"svn co --username=yourUserName --password=yourpassword http://path-to-your-svn"

Worked for me when on another user account. You will be prompted to enter username/password again though. You need to login like the above once and you are all set for the subsequent times(Unless you restart your machine).

In my case I had to move the @Service annotation from the interface to the implementation class.

There is a helpful function in the psych package.

You should try the following implementation:

psych::describeBy(data$dependentvariable, group = data$groupingvariable)

I came here looking for exporting blob into file with least effort. CLR functions is not something what I'd call least effort. Here described lazier one, using OLE Automation:

declare @init int
declare @file varbinary(max) = CONVERT(varbinary(max), N'your blob here')
declare @filepath nvarchar(4000) = N'c:\temp\you file name here.txt'

EXEC sp_OACreate 'ADODB.Stream', @init OUTPUT; -- An instace created
EXEC sp_OASetProperty @init, 'Type', 1; 
EXEC sp_OAMethod @init, 'Open'; -- Calling a method
EXEC sp_OAMethod @init, 'Write', NULL, @file; -- Calling a method
EXEC sp_OAMethod @init, 'SaveToFile', NULL, @filepath, 2; -- Calling a method
EXEC sp_OAMethod @init, 'Close'; -- Calling a method
EXEC sp_OADestroy @init; -- Closed the resources

You'll potentially need to allow to run OA stored procedures on server (and then turn it off, when you're done):

sp_configure 'show advanced options', 1;  
GO  
RECONFIGURE;  
GO  
sp_configure 'Ole Automation Procedures', 1;  
GO  
RECONFIGURE;  
GO

Just installed MongoDB via Homebrew. At the end of the installation console, you can see an output as follows:

To start mongodb:

brew services start mongodb

Or, if you don't want/need a background service you can just run:

mongod --config /usr/local/etc/mongod.conf

So, brew services start mongodb, managed to run MongoDB as a service for me.

Install PIL(Python Image Library) :

then:

from PIL import Image
myImage = Image.open("your_image_here");
myImage.show();

char **options[2][100];

declares a size-2 array of size-100 arrays of pointers to pointers to char. You'll want to remove one *. You'll also want to put your string literals in double quotes.

DateTime LastMonthLastDate = DateTime.Today.AddDays(0 - DateTime.Today.Day);
DateTime LastMonthFirstDate = LastMonthLastDate.AddDays(1 - LastMonthLastDate.Day);

Yes, it is possible to run PowerShell through the run window. However, it would be burdensome and you will need to enter in the password for computer. This is similar to how you will need to set up when you run cmd:

runas /user:(ComputerName)\(local admin) powershell.exe

So a basic example would be:

runas /user:MyLaptop\[email protected]  powershell.exe

You can find more information on this subject in Runas.

However, you could also do one more thing :

• 1: `Windows+R`
• 2: type: `powershell`
• 3: type: `Start-Process powershell -verb runAs`

then your system will execute the elevated powershell.

Example 3 in the Ruby's net/http documentation shows how to download a document over HTTP, and to output the file instead of just loading it into memory, substitute puts with a binary write to a file, e.g. as shown in Dejw's answer.

More complex cases are shown further down in the same document.

But as your system grows in size and functionality... i think that returning always a json is not a bad idea at all. Is more a architectural / "big scale design" matter.

You can think about returing always a JSON with two know fields : code and data. Where code is a numeric code specifying the success of the operation to be done and data is any aditional data related with the operation / service requested.

Come on, when we use a backend a service provider, any service can be checked to see if it worked well.

So i stick, to not let spring manage this, exposing hybrid returning operations (Some returns data other nothing...).. instaed make sure that your server expose a more homogeneous interface. Is more simple at the end of the day.

CDATA (Character DATA): It is similarly to a comment but it is part of document. i.e. CDATA is a data, it is part of the document but the data can not parsed in XML.
Note: XML comment omits while parsing an XML but CDATA shows as it is.

PCDATA (Parsed Character DATA) :By default, everything is PCDATA. PCDATA is a data, it can be parsed in XML.

hey this is the best solution I ever experienced.. this is CSS3

use following property to your div or anywhere you wanna put border trasparent

e.g.

div_class { 
 border: 10px solid #999;
 background-clip: padding-box; /* Firefox 4+, Opera, for IE9+, Chrome */
}

this will work..

DECLARE @DeleteProcCommand NVARCHAR(500)

DECLARE Syntax_Cursor CURSOR
FOR
SELECT 'DROP PROCEDURE ' + p.NAME
FROM sys.procedures p

OPEN Syntax_Cursor

FETCH NEXT FROM Syntax_Cursor

INTO @DeleteProcCommand

WHILE (@@FETCH_STATUS = 0)
BEGIN

EXEC (@DeleteProcCommand)

FETCH NEXT FROM Syntax_Cursor
INTO @DeleteProcCommand

END

CLOSE Syntax_Cursor

DEALLOCATE Syntax_Cursor

another example: google map api vs google direction api web service, while the former serves (delivers) javascript file to the site (which can then be used as an api to make new functions) , the later is a Rest web service delivering data (in json or xml format), which can be processed (but not used in an api sense).

PHP arrays are both integer-indexed and string-indexed. You can even mix them:

array('red', 'green', 'white', 'color3'=>'blue', 3=>'yellow');

What do you want the index to be for the value 'blue'? Is it 3? But that's actually the index of the value 'yellow', so that would be an ambiguity.

Another solution for you is to coerce the array to an integer-indexed list of values.

foreach (array_values($array) as $i => $value) {
  echo "$i: $value\n";
}

Output:

0: red
1: green
2: white
3: blue
4: yellow

This setting goes in your web.config file. It affects the entire application, though... I don't think you can set it per page.

<configuration>
  <system.web>
    <httpRuntime maxRequestLength="xxx" />
  </system.web>
</configuration>

"xxx" is in KB. The default is 4096 (= 4 MB).

var audioURL = window.URL.createObjectURL(blob);
audio.src = audioURL;

var reader = new window.FileReader();
reader.readAsDataURL(blob);
reader.onloadend = function () {
     base64data = reader.result;
     console.log(base64data);
}

Usage of formdata in react-native

I have used react-native-image-picker to select photo. In my case after choosing the photp from mobile. I'm storing it's info in component state. After, I'm sending POST request using fetch like below

const profile_pic = {
  name: this.state.formData.profile_pic.fileName,
  type: this.state.formData.profile_pic.type,
  path: this.state.formData.profile_pic.path,
  uri: this.state.formData.profile_pic.uri,
}
const formData = new FormData()
formData.append('first_name', this.state.formData.first_name);
formData.append('last_name', this.state.formData.last_name);
formData.append('profile_pic', profile_pic);
const Token = 'secret'

fetch('http://10.0.2.2:8000/api/profile/', {
    method: "POST",
    headers: {
      Accept: "application/json",
      "Content-Type": "multipart/form-data",
      Authorization: `Token ${Token}`
    },
    body: formData
  })
  .then(response => console.log(response.json()))

This is an old question, but I stumbled across it and thought I'd share the method I used:

var body = '<div id="anid">some <a href="link">text</a></div> and some more text';
var temp = document.createElement("div");
temp.innerHTML = body;
var sanitized = temp.textContent || temp.innerText;

sanitized will now contain: "some text and some more text"

Simple, no jQuery needed, and it shouldn't let you down even in more complex cases.

It's worth mentioning that you can specify argument ranges with this syntax.

function example() {
    echo "line1 ${@:1:1}"; #First argument
    echo "line2 ${@:2:1}"; #Second argument
    echo "line3 ${@:3}"; #Third argument onwards
}

I hadn't seen it mentioned.

Note: No, this isn't true. At some point there was a comment on this answer from Dan Piponi himself saying that the cause and effect here was exactly the opposite, that he wrote his article in response to James Iry's quip. But it seems to have been removed, perhaps by some compulsive tidier.

Below is my original answer.

It's quite possible that Iry had read From Monoids to Monads, a post in which Dan Piponi (sigfpe) derives monads from monoids in Haskell, with much discussion of category theory and explicit mention of "the category of endofunctors on Hask" . In any case, anyone who wonders what it means for a monad to be a monoid in the category of endofunctors might benefit from reading this derivation.

you can try this:

$('div#someDiv').height('');

Sorry guys, but selecting from all_tab_privs_recd where grantee = 'your user' will not give any output except public grants and current user grants if you run the select from a different (let us say, SYS) user. As documentation says,

ALL_TAB_PRIVS_RECD describes the following types of grants:

Object grants for which the current user is the grantee
Object grants for which an enabled role or PUBLIC is the grantee

So, if you're a DBA and want to list all object grants for a particular (not SYS itself) user, you can't use that system view.

In this case, you must perform a more complex query. Here is one taken (traced) from TOAD to select all object grants for a particular user:

select tpm.name privilege,
       decode(mod(oa.option$,2), 1, 'YES', 'NO') grantable,
       ue.name grantee,
       ur.name grantor,
       u.name owner,
       decode(o.TYPE#, 0, 'NEXT OBJECT', 1, 'INDEX', 2, 'TABLE', 3, 'CLUSTER',
                       4, 'VIEW', 5, 'SYNONYM', 6, 'SEQUENCE',

                       13, 'TYPE', 14, 'TYPE BODY',
                       19, 'TABLE PARTITION', 20, 'INDEX PARTITION', 21, 'LOB',
                       22, 'LIBRARY', 23, 'DIRECTORY', 24, 'QUEUE',

                       32, 'INDEXTYPE', 33, 'OPERATOR',
                       34, 'TABLE SUBPARTITION', 35, 'INDEX SUBPARTITION',
                       40, 'LOB PARTITION', 41, 'LOB SUBPARTITION',
                       42, 'MATERIALIZED VIEW',
                       43, 'DIMENSION',
                       44, 'CONTEXT', 46, 'RULE SET', 47, 'RESOURCE PLAN',
                       66, 'JOB', 67, 'PROGRAM', 74, 'SCHEDULE',

                       57, 'EDITION', 59, 'RULE',
                       62, 'EVALUATION CONTEXT',
                       'UNDEFINED') object_type,
       o.name object_name,
       '' column_name
        from sys.objauth$ oa, sys.obj$ o, sys.user$ u, sys.user$ ur, sys.user$ ue,
             table_privilege_map tpm
        where oa.obj# = o.obj#
          and oa.grantor# = ur.user#
          and oa.grantee# = ue.user#
          and oa.col# is null
          and oa.privilege# = tpm.privilege
          and u.user# = o.owner#
          and o.TYPE# in (2, 4, 6, 9, 7, 8, 42, 23, 22, 13, 33, 32, 66, 67, 74, 57)
  and ue.name = 'your user'
  and bitand (o.flags, 128) = 0
union all -- column level grants
select tpm.name privilege,
       decode(mod(oa.option$,2), 1, 'YES', 'NO') grantable,
       ue.name grantee,
       ur.name grantor,
       u.name owner,
       decode(o.TYPE#, 2, 'TABLE', 4, 'VIEW', 42, 'MATERIALIZED VIEW') object_type,
       o.name object_name,
       c.name column_name
from sys.objauth$ oa, sys.obj$ o, sys.user$ u, sys.user$ ur, sys.user$ ue,
     sys.col$ c, table_privilege_map tpm
where oa.obj# = o.obj#
  and oa.grantor# = ur.user#
  and oa.grantee# = ue.user#
  and oa.obj# = c.obj#
  and oa.col# = c.col#
  and bitand(c.property, 32) = 0 /* not hidden column */
  and oa.col# is not null
  and oa.privilege# = tpm.privilege
  and u.user# = o.owner#
  and o.TYPE# in (2, 4, 42)
  and ue.name = 'your user'
  and bitand (o.flags, 128) = 0;

This will list all object grants (including column grants) for your (specified) user. If you don't want column level grants then delete all part of the select beginning with 'union' clause.

UPD: Studying the documentation I found another view that lists all grants in much simpler way:

select * from DBA_TAB_PRIVS where grantee = 'your user';

Bear in mind that there's no DBA_TAB_PRIVS_RECD view in Oracle.

I was experiencing this segmentation fault after upgrading dlib on RPI. I tracebacked the stack as suggested by Shiplu Mokaddim above and it settled on an OpenBLAS library.

Since OpenBLAS is also multi-threaded, using it in a muilt-threaded application will exponentially multiply threads until segmentation fault. For multi-threaded applications, set OpenBlas to single thread mode.

In python virtual environment, tell OpenBLAS to only use a single thread by editing:

    $ workon <myenv>
    $ nano .virtualenv/<myenv>/bin/postactivate

and add:

    export OPENBLAS_NUM_THREADS=1 
    export OPENBLAS_MAIN_FREE=1

After reboot I was able to run all my image recognition apps on rpi3b which were previously crashing it.

The built-in comparison operations differ as in when you compare 2 numbers with floating point, the difference in data type (i.e. float or double) may result in different outcomes.

You can use settype method too!

SetType($var,"Boolean") Echo $var //see 0 or 1

Instead of

var bottom = $(window).height() - link.height();
bottom = offset.top - bottom;

Why aren't you doing

var bottom = $(window).height() - top - link.height();

Edit: Your mistake is that you're doing

bottom = offset.top - bottom;

instead of

bottom = bottom - offset.top; // or bottom -= offset.top;

I also had a similar problem.My problem was solved by doing the following:

PreparedStatements are the way to go in most, but not all cases. Sometimes you will find yourself in a situation where a query, or a part of it, has to be built and stored as a string for later use. Check out the SQL Injection Prevention Cheat Sheet on the OWASP Site for more details and APIs in different programming languages.

df[df.duplicated(['ID'], keep=False)]

it'll return all duplicated rows back to you.

According to documentation:

keep : {‘first’, ‘last’, False}, default ‘first’

• first : Mark duplicates as True except for the first occurrence.
• last : Mark duplicates as True except for the last occurrence.
• False : Mark all duplicates as True.

You can use the multi-argument constructors of the URI class. From the URI javadoc:

The multi-argument constructors quote illegal characters as required by the components in which they appear. The percent character ('%') is always quoted by these constructors. Any other characters are preserved.

So if you use

URI uri = new URI("http", "www.google.com?q=a b");

Then you get http:www.google.com?q=a%20b which isn't quite right, but it's a little closer.

If you know that your string will not have URL fragments (e.g. http://example.com/page#anchor), then you can use the following code to get what you want:

String s = "http://www.google.com?q=a b";
String[] parts = s.split(":",2);
URI uri = new URI(parts[0], parts[1], null);

To be safe, you should scan the string for # characters, but this should get you started.

we can create a class to pass more than one key or value and the object of this class can be used as a parameter in map.

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

 public class key1 {
    String b;
    String a;
    key1(String a,String b)
    {
        this.a=a;
        this.b=b;
    }
  }

public class read2 {

private static final String FILENAME = "E:/studies/JAVA/ReadFile_Project/nn.txt";

public static void main(String[] args) {

    BufferedReader br = null;
    FileReader fr = null;
    Map<key1,String> map=new HashMap<key1,String>();
    try {

        fr = new FileReader(FILENAME);
        br = new BufferedReader(fr);

        String sCurrentLine;

        br = new BufferedReader(new FileReader(FILENAME));

        while ((sCurrentLine = br.readLine()) != null) {
            String[] s1 = sCurrentLine.split(",");
            key1 k1 = new key1(s1[0],s1[2]);
            map.put(k1,s1[2]);
        }
        for(Map.Entry<key1,String> m:map.entrySet()){  
            key1 key = m.getKey();
            String s3 = m.getValue();
               System.out.println(key.a+","+key.b+" : "+s3);  
              }  
  //            }   
        } catch (IOException e) {

        e.printStackTrace();

    } finally {

        try {

            if (br != null)
                br.close();

            if (fr != null)
                fr.close();

        } catch (IOException ex) {

            ex.printStackTrace();

        }

    }

    }

 }

Connect to the database with the "system" user, and execute the following command:

show parameter service_name 

Personal preference is to use Ignore over SilentlyContinue here because it's not an error at all. Since we're expecting it to potentially be $false let's prevent it (with Ignore) from being put (albeit silently) in the $Error stack.

You can use:

if (Get-Variable 'foo' -Scope 'Global' -ErrorAction 'Ignore') {
    $true
} else {
    $false
}

More tersely:

[bool](gv foo -s global -ea ig)

Output of either:

False

Alternatively

You can trap the error that is raised when the variable doesn't exist.

try {
    Get-Variable foo -Scope Global -ErrorAction 'Stop'
} catch [System.Management.Automation.ItemNotFoundException] {
    Write-Warning $_
}

Outputs:

WARNING: Cannot find a variable with the name 'foo'.

Yeap, you just need to make . match newline :

$string =~ /(START)(.+?)(END)/s;

If you want to play nice with Windows file paths (under Cygwin) you can also try this:

fname=${fullfile##*[/|\\]}

This will account for backslash separators when using BaSH on Windows.

You can't do this with HTML. It's a server-based solution. You have to stream the file so that the browser than triggers the save dialog.

I'd advise not doing this. How a user interacts with a PDF should be left up to the user.

UPDATE (2014):

So...this answer still gets plenty of downvotes. I assume part of that is that this was answered 4 years ago and as Sarim points out, there is now the HTML 5 download attribute that can handle this.

I agree, and think Sarim's answer is good (it probably should be the chosen answer if the OP ever returns). However, this answer is still the reliable way to handle it (as Yigit Yener's answer points out and--oddly--people agree with). While the download attribute has gained support, it's still spotty:

http://caniuse.com/#feat=download

I dont think adding dual functions inside the toggle function works for a registered click event (Unless I'm missing something)

For example:

$('.btnName').click(function() {
 top.$('#panel').toggle(function() {
   $(this).animate({ 
     // style change
   }, 500);
   },
   function() {
   $(this).animate({ 
     // style change back
   }, 500);
 });

You can use CSS only to set two columns or more

A E

B

C

D

 <ul class="columns">
    <li>A</li>
    <li>B</li>
    <li>C</li>
    <li>D</li>
    <li>E</li>
</ul>

ul.columns  {
   -webkit-columns: 60px 2;
   -moz-columns: 60px 2;
    columns: 60px 2;
   -moz-column-fill: auto;
   column-fill: auto;
 }

There are a variety of tools that you can use to help diagnose this problem. The JDK includes JVisualVM that will allow you to attach to your running process and show what objects might be growing out of control. Netbeans has a wrapper around it that works fairly well. Eclipse has the Eclipse Memory Analyzer which is the one I use most often, just seems to handle large dump files a bit better. There's also a command line option, -XX:+HeapDumpOnOutOfMemoryError that will give you a file that is basically a snapshot of your process memory when your program crashed. You can use any of the above mentioned tools to look at it, it can really help a lot when diagnosing these sort of problems.

Depending on how hard the program is working, it may be a simple case of the JVM not knowing when a good time to garbage collect may be, you might also look into the parallel garbage collection options as well.

If anyone wants to enable dark mode, you may follow the below steps

• Open your Notepad++, and select “Settings” on the menu bar, and choose “Style configurator”.
• Select theme “Obsidian” (you can choose other dark themes)
• Click on Save&Colse

Consider the following code:

error_reporting(E_STRICT);
class test {
    function test_arr(&$a) {
        var_dump($a);
    }
    function get_arr() {
        return array(1, 2);
    }
}

$t = new test;
$t->test_arr($t->get_arr());

This will generate the following output:

Strict Standards: Only variables should be passed by reference in `test.php` on line 14
array(2) {
  [0]=>
  int(1)
  [1]=>
  int(2)
}

The reason? The test::get_arr() method is not a variable and under strict mode this will generate a warning. This behavior is extremely non-intuitive as the get_arr() method returns an array value.

To get around this error in strict mode, either change the signature of the method so it doesn't use a reference:

function test_arr($a) {
    var_dump($a);
}

Since you can't change the signature of array_shift you can also use an intermediate variable:

$inter = get_arr();
$el = array_shift($inter);

the best answer is @Gal Rom 's. there is more information about it: touch event return's to child views first. and if you define onClick or onTouch listener for them, parnt view (for example fragment) will not receive any touch listener. So if you want define swipe listener for fragment in this situation, you must implement it in a new class:

    package com.neganet.QRelations.fragments;

import android.content.Context;
import android.util.AttributeSet;
import android.view.MotionEvent;
import android.widget.FrameLayout;

public class SwipeListenerFragment extends FrameLayout {
    private float x1,x2;
    static final int MIN_DISTANCE=150;
    private onSwipeEventDetected mSwipeDetectedListener;


    public SwipeListenerFragment(Context context) {
        super(context);
    }

    public SwipeListenerFragment(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public SwipeListenerFragment(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent ev) {
        boolean result=false;
        switch(ev.getAction())
        {
            case MotionEvent.ACTION_DOWN:
                x1 = ev.getX();
                break;
            case MotionEvent.ACTION_UP:
                x2 = ev.getX();
                float deltaX = x2 - x1;
                if (Math.abs(deltaX) > MIN_DISTANCE)
                {
                    if(deltaX<0)
                    {
                        result=true;
                        if(mSwipeDetectedListener!=null)
                            mSwipeDetectedListener.swipeLeftDetected();

                    }else if(deltaX>0){
                        result=true;
                        if(mSwipeDetectedListener!=null)
                            mSwipeDetectedListener.swipeRightDetected();
                    }
                }
                break;
        }
        return result;
    }

    public interface onSwipeEventDetected
    {
        public void swipeLeftDetected();
        public void swipeRightDetected();

    }

    public void registerToSwipeEvents(onSwipeEventDetected listener)
    {
        this.mSwipeDetectedListener=listener;
    }
}

I changed @Gal Rom 's class. So it can detect both right and left swipe and specially it returns onInterceptTouchEvent true after detect. its important because if we dont do it some times child views maybe receive event and both of Swipe for fragment and onClick for child view (for example) runs and cause some issues. after making this class, you must change your fragment xml file:

    <com.neganet.QRelations.fragments.SwipeListenerFragment xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
    android:id="@+id/main_list_layout"
    android:clickable="true"
    android:focusable="true"
    android:focusableInTouchMode="true"
    android:layout_height="match_parent" tools:context="com.neganet.QRelations.fragments.mainList"
    android:background="@color/main_frag_back">

    <!-- TODO: Update blank fragment layout -->
    <android.support.v7.widget.RecyclerView
        android:id="@+id/farazList"
        android:scrollbars="horizontal"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_gravity="left|center_vertical" />
</com.neganet.QRelations.fragments.SwipeListenerFragment>

you see that begin tag is the class that we made. now in fragment class:

            View view=inflater.inflate(R.layout.fragment_main_list, container, false);
        SwipeListenerFragment tdView=(SwipeListenerFragment) view;
        tdView.registerToSwipeEvents(this);


and then Implement SwipeListenerFragment.onSwipeEventDetected in it:

        @Override
    public void swipeLeftDetected() {
        Toast.makeText(getActivity(), "left", Toast.LENGTH_SHORT).show();
    }

    @Override
    public void swipeRightDetected() {
        Toast.makeText(getActivity(), "right", Toast.LENGTH_SHORT).show();
    }

It's a little complicated but works perfect :)

An instance of Date always represents a date and cannot be empty. You can use a null value of date2 to represent "there is no date". You will have to check for null whenever you use date2 to avoid a NullPointerException, like when rendering your page:

if (date2 != null)
  // print date2
else
  // print nothing, or a default value

Based on the syntax provided

 Select * Where Amount = min(Amount)

You could do using:

 library(sqldf)

Using @Kara Woo's example df

  sqldf("select * from df where Amount in (select min(Amount) from df)")
  #Name Amount
 #1    B    120
 #2    E    120

They are lists because you type them as lists in the dictionary:

bikes = {
    # Bike designed for children"
    "Trike": ["Trike", 20, 100],
    # Bike designed for everyone"
    "Kruzer": ["Kruzer", 50, 165]
    }

You should use the bike-class instead:

bikes = {
    # Bike designed for children"
    "Trike": Bike("Trike", 20, 100),
    # Bike designed for everyone"
    "Kruzer": Bike("Kruzer", 50, 165)
    }

This will allow you to get the cost of the bikes with bike.cost as you were trying to.

for bike in bikes.values():
    profit = bike.cost * margin
    print(bike.name + " : " + str(profit))

This will now print:

Kruzer : 33.0
Trike : 20.0

If you have another objective of getting in values from the table then using them to be converted, you can try the following way

### pre processing
ind <- bigm.train[,lapply(.SD,is.character)]
ind <- names(ind[,.SD[T]])
### Convert multiple columns to factor
bigm.train[,(ind):=lapply(.SD,factor),.SDcols=ind]

This selects columns which are specifically character based and then converts them to factor.

PASSING TABLE AS PARAMETER IN STORED PROCEDURE

Step 1:

CREATE TABLE [DBO].T_EMPLOYEES_DETAILS ( Id int, Name nvarchar(50), Gender nvarchar(10), Salary int )

Step 2:

CREATE TYPE EmpInsertType AS TABLE ( Id int, Name nvarchar(50), Gender nvarchar(10), Salary int )

Step 3:

/* Must add READONLY keyword at end of the variable */

CREATE PROC PRC_EmpInsertType @EmployeeInsertType EmpInsertType READONLY AS BEGIN INSERT INTO [DBO].T_EMPLOYEES_DETAILS SELECT * FROM @EmployeeInsertType END

Step 4:

DECLARE @EmployeeInsertType EmpInsertType

INSERT INTO @EmployeeInsertType VALUES(1,'John','Male',50000) INSERT INTO @EmployeeInsertType VALUES(2,'Praveen','Male',60000) INSERT INTO @EmployeeInsertType VALUES(3,'Chitra','Female',45000) INSERT INTO @EmployeeInsertType VALUES(4,'Mathy','Female',6600) INSERT INTO @EmployeeInsertType VALUES(5,'Sam','Male',50000)

EXEC PRC_EmpInsertType @EmployeeInsertType

=======================================

SELECT * FROM T_EMPLOYEES_DETAILS

OUTPUT

1 John Male 50000

2 Praveen Male 60000

3 Chitra Female 45000

4 Mathy Female 6600

5 Sam Male 50000

Example simple (worked):

var a=Number.parseFloat($("#budget_project").val()); // from input field
var b=Number.parseFloat(html); // from ajax
var c=a-b;
$("#result").html(c.toFixed(2)); // put to id='result' (div or others)

Name:

1. can be used only for descendants of FrameworkElement and FrameworkContentElement;
2. can be set from code-behind via SetValue() and property-like.

x:Name:

1. can be used for almost all XAML elements;
2. can NOT be set from code-behind via SetValue(); it can only be set using attribute syntax on objects because it is a directive.

Using both directives in XAML for one FrameworkElement or FrameworkContentElement will cause an exception: if the XAML is markup compiled, the exception will occur on the markup compile, otherwise it occurs on load.

If you are working with Android's MediaStore database, here is how to store an image and then display it after it is saved.

on button click write this

 Intent in = new Intent(Intent.ACTION_PICK,
                    android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
            in.putExtra("crop", "true");
            in.putExtra("outputX", 100);
            in.putExtra("outputY", 100);
            in.putExtra("scale", true);
            in.putExtra("return-data", true);

            startActivityForResult(in, 1);

then do this in your activity

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        // TODO Auto-generated method stub
        super.onActivityResult(requestCode, resultCode, data);

        if (requestCode == 1 && resultCode == RESULT_OK && data != null) {

            Bitmap bmp = (Bitmap) data.getExtras().get("data");

            img.setImageBitmap(bmp);
            btnadd.requestFocus();

            ByteArrayOutputStream baos = new ByteArrayOutputStream();
            bmp.compress(Bitmap.CompressFormat.JPEG, 100, baos);
            byte[] b = baos.toByteArray();
            String encodedImageString = Base64.encodeToString(b, Base64.DEFAULT);

            byte[] bytarray = Base64.decode(encodedImageString, Base64.DEFAULT);
            Bitmap bmimage = BitmapFactory.decodeByteArray(bytarray, 0,
                    bytarray.length);

        }

    }

i reached this question while trying to find all procedures which use a certain table

Oracle SQL Developer offers this capability, as pointed out in this article : https://www.thatjeffsmith.com/archive/2012/09/search-and-browse-database-objects-with-oracle-sql-developer/

From the View menu, choose Find DB Object. Choose a DB connection. Enter the name of the table. At Object Types, keep only functions, procedures and packages. At Code section, check All source lines.

If you're running Spark in a larger organization and are unable to update the /spark-env.sh file, exporting the environment variables may not work.

You can add the specific Spark settings through the --conf option when submitting the job at run time.

pyspark --master yarn --[other settings]\ 
  --conf "spark.pyspark.python=/your/python/loc/bin/python"\ 
  --conf "spark.pyspark.driver.python=/your/python/loc/bin/python"

Group By X means put all those with the same value for X in the one group.

Group By X, Y means put all those with the same values for both X and Y in the one group.

To illustrate using an example, let's say we have the following table, to do with who is attending what subject at a university:

Table: Subject_Selection

+---------+----------+----------+
| Subject | Semester | Attendee |
+---------+----------+----------+
| ITB001  |        1 | John     |
| ITB001  |        1 | Bob      |
| ITB001  |        1 | Mickey   |
| ITB001  |        2 | Jenny    |
| ITB001  |        2 | James    |
| MKB114  |        1 | John     |
| MKB114  |        1 | Erica    |
+---------+----------+----------+

When you use a group by on the subject column only; say:

select Subject, Count(*)
from Subject_Selection
group by Subject

You will get something like:

+---------+-------+
| Subject | Count |
+---------+-------+
| ITB001  |     5 |
| MKB114  |     2 |
+---------+-------+

...because there are 5 entries for ITB001, and 2 for MKB114

If we were to group by two columns:

select Subject, Semester, Count(*)
from Subject_Selection
group by Subject, Semester

we would get this:

+---------+----------+-------+
| Subject | Semester | Count |
+---------+----------+-------+
| ITB001  |        1 |     3 |
| ITB001  |        2 |     2 |
| MKB114  |        1 |     2 |
+---------+----------+-------+

This is because, when we group by two columns, it is saying "Group them so that all of those with the same Subject and Semester are in the same group, and then calculate all the aggregate functions (Count, Sum, Average, etc.) for each of those groups". In this example, this is demonstrated by the fact that, when we count them, there are three people doing ITB001 in semester 1, and two doing it in semester 2. Both of the people doing MKB114 are in semester 1, so there is no row for semester 2 (no data fits into the group "MKB114, Semester 2")

Hopefully that makes sense.

You should include bootstrap-datepicker.js after bootstrap.js and you should bind the datepicker to your control.

$(function(){
   $('.datepicker').datepicker({
      format: 'mm-dd-yyyy'
    });
});

It seems it happens to us all. I was happily hacking away at javascript, nowhere near all the nasty hibernate java stuff, and boom, "cant find org.jboss.logging.BasicLoging". I havent touched anything!. After an hour or so of trying to make that appear, restarting servers, mysql, eclipse, adding jars that weren't needed before,I deployed the fix all solution, the off button. Then zap, no project. (I am still none the wiser as to why calling Configuration() should now require jboss-logging...jar, maybe I needed it all along for when bad things happen)

My input is

1. use git, keep as little of your stuff in the eclipse workspace area as possible. Then just import project from existing git repo when eclipse loses it's marbles.

2. I also lost my server config. it's there but eclipse insists there no server config stuff and bombs. So make another one, I've expressed my feelings about eclipse in my new server name, and copy your apache xml configs (workspace/Servers/I_Love_Eclipse) over from the original perfectly good directory.

I'm perhaps a bit of a perfectionist; I don't really like the ForMember(..., x => x.Ignore()) syntax. It's a little thing, but it it matters to me. I wrote this extension method to make it a bit nicer:

public static IMappingExpression<TSource, TDestination> Ignore<TSource, TDestination>(
    this IMappingExpression<TSource, TDestination> map,
    Expression<Func<TDestination, object>> selector)
{
    map.ForMember(selector, config => config.Ignore());
    return map;
}

It can be used like so:

Mapper.CreateMap<JsonRecord, DatabaseRecord>()
        .Ignore(record => record.Field)
        .Ignore(record => record.AnotherField)
        .Ignore(record => record.Etc);

You could also rewrite it to work with params, but I don't like the look of a method with loads of lambdas.

Reading the Spark documentation I found an easier solution.

Since version 1.4 of spark there is a function drop(col) which can be used in pyspark on a dataframe.

You can use it in two ways

1. df.drop('age').collect()
2. df.drop(df.age).collect()

Pyspark Documentation - Drop

How about the following?

First ask the user for the number of rows and columns, store that in say, nrows and ncols (i.e. scanf("%d", &nrows);) and then allocate memory for a 2D array of size nrows x ncols. Thus you can have a matrix of a size specified by the user, and not fixed at some dimension you've hardcoded!

Then store the elements with for(i = 0;i < nrows; ++i) ... and display the elements in the same way except you throw in newlines after every row, i.e.

for(i = 0; i < nrows; ++i)
{
   for(j = 0; j < ncols ; ++j) 
   {
      printf("%d\t",mat[i][j]);
   }
printf("\n");
}

I had a similar problem when I rearranged the folder structure of a project. I tried all the hints given in this thread but none of them worked. After checking further I discovered that I forgot to copy an important hidden file over to the new directory. That was

.angular-cli.json

from the root directory of the @angular/cli project. After I copied that file over all was running as expected.

If your terminal supports it, you can use ANSI escape codes to use color in your output. It generally works for Unix shell prompts; however, it doesn't work for Windows Command Prompt (Although, it does work for Cygwin). For example, you could define constants like these for the colors:

public static final String ANSI_RESET = "\u001B[0m";
public static final String ANSI_BLACK = "\u001B[30m";
public static final String ANSI_RED = "\u001B[31m";
public static final String ANSI_GREEN = "\u001B[32m";
public static final String ANSI_YELLOW = "\u001B[33m";
public static final String ANSI_BLUE = "\u001B[34m";
public static final String ANSI_PURPLE = "\u001B[35m";
public static final String ANSI_CYAN = "\u001B[36m";
public static final String ANSI_WHITE = "\u001B[37m";

Then, you could reference those as necessary.

For example, using the above constants, you could make the following red text output on supported terminals:

System.out.println(ANSI_RED + "This text is red!" + ANSI_RESET);

Update: You might want to check out the Jansi library. It provides an API and has support for Windows using JNI. I haven't tried it yet; however, it looks promising.

Update 2: Also, if you wish to change the background color of the text to a different color, you could try the following as well:

public static final String ANSI_BLACK_BACKGROUND = "\u001B[40m";
public static final String ANSI_RED_BACKGROUND = "\u001B[41m";
public static final String ANSI_GREEN_BACKGROUND = "\u001B[42m";
public static final String ANSI_YELLOW_BACKGROUND = "\u001B[43m";
public static final String ANSI_BLUE_BACKGROUND = "\u001B[44m";
public static final String ANSI_PURPLE_BACKGROUND = "\u001B[45m";
public static final String ANSI_CYAN_BACKGROUND = "\u001B[46m";
public static final String ANSI_WHITE_BACKGROUND = "\u001B[47m";

For instance:

System.out.println(ANSI_GREEN_BACKGROUND + "This text has a green background but default text!" + ANSI_RESET);
System.out.println(ANSI_RED + "This text has red text but a default background!" + ANSI_RESET);
System.out.println(ANSI_GREEN_BACKGROUND + ANSI_RED + "This text has a green background and red text!" + ANSI_RESET);

In python, use and instead of && like this:

#!/usr/bin/python
foo = True;
bar = True;
if foo and bar:
    print "both are true";

This prints:

both are true

Checkout this thread, it has some useful information about exiting and tracebacks.

If you are more interested in just killing the program, try something like this (this will take the legs out from under the cleanup code as well):

if __name__ == '__main__':
    try:
        main()
    except KeyboardInterrupt:
        print('Interrupted')
        try:
            sys.exit(0)
        except SystemExit:
            os._exit(0)

If you really want something like goto statements, you could always try breaking to named blocks.

You have to be within the scope of the block to break to the label:

namedBlock: {
  if (j==2) {
    // this will take you to the label above
    break namedBlock;
  }
}

I won't lecture you on why you should avoid goto's - I'm assuming you already know the answer to that.

i know a way ny which you can call you private function to test in mockito

@Test
    public  void  commandEndHandlerTest() throws  Exception
    {
        Method retryClientDetail_privateMethod =yourclass.class.getDeclaredMethod("Your_function_name",null);
        retryClientDetail_privateMethod.setAccessible(true);
        retryClientDetail_privateMethod.invoke(yourclass.class, null);
    }

Query would be like this:

SELECT ID, AccountID, Quantity, 
       SUM(Quantity) OVER (PARTITION BY AccountID ) AS TopBorcT 

       FROM #Empl ORDER BY AccountID

Partition by works like group by. Here we are grouping by AccountID so sum would be corresponding to AccountID.

First first case, AccountID = 1 , then sum(quantity) = 10 + 5 + 2 => 17 & For AccountID = 2, then sum(Quantity) = 7+3 => 10

so result would appear like attached snapshot.

What you are asking, Sir, is as the answer of RedFilter. This answer as well helps in understanding why group by is somehow a simpler version or partition over: SQL Server: Difference between PARTITION BY and GROUP BY since it changes the way the returned value is calculated and therefore you could (somehow) return columns group by can not return.

Map.keys() returns a MapIterator object which can be converted to Array using Array.from:

let keys = Array.from( myMap.keys() );
// ["a", "b"]

EDIT: you can also convert iterable object to array using spread syntax

let keys =[ ...myMap.keys() ];
// ["a", "b"]

After posting this I did come up with a way that works. However, I don't feel it is the best way to handle this. Any suggestions on a better one?

//Check to see if we get rows back, if we do just bind.

if (dtFunding.Rows.Count != 0)
{
    grdFunding.DataSource = dtFunding;
    grdFunding.DataBind();
}
else
{
  //Other wise add a emtpy "New Row" to the datatable and then hide it after binding.

     dtFunding.Rows.Add(dtFunding.NewRow());
     grdFunding.DataSource = dtFunding;
     grdFunding.DataBind();
     grdFunding.Rows[0].Visible = false;
}

You can use this not only in entities but also store procedure or other data source:

var customer = (from cus in _billingCommonservice.BillingUnit.CustomerRepository.GetAll()  
                          join man in _billingCommonservice.BillingUnit.FunctionRepository.ManagersCustomerValue()  
                          on cus.CustomerID equals man.CustomerID  
                          // start left join  
                          into a  
                          from b in a.DefaultIfEmpty(new DJBL_uspGetAllManagerCustomer_Result() )  
                          select new { cus.MobileNo1,b.ActiveStatus });

it depends on what role this foreign key plays in your relation.

1. if this foreign key is also a key attribute in your relation, then it can't be NULL
2. if this foreign key is a normal attribute in your relation, then it can be NULL.

And if you just want to get the directory name and no need for the filename coming with it, then you can do that in the following conventional way using os Python module.

>>> import os
>>> f = open('/Users/Desktop/febROSTER2012.xls')
>>> os.path.dirname(f.name)
>>> '/Users/Desktop/'

This way you can get hold of the directory structure.

My problem was that I had this: Instead of this:

The quickest way to check is just to write "inetmgr" at run (By pressing Win + R) as a command, if a manager window is appeared then it's installed otherwise it isn't.

It turned out that my problem was that I was using a load balancer to handle the SSL, which then sent it over http to the actual server, which then complained.

Description of a fix is here: http://blog.hackedbrain.com/2006/09/26/how-to-ssl-passthrough-with-wcf-or-transportwithmessagecredential-over-plain-http/

Edit: I fixed my problem, which was slightly different, after talking to microsoft support.

My silverlight app had its endpoint address in code going over https to the load balancer. The load balancer then changed the endpoint address to http and to point to the actual server that it was going to. So on each server's web config I added a listenUri for the endpoint that was http instead of https

<endpoint address="" listenUri="http://[LOAD_BALANCER_ADDRESS]" ... />

Since Android M things have got more complicated. The answer of android.net.URI.getQueryParameter() has a bug which breaks spaces before JellyBean. Apache URLEncodedUtils.parse() worked, but was deprecated in L, and removed in M.

So the best answer now is UrlQuerySanitizer. This has existed since API level 1 and still exists. It also makes you think about the tricky issues like how do you handle special characters, or repeated values.

The simplest code is

UrlQuerySanitizer.ValueSanitizer sanitizer = UrlQuerySanitizer.getAllButNullLegal();
// remember to decide if you want the first or last parameter with the same name
// If you want the first call setPreferFirstRepeatedParameter(true);
sanitizer.parseUrl(url);
String value = sanitizer.getValue("paramName");

If you are happy with the default parsing behavior you can do:

new UrlQuerySanitizer(url).getValue("paramName")

but you should make sure you understand what the default parsing behavor is, as it might not be what you want.

There is no guarantee that your threads are executing simultaneously regardless of any trivial example anyone else posts. If your OS only gives the java process one processor to work on, your java threads will still be scheduled for each time slice in a round robin fashion. Meaning, no two will ever be executing simultaneously, but the work they do will be interleaved. You can use monitoring tools like Java's Visual VM (standard in the JDK) to observe the threads executing in a Java process.

As the error says your router link should match the existing routes configured

It should be just routerLink="/about"

If you are only looking to point to a different location for you identity file, the you can modify your ~/.ssh/config file with the following entry:

IdentityFile ~/.foo/identity

man ssh_config to find other config options.

If it helps you can embed a tab character in a double quoted string:

Prasoon has already offered up a host of different (and good) ways to do this, none of which need repeating here. I'd like to suggest an alternative approach for speed however.

If you're going to be doing this quite a bit, you may want to consider "sub-classing" your vector so that a sum of elements is maintained separately (not actually sub-classing vector which is iffy due to the lack of a virtual destructor - I'm talking more of a class that contains the sum and a vector within it, has-a rather than is-a, and provides the vector-like methods).

For an empty vector, the sum is set to zero. On every insertion to the vector, add the element being inserted to the sum. On every deletion, subtract it. Basically, anything that can change the underlying vector is intercepted to ensure the sum is kept consistent.

That way, you have a very efficient O(1) method for "calculating" the sum at any point in time (just return the sum currently calculated). Insertion and deletion will take slightly longer as you adjust the total and you should take this performance hit into consideration.

Vectors where the sum is needed more often than the vector is changed are the ones likely to benefit from this scheme, since the cost of calculating the sum is amortised over all accesses. Obviously, if you only need the sum every hour and the vector is changing three thousand times a second, it won't be suitable.

Something like this would suffice:

class UberVector:
    private Vector<int> vec
    private int sum

    public UberVector():
        vec = new Vector<int>()
        sum = 0

    public getSum():
        return sum

    public add (int val):
        rc = vec.add (val)
        if rc == OK:
            sum = sum + val
        return rc

    public delindex (int idx):
        val = 0
        if idx >= 0 and idx < vec.size:
            val = vec[idx]
        rc =  vec.delindex (idx)
        if rc == OK:
            sum = sum - val
        return rc

Obviously, that's pseudo-code and you may want to have a little more functionality, but it shows the basic concept.

If you prefer a non-object-oriented approach, move plt.xticks(rotation=70) to right before the two avail_plot calls, eg

plt.xticks(rotation=70)
avail_plot(axs[0], dates, s1, 'testing', 'green')
avail_plot(axs[1], dates, s1, 'testing2', 'red')

This sets the rotation property before setting up the labels. Since you have two axes here, plt.xticks gets confused after you've made the two plots. At the point when plt.xticks doesn't do anything, plt.gca() does not give you the axes you want to modify, and so plt.xticks, which acts on the current axes, is not going to work.

For an object-oriented approach not using plt.xticks, you can use

plt.setp( axs[1].xaxis.get_majorticklabels(), rotation=70 )

after the two avail_plot calls. This sets the rotation on the correct axes specifically.

The loc parameter specifies in which corner of the bounding box the legend is placed. The default for loc is loc="best" which gives unpredictable results when the bbox_to_anchor argument is used.
Therefore, when specifying bbox_to_anchor, always specify loc as well.

The default for bbox_to_anchor is (0,0,1,1), which is a bounding box over the complete axes. If a different bounding box is specified, is is usually sufficient to use the first two values, which give (x0, y0) of the bounding box.

Below is an example where the bounding box is set to position (0.6,0.5) (green dot) and different loc parameters are tested. Because the legend extents outside the bounding box, the loc parameter may be interpreted as "which corner of the legend shall be placed at position given by the 2-tuple bbox_to_anchor argument".

import matplotlib.pyplot as plt
plt.rcParams["figure.figsize"] = 6, 3
fig, axes = plt.subplots(ncols=3)
locs = ["upper left", "lower left", "center right"]
for l, ax in zip(locs, axes.flatten()):
    ax.set_title(l)
    ax.plot([1,2,3],[2,3,1], "b-", label="blue")
    ax.plot([1,2,3],[1,2,1], "r-", label="red")
    ax.legend(loc=l, bbox_to_anchor=(0.6,0.5))
    ax.scatter((0.6),(0.5), s=81, c="limegreen", transform=ax.transAxes)

plt.tight_layout()    
plt.show()

See especially this answer for a detailed explanation and the question What does a 4-element tuple argument for 'bbox_to_anchor' mean in matplotlib? .

ax.legend(bbox_to_anchor=(1,0), loc="lower right",  bbox_transform=fig.transFigure)

It may not make too much sense to use data coordinates, but since you asked for it this would be done via bbox_transform=ax.transData.

In a Nutshell

An unwind segue (sometimes called exit segue) can be used to navigate back through push, modal or popover segues (as if you popped the navigation item from the navigation bar, closed the popover or dismissed the modally presented view controller). On top of that you can actually unwind through not only one but a series of push/modal/popover segues, e.g. "go back" multiple steps in your navigation hierarchy with a single unwind action.

When you perform an unwind segue, you need to specify an action, which is an action method of the view controller you want to unwind to.

Objective-C:

- (IBAction)unwindToThisViewController:(UIStoryboardSegue *)unwindSegue
{
}

Swift:

@IBAction func unwindToThisViewController(segue: UIStoryboardSegue) {
}

The name of this action method is used when you create the unwind segue in the storyboard. Furthermore, this method is called just before the unwind segue is performed. You can get the source view controller from the passed UIStoryboardSegue parameter to interact with the view controller that initiated the segue (e.g. to get the property values of a modal view controller). In this respect, the method has a similar function as the prepareForSegue: method of UIViewController.

iOS 8 update: Unwind segues also work with iOS 8's adaptive segues, such as Show and Show Detail.

An Example

Let us have a storyboard with a navigation controller and three child view controllers:

From Green View Controller you can unwind (navigate back) to Red View Controller. From Blue you can unwind to Green or to Red via Green. To enable unwinding you must add the special action methods to Red and Green, e.g. here is the action method in Red:

Objective-C:

@implementation RedViewController

- (IBAction)unwindToRed:(UIStoryboardSegue *)unwindSegue
{
}

@end

Swift:

@IBAction func unwindToRed(segue: UIStoryboardSegue) {
}

After the action method has been added, you can define the unwind segue in the storyboard by control-dragging to the Exit icon. Here we want to unwind to Red from Green when the button is pressed:

You must select the action which is defined in the view controller you want to unwind to:

You can also unwind to Red from Blue (which is "two steps away" in the navigation stack). The key is selecting the correct unwind action.

Before the the unwind segue is performed, the action method is called. In the example I defined an unwind segue to Red from both Green and Blue. We can access the source of the unwind in the action method via the UIStoryboardSegue parameter:

Objective-C:

- (IBAction)unwindToRed:(UIStoryboardSegue *)unwindSegue
{
    UIViewController* sourceViewController = unwindSegue.sourceViewController;

    if ([sourceViewController isKindOfClass:[BlueViewController class]])
    {
        NSLog(@"Coming from BLUE!");
    }
    else if ([sourceViewController isKindOfClass:[GreenViewController class]])
    {
        NSLog(@"Coming from GREEN!");
    }
}

Swift:

@IBAction func unwindToRed(unwindSegue: UIStoryboardSegue) {
    if let blueViewController = unwindSegue.sourceViewController as? BlueViewController {
        println("Coming from BLUE")
    }
    else if let redViewController = unwindSegue.sourceViewController as? RedViewController {
        println("Coming from RED")
    }
}

Unwinding also works through a combination of push/modal segues. E.g. if I added another Yellow view controller with a modal segue, we could unwind from Yellow all the way back to Red in a single step:

Unwinding from Code

When you define an unwind segue by control-dragging something to the Exit symbol of a view controller, a new segue appears in the Document Outline:

Selecting the segue and going to the Attributes Inspector reveals the "Identifier" property. Use this to give a unique identifier to your segue:

After this, the unwind segue can be performed from code just like any other segue:

Objective-C:

[self performSegueWithIdentifier:@"UnwindToRedSegueID" sender:self];

Swift:

performSegueWithIdentifier("UnwindToRedSegueID", sender: self)

collect_set can help to get unique values from a given column of pyspark.sql.DataFrame df.select(F.collect_set("column").alias("column")).first()["column"]

I believe the main benefit of using the literal form (ie, "foo" rather than new String("foo")) is that all String literals are 'interned' by the VM. In other words it is added to a pool such that any other code that creates the same string will use the pooled String rather than creating a new instance.

To illustrate, the following code will print true for the first line, but false for the second:

System.out.println("foo" == "foo");
System.out.println(new String("bar") == new String("bar"));

If you are already using ExtJS in your project you could use Ext.Date:

var date = new Date();
Ext.Date.format(date, "d-M-Y");

returns:

"11-Nov-2015"

try this

SimpleDateFormat dateFormat = new SimpleDateFormat("dd-MM-yyyy HH:mm:ss");
String string  = dateFormat.format(new Date());
System.out.println(string);

you can create any format see this

I know this is an old post however thought I'd throw my simple solution into the mix since no one has suggested it.

I use the current directory to determine the current environment then flip the connection string and environment variable. This works great so long as you have a naming convention for your site folders such as test/beta/sandbox.

    protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
    {
        var dir = Environment.CurrentDirectory;
        string connectionString;

        if (dir.Contains("test", StringComparison.OrdinalIgnoreCase))
        {
            connectionString = new ConnectionStringBuilder(server: "xxx", database: "xxx").ConnectionString;
            Environment.SetEnvironmentVariable("ASPNETCORE_ENVIRONMENT", "Development");
        }
        else
        {
            connectionString = new ConnectionStringBuilder(server: "xxx", database: "xxx").ConnectionString;
            Environment.SetEnvironmentVariable("ASPNETCORE_ENVIRONMENT", "Production");
        }

        optionsBuilder.UseSqlServer(connectionString);
        optionsBuilder.UseLazyLoadingProxies();
        optionsBuilder.EnableSensitiveDataLogging();
    }

The thing is that .replace() does not modify the string itself, so you should write something like:

strInputString = strInputString.replace(...

It also seems like you're not doing character escaping correctly. The following worked for me:

strInputString = strInputString.replace(/'/g, "\\'");

You could try this notattion:

SELECT * from table1,table2 

More complicated one :

SELECT table1.field1,table1.field2, table2.field3,table2.field8 from table1,table2 where table1.field2 = something and table2.field3 = somethingelse

Are you using the HTML5 required attribute?

That will cause Chrome 10 to display a balloon prompting the user to fill out the field.

You can also define these chars as list of string. Then you can check if the characters is valid for accepted characters with list.Contains(x) method.

I understand the demands. The thing is, there are WPF Methods for getting those values - but yes, one of the contributors is right, not directly. The Solution is not to get all those workarounds, but to change the initial approach according to clean Design and Development.

A) Set the initial Main Window to Screen

B) Get the Values for the ActualWindow including a ton of useful WPF Methods

C) You can add as many Windows as you like for the behaviour you want to have, like resizeable, minimized whatever… but now you always can access the Loaded and Rendered Screen

Please be careful with the following example, there is some Code around that makes it necessary to use that kind of approach, however it should work (It would give you the Points for each of the Corners of your Screen): Working Example on Single, Dual Monitor and different Resolutions (Within the Primal Main Window Class):

InitializeComponent();
[…]
ActualWindow.AddHandler(Window.LoadedEvent, new RoutedEventHandler(StartUpScreenLoaded));

Routed Event:

private void StartUpScreenLoaded(object sender, RoutedEventArgs e)
    {
        Window StartUpScreen = sender as Window;

        // Dispatcher Format B:
        Dispatcher.Invoke(new Action(() =>
        {
            // Get Actual Window on Loaded
            StartUpScreen.InvalidateVisual();
            System.Windows.Point CoordinatesTopRight = StartUpScreen.TranslatePoint(new System.Windows.Point((StartUpScreen.ActualWidth), (0d)), ActualWindow);
            System.Windows.Point CoordinatesBottomRight = StartUpScreen.TranslatePoint(new System.Windows.Point((StartUpScreen.ActualWidth), (StartUpScreen.ActualHeight)), ActualWindow);
            System.Windows.Point CoordinatesBottomLeft = StartUpScreen.TranslatePoint(new System.Windows.Point((0d), (StartUpScreen.ActualHeight)), ActualWindow);

            // Set the Canvas Top Right, Bottom Right, Bottom Left Coordinates
            System.Windows.Application.Current.Resources["StartUpScreenPointTopRight"] = CoordinatesTopRight;
            System.Windows.Application.Current.Resources["StartUpScreenPointBottomRight"] = CoordinatesBottomRight;
            System.Windows.Application.Current.Resources["StartUpScreenPointBottomLeft"] = CoordinatesBottomLeft;
        }), DispatcherPriority.Loaded);
    }

It has really different usage scenarios. When you use GROUP BY you merge some of the records for the columns that are same and you have an aggregation of the result set.

However when you use PARTITION BY your result set is same but you just have an aggregation over the window functions and you don't merge the records, you will still have the same count of records.

Here is a rally helpful article explaining the difference: http://alevryustemov.com/sql/sql-partition-by/

Building on @boulder_ruby's answer, this is what I'm looking for, assuming us_eco contains the CSV table as from my gist.

CSV.open('outfile.txt','wb', col_sep: "\t") do |csvfile|
  csvfile << us_eco.first.keys
  us_eco.each do |row|
    csvfile << row.values
  end
end

Updated the gist at https://gist.github.com/tamouse/4647196

If you still want to create date using dashes, you can use this format:

var date = new Date('2013-08-31T17:00:00Z')

But bear in mind, that it creates time according to UTC. Meaning, if you live in GMT+3 (3 hours ahead of GMT) timezone, it will add this timezone offset to the time. So the above example will have this value, if GMT+3 (note that it is hour 20:00 and not 17:00):

Sat Aug 31 2013 20:00:00 GMT+0300 (FLE Standard Time)

Be sure to add 'Z' letter at the end, because otherwise Chrome and Firefox will parse the string differently (one will add time offset and the other won't).

app.use(path, middleware) is used to call middleware function that needs to be called before the route is hit for the corresponding path. Multiple middleware functions can be invoked via an app.use.

app.use(‘/fetch’, enforceAuthentication) -> enforceAuthentication middleware fn will be called when a request starting with ‘/fetch’ is received. It can be /fetch/users, /fetch/ids/{id}, etc

Some middleware functions might have to be called irrespective of the request. For such cases, a path is not specified, and since the the path defaults to / and every request starts with /, this middleware function will be called for all requests.

app.use(() => { // Initialize a common service })

next() fn needs to be called within each middleware function when multiple middleware functions are passed to app.use, else the next middleware function won’t be called.

reference : http://expressjs.com/en/api.html#app.use

Note: The documentation says we can bypass middleware functions following the current one by calling next('route') within the current middleware function, but this technique didn't work for me within app.use but did work with app.METHOD like below. So, fn1 and fn2 were called but not fn3.

app.get('/fetch', function fn1(req, res, next)  {
    console.log("First middleware function called"); 
        next();
    }, 
    function fn2(req, res, next) {
        console.log("Second middleware function called"); 
        next("route");
    }, 
    function fn3(req, res, next) {
        console.log("Third middleware function will not be called"); 
        next();
    })

I managed to solve this issue with this call

Properties props = PropertiesUtil.loadProperties("whatever.properties");

Extra, you have to put your whatever.properties file in /src/main/resources

Try

CASE WHEN ebv.db_no IN (22978,23218,23219) THEN 'WECS 9500' ELSE 'WECS 9520' END

In order to represent a single digit in the form of a regular expression you can use either:

[0-9] or \d

In order to specify how many times the number appears you would add

[0-9]*: the star means there are zero or more digits

[0-9]{2}: {N} means N digits

[0-9]{0,2}: {N,M} N digits or M digits

[0-9]{0-9}: {N-M} N digits to M digits. Note: M can be left blank for an infinite representation

Lets say I want to represent a number between 1 and 99 I would express it as such:

[0-9]{1-2} or [0-9]{1,2} or \d{1-2} or \d{1,2}

Or lets say we were working with binary display, displaying a byte size, we would want our digits to be between 0 and 1 and length of a byte size, 8, so we would represent it as follows:

[0-1]{8} representation of a binary byte

Then if you want to add a , or a . symbol you would use:

\, or \. or you can use [.] or [,]

You can also state a selection between possible values as such

[.,] means either a dot or a comma symbol

And you just need to concatenate the pieces together, so in the case where you want to represent a 1 or 2 digit number followed by either a comma or a period and followed by two more digits you would express it as follows: >

[0-9]{1,2}[.,]\d{1-2}

Also note that regular expression strings inside C++ strings must be double-back-slashed so every \ becomes \\

If you need to send the FULL model to the controller, you first need the model to be available to your javascript code.

In our app, we do this with an extension method:

public static class JsonExtensions
{
    public static string ToJson(this Object obj)
    {
        return new JavaScriptSerializer().Serialize(obj);
    }
}

On the view, we use it to render the model:

<script type="javascript">
  var model = <%= Model.ToJson() %>
</script>

You can then pass the model variable into your $.ajax call.

This has been answered for the most part, but I will expand...

Step 1

My goal was to enable zoom at certain times, and disable it at others.

// enable pinch zoom
var $viewport = $('head meta[name="viewport"]');    
$viewport.attr('content', 'width=device-width, initial-scale=1, maximum-scale=4');

// ...later...

// disable pinch zoom
$viewport.attr('content', 'width=device-width, initial-scale=1, maximum-scale=1, user-scalable=no');

Step 2

The viewport tag would update, but pinch zoom was still active!! I had to find a way to get the page to pick up the changes...

It's a hack solution, but toggling the opacity of body did the trick. I'm sure there are other ways to accomplish this, but here's what worked for me.

// after updating viewport tag, force the page to pick up changes           
document.body.style.opacity = .9999;
setTimeout(function(){
    document.body.style.opacity = 1;
}, 1);

Step 3

My problem was mostly solved at this point, but not quite. I needed to know the current zoom level of the page so I could resize some elements to fit on the page (think of map markers).

// check zoom level during user interaction, or on animation frame
var currentZoom = $document.width() / window.innerWidth;

I hope this helps somebody. I spent several hours banging my mouse before finding a solution.

MySql decimal types are a little bit more complicated than just left-of and right-of the decimal point.

The first argument is precision, which is the number of total digits. The second argument is scale which is the maximum number of digits to the right of the decimal point.

Thus, (4,2) can be anything from -99.99 to 99.99.

As for why you're getting 99.99 instead of the desired 3.80, the value you're inserting must be interpreted as larger than 99.99, so the max value is used. Maybe you could post the code that you are using to insert or update the table.

Edit

Corrected a misunderstanding of the usage of scale and precision, per http://dev.mysql.com/doc/refman/5.0/en/numeric-types.html.

Just for the reason of documentation:

I have now (2014) observed that from all these valuable and correct approaches only one was successful. I've added a function to the WSDL on the server, and the client wasn't recognizing the new function.

• Adding WSDL_CACHE_NONE to the parameters didn't help.
• Adding the cache-buster didn't help.
• Setting soap.wsdl_cache_enabled to the PHP ini helped.

I am now unsure if it is the combination of all three, or if some features are terribly implemented so they may remain useless randomly, or if there is some hierarchy of features not understood.

So finally, expect that you have to check all three to solve problems like these.

Add another option, maybe not the most lightweight.

1. Use an online code highlighter like http://tohtml.com/ to highlight your code so you can paste marked up code from your IDE into Word. Depending on your IDE you may be able to skip this step.

2. In Word 2010, go to insert->object->openDocument Text. Steps 2-3 are documented at How do you display code snippets in MS Word preserving format and syntax highlighting?.

3. Paste your highlighted code into the object.

4. Copy the whole object.

5. Right-click-> paste special the object into Outlook.

This gives you a highlighted, contained box of code for use in emails in Outlook 2010.

Grid.mongo = mongo;

router.post('/:id', upload.array('photos', 200), function(req, res, next){
gfs = Grid(db);
var ss = req.files;
   for(var j=0; j<ss.length; j++){
     var originalName = ss[j].originalname;
     var filename = ss[j].filename;
     var writestream = gfs.createWriteStream({
         filename: originalName
     });
    fs.createReadStream("./uploads/" + filename).pipe(writestream);
   }
});

In your view:

<form action="/" method="post" enctype="multipart/form-data">
<input type="file" name="photos">

With this code you can add single as well as multiple images in MongoDB.

I struggled with this for a while and implemented the PL/SQL solution, but later realized that in Toad you can simply double click on the results grid cell, and it brings up an editor with contents in text. (i'm on Toad v11)

Building on Jared's answer, I had to enable and implement the action bar back button behavior in several activities and created this helper class to reduce code duplication.

public final class ActionBarHelper {
    public static void enableBackButton(AppCompatActivity context) {
        if(context == null) return;

        ActionBar actionBar = context.getSupportActionBar();
        if (actionBar == null) return;

        actionBar.setDisplayHomeAsUpEnabled(true);
    }
}

Usage in an activity:

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

    ActionBarHelper.enableBackButton(this);
}

2014-12-01 Update: The answer below works only for one very specific format of CSV. As correctly pointed out by DG in the comments, this solution does not fit the RFC 4180 definition of CSV and it also does not fit Microsoft Excel format. This solution simply demonstrates how one can parse one (non-standard) CSV line of input which contains a mix of string types, where the strings may contain escaped quotes and commas.

A non-standard CSV solution

As austincheney correctly points out, you really need to parse the string from start to finish if you wish to properly handle quoted strings that may contain escaped characters. Also, the OP does not clearly define what a "CSV string" really is. First we must define what constitutes a valid CSV string and its individual values.

Given: "CSV String" Definition

For the purpose of this discussion, a "CSV string" consists of zero or more values, where multiple values are separated by a comma. Each value may consist of:

1. A double quoted string (may contain unescaped single quotes).
2. A single quoted string (may contain unescaped double quotes).
3. A non-quoted string (may not contain quotes, commas or backslashes).
4. An empty value. (An all whitespace value is considered empty.)

Rules/Notes:

• Quoted values may contain commas.
• Quoted values may contain escaped-anything, e.g. 'that\'s cool'.
• Values containing quotes, commas, or backslashes must be quoted.
• Values containing leading or trailing whitespace must be quoted.
• The backslash is removed from all: \' in single quoted values.
• The backslash is removed from all: \" in double quoted values.
• Non-quoted strings are trimmed of any leading and trailing spaces.
• The comma separator may have adjacent whitespace (which is ignored).

Find:

A JavaScript function which converts a valid CSV string (as defined above) into an array of string values.

Solution:

The regular expressions used by this solution are complex. And (IMHO) all non-trivial regular expressions should be presented in free-spacing mode with lots of comments and indentation. Unfortunately, JavaScript does not allow free-spacing mode. Thus, the regular expressions implemented by this solution are first presented in native regular expressions syntax (expressed using Python's handy r'''...''' raw-multi-line-string syntax).

First here is a regular expression which validates that a CVS string meets the above requirements:

Regular expression to validate a "CSV string":

re_valid = r"""
# Validate a CSV string having single, double or un-quoted values.
^                                   # Anchor to start of string.
\s*                                 # Allow whitespace before value.
(?:                                 # Group for value alternatives.
  '[^'\\]*(?:\\[\S\s][^'\\]*)*'     # Either Single quoted string,
| "[^"\\]*(?:\\[\S\s][^"\\]*)*"     # or Double quoted string,
| [^,'"\s\\]*(?:\s+[^,'"\s\\]+)*    # or Non-comma, non-quote stuff.
)                                   # End group of value alternatives.
\s*                                 # Allow whitespace after value.
(?:                                 # Zero or more additional values
  ,                                 # Values separated by a comma.
  \s*                               # Allow whitespace before value.
  (?:                               # Group for value alternatives.
    '[^'\\]*(?:\\[\S\s][^'\\]*)*'   # Either Single quoted string,
  | "[^"\\]*(?:\\[\S\s][^"\\]*)*"   # or Double quoted string,
  | [^,'"\s\\]*(?:\s+[^,'"\s\\]+)*  # or Non-comma, non-quote stuff.
  )                                 # End group of value alternatives.
  \s*                               # Allow whitespace after value.
)*                                  # Zero or more additional values
$                                   # Anchor to end of string.
"""

If a string matches the above regular expression, then that string is a valid CSV string (according to the rules previously stated) and may be parsed using the following regular expression. The following regular expression is then used to match one value from the CSV string. It is applied repeatedly until no more matches are found (and all values have been parsed).

Regular expression to parse one value from a valid CSV string:

re_value = r"""
# Match one value in valid CSV string.
(?!\s*$)                            # Don't match empty last value.
\s*                                 # Strip whitespace before value.
(?:                                 # Group for value alternatives.
  '([^'\\]*(?:\\[\S\s][^'\\]*)*)'   # Either $1: Single quoted string,
| "([^"\\]*(?:\\[\S\s][^"\\]*)*)"   # or $2: Double quoted string,
| ([^,'"\s\\]*(?:\s+[^,'"\s\\]+)*)  # or $3: Non-comma, non-quote stuff.
)                                   # End group of value alternatives.
\s*                                 # Strip whitespace after value.
(?:,|$)                             # Field ends on comma or EOS.
"""

Note that there is one special case value that this regular expression does not match - the very last value when that value is empty. This special "empty last value" case is tested for and handled by the JavaScript function which follows.

JavaScript function to parse CSV string:

// Return array of string values, or NULL if CSV string not well formed.
function CSVtoArray(text) {
    var re_valid = /^\s*(?:'[^'\\]*(?:\\[\S\s][^'\\]*)*'|"[^"\\]*(?:\\[\S\s][^"\\]*)*"|[^,'"\s\\]*(?:\s+[^,'"\s\\]+)*)\s*(?:,\s*(?:'[^'\\]*(?:\\[\S\s][^'\\]*)*'|"[^"\\]*(?:\\[\S\s][^"\\]*)*"|[^,'"\s\\]*(?:\s+[^,'"\s\\]+)*)\s*)*$/;
    var re_value = /(?!\s*$)\s*(?:'([^'\\]*(?:\\[\S\s][^'\\]*)*)'|"([^"\\]*(?:\\[\S\s][^"\\]*)*)"|([^,'"\s\\]*(?:\s+[^,'"\s\\]+)*))\s*(?:,|$)/g;

    // Return NULL if input string is not well formed CSV string.
    if (!re_valid.test(text)) return null;

    var a = []; // Initialize array to receive values.
    text.replace(re_value, // "Walk" the string using replace with callback.
        function(m0, m1, m2, m3) {

            // Remove backslash from \' in single quoted values.
            if (m1 !== undefined) a.push(m1.replace(/\\'/g, "'"));

            // Remove backslash from \" in double quoted values.
            else if (m2 !== undefined) a.push(m2.replace(/\\"/g, '"'));
            else if (m3 !== undefined) a.push(m3);
            return ''; // Return empty string.
        });

    // Handle special case of empty last value.
    if (/,\s*$/.test(text)) a.push('');
    return a;
};

Example input and output:

In the following examples, curly braces are used to delimit the {result strings}. (This is to help visualize leading/trailing spaces and zero-length strings.)

// Test 1: Test string from original question.
var test = "'string, duppi, du', 23, lala";
var a = CSVtoArray(test);
/* Array has three elements:
    a[0] = {string, duppi, du}
    a[1] = {23}
    a[2] = {lala} */

// Test 2: Empty CSV string.
var test = "";
var a = CSVtoArray(test);
/* Array has zero elements: */

// Test 3: CSV string with two empty values.
var test = ",";
var a = CSVtoArray(test);
/* Array has two elements:
    a[0] = {}
    a[1] = {} */

// Test 4: Double quoted CSV string having single quoted values.
var test = "'one','two with escaped \' single quote', 'three, with, commas'";
var a = CSVtoArray(test);
/* Array has three elements:
    a[0] = {one}
    a[1] = {two with escaped ' single quote}
    a[2] = {three, with, commas} */

// Test 5: Single quoted CSV string having double quoted values.
var test = '"one","two with escaped \" double quote", "three, with, commas"';
var a = CSVtoArray(test);
/* Array has three elements:
    a[0] = {one}
    a[1] = {two with escaped " double quote}
    a[2] = {three, with, commas} */

// Test 6: CSV string with whitespace in and around empty and non-empty values.
var test = "   one  ,  'two'  ,  , ' four' ,, 'six ', ' seven ' ,  ";
var a = CSVtoArray(test);
/* Array has eight elements:
    a[0] = {one}
    a[1] = {two}
    a[2] = {}
    a[3] = { four}
    a[4] = {}
    a[5] = {six }
    a[6] = { seven }
    a[7] = {} */

Additional notes:

This solution requires that the CSV string be "valid". For example, unquoted values may not contain backslashes or quotes, e.g. the following CSV string is not valid:

var invalid1 = "one, that's me!, escaped \, comma"

This is not really a limitation because any sub-string may be represented as either a single or double quoted value. Note also that this solution represents only one possible definition for "comma-separated values".

you just need FileInfo -> CreationTime

and than just calculate the time difference.

in the app.config you can save the TimeSpan value of how old the file must be to be deleted

also check out the DateTime Subtract method.

good luck

I hope this comment will help you to find out your local & server file path using terminal

 find "$(cd ..; pwd)" -name "filename"

Or just you want to see your Current location then run

 pwd "filename"

Add below event to DateTimePicker

Private Sub DateTimePicker1_KeyPress(sender As Object, e As KeyPressEventArgs) Handles DateTimePicker1.KeyPress
    e.Handled = True
End Sub

If you are using TCHAR.H routine (implicitly, or explicitly), be sure you use _ttoi() function, so that it compiles for both Unicode and ANSI compilations.

You can do it with DOCTYPE, but you have to use table. Check this out:

Rather than grouping by visibility or by type of item (field, property, method, etc.), how about grouping by functionality?

It seems to me the last line of your example code should simply be:

Task<Item> itsMe = o as Task<Item>;

Or am I missing something?

Just to elaborate on Bhavin's excellent answer - editing the solution file works but you may still get the incompatible error (as David reported) if you had .NET 4.5 selected as the default .NET version in your VS2012 project and your VS2010 enviroment doesn't support that.

To quickly fix that, open the VS2012 .csproj file in a text editor and change the TargetFrameworkVersion down to 4.0 (from 4.5). VS2010 will then happily load the "edited" solution and projects.

You'll also have to edit an app.config files that have references to .NET 4.5 in a similar way to allow them to run on a .NET 4.0 environment.

I would use

WHERE columnName LIKE '%[%]%'

SQL Server stores string summary statistics for use in estimating the number of rows that will match a LIKE clause. The cardinality estimates can be better and lead to a more appropriate plan when the square bracket syntax is used.

The response to this Connect Item states

We do not have support for precise cardinality estimation in the presence of user defined escape characters. So we probably get a poor estimate and a poor plan. We'll consider addressing this issue in a future release.

An example

CREATE TABLE T
(
X VARCHAR(50),
Y CHAR(2000) NULL
)

CREATE NONCLUSTERED INDEX IX ON T(X)

INSERT INTO T (X)
SELECT TOP (5) '10% off'
FROM master..spt_values
UNION ALL
SELECT  TOP (100000)  'blah'
FROM master..spt_values v1,  master..spt_values v2


SET STATISTICS IO ON;
SELECT *
FROM T 
WHERE X LIKE '%[%]%'

SELECT *
FROM T
WHERE X LIKE '%\%%' ESCAPE '\'

Shows 457 logical reads for the first query and 33,335 for the second.

I was not able to get the createReadStream/createWriteStream method working for some reason, but using the fs-extra npm module it worked right away. I am not sure of the performance difference though.

npm install --save fs-extra

var fs = require('fs-extra');

fs.copySync(path.resolve(__dirname, './init/xxx.json'), 'xxx.json');

Sometimes, this error pops up because of the kernel has reached its limit. Try to restart the kernel redo the necessary steps.

You could extend the Application class and tag on any objects you want there, they are then available anywhere in your application

Yes, a struct is identical to a class except for the default access level (member-wise and inheritance-wise). (and the extra meaning class carries when used with a template)

Every functionality supported by a class is consequently supported by a struct. You'd use methods the same as you'd use them for a class.

struct foo {
  int bar;
  foo() : bar(3) {}   //look, a constructor
  int getBar() 
  { 
    return bar; 
  }
};

foo f;
int y = f.getBar(); // y is 3

and if you want to check div has a perticular children(say <p> use:

if ($('#myfav').children('p').length > 0) {
     // do something
}

Set<String> mySet = Collections.newSetFromMap(new ConcurrentHashMap<String, Boolean>());

• Saved the "vs_professional.exe" in my user Download directory, didn't work in any other disk or path.
• Installed the certificate, without the reboot.

Never thought MS could distribute this way, I understand that people downloading Visual Studio should have advanced knowledge of computers and OS but this is like a jump in time to 30 years back.

What's better, depends on your particular situation. One of the reasons out exists is to facilitate returning multiple values from one method call:

public int ReturnMultiple(int input, out int output1, out int output2)
{
    output1 = input + 1;
    output2 = input + 2;

    return input;
}

So one is not by definition better than the other. But usually you'd want to use a simple return, unless you have the above situation for example.

EDIT: This is a sample demonstrating one of the reasons that the keyword exists. The above is in no way to be considered a best practise.

I suddenly experienced this error, and the solution for me was to disable to run tests in parallel.

Your milage may vary, since I could lower number of failing tests by configuring surefire to run parallel tests by ´classes´.:

            <plugin>
                <artifactId>maven-surefire-plugin</artifactId>
                <version>2.22.2</version>
                <configuration>
                    <parallel>classes</parallel>
                    <threadCount>10</threadCount>
                </configuration>
            </plugin>

As I wrote first, this was not enough for my test suite, so I completely disabled parallel by removing the <configuration> section.

It's best practice to use COPY instead of ADD when you're copying from the local file system to the image. Also, I'd recommend creating a sub-folder to place your content into. If nothing else, it keeps things tidy. Make sure you mark the script as executable using chmod.

Here, I am creating a scripts sub-folder to place my script into and run it from:

RUN mkdir -p /scripts
COPY script.sh /scripts
WORKDIR /scripts
RUN chmod +x script.sh
RUN script.sh

SELECT * INTO < new_table > FROM < existing_table > WHERE < clause >

% is modulo. 3 % 2 = 1, 4 % 2 = 0

/ is (an integer in this case) division, so:

3 + 2 + 1 - 5 + 4 % 2 - 1 / 4 + 6
1 + 4%2 - 1/4 + 6
1 + 0 - 0 + 6
7

If you have a List of type string that you want in a drop down list I do the following:

EDIT: Clarified, making it a fuller example.

public class ShipDirectory
{
    public string ShipDirectoryName { get; set; }
    public List<string> ShipNames { get; set; }
}

ShipDirectory myShipDirectory = new ShipDirectory()
{
    ShipDirectoryName = "Incomming Vessels",
    ShipNames = new List<string>(){"A", "A B"},
}

myShipDirectory.ShipNames.Add("Aunt Bessy");

@Html.DropDownListFor(x => x.ShipNames, new SelectList(Model.ShipNames), "Select a Ship...", new { @style = "width:500px" })

Which gives a drop down list like so:

<select id="ShipNames" name="ShipNames" style="width:500px">
    <option value="">Select a Ship...</option>
    <option>A</option>
    <option>A B</option>
    <option>Aunt Bessy</option>
</select>

To get the value on a controllers post; if you are using a model (e.g. MyViewModel) that has the List of strings as a property, because you have specified x => x.ShipNames you simply have the method signature as (because it will be serialised/deserialsed within the model):

public ActionResult MyActionName(MyViewModel model)

Access the ShipNames value like so: model.ShipNames

If you just want to access the drop down list on post then the signature becomes:

public ActionResult MyActionName(string ShipNames)

EDIT: In accordance with comments have clarified how to access the ShipNames property in the model collection parameter.

If you want to table do following steps:-

views.py:

def view_info(request):
    objs=Model_name.objects.all()
    ............
    return render(request,'template_name',{'objs':obj})

.html page

 {% for item in objs %}
    <tr> 
         <td>{{ item.field1 }}</td>
         <td>{{ item.field2 }}</td>
         <td>{{ item.field3 }}</td>
         <td>{{ item.field4 }}</td>
    </tr>
       {% endfor %}

var page = "http://somurl.com/asom.php.aspx";

var $dialog = $('<div></div>')
               .html('<iframe style="border: 0px; " src="' + page + '" width="100%" height="100%"></iframe>')
               .dialog({
                   autoOpen: false,
                   modal: true,
                   height: 625,
                   width: 500,
                   title: "Some title"
               });
$dialog.dialog('open');

Use this inside a function. This is great if you really want to load an external URL as an IFRAME. Also make sure that in you custom jqueryUI you have the dialog.

This should answer that question, and then some.

The second line, if (obj.GetType() == typeof(ClassA)) {}, is faster, for those that don't want to read the article.

(Be aware that they don't do the same thing)

EDIT: Handlebars now has a built-in way of accomplishing this; see the selected answer above. When working with plain Mustache, the below still applies.

Mustache can iterate over items in an array. So I'd suggest creating a separate data object formatted in a way Mustache can work with:

var o = {
  bob : 'For sure',
  roger: 'Unknown',
  donkey: 'What an ass'
},
mustacheFormattedData = { 'people' : [] };

for (var prop in o){
  if (o.hasOwnProperty(prop)){
    mustacheFormattedData['people'].push({
      'key' : prop,
      'value' : o[prop]
     });
  }
}

Now, your Mustache template would be something like:

{{#people}}
  {{key}} : {{value}}
{{/people}}

Check out the "Non-Empty Lists" section here: https://github.com/janl/mustache.js

Alternative:

library(stringr)
a = c("capitalise this", "and this")
a
[1] "capitalise this" "and this"       
str_to_title(a)
[1] "Capitalise This" "And This"   

To remove message on logcat, i add a subtitle to track. On windows, right click on track -> Property -> Details -> insert a text on subtitle. Done :)

Loop through the Items and Add to the Collection. You can use the Add method

List<string>items=new List<string>();
using (var con= new SqlConnection("yourConnectionStringHere")
{
    string qry="SELECT Column1 FROM Table1";
    var cmd= new SqlCommand(qry, con);
    cmd.CommandType = CommandType.Text;
    con.Open();
    using (SqlDataReader objReader = cmd.ExecuteReader())
    {
        if (objReader.HasRows)
        {              
            while (objReader.Read())
            {
              //I would also check for DB.Null here before reading the value.
               string item= objReader.GetString(objReader.GetOrdinal("Column1"));
               items.Add(item);                  
            }
        }
    }
}

You have a method called getArguments() that belongs to Fragment class.

Whenever you face this issue, just define the web element once again above the line in which you are getting an Error.

Example:

WebElement button = driver.findElement(By.xpath("xpath"));
button.click();

//here you do something like update or save 

//then you try to use the button WebElement again to click 
button.click();

Since the DOM has changed e.g. through the update action, you are receiving a StaleElementReference Error.

Solution:

WebElement button = driver.findElement(By.xpath("xpath"));
button.click();

//here you do something like update or save 

//then you define the button element again before you use it
WebElement button1 = driver.findElement(By.xpath("xpath"));
//that new element will point to the same element in the new DOM
button1.click();

You forgot to print the result. What you get is the P in RE(P)L and not the actual printed result.

In Py2.x you should so something like

>>> print "\n".join(['I', 'would', 'expect', 'multiple', 'lines'])
I
would
expect
multiple
lines

and in Py3.X, print is a function, so you should do

print("\n".join(['I', 'would', 'expect', 'multiple', 'lines']))

Now that was the short answer. Your Python Interpreter, which is actually a REPL, always displays the representation of the string rather than the actual displayed output. Representation is what you would get with the repr statement

>>> print repr("\n".join(['I', 'would', 'expect', 'multiple', 'lines']))
'I\nwould\nexpect\nmultiple\nlines'

I just had this issue from a namespace mismatch. My XAML file was getting ported over and it had a different namespace from that in the code behind file.

i use like tim say sprintf('%0.6f', x), it's a string then i change it to number by using command str2double(x).

You can combine filter with the text.

You can use PdfBox from Apache which is simple to use and has good performance.

Here is an example of extracting text from a PDF file (you can read more here) :

import java.io.*;
import org.apache.pdfbox.pdmodel.*;
import org.apache.pdfbox.util.*;

public class PDFTest {

 public static void main(String[] args){
 PDDocument pd;
 BufferedWriter wr;
 try {
         File input = new File("C:\\Invoice.pdf");  // The PDF file from where you would like to extract
         File output = new File("C:\\SampleText.txt"); // The text file where you are going to store the extracted data
         pd = PDDocument.load(input);
         System.out.println(pd.getNumberOfPages());
         System.out.println(pd.isEncrypted());
         pd.save("CopyOfInvoice.pdf"); // Creates a copy called "CopyOfInvoice.pdf"
         PDFTextStripper stripper = new PDFTextStripper();
         wr = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(output)));
         stripper.writeText(pd, wr);
         if (pd != null) {
             pd.close();
         }
        // I use close() to flush the stream.
        wr.close();
 } catch (Exception e){
         e.printStackTrace();
        } 
     }
}

UPDATE:

You can get the text using PDFTextStripper:

PDFTextStripper reader = new PDFTextStripper();
String pageText = reader.getText(pd); // PDDocument object created

I found the other answers rather long and complicated, so I created this simple diagram to explain the way Python treats variables and parameters.

You have written three paths above. The first path (path to maven) should be pointing to the bin directory.

Path to Maven: C:\apache-maven-3.1.0\apache-maven-3.1.0\bin;

Below are right. Above path should be corrected.

M2_HOME:C:\apache-maven-3.1.0\apache-maven-3.1.0;

PATH: Other things,C:\Program Files (x86)\Java\jdk1.7.0_40\bin,C:\apache-maven-3.1.0\apache-maven-3.1.0\bin;

I'm sorry to disagree, but according to the rules for parsing a legacy color value posted by @Yuhong Bao, chucknorris DOES NOT equate to #CC0000, but rather to #C00000, a very similar but slightly different hue of red. I used the Firefox ColorZilla add-on to verify this.

The rules state:

• make the string a length that is a multiple of 3 by adding 0s: chucknorris0
• separate the string into 3 equal length strings: chuc knor ris0
• truncate each string to 2 characters: ch kn ri
• keep the hex values, and add 0's where necessary: C0 00 00

I was able to use these rules to correctly interpret the following strings:

• LuckyCharms
• Luck
• LuckBeALady
• LuckBeALadyTonight
• GangnamStyle

UPDATE: The original answerers who said the color was #CC0000 have since edited their answers to include the correction.

A commenter asked "why use a third-party library for this?" The answer is that it's way too much of a pain to do it yourself. Here's an example of how to properly do the inverse operation of reading a byte array from a file (sorry, this is just the code I had readily available, and it's not like I want the asker to actually paste and use this code anyway):

public static byte[] toByteArray(File file) throws IOException { 
   ByteArrayOutputStream out = new ByteArrayOutputStream(); 
   boolean threw = true; 
   InputStream in = new FileInputStream(file); 
   try { 
     byte[] buf = new byte[BUF_SIZE]; 
     long total = 0; 
     while (true) { 
       int r = in.read(buf); 
       if (r == -1) {
         break; 
       }
       out.write(buf, 0, r); 
     } 
     threw = false; 
   } finally { 
     try { 
       in.close(); 
     } catch (IOException e) { 
       if (threw) { 
         log.warn("IOException thrown while closing", e); 
       } else {
         throw e;
       } 
     } 
   } 
   return out.toByteArray(); 
 }

Everyone ought to be thoroughly appalled by what a pain that is.

Use Good Libraries. I, unsurprisingly, recommend Guava's Files.write(byte[], File).

Your model is @Messages, change it to @message.

To change it like you should use migration:

def change   rename_table :old_table_name, :new_table_name end 

Of course do not create that file by hand but use rails generator:

rails g migration ChangeMessagesToMessage 

That will generate new file with proper timestamp in name in 'db dir. Then run:

rake db:migrate 

And your app should be fine since then.

The most Pythonic way is to use the len(). Keep in mind that the '\' character in escape sequences is not counted and can be dangerous if not used correctly.

>>> len('foo')
3
>>> len('\foo')
3
>>> len('\xoo')
  File "<stdin>", line 1
SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 0-1: truncated \xXX escape

There is a simple work around. The alert only comes up when you have a large amount of data in your clipboard. Just copy a random cell before you close the workbook and it won't show up anymore!

In my case deleting bootstrap/cache fixed the problem

I would do this slightly different by applying both the UNPIVOT and the PIVOT functions to get the final result. The unpivot takes the values from both the totalcount and totalamount columns and places them into one column with multiple rows. You can then pivot on those results.:

select chardate,
  Australia_totalcount as [Australia # of Transactions], 
  Australia_totalamount as [Australia Total $ Amount],
  Austria_totalcount as [Austria # of Transactions], 
  Austria_totalamount as [Austria Total $ Amount]
from
(
  select 
    numericmonth, 
    chardate,
    country +'_'+col col, 
    value
  from
  (
    select numericmonth, 
      country, 
      chardate,
      cast(totalcount as numeric(10, 2)) totalcount,
      cast(totalamount as numeric(10, 2)) totalamount
    from mytransactions
  ) src
  unpivot
  (
    value
    for col in (totalcount, totalamount)
  ) unpiv
) s
pivot
(
  sum(value)
  for col in (Australia_totalcount, Australia_totalamount,
              Austria_totalcount, Austria_totalamount)
) piv
order by numericmonth

See SQL Fiddle with Demo.

If you have an unknown number of country names, then you can use dynamic SQL:

DECLARE @cols AS NVARCHAR(MAX),
    @colsName AS NVARCHAR(MAX),
    @query  AS NVARCHAR(MAX)

select @cols = STUFF((SELECT distinct ',' + QUOTENAME(country +'_'+c.col) 
                      from mytransactions
                      cross apply 
                      (
                        select 'TotalCount' col
                        union all
                        select 'TotalAmount'
                      ) c
            FOR XML PATH(''), TYPE
            ).value('.', 'NVARCHAR(MAX)') 
        ,1,1,'')

select @colsName 
    = STUFF((SELECT distinct ', ' + QUOTENAME(country +'_'+c.col) 
               +' as ['
               + country + case when c.col = 'TotalCount' then ' # of Transactions]' else 'Total $ Amount]' end
             from mytransactions
             cross apply 
             (
                select 'TotalCount' col
                union all
                select 'TotalAmount'
             ) c
            FOR XML PATH(''), TYPE
            ).value('.', 'NVARCHAR(MAX)') 
        ,1,1,'')

set @query 
  = 'SELECT chardate, ' + @colsName + ' 
     from 
     (
      select 
        numericmonth, 
        chardate,
        country +''_''+col col, 
        value
      from
      (
        select numericmonth,

          cast(totalamount as numeric(10, 2)) totalamount
        from mytransactions
      ) src
      unpivot
      (
        value
        for col in (totalcount, totalamount)
      ) unpiv
     ) s
     pivot 
     (
       sum(value)
       for col in (' + @cols + ')
     ) p 
     order by numericmonth'

execute(@query)

See SQL Fiddle with Demo

Both give the result:

You could use Clint:

In Urlmon.dll, there's a function called FindMimeFromData.

From the documentation

MIME type detection, or "data sniffing," refers to the process of determining an appropriate MIME type from binary data. The final result depends on a combination of server-supplied MIME type headers, file extension, and/or the data itself. Usually, only the first 256 bytes of data are significant.

So, read the first (up to) 256 bytes from the file and pass it to FindMimeFromData.

What about making a simple function?

function isEmptyObject(obj) {
  for(var prop in obj) {
    if (Object.prototype.hasOwnProperty.call(obj, prop)) {
      return false;
    }
  }
  return true;
}

isEmptyObject({}); // true
isEmptyObject({foo:'bar'});  // false

The hasOwnProperty method call directly on the Object.prototype is only to add little more safety, imagine the following using a normal obj.hasOwnProperty(...) call:

isEmptyObject({hasOwnProperty:'boom'});  // false

Note: _{(for the future)} The above method relies on the for...in statement, and this statement iterates only over enumerable properties, in the currently most widely implemented ECMAScript Standard (3rd edition) the programmer doesn't have any way to create non-enumerable properties.

However this has changed now with ECMAScript 5th Edition, and we are able to create non-enumerable, non-writable or non-deletable properties, so the above method can fail, e.g.:

var obj = {};
Object.defineProperty(obj, 'test', { value: 'testVal', 
  enumerable: false,
  writable: true,
  configurable: true
});
isEmptyObject(obj); // true, wrong!!
obj.hasOwnProperty('test'); // true, the property exist!!

An ECMAScript 5 solution to this problem would be:

function isEmptyObject(obj) {
  return Object.getOwnPropertyNames(obj).length === 0;
}

The Object.getOwnPropertyNames method returns an Array containing the names of all the own properties of an object, enumerable or not, this method is being implemented now by browser vendors, it's already on the Chrome 5 Beta and the latest WebKit Nightly Builds.

Object.defineProperty is also available on those browsers and latest Firefox 3.7 Alpha releases.

You'll have to actually USE jQuery to build the div, if you want to write maintainable or usable code.

//create a div
var $newDiv = $('<div>');

//set the id
$newDiv.attr("id","myId");

Put the command to execute the sql script into a batch file then run the below code

string batchFileName = @"c:\batosql.bat";
string sqlFileName = @"c:\MySqlScripts.sql";
Process proc = new Process();
proc.StartInfo.FileName = batchFileName;
proc.StartInfo.Arguments = sqlFileName;
proc.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
proc.StartInfo.ErrorDialog = false;
proc.StartInfo.WorkingDirectory = Path.GetDirectoryName(batchFileName);
proc.Start();
proc.WaitForExit();
if ( proc.ExitCode!= 0 )

in the batch file write something like this (sample for sql server)

osql -E -i %1

If you find yourself writing the above solution as often as I do then you could implement it as a generic:

public static int GetEnumEntries<T>() where T : struct, IConvertible 
{
    if (!typeof(T).IsEnum)
        throw new ArgumentException("T must be an enumerated type");

    return Enum.GetNames(typeof(T)).Length;
}

To change the encoding of your database:

1. Dump your database
2. Drop your database,
3. Create new database with the different encoding
4. Reload your data.

Make sure the client encoding is set correctly during all this.

To check whether select box has any values:

if( $('#fruit_name').has('option').length > 0 ) {

To check whether selected value is empty:

if( !$('#fruit_name').val() ) { 

I would use the SplFileObject class...

$file = new SplFileObject("filename");
if (!$file->eof()) {
     $file->seek($lineNumber);
     $contents = $file->current(); // $contents would hold the data from line x
}

Something like this.

function addRowHandlers() {
  var table = document.getElementById("tableId");
  var rows = table.getElementsByTagName("tr");
  for (i = 0; i < rows.length; i++) {
    var currentRow = table.rows[i];
    var createClickHandler = function(row) {
      return function() {
        var cell = row.getElementsByTagName("td")[0];
        var id = cell.innerHTML;
        alert("id:" + id);
      };
    };
    currentRow.onclick = createClickHandler(currentRow);
  }
}

EDIT

Working demo.

Just in case you are like me and the Id Field of the User Entity is an Int or something else other than a string,

using Microsoft.AspNet.Identity;

int userId = User.Identity.GetUserId<int>();

will do the trick

when(
  fooDao.getBar(
    any(Bazoo.class)
  )
).thenReturn(myFoo);

or (to avoid nulls):

when(
  fooDao.getBar(
    (Bazoo)notNull()
  )
).thenReturn(myFoo);

Your desideratum,map.contains(key), is scheduled for the draft standard C++2a. In 2017 it was implemented by gcc 9.2. It's also in the current clang.

I got the upload working with above changes. But when I made the changes I started getting 404 response in file upload which lead me to do further debugging and figured out its a permission issue by checking nginx error.log

Solution:

Check the current user and group ownership on /var/lib/nginx.

$ ls -ld /var/lib/nginx

drwx------. 3 nginx nginx 17 Oct 5 19:31 /var/lib/nginx

This tells that a possibly non-existent user and group named nginx owns this folder. This is preventing file uploading.

In my case, the username mentioned in "/etc/nginx/nginx.conf" was

user vagrant; 

Change the folder ownership to the user defined in nginx.conf in this case vagrant.

$ sudo chown -Rf vagrant:vagrant /var/lib/nginx

Verify that it actually changed.

$ ls -ld /var/lib/nginx
drwx------. 3 vagrant vagrant 17 Oct  5 19:31 /var/lib/nginx

Reload nginx and php-fpm for safer sade.

$ sudo service nginx reload
$ sudo service php-fpm reload

The permission denied error should now go away. Check the error.log (based on nginx.conf error_log location).

$ sudo nano /path/to/nginx/error.log

for your example:

{'profiles': [{'name':'john', 'age': 44}, {'name':'Alex','age':11}]}

you will have to do something of this effect:

JSONObject myjson = new JSONObject(the_json);
JSONArray the_json_array = myjson.getJSONArray("profiles");

this returns the array object.

Then iterating will be as follows:

    int size = the_json_array.length();
    ArrayList<JSONObject> arrays = new ArrayList<JSONObject>();
    for (int i = 0; i < size; i++) {
        JSONObject another_json_object = the_json_array.getJSONObject(i);
            //Blah blah blah...
            arrays.add(another_json_object);
    }

//Finally
JSONObject[] jsons = new JSONObject[arrays.size()];
arrays.toArray(jsons);

//The end...

You will have to determine if the data is an array (simply checking that charAt(0) starts with [ character).

Hope this helps.

I ran into this where the scripts would load once, but repeat calls would not run the script.

It turned out to be an issue with using .html() to display a wait indicator and then chaining .load() after it.

// Processes scripts as expected once per page load, but not for repeat calls
$("#id").html("<img src=wait.gif>").load("page.html");

When I made them separate calls, my inline scripts loaded every time as expected.

// Without chaining html and load together, scripts are processed as expected every time
$("#id").html("<img src=wait.gif>");
$("#id").load("page.html");

For further research, note that there are two versions of .load()

A simple .load() call (without a selector after the url) is simply a shorthand for calling $.ajax() with dataType:"html" and taking the return contents and calling .html() to put those contents in the DOM. And the documentation for dataType:"html" clearly states "included script tags are evaluated when inserted in the DOM." http://api.jquery.com/jquery.ajax/ So .load() officially runs inline scripts.

A complex .load() call has a selector such as load("page.html #content"). When used that way, jQuery purposefully filters out script tags as discussed in articles like this one: https://forum.jquery.com/topic/the-load-function-and-script-blocks#14737000000752785 In this case the scripts never run, not even once.

When a Stale Element Exception occurs!!

Stale element exception can happen when the libraries supporting those textboxes/ buttons/ links has changed which means the elements are same but the reference has now changed in the website without affecting the locators. Thus the reference which we stored in our cache including the library reference has now become old or stale because the page has been refreshed with updated libraries.

for(int j=0; j<5;j++)
try {
    WebElement elementName=driver.findElement(By.name(“createForm:dateInput_input”));
    break;
} catch(StaleElementReferenceException e){
e.toString();
System.out.println(“Stale element error, trying ::  ” + e.getMessage());
}
elementName.sendKeys(“20/06/2018”);

Is it your first android connected to your computer? Sometimes windows drivers need to be erased. Refer http://forum.xda-developers.com/showthread.php?t=2512549

using ScreenCaptureView class we can capture the iphone screen as video.The source code is available here.The recorded video is saved in a NSUrl,outputURL.Use that NSUrl in a method like below to play the recorded video,

    -(void)playvideo
{

  MPMoviePlayerController *player = [[MPMoviePlayerController alloc] initWithContentURL:outputURL ];
       [player.view setFrame:CGRectMake(0,0,320,480)];

[player setMovieControlMode:MPMovieControlModeHidden];   

[player setScalingMode:MPMovieScalingModeAspectFit];

 [player setBackgroundColor:[UIColor blackColor]];

 [player setFullscreen:YES animated:YES];

[player play];

[self addSubview:player.view];

}

call this method before releasing NSUrl in completeRecordingSession method ..it will replay what you did in the iphone screen as a video.

Since Android 4.2 (API 17) nested fragments become available http://developer.android.com/about/versions/android-4.2.html#NestedFragments

To place fragment inside other fragment use getChildFragmentManager()

It also available in support library!

Something like this.setExtendedState(this.getExtendedState() | this.MAXIMIZED_BOTH);

import java.awt.*;
import javax.swing.*;

public class Test extends JFrame
{
    public Test()
    {
        GraphicsEnvironment env =
GraphicsEnvironment.getLocalGraphicsEnvironment();
        this.setMaximizedBounds(env.getMaximumWindowBounds());
        this.setExtendedState(this.getExtendedState() | this.MAXIMIZED_BOTH);
    }

    public static void main(String[] args)
    {
        JFrame.setDefaultLookAndFeelDecorated(true);

        Test t = new Test();
        t.setVisible(true);
    }
}

using(SqlCommand cmd=new SqlCommand("INSERT INTO Mem_Basic(Mem_Na,Mem_Occ) " +
    "VALUES(@na,@occ);SELECT SCOPE_IDENTITY();",con))
{
    cmd.Parameters.AddWithValue("@na", Mem_NA);
    cmd.Parameters.AddWithValue("@occ", Mem_Occ);
    con.Open();

    int modified = cmd.ExecuteNonQuery();

    if (con.State == System.Data.ConnectionState.Open) con.Close();
        return modified;
}

SCOPE_IDENTITY : Returns the last identity value inserted into an identity column in the same scope. for more details http://technet.microsoft.com/en-us/library/ms190315.aspx

The DictWriter doesn't work the way you expect.

with open('dict.csv', 'w') as csv_file:  
    writer = csv.writer(csv_file)
    for key, value in mydict.items():
       writer.writerow([key, value])

To read it back:

with open('dict.csv') as csv_file:
    reader = csv.reader(csv_file)
    mydict = dict(reader)

which is quite compact, but it assumes you don't need to do any type conversion when reading

should use xargs :)

find *.txt -type f -exec tail -1 {} \; | xargs -ICONSTANT echo $(pwd),CONSTANT

another one (working on osx)

find *.txt -type f -exec echo ,$(PWD) {} + -exec tail -1 {} + | tr ' ' '/'
