The DataView object itself is used to loop through DataView rows.

DataView rows are represented by the DataRowView object. The DataRowView.Row property provides access to the original DataTable row.

C#

foreach (DataRowView rowView in dataView)
{
    DataRow row = rowView.Row;
    // Do something //
}

VB.NET

For Each rowView As DataRowView in dataView
    Dim row As DataRow = rowView.Row
    ' Do something '
Next

a = np.arange(18).reshape(9,2)
b = a.reshape(3,3,2).swapaxes(0,2)

# a: 
array([[ 0,  1],
       [ 2,  3],
       [ 4,  5],
       [ 6,  7],
       [ 8,  9],
       [10, 11],
       [12, 13],
       [14, 15],
       [16, 17]])


# b:
array([[[ 0,  6, 12],
        [ 2,  8, 14],
        [ 4, 10, 16]],

       [[ 1,  7, 13],
        [ 3,  9, 15],
        [ 5, 11, 17]]])

Nobody have mention the new type of "Pull to refresh" which shows on top of the action bar like in the Google Now or Gmail application.

There is a library ActionBar-PullToRefresh which works exactly the same.

This is a late answer but if anyone reading this question is using razor, what you should remember is that razor encodes everything by default, but by using MvcHtmlString in your html helpers you can tell razor that it doesn't need to encode it.

If you want razor to not encode a string use

@Html.Raw("<span>hi</span>")

Decompiling Raw(), shows us that it's wrapping the string in a HtmlString

public IHtmlString Raw(string value) {
    return new HtmlString(value); 
}

"HtmlString only exists in ASP.NET 4.

MvcHtmlString was a compatibility shim added to MVC 2 to support both .NET 3.5 and .NET 4. Now that MVC 3 is .NET 4 only, it's a fairly trivial subclass of HtmlString presumably for MVC 2->3 for source compatibility." source

Specify the maxrecursion option at the end of the query:

...
from EmployeeTree
option (maxrecursion 0)

That allows you to specify how often the CTE can recurse before generating an error. Maxrecursion 0 allows infinite recursion.

6/1/2011 4:08:40 PM Local
6/1/2011 4:08:40 PM Utc

from

DateTime dt = DateTime.Now;            
Console.WriteLine("{0} {1}", dt, dt.Kind);
DateTime ut = DateTime.SpecifyKind(dt, DateTimeKind.Utc);
Console.WriteLine("{0} {1}", ut, ut.Kind);

Offsetting the markers isn't a real solution if they're located in the same building. What you might want to do is modify the markerclusterer.js like so:

1. Add a prototype click method in the MarkerClusterer class, like so - we will override this later in the map initialize() function:

   MarkerClusterer.prototype.onClick = function() { 
       return true; 
   };
   

2. In the ClusterIcon class, add the following code AFTER the clusterclick trigger:

   // Trigger the clusterclick event.
   google.maps.event.trigger(markerClusterer, 'clusterclick', this.cluster_);
   
   var zoom = this.map_.getZoom();
   var maxZoom = markerClusterer.getMaxZoom();
   // if we have reached the maxZoom and there is more than 1 marker in this cluster
   // use our onClick method to popup a list of options
   if (zoom >= maxZoom && this.cluster_.markers_.length > 1) {
      return markerClusterer.onClickZoom(this);
   }
   

3. Then, in your initialize() function where you initialize the map and declare your MarkerClusterer object:

   markerCluster = new MarkerClusterer(map, markers);
   // onClickZoom OVERRIDE
   markerCluster.onClickZoom = function() { return multiChoice(markerCluster); }
   

   Where multiChoice() is YOUR (yet to be written) function to popup an InfoWindow with a list of options to select from. Note that the markerClusterer object is passed to your function, because you will need this to determine how many markers there are in that cluster. For example:

   function multiChoice(mc) {
        var cluster = mc.clusters_;
        // if more than 1 point shares the same lat/long
        // the size of the cluster array will be 1 AND
        // the number of markers in the cluster will be > 1
        // REMEMBER: maxZoom was already reached and we can't zoom in anymore
        if (cluster.length == 1 && cluster[0].markers_.length > 1)
        {
             var markers = cluster[0].markers_;
             for (var i=0; i < markers.length; i++)
             {
                 // you'll probably want to generate your list of options here...
             }
   
             return false;
        }
   
        return true;
   }
   

use docker top

docker top <container ID>

Another tip: if you want to have cleaner PHP code, you can create a VIEW in the database, e.g.

For example:

CREATE VIEW view_news AS
SELECT
  news.id news_id,
  user.id user_id,
  user.name user_name,
  [ OTHER FIELDS ]
FROM news, users
WHERE news.user_id = user.id;

In PHP:

$sql = "SELECT * FROM view_news";

• cd /usr/local
• git status
• Discard all the changes (unless you actually want to try to commit to Homebrew - you probably don't)
• git status til it's clean
• brew update

I'd download PuTTY and run a telnet session on port 80 to the webserver you want

HEAD /resource HTTP/1.1
Host: www.example.com

You could alternatively download Perl and try LWP's HEAD command. Or write your own script.

unfortunately we can't use in MySQL after INSERT or UPDATE description, like in Oracle

Next to being in the wrong directory I just tripped about another variant:

I had a File.open(my_file).each {|line| puts line} exploding but there was something by that name in the directory I was working in (ls in the command line showed the name). I checked with a File.exists?(my_file) which strangely returned false. Explanation: my_file was a symlink which target didn't exist anymore! Since File.exists? will follow a symlink it will say false though the link is still there.

You can use pandas. It does take some extra memory so it's not always possible, but it's very fast and easy to use.

import pandas as pd 
pd.DataFrame(np_array).to_csv("path/to/file.csv")

if you don't want a header or index, use to_csv("/path/to/file.csv", header=None, index=None)

Go to the Window menu and choose "Web Publish Activity" There will be a cancel button. Cancel button on "Web Publish Activity" tab

using List Comprehension:

>>> L = [1]*5
>>> [x+1 for x in L]
[2, 2, 2, 2, 2]
>>> 

which roughly translates to using a for loop:

>>> newL = []
>>> for x in L:
...     newL+=[x+1]
... 
>>> newL
[2, 2, 2, 2, 2]

or using map:

>>> map(lambda x:x+1, L)
[2, 2, 2, 2, 2]
>>> 

How to print:

NSLog(@"Something To Print");

Or

NSString * someString = @"Something To Print";
NSLog(@"%@", someString);

For other types of variables, use:

NSLog(@"%@", someObject);
NSLog(@"%i", someInt);
NSLog(@"%f", someFloat);
/// etc...

Can you show it in phone?

Not by default, but you could set up a display to show you.

Update for Swift

print("Print this string")
print("Print this \(variable)")
print("Print this ", variable)
print(variable)

With Android Studio 2.2.3 on OSX I just used the top menu:

Build > Build APK

It opened Finder with the .apk file. This won't generate a signed APK. You can select Generate Signed APK from the same menu if needed.

I'm using the same approach, I suggest to write the singleton a little better:

public static MyApp getInstance() {

    if (instance == null) {
        synchronized (MyApp.class) {
            if (instance == null) {
                instance = new MyApp ();
            }
        }
    }

    return instance;
}

but I'm not using everywhere, I use getContext() and getApplicationContext() where I can do it!

You can try this

 var str = 'hello     world  !!';
 str = str.replace(/\s+/g, '-');

It will even replace multiple spaces with single '-'.

When we convert a UTC timestamp (2017-11-06 20:15:33 -08:00) into a Date object, the time zone is zeroed out to GMT. For calculating time intervals, this isn't an issue, but it can be for rendering times in the UI.

I favor the RFC3339 format (2017-11-06T20:15:33-08:00) for its universality. The date format in Swift is yyyy-MM-dd'T'HH:mm:ssXXXXX but RFC3339 allows us to take advantage of the ISO8601DateFormatter:

func getDateFromUTC(RFC3339: String) -> Date? {
    let formatter = ISO8601DateFormatter()
    return formatter.date(from: RFC3339)
}

RFC3339 also makes time-zone extraction simple:

func getTimeZoneFromUTC(RFC3339: String) -> TimeZone? {

    switch RFC3339.suffix(6) {

    case "+05:30":
        return TimeZone(identifier: "Asia/Kolkata")

    case "+05:45":
        return TimeZone(identifier: "Asia/Kathmandu")

    default:
        return nil

    }

}

There are 37 or so other time zones we'd have to account for and it's up to you to determine which ones, because there is no definitive list. Some standards count fewer time zones, some more. Most time zones break on the hour, some on the half hour, some on 0:45, some on 0:15.

We can combine the two methods above into something like this:

func getFormattedDateFromUTC(RFC3339: String) -> String? {

    guard let date = getDateFromUTC(RFC3339: RFC3339),
        let timeZone = getTimeZoneFromUTC(RFC3339: RFC3339) else {
            return nil
    }

    let formatter = DateFormatter()
    formatter.dateFormat = "h:mma EEE, MMM d yyyy"
    formatter.amSymbol = "AM"
    formatter.pmSymbol = "PM"
    formatter.timeZone = timeZone // preserve local time zone
    return formatter.string(from: date)

}

And so the string "2018-11-06T17:00:00+05:45", which represents 5:00PM somewhere in Kathmandu, will print 5:00PM Tue, Nov 6 2018, displaying the local time, regardless of where the machine is.

As an aside, I recommend storing dates as strings remotely (including Firestore which has a native date object) because, I think, remote data should agnostic to create as little friction between servers and clients as possible.

Here's a derived HorizontalScrollView I wrote to handle notifications about scrolling and scroll ending. It properly handles when a user has stopped actively scrolling and when it fully decelerates after a user lets go:

public class ObservableHorizontalScrollView extends HorizontalScrollView {
    public interface OnScrollListener {
        public void onScrollChanged(ObservableHorizontalScrollView scrollView, int x, int y, int oldX, int oldY);
        public void onEndScroll(ObservableHorizontalScrollView scrollView);
    }

    private boolean mIsScrolling;
    private boolean mIsTouching;
    private Runnable mScrollingRunnable;
    private OnScrollListener mOnScrollListener;

    public ObservableHorizontalScrollView(Context context) {
        this(context, null, 0);
    }

    public ObservableHorizontalScrollView(Context context, AttributeSet attrs) {
        this(context, attrs, 0);
    }

    public ObservableHorizontalScrollView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    @Override
    public boolean onTouchEvent(MotionEvent ev) {
        int action = ev.getAction();

        if (action == MotionEvent.ACTION_MOVE) {
            mIsTouching = true;
            mIsScrolling = true;
        } else if (action == MotionEvent.ACTION_UP || action == MotionEvent.ACTION_CANCEL) {
            if (mIsTouching && !mIsScrolling) {
                if (mOnScrollListener != null) {
                    mOnScrollListener.onEndScroll(this);
                }
            }

            mIsTouching = false;
        }

        return super.onTouchEvent(ev);
    }

    @Override
    protected void onScrollChanged(int x, int y, int oldX, int oldY) {
        super.onScrollChanged(x, y, oldX, oldY);

        if (Math.abs(oldX - x) > 0) {
            if (mScrollingRunnable != null) {
                removeCallbacks(mScrollingRunnable);
            }

            mScrollingRunnable = new Runnable() {
                public void run() {
                    if (mIsScrolling && !mIsTouching) {
                        if (mOnScrollListener != null) {
                            mOnScrollListener.onEndScroll(ObservableHorizontalScrollView.this);
                        }
                    }

                    mIsScrolling = false;
                    mScrollingRunnable = null;
                }
            };

            postDelayed(mScrollingRunnable, 200);
        }

        if (mOnScrollListener != null) {
            mOnScrollListener.onScrollChanged(this, x, y, oldX, oldY);
        }
    }

    public OnScrollListener getOnScrollListener() {
        return mOnScrollListener;
    }

    public void setOnScrollListener(OnScrollListener mOnEndScrollListener) {
        this.mOnScrollListener = mOnEndScrollListener;
    }

}

Easy Workaround (no VBA required)

1. Right Click Table, expand "Table" context manu, select "External Data Properties"
2. Click button "Connection Properties" (labelled in tooltip only)
3. Go-to Tab "Definition"

From here, edit the SQL directly by adding '?' wherever you want a parameter. Works the same way as before except you don't get nagged.

This answer seems quite outdated and not adapt for nowadays single page applications. In my case I found the solution thank to this aricle where a simple but effective solution is proposed:

html,
body {
  position: fixed;
  overflow: hidden;
}

This solution it's not applicable if your body is your scroll container.

To be complete, a short introduction for "shell noobs":

First of all, start your shell - you can find it inside the common desktop environments under the name "Terminal" or "Shell" somewhere in the desktops application menu.

You can also try using the key combo CTRL+F2, followed by one of those commands (depending on the desktop envrionment you're using) and the ENTER key:

xfce4-terminal
gnome-console
terminal
rxvt
konsole

If all of the above fail, try using xterm - it'll work in most cases.

Hint for the following commands: Execute the commands without the $ - it's just a marker identifying that you're on the shell.

After that just fire up mongod with the --version flag:

$ mongod --version

It shows you then something like

$ mongod --version
db version v2.4.6
Wed Oct 16 16:17:00.241 git version: nogitversion

To update it just execute

$ sudo apt-get update

and then

$ sudo apt-get install mongodb

This is a tool that will help you, i installed it myself

Here is the link

It appears that the Internet Explorer driver does not interact with everything in the same way the other drivers do and checkboxes is one of those cases.

The trick with checkboxes is to send the Space key instead of using a click (only needed on Internet Explorer), like so in C#:

if (driver.Capabilities.BrowserName.Equals(“internet explorer"))
    driver.findElement(By.id("idOfTheElement").SendKeys(Keys.Space);
else
    driver.findElement(By.id("idOfTheElement").Click();

set -x

Prints a trace of simple commands, for commands, case commands, select commands, and arithmetic for commands and their arguments or associated word lists after they are expanded and before they are executed. The value of the PS4 variable is expanded and the resultant value is printed before the command and its expanded arguments.

[source]

Example

set -x
echo `expr 10 + 20 `
+ expr 10 + 20
+ echo 30
30

set +x
echo `expr 10 + 20 `
30

Above example illustrates the usage of set -x. When it is used, above arithmetic expression has been expanded. We could see how a singe line has been evaluated step by step.

• First step expr has been evaluated.
• Second step echo has been evaluated.

To know more about set ? visit this link

when it comes to your shell script,

[ "$DEBUG" == 'true' ] && set -x

Your script might have been printing some additional lines of information when the execution mode selected as DEBUG. Traditionally people used to enable debug mode when a script called with optional argument such as -d

Define a class to store your data first

public class YourDataClass {

    private String messageType;
    private Timestamp timestamp;
    private int count;
    private int version;

    // your get/setters
    ...........
}

And then initialize your map:

Map<Integer, YourDataClass> map = new HashMap<Integer, YourDataClass>();

Your variable size is declared as: float size;

You can't use a floating point variable as the size of an array - it needs to be an integer value.

You could cast it to convert to an integer:

float *temp = new float[(int)size];

Your other problem is likely because you're writing outside of the bounds of the array:

   float *temp = new float[size];

    //Getting input from the user
    for (int x = 1; x <= size; x++){
        cout << "Enter temperature " << x << ": ";

        // cin >> temp[x];
        // This should be:
        cin >> temp[x - 1];
    }

Arrays are zero based in C++, so this is going to write beyond the end and never write the first element in your original code.

The Log class:

API for sending log output.

Generally, use the Log.v() Log.d() Log.i() Log.w() and Log.e() methods.

The order in terms of verbosity, from least to most is ERROR, WARN, INFO, DEBUG, VERBOSE. Verbose should never be compiled into an application except during development. Debug logs are compiled in but stripped at runtime. Error, warning and info logs are always kept.

Outside of Android, System.out.println(String msg) is used.

    String start_dt = "2011-01-01"; // Input String

    SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd"); // Existing Pattern
    Date getStartDt = formatter.parse(start_dt); //Returns Date Format according to existing pattern

    SimpleDateFormat simpleDateFormat = new SimpleDateFormat("MM-dd-yyyy");// New Pattern
    String formattedDate = simpleDateFormat.format(getStartDt); // Format given String to new pattern

    System.out.println(formattedDate); //outputs: 01-01-2011

Sometimes yes they are related, and sometimes no they are not related, actually we sometimes use more space to get faster algorithms as in dynamic programming https://www.codechef.com/wiki/tutorial-dynamic-programming dynamic programming uses memoization or bottom-up, the first technique use the memory to remember the repeated solutions so the algorithm needs not to recompute it rather just get them from a list of solutions. and the bottom-up approach start with the small solutions and build upon to reach the final solution. Here two simple examples, one shows relation between time and space, and the other show no relation: suppose we want to find the summation of all integers from 1 to a given n integer: code1:

sum=0
for i=1 to n
   sum=sum+1
print sum

This code used only 6 bytes from memory i=>2,n=>2 and sum=>2 bytes therefore time complexity is O(n), while space complexity is O(1) code2:

array a[n]
a[1]=1
for i=2 to n
    a[i]=a[i-1]+i
print a[n]

This code used at least n*2 bytes from the memory for the array therefore space complexity is O(n) and time complexity is also O(n)

<?php

The right way to do this is:

composer remove jenssegers/mongodb --update-with-dependencies

I must admit the flag here is not quite obvious as to what it will do.

Update

composer remove jenssegers/mongodb

As of v1.0.0-beta2 --update-with-dependencies is the default and is no longer required.

all you are right! other way to getting !

There is no need to use angular http, you can get with js native functions

You can simply use CSS transitions, see this fiddle

.on {
color:#fff;
transition:all 1s;
}

.off{
color:#000;
transition:all 1s;
}

$time = time();
$check = $time+date("Z",$time);
echo strftime("%B %d, %Y @ %H:%M:%S UTC", $check);

You can use following command -

LENGTH(TRIM(TRANSLATE(string1, '+-.0123456789', '')))

This will return NULL if your string1 is Numeric

your query would be -

select * from tablename 
where LENGTH(TRIM(TRANSLATE(X, '+-.0123456789', ''))) is null

Similar to Yipio, I added notab="notab" as an attribute to any element I wanted to disable the tab too. My jQuery is then one line.

$('input[notab=notab]').on('keydown', function(e){ if (e.keyCode == 9)  e.preventDefault() });

Btw, keypress doesn't work for many control keys.

Here is simple steps add this gradle:

dependencies {
  compile "com.google.firebase:firebase-messaging:9.0.0"
}

No extra permission are needed in manifest like GCM. No receiver is needed to manifest like GCM. With FCM, com.google.android.gms.gcm.GcmReceiver is added automatically.

Migrate your listener service

A service extending InstanceIDListenerService is now required only if you want to access the FCM token.

This is needed if you want to

• Manage device tokens to send a messages to single device directly, or Send messages to device group, or
• Send messages to device group, or
• Subscribe devices to topics with the server subscription management API.

Add Service in manifest

<service
    android:name=".MyInstanceIDListenerService">
    <intent-filter>
        <action android:name="com.google.firebase.INSTANCE_ID_EVENT" />
    </intent-filter>
</service>

<service
    android:name=".MyFirebaseInstanceIDService">
    <intent-filter>
        <action android:name="com.google.firebase.INSTANCE_ID_EVENT"/>
    </intent-filter>
</service>

Change MyInstanceIDListenerService to extend FirebaseInstanceIdService, and update code to listen for token updates and get the token whenever a new token is generated.

public class MyInstanceIDListenerService extends FirebaseInstanceIdService {

  ...

  /**
   * Called if InstanceID token is updated. This may occur if the security of
   * the previous token had been compromised. Note that this is also called
   * when the InstanceID token is initially generated, so this is where
   * you retrieve the token.
   */
  // [START refresh_token]
  @Override
  public void onTokenRefresh() {
      // Get updated InstanceID token.
      String refreshedToken = FirebaseInstanceId.getInstance().getToken();
      Log.d(TAG, "Refreshed token: " + refreshedToken);
      // TODO: Implement this method to send any registration to your app's servers.
      sendRegistrationToServer(refreshedToken);
  }

}

I struggled a lot trying to implement posting a image from Android client to servlet using httpclient-4.3.5.jar, httpcore-4.3.2.jar, httpmime-4.3.5.jar. I always got a runtime error. I found out that basically you cannot use these jars with Android as Google is using older version of HttpClient in Android. The explanation is here http://hc.apache.org/httpcomponents-client-4.3.x/android-port.html. You need to get the httpclientandroidlib-1.2.1 jar from android http-client library. Then change your imports from or.apache.http.client to ch.boye.httpclientandroidlib. Hope this helps.

Previous answers cover about ASCII character at a certain index.

It is a little bit troublesome to get a Unicode character at a certain index in Python 2.

E.g., with s = '????????' which is <type 'str'>,

__getitem__, e.g., s[i] , does not lead you to where you desire. It will spit out semething like ?. (Many Unicode characters are more than 1 byte but __getitem__ in Python 2 is incremented by 1 byte.)

In this Python 2 case, you can solve the problem by decoding:

s = '????????'
s = s.decode('utf-8')
for i in range(len(s)):
    print s[i]

For Mac, your database files are located at:

/Applications/XAMPP/xamppfiles/var/mysql

You might need admin permissions to access or delete your files.

This should do the trick for you.

For one word:

if (!string.Contains("One"))

For two words:

if (!(string.Contains("One") && string.Contains("Two")))

No guarantee, but I suspect IE uses the older Protected Storage API.

npm rebuild it has solved my problem

Here is an example that should give you some idea..

=IIF(First(Fields!Gender.Value,"vw_BrgyClearanceNew")="Female" and 
(First(Fields!CivilStatus.Value,"vw_BrgyClearanceNew")="Married"),false,true)

I think you have to identify the datasource name or the table name where your data is coming from.

What you want to do is get the absolute path of the script (available via ${BASH_SOURCE[0]}) and then use this to get the parent directory and cd to it at the beginning of the script.

#!/bin/bash
parent_path=$( cd "$(dirname "${BASH_SOURCE[0]}")" ; pwd -P )

cd "$parent_path"
cat ../some.text

This will make your shell script work independent of where you invoke it from. Each time you run it, it will be as if you were running ./cat.sh inside dir.

Note that this script only works if you're invoking the script directly (i.e. not via a symlink), otherwise the finding the current location of the script gets a little more tricky)

• How do I convert my results to only hours and minutes
  • The accepted answer only returns days + hours. Minutes are not included.
• To provide a column that has hours and minutes, as hh:mm or x hours y minutes, would require additional calculations and string formatting.
• This answer shows how to get either total hours or total minutes as a float, using timedelta math, and is faster than using .astype('timedelta64[h]')
• Pandas Time Deltas User Guide
• Pandas Time series / date functionality User Guide
• python timedelta objects: See supported operations.
• The following sample data is already a datetime64[ns] dtype. It is required that all relevant columns are converted using pandas.to_datetime().

import pandas as pd

# test dataframe; the columns must be in a datetime format; use pandas.to_datetime if needed
df = pd.DataFrame(data)

# add a timedelta column if wanted. It's added here for information only
# df['time_delta_with_sub'] = df.from_date.sub(df.to_date)  # also works
df['time_delta'] = (df.from_date - df.to_date)

# create a column with timedelta as total hours, as a float type
df['tot_hour_diff'] = (df.from_date - df.to_date) / pd.Timedelta(hours=1)

# create a colume with timedelta as total minutes, as a float type
df['tot_mins_diff'] = (df.from_date - df.to_date) / pd.Timedelta(minutes=1)

I have implemented MultipartReader NuGet package for ASP.NET 4 for reading multipart form data. It is based on Multipart Form Data Parser, but it supports more than one file.

You may have accidentally corrupted the .git/index file with a sed on your project root (refactoring perhaps?) with something like:

sed -ri -e "s/$SEACHPATTERN/$REPLACEMENTTEXT/g" $(grep -Elr "$SEARCHPATERN" "$PROJECTROOT")

to avoid this in the future, just ignore binary files with your grep/sed:

sed -ri -e "s/$SEACHPATTERN/$REPLACEMENTTEXT/g" $(grep -Elr --binary-files=without-match "$SEARCHPATERN" "$PROJECTROOT")

Sometimes renaming .cpp to .mm is not good idea, especially when project is crossplatform. In this case for xcode project I open xcode project file throught TextEdit, found string which contents interest file, it should be like:

/* OnlineManager.cpp */ = {isa = PBXFileReference; fileEncoding = 4; lastKnownFileType = sourcecode.cpp.cpp; path = OnlineManager.cpp; sourceTree = "<group>"; };

and then change file type from sourcecode.cpp.cpp to sourcecode.cpp.objcpp

/* OnlineManager.cpp */ = {isa = PBXFileReference; fileEncoding = 4; lastKnownFileType = **sourcecode.cpp.objcpp**; path = OnlineManager.cpp; sourceTree = "<group>"; };

It is equivalent to rename .cpp to .mm

I will try to explain with a interesting and easy to understand example. :)

Assume that a organization organizes a chess tournament where 10 players (with equal chess playing skills) will challenge a professional champion chess player. And since chess is 1:1 game thus organizers have to conduct 10 games in time efficient manner so that they can finish the whole event as quickly as possible.

Hopefully following scenarios will easily describe multiple ways of conducting these 10 games:

1) SERIAL - lets say that the professional plays with each person one by one i.e. starts and finishes the game with one person and then starts the next game with next person and so on. In other words, they decided to conduct the games sequentially. So if one game takes 10 mins to complete then 10 games will take 100 mins, also assume that transition from one game to other takes 6 secs then for 10 games it will be 54 secs (approx. 1 min).

so the whole event will approximately complete in 101 mins (WORST APPROACH)

2) CONCURRENT - lets say that professional plays his turn and moves on to next player so all 10 players are playing simultaneously but the professional player is not with two person at a time, he plays his turn and moves on to next person. Now assume professional player takes 6 sec to play his turn and also transition time of professional player b/w two players is 6 sec so total transition time to get back to first player will be 1min (10x6sec). Therefore, by the time he is back to first person with, whom event was started, 2mins have passed (10xtime_per_turn_by_champion + 10xtransition_time=2mins)

Assuming that all player take 45sec to complete their turn so based on 10mins per game from SERIAL event the no. of rounds before a game finishes should 600/(45+6) = 11 rounds (approx)

So the whole event will approximately complete in 11xtime_per_turn_by_player_&_champion + 11xtransition_time_across_10_players = 11x51 + 11x60sec= 561 + 660 = 1221sec = 20.35mins (approximately)

SEE THE IMPROVEMENT from 101 mins to 20.35 mins (BETTER APPROACH)

3) PARALLEL - lets say organizers get some extra funds and thus decided to invite two professional champion player (both equally capable) and divided the set of same 10 players (challengers) in two group of 5 each and assigned them to two champion i.e. one group each. Now the event is progressing in parallel in these two sets i.e. at least two players (one in each group) are playing against the two professional players in their respective group.

However within the group the professional player with take one player at a time (i.e. sequentially) so without any calculation you can easily deduce that whole event will approximately complete in 101/2=50.5mins to complete

SEE THE IMPROVEMENT from 101 mins to 50.5 mins (GOOD APPROACH)

4) CONCURRENT + PARALLEL - In above scenario, lets say that the two champion player will play concurrently (read 2nd point) with the 5 players in their respective groups so now games across groups are running in parallel but within group they are running concurrently.

So the games in one group will approximately complete in 11xtime_per_turn_by_player_&_champion + 11xtransition_time_across_5_players = 11x51 + 11x30 = 600 + 330 = 930sec = 15.5mins (approximately)

So the whole event (involving two such parallel running group) will approximately complete in 15.5mins

SEE THE IMPROVEMENT from 101 mins to 15.5 mins (BEST APPROACH)

NOTE: in above scenario if you replace 10 players with 10 similar jobs and two professional player with a two CPU cores then again the following ordering will remain true:

SERIAL > PARALLEL > CONCURRENT > CONCURRENT+PARALLEL

(NOTE: this order might change for other scenarios as this ordering highly depends on inter-dependency of jobs, communication needs b/w jobs and transition overhead b/w jobs)

I know this is an old thread but thought I should mention that the extern keyword. I've recently ran into this issue and solved as follows

Helper.h

namespace DX
{
    extern inline void ThrowIfFailed(HRESULT hr);
}

Helper.cpp

namespace DX
{
    inline void ThrowIfFailed(HRESULT hr)
    {
        if (FAILED(hr))
        {
            std::stringstream ss;
            ss << "#" << hr;
            throw std::exception(ss.str().c_str());
        }
    }
}

Use RXTX.

On Debian install librxtx-java by typing:

sudo apt-get install librxtx-java

On Fedora or Enterprise Linux install rxtx by typing:

sudo yum install rxtx

I too faced same issue and following steps in resolution of this.

1. I removed unnecessary python path from system except anaconda path.
2. C:\Users<user-Name>\AppData\Roaming<python> = remove any unnecessary python files /folder. these files may interfere with current execution.

If the default behavior (example.com/?p=42) is working, you should:

• Change to your preferred permalink style: Admin: Settings > Permalinks, and click Save. Sometime it fixes the issue. If it didn't:
• Verify that the file /path/to/wordpress/.htaccess has been changed and now includes the line RewriteEngine On. If it doesn't include the line, it's a Wordpress permissions issue.

• Verify that the 'rewrite' module is loaded: create a PHP file with

  <?php
    phpinfo()
  ?>
  

  in it, open it in the browser and search for mod_rewrite. It should be in the 'Loaded Modules' section. If it's not, enable it - Look at your apache default index.html file for details - in Ubuntu, you do it with the helper a2enmod.

• Verify that apache server is looking at the .htaccess file. open httpd.conf - or it's Ubuntu's alternative, /etc/apache2/apache2.conf. In it, You should have something like

  <Directory /path/to/wordpress>
    Options Indexes FollowSymLinks
    AllowOverride All
    Require all granted
  </Directory>
  

• After making these changes, don't forget to restart your apache server. sudo service apache2 restart

I solved the issue by opening up the properties on the exe-file itself. On the tab Compatibility there's a check box for privilege level that says "Run this as an administrator"

Even though my account have administration privileges it didn't work when I started it from task scheduler.

I unchecked the box and started it from the scheduler again and it worked.

In asp.net core, If your api controller doesn't have annotation called [AllowAnonymous], add it to above your controller name like

[ApiController]
    [Route("api/")]
    [AllowAnonymous]
    public class TestController : ControllerBase

in python 3.6 and newer, you can format it just like this:

new_string = f'{s} {i}'
print(new_string)

or just:

print(f'{s} {i}')

1.) First off, what is the correct terminology for an array created on the end of the name element of an input tag in a form?

"Oftimes Confusing PHPism"

As far as JavaScript is concerned a bunch of form controls with the same name are just a bunch of form controls with the same name, and form controls with names that include square brackets are just form controls with names that include square brackets.

The PHP naming convention for form controls with the same name is sometimes useful (when you have a number of groups of controls so you can do things like this:

<input name="name[1]">
<input name="email[1]">
<input name="sex[1]" type="radio" value="m">
<input name="sex[1]" type="radio" value="f">

<input name="name[2]">
<input name="email[2]">
<input name="sex[2]" type="radio" value="m">
<input name="sex[2]" type="radio" value="f">

) but does confuse some people. Some other languages have adopted the convention since this was originally written, but generally only as an optional feature. For example, via this module for JavaScript.

2.) How do I get the information from that array with JavaScript?

It is still just a matter of getting the property with the same name as the form control from elements. The trick is that since the name of the form controls includes square brackets, you can't use dot notation and have to use square bracket notation just like any other JavaScript property name that includes special characters.

Since you have multiple elements with that name, it will be a collection rather then a single control, so you can loop over it with a standard for loop that makes use of its length property.

var myForm = document.forms.id_of_form;
var myControls = myForm.elements['p_id[]'];
for (var i = 0; i < myControls.length; i++) {
    var aControl = myControls[i];
}

This is what I use:

import os, sys
sys.path.append(os.path.join(os.path.dirname(__file__), "lib"))

You can also try /etc/redhat-release or /etc/fedora-release:

cat /etc/fedora-release 
Fedora release 7 (Moonshine)

Try this, I work myself to do so

\i 'somedir\\script2.sql'

Adding my piece of experience. I spent hours trying to find why I had CORS error.

It happens that I've renamed my cloud function (the very first I was trying after a big upgrade).

So when my firebase app was calling the cloud function with an incorrect name, it should have thrown a 404 error, not a CORS error.

Fixing the cloud function name in my firebase app fixed the issue.

I've filled a bug report about this here https://firebase.google.com/support/troubleshooter/report/bugs

For me its now :

docker restart $(docker ps -a -q)

Regarding your second question, generally you don't need to use pointers while programming, however there is one exception to this and that is when you make a public API.

The problem with C++ constructs that people generally use to replace pointers are very dependent on the toolset that you use which is fine when you have all the control you need over the source code, however if you compile a static library with visual studio 2008 for instance and try to use it in a visual studio 2010 you will get a ton of linker errors because the new project is linked with a newer version of STL which is not backwards compatible. Things get even nastier if you compile a DLL and give an import library that people use in a different toolset because in that case your program will crash sooner or later for no apparent reason.

So for the purpose of moving large data sets from one library to another you could consider giving a pointer to an array to the function that is supposed to copy the data if you don't want to force others to use the same tools that you use. The good part about this is that it doesn't even have to be a C-style array, you can use a std::vector and give the pointer by giving the address of the first element &vector[0] for instance, and use the std::vector to manage the array internally.

Another good reason to use pointers in C++ again relates to libraries, consider having a dll that cannot be loaded when your program runs, so if you use an import library then the dependency isn't satisfied and the program crashes. This is the case for instance when you give a public api in a dll alongside your application and you want to access it from other applications. In this case in order to use the API you need to load the dll from its' location (usually it's in a registry key) and then you need to use a function pointer to be able to call functions inside the DLL. Sometimes the people that make the API are nice enough to give you a .h file that contain helper functions to automate this process and give you all the function pointers that you need, but if not you can use LoadLibrary and GetProcAddress on windows and dlopen and dlsym on unix to get them (considering that you know the entire signature of the function).

1. To closed ideas,
2. To remove all folder and file C:/Users/UserName/.m2/org/*,
3. Open ideas and update Maven project,(right click on project -> maven->update maven project)
4. After that update the project.

Here is the way works for me.

From Perl HowTo, the most common ways to execute external commands from Perl are:

• my $files = `ls -la` — captures the output of the command in $files
• system "touch ~/foo" — if you don't want to capture the command's output
• exec "vim ~/foo" — if you don't want to return to the script after executing the command
• open(my $file, '|-', "grep foo"); print $file "foo\nbar" — if you want to pipe input into the command

Change your markup slightly:

$(function() {_x000D_
  enable_cb();_x000D_
  $("#group1").click(enable_cb);_x000D_
});_x000D_
_x000D_
function enable_cb() {_x000D_
  if (this.checked) {_x000D_
    $("input.group1").removeAttr("disabled");_x000D_
  } else {_x000D_
    $("input.group1").attr("disabled", true);_x000D_
  }_x000D_
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
<form name="frmChkForm" id="frmChkForm">_x000D_
  <input type="checkbox" name="chkcc9" id="group1">Check Me <br>_x000D_
  <input type="checkbox" name="chk9[120]" class="group1"><br>_x000D_
  <input type="checkbox" name="chk9[140]" class="group1"><br>_x000D_
  <input type="checkbox" name="chk9[150]" class="group1"><br>_x000D_
</form>

You can do this using attribute selectors without introducing the ID and classes but it's slower and (imho) harder to read.

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.waist2height); {
        final EditText edit = (EditText)findViewById(R.id.editText);          
        final RadioButton rb1 = (RadioButton) findViewById(R.id.radioCM);
        final RadioButton rb2 = (RadioButton) findViewById(R.id.radioFT);                       
        if(rb1.isChecked()){    
            edit.setVisibility(View.VISIBLE);              
        }
        else if(rb2.isChecked()){               
            edit.setVisibility(View.INVISIBLE);
        }
}

You can use a little bit of Javascript to add and remove CSS classes of your navitems. For starters, create a CSS class that you're going to apply to the active element, name it ie: ".activeItem". Then, put a javascript function to each of your navigation buttons' onclick event which is going to add "activeItem" class to the one activated, and remove from the others...

It should look something like this: (untested!)

/*In your stylesheet*/
.activeItem{
   background-color:#999; /*make some difference for the active item here */
}


/*In your javascript*/
var prevItem = null;
function activateItem(t){
   if(prevItem != null){
      prevItem.className = prevItem.className.replace(/{\b}?activeItem/, "");
   }
   t.className += " activeItem";
   prevItem = t;
}

<!-- And then your markup -->
<div id='nav'>
<a href='#abouts' onClick="activateItem(this)">
<div class='navitem about'>
about
</div>
</a>
<a href='#workss' onClick="activateItem(this)">
<div class='navitem works'>
works
</div>
</a>
</div>

My solution:

1. on polymer raise an event (eg. complete)
2. define a directive linking the event to control function

Directive

/*global define */
define(['angular', './my-module'], function(angular, directives) {
    'use strict';
    directives.directive('polimerBinding', ['$compile', function($compile) {

            return {
                 restrict: 'A',
                scope: { 
                    method:'&polimerBinding'
                },
                link : function(scope, element, attrs) {
                    var el = element[0];
                    var expressionHandler = scope.method();
                    var siemEvent = attrs['polimerEvent'];
                    if (!siemEvent) {
                        siemEvent = 'complete';
                    }
                    el.addEventListener(siemEvent, function (e, options) {
                        expressionHandler(e.detail);
                    })
                }
            };
        }]);
});

Here's an old discussion thread where I listed the main differences and the conditions in which you should use each of these methods. I think you may find it useful to go through the discussion.

To explain the differences as relevant to your posted example:

a. When you use RegisterStartupScript, it will render your script after all the elements in the page (right before the form's end tag). This enables the script to call or reference page elements without the possibility of it not finding them in the Page's DOM.

Here is the rendered source of the page when you invoke the RegisterStartupScript method:

<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1"><title></title></head>
<body>
    <form name="form1" method="post" action="StartupScript.aspx" id="form1">
        <div>
            <input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="someViewstategibberish" />
        </div>
        <div> <span id="lblDisplayDate">Label</span>
            <br />
            <input type="submit" name="btnPostback" value="Register Startup Script" id="btnPostback" />
            <br />
            <input type="submit" name="btnPostBack2" value="Register" id="btnPostBack2" />
        </div>
        <div>
            <input type="hidden" name="__EVENTVALIDATION" id="__EVENTVALIDATION" value="someViewstategibberish" />
        </div>
        <!-- Note this part -->
        <script language='javascript'>
            var lbl = document.getElementById('lblDisplayDate');
            lbl.style.color = 'red';
        </script>
    </form>
    <!-- Note this part -->
</body>
</html>

b. When you use RegisterClientScriptBlock, the script is rendered right after the Viewstate tag, but before any of the page elements. Since this is a direct script (not a function that can be called, it will immediately be executed by the browser. But the browser does not find the label in the Page's DOM at this stage and hence you should receive an "Object not found" error.

Here is the rendered source of the page when you invoke the RegisterClientScriptBlock method:

<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1"><title></title></head>
<body>
    <form name="form1" method="post" action="StartupScript.aspx" id="form1">
        <div>
            <input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="someViewstategibberish" />
        </div>
        <script language='javascript'>
            var lbl = document.getElementById('lblDisplayDate');
            // Error is thrown in the next line because lbl is null.
            lbl.style.color = 'green';

Therefore, to summarize, you should call the latter method if you intend to render a function definition. You can then render the call to that function using the former method (or add a client side attribute).

Edit after comments:

For instance, the following function would work:

protected void btnPostBack2_Click(object sender, EventArgs e) 
{ 
  System.Text.StringBuilder sb = new System.Text.StringBuilder(); 
  sb.Append("<script language='javascript'>function ChangeColor() {"); 
  sb.Append("var lbl = document.getElementById('lblDisplayDate');"); 
  sb.Append("lbl.style.color='green';"); 
  sb.Append("}</script>"); 

  //Render the function definition. 
  if (!ClientScript.IsClientScriptBlockRegistered("JSScriptBlock")) 
  {
    ClientScript.RegisterClientScriptBlock(this.GetType(), "JSScriptBlock", sb.ToString()); 
  }

  //Render the function invocation. 
  string funcCall = "<script language='javascript'>ChangeColor();</script>"; 

  if (!ClientScript.IsStartupScriptRegistered("JSScript"))
  { 
    ClientScript.RegisterStartupScript(this.GetType(), "JSScript", funcCall); 
  } 
} 

In case you are trying to use xclip on remote host just add -X to your ssh command

ssh user@host -X

I had a similar problem, not exactly the same conditions and then i saw this post. Hope it helps someone. Apparently i was using one of my EF entity models a base class for a type that was not specified as a db set in my dbcontext. To fix this issue i had to create a base class that had all the properties common to the two types and inherit from the new base class among the two types.

Example:

//Bad Flow
    //class defined in dbcontext as a dbset
    public class Customer{ 
       public int Id {get; set;}
       public string Name {get; set;}
    }

    //class not defined in dbcontext as a dbset
    public class DuplicateCustomer:Customer{ 
       public object DuplicateId {get; set;}
    }


    //Good/Correct flow*
    //Common base class
    public class CustomerBase{ 
       public int Id {get; set;}
       public string Name {get; set;}
    }

    //entity model referenced in dbcontext as a dbset
    public class Customer: CustomerBase{

    }

    //entity model not referenced in dbcontext as a dbset
    public class DuplicateCustomer:CustomerBase{

       public object DuplicateId {get; set;}

    }

It is working with me in Oracle sql developer

    SELECT add_months(trunc(sysdate,'mm'), -1),
           last_day(add_months(trunc(sysdate,'mm'), -1)) 
    FROM dual

var table=document.getElementById("mytab1");_x000D_
var r=0; //start counting rows in table_x000D_
while(row=table.rows[r++])_x000D_
{_x000D_
  var c=0; //start counting columns in row_x000D_
  while(cell=row.cells[c++])_x000D_
  {_x000D_
    cell.innerHTML='[R'+r+'C'+c+']'; // do sth with cell_x000D_
  }_x000D_
}

<table id="mytab1">_x000D_
  <tr>_x000D_
    <td>A1</td><td>A2</td><td>A3</td>_x000D_
  </tr>_x000D_
  <tr>_x000D_
    <td>B1</td><td>B2</td><td>B3</td>_x000D_
  </tr>_x000D_
  <tr>_x000D_
    <td>C1</td><td>C2</td><td>C3</td>_x000D_
  </tr>_x000D_
</table>

In each pass through while loop r/c iterator increases and new row/cell object from collection is assigned to row/cell variables. When there's no more rows/cells in collection, false is assigned to row/cell variable and iteration through while loop stops (exits).

The WordPress password hasher implements the Portable PHP password hashing framework, which is used in Content Management Systems like WordPress and Drupal.

They used to use MD5 in the older versions, but sadly for me, no more. You can generate hashes using this encryption scheme at http://scriptserver.mainframe8.com/wordpress_password_hasher.php.

Do you want to find the length of the string in python language ? If you want to find the length of the word, you can use the len function.

string = input("Enter the string : ")

print("The string length is : ",len(string))

OUTPUT : -

Enter the string : viral

The string length is : 5

Say suppose, you have

File f  = new File("SomeFile");
f.length();

You need not close the Files, because its just the representation of a path.

You should always consider to close only reader/writers and in fact streams.

You can use:

return View("../Category/NotFound", model);

It was tested in ASP.NET MVC 3, but should also work in ASP.NET MVC 2.

Use

ax.xaxis.tick_top()

to place the tick marks at the top of the image. The command

ax.set_xlabel('X LABEL')    
ax.xaxis.set_label_position('top') 

affects the label, not the tick marks.

There is an Oracle article I found regarding Java 9 module system

By default, a type in a module is not accessible to other modules unless it’s a public type and you export its package. You expose only the packages you want to expose. With Java 9, this also applies to reflection.

As pointed out in https://stackoverflow.com/a/50251958/134894, the differences between the AccessibleObject#setAccessible for JDK8 and JDK9 are instructive. Specifically, JDK9 added

This method may be used by a caller in class C to enable access to a member of declaring class D if any of the following hold:

• C and D are in the same module.
• The member is public and D is public in a package that the module containing D exports to at least the module containing C.
• The member is protected static, D is public in a package that the module containing D exports to at least the module containing C, and C is a subclass of D.
• D is in a package that the module containing D opens to at least the module containing C. All packages in unnamed and open modules are open to all modules and so this method always succeeds when D is in an unnamed or open module.

which highlights the significance of modules and their exports (in Java 9)

You must use one of the following ways:

    string s = @"loooooooooooooooooooooooong loooooong
                  long long long";

string s = "loooooooooong loooong" +
           " long long" ;

For me I had to go in here:

%userprofile%\.nuget\packages

You should enable your interceptor extension man manually, it locate in the top-right of your postman window. There are several buttons, find the interceptor button and enable it, then you can send cookies after set Cookie field in your request headers.

mkdirs() also creates parent directories in the path this File represents.

javadocs for mkdirs():

Creates the directory named by this abstract pathname, including any necessary but nonexistent parent directories. Note that if this operation fails it may have succeeded in creating some of the necessary parent directories.

javadocs for mkdir():

Creates the directory named by this abstract pathname.

Example:

File  f = new File("non_existing_dir/someDir");
System.out.println(f.mkdir());
System.out.println(f.mkdirs());

will yield false for the first [and no dir will be created], and true for the second, and you will have created non_existing_dir/someDir

setTimeout():

It is a function that execute a JavaScript statement AFTER x interval.

setTimeout(function () {
    something();
}, 1000); // Execute something() 1 second later.

setInterval():

It is a function that execute a JavaScript statement EVERY x interval.

setInterval(function () {
    somethingElse();
}, 2000); // Execute somethingElse() every 2 seconds.

The interval unit is in millisecond for both functions.

This should work:

 cat "$API" >> "$CONFIG"

You need to use the >> operator to append to a file. Redirecting with > causes the file to be overwritten. (truncated).

Type this to B3, and then pull it to the rest of the rows:

=IF(C3=C2,B2,B2+COUNTIF($C$1:$C3,C2))

What it does is:

• If my points equals the previous points, I have the same position.
• Othewise count the players with the same score as the previous one, and add their numbers to the previous player's position.

In versions of Gradle prior to 5, the test.single system property can be used to specify a single test.

You can do gradle -Dtest.single=ClassUnderTestTest test if you want to test single class or use regexp like gradle -Dtest.single=ClassName*Test test you can find more examples of filtering classes for tests under this link.

Gradle 5 removed this option, as it was superseded by test filtering using the --tests command line option.

you can easily access elements by index , by use System.Linq

Here is the sample

First add using in your class file

using System.Linq;

Then

yourDictionaryData.ElementAt(i).Key
yourDictionaryData.ElementAt(i).Value

Hope this helps.

You can create an icon using this website https://romannurik.github.io/AndroidAssetStudio/index.html.

Download the icon, go to File Explorer - where your projects are saved, the default path is C:\Users\Your Name\AndroidStudioProjects\Project Name\app\src\main\res\

and copy the folders you downloaded to the res folder.

It cannot be done. It is impossible.

An example, just to make this a 15 seconds answer -

Say you have "styles.xaml" in a WPF library named "common" and you want to use it from your main application project:

1. Add a reference from the main project to "common" project
2. Your app.xaml should contain:

<Application.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="pack://application:,,,/Common;component/styles.xaml"/>
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
</Application.Resources>

As i can see you already got lots of answer but you can try this method to .

Its best practice not to use jquery in angular, I prefer https://github.com/valor-software/ngx-bootstrap/blob/development/docs/getting-started/ng-cli.md method to install bootstrap without using bootstrap js component which depends on jquery.

npm install ngx-bootstrap bootstrap --save

or

ng add ngx-bootstrap   (Preferred)

Keep your code jquery free in angular

think simple

<button id="button1" onclick="Click();">ok</button>
<script>
    var buttonClick = false;
    function Click() {
        if (buttonClick) {
            return;
        }
        else {
            buttonClick = true;
            //todo
            alert("ok");
            //buttonClick = false;
        }
    }
</script>

if you want run once :)

You are looking for -H option in gnu grep.

find . -name '*bills*' -exec grep -H "put" {} \;

Here is the explanation

    -H, --with-filename
      Print the filename for each match.

Most answers here will work fine if you have just two conditions in your if-else. For more which is I guess what you want, you'll be using arrays. Every names corresponding element in names array you'll have an element in the hasNames array with the exact same index. Then it's a matter of these four lines.

names = "true";
var names = ["true","false","1","2"];
var hasNames = ["Y","N","true","false"];
var intIndex = names.indexOf(name);
hasName = hasNames[intIndex ];

This method could also be implemented using Objects and properties as illustrated by Benjamin.

Asp.net is pretty good at automatically converting .net objects to json. Your List object if returned in your webmethod should return a json/javascript array. What I mean by this is that you shouldn't change the return type to string (because that's what you think the client is expecting) when returning data from a method. If you return a .net array from a webmethod a javaScript array will be returned to the client. It doesn't actually work too well for more complicated objects, but for simple array data its fine.

Of course, it's then up to you to do what you need to do on the client side.

I would be thinking something like this:

[WebMethod]
public static List GetProducts()
{
   var products  = context.GetProducts().ToList();   
   return products;
}

There shouldn't really be any need to initialise any custom converters unless your data is more complicated than simple row/col data

As already said, the easiest way is to use querystring.

But if you cannot, because of security reason, you should consider using cookies.

Adding a few more points to Jason's Answer :

For taking all user provided arguments : user_args = sys.argv[1:]

Consider the sys.argv as a list of strings as (mentioned by Jason). So all the list manipulations will apply here. This is called "List Slicing". For more info visit here.

The syntax is like this : list[start:end:step]. If you omit start, it will default to 0, and if you omit end, it will default to length of list.

Suppose you only want to take all the arguments after 3rd argument, then :

user_args = sys.argv[3:]

Suppose you only want the first two arguments, then :

user_args = sys.argv[0:2]  or  user_args = sys.argv[:2]

Suppose you want arguments 2 to 4 :

user_args = sys.argv[2:4]

Suppose you want the last argument (last argument is always -1, so what is happening here is we start the count from back. So start is last, no end, no step) :

user_args = sys.argv[-1]

Suppose you want the second last argument :

user_args = sys.argv[-2]

Suppose you want the last two arguments :

user_args = sys.argv[-2:]

Suppose you want the last two arguments. Here, start is -2, that is second last item and then to the end (denoted by ":") :

user_args = sys.argv[-2:]

Suppose you want the everything except last two arguments. Here, start is 0 (by default), and end is second last item :

user_args = sys.argv[:-2]

Suppose you want the arguments in reverse order :

user_args = sys.argv[::-1]

Hope this helps.

If those commands don't seems to work -- I assure you they do --, check the top of your sql dump file for the use of :

CREATE DATABASE {mydbname}

and

USE {mydbname}

The last parameter {mydbname} of the mysql command can be misleading : if CREATE DATABASE an USE are in your dump file, the import will in fact be done in this database, not in the one in the mysql command.

The mysqldump command that will prompt CREATE DATABASE and USE is :

mysqldump.exe -h localhost -u root --databases xxx > xxx.sql

Use mysqldump without --databases to leave out CREATE DATABASE and USE :

mysqldump.exe -h localhost -u root xxx > xxx.sql

v4l support has been dropped in recent kernel versions (including the one shipped with Ubuntu 11.04).

EDIT: Your question is connected to a recent message that was sent to the OpenCV users group, which has instructions to compile OpenCV 2.2 in Ubuntu 11.04. Your approach is not ideal.

To fix that, this works for me like a charm.

ALTER DATABASE dbname CHARACTER SET utf8 COLLATE utf8_general_ci;

The font sizes in your question are an example of what ratio each header should be in comparison to each other, rather than what size they should be themselves (in pixels).

So in response to your question "Is there a 'best practice' for these for mobile phones? - say iphone screen size?", yes there probably is - but you might find what someone says is "best practice" does not work for your layout.

However, to help get you on the right track, this article about building responsive layouts provides a good example of how to calculate the base font-size in pixels in relation to device screen sizes.

The suggested font-sizes for screen resolutions suggested from that article are as follows:

@media (min-width: 858px) {
    html {
        font-size: 12px;
    }
}

@media (min-width: 780px) {
    html {
        font-size: 11px;
    }
}

@media (min-width: 702px) {
    html {
        font-size: 10px;
    }
}

@media (min-width: 724px) {
    html {
        font-size: 9px;
    }
}

@media (max-width: 623px) {
    html {
        font-size: 8px;
    }
}

Use word: using. A good habit of programming.

using (TcpClient tcpClient = new TcpClient())
{
     //operations
     tcpClient.Close();
}

SQL Server:

select * from table
except
select top N * from table

Oracle up to 11.2:

select * from table
minus
select * from table where rownum <= N

with TableWithNum as (
    select t.*, rownum as Num
    from Table t
)
select * from TableWithNum where Num > N

Oracle 12.1 and later (following standard ANSI SQL)

select *
from table
order by some_column 
offset x rows
fetch first y rows only

They may meet your needs more or less.

There is no direct way to do what you want by SQL. However, it is not a design flaw, in my opinion.

SQL is not supposed to be used like this.

In relational databases, a table represents a relation, which is a set by definition. A set contains unordered elements.

Also, don't rely on the physical order of the records. The row order is not guaranteed by the RDBMS.

If the ordering of the records is important, you'd better add a column such as `Num' to the table, and use the following query. This is more natural.

select * 
from Table 
where Num > N
order by Num

The key is calling the parent's method using super.methodName();

class A {
    // A protected method
    protected doStuff()
    {
        alert("Called from A");
    }

    // Expose the protected method as a public function
    public callDoStuff()
    {
        this.doStuff();
    }
}

class B extends A {

    // Override the protected method
    protected doStuff()
    {
        // If we want we can still explicitly call the initial method
        super.doStuff();
        alert("Called from B");
    }
}

var a = new A();
a.callDoStuff(); // Will only alert "Called from A"

var b = new B()
b.callDoStuff(); // Will alert "Called from A" then "Called from B"

@Simple-Solution

I use a simple Python HTTP server. When in the directory of the Angular app in question (using a MBP with Mavericks 10.9 and Python 2.x) I simply run

python -m SimpleHTTPServer 8080

And that sets up the simple server on port 8080 letting you visit localhost:8080 on your browser to view the app in development.

Hope that helped!

in kotlin its quite easy, using extensions methods of toMediaType, asRequestBody and toRequestBody here's an example:

here I am posting a couple of normal fields along with a pdf file and an image file using multipart

this is API declaration using retrofit:

    @Multipart
    @POST("api/Lesson/AddNewLesson")
    fun createLesson(
        @Part("userId") userId: RequestBody,
        @Part("LessonTitle") lessonTitle: RequestBody,
        @Part pdf: MultipartBody.Part,
        @Part imageFile: MultipartBody.Part
    ): Maybe<BaseResponse<String>>

and here is how to actually call it:

api.createLesson(
            userId.toRequestBody("text/plain".toMediaType()),
            lessonTitle.toRequestBody("text/plain".toMediaType()),
            startFromRegister.toString().toRequestBody("text/plain".toMediaType()),
            MultipartBody.Part.createFormData(
                "jpeg",
                imageFile.name,
                imageFile.asRequestBody("image/*".toMediaType())
            ),
            MultipartBody.Part.createFormData(
                "pdf",
                pdfFile.name,
                pdfFile.asRequestBody("application/pdf".toMediaType())
            )

The problem may be that ssh is trying to connect to all the different IPs that www.google.com resolves to. For example on my machine:

# ssh -v -o ConnectTimeout=1 -o ConnectionAttempts=1 www.google.com
OpenSSH_5.9p1, OpenSSL 0.9.8t 18 Jan 2012
debug1: Connecting to www.google.com [173.194.43.20] port 22.
debug1: connect to address 173.194.43.20 port 22: Connection timed out
debug1: Connecting to www.google.com [173.194.43.19] port 22.
debug1: connect to address 173.194.43.19 port 22: Connection timed out
debug1: Connecting to www.google.com [173.194.43.18] port 22.
debug1: connect to address 173.194.43.18 port 22: Connection timed out
debug1: Connecting to www.google.com [173.194.43.17] port 22.
debug1: connect to address 173.194.43.17 port 22: Connection timed out
debug1: Connecting to www.google.com [173.194.43.16] port 22.
debug1: connect to address 173.194.43.16 port 22: Connection timed out
ssh: connect to host www.google.com port 22: Connection timed out

If I run it with a specific IP, it returns much faster.

EDIT: I've timed it (with time) and the results are:

• www.google.com - 5.086 seconds
• 173.94.43.16 - 1.054 seconds

path.resolve('.') is also a reliable and clean option, because we almost always require('path'). It will give you absolute path of the directory from where it is called.

Wouldn't it be better to not use any dynamic types for this, and let your class implement an interface. Then, you can check at runtime wether an object implements that interface, and thus, has the expected method (or property).

public interface IMyInterface
{
   void Somemethod();
}


IMyInterface x = anyObject as IMyInterface;
if( x != null )
{
   x.Somemethod();
}

I think this is the only correct way.

The thing you're referring to is duck-typing, which is useful in scenarios where you already know that the object has the method, but the compiler cannot check for that. This is useful in COM interop scenarios for instance. (check this article)

If you want to combine duck-typing with reflection for instance, then I think you're missing the goal of duck-typing.

Here is the solutions that worked for me:

1. open index.php from the htdocs folder
2. inside replace the word dashboard with your database name.
3. restart the server

This should resolve the issue :-)

OrElse is the short-circuited equivalent of Or

To get the value of my drop down box on page load, I use

Hope this helps some one.

TypeError: Cannot read property 'then' of undefined when calling a Django service using AngularJS.

If you are calling a Python service, the code will look like below:

this.updateTalentSupplier=function(supplierObj){
  var promise = $http({
    method: 'POST',
      url: bbConfig.BWS+'updateTalentSupplier/',
      data:supplierObj,
      withCredentials: false,
      contentType:'application/json',
      dataType:'json'
    });
    return promise; //Promise is returned 
}

We are using MongoDB as the database(I know it doesn't matter. But if someone is searching with MongoDB + Python (Django) + AngularJS the result should come.

UPDATE: 9/24/16 Angular 2.0 Stable

This question gets a lot of traffic still, so, I wanted to update it. With the insanity of changes from Alpha, Beta, and 7 RC candidates, I stopped updating my SO answers until they went stable.

This is the perfect case for using Subjects and ReplaySubjects

I personally prefer to use ReplaySubject(1) as it allows the last stored value to be passed when new subscribers attach even when late:

let project = new ReplaySubject(1);

//subscribe
project.subscribe(result => console.log('Subscription Streaming:', result));

http.get('path/to/whatever/projects/1234').subscribe(result => {
    //push onto subject
    project.next(result));

    //add delayed subscription AFTER loaded
    setTimeout(()=> project.subscribe(result => console.log('Delayed Stream:', result)), 3000);
});

//Output
//Subscription Streaming: 1234
//*After load and delay*
//Delayed Stream: 1234

So even if I attach late or need to load later I can always get the latest call and not worry about missing the callback.

This also lets you use the same stream to push down onto:

project.next(5678);
//output
//Subscription Streaming: 5678

But what if you are 100% sure, that you only need to do the call once? Leaving open subjects and observables isn't good but there's always that "What If?"

That's where AsyncSubject comes in.

let project = new AsyncSubject();

//subscribe
project.subscribe(result => console.log('Subscription Streaming:', result),
                  err => console.log(err),
                  () => console.log('Completed'));

http.get('path/to/whatever/projects/1234').subscribe(result => {
    //push onto subject and complete
    project.next(result));
    project.complete();

    //add a subscription even though completed
    setTimeout(() => project.subscribe(project => console.log('Delayed Sub:', project)), 2000);
});

//Output
//Subscription Streaming: 1234
//Completed
//*After delay and completed*
//Delayed Sub: 1234

Awesome! Even though we closed the subject it still replied with the last thing it loaded.

Another thing is how we subscribed to that http call and handled the response. Map is great to process the response.

public call = http.get(whatever).map(res => res.json())

But what if we needed to nest those calls? Yes you could use subjects with a special function:

getThing() {
    resultSubject = new ReplaySubject(1);

    http.get('path').subscribe(result1 => {
        http.get('other/path/' + result1).get.subscribe(response2 => {
            http.get('another/' + response2).subscribe(res3 => resultSubject.next(res3))
        })
    })
    return resultSubject;
}
var myThing = getThing();

But that's a lot and means you need a function to do it. Enter FlatMap:

var myThing = http.get('path').flatMap(result1 => 
                    http.get('other/' + result1).flatMap(response2 => 
                        http.get('another/' + response2)));

Sweet, the var is an observable that gets the data from the final http call.

OK thats great but I want an angular2 service!

I got you:

import { Injectable } from '@angular/core';
import { Http, Response } from '@angular/http';
import { ReplaySubject } from 'rxjs';

@Injectable()
export class ProjectService {

  public activeProject:ReplaySubject<any> = new ReplaySubject(1);

  constructor(private http: Http) {}

  //load the project
  public load(projectId) {
    console.log('Loading Project:' + projectId, Date.now());
    this.http.get('/projects/' + projectId).subscribe(res => this.activeProject.next(res));
    return this.activeProject;
  }

 }

 //component

@Component({
    selector: 'nav',
    template: `<div>{{project?.name}}<a (click)="load('1234')">Load 1234</a></div>`
})
 export class navComponent implements OnInit {
    public project:any;

    constructor(private projectService:ProjectService) {}

    ngOnInit() {
        this.projectService.activeProject.subscribe(active => this.project = active);
    }

    public load(projectId:string) {
        this.projectService.load(projectId);
    }

 }

I'm a big fan of observers and observables so I hope this update helps!

Original Answer

I think this is a use case of using a Observable Subject or in Angular2 the EventEmitter.

In your service you create a EventEmitter that allows you to push values onto it. In Alpha 45 you have to convert it with toRx(), but I know they were working to get rid of that, so in Alpha 46 you may be able to simply return the EvenEmitter.

class EventService {
  _emitter: EventEmitter = new EventEmitter();
  rxEmitter: any;
  constructor() {
    this.rxEmitter = this._emitter.toRx();
  }
  doSomething(data){
    this.rxEmitter.next(data);
  }
}

This way has the single EventEmitter that your different service functions can now push onto.

If you wanted to return an observable directly from a call you could do something like this:

myHttpCall(path) {
    return Observable.create(observer => {
        http.get(path).map(res => res.json()).subscribe((result) => {
            //do something with result. 
            var newResultArray = mySpecialArrayFunction(result);
            observer.next(newResultArray);
            //call complete if you want to close this stream (like a promise)
            observer.complete();
        });
    });
}

That would allow you do this in the component: peopleService.myHttpCall('path').subscribe(people => this.people = people);

And mess with the results from the call in your service.

I like creating the EventEmitter stream on its own in case I need to get access to it from other components, but I could see both ways working...

Here's a plunker that shows a basic service with an event emitter: Plunkr

The reason why you are getting the compilation error is, you are trying to access the session in declaration block (<%! %>) where it is not available. All the implicit objects of jsp are available in service method only. Code of declarative blocks goes outside the service method.

I'd advice you to use EL. It is a simplified approach.

${sessionScope.username} would give you the desired output.

Ambers's solution also works well for numpy arrays:

from pylab import *
import csv

array_=arange(0,10,1)
list_=[array_,array_*2,array_*3]
with open("output.csv", "wb") as f:
    writer = csv.writer(f)
    writer.writerows(list_)

Function In function python

def Greater(a,b):
    if a>b:
        return a
    return b

def Greater_new(a,b,c,d):
    return Greater(Greater(a,b),Greater(c,d))

print("Greater Number is :-",Greater_new(212,33,11,999))

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.

I know all these steps and actually the following is the short and fantastic way.

1 - Go to appengine.google.com, open your app

2 - Administration > Versions > Add Domain... (your domain has to be linked to your Google Apps account, follow the steps to do that including the domain verification.)

3 - Go to www.google.com/a/yourdomain.com

4 - Dashboard > your app should be listed here. Click on it.

5 - myappid settings page > Web address > Add new URL

6 - Simply enter www and click Add

7 - Using your domain hosting provider's web interface, add a CNAME for www for your domain and point to ghs.googlehosted.com

8 - Now you have www.mydomain.com linked to your app.

• If you want naked domain, i.e. mydomain.com, use a redirect un your DNS administrator (not in Google Apps) and point it to www.mydomain.com.

Now that I've done that all, I can go to my appengine app successfully using my custom domain. For example http://cic.mx and http://www.cic.mx both take me to my app. But URL changes to -myappid-.appspot.com and I don't want it to happen !

Has anyone solved this issue?

I'm using a php app on the appengine, with a wordpress instance.

As stated in comments below, you can use also the SET ROWCOUNT clause, but just for SQL Server 2014 and older.

SET ROWCOUNT 10

UPDATE messages
SET status = 10 
WHERE status = 0 

SET ROWCOUNT 0

More info: http://msdn.microsoft.com/en-us/library/ms188774.aspx

Or with a temp table

DECLARE @t TABLE (id INT)
INSERT @t (id)
SELECT TOP 10 id
FROM messages
WHERE status = 0
ORDER BY priority DESC

UPDATE messages
SET status = 10
WHERE id IN (SELECT id FROM @t)

if ($profitloss < 0)
{
   echo "The profitloss is negative";
}

Edit: I feel like this was too simple an answer for the rep so here's something that you may also find helpful.

In PHP we can find the absolute value of an integer by using the abs() function. For example if I were trying to work out the difference between two figures I could do this:

$turnover = 10000;
$overheads = 12500;

$difference = abs($turnover-$overheads);

echo "The Difference is ".$difference;

This would produce The Difference is 2500.

The ggplot2 package takes a little bit of learning, but the results look really nice, you get nice legends, plus many other nice features, all without having to write much code.

require(ggplot2)
require(reshape2)
df <- data.frame(time = 1:10,
                 a = cumsum(rnorm(10)),
                 b = cumsum(rnorm(10)),
                 c = cumsum(rnorm(10)))
df <- melt(df ,  id.vars = 'time', variable.name = 'series')

# plot on same grid, each series colored differently -- 
# good if the series have same scale
ggplot(df, aes(time,value)) + geom_line(aes(colour = series))

# or plot on different plots
ggplot(df, aes(time,value)) + geom_line() + facet_grid(series ~ .)

|= reads the same way as +=.

notification.defaults |= Notification.DEFAULT_SOUND;

is the same as

notification.defaults = notification.defaults | Notification.DEFAULT_SOUND;

where | is the bit-wise OR operator.

All operators are referenced here.

A bit-wise operator is used because, as is frequent, those constants enable an int to carry flags.

If you look at those constants, you'll see that they're in powers of two :

public static final int DEFAULT_SOUND = 1;
public static final int DEFAULT_VIBRATE = 2; // is the same than 1<<1 or 10 in binary
public static final int DEFAULT_LIGHTS = 4; // is the same than 1<<2 or 100 in binary

So you can use bit-wise OR to add flags

int myFlags = DEFAULT_SOUND | DEFAULT_VIBRATE; // same as 001 | 010, producing 011

so

myFlags |= DEFAULT_LIGHTS;

simply means we add a flag.

And symmetrically, we test a flag is set using & :

boolean hasVibrate = (DEFAULT_VIBRATE & myFlags) != 0;

javax.xml.bind.DatatypeConverter should do it:

byte [] b = javax.xml.bind.DatatypeConverter.parseHexBinary("E62DB");
String s = javax.xml.bind.DatatypeConverter.printHexBinary(b);

First, you need to configure your computer to get a static IP from your router. Instructions for how to do this can be found: here

For example, let's say you picked the IP address 192.168.1.102. After the above step is completed, you should be able to get to the website on your local machine by going to both http://localhost and http://192.168.1.102, since your computer will now always have that IP address on your network.

If you look up your IP address (such as http://www.ip-adress.com/), the IP you see is actually the IP of your router. When your friend accesses your website, you'll give him this IP. However, you need to tell your router that when it gets a request for a webpage, forward that request to your server. This is done through port forwarding.

Two examples of how to do this can be found here and here, although the exact screens you see will vary depending on the manufacturer of your router (Google for exact instructions, if needed).

For the Linksys router I have, I enter http://192.168.1.1/, enter my username/password, Applications & Gaming tab > Port Range Forward. Enter the application name (whatever you want to call it), start port (80), end port (80), protocol (TCP), ip address (using the above example, you would enter 192.168.1.102, which is the static IP you assigned your server), and be sure to check to enable the forwarding. Restart your router and the changes should take effect.

Having done all that, your friend should now be able to access your webpage by going to his web browser on his machine and entering http://IP.address.of.your.computer (the same one you see when you go here ).

As mentioned earlier, the IP address assigned to you by your ISP will eventually change whether you sign offline or not. I strongly recommend using DynDns, which is absolutely free. You can choose a hostname at their domain (such as cuga.kicks-ass.net) and your friend can then always access your website by simply going to http://cuga.kicks-ass.net in his browser. Here is their site again: DynDns

I hope this helps.

If you need to store a member function without the class instance, you can do something like this:

class MyClass
{
public:
    void MemberFunc(int value)
    {
      //do something
    }
};

// Store member function binding
auto callable = std::mem_fn(&MyClass::MemberFunc);

// Call with late supplied 'this'
MyClass myInst;
callable(&myInst, 123);

What would the storage type look like without auto? Something like this:

std::_Mem_fn_wrap<void,void (__cdecl TestA::*)(int),TestA,int> callable

You can also pass this function storage to a standard function binding

std::function<void(int)> binding = std::bind(callable, &testA, std::placeholders::_1);
binding(123); // Call

Past and future notes: An older interface std::mem_func existed, but has since been deprecated. A proposal exists, post C++17, to make pointer to member functions callable. This would be most welcome.

You can do that with list comprehension too:

A=[[x*100, x][x % 2 != 0] for x in range(1,11)]
print A

This works in Chrome but not Firefox 3.6 (warning: RickRoll video):

<iframe width="420" height="345" src="http://www.youtube.com/embed/oHg5SJYRHA0?autoplay=1" frameborder="0" allowfullscreen></iframe>

The JavaScript API for iframe embeds exists, but is still posted as an experimental feature.

UPDATE: The iframe API is now fully supported and "Creating YT.Player objects - Example 2" shows how to set "autoplay" in JavaScript.

Here is an example that shows the differences, which will help with the explanation.

var s1 = new String("Avoid newing things where possible");
var s2 = "A string, in TypeScript of type 'string'";
var s3: string;

String is the JavaScript String type, which you could use to create new strings. Nobody does this as in JavaScript the literals are considered better, so s2 in the example above creates a new string without the use of the new keyword and without explicitly using the String object.

string is the TypeScript string type, which you can use to type variables, parameters and return values.

Additional notes...

Currently (Feb 2013) Both s1 and s2 are valid JavaScript. s3 is valid TypeScript.

Use of String. You probably never need to use it, string literals are universally accepted as being the correct way to initialise a string. In JavaScript, it is also considered better to use object literals and array literals too:

var arr = []; // not var arr = new Array();
var obj = {}; // not var obj = new Object();

If you really had a penchant for the string, you could use it in TypeScript in one of two ways...

var str: String = new String("Hello world"); // Uses the JavaScript String object
var str: string = String("Hello World"); // Uses the TypeScript string type

for i in range(100):
try:
  #Your code here
  break
except:
  continue

This one worked for me.

Unload Me only works when its called from userform self. If you want to close a form from another module code (or userform), you need to use the Unload function + userformtoclose name.

I hope its helps

jimmyorr's answer does not work on Windows. it helps to use --not instead of ^ like so:

git log oldbranch --not newbranch --no-merges

If you always want to the same transition animation for the activity

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    overridePendingTransition(android.R.anim.fade_in, android.R.anim.fade_out);

@Override
protected void onPause() {
    super.onPause();
    if (isFinishing()) {
        overridePendingTransition(android.R.anim.fade_in, android.R.anim.fade_out);
    }
}

An Error "indicates serious problems that a reasonable application should not try to catch."

while

An Exception "indicates conditions that a reasonable application might want to catch."

Error along with RuntimeException & their subclasses are unchecked exceptions. All other Exception classes are checked exceptions.

Checked exceptions are generally those from which a program can recover & it might be a good idea to recover from such exceptions programmatically. Examples include FileNotFoundException, ParseException, etc. A programmer is expected to check for these exceptions by using the try-catch block or throw it back to the caller

On the other hand we have unchecked exceptions. These are those exceptions that might not happen if everything is in order, but they do occur. Examples include ArrayIndexOutOfBoundException, ClassCastException, etc. Many applications will use try-catch or throws clause for RuntimeExceptions & their subclasses but from the language perspective it is not required to do so. Do note that recovery from a RuntimeException is generally possible but the guys who designed the class/exception deemed it unnecessary for the end programmer to check for such exceptions.

Errors are also unchecked exception & the programmer is not required to do anything with these. In fact it is a bad idea to use a try-catch clause for Errors. Most often, recovery from an Error is not possible & the program should be allowed to terminate. Examples include OutOfMemoryError, StackOverflowError, etc.

Do note that although Errors are unchecked exceptions, we shouldn't try to deal with them, but it is ok to deal with RuntimeExceptions(also unchecked exceptions) in code. Checked exceptions should be handled by the code.

I was trying to solve the problem of being able to iterate over several different text arrays all of which are stored within a memory resident database that is a large struct.

The following was worked out using Visual Studio 2017 Community Edition on an MFC test application. I am including this as an example as this posting was one of several that I ran across that provided some help yet were still insufficient for my needs.

The struct containing the memory resident data looked something like the following. I have removed most of the elements for the sake of brevity and have also not included the Preprocessor defines used (the SDK in use is for C as well as C++ and is old).

What I was interested in doing is having iterators for the various WCHAR two dimensional arrays which contained text strings for mnemonics.

typedef struct  tagUNINTRAM {
    // stuff deleted ...
    WCHAR   ParaTransMnemo[MAX_TRANSM_NO][PARA_TRANSMNEMO_LEN]; /* prog #20 */
    WCHAR   ParaLeadThru[MAX_LEAD_NO][PARA_LEADTHRU_LEN];   /* prog #21 */
    WCHAR   ParaReportName[MAX_REPO_NO][PARA_REPORTNAME_LEN];   /* prog #22 */
    WCHAR   ParaSpeMnemo[MAX_SPEM_NO][PARA_SPEMNEMO_LEN];   /* prog #23 */
    WCHAR   ParaPCIF[MAX_PCIF_SIZE];            /* prog #39 */
    WCHAR   ParaAdjMnemo[MAX_ADJM_NO][PARA_ADJMNEMO_LEN];   /* prog #46 */
    WCHAR   ParaPrtModi[MAX_PRTMODI_NO][PARA_PRTMODI_LEN];  /* prog #47 */
    WCHAR   ParaMajorDEPT[MAX_MDEPT_NO][PARA_MAJORDEPT_LEN];    /* prog #48 */
    //  ... stuff deleted
} UNINIRAM;

The current approach is to use a template to define a proxy class for each of the arrays and then to have a single iterator class that can be used to iterate over a particular array by using a proxy object representing the array.

A copy of the memory resident data is stored in an object that handles reading and writing the memory resident data from/to disk. This class, CFilePara contains the templated proxy class (MnemonicIteratorDimSize and the sub class from which is it is derived, MnemonicIteratorDimSizeBase) and the iterator class, MnemonicIterator.

The created proxy object is attached to an iterator object which accesses the necessary information through an interface described by a base class from which all of the proxy classes are derived. The result is to have a single type of iterator class which can be used with several different proxy classes because the different proxy classes all expose the same interface, the interface of the proxy base class.

The first thing was to create a set of identifiers which would be provided to a class factory to generate the specific proxy object for that type of mnemonic. These identifiers are used as part of the user interface to identify the particular provisioning data the user is interested in seeing and possibly modifying.

const static DWORD_PTR dwId_TransactionMnemonic = 1;
const static DWORD_PTR dwId_ReportMnemonic = 2;
const static DWORD_PTR dwId_SpecialMnemonic = 3;
const static DWORD_PTR dwId_LeadThroughMnemonic = 4;

The Proxy Class

The templated proxy class and its base class are as follows. I needed to accommodate several different kinds of wchar_t text string arrays. The two dimensional arrays had different numbers of mnemonics, depending on the type (purpose) of the mnemonic and the different types of mnemonics were of different maximum lengths, varying between five text characters and twenty text characters. Templates for the derived proxy class was a natural fit with the template requiring the maximum number of characters in each mnemonic. After the proxy object is created, we then use the SetRange() method to specify the actual mnemonic array and its range.

// proxy object which represents a particular subsection of the
// memory resident database each of which is an array of wchar_t
// text arrays though the number of array elements may vary.
class MnemonicIteratorDimSizeBase
{
    DWORD_PTR  m_Type;

public:
    MnemonicIteratorDimSizeBase(DWORD_PTR x) { }
    virtual ~MnemonicIteratorDimSizeBase() { }

    virtual wchar_t *begin() = 0;
    virtual wchar_t *end() = 0;
    virtual wchar_t *get(int i) = 0;
    virtual int ItemSize() = 0;
    virtual int ItemCount() = 0;

    virtual DWORD_PTR ItemType() { return m_Type; }
};

template <size_t sDimSize>
class MnemonicIteratorDimSize : public MnemonicIteratorDimSizeBase
{
    wchar_t    (*m_begin)[sDimSize];
    wchar_t    (*m_end)[sDimSize];

public:
    MnemonicIteratorDimSize(DWORD_PTR x) : MnemonicIteratorDimSizeBase(x), m_begin(0), m_end(0) { }
    virtual ~MnemonicIteratorDimSize() { }

    virtual wchar_t *begin() { return m_begin[0]; }
    virtual wchar_t *end() { return m_end[0]; }
    virtual wchar_t *get(int i) { return m_begin[i]; }

    virtual int ItemSize() { return sDimSize; }
    virtual int ItemCount() { return m_end - m_begin; }

    void SetRange(wchar_t (*begin)[sDimSize], wchar_t (*end)[sDimSize]) {
        m_begin = begin; m_end = end;
    }

};

The Iterator Class

The iterator class itself is as follows. This class provides just basic forward iterator functionality which is all that is needed at this time. However I expect that this will change or be extended when I need something additional from it.

class MnemonicIterator
{
private:
    MnemonicIteratorDimSizeBase   *m_p;  // we do not own this pointer. we just use it to access current item.
    int      m_index;                    // zero based index of item.
    wchar_t  *m_item;                    // value to be returned.

public:
    MnemonicIterator(MnemonicIteratorDimSizeBase *p) : m_p(p) { }
    ~MnemonicIterator() { }

    // a ranged for needs begin() and end() to determine the range.
    // the range is up to but not including what end() returns.
    MnemonicIterator & begin() { m_item = m_p->get(m_index = 0); return *this; }                 // begining of range of values for ranged for. first item
    MnemonicIterator & end() { m_item = m_p->get(m_index = m_p->ItemCount()); return *this; }    // end of range of values for ranged for. item after last item.
    MnemonicIterator & operator ++ () { m_item = m_p->get(++m_index); return *this; }            // prefix increment, ++p
    MnemonicIterator & operator ++ (int i) { m_item = m_p->get(m_index++); return *this; }       // postfix increment, p++
    bool operator != (MnemonicIterator &p) { return **this != *p; }                              // minimum logical operator is not equal to
    wchar_t * operator *() const { return m_item; }                                              // dereference iterator to get what is pointed to
};

The proxy object factory determines which object to created based on the mnemonic identifier. The proxy object is created and the pointer returned is the standard base class type so as to have a uniform interface regardless of which of the different mnemonic sections are being accessed. The SetRange() method is used to specify to the proxy object the specific array elements the proxy represents and the range of the array elements.

CFilePara::MnemonicIteratorDimSizeBase * CFilePara::MakeIterator(DWORD_PTR x)
{
    CFilePara::MnemonicIteratorDimSizeBase  *mi = nullptr;

    switch (x) {
    case dwId_TransactionMnemonic:
        {
            CFilePara::MnemonicIteratorDimSize<PARA_TRANSMNEMO_LEN> *mk = new CFilePara::MnemonicIteratorDimSize<PARA_TRANSMNEMO_LEN>(x);
            mk->SetRange(&m_Para.ParaTransMnemo[0], &m_Para.ParaTransMnemo[MAX_TRANSM_NO]);
            mi = mk;
        }
        break;

Using the Proxy Class and Iterator

The proxy class and its iterator are used as shown in the following loop to fill in a CListCtrl object with a list of mnemonics. I am using std::unique_ptr so that when the proxy class i not longer needed and the std::unique_ptr goes out of scope, the memory will be cleaned up.

What this source code does is to create a proxy object for the array within the struct which corresponds to the specified mnemonic identifier. It then creates an iterator for that object, uses a ranged for to fill in the CListCtrl control and then cleans up. These are all raw wchar_t text strings which may be exactly the number of array elements so we copy the string into a temporary buffer in order to ensure that the text is zero terminated.

    std::unique_ptr<CFilePara::MnemonicIteratorDimSizeBase> pObj(pFile->MakeIterator(m_IteratorType));
    CFilePara::MnemonicIterator pIter(pObj.get());  // provide the raw pointer to the iterator who doesn't own it.

    int i = 0;    // CListCtrl index for zero based position to insert mnemonic.
    for (auto x : pIter)
    {
        WCHAR szText[32] = { 0 };     // Temporary buffer.

        wcsncpy_s(szText, 32, x, pObj->ItemSize());
        m_mnemonicList.InsertItem(i, szText);  i++;
    }

For future reference you can work out computed styles via an inspector

UPDATE
From v0.20, melt is a first order function, you can now use

df.melt(id_vars=["location", "name"], 
        var_name="Date", 
        value_name="Value")

  location    name        Date  Value
0        A  "test"    Jan-2010     12
1        B   "foo"    Jan-2010     18
2        A  "test"    Feb-2010     20
3        B   "foo"    Feb-2010     20
4        A  "test"  March-2010     30
5        B   "foo"  March-2010     25

OLD(ER) VERSIONS: <0.20

You can use pd.melt to get most of the way there, and then sort:

>>> df
  location  name  Jan-2010  Feb-2010  March-2010
0        A  test        12        20          30
1        B   foo        18        20          25
>>> df2 = pd.melt(df, id_vars=["location", "name"], 
                  var_name="Date", value_name="Value")
>>> df2
  location  name        Date  Value
0        A  test    Jan-2010     12
1        B   foo    Jan-2010     18
2        A  test    Feb-2010     20
3        B   foo    Feb-2010     20
4        A  test  March-2010     30
5        B   foo  March-2010     25
>>> df2 = df2.sort(["location", "name"])
>>> df2
  location  name        Date  Value
0        A  test    Jan-2010     12
2        A  test    Feb-2010     20
4        A  test  March-2010     30
1        B   foo    Jan-2010     18
3        B   foo    Feb-2010     20
5        B   foo  March-2010     25

(Might want to throw in a .reset_index(drop=True), just to keep the output clean.)

Note: pd.DataFrame.sort has been deprecated in favour of pd.DataFrame.sort_values.

I know you asked how to do this, but the answer is you should not do this.

Instead, have a application.properties, application-default.properties application-dev.properties etc., and switch profiles via args to the JVM: e.g. -Dspring.profiles.active=dev

You can also override some things at test time using @TestPropertySource

Ideally everything should be in source control so that there are no surprises e.g. How do you know what properties are sitting there in your server location, and which ones are missing? What happens if developers introduce new things?

Spring Boot is already giving you enough ways to do this right.

https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-external-config.html

%matplotlib is a magic function in IPython. I'll quote the relevant documentation here for you to read for convenience:

IPython has a set of predefined ‘magic functions’ that you can call with a command line style syntax. There are two kinds of magics, line-oriented and cell-oriented. Line magics are prefixed with the % character and work much like OS command-line calls: they get as an argument the rest of the line, where arguments are passed without parentheses or quotes. Lines magics can return results and can be used in the right hand side of an assignment. Cell magics are prefixed with a double %%, and they are functions that get as an argument not only the rest of the line, but also the lines below it in a separate argument.

%matplotlib inline sets the backend of matplotlib to the 'inline' backend:

With this backend, the output of plotting commands is displayed inline within frontends like the Jupyter notebook, directly below the code cell that produced it. The resulting plots will then also be stored in the notebook document.

When using the 'inline' backend, your matplotlib graphs will be included in your notebook, next to the code. It may be worth also reading How to make IPython notebook matplotlib plot inline for reference on how to use it in your code.

If you want interactivity as well, you can use the nbagg backend with %matplotlib notebook (in IPython 3.x), as described here.

You can also consider using library maintained by me: ngx-store (npm i ngx-store)

It makes working with localStorage, sessionStorage and cookies incredibly easy. There are a few supported methods to manipulate the data:

1) Decorator:

export class SomeComponent {
  @LocalStorage() items: Array<string> = [];

  addItem(item: string) {
    this.items.push(item);
    console.log('current items:', this.items);
    // and that's all: parsing and saving is made by the lib in the background 
  }
}

Variables stored by decorators can be also shared across different classes - there is also @TempStorage() (with an alias of @SharedStorage())) decorator designed for it.

2) Simple service methods:

export class SomeComponent {
  constructor(localStorageService: LocalStorageService) {}

  public saveSettings(settings: SettingsInterface) {
    this.localStorageService.set('settings', settings);
  }

  public clearStorage() {
    this.localStorageService.utility
      .forEach((value, key) => console.log('clearing ', key));
    this.localStorageService.clear();
  }
}

3) Builder pattern:

interface ModuleSettings {
    viewType?: string;
    notificationsCount: number;
    displayName: string;
}

class ModuleService {
    constructor(public localStorageService: LocalStorageService) {}

    public get settings(): NgxResource<ModuleSettings> {
        return this.localStorageService
            .load(`userSettings`)
            .setPath(`modules`)
            .setDefaultValue({}) // we have to set {} as default value, because numeric `moduleId` would create an array 
            .appendPath(this.moduleId)
            .setDefaultValue({});
    }

    public saveModuleSettings(settings: ModuleSettings) {
        this.settings.save(settings);
    }

    public updateModuleSettings(settings: Partial<ModuleSettings>) {
        this.settings.update(settings);
    }
}

Another important thing is you can listen for (every) storage changes, e.g. (the code below uses RxJS v5 syntax):

this.localStorageService.observe()
  .filter(event => !event.isInternal)
  .subscribe((event) => {
    // events here are equal like would be in:
    // window.addEventListener('storage', (event) => {});
    // excluding sessionStorage events
    // and event.type will be set to 'localStorage' (instead of 'storage')
  });

WebStorageService.observe() returns a regular Observable, so you can zip, filter, bounce them etc.

I'm always open to hearing suggestions and questions helping me to improve this library and its documentation.

from http://code.google.com/p/fast-serialization/wiki/QuickStartHeapOff

What is Heap-Offloading ?

Usually all non-temporary objects you allocate are managed by java's garbage collector. Although the VM does a decent job doing garbage collection, at a certain point the VM has to do a so called 'Full GC'. A full GC involves scanning the complete allocated Heap, which means GC pauses/slowdowns are proportional to an applications heap size. So don't trust any person telling you 'Memory is Cheap'. In java memory consumtion hurts performance. Additionally you may get notable pauses using heap sizes > 1 Gb. This can be nasty if you have any near-real-time stuff going on, in a cluster or grid a java process might get unresponsive and get dropped from the cluster.

However todays server applications (frequently built on top of bloaty frameworks ;-) ) easily require heaps far beyond 4Gb.

One solution to these memory requirements, is to 'offload' parts of the objects to the non-java heap (directly allocated from the OS). Fortunately java.nio provides classes to directly allocate/read and write 'unmanaged' chunks of memory (even memory mapped files).

So one can allocate large amounts of 'unmanaged' memory and use this to save objects there. In order to save arbitrary objects into unmanaged memory, the most viable solution is the use of Serialization. This means the application serializes objects into the offheap memory, later on the object can be read using deserialization.

The heap size managed by the java VM can be kept small, so GC pauses are in the millis, everybody is happy, job done.

It is clear, that the performance of such an off heap buffer depends mostly on the performance of the serialization implementation. Good news: for some reason FST-serialization is pretty fast :-).

Sample usage scenarios:

• Session cache in a server application. Use a memory mapped file to store gigabytes of (inactive) user sessions. Once the user logs into your application, you can quickly access user-related data without having to deal with a database.
• Caching of computational results (queries, html pages, ..) (only applicable if computation is slower than deserializing the result object ofc).
• very simple and fast persistance using memory mapped files

Edit: For some scenarios one might choose more sophisticated Garbage Collection algorithms such as ConcurrentMarkAndSweep or G1 to support larger heaps (but this also has its limits beyond 16GB heaps). There is also a commercial JVM with improved 'pauseless' GC (Azul) available.

Procedure Example :

Create Procedure [dbo].[test]
@Name varchar(100),
@ID int Output   
As  
Begin   
SELECT @ID = UserID from tbl_UserMaster where  Name = @Name   
Return;
END     

How to call this procedure

Declare @ID int    
EXECUTE [dbo].[test] 'Abhishek',@ID OUTPUT   
PRINT @ID

I just spent the better half of my day coming up with a solution that actually worked for me and thought I would share what I did. The problem with the solutions above that I was having was that all of my paragraph elements would overlap with the footer I wanted at the bottom of the page. In order to get around this, I used the following CSS:

footer {
  font-size: 9px;
  color: #f00;
  text-align: center;
}

@page {
  size: A4;
  margin: 11mm 17mm 17mm 17mm;
}

@media print {
  footer {
    position: fixed;
    bottom: 0;
  }

  .content-block, p {
    page-break-inside: avoid;
  }

  html, body {
    width: 210mm;
    height: 297mm;
  }
}

The page-break-inside for p and content-block was crucial for me. Any time I have a p following an h*, I wrap them both in a div class = "content-block"> to ensure they stay together and don't break.

I'm hoping that someone finds this useful because it took me about 3 hours to figure out (I'm also new to CSS/HTML, so there's that...)

EDIT

Per a request in the comments, I am adding an example HTML document. You'll want to copy this into an HTML file, open it, and then choose to print the page. The print preview should show this working. It worked in Firefox and IE on my end, but Chrome made the font small enough to fit on one page, so it didn't work there.

For doing "normal" hash table lookups on basically any kind of data - this one by Paul Hsieh is the best I've ever used.

http://www.azillionmonkeys.com/qed/hash.html

If you care about cryptographically secure or anything else more advanced, then YMMV. If you just want a kick ass general purpose hash function for a hash table lookup, then this is what you're looking for.

Don't make it a int(), but make it a range() will solve this problem.

inp = range(input("Enter a number: "))

Storyboard Approach

Select CollectionView in your storyboard and go to size inspector and set min spacing for cells and lines as 5

Swift 5 Programmatically

lazy var collectionView: UICollectionView = {
        let layout = UICollectionViewFlowLayout()
        layout.scrollDirection = .horizontal

        //Provide Width and Height According to your need
        let width = UIScreen.main.bounds.width / 4
        let height = UIScreen.main.bounds.height / 10
        layout.itemSize = CGSize(width: width, height: height)

        //For Adjusting the cells spacing
        layout.minimumInteritemSpacing = 5
        layout.minimumLineSpacing = 5

        return UICollectionView(frame: self.view.frame, collectionViewLayout: layout)
    }()

Regarding CMake 3.13.3, platform Windows, and IDE Visual Studio 2017, I suggest this guide. In brief I suggest:
1. Download cmake > unzip it > execute it.
2. As example download GLFW > unzip it > create inside folder Build.
3. In cmake Browse "Source" > Browse "Build" > Configure and Generate.
4. In Visual Studio 2017 Build your Solution.
5. Get the binaries.

When you use the exec() function, it is as though you have a cmd terminal open and are typing commands straight to it.

Use single quotes like this $str = exec('start /B Path\to\batch.bat');
The /B means the bat will be executed in the background so the rest of the php will continue after running that line, as opposed to $str = exec('start /B /C command', $result); where command is executed and then result is stored for later use.

PS: It works for both Windows and Linux.
More details are here http://www.php.net/manual/en/function.exec.php :)

Great Jquery plugin to do exactly what your after

On Ubuntu, change the owner to the Apache group and grant the right permissions (no, it's not 777):

sudo chgrp www-data <path to db.sqlite3>
sudo chmod 664 <path to db.sqlite3>

Update

You can set the permissions for group and user as well.

sudo chown www-data:www-data <path to db.sqlite3>

You use the sql%rowcount variable.

You need to call it straight after the statement which you need to find the affected row count for.

For example:

set serveroutput ON; 
DECLARE 
    i NUMBER; 
BEGIN 
    UPDATE employees 
    SET    status = 'fired' 
    WHERE  name LIKE '%Bloggs'; 
    i := SQL%rowcount; 
    --note that assignment has to precede COMMIT
    COMMIT; 
    dbms_output.Put_line(i); 
END; 

Like the error says, row is a tuple, so you can't do row["pool_number"]. You need to use the index: row[0].

x = getattr(self, source) will work just perfectly if source names ANY attribute of self, including the other_data in your example.

Your answer for a non manual creation of an app.config is Visual Studio Project Properties/Settings tab.

When you add a setting and save, your app.config will be created automatically. At this point a bunch of code is generated in a {yourclasslibrary.Properties} namespace containing properties corresponding to your settings. The settings themselves will be placed in the app.config's applicationSettings settings.

    <sectionGroup name="applicationSettings" type="System.Configuration.ApplicationSettingsGroup, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" >
        <section name="ClassLibrary.Properties.Settings" type="System.Configuration.ClientSettingsSection, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
    </sectionGroup>
</configSections>
<applicationSettings>
    <ClassLibrary.Properties.Settings>
        <setting name="Setting1" serializeAs="String">
            <value>3</value>
        </setting>
    </BookOneGenerator.Properties.Settings>
</applicationSettings>

If you added an Application scoped setting called Setting1 = 3 then a property called Setting1 will be created. These properties are becoming at compilation part of the binary and they are decorated with a DefaultSettingValueAttribute which is set to the value you specified at development time.

     [ApplicationScopedSetting]
    [DebuggerNonUserCode]
    [DefaultSettingValue("3")]
    public string Setting1
    {
        get
        {
            return (string)this["Setting1"];
        }
    }

Thus as in your class library code you make use of these properties if a corresponding setting doesn't exist in the runtime config file, it will fallback to use the default value. That way the application won't crash for lacking a setting entry, which is very confusing first time when you don't know how these things work. Now, you're asking yourself how can specify our own new value in a deployed library and avoid the default setting value be used?

That will happen when we properly configure the executable's app.config. Two steps. 1. we make it aware that we will have a settings section for that class library and 2. with small modifications we paste the class library's config file in the executable config. (there's a method where you can keep the class library config file external and you just reference it from the executable's config.

So, you can have an app.config for a class library but it's useless if you don't integrate it properly with the parent application. See here what I wrote sometime ago: link

There is a default system button for "Refresh":

- (void)viewDidLoad {
    [super viewDidLoad];

    UIBarButtonItem *refreshButton = [[[UIBarButtonItem alloc] 
                            initWithBarButtonSystemItem:UIBarButtonSystemItemRefresh
                            target:self action:@selector(refreshClicked:)] autorelease];
    self.navigationItem.rightBarButtonItem = refreshButton;

}

- (IBAction)refreshClicked:(id)sender {

}

You are missing the dot on the selector, and you can use toggleClass method on jquery:

$(".result").hover(
  function () {
    $(this).toggleClass("result_hover")      
  }
);

The trick is to read the declaration backwards (right-to-left):

const int a = 1; // read as "a is an integer which is constant"
int const a = 1; // read as "a is a constant integer"

Both are the same thing. Therefore:

a = 2; // Can't do because a is constant

The reading backwards trick especially comes in handy when you're dealing with more complex declarations such as:

const char *s;      // read as "s is a pointer to a char that is constant"
char c;
char *const t = &c; // read as "t is a constant pointer to a char"

*s = 'A'; // Can't do because the char is constant
s++;      // Can do because the pointer isn't constant
*t = 'A'; // Can do because the char isn't constant
t++;      // Can't do because the pointer is constant

You may try

document.getElementById('name').style.borderColor='#e52213';
document.getElementById('name').style.border='solid';

You might want to look into my fork of pbzx here: https://github.com/NiklasRosenstein/pbzx

It allows you to stream pbzx files that are not wrapped in a XAR archive. I've experienced this with recent XCode Command-Line Tools Disk Images (eg. 10.12 XCode 8).

pbzx -n Payload | cpio -i

Thank you all for your answers.

Taking all of your answers as a guideline, I resolved the problem with the below code:

var valArr = [101,102];
i = 0, size = valArr.length;
for(i; i < size; i++){
  $("#data").multiselect("widget").find(":checkbox[value='"+valArr[i]+"']").attr("checked","checked");
  $("#data option[value='" + valArr[i] + "']").attr("selected", 1);
  $("#data").multiselect("refresh");
}

Thanks once again for all your support.

with unsrt the problem is the format. use \bibliographystyle{ieeetr} to get refences in order of citation in document.

Its fine to just do char **strings;, char **strings = NULL, or char **strings = {NULL}

but to initialize it you'd have to use malloc:

#include <stdlib.h>
#include <stdio.h>
#include <string.h>

int main(){
    // allocate space for 5 pointers to strings
    char **strings = (char**)malloc(5*sizeof(char*));
    int i = 0;
    //allocate space for each string
    // here allocate 50 bytes, which is more than enough for the strings
    for(i = 0; i < 5; i++){
        printf("%d\n", i);
        strings[i] = (char*)malloc(50*sizeof(char));
    }
    //assign them all something
    sprintf(strings[0], "bird goes tweet");
    sprintf(strings[1], "mouse goes squeak");
    sprintf(strings[2], "cow goes moo");
    sprintf(strings[3], "frog goes croak");
    sprintf(strings[4], "what does the fox say?");
    // Print it out
    for(i = 0; i < 5; i++){
        printf("Line #%d(length: %lu): %s\n", i, strlen(strings[i]),strings[i]);
    } 
    //Free each string
    for(i = 0; i < 5; i++){
        free(strings[i]);
    }
    //finally release the first string
    free(strings);
    return 0;
}

This works for me.

@{ var dic = new Dictionary<string, string>() { { "checked", "" } }; }

You're getting the error message

ValueError: setting an array element with a sequence.

because you're trying to set an array element with a sequence. I'm not trying to be cute, there -- the error message is trying to tell you exactly what the problem is. Don't think of it as a cryptic error, it's simply a phrase. What line is giving the problem?

kOUT[i]=func(TempLake[i],Z)

This line tries to set the ith element of kOUT to whatever func(TempLAke[i], Z) returns. Looking at the i=0 case:

In [39]: kOUT[0]
Out[39]: 0.0

In [40]: func(TempLake[0], Z)
Out[40]: array([ 0.,  0.,  0.,  0.])

You're trying to load a 4-element array into kOUT[0] which only has a float. Hence, you're trying to set an array element (the left hand side, kOUT[i]) with a sequence (the right hand side, func(TempLake[i], Z)).

Probably func isn't doing what you want, but I'm not sure what you really wanted it to do (and don't forget you can usually use vectorized operations like A*B rather than looping in numpy.) That should explain the problem, anyway.

Running .NET core (3.1.4) on IIS behind a Load balancer did not work with other suggested solutions.

Manually reading the X-Forwarded-For header does.

IPAddress ip;
var headers = Request.Headers.ToList();
if (headers.Exists((kvp) => kvp.Key == "X-Forwarded-For"))
{
    // when running behind a load balancer you can expect this header
    var header = headers.First((kvp) => kvp.Key == "X-Forwarded-For").Value.ToString();
    ip = IPAddress.Parse(header);
}
else
{
    // this will always have a value (running locally in development won't have the header)
    ip = Request.HttpContext.Connection.RemoteIpAddress;
}

Try this test:

any(substring in string for substring in substring_list)

It will return True if any of the substrings in substring_list is contained in string.

Note that there is a Python analogue of Marc Gravell's answer in the linked question:

from itertools import imap
any(imap(string.__contains__, substring_list)) 

In Python 3, you can use map directly instead:

any(map(string.__contains__, substring_list))

Probably the above version using a generator expression is more clear though.

One of the benefits is that Razor views can be rendered inside unit tests, this is something that was not easily possible with the previous ASP.Net renderer.

From ScottGu's announcement this is listed as one of the design goals:

Unit Testable: The new view engine implementation will support the ability to unit test views (without requiring a controller or web-server, and can be hosted in any unit test project – no special app-domain required).

imgDics = (ImageView) v.findViewById(R.id.img_player_tab2_dics);
    imgDics.setOnClickListener(onPlayer2Click);
    anim = new RotateAnimation(0f, 360f,

                            0.5f);
    anim.setInterpolator(new LinearInterpolator());
    anim.setRepeatCount(Animation.INFINITE);
    anim.setDuration(4000);

    // Start animating the image
    imgDics.startAnimation(anim);

All 3 of them represent the end of a line. But...

• \r (Carriage Return) → moves the cursor to the beginning of the line without advancing to the next line
• \n (Line Feed) → moves the cursor down to the next line without returning to the beginning of the line — In a *nix environment \n moves to the beginning of the line.
• \r\n (End Of Line) → a combination of \r and \n

You can search a directory using Find ? Find in files. This also includes all opened tabs.

The keyboard shortcut is Ctrl?+F on non-Mac (regular) keyboards, and ??+F on a Mac.

You'll be presented with three boxes: Find, Where and Replace. It's a regular Find/Find-replace search where Where specifies a file or directory to search. I for example often use a file name or . for searching the current directory. There are also a few special constructs that can be used within the Where field:

<project>,<current file>,<open files>,<open folders>,-*.doc,*.txt

Note that these are not placeholders, you type these verbatim. Most of them are self-explanatory (e.g. -*.doc excludes files with a .doc extension).

Pressing the ... to the right will present you with all available options.

After searching you'll be presented with a Find results page with all of your matching results. To jump to specific lines and files from it you simply double-click on a line.

You can install from nuget as the the below image:

Or, run the below command line on Package Manager Console:

Install-Package Microsoft.AspNet.WebApi

After doing a lot of things, I upgraded pip, setuptools and virtualenv.

1. python -m pip install -U pip
2. pip install -U setuptools
3. pip install -U virtualenv

I did steps 1, 2 in my virtual environment as well as globally. Next, I installed the package through pip and it worked.

Updated answer, from Peter in comments :

This is de "old terminology", use directally the WSDL2 "endepoint" definition (WSDL2 translated "port" to "endpoint").

Maybe you find an answer in this document : http://www.w3.org/TR/wsdl.html

A WSDL document defines services as collections of network endpoints, or ports. In WSDL, the abstract definition of endpoints and messages is separated from their concrete network deployment or data format bindings. This allows the reuse of abstract definitions: messages, which are abstract descriptions of the data being exchanged, and port types which are abstract collections of operations. The concrete protocol and data format specifications for a particular port type constitutes a reusable binding. A port is defined by associating a network address with a reusable binding, and a collection of ports define a service. Hence, a WSDL document uses the following elements in the definition of network services:

• Types– a container for data type definitions using some type system (such as XSD).
• Message– an abstract, typed definition of the data being communicated.
• Operation– an abstract description of an action supported by the service.
• Port Type–an abstract set of operations supported by one or more endpoints.
• Binding– a concrete protocol and data format specification for a particular port type.
• Port– a single endpoint defined as a combination of a binding and a network address.
• Service– a collection of related endpoints.

http://www.ehow.com/info_12212371_definition-service-endpoint.html

The endpoint is a connection point where HTML files or active server pages are exposed. Endpoints provide information needed to address a Web service endpoint. The endpoint provides a reference or specification that is used to define a group or family of message addressing properties and give end-to-end message characteristics, such as references for the source and destination of endpoints, and the identity of messages to allow for uniform addressing of "independent" messages. The endpoint can be a PC, PDA, or point-of-sale terminal.

Raw sql query is fastest way I suppose

public void DeleteCustomer(int id)
{
   using (var context = new Context())
   {
      const string query = "DELETE FROM [dbo].[Customers] WHERE [id]={0}";
      var rows = context.Database.ExecuteSqlCommand(query,id);
      // rows >= 1 - count of deleted rows,
      // rows = 0 - nothing to delete.
   }
}

This kind of thing doesn't just magically happen on its own; you changed something! In industry we use version control to make regular savepoints, so when something goes wrong we can trace back the specific changes we made that resulted in that problem.

Since you haven't done that here, we can only really guess. In Visual Studio, Intellisense (the technology that gives you auto-complete dropdowns and those squiggly red lines) works separately from the actual C++ compiler under the bonnet, and sometimes gets things a bit wrong.

In this case I'd ask why you're including both cstdlib and stdlib.h; you should only use one of them, and I recommend the former. They are basically the same header, a C header, but cstdlib puts them in the namespace std in order to "C++-ise" them. In theory, including both wouldn't conflict but, well, this is Microsoft we're talking about. Their C++ toolchain sometimes leaves something to be desired. Any time the Intellisense disagrees with the compiler has to be considered a bug, whichever way you look at it!

Anyway, your use of using namespace std (which I would recommend against, in future) means that std::system from cstdlib now conflicts with system from stdlib.h. I can't explain what's going on with std::cout and std::cin.

Try removing #include <stdlib.h> and see what happens.

If your program is building successfully then you don't need to worry too much about this, but I can imagine the false positives being annoying when you're working in your IDE.

You are trying to link objects compiled by different versions of the compiler. That's not supported in modern versions of VS, at least not if you are using the C++ standard library. Different versions of the standard library are binary incompatible and so you need all the inputs to the linker to be compiled with the same version. Make sure you re-compile all the objects that are to be linked.

The compiler error names the objects involved so the information the the question already has the answer you are looking for. Specifically it seems that the static library that you are linking needs to be re-compiled.

So the solution is to recompile Projectname1.lib with VS2012.
