You can seek until the end, then compute the difference:

std::streampos fileSize( const char* filePath ){

    std::streampos fsize = 0;
    std::ifstream file( filePath, std::ios::binary );

    fsize = file.tellg();
    file.seekg( 0, std::ios::end );
    fsize = file.tellg() - fsize;
    file.close();

    return fsize;
}

If you are using the Git Bash shell, you can use the following trick:

> webpage.html

This is actually the same as:

echo "" > webpage.html

Then, you can use git add webpage.html to stage the file.

React behavior

Apart from the rest of the answers, I would like to show one difference in React.

If I throw a new Error() and I am in development mode, I will get an error screen and a console log. If I throw a string literal, I will only see it in the console and possibly miss it, if I am not watching the console log.

Example

Throwing an error logs into the console and shows an error screen while in development mode (the screen won't be visible in production).

throw new Error("The application could not authenticate.");

Whereas the following code only logs into the console:

throw "The application could not authenticate.";

Use dt.days to obtain the days attribute as integers.

For eg:

In [14]: s = pd.Series(pd.timedelta_range(start='1 days', end='12 days', freq='3000T'))

In [15]: s
Out[15]: 
0    1 days 00:00:00
1    3 days 02:00:00
2    5 days 04:00:00
3    7 days 06:00:00
4    9 days 08:00:00
5   11 days 10:00:00
dtype: timedelta64[ns]

In [16]: s.dt.days
Out[16]: 
0     1
1     3
2     5
3     7
4     9
5    11
dtype: int64

More generally - You can use the .components property to access a reduced form of timedelta.

In [17]: s.dt.components
Out[17]: 
   days  hours  minutes  seconds  milliseconds  microseconds  nanoseconds
0     1      0        0        0             0             0            0
1     3      2        0        0             0             0            0

Now, to get the hours attribute:

Here is part of a line in my code that brought the warning up in NetBeans:

$page = (!empty($_GET['p'])) 

After much research and seeing how there are about a bazillion ways to filter this array, I found one that was simple. And my code works and NetBeans is happy:

$p = filter_input(INPUT_GET, 'p');
$page = (!empty($p))

Here you go: http://mochajs.org/#test-level

it('accesses the network', function(done){
  this.timeout(500);
  [Put network code here, with done() in the callback]
})

For arrow function use as follows:

it('accesses the network', (done) => {
  [Put network code here, with done() in the callback]
}).timeout(500);

You can do the following if you already know the number of fields of the input:

client_name = raw_input("Enter you first and last name: ")
first_name, last_name = client_name.split() 

and in case you want to iterate through the fields separated by spaces, you can do the following:

some_input = raw_input() # This input is the value separated by spaces
for field in some_input.split():
    print field # this print can be replaced with any operation you'd like
    #             to perform on the fields.

A more generic use of the "split()" function would be:

    result_list = some_string.split(DELIMITER)

where DELIMETER is replaced with the delimiter you'd like to use as your separator, with single quotes surrounding it.

An example would be:

    result_string = some_string.split('!')    

The code above takes a string and separates the fields using the '!' character as a delimiter.

"Pack" and POST your data against the "context" that universe-resource-locator provides, which means #1 for the sake of the locator.

Mind the limitations with #2. I prefer POSTs to #1.

note: limitations are discussed for

POST in Is there a max size for POST parameter content?

GET in Is there a limit to the length of a GET request? and Max size of URL parameters in _GET

p.s. these limits are based on the client capabilities (browser) and server(configuration).

using LINQ and Lamba, i wanted to return two field values and assign it to single entity object field;

as Name = Fname + " " + LName;

See my below code which is working as expected; hope this is useful;

Myentity objMyEntity = new Myentity
{
id = obj.Id,
Name = contxt.Vendors.Where(v => v.PQS_ID == obj.Id).Select(v=> new { contact = v.Fname + " " + v.LName}).Single().contact
}

no need to declare the 'contact'

The last inserted record can be queried using this assuming you have the "id" as the primary key:

SELECT timestamp,value,card FROM my_table WHERE id=(select max(id) from my_table)

Assuming every new row inserted will use the highest integer value for the table's id.

I also had the same problem. My maven had tomcat7 plugin but the JRE environment was 1.6. I changed my tomcat7 to tomcat6 and the error was gone.

For Swift 3,

let index = array.index(where: {$0.name == "foo"})

I use image instead of background-image when i want to make them 100% stretchable which supported in most browsers.

Node : http://www.w3schools.com/js/js_htmldom_nodes.asp

The Node object represents a single node in the document tree. A node can be an element node, an attribute node, a text node, or any other of the node types explained in the Node Types chapter.

Element : http://www.w3schools.com/js/js_htmldom_elements.asp

The Element object represents an element in an XML document. Elements may contain attributes, other elements, or text. If an element contains text, the text is represented in a text-node.

I had that problem while using IntelliJ (14.1.3 Ultimate), I wanted to revert changes in some file.

Solved by closing Git Bash opened in another window - another revert trial in IntelliJ worked.

I agree with the current answers, but in my case it does not work, I hope this code help someone in the future:

// check
$('#checkbox_id').click()

for me it was installed in /usr/local/opt

The command I used for installation is brew install [email protected]

Last-Modified : The last modified date for the requested object

If-Modified-Since : Allows a 304 Not Modified to be returned if last modified date is unchanged.

ETag : An ETag is an opaque identifier assigned by a web server to a specific version of a resource found at a URL. If the resource representation at that URL ever changes, a new and different ETag is assigned.

If-None-Match : Allows a 304 Not Modified to be returned if ETag is unchanged.

the browser store cache with a date(Last-Modified) or id(ETag), when you need to request the URL again, the browser send request message with the header:

the server will return 304 when the if statement is False, and browser will use cache.

I was stuck with ast.literal_eval(). I was trying it in IntelliJ IDEA debugger, and it kept returning None on debugger output.

But later when I assigned its output to a variable and printed it in code. It worked fine. Sharing code example:

import ast
sample_string = '[{"id":"XYZ_GTTC_TYR", "name":"Suction"}]'
output_value = ast.literal_eval(sample_string)
print(output_value)

Its python version 3.6.

I use this. Ripple effect and button click shadow working.

The well-established "pattern" for reverse-iterating through closed-open ranges looks as follows

// Iterate over [begin, end) range in reverse
for (iterator = end; iterator-- != begin; ) {
  // Process `*iterator`
}

or, if you prefer,

// Iterate over [begin, end) range in reverse
for (iterator = end; iterator != begin; ) {
  --iterator;
  // Process `*iterator`
}

This pattern is useful, for example, for reverse-indexing an array using an unsigned index

int array[N];
...
// Iterate over [0, N) range in reverse
for (unsigned i = N; i-- != 0; ) {
  array[i]; // <- process it
}

(People unfamiliar with this pattern often insist on using signed integer types for array indexing specifically because they incorrectly believe that unsigned types are somehow "unusable" for reverse indexing)

It can be used for iterating over an array using a "sliding pointer" technique

// Iterate over [array, array + N) range in reverse
for (int *p = array + N; p-- != array; ) {
  *p; // <- process it
}

or it can be used for reverse-iteration over a vector using an ordinary (not reverse) iterator

for (vector<my_class>::iterator i = my_vector.end(); i-- != my_vector.begin(); ) {
  *i; // <- process it
}

The first solution does not work for any UTF-8 alphabet. (It will cut text such as ????). I have managed to create a function which does not use RegExp and use good UTF-8 support in the JavaScript engine. The idea is simple if a symbol is equal in uppercase and lowercase it is a special character. The only exception is made for whitespace.

function removeSpecials(str) {
    var lower = str.toLowerCase();
    var upper = str.toUpperCase();

    var res = "";
    for(var i=0; i<lower.length; ++i) {
        if(lower[i] != upper[i] || lower[i].trim() === '')
            res += str[i];
    }
    return res;
}

Update: Please note, that this solution works only for languages where there are small and capital letters. In languages like Chinese, this won't work.

Update 2: I came to the original solution when I was working on a fuzzy search. If you also trying to remove special characters to implement search functionality, there is a better approach. Use any transliteration library which will produce you string only from Latin characters and then the simple Regexp will do all magic of removing special characters. (This will work for Chinese also and you also will receive side benefits by making Tromsø == Tromso).

Basically, The reason behind these type of error is eventually you are trying to delete a tupple which has primary key (root table) & that primary key is used in child table as a foreign key. In this scenario in order to delete parent table data you have to remove child table data (in which foreign key is used). Thanks

Many frameworks like Laravel , Django ,... run local web server that work on another port except 80.For example port 8000 is the most commen port that these local web servers use.

So when you run web servers that frameworks build them and type localhost:8000 it works well.But web server that xampp(apache) runs it has another port.In default it has 80 that it does not need to type it in url.And if you change port you should mention it in url.

**In brief:**web server in framework is different from web server in xampp . Check the port of each server and mention it in url when you use them.

More easy and beautiful if you has vue.js v-money-spinner :)

First off - check with Firebug(or what ever your preference is) whether the css property is being interpreted by the browser. Sometimes the tool used will give you the problem right there, so no more hunting.

Second off - check compatibility: http://caniuse.com/#feat=calc

And third - I ran into some problems a few hours ago and just resolved it. It's the smallest thing but it kept me busy for 30 minutes.

Here's how my CSS looked

#someElement {
    height:calc(100%-100px);
    height:-moz-calc(100%-100px);
    height:-webkit-calc(100%-100px);
}

Looks right doesn't it? WRONG Here's how it should look:

#someElement {
    height:calc(100% - 100px);
    height:-moz-calc(100% - 100px);
    height:-webkit-calc(100% - 100px);
}

Looks the same right?

Notice the spaces!!! Checked android browser, Firefox for android, Chrome for android, Chrome and Firefox for Windows and Internet Explorer 11. All of them ignored the CSS if there were no spaces.

Hope this helps someone.

From stack trace:

HikariPool: Timeout failure pool HikariPool-0 stats (total=20, active=20, idle=0, waiting=0) Means pool reached maximum connections limit set in configuration.

The next line: HikariPool-0 - Connection is not available, request timed out after 30000ms. Means pool waited 30000ms for free connection but your application not returned any connection meanwhile.

Mostly it is connection leak (connection is not closed after borrowing from pool), set leakDetectionThreshold to the maximum value that you expect SQL query would take to execute.

otherwise, your maximum connections 'at a time' requirement is higher than 20 !

SOLUTION ONE

$this->db->where('id', '3');
// here we select every column of the table
$q = $this->db->get('my_users_table');
$data = $q->result_array();

echo($data[0]['age']);

SOLUTION TWO

// here we select just the age column
$this->db->select('age');
$this->db->where('id', '3');
$q = $this->db->get('my_users_table');
$data = $q->result_array();

echo($data[0]['age']);

SOLUTION THREE

$this->db->select('age');
$this->db->where('id', '3');
$q = $this->db->get('my_users_table');
// if id is unique, we want to return just one row
$data = array_shift($q->result_array());

echo($data['age']);

SOLUTION FOUR (NO ACTIVE RECORD)

$q = $this->db->query('SELECT age FROM my_users_table WHERE id = ?',array(3));
$data = array_shift($q->result_array());
echo($data['age']);

Looks like the setup.py uses easy_install (i.e. setuptools). Just install the setuptools package and you will be all set.

To install setuptools in Python 2.6, see the answer to this question.

Use a scalar-valued UDF, not a table-value one, then you can use it in a SELECT as you want.

A simple working code to download a file with SSH.NET library is:

using (Stream fileStream = File.Create(@"C:\target\local\path\file.zip"))
{
    sftp.DownloadFile("/source/remote/path/file.zip", fileStream);
}

See also Downloading a directory using SSH.NET SFTP in C#.

To explain, why your code does not work:

The second parameter of SftpClient.DownloadFile is a stream to write a downloaded contents to.

You are passing in a read stream instead of a write stream. And moreover the path you are opening read stream with is a remote path, what cannot work with File class operating on local files only.

Just discard the File.OpenRead line and use a result of previous File.OpenWrite call instead (that you are not using at all now):

Stream file1 = File.OpenWrite(localFileName);

sftp.DownloadFile(file.FullName, file1);

Or even better, use File.Create to discard any previous contents that the local file may have.

I'm not sure if your localFileName is supposed to hold full path, or just file name. So you may need to add a path too, if necessary (combine localFileName with sDir?)

What also is being said in the comments, SQLite sees your input as 1, 25, 62, 7. I also had a problem with , and in my case it was solved by changing "separator ," into ".mode csv". So you could try:

sqlite> create table foo(a, b);
sqlite> .mode csv
sqlite> .import test.csv foo

The first command creates the column names for the table. However, if you want the column names inherited from the csv file, you might just ignore the first line.

Arrays in Java have a defined size, you cannot change it later by adding or removing elements (you can read some basics here).

Instead, use a List:

ArrayList<String> mylist = new ArrayList<String>();
mylist.add(mystring); //this adds an element to the list.

Of course, if you know beforehand how many strings you are going to put in your array, you can create an array of that size and set the elements by using the correct position:

String[] myarray = new String[numberofstrings];
myarray[23] = string24; //this sets the 24'th (first index is 0) element to string24.

One more thing to watch out for is if the second value was another Integer object instead of a literal '0', the '==' operator compares the object pointers and will not auto-unbox.

ie:

Integer a = new Integer(0);   
Integer b = new Integer(0);   
int c = 0;

boolean isSame_EqOperator = (a==b); //false!
boolean isSame_EqMethod = (a.equals(b)); //true
boolean isSame_EqAutoUnbox = ((a==c) && (a.equals(c)); //also true, because of auto-unbox

//Note: for initializing a and b, the Integer constructor 
// is called explicitly to avoid integer object caching 
// for the purpose of the example.
// Calling it explicitly ensures each integer is created 
// as a separate object as intended.
// Edited in response to comment by @nolith

This is another way to specify the range of the bit-vector.

x +: N, The start position of the vector is given by x and you count up from x by N.

There is also

x -: N, in this case the start position is x and you count down from x by N.

N is a constant and x is an expression that can contain iterators.

It has a couple of benefits -

1. It makes the code more readable.

2. You can specify an iterator when referencing bit-slices without getting a "cannot have a non-constant value" error.

None of the existing answers here has provided a complete example of how to do this from within a script (not a one-liner). Here is what I did:

rename($file, $file.'.bak');
open(IN, '<'.$file.'.bak') or die $!;
open(OUT, '>'.$file) or die $!;
while(<IN>)
{
    $_ =~ s/blue/red/g;
    print OUT $_;
}
close(IN);
close(OUT);

Insert a column, for instance a new A column. Then use this function;

="k"&B1

and copy it down.

Then you can hide the new column A if you need too.

The solution only solves part of the problem, it may let you style the container and contents but doesn't let you change the titlebar. I developed a workaround of sorts but adding an id to the dialog div, then using jQuery .prev to change the style of the div which is the previous sibling of the dialog's div. This works because when jQueryUI creates the dialog, your original div becomes a sibling of the new container, but the title div is a the immediately previous sibling to your original div but neither the container not the title div has an id to simplify selecting the div.

HTML

<button id="dialog1" class="btn btn-danger">Warning</button>
<div title="Nothing here, really" id="nonmodal1">
  Nothing here
</div>

You can use CSS to style the main section of the dialog but not the title

.custom-ui-widget-header-warning {
  background: #EBCCCC;
  font-size: 1em;
}

You need some JS to style the title

$(function() {
                   $("#nonmodal1").dialog({
                     minWidth: 400,
                     minHeight: 'auto',
                     autoOpen: false,
                     dialogClass: 'custom-ui-widget-header-warning',
                     position: {
                       my: 'center',
                       at: 'left'
                     }
                   });

                   $("#dialog1").click(function() {
                     if ($("#nonmodal1").dialog("isOpen") === true) {
                       $("#nonmodal1").dialog("close");
                     } else {
                       $("#nonmodal1").dialog("open").prev().css('background','#D9534F');

                     }
                   });
    });

The example only shows simple styling (background) but you can make it as complex as you wish.

You can see it in action here:

Adding an answer that exclusively uses the pandas library to read in a .csv file and save as a .xlsx file. This example makes use of pandas.read_csv (Link to docs) and pandas.dataframe.to_excel (Link to docs).

The fully reproducible example uses numpy to generate random numbers only, and this can be removed if you would like to use your own .csv file.

import pandas as pd
import numpy as np

# Creating a dataframe and saving as test.csv in current directory
df = pd.DataFrame(np.random.randn(100000, 3), columns=list('ABC'))
df.to_csv('test.csv', index = False)

# Reading in test.csv and saving as test.xlsx

df_new = pd.read_csv('test.csv')
writer = pd.ExcelWriter('test.xlsx')
df_new.to_excel(writer, index = False)
writer.save()

In fact the answer of Brain Mains is almost correct:

@Html.TextBoxFor(model => model.RIF, new { value = @Model.RIF, @readonly = true })

To insert a new row into a given table (tblTable) :

INSERT INTO tblTable (DateColumn) VALUES (GETDATE())

To update an existing row :

UPDATE tblTable SET DateColumn = GETDATE()
 WHERE ID = RequiredUpdateID

Note that when INSERTing a new row you will need to observe any constraints which are on the table - most likely the NOT NULL constraint - so you may need to provide values for other columns eg...

 INSERT INTO tblTable (Name, Type, DateColumn) VALUES ('John', 7, GETDATE())

In my Windows machine, I tried the solution of @nzrytmn i.e., Control Panel>Search Credentials>Select "ManageCredentials">modified new credentials under git option category corresponding to my username. And then,

Deleted current password:

git config --global --unset user.password

Added new password:

git config --global --add user.password "new_password"

And It worked for me.

What do you consider "special" characters, just simple punctuation? You should be able to use the Replace function: Replace("p.k","."," ").

Sub Test()
Dim myString as String
Dim newString as String

myString = "p.k"

newString = replace(myString, ".", " ")

MsgBox newString

End Sub

If you have several characters, you can do this in a custom function or a simple chained series of Replace functions, etc.

  Sub Test()
Dim myString as String
Dim newString as String

myString = "!p.k"

newString = Replace(Replace(myString, ".", " "), "!", " ")

'## OR, if it is easier for you to interpret, you can do two sequential statements:
'newString = replace(myString, ".", " ")
'newString = replace(newString, "!", " ")

MsgBox newString

End Sub

If you have a lot of potential special characters (non-English accented ascii for example?) you can do a custom function or iteration over an array.

Const SpecialCharacters As String = "!,@,#,$,%,^,&,*,(,),{,[,],},?"  'modify as needed
Sub test()
Dim myString as String
Dim newString as String
Dim char as Variant
myString = "!p#*@)k{kdfhouef3829J"
newString = myString
For each char in Split(SpecialCharacters, ",")
    newString = Replace(newString, char, " ")
Next
End Sub

Right now, this is the only way

- name: Ensures {{project_root}}/conf dir exists
  file: path={{project_root}}/conf state=directory
- name: Copy file

    dest: "{{project_root}}/conf/code.conf"

With Underscore.js or (even better) Lodash:

_.has(x, 'key');

Which calls Object.prototype.hasOwnProperty, but (a) is shorter to type, and (b) uses "a safe reference to hasOwnProperty" (i.e. it works even if hasOwnProperty is overwritten).

In particular, Lodash defines _.has as:

Short answer: You can't.

Long answer: You could use a modal to display a popup with the image you need.

You can refer to this as an example to a modal.

Thanks for the direction from the above two answerers. James Thompson's suggestion worked best for Windows users.

1. Go to where your R program is installed. This is referred to as R_Home in the literature. Once you find it, go to the /etc subdirectory.

   C:\R\R-2.10.1\etc
   

2. Select the file in this folder named Rprofile.site. I open it with VIM. You will find this is a bare-bones file with less than 20 lines of code. I inserted the following inside the code:

   # my custom library path
   .libPaths("C:/R/library")
   

   (The comment added to keep track of what I did to the file.)

3. In R, typing the .libPaths() function yields the first target at C:/R/Library

NOTE: there is likely more than one way to achieve this, but other methods I tried didn't work for some reason.

Right click on project -> Run As -> Run Configurations..-> Select Arguments tab -> In VM Arguments you can increase your JVM memory allocation. Java HotSpot document will help you to setup your VM Argument HERE

I will not prefer to make any changes into eclipse.ini as minor mistake cause lot of issues. It's easier to play with VM Args

Try this one.

function showFileSize() {_x000D_
  let file = document.getElementById("file").files[0];_x000D_
  if(file) {_x000D_
    alert(file.size + " in bytes"); _x000D_
  } else { _x000D_
    alert("select a file... duh"); _x000D_
  }_x000D_
}

<input type="file" id="file"/>_x000D_
<button onclick="showFileSize()">show file size</button>

It depends on the parameter type. For example, I just discovered today that it will convert a char directly to int using its ASCII value. Not exactly the functionality I intended...

YOU HAVE BEEN WARNED!

public static int ToInt32(char value)
{
    return (int)value;
} 

Convert.ToInt32('1'); // Returns 49
int.Parse('1'); // Returns 1

The solution by PeterVR has the disadvantage that the additional color displays on top of the entire HTML block - meaning that it also shows up on top of div content, not just on top of the background image. This is fine if your div is empty, but if it is not using a linear gradient might be a better solution:

<div class="the-div">Red text</div>

<style type="text/css">
  .the-div
  {
    background-image: url("the-image.png");
    color: #f00;
    margin: 10px;
    width: 200px;
    height: 80px;
  }
  .the-div:hover
  {
    background-image: linear-gradient(to bottom, rgba(0, 0, 0, 0.1), rgba(0, 0, 0, 0.1)), url("the-image.png");
    background-image: -moz-linear-gradient(top, rgba(0, 0, 0, 0.1), rgba(0, 0, 0, 0.1)), url("the-image.png");
    background-image: -o-linear-gradient(top, rgba(0, 0, 0, 0.1), rgba(0, 0, 0, 0.1)), url("the-image.png");
    background-image: -ms-linear-gradient(top, rgba(0, 0, 0, 0.1), rgba(0, 0, 0, 0.1)), url("the-image.png");
    background-image: -webkit-gradient(linear, left top, left bottom, from(rgba(0, 0, 0, 0.1)), to(rgba(0, 0, 0, 0.1))), url("the-image.png");
    background-image: -webkit-linear-gradient(top, rgba(0, 0, 0, 0.1), rgba(0, 0, 0, 0.1)), url("the-image.png");
  }
</style>

See fiddle. Too bad that gradient specifications are currently a mess. See compatibility table, the code above should work in any browser with a noteworthy market share - with the exception of MSIE 9.0 and older.

Edit (March 2017): The state of the web got far less messy by now. So the linear-gradient (supported by Firefox and Internet Explorer) and -webkit-linear-gradient (supported by Chrome, Opera and Safari) lines are sufficient, additional prefixed versions are no longer necessary.

Assuming that MemoryStream name is ms.

This code writes down MemoryStream to a file:

using (FileStream file = new FileStream("file.bin", FileMode.Create, System.IO.FileAccess.Write)) {
   byte[] bytes = new byte[ms.Length];
   ms.Read(bytes, 0, (int)ms.Length);
   file.Write(bytes, 0, bytes.Length);
   ms.Close();
}

and this reads a file to a MemoryStream :

using (MemoryStream ms = new MemoryStream())
using (FileStream file = new FileStream("file.bin", FileMode.Open, FileAccess.Read)) {
   byte[] bytes = new byte[file.Length];
   file.Read(bytes, 0, (int)file.Length);
   ms.Write(bytes, 0, (int)file.Length);
}

In .Net Framework 4+, You can simply copy FileStream to MemoryStream and reverse as simple as this:

MemoryStream ms = new MemoryStream();
using (FileStream file = new FileStream("file.bin", FileMode.Open, FileAccess.Read))
    file.CopyTo(ms);

And the Reverse (MemoryStream to FileStream):

using (FileStream file = new FileStream("file.bin", FileMode.Create, System.IO.FileAccess.Write))
    ms.CopyTo(file);

If you do that, you are forcing it to do a string conversion. It would be better to build a start/end date range, and use:

declare @start datetime, @end datetime
select @start = '2009-10-10', @end = '2009-11-10'
select * from record where register_date >= @start
           and register_date < @end

This will allow it to use the index (if there is one on register_date), rather than a table scan.

You likely need to re-start VNC on both ends. i.e. when you say "restarted VNC", you probably just mean the client. But what about the other end? You likely need to re-start that end too. The root cause is likely a conflict. Many apps spy on the clipboard when they shouldn't. And many apps are not forgiving when they go to open the clipboard and can't. Robust ones will retry, others will simply not anticipate a failure and then they get fouled up and need to be restarted. Could be VNC, or it could be another app that's "listening" to the clipboard viewer chain, where it is obligated to pass along notifications to the other apps in the chain. If the notifications aren't sent, then VNC may not even know that there has been a clipboard update.

I had similar message and after several searches online and doing all suggestions, nothing helped. Finally I found the solution. In my IIS server, under the application pool advance option, there is an option for "Enable 32-Bit Applications" - that was changed from false to true and after restarting IIS server, My program started generating pdf files.

In my opinion, the easiest way to do is adding padding to your tag.

td {
 padding: 10px 0
}

Hope this will help you! Cheer!

You can solve the problem changing the compileSdkVersion in the Grandle.build file from 18 to wtever SDK is installed ..... BUTTTTT

1. If you are trying to goin back in SDK versions like 18 to 17 ,You can not use the feature available in 18 or 18+

2. If you are migrating your project (Eclipse to Android Studio ) Then off course you Don't have build.gradle file in your Existed Eclipse project

So, the only solution is to ensure the SDK version installed or not, you are targeting to , If not then install.

Error:Cause: failed to find target with hash string 'android-19' in: C:\Users\setia\AppData\Local\Android\sdk

You will have to open the file in one way or another if you want to access the data within it. Obviously, one way is to open it in your Excel application instance, e.g.:-

(untested code)

Dim wbk As Workbook
Set wbk = Workbooks.Open("C:\myworkbook.xls")

' now you can manipulate the data in the workbook anyway you want, e.g. '

Dim x As Variant
x = wbk.Worksheets("Sheet1").Range("A6").Value

Call wbk.Worksheets("Sheet2").Range("A1:G100").Copy
Call ThisWorbook.Worksheets("Target").Range("A1").PasteSpecial(xlPasteValues)
Application.CutCopyMode = False

' etc '

Call wbk.Close(False)

Another way to do it would be to use the Excel ADODB provider to open a connection to the file and then use SQL to select data from the sheet you want, but since you are anyway working from within Excel I don't believe there is any reason to do this rather than just open the workbook. Note that there are optional parameters for the Workbooks.Open() method to open the workbook as read-only, etc.

I can suggest that you both create and initialize your array at the same line using linq:

List<int>[] a = new List<int>[100].Select(item=>new List<int>()).ToArray();

ILookup Interface is used in .net 3.5 with linq.

The HashTable is the base class that is weakly type; the DictionaryBase abstract class is stronly typed and uses internally a HashTable.

I found a a strange thing about Dictionary, when we add the multiple entries in Dictionary, the order in which the entries are added is maintained. Thus if I apply a foreach on the Dictionary, I will get the records in the same order I have inserted them.

Whereas, this is not true with normal HashTable, as when I add same records in Hashtable the order is not maintained. As far as my knowledge goes, Dictionary is based on Hashtable, if this is true, why my Dictionary maintains the order but HashTable does not?

As to why they behave differently, it's because Generic Dictionary implements a hashtable, but is not based on System.Collections.Hashtable. The Generic Dictionary implementation is based on allocating key-value-pairs from a list. These are then indexed with the hashtable buckets for random access, but when it returns an enumerator, it just walks the list in sequential order - which will be the order of insertion as long as entries are not re-used.

UPDATE: for rxjs > v5.5

As mentioned in some of the comments and other answers, by default the HttpClient deserializes the content of a response into an object. Some of its methods allow passing a generic type argument in order to duck-type the result. Thats why there is no json() method anymore.

import {throwError} from 'rxjs';
import {catchError, map} from 'rxjs/operators';

export interface Order {
  // Properties
}

interface ResponseOrders {
  results: Order[];
}

@Injectable()
export class FooService {
 ctor(private http: HttpClient){}

 fetch(startIndex: number, limit: number): Observable<Order[]> {
    let params = new HttpParams();
    params = params.set('startIndex',startIndex.toString()).set('limit',limit.toString());
    // base URL should not have ? in it at the en
    return this.http.get<ResponseOrders >(this.baseUrl,{
       params
    }).pipe(
       map(res => res.results || []),
       catchError(error => _throwError(error.message || error))
    );
} 

Notice that you could easily transform the returned Observable to a Promise by simply invoking toPromise().

ORIGINAL ANSWER:

In your case, you can

Assumming that your backend returns something like:

{results: [{},{}]}

in JSON format, where every {} is a serialized object, you would need the following:

// Somewhere in your src folder

export interface Order {
  // Properties
}

import { HttpClient, HttpParams } from '@angular/common/http';
import { Observable } from 'rxjs/Observable';
import 'rxjs/add/operator/catch';
import 'rxjs/add/operator/map';

import { Order } from 'somewhere_in_src';    

@Injectable()
export class FooService {
 ctor(private http: HttpClient){}

 fetch(startIndex: number, limit: number): Observable<Order[]> {
    let params = new HttpParams();
    params = params.set('startIndex',startIndex.toString()).set('limit',limit.toString());
    // base URL should not have ? in it at the en
    return this.http.get(this.baseUrl,{
       params
    })
    .map(res => res.results as Order[] || []); 
   // in case that the property results in the res POJO doesnt exist (res.results returns null) then return empty array ([])
  }
} 

I removed the catch section, as this could be archived through a HTTP interceptor. Check the docs. As example:

https://gist.github.com/jotatoledo/765c7f6d8a755613cafca97e83313b90

And to consume you just need to call it like:

// In some component for example
this.fooService.fetch(...).subscribe(data => ...); // data is Order[]

For Windows 7: c:\users\all users\MySql\MySql Server x.x\Data\

Where x.x is the version number of the sql server installed in your machine.

The IF/THEN/ELSE construct you are using is only valid in stored procedures and functions. Your query will need to be restructured because you can't use the IF() function to control the flow of the WHERE clause like this.

The IF() function that can be used in queries is primarily meant to be used in the SELECT portion of the query for selecting different data based on certain conditions, not so much to be used in the WHERE portion of the query:

SELECT IF(JQ.COURSE_ID=0, 'Some Result If True', 'Some Result If False'), OTHER_COLUMNS
FROM ...
WHERE ...

If you want all the bars to get the same color (fill), you can easily add it inside geom_bar.

ggplot(data=df, aes(x=c1+c2/2, y=c3)) + 
geom_bar(stat="identity", width=c2, fill = "#FF6666")

Add fill = the_name_of_your_var inside aes to change the colors depending of the variable :

c4 = c("A", "B", "C")
df = cbind(df, c4)
ggplot(data=df, aes(x=c1+c2/2, y=c3, fill = c4)) + 
geom_bar(stat="identity", width=c2)

Use scale_fill_manual() if you want to manually the change of colors.

ggplot(data=df, aes(x=c1+c2/2, y=c3, fill = c4)) + 
geom_bar(stat="identity", width=c2) + 
scale_fill_manual("legend", values = c("A" = "black", "B" = "orange", "C" = "blue"))

Jonathon's excellent solution breaks in IE8 (the animation does not show at all). To fix this, change the CSS to:

.modal {
display:    none;
position:   fixed;
z-index:    1000;
top:        0;
left:       0;
height:     100%;
width:      100%;
background: rgba( 255, 255, 255, .8 ) 
            url('http://i.stack.imgur.com/FhHRx.gif') 
            50% 50% 
            no-repeat;
opacity: 0.80;
-ms-filter: progid:DXImageTransform.Microsoft.Alpha(Opacity = 80);
filter: alpha(opacity = 80)};

(Comment)

I can't comment yet, so posting here... I just tried the above OSK.EXE debug trick but regedit instantly closes when I save the filled "C:\windows\system32\cmd.exe" into the already created Debugger key so Microsoft is actively working to block native ways to do this. It is really weird because other things do not trigger this.

Using task scheduler does create a SYSTEM CMD but it is in the system environment and not displayed within a human user profile so this is also now defunct (though it is logical).

Currently on Microsoft Windows [Version 10.0.20201.1000]

So, at this point it has to be third party software that mediates this and further tricks are being more actively sealed by Microsoft these days.

To perform this operation see the next images:

and next step is add *.mdf file,

very important, the .mdf file must be located in C:......\MSSQL12.SQLEXPRESS\MSSQL\DATA

Now remove the log file

A tree can be called as a binary tree if and only if the maximum number of children of any of the nodes is two.

A tree can be called as a binary search tree if and only if the maximum number of children of any of the nodes is two and the left child is always smaller than the right child.

I arrived here trying to install Appium. Adding my answer in case other folks land here for the same issue.

appium-doctor --ios

... bunch of stuff...

WARN AppiumDoctor ? Error running xcrun simctl

... bunch of stuff...

info AppiumDoctor ### Manual Fixes Needed ###

info AppiumDoctor The configuration cannot be automatically fixed, please do the following first:

WARN AppiumDoctor ? Manually install Xcode, and make sure 'xcode-select -p' command shows proper path like '/Applications/Xcode.app/Contents/Developer'

In my case

xcode-select -p

/Library/Developer/CommandLineTools

which appeared wrong...but I knew I had recently updated Xcode and the command line tools

so...

sudo xcode-select -r (sudo required)

then...

xcode-select -p
/Applications/Xcode.app/Contents/Developer

After this, no warning. Appium-doctor returned clean.

Sometimes you just need to suppress only some warnings and you want to keep other warnings, just to be safe. In your code, you can suppress the warnings for variables and even formal parameters by using GCC's unused attribute. Lets say you have this code snippet:

void func(unsigned number, const int version)
{
  unsigned tmp;
  std::cout << number << std::endl;
}

There might be a situation, when you need to use this function as a handler - which (imho) is quite common in C++ Boost library. Then you need the second formal parameter version, so the function's signature is the same as the template the handler requires, otherwise the compilation would fail. But you don't really need it in the function itself either...

The solution how to mark variable or the formal parameter to be excluded from warnings is this:

void func(unsigned number, const int version __attribute__((unused)))
{
  unsigned tmp __attribute__((unused));
  std::cout << number << std::endl;
}

GCC has many other parameters, you can check them in the man pages. This also works for the C programs, not only C++, and I think it can be used in almost every function, not just handlers. Go ahead and try it! ;)

P.S.: Lately I used this to suppress warnings of Boosts' serialization in template like this:

template <typename Archive>
void serialize(Archive &ar, const unsigned int version __attribute__((unused)))

EDIT: Apparently, I didn't answer your question as you needed, drak0sha done it better. It's because I mainly followed the title of the question, my bad. Hopefully, this might help other people, who get here because of that title... :)

For future reference Python is strongly typed. Unlike other dynamic languages, it will not automagically cast objects from one type or the other (say from str to int) so you must do this yourself. You'll like that in the long-run, trust me!

In this moment with the last version of the C# driver (2.3.0) the only way I found to get the database name specified in connection string is this:

var connectionString = @"mongodb://usr:[email protected],srv2.acme.net,srv3.acme.net/dbName?replicaSet=rset";
var mongoUrl = new MongoUrl(connectionString);
var dbname = mongoUrl.DatabaseName;
var db = new MongoClient(mongoUrl).GetDatabase(dbname);
db.GetCollection<MyType>("myCollectionName");

You can also do the update directly in MongoDB without having to load the document and modify it using code. Use the $pull or $pullAll operators to remove the item from the array :

Favorite.updateOne( {cn: req.params.name}, { $pullAll: {uid: [req.params.deleteUid] } } )

(you can also use updateMany for multiple documents)

http://docs.mongodb.org/manual/reference/operator/update/pullAll/

Jersey's UriBuilder encodes URI components using application/x-www-form-urlencoded and RFC 3986 as needed. According to the Javadoc

Builder methods perform contextual encoding of characters not permitted in the corresponding URI component following the rules of the application/x-www-form-urlencoded media type for query parameters and RFC 3986 for all other components. Note that only characters not permitted in a particular component are subject to encoding so, e.g., a path supplied to one of the path methods may contain matrix parameters or multiple path segments since the separators are legal characters and will not be encoded. Percent encoded values are also recognized where allowed and will not be double encoded.

Setting isBodyHtml to true allows you to use HTML tags in the message body:

msg = new MailMessage("[email protected]",
                "[email protected]", "Message from PSSP System",
                "This email sent by the PSSP system<br />" +
                "<b>this is bold text!</b>");

msg.IsBodyHtml = true;

The short answer is that scripting is unsupported in emails.

This is hardly surprising, given the obvious security risks involved with a script running inside an application that has all that personal information stored in it.

Webmail clients are mostly running the interface in JavaScript and are not keen on your email interfering with that, and desktop client filters often consider JavaScript to be an indicator of spam or phishing emails. Even in the cases where it might run, there really is little benefit to scripting in emails.

Keep your emails as straight HTML and CSS, and avoid the hassle. Here is what you can do in html emails: https://www.campaignmonitor.com/guides/coding/technologies/

For Load UserTable (List of foreign keys and the tables they reference)

Use .push:

items.push({'id':5});

Of course, if you want to make sure it's in there otherwise fail then this works:

thisTag = _tags[key];

NOTE: This will fail if the key,value pair does not exists but sometimes that is exactly what you want. This way you can catch it and do something about the error. I would only do this if I am certain that the key,value pair is or should be in the dictionary and if not I want it to know about it via the throw.

If you have specific chars should be:

Collection<Character> specificChars = Arrays.asList('A', 'D', 'E');  // more chars
char symbol = 'Y';
System.out.println(specificChars.contains(symbol));   // false
symbol = 'A';
System.out.println(specificChars.contains(symbol));   // true           

HTML represents meaning; CSS represents appearance. How you mark up text in a document is not determined by how that text appears on screen, but simply what it means. As another example, some other HTML elements, like headings, are styled font-weight: bold by default, but they are marked up using <h1>–<h6>, not <strong> or <b>.

In HTML5, you use <strong> to indicate important parts of a sentence, for example:

<p><strong>Do not touch.</strong> Contains <strong>hazardous</strong> materials.

And you use <em> to indicate linguistic stress, for example:

<p>A Gentleman: I suppose he does. But there's no point in asking.
<p>A Lady: Why not?
<p>A Gentleman: Because he doesn't row.
<p>A Lady: He doesn't <em>row</em>?
<p>A Gentleman: No. He <em>doesn't</em> row.
<p>A Lady: Ah. I see what you mean.

These elements are semantic elements that just happen to have bold and italic representations by default, but you can style them however you like. For example, in the <em> sample above, you could represent stress emphasis in uppercase instead of italics, but the functional purpose of the <em> element remains the same — to change the context of a sentence by emphasizing specific words or phrases over others:

em {
    font-style: normal;
    text-transform: uppercase;
}

Note that the original answer (below) applied to HTML standards prior to HTML5, in which <strong> and <em> had somewhat different meanings, <b> and <i> were purely presentational and had no semantic meaning whatsoever. Like <strong> and <em> respectively, they have similar presentational defaults but may be styled differently.

You use <strong> and <em> to indicate intense emphasis and normal emphasis respectively.

Or think of it this way: font-weight: bold is closer to <b> than <strong>, and font-style: italic is closer to <i> than <em>. These visual styles are purely visual: tools like screen readers aren't going to understand what bold and italic mean, but some screen readers are able to read <strong> and <em> text in a more emphasized tone.

This error appears in my android project with multiple kind of gfx files. At the end no change in the manifest file was accepted.

Because my lack of knowledge about the android devices I forget that my test device has a second User. This User also has an installed version of my app so I also have to delete the app for this user account and it works.

Swift 5 & iOS 13+ Programmatic Example

1. You must mark your function with @objc, see below example!
2. No parenthesis following after the function name! Just use #selector(name).
3. private or public doesn't matter; you can use private.

Code Example

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)
    
    let menuButtonImage = UIImage(systemName: "flame")
    let menuButton = UIBarButtonItem(image: menuButtonImage, style: .plain, target: self, action: #selector(didTapMenuButton))
    navigationItem.rightBarButtonItem = menuButton
}

@objc public func didTapMenuButton() {
    print("Hello World")
}

I can't believe none of the answers pointed to the function dirname() (available since PHP 4).

Basically, it returns the full path for the referenced object. If you use a file as a reference, the function returns the full path of the file. If the referenced object is a folder, the function will return the parent folder of that folder.

https://www.php.net/manual/en/function.dirname.php

For the current folder of the current file, use $current = dirname(__FILE__);.

For a parent folder of the current folder, simply use $parent = dirname(__DIR__);.

I often hear the question, “Should I design a base type or an interface?” The answer isn’t always clearcut.

Here are some guidelines that might help you:

¦¦ IS-A vs. CAN-DO relationship A type can inherit only one implementation. If the derived type can’t claim an IS-A relationship with the base type, don’t use a base type; use an interface. Interfaces imply a CAN-DO relationship. If the CAN-DO functionality appears to belong with various object types, use an interface. For example, a type can convert instances of itself to another type (IConvertible), a type can serialize an instance of itself (ISerializable), etc. Note that value types must be derived from System.ValueType, and therefore, they cannot be derived from an arbitrary base class. In this case, you must use a CAN-DO relationship and define an interface.

¦¦ Ease of use It’s generally easier for you as a developer to define a new type derived from a base type than to implement all of the methods of an interface. The base type can provide a lot of functionality, so the derived type probably needs only relatively small modifications to its behavior. If you supply an interface, the new type must implement all of the members.

¦¦ Consistent implementation No matter how well an interface contract is documented, it’s very unlikely that everyone will implement the contract 100 percent correctly. In fact, COM suffers from this very problem, which is why some COM objects work correctly only with Microsoft Word or with Windows Internet Explorer. By providing a base type with a good default implementation, you start off using a type that works and is well tested; you can then modify parts that need modification.

¦¦ Versioning If you add a method to the base type, the derived type inherits the new method, you start off using a type that works, and the user’s source code doesn’t even have to be recompiled. Adding a new member to an interface forces the inheritor of the interface to change its source code and recompile.

my css

TR.gray-t {background:#949494;}
h3{
    padding-top:3px;
    font:bold 12px/2px Arial;
}

my html

<TR class='gray-t'>
<TD colspan='3'><h3>KAJANG</h3>

I decrease the 2nd size in font.

padding-top is used to fix the size in IE7.

I think the easiest fix to this is to self ping your own server every 30 mins. Here's the code I use in my node.js project to prevent sleeping.

const request = require('request');
const ping = () => request('https://<my-app-name>.herokuapp.com/', (error, response, body) => {
    console.log('error:', error); // Print the error if one occurred
    console.log('statusCode:', response && response.statusCode); // Print the response status code if a response was received
    console.log('body:', body); // Print body of response received
});
setInterval(ping, 20*60*1000); // I have set to 20 mins interval

Unfortunately, the accepted answer doesn't work for me (I'm using GitHub flavoured markdown).

It occurs to me since we're adding HTML elements, why not just add an <input> instead.

| demo                                              | demo |
| ------------------------------------------------- | ---- |
| <input type="checkbox" disabled checked /> works  |      |
| <input type="checkbox" disabled /> works here too |      |

This should work in any environment cuz it's plain HTML (see FYI below).

FYI, this example was tested in VS Code markdown preview mode(GitHub flavoured), the screenshot is also taken in VS Code preview mode, It's not exactly working on GitHub.

Emoji mentioned above is a good alternative, if this doesn't work in your target environment.

$array = array('lastname', 'email', 'phone');


echo "'" . implode("','", $array) . "'";

You can group by status and select a row from the largest group:

table.GroupBy(r => r.Status).OrderByDescending(g => g.Key).First().First();

The first First() gets the first group (the set of rows with the largest status); the second First() gets the first row in that group.
If the status is always unqiue, you can replace the second First() with Single().

Here is a good example of array_keys from PHP.js library:

function array_keys (input, search_value, argStrict) {
    // Return just the keys from the input array, optionally only for the specified search_value

    var search = typeof search_value !== 'undefined',
        tmp_arr = [],
        strict = !!argStrict,
        include = true,
        key = '';

    for (key in input) {
        if (input.hasOwnProperty(key)) {
            include = true;
            if (search) {
                if (strict && input[key] !== search_value) {
                    include = false;
                }
                else if (input[key] != search_value) {
                    include = false;
                }
            }

            if (include) {
                tmp_arr[tmp_arr.length] = key;
            }
        }
    }

    return tmp_arr;
}

The same goes for array_values (from the same PHP.js library):

function array_values (input) {
    // Return just the values from the input array  

    var tmp_arr = [],
        key = '';

    for (key in input) {
        tmp_arr[tmp_arr.length] = input[key];
    }

    return tmp_arr;
}

EDIT: Removed unnecessary clauses from the code.

If you're removing a commit and don't want to keep its changes @ferit has a good solution.

If you want to add that commit to the current branch, but doesn't make sense to be part of the current pr, you can do the following instead:

1. use git rebase -i HEAD~n
2. Swap the commit you want to remove to the bottom (most recent) position
3. Save and exit
4. use git reset HEAD^ --soft to uncommit the changes and get them back in a staged state.
5. use git push --force to update the remote branch without your removed commit.

Now you'll have removed the commit from your remote, but will still have the changes locally.

The error is indeed fixed by inserting this with a type annotation as the first callback parameter. My attempt to do that was botched by simultaneously changing the callback into an arrow-function:

foo.on('error', (this: Foo, err: any) => { // DON'T DO THIS

It should've been this:

foo.on('error', function(this: Foo, err: any) {

or this:

foo.on('error', function(this: typeof foo, err: any) {

A GitHub issue was created to improve the compiler's error message and highlight the actual grammar error with this and arrow-functions.

As of Xcode 8.2.1, iOS 10, and swift 3,

You can determine the end of tableView.reloadData() easily by using a CATransaction block:

CATransaction.begin()
CATransaction.setCompletionBlock({
    print("reload completed")
    //Your completion code here
})
print("reloading")
tableView.reloadData()
CATransaction.commit()

The above also works for determining the end of UICollectionView's reloadData() and UIPickerView's reloadAllComponents().

For me was helpful next:

> apt-get install python-dev python3-dev

    final int[] positions=new int[2]; 
    Spinner sp=findViewByID(R.id.spinner);

    sp.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {

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

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

        }
    });

Normally, it's the value property

testArea.value

Or is there something I'm missing in what you need?

You can use max-height in an inline style attribute, as below:

<div class="panel panel-primary">
  <div class="panel-heading">jhdsahfjhdfhs</div>
  <div class="panel-body" style="max-height: 10;">fdoinfds sdofjohisdfj</div>
</div>

To use scrolling with content that overflows a given max-height, you can alternatively try the following:

<div class="panel panel-primary">
  <div class="panel-heading">jhdsahfjhdfhs</div>
  <div class="panel-body" style="max-height: 10;overflow-y: scroll;">fdoinfds sdofjohisdfj</div>
</div>

To restrict the height to a fixed value you can use something like this.

<div class="panel panel-primary">
  <div class="panel-heading">jhdsahfjhdfhs</div>
  <div class="panel-body" style="min-height: 10; max-height: 10;">fdoinfds sdofjohisdfj</div>
</div>

Specify the same value for both max-height and min-height (either in pixels or in points – as long as it’s consistent).

You can also put the same styles in css class in a stylesheet (or a style tag as shown below) and then include the same in your tag. See below:

Style Code:

.fixed-panel {
  min-height: 10;
  max-height: 10;
  overflow-y: scroll;
}

Apply Style :

<div class="panel panel-primary">
  <div class="panel-heading">jhdsahfjhdfhs</div>
  <div class="panel-body fixed-panel">fdoinfds sdofjohisdfj</div>
</div>

Hope this helps with your need.

You can use setInterval(), the arguments are the same.

const interval = setInterval(function() {
   // method to be executed;
 }, 5000);

clearInterval(interval); // thanks @Luca D'Amico

Instead of using the % unit – the width/height of another element – you should use vh and vw.
Your code would be:

your table {
  width: 100vw;
  height: 100vh;
}

But, if the document is smaller than 100vh or 100vw, then you need to set the size to the document's size.

(table).style.width = window.innerWidth;
(table).style.height = window.innerHeight;

How about passing the controller function with bidirectional binding? Then you can use it in the directive exactly the same way as in a regular template (I stripped irrelevant parts for simplicity):

<div ng-controller="testCtrl">

   <!-- pass the function with no arguments -->
   <test color1="color1" update-fn="updateFn"></test>
</div>

<script>
   angular.module('dr', [])
   .controller("testCtrl", function($scope) {
      $scope.updateFn = function(msg) {
         alert(msg);
      }
   })
   .directive('test', function() {
      return {
         scope: {
            updateFn: '=' // '=' bidirectional binding
         },
         template: "<button ng-click='updateFn(1337)'>Click</button>"
      }
   });
</script>

I landed at this question, because I tried the method above befire, but somehow it didn't work. Now it works perfectly.

I had a problem like you. But I am Windows 8.1 64 bit user. At first I use eclipse Kepler on my 8.1. The eclipse often become not responding when I worked on. After that, I decide to back to eclipse Juno and it works fine now.

You probably just need to see the ASCII and EXTENDED ASCII character sets. As far as I know any of these are allowed in a char/varchar field.

If you use nchar/nvarchar then it's pretty much any character in any unicode set in the world.

Though it's probably suggested to get some heavier validation via JS or on the server, HTML5 does support this via the pattern attribute.

<input type= "text" name= "name" pattern= "[0-9]"  title= "Title"/>

For Atlassian Connect Apps, use AP.navigator.reload();

See details here

The <ul> element has browser inherent padding & margin by default. In your case, Use

#footer ul {
    margin: 0; /* To remove default bottom margin */ 
    padding: 0; /* To remove default left padding */
}

or a CSS browser reset ( https://cssreset.com/ ) to deal with this.

You can't do it client-side. You'll have to do it on the server.

Edit: This answer is outdated!

As the time of this edit, HTML file API is now supported on all major browsers.

I'd provide an update with solution, but @mark.inman.winning already did it.

Keep in mind that even if it's now possible to validate on the client, you should still validate it on the server, though. All client side validations can be bypassed.

Tip for dealing with objects requiring heavy intermediate calculation: When using objects that require a lot of heavy calculation and intermediate steps to create, I often find it useful to write a chunk of code with the function to create the object, and then a separate chunk of code that gives me the option either to generate and save the object as an rmd file, or load it externally from an rmd file I have already previously saved. This is especially easy to do in R Markdown using the following code-chunk structure.

```{r Create OBJECT}

COMPLICATED.FUNCTION <- function(...) { Do heavy calculations needing lots of memory;
                                        Output OBJECT; }

```
```{r Generate or load OBJECT}

LOAD <- TRUE;
#NOTE: Set LOAD to TRUE if you want to load saved file
#NOTE: Set LOAD to FALSE if you want to generate and save

if(LOAD == TRUE) { OBJECT <- readRDS(file = 'MySavedObject.rds'); } else
                 { OBJECT <- COMPLICATED.FUNCTION(x, y, z);
                             saveRDS(file = 'MySavedObject.rds', object = OBJECT); }

```

With this code structure, all I need to do is to change LOAD depending on whether I want to generate and save the object, or load it directly from an existing saved file. (Of course, I have to generate it and save it the first time, but after this I have the option of loading it.) Setting LOAD = TRUE bypasses use of my complicated function and avoids all of the heavy computation therein. This method still requires enough memory to store the object of interest, but it saves you from having to calculate it each time you run your code. For objects that require a lot of heavy calculation of intermediate steps (e.g., for calculations involving loops over large arrays) this can save a substantial amount of time and computation.

The error indicates another process is trying to access the file. Maybe you or someone else has it open while you are attempting to write to it. "Read" or "Copy" usually doesn't cause this, but writing to it or calling delete on it would.

There are some basic things to avoid this, as other answers have mentioned:

1. In FileStream operations, place it in a using block with a FileShare.ReadWrite mode of access.

   For example:

   using (FileStream stream = File.Open(path, FileMode.Open, FileAccess.Write, FileShare.ReadWrite))
   {
   }
   

   Note that FileAccess.ReadWrite is not possible if you use FileMode.Append.

2. I ran across this issue when I was using an input stream to do a File.SaveAs when the file was in use. In my case I found, I didn't actually need to save it back to the file system at all, so I ended up just removing that, but I probably could've tried creating a FileStream in a using statement with FileAccess.ReadWrite, much like the code above.

3. Saving your data as a different file and going back to delete the old one when it is found to be no longer in use, then renaming the one that saved successfully to the name of the original one is an option. How you test for the file being in use is accomplished through the

   List<Process> lstProcs = ProcessHandler.WhoIsLocking(file);
   

   line in my code below, and could be done in a Windows service, on a loop, if you have a particular file you want to watch and delete regularly when you want to replace it. If you don't always have the same file, a text file or database table could be updated that the service always checks for file names, and then performs that check for processes & subsequently performs the process kills and deletion on it, as I describe in the next option. Note that you'll need an account user name and password that has Admin privileges on the given computer, of course, to perform the deletion and ending of processes.

4. When you don't know if a file will be in use when you are trying to save it, you can close all processes that could be using it, like Word, if it's a Word document, ahead of the save.

   If it is local, you can do this:

   ProcessHandler.localProcessKill("winword.exe");
   

   If it is remote, you can do this:

   ProcessHandler.remoteProcessKill(computerName, txtUserName, txtPassword, "winword.exe");
   

   where txtUserName is in the form of DOMAIN\user.

5. Let's say you don't know the process name that is locking the file. Then, you can do this:

   List<Process> lstProcs = new List<Process>();
   lstProcs = ProcessHandler.WhoIsLocking(file);
   
   foreach (Process p in lstProcs)
   {
       if (p.MachineName == ".")
           ProcessHandler.localProcessKill(p.ProcessName);
       else
           ProcessHandler.remoteProcessKill(p.MachineName, txtUserName, txtPassword, p.ProcessName);
   }
   

   Note that file must be the UNC path: \\computer\share\yourdoc.docx in order for the Process to figure out what computer it's on and p.MachineName to be valid.

Or you can use an arrow function to define it:

$(document).ready(() => {
  $('#bfCaptchaEntry').click(()=>{

For better browser support:

$(document).ready(function() {
  $('#bfCaptchaEntry').click(function (){

It is true that the same-origin policy prevents JavaScript from making requests across domains, but the CORS specification allows just the sort of API access you are looking for, and is supported by the current batch of major browsers.

See how to enable cross-origin resource sharing for client and server:

http://enable-cors.org/

"Cross-Origin Resource Sharing (CORS) is a specification that enables truly open access across domain-boundaries. If you serve public content, please consider using CORS to open it up for universal JavaScript/browser access."

SELECT <...> 
FROM A.tableA JOIN B.tableB 

Here is a core JavaScript function to wait for the display of an element (well, its insertion into the DOM to be more accurate).

// Call the below function
waitForElementToDisplay("#div1",function(){alert("Hi");},1000,9000);

function waitForElementToDisplay(selector, callback, checkFrequencyInMs, timeoutInMs) {
  var startTimeInMs = Date.now();
  (function loopSearch() {
    if (document.querySelector(selector) != null) {
      callback();
      return;
    }
    else {
      setTimeout(function () {
        if (timeoutInMs && Date.now() - startTimeInMs > timeoutInMs)
          return;
        loopSearch();
      }, checkFrequencyInMs);
    }
  })();
}

This call will look for the HTML tag whose id="div1" every 1000 milliseconds. If the element is found, it will display an alert message Hi. If no element is found after 9000 milliseconds, this function stops its execution.

Parameters:

1. selector: String : This function looks for the element ${selector}.
2. callback: Function : This is a function that will be called if the element is found.
3. checkFrequencyInMs: Number : This function checks whether this element exists every ${checkFrequencyInMs} milliseconds.
4. timeoutInMs : Number : Optional. This function stops looking for the element after ${timeoutInMs} milliseconds.

NB : Selectors are explained at https://developer.mozilla.org/en-US/docs/Web/API/Document/querySelector

Java 8 now supports BASE64 Encoding and Decoding. You can use the following classes: java.util.Base64, java.util.Base64.Encoder and java.util.Base64.Decoder.

Example usage:

// encode with padding
String encoded = Base64.getEncoder().encodeToString(someByteArray);

// encode without padding
String encoded = Base64.getEncoder().withoutPadding().encodeToString(someByteArray);

// decode a String
byte [] barr = Base64.getDecoder().decode(encoded); 

This error is caused by:

Y = Dataset.iloc[:,18].values

Indexing is out of bounds here most probably because there are less than 19 columns in your Dataset, so column 18 does not exist. The following code you provided doesn't use Y at all, so you can just comment out this line for now.

387 constructors?? That's your main problem. How about this instead?

public Foo(params int[] list) {...}

//Do this

int IS_NULL_PTR(char *k){
memset(&k, k, sizeof k);
if(k) { return 71; } ;
return 72;
}
int PRINT_PTR_SAFE(char *KR){
    char *E=KR;;
    if (IS_NULL_PTR(KR)==71){
        printf("%s\r\n",KR);
    } else {
        printf("%s","(null)\r\n");
    }
}
int main(int argc,char *argv[]){
    int i=0;
    char *A=malloc(sizeof(char)*9);
    ;strcpy(A,"hello world");
    for (i=((int)(A))-10;i<1e+40;i++){
        PRINT_PTR_SAFE(i);
    }

}
//Then watch the show!
//Edit as you wish. Just credit me if you really want more of this.

None of the above solutions seemed to work for me since my code is dynamically generating two containting divs and within that an un-cached image. My solution was as follows:

Please note the 'load' call on img, and the 'close' parameter in the dialog call.

var div = jQuery('<div></div>')
                  .attr({id: 'previewImage'})
                  .appendTo('body')
                  .hide();
var div2 = jQuery('<div></div>')
                  .css({
                      maxWidth: parseInt(jQuery(window).width() *.80) + 'px'
                      , maxHeight: parseInt(jQuery(window).height() *.80) + 'px'
                      , overflow: 'auto'
                  })
                  .appendTo(div);
var img = jQuery('<img>')
                  .attr({'src': url})
                  .appendTo(div2)
                  .load(function() {
                      div.dialog({
                          'modal': true
                          , 'width': 'auto'
                          , close: function() {
                               div.remove();
                          }
                      });
                  });

You aren't being very clear about what you want here, since I think @DWin's is technically correct, given your example code. I think what you really want is this:

y1 <- c(100, 200, 300, 400, 500)
y2 <- c(1, 2, 3, 4, 5)
x <- c(1, 2, 3, 4, 5)

# first plot
plot(x, y1,ylim = range(c(y1,y2)))

# Add points
points(x, y2)

DWin's solution was operating under the implicit assumption (based on your example code) that you wanted to plot the second set of points overlayed on the original scale. That's why his image looks like the points are plotted at 1, 101, etc. Calling plot a second time isn't what you want, you want to add to the plot using points. So the above code on my machine produces this:

But DWin's main point about using ylim is correct.

The often used approach with XML elements breaks in case of forbidden characters. This is an approach to use this method with any kind of character, even with the semicolon as delimiter.

The trick is, first to use SELECT SomeString AS [*] FOR XML PATH('') to get all forbidden characters properly escaped. That's the reason, why I replace the delimiter to a magic value to avoid troubles with ; as delimiter.

DECLARE @Dummy TABLE (ID INT, SomeTextToSplit NVARCHAR(MAX))
INSERT INTO @Dummy VALUES
 (1,N'A&B;C;D;E, F')
,(2,N'"C" & ''D'';<C>;D;E, F');

DECLARE @Delimiter NVARCHAR(10)=';'; --special effort needed (due to entities coding with "&code;")!

WITH Casted AS
(
    SELECT *
          ,CAST(N'<x>' + REPLACE((SELECT REPLACE(SomeTextToSplit,@Delimiter,N'§§Split$me$here§§') AS [*] FOR XML PATH('')),N'§§Split$me$here§§',N'</x><x>') + N'</x>' AS XML) AS SplitMe
    FROM @Dummy
)
SELECT Casted.ID
      ,x.value(N'.',N'nvarchar(max)') AS Part 
FROM Casted
CROSS APPLY SplitMe.nodes(N'/x') AS A(x)

The result

ID  Part
1   A&B
1   C
1   D
1   E, F
2   "C" & 'D'
2   <C>
2   D
2   E, F

Intent.FLAG_ACTIVITY_FORWARD_RESULT?

If set and this intent is being used to launch a new activity from an existing one, then the reply target of the existing activity will be transfered to the new activity.

The MaxAge of -1 signals that you want the cookie to persist for the duration of the session. You want to set MaxAge to 0 instead.

From the API documentation:

A negative value means that the cookie is not stored persistently and will be deleted when the Web browser exits. A zero value causes the cookie to be deleted.

Django also has the 'latest(field_name = None)' function that finds the latest (max. value) entry. It not only works with date fields but also with strings and integers.

You can give the field name when calling that function:

max_rated_entry = YourModel.objects.latest('rating')
return max_rated_entry.details

Or you can already give that field name in your models meta data:

from django.db import models

class YourModel(models.Model):
    #your class definition
    class Meta:
        get_latest_by = 'rating'

Now you can call 'latest()' without any parameters:

max_rated_entry = YourModel.objects.latest()
return max_rated_entry.details

Inline elements:

1. respect left & right margins and padding, but not top & bottom
2. cannot have a width and height set
3. allow other elements to sit to their left and right.
4. see very important side notes on this here.

Block elements:

1. respect all of those
2. force a line break after the block element
3. acquires full-width if width not defined

Inline-block elements:

1. allow other elements to sit to their left and right
2. respect top & bottom margins and padding
3. respect height and width

From W3Schools:

• An inline element has no line break before or after it, and it tolerates HTML elements next to it.

• A block element has some whitespace above and below it and does not tolerate any HTML elements next to it.

• An inline-block element is placed as an inline element (on the same line as adjacent content), but it behaves as a block element.

When you visualize this, it looks like this:

In June 2016 Instagram made most of the functionality of their API available only to applications that have passed a review process. They still however provide JSON data through the web interface, and you can add the parameter __a=1 to a URL to only include the JSON data.

max=
while :;do
  c=$(curl -s "https://www.instagram.com/username/?__a=1&max_id=$max")
  jq -r '.user.media.nodes[]?|.display_src'<<<"$c"
  max=$(jq -r .user.media.page_info.end_cursor<<<"$c")
  jq -e .user.media.page_info.has_next_page<<<"$c">/dev/null||break
done

Edit: As mentioned in the comment by alnorth29, the max_id parameter is now ignored. Instagram also changed the format of the response, and you need to perform additional requests to get the full-size URLs of images in the new-style posts with multiple images per post. You can now do something like this to list the full-size URLs of images on the first page of results:

c=$(curl -s "https://www.instagram.com/username/?__a=1")
jq -r '.graphql.user.edge_owner_to_timeline_media.edges[]?|.node|select(.__typename!="GraphSidecar").display_url'<<<"$c"
jq -r '.graphql.user.edge_owner_to_timeline_media.edges[]?|.node|select(.__typename=="GraphSidecar")|.shortcode'<<<"$c"|while read l;do
  curl -s "https://www.instagram.com/p/$l?__a=1"|jq -r '.graphql.shortcode_media|.edge_sidecar_to_children.edges[]?.node|.display_url'
done

To make a list of the shortcodes of each post made by the user whose profile is opened in the frontmost tab in Safari, I use a script like this:

sjs(){ osascript -e'{on run{a}','tell app"safari"to do javascript a in document 1',end} -- "$1";}

while :;do
  sjs 'o="";a=document.querySelectorAll(".v1Nh3 a");for(i=0;e=a[i];i++){o+=e.href+"\n"};o'>>/tmp/a
  sjs 'window.scrollBy(0,window.innerHeight)'
  sleep 1
done

I am currently using https://github.com/kevinsawicki/http-request I like their simplicity and the way examples are shown, but mostly I was sold when I read:

What are the dependencies?

None. The goal of this library is to be a single class class with some inner static classes. The test project does require Jetty in order to test requests against an actual HTTP server implementation.

which sorted out some problems on a java 1.6 project. As for decoding json into objects gson is just invincible :)

In my case, the command that best suited me was:

jupyter nbconvert --execute --clear-output <notebook>.ipynb

Why? This command does not create extra files (just like a .py file) and the output of the cells is overwritten everytime the notebook is executed.

If you run:

jupyter nbconvert --help

--clear-output Clear output of current file and save in place, overwriting the existing notebook.

This lifecycle method is invoked as soon as the updating happens. The most common use case for the componentDidUpdate() method is updating the DOM in response to prop or state changes.

You can call setState() in this lifecycle, but keep in mind that you will need to wrap it in a condition to check for state or prop changes from previous state. Incorrect usage of setState() can lead to an infinite loop. Take a look at the example below that shows a typical usage example of this lifecycle method.

componentDidUpdate(prevProps) {
 //Typical usage, don't forget to compare the props
 if (this.props.userName !== prevProps.userName) {
   this.fetchData(this.props.userName);
 }
}

Notice in the above example that we are comparing the current props to the previous props. This is to check if there has been a change in props from what it currently is. In this case, there won’t be a need to make the API call if the props did not change.

Recommended way for versions of PHP >= 5.4.0 , PHP 7

if (session_status() === PHP_SESSION_NONE) {
    session_start();
}

Reference: http://www.php.net/manual/en/function.session-status.php

For versions of PHP < 5.4.0

if(session_id() == '') {
    session_start();
}

You can use

<?php the_category(', '); ?>

which would output them in a comma separated list.

You can also do the same for tags as well:

<?php the_tags('<em>:</em>', ', ', ''); ?>

tr.rowhighlight td, tr.rowhighlight th{
    background-color:#f0f8ff;
}

Although I'm sure @Ben Jackson's asnwer with Option(getObject).foreach is the preferred way of doing it, I like to use an AnyRef pimp that allows me to write:

getObject ifNotNull ( QueueManager.add(_) )

I find it reads better.

And, in a more general way, I sometimes write

val returnVal = getObject ifNotNull { obj =>
  returnSomethingFrom(obj)
} otherwise {
  returnSomethingElse
}

... replacing ifNotNull with ifSome if I'm dealing with an Option. I find it clearer than first wrapping in an option and then pattern-matching it.

(For the implementation, see Implementing ifTrue, ifFalse, ifSome, ifNone, etc. in Scala to avoid if(...) and simple pattern matching and the Otherwise0/Otherwise1 classes.)

Drag-And-Drop

Easiest way for a lazy Mac user like me: Drag-and-drop the startup.sh file from the Finder to the Terminal window and press Return.

To shutdown Tomcat, do the same with shutdown.sh.

You can delete all the .bat files as they are only for a Windows PC, of no use on a Mac to other Unix computer. I delete them as it makes it easier to read that folder's listing.

File Permissions

I find that a fresh Tomcat download will not run on my Mac because of file permission restrictions throwing errors during startup. I use the BatChmod app which wraps a GUI around the equivelant Unix commands to reset file permissions.

Port-Forwarding

Unix systems protect access to ports numbered under 1024. So if you want to use port 80 with Tomcat you will need to learn how to do "port-forwarding" to forward incoming requests to port 8080 where Tomcat listens by default. To do port-forwarding, you issue commands to the packet-filtering (firewall) app built into Mac OS X (and BSD). In the old days we used ipfw. In Mac OS X 10.7 (Lion) and later Apple is moving to a newer tool, pf.

For solving my issue on Linux don't have a JDK, I just download the JDK and upload to the Linux server, and type: tar xvf jdk-8u45-linux-x64.tar.gz

For anyone who make it in bigger scale, you might have also check how many file descriptors you have. It will throw this error if you ran out at bad moment.

Ok, so the easiest method to create several plots is this:

import matplotlib.pyplot as plt
x=[[1,2,3,4],[1,2,3,4],[1,2,3,4],[1,2,3,4]]
y=[[1,2,3,4],[1,2,3,4],[1,2,3,4],[1,2,3,4]]
for i in range(len(x)):
    plt.figure()
    plt.plot(x[i],y[i])
    # Show/save figure as desired.
    plt.show()
# Can show all four figures at once by calling plt.show() here, outside the loop.
#plt.show()

Note that you need to create a figure every time or pyplot will plot in the first one created.

If you want to create several data series all you need to do is:

import matplotlib.pyplot as plt
plt.figure()
x=[[1,2,3,4],[1,2,3,4],[1,2,3,4],[1,2,3,4]]
y=[[1,2,3,4],[2,3,4,5],[3,4,5,6],[7,8,9,10]]
plt.plot(x[0],y[0],'r',x[1],y[1],'g',x[2],y[2],'b',x[3],y[3],'k')

You could automate it by having a list of colours like ['r','g','b','k'] and then just calling both entries in this list and corresponding data to be plotted in a loop if you wanted to. If you just want to programmatically add data series to one plot something like this will do it (no new figure is created each time so everything is plotted in the same figure):

import matplotlib.pyplot as plt
x=[[1,2,3,4],[1,2,3,4],[1,2,3,4],[1,2,3,4]]
y=[[1,2,3,4],[2,3,4,5],[3,4,5,6],[7,8,9,10]]
colours=['r','g','b','k']
plt.figure() # In this example, all the plots will be in one figure.    
for i in range(len(x)):
    plt.plot(x[i],y[i],colours[i])
plt.show()

Hope this helps. If anything matplotlib has a very good documentation page with plenty of examples.

17 Dec 2019: added plt.show() and plt.figure() calls to clarify this part of the story.

I am Using this

String timeStamp = new SimpleDateFormat("dd/MM/yyyy_HH:mm:ss").format(Calendar.getInstance().getTime());
System.out.println(timeStamp);

i don t know what solution is better, but i use this:

String[] ext = "*.ext1|*.ext2".Split('|');

            List<String> files = new List<String>();
            foreach (String tmp in ext)
            {
                files.AddRange(Directory.GetFiles(dir, tmp, SearchOption.AllDirectories));
            }

slicing operator. http://docs.python.org/tutorial/introduction.html#strings and scroll down a bit

Example from google

<script type="text/javascript">
  (function() {
    var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true;
    po.src = 'https://apis.google.com/js/plusone.js?onload=onLoadCallback';
    var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s);
  })();
</script>

you probably forgot to use "".

For exemple:

$_array[text] = $_var;

change to:

$_array["text"] = $_var;

` Please include either of these:

`#include<sstream>`

using std::istringstream; 

Use this

Let say Application Test.exe is running and function is foo() in form1 [basically it is class form1], then above code will generate below response.

string s1 = System.Reflection.MethodBase.GetCurrentMethod().DeclaringType.Name;

This will return .

s1 = "TEST.form1"

for function name:

string s1 = System.Reflection.MethodBase.GetCurrentMethod().Name;

will return

s1 = foo 

Note if you want to use this in exception use :

catch (Exception ex)
{

    MessageBox.Show(ex.StackTrace );

}

Usage when using auto layout:

class CustomView: UIView {

    override func awakeFromNib() {
        super.awakeFromNib()
    }

    override func layoutSubviews() {
        addBottomBorderWithColor(color: UIColor.white, width: 1)
    }
}

I can see what @Þaw mentioned :

$ENROLLEES = $this->load->database('ENROLLEES', TRUE);
$ACCOUNTS = $this->load->database('ACCOUNTS', TRUE);

CodeIgniter supports multiple databases. You need to keep both database reference in separate variable as you did above. So far you are right/correct.

Next you need to use them as below:

$ENROLLEES->query();
$ENROLLEES->result();

and

$ACCOUNTS->query();
$ACCOUNTS->result();

Instead of using

$this->db->query();
$this->db->result();

See this for reference: http://ellislab.com/codeigniter/user-guide/database/connecting.html

According to it

No value was specified for the AUTO_INCREMENT column, so MySQL assigned sequence numbers automatically. You can also explicitly assign NULL or 0 to the column to generate sequence numbers.

I asume you have connected to your database already.

$sql = "SELECT * FROM my_table";
$result = mysql_query($sql);

$row = 1; // 1-based index
while($row_data = mysql_fetch_assoc($result)) {
    $col = 0;
    foreach($row_data as $key=>$value) {
        $objPHPExcel->getActiveSheet()->setCellValueByColumnAndRow($col, $row, $value);
        $col++;
    }
    $row++;
}

Try this:

String yourVal = "20.5";
float a = (Float.valueOf(yourVal)).floatValue(); 
System.out.println(a);

Here's my ultimate answer to this.

Also apparently javascript's new Date(year, month, day) constructor doesn't account for leap seconds too.

// Parses an Excel Date ("serial") into a
// corresponding javascript Date in UTC+0 timezone.
//
// Doesn't account for leap seconds.
// Therefore is not 100% correct.
// But will do, I guess, since we're
// not doing rocket science here.
//
// https://www.pcworld.com/article/3063622/software/mastering-excel-date-time-serial-numbers-networkdays-datevalue-and-more.html
// "If you need to calculate dates in your spreadsheets,
//  Excel uses its own unique system, which it calls Serial Numbers".
//
lib.parseExcelDate = function (excelSerialDate) {
  // "Excel serial date" is just
  // the count of days since `01/01/1900`
  // (seems that it may be even fractional).
  //
  // The count of days elapsed
  // since `01/01/1900` (Excel epoch)
  // till `01/01/1970` (Unix epoch).
  // Accounts for leap years
  // (19 of them, yielding 19 extra days).
  const daysBeforeUnixEpoch = 70 * 365 + 19;

  // An hour, approximately, because a minute
  // may be longer than 60 seconds, see "leap seconds".
  const hour = 60 * 60 * 1000;

  // "In the 1900 system, the serial number 1 represents January 1, 1900, 12:00:00 a.m.
  //  while the number 0 represents the fictitious date January 0, 1900".
  // These extra 12 hours are a hack to make things
  // a little bit less weird when rendering parsed dates.
  // E.g. if a date `Jan 1st, 2017` gets parsed as
  // `Jan 1st, 2017, 00:00 UTC` then when displayed in the US
  // it would show up as `Dec 31st, 2016, 19:00 UTC-05` (Austin, Texas).
  // That would be weird for a website user.
  // Therefore this extra 12-hour padding is added
  // to compensate for the most weird cases like this
  // (doesn't solve all of them, but most of them).
  // And if you ask what about -12/+12 border then
  // the answer is people there are already accustomed
  // to the weird time behaviour when their neighbours
  // may have completely different date than they do.
  //
  // `Math.round()` rounds all time fractions
  // smaller than a millisecond (e.g. nanoseconds)
  // but it's unlikely that an Excel serial date
  // is gonna contain even seconds.
  //
  return new Date(Math.round((excelSerialDate - daysBeforeUnixEpoch) * 24 * hour) + 12 * hour);
};

Your specific error is with line 11:

awk 'BEGIN{sum+=$2}'

This is a line where awk is invoked, and its BEGIN block is specified - but you are already within a awk script, so you do not need to specify awk. Also you want to run sum+=$2 on each line of input, so you do not want it within a BEGIN block. Hence the line should simply read:

sum+=$2

You also do not need the lines:

x=sum
read name

the first just creates a synonym to sum named x and I'm not sure what the second does, but neither are needed.

This would make your awk script:

#!/bin/awk

### This script currently prints the total number of rows processed.
### You must edit this script to print the average of the 2nd column
### instead of the number of rows.

# This block of code is executed for each line in the file
{
    sum+=$2
    # The script should NOT print out a value for each line
}
# The END block is processed after the last line is read
END {
    # NR is a variable equal to the number of rows in the file
    print "Average: " sum/ NR
    # Change this to print the Average instead of just the number of rows
}

Jonathan Leffler's answer gives the awk one liner which represents the same fixed code, with the addition of checking that there are at least 1 lines of input (this stops any divide by zero error). If

From wechat api doc:

curl -F [email protected] "http://file.api.wechat.com/cgi-bin/media/upload?access_token=ACCESS_TOKEN&type=TYPE"

Translate the command above to python:

import requests
url = 'http://file.api.wechat.com/cgi-bin/media/upload?access_token=ACCESS_TOKEN&type=TYPE'
files = {'media': open('test.jpg', 'rb')}
requests.post(url, files=files)

For windows users:

Go to Task Manager directly with CTRL+SHIFT+ESC key combination.

Kill the "java.exe" processes by right clicking and selecting "End Task".

Here is another way, without the need for nesting the repeaters.

From the Angularjs docs:

It is possible to get ngRepeat to iterate over the properties of an object using the following syntax:

<div ng-repeat="(key, value) in steps"> {{key}} : {{value}} </div>

Goto Window->Preferences, search for Launching.

Select the "Terminate and Relaunch while launching" option.

Press Apply.

Just for completeness, since MySQL and Postgres have already been mentioned: With SQLite, use "pragma table_info()"

sqlite> pragma table_info('table_name');
cid         name        type        notnull     dflt_value  pk        
----------  ----------  ----------  ----------  ----------  ----------
0           id          integer     99                      1         
1           name                    0                       0         

It seems the docs/tool have been updated and you can now add the image tag to your script. This was successful for me.

Example:

version: '2'
services:

  baggins.api.rest:
    image: my.image.name:rc2
    build:
      context: ../..
      dockerfile: app/Docker/Dockerfile.release

I'd look into using the System.TimeZoneInfo class if you are in .NET 3.5. See http://msdn.microsoft.com/en-us/library/system.timezoneinfo.aspx. This should take into account the daylight savings changes correctly.

// Coordinated Universal Time string from 
// DateTime.Now.ToUniversalTime().ToString("u");
string date = "2009-02-25 16:13:00Z"; 
// Local .NET timeZone.
DateTime localDateTime = DateTime.Parse(date); 
DateTime utcDateTime = localDateTime.ToUniversalTime();

// ID from: 
// "HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Time Zone"
// See http://msdn.microsoft.com/en-us/library/system.timezoneinfo.id.aspx
string nzTimeZoneKey = "New Zealand Standard Time";
TimeZoneInfo nzTimeZone = TimeZoneInfo.FindSystemTimeZoneById(nzTimeZoneKey);
DateTime nzDateTime = TimeZoneInfo.ConvertTimeFromUtc(utcDateTime, nzTimeZone);

It means that servlet jar is missing .

check the libraries for your project. Configure your buildpath download **

servlet-api.jar

** and import it in your project.

a less-jquerish approach:

$('#mytable tr').each(function() {
    if (!this.rowIndex) return; // skip first row
    var customerId = this.cells[0].innerHTML;
});

this can obviously be changed to work with not-the-first cells.

auto_now=True didn't work for me in Django 1.4.1, but the below code saved me. It's for timezone aware datetime.

from django.utils.timezone import get_current_timezone
from datetime import datetime

class EntryVote(models.Model):
    voted_on = models.DateTimeField(auto_now=True)

    def save(self, *args, **kwargs):
        self.voted_on = datetime.now().replace(tzinfo=get_current_timezone())
        super(EntryVote, self).save(*args, **kwargs)

You can use the connection string as follows and you only need to add your database name.

string connetionString = "Data Source=.;Initial Catalog=DB name;Integrated Security=True;MultipleActiveResultSets=True";

Use this solution

animate(document.documentElement, 'scrollTop', 0, 200);

See,

There are two ways to convert an RDD to DF in Spark.

toDF() and createDataFrame(rdd, schema)

I will show you how you can do that dynamically.

toDF()

The toDF() command gives you the way to convert an RDD[Row] to a Dataframe. The point is, the object Row() can receive a **kwargs argument. So, there is an easy way to do that.

from pyspark.sql.types import Row

#here you are going to create a function
def f(x):
    d = {}
    for i in range(len(x)):
        d[str(i)] = x[i]
    return d

#Now populate that
df = rdd.map(lambda x: Row(**f(x))).toDF()

This way you are going to be able to create a dataframe dynamically.

createDataFrame(rdd, schema)

Other way to do that is creating a dynamic schema. How?

This way:

from pyspark.sql.types import StructType
from pyspark.sql.types import StructField
from pyspark.sql.types import StringType

schema = StructType([StructField(str(i), StringType(), True) for i in range(32)])

df = sqlContext.createDataFrame(rdd, schema)

This second way is cleaner to do that...

So this is how you can create dataframes dynamically.

This function worked perfectly for me. It detects Edge as well.

Originally from this Codepen:

https://codepen.io/gapcode/pen/vEJNZN

/**
 * detect IE
 * returns version of IE or false, if browser is not Internet Explorer
 */
function detectIE() {
  var ua = window.navigator.userAgent;

  // Test values; Uncomment to check result …

  // IE 10
  // ua = 'Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.2; Trident/6.0)';

  // IE 11
  // ua = 'Mozilla/5.0 (Windows NT 6.3; Trident/7.0; rv:11.0) like Gecko';

  // Edge 12 (Spartan)
  // ua = 'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/39.0.2171.71 Safari/537.36 Edge/12.0';

  // Edge 13
  // ua = 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/46.0.2486.0 Safari/537.36 Edge/13.10586';

  var msie = ua.indexOf('MSIE ');
  if (msie > 0) {
    // IE 10 or older => return version number
    return parseInt(ua.substring(msie + 5, ua.indexOf('.', msie)), 10);
  }

  var trident = ua.indexOf('Trident/');
  if (trident > 0) {
    // IE 11 => return version number
    var rv = ua.indexOf('rv:');
    return parseInt(ua.substring(rv + 3, ua.indexOf('.', rv)), 10);
  }

  var edge = ua.indexOf('Edge/');
  if (edge > 0) {
    // Edge (IE 12+) => return version number
    return parseInt(ua.substring(edge + 5, ua.indexOf('.', edge)), 10);
  }

  // other browser
  return false;
}

Then you can use if (detectIE()) { /* do IE stuff */ } in your code.

if somebody still has a problem the only thing working perfectly for me by useing (loaded.bs.modal) :

 $('#editModal').on('loaded.bs.modal', function () {
       console.log('edit modal loaded');

       $('.datepicker').datepicker({
            dateFormat: 'yy-mm-dd',
            clearBtn: true,
            rtl: false,
            todayHighlight: true,
            toggleActive: true,
            changeYear: true,
            changeMonth: true
        });
});

When working with continuations I find it useful to think of the place where I write .ContinueWith as the place from which execution immediately continues to the statements following it, not the statements 'inside' it. In that case it becomes clear that you would get an empty string returned in Send. If your only processing of the response is writing it to the console, you don't need any Wait in Ito's solution - the console printout will happen without waits but both Send and Print should return void in that case. Run this in console app and you will get printout of the page.

IMO, waits and Task.Result calls (which block) are necessary sometimes, depending on your desired flow of control, but more often they are a sign that you don't really use asynchronous functionality correctly.

namespace TaskTest
{
    class Program
    {
        static void Main(string[] args)
        {
            Send();
            Console.WriteLine("Press Enter to exit");
            Console.ReadLine();
        }

        private static void Send()
        {
            HttpClient client = new HttpClient();
            Task<HttpResponseMessage> responseTask = client.GetAsync("http://google.com");
            responseTask.ContinueWith(x => Print(x));
        }

        private static void Print(Task<HttpResponseMessage> httpTask)
        {
            Task<string> task = httpTask.Result.Content.ReadAsStringAsync();
            Task continuation = task.ContinueWith(t =>
            {
                Console.WriteLine("Result: " + t.Result);
            });
        }
    }
}

Here's another using the zip function.

While I have tested both the Codes in respective versions.

private List<String> DirSearch(string sDir)
{
    List<String> files = new List<String>();
    try
    {
        foreach (string f in Directory.GetFiles(sDir))
        {
            files.Add(f);
        }
        foreach (string d in Directory.GetDirectories(sDir))
        {
            files.AddRange(DirSearch(d));
        }
    }
    catch (System.Exception excpt)
    {
        MessageBox.Show(excpt.Message);
    }

    return files;
}

and if you don't want to load the entire list in memory and avoid blocking you may take a look at the following answer.

For me the problem is with Defective USB Cable. I have tried those above all answers. Nothing gives me any fix. But finally i came to know the problem is because of my usb cable while changing the usb cable. While connecting through the usb cable the phone is charging but the drivers are not installed. Some usb cable don't have the option for that. So while buying check it and buy.

document.body.style.cursor = 'cursorurl';

Unfortunately, this is not a trivial thing to solve for the general case. The easiest thing would be to add a css-style property "float: right;" to your 200px div, however, this would also cause your "main"-div to actually be full width and any text in there would float around the edge of the 200px-div, which often looks weird, depending on the content (pretty much in all cases except if it's a floating image).

EDIT: As suggested by Dom, the wrapping problem could of course be solved with a margin. Silly me.

You should not try to use perfmon, task manager or any tool like that to determine memory leaks. They are good for identifying trends, but not much else. The numbers they report in absolute terms are too vague and aggregated to be useful for a specific task such as memory leak detection.

A previous reply to this question has given a great explanation of what the various types are.

You ask about a tool recommendation: I recommend Memory Validator. Capable of monitoring applications that make billions of memory allocations.

http://www.softwareverify.com/cpp/memory/index.html

Disclaimer: I designed Memory Validator.

Enums are not actual classes, even if they look like it. Internally, they are treated just like their underlying type (by default Int32). Therefore, you can only do this by "copying" single values from one enum to another and casting them to their integer number to compare them for equality.

If you have a JSON string and want to "prettify" it, but don't want to serialise it to and from a known C# type then the following does the trick (using JSON.NET):

using System;
using System.IO;
using Newtonsoft.Json;

class JsonUtil
{
    public static string JsonPrettify(string json)
    {
        using (var stringReader = new StringReader(json))
        using (var stringWriter = new StringWriter())
        {
            var jsonReader = new JsonTextReader(stringReader);
            var jsonWriter = new JsonTextWriter(stringWriter) { Formatting = Formatting.Indented };
            jsonWriter.WriteToken(jsonReader);
            return stringWriter.ToString();
        }
    }
}

This will be an ongoing command until the process is finished so open another shell/terminal window, log in without a password:

$ mysql -u root

mysql> UPDATE mysql.user SET Password=PASSWORD('password') WHERE User='root';

Start MySQL

sudo /usr/local/mysql/support-files/mysql.server start

I will suggest you to use ClientID of HiddenField. first Register its client Id in any Javascript Variable from codebehind, then use it in clientside script. as:

.cs file code:

ClientScript.RegisterStartupScript(this.GetType(), "clientids", "var hdntxtbxTaksit=" + hdntxtbxTaksit.ClientID, true);

and then use following code in JS:

document.getElementById(hdntxtbxTaksit).value= ""; 

auto-alignment shortcut key Ctrl+Shift+F

to change the shortcut keys Goto Window > Preferences > Java > Editor > Save Actions

Obfuscating the value by using the CustomFormat property, using checkbox cbEnableEndDate as the flag to indicate whether other code should ignore the value:

If dateTaskEnd > Date.FromOADate(0) Then
    dtTaskEnd.Format = DateTimePickerFormat.Custom
    dtTaskEnd.CustomFormat = "yyyy-MM-dd"
    dtTaskEnd.Value = dateTaskEnd 
    dtTaskEnd.Enabled = True
    cbEnableEndDate.Checked = True
Else
    dtTaskEnd.Format = DateTimePickerFormat.Custom
    dtTaskEnd.CustomFormat = " "
    dtTaskEnd.Value = Date.FromOADate(0)
    dtTaskEnd.Enabled = False
    cbEnableEndDate.Checked = False
End If

The timezone name is the only reliable way to specify the timezone.

You can find a list of timezone names here: http://en.wikipedia.org/wiki/List_of_tz_database_time_zones Note that this list contains a lot of alias names, such as US/Eastern for the timezone that is properly called America/New_York.

If you programatically want to create this list from the zoneinfo database you can compile it from the zone.tab file in the zoneinfo database. I don't think pytz has an API to get them, and I also don't think it would be very useful.

For AngularUI Router users:

<a ui-sref-active="active" ui-sref="app">

And that will place an active class on the object that is selected.

This is very much valid for WinForms. However, in WPF you need to do things differently, and it is easer. Set the IsDefault property of the Button relevant to this text-area as true.

Once you are done capturing the enter key, do not forget to toggle the properties accordingly.

Hi this query works for me,

select * from person where dob between '2011-01-01' and '2011-01-31 23:59:59'

One can also use requests if we would like to access a web page using proxies. Python 3 code:

>>> import requests
>>> url = 'http://www.google.com'
>>> proxy = '169.50.87.252:80'
>>> requests.get(url, proxies={"http":proxy})
<Response [200]>

More than one proxies can also be added.

>>> proxy1 = '169.50.87.252:80'
