This worked for me install php72-php-bcmath.x86_64 Then,

systemctl restart php72-php-fpm.service

Pinal Dave explains this well in his blog.

DECLARE @NewLineChar AS CHAR(2) = CHAR(13) + CHAR(10)
PRINT ('SELECT FirstLine AS FL ' + @NewLineChar + 'SELECT SecondLine AS SL')

This error is caused because the function createObjectURL is deprecated for Google Chrome

I changed this:

video.src=vendorUrl.createObjectURL(stream);
video.play();

to this:

video.srcObject=stream;
video.play();

This worked for me.

The output folder directory must have been configured to some other directory in IDE. Either you can change that or replace the filename with entire file path.

Hope this helps.

You can use Environment.Exit(0); and Application.Exit

Environment.Exit(0) is cleaner.

Just use android:inputType="textCapWords" in your EditText element.

For example:

<EditText
    android:id="@+id/txtName"
    android:layout_width="0dp"
    android:layout_height="40dp"
    android:layout_weight="0.7"
    android:inputType="textCapWords"
    android:textColorHint="#aaa"
    android:hint="Name Surname"
    android:textSize="12sp" />

Refer to the following link for reference: http://developer.android.com/reference/android/widget/TextView.html#attr_android%3ainputType

I find it easier to remember to just read it and then write it.

For example:

with open('file') as f:
    data = f.read()
with open('file', 'w') as f:
    f.write('hello')

You have to create either another page or generic handler with the code to generate your pdf. Then that event gets triggered and the person is redirected to that page.

One way to solve this problem, specialization of member functions is to put the specialization into another class, then inherit from that class. You may have to change the order of inheritence to get access to all of the other underlying data but this technique does work.

template< class T, bool condition> struct FooImpl;
template<class T> struct FooImpl<T, true> {
T foo() { return 10; }
};

template<class T> struct FoolImpl<T,false> {
T foo() { return 5; }
};

template< class T >
class Y : public FooImpl<T, boost::is_integer<T> > // whatever your test is goes here.
{
public:
    typedef FooImpl<T, boost::is_integer<T> > inherited;

    // you will need to use "inherited::" if you want to name any of the 
    // members of those inherited classes.
};

The disadvantage of this technique is that if you need to test a lot of different things for different member functions you'll have to make a class for each one, and chain it in the inheritence tree. This is true for accessing common data members.

Ex:

template<class T, bool condition> class Goo;
// repeat pattern above.

template<class T, bool condition>
class Foo<T, true> : public Goo<T, boost::test<T> > {
public:
    typedef Goo<T, boost::test<T> > inherited:
    // etc. etc.
};

Open httpd.conf of Apache server (backup first) Look for the the following : Listen

Change the line to

Listen *:80

Still in httpd.conf, look for the following (or similar):

<Directory />
    Options FollowSymLinks
    AllowOverride None
    Order deny,allow
    Allow from all
    Deny from all
</Directory>

Change this block to :

<Directory />
    Options FollowSymLinks
    AllowOverride None
    Order deny,allow
    Allow from all
    #Deny from all
</Directory>

Save httpd.conf and restart apache

Open port 80 of the server such that everyone can access your server.

Open Control Panel >> System and Security >> Windows Firewall then click on “Advance Setting” and then select “Inbound Rules” from the left panel and then click on “Add Rule…”. Select “PORT” as an option from the list and then in the next screen select “TCP” protocol and enter port number “80” under “Specific local port” then click on the ”Next” button and select “Allow the Connection” and then give the general name and description to this port and click Done.

Restart WAMP and access your machine in LAN or WAN.

Using javascript function it is easier to get all the attributes of an element in NamedArrayFormat.

$("#myTestDiv").click(function(){_x000D_
  var attrs = document.getElementById("myTestDiv").attributes;_x000D_
  $.each(attrs,function(i,elem){_x000D_
    $("#attrs").html(    $("#attrs").html()+"<br><b>"+elem.name+"</b>:<i>"+elem.value+"</i>");_x000D_
  });_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>_x000D_
<div id="myTestDiv" ekind="div" etype="text" name="stack">_x000D_
click This_x000D_
</div>_x000D_
<div id="attrs">Attributes are <div>

This issue occurs because of the Gradle version changes, since your application uses old version of gradle, you need to update to new version.

This changes needs to be done in build.gradle file, have look at this link http://www.feelzdroid.com/2015/11/android-plugin-too-old-update-recent-version.html. to know how to update the gradle and detailed steps are provided. there.

Thans

   xxx >& filename

Or do this to see everything on the screen and have it go to your file:

  xxx | & tee ./logfile

The identifing relaionship means the child entity is totally depend on the existance of the parent entity. Example account table person table and personaccount.The person account table is identified by the existance of account and person table only.

The non identifing relationship means the child table does not identified by the existance of the parent table example there is table as accounttype and account.accounttype table is not identified with the existance of account table.

If you're coming here wondering the opposite (as I was), this post may be for you.

I couldn't figure out why my notifications were clearing when I cleared the badge...I manually increment the badge and then want to clear it when the user enters the app. That's no reason to clear out the notification center, though; they may still want to see or act on those notifications.

Negative 1 does the trick, luckily:

[UIApplication sharedApplication].applicationIconBadgeNumber = -1;

Simply do the following:

I. Declare a global variable:

var markersArray = [];

II. Define a function:

function clearOverlays() {
  for (var i = 0; i < markersArray.length; i++ ) {
    markersArray[i].setMap(null);
  }
  markersArray.length = 0;
}

OR

google.maps.Map.prototype.clearOverlays = function() {
  for (var i = 0; i < markersArray.length; i++ ) {
    markersArray[i].setMap(null);
  }
  markersArray.length = 0;
}

III. Push markers in the 'markerArray' before calling the following:

markersArray.push(marker);
google.maps.event.addListener(marker,"click",function(){});

IV. Call the clearOverlays(); or map.clearOverlays(); function wherever required.

That's it!!

Download commons-net binary from here. Extract the files and reference the commons-net-x.x.jar file.

Okay you must try this guys it works for me:

1. Open SDK Manager and Install SDK build tools 22.0.1
2. Sync gradle That'all

A CustomValidator would also work here:

<asp:CustomValidator runat="server"
    ID="valDateRange" 
    ControlToValidate="txtDatecompleted"
    onservervalidate="valDateRange_ServerValidate" 
    ErrorMessage="enter valid date" />

Code-behind:

protected void valDateRange_ServerValidate(object source, ServerValidateEventArgs args)
{
    DateTime minDate = DateTime.Parse("1000/12/28");
    DateTime maxDate = DateTime.Parse("9999/12/28");
    DateTime dt;

    args.IsValid = (DateTime.TryParse(args.Value, out dt) 
                    && dt <= maxDate 
                    && dt >= minDate);
}

Nice looking solution would be to use a List instead of array in the first place.

List.remove(index)

If you have to use arrays, two calls to System.arraycopy will most likely be the fastest.

Foo[] result = new Foo[source.length - 1];
System.arraycopy(source, 0, result, 0, index);
if (source.length != index) {
    System.arraycopy(source, index + 1, result, index, source.length - index - 1);
}

(Arrays.asList is also a good candidate for working with arrays, but it doesn't seem to support remove.)

User johannes told you how to do add existing files to a Git repository in a general situation. Because you talk about Bitbucket, I suggest you do the following:

1. Create a new repository on Bitbucket (you can see a Create button on the top of your profile page) and you will go to this page:

   

2. Fill in the form, click next and then you automatically go to this page:

   

3. Choose to add existing files and you go to this page:

   

4. You use those commands and you upload the existing files to Bitbucket. After that, the files are online.

import java.util.Scanner;

class CalculateGCD 
{   
  public static int calGCD(int a, int b) 
  { 
   int c=0,d=0;  
   if(a>b){c=b;} 
   else{c=a;}  
   for(int i=c; i>0; i--) 
   { 
    if(((a%i)+(b%i))==0) 
    { 
     d=i; 
     break; 
    } 
   } 
   return d;  
  }  

  public static void main(String args[]) 
  { 
   Scanner sc=new Scanner(System.in); 
   System.out.println("Enter the nos whose GCD is to be calculated:"); 
   int a=sc.nextInt(); 
   int b=sc.nextInt(); 
   System.out.println(calGCD(a,b));  
  } 
 } 

The question didn't clarify what type of session store was being used. Both answers seem to be correct.

For cookie based sessions:

From http://expressjs.com/api.html#cookieSession

req.session = null // Deletes the cookie.

For Redis, etc based sessions:

req.session.destroy // Deletes the session in the database.

In my case, I have removed below line from MainApplication.java. (Which is previously mistakenly added by me.):-

import com.facebook.react.BuildConfig;

After that Clean Project and hit command

react-native run-android

^[A-Za-z][A-Za-z0-9]*(?:_[A-Za-z0-9]+)*$

Try using inner join in your Query

    Query query=session.createQuery("from Product as p INNER JOIN p.catalog as c 
    WHERE c.idCatalog= :id and p.productName like :XXX");
    query.setParameter("id", 7);
    query.setParameter("xxx", "%"+abc+"%");
    List list = query.list();

also in the hibernate config file have

<!--hibernate.cfg.xml -->
<property name="show_sql">true</property>

To display what is being queried on the console.

A method that I use is to load the table into R as a data.frame, then use dbWriteTable to push it to PostgreSQL. These two steps are shown below.

Load Excel data into R

R's data.frame objects are database-like, where named columns have explicit types, such as text or numbers. There are several ways to get a spreadsheet into R, such as XLConnect. However, a really simple method is to select the range of the Excel table (including the header), copy it (i.e. CTRL+C), then in R use this command to get it from the clipboard:

d <- read.table("clipboard", header=TRUE, sep="\t", quote="\"", na.strings="", as.is=TRUE)

If you have RStudio, you can easily view the d object to make sure it is as expected.

Push it to PostgreSQL

Ensure you have RPostgreSQL installed from CRAN, then make a connection and send the data.frame to the database:

library(RPostgreSQL)
conn <- dbConnect(PostgreSQL(), dbname="mydb")

dbWriteTable(conn, "some_table_name", d)

Now some_table_name should appear in the database.

Some common clean-up steps can be done from pgAdmin or psql:

ALTER TABLE some_table_name RENAME "row.names" TO id;
ALTER TABLE some_table_name ALTER COLUMN id TYPE integer USING id::integer;
ALTER TABLE some_table_name ADD PRIMARY KEY (id);

the key things to know for operations on NumPy arrays versus operations on NumPy matrices are:

• NumPy matrix is a subclass of NumPy array

• NumPy array operations are element-wise (once broadcasting is accounted for)

• NumPy matrix operations follow the ordinary rules of linear algebra

some code snippets to illustrate:

>>> from numpy import linalg as LA
>>> import numpy as NP

>>> a1 = NP.matrix("4 3 5; 6 7 8; 1 3 13; 7 21 9")
>>> a1
matrix([[ 4,  3,  5],
        [ 6,  7,  8],
        [ 1,  3, 13],
        [ 7, 21,  9]])

>>> a2 = NP.matrix("7 8 15; 5 3 11; 7 4 9; 6 15 4")
>>> a2
matrix([[ 7,  8, 15],
        [ 5,  3, 11],
        [ 7,  4,  9],
        [ 6, 15,  4]])

>>> a1.shape
(4, 3)

>>> a2.shape
(4, 3)

>>> a2t = a2.T
>>> a2t.shape
(3, 4)

>>> a1 * a2t         # same as NP.dot(a1, a2t) 
matrix([[127,  84,  85,  89],
        [218, 139, 142, 173],
        [226, 157, 136, 103],
        [352, 197, 214, 393]])

but this operations fails if these two NumPy matrices are converted to arrays:

>>> a1 = NP.array(a1)
>>> a2t = NP.array(a2t)

>>> a1 * a2t
Traceback (most recent call last):
   File "<pyshell#277>", line 1, in <module>
   a1 * a2t
   ValueError: operands could not be broadcast together with shapes (4,3) (3,4) 

though using the NP.dot syntax works with arrays; this operations works like matrix multiplication:

>> NP.dot(a1, a2t)
array([[127,  84,  85,  89],
       [218, 139, 142, 173],
       [226, 157, 136, 103],
       [352, 197, 214, 393]])

so do you ever need a NumPy matrix? ie, will a NumPy array suffice for linear algebra computation (provided you know the correct syntax, ie, NP.dot)?

the rule seems to be that if the arguments (arrays) have shapes (m x n) compatible with the a given linear algebra operation, then you are ok, otherwise, NumPy throws.

the only exception i have come across (there are likely others) is calculating matrix inverse.

below are snippets in which i have called a pure linear algebra operation (in fact, from Numpy's Linear Algebra module) and passed in a NumPy array

determinant of an array:

>>> m = NP.random.randint(0, 10, 16).reshape(4, 4)
>>> m
array([[6, 2, 5, 2],
       [8, 5, 1, 6],
       [5, 9, 7, 5],
       [0, 5, 6, 7]])

>>> type(m)
<type 'numpy.ndarray'>

>>> md = LA.det(m)
>>> md

matrix condition:

>>> a1 = NP.random.randint(1, 10, 12).reshape(4, 3)

This happened to me because I had the 'copyright' symbol in one of my strings! Once it was removed, problem solved.

A good rule of thumb, make sure that characters not appearing on your keyboard are removed if you are seeing this error.

You can simply ping an online website like google:

    String command = "ping -c 1 google.com";
    return Runtime.getRuntime().exec(command).waitFor() == 0;
}

If you are using the latest versions of macOS, then you cannot use ~/.bash_profile to export your environment variable since the bash shell is deprecated in the latest version of macOS.

• Run /usr/libexec/java_home in your terminal and you will get things like /Library/Java/JavaVirtualMachines/jdk1.8.0_261.jdk/Contents/Home
• Add export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_261.jdk/Contents/Home to .zshrc

The first case will fail when JS is off. It's also a little bit slower since JS must be parsed first (DOM must be loaded). However JS is safer since the destination doesn't know the referer and your redirect might be tracked (referers aren't reliable in general yet this is something).

You can also use meta refresh tag. It also requires DOM to be loaded.

You can use:

=IF(ISBLANK(A1),1,0)

but you should be careful what you mean by empty cell. I've been caught out by this before. If you want to know if a cell is truly blank, isblank, as above, will work. Unfortunately, you sometimes also need to know if it just contains no useful data.

The expression:

=IF(ISBLANK(A1),TRUE,(TRIM(A1)=""))

will return true for cells that are either truly blank, or contain nothing but white space.

Here's the results when column A contains varying amounts of spaces, column B contains the length (so you know how many spaces) and column C contains the result of the above expression:

To return 1 if the cell is blank or white space and 0 otherwise:

=IF(ISBLANK(A1),1,if(TRIM(A1)="",1,0))

will do the trick.

This trick comes in handy when the cell that you're checking is actually the result of an Excel function. Many Excel functions (such as trim) will return an empty string rather than a blank cell.

You can see this in action with a new sheet. Leave cell A1 as-is and set A2 to =trim(a1).

Then set B1 to =isblank(a1) and B2 to isblank(a2). You'll see that the former is true while the latter is false.

import csv

with open('filepath/filename.csv', "rt", encoding='ascii') as infile:
    read = csv.reader(infile)
    for row in read :
        print (row)

This will solve your problem. Don't forget to give the encoding.

To check if a string variable contains a valid email address, the easiest way is to test it against a regular expression. There is a good discussion of various regex's and their trade-offs at regular-expressions.info.

Here is a relatively simple one that leans on the side of allowing some invalid addresses through: ^[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,6}$

How you can use regular expressions depends on the version of iOS you are using.

iOS 4.x and Later

You can use NSRegularExpression, which allows you to compile and test against a regular expression directly.

iOS 3.x

Does not include the NSRegularExpression class, but does include NSPredicate, which can match against regular expressions.

NSString *emailRegex = ...;
NSPredicate *emailTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", emailRegex];
BOOL isValid = [emailTest evaluateWithObject:checkString];

Read a full article about this approach at cocoawithlove.com.

iOS 2.x

Does not include any regular expression matching in the Cocoa libraries. However, you can easily include RegexKit Lite in your project, which gives you access to the C-level regex APIs included on iOS 2.0.

Define class method:

class Foo(object):
    bar = 1
    @classmethod
    def bah(cls):    
        print cls.bar

Now if bah() has to be instance method (i.e. have access to self), you can still directly access the class variable.

class Foo(object):
    bar = 1
    def bah(self):    
        print self.bar

//for excluding zero
public class SmallestInt {

    public static void main(String[] args) {

        Scanner input= new Scanner(System.in);

        System.out.println("enter number");
        int val=input.nextInt();
        int min=val;

        //String notNull;

        while(input.hasNextInt()==true)
        {
            val=input.nextInt();
            if(val<min)
                min=val;
        }
        System.out.println("min is: "+min);
    }
}

The answer given by NINCOMPOOP can be made simpler using Lambda Expressions:

Collections.sort(recipes, (Recipe r1, Recipe r2) ->
r1.getID().compareTo(r2.getID()));

Also introduced after Java 8 is the comparator construction methods in the Comparator interface. Using these, one can further reduce this to ¹:

recipes.sort(comparingInt(Recipe::getId));

You can do it with a pivot query, like this:

select * from (
   select LOAN_NUMBER, DOCUMENT_TYPE, DOCUMENT_ID
   from my_table t
)
pivot 
(
   MIN(DOCUMENT_ID)
   for DOCUMENT_TYPE in ('Voters ID','Pan card','Drivers licence')
)

Try Logic Friday 1 It includes tools from the Univerity of California (Espresso and misII) and makes them usable with a GUI. You can enter boolean equations and truth tables as desired. It also features a graphical gate diagram input and output.

The minimization can be carried out two-level or multi-level. The two-level form yields a minimized sum of products. The multi-level form creates a circuit composed out of logical gates. The types of gates can be restricted by the user.

Your expression simplifies to C.

See below link : http://www.asciitable.com/

public static char randomSeriesForThreeCharacter() {
    Random r = new Random();
    char random_3_Char = (char) (48 + r.nextInt(47));
    return random_3_Char;
}

Now you can generate a character at one time of calling.

using ylim() might be the best approach for your purpose:

xValues = list(range(10))
quads = [x** 2 for x in xValues]
plt.ylim(max(quads), 0)
plt.plot(xValues, quads)

will result:

Try this I learned this from @nmaier when I was mucking around with converting to ico: Well i dont really understand what array buffer is but it does what we need:

function previewFile(file) {

  var reader  = new FileReader();

  reader.onloadend = function () {
    console.log(reader.result); //this is an ArrayBuffer
  }
  reader.readAsArrayBuffer(file);
}

notice how i just changed your readAsDataURL to readAsArrayBuffer.

Here is the example @nmaier gave me: https://stackoverflow.com/a/24253997/1828637

it has a fiddle

if you want to take this and make a file out of it i would think you would use file-output-stream in the onloadend

You can get the Class reference of any class during run time through the Java Reflection Concept.

Check the Below Code. Explanation is given below

Here is one example that uses returned Class to create an instance of AClass:

package com.xyzws;
class AClass {
    public AClass() {
        System.out.println("AClass's Constructor"); 
    }  
    static {   
        System.out.println("static block in AClass");  
    }
}
public class Program {   
    public static void main(String[] args) {
        try {       
            System.out.println("The first time calls forName:");   
            Class c = Class.forName("com.xyzws.AClass");      
            AClass a = (AClass)c.newInstance();    
            System.out.println("The second time calls forName:");  
            Class c1 = Class.forName("com.xyzws.AClass"); 
        } catch (ClassNotFoundException e) { 
            // ...
        } catch (InstantiationException e) {  
            // ...
        } catch (IllegalAccessException e) { 
            // ...
        }     
    }
}

The printed output is

    The first time calls forName:
    static block in AClass
    AClass's Constructor
    The second time calls forName:

The class has already been loaded so there is no second "static block in AClass"

The Explanation is below

Class.ForName is called to get a Class Object

By Using the Class Object we are creating the new instance of the Class.

dataGridView1.SelectedRows.Select(r => r.Index);

SQLite out-of-the-box is not really feature-full regarding concurrency. You will get into trouble if you have hundreds of web requests hitting the same SQLite database.

You should definitely go with MySQL or PostgreSQL.

If it is for a single-person project, SQLite will be easier to setup though.

Also in the many IDEs now, ex: VSC, you can install an extension for AWS and simply click upload from there, no effort of typing all those commands + region.

Here's an example:

Uri myUri = Uri.parse("http://www.google.com");

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.

 <configSections>
    <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

I had the same issue with firefox, when I searched for a solution I didn't find anything, but then I tried to load the script from a cdn, it worked properly, so I think you should try loading it from a cdn link, I mean if you are trying to load a script that you havn't created. because in my case, when tried to load a script that is mine, it worked and imported successfully, for now I don't know why, but I think there is something in the scripts from network, so just try cdn, you won't lose anything.

I wish it help you.

You may want to visit page Scroll Web elements and Web page- Selenium WebDriver using Javascript:

public static void main(String[] args) throws Exception {

    // TODO Auto-generated method stub
    FirefoxDriver ff = new FirefoxDriver();
    ff.get("http://toolsqa.com");
    Thread.sleep(5000);
    ff.executeScript("document.getElementById('text-8').scrollIntoView(true);");
}

It would be nice to be able to specify a port other than 3000, either as a command line parameter or an environment variable.

Right now, the process is pretty involved:

1. Run npm run eject
2. Wait for that to finish
3. Edit scripts/start.js and find/replace 3000 with whatever port you want to use
4. Edit config/webpack.config.dev.js and do the same
5. npm start

What system are you on? It looks like you have a system with X11, but the DISPLAY environment variable was not properly set. Try executing the following command and then rerunning your program:

export DISPLAY=localhost:0

This works for me.

var httpWebRequest = (HttpWebRequest)WebRequest.Create("http://url");
httpWebRequest.ContentType = "application/json";
httpWebRequest.Method = "POST";
using (var streamWriter = new 

StreamWriter(httpWebRequest.GetRequestStream()))
{
    string json = new JavaScriptSerializer().Serialize(new
                {
                    Username = "myusername",
                    Password = "password"
                });

    streamWriter.Write(json);
}
var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
{
    var result = streamReader.ReadToEnd();
}

Offset Means "the amount or distance by which something is out of line". Margin or Borders are something which makes the actual height or width of an HTML element "out of line". It will help you to remember that :

• offsetHeight is a measurement in pixels of the element's CSS height, including border, padding and the element's horizontal scrollbar.

On the other hand, clientHeight is something which is you can say kind of the opposite of OffsetHeight. It doesn't include the border or margins. It does include the padding because it is something that resides inside of the HTML container, so it doesn't count as extra measurements like margin or border. So :

• clientHeight property returns the viewable height of an element in pixels, including padding, but not the border, scrollbar or margin.

ScrollHeight is all the scrollable area, so your scroll will never run over your margin or border, so that's why scrollHeight doesn't include margin or borders but yeah padding does. So:

• scrollHeight value is equal to the minimum height the element would require in order to fit all the content in the viewport without using a vertical scrollbar. The height is measured in the same way as clientHeight: it includes the element's padding, but not its border, margin or horizontal scrollbar.

Put quite simply:

SELECT 'This is Ashok''s Pen.';

So inside the string, replace each single quote with two of them.

Or:

SELECT 'This is Ashok\'s Pen.'

Escape it =)

The simplest way to create a manifest is:

Project Properties -> Security -> Click "enable ClickOnce security settings" 
(it will generate default manifest in your project Properties) -> then Click 
it again in order to uncheck that Checkbox -> open your app.maifest and edit 
it as you wish.

And yet another variation

a = ['12','34','35','231']
a.to_s.gsub(/\"/, '\'').gsub(/[\[\]]/, '')

Unlike in C# where you have the Array.IndexOf method, and JavaScript where you have the indexOf method, Java's API (the Array and Arrays classes in particular) have no such method.

This method indexOf (together with its complement lastIndexOf) is defined in the java.util.List interface. Note that indexOf and lastIndexOf are not overloaded and only take an Object as a parameter.

If your array is sorted, you are in luck because the Arrays class defines a series of overloads of the binarySearch method that will find the index of the element you are looking for with best possible performance (O(log n) instead of O(n), the latter being what you can expect from a sequential search done by indexOf). There are four considerations:

1. The array must be sorted either in natural order or in the order of a Comparator that you provide as an argument, or at the very least all elements that are "less than" the key must come before that element in the array and all elements that are "greater than" the key must come after that element in the array;

2. The test you normally do with indexOf to determine if a key is in the array (verify if the return value is not -1) does not hold with binarySearch. You need to verify that the return value is not less than zero since the value returned will indicate the key is not present but the index at which it would be expected if it did exist;

3. If your array contains multiple elements that are equal to the key, what you get from binarySearch is undefined; this is different from indexOf that will return the first occurrence and lastIndexOf that will return the last occurrence.

4. An array of booleans might appear to be sorted if it first contains all falses and then all trues, but this doesn't count. There is no override of the binarySearch method that accepts an array of booleans and you'll have to do something clever there if you want O(log n) performance when detecting where the first true appears in an array, for instance using an array of Booleans and the constants Boolean.FALSE and Boolean.TRUE.

If your array is not sorted and not primitive type, you can use List's indexOf and lastIndexOf methods by invoking the asList method of java.util.Arrays. This method will return an AbstractList interface wrapper around your array. It involves minimal overhead since it does not create a copy of the array. As mentioned, this method is not overloaded so this will only work on arrays of reference types.

If your array is not sorted and the type of the array is primitive, you are out of luck with the Java API. Write your own for loop, or your own static utility method, which will certainly have performance advantages over the asList approach that involves some overhead of an object instantiation. In case you're concerned that writing a brute force for loop that iterates over all of the elements of the array is not an elegant solution, accept that that is exactly what the Java API is doing when you call indexOf. You can make something like this:

public static int indexOfIntArray(int[] array, int key) {
    int returnvalue = -1;
    for (int i = 0; i < array.length; ++i) {
        if (key == array[i]) {
            returnvalue = i;
            break;
        }
    }
    return returnvalue;
}

If you want to avoid writing your own method here, consider using one from a development framework like Guava. There you can find an implementation of indexOf and lastIndexOf.

You can try the code below:

# Load the packages required to read XML files.
library("XML")
library("methods")

# Convert the input xml file to a data frame.
xmldataframe <- xmlToDataFrame("input.xml")
print(xmldataframe)

As previously mentioned - in case of a project, Makefile or otherwise, this is a project configuration issue, where you'll likely need to specify other flags too.

But what about one-off programs, where you would normally just write g++ file.cpp && ./a.out?

Well, I would much like to have some #pragma to turn in on at source level, or maybe a default extension - say .cxx or .C11 or whatever, trigger it by default. But as of today, there is no such feature.

But, as you probably are working in a manual environment (i.e. shell), you can just have an alias in you .bashrc (or whatever):

alias g++11="g++ -std=c++0x"

or, for newer G++ (and when you want to feel "real C++11")

alias g++11="g++ -std=c++11"

You can even alias to g++ itself, if you hate C++03 that much ;)

BundleConfig is nothing more than bundle configuration moved to separate file. It used to be part of app startup code (filters, bundles, routes used to be configured in one class)

To add this file, first you need to add the Microsoft.AspNet.Web.Optimization nuget package to your web project:

Install-Package Microsoft.AspNet.Web.Optimization

Then under the App_Start folder create a new cs file called BundleConfig.cs. Here is what I have in my mine (ASP.NET MVC 5, but it should work with MVC 4):

using System.Web;
using System.Web.Optimization;

namespace CodeRepository.Web
{
    public class BundleConfig
    {
        // For more information on bundling, visit http://go.microsoft.com/fwlink/?LinkId=301862
        public static void RegisterBundles(BundleCollection bundles)
        {
            bundles.Add(new ScriptBundle("~/bundles/jquery").Include(
                        "~/Scripts/jquery-{version}.js"));

            bundles.Add(new ScriptBundle("~/bundles/jqueryval").Include(
                        "~/Scripts/jquery.validate*"));

            // Use the development version of Modernizr to develop with and learn from. Then, when you're
            // ready for production, use the build tool at http://modernizr.com to pick only the tests you need.
            bundles.Add(new ScriptBundle("~/bundles/modernizr").Include(
                        "~/Scripts/modernizr-*"));

            bundles.Add(new ScriptBundle("~/bundles/bootstrap").Include(
                      "~/Scripts/bootstrap.js",
                      "~/Scripts/respond.js"));

            bundles.Add(new StyleBundle("~/Content/css").Include(
                      "~/Content/bootstrap.css",
                      "~/Content/site.css"));
        }
    }
}

Then modify your Global.asax and add a call to RegisterBundles() in Application_Start():

using System.Web.Optimization;

protected void Application_Start()
{
    AreaRegistration.RegisterAllAreas();
    RouteConfig.RegisterRoutes(RouteTable.Routes);
    BundleConfig.RegisterBundles(BundleTable.Bundles);
}

If you are encrypting a text file, then the following test/sample may be useful. It does the following:

1. Create a byte stream,
2. wraps that with AES encryption,
3. wrap it next with text processing

You can simply use:

mvn --settings YourOwnSettings.xml clean install

or

mvn -s YourOwnSettings.xml clean install

My app was transitioned to Xcode 5 seamlessly because it can still build with the original iOS Deployment Target that you set in the project (5.1 in my case). If the new SDK doesn't cause some insurmountable problem, then why not build using it? Surely there are many improvements under the hood.

For example, I will much prefer to use Xcode 5 instead of Xcode 4.6.3. Why? I'll get a lot more battery life because the UI scrolling of text/code areas in Xcode 5 no longer chews up an entire CPU thread.

Per Arvand:
Eclipse: Simply type android.R.layout.simple_list_item_1 somewhere in code, hold Ctrl, hover over simple_list_item_1, and from the dropdown that appears select Open declaration in layout/simple_list_item_1.xml. It'll direct you to the contents of the XML.

From there, if you then hover over the resulting simple_list_item_1.xml tab in the Editor, you'll see the file is located at C:\Data\applications\Android\android-sdk\platforms\android-19\data\res\layout\simple_list_item_1.xml (or equivalent location for your installation).

JUnit 4.4 is not supported by the JMockit/JUnit integration. Only versions 4.5 or newer are supported that.

ByteArrayInputStream also does the trick:

InputStream is = new ByteArrayInputStream( myString.getBytes( charset ) );

Then convert to reader:

InputStreamReader reader = new InputStreamReader(is);

You can Enable DBMS_OUTPUT and set the buffer size. The buffer size can be between 1 and 1,000,000.

dbms_output.enable(buffer_size IN INTEGER DEFAULT 20000);
exec dbms_output.enable(1000000);

Check this

EDIT

As per the comment posted by Frank and Mat, you can also enable it with Null

exec dbms_output.enable(NULL);

buffer_size : Upper limit, in bytes, the amount of buffered information. Setting buffer_size to NULL specifies that there should be no limit. The maximum size is 1,000,000, and the minimum is 2,000 when the user specifies buffer_size (NOT NULL).

Pseudo code from Wikipedia translated into the most compact Java

(year % 400 == 0) || ((year % 4 == 0) && (year % 100 != 0))

I strongly recommend using a combination of GitLens & GitGraph.

And the below picture is for the the amazing vivid GitGraph

When making OUTER JOINs (ANSI-89 or ANSI-92), filtration location matters because criteria specified in the ON clause is applied before the JOIN is made. Criteria against an OUTER JOINed table provided in the WHERE clause is applied after the JOIN is made. This can produce very different result sets. In comparison, it doesn't matter for INNER JOINs if the criteria is provided in the ON or WHERE clauses -- the result will be the same.

  SELECT  s.*, 
          cs.`value`
     FROM SETTINGS s
LEFT JOIN CHARACTER_SETTINGS cs ON cs.setting_id = s.id
                               AND cs.character_id = 1

To avoid problems with layout_* params not being properly used, you need to make sure that when you inflate your custom layout that you specify a correct ViewGroup as a parent.

Many examples pass null here, but instead you can pass the existing Toast ViewGroup as your parent.

val toast = Toast.makeText(this, "", Toast.LENGTH_LONG)
val layout = LayoutInflater.from(this).inflate(R.layout.view_custom_toast, toast.view.parent as? ViewGroup?)
toast.view = layout
toast.show()

Here we replace the existing Toast view with our custom view. Once you have a reference to your layout "layout" you can then update any images/text views that it may contain.

This solution also prevents any "View not attached to window manager" crashes from using null as a parent.

Also, avoid using ConstraintLayout as your custom layout root, this seems to not work when used inside a Toast.

I would use a decimal with the proper precision for your data.

var shadows = UIView()
shadows.frame = view.frame
shadows.clipsToBounds = false
view.addSubview(shadows)


let shadowPath0 = UIBezierPath(roundedRect: shadows.bounds, cornerRadius: 10)
let layer0 = CALayer()
layer0.shadowPath = shadowPath0.cgPath
layer0.shadowColor = UIColor(red: 0, green: 0, blue: 0, alpha: 0.23).cgColor
layer0.shadowOpacity = 1
layer0.shadowRadius = 6
layer0.shadowOffset = CGSize(width: 0, height: 3)
layer0.bounds = shadows.bounds
layer0.position = shadows.center

shadows.layer.addSublayer(layer0)

var anchor = angular.element('<a/>');
anchor.css({display: 'none'}); // Make sure it's not visible
angular.element(document.body).append(anchor); // Attach to document

anchor.attr({
    href: 'data:attachment/csv;charset=utf-8,' + encodeURI(data),
    target: '_blank',
    download: 'filename.csv'
})[0].click();

anchor.remove(); // Clean it up afterwards

Maybe a little late to reply. I happen to run into the same problem today. I find that on Windows you can change the console encoder to utf-8 or other encoder that can represent your data. Then you can print it to sys.stdout.

First, run following code in the console:

chcp 65001
set PYTHONIOENCODING=utf-8

Then, start python do anything you want.

Related answer, but if you want to run clean up a user inputting values into a form, here's what you can do:

const numFormatter = new Intl.NumberFormat('en-US', {
  style: "decimal",
  maximumFractionDigits: 2
})

// Good Inputs
parseFloat(numFormatter.format('1234').replace(/,/g,"")) // 1234
parseFloat(numFormatter.format('123').replace(/,/g,"")) // 123

// 3rd decimal place rounds to nearest
parseFloat(numFormatter.format('1234.233').replace(/,/g,"")); // 1234.23
parseFloat(numFormatter.format('1234.239').replace(/,/g,"")); // 1234.24

// Bad Inputs
parseFloat(numFormatter.format('1234.233a').replace(/,/g,"")); // NaN
parseFloat(numFormatter.format('$1234.23').replace(/,/g,"")); // NaN

// Edge Cases
parseFloat(numFormatter.format(true).replace(/,/g,"")) // 1
parseFloat(numFormatter.format(false).replace(/,/g,"")) // 0
parseFloat(numFormatter.format(NaN).replace(/,/g,"")) // NaN

Use the international date local via format. This cleans up any bad inputs, if there is one it returns a string of NaN you can check for. There's no way currently of removing commas as part of the locale (as of 10/12/19), so you can use a regex command to remove commas using replace.

ParseFloat converts the this type definition from string to number

If you use React, this is what your calculate function could look like:

updateCalculationInput = (e) => {
    let value;
    value = numFormatter.format(e.target.value); // 123,456.78 - 3rd decimal rounds to nearest number as expected
    if(value === 'NaN') return; // locale returns string of NaN if fail
    value = value.replace(/,/g, ""); // remove commas
    value = parseFloat(value); // now parse to float should always be clean input

    // Do the actual math and setState calls here
}

If you have mistakenly named the local name as "origin", you may remove it with the following:

git remote rm origin

If you want a list of lists:

>>> [list(t) for t in zip(*l)]
[[1, 3, 8], [2, 4, 9]]

If a list of tuples is OK:

>>> zip(*l)
[(1, 3, 8), (2, 4, 9)]

You can look at Open Source QR Code Library or messagingtoolkit-qrcode. I have not used either of them so I can not speak of their ease to use.

It is much more accurate to use IndexOf:

If dt.Columns.IndexOf("ColumnName") = -1 Then
    'Column not exist
End If

If the Contains is used it would not differentiate between ColumName and ColumnName2.

Assuming SQL Server (based on your previous questions):

ALTER TABLE Merchant_Pending_Functions ALTER COLUMN NumberOfLocations INT NULL

Replace INT with your actual datatype.

Though this was raised long ago, still a most wanted validation. I found an interesting blog with few function.

/* Please use these function to check the reuslt only. do not check for otherewise. other than utiljs_isInvalidDate

Ex:-

utiljs_isFutureDate() retuns only true for future dates. false does not mean it is not future date. it may be an invalid date.

practice :

call utiljs_isInvalidDate first and then use the returned date for utiljs_isFutureDate()

var d = {};

if(!utiljs_isInvalidDate('32/02/2012', d))

if(utiljs_isFutureDate(d))

To have in Visual Studio Code what you can do in Sublime Text ( CTRL+K CTRL+U and CTRL+K CTRL+L ) you could do this:

• Open "Keyboard Shortcuts" with click on "File -> Preferences -> Keyboard Shortcuts"
• Click on "keybindings.json" link which appears under "Search keybindings" field

• Between the [] brackets add:

  {
      "key": "ctrl+k ctrl+u",
      "command": "editor.action.transformToUppercase",
      "when": "editorTextFocus"
  },
  {
      "key": "ctrl+k ctrl+l",
      "command": "editor.action.transformToLowercase",
      "when": "editorTextFocus"
  }
  

• Save and close "keybindings.json"

Add the following CSS;

.modal .modal-dialog .modal-content{  background-color: #d4c484; }

<div class="modal fade">
<div class="modal-dialog" role="document">
<div class="modal-content">
...
...

This worked for me

$(".chzn-select").chosen({

     disable_search_threshold: 10

}).change(function(event){

     if(event.target == this){
        alert($(this).val());
     }

});

If you are using Java 6 or higher you can use wildcards of this form:

java -classpath ".;c:\mylibs\*;c:\extlibs\*" MyApp

If you would like to add all subdirectories: lib\a\, lib\b\, lib\c\, there is no mechanism for this in except:

java -classpath ".;c:\lib\a\*;c:\lib\b\*;c:\lib\c\*" MyApp

There is nothing like lib\*\* or lib\** wildcard for the kind of job you want to be done.

I guess to some degree it's a DBA vs. developer issue.

As a dev mostly, I'd say don't use it unless you absolutely positively have to - because using it can break your ADO.NET code (as documented by Microsoft).

And I guess as a DBA, you'd be more on the other side - use it whenever possible unless you really must prevent it's usage.

Also, if your devs ever use the "RecordsAffected" being returned by ADO.NET's ExecuteNonQuery method call, you're in trouble if everyone uses SET NOCOUNT ON since in this case, ExecuteNonQuery will always return 0.

Also see Peter Bromberg's blog post and check out his position.

So it really boils down to who gets to set the standards :-)

As per doc http://dev.mysql.com/doc/refman/5.0/en/server-status-variables.html#statvar_Connections

Connections

The number of connection attempts (successful or not) to the MySQL server.

There is a difference, but subtle. Look at it this way: struct Foo introduces a new type. The second one creates an alias called Foo (and not a new type) for an unnamed struct type.

7.1.3 The typedef specifier

1 [...]

A name declared with the typedef specifier becomes a typedef-name. Within the scope of its declaration, a typedef-name is syntactically equivalent to a keyword and names the type associated with the identifier in the way described in Clause 8. A typedef-name is thus a synonym for another type. A typedef-name does not introduce a new type the way a class declaration (9.1) or enum declaration does.

8 If the typedef declaration defines an unnamed class (or enum), the first typedef-name declared by the declaration to be that class type (or enum type) is used to denote the class type (or enum type) for linkage purposes only (3.5). [ Example:

typedef struct { } *ps, S; // S is the class name for linkage purposes

So, a typedef always is used as an placeholder/synonym for another type.

Honestly, the best way to limit files is on the server side. People can spoof file type on the client so taking in the full file name at server transfer time, parsing out the file type, and then returning a message is usually the best bet.

Check if the file path is correct and the file exists - in my case that was the issue - as I fixed it, the error disappeared

This answer uses the DataFrame.filter method to do this without list comprehension:

import pandas as pd

data = {'spike-2': [1,2,3], 'hey spke': [4,5,6]}
df = pd.DataFrame(data)

print(df.filter(like='spike').columns)

Will output just 'spike-2'. You can also use regex, as some people suggested in comments above:

print(df.filter(regex='spike|spke').columns)

Will output both columns: ['spike-2', 'hey spke']

Sounds like you need to create your own pair class (see discussion here). Then make a List of that pair class you created

You can also try nodemon

To Install Nodemon

npm install -g nodemon

To use Nodemon

Normally we start node program like:

node server.js

But here you have to do like:

nodemon server.js

You can call .prop("tagName"). Examples:

jQuery("<a>").prop("tagName"); //==> "A"
jQuery("<h1>").prop("tagName"); //==> "H1"
jQuery("<coolTagName999>").prop("tagName"); //==> "COOLTAGNAME999"

If writing out .prop("tagName") is tedious, you can create a custom function like so:

jQuery.fn.tagName = function() {
  return this.prop("tagName");
};

Examples:

jQuery("<a>").tagName(); //==> "A"
jQuery("<h1>").tagName(); //==> "H1"
jQuery("<coolTagName999>").tagName(); //==> "COOLTAGNAME999"

Note that tag names are, by convention, returned CAPITALIZED. If you want the returned tag name to be all lowercase, you can edit the custom function like so:

jQuery.fn.tagNameLowerCase = function() {
  return this.prop("tagName").toLowerCase();
};

Examples:

jQuery("<a>").tagNameLowerCase(); //==> "a"
jQuery("<h1>").tagNameLowerCase(); //==> "h1"
jQuery("<coolTagName999>").tagNameLowerCase(); //==> "cooltagname999"

For most of the time, I use decimal(9,2) which takes the least storage (5 bytes) in sql decimal type.

Precision => Storage bytes

• 1 - 9 => 5
• 10-19 => 9
• 20-28 => 13
• 29-38 => 17

It can store from 0 up to 9 999 999.99 (7 digit infront + 2 digit behind decimal point = total 9 digit), which is big enough for most of the values.

Don't forget about fragmentation. If you have a lot of traffic, your pools can be fragmented and even if you have several MB free, there could be no block larger than 4KB. Check size of largest free block with a query like:

 select
  '0 (<140)' BUCKET, KSMCHCLS, KSMCHIDX,
  10*trunc(KSMCHSIZ/10) "From",
  count(*) "Count" ,
  max(KSMCHSIZ) "Biggest",
  trunc(avg(KSMCHSIZ)) "AvgSize",
  trunc(sum(KSMCHSIZ)) "Total"
from
  x$ksmsp
where
  KSMCHSIZ<140
and
  KSMCHCLS='free'
group by
  KSMCHCLS, KSMCHIDX, 10*trunc(KSMCHSIZ/10)
UNION ALL
select
  '1 (140-267)' BUCKET,
  KSMCHCLS,
  KSMCHIDX,
  20*trunc(KSMCHSIZ/20) ,
  count(*) ,
  max(KSMCHSIZ) ,
  trunc(avg(KSMCHSIZ)) "AvgSize",
  trunc(sum(KSMCHSIZ)) "Total"
from
  x$ksmsp
where
  KSMCHSIZ between 140 and 267
and
  KSMCHCLS='free'
group by
  KSMCHCLS, KSMCHIDX, 20*trunc(KSMCHSIZ/20)
UNION ALL
select
  '2 (268-523)' BUCKET,
  KSMCHCLS,
  KSMCHIDX,
  50*trunc(KSMCHSIZ/50) ,
  count(*) ,
  max(KSMCHSIZ) ,
  trunc(avg(KSMCHSIZ)) "AvgSize",
  trunc(sum(KSMCHSIZ)) "Total"
from
  x$ksmsp
where
  KSMCHSIZ between 268 and 523
and
  KSMCHCLS='free'
group by
  KSMCHCLS, KSMCHIDX, 50*trunc(KSMCHSIZ/50)
UNION ALL
select
  '3-5 (524-4107)' BUCKET,
  KSMCHCLS,
  KSMCHIDX,
  500*trunc(KSMCHSIZ/500) ,
  count(*) ,
  max(KSMCHSIZ) ,
  trunc(avg(KSMCHSIZ)) "AvgSize",
  trunc(sum(KSMCHSIZ)) "Total"
from
  x$ksmsp
where
  KSMCHSIZ between 524 and 4107
and
  KSMCHCLS='free'
group by
  KSMCHCLS, KSMCHIDX, 500*trunc(KSMCHSIZ/500)
UNION ALL
select

  KSMCHCLS,
  KSMCHIDX,
  1000*trunc(KSMCHSIZ/1000) ,
  count(*) ,
  max(KSMCHSIZ) ,
  trunc(avg(KSMCHSIZ)) "AvgSize",
  trunc(sum(KSMCHSIZ)) "Total"
from
  x$ksmsp
where
  KSMCHSIZ >= 4108
and
  KSMCHCLS='free'
group by
  KSMCHCLS, KSMCHIDX, 1000*trunc(KSMCHSIZ/1000);

Code from

You could use the following, provided String s is the string you want to process.

Map<Character,Integer> map = new HashMap<Character,Integer>();
for (int i = 0; i < s.length(); i++) {
  char c = s.charAt(i);
  if (map.containsKey(c)) {
    int cnt = map.get(c);
    map.put(c, ++cnt);
  } else {
    map.put(c, 1);
  }
}

Note, it will count all of the chars, not only letters.

You can achieve by doing below way.. just add a condition by adding bracket if(!(condition with instanceOf)) with the whole condition by adding ! operator at the start just the way mentioned in below code snippets.

if(!(str instanceof String)) { /* do Something */ } // COMPILATION WORK

instead of

if(str !instanceof String) { /* do Something */ } // COMPILATION FAIL

Here's a different approach. The heart of it was created by turning on the Macro Recorder and filtering the columns per your specifications. Then there's a bit of code to copy the results. It will run faster than looping through each row and column:

Sub FilterAndCopy()
Dim LastRow As Long

Sheets("Sheet2").UsedRange.Offset(0).ClearContents
With Worksheets("Sheet1")
    .Range("$A:$E").AutoFilter
    .Range("$A:$E").AutoFilter field:=1, Criteria1:="#N/A"
    .Range("$A:$E").AutoFilter field:=2, Criteria1:="=String1", Operator:=xlOr, Criteria2:="=string2"
    .Range("$A:$E").AutoFilter field:=3, Criteria1:=">0"
    .Range("$A:$E").AutoFilter field:=5, Criteria1:="Number"
    LastRow = .Range("A" & .Rows.Count).End(xlUp).Row
    .Range("A1:A" & LastRow).SpecialCells(xlCellTypeVisible).EntireRow.Copy _
            Destination:=Sheets("Sheet2").Range("A1")
End With
End Sub

As a side note, your code has more loops and counter variables than necessary. You wouldn't need to loop through the columns, just through the rows. You'd then check the various cells of interest in that row, much like you did.

You need to start the SQL Server manually. Press

windows + R

type

sqlservermanager12.msc

right click ->Start

Service configuration does not display SQL Server?

I know this is an old question but I just want to comment here: To any extent email addresses ARE case sensitive, most users would be "very unwise" to actively use an email address that requires capitals. They would soon stop using the address because they'd be missing a lot of their mail. (Unless they have a specific reason to make things difficult, and they expect mail only from specific senders they know.)

That's because imperfect humans as well as imperfect software exist, (Surprise!) which will assume all email is lowercase, and for this reason these humans and software will send messages using a "lower cased version" of the address regardless of how it was provided to them. If the recipient is unable to receive such messages, it won't be long before they notice they're missing a lot, and switch to a lowercase-only email address, or get their server set up to be case-insensitive.

You may like to try something like this which covers all the bases, including not relying on whitespace after the number:

>>> import re
>>> numeric_const_pattern = r"""
...     [-+]? # optional sign
...     (?:
...         (?: \d* \. \d+ ) # .1 .12 .123 etc 9.1 etc 98.1 etc
...         |
...         (?: \d+ \.? ) # 1. 12. 123. etc 1 12 123 etc
...     )
...     # followed by optional exponent part if desired
...     (?: [Ee] [+-]? \d+ ) ?
...     """
>>> rx = re.compile(numeric_const_pattern, re.VERBOSE)
>>> rx.findall(".1 .12 9.1 98.1 1. 12. 1 12")
['.1', '.12', '9.1', '98.1', '1.', '12.', '1', '12']
>>> rx.findall("-1 +1 2e9 +2E+09 -2e-9")
['-1', '+1', '2e9', '+2E+09', '-2e-9']
>>> rx.findall("current level: -2.03e+99db")
['-2.03e+99']
>>>

For easy copy-pasting:

numeric_const_pattern = '[-+]? (?: (?: \d* \. \d+ ) | (?: \d+ \.? ) )(?: [Ee] [+-]? \d+ ) ?'
rx = re.compile(numeric_const_pattern, re.VERBOSE)
rx.findall("Some example: Jr. it. was .23 between 2.3 and 42.31 seconds")

In your TS Definition file, e.g. typings.d.ts`, you can add this line:

declare module "*.json" {
const value: any;
export default value;
}

Then add this in your typescript(.ts) file:-

import * as data from './colors.json';
const word = (<any>data).name;

You need to remove the object from your data array before you call deleteRowsAtIndexPaths:withRowAnimation:. So, your code should look like this:

// Editing of rows is enabled
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
    if (editingStyle == UITableViewCellEditingStyleDelete) {

        //when delete is tapped
        [currentCart removeObjectAtIndex:indexPath.row];

        [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade];
    }
}

You can also simplify your code a little by using the array creation shortcut @[]:

[tableView deleteRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationFade];

Why not call the $('.input-group.date').datepicker("remove"); when the select statement is changed then set your datepicker view then call the $('.input-group.date').datepicker("update");

you should use "bAutoWidth" property of datatable and give width to each td/column in %

 $(".table").dataTable({"bAutoWidth": false , 
aoColumns : [
      { "sWidth": "15%"},
      { "sWidth": "15%"},
      { "sWidth": "15%"},
      { "sWidth": "15%"},
      { "sWidth": "15%"},
      { "sWidth": "15%"},
      { "sWidth": "10%"},
    ]
});

Hope this will help.

One command and does not use the destructive git reset command:

GIT_SEQUENCE_EDITOR="sed -i 's/pick/d/'" git rebase -i HEAD~ --autostash

It simply drops the commit, putting you back exactly in the state before the cherry-pick even if you had local changes.

To send mail through SQL Server we need to set up DB mail profile we can either use T-SQl or SQL Database mail option in sql server to create profile. After below code is used to send mail through query or stored procedure.

Use below link to create DB mail profile

Use the convert function.

SELECT CONVERT(varchar(10), field_name) FROM table_name

This Answer should work in most situations. Notice however how the filenames are stored in the tar file as, for example, ./file1 rather than just file1. I found that this caused problems when using this method to manipulate tarballs used as package files in BuildRoot.

One solution is to use some Bash globs to list all files except for .. like this:

tar -C my_dir -zcvf my_dir.tar.gz .[^.]* ..?* *

This is a trick I learnt from this answer.

Now tar will return an error if there are no files matching ..?* or .[^.]* , but it will still work. If the error is a problem (you are checking for success in a script), this works:

shopt -s nullglob
tar -C my_dir -zcvf my_dir.tar.gz .[^.]* ..?* *
shopt -u nullglob

Though now we are messing with shell options, we might decide that it is neater to have * match hidden files:

shopt -s dotglob
tar -C my_dir -zcvf my_dir.tar.gz *
shopt -u dotglob

This might not work where your shell globs * in the current directory, so alternatively, use:

shopt -s dotglob
cd my_dir
tar -zcvf ../my_dir.tar.gz *
cd ..
shopt -u dotglob

Just like SQL, Hive supports BETWEEN operator for more concise statement:

SELECT *
  FROM your_table
  WHERE your_date_column BETWEEN '2010-09-01' AND '2013-08-31';

You can do it using javascript. Grab the value of the form field in your submit function, parse out the extension.

You can start with something like this:

<form name="someform"enctype="multipart/form-data" action="uploader.php" method="POST">
<input type=file name="file1" />
<input type=button onclick="val()" value="xxxx" />
</form>
<script>
function val() {
    alert(document.someform.file1.value)
}
</script>

I agree with alexmac - do it server-side as well.

You're applying your class to the <a> elements, which aren't siblings because they're each enclosed in an <li> element. You need to move up the tree to the parent <li> and find the ` elements in the siblings at that level.

$('#menu li a').on('click', function(){
$(this).addClass('current').parent().siblings().find('a').removeClass('current');
});

In Android Studio 3.0 and Above

As described here

Note: The Run button builds an APK with testOnly="true", which means the APK can only be installed via adb (which Android Studio uses). If you want a debuggable APK that people can install without adb, select your debug variant and click Build Bundle(s) / APK(s) > Build APK(s).

Add android:testOnly="false" inside Application tag in AndroidManifest.xml

Reference: https://commonsware.com/blog/2017/10/31/android-studio-3p0-flag-test-only.html

Typically you'll need cookies to log into a site, which means cookielib, urllib and urllib2. Here's a class which I wrote back when I was playing Facebook web games:

import cookielib
import urllib
import urllib2

# set these to whatever your fb account is
fb_username = "[email protected]"
fb_password = "secretpassword"

class WebGamePlayer(object):

    def __init__(self, login, password):
        """ Start up... """
        self.login = login
        self.password = password

        self.cj = cookielib.CookieJar()
        self.opener = urllib2.build_opener(
            urllib2.HTTPRedirectHandler(),
            urllib2.HTTPHandler(debuglevel=0),
            urllib2.HTTPSHandler(debuglevel=0),
            urllib2.HTTPCookieProcessor(self.cj)
        )
        self.opener.addheaders = [
            ('User-agent', ('Mozilla/4.0 (compatible; MSIE 6.0; '
                           'Windows NT 5.2; .NET CLR 1.1.4322)'))
        ]

        # need this twice - once to set cookies, once to log in...
        self.loginToFacebook()
        self.loginToFacebook()

    def loginToFacebook(self):
        """
        Handle login. This should populate our cookie jar.
        """
        login_data = urllib.urlencode({
            'email' : self.login,
            'pass' : self.password,
        })
        response = self.opener.open("https://login.facebook.com/login.php", login_data)
        return ''.join(response.readlines())

You won't necessarily need the HTTPS or Redirect handlers, but they don't hurt, and it makes the opener much more robust. You also might not need cookies, but it's hard to tell just from the form that you've posted. I suspect that you might, purely from the 'Remember me' input that's been commented out.

No need too these. Just simply add div id to href of a < a > tag

<li><a id = "aboutlink" href="#about">auck</a></li>

Just like that.

<?php
$date1=date_create("2013-03-15");
$date2=date_create("2013-12-12");
$diff=date_diff($date1,$date2);
echo $diff->format("%R%a days");
?>

used the above code very simple. Thanks.

Extension to ollyc recipe :

CREATE VIEW foreign_keys_view AS
SELECT
    tc.table_name, kcu.column_name,
    ccu.table_name AS foreign_table_name,
    ccu.column_name AS foreign_column_name
FROM
    information_schema.table_constraints AS tc
    JOIN information_schema.key_column_usage 
        AS kcu ON tc.constraint_name = kcu.constraint_name
    JOIN information_schema.constraint_column_usage 
        AS ccu ON ccu.constraint_name = tc.constraint_name
WHERE constraint_type = 'FOREIGN KEY';

Then:

SELECT * FROM foreign_keys_view WHERE table_name='YourTableNameHere';

In a batch file solution

for /R c:\source %%f in (*.xml) do copy %%f x:\destination\

The code works as such;

for each file for in directory c:\source and subdirectories /R that match pattern (\*.xml) put the file name in variable %%f, then for each file do copy file copy %%f to destination x:\\destination\\

Just tested it here on my Windows XP computer and it worked like a treat for me. But I typed it into command prompt so I used the single %f variable name version, as described in the linked question above.

String formattedStr=unformattedStr;
formattedStr=formattedStr.trim().replaceAll("\\s+", " ");

It's amazing what the Framework already does for us.

List<int> myValues;
string csv = String.Join(",", myValues.Select(x => x.ToString()).ToArray());

For the general case:

IEnumerable<T> myList;
string csv = String.Join(",", myList.Select(x => x.ToString()).ToArray());

As you can see, it's effectively no different. Beware that you might need to actually wrap x.ToString() in quotes (i.e., "\"" + x.ToString() + "\"") in case x.ToString() contains commas.

For an interesting read on a slight variant of this: see Comma Quibbling on Eric Lippert's blog.

Note: This was written before .NET 4.0 was officially released. Now we can just say

IEnumerable<T> sequence;
string csv = String.Join(",", sequence);

using the overload String.Join<T>(string, IEnumerable<T>). This method will automatically project each element x to x.ToString().

Below code will fix root = tk.Tk() to its size before it was called:

root.resizable(False, False)

Apply DataAnnotation like:

[DisplayFormat(DataFormatString = "{0:MMM dd, yyyy}")]

"HTTP 415 Unsupported Media Type response" stems from Content-Type in header of your request. for example in javascript by axios:

Axios({
            method: 'post',
            headers: { 'Content-Type': 'application/json'},
            url: '/',
            data: data,  // an object u want to send
          }).then(function (response) {
            console.log(response);
          });

Here is another way:

df['rnd'] = np.random.rand(len(df)) df = df.sort_values(by='rnd', inplace=True).drop('rnd', axis=1)

If you just want to get the current UNIX timestamp I'd just use time()

$timestamp = time(); 

The spread operator is kinda cool.

this.results = [ ...this.results, ...data.results];

The spread operator allows you to easily place an expanded version of an array into another array.

You can read about spread operator here.

the below may be help.

You just have to use class="row-eq-height" with your class="row" to get equal height columns for previous bootstrap versions.

but with bootstrap 4 this comes natively.

check this link --http://getbootstrap.com.vn/examples/equal-height-columns/

@robertc has it right, but you also need to notice that svg, #container causes the svg to be scaled exponentially for anything but 100% (once for #container and once for svg).

In other words, if I applied 50% h/w to both elements, it's actually 50% of 50%, or .5 * .5, which equals .25, or 25% scale.

One selector works fine when used as @robertc suggests.

svg {
  width:50%;
  height:50%;
}

This will remove only the trailing characters of your choice.

func trimRight(theString: String, charSet: NSCharacterSet) -> String {

    var newString = theString

    while String(newString.characters.last).rangeOfCharacterFromSet(charSet) != nil {
        newString = String(newString.characters.dropLast())
    }

    return newString
}

table {
    border-collapse: collapse;
}

td {
    padding-top: .5em;
    padding-bottom: .5em;
}

The cells won't react to anything unless you set the border-collapse first. You can also add borders to TR elements once that's set (among other things.)

If this is for layout, I'd move to using DIVs and more up-to-date layout techniques, but if this is tabular data, knock yourself out. I still make heavy use of tables in my web applications for data.

You do not need it.

If your action has the HttpPost attribute, then you do not need to bother with setting the JsonRequestBehavior and use the overload without it. There is an overload for each method without the JsonRequestBehavior enum. Here they are:

Without JsonRequestBehavior

protected internal JsonResult Json(object data);
protected internal JsonResult Json(object data, string contentType);
protected internal virtual JsonResult Json(object data, string contentType, Encoding contentEncoding);

With JsonRequestBehavior

protected internal JsonResult Json(object data, JsonRequestBehavior behavior);
protected internal JsonResult Json(object data, string contentType, 
                                   JsonRequestBehavior behavior);
protected internal virtual JsonResult Json(object data, string contentType, 
    Encoding contentEncoding, JsonRequestBehavior behavior);

Assume that you've defined do_something as a function, and you'd like to perform it N times. Maybe you can try the following:

todos = [do_something] * N  
for doit in todos:  
    doit()

You can do it in single line, for any object type not just Map.

(Since I use Gson quite liberally, I am sharing a Gson based approach)

Gson gson = new Gson();    
Map<Object,Object> attributes = gson.fromJson(gson.toJson(value),Map.class);

What it does is:

1. gson.toJson(value) will serialize your object into its equivalent Json representation.
2. gson.fromJson will convert the Json string to specified object. (in this example - Map)

There are 2 advantages with this approach:

1. The flexibility to pass an Object instead of String to toJson method.
2. You can use this single line to convert to any object even your own declared objects.

To get the appID you could use the following line of code:

var applicationId = ((GuidAttribute)typeof(Program).Assembly.GetCustomAttributes(typeof(GuidAttribute), true)[0]).Value;

For this you need to include the System.Runtime.InteropServices;

3 things you have to do, if you are doing it locally:

in php.ini or php.cfg of your php installation

post_max_size=500M

upload_max_filesize=500M

memory_limit=900M

or set other values. Restart Apache.

Use php big dump tool its best ever i have seen. its free and opensource

For those who want to use simpleUML in Android Studio and having issues in running SimpleUML.

First download simpleUML jar from here https://plugins.jetbrains.com/plugin/4946-simpleumlce

Now follow the below steps.

Step 1:

Click on File and go to Settings (File ? Settings)

Step 2

Select Plugins from Left Panel and click Install plugin from disk

Step 3:

Locate the SimpleUML jar file and select it.

Step 4:

Now Restart Android Studio (File ? Invalidate Caches/Restart ? Just Restart)

Step 5:

After you restart Right Click the Package name and Select New Diagram or Add to simpleUML Diagram ? New Diagram.

Step 6:

Set a file name and create UML file. I created with name NewDiagram

Step 7:

Now Right Click the Package name and Select the file you created. In my case it was NewDiagram

Step 8:

All files are stacked on top of one another. You can just drag and drop them and set a hierarchy.

Like this below, you can drag these classes

You typically restore purchases with this code:

[[SKPaymentQueue defaultQueue] restoreCompletedTransactions];

It will reinvoke -paymentQueue:updatedTransactions on the observer(s) for the purchased items. This is useful for users who reinstall the app after deletion or install it on a different device.

Not all types of In-App purchases can be restored.

JavaScript works with the number of milliseconds since the epoch whereas most other languages work with the seconds. You could work with milliseconds but as soon as you pass a value to say PHP, the PHP native functions will probably fail. So to be sure I always use the seconds, not milliseconds.

This will give you a Unix timestamp (in seconds):

var unix = Math.round(+new Date()/1000);

This will give you the milliseconds since the epoch (not Unix timestamp):

var milliseconds = new Date().getTime();

To stop executing java code just use this command:

    System.exit(1);

After this command java stops immediately!

for example:

    int i = 5;
    if (i == 5) {
       System.out.println("All is fine...java programm executes without problem");
    } else {
       System.out.println("ERROR occured :::: java programm has stopped!!!");
       System.exit(1);
    }

 var myString = 'sample String';   var length = myString.length ;

first you need to defined a keypressed handler or some kind of a event trigger to listen , btw , getting the length is really simple like mentioned above

For the full-screen responsive background image cover

<div class="full-screen">

</div>

CSS

.full-screen{
    background-image: url("img_girl.jpg");
    height: 100%; 
    background-position: center;
    background-repeat: no-repeat;
    background-size: cover;
}

I found

dmesg | grep tty

doing the job.

It seems to work if you use

div#scrollable {
    overflow-y: scroll;
    height: 100%;
}

and add padding-bottom: 60px to div.sidebar.

For example: http://jsfiddle.net/AKL35/6/

However, I am unsure why it must be 60px.

Also, you missed the f from overflow-y: scroll;

I did sudo chmod 777 -R . to be able to change the permissions. Without sudo, it wouldn't work, giving me the same error as running other commands.

Now you can do svn update or whatever, without having to scrap your entire directory and recreating it. This is especially helpful, since your IDE or text editor may already have certain tabs open, or have syncing problems. You don't need to scrap and replace your working directory with this method.

PHP mail() command does not support authentication. Your options:

There is a fourth way using Handler

new Handler().post(new Runnable() {
    @Override
    public void run() {
        // Code here will run in UI thread
    }
});

Entirely from javacoffeebreak.com/faq/faq0012.html

A low priority thread takes care of garbage collection automatically for the user. During idle time, the thread may be called upon, and it can begin to free memory previously allocated to an object in Java. But don't worry - it won't delete your objects on you!

When there are no references to an object, it becomes fair game for the garbage collector. Rather than calling some routine (like free in C++), you simply assign all references to the object to null, or assign a new class to the reference.

Example :

public static void main(String args[])
{
  // Instantiate a large memory using class
  MyLargeMemoryUsingClass myClass = new MyLargeMemoryUsingClass(8192);

  // Do some work
  for ( .............. )
  {
      // Do some processing on myClass
  }

  // Clear reference to myClass
  myClass = null;

  // Continue processing, safe in the knowledge
  // that the garbage collector will reclaim myClass
}

If your code is about to request a large amount of memory, you may want to request the garbage collector begin reclaiming space, rather than allowing it to do so as a low-priority thread. To do this, add the following to your code

System.gc();

The garbage collector will attempt to reclaim free space, and your application can continue executing, with as much memory reclaimed as possible (memory fragmentation issues may apply on certain platforms).

You can override the IIS default document setting using the web.config

<system.webServer>
    <defaultDocument>
      <files>
        <clear />
        <add value="DefaultPageToBeSet.aspx" />
      </files>
    </defaultDocument>
  </system.webServer>

testCompile group: 'org.hamcrest', name: 'hamcrest-library', version: '2.1'

HttpUtil being deprecated, this is the correct method

String requestURL = url.toString();

=A1/(24*60*60) + DATE(1970;1;1) should work with seconds.

=(A1/86400/1000)+25569 if your time is in milliseconds, so dividing by 1000 gives use the correct date

Don't forget to set the type to Date on your output cell. I tried it with this date: 1504865618099 which is equal to 8-09-17 10:13.

You just compile it. In the bin\Release (or bin\Debug) folder, the .exe will be in there.

If you're asking how to make an executable which does not rely on the .NET framework at all, then that's a lot harder and you'll need to purchase something like RemoteSoft's Salamader. In general, it's not really worth the bother: Windows Vista comes with .NET framework 2.0 pre-installed already so if you're worried about that, you can just target the 2.0 framework (then only XP users would have to install the framework).

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

In addition to the other answers, the ES2015 syntax blends seamlessly with promises, reducing even more boilerplate code:

// Sequentially:
api1()
  .then(r1 => api2(r1))
  .then(r2 => api3(r2))
  .then(r3 => {
      // Done
  });

// Parallel:
Promise.all([
    api1(),
    api2(),
    api3()
]).then(([r1, r2, r3]) => {
    // Done
});

JavaScript syntax 101. Here is a function declaration:

function foo() {}

Note that there's no semicolon: this is just a function declaration. You would need an invocation, foo(), to actually run the function.

Now, when we add the seemingly innocuous exclamation mark: !function foo() {} it turns it into an expression. It is now a function expression.

The ! alone doesn't invoke the function, of course, but we can now put () at the end: !function foo() {}() which has higher precedence than ! and instantly calls the function.

So what the author is doing is saving a byte per function expression; a more readable way of writing it would be this:

(function(){})();

Lastly, ! makes the expression return true. This is because by default all immediately invoked function expressions (IIFE) return undefined, which leaves us with !undefined which is true. Not particularly useful.

Could someone explain to me, how to call the move method with the variable RIGHT

>>> myMissile = MissileDevice(myBattery)  # looks like you need a battery, don't know what that is, you figure it out.
>>> myMissile.move(MissileDevice.RIGHT)

If you have programmed in any other language with classes, besides python, this sort of thing

class Foo:
    bar = "baz"

is probably unfamiliar. In python, the class is a factory for objects, but it is itself an object; and variables defined in its scope are attached to the class, not the instances returned by the class. to refer to bar, above, you can just call it Foo.bar; you can also access class attributes through instances of the class, like Foo().bar.

Im utterly baffled about what 'self' refers too,

>>> class Foo:
...     def quux(self):
...         print self
...         print self.bar
...     bar = 'baz'
...
>>> Foo.quux
<unbound method Foo.quux>
>>> Foo.bar
'baz'
>>> f = Foo()
>>> f.bar
'baz'
>>> f
<__main__.Foo instance at 0x0286A058>
>>> f.quux
<bound method Foo.quux of <__main__.Foo instance at 0x0286A058>>
>>> f.quux()
<__main__.Foo instance at 0x0286A058>
baz
>>>

When you acecss an attribute on a python object, the interpreter will notice, when the looked up attribute was on the class, and is a function, that it should return a "bound" method instead of the function itself. All this does is arrange for the instance to be passed as the first argument.

You have to connect your client socket to the remote ServerSocket. Instead of

Socket clientSocket = new Socket("localhost", 5000);

do

Socket clientSocket = new Socket(serverName, 5000);

The client must connect to serverName which should match the name or IP of the box on which your ServerSocket was instantiated (the name must be reachable from the client machine). BTW: It's not the name that is important, it's all about IP addresses...

It's been quite a few years since this question was last answered. React introduced "Hooks" back in 2017, and "keyCode" has been deprecated.

Now we can write this:

  useEffect(() => {
    const listener = event => {
      if (event.code === "Enter" || event.code === "NumpadEnter") {
        console.log("Enter key was pressed. Run your function.");
        // callMyFunction();
      }
    };
    document.addEventListener("keydown", listener);
    return () => {
      document.removeEventListener("keydown", listener);
    };
  }, []);

This registers a listener on the keydown event, when the component is loaded for the first time. It removes the event listener when the component is destroyed.

Put this in style

 select[readonly] option, select[readonly] optgroup {
        display: none;
    }

You cannot save it as local file without using server side logic. But if that fits your needs, you could look at local storage of html5 or us a javascript plugin as jStorage

Try Like this.

For Inserting into DB

$db = mysqli_connect("localhost","root","","DbName"); //keep your db name
$image = addslashes(file_get_contents($_FILES['images']['tmp_name']));
//you keep your column name setting for insertion. I keep image type Blob.
$query = "INSERT INTO products (id,image) VALUES('','$image')";  
$qry = mysqli_query($db, $query);

For Accessing image From Blob

$db = mysqli_connect("localhost","root","","DbName"); //keep your db name
$sql = "SELECT * FROM products WHERE id = $id";
$sth = $db->query($sql);
$result=mysqli_fetch_array($sth);
echo '<img src="data:image/jpeg;base64,'.base64_encode( $result['image'] ).'"/>';

Hope It will help you.

Thanks.

You can use replace instead of gsub.

"hello _there_".replace(/_(.*?)_/g, "<div>\$1</div>")

This error message means that you are attempting to use Python 3 to follow an example or run a program that uses the Python 2 print statement:

print "Hello, World!"

The statement above does not work in Python 3. In Python 3 you need to add parentheses around the value to be printed:

print("Hello, World!")

“SyntaxError: Missing parentheses in call to 'print'” is a new error message that was added in Python 3.4.2 primarily to help users that are trying to follow a Python 2 tutorial while running Python 3.

In Python 3, printing values changed from being a distinct statement to being an ordinary function call, so it now needs parentheses:

>>> print("Hello, World!")
Hello, World!

In earlier versions of Python 3, the interpreter just reports a generic syntax error, without providing any useful hints as to what might be going wrong:

>>> print "Hello, World!"
  File "<stdin>", line 1
    print "Hello, World!"
                        ^
SyntaxError: invalid syntax

As for why print became an ordinary function in Python 3, that didn't relate to the basic form of the statement, but rather to how you did more complicated things like printing multiple items to stderr with a trailing space rather than ending the line.

In Python 2:

>>> import sys
>>> print >> sys.stderr, 1, 2, 3,; print >> sys.stderr, 4, 5, 6
1 2 3 4 5 6

In Python 3:

>>> import sys
>>> print(1, 2, 3, file=sys.stderr, end=" "); print(4, 5, 6, file=sys.stderr)
1 2 3 4 5 6

Starting with the Python 3.6.3 release in September 2017, some error messages related to the Python 2.x print syntax have been updated to recommend their Python 3.x counterparts:

>>> print "Hello!"
  File "<stdin>", line 1
    print "Hello!"
                 ^
SyntaxError: Missing parentheses in call to 'print'. Did you mean print("Hello!")?

Since the "Missing parentheses in call to print" case is a compile time syntax error and hence has access to the raw source code, it's able to include the full text on the rest of the line in the suggested replacement. However, it doesn't currently try to work out the appropriate quotes to place around that expression (that's not impossible, just sufficiently complicated that it hasn't been done).

The TypeError raised for the right shift operator has also been customised:

>>> print >> sys.stderr
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: unsupported operand type(s) for >>: 'builtin_function_or_method' and '_io.TextIOWrapper'. Did you mean "print(<message>, file=<output_stream>)"?

Since this error is raised when the code runs, rather than when it is compiled, it doesn't have access to the raw source code, and hence uses meta-variables (<message> and <output_stream>) in the suggested replacement expression instead of whatever the user actually typed. Unlike the syntax error case, it's straightforward to place quotes around the Python expression in the custom right shift error message.

use form shown event and set

MyTextBox.Focus();

Alternatively, you can create a new dataframe (or overwrite the current one, as the example below) so you do not need to use of any external package. However this way may not be efficient with huge dataframes.

df <- data.frame(names = row.names(df), df)

You can use urllib2 to make the HTTP requests, and then you'll have web content.

You can get it like this:

import urllib2
response = urllib2.urlopen('http://example.com')
html = response.read()

Beautiful Soup is a python HTML parser that is supposed to be good for screen scraping.

In particular, here is their tutorial on parsing an HTML document.

Good luck!

The state is the origin of truth, where your data lives. You can say the state manifests itself via props.

Providing props to components is what keeps your UI in sync with your data. A component is really just a function that returns markup.

Given the same props (data for it to display) it will always produce the same markup.

So the props are like the pipelines that carry the data from the origin to the functional components.

Use root tag as shape instead of selector in your shape.xml file, and it will resolve your problem!

If you are familiar with gcc, as you indicated in the question, you can install MinGW, which will set a linux-like compile environment in Win7. Otherwise, Visual Studio 2010 Express is the best choice.

I tested both requests-futures and grequests. Grequests is faster but brings monkey patching and additional problems with dependencies. requests-futures is several times slower than grequests. I decided to write my own and simply wrapped requests into ThreadPoolExecutor and it was almost as fast as grequests, but without external dependencies.

import requests
import concurrent.futures

def get_urls():
    return ["url1","url2"]

def load_url(url, timeout):
    return requests.get(url, timeout = timeout)

with concurrent.futures.ThreadPoolExecutor(max_workers=20) as executor:

    future_to_url = {executor.submit(load_url, url, 10): url for url in     get_urls()}
    for future in concurrent.futures.as_completed(future_to_url):
        url = future_to_url[future]
        try:
            data = future.result()
        except Exception as exc:
            resp_err = resp_err + 1
        else:
            resp_ok = resp_ok + 1

Ok - for me the source of the problem was in serialisation/deserialisation. The object that was being sent and received was as follows where the code is submitted and the code and maskedPhoneNumber is returned.

@ApiObject(description = "What the object is for.")
@JsonIgnoreProperties(ignoreUnknown = true)
public class CodeVerification {

    @ApiObjectField(description = "The code which is to be verified.")
    @NotBlank(message = "mandatory")
    private final String code;

    @ApiObjectField(description = "The masked mobile phone number to which the code was verfied against.")
    private final String maskedMobileNumber;

    public codeVerification(@JsonProperty("code") String code, String maskedMobileNumber) {
        this.code = code;
        this.maskedMobileNumber = maskedMobileNumber;
    }

    public String getcode() {
        return code;
    }

    public String getMaskedMobileNumber() {
        return maskedMobileNumber;
    }
}

The problem was that I didn't have a JsonProperty defined for the maskedMobileNumber in the constructor. i.e. Constructor should have been

public codeVerification(@JsonProperty("code") String code, @JsonProperty("maskedMobileNumber") String maskedMobileNumber) {
    this.code = code;
    this.maskedMobileNumber = maskedMobileNumber;
}

i assume you are working with nullable datatypes, you can do something like this:

var t = things.Where(x => x!=null && x.Value.ID == long.Parse(options.ID)).FirstOrDefault();
var res = t == null ? "" : t.Value;

Here is my solutions; It is my getView() in BaseAdapter subclass:

public View getView(int position, View convertView, ViewGroup parent)
{
    if(convertView==null)
    {
        convertView=inflater.inflate(R.layout.list_view, parent,false);
        System.out.println("In");
    }
    convertView.setMinimumHeight(100);
    return convertView;
}

Here i have set ListItem's minimum height to 100;

In oracle-based products you may use the following statement:

update table set interfaceID=RowNum where condition;

To drop constraint for multiple columns:

declare @table_name nvarchar(256)

declare @Command nvarchar(max) = ''

set @table_name = N'ATableName'

select @Command = @Command + 'ALTER TABLE ' + @table_name + ' drop constraint ' + d.name + CHAR(10)+ CHAR(13)
from sys.tables t
join sys.default_constraints d on d.parent_object_id = t.object_id
join sys.columns c on c.object_id = t.object_id
     and c.column_id = d.parent_column_id
where t.name = @table_name and c.name in ('column1','column2','column3')

--print @Command

execute (@Command)

Ok after doing reverse engineering and a little pixie dust of reflection, one can do this operation on SelectedCells (at any point) to get all (regardless of selected on one row or many rows) the data from one to many selected cells:

MessageBox.Show(

string.Join(", ", myGrid.SelectedCells
                        .Select(cl => cl.Item.GetType()
                                             .GetProperty(cl.Column.SortMemberPath)
                                             .GetValue(cl.Item, null)))

               );

I tried this on text (string) fields only though a DateTime field should return a value the initiate ToString(). Also note that SortMemberPath is not the same as Header so that should always provide the proper property to reflect off of.

<DataGrid ItemsSource="{Binding MyData}"                      
          AutoGenerateColumns="True"
          Name="myGrid"
          IsReadOnly="True"
          SelectionUnit="Cell"
          SelectionMode="Extended">

As far as I know there is no option to create global configuration for java applications. You always create a duplicate of the configuration.

Also, if you are using PDE (for plugin development), you can create target platform using windows -> Preferences -> Plug-in development -> Target Platform. Edit has options for program/vm arguments.

Hope this helps

var a = A.parentNode.replaceChild(document.createElement("span"), A);

a is the replaced A element.

I found one plugin which can help to update all npm packages.

First, you need to install an npm-check-updates plugin.here is the link npm-check-updates

npm i -g npm-check-updates

So this utility is installed globally, you can invoke it by simply writing as follow.

1) ncu -u Here ncu is npm check updates.

2) npm install

So with these two commands, you can easily update npm packages.I hope this will help you to update packages easily.

Run the cmd as run as administrator this worked for me

Work with checkboxes using observables

You could even choose to use a behaviourSubject to utilize the power of observables so you can start a certain chain of reaction starting at the isChecked$ observable.

In your component.ts:

public isChecked$ = new BehaviorSubject(false);
toggleChecked() {
  this.isChecked$.next(!this.isChecked$.value)
}

In your template

<input type="checkbox" [checked]="isChecked$ | async" (change)="toggleChecked()">

Inside a GitLab CI pipeline the CI_JOB_TOKEN environment variable works for me:

git clone https://gitlab-ci-token:${CI_JOB_TOKEN}@gitlab.com/...

Source: Gitlab Docs

BTW, setting this variable in .gitlab-ci.yml helps to debug errors.

variables:
    CI_DEBUG_TRACE: "true"

You haven't posted the findvertex method, but Access Reading Violation with an offset like 0x00000048 means that the Vertex* f; in your getCost function is receiving null, and when trying to access the member adj in the null Vertex pointer (that is, in f), it is offsetting to adj (in this case, 72 bytes ( 0x48 bytes in decimal )), it's reading near the 0 or null memory address.

Doing a read like this violates Operating-System protected memory, and more importantly means whatever you're pointing at isn't a valid pointer. Make sure findvertex isn't returning null, or do a comparisong for null on f before using it to keep yourself sane (or use an assert):

assert( f != null ); // A good sanity check

EDIT:

If you have a map for doing something like a find, you can just use the map's find method to make sure the vertex exists:

Vertex* Graph::findvertex(string s)
{
    vmap::iterator itr = map1.find( s );
    if ( itr == map1.end() )
    {
        return NULL;
    }
    return itr->second;
}

Just make sure you're still careful to handle the error case where it does return NULL. Otherwise, you'll keep getting this access violation.

I don't recall the exact syntax, but you may set the table column to be case insensitive. But be careful because then you won't be able to match based on case anymore and if you WANT 'cool' to not match 'CoOl' it will no longer be possible.
