In case anybody is looking for methods to convert from/to C# and SQL Server formats, here goes a simple implementation:

private readonly string[] SqlServerTypes = { "bigint", "binary", "bit",  "char", "date",     "datetime", "datetime2", "datetimeoffset", "decimal", "filestream", "float",  "geography",                              "geometry",                              "hierarchyid",                              "image",  "int", "money",   "nchar",  "ntext",  "numeric", "nvarchar", "real",   "rowversion", "smalldatetime", "smallint", "smallmoney", "sql_variant", "text",   "time",     "timestamp", "tinyint", "uniqueidentifier", "varbinary", "varchar", "xml" };
private readonly string[] CSharpTypes    = { "long",   "byte[]", "bool", "char", "DateTime", "DateTime", "DateTime",  "DateTimeOffset", "decimal", "byte[]",     "double", "Microsoft.SqlServer.Types.SqlGeography", "Microsoft.SqlServer.Types.SqlGeometry", "Microsoft.SqlServer.Types.SqlHierarchyId", "byte[]", "int", "decimal", "string", "string", "decimal", "string",   "Single", "byte[]",     "DateTime",      "short",    "decimal",    "object",      "string", "TimeSpan", "byte[]",    "byte",    "Guid",             "byte[]",    "string",  "string" };

public string ConvertSqlServerFormatToCSharp(string typeName)
{
    var index = Array.IndexOf(SqlServerTypes, typeName);

    return index > -1
        ? CSharpTypes[index]
        : "object";
}

public string ConvertCSharpFormatToSqlServer(string typeName)
{
    var index = Array.IndexOf(CSharpTypes, typeName);

    return index > -1
        ? SqlServerTypes[index]
        : null;
}

Edit: fixed typo

First of all, I recommend writing the item you want to render multiple times (in your case list of fields) as a separate component:

function Field() {
    return (
        <View>
            <View>
                <TextInput />
            </View>
            <View>
                <TextInput />
            </View>
            <View>
                <TextInput />
            </View>
        </View>
    );
}

Then, in your case, when rendering based on some number and not a list, I'd move the for loop outside of the render method for a more readable code:

renderFields() {
    const noGuest = this.state.guest;
    const fields = [];
    for (let i=0; i < noGuest; i++) {
        // Try avoiding the use of index as a key, it has to be unique!
        fields.push(
            <Field key={"guest_"+i} />
        );
    }
    return fields;
}

render () {
    return (
        <View>
            <View>
                <View><Text>No</Text></View>
                <View><Text>Name</Text></View>
                <View><Text>Preference</Text></View>
            </View>
            {this.renderFields()}
        </View>;
    )
}

However, there are many more ways to render looped content in react native. Most of the ways are covered in this article, so please check it out if you're interested in more details! The examples in article are from React, but everything applies to React Native as well!

With the constructor:

// create a vector with 20 integer elements
std::vector<int> arr(20);

for(int x = 0; x < 20; ++x)
   arr[x] = x;

I have released Formic which implements multiple includes in a similar way to Apache Ant's FileSet and Globs.

The search can be implemented:

import formic
patterns = ["*.txt", "*.markdown", "*.mdown"]
fileset = formic.FileSet(directory=projectDir, include=patterns)
for file_name in fileset.qualified_files():
    # Do something with file_name

Because the full Ant glob is implemented, you can include different directories with each pattern, so you could choose only those .txt files in one subdirectory, and the .markdown in another, for example:

patterns = [ "/unformatted/**/*.txt", "/formatted/**/*.mdown" ]

I hope this helps.

Note that you may need to do something like ./gradlew <module_directory>:<module_name>:dependencies if the module has extra directory before reach its build.gradle. When in doubt, do ./gradlew tasks --all to check the name.

I want to update this question with a screenshot of a recent Android Studio. It took a bit of poking around to find where to install new system images.

You get to the SDK Manager through one of two paths. Option 1. Tools > Android > SDK Manager Option 2. Android Studio > Preferences > Appearance & Behavior > System Settings > Android SDK (This is for Mac; adapt for others.)

In the pane "SDK Platforms," check the "Show Packages" box to see the system images.

Select the ones you want, click "Apply" and voilà!

You Can Use

string txt = "                   i am a string                                    ";
txt = txt.TrimStart().TrimEnd();

Output is "i am a string"

I was able to use the workspace setting that other people on this page have been asking for.

In Preferences, ?+P, search for python.pythonPath in the search bar.

You should see something like:

// Path to Python, you can use a custom version of Python by modifying this setting to include the full path.
"python.pythonPath": "python"

Then click on the WORKSPACE SETTINGS tab on the right side of the window. This will make it so the setting is only applicable to the workspace you're in.

Afterwards, click on the pencil icon next to "python.pythonPath". This should copy the setting over the workspace settings.

Change the value to something like:

"python.pythonPath": "${workspaceFolder}/venv"

Most of the solutions are directly using grep command to find the class. However, it would not give you the package name of the class. Also if the jar is compressed, grep will not work.

This solution is using jar command to list the contents of the file and grep the class you are looking for.

It will print out the class with package name and also the jar file name.

find . -type f -name '*.jar' -print0 |  xargs -0 -I '{}' sh -c 'jar tf {} | grep Hello.class &&  echo {}'

You can also search with your package name like below:

find . -type f -name '*.jar' -print0 |  xargs -0 -I '{}' sh -c 'jar tf {} | grep com/mypackage/Hello.class &&  echo {}'

this should work in T-SQL

ALTER TABLE Countries  ADD
HasPhotoInReadyStorage  bit,  
HasPhotoInWorkStorage  bit,  
HasPhotoInMaterialStorage bit,  
HasText  bit GO

http://msdn.microsoft.com/en-us/library/ms190273(SQL.90).aspx

This should work:

String s = "123foo";
Character.isDigit(s.charAt(0));

You can use:

<input (input)="saverange()>

Here's some code for that purpose, with swedish holidays but you can adapt what holidays to count. Note that I added a limit you might want to remove, but it was for a web-based system and I didnt want anyone to enter some huge date to hog the process

This is an issue with the jdbc Driver version. I had this issue when I was using mysql-connector-java-commercial-5.0.3-bin.jar but when I changed to a later driver version mysql-connector-java-5.1.22.jar, the issue was fixed.

The ones I can think of are

Existential types

def foo(l: List[Option[_]]) = ...

Higher kinded type parameters

case class A[K[_],T](a: K[T])

Ignored variables

val _ = 5

Ignored parameters

List(1, 2, 3) foreach { _ => println("Hi") }

Ignored names of self types

trait MySeq { _: Seq[_] => }

Wildcard patterns

Some(5) match { case Some(_) => println("Yes") }

Wildcard patterns in interpolations

"abc" match { case s"a$_c" => }

Sequence wildcard in patterns

C(1, 2, 3) match { case C(vs @ _*) => vs.foreach(f(_)) }

Wildcard imports

import java.util._

Hiding imports

import java.util.{ArrayList => _, _}

Joining letters to operators

def bang_!(x: Int) = 5

Assignment operators

def foo_=(x: Int) { ... }

Placeholder syntax

List(1, 2, 3) map (_ + 2)

Method values

List(1, 2, 3) foreach println _

Converting call-by-name parameters to functions

def toFunction(callByName: => Int): () => Int = callByName _

Default initializer

var x: String = _   // unloved syntax may be eliminated

There may be others I have forgotten!

Example showing why foo(_) and foo _ are different:

This example comes from 0__:

trait PlaceholderExample {
  def process[A](f: A => Unit)

  val set: Set[_ => Unit]

  set.foreach(process _) // Error 
  set.foreach(process(_)) // No Error
}

In the first case, process _ represents a method; Scala takes the polymorphic method and attempts to make it monomorphic by filling in the type parameter, but realizes that there is no type that can be filled in for A that will give the type (_ => Unit) => ? (Existential _ is not a type).

In the second case, process(_) is a lambda; when writing a lambda with no explicit argument type, Scala infers the type from the argument that foreach expects, and _ => Unit is a type (whereas just plain _ isn't), so it can be substituted and inferred.

This may well be the trickiest gotcha in Scala I have ever encountered.

Note that this example compiles in 2.13. Ignore it like it was assigned to underscore.

Adding on to Nick Craver's answer and also considering the point raised by rossisdead, if scenario exists like one has to append to an empty table, or before a certain row, I have done like this:

var arr = []; //array
if (your condition) {
  arr.push(row.id); //push row's id for eg: to the array
  idx = arr.sort().indexOf(row.id);

  if (idx === 0) {   
    if (arr.length === 1) {  //if array size is only 1 (currently pushed item)
        $("#tableID").append(row);
    }
    else {       //if array size more than 1, but index still 0, meaning inserted row must be the first row
       $("#tableID tr").eq(idx + 1).before(row);
    }   
  }          
  else {     //if index is greater than 0, meaning inserted row to be after specified index row
      $("#tableID tr").eq(idx).after(row);
  }    
}

Hope it helps someone.

you can try this.

data_you_need=pd.DataFrame()
for infile in glob.glob("*.xlsx"):
    data = pandas.read_excel(infile)
    data_you_need=data_you_need.append(data,ignore_index=True)

I hope it can help.

Windows + Apache 2.4, for example:

1. uncomment ssl_module in your httpd.conf file.

   LoadModule ssl_module modules/mod_ssl.so
   

2. listen 443 port just like 80 port in your httpd.conf file.

   Listen 80
   Listen 443
   

3. uncomment Include Virtual hosts in your httpd.conf file.

   # Virtual hosts
   Include conf/extra/httpd-vhosts.conf
   

4. add VirtualHost in your conf/extra/httpd-vhosts.conf

   <VirtualHost _default_:443>
       DocumentRoot "D:/www"  #your site directory path
       ServerName localhost
       #ServerAlias localhost.com localhost2.com
       SSLEngine on
       SSLCertificateFile "${SRVROOT}/conf/ssl/server.crt"
       SSLCertificateKeyFile "${SRVROOT}/conf/ssl/server.key"
       <Directory "D:/www">
           Options -Indexes +FollowSymLinks +ExecCGI
           AllowOverride All
           Require all granted
       </Directory>
   </VirtualHost>
   

only the port number 443 and SSL...... lines are different from normal http config.

save you config file and restart apache service. then you can visit https://localhost/

The web browser will warn you that it's unsafe at the first time, just choose go on.

ApplicationContext springContext =

WebApplicationContextUtils.getWebApplicationContext(ContextLoaderListener .getCurrentWebApplicationContext().getServletContext());

Bean bean = (Bean) springContext.getBean("beanName");

bean.method();

Use is.na

DF <- data.frame(x = c(1, 2, 3), y = c(0, 10, NA), z=c(NA, 33, 22))
DF[!is.na(DF$y),]

Just (temporarily) killed my Macbook with

killall -u pu -m .

where pu is my userid. Watch the dot at the end of the command.

Also try

pkill -u pu

or

ps -o pid -u pu | xargs kill -1

It works on either option tag or text field:

$("#idname option[value='option1']").remove();

When it is on server side, use web services - maybe RESTful with JSON.

• create a web service (for example with Tomcat)
• call its URL from JavaScript (for example with JQuery or dojo)

When Java code is in applet you can use JavaScript bridge. The bridge between the Java and JavaScript programming languages, known informally as LiveConnect, is implemented in Java plugin. Formerly Mozilla-specific LiveConnect functionality, such as the ability to call static Java methods, instantiate new Java objects and reference third-party packages from JavaScript, is now available in all browsers.

Below is example from documentation. Look at methodReturningString.

Java code:

public class MethodInvocation extends Applet {
    public void noArgMethod() { ... }
    public void someMethod(String arg) { ... }
    public void someMethod(int arg) { ... }
    public int  methodReturningInt() { return 5; }
    public String methodReturningString() { return "Hello"; }
    public OtherClass methodReturningObject() { return new OtherClass(); }
}

public class OtherClass {
    public void anotherMethod();
}

Web page and JavaScript code:

<applet id="app"
        archive="examples.jar"
        code="MethodInvocation" ...>
</applet>
<script language="javascript">
    app.noArgMethod();
    app.someMethod("Hello");
    app.someMethod(5);
    var five = app.methodReturningInt();
    var hello = app.methodReturningString();
    app.methodReturningObject().anotherMethod();
</script>

Comparable is for objects with a natural ordering. The object itself knows how it is to be ordered.
Comparator is for objects without a natural ordering or when you wish to use a different ordering.

These code lines can help you quickly enable log setting in your magento site.

INSERT INTO `core_config_data` (`config_id`, `scope`, `scope_id`, `path`, `value`) VALUES
('', 'default', 0, 'dev/log/active', '1'),
('', 'default', 0, 'dev/log/file', 'system.log'),
('', 'default', 0, 'dev/log/exception_file', 'exception.log');

Then you can see them inside the folder: /var/log under root installation.

clearfix should contain the floating elements but in your html you have added clearfix only after floating right that is your pull-right so you should do like this:

<div class="clearfix">
  <div id="sidebar">
    <ul>
      <li>A</li>
      <li>A</li>
      <li>C</li>
      <li>D</li>
      <li>E</li>
      <li>F</li>
      <li>...</li>
      <li>Z</li>
    </ul>
  </div>
  <div id="main">
    <div>
      <div class="pull-right">
        <a>RIGHT</a>
      </div>
    </div>
  <div>MOVED BELOW Z</div>
</div>

Happy to know you solved the problem by setting overflow properties. However this is also good idea to clear the float. Where you have floated your elements you could add overflow: hidden; as you have done in your main.

I added jstl jar in a library and added it to build path and deployment assembly but it dint worked. then i simply copied my jstl jar into lib folder inside webcontent, it worked. in eclipse lib folder in included to deployment assembly by default

Had a similar problem, where I had to set the form back to pristine, but also to untouched, since $invalid and $error were both used to show error messages. Only using setPristine() was not enough to clear the error messages.

I solved it by using setPristine() and setUntouched(). (See Angular's documentation: https://docs.angularjs.org/api/ng/type/ngModel.NgModelController)

So, in my controller, I used:

$scope.form.setPristine(); 
$scope.form.setUntouched();

These two functions reset the complete form to $pristine and back to $untouched, so that all error messages were cleared.

I would write :

var handleData = function (data) {
    alert(data);
    //do some stuff
}


function getData() {
    $.ajax({
        url : 'example.com',
        type: 'GET',
        success : handleData
    })
}

This Answer isnt limited to minikube!

Use a local registry:

docker run -d -p 5000:5000 --restart=always --name registry registry:2

Now tag your image properly:

docker tag ubuntu localhost:5000/ubuntu

Note that localhost should be changed to dns name of the machine running registry container.

Now push your image to local registry:

docker push localhost:5000/ubuntu

You should be able to pull it back:

docker pull localhost:5000/ubuntu

Now change your yaml file to use local registry.

Think about mounting volume at appropriate location to persist the images on registry.

update:

as Eli stated, you'll need to add the local registry as insecure in order to use http (may not apply when using localhost but does apply if using the local hostname)

Don't use http in production, make the effort for securing things up.

You could look into using BrowserStack: http://www.browserstack.com

While not free, it is rather cheap. It allows you to test against several iOS versions on both iPhone and iPad, along with Android, and various desktop browsers and OSs. It has proved quite invaluable to my workplace for doing just these sort of tests.

Have you tried .editorconfig? You can create this file in the root of your project and configure indentation for different file types. Your code will be automatically formatted. Here's the example:

# top-most EditorConfig file
root = true

# matches all files
[*]
indent_style = tab
indent_size = 4

# only json
[*.json]
indent_style = space
indent_size = 2

It's been correctly pointed out above that finding a given word in a sentence is not the same as finding the charsequence, and can be done as follows if you don't want to mess around with regular expressions.

boolean checkWordExistence(String word, String sentence) {
    if (sentence.contains(word)) {
        int start = sentence.indexOf(word);
        int end = start + word.length();

        boolean valid_left = ((start == 0) || (sentence.charAt(start - 1) == ' '));
        boolean valid_right = ((end == sentence.length()) || (sentence.charAt(end) == ' '));

        return valid_left && valid_right;
    }
    return false;
}

Output:

checkWordExistence("the", "the earth is our planet"); true

P.S Make sure you have filtered out any commas or full stops beforehand.

this is because str is pointing to a string literal means a constant string ...but you are trying to modify it by copying . Note : if it would have been an error due to memory allocation it would have been given segmentation fault at the run time .But this error is coming due to constant string modification or you can go through the below for more details abt bus error :

Bus errors are rare nowadays on x86 and occur when your processor cannot even attempt the memory access requested, typically:

• using a processor instruction with an address that does not satisfy its alignment requirements.

Segmentation faults occur when accessing memory which does not belong to your process, they are very common and are typically the result of:

• using a pointer to something that was deallocated.
• using an uninitialized hence bogus pointer.
• using a null pointer.
• overflowing a buffer.

To be more precise this is not manipulating the pointer itself that will cause issues, it's accessing the memory it points to (dereferencing).

Or you could use File.AppendAllLines(string, IEnumerable<string>)

File.AppendAllLines(@"C:\Path\file.txt", new[] { "my text content" });

<button onclick=location=URL>Refresh</button>

Small hack.

The python-espeak package is available in Debian, Ubuntu, Redhat, and other Linux distributions. It has recent updates, and works fine.

from espeak import espeak
espeak.synth("Hello world.")

Jonathan Leaders notes that it also works on Windows, and you can install the mbrola voices as well. See the espeak website at http://espeak.sourceforge.net

scanf("%2000s %2000[^\n]", a, b);

do wget -r -l0 www.oldsite.com

Then just find www.oldsite.com would reveal all urls, I believe.

Alternatively, just serve that custom not-found page on every 404 request! I.e. if someone used the wrong link, he would get the page telling that page wasn't found, and making some hints about site's content.

I find another solution:

<input type="text" class="disabled" name="test" value="test" />

Class "disabled" immitate disabled element by opacity:

<style type="text/css">
    input.disabled {
        opacity: 0.5;
    }
</style>

And then cancel the event if element is disabled and remove class:

$(document).on('click','input.disabled',function(event) {
    event.preventDefault();
    $(this).removeClass('disabled');
});

So if you are simply using the unsophisticated API, like I often am (I use it in ipython a lot), then this is simply

yscale('log')
plot(...)

Hope this helps someone looking for a simple answer! :).

Many answers already, but none of them perfect IMHO. Thanatos' answer leaves some extra characters per line and Sorpigal's answer requires the files to be sorted or pre-sorted, which may not be adequate in all circumstances.

I think the best way of getting the lines that are different and nothing else (no extra chars, no re-ordering) is a combination of diff, grep, and awk (or similar).

If the lines do not contain any "<", a short one-liner can be:

diff urls.txt* | grep "<" | sed 's/< //g'

but that will remove every instance of "< " (less than, space) from the lines, which is not always OK (e.g. source code). The safest option is to use awk:

diff urls.txt* | grep "<" | awk '{for (i=2; i<NF; i++) printf $i " "; print $NF}'

This one-liner diffs both files, then filters out the ed-style output of diff, then removes the trailing "<" that diff adds. This works even if the lines contains some "<" themselves.

I'll like to add to this post, that I was experienceing the same issue but in a PartialView.

And I needed to add

<script src="~/Scripts/jquery.validate.unobtrusive.min.js"></script>

To the partial view, even if already present in the _Layout view.

Just in case you are not sure the string starts with a word...

$input = ' Test me more ';
echo preg_replace('/(\s*)([^\s]*)(.*)/', '$2', $input); //Test

By the way, it's worth noting that some mobile devices, particularly Apple products like iPhone/iPad completely ignore headers like no-cache, no-store, Expires: 0, or whatever else you may try to force them to not re-use expired form pages.

This has caused us no end of headaches as we try to get the issue of a user's iPad say, being left asleep on a page they have reached through a form process, say step 2 of 3, and then the device totally ignores the store/cache directives, and as far as I can tell, simply takes what is a virtual snapshot of the page from its last state, that is, ignoring what it was told explicitly, and, not only that, taking a page that should not be stored, and storing it without actually checking it again, which leads to all kinds of strange Session issues, among other things.

I'm just adding this in case someone comes along and can't figure out why they are getting session errors with particularly iphones and ipads, which seem by far to be the worst offenders in this area.

I've done fairly extensive debugger testing with this issue, and this is my conclusion, the devices ignore these directives completely.

Even in regular use, I've found that some mobiles also totally fail to check for new versions via say, Expires: 0 then checking last modified dates to determine if it should get a new one.

It simply doesn't happen, so what I was forced to do was add query strings to the css/js files I needed to force updates on, which tricks the stupid mobile devices into thinking it's a file it does not have, like: my.css?v=1, then v=2 for a css/js update. This largely works.

User browsers also, by the way, if left to their defaults, as of 2016, as I continuously discover (we do a LOT of changes and updates to our site) also fail to check for last modified dates on such files, but the query string method fixes that issue. This is something I've noticed with clients and office people who tend to use basic normal user defaults on their browsers, and have no awareness of caching issues with css/js etc, almost invariably fail to get the new css/js on change, which means the defaults for their browsers, mostly MSIE / Firefox, are not doing what they are told to do, they ignore changes and ignore last modified dates and do not validate, even with Expires: 0 set explicitly.

This was a good thread with a lot of good technical information, but it's also important to note how bad the support for this stuff is in particularly mobile devices. Every few months I have to add more layers of protection against their failure to follow the header commands they receive, or to properly interpet those commands.

Is Powershell an option?

Start Powershell:

You can manage your VPN connections with the powershell commands above, and simply use the connection name to connect via rasdial.

The results of Get-VpnConnection can be a little verbose. This can be simplified with a simple Select-Object filter:

Get-VpnConnection | Select-Object -Property Name

For copy directory use following command

cp -r source    Destination

For example

cp -r  /home/hasan   /opt 

For copy file use command without -r

cp   /home/file    /home/hasan/

Not possible.

You can only store, simple values in SharedPrefences SharePreferences.Editor

What particularly about the class do you need to save?

Ahh an event listener and change the icon through setIcon() method:

createdMarker.on("dblclick", function(evt) {

        var myIcon = L.icon({
            iconUrl: 'res/marker-icon-red.png',
            shadowUrl: 'res/marker-shadow.png'
        });
        this.setIcon(myIcon);
});

Beautiful explanation given by bobf for Boolean values : True or False? A Quick Reference Guide

Truth tests for different values

                       Result of the expression when $var is:

Expression          | 1      | '0.0'  | a string | 0     | empty str | undef
--------------------+--------+--------+----------+-------+-----------+-------
if( $var )          | true   | true   | true     | false | false     | false
if( defined $var )  | true   | true   | true     | true  | true      | false
if( $var eq '' )    | false  | false  | false    | false | true      | true
if( $var == 0 )     | false  | true   | true     | true  | true      | true

For your particular example, I would just do this, since you obviously don't care about actually having the browser get the redirect anyway (by virtue of accepting the answer you have already accepted):

[AcceptVerbs(HttpVerbs.Get)]
public ActionResult Index() {
   // obviously these values might come from somewhere non-trivial
   return Index(2, "text");
}

[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Index(int someValue, string anotherValue) {
   // would probably do something non-trivial here with the param values
   return View();
}

That works easily and there is no funny business really going on - this allows you to maintain the fact that the second one really only accepts HTTP POST requests (except in this instance, which is under your control anyway) and you don't have to use TempData either, which is what the link you posted in your answer is suggesting.

I would love to know what is "wrong" with this, if there is anything. Obviously, if you want to really have sent to the browser a redirect, this isn't going to work, but then you should ask why you would be trying to convert that regardless, since it seems odd to me.

Hope that helps.

I agree with Justin, and the WhiteSpace CHAR can be referenced using ASCII codes here Character number 32 represents a white space, Therefore:

string.Empty.PadRight(totalLength, (char)32);

An alternative approach: Create all spaces manually within a custom method and call it:

private static string GetSpaces(int totalLength)
    {
        string result = string.Empty;
        for (int i = 0; i < totalLength; i++)
        {
            result += " ";
        }
        return result;
    }

And call it in your code to create white spaces: GetSpaces(14);

This is a full working example :

import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpPost; 
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.util.EntityUtils;

public void callWebService(String soapAction, String soapEnvBody)  throws IOException {
    // Create a StringEntity for the SOAP XML.
    String body ="<?xml version=\"1.0\" encoding=\"UTF-8\"?><SOAP-ENV:Envelope xmlns:SOAP-ENV=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:ns1=\"http://example.com/v1.0/Records\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:SOAP-ENC=\"http://schemas.xmlsoap.org/soap/encoding/\" SOAP-ENV:encodingStyle=\"http://schemas.xmlsoap.org/soap/encoding/\"><SOAP-ENV:Body>"+soapEnvBody+"</SOAP-ENV:Body></SOAP-ENV:Envelope>";
    StringEntity stringEntity = new StringEntity(body, "UTF-8");
    stringEntity.setChunked(true);

    // Request parameters and other properties.
    HttpPost httpPost = new HttpPost("http://example.com?soapservice");
    httpPost.setEntity(stringEntity);
    httpPost.addHeader("Accept", "text/xml");
    httpPost.addHeader("SOAPAction", soapAction);

    // Execute and get the response.
    HttpClient httpClient = new DefaultHttpClient();
    HttpResponse response = httpClient.execute(httpPost);
    HttpEntity entity = response.getEntity();

    String strResponse = null;
    if (entity != null) {
        strResponse = EntityUtils.toString(entity);
    }
}

I often need to run an X command on a server that is running many X servers, so the ps based answers do not work. Naturally, $DISPLAY has to be set appropriately. To check that that is valid, use xset q in some fragment like:

if ! xset q &>/dev/null; then
    echo "No X server at \$DISPLAY [$DISPLAY]" >&2
    exit 1
fi

EDIT

Some people find that xset can pause for a annoying amount of time before deciding that $DISPLAY is not pointing at a valid X server (often when tcp/ip is the transport). The fix of course is to use timeout to keep the pause amenable, 1 second say.

if ! timeout 1s xset q &>/dev/null; then
    ?

You're only getting the first line from the diamond operator <FILE> because you're evaluating it in scalar context:

$document = <FILE>; 

In list/array context, the diamond operator will return all the lines of the file.

@lines = <FILE>;
print @lines;

Match objects are always true, and None is returned if there is no match. Just test for trueness.

Code:

>>> st = 'bar'
>>> m = re.match(r"ba[r|z|d]",st)
>>> if m:
...     m.group(0)
...
'bar'

Output = bar

If you want search functionality

>>> st = "bar"
>>> m = re.search(r"ba[r|z|d]",st)
>>> if m is not None:
...     m.group(0)
...
'bar'

and if regexp not found than

>>> st = "hello"
>>> m = re.search(r"ba[r|z|d]",st)
>>> if m:
...     m.group(0)
... else:
...   print "no match"
...
no match

As @bukzor mentioned if st = foo bar than match will not work. So, its more appropriate to use re.search.

Some basics:

RTSP server can be used for dead source as well as for live source. RTSP protocols provides you commands (Like your VCR Remote), and functionality depends upon your implementation.

RTP is real time protocol used for transporting audio and video in real time. Transport used can be unicast, multicast or broadcast, depending upon transport address and port. Besides transporting RTP does lots of things for you like packetization, reordering, jitter control, QoS, support for Lip sync.....

In your case if you want broadcasting streaming server then you need both RTSP (for control) as well as RTP (broadcasting audio and video)

To start with you can go through sample code provided by live555

OFFICE 2013 INSTRUCTIONS:

(For Windows 7 (x64) | MS Office 32-Bit)

Option 1 | Check if ability already exists | 2 minutes

1. Open VB Editor
2. Tools -> Additional Controls
3. Select "Microsoft Monthview Control 6.0 (SP6)" (if applicable)
4. Use 'DatePicker' control for VBA Userform

Option 2 | The "Monthview" Control doesn't currently exist | 5 minutes

1. Close Excel
2. Download MSCOMCT2.cab (it's a cabinet file which extracts into two useful files)
3. Extract Both Files | the .inf file and the .ocx file
4. Install | right-click the .inf file | hit "Install"
5. Move .ocx file | Move from "C:\Windows\system32" to "C:\Windows\sysWOW64"
6. Run CMD | Start Menu -> Search -> "CMD.exe" | right-click the icon | Select "Run as administrator"
7. Register Active-X File | Type "regsvr32 c:\windows\sysWOW64\MSCOMCT2.ocx"
8. Open Excel | Open VB Editor
9. Activate Control | Tools->References | Select "Microsoft Windows Common Controls 2-6.0 (SP6)"
10. Userform Controls | Select any userform in VB project | Tools->Additional Controls
11. Select "Microsoft Monthview Control 6.0 (SP6)"
12. Use 'DatePicker' control for VBA UserForm

Okay, either of these two steps should work for you if you have Office 2013 (32-Bit) on Windows 7 (x64). Some of the steps may be different if you have a different combo of Windows 7 & Office 2013.

The "Monthview" control will be your fully fleshed out 'DatePicker'. It comes equipped with its own properties and image. It works very well. Good luck.

multi-map

This is really helpful if you want to create a multimap without resorting to the Google Guava library for its implementation of MultiMap.

For example, suppose you want to store a list of students who enrolled for a particular subject.

The normal solution for this using JDK library is:

Map<String,List<String>> studentListSubjectWise = new TreeMap<>();
List<String>lis = studentListSubjectWise.get("a");
if(lis == null) {
    lis = new ArrayList<>();
}
lis.add("John");

//continue....

Since it have some boilerplate code, people tend to use Guava Mutltimap.

Using Map.computeIfAbsent, we can write in a single line without guava Multimap as follows.

studentListSubjectWise.computeIfAbsent("a", (x -> new ArrayList<>())).add("John");

Stuart Marks & Brian Goetz did a good talk about this https://www.youtube.com/watch?v=9uTVXxJjuco

You want reorder(). Here is an example with dummy data

set.seed(42)
df <- data.frame(Category = sample(LETTERS), Count = rpois(26, 6))

require("ggplot2")

p1 <- ggplot(df, aes(x = Category, y = Count)) +
         geom_bar(stat = "identity")

p2 <- ggplot(df, aes(x = reorder(Category, -Count), y = Count)) +
         geom_bar(stat = "identity")

require("gridExtra")
grid.arrange(arrangeGrob(p1, p2))

Giving:

Use reorder(Category, Count) to have Category ordered from low-high.

Here is the example of one Object, For your case you have to use JSONArray.

public static final String JSON_STRING="{\"employee\":{\"name\":\"Sachin\",\"salary\":56000}}";  
try{  
   JSONObject emp=(new JSONObject(JSON_STRING)).getJSONObject("employee");  
   String empname=emp.getString("name");  
   int empsalary=emp.getInt("salary");  

   String str="Employee Name:"+empname+"\n"+"Employee Salary:"+empsalary;  
   textView1.setText(str);  

}catch (Exception e) {e.printStackTrace();}  
   //Do when JSON has problem.
}

I don't have time but tried to give an idea. If you still can't do it, then I will help.

#define DEBUG

#ifdef DEBUG
  #define PRINT print
#else
  #define PRINT(...) ((void)0) //strip out PRINT instructions from code
#endif 

void print(const char *fmt, ...) {

    va_list args;
    va_start(args, fmt);
    vsprintf(str, fmt, args);
        va_end(args);

        printf("%s\n", str);

}

int main() {
   PRINT("[%s %d, %d] Hello World", "March", 26, 2009);
   return 0;
}

If the compiler does not understand variadic macros, you can also strip out PRINT with either of the following:

#define PRINT //

or

#define PRINT if(0)print

The first comments out the PRINT instructions, the second prevents PRINT instruction because of a NULL if condition. If optimization is set, the compiler should strip out never executed instructions like: if(0) print("hello world"); or ((void)0);

I had this problem because of a trigger not working..Worked after I deleted the trigger.

JNZ is short for "Jump if not zero (ZF = 0)", and NOT "Jump if the ZF is set".

If it's any easier to remember, consider that JNZ and JNE (jump if not equal) are equivalent. Therefore, when you're doing cmp al, 47 and the content of AL is equal to 47, the ZF is set, ergo the jump (if Not Equal - JNE) should not be taken.

You could split things up, it would require more code but would work just the way you like it:

DateTime year = DateTime.Now.Year;
DateTime month = DateTime.Now.Month;
DateTime day = DateTime.Now.Day;

ect.

finally:

Console.WriteLine(year+month+day+etc.);

This is a very bold way of handling it though...

Console applications will exit when the main function has finished running. A "return" will achieve this.

    static void Main(string[] args)
    {
        while (true)
        {
            Console.WriteLine("I'm running!");
            return; //This will exit the console application's running thread
        }
    }

If you're returning an error code you can do it this way, which is accessible from functions outside of the initial thread:

    System.Environment.Exit(-1);

Just a simplification of the Tim's answer. The groovy way to do it is using a map, as already suggested, but then let's put the mandatory parameters also in the map. This will look like this:

def someMethod(def args) {
    println "MANDATORY1=${args.mandatory1}"
    println "MANDATORY2=${args.mandatory2}"
    println "OPTIONAL1=${args?.optional1}"
    println "OPTIONAL2=${args?.optional2}"
}

someMethod mandatory1:1, mandatory2:2, optional1:3

with the output:

MANDATORY1=1
MANDATORY2=2
OPTIONAL1=3
OPTIONAL2=null

This looks nicer and the advantage of this is that you can change the order of the parameters as you like.

This line looks suspicious:

invaders[i] = inv;

You're never incrementing i, so you keep assigning to invaders[0]. If this is just an error you made when reducing your code to the example, check how you calculate i in the real code; you could be exceeding the size of invaders.

If as your comment suggests, you're creating 55 invaders, then check that invaders has been initialised correctly to handle this number.

Encrypt:

openssl enc -in infile.txt -out encrypted.dat -e -aes256 -k symmetrickey

Decrypt:

openssl enc -in encrypted.dat -out outfile.txt -d -aes256 -k symmetrickey

For details, see the openssl(1) docs.

So this question has been answered but to me the code used is not simple enough or complete. To me this bit here is what I was looking for and possibly some other people will like this as well.

string dateString = "198101";

if (DateTime.TryParse(dateString, out DateTime Temp) == true)
{
     //do stuff
}

The output is stored in Temp and not needed afterwards, datestring is the input string to be tested.

Visual Studio reads NuGet.Config files from the solution root. Try moving it there instead of placing it in the same folder as the project.

In my case 'await' never finished because of exception while executing the request, e.g. server not responding, etc. Surround it with try..catch to identify what happened, it'll also complete your 'await' gracefully.

If you want implications, in some scenarios Google Chrome performance is horrible with hardware acceleration enabled. Oddly enough, changing the "trick" to -webkit-transform: rotateZ(360deg); worked just fine.

I don't believe we ever figured out why.

1. A static method can NOT access a Non-static method or variable.

2. public static void main(String[] args) is a static method, so can NOT access the Non-static public static int fxn(int y) method.

3. Try it this way...

   static int fxn(int y)

   public class Two {
   
   
       public static void main(String[] args) {
           int x = 0;
   
           System.out.println("x = " + x);
           x = fxn(x);
           System.out.println("x = " + x);
       }
   
       static int fxn(int y) {
           y = 5;
           return y;
       }
   

   }

I've experienced a problem with length of None, which leads to Internal Server Error: TypeError: object of type 'NoneType' has no len()

My workaround is just displaying 0 if object is None and calculate length of other types, like list in my case:

Easy solution for .Net Core WinForms / WPF / .Net Standard Class Library projects

step 1: Install System.Configuration.ConfigurationManager by Nuget Manager

step 2: Add a new App.Config file

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <appSettings>
    <add key="Bodrum" value="Yalikavak" />    
  </appSettings>
</configuration>

step3: Get the value

string value = ConfigurationManager.AppSettings.Get("Bodrum");
// value is Yalikavak

If you are calling it from a Class Library then add the App.Config file on your Main Project.

An important note about Hashtable vs Dictionary for high frequency systematic trading engineering: Thread Safety Issue

Hashtable is thread safe for use by multiple threads. Dictionary public static members are thread safe, but any instance members are not guaranteed to be so.

So Hashtable remains the 'standard' choice in this regard.

        minutes = '0%s' % minutes
    if seconds < 10:
        seconds = '0%s' % seconds
    return '%s:%s:%s' % (hours, minutes, seconds)

$("#employeeTable td").parent().remove();

This will remove all tr having td as child. i.e all rows except the header will be deleted.

Here's a rotation generator which doesn't need to make a warped copy of the input sequence ... may be useful if the input sequence is much larger than 7 items.

>>> def rotated_sequence(seq, start_index):
...     n = len(seq)
...     for i in xrange(n):
...         yield seq[(i + start_index) % n]
...
>>> s = 'su m tu w th f sa'.split()
>>> list(rotated_sequence(s, s.index('m')))
['m', 'tu', 'w', 'th', 'f', 'sa', 'su']
>>>

If your use case is that some backend code inserts a record, then the same code wants to retrieve the last insert id, without counting on any underlying data access library preset function to do this, then, as mentioned by others, you should just craft your SQL query using SEQ_MY_NAME.NEXTVAL for the column you want (usually the primary key), then just run statement SELECT SEQ_MY_NAME.CURRVAL FROM dual from the backend.

Remember, CURRVAL is only callable if NEXTVAL has been priorly invoked, which is all naturally done in the strategy above...

      beforeShow: function(el) {
            if ( el.getAttribute("readonly") !== null ) {
                if ( (el.value == null) || (el.value == '') ) {
                    $(el).datepicker( "option", "minDate", +1 );
                    $(el).datepicker( "option", "maxDate", -1 );
                } else {
                    $(el).datepicker( "option", "minDate", el.value );
                    $(el).datepicker( "option", "maxDate", el.value );
                }
            }
        },

I have made a jsfiddle for you.

Tested in Chrome38, IE11 and Firefox 33. Seems to have issues with Safari. However, Andrew got it working in Safari 8 on Mac OSx by switching to JPEG from PNG. For details, see his comment below.

Assuming, as seems to be the case, ${triningIdArray} is a server-side placeholder that is replaced with JS array-literal syntax, just lose the quotes. So:

var traingIds = ${triningIdArray};

not

var traingIds = "${triningIdArray}";

You can just go for String replace method.-

line1 = line1.replace("\"", "");

Instead of "this is what worked for me" answers and other answers that look like complete hacks... This is currently how chrome (and the latest spec) will handle the autocomplete attributes on your input elements:

https://developers.google.com/web/fundamentals/design-and-ui/input/forms/label-and-name-inputs?hl=en

TLDR: Add autocomplete='<value>' on your inputs, where <value> should be any string that defines what the field is for. This works similarly to the name attribute. Use the suggested values on the link above where possible.

Also, remove the autocomplete attribute from your form

Use the JSON.stringify() to get the string in JSON format, ensure that while making the AJAX call you pass below mentioned attributes:

• contentType: 'application/json'

Below is the give jquery code to make ajax post call to asp.net web api:

var product =_x000D_
    JSON.stringify({_x000D_
        productGroup: "Fablet",_x000D_
        productId: 1,_x000D_
        productName: "Lumia 1525 64 GB",_x000D_
        sellingPrice: 700_x000D_
    });_x000D_
_x000D_
$.ajax({_x000D_
    URL: 'http://localhost/api/Products',_x000D_
    type: 'POST',_x000D_
    contentType: 'application/json',_x000D_
    data: product,_x000D_
    success: function (data, status, xhr) {_x000D_
        alert('Success!');_x000D_
    },_x000D_
    error: function (xhr, status, error) {_x000D_
        alert('Update Error occurred - ' + error);_x000D_
    }_x000D_
});

This works as of now - and is documented on facebook's site @ http://developers.facebook.com/docs/authentication/. Not sure how recently it was added to the documentation, pretty sure it wasn't there when I checked Feb-2012

You can programmatically log the user our of Facebook by redirecting the user to

While existing answers definitely solve the purpose, if your'e looking to replicate nested directory structure under two different subdirectories, then you can do this

mkdir -p {main,test}/{resources,scala/com/company}

It will create following directory structure under the directory from where it is invoked

+-- main
¦   +-- resources
¦   +-- scala
¦       +-- com
¦           +-- company
+-- test
    +-- resources
    +-- scala
        +-- com
            +-- company

The example was taken from this link for creating SBT directory structure

A negative lookahead says, at this position, the following regex can not match.

Let's take a simplified example:

a(?!b(?!c))

a      Match: (?!b) succeeds
ac     Match: (?!b) succeeds
ab     No match: (?!b(?!c)) fails
abe    No match: (?!b(?!c)) fails
abc    Match: (?!b(?!c)) succeeds

The last example is a double negation: it allows a b followed by c. The nested negative lookahead becomes a positive lookahead: the c should be present.

In each example, only the a is matched. The lookahead is only a condition, and does not add to the matched text.

Create your xml in drawable, layout_background.xml

 <?xml version="1.0" encoding="utf-8"?>
    <shape xmlns:android="http://schemas.android.com/apk/res/android" >
      <solid android:color="@color/your_colour" />
      <stroke
            android:width="2dp"
            android:color="@color/your_colour" />
      <corners android:radius="10dp" />      
    </shape>
 <--width, color, radius should be as per your requirement-->

and then, add this in your layout.xml

 android:background="@drawable/layout_background"

A newer way to do this in .NET Core is with TagHelpers.

https://docs.microsoft.com/en-us/aspnet/core/mvc/views/tag-helpers/intro

Building on these examples (MaxLength, Label), you can extend the existing TagHelper to suit your needs.

RequiredTagHelper.cs

using Microsoft.AspNetCore.Razor.TagHelpers;
using System.ComponentModel.DataAnnotations;
using System.Collections.Generic;
using Microsoft.AspNetCore.Mvc.ViewFeatures;
using System.Linq;

namespace ProjectName.TagHelpers
{
    [HtmlTargetElement("input", Attributes = "asp-for")]
    public class RequiredTagHelper : TagHelper
    {
        public override int Order
        {
            get { return int.MaxValue; }
        }

        [HtmlAttributeName("asp-for")]
        public ModelExpression For { get; set; }

        public override void Process(TagHelperContext context, TagHelperOutput output)
        {
            base.Process(context, output); 

            if (context.AllAttributes["required"] == null)
            {
                var isRequired = For.ModelExplorer.Metadata.ValidatorMetadata.Any(a => a is RequiredAttribute);
                if (isRequired)
                {
                    var requiredAttribute = new TagHelperAttribute("required");
                    output.Attributes.Add(requiredAttribute);
                }
            }
        }
    }
}

You'll then need to add it to be used in your views:

_ViewImports.cshtml

@using ProjectName
@addTagHelper *, Microsoft.AspNetCore.Mvc.TagHelpers
@addTagHelper "*, ProjectName"

Given the following model:

Foo.cs

using System;
using System.ComponentModel.DataAnnotations;

namespace ProjectName.Models
{
    public class Foo
    {
        public int Id { get; set; }

        [Required]
        [Display(Name = "Full Name")]
        public string Name { get; set; }
    }
}

and view (snippet):

New.cshtml

<label asp-for="Name"></label>
<input asp-for="Name"/>

Will result in this HTML:

<label for="Name">Full Name</label>
<input required type="text" data-val="true" data-val-required="The Full Name field is required." id="Name" name="Name" value=""/>

I hope this is helpful to anyone with same question but using .NET Core.

You can use a combiation of LEFT and CHARINDEX to find the index of the first space, and then grab everything to the left of that.

 SELECT LEFT(YourColumn, charindex(' ', YourColumn) - 1) 

And in case any of your columns don't have a space in them:

SELECT LEFT(YourColumn, CASE WHEN charindex(' ', YourColumn) = 0 THEN 
    LEN(YourColumn) ELSE charindex(' ', YourColumn) - 1 END)

There are 3 (at least) parts to this.

Part 1: As everyone else suggested...Ensure the folder and containing files are not read only. You will read about a phantom bug in windows where you remove read only from folders and containing items, only to open the properties again and see it still clicked. This is not a bug. Honestly, its a feature. You see back in the early days. The System and Read Only attributes had specific meanings. Now that windows has evolved and uses a different file system these attributes no longer make sense on folders. So they have been "repurposed" as a marker for the OS to identify folders that have special meaning or customisations (and as such contain the desktop.ini file). Folders such as those containing fonts or special icons and customisations etc. So even though this attribute is still turned on, it doesn't affect the files within them. So it can be ignored once you have turned it off the first time.

Part 2: Again, as others have suggested, right click the database, and properties, find options, ensure that the read only property is set to false. You generally wont be able to change this manually anyway unless you are lucky. But before you go searching for magic commands (sql or powershell), take a look at part 3.

Part 3: Check the permissions on the folder. Ensure your SQL Server user has full access to it. In most cases this user for a default installation is either MSSQLSERVER or MSSQLEXPRESS with "NT Service" prefixed. You'll find them in the security\logins section of the database. Open the properties of the folder, go to the security tab, and add that user to the list.

In all 3 cases you may (or may not) have to detach and reattach to see the read only status removed.

If I find a situation where these 3 solutions don't work for me, and I find another alternative, I will add it here in time. Hope this helps.

This is a great one I discovered recently - it lets you select a rectangular section of text regardless of line breaks. Very handy for clipping out a subquery or list quickly.

You can include in your SVG files link to external css file using:

<link xmlns="http://www.w3.org/1999/xhtml" rel="stylesheet" href="mystyles.css" type="text/css"/>

You need to put this after opening tag:

<svg>
  <link xmlns="http://www.w3.org/1999/xhtml" rel="stylesheet" href="mystyles.css" type="text/css"/>
  <g>
    <path d=.../>
  </g>
</svg>

It's not perfect solution, because you have to modify svg files, but you modify them once and than all styling changes can be done in one css file for all svg files.

Getting this error, I changed the

I have decompiled Google Play services revision 14 library. I think there is a bug in com.google.android.gms.common.GooglePlayServicesUtil.class. The aforementioned string appears only in one place:

public static int isGooglePlayServicesAvailable(Context context) {
    PackageManager localPackageManager = context.getPackageManager();
    try {
        Resources localResources = context.getResources();
        localResources.getString(R.string.common_google_play_services_unknown_issue);
    } catch (Throwable localThrowable1) {
        Log.e("GooglePlayServicesUtil", "The Google Play services resources were not found. "
                + "Check your project configuration to ensure that the resources are included.");
    }
....

There is no R.class in com.google.android.gms.common package.

There is an import com.google.android.gms.R.string;, but no usage of string.something, so I guess this is the error - there should be import com.google.android.gms.R;.

Nevertheless the isGooglePlayServicesAvailable method works as intended (except of logging that warning), but there are other methods in that class, which uses unimported R.class, so there may be some other errors. Although banners in my application works fine...

df[df['ids'].str.contains('ball', na = False)] # valid for (at least) pandas version 0.17.1

Step-by-step explanation (from inner to outer):

• df['ids'] selects the ids column of the data frame (technically, the object df['ids'] is of type pandas.Series)
• df['ids'].str allows us to apply vectorized string methods (e.g., lower, contains) to the Series
• df['ids'].str.contains('ball') checks each element of the Series as to whether the element value has the string 'ball' as a substring. The result is a Series of Booleans indicating True or False about the existence of a 'ball' substring.
• df[df['ids'].str.contains('ball')] applies the Boolean 'mask' to the dataframe and returns a view containing appropriate records.
• na = False removes NA / NaN values from consideration; otherwise a ValueError may be returned.

I kept getting this error, when using wildcard subdomains with my app. I had the site url set to: http://myapp.com and app domain also to http://myapp.com, and also the same value for the Valid OAuth redirect URIs in the advanced tab of the settings app. I tried different combinations but only setting the http://subdomain.myapp.com as the redirect value worked, of course only for that subdomain.

The solution was to empty the redirect fields, leave it blank, that worked! ;)

Sometimes this issue comes because the java.version which you have mentioned in POM.xml is not the one installed in your machine.

<properties>
    <java.version>1.7</java.version>
</properties>

Ensure you exactly mention the same version in your pom.xml as the jdk and jre version present in your machine.

It has to do with how the list comprehension is performed.

Keep in mind the following:

[ expression for item in list if conditional ]

Is equivalent to:

for item in list:
    if conditional:
        expression

Where the expression is in a slightly different format (think switching the subject and verb order in a sentence).

Therefore, your code [x+1 for x in l if x >= 45] does this:

for x in l:
    if x >= 45:
        x+1

However, this code [x+1 if x >= 45 else x+5 for x in l] does this (after rearranging the expression):

for x in l:
    if x>=45: x+1
    else: x+5

Here's a custom theme to make the ggplot2 background white and a bunch of other changes that's good for publications and posters. Just tack on +mytheme. If you want to add or change options by +theme after +mytheme, it will just replace those options from +mytheme.

library(ggplot2)
library(cowplot)
theme_set(theme_cowplot())

mytheme = list(
    theme_classic()+
        theme(panel.background = element_blank(),strip.background = element_rect(colour=NA, fill=NA),panel.border = element_rect(fill = NA, color = "black"),
              legend.title = element_blank(),legend.position="bottom", strip.text = element_text(face="bold", size=9),
              axis.text=element_text(face="bold"),axis.title = element_text(face="bold"),plot.title = element_text(face = "bold", hjust = 0.5,size=13))
)

ggplot(data=data.frame(a=c(1,2,3), b=c(2,3,4)), aes(x=a, y=b)) + mytheme + geom_line()

In xcode5 from Preferences, Accounts, (select your account), View Details, press refresh button. then select Provision Profile in build settings.

If you know what you're doing, you can define a class with implicit operators to convert between the alias class and the actual class.

class TypedefString // Example with a string "typedef"
{
    private string Value = "";
    public static implicit operator string(TypedefString ts)
    {
        return ((ts == null) ? null : ts.Value);
    }
    public static implicit operator TypedefString(string val)
    {
        return new TypedefString { Value = val };
    }
}

I don't actually endorse this and haven't ever used something like this, but this could probably work for some specific circumstances.

I also had a similar problem like yours. The problem is that you are using an old php version. I have upgraded to PHP 5.6 and the problem no longer exist.

I think todays, it is better to use, but only with C++17.

#include <type_traits>

template <typename T>
void foo() {
    if constexpr (std::is_same_v<T, animal>) {
        // use type specific operations... 
    } 
}

If you use some type specific operations in if expression body without constexpr, this code will not compile.

zxing does not (only) provide a web API; really, that is Google providing the API, from source code that was later open-sourced in the project.

As Rob says here you can use the Java source code for the QR code encoder to create a raw barcode and then render it as a Bitmap.

I can offer an easier way still. You can call Barcode Scanner by Intent to encode a barcode. You need just a few lines of code, and two classes from the project, under android-integration. The main one is IntentIntegrator. Just call shareText().

Well, I made a simple two liner script for this, Its small and does what u want.

Edit 08/13/2018: There is now support for native array operations in Cloud Firestore. See Doug's answer below.

There is currently no way to update a single array element (or add/remove a single element) in Cloud Firestore.

This code here:

firebase.firestore()
.collection('proprietary')
.doc(docID)
.set(
  { sharedWith: [{ who: "[email protected]", when: new Date() }] },
  { merge: true }
)

This says to set the document at proprietary/docID such that sharedWith = [{ who: "[email protected]", when: new Date() } but to not affect any existing document properties. It's very similar to the update() call you provided however the set() call with create the document if it does not exist while the update() call will fail.

So you have two options to achieve what you want.

Option 1 - Set the whole array

Call set() with the entire contents of the array, which will require reading the current data from the DB first. If you're concerned about concurrent updates you can do all of this in a transaction.

Option 2 - Use a subcollection

You could make sharedWith a subcollection of the main document. Then adding a single item would look like this:

firebase.firestore()
  .collection('proprietary')
  .doc(docID)
  .collection('sharedWith')
  .add({ who: "[email protected]", when: new Date() })

Of course this comes with new limitations. You would not be able to query documents based on who they are shared with, nor would you be able to get the doc and all of the sharedWith data in a single operation.

For someone new to all this and if accidentally landed here

As of now all AMI's in quickstart section are EBS backed

Also there's a good explanation at official doc for difference between EBS and Instance store

If you're on Windows and have no time finding a nice grep alternative, a quick and dirty way would be:

aws s3 ls s3://your-bucket/folder/ --recursive > myfile.txt

and then do a quick-search in myfile.txt

The "folder" bit is optional.

P.S. if you don't have AWS CLI installed - here's a one liner using Chocolatey package manager

choco install awscli

P.P.S. If you don't have the Chocolatey package manager - get it! Your life on Windows will get 10x better. (I'm not affiliated with Chocolatey in any way, but hey, it's a must-have, really).

First is you have to understand the difference between MyISAM and InnoDB Engines. And this is clearly stated on this link. You can use this sql statement if you want to convert InnoDB to MyISAM:

 ALTER TABLE t1 ENGINE=MyISAM;

You need to use ScriptManager.RegisterStartupScript for Ajax.

protected void ButtonPP_Click(object sender, EventArgs e) {     if (radioBtnACO.SelectedIndex < 0)     {         string csname1 = "PopupScript";          var cstext1 = new StringBuilder();         cstext1.Append("alert('Please Select Criteria!')");          ScriptManager.RegisterStartupScript(this, GetType(), csname1,             cstext1.ToString(), true);     } } 

While this works:

<%-- <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="ht_tv1.Default" %> --%>
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="Blank._Default" %>

This won't.

So you can't comment out part of something which is what I want to do 99.9995% of the time.

I reached the point that I set, up to max_iter=1200000 on my LinearSVC classifier, but still the "ConvergenceWarning" was still present. I fix the issue by just setting dual=False and leaving max_iter to its default.

With LogisticRegression(solver='lbfgs') classifier, you should increase max_iter. Mine have reached max_iter=7600 before the "ConvergenceWarning" disappears when training with large dataset's features.

create a folder in main. like: 'res_notification_btn'

and create tree folder in. like 'drawable' or 'layout'

then in 'build.gradle' add this

sourceSets
            {
                main
                {
                    res
                    {
                        srcDirs = ['src/main/res_notification_btn', 'src/main/res']
                      or
                        srcDir 'src/main/res_notification_btn'
                    }
                }
            }

The problem with taking a given number and displaying it with .ToString("C", culture) is that it effectively changes the amount to the default currency of the given culture. If you have a given amount, the ISO currency code of that amount, and you want to display it for a given culture, I would recommend just creating a decimal extension method like the one below. This will not automatically assume that the currency is in the default currency of the culture:

public static string ToFormattedCurrencyString(
    this decimal currencyAmount,
    string isoCurrencyCode,
CultureInfo userCulture)
{
    var userCurrencyCode = new RegionInfo(userCulture.Name).ISOCurrencySymbol;

    if (userCurrencyCode == isoCurrencyCode)
    {
        return currencyAmount.ToString("C", userCulture);
    }

    return string.Format(
        "{0} {1}", 
        isoCurrencyCode, 
        currencyAmount.ToString("N2", userCulture));
}

This will either use the local currency symbol or the ISO currency code with the amount -- whichever is more appropriate. More on the topic in this blog post.

Here is my implementation.

try this?

Popen.communicate() documentation:

Note that if you want to send data to the process’s stdin, you need to create the Popen object with stdin=PIPE. Similarly, to get anything other than None in the result tuple, you need to give stdout=PIPE and/or stderr=PIPE too.

Replacing os.popen*

    pipe = os.popen(cmd, 'w', bufsize)
    # ==>
    pipe = Popen(cmd, shell=True, bufsize=bufsize, stdin=PIPE).stdin

Warning Use communicate() rather than stdin.write(), stdout.read() or stderr.read() to avoid deadlocks due to any of the other OS pipe buffers filling up and blocking the child process.

So your example could be written as follows:

from subprocess import Popen, PIPE, STDOUT

p = Popen(['grep', 'f'], stdout=PIPE, stdin=PIPE, stderr=STDOUT)    
grep_stdout = p.communicate(input=b'one\ntwo\nthree\nfour\nfive\nsix\n')[0]
print(grep_stdout.decode())
# -> four
# -> five
# ->

On Python 3.5+ (3.6+ for encoding), you could use subprocess.run, to pass input as a string to an external command and get its exit status, and its output as a string back in one call:

#!/usr/bin/env python3
from subprocess import run, PIPE

p = run(['grep', 'f'], stdout=PIPE,
        input='one\ntwo\nthree\nfour\nfive\nsix\n', encoding='ascii')
print(p.returncode)
# -> 0
print(p.stdout)
# -> four
# -> five
# -> 

In this case you need to go up to the <tr> then use .next(), like this:

$(obj).closest('tr').next().find('.class');

Or if there may be rows in-between without the .class inside, you can use .nextAll(), like this:

$(obj).closest('tr').nextAll(':has(.class):first').find('.class');

See the (quite) recent answer on the matplotlib repository, in which the following solution is suggested:

• If you want to set the xticklabels:

  ax.set_xticks([1,4,5]) 
  ax.set_xticklabels([1,4,5], fontsize=12)
  

• If you want to only increase the fontsize of the xticklabels, using the default values and locations (which is something I personally often need and find very handy):

  ax.tick_params(axis="x", labelsize=12) 
  

• To do it all at once:

  plt.setp(ax.get_xticklabels(), fontsize=12, fontweight="bold", 
           horizontalalignment="left")`
  

quoting @user2993582's answer

export PATH=$PATH:$ANDROID_HOME/bin

The 'bin' part has changed and it should be

export PATH=$PATH:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools

In addition to selecting all elements with an attribute $('[someAttribute]') or $('input[someAttribute]') you can also use a function for doing boolean checks on an object such as in a click handler:

if(! this.hasAttribute('myattr') ) { ...

If you want to change anything else instead of 'default', then just add these additional lines to your Vagrantfile:

Change the basebox name, when using "vagrant status"

 config.vm.define "tendo" do |tendo|
  end

Where "tendo" will be the name that will appear instead of default

Upgrade your SQL Server to SP3

You can install it from: http://www.microsoft.com/en-us/download/details.aspx?id=27594

Be sure that you have added the component to the components.

For example:

export default {
data() {
    return {}
},
components: {
    'lead-status-modal': LeadStatusModal,
},
}

To be very clear and practical:

Stub: A class or object that implements the methods of the class/object to be faked and returns always what you want.

Example in JavaScript:

var Stub = {
   method_a: function(param_a, param_b){
      return 'This is an static result';
   }
}

Mock: The same of stub, but it adds some logic that "verifies" when a method is called so you can be sure some implementation is calling that method.

As @mLevan says imagine as an example that you're testing a user registration class. After calling Save, it should call SendConfirmationEmail.

A very stupid code Example:

var Mock = {
   calls: {
      method_a: 0
   }

   method_a: function(param_a, param_b){
     this.method_a++; 
     console.log('Mock.method_a its been called!');
   }
}

Expected an assignment or function call and instead saw an expression.

I had this similar error with this code:

const mapStateToProps = (state) => {
    players: state
}

To correct all I needed to do was add parenthesis around the curved brackets

const mapStateToProps = (state) => ({
    players: state
});

$("body").stop().animate({
        scrollTop: 0
    }, 500, 'swing', function () {
        console.log(confirm('Like This'))
    }
);

String Text = mySpinner.getSelectedItem().toString();

OR

mySpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
    public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
        Object item = parent.getItemAtPosition(position);
    }
    public void onNothingSelected(AdapterView<?> parent) {
    }
});

you are using onclick which is javascript event. there is two ways

Javascript

<input type="button" value="Home" class="homebutton" id="btnHome" 
onClick="window.location = 'http://google.com'" />

Or PHP

create another page as redirect.php and put

<?php header('location : google.com') ?>

and insert this link on any page within the same directory

<a href="redirect.php">google<a/>

hope this helps its simplest!!

The fragment already has startActivityForResult, which would call onActivityResult in the fragment if you use it, instead of getActivity()...

A couple of distinctions that weren't touched on here:

• With exec(), you can pass an optional param variable which will receive an array of output lines. In some cases this might save time, especially if the output of the commands is already tabular.

Compare:

exec('ls', $out);
var_dump($out);
// Look an array

$out = shell_exec('ls');
var_dump($out);
// Look -- a string with newlines in it

Conversely, if the output of the command is xml or json, then having each line as part of an array is not what you want, as you'll need to post-process the input into some other form, so in that case use shell_exec.

It's also worth pointing out that shell_exec is an alias for the backtic operator, for those used to *nix.

$out = `ls`;
var_dump($out);

exec also supports an additional parameter that will provide the return code from the executed command:

exec('ls', $out, $status);
if (0 === $status) {
    var_dump($out);
} else {
    echo "Command failed with status: $status";
}

As noted in the shell_exec manual page, when you actually require a return code from the command being executed, you have no choice but to use exec.

When I started with $ nohup storm dev-zookeper ,

METHOD1 : using jobs,

prayagupd@prayagupd:/home/vmfest# jobs -l
[1]+ 11129 Running                 nohup ~/bin/storm/bin/storm dev-zookeeper &

METHOD2 : using ps command.

$ ps xw
PID  TTY      STAT   TIME COMMAND
1031 tty1     Ss+    0:00 /sbin/getty -8 38400 tty1
10582 ?        S      0:01 [kworker/0:0]
10826 ?        Sl     0:18 java -server -Dstorm.options= -Dstorm.home=/root/bin/storm -Djava.library.path=/usr/local/lib:/opt/local/lib:/usr/lib -Dsto
10853 ?        Ss     0:00 sshd: vmfest [priv] 

TTY column with ? => nohup running programs.

Description

• TTY column = the terminal associated with the process
• STAT column = state of a process
  • S = interruptible sleep (waiting for an event to complete)
  • l = is multi-threaded (using CLONE_THREAD, like NPTL pthreads do)

Reference

$ man ps # then search /PROCESS STATE CODES

for me, this is the fastest way:

import timeit
def foo():
    print("here is my code to time...")


timeit.timeit(stmt=foo, number=1234567)

You can raise a notice in Postgres as follows:

raise notice 'Value: %', deletedContactId;

The linked list holds operations on the shared data structure.

For example, if I have a stack, it will be manipulated with pushes and pops. The linked list would be a set of pushes and pops on the pseudo-shared stack. Each thread sharing that stack will actually have a local copy, and to get to the current shared state, it'll walk the linked list of operations, and apply each operation in order to its local copy of the stack. When it reaches the end of the linked list, its local copy holds the current state (though, of course, it's subject to becoming stale at any time).

In the traditional model, you'd have some sort of locks around each push and pop. Each thread would wait to obtain a lock, then do a push or pop, then release the lock.

In this model, each thread has a local snapshot of the stack, which it keeps synchronized with other threads' view of the stack by applying the operations in the linked list. When it wants to manipulate the stack, it doesn't try to manipulate it directly at all. Instead, it simply adds its push or pop operation to the linked list, so all the other threads can/will see that operation and they can all stay in sync. Then, of course, it applies the operations in the linked list, and when (for example) there's a pop it checks which thread asked for the pop. It uses the popped item if and only if it's the thread that requested this particular pop.

Firefox 3.6 has a full screen option for HTML5 video's, right-click on the video and select 'full screen'.

The latest Webkit nightlies also support full screen HTML5 video, try the Sublime player with the latest nightly and hold Cmd / Ctrl while selecting the full screen option.

I guess Chrome / Opera will also support something like this. Hopefully IE9 will also support full screen HTML5 video.

At the time when this question was asked there wasn't another function in Pandas to test equality, but it has been added a while ago: pandas.equals

You use it like this:

df1.equals(df2)

Some differenes to == are:

• You don't get the error described in the question
• It returns a simple boolean.
• NaN values in the same location are considered equal
• 2 DataFrames need to have the same dtype to be considered equal, see this stackoverflow question

Android Supports SSL implementation by default except for Android N (API level 24) and below Android 5.1 (API level 22)
I was getting the error when making the API call below API level 22 devices after implementing SSL at the server side; that was while creating OkHttpClient client object, and fixed by adding connectionSpecs() method OkHttpClient.Builder class.

the error received was

response failure: javax.net.ssl.SSLException: SSL handshake aborted: ssl=0xb8882c00: I/O error during system call, Connection reset by peer

so I fixed this by added the check like

if ( Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP_MR1) {
            // Do something for below api level 22
            List<ConnectionSpec> specsList = getSpecsBelowLollipopMR1(okb);
            if (specsList != null) {
                okb.connectionSpecs(specsList);
            }
        }

Also for the Android N (API level 24); I was getting the error while making the HTTP call like

HTTP FAILED: javax.net.ssl.SSLHandshakeException: Handshake failed

and this is fixed by adding the check for Android 7 particularly, like

if (android.os.Build.VERSION.SDK_INT == Build.VERSION_CODES.N){
            // Do something for naugat ; 7
            okb.connectionSpecs(Collections.singletonList(getSpec()));
        }

So my final OkHttpClient object will be like:

         OkHttpClient client
         HttpLoggingInterceptor httpLoggingInterceptor2 = new
         HttpLoggingInterceptor();
         httpLoggingInterceptor2.setLevel(HttpLoggingInterceptor.Level.BODY);

         OkHttpClient.Builder okb = new OkHttpClient.Builder()
                 .addInterceptor(httpLoggingInterceptor2)
               .addInterceptor(new Interceptor() {
                     @Override
                     public Response intercept(Chain chain) throws IOException {
                         Request request = chain.request();
                         Request request2 = request.newBuilder().addHeader(AUTH_KEYWORD, AUTH_TYPE_JW + " " + password).build();
                         return chain.proceed(request2);
                     }
                 }).connectTimeout(30, TimeUnit.SECONDS)
                 .writeTimeout(30, TimeUnit.SECONDS)
                 .readTimeout(30, TimeUnit.SECONDS);

         if (android.os.Build.VERSION.SDK_INT == Build.VERSION_CODES.N){
             // Do something for naugat ; 7
             okb.connectionSpecs(Collections.singletonList(getSpec()));
         }

         if ( Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP_MR1) {
             List<ConnectionSpec> specsList = getSpecsBelowLollipopMR1(okb);
             if (specsList != null) {
                 okb.connectionSpecs(specsList);
             }
         }

         //init client
         client = okb.build();

getSpecsBelowLollipopMR1 function be like,

   private List<ConnectionSpec> getSpecsBelowLollipopMR1(OkHttpClient.Builder okb) {

        try {

            SSLContext sc = SSLContext.getInstance("TLSv1.2");
            sc.init(null, null, null);
            okb.sslSocketFactory(new Tls12SocketFactory(sc.getSocketFactory()));

            ConnectionSpec cs = new ConnectionSpec.Builder(ConnectionSpec.MODERN_TLS)
                    .tlsVersions(TlsVersion.TLS_1_2)
                    .build();

            List<ConnectionSpec> specs = new ArrayList<>();
            specs.add(cs);
            specs.add(ConnectionSpec.COMPATIBLE_TLS);

            return specs;

        } catch (Exception exc) {
            Timber.e("OkHttpTLSCompat Error while setting TLS 1.2"+ exc);

            return null;
        }
    }

The Tls12SocketFactory class will be found in below link (comment by gotev):

D/OkHttp: <-- HTTP FAILED: javax.net.ssl.SSLException: SSL handshake aborted: ssl=0x64e3c938: I/O error during system call, Connection reset by peer

Here's a function that will do the trick:

def myformat(x):
    return ('%.2f' % x).rstrip('0').rstrip('.')

And here are your examples:

>>> myformat(1.00)
'1'
>>> myformat(1.20)
'1.2'
>>> myformat(1.23)
'1.23'
>>> myformat(1.234)
'1.23'
>>> myformat(1.2345)
'1.23'

Edit:

From looking at other people's answers and experimenting, I found that g does all of the stripping stuff for you. So,

'%.3g' % x

works splendidly too and is slightly different from what other people are suggesting (using '{0:.3}'.format() stuff). I guess take your pick.

You can just return a Boolean like this:

import org.springframework.data.jpa.repository.Query;
import org.springframework.data.jpa.repository.QueryHints;
import org.springframework.data.repository.query.Param;

@QueryHints(@QueryHint(name = org.hibernate.jpa.QueryHints.HINT_FETCH_SIZE, value = "1"))
@Query(value = "SELECT (1=1) FROM MyEntity WHERE ...... :id ....")
Boolean existsIfBlaBla(@Param("id") String id);

Boolean.TRUE.equals(existsIfBlaBla("0815")) could be a solution

did you include your tasks.py file or wherever your async methods are stored?

app = Celery('APP_NAME', broker='redis://redis:6379/0', include=['app1.tasks', 'app2.tasks', ...])

Might help someone:

when you have a formGroup in a modal (entrycomponent), then you have to import ReactiveFormsModule also in the module where the modal is instantiated.

Here's my version based loosely on Braceyard's version above but parsing into a 'dictionary' and support for search args without '='. In use it in my JQuery $(document).ready() function. The arguments are stored as key/value pairs in argsParsed, which you might want to save somewhere...

'use strict';

function parseQuery(search) {

    var args = search.substring(1).split('&');

    var argsParsed = {};

    var i, arg, kvp, key, value;

    for (i=0; i < args.length; i++) {

        arg = args[i];

        if (-1 === arg.indexOf('=')) {

            argsParsed[decodeURIComponent(arg).trim()] = true;
        }
        else {

            kvp = arg.split('=');

            key = decodeURIComponent(kvp[0]).trim();

            value = decodeURIComponent(kvp[1]).trim();

            argsParsed[key] = value;
        }
    }

    return argsParsed;
}

parseQuery(document.location.search);

Step 1: Define a class named applycolor which can be used to apply the color you choose.

Step 2: Define what actions happens to it when it hovers. If your form background is white, then you must make sure that on hover the tab does not turn white. To achieve this use the !important clause to force this feature on hover property. We are doing this to override Bootstrap's default behavior.

Step 3: Apply the class to the Tabs which you are targetting.

CSS section:

<style>
    .nav-pills > li.active > a, .nav-pills > li.active > a:hover, .nav-pills > li.active > a:focus {
        color: #fff;
        background-color: #337ab7 !important;
    }

    .nav > li > a:hover, .nav > li > a:focus {
        text-decoration: none;
        background-color: none !important;
    }

    .applycolor {
        background-color: #efefef;
        text-decoration: none;
        color: #fff;
    }

    .applycolor:hover {
        background-color: #337ab7;
        text-decoration: none;
        color: #fff;
    }
</style>

Tab Section :

<section class="form-toolbar row">
    <div class="form-title col-sm-12" id="tabs">
        <ul class="nav nav-pills nav-justified">
            <li class="applycolor"><a data-toggle="pill" href="#instance" style="font-size: 1.8rem; font-weight: 800;">My Apps</a></li>
            <li class="active applycolor"><a data-toggle="pill" href="#application" style="font-size: 1.8rem; font-weight: 800;">Apps Collection</a></li>
        </ul>
    </div>
</section>

In the earlier versions of MySQL ( < 5.7.5 ) the only way to set

'innodb_buffer_pool_size'

variable was by writing it to my.cnf (for linux) and my.ini (for windows) under [mysqld] section :

[mysqld]

innodb_buffer_pool_size = 2147483648

You need to restart your mysql server to have it's effect in action.

UPDATE :

As of MySQL 5.7.5, the innodb_buffer_pool_size configuration option can be set dynamically using a SET statement, allowing you to resize the buffer pool without restarting the server. For example:

mysql> SET GLOBAL innodb_buffer_pool_size=402653184;

Reference : https://dev.mysql.com/doc/refman/5.7/en/innodb-buffer-pool-resize.html

Headings are normally bold-faced; that has been turned off for this demonstration of size correspondence. MSIE and Opera interpret these sizes the same, but note that Gecko browsers and Chrome interpret Heading 6 as 11 pixels instead of 10 pixels/font size 1, and Heading 3 as 19 pixels instead of 18 pixels/font size 4 (though it's difficult to tell the difference even in a direct comparison and impossible in use). It seems Gecko also limits text to no smaller than 10 pixels.

I ran the same code. There are two things to note here. 1. Give the entire path of the .xml files. 2. Give a key press event instruction at the end.

Add this block of code at the end and run your file, worked for me:

k = cv2.waitKey(0)
if k == 27:         # wait for ESC key to exit
    cv2.destroyAllWindows()
elif k == ord('s'): # wait for 's' key to save and exit
    cv2.imwrite('messigray.png',img)
    cv2.destroyAllWindows()

For example, my code looked like

I had this error occur when building an Azure Function (with a queue trigger, should it make a difference)

The issue in this case was because the AzureFunctionsVersion was set to v2 instead of v3. To update it via VS2019, unload the project then edit the csproj file. Within the PropertyGroup node, add/edit the following:

<PropertyGroup>
  <AzureFunctionsVersion>v3</AzureFunctionsVersion>
</PropertyGroup>

What everyone seems to miss is that the semi-colons in JavaScript are not statement terminators but statement separators. It's a subtle difference, but it is important to the way the parser is programmed. Treat them like what they are and you will find leaving them out will feel much more natural.

I've programmed in other languages where the semi-colon is a statement separator and also optional as the parser does 'semi-colon insertion' on newlines where it does not break the grammar. So I was not unfamiliar with it when I found it in JavaScript.

I don't like noise in a language (which is one reason I'm bad at Perl) and semi-colons are noise in JavaScript. So I omit them.

man you can use the basic Bootstrap Datepicker this way:

<!DOCTYPE html>
<head runat="server">
<title>Test Zone</title>

        $('#pickyDate').datepicker({
            format: "dd/mm/yyyy"
        });
    });
</script>

and inside body:

<body>
<div id="testDIV">
    <div class="container">
        <div class="hero-unit">
            <input  type="text" placeholder="click to show datepicker"  id="pickyDate"/>

One difference is that:

• :map does nvo == normal + (visual + select) + operator pending
• :map! does ic == insert + command-line mode

as stated on help map-modes tables.

So: map does not map to all modes.

To map to all modes you need both :map and :map!.

No one will ever see this, but it's good to bring back recursion and arrow functions once in a while (pun gloriously intended)

String.prototype.occurrencesOf = function(s, i) {
 return (n => (n === -1) ? 0 : 1 + this.occurrencesOf(s, n + 1))(this.indexOf(s, (i || 0)));
};

Check Opacity, You can set this css property to the div, the <p> or using <span> you want to make transparent

And by the way, the font tag is deprecated, use css to style the text

div {
    opacity: 0.5;
} 

Edit: This code will make the whole element transparent, if you want to make ** just the text ** transparent check @Mattias Buelens answer

To answer the question:

What is the fastest way to stream live video using JavaScript? Is WebSockets over TCP a fast enough protocol to stream a video of, say, 30fps?

Yes, Websocket can be used to transmit over 30 fps and even 60 fps.

The main issue with Websocket is that it is low-level and you have to deal with may other issues than just transmitting video chunks. All in all it's a great transport for video and also audio.

This avoids using any sql

using (var context = new MyDbContext())
{
    var itemsToDelete = context.Set<MyTable>();
    context.MyTables.RemoveRange(itemsToDelete);
    context.SaveChanges();
}

That can be done with:

foo(*values)

It's better to do this through Android Studio rather than the file browser as it updates all icon files with the correct resolution for each.

To do so go to menu File ? New ? Image Asset. This will open a new dialogue and then make sure Launcher Icons is selected (Which it is by default) and then browse to the directory of your icon (it doesn't have to be in the project resources) and then once selected make sure other settings are to your liking and hit done.

Now all resolutions are saved into their respective folders, and you don't have to worry about copying it yourself or using tools, etc.

Don't forget "Shape - none" for a transparent background.

Using vlines:

import numpy as np
np.random.seed(5)
x = arange(1, 101)
y = 20 + 3 * x + np.random.normal(0, 60, 100)
p =  plot(x, y, "o")
vlines(70,100,250)

The basic call signatures are:

vlines(x, ymin, ymax)
hlines(y, xmin, xmax)

SELECT ID, 
    abc = STUFF(
                 (SELECT ',' + name FROM temp1 FOR XML PATH ('')), 1, 1, ''
               ) 
FROM temp1 GROUP BY id

Here in the above query STUFF function is used to just remove the first comma (,) from the generated xml string (,aaa,bbb,ccc,ddd,eee) then it will become (aaa,bbb,ccc,ddd,eee).

And FOR XML PATH('') simply converts column data into (,aaa,bbb,ccc,ddd,eee) string but in PATH we are passing '' so it will not create a XML tag.

And at the end we have grouped records using ID column.

new Long(Integer.longValue());

or

new Long(Integer.toString());

You'll need AJAX if you want to update a part of your page without reloading the entire page.

main cshtml view

<div id="refTable">
     <!-- partial view content will be inserted here -->
</div>

@Html.TextBox("yearSelect3", Convert.ToDateTime(tempItem3.Holiday_date).Year.ToString());
<button id="pY">PrevY</button>

<script>
    $(document).ready(function() {
        $("#pY").on("click", function() {
            var val = $('#yearSelect3').val();
            $.ajax({
                url: "/Holiday/Calendar",
                type: "GET",
                data: { year: ((val * 1) + 1) }
            })
            .done(function(partialViewResult) {
                $("#refTable").html(partialViewResult);
            });
        });
    });
</script>

You'll need to add the fields I have omitted. I've used a <button> instead of submit buttons because you don't have a form (I don't see one in your markup) and you just need them to trigger javascript on the client side.

The HolidayPartialView gets rendered into html and the jquery done callback inserts that html fragment into the refTable div.

HolidayController Update action

[HttpGet]
public ActionResult Calendar(int year)
{
    var dates = new List<DateTime>() { /* values based on year */ };
    HolidayViewModel model = new HolidayViewModel {
        Dates = dates
    };
    return PartialView("HolidayPartialView", model);
}

This controller action takes the year parameter and returns a list of dates using a strongly-typed view model instead of the ViewBag.

view model

public class HolidayViewModel
{
    IEnumerable<DateTime> Dates { get; set; }
}

HolidayPartialView.csthml

@model Your.Namespace.HolidayViewModel;

<table class="tblHoliday">
    @foreach(var date in Model.Dates)
    {
        <tr><td>@date.ToString("MM/dd/yyyy")</td></tr>
    }
</table>

This is the stuff that gets inserted into your div.

This header is defined in RFC 2183, so that would be the best place to start reading.

Permitted values are those registered with the Internet Assigned Numbers Authority (IANA); their registry of values should be seen as the definitive source.

You can do this via local storage API. Note that this works only between 2 tabs. you can't put both sender and receiver on the same page:

On sender page:

localStorage.setItem("someKey", "someValue");

On the receiver page

    $(document).ready(function () {

        window.addEventListener('storage', storageEventHandler, false);

        function storageEventHandler(evt) {
            alert("storage event called key: " + evt.key);
        }
    });

1)TempData

Allows you to store data that will survive for a redirect. Internally it uses the Session as backing store, after the redirect is made the data is automatically evicted. The pattern is the following:

public ActionResult Foo()
{
    // store something into the tempdata that will be available during a single redirect
    TempData["foo"] = "bar";

    // you should always redirect if you store something into TempData to
    // a controller action that will consume this data
    return RedirectToAction("bar");
}

public ActionResult Bar()
{
    var foo = TempData["foo"];
    ...
}

2)ViewBag, ViewData

Allows you to store data in a controller action that will be used in the corresponding view. This assumes that the action returns a view and doesn't redirect. Lives only during the current request.

The pattern is the following:

public ActionResult Foo()
{
    ViewBag.Foo = "bar";
    return View();
}

and in the view:

@ViewBag.Foo

or with ViewData:

public ActionResult Foo()
{
    ViewData["Foo"] = "bar";
    return View();
}

and in the view:

@ViewData["Foo"]

ViewBag is just a dynamic wrapper around ViewData and exists only in ASP.NET MVC 3.

This being said, none of those two constructs should ever be used. You should use view models and strongly typed views. So the correct pattern is the following:

View model:

public class MyViewModel
{
    public string Foo { get; set; }
}

Action:

public Action Foo()
{
    var model = new MyViewModel { Foo = "bar" };
    return View(model);
}

Strongly typed view:

@model MyViewModel
@Model.Foo

After this brief introduction let's answer your question:

My requirement is I want to set a value in a controller one, that controller will redirect to ControllerTwo and Controller2 will render the View.

public class OneController: Controller
{
    public ActionResult Index()
    {
        TempData["foo"] = "bar";
        return RedirectToAction("index", "two");
    }
}

public class TwoController: Controller
{
    public ActionResult Index()
    {
        var model = new MyViewModel
        {
            Foo = TempData["foo"] as string
        };
        return View(model);
    }
}

and the corresponding view (~/Views/Two/Index.cshtml):

@model MyViewModel
@Html.DisplayFor(x => x.Foo)

There are drawbacks of using TempData as well: if the user hits F5 on the target page the data will be lost.

Personally I don't use TempData neither. It's because internally it uses Session and I disable session in my applications. I prefer a more RESTful way to achieve this. Which is: in the first controller action that performs the redirect store the object in your data store and user the generated unique id when redirecting. Then on the target action use this id to fetch back the initially stored object:

public class OneController: Controller
{
    public ActionResult Index()
    {
        var id = Repository.SaveData("foo");
        return RedirectToAction("index", "two", new { id = id });
    }
}

public class TwoController: Controller
{
    public ActionResult Index(string id)
    {
        var model = new MyViewModel
        {
            Foo = Repository.GetData(id)
        };
        return View(model);
    }
}

The view stays the same.

Go to Phone Settings --> Developer Options --> Simulate Secondary Displays and turn it to None. If you don't see Developer Options in the settings menu (it should be at the bottom, go Settings ==> About phone and tap on the Build number a lot of times)

Remember that when you write:

MyArray = Range("A1:A5000")

you are really writing

MyArray = Range("A1:A5000").Value

You can also use names:

MyArray = Names("MyWSTable").RefersToRange.Value

But Value is not the only property of Range. I have used:

MyArray = Range("A1:A5000").NumberFormat

I doubt

MyArray = Range("A1:A5000").Font

would work but I would expect

MyArray = Range("A1:A5000").Font.Bold

to work.

I do not know what formats you want to copy so you will have to try.

However, I must add that when you copy and paste a large range, it is not as much slower than doing it via an array as we all thought.

Post Edit information

Having posted the above I tried by own advice. My experiments with copying Font.Color and Font.Bold to an array have failed.

Of the following statements, the second would fail with a type mismatch:

  ValueArray = .Range("A1:T5000").Value
  ColourArray = .Range("A1:T5000").Font.Color

ValueArray must be of type variant. I tried both variant and long for ColourArray without success.

I filled ColourArray with values and tried the following statement:

  .Range("A1:T5000").Font.Color = ColourArray

The entire range would be coloured according to the first element of ColourArray and then Excel looped consuming about 45% of the processor time until I terminated it with the Task Manager.

There is a time penalty associated with switching between worksheets but recent questions about macro duration have caused everyone to review our belief that working via arrays was substantially quicker.

I constructed an experiment that broadly reflects your requirement. I filled worksheet Time1 with 5000 rows of 20 cells which were selectively formatted as: bold, italic, underline, subscript, bordered, red, green, blue, brown, yellow and gray-80%.

With version 1, I copied every 7th cells from worksheet "Time1" to worksheet "Time2" using copy.

With version 2, I copied every 7th cells from worksheet "Time1" to worksheet "Time2" by copying the value and the colour via an array.

With version 3, I copied every 7th cells from worksheet "Time1" to worksheet "Time2" by copying the formula and the colour via an array.

Version 1 took an average of 12.43 seconds, version 2 took an average of 1.47 seconds while version 3 took an average of 1.83 seconds. Version 1 copied formulae and all formatting, version 2 copied values and colour while version 3 copied formulae and colour. With versions 1 and 2 you could add bold and italic, say, and still have some time in hand. However, I am not sure it would be worth the bother given that copying 21,300 values only takes 12 seconds.

The User type definition must be placed before any subroutine in the module. The code works through the source worksheet copying values or formulae and colours to the next element of the array. Once selection has been completed, it copies the collected information to the destination worksheet. This avoids switching between worksheets more than is essential.

If you're doing any sort of development you need to point to the JDK (Java Development Kit). Otherwise, you can point to the JRE (Java Runtime Environment).

The JDK contains everything the JRE has and more. If you're just executing Java programs, you can point to either the JRE or the JDK.

You should set JAVA_HOME based on current Java you are using. readlink will print value of a symbolic link for current Java and sed will adjust it to JRE directory:

export JAVA_HOME=$(readlink -f /usr/bin/java | sed "s:bin/java::")

If you want to set up JAVA_HOME to JDK you should go up one folder more:

export JAVA_HOME=$(readlink -f /usr/bin/java | sed "s:jre/bin/java::")

The answer with the :a label ...

How can I replace a newline (\n) using sed?

... does not work in freebsd 7.2 on the command line:

( echo foo ; echo bar ) | sed ':a;N;$!ba;s/\n/ /g'
sed: 1: ":a;N;$!ba;s/\n/ /g": unused label 'a;N;$!ba;s/\n/ /g'
foo
bar

But does if you put the sed script in a file or use -e to "build" the sed script...

> (echo foo; echo bar) | sed -e :a -e N -e '$!ba' -e 's/\n/ /g'
foo bar

or ...

> cat > x.sed << eof
:a
N
$!ba
s/\n/ /g
eof

> (echo foo; echo bar) | sed -f x.sed
foo bar

Maybe the sed in OS X is similar.

You can extract text by area in PDFBox. See the ExtractByArea.java example file, in the pdfbox-examples artifact if you're using Maven. A snippet looks like

   PDFTextStripperByArea stripper = new PDFTextStripperByArea();
   stripper.setSortByPosition( true );
   Rectangle rect = new Rectangle( 464, 59, 55, 5);
   stripper.addRegion( "class1", rect );
   stripper.extractRegions( page );
   String string = stripper.getTextForRegion( "class1" );

The problem is getting the coordinates in the first place. I've had success extending the normal TextStripper, overriding processTextPosition(TextPosition text) and printing out the coordinates for each character and figuring out where in the document they are.

But there's a much simpler way, at least if you're on a Mac. Open the PDF in Preview, ?I to show the Inspector, choose the Crop tab and make sure the units are in Points, from the Tools menu choose Rectangular selection, and select the area of interest. If you select an area, the inspector will show you the coordinates, which you can round and feed into the Rectangle constructor arguments. You just need to confirm where the origin is, using the first method.

Or you can just use the <center></center> tags.

I had this same issue and wondered why it didn't happen with a bitbucket repo that was cloned with https. Looking into it a bit I found that the config for the BB repo had a URL that included my username. So I manually edited the config for my GH repo like so and voila, no more username prompt. I'm on Windows.

Edit your_repo_dir/.git/config (remember: .git folder is hidden)

Change:

https://github.com/WEMP/project-slideshow.git

to:

https://*username*@github.com/WEMP/project-slideshow.git

Save the file. Do a git pull to test it.

The proper way to do this is probably by using git bash commands to edit the setting, but editing the file directly didn't seem to be a problem.

We had the same issue and we resolved it using Spring's XML configuration as below:

Add this in your context xml file

<mvc:cors>
    <mvc:mapping path="/**"
        allowed-origins="*"
        allowed-headers="Content-Type, Access-Control-Allow-Origin, Access-Control-Allow-Headers, Authorization, X-Requested-With, requestId, Correlation-Id"
        allowed-methods="GET, PUT, POST, DELETE"/>
</mvc:cors>

Actual SETUP:

• OS: Windows 8.1
• JDK file: jdk-8u11-windows-x64.exe
• ADT file: installer_r23.0.2-windows.exe

Install the x64 JDK, and try the back-next option first, and then try setting JAVA_HOME like the error message says, but if that doesn't work for you either, then try this:

Do as it says, set JAVA_HOME in your environment variables, but in the path use forward slashes instead of backslashes.

Seriously.

For me it failed when JAVA_HOME was C:\Program Files\Java\jdk1.6.0_31 but worked fine when it was C:/Program Files/Java/jdk1.6.0_31 - drove me nuts!

If this is not enough, also add to the beginning of the Environment Variable Path %JAVA_HOME%;

Updated values in System Environment Variables:

• JAVA_HOME=C:/Program Files/Java/jdk1.8.0_11
• JRE_HOME=C:/Program Files/Java/jre8
• Path=%JAVA_HOME%;C:...

In my case I was setting the RecyclerView's layoutManager both in XML and in onViewCreated. Removing the assignment in onViewCreated fixed it.

with(_binding.list) {
//  layoutManager =  LinearLayoutManager(context)
    adapter = MyAdapter().apply {
        listViewModel.data.observe(viewLifecycleOwner,
            Observer {
                it?.let { setItems(it) }
            })
    }
}

When you define a server in server view, then it will create you a server runtime library with server libs (including servlet api), that can be assigned to your project. However, then everybody that uses your project, need to create the same type of runtime in his/her eclipse workspace even for compiling.

If you directly download the servlet api jar, than it could lead to problems, since it will be included into the artifacts of your projects, but will be also present in servlet container.

In Maven it is much nicer, since you can define the servlet api interfaces as a "provided" dependency, that means it is present in the "to be production" environment.

I noticed there was not an actual full code answer, so as i come across this, i have created a function, that does change the font, which can be easily modified. I have tested this in

- XP SP3 and Win 10 Pro 64

private void SetFont(Form f, string name, int size, FontStyle style)
{
    Font replacementFont = new Font(name, size, style);
    f.Font = replacementFont;
}

Hint: replace Form to either Label, RichTextBox, TextBox, or any other relative control that uses fonts to change the font on them. By using the above function thus making it completely dynamic.

    /// To call the function do this.
    /// e.g in the form load event etc.

public Form1()
{
      InitializeComponent();
      SetFont(this, "Arial", 8, FontStyle.Bold);  
      // This sets the whole form and 
      // everything below it.
      // Shaun Cassidy.
}

You can also, if you want a full libary so you dont have to code all the back end bits, you can download my dll from Github.

Github DLL

/// and then import the namespace
using Droitech.TextFont;

/// Then call it using:
TextFontClass fClass = new TextFontClass();
fClass.SetFont(this, "Arial", 8, FontStyle.Bold);

Simple.

getDay() gets the day of the week. 3 is Wednesday. You want getDate(), that will return 18.

Also getMonth() starts at 0, you need to add 1 to get 4 (April).

I only use MicrosoftAdvertising.Mobile and Microsoft.Advertising.Mobile.UI and I am served ads. The SDK should only add the DLLs not reference itself.

Note: You need to explicitly set width and height Make sure the phone dialer, and web browser capabilities are enabled

Followup note: Make sure that after you've removed the SDK DLL, that the xmlns references are not still pointing to it. The best route to take here is

1. Remove the XAML for the ad
2. Remove the xmlns declaration (usually at the top of the page, but sometimes will be declared in the ad itself)
3. Remove the bad DLL (the one ending in .SDK )
4. Do a Clean and then Build (clean out anything remaining from the DLL)
5. Add the xmlns reference (actual reference is below)
6. Add the ad to the page (example below)

Here is the xmlns reference:

xmlns:AdNamepace="clr-namespace:Microsoft.Advertising.Mobile.UI;assembly=Microsoft.Advertising.Mobile.UI" 

Then the ad itself:

<AdNamespace:AdControl x:Name="myAd" Height="80" Width="480"                    AdUnitId="yourAdUnitIdHere" ApplicationId="yourIdHere"/> 

The STAThreadAttribute marks a thread to use the Single-Threaded COM Apartment if COM is needed. By default, .NET won't initialize COM at all. It's only when COM is needed, like when a COM object or COM Control is created or when drag 'n' drop is needed, that COM is initialized. When that happens, .NET calls the underlying CoInitializeEx function, which takes a flag indicating whether to join the thread to a multi-threaded or single-threaded apartment.

and

Why is STAThread required?

You have multiple ways to set : as the separator:

awk -F: '{print $1}'

awk -v FS=: '{print $1}'

awk '{print $1}' FS=:

awk 'BEGIN{FS=":"} {print $1}'

All of them are equivalent and will return 1 given a sample input "1:2:3":

$ awk -F: '{print $1}' <<< "1:2:3"
1
$ awk -v FS=: '{print $1}' <<< "1:2:3"
1
$ awk '{print $1}' FS=: <<< "1:2:3"
1
$ awk 'BEGIN{FS=":"} {print $1}' <<< "1:2:3"
1
