The C99 way is

#include <inttypes.h>
int64_t my_int = 999999999999999999;
printf("%" PRId64 "\n", my_int);

Or you could cast!

printf("%ld", (long)my_int);
printf("%lld", (long long)my_int); /* C89 didn't define `long long` */
printf("%f", (double)my_int);

If you're stuck with a C89 implementation (notably Visual Studio) you can perhaps use an open source <inttypes.h> (and <stdint.h>): http://code.google.com/p/msinttypes/

You could try doing it through R:

For Stata <= 15 you can use the haven package to read the dataset and then you simply write it to external CSV file:

library(haven)
yourData = read_dta("path/to/file")
write.csv(yourData, file = "yourStataFile.csv")

Alternatively, visit the link pointed by huntaub in a comment below.

For Stata <= 12 datasets foreign package can also be used

library(foreign)
yourData <- read.dta("yourStataFile.dta")

math.sqrt is the C implementation of square root and is therefore different from using the ** operator which implements Python's built-in pow function. Thus, using math.sqrt actually gives a different answer than using the ** operator and there is indeed a computational reason to prefer numpy or math module implementation over the built-in. Specifically the sqrt functions are probably implemented in the most efficient way possible whereas ** operates over a large number of bases and exponents and is probably unoptimized for the specific case of square root. On the other hand, the built-in pow function handles a few extra cases like "complex numbers, unbounded integer powers, and modular exponentiation".

See this Stack Overflow question for more information on the difference between ** and math.sqrt.

In terms of which is more "Pythonic", I think we need to discuss the very definition of that word. From the official Python glossary, it states that a piece of code or idea is Pythonic if it "closely follows the most common idioms of the Python language, rather than implementing code using concepts common to other languages." In every single other language I can think of, there is some math module with basic square root functions. However there are languages that lack a power operator like ** e.g. C++. So ** is probably more Pythonic, but whether or not it's objectively better depends on the use case.

It worked like this for me:

document.getElementById("theElementID").setAttribute("src", source);
document.getElementById("task-text").innerHTML = "";

Change the

getElementById("theElementID")

for your element locator (name, css, xpath...)

As an appreciation for this thread, here is my little contribution with the implementation in Ruby, hoping that I will save someone a few minutes from their precious time:

def self.find_center(locations)

 number_of_locations = locations.length

 return locations.first if number_of_locations == 1

 x = y = z = 0.0
 locations.each do |station|
   latitude = station.latitude * Math::PI / 180
   longitude = station.longitude * Math::PI / 180

   x += Math.cos(latitude) * Math.cos(longitude)
   y += Math.cos(latitude) * Math.sin(longitude)
   z += Math.sin(latitude)
 end

 x = x/number_of_locations
 y = y/number_of_locations
 z = z/number_of_locations

 central_longitude =  Math.atan2(y, x)
 central_square_root = Math.sqrt(x * x + y * y)
 central_latitude = Math.atan2(z, central_square_root)

 [latitude: central_latitude * 180 / Math::PI, 
 longitude: central_longitude * 180 / Math::PI]
end

The following code assumes that your table has the ID 'MyTable'

<script language="JavaScript">
<!--
var oRows = document.getElementById('MyTable').getElementsByTagName('tr');
var iRowCount = oRows.length;

alert('Your table has ' + iRowCount + ' rows.');
//-->
</script>

Followed by @JeffH answer, I recommend to use typeof() than string assembly name.

    var rm = new ResourceManager(typeof(YourAssembly.Properties.Resources));
    string message = rm.GetString("NameOfKey", CultureInfo.CreateSpecificCulture("ja-JP"));

Another example is:

$(".myClass").on("click", function () {
   var $this = $(this);

   if ($this.hasClass("show") {
    $this.removeClass("show");
   } else {
    $this.addClass("show");
   }
});

I had a similar problem after upgrading to TF 2.0. The CUDA version that TF was reporting did not match what Ubuntu 18.04 thought I had installed. It said I was using CUDA 7.5.0, but apt thought I had the right version installed.

What I eventually had to do was grep recursively in /usr/local for CUDNN_MAJOR, and I found that /usr/local/cuda-10.0/targets/x86_64-linux/include/cudnn.h did indeed specify the version as 7.5.0.
/usr/local/cuda-10.1 got it right, and /usr/local/cuda pointed to /usr/local/cuda-10.1, so it was (and remains) a mystery to me why TF was looking at /usr/local/cuda-10.0.

Anyway, I just moved /usr/local/cuda-10.0 to /usr/local/old-cuda-10.0 so TF couldn't find it any more and everything then worked like a charm.

It was all very frustrating, and I still feel like I just did a random hack. But it worked :) and perhaps this will help someone with a similar issue.

If you hate numpy, get out RPy and your local copy of R, and use it instead.

(I would also echo to make you you really need to invert the matrix. In R, for example, linalg.solve and the solve() function don't actually do a full inversion, since it is unnecessary.)

1. Use conditional formatting instead of VBA to highlight errors.

2. Using a VBA loop like the one you posted will take a long time to process

3. the statement If cell.Value = "#N/A" Then will never work. If you insist on using VBA to highlight errors, try this instead.

   Sub ColorCells()

   Dim Data As Range
   Dim cell As Range
   Set currentsheet = ActiveWorkbook.Sheets("Comparison")
   Set Data = currentsheet.Range("A2:AW1048576")
   
   For Each cell In Data
   
   If IsError(cell.Value) Then
      cell.Interior.ColorIndex = 3
   End If
   Next
   
   End Sub
   

4. Be prepared for a long wait, since the procedure loops through 51 million cells

5. There are more efficient ways to achieve what you want to do. Update your question if you have a change of mind.

You'll want to use JavaScript's Array splice method:

var tag_story = [1,3,56,6,8,90],
    id_tag = 90,
    position = tag_story.indexOf(id_tag);

if ( ~position ) tag_story.splice(position, 1);

P.S. For an explanation of that cool ~ tilde shortcut, see this post:

Using a ~ tilde with indexOf to check for the existence of an item in an array.

Note: IE < 9 does not support .indexOf() on arrays. If you want to make sure your code works in IE, you should use jQuery's $.inArray():

var tag_story = [1,3,56,6,8,90],
    id_tag = 90,
    position = $.inArray(id_tag, tag_story);

if ( ~position ) tag_story.splice(position, 1);

If you want to support IE < 9 but don't already have jQuery on the page, there's no need to use it just for $.inArray. You can use this polyfill instead.

Could you please check if LD_LIBRARY_PATH points to the oracle libs

Your JAVA_HOME variable must be set to /usr/lib/jvm/java-6-openjdk and it must be available for the user that starts Jenkins.

From Kyle Strand comment:

As of April 2015 (I think), Jenkins requires Java7. Also note that the java binary path (JAVA) must be set to the correct version if the system default is still Java 6. Finally, for anyone wondering where these variables are set, it's in a config file listed with the installation instructions on the Jenkins webpage (e.g. for Debian it's /etc/default/jenkins).

In some situations we have to get image from drawable or raw folder using image name instead if generated id

// Image View Object 
        mIv = (ImageView) findViewById(R.id.xidIma);
// create context Object for  to Fetch  image from resourse 
Context mContext=getApplicationContext();

// getResources().getIdentifier("image_name","res_folder_name", package_name);

// find out below example 
    int i = mContext.getResources().getIdentifier("ic_launcher","raw", mContext.getPackageName());

// now we will get contsant id for that image       
        mIv.setBackgroundResource(i);

I've heard that using sudo with pip is unsafe.

Try adding --user to the end of your command, as mentioned here.

pip install packageName --user

I suspect that installing with this method means the packages are not available to other users.

Sync:

var fs = require('fs');
var obj = JSON.parse(fs.readFileSync('file', 'utf8'));

Async:

var fs = require('fs');
var obj;
fs.readFile('file', 'utf8', function (err, data) {
  if (err) throw err;
  obj = JSON.parse(data);
});

You can use the below:

public class HashmapKeyExist {
    public static void main(String[] args) {
        HashMap<String, String> hmap = new HashMap<String, String>();
        hmap.put("1", "Bala");
        hmap.put("2", "Test");

        Boolean cantain = hmap.containsValue("Bala");
        if(hmap.containsKey("2") && hmap.containsValue("Test"))
        {
            System.out.println("Yes");
        }
        if(cantain == true)
        {
            System.out.println("Yes"); 
        }

        Set setkeys = hmap.keySet();
        Iterator it = setkeys.iterator();

        while(it.hasNext())
        {
            String key = (String) it.next();
            if (hmap.get(key).equals("Bala"))
            {
                System.out.println(key);
            }
        }
    }
}

I used the code below, and it works

'PHONE' => 'required|regex:/(0)[0-9]/|not_regex:/[a-z]/|min:9',

In your Manifest you need to reference the name of the style that has the text color item inside it. Right now you are just referencing an empty style. So in your theme.xml do only this style:

<style name="Theme" parent="@android:style/TextAppearance">
    <item name="android:textColor">#ffffffff</item>
</style>

And keep you reference to in the Manifest the same (android:theme="@style/Theme")

EDIT:

theme.xml:

<style name="MyTheme" parent="@android:style/TextAppearance">
    <item name="android:textColor">#ffffffff</item>
    <item name="android:textSize">12dp</item>
</style>

Manifest:

<application
    android:icon="@drawable/icon"
    android:label="@string/app_name"
    android:theme="@style/MyTheme">

Notice I combine the text color and size into the same style. Also, I changed the name of the theme to MyTheme and am now referencing that in the Manifest. And I changed to @android:style/TextAppearance for the parent value.

ianhanniballake is right. You can get all the functionality of Activity from FragmentActivity. In fact, FragmentActivity has more functionality.

Using FragmentActivity you can easily build tab and swap format. For each tab you can use different Fragment (Fragments are reusable). So for any FragmentActivity you can reuse the same Fragment.

Still you can use Activity for single pages like list down something and edit element of the list in next page.

Also remember to use Activity if you are using android.app.Fragment; use FragmentActivity if you are using android.support.v4.app.Fragment. Never attach a android.support.v4.app.Fragment to an android.app.Activity, as this will cause an exception to be thrown.

Microsoft Excel Miniature, Quick-and-Dirty formula.

Hi,

Here's one way to get the Excel character-column-header from a number....

I created a formula for an Excel cell.

(i.e. I took the approach of not using VBA programming.)

The formula looks at a cell that has a number in it and tells you what the column is -- in letters.

In the attached image:

• I put 1,2,3 etc in the top row all the way out to column ABS.
• I pasted my formula in the second row all the way out to ABS.
• My formula looks at row 1 and converts the number to Excel's column header id.
• My formula works for all numbers out to 702 (zz).

• I did it in this manner to prove that the formula works so you can look at the output from the formula and look at the column header above and easily visually verify that the formula works. :-)

  =CONCATENATE(MID("_abcdefghijklmnopqrstuvwxyz",(IF(MOD(K1,26)>0,INT(K1/26)+1,(INT(K1/26)))),1),MID("abcdefghijklmnopqrstuvwxyz",IF(MOD(K1,26)=0,26,MOD(K1,26)),1))

The underscore was there for debugging purposes - to let you know there was an actual space and that it was working correctly.

With this formula above -- whatever you put in K1 - the formula will tell you what the column header will be.

The formula, in its current form, only goes out to 2 digits (ZZ) but could be modified to add the 3rd letter (ZZZ).

Im not a java developer but was using a java app to test a RESTful API. In order for me to fix the error I had to install the intermediate certificates in the webserver in order to make the error go away. I was using lighttpd, the original certificate was installed on an IIS server. Hope it helps. These were the certificates I had missing on the server.

• CA.crt
• UTNAddTrustServer_CA.crt
• AddTrustExternalCARoot.crt

It is not possible in on step or you need to keep the reference to the array. If you can change the reference this can help:

      String[] n = new String[]{"google","microsoft","apple"};
      final List<String> list =  new ArrayList<String>();
      Collections.addAll(list, n); 
      list.remove("apple");
      n = list.toArray(new String[list.size()]);

I not recommend the following but if you worry about performance:

      String[] n = new String[]{"google","microsoft","apple"};
      final String[] n2 = new String[2]; 
      System.arraycopy(n, 0, n2, 0, n2.length);
      for (int i = 0, j = 0; i < n.length; i++)
      {
        if (!n[i].equals("apple"))
        {
          n2[j] = n[i];
          j++;
        }      
      }

I not recommend it because the code is a lot more difficult to read and maintain.

• the object which implements Comparable is Fegan.

The method compareTo you are overidding in it should have a Fegan object as a parameter whereas you are casting it to a FoodItems. Your compareTo implementation should describe how a Fegan compare to another Fegan.

• To actually do your sorting, you might want to make your FoodItems implement Comparable aswell and copy paste your actual compareTo logic in it.

Summary

• You have an existing collection of records.
• You have a set records that contain updates to the existing records.
• Some of the updates don't really update anything, they duplicate what you have already.
• All updates contain the same fields that are there already, just possibly different values.
• You want to track when a record was last changed, where a value actually changed.

Note, I'm presuming PyMongo, change to suit your language of choice.

Instructions:

1. Create the collection with an index with unique=true so you don't get duplicate records.

2. Iterate over your input records, creating batches of them of 15,000 records or so. For each record in the batch, create a dict consisting of the data you want to insert, presuming each one is going to be a new record. Add the 'created' and 'updated' timestamps to these. Issue this as a batch insert command with the 'ContinueOnError' flag=true, so the insert of everything else happens even if there's a duplicate key in there (which it sounds like there will be). THIS WILL HAPPEN VERY FAST. Bulk inserts rock, I've gotten 15k/second performance levels. Further notes on ContinueOnError, see http://docs.mongodb.org/manual/core/write-operations/

   Record inserts happen VERY fast, so you'll be done with those inserts in no time. Now, it's time to update the relevant records. Do this with a batch retrieval, much faster than one at a time.

3. Iterate over all your input records again, creating batches of 15K or so. Extract out the keys (best if there's one key, but can't be helped if there isn't). Retrieve this bunch of records from Mongo with a db.collectionNameBlah.find({ field : { $in : [ 1, 2,3 ...}) query. For each of these records, determine if there's an update, and if so, issue the update, including updating the 'updated' timestamp.

   Unfortunately, we should note, MongoDB 2.4 and below do NOT include a bulk update operation. They're working on that.

Key Optimization Points:

• The inserts will vastly speed up your operations in bulk.
• Retrieving records en masse will speed things up, too.
• Individual updates are the only possible route now, but 10Gen is working on it. Presumably, this will be in 2.6, though I'm not sure if it will be finished by then, there's a lot of stuff to do (I've been following their Jira system).

pg_dump the_db_name > the_backup.sql

Then copy the backup to your development server, restore with:

psql the_new_dev_db < the_backup.sql

You are right, by creating object manually you are not letting Spring to perform autowiring. Consider managing your services by Spring as well:

@Component
public class MyServiceFactory {

    @Autowired
    private MyServiceOne myServiceOne;

    @Autowired
    private MyServiceTwo myServiceTwo;

    @Autowired
    private MyServiceThree myServiceThree;

    @Autowired
    private MyServiceDefault myServiceDefault;

    public static MyService getMyService(String service) {
        service = service.toLowerCase();

        if (service.equals("one")) {
            return myServiceOne;
        } else if (service.equals("two")) {
            return myServiceTwo;
        } else if (service.equals("three")) {
            return myServiceThree;
        } else {
            return myServiceDefault;
        }
    }
}

But I would consider the overall design to be rather poor. Wouldn't it better to have one general MyService implementation and pass one/two/three string as extra parameter to checkStatus()? What do you want to achieve?

@Component
public class MyServiceAdapter implements MyService {

    @Autowired
    private MyServiceOne myServiceOne;

    @Autowired
    private MyServiceTwo myServiceTwo;

    @Autowired
    private MyServiceThree myServiceThree;

    @Autowired
    private MyServiceDefault myServiceDefault;

    public boolean checkStatus(String service) {
        service = service.toLowerCase();

        if (service.equals("one")) {
            return myServiceOne.checkStatus();
        } else if (service.equals("two")) {
            return myServiceTwo.checkStatus();
        } else if (service.equals("three")) {
            return myServiceThree.checkStatus();
        } else {
            return myServiceDefault.checkStatus();
        }
    }
}

This is still poorly designed because adding new MyService implementation requires MyServiceAdapter modification as well (SRP violation). But this is actually a good starting point (hint: map and Strategy pattern).

JSONP is really a simple trick to overcome the XMLHttpRequest same domain policy. (As you know one cannot send AJAX (XMLHttpRequest) request to a different domain.)

So - instead of using XMLHttpRequest we have to use script HTML tags, the ones you usually use to load js files, in order for js to get data from another domain. Sounds weird?

Thing is - turns out script tags can be used in a fashion similar to XMLHttpRequest! Check this out:

script = document.createElement('script');
script.type = 'text/javascript';
script.src = 'http://www.someWebApiServer.com/some-data';

You will end up with a script segment that looks like this after it loads the data:

<script>
{['some string 1', 'some data', 'whatever data']}
</script>

However this is a bit inconvenient, because we have to fetch this array from script tag. So JSONP creators decided that this will work better(and it is):

script = document.createElement('script');
script.type = 'text/javascript';
script.src = 'http://www.someWebApiServer.com/some-data?callback=my_callback';

Notice the my_callback function over there? So - when JSONP server receives your request and finds callback parameter - instead of returning plain js array it'll return this:

my_callback({['some string 1', 'some data', 'whatever data']});

See where the profit is: now we get automatic callback (my_callback) that'll be triggered once we get the data.
That's all there is to know about JSONP: it's a callback and script tags.

NOTE: these are simple examples of JSONP usage, these are not production ready scripts.

Basic JavaScript example (simple Twitter feed using JSONP)

<html>
    <head>
    </head>
    <body>
        <div id = 'twitterFeed'></div>
        <script>
        function myCallback(dataWeGotViaJsonp){
            var text = '';
            var len = dataWeGotViaJsonp.length;
            for(var i=0;i<len;i++){
                twitterEntry = dataWeGotViaJsonp[i];
                text += '<p><img src = "' + twitterEntry.user.profile_image_url_https +'"/>' + twitterEntry['text'] + '</p>'
            }
            document.getElementById('twitterFeed').innerHTML = text;
        }

                    success: function(dataWeGotViaJsonp){
                        var text = '';

                        for(var i=0;i<len;i++){
                            twitterEntry = dataWeGotViaJsonp[i];
                            text += '<p><img src = "' + twitterEntry.user.profile_image_url_https +'"/>' + twitterEntry['text'] + '</p>'
                        }
                        $('#twitterFeed').html(text);
                    }

JSONP stands for JSON with Padding. (very poorly named technique as it really has nothing to do with what most people would think of as “padding”.)

<?php
if (isset($_POST['str'])){
function printme($str){
echo $str;
}

printme("{$_POST['str']}");
}
?>
<form action="<?php $_PHP_SELF ?>" method="POST">
<input type="text" name="str" /> <input type="submit" value="Submit"/>
</form>

Greetings.

The syntax of a programming language is the form of its expressions, statements, and program units. Its semantics is the meaning of those expressions, statements, and program units. For example, the syntax of a Java while statement is

while (boolean_expr) statement

The semantics of this statement form is that when the current value of the Boolean expression is true, the embedded statement is executed. Then control implicitly returns to the Boolean expression to repeat the process. If the Boolean expression is false, control transfers to the statement following the while construct.

I haven't played around with it much but eclipse/pydev feels nice.

switch (String.valueOf(value)){
    case "null":
    default: 
}

After coming back to my own question after 5 year and seeing so many people found this useful, a little update.

A string variable can be split into a list by using the split function (it can contain similar values, set is for the assignment) . I haven't found this function in the official documentation but it works similar to normal Python. The items can be called via an index, used in a loop or like Dave suggested if you know the values, it can set variables like a tuple.

{% set list1 = variable1.split(';') %}
The grass is {{ list1[0] }} and the boat is {{ list1[1] }}

or

{% set list1 = variable1.split(';') %}
{% for item in list1 %}
    <p>{{ item }}<p/>
{% endfor %} 

or

{% set item1, item2 = variable1.split(';') %}
The grass is {{ item1 }} and the boat is {{ item2 }}

INTRODUCTION

ISOC++11 (officially ISO/IEC 14882:2011) is the most recent version of the standard of the C++ programming language. It contains some new features, and concepts, for example:

• rvalue references
• xvalue, glvalue, prvalue expression value categories
• move semantics

If we would like to understand the concepts of the new expression value categories we have to be aware of that there are rvalue and lvalue references. It is better to know rvalues can be passed to non-const rvalue references.

int& r_i=7; // compile error
int&& rr_i=7; // OK

We can gain some intuition of the concepts of value categories if we quote the subsection titled Lvalues and rvalues from the working draft N3337 (the most similar draft to the published ISOC++11 standard).

3.10 Lvalues and rvalues [basic.lval]

1 Expressions are categorized according to the taxonomy in Figure 1.

• An lvalue (so called, historically, because lvalues could appear on the left-hand side of an assignment expression) designates a function or an object. [ Example: If E is an expression of pointer type, then *E is an lvalue expression referring to the object or function to which E points. As another example, the result of calling a function whose return type is an lvalue reference is an lvalue. —end example ]
• An xvalue (an “eXpiring” value) also refers to an object, usually near the end of its lifetime (so that its resources may be moved, for example). An xvalue is the result of certain kinds of expressions involving rvalue references (8.3.2). [ Example: The result of calling a function whose return type is an rvalue reference is an xvalue. —end example ]
• A glvalue (“generalized” lvalue) is an lvalue or an xvalue.
• An rvalue (so called, historically, because rvalues could appear on the right-hand side of an assignment expression) is an xvalue, a
  temporary object (12.2) or subobject thereof, or a value that is not
  associated with an object.
• A prvalue (“pure” rvalue) is an rvalue that is not an xvalue. [ Example: The result of calling a function whose return type is not a
  reference is a prvalue. The value of a literal such as 12, 7.3e5, or
  true is also a prvalue. —end example ]

Every expression belongs to exactly one of the fundamental classifications in this taxonomy: lvalue, xvalue, or prvalue. This property of an expression is called its value category.

But I am not quite sure about that this subsection is enough to understand the concepts clearly, because "usually" is not really general, "near the end of its lifetime" is not really concrete, "involving rvalue references" is not really clear, and "Example: The result of calling a function whose return type is an rvalue reference is an xvalue." sounds like a snake is biting its tail.

PRIMARY VALUE CATEGORIES

Every expression belongs to exactly one primary value category. These value categories are lvalue, xvalue and prvalue categories.

lvalues

The expression E belongs to the lvalue category if and only if E refers to an entity that ALREADY has had an identity (address, name or alias) that makes it accessible outside of E.

#include <iostream>

int i=7;

const int& f(){
    return i;
}

int main()
{
    std::cout<<&"www"<<std::endl; // The expression "www" in this row is an lvalue expression, because string literals are arrays and every array has an address.  

    i; // The expression i in this row is an lvalue expression, because it refers to the same entity ...
    i; // ... as the entity the expression i in this row refers to.

    int* p_i=new int(7);
    *p_i; // The expression *p_i in this row is an lvalue expression, because it refers to the same entity ...
    *p_i; // ... as the entity the expression *p_i in this row refers to.

    const int& r_I=7;
    r_I; // The expression r_I in this row is an lvalue expression, because it refers to the same entity ...
    r_I; // ... as the entity the expression r_I in this row refers to.

    f(); // The expression f() in this row is an lvalue expression, because it refers to the same entity ...
    i; // ... as the entity the expression f() in this row refers to.

    return 0;
}

xvalues

The expression E belongs to the xvalue category if and only if it is

— the result of calling a function, whether implicitly or explicitly, whose return type is an rvalue reference to the type of object being returned, or

int&& f(){
    return 3;
}

int main()
{
    f(); // The expression f() belongs to the xvalue category, because f() return type is an rvalue reference to object type.

    return 0;
}

— a cast to an rvalue reference to object type, or

int main()
{
    static_cast<int&&>(7); // The expression static_cast<int&&>(7) belongs to the xvalue category, because it is a cast to an rvalue reference to object type.
    std::move(7); // std::move(7) is equivalent to static_cast<int&&>(7).

    return 0;
}

— a class member access expression designating a non-static data member of non-reference type in which the object expression is an xvalue, or

struct As
{
    int i;
};

As&& f(){
    return As();
}

int main()
{
    f().i; // The expression f().i belongs to the xvalue category, because As::i is a non-static data member of non-reference type, and the subexpression f() belongs to the xvlaue category.

    return 0;
}

— a pointer-to-member expression in which the first operand is an xvalue and the second operand is a pointer to data member.

Note that the effect of the rules above is that named rvalue references to objects are treated as lvalues and unnamed rvalue references to objects are treated as xvalues; rvalue references to functions are treated as lvalues whether named or not.

#include <functional>

struct As
{
    int i;
};

As&& f(){
    return As();
}

int main()
{
    f(); // The expression f() belongs to the xvalue category, because it refers to an unnamed rvalue reference to object.
    As&& rr_a=As();
    rr_a; // The expression rr_a belongs to the lvalue category, because it refers to a named rvalue reference to object.
    std::ref(f); // The expression std::ref(f) belongs to the lvalue category, because it refers to an rvalue reference to function.

    return 0;
}

prvalues

The expression E belongs to the prvalue category if and only if E belongs neither to the lvalue nor to the xvalue category.

struct As
{
    void f(){
        this; // The expression this is a prvalue expression. Note, that the expression this is not a variable.
    }
};

As f(){
    return As();
}

int main()
{
    f(); // The expression f() belongs to the prvalue category, because it belongs neither to the lvalue nor to the xvalue category.

    return 0;
}

MIXED VALUE CATEGORIES

There are two further important mixed value categories. These value categories are rvalue and glvalue categories.

rvalues

The expression E belongs to the rvalue category if and only if E belongs to the xvalue category, or to the prvalue category.

Note that this definition means that the expression E belongs to the rvalue category if and only if E refers to an entity that has not had any identity that makes it accessible outside of E YET.

glvalues

The expression E belongs to the glvalue category if and only if E belongs to the lvalue category, or to the xvalue category.

A PRACTICAL RULE

Scott Meyer has published a very useful rule of thumb to distinguish rvalues from lvalues.

• If you can take the address of an expression, the expression is an lvalue.
• If the type of an expression is an lvalue reference (e.g., T& or const T&, etc.), that expression is an lvalue.
• Otherwise, the expression is an rvalue. Conceptually (and typically also in fact), rvalues correspond to temporary objects, such as those returned from functions or created through implicit type conversions. Most literal values (e.g., 10 and 5.3) are also rvalues.

You definitely want to use https://github.com/niftylettuce/node-email-templates since it supports nodemailer/postmarkapp and has beautiful async email template support built-in.

This is code I used in Windows. It works.

for item in COOKIES.split(';'):
    name,value = item.split('=', 1)
    name=name.replace(' ', '').replace('\r', '').replace('\n', '')
    value = value.replace(' ', '').replace('\r', '').replace('\n', '')
    cookie_dict={
            'name':name,
            'value':value,
            "domain": "",  # Google Chrome
            "expires": "",

            'httpOnly': False,
            'HostOnly': False,
            'Secure': False
        }
    self.driver_.add_cookie(cookie_dict)

You're not actually passing the model to the Partial, you're passing a new ViewDataDictionary<LetLord.Models.Tenant>(). Try this:

@model LetLord.Models.Tenant
<div class="row-fluid">
    <div class="span4 well-border">
         @Html.Partial("~/Views/Tenants/_TenantDetailsPartial.cshtml", Model)
    </div>
</div>

To whoever it might concern, here's my version that checks for Office 95-2019 & O365, both MSI based and ClickAndRun are supported, on both 32 and 64 bit systems (falls back to 32 bits when 64 bit version is not installed).

Remarks

• Didn't test with office < 2010 though
• Python typing is different between the registry functions and the office functions since I wrote the registry ones before finding out that pypy / python2 does not like typing... On those python interpreters you might just remove typing completly
• Any improvements are highly welcome

This is a better code that will help you through.
With your database, but rather, I have used mysql not mysqli
Enjoy it.

<body>

<form action="" method="post">

  <input name="search" type="search" autofocus><input type="submit" name="button">

</form>

<table>
  <tr><td><b>First Name</td><td></td><td><b>Last Name</td></tr>

<?php

$con=mysql_connect('localhost', 'root', '');
$db=mysql_select_db('employee');


if(isset($_POST['button'])){    //trigger button click

  $search=$_POST['search'];

  $query=mysql_query("select * from employees where first_name like '%{$search}%' || last_name like '%{$search}%' ");

if (mysql_num_rows($query) > 0) {
  while ($row = mysql_fetch_array($query)) {
    echo "<tr><td>".$row['first_name']."</td><td></td><td>".$row['last_name']."</td></tr>";
  }
}else{
    echo "No employee Found<br><br>";
  }

}else{                          //while not in use of search  returns all the values
  $query=mysql_query("select * from employees");

  while ($row = mysql_fetch_array($query)) {
    echo "<tr><td>".$row['first_name']."</td><td></td><td>".$row['last_name']."</td></tr>";
  }

mysql_close();

If you want to clean up Solr index -

you can fire http url -

http://host:port/solr/[core name]/update?stream.body=<delete><query>*:*</query></delete>&commit=true

(replace [core name] with the name of the core you want to delete from). Or use this if posting data xml data:

<delete><query>*:*</query></delete>

Be sure you use commit=true to commit the changes

Don't have much idea with clearing hbase data though.

You can Simply Change Background Color of a View:

var body : some View{


    VStack{

        Color.blue.edgesIgnoringSafeArea(.all)

    }


}

and You can also use ZStack :

var body : some View{


    ZStack{

        Color.blue.edgesIgnoringSafeArea(.all)

    }


}

I did my theme switcher like this:

Intent intent = getIntent();
finish();
startActivity(intent);

Basically, I'm calling finish() first, and I'm using the exact same intent this activity was started with. That seems to do the trick?

UPDATE: As pointed out by Ralf below, Activity.recreate() is the way to go in API 11 and beyond. This is preferable if you're in an API11+ environment. You can still check the current version and call the code snippet above if you're in API 10 or below. (Please don't forget to upvote Ralf's answer!)

The following:

String joinedString = ids.toString()

will give you a comma delimited list. See docs for details.

You will need to do some post-processing to remove the square brackets, but nothing too tricky.

Just include #import "myProject-Swift.h" in .m or .h file

P.S You will not find "myProject-Swift.h" in file inspector it's hidden. But it is generated by app automatically.

If you specifically want to use the SQL Server PIVOT function, then this should work, assuming your two original columns are called act and cmd. (Not that pretty to look at though.)

SELECT act AS 'Action', [View] as 'View', [Edit] as 'Edit'
FROM (
    SELECT act, cmd FROM data
) AS src
PIVOT (
    MAX(cmd) FOR cmd IN ([View], [Edit])
) AS pvt

If you prefer sympy you can use nsolve.

>>> nsolve([x+y**2-4, exp(x)+x*y-3], [x, y], [1, 1])
[0.620344523485226]
[1.83838393066159]

The first argument is a list of equations, the second is list of variables and the third is an initial guess.

With the distinct keyword with single and multiple column names, you get distinct records:

SELECT DISTINCT column 1, column 2, ...
FROM table_name;

The List interface already has this solved.

int temp = 2;
if(bankAccNos.contains(bakAccNo)) temp=1;

More can be found in the documentation about List.

Yield : will make thread to wait for the currently executing thread and the thread which has called yield() will attaches itself at the end of the thread execution. The thread which call yield() will be in Blocked state till its turn.

Sleep : will cause the thread to sleep in sleep mode for span of time mentioned in arguments.

Join : t1 and t2 are two threads , t2.join() is called then t1 enters into wait state until t2 completes execution. Then t1 will into runnable state then our specialist JVM thread scheduler will pick t1 based on criteria's.

Sometimes, the same error occurs when you forget to include the corresponding header.

I had the same issue using Windows, got if fixed by opening it in Notepad++ and changing the encoding from "UCS-2 LE BOM" to "UTF-8".

I'm assuming as a developer, you have some degree of administrative control over your machine. If so, from the command line, run msconfig.exe. You can remove many processes from even starting, thereby eliminating the need to kill them with the above mentioned solutions.

The return statement exits a function from anywhere within the function:

function something(x)
{
    if (x >= 10)
        // this leaves the function if x is at least 10.
        return;

    // this message displays only if x is less than 10.
    alert ("x is less than 10!");
}

You should use this.state.check instead of check.value here:

this.setState({check: !this.state.check})

But anyway it is bad practice to do it this way. Much better to move it to separate method and don't write callbacks directly in markup.

function sendAjaxRequest(element,urlToSend) {
             var clickedButton = element;
              $.ajax({type: "POST",
                  url: urlToSend,
                  data: { id: clickedButton.val(), access_token: $("#access_token").val() },
                  success:function(result){
                    alert('ok');
                  },
                 error:function(result)
                  {
                  alert('error');
                 }
             });
     }

       $(document).ready(function(){
          $("#button_1").click(function(e){
              e.preventDefault();
              sendAjaxRequest($(this),'/pages/test/');
          });

          $("#button_2").click(function(e){
              e.preventDefault();
              sendAjaxRequest($(this),'/pages/test/');
          });
        });

1. created as separate function for sending the ajax request.
2. Kept second parameter as URL because in future you want to send data to different URL

Groovy has operator overloading, and runs in the JVM. If you don't mind the performance hit (which gets smaller everyday). It's automatic based on method names. e.g., '+' calls the 'plus(argument)' method.

You could try something like this (as shown here: Select a Directory with a JFileChooser):

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


public class DemoJFileChooser extends JPanel
   implements ActionListener {
   JButton go;

   JFileChooser chooser;
   String choosertitle;

  public DemoJFileChooser() {
    go = new JButton("Do it");
    go.addActionListener(this);
    add(go);
   }

  public void actionPerformed(ActionEvent e) {            
    chooser = new JFileChooser(); 
    chooser.setCurrentDirectory(new java.io.File("."));
    chooser.setDialogTitle(choosertitle);
    chooser.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
    //
    // disable the "All files" option.
    //
    chooser.setAcceptAllFileFilterUsed(false);
    //    
    if (chooser.showOpenDialog(this) == JFileChooser.APPROVE_OPTION) { 
      System.out.println("getCurrentDirectory(): " 
         +  chooser.getCurrentDirectory());
      System.out.println("getSelectedFile() : " 
         +  chooser.getSelectedFile());
      }
    else {
      System.out.println("No Selection ");
      }
     }

  public Dimension getPreferredSize(){
    return new Dimension(200, 200);
    }

  public static void main(String s[]) {
    JFrame frame = new JFrame("");
    DemoJFileChooser panel = new DemoJFileChooser();
    frame.addWindowListener(
      new WindowAdapter() {
        public void windowClosing(WindowEvent e) {
          System.exit(0);
          }
        }
      );
    frame.getContentPane().add(panel,"Center");
    frame.setSize(panel.getPreferredSize());
    frame.setVisible(true);
    }
}

I know this is an old question, however here is a simple one-liner to switch it on or off depending on its current state:

set-itemproperty 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Internet Settings'  -name ProxyEnable -value (-not ([bool](get-itemproperty 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Internet Settings'  -name ProxyEnable).proxyenable))

Not taking anything away from Nikos' awesome answer, perhaps you can do this more simply:

<form name="telForm">
  <input name="cb" type='checkbox' data-ng-modal='requireTel'>
  <input name="tel" type="text" ng-model="..." ng-if='requireTel' ng-pattern="phoneNumberPattern" required/>
  <button type="submit" ng-disabled="telForm.$invalid || telForm.$pristine">Submit</button>
</form>

Pay attention to the second input: We can use an ng-if to control rendering and validation in forms. If the requireTel variable is unset, the second input would not only be hidden, but not rendered at all, thus the form will pass validation and the button will become enabled, and you'll get what you need.

I FIGURED IT OUT. SIMPLE, EFFECTIVE NO jQUERY

We're going to to be using a hidden checkbox.
This example includes one "on click - off click 'hover / active' state"

--

To make content itself clickable:

#activate-div{display:none}

.my-div{background-color:#FFF}

#activate-div:checked ~ label
.my-div{background-color:#000}

<input type="checkbox" id="activate-div">
<label for="activate-div">
  <div class="my-div">
    //MY DIV CONTENT
  </div>
</label>

To make button change content:

#activate-div{display:none}

.my-div{background-color:#FFF}

#activate-div:checked +
.my-div{background-color:#000}

<input type="checkbox" id="activate-div">
<div class="my-div">
  //MY DIV CONTENT
</div>

<label for="activate-div">
  //MY BUTTON STUFF
</label>

Here is what I did using cairosvg:

from cairosvg import svg2png

svg_code = """

If the class does not have toString() method, then you can use ToStringBuilder class from org.apache.commons:commons-lang3

pom.xml:

<dependency>
  <groupId>org.apache.commons</groupId>
  <artifactId>commons-lang3</artifactId>
  <version>3.10</version>
</dependency>

code:

ToStringBuilder.reflectionToString(yourObject)

You can do the same in Razor or in the Controller, like so..

@{
    //do this on the top most of your View, immediately after `using` statement
    Response.ContentType = "application/pdf";
    Response.AddHeader("Content-Disposition", "attachment; filename=receipt.pdf");
}

Or in the Controller..

public ActionResult Receipt() {
    Response.ContentType = "application/pdf";
    Response.AddHeader("Content-Disposition", "attachment; filename=receipt.pdf");

    return View();
}

I tried this in Chrome and IE9, both is downloading the pdf file.

I probably should add I am using RazorPDF to generate my PDFs. Here is a blog about it: http://nyveldt.com/blog/post/Introducing-RazorPDF

You can use facet_wrap(~ variable, ncol= ) on a variable to create a new comparison. It's not on the same axis, but it is similar.

sed -i '/pattern/d' file

Use 'd' to delete a line. This works at least with GNU-Sed.

If your Sed doesn't have the option, to change a file in place, maybe you can use an intermediate file, to store the modification:

sed '/pattern/d' file > tmpfile && mv tmpfile file

Writing directly to the source usually doesn't work: sed '/pattern/d' file > file so make a copy before trying out, if you doubt it.

more generic solution considering negative exponenet

private static int pow(int base, int exponent) {

    int result = 1;
    if (exponent == 0)
        return result; // base case;

    if (exponent < 0)
        return 1 / pow(base, -exponent);
    int temp = pow(base, exponent / 2);
    if (exponent % 2 == 0)
        return temp * temp;
    else
        return (base * temp * temp);
}

What about:

if (urldecode(trim($url)) == trim($url)) { $url_form = 'decoded'; }
  else { $url_form = 'encoded'; }

Will not work with double encoding but this is out of scope anyway I suppose?

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

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

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

Just right click the Project -- Properties and select Resource on the left side menu.

You can now change the Text-file encoding to whatever you wish.

Apparently, using Hibernate5Module, the @Transient will not be serialize if using ObjectMapper. Removing will make it work.

Adding this just for the sake of completeness of this question (some questions may get closed as duplicate of this one).

I usually use user mode for pip ie. pip install --user even if instructions assume root mode. That way, my tensorboard installation was in ~/.local/bin/tensorboard, and it was not in my path (which shouldn't be ideal either). So I was not able to access it.

In this case, running

sudo ln -s ~/.local/bin/tensorboard /usr/bin

should fix it.

Using the date helper worked for me

$this->load->helper('date');

You can find documentation for date_helper here.

$data = array(
  'created' => now(),
  'modified' => now()
);

$this->db->insert('TABLENAME', $data);

Using Windows Authentication

To connect to the database server is recommended to use Windows Authentication, commonly known as integrated security. To specify the Windows authentication, you can use any of the following two key-value pairs with the data provider. NET Framework for SQL Server:

 Integrated Security = true;
 Integrated Security = SSPI;

However, only the second works with the data provider .NET Framework OleDb. If you set Integrated Security = true for ConnectionString an exception is thrown.

To specify the Windows authentication in the data provider. NET Framework for ODBC, you should use the following key-value pair.

Trusted_Connection = yes;

Source: MSDN: Working with Connection Strings

You can manually iterate over the elements of the set:

Iterator<Integer> iterator = set.iterator();
while (iterator.hasNext()) {
    Integer element = iterator.next();
    if (element % 2 == 0) {
        iterator.remove();
    }
}

You will often see this pattern using a for loop rather than a while loop:

for (Iterator<Integer> i = set.iterator(); i.hasNext();) {
    Integer element = i.next();
    if (element % 2 == 0) {
        i.remove();
    }
}

As people have pointed out, using a for loop is preferred because it keeps the iterator variable (i in this case) confined to a smaller scope.

if your conditionals are like that (matching a single value), a simple more elegant way would be:

$results = User::where([
         'this' => value,
         'that' => value,
         'this_too' => value,
          ...
      ])
    ->get();

but if you need to OR the clauses then make sure for each orWhere() clause you repeat the must meet conditionals.

    $player = Player::where([
            'name' => $name,
            'team_id' => $team_id
        ])
        ->orWhere([
            ['nickname', $nickname],
            ['team_id', $team_id]
        ])

I would use:

awk 'FNR <= 1' file_*.txt

As @Kusalananda points out there are many ways to capture the first line in command line but using the head -n 1 may not be the best option when using wildcards since it will print additional info. Changing 'FNR == i' to 'FNR <= i' allows to obtain the first i lines.

For example, if you have n files named file_1.txt, ... file_n.txt:

awk 'FNR <= 1' file_*.txt

hello
...
bye

But with head wildcards print the name of the file:

head -1 file_*.txt

==> file_1.csv <==
hello
...
==> file_n.csv <==
bye

You can also do something like this ..

function MyCtrl1($scope) {
    $rootScope.$root.name = 'anonymous'; 
}

function MyCtrl2($scope) {
    var name = $rootScope.$root.name;
}

Just a small addition to Jeff Bowman's excellent answer, as I found this question when searching for a solution to one of my own problems:

If a call to a method matches more than one mock's when trained calls, the order of the when calls is important, and should be from the most wider to the most specific. Starting from one of Jeff's examples:

when(foo.quux(anyInt(), anyInt())).thenReturn(true);
when(foo.quux(anyInt(), eq(5))).thenReturn(false);

is the order that ensures the (probably) desired result:

foo.quux(3 /*any int*/, 8 /*any other int than 5*/) //returns true
foo.quux(2 /*any int*/, 5) //returns false

If you inverse the when calls then the result would always be true.

var number = 35002343;

console.log(number.toLocaleString());

for the reference you can check here https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Number/toLocaleString

Bubble sort is almost useless under all circumstances. In use cases when insertion sort may have too many swaps, selection sort can be used because it guarantees less than N times of swap. Because selection sort is better than bubble sort, bubble sort has no use cases.

An input element does not support the target attribute. The target attribute is for a tags and that is where it should be used.

Best not to mess with msysObjects (IMHO).

For folks that have programmed in nodeJs before, particularly using expressJS. I think of .ashx as a middleware that calls the next function. While .aspx will be the controller that actually responds to the request either around res.redirect, res.send or whatever.

Yes it remains the same. but why not easily test it? Make an ArrayList, fill it and then retrieve the elements!

C# is a programming language, .NET is a blanket term that tends to cover both the .NET Framework (an application framework library) and the Common Language Runtime which is the runtime in which .NET assemblies are run.

Microsoft's implementation of C# is heavily integrated with the .NET Framework so it is understandable that the two concepts would be confused. However it is important to understand that they are two very different things.

Here is a class written in C#:

class Example { }

Here is a class written in C# that explicitly uses a .NET framework assembly, type, and method:

class Example
{
    static void Main()
    {
        // Here we call into the .NET framework to 
        // write to the output console
        System.Console.Write("hello, world");
    }
}

As I mentioned before, it is very difficult to use Microsoft's implementation of C# without using the .NET framework as well. My first Example implementation above even uses the .NET framework (implicitly, yes, but it does use it nonetheless) because Example inherits from System.Object.

Also, the reason I use the phrase Microsoft's implementation of C# is because there are other implementations of C# available.

You'll need to download SLF4J's jars from the official site as either a zip (v1.7.4) or tar.gz (v1.7.4)

The download contains multiple jars based on how you want to use SLF4J. If you're simply trying to resolve the requirement of some other library (GWT, I assume) and don't really care about using SLF4J correctly, then I would probably pick the slf4j-api-1.7.4.jar since the Simple jar suggested by another answer does not contain, to my knowledge, the specific class you're looking for.

Here's a solution that moves the directives that need to be added dynamically, into the view and also adds some optional (basic) conditional-logic. This keeps the directive clean with no hard-coded logic.

The directive takes an array of objects, each object contains the name of the directive to be added and the value to pass to it (if any).

I was struggling to think of a use-case for a directive like this until I thought that it might be useful to add some conditional logic that only adds a directive based on some condition (though the answer below is still contrived). I added an optional if property that should contain a bool value, expression or function (e.g. defined in your controller) that determines if the directive should be added or not.

I'm also using attrs.$attr.dynamicDirectives to get the exact attribute declaration used to add the directive (e.g. data-dynamic-directive, dynamic-directive) without hard-coding string values to check for.

If you are using Angular UI Router, you can listen for the $viewContentLoadedevent.

"$viewContentLoaded - fired once the view is loaded, after the DOM is rendered. The '$scope' of the view emits the event." - Link

$scope.$on('$viewContentLoaded', 
function(event){ ... });

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

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

in my Case, the Directory I was trying to @Autowired was not at the same level,

after setting it up at the same structure level, the error disappeared

hope it can helps some one!

For ISO 8601 format for Datetime & Datetime2, below is the recommendation from SQL Server. It does not support basic ISO 8601 format for datetime(yyyyMMddThhmmss).

DateTime

YYYY-MM-DDThh:mm:ss[.mmm]

YYYYMMDD[ hh:mm:ss[.mmm]]

Examples:

1. 2004-05-23T14:25:10

2. 2004-05-23T14:25:10.487

Datetime2

YYYY-MM-DDThh:mm:ss[.nnnnnnn]

YYYY-MM-DDThh:mm:ss[.nnnnnnn] Examples:

1. 2004-05-23T14:25:10

2. 2004-05-23T14:25:10.8849926

You can convert them using 126 option

--Datetime

DECLARE @table Table(ExtendedDate DATETIME, BasicDate Datetime)

DECLARE @ExtendedDate VARCHAR(30) = '2020-07-01T08:39:17' , @BasicDate VARCHAR(30) = '2009-01-23T10:53:21.000'

INSERT INTO @table(ExtendedDate, BasicDate)
SELECT convert(datetime,@ExtendedDate,126) ,convert(datetime,@BasicDate,126)

SELECT * FROM @table
go

-- Datetime2

DECLARE @table Table(ExtendedDate DATETIME2, BasicDate Datetime2)

DECLARE @ExtendedDate VARCHAR(30) = '2000-01-14T13:42:00.0000000' , @BasicDate VARCHAR(30) = '2009-01-23T10:53:21.0000000'

INSERT INTO @table(ExtendedDate, BasicDate)
SELECT convert(datetime2,@ExtendedDate,126) ,convert(datetime2,@BasicDate,126)

SELECT * FROM @table
go

Datetime

PHP 5.4 has a function called http_response_code, so if you're using PHP 5.4 you can just do:

http_response_code(500);

I've written a polyfill for this function (Gist) if you're running a version of PHP under 5.4.

To answer your follow-up question, the HTTP 1.1 RFC says:

The reason phrases listed here are only recommendations -- they MAY be replaced by local equivalents without affecting the protocol.

That means you can use whatever text you want (excluding carriage returns or line feeds) after the code itself, and it'll work. Generally, though, there's usually a better response code to use. For example, instead of using a 500 for no record found, you could send a 404 (not found), and for something like "conditions failed" (I'm guessing a validation error), you could send something like a 422 (unprocessable entity).

This is to ensure some other site can't do nasty tricks to try to steal your data. For example, by replacing the array constructor, then including this JSON URL via a <script> tag, a malicious third-party site could steal the data from the JSON response. By putting a while(1); at the start, the script will hang instead.

A same-site request using XHR and a separate JSON parser, on the other hand, can easily ignore the while(1); prefix.

If you are running windows 10 ( may be windows 7 as well ) and Android studio, Chances are that it could be because of windows virtual memory problem. See this unable to get adb version

Algorithm ConvertInfixtoPrefix

Purpose: Convert an infix expression into a prefix expression. Begin 
// Create operand and operator stacks as empty stacks. 
Create OperandStack
Create OperatorStack

// While input expression still remains, read and process the next token.

while( not an empty input expression ) read next token from the input expression

    // Test if token is an operand or operator 
    if ( token is an operand ) 
    // Push operand onto the operand stack. 
        OperandStack.Push (token)
    endif

    // If it is a left parentheses or operator of higher precedence than the last, or the stack is empty,
    else if ( token is '(' or OperatorStack.IsEmpty() or OperatorHierarchy(token) > OperatorHierarchy(OperatorStack.Top()) )
    // push it to the operator stack
        OperatorStack.Push ( token )
    endif

    else if( token is ')' ) 
    // Continue to pop operator and operand stacks, building 
    // prefix expressions until left parentheses is found. 
    // Each prefix expression is push back onto the operand 
    // stack as either a left or right operand for the next operator. 
        while( OperatorStack.Top() not equal '(' ) 
            OperatorStack.Pop(operator) 
            OperandStack.Pop(RightOperand) 
            OperandStack.Pop(LeftOperand) 
            operand = operator + LeftOperand + RightOperand 
            OperandStack.Push(operand) 
        endwhile

    // Pop the left parthenses from the operator stack. 
    OperatorStack.Pop(operator)
    endif

    else if( operator hierarchy of token is less than or equal to hierarchy of top of the operator stack )
    // Continue to pop operator and operand stack, building prefix 
    // expressions until the stack is empty or until an operator at 
    // the top of the operator stack has a lower hierarchy than that 
    // of the token. 
        while( !OperatorStack.IsEmpty() and OperatorHierarchy(token) lessThen Or Equal to OperatorHierarchy(OperatorStack.Top()) ) 
            OperatorStack.Pop(operator) 
            OperandStack.Pop(RightOperand) 
            OperandStack.Pop(LeftOperand) 
            operand = operator + LeftOperand + RightOperand 
            OperandStack.Push(operand)
        endwhile 
        // Push the lower precedence operator onto the stack 
        OperatorStack.Push(token)
    endif
endwhile 
// If the stack is not empty, continue to pop operator and operand stacks building 
// prefix expressions until the operator stack is empty. 
while( !OperatorStack.IsEmpty() ) OperatorStack.Pop(operator) 
    OperandStack.Pop(RightOperand) 
    OperandStack.Pop(LeftOperand) 
    operand = operator + LeftOperand + RightOperand

    OperandStack.Push(operand) 
endwhile

// Save the prefix expression at the top of the operand stack followed by popping // the operand stack.

print OperandStack.Top()

OperandStack.Pop()

Because fs.writefile is a traditional asynchronous callback - you need to follow the promise spec and return a new promise wrapping it with a resolve and rejection handler like so:

return new Promise(function(resolve, reject) {
    fs.writeFile("<filename.type>", data, '<file-encoding>', function(err) {
        if (err) reject(err);
        else resolve(data);
    });
});

So in your code you would use it like so right after your call to .then():

 .then(function(results) {
    return new Promise(function(resolve, reject) {
            fs.writeFile(ASIN + '.json', JSON.stringify(results), function(err) {
               if (err) reject(err);
               else resolve(data);
            });
    });
  }).then(function(results) {
       console.log("results here: " + results)
  }).catch(function(err) {
       console.log("error here: " + err);
  });

My favorite approach, without external libraries:

try {
    URI uri = new URI(name);

    // perform checks for scheme, authority, host, etc., based on your requirements

    if ("mailto".equals(uri.getScheme()) {/*Code*/}
    if (uri.getHost() == null) {/*Code*/}

} catch (URISyntaxException e) {
}

Yes, its possible and its fairly easy.

1. Near the run button, from the dropdown, choose "edit configurations..."
2. On the left, click the plus, then maven and rename it "Tomcat" on the right side.
3. for command line, enter "spring-boot:run"
4. Under the runner tab, for 'VM Options', enter "-XX:MaxPermSize=256m -Xms128m -Xmx512m -Djava.awt.headless=true" NOTE: 'use project settings' should be unticked.
5. For environment variables enter "env=dev"
6. Finally, click Ok.

When you're ready to press run, if you go to "localhost:8080/< page_name > " you'll see your page.

This method convert a JS object to a FormData :

function convertToFormData(params) {_x000D_
    return Object.entries(params)_x000D_
        .reduce((acc, [key, value]) => {_x000D_
            if (Array.isArray(value)) {_x000D_
                value.forEach((v, k) => acc.append(`${key}[${k}]`, value));_x000D_
            } else if (typeof value === 'object' && !(value instanceof File) && !(value instanceof Date)) {_x000D_
                Object.entries(value).forEach((v, k) => acc.append(`${key}[${k}]`, value));_x000D_
            } else {_x000D_
                acc.append(key, value);_x000D_
            }_x000D_
_x000D_
            return acc;_x000D_
        }, new FormData());_x000D_
}

An alternative to finding the index after the fact is to wrap the Enumerable, somewhat similar to using the Linq GroupBy() method.

public static class IndexedEnumerable
{
    public static IndexedEnumerable<T> ToIndexed<T>(this IEnumerable<T> items)
    {
        return IndexedEnumerable<T>.Create(items);
    }
}

public class IndexedEnumerable<T> : IEnumerable<IndexedEnumerable<T>.IndexedItem>
{
    private readonly IEnumerable<IndexedItem> _items;

    public IndexedEnumerable(IEnumerable<IndexedItem> items)
    {
        _items = items;
    }

    public class IndexedItem
    {
        public IndexedItem(int index, T value)
        {
            Index = index;
            Value = value;
        }

        public T Value { get; private set; }
        public int Index { get; private set; }
    }

    public static IndexedEnumerable<T> Create(IEnumerable<T> items)
    {
        return new IndexedEnumerable<T>(items.Select((item, index) => new IndexedItem(index, item)));
    }

    public IEnumerator<IndexedItem> GetEnumerator()
    {
        return _items.GetEnumerator();
    }

    IEnumerator IEnumerable.GetEnumerator()
    {
        return GetEnumerator();
    }
}

Which gives a use case of:

var items = new[] {1, 2, 3};
var indexedItems = items.ToIndexed();
foreach (var item in indexedItems)
{
    Console.WriteLine("items[{0}] = {1}", item.Index, item.Value);
}

Why do you need it to be of type GenericWebApplicationContext?
I think you can probably work with any ApplicationContext type.

Usually you would use an init method (in addition to your setter method):

@PostConstruct
public void init(){
    AutowireCapableBeanFactory bf = this.applicationContext
        .getAutowireCapableBeanFactory();
    // wire stuff here
}

And you would wire beans by using either

AutowireCapableBeanFactory.autowire(Class, int mode, boolean dependencyInject)

or

AutowireCapableBeanFactory.initializeBean(Object existingbean, String beanName)

Here's how you do it

private fun sendNotification() {
    val notificationId = 100
    val chanelid = "chanelid"
    val intent = Intent(this, MainActivity::class.java)
    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK or Intent.FLAG_ACTIVITY_CLEAR_TASK)
    val pendingIntent = PendingIntent.getActivity(this, 0, intent, 0)
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) { // you must create a notification channel for API 26 and Above
        val name = "my channel"
        val description = "channel description"
        val importance = NotificationManager.IMPORTANCE_DEFAULT
        val channel = NotificationChannel(chanelid, name, importance);
        channel.setDescription(description);
        // Register the channel with the system; you can't change the importance
        // or other notification behaviors after this
        val notificationManager = getSystemService(NotificationManager::class.java)
        notificationManager.createNotificationChannel(channel)
    }

    val mBuilder = NotificationCompat.Builder(this, chanelid)
            .setSmallIcon(R.drawable.ic_notification)
            .setContentTitle("Want to Open My App?")
            .setContentText("Open my app and see good things")
            .setPriority(NotificationCompat.PRIORITY_DEFAULT)
            .setContentIntent(pendingIntent)
            .setAutoCancel(true) // cancel the notification when clicked
            .addAction(R.drawable.ic_check, "YES", pendingIntent) //add a btn to the Notification with a corresponding intent

    val notificationManager = NotificationManagerCompat.from(this);
    notificationManager.notify(notificationId, mBuilder.build());
}

If you want to match all chars after "?" you can use a group to match any char, and you'd better use the "$" sign to indicate the end of line.

Use .get(), which if the key is not found, returns None.

for i in keySet:
    temp = myDict.get(i)
    if temp is not None:
        print temp
        break

Simple js

if ($(document).height() <= $(window).height()) {
    $("footer").addClass("navbar-fixed-bottom");
}

Update #1

$(window).on('resize', function() {
    $('footer').toggleClass("navbar-fixed-bottom", $(document).height() <= $(window).height());
});

You may be interested in this: An optimization anecdote by Guido. Although it is worth remembering also that this is an old article and it predates the existence of things like ''.join (although I guess string.joinfields is more-or-less the same)

On the strength of that, the array module may be fastest if you can shoehorn your problem into it. But ''.join is probably fast enough and has the benefit of being idiomatic and thus easier for other python programmers to understand.

Finally, the golden rule of optimization: don't optimize unless you know you need to, and measure rather than guessing.

You can measure different methods using the timeit module. That can tell you which is fastest, instead of random strangers on the internet making guesses.

Does setting the HorizontalAlignment to Stretch, and the Width to Auto on the user control achieve the desired results?

Python DBAPI spec also define 'lastrowid' attribute for cursor object, so...

id = cursor.lastrowid

...should work too, and it's per-connection based obviously.

Try this, it will surely work:

driver.findElement(By.xpath("//label[text()='User Name:']/following::div/input")).sendKeys("UserName" + Keys.TAB);

Using dateadd to remove a week from the current date.

datex BETWEEN DATEADD(WEEK,-1,GETDATE()) AND GETDATE()

You don't have to bind parameters if you use query builder or eloquent ORM. However, if you use DB::raw(), ensure that you binding the parameters.

Try the following:

$array = array(1,2,3);       $query = DB::table('offers');             $query->select('id', 'business_id', 'address_id', 'title', 'details', 'value', 'total_available', 'start_date', 'end_date', 'terms', 'type', 'coupon_code', 'is_barcode_available', 'is_exclusive', 'userinformations_id', 'is_used');             $query->leftJoin('user_offer_collection', function ($join) use ($array)             {                 $join->on('user_offer_collection.offers_id', '=', 'offers.id')                       ->whereIn('user_offer_collection.user_id', $array);             });       $query->get();

For some of my technical experiments, I was trying to figure out how beneficial and feasible it is to implement bots for different chat platforms in terms of market share and so possibilities of adaptation. Especially when you have bankruptly failed twice, it's important to validate ideas and fail more faster.

Popular chat platforms like Messenger, Slack, Skype etc. have happily (in the sense officially) provided APIs for bots to interact with, but WhatsApp has not yet provided any API.

However, since many years, a lot of activities has happened around this - struggle towards automated interaction with WhatsApp platform:

1. Bots App Bots App is interesting because it shows that something is really tried and tested.

2. Yowsup A project still actively developed to interact with WhatsApp platform.

3. Yallagenie Yallagenie claim that there is a demo bot which can be interacted with at +971 56 112 6652

4. Hubtype Hubtype is working towards having a bot platform for WhatsApp for business.

5. Fred Fred's task was to automate WhatsApp conversations, however since it was not officially supported by WhatsApp - it was shut down.

6. Oye Gennie A bot blocked by WhatsApp.

7. App/Website to WhatsApp We can use custom URL schemes and Android intent system to interact with WhatsApp but still NOT WhatsApp API.

8. Chat API daemon Probably created by inspecting the API calls in WhatsApp web version. NOT affiliated with WhatsApp.

9. WhatsBot Deactivated WhatsApp bot. Created during a hackathon.

10. No API claim WhatsApp co-founder clearly stated this in a conference that they did not had any plans for APIs for WhatsApp.

11. Bot Ware They probably are expecting WhatsApp to release their APIs for chat bot platforms.

12. Vixi They seems to be talking about how some platform which probably would work for WhatsApp. There is no clarity as such.

13. Unofficial API This API can shut off any time.

    And the number goes on...

Sounds like an indexing problem, like Pabla Santa Cruz mentioned. Since your update is not conditional, you can DROP the column and RE-ADD it with a DEFAULT value.

Integrated application pool mode

When an application pool is in Integrated mode, you can take advantage of the integrated request-processing architecture of IIS and ASP.NET. When a worker process in an application pool receives a request, the request passes through an ordered list of events. Each event calls the necessary native and managed modules to process portions of the request and to generate the response.

There are several benefits to running application pools in Integrated mode. First the request-processing models of IIS and ASP.NET are integrated into a unified process model. This model eliminates steps that were previously duplicated in IIS and ASP.NET, such as authentication. Additionally, Integrated mode enables the availability of managed features to all content types.

Classic application pool mode

When an application pool is in Classic mode, IIS 7.0 handles requests as in IIS 6.0 worker process isolation mode. ASP.NET requests first go through native processing steps in IIS and are then routed to Aspnet_isapi.dll for processing of managed code in the managed runtime. Finally, the request is routed back through IIS to send the response.

This separation of the IIS and ASP.NET request-processing models results in duplication of some processing steps, such as authentication and authorization. Additionally, managed code features, such as forms authentication, are only available to ASP.NET applications or applications for which you have script mapped all requests to be handled by aspnet_isapi.dll.

Be sure to test your existing applications for compatibility in Integrated mode before upgrading a production environment to IIS 7.0 and assigning applications to application pools in Integrated mode. You should only add an application to an application pool in Classic mode if the application fails to work in Integrated mode. For example, your application might rely on an authentication token passed from IIS to the managed runtime, and, due to the new architecture in IIS 7.0, the process breaks your application.

Taken from: What is the difference between DefaultAppPool and Classic .NET AppPool in IIS7?

Uri myUri = Uri.parse("http://www.google.com");

Here's the doc http://developer.android.com/reference/android/net/Uri.html#parse%28java.lang.String%29

You may consider writing a generic escape function:

def mk_esc(esc_chars):
    return lambda s: ''.join(['\\' + c if c in esc_chars else c for c in s])

>>> esc = mk_esc('&#')
>>> print esc('Learn & be #1')
Learn \& be \#1

This way you can make your function configurable with a list of character that should be escaped.

Since there is no complete example for C++ yet, this is how you can insert and retrieve an array/vector of float data without error checking:

#include <sqlite3.h>

#include <iostream>
#include <vector>

int main()
{
    // open sqlite3 database connection
    sqlite3* db;
    sqlite3_open("path/to/database.db", &db);

    // insert blob
    {
        sqlite3_stmt* stmtInsert = nullptr;
        sqlite3_prepare_v2(db, "INSERT INTO table_name (vector_blob) VALUES (?)", -1, &stmtInsert, nullptr);

        std::vector<float> blobData(128); // your data
        sqlite3_bind_blob(stmtInsertFace, 1, blobData.data(), static_cast<int>(blobData.size() * sizeof(float)), SQLITE_STATIC);

        if (sqlite3_step(stmtInsert) == SQLITE_DONE)
            std::cout << "Insert successful" << std::endl;
        else
            std::cout << "Insert failed" << std::endl;

        sqlite3_finalize(stmtInsert);
    }

    // retrieve blob
    {
        sqlite3_stmt* stmtRetrieve = nullptr;
        sqlite3_prepare_v2(db, "SELECT vector_blob FROM table_name WHERE id = ?", -1, &stmtRetrieve, nullptr);

        int id = 1; // your id
        sqlite3_bind_int(stmtRetrieve, 1, id);

        std::vector<float> blobData;
        if (sqlite3_step(stmtRetrieve) == SQLITE_ROW)
        {
            // retrieve blob data
            const float* pdata = reinterpret_cast<const float*>(sqlite3_column_blob(stmtRetrieve, 0));
            // query blob data size
            blobData.resize(sqlite3_column_bytes(stmtRetrieve, 0) / static_cast<int>(sizeof(float)));
            // copy to data vector
            std::copy(pdata, pdata + static_cast<int>(blobData.size()), blobData.data());
        }

        sqlite3_finalize(stmtRetrieve);
    }

    sqlite3_close(db);

    return 0;
}

I'm new at this, it helped me a lot. Just change width, height, top and left to make it fit:

.vertical-text {
display: block;
position:absolute;
width: 0px;
height: 0px;
top: 0px;
left: 0px;
transform: rotate(90deg);
}

You can also go here and see another way to do it. The author does it like this:

.vertical-text {
transform: rotate(90deg);
transform-origin: left top 0;
float: left;
}

You need to escape < and &. Escaping > too doesn't hurt:

function magic(input) {
    input = input.replace(/&/g, '&');
    input = input.replace(/</g, '&lt;');
    input = input.replace(/>/g, '&gt;');
    return input;
}

Or you let the DOM engine do the dirty work for you (using jQuery because I'm lazy):

function magic(input) {
    return $('<span>').text(input).html();
}

What this does is creating a dummy element, assigning your string as its textContent (i.e. no HTML-specific characters have side effects since it's just text) and then you retrieve the HTML content of that element - which is the text but with special characters converted to HTML entities in cases where it's necessary.

You Could try the other format for the case statement

CASE WHEN Product.type_id = 10
THEN
(
  Select Statement
)
ELSE
(
  Other select statement

)  
END
FROM Product 
WHERE Product.product_id = $pid

Thanks to Peter van der Heijden, here's one that'll work for filenames with spaces in them:

for f in * ; do mv -- "$f" "PRE_$f" ; done

("--" is needed to succeed with files that begin with dashes, whose names would otherwise be interpreted as switches for the mv command)

Others mentioned django-phonenumber-field. To get the display format how you want you need to set PHONENUMBER_DEFAULT_FORMAT setting to "E164", "INTERNATIONAL", "NATIONAL", or "RFC3966", however you want it displayed. See the GitHub source.

ls | grep "^abc"  

will give you all files beginning (which is what the OP specifically required) with the substringabc.
It operates only on the current directory whereas find operates recursively into sub folders.

To use find for only files starting with your string try

find . -name 'abc'*

Actually there is no built in function similar to string.Format function of .NET is available in SQL server.

There is a function FORMATMESSAGE() in SQL server but it mimics to printf() function of C not string.Format function of .NET.

SELECT FORMATMESSAGE('This is the %s and this is the %s.', 'first variable', 'second variable') AS Result

No,but you can do like this

In html file add this section

<div class="arrow">
</div>

In css you can do like this

p div.arrow {
    content: '';
    position: absolute;
    left:100%;
    width: 10px;
    height: 100%;
    background-color: red;
} 

Hope it will help you

Local storage can store up to 5mb offline data, whereas session can also store up to 5 mb data. But cookies can store only 4kb data in text format.

LOCAl and Session storage data in JSON format, thus easy to parse. But cookies data is in string format.

If we want to rename a specific key in hash then we can do it as follows:
Suppose my hash is my_hash = {'test' => 'ruby hash demo'}
Now I want to replace 'test' by 'message', then:
my_hash['message'] = my_hash.delete('test')

Since the column may be null in the database, the rs.getString() will throw a NullPointerException()

No.

rs.getString will not throw NullPointer if the column is present in the selected result set (SELECT query columns) For a particular record if value for the 'comumn is null in db, you must do something like this -

String myValue = rs.getString("myColumn");
if (rs.wasNull()) {
    myValue = ""; // set it to empty string as you desire.
}

You may want to refer to wasNull() documentation -

From java.sql.ResultSet
boolean wasNull() throws SQLException;

* Reports whether
* the last column read had a value of SQL <code>NULL</code>.
* Note that you must first call one of the getter methods
* on a column to try to read its value and then call
* the method <code>wasNull</code> to see if the value read was
* SQL <code>NULL</code>.
*
* @return <code>true</code> if the last column value read was SQL
*         <code>NULL</code> and <code>false</code> otherwise
* @exception SQLException if a database access error occurs or this method is 
*            called on a closed result set

$(".datepicker").datepicker({maxDate: '0'});

This will set the maxDate to +0 days from the current date (i.e. today). See:

http://api.jqueryui.com/datepicker/#option-maxDate

If you were to do the following:

<li class="active-item" ng-repeat="item in mc.pageData.items | filter: { itemTypeId: 2, itemStatus: 1 } | orderBy : 'listIndex'"
                id="{{item.id}}">
    <span class="item-title">{{preference.itemTitle}}</span>
</li>

...you would not only get items of itemTypeId 2 and itemStatus 1, but you would also get items with itemType 20, 22, 202, 123 and itemStatus 10, 11, 101, 123. This is because the filter: {...} syntax works like a string contains query.

However, if you were to add the : true condition, it would do filter by exact match:

<li class="active-item" ng-repeat="item in mc.pageData.items | filter: { itemTypeId: 2, itemStatus: 1 } : true | orderBy : 'listIndex'"
                id="{{item.id}}">
    <span class="item-title">{{preference.itemTitle}}</span>
</li>

Yep it is here, using _.reduce

var params = [
    { name: 'foo', input: 'bar' },
    { name: 'baz', input: 'zle' }
];

_.reduce(params , function(obj,param) {
 obj[param.name] = param.input
 return obj;
}, {});

In MS Excel, first save your workbook as a Macro Enabled file then go to the Developper Tab and click on Visual Basic. Copy and paste this code in the "ThisWorkbook" Excel Objects. Replace the 2 values of G = and C= by the number of the column containing the values being referenced.

In your case, if the number of the column named "File No" is the first column (namely column 1), replace G=6 by G=1 and C=6 by C-1. Finally click on Macro, Select and Run it. Voila! Works like a charm.

Sub color()
    Dim g As Long
    Dim c As Integer
    Dim colorIt As Boolean

    g = 6
    c = 6
    colorIt = True

    Do While Cells(g, c) <> ""
        test_value = Cells(g, c)
        Do While Cells(g, c) = test_value
            If colorIt Then
                Cells(g, c).EntireRow.Select
                Selection.Interior.ColorIndex = 15
            Else
                Cells(g, c).EntireRow.Select
                Selection.Interior.ColorIndex = x1None
            End If
            g = g + 1
        Loop
        colorIt = Not (colorIt)
    Loop
End Sub

a=[100,200,300,400,500]
def search(b):
 try:
  k=a.index(b)
  return a[k] 
 except ValueError:
    return 'not found'
print(search(500))

it'll return the object if found else it'll return "not found"

If you don't support future dated transactions then something like this might work:

AND oh.tran_date >= trunc(sysdate-1)

Assignment, at its heart, is two steps: tearing down the object's old state and building its new state as a copy of some other object's state.

Basically, that's what the destructor and the copy constructor do, so the first idea would be to delegate the work to them. However, since destruction mustn't fail, while construction might, we actually want to do it the other way around: first perform the constructive part and, if that succeeded, then do the destructive part. The copy-and-swap idiom is a way to do just that: It first calls a class' copy constructor to create a temporary object, then swaps its data with the temporary's, and then lets the temporary's destructor destroy the old state.
Since swap() is supposed to never fail, the only part which might fail is the copy-construction. That is performed first, and if it fails, nothing will be changed in the targeted object.

In its refined form, copy-and-swap is implemented by having the copy performed by initializing the (non-reference) parameter of the assignment operator:

T& operator=(T tmp)
{
    this->swap(tmp);
    return *this;
}

You can use the COALESCE function to automatically return null values as 0. Syntax is as shown below:

SELECT COALESCE(total_amount, 0) from #Temp1

Although there isn't a syntax, you can still get close by using the built-in block comment buttons:

If you're not viewing the Edit toolbar already, right-click on the toolbar and enable the Edit toolbar:

Then, select a block of code and hit the "Comment Block" button; or if it's already commented out, use the "Uncomment Block" button:

Fast and easy!

The structs testing.T and testing.B both have a .Log and .Logf method that sound to be what you are looking for. .Log and .Logf are similar to fmt.Print and fmt.Printf respectively.

See more details here: http://golang.org/pkg/testing/#pkg-index

fmt.X print statements do work inside tests, but you will find their output is probably not on screen where you expect to find it and, hence, why you should use the logging methods in testing.

If, as in your case, you want to see the logs for tests that are not failing, you have to provide go test the -v flag (v for verbosity). More details on testing flags can be found here: https://golang.org/cmd/go/#hdr-Testing_flags

  function omtCallFromAjax(urlVariable)

 </script>

try this it work for me

your $(this).val() has no scope in your ajax call, because its not in change event function scope

May be you implemented that ajax call in your change event itself first, in that case it works fine. but when u created a function and calling that funciton in change event, scope for $(this).val() is not valid.

simply get the value using id selector instead of

$(#CourseSelect).val()

whole code should be like this:

 $(document).ready(function () 
{
    $("#CourseSelect").change(loadTeachers);
    loadTeachers();
});

function loadTeachers()
{
    $.ajax({ type:'GET', url:'/Manage/getTeachers/' + $(#CourseSelect).val(), dataType:'json', cache:false,
        success:function(data)
        { 
            $('#TeacherSelect').get(0).options.length = 0;    

            $.each(data, function(i, teacher) 
            {
                var option = $('<option />');
                option.val(teacher.employeeId);
                option.text(teacher.name);
                $('#TeacherSelect').append(option);
            });
        }, error:function(){ alert("Error while getting results"); }
    });
}

I don't think enough time was paid attention to the schema considerations brought up in the original post. So, here is something to consider for any newbies.

Let's say you went ahead and built this solution. All of your menial values are conctenated into a single value and stored in the database. You are indeed saving [a little] space in your database and some time coding.

Now let's consider that you must perform the frequent and easy task of adding a new checkbox between the current checkboxes 3 & 4. Your development manager, customer, whatever expects this to be a simple change.

So you add the checkbox to the UI (the easy part). Your looping code would already concatenate the values no matter how many checkboxes. You also figure your database field is just a varchar or other string type so it should be fine as well.

What happens when customers or you try to view the data from before the change? You're essentially serializing from left to right. However, now the values after 3 are all off by 1 character. What are you going to do with all of your existing data? Are you going write an application, pull it all back out of the database, process it to add in a default value for the new question position and then store it all back in the database? What happens when you have several new values a week or month apart? What if you move the locations and jQuery processes them in a different order? All your data is hosed and has to be reprocessed again to rearrange it.

The whole concept of NOT providing a tight key-value relationship is ludacris and will wind up getting you into trouble sooner rather than later. For those of you considering this, please don't. The other suggestions for schema changes are fine. Use a child table, more fields in the main table, a question-answer table, etc. Just don't store non-labeled data when the structure of that data is subject to change.

While you have a return value in checkform, it isn't being used anywhere - try using onclick="return checkform()" instead.

You may want to considering replacing this method with onsubmit="return checkform()" in the form tag instead, though both will work for clicking the button.

In one line we can set image with this code

[buttonName setBackgroundImage:[UIImage imageNamed:@"imageName"] forState:UIControlStateNormal];

Because @User and @BiXiC asked for help with UTF-8 here a variation of the solution by @Matthew. (I'm not allowed to comment, so I'm answering.)

import unicodecsv as csv
toCSV = [{'name':'bob','age':25,'weight':200},
         {'name':'jim','age':31,'weight':180}]
keys = toCSV[0].keys()
with open('people.csv', 'wb') as output_file:
    dict_writer = csv.DictWriter(output_file, keys)
    dict_writer.writeheader()
    dict_writer.writerows(toCSV)

I used:

Get-Content c:\FileToAppend_*.log | Out-File -FilePath C:\DestinationFile.log 
-Encoding ASCII -Append

This appended fine. I added the ASCII encoding to remove the nul characters Notepad++ was showing without the explicit encoding.

Use >> to append:

command >> file

Why does it implement its methods? How can it implement its methods when an interface can't contain method body? How can it implement the methods when it extends the other interface and not implement it? What is the purpose of an interface implementing another interface?

Interface does not implement the methods of another interface but just extends them. One example where the interface extension is needed is: consider that you have a vehicle interface with two methods moveForward and moveBack but also you need to incorporate the Aircraft which is a vehicle but with some addition methods like moveUp, moveDown so in the end you have:

public interface IVehicle {
  bool moveForward(int x);
  bool moveBack(int x);
};

and airplane:

public interface IAirplane extends IVehicle {
  bool moveDown(int x);
  bool moveUp(int x);
};

For me the solution was besides using "Ntlm" as credential type, similar as Jeroen K's solution. If I had the permission level I would plus on his post, but let me post my whole code here, which will support both Windows and other credential types like basic auth:

    XxxSoapClient xxxClient = new XxxSoapClient();
    ApplyCredentials(userName, password, xxxClient.ClientCredentials);

    private static void ApplyCredentials(string userName, string password, ClientCredentials clientCredentials)
    {
        clientCredentials.UserName.UserName = userName;
        clientCredentials.UserName.Password = password;
        clientCredentials.Windows.ClientCredential.UserName = userName;
        clientCredentials.Windows.ClientCredential.Password = password;
        clientCredentials.Windows.AllowNtlm = true;
        clientCredentials.Windows.AllowedImpersonationLevel = System.Security.Principal.TokenImpersonationLevel.Impersonation;
    }  

If your WS-RS needs raise an error why not just use the WebApplicationException?

@GET
@Produces({ MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML })
@Path("{id}")
public MyEntity getFoo(@PathParam("id") long id,  @QueryParam("lang")long idLanguage) {

if (idLanguage== 0){
    // No URL parameter idLanguage was sent
    ResponseBuilder builder = Response.status(Response.Status.BAD_REQUEST);
    builder.entity("Missing idLanguage parameter on request");
    Response response = builder.build();
    throw new WebApplicationException(response);
    }
... //other stuff to return my entity
return myEntity;
}

this.comboPortName.Items.AddRange(
    (from qP in System.IO.Ports.SerialPort.GetPortNames()
     orderby System.Text.RegularExpressions.Regex.Replace(qP, "~\\d",
     string.Empty).PadLeft(6, '0')
     select qP).ToArray()
);

Another approach I like to use for application specific filters, is to use a custom read-only property on your component which allows you to encapsulate the filtering logic more cleanly than using a custom pipe (IMHO).

For example, if I want to bind to albumList and filter on searchText:

searchText: "";
albumList: Album[] = [];

get filteredAlbumList() {
    if (this.config.searchText && this.config.searchText.length > 1) {
      var lsearchText = this.config.searchText.toLowerCase();
      return this.albumList.filter((a) =>
        a.Title.toLowerCase().includes(lsearchText) ||
        a.Artist.ArtistName.toLowerCase().includes(lsearchText)
      );
    }
    return this.albumList;
}

To bind in the HTML you can then bind to the read-only property:

<a class="list-group-item"
       *ngFor="let album of filteredAlbumList">
</a>

I find for specialized filters that are application specific this works better than a pipe as it keeps the logic related to the filter with the component.

Pipes work better for globally reusable filters.

<FilesMatch "\.(?i:pdf)$">

  Header set Content-Disposition attachment
</FilesMatch>

There's also a simpler way. If the image is loaded as a resource in the XAML, and the code in question is the codebehind for that XAML:

Here's the resource dictionary for a XAML file - the only line you care about is the ImageBrush with the key "PosterBrush" - the rest of the code is just to show context

<UserControl.Resources>
        <ResourceDictionary>
            <ImageBrush x:Key="PosterBrush" ImageSource="..\Resources\Images\EmptyPoster.jpg" Stretch="UniformToFill"/>

        </ResourceDictionary>
    </UserControl.Resources>

Now, in the code behind, you can just do this

ImageBrush posterBrush = (ImageBrush)Resources["PosterBrush"];

Try the -i flag (or --ignore-errors). The documentation seems to suggest a more robust way to achieve this, by the way:

To ignore errors in a command line, write a - at the beginning of the line's text (after the initial tab). The - is discarded before the command is passed to the shell for execution.

For example,

clean:
  -rm -f *.o

This causes rm to continue even if it is unable to remove a file.

All examples are with rm, but are applicable to any other command you need to ignore errors from (i.e. mkdir).

The first code line, Option Explicit means (in simple terms) that all of your variables have to be explicitly declared by Dim statements. They can be any type, including object, integer, string, or even a variant.

This line: Dim envFrmwrkPath As Range is declaring the variable envFrmwrkPath of type Range. This means that you can only set it to a range.

This line: Set envFrmwrkPath = ActiveSheet.Range("D6").Value is attempting to set the Range type variable to a specific Value that is in cell D6. This could be a integer or a string for example (depends on what you have in that cell) but it's not a range.

I'm assuming you want the value stored in a variable. Try something like this:

Dim MyVariableName As Integer
MyVariableName = ActiveSheet.Range("D6").Value

This assumes you have a number (like 5) in cell D6. Now your variable will have the value.

For simplicity sake of learning, you can remove or comment out the Option Explicit line and VBA will try to determine the type of variables at run time.

Try this to get through this part of your code

Dim envFrmwrkPath As String
Dim ApplicationName As String
Dim TestIterationName As String

Either I don't understand your question, or Enumerable#find is the thing you were looking for.

if you make constructor asynchronous, after creating an object, you may fall into problems like null values instead of instance objects. For instance;

MyClass instance = new MyClass();
instance.Foo(); // null exception here

That's why they don't allow this i guess.

You should use:

protected void btn1_Click(object sender, EventArgs e)
{
    Response.Redirect("otherpage.aspx");
}

I've used another way for a few times. In fact, it is a manual git rebase -i and it is useful when you want to rearrange several commits including squashing or splitting some of them. The main advantage is that you don't have to decide about every commit's destiny at a single moment. You'll also have all Git features available during the process unlike during a rebase. For example, you can display the log of both original and rewritten history at any time, or even do another rebase!

I'll refer to the commits in the following way, so it's readable easily:

C # good commit after a bad one
B # bad commit
A # good commit before a bad one

Your history in the beginning looks like this:

x - A - B - C
|           |
|           master
|
origin/master

We'll recreate it to this way:

x - A - B*- C'
|           |
|           master
|
origin/master

Procedure

git checkout B       # get working-tree to the state of commit B
git reset --soft A   # tell Git that we are working before commit B
git checkout -b rewrite-history   # switch to a new branch for alternative history

Improve your old commit using git add (git add -i, git stash etc.) now. You can even split your old commit into two or more.

git commit           # recreate commit B (result = B*)
git cherry-pick C    # copy C to our new branch (result = C')

Intermediate result:

x - A - B - C 
|    \      |
|     \     master
|      \
|       B*- C'
|           |
|           rewrite-history
|
origin/master

Let's finish:

git checkout master
git reset --hard rewrite-history  # make this branch master

Or using just one command:

git branch -f master  # make this place the new tip of the master branch

That's it, you can push your progress now.

The last task is to delete the temporary branch:

git branch -d rewrite-history

Since @KiritModi 's answer is from 2015, this is the Swift 3.0's version:

func resizeImage(image: UIImage, targetSize: CGSize) -> UIImage {
    let size = image.size

    let widthRatio  = targetSize.width  / image.size.width
    let heightRatio = targetSize.height / image.size.height

    // Figure out what our orientation is, and use that to form the rectangle
    var newSize: CGSize
    if(widthRatio > heightRatio) {
        newSize = CGSize(width: size.width * heightRatio, height: size.height * heightRatio)
    } else {
        newSize = CGSize(width: size.width * widthRatio,  height: size.height * widthRatio)
    }

    // This is the rect that we've calculated out and this is what is actually used below
    let rect = CGRect(x: 0, y: 0, width: newSize.width, height: newSize.height)

    // Actually do the resizing to the rect using the ImageContext stuff
    UIGraphicsBeginImageContextWithOptions(newSize, false, 1.0)
    image.draw(in: rect)
    let newImage = UIGraphicsGetImageFromCurrentImageContext()
    UIGraphicsEndImageContext()

    return newImage!
}

To insert all data from all columns, just use this:

SELECT * INTO #TempTable
FROM OriginalTable

Don't forget to DROP the temporary table after you have finished with it and before you try creating it again:

DROP TABLE #TempTable

I had the same problem, when I use Xcode7.3 it. I solved the problem: I created a new profile select Ad Hoc, and then downloaded to Xcode.That‘s OK!

On 32-bit machines:

cd C:\Windows\System32
regsvr32 mscomctl.ocx
regtlib msdatsrc.tlb

or on 64 bit machines:

cd C:\Windows\SysWOW64
regsvr32 mscomctl.ocx
regtlib msdatsrc.tlb

These need to be run as administrator.

This function returns the column letter for a given column number.

Function Col_Letter(lngCol As Long) As String
    Dim vArr
    vArr = Split(Cells(1, lngCol).Address(True, False), "$")
    Col_Letter = vArr(0)
End Function

testing code for column 100

Sub Test()
    MsgBox Col_Letter(100)
End Sub

With PowerShell on Windows, you can use:

Get-Content ~/.ssh/id_rsa.pub | Set-Clipboard

Yet another answer:

-1 ... requires import
+1 ... is very readable

import operator
a = [1,2,3,4]
b = [10,11,12,13]

list(map(operator.mul, a, b))

outputs [10, 22, 36, 52]

You can use join() to wait for all threads to finish. Keep all objects of threads in the global ArrayList at the time of creating threads. After that keep it in loop like below:

for (int i = 0; i < 10; i++) 
{
    Thread T1 = new Thread(new ThreadTest(i));                
    T1.start();                
    arrThreads.add(T1);
} 

for (int i = 0; i < arrThreads.size(); i++) 
{
    arrThreads.get(i).join(); 
}

First of all, JDK environment variable settings :

e.g) JAVA_HOME -> C:\develop\java\jdk\jdk1.8.0_25 path -> %JAVA_HOME%\bin;

eclipse Window -> preferences -> Gradle -> Arguments -> Worksapce JRE check -> jdk(jdk1.8.0_25) choice

again Run -> gradle build :)

Using Context manager - [ most simple ]

import logging 

class DisableLogger():
    def __enter__(self):
       logging.disable(logging.CRITICAL)
    def __exit__(self, exit_type, exit_value, exit_traceback):
       logging.disable(logging.NOTSET)

Example of use:

with DisableLogger():
    do_something()

If you need a [more COMPLEX] fine-grained solution you can look at AdvancedLogger

AdvancedLogger can be used for fine grained logging temporary modifications

How it works:
Modifications will be enabled when context_manager/decorator starts working and be reverted after

Usage:
AdvancedLogger can be used
- as decorator `@AdvancedLogger()`
- as context manager `with  AdvancedLogger():`

It has three main functions/features:
- disable loggers and it's handlers by using disable_logger= argument
- enable/change loggers and it's handlers by using enable_logger= argument
- disable specific handlers for all loggers, by using  disable_handler= argument

All features they can be used together

Use cases for AdvancedLogger

# Disable specific logger handler, for example for stripe logger disable console
AdvancedLogger(disable_logger={"stripe": "console"})
AdvancedLogger(disable_logger={"stripe": ["console", "console2"]})

# Enable/Set loggers
# Set level for "stripe" logger to 50
AdvancedLogger(enable_logger={"stripe": 50})
AdvancedLogger(enable_logger={"stripe": {"level": 50, "propagate": True}})

# Adjust already registered handlers
AdvancedLogger(enable_logger={"stripe": {"handlers": "console"}

If you are using DbContext and EF v6+, alternatively you can use:

this.context.Database.CommandTimeout = 180;

1. On the top menu bar, open Window -> Show View -> Other
2. In the Show View window, open Maven -> Maven Repositories

3. In the window that appears, right-click on Global Repositories and select Go Into
4. Right-click on "central (http://repo.maven.apache.org/maven2)" and select "Rebuild Index"

• Note that it will take very long to complete the download!!!

5. Once indexing is complete, Right-click on the project -> Maven -> Add Dependency and start typing the name of the project you want to import (such as "hibernate").

• The search results will auto-fill in the "Search Results" box below.

You can make Inheritance Inversion (look it up here: https://medium.com/@franleplant/react-higher-order-components-in-depth-cf9032ee6c3e). That way you have access to instance of the component that you would be wrapping (thus you'll be able to access it's functions)

http://docs.python.org/library/configparser.html

Python's standard library might be helpful in this case.

Thanks Cody, that was very helpful. I've just added an example for guys using the Delegate Command in C#

<PasswordBox x:Name="PasswordBox"
             Grid.Row="1" Grid.Column="1"
             HorizontalAlignment="Left" 
             Width="300" Height="25"
             Margin="6,7,0,7" />
<Button Content="Login"
        Grid.Row="4" Grid.Column="1"
        Style="{StaticResource StandardButton}"
        Command="{Binding LoginCommand}"
        CommandParameter="{Binding ElementName=PasswordBox}"
        Height="31" Width="92"
        Margin="5,9,0,0" />

public ICommand LoginCommand
{
   get
   {
        return new DelegateCommand<object>((args) =>
        {
            // Get Password as Binding not supported for control-type PasswordBox
            LoginPassword = ((PasswordBox) args).Password;

            // Rest of code here
        });
   }
}

Wrap your floating <div>s in a container <div> that uses this cross-browser min-width hack:

.minwidth { min-width:100px; width: auto !important; width: 100px; }

You may also need to set "overflow" but probably not.

This works because:

• The !important declaration, combined with min-width cause everything to stay on the same line in IE7+
• IE6 does not implement min-width, but it has a bug such that width: 100px overrides the !important declaration, causing the container width to be 100px.
