Programs & Examples On #Script fu

You have a few different options:

• you can use a SPA router like SammyJS, or Angularjs and ui-router, so your pages are stateful.
• use sessionStorage to store your state.
• store the values on the URL hash.

Working example in php.
First Alert then Redirect works....
Enjoy...

echo "<script>";
echo " alert('Import has successfully Done.');      
        window.location.href='".site_url('home')."';
      </script>";

Neither is good.

Behaviour should be configured independent of the actual markup. For instance, in jQuery you might do something like

$('#the-element').click(function () { /* perform action here */ });

in a separate <script> block.

The advantage of this is that it

1. Separates markup and behaviour in the same way that CSS separates markup and style
2. Centralises configuration (this is somewhat a corollary of 1).
3. Is trivially extensible to include more than one argument using jQuery’s powerful selector syntax

Furthermore, it degrades gracefully (but so would using the onclick event) since you can provide the link tags with a href in case the user doesn’t have JavaScript enabled.

Of course, these arguments still count if you’re not using jQuery or another JavaScript library (but why do that?).

ES2015 onwards:

From ES6/ES2015, we have default parameters in the language specification. So we can just do something simple like,

function A(a, b = 4, c = 5) {
}

or combined with ES2015 destructuring,

function B({c} = {c: 2}, [d, e] = [3, 4]) {
}

For detailed explanation,

https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Functions/default_parameters

Default function parameters allow formal parameters to be initialized with default values if no value or undefined is passed.

Pre ES2015:

If you're going to handle values which are NOT Numbers, Strings, Boolean, NaN, or null you can simply use

(So, for Objects, Arrays and Functions that you plan never to send null, you can use)

param || DEFAULT_VALUE

for example,

function X(a) {
  a = a || function() {};
}

Though this looks simple and kinda works, this is restrictive and can be an anti-pattern because || operates on all falsy values ("", null, NaN, false, 0) too - which makes this method impossible to assign a param the falsy value passed as the argument.

So, in order to handle only undefined values explicitly, the preferred approach would be,

function C(a, b) {
  a = typeof a === 'undefined' ? DEFAULT_VALUE_A : a;
  b = typeof b === 'undefined' ? DEFAULT_VALUE_B : b;
}

String.prototype.padZero= function(len, c){
    var s= this, c= c || '0';
    while(s.length< len) s= c+ s;
    return s;
}

dispite the name, you can left-pad with any character, including a space. I never had a use for right side padding, but that would be easy enough.

you could access the data using $('#prod')[0].dataset

In the POSIX standard, which /bin/sh is supposed to respect, the command is . (a single dot), not source. The source command is a csh-ism that has been pulled into bash.

Try

. $env_name/bin/activate

Or if you must have non-POSIX bash-isms in your code, use #!/bin/bash.

I'm sorry, I still yet cant comment, so to answer Tom's answer... In javascript (undefined != null) == false In fact that function wont work with "null", you should use "undefined"

The following is equivalent to your second code block:

var f = function () {
        //Some logic here...
    };

var fr = f;

fr(pars);

If you want to actually pass a reference to a function to some other function, you can do something like this:

function fiz(x, y, z) {
    return x + y + z;
}

// elsewhere...

function foo(fn, p, q, r) {
    return function () {
        return fn(p, q, r);
    }
}

// finally...

f = foo(fiz, 1, 2, 3);
f(); // returns 6

You're almost certainly better off using a framework for this sort of thing, though.

I had the same exception in JPA 2 using eclipse link. I had an @embedded class with one to one relationship with an entity. By mistake ,in the embedded class, i had also the annotation @Table("TRADER"). When the DB was created by the JPA from the entities it also created a table TRADER (which was a wrong as the Trader entity was embedded to the main entity) and the existence of that table was causing the above exception every time i was trying to persist my entity. After deleting the TRADER table the exception disappered.

Another option is:

<Grid container justify = "center">
  <Your centered component/>
</Grid>

Here is some information about one more source of the JSESSIONID cookie:

I was just debugging some Java code that runs on a tomcat server. I was not calling request.getSession() explicitly anywhere in my code but I noticed that a JSESSIONID cookie was still being set.

I finally took a look at the generated Java code corresponding to a JSP in the work directory under Tomcat.

It appears that, whether you like it or not, if you invoke a JSP from a servlet, JSESSIONID will get created!

Added: I just found that by adding the following JSP directive:

<%@ page session="false" %>

you can disable the setting of JSESSIONID by a JSP.

I solve the problem opening the visual studio, expanding the references and changing the property "Copy Local" to "True".

I discover this comparing the dlls of the old version with the Dlls of my new version (that was not working)

Storage

Given numbers are only for storing 1 character

• ASCII ? 2⁷ bits (1 byte)
• Extended ASCII ? 2⁸ bits (1 byte)
• UTF-8 ? minimum 2⁸, maximum 2³² bits (min 1, max 4 bytes)
• UTF-16 ? minimum 2¹⁶, maximum 2³² bits (min 2, max 4 bytes)
• UTF-32 ? 2³² bits (4 bytes)

Usage (as of Feb 2020)

In the service project do the following:

1. In the solution explorer double click your services .cs file. It should bring up a screen that is all gray and talks about dragging stuff from the toolbox.
2. Then right click on the gray area and select add installer. This will add an installer project file to your project.
3. Then you will have 2 components on the design view of the ProjectInstaller.cs (serviceProcessInstaller1 and serviceInstaller1). You should then setup the properties as you need such as service name and user that it should run as.

Now you need to make a setup project. The best thing to do is use the setup wizard.

1. Right click on your solution and add a new project: Add > New Project > Setup and Deployment Projects > Setup Wizard

   a. This could vary slightly for different versions of Visual Studio. b. Visual Studio 2010 it is located in: Install Templates > Other Project Types > Setup and Deployment > Visual Studio Installer

2. On the second step select "Create a Setup for a Windows Application."

3. On the 3rd step, select "Primary output from..."

4. Click through to Finish.

Next edit your installer to make sure the correct output is included.

1. Right click on the setup project in your Solution Explorer.
2. Select View > Custom Actions. (In VS2008 it might be View > Editor > Custom Actions)
3. Right-click on the Install action in the Custom Actions tree and select 'Add Custom Action...'
4. In the "Select Item in Project" dialog, select Application Folder and click OK.
5. Click OK to select "Primary output from..." option. A new node should be created.
6. Repeat steps 4 - 5 for commit, rollback and uninstall actions.

You can edit the installer output name by right clicking the Installer project in your solution and select Properties. Change the 'Output file name:' to whatever you want. By selecting the installer project as well and looking at the properties windows, you can edit the Product Name, Title, Manufacturer, etc...

Next build your installer and it will produce an MSI and a setup.exe. Choose whichever you want to use to deploy your service.

Instead of comparing a maxima to the mean, one can also compare the maxima to adjacent minima where the minima are only defined above a noise threshold. If the local maximum is > 3 times (or other confidence factor) either adjacent minima, then that maxima is a peak. The peak determination is more accurate with wider moving windows. The above uses a calculation centered on the middle of the window, by the way, rather than a calculation at the end of the window (== lag).

Note that a maxima has to be seen as an increase in signal before and a decrease after.

This work for me:

 $('#data_compra').daterangepicker({
          singleDatePicker: true,
          locale: {
           format: 'DD/MM/YYYY'
          },
         calender_style: "picker_4", }, 
function(start, end, label) {
          console.log(start.toISOString(), end.toISOString(), label); 
});

This answer is centred on Java 8, and tries to cover all the details needed for the Java Professional Exam. It tries to explain why the different approaches exist. They each have their benefits, and each might be simplest in a given scenario.

Classes involved include:

.
+-- OutputStream
¦   +-- FileOutputStream
+-- Writer
¦   +-- OutputStreamWriter
¦   ¦   +-- FileWriter
¦   +-- BufferedWriter
¦   +-- PrintWriter (Java 5+)
+-- Files (Java 7+)

FileOutputStream

This class is meant for writing streams of raw bytes. All the Writer approaches below rely on this class, either explicitly or under the hood.

try (FileOutputStream stream = new FileOutputStream("file.txt");) {
    byte data[] = "foo".getBytes();
    stream.write(data);
} catch (IOException e) {}

Note that the try-with-resources statement takes care of stream.close() and that closing the stream flushes it, like stream.flush() (all of the examples below use this approach).

OutputStreamWriter

This class is a bridge from character streams to byte streams. It can wrap a FileOutputStream, and write strings:

Charset utf8 = StandardCharsets.UTF_8;
try (OutputStreamWriter writer = new OutputStreamWriter(new FileOutputStream(new File("file.txt")), utf8)) {
    writer.write("foo");
} catch (IOException e) {}

BufferedWriter

This class writes text to a character-output stream, buffering characters so as to provide for the efficient writing of single characters, arrays, and strings.

It can wrap an OutputStreamWriter:

try (BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(new File("file.txt"))))) {
    writer.write("foo");
    writer.newLine();  // method provided by BufferedWriter
} catch (IOException e) {}

Pre Java 5 this was the best approach for large files (with a regular try/catch block).

FileWriter

This is a subclass of the OutputStreamWriter, and is a convenience class for writing character files:

boolean append = false;
try(FileWriter writer = new FileWriter("file.txt", append) ){
    writer.write("foo");
    writer.append("bar");
} catch (IOException e) {}

The key benefit is that it has an optional append constructor argument, which determines whether it appends to or overwrites the existing file. Note that the append/overwrite behaviour is not controlled by the write() and append() methods, which behave in nearly the same way.

Note that:

• There is no buffering, but to handle large files it can be wrapped in a BufferedWriter.
• FileWriter uses the default encoding. It's often preferable to specify encoding explicitly

PrintWriter

This class prints formatted representations of objects to a text-output stream. Under the hood it is the same as the BufferedWriter approach above (new BufferedWriter(new OutputStreamWriter(new FileOutputStream(...)))). PrintWriter was introduced in Java 5 as a convenient way to call this idiom, and adds additional methods such as printf() and println().

Methods in this class don't throw I/O exceptions. You can check errors by calling checkError(). The destination of a PrintWriter instance can be a File, OutputStream or Writer. Here is an example of writing to a file:

try (PrintWriter writer = new PrintWriter("file.txt", "UTF-8")) {
    writer.print("foo");
    writer.printf("bar %d $", "a", 1);
    writer.println("baz");
} catch (FileNotFoundException e) {
} catch (UnsupportedEncodingException e) {}

When writing to an OutputStream or Writer there is an optional autoFlush constructor parameter, which is false by default. Unlike the FileWriter, it will overwrite any existing file.

Files.write()

Java 7 introduced java.nio.file.Files. Files.write() lets you create and write to a file in a single call.

@icza's answer shows how to use this method. A couple of examples:

Charset utf8 = StandardCharsets.UTF_8;
List<String> lines = Arrays.asList("foo", "bar");

try {
    Files.write(Paths.get("file.txt"), "foo".getBytes(utf8));
    Files.write(Paths.get("file2.txt"), lines, utf8);
} catch (IOException e) {}

This does not involve a buffer, so it's not suitable for large files.

Files.newBufferedWriter()

Java 7 also introduced Files.newBufferedWriter() which makes it easy to get a BufferedWriter:

Charset utf8 = StandardCharsets.UTF_8;
try (BufferedWriter writer = Files.newBufferedWriter(Paths.get("file.txt"), utf8)) {
    writer.write("foo");
} catch (IOException e) {}

This is similar to PrintWriter, with the downside of not having PrintWriter's methods, and the benefit that it doesn't swallow exceptions.

Even better:

enum choices {
   a1, a2, b1, b2;

  public static boolean contains(String s)
  {
      for(choices choice:values())
           if (choice.name().equals(s)) 
              return true;
      return false;
  } 

};

This short little snippet will do it, but I can't see it working with a nested hash. I think it's pretty cute though

STRING.gsub(/[{}:]/,'').split(', ').map{|h| h1,h2 = h.split('=>'); {h1 => h2}}.reduce(:merge)

Steps 1. I eliminate the '{','}' and the ':' 2. I split upon the string wherever it finds a ',' 3. I split each of the substrings that were created with the split, whenever it finds a '=>'. Then, I create a hash with the two sides of the hash I just split apart. 4. I am left with an array of hashes which I then merge together.

EXAMPLE INPUT: "{:user_id=>11, :blog_id=>2, :comment_id=>1}" RESULT OUTPUT: {"user_id"=>"11", "blog_id"=>"2", "comment_id"=>"1"}

Don't forget to add the schema name in case you have multiple schemas with the same table names.

SELECT column_name, data_type 
FROM information_schema.columns
WHERE table_name = 'your_table_name' AND table_schema = 'your_schema_name';

or using psql:

\d+ your_schema_name.your_table_name

This is a simple, you can use spring boot maven plugin to finish your code deploy.

the plugin config like:

<plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <jvmArguments>-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=${debug.port}
                    </jvmArguments>
                    <profiles>
                        <profile>test</profile>
                    </profiles>
                    <executable>true</executable>
                </configuration>
            </plugin>

And, the jvmArtuments is add for you jvm. profiles will choose a profile to start your app. executable can make your app driectly run.

and if you add mvnw to your project, or you have a maven enveriment. You can just call./mvnw spring-boot:run for mvnw or mvn spring-boot:run for maven.

Ironically, turning off AutoSize by setting it to false allowed me to get the label control dimensions to size it both vertically and horizontally which effectively allows word-wrapping to occur.

Our HTML:

<div id="addnew">
    <input type="text" id="id">
    <input type="text" id="content">
    <input type="button" value="Add" id="submit">
</div>

<div id="check">
    <input type="text" id="input">
    <input type="button" value="Search" id="search">
</div>

JS (writing to the txt file):

function writeToFile(d1, d2){
    var fso = new ActiveXObject("Scripting.FileSystemObject");
    var fh = fso.OpenTextFile("data.txt", 8, false, 0);
    fh.WriteLine(d1 + ',' + d2);
    fh.Close();
}
var submit = document.getElementById("submit");
submit.onclick = function () {
    var id      = document.getElementById("id").value;
    var content = document.getElementById("content").value;
    writeToFile(id, content);
}

checking a particular row:

function readFile(){
    var fso = new ActiveXObject("Scripting.FileSystemObject");
    var fh = fso.OpenTextFile("data.txt", 1, false, 0);
    var lines = "";
    while (!fh.AtEndOfStream) {
        lines += fh.ReadLine() + "\r";
    }
    fh.Close();
    return lines;
}
var search = document.getElementById("search");
search.onclick = function () {
    var input   = document.getElementById("input").value;
    if (input != "") {
        var text    = readFile();
        var lines   = text.split("\r");
        lines.pop();
        var result;
        for (var i = 0; i < lines.length; i++) {
            if (lines[i].match(new RegExp(input))) {
                result = "Found: " + lines[i].split(",")[1];
            }
        }
        if (result) { alert(result); }
        else { alert(input + " not found!"); }
    }
}

Put these inside a .hta file and run it. Tested on W7, IE11. It's working. Also if you want me to explain what's going on, say so.

To add to Jason's answer:

You can speed the process up (which might be helpful for very large exponents) using the binary expansion of the exponent. First calculate 5, 5^2, 5^4, 5^8 mod 221 - you do this by repeated squaring:

 5^1 = 5(mod 221)
 5^2 = 5^2 (mod 221) = 25(mod 221)
 5^4 = (5^2)^2 = 25^2(mod 221) = 625 (mod 221) = 183(mod221)
 5^8 = (5^4)^2 = 183^2(mod 221) = 33489 (mod 221) = 118(mod 221)
5^16 = (5^8)^2 = 118^2(mod 221) = 13924 (mod 221) = 1(mod 221)
5^32 = (5^16)^2 = 1^2(mod 221) = 1(mod 221)

Now we can write

55 = 1 + 2 + 4 + 16 + 32

so 5^55 = 5^1 * 5^2 * 5^4 * 5^16 * 5^32 
        = 5   * 25  * 625 * 1    * 1 (mod 221)
        = 125 * 625 (mod 221)
        = 125 * 183 (mod 183) - because 625 = 183 (mod 221)
        = 22875 ( mod 221)
        = 112 (mod 221)

You can see how for very large exponents this will be much faster (I believe it's log as opposed to linear in b, but not certain.)

Either you can change the button type to submit

<button type="submit"  onclick="submitform()" id="save">Save</button>

Or you can hide the submit button, keep another button with type="button" and have click event for that button

<form>
    <button style="display: none;" type="submit" >Hidden button</button>
    <button type="button" onclick="submitForm()">Submit</button>
</form>

To run the .bat, and have access to the last exit code, run it as:

• because when the constructor is called, the bean is not yet initialized - i.e. no dependencies are injected. In the @PostConstruct method the bean is fully initialized and you can use the dependencies.

• because this is the contract that guarantees that this method will be invoked only once in the bean lifecycle. It may happen (though unlikely) that a bean is instantiated multiple times by the container in its internal working, but it guarantees that @PostConstruct will be invoked only once.

In C++, variable length arrays are not legal. G++ allows this as an "extension" (because C allows it), so in G++ (without being -pedantic about following the C++ standard), you can do:

int n = 10;
double a[n]; // Legal in g++ (with extensions), illegal in proper C++

If you want a "variable length array" (better called a "dynamically sized array" in C++, since proper variable length arrays aren't allowed), you either have to dynamically allocate memory yourself:

int n = 10;
double* a = new double[n]; // Don't forget to delete [] a; when you're done!

Or, better yet, use a standard container:

int n = 10;
std::vector<double> a(n); // Don't forget to #include <vector>

If you still want a proper array, you can use a constant, not a variable, when creating it:

const int n = 10;
double a[n]; // now valid, since n isn't a variable (it's a compile time constant)

Similarly, if you want to get the size from a function in C++11, you can use a constexpr:

constexpr int n()
{
    return 10;
}

double a[n()]; // n() is a compile time constant expression

For anyone stumbling on this question, here is the answer if you are doing C++: You can check in your cpp code for vs version like the example bellow which links against a library based on vs version being 2015 or higher:

#if (_MSC_VER > 1800)
#pragma comment (lib, "legacy_stdio_definitions.lib")
#endif

This is done at link time and no extra run-time cost.

  <head>
    <script type="text/javascript" src="jquery.js"></script>

      $(document).ready(function(){
        var locations = ["http://webPage1.com", "http://webPage2.com"];
        var len = locations.length;
        var iframe = $('#frame');
        var i = 0;
        setInterval(function () {
            iframe.attr('src', locations[++i % len]);
        }, 30000);
      });

Or you can use regular expression to handle multiple items as the general case of this issue,

df['2nd'] = pd.to_numeric(df['2nd'].str.replace(r'[,.%]','')) 
df['CTR'] = pd.to_numeric(df['CTR'].str.replace(r'[^\d%]',''))

If you're using another utility that passes a single argument to grep, you can use:

'[-]X'

impossible with javascript. Just as another alternative to suggestions from other answers: consider using jGrowl: http://archive.plugins.jquery.com/project/jGrowl

To get capitalized keyboard when click edittext use this code in your xml,

<EditText
    android:id="@+id/et"
    android:layout_width="250dp"
    android:layout_height="wrap_content"
    android:hint="Input your country"
    android:padding="10dp"
    android:inputType="textCapCharacters"
    />

For me, it helped to count the number of values per group. Copy the count table into a new object. Then filter for the max of the group based on the first grouping characteristic. For example:

count_table  <- df %>%
                group_by(A, B) %>%
                count() %>%
                arrange(A, desc(n))

count_table %>% 
    group_by(A) %>%
    filter(n == max(n))

or

count_table %>% 
    group_by(A) %>%
    top_n(1, n)

I have used Fredrik's code above in a project with some slight modifications, thought I'd share:

private static bool DownloadRemoteImageFile(string uri, string fileName)
{
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uri);
    HttpWebResponse response;
    try
    {
        response = (HttpWebResponse)request.GetResponse();
    }
    catch (Exception)
    {
        return false;
    }

    // Check that the remote file was found. The ContentType
    // check is performed since a request for a non-existent
    // image file might be redirected to a 404-page, which would
    // yield the StatusCode "OK", even though the image was not
    // found.
    if ((response.StatusCode == HttpStatusCode.OK ||
        response.StatusCode == HttpStatusCode.Moved ||
        response.StatusCode == HttpStatusCode.Redirect) &&
        response.ContentType.StartsWith("image", StringComparison.OrdinalIgnoreCase))
    {

        // if the remote file was found, download it
        using (Stream inputStream = response.GetResponseStream())
        using (Stream outputStream = File.OpenWrite(fileName))
        {
            byte[] buffer = new byte[4096];
            int bytesRead;
            do
            {
                bytesRead = inputStream.Read(buffer, 0, buffer.Length);
                outputStream.Write(buffer, 0, bytesRead);
            } while (bytesRead != 0);
        }
        return true;
    }
    else
        return false;
}

Main changes are:

• using a try/catch for the GetResponse() as I was running into an exception when the remote file returned 404
• returning a boolean

A few comments:

import sun.misc.*; Don't do this. It is non-standard and not guaranteed to be the same between implementations. There are other libraries with Base64 conversion available.

byte[] encVal = c.doFinal(Data.getBytes()); You are relying on the default character encoding here. Always specify what character encoding you are using: byte[] encVal = c.doFinal(Data.getBytes("UTF-8")); Defaults might be different in different places.

As @thegrinner pointed out, you need to explicitly check the length of your byte arrays. If there is a discrepancy, then compare them byte by byte to see where the difference is creeping in.

It does work indeed. Issue was with my less compiler. It was compiled in to:

.container {
  min-height: calc(-51vh);
}

Fixed with the following code in less file:

.container {
  min-height: calc(~"100vh - 150px");
}

Thanks to this link: Less Aggressive Compilation with CSS3 calc

I believe that I have the simplest answer. You don't need the string.h library in this program, nor the stdbool.h library. Simply using pointers and pointer arithmetic will help you become a better C programmer.

Simply return 0 for False (no substring found), or 1 for True (yes, a substring "sub" is found within the overall string "str"):

#include <stdlib.h>

int is_substr(char *str, char *sub)
{
  int num_matches = 0;
  int sub_size = 0;
  // If there are as many matches as there are characters in sub, then a substring exists.
  while (*sub != '\0') {
    sub_size++;
    sub++;
  }

  sub = sub - sub_size;  // Reset pointer to original place.
  while (*str != '\0') {
    while (*sub == *str && *sub != '\0') {
      num_matches++;
      sub++;
      str++;
    }
    if (num_matches == sub_size) {
      return 1;
    }
    num_matches = 0;  // Reset counter to 0 whenever a difference is found. 
    str++;
  }
  return 0;
}

I solved this by adding email accounts in Cpanel and also adding that same email to the header from field like this

$header = 'From: XXXXXXXX <[email protected]>' . "\r\n";

Network communication Host -> Guest

Connect to the Guest and find out the ip address:

ifconfig 

example of result (ip address is 10.0.2.15):

eth0      Link encap:Ethernet  HWaddr 08:00:27:AE:36:99
          inet addr:10.0.2.15  Bcast:10.0.2.255  Mask:255.255.255.0

Go to Vbox instance window -> Menu -> Network adapters:

• adapter should be NAT
• click on "port forwarding"
• insert new record (+ icon)
  • for host ip enter 127.0.0.1, and for guest ip address you got from prev. step (in my case it is 10.0.2.15)
  • in your case port is 8000 - put it on both, but you can change host port if you prefer

Go to host system and try it in browser:

http://127.0.0.1:8000

or your network ip address (find out on the host machine by running: ipconfig).

Network communication Guest -> Host

In this case port forwarding is not needed, the communication goes over the LAN back to the host.

On the host machine - find out your netw ip address:

ipconfig

example of result:

IP Address. . . . . . . . . . . . : 192.168.5.1

On the guest machine you can communicate directly with the host, e.g. check it with ping:

# ping 192.168.5.1
PING 192.168.5.1 (192.168.5.1) 56(84) bytes of data.
64 bytes from 192.168.5.1: icmp_seq=1 ttl=128 time=2.30 ms
...

Firewall issues?

@Stranger suggested that in some cases it would be necessary to open used port (8000 or whichever is used) in firewall like this (example for ufw firewall, I haven't tested):

sudo ufw allow 8000 

Since aa is the set/object that might be null, can you check aa == null ?

(aa / xx might be interchangeable (a typo in the question); the original question talks about xx but only defines aa)

i.e.

select new {
    AssetID = x.AssetID,
    Status = aa == null ? (bool?)null : aa.Online; // a Nullable<bool>
}

or if you want the default to be false (not null):

select new {
    AssetID = x.AssetID,
    Status = aa == null ? false : aa.Online;
}

Update; in response to the downvote, I've investigated more... the fact is, this is the right approach! Here's an example on Northwind:

        using(var ctx = new DataClasses1DataContext())
        {
            ctx.Log = Console.Out;
            var qry = from boss in ctx.Employees
                      join grunt in ctx.Employees
                          on boss.EmployeeID equals grunt.ReportsTo into tree
                      from tmp in tree.DefaultIfEmpty()
                      select new
                             {
                                 ID = boss.EmployeeID,
                                 Name = tmp == null ? "" : tmp.FirstName
                        };
            foreach(var row in qry)
            {
                Console.WriteLine("{0}: {1}", row.ID, row.Name);
            }
        }

And here's the TSQL - pretty much what we want (it isn't ISNULL, but it is close enough):

SELECT [t0].[EmployeeID] AS [ID],
    (CASE
        WHEN [t2].[test] IS NULL THEN CONVERT(NVarChar(10),@p0)
        ELSE [t2].[FirstName]
     END) AS [Name]
FROM [dbo].[Employees] AS [t0]
LEFT OUTER JOIN (
    SELECT 1 AS [test], [t1].[FirstName], [t1].[ReportsTo]
    FROM [dbo].[Employees] AS [t1]
    ) AS [t2] ON ([t0].[EmployeeID]) = [t2].[ReportsTo]

QED?

None of the above answers worked for me due to their specified attachment format (application/octet-stream). Use application/pdf for best results with PDF files.

<?php

// just edit these 
$to          = "[email protected], [email protected]"; // addresses to email pdf to
$from        = "[email protected]"; // address message is sent from
$subject     = "Your PDF email subject"; // email subject
$body        = "<p>The PDF is attached.</p>"; // email body
$pdfLocation = "./your-pdf.pdf"; // file location
$pdfName     = "pdf-file.pdf"; // pdf file name recipient will get
$filetype    = "application/pdf"; // type

// creates headers and mime boundary
$eol = PHP_EOL;
$semi_rand     = md5(time());
$mime_boundary = "==Multipart_Boundary_$semi_rand";
$headers       = "From: $from$eolMIME-Version: 1.0$eol" .
    "Content-Type: multipart/mixed;$eol boundary=\"$mime_boundary\"";

// add html message body
$message = "--$mime_boundary$eol" .
    "Content-Type: text/html; charset=\"iso-8859-1\"$eol" .
    "Content-Transfer-Encoding: 7bit$eol$eol$body$eol";

// fetches pdf
$file = fopen($pdfLocation, 'rb');
$data = fread($file, filesize($pdfLocation));
fclose($file);
$pdf = chunk_split(base64_encode($data));

// attaches pdf to email
$message .= "--$mime_boundary$eol" .
    "Content-Type: $filetype;$eol name=\"$pdfName\"$eol" .
    "Content-Disposition: attachment;$eol filename=\"$pdfName\"$eol" .
    "Content-Transfer-Encoding: base64$eol$eol$pdf$eol--$mime_boundary--";

// Sends the email
if(mail($to, $subject, $message, $headers)) {
    echo "The email was sent.";
}
else {
    echo "There was an error sending the mail.";
}

In python 3, we can use below method.

Read from file and convert to JSON

import json
from pprint import pprint

# Considering "json_list.json" is a json file

with open('json_list.json') as fd:
     json_data = json.load(fd)
     pprint(json_data)

with statement automatically close the opened file descriptor.

String to JSON

import json
from pprint import pprint

json_data = json.loads('{"name" : "myName", "age":24}')
pprint(json_data)

I used the answer of NM Pennypacker and installed vim via homebrew for an early 2011 MacBook Pro:

brew install vim

Now I can also use the "* register to copy and paste text within vim. I even didn't have to change something within my ~/.vimrc file or the $PATH. Homebrew added symlinks in /usr/local/bin, e.g. vim -> ../Cellar/vim/8.1.2350/bin/vim.

The alternative, which worked before, is to copy some lines of text within vim by marking it with the mouse and using copy and paste (cmd + c, cmd + v) on a mac. This option only works if the text you want to copy and paste is less in size than the window size of vim. If you want to copy all text within vim by marking the whole window or using cmd + a, this will copy other parts of the console, written before starting vim, which is very annoying.

So, I am happy having found the new method using the clippboard register.

The ready event is always execute at the only html page is loaded to the browser and the functions are executed.... But the load event is executed at the time of all the page contents are loaded to the browser for the page..... we can use $ or jQuery when we use the noconflict() method in jquery scripts...

<c:if test="${fn:contains(task.subscribers, customer)}">

This works fine for me.

Step 1 Included the cdn like

     <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>

     <script src="http://ajax.aspnetcdn.com/ajax/jquery.validate/1.11.1/jquery.validate.min.js"></script>

Step 2 Code Like

  $(document).ready(function(){
        $("#submit").click(function () {
              $('#myform').validate({ // initialize the plugin
                rules: {
                    id: {
                        required: true,
                        email: true
                    },
                    password: {
                        required: true,
                        minlength: 1
                    }
                },
                messages: {
                    id: {
                        required: "Enter Email Id"

                    },
                    password: {
                        required: "Enter Email Password"

                    }
                },
                submitHandler: function (form) { // for demo
                    alert('valid form submitted'); // for demo
                    return false; // for demo
                }
            });
       }):
  }); 

here is the example using Pure JavaScript

function scrollpage() {  _x000D_
 function f() _x000D_
 {_x000D_
  window.scrollTo(0,i);_x000D_
  if(status==0) {_x000D_
      i=i+40;_x000D_
   if(i>=Height){ status=1; } _x000D_
  } else {_x000D_
   i=i-40;_x000D_
   if(i<=1){ status=0; }  // if you don't want continue scroll then remove this line_x000D_
  }_x000D_
 setTimeout( f, 0.01 );_x000D_
 }f();_x000D_
}_x000D_
var Height=document.documentElement.scrollHeight;_x000D_
var i=1,j=Height,status=0;_x000D_
scrollpage();_x000D_
</script>

<style type="text/css">_x000D_
_x000D_
 #top { border: 1px solid black;  height: 20000px; }_x000D_
 #bottom { border: 1px solid red; }_x000D_
_x000D_
</style>

<div id="top">top</div>_x000D_
<div id="bottom">bottom</div>

Here is my solution:

AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Select The Difficulty Level");
builder.setCancelable(false);

You can check console output. It prints error:

The following assertion was thrown during performResize(): Horizontal viewport was given unbounded height. Viewports expand in the cross axis to fill their container and constrain their children to match their extent in the cross axis. In this case, a horizontal viewport was given an unlimited amount of vertical space in which to expand.

You need to add height constraint to your horizontal list. E.g. wrap in Container with height:

Container(
  height: 44.0,
  child: ListView(
    scrollDirection: Axis.horizontal,
    children: <Widget>[
      RaisedButton(
        onPressed: null,
        child: Text("Facebook"),
      ),
      Padding(padding: EdgeInsets.all(5.00)),
      RaisedButton(
        onPressed: null,
        child: Text("Google"),
      )
    ],
  ),
)

There are at least three places where you may find shared_ptr:

1. If your C++ implementation supports C++11 (or at least the C++11 shared_ptr), then std::shared_ptr will be defined in <memory>.

2. If your C++ implementation supports the C++ TR1 library extensions, then std::tr1::shared_ptr will likely be in <memory> (Microsoft Visual C++) or <tr1/memory> (g++'s libstdc++). Boost also provides a TR1 implementation that you can use.

3. Otherwise, you can obtain the Boost libraries and use boost::shared_ptr, which can be found in <boost/shared_ptr.hpp>.

I also favor the RegEx solution. The code will be much cleaner. I would hesitate to use toLowerCase() in situations where I knew the strings were going to be large, since strings are immutable and would have to be copied. Also, the matches() solution might be confusing because it takes a regular expression as an argument (searching for "Need$le" cold be problematic).

Building on some of the above examples:

public boolean containsIgnoreCase( String haystack, String needle ) {
  if(needle.equals(""))
    return true;
  if(haystack == null || needle == null || haystack .equals(""))
    return false; 

  Pattern p = Pattern.compile(needle,Pattern.CASE_INSENSITIVE+Pattern.LITERAL);
  Matcher m = p.matcher(haystack);
  return m.find();
}

example call: 

String needle = "Need$le";
String haystack = "This is a haystack that might have a need$le in it.";
if( containsIgnoreCase( haystack, needle) ) {
  System.out.println( "Found " + needle + " within " + haystack + "." );
}

(Note: you might want to handle NULL and empty strings differently depending on your needs. I think they way I have it is closer to the Java spec for strings.)

Speed critical solutions could include iterating through the haystack character by character looking for the first character of the needle. When the first character is matched (case insenstively), begin iterating through the needle character by character, looking for the corresponding character in the haystack and returning "true" if all characters get matched. If a non-matched character is encountered, resume iteration through the haystack at the next character, returning "false" if a position > haystack.length() - needle.length() is reached.

UPDATED:
Matt provided a great link on how to add emulators for all Samsung devices.

OLD:
To get the official Samsung Galaxy Tab emulator do the following:

1. Open the Android SDK and AVD Manager
2. Click on Available packages
3. Expand the Third party Add-ons. There you will see Samsung Electronics add-ons.
4. Once the add-on is installed create a new emulator. Under Target you will see the new Samsung Tab settings, select that.

That's it!

In general, you implement the ICloneable interface and implement Clone yourself. C# objects have a built-in MemberwiseClone method that performs a shallow copy that can help you out for all the primitives.

For a deep copy, there is no way it can know how to automatically do it.

Looking more closely at my web.config set up, one of the comments in this post is very helpful

in asp.net 3.5 sp1 there is a new parameter redirectMode

So we can amend customErrors to add this parameter:

<customErrors mode="RemoteOnly" defaultRedirect="~/errors/GeneralError.aspx" redirectMode="ResponseRewrite" />

the ResponseRewrite mode allows us to load the «Error Page» without redirecting the browser, so the URL stays the same, and importantly for me, exception information is not lost.

Actually, it doesn't really work. You can find an explanation in one of the comments in the manual page: http://www.php.net/manual/en/features.file-upload.php#74692

Answer to updated question: the obvious difference is that server-side checks are reliable, client-side checks are not.

we can groupby the 'name' and 'month' columns, then call agg() functions of Panda’s DataFrame objects.

The aggregation functionality provided by the agg() function allows multiple statistics to be calculated per group in one calculation.

df.groupby(['name', 'month'], as_index = False).agg({'text': ' '.join})

They are the same thing, aren't they?

No, they aren't.

I think the first sentence of the Wikipedia page you referenced gives a nice, brief summary:

UTF-8 is a variable width character encoding capable of encoding all 1,112,064 valid code points in Unicode using one to four 8-bit bytes.

To elaborate:

• Unicode is a standard, which defines a map from characters to numbers, the so-called code points, (like in the example below). For the full mapping, you can have a look here.

  ! -> U+0021 (21),  
  " -> U+0022 (22),  
  \# -> U+0023 (23)
  

• UTF-8 is one of the ways to encode these code points in a form a computer can understand, aka bits. In other words, it's a way/algorithm to convert each of those code points to a sequence of bits or convert a sequence of bits to the equivalent code points. Note that there are a lot of alternative encodings for Unicode.

Joel gives a really nice explanation and an overview of the history here.

@memical had an awesome solution for setting the height of the textarea on pageload with jQuery, but for my application I wanted to be able to increase the height of the textarea as the user added more content. I built off memical's solution with the following:

$(document).ready(function() {
    var $textarea = $("p.body textarea");
    $textarea.css("height", ($textarea.attr("scrollHeight") + 20));
    $textarea.keyup(function(){
        var current_height = $textarea.css("height").replace("px", "")*1;
        if (current_height + 5 <= $textarea.attr("scrollHeight")) {
            $textarea.css("height", ($textarea.attr("scrollHeight") + 20));
        }
    });
});

It's not very smooth but it's also not a client-facing application, so smoothness doesn't really matter. (Had this been client-facing, I probably would have just used an auto-resize jQuery plugin.)

JPEG is not the lightest for all kinds of images(or even most). Corners and straight lines and plain "fills"(blocks of solid color) will appear blurry or have artifacts in them depending on the compression level. It is a lossy format, and works best for photographs where you can't see artifacts clearly. Straight lines(such as in drawings and comics and such) compress very nicely in PNG and it's lossless. GIF should only be used when you want transparency to work in IE6 or you want animation. GIF only supports a 256 color pallete but is also lossless.

So basically here is a way to decide the image format:

• GIF if needs animation or transparency that works on IE6(note, PNG transparency works after IE6)
• JPEG if the image is a photograph.
• PNG if straight lines as in a comic or other drawing or if a wide color range is needed with transparency(and IE6 is not a factor)

And as commented, if you are unsure of what would qualify, try each format with different compression ratios and weigh the quality and size of the picture and choose which one you think is best. I am only giving rules of thumb.

To be precise,

Thread.isAlive() returns true if the thread has been started (may not yet be running) but has not yet completed its run method.

Thread.getState() returns the exact state of the thread.

From the docs

IF boolean-expression THEN

END IF;

So in your above example the code should look as follows:

IF select count(*) from orders > 0
THEN
  DELETE from orders
ELSE 
  INSERT INTO orders values (1,2,3);
END IF;

You were missing: END IF;

I would recommend using isFile() instead of exists(). Most of the time you are looking to check if the path points to a file not only that it exists. Remember that exists() will return true if your path points to a directory.

new File("path/to/file.txt").isFile();

new File("C:/").exists() will return true but will not allow you to open and read from it as a file.

This coffeescript works for me with Node - the trick is that the _id get's stripped of its ObjectID wrapper when sent and returned from the client and so this needs to be replaced for updates (when no _id is provided, save will revert to insert and add one).

app.post '/new', (req, res) ->
    # post data becomes .query
    data = req.query
    coll = db.collection 'restos'
    data._id = ObjectID(data._id) if data._id

    coll.save data, {safe:true}, (err, result) ->
        console.log("error: "+err) if err
        return res.send 500, err if err

        console.log(result)
        return res.send 200, JSON.stringify result

Just a reminder you can't initialise DataTable on the same <table> element twice.

If you encounter same issue then you can set searching and paging false while initializing DataTable on your HTML <table> like this

 $('#tbl').DataTable({
    searching: false, 
    paging: false,
    dom: 'Bfrtip',
    buttons: [
       'copy', 'csv', 'excel', 'pdf', 'print'
    ]
 });

According to the ant manual, setting JAVA_HOME should work - are you sure the changed setting is visible to ant?

Alternatively, you could use the JAVACMD variable.

This tree is not a binary tree, so you need an array of the children elements, like List.

public Node(Object data, List<Node> children) {
    this.data = data;
    this.children = children;
}

Then create the instances.

I am not sure whether the database backup file, you trying to restore, is coming from the same environment as you trying to restore it onto.

Remember that destination path of .mdf and .ldf files lives with the backup file itself.

If this is not a case, that means the backup file is coming from a different environment from your current hosting one, make sure that .mdf and .ldf file path is the same (exists) as on your machine, relocate these otherwise. (Mostly a case of restoring db in Docker image)

The way how to do it: In Databases -> Restore database -> [Files] option -> (Check "Relocate all files to folder" - mostly default path is populated on your hosting environment already)

string[][] is not a two-dimensional array, it's an array of arrays (a jagged array). That's something different.

To declare a two-dimensional array, use this syntax:

string[,] tablero = new string[3, 3];

If you really want a jagged array, you need to initialize it like this:

string[][] tablero = new string[][] { new string[3], 
                                      new string[3], 
                                      new string[3] };

The data dictionary table DBA_SYNONYMS has information about all the synonyms in a database. So you can run the query

SELECT table_owner, table_name, db_link
  FROM dba_synonyms 
 WHERE owner        = 'PUBLIC'
   AND synonym_name = <<synonym name>>

to see what the public synonym currently points at.

Temporarily changing dirs works well for importing:

cwd = os.getcwd()
os.chdir(<module_path>)
import <module>
os.chdir(cwd)

Remember when you used to sum, for example 2 & 3, in your old calculator and every time you hit the = you see 3 added to the total, the += does similar job. Example:

>>> orange = 2
>>> orange += 3
>>> print(orange)
5
>>> orange +=3
>>> print(orange)
8

Note that it is now possible to use some of C++11 std::thread in the win32 threading mode. These header-only adapters worked out of the box for me: https://github.com/meganz/mingw-std-threads

From the revision history it looks like there is some recent attempt to make this a part of the mingw64 runtime.

    $.validator.methods.checkEmail = function( value, element ) {
        return this.optional( element ) || /[a-z]+@[a-z]+\.[a-z]+/.test( value );
    }

    $("#myForm").validate({
        rules: {
            email: {
                required: true,
                checkEmail: true
            }
        },
        messages: {
            email: "incorrect email"
        }
    });

I have uninstalled 8.0.19 (64) and installed 8.0.18 (64 bit) and now it Opens.

As said, there's no way. However, a bit decent IDE can autogenerate delegate methods. For example Eclipse can do. First setup a template:

public class MultipleInterfaces implements InterFaceOne, InterFaceTwo {
    private InterFaceOne if1;
    private InterFaceTwo if2;
}

then rightclick, choose Source > Generate Delegate Methods and tick the both if1 and if2 fields and click OK.

See also the following screens:

curl's --data will by default send Content-Type: application/x-www-form-urlencoded in the request header. However, when using Postman's raw body mode, Postman sends Content-Type: text/plain in the request header.

So to achieve the same thing as Postman, specify -H "Content-Type: text/plain" for curl:

curl -X POST -H "Content-Type: text/plain" --data "this is raw data" http://78.41.xx.xx:7778/

Note that if you want to watch the full request sent by Postman, you can enable debugging for packed app. Check this link for all instructions. Then you can inspect the app (right-click in Postman) and view all requests sent from Postman in the network tab :

This should do the trick

df = data.frame(date=c("2012-02-01", "2012-02-01", "2012-02-02")) 
dow <- function(x) format(as.Date(x), "%A")
df$day <- dow(df$date)
df

#Returns:
        date       day
1 2012-02-01 Wednesday
2 2012-02-01 Wednesday
3 2012-02-02  Thursday

Your second example does not work if you send the argument by reference. Did you mean

void copyVecFast(vec<int> original) // no reference
{

  vector<int> new_;
  new_.swap(original); 
}

That would work, but an easier way is

vector<int> new_(original);

The div doesn't take up all the available horizontal space when absolutely positioned. Explicitly setting the width to 100% will solve the problem:

HTML

<div id="my-div">I want to be centered</div>?

CSS

#my-div {
   position: absolute;
   bottom: 15px;
   text-align: center;
   width: 100%;
}

?

Another solutions (works with TCPDF)

Use HEREDOC for a long string. Put HERDOC for a CONST for example (define different languages)

$_prepare_const_EN = <<<EOT
this is a long string
and new line as well ...
EOT;

$define('STR_EN', $_prepare_const_EN);

$pdf->InsertText(STR_EN);

works for me wery well....

Adding to the above-accepted answer so that it helps those who are using tensorflow 2.0

import tensorflow as tf

# some data
c1 = tf.constant([[1, 1, 1], [2, 2, 2]], dtype=tf.float32)
c2 = tf.constant([[2, 2, 2], [3, 3, 3]], dtype=tf.float32)
c3 = tf.constant([[3, 3, 3], [4, 4, 4]], dtype=tf.float32)

# bake layers x1, x2, x3
x1 = tf.keras.layers.Dense(10)(c1)
x2 = tf.keras.layers.Dense(10)(c2)
x3 = tf.keras.layers.Dense(10)(c3)

# merged layer y1
y1 = tf.keras.layers.Concatenate(axis=1)([x1, x2])

# merged layer y2
y2 = tf.keras.layers.Concatenate(axis=1)([y1, x3])

# print info
print("-"*30)
print("x1", x1.shape, "x2", x2.shape, "x3", x3.shape)
print("y1", y1.shape)
print("y2", y2.shape)
print("-"*30)

Result:

------------------------------
x1 (2, 10) x2 (2, 10) x3 (2, 10)
y1 (2, 20)
y2 (2, 30)
------------------------------

You must have a server-side script to handle your request, it can't be done using javascript.

To send raw data without URIencoding or escaping special characters to the php and save it as new txt file you can send ajax request using post method and FormData like:

JS:

var data = new FormData();
data.append("data" , "the_text_you_want_to_save");
var xhr = (window.XMLHttpRequest) ? new XMLHttpRequest() : new activeXObject("Microsoft.XMLHTTP");
xhr.open( 'post', '/path/to/php', true );
xhr.send(data);

PHP:

if(!empty($_POST['data'])){
$data = $_POST['data'];
$fname = mktime() . ".txt";//generates random name

$file = fopen("upload/" .$fname, 'w');//creates new file
fwrite($file, $data);
fclose($file);
}

Edit:

As Florian mentioned below, the XHR fallback is not required since FormData is not supported in older browsers (formdata browser compatibiltiy), so you can declare XHR variable as:

var xhr = new XMLHttpRequest();

Also please note that this works only for browsers that support FormData such as IE +10.

<select id="message_tag">
<optgroup>
<option>

</optgroup>

here i just removed bootstrap css for only "select" element. using following css code.

#message_tag_chzn{
display: none;
}

 #message_tag{
  display: inline !important;
}

These specific lines are the usual wrapper for jQuery plugins:

"...to make sure that your plugin doesn't collide with other libraries that might use the dollar sign, it's a best practice to pass jQuery to a self executing function (closure) that maps it to the dollar sign so it can't be overwritten by another library in the scope of its execution."

(function( $ ){
  $.fn.myPlugin = function() {
    // Do your awesome plugin stuff here
  };
})( jQuery );

Simplest Node.js server is just:

$ npm install http-server -g

Now you can run a server via the following commands:

$ cd MyApp

$ http-server

If you're using NPM 5.2.0 or newer, you can use http-server without installing it with npx. This isn't recommended for use in production but is a great way to quickly get a server running on localhost.

$ npx http-server

Or, you can try this, which opens your web browser and enables CORS requests:

$ http-server -o --cors

For more options, check out the documentation for http-server on GitHub, or run:

$ http-server --help

Lots of other nice features and brain-dead-simple deployment to NodeJitsu.

Feature Forks

Of course, you can easily top up the features with your own fork. You might find it's already been done in one of the existing 800+ forks of this project:

• https://github.com/nodeapps/http-server/network

Light Server: An Auto Refreshing Alternative

A nice alternative to http-server is light-server. It supports file watching and auto-refreshing and many other features.

$ npm install -g light-server 
$ light-server

Add to your directory context menu in Windows Explorer

 reg.exe add HKCR\Directory\shell\LightServer\command /ve /t REG_EXPAND_SZ /f /d "\"C:\nodejs\light-server.cmd\" \"-o\" \"-s\" \"%V\""

Simple JSON REST server

If you need to create a simple REST server for a prototype project then json-server might be what you're looking for.

Auto Refreshing Editors

Most web page editors and IDE tools now include a web server that will watch your source files and auto refresh your web page when they change.

I use Live Server with Visual Studio Code.

The open source text editor Brackets also includes a NodeJS static web server. Just open any HTML file in Brackets, press "Live Preview" and it starts a static server and opens your browser at the page. The browser will **auto refresh whenever you edit and save the HTML file. This especially useful when testing adaptive web sites. Open your HTML page on multiple browsers/window sizes/devices. Save your HTML page and instantly see if your adaptive stuff is working as they all auto refresh.

PhoneGap Developers

If you're coding a hybrid mobile app, you may be interested to know that the PhoneGap team took this auto refresh concept on board with their new PhoneGap App. This is a generic mobile app that can load the HTML5 files from a server during development. This is a very slick trick since now you can skip the slow compile/deploy steps in your development cycle for hybrid mobile apps if you're changing JS/CSS/HTML files — which is what you're doing most of the time. They also provide the static NodeJS web server (run phonegap serve) that detects file changes.

PhoneGap + Sencha Touch Developers

I've now extensively adapted the PhoneGap static server & PhoneGap Developer App for Sencha Touch & jQuery Mobile developers. Check it out at Sencha Touch Live. Supports --qr QR Codes and --localtunnel that proxies your static server from your desktop computer to a URL outside your firewall! Tons of uses. Massive speedup for hybrid mobile devs.

Cordova + Ionic Framework Developers

Local server and auto refresh features are baked into the ionic tool. Just run ionic serve from your app folder. Even better ... ionic serve --lab to view auto-refreshing side by side views of both iOS and Android.

To diagnose better, you can capture the standard output and standard error streams of the external program, in order to see what output was generated and why it might not be running as expected.

Look up:

• ProcessStartInfo.RedirectStandardError and
• ProcessStartInfo.RedirectStandardOutput.

If you set each of those to true, then you can later call process.StandardOutput.ReadToEnd() and process.StandardError.ReadToEnd() to get the output into string variables, which you can easily inspect under the debugger, or output to trace or your log file.

A good plugin that I have used before is DataTables.

Easiest way: You should create a new emulator, before opening it for the first time follow these 3 easy steps:

1- go to C:\Users[user].android\avd[your virtual device folder] open "config.ini" with text editor like notepad

2- change

"PlayStore.enabled=false" to "PlayStore.enabled=true"

3- change

mage.sysdir.1 = system-images\android-30\google_apis\x86\

to

image.sysdir.1 = system-images\android-30\google_apis_playstore\x86\

I ran the code below, once with foo taking the shared_ptr by const& and again with foo taking the shared_ptr by value.

void foo(const std::shared_ptr<int>& p)
{
    static int x = 0;
    *p = ++x;
}

int main()
{
    auto p = std::make_shared<int>();
    auto start = clock();
    for (int i = 0; i < 10000000; ++i)
    {
        foo(p);
    }    
    std::cout << "Took " << clock() - start << " ms" << std::endl;
}

Using VS2015, x86 release build, on my intel core 2 quad (2.4GHz) processor

const shared_ptr&     - 10ms  
shared_ptr            - 281ms 

The copy by value version was an order of magnitude slower.
If you are calling a function synchronously from the current thread, prefer the const& version.

Older versions of git allowed you to use the "theirs" merge strategy:

git pull --strategy=theirs remote_branch

But this has since been removed, as explained in this message by Junio Hamano (the Git maintainer). As noted in the link, instead you would do this:

git fetch origin
git reset --hard origin

Beware, though, that this is different than an actual merge. Your solution is probably the option you're really looking for.

@(ViewContext.RouteData.Values["parameterName"])

Request.Params["paramName"]

I collected together scripts from my web scraping work into this bit-bucket library.

Example script for your case:

from webscraping import download, xpath
D = download.Download()

html = D.get('http://example.com')
for row in xpath.search(html, '//table[@class="spad"]/tbody/tr'):
    cols = xpath.search(row, '/td')
    print 'Sunrise: %s, Sunset: %s' % (cols[1], cols[2])

Output:

Sunrise: 08:39, Sunset: 16:08
Sunrise: 08:39, Sunset: 16:09
Sunrise: 08:39, Sunset: 16:10
Sunrise: 08:40, Sunset: 16:10
Sunrise: 08:40, Sunset: 16:11
Sunrise: 08:40, Sunset: 16:12
Sunrise: 08:40, Sunset: 16:13

Have you renamed your project/main class (e.g. through refactoring) ? If yes your Launch Configuration might be set up incorrectly (e.g. refering to the old main class or configuration). Even though the project name appears in the 'export runnable jar' dialog, a closer inspection might reveal an unmatched main class name.

Go to 'Properties->Run/Debug Settings' of your project and make sure your Launch Configuration (the same used to export runnable jar) is set to the right name of project AND your main class is set to name.space.of.your.project/YouMainClass.

try:

Activity parentActivity = this.getParent();
if (parentActivity != null)
{
    View landmarkEditNameView = (EditText) parentActivity.findViewById(R.id. landmark_name_dialog_edit);
}

Or use somthing like this:

var MiniScroll=function(a,b){function e(){c.scrollUpdate()}function f(){var a=new Date,b=Math.abs(a-c.animation.frame),d=c.countScrollHeight();c.animation.frame=a,c.render(b),d.height!=c.controls.height&&(e(),c.controls.height=d.height),requestAnimationFrame(f)}function g(){c.scrollUpdate()}function h(a){var b=c.target.scrollTop,d=Math.abs(a.wheelDeltaY/(10-c.speed));c.target.scrollTop=a.wheelDeltaY>0?b-d:b+d,c.scrollUpdate()}function i(a){if(a.target.classList.contains("scroll"))return a.preventDefault(),!1;var b=c.countScrollHeight();c.target.scrollTop=a.offsetY*b.mul-parseInt(b.height)/2,c.scrollUpdate()}b=b||{};var c=this,d={speed:"speed"in b?b.speed:7};this.target=document.querySelector(a),this.animation={frame:new Date,stack:[]},this.identity="scroll"+parseInt(1e5*Math.random()),this.controls={place:null,scroll:null,height:0},this.speed=d.speed,this.target.style.overflow="hidden",this.draw(),requestAnimationFrame(f),this.target.onscroll=g,this.target.addEventListener("wheel",h),this.controls.place.onclick=i};MiniScroll.prototype.scrollUpdate=function(){this.controls.place.style.height=this.target.offsetHeight+"px";var a=this.countScrollHeight();this.controls.scroll.style.height=a.height,this.controls.scroll.style.top=a.top},MiniScroll.prototype.countScrollHeight=function(){for(var a=this.target.childNodes,b=parseInt(this.target.offsetHeight),c=0,d=0;d<a.length;d++)a[d].id!=this.identity&&(c+=parseInt(a[d].offsetHeight)||0);var e=this.target.offsetHeight*parseFloat(1/(parseFloat(c)/this.target.offsetHeight)),f=this.controls.place.offsetHeight*(this.target.scrollTop/c)+"px";return{mul:c/this.target.offsetHeight,height:e>b?b+"px":e+"px",top:f}},MiniScroll.prototype.draw=function(){var a=document.createElement("div"),b=document.createElement("div");a.className="scroll-place",b.className="scroll",a.appendChild(b),a.id=this.identity,this.controls.place=a,this.controls.scroll=b,this.target.insertBefore(a,this.target.querySelector("*")),this.scrollUpdate()},MiniScroll.prototype.render=function(a){for(var b=0;b<this.animation.stack.length;b++){var c=this.animation.stack[b],d=parseInt(c.target);c.element.style[c.prop]=d+c.points}};

And initialize:

<body onload="new MiniScroll(this);"></body>

And customize:

.scroll-place { // ... // }
.scroll { // ... // }

If you write an unmanaged program and use CreateProcess API then you should initialize lpStartupInfo parameter of the type STARTUPINFO so that wShowWindow field of the struct is SW_HIDE and not forget to use STARTF_USESHOWWINDOW flag in the dwFlags field of STARTUPINFO. Another method is to use CREATE_NO_WINDOW flag of dwCreationFlags parameter. The same trick work also with ShellExecute and ShellExecuteEx functions.

If you write a managed application you should follows advices from http://blogs.msdn.com/b/jmstall/archive/2006/09/28/createnowindow.aspx: initialize ProcessStartInfo with CreateNoWindow = true and UseShellExecute = false and then use as a parameter of . Exactly like in case of you can set property WindowStyle of ProcessStartInfo to ProcessWindowStyle.Hidden instead or together with CreateNoWindow = true.

You can use a VBS script which you start with wcsript.exe. Inside the script you can use CreateObject("WScript.Shell") and then Run with 0 as the second (intWindowStyle) parameter. See http://www.robvanderwoude.com/files/runnhide_vbs.txt as an example. I can continue with Kix, PowerShell and so on.

If you don't want to write any program you can use any existing utility like CMDOW /RUN /HID "c:\SomeDir\MyBatch.cmd", hstart /NOWINDOW /D=c:\scripts "c:\scripts\mybatch.bat", hstart /NOCONSOLE "batch_file_1.bat" which do exactly the same. I am sure that you will find much more such kind of free utilities.

In some scenario (for example starting from UNC path) it is important to set also a working directory to some local path (%SystemRoot%\system32 work always). This can be important for usage any from above listed variants of starting hidden batch.

This site has two pretty simple solutions - just check the code, I provided the descriptions in case you wanted them - saves you some clicks.

http://www.richardlord.net/blog/dates-in-php-and-mysql

1.One common solution is to store the dates in DATETIME fields and use PHPs date() and strtotime() functions to convert between PHP timestamps and MySQL DATETIMEs. The methods would be used as follows -

$mysqldate = date( 'Y-m-d H:i:s', $phpdate );
$phpdate = strtotime( $mysqldate );

2.Our second option is to let MySQL do the work. MySQL has functions we can use to convert the data at the point where we access the database. UNIX_TIMESTAMP will convert from DATETIME to PHP timestamp and FROM_UNIXTIME will convert from PHP timestamp to DATETIME. The methods are used within the SQL query. So we insert and update dates using queries like this -

$query = "UPDATE table SET
    datetimefield = FROM_UNIXTIME($phpdate)
    WHERE...";
$query = "SELECT UNIX_TIMESTAMP(datetimefield)
    FROM table WHERE...";

This works.

<html>
<head>
<script type = "text/javascript">
function write_below(form)
{
var input = document.forms.write.input_to_write.value;
document.getElementById('write_here').innerHTML="Your input was:"+input;
return false;
}
</script>
</head>

<!--Insert more code here-->
<body>
<form name='write' onsubmit='return write_below(this);'>
<input type = "text" name='input_to_write'>
<input type = "button" value = "submit" />
</form>
<div id='write_here'></div></body>
</html>

Returning false from the function never posts it to other page,but does edit the html content.

I had the same error in question, with the same issues as described by VSG24 in Proposed answer - nasty error message when typing 'dotnet' into CMD:

The program can't start because api-ms-win-crt-runtime-l1-1-0.dll is missing

I solved this by manually installing the following 2 updates on Windows Server 2012 R2 (and the pre-requisites and all the other updates linked - read the installation instructions carefully on the Microsoft website):

1. KB2919355
2. KB2999226

Hope this helps someone.

Single-dimensional arrays

For converting single-dimension arrays, you can cast using (array) or there's get_object_vars, which Benoit mentioned in his answer.

// Cast to an array
$array = (array) $object;

// get_object_vars
$array = get_object_vars($object);

They work slightly different from each other. For example, get_object_vars will return an array with only publicly accessible properties unless it is called from within the scope of the object you're passing (ie in a member function of the object). (array), on the other hand, will cast to an array with all public, private and protected members intact on the array, though all public now, of course.

Multi-dimensional arrays

A somewhat dirty method is to use PHP >= 5.2's native JSON functions to encode to JSON and then decode back to an array. This will not include private and protected members, however, and is not suitable for objects that contain data that cannot be JSON encoded (such as binary data).

// The second parameter of json_decode forces parsing into an associative array
$array = json_decode(json_encode($object), true);

Alternatively, the following function will convert from an object to an array including private and protected members, taken from here and modified to use casting:

function objectToArray ($object) {
    if(!is_object($object) && !is_array($object))
        return $object;

    return array_map('objectToArray', (array) $object);
}

I solved it in this way

A pkg-config file describes all necessary compile-time and link-time flags and dependencies needed to use a library.

pkg-config --static --libs glfw3

shows me that

-L/usr/local/lib -lglfw3 -lrt -lXrandr -lXinerama -lXi -lXcursor -lGL -lm -ldl -lXrender -ldrm -lXdamage -lX11-xcb -lxcb-glx -lxcb-dri2 -lxcb-dri3 -lxcb-present -lxcb-sync -lxshmfence -lXxf86vm -lXfixes -lXext -lX11 -lpthread -lxcb -lXau -lXdmcp  

I don't know if all these libs are actually necessary for compiling but for me it works...

Both Activity and Service actually extend Context so you can simply use this as your Context within your Service.

NotificationManager notificationManager =
    (NotificationManager) getSystemService(Service.NOTIFICATION_SERVICE);
Notification notification = new Notification(/* your notification */);
PendingIntent pendingIntent = /* your intent */;
notification.setLatestEventInfo(this, /* your content */, pendingIntent);
notificationManager.notify(/* id */, notification);

Make sure that the Key column's datatype is int and then setting identity manually, as image shows

Or just run this code

-- ID is the name of the  [to be] identity column
ALTER TABLE [yourTable] DROP COLUMN ID 
ALTER TABLE [yourTable] ADD ID INT IDENTITY(1,1)

the code will run, if ID is not the only column in the table

Thanks to David as his solution helped me come up with my solution for uploading multi-part files from my Heroku hosted site to S3 bucket. I did it using formidable to handle incoming form and fs to get the file content. Hopefully, it may help you.

api.service.ts

public upload(files): Observable<any> {  
    const formData: FormData = new FormData(); 
    files.forEach(file => {
      // create a new multipart-form for every file 
      formData.append('file', file, file.name);           
    });   
    return this.http.post(uploadUrl, formData).pipe(
      map(this.extractData),
      catchError(this.handleError)); 
  }
}

server.js

app.post('/api/upload', upload);
app.use('/api/upload', router);

upload.js

const IncomingForm = require('formidable').IncomingForm;
const fs = require('fs');
const AWS = require('aws-sdk');

module.exports = function upload(req, res) {
    var form = new IncomingForm();

    const bucket = new AWS.S3(
      {
        signatureVersion: 'v4',
        accessKeyId: process.env.AWS_ACCESS_KEY_ID,
        secretAccessKey: process.env.AWS_SECRET_ACCESS_KEY,
        region: 'us-east-1'       
      }
    ); 

    form.on('file', (field, file) => {

        const fileContent = fs.readFileSync(file.path);

        const s3Params = {
            Bucket: process.env.AWS_S3_BUCKET,
            Key: 'folder/' + file.name,
            Expires: 60,             
            Body: fileContent,
            ACL: 'public-read'
        };

        bucket.upload(s3Params, function(err, data) {
            if (err) {
                throw err;
            }            
            console.log('File uploaded to: ' + data.Location);
            fs.unlink(file.path, function (err) {
              if (err) {
                  console.error(err);
              }
              console.log('Temp File Delete');
          });
        });
    });              

    // The second callback is called when the form is completely parsed. 
    // In this case, we want to send back a success status code.
    form.on('end', () => {        
      res.status(200).json('upload ok');
    });

    form.parse(req);
}

What you're doing will work, and the browser will receive a 404 code. What it won't do is display the "not found" page that you might be expecting, e.g.:

Not Found

The requested URL /test.php was not found on this server.

That's because the web server doesn't send that page when PHP returns a 404 code (at least Apache doesn't). PHP is responsible for sending all its own output. So if you want a similar page, you'll have to send the HTML yourself, e.g.:

<?php
header($_SERVER["SERVER_PROTOCOL"]." 404 Not Found", true, 404);
include("notFound.php");
?>

You could configure Apache to use the same page for its own 404 messages, by putting this in httpd.conf:

ErrorDocument 404 /notFound.php

If your application often uses http protocol then REST is best because of its light weight, and knowing that your application uses only http protocol choosing SOAP is not so good because it heavy,Better to make decision on web service selection based on the protocols we use in our applications.

Simple solution

{{ orderTotal | number : '1.2-2'}}

//output like this

// public orderTotal = 220.45892221

//   {{ orderTotal | number : '1.2-2'}} 

// final Output
//  220.45

Signalling in Linux can be done with "kill" (man kill for the available signals), you'd need the process ID to do that. (ps ax | grep java) or something like that, or store the process id when the process gets created (this is used in most linux startup files, see /etc/init.d)

Portable signalling can be done by integrating a SocketServer in your java application. It's not that difficult and gives you the freedom to send any command you want.

If you meant finally clauses in stead of finalizers; they do not get extecuted when System.exit() is called. Finalizers should work, but shouldn't really do anything more significant but print a debug statement. They're dangerous.

Target= "_blank"

This does it in html, give it a try in C#

I had the same issue in 14.04, but I fixed it by these steps:

1. sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 7F0CEB10
2. echo "deb http://repo.mongodb.org/apt/ubuntu "$(lsb_release -sc)"/mongodb- org/3.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.0.list
3. sudo apt-get update
4. sudo apt-get install -y mongodb

It worked like charm :)

From @Jon Skeet comment, really the String value is "null". Following code solved it

if (userEmail != null && !userEmail.isEmpty() && !userEmail.equals("null")) 

navigateByUrl

routerLink directive as used like this:

<a [routerLink]="/inbox/33/messages/44">Open Message 44</a>

is just a wrapper around imperative navigation using router and its navigateByUrl method:

router.navigateByUrl('/inbox/33/messages/44')

as can be seen from the sources:

export class RouterLink {
  ...

  @HostListener('click')
  onClick(): boolean {
    ...
    this.router.navigateByUrl(this.urlTree, extras);
    return true;
  }

So wherever you need to navigate a user to another route, just inject the router and use navigateByUrl method:

class MyComponent {
   constructor(router: Router) {
      this.router.navigateByUrl(...);
   }
}

navigate

There's another method on the router that you can use - navigate:

router.navigate(['/inbox/33/messages/44'])

difference between the two

Using router.navigateByUrl is similar to changing the location bar directly–we are providing the “whole” new URL. Whereas router.navigate creates a new URL by applying an array of passed-in commands, a patch, to the current URL.

To see the difference clearly, imagine that the current URL is '/inbox/11/messages/22(popup:compose)'.

With this URL, calling router.navigateByUrl('/inbox/33/messages/44') will result in '/inbox/33/messages/44'. But calling it with router.navigate(['/inbox/33/messages/44']) will result in '/inbox/33/messages/44(popup:compose)'.

Read more in the official docs.

The site generates a unique token when it makes the form page. This token is required to post/get data back to the server.

Since the token is generated by your site and provided only when the page with the form is generated, some other site can't mimic your forms -- they won't have the token and therefore can't post to your site.

You could set the CommandTimeout property of the SQL Command to allow for the long running SQL transaction.

You might also need to look at the SQL Query that is causing the timeout.

Just happened to me when trying to send_keys to a search input box - that has autoupdate depending on what you type in. As mentioned by Eero, this can happen if your element does some Ajax updated while you are typing in your text inside the input element. The solution is to send one character at a time and search again for the input element. (Ex. in ruby shown below)

def send_keys_eachchar(webdriver, elem_locator, text_to_send)
  text_to_send.each_char do |char|
    input_elem = webdriver.find_element(elem_locator)
    input_elem.send_keys(char)
  end
end

The functions have different purposes. vector::insert allows you to insert an object at a specified position in the vector, whereas vector::push_back will just stick the object on the end. See the following example:

using namespace std;
vector<int> v = {1, 3, 4};
v.insert(next(begin(v)), 2);
v.push_back(5);
// v now contains {1, 2, 3, 4, 5}

You can use insert to perform the same job as push_back with v.insert(v.end(), value).

The docker run command has a --ulimit flag you can use this flag to set the open file limit in your docker container.

Run the following command when spinning up your container to set the open file limit.

docker run --ulimit nofile=<softlimit>:<hardlimit> the first value before the colon indicates the soft file limit and the value after the colon indicates the hard file limit. you can verify this by running your container in interactive mode and executing the following command in your containers shell ulimit -n

div p 

Selects all 'p' elements where the parent is a 'div' element

div > p

It means immediate children Selects all 'p' elements where the parent is a 'div' element

I solved this problem through the following:

1. In C # I built a String variable.

string userId="";

2. I put my list's item in this variable. I separated the ','.

for example: in C#

userId= "5,44,72,81,126";

and Send to SQL-Server

 SqlParameter param = cmd.Parameters.AddWithValue("@user_id_list",userId);

3. I Create Separated Function in SQL-server For Convert my Received List (that it's type is NVARCHAR(Max)) to Table.

CREATE FUNCTION dbo.SplitInts  
(  
   @List      VARCHAR(MAX),  
   @Delimiter VARCHAR(255)  
)  
RETURNS TABLE  
AS  
  RETURN ( SELECT Item = CONVERT(INT, Item) FROM  
      ( SELECT Item = x.i.value('(./text())[1]', 'varchar(max)')  
        FROM ( SELECT [XML] = CONVERT(XML, '<i>'  
        + REPLACE(@List, @Delimiter, '</i><i>') + '</i>').query('.')  
          ) AS a CROSS APPLY [XML].nodes('i') AS x(i) ) AS y  
      WHERE Item IS NOT NULL  
  );

4. In the main Store Procedure, using the command below, I use the entry list.

SELECT user_id = Item FROM dbo.SplitInts(@user_id_list, ',');

db.query(
        TABLE_NAME,
        new String[] { TABLE_ROW_ID, TABLE_ROW_ONE, TABLE_ROW_TWO },
        TABLE_ROW_ID + "=" + rowID,
        null, null, null, null, null
);

TABLE_ROW_ID + "=" + rowID, here = is the where clause. To select all values you will have to give all column names:

or you can use a raw query like this 
db.rawQuery("SELECT * FROM permissions_table WHERE name = 'Comics' ", null);

and here is a good tutorial for database.

When a chip gets power all of it's registers contain random values. It's not possible to have an an initial value. It will always be random.

This is why we have reset signals, to reset registers to a known value. The reset is controlled by something off chip, and we write our code to use it.

always @(posedge clk) begin
    if (reset == 1) begin // For an active high reset
        data_reg = 8'b10101011;
    end else begin
        data_reg = next_data_reg;
    end
end

onclick event to call a function

  <strike> <input type="button" value="NEXT"  onclick="document.write('<?php //call a function here ex- 'fun();' ?>');" />    </strike>

it will surely help you

it take a little more time than normal but wait it will work

Since phone numbers must conform to a pattern, you can use regular expressions to match the entered phone number against the pattern you define in regexp.

php has both ereg and preg_match() functions. I'd suggest using preg_match() as there's more documentation for this style of regex.

An example

$phone = '000-0000-0000';

if(preg_match("/^[0-9]{3}-[0-9]{4}-[0-9]{4}$/", $phone)) {
  // $phone is valid
}

application/force-download is not a standard MIME type. It's a hack supported by some browsers, added fairly recently.

Your question doesn't really make any sense. It's like asking why Internet Explorer 4 doesn't support the latest CSS 3 functionality.

Designated initializes will be supported in c++2a, but you don't have to wait, because they are officialy supported by GCC, Clang and MSVC.

#include <iostream>
#include <filesystem>

struct hello_world {
    const char* hello;
    const char* world;
};

int main () 
{
    hello_world hw = {
        .hello = "hello, ",
        .world = "world!"
    };
    
    std::cout << hw.hello << hw.world << std::endl;
    return 0;
}

Update 20201

As @Code Doggo noted, anyone who is using Visual Studio 2019 will need to set /std:c++latest  for the "C++ Language Standard" field contained under Configuration Properties -> C/C++ -> Language.

As of Notepad++ 6.9, the new Folder as Workspace feature can be used.

Folder as Workspace opens your folder(s) in a panel so you can browse folder(s) and open any file in Notepad++. Every changement in the folder(s) from outside will be synchronized in the panel. Usage: Simply drop 1 (or more) folder(s) in Notepad++.

This feature has the advantage of not showing your entire file system when just the working directory is needed. It also means you don't need plugins for it to work.

This one worked for me in the bash file.

git branch | grep '^*' | sed 's/* //'  


################bash file###################
#!/bin/bash
BRANCH=$(git branch | grep '^*' | sed 's/* //' )
echo $BRANCH

The environment variables displayed in Jenkins (Manage Jenkins -> System information) are inherited from the system (i.e. inherited environment variables)

If you run env command in a shell you should see the same environment variables as Jenkins shows.

These variables are either set by the shell/system or by you in ~/.bashrc, ~/.bash_profile.

There are also environment variables set by Jenkins when a job executes, but these are not displayed in the System Information.

If you're trying to just count how many of your cells in a range are not blank try this:

=COUNTA(range)

Example: (assume that it starts from A1 downwards):

---------    
Something 
---------
Something
---------

---------
Something
---------

---------
Something
---------

=COUNTA(A1:A6) returns 4 since there are two blank cells in there.

For Database first Aproach:

We can still set it in a constructor, by override the ContextName.Context.tt T4 Template this way:

<#=Accessibility.ForType(container)#> partial class <#=code.Escape(container)#> : DbContext
{
    public <#=code.Escape(container)#>()
        : base("name=<#=container.Name#>")
    {
        Database.CommandTimeout = 180;
<#
if (!loader.IsLazyLoadingEnabled(container))
{
#>
        this.Configuration.LazyLoadingEnabled = false;
<#
}

Database.CommandTimeout = 180; is the acutaly change.

The generated output is this:

public ContextName() : base("name=ContextName")
{
    Database.CommandTimeout = 180;
}

If you change your Database Model, this template stays, but the actualy class will be updated.

You can do it manually if you want.

preg_match('/windows|win32/i', $_SERVER['HTTP_USER_AGENT'])

preg_match('/iPhone|iPod|iPad/', $_SERVER['HTTP_USER_AGENT'])

You can even make it a script

$device = 'Blackberry'

preg_match("/$device/", $_SERVER['HTTP_USER_AGENT'])

Only this helped me:

To use the web administration gui you have to add the gui role :

<role rolename="admin"/>
<role rolename="admin-gui"/>
<role rolename="manager"/>
<role rolename="manager-gui"/>

<user username="name" password="pwd" roles="admin,admin-gui,manager,manager-gui"/>

You can log every query to a log file really easily:

mysql> SHOW VARIABLES LIKE "general_log%";

+------------------+----------------------------+
| Variable_name    | Value                      |
+------------------+----------------------------+
| general_log      | OFF                        |
| general_log_file | /var/run/mysqld/mysqld.log |
+------------------+----------------------------+

mysql> SET GLOBAL general_log = 'ON';

Do your queries (on any db). Grep or otherwise examine /var/run/mysqld/mysqld.log

Then don't forget to

mysql> SET GLOBAL general_log = 'OFF';

or the performance will plummet and your disk will fill!

In My case, it was just an extra StackPanel inside the ListView:

<ListView Name="_details" Margin="50,0,50,0">
            <StackPanel Orientation="Vertical">
                <StackPanel Orientation="Vertical">
                    <TextBlock Text="{Binding Location.LicenseName, StringFormat='Location: {0}'}"/>
                    <TextBlock Text="{Binding Ticket.Employee.s_name, StringFormat='Served by: {0}'}"/>
                    <TextBlock Text="{Binding Ticket.dt_create_time, StringFormat='Started at: {0}'}"/>
                    <Line StrokeThickness="2" Stroke="Gray" Stretch="Fill" Margin="0,5,0,5" />
                    <ItemsControl ItemsSource="{Binding Items}"/>
                </StackPanel>
            </StackPanel>
        </ListView>

Becomes:

<ListView Name="_details" Margin="50,0,50,0">
                <StackPanel Orientation="Vertical">
                    <TextBlock Text="{Binding Location.LicenseName, StringFormat='Location: {0}'}"/>
                    <TextBlock Text="{Binding Ticket.Employee.s_name, StringFormat='Served by: {0}'}"/>
                    <TextBlock Text="{Binding Ticket.dt_create_time, StringFormat='Started at: {0}'}"/>
                    <Line StrokeThickness="2" Stroke="Gray" Stretch="Fill" Margin="0,5,0,5" />
                    <ItemsControl ItemsSource="{Binding Items}"/>
                </StackPanel>
        </ListView>

and all is well.

The command (or the URL in it) to add the github repository as a remote isn't quite correct. If I understand your repository name correctly, it should be;

git remote add demo_app '[email protected]:levelone/demo_app.git'

Wget does not support multiple socket connections in order to speed up download of files.

I think we can do a bit better than gmarian answer.

The correct way is to use aria2.

aria2c -x 16 -s 16 [url]
#          |    |
#          |    |
#          |    |
#          ---------> the number of connections here

extension UIApplication {
    /// The top most view controller
    static var topMostViewController: UIViewController? {
        return UIApplication.shared.keyWindow?.rootViewController?.visibleViewController
    }
}

extension UIViewController {
    /// The visible view controller from a given view controller
    var visibleViewController: UIViewController? {
        if let navigationController = self as? UINavigationController {
            return navigationController.topViewController?.visibleViewController
        } else if let tabBarController = self as? UITabBarController {
            return tabBarController.selectedViewController?.visibleViewController
        } else if let presentedViewController = presentedViewController {
            return presentedViewController.visibleViewController
        } else {
            return self
        }
    }
}

With this you can easily present your alert like so

UIApplication.topMostViewController?.present(viewController, animated: true, completion: nil)

One thing to note is that if there's a UIAlertController currently being displayed, UIApplication.topMostViewController will return a UIAlertController. Presenting on top of a UIAlertController has weird behavior and should be avoided. As such, you should either manually check that !(UIApplication.topMostViewController is UIAlertController) before presenting, or add an else if case to return nil if self is UIAlertController

extension UIViewController {
    /// The visible view controller from a given view controller
    var visibleViewController: UIViewController? {
        if let navigationController = self as? UINavigationController {
            return navigationController.topViewController?.visibleViewController
        } else if let tabBarController = self as? UITabBarController {
            return tabBarController.selectedViewController?.visibleViewController
        } else if let presentedViewController = presentedViewController {
            return presentedViewController.visibleViewController
        } else if self is UIAlertController {
            return nil
        } else {
            return self
        }
    }
}

You can also use vavr:

import io.vavr.collection.HashSet;

HashSet.of("a", "b").toJavaSet();

That's because you defined your own version of name for your enum, and getByName doesn't use that.

getByName("COLUMN_HEADINGS") would probably work.

Try using unbindService() in OnUserLeaveHint(). It prevents the the ServiceConnection leaked scenario and other exceptions.
I used it in my code and works fine.

While searching this very question I discovered this example in the documentation.

QPushButton *quitButton = new QPushButton("Quit");
connect(quitButton, &QPushButton::clicked, &app, &QCoreApplication::quit, Qt::QueuedConnection);

Mutatis mutandis for your particular action of course.

Along with this note.

It's good practice to always connect signals to this slot using a QueuedConnection. If a signal connected (non-queued) to this slot is emitted before control enters the main event loop (such as before "int main" calls exec()), the slot has no effect and the application never exits. Using a queued connection ensures that the slot will not be invoked until after control enters the main event loop.

It's common to connect the QGuiApplication::lastWindowClosed() signal to quit()

With JSON.stringify() found in json2.js or native in most modern browsers.

   JSON.stringify(value, replacer, space)
        value       any JavaScript value, usually an object or array.

       replacer    an optional parameter that determines how object
                    values are stringified for objects. It can be a
                    function or an array of strings.

       space       an optional parameter that specifies the indentation
                    of nested structures. If it is omitted, the text will
                    be packed without extra whitespace. If it is a number,
                    it will specify the number of spaces to indent at each
                    level. If it is a string (such as '\t' or ' '),
                    it contains the characters used to indent at each level.

       This method produces a JSON text from a JavaScript value.

In your Activity.java import android.support.v7.widget.Toolbar instead of android.widget.Toolbar:

import android.app.ActionBar;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.support.v7.widget.Toolbar;


public class rutaActivity extends AppCompactActivity {

private Toolbar toolbar;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_ruta);

    getSupportActionBar().hide();//Ocultar ActivityBar anterior

    toolbar = (Toolbar) findViewById(R.id.app_bar);
    setSupportActionBar(toolbar); //NO PROBLEM !!!!

Update:

If you are using androidx, replace

import android.support.v7.widget.Toolbar;
import android.support.v7.app.AppCompatActivity;

with newer imports

import androidx.appcompat.widget.Toolbar;
import androidx.appcompat.app.AppCompatActivity;

Swift 3 solution based on Ramis' answer:

extension String {
    func withReplacedCharacters(_ characters: String, by separator: String) -> String {
        let characterSet = CharacterSet(charactersIn: characters)
        return components(separatedBy: characterSet).joined(separator: separator)
    }
}

Tried to come up with an appropriate function name according to Swift 3 naming convention.

For the answer to your first question refer to this answer - https://stackoverflow.com/a/65447848/4691279

For your second question - you can use command like docker ps --filter "name=<<<YOUR_CONTAINER_NAME>>>" to check whether a particular container is running or not.

• If Docker and Container both are running then you will get output like below:

  $ docker ps --filter "name=nostalgic_stallman"
  
  CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES       
  9b6247364a03        busybox             "top"               2 minutes ago       Up 2 minutes                            nostalgic_stallman
  

• If Docker is not running then you will get an error message saying docker daemon is not running.

• If Docker running but Container is not running then you will not get the container name in the output of this command.

The closest equivalent to your VB would be (see this):

Convert.IsDBNull()

If the fallback keys are not too many you can do something like this

value = my_dict.get('first_key') or my_dict.get('second_key')

Project Properties -> Signing -> uncheck "Sign the ClickOnce Manifest"

Also as this MS article suggests,

If you are using Visual Studio 2008 and are targeting .NET 3.5 and using automatic updates, you can just change the certificate and deploy a new version,

This is a problem with your remote. When you do git push origin master, origin is the remote and master is the branch you're pushing.

When you do this:

git remote

I bet the list does not include origin. To re-add the origin remote:

git remote add origin [email protected]:your_github_username/your_github_app.git

Or, if it exists but is formatted incorrectly:

git remote rm origin
git remote add origin [email protected]:your_github_username/your_github_app.git

A workaround tested on Windows(cmd.exe), Linux(Bash and zsh) and OS X(zsh):

#include <stdlib.h>

void clrscr()
{
    system("@cls||clear");
}

By default Mysql store and return ‘date’ data type values in “YYYY/MM/DD” format. So if we want to display date in different format then we have to format date values as per our requirement in scripting language

And by the way what is the column data type and in which format you are storing the value.

I have implemented another solution to the problem, I found it more efficient in counting rows:

try
(
   FileReader       input = new FileReader("input.txt");
   LineNumberReader count = new LineNumberReader(input);
)
{
   while (count.skip(Long.MAX_VALUE) > 0)
   {
      // Loop just in case the file is > Long.MAX_VALUE or skip() decides to not read the entire file
   }

   result = count.getLineNumber() + 1;                                    // +1 because line index starts at 0
}

You will have to split this into multiple statements. Here is one way to do that:

if (!obj.isPresent()) {
  logger.fatal("Object not available");
}

obj.ifPresent(o -> o.setAvailable(true));
return obj;

Another way (possibly over-engineered) is to use map:

if (!obj.isPresent()) {
  logger.fatal("Object not available");
}

return obj.map(o -> {o.setAvailable(true); return o;});

If obj.setAvailable conveniently returns obj, then you can simply the second example to:

if (!obj.isPresent()) {
  logger.fatal("Object not available");
}

return obj.map(o -> o.setAvailable(true));

You cannot capture loopback on Solaris, HP-UX, or Windows, however you can very easily work around this limitation by using a tool like RawCap.

RawCap can capture raw packets on any ip including 127.0.0.1 (localhost/loopback). Rawcap can also generate a pcap file. You can open and analyze the pcap file with Wireshark.

See here for full details on how to monitor localhost using RawCap and Wireshark.

On Android 4.4.4, it seems the only way I could stop an alpha fading animation on a View was calling View.animate().cancel() (i.e., calling .cancel() on the View's ViewPropertyAnimator).

Here's the code I'm using for compatibility before and after ICS:

public void stopAnimation(View v) {
    v.clearAnimation();
    if (canCancelAnimation()) {
        v.animate().cancel();
    }
}

... with the method:

/**
 * Returns true if the API level supports canceling existing animations via the
 * ViewPropertyAnimator, and false if it does not
 * @return true if the API level supports canceling existing animations via the
 * ViewPropertyAnimator, and false if it does not
 */
public static boolean canCancelAnimation() {
    return Build.VERSION.SDK_INT >= Build.VERSION_CODES.ICE_CREAM_SANDWICH;
}

Here's the animation that I'm stopping:

v.setAlpha(0f);
v.setVisibility(View.VISIBLE);
// Animate the content view to 100% opacity, and clear any animation listener set on the view.
v.animate()
    .alpha(1f)
    .setDuration(animationDuration)
    .setListener(null);

If you want to use the cd or ls functions , you need proper identifiers before the function names ( % and ! respectively) use %cd and !ls to navigate

.

!ls    # to find the directory you're in ,
%cd ./samplefolder  #if you wanna go into a folder (say samplefolder)

or if you wanna go out of the current folder

%cd ../      

and then navigate to the required folder/file accordingly

The way I understand it is also, there should be a third term added to the mix: Task.

Async is just a qualifier you put on your method to say it's an asynchronous method.

Task is the return of the async function. It executes asynchronously.

You await a Task. When code execution reaches this line, control jumps out back to caller of your surrounding original function.

If instead, you assign the return of an async function (ie Task) to a variable, when code execution reaches this line, it just continues past that line in the surrounding function while the Task executes asynchronously.

A regex is good for matching the general format but I think you should move parsing to the Date class, e.g.:

function parseDate(str) {
  var m = str.match(/^(\d{1,2})\/(\d{1,2})\/(\d{4})$/);
  return (m) ? new Date(m[3], m[2]-1, m[1]) : null;
}

Now you can use this function to check for valid dates; however, if you need to actually validate without rolling (e.g. "31/2/2010" doesn't automatically roll to "3/3/2010") then you've got another problem.

[Edit] If you also want to validate without rolling then you could add a check to compare against the original string to make sure it is the same date:

function parseDate(str) {
  var m = str.match(/^(\d{1,2})\/(\d{1,2})\/(\d{4})$/)
    , d = (m) ? new Date(m[3], m[2]-1, m[1]) : null
    , nonRolling = (d&&(str==[d.getDate(),d.getMonth()+1,d.getFullYear()].join('/')));
  return (nonRolling) ? d : null;
}

[Edit2] If you want to match against zero-padded dates (e.g. "08/08/2013") then you could do something like this:

function parseDate(str) {
  function pad(x){return (((''+x).length==2) ? '' : '0') + x; }
  var m = str.match(/^(\d{1,2})\/(\d{1,2})\/(\d{4})$/)
    , d = (m) ? new Date(m[3], m[2]-1, m[1]) : null
    , matchesPadded = (d&&(str==[pad(d.getDate()),pad(d.getMonth()+1),d.getFullYear()].join('/')))
    , matchesNonPadded = (d&&(str==[d.getDate(),d.getMonth()+1,d.getFullYear()].join('/')));
  return (matchesPadded || matchesNonPadded) ? d : null;
}

However, it will still fail for inconsistently padded dates (e.g. "8/08/2013").

IN objective-c, if you are dealing with regular char arrays (instead of pointers to NSString) you could also use:

printf("%.02f", your_float_var);

OTOH, if what you want is to store that value on a char array you could use:

sprintf(your_char_ptr, "%.02f", your_float_var);

Yes. Have a look at Wikipedia and Cloanto Implementation of INI File Format (see bottom of page).

Interlocked functions do not lock. They are atomic, meaning that they can complete without the possibility of a context switch during increment. So there is no chance of deadlock or wait.

I would say that you should always prefer it to a lock and increment.

Volatile is useful if you need writes in one thread to be read in another, and if you want the optimizer to not reorder operations on a variable (because things are happening in another thread that the optimizer doesn't know about). It's an orthogonal choice to how you increment.

This is a really good article if you want to read more about lock-free code, and the right way to approach writing it

Did you play around with setDefaultUncaughtExceptionHandler() and the alike methods of the Thread class? From the API: "By setting the default uncaught exception handler, an application can change the way in which uncaught exceptions are handled (such as logging to a specific device, or file) for those threads that would already accept whatever "default" behavior the system provided."

You might find the answer to your problem there... good luck! :-)

I cam up with a recursive solution:

def sumDigits(num):
#   print "evaluating:", num
  if num < 10:
    return num

  # solution 1
#   res = num/10
#   rem = num%10
#   print "res:", res, "rem:", rem
#   return sumDigits(res+rem)

    # solution 2
  arr = [int(i) for i in str(num)]
  return sumDigits(sum(arr))

# print(sumDigits(1))
# print(sumDigits(49))
print(sumDigits(439230))
# print(sumDigits(439237))

I wrote this extension method based off @Lee's response to the OP. Note, a default parameter was used (requiring C# 4.0). However, an overloaded method call in C# 3.0 would suffice.

/// <summary>
/// Method that returns all the duplicates (distinct) in the collection.
/// </summary>
/// <typeparam name="T">The type of the collection.</typeparam>
/// <param name="source">The source collection to detect for duplicates</param>
/// <param name="distinct">Specify <b>true</b> to only return distinct elements.</param>
/// <returns>A distinct list of duplicates found in the source collection.</returns>
/// <remarks>This is an extension method to IEnumerable&lt;T&gt;</remarks>
public static IEnumerable<T> Duplicates<T>
         (this IEnumerable<T> source, bool distinct = true)
{
     if (source == null)
     {
        throw new ArgumentNullException("source");
     }

     // select the elements that are repeated
     IEnumerable<T> result = source.GroupBy(a => a).SelectMany(a => a.Skip(1));

     // distinct?
     if (distinct == true)
     {
        // deferred execution helps us here
        result = result.Distinct();
     }

     return result;
}

If you are using maven, adding below dependency should work

<dependency>
    <groupId>javax.persistence</groupId>
    <artifactId>persistence-api</artifactId>
    <version>1.0</version>
</dependency>

The simplest is to convert to a set then back to a list:

my_list = list(set(my_list))

One disadvantage with this is that it won't preserve the order. You may also want to consider if a set would be a better data structure to use in the first place, instead of a list.

You need to change the sshd_config file in the remote server (probably in /etc/ssh/sshd_config).

Change

PasswordAuthentication no

to

PasswordAuthentication yes

And then restart the sshd daemon.

If you are working with Asp.net core and using appsettings.json than write server as localhost and after write sql instance name for enabled named pipe like this

  "ConnectionString": {
    "dewDB": "server=localhost\\dewelopersql;database=dewdb;User ID=sa;password=XXXXX",
  },

you can use addView or removeView

java:

// Root Layout
LinearLayout linearLayout = new LinearLayout(context);
linearLayout.setGravity(Gravity.CENTER);
linearLayout.setOrientation(LinearLayout.VERTICAL);

// TextView
TextView textView = new TextView(context);
textView.setText("Sample");

// Add TextView in LinearLayout
linearLayout.addView(textView);

// Remove TextView from LinearLayout
linearLayout.removeView(textView);

kotlin:

// Root Layout
val linearLayout = LinearLayout(context)
linearLayout.gravity = Gravity.CENTER
linearLayout.orientation = LinearLayout.VERTICAL

// TextView
val textView = TextView(context)
textView.text = "Sample"

// Add TextView in LinearLayout
linearLayout.addView(textView)

// Remove TextView from LinearLayout
linearLayout.removeView(textView)

Create 2 methods which handle the cases. You can instruct the @RequestMapping annotation to take into account certain parameters whilst mapping the request. That way you can nicely split this into 2 methods.

@RequestMapping (value="/submit/id/{id}", method=RequestMethod.GET, 
                 produces="text/xml", params={"logout"})
public String handleLogout(@PathVariable("id") String id, 
        @RequestParam("logout") String logout) { ... }

@RequestMapping (value="/submit/id/{id}", method=RequestMethod.GET, 
                 produces="text/xml", params={"name", "password"})
public String handleLogin(@PathVariable("id") String id, @RequestParam("name") 
        String username, @RequestParam("password") String password, 
        @ModelAttribute("submitModel") SubmitModel model, BindingResult errors) 
        throws LoginException {...}

Your problem is here:

2013-11-14 17:57:20 5180 [ERROR] InnoDB: .\ibdata1 can't be opened in read-write mode

There's some problem with the ibdata1 file - maybe the permissions have changed on it? Perhaps some other process has it open. Does it even exist?

Fix this and possibly everything else will fall into place.

The result is same for all options. Redirect.

<meta> in HTML:

• Show content of your site, and next redirect user after a few (or 0) seconds.
• Don't need JavaScript enabled.
• Don't need PHP.

window.location in JS:

• Javascript enabled needed.
• Don't need PHP.
• Show content of your site, and next redirect user after a few (or 0) seconds.
• Redirect can be dependent on any conditions if (1 === 1) { window.location.href = 'http://example.com'; }.

header('Location:') in PHP:

• Don't need JavaScript enabled.
• PHP needed.
• Redirect will be executed first, user never see what is after. header() must be the first command in php script, before output any other. If you try output some before header, will receive an Warning: Cannot modify header information - headers already sent

There is a simple and elegant way to do this. If you are passing the user_id in a body request or through a query parameter. e.g

/update/profile?user_id=

Then in your request rules

  public function rules(Request $request)
    {
        return [
            'first_name' => 'required|string',
            'last_name' => 'required|string',
            'email' => ['required','email', 'string', Rule::unique('users')->ignore($request->user_id )],
            'phone_number' => ['required', 'string', Rule::unique('users')->ignore($request->user_id )],
        ];
    }

Better Still, you can pass in auth->id() in place of $request->user_id to get the login user id.

You can use top or ps commands to check the CPU usage.

using top : This will show you the cpu stats

top -b -n 1 |grep ^Cpu

using ps: This will show you the % cpu usage for each process.

ps -eo pcpu,pid,user,args | sort -r -k1 | less

Also, you can write a small script in bash or perl to read /proc/stat and calculate the CPU usage.

I like Ibu's one but, I think I have a better solution using his idea.

//Fade In.
element.style.opacity = 0;
var Op1 = 0;
var Op2 = 1;
var foo1, foo2;
foo1 = setInterval(Timer1, 20);
function Timer1()
{
    element.style.opacity = Op1;
    Op1 = Op1 + .01;
    console.log(Op1); //Option, but I recommend it for testing purposes.
    if (Op1 > 1)
    {
        clearInterval(foo1);
        foo2 = setInterval(Timer3, 20);
    }
}

This solution uses a additional equation unlike Ibu's solution, which used a multiplicative equation. The way it works is it takes a time increment (t), an opacity increment (o), and a opacity limit (l) in the equation, which is: (T = time of fade in miliseconds) [T = (l/o)*t]. the "20" represents the time increments or intervals (t), the ".01" represents the opacity increments (o), and the 1 represents the opacity limit (l). When you plug the numbers in the equation you get 2000 milliseconds (or 2 seconds). Here is the console log:

Notice how the opacity follows the opacity increment amount of .01 just like in the code. If you use the code Ibu made,

//I made slight edits but keeped the ESSENTIAL stuff in it.
var op = 0.01;  // initial opacity
var timer = setInterval(function () {
    if (op >= 1){
        clearInterval(timer);
    }
    element.style.opacity = op;
    op += op * 0.1;
}, 20);

you will get these numbers (or something similar) in you console log. Here is what I got.

Notice that there is no discernible pattern. If you ran Ibu's code, you would never know how long the fade was. You would have to grab a timer and guess and check 2 seconds. Nonetheless, Ibu's code did make a pretty nice fade in (it probably works for fade out. I don't know because I didn't use a fade out yet). My code will also work for a fade out. Let's just say you wanted 2 seconds for a fade out. You can do that with my code. Here is how it would look:

//Fade out. (Continued from the fade in.
function Timer2()
{
    element.style.opacity = Op2;
    Op2 = Op2 - .01;
    console.log(Op2); //Option, but I recommend it for testing purposes.
    if (Op2 < 0)
    { 
        clearInterval(foo2);
    }
}

All I did was change the opacity to 1 (or fully opaque). I changed the opacity increment to -.01 so it would start turning invisible. Lastly, I changed the opacity limit to 0. When it hits the opacity limit, the timer will stop. Same as the last one, except it used 1 instead of 0. When you run the code, here is what the console log should relatively look like.

As you can see, the .01 pattern still exists in the fade out. Both fades are smooth and precise. I hope these codes helped you or gave you insight on the topic. If you have any additions or suggestions let me know. Thank you for taking the time to view this!

The best answer

sheet.addMergedRegion(new CellRangeAddress(start-col,end-col,start-cell,end-cell));

This code not only allows you to add two columns, it allows you to add as many coloumns as you want and align them left or right, change colors, add links etc. Check out the Fiddle link also

From FOR /? help doc:

FOR %variable IN (set) DO command [command-parameters]

%variable Specifies a single letter replaceable parameter.
(set) Specifies a set of one or more files. Wildcards may be used. command Specifies the command to carry out for each file.
command-parameters
Specifies parameters or switches for the specified command.

To use the FOR command in a batch program, specify %%variable instead
of %variable. Variable names are case sensitive, so %i is different
from %I.

If Command Extensions are enabled, the following additional
forms of the FOR command are supported:

FOR /D %variable IN (set) DO command [command-parameters]

If set contains wildcards, then specifies to match against directory  
names instead of file names.                                          

FOR /R [[drive:]path] %variable IN (set) DO command [command-parameters]

Walks the directory tree rooted at [drive:]path, executing the FOR    
statement in each directory of the tree.  If no directory             
specification is specified after /R then the current directory is     
assumed.  If set is just a single period (.) character then it        
will just enumerate the directory tree.                               

FOR /L %variable IN (start,step,end) DO command [command-parameters]

The set is a sequence of numbers from start to end, by step amount.   
So (1,1,5) would generate the sequence 1 2 3 4 5 and (5,-1,1) would   
generate the sequence (5 4 3 2 1)                                     

<script type="text/javascript">
  top.frames['DetailFrame'].location = top.frames['DetailFrame'].location;
</script> 

elementwise compare ? what about

public void Linq78a()
{
 int[] numbers1 = { 5, 4, 1, 3, 9, 8, 6, 7, 2, 0 };
 int[] numbers = { 5, 4, 1, 3, 9, 8, 6, 7, 2, 0 };
 bool bb = numbers.Zip(numbers1, (a, b) => (a == b)).Any(p => !p);
 if (!bb) Console.WriteLine("Lists are equal (bb)");
   else Console.WriteLine("Lists are not equal (bb)");
}

Replace the (a==b) condition by anything you'd like to compare in a and b.

(this combines two examples from MSDN developer Linq samples)

It's not possible to do it just like that, but you can overlay an opaque div between the div with the background-image and the text and fade that one out, hence giving the appearance that the background is fading in.

You can introduce another variable. It doesnt consolidate both checks, but it at least avoids having to put the body in twice:

do_it = 
ifeq ($(GCC_MINOR), 4)
    do_it = yes
endif
ifeq ($(GCC_MINOR), 5)
    do_it = yes
endif
ifdef do_it
    CFLAGS += -fno-strict-overflow
endif

this will provide exact output

import csv

import collections

with open('file.csv', 'rb') as f:

  data = list(csv.reader(f))

counter = collections.defaultdict(int)

for row in data:

    counter[row[0]] += 1

writer = csv.writer(open("file1.csv", 'w'))

for row in data:

    if counter[row[0]] >= 1:

        writer.writerow(row)

You have too many methods. There can only be 65536 methods for dex.

As suggested you can use the multidex support.

Just add these lines in the module/build.gradle:

android {

    defaultConfig {
        ...

        // Enabling multidex support.
        multiDexEnabled true
    }
    ...
}

dependencies {
  implementation 'com.android.support:multidex:1.0.3'  //with support libraries
  //implementation 'androidx.multidex:multidex:2.0.1'  //with androidx libraries
}

Also in your Manifest add the MultiDexApplication class from the multidex support library to the application element

    <?xml version="1.0" encoding="utf-8"?>
    <manifest xmlns:android="http://schemas.android.com/apk/res/android"
        package="com.example.android.multidex.myapplication">
        <application
            ...
            android:name="android.support.multidex.MultiDexApplication">

            <!-- If you are using androidx use android:name="androidx.multidex.MultiDexApplication" -->

            <!--If you are using your own custom Application class then extend -->
            <!--MultiDexApplication and change above line as-->
            <!--android:name=".YourCustomApplicationClass"> -->

            ...
        </application>
    </manifest>

If you are using your own Application class, change the parent class from Application to MultiDexApplication.
If you can't do it, in your Application class override the attachBaseContext method with:

@Override
protected void attachBaseContext(Context newBase) {
    super.attachBaseContext(newBase);
    MultiDex.install(this);
}

Another solution is to try to remove unused code with ProGuard - Configure the ProGuard settings for your app to run ProGuard and ensure you have shrinking enabled for release builds.

Note that there are things that happen between the calls to onStart() and onResume(). Namely, onNewIntent(), which I've painfully found out.

If you are using the SINGLE_TOP flag, and you send some data to your activity, using intent extras, you will be able to access it only in onNewIntent(), which is called after onStart() and before onResume(). So usually, you will take the new (maybe only modified) data from the extras and set it to some class members, or use setIntent() to set the new intent as the original activity intent and process the data in onResume().

In order to increase or decrease time using strtotime you could use a Relative format in the first argument.

In your case to increase the current time by 10 hours:

$date = date('h:i:s A', strtotime('+10 hours'));

In case you need to apply the change to another timestamp, the second argument can be specified.

Note:

Using this function for mathematical operations is not advisable. It is better to use DateTime::add() and DateTime::sub() in PHP 5.3 and later, or DateTime::modify() in PHP 5.2.

So, the recommended way since PHP 5.3:

$dt = new DateTime(); // assuming we need to add to the current time
$dt->add(new DateInterval('PT10H'));
$date = $dt->format('h:i:s A');

or using aliases:

$dt = date_create(); // assuming we need to add to the current time
date_add($dt, date_interval_create_from_date_string('10 hours')); 
$date = date_format($dt, 'h:i:s A');

In all cases the default time zone will be used unless a time zone is specified.

$anchorScroll is indeed the answer to this, but there's a much better way to use it in more recent versions of Angular.

Now, $anchorScroll accepts the hash as an optional argument, so you don't have to change $location.hash at all. (documentation)

This is the best solution because it doesn't affect the route at all. I couldn't get any of the other solutions to work because I'm using ngRoute and the route would reload as soon as I set $location.hash(id), before $anchorScroll could do its magic.

Here is how to use it... first, in the directive or controller:

$scope.scrollTo = function (id) {
  $anchorScroll(id);  
}

and then in the view:

<a href="" ng-click="scrollTo(id)">Text</a>

Also, if you need to account for a fixed navbar (or other UI), you can set the offset for $anchorScroll like this (in the main module's run function):

  .run(function ($anchorScroll) {
      //this will make anchorScroll scroll to the div minus 50px
      $anchorScroll.yOffset = 50;
  });

    private static DataTable ReadFTP_CSV()
    {
        String ftpserver = "ftp://servername/ImportData/xxxx.csv";
        FtpWebRequest reqFTP = (FtpWebRequest)FtpWebRequest.Create(new Uri(ftpserver));

        reqFTP.Credentials = new NetworkCredential(ftpUserID, ftpPassword);
        FtpWebResponse response = (FtpWebResponse)reqFTP.GetResponse();

        Stream responseStream = response.GetResponseStream();

        // use the stream to read file from FTP 
        StreamReader sr = new StreamReader(responseStream);
        DataTable dt_csvFile = new DataTable();

        #region Code
        //Add Code Here To Loop txt or CSV file
        #endregion

        return dt_csvFile;

    }

I hope it can help you.

Put the loops in a subroutine and call return

Just in case it helps someone, here's what caused this error for me: I needed a procedure to return json but I left out the for json path:

set @jsonout = (SELECT ID, SumLev, Census_GEOID, AreaName, Worksite 
            from CS_GEO G (nolock) 
                join @allids a on g.ID = a.[value] 
            where g.Worksite = @worksite)

When I tried to save the stored procedure, it threw the error. I fixed it by adding for json path to the code at the end of the procedure:

set @jsonout = (SELECT ID, SumLev, Census_GEOID, AreaName, Worksite 
            from CS_GEO G (nolock) 
                join @allids a on g.ID = a.[value] 
            where g.Worksite = @worksite for json path)

var example = "I am too long string";
var result;

// Slice is JS function
result = example.slice(0, 10)+'...'; //if you need dots after the string you can add

Result variable contains "I am too l..."

Use LinqToObject : contacts.AsEnumerable()

var items = from c in contacts.AsEnumerable()
            select new ListItem
            {
                Value = c.ContactId.ToString(),
                Text = c.Name
            };

Here's the answer I found:

Just to make the definition complete, in the Cartesian coordinate system:

• the x-axis goes through long,lat (0,0), so longitude 0 meets the equator;
• the y-axis goes through (0,90);
• and the z-axis goes through the poles.

The conversion is:

x = R * cos(lat) * cos(lon)

y = R * cos(lat) * sin(lon)

z = R *sin(lat)

Where R is the approximate radius of earth (e.g. 6371 km).

If your trigonometric functions expect radians (which they probably do), you will need to convert your longitude and latitude to radians first. You obviously need a decimal representation, not degrees\minutes\seconds (see e.g. here about conversion).

The formula for back conversion:

   lat = asin(z / R)
   lon = atan2(y, x)

asin is of course arc sine. read about atan2 in wikipedia. Don’t forget to convert back from radians to degrees.

This page gives c# code for this (note that it is very different from the formulas), and also some explanation and nice diagram of why this is correct,

If you don't want to create a new dataframe, or if your dataframe has more columns than just the ones you want to split, you could:

df["flips"], df["row_name"] = zip(*df["row"].str.split().tolist())
del df["row"]
