Looks like whatever is in your Animation Drawable definition is too much memory to decode and sequence. The idea is that it loads up all the items and make them in an array and swaps them in and out of the scene according to the timing specified for each frame.

If this all can't fit into memory, it's probably better to either do this on your own with some sort of handler or better yet just encode a movie with the specified frames at the corresponding images and play the animation through a video codec.

I had the same problem. If you try to upload an image that is too large on some low resolution devices, the app will collapse. You can make several images of different sizes (hdpi, xxdpi and more) or simply use an external library to load images that solve the problem quickly and efficiently. I used Glide library (you can use another library like Picasso).

    panel_IMG_back = (ImageView) findViewById(R.id.panel_IMG_back);
    Glide
            .with(this)
            .load(MyViewUtils.getImage(R.drawable.wallpaper)
            .into(panel_IMG_back);

Remove below lines from style or style(21)

<item name="android:windowDrawsSystemBarBackgrounds">true</item>
<item name="android:statusBarColor">@color/colorPrimaryDark</item>
<item name="android:windowTranslucentStatus">false</item>

android.widget.Button.setOnClickListener(android.view.View$OnClickListener)' on a null object reference

Because Submit button is inside login_modal so you need to use loginDialog view to access button:

Submit = (Button)loginDialog.findViewById(R.id.Submit);

You need to cast your activity from getActivity() to AppCompatActivity first. Here's an example:

((AppCompatActivity) getActivity()).getSupportActionBar().setTitle();

The reason you have to cast it is because getActivity() returns a FragmentActivity and you need an AppCompatActivity

In Kotlin:

(activity as AppCompatActivity).supportActionBar?.title = "My Title"

This is how I do it to return to the right fragment otherwise if you have several fragments on the same level it would return to the first one if you don´t override the toolbar back button behavior.

toolbar.setNavigationOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            finish();
        }
    });

you must use import android.support.v7.app.ActionBarDrawerToggle;

and use the constructor

public CustomActionBarDrawerToggle(Activity mActivity,DrawerLayout mDrawerLayout)
{
    super(mActivity, mDrawerLayout, R.string.ns_menu_open, R.string.ns_menu_close);
}

and if the drawer toggle button becomes dark then you must use the supportActionBar provided in the support library.

You can implement supportActionbar from this link: http://developer.android.com/training/basics/actionbar/setting-up.html

OnFragmentInteractionListener is the default implementation for handling fragment to activity communication. This can be implemented based on your needs. Suppose if you need a function in your activity to be executed during a particular action within your fragment, you may make use of this callback method. If you don't need to have this interaction between your hosting activity and fragment, you may remove this implementation.

In short you should implement the listener in your fragment hosting activity if you need the fragment-activity interaction like this

public class MainActivity extends Activity implements 
YourFragment.OnFragmentInteractionListener {..}

and your fragment should have it defined like this

public interface OnFragmentInteractionListener {
    // TODO: Update argument type and name
    void onFragmentInteraction(Uri uri);
}

also provide definition for void onFragmentInteraction(Uri uri); in your activity

or else just remove the listener initialisation from your fragment's onAttach if you dont have any fragment-activity interaction

I have the same problem because I did not implement the listener. See the following code with /*Add This!*/.

public class SomeActivity extends AppCompatActivity
        implements BlankFragment.OnFragmentInteractionListener /*Add this!*/ 
{
    @Override                                                  /*Add This!*/
    public void onFragmentInteraction(Uri uri){                /*Add This!*/
    }                                                          /*Add This!*/
}

FYI, my fragment class is something like the following:

public class SomeFragment extends Fragment {

    private OnFragmentInteractionListener mListener;

    @Override
    public void onAttach(Activity activity) {
        super.onAttach(activity);
        try {
            mListener = (OnFragmentInteractionListener) activity;
        } catch (ClassCastException e) {
            throw new ClassCastException(activity.toString()
                    + " must implement OnFragmentInteractionListener");
        }
    }

    public interface OnFragmentInteractionListener {
        public void onFragmentInteraction(Uri uri);
    }
}

Edit:

I also notice this same error message under another circumstances when there is an exception in the onCreate function of the Fragment. I have something as the following:

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    View rootView = inflater.inflate(R.layout.fragment_main, container, false);

    int ID = getArguments().getInt("val");

    return rootView;
} 

Because I reuse this fragment, I total forget to set arguments. Then the result of getArguments() is null. Obviously, I get a null pointer exception here. I will suggest you keep an eye on mistakes like this as well.

</RelativeLayout>

actually, your answer is not complete as the values also depend on the wrapping container. In case of relative or linear layouts, the values behave like this:

• EXACTLY match_parent is EXACTLY + size of the parent
• AT_MOST wrap_content results in an AT_MOST MeasureSpec
• UNSPECIFIED never triggered

In case of an horizontal scroll view, your code will work.

I find that the best solution for centering text is as follows:

textPaint.setTextAlign(Paint.Align.CENTER);
//textPaint is the Paint object being used to draw the text (it must be initialized beforehand)
float textY=center.y;
float textX=center.x; 
// in this case, center.x and center.y represent the coordinates of the center of the rectangle in which the text is being placed
canvas.drawText(text,textX,textY,textPaint);    `

Using a ScaleGestureDetector

When learning a new concept I don't like using libraries or code dumps. I found a good description here and in the documentation of how to resize an image by pinching. This answer is a slightly modified summary. You will probably want to add more functionality later, but it will help you get started.

Layout

The ImageView just uses the app logo since it is already available. You can replace it with any image you like, though.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ImageView
        android:id="@+id/imageView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:src="@mipmap/ic_launcher"
        android:layout_centerInParent="true"/>

</RelativeLayout>

Activity

We use a ScaleGestureDetector on the activity to listen to touch events. When a scale (ie, pinch) gesture is detected, then the scale factor is used to resize the ImageView.

public class MainActivity extends AppCompatActivity {

    private ScaleGestureDetector mScaleGestureDetector;
    private float mScaleFactor = 1.0f;
    private ImageView mImageView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // initialize the view and the gesture detector
        mImageView = findViewById(R.id.imageView);
        mScaleGestureDetector = new ScaleGestureDetector(this, new ScaleListener());
    }

    // this redirects all touch events in the activity to the gesture detector
    @Override
    public boolean onTouchEvent(MotionEvent event) {
        return mScaleGestureDetector.onTouchEvent(event);
    }

    private class ScaleListener extends ScaleGestureDetector.SimpleOnScaleGestureListener {

        // when a scale gesture is detected, use it to resize the image
        @Override
        public boolean onScale(ScaleGestureDetector scaleGestureDetector){
            mScaleFactor *= scaleGestureDetector.getScaleFactor();
            mImageView.setScaleX(mScaleFactor);
            mImageView.setScaleY(mScaleFactor);
            return true;
        }
    }
}

Notes

• Although the activity had the gesture detector in the example above, it could have also been set on the image view itself.

• You can limit the size of the scaling with something like

  mScaleFactor = Math.max(0.1f, Math.min(mScaleFactor, 5.0f));
  

• Thanks again to Pinch-to-zoom with multi-touch gestures In Android

• Documentation
• Use Ctrl + mouse drag to simulate a pinch gesture in the emulator.

Going on

You will probably want to do other things like panning and scaling to some focus point. You can develop these things yourself, but if you would like to use a pre-made custom view, copy TouchImageView.java into your project and use it like a normal ImageView. It worked well for me and I only ran into one bug. I plan to further edit the code to remove the warning and the parts that I don't need. You can do the same.

Starting with Android 4.x, Android team fixed a potential security problem by adding a new function adjustWindowParamsLw() in which it will add FLAG_NOT_FOCUSABLE, FLAG_NOT_TOUCHABLE and remove FLAG_WATCH_OUTSIDE_TOUCH flags for TYPE_SYSTEM_OVERLAY windows.

That is, a TYPE_SYSTEM_OVERLAY window won't receive any touch event on ICS platform and, of course, to use TYPE_SYSTEM_OVERLAY is not a workable solution for ICS and future devices.

From the Android Docs -

onLongClick()

From View.OnLongClickListener. This is called when the user either touches and holds the item (when in touch mode), or focuses upon the item with the navigation-keys or trackball and presses and holds the suitable "enter" key or presses and holds down on the trackball (for one second).

onTouch()

From View.OnTouchListener. This is called when the user performs an action qualified as a touch event, including a press, a release, or any movement gesture on the screen (within the bounds of the item).

As for the "moving happens even when I touch" I would set a delta and make sure the View has been moved by at least the delta before kicking in the movement code. If it hasn't been, kick off the touch code.

Just follow this order

You can center any number of child in a FrameLayout.

<FrameLayout
    >
    <child1
        ....
        android:layout_gravity="center"
        .....
        />
    <Child2
        ....
        android:layout_gravity="center"
        />
</FrameLayout>

So the key is

adding android:layout_gravity="center"in the child views.

For example:

I centered a CustomView and a TextView on a FrameLayout like this

Code:

<FrameLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    >
    <com.airbnb.lottie.LottieAnimationView
        android:layout_width="180dp"
        android:layout_height="180dp"
        android:layout_gravity="center"
        app:lottie_fileName="red_scan.json"
        app:lottie_autoPlay="true"
        app:lottie_loop="true" />
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:textColor="#ffffff"
        android:textSize="10dp"
        android:textStyle="bold"
        android:padding="10dp"
        android:text="Networks Available: 1\n click to see all"
        android:gravity="center" />
</FrameLayout>

One possible solution:-

Summary: make sure you are using import com.yourpkgdomainname.yourpkgappname.R instead of import android.R

Details: The problem occured when I changed ID of a label which was being referred in other places in the layout XML file. Due to this error, the R file stopped generating at first. Eclipse is bad in handling errors with the layout files.

When I corrected the ID reference (with project clean few times and Eclipse restarts, I noticed that my import packages now has:
import android.R

Changing it to following fixed the error:
import com.example.app.R

SurfaceView probably does not work like a regular View in this regard.

Instead, do the following:

1. Put your SurfaceView inside of a FrameLayout or RelativeLayout in your layout XML file, since both of those allow stacking of widgets on the Z-axis
2. Move your drawing logic into a separate custom View class
3. Add an instance of the custom View class to the layout XML file as a child of the FrameLayout or RelativeLayout, but have it appear after the SurfaceView

This will cause your custom View class to appear to float above the SurfaceView.

See here for a sample project that layers popup panels above a SurfaceView used for video playback.

It should be noted that the documentation recommends using a Layout rather than Canvas.drawText directly. My full answer about using a StaticLayout is here, but I will provide a summary below.

String text = "This is some text.";

TextPaint textPaint = new TextPaint();
textPaint.setAntiAlias(true);
textPaint.setTextSize(16 * getResources().getDisplayMetrics().density);
textPaint.setColor(0xFF000000);

int width = (int) textPaint.measureText(text);
StaticLayout staticLayout = new StaticLayout(text, textPaint, (int) width, Layout.Alignment.ALIGN_NORMAL, 1.0f, 0, false);
staticLayout.draw(canvas);

Here is a fuller example in the context of a custom view:

public class MyView extends View {

    String mText = "This is some text.";
    TextPaint mTextPaint;
    StaticLayout mStaticLayout;

    // use this constructor if creating MyView programmatically
    public MyView(Context context) {
        super(context);
        initLabelView();
    }

    // this constructor is used when created from xml
    public MyView(Context context, AttributeSet attrs) {
        super(context, attrs);
        initLabelView();
    }

    private void initLabelView() {
        mTextPaint = new TextPaint();
        mTextPaint.setAntiAlias(true);
        mTextPaint.setTextSize(16 * getResources().getDisplayMetrics().density);
        mTextPaint.setColor(0xFF000000);

        // default to a single line of text
        int width = (int) mTextPaint.measureText(mText);
        mStaticLayout = new StaticLayout(mText, mTextPaint, (int) width, Layout.Alignment.ALIGN_NORMAL, 1.0f, 0, false);

        // New API alternate
        //
        // StaticLayout.Builder builder = StaticLayout.Builder.obtain(mText, 0, mText.length(), mTextPaint, width)
        //        .setAlignment(Layout.Alignment.ALIGN_NORMAL)
        //        .setLineSpacing(1, 0) // multiplier, add
        //        .setIncludePad(false);
        // mStaticLayout = builder.build();
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        // Tell the parent layout how big this view would like to be
        // but still respect any requirements (measure specs) that are passed down.

        // determine the width
        int width;
        int widthMode = MeasureSpec.getMode(widthMeasureSpec);
        int widthRequirement = MeasureSpec.getSize(widthMeasureSpec);
        if (widthMode == MeasureSpec.EXACTLY) {
            width = widthRequirement;
        } else {
            width = mStaticLayout.getWidth() + getPaddingLeft() + getPaddingRight();
            if (widthMode == MeasureSpec.AT_MOST) {
                if (width > widthRequirement) {
                    width = widthRequirement;
                    // too long for a single line so relayout as multiline
                    mStaticLayout = new StaticLayout(mText, mTextPaint, width, Layout.Alignment.ALIGN_NORMAL, 1.0f, 0, false);
                }
            }
        }

        // determine the height
        int height;
        int heightMode = MeasureSpec.getMode(heightMeasureSpec);
        int heightRequirement = MeasureSpec.getSize(heightMeasureSpec);
        if (heightMode == MeasureSpec.EXACTLY) {
            height = heightRequirement;
        } else {
            height = mStaticLayout.getHeight() + getPaddingTop() + getPaddingBottom();
            if (heightMode == MeasureSpec.AT_MOST) {
                height = Math.min(height, heightRequirement);
            }
        }

        // Required call: set width and height
        setMeasuredDimension(width, height);
    }

    @Override
    protected void onDraw(Canvas canvas) {
        super.onDraw(canvas);
        // do as little as possible inside onDraw to improve performance

        // draw the text on the canvas after adjusting for padding
        canvas.save();
        canvas.translate(getPaddingLeft(), getPaddingTop());
        mStaticLayout.draw(canvas);
        canvas.restore();
    }
}

This is full source code to draw direction path from source latitude and longitude to destination latitude and longitude. I have changed the above code to fit for latitude and longitude rather than source and destination. So anyone who is accessing his latitude and longitude through his gps can get the direction from his gps device to the destination coordinates.

Thanks to above answers we could make such a change and get path direction.

suppose you don't have column for auto increment like id, no, then you can add using following query:

ALTER TABLE table_name ADD id int NOT NULL AUTO_INCREMENT primary key FIRST

If you've column, then alter to auto increment using following query:

 ALTER TABLE table_name MODIFY column_name datatype(length) AUTO_INCREMENT PRIMARY KEY

This problem is generally caused by the website/intranet URL being placed in one of:

• Compatibility Mode List
• Internet Explorer Intranet Zone
  (with Display intranet sites in Compatibility View setting enabled)
• Enterprise Mode List

On corporate networks, these compatibility view settings are often controlled centrally via group policy. In your case, Enterprise Mode appears to be the culprit.

Unfortunately setting META X-UA-Compatible will not override this.

For End-Users

Sometimes the only way for end-users to override this is to press F12 and change the Document Mode under the Emulation Tab. However this setting is not permanent and may revert once Developer Tools is closed.

You can also try to exclude your site from the Intranet zone. But the list of domains which belong to the Intranet zone is usually also controlled by the group policy, so the chance of this working is slim.

To see the list of domains that belong to the Intranet zone, go to:

Tools -> Internet Options -> Security -> Sites -> Advanced

If the list contains your subdomain and is greyed out, then you will not be able to override compatibility view until your network admin allows it.

You really need to contact your network administrator to allow changing the compatibility view settings in the group policy.

For Network Admins

Loading the website with Developer Tools open (F12) will often report the reason that IE is switching to an older mode.

All 3 settings mentioned above are generally controlled via Group Policy, although can sometimes be overridden on user machines.

If Enterprise Mode is the issue (as appears to be the case for the original poster), the following two articles might be helpful:

• How to Enable and Use Internet Explorer 11’s Enterprise Mode [HowToGeek]
• Turn on Enterprise Mode and use a site list [TechNet]

I think the accepted answer is great, but why don't you do it explicitly? I feel more people would understand your code, and that is in agreement with PEP 8:

max_value = max(my_list)
max_index = my_list.index(max_value)

This method is also about three times faster than the accepted answer:

import random
from datetime import datetime
import operator

def explicit(l):
    max_val = max(l)
    max_idx = l.index(max_val)
    return max_idx, max_val

def implicit(l):
    max_idx, max_val = max(enumerate(l), key=operator.itemgetter(1))
    return max_idx, max_val

if __name__ == "__main__":
    from timeit import Timer
    t = Timer("explicit(l)", "from __main__ import explicit, implicit; "
          "import random; import operator;"
          "l = [random.random() for _ in xrange(100)]")
    print "Explicit: %.2f usec/pass" % (1000000 * t.timeit(number=100000)/100000)

    t = Timer("implicit(l)", "from __main__ import explicit, implicit; "
          "import random; import operator;"
          "l = [random.random() for _ in xrange(100)]")
    print "Implicit: %.2f usec/pass" % (1000000 * t.timeit(number=100000)/100000)

Results as they run in my computer:

Explicit: 8.07 usec/pass
Implicit: 22.86 usec/pass

Other set:

Explicit: 6.80 usec/pass
Implicit: 19.01 usec/pass

docker logs -f <yourContainer> &> your.log &

Explanation:

• -f (i.e.--follow): writes all existing logs and continues (follows) logging everything that comes next.
• &> redirects both the standard output and standard error.
• Likely you want to run that method in the background, thus the &.
• You can separate output and stderr by: > output.log 2> error.log (instead of using &>).

In my case I was using it on localhost and forgot to change RewriteBase in .htaccess.

From the openssl.pc file

prefix=/usr
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/include

Name: OpenSSL
Description: Secure Sockets Layer and cryptography libraries and tools
Version: 0.9.8g
Requires:
Libs: -L${libdir} -lssl -lcrypto
Libs.private: -ldl -Wl,-Bsymbolic-functions -lz
Cflags: -I${includedir}

You can note the Include directory path and the Libs path from this. Now your prefix for the include files is /home/username/Programming . Hence your include file option should be -I//home/username/Programming.

(Yes i got it from the comments above)

This is just to remove logs regarding the headers. You may as well provide -L<Lib path> option for linking with the -lcrypto library.

Here is how to make a 2 dimensional list

        // Generating lists in a loop.
        List<List<string>> biglist = new List<List<string>>();

        for(int i = 1; i <= 10; i++)
        {
            List<string> list1 = new List<string>();
            biglist.Add(list1);
        }

        // Populating the lists
        for (int i = 0; i < 10; i++)
        {
            for(int j = 0; j < 10; j++)
            {
                biglist[i].Add((i).ToString() + " " + j.ToString());
            }
        }

        textbox1.Text = biglist[5][9] + "\n";

Be aware of the danger of accessing a location that is not populated.

If you knew C# and XNA, you could make some sample games in a pretty straight forward manner, which might help to break into the field.

My guess is, the core gaming engines are written in C++, but some of the other code around the core could be in C#.

A simpler approach relies on redirection from the page LOGIN_REDIRECT_URL. The key thing to realize is that the user information is automatically included in the request.

Suppose:

LOGIN_REDIRECT_URL = '/profiles/home'

and you have configured a urlpattern:

(r'^profiles/home', home),

Then, all you need to write for the view home() is:

from django.http import HttpResponseRedirect
from django.urls import reverse
from django.contrib.auth.decorators import login_required

@login_required
def home(request):
    return HttpResponseRedirect(
               reverse(NAME_OF_PROFILE_VIEW, 
                       args=[request.user.username]))

where NAME_OF_PROFILE_VIEW is the name of the callback that you are using. With django-profiles, NAME_OF_PROFILE_VIEW can be 'profiles_profile_detail'.

I've found that using a simple for loop, iterating over all elements in the string and comparing using charAt performs faster than indexOf or Regex. The code and proof is available at JSPerf.

ETA: indexOf and charAt both perform similarly terrible on Chrome Mobile according to Browser Scope data listed on jsperf.com

Instagram now allows businesses to schedule their posts, using the new Content Publishing Beta endpoints.

https://developers.facebook.com/blog/post/2018/01/30/instagram-graph-api-updates/

However, this blog post - https://business.instagram.com/blog/instagram-api-features-updates - makes it clear that they are only opening that API to their Facebook Marketing Partners or Instagram Partners.

To get started with scheduling posts, please work with one of our Facebook Marketing Partners or Instagram Partners.

This link from Facebook - https://developers.facebook.com/docs/instagram-api/content-publishing - lists it as a closed beta.

The Content Publishing API is in closed beta with Facebook Marketing Partners and Instagram Partners only. We are not accepting new applicants at this time.

But this is how you would do it:

You have a photo at...

https://www.example.com/images/bronz-fonz.jpg

You want to publish it with the hashtag "#BronzFonz".

You could use the /user/media edge to create the container like this:

POST graph.facebook.com 
  /17841400008460056/media?
    image_url=https%3A%2F%2Fwww.example.com%2Fimages%2Fbronz-fonz.jpg&
    caption=%23BronzFonz

This would return a container ID (let's say 17889455560051444), which you would then publish using the /user/media_publish edge, like this:

POST graph.facebook.com
  /17841405822304914/media_publish
    ?creation_id=17889455560051444

This example from the docs.

After looking at all the suggestions here, I've discovered a few things which I hope will be useful to others in my position:

1. hop is right to point me back at /etc/init.d/functions: the daemon function already allows you to set an alternate user:

   daemon --user=my_user my_cmd &>/dev/null &
   

   This is implemented by wrapping the process invocation with runuser - more on this later.

2. Jonathan Leffler is right: there is setuid in Python:

   import os
   os.setuid(501) # UID of my_user is 501
   

   I still don't think you can setuid from inside a JVM, however.

3. Neither su nor runuser gracefully handle the case where you ask to run a command as the user you already are. E.g.:

   [my_user@my_host]$ id
   uid=500(my_user) gid=500(my_user) groups=500(my_user)
   [my_user@my_host]$ su my_user -c "id"
   Password: # don't want to be prompted!
   uid=500(my_user) gid=500(my_user) groups=500(my_user)
   

To workaround that behaviour of su and runuser, I've changed my init script to something like:

if [[ "$USER" == "my_user" ]]
then
    daemon my_cmd &>/dev/null &
else
    daemon --user=my_user my_cmd &>/dev/null &
fi

Thanks all for your help!

I recently started receiving this error inside of my internal NLog failures log, with Visual Studio 2013. The solution has been using NLog v2.0.0 for several years. Within the last month, our main log stopped working. To fix this I updated NLog to the newest version (v3.1.0) via Nuget. The security exception is now gone and ALL of the log messages are appearing again.

Additionally, I later found another Security exception and was able to fix it by following the instructions on this post in another thread.

In postgresql you can use regular expressions in WHERE clause. Check http://www.postgresql.org/docs/8.4/static/functions-matching.html

MySQL has something simmilar: http://dev.mysql.com/doc/refman/5.5/en/regexp.html

Use the GeoCoding API

For example, to lookup zip 77379 use a request like this:

https://maps.googleapis.com/maps/api/geocode/json?address=77379&sensor=true&key=YOUR_GOOGLE_PLATFORM_API_KEY

This is my solution for your reference:

struct Foo
{
    Foo(){}//used to make compiler happy!
    Foo(int x){/*...*/}
};

struct Bar
{
    Foo foo[3];

    Bar()
    {
        //initialize foo array here:
        for(int i=0;i<3;++i)
        {
            foo[i]=Foo(4+i);
        }
    }
};

The Random class of Java located in the java.util package will serve your purpose better. It has some nextInt() methods that return an integer. The one taking an int argument will generate a number between 0 and that int, the latter not inclusive.

char originalString[] = "THESTRINGHASNOSPACES";

    char aux[5];
    int j=0;
    for(int i=0;i<strlen(originalString);i++){
        aux[j] = originalString[i];
        if(j==3){
            aux[j+1]='\0'; 
            printf("%s\n",aux);
            j=0;
        }else{
            j++;
        }
    }

var handle = setInterval(changeIframe, 30000);
var sites = ["google.com", "yahoo.com"];
var index = 0;

function changeIframe() {
  $('#frame')[0].src = sites[index++];
  index = index >= sites.length ? 0 : index;
}

Let us use the following image as an example for the data in our MySQL Database:

Now, as the question mentions, we need to find the sum of a particular column in a table. For example, let us add all the values of column "duration_sec" for the date '09-10-2018' and only status 'off'

For this condition, the following would be the sql query and code:

$sql_qry = "SELECT SUM(duration_sec) AS count 
    FROM tbl_npt 
    WHERE date='09-10-2018' AND status='off'";

$duration = $connection->query($sql_qry);
$record = $duration->fetch_array();
$total = $record['count'];

echo $total;

The program immediately closes because there's nothing stopping it from closing. Insert a breakpoint at return 0; or add Console.Read(); before return 0; to prevent the program from closing.

Just to answer the add() vs offer() question (since the other one is perfectly answered imo, and this might not be):

According to JavaDoc on interface Queue, "The offer method inserts an element if possible, otherwise returning false. This differs from the Collection.add method, which can fail to add an element only by throwing an unchecked exception. The offer method is designed for use when failure is a normal, rather than exceptional occurrence, for example, in fixed-capacity (or "bounded") queues."

That means if you can add the element (which should always be the case in a PriorityQueue), they work exactly the same. But if you can't add the element, offer() will give you a nice and pretty false return, while add() throws a nasty unchecked exception that you don't want in your code. If failure to add means code is working as intended and/or it is something you'll check normally, use offer(). If failure to add means something is broken, use add() and handle the resulting exception thrown according to the Collection interface's specifications.

They are both implemented this way to fullfill the contract on the Queue interface that specifies offer() fails by returning a false (method preferred in capacity-restricted queues) and also maintain the contract on the Collection interface that specifies add() always fails by throwing an exception.

Anyway, hope that clarifies at least that part of the question.

Eclipse does not search if the "File name patterns" field is empty.
So, if you want to search some text, write within "Containing text" field and leave
by default "File name patterns" with asterisk (*).

Easiest for me to remember is two operations:

chmod -R 644 dirName
chmod -R +X dirName

The +X only affects directories.

There are a number of properties on the StringComparer static class that return comparers for any type of case-sensitivity you might want:

StringComparer Properties

For instance, you can call

StringComparer.CurrentCultureIgnoreCase.Equals(string1, string2)

or

StringComparer.CurrentCultureIgnoreCase.Compare(string1, string2)

It's a bit cleaner than the string.Equals or string.Compare overloads that take a StringComparison argument.

It is changed to : from PIL.Image import core as image for new versions.

put the following in the site's .htaccess file (in the /var/www/XXX):

Header set Access-Control-Allow-Origin "*"

instead of the .conf file.

You'll also want to use

AllowOverride All

in your .conf file for the domain so Apache looks at it.

Retrofit 2.0 solution

@Multipart
@POST(APIUtils.UPDATE_PROFILE_IMAGE_URL)
public Call<CommonResponse> requestUpdateImage(@PartMap Map<String, RequestBody> map);

and

    Map<String, RequestBody> params = new HashMap<>();

    params.put("newProfilePicture" + "\"; filename=\"" + FilenameUtils.getName(file.getAbsolutePath()), RequestBody.create(MediaType.parse("image/jpg"), file));



 Call<CommonResponse> call = request.requestUpdateImage(params);

you can use
image/jpg image/png image/gif

The regular expression for this is really simple. Just use a character class. The hyphen is a special character in character classes, so it needs to be first:

/[-!$%^&*()_+|~=`{}\[\]:";'<>?,.\/]/

You also need to escape the other regular expression metacharacters.

Edit: The hyphen is special because it can be used to represent a range of characters. This same character class can be simplified with ranges to this:

/[$-/:-?{-~!"^_`\[\]]/

There are three ranges. '$' to '/', ':' to '?', and '{' to '~'. the last string of characters can't be represented more simply with a range: !"^_`[].

Use an ACSII table to find ranges for character classes.

For me, I think my solution just got caught in a weird state when I was changing which branch of my local Git repo I was on. Simply switching to the previous branch I was on before the problem started, telling VS to reload all the files, then switching back to the desired branch and reloading again fixed it.

I did like David Brown said but I got the following exception.

$exception {"There are multiple root elements. Line , position ."} System.Xml.XmlException

One solution would be to modify the XML file with a root element but that is not always necessary and for an XML stream it might not be possible either. My solution below:

var path = Path.GetFullPath(Path.Combine(Environment.CurrentDirectory, @"..\..\App_Data"));
var directoryInfo = new DirectoryInfo(path);
var fileInfos = directoryInfo.GetFiles("*.xml");

foreach (var fileInfo in fileInfos)
{
    XmlDocument doc = new XmlDocument();
    XmlReaderSettings settings = new XmlReaderSettings();
    settings.ConformanceLevel = ConformanceLevel.Fragment;

    using (XmlReader reader = XmlReader.Create(fileInfo.FullName, settings))
    {
        while (reader.Read())
        {
            if (reader.NodeType == XmlNodeType.Element)
            {
                var node = doc.ReadNode(reader);
                string json = JsonConvert.SerializeXmlNode(node);
            }
        }
    }
}

Example XML that generates the error:

<parent>
    <child>
        Text
    </child>
</parent>
<parent>
    <child>
        <grandchild>
            Text
        </grandchild>
        <grandchild>
            Text
        </grandchild>
    </child>
    <child>
        Text
    </child>
</parent>

Simply remove the virtual environment from the system.There's no special command for it

rm -rf venv

The NameValueCollection supports multiple string values under one key (which is also a string), but it is the only example I am aware of.

I tend to create constructs similar to the one in your example when I run into situations where I need that sort of functionality.

@AHegde - To get the tab delimited output use separator sep='\t'.

For df.to_csv:

df.to_csv(r'c:\data\pandas.txt', header=None, index=None, sep='\t', mode='a')

For np.savetxt:

np.savetxt(r'c:\data\np.txt', df.values, fmt='%d', delimiter='\t')

Try this one

UPDATE employee 
set EMPLOYEE.MAIDEN_NAME = 
  (SELECT ADD1 
   FROM EMPS 
   WHERE EMP_CODE=EMPLOYEE.EMP_CODE);
WHERE EMPLOYEE.EMP_CODE >='00' 
AND EMPLOYEE.EMP_CODE <='ZZ';

If you have a string like foo: 1, bar: 2 you can convert it to a valid obj with:

str
  .split(',')
  .map(x => x.split(':').map(y => y.trim()))
  .reduce((a, x) => {
    a[x[0]] = x[1];
    return a;
  }, {});

Thanks to niggler in #javascript for that.

Update with explanations:

const obj = 'foo: 1, bar: 2'
  .split(',') // split into ['foo: 1', 'bar: 2']
  .map(keyVal => { // go over each keyVal value in that array
    return keyVal
      .split(':') // split into ['foo', '1'] and on the next loop ['bar', '2']
      .map(_ => _.trim()) // loop over each value in each array and make sure it doesn't have trailing whitespace, the _ is irrelavent because i'm too lazy to think of a good var name for this
  })
  .reduce((accumulator, currentValue) => { // reduce() takes a func and a beginning object, we're making a fresh object
    accumulator[currentValue[0]] = currentValue[1]
    // accumulator starts at the beginning obj, in our case {}, and "accumulates" values to it
    // since reduce() works like map() in the sense it iterates over an array, and it can be chained upon things like map(),
    // first time through it would say "okay accumulator, accumulate currentValue[0] (which is 'foo') = currentValue[1] (which is '1')
    // so first time reduce runs, it starts with empty object {} and assigns {foo: '1'} to it
    // second time through, it "accumulates" {bar: '2'} to it. so now we have {foo: '1', bar: '2'}
    return accumulator
  }, {}) // when there are no more things in the array to iterate over, it returns the accumulated stuff

console.log(obj)

Confusing MDN docs:

• https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/map
• https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/Reduce

    })
    .reduce((accumulator, currentValue) => {
      accumulator[currentValue[0]] = currentValue[1]
      return accumulator
    }, {})
}

console.log(str2obj('foo: 1, bar: 2')) // see? works!

If we don't know anything about those numbers, we are limited by the following constraints:

• we need to load all numbers before we can sort them them,
• the set of numbers is not compressible.

If these assumptions hold, there is no way to carry out your task, as you will need at least 26,575,425 bits of storage (3,321,929 bytes).

What can you tell us about your data ?

The block approach avoids running the lookup algorithm for every key:

[dict enumerateKeysAndObjectsUsingBlock:^(id key, id value, BOOL* stop) {
  NSLog(@"%@ => %@", key, value);
}];

Even though NSDictionary is implemented as a hashtable (which means that the cost of looking up an element is O(1)), lookups still slow down your iteration by a constant factor.

My measurements show that for a dictionary d of numbers ...

NSMutableDictionary* dict = [NSMutableDictionary dictionary];
for (int i = 0; i < 5000000; ++i) {
  NSNumber* value = @(i);
  dict[value.stringValue] = value;
}

... summing up the numbers with the block approach ...

__block int sum = 0;
[dict enumerateKeysAndObjectsUsingBlock:^(NSString* key, NSNumber* value, BOOL* stop) {
  sum += value.intValue;
}];

... rather than the loop approach ...

int sum = 0;
for (NSString* key in dict)
  sum += [dict[key] intValue];

... is about 40% faster.

EDIT: The new SDK (6.1+) appears to optimise loop iteration, so the loop approach is now about 20% faster than the block approach, at least for the simple case above.

You can only use await in an async method, and Main cannot be async.

You'll have to use your own async-compatible context, call Wait on the returned Task in the Main method, or just ignore the returned Task and just block on the call to Read. Note that Wait will wrap any exceptions in an AggregateException.

If you want a good intro, see my async/await intro post.

this work for me and (version 13.0.6.1911 64 bit)

You can use this outside activities - all you need is to provide a Context:

LayoutInflater inflater = (LayoutInflater) context.getSystemService( Context.LAYOUT_INFLATER_SERVICE );

Then to retrieve your different widgets, you inflate a layout:

View view = inflater.inflate( R.layout.myNewInflatedLayout, null );
Button myButton = (Button) view.findViewById( R.id.myButton );

EDIT as of July 2014

Davide's answer on how to get the LayoutInflater is actually more correct than mine (which is still valid though).

Frankly the errors are really hard to see, especially if only one character is "underwaved" in a sea of Java code. I used the instructions above to make the background an orangey-red color and things are much more obvious.

Since PostgreSQL 9.1 there is the convenient FOREACH:

DO
$do$
DECLARE
   m   varchar[];
   arr varchar[] := array[['key1','val1'],['key2','val2']];
BEGIN
   FOREACH m SLICE 1 IN ARRAY arr
   LOOP
      RAISE NOTICE 'another_func(%,%)',m[1], m[2];
   END LOOP;
END
$do$

Solution for older versions:

DO
$do$
DECLARE
   arr varchar[] := '{{key1,val1},{key2,val2}}';
BEGIN
   FOR i IN array_lower(arr, 1) .. array_upper(arr, 1)
   LOOP
      RAISE NOTICE 'another_func(%,%)',arr[i][1], arr[i][2];
   END LOOP;
END
$do$

Also, there is no difference between varchar[] and varchar[][] for the PostgreSQL type system. I explain in more detail here.

The DO statement requires at least PostgreSQL 9.0, and LANGUAGE plpgsql is the default (so you can omit the declaration).

Steps to generate Create table DDLs for all the tables in the Hive database and export into text file to run later:

step 1)
create a .sh file with the below content, say hive_table_ddl.sh

#!/bin/bash
rm -f tableNames.txt
rm -f HiveTableDDL.txt
hive -e "use $1; show tables;" > tableNames.txt  
wait
cat tableNames.txt |while read LINE
   do
   hive -e "use $1;show create table $LINE;" >>HiveTableDDL.txt
   echo  -e "\n" >> HiveTableDDL.txt
   done
rm -f tableNames.txt
echo "Table DDL generated"

step 2)

Run the above shell script by passing 'db name' as paramanter

>bash hive_table_dd.sh <<databasename>>

output :

All the create table statements of your DB will be written into the HiveTableDDL.txt

FYI: You could get a similar behavior to what you want by creating extension methods for the interface. The extension method would be a shared, non overridable static behavior. However, unfortunately, this static method would not be part of the contract.

Another poossible solution is based on the array_search() function. You need to use PHP 5.5.0 or higher.

Example

$userdb=Array
(
(0) => Array
    (
        (uid) => '100',
        (name) => 'Sandra Shush',
        (url) => 'urlof100'
    ),

(1) => Array
    (
        (uid) => '5465',
        (name) => 'Stefanie Mcmohn',
        (pic_square) => 'urlof100'
    ),

(2) => Array
    (
        (uid) => '40489',
        (name) => 'Michael',
        (pic_square) => 'urlof40489'
    )
);

$key = array_search(40489, array_column($userdb, 'uid'));

echo ("The key is: ".$key);
//This will output- The key is: 2

Explanation

The function array_search() has two arguments. The first one is the value that you want to search. The second is where the function should search. The function array_column() gets the values of the elements which key is 'uid'.

Summary

So you could use it as:

array_search('breville-one-touch-tea-maker-BTM800XL', array_column($products, 'slug'));

or, if you prefer:

// define function
function array_search_multidim($array, $column, $key){
    return (array_search($key, array_column($array, $column)));
}

// use it
array_search_multidim($products, 'slug', 'breville-one-touch-tea-maker-BTM800XL');

The original example(by xfoxawy) can be found on the DOCS.
The array_column() page.

Update

Due to Vael comment I was curious, so I made a simple test to meassure the performance of the method that uses array_search and the method proposed on the accepted answer.

I created an array which contained 1000 arrays, the structure was like this (all data was randomized):

[
      {
            "_id": "57fe684fb22a07039b3f196c",
            "index": 0,
            "guid": "98dd3515-3f1e-4b89-8bb9-103b0d67e613",
            "isActive": true,
            "balance": "$2,372.04",
            "picture": "http://placehold.it/32x32",
            "age": 21,
            "eyeColor": "blue",
            "name": "Green",
            "company": "MIXERS"
      },...
]

I ran the search test 100 times searching for different values for the name field, and then I calculated the mean time in milliseconds. Here you can see an example.

Results were that the method proposed on this answer needed about 2E-7 to find the value, while the accepted answer method needed about 8E-7.

Like I said before both times are pretty aceptable for an application using an array with this size. If the size grows a lot, let's say 1M elements, then this little difference will be increased too.

Update II

I've added a test for the method based in array_walk_recursive which was mentionend on some of the answers here. The result got is the correct one. And if we focus on the performance, its a bit worse than the others examined on the test. In the test, you can see that is about 10 times slower than the method based on array_search. Again, this isn't a very relevant difference for the most of the applications.

Update III

Thanks to @mickmackusa for spotting several limitations on this method:

• This method will fail on associative keys.
• This method will only work on indexed subarrays (starting from 0 and have consecutively ascending keys).

Open Tools -> Options -> Keymap, then look for the action called "Re-indent current line or selection" and set whatever shortcut you want.

The LDF stand for 'Log database file' and it is the transaction log. It keeps a record of everything done to the database for rollback purposes, you can restore a database even you lost .msf file because it contain all control information plus transaction information .

why do I have to pass seconds = uptime to timedelta

Because timedelta objects can be passed seconds, milliseconds, days, etc... so you need to specify what are you passing in (this is why you use the explicit key). Typecasting to int is superfluous as they could also accept floats.

and why does the string casting works so nicely that I get HH:MM:SS ?

It's not the typecasting that formats, is the internal __str__ method of the object. In fact you will achieve the same result if you write:

print datetime.timedelta(seconds=int(uptime))

* for python 2.x *

Use a trailing comma to avoid a newline.

print "Hey Guys!",
print "This is how we print on the same line."

The output for the above code snippet would be,

Hey Guys! This is how we print on the same line.

* for python 3.x *

for i in range(10):
    print(i, end="<separator>") # <separator> = \n, <space> etc.

The output for the above code snippet would be (when <separator> = " "),

0 1 2 3 4 5 6 7 8 9

If you don't have the token at the time of the call is made, You will have to make two calls, one to get the token and the other to extract the token form the response, pay attention to

grep token | cut -d, -f1 | cut -d\" -f4

as it is the part which is dealing with extracting the token from the response.

echo "Getting token response and extracting token"    
def token = sh (returnStdout: true, script: """
    curl -S -i -k -X POST https://www.example.com/getToken -H \"Content-Type: application/json\" -H \"Accept: application/json\" -d @requestFile.json | grep token | cut -d, -f1 | cut -d\\" -f4
""").split()

After extracting the token you can use the token to make subsequent calls as follows.

echo "Token : ${token[-1]}"       
echo "Making calls using token..."       
curl -S -i -k  -H "Accept: application/json" -H "Content-Type: application/json" -H "Authorization: Bearer ${token[-1]}" https://www.example.com/api/resources 

This should work:

SELECT * 
INTO DestinationDB..MyDestinationTable 
FROM SourceDB..MySourceTable 

It will not copy constraints, defaults or indexes. The table created will not have a clustered index.

Alternatively you could:

INSERT INTO DestinationDB..MyDestinationTable 
SELECT * FROM SourceDB..MySourceTable

If your destination table exists and is empty.

I usually construct custom objects in these loops, and then add these objects to an array that I can easily manipulate, sort, export to CSV, etc.:

# Construct an out-array to use for data export
$OutArray = @()

# The computer loop you already have
foreach ($server in $serverlist)
    {
        # Construct an object
        $myobj = "" | Select "computer", "Speed", "Regcheck"

        # Fill the object
        $myobj.computer = $computer
        $myobj.speed = $speed
        $myobj.regcheck = $regcheck

        # Add the object to the out-array
        $outarray += $myobj

        # Wipe the object just to be sure
        $myobj = $null
    }

# After the loop, export the array to CSV
$outarray | export-csv "somefile.csv"

I think that you are looking for something like this:

   function rightclick() {
    var rightclick;
    var e = window.event;
    if (e.which) rightclick = (e.which == 3);
    else if (e.button) rightclick = (e.button == 2);
    alert(rightclick); // true or false, you can trap right click here by if comparison
}

(http://www.quirksmode.org/js/events_properties.html)

And then use the onmousedown even with the function rightclick() (if you want to use it globally on whole page you can do this <body onmousedown=rightclick(); >

This is my android:layout_height=50% activity:

If you want to use scrollWidth to get the "REAL" CONTENT WIDTH/HEIGHT (as content can be BIGGER than the css-defined width/height-Box) the scrollWidth/Height is very UNRELIABLE as some browser seem to "MOVE" the paddingRIGHT & paddingBOTTOM if the content is to big. They then place the paddings at the RIGHT/BOTTOM of the "too broad/high content" (see picture below).

==> Therefore to get the REAL CONTENT WIDTH in some browsers you have to substract BOTH paddings from the scrollwidth and in some browsers you only have to substract the LEFT Padding.

I found a solution for this and wanted to add this as a comment, but was not allowed. So I took the picture and made it a bit clearer in the regard of the "moved paddings" and the "unreliable scrollWidth". In the BLUE AREA you find my solution on how to get the "REAL" CONTENT WIDTH!

Hope this helps to make things even clearer!

Now we could also use:

if (Attachment != null  && Attachment.Any())

Any() is often easier to understand in a glance for the developer than checking Length() > 0. Also has very little difference with processing speed.

If You want to check only when scroll ended, in Vanilla JS, You can come up with a solution like this:

Super Super compact

var t
window.onresize = () => { clearTimeout(t) t = setTimeout(() => { resEnded() }, 500) }
function resEnded() { console.log('ended') }

All 3 possible combinations together (ES6)

var t
window.onresize = () => {
    resizing(this, this.innerWidth, this.innerHeight) //1
    if (typeof t == 'undefined') resStarted() //2
    clearTimeout(t); t = setTimeout(() => { t = undefined; resEnded() }, 500) //3
}

function resizing(target, w, h) {
    console.log(`Youre resizing: width ${w} height ${h}`)
}    
function resStarted() { 
    console.log('Resize Started') 
}
function resEnded() { 
    console.log('Resize Ended') 
}

Some might encounter this error either locally or on the server:

syntax error var data = new google.visualization.DataTable(<?=$jsonTable?>);

This means that their environment does not support short tags the solution is to use this instead:

<?php echo $jsonTable; ?>

And everything should work fine!

Sometimes no matter what you do or follow whole internet posts. Try on the MIMETYPES of applicationhost.config of the server.

Because the file you source ends lines with carriage returns, the contents of $testVar are likely to look like this:

$ printf '%q\n' "$testVar"
$'value123\r'

(The first line's $ is the shell prompt; the second line's $ is from the %q formatting string, indicating $'' quoting.)

To get rid of the carriage return, you can use shell parameter expansion and ANSI-C quoting (requires Bash):

testVar=${testVar//$'\r'}

Which should result in

$ printf '%q\n' "$testVar"
value123

Color.parseHexColor("17ee27") did not work for me, instead Color.parseColor("17ee27") worked perfectly.

I use $arr = array_merge($arr); to rebase an array. Simple and straightforward.

Here is a more general generator function that skips any number of items from the beginning and end of an iterable:

def skip(iterable, at_start=0, at_end=0):
    it = iter(iterable)
    for x in itertools.islice(it, at_start):
        pass
    queue = collections.deque(itertools.islice(it, at_end))
    for x in it:
        queue.append(x)
        yield queue.popleft()

Example usage:

To get the "pseudo class", you can get the constructor function, by

obj.constructor

assuming the constructor is set correctly when you do the inheritance -- which is by something like:

Dog.prototype = new Animal();
Dog.prototype.constructor = Dog;

and these two lines, together with:

var woofie = new Dog()

will make woofie.constructor point to Dog. Note that Dog is a constructor function, and is a Function object. But you can do if (woofie.constructor === Dog) { ... }.

If you want to get the class name as a string, I found the following working well:

http://blog.magnetiq.com/post/514962277/finding-out-class-names-of-javascript-objects

function getObjectClass(obj) {
    if (obj && obj.constructor && obj.constructor.toString) {
        var arr = obj.constructor.toString().match(
            /function\s*(\w+)/);

        if (arr && arr.length == 2) {
            return arr[1];
        }
    }

    return undefined;
}

It gets to the constructor function, converts it to string, and extracts the name of the constructor function.

Note that obj.constructor.name could have worked well, but it is not standard. It is on Chrome and Firefox, but not on IE, including IE 9 or IE 10 RTM.

have a look at example 3 from http://www.php.net/manual/en/language.oop5.basic.php

$className = 'Foo';
$instance = new $className(); // Foo()

Adding the following lines at the bottom of your batch file will grab everything just as displayed inside the CMD window and export into a text file:

powershell -c "$wshell = New-Object -ComObject wscript.shell; $wshell.SendKeys('^a')
powershell -c "$wshell = New-Object -ComObject wscript.shell; $wshell.SendKeys('^c')
powershell Get-Clipboard > MyLog.txt

It basically performs a select all -> copy into clipboard -> paste into text file.

Try this library:

https://github.com/avast/android-styled-dialogs

It's based on DialogFragments instead of AlertDialogs (like the one from @afollestad). The main advantage: Dialogs don't dismiss after rotation and callbacks still work.

The Binder transaction buffer has a limited fixed size, currently 1Mb, which is shared by all transactions in progress for the process. Consequently this exception can be thrown when there are many transactions in progress even when most of the individual transactions are of moderate size.

I have employed a slightly different technique in my aspnet MVC 4 site:

_ViewStart.cshtml:

@using System.Web.Caching
@using System.Web.Hosting
@{
    Layout = "~/Views/Shared/_Layout.cshtml";
    PageData.Add("scriptFormat", string.Format("<script src=\"{{0}}?_={0}\"></script>", GetDeployTicks()));
}

@functions
{

    private static string GetDeployTicks()
    {
        const string cacheKey = "DeployTicks";
        var returnValue = HttpRuntime.Cache[cacheKey] as string;
        if (null == returnValue)
        {
            var absolute = HostingEnvironment.MapPath("~/Web.config");
            returnValue = File.GetLastWriteTime(absolute).Ticks.ToString();
            HttpRuntime.Cache.Insert(cacheKey, returnValue, new CacheDependency(absolute));
        }
        return returnValue;
    }
}

Then in the actual views:

 @Scripts.RenderFormat(PageData["scriptFormat"], "~/Scripts/Search/javascriptFile.min.js")

Use Subscript Generating Functions.
http://www.postgresql.org/docs/current/static/functions-srf.html#FUNCTIONS-SRF-SUBSCRIPTS

For example:

SELECT 
  id
  , elements[i] AS elem
  , i AS nr
FROM
  ( SELECT 
      id
      , elements
      , generate_subscripts(elements, 1) AS i
    FROM
      ( SELECT
          id
          , string_to_array(elements, ',') AS elements
        FROM
          myTable
      ) AS foo
  ) bar
;

More simply:

SELECT
  id
  , unnest(elements) AS elem
  , generate_subscripts(elements, 1) AS nr
FROM
  ( SELECT
      id
      , string_to_array(elements, ',') AS elements
    FROM
      myTable
  ) AS foo
;

The "nav nav-list" class of Twiter Bootstrap 2.0 is handy for building a side bar.

You can see a lot of documentation at http://www.w3resource.com/twitter-bootstrap/nav-tabs-and-pills-tutorial.php

Use Viewbag is wrong for sending list to view.You should using Viewmodel in this case. like this:

Send Country list and City list and Other list you need to show in View:

HomeController Code:

[HttpGet]
        public ActionResult NewAgahi() // New Advertising
        {
            //--------------------------------------------------------
            // ??????? ?? ?????? ???? ????? ??? ??? ?? ???
            Country_Repository blCountry = new Country_Repository();
            Ostan_Repository blOstan = new Ostan_Repository();
            City_Repository blCity = new City_Repository();
            Mahale_Repository blMahale = new Mahale_Repository();
            Agahi_Repository blAgahi = new Agahi_Repository();

            var vm = new NewAgahi_ViewModel();
            vm.Country = blCountry.Select();
            vm.Ostan = blOstan.Select();
            vm.City = blCity.Select();
            vm.Mahale = blMahale.Select();
            //vm.Agahi = blAgahi.Select();

            return View(vm);
        }

        [ValidateAntiForgeryToken]
        [HttpPost]
        public ActionResult NewAgahi(Agahi agahi)
        {

            if (ModelState.IsValid == true)
            {
                Agahi_Repository blAgahi = new Agahi_Repository();

                agahi.Date = DateTime.Now.Date;
                agahi.UserId = 1048;
                agahi.GroupId = 1;


                if (blAgahi.Add(agahi) == true)

You can use below code

DECLARE @T TABLE ([Month] VARCHAR(20))
INSERT INTO @T
SELECT 'January'
UNION
SELECT 'February'
UNION
SELECT 'March'`

SELECT MONTH('01-' + [Month] + '-2010') As MonthNumeric,[Month] FROM @T
ORDER BY MonthNumeric

The NUMBER type can be specified in different styles:

                Resulting  Resulting  Precision
Specification   Precision  Scale      Check      Comment
-------------------------------------------------------------------------------
NUMBER          NULL       NULL       NO         'maximum range and precision',
                                                 values are stored 'as given'
NUMBER(P, S)    P          S          YES        Error code: ORA-01438
NUMBER(P)       P          0          YES        Error code: ORA-01438
NUMBER(*, S)    38         S          NO

Where the precision is the total number of digits and scale is the number of digits right or left (negative scale) of the decimal point.

Oracle specifies ORA-01438 as

value larger than specified precision allowed for this column

As noted in the table, this integrity check is only active if the precision is explicitly specified. Otherwise Oracle silently rounds the inserted or updated value using some unspecified method.

I believe you can do this using a Unicode encoding, but I doubt this is what you really want.

The == is the unicode value 2A76 so I belive you can do this:

char c = '\u2A76';

I can't test this at the moment but I'd be interested to know if that works for you.

You will need to dig around for the others. Here is a unicode table if you want to look:

http://www.tamasoft.co.jp/en/general-info/unicode.html

text_file = open("Output.txt", "w")
text_file.write("Purchase Amount: %s" % TotalAmount)
text_file.close()

If you use a context manager, the file is closed automatically for you

with open("Output.txt", "w") as text_file:
    text_file.write("Purchase Amount: %s" % TotalAmount)

If you're using Python2.6 or higher, it's preferred to use str.format()

with open("Output.txt", "w") as text_file:
    text_file.write("Purchase Amount: {0}".format(TotalAmount))

For python2.7 and higher you can use {} instead of {0}

In Python3, there is an optional file parameter to the print function

with open("Output.txt", "w") as text_file:
    print("Purchase Amount: {}".format(TotalAmount), file=text_file)

Python3.6 introduced f-strings for another alternative

with open("Output.txt", "w") as text_file:
    print(f"Purchase Amount: {TotalAmount}", file=text_file)

If your dictionary is not nested, you could make a frozenset with the dict's items and use hash():

hash(frozenset(my_dict.items()))

This is much less computationally intensive than generating the JSON string or representation of the dictionary.

UPDATE: Please see the comments below, why this approach might not produce a stable result.

You can do like...

If you want to access using ColumnName

Int32 First = Convert.ToInt32(ds.Tables[0].Rows[0]["column4Name"].ToString());
Int32 Second = Convert.ToInt32(ds.Tables[0].Rows[0]["column5Name"].ToString());

OR, if you want to access using Index

Int32 First = Convert.ToInt32(ds.Tables[0].Rows[0][4].ToString());
Int32 Second = Convert.ToInt32(ds.Tables[0].Rows[0][5].ToString());

cp -r ls -A | grep -v "Excluded_File_or_folder" ../$target_location -v

The value for an annotation must be a compile time constant, so there is no simple way of doing what you are trying to do.

See also here: How to supply value to an annotation from a Constant java

It is possible to use some compile time tools (ant, maven?) to config it if the value is known before you try to run the program.

Print datatable rows with column

Here is solution 

DataTable datatableinfo= new DataTable();

// Fill data table 

//datatableinfo=fill by function or get data from database

//Print data table with rows and column


for (int j = 0; j < datatableinfo.Rows.Count; j++)
{
    for (int i = 0; i < datatableinfo.Columns.Count; i++)    
        {    
            Console.Write(datatableinfo.Columns[i].ColumnName + " ");    
            Console.WriteLine(datatableinfo.Rows[j].ItemArray[i]+" "); 
        }
}


Ouput :
ColumnName - row Value
ColumnName - row Value
ColumnName - row Value
ColumnName - row Value

Maybe, something like

for t in threading.enumerate():
    if t.daemon:
        t.join()

In response to Jonathan's answer above, this only seems to work for certain delimiters. For example:

>>> a='Beautiful, is; better*than\nugly'
>>> import re
>>> re.split('; |, |\*|\n',a)
['Beautiful', 'is', 'better', 'than', 'ugly']

>>> b='1999-05-03 10:37:00'
>>> re.split('- :', b)
['1999-05-03 10:37:00']

By putting the delimiters in square brackets it seems to work more effectively.

>>> re.split('[- :]', b)
['1999', '05', '03', '10', '37', '00']

Go to the GitHub page where they are maintain the official repository: https://github.com/spring-projects/eclipse-integration-gradle/blob/master/README.md

Copy the latest release link: http://dist.springsource.com/release/TOOLS/gradle (latest release)

Use this in Eclipse->Help->Install New Software..->Paste the link in "Work With"->press enter->select the names of the extension->click next and agree the license and follow the prompts.

After you have installed just import the project as a grade project and eclipse will take of the rest.

Here's what worked for me, here I'm attaching a file to my EmailController under test. Also take a look at the postman screenshot on how I'm posting the data.

    @WebAppConfiguration
    @RunWith(SpringRunner.class)
    @SpringBootTest(
            classes = EmailControllerBootApplication.class
        )

        @Autowired
        private WebApplicationContext webApplicationContext;

        @Test
        public void testSend() throws Exception{
            String jsonStr = "{\"to\": [\"[email protected]\"],\"subject\": "
                    + "\"CDM - Spring Boot email service with attachment\","
                    + "\"body\": \"Email body will contain  test results, with screenshot\"}";

            Resource fileResource = new ClassPathResource(
                    "screen-shots/HomePage-attachment.png");

            assertNotNull(fileResource);

            MockMultipartFile firstFile = new MockMultipartFile( 
                       "attachments",fileResource.getFilename(),
                        MediaType.MULTIPART_FORM_DATA_VALUE,
                        fileResource.getInputStream());  
                        assertNotNull(firstFile);


            MockMvc mockMvc = MockMvcBuilders.
                  webAppContextSetup(webApplicationContext).build();

            mockMvc.perform(MockMvcRequestBuilders
                   .multipart("/api/v1/email/send")
                    .file(firstFile)
                    .param("data", jsonStr))
                    .andExpect(status().is(200));
            }
        }

The T doesn't really stand for anything. It is just the separator that the ISO 8601 combined date-time format requires. You can read it as an abbreviation for Time.

The Z stands for the Zero timezone, as it is offset by 0 from the Coordinated Universal Time (UTC).

Both characters are just static letters in the format, which is why they are not documented by the datetime.strftime() method. You could have used Q or M or Monty Python and the method would have returned them unchanged as well; the method only looks for patterns starting with % to replace those with information from the datetime object.

From your code it becomes apparent that you use POCO. Having another key is unnecessary: you can add an index as suggested by juFo.
If you use Fluent API instead of attributing UserName property your column annotation should look like this:

this.Property(p => p.UserName)
    .HasColumnAnnotation("Index", new IndexAnnotation(new[] { 
        new IndexAttribute("Index") { IsUnique = true } 
    }
));

This will create the following SQL script:

CREATE UNIQUE NONCLUSTERED INDEX [Index] ON [dbo].[Users]
(
    [UserName] ASC
)
WITH (
    PAD_INDEX = OFF, 
    STATISTICS_NORECOMPUTE = OFF, 
    SORT_IN_TEMPDB = OFF, 
    IGNORE_DUP_KEY = OFF, 
    DROP_EXISTING = OFF, 
    ONLINE = OFF, 
    ALLOW_ROW_LOCKS = ON, 
    ALLOW_PAGE_LOCKS = ON
) ON [PRIMARY]

If you attempt to insert multiple Users having the same UserName you'll get a DbUpdateException with the following message:

Cannot insert duplicate key row in object 'dbo.Users' with unique index 'Index'. 
The duplicate key value is (...).
The statement has been terminated.

Again, column annotations are not available in Entity Framework prior to version 6.1.

1. Prerequisite: You must know how to use decorators and specially with wraps. This comment explains it a bit clear or this link also explains it pretty well.

2. Whenever we use For eg: @wraps followed by our own wrapper function. As per the details given in this link , it says that

functools.wraps is convenience function for invoking update_wrapper() as a function decorator, when defining a wrapper function.

It is equivalent to partial(update_wrapper, wrapped=wrapped, assigned=assigned, updated=updated).

So @wraps decorator actually gives a call to functools.partial(func[,*args][, **keywords]).

The functools.partial() definition says that

The partial() is used for partial function application which “freezes” some portion of a function’s arguments and/or keywords resulting in a new object with a simplified signature. For example, partial() can be used to create a callable that behaves like the int() function where the base argument defaults to two:

>>> from functools import partial
>>> basetwo = partial(int, base=2)
>>> basetwo.__doc__ = 'Convert base 2 string to an int.'
>>> basetwo('10010')
18

Which brings me to the conclusion that, @wraps gives a call to partial() and it passes your wrapper function as a parameter to it. The partial() in the end returns the simplified version i.e the object of what's inside the wrapper function and not the wrapper function itself.

The stable of APC is having option to clear a cache in its interface itself. To clear those entries you must login to apc interface.

APC is having option to set username and password in apc.php file.

As I want to handle both IPv4 and IPv6, I am using VARBINARY(16) and the following SQL CLR functions to convert the text IP address presentation to bytes and the reverse:

[SqlFunction(DataAccess = DataAccessKind.None, IsDeterministic = true)]
public static SqlBytes GetIPAddressBytesFromString (SqlString value)
{
    IPAddress IP;

    if (IPAddress.TryParse(value.Value, out IP))
    {
        return new SqlBytes(IP.GetAddressBytes());
    }
    else
    {
        return new SqlBytes();
    }
}


[SqlFunction(DataAccess = DataAccessKind.None, IsDeterministic = true)]
public static SqlString GetIPAddressStringFromBytes(SqlBytes value)
{
    string output;

    if (value.IsNull)
    {
        output = "";
    }
    else
    {
        IPAddress IP = new IPAddress(value.Value);
        output = IP.ToString();
    }

    return new SqlString(output);
}

Unfortunately to be able to use the extension modules provided by others you'll be forced to use the official compiler to compile Python. These are:

• Visual Studio 2008 for Python 2.7. See: https://docs.python.org/2.7/using/windows.html#compiling-python-on-windows

• Visual Studio 2010 for Python 3.4. See: https://docs.python.org/3.4/using/windows.html#compiling-python-on-windows

Alternatively, you can use MinGw to compile extensions in a way that won't depend on others.

See: https://docs.python.org/2/install/#gnu-c-cygwin-MinGW or https://docs.python.org/3.4/install/#gnu-c-cygwin-mingw

This allows you to have one compiler to build your extensions for both versions of Python, Python 2.x and Python 3.x.

You can use DocToc to generate the table of contents from command line with:

@RequestParam annotation used for accessing the query parameter values from the request. Look at the following request URL:

http://localhost:8080/springmvc/hello/101?param1=10&param2=20

In the above URL request, the values for param1 and param2 can be accessed as below:

public String getDetails(
    @RequestParam(value="param1", required=true) String param1,
        @RequestParam(value="param2", required=false) String param2){
...
}

The following are the list of parameters supported by the @RequestParam annotation:

• defaultValue – This is the default value as a fallback mechanism if request is not having the value or it is empty.
• name – Name of the parameter to bind
• required – Whether the parameter is mandatory or not. If it is true, failing to send that parameter will fail.
• value – This is an alias for the name attribute

@PathVariable

@PathVariable identifies the pattern that is used in the URI for the incoming request. Let’s look at the below request URL:

http://localhost:8080/springmvc/hello/101?param1=10&param2=20

The above URL request can be written in your Spring MVC as below:

@RequestMapping("/hello/{id}")    public String getDetails(@PathVariable(value="id") String id,
    @RequestParam(value="param1", required=true) String param1,
    @RequestParam(value="param2", required=false) String param2){
.......
}

The @PathVariable annotation has only one attribute value for binding the request URI template. It is allowed to use the multiple @PathVariable annotation in the single method. But, ensure that no more than one method has the same pattern.

Also there is one more interesting annotation: @MatrixVariable

http://localhost:8080/spring_3_2/matrixvars/stocks;BT.A=276.70,+10.40,+3.91;AZN=236.00,+103.00,+3.29;SBRY=375.50,+7.60,+2.07

And the Controller method for it

 @RequestMapping(value = "/{stocks}", method = RequestMethod.GET)
  public String showPortfolioValues(@MatrixVariable Map<String, List<String>> matrixVars, Model model) {

    logger.info("Storing {} Values which are: {}", new Object[] { matrixVars.size(), matrixVars });

    List<List<String>> outlist = map2List(matrixVars);
    model.addAttribute("stocks", outlist);

    return "stocks";
  }

But you must enable:

<mvc:annotation-driven enableMatrixVariables="true" >

It will look like this

You can use the substring method of JavaScript string objects:

s = s.substring(0, s.length - 4)

It unconditionally removes the last four characters from string s.

However, if you want to conditionally remove the last four characters, only if they are exactly _bar:

var re = /_bar$/;
s.replace(re, "");

TextView does not support setMargins. Android docs say:

Even though a view can define a padding, it does not provide any support for margins. However, view groups provide such a support. Refer to ViewGroup and ViewGroup.MarginLayoutParams for further information.

See the official documentation (http://docs.oracle.com/cd/B19306_01/server.102/b14200/sql_elements001.htm#i54330)

Variable-length character string having maximum length size bytes or characters. Maximum size is 4000 bytes or characters, and minimum is 1 byte or 1 character. You must specify size for VARCHAR2. BYTE indicates that the column will have byte length semantics; CHAR indicates that the column will have character semantics.

But in Oracle Databast 12c maybe 32767 (http://docs.oracle.com/database/121/SQLRF/sql_elements001.htm#SQLRF30020)

Variable-length character string having maximum length size bytes or characters. You must specify size for VARCHAR2. Minimum size is 1 byte or 1 character. Maximum size is: 32767 bytes or characters if MAX_STRING_SIZE = EXTENDED 4000 bytes or characters if MAX_STRING_SIZE = STANDARD

How about this?

   Map properties = new Properties();
   Map<String, String> map = new HashMap<String, String>(properties);

Will cause a warning, but works without iterations.

Getting the Text of ComboBox when the item is changed

     self.ui.comboBox.activated.connect(self.pass_Net_Adap)

  def pass_Net_Adap(self):
      print str(self.ui.comboBox.currentText())

1) First Insert JS file path in an index.html file :

<script src="assets/video.js" type="text/javascript"></script>

2) Import JS file and declare the variable in component.ts :

• import './../../../assets/video.js';

• declare var RunPlayer: any;

  NOTE: Variable name should be same as the name of a function in js file

3) Call the js method in the component

ngAfterViewInit(){

    setTimeout(() => {
        new RunPlayer();

Take a look at this Github issue:

https://github.com/facebook/react-native/issues/231

They are trying to require non-JSON files, in particular JSON. There is no method of doing this right now, so you either have to use AsyncStorage as @CocoOS mentioned, or you could write a small native module to do what you need to do.

I was looking for a simple solution without having to install additional stuff and compatible with common hostings that allow SSH access.

I've ended up with this setup for my chat server:

-rwxr-xr-x  1 crazypoems psacln   309 ene 30 14:01 checkChatServerRunning.sh
-rw-r--r--  1 crazypoems psacln  3018 ene 30 13:12 class.chathandler.php
-rw-r--r--  1 crazypoems psacln    29 ene 30 14:05 cron.log
-rw-r--r--  1 crazypoems psacln  2560 ene 29 08:04 index.php
-rw-r--r--  1 crazypoems psacln  2672 ene 30 13:29 php-socket.php
-rwxr-xr-x  1 crazypoems psacln   310 ene 30 14:04 restartChatServer.sh
-rwxr-xr-x  1 crazypoems psacln   122 ene 30 13:28 startChatServer.sh
-rwxr-xr-x  1 crazypoems psacln   224 ene 30 13:56 stopChatServer.sh

And the scripts:

startChatServer.sh

#!/bin/bash
nohup /opt/plesk/php/5.6/bin/php -q /var/www/vhosts/crazypoems.org/httpdocs/chat/php-socket.php > /dev/null &

stopChatServer.sh

#!/bin/bash
PID=`ps -eaf | grep '/var/www/vhosts/crazypoems.org/httpdocs/chat/php-socket.php' | grep -v grep | awk '{print $2}'`
if [[ "" !=  "$PID" ]]; then
  echo "killing $PID"
  kill -9 $PID
else
  echo "not running"
fi

restartChatServer.sh

#!/bin/bash
PID=`ps -eaf | grep '/var/www/vhosts/crazypoems.org/httpdocs/chat/php-socket.php' | grep -v grep | awk '{print $2}'`
if [[ "" !=  "$PID" ]]; then
  echo "killing $PID"
  kill -9 $PID
else
  echo "not running"
fi
echo "Starting again"
/var/www/vhosts/crazypoems.org/httpdocs/chat/startChatServer.sh

And last but not least, I have put this last script on a cron job, to check if the "chat server is running", and if not, to start it:

Cron job every minute

-bash-4.1$ crontab -l
*       *       *       *       * /var/www/vhosts/crazypoems.org/httpdocs/chat/checkChatServerRunning.sh > /var/www/vhosts/crazypoems.org/httpdocs/chat/cron.log

checkChatServerRunning.sh

#!/bin/bash
PID=`ps -eaf | grep '/var/www/vhosts/crazypoems.org/httpdocs/chat/php-socket.php' | grep -v grep | awk '{print $2}'`
if [[ "" !=  "$PID" ]]; then
  echo "Chat server running on $PID"
else
  echo "Not running, going to start it"
  /var/www/vhosts/crazypoems.org/httpdocs/chat/startChatServer.sh
fi

So with this setup:

• I manually can control the service with the scripts when needed (eg: maintenance)
• The cron job will start the server on reboot, or on crash

Some devices don't provide the orientationchange event, but do fire the window's resize event:

// Listen for resize changes
window.addEventListener("resize", function() {
    // Get screen size (inner/outerWidth, inner/outerHeight)

}, false);

A bit less obvious than the orientationchange event, but works very well. Please check here

Have a look at this page.

you can try globally adding the flag using: export CXXFLAGS="$CXXFLAGS -fPIC"

this is what you need, the child combinator:

    select>option:hover
    {
        color: #1B517E;
        cursor: pointer;
    }

Try it, works perfect.

Here's the reference: http://www.w3schools.com/css/css_combinators.asp

What you need is called attribute selector. An example, using your html structure, is the following:

div[class^="tocolor-"], div[class*=" tocolor-"] {
    color:red 
}

In the place of div you can add any element or remove it altogether, and in the place of class you can add any attribute of the specified element.

[class^="tocolor-"] — starts with "tocolor-".
[class*=" tocolor-"] — contains the substring "tocolor-" occurring directly after a space character.

Demo: http://jsfiddle.net/K3693/1/

More information on CSS attribute selectors, you can find here and here. And from MDN Docs MDN Docs

All of the applications delivered with Android (Calendar, Contacts, Email, etc) are all open-source, but not part of the SDK. The source for those projects is here: https://android.googlesource.com/ (look at /platform/packages/apps).

Worked without error and all lines were successfully read in.

Another way to do is to use the str.rpartition(sep) method.

For example:

filename = '/home/user/somefile.txt'
(prefix, sep, suffix) = filename.rpartition('.')

new_filename = prefix + '.jpg'

print new_filename

The problem you face is that you try to assign the return of imshow (which is an matplotlib.image.AxesImage to an existing axes object.

The correct way of plotting image data to the different axes in axarr would be

f, axarr = plt.subplots(2,2)
axarr[0,0].imshow(image_datas[0])
axarr[0,1].imshow(image_datas[1])
axarr[1,0].imshow(image_datas[2])
axarr[1,1].imshow(image_datas[3])

The concept is the same for all subplots, and in most cases the axes instance provide the same methods than the pyplot (plt) interface. E.g. if ax is one of your subplot axes, for plotting a normal line plot you'd use ax.plot(..) instead of plt.plot(). This can actually be found exactly in the source from the page you link to.

Note that the above solutions will not tell you if your installation is correct only if your install.exe is correct (you can trust it to produce a correct install.)

You would need MD5 sums for each file/folder to test if the installed code has been messed with after the install completed.

WinMerg is useful to compare two installs (on two different machines perhaps) to see if one has been changed or why one is broken.

When using webview as a subview somewhere in scrollview, you can set height constraint to some constant value and later make outlet from it and use it like:

- (void)webViewDidFinishLoad:(UIWebView *)webView {
    webView.scrollView.scrollEnabled = NO;
    _webViewHeight.constant = webView.scrollView.contentSize.height;
}

One correct way to get selected value would be

var selected_value = $('#fruit_name').val()

And then you should do

if(selected_value) { ... }

Spinlock and Mutex synchronization mechanisms are very common today to be seen.

Let's think about Spinlock first.

Basically it is a busy waiting action, which means that we have to wait for a specified lock is released before we can proceed with the next action. Conceptually very simple, while implementing it is not on the case. For example: If the lock has not been released then the thread was swap-out and get into the sleep state, should do we deal with it? How to deal with synchronization locks when two threads simultaneously request access ?

Generally, the most intuitive idea is dealing with synchronization via a variable to protect the critical section. The concept of Mutex is similar, but they are still different. Focus on: CPU utilization. Spinlock consumes CPU time to wait for do the action, and therefore, we can sum up the difference between the two:

In homogeneous multi-core environments, if the time spend on critical section is small than use Spinlock, because we can reduce the context switch time. (Single-core comparison is not important, because some systems implementation Spinlock in the middle of the switch)

In Windows, using Spinlock will upgrade the thread to DISPATCH_LEVEL, which in some cases may be not allowed, so this time we had to use a Mutex (APC_LEVEL).

The angular new version does not support .map you have to install this through cmd npm install --save rxjs-compat via this you can enjoy with old technique . note: don't forget to import these lines.

import { Observable, Subject } from 'rxjs';
import 'rxjs/add/operator/map';
import 'rxjs/add/operator/catch';

I think Buu's digest cycle watch is genius. Thanks for sharing. As others have noted $interval also causes the digest cycle to run. We could for the purpose of auto logging the user out use setInterval which will not cause a digest loop.

app.run(function($rootScope) {
    var lastDigestRun = new Date();
    setInterval(function () {
        var now = Date.now();
        if (now - lastDigestRun > 10 * 60 * 1000) {
          //logout
        }
    }, 60 * 1000);

    $rootScope.$watch(function() {
        lastDigestRun = new Date();
    });
});

If you are a linux user Update node to a later version by running

sudo apt update

 sudo apt install build-essential checkinstall libssl-dev

curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.35.1/install.sh | bash

nvm --version

nvm ls

nvm ls-remote

nvm install [version.number]

this should solve your problem

@interface UIDevice (Screen)
typedef enum
{
    iPhone          = 1 << 1,
    iPhoneRetina    = 1 << 2,
    iPhone5         = 1 << 3,
    iPad            = 1 << 4,
    iPadRetina      = 1 << 5

} DeviceType;

+ (DeviceType)deviceType;
@end

.m

#import "UIDevice+Screen.h"
@implementation UIDevice (Screen)

+ (DeviceType)deviceType
{
    DeviceType thisDevice = 0;
    if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone)
    {
        thisDevice |= iPhone;
        if ([[UIScreen mainScreen] respondsToSelector: @selector(scale)])
        {
            thisDevice |= iPhoneRetina;
            if ([[UIScreen mainScreen] bounds].size.height == 568)
                thisDevice |= iPhone5;
        }
    }
    else
    {
        thisDevice |= iPad;
        if ([[UIScreen mainScreen] respondsToSelector: @selector(scale)])
            thisDevice |= iPadRetina;
    }
    return thisDevice;
}

@end

This way, if you want to detect whether it is just an iPhone or iPad (regardless of screen-size), you just use:

if ([UIDevice deviceType] & iPhone) 

or

if ([UIDevice deviceType] & iPad)

If you want to detect just the iPhone 5, you can use

if ([UIDevice deviceType] & iPhone5)

As opposed to Malcoms answer where you would need to check just to figure out if it's an iPhone,

if ([UIDevice currentResolution] == UIDevice_iPhoneHiRes || 
    [UIDevice currentResolution] == UIDevice_iPhoneStandardRes || 
    [UIDevice currentResolution] == UIDevice_iPhoneTallerHiRes)`

Neither way has a major advantage over one another, it is just a personal preference.

I believe you want to use CHARINDEX. You can read about it here.

With the Python library pandas, you can easily create column names and infer data types from a csv file.

from sqlalchemy import create_engine
import pandas as pd

engine = create_engine('postgresql://user:pass@localhost/db_name')
df = pd.read_csv('/path/to/csv_file')
df.to_sql('pandas_db', engine)

The if_exists parameter can be set to replace or append to an existing table, e.g. df.to_sql('pandas_db', engine, if_exists='replace'). This works for additional input file types as well, docs here and here.

s1 = "hello python world , i'm a beginner "
s2 = "world"

print s1[s1.index(s2) + len(s2):]

If you want to deal with the case where s2 is not present in s1, then use s1.find(s2) as opposed to index. If the return value of that call is -1, then s2 is not in s1.

I was faces this issue but after change object into str, problem solved. str(fname).isalpha():

setState takes new state and optional callback function which is called after the state has been updated.

this.setState(
  {newState: 'whatever'},
  () => {/*do something after the state has been updated*/}
)

Here are 535 ways to reload a page using javascript, very cool:

Here are the first 20:

location = location
location = location.href
location = window.location
location = self.location
location = window.location.href
location = self.location.href
location = location['href']
location = window['location']
location = window['location'].href
location = window['location']['href']
location = window.location['href']
location = self['location']
location = self['location'].href
location = self['location']['href']
location = self.location['href']
location.assign(location)
location.replace(location)
window.location.assign(location)
window.location.replace(location)
self.location.assign(location)

and the last 10:

self['location']['replace'](self.location['href'])
location.reload()
location['reload']()
window.location.reload()
window['location'].reload()
window.location['reload']()
window['location']['reload']()
self.location.reload()
self['location'].reload()
self.location['reload']()
self['location']['reload']()

If you want to use the primitive wrapper classes, this will work, but all java types are signed by default.

public static void main(String[] args) {
    Integer i=5;
    Byte b = Byte.valueOf(i+""); //converts i to String and calls Byte.valueOf()
    System.out.println(b);
    System.out.println(Integer.valueOf(b));
}

I had to play with the widths of my main containers:

html {
  @media only screen and (orientation: portrait) and (max-width: 555px) {
    transform: rotate(90deg);
    width: calc(155%);
    .content {
      width: calc(155%);
    }
  }
}

It's an old question but it worth to mention that in Angular 1.4 $httpParamSerializer is added and when using $http.post, if we use $httpParamSerializer(params) to pass the parameters, everything works like a regular post request and no JSON deserializing is needed on server side.

https://docs.angularjs.org/api/ng/service/$httpParamSerializer

This snippet could help you with it in a few lines of jQuery 1.9+: http://jsfiddle.net/4MBUG/2/

$('input[type=button]').on('click', function() {
    var cursorPos = $('#text').prop('selectionStart');
    var v = $('#text').val();
    var textBefore = v.substring(0,  cursorPos);
    var textAfter  = v.substring(cursorPos, v.length);

    $('#text').val(textBefore + $(this).val() + textAfter);
});

I think the best way to work with dates between C# and SQL is, of course, use parametrized queries, and always work with DateTime objects on C# and the ToString() formating options it provides.

You better execute set datetime <format> (here you have the set dateformat explanation on MSDN) before working with dates on SQL Server so you don't get in trouble, like for example set datetime ymd. You only need to do it once per connection because it mantains the format while open, so a good practice would be to do it just after openning the connection to the database.
Then, you can always work with 'yyyy-MM-dd HH:mm:ss:ffff' formats.

To pass the DateTime object to your parametrized query you can use DateTime.ToString('yyyy-MM-dd HH:mm:ss:ffff').

For parsing weird formatted dates on C# you can use DateTime.ParseExact() method, where you have the option to specify exactly what the input format is: DateTime.ParseExact(<some date string>, 'dd/MM-yyyy',CultureInfo.InvariantCulture). Here you have the DateTime.ParseExact() explanation on MSDN)

This could be achieve with the below mentioned psuedo code approach

Import os import requests Data = os.execute(curl URL) R= Data.json()

$(document).ready(function(){
    var response;
    $.validator.addMethod(
        "uniqueUserName", 
        function(value, element) {
            $.ajax({
                type: "POST",
                url: "http://"+location.host+"/checkUser.php",
                data: "checkUsername="+value,
                dataType:"html",
                success: function(msg)
                {
                    //If username exists, set response to true
                    response = ( msg == 'true' ) ? true : false;
                }
             });
            return response;
        },
        "Username is Already Taken"
    );

    $("#regFormPart1").validate({
        username: {
            required: true,
            minlength: 8,
            uniqueUserName: true
        },
        messages: {
            username: {
                required: "Username is required",
                minlength: "Username must be at least 8 characters",
                uniqueUserName: "This Username is taken already"
            }
        }
    });
});

Like @Gabi Purcaru mentions above, the proper way to rename and move the file is to use move_uploaded_file(). It performs some safety checks to prevent security vulnerabilities and other exploits. You'll need to sanitize the value of $_FILES['file']['name'] if you want to use it or an extension derived from it. Use pathinfo($_FILES['file']['name'], PATHINFO_EXTENSION) to safely get the extension.

You wont be able to access a local resource from your aspx page (web server). Have you tried a relative path from your aspx page to your css file like so...

<link rel="stylesheet" media="all" href="/CSS/Style.css" type="text/css" />

The above assumes that you have a folder called CSS in the root of your website like this:

http://www.website.com/CSS/Style.css

    SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
    Calendar cal = Calendar.getInstance();
    System.out.println("time => " + dateFormat.format(cal.getTime()));

    String time_str = dateFormat.format(cal.getTime());

    String[] s = time_str.split(" ");

    for (int i = 0; i < s.length; i++) {
         System.out.println("date  => " + s[i]);
    }

    int year_sys = Integer.parseInt(s[0].split("/")[0]);
    int month_sys = Integer.parseInt(s[0].split("/")[1]);
    int day_sys = Integer.parseInt(s[0].split("/")[2]);

    int hour_sys = Integer.parseInt(s[1].split(":")[0]);
    int min_sys = Integer.parseInt(s[1].split(":")[1]);

    System.out.println("year_sys  => " + year_sys);
    System.out.println("month_sys  => " + month_sys);
    System.out.println("day_sys  => " + day_sys);

    System.out.println("hour_sys  => " + hour_sys);
    System.out.println("min_sys  => " + min_sys);

<<= is like +=, but for a left shift. x <<= 1 means x = x << 1. That's why 90 >>= angle doesn't parse. And, like others have said, Java doesn't have an elegant syntax for checking if a number is an an interval, so you have to do it the long way. It also can't do if (x == 0 || 1), and you're stuck writing it out the long way.

myString.Length; //will get you your result
//alternatively, if you only want the count of letters:
myString.Count(char.IsLetter);
//however, if you want to display the words as ***_***** (where _ is a space)
//you can also use this:
//small note: that will fail with a repeated word, so check your repeats!
myString.Split(' ').ToDictionary(n => n, n => n.Length);
//or if you just want the strings and get the counts later:
myString.Split(' ');
//will not fail with repeats
//and neither will this, which will also get you the counts:
myString.Split(' ').Select(n => new KeyValuePair<string, int>(n, n.Length));

Important:
Read the note at the end.

Quick answer :
Use to_string(). (available since c++11)
example :

#include <iostream>   
#include <string>  

using namespace std;
int main ()
{
    string pi = "pi is " + to_string(3.1415926);
    cout<< "pi = "<< pi << endl;

  return 0;
}

run it yourself : http://ideone.com/7ejfaU
These are available as well :

string to_string (int val);
string to_string (long val);
string to_string (long long val);
string to_string (unsigned val);
string to_string (unsigned long val);
string to_string (unsigned long long val);
string to_string (float val);
string to_string (double val);
string to_string (long double val);

Important Note:
As @Michael Konecný rightfully pointed out, using to_string() is risky at best that is its very likely to cause unexpected results.
From http://en.cppreference.com/w/cpp/string/basic_string/to_string :

With floating point types std::to_string may yield unexpected results as the number of significant digits in the returned string can be zero, see the example.
The return value may differ significantly from what std::cout prints by default, see the example. std::to_string relies on the current locale for formatting purposes, and therefore concurrent calls to std::to_string from multiple threads may result in partial serialization of calls. C++17 provides std::to_chars as a higher-performance locale-independent alternative.

The best way would be to use stringstream as others such as @dcp demonstrated in his answer.:

This issue is demonstrated in the following example :
run the example yourself : https://www.jdoodle.com/embed/v0/T4k

#include <iostream>
#include <sstream>
#include <string>

template < typename Type > std::string to_str (const Type & t)
{
  std::ostringstream os;
  os << t;
  return os.str ();
}

int main ()
{

  // more info : https://en.cppreference.com/w/cpp/string/basic_string/to_string
  double    f = 23.43;
  double    f2 = 1e-9;
  double    f3 = 1e40;
  double    f4 = 1e-40;
  double    f5 = 123456789;
  std::string f_str = std::to_string (f);
  std::string f_str2 = std::to_string (f2); // Note: returns "0.000000"
  std::string f_str3 = std::to_string (f3); // Note: Does not return "1e+40".
  std::string f_str4 = std::to_string (f4); // Note: returns "0.000000"
  std::string f_str5 = std::to_string (f5);

  std::cout << "std::cout: " << f << '\n'
    << "to_string: " << f_str << '\n'
    << "ostringstream: " << to_str (f) << "\n\n"
    << "std::cout: " << f2 << '\n'
    << "to_string: " << f_str2 << '\n'
    << "ostringstream: " << to_str (f2) << "\n\n"
    << "std::cout: " << f3 << '\n'
    << "to_string: " << f_str3 << '\n'
    << "ostringstream: " << to_str (f3) << "\n\n"
    << "std::cout: " << f4 << '\n'
    << "to_string: " << f_str4 << '\n'
    << "ostringstream: " << to_str (f4) << "\n\n"
    << "std::cout: " << f5 << '\n'
    << "to_string: " << f_str5 << '\n'
    << "ostringstream: " << to_str (f5) << '\n';

  return 0;
}

output :

std::cout: 23.43
to_string: 23.430000
ostringstream: 23.43

std::cout: 1e-09
to_string: 0.000000
ostringstream: 1e-09

std::cout: 1e+40
to_string: 10000000000000000303786028427003666890752.000000
ostringstream: 1e+40

std::cout: 1e-40
to_string: 0.000000
ostringstream: 1e-40

std::cout: 1.23457e+08
to_string: 123456789.000000
ostringstream: 1.23457e+08 

Other answers are old, could not get a good answer.
Below example is for object literals, helps how both can complement each other, and how it cannot complement each other (therefore difference):

var obj1 = { a: 1,  b: { b1: 1, b2: 'b2value', b3: 'b3value' } };

// overwrite parts of b key
var obj2 = {
      b: {
        ...obj1.b,
        b1: 2
      }
};
var res2 = Object.assign({}, obj1, obj2); // b2,b3 keys still exist
document.write('res2: ', JSON.stringify (res2), '<br>');
// Output:
// res2: {"a":1,"b":{"b1":2,"b2":"b2value","b3":"b3value"}}  // NOTE: b2,b3 still exists

// overwrite whole of b key
var obj3 = {
      b: {
        b1: 2
      }
};
var res3 = Object.assign({}, obj1, obj3); // b2,b3 keys are lost
document.write('res3: ', JSON.stringify (res3), '<br>');
// Output:
  // res3: {"a":1,"b":{"b1":2}}  // NOTE: b2,b3 values are lost

Several more small examples here, also for array & object:
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Spread_syntax

Another thing is - if your keys are very complicated sometimes you need to replace the places of the fields and it helps :

if this dosent work:

foreign key (ISBN, Title) references BookTitle (ISBN, Title)

Then this might work (not for this specific example but in general) :

foreign key (Title,ISBN) references BookTitle (Title,ISBN)

If you're trying to load a DataTable, then leverage the SqlDataAdapter instead:

DataTable dt = new DataTable();

using (SqlConnection c = new SqlConnection(cString))
using (SqlDataAdapter sda = new SqlDataAdapter(sql, c))
{
    sda.SelectCommand.CommandType = CommandType.StoredProcedure;
    sda.SelectCommand.Parameters.AddWithValue("@parm1", val1);
    ...

    sda.Fill(dt);
}

You don't even need to define the columns. Just create the DataTable and Fill it.

Here, cString is your connection string and sql is the stored procedure command.

This not the best way to manage session in react you can use web tokens to encrypt your data that you want save,you can use various number of services available a popular one is JSON web tokens(JWT) with web-tokens you can logout after some time if there no action from the client And after creating the token you can store it in your local storage for ease of access.

jwt.sign({user}, 'secretkey', { expiresIn: '30s' }, (err, token) => {
    res.json({
      token
  });

user object in here is the user data which you want to keep in the session

localStorage.setItem('session',JSON.stringify(token));

In cases where the Oracle solution seems overly convoluted, I create a java class with static methods and then install it as a package in Oracle. This might not be as performant, but you will eventually find other cases (date conversion to milliseconds for example) where you will find the java fallback helpful.

Note that your main arguments are not correct. The standard form should be:

int main(int argc, char *argv[])

or equivalently:

int main(int argc, char **argv)

There are many ways to achieve the conversion. This is one approach:

#include <sstream>

int main(int argc, char *argv[])
{
    if (argc >= 2)
    {
        std::istringstream iss( argv[1] );
        int val;

        if (iss >> val)
        {
            // Conversion successful
        }
    }

    return 0;
}

Include stdlib.h in your header, and then call abort(); in any place you want to exit your program. Like this:

switch(varName)
{
    case 1: 
     blah blah;
    case 2:
     blah blah;
    case 3:
     abort();
}

When the user enters the switch accepts this and give it to the case 3 where you call the abort function. It will exit your screen immediately after hitting enter key.

Here is how you can read the entire file contents, and if done successfully, start a webserver which displays the JPG image in response to every request:

var http = require('http')
var fs = require('fs')

fs.readFile('image.jpg', function(err, data) {
  if (err) throw err // Fail if the file can't be read.
  http.createServer(function(req, res) {
    res.writeHead(200, {'Content-Type': 'image/jpeg'})
    res.end(data) // Send the file data to the browser.
  }).listen(8124)
  console.log('Server running at http://localhost:8124/')
})

Note that the server is launched by the "readFile" callback function and the response header has Content-Type: image/jpeg.

[Edit] You could even embed the image in an HTML page directly by using an <img> with a data URI source. For example:

  res.writeHead(200, {'Content-Type': 'text/html'});
  res.write('<html><body><img src="data:image/jpeg;base64,')
  res.write(Buffer.from(data).toString('base64'));
  res.end('"/></body></html>');

tar.gz file is just a tar file that's been gzipped. Both tar and gzip are available for windows.

If you like GUIs (Graphical user interface), 7zip can pack with both tar and gzip.

Pretty sure nobody answer your question to your exact terms, you want it for dynamic text

var newString = myString.substring( myString.indexOf( "," ) +1, myString.length );

It takes a substring from the first comma, to the end

In my case it was due to wrong import of the @Test annotation

Make sure you are using the following import

import org.junit.jupiter.api.Test;

You can technically use colons and periods in id/name attributes, but I would strongly suggest avoiding both.

In CSS (and several JavaScript libraries like jQuery), both the period and the colon have special meaning and you will run into problems if you're not careful. Periods are class selectors and colons are pseudo-selectors (eg., ":hover" for an element when the mouse is over it).

If you give an element the id "my.cool:thing", your CSS selector will look like this:

#my.cool:thing { ... /* some rules */ ... }

Which is really saying, "the element with an id of 'my', a class of 'cool' and the 'thing' pseudo-selector" in CSS-speak.

Stick to A-Z of any case, numbers, underscores and hyphens. And as said above, make sure your ids are unique.

That should be your first concern.

    return "redirect:/apps/add"
} 

@RequestMapping(path="/apps/add", method=RequestMethod.GET)
public String addAppss(Model model) {
    String error = model.asMap().get("error");
}

Similarly to other languages, the fastest "modulo 2" (odd/even) operation is done using the bitwise and operator:

if x & 1:
    return 'odd'
else:
    return 'even'

Using Bitwise AND operator

• The idea is to check whether the last bit of the number is set or not. If last bit is set then the number is odd, otherwise even.
• If a number is odd & (bitwise AND) of the Number by 1 will be 1, because the last bit would already be set. Otherwise it will give 0 as output.

another way is

nullif(trim(stringExpression),'') is not null

render() {
var myloop = [];

for (let i = 0; i < 10; i++) {
  myloop.push(
    <View key={i}>
    <Text>{i}</Text>
    </View>
  );
}

 return (

        <View >
          <Text >Welcome to React Native!</Text>
           {myloop}
        </View>


    );
  }
}

Since C-style strings are always terminated with the null character (\0), you can check whether the string is empty by writing

do {
   ...
} while (url[0] != '\0');

Alternatively, you could use the strcmp function, which is overkill but might be easier to read:

do {
   ...
} while (strcmp(url, ""));

Note that strcmp returns a nonzero value if the strings are different and 0 if they're the same, so this loop continues to loop until the string is nonempty.

Hope this helps!

I was looking at the same statistics problems. The approach you are thinking it is good and it will work. (Answer to the sorting has been given)

But in case you are interested in algorithm performance, I think there are a couple of algorithms that have better performance than just sorting the array, one (QuickSelect) is indicated by @bruce-feist's answer and is very well explained.

[Java implementation: https://discuss.leetcode.com/topic/14611/java-quick-select ]

But there is a variation of this algorithm named median of medians, you can find a good explanation on this link: http://austinrochford.com/posts/2013-10-28-median-of-medians.html

Java implementation of this: - https://stackoverflow.com/a/27719796/957979

I have done it for array from strings. This solution is adjusted for string in body.

The "native" way from Alamofire 4:

struct JSONStringArrayEncoding: ParameterEncoding {
    private let myString: String

    init(string: String) {
        self.myString = string
    }

    func encode(_ urlRequest: URLRequestConvertible, with parameters: Parameters?) throws -> URLRequest {
        var urlRequest = urlRequest.urlRequest

        let data = myString.data(using: .utf8)!

        if urlRequest?.value(forHTTPHeaderField: "Content-Type") == nil {
            urlRequest?.setValue("application/json", forHTTPHeaderField: "Content-Type")
        }

        urlRequest?.httpBody = data

        return urlRequest!
    }
}

And then make your request with:

Alamofire.request("your url string", method: .post, parameters: [:], encoding: JSONStringArrayEncoding.init(string: "My string for body"), headers: [:])

Try this

if(!a || a.length === 0)

The answers given here didn't fully convince me. So instead, I make another example.

public void passOn(Consumer<Animal> consumer, Supplier<Animal> supplier) {
    consumer.accept(supplier.get());
}

sounds fine, doesn't it? But you can only pass Consumers and Suppliers for Animals. If you have a Mammal consumer, but a Duck supplier, they should not fit although both are animals. In order to disallow this, additional restrictions have been added.

Instead of the above, we have to define relationships between the types we use.

E. g.,

public <A extends Animal> void passOn(Consumer<A> consumer, Supplier<? extends A> supplier) {
    consumer.accept(supplier.get());
}

makes sure that we can only use a supplier which provides us the right type of object for the consumer.

OTOH, we could as well do

public <A extends Animal> void passOn(Consumer<? super A> consumer, Supplier<A> supplier) {
    consumer.accept(supplier.get());
}

where we go the other way: we define the type of the Supplier and restrict that it can be put into the Consumer.

We even can do

public <A extends Animal> void passOn(Consumer<? super A> consumer, Supplier<? extends A> supplier) {
    consumer.accept(supplier.get());
}

where, having the intuitive relations Life -> Animal -> Mammal -> Dog, Cat etc., we could even put a Mammal into a Life consumer, but not a String into a Life consumer.

Set editable to False and default to your default value.

Also, your id field is unnecessary. Django will add it automatically.

 pip3 install --trusted-host pypi.org --trusted-host files.pythonhosted.org <app>

This may be the easiest method

• Right click on the project and select "Add Service Reference..."
• In the Address: box, enter the physical path (C:\test\project....) of the downloaded/Modified wsdl.
• Hit Go

First make sure you have installed git scm or not. If not, here's the link for windows: https://git-for-windows.github.io/ Then go to Android studio and configure the link of Git to the place where you installed your git(probably in C:/program files) I referred to a YouTube video to solve my issue. You can refer it here: https://www.youtube.com/watch?v=faEd2syXypE

I've shared a sample project which solve this problem using custom_rules.xml build script and a few lines of code.

I used it on my own project and it is runs flawless on 1M+ devices (from android-8 to the latest android-19). Hope it helps.

Add the below to your ~/.bash_profile:

export DYLD_LIBRARY_PATH=/usr/local/mysql/lib:$DYLD_LIBRARY_PATH

This worked for me

You can also use Rsync and find. For find:

find $FOLDER -type f | cut -d/ -f2- | sort > /tmp/file_list_$FOLDER

But files with the same names and in the same subfolders, but with different content, will not be shown in the lists.

If you are a fan of GUI, you may check Meld that @Alexander mentioned. It works fine in both windows and linux.

The problem is the import of ProjectsListComponent in your ProjectsModule. You should not import that, but add it to the export array, if you want to use it outside of your ProjectsModule.

Other issues are your project routes. You should add these to an exportable variable, otherwise it's not AOT compatible. And you should -never- import the BrowserModule anywhere else but in your AppModule. Use the CommonModule to get access to the *ngIf, *ngFor...etc directives:

@NgModule({
  declarations: [
     ProjectsListComponent
  ],
  imports: [
    CommonModule,
    RouterModule.forChild(ProjectRoutes)
  ],
  exports: [
     ProjectsListComponent
  ]
})

export class ProjectsModule {}

project.routes.ts

export const ProjectRoutes: Routes = [
      { path: 'projects', component: ProjectsListComponent }
]

Correct on all fronts. Outside of a character class (that's what the "square brackets" are called) the hyphen has no special meaning, and within a character class, you can place a hyphen as the first or last character in the range (e.g. [-a-z] or [0-9-]), OR escape it (e.g. [a-z\-0-9]) in order to add "hyphen" to your class.

It's more common to find a hyphen placed first or last within a character class, but by no means will you be lynched by hordes of furious neckbeards for choosing to escape it instead.

(Actually... my experience has been that a lot of regex is employed by folks who don't fully grok the syntax. In these cases, you'll typically see everything escaped (e.g. [a-z\%\$\#\@\!\-\_]) simply because the engineer doesn't know what's "special" and what's not... so they "play it safe" and obfuscate the expression with loads of excessive backslashes. You'll be doing yourself, your contemporaries, and your posterity a huge favor by taking the time to really understand regex syntax before using it.)

Great question!

The HTTP Content-Type for .ogg should be application/ogg (video/ogg for .ogv) and for .mp4 it should be video/mp4. You can check using the Web Sniffer.

You can just use

db.serverStatus().connections

Also, this function can help you spot the IP addresses connected to your Mongo DB

db.currentOp(true).inprog.forEach(function(x) { print(x.client) })

We can also use this with the $_GET method

$employee_id = 'EMP-1234';

header('Location: employee.php?id='.$employee_id);

Perhaps something like this, assuming that there are many of these rows inside of the datatable and that each row is row:

List<string[]> MyStringArrays = new List<string[]>();
foreach( var row in datatable.rows )//or similar
{
 MyStringArrays.Add( new string[]{row.Name,row.Address,row.Age.ToString()} );
}

You could then access one:

MyStringArrays.ElementAt(0)[1]

If you use linqpad, here is a very simple scenario of your example:

class Datatable
{
 public List<data> rows { get; set; }
 public Datatable(){
  rows = new List<data>();
 }
}

class data
{
 public string Name { get; set; }
 public string Address { get; set; }
 public int Age { get; set; }
}

void Main()
{
 var datatable = new Datatable();
 var r = new data();
 r.Name = "Jim";
 r.Address = "USA";
 r.Age = 23;
 datatable.rows.Add(r);
 List<string[]> MyStringArrays = new List<string[]>();
 foreach( var row in datatable.rows )//or similar
 {
  MyStringArrays.Add( new string[]{row.Name,row.Address,row.Age.ToString()} );
 }
 var s = MyStringArrays.ElementAt(0)[1];
 Console.Write(s);//"USA"
}

.csv field sizes are controlled via [Python 3.Docs]: csv.field_size_limit([new_limit]) (emphasis is mine):

Returns the current maximum field size allowed by the parser. If new_limit is given, this becomes the new limit.

It is set by default to 131072 or 0x20000 (128k), which should be enough for any decent .csv:

>>> import csv
>>>
>>>
>>> limit0 = csv.field_size_limit()
>>> limit0
131072
>>> "0x{0:016X}".format(limit0)
'0x0000000000020000'

However, when dealing with a .csv file (with the correct quoting and delimiter) having (at least) one field longer than this size, the error pops up.
To get rid of the error, the size limit should be increased (to avoid any worries, the maximum possible value is attempted).

Behind the scenes (check [GitHub]: python/cpython - (master) cpython/Modules/_csv.c for implementation details), the variable that holds this value is a C long ([Wikipedia]: C data types), whose size varies depending on CPU architecture and OS (ILP). The classical difference: for a 64bit OS (and Python build), the long type size (in bits) is:

• Nix: 64
• Win: 32

When attempting to set it, the new value is checked to be in the long boundaries, that's why in some cases another exception pops up (because sys.maxsize is typically 64bit wide - encountered on Win):

>>> import sys, ctypes as ct
>>>
>>>
>>> sys.platform, sys.maxsize, ct.sizeof(ct.c_void_p) * 8, ct.sizeof(ct.c_long) * 8
('win32', 9223372036854775807, 64, 32)
>>>
>>> csv.field_size_limit(sys.maxsize)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
OverflowError: Python int too large to convert to C long

To avoid running into this problem, set the (maximum possible) limit (LONG_MAX), using an artifice (thanks to [Python 3.Docs]: ctypes - A foreign function library for Python). It should work on Python 3 and Python 2, on any CPU / OS.

>>> csv.field_size_limit(int(ct.c_ulong(-1).value // 2))
131072
>>> limit1 = csv.field_size_limit()
>>> limit1
2147483647
>>> "0x{0:016X}".format(limit1)
'0x000000007FFFFFFF'

64bit Python on a Nix like OS:

>>> import sys, csv, ctypes as ct
>>>
>>>
>>> sys.platform, sys.maxsize, ct.sizeof(ct.c_void_p) * 8, ct.sizeof(ct.c_long) * 8
('linux', 9223372036854775807, 64, 64)
>>>
>>> csv.field_size_limit()
131072
>>>
>>> csv.field_size_limit(int(ct.c_ulong(-1).value // 2))
131072
>>> limit1 = csv.field_size_limit()
>>> limit1
9223372036854775807
>>> "0x{0:016X}".format(limit1)
'0x7FFFFFFFFFFFFFFF'

For 32bit Python, things should run smoothly without the artifice (as both sys.maxsize and LONG_MAX are 32bit wide).
If this maximum value is still not enough, then the .csv would need manual intervention in order to be processed from Python.

Hope this helps.

Having run into this problem many times myself, I wrote up a small function (inspired by @aaron-hall's answer) & tests that does what I would have expected sys.getsizeof to do:

https://github.com/bosswissam/pysize

If you're interested in the backstory, here it is

EDIT: Attaching the code below for easy reference. To see the most up-to-date code, please check the github link.

    import sys

    def get_size(obj, seen=None):
        """Recursively finds size of objects"""
        size = sys.getsizeof(obj)
        if seen is None:
            seen = set()
        obj_id = id(obj)
        if obj_id in seen:
            return 0
        # Important mark as seen *before* entering recursion to gracefully handle
        # self-referential objects
        seen.add(obj_id)
        if isinstance(obj, dict):
            size += sum([get_size(v, seen) for v in obj.values()])
            size += sum([get_size(k, seen) for k in obj.keys()])
        elif hasattr(obj, '__dict__'):
            size += get_size(obj.__dict__, seen)
        elif hasattr(obj, '__iter__') and not isinstance(obj, (str, bytes, bytearray)):
            size += sum([get_size(i, seen) for i in obj])
        return size

Ansible has a version_compare filter since 1.6. You can do something like below in when conditional:

when: ansible_distribution_version | version_compare('12.04', '>=')

This will give you support for major & minor versions comparisons and you can compare versions using operators like:

<, lt, <=, le, >, gt, >=, ge, ==, =, eq, !=, <>, ne

You can find more information about this here: Ansible - Version comparison filters

Otherwise if you have really simple case you can use what @ProfHase85 suggested

I was recently shown this website for liquid layouts using CSS. http://matthewjamestaylor.com/blog/perfect-multi-column-liquid-layouts (Take a look at the demo pages in the links below).

The author now provides an example for fixed width layouts. Check out; http://matthewjamestaylor.com/blog/how-to-convert-a-liquid-layout-to-fixed-width.

This provides the following example(s), http://matthewjamestaylor.com/blog/ultimate-2-column-left-menu-pixels.htm (for two column layout like you are after I think)

http://matthewjamestaylor.com/blog/fixed-width-or-liquid-layout.htm (for three column layout).

Sorry for so many links to this guys site, but I think it is an AWESOME resource.

In order to use word-wrap: break-word, you need to set a width (in px). For example:

div {
    width: 250px;
    word-wrap: break-word;
}

word-wrap is a CSS3 property, but it should work in all browsers, including IE 5.5-9.

ALT+ENTER was far from eclipse habit ,in IDEA for me mouse over did not work , so in setting>IDESetting>Keymap>Show intention actions and quick-fixes I changed it to mouse left click , It did not support mouse over! but mouse left click was OK and closest to my intention.

In Internet Explorer use the filter property.

In webkit and Firefox there is currently no way to desatuarte an image solely with CSS. so you will need to use either canvas or SVG for a client side solution.

But I think using SVG is more elegant. check out my blog post for the SVG solution that works for both Firefox and webkit: http://webdev.brillout.com/2010/10/desaturate-image-without-javascript.html

And strictly speaking since SVG is HTML the solution is pure html+css :-)

Here is an elegant solution that requires a little work upfront when adding a new project but handles the process very easily.

The idea is that each project links to a Solution file that only contains the assembly version information. So your build process only has to update a single file and all of the assembly versions pull from the one file upon compilation.

Steps:

1. Add a class to you solution file *.cs file, I named min SharedAssemblyProperties.cs
2. Remove all of the cs information from that new file
3. Cut the assembly information from an AssemblyInfo file: [assembly: AssemblyVersion("1.0.0.0")] [assembly: AssemblyFileVersion("1.0.0.0")]
4. Add the statement "using System.Reflection;" to the file and then paste data into your new cs file (ex SharedAssemblyProperties.cs)
5. Add an existing item to you project (wait... read on before adding the file)
6. Select the file and before you click Add, click the dropdown next to the add button and select "Add As Link".
7. Repeat steps 5 and 6 for all existing and new projects in the solution

When you add the file as a link, it stores the data in the project file and upon compilation pulls the assembly version information from this one file.

In you source control, you add a bat file or script file that simply increments the SharedAssemblyProperties.cs file and all of your projects will update their assembly information from that file.

This answer was a little more detailed than I thought but read it through.

DLL:
In most cases, a DLL file is a library. There are a couple of types of libraries, dynamic and static - read about the difference. DLL stands for dynamic link library which tells us that it's a part of the program but not the whole thing. It's made of reusable software components (library) which you could use for more than a single program. Bear in mind that it's always possible to use the library source code in many applications using copy-paste, but the idea of a DLL/Static Library is that you could update the code of a library and at the same time update all the applications using it - without compiling.

For example:
Imagine you're creating a Windows GUI component like a Button. In most cases you'd want to re-use the code you've written because it's a complex but a common component - You want many applications to use it but you don't want to give them the source code You can't copy-paste the code for the button in every program, so you decide you want to create a DL-Library (DLL).

This "button" library is required by EXEcutables to run, and without it they will not run because they don't know how to create the button, only how to talk to it.

Likewise, a DLL cannot be executed - run, because it's only a part of the program but doesn't have the information required to create a "process".

EXE:
An executable is the program. It knows how to create a process and how to talk to the DLL. It needs the DLL to create a button, and without it the application doesn't run - ERROR.

hope this helps....

Do this using rs.next():

while (rs.next())
{
    ...
}

If the result set is empty, the code inside the loop won't execute.

Also You Can Do like This.

 public boolean isPasswordValid(String password) {


    String regExpn =
            "^(?=.*[0-9])(?=.*[a-z])(?=.*[A-Z])(?=.*[@#$%^&+=])(?=\\S+$).{8,}$";

    CharSequence inputStr = password;

    Pattern pattern = Pattern.compile(regExpn,Pattern.CASE_INSENSITIVE);
    Matcher matcher = pattern.matcher(inputStr);

    if(matcher.matches())
        return true;
    else
        return false;
}

The following configs works on Cent OS 6 or earlier

As stated above first have to disable selinux.

Step 1 nano /etc/sysconfig/selinux

Make sure the file has this configurations

SELINUX=disabled

SELINUXTYPE=targeted

Then restart the system

Step 2

iptables -A INPUT -m state --state NEW -p tcp --dport 8080 -j ACCEPT

Step 3

sudo service iptables save

For Cent OS 7

step 1

firewall-cmd --zone=public --permanent --add-port=8080/tcp

Step 2

firewall-cmd --reload

Addressing the above "too small a task to require a library" issue by a straightforward implementation:

def sizeof_fmt(num, suffix='B'):
    for unit in ['','Ki','Mi','Gi','Ti','Pi','Ei','Zi']:
        if abs(num) < 1024.0:
            return "%3.1f%s%s" % (num, unit, suffix)
        num /= 1024.0
    return "%.1f%s%s" % (num, 'Yi', suffix)

Supports:

• all currently known binary prefixes
• negative and positive numbers
• numbers larger than 1000 Yobibytes
• arbitrary units (maybe you like to count in Gibibits!)

Example:

>>> sizeof_fmt(168963795964)
'157.4GiB'

SOLUTIONS

1. Sometimes the project is created before installing g++. So install g++ first and then recreate your project. This worked for me.
2. Paste the following line in CMakeCache.txt: CMAKE_CXX_COMPILER:FILEPATH=/usr/bin/c++

Note the path to g++ depends on OS. I have used my fedora path obtained using which g++
