.

Take away the spaces. So do:

matches <- unique(grep("A1|A9|A6", myfile$Letter, value=TRUE, fixed=TRUE))

The profiler data is written to a collection in your DB, not to file. See http://docs.mongodb.org/manual/tutorial/manage-the-database-profiler/

I would recommend using 10gen's MMS service, and feed development profiler data there, where you can filter and sort it in the UI.

This just works on React & React Native

const data = require('./data/photos.json');

console.log('[-- typeof data --]', typeof data); // object


const fotos = data.xs.map(item => {
    return { uri: item };
});

You can like:

window.open('url', 'window name', 'window settings')

jQuery:

$('a#link_id').click(function(){
  window.open('url', 'window name', 'window settings');
  return false;
});

You could also set the target to _blank actually.

Funny, I was just researching this yesterday!

I personally use Monaco 10 or 11 for the Mac, but a good cross platform font would have to be Droid Sans Mono: http://damieng.com/blog/2007/11/14/droid-sans-mono-great-coding-font Or DejaVu sans mono is another great one (goes under a lot of different names, will be Menlo on SNow leopard and is really just a repackaged Prima/Vera) check it out here: Prima/Vera... Check it out here: http://dejavu-fonts.org/wiki/index.php?title=Download

I'd recommend using std::vector: something like

typedef std::vector<int> A;
typedef std::vector<A> AS;

There's nothing wrong with the slight overkill of STL, and you'll be able to spend more time implementing the specific features of your app instead of reinventing the bicycle.

In C++17 this is called structured bindings, which allows for the following:

std::map< foo, bar > testing = { /*...blah...*/ };
for ( const auto& [ k, v ] : testing )
{
  std::cout << k << "=" << v << "\n";
}

I have been hasseling with that as other folks have.

I used the criteria;

=countif(matchingList,C2)=0

where matchingList is the list that i am using as a filter.

have a look at this

http://www.youtube.com/watch?v=x47VFMhRLnM&list=PL63A7644FE57C97F4&index=30

The trick i found is that normally you would have the column heading in the criteria matching the data column heading. this will not work for criteria that is a formula.

What I found was if I left the column heading blank for only the criteria that has the countif formula in the advanced filter works. If I have the column heading i.e. the column heading for column C2 in my formula example then the filter return no output.

Hope this helps

Image:

1. List images

   docker images

2. Remove one image

   docker rmi image_name

3. Force remove one image

   docker rmi -f image_name

Container:

1. List all containers

   docker ps -a

2. Remove one container

   docker rm container_id

3. Force remove one container

   docker rm -f container_id

You can't do this directly, but a little code fiddling makes it possible to emulate.

function foo($blah, $x = false, $y = false) {
  if (!$x) $x = "some value";
  if (!$y) $y = "some other value";

  // code
}

In my case I was developing an ASP.Net MVC5 web app and the certificate errors on my local dev machine (IISExpress certificate) started becoming a practical concern once I started working with service workers. Chrome simply wouldn't register my service worker because of the certificate error.

I did, however, notice that during my automated Selenium browser tests, Chrome seem to just "ignore" all these kinds of problems (e.g. the warning page about an insecure site), so I asked myself the question: How is Selenium starting Chrome for running its tests, and might it also solve the service worker problem?

Using Process Explorer on Windows, I was able to find out the command-line arguments with which Selenium is starting Chrome:

"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --disable-background-networking --disable-client-side-phishing-detection --disable-default-apps --disable-hang-monitor --disable-popup-blocking --disable-prompt-on-repost --disable-sync --disable-web-resources --enable-automation --enable-logging --force-fieldtrials=SiteIsolationExtensions/Control --ignore-certificate-errors --log-level=0 --metrics-recording-only --no-first-run --password-store=basic --remote-debugging-port=12207 --safebrowsing-disable-auto-update --test-type=webdriver --use-mock-keychain --user-data-dir="C:\Users\Sam\AppData\Local\Temp\some-non-existent-directory" data:,

There are a bunch of parameters here that I didn't end up doing necessity-testing for, but if I run Chrome this way, my service worker registers and works as expected.

The only one that does seem to make a difference is the --user-data-dir parameter, which to make things work can be set to a non-existent directory (things won't work if you don't provide the parameter).

Hope that helps someone else with a similar problem. I'm using Chrome 60.0.3112.90.

Let's say you have a shiny Foo class. Well you have 3 options:

1) You want to use the method (or attribute) of a class inside the definition of that class:

class Foo(object):
    attribute1 = 1                   # class attribute (those don't use 'self' in declaration)
    def __init__(self):
        self.attribute2 = 2          # instance attribute (those are accessible via first
                                     # parameter of the method, usually called 'self'
                                     # which will contain nothing but the instance itself)
    def set_attribute3(self, value): 
        self.attribute3 = value

    def sum_1and2(self):
        return self.attribute1 + self.attribute2

2) You want to use the method (or attribute) of a class outside the definition of that class

def get_legendary_attribute1():
    return Foo.attribute1

def get_legendary_attribute2():
    return Foo.attribute2

def get_legendary_attribute1_from(cls):
    return cls.attribute1

get_legendary_attribute1()           # >>> 1
get_legendary_attribute2()           # >>> AttributeError: type object 'Foo' has no attribute 'attribute2'
get_legendary_attribute1_from(Foo)   # >>> 1

3) You want to use the method (or attribute) of an instantiated class:

f = Foo()
f.attribute1                         # >>> 1
f.attribute2                         # >>> 2
f.attribute3                         # >>> AttributeError: 'Foo' object has no attribute 'attribute3'
f.set_attribute3(3)
f.attribute3                         # >>> 3

    Intent in = new Intent(getApplicationContext(),SecondaryScreen.class);    
    startActivity(in);

    This is an explicit intent to start secondscreen activity.

Thanks HansUp for your answer, it is very helpful and it works!

I found three patterns working in Access, yours is the best, because it works in all cases.

• INNER JOIN, your variant. I will call it "closed set pattern". It is possible to join more than two tables to the same table with good performance only with this pattern.

  SELECT C_Name, cr.P_FirstName+" "+cr.P_SurName AS ClassRepresentativ, cr2.P_FirstName+" "+cr2.P_SurName AS ClassRepresentativ2nd
  FROM
       ((class
         INNER JOIN person AS cr 
         ON class.C_P_ClassRep=cr.P_Nr
       )
       INNER JOIN person AS cr2
       ON class.C_P_ClassRep2nd=cr2.P_Nr
    )
  

  ;

• INNER JOIN "chained-set pattern"

  SELECT C_Name, cr.P_FirstName+" "+cr.P_SurName AS ClassRepresentativ, cr2.P_FirstName+" "+cr2.P_SurName AS ClassRepresentativ2nd
  FROM person AS cr
  INNER JOIN ( class 
     INNER JOIN ( person AS cr2
     ) ON class.C_P_ClassRep2nd=cr2.P_Nr
  ) ON class.C_P_ClassRep=cr.P_Nr
  ;
  

• CROSS JOIN with WHERE

  SELECT C_Name, cr.P_FirstName+" "+cr.P_SurName AS ClassRepresentativ, cr2.P_FirstName+" "+cr2.P_SurName AS ClassRepresentativ2nd
  FROM class, person AS cr, person AS cr2
  WHERE class.C_P_ClassRep=cr.P_Nr AND class.C_P_ClassRep2nd=cr2.P_Nr
  ;
  

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

    setTheme(R.style.Theme_AppCompat_Light_NoActionBar);
    requestWindowFeature(Window.FEATURE_NO_TITLE);

    this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN
    , WindowManager.LayoutParams.FLAG_FULLSCREEN);

    setContentView(R.layout.activity__splash_screen);
}

Here's how I did it:

var leftKey = 37, upKey = 38, rightKey = 39, downKey = 40;
var keystate;
document.addEventListener("keydown", function (e) {
    keystate[e.keyCode] = true;
});
document.addEventListener("keyup", function (e) {
    delete keystate[e.keyCode];
});

if (keystate[leftKey]) {
//code to be executed when left arrow key is pushed.
}
if (keystate[upKey]) {
//code to be executed when up arrow key is pushed.
}
if (keystate[rightKey]) {
//code to be executed when right arrow key is pushed.
}
if (keystate[downKey]) {
//code to be executed when down arrow key is pushed.
}

This has become very easy with Jackson 2.0 and the Joda module.

ObjectMapper mapper = new ObjectMapper();
mapper.registerModule(new JodaModule());

And if you are looking for changes only among certain file(s), then:

git diff branch1 branch2 -- myfile1.js myfile2.js

branch1 is optional and your current branch (the branch you are on) will be considered by default if branch1 is not provided. e.g:

git diff master -- controller/index.js

Use the built-in isinstance() function.

import pandas as pd

def f(var):
    if isinstance(var, pd.DataFrame):
        print("do stuff")

Use the following to evaluate an expression (constant 0 evaluates to false).

#if 0
 ...
#endif

As far as rm -f doing "anything else", it does force (-f is shorthand for --force) silent removal in situations where rm would otherwise ask you for confirmation. For example, when trying to remove a file not writable by you from a directory that is writable by you.

Demo: http://jsfiddle.net/sunnycpp/u4vjR/2/

Here I have created handle-destroy directive.

ctrl.directive('handleDestroy', function() {
    return function(scope, tElement, attributes) {        
        scope.$on('$destroy', function() {
            alert("In destroy of:" + scope.todo.text);
        });
    };
});

"-P" is the right option, please read on for more related information:

wget -nd -np -P /dest/dir --recursive http://url/dir1/dir2

Relevant snippets from man pages for convenience:

   -P prefix
   --directory-prefix=prefix
       Set directory prefix to prefix.  The directory prefix is the directory where all other files and subdirectories will be saved to, i.e. the top of the retrieval tree.  The default is . (the current directory).

   -nd
   --no-directories
       Do not create a hierarchy of directories when retrieving recursively.  With this option turned on, all files will get saved to the current directory, without clobbering (if a name shows up more than once, the
       filenames will get extensions .n).


   -np
   --no-parent
       Do not ever ascend to the parent directory when retrieving recursively.  This is a useful option, since it guarantees that only the files below a certain hierarchy will be downloaded.

All links to the Azure Active Directory Connection page now seem to be invalid.

I had an older version of Azure AD installed too, this is what worked for me. Install this.

Run these in an elevated PS session:

uninstall-module AzureAD  # this may or may not be needed
install-module AzureAD
install-module AzureADPreview
install-module MSOnline

I was then able to log in and run what I needed.

Product Version may be preferred if you're using versioning via GitVersion or other versioning software.

To get this from within your class library you can call System.Diagnostics.FileVersionInfo.ProductVersion:

using System.Diagnostics;
using System.Reflection;

//...

var assemblyLocation = Assembly.GetExecutingAssembly().Location;
var productVersion = FileVersionInfo.GetVersionInfo(assemblyLocation).ProductVersion

You could also use the RenderView Controller extension from here (source)

and use it like this:

public ActionResult Do() {
var html = this.RenderView("index", theModel);
...
}

it works for razor and web-forms viewengines

I wrote telegram bot, and have some problem with update rows. Use this example, if you have Model

def update_state(chat_id, state):
    try:
        value = Users.query.filter(Users.chat_id == str(chat_id)).first()
        value.state = str(state)
        db.session.flush()
        db.session.commit()
        #db.session.close()
    except:
        print('Error in def update_state')

Why use db.session.flush()? That's why >>> SQLAlchemy: What's the difference between flush() and commit()?

Updating to 2012, when we see that image sizes, and number of images, are growing and growing, in all applications...

We need some distinction between "original image" and "processed image", like thumbnail.

As Jcoby's answer says, there are two options, then, I recommend:

• use blob (Binary Large OBject): for original image store, at your table. See Ivan's answer (no problem with backing up blobs!), PostgreSQL additional supplied modules, How-tos etc.

• use a separate database with DBlink: for original image store, at another (unified/specialized) database. In this case, I prefer bytea, but blob is near the same. Separating database is the best way for a "unified image webservice".

• use bytea (BYTE Array): for caching thumbnail images. Cache the little images to send it fast to the web-browser (to avoiding rendering problems) and reduce server processing. Cache also essential metadata, like width and height. Database caching is the easiest way, but check your needs and server configs (ex. Apache modules): store thumbnails at file system may be better, compare performances. Remember that it is a (unified) web-service, then can be stored at a separate database (with no backups), serving many tables. See also PostgreSQL binary data types manual, tests with bytea column, etc.

NOTE1: today the use of "dual solutions" (database+filesystem) is deprecated (!). There are many advantages to using "only database" instead dual. PostgreSQL have comparable performance and good tools for export/import/input/output.

NOTE2: remember that PostgreSQL have only bytea, not have a default Oracle's BLOB: "The SQL standard defines (...) BLOB. The input format is different from bytea, but the provided functions and operators are mostly the same",Manual.

EDIT 2014: I have not changed the original text above today (my answer was Apr 22 '12, now with 14 votes), I am opening the answer for your changes (see "Wiki mode", you can edit!), for proofreading and for updates.

If you want to implement a singleton, that is a class that runs in your program with only one instance in memory throughout the execution of the application, then one of the ways to implement a singleton is to nest a private static class inside a public class. Then the inner private class only instantiates itself when its public method to access the private instance is called.

Check out this wiki article,

https://en.wikipedia.org/wiki/Singleton_pattern

The concept takes a while to chew on.

If are you working with numbers a lot, you might want to take a look at NumPy. It lets you perform all kinds of operation directly on numerical arrays. For example:

>>> import numpy
>>> array = numpy.array([49, 51, 53, 56])
>>> array - 13
array([36, 38, 40, 43])

This one is like the answer above which uses the MySql DATE_FORMAT() function. I also selected just one specific week in Jan.

SELECT 
    DatePart(day, DateAdded) AS date, 
    COUNT(entryhash) AS count 
FROM Responses 
    where DateAdded > '2020-01-25' and DateAdded < '2020-02-01' 
GROUP BY 
    DatePart(day, DateAdded )

You can use regular expressions. Use Matcher and Pattern methods to get the desired output

Depending on how complicated your regular expression is, you could possibly just use simple string slicing. I'm not sure about the practicality of this for your application or whether or not it would actually offer any speed improvements.

'testsentence'['stsen']
=> 'stsen' # evaluates to true
'testsentence'['koala']
=> nil # evaluates to false
