In terms of how this is implemented, this changes the method - from OrderBy/ThenBy to OrderByDescending/ThenByDescending. However, you can apply the sort separately to the main query...

var qry = from .... // or just dataList.AsEnumerable()/AsQueryable()

if(sortAscending) {
    qry = qry.OrderBy(x=>x.Property);
} else {
    qry = qry.OrderByDescending(x=>x.Property);
}

Any use? You can create the entire "order" dynamically, but it is more involved...

Another trick (mainly appropriate to LINQ-to-Objects) is to use a multiplier, of -1/1. This is only really useful for numeric data, but is a cheeky way of achieving the same outcome.

For setting Top Border and Bottom Border for a UIView in Swift.

let topBorder = UIView(frame: CGRect(x: 0, y: 0, width: 10, height: 1))
topBorder.backgroundColor = UIColor.black
myView.addSubview(topBorder)

let bottomBorder = UIView(frame: CGRect(x: 0, y: myView.frame.size.height - 1, width: 10, height: 1))
bottomBorder.backgroundColor = UIColor.black
myView.addSubview(bottomBorder)

   @Bean
    MultipartConfigElement multipartConfigElement() {
        MultipartConfigFactory factory = new MultipartConfigFactory();
        factory.setMaxFileSize("5120MB");
        factory.setMaxRequestSize("5120MB");
        return factory.createMultipartConfig();
    }

put it in class where you are defining beans

You cannot insert data because you have a quota of 0 on the tablespace. To fix this, run

ALTER USER <user> quota unlimited on <tablespace name>;

or

ALTER USER <user> quota 100M on <tablespace name>;

as a DBA user (depending on how much space you need / want to grant).

Just add a new form and add buttons and a label. Give the value to be shown and the text of the button, etc. in its constructor, and call it from anywhere you want in the project.

In project -> Add Component -> Windows Form and select a form

Add some label and buttons.

Initialize the value in constructor and call it from anywhere.

public class form1:System.Windows.Forms.Form
{
    public form1()
    {
    }

    public form1(string message,string buttonText1,string buttonText2)
    {
       lblMessage.Text = message;
       button1.Text = buttonText1;
       button2.Text = buttonText2;
    }
}

// Write code for button1 and button2 's click event in order to call 
// from any where in your current project.

// Calling

Form1 frm = new Form1("message to show", "buttontext1", "buttontext2");
frm.ShowDialog();

The code you wrote will always return true because state cannot be both 10 and 15 for the statement to be false. if ((state != 10) && (state != 15).... AND is what you need not OR.

Use $.inArray instead. This returns the index of the element in the array.

JSFIDDLE DEMO

var statesArray = [10, 15, 19]; // list out all

var index = $.inArray(state, statesArray);

if(index == -1) {
    console.log("Not there in array");
    return true;

} else {
    console.log("Found it");
    return false;
}

Assuming you must have two tables for the two employee types for some reason, I'll extend on vmarquez's answer:

Schema:

employees_ce (id, name)
employees_sn (id, name)
deductions (id, parentId, parentType, name)

Data in deductions:

deductions table
id      parentId      parentType      name
1       1             ce              gold
2       1             sn              silver
3       2             sn              wood
...

This would allow you to have deductions point to any other table in your schema. This kind of relation isn't supported by database-level constraints, IIRC so you'll have to make sure your App manages the constraint properly (which makes it more cumbersome if you have several different Apps/services hitting the same database).

The like operator takes two strings. These strings have to have compatible collations, which is explained here.

In my opinion, things then get complicated. The following query returns an error saying that the collations are incompatible:

select *
from INFORMATION_SCHEMA.TABLES
where 'abc' COLLATE SQL_Latin1_General_CP1_CI_AS like 'ABC' COLLATE SQL_Latin1_General_CP1_CS_AS

On a random machine here, the default collation is SQL_Latin1_General_CP1_CI_AS. The following query is successful, but returns no rows:

select *
from INFORMATION_SCHEMA.TABLES
where 'abc' like 'ABC' COLLATE SQL_Latin1_General_CP1_CS_AS

The values "abc" and "ABC" do not match in a case-sensitve world.

In other words, there is a difference between having no collation and using the default collation. When one side has no collation, then it is "assigned" an explicit collation from the other side.

(The results are the same when the explicit collation is on the left.)

If you don't know, which collection holds your object

In my case it was really hard to apply TomAnderson's solution, since I didn't know what is the collection, which holds a link to an object, so here's the way to know, which objects holds the link to the deleted one: in the debugger you should enter the lowest execution stack level before the exception is thrown, there should be a variable called entityEntry, so you get a PersistenceContext object from this variable: entityEntry.persistenceContext.

For me persistenceContext was an instance of StatefulPersistenceContext and this implementation has private field parentsByChild, from which you can retrieve information about the collection, which contains the element.

I was using Eclipse debugger, so it was kinda hard to retrieve this private field in a straight way, so I used Detail Formatter (How can I watch private fields of other objects directly in the IDE when debugging?)

After getting this information, TomAnderson's solution can be applied.

Try this:

DataTable dt = (DataTable)Session["dtAllOrders"];
DataTable dtSpecificOrders = dt.Clone();

DataRow[] orderRows = dt.Select("CustomerID = 2");

foreach (DataRow dr in orderRows)
{
    dtSpecificOrders.ImportRow(dr);
}

Works fine for me with this

    Calendar cal = Calendar.getInstance(TimeZone.getTimeZone());
    cal.set(Calendar.MONTH, month-1);  
    cal.set(Calendar.YEAR, year);  
    cal.add(Calendar.DATE, -1);  
    cal.set(Calendar.DAY_OF_MONTH, 
    cal.getActualMaximum(Calendar.DAY_OF_MONTH));
    cal.set(Calendar.HOUR_OF_DAY, 0);
    cal.set(Calendar.MINUTE, 0);
    cal.set(Calendar.SECOND, 0);
    cal.set(Calendar.MILLISECOND, 0);
    return cal.getTimeInMillis();

Make your Activity like this.

public class MainActivity extends Activity {
WebView browser;

@Override
 protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    // find the WebView by name in the main.xml of step 2
    browser=(WebView)findViewById(R.id.wvwMain);

    // Enable javascript
    browser.getSettings().setJavaScriptEnabled(true);  

    // Set WebView client
    browser.setWebChromeClient(new WebChromeClient());

    browser.setWebViewClient(new WebViewClient() {

        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
                view.loadUrl(url);
                return true;
                }
        });
     // Load the webpage
    browser.loadUrl("http://google.com/");
   }
}

For me below worked:

Step 1: Downloaded and installed the web Installer exe from https://www.microsoft.com/en-us/download/details.aspx?id=48137 on the application server. Rebooted the application server after installation was completed.

Step 2: Added below changes in the web.config

<system.web>
    <compilation targetFramework="4.6"/> <!-- Changed framework 4.0 to 4.6 -->
    <!--Added this httpRuntime -->
    <httpRuntime targetFramework="4.6" />
</system.web>

Step 3: After completing step 1 and 2, it gave an error, "WebForms UnobtrusiveValidationMode requires a ScriptResourceMapping for 'jquery'. Please add a ScriptResourceMapping named jquery(case-sensitive)" and to resolve this error, I added below key in appsettings in my web.config file

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

Use the INTERVAL type to it. E.g:

--yesterday
SELECT NOW() - INTERVAL '1 DAY';

--Unrelated to the question, but PostgreSQL also supports some shortcuts:
SELECT 'yesterday'::TIMESTAMP, 'tomorrow'::TIMESTAMP, 'allballs'::TIME;

Then you can do the following on your query:

SELECT 
    org_id,
    count(accounts) AS COUNT,
    ((date_at) - INTERVAL '1 DAY') AS dateat
FROM 
    sourcetable
WHERE 
    date_at <= now() - INTERVAL '130 DAYS'
GROUP BY 
    org_id,
    dateat;

TIPS

Tip 1

You can append multiple operands. E.g.: how to get last day of current month?

SELECT date_trunc('MONTH', CURRENT_DATE) + INTERVAL '1 MONTH - 1 DAY';

Tip 2

You can also create an interval using make_interval function, useful when you need to create it at runtime (not using literals):

SELECT make_interval(days => 10 + 2);
SELECT make_interval(days => 1, hours => 2);
SELECT make_interval(0, 1, 0, 5, 0, 0, 0.0);

my approach was to use response.content (blob) and save to the file in binary mode

img_blob = requests.get(url, timeout=5).content
     with open(destination + '/' + title, 'wb') as img_file:
         img_file.write(img_blob)

You can create swap space using the following steps Here we are creating swap at /home/

1. dd if=/dev/zero of=/home/swapfile1 bs=1024 count=8388608
   Here count is kilobyte count of swap space

2. mkswap /home/swapfile1

3. vi /etc/fstab
   make entry :
   /home/swapfile1 swap swap defaults 0 0

4. run:
   swapon -a

Combine the SUBSTRING(), LEFT(), and CHARINDEX() functions.

SELECT LEFT(SUBSTRING(YOUR_FIELD,
                      CHARINDEX(';', YOUR_FIELD) + 1, 100),
                      CHARINDEX('[', YOUR_FIELD) - 1)
FROM YOUR_TABLE;

This assumes your field length will never exceed 100, but you can make it smarter to account for that if necessary by employing the LEN() function. I didn't bother since there's enough going on in there already, and I don't have an instance to test against, so I'm just eyeballing my parentheses, etc.

Adapted from CodeReview, here is a variant which works with num=1 !

from itertools import product
import operator

def prod(ls):
   return reduce(operator.mul, ls, 1)

def powered(factors, powers):
   return prod(f**p for (f,p) in zip(factors, powers))


def divisors(num) :

   pf = dict(prime_factors(num))
   primes = pf.keys()
   #For each prime, possible exponents
   exponents = [range(i+1) for i in pf.values()]
   return (powered(primes,es) for es in product(*exponents))

Long.valueOf(String s) - obviously due care must be taken to protect against non-numbers if that is possible in your code.

If the variable hasn't been declared, you wont be able to test for undefined using a function because you will get an error.

if (foo) {}
function (bar) {}(foo)

Both will generate an error if foo has not been declared.

If you want to test if a variable has been declared you can use

typeof foo != "undefined"

if you want to test if foo has been declared and it has a value you can use

if (typeof foo != "undefined" && foo) {
    //code here
}

With Linq...

string s = "7,true,NA,false:67,false,NA,false:5,false,NA,false:5,false,NA,false";
var count = s.Split(new[] {',', ':'}).Count(s => s == "true" );

if self.table:
    print 'It is not empty'

Is fine too

Would this help?

final List<String> l = new ArrayList<String>();
for (int i = 0; i < 10; i++) l.add("Number " + i);
for (int i = 0; i < 10; i++) System.out.println(l.get(i));

If you just want to see how your picture will look on the website without uploading it to the server or without running your website on a local server, I think a very simple solution will be to convert your picture into a Base64 and add the contents into an IMG tag or as a background-image with CSS.

Just to add, in case anyone else comes across this issue.

On a Mac I had to logout and log back in.

Then it prompts for username (NOTE: Not email) and password. (Need an account on https://hub.docker.com to pull images down)

Then it worked for me.

public String checkString(String value) {
    Stack<Character> stack = new Stack<>();
    char topStackChar = 0;
    for (int i = 0; i < value.length(); i++) {
        if (!stack.isEmpty()) {
            topStackChar = stack.peek();
        }
        stack.push(value.charAt(i));
        if (!stack.isEmpty() && stack.size() > 1) {
            if ((topStackChar == '[' && stack.peek() == ']') ||
                    (topStackChar == '{' && stack.peek() == '}') ||
                    (topStackChar == '(' && stack.peek() == ')')) {
                stack.pop();
                stack.pop();
            }
        }
    }
    return stack.isEmpty() ? "YES" : "NO";
}

The activity is declared NOT be recreated by rotation or keyboard slide.

Just got the same problem. Fix for API level 13 or higer.
From Android docs:

Note: If your application targets API level 13 or higher (as declared by the minSdkVersion and targetSdkVersion attributes), then you should also declare the "screenSize" configuration, because it also changes when a device switches between portrait and landscape orientations.

So i've changed my manifest to this:

<activity
        android:name="MyActivity"
        android:configChanges="orientation|screenSize"
        android:label="MyActivityName" >
</activity>

And now it works fine. Activity is not recreating when i rotate the phone, progress dialog and view stay the same. No error for me.

Use JSON to transfer data types (arrays and objects) between client and server.

In PHP:

• json_encode
• json_decode

In JavaScript:

• JSON.stringify
• JSON.parse

PHP:

echo json_encode($id_numbers);

JavaScript:

id_numbers = JSON.parse(msg);

As Wolfgang mentioned, you can give a fourth parameter to jQuery to automatically decode JSON for you.

id_numbers = new Array();
$.ajax({
    url:"Example.php",
    type:"POST",
    success:function(msg){
        id_numbers = msg;
    },
    dataType:"json"
});

You can connect two iPhones and transfer data via Bluetooth using either the high-level GameKit framework or the lower-level (but still easy to work with) Bonjour discovery mechanisms. Bonjour also works transparently between Bluetooth and WiFi on the iPhone under 3.0, so it's a good choice if you would like to support iPhone-to-iPhone data transfers on those two types of networks.

For more information, you can also look at the responses to these questions:

• "where can I find iphone sdk 3.0 GameKit tutorials for developing P2P applications?"
• "iPhone to iPhone networking"
• "GameKit in iPhone SDK 3.0"
• "Is iPhone bluetooth function limited in OS 3.0?"

To do this for oracle sql, the syntax would be:

,SUBSTR(col,INSTR(col,'-',1,2)+1) AS new_field

for this example, I look for the second '-' and take the substring to the end

If we are using TypeScript, we can update the type definition file by running the command npm install @types/node from the terminal or command prompt.

not sure how to do it all at once, but git git branch -d <branchname> will delete a local branch ONLY if it is completely merged. Note the lowercase d.

git branch -D <branchname> (note the capital D) will delete a local branch regardless of its merged status.

You can look into the regex module (the fuzzy section). I don't know if you can get the actual differences, but at least you can specify allowed number of different types of changes like insert, delete, and substitutions:

import regex
sequence = 'afrykanerskojezyczny'
queries = [ 'afrykanerskojezycznym', 'afrykanerskojezyczni', 
            'nieafrykanerskojezyczni' ]
for q in queries:
    m = regex.search(r'(%s){e<=2}'%q, sequence)
    print 'match' if m else 'nomatch'

Installing Hibernate Tools on Eclipse Neon (4.6)

Go to the menu Help > Install New Software and click the Add button.

Use something like JBoss Hibernate for the name and insert the following URL for the location:

http://download.jboss.org/jbosstools/neon/stable/updates/ 

Wait for the product tree to load and then expand the JBoss Web and Java EE Development folder and select the Hibernate Tools product and click the Next > button. Then follow on accepting all the subsequent questions, licence, etc.

When the installation is finished, restart Eclipse as required. After that, to open the Hibernate perspective go to the menu Window > Perspective > Open Perspective > Others and search for Hibernate.

Generally speaking, this is the pattern I use:

• HTTP GET - SELECT/Request
• HTTP PUT - UPDATE
• HTTP POST - INSERT/Create
• HTTP DELETE - DELETE

I recently ran into the same problem. Here is one thing to check. in visual studio there are three place we should check and remove the database.

1. Solution Explorer's App_Data folder
2. Server Explorer's Data Connection menu
3. SQL Server Object Explorer

When I delete database from the first two point, the error still occurs. So, I needed to delete the database from the SQL Server Object Explorer as well. Then I could easily run the 'update-database' command without error. Hope this helps.

Use preg_grep

$array = preg_grep(
    '/(my\n+string\n+)/i',
    array( 'file' , 'my string  => name', 'this')
);

You have a good example here (Array of Function pointers), with the syntax detailed.

int sum(int a, int b);
int subtract(int a, int b);
int mul(int a, int b);
int div(int a, int b);

int (*p[4]) (int x, int y);

int main(void)
{
  int result;
  int i, j, op;

  p[0] = sum; /* address of sum() */
  p[1] = subtract; /* address of subtract() */
  p[2] = mul; /* address of mul() */
  p[3] = div; /* address of div() */
[...]

To call one of those function pointers:

result = (*p[op]) (i, j); // op being the index of one of the four functions

You can use the following command:

 T instance = (T)typeof(T).GetConstructor(new Type[0]).Invoke(new object[0]);

Be sure to see the following reference.

They way I did it was by selecting all of the data

select * from myTable and then right-clicking on the result set and chose "Save results as..." a csv file.

Opening the csv file in Notepad++ I saw the LF characters not visible in SQL Server result set.

You can use below IsValidDate():

 public static bool IsValidDate(string value, string[] dateFormats)
    {
        DateTime tempDate;
        bool validDate = DateTime.TryParseExact(value, dateFormats, DateTimeFormatInfo.InvariantInfo, DateTimeStyles.None, ref tempDate);
        if (validDate)
            return true;
        else
            return false;
    }

And you can pass in the value and date formats. For example:

var data = "02-08-2019";
var dateFormats = {"dd.MM.yyyy", "dd-MM-yyyy", "dd/MM/yyyy"}

if (IsValidDate(data, dateFormats))
{
    //Do something
}
else
{
    //Do something else
}

If you want to keep it open when you are debugging, but still let it close normally when not debugging, you can do something like this:

if (System.Diagnostics.Debugger.IsAttached) Console.ReadLine();

Like other answers have stated, the call to Console.ReadLine() will keep the window open until enter is pressed, but Console.ReadLine() will only be called if the debugger is attached.

This totally caught me off guard recently. This is because I've programmed in C since the 1970's and I'm only now learning the fine details of Python. Like this curious behavior of math.floor().

The math library of Python is how you access the C standard math library. And the C standard math library is a collection of floating point numerical functions, like sin(), and cos(), sqrt(). The floor() function in the context of numerical calculations has ALWAYS returned a float. For 50 YEARS now. It's part of the standards for numerical computation. For those of us familiar with the math library of C, we don't understand it to be just "math functions". We understand it to be a collection of floating-point algorithms. It would be better named something like NFPAL - Numerical Floating Point Algorithms Libary. :)

Those of us that understand the history instantly see the python math module as just a wrapper for the long-established C floating-point library. So we expect without a second thought, that math.floor() is the same function as the C standard library floor() which takes a float argument and returns a float value.

The use of floor() as a numerical math concept goes back to 1798 per the Wikipedia page on the subject: https://en.wikipedia.org/wiki/Floor_and_ceiling_functions#Notation

It never has been a computer science covert floating-point to integer storage format function even though logically it's a similar concept.

The floor() function in this context has always been a floating-point numerical calculation as all(most) the functions in the math library. Floating-point goes beyond what integers can do. They include the special values of +inf, -inf, and Nan (not a number) which are all well defined as to how they propagate through floating-point numerical calculations. Floor() has always CORRECTLY preserved values like Nan and +inf and -inf in numerical calculations. If Floor returns an int, it totally breaks the entire concept of what the numerical floor() function was meant to do. math.floor(float("nan")) must return "nan" if it is to be a true floating-point numerical floor() function.

When I recently saw a Python education video telling us to use:

i = math.floor(12.34/3)

to get an integer I laughed to myself at how clueless the instructor was. But before writing a snarkish comment, I did some testing and to my shock, I found the numerical algorithms library in Python was returning an int. And even stranger, what I thought was the obvious answer to getting an int from a divide, was to use:

i = 12.34 // 3

Why not use the built-in integer divide to get the integer you are looking for! From my C background, it was the obvious right answer. But low and behold, integer divide in Python returns a FLOAT in this case! Wow! What a strange upside-down world Python can be.

A better answer in Python is that if you really NEED an int type, you should just be explicit and ask for int in python:

i = int(12.34/3)

Keeping in mind however that floor() rounds towards negative infinity and int() rounds towards zero so they give different answers for negative numbers. So if negative values are possible, you must use the function that gives the results you need for your application.

Python however is a different beast for good reasons. It's trying to address a different problem set than C. The static typing of Python is great for fast prototyping and development, but it can create some very complex and hard to find bugs when code that was tested with one type of objects, like floats, fails in subtle and hard to find ways when passed an int argument. And because of this, a lot of interesting choices were made for Python that put the need to minimize surprise errors above other historic norms.

Changing the divide to always return a float (or some form of non int) was a move in the right direction for this. And in this same light, it's logical to make // be a floor(a/b) function, and not an "int divide".

Making float divide by zero a fatal error instead of returning float("inf") is likewise wise because, in MOST python code, a divide by zero is not a numerical calculation but a programming bug where the math is wrong or there is an off by one error. It's more important for average Python code to catch that bug when it happens, instead of propagating a hidden error in the form of an "inf" which causes a blow-up miles away from the actual bug.

And as long as the rest of the language is doing a good job of casting ints to floats when needed, such as in divide, or math.sqrt(), it's logical to have math.floor() return an int, because if it is needed as a float later, it will be converted correctly back to a float. And if the programmer needed an int, well then the function gave them what they needed. math.floor(a/b) and a//b should act the same way, but the fact that they don't I guess is just a matter of history not yet adjusted for consistency. And maybe too hard to "fix" due to backward compatibility issues. And maybe not that important???

In Python, if you want to write hard-core numerical algorithms, the correct answer is to use NumPy and SciPy, not the built-in Python math module.

import numpy as np

nan = np.float64(0.0) / 0.0    # gives a warning and returns float64 nan

nan = np.floor(nan)            # returns float64 nan

Python is different, for good reasons, and it takes a bit of time to understand it. And we can see in this case, the OP, who didn't understand the history of the numerical floor() function, needed and expected it to return an int from their thinking about mathematical integers and reals. Now Python is doing what our mathematical (vs computer science) training implies. Which makes it more likely to do what a beginner expects it to do while still covering all the more complex needs of advanced numerical algorithms with NumPy and SciPy. I'm constantly impressed with how Python has evolved, even if at times I'm totally caught off guard.

var logger = require('nodejslogger')
logger.init({"file":"output-file", "mode":"DIE"})

D : Debug, I : Info, E : Error

logger.debug("Debug logs")
logger.info("Info logs")
logger.error("Error logs")

The module can be accessed at : https://www.npmjs.com/package/nodejslogger

add setOnItemSelectedListener to spinner reference and get the data like that`

 mSizeSpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<?> adapterView, View view, int position, long l) {
            selectedSize=adapterView.getItemAtPosition(position).toString();

From SQLServer 2012 more elegant alter role:

I'm pretty sure those are warnings, not errors. Your project should still run just fine.

However, since you should always try to fix compiler warnings, let's see what we can discover. I'm not at all familiar with OpenCV, and you don't link to the wiki tutorial that you're following. But it looks to me like the problem is that you're running a 64-bit version of Windows (as evidenced by the "SysWOW64" folder in the path to the DLL files), but the OpenCV stuff that you're trying is built for a 32-bit platform. So you might need to rebuild the project using CMake, as explained here.

More specifically, the files that are listed are Windows system files. PDB files contain debugging information that Visual Studio uses to allow you to step into and debug compiled code. You don't actually need the PDB files for system libraries to be able to debug your own code. But if you want, you can download the symbols for the system libraries as well. Go to the "Debug" menu, click on "Options and Settings", and scroll down the listbox on the right until you see "Enable source server support". Make sure that option is checked. Then, in the treeview to the left, click on "Symbols", and make sure that the "Microsoft Symbol Servers" option is selected. Click OK to dismiss the dialog, and then try rebuilding.

In HTML, elements containing nothing but normal whitespace characters are considered empty. A paragraph that contains just a normal space character will have zero height. A non-breaking space is a special kind of whitespace character that isn't considered to be insignificant, so it can be used as content for a non-empty paragraph.

Even if you consider CSS margins on paragraphs, since an "empty" paragraph has zero height, its vertical margins will collapse. This causes it to have no height and no margins, making it appear as if it were never there at all.

I have done this using this method

save the id in some variable

var someVariable = document.getElementById("someId");

then use if condition

if(someVariable === ""){
 //logic
} else if(someVariable !== ""){
 //logic
}

you can easily find the current CodeIgniter version by

echo CI_VERSION 


or you can navigate to System->core->codeigniter.php file and you can see the constant

/**
 * CodeIgniter Version
 *
 * @var string
 *
 */
    const CI_VERSION = '3.1.6';

Date has the time as well, just add HH:mm:ss to the date format:

import java.text.SimpleDateFormat
def date = new Date()
def sdf = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss")
println sdf.format(date)

In case you are using JRE 8 you can use LoaclDateTime:

import java.time.*

LocalDateTime t = LocalDateTime.now();
return t as String

<asp:TextBox ID="txtMobile" runat="server" CssClass="form-control" style="width:92%;  margin:0px 5px 0px 5px;" onkeypress="javascript:return isNumberKey(event);" MaxLength="12"></asp:TextBox>

<script>
    function isNumberKey(evt) {
        var charCode = (evt.which) ? evt.which : event.keyCode;
        if (charCode > 31 && (charCode < 48 || charCode > 57)) {
            return false;
        }
        return true;
    }
</script>

Check this answer: Set CORS header in Tomcat

Note that you need Tomcat 7.0.41 or higher.

To know where the current instance of Tomcat is located try this:

System.out.println(System.getProperty("catalina.base"));

You'll see the path in the console view.

Then look for /conf/web.xml on that folder, open it and add the lines of the above link.

This is how I solved this problem. This way, EF knows which to add which to update.

We also ran into this error on a new Apache server build.

The fix in our case was to define a ServerAlias in the httpd.conf that corresponded to the host name that Java was trying to connect to. Our ServerName was set to the internal host name. Our SSL cert was using the external host name, but that was not sufficient to avoid the warning.

To help debug, you can use this ssl command:

openssl s_client -servername <hostname> -connect <hostname>:443 -state

If there is a problem with that hostname, then it will print this message near the top of the output:

SSL3 alert read: warning:unrecognized name

I should also note that we did not get that error when using that command to connect to the internal host name, even though it did not match the SSL cert.

Brad Wilson has a couple great articles on unobtrusive validation and unobtrusive ajax.
It is also shown very nicely in this Pluralsight video in the section on " AJAX and JavaScript".

Basically, it is simply Javascript validation that doesn't pollute your source code with its own validation code. This is done by making use of data- attributes in HTML.

Is something like this what you want to do?

$return_arr = array();

$fetch = mysql_query("SELECT * FROM table"); 

while ($row = mysql_fetch_array($fetch, MYSQL_ASSOC)) {
    $row_array['id'] = $row['id'];
    $row_array['col1'] = $row['col1'];
    $row_array['col2'] = $row['col2'];

    array_push($return_arr,$row_array);
}

echo json_encode($return_arr);

It returns a json string in this format:

[{"id":"1","col1":"col1_value","col2":"col2_value"},{"id":"2","col1":"col1_value","col2":"col2_value"}]

OR something like this:

$year = date('Y');
$month = date('m');

$json_array = array(

//Each array below must be pulled from database
    //1st record
    array(
    'id' => 111,
    'title' => "Event1",
    'start' => "$year-$month-10",
    'url' => "http://yahoo.com/"
),

     //2nd record
     array(
    'id' => 222,
    'title' => "Event2",
    'start' => "$year-$month-20",
    'end' => "$year-$month-22",
    'url' => "http://yahoo.com/"
)

);

echo json_encode($json_array);

Attribute_Brands is a named range that should contain your list items. Use the drop down to the left of the formula bar to jump to the named range, then edit it. If you add or remove items you will need to adjust the range the named range covers.

I was also facing the same problem. To fix this to the following steps.

1. open Javaws from cmd runnig javaws -viewer command. A new window will open
2. Select the jnlp file which you want and click the run button.
3. Close the javaws viewer window.

Use this to obtain only the filename.

Path.GetFileName(files[0]);

A period is used to concatenate strings. Simple example to turn two string variables into a single variable:

$full = $part1 . $part2;

In your example, you'd want to do:

$result = $data1 . ' ' . $data2;

You'll notice I added a string of one space between the two variables. This is because your original $data1 did not end with a space. If you had combined them without it, your $result variable would end up looking like the color isred.

I think there is some confusion about the difference between MVC and Web Api. In short, for MVC you can use a login form and create a session using cookies. For Web Api there is no session. That's why you want to use the token.

You do not need a login form. The Token endpoint is all you need. Like Win described you'll send the credentials to the token endpoint where it is handled.

Here's some client side C# code to get a token:

    //using System;
    //using System.Collections.Generic;
    //using System.Net;
    //using System.Net.Http;
    //string token = GetToken("https://localhost:<port>/", userName, password);

    static string GetToken(string url, string userName, string password) {
        var pairs = new List<KeyValuePair<string, string>>
                    {
                        new KeyValuePair<string, string>( "grant_type", "password" ), 
                        new KeyValuePair<string, string>( "username", userName ), 
                        new KeyValuePair<string, string> ( "Password", password )
                    };
        var content = new FormUrlEncodedContent(pairs);
        ServicePointManager.ServerCertificateValidationCallback += (sender, cert, chain, sslPolicyErrors) => true;
        using (var client = new HttpClient()) {
            var response = client.PostAsync(url + "Token", content).Result;
            return response.Content.ReadAsStringAsync().Result;
        }
    }

In order to use the token add it to the header of the request:

    //using System;
    //using System.Collections.Generic;
    //using System.Net;
    //using System.Net.Http;
    //var result = CallApi("https://localhost:<port>/something", token);

    static string CallApi(string url, string token) {
        ServicePointManager.ServerCertificateValidationCallback += (sender, cert, chain, sslPolicyErrors) => true;
        using (var client = new HttpClient()) {
            if (!string.IsNullOrWhiteSpace(token)) {
                var t = JsonConvert.DeserializeObject<Token>(token);

                client.DefaultRequestHeaders.Clear();
                client.DefaultRequestHeaders.Add("Authorization", "Bearer " + t.access_token);
            }
            var response = client.GetAsync(url).Result;
            return response.Content.ReadAsStringAsync().Result;
        }
    }

Where Token is:

//using Newtonsoft.Json;

class Token
{
    public string access_token { get; set; }
    public string token_type { get; set; }
    public int expires_in { get; set; }
    public string userName { get; set; }
    [JsonProperty(".issued")]
    public string issued { get; set; }
    [JsonProperty(".expires")]
    public string expires { get; set; }
}

Now for the server side:

In Startup.Auth.cs

        var oAuthOptions = new OAuthAuthorizationServerOptions
        {
            TokenEndpointPath = new PathString("/Token"),
            Provider = new ApplicationOAuthProvider("self"),
            AccessTokenExpireTimeSpan = TimeSpan.FromDays(14),
            // https
            AllowInsecureHttp = false
        };
        // Enable the application to use bearer tokens to authenticate users
        app.UseOAuthBearerTokens(oAuthOptions);

And in ApplicationOAuthProvider.cs the code that actually grants or denies access:

//using Microsoft.AspNet.Identity.Owin;
//using Microsoft.Owin.Security;
//using Microsoft.Owin.Security.OAuth;
//using System;
//using System.Collections.Generic;
//using System.Security.Claims;
//using System.Threading.Tasks;

public class ApplicationOAuthProvider : OAuthAuthorizationServerProvider
{
    private readonly string _publicClientId;

    public ApplicationOAuthProvider(string publicClientId)
    {
        if (publicClientId == null)
            throw new ArgumentNullException("publicClientId");

        _publicClientId = publicClientId;
    }

    public override async Task GrantResourceOwnerCredentials(OAuthGrantResourceOwnerCredentialsContext context)
    {
        var userManager = context.OwinContext.GetUserManager<ApplicationUserManager>();

        var user = await userManager.FindAsync(context.UserName, context.Password);
        if (user == null)
        {
            context.SetError("invalid_grant", "The user name or password is incorrect.");
            return;
        }

        ClaimsIdentity oAuthIdentity = await user.GenerateUserIdentityAsync(userManager);
        var propertyDictionary = new Dictionary<string, string> { { "userName", user.UserName } };
        var properties = new AuthenticationProperties(propertyDictionary);

        AuthenticationTicket ticket = new AuthenticationTicket(oAuthIdentity, properties);
        // Token is validated.
        context.Validated(ticket);
    }

    public override Task TokenEndpoint(OAuthTokenEndpointContext context)
    {
        foreach (KeyValuePair<string, string> property in context.Properties.Dictionary)
        {
            context.AdditionalResponseParameters.Add(property.Key, property.Value);
        }
        return Task.FromResult<object>(null);
    }

    public override Task ValidateClientAuthentication(OAuthValidateClientAuthenticationContext context)
    {
        // Resource owner password credentials does not provide a client ID.
        if (context.ClientId == null)
            context.Validated();

        return Task.FromResult<object>(null);
    }

    public override Task ValidateClientRedirectUri(OAuthValidateClientRedirectUriContext context)
    {
        if (context.ClientId == _publicClientId)
        {
            var expectedRootUri = new Uri(context.Request.Uri, "/");

            if (expectedRootUri.AbsoluteUri == context.RedirectUri)
                context.Validated();
        }
        return Task.FromResult<object>(null);
    }

}

As you can see there is no controller involved in retrieving the token. In fact, you can remove all MVC references if you want a Web Api only. I have simplified the server side code to make it more readable. You can add code to upgrade the security.

Make sure you use SSL only. Implement the RequireHttpsAttribute to force this.

You can use the Authorize / AllowAnonymous attributes to secure your Web Api. Additionally you can add filters (like RequireHttpsAttribute) to make your Web Api more secure. I hope this helps.

if you use the "Task List" view of Eclipse, it will sometimes try to hide files or projects that it thinks are not associated with a given task (i.e. any file that was not opened while you had a certain task selected as the current task). If you want Eclipse to stop hiding files in that case, you can just delete all tasks.

Or you may also restart your eclipse and by just closing the project and then opening it again (from the right mouse click context menu) the files will be restored.

If that doesnt get your projects back then check the "filters option" (Click on right corner of Project Explorer tab and open context menu. Select Filters option from menu) and make sure that your projects type isnt checked.

Also, if you don't have the gradlew file in your current directory:

You can install gradle with homebrew with the following command:

$ brew install gradle

As mentioned in this answer. Then, you are not going to need to include it in your path (homebrew will take care of that) and you can just run (from any directory):

$ gradle test 

Just to complete this with the most stupid method I can come up with: Generate all possible strings of length 1, use equals to compare them to the original string; if they are equal, the string length is 1. If no string matches, generate all possible strings of length 2, compare them, for string length 2. Etc. Continue until you find the string length or the universe ends, whatever happens first.

The second way is a tad more efficient, but a much better way is to execute them in batches:

public void executeBatch(List<Entity> entities) throws SQLException { 
    try (
        Connection connection = dataSource.getConnection();
        PreparedStatement statement = connection.prepareStatement(SQL);
    ) {
        for (Entity entity : entities) {
            statement.setObject(1, entity.getSomeProperty());
            // ...

            statement.addBatch();
        }

        statement.executeBatch();
    }
}

You're however dependent on the JDBC driver implementation how many batches you could execute at once. You may for example want to execute them every 1000 batches:

public void executeBatch(List<Entity> entities) throws SQLException { 
    try (
        Connection connection = dataSource.getConnection();
        PreparedStatement statement = connection.prepareStatement(SQL);
    ) {
        int i = 0;

        for (Entity entity : entities) {
            statement.setObject(1, entity.getSomeProperty());
            // ...

            statement.addBatch();
            i++;

            if (i % 1000 == 0 || i == entities.size()) {
                statement.executeBatch(); // Execute every 1000 items.
            }
        }
    }
}

As to the multithreaded environments, you don't need to worry about this if you acquire and close the connection and the statement in the shortest possible scope inside the same method block according the normal JDBC idiom using try-with-resources statement as shown in above snippets.

If those batches are transactional, then you'd like to turn off autocommit of the connection and only commit the transaction when all batches are finished. Otherwise it may result in a dirty database when the first bunch of batches succeeded and the later not.

public void executeBatch(List<Entity> entities) throws SQLException { 
    try (Connection connection = dataSource.getConnection()) {
        connection.setAutoCommit(false);

        try (PreparedStatement statement = connection.prepareStatement(SQL)) {
            // ...

            try {
                connection.commit();
            } catch (SQLException e) {
                connection.rollback();
                throw e;
            }
        }
    }
}

The two commands are equivalent.

There are lot of different Timers in the .NET BCL:

• System.Timers.Timer
• System.Threading.Timer
• System.Windows.Forms.Timer
• System.Web.UI.Timer
• System.Windows.Threading.DispatcherTimer

When to use which?

• System.Timers.Timer, which fires an event and executes the code in one or more event sinks at regular intervals. The class is intended for use as a server-based or service component in a multithreaded environment; it has no user interface and is not visible at runtime.
• System.Threading.Timer, which executes a single callback method on a thread pool thread at regular intervals. The callback method is defined when the timer is instantiated and cannot be changed. Like the System.Timers.Timer class, this class is intended for use as a server-based or service component in a multithreaded environment; it has no user interface and is not visible at runtime.
• System.Windows.Forms.Timer (.NET Framework only), a Windows Forms component that fires an event and executes the code in one or more event sinks at regular intervals. The component has no user interface and is designed for use in a single-threaded environment; it executes on the UI thread.
• System.Web.UI.Timer (.NET Framework only), an ASP.NET component that performs asynchronous or synchronous web page postbacks at a regular interval.
• System.Windows.Threading.DispatcherTimer, a timer that's integrated into the Dispatcher queue. This timer is processed with a specified priority at a specified time interval.

Source

Some of them needs explicit Start call to begin ticking (for example System.Timers, System.Windows.Forms). And an explicit Stop to finish ticking.

using TimersTimer = System.Timers.Timer;

static void Main(string[] args)
{
    var timer = new TimersTimer(1000);
    timer.Elapsed += (s, e) => Console.WriteLine("Beep");
    Thread.Sleep(1000); //1 second delay
    timer.Start();
    Console.ReadLine();
    timer.Stop();

}

While on the other hand there are some Timers (like: System.Threading) where you don't need explicit Start and Stop calls. (The provided delegate will run a background thread.) Your timer will tick until you or the runtime dispose it.

So, the following two versions will work in the same way:

using ThreadingTimer = System.Threading.Timer;

static void Main(string[] args)
{
    var timer = new ThreadingTimer(_ => Console.WriteLine("Beep"), null, TimeSpan.FromSeconds(1), TimeSpan.FromSeconds(1));
    Console.ReadLine();
}

using ThreadingTimer = System.Threading.Timer;
static void Main(string[] args)
{
    StartTimer();
    Console.ReadLine();
}

static void StartTimer()
{
    var timer = new ThreadingTimer(_ => Console.WriteLine("Beep"), null, TimeSpan.FromSeconds(1), TimeSpan.FromSeconds(1));
}

But if your timer disposed then it will stop ticking obviously.

using ThreadingTimer = System.Threading.Timer; 

static void Main(string[] args)
{
    StartTimer();
    GC.Collect(0);
    Console.ReadLine();
}

static void StartTimer()
{
    var timer = new ThreadingTimer(_ => Console.WriteLine("Beep"), null, TimeSpan.FromSeconds(1), TimeSpan.FromSeconds(1));
}

When you want to convert your code to result( executable, library or whatever ), there is 2 steps:
1) compile
2) link
In first step compiler should now about some things like sizeof objects that used by you, prototype of functions and maybe inheritance. on the other hand linker want to find implementation of functions and global variables in your code.

Now when you use ClassTwo in File1.cpp compiler know nothing about it and don't know how much memory should allocate for it or for example witch members it have or is it a class and enum or even a typedef of int, so compilation will be failed by the compiler. adding File2.cpp solve the problem of linker that look for implementation but the compiler is still unhappy, because it know nothing about your type.

So remember, in compile phase you always work with just one file( and of course files that included by that one file ) and in link phase you need multiple files that contain implementations. and since C/C++ are statically typed and they allow their identifier to work for many purposes( definition, typedef, enum class, ... ) so you should always identify you identifier to the compiler and then use it and as a rule compiler should always know size of your variable!!

You can easily iterate over your view controllers if you are using a navigation controller. And then you can check for the particular instance as:
Swift 5

 if let viewControllers = navigationController?.viewControllers {
            for viewController in viewControllers {
                if viewController.isKind(of: LoginViewController.self) {
                    
                }
            }
        }

You need to make the changes in the binding configuration (in the app.config file) on the SERVER and the CLIENT, or it will not take effect.

<system.serviceModel>
    <bindings>
        <basicHttpBinding>
            <binding maxReceivedMessageSize="2147483647 " max...=... />
        </basicHttpBinding>
       </bindings>
</system.serviceModel>

Implementations of java.util.Set

Create a block using

 #define MACRO(...) do { ... } while(false)

Do not add a ; after the while(false)

Drag the constraint into your VC as an IBOutlet. Then you can change its associated value (and other properties; check the documentation):

@IBOutlet myConstraint : NSLayoutConstraint!
@IBOutlet myView : UIView!

func updateConstraints() {
    // You should handle UI updates on the main queue, whenever possible
    DispatchQueue.main.async {
        self.myConstraint.constant = 10
        self.myView.layoutIfNeeded()
    }
}

My problem was that POST requests need trailing slashes '/'.

Please try:

SELECT * INTO NewTable FROM OldTable

To convert String into Int

var numberA = Int("10")

Print(numberA) // It will print 10

To covert Int into String

var numberA = 10

1st way)

print("numberA is \(numberA)") // It will print 10

2nd way)

var strSomeNumber = String(numberA)

or

var strSomeNumber = "\(numberA)"

C# generally uses xml-based config files rather than the *.ini-style file like you said, so there's nothing built-in to handle this. However, google returns a number of promising results.

I think the best way is to use currentTarget property instead of target property.

The currentTarget read-only property of the Event interface identifies the current target for the event, as the event traverses the DOM. It always refers to the element to which the event handler has been attached, as opposed to Event.target, which identifies the element on which the event occurred.

For example:

<a href="#"><span class="icon"></span> blah blah</a>

Javascript:

a.addEventListener('click', e => {
    e.currentTarget; // always returns "a" element
    e.target; // may return "a" or "span"
})

This is just a wrap up of Sayan Pal answer in a shorter form, ES5 style :

var Foo = function(){
    this.bar = undefined;
    this.buzz = undefined;
}

var foo = Object.assign(new Foo(),{
    bar: "whatever",
    buzz: "something else"
});

I like it because it is the closest to the very neat object initialisation in .Net:

var foo = new Foo()
{
    bar: "whatever",
    ...

For dependency

<dependency>
    <groupId>com.oracle</groupId>
    <artifactId>ojdbc7</artifactId>
    <version>12.1.0.2</version>
</dependency>

Try

<repository>
    <id>mvnrepository</id>
    <url>http://nexus.saas.hand-china.com/content/repositories/rdc</url>
</repository>

<?php
$names = array("firstname"=>"maurice",
               "lastname"=>"muteti", 
               "contact"=>"7844433339");

foreach ($names as $name => $value) {
    echo $name." ".$value."</br>";
}

print_r($names);
?>

You can use the fact that Python concatenates string literals which appear adjacent to each other:

>>> def fun():
...     print '{0} Here is a really long ' \
...           'sentence with {1}'.format(3, 5)

I couldn't find solution for other browsers. When I posted this question, IE was on the higher priority and gladly I found one for it. If you have a solution for other browsers (firefox, safari, opera) please do share here. Thanks.

VBSCRIPT is much more convenient than creating an ActiveX on VB6 or C#/VB.NET:

<script language='VBScript'>
Sub Print()
       OLECMDID_PRINT = 6
       OLECMDEXECOPT_DONTPROMPTUSER = 2
       OLECMDEXECOPT_PROMPTUSER = 1
       call WB.ExecWB(OLECMDID_PRINT, OLECMDEXECOPT_DONTPROMPTUSER,1)
End Sub
document.write "<object ID='WB' WIDTH=0 HEIGHT=0 CLASSID='CLSID:8856F961-340A-11D0-A96B-00C04FD705A2'></object>"
</script>

Now, calling:

<a href="javascript:window.print();">Print</a>

will send print without popup print window.

Here's an example using Guzzle:

/**
 * @param string $accessToken JSON-encoded access token as returned by \Google_Client->getAccessToken() or raw access token
 * @return array|false False if token is invalid or array in the form
 * 
 * array (
 *   'issued_to' => 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.apps.googleusercontent.com',
 *   'audience' => 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.apps.googleusercontent.com',
 *   'scope' => 'https://www.googleapis.com/auth/calendar',
 *   'expires_in' => 3350,
 *   'access_type' => 'offline',
 * )
 */
public static function tokenInfo($accessToken) {
    if(!strlen($accessToken)) {
        return false;
    }

    if($accessToken[0] === '{') {
        $accessToken = json_decode($accessToken)->access_token;
    }

    $guzzle = new \GuzzleHttp\Client();

    try {
        $resp = $guzzle->get('https://www.googleapis.com/oauth2/v1/tokeninfo', [
            'query' => ['access_token' => $accessToken],
        ]);
    } catch(ClientException $ex) {
        return false;
    }

    return $resp->json();
}

have a try with Flex Paper http://flexpaper.devaldi.com/

it works like scribd

You can:

o Set .kundregister_grid_1 to:

• width(or width-min) with height (or min-height)
• or padding-top
• or padding-bottom
• or border-top
• or border-bottom

o Or use pseudo-elements: ::before or ::after with:

• {content: "\200B";}
• or {content: "."; visibility: hidden;}.

o Or put   inside empty element, but this sometimes can bring unexpected effects eg. in combination with text-decoration: underline;

window.location is read/write on all compliant browsers.

document.location is read-only in Internet Explorer (at least), but read/write in Gecko-based browsers (Firefox, SeaMonkey).

If you use spring this a better way

Is there any way to create form with multiple submit buttons on Spring MVC using annotations?

Apply: s/^\s*//; s/\s+$//; to it. Or use s/^\s+|\s+$//g if you want to be fancy.

Following function will return a key-value pair of the required cookie, where key is the cookie name and value will be the value of the cookie.

/**
 * Returns cookie key-value pair
 */
var getCookieByName = function(name) {
    var result = ['-1','-1'];
    if(name) {
        var cookieList = document.cookie.split(';');
        result = $.grep(cookieList,function(cookie) { 
            cookie = cookie.split('=')[0];
            return cookie == name;
        });
    }
    return result;
};

Generally there are two ways to do it, a converter class or a property in the Viewmodel that essentially converts the value for you.

I tend to use the property approach if it is a one off conversion. If you want to reuse it, use the converter. Below, find an example of the converter:

<ValueConversion(GetType(Boolean), GetType(Visibility))> _
Public Class BoolToVisibilityConverter
    Implements IValueConverter

    Public Function Convert(ByVal value As Object, ByVal targetType As System.Type, ByVal parameter As Object, ByVal culture As System.Globalization.CultureInfo) As Object Implements System.Windows.Data.IValueConverter.Convert

        If value IsNot Nothing Then
            If value = True Then 
                Return Visibility.Visible
            Else
                Return Visibility.Collapsed
            End If
        Else
            Return Visibility.Collapsed
        End If
    End Function

    Public Function ConvertBack(ByVal value As Object, ByVal targetType As System.Type, ByVal parameter As Object, ByVal culture As System.Globalization.CultureInfo) As Object Implements System.Windows.Data.IValueConverter.ConvertBack
        Throw New NotImplementedException
    End Function
End Class

A ViewModel property method would just check the boolean property value, and return a visibility based on that. Be sure to implement INotifyPropertyChanged and call it on both the Boolean and Visibility properties to updated properly.

It's possible to manually trigger events like this:

Apply the slider behavior to the element

var s = $('#slider').slider();

...

Set the slider value

s.slider('value',10);

Trigger the slide event, passing a ui object

s.trigger('slide',{ ui: $('.ui-slider-handle', s), value: 10 });

I will just add a blank ("") to the end of the variable and do the comparison. Something like below should work even when that variable is null. You can also trim the variable just in case of spaces.

If provider & "" <> "" Then 
    url = url & "&provider=" & provider 
End if

TLDR for people comming from c++

It's just overloaded operator of ( ) parentheses

So in scala:

class X {
   def apply(param1: Int, param2: Int, param3: Int) : Int = {
     // Do something
   }
}

Is same as this in c++:

class X {
   int operator()(int param1, int param2, int param3) {
      // do something
   }
};

In my case the reason of the error is library which was linked two times.

I use react-native so it was linked automatically using react-native link and manually in xcode.

I summarize the answers found in that article:

http://www.quora.com/How-does-MongoDB-compare-to-CouchDB-What-are-the-advantages-and-disadvantages-of-each

MongoDB: Better querying, data storage in BSON (faster access), better data consistency, multiple collections

CouchDB: Better replication, with master to master replication and conflict resolution, data storage in JSON (human-readable, better access through REST services), querying through map-reduce.

So in conclusion, MongoDB is faster, CouchDB is safer.

Also: http://nosql.mypopescu.com/post/298557551/couchdb-vs-mongodb

As the error states - the database is not open - it was previously shut down, and someone left it in the middle of the startup process. They may either be intentional, or unintentional (i.e., it was supposed to be open, but failed to do so).

Assuming that's nothing wrong with the database itself, you could open it with a simple statement:(Since the question is asked specifically in the context of SQLPlus, kindly remember to put a statement terminator(Semicolon) at the end mandatorily, otherwise, it will result in an error.)

ALTER DATABASE OPEN;

The StreamReader class's constructor takes a 'detect encoding' parameter.

Normal way is to:

float f = 3.4;
int n = static_cast<int>(f);

You can do these in unix shell:

java -cp MyJar.jar:lib/* com.somepackage.subpackage.Main

You can do these in windows powershell:

java -cp "MyJar.jar;lib\*" com.somepackage.subpackage.Main

The presence of the n option attached to the -k5 causes the global -r option to be ignored for that field. You have to specify both n and r at the same level (globally or locally).

sort -t $'\t' -k5,5rn

or

sort -rn -t $'\t' -k5,5

Combine @vincsilver and @jdigital's answers with some modifications,

1. export .reg to current directory
2. add date mark

code:

set TODAY=%DATE:~0,4%-%DATE:~5,2%-%DATE:~8,2%

regedit /e "%CD%\user_env_variables[%TODAY%].reg" "HKEY_CURRENT_USER\Environment"
regedit /e "%CD%\global_env_variables[%TODAY%].reg" "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment"

Output would like:

global_env_variables[2017-02-14].reg
user_env_variables[2017-02-14].reg

Download the appropriate APR based tomcat native library for your operating system so that Apache tomcat server can take some advantage of the feature of your OS which is not included by default in tomcat. For windows it will be a .dll file.

I too got the warning while starting the server and you don't have to worry about this if you are testing or developing. This is meant to be on production purposes. After putting the tcnative-1.dll file inside the bin folder of Apache Tomcat 7 following are the output in the stderr file,

json_encode is available in php > 5.2.0:

echojson_encode($row);

The following solution is specifically for wamp environments:

This foxed me for a little while, tried all the other suggestions, $PATH etc even searched the windows registry looking for clues:

The GUI (wampmanager) indicates I have version 7 selected and yes if I phpinfo() in a page in the browser it will tell me its version 7.x.x yet php -v in the command prompt reports a 5.x.x

If you right click on the wampmanager head to icon->tools->delete unused versions and remove the old version, let it restart the services then the command prompt will return a 7.x.x

This solution means you no longer have the old version if you want to switch between php versions but there is a configuration file in C:\wamp64\wampmanager.conf which appears to specify the version to use with CLI (the parameter is called phpCliVersion). I changed it, restarted the server ... thought I had solved it but no effect perhaps I was a little impatient so I have a feeling there may be some mileage in that.

Hope that helps someone

I am using Windows 8 and found the missing scripts in the path below:

C:\Users\YourUsername\Documents\SQL Server Management Studio\Backup Files

There are two options to handle/avoid this situation.

1. Before re-running the application just terminate the previous connection.

• Open the console --> right click --> terminate all.

2. If you forgot to perform action mention on step 1 then

• Figure out the port used by your application, you could see it the stack trace in the console window
• Figure out the process id associated to port by executing netstat -aon command in cmd
• Kill that process and re-run the application.

A big difference is if you are displaying arrays. Especially ones with NIL. For example:

print [nil, 1, 2]

gives

[nil, 1, 2]

but

puts [nil, 1, 2]

gives

1
2

Note, no appearing nil item (just a blank line) and each item on a different line.

You must manually clear the ChildItems collection and append new items into it:

thisParent.ChildItems.Clear();
thisParent.ChildItems.AddRange(modifiedParent.ChildItems);

After that you can call DeleteOrphans extension method which will handle with orphaned entities (it must be called between DetectChanges and SaveChanges methods).

public static class DbContextExtensions
{
    private static readonly ConcurrentDictionary< EntityType, ReadOnlyDictionary< string, NavigationProperty>> s_navPropMappings = new ConcurrentDictionary< EntityType, ReadOnlyDictionary< string, NavigationProperty>>();

    public static void DeleteOrphans( this DbContext source )
    {
        var context = ((IObjectContextAdapter)source).ObjectContext;
        foreach (var entry in context.ObjectStateManager.GetObjectStateEntries(EntityState.Modified))
        {
            var entityType = entry.EntitySet.ElementType as EntityType;
            if (entityType == null)
                continue;

            var navPropMap = s_navPropMappings.GetOrAdd(entityType, CreateNavigationPropertyMap);
            var props = entry.GetModifiedProperties().ToArray();
            foreach (var prop in props)
            {
                NavigationProperty navProp;
                if (!navPropMap.TryGetValue(prop, out navProp))
                    continue;

                var related = entry.RelationshipManager.GetRelatedEnd(navProp.RelationshipType.FullName, navProp.ToEndMember.Name);
                var enumerator = related.GetEnumerator();
                if (enumerator.MoveNext() && enumerator.Current != null)
                    continue;

                entry.Delete();
                break;
            }
        }
    }

    private static ReadOnlyDictionary<string, NavigationProperty> CreateNavigationPropertyMap( EntityType type )
    {
        var result = type.NavigationProperties
            .Where(v => v.FromEndMember.RelationshipMultiplicity == RelationshipMultiplicity.Many)
            .Where(v => v.ToEndMember.RelationshipMultiplicity == RelationshipMultiplicity.One || (v.ToEndMember.RelationshipMultiplicity == RelationshipMultiplicity.ZeroOrOne && v.FromEndMember.GetEntityType() == v.ToEndMember.GetEntityType()))
            .Select(v => new { NavigationProperty = v, DependentProperties = v.GetDependentProperties().Take(2).ToArray() })
            .Where(v => v.DependentProperties.Length == 1)
            .ToDictionary(v => v.DependentProperties[0].Name, v => v.NavigationProperty);

        return new ReadOnlyDictionary<string, NavigationProperty>(result);
    }
}

I have done something like this abstract class that can be used in place of TextView.OnEditorActionListener type.

abstract class OnTextEndEditingListener : TextView.OnEditorActionListener {

    override fun onEditorAction(textView: TextView?, actionId: Int, event: KeyEvent?): Boolean {

        if(actionId == EditorInfo.IME_ACTION_SEARCH ||
                actionId == EditorInfo.IME_ACTION_DONE ||
                actionId == EditorInfo.IME_ACTION_NEXT ||
                event != null &&
                event.action == KeyEvent.ACTION_DOWN &&
                event.keyCode == KeyEvent.KEYCODE_ENTER) {

            if(event == null || !event.isShiftPressed) {
                // the user is done typing.
                return onTextEndEditing(textView, actionId, event)
            }
        }
        return false // pass on to other listeners
    }

    abstract fun onTextEndEditing(textView: TextView?, actionId: Int, event: KeyEvent?) : Boolean
}

To strip any whitespace, you can use a regular expression

$str=preg_replace('/\s+/', '', $str);

See also this answer for something which can handle whitespace in UTF-8 strings.

@niutech I was having the similar issue which is caused by Rocket Loader Module by Cloudflare. Just disable it for the website and it will sort out all your related issues.

I would use expr match instead of =~:

expr match "$date" "[0-9]\{8\}" >/dev/null && echo yes

This is better than the currently accepted answer of using =~ because =~ will also match empty strings, which IMHO it shouldn't. Suppose badvar is not defined, then [[ "1234" =~ "$badvar" ]]; echo $? gives (incorrectly) 0, while expr match "1234" "$badvar" >/dev/null ; echo $? gives correct result 1.

We have to use >/dev/null to hide expr match's output value, which is the number of characters matched or 0 if no match found. Note its output value is different from its exit status. The exit status is 0 if there's a match found, or 1 otherwise.

Generally, the syntax for expr is:

expr match "$string" "$lead"

Or:

expr "$string" : "$lead"

where $lead is a regular expression. Its exit status will be true (0) if lead matches the leading slice of string (Is there a name for this?). For example expr match "abcdefghi" "abc"exits true, but expr match "abcdefghi" "bcd" exits false. (Credit to @Carlo Wood for pointing out this.

Eclipse TCF team has just release terminal (SSH, Telnet, local)

originally named TCF Terminal, then renamed to TM Terminal

http://marketplace.eclipse.org/content/tcf-terminals

Finally Windows and Linux all supported

Support for Git Bash on Windows is resolved Bug 435014.

This plugin is included into Enide Studio 2014 and Enide 2015.

To access the terminal go to Window -> Show View -> Terminal or Ctrl+Alt+T

You could use a labeled BREAK statement:

search:
    for (i = 0; i < arrayOfInts.length; i++) {
        for (j = 0; j < arrayOfInts[i].length; j++) {
            if (arrayOfInts[i][j] == searchfor) {
                foundIt = true;
                break search;
            }
        }
    }

However, in properly designed code, you shouldn't need GOTO functionality.

String[] elements = { "a", "a", "a", "a" };

for( int i = 0; i < elements.length - 1; i++)
{
    String element = elements[i];
    String nextElement = elements[i+1];
}

Note that in this case, elements.length is 4, so you want to iterate from [0,2] to get elements 0,1, 1,2 and 2,3.

try this=> numpy.array(yourvariable) followed by the command to compare, whatever you wish to.

Don't over-complicate things when you can do:

var isProperty =  (objectname.keyname || "") ? true : false;

It Is simple and clear for most cases...

In Python you can use (.)\1{9,}

• (.) makes group from one char (any char)
• \1{9,} matches nine or more characters from 1st group

example:

txt = """1. aaaaaaaaaaaaaaa
2. bb
3. cccccccccccccccccccc
4. dd
5. eeeeeeeeeeee"""
rx = re.compile(r'(.)\1{9,}')
lines = txt.split('\n')
for line in lines:
    rxx = rx.search(line)
    if rxx:
        print line

Output:

1. aaaaaaaaaaaaaaa
3. cccccccccccccccccccc
5. eeeeeeeeeeee

I had the same problem for a bit. I noticed that I had:

Data Source= (localdb)\v11.0"

Simply by adding one back-slash it solved the problem for me:

Data Source= (localdb)\\v11.0"

Recently I had this same problem on windows 10 - after installing Hyper-V & other windows features like:

Windows Projected File System, Windows Sandbox, Windows Subsystem for Linux, Work Folders Client,

And it stopped working for me;(

1. Step uninstall Hyper-V -check if ti stared to work for you - no in my case
2. Step uninstall other windows features mentioned above! - I worked for me;)

As it has already been mentioned in che's answer about adding the remote part, which I believe you are still missing.

Regarding your edit for adding remote on your local USB drive. First of all you must have a 'bare repository' if you want your repository to be a shared repository i.e. to be able to push/pull/fetch/merge etc..

To create a bare/shared repository, go to your desired location. In your case:

$ cd /Volumes/500gb/   
$ git init --bare myproject.git

See here for more info on creating bare repository

Once you have a bare repository set up in your desired location you can now add it to your working copy as a remote.

$ git remote add origin /Volumes/500gb/myproject.git

And now you can push your changes to your repository

$ git push origin master

My jQuery ajax settings:

        $.ajax({
        headers: {'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')},
        url: url,
        dataType: "json",
        type: "post",
        data: params,
        success: function (resp){
            ....
        },
        error: responseFunc
    });

And now i am able to get the request via $request->all() in Laravel

dataType: "json"

is the important part in the ajax request to handle the response as an json object and not string.

Wildcard works for me also, but I'd like to give a side note for those using directory variables. Always use slash for folder tree (not backslash), otherwise it will fail:

BASEDIR = ../..
SRCDIR = $(BASEDIR)/src
INSTALLDIR = $(BASEDIR)/lib

MODULES = $(wildcard $(SRCDIR)/*.cpp)
OBJS = $(wildcard *.o)

MySQL can index the first x characters of a column,but a TEXT type is of variable length so mysql cant assure the uniqueness of the column.If you still want text column,use VARCHAR.

@if ($errors->has('category'))
    <span class="error">{{ $errors->first('category') }}</span>
@endif

It can be understood like this:

var a= []; //creates a new empty array
var a= {}; //creates a new empty object

You can also understand that

var a = {}; is equivalent to var a= new Object();

Note:

You can use Arrays when you are bothered about the order of elements(of same type) in your collection else you can use objects. In objects the order is not guaranteed.

$date = strtotime("+1 day");
echo date('m-d-y',$date);

Are you after something like this:

 <html>
 <head>
    <title>Z Test</title>
 </head>
 <body>

<div id="img_home"></div>

<button onclick="addimage()" type="button">Add an image</button>

<script>
function addimage() {
    var img = new Image();
    img.src = "https://www.google.com/images/srpr/logo4w.png"
    img_home.appendChild(img);
}
</script>
</body>

That is exactly how you do it in C#, but the feature was first added in .NET 4.0

To delete all directories with the name foo, run:

find -type d -name foo -a -prune -exec rm -rf {} \;

The other answers are missing an important thing: the -prune option. Without -prune, GNU find will delete the directory with the matching name and then try to recurse into it to find more directories that match. The -prune option tells it to not recurse into a directory that matched the conditions.

In the example below, if you comment out the override for equals or hashcode in the Person class, this code will fail to look up Tom's order. Using the default implementation of hashcode can cause failures in hashtable lookups.

What I have below is a simplified code that pulls up people's order by Person. Person is being used as a key in the hashtable.

public class Person {
    String name;
    int age;
    String socialSecurityNumber;

    public Person(String name, int age, String socialSecurityNumber) {
        this.name = name;
        this.age = age;
        this.socialSecurityNumber = socialSecurityNumber;
    }

    @Override
    public boolean equals(Object p) {
        //Person is same if social security number is same

        if ((p instanceof Person) && this.socialSecurityNumber.equals(((Person) p).socialSecurityNumber)) {
            return true;
        } else {
            return false;
        }

    }

    @Override
    public int hashCode() {        //I am using a hashing function in String.java instead of writing my own.
        return socialSecurityNumber.hashCode();
    }
}


public class Order {
    String[]  items;

    public void insertOrder(String[]  items)
    {
        this.items=items;
    }

}



import java.util.Hashtable;

public class Main {

    public static void main(String[] args) {

        hashtable.put(p3,order3);

       //The line below will fail if Person class does not override hashCode()
       Order tomOrder= hashtable.get(new Person("Tom", 32, "548-56-4412"));
        for(String item:tomOrder.items)
        {
            System.out.println(item);
        }
    }
}

List<String> list = Arrays.asList(array);

The list returned will be backed by the array, it acts like a bridge, so it will be fixed-size.

After I changed the theme it behaved strangely. The font size was small, cannot see the toolbar and I really didn't like the new look.

For those who want to restore the original theme, you can do it as follows:

jt -r

You need to restart Jupyter the first time you do it and later refresh is enough to enable the new theme.

or directly from inside the notebook

!jt -r

I think if you think it from the point of CALayer, everything is more clear.

Frame is not really a distinct property of the view or layer at all, it is a virtual property, computed from the bounds, position(UIView's center), and transform.

So basically how the layer/view layouts is really decided by these three property(and anchorPoint), and either of these three property won't change any other property, like changing transform doesn't change bounds.

My guess is that byteArrayIn doesn't contain valid image data.

Please give more information though:

• Which line of code is throwing an exception?
• What's the message?
• Where did you get byteArrayIn from, and are you sure it should contain a valid image?

My initial thought is that you are missing an entry in the hosts file. Something like "127.0.0.1 localhost", however, you mention that you are getting a 404 error. That means that the webserver is connecting to your client/browser and responding to the request for a particular webpage.

I'm not familiar enough with Windows 7, however, I'm pretty sure that it does not include a webserver by default. Also, unless you actually code, build and run a webserver application using netbeans you're not going to get the desired response.

When it comes down to it.... your issue is going to be one of the following:

1) you're serving static documents and the webserver is not configured to serve the files from whatever the proper DOCROOT should be. This includes PUBLIC folders in the user's directories. (the basic apache install include a basic homepage)

2) you have a dynamic webserver application where the controller is looking at the application path in order to decide what page to display or what function to execute. (see MVC - Controller). Basically incomplete implementation.

3) yet another configuration error: your website might actually define a virtual domain. (something other than localhost) so when you look for localhost in the URL the server might not be configured to provide a default page.

If you want to bind to the redis port from your nodejs container you will have to expose that port in the redis container:

version: '2'
services:
  nodejs:
    build:
      context: .
      dockerfile: DockerFile
    ports:
      - "4000:4000"
    links:
      - redis

  redis:
    build:
      context: .
      dockerfile: Dockerfile-redis
    expose:
      - "6379"

The expose tag will let you expose ports without publishing them to the host machine, but they will be exposed to the containers networks.

https://docs.docker.com/compose/compose-file/#expose

The ports tag will be mapping the host port with the container port HOST:CONTAINER

https://docs.docker.com/compose/compose-file/#ports

For general command-line automation, Expect is the classic tool. Or try pexpect if you're more comfortable with Python.

Here's a similar question that suggests using Expect: Use expect in bash script to provide password to SSH command

If you already know size of the char*, use this instead

char* data = ...;
int size = ...;
std::string myString(data, size);

This doesn't use strlen.

EDIT: If string variable already exists, use assign():

std::string myString;
char* data = ...;
int size = ...;
myString.assign(data, size);

This webpage have an explanation and a solution.

The solution is:

To fix this problem the behavior of the kernel has to be changed, so it will no longer overcommit the memory for application requests. Finally I have included those mentioned values into the /etc/sysctl.conf file, so they get automatically applied on start-up:

vm.overcommit_memory = 2

vm.overcommit_ratio = 80

The SUBTOTAL function can be used if you want to get the count respecting any filters you use on the page.

=SUBTOTAL(103, A1:A200)

will help you get count of non-empty rows, respecting filters.

103 - is similar to COUNTA, but ignores empty rows and also respects filters.

Reference : SUBTOTAL function

Packets and Frames are the names given to Protocol data units (PDUs) at different network layers

• Segments/Datagrams are units of data in the Transport Layer.

  In the case of the internet, the term Segment typically refers to TCP, while Datagram typically refers to UDP. However Datagram can also be used in a more general sense and refer to other layers (link):

  Datagram

  A self-contained, independent entity of data carrying sufficient information to be routed from the source to the destination computer without reliance on earlier exchanges between this source and destination computer andthe transporting network.

• Packets are units of data in the Network Layer (IP in case of the Internet)

• Frames are units of data in the Link Layer (e.g. Wifi, Bluetooth, Ethernet, etc).

The reason that your HTML is replaced is because of an evil JavaScript function: document.write().

It is most definitely "bad form." It only works with webpages if you use it on the page load; and if you use it during runtime, it will replace your entire document with the input. And if you're applying it as strict XHTML structure it's not even valid code.

the problem:

document.write writes to the document stream. Calling document.write on a closed (or loaded) document automatically calls document.open which will clear the document.

-- quote from the MDN

document.write() has two henchmen, document.open(), and document.close(). When the HTML document is loading, the document is "open". When the document has finished loading, the document has "closed". Using document.write() at this point will erase your entire (closed) HTML document and replace it with a new (open) document. This means your webpage has erased itself and started writing a new page - from scratch.

I believe document.write() causes the browser to have a performance decrease as well (correct me if I am wrong).

an example:

This example writes output to the HTML document after the page has loaded. Watch document.write()'s evil powers clear the entire document when you press the "exterminate" button:

I am an ordinary HTML page.  I am innocent, and purely for informational purposes. Please do not <input type="button" onclick="document.write('This HTML page has been succesfully exterminated.')" value="exterminate"/>_x000D_
me!

the alternatives:

• .innerHTML This is a wonderful alternative, but this attribute has to be attached to the element where you want to put the text.

Example: document.getElementById('output1').innerHTML = 'Some text!';

• .createTextNode() is the alternative recommended by the W3C.

Example: var para = document.createElement('p'); para.appendChild(document.createTextNode('Hello, '));

NOTE: This is known to have some performance decreases (slower than .innerHTML). I recommend using .innerHTML instead.

the example with the .innerHTML alternative:

I am an ordinary HTML page. _x000D_
I am innocent, and purely for informational purposes. _x000D_
Please do not _x000D_
<input type="button" onclick="document.getElementById('output1').innerHTML = 'There was an error exterminating this page. Please replace <code>.innerHTML</code> with <code>document.write()</code> to complete extermination.';" value="exterminate"/>_x000D_
 me!_x000D_
<p id="output1"></p>

This is a bit outside the scope of your question, but to avoid any potential confusion for readers who are new to VBA: End and End Sub are not the same. They don't perform the same task.

End puts a stop to ALL code execution and you should almost always use Exit Sub (or Exit Function, respectively).

End halts ALL exectution. While this sounds tempting to do it also clears all global and static variables. (source)

See also the MSDN dox for the End Statement

When executed, the End statement resets allmodule-level variables and all static local variables in allmodules. To preserve the value of these variables, use the Stop statement instead. You can then resume execution while preserving the value of those variables.

Note The End statement stops code execution abruptly, without invoking the Unload, QueryUnload, or Terminate event, or any other Visual Basic code. Code you have placed in the Unload, QueryUnload, and Terminate events offorms andclass modules is not executed. Objects created from class modules are destroyed, files opened using the Open statement are closed, and memory used by your program is freed. Object references held by other programs are invalidated.

Nor is End Sub and Exit Sub the same. End Sub can't be called in the same way Exit Sub can be, because the compiler doesn't allow it.

This again means you have to Exit Sub, which is a perfectly legal operation:

Exit Sub
Immediately exits the Sub procedure in which it appears. Execution continues with the statement following the statement that called the Sub procedure. Exit Sub can be used only inside a Sub procedure.

Additionally, and once you get the feel for how procedures work, obviously, End Sub does not clear any global variables. But it does clear local (Dim'd) variables:

End Sub
Terminates the definition of this procedure.

Not sure if there was file corruption or what, but after confirming proper pom configuration I was able to resolve this issue by deleting the jar from my local m2 repository, forcing Maven to download it again when I ran the tests.

What worked for me: I finally noticed the Build Executor Status window on the left on the main Jenkins dashboard. I run a dev/test instance on my local system with 2 executors. Both were currently occupied with builds that were not running. Upon cancelling these to jobs, my third (pending) job was able to run.

EDIT:

Ok I found why the int.ToString() in LINQtoEF fails, please read this post: Problem with converting int to string in Linq to entities

This works on my side :

        List<string> materialTypes = (from u in result.Users
                                      select u.LastName)
                       .Union(from u in result.Users
                               select SqlFunctions.StringConvert((double) u.UserId)).ToList();

On yours it should be like this:

    IList<String> materialTypes = ((from tom in context.MaterialTypes
                                       where tom.IsActive == true
                                       select tom.Name)
                                       .Union(from tom in context.MaterialTypes
                                       where tom.IsActive == true
                                       select SqlFunctions.StringConvert((double)tom.ID))).ToList();

Thanks, i've learnt something today :)

The easiest is to just add 0.5f to it and then cast this to an int.

For me the case was completely different. I had created a studio64.exe.vmoptions file in C:\Users\YourUserName\.AndroidStudio3.4\config. In that folder, I had a typo of extra spaces. Due to that I was getting the same error.

# custom Android Studio VM options, see https://developer.android.com/studio/intro/studio-config.html

This is a bit confusing, but follow these steps to save the session.

1. Category -> Session -> enter public IP in Host and 22 in port.
2. Connection -> SSH -> Auth -> select the .ppk file
3. Category -> Session -> enter a name in Saved Session -> Click Save

To open the session, double click on particular saved session.

Try the below query

CREATE TABLE card_types (
  card_type_id int(11) NOT NULL auto_increment,
  name varchar(50) NOT NULL default '',
  PRIMARY KEY  (card_type_id),
) ENGINE = MyISAM ;

As Karim said, cross domain ajax doesn't work unless the server allows for it. In this case Google does not, BUT, there is a simple trick to get around this in many cases. Just have your local server pass the content retrieved through HTTP or HTTPS.

For example, if you were using PHP, you could:

Create the file web_root/ajax_responders/google.php with:

<?php
  echo file_get_contents('http://www.google.de');
?>

And then alter your code to connect to that instead of to Google's domain directly in the javascript:

var response = $.ajax({ type: "GET",   
                        url: "/ajax_responders/google.php",   
                        async: false
                      }).responseText;
alert(response);

If you are using SQL Server 2012+ vote for Martin Smith's answer and use the OFFSET and FETCH NEXT extensions to ORDER BY,

If you are unfortunate enough to be stuck with an earlier version, you could do something like this,

WITH Rows AS
(
    SELECT
              ROW_NUMBER() OVER (ORDER BY [dbo].[SomeColumn]) [Row]
            , *
        FROM
              [dbo].[SomeTable]
)
SELECT TOP 10
          *
     FROM
         Rows
    WHERE Row > 10

I believe is functionaly equivalent to

SELECT * FROM SomeTable LIMIT 10 OFFSET 10 ORDER BY SomeColumn

and the best performing way I know of doing it in TSQL, before MS SQL 2012.

If there are very many rows you may get better performance using a temp table instead of a CTE.

I tried almost all the suggestions in most of the answers (the most popular), nothing was helping. Finally, I found the reason in my case. I used a bad USB cable. I change to another original USB cable - and it immediately worked!!!.

I hope it helps someone else.

I remember I had the same problem a while back using WCF due the quantity of the data I was passing. I remember I changed timeouts everywhere but the problem persisted. What I finally did was open the connection as stream request, I needed to change the client and the server side, but it work that way. Since it was a stream connection, the server kept reading until the stream ended.

You are right that CSS positioning is the way to go. Here's a quick run down:

position: relative will layout an element relative to itself. In other words, the elements is laid out in normal flow, then it is removed from normal flow and offset by whatever values you have specified (top, right, bottom, left). It's important to note that because it's removed from flow, other elements around it will not shift with it (use negative margins instead if you want this behaviour).

However, you're most likely interested in position: absolute which will position an element relative to a container. By default, the container is the browser window, but if a parent element either has position: relative or position: absolute set on it, then it will act as the parent for positioning coordinates for its children.

To demonstrate:

#container {_x000D_
  position: relative;_x000D_
  border: 1px solid red;_x000D_
  height: 100px;_x000D_
}_x000D_
_x000D_
#box {_x000D_
  position: absolute;_x000D_
  top: 50px;_x000D_
  left: 20px;_x000D_
}

<div id="container">_x000D_
  <div id="box">absolute</div>_x000D_
</div>

In that example, the top left corner of #box would be 100px down and 50px left of the top left corner of #container. If #container did not have position: relative set, the coordinates of #box would be relative to the top left corner of the browser view port.

On Windows system, you have to make empty the following file ~/.docker/config.json and then run again the below script

aws ecr get-login --no-include-email --region ap-southeast-1 --profile [profile_name]

I had same issue at the last half hour...

Was not able to delete a zombie build running in my multi-branch pipeline. Even Server restarts by UI or even from commandline via sudo service jenkins restart did block the execution... The build was not stoppable... It always reapeared.

Used Version: Jenkins ver 2.150.2

I was very annoyed, but... when looking into the log of the build I found something intersting at the end of the log:

The red marked parts are the "frustrating parts"... As you can see I always wanted to Abort the build from UI but it did not work...

But there is a hyperlink with text Click here to forcibly terminate running steps...(first green one) Now I pressed the link...) After the link execution a message about Still paused appeared with another Link Click here to forcibily kill entire build (second green one) After pressing this link also the build finally was hard killed...

So this seems to work without any special plugins (except the multibranch-pipeline build plugin itself).

Although everyone answer "No" and I know that "No" is the right answer but if you really need to get local variables of a function there is a restricted way.

Consider this function:

var f = function() {
    var x = 0;
    console.log(x);
};

You can convert your function to a string:

var s = f + '';

You will get source of function as a string

'function () {\nvar x = 0;\nconsole.log(x);\n}'

Now you can use a parser like esprima to parse function code and find local variable declarations.

var s = 'function () {\nvar x = 0;\nconsole.log(x);\n}';
s = s.slice(12); // to remove "function () "
var esprima = require('esprima');
var result = esprima.parse(s);

and find objects with:

obj.type == "VariableDeclaration"

in the result (I have removed console.log(x) below):

{
    "type": "Program",
    "body": [
        {
            "type": "VariableDeclaration",
            "declarations": [
                {
                    "type": "VariableDeclarator",
                    "id": {
                        "type": "Identifier",
                        "name": "x"
                    },
                    "init": {
                        "type": "Literal",
                        "value": 0,
                        "raw": "0"
                    }
                }
            ],
            "kind": "var"
        }
    ]
}

I have tested this in Chrome, Firefox and Node.

But the problem with this method is that you just have the variables defined in the function itself. For example for this one:

var g = function() {
    var y = 0;
    var f = function() {
        var x = 0;
        console.log(x);
    };
}

you just have access to the x and not y. But still you can use chains of caller (arguments.callee.caller.caller.caller) in a loop to find local variables of caller functions. If you have all local variable names so you have scope variables. With the variable names you have access to values with a simple eval.

I'm sorry, I managed to find the answer myself using google and a bit of luck : )

For those interested;

I installed the pdftk (pdf toolkit) on our debian server, and using the following command I achieved desired output:

pdftk file1.pdf file2.pdf cat output output.pdf

OR

gs -q -sPAPERSIZE=letter -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -sOutputFile=output.pdf file1.pdf file2.pdf file3.pdf ...

This in turn can be piped directly into pdf2ps.

Actually I think that more general approach to loop through dictionary is to use iteritems():

# get tuples of term, courses
for term, term_courses in courses.iteritems():
    # get tuples of course number, info
    for course, info in term_courses.iteritems():
        # loop through info
        for k, v in info.iteritems():
            print k, v

output:

assistant Peter C.
prereq cs101
...
name Programming a Robotic Car
teacher Sebastian

Or, as Matthias mentioned in comments, if you don't need keys, you can just use itervalues():

for term_courses in courses.itervalues():
    for info in term_courses.itervalues():
        for k, v in info.iteritems():
            print k, v

First answer is still valid, but the API has changed in the past. Since my edit there wasn't accepted I post it as separate answer.

The method authentication() is only used to provide the authentication method (e.g. Basic) but not any credentials.

You also shouldn't use it since it's printing the credentials plain on failure!

This his how it should look like in your build.gradle

    maven {
        credentials {
            username "$mavenUser"
            password "$mavenPassword"
        }
        url 'https://maven.yourcorp.net/'
   }

In gradle.properties in your userhome dir put:

mavenUser=admin
mavenPassword=admin123

Also ensure that the GRADLE_USER_HOME is set to ~/.gradle otherwise the properties file there won't be resolved.

on jquery

$('.aaf').on("click",function(){
  var usersid =  $(this).attr("id");

//other method is to use the data attribute

Use C# Dictionary datastructure it good for you...

Dictionary<string, int> dict = new Dictionary<string, int>();
dict.Add("one", 1);
dict.Add("two", 2);

You can retrieve data from Ditionary in a simple way..

foreach (KeyValuePair<string, int> pair in dict)
{
    MessageBox.Show(pair.Key.ToString ()+ "  -  "  + pair.Value.ToString () );
}

volatile and transient keywords

1) transient keyword is used along with instance variables to exclude them from serialization process. If a field is transient its value will not be persisted.

On the other hand, volatile keyword is used to mark a Java variable as "being stored in main memory".

Every read of a volatile variable will be read from the computer's main memory, and not from the CPU cache, and that every write to a volatile variable will be written to main memory, and not just to the CPU cache.

2) transient keyword cannot be used along with static keyword but volatile can be used along with static.

3) transient variables are initialized with default value during de-serialization and there assignment or restoration of value has to be handled by application code.

For more information, see my blog:
http://javaexplorer03.blogspot.in/2015/07/difference-between-volatile-and.html

As mentioned before, you might need GD library installed.

On a shell, check your php version first:
php -v

Then install accordingly. In my system (Linux-Ubuntu) it's php version 7.0:
sudo apt-get install php7.0-gd

Restart your webserver:
systemctl restart apache2

You should now have GD library installed and enabled.

app.use(bodyParser.urlencoded({extended: true}));

I have the same problem but this work for me. You can try this extended part.

$('#content').html('whatever');

I also had the same issue. I changed it to the following and it worked.

@RequestMapping(value = "/test", method = RequestMethod.GET)

HTML code:

  <form action="<%=request.getContextPath() %>/test" method="GET">
    <input type="submit" value="submit"> 
    </form>

By default if you do not specify http method in a form it uses GET. To use POST method you need specifically state it.

Hope this helps.

when you select run configuration, there is a JRE tap up next the main tap, select "Workspace default JRE(JDK1.7)".

Be sure to use the jdk in Prefs->Java->Installed JREs ->Execution Environment

I believe this will solve the issue

var z = '[{"name":"1","age":"2"},{"name":"1","age":"3"}]';
z = JSON.stringify(JSON.parse(z));
$.ajax({
    url: "/setTest",
    data: z,
    type: "POST",
    dataType:"json",
    contentType:'application/json'               
});

You probably do not need to be making lists and appending them to make your array. You can likely just do it all at once, which is faster since you can use numpy to do your loops instead of doing them yourself in pure python.

To answer your question, as others have said, you cannot access a nested list with two indices like you did. You can if you convert mean_data to an array before not after you try to slice it:

R = np.array(mean_data)[:,0]

instead of

R = np.array(mean_data[:,0])

But, assuming mean_data has a shape nx3, instead of

R = np.array(mean_data)[:,0]
P = np.array(mean_data)[:,1]
Z = np.array(mean_data)[:,2]

You can simply do

A = np.array(mean_data).mean(axis=0)

which averages over the 0th axis and returns a length-n array

But to my original point, I will make up some data to try to illustrate how you can do this without building any lists one item at a time:

Found this in another thread that helped me: Use xp_cmdshell and sqlcmd Is it possible to execute a text file from SQL query? - by Gulzar Nazim

EXEC xp_cmdshell  'sqlcmd -S ' + @DBServerName + ' -d  ' + @DBName + ' -i ' + @FilePathName

Just create a new branch with git checkout -b ABC_1; your uncommitted changes will be kept, and you then commit them to that branch.

A step by step guide I found here.

To create a read-only database user account for MySQL

At a UNIX prompt, run the MySQL command-line program, and log in as an administrator by typing the following command:

mysql -u root -p

Type the password for the root account. At the mysql prompt, do one of the following steps:

To give the user access to the database from any host, type the following command:

grant select on database_name.* to 'read-only_user_name'@'%' identified by 'password';

If the collector will be installed on the same host as the database, type the following command:

grant select on database_name.* to 'read-only_user_name' identified by 'password';

This command gives the user read-only access to the database from the local host only. If you know the host name or IP address of the host that the collector is will be installed on, type the following command:

grant select on database_name.* to 'read-only_user_name'@'host_name or IP_address' identified by 'password';

The host name must be resolvable by DNS or by the local hosts file. At the mysql prompt, type the following command:

flush privileges;

Type quit.

The following is a list of example commands and confirmation messages:

mysql> grant select on dbname.* to 'readonlyuser'@'%' identified 
by 'pogo$23';
Query OK, 0 rows affected (0.11 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
mysql> quit

Here is a function I did to return a list with a string(s) inbetween string1 and string2 searched.

def GetListOfSubstrings(stringSubject,string1,string2):
    MyList = []
    intstart=0
    strlength=len(stringSubject)
    continueloop = 1

    while(intstart < strlength and continueloop == 1):
        intindex1=stringSubject.find(string1,intstart)
        if(intindex1 != -1): #The substring was found, lets proceed
            intindex1 = intindex1+len(string1)
            intindex2 = stringSubject.find(string2,intindex1)
            if(intindex2 != -1):
                subsequence=stringSubject[intindex1:intindex2]
                MyList.append(subsequence)
                intstart=intindex2+len(string2)
            else:
                continueloop=0
        else:
            continueloop=0
    return MyList


#Usage Example
mystring="s123y123o123pp123y6"
List = GetListOfSubstrings(mystring,"1","y68")
for x in range(0, len(List)):
               print(List[x])
output:


mystring="s123y123o123pp123y6"
List = GetListOfSubstrings(mystring,"1","3")
for x in range(0, len(List)):
              print(List[x])
output:
    2
    2
    2
    2

mystring="s123y123o123pp123y6"
List = GetListOfSubstrings(mystring,"1","y")
for x in range(0, len(List)):
               print(List[x])
output:
23
23o123pp123

Try this first, you may be passing a Null Model:

@if (Model != null && !String.IsNullOrEmpty(Model.ImageName))
{
    <label for="Image">Change picture</label>
}
else
{ 
    <label for="Image">Add picture</label>
}

Otherise, you can make it even neater with some ternary fun! - but that will still error if your model is Null.

<label for="Image">@(String.IsNullOrEmpty(Model.ImageName) ? "Add" : "Change") picture</label>

I know this is a very old thread but I wish to post this to help those who bump into this like I did.

if you don't care about using a 3rd party script, you can use moment,js Then you can use .format() to format it to anything you want it to.

Carry Flag

The rules for turning on the carry flag in binary/integer math are two:

1. The carry flag is set if the addition of two numbers causes a carry out of the most significant (leftmost) bits added. 1111 + 0001 = 0000 (carry flag is turned on)

2. The carry (borrow) flag is also set if the subtraction of two numbers requires a borrow into the most significant (leftmost) bits subtracted. 0000 - 0001 = 1111 (carry flag is turned on) Otherwise, the carry flag is turned off (zero).

   • 0111 + 0001 = 1000 (carry flag is turned off [zero])
   • 1000 - 0001 = 0111 (carry flag is turned off [zero])

In unsigned arithmetic, watch the carry flag to detect errors.

In signed arithmetic, the carry flag tells you nothing interesting.

Overflow Flag

The rules for turning on the overflow flag in binary/integer math are two:

1. If the sum of two numbers with the sign bits off yields a result number with the sign bit on, the "overflow" flag is turned on. 0100 + 0100 = 1000 (overflow flag is turned on)

2. If the sum of two numbers with the sign bits on yields a result number with the sign bit off, the "overflow" flag is turned on. 1000 + 1000 = 0000 (overflow flag is turned on)

Otherwise the "overflow" flag is turned off

• 0100 + 0001 = 0101 (overflow flag is turned off)
• 0110 + 1001 = 1111 (overflow flag turned off)
• 1000 + 0001 = 1001 (overflow flag turned off)
• 1100 + 1100 = 1000 (overflow flag is turned off)

Note that you only need to look at the sign bits (leftmost) of the three numbers to decide if the overflow flag is turned on or off.

If you are doing two's complement (signed) arithmetic, overflow flag on means the answer is wrong - you added two positive numbers and got a negative, or you added two negative numbers and got a positive.

If you are doing unsigned arithmetic, the overflow flag means nothing and should be ignored.

For more clarification please refer: http://teaching.idallen.com/dat2343/10f/notes/040_overflow.txt

UPDATE play_school_data SET title= REPLACE(title, "'", "'") WHERE title = "Elmer's Parade";

Result:

title = Elmer's Parade

Try array_merge.

$array1 = array('Item 1');

$array2 = array('Item 2');

$array3 = array_merge($array1, $array2);

I think its because you are not assigning a key to either, so they both have key of 0, and the + does not re-index, so its trying to over write it.

for python language, you can do like this

import pymysql

connection = pymysql.connect(host='localhost',
                             user='root',
                             db='mysql',
                             cursorclass=pymysql.cursors.DictCursor)

with connection.cursor() as cursor:
    cursor.execute('SHOW PROCESSLIST')
    for item in cursor.fetchall():
        if item.get('Time') > 200:
            _id = item.get('Id')
            print('kill %s' % item)
            cursor.execute('kill %s', _id)
    connection.close()

You probably want a dict instead of separate variables. For example

d = {}
for i in range(3):
    d["group" + str(i)] = self.getGroup(selected, header+i)

If you insist on actually modifying local variables, you could use the locals function:

for i in range(3):
    locals()["group"+str(i)] = self.getGroup(selected, header+i)

On the other hand, if what you actually want is to modify instance variables of the class you're in, then you can use the setattr function

for i in group(3):
    setattr(self, "group"+str(i), self.getGroup(selected, header+i)

And of course, I'm assuming with all of these examples that you don't just want a list:

groups = [self.getGroup(i,header+i) for i in range(3)]
