Whatsapp have its own API

    Intent sendIntent = new Intent("android.intent.action.MAIN");
                        sendIntent.setAction(Intent.ACTION_VIEW);
                        sendIntent.setPackage("com.whatsapp");
                        String url = "https://api.whatsapp.com/send?phone=" + "Phone with international format" + "&text=" + "your message";
                        sendIntent.setData(Uri.parse(url));
                        if(sendIntent.resolveActivity(context.getPackageManager()) != null){
                             startActivity(sendIntent);
                        }

Code updated check added for Activity is available or not.

I used placeholders so just follow along, as you might want to still keep the inheritance from the original style.

Before

<android.support.v7.widget.Toolbar
    android:id="@+id/toolBar"
    android:layout_width="match_parent"
    android:layout_height="?attr/actionBarSize"
    android:background="?attr/colorPrimary"
    android:elevation="4dp"
    android:theme="@style/{{originalBaseStyle}}"
    app:popupTheme="@style/ThemeOverlay.AppCompat.Light"/>

After:

styles.xml

<style name="{{yourToolbarStyle}}" parent="{{originalBaseStyle}}">
    <item name="android:textColorPrimary">@android:color/white</item>
    <item name="android:textColorSecondary">@android:color/white</item>
    <item name="actionMenuTextColor">@android:color/white</item>
    <item name="actionOverflowButtonStyle">@style/ActionButtonOverflowStyle</item>
    <item name="drawerArrowStyle">@style/DrawerArrowStyle</item>
</style>

Therefore

<android.support.v7.widget.Toolbar
    android:id="@+id/toolBar"
    android:layout_width="match_parent"
    android:layout_height="?attr/actionBarSize"
    android:background="?attr/colorPrimary"
    android:elevation="4dp"
    android:theme="@style/{{yourToolbarStyle}}"
    app:popupTheme="@style/ThemeOverlay.AppCompat.Light"/>

If you just want to apply new config you don't need to shut it down.

$ sudo service elasticsearch restart

But if you want to shut it down anyway:

$ sudo service elasticsearch stop

OR

$ sudo systemctl stop elasticsearch.service

$ sudo systemctl restart elasticsearch.service

Docker:

docker restart <elasticsearch-container-name or id>

 DataClassesDataContext dc = new DataClassesDataContext();

 FamilyDetail fd = dc.FamilyDetails.Single(p => p.UserId == 1);

 fd.FatherName=txtFatherName.Text;
        fd.FatherMobile=txtMobile.Text;
        fd.FatherOccupation=txtFatherOccu.Text;
        fd.MotherName=txtMotherName.Text;
        fd.MotherOccupation=txtMotherOccu.Text;
        fd.Phone=txtPhoneNo.Text;
        fd.Address=txtAddress.Text;
        fd.GuardianName=txtGardianName.Text;

        dc.SubmitChanges();

I don't think you want to do this. The correct way to use a try statement in general is as precisely as possible. I think it would be better to do:

try:
    do_smth1()
except Stmnh1Exception:
    # handle Stmnh1Exception

try:
    do_smth2()
except Stmnh2Exception:
    # handle Stmnh2Exception

Objective-C is not Java. In Objective-C exceptions are what they are called. Exceptions! Don’t use them for error handling. It’s not their proposal. Just check the length of the string before using characterAtIndex and everything is fine....

Swift 2.0:

  var navArray:Array = (self.navigationController?.viewControllers)!
  navArray.removeAtIndex(navArray.count-2)
  self.navigationController?.viewControllers = navArray

The functions getElementById and getElementsByClassName are very specific, while querySelector and querySelectorAll are more elaborate. My guess is that they will actually have a worse performance.

Also, you need to check for the support of each function in the browsers you are targetting. The newer it is, the higher probability of lack of support or the function being "buggy".

I want to open external storage directory path for saving file programatically.I tried but not getting sdcard path. How can i do this?is there any solution for this??

To store your app files in SD card, you should use File[] getExternalFilesDirs (String type) method in Context class. Generally, second returned path would be the storage path for microSD card (if any).

On my phone, second path returned was /storage/sdcard1/Android/data/your.application.package.appname/files after passing null as argument to getExternalFilesDirs (String type). But path may vary on different phones, different Android versions.

Both File getExternalStorageDirectory () and File getExternalStoragePublicDirectory (String type) in Environment class may return SD card directory or internal memory directory depending on your phone's model and Android OS version.

Because According to Official Android Guide external storage can be

removable storage media (such as an SD card) or an internal (non-removable) storage.

The Internal and External Storage terminology according to Google/official Android docs is quite different from what we think.

I've run into issues with Webclient.Downloadstring before. If you do, you can try this:

WebRequest request = WebRequest.Create("http://www.google.com");
WebResponse response = request.GetResponse();
Stream data = response.GetResponseStream();
string html = String.Empty;
using (StreamReader sr = new StreamReader(data))
{
    html = sr.ReadToEnd();
}

I actual ran into the same requirement. I simply used CSS override like this

.navbar .btn-toolbar { margin-top: 0; margin-bottom: 0 }

Most easiest way in a single line of code

var base64Image = new Buffer( blob, 'binary' ).toString('base64');

You do not need to call d.keys(), so

if key not in d:
    d[key] = value

is enough. There is no clearer, more readable method.

You could update again with dict.get(), which would return an existing value if the key is already present:

d[key] = d.get(key, value)

but I strongly recommend against this; this is code golfing, hindering maintenance and readability.

SELECT Grade, GradeCount / SUM(GradeCount)
FROM (SELECT Grade, COUNT(*) As GradeCount
      FROM myTable
      GROUP BY Grade) Grades

you can use && and write all conditions in to the same where clause, or you can .Where().Where().Where()... and so on.

Safety check to only select if an item is matched.

//try to find item in list.  
ListItem oItem = DDL.Items.FindByValue("PassedValue"));
//if exists, select it.
if (oItem != null) oItem.Selected = true;

Simply you can write the following code snippet to convert an OpenCV image into a grey scale image

import cv2
image = cv2.imread('image.jpg',0)
cv2.imshow('grey scale image',image)

Observe that the image.jpg and the code must be saved in same folder.

Note that:

• ('image.jpg') gives a RGB image
• ('image.jpg',0) gives Grey Scale Image.

Code for set background color, for SolidColor:

button.Background = new SolidColorBrush(Color.FromArgb(Avalue, rValue, gValue, bValue));

int min = 65;
int max = 80;

Random r = new Random();
int i1 = r.nextInt(max - min + 1) + min;

Note that nextInt(int max) returns an int between 0 inclusive and max exclusive. Hence the +1.

All the highlighted solutions are using recursion (which is performance costly). Here is cleaner way without recursion:

public T GetControlByType<T>(Control root, Func<T, bool> predicate = null) where T : Control 
{
    if (root == null) {
        throw new ArgumentNullException("root");
    }

    var stack = new Stack<Control>(new Control[] { root });

    while (stack.Count > 0) {
        var control = stack.Pop();
        T match = control as T;

        if (match != null && (predicate == null || predicate(match))) {
            return match;
        }

        foreach (Control childControl in control.Controls) {
           stack.Push(childControl);
        }
    }

    return default(T);
}

Use set(CMAKE_RUNTIME_OUTPUT_DIRECTORY "/some/full/path/to/bin")

gradle supports ndk compilation by generating another Android.mk file with absolute paths to your sources. NDK supports absolute paths since r9 on OSX, r9c on Windows, so you need to upgrade your NDK to r9+.

You may run into other troubles as NDK support by gradle is preliminary. If so you can deactivate the ndk compilation from gradle by setting:

sourceSets.main {
    jni.srcDirs = []
    jniLibs.srcDir 'src/main/libs'
}

to be able to call ndk-build yourself and integrate libs from libs/.

btw, you have any issue compiling for x86 ? I see you haven't included it in your APP_ABI.

You can strip strings in Bash alone:

$ foo="Here is a String"
$ foo=${foo##*Here }
$ echo "$foo"
is a String
$ foo=${foo%% String*}
$ echo "$foo"
is a
$

And if you have a GNU grep that includes PCRE, you can use a zero-width assertion:

$ echo "Here is a String" | grep -Po '(?<=(Here )).*(?= String)'
is a

How about using a simple loop to count the occurrences of number of spaces!?

txt = "Just an example here move along" _x000D_
count = 1_x000D_
for i in txt:_x000D_
if i == " ":_x000D_
   count += 1_x000D_
print(count)

Download java jdk<version>-linux-x64.tar.gz file from https://www.oracle.com/technetwork/java/javase/downloads/index.html.

Extract this file where you want. like: /home/java(Folder name created by user in home directory).

Now open terminal. Set path JAVA_HOME=path of your jdk folder(open jdk folder then right click on any folder, go to properties then copy the path using select all) and paste here.

Like: JAVA_HOME=/home/xxxx/java/JDK1.8.0_201

Let Ubuntu know where our JDK/JRE is located.

sudo update-alternatives --install /usr/bin/java java /home/xxxx/java/jdk1.8.0_201/bin/java 20000
sudo update-alternatives --install /usr/bin/javac javac /home/xxxx/java/jdk1.8.0_201/bin/javac 20000
sudo update-alternatives --install /usr/bin/javaws javaws /home/xxxx/java/jdk1.8.0_201/bin/javaws 20000

Tell Ubuntu that our installation i.e., jdk1.8.0_05 must be the default Java.

sudo update-alternatives --set java /home/xxxx/sipTest/jdk1.8.0_201/bin/java
sudo update-alternatives --set javac /home/xxxx/java/sipTest/jdk1.8.0_201/bin/javac
sudo update-alternatives --set javaws /home/xxxxx/sipTest/jdk1.8.0_201/bin/javaws

Now try:

$ sudo update-alternatives --config java

There are 3 choices for the alternative java (providing /usr/bin/java).

  Selection    Path                                  Priority   Status
------------------------------------------------------------
* 0            /usr/lib/jvm/java-6-oracle1/bin/java   1047      auto mode
  1            /usr/bin/gij-4.6                       1046      manual mode
  2            /usr/lib/jvm/java-6-oracle1/bin/java   1047      manual mode
  3            /usr/lib/jvm/jdk1.7.0_75/bin/java      1         manual mode

Press enter to keep the current choice [*], or type selection number: 3

update-alternatives: using /usr/lib/jvm/jdk1.7.0_75/bin/java to provide /usr/bin/java (java) in manual mode

Repeat the above for:

sudo update-alternatives --config javac
sudo update-alternatives --config javaws

You could also use a core dump and then examine it with gdb. To get useful information you also need to compile with the -g flag.

Whenever you get the message:

 Segmentation fault (core dumped)

a core file is written into your current directory. And you can examine it with the command

 gdb your_program core_file

The file contains the state of the memory when the program crashed. A core dump can be useful during the deployment of your software.

Make sure your system doesn't set the core dump file size to zero. You can set it to unlimited with:

ulimit -c unlimited

Careful though! that core dumps can become huge.

The value is the same even though the printed representation is not what you expect:

decimal d = (decimal )1200.00;
Console.WriteLine(Decimal.Parse("1200") == d); //True

For @Joe above, "This is giving me a redirect loop. Before I added the code it worked fine. Any suggestions? – Joe Nov 8 '11 at 4:13"

This was happening to me as well and what I believe was happening is that there was a load balancer terminating the SSL request in front of the Web server. So, my Web site was always thinking the request was "http", even if the original browser requested it to be "https".

I admit this is a bit hacky, but what worked for me was to implement a "JustRedirected" property that I could leverage to figure out the person was already redirected once. So, I test for specific conditions that warrant the redirect and, if they are met, I set this property (value stored in session) prior to the redirection. Even if the http/https conditions for redirection are met the second time, I bypass the redirection logic and reset the "JustRedirected" session value to false. You'll need your own conditional test logic, but here's a simple implementation of the property:

    public bool JustRedirected
    {
        get
        {
            if (Session[RosadaConst.JUSTREDIRECTED] == null)
                return false;

            return (bool)Session[RosadaConst.JUSTREDIRECTED];
        }
        set
        {
            Session[RosadaConst.JUSTREDIRECTED] = value;
        }
    }

A one liner:

perl -pi.back -e 's/<PREF>/ABCD/g;' inputfile

As long as you go into the IIS configuration and change the default location from %SystemDrive%\InetPub to %SystemDrive%\www for each of the services (web, ftp) there shouldn't be any problems. Of course, you can't protect against other applications that might install stuff into that directory by default, instead of checking the configuration.

My recommendation? Don't change it -- it's not that hard to live with, and it reduces the confusion level for the next person who has to administrate the machine.

Google has announced support for tensorflow on Windows. Please follow instructions at https://developers.googleblog.com/2016/11/tensorflow-0-12-adds-support-for-windows.html. Please note CUDA8.0 is needed for GPU installation.

If you have installed the 64-bit version of Python 3.5 (either from Python.org or Anaconda), you can install TensorFlow with a single command: C:> pip install tensorflow

For GPU support, if you have CUDA 8.0 installed, you can install the following package instead: C:> pip install tensorflow-gpu

If you want to unit test code then you need to isolate your code you want to test (in this case your service) from external resources (e.g. databases). You could probably do this with some sort of in-memory EF provider, however a much more common way is to abstract away your EF implementation e.g. with some sort of repository pattern. Without this isolation any tests you write will be integration tests, not unit tests.

As for testing EF code - I write automated integration tests for my repositories that write various rows to the database during their initialization, and then call my repository implementations to make sure that they behave as expected (e.g. making sure that results are filtered correctly, or that they are sorted in the correct order).

These are integration tests not unit tests, as the tests rely on having a database connection present, and that the target database already has the latest up-to-date schema installed.

Also check this answer from here: Cannot manually edit applicationhost.config

The answer is simple, if not that obvious: win2008 is 64bit, notepad++ is 32bit. When you navigate to Windows\System32\inetsrv\config using explorer you are using a 64bit program to find the file. When you open the file using using notepad++ you are trying to open it using a 32bit program. The confusion occurs because, rather than telling you that this is what you are doing, windows allows you to open the file but when you save it the file's path is transparently mapped to Windows\SysWOW64\inetsrv\Config.

So in practice what happens is you open applicationhost.config using notepad++, make a change, save the file; but rather than overwriting the original you are saving a 32bit copy of it in Windows\SysWOW64\inetsrv\Config, therefore you are not making changes to the version that is actually used by IIS. If you navigate to the Windows\SysWOW64\inetsrv\Config you will find the file you just saved.

How to get around this? Simple - use a 64bit text editor, such as the normal notepad that ships with windows.

Add the key View controller-based status bar appearance to Info.plist file and make it boolean type set to NO.

Insert one line code in viewDidLoad (this works on specific class where it is mentioned)

 [UIApplication sharedApplication].statusBarStyle = UIStatusBarStyleLightContent;

Use this regular expression to match square brackets or single quotes:

/[\[\]']+/g

Replace with the empty string.

console.log("['abc','xyz']".replace(/[\[\]']+/g,''));

If your center content is deep inside other divs then only margin can save you. Nothing else. I face it always when not using a framework like Bootstrap.

This can happen for more than one reason. In my case this happened due to a permissions issue. The user that the task was running as didn't have permission to write to the logs directory so it failed with this error.

Surely the best way is to avoid doing any heavy HTML creation in your JavaScript at all? The markup sent down from the server ought to contain the bulk of it, which you can then manipulate, using CSS rather than brute force removing/replacing elements, if at all possible.

This doesn't apply if you're doing something "clever" like emulating a widget system.

Here's a tidyverse version:

library(tidyverse)
data(diamonds)

(as.data.frame(table(diamonds$cut)) %>% rename(Count=1,Freq=2) %>% mutate(Perc=100*Freq/sum(Freq)))

Or if you want a handy function:

getPercentages <- function(df, colName) {
  df.cnt <- df %>% select({{colName}}) %>% 
    table() %>%
    as.data.frame() %>% 
    rename({{colName}} :=1, Freq=2) %>% 
    mutate(Perc=100*Freq/sum(Freq))
}

Now you can do:

diamonds %>% getPercentages(cut)

or this:

df=diamonds %>% group_by(cut) %>% group_modify(~.x %>% getPercentages(clarity))

I have Far.exe as the first item in the start menu.

Richtext in the clipboard ->

ctrl-escape,arrdown,enter,shift-f4,$,enter
shift-insert,ctrl-insert,alt-backspace,
f10,enter

-> plaintext in the clipboard

Pros: no mouse, just blind typing, ends exactly where i was before

Cons: ANSI encoding - international symbols are lost

Luckily, I do not have to do that too often :)

This error is because of using more number of libraries.in my case 'compile 'com.google.android.gms:play-services-9.4.0' caused this error.To avoid this error use necessary libraries.for example if you want to use Maps in your app.Then use compile 'com.google.android.gms:play-services-maps:9.4.0'.while adding google play services dependency specify the needed libraries only.by default it includes all the libraries.

For the instance of

render :json => @projects, :include => :tasks

You are stating that you want to render @projects as JSON, and include the association tasks on the Project model in the exported data.

For the instance of

render :json => @projects, :callback => 'updateRecordDisplay'

You are stating that you want to render @projects as JSON, and wrap that data in a javascript call that will render somewhat like:

updateRecordDisplay({'projects' => []})

This allows the data to be sent to the parent window and bypass cross-site forgery issues.

Here is function which replaces url param with paramVal

function updateURLParameter(url, param, paramVal){
        if(!url.includes('?')){
            return url += '?' + param + '=' + paramVal;
        }else if(!url.includes(param)){
            return url += '&' + param + '=' + paramVal;
        }else {
            let paramStartIndex = url.search(param);
            let paramEndIndex = url.indexOf('&', paramStartIndex);
            if (paramEndIndex == -1){
                paramEndIndex = url.length;
            }
            let brands = url.substring(paramStartIndex, paramEndIndex);
    
            return url.replace(brands, param + '=' + paramVal);
        }
    }

I've found the same problem. I lost almost a day trying to start a service from OnClickListener method - outside the onCreate and after 1 day, I still failed!!!! Very frustrating! I was looking at the sample example RemoteServiceController. Theirs works, but my implementation does not work!

The only way that was working for me, was from inside onCreate method. None of the other variants worked and believe me I've tried them all.

Conclusion:

• If you put your service class in different package than the mainActivity, I'll get all kind of errors

• Also the one "/" couldn't find path to the service, tried starting with Intent(package,className) and nothing , also other type of Intent starting

• I moved the service class in the same package of the activity Final form that works

• Hopefully this helps someone by defining the listerners onClick inside the onCreate method like this:

  public void onCreate() {
  //some code......
      Button btnStartSrv  = (Button)findViewById(R.id.btnStartService);
      Button btnStopSrv  = (Button)findViewById(R.id.btnStopService);
  
      btnStartSrv.setOnClickListener(new OnClickListener() {
          public void onClick(View v) {
              startService(new Intent("RM_SRV_AIDL"));
          }
      });
  
      btnStopSrv.setOnClickListener(new OnClickListener() {
          public void onClick(View v) {
              stopService(new Intent("RM_SRV_AIDL"));
          }
      });
  
  } // end onCreate
  

Also very important for the Manifest file, be sure that service is child of application:

<application ... >
    <activity ... >
     ...
    </activity>
    <service
        android:name="com.mainActivity.MyRemoteGPSService"
        android:label="GPSService"
        android:process=":remote">

        <intent-filter>
             <action android:name="RM_SRV_AIDL" />
        </intent-filter>
    </service>
</application>

You can use the SO_RCVTIMEO and SO_SNDTIMEO socket options to set timeouts for any socket operations, like so:

    struct timeval timeout;      
    timeout.tv_sec = 10;
    timeout.tv_usec = 0;

    if (setsockopt (sockfd, SOL_SOCKET, SO_RCVTIMEO, (char *)&timeout,
                sizeof(timeout)) < 0)
        error("setsockopt failed\n");

    if (setsockopt (sockfd, SOL_SOCKET, SO_SNDTIMEO, (char *)&timeout,
                sizeof(timeout)) < 0)
        error("setsockopt failed\n");

Edit: from the setsockopt man page:

SO_SNDTIMEO is an option to set a timeout value for output operations. It accepts a struct timeval parameter with the number of seconds and microseconds used to limit waits for output operations to complete. If a send operation has blocked for this much time, it returns with a partial count or with the error EWOULDBLOCK if no data were sent. In the current implementation, this timer is restarted each time additional data are delivered to the protocol, implying that the limit applies to output portions ranging in size from the low-water mark to the high-water mark for output.

SO_RCVTIMEO is an option to set a timeout value for input operations. It accepts a struct timeval parameter with the number of seconds and microseconds used to limit waits for input operations to complete. In the current implementation, this timer is restarted each time additional data are received by the protocol, and thus the limit is in effect an inactivity timer. If a receive operation has been blocked for this much time without receiving additional data, it returns with a short count or with the error EWOULDBLOCK if no data were received. The struct timeval parameter must represent a positive time interval; otherwise, setsockopt() returns with the error EDOM.

You can use result emitted from previous Observable thanks to mergeMap (or his alias flatMap) operator like this:

 const one = Observable.of('https://api.github.com/users');
 const two = (c) => ajax(c);//ajax from Rxjs/dom library

 one.mergeMap(two).subscribe(c => console.log(c))

SELECT * FROM Employee Emp1 
WHERE (N-1) = ( 
    SELECT COUNT(DISTINCT(Emp2.Salary)) 
    FROM  Employee Emp2 
    WHERE Emp2.Salary > Emp1.Salary)

For each record processed by outer query, inner query will be executed and will return how many records has records has salary less than the current salary. If you are looking for second highest salary then your query will stop as soon as inner query will return N-1.

• The NVARCHAR2 stores variable-length character data. When you create a table with the NVARCHAR2 column, the maximum size is always in character length semantics, which is also the default and only length semantics for the NVARCHAR2 data type.

  The NVARCHAR2data type uses AL16UTF16character set which encodes Unicode data in the UTF-16 encoding. The AL16UTF16 use 2 bytes to store a character. In addition, the maximum byte length of an NVARCHAR2 depends on the configured national character set.

• VARCHAR2 The maximum size of VARCHAR2 can be in either bytes or characters. Its column only can store characters in the default character set while the NVARCHAR2 can store virtually any characters. A single character may require up to 4 bytes.

By defining the field as:

• VARCHAR2(10 CHAR) you tell Oracle it can use enough space to store 10 characters, no matter how many bytes it takes to store each one. A single character may require up to 4 bytes.
• NVARCHAR2(10) you tell Oracle it can store 10 characters with 2 bytes per character

In Summary:

• VARCHAR2(10 CHAR) can store maximum of 10 characters and maximum of 40 bytes (depends on the configured national character set).

• NVARCHAR2(10) can store maximum of 10 characters and maximum of 20 bytes (depends on the configured national character set).

Note: Character set can be UTF-8, UTF-16,....

Please have a look at this tutorial for more detail.

Have a good day!

Here Value 1 to 10 are column names that you are getting

Just an observation. The input is a list of lists, but the output from the very nice solution: rotated = zip(*original[::-1]) returns a list of tuples.

This may or may not be an issue.

It is, however, easily corrected:

original = [[1, 2, 3],
            [4, 5, 6],
            [7, 8, 9]
            ]


def rotated(array_2d):
    list_of_tuples = zip(*array_2d[::-1])
    return [list(elem) for elem in list_of_tuples]
    # return map(list, list_of_tuples)

print(list(rotated(original)))

# [[7, 4, 1], [8, 5, 2], [9, 6, 3]]

The list comp or the map will both convert the interior tuples back to lists.

Here's a future-proof approach.

Combining @CamHart's and @Yuval's suggestions with @RoshOxymoron's accepted answer has the benefit of avoiding:

• _hidden and potentially deprecated methods
• indexing into the stack (which could be reordered in future pythons)

So I think this plays nice with future python versions (tested on 2.7.3 and 3.3.2):

from __future__ import print_function
import inspect

def bar():
    print("my name is '{}'".format(inspect.currentframe().f_code.co_name))

Step 1:

select object_name, s.sid, s.serial#, p.spid 
from v$locked_object l, dba_objects o, v$session s, v$process p
where l.object_id = o.object_id and l.session_id = s.sid and s.paddr = p.addr;

Step 2:

alter system kill session 'sid,serial#'; --`sid` and `serial#` get from step 1

  (err) => console.log(err),

);

Here's a solution that doesn't use negative margins or calc. Run the snippet below to see the final result.

Explanation

We give the header and the footer a fixed height of 30px and position them absolutely at the top and bottom, respectively. To prevent the content from falling underneath, we use two classes: below-header and above-footer to pad the div above and below with 30px.

All of the content is wrapped in a position: relative div so that the header and footer are at the top/bottom of the content and not the window.

We use the classes fit-to-parent and min-fit-to-parent to make the content fill out the page. This gives us a sticky footer which is at least as low as the window, but hidden if the content is longer than the window.

Inside the header and footer, we use the display: table and display: table-cell styles to give the header and footer some vertical padding without disrupting the shrink-wrap quality of the page. (Giving them real padding can cause the total height of the page to be more than 100%, which causes a scroll bar to appear when it isn't really needed.)

Just add position, right and top to your class .close-image

.close-image {
    cursor: pointer;
    display: block;
    float: right;  
    z-index: 3;
    position: absolute; /*newly added*/
    right: 5px; /*newly added*/
    top: 5px;/*newly added*/
}

Give a style inside the td element or in your scss file, like this:

vertical-align: 
    middle;

First, check your git version by using this command

git version

Then follow the case according to your git version

Three cases:

1. If your git version is 2.14.1 or earlier:
   

   Uninstall the git, download the latest git, and install it again.

2. And versions between 2.14.2 and 2.16.1:
   

   Use command git update

3. If the version is equal to or greater than Git 2.16.1(2):
   

   Use command git update-git-for-windows

You have to add the following dependency to your build:

<dependency>
    <groupId>org.openrdf.sesame</groupId>
    <artifactId>sesame-rio-api</artifactId>
    <version>2.7.2</version>
</dependency>

Furthermore i would suggest to take a deep look into the documentation about how to use the lib.

According to the HTML5 CR, which requires continued support to “obsolete” features, too, the align=center attribute is rather tricky. Rendering rules for tables say: td elements with that attribute “are expected to center text within themselves, as if they had their 'text-align' property set to 'center' in a presentational hint, and to align descendants to the center.”

And aligning descendants is defined as so that a browser will “align only those descendants that have both their 'margin-left' and 'margin-right' properties computing to a value other than 'auto', that are over-constrained and that have one of those two margins with a used value forced to a greater value, and that do not themselves have an applicable align attribute. When multiple elements are to align a particular descendant, the most deeply nested such element is expected to override the others. Aligned elements are expected to be aligned by having the used values of their left and right margins be set accordingly.”

So it really depends on the content.

If the replacement character can be '?' instead of a space, then I'd suggest result = text.encode('ascii', 'replace').decode():

"""Test the performance of different non-ASCII replacement methods."""


import re
from timeit import timeit


# 10_000 is typical in the project that I'm working on and most of the text
# is going to be non-ASCII.
text = 'Æ' * 10_000


print(timeit(
    """
result = ''.join([c if ord(c) < 128 else '?' for c in text])
    """,
    number=1000,
    globals=globals(),
))

print(timeit(
    """
result = text.encode('ascii', 'replace').decode()
    """,
    number=1000,
    globals=globals(),
))

Results:

Dim Wb As Excel.Workbook
Set Wb = Workbooks.Open(file_path)
Wb.Sheets("Sheet1").Cells(2,24).Value = 24
Wb.Close

To know the sheets name to refer in Wb.Sheets("sheetname") you can use the following :

Dim sht as Worksheet    
For Each sht In tempWB.Sheets
    Debug.Print sht.Name
Next sht

This works:

any(c.isalpha() for c in 'string')

in my case, some characters like " , :"'{}[] " maybe corrupt the JSON format, so use try json.loads(str) except to check your input

First, make sure you understand, if you need to use Secure FTP (=FTPS, as per your text) or SFTP (as per tag you have used).

Neither is supported by Windows command-line ftp.exe. As you have suggested, you can use WinSCP. It supports both FTPS and SFTP.

Using WinSCP, your batch file would look like (for SFTP):

echo open sftp://ftp_user:[email protected] -hostkey="server's hostkey" >> ftpcmd.dat
echo put c:\directory\%1-export-%date%.csv >> ftpcmd.dat
echo exit >> ftpcmd.dat
winscp.com /script=ftpcmd.dat
del ftpcmd.dat

And the batch file:

winscp.com /log=ftpcmd.log /script=ftpcmd.dat /parameter %1 %date%

Though using all capabilities of WinSCP (particularly providing commands directly on command-line and the %TIMESTAMP% syntax), the batch file simplifies to:

winscp.com /log=ftpcmd.log /command ^
    "open sftp://ftp_user:[email protected] -hostkey=""server's hostkey""" ^
    "put c:\directory\%1-export-%%TIMESTAMP#yyyymmdd%%.csv" ^
    "exit"

For the purpose of -hostkey switch, see verifying the host key in script.

Easier than assembling the script/batch file manually is to setup and test the connection settings in WinSCP GUI and then have it generate the script or batch file for you:

All you need to tweak is the source file name (use the %TIMESTAMP% syntax as shown previously) and the path to the log file.

For FTPS, replace the sftp:// in the open command with ftpes:// (explicit TLS/SSL) or ftps:// (implicit TLS/SSL). Remove the -hostkey switch.

winscp.com /log=ftpcmd.log /command ^
    "open ftps://ftp_user:[email protected] -explicit" ^
    "put c:\directory\%1-export-%%TIMESTAMP#yyyymmdd%%.csv" ^
    "exit"

You may need to add the -certificate switch, if your server's certificate is not issued by a trusted authority.

Again, as with the SFTP, easier is to setup and test the connection settings in WinSCP GUI and then have it generate the script or batch file for you.

See a complete conversion guide from ftp.exe to WinSCP.

You should also read the Guide to automating file transfers to FTP server or SFTP server.

Note to using %TIMESTAMP#yyyymmdd% instead of %date%: A format of %date% variable value is locale-specific. So make sure you test the script on the same locale you are actually going to use the script on. For example on my Czech locale the %date% resolves to ct 06. 11. 2014, what might be problematic when used as a part of a file name.

For this reason WinSCP supports (locale-neutral) timestamp formatting natively. For example %TIMESTAMP#yyyymmdd% resolves to 20170515 on any locale.

(I'm the author of WinSCP)

<h1>
print me
</h1>
<h1 class="noPrint">
no print
</h1>
<button onclick="window.print();" class="noPrint">
Print Me
</button>

I came across another elegant solution for this:

Place your printable part inside a div with an id like this:

<div id="printableArea">
      <h1>Print me</h1>
</div>

<input type="button" onclick="printDiv('printableArea')" value="print a div!" />

Now let's create a really simple javascript:

function printDiv(divName) {
     var printContents = document.getElementById(divName).innerHTML;
     var originalContents = document.body.innerHTML;

     document.body.innerHTML = printContents;

     window.print();

     document.body.innerHTML = originalContents;
}

SOURCE : SO Answer

Write a program to accept two integers and output the largest of two numbers to a file at a location of your choice. Now describe what each statement does.

It's possible to drill down pretty deep starting from the significance of the import statement, right down to abnormal termination

The JLabel background is transparent by default. Set the opacity at true like that:

label.setOpaque(true);

@echo off & setlocal EnableDelayedExpansion
set Var=finding the length of strings
for /l %%A in (0,1,10000) do if not "%Var%"=="!Var:~0,%%A!" (set /a Length+=1) else (echo !Length! & pause & exit /b)

set the var to whatever you want to find the length of it or change it to set /p var= so that the user inputs it. Putting this here for future reference.

+= is just a shortcut for writing

number = 4
number = number + 1

So instead you would write

numbers = 4
numbers += 1

Both ways are correct but example two helps you write a little less code

    print('\tLength of Letters enum:', len(Letters))

    print('\nUsing a list to create Enum:')
    Letters = Enum(list('abcde'))
    a = Letters.a
    print('\tIs a in e?', a in Letters)
    print('\tIs 54 in e?', 54 in Letters)
    print('\tLength of Letters enum:', len(Letters))

    try:
        # make sure we raise an exception if we pass an invalid arg
        Failure = Enum('This is a Failure')
        print('Failure')
    except EnumTypeError:
        print('Success!')

Output:

Using a dictionary to create Enum:
        Is a in e? True
        Is 54 in e? False
        Length of Letters enum: 5

Using a list to create Enum:
        Is a in e? True
        Is 54 in e? False
        Length of Letters enum: 5
Success!

In IntelliJ you can specify default settings for each run configuration. In Run/Debug configuration dialog (the one you use to configure heap per test) click on Defaults and JUnit. These settings will be automatically applied to each new JUnit test configuration. I guess similar setting exists for Eclipse.

However there is no simple option to transfer such settings (at least in IntelliJ) across environments. You can commit IntelliJ project files to your repository: it might work, but I do not recommend it.

You know how to set these for maven-surefire-plugin. Good. This is the most portable way (see Ptomli's answer for an example).

For the rest - you must remember that JUnit test cases are just a bunch of Java classes, not a standalone program. It is up to the runner (let it be a standalone JUnit runner, your IDE, maven-surefire-plugin to set those options. That being said there is no "portable" way to set them, so that memory settings are applied irrespective to the runner.

To give you an example: you cannot define Xmx parameter when developing a servlet - it is up to the container to define that. You can't say: "this servlet should always be run with Xmx=1G.

You can use embed player with opacity over on a cover photo with a right positioned play icon. After this you can check the activeElement of your document.

Of course I know this is not an optimal solution, but works on mobile devices too.

<div style="position: relative;">
   <img src="http://s3.amazonaws.com/content.newsok.com/newsok/images/mobile/play_button.png" style="position:absolute;top:0;left:0;opacity:1;" id="cover">
   <iframe width="560" height="315" src="https://www.youtube.com/embed/2qhCjgMKoN4?controls=0" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in- picture" allowfullscreen style="position: absolute;top:0;left:0;opacity:0;" id="player"></iframe>
 </div>
 <script>
   setInterval(function(){
      if(document.activeElement instanceof HTMLIFrameElement){
         document.getElementById('cover').style.opacity=0;
         document.getElementById('player').style.opacity=1;
       }
    } , 50);
  </script>

But here's the rub, sometimes you can't or don't want to wait. For example I want to use the new support for RubyMotion which includes RubyMotion project structure support, setup of rake files, setup of configurations that are hooked to iOS Simulator etc.

RubyMine has all of these now, IDEA does not. So I would have to generate a RubyMotion project outside of IDEA, then setup an IDEA project and hook up to that source folder etc and God knows what else.

What JetBrains should do is have a licensing model that would allow me, with the purchase of IDEA to use any of other IDEs, as opposed to just relying on IDEAs plugins.

I would be willing to pay more for that i.e. say 50 bucks more for said flexibility.

The funny thing is, I was originally a RubyMine customer that upgraded to IDEA, because I did want that polyglot setup. Now I'm contemplating paying for the upgrade of RubyMine, just because I need to do RubyMotion now. Also there are other potential areas where this out of sync issue might bite me again . For example torque box workflow / deployment support.

JetBrains has good IDEs but I guess I'm a bit annoyed.

To read the file saved in assets folder

public static String readFromFile(Context context, String file) {
        try {
            InputStream is = context.getAssets().open(file);
            int size = is.available();
            byte buffer[] = new byte[size];
            is.read(buffer);
            is.close();
            return new String(buffer);
        } catch (Exception e) {
            e.printStackTrace();
            return "" ;
        }
    }

timeboard package does this.

Suppose your date is 04 Sep 2017. In spite of being a Monday, it was a holiday in the US (the Labor Day). So, the most recent business day was Friday, Sep 1.

>>> import timeboard.calendars.US as US
>>> clnd = US.Weekly8x5()
>>> clnd('04 Sep 2017').rollback().to_timestamp().date()
datetime.date(2017, 9, 1)

In UK, 04 Sep 2017 was the regular business day, so the most recent business day was itself.

>>> import timeboard.calendars.UK as UK
>>> clnd = UK.Weekly8x5()
>>> clnd('04 Sep 2017').rollback().to_timestamp().date()
datetime.date(2017, 9, 4)

The best way of searching for users is (sAMAccountType=805306368).

Or for disabled users:

(&(sAMAccountType=805306368)(userAccountControl:1.2.840.113556.1.4.803:=2))

Or for active users:

(&(sAMAccountType=805306368)(!(userAccountControl:1.2.840.113556.1.4.803:=2)))

I find LDAP as not being so light at it was supposed to be.

Also resource for common LDAP queries - trying to find them yourself and you will precious time and definitely make mistakes.

Regarding domains: it not possible in a single query because the domain is part of the user distinguisedName (DN) which, on Microsoft AD, is not searchable by partial matching.

You're getting into looping most likely due to these rules:

RewriteRule ^(.*\.php)$ $1 [L]
RewriteRule ^(wp-(content|admin|includes).*) $1 [L]

Just comment it out and try again in a new browser.

In addition to Michael's answer, consider a second way: adding linterOptions.exclude to tslint.json

For example, you may have tslint.json with following lines:

{
  "linterOptions": {
    "exclude": [
      "someDirectory/*.d.ts"
    ]
  }
}

You can use CFArray instead of NSArray. Here is an article explaining how.

CFMutableArrayRef ar = CFArrayCreateMutable(NULL, 0, NULL);
for (NSUInteger i = 0; i < 1000; i++)
{
  CFArrayAppendValue(ar, (void*)i);
}
CFRelease(ar); /* Releasing the array */

The same applies for the CoreFoundation version of the other containers too.

I just ran into this issue while working with Eclipse. In my case, I had the correct Hadoop version downloaded (hadoop-2.5.0-cdh5.3.0.tgz), I extracted the contents and placed it directly in my C drive. Then I went to

Eclipse->Debug/Run Configurations -> Environment (tab) -> and added

variable: HADOOP_HOME

Value: C:\hadoop-2.5.0-cdh5.3.0

Here's a method and some reasoning behind using it this way. It isn't as pretty to edit the stored proc but there are pros and cons...

UPDATE: You can also wrap this entire call in a TRANSACTION. Including many stored procedures in a single transaction which can all commit or all rollback. Another advantage of wrapping in a transaction is the stored procedure always exists for other SQL connections as long as they do not use the READ UNCOMMITTED transaction isolation level!

1) To avoid alters just as a process decision. Our processes are to always IF EXISTS DROP THEN CREATE. If you do the same pattern of assuming the new PROC is the desired proc, catering for alters is a bit harder because you would have an IF EXISTS ALTER ELSE CREATE.

2) You have to put CREATE/ALTER as the first call in a batch so you can't wrap a sequence of procedure updates in a transaction outside dynamic SQL. Basically if you want to run a whole stack of procedure updates or roll them all back without restoring a DB backup, this is a way to do everything in a single batch.

IF NOT EXISTS (select ss.name as SchemaName, sp.name as StoredProc 
    from sys.procedures sp
    join sys.schemas ss on sp.schema_id = ss.schema_id
    where ss.name = 'dbo' and sp.name = 'MyStoredProc')
BEGIN
    DECLARE @sql NVARCHAR(MAX)

    -- Not so aesthetically pleasing part. The actual proc definition is stored
    -- in our variable and then executed.
    SELECT @sql = 'CREATE PROCEDURE [dbo].[MyStoredProc]
(
@MyParam int
)
AS
SELECT @MyParam'
    EXEC sp_executesql @sql
END

SELECT COUNT(*) FROM (SELECT * FROM tbl WHERE id=1 UNION SELECT * FROM tbl WHERE id=2) a

If you got two rows, they different, if one - the same.

There is no easy way to do this. I needed this as well, but wanted a function that can take any two variables and test for equality. That includes non-object values, objects, arrays and any level of nesting.

In your question, you mention wanting to ignore the order of the values in an array. My solution doesn't inherently do that, but you can achieve it by sorting the arrays before comparing for equality

I also wanted the option of casting non-objects to strings so that [1,2]===["1",2]

Since my project uses UnderscoreJs, I decided to make it a mixin rather than a standalone function.

You can test it out on http://jsfiddle.net/nemesarial/T44W4/

Here is my mxin:

_.mixin({
  /**
  Tests for the equality of two variables
    valA: first variable
    valB: second variable
    stringifyStatics: cast non-objects to string so that "1"===1
  **/
  equal:function(valA,valB,stringifyStatics){
    stringifyStatics=!!stringifyStatics;

    //check for same type
    if(typeof(valA)!==typeof(valB)){
      if((_.isObject(valA) || _.isObject(valB))){
        return false;
      }
    }

    //test non-objects for equality
    if(!_.isObject(valA)){
      if(stringifyStatics){
        var valAs=''+valA;
        var valBs=''+valB;
        ret=(''+valA)===(''+valB);
      }else{
        ret=valA===valB;
      }
      return ret;
    }

    //test for length
    if(_.size(valA)!=_.size(valB)){
      return false;
    }

    //test for arrays first
    var isArr=_.isArray(valA);

    //test whether both are array or both object
    if(isArr!==_.isArray(valB)){
      return false;
    }

    var ret=true;
    if(isArr){
      //do test for arrays
      _.each(valA,function(val,idx,lst){
        if(!ret){return;}
        ret=ret && _.equal(val,valB[idx],stringifyStatics);
      });
    }else{
      //do test for objects
      _.each(valA,function(val,idx,lst){
        if(!ret){return;}

        //test for object member exists
        if(!_.has(valB,idx)){
          ret=false;
          return;
        }

        // test for member equality
        ret=ret && _.equal(val,valB[idx],stringifyStatics);
      });

    }
    return ret;
  }
});

This is how you use it:

_.equal([1,2,3],[1,2,"3"],true)

To demonstrate nesting, you can do this:

_.equal(
    ['a',{b:'b',c:[{'someId':1},2]},[1,2,3]],
    ['a',{b:'b',c:[{'someId':"1"},2]},["1",'2',3]]
,true);

Simply throw Exception if input is invalid

Scanner sc=new Scanner(System.in);
try
{
  System.out.println("Please input an integer");
  //nextInt will throw InputMismatchException
  //if the next token does not match the Integer
  //regular expression, or is out of range
  int usrInput=sc.nextInt();
}
catch(InputMismatchException exception)
{
  //Print "This is not an integer"
  //when user put other than integer
  System.out.println("This is not an integer");
}

Use SecurityElement.Escape

using System;
using System.Security;

class Sample {
  static void Main() {
    string text = "Escape characters : < > & \" \'";
    string xmlText = SecurityElement.Escape(text);
//output:
//Escape characters : &lt; &gt; &amp; &quot; &apos;
    Console.WriteLine(xmlText);
  }
}

Since you don't care which id to return I stick with MAX id for each email to simplify SQL query, give it a try

;WITH ue(id)
 AS
 (
   SELECT MAX(id)
   FROM table
   GROUP BY email
 )
 SELECT * FROM table t
 INNER JOIN ue ON ue.id = t.id

For Windows user 

1> Open command prompt.
2> Change the directory to destination folder (Where you want to store your project in local machine.)
3> Now go to project setting online(From where you want to clone)
4> Click on clone, and copy the clone command.
5> Now enter the same on cmd .

It will start cloning saving on the selected folder you given .

You can paste the following code to the console to scroll up/down using the a/z keyboard keys. If you want to set your own keys you can visit this page to get the keycodes

function KeyPress(e) {
  var evtobj = window.event? event : e
  if (evtobj.keyCode == 90) {
    window.scrollBy(0, 100) 
  }
  if (evtobj.keyCode == 65) {
    window.scrollBy(0, -100) 
  }
}

document.onkeydown = KeyPress;

Less than or equal:

User.objects.filter(userprofile__level__lte=0)

Greater than or equal:

User.objects.filter(userprofile__level__gte=0)

Likewise, lt for less than and gt for greater than. You can find them all in the documentation.

For any Swing component (that is, anything that extends JComponent), you can call the setToolTipText(String) method.

JodaTime's DateTimeFormat to rescue:

String dateString = "2010-03-01T00:00:00-08:00";
String pattern = "yyyy-MM-dd'T'HH:mm:ssZ";
DateTimeFormatter dtf = DateTimeFormat.forPattern(pattern);
DateTime dateTime = dtf.parseDateTime(dateString);
System.out.println(dateTime); // 2010-03-01T04:00:00.000-04:00

(time and timezone difference in toString() is just because I'm at GMT-4 and didn't set locale explicitly)

If you want to end up with java.util.Date just use DateTime#toDate():

Date date = dateTime.toDate();

Wait for JDK7 (JSR-310) JSR-310, the referrence implementation is called ThreeTen (hopefully it will make it into Java 8) if you want a better formatter in the standard Java SE API. The current SimpleDateFormat indeed doesn't eat the colon in the timezone notation.

Update: as per the update, you apparently don't need the timezone. This should work with SimpleDateFormat. Just omit it (the Z) in the pattern.

String dateString = "2010-03-01T00:00:00-08:00";
String pattern = "yyyy-MM-dd'T'HH:mm:ss";
SimpleDateFormat sdf = new SimpleDateFormat(pattern);
Date date = sdf.parse(dateString);
System.out.println(date); // Mon Mar 01 00:00:00 BOT 2010

(which is correct as per my timezone)

1. Check the user in /etc/nginx/nginx.conf
2. Change ownership to user.

sudo chown -R nginx:nginx /var/lib/nginx

Now see the magic.

I could do it using

from subprocess import Popen

process = Popen(command, shell=True)
Popen("TASKKILL /F /PID {pid} /T".format(pid=process.pid))

it killed the cmd.exe and the program that i gave the command for.

(On Windows)

For Kotlin, if you want to be sure that the format is "Aaaaaaaaa" you can use :

myString.toLowerCase(Locale.getDefault()).capitalize()

I believe you probably meant:

from __future__ import print_function

for song in json_object:
    # now song is a dictionary
    for attribute, value in song.items():
        print(attribute, value) # example usage

NB: You could use song.iteritems instead of song.items if in Python 2.

Another simple way you can do this is by adding a click event, through a class name to the anchor tags on the page to detect when it has been clicked, then you can now use the window.location.href to get the url data which you can use to run your ajax request to the server. Simple and Easy.

Submit your form like this ...

Your HTML code

    <form name="myform" action="handle-data.php"> Search: <input type='text' name='query' />
     <a href="javascript: submitform()">Search</a> 
   </form> 

JavaScript Code

  <script type="text/javascript"> 
        function submitform() {   document.myform.submit(); } 
   </script> 

Ok so there are many answers here and I dont think they answer your question which I think is similar to mine.

You need to do an operation like contacting a database or third part api that will take time and is asyncronus. You do not want to load the entire document into memory due to being to large or some other reason so you need to read line by line to process.

I have read into the fs documents and it can pause on reading but using .on('data') call will make it continous which most of these answer use and cause the problem.

UPDATE: I know more info about Streams than I ever wanted

The best way to do this is to create a writable stream. This will pipe the csv data into your writable stream which you can manage asyncronus calls. The pipe will manage the buffer all the way back to the reader so you will not wind up with heavy memory usage

Simple Version

const parser = require('csv-parser');
const stripBom = require('strip-bom-stream');
const stream = require('stream')

const mySimpleWritable = new stream.Writable({
  objectMode: true, // Because input is object from csv-parser
  write(chunk, encoding, done) { // Required
    // chunk is object with data from a line in the csv
    console.log('chunk', chunk)
    done();
  },
  final(done) { // Optional
    // last place to clean up when done
    done();
  }
});
fs.createReadStream(fileNameFull).pipe(stripBom()).pipe(parser()).pipe(mySimpleWritable)

Class Version

const parser = require('csv-parser');
const stripBom = require('strip-bom-stream');
const stream = require('stream')
// Create writable class
class MyWritable extends stream.Writable {
  // Used to set object mode because we get an object piped in from csv-parser
  constructor(another_variable, options) {
    // Calls the stream.Writable() constructor.
    super({ ...options, objectMode: true });
    // additional information if you want
    this.another_variable = another_variable
  }
  // The write method
  // Called over and over, for each line in the csv
  async _write(chunk, encoding, done) {
    // The chunk will be a line of your csv as an object
    console.log('Chunk Data', this.another_variable, chunk)

    // demonstrate await call
    // This will pause the process until it is finished
    await new Promise(resolve => setTimeout(resolve, 2000));

    // Very important to add.  Keeps the pipe buffers correct.  Will load the next line of data
    done();
  };
  // Gets called when all lines have been read
  async _final(done) {
    // Can do more calls here with left over information in the class
    console.log('clean up')
    // lets pipe know its done and the .on('final') will be called
    done()
  }
}

// Instantiate the new writable class
myWritable = new MyWritable(somevariable)
// Pipe the read stream to csv-parser, then to your write class
// stripBom is due to Excel saving csv files with UTF8 - BOM format
fs.createReadStream(fileNameFull).pipe(stripBom()).pipe(parser()).pipe(myWritable)

// optional
.on('finish', () => {
  // will be called after the wriables internal _final
  console.log('Called very last')
})

OLD METHOD:

PROBLEM WITH readable

const csv = require('csv-parser');
const fs = require('fs');

const processFileByLine = async(fileNameFull) => {

  let reading = false

  const rr = fs.createReadStream(fileNameFull)
  .pipe(csv())

  // Magic happens here
  rr.on('readable', async function(){
    // Called once when data starts flowing
    console.log('starting readable')

    // Found this might be called a second time for some reason
    // This will stop that event from happening
    if (reading) {
      console.log('ignoring reading')
      return
    }
    reading = true
    
    while (null !== (data = rr.read())) {
      // data variable will be an object with information from the line it read
      // PROCESS DATA HERE
      console.log('new line of data', data)
    }

    // All lines have been read and file is done.
    // End event will be called about now so that code will run before below code

    console.log('Finished readable')
  })


  rr.on("end", function () {
    // File has finished being read
    console.log('closing file')
  });

  rr.on("error", err => {
    // Some basic error handling for fs error events
    console.log('error', err);
  });
}

You will notice a reading flag. I have noticed that for some reason right near the end of the file the .on('readable') gets called a second time on small and large files. I am unsure why but this blocks that from a second process reading the same line items.

Necromancing.
It looks you have just as good a schema to work with as me... Here is how to do it correctly:

In this example, the table name is dbo.T_SYS_Language_Forms, and the column name is LANG_UID

-- First, chech if the table exists...
IF 0 < (
    SELECT COUNT(*) FROM INFORMATION_SCHEMA.TABLES 
    WHERE TABLE_TYPE = 'BASE TABLE'
    AND TABLE_SCHEMA = 'dbo'
    AND TABLE_NAME = 'T_SYS_Language_Forms'
)
BEGIN
    -- Check for NULL values in the primary-key column
    IF 0 = (SELECT COUNT(*) FROM T_SYS_Language_Forms WHERE LANG_UID IS NULL)
    BEGIN
        ALTER TABLE T_SYS_Language_Forms ALTER COLUMN LANG_UID uniqueidentifier NOT NULL 

        -- No, don't drop, FK references might already exist...
        -- Drop PK if exists 
        -- ALTER TABLE T_SYS_Language_Forms DROP CONSTRAINT pk_constraint_name 
        --DECLARE @pkDropCommand nvarchar(1000) 
        --SET @pkDropCommand = N'ALTER TABLE T_SYS_Language_Forms DROP CONSTRAINT ' + QUOTENAME((SELECT CONSTRAINT_NAME FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS 
        --WHERE CONSTRAINT_TYPE = 'PRIMARY KEY' 
        --AND TABLE_SCHEMA = 'dbo' 
        --AND TABLE_NAME = 'T_SYS_Language_Forms' 
        ----AND CONSTRAINT_NAME = 'PK_T_SYS_Language_Forms' 
        --))
        ---- PRINT @pkDropCommand 
        --EXECUTE(@pkDropCommand) 

        -- Instead do
        -- EXEC sp_rename 'dbo.T_SYS_Language_Forms.PK_T_SYS_Language_Forms1234565', 'PK_T_SYS_Language_Forms';


        -- Check if they keys are unique (it is very possible they might not be) 
        IF 1 >= (SELECT TOP 1 COUNT(*) AS cnt FROM T_SYS_Language_Forms GROUP BY LANG_UID ORDER BY cnt DESC)
        BEGIN

            -- If no Primary key for this table
            IF 0 =  
            (
                SELECT COUNT(*) FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS 
                WHERE CONSTRAINT_TYPE = 'PRIMARY KEY' 
                AND TABLE_SCHEMA = 'dbo' 
                AND TABLE_NAME = 'T_SYS_Language_Forms' 
                -- AND CONSTRAINT_NAME = 'PK_T_SYS_Language_Forms' 
            )
                ALTER TABLE T_SYS_Language_Forms ADD CONSTRAINT PK_T_SYS_Language_Forms PRIMARY KEY CLUSTERED (LANG_UID ASC)
            ;

            -- Adding foreign key
            IF 0 = (SELECT COUNT(*) FROM INFORMATION_SCHEMA.REFERENTIAL_CONSTRAINTS WHERE CONSTRAINT_NAME = 'FK_T_ZO_SYS_Language_Forms_T_SYS_Language_Forms') 
                ALTER TABLE T_ZO_SYS_Language_Forms WITH NOCHECK ADD CONSTRAINT FK_T_ZO_SYS_Language_Forms_T_SYS_Language_Forms FOREIGN KEY(ZOLANG_LANG_UID) REFERENCES T_SYS_Language_Forms(LANG_UID); 
        END -- End uniqueness check
        ELSE
            PRINT 'FSCK, this column has duplicate keys, and can thus not be changed to primary key...' 
    END -- End NULL check
    ELSE
        PRINT 'FSCK, need to figure out how to update NULL value(s)...' 
END 

CSharpJExcel for reading Excel 97-2003 files (XLS), ExcelPackage for reading Excel 2007/2010 files (Office Open XML format, XLSX), and ExcelDataReader that seems to have the ability to handle both formats

Good luck!

Generator expressions are also possible:

target_link_libraries(
    target_name
    PUBLIC
        libA
        $<$<PLATFORM_ID:Windows>:wsock32>
    PRIVATE
        $<$<PLATFORM_ID:Linux>:libB>
        libC
)

This will link libA, wsock32 & libC on Windows and link libA, libB & libC on Linux

Whatever Apple ships as the default gcc in xcode (4.2.1 on 10.6, 4.0.1 before) is well tested (and maintained) by the apple guys and the "standard" to build software with on OS X. Everything else is not, so think twice if you want to develop software, or be gcc/OS X beta tester.

Visual C 2010, and perhaps many other compilers, have direct support for boolean operations built in. A bit has two possible values, just like a boolean, so we can use booleans instead - even if they take up more space than a single bit in memory in this representation. This works, even the sizeof() operator works properly.

bool    IsGph[256], IsNotGph[256];

//  Initialize boolean array to detect printable characters
for(i=0; i<sizeof(IsGph); i++)  {
    IsGph[i] = isgraph((unsigned char)i);
}

So, to your question, IsGph[i] =1, or IsGph[i] =0 make setting and clearing bools easy.

To find unprintable characters:

//  Initialize boolean array to detect UN-printable characters, 
//  then call function to toggle required bits true, while initializing a 2nd
//  boolean array as the complement of the 1st.
for(i=0; i<sizeof(IsGph); i++)  {
    if(IsGph[i])    {
         IsNotGph[i] = 0;
    }   else   {
         IsNotGph[i] = 1;
    }
}

Note there is nothing "special" about this code. It treats a bit like an integer - which technically, it is. A 1 bit integer that can hold 2 values, and 2 values only.

I once used this approach to find duplicate loan records, where loan_number was the ISAM key, using the 6-digit loan number as an index into the bit array. Savagely fast, and after 8 months, proved that the mainframe system we were getting the data from was in fact malfunctioning. The simplicity of bit arrays makes confidence in their correctness very high - vs a searching approach for example.

You probably didn't fully deactivate the Conda environment - remember, the command you need to use with Conda is conda deactivate (for older versions, use source deactivate). So it may be wise to start a new shell and activate the environment in that before you try. Then deactivate it.

You can use the command

conda env remove -n ENV_NAME

to remove the environment with that name. (--name is equivalent to -n)

Note that you can also place environments anywhere you want using -p /path/to/env instead of -n ENV_NAME when both creating and deleting environments, if you choose. They don't have to live in your conda installation.

UPDATE, 30 Jan 2019: From Conda 4.6 onwards the conda activate command becomes the new official way to activate an environment across all platforms. The changes are described in this Anaconda blog post

Here is the solution which works for me:

I do the relative imports as from ..sub2 import mod2 and then, if I want to run mod1.py then I go to the parent directory of app and run the module using the python -m switch as python -m app.sub1.mod1.

The real reason why this problem occurs with relative imports, is that relative imports works by taking the __name__ property of the module. If the module is being directly run, then __name__ is set to __main__ and it doesn't contain any information about package structure. And, thats why python complains about the relative import in non-package error.

So, by using the -m switch you provide the package structure information to python, through which it can resolve the relative imports successfully.

I have encountered this problem many times while doing relative imports. And, after reading all the previous answers, I was still not able to figure out how to solve it, in a clean way, without needing to put boilerplate code in all files. (Though some of the comments were really helpful, thanks to @ncoghlan and @XiongChiamiov)

Hope this helps someone who is fighting with relative imports problem, because going through PEP is really not fun.

If you take a look at the MSIL as it's being executed you'll see that it doesn't compile down to the exact same code. When you use IsNothing() it actually makes a call to that method as opposed to just evaluating the expression.

The reason I would tend to lean towards using "Is Nothing" is when I'm negating it becomes "IsNot Nothing' rather than "Not IsNothing(object)" which I personally feel looks more readable.

I don't know if it is a solution but Invalidate Cache and Restart solved this problem in my case. I am currently using Android Studio 3.6

Modern answer: Use LocalDate from java.time, the modern Java date and time API, and its toString method:

    LocalDate date = LocalDate.of(2012, Month.DECEMBER, 1); // get from somewhere
    String formattedDate = date.toString();
    System.out.println(formattedDate);

This prints

2012-12-01

A date (whether we’re talking java.util.Date or java.time.LocalDate) doesn’t have a format in it. All it’s got is a toString method that produces some format, and you cannot change the toString method. Fortunately, LocalDate.toString produces exactly the format you asked for.

The Date class is long outdated, and the SimpleDateFormat class that you tried to use, is notoriously troublesome. I recommend you forget about those classes and use java.time instead. The modern API is so much nicer to work with.

Except: it happens that you get a Date from a legacy API that you cannot change or don’t want to change just now. The best thing you can do with it is convert it to java.time.Instant and do any further operations from there:

    Date oldfashoinedDate = // get from somewhere
    LocalDate date = oldfashoinedDate.toInstant()
            .atZone(ZoneId.of("Asia/Beirut"))
            .toLocalDate();

Please substitute your desired time zone if it didn’t happen to be Asia/Beirut. Then proceed as above.

Link: Oracle tutorial: Date Time, explaining how to use java.time.

With Git 2.23 onwards, one can use git switch <branch name> to switch branches.

This solves the issue in the appropriate way

// Merge a row
            ws.Cell("B2").Value = "Merged Row(1) of Range (B2:D3)";
            ws.Range("B2:D3").Row(1).Merge();

Another alternative way using get method with requests:

import requests
wjdata = requests.get('url').json()
print wjdata.get('data').get('current_condition')[0].get('temp_C')

I know this is an old thread but I got a nice solution to you (I think). It's copied from an class of mine, that handles all AJAX stuff.

When the script cannot be loaded, it set an error handler but when the error handler is not supported, it falls back to a timer that checks for errors for 15 seconds.

function jsLoader()
{
    var o = this;

    // simple unstopable repeat timer, when t=-1 means endless, when function f() returns true it can be stopped
    o.timer = function(t, i, d, f, fend, b)
    {
        if( t == -1 || t > 0 )
        {
            setTimeout(function() {
                b=(f()) ? 1 : 0;
                o.timer((b) ? 0 : (t>0) ? --t : t, i+((d) ? d : 0), d, f, fend,b );
            }, (b || i < 0) ? 0.1 : i);
        }
        else if(typeof fend == 'function')
        {
            setTimeout(fend, 1);
        }
    };

    o.addEvent = function(el, eventName, eventFunc)
    {

        }

        setTimeout( function() {
            var f = (typeof fCallback == 'function') ? fCallback : function(){};
            fErr = (typeof fErr == 'function') ? fErr : function(){
                alert('require: Cannot load resource -'+s);
            },
            fe = function(){

                    oo.id = 'failed';
                    fErr(oo);
                }
            };
            oo.onload = function() {
                oo.id = 'loaded';
                f(oo);
            };
            oo.type = 'text/javascript';

            oo.charset = 'utf-8';
            o.__es = false;
            o.addEvent( oo, 'error', fe ); // when supported

            // when error event is not supported fall back to timer
            o.timer(15, 1000, 0, function() {
                return (oo.id == 'loaded');
            }, function(){ 
                if(oo.id != 'loaded'){
                    fe();
                }
            });
            oo.src = s;
            setTimeout(function() {
                try{
                    oHead.appendChild(oo);
                }catch(e){
                    fe();
                }
            },1); 
        }, (typeof delay == 'number') ? delay : 1);  
        return true;
    };

}

$(document).ready( function()
{
    var ol = new jsLoader();
    ol.require('myscript.js', 800, true, function(){
        alert('loaded');
    }, function() {

    });
});

Simply make an object and extract arguments from that object.

let checkIfNumbersAddToTen = function (a, b) {
return new Promise(function (resolve, reject) {
 let c = parseInt(a)+parseInt(b);
 let promiseResolution = {
     c:c,
     d : c+c,
     x : 'RandomString'
 };
 if(c===10){
     resolve(promiseResolution);
 }else {
     reject('Not 10');
 }
});
};

Pull arguments from promiseResolution.

checkIfNumbersAddToTen(5,5).then(function (arguments) {
console.log('c:'+arguments.c);
console.log('d:'+arguments.d);
console.log('x:'+arguments.x);
},function (failure) {
console.log(failure);
});

I had a similar question, so I worked up a complete runnable answer below. What I needed to do is pass a class (C) to an object (O) of an unrelated class and have that object (O) emit new objects of class (C) back to me when I asked for them.

The example below shows how this is done. There is a MagicGun class that you load with any subtype of the Projectile class (Pebble, Bullet or NuclearMissle). The interesting is you load it with subtypes of Projectile, but not actual objects of that type. The MagicGun creates the actual object when it's time to shoot.

The Output

You've annoyed the target!
You've holed the target!
You've obliterated the target!
click
click

The Code

import java.util.ArrayList;
import java.util.List;

public class PassAClass {
    public static void main(String[] args) {
        MagicGun gun = new MagicGun();
        gun.loadWith(Pebble.class);
        gun.loadWith(Bullet.class);
        gun.loadWith(NuclearMissle.class);
        //gun.loadWith(Object.class);   // Won't compile -- Object is not a Projectile
        for(int i=0; i<5; i++){
            try {
                String effect = gun.shoot().effectOnTarget();
                System.out.printf("You've %s the target!\n", effect);
            } catch (GunIsEmptyException e) {
                System.err.printf("click\n");
            }
        }
    }

6 years late to the party but I've been searching for how to extract an html element's tag attribute value, so for:

<span property="addressLocality">Ayr</span>

I want "addressLocality". I kept being directed back here, but the answers didn't really solve my problem.

How I managed to do it eventually:

>>> from bs4 import BeautifulSoup as bs

>>> soup = bs('<span property="addressLocality">Ayr</span>', 'html.parser')
>>> my_attributes = soup.find().attrs
>>> my_attributes
{u'property': u'addressLocality'}

As it's a dict, you can then also use keys and 'values'

>>> my_attributes.keys()
[u'property']
>>> my_attributes.values()
[u'addressLocality']

Hopefully it helps someone else!

try this

$(document).on("submit", "#form-data", function(e){
    e.preventDefault()
    $.ajax({
        url: "edit.php",
        method: "POST",
        data: new FormData(this),
        contentType: false,
        processData: false,
        success: function(data){
            $('.center').html(data); 
        }
    })
})

in the form the button needs to be type="submit"

$date = mysql_real_escape_string($_POST['intake_date']);

1. If your MySQL column is DATE type:

$date = date('Y-m-d', strtotime(str_replace('-', '/', $date)));

2. If your MySQL column is DATETIME type:

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

You haven't got to work strototime(), because it will not work with dash - separators, it will try to do a subtraction.

Update, the way your date is formatted you can't use strtotime(), use this code instead:

$date = '02/07/2009 00:07:00';
$date = preg_replace('#(\d{2})/(\d{2})/(\d{4})\s(.*)#', '$3-$2-$1 $4', $date);
echo $date;

Output:

2009-07-02 00:07:00

There are multiple ways to achieve this. I can explain you in brief about the 4 types which we use in our daily programming life cycle.

Please go through the below points.

1 Query String.

FirstForm.aspx.cs

Response.Redirect("SecondForm.aspx?Parameter=" + TextBox1.Text);

SecondForm.aspx.cs

TextBox1.Text = Request.QueryString["Parameter"].ToString();

This is the most reliable way when you are passing integer kind of value or other short parameters. More advance in this method if you are using any special characters in the value while passing it through query string, you must encode the value before passing it to next page. So our code snippet of will be something like this:

FirstForm.aspx.cs

Response.Redirect("SecondForm.aspx?Parameter=" + Server.UrlEncode(TextBox1.Text));

SecondForm.aspx.cs

TextBox1.Text = Server.UrlDecode(Request.QueryString["Parameter"].ToString());

URL Encoding

1. Server.URLEncode
   
2. HttpServerUtility.UrlDecode

2. Passing value through context object

Passing value through context object is another widely used method.

FirstForm.aspx.cs

TextBox1.Text = this.Context.Items["Parameter"].ToString();

SecondForm.aspx.cs

this.Context.Items["Parameter"] = TextBox1.Text;
Server.Transfer("SecondForm.aspx", true);

Note that we are navigating to another page using Server.Transfer instead of Response.Redirect.Some of us also use Session object to pass values. In that method, value is store in Session object and then later pulled out from Session object in Second page.

3. Posting form to another page instead of PostBack

Third method of passing value by posting page to another form. Here is the example of that:

FirstForm.aspx.cs

private void Page_Load(object sender, System.EventArgs e)
{
   buttonSubmit.Attributes.Add("onclick", "return PostPage();");
}

And we create a javascript function to post the form.

SecondForm.aspx.cs

function PostPage()
{
   document.Form1.action = "SecondForm.aspx";
   document.Form1.method = "POST";
   document.Form1.submit();
}
TextBox1.Text = Request.Form["TextBox1"].ToString();

Here we are posting the form to another page instead of itself. You might get viewstate invalid or error in second page using this method. To handle this error is to put EnableViewStateMac=false

4. Another method is by adding PostBackURL property of control for cross page post back

In ASP.NET 2.0, Microsoft has solved this problem by adding PostBackURL property of control for cross page post back. Implementation is a matter of setting one property of control and you are done.

FirstForm.aspx.cs

<asp:Button id=buttonPassValue style=”Z-INDEX: 102" runat=”server” Text=”Button”         PostBackUrl=”~/SecondForm.aspx”></asp:Button>

SecondForm.aspx.cs

TextBox1.Text = Request.Form["TextBox1"].ToString();

In above example, we are assigning PostBackUrl property of the button we can determine the page to which it will post instead of itself. In next page, we can access all controls of the previous page using Request object.

You can also use PreviousPage class to access controls of previous page instead of using classic Request object.

SecondForm.aspx

TextBox textBoxTemp = (TextBox) PreviousPage.FindControl(“TextBox1");
TextBox1.Text = textBoxTemp.Text;

As you have noticed, this is also a simple and clean implementation of passing value between pages.

Why not to use Static Initialization Blocks ? Additional details here: Static Initialization Blocks

Try this

User.where("id > ?", 200) 

After uncommenting disable_overscan=1 follow my lead. In the link, http://elinux.org/RPiconfig when you search for Video options, you'll also get hdmi_group and hdmi_mode. For, hdmi_group choose 1 if you're using you TV as an video output or choose 2 for monitors. Then in hdmi_mode, you can select the resolution you want from the list. I chose :- hdmi_group=2 hdmi_mode=23 And it worked.

Just add both these files after opening of body tag. Keep in mind 'Only after Body tag' any where after body tag. If you add below mentioned files inside body tag then your problems would still be unresolved.

So paste them after or before close of body tag... This works 100%. I've tested and got it working!

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
 <!-- Include all compiled plugins (below), or include individual files as needed -->
<script src="js/bootstrap.min.js"></script>

Decorate the model property with the DisplayName attribute.

var iframe = document.getElementById('youriframe');
iframe.src = iframe.src;

To disable inputting password:

sudo visudo

Then add a new line like below and save then:

# The user can run installer as root without inputting password
yourusername ALL=(root) NOPASSWD: /usr/sbin/installer

Then you run installer without password:

sudo installer -pkg ...

There is a visual studio extension Automatic Versions which supports Visual Studio (2012, 2013, 2015) 2017 & 2019.

Screen Shots

The USAGE-privilege in mysql simply means that there are no privileges for the user 'phpadmin'@'localhost' defined on global level *.*. Additionally the same user has ALL-privilege on database phpmyadmin phpadmin.*.

So if you want to remove all the privileges and start totally from scratch do the following:

• Revoke all privileges on database level:

  REVOKE ALL PRIVILEGES ON phpmyadmin.* FROM 'phpmyadmin'@'localhost';

• Drop the user 'phpmyadmin'@'localhost'

  DROP USER 'phpmyadmin'@'localhost';

Above procedure will entirely remove the user from your instance, this means you can recreate him from scratch.

To give you a bit background on what described above: as soon as you create a user the mysql.user table will be populated. If you look on a record in it, you will see the user and all privileges set to 'N'. If you do a show grants for 'phpmyadmin'@'localhost'; you will see, the allready familliar, output above. Simply translated to "no privileges on global level for the user". Now your grant ALL to this user on database level, this will be stored in the table mysql.db. If you do a SELECT * FROM mysql.db WHERE db = 'nameofdb'; you will see a 'Y' on every priv.

Above described shows the scenario you have on your db at the present. So having a user that only has USAGE privilege means, that this user can connect, but besides of SHOW GLOBAL VARIABLES; SHOW GLOBAL STATUS; he has no other privileges.

You can do it on a per file basis. Use the path attribute to include the filename

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <location path="YourFileNameHere.xml">
        <system.webServer>
            <staticContent>
                <clientCache cacheControlMode="DisableCache" />
            </staticContent>
        </system.webServer>
    </location>
</configuration>

You could try using FontAwesome. It contains a sort-icon (http://fontawesome.io/icon/sort/).

To do so, you would

1. need to include fontawesome:

   <link href="//maxcdn.bootstrapcdn.com/font-awesome/4.1.0/css/font-awesome.min.css" rel="stylesheet">
   

2. and then simply use the fontawesome-icon instead of the default-bootstrap-icons in your th's:

   <th><b>#</b> <i class="fa fa-fw fa-sort"></i></th>
   

Hope that helps.

I realize this is a little old, but, yes it can be done. Some javascript to get you started:

viewport = document.querySelector("meta[name=viewport]");
viewport.setAttribute('content', 'width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0');

Just change the parts you need and Mobile Safari will respect the new settings.

Update:

If you don't already have the meta viewport tag in the source, you can append it directly with something like this:

var metaTag=document.createElement('meta');
metaTag.name = "viewport"
metaTag.content = "width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0"
document.getElementsByTagName('head')[0].appendChild(metaTag);

Or if you're using jQuery:

$('head').append('<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0">');

Your code is working at my end, i have just tested it. Where are you checking your changes? Use Documents directory path. To get path -

NSLog(@"%@",documentsDirectory);

and copy path from console and then open finder and press Cmd+shift+g and paste path here and then open your file

ADO.NET 2.0 Provider for SQLite has over 200 downloads every day, so I think you are safe using that one.

You have to do two things before a submodule will be filled:

git submodule init 
git submodule update

        id: id,
        name: name,
        adr: adr,
        city: city,
        state: state,
        zip: zip

    }
}

objFacility('wlevine', 'Levine', '23 Skid Row', 'Springfield', 'Il', 10010);

"The object can be obtained with"

objFacility.wlevine

The objects properties are now accessable from within any other function.

A small word of caution, if "do some stuff" means updating the value of the actual property that you visit AND if there is a struct type property along the path from root object to the visited property, the change you made on the property will not be reflected on the root object.

There are basically 3 alternatives to cleaning everything that you could try:

• flutter clean will delete the /build folder.
• Manually delete the /build folder, which is essentially the same as flutter clean.
• Or, as @Rémi Roudsselet pointed out: restart your IDE, as it might be caching some older error logs and locking everything up.

Try: sed -n '$=' filename

Also cat is unnecessary: wc -l filename is enough in your present way.

sudo apt-get install nodejs

installs nodejs

sudo apt-get install npm

installs npm

sudo npm install bower -g

installs bower via npm

Better approach may be a polyfill like this

jQuery.fn.load = function(callback){ $(window).on("load", callback) };

With this you can leave the legacy code untouched. If you use webpack be sure to use script-loader.

Just use the crossOrigin attribute and pass 'anonymous' as the second parameter

var img = new Image();
img.setAttribute('crossOrigin', 'anonymous');
img.src = url;

That method was introduced in Commons Codec 1.4. This exception indicates that you've an older version of Commons Codec somewhere else in the webapp's runtime classpath which got precedence in classloading. Check all paths covered by the webapp's runtime classpath. This includes among others the Webapp/WEB-INF/lib, YourAppServer/lib, JRE/lib and JRE/lib/ext. Finally remove or upgrade the offending older version.

Update: as per the comments, you can't seem to locate it. I can only suggest to outcomment the code using that newer method and then put the following line in place:

System.out.println(Base64.class.getProtectionDomain().getCodeSource().getLocation());

That should print the absolute path to the JAR file where it was been loaded from during runtime.

Update 2: this did seem to point to the right file. Sorry, I can't explain your problem anymore right now. All I can suggest is to use a different Base64 method like encodeBase64(byte[]) and then just construct a new String(bytes) yourself. Or you could drop that library and use a different Base64 encoder, for example this one.

Another thing to check is if any applications still have a hold on the file.

Had some issues with MoveFile. Part of my permissions problem was that my script opens the file (in this case in Excel), makes a modification, closes it, then moves it to a "processed" folder.

In debugging a couple things, the script crashed a few times. Digging into the permission denied error I found that I had 4 instances of Excel running in the background because the script was never able to properly terminate the application due to said crashes. Apparently one of them still had a hold on the file and, thusly, "permission denied."

You can use tool I've created to make this process easier: git-squash. For example to squash all commits on feature branch that has been branched from master branch, write:

git squash master
git push --force

Nobody seems to be explaining the difference between an array and an object.

[] is declaring an array.

{} is declaring an object.

An array has all the features of an object with additional features (you can think of an array like a sub-class of an object) where additional methods and capabilities are added in the Array sub-class. In fact, typeof [] === "object" to further show you that an array is an object.

The additional features consist of a magic .length property that keeps track of the number of items in the array and a whole slew of methods for operating on the array such as .push(), .pop(), .slice(), .splice(), etc... You can see a list of array methods here.

An object gives you the ability to associate a property name with a value as in:

var x = {};
x.foo = 3;
x["whatever"] = 10;
console.log(x.foo);      // shows 3
console.log(x.whatever); // shows 10

Object properties can be accessed either via the x.foo syntax or via the array-like syntax x["foo"]. The advantage of the latter syntax is that you can use a variable as the property name like x[myvar] and using the latter syntax, you can use property names that contain characters that Javascript won't allow in the x.foo syntax.

A property name can be any string value.

An array is an object so it has all the same capabilities of an object plus a bunch of additional features for managing an ordered, sequential list of numbered indexes starting from 0 and going up to some length. Arrays are typically used for an ordered list of items that are accessed by numerical index. And, because the array is ordered, there are lots of useful features to manage the order of the list .sort() or to add or remove things from the list.

If you only want to add Datapoints above the bars, you could easily do it with:

 for i in range(len(frequencies)): # your number of bars
    plt.text(x = x_values[i]-0.25, #takes your x values as horizontal positioning argument 
    y = y_values[i]+1, #takes your y values as vertical positioning argument 
    s = data_labels[i], # the labels you want to add to the data
    size = 9) # font size of datalabels

Ok for the adapter FragmentStatePagerAdapter I fund a solution :

in your FragmentActivity :

ActionBar mActionBar = getSupportActionBar(); 
mActionBar.addTab(mActionBar.newTab().setText("TAB1").setTabListener(this).setTag(Fragment.instantiate(this, MyFragment1.class.getName())));
mActionBar.addTab(mActionBar.newTab().setText("TAB2").setTabListener(this).setTag(Fragment.instantiate(this, MyFragment2.class.getName())));
mActionBar.addTab(mActionBar.newTab().setText("TAB3").setTabListener(this).setTag(Fragment.instantiate(this, MyFragment3.class.getName())));

viewPager = (STViewPager) super.findViewById(R.id.viewpager);
mPagerAdapter = new MyPagerAdapter(getSupportFragmentManager(), mActionBar);
viewPager.setAdapter(this.mPagerAdapter);

and create a methode in your class FragmentActivity - So that method give you access to your Fragment, you just need to give it the position of the fragment you want:

public Fragment getActiveFragment(int position) {
String name = MyPagerAdapter.makeFragmentName(position);
return getSupportFragmentManager().findFragmentByTag(name);
}

in your Adapter :

public class MyPagerAdapter extends FragmentStatePagerAdapter {

private final ActionBar actionBar;
private final FragmentManager fragmentManager;

public MyPagerAdapter(FragmentManager fragmentManager, com.actionbarsherlock.app.ActionBarActionBar mActionBar) {super(fragmentManager);
this.actionBar = mActionBar;
this.fragmentManager = fragmentManager;
}

@Override
public Fragment getItem(int position) {
getSupportFragmentManager().beginTransaction().add(mTchatDetailsFragment, makeFragmentName(position)).commit();
return (Fragment)this.actionBar.getTabAt(position);
}

@Override
public int getCount() {
return this.actionBar.getTabCount();
}

@Override
public CharSequence getPageTitle(int position) {
return this.actionBar.getTabAt(position).getText();
}

private static String makeFragmentName(int viewId, int index) {
return "android:fragment:" + index;
}

}

You would need to use a reinterpret_cast<> as the two types you are casting between are unrelated to each other.

Get All Parent Iframe functions and HTML

var parent = $(window.frameElement).parent();
        //alert(parent+"TESTING");
        var parentElement=window.frameElement.parentElement.parentElement.parentElement.parentElement;
        var Ifram=parentElement.children;      
        var GetUframClass=Ifram[9].ownerDocument.activeElement.className;
        var Decision_URLLl=parentElement.ownerDocument.activeElement.contentDocument.URL;

If your app is meant to run on the device, make sure you are not trying to run in it on the simulator. May sound obvious, but check anyway.

See:

• JLS 8.7, Static Initializers
• JLS 12.2, Loading of Classes and Interfaces
• JLS 12.4, Initialization of Classes and Interfaces

The last in particular provides detailed initialization steps that spell out when static variables are initialized, and in what order (with the caveat that final class variables and interface fields that are compile-time constants are initialized first.)

I'm not sure what your specific question about point 3 (assuming you mean the nested one?) is. The detailed sequence states this would be a recursive initialization request so it will continue initialization.

Simple class to calculate rolling average and also rolling standard deviation:

#define _stdev(cnt, sum, ssq) sqrt((((double)(cnt))*ssq-pow((double)(sum),2)) / ((double)(cnt)*((double)(cnt)-1)))

class moving_average {
private:
    boost::circular_buffer<int> *q;
    double sum;
    double ssq;
public:
    moving_average(int n)  {
        sum=0;
        ssq=0;
        q = new boost::circular_buffer<int>(n);
    }
    ~moving_average() {
        delete q;
    }
    void push(double v) {
        if (q->size() == q->capacity()) {
            double t=q->front();
            sum-=t;
            ssq-=t*t;
            q->pop_front();
        }
        q->push_back(v);
        sum+=v;
        ssq+=v*v;
    }
    double size() {
        return q->size();
    }
    double mean() {
        return sum/size();
    }
    double stdev() {
        return _stdev(size(), sum, ssq);
    }

};

For ndarray there is a numpy method called unique:

np.unique(array_name)

Examples:

>>> np.unique([1, 1, 2, 2, 3, 3])
array([1, 2, 3])
>>> a = np.array([[1, 1], [2, 3]])
>>> np.unique(a)
array([1, 2, 3])

For a Series there is a function call value_counts():

Series_name.value_counts()

Just needs to go:

Solution Explorer-->Go to Properties --->change(Single Startup project) from.dll to .web

Then try to debug it.

Surely your problem will be solved.

I would be very careful with self closing tags as this example demonstrates:

var a = '<span/><span/>';
var d = document.createElement('div');
d.innerHTML = a
console.log(d.innerHTML) // "<span><span></span></span>"

My gut feeling would have been <span></span><span></span> instead

Please change your code as follows:

<script>
    var button = document.getElementById("reactionTester");
    var start = document.getElementById("start");
    function init() {
        var startInterval/*in milliseconds*/ = Math.floor(Math.random()*30)*1000;
        setTimeout(startTimer,startInterval); 
    }
    function startTimer(){
        document.write("hey");
    }
</script>

See if that helps. Basically, the difference is references the 'startTimer' function instead of executing it.

You can use a JSON as well to store and send JS functions.

Check the following:

var myJSON = 
{
    "myFunc1" : function (){
        alert("a");
    }, 
    "myFunc2" : function (functionParameter){
        functionParameter();
    }
}



function main(){
    myJSON.myFunc2(myJSON.myFunc1);
}

This will print 'a'.

The following has the same effect with the above:

var myFunc1 = function (){
    alert('a');
}

var myFunc2 = function (functionParameter){
    functionParameter();
}

function main(){
    myFunc2(myFunc1);
}

Which is also has the same effect with the following:

function myFunc1(){
    alert('a');
}


function myFunc2 (functionParameter){
    functionParameter();
}

function main(){
    myFunc2(myFunc1);
}

And a object paradigm using Class as object prototype:

function Class(){
    this.myFunc1 =  function(msg){
        alert(msg);
    }

    this.myFunc2 = function(callBackParameter){
        callBackParameter('message');
    }
}


function main(){    
    var myClass = new Class();  
    myClass.myFunc2(myClass.myFunc1);
}

On bootstrap-modal.js v2.2.0:

( $('element').data('modal') || {}).isShown

You're correct that this is really painful to hand out to others, but if you have to, this is how you do it.

1. Just extract the .ocx file from the .cab file (it is similar to a zip)
2. Copy to the system folder (c:\windows\sysWOW64 for 64 bit systems and c:\windows\system32 for 32 bit)
3. Use regsvr32 through the command prompt to register the file (e.g. "regsvr32 c:\windows\sysWOW64\mscomct2.ocx")

If you are experiencing errors during PKG installation following the accepted answer, I will give you another procedure that worked for me (please note the little changes to xar, cpio and mkbom commands):

mkdir Foo
cd Foo
xar -xf ../Foo.pkg
cd foo.pkg
cat Payload | gunzip -dc | cpio -i
# edit Foo.app/*
rm Payload
find ./Foo.app | cpio -o --format odc --owner 0:80 | gzip -c > Payload
mkbom -u 0 -g 80 Foo.app Bom # or edit Bom
# edit PackageInfo
rm -rf Foo.app
cd ..
xar --compression none -cf ../Foo-new.pkg

The resulted PKG will have no compression, cpio now uses odc format and specify the owner of the file as well as mkbom.

Using private API:

@objc func tableViewDidFinishReload(_ tableView: UITableView) {
    print(#function)
    cellsAreLoaded = true
}

Using public API:

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    // cancel the perform request if there is another section
    [NSObject cancelPreviousPerformRequestsWithTarget:self selector:@selector(tableViewDidLoadRows:) object:tableView];

    // create a perform request to call the didLoadRows method on the next event loop.
    [self performSelector:@selector(tableViewDidLoadRows:) withObject:tableView afterDelay:0];

    return [self.myDataSource numberOfRowsInSection:section];
}

// called after the rows in the last section is loaded
-(void)tableViewDidLoadRows:(UITableView*)tableView{
    self.cellsAreLoaded = YES;
}

A possible better design is to add the visible cells to a set, then when you need to check if the table is loaded you can instead do a for loop around this set, e.g.

var visibleCells = Set<UITableViewCell>()

override func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) {
    visibleCells.insert(cell)
}

override func tableView(_ tableView: UITableView, didEndDisplaying cell: UITableViewCell, forRowAt indexPath: IndexPath) {
    visibleCells.remove(cell)
}

// example property you want to show on a cell that you only want to update the cell after the table is loaded. cellForRow also calls configure too for the initial state.
var count = 5 {
    didSet {
        for cell in visibleCells {
            configureCell(cell)
        }
    }
}

If you're looking to do something with a list of files, you can use find combined with the bash $() construct (better than backticks since it's allowed to nest).

for example, say you're at the top level of your project directory and you want a list of all C files starting with "btree". The command:

find . -type f -name 'btree*.c'

will return a list of them. But this doesn't really help with doing something with them.

So, let's further assume you want to search all those file for the string "ERROR" or edit them all. You can execute one of:

grep ERROR $(find . -type f -name 'btree*.c')
vi $(find . -type f -name 'btree*.c')

to do this.

preg_match needs a / or another char as delimiter.

preg_match("/^[0-9]{4}-[0-1][0-9]-[0-3][0-9]$/",$date)

you also should check for validity of that date so you wouldn't end up with something like 9999-19-38

bool checkdate ( int $month , int $day , int $year )

you can find default port configuration at start your app

yourapp/scripts/start.js

scroll down and change the port to whatever you want

const DEFAULT_PORT = parseInt(process.env.PORT, 10) || 4000;

hope this may help you ;)

If you want to convert all *.ipynb files from current directory to python script, you can run the command like this:

jupyter nbconvert --to script *.ipynb

Morgan :- Morgan is a middleware which will help us to identify the clients who are accessing our application. Basically a logger.

To Use Morgan, We need to follow below steps :-

1. Install the morgan using below command:

npm install --save morgan

This will add morgan to json.package file

2. Include the morgan in your project

var morgan = require('morgan');

3> // create a write stream (in append mode)

var accessLogStream = fs.createWriteStream(
      path.join(__dirname, 'access.log'), {flags: 'a'}
 );
// setup the logger 
app.use(morgan('combined', {stream: accessLogStream}));

Note: Make sure you do not plumb above blindly make sure you have every conditions where you need .

Above will automatically create a access.log file to your root once user will access your app.

This worked for me:

string Connection = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source="
    + HttpContext.Current.Server.MapPath("\\myPath\\myFile.db")
    + ";Extended Properties=\"Excel 12.0 Xml;HDR=YES\"";

I'm querying an XLSX file so don't worry about any of the other stuff in the connection string but the Data Source.

So my answer is:

HttpContext.Current.Server.MapPath("\\myPath\\myFile.db")

you can try this function , very basic

public String getWithoutExtension(String fileFullPath){
    return fileFullPath.substring(0, fileFullPath.lastIndexOf('.'));
}

String path = "Your_Path";
File f = new File(path);

if (f.isDirectory()){



  }else if(f.isFile()){



  }

This way you have more control over the output - i.e - if you wanted the time format to be '4:30 pm' instead of '04:30 P.M.' - you can convert to whatever format you decide you want - and change it later too. Instead of being constrained to some old method that does not allow any flexibility.

and you only need to convert the first 2 digits as the minute and seconds digits are the same in 24 hour time or 12 hour time.

var my_time_conversion_arr = {'01':"01", '02':"02", '03':"03", '04':"04", '05':"05", '06':"06", '07':"07", '08':"08", '09':"09", '10':"10", '11':"11", '12': "12", '13': "1", '14': "2", '15': "3", '16': "4", '17': "5", '18': "6", '19': "7", '20': "8", '21': "9", '22': "10", '23': "11", '00':"12"};

                var AM_or_PM = "";
                var twenty_four_hour_time = "16:30";
                var twenty_four_hour_time_arr = twenty_four_hour_time.split(":");
                var twenty_four_hour_time_first_two_digits = twenty_four_hour_time_arr[0];

                var first_two_twelve_hour_digits_converted = my_time_conversion_arr[twenty_four_hour_time_first_two_digits];

                var time_strng_to_nmbr = parseInt(twenty_four_hour_time_first_two_digits);
                if(time_strng_to_nmbr >12){
                    //alert("GREATER THAN 12");
                    AM_or_PM = "pm";
                }else{
                    AM_or_PM = "am";
                }

                var twelve_hour_time_conversion = first_two_twelve_hour_digits_converted+":"+twenty_four_hour_time_arr[1]+" "+AM_or_PM;

location ~ [^/]\.php(/|$) {
         fastcgi_pass unix:/PATH_TO_YOUR_PHPFPM_SOCKET_FILE/php7.0-fpm.sock;
         include fastcgi_params;
         fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

Good luck

/usr/sbin/ifconfig -a | awk 'BEGIN { count=0; } { if ( $1 ~ /inet/ ) { count++; if( count==2 ) { print $2; } } }'

This will list down the exact ip address for the machine

Here's another way of getting a Bash array with the example JSON given by @anubhava in his answer:

arr=($(jq --raw-output 'keys_unsorted | @sh' file.json))

echo ${arr[0]}    # 'Archiver-Version'
echo ${arr[1]}    # 'Build-Id'
echo ${arr[2]}    # 'Build-Jdk'

Loose coupling means that the degree of dependency between two components is very low.
Example: GSM SIM

Tight coupling means that the degree of dependency between two components is very high.
Example: CDMA Mobile

You've already done it correctly by using a DateTime parameter with the value from the DateTime, so it should already work. Forget about ToString() - since that isn't used here.

If there is a difference, it is most likely to do with different precision between the two environments; maybe choose a rounding (seconds, maybe?) and use that. Also keep in mind UTC/local/unknown (the DB has no concept of the "kind" of date; .NET does).

I have a table and the date-times in it are in the format: 2011-07-01 15:17:33.357

Note that datetimes in the database aren't in any such format; that is just your query-client showing you white lies. It is stored as a number (and even that is an implementation detail), because humans have this odd tendency not to realise that the date you've shown is the same as 40723.6371916281. Stupid humans. By treating it simply as a "datetime" throughout, you shouldn't get any problems.

You need to download their source from the github. Find the main file and then include it in your main file.

An example of this can be found here > How to manually install a node.js module?

Usually you need to find the source and go through the package.json file. There you can find which is the main file. So that you can include that in your application.

To include example.js in your app. Copy it in your application folder and append this on the top of your main js file.

var moduleName = require("path/to/example.js")

I'd just like to add a correction here for the future readers of this thread. This particular nuance has escaped my understanding for a long time so I want to make sure none of you make the same mistakes:

System.exit() does not kill your app if you have more than one activity on the stack. What actually happens is that the process is killed and immediately restarted with one fewer activity on the stack. This is also what happens when your app is killed by the Force Close dialog, or even when you try to kill the process from DDMS. This is a fact that is entirely undocumented, to my knowledge.

The short answer is, if you want to exit your application, you've got to keep track of all activities in your stack and finish() ALL of them when the user wants to exit (and no, there is no way to iterate through the Activity stack, so you have to manage all of this yourself). Even this does not actually kill the process or any dangling references you may have. It simply finishes the activities. Also, I'm not sure whether Process.killProcess(Process.myPid()) works any better; I haven't tested it.

If, on the other hand, it is okay for you to have activities remaining in your stack, there is another method which makes things super easy for you: Activity.moveTaskToBack(true) will simply background your process and show the home screen.

The long answer involves explanation of the philosophy behind this behavior. The philosophy is born out of a number of assumptions:

1. First of all, this only happens when your app is in the foreground. If it is in the background the process will terminate just fine. However, if it is in the foreground, the OS assumes that the user wants to keep doing whatever he/she was doing. (If you are trying to kill the process from DDMS, you should hit the home button first, and then kill it)
2. It also assumes that each activity is independent of all the other activities. This is often true, for example in the case that your app launches the Browser Activity, which is entirely separate and was not written by you. The Browser Activity may or may not be created on the same Task, depending on its manifest attributes.
3. It assumes that each of your activities is completely self-reliant and can be killed/restored in a moment's notice. (I rather dislike this particular assumption, since my app has many activities which rely on a large amount of cached data, too large to be efficiently serialized during onSaveInstanceState, but whaddya gonna do?) For most well-written Android apps this should be true, since you never know when your app is going to be killed off in the background.
4. The final factor is not so much an assumption, but rather a limitation of the OS: killing the app explicitly is the same as the app crashing, and also the same as Android killing the app to reclaim memory. This culminates in our coup de grace: since Android can't tell if the app exited or crashed or was killed in the background, it assumes the user wants to return where they left off, and so the ActivityManager restarts the process.

When you think about it, this is appropriate for the platform. First, this is exactly what happens when the process is killed in the background and the user comes back to it, so it needs to be restarted where it left off. Second, this is what happens when the app crashes and presents the dreaded Force Close dialog.

Say I want my users to be able to take a picture and upload it. I launch the Camera Activity from my activity, and ask it to return an image. The Camera is pushed onto the top of my current Task (rather than being created in its own Task). If the Camera has an error and it crashes, should that result in the whole app crashing? From the standpoint of the user, only the Camera failed, and they should be returned to their previous activity. So it just restarts the process with all the same Activities in the stack, minus the Camera. Since your Activities should be designed so that they can be killed and restored at the drop of a hat, this shouldn't be a problem. Unfortunately, not all apps can be designed that way, so it is a problem for many of us, no matter what Romain Guy or anyone else tells you. So, we need to use workarounds.

So, my closing advice:

• Don't try to kill the process. Either call finish() on all activities or call moveTaskToBack(true).
• If your process crashes or gets killed, and if, like me, you need the data that was in memory which is now lost, you'll need to return to the root activity. To do this, you should call startActivity() with an Intent that contains the Intent.FLAG_ACTIVITY_CLEAR_TOP flag.
• If you want to kill your app from the Eclipse DDMS perspective, it had better not be in the foreground, or it will restart itself. You should press the Home button first, and then kill the process.

setting up a special stack frame for the try/catch adds additional overhead, but the JVM may be able to detect the fact that you're returning and optimize this away.

depending on the number of iterations, performance difference will likely be negligible.

However i agree with the others that having it outside the loop make the loop body look cleaner.

If there's a chance that you'll ever want to continue on with the processing rather than exit if there an invalid number, then you would want the code to be inside the loop.

just a note: CPLUS_INCLUDE_PATH and C_INCLUDE_PATH are not the equivalent of LD_LIBRARY_PATH. LD_LIBRARY_PATH serves the ld (the dynamic linker at runtime) whereas the equivalent of the former two that serves your C/C++ compiler with the location of libraries is LIBRARY_PATH.

I had same error and I change the setting from release to debug and the problem resolved..

A bit clunky, but this works for me right now to set background and text colors. I found it here.

UIView * firstView = alertController.view.subviews.firstObject;
    UIView * nextView = firstView.subviews.firstObject;
    nextView.backgroundColor = [UIColor blackColor];

MobileESP has PHP, Java, APS.NET (C#), Ruby and JavaScript hooks. it has also the Apache 2 licence, so free for commercial use. Key thing for me is it only identifies browsers and platforms not screen sizes and other metrics, which keeps it nice an small.

I usually use

DATE_ADD(CURDATE(), INTERVAL - 1 MONTH)

Which is almost same as Pekka's but this way you can control your INTERVAL to be negative or positive...

Another idea is to do myVar.split(',')[1];

For simple case, not using a regexp is a good idea...

I think you need to put your $page = 'one'; above the require_once.. otherwise I don't understand the question.

I don't know about MySQL, but in MS SQL, you can use the column index in the order by clause. I've done this before when doing counts with group bys as it tends to be easier to work with.

So

SELECT COUNT(id), `Tag` from `images-tags`
GROUP BY `Tag`
ORDER BY COUNT(id) DESC
LIMIT 20

Becomes

SELECT COUNT(id), `Tag` from `images-tags`
GROUP BY `Tag`
ORDER 1 DESC
LIMIT 20

The best sorting technique of all generally depends upon the size of an array. Merge sort can be the best of all as it manages better space and time complexity according to the Big-O algorithm (This suits better for a large array).

you can keep booth EAGER lists in JPA and add to at least one of them the JPA annotation @OrderColumn (with obviously the name of a field to be ordered). No need of specific hibernate annotations. But keep in mind it could create empty elements in the list if the chosen field does not have values starting from 0

 [...]
 @OneToMany(mappedBy="parent", fetch=FetchType.EAGER)
 @OrderColumn(name="orderIndex")
 private List<Child> children;
 [...]

in Children then you should add the orderIndex field

Here is a simple construct that will do it, by using setdiff:

rm(list=setdiff(ls(), "x"))

And a full example. Run this at your own risk - it will remove all variables except x:

x <- 1
y <- 2
z <- 3
ls()
[1] "x" "y" "z"

rm(list=setdiff(ls(), "x"))

ls()
[1] "x"

Math.random no, but the ran library solves this. It has almost all distributions you can imagine and supports seeded random number generation. Example:

ran.core.seed(0)
myDist = new ran.Dist.Uniform(0, 1)
samples = myDist.sample(1000)

You can use the ncp module. I think this is what you need.

In case if someone is using Gradle for the build then fix will be by adding the following lines in build.gradle file

apply plugin: 'application'

mainClassName = "com.example.demo.DemoApplication"
