The issue turned out to be certificate-related. The WCF service called by the console app uses an X509 cert for authentication, which is installed on the servers that this script is hosted and run from.

On other servers, where the same services are consumed, the certificates were configured as follows:

winhttpcertcfg.exe -g -c LOCAL_MACHINE\My -s "certificate-name" -a "NETWORK SERVICE"

As they ran within the context of IIS. However, when the script was being run as it would in production, it's under the context of the user themselves. So, the script needed to be modified to the following:

winhttpcertcfg.exe -g -c LOCAL_MACHINE\My -s "certificate-name" -a "USERS"

Once that change was made, all was well. Thanks to everyone who offered assistance.

Convert the batch file to an exe. Try Bat To Exe Converter or Online Bat To Exe Converter, and choose the option to run it as a ghost application, i.e. no window.

an existing folder will FAIL with FileExists

Function FileExists(strFileName)
' Check if a file exists - returns True or False

use instead or in addition:

Function FolderExists(strFolderPath)
' Check if a path exists

Here is what you need to do...

Create a batch file with the following line

RMDIR /S %1

Save your batch file as Remove.bat and put it in C:\windows

Create the following registry key

HKEY_CLASSES_ROOT\Directory\shell\Remove Directory (RMDIR)

Launch regedit and update the default value HKEY_CLASSES_ROOT\Directory\shell\Remove Directory (RMDIR)\default with the following value

"c:\windows\REMOVE.bat" "%1"

Thats it! Now you can right click any directory and use the RMDIR function

You can use WScript.Arguments to access the arguments passed to your script.

Calling the script:

cscript.exe test.vbs "C:\temp\"

Inside your script:

Set File = FSO.OpenTextFile(WScript.Arguments(0) &"\test.txt", 2, True)

Don't forget to check if there actually has been an argument passed to your script. You can do so by checking the Count property:

if WScript.Arguments.Count = 0 then
    WScript.Echo "Missing parameters"
end if

If your script is over after you close the file then there is no need to set the variables to Nothing. The resources will be cleaned up automatically when the cscript.exe process terminates. Setting a variable to Nothing usually is only necessary if you explicitly want to free resources during the execution of your script. In that case, you would set variables which contain a reference to a COM object to Nothing, which would release the COM object before your script terminates. This is just a short answer to your bonus question, you will find more information in these related questions:

Is there a need to set Objects to Nothing inside VBA Functions

When must I set a variable to “Nothing” in VB6?

This is to do with JavaScript's + in operator - if a number and a string are "added" up, the number is converted into a string:

0 + 1; //1
'0' + 1; // '01'

To solve this, use the + unary operator, or use parseInt():

+'0' + 1; // 1
parseInt('0', 10) + 1; // 1

The unary + operator converts it into a number (however if it's a decimal it will retain the decimal places), and parseInt() is self-explanatory (converts into number, ignoring decimal places).

The second argument is necessary for parseInt() to use the correct base when leading 0s are placed:

parseInt('010'); // 8 in older browsers, 10 in newer browsers
parseInt('010', 10); // always 10 no matter what

There's also parseFloat() if you need to convert decimals in strings to their numeric value - + can do that too but it behaves slightly differently: that's another story though.

Override the handleIntent Method of the FirebaseMessageService works for me.

here the code in C# (Xamarin)

public override void HandleIntent(Intent intent)
{
    try
    {
        if (intent.Extras != null)
        {
            var builder = new RemoteMessage.Builder("MyFirebaseMessagingService");

            foreach (string key in intent.Extras.KeySet())
            {
                builder.AddData(key, intent.Extras.Get(key).ToString());
            }

            this.OnMessageReceived(builder.Build());
        }
        else
        {
            base.HandleIntent(intent);
        }
    }
    catch (Exception)
    {
        base.HandleIntent(intent);
    }
}

and thats the Code in Java

public void handleIntent(Intent intent)
{
    try
    {
        if (intent.getExtras() != null)
        {
            RemoteMessage.Builder builder = new RemoteMessage.Builder("MyFirebaseMessagingService");

            for (String key : intent.getExtras().keySet())
            {
                builder.addData(key, intent.getExtras().get(key).toString());
            }

            onMessageReceived(builder.build());
        }
        else
        {
            super.handleIntent(intent);
        }
    }
    catch (Exception e)
    {
        super.handleIntent(intent);
    }
}

Checkboxes are a control type designed for one purpose: to ensure valid entry of Boolean values.

In Access, there are two types:

1. 2-state -- can be checked or unchecked, but not Null. Values are True (checked) or False (unchecked). In Access and VBA, the value of True is -1 and the value of False is 0. For portability with environments that use 1 for True, you can always test for False or Not False, since False is the value 0 for all environments I know of.

2. 3-state -- like the 2-state, but can be Null. Clicking it cycles through True/False/Null. This is for binding to an integer field that allows Nulls. It is of no use with a Boolean field, since it can never be Null.

Minor quibble with the answers:

There is almost never a need to use the .Value property of an Access control, as it's the default property. These two are equivalent:

  ?Me!MyCheckBox.Value
  ?Me!MyCheckBox

The only gotcha here is that it's important to be careful that you don't create implicit references when testing the value of a checkbox. Instead of this:

  If Me!MyCheckBox Then

...write one of these options:

  If (Me!MyCheckBox) Then  ' forces evaluation of the control

  If Me!MyCheckBox = True Then

  If (Me!MyCheckBox = True) Then

  If (Me!MyCheckBox = Not False) Then

Likewise, when writing subroutines or functions that get values from a Boolean control, always declare your Boolean parameters as ByVal unless you actually want to manipulate the control. In that case, your parameter's data type should be an Access control and not a Boolean value. Anything else runs the risk of implicit references.

Last of all, if you set the value of a checkbox in code, you can actually set it to any number, not just 0 and -1, but any number other than 0 is treated as True (because it's Not False). While you might use that kind of thing in an HTML form, it's not proper UI design for an Access app, as there's no way for the user to be able to see what value is actually be stored in the control, which defeats the purpose of choosing it for editing your data.

const express = require('express');_x000D_
let app = express();_x000D_
app.use(express.json());

This app.use(express.json) will now let you read the incoming post JSON object

If you are using PyDev in Eclipse, its Ctrl0 and Ctrl9 for collapse all and uncollapse all respectively. Ctrl- and Ctrl= to collapse individual methods when your cursor is on the line of the method declaration.

As others mentioned, this is not the fastest nor most recommended solution. Marcosc's solution below is the way to go.

You can use eval:

var code = "this.f = function " + instance + "() {...}";
eval(code);

Go back in to where you added the jar. I believe its the libraries tab, I don't have Eclipse open but that sounds right. to the left of the jar file you added there should be an arrow pointing right, click that and 3 or 4 options expand, one of them being the source file of the library. Click on that and click edit(I think you can also double click it) then locate the file or folder on your hard disk, you probably have to click apply or okay and you're good to go, same with javadoc and i think the last one is native libraries. I don't pay much attention when I'm in there anymore if you couldn't tell. That's what you were asking, right?

I'm a bit late to the party but I wrote a custom view that let's you do this, by default it's set to entypo, but you can modify it to use any iconfont: check it out here: github.com/MarsVard/IconView

// edit the library is old and not supported anymore... new one here https://github.com/MarsVard/IonIconView

A simple solution is encapsulate code of button event in a function, and call it when you add TRs too:

 var i = 1;
$("#addbutton").click(function() {
  $("table tr:first").clone().find("input").each(function() {
    $(this).val('').attr({
      'id': function(_, id) {return id + i },
      'name': function(_, name) { return name + i },
      'value': ''               
    });
  }).end().appendTo("table");
  i++;

  applyRemoveEvent();  
});


function applyRemoveEvent(){
    $('button.removebutton').on('click',function() {
        alert("aa");
      $(this).closest( 'tr').remove();
      return false;
    });
};

applyRemoveEvent();

for eg. you may take

driver.get('https://www.naukri.com/')

since, it is a current window ,we can name it

main_page = driver.current_window_handle

if there are atleast 1 window popup except the current window,you may try this method and put if condition in break statement by hit n trial for the index

for handle in driver.window_handles:
    if handle != main_page:
        print(handle)
        login_page = handle
        break

driver.switch_to.window(login_page)

Now ,whatever the credentials you have to apply,provide after it is loggen in. Window will disappear, but you have to come to main page window and you are done

driver.switch_to.window(main_page)
sleep(10)

Just use

composer require {package/packagename}

like

composer require phpmailer/phpmailer

if the package is not in the vendor folder.. composer installs it and if the package exists, composer update package to the latest version.

height attribute has been deprecated in html 5. What I would do is create a border around the hr and increase the thickness of the border as such: hr style="border:solid 2px black;"

You can use Ansible stat module to register the file, and when module to apply the condition.

- name: Register file
      stat:
        path: "/tmp/test_file"
      register: file_path

- name: Create file if it doesn't exists
      file: 
        path: "/tmp/test_file"
        state: touch
      when: file_path.stat.exists == False

I know this is old but by far the easier solution is to just use

var temp = new Date("2010-08-17T12:09:36");

There is also this one:

hash = { foo: "bar", baz: "qux" }
hash.map(&:last) #=> ["bar", "qux"]

Why it works:

The & calls to_proc on the object, and passes it as a block to the method.

something {|i| i.foo }
something(&:foo)

Missing prerequisites. IBM has the solution below:

yum install gtk2.i686
yum install libXtst.i686

If you received the the missing libstdc++ message above, 
install the libstdc++ library: 
yum install compat-libstdc++

Option with a regexp if you want to discriminate between Mango and Mangosteen.

var reg = new Regex(@"\b(pineapple|mango)\b", 
                       RegexOptions.IgnoreCase | RegexOptions.Multiline);
   if (!reg.Match(compareString).Success)
      ...

You can find the last commit which deleted file as follows:

git rev-list -n 1 HEAD -- [file_path]

what i did was a quick fix by converting readlines to string but i do not recommencement it but it works and i dont know if there are limitations or not

`def getQuakeData():
    filename = input("Please enter the quake file: ")
    readfile = open(filename, "r")
    readlines = str(readfile.readlines())

    Type = readlines.split(",")
    x = Type[1]
    y = Type[2]
    for points in Type:
        print(x,y)
getQuakeData()`

The GetGenericArgument() method has to be set on the Base Type of your instance (whose class is a generic class myClass<T>). Otherwise, it returns a type[0]

Example:

Myclass<T> instance = new Myclass<T>();
Type[] listTypes = typeof(instance).BaseType.GetGenericArguments();

Happened to me when didn't install angular core:

Angular CLI: 9.0.0-rc.0
Node: 11.12.0
OS: darwin x64
Angular: undefined
...

So I run

npm i @angular/core

which gave me ng -v

Angular CLI: 9.0.0-rc.0
Node: 11.12.0
OS: darwin x64
Angular: 8.2.13
... core

Then I run

ng update @angular/cli --migrate-only --from=8.2.13

removed node_modules

npm install
cd <project name>
ng serve

And it worked!

}

java.time

You should use java.time classes with Java 8 and later. To use java.time, add:

import java.time.* ;

Below is an example, how you can format date.

DateTimeFormatter format = DateTimeFormatter.ofPattern("dd-MMM-yyyy");
String date = "15-Oct-2018";
LocalDate localDate = LocalDate.parse(date, formatter);

System.out.println(localDate); 
System.out.println(formatter.format(localDate));

All the other solutions here are OS dependent. An independent solution for any OS uses socket.io as follows.

package.json has two scripts:

"scripts": {
  "start": "node server.js",
  "stop": "node server.stop.js"
}

server.js - Your usual express stuff lives here

const express = require('express');
const app = express();
const server = http.createServer(app);
server.listen(80, () => {
  console.log('HTTP server listening on port 80');
});

// Now for the socket.io stuff - NOTE THIS IS A RESTFUL HTTP SERVER
// We are only using socket.io here to respond to the npmStop signal
// To support IPC (Inter Process Communication) AKA RPC (Remote P.C.)

const io = require('socket.io')(server);
io.on('connection', (socketServer) => {
  socketServer.on('npmStop', () => {
    process.exit(0);
  });
});

server.stop.js

const io = require('socket.io-client');
const socketClient = io.connect('http://localhost'); // Specify port if your express server is not using default port 80

socketClient.on('connect', () => {
  socketClient.emit('npmStop');
  setTimeout(() => {
    process.exit(0);
  }, 1000);
});

Test it out

npm start (to start your server as usual)

npm stop (this will now stop your running server)

The above code has not been tested (it is a cut down version of my code, my code does work) but hopefully it works as is. Either way, it provides the general direction to take if you want to use socket.io to stop your server.

If all those kill process commands don't work for you, my suggestion is to check if you were using any other packages to run your node process.

I had the similar issue, and it was due to I was running my node process using PM2(a NPM package). The kill [processID] command disables the process but keeps the port occupied. Hence I had to go into PM2 and dump all node process to free up the port again.

When i need to copy data from filtered table i use range.SpecialCells(xlCellTypeVisible).copy. Where the range is range of all data (without a filter).

Example:

Sub copy()
     'source worksheet
     dim ws as Worksheet
     set ws = Application.Worksheets("Data")' set you source worksheet here
     dim data_end_row_number as Integer
     data_end_row_number = ws.Range("B3").End(XlDown).Row.Number
    'enable filter
    ws.Range("B2:F2").AutoFilter Field:=2, Criteria1:="hockey", VisibleDropDown:=True
    ws.Range("B3:F" & data_end_row_number).SpecialCells(xlCellTypeVisible).Copy
    Application.Worksheets("Hoky").Range("B3").Paste
    'You have to add headers to Hoky worksheet
end sub

Call second ajax from 'complete'

Here is the example

   var dt='';
   $.ajax({
    type: "post",
    url: "ajax/example.php",
    data: 'page='+btn_page,
    success: function(data){
        dt=data;
        /*Do something*/
    },
    complete:function(){
        $.ajax({
           var a=dt; // This line shows error.
           type: "post",
           url: "example.php",
           data: 'page='+a,
           success: function(data){
              /*do some thing in second function*/
           },
       });
    }
});

just delete the app and try again, it happens to me when i try to launch over a device that has the same app but generated by an ipa file.

Try

sqlplus sys/<your password>@<your SID> as sysdba

In Kotlin:

private val id = 1
private val permissions = arrayOf(Manifest.permission.WRITE_EXTERNAL_STORAGE,Manifest.permission.ACCESS_FINE_LOCATION)
fun hasPermissions(): Boolean {
 for (perm in permissions) {
                if (ActivityCompat.checkSelfPermission(this, perm) != PackageManager.PERMISSION_GRANTED) {
                    return false
                }
            }

        return true
    }

    if(! hasPermissions()){
                   requestPermissions(this, permissions, id)
           }

Use the _ variable, as I learned when I asked this question, for example:

# A long way to do integer exponentiation
num = 2
power = 3
product = 1
for _ in xrange(power):
    product *= num
print product

My particular issue was caused because I was working with directories that involved symbolic links (shortcuts). Consequently, trying java -jar ../../myJar.jar didn't work because I wasn't where I thought I was.

Disregarding relative file paths fixed it right up.

import * as fs from 'fs';
import * as path from 'path';

fs.readFile(path.join(__dirname, "filename.txt"), (err, data) => {
    if (err) throw err;
    console.log(data);
})

EDIT:

consider the project structure:

../readfile/
+-- filename.txt
+-- src
    +-- index.js
    +-- index.ts

consider the index.ts:

import * as fs from 'fs';
import * as path from 'path';

function lookFilesInDirectory(path_directory) {
    fs.stat(path_directory, (err, stat) => {
        if (!err) {
            if (stat.isDirectory()) {
                console.log(path_directory)
                fs.readdirSync(path_directory).forEach(file => {
                    console.log(`\t${file}`);
                });
                console.log();
            }
        }
    });
}

let path_view = './';
lookFilesInDirectory(path_view);
lookFilesInDirectory(path.join(__dirname, path_view));

if you have in the readfile folder and run tsc src/index.ts && node src/index.js, the output will be:

./
        filename.txt
        src

/home/andrei/scripts/readfile/src/
        index.js
        index.ts

that is, it depends on where you run the node.

the __dirname is directory name of the current module.

The difference between do while (exit check) and while (entry check) is that while entering in do while it will not check but in while it will first check

The example is as such:

Program 1:

int a=10;
do{
System.out.println(a);
}
while(a<10);

//here the a is not less than 10 then also it will execute once as it will execute do while exiting it checks that a is not less than 10 so it will exit the loop

Program 2:

int b=0;
while(b<10)
{
System.out.println(b);
}
//here nothing will be printed as the value of b is not less than 10 and it will not let enter the loop and will exit

output Program 1:

10

output Program 2:

[nothing is printed]

note:

output of the program 1 and program 2 will be same if we assign a=0 and b=0 and also put a++; and b++; in the respective body of the program.

This is what I did

1. I made the Receiver class

public class BootReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        //whatever you want to do on boot
       Intent serviceIntent = new Intent(context, YourService.class);
       context.startService(serviceIntent);
    }
}

2.in the manifest

<manifest...>
    <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/>
    <application...>
        <receiver android:name=".BootReceiver" android:enabled="true" android:exported="false">
            <intent-filter>
                <action android:name="android.intent.action.BOOT_COMPLETED" />
            </intent-filter>
        </receiver>
    ...

3.and after ALL you NEED to "set" the receiver in your MainActivity, it may be inside the onCreate

...
 final ComponentName onBootReceiver = new ComponentName(getApplication().getPackageName(), BootReceiver.class.getName());
        if(getPackageManager().getComponentEnabledSetting(onBootReceiver) != PackageManager.COMPONENT_ENABLED_STATE_ENABLED)
        getPackageManager().setComponentEnabledSetting(onBootReceiver,PackageManager.COMPONENT_ENABLED_STATE_ENABLED,PackageManager.DONT_KILL_APP);
...

the final steap I have learned from ApiDemos

$search_string = 4;
$original_array = [1,2,1,3,2,4,4,4,4,4,10];
$step1 = implode(",", $original_array); // convert original_array to string
$step2 = explode($search_string, $step1); // break step1 string into a new array using the search string as delimiter
$result = count($step2)-1; // count the number of elements in the resulting array, minus the first empty element
print_r($result); // result is 5

Note that once you have imported the google-play-services_lib project into your IDE, you will also need to add google-play-services.jar to: Project=>Properties=>Java build path=>Libraries=>Add JARs

To avoid memory leaks you may use smart pointers whenever you can. There are basically 2 different types of smart pointers in C++

• Reference counted (e.g. boost::shared_ptr / std::tr1:shared_ptr)
• non reference counted (e.g. boost::scoped_ptr / std::auto_ptr)

The main difference is that reference counted smart pointers can be copied (and used in std:: containers) while scoped_ptr cannot. Non reference counted pointers have almost no overhead or no overhead at all. Reference counting always introduces some kind of overhead.

(I suggest to avoid auto_ptr, it has some serious flaws if used incorrectly)

I believe the correct way of doing it would be to use query builder expressions:

$now = new DateTimeImmutable();
$thirtyDaysAgo = $now->sub(new \DateInterval("P30D"));
$qb->select('e')
   ->from('Entity','e')
   ->add('where', $qb->expr()->between(
            'e.datefield',
            ':from',
            ':to'
        )
    )
   ->setParameters(array('from' => $thirtyDaysAgo, 'to' => $now));

Edit: The advantage this method has over any of the other answers here is that it's database software independent - you should let Doctrine handle the date type as it has an abstraction layer for dealing with this sort of thing.

If you do something like adding a string variable in the form 'Y-m-d' it will break when it goes to a database platform other than MySQL, for example.

the problem is that there is no built in method (or at least none of us could find one) to do this in vb. However, there is one to split a string on the spaces, so I just rebuild the string and added in spaces....

Private Function characterArray(ByVal my_string As String) As String()
  'create a temporary string to store a new string of the same characters with spaces
  Dim tempString As String = ""
  'cycle through the characters and rebuild my_string as a string with spaces 
  'and assign the result to tempString.  
  For Each c In my_string
     tempString &= c & " "
  Next
  'return return tempString as a character array.  
  Return tempString.Split()
End Function

I think PHP is a good solution. It's simple to set up, free and there is plenty of documentation on how to create a database management app. Ruby on Rails is faster to code but a bit more difficult to set up.

To get the fragments after orientation change you have to use the .getTag().

    getSupportFragmentManager().findFragmentByTag("android:switcher:" + viewPagerId + ":" + positionOfItemInViewPager)

For a bit more handling i wrote my own ArrayList for my PageAdapter to get the fragment by viewPagerId and the FragmentClass at any Position:

public class MyPageAdapter extends FragmentPagerAdapter implements Serializable {
private final String logTAG = MyPageAdapter.class.getName() + ".";

private ArrayList<MyPageBuilder> fragmentPages;

public MyPageAdapter(FragmentManager fm, ArrayList<MyPageBuilder> fragments) {
    super(fm);
    fragmentPages = fragments;
}

@Override
public Fragment getItem(int position) {
    return this.fragmentPages.get(position).getFragment();
}

@Override
public CharSequence getPageTitle(int position) {
    return this.fragmentPages.get(position).getPageTitle();
}

@Override
public int getCount() {
    return this.fragmentPages.size();
}


public int getItemPosition(Object object) {
    //benötigt, damit bei notifyDataSetChanged alle Fragemnts refrehsed werden

    Log.d(logTAG, object.getClass().getName());
    return POSITION_NONE;
}

public Fragment getFragment(int position) {
    return getItem(position);
}

public String getTag(int position, int viewPagerId) {
    //getSupportFragmentManager().findFragmentByTag("android:switcher:" + R.id.shares_detail_activity_viewpager + ":" + myViewPager.getCurrentItem())

    return "android:switcher:" + viewPagerId + ":" + position;
}

public MyPageBuilder getPageBuilder(String pageTitle, int icon, int selectedIcon, Fragment frag) {
    return new MyPageBuilder(pageTitle, icon, selectedIcon, frag);
}


public static class MyPageBuilder {

    private Fragment fragment;

    public Fragment getFragment() {
        return fragment;
    }

    public void setFragment(Fragment fragment) {
        this.fragment = fragment;
    }

    private String pageTitle;

    public String getPageTitle() {
        return pageTitle;
    }

    public void setPageTitle(String pageTitle) {
        this.pageTitle = pageTitle;
    }

    private int icon;

    public int getIconUnselected() {
        return icon;
    }

    public void setIconUnselected(int iconUnselected) {
        this.icon = iconUnselected;
    }

    private int iconSelected;

    public int getIconSelected() {
        return iconSelected;
    }

    public void setIconSelected(int iconSelected) {
        this.iconSelected = iconSelected;
    }

    public MyPageBuilder(String pageTitle, int icon, int selectedIcon, Fragment frag) {
        this.pageTitle = pageTitle;
        this.icon = icon;
        this.iconSelected = selectedIcon;
        this.fragment = frag;
    }
}

public static class MyPageArrayList extends ArrayList<MyPageBuilder> {
    private final String logTAG = MyPageArrayList.class.getName() + ".";

    public MyPageBuilder get(Class cls) {
        // Fragment über FragmentClass holen
        for (MyPageBuilder item : this) {
            if (item.fragment.getClass().getName().equalsIgnoreCase(cls.getName())) {
                return super.get(indexOf(item));
            }
        }
        return null;
    }

    public String getTag(int viewPagerId, Class cls) {
        // Tag des Fragment unabhängig vom State z.B. nach bei Orientation change
        for (MyPageBuilder item : this) {
            if (item.fragment.getClass().getName().equalsIgnoreCase(cls.getName())) {
                return "android:switcher:" + viewPagerId + ":" + indexOf(item);
            }
        }
        return null;
    }
}

So just create a MyPageArrayList with the fragments:

    myFragPages = new MyPageAdapter.MyPageArrayList();

    myFragPages.add(new MyPageAdapter.MyPageBuilder(
            getString(R.string.widget_config_data_frag),
            R.drawable.ic_sd_storage_24dp,
            R.drawable.ic_sd_storage_selected_24dp,
            new WidgetDataFrag()));

    myFragPages.add(new MyPageAdapter.MyPageBuilder(
            getString(R.string.widget_config_color_frag),
            R.drawable.ic_color_24dp,
            R.drawable.ic_color_selected_24dp,
            new WidgetColorFrag()));

    myFragPages.add(new MyPageAdapter.MyPageBuilder(
            getString(R.string.widget_config_textsize_frag),
            R.drawable.ic_settings_widget_24dp,
            R.drawable.ic_settings_selected_24dp,
            new WidgetTextSizeFrag()));

and add them to the viewPager:

    mAdapter = new MyPageAdapter(getSupportFragmentManager(), myFragPages);
    myViewPager.setAdapter(mAdapter);

after this you can get after orientation change the correct fragment by using its class:

        WidgetDataFrag dataFragment = (WidgetDataFrag) getSupportFragmentManager()
            .findFragmentByTag(myFragPages.getTag(myViewPager.getId(), WidgetDataFrag.class));

Java does appear to be well behind the eight-ball compared to C#. This utility method shows the way to do in Java SE 6 using the Calendar.add method (presumably the only easy way).

public class DateUtil
{
    public static Date addDays(Date date, int days)
    {
        Calendar cal = Calendar.getInstance();
        cal.setTime(date);
        cal.add(Calendar.DATE, days); //minus number would decrement the days
        return cal.getTime();
    }
}

To add one day, per the question asked, call it as follows:

String sourceDate = "2012-02-29";
SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd");
Date myDate = format.parse(sourceDate);
myDate = DateUtil.addDays(myDate, 1);

Most layout managers work best with a component's preferredSize, and most GUI's are best off allowing the components they contain to set their own preferredSizes based on their content or properties. To use these layout managers to their best advantage, do call pack() on your top level containers such as your JFrames before making them visible as this will tell these managers to do their actions -- to layout their components.

Often when I've needed to play a more direct role in setting the size of one of my components, I'll override getPreferredSize and have it return a Dimension that is larger than the super.preferredSize (or if not then it returns the super's value).

For example, here's a small drag-a-rectangle app that I created for another question on this site:

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

public class MoveRect extends JPanel {
   private static final int RECT_W = 90;
   private static final int RECT_H = 70;
   private static final int PREF_W = 600;
   private static final int PREF_H = 300;
   private static final Color DRAW_RECT_COLOR = Color.black;
   private static final Color DRAG_RECT_COLOR = new Color(180, 200, 255);
   private Rectangle rect = new Rectangle(25, 25, RECT_W, RECT_H);
   private boolean dragging = false;
   private int deltaX = 0;
   private int deltaY = 0;

   public MoveRect() {
      MyMouseAdapter myMouseAdapter = new MyMouseAdapter();
      addMouseListener(myMouseAdapter);
      addMouseMotionListener(myMouseAdapter);
   }

   @Override
   protected void paintComponent(Graphics g) {
      super.paintComponent(g);
      if (rect != null) {
         Color c = dragging ? DRAG_RECT_COLOR : DRAW_RECT_COLOR;
         g.setColor(c);
         Graphics2D g2 = (Graphics2D) g;
         g2.draw(rect);
      }
   }

   @Override
   public Dimension getPreferredSize() {
      return new Dimension(PREF_W, PREF_H);
   }

   private class MyMouseAdapter extends MouseAdapter {

      @Override
      public void mousePressed(MouseEvent e) {
         Point mousePoint = e.getPoint();
         if (rect.contains(mousePoint)) {
            dragging = true;
            deltaX = rect.x - mousePoint.x;
            deltaY = rect.y - mousePoint.y;
         }
      }

      @Override
      public void mouseReleased(MouseEvent e) {
         dragging = false;
         repaint();
      }

      @Override
      public void mouseDragged(MouseEvent e) {
         Point p2 = e.getPoint();
         if (dragging) {
            int x = p2.x + deltaX;
            int y = p2.y + deltaY;
            rect = new Rectangle(x, y, RECT_W, RECT_H);
            MoveRect.this.repaint();
         }
      }
   }

   private static void createAndShowGui() {
      MoveRect mainPanel = new MoveRect();

      JFrame frame = new JFrame("MoveRect");
      frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
      frame.getContentPane().add(mainPanel);
      frame.pack();
      frame.setLocationByPlatform(true);
      frame.setVisible(true);
   }

   public static void main(String[] args) {
      SwingUtilities.invokeLater(new Runnable() {
         public void run() {
            createAndShowGui();
         }
      });
   }
}

Note that my main class is a JPanel, and that I override JPanel's getPreferredSize:

public class MoveRect extends JPanel {
   //.... deleted constants

   private static final int PREF_W = 600;
   private static final int PREF_H = 300;

   //.... deleted fields and constants

   //... deleted methods and constructors

   @Override
   public Dimension getPreferredSize() {
      return new Dimension(PREF_W, PREF_H);
   }

Also note that when I display my GUI, I place it into a JFrame, call pack(); on the JFrame, set its position, and then call setVisible(true); on my JFrame:

   private static void createAndShowGui() {
      MoveRect mainPanel = new MoveRect();

      JFrame frame = new JFrame("MoveRect");
      frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
      frame.getContentPane().add(mainPanel);
      frame.pack();
      frame.setLocationByPlatform(true);
      frame.setVisible(true);
   }

   public static void main(String[] args) {
      SwingUtilities.invokeLater(new Runnable() {
         public void run() {
            createAndShowGui();
         }
      });
   }
}

I used conda install python-graphviz then conda install pydot and then conda install pydot plus and then it worked.

So:

conda install python-graphviz
conda install pydot
conda install pydotplus

$_SERVER['HTTP_REFERER'];

But if you run a file (that contains the above code) by directly hitting the URL in the browser then you get the following error.

Notice: Undefined index: HTTP_REFERER

<select id="selectId">
    <option value="A">A</option>
    <option value="B">B</option>
    <option value="C">C</option>
</select>


$('#selectId').on('change', function () {
     var selectVal = $("#selectId option:selected").val();
});

First create a select option. After that using jquery you can get current selected value when user change select option value.

You are calling:

JSON.parse(scatterSeries)

But when you defined scatterSeries, you said:

var scatterSeries = []; 

When you try to parse it as JSON it is converted to a string (""), which is empty, so you reach the end of the string before having any of the possible content of a JSON text.

scatterSeries is not JSON. Do not try to parse it as JSON.

data is not JSON either (getJSON will parse it as JSON automatically).

ch is JSON … but shouldn't be. You should just create a plain object in the first place:

var ch = {
    "name": "graphe1",
    "items": data.results[1]
};

scatterSeries.push(ch);

In short, for what you are doing, you shouldn't have JSON.parse anywhere in your code. The only place it should be is in the jQuery library itself.

What about hex()?

hex(255)  # 0xff

If you really want to have \ in front you can do:

print '\\' + hex(255)[1:]

The right solution is to Specialize std::less for your class/Struct.

• Basically maps in cpp are implemented as Binary Search Trees.

1. BSTs compare elements of nodes to determine the organization of the tree.
2. Nodes who's element compares less than that of the parent node are placed on the left of the parent and nodes whose elements compare greater than the parent nodes element are placed on the right. i.e.

For each node, node.left.key < node.key < node.right.key

Every node in the BST contains Elements and in case of maps its KEY and a value, And keys are supposed to be ordered. More About Map implementation : The Map data Type.

In case of cpp maps , keys are the elements of the nodes and values does not take part in the organization of the tree its just a supplementary data .

So It means keys should be compatible with std::less or operator< so that they can be organized. Please check map parameters.

Else if you are using user defined data type as keys then need to give meaning full comparison semantics for that data type.

Solution : Specialize std::less:

The third parameter in map template is optional and it is std::less which will delegate to operator< ,

So create a new std::less for your user defined data type. Now this new std::less will be picked by std::map by default.

namespace std
{
    template<> struct  less<MyClass>
    {
        bool operator() (const MyClass& lhs, const MyClass& rhs) const
        {
            return lhs.anyMemen < rhs.age;
        }
    };

}

Note: You need to create specialized std::less for every user defined data type(if you want to use that data type as key for cpp maps).

Bad Solution: Overloading operator< for your user defined data type. This solution will also work but its very bad as operator < will be overloaded universally for your data type/class. which is undesirable in client scenarios.

Please check answer Pavel Minaev's answer

You're storing the .Text properties of the textboxes directly into the database, this doesn't work. The .Text properties are Strings (i.e. simple text) and not typed as DateTime instances. Do the conversion first, then it will work.

Do this for each date parameter:

Dim bookIssueDate As DateTime = DateTime.ParseExact( txtBookDateIssue.Text, "dd/MM/yyyy", CultureInfo.InvariantCulture ) cmd.Parameters.Add( New OleDbParameter("@Date_Issue", bookIssueDate ) ) 

Note that this code will crash/fail if a user enters an invalid date, e.g. "64/48/9999", I suggest using DateTime.TryParse or DateTime.TryParseExact, but implementing that is an exercise for the reader.

What fixed the "Could not find schema information for the element ..." for me was

• Opening my app.config.
• Right-clicking in the editor window and selecting Properties.
• In the properties box, there is a row called Schemas, I clicked that row and selected the browse ... box that appears in the row.
• I simply checked the use box for all the rows that had my project somewhere in them, and also for the current version of .Net I was using. For instance: DotNetConfig30.xsd.

After that everything went to working fine.

How those schema rows with my project got unchecked I'm not sure, but when I made sure they were checked, I was back in business.

There are many ways to do this. My favorite way is:

1. Add a mod_user field to your source table (the one you want to log).

2. Create a log table that contains the fields you want to log, plus a log_datetime and seq_num field. seq_num is the primary key.

3. Build a trigger on the source table that inserts the current record into the log table whenever any monitored field is changed.

Now you've got a record of every change and who made it.

If you want to dump the entire db as csv

The only really accurate way of distinguishing real, valid email addresses from invalid ones is to send mail to it. What counts as an email is surprisingly convoluted ("John Doe" <[email protected]>" actually is a valid email address), and you most likely want the email address to actually send mail to it later. After it passes some basic sanity checks (such as in Thomas's answer, has an @ and at least one . after the @), you should probably just send an email verification letter to the address, and wait for the user to follow a link embedded in the message to confirm that the email was valid.

You can use SET in cmd

To show the current variable, just SET is enough

To show certain variable such as 'PATH', use SET PATH.

For help, type set /?.

Can em.flush() cause any harm when using it within a transaction?

Yes, it may hold locks in the database for a longer duration than necessary.

Generally, When using JPA you delegates the transaction management to the container (a.k.a CMT - using @Transactional annotation on business methods) which means that a transaction is automatically started when entering the method and commited / rolled back at the end. If you let the EntityManager handle the database synchronization, sql statements execution will be only triggered just before the commit, leading to short lived locks in database. Otherwise your manually flushed write operations may retain locks between the manual flush and the automatic commit which can be long according to remaining method execution time.

Notes that some operation automatically triggers a flush : executing a native query against the same session (EM state must be flushed to be reachable by the SQL query), inserting entities using native generated id (generated by the database, so the insert statement must be triggered thus the EM is able to retrieve the generated id and properly manage relationships)

Encryption has not only cpu, but also some network overhead.

I think there is another reason for wanting to set java.library.path. Subversion comes with many libraries and Eclipse won't see these unless java.library.path can be appended. For example I'm on OS-X, so the libraries are under \opt\subversion\lib. There are a lot of them and I'd like to keep them where they are (not copy them into a standard lib directory).

Project settings won't fix this.

var currentDate = moment('2015-10-30');
var futureMonth = moment(currentDate).add(1, 'M');
var futureMonthEnd = moment(futureMonth).endOf('month');

if(currentDate.date() != futureMonth.date() && futureMonth.isSame(futureMonthEnd.format('YYYY-MM-DD'))) {
    futureMonth = futureMonth.add(1, 'd');
}

console.log(currentDate);
console.log(futureMonth);

DEMO

EDIT

moment.addRealMonth = function addRealMonth(d) {
  var fm = moment(d).add(1, 'M');
  var fmEnd = moment(fm).endOf('month');
  return d.date() != fm.date() && fm.isSame(fmEnd.format('YYYY-MM-DD')) ? fm.add(1, 'd') : fm;  
}

var nextMonth = moment.addRealMonth(moment());

If you assign parent type to a subclass it means that you agree with to use the common features of the parent class.

It gives you the freedom to abstract from different subclass implementations. As a result limits you with the parent features.

However, this type of assignment is called upcasting.

Parent parent = new Child();  

The opposite is downcasting.

Child child = (Child)parent;

So, if you create instance of Child and downcast it to Parent you can use that type attribute name. If you create instance of Parent you can do the same as with previous case but you can't use salary because there's not such attribute in the Parent. Return to the previous case that can use salary but only if downcasting to Child.

There's more detail explanation

This should solve it:

1. Open the Visual Studio Installer.
   
2. Click on the Modify Button.
   
3. Choose the Language Pack tab on top left.
   
4. Check the language you need and click on the Modify Button at bottom right.

"start" is a name of a script, in npm you run scripts like this npm run scriptName, npm start is also a short for npm run start

As for "react-scripts" this is a script related specifically to create-react-app

It's not in standard C, so the behavior is undefined.

Some implementation uses it to clear stdin buffer.

From C11 7.21.5.2 The fflush function, fflush works only with output/update stream, not input stream.

If stream points to an output stream or an update stream in which the most recent operation was not input, the fflush function causes any unwritten data for that stream to be delivered to the host environment to be written to the file; otherwise, the behavior is undefined.

format(99999999,scientific = F)

gives

99999999

The main difference is ::

npm install is a npm cli-command which does the predefined thing i.e, as written by Churro, to install dependencies specified inside package.json

npm run command-name or npm run-script command-name ( ex. npm run build ) is also a cli-command predefined to run your custom scripts with the name specified in place of "command-name". So, in this case npm run build is a custom script command with the name "build" and will do anything specified inside it (for instance echo 'hello world' given in below example package.json).

Ponits to note::

1. One more thing, npm build and npm run build are two different things, npm run build will do custom work written inside package.json and npm build is a pre-defined script (not available to use directly)

2. You cannot specify some thing inside custom build script (npm run build) script and expect npm build to do the same. Try following thing to verify in your package.json:

   { "name": "demo", "version": "1.0.0", "description": "", "main": "index.js", "scripts": { "build":"echo 'hello build'" }, "keywords": [], "author": "", "license": "ISC", "devDependencies": {}, "dependencies": {} }

and run npm run build and npm build one by one and you will see the difference. For more about commands kindly follow npm documentation.

To reset a specific file to the last-committed state (to discard uncommitted changes in a specific file):

git checkout thefiletoreset.txt

This is mentioned in the git status output:

(use "git checkout -- <file>..." to discard changes in working directory)

To reset the entire repository to the last committed state:

git reset --hard

To remove untracked files, I usually just delete all files in the working copy (but not the .git/ folder!), then do git reset --hard which leaves it with only committed files.

A better way is to use git clean (warning: using the -x flag as below will cause Git to delete ignored files):

git clean -d -x -f

will remove untracked files, including directories (-d) and files ignored by git (-x). Replace the -f argument with -n to perform a dry-run or -i for interactive mode, and it will tell you what will be removed.

Relevant links:

• git-reset man page
• git-clean man page
• git ready "cleaning up untracked files" (as Marko posted)
• Stack Overflow question "How to remove local (untracked) files from the current Git working tree")

You can just use numpy arrays. Look at the numpy for matlab users page for a detailed overview of the pros and cons of arrays w.r.t. matrices.

As I mentioned in the comment, having to use the dot() function or method for mutiplication of vectors is the biggest pitfall. But then again, numpy arrays are consistent. All operations are element-wise. So adding or subtracting arrays and multiplication with a scalar all work as expected of vectors.

Edit2: Starting with Python 3.5 and numpy 1.10 you can use the @ infix-operator for matrix multiplication, thanks to pep 465.

Edit: Regarding your comment:

1. Yes. The whole of numpy is based on arrays.

2. Yes. linalg.norm(v) is a good way to get the length of a vector. But what you get depends on the possible second argument to norm! Read the docs.

3. To normalize a vector, just divide it by the length you calculated in (2). Division of arrays by a scalar is also element-wise.

   An example in ipython:

   In [1]: import math
   
   In [2]: import numpy as np
   
   In [3]: a = np.array([4,2,7])
   
   In [4]: np.linalg.norm(a)
   Out[4]: 8.3066238629180749
   
   In [5]: math.sqrt(sum([n**2 for n in a]))
   Out[5]: 8.306623862918075
   
   In [6]: b = a/np.linalg.norm(a)
   
   In [7]: np.linalg.norm(b)
   Out[7]: 1.0
   

   Note that In [5] is an alternative way to calculate the length. In [6] shows normalizing the vector.

My issue was, i am unable to create a view with my "scott" user in oracle 11g edition. So here is my solution for this

Error in my case

SQL>create view v1 as select * from books where id=10;

insufficient privileges.

Solution

1)open your cmd and change your directory to where you install your oracle database. in my case i was downloaded in E drive so my location is E:\app\B_Amar\product\11.2.0\dbhome_1\BIN> after reaching in the position you have to type sqlplus sys as sysdba

E:\app\B_Amar\product\11.2.0\dbhome_1\BIN>sqlplus sys as sysdba

2) Enter password: here you have to type that password that you give at the time of installation of oracle software.

3) Here in this step if you want create a new user then you can create otherwise give all the privileges to existing user.

for creating new user

SQL> create user abc identified by xyz;

here abc is user and xyz is password.

giving all the privileges to abc user

SQL> grant all privileges to abc;

 grant succeeded. 

if you are seen this message then all the privileges are giving to the abc user.

4) Now exit from cmd, go to your SQL PLUS and connect to the user i.e enter your username & password.Now you can happily create view.

In My case

in cmd E:\app\B_Amar\product\11.2.0\dbhome_1\BIN>sqlplus sys as sysdba

SQL> grant all privileges to SCOTT;

grant succeeded.

Now I can create views.

on your onCreate method add setHasOptionMenu()

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setHasOptionsMenu(true);
}

Then override your onCreateOptionsMenu

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
    menu.add("Menu item")
            .setIcon(android.R.drawable.ic_delete)
            .setShowAsAction(MenuItem.SHOW_AS_ACTION_IF_ROOM);
}

select method > right click > References > Workspace/Project (your preferred context ) 

or

(Ctrl+Shift+G) 

This will show you a Search view containing the hierarchy of class and method which using this method.

in code there should be coma"," not colon ":"

the code must be $(this).css({'background-color' , '#FFFFEE'});

i hope it helps.

In my experience, rules engines work best when the following are true:

1. Well-defined doctrine for your problem domain
2. High quality (preferably automated) data to help drive most of your inputs
3. Access to subject matter experts
4. Software developers with experience creating expert systems

If any of these four traits are missing, you still might find a rules engine works for you, but every time I've tried it with even 1 missing, I've run into trouble.

GUIDs may seem to be a natural choice for your primary key - and if you really must, you could probably argue to use it for the PRIMARY KEY of the table. What I'd strongly recommend not to do is use the GUID column as the clustering key, which SQL Server does by default, unless you specifically tell it not to.

You really need to keep two issues apart:

1. the primary key is a logical construct - one of the candidate keys that uniquely and reliably identifies every row in your table. This can be anything, really - an INT, a GUID, a string - pick what makes most sense for your scenario.

2. the clustering key (the column or columns that define the "clustered index" on the table) - this is a physical storage-related thing, and here, a small, stable, ever-increasing data type is your best pick - INT or BIGINT as your default option.

By default, the primary key on a SQL Server table is also used as the clustering key - but that doesn't need to be that way! I've personally seen massive performance gains when breaking up the previous GUID-based Primary / Clustered Key into two separate key - the primary (logical) key on the GUID, and the clustering (ordering) key on a separate INT IDENTITY(1,1) column.

As Kimberly Tripp - the Queen of Indexing - and others have stated a great many times - a GUID as the clustering key isn't optimal, since due to its randomness, it will lead to massive page and index fragmentation and to generally bad performance.

Yes, I know - there's newsequentialid() in SQL Server 2005 and up - but even that is not truly and fully sequential and thus also suffers from the same problems as the GUID - just a bit less prominently so.

Then there's another issue to consider: the clustering key on a table will be added to each and every entry on each and every non-clustered index on your table as well - thus you really want to make sure it's as small as possible. Typically, an INT with 2+ billion rows should be sufficient for the vast majority of tables - and compared to a GUID as the clustering key, you can save yourself hundreds of megabytes of storage on disk and in server memory.

Quick calculation - using INT vs. GUID as Primary and Clustering Key:

• Base Table with 1'000'000 rows (3.8 MB vs. 15.26 MB)
• 6 nonclustered indexes (22.89 MB vs. 91.55 MB)

TOTAL: 25 MB vs. 106 MB - and that's just on a single table!

Some more food for thought - excellent stuff by Kimberly Tripp - read it, read it again, digest it! It's the SQL Server indexing gospel, really.

• GUIDs as PRIMARY KEY and/or clustered key
• The clustered index debate continues
• Ever-increasing clustering key - the Clustered Index Debate..........again!
• Disk space is cheap - that's not the point!

PS: of course, if you're dealing with just a few hundred or a few thousand rows - most of these arguments won't really have much of an impact on you. However: if you get into the tens or hundreds of thousands of rows, or you start counting in millions - then those points become very crucial and very important to understand.

Update: if you want to have your PKGUID column as your primary key (but not your clustering key), and another column MYINT (INT IDENTITY) as your clustering key - use this:

CREATE TABLE dbo.MyTable
(PKGUID UNIQUEIDENTIFIER NOT NULL,
 MyINT INT IDENTITY(1,1) NOT NULL,
 .... add more columns as needed ...... )

ALTER TABLE dbo.MyTable
ADD CONSTRAINT PK_MyTable
PRIMARY KEY NONCLUSTERED (PKGUID)

CREATE UNIQUE CLUSTERED INDEX CIX_MyTable ON dbo.MyTable(MyINT)

Basically: you just have to explicitly tell the PRIMARY KEY constraint that it's NONCLUSTERED (otherwise it's created as your clustered index, by default) - and then you create a second index that's defined as CLUSTERED

This will work - and it's a valid option if you have an existing system that needs to be "re-engineered" for performance. For a new system, if you start from scratch, and you're not in a replication scenario, then I'd always pick ID INT IDENTITY(1,1) as my clustered primary key - much more efficient than anything else!

If there are are no duplicate elements or you don't care about them, then you can use the Set class:

a1 = Set.new [5, 1, 6, 14, 2, 8]
a2 = Set.new [2, 6, 15]
a1.subset?(a2)
=> false

Behind the scenes this uses

all? { |o| set.include?(o) }

I would suggest:

DECLARE @sqlStatement nvarchar(MAX),
        @tableName nvarchar(50) = 'TripEvent',
        @columnName nvarchar(50) = 'CreatedDate';

SELECT                  @sqlStatement = 'ALTER TABLE ' + @tableName + ' DROP CONSTRAINT ' + dc.name + ';'
        FROM            sys.default_constraints AS dc
            LEFT JOIN   sys.columns AS sc
                ON      (dc.parent_column_id = sc.column_id)
        WHERE           dc.parent_object_id = OBJECT_ID(@tableName)
        AND         type_desc = 'DEFAULT_CONSTRAINT'
        AND         sc.name = @columnName
PRINT'   ['+@tableName+']:'+@@SERVERNAME+'.'+DB_NAME()+'@'+CONVERT(VarChar, GETDATE(), 127)+';  '+@sqlStatement;
IF(LEN(@sqlStatement)>0)EXEC sp_executesql @sqlStatement

Your product class needs a parameterless constructor. You can make it private, but Jackson needs the constructor.

As a side note: You should use Pascal casing for your class names. That is Product, and not product.

For those without LINQ:

RadioButton GetCheckedRadio(Control container)
{
    foreach (var control in container.Controls)
    {
        RadioButton radio = control as RadioButton;

        if (radio != null && radio.Checked)
        {
            return radio;
        }
    }

    return null;
}

Google's R style guide simplifies the issue by prohibiting the "=" for assignment. Not a bad choice.

https://google.github.io/styleguide/Rguide.xml

The R manual goes into nice detail on all 5 assignment operators.

You are correct that blanks "" or a string "#N/A" are indeed interpreted as having values in excel. You need to use a function NA().

    document.getElementById("something").innerHTML = "<img src=\"something\" onmouseover=\"change('ex1')\" />";

OR

    document.getElementById("something").innerHTML = '<img src="something" onmouseover="change(\'ex1\')" />';

It should be working...

Use the "form" attribute, if you want to save your markup:

<form method="GET" id="my_form"></form>

<table>
    <tr>
        <td>
            <input type="text" name="company" form="my_form" />
            <button type="button" form="my_form">ok</button>
        </td>
    </tr>
</table>

(*Form fields outside of the < form > tag)

Let's take a look at the stock hashCode() method:

public int hashCode() {
    int h = hash;
    if (h == 0 && count > 0) {
        for (int i = 0; i < count; i++) {
            h = 31 * h + charAt(i);
        }
        hash = h;
    }
    return h;
}

The block of code above comes from the java.lang.String class. As you can see it is a 32 bit hash code which fair enough if you are using it on a small scale of data. If you are looking for hash code with more than 32 bit, you might wanna checkout this link: http://www.javamex.com/tutorials/collections/strong_hash_code_implementation.shtml

You can also use breakpoints. Assuming the value you want is defined within the scope of your breakpoint you have 3 options:

print it in console doing:

po some_paramter

Bare in mind in objective-c for properties you can't use self.

po _someProperty
po self.someProperty // would not work

po stands for print object.

I highly recommend seeing Debugging with Xcode from Apple

Or just hover over within your code. Like the image below.

From Haskell:

Haskell is a standardized, general-purpose purely functional programming language, with non-strict semantics and strong static typing. It is named after logician Haskell Curry.

Basically Haskell can be used to create pretty much anything you would normally create using other general-purpose languages (e.g. C#, Java, C, C++, etc.).

using (SqlConnection connection =  new SqlConnection("Data Source=localhost;Initial Catalog=LoginScreen;Integrated Security=True"))
{
    SqlCommand command =
    new SqlCommand("select * from Pending_Tasks WHERE CustomerId=...", connection);
    connection.Open();

    SqlDataReader read= command.ExecuteReader();

    while (read.Read())
    {
        CustID.Text = (read["Customer_ID"].ToString());
        CustName.Text = (read["Customer_Name"].ToString());
        Add1.Text = (read["Address_1"].ToString());
        Add2.Text = (read["Address_2"].ToString());

        MobNumber.Text = (read["Mobile"].ToString());
        FaultRep.Text = (read["Fault_Report"].ToString());
    }
    read.Close();
}

Make sure you have data in the query : select * from Pending_Tasks and you are using "using System.Data.SqlClient;"

I had issues installing Express on Ubuntu:

If for some reason NPM command is missing, test npm command with npm help. If not there, follow these steps - http://arnolog.net/post/8424207595/installing-node-js-npm-express-mongoose-on-ubuntu

If just the Express command is not working, try:

sudo npm install -g express

This made everything work as I'm used to with Windows7 and OSX.

Hope this helps!

To understand both the methods let's take an example:

int i =0;
MessageBox.Show(i.ToString());
MessageBox.Show(Convert.ToString(i)); 

Here both the methods are used to convert the string but the basic difference between them is: Convert function handles NULL, while i.ToString() does not it will throw a NULL reference exception error. So as good coding practice using convert is always safe.

Let's see another example:

string s;
object o = null;
s = o.ToString(); 
//returns a null reference exception for s. 

string s;
object o = null;
s = Convert.ToString(o); 
//returns an empty string for s and does not throw an exception.

With Entity Framework 6.1, you can now do this:

[Index("IX_FirstAndSecond", 1, IsUnique = true)]
public int FirstColumn { get; set; }

[Index("IX_FirstAndSecond", 2, IsUnique = true)]
public int SecondColumn { get; set; }

The second parameter in the attribute is where you can specify the order of the columns in the index.

Just write in your Custom ArrayAdaper this code:

private List<Cart_items> customListviewList ;

refreshEvents(carts);

public void refreshEvents(List<Cart_items> events)
{
    this.customListviewList.clear();
    this.customListviewList.addAll(events);
    notifyDataSetChanged();
}

you are calling the push() on an array element (int), where push() should be called on the array, also handling/filling the array this way makes no sense you can do it like this

for (var i = 0; i < rows - 1; i++)
{
  for (var j = c; j < cols; j++)
  {
    myArray[i].push(0);
  }
}


for (var i = r; i < rows - 1; i++)
{

  for (var j = 0; j < cols; j++)
  {
      col.push(0);
  }
}

you can also combine the two loops using an if condition, if row < r, else if row >= r

I may have not got your answer correct, but you can try this:

public void MusicController(View view) throws IOException{
    switch (view.getId()){
        case R.id.play: mplayer.start();break;
        case R.id.pause: mplayer.pause(); break;
        case R.id.stop:
            if(mplayer.isPlaying()) {
                mplayer.stop();
                mplayer.prepare(); 
            }
            break;

    }// where mplayer is defined in  onCreate method}

as there is just one thread handling all, so stop() makes it die so we have to again prepare it If your intent is to start it again when your press start button(it throws IO Exception) Or for better understanding of MediaPlayer you can refer to Android Media Player

A simple array assignment works... Note that the first element of a bash array can be addressed by just the name without the [0] index, ie, $md5 contains only the 32 chars of the md5sum.

md5=($(md5sum file))
echo $md5
# 53c8fdfcbb60cf8e1a1ee90601cc8fe2

As we see (from the answers), there is no standard way for this; and different markdown processors would differ in their markdown extension that offer this kind of possibilities.

With pandoc, you can get what you asked for like this:

Take me to [pookie](#pookie)

...

[this is pookie]{#pookie}

This gives (with pandoc-2.9.2.1):

<p>Take me to <a href="#pookie">pookie</a></p>
<p>…</p>
<p><span id="pookie">this is pookie</span></p>

One can also make an empty span with an anchor id:

Take me to [pookie](#pookie)

...

this is pookie []{#pookie}

which would produce:

<p>Take me to <a href="#pookie">pookie</a></p>
<p>…</p>
<p>this is pookie <span id="pookie"></span></p>

Apart from this, for pandoc and for most common markdown generators, you have a simple self generated anchor in each header. (See that and other answers here for convenient ways to (auto)generate and refernce such anchors.)

You can USE PyPDF2 package

#install pyDF2
pip install PyPDF2

# importing all the required modules
import PyPDF2

# creating an object 
file = open('example.pdf', 'rb')

# creating a pdf reader object
fileReader = PyPDF2.PdfFileReader(file)

# print the number of pages in pdf file
print(fileReader.numPages)

Follow this Documentation http://pythonhosted.org/PyPDF2/

You can use the diff language tag to generate some colored text:

```diff

! text in orange
# text in gray
@@ text in purple (and bold)@@

However, it adds it as a new line starting with either - + ! # or starts and ends with @@

This issue was raised in github markup #369, but they haven't made any change in decision since then (2014).

1. Go to Settings -> Debugger -> Common -> GDB/CDB Debugger -> Default
2. Click on executable path to find the address to gdb32.exe
3. Locate where your codeblock is installed
4. Follow the given path:

CodeBlock -> MinGW -> bin -> gdb32.exe (locate it and double click on it)

5. Press OK

An Ad-hoc query is one created to provide a specific recordset from any or multiple merged tables available on the DB server. These queries usually serve a single-use purpose, and may not be necessary to incorporate into any stored procedure to run again in the future.

Ad-hoc scenario: You receive a request for a specific subset of data with a unique set of variables. If there is no pre-written query that can provide the necessary results, you must write an Ad-hoc query to generate the recordset results.

Beyond a single use Ad-hoc query are stored procedures; i.e. queries which are stored within the DB interface tool. These stored procedures can then be executed in sequence within a module or macro to accomplish a predefined task either on demand, on a schedule, or triggered by another event.

Stored Procedure scenario: Every month you need to generate a report from the same set of tables and with the same variables (these variables may be specific predefined values, computed values such as “end of current month”, or a user’s input values). You would created the procedure as an ad-hoc query the first time. After testing the results to ensure accuracy, you may chose to deploy this query. You would then store the query or series of queries in a module or macro to run again as needed.

You just need sed to do this:

kubectl get pods --no-headers=true --all-namespaces |sed -r 's/(\S+)\s+(\S+).*/kubectl --namespace \1 delete pod \2/e'

Explains:

1. use command kubectl get pods --all-namespaces to get the list of all pods in all namespaces.
2. use --no-headers=true option to hide the headers.
3. use s command of sed to fetch the first two words, which represent namespace and pod's name respectively, then assemble the delete command using them.
4. the final delete command is just like: kubectl --namespace kube-system delete pod heapster-eq3yw.
5. use the e modifier of s command to execute the command assembled above, which will do the actual delete works.

To avoid delete pods in kube-system namespace, just need to add grep -v kube-system to exclude kube-system namespace before the sed command.

You can also do this in ASP.NET Core 2 by defining the connection string in your appSettings.json file. Then in your Startup.cs you specify which connection string to use.

appSettings.json

{
    "connectionStrings": {
        "YourDBConnectionString": "Server=(localdb)\\mssqllocaldb;Database=YourDB;Trusted_Connection=True"
    }
}

Startup.cs

public static IConfiguration Configuration { get; private set;}

public Startup(IConfiguration configuration)
{
    Configuration = configuration;
}
var connectionString = Configuration["connectionStrings:YourDBConnectionString"];
services.AddDbContext<YourDbContext>(x => x.UseSqlServer(connectionString));

Yes, to some degree as detailed here.
The approach I've used (pre-2008) is to do the conversion in the .NET business logic before inserting into the DB.

This is, IMHO, the most generic and robust solution (if your actions are user-triggered, eg 'user clicks on a button'):

• the first time a handler is called check WHO triggered it:
  • if a user tiggered it - do your stuff, and then trigger it again (if you want) - programmatically
  • otherwise - do nothing (= "continue default")

As an example, note this elegant solution to adding "Are you sure?" popup to any button just by decorating a button with an attribute. We will conditionally continue default behavior if the user doesn't opt out.

1. Let's add to every button that we want an "are you sure" popup a warning text:

<button class="btn btn-success-outline float-right" type="submit"  ays_text="You will lose any unsaved changes... Do you want to continue?"                >Do something dangerous</button>

2. Attach handlers to ALL such buttons:

$('button[ays_text]').click(function (e, from) {
    if (from == null) {  // user clicked it!
        var btn = $(this);
        e.preventDefault();
        if (confirm() == true) {
            btn.trigger('click', ['your-app-name-here-or-anything-that-is-not-null']);
        }
    }
    // otherwise - do nothing, ie continue default
});

That's it.

The best option would be to put any element you want to be centered in a div like this:

        <div class="center">
            <img src="images/logo.png" />
        </div>

and css or inline style:

.center {  
      text-align:center  
 }

In my Windows 7 box I found netbeans.conf in <Drive>:\<Program Files folder>\<NetBeans installation folder>\etc . Thanks all.

Most of the time,bootstrap project uses jQuery, so you can use jQuery.

Just get the width and height of parent with JQuery.offsetHeight() and JQuery.offsetWidth(), and set them to the child element with JQuery.width() and JQuery.height().

If you want to make it responsive, repeat the above steps in the $(window).resize(func), as well.

With GNU Make, you can use shell and eval to store, run, and assign output from arbitrary command line invocations. The difference between the example below and those which use := is the := assignment happens once (when it is encountered) and for all. Recursively expanded variables set with = are a bit more "lazy"; references to other variables remain until the variable itself is referenced, and the subsequent recursive expansion takes place each time the variable is referenced, which is desirable for making "consistent, callable, snippets". See the manual on setting variables for more info.

# Generate a random number.
# This is not run initially.
GENERATE_ID = $(shell od -vAn -N2 -tu2 < /dev/urandom)

# Generate a random number, and assign it to MY_ID
# This is not run initially.
SET_ID = $(eval MY_ID=$(GENERATE_ID))

# You can use .PHONY to tell make that we aren't building a target output file
.PHONY: mytarget
mytarget:
# This is empty when we begin
    @echo $(MY_ID)
# This recursively expands SET_ID, which calls the shell command and sets MY_ID
    $(SET_ID)
# This will now be a random number
    @echo $(MY_ID)
# Recursively expand SET_ID again, which calls the shell command (again) and sets MY_ID (again)
    $(SET_ID)
# This will now be a different random number
    @echo $(MY_ID)

A solution improving on the great one from @sparrow.

Let df, be your dataset, and mylist the list with the values you want to add to the dataframe.

Let's suppose you want to call your new column simply, new_column

First make the list into a Series:

column_values = pd.Series(mylist)

Then use the insert function to add the column. This function has the advantage to let you choose in which position you want to place the column. In the following example we will position the new column in the first position from left (by setting loc=0)

df.insert(loc=0, column='new_column', value=column_values)

maybe I'd go by this.

 SQL = SELECT REPLACE(myColumn, '""', '\'') FROM myTable

I used singlequotes because that's the one that registers string expressions in MySQL, or so I believe.

Hope that helps.

Basically, I want to check if a particular string contains AT LEAST day(1 through 31 or 01 through 31),month(1 through 12 or 01 through 12) and year(yyyy or yy) in any order, with any date separator , what will be the solution? So, if the value includes any parts of time, it should return true too. I could NOT be able to define a array of format.

When I was in a similar situation, here is what I did:

1. Gather all the formats my system is expected to support.
2. Looked at what is common or can be generalize.
3. Learned to create REGEX (It is an investment of time initially but pays off once you create one or two on your own). Also do not try to build REGEX for all formats in one go, follow incremental process.
4. I created REGEX to cover as many format as possible.
5. For few cases, not to make REGEX extra complex, I covered it through DateTime.Parse() method.
6. With the combination of both Parse as well as REGEX i was able to validate the input is correct/as expected.

This http://www.codeproject.com/Articles/13255/Validation-with-Regular-Expressions-Made-Simple was really helpful both for understanding as well as validation the syntax for each format.

My 2 cents if it helps....

WAMP is an acronym for Windows (OS), Apache (web-server), MySQL (database), PHP (language).

XAMPP and WampServer are both free packages of WAMP, with additional applications/tools, put together by different people. There are also other WAMPs such as UniformServer. And there are commercial WAMPs such as WampDeveloper (what I use).

Their differences are in the format/structure of the package, the configurations, and the included management applications.

IIS is a web-server application just like Apache is, except it's made by Microsoft and is Windows only (Apache runs on both Windows and Linux). IIS is also more geared towards using ASP.NET (vs. PHP) and "SQL Server" (vs. MySQL), though it can use PHP and MySQL too.

Just because @MartinCapodici 's comment is awesome I write here as an answer to give visibility.

All clockwise:

• WPF start West (left->top->right->bottom)
• Netscape (ie CSS) start North (top->right->bottom->left)

shape is a tuple that gives dimensions of the array..

>>> c = arange(20).reshape(5,4)
>>> c
array([[ 0,  1,  2,  3],
       [ 4,  5,  6,  7],
       [ 8,  9, 10, 11],
       [12, 13, 14, 15],
       [16, 17, 18, 19]])

c.shape[0] 
5

Gives the number of rows

c.shape[1] 
4

Gives number of columns

How about writing some color-based class in a global sass file, thus we don't need to care where variables are. Just like the following:

// base.scss 
@import "./_variables.scss";

.background-color{
    background: $bg-color;
}

and then, we can use the background-color class in any file. My point is that I don't need to import variable.scss in any file, just use it.

The setFirstResult and setMaxResults Query methods

For a JPA and Hibernate Query, the setFirstResult method is the equivalent of OFFSET, and the setMaxResults method is the equivalent of LIMIT:

List<Post> posts = entityManager
.createQuery(
    "select p " +
    "from Post p " +
    "order by p.createdOn ")
.setFirstResult(10)
.setMaxResults(10)
.getResultList();

The LimitHandler abstraction

The Hibernate LimitHandler defines the database-specific pagination logic, and as illustrated by the following diagram, Hibernate supports many database-specific pagination options:

Now, depending on the underlying relational database system you are using, the above JPQL query will use the proper pagination syntax.

MySQL

SELECT p.id AS id1_0_,
       p.created_on AS created_2_0_,
       p.title AS title3_0_
FROM post p
ORDER BY p.created_on
LIMIT ?, ?

PostgreSQL

SELECT p.id AS id1_0_,
       p.created_on AS created_2_0_,
       p.title AS title3_0_
FROM post p
ORDER BY p.created_on
LIMIT ?
OFFSET ?

SQL Server

SELECT p.id AS id1_0_,
       p.created_on AS created_on2_0_,
       p.title AS title3_0_
FROM post p
ORDER BY p.created_on
OFFSET ? ROWS 
FETCH NEXT ? ROWS ONLY

Oracle

SELECT *
FROM (
    SELECT 
        row_.*, rownum rownum_
    FROM (
        SELECT 
            p.id AS id1_0_,
            p.created_on AS created_on2_0_,
            p.title AS title3_0_
        FROM post p
        ORDER BY p.created_on
    ) row_
    WHERE rownum <= ?
)
WHERE rownum_ > ?

The advantage of using setFirstResult and setMaxResults is that Hibernate can generate the database-specific pagination syntax for any supported relational databases.

And, you are not limited to JPQL queries only. You can use the setFirstResult and setMaxResults method seven for native SQL queries.

Native SQL queries

You don't have to hardcode the database-specific pagination when using native SQL queries. Hibernate can add that to your queries.

So, if you're executing this SQL query on PostgreSQL:

List<Tuple> posts = entityManager
.createNativeQuery(
    "SELECT " +
    "   p.id AS id, " +
    "   p.title AS title " +
    "from post p " +
    "ORDER BY p.created_on", Tuple.class)
.setFirstResult(10)
.setMaxResults(10)
.getResultList();

Hibernate will transform it as follows:

SELECT p.id AS id,
       p.title AS title
FROM post p
ORDER BY p.created_on
LIMIT ?
OFFSET ?

Cool, right?

Beyond SQL-based pagination

Pagination is good when you can index the filtering and sorting criteria. If your pagination requirements imply dynamic filtering, it's a much better approach to use an inverted-index solution, like ElasticSearch.

I needed to do the same thing for a chart where you could select the period of the data that should be displayed.

Therefore I introduced the CSS class 'btn-group-radio' and used the following unobtrusive javascript one-liner:

// application.js
$(document).ready(function() {
  $('.btn-group-radio .btn').click(function() {
    $(this).addClass('active').siblings('.btn').removeClass('active');
  });
});

And here is the HTML:

<!-- some arbitrary view -->
<div class="btn-group btn-group-radio">
  <%= link_to '1W', charts_path('1W'), class: 'btn btn-default active', remote: true %>
  <%= link_to '1M', charts_path('1M'), class: 'btn btn-default', remote: true %>
  <%= link_to '3M', charts_path('3M'), class: 'btn btn-default', remote: true %>
  <%= link_to '6M', charts_path('6M'), class: 'btn btn-default', remote: true %>
  <%= link_to '1Y', charts_path('1Y'), class: 'btn btn-default', remote: true %>
  <%= link_to 'All', charts_path('all'), class: 'btn btn-default', remote: true %>
</div>

You can get a list of string from your number, by converting it to a string, and then splitting it with an empty string. The result will be an array of strings, each containing a digit:

const num = 124124124
const strArr = `${num}`.split("")

OR to build on this, map each string digit and convert them to a Number:

const intArr = `${num}`.split("").map(x => Number(x))

This error is often caused by incompatible jQuery versions. I encountered the same error with a foundation 6 repository. My repository was using jQuery 3, but foundation requires an earlier version. I then changed it and it worked.

If you look at the version of jQuery required by the foundation 5 dependencies it states "jquery": "~2.1.0".

Can you confirm that you are loading the correct version of jQuery?

I hope this helps.

I'm not sure what jQuery api you're looking at, but you should only have to specify id.

$('#thumb').removeAttr('id');

Or if you want to do this with a script:

sed -i 's/\r//' filename

Maven will not run your tests if the project has <packaging>pom</packaging>

You need to set the packaging to jar (or some other java artefact type) for the tests to run: <packaging>jar</packaging>

For some time now, you can also only rely on the data.table package and its IDate class plus associated functions. (Check ?as.IDate()). So, no need to additionally install lubridate.

require(data.table)

some_date <- c("01/02/1979", "03/04/1980")
month(as.IDate(some_date, '%d/%m/%Y')) # all data.table functions

You can have an auto-Incrementing column that is not the PRIMARY KEY, as long as there is an index (key) on it:

CREATE TABLE members ( 
  id int(11)  UNSIGNED NOT NULL AUTO_INCREMENT,
  memberid VARCHAR( 30 ) NOT NULL , 
  `time` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP , 
  firstname VARCHAR( 50 ) NULL , 
  lastname VARCHAR( 50 ) NULL , 
  PRIMARY KEY (memberid) ,
  KEY (id)                          --- or:    UNIQUE KEY (id)
) ENGINE = MYISAM; 

so this happened to me on windows recently. I fix it by following the following steps using a PowerShell with admin privileges:

1. delete node_modulesfolder
2. running npm install --global windows-build-tools
3. reinstalling node modules or node-sass with npm install

I have found the solution to this issue using ObjectDoesNotExist on this way

After this, my code works as I need

Thanks any way, your post help me to solve my issue

It doesn't "fail"; it just stops reading. It sees a lexical token as a "string".

Use std::getline:

int main()
{
   std::string name, title;

   std::cout << "Enter your name: ";
   std::getline(std::cin, name);

   std::cout << "Enter your favourite movie: ";
   std::getline(std::cin, title);

   std::cout << name << "'s favourite movie is " << title;
}

Note that this is not the same as std::istream::getline, which works with C-style char buffers rather than std::strings.

Update

Your edited question bears little resemblance to the original.

You were trying to getline into an int, not a string or character buffer. The formatting operations of streams only work with operator<< and operator>>. Either use one of them (and tweak accordingly for multi-word input), or use getline and lexically convert to int after-the-fact.

This should do it

replacements = {'zero':'0', 'temp':'bob', 'garbage':'nothing'}

with open('path/to/input/file') as infile, open('path/to/output/file', 'w') as outfile:
    for line in infile:
        for src, target in replacements.iteritems():
            line = line.replace(src, target)
        outfile.write(line)

EDIT: To address Eildosa's comment, if you wanted to do this without writing to another file, then you'll end up having to read your entire source file into memory:

lines = []
with open('path/to/input/file') as infile:
    for line in infile:
        for src, target in replacements.iteritems():
            line = line.replace(src, target)
        lines.append(line)
with open('path/to/input/file', 'w') as outfile:
    for line in lines:
        outfile.write(line)

Edit: If you are using Python 3.x, use replacements.items() instead of replacements.iteritems()

If your DataGridView's RightToLeft set to Yes then your data copy reversely. So you should use the below code to copy the data correctly.

private void copyAlltoClipboard()
{
    dgvItems.RightToLeft = RightToLeft.No;
    dgvItems.SelectAll();
    DataObject dataObj = dgvItems.GetClipboardContent();
    if (dataObj != null)
        Clipboard.SetDataObject(dataObj);
    dgvItems.RightToLeft = RightToLeft.Yes;
}

Do you mean these hex values?

.glyphicon-asterisk:before{content:"\2a";}
.glyphicon-plus:before{content:"\2b";}
.glyphicon-euro:before{content:"\20ac";}
...

You can find these in glyphicons.css here:

http://netdna.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap-glyphicons.css

You could use:

NSString *stringWithoutSpaces = [myString 
   stringByReplacingOccurrencesOfString:@" " withString:@""];

Try to delete the existing tomcat server in the server console. If you don't have the console then you can go to "Show view ->server", delete the server by right clicking on it, then add a new server.

The new method is:

[self dismissViewControllerAnimated:NO completion:nil];

The word modal has been removed; As it has been for the presenting API call:

[self presentViewController:vc animated:NO completion:nil];

The reasons were discussed in the 2012 WWDC Session 236 - The Evolution of View Controllers on iOS Video. Essentially, view controllers presented by this API are no longer always modal, and since they were adding a completion handler it was a good time to rename it.

In response to comment from Marc:

What's the best way to support all devices 4.3 and above? The new method doesn't work in iOS4, yet the old method is deprecated in iOS6.

I realize that this is almost a separate question, but I think it's worth a mention since not everyone has the money to upgrade all their devices every 3 years so many of us have some older (pre 5.0) devices. Still, as much as it pains me to say it, you need to consider if it is worth targeting below 5.0. There are many new and cool APIs not available below 5.0. And Apple is continually making it harder to target them; armv6 support is dropped from Xcode 4.5, for example.

To target below 5.0 (as long as the completion block is nil) just use the handy respondsToSelector: method.

if ([self respondsToSelector:@selector(presentViewController:animated:completion:)]){
    [self presentViewController:test animated:YES completion:nil];
} else {
    [self presentModalViewController:test animated:YES];
}

In response to another comment from Marc:

That could be quite a lot of If statements in my application!...I was thinking of creating a category that encapsulated this code, would creating a category on UIViewControler get me rejected?

and one from Full Decent:

...is there a way to manually cause that to not present a compiler warning?

Firstly, no, creating a category on UIViewController in and of itself will not get your app rejected; unless that category method called private APIs or something similar.

A category method is an exceedingly good place for such code. Also, since there would be only one call to the deprecated API, there would be only one compiler warning.

To address Full Decent's comment(question), yes you can suppress compiler warnings manually. Here is a link to an answer on SO on that very subject. A category method is also a great place to suppress a compiler warning, since you're only suppressing the warning in one place. You certainly don't want to go around silencing the compiler willy-nilly.

If I was to write a simple category method for this it might be something like this:

@implementation UIViewController (NJ_ModalPresentation)
-(void)nj_presentViewController:(UIViewController *)viewControllerToPresent animated:(BOOL)flag completion:(void (^)(void))completion{
    NSAssert(completion == nil, @"You called %@ with a non-nil completion. Don't do that!",NSStringFromSelector(_cmd));
    if ([self respondsToSelector:@selector(presentViewController:animated:completion:)]){
        [self presentViewController:viewControllerToPresent animated:flag completion:completion];
    } else {
#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wdeprecated-declarations"
        [self presentModalViewController:viewControllerToPresent animated:flag];
#pragma clang diagnostic pop
    }
}
@end

Use any of these

legend.spacing = unit(1,"cm")
legend.spacing.x = unit(1,"cm")
legend.spacing.y = unit(1,"cm")

I only have one thing to add that wasn't clear from the other answers (for completeness's sake).

You may also use the stars when calling the function. For example, say you have code like this:

>>> def foo(*args):
...     print(args)
...
>>> l = [1,2,3,4,5]

You can pass the list l into foo like so...

>>> foo(*l)
(1, 2, 3, 4, 5)

You can do the same for dictionaries...

>>> def foo(**argd):
...     print(argd)
...
>>> d = {'a' : 'b', 'c' : 'd'}
>>> foo(**d)
{'a': 'b', 'c': 'd'}

Can be achieved also with scriptrunner

ScriptRunner.exe -appvscript demoA.cmd arg1 arg2 -appvscriptrunnerparameters -wait -timeout=30 -rollbackonerror -appvscript demoB.ps1 arg3 arg4 -appvscriptrunnerparameters -wait -timeout=30 

Which also have some features as rollback , timeout and waiting.

The Invalidate() Method will cause a repaint.

Well id isn't really the root node: Login is.

It should just be a case of specifying the attributes (not tags, btw) using XmlElement.SetAttribute. You haven't specified how you're creating the file though - whether you're using XmlWriter, the DOM, or any other XML API.

If you could give an example of the code you've got which isn't working, that would help a lot. In the meantime, here's some code which creates the file you described:

using System;
using System.Xml;

class Test
{
    static void Main()
    {
        XmlDocument doc = new XmlDocument();
        XmlElement root = doc.CreateElement("Login");
        XmlElement id = doc.CreateElement("id");
        id.SetAttribute("userName", "Tushar");
        id.SetAttribute("passWord", "Tushar");
        XmlElement name = doc.CreateElement("Name");
        name.InnerText = "Tushar";
        XmlElement age = doc.CreateElement("Age");
        age.InnerText = "24";

        id.AppendChild(name);
        id.AppendChild(age);
        root.AppendChild(id);
        doc.AppendChild(root);

        doc.Save("test.xml");
    }
}

You can load the images at the beginning and change the css attributes to show every image.

var images = array();
for( url in your_urls_array ){
   var img = document.createElement( "img" );
   //here the image attributes ( width, height, position, etc )
   images.push( img );
}

function player( position )
{
  images[position-1].style.display = "none" //be careful working with the first position
  images[position].style.display = "block";
  //reset position if needed
  timer = setTimeOut( "player( position )", time );
}

In windows this scenario happens when Eclipse crashes without a clean shutdown it will have the local Jetty or Tomcat server keep running. When you reopen Eclipse and try to start server again this will lead to the "Address already in use: JVM_Bind"

You can solve this by opening Task Manager and find the javaw.exe process and ending it.

Then you can restart the server on Eclipse.

After some googling, I found the advice to do the following, and it worked:

Old Thread, But in VS 2015 Console.WriteLine does not Write to Output Window If "Enable the Visual Studio Hosting Process" does not Checked or its Disabled in Project Properties -> Debug tab

Based on ni-ko-o-kin's answer:

meassurements = ["years", "months", "weeks", "days", "hours", "minutes", "seconds"];
withPadding = (duration) => {
    var step = null;
    return meassurements.map((m) => duration[m]()).filter((n,i,a) => {
        var nonEmpty = Boolean(n);
        if (nonEmpty || step || i >= a.length - 2) {
            step = true;
        }
        return step;
    }).map((n) => ('0' + n).slice(-2)).join(':')
}

duration1 = moment.duration(1, 'seconds');
duration2 = moment.duration(7200, 'seconds');
duration3 = moment.duration(604800, 'seconds');

withPadding(duration1); // 00:01
withPadding(duration2); // 02:00:00
withPadding(duration3); // 01:07:00:00:00

The following code will help you to get the element of the mouse pointer. The resulted elements will display in the console.

document.addEventListener('mousemove', function(e) {
    console.log(document.elementFromPoint(e.pageX, e.pageY)); 
})

Bootstrap has column offsets, so if you want columns with equal width without specifying size use this.

<div class="row">
  <div class="col">col</div>
  <div class="col">col</div>
  <div class="col">col</div>
  <div class="col">col</div>
</div>

Also check out this link https://getbootstrap.com/docs/4.0/layout/grid/#all-breakpoints

the correct syntax is -

with t1
as
(select * from tab1
where conditions...
),
t2
as
(select * from tab2
where conditions...
(you can access columns of t1 here as well)
)
select * from t1, t2
where t1.col1=t2.col2;

A Modern Solution

Most of the proposed solutions here will break with nested tables or other elements inside your td elements. I frequently use other elements inside my tables, but only want to export the topmost table. I took some of the code found here from Calumah and added in some modern vanilla ES6 JS.

Using textContent is a better solution than innerText as innerText will return any HTML inside your td elements. However, even textContent will return the text from nested elements. An even better solution is to use custom data attributes on your td and pull the values for you CSV from there.

Happy coding!

function downloadAsCSV(tableEle, separator = ','){
    let csvRows = []
    //only get direct children of the table in question (thead, tbody)
    Array.from(tableEle.children).forEach(function(node){
        //using scope to only get direct tr of node
        node.querySelectorAll(':scope > tr').forEach(function(tr){
            let csvLine = []
            //again scope to only get direct children
            tr.querySelectorAll(':scope > td').forEach(function(td){
                //clone as to not remove anything from original
                let copytd = td.cloneNode(true)
                let data
                if(copytd.dataset.val) data = copytd.dataset.val.replace(/(\r\n|\n|\r)/gm, '')
                else {
                    Array.from(copytd.children).forEach(function(remove){
                        //remove nested elements before getting text
                        remove.parentNode.removeChild(remove)   
                    })
                    data = copytd.textContent.replace(/(\r\n|\n|\r)/gm, '')
                }
                data = data.replace(/(\s\s)/gm, ' ').replace(/"/g, '""')
                csvLine.push('"'+data+'"')
            })
            csvRows.push(csvLine.join(separator))
        })
    })
    var a = document.createElement("a")
    a.style = "display: none; visibility: hidden" //safari needs visibility hidden
    a.href = 'data:text/csv;charset=utf-8,' + encodeURIComponent(csvRows.join('\n'))
    a.download = 'testfile.csv'
    document.body.appendChild(a)
    a.click()
    a.remove()
}

Edit: cloneNode() updated to cloneNode(true) to get insides

You can try

<form action="product.php" method="get" name="frmProduct" id="frmProduct" enctype="multipart/form-data">

<input onclick="submitAction(this)" id="submit_value" type="button" name="submit_value" value="">

</form>

<script type="text/javascript">
function submitAction(element)
{
    element.form.submit();
}
</script>

Don't you have more than one form with the same name ?

Not exactly the case of this question but can be helpful. I got this exception when i call mkdirs() on new file instead of its parent

Refresh the page containing the script whilst the developer tools are open on the scripts tab. This will add a (program) entry in the file list which shows the html of the page including the script. From here you can add breakpoints.

You can see in here: http://apidock.com/rails/ActionView/Helpers/FormBuilder/select

Or here: http://apidock.com/rails/ActionView/Helpers/FormOptionsHelper/select

Select tag has maximun 4 agrument, and last agrument is html option, it mean you can put class, require, selection option in here.

= f.select :sms_category_id, @sms_category_collect, {}, {class: 'form-control', required: true, selected: @set}

Be careful with your routes. A "redirectTo" will remove|drop any query parameter.

const appRoutes: Routes [
 {path: "one", component: PageOneComponent},
 {path: "two", component: PageTwoComponent},
 {path: "", redirectTo: "/one", pathMatch: full},
 {path: "**", redirectTo: "/two"}
]

I called my main component with query parameters like "/main?param1=a&param2=b and assume that my query parameters arrive in the "ngOnInit()" method in the main component before the redirect forwarding takes effect.

But this is wrong. The redirect will came before, drop the query parameters away and call the ngOnInit() method in the main component without query parameters.

I changed the third line of my routes to

{path: "", component: PageOneComponent},

and now my query parameters are accessible in the main components ngOnInit and also in the PageOneComponent.

Use:

'00'[len(str(i)):] + str(i)

Or with the math module:

import math
'00'[math.ceil(math.log(i, 10)):] + str(i)

I was getting this exception when debugging in PyCharm, given that no breakpoint was being hit. To prevent it, I added a breakpoint just after the with block, and then it stopped happening.

I'm using iReport 2.0.2 to generate the jasper file.

I didn't found the hammer logo, but I have a menu create > compile in the menu bar who create the the jasper file in the iReport program files folder :

What you are passing to GETNAME is the value of myInput, not the definition of myInput itself. The only way to do that is with a lambda expression, for example:

var nameofVar = GETNAME(() => myInput);

and indeed there are examples of that available. However! This reeks of doing something very wrong. I would propose you rethink why you need this. It is almost certainly not a good way of doing it, and forces various overheads (the capture class instance, and the expression tree). Also, it impacts the compiler: without this the compiler might actually have chosen to remove that variable completely (just using the stack without a formal local).

If you're using Express, you can use this:

res.setHeader('Content-Type', 'application/json');
res.send(JSON.stringify({key:"value"}));

or just this

res.json({key:"value"});

I was struggling with a similar problem yesterday. I already had a "working" solution using jQuery UI's draggable together with jQuery Touch Punch, which are mentioned in other answers. However, using this method was causing weird bugs in some Android devices for me, and therefore I decided to write a small jQuery plugin that can make HTML elements draggable by using touch events instead of using a method that emulates fake mouse events.

The result of this is jQuery Draggable Touch which is a simple jQuery plugin for making elements draggable, that has touch devices as it's main target by using touch events (like touchstart, touchmove, touchend, etc.). It still has a fallback that uses mouse events if the browser/device doesn't support touch events.

I had the same issue, and yes I had my jquery included first followed by the jquery validate script. I had no idea what was wrong. Turns out I was using a validate url that had moved. I figured this out by doing the following:

1. Open firefox
2. Open firebug
3. Click the NET tab in firebug. This will show you all the resources that get loaded.
4. Load your page.
5. Check the loaded resources and see if both your jquery & jquery.validate.js loaded.

In my situation I had a 403 Forbidden error when trying to obtain (http://dev.jquery.com/view/trunk/plugins/validate/jquery.validate.js which is used in the example on http://rocketsquared.com/wiki/Plugins/Validation ).

Turns out the that link (http://dev.jquery.com/view/trunk/plugins/validate/jquery.validate.js) had moved to http://view.jquery.com/trunk/plugins/validate/jquery.validate.js (Firebug told me this when I loaded the file locally as opposed to on my web server).

NOTE: I tried using microsoft's CDN link also but it failed when I tried to load the javascript file in the browser with the correct url, there was some odd issue going on with the CDN site.

For me on Windows 10 none of those worked ... I had changed my local server from WAMP to Laragon and had to add the new path to the php.ini in the Environment Variables under:

Control Panel --> Advanced System Settings --> Environment Variables --> Path (double click) --> Browse... then navigate to the php.ini and click ok.

After that a reboot was needed and now composer works like a charm!

i think it's pretty easy. just use this css

.content {
   width: 100%;
   height:(what u wanna give);
   float: left;
   position: fixed;
   overflow: auto;
   overflow-y: auto;
   overflow-x: none;
}

after this just give this class to ur div just like -

<div class="content">your stuff goes in...</div>

wininet.dll returns both standard and non-standard status codes that are listed below.

401 - Unauthorized file
403 - Forbidden file
404 - File Not Found
500 - some inclusion or functions may missed
200 - Completed

12002 - Server timeout
12029,12030, 12031 - dropped connections (either web server or DB server)
12152 - Connection closed by server.
13030 - StatusText properties are unavailable, and a query attempt throws an exception

For the status code "zero" are you trying to do a request on a local webpage running on a webserver or without a webserver?

XMLHttpRequest status = 0 and XMLHttpRequest statusText = unknown can help you if you are not running your script on a webserver.

It is important to notice that in C# the char type is stored as Unicode UTF-16.

From ASCII equivalent integer to char

char c = (char)88;

or

char c = Convert.ToChar(88)

From char to ASCII equivalent integer

int asciiCode = (int)'A';

The literal must be ASCII equivalent. For example:

string str = "X?????????";
Console.WriteLine((int)str[0]);
Console.WriteLine((int)str[1]);

will print

X
3626

Extended ASCII ranges from 0 to 255.

From default UTF-16 literal to char

Using the Symbol

char c = 'X';

Using the Unicode code

char c = '\u0058';

Using the Hexadecimal

char c = '\x0058';

From http://pyyaml.org/wiki/PyYAMLDocumentation:

add_path_resolver(tag, path, kind) adds a path-based implicit tag resolver. A path is a list of keys that form a path to a node in the representation graph. Paths elements can be string values, integers, or None. The kind of a node can be str, list, dict, or None.

#!/usr/bin/env python
import yaml

class Person(yaml.YAMLObject):
  yaml_tag = '!person'

  def __init__(self, name):
    self.name = name

yaml.add_path_resolver('!person', ['Person'], dict)

data = yaml.load("""
Person:
  name: XYZ
""")

print data
# {'Person': <__main__.Person object at 0x7f2b251ceb10>}

print data['Person'].name
# XYZ

exponent is a 1D array. This means that exponent[0] is a scalar, and exponent[0][i] is trying to access it as if it were an array.

Did you mean to say:

L = identity(len(l))
for i in xrange(len(l)):
    L[i][i] = exponent[i]

or even

L = diag(exponent)

?

If you don't use a passphrase, then the private key is not encrypted with any symmetric cipher - it is output completely unprotected.

You can generate a keypair, supplying the password on the command-line using an invocation like (in this case, the password is foobar):

openssl genrsa -aes128 -passout pass:foobar 3072

However, note that this passphrase could be grabbed by any other process running on the machine at the time, since command-line arguments are generally visible to all processes.

A better alternative is to write the passphrase into a temporary file that is protected with file permissions, and specify that:

openssl genrsa -aes128 -passout file:passphrase.txt 3072

Or supply the passphrase on standard input:

openssl genrsa -aes128 -passout stdin 3072

You can also used a named pipe with the file: option, or a file descriptor.

To then obtain the matching public key, you need to use openssl rsa, supplying the same passphrase with the -passin parameter as was used to encrypt the private key:

openssl rsa -passin file:passphrase.txt -pubout

(This expects the encrypted private key on standard input - you can instead read it from a file using -in <file>).

Example of creating a 3072-bit private and public key pair in files, with the private key pair encrypted with password foobar:

openssl genrsa -aes128 -passout pass:foobar -out privkey.pem 3072
openssl rsa -in privkey.pem -passin pass:foobar -pubout -out privkey.pub

It's not clear what type of application you're going to develop (desktop, web, console...)

The general answer, if you're developing Windows.Forms application, is use of

System.Windows.Forms.Timer class. The benefit of this is that it runs on UI thread, so it's simple just define it, subscribe to its Tick event and run your code on every 15 second.

If you do something else then windows forms (it's not clear from the question), you can choose System.Timers.Timer, but this one runs on other thread, so if you are going to act on some UI elements from the its Elapsed event, you have to manage it with "invoking" access.

personally i use underscore for this kind of stuff... so

a = _.find(results,function(rw){ return rw.id == 2 });

then "a" would be the row that you wanted of your array where the id was equal to 2

Call a static method from an instance:

function Clazz() {};
Clazz.staticMethod = function() {
    alert('STATIC!!!');
};

Clazz.prototype.func = function() {
    this.constructor.staticMethod();
}

var obj = new Clazz();
obj.func(); // <- Alert's "STATIC!!!"

Simple Javascript Class Project: https://github.com/reduardo7/sjsClass

Subclass is to Class as Java is to Programming Language.

CodeIgniter returns result rows as objects, not arrays. From the user guide:

result()

---

This function returns the query result as an array of objects, or an empty array on failure.

You'll have to access the fields using the following notation:

foreach ($getvidids->result() as $row) {
    $vidid = $row->videoid;
}

Use the pandas.DataFrame.rename funtion. Check this link for description.

data.rename(columns = {'gdp': 'log(gdp)'}, inplace = True)

If you intend to rename multiple columns then

data.rename(columns = {'gdp': 'log(gdp)', 'cap': 'log(cap)', ..}, inplace = True)

Assuming your script is something like the below snippet and named testargs.ps1

param ([string]$w)
Write-Output $w

You can call this at the commandline as:

PowerShell.Exe -File C:\scripts\testargs.ps1 "Test String"

This will print "Test String" (w/o quotes) at the console. "Test String" becomes the value of $w in the script.

I do stuck with same problem at time of installing magento2 while it require ~7.3.0 but I have 7.4.1. So, I downgraded php version using this method.

Step 1: Download Php version from here nts version https://windows.php.net/downloads/releases/archives/ and paste this version to c:\xampp\ as named 'php71'

Step 2: Setup Virtual Host Environment and do some other changes. Go to "c:\xampp/\pache\conf\extra\httpd-vhosts.conf" and put code snippet at the end of line

<VirtualHost 127.0.0.1:80>
    DocumentRoot "C:/xampp/htdocs/magento/crashcourse/"
    ServerName magento2.test
    <Directory "C:/xampp/htdocs/magento/crashcourse/">
        Require all granted    
    </Directory>
    <FilesMatch "\.php$">
        SetHandler application/x-httpd-php71-cgi
    </FilesMatch>
</VirtualHost>

GO to "C:\Windows\System32\drivers\etc\hosts" then edit the file with using admin privileges then add the code at end of line.

127.0.0.1 magento2.test

Go to you Apache Config file "c:/xampp/apache/conf/extra/httpd-xampp.conf" and paste below code at end of the line

ScriptAlias /php71 "C:/xampp/php71"
Action application/x-httpd-php71-cgi /php71/php-cgi.exe
<Directory "C:/xampp/php71">
    AllowOverride None
    Options None
    Require all denied
    <Files "php-cgi.exe">
        Require all granted
    </Files>
    SetEnv PHPRC "C:/xampp/php71"
</Directory>

Now, all set. Go to url: http://magento2.test all work fine!

If you are using Reactive form you can set it to default like this:

In the form model, set the value to false. So if it's checked its value will be true else false

let form = this.formBuilder.group({
    is_known: [false]
})

//In HTML

 <mat-checkbox matInput formControlName="is_known">Known</mat-checkbox>

public  HttpURLConnection getHttpConnection(String url, String type){
        URL uri = null;
        HttpURLConnection con = null;
        try{
            uri = new URL(url);
            con = (HttpURLConnection) uri.openConnection();
            con.setRequestMethod(type); //type: POST, PUT, DELETE, GET
            con.setDoOutput(true);
            con.setDoInput(true);
            con.setConnectTimeout(60000); //60 secs
            con.setReadTimeout(60000); //60 secs
            con.setRequestProperty("Accept-Encoding", "Your Encoding");
            con.setRequestProperty("Content-Type", "Your Encoding");
        }catch(Exception e){
            logger.info( "connection i/o failed" );
        }
        return con;
}

Then in your code :

public void yourmethod(String url, String type, String reqbody){
    HttpURLConnection con = null;
    String result = null;
    try {
        con = conUtil.getHttpConnection( url , type);
    //you can add any request body here if you want to post
         if( reqbody != null){  
                con.setDoInput(true);
                con.setDoOutput(true);
                DataOutputStream out = new  DataOutputStream(con.getOutputStream());
                out.writeBytes(reqbody);
                out.flush();
                out.close();
            }
        con.connect();
        BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream()));
        String temp = null;
        StringBuilder sb = new StringBuilder();
        while((temp = in.readLine()) != null){
            sb.append(temp).append(" ");
        }
        result = sb.toString();
        in.close();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
        logger.error(e.getMessage());
    }
//result is the response you get from the remote side
}

Add items:

arr[0] = "product_1";
arr[1] = "100";
arr[2] = "10";
itm = new ListViewItem(arr);
listView1.Items.Add(itm);

Retrieve items:

productName = listView1.SelectedItems[0].SubItems[0].Text;
price = listView1.SelectedItems[0].SubItems[1].Text;
quantity = listView1.SelectedItems[0].SubItems[2].Text;

You need to set up the remote repository on your client:

git remote add origin ssh://myserver.com/path/to/project

It means you haven't assigned a provisioning profile to the configuration.

Usually it's because "Any iOS SDK" must have a profile and cannot be set to "Don't sign".

All this and more is answered in the TN2250 Tech Note about Code Signing and Troubleshooting.

I made a little helper function to do this and catch all malformed data

function convertToPounds(str) { 
    var n = Number.parseFloat(str);
    if(!str || isNaN(n) || n < 0) return 0;
    return n.toFixed(2);
}

Demo is here

I have created some simple function you can use to convert time to any timezone :

function convertTimeToLocal($datetime,$timezone='Europe/Dublin') {
        $given = new DateTime($datetime, new DateTimeZone("UTC"));
        $given->setTimezone(new DateTimeZone($timezone));
        $output = $given->format("Y-m-d"); //can change as per your requirement
        return $output;
}

            // How many parts do we have?
            var numPages = 100;
            // How many parts do we want per page?
            var perPage = 10;
    
            // When the document loads we're on page 1
            // So to start with... hide everything else
            pageParts.slice(perPage).hide();
            // Apply simplePagination to our placeholder
            $("#page-nav").pagination({

                    var start = perPage * (pageNum - 1);
                    var end = start + perPage;
    
                    // First hide all page parts

I have detected something different from the other answers. Reaching this exception in my project was the result of a corrupt compilation. Without making any changes, just forcing rebuild, it was fixed.

You simply need to upgrade your Tomcat version, to Tomcat 8.0.xx. Java8 <-> Tomcat8

This is the configuration that I have been using and it has always worked out well

None of these answers worked for me. This answer doesn't solve OP's issue but since this post is the only one that shows up on googling this issue, I'm sharing my answer here.

I came across this issue while writing unit tests for Android. The issue was that the activity that I was testing extended AppCompatActivity instead of Activity. To fix this, I was able to just replace AppCompatActivity with Activity since I didn't really need it. This might not be a viable solution for everyone, but hopefully knowing the root cause will help someone.

str.replace() does fixed replacements. Use re.sub() instead.

Here you go:

^[^<>]*$

This will test for string that has no < and no >

If you want to test for a string that may have < and >, but must also have something other you should use just

[^<>] (or ^.*[^<>].*$)

Where [<>] means any of < or > and [^<>] means any that is not of < or >.

And of course the mandatory link.

You can create style element and insert it into DOM

$("<style type='text/css'> .redbold{ color:#f00; font-weight:bold;} </style>").appendTo("head");
$("<div/>").addClass("redbold").text("SOME NEW TEXT").appendTo("body");
