Programs & Examples On #Nested query

This code will dynamically generate the expression for you with the nested clauses. I have a scenario where the number of "OR" s was unknown, so I'm using the below. Usage:

        private static void Main(string[] args)
        {
            var query = new PropertyString(@"<Query><Where>{{WhereClauses}}</Where></Query>");
            var whereClause =
                new PropertyString(@"<Eq><FieldRef Name='ID'/><Value Type='Counter'>{{NestClauseValue}}</Value></Eq>");
            var andClause = new PropertyString("<Or>{{FirstExpression}}{{SecondExpression}}</Or>");

            string[] values = {"1", "2", "3", "4", "5", "6"};

            query["WhereClauses"] = NestEq(whereClause, andClause, values);

            Console.WriteLine(query);
        }

And here's the code:

   private static string MakeExpression(PropertyString nestClause, string value)
        {
            var expr = nestClause.New();
            expr["NestClauseValue"] = value;
            return expr.ToString();
        }

        /// <summary>
        /// Recursively nests the clause with the nesting expression, until nestClauseValue is empty.
        /// </summary>
        /// <param name="whereClause"> A property string in the following format: <Eq><FieldRef Name='Title'/><Value Type='Text'>{{NestClauseValue}}</Value></Eq>"; </param>
        /// <param name="nestingExpression"> A property string in the following format: <And>{{FirstExpression}}{{SecondExpression}}</And> </param>
        /// <param name="nestClauseValues">A string value which NestClauseValue will be filled in with.</param>
        public static string NestEq(PropertyString whereClause, PropertyString nestingExpression, string[] nestClauseValues, int pos=0)
        {
            if (pos > nestClauseValues.Length)
            {
                return "";
            }

            if (nestClauseValues.Length == 1)
            {
                return MakeExpression(whereClause, nestClauseValues[0]);
            }

            var expr = nestingExpression.New();
            if (pos == nestClauseValues.Length - 2)
            {
                expr["FirstExpression"] = MakeExpression(whereClause, nestClauseValues[pos]);
                expr["SecondExpression"] = MakeExpression(whereClause, nestClauseValues[pos + 1]);
                return expr.ToString();
            }
            else
            {
                expr["FirstExpression"] = MakeExpression(whereClause, nestClauseValues[pos]);
                expr["SecondExpression"] = NestEq(whereClause, nestingExpression, nestClauseValues, pos + 1);
                return expr.ToString();
            }
        }






          public class PropertyString
    {
        private string _propStr;

        public PropertyString New()
        {
            return new PropertyString(_propStr );
        }

        public PropertyString(string propStr)
        {
            _propStr = propStr;
            _properties = new Dictionary<string, string>();
        }

        private Dictionary<string, string> _properties;
        public string this[string key]
        {
            get
            {
                return _properties.ContainsKey(key) ? _properties[key] : string.Empty;
            }
            set
            {
                if (_properties.ContainsKey(key))
                {
                    _properties[key] = value;
                }
                else
                {
                    _properties.Add(key, value);
                }
            }
        }

        /// Replaces properties in the format {{propertyName}} in the source string with values from KeyValuePairPropertiesDictionarysupplied dictionary.nce you've set a property it's replaced in the string and you

        /// <param name="keyValuePairPropertiesDictionary"></param>
        /// <returns></returns>
        public override string ToString()
        {
            string modifiedStr = _propStr;
            foreach (var keyvaluePair in _properties)
            {
                modifiedStr = modifiedStr.Replace("{{" + keyvaluePair.Key + "}}", keyvaluePair.Value);
            }

            return modifiedStr;
        }
    }

I wrote a more general helper class which accepts a string-based dictionary of custom parameters, so that they can be set by the caller without having to hard-code them. It goes without saying that you should only use such method when you want (or need) to manually issue a SOAP-based web service: in most common scenarios the recommended approach would be using the Web Service WSDL together with the Add Service Reference Visual Studio feature instead.

Very good post on merging with conflicts - GitGuys: Merging With a Conflict - Conflicts And Resolutions

The blog is really great - illustrative, clean examples and understandable. Definitely worth checking out.

As Jake points out, TARGET_IPHONE_SIMULATOR is a subset of TARGET_OS_IPHONE.

Also, TARGET_OS_IPHONE is a subset of TARGET_OS_MAC.

So a better approach might be:

#ifdef _WIN64
   //define something for Windows (64-bit)
#elif _WIN32
   //define something for Windows (32-bit)
#elif __APPLE__
    #include "TargetConditionals.h"
    #if TARGET_OS_IPHONE && TARGET_IPHONE_SIMULATOR
        // define something for simulator   
    #elif TARGET_OS_IPHONE
        // define something for iphone  
    #else
        #define TARGET_OS_OSX 1
        // define something for OSX
    #endif
#elif __linux
    // linux
#elif __unix // all unices not caught above
    // Unix
#elif __posix
    // POSIX
#endif

First, try with sudo, as the current user may not have access permissions to communicate to docker daemon i.e. /var/run/docker.sock

If its still not working, then, after the installation, simply stop the docker daemon as,

$ sudo service docker stop

And, run the following command to start the daemon in background,

$ sudo nohup docker daemon -H tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock

To make working with Docker easier, you should add your username to the Docker users group. Adding a user to the group can be done with the command below

$ sudo usermod -aG docker $USER

Also, this step is mention at official documentation of docker Post-installation steps for Linux (https://docs.docker.com/engine/installation/linux/linux-postinstall/)

The Ubuntu 16.04 users can follow these steps,

Inside file /lib/systemd/system/docker.service change: ExecStart=/usr/bin/dockerd fd:// with ExecStart=/usr/bin/dockerd -H tcp://0.0.0.0:2375

Inside file /etc/init.d/docker change:

DOCKER_OPTS= with DOCKER_OPTS="-H ****tcp://0.0.0.0:2375 "

and then restart your machine. And, start playing with docker.

To push a single tag:

git push origin <tag_name>

And the following command should push all tags (not recommended):

git push --tags

To do links, you can do

.social h2 a:link {
  color: pink;
  font-size: 14px;   
}

You can change the hover, visited, and active link styling too. Just replace "link" with what you want to style. You can learn more at the w3schools page CSS Links.

The most common approach is to either lowercase or uppercase the search string and the data. But there are two problems with that.

1. It works in English, but not in all languages. (Maybe not even in most languages.) Not every lowercase letter has a corresponding uppercase letter; not every uppercase letter has a corresponding lowercase letter.
2. Using functions like lower() and upper() will give you a sequential scan. It can't use indexes. On my test system, using lower() takes about 2000 times longer than a query that can use an index. (Test data has a little over 100k rows.)

There are at least three less frequently used solutions that might be more effective.

1. Use the citext module, which mostly mimics the behavior of a case-insensitive data type. Having loaded that module, you can create a case-insensitive index by CREATE INDEX ON groups (name::citext);. (But see below.)
2. Use a case-insensitive collation. This is set when you initialize a database. Using a case-insensitive collation means you can accept just about any format from client code, and you'll still return useful results. (It also means you can't do case-sensitive queries. Duh.)
3. Create a functional index. Create a lowercase index by using CREATE INDEX ON groups (LOWER(name));. Having done that, you can take advantage of the index with queries like SELECT id FROM groups WHERE LOWER(name) = LOWER('ADMINISTRATOR');, or SELECT id FROM groups WHERE LOWER(name) = 'administrator'; You have to remember to use LOWER(), though.

The citext module doesn't provide a true case-insensitive data type. Instead, it behaves as if each string were lowercased. That is, it behaves as if you had called lower() on each string, as in number 3 above. The advantage is that programmers don't have to remember to lowercase strings. But you need to read the sections "String Comparison Behavior" and "Limitations" in the docs before you decide to use citext.

The %#08X conversion must precede the value with 0X; that is required by the standard. There's no evidence in the standard that the # should alter the behaviour of the 08 part of the specification except that the 0X prefix is counted as part of the length (so you might want/need to use %#010X. If, like me, you like your hex presented as 0x1234CDEF, then you have to use 0x%08X to achieve the desired result. You could use %#.8X and that should also insert the leading zeroes.

Try variations on the following code:

#include <stdio.h>

int main(void)
{
    int j = 0;
    printf("0x%.8X = %#08X = %#.8X = %#010x\n", j, j, j, j);
    for (int i = 0; i < 8; i++)
    {
        j = (j << 4) | (i + 6);
        printf("0x%.8X = %#08X = %#.8X = %#010x\n", j, j, j, j);
    }
    return(0);
}

On an RHEL 5 machine, and also on Mac OS X (10.7.5), the output was:

0x00000000 = 00000000 = 00000000 = 0000000000
0x00000006 = 0X000006 = 0X00000006 = 0x00000006
0x00000067 = 0X000067 = 0X00000067 = 0x00000067
0x00000678 = 0X000678 = 0X00000678 = 0x00000678
0x00006789 = 0X006789 = 0X00006789 = 0x00006789
0x0006789A = 0X06789A = 0X0006789A = 0x0006789a
0x006789AB = 0X6789AB = 0X006789AB = 0x006789ab
0x06789ABC = 0X6789ABC = 0X06789ABC = 0x06789abc
0x6789ABCD = 0X6789ABCD = 0X6789ABCD = 0x6789abcd

I'm a little surprised at the treatment of 0; I'm not clear why the 0X prefix is omitted, but with two separate systems doing it, it must be standard. It confirms my prejudices against the # option.

The treatment of zero is according to the standard.

ISO/IEC 9899:2011 §7.21.6.1 The fprintf function

¶6 The flag characters and their meanings are:
...
# The result is converted to an "alternative form". ... For x (or X) conversion, a nonzero result has 0x (or 0X) prefixed to it. ...

(Emphasis added.)

Note that using %#X will use upper-case letters for the hex digits and 0X as the prefix; using %#x will use lower-case letters for the hex digits and 0x as the prefix. If you prefer 0x as the prefix and upper-case letters, you have to code the 0x separately: 0x%X. Other format modifiers can be added as needed, of course.

For printing addresses, use the <inttypes.h> header and the uintptr_t type and the PRIXPTR format macro:

#include <inttypes.h>
#include <stdio.h>

int main(void)
{
    void *address = &address;  // &address has type void ** but it converts to void *
    printf("Address 0x%.12" PRIXPTR "\n", (uintptr_t)address);
    return 0;
}

Example output:

Address 0x7FFEE5B29428

Choose your poison on the length — I find that a precision of 12 works well for addresses on a Mac running macOS. Combined with the . to specify the minimum precision (digits), it formats addresses reliably. If you set the precision to 16, the extra 4 digits are always 0 in my experience on the Mac, but there's certainly a case to be made for using 16 instead of 12 in portable 64-bit code (but you'd use 8 for 32-bit code).

I would always use sp_executesql these days, all it really is is a wrapper for EXEC which handles parameters & variables.

However do not forget about OPTION RECOMPILE when tuning queries on very large databases, especially where you have data spanned over more than one database and are using a CONSTRAINT to limit index scans.

Unless you use OPTION RECOMPILE, SQL server will attempt to create a "one size fits all" execution plan for your query, and will run a full index scan each time it is run.

This is much less efficient than a seek, and means it is potentially scanning entire indexes which are constrained to ranges which you are not even querying :@

let is functional as its essentially a Proc. Also its cached.

One gotcha I found right away with let... In a Spec block that is evaluating a change.

let(:object) {FactoryGirl.create :object}

expect {
  post :destroy, id: review.id
}.to change(Object, :count).by(-1)

You'll need to be sure to call let outside of your expect block. i.e. you're calling FactoryGirl.create in your let block. I usually do this by verifying the object is persisted.

object.persisted?.should eq true

Otherwise when the let block is called the first time a change in the database will actually happen due to the lazy instantiation.

Update

Just adding a note. Be careful playing code golf or in this case rspec golf with this answer.

In this case, I just have to call some method to which the object responds. So I invoke the _.persisted?_ method on the object as its truthy. All I'm trying to do is instantiate the object. You could call empty? or nil? too. The point isn't the test but bringing the object ot life by calling it.

So you can't refactor

object.persisted?.should eq true

to be

object.should be_persisted 

as the object hasn't been instantiated... its lazy. :)

Update 2

leverage the let! syntax for instant object creation, which should avoid this issue altogether. Note though it will defeat a lot of the purpose of the laziness of the non banged let.

Also in some instances you might actually want to leverage the subject syntax instead of let as it may give you additional options.

subject(:object) {FactoryGirl.create :object}

The invalid hostname indicates that the actual site you configured in the IIS Express configuration file is (most likely) not running. IIS Express doesn't have a process model like IIS does.

For your site to run it would need to be started explicitly (either by opening and accessing from webmatrix, or from command line calling iisexpress.exe (from it's installation directory) with the /site parameter.

In general, the steps to allow fully qualified DNS names to be used for local access are Let's use your example of the DNS name dev.example.com

1. edit %windows%\system32\drivers\etc\hosts file to map dev.example.com to 127.0.0.1 (admin privilege required). If you control DNS server (like in Nick's case) then the DNS entry is sufficient as this step is not needed.
2. If you access internet through proxy, make sure the dev.example.com will not be forwared to proxy (you have to put in on the exception list in your browser (for IE it would be Tools/Internet Options/Connections/Lan Settings, then go to Proxy Server/Advanced and put dev.example.com on the exeption list.

3. Configure IIS Express binding for your site (eg:Site1) to include dev.example.com. Administrative privilege will be needed to use the binding. Alternatively, a one-time URL reservation can be made with http.sys using

   netsh http add urlacl url=http://dev.example.com:<port>/ user=<user_name>

4. start iisexpress /site:Site1 or open Site1 in WebMatrix

HTML:

<div class="foo">
    /* whatever is required */
</div>

CSS:

.foo {
    top: 0;
    transition: top ease 0.5s;
}

.foo:hover{
    top: -10px;
}

This is just a basic transition to ease the div tag up by 10px when it is hovered on. The transition property's values can be edited along with the class.hover properties to determine how the transition works.

Following is the solution I wrote up for performance reasons:

void hex2bin(const char* in, size_t len, unsigned char* out) {

  static const unsigned char TBL[] = {
     0,   1,   2,   3,   4,   5,   6,   7,   8,   9,  58,  59,  60,  61,
    62,  63,  64,  10,  11,  12,  13,  14,  15,  71,  72,  73,  74,  75,
    76,  77,  78,  79,  80,  81,  82,  83,  84,  85,  86,  87,  88,  89,
    90,  91,  92,  93,  94,  95,  96,  10,  11,  12,  13,  14,  15
  };

  static const unsigned char *LOOKUP = TBL - 48;

  const char* end = in + len;

  while(in < end) *(out++) = LOOKUP[*(in++)] << 4 | LOOKUP[*(in++)];

}

Example:

unsigned char seckey[32];

hex2bin("351aaaec0070d13d350afae2bc43b68c7e590268889869dde489f2f7988f3fee", 64, seckey);

/*
  seckey = {
     53,  26, 170, 236,   0, 112, 209,  61,  53,  10, 250, 226, 188,  67, 182, 140, 
    126,  89,   2, 104, 136, 152, 105, 221, 228, 137, 242, 247, 152, 143,  63, 238
  };
*/

If you don't need to support lowercase:

static const unsigned char TBL[] = {
     0,   1,   2,   3,   4,   5,   6,   7,   8,   9,  58,  59,
    60,  61,  62,  63,  64,  10,  11,  12,  13,  14,  15
};

Use an empty element sized for the content as the background, and position the content over the blurred element.

#dialog_base{
  background:white;
  background:rgba(255,255,255,0.8);

  position: absolute;
  top: 40%;
  left: 50%;
  z-index: 50;
  margin-left: -200px;
  height: 200px;
  width: 400px;

  filter:blur(4px);
  -o-filter:blur(4px);
  -ms-filter:blur(4px);
  -moz-filter:blur(4px);
  -webkit-filter:blur(4px);
}

#dialog_content{
  background: transparent;
  position: absolute;
  top: 40%;
  left: 50%;
  margin-left -200px;
  overflow: hidden;
  z-index: 51;
}

The background element can be inside of the content element, but not the other way around.

<div id='dialog_base'></div>
<div id='dialog_content'>
    Some Content
    <!-- Alternatively with z-index: <div id='dialog_base'></div> -->
</div>

This is not easy if the content is not always consistently sized, but it works.

There is a way that might be a little bit longer, but it works fine. This is a method to sort an int array descendingly.

Hope that this will help someone ,,, some day:

public static int[] sortArray (int[] array) {
    int [] sortedArray = new int[array.length];
    for (int i = 0; i < sortedArray.length; i++) {
        sortedArray[i] = array[i];
    }
    
    boolean flag = true;
    int temp;
    while (flag) {
        flag = false;
        for (int i = 0; i < sortedArray.length - 1; i++) {
            if(sortedArray[i] < sortedArray[i+1]) {
                temp = sortedArray[i];
                sortedArray[i] = sortedArray[i+1];
                sortedArray[i+1] = temp;
                flag = true;
            }
        }
    }
    
    return sortedArray;
    
}

perhaps, you can first determine if the DOM does really exists,

function walkmydog() {
    //when the user starts entering
    var dom = document.getElementById('WallSearch');
    if(dom == null){
        alert('sorry, WallSearch DOM cannot be found');
        return false;    
    }

    if(dom.value.length == 0){
        alert("nothing");
    }
}

if (document.addEventListener){
    document.addEventListener("DOMContentLoaded", walkmydog, false);
}

In my case, HTTPS protocol was not supported by libcurl at the first place. To find out which protocols are supported and which are not, I checked the curl version using command:

curl --version

It provided information as follows: curl 7.50.3 (x86_64-apple-darwin15.6.0) libcurl/7.50.3 SecureTransport zlib/1.2.5 Protocols: dict file ftp ftps gopher http imap imaps ldap ldaps pop3 pop3s rtsp smb smbs smtp smtps telnet tftp Features: IPv6 Largefile NTLM NTLM_WB SSL libz UnixSockets

where https protocol happens to be not supported.

Then I re-installed curl and installed it using the following commands(after unpacked):

./configure --with-darwinssl (enable ssl communication in mac) make make test sudo make install

And after several minutes of work, Problems resolved!

Then I re-run the curl version command, it showed:

curl 7.50.3 (x86_64-apple-darwin15.6.0) libcurl/7.50.3 SecureTransport zlib/1.2.5 Protocols: dict file ftp ftps gopher http https imap imaps ldap ldaps pop3 pop3s rtsp smb smbs smtp smtps telnet tftp Features: IPv6 Largefile NTLM NTLM_WB SSL libz UnixSockets

HTTPS protocol showed up!

Finally, a useful site to refer when you run into curl problems. https://curl.haxx.se/docs/install.html

For <input type=number>, by the HTML5 CR, the size attribute is not allowed. However, in Obsolete features it says: “Authors should not, but may despite requirements to the contrary elsewhere in this specification, specify the maxlength and size attributes on input elements whose type attributes are in the Number state. One valid reason for using these attributes regardless is to help legacy user agents that do not support input elements with type="number" to still render the text field with a useful width.”

Thus, the size attribute can be used, but it only affects older browsers that do not support type=number, so that the element falls back to a simple text control, <input type=text>.

The rationale behind this is that the browser is expected to provide a user interface that takes the other attributes into account, for good usability. As the implementations may vary, any size imposed by an author might mess things up. (This also applies to setting the width of the control in CSS.)

The conclusion is that you should use <input type=number> in a more or less fluid setup that does not make any assumptions about the dimensions of the element.

Perl solutions:

quick and dirty:

perl -lpe 'print "Project_Name=sowstest" if $. == 8' file

• -l strips newlines and adds them back in, eliminating the need for "\n"
  
• -p loops over the input file, printing every line
  
• -e executes the code in single quotes
  

$. is the line number

equivalent to @glenn's awk solution, using named arguments:

perl -slpe 'print $s if $. == $n' -- -n=8 -s="Project_Name=sowstest" file

• -s enables a rudimentary argument parser
  
• -- prevents -n and -s from being parsed by the standard perl argument parser
  

positional command arguments:

perl -lpe 'BEGIN{$n=shift; $s=shift}; print $s if $. == $n' 8 "Project_Name=sowstest" file

environment variables:

setenv n 8 ; setenv s "Project_Name=sowstest"
echo $n ; echo $s
perl -slpe 'print $ENV{s} if $. == $ENV{n}' file

ENV is the hash which contains all environment variables

Getopt to parse arguments into hash %o:

perl -MGetopt::Std -lpe 'BEGIN{getopt("ns",\%o)}; print $o{s} if $. == $o{n}' -- -n 8 -s "Project_Name=sowstest" file

Getopt::Long and longer option names

perl -MGetopt::Long -lpe 'BEGIN{GetOptions(\%o,"line=i","string=s")}; print $o{string} if $. == $o{line}' -- --line 8 --string "Project_Name=sowstest" file

Getopt is the recommended standard-library solution.
This may be overkill for one-line perl scripts, but it can be done

try this code

DataRow foundRow = FinalDt.Rows.Find(Value);

but set at lease one primary key

Being able to quickly see all the methods that can be overriden from a super class. For example when extending UITableViewController I just type in my implementation:

- ta

and then I hit ESC to see all the methods from my superclass that begin with "ta" such as

- (UITableViewCell *) tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

This also works when adopting protocols.

Go to Project | Properties and then Assembly Information and then Assembly Version and put an * in the last or the second-to-last box (you can't auto-increment the Major or Minor components).

There are two obvious points, as well as the points in the other answer:

• They are exactly equivalent when using sub queries:

  SELECT * FROM table
  WHERE column IN(subquery);
  
  SELECT * FROM table
  WHERE column = ANY(subquery);
  

On the other hand:

• Only the IN operator allows a simple list:

  SELECT * FROM table
  WHERE column IN(… , … , …);
  

Presuming they are exactly the same has caught me out several times when forgetting that ANY doesn’t work with lists.

You'll probably have to either give it a constant class and call getElementsByClassName, or maybe just use getElementsByTagName, and loop through your results, checking the name.

I'd suggest looking at your underlying problem and figure out a way where you can know the ID in advance.

Maybe if you posted a little more about why you're getting this, we could find a better alternative.

you could use is_displayed() like below

res = driver.find_element_by_id("some_id").is_displayed()
assert res, 'element not displayed!'

I just went to the file system and deleted the file directly, then continued with git checkout and it worked.

I've had the problem occur several times and it may be related to developers doing delete, push, re-add, push or some such thing.

I tried as below.

I called ng-click to angularjs controller on Encourage button,

               <tr ng-cloak
                  ng-repeat="user in result.users">
                   <td>{{user.userName}}</rd>
                   <td>
                      <a class="btn btn-primary span11" ng-click="setUsername({{user.userName}})" href="#encouragementModal" data-toggle="modal">
                            Encourage
                       </a>
                  </td>
                </tr>

I set userName of encouragementModal from angularjs controller.

    /**
     * Encouragement controller for AngularJS
     * 
     * @param $scope
     * @param $http
     * @param encouragementService
     */
    function EncouragementController($scope, $http, encouragementService) {
      /**
       * set invoice number
       */
      $scope.setUsername = function (username) {
            $scope.userName = username;
      };
     }
    EncouragementController.$inject = [ '$scope', '$http', 'encouragementService' ];

I provided a place(userName) to get value from angularjs controller on encouragementModal.

<div id="encouragementModal" class="modal hide fade">
  <div class="modal-header">
    <button type="button" class="close" data-dismiss="modal"
      aria-hidden="true">&times;</button>
    <h3>Confirm encouragement?</h3>
  </div>
  <div class="modal-body">
      Do you really want to encourage <b>{{userName}}</b>?
  </div>
  <div class="modal-footer">
    <button class="btn btn-info"
      ng-click="encourage('${createLink(uri: '/encourage/')}',{{userName}})">
      Confirm
    </button>
    <button class="btn" data-dismiss="modal" aria-hidden="true">Never Mind</button>
  </div>
</div>

It worked and I saluted myself.

The following should work:

pip install pywin32

But it didn't for me. I fixed this by downloading and installing the exe from here:

https://github.com/mhammond/pywin32/releases

tableColumns

• null for all columns as in SELECT * FROM ...
• new String[] { "column1", "column2", ... } for specific columns as in SELECT column1, column2 FROM ... - you can also put complex expressions here:
  new String[] { "(SELECT max(column1) FROM table1) AS max" } would give you a column named max holding the max value of column1

whereClause

• the part you put after WHERE without that keyword, e.g. "column1 > 5"
• should include ? for things that are dynamic, e.g. "column1=?" -> see whereArgs

whereArgs

• specify the content that fills each ? in whereClause in the order they appear

the others

• just like whereClause the statement after the keyword or null if you don't use it.

Example

String[] tableColumns = new String[] {
    "column1",
    "(SELECT max(column1) FROM table2) AS max"
};
String whereClause = "column1 = ? OR column1 = ?";
String[] whereArgs = new String[] {
    "value1",
    "value2"
};
String orderBy = "column1";
Cursor c = sqLiteDatabase.query("table1", tableColumns, whereClause, whereArgs,
        null, null, orderBy);

// since we have a named column we can do
int idx = c.getColumnIndex("max");

is equivalent to the following raw query

String queryString =
    "SELECT column1, (SELECT max(column1) FROM table1) AS max FROM table1 " +
    "WHERE column1 = ? OR column1 = ? ORDER BY column1";
sqLiteDatabase.rawQuery(queryString, whereArgs);

By using the Where/Bind -Args version you get automatically escaped values and you don't have to worry if input-data contains '.

Unsafe: String whereClause = "column1='" + value + "'";
Safe: String whereClause = "column1=?";

because if value contains a ' your statement either breaks and you get exceptions or does unintended things, for example value = "XYZ'; DROP TABLE table1;--" might even drop your table since the statement would become two statements and a comment:

SELECT * FROM table1 where column1='XYZ'; DROP TABLE table1;--'

using the args version XYZ'; DROP TABLE table1;-- would be escaped to 'XYZ''; DROP TABLE table1;--' and would only be treated as a value. Even if the ' is not intended to do bad things it is still quite common that people have it in their names or use it in texts, filenames, passwords etc. So always use the args version. (It is okay to build int and other primitives directly into whereClause though)

Lo-Dash, now a superset of Underscore.js, has a couple of deep clone functions:

• _.cloneDeep(object)

• _.cloneDeepWith(object, (val) => {if(_.isElement(val)) return val.cloneNode(true)})

  the second parameter is a function that is invoked to produce the cloned value.

From an answer of the author himself:

lodash underscore build is provided to ensure compatibility with the latest stable version of Underscore.

OK, maybe there are more like me that do not have any UVESA_MODE or S3 references in their menu.lst. First, do "VBoxManage setextradata "VM_NAME_HERE" "CustomVideoMode1" "320x480x32"" procedure through terminal. My custom videomode was "1920x1089x32"... (sorry, I use Linux, so procedure works on linux) for Windows, just add .exe to VBoxManage.. Look in the first entry as described before, this is the menu entry you would normally boot. I normally use nano as it works more easy for me. And nano happens to be present in Android >6 too. (other version not tried)

Procedure:

• Boot VM, chose the "debug mode" option to boot. Pressing "enter" after a while will result in the prompt
• Change directory to /mnt/grub "cd /mnt/grub"
• list directory content with "ls" (not necessary but I like to see where I am)
• copy menu.lst (make this standard procedure before changing anything) "cp menu.lst menu.lst.bak" (or whatever extension you like to use for backup)
• open menu.lst, e.g.: "nano menu.lst".
• look in first menu entry (normally there are 4, starting with the titles you see in the boot menu) the "kernel" entry, which ends with the word "quiet"
• replace "quiet" with something like "vga=ask" if you would like to be asked every time at boot for the screen resolution, or "vga=(HEX value)" as seen in surlac's anwer.
• exit and save, don't forget to actually save it! double check this. (ctrl+X, YES, Enter for nano)
• reboot VM with "YOUR HOST KEY" + "R" (normally "right control" + "R")

Hope this helps anyone as it did solve my problem.

edit: I see that I did place this article in the wrong place, since the original question is about another Android version. Does anyone know how to move it to an appropriate location?

I think you are misinterpreting the source of the error; rExternalTotal appears to be equal to a single cell. rReportData.offset(0,0) is equal to rReportData
rReportData.offset(261,0).end(xlUp) is likely also equal to rReportData, as you offset by 261 rows and then use the .end(xlUp) function which selects the top of a contiguous data range.
If you are interested in the sum of just a column, you can just refer to the whole column:

dExternalTotal = Application.WorksheetFunction.Sum(columns("A:A"))

or

dExternalTotal = Application.WorksheetFunction.Sum(columns((rReportData.column))

The worksheet function sum will correctly ignore blank spaces.

Let me know if this helps!

Best I have ever used:

apt-cyg package manager

When merging topic branch "B" in "A" using git merge, I get some conflicts. I >know all the conflicts can be solved using the version in "B".

I am aware of git merge -s ours. But what I want is something like git merge >-s their.

I'm assuming that you created a branch off of master and now want to merge back into master, overriding any of the old stuff in master. That's exactly what I wanted to do when I came across this post.

Do exactly what it is you want to do, Except merge the one branch into the other first. I just did this, and it worked great.

git checkout Branch
git merge master -s ours

Then, checkout master and merge your branch in it (it will go smoothly now):

git checkout master
git merge Branch

From my little date difference calculator:

var startDate = new Date(2000, 1-1, 1);  // 2000-01-01
var endDate =   new Date();              // Today

// Calculate the difference of two dates in total days
function diffDays(d1, d2)
{
  var ndays;
  var tv1 = d1.valueOf();  // msec since 1970
  var tv2 = d2.valueOf();

  ndays = (tv2 - tv1) / 1000 / 86400;
  ndays = Math.round(ndays - 0.5);
  return ndays;
}

So you would call:

var nDays = diffDays(startDate, endDate);

(Full source at http://david.tribble.com/src/javascript/jstimespan.html.)

Addendum

The code can be improved by changing these lines:

  var tv1 = d1.getTime();  // msec since 1970
  var tv2 = d2.getTime();

I solved the problem with PIP in Windows using "Fiddler" (https://www.telerik.com/download/fiddler). After downloading and installing, do the following:

"Rules" => click "Automatically Authenticate"

Example: pip install virtualenv -proxy 127.0.0.1:8888

Just open your prompt and use.

https://github.com/pypa/pip/issues/1182 Search for "voltagex" (commented on 22 May 2015)

var table = $('#myTableId').DataTable();
var a= [];
$.each(table.rows('.myClassName').data(), function() {
a.push(this["productId"]);
});

console.log(a[0]);

Your string is wider than your format width of 2. So there's no padding to be done.

The accepted answer works for me.

Also, in MSSQLMS, you can browse the tree in the Object Explorer to the table you want to query.

[Server] -> Server Objects -> Linked Servers -> [Linked server] -> Catalogs -> [Database] -> [table]

then Right click, Script Table as, SELECT To, New Query Window

And the query will be generated for you with the right FROM, which you can use in your JOIN

The size of the pointer may be something different than that of int. Also an implementation could produce better than simple hex value representation of the address when you use %p.

to get total seconds

var i = TimeSpan.FromTicks(startDate.Ticks).TotalSeconds;

and to get datetime from seconds

var thatDateTime = new DateTime().AddSeconds(i)

(char)myint;

for example:

Console.WriteLine("(char)122 is {0}", (char)122);

yields:

(char)122 is z

I came here because I had the same problem.
What was the problem for me was that the procedure was defined in the package body, but not in the package header.
I was executing my function with a lose BEGIN END statement.

According to documentation: to verify host or peer certificate you need to specify alternate certificates with the CURLOPT_CAINFO option or a certificate directory can be specified with the CURLOPT_CAPATH option.

Also look at CURLOPT_SSL_VERIFYHOST:

• 1 to check the existence of a common name in the SSL peer certificate.
• 2 to check the existence of a common name and also verify that it matches the hostname provided.

curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);

Remove the values then check (remove null check here if you want)

const x = A.filter(item => item !== undefined || item !== null).length

With Lodash

const x = _.size(_.filter(A, item => !_.isNil(item)))

You want to do

svn merge -r [revision to revert from]:[revision to revert to] [path/filename]

Once you do that, you will have that revision of the file in a committable state. Commit the file.

df['col'] = 'str' + df['col'].astype(str)

Example:

>>> df = pd.DataFrame({'col':['a',0]})
>>> df
  col
0   a
1   0
>>> df['col'] = 'str' + df['col'].astype(str)
>>> df
    col
0  stra
1  str0

Programmatically in Swift 5 with Xcode 10.2

Building on top of @La masse's solution, but using autolayout to support rotation

Set anchors for the view's position (left, top, centerY, centerX, etc). You can also set the width anchor or set the frame.width dynamically with the UIScreen extension provided (to support rotation)

label = UILabel()
label.numberOfLines = 0
label.lineBreakMode = .byWordWrapping
self.view.addSubview(label)
// SET AUTOLAYOUT ANCHORS
label.translatesAutoresizingMaskIntoConstraints = false
label.leftAnchor.constraint(equalTo: self.view.leftAnchor, constant: 20).isActive = true
label.rightAnchor.constraint(equalTo: self.view.rightAnchor, constant: -20).isActive = true
label.topAnchor.constraint(equalTo: self.view.topAnchor, constant: 20).isActive = true
// OPTIONALLY, YOU CAN USE THIS INSTEAD OF THE WIDTH ANCHOR (OR LEFT/RIGHT)
// label.frame.size = CGSize(width: UIScreen.absoluteWidth() - 40.0, height: 0)
label.text = "YOUR LONG TEXT GOES HERE"
label.sizeToFit()

If setting frame.width dynamically using UIScreen:

extension UIScreen {   // OPTIONAL IF USING A DYNAMIC FRAME WIDTH
    class func absoluteWidth() -> CGFloat {
        var width: CGFloat
        if UIScreen.main.bounds.width > UIScreen.main.bounds.height {
            width = self.main.bounds.height // Landscape
        } else {
            width = self.main.bounds.width // Portrait
        }
        return width
    }
}

If your input file has a fixed amount of columns separated by commas and you know in which columns are the strings it might be best to use the function

textscan()

Note that you can specify a format where you read up to a maximum number of characters in the string or until a delimiter (comma) is found.

I'm writing a script to run cmd-line scripts. ( Because in some cases, there just is no viable substitute for a Linux command -- such as the case of rsync. )

What I really wanted was to use the default python logging mechanism in every case where it was possible to do so, but to still capture any error when something went wrong that was unanticipated.

This code seems to do the trick. It may not be particularly elegant or efficient ( although it doesn't use string+=string, so at least it doesn't have that particular potential bottle- neck ). I'm posting it in case it gives someone else any useful ideas.

Obviously, if you're not as subject to whimsy as I am, replace LOG_IDENTIFIER with another string that you're not like to ever see someone write to a log.

Favicons only work when served from a web-server which sets mime-types correctly for served content. Loading from a local file might not work in chromium. Loading from an incorrectly configured web-server will not work.

Web-servers such as lighthttpd must be configured manually to set the mime type correctly.

Because of the likelihood that mimetype assignment will not work in all environments, I would suggest you use an inline base64 encoded ico file instead. This will load faster as well, as it reduces the number of http requests sent to the server.

On POSIX based systems you can base64 encode a file with the base64 command.

To create a base64 encoded ico line use the command:

$ base64 favicon.ico --wrap 0

And insert the output into the line:

<link href="data:image/x-icon;base64,HERE" rel="icon" type="image/x-icon" />

Replacing the word HERE like so:

<link href="data:image/x-icon;base64,AAABAAEAEBAQAAEABAAoAQAAFgAAACgAAAAQAAAAIAAAAAEABAAAAAAAgAAAAAAAAAAAAAAAEAAAAAAAAAAAAAAA////AERpOgA5cCcA7vDtAF6jSABllFcAuuCvAK2trQAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAFjMzMzMzNxARYzMzMzVBEEERYzMzNhERZxRGMzZxQEA2FER3cRSAgTNxgEEREIQBMzFIARERFEEzNhERARFAATMzYREBEAhBMzMzEYEBFEEzMzNhEQQRQDMzMzcRgEAAMzMzNhERgIEzMzMyERgEQDMzMzMRAEgEMzMzMxERAEEAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA" rel="icon" type="image/x-icon" />

This is based on CMS's answer. The question asked for the timer to be restarted on the blur and stopped on the focus, so I moved it around a little:

$(function () {
  var timerId = 0;

  $('textarea').focus(function () {
    clearInterval(timerId);
  });

  $('textarea').blur(function () {
    timerId = setInterval(function () {
     //some code here 
    }, 1000);
  });
});

I have been using Inno Setup for an installer. I'm using 64-bit Windows 7 only. I'm finding that registry entries are being written to

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall

I haven't yet figured out how to get this list to be reported by WMI (although the program is listed as installed in Programs and Features). If I figure it out, I'll try to remember to report back here.

UPDATE:

Entries for 32-bit programs installed on a 64-bit machine go in that registry location. There's more written here:

http://mdb-blog.blogspot.com/2010/09/c-check-if-programapplication-is.html

See my comment that describes 32-bit vs 64-bit behavior in that same post here:

http://mdb-blog.blogspot.com/2010/09/c-check-if-programapplication-is.html?showComment=1300402090679#c861009270784046894

Unfortunately, there doesn't seem to be a way to get WMI to list all programs from the add/remove programs list (aka Programs and Features in Windows 7, not sure about Vista). My current code has dropped WMI in favor of using the registry. The code itself to interrogate the registry is even easier than using WMI. Sample code is in the above link.

You can use the version in Windows SDK but sometimes it might not be the same version of the .NET Framework your using, getting you the following error:

Microsoft (R) .NET Global Assembly Cache Utility. Version 3.5.21022.8 Copyright (c) Microsoft Corporation. All rights reserved. Failure adding assembly to the cache: This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded.

In .NET 4.0 you'll need to search inside Microsoft SDK v8.0A, e.g.: C:\Program Files (x86)\Microsoft SDKs\Windows\v8.0A\bin\NETFX 4.0 Tools (in my case I only have the 32 bit version installed by Visual Studio 2012).

If you want the labels to be retained for the tooltip, but not displayed below the bars the following hack might be useful. I made this change for use on an private intranet application and have not tested it for efficiency or side-effects, but it did what I needed.

At about line 71 in chart.js add a property to hide the bar labels:

// Boolean - Whether to show x-axis labels
barShowLabels: true,

At about line 1500 use that property to suppress changing this.endPoint (it seems that other portions of the calculation code are needed as chunks of the chart disappeared or were rendered incorrectly if I disabled anything more than this line).

if (this.xLabelRotation > 0) {
    if (this.ctx.barShowLabels) {
        this.endPoint -= Math.sin(toRadians(this.xLabelRotation)) * originalLabelWidth + 3;
    } else {
        // don't change this.endPoint
    }
}

At about line 1644 use the property to suppress the label rendering:

if (ctx.barShowLabels) {    
    ctx.fillText(label, 0, 0);
}

I'd like to make this change to the Chart.js source but aren't that familiar with git and don't have the time to test rigorously so would rather avoid breaking anything.

A weak entity is the entity which can't be fully identified by its own attributes and takes the foreign key as an attribute (generally it takes the primary key of the entity it is related to) in conjunction.

Examples

The existence of rooms is entirely dependent on the existence of a hotel. So room can be seen as the weak entity of the hotel.
Another example is the
bank account of a particular bank has no existence if the bank doesn't exist anymore.

You may not have permission to dba_sequences. So you can always just do:

select * from user_sequences;

sudo yum install fontconfig freetype libfreetype.so.6 libfontconfig.so.1 libstdc++.so.6

You didn't explicitly state emacs, but since you've highlighted lots of editors...

In emacs, you can use rectangles for this, where a column is a rectangle of width 1.

To create a rectangle, mark the top-left and bottom-right of the rectangle (where the bottom-right mark is one to the right of the further right point included in the rectangle. You can then manipulate via:

C-x r k
Kill the text of the region-rectangle, saving its contents as the "last killed rectangle" (kill-rectangle).

C-x r d
Delete the text of the region-rectangle (delete-rectangle).

C-x r y
Yank the last killed rectangle with its upper left corner at point (yank-rectangle).

C-x r o
Insert blank space to fill the space of the region-rectangle (open-rectangle). This pushes the previous contents of the region-rectangle rightward.

M-x clear-rectangle
Clear the region-rectangle by replacing its contents with spaces.

M-x delete-whitespace-rectangle
Delete whitespace in each of the lines on the specified rectangle, starting from the left edge column of the rectangle.

C-x r t string RET
Replace rectangle contents with string on each line. (string-rectangle).

M-x string-insert-rectangle RET string RET
Insert string on each line of the rectangle.

Simply use the macros from <float.h> and the variable-width conversion specifier (".*"):

float f = 3.14159265358979323846;
printf("%.*f\n", FLT_DIG, f);

You want to use pack and base_convert.

// Convert a string into binary
// Should output: 0101001101110100011000010110001101101011
$value = unpack('H*', "Stack");
echo base_convert($value[1], 16, 2);

// Convert binary into a string
// Should output: Stack
echo pack('H*', base_convert('0101001101110100011000010110001101101011', 2, 16));

Just want to update, that in Spring 5, as mentioned in Spring docs, Spring supports 6 scopes, four of which are available only if you use a web-aware ApplicationContext.

singleton (Default) Scopes a single bean definition to a single object instance per Spring IoC container.

prototype Scopes a single bean definition to any number of object instances.

request Scopes a single bean definition to the lifecycle of a single HTTP request; that is, each HTTP request has its own instance of a bean created off the back of a single bean definition. Only valid in the context of a web-aware Spring ApplicationContext.

session Scopes a single bean definition to the lifecycle of an HTTP Session. Only valid in the context of a web-aware Spring ApplicationContext.

application Scopes a single bean definition to the lifecycle of a ServletContext. Only valid in the context of a web-aware Spring ApplicationContext.

websocket Scopes a single bean definition to the lifecycle of a WebSocket. Only valid in the context of a web-aware Spring ApplicationContext.

I needed this, the posts helped, this gets it down to one line, and if the path isn't a path at all, it just returns and exits the method. It addresses all of the above concerns, doesn't need the trailing slash either.

if (!Directory.Exists(@"C:\folderName")) return;

here is an example where str != null but str.equals(null) when using org.json

 JSONObject jsonObj = new JSONObject("{field :null}");
 Object field = jsonObj.get("field");
 System.out.println(field != null);        // => true
 System.out.println( field.equals(null)); //=> true
 System.out.println( field.getClass());  // => org.json.JSONObject$Null

EDIT: here is the org.json.JSONObject$Null class:

/**
 * JSONObject.NULL is equivalent to the value that JavaScript calls null,
 * whilst Java's null is equivalent to the value that JavaScript calls
 * undefined.
 */
private static final class Null {

    /**
     * A Null object is equal to the null value and to itself.
     *
     * @param object
     *            An object to test for nullness.
     * @return true if the object parameter is the JSONObject.NULL object or
     *         null.
     */
    @Override
    public boolean equals(Object object) {
        return object == null || object == this;
    }  
}

Well, the simplest way using LINQ would be something like this:

list = list.OrderBy(x => x.AVC ? 0 : 1)
           .ToList();

or

list = list.OrderByDescending(x => x.AVC)
           .ToList();

I believe that the natural ordering of bool values is false < true, but the first form makes it clearer IMO, because everyone knows that 0 < 1.

Note that this won't sort the original list itself - it will create a new list, and assign the reference back to the list variable. If you want to sort in place, you should use the List<T>.Sort method.

This code works well with very few requirements on external libraries and shows a basic use of int **array.

This answer shows that each array is dynamically sized, as well as how to assign a dynamically sized leaf array into the dynamically sized branch array.

This program takes arguments from STDIN in the following format:

2 2   
3 1 5 4
5 1 2 8 9 3
0 1
1 3

Code for program below...

#include <iostream>

int main()
{
    int **array_of_arrays;

    int num_arrays, num_queries;
    num_arrays = num_queries = 0;
    std::cin >> num_arrays >> num_queries;
    //std::cout << num_arrays << " " << num_queries;

    //Process the Arrays
    array_of_arrays = new int*[num_arrays];
    int size_current_array = 0;

    for (int i = 0; i < num_arrays; i++)
    {
        std::cin >> size_current_array;
        int *tmp_array = new int[size_current_array];
        for (int j = 0; j < size_current_array; j++)
        {
            int tmp = 0;
            std::cin >> tmp;
            tmp_array[j] = tmp;
        }
        array_of_arrays[i] = tmp_array;
    }


    //Process the Queries
    int x, y;
    x = y = 0;
    for (int q = 0; q < num_queries; q++)
    {
        std::cin >> x >> y;
        //std::cout << "Current x & y: " << x << ", " << y << "\n";
        std::cout << array_of_arrays[x][y] << "\n";
    }

    return 0;
}

It's a very simple implementation of int main and relies solely on std::cin and std::cout. Barebones, but good enough to show how to work with simple multidimensional arrays.

Take advantage of as.matrix:

# keep the first column 
names <-  df.aree[,1]

# Transpose everything other than the first column
df.aree.T <- as.data.frame(as.matrix(t(df.aree[,-1])))

# Assign first column as the column names of the transposed dataframe
colnames(df.aree.T) <- names

SELECT 
(select count(*) from foo1 where ID = '00123244552000258')
+
(select count(*) from foo2 where ID = '00123244552000258')
+
(select count(*) from foo3 where ID = '00123244552000258')

This is an easy way.

Task.GetAwaiter().GetResult() is preferred over Task.Wait and Task.Result because it propagates exceptions rather than wrapping them in an AggregateException. However, all three methods cause the potential for deadlock and thread pool starvation issues. They should all be avoided in favor of async/await.

The quote below explains why Task.Wait and Task.Result don't simply contain the exception propagation behavior of Task.GetAwaiter().GetResult() (due to a "very high compatibility bar").

As I mentioned previously, we have a very high compatibility bar, and thus we’ve avoided breaking changes. As such, Task.Wait retains its original behavior of always wrapping. However, you may find yourself in some advanced situations where you want behavior similar to the synchronous blocking employed by Task.Wait, but where you want the original exception propagated unwrapped rather than it being encased in an AggregateException. To achieve that, you can target the Task’s awaiter directly. When you write “await task;”, the compiler translates that into usage of the Task.GetAwaiter() method, which returns an instance that has a GetResult() method. When used on a faulted Task, GetResult() will propagate the original exception (this is how “await task;” gets its behavior). You can thus use “task.GetAwaiter().GetResult()” if you want to directly invoke this propagation logic.

https://blogs.msdn.microsoft.com/pfxteam/2011/09/28/task-exception-handling-in-net-4-5/

“GetResult” actually means “check the task for errors”

In general, I try my best to avoid synchronously blocking on an asynchronous task. However, there are a handful of situations where I do violate that guideline. In those rare conditions, my preferred method is GetAwaiter().GetResult() because it preserves the task exceptions instead of wrapping them in an AggregateException.

http://blog.stephencleary.com/2014/12/a-tour-of-task-part-6-results.html

I fixed this issue by changing the web app to use a different "Application Pool".

In Node 8 you can use the built-in util.promisify() to asynchronously read a file like this

const {promisify} = require('util')
const fs = require('fs')
const readFileAsync = promisify(fs.readFile)

readFileAsync(`${__dirname}/my.json`, {encoding: 'utf8'})
  .then(contents => {
    const obj = JSON.parse(contents)
    console.log(obj)
  })
  .catch(error => {
    throw error
  })

• Pro base64: the encoded representation you handle is a pretty safe string. It contains neither control chars nor quotes. The latter point helps against SQL injection attempts. I wouldn't expect any problem to just add the value to a "hand coded" SQL query string.

• Pro BLOB: the database manager software knows what type of data it has to expect. It can optimize for that. If you'd store base64 in a TEXT field it might try to build some index or other data structure for it, which would be really nice and useful for "real" text data but pointless and a waste of time and space for image data. And it is the smaller, as in number of bytes, representation.

I was finally able to get this to work for my needs.

The old voted up code does not run on windows 10 system (at least not mine). The referenced MS library link below provides current examples on how to make this work. My example uses them with late bindings.

https://docs.microsoft.com/en-us/windows/win32/shell/folder-getdetailsof.

The attribute codes were different on my computer and like someone mentioned above most return blank values even if they are not. I used a for loop to cycle through all of them and found out that Title and Subject can still be accessed which is more then enough for my purposes.

Private Sub MySubNamek()
Dim objShell  As Object 'Shell
Dim objFolder As Object 'Folder

Set objShell = CreateObject("Shell.Application")
Set objFolder = objShell.NameSpace("E:\MyFolder")

If (Not objFolder Is Nothing) Then
Dim objFolderItem As Object 'FolderItem
Set objFolderItem = objFolder.ParseName("Myfilename.txt")
        For i = 0 To 288
           szItem = objFolder.GetDetailsOf(objFolderItem, i)
           Debug.Print i & " - " & szItem
       Next
Set objFolderItem = Nothing
End If

Set objFolder = Nothing
Set objShell = Nothing
End Sub

in this case the original question (yourMigrationName = CategoryIdIsLong)

To use a promise, you have to either call a function that creates a promise or you have to create one yourself. You don't really describe what problem you're really trying to solve, but here's how you would create a promise yourself:

function justTesting(input) {_x000D_
    return new Promise(function(resolve, reject) {_x000D_
        // some async operation here_x000D_
        setTimeout(function() {_x000D_
            // resolve the promise with some value_x000D_
            resolve(input + 10);_x000D_
        }, 500);_x000D_
    });_x000D_
}_x000D_
_x000D_
justTesting(29).then(function(val) {_x000D_
   // you access the value from the promise here_x000D_
   log(val);_x000D_
});_x000D_
_x000D_
// display output in snippet_x000D_
function log(x) {_x000D_
    document.write(x);_x000D_
}

Or, if you already have a function that returns a promise, you can use that function and return its promise:

// function that returns a promise_x000D_
function delay(t) {_x000D_
  return new Promise(function(resolve) {_x000D_
    setTimeout(function() {_x000D_
      resolve();_x000D_
    }, t);_x000D_
  });_x000D_
}_x000D_
_x000D_
function justTesting(input) {_x000D_
  return delay(100).then(function() {_x000D_
    return input + 10;_x000D_
  });_x000D_
}_x000D_
_x000D_
justTesting(29).then(function(val) {_x000D_
  // you access the value from the promise here_x000D_
  log(val);_x000D_
});_x000D_
_x000D_
// display output in snippet_x000D_
function log(x) {_x000D_
  document.write(x);_x000D_
}

Let us assume you have a margin-bottom property set to 20px / 20% / 20em. To get the value as a number there are two options:

Option 1:

parseInt($('#some_DOM_element_ID').css('margin-bottom'), 10);

The parseInt() function parses a string and returns an integer. Don't change the 10 found in the above function (known as a "radix") unless you know what you are doing.

Example Output will be: 20 (if margin-bottom set in px) for % and em it will output the relative number based on current Parent Element / Font size.

Option 2 (I personally prefer this option)

parseFloat($('#some_DOM_element_ID').css('margin-bottom'));

Example Output will be: 20 (if margin-bottom set in px) for % and em it will output the relative number based on current Parent Element / Font size.

The parseFloat() function parses a string and returns a floating point number.

The parseFloat() function determines if the first character in the specified string is a number. If it is, it parses the string until it reaches the end of the number, and returns the number as a number, not as a string.

The advantage of Option 2 is that if you get decimal numbers returned (e.g. 20.32322px) you will get the number returned with the values behind the decimal point. Useful if you need specific numbers returned, for example if your margin-bottom is set in em or %

public class A implements C,D {...} valid

this is the way to implement multiple inheritence in java

For a Windows console app, you want to use SetConsoleCtrlHandler to handle CTRL+C and CTRL+BREAK.

See here for an example.

Check if a program exists from a Bash script covers this very well. In any shell script, you're best off running command -v $command_name for testing if $command_name can be run. In bash you can use hash $command_name, which also hashes the result of any path lookup, or type -P $binary_name if you only want to see binaries (not functions etc.)

With the latest version (2.8) of the Maven Dependency Plugin, downloading an artifact from the Maven Central Repository is as simple as:

mvn org.apache.maven.plugins:maven-dependency-plugin:2.8:get -Dartifact=groupId:artifactId:version[:packaging[:classifier]]

where groupId:artifactId:version, etc. are the Maven coordinates

An example, tested with Maven 2.0.9, Maven 2.2.1, and Maven 3.0.4:

mvn org.apache.maven.plugins:maven-dependency-plugin:2.8:get -Dartifact=org.hibernate:hibernate-entitymanager:3.4.0.GA:jar:sources

There is the easy way

HTML:

<input type="checkbox" name="test[]" />x
<input type="checkbox" name="test[]"  />y
<input type="checkbox" name="test[]" />z
<button type="button" id="submit">Submit</button>

JQUERY:

$("#submit").on("click",function(){
    if (($("input[name*='test']:checked").length)<=0) {
        alert("You must check at least 1 box");

For this you not need any plugin. Enjoy;)

There are lots of differences between ISO 8601 and RFC 3339. Here is some examples to give you an idea:

2020-12-09T16:09:53+00:00 is a date time value that is compliant both both standards.

2020-12-09 16:09:53+00:00 uses a space to separate the date and time. This is allowed by RFC 3339 but not allowed by ISO 8601.

2020-12-09T16:09:53-00:00 has a negative sign in the time offset. This is allowed by RFC 3339 but not allowed by ISO 8601.

20201209T160953Z omits the hyphens. This is allowed by ISO 8601 but not allowed by RFC 3339.

ISO 8601 allows for things like ordinal dates such as 2020-344 which represents the 344th day of year 2020. RFC 3339 doesn't allow for that.

For your questions:

Is one just an extension?

No. As shown above each standard supports syntax variations not supported by the the other standard. So one syntax is not a superset or an extension of the other.

Should I use one over the other?

Of course this depends on your scenario. A safe general strategy is to generate date time strings that are valid by both standards.

Another good general strategy is to use an existing standard library for parsing/formatting date time strings and not write custom implementations unless you are addressing a genuinely custom scenario.

Do I really need to care that bad?

Well, that's up to you. Most regular developers who deal with date time strings should have a high level understanding but don't need to dive into the details.

Disabling Lint warnings will easily get you into trouble later on. You're better off just specifying contentDescription for all of your ImageViews. If you don't need a description, then just use:

android:contentDescription="@null"

Actually xcopy does not ask you if the original file exists, but if you want to put it in a new folder named Shapes.atc, or in the folder Support (which is what you want.

To prevent xcopy from asking this, just tell him the destination folder, so there's no ambiguity:

xcopy /s/y "J:\Old path\Shapes.atc" "C:\Documents and Settings\his name\Support"

If you want to change the filename in destination just use copy (which is more adapted than xcopy when copying files):

copy /y "J:\Old path\Shapes.atc" "C:\Documents and Settings\his name\Support\Shapes-new.atc

You have the annotation in the wrong place - it needs to be on the class, not the field. i.e:

@JsonInclude(Include.NON_NULL) //or Include.NON_EMPTY, if that fits your use case 
public static class Request {
  // ...
}

As noted in comments, in versions below 2.x the syntax for this annotation is:

@JsonSerialize(include = JsonSerialize.Inclusion.NON_NULL) // or JsonSerialize.Inclusion.NON_EMPTY

The other option is to configure the ObjectMapper directly, simply by calling mapper.setSerializationInclusion(Include.NON_NULL);

(for the record, I think the popularity of this answer is an indication that this annotation should be applicable on a field-by-field basis, @fasterxml)

It really depends :) One of the handy linux core utils (info coreutils) is xargs. If you are using awk you probably have a more involved use-case in mind - your question is not very detailled.

printf "1 2\n3 4" | awk '{ print $2 }' | xargs touch

Will execute touch 2 4. Here touch could be replaced by your program. More info at info xargs and man xargs (really, read these). I believe you would like to replace touch with your program.

Breakdown of beforementioned script:

printf "1 2\n3 4"
# Output:
1 2
3 4

# The pipe (|) makes the output of the left command the input of
# the right command (simplified)
printf "1 2\n3 4" | awk '{ print $2 }'
# Output (of the awk command):
2
4

# xargs will execute a command with arguments. The arguments
# are made up taking the input to xargs (in this case the output
# of the awk command, which is "2 4".
printf "1 2\n3 4" | awk '{ print $2 }' | xargs touch
# No output, but executes: `touch 2 4` which will create (or update
# timestamp if the files already exist) files with the name "2" and "4"

Update In the original answer, I used echo instead of printf. However, printf is the better and more portable alternative as was pointed out by a comment (where great links with discussions can be found).

You can use max() to get the max value. The max function can also return the index of the maximum value in the vector. To get this, assign the result of the call to max to a two element vector instead of just a single variable.

e.g. z is your array,

>> [x, y] = max(z)

x =

7

y =

4

Here, 7 is the largest number at the 4th position(index).

    }, {
        duration: 1000,
        easing: 'swing',
        step: function () {
            $(self).text(Math.ceil(this.Counter));
        }
    });
});

Another way to do this and keep the references to this would be

$('.Count').each(function () {
    $(this).prop('Counter',0).animate({
        Counter: $(this).text()
    }, {
        duration: 1000,
        easing: 'swing',
        step: function (now) {
            $(this).text(Math.ceil(now));
        }
    });
});

FIDDLE

List<string> empnames = emplist.Select(e => e.Ename).ToList();

This is an example of Projection in Linq. Followed by a ToList to resolve the IEnumerable<string> into a List<string>.

Alternatively in Linq syntax (head compiled):

var empnamesEnum = from emp in emplist 
                   select emp.Ename;
List<string> empnames = empnamesEnum.ToList();

Projection is basically representing the current type of the enumerable as a new type. You can project to anonymous types, another known type by calling constructors etc, or an enumerable of one of the properties (as in your case).

For example, you can project an enumerable of Employee to an enumerable of Tuple<int, string> like so:

var tuples = emplist.Select(e => new Tuple<int, string>(e.EID, e.Ename));

Try to use this.

        for (int i = 0; i < chBoxListTables.Items.Count; i++)
        {
            if (chBoxListTables.Items[i].Selected)
            {
                string str = chBoxListTables.Items[i].Text;
                MessageBox.Show(str);

                var itemValue = chBoxListTables.Items[i].Value;
            }
        }

The "V" should be in CAPS in Value.

Here is another code example used in WinForm app and runs properly.

        var chBoxList= new CheckedListBox();
        chBoxList.Items.Add(new ListItem("One", "1"));
        chBoxList.Items.Add(new ListItem("Two", "2"));
        chBoxList.SetItemChecked(1, true);

        var checkedItems = chBoxList.CheckedItems;
        var chkText = ((ListItem)checkedItems[0]).Text;
        var chkValue = ((ListItem)checkedItems[0]).Value;
        MessageBox.Show(chkText);
        MessageBox.Show(chkValue);

This is an older question, but if you are using event delegation this is what caused it for me.

After removing .delegate-two it stopped executing twice. I believe this happens if both delegates are present on the same page.

$('.delegate-one, .delegate-two').on('click', '.button', function() {
    /* CODE */
});

const url = 'data:image/png;base6....';
fetch(url)
  .then(res => res.blob())
  .then(blob => {
    const file = new File([blob], "File name",{ type: "image/png" })
  })

Base64 String -> Blob -> File.

Copy and paste one of the .ts video files into a new tab in Chrome. Remove the identifying number of the .ts file (0,1,2,3 etc. or whatever number it is) and change the extension from ".ts" to ".mp4". That should bring up the video file in your browser as usual.

SLF4J 1.5.11 and 1.6.0 versions are not compatible (see compatibility report) because the argument list of org.slf4j.spi.LocationAwareLogger.log method has been changed (added Object[] p5):

SLF4J 1.5.11:

LocationAwareLogger.log ( org.slf4j.Marker p1, String p2, int p3,
                          String p4, Throwable p5 )

SLF4J 1.6.0:

LocationAwareLogger.log ( org.slf4j.Marker p1, String p2, int p3,
                          String p4, Object[] p5, Throwable p6 )

See compatibility reports for other SLF4J versions on this page.

You can generate such reports by the japi-compliance-checker tool.

Your cases does not have a return value.

getButtons().get(i).setText("§");

In-line-if is Ternary operation all ternary operations must have return value. That variable is likely void and does not return anything and it is not returning to a variable. Example:

int i = 40;
String value = (i < 20) ? "it is too low" : "that is larger than 20";

for your case you just need an if statement.

if (compareChar(curChar, toChar("0"))) { getButtons().get(i).setText("§"); }

Also side note you should use curly braces it makes the code more readable and declares scope.

string[] lines = input.Split(new[] { '\r', '\n' }, StringSplitOptions.RemoveEmptyEntries);

• Remove the file from the index, but keep it versioned and left with uncommitted changes in working copy:

  git reset head <file>
  

• Reset the file to the last state from HEAD, undoing changes and removing them from the index:

  git reset HEAD <file>
  git checkout <file>
  
  # If you have a `<branch>` named like `<file>`, use:
  git checkout -- <file>
  

  This is needed since git reset --hard HEAD won't work with single files.

• Remove <file> from index and versioning, keeping the un-versioned file with changes in working copy:

  git rm --cached <file>
  

• Remove <file> from working copy and versioning completely:

  git rm <file>
  

Update:

MongoServer.Create is obsolete now (thanks to @aknuds1). Instead this use following code:

var _server = new MongoClient(connectionString).GetServer();

It's easy. You should first take database name from connection string and then get database by name. Complete example:

var connectionString = "mongodb://localhost:27020/mydb";

//take database name from connection string
var _databaseName = MongoUrl.Create(connectionString).DatabaseName;
var _server = MongoServer.Create(connectionString);

//and then get database by database name:
_server.GetDatabase(_databaseName);

Important: If your database and auth database are different, you can add a authSource= query parameter to specify a different auth database. (thank you to @chrisdrobison)

From docs:

NOTE If you are using the database segment as the initial database to use, but the username and password specified are defined in a different database, you can use the authSource option to specify the database in which the credential is defined. For example, mongodb://user:pass@hostname/db1?authSource=userDb would authenticate the credential against the userDb database instead of db1.

I Had same problem and it seems that there is wrong "--launcher.library " address in eclipse.ini file. so I have just changed it and

We had the same problem discussed here.

We have a Redis hash, a key to hash entries (name/value pairs), and we needed to hold individual expiration times on each hash entry.

We implemented this by adding n bytes of prefix data containing encoded expiration information when we write the hash entry values, we also set the key to expire at the time contained in the value being written.

Then, on read, we decode the prefix and check for expiration. This is additional overhead, however, the reads are still O(n) and the entire key will expire when the last hash entry has expired.

add :

using namespace std;

right after include :P:D

Implementation wise you will often see inside super() statement in subclasses constructors, something like:

public class A extends AbstractB{

  public A(...){
     super(String constructorArgForB, ...);
     ...
  }
}

No, you need to wrap your TextBlock in a Border. Example:

<Border BorderThickness="1" BorderBrush="Black">
    <TextBlock ... />
</Border>

Of course, you can set these properties (BorderThickness, BorderBrush) through styles as well:

<Style x:Key="notCalledBorder" TargetType="{x:Type Border}">
    <Setter Property="BorderThickness" Value="1" />
    <Setter Property="BorderBrush" Value="Black" />
</Style>

<Border Style="{StaticResource notCalledBorder}">
    <TextBlock ... />
</Border>

If you want to select particular element use below code

var gridRowData = $("<your grid name>").data("kendoGrid");
var selectedItem = gridRowData.dataItem(gridRowData.select());
var quote = selectedItem["<column name>"];

I've given a more detailed answer of using vw with respect to specific container sizing in this answer, so I won't just repeat my answer here.

In summary, however, it is essentially a matter of factoring (or controlling) what the container size is going to be with respect to viewport, and then working out the proper vw sizing based on that for the container, taking mind of what needs to happen if something is dynamically resized.

So if you wanted a 5vw size at a container at 100% of the viewport width, then one at 75% of the viewport width you would probably want to be (5vw * .75) = 3.75vw.

The only working solution in my case was adding the following block to pom.xml:

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.8.0</version> <configuration> <release>12</release>
        </configuration>
        </plugin>
    </plugins>
</build>

I had this same issue, and searched the internet for a solution and none of the suggestions didn’t not open by double clicking the .jar file.

In my case the reason is I have multiple JDK & JRE versions installed on my computer. Since I am a software developer working with several different versions for different clients I need to use multiple JDKs in my PC (Windows 10 Pro). So I do not want to change the system variables (i.e. JAVA_HOME, JRE_HOME or PATH), instead I use command prompt to run java in user process whenever I wanted to use a different version.

When installing JDK it registers the .jar file association with latest version we installed in the PC. If you right click on the .jar icon and select properties, it will show that file opens with “Java(TM) Platform SE Binary”. If we look at the registry key: HKEY_CLASSES_ROOT\jarfile\shell\open\command, it will point to latest JDK version.

It is not a good idea (sometimes annoying) to change the registry key every time I want to run an app build from a different version.

So in my situation it is impossible to just double click the .jar file to execute it. But instead I found a work around solution myself.

Scenario:

Multiple JDKs (1.7, 1.8, 9.0, 10.0, 11.0, and 12.0)are installed in the PC, so the latest installed was 12.0.

Problem

Want to double click an executable .jar developed using JDK 1.8 and didn’t work

This is my work around solution:

1. Create a shortcut for the .jar file that you want to open.
2. Right click the shortcut icon and select properties -> Shortcut tab

3. Change the text in the target (for example "D:\Dev\JavaApp1.8.jar") To

   "C:\Program Files\Java\jdk1.8.0\bin\javaw.exe" -jar "D:\Dev\JavaApp1.8.jar"

4. Then click ok Double click the shortcut.

It should now open the app.

Python 3.5 + Use io module

import json
import io

my_bytes_value = b'[{\'Date\': \'2016-05-21T21:35:40Z\', \'CreationDate\': \'2012-05-05\', \'LogoType\': \'png\', \'Ref\': 164611595, \'Classe\': [\'Email addresses\', \'Passwords\'],\'Link\':\'http://some_link.com\'}]'

fix_bytes_value = my_bytes_value.replace(b"'", b'"')

my_json = json.load(io.BytesIO(fix_bytes_value))  

wget --spider -S "http://url/to/be/checked" 2>&1 | grep "HTTP/" | awk '{print $2}'

prints only the status code for you

list.setOnItemSelectedListener(new OnItemSelectedListener() {

        @Override
        public void onItemSelected(AdapterView<?> arg0, View arg1,
                int arg2, long arg3) {
            // TODO Auto-generated method stub

        }

        @Override
        public void onNothingSelected(AdapterView<?> arg0) {
            // TODO Auto-generated method stub

        }
    });

Its my code

jQuery(document).ready(function(e) {
    var WindowHeight = jQuery(window).height();

    var load_element = 0;

    //position of element
    var scroll_position = jQuery('.product-bottom').offset().top;

    var screen_height = jQuery(window).height();
    var activation_offset = 0;
    var max_scroll_height = jQuery('body').height() + screen_height;

    var scroll_activation_point = scroll_position - (screen_height * activation_offset);

    jQuery(window).on('scroll', function(e) {

        var y_scroll_pos = window.pageYOffset;
        var element_in_view = y_scroll_pos > scroll_activation_point;
        var has_reached_bottom_of_page = max_scroll_height <= y_scroll_pos && !element_in_view;

        if (element_in_view || has_reached_bottom_of_page) {
            jQuery('.product-bottom').addClass("change");
        } else {
            jQuery('.product-bottom').removeClass("change");
        }

    });

});

Its working Fine

You can also try:

INSERT IGNORE
  INTO table_1 
SELECT *
  FROM table_2
     ;

which allows those rows in table_1 to supersede those in table_2 that have a matching primary key, while still inserting rows with new primary keys.

Alternatively,

REPLACE
   INTO table_1
 SELECT *
   FROM table_2
      ;

will update those rows already in table_1 with the corresponding row from table_2, while inserting rows with new primary keys.

In addition to Jim's answer (sorry not enough rep points to make a comment), just wanted to point out that the arguments specified in PyCharm do not have special characters escaped, unlike what you would do on the command line. So, whereas on the command line you'd do:

python mediadb.py  /media/paul/New\ Volume/Users/paul/Documents/spinmaster/\*.png

the PyCharm parameter would be:

"/media/paul/New Volume/Users/paul/Documents/spinmaster/*.png"

As an alternative and superior solution, you could use a custom counter in a before element. It involves no extra HTML markup. A CSS reset should be used alongside it, or at least styling removed from the ol element (list-style-type: none, reset margin), otherwise the element will have two counters.

<ol>
    <li>First line</li>
    <li>Second line</li>
</ol>

CSS:

ol {
    counter-reset: my-badass-counter;
}
ol li:before {
    content: counter(my-badass-counter, upper-alpha);
    counter-increment: my-badass-counter;
    margin-right: 5px;
    font-weight: bold;
}

An example: http://jsfiddle.net/xpAMU/1/

File extensions do not have any bearing or impact on the content of the file. You can hold YAML content in files with any extension: .yml, .yaml or indeed anything else.

The (rather sparse) YAML FAQ recommends that you use .yaml in preference to .yml, but for historic reasons many Windows programmers are still scared of using extensions with more than three characters and so opt to use .yml instead.

So, what really matters is what is inside the file, rather than what its extension is.

I also have this problem so don't worry. It comes from mail server side due to an outside authentication issue. Open your mail and you will get a mail from the mail server telling you to enable accessibility. When you have done that, retry your program.

The @ symbol is the error control operator (aka the "silence" or "shut-up" operator). It makes PHP suppress any error messages (notice, warning, fatal, etc) generated by the associated expression. It works just like a unary operator, for example, it has a precedence and associativity. Below are some examples:

@echo 1 / 0;
// generates "Parse error: syntax error, unexpected T_ECHO" since 
// echo is not an expression

echo @(1 / 0);
// suppressed "Warning: Division by zero"

@$i / 0;
// suppressed "Notice: Undefined variable: i"
// displayed "Warning: Division by zero"

@($i / 0);
// suppressed "Notice: Undefined variable: i"
// suppressed "Warning: Division by zero"

$c = @$_POST["a"] + @$_POST["b"];
// suppressed "Notice: Undefined index: a"
// suppressed "Notice: Undefined index: b"

$c = @foobar();
echo "Script was not terminated";
// suppressed "Fatal error: Call to undefined function foobar()"
// however, PHP did not "ignore" the error and terminated the
// script because the error was "fatal"

What exactly happens if you use a custom error handler instead of the standard PHP error handler:

If you have set a custom error handler function with set_error_handler() then it will still get called, but this custom error handler can (and should) call error_reporting() which will return 0 when the call that triggered the error was preceded by an @.

This is illustrated in the following code example:

function bad_error_handler($errno, $errstr, $errfile, $errline, $errcontext) {
    echo "[bad_error_handler]: $errstr";
    return true;
}
set_error_handler("bad_error_handler");
echo @(1 / 0);
// prints "[bad_error_handler]: Division by zero"

The error handler did not check if @ symbol was in effect. The manual suggests the following:

function better_error_handler($errno, $errstr, $errfile, $errline, $errcontext) {
    if(error_reporting() !== 0) {
        echo "[better_error_handler]: $errstr";
    }
    // take appropriate action
    return true;
}

My example code was correct and the issue was something else in my actual code. Still, I know it was difficult to find examples of this so I'm answering it in case someone else is looking.

<div ng-repeat="f in foos">
  <div>
    <div ng-repeat="b in foos.bars">
      <a ng-click="addSomething($parent.$index)">Add Something</a>
    </div>
  </div>
</div>

Precision, Scale, and Length in the SQL Server 2000 documentation reads:

Precision is the number of digits in a number. Scale is the number of digits to the right of the decimal point in a number. For example, the number 123.45 has a precision of 5 and a scale of 2.

If you are using Xcode 6 and designing for iOS 8, none of these solutions are correct. To get your iPhone-only views to be sized correctly, don't turn off size classes, don't turn off inferred metrics, and don't set constraints (yet). Instead, use the size class control, which is an easy to miss text button at the bottom of Interface Builder that initially reads "wAny hAny".

Click the button, and choose Compact Width, Regular Height. This resize your views and cover all iPhone portrait orientations. Apple's docs here: https://developer.apple.com/library/ios/recipes/xcode_help-IB_adaptive_sizes/chapters/SelectingASizeClass.html or search on "Selecting a Size Class in Interface Builder"

Since you're using jQuery, you just need to attach to some specific events and some pre defined animations:

$('#cat').hover(function()
{
     // Mouse Over Callback
}, function()
{ 
     // Mouse Leave callback
});

Then, to do the animation, you simply need to call the fadeOut / fadeIn animations:

$('#dog').fadeOut(750 /* Animation Time */, function()
{
    // animation complete callback
     $('#cat').fadeIn(750);
});

Combining the two together, you would simply insert the animations in the hover callbacks (something like so, use this as a reference point):

$('#cat').hover(function()
{
     if($('#dog').is(':visible'))
        $('#dog').fadeOut(750 /* Animation Time */, function()
     {
        // animation complete callback
         $('#cat').fadeIn(750);
     });
}, function()
{ 
     // Mouse Leave callback
});

You can use input.value = JSON.stringify(obj) to transform the object to a string.
And when you need it back you can use obj = JSON.parse(input.value)

The JSON object is available on modern browsers or you can use the json2.js library from json.org

Since chrome has come up with the multiple profiles you will not get it directly in C:\Users\<Your_User_Name>\AppData\Local\Google\Chrome\User Data\Default\Extensions but you have to first type chrome://version/ in a tab and then look out for Profile path inside that and after you reach to your profile path look for Extensions folder in it and then folder with the desired extension Id

I also have a site that has numerous urls with urlencoded characters. I am finding that many web APIs (including Google webmaster tools and several Drupal modules) trip over urlencoded characters. Many APIs automatically decode urls at some point in their process and then use the result as a URL or HTML. When I find one of these problems, I usually double encode the results (which turns %2f into %252f) for that API. However, this will break other APIs which are not expecting double encoding, so this is not a universal solution.

Personally I am getting rid of as many special characters in my URLs as possible.

Also, I am using id numbers in my URLs which do not depend on urldecoding:

example.com/blog/my-amazing-blog%2fstory/yesterday

becomes:

example.com/blog/12354/my-amazing-blog%2fstory/yesterday

in this case, my code only uses 12354 to look for the article, and the rest of the URL gets ignored by my system (but is still used for SEO.) Also, this number should appear BEFORE the unused URL components. that way, the url will still work, even if the %2f gets decoded incorrectly.

Also, be sure to use canonical tags to ensure that url mistakes don't translate into duplicate content.

I know this is old, but none of these expressions worked for me (maybe it's because I'm on PHP). The following expression worked fine to validate that a number is higher than 49:

/([5-9][0-9])|([1-9]\d{3}\d*)/

The easiest way I've found to scroll a RecyclerView is as follows:

// Define the Index we wish to scroll to.
final int lIndex = 0;
// Assign the RecyclerView's LayoutManager.
this.getRecyclerView().setLayoutManager(this.getLinearLayoutManager());
// Scroll the RecyclerView to the Index.

Although the accepted answer works fine, since v0.21.0rc1 it gives a warning

UserWarning: Pandas doesn't allow columns to be created via a new attribute name

Instead, one can do

df[["X", "A", "B", "C"]].plot(x="X", kind="bar")

This is called string interpolation; it doesn't exist as such in Java.

One approach is to use String.format:

String string = String.format("A string %s", aVariable);

Another approach is to use a templating library such as Velocity or FreeMarker.

To serialize an object, do:

 using (StreamWriter myWriter = new StreamWriter(path, false))
 {
     XmlSerializer mySerializer = new XmlSerializer(typeof(your_object_type));
     mySerializer.Serialize(myWriter, objectToSerialize);
 }

Also remember that for XmlSerializer to work, you need a parameterless constructor.

I encountered this issue.

Discovered that somewhere in my code I was asking it to count starting from 0 (as you would in a C# code).

Turns out Excel counting starts at 1.

Your class shoud look something like this:

class Something {     int[] array; //global array, replace type of course     void function1() {        array = new int[10]; //let say you declare it here that will be 10 integers in size     }     void function2() {        array[0] = 12; //assing value at index 0 to 12.     } } 

That way you array will be accessible in both functions. However, you must be careful with global stuff, as you can quickly overwrite something.

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.waist2height); {
        final EditText edit = (EditText)findViewById(R.id.editText);          
        final RadioButton rb1 = (RadioButton) findViewById(R.id.radioCM);
        final RadioButton rb2 = (RadioButton) findViewById(R.id.radioFT);                       
        if(rb1.isChecked()){    
            edit.setVisibility(View.VISIBLE);              
        }
        else if(rb2.isChecked()){               
            edit.setVisibility(View.INVISIBLE);
        }
}

I think this is what we like to do very much.

--Step 1: (create a new user)
create LOGIN hello WITH PASSWORD='foo', CHECK_POLICY = OFF;


-- Step 2:(deny view to any database)
USE master;
GO
DENY VIEW ANY DATABASE TO hello; 


 -- step 3 (then authorized the user for that specific database , you have to use the  master by doing use master as below)
USE master;
GO
ALTER AUTHORIZATION ON DATABASE::yourDB TO hello;
GO

If you already created a user and assigned to that database before by doing

USE [yourDB] 
CREATE USER hello FOR LOGIN hello WITH DEFAULT_SCHEMA=[dbo] 
GO

then kindly delete it by doing below and follow the steps

   USE yourDB;
   GO
   DROP USER newlogin;
   GO

I can confirm that in Android Studio 1.x (here AS) on Windows also the right sequence is:

• File -> New
• AS opens a list where you must click on Image Asset
• AS opens a dialog where the app\src\main\res Directory Structure is automatically selected (the right choice)
• Clicking on the OK button, AS opens the Asset Studio dialog where you can find all the tools and options we had on the past Eclipse ADT

This can be done absolutely in any moments after creation of the project.

Android Studio warns you that it will overwrite the current ic_launcer, but this is exactly what we expect to do.

Indexing a list is done using double bracket, i.e. hypo_list[[1]] (e.g. have a look here: http://www.r-tutor.com/r-introduction/list). BTW: read.table does not return a table but a dataframe (see value section in ?read.table). So you will have a list of dataframes, rather than a list of table objects. The principal mechanism is identical for tables and dataframes though.

Note: In R, the index for the first entry is a 1 (not 0 like in some other languages).

Dataframes

l <- list(anscombe, iris)   # put dfs in list
l[[1]]             # returns anscombe dataframe

anscombe[1:2, 2]   # access first two rows and second column of dataset
[1] 10  8

l[[1]][1:2, 2]     # the same but selecting the dataframe from the list first
[1] 10  8

Table objects

tbl1 <- table(sample(1:5, 50, rep=T))
tbl2 <- table(sample(1:5, 50, rep=T))
l <- list(tbl1, tbl2)  # put tables in a list

tbl1[1:2]              # access first two elements of table 1 

Now with the list

l[[1]]                 # access first table from the list

1  2  3  4  5 
9 11 12  9  9 

l[[1]][1:2]            # access first two elements in first table

1  2 
9 11

avInput = Sheets("data").UsedRange
Set uvals = New Dictionary


For i = 1 To UBound(avInput, 1)
    If uvals.Exists(avInput(i, 1)) = False Then
        uvals.Add avInput(i, 1), 1
    Else
        uvals.Item(avInput(i, 1)) = uvals.Item(avInput(i, 1)) + 1
    End If
Next i

ReDim avInput(1 To uvals.Count)
i = 1

For Each kv In uvals.Keys
    avInput(i) = kv
    i = i + 1
Next kv

Set rop = Sheets("sheet2").Range("a1")
rop.Resize(UBound(avInput, 1), 1) = Application.Transpose(avInput)

Well you can disable skype to use port 80. Click tools --> Options --> Advanced --> Connection and uncheck the appropriate checkbox.

I've found that the best way to debug is to use the microsoft tool called DTCPing

1. Copy the file to both the server (DB) and the client (Application server/client pc)
   • Start it at the server and the client
   • At the server: fill in the client netbios computer name and try to setup a DTC connection
   • Restart both applications.
   • At the client: fill in the server netbios computer name and try to setup a DTC connection

I've had my fare deal of problems in our old company network, and I've got a few tips:

• if you get the error message "Gethostbyname failed" it means the computer can not find the other computer by its netbios name. The server could for instance resolve and ping the client, but that works on a DNS level. Not on a netbios lookup level. Using WINS servers or changing the LMHOST (dirty) will solve this problem.
• if you get an error "Acces Denied", the security settings don't match. You should compare the security tab for the msdtc and get the server and client to match. One other thing to look at is the RestrictRemoteClients value. Depending on your OS version and more importantly the Service Pack, this value can be different.
• Other connection problems:
  • The firewall between the server and the client must allow communication over port 135. And more importantly the connection can be initiated from both sites (I had a lot of problems with the firewall people in my company because they assumed only the server would open an connection on to that port)
  • The protocol returns a random port to connect to for the real transaction communication. Firewall people don't like that, they like to restrict the ports to a certain range. You can restrict the RPC dynamic port generation to a certain range using the keys as described in How to configure RPC dynamic port allocation to work with firewalls.

In my experience, if the DTCPing is able to setup a DTC connection initiated from the client and initiated from the server, your transactions are not the problem any more.

If it is something that you reference but never mutate, then use const:

declare const bootbox;

My problem and the solution

1. I have a 32 bit third party dll which I have installed in 2008 R2 machine which is 64 bit.

2. I have a wcf service created in .net 4.5 framework which calls the 32 bit third party dll for process. Now I have build property set to target 'any' cpu and deployed it to the 64 bit machine.

3. When Ii tried to invoke the wcf service got error "80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG"

4. Now Ii used ProcMon.exe to trace the com registry issue and identified that the process is looking for the registry entry at HKLM\CLSID and HKCR\CLSID where there is no entry.

5. Came to know that Microsoft will not register the 32 bit com components to the paths HKLM\CLSID, HKCR\CLSID in 64 bit machine rather it places the entry in HKLM\Wow6432Node\CLSID and HKCR\Wow6432Node\CLSID paths.

6. Now the conflict is 64 bit process trying to invoke 32 bit process in 64 bit machine which will look for the registry entry in HKLM\CLSID, HKCR\CLSID. The solution is we have to force the 64 bit process to look at the registry entry at HKLM\Wow6432Node\CLSID and HKCR\Wow6432Node\CLSID.

7. This can be achieved by configuring the wcf service project properties to target to 'X86' machine instead of 'Any'.

8. After deploying the 'X86' version to the 2008 R2 server got the issue "System.BadImageFormatException: Could not load file or assembly"

9. Solution to this badimageformatexception is setting the 'Enable32bitApplications' to 'True' in IIS Apppool properties for the right apppool.

I fixed the issue by opening the terminal preference general tab and changing the Command (complete path) to /bin/bash to default and then editing the ~/.zshrc file.

export PATH="all your path inside the quotes"

...without any whitespace between the PATH=" and save the file.

After saving the file, change the /bin/zsh in your command or select default

...and restart terminal and you should have your zsh shell working again!

This usually happens if you do not have java installed in your machine.

Go to command prompt and check the version of your java: type : java -version

you should get output sth like this

java version "1.8.0_241" Java(TM) SE Runtime Environment (build 1.8.0_241-b07) Java HotSpot(TM) 64-Bit Server VM (build 25.241-b07, mixed mode)

If not, go to orcale and download jdk. Check this video on how to download java and add it to the buildpath.

Swift 4 & Swift 5:

You need to add target for that button.

myButton.addTarget(self, action: #selector(connected(sender:)), for: .touchUpInside)

And of course you need to set tag of that button since you are using it.

myButton.tag = indexPath.row

You can achieve this by subclassing UITableViewCell. Use it in interface builder, drop a button on that cell, connect it via outlet and there you go.

To get the tag in the connected function:

@objc func connected(sender: UIButton){
    let buttonTag = sender.tag
}

$("head").append("<link>");
var css = $("head").children(":last");
css.attr({
      rel:  "stylesheet",
      type: "text/css",
      href: "address_of_your_css"
});

Along the lines of Sainath S.R's comment above, I was able to set a js object property name from a variable in Google Apps Script (which does not support ES6 yet) by defining the object then defining another key/value outside of the object:

var mailchimpInterests = { 
        "aGroupId": true,
    };

mailchimpInterests[salesperson] = true;

How about print (x, y) at once.

So there are two easy ways to make this work. The solution posted by Bert F works fine if you don't need to supply any other special Oracle-specific connection properties. The format for that is:

jdbc:oracle:thin:@//HOSTNAME:PORT/SERVICENAME

However, if you need to supply other Oracle-specific connection properties then you need to use the long TNSNAMES style. I had to do this recently to enable Oracle shared connections (where the server does its own connection pooling). The TNS format is:

jdbc:oracle:thin:@(description=(address=(host=HOSTNAME)(protocol=tcp)(port=PORT))(connect_data=(service_name=SERVICENAME)(server=SHARED)))

If you're familiar with the Oracle TNSNAMES file format, then this should look familiar to you. If not then just Google it for the details.

I didn't want any image so i modified the answer given by @statmaster to make it simple entry along with the other columns.

<asp:TemplateField ShowHeader="False">
        <ItemTemplate>
            <asp:LinkButton ID="LinkButton1" runat="server" CommandName="Delete" OnClientClick="return confirm('Are you sure you want to delete this entry?');">Delete </asp:LinkButton>             
        </ItemTemplate>
</asp:TemplateField>

The colour of the text can be changed using the Forecolor Property.

As RocketDonkey suggested, your module itself needs to have some docstrings.

For example, in myModule/__init__.py:

"""
The mod module
"""

You'd also want to generate documentation for each file in myModule/*.py using

pydoc myModule.thefilename

to make sure the generated files match the ones that are referenced from the main module documentation file.

I feel like none of the answers have crystallized why mapDispatchToProps is useful.

This can really only be answered in the context of the container-component pattern, which I found best understood by first reading:Container Components then Usage with React.

In a nutshell, your components are supposed to be concerned only with displaying stuff. The only place they are supposed to get information from is their props.

Separated from "displaying stuff" (components) is:

• how you get the stuff to display,
• and how you handle events.

That is what containers are for.

Therefore, a "well designed" component in the pattern look like this:

class FancyAlerter extends Component {
    sendAlert = () => {
        this.props.sendTheAlert()
    }

    render() {
        <div>
          <h1>Today's Fancy Alert is {this.props.fancyInfo}</h1>
          <Button onClick={sendAlert}/>
        </div>
     }
}

See how this component gets the info it displays from props (which came from the redux store via mapStateToProps) and it also gets its action function from its props: sendTheAlert().

That's where mapDispatchToProps comes in: in the corresponding container

// FancyButtonContainer.js

function mapDispatchToProps(dispatch) {
    return({
        sendTheAlert: () => {dispatch(ALERT_ACTION)}
    })
}

function mapStateToProps(state) {
    return({fancyInfo: "Fancy this:" + state.currentFunnyString})
}

export const FancyButtonContainer = connect(
    mapStateToProps, mapDispatchToProps)(
    FancyAlerter
)

I wonder if you can see, now that it's the container 1 that knows about redux and dispatch and store and state and ... stuff.

The component in the pattern, FancyAlerter, which does the rendering doesn't need to know about any of that stuff: it gets its method to call at onClick of the button, via its props.

And ... mapDispatchToProps was the useful means that redux provides to let the container easily pass that function into the wrapped component on its props.

All this looks very like the todo example in docs, and another answer here, but I have tried to cast it in the light of the pattern to emphasize why.

(Note: you can't use mapStateToProps for the same purpose as mapDispatchToProps for the basic reason that you don't have access to dispatch inside mapStateToProp. So you couldn't use mapStateToProps to give the wrapped component a method that uses dispatch.

I don't know why they chose to break it into two mapping functions - it might have been tidier to have mapToProps(state, dispatch, props) IE one function to do both!

1 Note that I deliberately explicitly named the container FancyButtonContainer, to highlight that it is a "thing" - the identity (and hence existence!) of the container as "a thing" is sometimes lost in the shorthand

export default connect(...) ????????????

syntax that is shown in most examples

You were on the right track with your "ng-keydown" attribute on the input, but you missed a simple step. Just because you put the ng-keydown attribute there, doesn't mean angular knows what to do with it. That's where "directives" come into play. You used the attribute correctly, but you now need to write a directive that will tell angular what to do when it sees that attribute on an html element.

The following is an example of how you would do that. We'll rename the directive from ng-keydown to on-keydown (to avoid breaking the "best practice" found here):

var mod = angular.module('mydirectives');
mod.directive('onKeydown', function() {
    return {
        restrict: 'A',
        link: function(scope, elem, attrs) {
             // this next line will convert the string
             // function name into an actual function
             var functionToCall = scope.$eval(attrs.ngKeydown);
             elem.on('keydown', function(e){
                  // on the keydown event, call my function
                  // and pass it the keycode of the key
                  // that was pressed
                  // ex: if ENTER was pressed, e.which == 13
                  functionToCall(e.which);
             });
        }
    };
});

The directive simple tells angular that when it sees an HTML attribute called "ng-keydown", it should listen to the element that has that attribute and call whatever function is passed to it. In the html you would have the following:

<input type="text" on-keydown="onKeydown">

And then in your controller (just like you already had), you would add a function to your controller's scope that is called "onKeydown", like so:

$scope.onKeydown = function(keycode){
    // do something with the keycode
}

Hopefully that helps either you or someone else who wants to know

Just for super noobs like me wondering how or what people meant by

PRAGMA table_info('table_name') 

You want to use use that as your prepare statement as shown below. Doing so selects a table that looks like this except is populated with values pertaining to your table.

cid         name        type        notnull     dflt_value  pk        
----------  ----------  ----------  ----------  ----------  ----------
0           id          integer     99                      1         
1           name                    0                       0

Where id and name are the actual names of your columns. So to get that value you need to select column name by using:

//returns the name
sqlite3_column_text(stmt, 1);
//returns the type
sqlite3_column_text(stmt, 2);

Which will return the current row's column's name. To grab them all or find the one you want you need to iterate through all the rows. Simplest way to do so would be in the manner below.

//where rc is an int variable if wondering :/
rc = sqlite3_prepare_v2(dbPointer, "pragma table_info ('your table name goes here')", -1, &stmt, NULL);

if (rc==SQLITE_OK)
{
    //will continue to go down the rows (columns in your table) till there are no more
    while(sqlite3_step(stmt) == SQLITE_ROW)
    {
        sprintf(colName, "%s", sqlite3_column_text(stmt, 1));
        //do something with colName because it contains the column's name
    }
}

Try what worked for me cool!

Create a variable private static int displayedposition = 0;

Now for the position of your RecyclerView in your Activity.

myRecyclerView.setOnScrollListener(new RecyclerView.OnScrollListener() {
            @Override
            public void onScrollStateChanged(RecyclerView recyclerView, int newState) {
                super.onScrollStateChanged(recyclerView, newState);
            }

            @Override
            public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
                super.onScrolled(recyclerView, dx, dy);

                LinearLayoutManager llm = (LinearLayoutManager) myRecyclerView.getLayoutManager();


                displayedposition = llm.findFirstVisibleItemPosition();


            }
        });

Place this statement where you want it to place the former site displayed in your view .

LinearLayoutManager llm = (LinearLayoutManager) mRecyclerView.getLayoutManager();
        llm.scrollToPositionWithOffset(displayedposition , youList.size());

Well that's it , it worked fine for me \o/

Here is how one can do it. I will give an example with joining so that it becomes super clear to someone.

$products = DB::table('products AS pr')
        ->leftJoin('product_families AS pf', 'pf.id', '=', 'pr.product_family_id')
        ->select('pr.id as id', 'pf.name as product_family_name', 'pf.id as product_family_id')
        ->orderBy('pr.id', 'desc')
        ->get();

Hope this helps.

You must add this code in global.aspx:

 protected void Application_BeginRequest(object sender, EventArgs e)
        {
            HttpContext.Current.Response.AddHeader("Access-Control-Allow-Origin", "*");
            if (HttpContext.Current.Request.HttpMethod == "OPTIONS")
            {
                HttpContext.Current.Response.AddHeader("Cache-Control", "no-cache");
                HttpContext.Current.Response.AddHeader("Access-Control-Allow-Methods", "GET, POST");
                HttpContext.Current.Response.AddHeader("Access-Control-Allow-Headers", "Content-Type, Accept");
                HttpContext.Current.Response.AddHeader("Access-Control-Max-Age", "1728000");
                HttpContext.Current.Response.End();
            }
        }

In tensorflow you create graphs and pass values to that graph. Graph does all the hardwork and generate the output based on the configuration that you have made in the graph. Now When you pass values to the graph then first you need to create a tensorflow session.

tf.Session()

Once session is initialized then you are supposed to use that session because all the variables and settings are now part of the session. So, there are two ways to pass external values to the graph so that graph accepts them. One is to call the .run() while you are using the session being executed.

Other way which is basically a shortcut to this is to use .eval(). I said shortcut because the full form of .eval() is

tf.get_default_session().run(values)

You can check that yourself. At the place of values.eval() run tf.get_default_session().run(values). You must get the same behavior.

what eval is doing is using the default session and then executing run().

"So does it mean definition equals declaration plus initialization."

Not necessarily, your declaration might be without any variable being initialized like:

 void helloWorld(); //declaration or Prototype.

 void helloWorld()
 {
    std::cout << "Hello World\n";
 } 

I think you're using the best method, though you could optimize it to:

 $("<div/>");

this is the only way i can think of doing it.

//positive to minus
int a = 5; // starting with 5 to become -5
int b = int a * 2; // b = 10
int c = a - b; // c = - 5;
std::cout << c << endl;
//outputs - 5


 //minus to positive
int a = -5; starting with -5 to become 5
int b = a * 2; 
// b = -10
int c = a + b 
// c = 5
std::cout << c << endl;
//outputs 5

Function examples

int b = 0;
int c = 0;


int positiveToNegative (int a) {
    int b = a * 2;
    int c = a - b;
    return c;
}

int negativeToPositive (int a) { 
    int b = a * 2;
    int c = a + b;
    return c; 
}

$data = $this->db->get_where('columnname',array('code' => 'B'));
$this->db->where_in('columnname',$data);
$this->db->where('code !=','B');
$query =  $this->db->get();
return $query->result_array();

I had to use COUNTIF() in my case as part of my SELECT columns AND to mimic a % of the number of times each item appeared in my results.

So I used this...

SELECT COL1, COL2, ... ETC
       (1 / SELECT a.vcount 
            FROM (SELECT vm2.visit_id, count(*) AS vcount 
                  FROM dbo.visitmanifests AS vm2 
                  WHERE vm2.inactive = 0 AND vm2.visit_id = vm.Visit_ID 
                  GROUP BY vm2.visit_id) AS a)) AS [No of Visits],
       COL xyz
FROM etc etc

Of course you will need to format the result according to your display requirements.

use return in the if condition will returns you out from the function, so that you can use return to break the the if condition.

It's the default formatting that Oracle provides. If you want leading zeros on output, you'll need to explicitly provide the format. Use:

SELECT TO_CHAR(0.56,'0.99') FROM DUAL;

or even:

SELECT TO_CHAR(.56,'0.99') FROM DUAL;

The same is true for trailing zeros:

SQL> SELECT TO_CHAR(.56,'0.990') val FROM DUAL;

VAL
------
 0.560

The general form of the TO_CHAR conversion function is:

TO_CHAR(number, format)

To get the whole row containing the max date for the user:

select username, date, value
from tablename where (username, date) in (
    select username, max(date) as date
    from tablename
    group by username

If you really want to use a set:

String[] strArray = {"foo", "foo", "bar"};  
Set<String> mySet = new HashSet<String>(Arrays.asList(strArray));
System.out.println(mySet);

output:

[foo, bar]

In addition to the differences mentioned in other answers, there also is a speed difference. d = {} is over twice as fast:

python -m timeit -s "d = {}" "for i in xrange(500000): d.clear()"
10 loops, best of 3: 127 msec per loop

python -m timeit -s "d = {}" "for i in xrange(500000): d = {}"
10 loops, best of 3: 53.6 msec per loop

Telerik also has a combo box control. Essentially, it's a textbox with images that when you click on them reveal a panel with a list of predefined options.

But this is AJAX, so it may have a larger footprint than you want on your website (since you say it's "HTML").

I ran into this in IntelliJ and fixed it by adding the following to my pom:

<!-- logging dependencies -->
    <dependency>
        <groupId>ch.qos.logback</groupId>
        <artifactId>logback-classic</artifactId>
        <version>${logback.version}</version>
        <exclusions>
            <exclusion>
                <!-- Defined below -->
                <artifactId>slf4j-api</artifactId>
                <groupId>org.slf4j</groupId>
            </exclusion>
        </exclusions>
    </dependency>

    <dependency>
        <groupId>org.slf4j</groupId>

    </dependency>

You can for example create an instance of List<object>, which implements IEnumerable<object>. Example:

List<object> list = new List<object>();
list.Add(1);
list.Add(4);
list.Add(5);

IEnumerable<object> en = list;
CallFunction(en);

We can achieve by Bootstrap 4 Flexbox:

<div class="d-flex justify-content-between w-100">
<p>TotalCost</p> <p>$42</p>
</div>

d-flex // Display Flex
justify-content-between // justify-content:space-between
w-100 // width:100%

Example: JSFiddle

int rotation =  getWindowManager().getDefaultDisplay().getRotation();

this will gives all orientation like normal and reverse

and handle it like

int angle = 0;
switch (rotation) {
    case Surface.ROTATION_90:
        angle = -90;
        break;
    case Surface.ROTATION_180:
        angle = 180;
        break;
    case Surface.ROTATION_270:
        angle = 90;
        break;
    default:
        angle = 0;
        break;
}

You need to loop over loadDT.Columns, like this:

foreach (DataColumn column in loadDT.Columns)
{
    Console.Write("Item: ");
    Console.Write(column.ColumnName);
    Console.Write(" ");
    Console.WriteLine(row[column]);
}

In my case i had to load images on radio button click, I just uses the regular onclick event and it worked for me.

 <input type="radio" name="colors" value="{{color.id}}" id="{{color.id}}-option" class="color_radion"  onclick="return get_images(this, {{color.id}})">

<script>
  function get_images(obj, color){
    console.log($("input[type='radio'][name='colors']:checked").val());

  }
  </script>

Closures can be declared as typealias as below

typealias Completion = (Bool, Any, Error) -> Void

If you want to use in your function anywhere in code; you can write like normal variable

func xyz(with param1: String, completion: Completion) {
}

Alternatively, you can just use,

<li v-for="catalog, key in catalogs">this is index {{++key}}</li>

This is working just fine.

for (var i = 0; i < cookies.split(";").length; ++i)
{
    var myCookie = cookies[i];
    var pos = myCookie.indexOf("=");
    var name = pos > -1 ? myCookie.substr(0, pos) : myCookie;
    document.cookie = name + "=;expires=Thu, 01 Jan 1970 00:00:00 GMT";
}

is there any way to get the value back after clear these ?

No, there isn't. But you shouldn't rely on this if this is related to a security question.

int cannot be null. If you are not assigning any value to int default value will be 0. If you want to check for null then make int as Integer in declaration. Then Integer object can be null. So, you can check where it is null or not. Even in javax bean validation you won't be able to get error for @NotNull annotation until the variable is declared as Integer.

If you will be doing many searches of the array, AND matching always is defined as string equivalence, then you can normalize your data and use a hash.

my @strings = qw( aAa Bbb cCC DDD eee );

my %string_lut;

# Init via slice:
@string_lut{ map uc, @strings } = ();

# or use a for loop:
#    for my $string ( @strings ) {
#        $string_lut{ uc($string) } = undef;
#    }


#Look for a string:

my $search = 'AAa';

print "'$string' ", 
    ( exists $string_lut{ uc $string ? "IS" : "is NOT" ),
    " in the array\n";

Let me emphasize that doing a hash lookup is good if you are planning on doing many lookups on the array. Also, it will only work if matching means that $foo eq $bar, or other requirements that can be met through normalization (like case insensitivity).

It looks like two of your lines are out of order. You start the process before setting up an event handler to capture the output. It's possible the process is just finishing before the event handler is added.

Switch the lines like so.

p.OutputDataReceived += ...
p.Start();        

The reindent script did not work for me, due to some missing module. Anyway, I found this sed command which does the job perfect for me:

sed -r 's/^([  ]*)([^ ])/\1\1\2/' file.py

You need module.exports:

Exports

An object which is shared between all instances of the current module and made accessible through require(). exports is the same as the module.exports object. See src/node.js for more information. exports isn't actually a global but rather local to each module.

For example, if you would like to expose variableName with value "variableValue" on sourceFile.js then you can either set the entire exports as such:

module.exports = { variableName: "variableValue" };

Or you can set the individual value with:

module.exports.variableName = "variableValue";

To consume that value in another file, you need to require(...) it first (with relative pathing):

const sourceFile = require('./sourceFile');
console.log(sourceFile.variableName);

Alternatively, you can deconstruct it.

const { variableName } = require('./sourceFile');
//            current directory --^
// ../     would be one directory down
// ../../  is two directories down

If all you want out of the file is variableName then

./sourceFile.js:

const variableName = 'variableValue'
module.exports = variableName

./consumer.js:

const variableName = require('./sourceFile')

Edit (2020):

Since Node.js version 8.9.0, you can also use ECMAScript Modules with varying levels of support. The documentation.

• For Node v13.9.0 and beyond, experimental modules are enabled by default
• For versions of Node less than version 13.9.0, use --experimental-modules

Node.js will treat the following as ES modules when passed to node as the initial input, or when referenced by import statements within ES module code:

• Files ending in .mjs.

• Files ending in .js when the nearest parent package.json file contains a top-level field "type" with a value of "module".
• Strings passed in as an argument to --eval or --print, or piped to node via STDIN, with the flag --input-type=module.

Once you have it setup, you can use import and export.

Using the example above, there are two approaches you can take

./sourceFile.js:

// This is a named export of variableName
export const variableName = 'variableValue'
// Alternatively, you could have exported it as a default. 
// For sake of explanation, I'm wrapping the variable in an object
// but it is not necessary. 
// You can actually omit declaring what variableName is here. 
// { variableName } is equivalent to { variableName: variableName } in this case. 
export default { variableName: variableName } 

./consumer.js:

// There are three ways of importing. 
// If you need access to a non-default export, then 
// you use { nameOfExportedVariable } 
import { variableName } from './sourceFile'
console.log(variableName) // 'variableValue'

// Otherwise, you simply provide a local variable name 
// for what was exported as default.
import sourceFile from './sourceFile'
console.log(sourceFile.variableName) // 'variableValue'

./sourceFileWithoutDefault.js:

// The third way of importing is for situations where there
// isn't a default export but you want to warehouse everything
// under a single variable. Say you have:
export const a = 'A'
export const b = 'B'

./consumer2.js

// Then you can import all exports under a single variable
// with the usage of * as:
import * as sourceFileWithoutDefault from './sourceFileWithoutDefault'

console.log(sourceFileWithoutDefault.a) // 'A'
console.log(sourceFileWithoutDefault.b) // 'B'

// You can use this approach even if there is a default export:
import * as sourceFile from './sourceFile'

// Default exports are under the variable default:
console.log(sourceFile.default) // { variableName: 'variableValue' }

// As well as named exports:
console.log(sourceFile.variableName) // 'variableValue

There is doing XML reading right, or doing the dodgy just to get by. Doing it right would be using proper document parsing.

Or... dodgy would be using custom text parsing with either wisuzu's response or using regular expressions with matchers.

//------------------code is return in typescript 

const updateMyData1 = (rowIndex:any, columnId:any, value:any) => {

    setItems(old => old.map((row, index) => {
        if (index === rowIndex) {
        return Object.assign(Object.assign({}, old[rowIndex]), { [columnId]: value });
    }
    return row;
}));

\begin{equation}
\resizebox{.9\hsize}{!}{$A+B+C+D+E+F+G+H+I+J+K+L+M+N+O+P+Q+R+S+T+U+V+W+X+Y+Z$}
\end{equation}

or

\begin{equation}
\resizebox{.8\hsize}{!}{$A+B+C+D+E+F+G+H+I+J+K+L+M+N+O+P+Q+R+S+T+U+V+W+X+Y+Z$}
\end{equation}

Invoke-Expression should work perfectly, just make sure you are using it correctly. For your case it should look like this:

Invoke-Expression "$scriptPath $argumentList"

I tested this approach with Get-Service and seems to be working as expected.

You would write a comparator class, for example:

struct CompareAge {
    bool operator()(Person const & p1, Person const & p2) {
        // return "true" if "p1" is ordered before "p2", for example:
        return p1.age < p2.age;
    }
};

and use that as the comparator argument:

priority_queue<Person, vector<Person>, CompareAge>

Using greater gives the opposite ordering to the default less, meaning that the queue will give you the lowest value rather than the highest.

I found the answers above to be useful however didn't fit the bill if I wanted to colorize something like log output without using any third party libraries. The following solved the issue for me:

red = 31
green = 32
blue = 34

def color (color=blue)
  printf "\033[#{color}m";
  yield
  printf "\033[0m"
end

color { puts "this is blue" }
color(red) { logger.info "and this is red" }

I hope it helps!
