Keep in mind that the copy constructor limits the class type to that of the copy constructor. Consider the example:

// Need to clone person, which is type Person
Person clone = new Person(person);

This doesn't work if person could be a subclass of Person (or if Person is an interface). This is the whole point of clone, is that it can can clone the proper type dynamically at runtime (assuming clone is properly implemented).

Person clone = (Person)person.clone();

or

Person clone = (Person)SomeCloneUtil.clone(person); // See Bozho's answer

Now person can be any type of Person assuming that clone is properly implemented.

As of Jackson 1.6, you can use:

JsonNode node = mapper.valueToTree(map);

or

JsonNode node = mapper.convertValue(object, JsonNode.class);

Here's my solution:

@arr = ['<p>Hello World</p>', '<p>This is a test</p>']
@arr.reduce(:+)
=> <p>Hello World</p><p>This is a test</p>

My guess is that the folder you are trying to add already exists in SVN. You can confirm by checking out the files to a different folder and see if trunk already has the required folder.

With ES6 you can simply do:

 for(const element of Results) {
      element.Active = "false";
 }

Class.isAssignableFrom() - works for interfaces as well. If you don't want that, you'll have to call getSuperclass() and test until you reach Object.

import json

array = '{"fruits": ["apple", "banana", "orange"]}'
data  = json.loads(array)
print data['fruits']
# the print displays:
# [u'apple', u'banana', u'orange']

You had everything you needed. data will be a dict, and data['fruits'] will be a list

I have accomplished this with a hidden iframe. I use perl, not php, so will just give concept, not code solution.

Client sends Ajax request to server, causing the file content to be generated. This is saved as a temp file on the server, and the filename is returned to the client.

Client (javascript) receives filename, and sets the iframe src to some url that will deliver the file, like:

$('iframe_dl').src="/app?download=1&filename=" + the_filename

Server slurps the file, unlinks it, and sends the stream to the client, with these headers:

Content-Type:'application/force-download'
Content-Disposition:'attachment; filename=the_filename'

Works like a charm.

Justin has given you some very fine tips :)

You will also get that error if the cell where you are performing the calculation has an error resulting from a formula.

For example if Cell A1 has #DIV/0! error then you will get "Excel VBA Run-time error '13' Type mismatch" when performing this code

Sheets("Sheet1").Range("A1").Value - 1

I have made some slight changes to your code. Could you please test it for me? Copy the code with the line numbers as I have deliberately put them there.

Seeing as everyone else has already listed most of the other ways to say not equal I will just add:

if not (1) == (1): # This will eval true then false
    # (ie: 1 == 1 is true but the opposite(not) is false)
    print "the world is ending" # This will only run on a if true
elif (1+1) != (2): #second if
    print "the world is ending"
    # This will only run if the first if is false and the second if is true
else: # this will only run if the if both if's are false
    print "you are good for another day"

in this case it is simple switching the check of positive == (true) to negative and vise versa...

You can use max_element to get the maximum value in vector. The max_element returns an iterator to largest value in the range, or last if the range is empty. As an iterator is like pointers (or you can say pointer is a form of iterator), you can use a * before it to get the value. So as per the problem you can get the maximum element in an vector as:

int max=*max_element(cloud.begin(), cloud.end());

It will give you the maximum element in your vector "cloud". Hope it helps.

Beware the leading 00 that can appear in the modulus when using:

openssl rsa -pubin -inform PEM -text -noout < public.key

The example modulus contains 257 bytes rather than 256 bytes because of that 00, which is included because the 9 in 98 looks like a negative signed number.

Hi, you need to put this in form activate, and have an id field named id...

this way it passes until it reaches the one without id (AKA new one)...

INSERT INTO table 2
SELECT * FROM table1/view1

Also you can:

1. Set a breakpoint to pause the execution.
2. The object must be inside the execution scope
3. Move the mouse pointer over the object or variable
4. A yellow tooltip will appear
5. Move the mouse over the tooltip
6. Click over the two little arrows pointing up and down
7. A context menu will pop up
8. Select "Print Description", it will execute a [object description]
9. The description will appear in the console's output

IMHO a little bit hidden and cumbersome...

You need to publish the app before it becomes available for testing.

if you publish the app and the apk is only in "alpha testing" section then it is NOT available to general public, only for activated testers in the alpha section.

EDIT: One additional note: "normal" users will not find your app on Google Play, but also the activated tester can not find the application by using the search box.

Only the direct link to the application package will work. (only for the activated testers).

PhpUnit is an amazing library, but this specific point is a bit frustrating. This is why we can use the turbotesting-php opensource library which has a very convenient assertion method to help us testing exceptions. It is found here:

https://github.com/edertone/TurboTesting/blob/master/TurboTesting-Php/src/main/php/utils/AssertUtils.php

And to use it, we would simply do the following:

AssertUtils::throwsException(function(){

    // Some code that must throw an exception here

}, '/expected error message/');

If the code we type inside the anonymous function does not throw an exception, an exception will be thrown.

If the code we type inside the anonymous function throws an exception, but its message does not match the expected regexp, an exception will also be thrown.

100 characters.

This is the var (variable) in varchar: you only store what you enter (and an extra 2 bytes to store length upto 65535)

If it was char(200) then you'd always store 200 characters, padded with 100 spaces

See the docs: "The CHAR and VARCHAR Types"

Try to use global.foo = bar in index.android.js or index.ios.js, then you can call in other file js.

In C, there's not much difference when used in the startup function of the program (which can be main(), wmain(), _tmain() or the default name used by your compiler).

If you return in main(), control goes back to the _start() function in the C library which originally started your program, which then calls exit() anyways. So it really doesn't matter which one you use.

i just wrote a very fast solution by combining all knowledge gain above

    function pinger($address){
        if(strtolower(PHP_OS)=='winnt'){
            $command = "ping -n 1 $address";
            exec($command, $output, $status);
        }else{
            $command = "ping -c 1 $address";
            exec($command, $output, $status);
        }
        if($status === 0){
            return true;
        }else{
            return false;
        }
    }

In line with the answer given by Denis de Bernardy..

If you want id to be returned afterwards as well and want to insert more things into Table2:

with rows as (
INSERT INTO Table1 (name) VALUES ('a_title') RETURNING id
)
INSERT INTO Table2 (val, val2, val3)
SELECT id, 'val2value', 'val3value'
FROM rows
RETURNING val

If you want the first line and then you want to perform some operation on file this code will helpful.

with open(filename , 'r') as f:
    first_line = f.readline()
    for line in f:
            # Perform some operations

This won't be the answer for everyone, since it is not supported in IE7-, but you could use it and then use an alternate answer for IE7-. It is display: table, display: table-row and display: table-cell. Note that this is not using tables for layout, but styling divs so that things line up nicely with out all the hassle from above. Mine is an html5 app, so it works great.

This article shows an example: http://www.sitepoint.com/table-based-layout-is-the-next-big-thing/

Here is what your stylesheet will look like:

 .container {
    display: table;
    width:100%;
 }

 .left-column {
    display: table-cell;
 }

 .right-column {
    display: table-cell;
    width: 200px;
 }

Ideally, a hashtable is O(1). The problem is if two keys are not equal, however they result in the same hash.

For example, imagine the strings "it was the best of times it was the worst of times" and "Green Eggs and Ham" both resulted in a hash value of 123.

When the first string is inserted, it's put in bucket 123. When the second string is inserted, it would see that a value already exists for bucket 123. It would then compare the new value to the existing value, and see they are not equal. In this case, an array or linked list is created for that key. At this point, retrieving this value becomes O(n) as the hashtable needs to iterate through each value in that bucket to find the desired one.

For this reason, when using a hash table, it's important to use a key with a really good hash function that's both fast and doesn't often result in duplicate values for different objects.

Make sense?

as mentioned above: its not possible to call a css pseudo-class / -element inline. what i now did, is: give your element a unique identifier, f.ex. an id or a unique class. and write a fitting <style> element

<style>#id29:before { content: "*";}</style>
<article id="id29">
  <!-- something -->
</article>

fugly, but what inline css isnt..?

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

It should be just routerLink="/about"

it probably might be due to the mongod.lock file, but if the error persists even after deleting it check the paths in mongo.conf; it might be a simple issue such as the configured log Path or dbPath is not there (check the paths in mongo/conf/mongod.conf and check whether they exists, sometimes mongo cannot in its own create directory structures therefore you might have to create those directories manually before starting mongod).

# Hide grid lines
ax.grid(False)

# Hide axes ticks
ax.set_xticks([])

Note, you need matplotlib>=1.2 for set_zticks() to work.

I'd print out the result of an2.getNodeName() as well for debugging purposes. My guess is that your tree crawling code isn't crawling to the nodes that you think it is. That suspicion is enhanced by the lack of checking for node names in your code.

Other than that, the javadoc for Node defines "getNodeValue()" to return null for Nodes of type Element. Therefore, you really should be using getTextContent(). I'm not sure why that wouldn't give you the text that you want.

Perhaps iterate the children of your tag node and see what types are there?

Tried this code and it works for me:

String xml = "<add job=\"351\">\n" +
             "    <tag>foobar</tag>\n" +
             "    <tag>foobar2</tag>\n" +
             "</add>";
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
ByteArrayInputStream bis = new ByteArrayInputStream(xml.getBytes());
Document doc = db.parse(bis);
Node n = doc.getFirstChild();
NodeList nl = n.getChildNodes();
Node an,an2;

for (int i=0; i < nl.getLength(); i++) {
    an = nl.item(i);
    if(an.getNodeType()==Node.ELEMENT_NODE) {
        NodeList nl2 = an.getChildNodes();

        for(int i2=0; i2<nl2.getLength(); i2++) {
            an2 = nl2.item(i2);
            // DEBUG PRINTS
            System.out.println(an2.getNodeName() + ": type (" + an2.getNodeType() + "):");
            if(an2.hasChildNodes()) System.out.println(an2.getFirstChild().getTextContent());
            if(an2.hasChildNodes()) System.out.println(an2.getFirstChild().getNodeValue());
            System.out.println(an2.getTextContent());
            System.out.println(an2.getNodeValue());
        }
    }
}

Output was:

#text: type (3): foobar foobar
#text: type (3): foobar2 foobar2

The best solution I've found in this is to create a lookup table with the possible values as a primary key, and create a foreign key to the lookup table.

None of the above worked for me, the only one working was

insert into tableName  
select 11, 'BALOO' from sysibm.sysdummy1 union all
select 22, nullif('','') AS nullColumn from sysibm.sysdummy1

The nullif is used since it is not possible to pass null in the select statement otherwise.

Not sure if this works for cells with functions but I found this code elsewhere for single cell entries and modified it for my use. If done properly, you do not need to worry about entering a function in a cell or the file changing the dates to that day's date every time it is opened.

• open Excel
• press "Alt+F11"
• Double-click on the worksheet that you want to apply the change to (listed on the left)
• copy/paste the code below
• adjust the Range(:) input to correspond to the column you will update
• adjust the Offset(0,_) input to correspond to the column where you would like the date displayed (in the version below I am making updates to column D and I want the date displayed in column F, hence the input entry of "2" for 2 columns over from column D)
• hit save
• repeat steps above if there are other worksheets in your workbook that need the same code
• you may have to change the number format of the column displaying the date to "General" and increase the column's width if it is displaying "####" after you make an updated entry

Copy/Paste Code below:

Private Sub Worksheet_Change(ByVal Target As Range)

If Intersect(Target, Range("D:D")) Is Nothing Then Exit Sub
Target.Offset(0, 2) = Date

End Sub

Good luck...

In your example propertyInfo.GetValue(this, null) should work. Consider altering GetNamesAndTypesAndValues() as follows:

public void GetNamesAndTypesAndValues()
{
  foreach (PropertyInfo propertyInfo in allClassProperties)
  {
    Console.WriteLine("{0} [type = {1}] [value = {2}]",
      propertyInfo.Name,
      propertyInfo.PropertyType,
      propertyInfo.GetValue(this, null));
  }
}

assertTrue will fail if the checked value is false, and assertFalse will do the opposite: fail if the checked value is true.

Another thing, your last assertEquals will very likely fail, as it will compare the "Book was already checked out" string with the output of m1.checkOut(b1,p2). It needs a third parameter (the second value to check for equality).

Ctrl+K,Ctrl+R opens the Object Browser in Visual Studio 2010. Find what you're looking for by searching and browsing and filtering the results. See also Ctrl+Alt+J. ^K ^R is better because it puts your caret right in the search box, ready to type your new search, even when the Object Browser is already open.

Set the Browse list on the top left to where you want to look to get started. From there you can use the search box (2nd text box from the top, goes all the way across the Object Browser window) or you can just go through everything from the tree on the left. Searches are temporary but the "selected components" set by the Browse list persists. Set a custom set with the little "..." button just to the right of the list.

Objects, packages, namespaces, types, etc. on the left; fields, methods, constants, etc. on the top right, docstrings on the lower right.

The display mode of a pane can be changed by right-clicking in the empty space of the window; tree organized by assembly/container or by namespace and other preferences.

Items can be right-clicked to find, copy and filter.

For keyboard navigation, use Ctrl+K,Ctrl+R from anywhere to start a new search, Enter to execute the search you just typed or pasted and Ctrl+F6 to make the Object Browser close. ALT+<-- to go back and ALT+--> to go forward through the search history. More can be set; search for "ObjectBrowser" in the keyboard shortcut config.

If the key shortcuts above don't work, Object Browser should be in the View menu somewhere with a different shortcut. If all else fails, search for "ObjectBrowser" under Tools->Options->Environment->Keyboard->"Show commands containing".

13 September 2018 It worked for me when add more types and set universalApk with false to reduce apk size

    abi {
        enable true
        reset()
        include 'x86', 'x86_64', 'armeabi', 'armeabi-v7a', 'mips', 'mips64', 'arm64-v8a'
        universalApk false

As a warning - if you're going to use the following (note the milliseconds instead of minutes):

    SELECT DATEADD(ms, DATEDIFF(ms, GETUTCDATE(), GETDATE()), MyTable.UtcColumn) 
    AS ColumnInLocalTime
    FROM MyTable

Keep in mind that the DATEDIFF part will not always return the same number. So don't use it to compare DateTimes down to milliseconds.

Okay. The same time I was writing down my question one of my colleagues made me aware this is actually HTML5 behavior. See http://dev.w3.org/html5/spec/Overview.html#the-required-attribute

Seems in HTML5 there is a new attribute "required". And Safari 5 already has an implementation for this attribute.

1. In vim, you save a file with :wEnter while in the normal mode (you get to the normal mode by pressing Esc).
2. You close your file with :q while in the normal mode.

You can combine both these actions and do Esc:wqEnter to save the commit and quit vim.

As an alternate to the above, you can also press ZZ while in the normal mode, which will save the file and exit vim. This is also easier for some people as it's the same key pressed twice.

You can use casting:

<?php

$string = "<element><child>Hello World</child></element>";
$xml = new SimpleXMLElement($string);

$text = (string)$xml->child;

$text will be 'Hello World'

I recently discovered a project called OniVim, which is an electron-based front-end for NeoVim that comes with very nice autocomplete for several languages out of the box, and since it's basically just a wrapper around NeoVim, you have the full power of vim at your disposal if the GUI doesn't meet your needs. It's still in early development, but it is rapidly improving and there is a really active community around it. I have been using vim for over 10 years and started giving Oni a test drive a few weeks ago, and while it does have some bugs here and there it hasn't gotten in my way. I would strongly recommend it to new vim users who are still getting their vim-fingers!

For security & other reasons, ruby does not by default include the current directory in the load_path. You may want to check this for more details - Why does Ruby 1.9.2 remove "." from LOAD_PATH, and what's the alternative?

You should be able to access the document in the IFRAME using the following code:

document.getElementById('myframe').contentWindow.document

However, you will not be able to do this if the page in the frame is loaded from a different domain (such as google.com). THis is because of the browser's Same Origin Policy.

with(dfr[dfr$var3 < 155,], plot(var1, var2)) should do the trick.

let url = URL(string: "URLSTRING HERE")
let anyvar =  String(describing: url)

A reproducible example:

the_plot <- function()
{
  x <- seq(0, 1, length.out = 100)
  y <- pbeta(x, 1, 10)
  plot(
    x,
    y,
    xlab = "False Positive Rate",
    ylab = "Average true positive rate",
    type = "l"
  )
}

James's suggestion of using pointsize, in combination with the various cex parameters, can produce reasonable results.

png(
  "test.png",
  width     = 3.25,
  height    = 3.25,
  units     = "in",
  res       = 1200,
  pointsize = 4
)
par(
  mar      = c(5, 5, 2, 2),
  xaxs     = "i",
  yaxs     = "i",
  cex.axis = 2,
  cex.lab  = 2
)
the_plot()
dev.off()

Of course the better solution is to abandon this fiddling with base graphics and use a system that will handle the resolution scaling for you. For example,

library(ggplot2)

ggplot_alternative <- function()
{
  the_data <- data.frame(
    x <- seq(0, 1, length.out = 100),
    y = pbeta(x, 1, 10)
  )

ggplot(the_data, aes(x, y)) +
    geom_line() +
    xlab("False Positive Rate") +
    ylab("Average true positive rate") +
    coord_cartesian(0:1, 0:1)
}

ggsave(
  "ggtest.png",
  ggplot_alternative(),
  width = 3.25,
  height = 3.25,
  dpi = 1200
)

I came here and followed above answer. But mismatch in the Order of data type caused an error. The below description from another answer will come handy.

Are the results above the same as the sequence of columns in your table? because oracle is strict in column orders. this example below produces an error:

create table test1_1790 (
col_a varchar2(30),
col_b number,
col_c date);

create table test2_1790 (
col_a varchar2(30),
col_c date,
col_b number);

select * from test1_1790
union all
select * from test2_1790;

ORA-01790: expression must have same datatype as corresponding expression

As you see the root cause of the error is in the mismatching column ordering that is implied by the use of * as column list specifier. This type of errors can be easily avoided by entering the column list explicitly:

select col_a, col_b, col_c from test1_1790 union all select col_a, col_b, col_c from test2_1790; A more frequent scenario for this error is when you inadvertently swap (or shift) two or more columns in the SELECT list:

select col_a, col_b, col_c from test1_1790
union all
select col_a, col_c, col_b from test2_1790;

OR if the above does not solve your problem, how about creating an ALIAS in the columns like this: (the query is not the same as yours but the point here is how to add alias in the column.)

SELECT id_table_a, 
       desc_table_a, 
       table_b.id_user as iUserID, 
       table_c.field as iField
UNION
SELECT id_table_a, 
       desc_table_a, 
       table_c.id_user as iUserID, 
       table_c.field as iField

What worked for me was:

1. Remove .git/logs/refs/remotes/origin/branch
2. Remove .git/refs/remotes/origin/branch
3. Run git gc --prune=now

This should work :

  curl -i -H "Accept: application/json" 'server:5050/a/c/getName{"param0":"pradeep"}'

use option -i instead of x.

With New-Item you can add the Force parameter

New-Item -Force -ItemType directory -Path foo

Or the ErrorAction parameter

New-Item -ErrorAction Ignore -ItemType directory -Path foo

This worked:

$("#theSelectId").prepend("<option value='' selected='selected'></option>");

Firebug Output:

<select id="theSelectId">
  <option selected="selected" value=""/>
  <option value="volvo">Volvo</option>
  <option value="saab">Saab</option>
  <option value="mercedes">Mercedes</option>
  <option value="audi">Audi</option>
</select>

You could also use .prependTo if you wanted to reverse the order:

?$("<option>", { value: '', selected: true }).prependTo("#theSelectId");???????????

The command is lowercase: touch filename.

Keep in mind that touch will only create a new file if it does not exist! Here's some docs for good measure: http://unixhelp.ed.ac.uk/CGI/man-cgi?touch

If you always want an empty file, one way to do so would be to use:

echo "" > filename

I struggeld for many hours on this. This is my loop to register command line vars. Example : Register.bat /param1:value1 /param2:value2

What is does, is loop all the commandline params, and that set the variable with the proper name to the value.

After that, you can just use set value=!param1! set value2=!param2!

regardless the sequence the params are given. (so called named parameters). Note the !<>!, instead of the %<>%.

SETLOCAL ENABLEDELAYEDEXPANSION

FOR %%P IN (%*) DO (
    call :processParam %%P
)

goto:End

:processParam [%1 - param]

    @echo "processparam : %1"
    FOR /F "tokens=1,2 delims=:" %%G IN ("%1") DO (
        @echo a,b %%G %%H
        set nameWithSlash=%%G
        set name=!nameWithSlash:~1!
        @echo n=!name!
        set value=%%H
        set !name!=!value!
    )
    goto :eof

:End    

Call plt.show() after plt.savefig(fig) and your problem should be solved.

If you will always have the pattern on _b instead of _t you can make it more generic by passing reference to the image itself:

onclick='changeImage(this);'

Then in the function:

function changeImage(img) {
    document.getElementById("img").src = img.src.replace("_t", "_b");
}

IMO this is the cleanest and easiest solution:

$("#first").animate({height: $("#first").get(0).scrollHeight}, 1000 );

Explanation: The DOM already knows from its initial rendering what size the expanded div will have when set to auto height. This property is stored in the DOM node as scrollHeight. We just have to fetch the DOM Element from the jQuery Element by calling get(0) and then we can access the property.

Adding a callback function to set the height to auto allows for greater responsiveness once the animation is complete (credit chris-williams):

$('#first').animate({
    height: $('#first').get(0).scrollHeight
}, 1000, function(){
    $(this).height('auto');
});

Look at Django Poor Man's Cron which is a Django app that makes use of spambots, search engine indexing robots and alike to run scheduled tasks in approximately regular intervals

I ran into this same problem, but in my case, the only thing that had changed is that I had uninstalled Visual Studio 2012 and installed Visual Studio 2013. I opened up our solution, but I kept getting the same The name 'model' does not exist in current context error in every Razor view.

My coworker suggested checking for updates for VS2013. After I installed the VS2013 Update 1, I stopped getting this error.

Why are you combining GET and POST? Use one or the other.

$.ajax({
    type: 'post',
    data: {
        timestamp: timestamp,
        uid: uid
        ...
    }
});

php:

$uid =$_POST['uid'];

Or, just format your request properly (you're missing the ampersands for the get parameters).

url:"getdata.php?timestamp="+timestamp+"&uid="+id+"&uname="+name,

You can use a function comparator without wrapping it like so:

bool comparator(const MyType &lhs, const MyType &rhs)
{
    return [...];
}

std::set<MyType, bool(*)(const MyType&, const MyType&)> mySet(&comparator);

which is irritating to type out every time you need a set of that type, and can cause issues if you don't create all sets with the same comparator.

I think you approach is correct. Historical table should be a copy of the main table without indexes, make sure you have update timestamp in the table as well.

If you try the other approach soon enough you will face problems:

• maintenance overhead
• more flags in selects
• queries slowdown
• growth of tables, indexes

Linq to SQL Like Operator

If you are using Underscore.js or Lodash, there is a function 'omit' that will do it.
http://underscorejs.org/#omit

var thisIsObject= {
    'Cow' : 'Moo',
    'Cat' : 'Meow',
    'Dog' : 'Bark'
};
_.omit(thisIsObject,'Cow'); //It will return a new object

=> {'Cat' : 'Meow', 'Dog' : 'Bark'}  //result

If you want to modify the current object, assign the returning object to the current object.

thisIsObject = _.omit(thisIsObject,'Cow');

With pure JavaScript, use:

delete thisIsObject['Cow'];

Another option with pure JavaScript.

thisIsObject.cow = undefined;

thisIsObject = JSON.parse(JSON.stringify(thisIsObject ));

According to the Quartz-Scheduler Tutorial It should be value="0 0/30 * * * ?"

The field order of the cronExpression is

1.Seconds

2.Minutes

3.Hours

4.Day-of-Month

5.Month

6.Day-of-Week

7.Year (optional field)

Ensure you have at least 6 parameters or you will get an error (year is optional)

I prefer (a != null) so that the syntax matches reference types.

max function is used to get the maximum out of an iterable.

The iterators may be lists, tuples, dict objects, etc. Or even custom objects as in the example you provided.

max(iterable[, key=func]) -> value
max(a, b, c, ...[, key=func]) -> value

With a single iterable argument, return its largest item.
With two or more arguments, return the largest argument.

So, the key=func basically allows us to pass an optional argument key to the function on whose basis is the given iterator/arguments are sorted & the maximum is returned.

lambda is a python keyword that acts as a pseudo function. So, when you pass player object to it, it will return player.totalScore. Thus, the iterable passed over to function max will sort according to the key totalScore of the player objects given to it & will return the player who has maximum totalScore.

If no key argument is provided, the maximum is returned according to default Python orderings.

Examples -

max(1, 3, 5, 7)
>>>7
max([1, 3, 5, 7])
>>>7

people = [('Barack', 'Obama'), ('Oprah', 'Winfrey'), ('Mahatma', 'Gandhi')]
max(people, key=lambda x: x[1])
>>>('Oprah', 'Winfrey')

I find myself a tad amazed at the lack of what I consider the best answer to this question anywhere on the internet. I struggled for many years to find the answer. Many answers online come close, but none really answer it. The real answer is

(cmd & echo.) >2 & (set /p =)<2

The "secret sauce" being the "closely guarded coveted secret" that "echo." sends a CR/LF (ENTER/new line/0x0D0A). Otherwise, what I am doing here is redirecting the output of the first command to the standard error stream. I then redirect the standard error stream into the standard input stream for the "set /p =" command.

Example:

(echo foo & echo.) >2 & (set /p bar=)<2

Based on Why does FtpWebRequest download files from the root directory? Can this cause a 553 error?, I wrote a PowerShell script that enabled to download a file from a FTP-Server via explicit FTP over TLS:

$Username = "USERNAME"
$Password = "PASSWORD"
$LocalFile = "C:\PATH_TO_DIR\FILNAME.EXT"
#e.g. "C:\temp\somefile.txt"
$RemoteFile = "ftp://PATH_TO_REMOTE_FILE"
#e.g. "ftp://ftp.server.com/home/some/path/somefile.txt"

try{ 
    # Create a FTPWebRequest
    $FTPRequest = [System.Net.FtpWebRequest]::Create($RemoteFile)
    $FTPRequest.Credentials = New-Object System.Net.NetworkCredential($Username,$Password)
    $FTPRequest.Method = [System.Net.WebRequestMethods+Ftp]::DownloadFile
    $FTPRequest.UseBinary = $true
    $FTPRequest.KeepAlive = $false
    $FTPRequest.EnableSsl  = $true
    # Send the ftp request
    $FTPResponse = $FTPRequest.GetResponse()
    # Get a download stream from the server response
    $ResponseStream = $FTPResponse.GetResponseStream()
    # Create the target file on the local system and the download buffer
    $LocalFileFile = New-Object IO.FileStream ($LocalFile,[IO.FileMode]::Create)
    [byte[]]$ReadBuffer = New-Object byte[] 1024
    # Loop through the download

    do {
        $ReadLength = $ResponseStream.Read($ReadBuffer,0,1024)
        $LocalFileFile.Write($ReadBuffer,0,$ReadLength)
    }
    while ($ReadLength -ne 0)
}catch [Exception]
{
    $Request = $_.Exception
    Write-host "Exception caught: $Request"
}

How to figure it out

Start with npm root -- it will show you the root folder for NPM packages for the current user. Add -g and you get a global folder. Don't forget to substract node_modules.

Use npm config / npm config -g and check that it'd create you a new .npmrc / npmrc file for you.

Tested on Windows 10 Pro, NPM v.6.4.1:

Global NPM config

C:\Users\%username%\AppData\Roaming\npm\etc\npmrc

Per-user NPM config

C:\Users\%username%\.npmrc

Built-in NPM config

C:\Program Files\nodejs\node_modules\npm\npmrc

References:

• https://docs.npmjs.com/files/npmrc
• https://docs.npmjs.com/misc/config
• https://docs.npmjs.com/cli/root.html

You are probably not assigning it after doing the replacement or replacing the wrong thing. Try :

String haystack = "abcd=0; efgh=1";
String result = haystack.replaceAll("abcd","dddd");

I do this on the server-side. That is, the form always submits to the same target, but I've got a server-side script who is responsible for redirecting to the appropriate location depending on what button was pressed.

If you have multiple buttons, such as

<form action="mypage" method="get">

  <input type="submit" name="retry" value="Retry" />
  <input type="submit" name="abort" value="Abort" />

</form>

Note : I used GET, but it works for POST too

Then you can easily determine which button was pressed - if the variable retry exists and has a value then retry was pressed, and if the variable abort exists and has a value then abort was pressed. This knowledge can then be used to redirect to the appropriate place.

This method needs no Javascript.

Note : that some browsers are capable of submitting a form without pressing any buttons (by pressing enter). Non-standard as this is, you have to account for it, by having a clear default action and activating that whenever no buttons were pressed. In other words, make sure your form does something sensible (whether that's displaying a helpful error message or assuming a default) when someone hits enter in a different form element instead of clicking a submit button, rather than just breaking.

The accepted answer works like a charm unless you're applying it to a vector. Since a vector is non-recursive, you'll get an error like this

$ operator is invalid for atomic vectors

You can use [ in that case

foo[order(foo["V1"]),]

the Perl cookbook contains several iterations of a script "pmdesc" that does what you want. Google-search for "Perl Cookbook pmdesc" and you'll find articles on other Q&A Sites, several code listings on the net, a discussion of the solution, and even some refinements.

The server should respond with the correct MIME Type for JSONP application/javascript and your request should tell jQuery you are loading JSONP dataType: 'jsonp'

Please see this answer for further details ! You can also have a look a this one as it explains why loading .js file with text/plain won't work.

Something like this should do the trick

<select id="leave" onchange="leaveChange()">
  <option value="5">Get Married</option>
  <option value="100">Have a Baby</option>
  <option value="90">Adopt a Child</option>
  <option value="15">Retire</option>
  <option value="15">Military Leave</option>
  <option value="15">Medical Leave</option>
</select>

<div id="message"></div>

Javascript

function leaveChange() {
    if (document.getElementById("leave").value != "100"){
        document.getElementById("message").innerHTML = "Common message";
    }     
    else{
        document.getElementById("message").innerHTML = "Having a Baby!!";
    }        
}

A shorter version and more general could be

  <option value="5">Get Married</option>
  <option value="100">Have a Baby</option>
  <option value="90">Adopt a Child</option>
  <option value="15">Retire</option>
  <option value="15">Military Leave</option>

You can use !setup.py install to do that.

Colab is just like a Jupyter notebook. Therefore, we can use the ! operator here to install any package in Colab. What ! actually does is, it tells the notebook cell that this line is not a Python code, its a command line script. So, to run any command line script in Colab, just add a ! preceding the line.

For example: !pip install tensorflow. This will treat that line (here pip install tensorflow) as a command prompt line and not some Python code. However, if you do this without adding the ! preceding the line, it'll throw up an error saying "invalid syntax".

But keep in mind that you'll have to upload the setup.py file to your drive before doing this (preferably into the same folder where your notebook is).

Hope this answers your question :)

There's another way if you don't want to have older Java versions installed you can do the following:

1) Download the iReport-5.6.0.zip from https://sourceforge.net/projects/ireport/files/iReport/iReport-5.6.0/

2) Download jre-7u67-windows-x64.tar.gz (the one packed in a tar) from https://www.oracle.com/technetwork/java/javase/downloads/java-archive-downloads-javase7-521261.html

3) Extract the iReport and in the extracted folder that contains the bin and etc folders throw in the jre. For example if you unpack twice the jre-7u67-windows-x64.tar.gz you end up with a folder named jre1.7.0_67. Put that folder in the iReport-5.6.0 directory:

and then go into the etc folder and edit the file ireport.conf and add the following line into it:

For Windows jdkhome=".\jre1.7.0_67"

For Linux jdkhome="./jre1.7.0_67"

Note : jre version may change! according to your download of 1.7

now if you run the ireport_w.exe from the bin folder in the iReport directory it should load just fine.

Tried all the answers but none worked. Maybe it's because I'm appending and removing childs before saving the XML. After a lot of googling found this comment in the php documentation. I only had to reload the resulting XML to make it work.

$outXML = $xml->saveXML(); 
$xml = new DOMDocument(); 
$xml->preserveWhiteSpace = false; 
$xml->formatOutput = true; 
$xml->loadXML($outXML); 
$outXML = $xml->saveXML(); 

The correct answer (as of Dec 2018) is... you can't. Upgrading conda install python=3.6 may work, but it might not if you have packages that are necessary, but cannot be uninstalled.

Anaconda uses a default environment named base and you cannot create a new (e.g. python 3.6) environment with the same name. This is intentional. If you want your base Anaconda to be python 3.6, the right way to do this is to install Anaconda for python 3.6. As a package manager, the goal of Anaconda is to make different environments encapsulated, hence why you must source activate into them and why you can't just quietly switch the base package at will as this could lead to many issues on production systems.

I know the question is for JUnit4, but if you happen to be stuck at JUnit3, you could create a short utility function like that:

private void assertArrayEquals(Object[] esperado, Object[] real) {
    assertEquals(Arrays.asList(esperado), Arrays.asList(real));     
}

In JUnit3, this is better than directly comparing the arrays, since it will detail exactly which elements are different.

DELETE FROM table WHERE edit_user IS NULL;

Following up on the comment ron posted, here is the detailed solution. Let's say you have registered a repeating alarm with a pending intent like this:

Intent intent = new Intent("com.my.package.MY_UNIQUE_ACTION");
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, 
                                      intent, PendingIntent.FLAG_UPDATE_CURRENT);
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.add(Calendar.MINUTE, 1);

AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), 1000 * 60, pendingIntent);

The way you would check to see if it is active is to:

boolean alarmUp = (PendingIntent.getBroadcast(context, 0, 
        new Intent("com.my.package.MY_UNIQUE_ACTION"), 
        PendingIntent.FLAG_NO_CREATE) != null);

if (alarmUp)
{
    Log.d("myTag", "Alarm is already active");
}

The key here is the FLAG_NO_CREATE which as described in the javadoc: if the described PendingIntent **does not** already exists, then simply return null (instead of creating a new one)

That's an old question, I know. But, according to me, it is missing proper answer.

The actual / optimal workflow here would be to incorporate SVN's post-commit hook so it triggers Jenkins job after the actual commit is issued only, not in any other case. This way you avoid unneeded polls on your SCM system.

You may find the following links interesting:

• Jenkins Wiki's post-commit hook description on Subversion Plugin's doc-site. Here you find documented example of the script you are interested in.
• Hook-scripts contrib directory in the source of official Apache Foundation's Subversion's source control repository.
• Similar question on StackOverflow.

In case of my setup in the corp's SVN server, I utilize the following (censored) script as a post-commit hook on the subversion server side:

#!/bin/sh

# POST-COMMIT HOOK

REPOS="$1"
REV="$2"
#TXN_NAME="$3"
LOGFILE=/var/log/xxx/svn/xxx.post-commit.log

MSG=$(svnlook pg --revprop $REPOS svn:log -r$REV)
JENK="http://jenkins.xxx.com:8080/job/xxx/job/xxx/buildWithParameters?token=xxx&username=xxx&cause=xxx+r$REV"
JENKtest="http://jenkins.xxx.com:8080/view/all/job/xxx/job/xxxx/buildWithParameters?token=xxx&username=xxx&cause=xxx+r$REV"

echo post-commit $* >> $LOGFILE 2>&1

# trigger Jenkins job - xxx
svnlook changed $REPOS -r $REV | cut -d' ' -f4 | grep -qP "branches/xxx/xxx/Source"
if test 0 -eq $? ; then
        echo $(date) - $REPOS - $REV: >> $LOGFILE
        svnlook changed $REPOS -r $REV | cut -d' ' -f4 | grep -P "branches/xxx/xxx/Source" >> $LOGFILE 2>&1

fi

# trigger Jenkins job - xxxx
svnlook changed $REPOS -r $REV | cut -d' ' -f4 | grep -qP "branches/xxx_TEST"
if test 0 -eq $? ; then
        echo $(date) - $REPOS - $REV: >> $LOGFILE
        svnlook changed $REPOS -r $REV | cut -d' ' -f4 | grep -P "branches/xxx_TEST" >> $LOGFILE 2>&1

exit 0

By design it is to be done this way:

I prefer to abuse ActiveSupport::JSON. Their approach is to convert the hash to yaml and then load it. Unfortunately the conversion to yaml isn't simple and you'd probably want to borrow it from AS if you don't have AS in your project already.

We also have to convert any symbols into regular string-keys as symbols aren't appropriate in JSON.

However, its unable to handle hashes that have a date string in them (our date strings end up not being surrounded by strings, which is where the big issue comes in):

string = '{'last_request_at' : 2011-12-28 23:00:00 UTC }' ActiveSupport::JSON.decode(string.gsub(/:([a-zA-z])/,'\\1').gsub('=>', ' : '))

Would result in an invalid JSON string error when it tries to parse the date value.

Would love any suggestions on how to handle this case

Method overloading deals with the notion of having two or more methods in the same class with the same name but different arguments.

void foo(int a)
void foo(int a, float b)

Method overriding means having two methods with the same arguments, but different implementations. One of them would exist in the parent class, while another will be in the derived, or child class. The @Override annotation, while not required, can be helpful to enforce proper overriding of a method at compile time.

class Parent {
    void foo(double d) {
        // do something
    }
}

class Child extends Parent {

    @Override
    void foo(double d){
        // this method is overridden.  
    }
}

As another guy described here, all you need to do is add

DATE is a reserved keyword in Oracle, so I'm using column-name your_date instead.

If you have an index on your_date, I would use

WHERE your_date >= TO_DATE('2010-08-03', 'YYYY-MM-DD')
  AND your_date <  TO_DATE('2010-08-04', 'YYYY-MM-DD')

or BETWEEN:

WHERE your_date BETWEEN TO_DATE('2010-08-03', 'YYYY-MM-DD')
                    AND TO_DATE('2010-08-03 23:59:59', 'YYYY-MM-DD HH24:MI:SS')

If there is no index or if there are not too many records

WHERE TRUNC(your_date) = TO_DATE('2010-08-03', 'YYYY-MM-DD')

should be sufficient. TRUNC without parameter removes hours, minutes and seconds from a DATE.

If performance really matters, consider putting a Function Based Index on that column:

CREATE INDEX trunc_date_idx ON t1(TRUNC(your_date));

If we want partial match just like contains, we can chain the contain call like this :

def getSelectedTablesRows2(allTablesInfoDF: DataFrame, tableNames: Seq[String]): DataFrame = {

    val tableFilters = tableNames.map(_.toLowerCase()).map(name => lower(col("table_name")).contains(name))
    val finalFilter = tableFilters.fold(lit(false))((accu, newTableFilter) => accu or newTableFilter)
    allTablesInfoDF.where(finalFilter)

  }

When you have multiple if conditions, numpy.select is the way to go:

In [4102]: import numpy as np
In [4098]: conditions = [df.A.eq(df.B), df.A.gt(df.B), df.A.lt(df.B)]
In [4096]: choices = [0, 1, -1]

In [4100]: df['C'] = np.select(conditions, choices)

In [4101]: df
Out[4101]: 
   A  B  C
a  2  2  0
b  3  1  1
c  1  3 -1

This issue can happen not only in eclipse but also in any of the text-editor.

On windows systems, windows-10 in my case, this issue arose when the shift and insert key was pressed in tandem unintentionally which takes the user to the overwrite mode.

To get back to insert mode you need to press shift and insert in tandem again.

You don't need jQuery to create a Script DOM Element. It can be done with vanilla ES6 like so:

const script = "console.log('Did it work?')"
new Promise((resolve, reject) => {
  (function(i,s,o,g,r,a,m){
      a=s.createElement(o),m=s.getElementsByTagName(o)[0];
      a.innerText=g;
      a.onload=r;m.parentNode.insertBefore(a,m)}
  )(window,document,'script',script, resolve())
}).then(() => console.log('Sure did!'))

It doesn't need to be wrapped in a Promise, but doing so allows you to resolve the promise when the script loads, helping prevent race conditions for long-running scripts.

My company does the same thing for a number of customers where we host a web site for them although in our case it's xyz.company.com rather than www.company.com. We do get them to set the A record on xyz.company.com to point to an IP address we allocate them.

As to how you could cope with a change in IP address I don't think there is a perfect solution. Some ideas are:

• Use a NAT or IP load balancer and give your customers an IP address belonging to it. If the IP address of the web server needs to change you could make an update on the NAT or load balancer,

• Offer a DNS hosting service as well and get your customers to host their domain with you so that you'd be in a position to update the A records,

• Get your customers to set their A record up to one main web server and use a HTTP redirect for each customer's web requests.

When pinging two systems, by default SSH is enabled (if you have connected via putty or terminal.) To allow ping, I added the security group for each of the instance (inbound).

Try this

Simple way

 Intent intent=new Intent(Current_Activity.this,Current_Activity.class);
    startActivity(intent);
    finish();

run pod install inside ios folder then go back to root folder and run npx react-native run-ios

The Decision between Member and Non-member

The binary operators = (assignment), [] (array subscription), -> (member access), as well as the n-ary () (function call) operator, must always be implemented as member functions, because the syntax of the language requires them to.

Other operators can be implemented either as members or as non-members. Some of them, however, usually have to be implemented as non-member functions, because their left operand cannot be modified by you. The most prominent of these are the input and output operators << and >>, whose left operands are stream classes from the standard library which you cannot change.

For all operators where you have to choose to either implement them as a member function or a non-member function, use the following rules of thumb to decide:

1. If it is a unary operator, implement it as a member function.
2. If a binary operator treats both operands equally (it leaves them unchanged), implement this operator as a non-member function.
3. If a binary operator does not treat both of its operands equally (usually it will change its left operand), it might be useful to make it a member function of its left operand’s type, if it has to access the operand's private parts.

Of course, as with all rules of thumb, there are exceptions. If you have a type

enum Month {Jan, Feb, ..., Nov, Dec}

and you want to overload the increment and decrement operators for it, you cannot do this as a member functions, since in C++, enum types cannot have member functions. So you have to overload it as a free function. And operator<() for a class template nested within a class template is much easier to write and read when done as a member function inline in the class definition. But these are indeed rare exceptions.

(However, if you make an exception, do not forget the issue of const-ness for the operand that, for member functions, becomes the implicit this argument. If the operator as a non-member function would take its left-most argument as a const reference, the same operator as a member function needs to have a const at the end to make *this a const reference.)

Continue to Common operators to overload.

This is offtopic here but the people over at CodeReview are more than happy to help you.

I strongly suggest you to do so, there are several things that need attention in your code. Likewise I suggest that you do start reading tutorials since there is really no good reason not to do so.

Lists:

As you said yourself: you need a list of items. The way it is now you only store a reference to one item. Lucky there is exactly that to hold a group of related objects: a List.

Lists are very straightforward to use but take a look at the related documentation anyway.

A very simple example to keep multiple bikes in a list:

List<Motorbike> bikes = new List<Motorbike>();

bikes.add(new Bike { make = "Honda", color = "brown" });
bikes.add(new Bike { make = "Vroom", color = "red" });

And to iterate over the list you can use the foreach statement:

foreach(var bike in bikes) {
     Console.WriteLine(bike.make);
}

System.out.print(a + "" + b + "" + c);

In my case the problem was that both port 80 and 443 were in use: Steps to use to fix it are :

1. Open xampp and click on config button
2. Now click on ( Appache )httpd.conf (Open in notepad or other editor)
3. Now click ctrl + h.
4. Find 80 and replace with 8080
5. Now save and now click on Appache(httpd-ssl.conf).
6. Now find 443 and replace with 4430.
7. Now your xampp must be working fine as both these code are never in use by other programs on your system.

Now your localhost will be available as localhost:8080

Another trick for getting sequential pieces (beyond the seq solution already mentioned) is to use a short logical vector and use vector recycling:

foo[ c( rep(FALSE, 5), TRUE ) ]

I resolved my trouble in correcting the "Additional Library Directory", this one was wrong in indicating "$(SolutionDir)\Release", I changed it in "$(SolutionDir)\$(IntDir)"

To correct it, open your project properties -> Configuration Properties -> Linker -> General -> Additional Library Directory

I hope this will help some poeples with the same trouble ;)

Try the following code for instance:

working code in jsfiddle.net

For textArea, use this:

<textarea id="txtBox"></textarea>
...
...

For textBox, use this:

<input type="text" id="txtBox"/>
<br>
<input type="text" id="counterBox"/>
<script>
 var txtBoxRef = document.querySelector("#txtBox");
 var counterRef = document.querySelector("#counterBox");
 txtBoxRef.addEventListener("keydown",function(){
  var remLength = 0;
  remLength = 160 - parseInt(txtBoxRef.value.length);
  if(remLength < 0)
   {
    txtBoxRef.value = txtBoxRef.value.substring(0, 160);
    return false;
   }
  counterRef.value = remLength + " characters remaining...";
 },true);
</script>

Hope this Helps!

Your problem stems from reading from and writing to the same file. Rather than opening fileToSearch for writing, open an actual temporary file and then after you're done and have closed tempFile, use os.rename to move the new file over fileToSearch.

Unfortunately, combining multiple entity contexts into a single named connection isn't possible. If you want to use named connection strings from a .config file to define your Entity Framework connections, they will each have to have a different name. By convention, that name is typically the name of the context:

<add name="ModEntity" connectionString="metadata=res://*/ModEntity.csdl|res://*/ModEntity.ssdl|res://*/ModEntity.msl;provider=System.Data.SqlClient;provider connection string=&quot;Data Source=SomeServer;Initial Catalog=SomeCatalog;Persist Security Info=True;User ID=Entity;Password=SomePassword;MultipleActiveResultSets=True&quot;" providerName="System.Data.EntityClient" />
<add name="Entity" connectionString="metadata=res://*/Entity.csdl|res://*/Entity.ssdl|res://*/Entity.msl;provider=System.Data.SqlClient;provider connection string=&quot;Data Source=SOMESERVER;Initial Catalog=SOMECATALOG;Persist Security Info=True;User ID=Entity;Password=Entity;MultipleActiveResultSets=True&quot;" providerName="System.Data.EntityClient" />

However, if you end up with namespace conflicts, you can use any name you want and simply pass the correct name to the context when it is generated:

var context = new Entity("EntityV2");

Obviously, this strategy works best if you are using either a factory or dependency injection to produce your contexts.

Another option would be to produce each context's entire connection string programmatically, and then pass the whole string in to the constructor (not just the name).

// Get "Data Source=SomeServer..."
var innerConnectionString = GetInnerConnectionStringFromMachinConfig();
// Build the Entity Framework connection string.
var connectionString = CreateEntityConnectionString("Entity", innerConnectionString);
var context = new EntityContext(connectionString);

How about something like this:

Type contextType = typeof(test_Entities);
string innerConnectionString = ConfigurationManager.ConnectionStrings["Inner"].ConnectionString;
string entConnection = 
    string.Format(
        "metadata=res://*/{0}.csdl|res://*/{0}.ssdl|res://*/{0}.msl;provider=System.Data.SqlClient;provider connection string=\"{1}\"",
        contextType.Name,
        innerConnectionString);
object objContext = Activator.CreateInstance(contextType, entConnection);
return objContext as test_Entities; 

... with the following in your machine.config:

<add name="Inner" connectionString="Data Source=SomeServer;Initial Catalog=SomeCatalog;Persist Security Info=True;User ID=Entity;Password=SomePassword;MultipleActiveResultSets=True" providerName="System.Data.SqlClient" />

This way, you can use a single connection string for every context in every project on the machine.

BufferedReader br;
FileInputStream fin;
try {
    fin = new FileInputStream(fileName);
    br = new BufferedReader(new InputStreamReader(fin));

    /*Path pathToFile = Paths.get(fileName);
    br = Files.newBufferedReader(pathToFile,StandardCharsets.US_ASCII);*/

    String line = br.readLine();
    while (line != null) {
        String[] attributes = line.split(",");
        Movie movie = createMovie(attributes);
        movies.add(movie);
        line = br.readLine();
    }
    fin.close();
    br.close();
} catch (FileNotFoundException e) {
    System.out.println("Your Message");
} catch (IOException e) {
    System.out.println("Your Message");
}

It works for me. Hope It will help you too.

This only works with 64 bit version of Java. Go to Control Panel and click on the Java icon. On the small window of Java Control Panel, click on the Java menu bar and then click on view button.

If you have two Java platforms, disable the previous version of Java, then click on Runtime parameters text field and write -Xmx1024m or less than RAM size. Don't increase heap size equal to RAM otherwise your system will crash.

Alright, this doesn't apply to the OP's exact situation, but for anyone like myself who comes here facing a similar issue, figure I should throw this out there-- maybe save a headache or two.

If you're using an non-standard "button" to ensure the submit event isn't called:

<form>
  <input type="hidden" name="hide" value="1">
  <a href="#" onclick="submitWithChecked(this.form)">Hide Selected</a>
 </form>

Then, when you try to access this.form in the script, it's going to come up undefined. As I discovered, apparently anchor elements don't have same access to a parent form element the way your standard form elements do.

In such cases, (again, assuming you are intentionally avoiding the submit event for the time-being), you can use a button with type="button"

<form>
  <input type="hidden" name="hide" value="1">
  <button type="button" onclick="submitWithChecked(this.form)">Hide Selected</a>
 </form>

(Addendum 2020: All these years later, I think the more important lesson to take away from this is to check your input. If my function had bothered to check that the argument it received was actually a form element, the problem would have been much easier to catch.)

In newer versions of Qt Creator (Currently using 4.4.1), you can follow these simple steps:
Tools > Options > Environment > Interface

Here you can change the theme to Flat Dark.

It will change the whole Qt Creator theme, not just the editor window.

i think it should be

select convert(varchar(10),StandardCost) +'S' from DimProduct where ProductKey = 212

or

select cast(StandardCost as varchar(10)) + 'S' from DimProduct where ProductKey = 212

I am no expert at this (and this page was very helpful along with http://mywiki.wooledge.org/UsingFind)

Just noticed -path is for a path that fully matches the string/path that comes just after find (. in theses examples) where as -name matches all basenames.

find . -path ./.git  -prune -o -name file  -print

blocks the .git directory in your current directory ( as your finding in . )

find . -name .git  -prune -o -name file  -print

blocks all .git subdirectories recursively.

Note the ./ is extremely important!! -path must match a path anchored to . or whatever comes just after find if you get matches with out it (from the other side of the or '-o') there probably not being pruned! I was naively unaware of this and it put me of using -path when it is great when you don't want to prune all subdirectory with the same basename :D

Other than the append function, if by "multiple values" you mean another list, you can simply concatenate them like so.

>>> a = [1,2,3]
>>> b = [4,5,6]
>>> a + b
[1, 2, 3, 4, 5, 6]

Additionally for what was said, if you want integer powers of two, then 1 << x (or 1L << x) is a faster way to calculate 2^x than Math.pow(2,x) or a multiplication loop, and is guaranteed to give you an int (or long) result.

It only uses the lowest 5 (or 6) bits of x (i.e. x & 31 (or x & 63)), though, shifting between 0 and 31 (or 63) bits.

As mentioned in other answers, the Panel generates a <div> in HTML, while the PlaceHolder does not. But there are a lot more reasons why you could choose either one.

Why a PlaceHolder?

Since it generates no tag of it's own you can use it safely inside other element that cannot contain a <div>, for example:

<table>
    <tr>
        <td>Row 1</td>
    </tr>
    <asp:PlaceHolder ID="PlaceHolder1" runat="server"></asp:PlaceHolder>
</table>

You can also use a PlaceHolder to control the Visibility of a group of Controls without wrapping it in a <div>

<asp:PlaceHolder ID="PlaceHolder1" runat="server" Visible="false">
    <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
    <br />
    <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
</asp:PlaceHolder>

Why a Panel

It generates it's own <div> and can also be used to wrap a group of Contols. But a Panel has a lot more properties that can be useful to format it's content:

<asp:Panel ID="Panel1" runat="server" Font-Bold="true"
    BackColor="Green" ForeColor="Red" Width="200"
    Height="200" BorderColor="Black" BorderStyle="Dotted">
    Red text on a green background with a black dotted border.
</asp:Panel>

But the most useful feature is the DefaultButton property. When the ID matches a Button in the Panel it will trigger a Form Post with Validation when enter is pressed inside a TextBox. Now a user can submit the Form without pressing the Button.

<asp:Panel ID="Panel1" runat="server" DefaultButton="Button1">
    <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
    <br />
    <asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server"
        ErrorMessage="Input is required" ValidationGroup="myValGroup"
        Display="Dynamic" ControlToValidate="TextBox1"></asp:RequiredFieldValidator>
    <br />
    <asp:Button ID="Button1" runat="server" Text="Button" ValidationGroup="myValGroup" />
</asp:Panel>

Try the above snippet by pressing enter inside TextBox1

You could use the same mechanism as git submodule init uses itself, namely, look at .gitmodules. This files enumerates each submodule path and the URL it refers to.

For example, from root of repository, cat .gitmodules will print contents to the screen (assuming you have cat).

Because .gitmodule files have the Git configuration format, you can use git config to parse those files:

git config --file .gitmodules --name-only --get-regexp path

Would show you all submodule entries, and with

git config --file .gitmodules --get-regexp path | awk '{ print $2 }'

you would only get the submodule path itself.

You want huge?

Here's a small table: create table foo (id int not null primary key auto_increment, crap char(2000));

insert into foo(crap) values ('');

-- each time you run the next line, the number of rows in foo doubles. insert into foo( crap ) select * from foo;

run it twenty more times, you have over a million rows to play with.

Yes, if he's looking for looks of relations to navigate, this is not the answer. But if by huge he means to test performance and his ability to optimize, this will do it. I did exactly this (and then updated with random values) to test an potential answer I had for another question. (And didn't answer it, because I couldn't come up with better performance than what that asker had.)

Had he asked for "complex", I'd have gien a differnt answer. To me,"huge" implies "lots of rows".

Because you don't need huge to play with tables and relations. Consider a table, by itself, with no nullable columns. How many different kinds of rows can there be? Only one, as all columns must have some value as none can be null.

Every nullable column multiples by two the number of different kinds of rows possible: a row where that column is null, an row where it isn't null.

Now consider the table, not in isolation. Consider a table that is a child table: for every child that has an FK to the parent, that, is a many-to-one, there can be 0, 1 or many children. So we multiply by three times the count we got in the previous step (no rows for zero, one for exactly one, two rows for many). For any grandparent to which the parent is a many, another three.

For many-to-many relations, we can have have no relation, a one-to-one, a one-to-many, many-to-one, or a many-to-many. So for each many-to-many we can reach in a graph from the table, we multiply the rows by nine -- or just like two one-to manys. If the many-to-many also has data, we multiply by the nullability number.

Tables that we can't reach in our graph -- those that we have no direct or indirect FK to, don't multiply the rows in our table.

By recursively multiplying the each table we can reach, we can come up with the number of rows needed to provide one of each "kind", and we need no more than those to test every possible relation in our schema. And we're nowhere near huge.

I wrote a quick and easy python script to include in my bash script.

For example, your ini file is called food.ini and in the file you can have some sections and some lines:

[FRUIT]
Oranges = 14
Apples = 6

Copy this small 6 line Python script and save it as configparser.py

#!/usr/bin/python
import configparser
import sys
config = configparser.ConfigParser()
config.read(sys.argv[1])
print config.get(sys.argv[2],sys.argv[3])

Now, in your bash script you could do this for example.

OrangeQty=$(python configparser.py food.ini FRUIT Oranges)

or

ApplesQty=$(python configparser.py food.ini FRUIT Apples)
echo $ApplesQty

This presupposes:

1. you have Python installed
2. you have the configparser library installed (this should come with a std python installation)

Hope it helps :¬)

I found a faster way of embedding:

• Just copy the link.
• Paste the link and remove the "?s=19" part and add "/video/1"
• That's it.

Avoid direct references to '@@ERROR'. It's a flighty little thing that can be lost.

Declare @ErrorCode int;
... perform stuff ...
Set @ErrorCode = @@ERROR;
... other stuff ...
if @ErrorCode ...... 

You can using SXSSFWorkbook implementation of Workbook, if you use style in your excel ,You can caching style by Flyweight Pattern to improve your performance.

Example: button.titleLabel?.font = UIFont(name: "HelveticaNeue-Bold", size: 12)

• If you want to use defaul font from it's own family, use for example: "HelveticaNeue"
• If you want to specify family font, use for example: "HelveticaNeue-Bold"

This might be helpful for whoever else faces this problem. I finally figured out a solution. Turns out, even if we use the inline for "content-disposition" and specify a file name, the browsers still do not use the file name. Instead browsers try and interpret the file name based on the Path/URL.

You can read further on this URL: Securly download file inside browser with correct filename

This gave me an idea, I just created my URL route that would convert the URL and end it with the name of the file I wanted to give the file. So for e.g. my original controller call just consisted of passing the Order Id of the Order being printed. I was expecting the file name to be of the format Order{0}.pdf where {0} is the Order Id. Similarly for quotes, I wanted Quote{0}.pdf.

In my controller, I just went ahead and added an additional parameter to accept the file name. I passed the filename as a parameter in the URL.Action method.

I then created a new route that would map that URL to the format: http://localhost/ShoppingCart/PrintQuote/1054/Quote1054.pdf

routes.MapRoute("", "{controller}/{action}/{orderId}/{fileName}",
                new { controller = "ShoppingCart", action = "PrintQuote" }
                , new string[] { "x.x.x.Controllers" }
            );

This pretty much solved my issue. Hoping this helps someone!

try this.

if (ViewState["CurrentTable"] != null)
            {
                DataTable dtCurrentTable = (DataTable)ViewState["CurrentTable"];
                DataRow drCurrentRow = null;
                if (dtCurrentTable.Rows.Count > 0)
                {

                    {

LocalLinks now seems to be obsolete.

LocalExplorer seems to have taken it's place and provides similar functionality:

https://chrome.google.com/webstore/detail/local-explorer-file-manag/eokekhgpaakbkfkmjjcbffibkencdfkl/reviews?hl=en

It's basically a chrome plugin that replaces file:// links with localexplorer:// links, combined with an installable protocol handler that intercepts localexplorer:// links.

Best thing I can find available right now, I have no affiliation with the developer.

This one, from kristopherjohnson is heaps better:

1. It doesn't require an XML document header either.
2. Has clearer exceptions
3. Adds extra behaviour options: OmitXmlDeclaration = true, NewLineOnAttributes = true

4. Less lines of code

   static string PrettyXml(string xml)
   {
       var stringBuilder = new StringBuilder();
   
       var element = XElement.Parse(xml);
   
       var settings = new XmlWriterSettings();
       settings.OmitXmlDeclaration = true;
       settings.Indent = true;
       settings.NewLineOnAttributes = true;
   
       using (var xmlWriter = XmlWriter.Create(stringBuilder, settings))
       {
           element.Save(xmlWriter);
       }
   
       return stringBuilder.ToString();
   }
   

Be careful that this will create an "alternate reality" for people who have already fetch/pulled/cloned from the remote repository. But in fact, it's quite simple:

git reset HEAD^ # remove commit locally
git push origin +HEAD # force-push the new HEAD commit

If you want to still have it in your local repository and only remove it from the remote, then you can use:

git push origin +HEAD^:<name of your branch, most likely 'master'>

If you think of the body of a loop as a subroutine, continue is sort of like return. The same keyword exists in C, and serves the same purpose. Here's a contrived example:

for(int i=0; i < 10; ++i) {
  if (i % 2 == 0) {
    continue;
  }
  System.out.println(i);
}

This will print out only the odd numbers.

The solution which worked for me was to add the directive in declarations in app.module.ts

This is accomplished in web.config for your webservice. Set the bindingBehavior to <webHttp> and you will see the clean JSON. The extra "[d]" is set by the default behavior which you need to overwrite.

See in addition this blogpost: http://blog.clauskonrad.net/2010/11/how-to-expose-json-endpoint-from-wcf.html

Gift.new.attributes.symbolize_keys

Not particularly easily- if you've lost the pointer to the tip of a branch, it's rather like finding a needle in a haystack. You can find all the commits that don't appear to be referenced any more- git fsck --unreachable will do this for you- but that will include commits that you threw away after a git commit --amend, old commits on branches that you rebased etc etc. So seeing all these commits at once is quite likely far too much information to wade through.

So the flippant answer is, don't lose track of things you're interested in. More seriously, the reflogs will hold references to all the commits you've used for the last 60 days or so by default. More importantly, they will give some context about what those commits are.

foreach (DataTable table in ds.Tables)
{
    foreach (DataRow dr in table.Rows)
    {
        var ParentId=dr["ParentId"].ToString();
    }
}

Maybe not the most efficient way. But you could convert the list into a vector.

#include <list>
#include <vector>

list<Object> myList;

vector<Object> myVector(myList.begin(), myList.end());

Then access the vector using the [x] operator.

auto x = MyVector[0];

You could put that in a helper function:

#include <memory>
#include <vector>
#include <list>

template<class T>
shared_ptr<vector<T>> 
ListToVector(list<T> List) {
shared_ptr<vector<T>> Vector {
        new vector<string>(List.begin(), List.end()) }
return Vector;
}

Then use the helper funciton like this:

auto MyVector = ListToVector(Object);
auto x = MyVector[0];

simple add(new JScrollPane(textArea), BorderLayout.CENTER);

You can use findHandlersJS

You can find the handler by doing in the chrome console:

findEventHandlers("click", "img.envio")

You'll get the following information printed in chrome's console:

• element
  The actual element where the event handler was registered in
• events
  Array with information about the jquery event handlers for the event type that we are interested in (e.g. click, change, etc)
• handler
  Actual event handler method that you can see by right clicking it and selecting Show function definition
• selector
  The selector provided for delegated events. It will be empty for direct events.
• targets
  List with the elements that this event handler targets. For example, for a delegated event handler that is registered in the document object and targets all buttons in a page, this property will list all buttons in the page. You can hover them and see them highlighted in chrome.

More info here and you can try it in this example site here.

You can't have two elements with the same ID.

Aside from that, you are defining them as block elemnts, meaning (in layman's terms) that they are being forced to appear on their own line.

Instead, try something like this:

<div class="link"><a href="..."><img src="..."... /></a></div>
<div class="link"><a href="..."><img src="..."... /></a></div>

CSS:

.link {
    width: 50%;
    float: left;
    text-align: center;
}

This is how I got sort to work in mongoose 2.3.0 :)

// Find First 10 News Items
News.find({
    deal_id:deal._id // Search Filters
},
['type','date_added'], // Columns to Return
{
    skip:0, // Starting Row
    limit:10, // Ending Row
    sort:{
        date_added: -1 //Sort by Date Added DESC
    }
},
function(err,allNews){
    socket.emit('news-load', allNews); // Do something with the array of 10 objects
})

Here is a better way for doing it. Hope this helps

I had the same issue when switching from a dev branch to master branch. What I did was commit my changes and switch to the master branch. You might have uncommitted changes.

db.data.update({'name': 'zero'}, {'$set': {'value': NumberInt(0)}})

You can also use NumberLong.

What you're trying to achieve is a bit undefined.
What if two or more items in c share the same p? Which item will be mapped to that p in the map?

The more accurate way of looking at this is yielding a map between p and all c items that have it:

val m: Map[P, Collection[T]]

This could be easily achieved with groupBy:

val m: Map[P, Collection[T]] = c.groupBy(t => t.p)

If you still want the original map, you can, for instance, map p to the first t that has it:

val m: Map[P, T] = c.groupBy(t => t.p) map { case (p, ts) =>  p -> ts.head }

I had the same problem.
The proper way would be setting the 'searchText' to be a property inside an object.

But what if I want to leave it as it is, a string? well, I tried every single method mentioned here, nothing worked.
But then I noticed that the problem is only in the initiation, so I've just set the value attribute and it worked.

<input type="text" ng-model="searchText" value={{searchText}} />

This way the value is just set to '$scope.searchText' value and it's being updated when the input value changes.

I know it's a workaround, but it worked for me..

Here is a complete test case that simulates the click event, calls all handlers attached (however they have been attached), maintains the "target" attribute ("srcElement" in IE), bubbles like a normal event would, and emulates IE's recursion-prevention. Tested in FF 2, Chrome 2.0, Opera 9.10 and of course IE (6):

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<script>
function fakeClick(event, anchorObj) {
  if (anchorObj.click) {
    anchorObj.click()
  } else if(document.createEvent) {
    if(event.target !== anchorObj) {
      var evt = document.createEvent("MouseEvents"); 
      evt.initMouseEvent("click", true, true, window, 
          0, 0, 0, 0, 0, false, false, false, false, 0, null); 
      var allowDefault = anchorObj.dispatchEvent(evt);
      // you can check allowDefault for false to see if
      // any handler called evt.preventDefault().
      // Firefox will *not* redirect to anchorObj.href
      // for you. However every other browser will.
    }
  }
}
</script>
</head>
<body>

<div onclick="alert('Container clicked')">
  <a id="link" href="#" onclick="alert((event.target || event.srcElement).innerHTML)">Normal link</a>
</div>

<button type="button" onclick="fakeClick(event, document.getElementById('link'))">
  Fake Click on Normal Link
</button>

<br /><br />

<div onclick="alert('Container clicked')">
    <div onclick="fakeClick(event, this.getElementsByTagName('a')[0])"><a id="link2" href="#" onclick="alert('foo')">Embedded Link</a></div>
</div>

<button type="button" onclick="fakeClick(event, document.getElementById('link2'))">Fake Click on Embedded Link</button>

</body>
</html>

Demo here.

It avoids recursion in non-IE browsers by inspecting the event object that is initiating the simulated click, by inspecting the target attribute of the event (which remains unchanged during propagation).

Obviously IE does this internally holding a reference to its global event object. DOM level 2 defines no such global variable, so for that reason the simulator must pass in its local copy of event.

I was facing with this problem some time ago and I found java.util.LinkedList is best for my case. It has several methods, with different namings, but they're doing what is needed:

push()    -> LinkedList.addLast(); // Or just LinkedList.add();
pop()     -> LinkedList.pollLast();
shift()   -> LinkedList.pollFirst();
unshift() -> LinkedList.addFirst();

By design, Django templates cannot call into arbitrary Python code. This is a security and safety feature for environments where designers write templates, and it also prevents business logic migrating into templates.

If you want to do this, you can switch to using Jinja2 templates (http://jinja.pocoo.org/docs/), or any other templating system you like that supports this. No other part of django will be affected by the templates you use, because it is intentionally a one-way process. You could even use many different template systems in the same project if you wanted.

$image = imagecreatefromjpeg($_GET['src']);

Needs to be replaced with this:

$image = imagecreatefromjpeg('images/thumbnails/myimage.jpg');

Because imagecreatefromjpeg() is expecting a string.
This worked for me.

I think Candy's answer is mostly correct. There is one small part I think otherwise.

To map host:port/context/hello.jsp

1. No exact URL servlets installed, next.
2. Found wildcard paths servlets, return.

I believe that why "/*" does not match host:port/context/hello because it treats "/hello" as a path instead of a file (since it does not have an extension).

This worked for me

#Mount as ReadOnly

su -c "mount -o rw,remount /system"
# Change Permission for file
su -c "chmod 777 /system/build.prop" 
#Edit the file to add the property
su -c "busybox vi /system/build.prop"
# Add now
service.adb.tcp.port=5678

# Reset old permissions
su -c "chmod 644 /system/build.prop"

# Mount as readonly again once done
su -c "mount -o ro,remount /system"

That name looks derived from an object URL GUID. Do the following to get the object URL that the name was derived from.

var URL = self.URL || self.webkitURL || self;
var object_url = URL.createObjectURL(blob);
URL.revokeObjectURL(object_url);

object_url will be formatted as blob:{origin}{GUID} in Google Chrome and moz-filedata:{GUID} in Firefox. An origin is the protocol+host+non-standard port for the protocol. For example, blob:http://stackoverflow.com/e7bc644d-d174-4d5e-b85d-beeb89c17743 or blob:http://[::1]:123/15111656-e46c-411d-a697-a09d23ec9a99. You probably want to extract the GUID and strip any dashes.

You would need to always consider the state of all checkboxes!

You could increase or decrease a number on checking or unchecking, but imagine the site loads with three of them checked.

So you always need to check all of them:

<script type="text/javascript">
<!--
function showMe (it, box) {
  // consider all checkboxes with same name
  var checked = amountChecked(box.name);

  var vis = (checked >= 3) ? "block" : "none";
  document.getElementById(it).style.display = vis;
}

function amountChecked(name) {
  var all = document.getElementsByName(name);

  // count checked
  var result = 0;
  all.forEach(function(el) {
    if (el.checked) result++;
  });

  return result;
}
//-->
</script>

def bubble_sort(l):
    for i in range(len(l) -1):
        for j in range(len(l)-i-1):
            if l[j] > l[j+1]:
                l[j],l[j+1] = l[j+1], l[j]
    return l

If some of your services are balking into ulimits, it's sometimes easier to put appropriate commands into service's init-script. For example, when Apache is reporting

[alert] (11)Resource temporarily unavailable: apr_thread_create: unable to create worker thread

Try to put ulimit -s unlimited into /etc/init.d/httpd. This does not require a server reboot.

class BooleanTester
{
    boolean primitive;
    Boolean object;

    public static void main(String[] args) {
        BooleanTester booleanTester = new BooleanTester();
        System.out.println("primitive: " + booleanTester.getPrimitive());
        System.out.println("object: " + booleanTester.getObject());
}

    public boolean getPrimitive() {
        return primitive;
    }

    public Boolean getObject() {
        return object;
    }
}

output:

primitive: false
object: null

This seems obvious but I had a situation where Jackson, while serializing an object to JSON, was throwing an NPE after calling a getter, just like this one, that returns a primitive boolean which was not assigned. This led me to believe that Jackson was receiving a null and trying to call a method on it, hence the NPE. I was wrong.

Moral of the story is that when Java allocates memory for a primitive, that memory has a value even if not initialized, which Java equates to false for a boolean. By contrast, when allocating memory for an uninitialized complex object like a Boolean, it allocates only space for a reference to that object, not the object itself - there is no object in memory to refer to - so resolving that reference results in null.

I think that strictly speaking, "defaults to false" is a little off the mark. I think Java does not allocate the memory and assign it a value of false until it is explicitly set; I think Java allocates the memory and whatever value that memory happens to have is the same as the value of 'false'. But for practical purpose they are the same thing.

This stores 5 alphanumeric characters in variable c.

for(var c = ''; c.length < 5;) c += Math.random().toString(36).substr(2, 1)

A different perspective to the same problem away from Javascript and using php:

<a data-toggle="modal" href="#myModal">LINK</a>

<div class="modal fade" tabindex="-1" aria-labelledby="gridSystemModalLabel" id="myModal" role="dialog" style="max-width: 90%;">
    <div class="modal-dialog" style="text-align: left;">
        <div class="modal-content">
            <div class="modal-header">
                <button type="button" class="close" data-dismiss="modal">&times;</button>
                <h4 class="modal-title">Title</h4>
            </div>
            <div class="modal-body">
                <?php include( 'remotefile.php'); ?>
            </div>
            <div class="modal-footer">
                <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
            </div>
        </div>
    </div>
</div>

and put in the remote.php file your basic html source.

Python:

python -c "from datetime import datetime; print(datetime.fromtimestamp($TIMESTAMP))"

After you correct the possible dmp file problem, this is a way to ensure that the schema is remapped and imported appropriately. This will also ensure that the tablespace will change also, if needed:

impdp system/<password> SCHEMAS=user1 remap_schema=user1:user2 \
            remap_tablespace=user1:user2 directory=EXPORTDIR \
            dumpfile=user1.dmp logfile=E:\Data\user1.log

EXPORTDIR must be defined in oracle as a directory as the system user

create or replace directory EXPORTDIR as 'E:\Data';
grant read, write on directory EXPORTDIR to user2;

I had an instance where I wanted to update the model of a sumitted form, and did not want to 'Redirect To Action' for performanace reason. Previous values of hidden fields were being retained on my updated model - causing allsorts of issues!.

A few lines of code soon identified the elements within ModelState that I wanted to remove (after validation), so the new values were used in the form:-

while (ModelState.FirstOrDefault(ms => ms.Key.ToString().StartsWith("SearchResult")).Value != null)
{
    ModelState.Remove(ModelState.FirstOrDefault(ms => ms.Key.ToString().StartsWith("SearchResult")));
}
