Why not use an empty ajax update panel and wire the linkbutton's click event to it? This way only the update panel will get updated, thus avoiding a postback and allowing you to run your javascript

The easiest way would be to use a GUI:

For Gnome use gnome-schedule (universe)

sudo apt-get install gnome-schedule 

For KDE use kde-config-cron

It should be pre installed on Kubuntu

But if you use a headless linux or don´t want GUI´s you may use:

crontab -e

If you type it into Terminal you´ll get a table.
You have to insert your cronjobs now.
Format a job like this:

*     *     *     *     *  YOURCOMMAND
-     -     -     -     -
|     |     |     |     |
|     |     |     |     +----- Day in Week (0 to 7) (Sunday is 0 and 7)
|     |     |     +------- Month (1 to 12)
|     |     +--------- Day in Month (1 to 31)
|     +----------- Hour (0 to 23)
+------------- Minute (0 to 59)

There are some shorts, too (if you don´t want the *):

@reboot --> only once at startup
@daily ---> once a day
@midnight --> once a day at midnight
@hourly --> once a hour
@weekly --> once a week
@monthly --> once a month
@annually --> once a year
@yearly --> once a year

If you want to use the shorts as cron (because they don´t work or so):

@daily --> 0 0 * * *
@midnight --> 0 0 * * *
@hourly --> 0 * * * *
@weekly --> 0 0 * * 0
@monthly --> 0 0 1 * *
@annually --> 0 0 1 1 *
@yearly --> 0 0 1 1 *

The best way in browsers that support it, is to send the file as a Blob, or using FormData if you want a multipart form. You do not need a FileReader for that. This is both simpler and more efficient than trying to read the data.

If you specifically want to send it as multipart/form-data, you can use a FormData object:

var xmlHttpRequest = new XMLHttpRequest();
xmlHttpRequest.open("POST", '/pushfile', true);
var formData = new FormData();
// This should automatically set the file name and type.
formData.append("file", file);
// Sending FormData automatically sets the Content-Type header to multipart/form-data
xmlHttpRequest.send(formData);

You can also send the data directly, instead of using multipart/form-data. See the documentation. Of course, this will need a server-side change as well.

// file is an instance of File, e.g. from a file input.
var xmlHttpRequest = new XMLHttpRequest();
xmlHttpRequest.open("POST", '/pushfile', true);

xmlHttpRequest.setRequestHeader("Content-Type", file.type);

// Send the binary data.
// Since a File is a Blob, we can send it directly.
xmlHttpRequest.send(file);

For browser support, see: http://caniuse.com/#feat=xhr2 (most browsers, including IE 10+).

The message means that both the packages have functions with the same names. In this particular case, the testthat and assertive packages contain five functions with the same name.

When two functions have the same name, which one gets called?

R will look through the search path to find functions, and will use the first one that it finds.

search()
 ##  [1] ".GlobalEnv"        "package:assertive" "package:testthat" 
 ##  [4] "tools:rstudio"     "package:stats"     "package:graphics" 
 ##  [7] "package:grDevices" "package:utils"     "package:datasets" 
 ## [10] "package:methods"   "Autoloads"         "package:base"

In this case, since assertive was loaded after testthat, it appears earlier in the search path, so the functions in that package will be used.

is_true
## function (x, .xname = get_name_in_parent(x)) 
## {
##     x <- coerce_to(x, "logical", .xname)
##     call_and_name(function(x) {
##         ok <- x & !is.na(x)
##         set_cause(ok, ifelse(is.na(x), "missing", "false"))
##     }, x)
## }
<bytecode: 0x0000000004fc9f10>
<environment: namespace:assertive.base>

The functions in testthat are not accessible in the usual way; that is, they have been masked.

What if I want to use one of the masked functions?

You can explicitly provide a package name when you call a function, using the double colon operator, ::. For example:

testthat::is_true
## function () 
## {
##     function(x) expect_true(x)
## }
## <environment: namespace:testthat>

How do I suppress the message?

If you know about the function name clash, and don't want to see it again, you can suppress the message by passing warn.conflicts = FALSE to library.

library(testthat)
library(assertive, warn.conflicts = FALSE)
# No output this time

Alternatively, suppress the message with suppressPackageStartupMessages:

library(testthat)
suppressPackageStartupMessages(library(assertive))
# Also no output

Impact of R's Startup Procedures on Function Masking

If you have altered some of R's startup configuration options (see ?Startup) you may experience different function masking behavior than you might expect. The precise order that things happen as laid out in ?Startup should solve most mysteries.

For example, the documentation there says:

Note that when the site and user profile files are sourced only the base package is loaded, so objects in other packages need to be referred to by e.g. utils::dump.frames or after explicitly loading the package concerned.

Which implies that when 3rd party packages are loaded via files like .Rprofile you may see functions from those packages masked by those in default packages like stats, rather than the reverse, if you loaded the 3rd party package after R's startup procedure is complete.

How do I list all the masked functions?

First, get a character vector of all the environments on the search path. For convenience, we'll name each element of this vector with its own value.

library(dplyr)
envs <- search() %>% setNames(., .)

For each environment, get the exported functions (and other variables).

fns <- lapply(envs, ls)

Turn this into a data frame, for easy use with dplyr.

fns_by_env <- data_frame(
  env = rep.int(names(fns), lengths(fns)),
  fn  = unlist(fns)
)

Find cases where the object appears more than once.

fns_by_env %>% 
  group_by(fn) %>% 
  tally() %>% 
  filter(n > 1) %>% 
  inner_join(fns_by_env)

To test this, try loading some packages with known conflicts (e.g., Hmisc, AnnotationDbi).

How do I prevent name conflict bugs?

The conflicted package throws an error with a helpful error message, whenever you try to use a variable with an ambiguous name.

library(conflicted)
library(Hmisc)
units
## Error: units found in 2 packages. You must indicate which one you want with ::
##  * Hmisc::units
##  * base::units

If you are using it in a table use this :-

  <script type="text/javascript">
   function showStuff(id, text, btn) {
    document.getElementById(id).style.display = 'table-row';
    // hide the lorem ipsum text
    document.getElementById(text).style.display = 'none';
    // hide the link
    btn.style.display = 'none';
}
</script>


<td class="post">

<a href="#" onclick="showStuff('answer1', 'text1', this); return false;">Edit</a>
<span id="answer1" style="display: none;">
<textarea rows="10" cols="115"></textarea>
</span>

<span id="text1">Lorem ipsum Lorem ipsum Lorem ipsum Lorem ipsum</span>
</td>

The correct answer is already stated (just use SortedDictionary).

However, if by chance you have some need to retain your collection as Dictionary, it is possible to access the Dictionary keys in an ordered way, by, for example, ordering the keys in a List, then using this list to access the Dictionary. An example...

Dictionary<string, int> dupcheck = new Dictionary<string, int>();

...some code that fills in "dupcheck", then...

if (dupcheck.Count > 0) {
  Console.WriteLine("\ndupcheck (count: {0})\n----", dupcheck.Count);
  var keys_sorted = dupcheck.Keys.ToList();
    keys_sorted.Sort();
  foreach (var k in keys_sorted) {
    Console.WriteLine("{0} = {1}", k, dupcheck[k]);
  }
}

Don't forget using System.Linq; for this.

You can force the annotation library in your test using:

androidTestCompile 'com.android.support:support-annotations:23.1.0'

Something like this:

  // Force usage of support annotations in the test app, since it is internally used by the runner module.
  androidTestCompile 'com.android.support:support-annotations:23.1.0'
  androidTestCompile 'com.android.support.test:runner:0.4.1'
  androidTestCompile 'com.android.support.test:rules:0.4.1'
  androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2.1'
  androidTestCompile 'com.android.support.test.espresso:espresso-intents:2.2.1'
  androidTestCompile 'com.android.support.test.espresso:espresso-web:2.2.1'

Another solution is to use this in the top level file:

configurations.all {
    resolutionStrategy.force 'com.android.support:support-annotations:23.1.0'
}

First, factor consists of indices and levels. This fact is very very important when you are struggling with factor.

For example,

> z <- factor(letters[c(3, 2, 3, 4)])

# human-friendly display, but internal structure is invisible
> z
[1] c b c d
Levels: b c d

# internal structure of factor
> unclass(z)
[1] 2 1 2 3
attr(,"levels")
[1] "b" "c" "d"

here, z has 4 elements.
The index is 2, 1, 2, 3 in that order.
The level is associated with each index: 1 -> b, 2 -> c, 3 -> d.

Then, as.numeric converts simply the index part of factor into numeric.
as.character handles the index and levels, and generates character vector expressed by its level.

?as.numeric says that Factors are handled by the default method.

Bootstrap 4 provides standard methods for this, fully described here: https://getbootstrap.com/docs/4.3/getting-started/theming

Eg. you can override defaults simply by setting variables in the SASS file, where you import bootstrap. An example from the docs (which also answers the question):

// Your variable overrides
$body-bg: #000;
$body-color: #111;

// Bootstrap and its default variables
@import "../node_modules/bootstrap/scss/bootstrap";

In a linked question, there's some Objective-C code to get the mime type for a file URL. I've created a Swift extension based on that Objective-C code to get the mime type:

import Foundation
import MobileCoreServices

extension URL {
    var mimeType: String? {
        guard self.pathExtension.count != 0 else {
            return nil
        }

        let pathExtension = self.pathExtension as CFString
        if let preferredIdentifier = UTTypeCreatePreferredIdentifierForTag(kUTTagClassFilenameExtension, pathExtension, nil) {
            guard let mimeType = UTTypeCopyPreferredTagWithClass(preferredIdentifier.takeRetainedValue(), kUTTagClassMIMEType) else {
                return nil
            }
            return mimeType.takeRetainedValue() as String
        }

        return nil
    }
}

The Answer from AaronM using the shell one-liner is good, but actually, there is yet another bug, where spaces will corrupt the user names if there are different amounts of white spaces between the user name and the date. The corrupted user names will give multiple rows for user counts and you have to sum them up yourself.

This small change fixed the issue for me:

git ls-files -z | xargs -0n1 git blame -w --show-email | perl -n -e '/^.*?\((.*?)\s+[\d]{4}/; print $1,"\n"' | sort -f | uniq -c | sort -n

Notice the + after \s which will consume all whitespaces from the name to the date.

Actually adding this answer as much for my own rememberance as for helping anyone else, since this is at least the second time I google the subject :)

• Edit 2019-01-23 Added --show-email to git blame -w to aggregate on email instead, since some people use different Name formats on different computers, and sometimes two people with the same name are working in the same git.

"View -> Show Symbol -> uncheck Show All characters" may not work if you have pending update for notepad++. So update Notepad++ and then View -> Show Symbol -> uncheck Show All characters

Hope this is helpful!

Alternatively to information_schema it is possible to use pg_tables:

select * from pg_tables where schemaname='public';

You can use the reflect package to select the fields that you want by reflecting on the field tags and selecting the json tag values. Define a method on your SearchResults type that selects the fields you want and returns them as a map[string]interface{}, and then marshal that instead of the SearchResults struct itself. Here's an example of how you might define that method:

func fieldSet(fields ...string) map[string]bool {
    set := make(map[string]bool, len(fields))
    for _, s := range fields {
        set[s] = true
    }
    return set
}

func (s *SearchResult) SelectFields(fields ...string) map[string]interface{} {
    fs := fieldSet(fields...)
    rt, rv := reflect.TypeOf(*s), reflect.ValueOf(*s)
    out := make(map[string]interface{}, rt.NumField())
    for i := 0; i < rt.NumField(); i++ {
        field := rt.Field(i)
        jsonKey := field.Tag.Get("json")
        if fs[jsonKey] {
            out[jsonKey] = rv.Field(i).Interface()
        }
    }
    return out
}

and here's a runnable solution that shows how you would call this method and marshal your selection: http://play.golang.org/p/1K9xjQRnO8

Using the default instance (i.e., MSSQLSERVER, use the DOT (.))

<add name="CONNECTION_STRING_NAME" connectionString="Data Source=.;Initial Catalog=DATABASE_NAME;Integrated Security=True;" />

It can be useful for lazy-loading. Say the object in question is stored in a database, and you don't want to go get it unless you need it. If the object is retrieved by a getter, then the internal object can be null until somebody asks for it, then you can go get it on the first call to the getter.

I had a base page class in a project that was handed to me that was loading some data from a couple different web service calls, but the data in those web service calls wasn't always used in all child pages. Web services, for all of the benefits, pioneer new definitions of "slow", so you don't want to make a web service call if you don't have to.

I moved from public fields to getters, and now the getters check the cache, and if it's not there call the web service. So with a little wrapping, a lot of web service calls were prevented.

So the getter saves me from trying to figure out, on each child page, what I will need. If I need it, I call the getter, and it goes to find it for me if I don't already have it.

    protected YourType _yourName = null;
    public YourType YourName{
      get
      {
        if (_yourName == null)
        {
          _yourName = new YourType();
          return _yourName;
        }
      }
    }

List1 = [[10,-13,17],[3,5,1],[13,11,12]]

num = 50
for i in List1[0]:num -= i
print num

You should avoid using nested selects and I would go as far to say you should never use them in the actual select part of your statement. You will be running that select for each row that is returned. This is a really expensive operation. Rather use joins. It is much more readable and the performance is much better.

In your case the query below should help. Note the cases statement is still there, but now it is a simple compare operation.

select
    p.product_id,
    p.type_id,
    p.product_name,
    p.type,
    case p.type_id when 10 then (CONCAT_WS(' ' , first_name, middle_name, last_name )) else (null) end artistC
from
    Product p

    inner join Product_Type pt on
        pt.type_id = p.type_id

    left join Product_ArtistAuthor paa on
        paa.artist_id = p.artist_id
where
    p.product_id = $pid

I used a left join since I don't know the business logic.

Another alternative is to use capturing sub-expressions with the regular expression functions regmatches and regexec.

# the original example
x <- 'hello stackoverflow'

# grab the substrings
myStrings <- regmatches(x, regexec('(^.)(.*)', x))

This returns the entire string, the first character, and the "popped" result in a list of length 1.

myStrings
[[1]]
[1] "hello stackoverflow" "h"                   "ello stackoverflow" 

which is equivalent to list(c(x, substr(x, 1, 1), substr(x, 2, nchar(x)))). That is, it contains the super set of the desired elements as well as the full string.

Adding sapply will allow this method to work for a character vector of length > 1.

# a slightly more interesting example
xx <- c('hello stackoverflow', 'right back', 'at yah')

# grab the substrings
myStrings <- regmatches(x, regexec('(^.)(.*)', xx))

This returns a list with the matched full string as the first element and the matching subexpressions captured by () as the following elements. So in the regular expression '(^.)(.*)', (^.) matches the first character and (.*) matches the remaining characters.

myStrings
[[1]]
[1] "hello stackoverflow" "h"                   "ello stackoverflow" 

[[2]]
[1] "right back" "r"          "ight back" 

[[3]]
[1] "at yah" "a"      "t yah" 

Now, we can use the trusty sapply + [ method to pull out the desired substrings.

myFirstStrings <- sapply(myStrings, "[", 2)
myFirstStrings
[1] "h" "r" "a"
mySecondStrings <- sapply(myStrings, "[", 3)
mySecondStrings
[1] "ello stackoverflow" "ight back"          "t yah"

2019's answer as this is still actively seen today

You should likely change the .container to .container-fluid, which will cause your container to stretch the entire screen. This will allow any div's inside of it to naturally stretch as wide as they need.

original hack from 2015 that still works in some situations

You should pull that div outside of the container. You're asking a div to stretch wider than its parent, which is generally not recommended practice.

If you cannot pull it out of the div for some reason, you should change the position style with this css:

.full-width-div {
    position: absolute;
    width: 100%;
    left: 0;
}

Instead of absolute, you could also use fixed, but then it will not move as you scroll.

Edit: this answer applied to an earlier version of the question that did not mention preserving local changes; the accepted answer from Tim is indeed the correct one. Thanks to qwertzguy for the heads up.

this is not your answer but is for those come here searching solution for another problem. I wanted to get sum of a column of related table conditionally. In my database Deals has many Activities I wanted to get the sum of the "amount_total" from Activities table where activities.deal_id = deal.id and activities.status = paid so i did this.

$query->withCount([
'activity AS paid_sum' => function ($query) {
            $query->select(DB::raw("SUM(amount_total) as paidsum"))->where('status', 'paid');
        }
    ]);

it returns

"paid_sum_count" => "320.00"

in Deals attribute.

This it now the sum which i wanted to get not the count.

The issue was resolved as I was having a JDK pointing to 1.7 and JRE pointing to 1.8. Check in the command prompt by typing

java -version

and

javac -version

Both should be same.  

Your @POST method should be accepting a JSON object instead of a string. Jersey uses JAXB to support marshaling and unmarshaling JSON objects (see the jersey docs for details). Create a class like:

@XmlRootElement
public class MyJaxBean {
    @XmlElement public String param1;
    @XmlElement public String param2;
}

Then your @POST method would look like the following:

@POST @Consumes("application/json")
@Path("/create")
public void create(final MyJaxBean input) {
    System.out.println("param1 = " + input.param1);
    System.out.println("param2 = " + input.param2);
}

This method expects to receive JSON object as the body of the HTTP POST. JAX-RS passes the content body of the HTTP message as an unannotated parameter -- input in this case. The actual message would look something like:

POST /create HTTP/1.1
Content-Type: application/json
Content-Length: 35
Host: www.example.com

{"param1":"hello","param2":"world"}

Using JSON in this way is quite common for obvious reasons. However, if you are generating or consuming it in something other than JavaScript, then you do have to be careful to properly escape the data. In JAX-RS, you would use a MessageBodyReader and MessageBodyWriter to implement this. I believe that Jersey already has implementations for the required types (e.g., Java primitives and JAXB wrapped classes) as well as for JSON. JAX-RS supports a number of other methods for passing data. These don't require the creation of a new class since the data is passed using simple argument passing.

HTML <FORM>

The parameters would be annotated using @FormParam:

@POST
@Path("/create")
public void create(@FormParam("param1") String param1,
                   @FormParam("param2") String param2) {
    ...
}

The browser will encode the form using "application/x-www-form-urlencoded". The JAX-RS runtime will take care of decoding the body and passing it to the method. Here's what you should see on the wire:

POST /create HTTP/1.1
Host: www.example.com
Content-Type: application/x-www-form-urlencoded;charset=UTF-8
Content-Length: 25

param1=hello&param2=world

The content is URL encoded in this case.

If you do not know the names of the FormParam's you can do the following:

@POST @Consumes("application/x-www-form-urlencoded")
@Path("/create")
public void create(final MultivaluedMap<String, String> formParams) {
    ...
}

HTTP Headers

You can using the @HeaderParam annotation if you want to pass parameters via HTTP headers:

@POST
@Path("/create")
public void create(@HeaderParam("param1") String param1,
                   @HeaderParam("param2") String param2) {
    ...
}

Here's what the HTTP message would look like. Note that this POST does not have a body.

POST /create HTTP/1.1
Content-Length: 0
Host: www.example.com
param1: hello
param2: world

I wouldn't use this method for generalized parameter passing. It is really handy if you need to access the value of a particular HTTP header though.

HTTP Query Parameters

This method is primarily used with HTTP GETs but it is equally applicable to POSTs. It uses the @QueryParam annotation.

@POST
@Path("/create")
public void create(@QueryParam("param1") String param1,
                   @QueryParam("param2") String param2) {
    ...
}

Like the previous technique, passing parameters via the query string does not require a message body. Here's the HTTP message:

POST /create?param1=hello&param2=world HTTP/1.1
Content-Length: 0
Host: www.example.com

You do have to be particularly careful to properly encode query parameters on the client side. Using query parameters can be problematic due to URL length restrictions enforced by some proxies as well as problems associated with encoding them.

HTTP Path Parameters

Path parameters are similar to query parameters except that they are embedded in the HTTP resource path. This method seems to be in favor today. There are impacts with respect to HTTP caching since the path is what really defines the HTTP resource. The code looks a little different than the others since the @Path annotation is modified and it uses @PathParam:

@POST
@Path("/create/{param1}/{param2}")
public void create(@PathParam("param1") String param1,
                   @PathParam("param2") String param2) {
    ...
}

The message is similar to the query parameter version except that the names of the parameters are not included anywhere in the message.

POST /create/hello/world HTTP/1.1
Content-Length: 0
Host: www.example.com

This method shares the same encoding woes that the query parameter version. Path segments are encoded differently so you do have to be careful there as well.

As you can see, there are pros and cons to each method. The choice is usually decided by your clients. If you are serving FORM-based HTML pages, then use @FormParam. If your clients are JavaScript+HTML5-based, then you will probably want to use JAXB-based serialization and JSON objects. The MessageBodyReader/Writer implementations should take care of the necessary escaping for you so that is one fewer thing that can go wrong. If your client is Java based but does not have a good XML processor (e.g., Android), then I would probably use FORM encoding since a content body is easier to generate and encode properly than URLs are. Hopefully this mini-wiki entry sheds some light on the various methods that JAX-RS supports.

Note: in the interest of full disclosure, I haven't actually used this feature of Jersey yet. We were tinkering with it since we have a number of JAXB+JAX-RS applications deployed and are moving into the mobile client space. JSON is a much better fit that XML on HTML5 or jQuery-based solutions.

Try umount -f /mnt/share. Works OK with NFS, never tried with cifs.

Also, take a look at autofs, it will mount the share only when accessed, and will unmount it afterworlds.

There is a good tutorial at www.howtoforge.net

you can use SpinUntil which is buildin in the .net-framework. Please note: This method causes high cpu-workload.

In my experience you can rely on dkpg's exit codes.

The return code of dpkg -s is 0 if the package is installed and 1 if it's not, so the simplest solution I found was:

dpkg -s <pkg-name> 2>/dev/null >/dev/null || sudo apt-get -y install <pkg-name>

Works fine for me...

It is used in sequence comprehensions (like Python's list-comprehensions and generators, where you may use yield too).

It is applied in combination with for and writes a new element into the resulting sequence.

Simple example (from scala-lang)

/** Turn command line arguments to uppercase */
object Main {
  def main(args: Array[String]) {
    val res = for (a <- args) yield a.toUpperCase
    println("Arguments: " + res.toString)
  }
}

The corresponding expression in F# would be

[ for a in args -> a.toUpperCase ]

or

from a in args select a.toUpperCase 

in Linq.

Ruby's yield has a different effect.

    while (numDigits-- > 0) {
        hexString.append('0');
    }
    hexString.append(hexByte);
}

I hope I can help others.

This might be useful:

objectMapper.writeValue(new File("c:\\employee.json"), employee);

// display to console
Object json = objectMapper.readValue(
     objectMapper.writeValueAsString(employee), Object.class);

System.out.println(objectMapper.writerWithDefaultPrettyPrinter()
     .writeValueAsString(json));

TRUNCATE TABLE table;

is the SQL command. In PHP, you'd use:

mysql_query('TRUNCATE TABLE table;');

This solution worked for me. I purged apache2 and reinstall. It happened after purge and install. If it is the first install, you would not face this problem.

About generating the same random number if you call it in a loop a nifty solution is to declare the new Random() object outside of the loop as a global variable.

Notice that you have to declare your instance of the Random class outside of the GetRandomInt function if you are going to be running this in a loop.

“Why is this?” you ask.

Well, the Random class actually generates pseudo random numbers, with the “seed” for the randomizer being the system time. If your loop is sufficiently fast, the system clock time will not appear different to the randomizer and each new instance of the Random class would start off with the same seed and give you the same pseudo random number.

This has a "Reverse Engineer Database" mode:

If you want to restrict your search only to files you should consider to use -type f in your search

try to use also -iname for case-insensitive search

Example:

find /path -iname 'yourstring*' -type f

You could also perform some operations on results without pipe sign or xargs

Example:

Search for files and show their size in MB

find /path -iname 'yourstring*' -type f -exec du -sm {} \;

I just added the environment variable Boost_INCLUDE_DIR or add it to the cmake command -DBoost_INCLUDE_DIR and point to the include folder.

Now, with EF Core you can convert data type transparently in your AppDbContext

protected override void OnModelCreating(ModelBuilder modelBuilder)
{
      // i.e. Store TimeSpan as string (custom)
      modelBuilder
        .Entity<YourClass>()
        .Property(x => x.YourTimeSpan)
        .HasConversion(
            timeSpan => timeSpan.ToString(), // To DB
            timeSpanString => TimeSpan.Parse(timeSpanString) // From DB
        );

    // i.e. Store TimeSpan as string (using TimeSpanToStringConverter)
    modelBuilder
        .Entity<YourClass>()
        .Property(x => x.YourTimeSpan)
        .HasConversion(new TimeSpanToStringConverter());

      // i.e. Store TimeSpan as number of ticks (custom)
      modelBuilder
        .Entity<YourClass>()
        .Property(x => x.YourTimeSpan)
        .HasConversion(
            timeSpan => timeSpan.Ticks, // To DB
            timeSpanString => TimeSpan.FromTicks(timeSpanString) // From DB
        );

    // i.e. Store TimeSpan as number of ticks (using TimeSpanToTicksConverter)
    modelBuilder
        .Entity<YourClass>()
        .Property(x => x.YourTimeSpan)
        .HasConversion(new TimeSpanToTicksConverter());
}

The R packages dplyr and sf import the operator %>% from the R package magrittr.

Help is available by using the following command:

?'%>%'

Of course the package must be loaded before by using e.g.

library(sf)

The documentation of the magrittr forward-pipe operator gives a good example: When functions require only one argument, x %>% f is equivalent to f(x)

Individual TLD's can place their own rules & restrictions on domains names as they see fit, such as to accomodate local languages.

For example, according to the CIRA, Canada's .ca domain names are allowed:

• Letters a through z, and the following accented characters: é ë ê è â à æ ô œ ù û ü ç î ï ÿ. Note that Domain Names are not case sensitive. This means there will be no distinction made between upper case letters and lower case letters (A = a);

• The numbers 0123456789, and

• The hyphen character ("-) (although it cannot be used to start or end a Domain Name).

The maximum length is 63 characters, except each accented character reduces that limit by 4 characters.

(Source)

_{Incidentally, this allows for around 4 Quadragintillion domain name possibilities (not counting sub-domains) for dot-ca domains.}

If your margin is set on the body, then setting the background color of the html tag should color the margin area

html { background-color: black; }
body { margin:50px; background-color: white; }

http://jsfiddle.net/m3zzb/

Or as dmackerman suggestions, set a margin of 0, but a border of the size you want the margin to be and set the border-color

You might have forgotten to auto increment the id field.

once I need to fix the height of a particular valued row by using inline CSS as following..

Here is my take on s soosh's and 0xA3's answers. It can update the console with user messages while updating the spinner and has an elapsed time indicator aswell.

public class ConsoleSpiner : IDisposable
{
    private static readonly string INDICATOR = "/-\\|";
    private static readonly string MASK = "\r{0} {1:c} {2}";
    int counter;
    Timer timer;
    string message;

    public ConsoleSpiner() {
        counter = 0;
        timer = new Timer(200);
        timer.Elapsed += TimerTick;
    }

    public void Start() {
        timer.Start();
    }

    public void Stop() {
        timer.Stop();
        counter = 0;
    }

    public string Message {
        get { return message; }
        set { message = value; }
    }

    private void TimerTick(object sender, ElapsedEventArgs e) {
        Turn();
    }

    private void Turn() {
        counter++;
        var elapsed = TimeSpan.FromMilliseconds(counter * 200);
        Console.Write(MASK, INDICATOR[counter % 4], elapsed, this.Message);
    }

    public void Dispose() {
        Stop();
        timer.Elapsed -= TimerTick;
        this.timer.Dispose();
    }
}

usage is something like this:

class Program
{
    static void Main(string[] args)
    {
        using (var spinner = new ConsoleSpiner())
        {
            spinner.Start();
            spinner.Message = "About to do some heavy staff :-)"
            DoWork();
            spinner.Message = "Now processing other staff".
            OtherWork();
            spinner.Stop();
        }
        Console.WriteLine("COMPLETED!!!!!\nPress any key to exit.");

    }
}

If you do not want to depend on throwing exception (which you probably should not) you can try this:

public static <T> T cast(Object o, Class<T> clazz) {
    return clazz.isInstance(o) ? clazz.cast(o) : null;
}

If your table is MyISAM:

SELECT  *
FROM    pages
WHERE   MATCH(title, content) AGAINST ('keyword' IN BOOLEAN MODE)

This will be much faster if you create a FULLTEXT index on your columns:

CREATE FULLTEXT INDEX fx_pages_title_content ON pages (title, content)

, but will work even without the index.

You can pass an ArrayList<E> the same way, if the E type is Serializable.

You would call the putExtra (String name, Serializable value) of Intent to store, and getSerializableExtra (String name) for retrieval.

Example:

ArrayList<String> myList = new ArrayList<String>();
intent.putExtra("mylist", myList);

In the other Activity:

ArrayList<String> myList = (ArrayList<String>) getIntent().getSerializableExtra("mylist");

To create a text input in which the value under the hood is a single line string but is presented to the user in a word-wrapped format you can use the contenteditable attribute on a <div> or other element:

const el = document.querySelector('div[contenteditable]');_x000D_
_x000D_
// Get value from element on input events_x000D_
el.addEventListener('input', () => console.log(el.textContent));_x000D_
_x000D_
// Set some value_x000D_
el.textContent = 'Lorem ipsum curae magna venenatis mattis, purus luctus cubilia quisque in et, leo enim aliquam consequat.'

div[contenteditable] {_x000D_
  border: 1px solid black;_x000D_
  width: 200px;_x000D_
}

<div contenteditable></div>

According to the question html5 validity should be validate able using jQuery at first and in most of the answer this is not happening and the reason for this is as following:

while validating using html5 form's default function

checkValidity();// returns true/false

we need to understand that jQuery returns object array, while selecting like this

$("#myForm")

therefore, you need to specify the first index to make checkValidity() function work

$('#myForm')[0].checkValidity()

here is the complete solution:

<button type="button" name="button" onclick="saveData()">Save</button>

function saveData()
{
    if($('#myForm')[0].checkValidity()){
        $.ajax({
          type: "POST",
          url: "save.php",
          data: data,
          success: function(resp){console.log("Response: "+resp);}
        });
    }
}

You should have used Type Casting as we can use in any other language.

If your enum is like this-

public enum Question
{
    Role = 2,
    ProjectFunding = 3,
    TotalEmployee = 4,
    NumberOfServers = 5,
    TopBusinessConcern = 6
}

And you need to cast to an int, then do this-

Question q = Question.Role;
.............
.............
int something = (int) q;

Re-

In C#, there are two types of casting:

• Implicit Casting (automatically) - converting a smaller type to a larger type size like-

char -> int -> long -> float -> double

• Explicit Casting (manually) - converting a larger type to a smaller size type like-

double -> float -> long -> int -> char

More can be found in here.

// My Enumeration Class
class Enum
{
    protected $m_actions = array();

    public function __construct($actions)
    {
        $this->init($actions);
    }

    public function init($actions)
    {
        $this->m_actions = array();
        for($i = 0; $i < count($actions); ++$i)
        {
            $this->m_actions[$actions[$i]] = ($i + 1); 
            define($actions[$i], ($i + 1));
        }
    }

    public function toString($index)
    {
        $keys = array_keys($this->m_actions);
        for($i = 0; $i < count($keys); ++$i)
        {
            if($this->m_actions[$keys[$i]] == $index)
            {
                return $keys[$i];
            }
        }

        return "undefined";
    }

    public function fromString($str)
    {
        return $this->m_actions[$str];
    }
}

// Enumeration creation
$actions = new Enum(array("CREATE", "READ", "UPDATE", "DELETE"));

// Examples
print($action_objects->toString(DELETE));
print($action_objects->fromString("DELETE"));

if($action_objects->fromString($_POST["myAction"]) == CREATE)
{
    print("CREATE");
}

I'm going to try answering my own question here, but I don't really like this, either:

for (int i = 0; i < myArray.Length; i++)
{
    int iBackwards = myArray.Length - 1 - i; // ugh
    myArray[iBackwards] = 666;
}

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

var array = ["hello","falsey","undefined"];
var findLongestWord = function(array){
    var longest = array.reduce(function(a,b){
    return (a.length > b.length) ? a : b;
  });
    return longest;
}
findLongestWord(array);

Use encode() function along with hardcoded String value given in a single quote.

Ex:

file.write(answers[i] + '\n'.encode())

OR

line.split(' +++$+++ '.encode())

   /* 1 */ Foo* foo1 = new Foo ();

Creates an object of type Foo in dynamic memory. foo1 points to it. Normally, you wouldn't use raw pointers in C++, but rather a smart pointer. If Foo was a POD-type, this would perform value-initialization (it doesn't apply here).

   /* 2 */ Foo* foo2 = new Foo;

Identical to before, because Foo is not a POD type.

   /* 3 */ Foo foo3;

Creates a Foo object called foo3 in automatic storage.

   /* 4 */ Foo foo4 = Foo::Foo();

Uses copy-initialization to create a Foo object called foo4 in automatic storage.

   /* 5 */ Bar* bar1 = new Bar ( *new Foo() );

Uses Bar's conversion constructor to create an object of type Bar in dynamic storage. bar1 is a pointer to it.

   /* 6 */ Bar* bar2 = new Bar ( *new Foo );

Same as before.

   /* 7 */ Bar* bar3 = new Bar ( Foo foo5 );

This is just invalid syntax. You can't declare a variable there.

   /* 8 */ Bar* bar3 = new Bar ( Foo::Foo() );

Would work and work by the same principle to 5 and 6 if bar3 wasn't declared on in 7.

5 & 6 contain memory leaks.

Syntax like new Bar ( Foo::Foo() ); is not usual. It's usually new Bar ( (Foo()) ); - extra parenthesis account for most-vexing parse. (corrected)

Another way based on amadan:

    SELECT * FROM [Purchasing].[Vendor] WHERE  

      ( (@url IS null OR @url = '' OR @url = 'ALL') and   PurchasingWebServiceURL LIKE '%')
    or

       ( @url = 'blank' and  PurchasingWebServiceURL = '')
    or
        (@url = 'fail' and  PurchasingWebServiceURL NOT LIKE '%treyresearch%')
    or( (@url not in ('fail','blank','','ALL') and @url is not null and 
          PurchasingWebServiceUrl Like '%'+@ur+'%') 
END

preg_replace shim with eval support

This is very inadvisable. But if you're not a programmer, or really prefer terrible code, you could use a substitute preg_replace function to keep your /e flag working temporarily.

/**
 * Can be used as a stopgap shim for preg_replace() calls with /e flag.
 * Is likely to fail for more complex string munging expressions. And
 * very obviously won't help with local-scope variable expressions.
 *
 * @license: CC-BY-*.*-comment-must-be-retained
 * @security: Provides `eval` support for replacement patterns. Which
 *   poses troubles for user-supplied input when paired with overly
 *   generic placeholders. This variant is only slightly stricter than
 *   the C implementation, but still susceptible to varexpression, quote
 *   breakouts and mundane exploits from unquoted capture placeholders.
 * @url: https://stackoverflow.com/q/15454220
 */
function preg_replace_eval($pattern, $replacement, $subject, $limit=-1) {
    # strip /e flag
    $pattern = preg_replace('/(\W[a-df-z]*)e([a-df-z]*)$/i', '$1$2', $pattern);
    # warn about most blatant misuses at least
    if (preg_match('/\(\.[+*]/', $pattern)) {
        trigger_error("preg_replace_eval(): regex contains (.*) or (.+) placeholders, which easily causes security issues for unconstrained/user input in the replacement expression. Transform your code to use preg_replace_callback() with a sane replacement callback!");
    }
    # run preg_replace with eval-callback
    return preg_replace_callback(
        $pattern,
        function ($matches) use ($replacement) {
            # substitute $1/$2/… with literals from $matches[]
            $repl = preg_replace_callback(
                '/(?<!\\\\)(?:[$]|\\\\)(\d+)/',
                function ($m) use ($matches) {
                    if (!isset($matches[$m[1]])) { trigger_error("No capture group for '$m[0]' eval placeholder"); }
                    return addcslashes($matches[$m[1]], '\"\'\`\$\\\0'); # additionally escapes '$' and backticks
                },
                $replacement
            );
            # run the replacement expression
            return eval("return $repl;");
        },
        $subject,
        $limit
    );
}

In essence, you just include that function in your codebase, and edit preg_replace to preg_replace_eval wherever the /e flag was used.

Pros and cons:

• Really just tested with a few samples from Stack Overflow.
• Does only support the easy cases (function calls, not variable lookups).
• Contains a few more restrictions and advisory notices.
• Will yield dislocated and less comprehensible errors for expression failures.
• However is still a usable temporary solution and doesn't complicate a proper transition to preg_replace_callback.
• And the license comment is just meant to deter people from overusing or spreading this too far.

Replacement code generator

Now this is somewhat redundant. But might help those users who are still overwhelmed with manually restructuring their code to preg_replace_callback. While this is effectively more time consuming, a code generator has less trouble to expand the /e replacement string into an expression. It's a very unremarkable conversion, but likely suffices for the most prevalent examples.

To use this function, edit any broken preg_replace call into preg_replace_eval_replacement and run it once. This will print out the according preg_replace_callback block to be used in its place.

/**
 * Use once to generate a crude preg_replace_callback() substitution. Might often
 * require additional changes in the `return …;` expression. You'll also have to
 * refit the variable names for input/output obviously.
 *
 * >>>  preg_replace_eval_replacement("/\w+/", 'strtopupper("$1")', $ignored);
 */
function preg_replace_eval_replacement($pattern, $replacement, $subjectvar="IGNORED") {
    $pattern = preg_replace('/(\W[a-df-z]*)e([a-df-z]*)$/i', '$1$2', $pattern);
    $replacement = preg_replace_callback('/[\'\"]?(?<!\\\\)(?:[$]|\\\\)(\d+)[\'\"]?/', function ($m) { return "\$m[{$m[1]}]"; }, $replacement);
    $ve = "var_export";
    $bt = debug_backtrace(0, 1)[0];
    print "<pre><code>
    #----------------------------------------------------
    # replace preg_*() call in '$bt[file]' line $bt[line] with:
    #----------------------------------------------------
    \$OUTPUT_VAR = preg_replace_callback(
        {$ve($pattern, TRUE)},
        function (\$m) {
            return {$replacement};
        },
        \$YOUR_INPUT_VARIABLE_GOES_HERE
    )
    #----------------------------------------------------
    </code></pre>\n";
}

Take in mind that mere copy&pasting is not programming. You'll have to adapt the generated code back to your actual input/output variable names, or usage context.

• Specificially the $OUTPUT = assignment would have to go if the previous preg_replace call was used in an if.
• It's best to keep temporary variables or the multiline code block structure though.

And the replacement expression may demand more readability improvements or rework.

• For instance stripslashes() often becomes redundant in literal expressions.
• Variable-scope lookups require a use or global reference for/within the callback.
• Unevenly quote-enclosed "-$1-$2" capture references will end up syntactically broken by the plain transformation into "-$m[1]-$m[2].

The code output is merely a starting point. And yes, this would have been more useful as an online tool. This code rewriting approach (edit, run, edit, edit) is somewhat impractical. Yet could be more approachable to those who are accustomed to task-centric coding (more steps, more uncoveries). So this alternative might curb a few more duplicate questions.

In powershell:

Get-Content file1.txt | Out-File out.txt
Get-Content file2.txt | Select-Object -Skip 1 | Out-File -Append out.txt

• In SQLDeveloper browse Tools --> Preferences, as shown in below image.
  
  
  
  
• In the Preferences options expand Database --> select Advanced --> under "Tnsnames Directory" --> Browse the directory where tnsnames.ora present.
  
• Then click on Ok, as shown in below diagram.
  tnsnames.ora available at Drive:\oracle\product\10x.x.x\client_x\NETWORK\ADMIN
  
  

Now you can connect via the TNSnames options.

If it is a parameter in a function, you can validate it with ValidateNotNullOrEmpty as you can see in this example:

Function Test-Something
{
    Param(
        [Parameter(Mandatory=$true)]
        [ValidateNotNullOrEmpty()]
        [string]$UserName
    )

    #stuff todo
}

Another simple way get by using findall in yii

$id =101; 
$comments = EmailArchive::model()->findAll(array("condition"=>"':email_id'=$id"));
foreach($comments as $comments_1) 
{ 
echo  "email:".$comments_1['email_id'];
}

Use git rebase --abort. From the official Linux kernel documentation for git rebase:

git rebase --continue | --skip | --abort | --edit-todo

Try this:

if( $this->container->get('security.context')->isGranted('IS_AUTHENTICATED_FULLY') ){
    // authenticated (NON anonymous)
}

Further information:

To complement ruslik's answer, in C++14 you can use this construction:

delete std::exchange(heapObject, nullptr);

In C, it is a common idiom to zero out the memory for a struct using memset:

struct x myStruct;
memset(&myStruct, 0, sizeof(myStruct));

Technically speaking, I don't believe that this is portable because it assumes that the NULL pointer on a machine is represented by the integer value 0, but it's used widely because on most machines this is the case.

If you move from C to C++, be careful not to use this technique on every object. C++ only makes this legal on objects with no member functions and no inheritance.

int? here = (list.ElementAtOrDefault(2) != 0 ? list[2]:(int?) null);

With only 1 IP you can forget DNS but you can use a MineProxy because the handshake packet of the client contains the host that then he connected to and a MineProxy will ready this host and proxy the connection to a server that is registered for that host

Using TortoiseSVN worked easily on Windows for me.

http://tortoisesvn.net/

Right click file -> TortoiseSVN menu -> Repo-browser -> right click file in repository -> rename -> press Enter -> click Ok

Using SVN 1.8.8 TortoiseSVN version 1.8.5

Another thing to check is whether you have Windows Firewall enabled, since that might be blocking port 42424.

If any of the things above do not work, make a back of Xampp directory and reinstall Xampp. That surely works!

Swamibebop's solution works, but by taking advantage of table.* syntax, we can avoid repeating the column names of the inner select and get a simpler/shorter result:

SELECT @r := @r+1 , 
       z.* 
FROM(/* your original select statement goes in here */)z, 
(SELECT @r:=0)y;

So that will give you:

SELECT @r := @r+1 , 
       z.* 
FROM(
     SELECT itemID, 
     count(*) AS ordercount
     FROM orders
     GROUP BY itemID
     ORDER BY ordercount DESC
    )z,
    (SELECT @r:=0)y;

You should follow the guidelines on Add a secondary horizontal axis:

Add a secondary horizontal axis

To complete this procedure, you must have a chart that displays a secondary vertical axis. To add a secondary vertical axis, see Add a secondary vertical axis.

1. Click a chart that displays a secondary vertical axis. This displays the Chart Tools, adding the Design, Layout, and Format tabs.

2. On the Layout tab, in the Axes group, click Axes.

   

3. Click Secondary Horizontal Axis, and then click the display option that you want.

Add a secondary vertical axis

You can plot data on a secondary vertical axis one data series at a time. To plot more than one data series on the secondary vertical axis, repeat this procedure for each data series that you want to display on the secondary vertical axis.

1. In a chart, click the data series that you want to plot on a secondary vertical axis, or do the following to select the data series from a list of chart elements:

   • Click the chart.

     This displays the Chart Tools, adding the Design, Layout, and Format tabs.

   • On the Format tab, in the Current Selection group, click the arrow in the Chart Elements box, and then click the data series that you want to plot along a secondary vertical axis.

     

2. On the Format tab, in the Current Selection group, click Format Selection. The Format Data Series dialog box is displayed.

   Note: If a different dialog box is displayed, repeat step 1 and make sure that you select a data series in the chart.

3. On the Series Options tab, under Plot Series On, click Secondary Axis and then click Close.

   A secondary vertical axis is displayed in the chart.

4. To change the display of the secondary vertical axis, do the following:

   • On the Layout tab, in the Axes group, click Axes.

   • Click Secondary Vertical Axis, and then click the display option that you want.

5. To change the axis options of the secondary vertical axis, do the following:

   • Right-click the secondary vertical axis, and then click Format Axis.

   • Under Axis Options, select the options that you want to use.

d stands for Declaration Files:

When a TypeScript script gets compiled there is an option to generate a declaration file (with the extension .d.ts) that functions as an interface to the components in the compiled JavaScript. In the process the compiler strips away all function and method bodies and preserves only the signatures of the types that are exported. The resulting declaration file can then be used to describe the exported virtual TypeScript types of a JavaScript library or module when a third-party developer consumes it from TypeScript.

The concept of declaration files is analogous to the concept of header file found in C/C++.

declare module arithmetics {
    add(left: number, right: number): number;
    subtract(left: number, right: number): number;
    multiply(left: number, right: number): number;
    divide(left: number, right: number): number;
}

Type declaration files can be written by hand for existing JavaScript libraries, as has been done for jQuery and Node.js.

Large collections of declaration files for popular JavaScript libraries are hosted on GitHub in DefinitelyTyped and the Typings Registry. A command-line utility called typings is provided to help search and install declaration files from the repositories.

U can use above code

Regarding the first (and great) answer from chris who proposed a solution to the situation where the class members are held as a "true composite" members (i.e.- not as pointers nor references):

The note is a bit large, so I will demonstrate it here with some sample code.

When you chose to hold the members as I mentioned, you have to keep in mind also these two things:

1. For every "composed object" that does not have a default constructor - you must initialize it in the initialization list of all the constructor's of the "father" class (i.e.- BigMommaClass or MyClass in the original examples and MyClass in the code below), in case there are several (see InnerClass1 in the example below). Meaning, you can "comment out" the m_innerClass1(a) and m_innerClass1(15) only if you enable the InnerClass1 default constructor.

2. For every "composed object" that does have a default constructor - you may initialize it within the initialization list, but it will work also if you chose not to (see InnerClass2 in the example below).

See sample code (compiled under Ubuntu 18.04 (Bionic Beaver) with g++ version 7.3.0):

#include <iostream>

using namespace std;

class InnerClass1
{
    public:
        InnerClass1(int a) : m_a(a)
        {
            cout << "InnerClass1::InnerClass1 - set m_a:" << m_a << endl;
        }

        /* No default constructor
        InnerClass1() : m_a(15)
        {
            cout << "InnerClass1::InnerClass1() - set m_a:" << m_a << endl;
        }
        */

        ~InnerClass1()
        {
            cout << "InnerClass1::~InnerClass1" << endl;
        }

    private:
        int m_a;
};

class InnerClass2
{
    public:
        InnerClass2(int a) : m_a(a)
        {
            cout << "InnerClass2::InnerClass2 - set m_a:" << m_a << endl;
        }

        InnerClass2() : m_a(15)
        {
            cout << "InnerClass2::InnerClass2() - set m_a:" << m_a << endl;
        }

        ~InnerClass2()
        {
            cout << "InnerClass2::~InnerClass2" << endl;
        }

    private:
        int m_a;
};

class MyClass
{
    public:
        MyClass(int a, int b) : m_innerClass1(a), /* m_innerClass2(a),*/ m_b(b)
        {
            cout << "MyClass::MyClass(int b) - set m_b to:" << m_b << endl;
        }

         MyClass() : m_innerClass1(15), /*m_innerClass2(15),*/ m_b(17)
        {
            cout << "MyClass::MyClass() - m_b:" << m_b << endl;
        }

        ~MyClass()
        {
            cout << "MyClass::~MyClass" << endl;
        }

    private:
        InnerClass1 m_innerClass1;
        InnerClass2 m_innerClass2;
        int m_b;
};

int main(int argc, char** argv)
{
    cout << "main - start" << endl;

    MyClass obj;

    cout << "main - end" << endl;
    return 0;
}

I had a similar problem with R-studio. When I tried to do my plots, this message was showing up.

Eventually I realised that the reason behind this was that my "window" for the plots was too small, and I had to make it bigger to "fit" all the plots inside!

Hope to help

One explanation might be floating point rounding issues. For example, if you could call

range(0, 0.4, 0.1)

you might expect an output of

[0, 0.1, 0.2, 0.3]

but you in fact get something like

[0, 0.1, 0.2000000001, 0.3000000001]

due to rounding issues. And since range is often used to generate indices of some sort, it's integers only.

Still, if you want a range generator for floats, you can just roll your own.

def xfrange(start, stop, step):
    i = 0
    while start + i * step < stop:
        yield start + i * step
        i += 1

First add your item to mItems and then use:

mAdapter.notifyItemInserted(mItems.size() - 1);

this method is better than using:

mAdapter.notifyDataSetChanged();

in performance.

Console.Read() reads just a single character, while Console.ReadLine() reads all characters until the end of line.

You could try updating the table to get rid of these characters:

UPDATE dbo.[audit]
  SET UserID = REPLACE(UserID, CHAR(0), '')
  WHERE CHARINDEX(CHAR(0), UserID) > 0;

But then you'll also need to fix whatever is putting this bad data into the table in the first place. In the meantime perhaps try:

SELECT CONVERT(INT, REPLACE(UserID, CHAR(0), ''))
  FROM dbo.[audit];

But that is not a long term solution. Fix the data (and the data type while you're at it). If you can't fix the data type immediately, then you can quickly find the culprit by adding a check constraint:

ALTER TABLE dbo.[audit]
  ADD CONSTRAINT do_not_allow_stupid_data
  CHECK (CHARINDEX(CHAR(0), UserID) = 0);

EDIT

Ok, so that is definitely a 4-digit integer followed by six instances of CHAR(0). And the workaround I posted definitely works for me:

DECLARE @foo TABLE(UserID VARCHAR(32));
INSERT @foo SELECT 0x31353831000000000000;

-- this succeeds:
SELECT CONVERT(INT, REPLACE(UserID, CHAR(0), '')) FROM @foo;

-- this fails:
SELECT CONVERT(INT, UserID) FROM @foo;

Please confirm that this code on its own (well, the first SELECT, anyway) works for you. If it does then the error you are getting is from a different non-numeric character in a different row (and if it doesn't then perhaps you have a build where a particular bug hasn't been fixed). To try and narrow it down you can take random values from the following query and then loop through the characters:

SELECT UserID, CONVERT(VARBINARY(32), UserID)
  FROM dbo.[audit]
  WHERE UserID LIKE '%[^0-9]%';

So take a random row, and then paste the output into a query like this:

DECLARE @x VARCHAR(32), @i INT;
SET @x = CONVERT(VARCHAR(32), 0x...); -- paste the value here
SET @i = 1;
WHILE @i <= LEN(@x)
BEGIN
  PRINT RTRIM(@i) + ' = ' + RTRIM(ASCII(SUBSTRING(@x, @i, 1)))
  SET @i = @i + 1;
END

This may take some trial and error before you encounter a row that fails for some other reason than CHAR(0) - since you can't really filter out the rows that contain CHAR(0) because they could contain CHAR(0) and CHAR(something else). For all we know you have values in the table like:

SELECT '15' + CHAR(9) + '23' + CHAR(0);

...which also can't be converted to an integer, whether you've replaced CHAR(0) or not.

I know you don't want to hear it, but I am really glad this is painful for people, because now they have more war stories to push back when people make very poor decisions about data types.

You might want to take a look at (and maybe expand) my little tool kqwait. Currently it just sits around and waits for a write event on a single file, but the kqueue architecture allows for hierarchical event stacking...

Okay adding to @null's awesome post about using the Asset Catalog.

You may need to do the following to get the App's Icon linked and working for Ad-Hoc distributions / production to be seen in Organiser, Test flight and possibly unknown AppStore locations.

After creating the Asset Catalog, take note of the name of the Launch Images and App Icon names listed in the .xassets in Xcode.

By Default this should be

• AppIcon
• LaunchImage

[To see this click on your .xassets folder/icon in Xcode.] (this can be changed, so just take note of this variable for later)

What is created now each build is the following data structures in your .app:

For App Icons:

iPhone

• AppIcon57x57.png (iPhone non retina) [Notice the Icon name prefix]
• [email protected] (iPhone retina)

And the same format for each of the other icon resolutions.

iPad

• AppIcon72x72~ipad.png (iPad non retina)
• AppIcon72x72@2x~ipad.png (iPad retina)

(For iPad it is slightly different postfix)

Main Problem

Now I noticed that in my Info.plist in Xcode 5.0.1 it automatically attempted and failed to create a key for "Icon files (iOS 5)" after completing the creation of the Asset Catalog.

If it did create a reference successfully / this may have been patched by Apple or just worked, then all you have to do is review the image names to validate the format listed above.

Final Solution:

Add the following key to you main .plist

I suggest you open your main .plist with a external text editor such as TextWrangler rather than in Xcode to copy and paste the following key in.

<key>CFBundleIcons</key>
<dict>
    <key>CFBundlePrimaryIcon</key>
    <dict>
        <key>CFBundleIconFiles</key>
        <array>
            <string>AppIcon57x57.png</string>
            <string>[email protected]</string>
            <string>AppIcon72x72~ipad.png</string>
            <string>AppIcon72x72@2x~ipad.png</string>
        </array>
    </dict>
</dict>

Please Note I have only included my example resolutions, you will need to add them all.

If you want to add this Key in Xcode without an external editor, Use the following:

• Icon files (iOS 5) - Dictionary
• Primary Icon - Dictionary
• Icon files - Array
• Item 0 - String = AppIcon57x57.png And for each other item / app icon.

Now when you finally archive your project the final .xcarchive payload .plist will now include the above stated icon locations to build and use.

Do not add the following to any .plist: Just an example of what Xcode will now generate for your final payload

<key>IconPaths</key>
<array>
    <string>Applications/Example.app/AppIcon57x57.png</string>
    <string>Applications/Example.app/[email protected]</string>
    <string>Applications/Example.app/AppIcon72x72~ipad.png</string>
    <string>Applications/Example.app/AppIcon72x72@2x~ipad.png</string>
</array>

using(var myDb = new MyDbEntities())
{

    user user = new user();
    user.username = "me";
    user.email = "[email protected]";

    myDb.Users.Add(user);
    myDb.users.Attach(user);
    myDb.Entry(user).State = EntityState.Modified;//this is for modiying/update existing entry
    myDb.SaveChanges();
}

Here is a modern approach, using globalThis, we took for our React Native app.

globalThis is now included in...

• Modern browsers - MDN documentation
• Typescript 3.4 - Handbook documentation
• ESLint v7 - Release notes

_{appGlobals.ts}

// define our parent property accessible via globalThis. Also apply the TypeScript type.
var app: globalAppVariables;

// define the child properties and their types. 
type globalAppVariables = {
  messageLimit: number;
  // more can go here. 
};

// set the values.
globalThis.app = {
  messageLimit: 10,
  // more can go here.
};


// Freeze so these can only be defined in this file.
Object.freeze(globalThis.app);

_{App.tsx (our main entry point file)}

import './appGlobals'

// other code

_{anyWhereElseInTheApp.tsx}

const chatGroupQuery = useQuery(GET_CHAT_GROUP_WITH_MESSAGES_BY_ID, {
  variables: {
    chatGroupId,
    currentUserId: me.id,
    messageLimit: globalThis.app.messageLimit, //  used here.
  },
});

Here's a variation on @SiegeX's excellent *-printing solution for bash with support for backspace added; this allows the user to correct their entry with the backspace key (delete key on a Mac), as is typically supported by password prompts:

#!/usr/bin/env bash

password=''
while IFS= read -r -s -n1 char; do
  [[ -z $char ]] && { printf '\n'; break; } # ENTER pressed; output \n and break.
  if [[ $char == $'\x7f' ]]; then # backspace was pressed
      # Remove last char from output variable.
      [[ -n $password ]] && password=${password%?}
      # Erase '*' to the left.
      printf '\b \b' 
  else
    # Add typed char to output variable.
    password+=$char
    # Print '*' in its stead.
    printf '*'
  fi
done

Note:

• As for why pressing backspace records character code 0x7f: "In modern systems, the backspace key is often mapped to the delete character (0x7f in ASCII or Unicode)" ^{https://en.wikipedia.org/wiki/Backspace}
• \b \b is needed to give the appearance of deleting the character to the left; just using \b moves the cursor to the left, but leaves the character intact (nondestructive backspace). By printing a space and moving back again, the character appears to have been erased (thanks, The "backspace" escape character '\b' in C, unexpected behavior?).

In a POSIX-only shell (e.g., sh on Debian and Ubuntu, where sh is dash), use the stty -echo approach (which is suboptimal, because it prints nothing), because the read builtin will not support the -s and -n options.

If the repository is on GitHub, you can use the open source Android app Octodroid which displays the size of the repository by default.

For example, with the mptcp repository:

Disclaimer: I didn't create Octodroid.

In short, services set to Automatic will start during the boot process, while services set to start as Delayed will start shortly after boot.

Starting your service Delayed improves the boot performance of your server and has security benefits which are outlined in the article Adriano linked to in the comments.

Update: "shortly after boot" is actually 2 minutes after the last "automatic" service has started, by default. This can be configured by a registry key, according to Windows Internals and other sources (3,4).

The registry keys of interest (At least in some versions of windows) are:

• HKLM\SYSTEM\CurrentControlSet\services\<service name>\DelayedAutostart will have the value 1 if delayed, 0 if not.
• HKLM\SYSTEM\CurrentControlSet\services\AutoStartDelay or HKLM\SYSTEM\CurrentControlSet\Control\AutoStartDelay (on Windows 10): decimal number of seconds to wait, may need to create this one. Applies globally to all Delayed services.

By using this query you can see all open transactions.

List All:

SHOW FULL PROCESSLIST  

if you want to kill a hang transaction copy transaction id and kill transaction by using this command:

KILL <id>    // e.g KILL 16543

If you need a weak reference to the cell value:

object field = d.Rows[0][3]

or

object field = d.Rows[0].ItemArray[3]

Should do it

If you need a strongly typed reference (string in your case) you can use the DataRowExtensions.Field extension method:

string field = d.Rows[0].Field<string>(3);

(make sure System.Data is in listed in the namespaces in this case)

Indexes are 0 based so we first access the first row (0) and then the 4th column in this row (3)

SELECT COUNT( * )   
FROM agents   
HAVING COUNT(*)>3;

Were I you I would do something like this:

Before doing anything please keep a copy (better safe than sorry)

git checkout master
git checkout -b temp 
git reset --hard <sha-1 of your first commit> 
git add .
git commit -m 'Squash all commits in single one'
git push origin temp

After doing that you can delete other branches.

Result: You are going to have a branch with only 2 commits.

Use git log --oneline to see your commits in a minimalistic way and to find SHA-1 for commits!

Can't you import it as a git project and then (if you have the m2eclipse installed) right click on the project in the Package Explorer > Maven > Enable Dependency Management?

The fact that Clang compiles code faster may not be as important as the speed of the resulting binary. However, here is a series of benchmarks.

You Can Try This

$("p:first").css("background-color", "#B2E0FF").css("border", "3px solid red");

You can use time and subshell ():

time (
  for (( i=1; i<10000; i++ )); do
    echo 1 >/dev/null
  done
)

Or in same shell {}:

time {
  for (( i=1; i<10000; i++ )); do
    echo 1 >/dev/null
  done
}

It depends.

The main point is to avoid repeated code.

If the same code need to be re-used 2 times or more, and should be in sync when change, use external style sheet.

If you only use it once, I think inline is ok.

You can use peseudo elements like this:

input[type=checkbox] {_x000D_
  width: 30px;_x000D_
  height: 30px;_x000D_
  margin-right: 8px;_x000D_
  cursor: pointer;_x000D_
  font-size: 27px;_x000D_
}_x000D_
_x000D_
input[type=checkbox]:after {_x000D_
  content: " ";_x000D_
  background-color: #9FFF9D;_x000D_
  display: inline-block;_x000D_
  visibility: visible;_x000D_
}_x000D_
_x000D_
input[type=checkbox]:checked:after {_x000D_
  content: "\2714";_x000D_
}

<label>Checkbox label_x000D_
      <input type="checkbox">_x000D_
    </label>

You've got a few things going on there. One, why a class? Do you actually have multiple of these on the page? The CSS suggests you can't. If not you should use an ID - it's faster to select both in CSS and jQuery:

<div id=bottomMenu>You read it all.</div>

Second you've got a few crazy things going on in that CSS - in particular the z-index is supposed to just be a number, not measured in pixels. It specifies what layer this tag is on, where each higher number is closer to the user (or put another way, on top of/occluding tags with lower z-indexes).

The animation you're trying to do is basically .fadeIn(), so just set the div to display: none; initially and use .fadeIn() to animate it:

$('#bottomMenu').fadeIn(2000);

.fadeIn() works by first doing display: (whatever the proper display property is for the tag), opacity: 0, then gradually ratcheting up the opacity.

Full working example:

http://jsfiddle.net/b9chris/sMyfT/

CSS:

#bottomMenu {
    display: none;
    position: fixed;
    left: 0; bottom: 0;
    width: 100%; height: 60px;
    border-top: 1px solid #000;
    background: #fff;
    z-index: 1;
}

JS:

var $win = $(window);

function checkScroll() {
    if ($win.scrollTop() > 100) {
        $win.off('scroll', checkScroll);
        $('#bottomMenu').fadeIn(2000);
    }
}

$win.scroll(checkScroll);

You can determine if as certain word is found in a cell by using

If InStr(cell.Value, "Word1") > 0 Then

If Word1 is found in the string the InStr() function will return the location of the first character of Word1 in the string.

An alternative solution to floats is to use absolute positioning:

.title {
  position: relative;
}

.title span:last-child {
  position: absolute;
  right: 6px;   /* must be equal to parent's right padding */

You can use this snippet to validate 16 digits card numbers with the Luhn algorithm:

function validateCardNumber(number) {
    var regex = new RegExp("^[0-9]{16}$");
    if (!regex.test(number))
        return false;

    return luhnCheck(number);
}

function luhnCheck(val) {
    var sum = 0;
    for (var i = 0; i < val.length; i++) {
        var intVal = parseInt(val.substr(i, 1));
        if (i % 2 == 0) {
            intVal *= 2;
            if (intVal > 9) {
                intVal = 1 + (intVal % 10);
            }
        }
        sum += intVal;
    }
    return (sum % 10) == 0;
}

i have the same problem from my office network. i use this command but its not working for me url, so like this: before $ git clone https://gitlab.com/omsharma/Resume.git

After i Use this URL : $ git clone https://[email protected]/omsharma/Resume.git try It.

using sqldf fits here:

library(sqldf)
sqldf("SELECT Believe, Count(1) as N FROM Santa
       GROUP BY Believe")

Put this in your Program.cs:

FormName FormName = new FormName ();

FormName.ShowInTaskbar = false;
FormName.Opacity = 0;
FormName.Show();
FormName.Hide();

Use this when you want to display the form:

var principalForm = Application.OpenForms.OfType<FormName>().Single();
principalForm.ShowInTaskbar = true;
principalForm.Opacity = 100;
principalForm.Show();

Using foreach would be shorter code, but probably do exactly the same steps at runtime after JIT optimization recognizes the comparison to Length in the for-loop controlling expression.

The jar file is missing. You can download the jar file and add it as external libraries in your project . You can download this from

http://www.findjar.com/jar/com/googlecode/json-simple/json-simple/1.1/json-simple-1.1.jar.html

Parsing the query string is a bit more complicated than it seems, depending on how forgiving you want to be.

First, the query string is ascii bytes. You read in these bytes one at a time and convert them to characters. If the character is ? or & then it signals the start of a parameter name. If the character is = then it signals the start of a paramter value. If the character is % then it signals the start of an encoded byte. Here is where it gets tricky.

When you read in a % char you have to read the next two bytes and interpret them as hex digits. That means the next two bytes will be 0-9, a-f or A-F. Glue these two hex digits together to get your byte value. But remember, bytes are not characters. You have to know what encoding was used to encode the characters. The character é does not encode the same in UTF-8 as it does in ISO-8859-1. In general it's impossible to know what encoding was used for a given character set. I always use UTF-8 because my web site is configured to always serve everything using UTF-8 but in practice you can't be certain. Some user-agents will tell you the character encoding in the request; you can try to read that if you have a full HTTP request. If you just have a url in isolation, good luck.

Anyway, assuming you are using UTF-8 or some other multi-byte character encoding, now that you've decoded one encoded byte you have to set it aside until you capture the next byte. You need all the encoded bytes that are together because you can't url-decode properly one byte at a time. Set aside all the bytes that are together then decode them all at once to reconstruct your character.

Plus it gets more fun if you want to be lenient and account for user-agents that mangle urls. For example, some webmail clients double-encode things. Or double up the ?&= chars (for example: http://yoursite.com/blah??p1==v1&&p2==v2). If you want to try to gracefully deal with this, you will need to add more logic to your parser.

To highlight a block of code in Notepad++, please do the following steps

1. Select the required text.
2. Right click to display the context menu
3. Choose Style token and select any of the five choices available ( styles from Using 1st style to using 5th style). Each is of different colors.If you want yellow color choose using 3rd style.

If you want to create your own style you can use Style Configurator under Settings menu.

I suggest an improvement of the Adam's answer accepting HashMap as parameter

/**
 * Append parameters to given url
 * @param url
 * @param parameters
 * @return new String url with given parameters
 * @throws URISyntaxException
 */
public static String appendToUrl(String url, HashMap<String, String> parameters) throws URISyntaxException
{
    URI uri = new URI(url);
    String query = uri.getQuery();

    StringBuilder builder = new StringBuilder();

    if (query != null)
        builder.append(query);

    for (Map.Entry<String, String> entry: parameters.entrySet())
    {
        String keyValueParam = entry.getKey() + "=" + entry.getValue();
        if (!builder.toString().isEmpty())
            builder.append("&");

        builder.append(keyValueParam);
    }

    URI newUri = new URI(uri.getScheme(), uri.getAuthority(), uri.getPath(), builder.toString(), uri.getFragment());
    return newUri.toString();
}

Use an iterator.

List comprehension:

>>> si = iter(['abcd', 'e', 'fg', 'hijklmn', 'opq', 'r'])
>>> [c+next(si, '') for c in si]
['abcde', 'fghijklmn', 'opqr']

• Very efficient for memory usage.
• Exactly one traversal of s

Generator expression:

>>> si = iter(['abcd', 'e', 'fg', 'hijklmn', 'opq', 'r'])
>>> pair_iter = (c+next(si, '') for c in si)
>>> pair_iter # can be used in a for loop
<generator object at 0x4ccaa8>
>>> list(pair_iter) 
['abcde', 'fghijklmn', 'opqr']

• use as an iterator

Using map, str.__add__, iter

>>> si = iter(['abcd', 'e', 'fg', 'hijklmn', 'opq', 'r'])
>>> map(str.__add__, si, si)
['abcde', 'fghijklmn', 'opqr']

next(iterator[, default]) is available starting in Python 2.6

The most important thing, that all are missing here is... The launchMode of FirstActivity must be singleTop. If it is singleInstance, the onActivityResult in FragmentA will be called just after calling the startActivityForResult method. So, It will not wait for calling of the finish() method in SecondActivity.

So go through the following steps, It will definitely work as it worked for me too after a long research.

In AndroidManifest.xml file, make launchMode of FirstActivity.Java as singleTop.

<activity
        android:name=".FirstActivity"
        android:label="@string/title_activity_main"
        android:launchMode="singleTop"
        android:theme="@style/AppTheme.NoActionBar" />

In FirstActivity.java, override onActivityResult method. As this will call the onActivityResult of FragmentA.

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

In FragmentA.Java, override onActivityResult method

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    Log.d("FragmentA.java","onActivityResult called");
}

Call startActivityForResult(intent, HOMEWORK_POST_ACTIVITY); from FragmentA.Java

Call finish(); method in SecondActivity.java

Hope this will work.

While it may work on some platforms, be aware that platform.architecture is not always a reliable way to determine whether python is running in 32-bit or 64-bit. In particular, on some OS X multi-architecture builds, the same executable file may be capable of running in either mode, as the example below demonstrates. The quickest safe multi-platform approach is to test sys.maxsize on Python 2.6, 2.7, Python 3.x.

$ arch -i386 /usr/local/bin/python2.7
Python 2.7.9 (v2.7.9:648dcafa7e5f, Dec 10 2014, 10:10:46)

Type "help", "copyright", "credits" or "license" for more information.
>>> import platform, sys
>>> platform.architecture(), sys.maxsize

I know this question has already been answered. However, for those using spring boot, this link helped me - https://smarterco.de/java-load-file-classpath-spring-boot/

However, the resourceLoader.getResource("classpath:file.txt").getFile(); was causing this problem and sbk's comment:

That's it. A java.io.File represents a file on the file system, in a directory structure. The Jar is a java.io.File. But anything within that file is beyond the reach of java.io.File. As far as java is concerned, until it is uncompressed, a class in jar file is no different than a word in a word document.

helped me understand why to use getInputStream() instead. It works for me now!

Thanks!

Just wanted to point out one thing missing in LazyOne's answer (I would have just commented under the answer but don't have enough rep)

In rule #2 for permanent redirect there is thing missing:

redirectType="Permanent"

So rule #2 should look like this:

<system.webServer>
    <rewrite>
        <rules>
            <rule name="SpecificRedirect" stopProcessing="true">
                <match url="^page$" />
                <action type="Redirect" url="/page.html" redirectType="Permanent" />
            </rule>
        </rules>
    </rewrite>
</system.webServer>

Edit

For more information on how to use the URL Rewrite Module see this excellent documentation: URL Rewrite Module Configuration Reference

In response to @kneidels question from the comments; To match the url: topic.php?id=39 something like the following could be used:

<system.webServer>
  <rewrite>
    <rules>
      <rule name="SpecificRedirect" stopProcessing="true">
        <match url="^topic.php$" />
        <conditions logicalGrouping="MatchAll">
          <add input="{QUERY_STRING}" pattern="(?:id)=(\d{2})" />
        </conditions>
        <action type="Redirect" url="/newpage/{C:1}" appendQueryString="false" redirectType="Permanent" />
      </rule>
    </rules>
  </rewrite>
</system.webServer>

This will match topic.php?id=ab where a is any number between 0-9 and b is also any number between 0-9. It will then redirect to /newpage/xy where xy comes from the original url. I have not tested this but it should work.

I really liked Shavais' post, but I added one more test case ( & the built in isdigit() function):

def isInt_loop(v):
    v = str(v).strip()
    # swapping '0123456789' for '9876543210' makes nominal difference (might have because '1' is toward the beginning of the string)
    numbers = '0123456789'
    for i in v:
        if i not in numbers:
            return False
    return True

def isInt_Digit(v):
    v = str(v).strip()
    return v.isdigit()

and it significantly consistently beats the times of the rest:

timings..
isInt_try:   0.4628
isInt_str:   0.3556
isInt_re:    0.4889
isInt_re2:   0.2726
isInt_loop:   0.1842
isInt_Digit:   0.1577

using normal 2.7 python:

$ python --version
Python 2.7.10

Both the two test cases I added (isInt_loop and isInt_digit) pass the exact same test cases (they both only accept unsigned integers), but I thought that people could be more clever with modifying the string implementation (isInt_loop) opposed to the built in isdigit() function, so I included it, even though there's a slight difference in execution time. (and both methods beat everything else by a lot, but don't handle the extra stuff: "./+/-" )

Also, I did find it interesting to note that the regex (isInt_re2 method) beat the string comparison in the same test that was performed by Shavais in 2012 (currently 2018). Maybe the regex libraries have been improved?

To stop the user from getting annoyed when the whole text gets selected every time they try to move the caret using their mouse, you should do this using the focus event, not the click event. The following will do the job and works around a problem in Chrome that prevents the simplest version (i.e. just calling the textarea's select() method in a focus event handler) from working.

jsFiddle: http://jsfiddle.net/NM62A/

Code:

<textarea id="foo">Some text</textarea>

<script type="text/javascript">
    var textBox = document.getElementById("foo");
    textBox.onfocus = function() {
        textBox.select();

        // Work around Chrome's little problem
        textBox.onmouseup = function() {
            // Prevent further mouseup intervention
            textBox.onmouseup = null;
            return false;
        };
    };
</script>

jQuery version:

$("#foo").focus(function() {
    var $this = $(this);
    $this.select();

    // Work around Chrome's little problem
    $this.mouseup(function() {
        // Prevent further mouseup intervention
        $this.unbind("mouseup");
        return false;
    });
});

I use these two plugins,

1. [react-native-svg] https://github.com/react-native-community/react-native-svg)
2. [ react-native-svg-transformer] https://github.com/kristerkari/react-native-svg-transformer)

First off all, You need to install that plugin. After that you need to change your metro.config.js, with this code.

const { getDefaultConfig } = require("metro-config");

module.exports = (async () => {
  const {
    resolver: { sourceExts, assetExts }
  } = await getDefaultConfig();
  return {
    transformer: {
      babelTransformerPath: require.resolve("react-native-svg-transformer")
    },
    resolver: {
      assetExts: assetExts.filter(ext => ext !== "svg"),
      sourceExts: [...sourceExts, "svg"]
    }
  };
})();

I Had the same problem that made because I did this in Startup.cs class and ConfigureServices method:

But you have to write your Interface in the first and your Class in the second

The easiest way to achieve is by applying width to view.

width: '80%'

As you are probably aware, ints are stored internally in binary. Typically an int contains 32 bits, but in some environments might contain 16 or 64 bits (or even a different number, usually but not necessarily a power of two).

But for this example, let's look at 4-bit integers. Tiny, but useful for illustration purposes.

Since there are four bits in such an integer, it can assume one of 16 values; 16 is two to the fourth power, or 2 times 2 times 2 times 2. What are those values? The answer depends on whether this integer is a signed int or an unsigned int. With an unsigned int, the value is never negative; there is no sign associated with the value. Here are the 16 possible values of a four-bit unsigned int:

bits  value
0000    0
0001    1
0010    2
0011    3
0100    4
0101    5
0110    6
0111    7
1000    8
1001    9
1010   10
1011   11
1100   12
1101   13
1110   14
1111   15

... and Here are the 16 possible values of a four-bit signed int:

bits  value
0000    0
0001    1
0010    2
0011    3
0100    4
0101    5
0110    6
0111    7
1000   -8
1001   -7
1010   -6
1011   -5
1100   -4
1101   -3
1110   -2
1111   -1

As you can see, for signed ints the most significant bit is 1 if and only if the number is negative. That is why, for signed ints, this bit is known as the "sign bit".

List<string> myList = new List<string>();
IEnumerable<string> myEnumerable = myList;
List<string> listAgain = myEnumerable.ToList();

Try this:

<img v-bind:src="'/media/avatars/' + joke.avatar" /> 

Don't forget single quote around your path string. also in your data check you have correctly defined image variable.

joke: {
  avatar: 'image.jpg'
}

A working demo here: http://jsbin.com/pivecunode/1/edit?html,js,output

The answers provided by Bohzo and Brabster will obviously work, but you could also just use:

rs3.getInt(1);

to get the value in the first, and in your case, only column.

I had an array of strings and needed an array of the same length of booleans initiated to True. This is what I did

strs = ["Hi","Bye"] 
bools = [ True for s in strs ]

Html:

<div id="wrap">
  <div id="main" class="container clear-top">
    <p>Your content here</p>
  </div>
</div>
<footer class="footer"></footer>

CSS:

html, body {
  height: 100%;
}

#wrap {
  min-height: 100%;
}

#main {
  overflow:auto;
  padding-bottom:150px; /* this needs to be bigger than footer height*/
}

.footer {
  position: relative;
  margin-top: -150px; /* negative value of footer height */
  height: 150px;
  clear:both;
  padding-top:20px;
} 

Are you using C# 3.0? You can use object initializers like so:

static MyStruct[] myArray = 
            new MyStruct[]{
                new MyStruct() { id = 1, label = "1" },
                new MyStruct() { id = 2, label = "2" },
                new MyStruct() { id = 3, label = "3" }
            };

Most proposed answers don't take into account a time-out interval, which is very important to prevent a possible deadlock. Next is my sample code. (Note that I'm primarily a Win32 developer, and that's how I'd do it there.)

//'arrRunningThreads' = List<Thread>

//Wait for all threads
const int knmsMaxWait = 3 * 1000;           //3 sec timeout
int nmsBeginTicks = Environment.TickCount;
foreach(Thread thrd in arrRunningThreads)
{
    //See time left
    int nmsElapsed = Environment.TickCount - nmsBeginTicks;
    int nmsRemain = knmsMaxWait - nmsElapsed;
    if(nmsRemain < 0)
        nmsRemain = 0;

    //Then wait for thread to exit
    if(!thrd.Join(nmsRemain))
    {
        //It didn't exit in time, terminate it
        thrd.Abort();

        //Issue a debugger warning
        Debug.Assert(false, "Terminated thread");
    }
}

This was just fixed with 2018-09-15 (3.25.0)

Enhancements the ALTER TABLE command:

• Add support for renaming columns within a table using ALTER TABLE table RENAME COLUMN oldname TO newname.
• Fix table rename feature so that it also updates references to the renamed table in triggers and views.

You can find the new syntax documented under ALTER TABLE

The RENAME COLUMN TO syntax changes the column-name of table table-name into new-column-name. The column name is changed both within the table definition itself and also within all indexes, triggers, and views that reference the column. If the column name change would result in a semantic ambiguity in a trigger or view, then the RENAME COLUMN fails with an error and no changes are applied.

^{Image source: https://www.sqlite.org/images/syntax/alter-table-stmt.gif}

Example:

CREATE TABLE tab AS SELECT 1 AS c;

SELECT * FROM tab;

ALTER TABLE tab RENAME COLUMN c to c_new;

SELECT * FROM tab;

Android Support

As of writing, Android's API 27 is using SQLite package version 3.19.

Based on the current version that Android is using and that this update is coming in version 3.25.0 of SQLite, I would say you have bit of a wait (approximately API 33) before support for this is added to Android.

And, even then, if you need to support any versions older than the API 33, you will not be able to use this.

I'd say it depends on what you need it for:

1. If you need it just to get 3 columns layout, I'd suggest to do it with float.

2. If you need it for menu, you can use inline-block. For the whitespace problem, you can use few tricks as described by Chris Coyier here http://css-tricks.com/fighting-the-space-between-inline-block-elements/.

3. If you need to make a multiple choice option, which the width needs to spread evenly inside a specified box, then I'd prefer display: table. This will not work correctly in some browsers, so it depends on your browser support.

Lastly, what might be the best method is using flexbox. The spec for this has changed few times, so it's not stable just yet. But once it has been finalized, this will be the best method I reckon.

You can add a span to your html and css .

Here's an example from my code ...

HTML ( JSX ):

<input type="radio" name="AMPM" id="radiostyle1" value="AM" checked={this.state.AMPM==="AM"} onChange={this.handleChange}/>  
<label for="radiostyle1"><span></span> am  </label>

<input type="radio" name="AMPM" id="radiostyle2" value="PM" checked={this.state.AMPM==="PM"} onChange={this.handleChange}/>
<label for="radiostyle2"><span></span> pm  </label>

CSS to make standard radio button vanish on screen and superimpose custom button image:

input[type="radio"] {  
    opacity:0;                                      
}

input[type="radio"] + label {
    font-size:1em;
    text-transform: uppercase;
    color: white ;  
    cursor: pointer;
    margin:auto 15px auto auto;                    
}

input[type="radio"] + label span {
    display:inline-block;
    width:30px;
    height:10px;
    margin:1px 0px 0 -30px;                       
    cursor:pointer;
    border-radius: 20%;
}


input[type="radio"] + label span {
    background-color: #FFFFFF 
}


input[type="radio"]:checked + label span{
     background-color: #660006;  
}

Another alternative solution:

cat  ~/.ssh/id_rsa.pub |  xsel -i -b

From man xsel :

-i, --input

read standard input into the selection.

-b, --clipboard

operate on the CLIPBOARD selection.

If you can use some dynamic query, you can use LEN . It will give false on both empty and null string. By this way you can implement the option parameter.

ALTER PROCEDURE [dbo].[psProducts] 
(@SearchType varchar(50))
AS
BEGIN
    SET NOCOUNT ON;

DECLARE @Query nvarchar(max) = N'
    SELECT 
        P.[ProductId],
        P.[ProductName],
        P.[ProductPrice],
        P.[Type]
    FROM [Product] P'
    -- if @Searchtype is not null then use the where clause
    SET @Query = CASE WHEN LEN(@SearchType) > 0 THEN @Query + ' WHERE p.[Type] = ' + ''''+ @SearchType + '''' ELSE @Query END   

    EXECUTE sp_executesql @Query
    PRINT @Query
END

I had the same problem. Using 'sudo python3 -m pip install selenium' may work.

Use set -e

#!/bin/bash

set -e

/bin/command-that-fails
/bin/command-that-fails2

The script will terminate after the first line that fails (returns nonzero exit code). In this case, command-that-fails2 will not run.

If you were to check the return status of every single command, your script would look like this:

#!/bin/bash

# I'm assuming you're using make

cd /project-dir
make
if [[ $? -ne 0 ]] ; then
    exit 1
fi

cd /project-dir2
make
if [[ $? -ne 0 ]] ; then
    exit 1
fi

With set -e it would look like:

#!/bin/bash

set -e

cd /project-dir
make

cd /project-dir2
make

Any command that fails will cause the entire script to fail and return an exit status you can check with $?. If your script is very long or you're building a lot of stuff it's going to get pretty ugly if you add return status checks everywhere.

Either:

1. with row.name inside the apply(..., axis=1) call:

df = pandas.DataFrame([[1,2,3],[4,5,6]], columns=['a','b','c'], index=['x','y'])

   a  b  c
x  1  2  3
y  4  5  6

df.apply(lambda row: row.name, axis=1)

x    x
y    y

2. with iterrows() (slower)

DataFrame.iterrows() allows you to iterate over rows, and access their index:

for idx, row in df.iterrows():
    ...

You don't have to cram multiple operations into one stream/lambda. Consider separating them into 2 statements (using static import of toList()):

entryList.forEach(e->e.setTempId(tempId));

List<Entry> updatedEntries = entryList.stream()

Just use this js file. (I mentioned 2 examples with different js files. hope the second one is what you need) You can simply change the scroll amount, speed etc by changing the parameters.

Here's a Demo

You can also try this. Here's a demo

GZip is simply deflate plus a checksum and header/footer. Deflate is faster, though, as I learned the hard way.

Easiest way to clear/reset the text field on click is to clear/reset the scope

<input type="text" class="form-control" ng-model="searchAll" ng-click="clearfunction(this)"/>

In Controller

$scope.clearfunction=function(event){
   event.searchAll=null;
}

Also you can use 'os.popen'. Example:

import os

command = os.popen('ls -al')
print(command.read())
print(command.close())

Output:

total 16
drwxr-xr-x 2 root root 4096 ago 13 21:53 .
drwxr-xr-x 4 root root 4096 ago 13 01:50 ..
-rw-r--r-- 1 root root 1278 ago 13 21:12 bot.py
-rw-r--r-- 1 root root   77 ago 13 21:53 test.py

None

take example if we want to compare "a" and "b", i.e ("a" == this)

1. negative int if a < b
2. if a == b
3. Positive int if a > b

This will also restore the staging directory:

git stash apply --index

String pooling

String pooling (sometimes also called as string canonicalisation) is a process of replacing several String objects with equal value but different identity with a single shared String object. You can achieve this goal by keeping your own Map (with possibly soft or weak references depending on your requirements) and using map values as canonicalised values. Or you can use String.intern() method which is provided to you by JDK.

At times of Java 6 using String.intern() was forbidden by many standards due to a high possibility to get an OutOfMemoryException if pooling went out of control. Oracle Java 7 implementation of string pooling was changed considerably. You can look for details in http://bugs.sun.com/view_bug.do?bug_id=6962931 and http://bugs.sun.com/view_bug.do?bug_id=6962930.

String.intern() in Java 6

In those good old days all interned strings were stored in the PermGen – the fixed size part of heap mainly used for storing loaded classes and string pool. Besides explicitly interned strings, PermGen string pool also contained all literal strings earlier used in your program (the important word here is used – if a class or method was never loaded/called, any constants defined in it will not be loaded).

The biggest issue with such string pool in Java 6 was its location – the PermGen. PermGen has a fixed size and can not be expanded at runtime. You can set it using -XX:MaxPermSize=96m option. As far as I know, the default PermGen size varies between 32M and 96M depending on the platform. You can increase its size, but its size will still be fixed. Such limitation required very careful usage of String.intern – you’d better not intern any uncontrolled user input using this method. That’s why string pooling at times of Java 6 was mostly implemented in the manually managed maps.

String.intern() in Java 7

Oracle engineers made an extremely important change to the string pooling logic in Java 7 – the string pool was relocated to the heap. It means that you are no longer limited by a separate fixed size memory area. All strings are now located in the heap, as most of other ordinary objects, which allows you to manage only the heap size while tuning your application. Technically, this alone could be a sufficient reason to reconsider using String.intern() in your Java 7 programs. But there are other reasons.

String pool values are garbage collected

Yes, all strings in the JVM string pool are eligible for garbage collection if there are no references to them from your program roots. It applies to all discussed versions of Java. It means that if your interned string went out of scope and there are no other references to it – it will be garbage collected from the JVM string pool.

Being eligible for garbage collection and residing in the heap, a JVM string pool seems to be a right place for all your strings, isn’t it? In theory it is true – non-used strings will be garbage collected from the pool, used strings will allow you to save memory in case then you get an equal string from the input. Seems to be a perfect memory saving strategy? Nearly so. You must know how the string pool is implemented before making any decisions.

First of all you should fix modal HTML structure. Now it's not correct, you don't need class .hide:

<div id="edit-modal" class="modal fade" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
    <div class="modal-dialog">
        <div class="modal-content">
            <div class="modal-header">
                <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
                <h4 class="modal-title" id="myModalLabel">Modal title</h4>
            </div>
            <div class="modal-body edit-content">
                ...
            </div>
            <div class="modal-footer">
                <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
                <button type="button" class="btn btn-primary">Save changes</button>
            </div>
        </div>
    </div>
</div>

Then links should point to this modal via data-target attribute:

<a href="#myModal" data-toggle="modal" id="1" data-target="#edit-modal">Edit 1</a>

Finally Js part becomes very simple:

    $('#edit-modal').on('show.bs.modal', function(e) {

        var $modal = $(this),
            esseyId = e.relatedTarget.id;

        $.ajax({
            cache: false,
            type: 'POST',
            url: 'backend.php',
            data: 'EID=' + essayId,
            success: function(data) {
                $modal.find('.edit-content').html(data);
            }
        });
    })

My tests with git-2.0.0 today indicate that the --mirror option does not copy hooks, the config file, the description file, the info/exclude file, and at least in my test case a few refs (which I don't understand.) I would not call it a "functionally identical copy, interchangeable with the original."

-bash-3.2$ git --version
git version 2.0.0
-bash-3.2$ git clone --mirror /git/hooks
Cloning into bare repository 'hooks.git'...
done.

For what it's worth, you can reset to default the value of a config entry with npm config delete <key> (or npm config rm <key>, but the usage of npm config rm is not mentioned in npm help config).

Example:

# set registry value
npm config set registry "https://skimdb.npmjs.com/registry"
# revert change back to default
npm config delete registry

As @user786653 suggested, use the xxd(1) program:

xxd -r -p input.txt output.bin

Gotta throw this one out there. If you convert the date using the 112 style (yyyymmdd) to a number you can use a calculation like this...

(yyyyMMdd - yyyyMMdd) / 10000 = difference in full years

declare @as_of datetime, @bday datetime;
select @as_of = '2009/10/15', @bday = '1980/4/20'

select 
    Convert(Char(8),@as_of,112),
    Convert(Char(8),@bday,112),
    0 + Convert(Char(8),@as_of,112) - Convert(Char(8),@bday,112), 
    (0 + Convert(Char(8),@as_of,112) - Convert(Char(8),@bday,112)) / 10000

output

20091015    19800420    290595  29

Here's something you can try without an order by but I think it requires that each row is unique. N is the number of rows you want, L is the number of rows in the table.

select * from tbl_name except select top L-N * from tbl_name

As noted before, which rows are returned is undefined.

EDIT: this is actually dog slow. Of no value really.

I think you'll get what you want with the -maxdepth 1 option, based on your current command structure. If not, you can try looking at the man page for find.

Relevant entry (for convenience's sake):

-maxdepth levels
          Descend at most levels (a non-negative integer) levels of direc-
          tories below the command line arguments.   `-maxdepth  0'  means
          only  apply the tests and actions to the command line arguments.

Your options basically are:

# Do NOT show hidden files (beginning with ".", i.e., .*):
find DirsRoot/* -maxdepth 0 -type f

Or:

#  DO show hidden files:
find DirsRoot/ -maxdepth 1 -type f

For those of you who are using MacOS and like me perhaps have been circling the internet as to why some R packages do not install here is a possible help.

If you get a non-zero exit status first check to ensure all dependencies are installed as well. Read through the messaging. If that is checked off, then look for indications such as gfortran: No such a file or directory. That might be due to Apple OS compiler issues that some packages will not install unless you use their binary version. Look for binary zip file in the package cran.r-project.org page, download it and use the following command to get the package installed:

install.packages("/PATH/zip file ", repos = NULL, type="source")

Visual Studio 2017 version 15.8 made it possible to use the PackageReferencesyntax to reference NuGet packages in Visual Studio Extensibility (VSIX) projects. This makes it much simpler to reason about NuGet packages and opens the door for having a complete meta package containing the entire VSSDK.

Installing below NuGet package will solve the EmbedInteropTypes Issue.

Install-Package Microsoft.VisualStudio.SDK.EmbedInteropTypes

You can handle CTRL+C by catching the KeyboardInterrupt exception. You can implement any clean-up code in the exception handler.

This worked for me fine:

File 1:

    <html>
    <head></head>
    <body>
        <a href="#" onclick="window.open('file:///D:/Examples/file2.html'); return false">CLICK ME</a>
    </body>
    <footer></footer>
    </html>

File 2:

    <html>
        ...
    </html>

This method works regardless of whether or not the 2 files are in the same directory, BUT both files must be local.

For obvious security reasons, if File 1 is located on a remote server you absolutely cannot open a file on some client's host computer and trying to do so will open a blank target.

PHP array_walk() function is specifically for altering array.

Try this:

array_walk ( $data, function (&$key) { 
    $key["transaction_date"] = date('d/m/Y',$key["transaction_date"]); 
});

You use 'git pull' to keep your branches separate. I will use the actual repository and branch names to help since 'lbranch' and 'rbranch' are tough to decipher.

Let's use:

git init
git pull [email protected]:myteam/tlc daves_branch:refs/remotes/origin/daves_branch

You may try with below query :

INSERT INTO errortable (dateupdated,table1id)
VALUES (to_date(to_char(sysdate,'dd/mon/yyyy hh24:mi:ss'), 'dd/mm/yyyy hh24:mi:ss' ),1083 );

To view the result of it:

SELECT to_char(hire_dateupdated, 'dd/mm/yyyy hh24:mi:ss') 
FROM errortable 
    WHERE table1id = 1083;

This probably works for a lot of things but it's not enough for Maven and certainly not for the maven compiler plugin.

Check Mike's answer to his own question here: stackoverflow question 24705877

This solved the issue for me both command line AND within eclipse.

Also, @LinGao answer to stackoverflow question 2503658 and the use of the $JAVACMD variable might help but I haven't tested it myself.

NGINX supports WebSockets by allowing a tunnel to be setup between a client and a backend server. In order for NGINX to send the Upgrade request from the client to the backend server, Upgrade and Connection headers must be set explicitly. For example:

# WebSocket proxying
map $http_upgrade $connection_upgrade {
    default         upgrade;
    ''              close;
}


server {
    listen 80;

    # The host name to respond to
    server_name cdn.domain.com;

    location / {
        # Backend nodejs server
        proxy_pass          http://127.0.0.1:8080;
        proxy_http_version  1.1;
        proxy_set_header    Upgrade     $http_upgrade;
        proxy_set_header    Connection  $connection_upgrade;
    }
}

Could it be that you have an error in your CSS file? A parenthesis left unclosed, a missing semicolon etc?

You can use the function last_insert_rowid():

The last_insert_rowid() function returns the ROWID of the last row insert from the database connection which invoked the function. The last_insert_rowid() SQL function is a wrapper around the sqlite3_last_insert_rowid() C/C++ interface function.

int x[] = { 10, 30, 15, 69, 52, 89, 5 };
    int max, temp = 0, index = 0;
    for (int i = 0; i < x.length; i++) {
        int counter = 0;
        max = x[i];
        for (int j = i + 1; j < x.length; j++) {

            if (x[j] > max) {
                max = x[j];
                index = j;
                counter++;
            }

        }
        if (counter > 0) {
            temp = x[index];
            x[index] = x[i];
            x[i] = temp;
        }
    }
    for (int i = 0; i < x.length; i++) {
        System.out.println(x[i]);
    }

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

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

Add some label and buttons.

Initialize the value in constructor and call it from anywhere.

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

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

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

// Calling

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

If you just do eval $cmd when we do cmd="ls -l" (interactively and in a script) we get the desired result. In your case, you have a pipe with a grep without a pattern, so the grep part will fail with an error message. Just $cmd will generate a "command not found" (or some such) message. So try use eval and use a finished command, not one that generates an error message.

I use printf, is shorter as it doesn't need flags to do the work:

printf "\rMy static $myvars composed text"

I guess the problem is that you need to start a separate thread for each connection and call serverSocket.accept() in a loop to accept more than one connection.

It is not a problem to have more than one connection on the same port.

• \r = CR (Carriage Return) → Used as a new line character in Mac OS before X

• \r\n = CR + LF → Used as a new line character in Windows

If I have to do this, I will simply create a schema sql of current db, then drop & create db, then load db with schema sql.

Below are the steps involved:

1) Create Schema dump of database (--schema-only)

pg_dump mydb -s > schema.sql

2) Drop database

drop database mydb;

3) Create Database

create database mydb;

4) Import Schema

psql mydb < schema.sql

I wanted to use JavaScript to change a form's action, so I could have different submit inputs within the same form linking to different pages.

I also had the added complication of using Apache rewrite to change example.com/page-name into example.com/index.pl?page=page-name. I found that changing the form's action caused example.com/index.pl (with no page parameter) to be rendered, even though the expected URL (example.com/page-name) was displayed in the address bar.

To get around this, I used JavaScript to insert a hidden field to set the page parameter. I still changed the form's action, just so the address bar displayed the correct URL.

function setAction (element, page)
{
  if(checkCondition(page))
  {
    /* Insert a hidden input into the form to set the page as a parameter.
     */
    var input = document.createElement("input");
    input.setAttribute("type","hidden");
    input.setAttribute("name","page");
    input.setAttribute("value",page);
    element.form.appendChild(input);

    /* Change the form's action. This doesn't chage which page is displayed,
     * it just make the URL look right.
     */
    element.form.action = '/' + page;
    element.form.submit();
  }
}

In the form:

<input type="submit" onclick='setAction(this,"my-page")' value="Click Me!" />

Here are my Apache rewrite rules:

RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} !-f
RewriteRule ^/(.*)$ %{DOCUMENT_ROOT}/index.pl?page=$1&%{QUERY_STRING}

I'd be interested in any explanation as to why just setting the action didn't work.

I had a similar issue last week. It was easy to fix in my IDE (PyCharm).

Here was my fix:

Starting from PyCharm menu bar: File -> Settings... -> Editor -> File Encodings, then set: "IDE Encoding", "Project Encoding" and "Default encoding for properties files" ALL to UTF-8 and she now works like a charm.

Hope this helps!

My application was hanging on startup when I used Peter Stulinski & Dave Gordon's code samples with EF 6.0. I changed:

var roleManager = new RoleManager<Microsoft.AspNet.Identity.EntityFramework.IdentityRole>(new RoleStore<IdentityRole>(new ApplicationDbContext()));

to

var roleManager = new RoleManager<Microsoft.AspNet.Identity.EntityFramework.IdentityRole>(new RoleStore<IdentityRole>(**context**));

Which makes sense when in the seed method you don't want instantiate another instance of the ApplicationDBContext. This might have been compounded by the fact that I had Database.SetInitializer<ApplicationDbContext>(new ApplicationDbInitializer()); in the constructor of ApplicationDbContext

mysql 5.4 provides a native split function:

SPLIT_STR(<column>, '<delimiter>', <index>)

One possibility you can try is to create 3 axes stacked one on top of the other with the 'Color' properties of the top two set to 'none' so that all the plots are visible. You would have to adjust the axes width, position, and x-axis limits so that the 3 y axes are side-by-side instead of on top of one another. You would also want to remove the x-axis tick marks and labels from 2 of the axes since they will lie on top of one another.

Here's a general implementation that computes the proper positions for the axes and offsets for the x-axis limits to keep the plots lined up properly:

%# Some sample data:
x = 0:20;
N = numel(x);
y1 = rand(1,N);
y2 = 5.*rand(1,N)+5;
y3 = 50.*rand(1,N)-50;

%# Some initial computations:
axesPosition = [110 40 200 200];  %# Axes position, in pixels
yWidth = 30;                      %# y axes spacing, in pixels
xLimit = [min(x) max(x)];         %# Range of x values
xOffset = -yWidth*diff(xLimit)/axesPosition(3);

%# Create the figure and axes:
figure('Units','pixels','Position',[200 200 330 260]);
h1 = axes('Units','pixels','Position',axesPosition,...
          'Color','w','XColor','k','YColor','r',...
          'XLim',xLimit,'YLim',[0 1],'NextPlot','add');
h2 = axes('Units','pixels','Position',axesPosition+yWidth.*[-1 0 1 0],...
          'Color','none','XColor','k','YColor','m',...
          'XLim',xLimit+[xOffset 0],'YLim',[0 10],...
          'XTick',[],'XTickLabel',[],'NextPlot','add');
h3 = axes('Units','pixels','Position',axesPosition+yWidth.*[-2 0 2 0],...
          'Color','none','XColor','k','YColor','b',...
          'XLim',xLimit+[2*xOffset 0],'YLim',[-50 50],...
          'XTick',[],'XTickLabel',[],'NextPlot','add');
xlabel(h1,'time');
ylabel(h3,'values');

%# Plot the data:
plot(h1,x,y1,'r');
plot(h2,x,y2,'m');
plot(h3,x,y3,'b');

and here's the resulting figure:

This is an old thread but just in case anyone does come across i think the most direct solution is to use CSS to make a traditional form look like an anchor-link.

@ben is correct you can use php and javascript to send a post with a link, but lets ask what the js does -- essentially it creates a form with style='display:none' sets an input/text line with value='something' and then submits it.

however you can skip all this by making a form. setting style='display:none' on the input/text lines (not the form itself as above) and then using CSS to make the button look like a normal link.

here is an example is i use:

in PHP Class,

public function styleButton($style,$text){
    $html_str = "<form id='view_form' action='".$_SERVER['REQUEST_URI']."' method='post' >";
    $html_str .= "<input style='display:none;' name='list_style' type='text' value='".$style."' >";
    $html_str .= "<input id='view_button' type='submit' value='".$text."' >";
    $html_str .= "</form>";
    return $html_str;
}

Then in the CSS id="view_form" set "display:inline;" and in the CSS id="view_button" set to something like: "background:none;border:none;color:#fff;cursor:pointer"

Lets assume your broadcastReceiver is defined like this:

private BroadcastReceiver broadcastReceiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {

        // your code

    }
};

If you are using LocalBroadcast in an Activity, then this is how you'll unregister:

LocalBroadcastManager.getInstance(this).unregisterReceiver(broadcastReceiver);

If you are using LocalBroadcast in a Fragment, then this is how you'll unregister:

LocalBroadcastManager.getInstance(getActivity()).unregisterReceiver(broadcastReceiver);

If you are using normal broadcast in an Activity, then this is how you'll unregister:

unregisterReceiver(broadcastReceiver);

If you are using normal broadcast in a Fragment, then this is how you'll unregister:

getActivity().unregisterReceiver(broadcastReceiver);

If the user is running El Capitan or higher, it will work in Chrome with

font-family: 'BlinkMacSystemFont';

try this

List<String> list = new ArrayList<String>();
list.add("List1");
list.add("List2");

String[] listArr = new String[list.size()];
listArr = list.toArray(listArr );

for(String s : listArr )
    System.out.println(s);

I guess you probably are running the preview of VS2013 Ultimate, because it is not present in my professional preview. But looking online I found that the feature is called Code Information Indicators or CodeLens, and can be located under

Tools ? Options ? Text Editor ? All Languages ? CodeLens

(for RC/final version)

or

Tools ? Options ? Text Editor ? All Languages ? Code Information Indicators

(for preview version)

That was according to this link. It seems to be pretty well hidden.

In Visual Studio 2013 RTM, you can also get to the CodeLens options by right clicking the indicators themselves in the editor:

documented in the Q&A section of the msdn CodeLens documentation

Just add the next nuget package to your project - Microsoft.CodeDom.Providers.DotNetCompilerPlatform.

Had the same problem.

You could try:

#!/bin/bash
### $1 == the first args to this script
### usage: script.sh /path/to/dir/

for f in `find . -maxdepth 1 -mindepth 1 -type d`; do
  cd "$f"
  <your job here>
done

or similar...

Explanation:

find . -maxdepth 1 -mindepth 1 -type d : Only find directories with a maximum recursive depth of 1 (only the subdirectories of $1) and minimum depth of 1 (excludes current folder .)

You should escape the quotes like this:

curl -i -X POST -d '{\"screencast\":{\"subject\":\"tools\"}}'  \
  http://localhost:3570/index.php/trainingServer/screencast.json

If your project is Maven-based, remember to set scope to provided for such dependencies as servlet-api, jsp-api. Otherwise, these jars will be exported to WEB-INF/lib and hence contaminate with those in Tomcat server. That causes painful problems.

<dependency>
  <groupId>javax.servlet</groupId>
  <artifactId>servlet-api</artifactId>
  <version>2.5</version>
  <scope>provided</scope>
</dependency>
<dependency>
  <groupId>javax.servlet.jsp</groupId>
  <artifactId>jsp-api</artifactId>
  <version>2.1</version>
  <scope>provided</scope>
</dependency>

Hamidreza's solution almost worked for me.

I noticed from experimentation that a simple tap usually has 2-5 action move events. Checking the time between action down and up was simpler and behaved more like what I expected.

private class CheckForClickTouchLister implements View.OnTouchListener {
    private final static long MAX_TOUCH_DURATION = 100;

    @Override
    public boolean onTouch(View v, MotionEvent event) {

        switch (event.getAction()) {

            case MotionEvent.ACTION_DOWN:
                m_DownTime = event.getEventTime(); //init time

                break;

            case MotionEvent.ACTION_UP:
                if(event.getEventTime() - m_DownTime <= MAX_TOUCH_DURATION)
                    //On click action

                break;

            default:
                break; //No-Op

        }
        return false;
    }

As Sohnee says, using System.Net.HttpWebRequest and set the Timeout property instead of using System.Net.WebClient.

You can't however set an infinite timeout value (it's not supported and attempting to do so will throw an ArgumentOutOfRangeException).

I'd recommend first performing a HEAD HTTP request and examining the Content-Length header value returned to determine the number of bytes in the file you're downloading and then setting the timeout value accordingly for subsequent GET request or simply specifying a very long timeout value that you would never expect to exceed.

This simple code worked for me

<!DOCTYPE html>_x000D_

Incase you need to use only select tag use Selectize Js. It has all options we require .Please Try It Demo using Selectize Js

Actually, I found out a really easy method for this, which is:

$('#fileinput').show().trigger('click').hide();   

This way, your file input field can have the css property display on none and still win the trade :)

select t1.Column as Price, t2.Column as Other_Price
from table1 as t1 INNER JOIN table2 as t2 
ON t1.Key = t2.Key 

like this ?

This way of specifying the encoding of a Python file comes from PEP 0263 - Defining Python Source Code Encodings.

It is also recognized by GNU Emacs (see Python Language Reference, 2.1.4 Encoding declarations), though I don't know if it was the first program to use that syntax.

<form action="portfolio.html">
 <button type="link" class="btn btn-primary btn-lg">View Work</button>
</form>

I just figured this out, and it links perfectly to another page without having my default link settings over ride my button classes! :)

I'm using this, https://github.com/miracle2k/django-tables.

<table>
<tr>
    {% for column in table.columns %}
    <th><a href="?sort={{ column.name_toggled }}">{{ column }}</a></th>
    {% endfor %}
</tr>
{% for row in table.rows %}
    <tr>
    {% for value in row %}
        <td>{{ value }}</td>
    {% endfor %}
    </tr>
{% endfor %}
</table>

TCLAP is a really nice lightweight design and easy to use: http://tclap.sourceforge.net/

Lucky discovery

if objFolderItem is Nothing when you call

objFolder.GetDetailsOf(objFolderItem, i)

the string returned is the name of the property, rather than its (undefined) value e.g. when i=3 it returns "Date modified"

Doing it for all 288 values of I makes it clear why most cause it to return blank for most filetypes e.g i=175 is "Horizontal resolution"

After playing around with a few things, I managed to figure this out myself.

First of all, this will convert a dataURI to a Blob:

function dataURItoBlob(dataURI) {
    // convert base64/URLEncoded data component to raw binary data held in a string
    var byteString;
    if (dataURI.split(',')[0].indexOf('base64') >= 0)
        byteString = atob(dataURI.split(',')[1]);
    else
        byteString = unescape(dataURI.split(',')[1]);

    // separate out the mime component
    var mimeString = dataURI.split(',')[0].split(':')[1].split(';')[0];

    // write the bytes of the string to a typed array
    var ia = new Uint8Array(byteString.length);
    for (var i = 0; i < byteString.length; i++) {
        ia[i] = byteString.charCodeAt(i);
    }

    return new Blob([ia], {type:mimeString});
}

From there, appending the data to a form such that it will be uploaded as a file is easy:

var dataURL = canvas.toDataURL('image/jpeg', 0.5);
var blob = dataURItoBlob(dataURL);
var fd = new FormData(document.forms[0]);
fd.append("canvasImage", blob);
