If you are trying to reference a commit in another repo than the issue is in, you can prefix the commit short hash with reponame@.

Suppose your commit is in the repo named dev, and the GitLab issue is in the repo named test. You can leave a comment on the issue and reference the commit by dev@e9c11f0a (where e9c11f0a is the first 8 letters of the sha hash of the commit you want to link to) if that makes sense.

Just use powershell..

Run powershell and cd to the parent folder and then:

rm [yourfolder]

as in:

rm node_modules

You can override any built-in function by just re-declaring it.

parseFloat = function(a){
  alert(a)
};

Now parseFloat(3) will alert 3.

You should download the chromeDriver in a folder, and add this folder in your PATH environment variable.

You'll have to restart your console to make it work.

Yes, you can use find_elements_by_ to retrieve children elements into a list. See the python bindings here: http://selenium-python.readthedocs.io/locating-elements.html

Example HTML:

<ul class="bar">
    <li>one</li>
    <li>two</li>
    <li>three</li>
</ul>

You can use the find_elements_by_ like so:

parentElement = driver.find_element_by_class_name("bar")
elementList = parentElement.find_elements_by_tag_name("li")

If you want help with a specific case, you can edit your post with the HTML you're looking to get parent and children elements from.

Try running these two commands in the terminal:

1. sudo killall mysqld sudo
2. /Applications/XAMPP/xamppfiles/bin/mysql.server start

I found I could improve the situation a little with CSS dedicated to Webkit (Safari, Chrome). However, I had to set a fixed width and height on the field because the font change will resize the field.

@media screen and (-webkit-min-device-pixel-ratio:0){ /* START WEBKIT */
  INPUT[type="password"]{
  font-family:Verdana,sans-serif;
  height:28px;
  font-size:19px;
  width:223px;
  padding:5px;
  }
} /* END WEBKIT */

These days, there's a better solution for importing an existing PHP project. The PDT plugin now has an option on the New PHP Project dialog just for this. So:

From File->New->PHP Project:

The parameterless form of the change() method triggers a change event. You can write something like:

$(document).ready(function() {
    $("#yourInitialElementID").change(function() {
        // Do something here...
        $(".yourDropDownClass").change();
    });
});

Good technical & logical question my dear friend. No in robots.txt file you can't go with relative URL of the sitemap; you need to go with the complete URL of the sitemap.

It's better to go with "sitemap: https://www.example.com/sitemap_index.xml"

In the above URL after the colon gives space. I also like to support Deepak.

In Python 3, we use the bytes object, also known as str in Python 2.

# Python 3
key = bytes([0x13, 0x00, 0x00, 0x00, 0x08, 0x00])

# Python 2
key = ''.join(chr(x) for x in [0x13, 0x00, 0x00, 0x00, 0x08, 0x00])

I find it more convenient to use the base64 module...

# Python 3
key = base64.b16decode(b'130000000800')

# Python 2
key = base64.b16decode('130000000800')

You can also use literals...

# Python 3
key = b'\x13\0\0\0\x08\0'

# Python 2
key = '\x13\0\0\0\x08\0'

i have tried this article Code Project, it is working fine for me. I have used the code too. article is excellent in explanation with screenshot.

I am adding necessary explanation to this scenario

You have just booted up your computer and are about to log on. When you log on, the system assigns you a unique Session ID. In Windows Vista, the first User to log on to the computer is assigned a Session ID of 1 by the OS. The next User to log on will be assigned a Session ID of 2. And so on and so forth. You can view the Session ID assigned to each logged on User from the Users tab in Task Manager.

But your windows service is brought under session ID of 0. This session is isolated from other sessions. This ultimately prevent the windows service to invoke the application running under user session's like 1 or 2.

In order to invoke the application from windows service you need to copy the control from winlogon.exe which acts as present logged user as shown in below screenshot.

Important codes

// obtain the process id of the winlogon process that 
// is running within the currently active session
Process[] processes = Process.GetProcessesByName("winlogon");
foreach (Process p in processes)
{
    if ((uint)p.SessionId == dwSessionId)
    {
        winlogonPid = (uint)p.Id;
    }
}

// obtain a handle to the winlogon process
hProcess = OpenProcess(MAXIMUM_ALLOWED, false, winlogonPid);

// obtain a handle to the access token of the winlogon process
if (!OpenProcessToken(hProcess, TOKEN_DUPLICATE, ref hPToken))
{
    CloseHandle(hProcess);
    return false;
}

// Security attibute structure used in DuplicateTokenEx and   CreateProcessAsUser
// I would prefer to not have to use a security attribute variable and to just 
// simply pass null and inherit (by default) the security attributes
// of the existing token. However, in C# structures are value types and   therefore
// cannot be assigned the null value.
SECURITY_ATTRIBUTES sa = new SECURITY_ATTRIBUTES();
sa.Length = Marshal.SizeOf(sa);

// copy the access token of the winlogon process; 
// the newly created token will be a primary token
if (!DuplicateTokenEx(hPToken, MAXIMUM_ALLOWED, ref sa, 
    (int)SECURITY_IMPERSONATION_LEVEL.SecurityIdentification, 
    (int)TOKEN_TYPE.TokenPrimary, ref hUserTokenDup))
    {
      CloseHandle(hProcess);
      CloseHandle(hPToken);
      return false;
    }

 STARTUPINFO si = new STARTUPINFO();
 si.cb = (int)Marshal.SizeOf(si);

// interactive window station parameter; basically this indicates 
// that the process created can display a GUI on the desktop
si.lpDesktop = @"winsta0\default";

// flags that specify the priority and creation method of the process
int dwCreationFlags = NORMAL_PRIORITY_CLASS | CREATE_NEW_CONSOLE;

// create a new process in the current User's logon session
 bool result = CreateProcessAsUser(hUserTokenDup,  // client's access token
                            null,             // file to execute
                            applicationName,  // command line
                            ref sa,           // pointer to process    SECURITY_ATTRIBUTES
                            ref sa,           // pointer to thread SECURITY_ATTRIBUTES
                            false,            // handles are not inheritable
                            dwCreationFlags,  // creation flags
                            IntPtr.Zero,      // pointer to new environment block 
                            null,             // name of current directory 
                            ref si,           // pointer to STARTUPINFO structure
                            out procInfo      // receives information about new process
                            );

Although there is nothing wrong with the other solutions presented, you could simplify and greatly escalate your solutions by using python's excellent library pandas.

Pandas is a library for handling data in Python, preferred by many Data Scientists.

Pandas has a simplified CSV interface to read and parse files, that can be used to return a list of dictionaries, each containing a single line of the file. The keys will be the column names, and the values will be the ones in each cell.

In your case:

    import pandas

    def create_dictionary(filename):
        my_data = pandas.DataFrame.from_csv(filename, sep='\t', index_col=False)
        # Here you can delete the dataframe columns you don't want!
        del my_data['B']
        del my_data['D']
        # ...
        # Now you transform the DataFrame to a list of dictionaries
        list_of_dicts = [item for item in my_data.T.to_dict().values()]
        return list_of_dicts

# Usage:
x = create_dictionary("myfile.csv")

I agree with the Hamed elahi and Glorfindel.

My suggestion to add is you can delete and update using aliases

/* 
  given a table bi_customer_actions
  with a field bca_delete_flag of tinyint or bit
    and a field bca_add_date of datetime

  note: the *if 1=1* structure allows me to fold them and turn them on and off
 */
declare
        @Nrows int = 1000

if 1=1 /* testing the inner select */
begin
  select top (@Nrows) * 
    from bi_customer_actions
    where bca_delete_flag = 1
    order by bca_add_date
end

if 1=1 /* delete or update or select */
begin
  --select bca.*
  --update bca  set bca_delete_flag = 0
  delete bca
    from (
      select top (@Nrows) * 
        from bi_customer_actions
        where bca_delete_flag = 1
        order by bca_add_date
    ) as bca
end 

I ran into this when checking on a null or empty string

if (x == NULL || x == '') {

changed it to

if (is.null(x) || x == '') {

In order to read a file chosen by the user, using a file open dialog, you can use the <input type="file"> tag. You can find information on it from MSDN. When the file is chosen you can use the FileReader API to read the contents.

function onFileLoad(elementId, event) {_x000D_
    document.getElementById(elementId).innerText = event.target.result;_x000D_
}_x000D_
_x000D_
function onChooseFile(event, onLoadFileHandler) {_x000D_
    if (typeof window.FileReader !== 'function')_x000D_
        throw ("The file API isn't supported on this browser.");_x000D_
    let input = event.target;_x000D_
    if (!input)_x000D_
        throw ("The browser does not properly implement the event object");_x000D_
    if (!input.files)_x000D_
        throw ("This browser does not support the `files` property of the file input.");_x000D_
    if (!input.files[0])_x000D_
        return undefined;_x000D_
    let file = input.files[0];_x000D_
    let fr = new FileReader();_x000D_
    fr.onload = onLoadFileHandler;_x000D_
    fr.readAsText(file);_x000D_
}

<input type='file' onchange='onChooseFile(event, onFileLoad.bind(this, "contents"))' />_x000D_
<p id="contents"></p>

If you only care about html5 browsers you can use error event (since this is only for error handling, it should be ok to only support this on next gen browsers for KISS IMHO).

From the spec:

If the src attribute's value is the empty string or if it could not be resolved, then the user agent must queue a task to fire a simple event named error at the element, and abort these steps.

~

If the load resulted in an error (for example a DNS error, or an HTTP 404 error) Executing the script block must just consist of firing a simple event named error at the element.

This means you don't have to do any error prone polling and can combine it with async and defer attribute to make sure the script is not blocking page rendering:

The defer attribute may be specified even if the async attribute is specified, to cause legacy Web browsers that only support defer (and not async) to fall back to the defer behavior instead of the synchronous blocking behavior that is the default.

As an addition to the answer of @mavroprovato, if you want to trust all certificates instead of just self-signed, you'd do (in the style of your code)

builder.loadTrustMaterial(null, new TrustStrategy(){
    public boolean isTrusted(X509Certificate[] chain, String authType)
        throws CertificateException {
        return true;
    }
});

or (direct copy-paste from my own code):

import javax.net.ssl.SSLContext;
import org.apache.http.ssl.TrustStrategy;
import org.apache.http.ssl.SSLContexts;

// ...

        SSLContext sslContext = SSLContexts
                .custom()
                //FIXME to contain real trust store
                .loadTrustMaterial(new TrustStrategy() {
                    @Override
                    public boolean isTrusted(X509Certificate[] chain,
                        String authType) throws CertificateException {
                        return true;
                    }
                })
                .build();

And if you want to skip hostname verification as well, you need to set

    CloseableHttpClient httpclient = HttpClients.custom().setSSLSocketFactory(
            sslsf).setSSLHostnameVerifier( NoopHostnameVerifier.INSTANCE).build();

as well. (ALLOW_ALL_HOSTNAME_VERIFIER is deprecated).

Obligatory warning: you shouldn't really do this, accepting all certificates is a bad thing. However there are some rare use cases where you want to do this.

As a note to code previously given, you'll want to close response even if httpclient.execute() throws an exception

CloseableHttpResponse response = null;
try {
    response = httpclient.execute(httpGet);
    System.out.println(response.getStatusLine());
    HttpEntity entity = response.getEntity();
    EntityUtils.consume(entity);
}
finally {
    if (response != null) {
        response.close();
    }
}

I mostly use following code to scroll down

$('html, body').animate({ scrollTop:  $(SELECTOR).offset().top - 50 }, 'slow');

As discussed in the comments, this can be achieved by converting the entry into Date format and extracting the year, for instance like this:

format(as.Date(df1$Date, format="%d/%m/%Y"),"%Y")

Basically we had to enable TLS 1.2 for .NET 4.x. Making this registry changed worked for me, and stopped the event log filling up with the Schannel error.

More information on the answer can be found here

Linked Info Summary

Enable TLS 1.2 at the system (SCHANNEL) level:

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2]
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Client]
"DisabledByDefault"=dword:00000000
"Enabled"=dword:00000001
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Server]
"DisabledByDefault"=dword:00000000
"Enabled"=dword:00000001

(equivalent keys are probably also available for other TLS versions)

Tell .NET Framework to use the system TLS versions:

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v4.0.30319]
"SystemDefaultTlsVersions"=dword:00000001
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\.NETFramework\v4.0.30319]
"SystemDefaultTlsVersions"=dword:00000001

This may not be desirable for edge cases where .NET Framework 4.x applications need to have different protocols enabled and disabled than the OS does.

      $sql = "INSERT into prod_list_1(p_bench,p_name,p_price,p_reason) values ('$emapData[0]','$emapData[1]','$emapData[2]','$emapData[3]')";
      mysql_query($sql);
    }                                              // add this line
}

I tried this, but the query won't run telling me my field is invalid in the select statement because it is not contained in either an aggregate function or the GROUP BY clause. It's forcing me to keep it there. Is there a way around this?

You need to do a self-join. You can't both aggregate and preserve non-aggregated data in the same subquery. E.g.

select q2.AccountNumber, q2.Bill, q2.BillDate, q1.BillSum
from
(
SELECT AccountNumber, SUM(Bill) as BillSum
FROM Table1
GROUP BY AccountNumber
) q1,
(
select AccountNumber, Bill, BillDate
from table1
) q2
where q1.AccountNumber = q2.AccountNumber

You can use scipy, which is pretty straight forward:

scipy.misc.derivative(func, x0, dx=1.0, n=1, args=(), order=3)

Find the nth derivative of a function at a point.

In your case:

from scipy.misc import derivative

def f(x):
    return x**2 + 1

derivative(f, 5, dx=1e-6)
# 10.00000000139778

Try

//book[title/@lang = 'it']

This reads:

• get all book elements
  • that have at least one title
    • which has an attribute lang
      • with a value of "it"

You may find this helpful — it's an article entitled "XPath in Five Paragraphs" by Ronald Bourret.

But in all honesty, //book[title[@lang='it']] and the above should be equivalent, unless your XPath engine has "issues." So it could be something in the code or sample XML that you're not showing us -- for example, your sample is an XML fragment. Could it be that the root element has a namespace, and you aren't counting for that in your query? And you only told us that it didn't work, but you didn't tell us what results you did get.

>>> [int(i) for i in str(12345)]

[1, 2, 3, 4, 5]

It's work for Iphone

<?php
  $browser = strpos($_SERVER['HTTP_USER_AGENT'],"iPhone");
  if ($browser == true){
    $browser = 'iphone';
  }
?>

Using set and the /p parameter you can echo without newline:

C:\> echo Hello World
Hello World

C:\> echo|set /p="Hello World"
Hello World
C:\>

sys.exit() raises a SystemExit exception which you are probably assuming as some error. If you want your program not to raise SystemExit but return gracefully, you can wrap your functionality in a function and return from places you are planning to use sys.exit

  #!/bin.bash
for folder_to_go in $(find . -mindepth 1 -maxdepth 1 -type d \( -name "*" \) ) ; 
                                    # you can add pattern insted of * , here it goes to any folder 
                                    #-mindepth / maxdepth 1 means one folder depth   
do
cd $folder_to_go
  echo $folder_to_go "########################################## "
  
  whatever you want to do is here

cd ../ # if maxdepth/mindepath = 2,  cd ../../
done

#you can try adding many internal for loops with many patterns, this will sneak anywhere you want

The method never returns because it's the end of the world and none of your code is going to be executed next.

Your application, in your example, would exit anyway at the same spot in the code, but, if you use System.exit. you have the option of returning a custom code to the enviroment, like, say

System.exit(42);

Who is going to make use of your exit code? A script that called the application. Works in Windows, Unix and all other scriptable environments.

Why return a code? To say things like "I did not succeed", "The database did not answer".

To see how to get the value od an exit code and use it in a unix shell script or windows cmd script, you might check this answer on this site

For me the issue was the configuration was set to a custom AsLive instead of Debug.

Setting that back sorted it for me.

public int countOfOccurrences(String str, String subStr) {
  return (str.length() - str.replaceAll(Pattern.quote(subStr), "").length()) / subStr.length();
}

Assume your project folder structure as follows :

c:\test\classes\com\test\awt\Example.class

c:\test\classes\manifest.txt

You can issue following command to create a “Example.jar.

jar -cvfm Example.jar manifest.txt com/test/awt/*.class

For Example :

go to folder structure from commmand prompt "cd C:\test\classes"

C:\test\classes>jar -cvfm Example.jar manifest.txt com/test/awt/*.class

It can be done and with rather simple php if this is your button

<input type="submit" name="submit>

and this is your php code

if(isset($_POST["submit"])) { php code here }

the code get's called when submit get's posted which happens when the button is clicked.

Building on this question, I use the following code to indent my messages:

String prefix1 = "short text:";
String prefix2 = "looooooooooooooong text:";
String msg = "indented";
/*
* The second string begins after 40 characters. The dash means that the
* first string is left-justified.
*/
String format = "%-40s%s%n";
System.out.printf(format, prefix1, msg);
System.out.printf(format, prefix2, msg);

This is the output:

short text:                             indented
looooooooooooooong text:                indented

This is documented in section "Flag characters" in man 3 printf.

Do use this:

highp float rand(vec2 co)
{
    highp float a = 12.9898;
    highp float b = 78.233;
    highp float c = 43758.5453;
    highp float dt= dot(co.xy ,vec2(a,b));
    highp float sn= mod(dt,3.14);
    return fract(sin(sn) * c);
}

Don't use this:

float rand(vec2 co){
    return fract(sin(dot(co.xy ,vec2(12.9898,78.233))) * 43758.5453);
}

You can find the explanation in Improvements to the canonical one-liner GLSL rand() for OpenGL ES 2.0

Can you try this:

select convert(nvarchar(max),convert(varbinary(max),blob_column)) from table_name

Of course you can, say for example, you want to use the DescriptionAttribue on your enum values:

using System.ComponentModel.DataAnnotations;

public enum Duration 
{ 
    [Description("Eight hours")]
    Day,

    [Description("Five days")]
    Week,

    [Description("Twenty-one days")] 
    Month 
}

Now you want to be able to do something like:

Duration duration = Duration.Week;
var description = duration.GetDescription(); // will return "Five days"

Your extension method GetDescription() can be written as follows:

using System.ComponentModel;
using System.Reflection;

public static string GetDescription(this Enum value)
{
    FieldInfo fieldInfo = value.GetType().GetField(value.ToString());
    if (fieldInfo == null) return null;
    var attribute = (DescriptionAttribute)fieldInfo.GetCustomAttribute(typeof(DescriptionAttribute));
    return attribute.Description;
}

You can simply return if you want to skip the current iteration.

Since you're in a function, if you return before doing anything else, then you have effectively skipped execution of the code below the return statement.

There are 3 basic commands to compare files in unix:

1. cmp : This command is used to compare two files byte by byte and as any mismatch occurs,it echoes it on the screen.if no mismatch occurs i gives no response. syntax:$cmp file1 file2.

2. comm : This command is used to find out the records available in one but not in another

3. diff

I think it is in fact desirable to have sudo reset the PATH: otherwise an attacker having compromised your user account could put backdoored versions of all kinds of tools on your users' PATH, and they would be executed when using sudo.

(of course having sudo reset the PATH is not a complete solution to these kinds of problems, but it helps)

This is indeed what happens when you use

Defaults env_reset

in /etc/sudoers without using exempt_group or env_keep.

This is also convenient because you can add directories that are only useful for root (such as /sbin and /usr/sbin) to the sudo path without adding them to your users' paths. To specify the path to be used by sudo:

Defaults secure_path="/bin:/usr/bin:/usr/local/bin:/sbin:/usr/sbin"

With the global configuration that you have defined for the exec-maven-plugin:

<plugin>
  <groupId>org.codehaus.mojo</groupId>
  <artifactId>exec-maven-plugin</artifactId>
  <version>1.4.0</version>
  <configuration>
    <mainClass>org.dhappy.test.NeoTraverse</mainClass>
  </configuration>
</plugin>

invoking mvn exec:java on the command line will invoke the plugin which is configured to execute the class org.dhappy.test.NeoTraverse.

So, to trigger the plugin from the command line, just run:

mvn exec:java

Now, if you want to execute the exec:java goal as part of your standard build, you'll need to bind the goal to a particular phase of the default lifecycle. To do this, declare the phase to which you want to bind the goal in the execution element:

<plugin>
  <groupId>org.codehaus.mojo</groupId>
  <artifactId>exec-maven-plugin</artifactId>
  <version>1.4</version>
  <executions>
    <execution>
      <id>my-execution</id>
      <phase>package</phase>
      <goals>
        <goal>java</goal>
      </goals>
    </execution>
  </executions>
  <configuration>
    <mainClass>org.dhappy.test.NeoTraverse</mainClass>
  </configuration>
</plugin>

With this example, your class would be executed during the package phase. This is just an example, adapt it to suit your needs. Works also with plugin version 1.1.

You can also change the value of this database parameter for your session by using the ALTER SESSION command and use it as you wanted

ALTER SESSION SET NLS_DATE_FORMAT = 'DD-MM-YYYY';
SELECT TO_DATE('05-12-2015') FROM dual;

05/12/2015

You can use the net send command to send a message over a network.

example:

net send * How Are You

you can use the above statement to send a message to all members of your domain.But if you want to send a message to a single user named Mike, you can use

 net send mike hello!

this will send hello! to the user named Mike.

In file /etc/ssh/sshd_config

# Change to no to disable tunnelled clear text passwords
#PasswordAuthentication no

Uncomment the second line, and, if needed, change yes to no.

Then run

service ssh restart

The only way of having a variable which hasn't been assigned a value in C# is for it to be a local variable - in which case at compile-time you can tell that it isn't definitely assigned by trying to read from it :)

I suspect you really want Nullable<DateTime> (or DateTime? with the C# syntactic sugar) - make it null to start with and then assign a normal DateTime value (which will be converted appropriately). Then you can just compare with null (or use the HasValue property) to see whether a "real" value has been set.

(Three years late...) but I believe the answer to your second question is that SSRS essentially treats data from your datasets as unsorted; I'm not sure if it ignores any ORDER BY in the sql, or if it just assumes the data is unsorted.

To sort your groups in a particular order, you need to specify it in the report:

• Select the chart,
• In the Chart Data popup window (where you specify the Category Groups), right-click your Group and click Category Group Properties,
• Click on the Sorting option to see a control to set the Sort order

For the report I just created, the default sort order on the category was alphabetic on the category group which was basically a string code. But sometimes it can be useful to sort by some other characteristic of the data; for example, my report is of Average and Maximum processing times for messages identified by some code (the category). By setting the sort order of the group to be on [MaxElapsedMs], Z->A it draws my attention to the worst-performing message-types.

This sort of presentation won't be useful for every report but it can be an excellent tool to guide readers to have a better understanding of the data; though on other occasions you might prefer a report to have the same ordering every time it runs, in which case sorting on the category label itself may be best... and I guess there are circumstances where changing the sort order could harm understanding, such as if the categories implied some sort of ordering (such as date values?)

RMDIR path_to_folder /S

ex. RMDIR "C:\tmp" /S

Note that you'll be prompted if you're really going to delete the "C:\tmp" folder. Combining it with /Q switch will remove the folder silently (ex. RMDIR "C:\tmp" /S /Q)

OR condition in #ifdef

#if defined LINUX || defined ANDROID
// your code here
#endif /* LINUX || ANDROID */

or-

#if defined(LINUX) || defined(ANDROID)
// your code here
#endif /* LINUX || ANDROID */

Both above are the same, which one you use simply depends on your taste.

P.S.: #ifdef is simply the short form of #if defined, however, does not support complex condition.

Further-

• AND: #if defined LINUX && defined ANDROID
• XOR: #if defined LINUX ^ defined ANDROID

The following code outputs the number of words whose first and last letters are equal. Tested and verified using a python online compiler:

words = ['aba', 'xyz', 'xgx', 'dssd', 'sdjh']  
count = 0  
for i in words:  
     if i[0]==i[-1]:
        count = count + 1  
print(count)  

Output:

$python main.py

Here is my option to Edit the project file without the need to Unload the project:

1. Open Solution Explorer and switch to folder view:

2. Navigate to the Project which you want to edit inside the Solution folders and right-click on it.

3. Choose Open from the Context Menu.

That is it!

You will see the *.csproj file opened inside Visual Studio Editor.
After you can switch back to a Solution/Project view (see step 1).

High-Level Design (HLD) involves decomposing a system into modules, and representing the interfaces & invocation relationships among modules. An HLD is referred to as software architecture.

LLD, also known as a detailed design, is used to design internals of the individual modules identified during HLD i.e. data structures and algorithms of the modules are designed and documented.

Now, HLD and LLD are actually used in traditional Approach (Function-Oriented Software Design) whereas, in OOAD, the system is seen as a set of objects interacting with each other.

As per the above definitions, a high-level design document will usually include a high-level architecture diagram depicting the components, interfaces, and networks that need to be further specified or developed. The document may also depict or otherwise refer to work flows and/or data flows between component systems.

Class diagrams with all the methods and relations between classes come under LLD. Program specs are covered under LLD. LLD describes each and every module in an elaborate manner so that the programmer can directly code the program based on it. There will be at least 1 document for each module. The LLD will contain - a detailed functional logic of the module in pseudo code - database tables with all elements including their type and size - all interface details with complete API references(both requests and responses) - all dependency issues - error message listings - complete inputs and outputs for a module.

Rather than placing an extra scanner.nextLine() each time you want to read something, since it seems you want to accept each input on a new line, you might want to instead changing the delimiter to actually match only newlines (instead of any whitespace, as is the default)

import java.util.Scanner;

class ScannerTest {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        scanner.useDelimiter("\\n");

        System.out.print("Enter an index: ");
        int index = scanner.nextInt();

        System.out.print("Enter a sentence: ");
        String sentence = scanner.next();

        System.out.println("\nYour sentence: " + sentence);
        System.out.println("Your index: " + index);
    }
}

Thus, to read a line of input, you only need scanner.next() that has the same behavior delimiter-wise of next{Int, Double, ...}

The difference with the "nextLine() every time" approach, is that the latter will accept, as an index also <space>3, 3<space> and 3<space>whatever while the former only accepts 3 on a line on its own

Premise to my answer:

1. Containers are run with tags.
2. The same tag can be pointed to different image UUID as we please/ feel appropriate.
3. Updates done to an image can be committed to a new image layer

Approach

1. Build all the containers in the first place with a security-patch update script
2. Build an automated process for the following
   • Run an existing image to new container with security patch script as the command
   • Commit changes to the image as
     • existing tag -> followed by restarting the containers one by one
     • new version tag -> replace few containers with new tag -> validate -> move all containers to new tag

Additionally, the base image can be upgraded/ the container with a complete new base image can be built at regular intervals, as the maintainer feels necessary

Advantages

1. We are preserving the old version of the image while creating the new security patched image, hence we can rollback to previous running image if necessary
2. We are preserving the docker cache, hence less network transfer (only the changed layer gets on the wire)
3. The upgrade process can be validated in staging before moving to prod
4. This can be a controlled process, hence the security patches only when necessary/ deemed important can be pushed.

Are you looking for behavior similar to the x that shows up on the right side of text fields on an iphone that clears the text when tapped? It's called clearButtonMode there. Here is how to create that same functionality in an Android EditText view:

String value = "";//any text you are pre-filling in the EditText

final EditText et = new EditText(this);
et.setText(value);
final Drawable x = getResources().getDrawable(R.drawable.presence_offline);//your x image, this one from standard android images looks pretty good actually
x.setBounds(0, 0, x.getIntrinsicWidth(), x.getIntrinsicHeight());
et.setCompoundDrawables(null, null, value.equals("") ? null : x, null);
et.setOnTouchListener(new OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {
        if (et.getCompoundDrawables()[2] == null) {
            return false;
        }
        if (event.getAction() != MotionEvent.ACTION_UP) {
            return false;
        }
        if (event.getX() > et.getWidth() - et.getPaddingRight() - x.getIntrinsicWidth()) {
            et.setText("");
            et.setCompoundDrawables(null, null, null, null);
        }
        return false;
    }
});
et.addTextChangedListener(new TextWatcher() {
    @Override
    public void onTextChanged(CharSequence s, int start, int before, int count) {
        et.setCompoundDrawables(null, null, et.getText().toString().equals("") ? null : x, null);
    }

    @Override
    public void afterTextChanged(Editable arg0) {
    }

    @Override
    public void beforeTextChanged(CharSequence s, int start, int count, int after) {
    }
});

OMG!!! YES, WE CAN DO THAT!!! I was going to kill myself after severe 24 hours of investigating and discovering... But I've found "fresh" solution!

// "cheat" with Java reflection to gain access to TelephonyManager's
// ITelephony getter
Class c = Class.forName(tm.getClass().getName());
Method m = c.getDeclaredMethod("getITelephony");
m.setAccessible(true);
telephonyService = (ITelephony)m.invoke(tm);

all all all of hundreds of people who wants to develop their call-control software visit this start point

there is a project. and there are important comments (and credits)

briefly: copy aidl file, add permissions to manifest, copy-paste source for telephony management )))

Some more info for you. AT commands you can send only if you are rooted. Than you can kill system process and send commands but you will need a reboot to allow your phone to receive and send calls =)))

I'm very hapy =) Now my Shake2MuteCall will get an update !

You can just substract two date objects.

var d1 = new Date(); //"now"
var d2 = new Date("2011/02/01")  // some date
var diff = Math.abs(d1-d2);  // difference in milliseconds

if (x & 1)
 itIsOddNumber();
else
 itIsEvenNumber();

In about:config add content.cors.disable (empty string).

In additional to the popular K8s, jasypt or vault solutions, there's also Karmahostage. It enables you to do:

@EncryptedValue("${application.secret}")
private String application;

It works the same way jasypt does, but encryption happens on a dedicated saas solution, with a more fine-grained ACL model attached to it.

If this is ASP.net-Core then you are mixing web API versions. Have the action return a derived IActionResult because in your current code the framework is treating HttpResponseMessage as a model.

[Route("api/[controller]")]
public class DownloadController : Controller {
    //GET api/download/12345abc
    [HttpGet("{id}"]
    public async Task<IActionResult> Download(string id) {
        Stream stream = await {{__get_stream_based_on_id_here__}}

        if(stream == null)
            return NotFound(); // returns a NotFoundResult with Status404NotFound response.

        return File(stream, "application/octet-stream"); // returns a FileStreamResult
    }    
}

Show the title before the loop starts:

$page_title = $wp_query->post->post_title;

I have put this working code snippet for future references. The code sample was written with Apache velocity version 1.7 with embedded Jetty.

Velocity template path is located at the resource folder email_templates subfolder.

Code Snippet in Java (Snippets are worked both running on eclipse and inside a Jar)

    templateName = "/email_templates/byoa.tpl.vm"
    VelocityEngine ve = new VelocityEngine();
    ve.setProperty(RuntimeConstants.RESOURCE_LOADER, "classpath");
    ve.setProperty("classpath.resource.loader.class", ClasspathResourceLoader.class.getName());
    ve.init();
    Template t = ve.getTemplate(this.templateName);
    VelocityContext velocityContext = new VelocityContext();
    velocityContext.put("","") // put your template values here
    StringWriter writer = new StringWriter();
    t.merge(this.velocityContext, writer);

System.out.println(writer.toString()); // print the updated template as string

For OSGI plugging code snippets.

final String TEMPLATE = "resources/template.vm" // located in the resources folder
Thread current = Thread.currentThread();
       ClassLoader oldLoader = current.getContextClassLoader();
       try {
          current.setContextClassLoader(TemplateHelper.class.getClassLoader()); // TemplateHelper is a class inside your jar file
          Properties p = new Properties();
          p.setProperty("resource.loader", "class");
          p.setProperty("class.resource.loader.class", "org.apache.velocity.runtime.resource.loader.ClasspathResourceLoader");
          Velocity.init( p );       
          VelocityEngine ve = new VelocityEngine();
          Template template = Velocity.getTemplate( TEMPLATE );
          VelocityContext context = new VelocityContext();
          context.put("tc", obj);
          StringWriter writer = new StringWriter();
          template.merge( context, writer );
          return writer.toString() ;  
       }  catch(Exception e){
          e.printStackTrace();
       } finally {
          current.setContextClassLoader(oldLoader);
       }

I'd suggest OOWeb to act as an HTTP server and a templating engine like Velocity to generate HTML. I also second Esko's suggestion of Wicket. Both solutions are considerably simpler than the average setup.

You can throw an unchecked exception from the method which you wish to roll back. This will be detected by spring and your transaction will be marked as rollback only.

I'm assuming you're using Spring here. And I assume the annotations you refer to in your tests are the spring test based annotations.

The recommended way to indicate to the Spring Framework's transaction infrastructure that a transaction's work is to be rolled back is to throw an Exception from code that is currently executing in the context of a transaction.

and note that:

please note that the Spring Framework's transaction infrastructure code will, by default, only mark a transaction for rollback in the case of runtime, unchecked exceptions; that is, when the thrown exception is an instance or subclass of RuntimeException.

The above solution works perfectly. I prefer to choose Web API option while selecting the project template as shown in the picture below

Note: The solution works with Visual Studio 2013 or higher. The original question was asked in 2012 and it is 2016, therefore adding a solution Visual Studio 2013 or higher.

Unless the variable k is defined, that's probably what's causing your trouble. Something like this will do what you want:

var new_tweets = { };

new_tweets.k = { };

new_tweets.k.tweet_id = 98745521;
new_tweets.k.user_id = 54875;

new_tweets.k.data = { };

new_tweets.k.data.in_reply_to_screen_name = 'other_user';
new_tweets.k.data.text = 'tweet text';

// Will create the JSON string you're looking for.
var json = JSON.stringify(new_tweets);

You can also do it all at once:

var new_tweets = {
  k: {
    tweet_id: 98745521,
    user_id: 54875,
    data: {
      in_reply_to_screen_name: 'other_user',
      text: 'tweet_text'
    }
  }
}

Use the -I flag to gcc properly.

gcc -I/path/to/openssl/ -o Opentest -lcrypto Opentest.c

The -I should point to the directory containing the openssl folder.

If it helps there is also a jar-versions.xml in my JBoss installation in JBoss root folder. This doesn't require you to wget or jar xvf.

E.g.

$  grep jboss-system.jar /opt/jboss-5.1.0.GA/jar-versions.xml | fold

1. declarations: This property tells about the Components, Directives and Pipes that belong to this module.
2. exports: The subset of declarations that should be visible and usable in the component templates of other NgModules.
3. imports: Other modules whose exported classes are needed by component templates declared in this NgModule.
4. providers: Creators of services that this NgModule contributes to the global collection of services; they become accessible in all parts of the app. (You can also specify providers at the component level, which is often preferred.)
5. bootstrap: The main application view, called the root component, which hosts all other app views. Only the root NgModule should set the bootstrap property.

Elaborating on this answer and this answer.

Above answers point out the problem of many of the solutions here which don't iterate by code point value -- they would have trouble with any surrogate chars. The java docs also outline the issue here (see "Unicode Character Representations"). Anyhow, here's some code that uses some actual surrogate chars from the supplementary Unicode set, and converts them back to a String. Note that .toChars() returns an array of chars: if you're dealing with surrogates, you'll necessarily have two chars. This code should work for any Unicode character.

    String supplementary = "Some Supplementary: ";
    supplementary.codePoints().forEach(cp -> 
            System.out.print(new String(Character.toChars(cp))));

ADD go /usr/local/

will copy the contents of your local go directory in the /usr/local/ directory of your docker image.

To copy the go directory itself in /usr/local/ use:

ADD go /usr/local/go

or

COPY go /usr/local/go

You should not rely on a hash code being equal to a specific value. Just that it will return consistent results within the same execution. The API docs say the following :

The general contract of hashCode is:

• Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.

EDIT Since the javadoc for String.hashCode() specifies how a String's hash code is computed, any violation of this would violate the public API specification.

please Press fn +ins key together

For references you can call

rails generate migration AddUserIdColumnToTable user:references

If in the future you need to add a general index you can launch this

rails g migration AddOrdinationNumberToTable ordination_number:integer:index

Generate code:

class AddOrdinationNumberToTable < ActiveRecord::Migration
  def change
   add_column :tables, :ordination_number, :integer
   add_index :tables, :ordination_number, unique: true
  end
end

Now an uppercase and lowercase switch can be done simultaneously in the selected strings via a regular expression replacement (regex, CtrlH + AltR), according to v1.47.3 June 2020 release:

This is done through 4 "Single character" character classes (Perl documentation), namely, for the matched group following it:

• \l <=> [[:lower:]]: first character becomes lowercase
• \u <=> [[:upper:]]: first character becomes uppercase
• \L <=> [^[:lower:]]: all characters become lowercase
• \U <=> [^[:upper:]]: all characters become uppercase

$0 matches all selected groups, while $1 matches the 1st group, $2 the 2nd one, etc.

Hit the Match Case button at the left of the search bar (or AltC) and, borrowing some examples from an old Sublime Text answer, now this is possible:

1. Capitalize words

• Find: (\s)([a-z]) (\s matches spaces and new lines, i.e. " venuS" => " VenuS")
• Replace: $1\u$2

2. Uncapitalize words

• Find: (\s)([A-Z])
• Replace: $1\l$2

3. Remove a single camel case (e.g. cAmelCAse => camelcAse => camelcase)

• Find: ([a-z])([A-Z])
• Replace: $1\l$2

4. Lowercase all from an uppercase letter within words (e.g. LowerCASe => Lowercase)

• Find: (\w)([A-Z]+)
• Replace: $1\L$2
• Alternate Replace: \L$0

5. Uppercase all from a lowercase letter within words (e.g. upperCASe => uPPERCASE)

• Find: (\w)([A-Z]+)
• Replace: $1\U$2

6. Uppercase previous (e.g. upperCase => UPPERCase)

• Find: (\w+)([A-Z])
• Replace: \U$1$2

7. Lowercase previous (e.g. LOWERCase => lowerCase)

• Find: (\w+)([A-Z])
• Replace: \L$1$2

8. Uppercase the rest (e.g. upperCase => upperCASE)

• Find: ([A-Z])(\w+)
• Replace: $1\U$2

9. Lowercase the rest (e.g. lOWERCASE => lOwercase)

• Find: ([A-Z])(\w+)
• Replace: $1\L$2

10. Shift-right-uppercase (e.g. Case => cAse => caSe => casE)

• Find: ([a-z\s])([A-Z])(\w)
• Replace: $1\l$2\u$3

11. Shift-left-uppercase (e.g. CasE => CaSe => CAse => Case)

• Find: (\w)([A-Z])([a-z\s])
• Replace: \u$1\l$2$3

This happened to me, i found it was caused by some cache files which were invalid. so i disabled cache by adding

android.enableBuildCache=false

to gradle properties.

You need to start the SQL Server manually. Press

windows + R

type

sqlservermanager12.msc

right click ->Start

Service configuration does not display SQL Server?

Below command worked out pretty good:

javac -version

I also manually verified by navigating to the Java Folder on my Mac

/Library/Java/JavaVirtualMachines/jdk1.8.0_131.jdk

With the release of Mercurial 2.2, you can use the --amend option with hg commit to update the last commit with the current working directory

From the command line reference:

The --amend flag can be used to amend the parent of the working directory with a new commit that contains the changes in the parent in addition to those currently reported by hg status, if there are any. The old commit is stored in a backup bundle in .hg/strip-backup (see hg help bundle and hg help unbundle on how to restore it).

Message, user and date are taken from the amended commit unless specified. When a message isn't specified on the command line, the editor will open with the message of the amended commit.

The great thing is that this mechanism is "safe", because it relies on the relatively new "Phases" feature to prevent updates that would change history that's already been made available outside of the local repository.

You can escape the calc arguments in order to prevent them from being evaluated on compilation.

Using your example, you would simply surround the arguments, like this:

calc(~'100% - 10px')

Demo : http://jsfiddle.net/c5aq20b6/

I find that I use this in one of the following three ways:

Basic Escaping

Everything inside the calc arguments is defined as a string, and is totally static until it's evaluated by the client:

LESS Input

div {
    > span {
        width: calc(~'100% - 10px');
    }
}

CSS Output

div > span {
  width: calc(100% - 10px);
}

Interpolation of Variables

You can insert a LESS variable into the string:

LESS Input

div {
    > span {
        @pad: 10px;
        width: calc(~'100% - @{pad}');
    }
}

CSS Output

div > span {
  width: calc(100% - 10px);
}

Mixing Escaped and Compiled Values

You may want to escape a percentage value, but go ahead and evaluate something on compilation:

LESS Input

@btnWidth: 40px;
div {
    > span {
        @pad: 10px;
        width: calc(~'(100% - @{pad})' - (@btnWidth * 2));
    }
}

CSS Output

div > span {
  width: calc((100% - 10px) - 80px);
}

When you build your assembly, you can call AssemblyBuilder.SetEntryPoint, and then get it back from the Assembly.EntryPoint property to invoke it.

Keep in mind you'll want to use this signature, and note that it doesn't have to be named Main:

static void Run(string[] args)

The way I handled this was switching the className of a label based on a condition. This way you only need one label and you can have different classes for different states... Hope that helps!

Use timer.scheduleAtFixedRate

public void scheduleAtFixedRate(TimerTask task,
                                long delay,
                                long period)

Schedules the specified task for repeated fixed-rate execution, beginning after the specified delay. Subsequent executions take place at approximately regular intervals, separated by the specified period.
In fixed-rate execution, each execution is scheduled relative to the scheduled execution time of the initial execution. If an execution is delayed for any reason (such as garbage collection or other background activity), two or more executions will occur in rapid succession to "catch up." In the long run, the frequency of execution will be exactly the reciprocal of the specified period (assuming the system clock underlying Object.wait(long) is accurate).

Fixed-rate execution is appropriate for recurring activities that are sensitive to absolute time, such as ringing a chime every hour on the hour, or running scheduled maintenance every day at a particular time. It is also appropriate for recurring activities where the total time to perform a fixed number of executions is important, such as a countdown timer that ticks once every second for ten seconds. Finally, fixed-rate execution is appropriate for scheduling multiple repeating timer tasks that must remain synchronized with respect to one another.

Parameters:

• task - task to be scheduled.
• delay - delay in milliseconds before task is to be executed.
• period - time in milliseconds between successive task executions.

Throws:

• IllegalArgumentException - if delay is negative, or delay + System.currentTimeMillis() is negative.
• IllegalStateException - if task was already scheduled or cancelled, timer was cancelled, or timer thread terminated.

Document
Document style messages can be validated against predefined schema. In document style, SOAP message is sent as a single document. Example of schema:

  <types>  
   <xsd:schema> <xsd:import namespace="http://example.com/" 
    schemaLocation="http://localhost:8080/ws/hello?xsd=1"/>  
   </xsd:schema>  
  </types>

Example of document style soap body message

  <message name="getHelloWorldAsString">   
     <part name="parameters" element="tns:getHelloWorldAsString"/>   
  </message> 
  <message name="getHelloWorldAsStringResponse">  
     <part name="parameters"> element="tns:getHelloWorldAsStringResponse"/>   
  </message>

Document style message is loosely coupled.

RPC RPC style messages use method name and parameters to generate XML structure. messages are difficult to be validated against schema. In RPC style, SOAP message is sent as many elements.

  <message name="getHelloWorldAsString">
    <part name="arg0"> type="xsd:string"/>   
   </message> 
  <message name="getHelloWorldAsStringResponse">   
    <part name="return"
   > type="xsd:string"/>   
  </message>

Here each parameters are discretely specified, RPC style message is tightly coupled, is typically static, requiring changes to the client when the method signature changes The rpc style is limited to very simple XSD types such as String and Integer, and the resulting WSDL will not even have a types section to define and constrain the parameters

Literal By default style. Data is serialized according to a schema, data type not specified in messages but a reference to schema(namespace) is used to build soap messages.

   <soap:body>
     <myMethod>
        <x>5</x>
        <y>5.0</y>
     </myMethod>
   </soap:body>

Encoded Datatype specified in each parameter

   <soap:body>
     <myMethod>
         <x xsi:type="xsd:int">5</x>
         <y xsi:type="xsd:float">5.0</y>
     </myMethod>
   </soap:body>

Schema free

There is no dict literal to create dict-inherited classes, custom dict classes with additional methods. In such case custom dict class constructor should be used, for example:

class NestedDict(dict):

    # ... skipped

state_type_map = NestedDict(**{
    'owns': 'Another',
    'uses': 'Another',
})

A div is a block element, and will span the width of the container unless a width is set. A span is an inline element, and will have the width of the text inside it. Currently, you are trying to set align as a CSS property. Align is an attribute.

<span align="center" style="border:1px solid red;">
    This is some text in a div element!
</span>

However, the align attribute is deprecated. You should use the CSS text-align property on the container.

<div style="text-align: center;">
    <span style="border:1px solid red;">
        This is some text in a div element!
    </span>
</div>

As of TypeScript 1.6, properties in object literals that do not have a corresponding property in the type they're being assigned to are flagged as errors.

Usually this error means you have a bug (typically a typo) in your code, or in the definition file. The right fix in this case would be to fix the typo. In the question, the property callbackOnLoactionHash is incorrect and should have been callbackOnLocationHash (note the mis-spelling of "Location").

This change also required some updates in definition files, so you should get the latest version of the .d.ts for any libraries you're using.

Example:

interface TextOptions {
    alignment?: string;
    color?: string;
    padding?: number;
}
function drawText(opts: TextOptions) { ... }
drawText({ align: 'center' }); // Error, no property 'align' in 'TextOptions'

But I meant to do that

There are a few cases where you may have intended to have extra properties in your object. Depending on what you're doing, there are several appropriate fixes

Type-checking only some properties

Sometimes you want to make sure a few things are present and of the correct type, but intend to have extra properties for whatever reason. Type assertions (<T>v or v as T) do not check for extra properties, so you can use them in place of a type annotation:

interface Options {
    x?: string;
    y?: number;
}

// Error, no property 'z' in 'Options'
let q1: Options = { x: 'foo', y: 32, z: 100 };
// OK
let q2 = { x: 'foo', y: 32, z: 100 } as Options;
// Still an error (good):
let q3 = { x: 100, y: 32, z: 100 } as Options;

These properties and maybe more

Some APIs take an object and dynamically iterate over its keys, but have 'special' keys that need to be of a certain type. Adding a string indexer to the type will disable extra property checking

Before

interface Model {
  name: string;
}
function createModel(x: Model) { ... }

// Error
createModel({name: 'hello', length: 100});

After

interface Model {
  name: string;
  [others: string]: any;
}
function createModel(x: Model) { ... }

// OK
createModel({name: 'hello', length: 100});

This is a dog or a cat or a horse, not sure yet

interface Animal { move; }
interface Dog extends Animal { woof; }
interface Cat extends Animal { meow; }
interface Horse extends Animal { neigh; }

let x: Animal;
if(...) {
  x = { move: 'doggy paddle', woof: 'bark' };
} else if(...) {
  x = { move: 'catwalk', meow: 'mrar' };
} else {
  x = { move: 'gallop', neigh: 'wilbur' };
}

Two good solutions come to mind here

Specify a closed set for x

// Removes all errors
let x: Dog|Cat|Horse;

or Type assert each thing

// For each initialization
  x = { move: 'doggy paddle', woof: 'bark' } as Dog;

This type is sometimes open and sometimes not

A clean solution to the "data model" problem using intersection types:

interface DataModelOptions {
  name?: string;
  id?: number;
}
interface UserProperties {
  [key: string]: any;
}
function createDataModel(model: DataModelOptions & UserProperties) {
 /* ... */
}
// findDataModel can only look up by name or id
function findDataModel(model: DataModelOptions) {
 /* ... */
}
// OK
createDataModel({name: 'my model', favoriteAnimal: 'cat' });
// Error, 'ID' is not correct (should be 'id')
findDataModel({ ID: 32 });

I'd like to add that TypeGuards only work on strings or numbers, if you want to compare an object use instanceof

if(task.id instanceof UUID) {
  //foo
}

.toString() is available, or just add "" to the end of the int

var x = 3,
    toString = x.toString(),
    toConcat = x + "";

We can do like below:

Create a new object of notification builder and call setSmallIcon() using notification builder object like in below code.

Create a method in which we will check on which OS version we are installing our app . If it is below Lolipop i.e API 21 then it will take the normal app icon with background color else it will take the transparent app icon without any background. So the devices using os version >= 21 will set the background color of icon using method setColor() of Notification builder class.

Sample Code:

NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this);

notificationBuilder.setSmallIcon(getNotificationIcon(notificationBuilder));

private int getNotificationIcon(NotificationCompat.Builder notificationBuilder) {

   if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
             int color = 0x008000;
             notificationBuilder.setColor(color);
             return R.drawable.app_icon_lolipop_above;

    } 
    return R.drawable.app_icon_lolipop_below;
}

I had the same error. I resolved in this way

Go to start- MySQL Installer-community and run again the installer as a re-configuration(you will be asked so).

Once asked if you want make MySQL instance to run as a Windows service, check the box.

In case would do not work, try unistalling and installing again, and check the box to run MySQL as Windows service.

If you have a group of radio button and you want to set radio button checked based on model, then radio button which has same value and ng-model, is checked automatically.

<input type="radio" value="1" ng-model="myRating" name="rating" class="radio">
<input type="radio" value="2" ng-model="myRating" name="rating" class="radio">
<input type="radio" value="3" ng-model="myRating" name="rating" class="radio">
<input type="radio" value="4" ng-model="myRating" name="rating" class="radio">

If the value of myRating is "2" then second radio button is selected.

I've made a short code to do that and I want to share it with you.

Here the main code:

public void Send(string from, string password, string to, string Message, string subject, string host, int port, string file)
{

  MailMessage email = new MailMessage();
  email.From = new MailAddress(from);
  email.To.Add(to);
  email.Subject = subject;
  email.Body = Message;
  SmtpClient smtp = new SmtpClient(host, port);
  smtp.UseDefaultCredentials = false;
  NetworkCredential nc = new NetworkCredential(from, password);
  smtp.Credentials = nc;
  smtp.EnableSsl = true;
  email.IsBodyHtml = true;
  email.Priority = MailPriority.Normal;
  email.BodyEncoding = Encoding.UTF8;

  if (file.Length > 0)
  {
    Attachment attachment;
    attachment = new Attachment(file);
    email.Attachments.Add(attachment);
  }

  // smtp.Send(email);
  smtp.SendCompleted += new SendCompletedEventHandler(SendCompletedCallBack);
  string userstate = "sending ...";
  smtp.SendAsync(email, userstate);
}

private static void SendCompletedCallBack(object sender,AsyncCompletedEventArgs e) {
  string result = "";
  if (e.Cancelled)
  {    
    MessageBox.Show(string.Format("{0} send canceled.", e.UserState),"Message",MessageBoxButtons.OK,MessageBoxIcon.Information);
  }
  else if (e.Error != null)
  {
    MessageBox.Show(string.Format("{0} {1}", e.UserState, e.Error), "Message", MessageBoxButtons.OK, MessageBoxIcon.Information);
  }
  else {
    MessageBox.Show("your message is sended", "Message", MessageBoxButtons.OK, MessageBoxIcon.Information);
  }

}

In your button do stuff like this
you can add your jpg or pdf files and more .. this is just an example

using (OpenFileDialog attachement = new OpenFileDialog()
{
  Filter = "Exel Client|*.png",
  ValidateNames = true
})
{
if (attachement.ShowDialog() == DialogResult.OK)
{
  Send("[email protected]", "gmail_password", 
       "[email protected]", "just smile ", "mail with attachement",
       "smtp.gmail.com", 587, attachement.FileName);

}
}

To get the behavior you want you need to wait for the process to finish before you exit Main(). To be able to tell when your process is done you need to return a Task instead of a void from your function, you should never return void from a async function unless you are working with events.

A re-written version of your program that works correctly would be

class Program {     static void Main(string[] args)     {         Debug.WriteLine("Calling DoDownload");         var downloadTask = DoDownloadAsync();         Debug.WriteLine("DoDownload done");         downloadTask.Wait(); //Waits for the background task to complete before finishing.      }      private static async Task DoDownloadAsync()     {         WebClient w = new WebClient();          string txt = await w.DownloadStringTaskAsync("http://www.google.com/");         Debug.WriteLine(txt);     } } 

Because you can not await in Main() I had to do the Wait() function instead. If this was a application that had a SynchronizationContext I would do await downloadTask; instead and make the function this was being called from async.

The most simple way would be to use the Join() method:

public static void Trail()
{
    var list = new List<string> { "lala", "lulu", "lele" };
    var data = string.Join(",", list);
}

If you really need the StringBuilder, trim the end comma after the loop:

data.ToString().TrimEnd(',');

You may use this command for listing the files for your own debuggable apk:

adb shell run-as com.corp.appName ls /data/data/com.corp.appName/cache

And this script for pulling from cache:

#!/bin/sh
adb shell "run-as com.corp.appName cat '/data/data/com.corp.appNamepp/$1' > '/sdcard/$1'"
adb pull "/sdcard/$1"
adb shell "rm '/sdcard/$1'"

Then you can pull a file from cache like this:

./pull.sh cache/someCachedData.txt

Root is not required.

As @Richard pointed out above, the onClick needs to have a capital 'C'.

$('#stop').click(function() {
     $('next').attr('onClick','stopMoving()');
}

There is Resource Tuner Console from Heaventools Software.

Let's add one more!

Recently Microsoft released a special NuGet package, System.Runtime.CompilerServices.Unsafe. It's special because it's written in IL, and provides low-level functionality not directly available in C#.

One of its methods, Unsafe.As<T>(object) allows casting any reference type to another reference type, skipping any safety checks. This is usually a very bad idea, but if both types have the same structure, it can work. So we can use this to cast a byte[] to a long[]:

bool CompareWithUnsafeLibrary(byte[] a1, byte[] a2)
{
    if (a1.Length != a2.Length) return false;

    var longSize = (int)Math.Floor(a1.Length / 8.0);
    var long1 = Unsafe.As<long[]>(a1);
    var long2 = Unsafe.As<long[]>(a2);

    for (var i = 0; i < longSize; i++)
    {
        if (long1[i] != long2[i]) return false;
    }

    for (var i = longSize * 8; i < a1.Length; i++)
    {
        if (a1[i] != a2[i]) return false;
    }

    return true;
}

Note that long1.Length would still return the original array's length, since it's stored in a field in the array's memory structure.

This method is not quite as fast as other methods demonstrated here, but it is a lot faster than the naive method, doesn't use unsafe code or P/Invoke or pinning, and the implementation is quite straightforward (IMO). Here are some BenchmarkDotNet results from my machine:

May be helpful for visual learners who want to visualise what their project state looks like after each of these commands:

For those who use Terminal with colour turned on (git config --global color.ui auto):

git reset --soft A and you will see B and C's stuff in green (staged and ready to commit)

git reset --mixed A (or git reset A) and you will see B and C's stuff in red (unstaged and ready to be staged (green) and then committed)

git reset --hard A and you will no longer see B and C's changes anywhere (will be as if they never existed)

Or for those who use a GUI program like 'Tower' or 'SourceTree'

git reset --soft A and you will see B and C's stuff in the 'staged files' area ready to commit

git reset --mixed A (or git reset A) and you will see B and C's stuff in the 'unstaged files' area ready to be moved to staged and then committed

git reset --hard A and you will no longer see B and C's changes anywhere (will be as if they never existed)

Try turning off the ReSharper Code Inspection from menu Options ? Code Inspection ? Setting and choosing Visual Studio IntelliSense (menu Option ? Intellisense ? General) instead of ReSharper IntelliSense will make it much faster.

If someone not have reference in .NET . COM (tab) or not have office installed on machine where visual was installed can do :

1. Download and install: Microsoft Office Developer Tools

2. Add references from:

   C:\Program Files (x86)\Microsoft Visual Studio 11.0\Visual Studio Tools for Office\PIA\Office15
   

You can simplify to:

WHERE a.Country = COALESCE(NULLIF(@Country,0), a.Country);

Part A: Configuring your Application Pool

Suppose the Application Pool is named 'MyPool' Go to 'Advanced Settings' of the Application Pool from the IIS Manager

1. Scroll down to 'Identity'. Trying to edit the value will bring up a dialog box. Select 'Built-In account' and under it, select 'ApplicationPoolIdentity'.

2. A few lines below 'Identity', you should find 'Load User Profile'. This value should be set to 'True'.

Part B: Configuring your website

1. Website Name: SiteName (just an example)
2. Physical Path: C:\Whatever (just an example)
3. Connect as... : Application User (pass-through authentication) (The above settings can be found in 'Basic Settings' of the site in the IIS Manager)
4. After configuring the basic settings, look for the 'Authentication' configuration under 'IIS' in the main console of the site. Open it. You should see an option for 'Anonymous Authentication'. Make sure it is enabled. Then right click and 'Edit...' it. Select 'Application Pool Identity'.

Part C: Configuring your folder

The folder in question is C:\Whatever

1. Go to Properties - Sharing - Advanced Sharing - Permissions, and tick 'Share this folder'
2. In the same dialog box, you will find a button 'Permissions'. Click it.
3. A new dialog box will open. Click 'Add'.
4. A new dialog box 'Select Users or Groups' will open. Under 'From this location' make sure the name is the same as your local host computer. Then, under 'Enter the object names', type 'IIS AppPool\MyPool' and click 'Check Names' and then 'Ok'
5. Give full sharing permissions for 'MyPool' user. Apply it and close the folder properties
6. Open folder properties again. This time, go to Security - Advanced - Permission, and click Add. There will be an option 'Select a Principal' at the top, or some other option to choose a user. Click it.
7. The 'Select Users or Groups' dialog box will open again. Repeat step 4.
8. Give all or as many permissions you need to the 'MyPool' user.
9. Check 'Replace all child object permissions..." and Apply and close.

You should now be able to use the browse the website

Windows 10 on a Network

Having your packages stored on the network drive can slow down the performance of R / R Studio considerably, and you spend a lot of time waiting for the libraries to load/install, due to the bottlenecks of having to retrieve and push data over the server back to your local host. See the following for instructions on how to create an .RProfile on your local machine:

1. Create a directory called C:\Users\xxxxxx\Documents\R\3.4 (or whatever R version you are using, and where you will store your local R packages- your directory location may be different than mine)
2. On R Console, type Sys.getenv("HOME") to get your home directory (this is where your .RProfile will be stored and R will always check there for packages- and this is on the network if packages are stored there)
3. Create a file called .Rprofile and place it in :\YOUR\HOME\DIRECTORY\ON_NETWORK (the directory you get after typing Sys.getenv("HOME") in R Console)
4. File contents of .Rprofile should be like this:

#search 2 places for packages- install new packages to first directory- load built-in packages from the second (this is from your base R package- will be different for some)

.libPaths(c("C:\Users\xxxxxx\Documents\R\3.4", "C:/Program Files/Microsoft/R Client/R_SERVER/library"))

message("*** Setting libPath to local hard drive ***")

#insert a sleep command at line 12 of the unpackPkgZip function. So, just after the package is unzipped.

trace(utils:::unpackPkgZip, quote(Sys.sleep(2)), at=12L, print=TRUE)

message("*** Add 2 second delay when installing packages, to accommodate virus scanner for R 3.4 (fixed in R 3.5+)***")

# fix problem with tcltk for sqldf package: https://github.com/ggrothendieck/sqldf#problem-involvling-tcltk

options(gsubfn.engine = "R")

message("*** Successfully loaded .Rprofile ***")

5. Restart R Studio and verify that you see that the messages above are displayed.

Now you can enjoy faster performance of your application on local host, vs. storing the packages on the network and slowing everything down.

The Javadoc generation can be skipped by setting the property maven.javadoc.skip to true [1], i.e.

-Dmaven.javadoc.skip=true

(and not false)

You can use "translateX"

<div class="box">
<div class="absolute-right"></div>
</div>

<style type="text/css">
.box{
    text-align: right;
}
.absolute-right{
    display: inline-block;
    position: absolute;
}

/*The magic:*/
.absolute-right{
-moz-transform: translateX(-100%);
-ms-transform: translateX(-100%);
-webkit-transform: translateX(-100%);
-o-transform: translateX(-100%);
transform: translateX(-100%);
}

New Selenium libraries are now out, according to: https://github.com/SeleniumHQ/selenium/issues/2110

The download page http://www.seleniumhq.org/download/ seems not to be updated just yet, but by adding 1 to the minor version in the link, I could download the C# version: http://selenium-release.storage.googleapis.com/2.53/selenium-dotnet-2.53.1.zip

It works for me with Firefox 47.0.1.

As a side note, I was able build just the webdriver.xpi Firefox extension from the master branch in GitHub, by running ./go //javascript/firefox-driver:webdriver:run – which gave an error message but did build the build/javascript/firefox-driver/webdriver.xpi file, which I could rename (to avoid a name clash) and successfully load with the FirefoxProfile.AddExtension method. That was a reasonable workaround without having to rebuild the entire Selenium library.

Use the ASCII to Integer atoi() function which accepts a string and converts it into an integer:

#include <stdlib.h>

int num = atoi("23"); // 23

If the string contains a decimal, the number will be truncated:

int num = atoi("23.21"); // 23

Complete Code Examples/Alternative Methods

I might do something like the following. Of course, with the wealth of Collection classes, i can't imagine ever needing to use this in any practical code.

public class Shift {
  public static <T> T[] left (final T... i) {
    if (1 >= i.length) {
      return i;
    }
    final T t = i[0];
    int x = 0;
    for (; x < i.length - 1; x++) {
      i[x] = i[x + 1];
    }
    i[x] = t;
    return i;
  }
}

Called with two arguments, it's a swap.

It can be used as follows:

int x = 1;
int y = 2;
Integer[] yx = Shift.left(x,y);

Alternatively:

Integer[] yx = {x,y};
Shift.left(yx);

Then

x = yx[0];
y = yx[1];

Note: it auto-boxes primitives.

In Gecko, Safari, Opera, ‘visible’ becomes ‘auto’ also when combined with ‘hidden’ (in other words: ‘visible’ becomes ‘auto’ when combined with anything else different from ‘visible’). Gecko 1.8, Safari 3, Opera 9.5 are pretty consistent among them.

also the W3C spec says:

The computed values of ‘overflow-x’ and ‘overflow-y’ are the same as their specified values, except that some combinations with ‘visible’ are not possible: if one is specified as ‘visible’ and the other is ‘scroll’ or ‘auto’, then ‘visible’ is set to ‘auto’. The computed value of ‘overflow’ is equal to the computed value of ‘overflow-x’ if ‘overflow-y’ is the same; otherwise it is the pair of computed values of ‘overflow-x’ and ‘overflow-y’.

Short Version:

If you are using visible for either overflow-x or overflow-y and something other than visible for the other, the visible value is interpreted as auto.

Polymorphism is when you can treat an object as a generic version of something, but when you access it, the code determines which exact type it is and calls the associated code.

Here is an example in C#. Create four classes within a console application:

public abstract class Vehicle
{
    public abstract int Wheels;
}

public class Bicycle : Vehicle
{
    public override int Wheels()
    {
        return 2;
    }
}

public class Car : Vehicle
{
    public override int Wheels()
    {
        return 4;
    }
}

public class Truck : Vehicle
{
    public override int Wheels()
    {
        return 18;
    }
}

Now create the following in the Main() of the module for the console application:

public void Main()
{
    List<Vehicle> vehicles = new List<Vehicle>();

    vehicles.Add(new Bicycle());
    vehicles.Add(new Car());
    vehicles.Add(new Truck());

    foreach (Vehicle v in vehicles)
    {
        Console.WriteLine(
            string.Format("A {0} has {1} wheels.",
                v.GetType().Name, v.Wheels));
    }
}

In this example, we create a list of the base class Vehicle, which does not know about how many wheels each of its sub-classes has, but does know that each sub-class is responsible for knowing how many wheels it has.

We then add a Bicycle, Car and Truck to the list.

Next, we can loop through each Vehicle in the list, and treat them all identically, however when we access each Vehicles 'Wheels' property, the Vehicle class delegates the execution of that code to the relevant sub-class.

This code is said to be polymorphic, as the exact code which is executed is determined by the sub-class being referenced at runtime.

I hope that this helps you.

Just in case anybody want to find how in oracle and came here (like me), the syntax is

select length(FIELD) from TABLE

just in case ;)

This needs bash 4.1 if you use {fd} or local -n.

The rest should work in bash 3.x I hope. I am not completely sure due to printf %q - this might be a bash 4 feature.

Summary

Your example can be modified as follows to archive the desired effect:

# Add following 4 lines:
_passback() { while [ 1 -lt $# ]; do printf '%q=%q;' "$1" "${!1}"; shift; done; return $1; }
passback() { _passback "$@" "$?"; }
_capture() { { out="$("${@:2}" 3<&-; "$2_" >&3)"; ret=$?; printf "%q=%q;" "$1" "$out"; } 3>&1; echo "(exit $ret)"; }
capture() { eval "$(_capture "$@")"; }

e=2

# Add following line, called "Annotation"
function test1_() { passback e; }
function test1() {
  e=4
  echo "hello"
}

# Change following line to:
capture ret test1 

echo "$ret"
echo "$e"

prints as desired:

hello
4

Note that this solution:

• Works for e=1000, too.
• Preserves $? if you need $?

The only bad sideffects are:

• It needs a modern bash.
• It forks quite more often.
• It needs the annotation (named after your function, with an added _)
• It sacrifices file descriptor 3.
  • You can change it to another FD if you need that.
    • In _capture just replace all occurances of 3 with another (higher) number.

The following (which is quite long, sorry for that) hopefully explains, how to adpot this recipe to other scripts, too.

The problem

d() { let x++; date +%Y%m%d-%H%M%S; }

x=0
d1=$(d)
d2=$(d)
d3=$(d)
d4=$(d)
echo $x $d1 $d2 $d3 $d4

outputs

0 20171129-123521 20171129-123521 20171129-123521 20171129-123521

while the wanted output is

4 20171129-123521 20171129-123521 20171129-123521 20171129-123521

The cause of the problem

Shell variables (or generally speaking, the environment) is passed from parental processes to child processes, but not vice versa.

If you do output capturing, this usually is run in a subshell, so passing back variables is difficult.

Some even tell you, that it is impossible to fix. This is wrong, but it is a long known difficult to solve problem.

There are several ways on how to solve it best, this depends on your needs.

Here is a step by step guide on how to do it.

Passing back variables into the parental shell

There is a way to pass back variables to a parental shell. However this is a dangerous path, because this uses eval. If done improperly, you risk many evil things. But if done properly, this is perfectly safe, provided that there is no bug in bash.

_passback() { while [ 0 -lt $# ]; do printf '%q=%q;' "$1" "${!1}"; shift; done; }

d() { let x++; d=$(date +%Y%m%d-%H%M%S); _passback x d; }

x=0
eval `d`
d1=$d
eval `d`
d2=$d
eval `d`
d3=$d
eval `d`
d4=$d
echo $x $d1 $d2 $d3 $d4

prints

4 20171129-124945 20171129-124945 20171129-124945 20171129-124945

Note that this works for dangerous things, too:

danger() { danger="$*"; passback danger; }
eval `danger '; /bin/echo *'`
echo "$danger"

prints

; /bin/echo *

This is due to printf '%q', which quotes everything such, that you can re-use it in a shell context safely.

But this is a pain in the a..

This does not only look ugly, it also is much to type, so it is error prone. Just one single mistake and you are doomed, right?

Well, we are at shell level, so you can improve it. Just think about an interface you want to see, and then you can implement it.

Augment, how the shell processes things

Let's go a step back and think about some API which allows us to easily express, what we want to do.

Well, what do we want do do with the d() function?

We want to capture the output into a variable. OK, then let's implement an API for exactly this:

# This needs a modern bash 4.3 (see "help declare" if "-n" is present,
# we get rid of it below anyway).
: capture VARIABLE command args..
capture()
{
local -n output="$1"
shift
output="$("$@")"
}

Now, instead of writing

d1=$(d)

we can write

capture d1 d

Well, this looks like we haven't changed much, as, again, the variables are not passed back from d into the parent shell, and we need to type a bit more.

However now we can throw the full power of the shell at it, as it is nicely wrapped in a function.

Think about an easy to reuse interface

A second thing is, that we want to be DRY (Don't Repeat Yourself). So we definitively do not want to type something like

x=0
capture1 x d1 d
capture1 x d2 d
capture1 x d3 d
capture1 x d4 d
echo $x $d1 $d2 $d3 $d4

The x here is not only redundant, it's error prone to always repeate in the correct context. What if you use it 1000 times in a script and then add a variable? You definitively do not want to alter all the 1000 locations where a call to d is involved.

So leave the x away, so we can write:

_passback() { while [ 0 -lt $# ]; do printf '%q=%q;' "$1" "${!1}"; shift; done; }

d() { let x++; output=$(date +%Y%m%d-%H%M%S); _passback output x; }

xcapture() { local -n output="$1"; eval "$("${@:2}")"; }

x=0
xcapture d1 d
xcapture d2 d
xcapture d3 d
xcapture d4 d
echo $x $d1 $d2 $d3 $d4

outputs

4 20171129-132414 20171129-132414 20171129-132414 20171129-132414

This already looks very good. (But there still is the local -n which does not work in oder common bash 3.x)

Avoid changing d()

The last solution has some big flaws:

• d() needs to be altered
• It needs to use some internal details of xcapture to pass the output.
  • Note that this shadows (burns) one variable named output, so we can never pass this one back.
• It needs to cooperate with _passback

Can we get rid of this, too?

Of course, we can! We are in a shell, so there is everything we need to get this done.

If you look a bit closer to the call to eval you can see, that we have 100% control at this location. "Inside" the eval we are in a subshell, so we can do everything we want without fear of doing something bad to the parental shell.

Yeah, nice, so let's add another wrapper, now directly inside the eval:

_passback() { while [ 0 -lt $# ]; do printf '%q=%q;' "$1" "${!1}"; shift; done; }
# !DO NOT USE!
_xcapture() { "${@:2}" > >(printf "%q=%q;" "$1" "$(cat)"); _passback x; }  # !DO NOT USE!
# !DO NOT USE!
xcapture() { eval "$(_xcapture "$@")"; }

d() { let x++; date +%Y%m%d-%H%M%S; }

x=0
xcapture d1 d
xcapture d2 d
xcapture d3 d
xcapture d4 d
echo $x $d1 $d2 $d3 $d4

prints

4 20171129-132414 20171129-132414 20171129-132414 20171129-132414                                                    

However, this, again, has some major drawback:

• The !DO NOT USE! markers are there, because there is a very bad race condition in this, which you cannot see easily:
  • The >(printf ..) is a background job. So it might still execute while the _passback x is running.
  • You can see this yourself if you add a sleep 1; before printf or _passback. _xcapture a d; echo then outputs x or a first, respectively.
• The _passback x should not be part of _xcapture, because this makes it difficult to reuse that recipe.
• Also we have some unneded fork here (the $(cat)), but as this solution is !DO NOT USE! I took the shortest route.

However, this shows, that we can do it, without modification to d() (and without local -n)!

Please note that we not neccessarily need _xcapture at all, as we could have written everyting right in the eval.

However doing this usually isn't very readable. And if you come back to your script in a few years, you probably want to be able to read it again without much trouble.

Fix the race

Now let's fix the race condition.

The trick could be to wait until printf has closed it's STDOUT, and then output x.

There are many ways to archive this:

• You cannot use shell pipes, because pipes run in different processes.
• One can use temporary files,
• or something like a lock file or a fifo. This allows to wait for the lock or fifo,
• or different channels, to output the information, and then assemble the output in some correct sequence.

Following the last path could look like (note that it does the printf last because this works better here):

_passback() { while [ 0 -lt $# ]; do printf '%q=%q;' "$1" "${!1}"; shift; done; }

_xcapture() { { printf "%q=%q;" "$1" "$("${@:2}" 3<&-; _passback x >&3)"; } 3>&1; }

xcapture() { eval "$(_xcapture "$@")"; }

d() { let x++; date +%Y%m%d-%H%M%S; }

x=0
xcapture d1 d
xcapture d2 d
xcapture d3 d
xcapture d4 d
echo $x $d1 $d2 $d3 $d4

outputs

4 20171129-144845 20171129-144845 20171129-144845 20171129-144845

Why is this correct?

• _passback x directly talks to STDOUT.
• However, as STDOUT needs to be captured in the inner command, we first "save" it into FD3 (you can use others, of course) with '3>&1' and then reuse it with >&3.
• The $("${@:2}" 3<&-; _passback x >&3) finishes after the _passback, when the subshell closes STDOUT.
• So the printf cannot happen before the _passback, regardless how long _passback takes.
• Note that the printf command is not executed before the complete commandline is assembled, so we cannot see artefacts from printf, independently how printf is implemented.

Hence first _passback executes, then the printf.

This resolves the race, sacrificing one fixed file descriptor 3. You can, of course, choose another file descriptor in the case, that FD3 is not free in your shellscript.

Please also note the 3<&- which protects FD3 to be passed to the function.

Make it more generic

_capture contains parts, which belong to d(), which is bad, from a reusability perspective. How to solve this?

Well, do it the desparate way by introducing one more thing, an additional function, which must return the right things, which is named after the original function with _ attached.

This function is called after the real function, and can augment things. This way, this can be read as some annotation, so it is very readable:

_passback() { while [ 0 -lt $# ]; do printf '%q=%q;' "$1" "${!1}"; shift; done; }
_capture() { { printf "%q=%q;" "$1" "$("${@:2}" 3<&-; "$2_" >&3)"; } 3>&1; }
capture() { eval "$(_capture "$@")"; }

d_() { _passback x; }
d() { let x++; date +%Y%m%d-%H%M%S; }

x=0
capture d1 d
capture d2 d
capture d3 d
capture d4 d
echo $x $d1 $d2 $d3 $d4

still prints

4 20171129-151954 20171129-151954 20171129-151954 20171129-151954

Allow access to the return-code

There is only on bit missing:

v=$(fn) sets $? to what fn returned. So you probably want this, too. It needs some bigger tweaking, though:

# This is all the interface you need.
# Remember, that this burns FD=3!
_passback() { while [ 1 -lt $# ]; do printf '%q=%q;' "$1" "${!1}"; shift; done; return $1; }
passback() { _passback "$@" "$?"; }
_capture() { { out="$("${@:2}" 3<&-; "$2_" >&3)"; ret=$?; printf "%q=%q;" "$1" "$out"; } 3>&1; echo "(exit $ret)"; }
capture() { eval "$(_capture "$@")"; }

# Here is your function, annotated with which sideffects it has.
fails_() { passback x y; }
fails() { x=$1; y=69; echo FAIL; return 23; }

# And now the code which uses it all
x=0
y=0
capture wtf fails 42
echo $? $x $y $wtf

prints

23 42 69 FAIL

There is still a lot room for improvement

• _passback() can be elmininated with passback() { set -- "$@" "$?"; while [ 1 -lt $# ]; do printf '%q=%q;' "$1" "${!1}"; shift; done; return $1; }

• _capture() can be eliminated with capture() { eval "$({ out="$("${@:2}" 3<&-; "$2_" >&3)"; ret=$?; printf "%q=%q;" "$1" "$out"; } 3>&1; echo "(exit $ret)")"; }

• The solution pollutes a file descriptor (here 3) by using it internally. You need to keep that in mind if you happen to pass FDs.
  Note thatbash 4.1 and above has {fd} to use some unused FD.
  (Perhaps I will add a solution here when I come around.)
  Note that this is why I use to put it in separate functions like _capture, because stuffing this all into one line is possible, but makes it increasingly harder to read and understand

• Perhaps you want to capture STDERR of the called function, too. Or you want to even pass in and out more than one filedescriptor from and to variables.
  I have no solution yet, however here is a way to catch more than one FD, so we can probably pass back the variables this way, too.

Also do not forget:

This must call a shell function, not an external command.

There is no easy way to pass environment variables out of external commands. (With LD_PRELOAD= it should be possible, though!) But this then is something completely different.

Last words

This is not the only possible solution. It is one example to a solution.

As always you have many ways to express things in the shell. So feel free to improve and find something better.

The solution presented here is quite far from being perfect:

• It was nearly not testet at all, so please forgive typos.
• There is a lot of room for improvement, see above.
• It uses many features from modern bash, so probably is hard to port to other shells.
• And there might be some quirks I haven't thought about.

However I think it is quite easy to use:

• Add just 4 lines of "library".
• Add just 1 line of "annotation" for your shell function.
• Sacrifices just one file descriptor temporarily.
• And each step should be easy to understand even years later.

Since dates are converted to UNIX epoch (numbers), you can use Math.max/min to find those:

var maxDate = Math.max.apply(null, dates)
// convert back to date object
maxDate = new Date(maxDate)

(tested in chrome only, but should work in most browsers)

The same way you make anything else negative: put a negative sign in front of it.

var positive = 6;
var negative = -positive;

From here:

The function ord() gets the int value of the char. And in case you want to convert back after playing with the number, function chr() does the trick.

>>> ord('a')
97
>>> chr(97)
'a'
>>> chr(ord('a') + 3)
'd'
>>>

In Python 2, there was also the unichr function, returning the Unicode character whose ordinal is the unichr argument:

>>> unichr(97)
u'a'
>>> unichr(1234)
u'\u04d2'

In Python 3 you can use chr instead of unichr.

ord() - Python 3.6.5rc1 documentation

ord() - Python 2.7.14 documentation

If the problem allows it, try with EXISTS, since it's optimized to end as soon as a result is found (And don't buffer any response), so, if you are just trying to normalize data for a WHERE clause like this

SELECT FROM SOMETHING S WHERE S.ID IN ( SELECT DISTINCT DCR.SOMETHING_ID FROM DIFF_CARDINALITY_RELATIONSHIP DCR ) -- to keep same cardinality

A faster response would be:

SELECT FROM SOMETHING S WHERE EXISTS ( SELECT 1 FROM DIFF_CARDINALITY_RELATIONSHIP DCR WHERE DCR.SOMETHING_ID = S.ID )

This isn't always possible but when available you will see a faster response.

Now you can add/use instances with in the method

public class Myprogram7 {

  Scanner scan;
  int compareCount = 0;
  int low = 0;
  int high = 0;
  int mid = 0;  
  int key = 0;  
  Scanner temp;  
  int[]list;  
  String menu, outputString;  
  int option = 1;  
  boolean found = false;  

  private void readLine() {

  }

  private void findkey() {

  }

  private void printCount() {

  }
  public static void main(String[] args){

    Myprogram7 myprg=new Myprogram7();
    myprg.readLine();
    myprg.findkey();
    myprg.printCount();
  }
}

1. Add using

using System.ComponentModel;

2. Declare Background Worker:

private readonly BackgroundWorker worker = new BackgroundWorker();

3. Subscribe to events:

worker.DoWork += worker_DoWork;
worker.RunWorkerCompleted += worker_RunWorkerCompleted;

4. Implement two methods:

private void worker_DoWork(object sender, DoWorkEventArgs e)
{
  // run all background tasks here
}

private void worker_RunWorkerCompleted(object sender, 
                                           RunWorkerCompletedEventArgs e)
{
  //update ui once worker complete his work
}

5. Run worker async whenever your need.

worker.RunWorkerAsync();

6. Track progress (optional, but often useful)

   a) subscribe to ProgressChanged event and use ReportProgress(Int32) in DoWork

   b) set worker.WorkerReportsProgress = true; (credits to @zagy)

If you want to resize an image after it is loaded, you can attach to the onload event of the <img> tag. Note that it may not be supported in all browsers (Microsoft's reference claims it is part of the HTML 4.0 spec, but the HTML 4.0 spec doesn't list the onload event for <img>).

The code below is tested and working in: IE 6, 7 & 8, Firefox 2, 3 & 3.5, Opera 9 & 10, Safari 3 & 4 and Google Chrome:

<img src="yourImage.jpg" border="0" height="real_height" width="real_width"
    onload="resizeImg(this, 200, 100);">

<script type="text/javascript">
function resizeImg(img, height, width) {
    img.height = height;
    img.width = width;
}
</script>

Try using Relative (a Windows command-line application).

Basically, a shortcut could have a relative link, but Windows gives no way to actually make one.

To disable all previous dates, give start date as today date

startDate: new Date()

Solution: disable all previous dates from today

$(function() {_x000D_
    $( "#datepicker" ).datepicker({ startDate: new Date()});_x000D_
 });

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
<link href="https://cdnjs.cloudflare.com/ajax/libs/datepicker/0.6.5/datepicker.min.css" rel="stylesheet"/>_x000D_
<script src="https://cdnjs.cloudflare.com/ajax/libs/datepicker/0.6.5/datepicker.min.js"></script>_x000D_
_x000D_
<div> Select Date <input type="text" id="datepicker" /></div>

Solution: disable all past dates from a particular date.

$(function() {_x000D_
    $( "#datepicker" ).datepicker({ startDate: new Date("2019-10-15")});_x000D_
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
<link href="https://cdnjs.cloudflare.com/ajax/libs/datepicker/0.6.5/datepicker.min.css" rel="stylesheet"/>_x000D_
<script src="https://cdnjs.cloudflare.com/ajax/libs/datepicker/0.6.5/datepicker.min.js"></script>_x000D_
_x000D_
<div> Select Date <input type="text" id="datepicker" /></div>

This will disable all days before the date 15th October 2019 (2019-10-15)

This is how I have dealt with it in the past:

$().ready(function() {                                                      
    $("#contact").validate({
        submitHandler: function(form) {
            // see if selectone is even being used
            var boxes = $('.selectone:checkbox');
            if(boxes.length > 0) {
                if( $('.selectone:checkbox:checked').length < 1) {
                    alert('Please select at least one checkbox');
                    boxes[0].focus();
                    return false;
                }
            }
            form.submit();
        }
    }); 

});

if your php version is Non-Thread-Safe (nts) you must use php extension with format example: extension=php_cl_dbg_5_2_nts.dll else if your php version is Thread-Safe (ts) you must use php extension with format example: extension=php_cl_dbg_5_2_ts.dll (notice bolded words)

So if get error like above. Firstly, check your PHP version is nts or ts, if is nts.
Then check in php.ini whether has any line like zend_extension_ts="C:\xammp\php\ext\php_dbg.dll-5.2.x" choose right version of php_dbg.dll-5.2.x from it homepage (google for it). Change from zend_extension_ts to zend_extension_nts.

Hope this help.

An Object if passed as a value type then changes made to the members of the object inside the method are impacted outside the method also. But if the object itself is set to another object or reinitialized then it will not be reflected outside the method. So i would say object as a whole is passed as Valuetype only but object members are still reference type.

        private void button1_Click(object sender, EventArgs e)
    {
        Class1 objc ;
         objc = new Class1();
        objc.empName = "name1";
        checkobj( objc);
        MessageBox.Show(objc.empName);  //propert value changed; but object itself did not change
    }
    private void checkobj ( Class1 objc)
    {
        objc.empName = "name 2";
        Class1 objD = new Class1();
        objD.empName ="name 3";
        objc = objD ;
        MessageBox.Show(objc.empName);  //name 3
    }

Demo :

<connectionStrings>
<add name="myConnectionString" connectionString="server=localhost;database=myDb;uid=myUser;password=myPass;" />
</connectionStrings>

Based on your question:

<connectionStrings>
    <add name="itmall" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=D:\19-02\ABCC\App_Data\abcc.mdf;Integrated Security=True;User Instance=True" />
    </connectionStrings>

Refer links:

http://www.connectionstrings.com/store-connection-string-in-webconfig/

Retrive connection string from web.config file:

write the below code in your file where you want;

string connstring=ConfigurationManager.ConnectionStrings["itmall"].ConnectionString;

SqlConnection con = new SqlConnection(connstring);

or you can go in your way like

SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["itmall"].ConnectionString);

Note:

The "name" which you gave in web.config file and name which you used in connection string must be same(like "itmall" in this solution.)

Using non-lambda, query-syntax LINQ, you can do this:

var movies = from row in _db.Movies 
             orderby row.Category, row.Name
             select row;

[EDIT to address comment] To control the sort order, use the keywords ascending (which is the default and therefore not particularly useful) or descending, like so:

var movies = from row in _db.Movies 
             orderby row.Category descending, row.Name
             select row;

try this way Simply loop through that, building your own array. This code assumes it's an array of strings, it shouldn't be hard to modify to suit your particular array structure.

JSONArray jsonArray = new JSONArray(jsonArrayString);
List<String> list = new ArrayList<String>();
for (int i=0; i<jsonArray.length(); i++) {
    list.add( jsonArray.getString(i) );

you can use PHP's end()

$array = array('a' => 1,'b' => 2,'c' => 3);
$lastElement = end($array);
foreach($array as $k => $v) {
    echo $v . '<br/>';
    if($v == $lastElement) {
         // 'you can do something here as this condition states it just entered last element of an array'; 
    }
}

Update1

as pointed out by @Mijoja the above could will have problem if you have same value multiple times in array. below is the fix for it.

$array = array('a' => 1, 'b' => 2, 'c' => 3, 'd' => 2);
//point to end of the array
end($array);
//fetch key of the last element of the array.
$lastElementKey = key($array);
//iterate the array
foreach($array as $k => $v) {
    if($k == $lastElementKey) {
        //during array iteration this condition states the last element.
    }
}

Update2

I found solution by @onteria_ to be better then what i have answered since it does not modify arrays internal pointer, i am updating the answer to match his answer.

$array = array('a' => 1, 'b' => 2, 'c' => 3, 'd' => 2);
// Get array keys
$arrayKeys = array_keys($array);
// Fetch last array key
$lastArrayKey = array_pop($arrayKeys);
//iterate array
foreach($array as $k => $v) {
    if($k == $lastArrayKey) {
        //during array iteration this condition states the last element.
    }
}

Thank you @onteria_

Update3

As pointed by @CGundlach PHP 7.3 introduced array_key_last which seems much better option if you are using PHP >= 7.3

$array = array('a' => 1,'b' => 2,'c' => 3);
$lastKey = array_key_last($array);
foreach($array as $k => $v) {
    echo $v . '<br/>';
    if($k == $lastKey) {
         // 'you can do something here as this condition states it just entered last element of an array'; 
    }
}

Another option would be to use the package ggplot2.

ggplot(mydata, aes(x = V3)) + geom_histogram() + scale_x_log10()

Try setting delays:

[_tableView performSelector:@selector(reloadData) withObject:nil afterDelay:0.2];
[_activityIndicator performSelector:@selector(stopAnimating) withObject:nil afterDelay:0.2];

This worked for me.

i faced the same problem but i solved it by moving the chromedriver to this path '/opt/google/chrome/'

I was able to resolve this problem by cleaning my assets cache:

If you want to change the default container and you are using Virtualbox, you can do it via the commandline / CLI:

docker-machine stop
VBoxManage modifyvm default --cpus 2
VBoxManage modifyvm default --memory 4096
docker-machine start

You can use strcmp:

break x:20 if strcmp(y, "hello") == 0

20 is line number, x can be any filename and y can be any variable.

As far as I know, a forced update like this is not directly possible. You might be able to reduce the DNS downtime by reducing the TTL (Time-To-Live) value of the entries before changing them, if your name server service provider allows that.

Here's a guide for less painful DNS changes.

A fair warning, though - not all name servers between your client and the authoritative (origin) name server will enforce your TTL, they might have their own caching time.

It's supposed to be as simple as this:

<select id='multipleSelect' multiple='multiple'>
  <option value="1">1</option>
  <option value="2">2</option>
  <option value="3">3</option>
</select>
<script type='text/javascript'>
    $('#multipleSelect').val(['1', '2']);
</script>

The following works fine for me in Excel 2007. It is simple, and performs a full copy (retains all formatting, etc.):

Sheets("Sheet1").Columns(1).Copy Destination:=Sheets("Sheet2").Columns(2)

"Columns" returns a Range object, and so this is utilizing the "Range.Copy" method. "Destination" is an option to this method - if not provided the default is to copy to the paste buffer. But when provided, it is an easy way to copy.

As when manually copying items in Excel, the size and geometry of the destination must support the range being copied.

You are using Lists, concrete ArrayList. ArrayList also implements Collection interface. Collection interface has sort method which is used to sort the elements present in the specified list of Collection in ascending order. This will be the quickest and possibly the best way for your case.

Sorting a list in ascending order can be performed as default operation on this way:

Collections.sort(list);

Sorting a list in descending order can be performed on this way:

Collections.reverse(list);

According to these facts, your solution has to be written like this:

public class tes 
{
    public static void main(String args[])
    {
        List<Integer> lList = new ArrayList<Integer>();
        lList.add(4);
        lList.add(1);
        lList.add(7);
        lList.add(2);
        lList.add(9);
        lList.add(1);
        lList.add(5);

        Collections.sort(lList);
        for(int i=0; i<lList.size();i++ )
        {
            System.out.println(lList.get(i));
        }
     }
}

Flexible Box Layout Module - 8.1. Aligning with auto margins

Auto margins on flex items have an effect very similar to auto margins in block flow:

• During calculations of flex bases and flexible lengths, auto margins are treated as 0.

• Prior to alignment via justify-content and align-self, any positive free space is distributed to auto margins in that dimension.

Therefore you could use margin-top: auto to distribute the space between the other elements and the last element.

This will position the last element at the bottom.

p:last-of-type {
  margin-top: auto;
}

.container {
  display: flex;
  flex-direction: column;
  border: 1px solid #000;
  min-height: 200px;
  width: 100px;
}
p {
  height: 30px;
  background-color: blue;
  margin: 5px;
}
p:last-of-type {
  margin-top: auto;
}

<div class="container">
  <p></p>
  <p></p>
  <p></p>
</div>

Likewise, you can also use margin-left: auto or margin-right: auto for the same alignment horizontally.

p:last-of-type {
  margin-left: auto;
}

.container {
  display: flex;
  width: 100%;
  border: 1px solid #000;
}
p {
  height: 50px;
  width: 50px;
  background-color: blue;
  margin: 5px;
}
p:last-of-type {
  margin-left: auto;
}

<div class="container">
  <p></p>
  <p></p>
  <p></p>
  <p></p>
</div>

This page writes well about the protected & default access modifier

.... Protected: Protected access modifier is the a little tricky and you can say is a superset of the default access modifier. Protected members are same as the default members as far as the access in the same package is concerned. The difference is that, the protected members are also accessible to the subclasses of the class in which the member is declared which are outside the package in which the parent class is present.

But these protected members are “accessible outside the package only through inheritance“. i.e you can access a protected member of a class in its subclass present in some other package directly as if the member is present in the subclass itself. But that protected member will not be accessible in the subclass outside the package by using parent class’s reference. ....

Whether ads are shown on a video is up to the content owner of that video. It's not something that the embedder can control.

If you had permission from the content owners of the videos to upload copies in your own account, and then ensured that your account was set up with monetization turned off, then that would prevent ads from showing during playback. It's up to you to work out that arrangement/permission with the original videos' owners, of course.

(It's also worth pointing out that if your goal is to help non-profits raise money, then allowing them to monetize their video playbacks is in line with that goal...)

This works perfectly, from ECMA

document.addEventListener("DOMContentLoaded", function() {
  // code...
});

The window.onload doesn't equal to JQuery $(document).ready because $(document).ready waits only to the DOM tree while window.onload check all elements including external assets and images.

EDIT: Added IE8 and older equivalent, thanks to Jan Derk's observation. You may read the source of this code on MDN at this link:

// alternative to DOMContentLoaded
document.onreadystatechange = function () {
    if (document.readyState == "interactive") {
        // Initialize your application or run some code.
    }
}

There are other options apart from "interactive". See the MDN link for details.

The context parameter just sets the value of this in the iterator function.

var someOtherArray = ["name","patrick","d","w"];

_.each([1, 2, 3], function(num) { 
    // In here, "this" refers to the same Array as "someOtherArray"

    alert( this[num] ); // num is the value from the array being iterated
                        //    so this[num] gets the item at the "num" index of
                        //    someOtherArray.
}, someOtherArray);

Working Example: http://jsfiddle.net/a6Rx4/

It uses the number from each member of the Array being iterated to get the item at that index of someOtherArray, which is represented by this since we passed it as the context parameter.

If you do not set the context, then this will refer to the window object.

Local AJAX calls in Chrome are not supported due to same-origin-policy.

Error message on chrome is like this: "Cross origin requests are not supported for protocol schemes: http, data, chrome, chrome-extension, https."

This means that chrome creates a virtual disk for every domain to keep the files served by the domain using http/https protocols. Any access to files outside this virtual disk are restricted under same origin policy. AJAX requests and responses happen on http/https, therefore wont work for local files.

Firefox does not put such restriction, therefore your code will work happily on the Firefox. However there are workarounds for chrome too : see here.

Matplolib now allows for 'annotation lines' as the OP was seeking. The annotate() function allows several forms of connecting paths and a headless and tailess arrow, i.e., a simple line, is one of them.

ax.annotate("",
            xy=(0.2, 0.2), xycoords='data',
            xytext=(0.8, 0.8), textcoords='data',
            arrowprops=dict(arrowstyle="-",
                      connectionstyle="arc3, rad=0"),
            )

In the documentation it says you can draw only an arrow with an empty string as the first argument.

From the OP's example:

%matplotlib notebook
import numpy as np
import matplotlib.pyplot as plt

np.random.seed(5)
x = np.arange(1, 101)
y = 20 + 3 * x + np.random.normal(0, 60, 100)
plt.plot(x, y, "o")


# draw vertical line from (70,100) to (70, 250)
plt.annotate("",
              xy=(70, 100), xycoords='data',
              xytext=(70, 250), textcoords='data',
              arrowprops=dict(arrowstyle="-",
                              connectionstyle="arc3,rad=0."), 
              )

# draw diagonal line from (70, 90) to (90, 200)
plt.annotate("",
              xy=(70, 90), xycoords='data',
              xytext=(90, 200), textcoords='data',
              arrowprops=dict(arrowstyle="-",
                              connectionstyle="arc3,rad=0."), 
              )

plt.show()

Just as in the approach in gcalmettes's answer, you can choose the color, line width, line style, etc..

Here is an alteration to a portion of the code that would make one of the two example lines red, wider, and not 100% opaque.

# draw vertical line from (70,100) to (70, 250)
plt.annotate("",
              xy=(70, 100), xycoords='data',
              xytext=(70, 250), textcoords='data',
              arrowprops=dict(arrowstyle="-",
                              edgecolor = "red",
                              linewidth=5,
                              alpha=0.65,
                              connectionstyle="arc3,rad=0."), 
              )

You can also add curve to the connecting line by adjusting the connectionstyle.

I think you will have to loop over the "inserted" table, which contains all rows that were updated. You can use a WHERE loop, or a WITH statement if your primary key is a GUID. This is the simpler (for me) to write, so here is my example. We use this approach, so I know for a fact it works fine.

ALTER TRIGGER [dbo].[RA2Newsletter] ON [dbo].[Reiseagent]
    AFTER INSERT
AS
        -- This is your primary key.  I assume INT, but initialize
        -- to minimum value for the type you are using.
        DECLARE @rAgent_ID INT = 0

        -- Looping variable.
        DECLARE @i INT = 0

        -- Count of rows affected for looping over
        DECLARE @count INT

        -- These are your old variables.
        DECLARE @rAgent_Name NVARCHAR(50)
        DECLARE @rAgent_Email NVARCHAR(50)
        DECLARE @rAgent_IP NVARCHAR(50)
        DECLARE @hotelID INT
        DECLARE @retval INT

    BEGIN 
        SET NOCOUNT ON ;

        -- Get count of affected rows
        SELECT  @Count = Count(rAgent_ID)
        FROM    inserted

        -- Loop over rows affected
        WHILE @i < @count
            BEGIN
                -- Get the next rAgent_ID
                SELECT TOP 1
                        @rAgent_ID = rAgent_ID
                FROM    inserted
                WHERE   rAgent_ID > @rAgent_ID
                ORDER BY rAgent_ID ASC

                -- Populate values for the current row
                SELECT  @rAgent_Name = rAgent_Name,
                        @rAgent_Email = rAgent_Email,
                        @rAgent_IP = rAgent_IP,
                        @hotelID = hotelID
                FROM    Inserted
                WHERE   rAgent_ID = @rAgent_ID

                -- Run your stored procedure
                EXEC insert2Newsletter '', '', @rAgent_Name, @rAgent_Email,
                    @rAgent_IP, @hotelID, 'RA', @retval 

                -- Set up next iteration
                SET @i = @i + 1
            END
    END 
GO

I sure hope this helps you out. Cheers!

You can use pragma related commands in sqlite like below

pragma table_info("table_name")
--Alternatively
select * from pragma_table_info("table_name")

If you require column names like id|foo|bar|age|street|address, basically your answer is in below query.

select group_concat(name,'|') from pragma_table_info("table_name")

Maybe the most intuitive solution is probably to use the stringr function str_remove which is even easier than str_replace as it has only 1 argument instead of 2.

The only tricky part in your example is that you want to keep the underscore but its possible: You must match the regular expression until it finds the specified string pattern (?=pattern).

See example:

strings = c("TGAS_1121", "MGAS_1432", "ATGAS_1121")
strings %>% stringr::str_remove(".+?(?=_)")

[1] "_1121" "_1432" "_1121"

In my case, this error happened with a new project.

none of the proposed solutions here worked, so I simply reinstalled all the packages and started working correctly.

I think that most fast way should not taking higher than O(n^2) also in this way you can use just O(1) space :
the way to do that is to swap in pairs because when you transpose a matrix then what you do is: M[i][j]=M[j][i] , so store M[i][j] in temp, then M[i][j]=M[j][i],and the last step : M[j][i]=temp. this could be done by one pass so it should take O(n^2)

In python \ (backslash) is used as an escape character. What this means that in places where you wish to insert a special character (such as newline), you would use the backslash and another character (\n for newline)

With your example string you would notice that when you put "C:\Users\Josh\Desktop\20130216" in the repl you will get "C:\\Users\\Josh\\Desktop\x8130216". This is because \2 has a special meaning in a python string. If you wish to specify \ then you need to put two \\ in your string.

"C:\\Users\\Josh\\Desktop\\28130216"

The other option is to notify python that your entire string must NOT use \ as an escape character by pre-pending the string with r

r"C:\Users\Josh\Desktop\20130216"

This is a "raw" string, and very useful in situations where you need to use lots of backslashes such as with regular expression strings.

In case you still wish to replace that single \ with \\ you would then use:

directory = string.replace(r"C:\Users\Josh\Desktop\20130216", "\\", "\\\\")

Notice that I am not using r' in the last two strings above. This is because, when you use the r' form of strings you cannot end that string with a single \

Why can't Python's raw string literals end with a single backslash?

On Python 3.4, the pathlib module was added, and the following code will reliably open a file in the same directory as the current script:

from pathlib import Path

p = Path(__file__).with_name('file.txt')
with p.open('r') as f:
    print(f.read())

You can also use parent.absolute() to get directory value as a string if needed:

p = Path(__file__)
dir_abs = p.parent.absolute()  # Will return the executable directory absolute path

I'm pretty sure C-style casting syntax works in Objective C, so try that, too:

int myInt = (int) myFloat;

It might silence a compiler warning, at least.

In PHP you can use === and !== operators to check not only if the values are equal but also if their types match. So for example: 0 == false is true, but 0 === false is false. The same goes for != versus !==. Also in case you compare null to the other two using the mentioned operators, expect similar results.

Now in PHP this quality of values is usually used when returning a value which sometimes can be 0 (zero), but sometimes it might be that the function failed. In such cases in PHP you return false and you have to check for these cases using the identity operator ===. For example if you are searching for a position of one string inside the other and you're using strpos(), this function will return the numeric position which can be 0 if the string is found at the very beginning, but if the string is not found at all, then strpos() will return false and you have to take this into account when dealing with the result.

If you will use the same technique in your functions, anybody familiar with the standard PHP library will understand what is going on and how to check if the returned value is what is wanted or did some error occur while processing. The same actually goes for function params, you can process them differently depending on if they are arrays or strings or what not, and this technique is used throughout PHP heavily too, so everybody will get it quite easily. So I guess that's the power.

There is one link where it elaborated very well & solution is also given. Try it if you got proper solution please post here so other can understand. Given solution is ok then like the post so other can try these solution.

for you reference original link :- https://bensonxion.wordpress.com/2012/05/07/serializing-an-ienumerable-produces-collection-was-modified-enumeration-operation-may-not-execute/

When we use .Net Serialization classes to serialize an object where its definition contains an Enumerable type, i.e. collection, you will be easily getting InvalidOperationException saying "Collection was modified; enumeration operation may not execute" where your coding is under multi-thread scenarios. The bottom cause is that serialization classes will iterate through collection via enumerator, as such, problem goes to trying to iterate through a collection while modifying it.

First solution, we can simply use lock as a synchronization solution to ensure that the operation to the List object can only be executed from one thread at a time. Obviously, you will get performance penalty that if you want to serialize a collection of that object, then for each of them, the lock will be applied.

Well, .Net 4.0 which makes dealing with multi-threading scenarios handy. for this serializing Collection field problem, I found we can just take benefit from ConcurrentQueue(Check MSDN)class, which is a thread-safe and FIFO collection and makes code lock-free.

Using this class, in its simplicity, the stuff you need to modify for your code are replacing Collection type with it, use Enqueue to add an element to the end of ConcurrentQueue, remove those lock code. Or, if the scenario you are working on do require collection stuff like List, you will need a few more code to adapt ConcurrentQueue into your fields.

BTW, ConcurrentQueue doesnât have a Clear method due to underlying algorithm which doesnât permit atomically clearing of the collection. so you have to do it yourself, the fastest way is to re-create a new empty ConcurrentQueue for a replacement.

Have you tried sp_help?

In my case, I could solve this in an easier way. I opened the x.dtsConfig archive, and for an unknown reason this archive was not in the standard format, so ssis could not recognize the configurations. Fortunately, I had backed up the archive previously, so I just had to copy it to the original folder, and everything was working again.

var string = "123456"
string = String(string.prefix(3)) //"123"
string = String(string.suffix(3)) //"456"

If you are reencoding in your ffmpeg command line, that may be the reason why it is CPU intensive. You need to simply copy the streams to the single container. Since I do not have your command line I cannot suggest a specific improvement here. Your acodec and vcodec should be set to copy is all I can say.

EDIT: On seeing your command line and given you have already tried it, this is for the benefit of others who come across the same question. The command:

ffmpeg -i rtsp://@192.168.241.1:62156 -acodec copy -vcodec copy c:/abc.mp4

will not do transcoding and dump the file for you in an mp4. Of course this is assuming the streamed contents are compatible with an mp4 (which in all probability they are).

As of docker-compose version 3 and later, you can just use the hostname key:

version: '3'
services:
  dns:
    hostname: 'your-name'

first install nodemailer

npm install nodemailer  --save

import in to js file

const nodemailer = require("nodemailer");

const smtpTransport = nodemailer.createTransport({
    service: "Gmail",
    auth: {
        user: "[email protected]",
        pass: "password"
    },
    tls: {
        rejectUnauthorized: false
    }
});






 const mailOptions = {
        from: "[email protected]",
        to: [email protected],
        subject: "Welcome to ",
        text: 'hai send from me'.
    };


    smtpTransport.sendMail(mailOptions, function (error, response) {
        if (error) {
            console.log(error);
        }
        else {
            console.log("mail sent");
        }
    });

working in my application

I had a similar situation and solved it like this:

WebElement webElement = driver.findElement(By.xpath(""));
webElement.sendKeys(Keys.TAB);
webElement.sendKeys(Keys.ENTER);

SELECT LEFT(Car, LEN(Car) - 1)
FROM (
    SELECT Car + ', '
    FROM Cars
    FOR XML PATH ('')
  ) c (Car)

You can also try background:none;border:0px to buttons.

also the css selectors are div#yes button{..} and div#no button{..} . hopes it helps

If you have a vector of names already,which there are several ways to create, you can easily use the subset function to keep or drop an object.

dat2 <- subset(dat, select = names(dat) %in% c(KEEP))

In this case KEEP is a vector of column names which is pre-created. For example:

#sample data via Brandon Bertelsen
df <- data.frame(a=rnorm(100),
                 b=rnorm(100),
                 c=rnorm(100),
                 d=rnorm(100),
                 e=rnorm(100),
                 f=rnorm(100),
                 g=rnorm(100))

#creating the initial vector of names
df1 <- as.matrix(as.character(names(df)))

#retaining only the name values you want to keep
KEEP <- as.vector(df1[c(1:3,5,6),])

#subsetting the intial dataset with the object KEEP
df3 <- subset(df, select = names(df) %in% c(KEEP))

Which results in:

In addition to @Bruno's answer, you need to supply the -name for alias, otherwise Tomcat will throw Alias name tomcat does not identify a key entry error

Sample Command: openssl pkcs12 -export -in localhost.crt -inkey localhost.key -out localhost.p12 -name localhost

If you are using ES6 (Babel) or TypeScript you can stub out the property using get and set accessors

export class SomeClassStub {
  getValueA = jasmine.createSpy('getValueA');
  setValueA = jasmine.createSpy('setValueA');
  get valueA() { return this.getValueA(); }
  set valueA(value) { this.setValueA(value); }
}

Then in your test you can check that the property is set with:

stub.valueA = 'foo';

expect(stub.setValueA).toHaveBeenCalledWith('foo');
