Please note that 4.0 is not sufficient since ListValuedMap, was introduced in version 4.1.

You need to use this maven repository link for version 4.1. Replicated below for convenience

 <!-- https://mvnrepository.com/artifact/org.apache.commons/commons-collections4 -->
 <dependency>
   <groupId>org.apache.commons</groupId>
   <artifactId>commons-collections4</artifactId>

If you are processing in rows with cellIterator....then this worked for me ....

  DataFormatter formatter = new DataFormatter();   
  while(cellIterator.hasNext())
  {                         
        cell = cellIterator.next();
        String val = "";            
        switch(cell.getCellType()) 
        {
            case Cell.CELL_TYPE_NUMERIC:
                val = String.valueOf(formatter.formatCellValue(cell));
                break;
            case Cell.CELL_TYPE_STRING:
                val = formatter.formatCellValue(cell);
                break;
        }
    .....
    .....
  }

Sometimes using row.getLastCellNum() gives you a higher value than what is actually filled in the file.
I used the method below to get the last column index that contains an actual value.

private int getLastFilledCellPosition(Row row) {
        int columnIndex = -1;

        for (int i = row.getLastCellNum() - 1; i >= 0; i--) {
            Cell cell = row.getCell(i);

            if (cell == null || CellType.BLANK.equals(cell.getCellType()) || StringUtils.isBlank(cell.getStringCellValue())) {
                continue;
            } else {
                columnIndex = cell.getColumnIndex();
                break;
            }
        }

        return columnIndex;
    }

With Scala there is a nice Wrapper spoiwo

You can do it like this:

Workbook(mySheet.withColumns(
      Column(autoSized = true),
      Column(width = new Width(100, WidthUnit.Character)),
      Column(width = new Width(100, WidthUnit.Character)))
    )

checkout the example here

http://svn.apache.org/repos/asf/poi/trunk/src/examples/src/org/apache/poi/ss/examples/BusinessPlan.java

style.setFillForegroundColor(IndexedColors.LIGHT_CORNFLOWER_BLUE.getIndex());

Slot free in NPOI excel indexedcolors from 57+

            Color selColor;

        var wb = new HSSFWorkbook();

        var sheet = wb.CreateSheet("NPOI");
        var style = wb.CreateCellStyle();
        var font = wb.CreateFont();
        var palette = wb.GetCustomPalette();

        short indexColor = 57; 
        palette.SetColorAtIndex(indexColor, (byte)selColor.R, (byte)selColor.G, (byte)selColor.B);

        font.Color = palette.GetColor(indexColor).Indexed;

SelThroughJava's answer was very helpful I had to modify a bit to my code to be worked . I used https://mvnrepository.com/artifact/org.apache.poi/poi and https://mvnrepository.com/artifact/org.testng/testng as dependencies . Full code is given below with exact imports.

 import java.io.FileInputStream;
    import java.io.FileNotFoundException;
    import java.io.IOException;

    import org.apache.poi.xssf.usermodel.XSSFWorkbook;


    public class ReadExcelFormulaValue {

        private static final CellType NUMERIC = null;
        public static void main(String[] args) {
            try {
                readFormula();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
        public static void readFormula() throws IOException {
            FileInputStream fis = new FileInputStream("C:eclipse-workspace\\sam-webdbriver-diaries\\resources\\tUser_WS.xls");
            org.apache.poi.ss.usermodel.Workbook workbook = WorkbookFactory.create(fis);
            org.apache.poi.ss.usermodel.Sheet sheet = workbook.getSheetAt(0);

            FormulaEvaluator evaluator = workbook.getCreationHelper().createFormulaEvaluator();

            CellReference cellReference = new CellReference("G2"); // pass the cell which contains the formula
            Row row = sheet.getRow(cellReference.getRow());
            Cell cell = row.getCell(cellReference.getCol());

            CellValue cellValue = evaluator.evaluate(cell);
            System.out.println("Cell type month  is "+cellValue.getCellTypeEnum());
            System.out.println("getNumberValue month is  "+cellValue.getNumberValue());     
          //  System.out.println("getStringValue "+cellValue.getStringValue());


            cellReference = new CellReference("H2"); // pass the cell which contains the formula
             row = sheet.getRow(cellReference.getRow());
             cell = row.getCell(cellReference.getCol());

            cellValue = evaluator.evaluate(cell);
            System.out.println("getNumberValue DAY is  "+cellValue.getNumberValue());    


        }

    }

Pretty sure that this exception is thrown when the Excel file is either password protected or the file itself is corrupted. If you just want to read a .xlsx file, try my code below. It's a lot more shorter and easier to read.

import org.apache.poi.ss.usermodel.WorkbookFactory;
import org.apache.poi.ss.usermodel.Workbook;
import org.apache.poi.ss.usermodel.Sheet;
//.....

static final String excelLoc = "C:/Documents and Settings/Users/Desktop/testing.xlsx";

public static void ReadExcel() {
InputStream inputStream = null;
   try {
        inputStream = new FileInputStream(new File(excelLoc));
        Workbook wb = WorkbookFactory.create(inputStream);
        int numberOfSheet = wb.getNumberOfSheets();

        for (int i = 0; i < numberOfSheet; i++) {
             Sheet sheet = wb.getSheetAt(i);
             //.... Customize your code here
             // To get sheet name, try -> sheet.getSheetName()
        }
   } catch {}
}

http://poi.apache.org/spreadsheet/quick-guide.html#CreateDateCells

CellStyle cellStyle = wb.createCellStyle();
CreationHelper createHelper = wb.getCreationHelper();
cellStyle.setDataFormat(
    createHelper.createDataFormat().getFormat("m/d/yy h:mm"));
cell = row.createCell(1);
cell.setCellValue(new Date());
cell.setCellStyle(cellStyle);

I came across the same issue recently. I had to insert new rows in a document with hidden rows and faced the same issues with you. After some search and some emails in apache poi list, it seems like a bug in shiftrows() when a document has hidden rows.

May be by:-

    for(Row row : sheet) {          
        for(Cell cell : row) {              
            System.out.print(cell.getStringCellValue());

        }
    }       

For specific type of cell you can try:

switch (cell.getCellType()) {
case Cell.CELL_TYPE_STRING:
    cellValue = cell.getStringCellValue();
    break;

case Cell.CELL_TYPE_FORMULA:
    cellValue = cell.getCellFormula();
    break;

case Cell.CELL_TYPE_NUMERIC:
    if (DateUtil.isCellDateFormatted(cell)) {
        cellValue = cell.getDateCellValue().toString();
    } else {
        cellValue = Double.toString(cell.getNumericCellValue());
    }
    break;

case Cell.CELL_TYPE_BLANK:
    cellValue = "";
    break;

case Cell.CELL_TYPE_BOOLEAN:
    cellValue = Boolean.toString(cell.getBooleanCellValue());
    break;

}

You can use setColumnWidth() if you want to expand your cell more.

If you know the cell number, then i would recommend using getDateCellValue() method Here's an example for the same that worked for me - java.util.Date date = row.getCell().getDateCellValue(); System.out.println(date);

Google search found me this article, and I did not see the following "personal solution" discussed.

My recent annoyance with Python 3.7 on Windows Subsystem for Linux is that: on two machines with the same Pandas library, one gives me segmentation fault and the other reports warning. It was not clear which one was newer, but "re-installing" pandas solves the problem.

Command that I ran on the buggy machine.

conda install pandas

More details: I was running identical scripts (synced through Git), and both are Windows 10 machine with WSL + Anaconda. Here go the screenshots to make the case. Also, on the machine where command-line python will complain about Segmentation fault (core dumped), Jupyter lab simply restarts the kernel every single time. Worse still, no warning was given at all.

Updates a few months later: I quit hosting Jupyter servers on Windows machine. I now use WSL on Windows to fetch remote ports opened on a Linux server and run all my jobs on the remote Linux machine. I have never experienced any execution error for a good number of months :)

Try to match all version:

compileSdkVersion 23
buildToolsVersion '23.0.0'
targetSdkVersion 23
compile 'com.android.support:appcompat-v7:23.0.0'

It's work for me.

$(':text').attr("disabled", "disabled"); sets all textbox to disabled mode. You can do in another way like giving each textbox id. By doing this code weight will be more and performance issue will be there.

So better have $(':text').attr("disabled", "disabled"); approach.

Try this (see comments in code):

function fixInteger(el) {
    // this is element's value selector, you should use your own
    value = $(el).val();
    if (value == '') {
        value = 0;
    }
    newValue = parseInt(value);
    // if new value is Nan (when input is a string with no integers in it)
    if (isNaN(newValue)) {
        value = 0;
        newValue = parseInt(value);
    }
    // apply new value to element
    $(el).val(newValue);
}

function fixPrice(el) {
    // this is element's value selector, you should use your own
    value = $(el).val();
    if (value == '') {
        value = 0;
    }
    newValue = parseFloat(value.replace(',', '.')).toFixed(2);
    // if new value is Nan (when input is a string with no integers in it)
    if (isNaN(newValue)) {
        value = 0;
        newValue = parseFloat(value).toFixed(2);
    }
    // apply new value to element
    $(el).val(newValue);
}

I had the same Issue, I checked the php.net site. And found the right format.
This is my updated code.

$headers = 'MIME-Version: 1.0' . "\r\n";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";
$headers .= 'From:  ' . $fromName . ' <' . $fromEmail .'>' . " \r\n" .
            'Reply-To: '.  $fromEmail . "\r\n" .
            'X-Mailer: PHP/' . phpversion();

The \r\n should be in double quotes(") itself, the single quotes(') will not work.

This applies to all languages:

You want to have an event/listener model. You create a listener to wait for a particular event. The event would be created (or signaled) in your worker thread. This will block the thread until the signal is received instead of constantly polling to see if a condition is met, like the solution you currently have.

Your situation is one of the most common causes for deadlocks- make sure you signal the other thread regardless of errors that may have occurred. Example- if your application throws an exception- and never calls the method to signal the other that things have completed. This will make it so the other thread never 'wakes up'.

I suggest that you look into the concepts of using events and event handlers to better understand this paradigm before implementing your case.

Alternatively you can use a blocking function call using a mutex- which will cause the thread to wait for the resource to be free. To do this you need good thread synchronization- such as:

Thread-A Locks lock-a
Run thread-B
Thread-B waits for lock-a
Thread-A unlocks lock-a (causing Thread-B to continue)
Thread-A waits for lock-b 
Thread-B completes and unlocks lock-b

webRequest.ContentType = "application/x-www-form-urlencoded";

1. Where does application/x-www-form-urlencoded's name come from?

   If you send HTTP GET request, you can use query parameters as follows:

   http://example.com/path/to/page?name=ferret&color=purple

   The content of the fields is encoded as a query string. The application/x-www-form- urlencoded's name come from the previous url query parameter but the query parameters is in where the body of request instead of url.

   The whole form data is sent as a long query string.The query string contains name- value pairs separated by & character

   e.g. field1=value1&field2=value2

2. It can be simple request called simple - don't trigger a preflight check

   Simple request must have some properties. You can look here for more info. One of them is that there are only three values allowed for Content-Type header for simple requests

   • application/x-www-form-urlencoded
   • multipart/form-data
   • text/plain

3.For mostly flat param trees, application/x-www-form-urlencoded is tried and tested.

request.ContentType = "application/json; charset=utf-8";

1. The data will be json format.

axios and superagent, two of the more popular npm HTTP libraries, work with JSON bodies by default.

{
  "id": 1,
  "name": "Foo",
  "price": 123,
  "tags": [
    "Bar",
    "Eek"
  ],
  "stock": {
    "warehouse": 300,
    "retail": 20
  }
}

2. "application/json" Content-Type is one of the Preflighted requests.

Now, if the request isn't simple request, the browser automatically sends a HTTP request before the original one by OPTIONS method to check whether it is safe to send the original request. If itis ok, Then send actual request. You can look here for more info.

3. application/json is beginner-friendly. URL encoded arrays can be a nightmare!

What about:

<input type="button" style="width:24px;" value="A"/>

If you mean to change default directory for "Node.js command prompt", when you launch it, then (Windows case)

1. go the directory where NodeJS was installed
2. find file nodevars.bat
3. open it with editor as administrator

4. change the default path in the row which looks like

   if "%CD%\"=="%~dp0" cd /d "%HOMEDRIVE%%HOMEPATH%"
   

with your path. It could be for example

    if "%CD%\"=="%~dp0" cd /d "c://MyDirectory/"

if you mean to change directory once when you launched "Node.js command prompt", then execute the following command in the Node.js command prompt:

     cd c:/MyDirectory/

From the proxy_pass documentation:

A special case is using variables in the proxy_pass statement: The requested URL is not used and you are fully responsible to construct the target URL yourself.

Since you're using $1 in the target, nginx relies on you to tell it exactly what to pass. You can fix this in two ways. First, stripping the beginning of the uri with a proxy_pass is trivial:

location /service/ {
  # Note the trailing slash on the proxy_pass.
  # It tells nginx to replace /service/ with / when passing the request.
  proxy_pass http://apache/;
}

Or if you want to use the regex location, just include the args:

location ~* ^/service/(.*) {
  proxy_pass http://apache/$1$is_args$args;
}

Client use convert File to ToBase64String, after use Xml to promulgate to Server call, this server use File.WriteAllBytes(path,Convert.FromBase64String(dataFile_Client_sent)).

Good lucky!

I recommend checking out docker-compose. Here's how that would work:

Create a file named, docker-compose.yml that looks like this:

version: '2'

services:

  mysql:
    image: mariadb:10.1.19
    ports:
      - 8083:3306
    volumes:
      - ./mysql:/var/lib/mysql
    environment:
      MYSQL_ROOT_PASSWORD: wp

Next, run:

$ docker-compose up

Notes:

• For latest mariadb image tag see https://hub.docker.com/_/mariadb/

Now, you can access the mysql console thusly:

$ mysql -P 8083 --protocol=tcp -u root -p

Enter password:
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 8

Notes:

• You can pass the -d flag to run the mysql/mariadb container in detached/background mode.

• The password is "wp" which is defined in the docker-compose.yml file.

• Same advice as maniekq but full example with docker-compose.

There is a solution:

<resources>
    <item name="text_line_spacing" format="float" type="dimen">1.0</item>
</resources>

In this way, your float number will be under @dimen. Notice that you can use other "format" and/or "type" modifiers, where format stands for:

Format = enclosing data type:

• float
• boolean
• fraction
• integer
• ...

and type stands for:

Type = resource type (referenced with R.XXXXX.name):

• color
• dimen
• string
• style
• etc...

To fetch resource from code, you should use this snippet:

TypedValue outValue = new TypedValue();
getResources().getValue(R.dimen.text_line_spacing, outValue, true);
float value = outValue.getFloat();  

I know that this is confusing (you'd expect call like getResources().getDimension(R.dimen.text_line_spacing)), but Android dimensions have special treatment and pure "float" number is not valid dimension.

Additionally, there is small "hack" to put float number into dimension, but be WARNED that this is really hack, and you are risking chance to lose float range and precision.

<resources>
    <dimen name="text_line_spacing">2.025px</dimen>
</resources>

and from code, you can get that float by

float lineSpacing = getResources().getDimension(R.dimen.text_line_spacing);

in this case, value of lineSpacing is 2.024993896484375, and not 2.025 as you would expected.

simply modify your home with the command: usermod -d /newhome username

Use this way:

var d = new Date();
localtime = d.toLocaleTimeString('en-US', { hour12: false });

Result: 18:56:31

If U want to delete more than one characters, say comma and dots you can write

<script type="text/javascript">
  var mystring = "It,is,a,test.string,of.mine" 
  mystring = mystring.replace(/[,.]/g , ''); 
  alert( mystring);
</script>

Since TypeScript is a typed superset of ES6 JavaScript. And lodash are a library of javascript.

Using lodash to checks if value is null or undefined can be done using _.isNil().

_.isNil(value)

Arguments

value (*): The value to check.

Returns

(boolean): Returns true if value is nullish, else false.

Example

_.isNil(null);
// => true

_.isNil(void 0);
// => true

_.isNil(NaN);
// => false

SortedDictionary<string, int> userCache = new SortedDictionary<string, int>
{
  {"a", 1},
  {"b", 2},
  {"c", 3}
};
comboBox1.DataSource = new BindingSource(userCache, null);
comboBox1.DisplayMember = "Key";
comboBox1.ValueMember = "Value";

But why are you setting the ValueMember to "Value", shouldn't it be bound to "Key" (and DisplayMember to "Value" as well)?

On some devices (for example samsung galaxy sII )internal memory card mabe be in vfat. In this case use refer last code, we obtain path internal memory card (/mnt/sdcad) but no external card. Code refer below solve this problem.

In my case, I was using simple impersonation and the impersonation user had trouble accessing one of the project assemblies. My solution:

1. Look for the message of the inner exception to identify the problematic assembly.

2. Modify the security properties of the assembly file.

   a) Add the user account you're using for impersonation to the Group and user names.

   b) Give that user account full access to the assembly file.

This is a big topic. The Spring reference doc devotes multiple chapters to it. I recommend reading the ones on Aspect-Oriented Programming and Transactions, as Spring's declarative transaction support uses AOP at its foundation.

But at a very high level, Spring creates proxies for classes that declare @Transactional on the class itself or on members. The proxy is mostly invisible at runtime. It provides a way for Spring to inject behaviors before, after, or around method calls into the object being proxied. Transaction management is just one example of the behaviors that can be hooked in. Security checks are another. And you can provide your own, too, for things like logging. So when you annotate a method with @Transactional, Spring dynamically creates a proxy that implements the same interface(s) as the class you're annotating. And when clients make calls into your object, the calls are intercepted and the behaviors injected via the proxy mechanism.

Transactions in EJB work similarly, by the way.

As you observed, through, the proxy mechanism only works when calls come in from some external object. When you make an internal call within the object, you're really making a call through the "this" reference, which bypasses the proxy. There are ways of working around that problem, however. I explain one approach in this forum post in which I use a BeanFactoryPostProcessor to inject an instance of the proxy into "self-referencing" classes at runtime. I save this reference to a member variable called "me". Then if I need to make internal calls that require a change in the transaction status of the thread, I direct the call through the proxy (e.g. "me.someMethod()".) The forum post explains in more detail. Note that the BeanFactoryPostProcessor code would be a little different now, as it was written back in the Spring 1.x timeframe. But hopefully it gives you an idea. I have an updated version that I could probably make available.

My favorite smtp server is hMailServer.

It has a nice windows friendly installer and wizard. Hands down the easiest mail server I've ever setup.

It can proxy through your gmail/yahoo/etc account or send email directly.

Once it is installed, email in xampp just works with no config changes.

Use

print " ".join("0x%s"%my_string[i:i+2] for i in range(0, len(my_string), 2))

like this:

>>> my_string = "deadbeef"
>>> print " ".join("0x%s"%my_string[i:i+2] for i in range(0, len(my_string), 2))
0xde 0xad 0xbe 0xef
>>>

On an unrelated side note ... using string as a variable name even as an example variable name is very bad practice.

The closest you'll get is :active:

#btnLeft:active {
    width: 70px;
    height: 74px;
}

However this will only apply the style when the mouse button is held down. The only way to apply a style and keep it applied onclick is to use a bit of JavaScript.

If SET time_zone or SET GLOBAL time_zone does not work, you can change as below:

• Change timezone system, example: ubuntu... $ sudo dpkg-reconfigure tzdata

• Restart the server or you can restart apache2 and mysql (/etc/init.d/mysql restart)

A quick and easy way for Mac OS X 10.8 (Mountain Lion), 10.9 (Mavericks), 10.10 (Yosemite), and 10.11 (El Capitan):

I assume you have XCode, its command line tools, Python, and MySQL installed.

1. Install PIP:

   sudo easy_install pip
   

2. Edit ~/.profile: (Might not be necessary in Mac OS X 10.10)

   nano ~/.profile
   

   Copy and paste the following two line

   export PATH=/usr/local/mysql/bin:$PATH
   export DYLD_LIBRARY_PATH=/usr/local/mysql/lib/
   

   Save and exit. Afterwords execute the following command:

   source  ~/.profile
   

3. Install MySQLdb

   sudo pip install MySQL-python
   

   To test if everything works fine just try

   python -c "import MySQLdb"
   

It worked like a charm for me. I hope it helps.

If you encounter an error regarding a missing library: Library not loaded: libmysqlclient.18.dylib then you have to symlink it to /usr/lib like so:

sudo ln -s /usr/local/mysql/lib/libmysqlclient.18.dylib /usr/lib/libmysqlclient.18.dylib

I can see only 1 things happening here: You did't set properly dependences to thelibrary.lib in your project meaning that thelibrary.lib is built in the wrong order (Or in the same time if you have more then 1 CPU build configuration, which can also explain randomness of the error). ( You can change the project dependences in: Menu->Project->Project Dependencies )

There is no easy way to animate hiding/showing views. You can try method described in following answer: How do I animate View.setVisibility(GONE)

What makes jQuery easy to use is that you don't have to apply attributes to each element. The jQuery object contains an array of elements, and the methods of the jQuery object applies the same attributes to all the elements in the array.

There is also a shorter form for $(document).ready(function(){...}) in $(function(){...}).

So, this is all you need:

$(function(){
  $('div.easy_editor').css('border','9px solid red');
});

If you want the code to work for any element with that class, you can just specify the class in the selector without the tag name:

$(function(){
  $('.easy_editor').css('border','9px solid red');
});

I just found out about the get_html_translation_table function. You pass it HTML_ENTITIES or HTML_SPECIALCHARS and it returns an array with the characters that will be encoded and how they will be encoded.

Why is the WebSockets protocol better?

I don't think we can compare them side by side like who is better. That won't be a fair comparison simply because they are solving two different problems. Their requirements are different. It will be like comparing apples to oranges. They are different.

HTTP is a request-response protocol. The client (browser) wants something, the server gives it. That is. If the data client wants is big, the server might send streaming data to void unwanted buffer problems. Here the main requirement or problem is how to make the request from clients and how to response the resources(hypertext) they request. That is where HTTP shine.

In HTTP, only client requests. The server only responds.

WebSocket is not a request-response protocol where only the client can request. It is a socket(very similar to TCP socket). Mean once the connection is open, either side can send data until the underlining TCP connection is closed. It is just like a normal socket. The only difference with TCP socket is WebSocket can be used on the web. On the web, we have many restrictions on a normal socket. Most firewalls will block other ports than 80 and 433 that HTTP used. Proxies and intermediaries will be problematic as well. So to make the protocol easier to deploy to existing infrastructures WebSocket use HTTP handshake to upgrade. That means when the first time connection is going to open, the client sent an HTTP request to tell the server saying "That is not HTTP request, please upgrade to WebSocket protocol".

Upgrade: websocket
Connection: Upgrade
Sec-WebSocket-Key: x3JJHMbDL1EzLkh9GBhXDw==
Sec-WebSocket-Protocol: chat, superchat
Sec-WebSocket-Version: 13

Once the server understands the request and upgraded to WebSocket protocol, none of the HTTP protocols applied anymore.

So my answer is Neither one is better than each other. They are completely different.

Why was it implemented instead of updating the HTTP protocol?

Well, we can make everything under the name called HTTP as well. But shall we? If they are two different things, I will prefer two different names. So do Hickson and Michael Carter .

From the Intel's manual - Instruction Set Reference, the JE and JZ have the same opcode (74 for rel8 / 0F 84 for rel 16/32) also JNE and JNZ (75 for rel8 / 0F 85 for rel 16/32) share opcodes.

JE and JZ they both check for the ZF (or zero flag), although the manual differs slightly in the descriptions of the first JE rel8 and JZ rel8 ZF usage, but basically they are the same.

Here is an extract from the manual's pages 464, 465 and 467.

 Op Code    | mnemonic  | Description
 -----------|-----------|-----------------------------------------------  
 74 cb      | JE rel8   | Jump short if equal (ZF=1).
 74 cb      | JZ rel8   | Jump short if zero (ZF ? 1).

 0F 84 cw   | JE rel16  | Jump near if equal (ZF=1). Not supported in 64-bit mode.
 0F 84 cw   | JZ rel16  | Jump near if 0 (ZF=1). Not supported in 64-bit mode.

 0F 84 cd   | JE rel32  | Jump near if equal (ZF=1).
 0F 84 cd   | JZ rel32  | Jump near if 0 (ZF=1).

 75 cb      | JNE rel8  | Jump short if not equal (ZF=0).
 75 cb      | JNZ rel8  | Jump short if not zero (ZF=0).

 0F 85 cd   | JNE rel32 | Jump near if not equal (ZF=0).
 0F 85 cd   | JNZ rel32 | Jump near if not zero (ZF=0).

My solution is to use the difference in the the column values length compared the same column length but with the double quotes replaced with spaces and trimmed in order to calculate the start and length values as parameters in a SUBSTRING function.

The advantage of doing it this way is that you can remove any leading or trailing character even if it occurs multiple times whilst leaving any characters that are contained within the text.

Here is my answer with some test data:

 SELECT 
  x AS before
  ,SUBSTRING(x 
       ,LEN(x) - (LEN(LTRIM(REPLACE(x, '"', ' ')) + '|') - 1) + 1 --start_pos
       ,LEN(LTRIM(REPLACE(x, '"', ' '))) --length
       ) AS after
FROM 
(
SELECT 'test'     AS x UNION ALL
SELECT '"'        AS x UNION ALL
SELECT '"test'    AS x UNION ALL
SELECT 'test"'    AS x UNION ALL
SELECT '"test"'   AS x UNION ALL
SELECT '""test'   AS x UNION ALL
SELECT 'test""'   AS x UNION ALL
SELECT '""test""' AS x UNION ALL
SELECT '"te"st"'  AS x UNION ALL
SELECT 'te"st'    AS x
) a

Which produces the following results:

before  after
-----------------
test    test
"   
"test   test
test"   test
"test"  test
""test  test
test""  test
""test""    test
"te"st" te"st
te"st   te"st

One thing to note that when getting the length I only need to use LTRIM and not LTRIM and RTRIM combined, this is because the LEN function does not count trailing spaces.

You can remove the diacritics from alphabets by using:

var str = "résumé"
str.normalize('NFD').replace(/[\u0300-\u036f]/g, '') // returns resume

It will remove all the diacritical marks, and then perform your regex on it

Reference:

I think thats not the reason everybody told above. There is something wrong in your code, maybe miss spelling or mismatching with the database column names. If mysqli query gets no result then it will return false, so that it is not a object - is a wrong idea. Everything works fine. it returns 1 or 0 if query have result or not.

So, my suggestion is check your variable names and table column names or any other misspelling.

The solution 7 does not give the correct result in the case there's just one word. You should not just count the elements in gregexpr's result (which is -1 if there where not matches) but count the elements > 0.

Ergo:

sapply(gregexpr("\\W+", str1), function(x) sum(x>0) ) + 1 

If you're trying to connect using "SQL Server Authentication" then you may want to modify your server authentication:

Within the Microsoft SQL Server Management Studio in the object explorer:

1. Right click on the server and click Properties

2. Go to the Security page

3. Under Server authentication choose the SQL Server and Windows Authentication mode radio button

4. Click OK

5. Restart SQL Services

Just for the records, Java 8 provides a better alternative.

int[][] table = new int[][]{{2,4,5},{6,34,7},{23,57,2}};

System.out.println(Stream.of(table)
    .map(rowParts -> Stream.of(rowParts
    .map(element -> ((Integer)element).toString())
        .collect(Collectors.joining("\t")))
    .collect(Collectors.joining("\n")));

I've just found a great way of doing that. In my example I'm using a RichTextBox but it should work with any Control:

public class DisabledRichTextBox : System.Windows.Forms.RichTextBox
{
    // See: http://wiki.winehq.org/List_Of_Windows_Messages

    private const int WM_SETFOCUS   = 0x07;
    private const int WM_ENABLE     = 0x0A;
    private const int WM_SETCURSOR  = 0x20;

    protected override void WndProc(ref System.Windows.Forms.Message m)
    {
        if (!(m.Msg == WM_SETFOCUS || m.Msg == WM_ENABLE || m.Msg == WM_SETCURSOR))
            base.WndProc(ref m);
    }
}

You can safely set Enabled = true and ReadOnly = false, and it will act like a label, preventing focus, user input, cursor change, without being actually disabled.

See if it works for you. Greetings

If you just want to get the information of current directory, you can type:

pwd

and you don't need to use the Nautilus, or you can use a teamviewer software to remote connect to the computer, you can get everything you want.

As previous answers didn't work well (it was good, but not enough) for me on a 14.04 Ubuntu Server, I mention these recommendations (this is a quote).

Edit: note that as @jason-faust mentioned it in the comments, on 14.04, the authbind package that ships with it does support IPv6 now, so the prefer IPv4 thing isn't needed any longer.

1) Install authbind
2) Make port 80 available to authbind (you need to be root):

  touch /etc/authbind/byport/80
  chmod 500 /etc/authbind/byport/80
  chown tomcat7 /etc/authbind/byport/80

3) Make IPv4 the default (authbind does not currently support IPv6).
   To do so, create the file TOMCAT/bin/setenv.sh with the following content: 

   CATALINA_OPTS="-Djava.net.preferIPv4Stack=true"

4) Change /usr/share/tomcat7/bin/startup.sh

  exec authbind --deep "$PRGDIR"/"$EXECUTABLE" start "$@"
  # OLD: exec "$PRGDIR"/"$EXECUTABLE" start "$@"

If you already got a setenv.sh file in /usr/share/tomcat7/bin with CATALINA_OPTS, you have to use :

export CATALINA_OPTS="$CATALINA_OPTS -Djava.net.preferIPv4Stack=true"

Now you can change the port to 80 as told in other answers.

You may get this error when your log4j.properties are not present in the classpath.

This means you have to move the log4j.properties into the src folder and set the output to the bin folder so that at run time log4j.properties will read from the bin folder and your error will be resolved easily.

The answer provided by the OP is not the best. It is inefficient, as it creates a new List and an unnecessary new array. Also, it raises "unchecked" warnings because of the type safety issues around generic arrays.

Instead, use something like this:

public static
<T extends Comparable<? super T>> List<T> asSortedList(Collection<T> c) {
  List<T> list = new ArrayList<T>(c);
  java.util.Collections.sort(list);
  return list;
}

Here's a usage example:

Map<Integer, String> map = new HashMap<Integer, String>();
/* Add entries to the map. */
...
/* Now get a sorted list of the *values* in the map. */
Collection<String> unsorted = map.values();
List<String> sorted = Util.asSortedList(unsorted);

Just try this in razor

@{
    var selectList = new SelectList(
        new List<SelectListItem>
        {
            new SelectListItem {Text = "Google", Value = "Google"},
            new SelectListItem {Text = "Other", Value = "Other"},
        }, "Value", "Text");
}

and then

@Html.DropDownListFor(m => m.YourFieldName, selectList, "Default label", new { @class = "css-class" })

or

@Html.DropDownList("ddlDropDownList", selectList, "Default label", new { @class = "css-class" })

Well, I think nginx by itself doesn't have that in its setup, because the Ubuntu-maintained package does it as a convention to imitate Debian's apache setup. You could create it yourself if you wanted to emulate the same setup.

Create /etc/nginx/sites-available and /etc/nginx/sites-enabled and then edit the http block inside /etc/nginx/nginx.conf and add this line

include /etc/nginx/sites-enabled/*;

Of course, all the files will be inside sites-available, and you'd create a symlink for them inside sites-enabled for those you want enabled.

If you want to get unix timestamp, then you need to use:

timestamp=$(date +%s)

%T will give you just the time; same as %H:%M:%S (via http://www.cyberciti.biz/faq/linux-unix-formatting-dates-for-display/)

TO ADD: @Christopher's answer does not work on API 7/8 (as per @Jonny's correct comment) IF you are using colours, instead of drawables. (In my testing, using drawables as per Christopher works fine)

Here is the FIX for 2.3 and below when using colours:

• Android: Entire ListView changes color on focus, not just ListView child item

As per @Charles Harley, there is a bug in 2.3 and below where filling the list item with a colour causes the colour to flow out over the whole list. His fix is to define a shape drawable containing the colour you want, and to use that instead of the colour.

I suggest looking at this link if you want to just use a colour as selector, and are targeting Android 2 (or at least allow for Android 2).

If you want it visually formatted to two decimals as a string (for output) use toFixed():

var priceString = someValue.toFixed(2);

The answer by @David has two problems:

1. It leaves the result as a floating point number, and consequently holds the possibility of displaying a particular result with many decimal places, e.g. 134.1999999999 instead of "134.20".

2. If your value is an integer or rounds to one tenth, you will not see the additional decimal value:

   var n = 1.099;
   (Math.round( n * 100 )/100 ).toString() //-> "1.1"
   n.toFixed(2)                            //-> "1.10"
   
   var n = 3;
   (Math.round( n * 100 )/100 ).toString() //-> "3"
   n.toFixed(2)                            //-> "3.00"
   

And, as you can see above, using toFixed() is also far easier to type. ;)

The statement from Microsoft regarding the end of Internet Explorer 11 support mentions that it will continue to receive security updates, compatibility fixes, and technical support until its end of life. The wording of this statement leads me to believe that Microsoft has no plans to continue adding features to Internet Explorer 11, and instead will be focusing on Edge.

If you require ES6 features in Internet Explorer 11, check out a transpiler such as Babel.

You can use sort.Slice() plus sort.Search()

type Person struct {
    Name string
}

func main() {
    crowd := []Person{{"Zoey"}, {"Anna"}, {"Benni"}, {"Chris"}}

    sort.Slice(crowd, func(i, j int) bool {
        return crowd[i].Name <= crowd[j].Name
    })

    needle := "Benni"
    idx := sort.Search(len(crowd), func(i int) bool {
        return string(crowd[i].Name) >= needle
    })

    if crowd[idx].Name == needle {
        fmt.Println("Found:", idx, crowd[idx])
    } else {
        fmt.Println("Found noting: ", idx)
    }
}

The best way I have found to manage keyboard input on a Windows Forms form is to process it after the keystroke and before the focused control receives the event. Microsoft maintains a built-in Form-level property named .KeyPreview to facilitate this precise thing:

public frmForm()
{
    // ...
    frmForm.KeyPreview = true;
    // ...
}

Then the form's _KeyDown, _KeyPress, and / or _KeyUp events can be marshaled to access input events before the focused form control ever sees them, and you can apply handler logic to capture the event there or allow it to pass through to the focused form control.

Although not as structurally graceful as XAML's event-routing architecture, it makes management of form-level functions in Winforms far simpler. See the MSDN notes on KeyPreview for caveats.

For me, only this solution worked for multiline text:

.circle-multiline {
    display: table-cell;
    height: 200px;
    width: 200px;
    text-align: center;
    vertical-align: middle;
    border-radius: 50%;
    background: yellow;
}

It looks like ng-attr is a new directive in AngularJS 1.1.4 that you can possibly use in this case.

<!-- example -->
<a ng-attr-title="{{product.shortDesc}}"></a>

However, if you stay with 1.0.7, you can probably write a custom directive to mirror the effect.

For Windows. Run these commands in Git Bash:

git config --global diff.tool meld
git config --global difftool.meld.path "C:\Program Files (x86)\Meld\Meld.exe"
git config --global difftool.prompt false

git config --global merge.tool meld
git config --global mergetool.meld.path "C:\Program Files (x86)\Meld\Meld.exe"
git config --global mergetool.prompt false

(Update the file path for Meld.exe if yours is different.)

For Linux. Run these commands in Git Bash:

git config --global diff.tool meld
git config --global difftool.meld.path "/usr/bin/meld"
git config --global difftool.prompt false

git config --global merge.tool meld
git config --global mergetool.meld.path "/usr/bin/meld"
git config --global mergetool.prompt false

You can verify Meld's path using this command:

which meld

The solution work on my cases and cross-browser:

var getKeys = function(obj) {
    var type = typeof  obj;
    var isObjectType = type === 'function' || type === 'object' || !!obj;

    // 1
    if(isObjectType) {
        return Object.keys(obj);
    }

    // 2
    var keys = [];
    for(var i in obj) {
        if(obj.hasOwnProperty(i)) {
            keys.push(i)
        }
    }
    if(keys.length) {
        return keys;
    }

    // 3 - bug for ie9 <
    var hasEnumbug = !{toString: null}.propertyIsEnumerable('toString');
    if(hasEnumbug) {
        var nonEnumerableProps = ['valueOf', 'isPrototypeOf', 'toString',
            'propertyIsEnumerable', 'hasOwnProperty', 'toLocaleString'];

        var nonEnumIdx = nonEnumerableProps.length;

        while (nonEnumIdx--) {
            var prop = nonEnumerableProps[nonEnumIdx];
            if (Object.prototype.hasOwnProperty.call(obj, prop)) {
                keys.push(prop);
            }
        }

    }

    return keys;
};

The simplest way to find the framework version of the current .NET project is:

1. Right-click on the project and go to "Properties."
2. In the first tab, "Application," you can see the target framework this project is using.

If you want to completely remove commits from history, you can also do a dump of the repo at a specific revision, then import that dump. Specifically:

svnrdump dump -r 1:<rev> <url> > filename.dump

The svnrdump command performs the same function as svnadmin dump but works on a remote repo.

Next just import the dump file into your repo of choice. This was tested to worked well on Beanstalk.

Converting SecretKeySpec to String and vice-versa: you can use getEncoded() method in SecretKeySpec which will give byteArray, from that you can use encodeToString() to get string value of SecretKeySpec in Base64 object.

While converting SecretKeySpec to String: use decode() in Base64 will give byteArray, from that you can create instance for SecretKeySpec with the params as the byteArray to reproduce your SecretKeySpec.

String mAesKey_string;
SecretKeySpec mAesKey= new SecretKeySpec(secretKey.getEncoded(), "AES");

//SecretKeySpec to String 
    byte[] byteaes=mAesKey.getEncoded();
    mAesKey_string=Base64.encodeToString(byteaes,Base64.NO_WRAP);

//String to SecretKeySpec
    byte[] aesByte = Base64.decode(mAesKey_string, Base64.NO_WRAP);
    mAesKey= new SecretKeySpec(aesByte, "AES");

you can try:

services:
  nameis:
    container_name: hi_my
    build: .
    image: hi_my_nameis:v1.0.0

In most circumstances, I recommend using the <object> tag to display SVG images. It feels a little unnatural, but it's the most reliable method if you want to provide dynamic effects.

For images without interaction, the <img> tag or a CSS background can be used.

Inline SVGs or iframes are possible options for some projects, but it's best to avoid <embed>

But if you want to play with SVG stuff like

• Changing colors
• Resize path
• rotate svg

Go with the embedded one

<svg>
    <g> 
        <path> </path>
    </g>
</svg>

Had similar problem, was looking for white spaces in a string, solution:

• To search for 1 space:

  var regex = /^.+\s.+$/ ;
  

  example: "user last_name"

• To search for multiple spaces:

  var regex = /^.+\s.+$/g ;
  

  example: "user last name"

For multiline TextView you should use android.text.style.CharacterStyle like this:

SpannableString spannable = new SpannableString(text);
spannable.setSpan(new StrikethroughSpan(), 0, text.length(), Spanned.SPAN_INCLUSIVE_EXCLUSIVE);
remoteViews.setTextViewText(R.id.itemText, spannable);

Many ways this can be achieved.

Simple approach should be taking Substring of an input string.

var result = input.Substring(input.Length - 3);

Another approach using Regular Expression to extract last 3 characters.

var result = Regex.Match(input,@"(.{3})\s*$");

Microsoft provides us built-in functionality which we use in our application for security purposes, so no one can hack our site or invade some critical information.

From Purpose Of ValidateAntiForgeryToken In MVC Application by Harpreet Singh:

Use of ValidateAntiForgeryToken

Let’s try with a simple example to understand this concept. I do not want to make it too complicated, that’s why I am going to use a template of an MVC application, already available in Visual Studio. We will do this step by step. Let’s start.

1. Step 1 - Create two MVC applications with default internet template and give those names as CrossSite_RequestForgery and Attack_Application respectively.

2. Now, open CrossSite_RequestForgery application's Web Config and change the connection string with the one given below and then save.

`

<connectionStrings> <add name="DefaultConnection" connectionString="Data Source=local\SQLEXPRESS;Initial Catalog=CSRF;
Integrated Security=true;" providerName="System.Data.SqlClient" /> 
 </connectionStrings>

3. Now, click on Tools >> NuGet Package Manager, then Package Manager Console

4. Now, run the below mentioned three commands in Package Manager Console to create the database.

Enable-Migrations add-migration first update-database

Important Notes - I have created database with code first approach because I want to make this example in the way developers work. You can create database manually also. It's your choice.

5. Now, open Account Controller. Here, you will see a register method whose type is post. Above this method, there should be an attribute available as [ValidateAntiForgeryToken]. Comment this attribute. Now, right click on register and click go to View. There again, you will find an html helper as @Html.AntiForgeryToken() . Comment this one also. Run the application and click on register button. The URL will be open as:

http://localhost:52269/Account/Register

Notes- I know now the question being raised in all readers’ minds is why these two helpers need to be commented, as everyone knows these are used to validate request. Then, I just want to let you all know that this is just because I want to show the difference after and before applying these helpers.

6. Now, open the second application which is Attack_Application. Then, open Register method of Account Controller. Just change the POST method with the simple one, shown below.

   Registration Form
   1. @Html.LabelFor(m => m.UserName) @Html.TextBoxFor(m => m.UserName)
   2. @Html.LabelFor(m => m.Password) @Html.PasswordFor(m => m.Password)
   3. @Html.LabelFor(m => m.ConfirmPassword) @Html.PasswordFor(m => m.ConfirmPassword)

7.Now, suppose you are a hacker and you know the URL from where you can register user in CrossSite_RequestForgery application. Now, you created a Forgery site as Attacker_Application and just put the same URL in post method.

8.Run this application now and fill the register fields and click on register. You will see you are registered in CrossSite_RequestForgery application. If you check the database of CrossSite_RequestForgery application then you will see and entry you have entered.

9. Important - Now, open CrossSite_RequestForgery application and comment out the token in Account Controller and register the View. Try to register again with the same process. Then, an error will occur as below.

Server Error in '/' Application. ________________________________________ The required anti-forgery cookie "__RequestVerificationToken" is not present.

This is what the concept says. What we add in View i.e. @Html.AntiForgeryToken() generates __RequestVerificationToken on load time and [ValidateAntiForgeryToken] available on Controller method. Match this token on post time. If token is the same, then it means this is a valid request.

UPDATE Sep 29 2016 for Angular 2.0 Final & VS 2015

The workaround is no longer needed, to fix you just need to install TypeScript version 2.0.3.

Fix taken from the edit on this github issue comment.

Maybe this is a bit redundant, but no one appeared to have mentioned this as a solution.

As a beginner in SQL I find that when using a BEGIN and END SSMS usually adds a squiggly line with incorrect syntax near 'END' to END, simply because there's no content in between yet. If you're just setting up BEGIN and END to get started and add the actual query later, then simply add a bogus PRINT statement so SSMS stops bothering you.

For example:

IF (1=1)
BEGIN
  PRINT 'BOGUS'
END

The following will indeed set you on the wrong track, thinking you made a syntax error which in this case just means you still need to add content in between BEGIN and END:

IF (1=1)
BEGIN
END

As for renaming tables:

    protected override void Up(MigrationBuilder migrationBuilder)
    {
        migrationBuilder.RenameTable(name: "OldTableName", schema: "dbo", newName: "NewTableName", newSchema: "dbo");
    }

    protected override void Down(MigrationBuilder migrationBuilder)
    {
        migrationBuilder.RenameTable(name: "NewTableName", schema: "dbo", newName: "OldTableName", newSchema: "dbo");
    }

As for renaming columns:

    protected override void Up(MigrationBuilder migrationBuilder)
    {
        migrationBuilder.RenameColumn(name: "OldColumnName", table: "TableName", newName: "NewColumnName", schema: "dbo");
    }

    protected override void Down(MigrationBuilder migrationBuilder)
    {
        migrationBuilder.RenameColumn(name: "NewColumnName", table: "TableName", newName: "OldColumnName", schema: "dbo");
    }

I also faced the same problem. Then I found a solution after a lot of searching .

The problem was that when we get the datetime object from model or form it is offset aware and if we get the time by system it is offset naive.

So what I did is I got the current time using timezone.now() and import the timezone by from django.utils import timezone and put the USE_TZ = True in your project settings file.

<create-report-card-form [currentReportCardCount]="providerData.reportCards.length" ...
                         ^^^^^^^^^^^^^^^^^^^^^^^^

In your HomeComponent template, you are trying to bind to an input on the CreateReportCardForm component that doesn't exist.

In CreateReportCardForm, these are your only three inputs:

@Input() public reportCardDataSourcesItems: SelectItem[];
@Input() public reportCardYearItems: SelectItem[];
@Input() errorMessages: Message[];

Add one for currentReportCardCount and you should be good to go.

For a project this size, you should stop writing pure JavaScript and turn to some of the libraries available. I'd recommend jQuery (http://jquery.com/), which allows you to select elements by css-selectors, which I recon should speed up your development quite a bit.

Example of your code then becomes;

function AddtoCart() {
  var len = $("#Items tr").length, $row, $inp1, $inp2, $cells;

  $row = $("#Items td:first").clone(true);
  $cells = $row.find("td");

  $cells.get(0).html( len );

  $inp1 = $cells.get(1).find("input:first");
  $inp1.attr("id", $inp1.attr("id") + len).val("");

  $inp2 = $cells.get(2).find("input:first");
  $inp2.attr("id", $inp2.attr("id") + len).val("");

  $("#Items").append($row);
    }

I can see that you might not understand that code yet, but take a look at jQuery, it's easy to learn and will make this development way faster.

I would use the libraries already created specifically for js shopping carts if I were you though.

To your problem; If i look at your jsFiddle, it doesn't even seem like you have defined a table with the id Items? Maybe that's why it doesn't work?

Are you looking for

It wasn't very clear from the description. But may be this is what you are looking for http://en.wikipedia.org/wiki/Help:Displaying_a_formula#Continuation_and_cases

CREATE VIEW EmployeeWithManager AS 
SELECT e.[emp id], e.[emp name], m.[emp id], m.[emp name] 
FROM Employee e LEFT JOIN Employee m ON e.[emp mgr id] = m.[emp id]

This definition uses a left outer join which means that even employees whose manager ID is NULL, or whose manager has been deleted (if your application allows that) will be listed, with their manager's attributes returned as NULL.

If you used an inner join instead, only people who have managers would be listed.

Issue is with remote server, can you login to the remote server and check if "scp" works

probable causes: - scp is not in path - openssh client not installed correctly

for more details http://www.linuxquestions.org/questions/linux-newbie-8/bash-scp-command-not-found-920513/

Try this

int sum = 0;
foreach (DataRow dr in dt.Rows)
{
     dynamic value = dr[index].ToString();
     if (!string.IsNullOrEmpty(value))
     { 
         sum += Convert.ToInt32(value);
     }
}

As @Bradford20000 pointed out in the comments, there might be a gradle.properties file as well as global gradle scripts located under $HOME/.gradle. In such case special attention must be paid when deleting the content of this directory.

The .gradle/caches directory holds the Gradle build cache. So if you have any error about build cache, you can delete it.

The --no-build-cache option will run gradle without the build cache.

Just to be sure that this is really the "conversion" you need, please note that jks files are keystores, a file format used to store more than one certificate and allows you to retrieve them programmatically using the Java security API, it's not a one-to-one conversion between equivalent formats.

So, if you just want to import that certificate in a new ad-hoc keystore you can do it with Keystore Explorer, a graphical tool. You'll be able to modify the keystore and the certificates contained therein like you would have done with the java terminal utilities like keytool (but in a more accessible way).

It looks like you want to define Truck as a Class with properties NumberOfAxles, AxleWeights & AxleSpacings.

This can be defined in a CLASS MODULE (here named clsTrucks)

Option Explicit

Private tID As String
Private tNumberOfAxles As Double
Private tAxleSpacings As Double


Public Property Get truckID() As String
    truckID = tID
End Property

Public Property Let truckID(value As String)
    tID = value
End Property

Public Property Get truckNumberOfAxles() As Double
    truckNumberOfAxles = tNumberOfAxles
End Property

Public Property Let truckNumberOfAxles(value As Double)
    tNumberOfAxles = value
End Property

Public Property Get truckAxleSpacings() As Double
    truckAxleSpacings = tAxleSpacings
End Property

Public Property Let truckAxleSpacings(value As Double)
    tAxleSpacings = value
End Property

then in a MODULE the following defines a new truck and it's properties and adds it to a collection of trucks and then retrieves the collection.

Option Explicit

Public TruckCollection As New Collection

Sub DefineNewTruck()
Dim tempTruck As clsTrucks
Dim i As Long

    'Add 5 trucks
    For i = 1 To 5
        Set tempTruck = New clsTrucks
        'Random data
        tempTruck.truckID = "Truck" & i
        tempTruck.truckAxleSpacings = 13.5 + i
        tempTruck.truckNumberOfAxles = 20.5 + i

        'tempTruck.truckID is the collection key
        TruckCollection.Add tempTruck, tempTruck.truckID
    Next i

    'retrieve 5 trucks
    For i = 1 To 5
        'retrieve by collection index
        Debug.Print TruckCollection(i).truckAxleSpacings
        'retrieve by key
        Debug.Print TruckCollection("Truck" & i).truckAxleSpacings

    Next i

End Sub

There are several ways of doing this so it really depends on how you intend to use the data as to whether an a class/collection is the best setup or arrays/dictionaries etc.

The method for converting a string to a long is Long.parseLong. Modifying your example:

String s = "1333073704000";
long l = Long.parseLong(s);
// Now l = 1333073704000

This is working in my project. I think, This will be helpful for you.

If Date is in past then invert will 1.
If Date is in future then invert will 0.

$defaultDate = date('Y-m-d');   
$datetime1   = new DateTime('2013-03-10');  
$datetime2   = new DateTime($defaultDate);  
$interval    = $datetime1->diff($datetime2);  
$days        = $interval->format('%a');
$invert      = $interval->invert;

Just write this your work get done

sudo rm /etc/nginx/sites-enabled/default

sudo service nginx restart

systemctl status nginx

Happy Learning

Just use simple properties.

var tomorrow = currentDateTime.Date + 1;  
var eventsCustom = eventCustomRepository.FindAllEventsCustomByUniqueStudentReference(userDevice.UniqueStudentReference)
                            .Where(x =>  x.DateTimeStart >= currentDateTime.Date 
                                   and x.DateTimeStart < tomorrow);

If future dates are not possible in your app, then >= x.DateTimeStart >= currentDateTime.Date is sufficient.

if you have more complex date comparisons, then check Canonical functions and if you have EF6+ DB functions

More Generally - For people searching for issues Supported Linq methods in EF can explain similar issues with linq statements that work on Memory base Lists but not in EF.

Since .NET 4.5 the Validators use data-attributes and bounded Javascript to do the validation work, so .NET expects you to add a script reference for jQuery.

There are two possible ways to solve the error:

Disable UnobtrusiveValidationMode:

Add this to web.config:

<configuration>
    <appSettings>
        <add key="ValidationSettings:UnobtrusiveValidationMode" value="None" />
    </appSettings>
</configuration>

It will work as it worked in previous .NET versions and will just add the necessary Javascript to your page to make the validators work, instead of looking for the code in your jQuery file. This is the common solution actually.

Another solution is to register the script:

In Global.asax Application_Start add mapping to your jQuery file path:

void Application_Start(object sender, EventArgs e) 
{
    // Code that runs on application startup
    ScriptManager.ScriptResourceMapping.AddDefinition("jquery", 
    new ScriptResourceDefinition
    {
        Path = "~/scripts/jquery-1.7.2.min.js",
        DebugPath = "~/scripts/jquery-1.7.2.js",
        CdnPath = "http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.4.1.min.js",
        CdnDebugPath = "http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.4.1.js"
    });
}

Some details from MSDN:

ValidationSettings:UnobtrusiveValidationMode Specifies how ASP.NET globally enables the built-in validator controls to use unobtrusive JavaScript for client-side validation logic.

If this key value is set to "None" [default], the ASP.NET application will use the pre-4.5 behavior (JavaScript inline in the pages) for client-side validation logic.

If this key value is set to "WebForms", ASP.NET uses HTML5 data-attributes and late bound JavaScript from an added script reference for client-side validation logic.

Node.js csvtojson module is a comprehensive nodejs csv parser. It can be used as node.js app library / a command line tool / or browser with help of browserify or webpack.

the source code can be found at: https://github.com/Keyang/node-csvtojson

2. Use it in your node.js app:

// require csvtojson
var csv = require("csvtojson");

// Convert a csv file with csvtojson
csv()
  .fromFile(csvFilePath)
  .then(function(jsonArrayObj){ //when parse finished, result will be emitted here.
     console.log(jsonArrayObj); 
   })

// Parse large csv with stream / pipe (low mem consumption)
csv()
  .fromStream(readableStream)
  .subscribe(function(jsonObj){ //single json object will be emitted for each csv line
     // parse each json asynchronousely
     return new Promise(function(resolve,reject){
         asyncStoreToDb(json,function(){resolve()})
     })
  }) 

//Use async / await
const jsonArray=await csv().fromFile(filePath);

Static Object: We can define class members static using static keyword. When we declare a member of a class as static it means no matter how many objects of the class are created, there is only one copy of the static member.

A static member is shared by all objects of the class. All static data is initialized to zero when the first object is created, if no other initialization is present. We can't put it in the class definition but it can be initialized outside the class as done in the following example by redeclaring the static variable, using the scope resolution operator :: to identify which class it belongs to.

Let us try the following example to understand the concept of static data members:

#include <iostream>

using namespace std;

class Box
{
   public:
      static int objectCount;
      // Constructor definition
      Box(double l=2.0, double b=2.0, double h=2.0)
      {
         cout <<"Constructor called." << endl;
         length = l;
         breadth = b;
         height = h;
         // Increase every time object is created
         objectCount++;
      }
      double Volume()
      {
         return length * breadth * height;
      }
   private:
      double length;     // Length of a box
      double breadth;    // Breadth of a box
      double height;     // Height of a box
};

// Initialize static member of class Box
int Box::objectCount = 0;

int main(void)
{
   Box Box1(3.3, 1.2, 1.5);    // Declare box1
   Box Box2(8.5, 6.0, 2.0);    // Declare box2

   // Print total number of objects.
   cout << "Total objects: " << Box::objectCount << endl;

   return 0;
}

When the above code is compiled and executed, it produces the following result:

Constructor called.
Constructor called.
Total objects: 2

Static Function Members: By declaring a function member as static, you make it independent of any particular object of the class. A static member function can be called even if no objects of the class exist and the static functions are accessed using only the class name and the scope resolution operator ::.

A static member function can only access static data member, other static member functions and any other functions from outside the class.

Static member functions have a class scope and they do not have access to the this pointer of the class. You could use a static member function to determine whether some objects of the class have been created or not.

Let us try the following example to understand the concept of static function members:

#include <iostream>

using namespace std;

class Box
{
   public:
      static int objectCount;
      // Constructor definition
      Box(double l=2.0, double b=2.0, double h=2.0)
      {
         cout <<"Constructor called." << endl;
         length = l;
         breadth = b;
         height = h;
         // Increase every time object is created
         objectCount++;
      }
      double Volume()
      {
         return length * breadth * height;
      }
      static int getCount()
      {
         return objectCount;
      }
   private:
      double length;     // Length of a box
      double breadth;    // Breadth of a box
      double height;     // Height of a box
};

// Initialize static member of class Box
int Box::objectCount = 0;

int main(void)
{

   // Print total number of objects before creating object.
   cout << "Inital Stage Count: " << Box::getCount() << endl;

   Box Box1(3.3, 1.2, 1.5);    // Declare box1
   Box Box2(8.5, 6.0, 2.0);    // Declare box2

   // Print total number of objects after creating object.
   cout << "Final Stage Count: " << Box::getCount() << endl;

   return 0;
}

When the above code is compiled and executed, it produces the following result:

Inital Stage Count: 0
Constructor called.
Constructor called.
Final Stage Count: 2

You are trying to run Java code with Python. In Python/Selenium, the org.openqa.selenium.interactions.Actions are reflected in ActionChains class:

from selenium.webdriver.common.action_chains import ActionChains

element = driver.find_element_by_id("my-id")

actions = ActionChains(driver)
actions.move_to_element(element).perform()

Or, you can also "scroll into view" via scrollIntoView():

driver.execute_script("arguments[0].scrollIntoView();", element)

If you are interested in the differences:

• scrollIntoView vs moveToElement

Iterate through it and count the elements which aren't null:

int counter = 0;
for (int i = 0; i < theArray.length; i ++)
    if (theArray[i] != null)
        counter ++;

This can be neatened up by using for:each loops and suchlike, but this is the jist.

Either that, or keep a counter and whenever you add an element, increment it.

Spring Boot 2.2.2 / Gradle:

Gradle (build.gradle):

implementation("com.fasterxml.jackson.datatype:jackson-datatype-jsr310")

Entity (User.class):

LocalDate dateOfBirth;

Code:

ObjectMapper mapper = new ObjectMapper();
mapper.registerModule(new JavaTimeModule());
User user = mapper.readValue(json, User.class);

This will do it recursively for you:

find /path/to/base/dir/* -type d -ctime +10 -exec rm -rf {} \;

Explanation:

• find: the unix command for finding files / directories / links etc.
• /path/to/base/dir: the directory to start your search in.
• -type d: only find directories
• -ctime +10: only consider the ones with modification time older than 10 days
• -exec ... \;: for each such result found, do the following command in ...
• rm -rf {}: recursively force remove the directory; the {} part is where the find result gets substituted into from the previous part.

Alternatively, use:

find /path/to/base/dir/* -type d -ctime +10 | xargs rm -rf

Which is a bit more efficient, because it amounts to:

rm -rf dir1 dir2 dir3 ...

as opposed to:

rm -rf dir1; rm -rf dir2; rm -rf dir3; ...

as in the -exec method.

With modern versions of find, you can replace the ; with + and it will do the equivalent of the xargs call for you, passing as many files as will fit on each exec system call:

find . -type d -ctime +10 -exec rm -rf {} +

    pgrep -f process_name > any_file_name
    sed -i 's/^/kill /' any_file_name
    chmod 777 any_file_name
    ./any_file_name

for example 'pgrep -f firefox' will grep the PID of running 'firefox' and will save this PID to a file called 'any_file_name'. 'sed' command will add the 'kill' in the beginning of the PID number in 'any_file_name' file. Third line will make 'any_file_name' file executable. Now forth line will kill the PID available in the file 'any_file_name'. Writing the above four lines in a file and executing that file can do the control-C. Working absolutely fine for me.

I needed to switch between two images. With conditional switching between them there was 5sec delay with no image displayed.

I'm using approach from downvoted amos answer. Posting as new answer because it's hard to put code into comment with proper formatting.

Render function:

<View style={styles.logoWrapper}>
  <Image
    style={[styles.logo, loading ? styles.hidden : {}]}
    source={require('./logo.png')} />
  <Image
    style={[styles.logo, loading ? {} : styles.hidden]}
    source={require('./logo_spin.gif')} />
</View>

Styles:

var styles = StyleSheet.create({
  logo: {
    width: 200,
    height: 200,
  },
  hidden: {
    width: 0,
    height: 0,

});

Can you use default android Crop functionality?

Here is my code

private void performCrop(Uri picUri) {
    try {
        Intent cropIntent = new Intent("com.android.camera.action.CROP");
        // indicate image type and Uri
        cropIntent.setDataAndType(picUri, "image/*");
        // set crop properties here
        cropIntent.putExtra("crop", true);
        // indicate aspect of desired crop
        cropIntent.putExtra("aspectX", 1);
        cropIntent.putExtra("aspectY", 1);
        // indicate output X and Y
        cropIntent.putExtra("outputX", 128);
        cropIntent.putExtra("outputY", 128);
        // retrieve data on return
        cropIntent.putExtra("return-data", true);
        // start the activity - we handle returning in onActivityResult
        startActivityForResult(cropIntent, PIC_CROP);
    }
    // respond to users whose devices do not support the crop action
    catch (ActivityNotFoundException anfe) {
        // display an error message
        String errorMessage = "Whoops - your device doesn't support the crop action!";
        Toast toast = Toast.makeText(this, errorMessage, Toast.LENGTH_SHORT);
        toast.show();
    }
}

declare:

final int PIC_CROP = 1;

at top.

In onActivity result method, writ following code:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if (requestCode == PIC_CROP) {
        if (data != null) {
            // get the returned data
            Bundle extras = data.getExtras();
            // get the cropped bitmap
            Bitmap selectedBitmap = extras.getParcelable("data");

            imgView.setImageBitmap(selectedBitmap);
        }
    }
}

It is pretty easy for me to implement and also shows darken areas.

There's a property in CSS called box-sizing. It determines the total width of an element on your page. The default value is content-box, which doesn't include the padding, margin, or border of the element.

Hence, if you set a div to have width: 500px and 20px padding all around, it will take up 540px on your website (500 + 20 + 20).

This is what is causing your problem. Bootstrap calculates set widths for things just like the above example, and these things don't have borders. Since Bootstrap fits together like a puzzle, adding a border to one of the sides would yield a total width of 501px (continuing the above example) and break your layout.

The easiest way to fix this is to adjust your box-sizing. The value you would use is box-sizing: border-box. This includes the padding and border in your box elements. You can read more about box-sizing here.

A problem with this solution is that it only works on IE8+. Consequently, if you need deeper IE support you'll need to override the Bootstrap widths to account for your border.

To give an example of how to calculate a new width, begin by checking the width that Bootstrap sets on your element. Let's say it's a span6 and has a width of 320px (this is purely hypothetical, the actual width of your span6 will depend on your specific configuration of Bootstrap). If you wanted to add a single border on the right hand side with a 20px padding over there, you'd write this CSS in your stylesheet

.span6 {
  padding-right: 20px;
  border-right: 1px solid #ddd;
  width: 299px;
 }

where the new width is calculated by:

old width - padding - border

It's just a variable name, and it's conventional in python to use _ for throwaway variables. It just indicates that the loop variable isn't actually used.

Universal and fast method (without Math.Pow() / multiplication) for System.Decimal:

decimal Truncate(decimal d, byte decimals)
{
    decimal r = Math.Round(d, decimals);

    if (d > 0 && r > d)
    {
        return r - new decimal(1, 0, 0, false, decimals);
    }
    else if (d < 0 && r < d)
    {
        return r + new decimal(1, 0, 0, false, decimals);
    }

    return r;
}

The answer here worked better for me as it isolates the search on the hashtag, not just returning results that contain the search string. In the answer above you would still need to parse the JSON response to see if the entities.hashtags array is not empty.

theme root directory path code

 <?php $root_path = get_home_path(); ?> 
print "Path: ".$root_path;

Return "Path: /var/www/htdocs/" or "Path: /var/www/htdocs/wordpress/" if it is subfolder

Theme Root Path

 $theme_root = get_theme_root();
 echo $theme_root

Results:- /home/user/public_html/wp-content/themes

<?php
function writeUTF8File($filename,$content) { 
        $f=fopen($filename,"w"); 
        # Now UTF-8 - Add byte order mark 
        fwrite($f, pack("CCC",0xef,0xbb,0xbf)); 
        fwrite($f,$content); 
        fclose($f); 
} 
?>

First thing you need to do here is correct the hibernate dialect version like @JavaLearner has explained. Then you have make sure that all the versions of hibernate dependencies you are using are upto date. Typically you would need: database driver like mysql-connector-java, hibernate dependency: hibernate-core and hibernate entity manager: hibernate-entitymanager. Lastly don't forget to check that the database tables you are using are not the reserved words like order, group, limit, etc. It might save you a lot of headache.

If you're in a client-side web environment, the new auth2 javascript API contains a much-needed getBasicProfile() function, which returns the user's name, email, and image URL.

It is not faster. There is one difference when you can initialize a constant variable depending on some expression:

const int x = (a<b) ? b : a;

You can't do the same with if-else.

var objToJson = { };
objToJson.response = response;
response.write(JSON.stringify(objToJson));

If you alert(JSON.stringify(objToJson)) you will get {"response":"value"}

I added the following code in proguard file.

-keep public class * extends android.app.Activity_x000D_
-keep public class * extends android.app.Application

and it worked in my case.

sudo arduino is the only way I get the Arduino IDE working (serial port and upload) on ubuntu 12.04 (64) Indeed the serial port to use is /dev/ttyACM0 in my case too. The other two (ttyS4 and ttyS0) gave an error when trying to upload to Uno. Have fun

>>> int('101111',2)
47

Convert Decimal to binary

>>> bin(47)
'0b101111'

Place a 0 as the second parameter python assumes it as decimal.

>>> int('101111',0)
101111

CURL is the simplest way to go. Here is a simple call

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "THE URL TO THE SERVICE");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, POST DATA);
$result = curl_exec($ch);


print_r($result);
curl_close($ch);

If this server is visible to the outside world, It's worth checking if it's having lots of requests to connect from the outside world (i.e. people trying to break into it)

JSONArray jsonArray = new JSONArray();

for (loop) {
    JSONObject jsonObj= new JSONObject();
    jsonObj.put("srcOfPhoto", srcOfPhoto);
    jsonObj.put("username", "name"+count);
    jsonObj.put("userid", "userid"+count);

    jsonArray.put(jsonObj.valueToString());
}

JSONObject parameters = new JSONObject();

parameters.put("action", "remove");

parameters.put("datatable", jsonArray );

parameters.put(Constant.MSG_TYPE , Constant.SUCCESS);

Why were you using an Hashmap if what you wanted was to put it into a JSONObject?

EDIT: As per http://www.json.org/javadoc/org/json/JSONArray.html

EDIT2: On the JSONObject method used, I'm following the code available at: https://github.com/stleary/JSON-java/blob/master/JSONObject.java#L2327 , that method is not deprecated.

We're storing a string representation of the JSONObject, not the JSONObject itself

In Bootstrap 4.3, col-xs-{value} is replaced by col-{value}

There is no change in sm, md, lg, xl remains the same.

.col-{value}
.col-sm-{value}
.col-md-{value}
.col-lg-{value}
.col-xl-{value}

You are using " instead of ' It is mixing up php syntax with javascript. PHP is going to print javascript with echo function, but it is taking the js codes as wrong php syntax. so try this,

<html>

echo "<script type='text/javascript'>";
echo "document.write('Hello World!')";
echo "</script>";

?>

There are many possibilities. Simplest way is to just use pgAdmin and get this from SQL window. However if you want to get this programmatically then examinate pg_proc and pg_trigger system catalogs or routines and triggers views from information schema (that's SQL standard way, but it might not cover all features especially PostgreSQL-specific). For example:

SELECT
    routine_definition 
FROM
    information_schema.routines 
WHERE
    specific_schema LIKE 'public'
    AND routine_name LIKE 'functionName';

Check Java versions That was a problem for me. IDE (Intellij in my case) could launch without the problem, but when I tried to run war inside tomcat docker image app didn't work. The reason was docker image had a different (lower) version compare to the development environment. There were no errors messages indicating any of this.

You can combine it with selected and hidden

<select class="dropdown" style="width: 150px; height: 26px">
        <option selected hidden>What is your name?</option>
        <option value="michel">Michel</option>
        <option value="thiago">Thiago</option>
        <option value="Jonson">Jonson</option>
</select>

Your dropdown title will be selected and cannot chose by the user.

While the answers that you can't parse HTML with regexes are correct, they don't apply here. The OP just wants to parse one HTML tag with regexes, and that is something that can be done with a regular expression.

The suggested regex is wrong, though:

<([a-z]+) *[^/]*?>

If you add something to the regex, by backtracking it can be forced to match silly things like <a >>, [^/] is too permissive. Also note that <space>*[^/]* is redundant, because the [^/]* can also match spaces.

My suggestion would be

<([a-z]+)[^>]*(?<!/)>

Where (?<! ... ) is (in Perl regexes) the negative look-behind. It reads "a <, then a word, then anything that's not a >, the last of which may not be a /, followed by >".

Note that this allows things like <a/ > (just like the original regex), so if you want something more restrictive, you need to build a regex to match attribute pairs separated by spaces.

I might be misunderstanding your question, so apologies if I am.

If you're looking for the words "Quid", "Application Number", etc. to be bold, just wrap them in <strong> tags:

<strong>Quid</strong>: ...

Hope that helps!

In Android Studio 4.0 you need only these few steps:

• in File Manager copy the project directory and rename the new one
• enter in it and change applicationId inside app/build.gradle
• open the existing new project in Android Studio
• open one class file and highlight the package name part to change (e.g. from com.domain.appname to com.domain.newappname highlight appname)
• right click on it -> "refactor" -> "rename"
• choose "rename package"
• in the dialog choose "Scope: all places" and click "preview" or "refactor"

The best way to Install new themes in any Eclipse platform is to use the Eclipse Marketplace.

1.Go to Help > Eclipse Marketplace

2.Search for "Color Themes"

3.Install and Restart

4.Go to Window > Preferences > General > Appearance > Color Themes

5.Select anyone and Apply. Restart.

For this particular question, the standard suggestion of java.text.SimpleDateFormat works, but has the unfortunate side effect that SimpleDateFormat is not thread-safe and can be the source of particularly nasty problems since it'll corrupt your output in multi-threaded scenarios, and you won't get any exceptions!

I would strongly recommend looking at Joda for anything like this. Why ? It's a much richer and more intuitive time/date library for Java than the current library (and the basis of the up-and-coming new standard Java date/time library, so you'll be learning a soon-to-be-standard API).

They seem to continuously change stuff in Chrome, but here's what works right now :-)

• First you must click on the red record button or you'll get nothing.

• I never noticed the WS before but it filters out the web socket connections.

• Select it and then you can see the Frames (now called Messages) which will show you error messages etc.

A Swift Approach

This answer builds on the answers above and provides implementation for dealing with the problem of the gradient not being properly applied during rotation. It satisfies this problem by changing the gradient layer to a square so that rotation in all directions results in a correct gradient. The function signature includes a Swift variadic argument that allows one to pass in as many CGColorRef's (CGColor) as needed (see sample usage). Also provided is an example as a Swift extension so that one can apply a gradient to any UIView.

   func configureGradientBackground(colors:CGColorRef...){

        let gradient: CAGradientLayer = CAGradientLayer()
        let maxWidth = max(self.view.bounds.size.height,self.view.bounds.size.width)
        let squareFrame = CGRect(origin: self.view.bounds.origin, size: CGSizeMake(maxWidth, maxWidth))
        gradient.frame = squareFrame

        gradient.colors = colors
        view.layer.insertSublayer(gradient, atIndex: 0)
    }

To use:

in viewDidLoad...

  override func viewDidLoad() {
        super.viewDidLoad()
        configureGradientBackground(UIColor.redColor().CGColor, UIColor.whiteColor().CGColor)
  }

Extension implementation

extension CALayer {


    func configureGradientBackground(colors:CGColorRef...){

        let gradient = CAGradientLayer()

        let maxWidth = max(self.bounds.size.height,self.bounds.size.width)
        let squareFrame = CGRect(origin: self.bounds.origin, size: CGSizeMake(maxWidth, maxWidth))
        gradient.frame = squareFrame

        gradient.colors = colors

        self.insertSublayer(gradient, atIndex: 0)
    }

}

Extension use-case example:

 override func viewDidLoad() {
        super.viewDidLoad()

        self.view.layer.configureGradientBackground(UIColor.purpleColor().CGColor, UIColor.blueColor().CGColor, UIColor.whiteColor().CGColor)
 }

Which means the gradient background can now be applied to any UIControl since all controls are UIViews (or a subclass) and all UIViews have CALayers.

Swift 4

Extension implementation

extension CALayer {
    public func configureGradientBackground(_ colors:CGColor...){

        let gradient = CAGradientLayer()

        let maxWidth = max(self.bounds.size.height,self.bounds.size.width)
        let squareFrame = CGRect(origin: self.bounds.origin, size: CGSize(width: maxWidth, height: maxWidth))
        gradient.frame = squareFrame

        gradient.colors = colors

        self.insertSublayer(gradient, at: 0)
    }    
}

Extension use-case example:

override func viewDidLoad() {
    super.viewDidLoad()

    self.view.layer.configureGradientBackground(UIColor.purple.cgColor, UIColor.blue.cgColor, UIColor.white.cgColor)
}

Docotic.Pdf library may be used to accomplish the task.

Here is sample code:

PdfDocument document = new PdfDocument();
document.Open("file.pdf");
int pageCount = document.PageCount;

The library will parse as little as possible so performance should be ok.

The Chapter object should have reference to the book it came from so I would suggest something like chapter.getBook().getTitle();

Your database table structure should have a books table and a chapters table with columns like:

books

• id
• book specific info
• etc

chapters

• id
• book_id
• chapter specific info
• etc

Then to reduce the number of queries use a join table in your search query.

About this, java declares that on Windows 10, Edge browser does not support plugins, so it will NOT run java. (see https://www.java.com/it/download/win10.jsp --> only visible with edge in win10) It also reports a notice: java is not officially supported yet in Windows 10. (see https://www.java.com/it/download/faq/win10_faq.xml)

Watch out for the trap I got into: When checking if certain value is not present in an array, you shouldn't do:

SELECT value_variable != ANY('{1,2,3}'::int[])

but use

SELECT value_variable != ALL('{1,2,3}'::int[])

instead.

If you're on windows you can bypass the socket issue completely by switching to shared memory debugging.

Use the replace function in js:

var emailAdd = $(this).text().replace(/ /g,'');

That will remove all the spaces

If you want to remove the leading and trailing whitespace only, use the jQuery $.trim method :

var emailAdd = $.trim($(this).text());

I prefer to use two options, white spaces and empty:

test = test.Where(x => !string.IsNullOrEmpty(x)).ToArray();
test = test.Where(x => !string.IsNullOrWhiteSpace(x)).ToArray();

The accepted anwser using cmd.exe and

for /F "tokens=*" %F in (file.txt) do whatever "%F" ...

works only for "normal" files. It fails miserably with huge files.

For big files, you may need to use Powershell and something like this:

[IO.File]::ReadLines("file.txt") | ForEach-Object { whatever "$_" }

or if you have enough memory:

foreach($line in [System.IO.File]::ReadLines("file.txt")) { whatever "$line" } 

This worked for me with a 250 MB file containing over 2 million lines, where the for /F ... command got stuck after a few thousand lines.

For the differences between foreach and ForEach-Object, see Getting to Know ForEach and ForEach-Object.

CARL LANGE also showed how to get hidden, autoplaying audio in html5 on a iOS device. Works for me.

In HTML,

<div id="hideme">
    <audio id="audioTag" controls>
        <source src="/path/to/audio.mp3">
    </audio>
</div>

with JS

<script type="text/javascript">
window.onload = function() {
    var audioEl = document.getElementById("audioTag");
    audioEl.load();
    audioEl.play();
};
</script>

In CSS,

#hideme {display: none;}

Try:

select
     id,
     StartDate,
CASE WHEN StartDate IS NULL
    THEN 'Awaiting'
    ELSE 'Approved' END AS StartDateStatus
FROM myTable

You code would have been doing a When StartDate = NULL, I think.

NULL is never equal to NULL (as NULL is the absence of a value). NULL is also never not equal to NULL. The syntax noted above is ANSI SQL standard and the converse would be StartDate IS NOT NULL.

You can run the following:

SELECT CASE WHEN (NULL = NULL) THEN 1 ELSE 0 END AS EqualityCheck,
CASE WHEN (NULL <> NULL) THEN 1 ELSE 0 END AS InEqualityCheck,
CASE WHEN (NULL IS NULL) THEN 1 ELSE 0 END AS NullComparison

And this returns:

EqualityCheck = 0
InEqualityCheck = 0
NullComparison = 1

For completeness, in SQL Server you can:

SET ANSI_NULLS OFF;

Which would result in your equals comparisons working differently:

SET ANSI_NULLS OFF

SELECT CASE WHEN (NULL = NULL) THEN 1 ELSE 0 END AS EqualityCheck,
CASE WHEN (NULL <> NULL) THEN 1 ELSE 0 END AS InEqualityCheck,
CASE WHEN (NULL IS NULL) THEN 1 ELSE 0 END AS NullComparison

Which returns:

EqualityCheck = 1
InEqualityCheck = 0
NullComparison = 1

But I would highly recommend against doing this. People subsequently maintaining your code might be compelled to hunt you down and hurt you...

Also, it will no longer work in upcoming versions of SQL server:

https://msdn.microsoft.com/en-GB/library/ms188048.aspx

You can also use the Pivot Keyword if you are using SQL 2005 or above

more info and from Technet

    FOR Position

SilverSkin and Anders are both correct. You can use parentheses to execute multiple commands. However, you have to make sure that the commands themselves (and their parameters) do not contain parentheses. cmd greedily searches for the first closing parenthesis, instead of handling nested sets of parentheses gracefully. This may cause the rest of the command line to fail to parse, or it may cause some of the parentheses to get passed to the commands (e.g. DEL myfile.txt)).

A workaround for this is to split the body of the loop into a separate function. Note that you probably need to jump around the function body to avoid "falling through" into it.

FOR /r %%X IN (*.txt) DO CALL :loopbody %%X
REM Don't "fall through" to :loopbody.
GOTO :EOF

:loopbody
ECHO %1
DEL %1
GOTO :EOF

I'm a total novice but surely this is cleaner and more controlled

def main():

Edit

The point being that the program ends smoothly and peacefully, rather than "I'VE STOPPED !!!!"

Try this out:

<script type="text/javascript">
    function test
    {
        alert("hello world");  //write your logic here like ajax
    }
</script>

<form action="javascript:test();" >

    lastName : <input type="text" name="lastName" id="lastName" required/><br/>
    email : <input type="email" name="email" id="email"/><br/>
    <input type="submit" value="Get It!" name="submit" id="submit"/>
</form>

PHP way of getting text from span tag:

$spanText = $this->webDriver->findElement(WebDriverBy::xpath("//*[@id='specInformation']/tbody/tr[2]/td[1]/span[1]"))->getText();

In case you're using Gradle Kotlin syntax, you also can do:

tasks.taskName {
    environment(mapOf("A" to 1, "B" to "C"))
}

So for test task this would be:

tasks.test {
    environment(mapOf("SOME_TEST_VAR" to "aaa"))
}

There's a handy function, oidvectortypes, that makes this a lot easier.

SELECT format('%I.%I(%s)', ns.nspname, p.proname, oidvectortypes(p.proargtypes)) 
FROM pg_proc p INNER JOIN pg_namespace ns ON (p.pronamespace = ns.oid)
WHERE ns.nspname = 'my_namespace';

Credit to Leo Hsu and Regina Obe at Postgres Online for pointing out oidvectortypes. I wrote similar functions before, but used complex nested expressions that this function gets rid of the need for.

See related answer.

(edit in 2016)

Summarizing typical report options:

-- Compact:
SELECT format('%I.%I(%s)', ns.nspname, p.proname, oidvectortypes(p.proargtypes))

-- With result data type: 
SELECT format(
       '%I.%I(%s)=%s', 
       ns.nspname, p.proname, oidvectortypes(p.proargtypes),
       pg_get_function_result(p.oid)
)

-- With complete argument description: 
SELECT format('%I.%I(%s)', ns.nspname, p.proname, pg_get_function_arguments(p.oid))

-- ... and mixing it.

-- All with the same FROM clause:
FROM pg_proc p INNER JOIN pg_namespace ns ON (p.pronamespace = ns.oid)
WHERE ns.nspname = 'my_namespace';

NOTICE: use p.proname||'_'||p.oid AS specific_name to obtain unique names, or to JOIN with information_schema tables — see routines and parameters at @RuddZwolinski's answer.

The function's OID (see pg_catalog.pg_proc) and the function's specific_name (see information_schema.routines) are the main reference options to functions. Below, some useful functions in reporting and other contexts.

The most succinct explanation I found was in the AirBNB style guide:

• Primitives: When you access a primitive type you work directly on its value

  • string
  • number
  • boolean
  • null
  • undefined

E.g.:

var foo = 1,
    bar = foo;

bar = 9;

console.log(foo, bar); // => 1, 9

• Complex: When you access a complex type you work on a reference to its value

  • object
  • array
  • function

E.g.:

var foo = [1, 2],
    bar = foo;

bar[0] = 9;

console.log(foo[0], bar[0]); // => 9, 9

I.e. effectively primitive types are passed by value, and complex types are passed by reference.

I learned today that there is a limit you want to use for the fill-mode. This is from an Apple dev. Rumor is * around * six, but not certain. Alternatively, you can set the initial state of your class to how you want the animation to end, then * initialize * it at from / 0% .

Yes, There are other shortcuts that you can use which are given below. In your command, ~d0 would mean the drive letter of the 0th argument.

~ expands the given variable
d gets the drive letter only
0 is the argument you are referencing

As the 0th argument is the script path, it gets the drive letter of the path for you. You can use the following shortcuts too.

%~1         - expands %1 removing any surrounding quotes (")
%~f1        - expands %1 to a fully qualified path name
%~d1        - expands %1 to a drive letter only
%~p1        - expands %1 to a path only
%~n1        - expands %1 to a file name only
%~x1        - expands %1 to a file extension only
%~s1        - expanded path contains short names only
%~a1        - expands %1 to file attributes
%~t1        - expands %1 to date/time of file
%~z1        - expands %1 to size of file
%~$PATH:1   - searches the directories listed in the PATH
               environment variable and expands %1 to the fully
               qualified name of the first one found.  If the
               environment variable name is not defined or the
               file is not found by the search, then this
               modifier expands to the empty string    

%~dp1       - expands %1 to a drive letter and path only
%~nx1       - expands %1 to a file name and extension only
%~dp$PATH:1 - searches the directories listed in the PATH
               environment variable for %1 and expands to the
               drive letter and path of the first one found.
%~ftza1     - expands %1 to a DIR like output line

This can be also found directly in command prompt when you run CALL /? or FOR /?

textField_in = new JTextField();
textField_in.addKeyListener(new KeyAdapter() {

    @Override

        System.out.println(arg0.getExtendedKeyCode());
        if (arg0.getKeyCode()==10) {
            String name = textField_in.getText();
            textField_out.setText(name);
        }

    }

});
textField_in.setBounds(173, 40, 86, 20);

textField_in.setColumns(10);

The documentation is here: http://docs.jquery.com/Ajax/jQuery.ajax

But, to summarize, the ajax call takes a bunch of options. the ones you are looking for are error and success.

You would call it like this:

$.ajax({
  url: 'mypage.html',
  success: function(){
    alert('success');

  error: function(){
    alert('failure');

});

I have shown the success and error function taking no arguments, but they can receive arguments.

The error function can take three arguments: XMLHttpRequest, textStatus, and errorThrown.

The success function can take two arguments: data and textStatus. The page you requested will be in the data argument.

I found this today, it is from 2003. It finds a process by name, you don't even need the pid.

PHP also has money_format().

Here's an example:

echo money_format('$%i', 3.4); // echos '$3.40'

This function actually has tons of options, go to the documentation I linked to to see them.

Note: money_format is undefined in Windows.

UPDATE: Via the PHP manual: https://www.php.net/manual/en/function.money-format.php

WARNING: This function [money_format] has been DEPRECATED as of PHP 7.4.0. Relying on this function is highly discouraged.

Instead, look into NumberFormatter::formatCurrency.

    $number = "123.45";
    $formatter = new NumberFormatter('en_US', NumberFormatter::CURRENCY);
    return $formatter->formatCurrency($number, 'USD');

You can set the type of error reporting you need in php.ini or by using the error_reporting() function on top of your script.

This answer from here helped me:

You should take a look at the build path of your project to check whether the referenced libraries are still there. So right-click on your project, then "Properties -> Java Build Path -> Libraries" and check whether you still have the spring library JARs in the place that is mentioned there. If not, just re-add them to your classpath within this dialog.

http://forum.spring.io/forum/spring-projects/springsource-tool-suite/98653-springframework-cannot-be-resolved-error

What I can think of is to stretch either width or height and let it resize in ratio-aspect. There will be some white space on the sides. Something like how a Wide screen displays a resolution of 1024x768.

If you want to have the ListView in an AppCompatActivity instead of ListActivity, you can do the following (Modifying @Shardul's answer):

public class ListViewDemoActivity extends AppCompatActivity {
    //LIST OF ARRAY STRINGS WHICH WILL SERVE AS LIST ITEMS
    ArrayList<String> listItems=new ArrayList<String>();

    //DEFINING A STRING ADAPTER WHICH WILL HANDLE THE DATA OF THE LISTVIEW
    ArrayAdapter<String> adapter;

    //RECORDING HOW MANY TIMES THE BUTTON HAS BEEN CLICKED
    int clickCounter=0;
    private ListView mListView;

    @Override
    public void onCreate(Bundle icicle) {
        super.onCreate(icicle);
        setContentView(R.layout.activity_list_view_demo);

        if (mListView == null) {
            mListView = (ListView) findViewById(R.id.listDemo);
        }

        adapter=new ArrayAdapter<String>(this,
                android.R.layout.simple_list_item_1,
                listItems);
        setListAdapter(adapter);
    }

    //METHOD WHICH WILL HANDLE DYNAMIC INSERTION
    public void addItems(View v) {
        listItems.add("Clicked : "+clickCounter++);
        adapter.notifyDataSetChanged();
    }

    protected ListView getListView() {
        if (mListView == null) {
            mListView = (ListView) findViewById(R.id.listDemo);
        }
        return mListView;
    }

    protected void setListAdapter(ListAdapter adapter) {
        getListView().setAdapter(adapter);
    }

    protected ListAdapter getListAdapter() {
        ListAdapter adapter = getListView().getAdapter();
        if (adapter instanceof HeaderViewListAdapter) {
            return ((HeaderViewListAdapter)adapter).getWrappedAdapter();
        } else {
            return adapter;
        }
    }
}

And in you layout instead of using android:id="@android:id/list" you can use android:id="@+id/listDemo"

So now you can have a ListView inside a normal AppCompatActivity.

Use <a> with href instead of a <button> solves my problem.

<ion-nav-buttons side="secondary">
  <a class="button icon-right ion-plus-round" href="#/app/gosomewhere"></a>
</ion-nav-buttons>

If, by some crazy coincidence, you want to convert a string of characters to an integer, you can do that too!

char *num = "1024";
int val = atoi(num); // atoi = ASCII TO Int

val is now 1024. Apparently atoi() is fine, and what I said about it earlier only applies to me (on OS X (maybe (insert Lisp joke here))). I have heard it is a macro that maps roughly to the next example, which uses strtol(), a more general-purpose function, to do the conversion instead:

char *num = "1024";
int val = (int)strtol(num, (char **)NULL, 10); // strtol = STRing TO Long

strtol() works like this:

long strtol(const char *str, char **endptr, int base);

It converts *str to a long, treating it as if it were a base base number. If **endptr isn't null, it holds the first non-digit character strtol() found (but who cares about that).

I think the best and simplest solution is (KISS):

double i = 348842;
double i2 = i/60000;
float k = (float) Math.round(i2 * 100) / 100;

The problem is with your line

x=np.array ([x0*n])

Here you define x as a single-item array of -200.0. You could do this:

x=np.array ([x0,]*n)

or this:

x=np.zeros((n,)) + x0

Note: your imports are quite confused. You import numpy modules three times in the header, and then later import pylab (that already contains all numpy modules). If you want to go easy, with one single

from pylab import *

line in the top you could use all the modules you need.

Try the following:

    NSString *birthday = @"06/15/1977";
    NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
    [formatter setDateFormat:@"MM/dd/yyyy"];
    NSDate *date = [formatter dateFromString:birthday];
    if(date!=nil) {
        NSInteger age = [date timeIntervalSinceNow]/31556926;
        NSDateComponents *components = [[NSCalendar currentCalendar] components:NSCalendarUnitDay | NSCalendarUnitMonth | NSCalendarUnitYear fromDate:date];
        NSInteger day = [components day];
        NSInteger month = [components month];
        NSInteger year = [components year];

        NSLog(@"Day:%d Month:%d Year:%d Age:%d",day,month,year,age);
    }
    [formatter release];

Map<Integer, Point2D> hm = new HashMap<Integer, Point2D>();

No. Any valid string is a valid key. It can even have " as long as you escape it:

{"The \"meaning\" of life":42}

There is perhaps a chance you'll encounter difficulties loading such values into some languages, which try to associate keys with object field names. I don't know of any such cases, however.

The solution from Edward worked for me.

If you want the whole tablix on one sheet with a constant name, specify the PageName in the tablix's Properties. If you set the PageName in the tablix's Properties, you can not use data from the tablix's dataset in your expression.

If you want rows from the tablix grouped into sheets (or you want one sheet with a name based on the data), specify the PageName in the Group Header.

Short-circuiting behavior in operator and, or:

Let's first define a useful function to determine if something is executed or not. A simple function that accepts an argument, prints a message and returns the input, unchanged.

>>> def fun(i):
...     print "executed"
...     return i
... 

One can observe the Python's short-circuiting behavior of and, or operators in the following example:

>>> fun(1)
executed
1
>>> 1 or fun(1)    # due to short-circuiting  "executed" not printed
1
>>> 1 and fun(1)   # fun(1) called and "executed" printed 
executed
1
>>> 0 and fun(1)   # due to short-circuiting  "executed" not printed 
0

Note: The following values are considered by the interpreter to mean false:

        False    None    0    ""    ()    []     {}

Short-circuiting behavior in function: any(), all():

Python's any() and all() functions also support short-circuiting. As shown in the docs; they evaluate each element of a sequence in-order, until finding a result that allows an early exit in the evaluation. Consider examples below to understand both.

The function any() checks if any element is True. It stops executing as soon as a True is encountered and returns True.

>>> any(fun(i) for i in [1, 2, 3, 4])   # bool(1) = True
executed
True
>>> any(fun(i) for i in [0, 2, 3, 4])   
executed                               # bool(0) = False
executed                               # bool(2) = True
True
>>> any(fun(i) for i in [0, 0, 3, 4])
executed
executed
executed
True

The function all() checks all elements are True and stops executing as soon as a False is encountered:

>>> all(fun(i) for i in [0, 0, 3, 4])
executed
False
>>> all(fun(i) for i in [1, 0, 3, 4])
executed
executed
False

Short-circuiting behavior in Chained Comparison:

Additionally, in Python

Comparisons can be chained arbitrarily; for example, x < y <= z is equivalent to x < y and y <= z, except that y is evaluated only once (but in both cases z is not evaluated at all when x < y is found to be false).

>>> 5 > 6 > fun(3)    # same as:  5 > 6 and 6 > fun(3)
False                 # 5 > 6 is False so fun() not called and "executed" NOT printed
>>> 5 < 6 > fun(3)    # 5 < 6 is True 
executed              # fun(3) called and "executed" printed
True
>>> 4 <= 6 > fun(7)   # 4 <= 6 is True  
executed              # fun(3) called and "executed" printed
False
>>> 5 < fun(6) < 3    # only prints "executed" once
executed
False
>>> 5 < fun(6) and fun(6) < 3 # prints "executed" twice, because the second part executes it again
executed
executed
False

Edit:
One more interesting point to note :- Logical and, or operators in Python returns an operand's value instead of a Boolean (True or False). For example:

Operation x and y gives the result if x is false, then x, else y

^{Unlike in other languages e.g. &&, || operators in C that return either 0 or 1.}

Examples:

>>> 3 and 5    # Second operand evaluated and returned 
5                   
>>> 3  and ()
()
>>> () and 5   # Second operand NOT evaluated as first operand () is  false
()             # so first operand returned 

Similarly or operator return left most value for which bool(value) == True else right most false value (according to short-circuiting behavior), examples:

>>> 2 or 5    # left most operand bool(2) == True
2    
>>> 0 or 5    # bool(0) == False and bool(5) == True
5
>>> 0 or ()
()

So, how is this useful? One example is given in Practical Python By Magnus Lie Hetland:
Let’s say a user is supposed to enter his or her name, but may opt to enter nothing, in which case you want to use the default value '<Unknown>'. You could use an if statement, but you could also state things very succinctly:

In [171]: name = raw_input('Enter Name: ') or '<Unknown>'
Enter Name: 

In [172]: name
Out[172]: '<Unknown>'

In other words, if the return value from raw_input is true (not an empty string), it is assigned to name (nothing changes); otherwise, the default '<Unknown>' is assigned to name.

I also used the base_path() function and it worked for me.

If it matters whether the file you're looking for is a directory and not just a file, you could use File.directory? or Dir.exist?. This will return true only if the file exists and is a directory.

As an aside, a more idiomatic way to write the method would be to take advantage of the fact that Ruby automatically returns the result of the last expression inside the method. Thus, you could write it like this:

def directory_exists?(directory)
  File.directory?(directory)
end

Note that using a method is not necessary in the present case.

If you happen to maintain database systems that are running with DST active, check carefully whether they need to be shut down during the transition in fall. Mandy DBS (or other systems as well) don't like passing the same point in (local) time twice, which is exactly what happens when you turn back the clock in fall. SAP has solved this with a (IMHO really neat) workaround - instead of turning back the clock, they just let the internal clock run at half the usual speed for two hours...

I figured it out. I had an error in my cloud formation template that was creating the EC2 instances. As a result, the EC2 instances that were trying to access the above code deploy buckets, were in different regions (not us-west-2). It seems like the access policies on the buckets (owned by Amazon) only allow access from the region they belong in. When I fixed the error in my template (it was wrong parameter map), the error disappeared

If you want to add AUTO_INCREMENT in an existing table, need to run following SQL command:

 ALTER TABLE users ADD id int NOT NULL AUTO_INCREMENT primary key

So the doctors here that are saying "You say that hurts? Then don't do that!" are probably right. But if you really want to, here's one way of passing arguments to a unittest test:

import sys
import unittest

class MyTest(unittest.TestCase):
    USERNAME = "jemima"
    PASSWORD = "password"

    def test_logins_or_something(self):
        print('username : {}'.format(self.USERNAME))
        print('password : {}'.format(self.PASSWORD))


if __name__ == "__main__":
    if len(sys.argv) > 1:
        MyTest.USERNAME = sys.argv.pop()
        MyTest.PASSWORD = sys.argv.pop()
    unittest.main()

that will let you run with:

python mytests.py ausername apassword

You need the argv.pops so your command line params don't mess with unittest's own...

[update] The other thing you might want to look into is using environment variables:

import os
import unittest

class MyTest(unittest.TestCase):
    USERNAME = "jemima"
    PASSWORD = "password"

    def test_logins_or_something(self):
        print('username : {}'.format(self.USERNAME))
        print('password : {}'.format(self.PASSWORD))


if __name__ == "__main__":
    MyTest.USERNAME = os.environ.get('TEST_USERNAME', MyTest.USERNAME)            
    MyTest.PASSWORD = os.environ.get('TEST_PASSWORD', MyTest.PASSWORD)
    unittest.main()

That will let you run with:

TEST_USERNAME=ausername TEST_PASSWORD=apassword python mytests.py

and it has the advantage that you're not messing with unittest's own argument parsing. downside is it won't work quite like that on Windows...

LIB.EXE is the librarian for VS

Changing the width of the container also fixes it rather than changing the width and height of source file.

.SvgImage img{ width:80%; }

This fixes my issue of re sizing svg . you can give any % based on your requirement.

The error you quote has nothing to do with pg_hba.conf; it's failing to connect, not failing to authorize the connection.

Do what the error message says:

Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections

You haven't shown the command that produces the error. Assuming you're connecting on localhost port 5432 (the defaults for a standard PostgreSQL install), then either:

• PostgreSQL isn't running

• PostgreSQL isn't listening for TCP/IP connections (listen_addresses in postgresql.conf)

• PostgreSQL is only listening on IPv4 (0.0.0.0 or 127.0.0.1) and you're connecting on IPv6 (::1) or vice versa. This seems to be an issue on some older Mac OS X versions that have weird IPv6 socket behaviour, and on some older Windows versions.

• PostgreSQL is listening on a different port to the one you're connecting on

• (unlikely) there's an iptables rule blocking loopback connections

(If you are not connecting on localhost, it may also be a network firewall that's blocking TCP/IP connections, but I'm guessing you're using the defaults since you didn't say).

So ... check those:

• ps -f -u postgres should list postgres processes

• sudo lsof -n -u postgres |grep LISTEN or sudo netstat -ltnp | grep postgres should show the TCP/IP addresses and ports PostgreSQL is listening on

BTW, I think you must be on an old version. On my 9.3 install, the error is rather more detailed:

$ psql -h localhost -p 12345
psql: could not connect to server: Connection refused
        Is the server running on host "localhost" (::1) and accepting
        TCP/IP connections on port 12345?

Excellent solutions Xuan, Theller.

For it to work with python 3 make the following changes

import sys, urllib.request

def reporthook(a, b, c):
    print ("% 3.1f%% of %d bytes\r" % (min(100, float(a * b) / c * 100), c))
    sys.stdout.flush()
for url in sys.argv[1:]:
    i = url.rfind("/")
    file = url[i+1:]
    print (url, "->", file)
    urllib.request.urlretrieve(url, file, reporthook)
print

Also, the URL you enter should be preceded by a "http://", otherwise it returns a unknown url type error.

Do you have the line

apply plugin: 'com.google.gms.google-services' 

line at the bottom of your app's build.gradle file?

I saw some errors when it was on the top and as it's written here, it should be at the bottom.

From all I have read you cannot do exactly what you want without javascript. If you float left before text

<div style="float:left;">widget</div> here is some CONTENT, etc.

Your content wraps as expected. But your widget is in the top left. If you instead put the float after the content

here is some CONTENT, etc. <div style="float:left;">widget</div>

Then your content will wrap the last line to the right of the widget if the last line of content can fit to the right of the widget, otherwise no wrapping is done. To make borders and backgrounds actually include the floated area in the previous example, most people add:

here is some CONTENT, etc. <div style="float:left;">widget</div><div style="clear:both;"></div>

In your question you are using bootstrap which just adds row-fluid::after { content: ""} which resolves the border/background issue.

Moving your content up will give you the one line wrap : http://jsfiddle.net/jJNPY/34/

  <div class="container-fluid">
  <div class="row-fluid">
    <div class="offset1 span8 pull-right">
    ... Widget 1...
    </div>
    .... a lot of content ....
    <div class="span8" style="margin-left: 0;">
    ... Widget 2...
    </div>


  </div>

</div><!--/.fluid-container-->

You might want to replace <br/> and </p> tags with newlines before stripping the HTML to prevent it becoming an illegible mess as Tim suggests.

The only way I can think of removing HTML tags but leaving non-HTML between angle brackets would be check against a list of HTML tags. Something along these lines...

replaceAll("\\<[\s]*tag[^>]*>","")

Then HTML-decode special characters such as &. The result should not be considered to be sanitized.

While it is true that you cannot change the type of the column after the DataTable is filled, you can change it after you call FillSchema, but before you call Fill. For example, say the 3rd column is the one you want to convert from double to Int32, you could use:

adapter.FillSchema(table, SchemaType.Source);
table.Columns[2].DataType = typeof (Int32);
adapter.Fill(table);

DPLYR makes this really easy.

x<-santa%>%
   count(Believe)

If you wanted to count by a group; for instance, how many males v females believe, just add a group_by:

x<-santa%>%
   group_by(Gender)%>%
   count(Believe)

Solution for Swift 4:

yourLabel.layer.borderColor = UIColor.green.cgColor

You can use the get_group method:

In [21]: gb.get_group('foo')
Out[21]: 
     A         B   C
0  foo  1.624345   5
2  foo -0.528172  11
4  foo  0.865408  14

Note: This doesn't require creating an intermediary dictionary / copy of every subdataframe for every group, so will be much more memory-efficient than creating the naive dictionary with dict(iter(gb)). This is because it uses data-structures already available in the groupby object.

You can select different columns using the groupby slicing:

In [22]: gb[["A", "B"]].get_group("foo")
Out[22]:
     A         B
0  foo  1.624345
2  foo -0.528172
4  foo  0.865408

In [23]: gb["C"].get_group("foo")
Out[23]:
0     5
2    11
4    14
Name: C, dtype: int64

Place the body of your loop after the while and before the test. The actual body of the while loop should be a no-op.

while 
    check_if_file_present
    #do other stuff
    (( current_time <= cutoff ))
do
    :
done

Instead of the colon, you can use continue if you find that more readable. You can also insert a command that will only run between iterations (not before first or after last), such as echo "Retrying in five seconds"; sleep 5. Or print delimiters between values:

i=1; while printf '%d' "$((i++))"; (( i <= 4)); do printf ','; done; printf '\n'

I changed the test to use double parentheses since you appear to be comparing integers. Inside double square brackets, comparison operators such as <= are lexical and will give the wrong result when comparing 2 and 10, for example. Those operators don't work inside single square brackets.

Integer object would be best. If you must use primitives you can use a value that does not exist in your use case. Negative height does not exist for people, so

public int getHeight(String name){
    if(map.containsKey(name)){
        return map.get(name);
    }else{
        return -1;
    }
}

• Table variables (DECLARE @t TABLE) are visible only to the connection that creates it, and are deleted when the batch or stored procedure ends.

• Local temporary tables (CREATE TABLE #t) are visible only to the connection that creates it, and are deleted when the connection is closed.

• Global temporary tables (CREATE TABLE ##t) are visible to everyone, and are deleted when all connections that have referenced them have closed.

• Tempdb permanent tables (USE tempdb CREATE TABLE t) are visible to everyone, and are deleted when the server is restarted.

You can see the results in MB format, with the division of 1024 x 1024 which is equal to 1 MB.

int dataSize = 1024 * 1024;

System.out.println("Used Memory   : " + (Runtime.getRuntime().totalMemory() - Runtime.getRuntime().freeMemory())/dataSize + " MB");
System.out.println("Free Memory   : " + Runtime.getRuntime().freeMemory()/dataSize + " MB");
System.out.println("Total Memory  : " + Runtime.getRuntime().totalMemory()/dataSize + " MB");
System.out.println("Max Memory    : " + Runtime.getRuntime().maxMemory()/dataSize + " MB");  

My team moved away from Bower and migrated to npm because:

• Programmatic usage was painful
• Bower's interface kept changing
• Some features, like the url shorthand, are entirely broken
• Using both Bower and npm in the same project is painful
• Keeping bower.json version field in sync with git tags is painful
• Source control != package management
• CommonJS support is not straightforward

For more details, see "Why my team uses npm instead of bower".

You want to ask is "what is the difference between a mutable and a non-mutable array or dictionary." Many times there different terms are used to describe things that you already know about. In this case, you can replace the term "mutable" with "dynamic." So, a mutuable dictionary or array is one that is "dynamic" and can change at runtime, whereas a non-mutable dictionary or array is one that is "static" and defined in your code and does not change at runtime (in other words, you will not be adding, deleting or possibly sorting the elements.)

As to how it is done, you are asking us to repeat the documentation here. All you need to do is to search in sample code and the Xcode documentation to see exactly how it is done. But the mutable thing threw me too when I was first learning, so I'll give you that one!

I'm surprised no one mentioned mapping the file into memory: mmap

With this you can access the file as if it were already loaded into memory and the OS will take care of mapping it in and out as possible. Also, if you do this from 2 independent processes and they map the file "shared", they will share the underlying memory.

Once mapped, it will behave like a bytearray. You can use regular expressions, find or any of the other common methods.

Beware that this approach is a little OS specific. It will not be automatically portable.

I believe that by now the above answers are outdated (or at least unclear) so here's my little go at it. I tried compiling ffmpeg with the option --enable-encoders=libx264 and it will give no error but it won't enable anything (I can't seem to find where I found that suggestion).

Anyways step-by-step, first you must compile libx264 yourself because repository version is outdated:

  wget ftp://ftp.videolan.org/pub/x264/snapshots/last_x264.tar.bz2
  tar --bzip2 -xvf last_x264.tar.bz2
  cd x264-snapshot-XXXXXXXX-XXXX/
  ./configure
  make
  sudo make install

And then get and compile ffmpeg with libx264 enabled. I'm using the latest release which is "Happiness":

wget http://ffmpeg.org/releases/ffmpeg-0.11.2.tar.bz2
tar --bzip2 -xvf ffmpeg-0.11.2.tar.bz2
cd ffmpeg-0.11.2/
./configure --enable-libx264 --enable-gpl
make
sudo install

Now finally you have the libx264 codec to encode, to check it you may run

ffmpeg -codecs | grep h264

and you'll see the options you have were the first D means decoding and the first E means encoding

use ng-bind-html-unsafe

it will apply html with text inside like below:

    <li ng-repeat=" opt in opts" ng-bind-html-unsafe="opt.text" >
        {{ opt.text }}
    </li>

1. Kernel Mode

   In Kernel mode, the executing code has complete and unrestricted access to the underlying hardware. It can execute any CPU instruction and reference any memory address. Kernel mode is generally reserved for the lowest-level, most trusted functions of the operating system. Crashes in kernel mode are catastrophic; they will halt the entire PC.

2. User Mode

   In User mode, the executing code has no ability to directly access hardware or reference memory. Code running in user mode must delegate to system APIs to access hardware or memory. Due to the protection afforded by this sort of isolation, crashes in user mode are always recoverable. Most of the code running on your computer will execute in user mode.
