For Juno: (With Source in E:\workspace and destination in C:\workspace)

1. Copy project directory in its entirety to the workspace directory. (e.g. Copy E:\workspace\HelloWorld C:\workspace\helloWorld)

2. Start Eclipse.

3. Perform: File --> Import

4. Select: General -- > "Existing Project into Workspace"

5. "Next >"

6. Check "Select root Directory"

7. Select with "Browse Button"

8. Select "C:\workspace"

9. A list of existing projects will appear. Just check the ones that are in Bold (To Be Imported) then press the "Finish" button.

Review the Package Explorer and your copied projects should now be there.

I believe the only way to do this it to add the style as a new CSS declaration with the '!important' suffix. The easiest way to do this is to append a new <style> element to the head of document:

function addNewStyle(newStyle) {
    var styleElement = document.getElementById('styles_js');
    if (!styleElement) {
        styleElement = document.createElement('style');
        styleElement.type = 'text/css';
        styleElement.id = 'styles_js';
        document.getElementsByTagName('head')[0].appendChild(styleElement);
    }
    styleElement.appendChild(document.createTextNode(newStyle));
}

addNewStyle('td.EvenRow a {display:inline !important;}')

The rules added with the above method will (if you use the !important suffix) override other previously set styling. If you're not using the suffix then make sure to take concepts like 'specificity' into account.

Use scrollTop() to get or set the scroll position.

Update for iOS9.2.1 and Xcode 7.2.1

If you get this error when building to a device in Xcode:

On your device, tap the app icon that would have just been added from your attempt at building the app and you should see this:

Next, on your device, go to Settings --> General --> Device Management, and you will see this page:

Select the profile you are using with Xcode, and you should see this page:

Click Trust "[email protected]" then click Trust on the next popup.

Go back to Xcode and re-run your project and it should build the app to your device.

Marek Sebera's is great most of the time, but if you're like me and find that you need to check the iOS version frequently, you don't want to constantly run a macro in memory because you'll experience a very slight slowdown, especially on older devices.

Instead, you want to compute the iOS version as a float once and store it somewhere. In my case, I have a GlobalVariables singleton class that I use to check the iOS version in my code using code like this:

if ([GlobalVariables sharedVariables].iOSVersion >= 6.0f) {
    // do something if iOS is 6.0 or greater
}

To enable this functionality in your app, use this code (for iOS 5+ using ARC):

GlobalVariables.h:

@interface GlobalVariables : NSObject

@property (nonatomic) CGFloat iOSVersion;

    + (GlobalVariables *)sharedVariables;

@end

GlobalVariables.m:

@implementation GlobalVariables

@synthesize iOSVersion;

+ (GlobalVariables *)sharedVariables {
    // set up the global variables as a static object
    static GlobalVariables *globalVariables = nil;
    // check if global variables exist
    if (globalVariables == nil) {
        // if no, create the global variables class
        globalVariables = [[GlobalVariables alloc] init];
        // get system version
        NSString *systemVersion = [[UIDevice currentDevice] systemVersion];
        // separate system version by periods
        NSArray *systemVersionComponents = [systemVersion componentsSeparatedByString:@"."];
        // set ios version
        globalVariables.iOSVersion = [[NSString stringWithFormat:@"%01d.%02d%02d", \
                                       systemVersionComponents.count < 1 ? 0 : \
                                       [[systemVersionComponents objectAtIndex:0] integerValue], \
                                       systemVersionComponents.count < 2 ? 0 : \
                                       [[systemVersionComponents objectAtIndex:1] integerValue], \
                                       systemVersionComponents.count < 3 ? 0 : \
                                       [[systemVersionComponents objectAtIndex:2] integerValue] \
                                       ] floatValue];
    }
    // return singleton instance
    return globalVariables;
}

@end

Now you're able to easily check the iOS version without running macros constantly. Note in particular how I converted the [[UIDevice currentDevice] systemVersion] NSString to a CGFloat that is constantly accessible without using any of the improper methods many have already pointed out on this page. My approach assumes the version string is in the format n.nn.nn (allowing for later bits to be missing) and works for iOS5+. In testing, this approach runs much faster than constantly running the macro.

Hope this helps anyone experiencing the issue I had!

The DBHelper class is what handles the opening and closing of sqlite databases as well sa creation and updating, and a decent article on how it all works is here. When I started android it was very useful (however I've been objective-c lately, and forgotten most of it to be any use.

I think there are two different things here. The first one is that normal SSH authentication requires the user to put the account's password (where the account password will be authenticated against different methods, depending on the sshd configuration).

You can avoid putting that password using certificates. With certificates you still have to put a password, but this time is the password of your private key (that's independent of the account's password).

To do this you can follow the instructions pointed out by steveth45:

With Public Key Authentication.

If you want to avoid putting the certificate's password every time then you can use ssh-agent, as pointed out by DigitalRoss

The exact way you do this depends on Unix vs Windows, but essentially you need to run ssh-agent in the background when you log in, and then the first time you log in, run ssh-add to give the agent your passphrase. All ssh-family commands will then consult the agent and automatically pick up your passphrase.

Start here: man ssh-agent.

The only problem of ssh-agent is that, on *nix at least, you have to put the certificates password on every new shell. And then the certificate is "loaded" and you can use it to authenticate against an ssh server without putting any kind of password. But this is on that particular shell.

With keychain you can do the same thing as ssh-agent but "system-wide". Once you turn on your computer, you open a shell and put the password of the certificate. And then, every other shell will use that "loaded" certificate and your password will never be asked again until you restart your PC.

Gnome has a similar application, called Gnome Keyring that asks for your certificate's password the first time you use it and then it stores it securely so you won't be asked again.

Try this, this works for my code name is a String:

cursor = rdb.query(true, TABLE_PROFILE, new String[] { ID,
    REMOTEID, FIRSTNAME, LASTNAME, EMAIL, GENDER, AGE, DOB,
    ROLEID, NATIONALID, URL, IMAGEURL },                    
    LASTNAME + " like ?", new String[]{ name+"%" }, null, null, null, null);

You can use ES6 backtick syntax too

<a href={`/customer/${item._id}`} >{item.get('firstName')} {item.get('lastName')}</a>

For anyone meaning to do this more reliably for different Minecraft versions, I have a Python script (adapted from parts of minecraft-launcher-lib) that does the job very nicely

Besides setting some basic variables near the top after the functions, it calls a get_classpath that goes through for example ~/.minecraft/versions/1.16.5/1.16.5.json, and loops over the libraries array, checking to see if each object (within the array), is supposed to be added to the classpath (cp variable). whether this library is added to the java classpath is governed by the should_use_library function, deterministic based on the computer's architecture and operating system. finally, some jarfiles that are platform specific have extra things prepended to them (ex. natives-linux in org/lwjgl/lwjgl/3.2.1/lwjgl-3.2.1-natives-linux.jar). this extra prepended string is handled by get_natives_string and is empty if it doesn't apply to the current library

In swift 3 use:

Using static will not help your case.

Using synchronize locks a variable when it is in use by another thread.

You should use volatile keyword to keep the variable updated among all threads.

Using volatile is yet another way (like synchronized, atomic wrapper) of making class thread safe. Thread safe means that a method or class instance can be used by multiple threads at the same time without any problem.

If you're happy to ignore the time portion in the columns, DATEDIFF() will give you the difference you're looking for in days.

SELECT DATEDIFF('2010-10-08 18:23:13', '2010-09-21 21:40:36') AS days;

As Pax rightly said, measure, don't guess. That what I did for DNSwitness and the results were suprising: the ideal number of threads was much higher than I thought, something like 15,000 threads to get the fastest results.

Of course, it depends on many things, that's why you must measure yourself.

Quick solution:

1. add code to main function:

   String log4jConfPath = "/path/to/log4j.properties";
   PropertyConfigurator.configure(log4jConfPath);
   

2. create a file named log4j.properties at /path/to

   log4j.rootLogger=INFO, stdout
   log4j.appender.stdout=org.apache.log4j.ConsoleAppender
   log4j.appender.stdout.Target=System.out

As to "how do you calculate" Big O, this is part of Computational complexity theory. For some (many) special cases you may be able to come with some simple heuristics (like multiplying loop counts for nested loops), esp. when all you want is any upper bound estimation, and you do not mind if it is too pessimistic - which I guess is probably what your question is about.

If you really want to answer your question for any algorithm the best you can do is to apply the theory. Besides of simplistic "worst case" analysis I have found Amortized analysis very useful in practice.

This code is actually used to add values to the dictionary and through the data to an Array According to the Key.

NSMutableArray *arr = [[NSMutableArray alloc]init];
NSDictionary *dicto = [[NSMutableDictionary alloc]initWithObjectsAndKeys:@"Hello",@"StackOverFlow",@"Key1",@"StackExchange",@"Key2", nil];
NSLog(@"The dictonary is = %@", dicto);
arr = [dicto valueForKey:@"Key1"];
NSLog(@"The array is = %@", arr);

I found a better solution on the Chrome product forums by a user called Gary. The original thread is here.

Navigate to C:\Windows\System32\GroupPolicy

Open each subdirectory there and change the *.pol files to *.sav, E.g. registry.pol becomes registry.sav.

Hit Windows-Key + R, type the following in the box and hit enter

reg delete HKEY_LOCAL_MACHINE\SOFTWARE\Google\Chrome

In the command promt window that opens type: Yes and press Enter.

Restart Google Chrome and check whether you can change the search engine.

I just had this on OSX running brew and [email protected].

I do this to make sure they remember to print landscape, which is necessary for a lot of pages on a lot of printers.

<a href="javascript:alert('Please be sure to set your printer to Landscape.');window.print();">Print Me...</a>

or

<body onload="alert('Please be sure to set your printer to Landscape.');window.print();">
etc.
</body>

Download the server response as an array buffer. Store it as a Blob using the content type from the server (which should be application/vnd.openxmlformats-officedocument.spreadsheetml.sheet):

var httpPromise = this.$http.post(server, postData, { responseType: 'arraybuffer' });
httpPromise.then(response => this.save(new Blob([response.data],
    { type: response.headers('Content-Type') }), fileName));

Save the blob to the user's device:

save(blob, fileName) {
    if (window.navigator.msSaveOrOpenBlob) { // For IE:
        navigator.msSaveBlob(blob, fileName);
    } else { // For other browsers:
        var link = document.createElement('a');
        link.href = window.URL.createObjectURL(blob);
        link.download = fileName;
        link.click();
        window.URL.revokeObjectURL(link.href);
    }
}

You can do like this:

INSERT INTO DENI/FRIEN01P 
SELECT 
   RCRDID+112,
   PROFESION,
   NAME,
   SURNAME,
   AGE, 
   RCRDTYP, 
   RCRDLCU, 
   RCRDLCT, 
   RCRDLCD 
FROM 
   FRIEN01P      

There instead of 112 you should put a number of the maximum id in table DENI/FRIEN01P.

I see that you are looking for an implementation of the problem more than solving that error. Here you have a possible solution:

from itertools import chain

def involved(courses, person):
    courses_info = chain.from_iterable(x.values() for x in courses.values())
    return filter(lambda x: x['teacher'] == person, courses_info)

print involved(courses, 'Dave')

The first thing I do is getting the list of the courses and then filter by teacher's name.

There are two cases in which this error is raised.

1. You didn't declare the variable which is used
2. You didn't create the instances of the class

As others have said, it is valid.

There are some downsides to each approach though:

href="#" adds an extra entry to the browser history (which is annoying when e.g. back-buttoning).

href="" reloads the page

href="javascript:;" does not seem to have any problems (other than looking messy and meaningless) - anyone know of any?

If pip doesn't come with your installation of python 3.6, this may work:

wget https://bootstrap.pypa.io/get-pip.py
sudo python3.6 get-pip.py

then you can python -m install

As a workaround to force the evaluation of the SELECT clause before the WHERE clause, you could put the former in a sub-query while the latter remains in the main query:

SELECT * FROM (
  SELECT (InvoiceTotal - PaymentTotal - CreditTotal) AS BalanceDue
  FROM Invoices) AS temp
WHERE BalanceDue > 0
  

You can create spinner by these simple steps

first create spinner in xml

<Spinner
        android:id="@+id/select"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:textColor="#070707"></Spinner>

now create string arary in values

 <string-array name="itemselect">
    <item>Repurchase</item>
    <item>Coupons</item>
</string-array>

now initialized in java file

public class MemberCart_Activity extends AppCompatActivity {

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

 
    select=findViewById(R.id.select);
 ArrayAdapter<String> myadapter=new ArrayAdapter<String>(Main_Activity.this,android.R.layout.simple_list_item_1,getResources().getStringArray(R.array.itemselect));
    myadapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    select.setAdapter(myadapter);

In Pass By Reference You only add "ref" in the function parameters and one more thing you should be declaring function "static" because of main is static(#public void main(String[] args))!

namespace preparation
{
  public  class Program
    {
      public static void swap(ref int lhs,ref int rhs)
      {
          int temp = lhs;
          lhs = rhs;
          rhs = temp;
      }
          static void Main(string[] args)
        {
            int a = 10;
            int b = 80;

  Console.WriteLine("a is before sort " + a);
            Console.WriteLine("b is before sort " + b);
            swap(ref a, ref b);
            Console.WriteLine("");
            Console.WriteLine("a is after sort " + a);
            Console.WriteLine("b is after sort " + b);  
        }
    }
}

The sample config you provided is actually valid YAML. In fact, YAML meets all of your demands, is implemented in a large number of languages, and is extremely human friendly. I would highly recommend you use it. The PyYAML project provides a nice python module, that implements YAML.

To use the yaml module is extremely simple:

import yaml
config = yaml.safe_load(open("path/to/config.yml"))

Use the .Replace() method

Line.Replace("\n", "whatever you want to replace with");

In IPython (jupyter) 7.3 and later, there is a magic %pip and %conda command that will install into the current kernel (rather than into the instance of Python that launched the notebook).

%pip install geocoder

In earlier versions, you need to use sys to fix the problem like in the answer by FlyingZebra1

import sys
!{sys.executable} -m pip install geocoder

This does work for a specific delimiter for a specific amount of characters between the delimiter. I had many issues attempting to use this in a for each loop where the position changed but the delimiter was the same. For example I was using the backslash as the delimiter and wanted to only use everything to the right of the backslash. The issue was that once the position was defined (71 characters from the beginning) it would use $pos as 71 every time regardless of where the delimiter actually was in the script. I found another method of using a delimiter and .split to break things up then used the split variable to call the sections For instance the first section was $variable[0] and the second section was $variable[1].

To make sure a click only actions once use this:

$(".bet").unbind().click(function() {

I know nothing about Jenkins, but it looks like you are trying to access environment variables using some form of unix syntax - that won't work.

If the name of the variable is WORKSPACE, then the value is expanded in Windows batch using
%WORKSPACE%. That form of expansion is performed at parse time. For example, this will print to screen the value of WORKSPACE

echo %WORKSPACE%

If you need the value at execution time, then you need to use delayed expansion !WORKSPACE!. Delayed expansion is not normally enabled by default. Use SETLOCAL EnableDelayedExpansion to enable it. Delayed expansion is often needed because blocks of code within parentheses and/or multiple commands concatenated by &, &&, or || are parsed all at once, so a value assigned within the block cannot be read later within the same block unless you use delayed expansion.

setlocal enableDelayedExpansion
set WORKSPACE=BEFORE
(
  set WORKSPACE=AFTER
  echo Normal Expansion = %WORKSPACE%
  echo Delayed Expansion = !WORKSPACE!
)

The output of the above is

Normal Expansion = BEFORE
Delayed Expansion = AFTER

Use HELP SET or SET /? from the command line to get more information about Windows environment variables and the various expansion options. For example, it explains how to do search/replace and substring operations.

        ).run {
            maxDate?.time?.also { datePicker.maxDate = it }
            show()
        }
    }
}

Usage:

In Activity:

editText.transformIntoDatePicker(this, "MM/dd/yyyy")
editText.transformIntoDatePicker(this, "MM/dd/yyyy", Date())

In Fragments:

editText.transformIntoDatePicker(requireContext(), "MM/dd/yyyy")
editText.transformIntoDatePicker(requireContext(), "MM/dd/yyyy", Date())

r = requests.post(url, data=json.dumps(payload), headers=headers)

You just need to create a dict with your headers (key: value pairs where the key is the name of the header and the value is, well, the value of the pair) and pass that dict to the headers parameter on the .get or .post method.

So more specific to your question:

headers = {'foobar': 'raboof'}
requests.get('http://himom.com', headers=headers)

VBA subs are no macros. A VBA sub can be a macro, but it is not a must.

The term "macro" is only used for recorded user actions. from these actions a code is generated and stored in a sub. This code is simple and do not provide powerful structures like loops, for example Do .. until, for .. next, while.. do, and others.

The more elegant way is, to design and write your own VBA code without using the macro features!

VBA is a object based and event oriented language. Subs, or bette call it "sub routines", are started by dedicated events. The event can be the pressing of a button or the opening of a workbook and many many other very specific events.

If you focus to VB6 and not to VBA, then you can state, that there is always a main-window or main form. This form is started if you start the compiled executable "xxxx.exe".

In VBA you have nothing like this, but you have a XLSM file wich is started by Excel. You can attach some code to the Workbook_Open event. This event is generated, if you open your desired excel file which is called a workbook. Inside the workbook you have worksheets.

It is useful to get more familiar with the so called object model of excel. The workbook has several events and methods. Also the worksheet has several events and methods.

In the object based model you have objects, that have events and methods. methods are action you can do with a object. events are things that can happen to an object. An objects can contain another objects, and so on. You can create new objects, like sheets or charts.

The Easiest way example to show you how to do that is :

Code :

>>> points = 19.5 >>> total = 22 >>>'Correct answers: {:.2%}'.format(points/total) `

Output : Correct answers: 88.64%

I ran into the same problem and found that the documentation has example for this type of scenario (where we write STDERR TO STDOUT and always exit successfully with return code 0) without causing/catching an exception.

output = subprocess.check_output("ping -c 2 -W 2 1.1.1.1; exit 0", stderr=subprocess.STDOUT, shell=True)

Now, you can use standard string function find to check the output string output.

As of lodash 3.5.0 you can use sortByOrder (renamed orderBy in v4.3.0):

var data = _.sortByOrder(array_of_objects, ['type','name'], [true, false]);

Since version 3.10.0 you can even use standard semantics for ordering (asc, desc):

var data = _.sortByOrder(array_of_objects, ['type','name'], ['asc', 'desc']);

In version 4 of lodash this method has been renamed orderBy:

var data = _.orderBy(array_of_objects, ['type','name'], ['asc', 'desc']);

Just adding another idea you could use a child selector to get immediate children

document.querySelectorAll(".parent > .child1");

should return all the immediate children with class .child1

I had this error and all the configurations mentioned above were correct however I was still getting "The client and service bindings may be mismatched" error.

What resolved my error, was matching the messageEncoding attribute values in the following node of service and client config files. They were different in mine, service was Text and client Mtom. Changing service to Mtom to match client's, resolved the issue.

<configuration>
  <system.serviceModel>
      <bindings>
           <basicHttpBinding>
              <binding name="BasicHttpBinding_IMySevice" ... messageEncoding="Mtom">
              ...
              </binding>
           </basicHttpBinding>
      </bindings>
  </system.serviceModel>
</configuration>

You can send it as raw xml

If you declare the paramater2 as XElement data type

boost::is_any_of

Strip for all characters from one string that appear in another given string:

#include <cassert>

#include <boost/range/algorithm/remove_if.hpp>
#include <boost/algorithm/string/classification.hpp>

int main() {
    std::string str = "a_bc0_d";
    str.erase(boost::remove_if(str, boost::is_any_of("_0")), str.end());
    assert((str == "abcd"));
}

Tested in Ubuntu 16.04, Boost 1.58.

I find the answers not satisfactory so I'll add my two cents.

Let's analyze the following cases:

Erroneous usage

int& getInt()
{
    int x = 4;
    return x;
}

This is obviously error

int& x = getInt(); // will refer to garbage

Usage with static variables

int& getInt()
{
   static int x = 4;
   return x;
}

This is right, because static variables are existant throughout lifetime of a program.

int& x = getInt(); // valid reference, x = 4

This is also quite common when implementing Singleton pattern

Class Singleton
{
    public:
        static Singleton& instance()
        {
            static Singleton instance;
            return instance;
        };

        void printHello()
        {
             printf("Hello");
        };

}

Usage:

 Singleton& my_sing = Singleton::instance(); // Valid Singleton instance
 my_sing.printHello();  // "Hello"

Operators

Standard library containers depend heavily upon usage of operators which return reference, for example

T & operator*();

may be used in the following

std::vector<int> x = {1, 2, 3}; // create vector with 3 elements
std::vector<int>::iterator iter = x.begin(); // iterator points to first element (1)
*iter = 2; // modify first element, x = {2, 2, 3} now

Quick access to internal data

There are times when & may be used for quick access to internal data

Class Container
{
    private:
        std::vector<int> m_data;

    public:
        std::vector<int>& data()
        {
             return m_data;
        }
}

with usage:

Container cont;
cont.data().push_back(1); // appends element to std::vector<int>
cont.data()[0] // 1

HOWEVER, this may lead to pitfall such as this:

Container* cont = new Container;
std::vector<int>& cont_data = cont->data();
cont_data.push_back(1);
delete cont; // This is bad, because we still have a dangling reference to its internal data!
cont_data[0]; // dangling reference!

I had an issue with the downscaleImage() function posted above by @daniel-allen-langdon in that the image.width and image.height properties are not available immediately because the image load is asynchronous.

Please see updated TypeScript example below that takes this into account, uses async functions, and resizes the image based on the longest dimension rather than just the width

function getImage(dataUrl: string): Promise<HTMLImageElement> 
{
    return new Promise((resolve, reject) => {
        const image = new Image();
        image.src = dataUrl;
        image.onload = () => {
            resolve(image);
        };
        image.onerror = (el: any, err: ErrorEvent) => {
            reject(err.error);
        };
    });
}

export async function downscaleImage(
        dataUrl: string,  
        imageType: string,  // e.g. 'image/jpeg'
        resolution: number,  // max width/height in pixels
        quality: number   // e.g. 0.9 = 90% quality
    ): Promise<string> {

    // Create a temporary image so that we can compute the height of the image.
    const image = await getImage(dataUrl);
    const oldWidth = image.naturalWidth;
    const oldHeight = image.naturalHeight;
    console.log('dims', oldWidth, oldHeight);

    const longestDimension = oldWidth > oldHeight ? 'width' : 'height';
    const currentRes = longestDimension == 'width' ? oldWidth : oldHeight;
    console.log('longest dim', longestDimension, currentRes);

    if (currentRes > resolution) {
        console.log('need to resize...');

        // Calculate new dimensions
        const newSize = longestDimension == 'width'
            ? Math.floor(oldHeight / oldWidth * resolution)
            : Math.floor(oldWidth / oldHeight * resolution);
        const newWidth = longestDimension == 'width' ? resolution : newSize;
        const newHeight = longestDimension == 'height' ? resolution : newSize;
        console.log('new width / height', newWidth, newHeight);

        // Create a temporary canvas to draw the downscaled image on.
        const canvas = document.createElement('canvas');
        canvas.width = newWidth;
        canvas.height = newHeight;

        // Draw the downscaled image on the canvas and return the new data URL.
        const ctx = canvas.getContext('2d')!;
        ctx.drawImage(image, 0, 0, newWidth, newHeight);
        const newDataUrl = canvas.toDataURL(imageType, quality);
        return newDataUrl;
    }
    else {
        return dataUrl;
    }

}

JohannesD's answer is correct, but I feel it isn't entirely clear on an aspect of the problem.

The example he gives declares and initializes the variable i in case 1, and then tries to use it in case 2. His argument is that if the switch went straight to case 2, i would be used without being initialized, and this is why there's a compilation error. At this point, one could think that there would be no problem if variables declared in a case were never used in other cases. For example:

switch(choice) {
    case 1:
        int i = 10; // i is never used outside of this case
        printf("i = %d\n", i);
        break;
    case 2:
        int j = 20; // j is never used outside of this case
        printf("j = %d\n", j);
        break;
}

One could expect this program to compile, since both i and j are used only inside the cases that declare them. Unfortunately, in C++ it doesn't compile: as Ciro Santilli ???? ???? ??? explained, we simply can't jump to case 2:, because this would skip the declaration with initialization of i, and even though case 2 doesn't use i at all, this is still forbidden in C++.

Interestingly, with some adjustments (an #ifdef to #include the appropriate header, and a semicolon after the labels, because labels can only be followed by statements, and declarations do not count as statements in C), this program does compile as C:

// Disable warning issued by MSVC about scanf being deprecated
#ifdef _MSC_VER
#define _CRT_SECURE_NO_WARNINGS
#endif

#ifdef __cplusplus
#include <cstdio>
#else
#include <stdio.h>
#endif

int main() {

    int choice;
    printf("Please enter 1 or 2: ");
    scanf("%d", &choice);

    switch(choice) {
        case 1:
            ;
            int i = 10; // i is never used outside of this case
            printf("i = %d\n", i);
            break;
        case 2:
            ;
            int j = 20; // j is never used outside of this case
            printf("j = %d\n", j);
            break;
    }
}

Thanks to an online compiler like http://rextester.com you can quickly try to compile it either as C or C++, using MSVC, GCC or Clang. As C it always works (just remember to set STDIN!), as C++ no compiler accepts it.

According to this posting by the lead Jenkins developer, Kohsuke Kawaguchi, in 2009, there is no group support for the built-in Jenkins user database. Group support is only usable when integrating Jenkins with LDAP or Active Directory. This appears to be the same in 2012.

However, as Vadim wrote in his answer, you don't need group support for the built-in Jenkins user database, thanks to the Role strategy plug-in.

Very simple, you close it :)

This is an older version but the links are from the Microsoft servers, it should be safe. The link for 32-bit version is also in a previous answer but the version number i get on the install is different, maybe the same link is updated with a newer version since 2013.

I tested the 64 bit debugger with a 64 bit program that was compiled some years ago (~2012) and it works. Test is done on Windows 10 Pro 64 bit (v2004 Build 19041.207).

This way worked for me:

adding the path that you like:

export PYTHONPATH=$PYTHONPATH:/path/you/want/to/add

checking: you can run 'export' cmd and check the output or you can check it using this cmd:

python -c "import sys; print(sys.path)"

To have the exact same output as you need, you need to format the file like that :

a very long string..........\t     112232432\t     anotherfield\n
a smaller string\t      123124343\t     anotherfield\n

And then using :

$ column -t -s $'\t' FILE
a very long string..........  112232432  anotherfield
a smaller string              123124343  anotherfield

Also, you do not have to use nested CASEs. You can use several WHEN-THEN lines and the ELSE line is also optional eventhough I recomend it

CASE 
   WHEN [condition.1] THEN [expression.1]
   WHEN [condition.2] THEN [expression.2]
   ...
   WHEN [condition.n] THEN [expression.n]
   ELSE [expression] 
END

It sounds like the best way is for you to iterate over entries using map.entrySet() since map.containsValue() probably does this anyway.

So ... more digging, with the result. It seems that although I ran one process normal and one "As Administrator", I had UAC off. Turning UAC to medium allowed me to see different results. Basically, it all boils down to integrity levels, which are 5.

Browsers, for example, run at Low Level (1), while services (System user) run at System Level (4). Everything is very well explained in Windows Integrity Mechanism Design . When UAC is enabled, processes are created with Medium level (SID S-1-16-8192 AKA 0x2000 is added) while when "Run as Administrator", the process is created with High Level (SID S-1-16-12288 aka 0x3000).

So the correct ACCESS_TOKEN for a normal user (Medium Integrity level) is:

0:000:x86> !token

Previous answers point out correctly that you can only do this with the standard JDK tools by converting the JKS file into PKCS #12 format first. If you're interested, I put together a compact utility to import OpenSSL-derived keys into a JKS-formatted keystore without having to convert the keystore to PKCS #12 first: http://commandlinefanatic.com/cgi-bin/showarticle.cgi?article=art049

You would use the linked utility like this:

$ openssl req -x509 -newkey rsa:2048 -keyout localhost.key -out localhost.csr -subj "/CN=localhost"

(sign the CSR, get back localhost.cer)

$ openssl rsa -in localhost.key -out localhost.rsa
Enter pass phrase for localhost.key:
writing RSA key
$ java -classpath . KeyImport -keyFile localhost.rsa -alias localhost -certificateFile localhost.cer -keystore localhost.jks -keystorePassword changeit -keystoreType JKS -keyPassword changeit

I would use it at every opportunity. See When do you use Java's @Override annotation and why?

Personally, I would shorten it a touch too if all you need is the columns:

For i = LBound(arr1) To UBound(arr1)
    Sheets("SheetA").Columns(arr1(i)).Copy
    Sheets("SheetB").Columns(arr2(i)).PasteSpecial xlPasteValues
    Application.CutCopyMode = False
Next

as from this code snippet, there isnt much point in lastrow or firstrowDB

You may use the following extension method:

public static class CharExtensions
    {
        public static int CharToInt(this char c)
        {
            if (c < '0' || c > '9')
                throw new ArgumentException("The character should be a number", "c");

            return c - '0';
        }
    }

Notepad++ comes equipped with a Edit -> Column "Alt+C" Editor which can work on a rectangular selection in two different ways: Coledit.png inserting some fixed text on every line including and following the current line, at the column of the insertion point (aka caret). Initially selected text is left untouched. As the picture illustrates, a linear series of numbers can be inserted in the same manner. The starting value and increment are to be provided. Left padding with zeroes is an option, and the number may be entered in base 2, 8, 10 or 16 - this is how the computed values will be displayed too, padding being based on the largest.

Just change + to -:

str = str.replace(/[^a-z0-9-]/g, "");

You can read it as:

1. [^ ]: match NOT from the set
2. [^a-z0-9-]: match if not a-z, 0-9 or -
3. / /g: do global match

I have found that you have to comment out the namespace wrapping the the class at time when moving between version of Visual Studio:

'Namespace FormsAuth

'End Namespace

and at other times, I have to uncomment the namespace.

This happened to me several times when other developers edited the same solution using a different version of VS and/or I moved (copied) the solution to another location

In your example, it’s fine as it is: it’s simple and works. The only things I’d suggest are:

1. validating the data POSTed

2. make sure your API is sending the Content-Type header to tell the client to expect a JSON response:

   header('Content-Type: application/json');
   echo json_encode($response);
   

Other than that, an API is something that takes an input and provides an output. It’s possible to “over-engineer” things, in that you make things more complicated that need be.

If you wanted to go down the route of controllers and models, then read up on the MVC pattern and work out how your domain objects fit into it. Looking at the above example, I can see maybe a MathController with an add() action/method.

There are a few starting point projects for RESTful APIs on GitHub that are worth a look.

Just to addon if someone is dealing with  , this would work if dealing with  .

Replace it with str_replace() first and check it with empty()

empty(str_replace(" " ,"" , $YOUR_DATA)) ? $YOUR_DATA = '--' : $YOUR_DATA;

It will redirects to index.html on localhost:8080 call.

app.get('/',function(req,res){
    res.sendFile('index.html', { root: __dirname });
});

I describe here a problem that I faced when run npm install - the package does not appear in node_modules.

The issue was that the name value in package.json of installed package was different than the name of imported package (key in package.json of my project).

So if your installed project name is some-package (name value in its package.json) then in package.json of your project write: "some-package": "owner/some-repo#tag".

${word:$(expr index "$word" "="):1}

that gets the 7. Assuming you mean the entire rest of the string, just leave off the :1.

In the project level build.gradle file, I have replaced this line

classpath 'com.android.tools.build:gradle:3.6.3'

with this one

classpath 'com.google.gms:google-services:4.3.3'

After adding both of those lines, and syncing, everything became fine. Hope this will help someone.

This is an excellent example for understanding event bubbling concept. Based on the above answers, the final code will look like as mentioned below. Where the user Clicks on checkbox the event propagation to its parent element 'header' will be stopped using event.stopPropagation();.

$(document).ready(function() {
            $('#container').addClass('hidden');
            $('#header').click(function() {
                if($('#container').hasClass('hidden')) {
                    $('#container').removeClass('hidden');
                } else {
                    $('#container').addClass('hidden');
                }
            });
          $('#header input[type=checkbox]').click(function(event) {
              if (event.stopPropagation) {    // standard
                   event.stopPropagation();
               } else {    // IE6-8
                    event.cancelBubble = true;
               }

I dislike "Don't" answers, but... don't.

make's variables are global and are supposed to be evaluated during makefile's "parsing" stage, not during execution stage.

In this case, as long as the variable local to a single target, follow @nobar's answer and make it a shell variable.

Target-specific variables, too, are considered harmful by other make implementations: kati, Mozilla pymake. Because of them, a target can be built differently depending on if it's built standalone, or as a dependency of a parent target with a target-specific variable. And you won't know which way it was, because you don't know what is already built.

If you need to search for all element's positions between certain indices, you can state them:

[i for i,x in enumerate([1,2,3,2]) if x==2 & 2<= i <=3] # -> [3]

There are many answers here but no answer helps to manipulate the css of :before or :after , not even the accepted one.

Here is how I propose to do it. Lets suppose your HTML is like this:

<div id="something">Test</div>

And then you are setting its :before in CSS and designing it like:

#something:before{
   content:"1st";
   font-size:20px;
   color:red;
}
#something{
  content:'1st';
}

Please notice I also set content attribute in element itself so that you can take it out easily later. Now there is a button clicking on which, you want to change the color of :before to green and its font-size to 30px. You can achieve that as follows:

Define a css with your required style on some class .activeS :

.activeS:before{
   color:green !important;
   font-size:30px !important;
 }

Now you can change :before style by adding the class to your :before element as follows:

<button id="changeBefore">Change</button>
<script>
    $('#changeBefore').click(function(){
        $('#something').addClass('activeS');
    });
</script>

If you just want to get content of :before, it can be done as:

<button id="getContent">Get Content</button>
<script>
    $('#getContent').click(function(){
        console.log($('#something').css('content'));//will print '1st'
    });
</script>

Ultimately if you want to dynamically change :before content by jQuery, You can achieve that as follows:

<button id="changeBefore">Change</button>
<script>
    var newValue = '22';//coming from somewhere
    var add = '<style>#something:before{content:"'+newValue+'"!important;}</style>';
    $('#changeBefore').click(function(){
        $('body').append(add);
    });
</script>

Clicking on above "changeBefore" button will change :before content of #something into '22' which is a dynamic value.

I hope it helps

You first have to tell Gnuplot to use a style that uses points, e.g. with points or with linespoints. Try for example:

plot sin(x) with points

Output:

Now try:

plot sin(x) with points pointtype 5

Output:

You may also want to look at the output from the test command which shows you the capabilities of the current terminal. Here are the capabilities for my pngairo terminal:

To use Enum with any type of value, try this:
Updated with some improvements... Thanks @Jeff, by your tip!

from enum import Enum

class Color(Enum):
    RED = 1
    GREEN = 'GREEN'
    BLUE = ('blue', '#0000ff')

    @staticmethod
    def list():
        return list(map(lambda c: c.value, Color))

print(Color.list())

As result:

[1, 'GREEN', ('blue', '#0000ff')]

So based on what you said, these files are libraries/documentation you don't want to delete but also don't want to push to github. Let say you have your project in folder your_project and a doc directory: your_project/doc.

1. Remove it from the project directory (without actually deleting it): git rm --cached doc/*
2. If you don't already have a .gitignore, you can make one right inside of your project folder: project/.gitignore.
3. Put doc/* in the .gitignore
4. Stage the file to commit: git add project/.gitignore
5. Commit: git commit -m "message".
6. Push your change to github.

Another way

_details.Sort((s1, s2) => s1.CompareTo(s2)); 

you need to put font-awesome file in css folder and change

href="../css/font-awesome.css" to href="css/font-awesome.css"

One more thing You can Replace this Font-awesome css File And and try this one

.social-media{
  list-style-type: none;
  padding: 0px;
  margin: 0px;
}

.social-media li .fa{ 
  background: #fff;
  color: #262626;
  width: 50px;
  height: 50px;
  border-radius: 50%;
  text-align:center;
  line-height:50px; 
}

.social-media .fa:hover { 
  box-shadow: 5px 5px 5px #000; 
}

.social-media .fa.fa-twitter:hover{
  background:#55acee;
  color:#fff;
 
}

.social-media .fa.fa-facebook:hover{
  background:#3b5998;
  color:#fff;
}

<link href="https://maxcdn.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css" rel="stylesheet">

<ul class="social-media">
  <li><i class="fa fa-twitter fa-2x"></i></li>

</ul>

Turns out that the post (or rather the whole table) was locked by the very same connection that I tried to update the post with.

I had a opened record set of the post that was created by:

Set RecSet = Conn.Execute()

This type of recordset is supposed to be read-only and when I was using MS Access as database it did not lock anything. But apparently this type of record set did lock something on MS SQL Server 2012 because when I added these lines of code before executing the UPDATE SQL statement...

RecSet.Close
Set RecSet = Nothing

...everything worked just fine.

So bottom line is to be careful with opened record sets - even if they are read-only they could lock your table from updates.

The condition below:

//Element[@attribute1="abc" and @attribute2="xyz" and Data]

checks for the existence of the element Data within Element and not for element value Data.

Instead you can use

//Element[@attribute1="abc" and @attribute2="xyz" and text()="Data"]

$destroy can refer to 2 things: method and event

1. method - $scope.$destroy

.directive("colorTag", function(){
  return {
    restrict: "A",
    scope: {
      value: "=colorTag"
    },
    link: function (scope, element, attrs) {
      var colors = new App.Colors();
      element.css("background-color", stringToColor(scope.value));
      element.css("color", contrastColor(scope.value));

      // Destroy scope, because it's no longer needed.
      scope.$destroy();
    }
  };
})

2. event - $scope.$on("$destroy")

See @SunnyShah's answer.

Also for anyone using properties such as Props or Refs without your "DocgetId's" then you can:

("" as HTMLInputElement).value;

Where the inverted quotes is your props value so an example would be like so:

var val = (this.refs.newText as HTMLInputElement).value;
alert("Saving this:" + val);

to make UITableView sections header not sticky or sticky:

1. change the table view's style - make it grouped for not sticky & make it plain for sticky section headers - do not forget: you can do it from storyboard without writing code. (click on your table view and change it is style from the right Side/ component menu)

2. if you have extra components such as custom views or etc. please check the table view's margins to create appropriate design. (such as height of header for sections & height of cell at index path, sections)

Try this, just an example:

u.UserTypeOptions = new SelectList(new[]
    {
        new { ID="1", Name="name1" },
        new { ID="2", Name="name2" },
        new { ID="3", Name="name3" },
    }, "ID", "Name", 1);

Or

u.UserTypeOptions = new SelectList(new List<SelectListItem>
    {
        new SelectListItem { Selected = true, Text = string.Empty, Value = "-1"},
        new SelectListItem { Selected = false, Text = "Homeowner", Value = "2"},
        new SelectListItem { Selected = false, Text = "Contractor", Value = "3"},
    },"Value","Text");

following Anton's solution, come up with this ViewHolder which holds/handles/delegates different type of layouts. But not sure if the replacing new layout would work when the recycling view's ViewHolder is not type of the data roll in.

So basically, onCreateViewHolder(ViewGroup parent, int viewType) is only called when new view layout is needed;

getItemViewType(int position) will be called for the viewType;

onBindViewHolder(ViewHolder holder, int position) is always called when recycling the view (new data is brought in and try to display with that ViewHolder).

So when onBindViewHolder is called it needs to put in the right view layout and update the ViewHolder.

Is the way correct to replacing the view layout for that ViewHolder to be brought in, or any problem? Appreciate any comment!

public int getItemViewType(int position) {
    TypedData data = mDataSource.get(position);
    return data.type;
}

public ViewHolder onCreateViewHolder(ViewGroup parent, 
    int viewType) {
    return ViewHolder.makeViewHolder(parent, viewType);
}

public void onBindViewHolder(ViewHolder holder, 
    int position) {
    TypedData data = mDataSource.get(position);
    holder.updateData(data);

Edit: ViewHolder has member mItemViewType to hold the view

Edit: looks like in onBindViewHolder(ViewHolder holder, int position) the ViewHolder passed in has been picked up (or created) by looked at getItemViewType(int position) to make sure it is a match, so may not need to worry there that ViewHolder's type does not match the data[position]'s type. Does anyone knows more how the ViewHolder in the onBindViewHolder() is picked up?

Edit: Looks like The recycle ViewHolder is picked by type, so no warrior there.

Edit: http://wiresareobsolete.com/2014/09/building-a-recyclerview-layoutmanager-part-1/ answers this question.

It gets the recycle ViewHolder like:

holder = getRecycledViewPool().getRecycledView(mAdapter.getItemViewType(offsetPosition));

or create new one if not find recycle ViewHolder of right type.

public ViewHolder getRecycledView(int viewType) {
        final ArrayList<ViewHolder> scrapHeap = mScrap.get(viewType);
        if (scrapHeap != null && !scrapHeap.isEmpty()) {
            final int index = scrapHeap.size() - 1;
            final ViewHolder scrap = scrapHeap.get(index);
            scrapHeap.remove(index);
            return scrap;
        }
        return null;
    }

In case if you are using node js, then this could be the possible solution

const express = require("express");
const app = express();
const server = app.listen(8080);
server.keepAliveTimeout = 61 * 1000;

Your formula is wrong. You probably meant something like:

=IF(AND(NOT(ISBLANK(Q2));NOT(ISBLANK(R2)));IF(Q2<=R2;"1";"0");"")

Another equivalent:

=IF(NOT(OR(ISBLANK(Q2);ISBLANK(R2)));IF(Q2<=R2;"1";"0");"")

Or even shorter:

=IF(OR(ISBLANK(Q2);ISBLANK(R2));"";IF(Q2<=R2;"1";"0"))

OR EVEN SHORTER:

=IF(OR(ISBLANK(Q2);ISBLANK(R2));"";--(Q2<=R2))

You could call an mWebView.reload(); That's what it does

You can either:

pre { white-space: normal; }

to maintain the monospace font but add word-wrap, or:

pre { overflow: auto; }

which will allow a fixed size with horizontal scrolling for long lines.

Use DefinePlugin.

The DefinePlugin allows you to create global constants which can be configured at compile time.

new webpack.DefinePlugin(definitions)

Example:

plugins: [

Usage:

console.log(`Environment is in production: ${PRODUCTION}`);

You can send any signal to any process using the kill(2) interface:

kill -SIGABRT 30823

30823 was a dash process I started, so I could easily find the process I wanted to kill.

$ /bin/dash
$ Aborted

The Aborted output is apparently how dash reports a SIGABRT.

It can be sent directly to any process using kill(2), or a process can send the signal to itself via assert(3), abort(3), or raise(3).

The ZingChart library has an AngularJS directive that was built in-house. Features include:

• Full access to the entire ZingChart library (all charts, maps, and features)
• Takes advantage of Angular's 2-way data binding, making data and chart elements easy to update

• Support from the development team

  ...
  $scope.myJson = {
  type : 'line',
     series : [
        { values : [54,23,34,23,43] },{ values : [10,15,16,20,40] }
     ]
  };
  ...
  
  <zingchart id="myChart" zc-json="myJson" zc-height=500 zc-width=600></zingchart>
  

There is a full demo with code examples available.

As a Javascript beginner, I found Rapahel samples not so easy, I recommend http://cancerbero.mbarreneche.com/raphaeltut, which is a real Step by step tutorial.

Try this. It will work. jquery unload method is depreceted.

window.onbeforeunload = function(event) {
    event.returnValue = "Write something clever here..";
};

Oracle Client version 11 cannot connect to 8i databases. You will need a client in version 10 at most.

In your template, you have access to all the variables that are members of the current $scope. So, tobedone should be $scope.tobedone, and then you can display it with {{tobedone}}, or [[tobedone]] in your case.

Embed code example:

<object type="application/pdf" data="example.pdf" width="100%" height="100%" id="examplePDF" name="examplePDF"><param name='src' value='example.pdf'/></object>

<script>
   examplePDF.printWithDialog();
</script>

May have to fool around with the ids/names. Using adobe reader...

Instead of dropping the backup table, just rename it...

BEGIN TRANSACTION;
CREATE TABLE t1_backup(a,b);
INSERT INTO t1_backup SELECT a,b FROM t1;
DROP TABLE t1;
ALTER TABLE t1_backup RENAME TO t1;
COMMIT;

To get a new line inside text-area, put an actual line-break there:

    <textarea cols='60' rows='8'>This is my statement one._x000D_
    This is my statement2</textarea>

ul {
margin:0;
list-style-type: none;
}
li:before { content: "- ";}

Sometimes the file is kept in tracking history, try the following steps:

1. git commit, If you are seeing create mode with the big file listed, then do:

2. git filter-branch --index-filter 'git rm -r --cached --ignore-unmatch filename' HEAD. You should see a bunch of Rewrites shown in your console which ends with:

   rm 'filename' and

   the last line Ref was rewritten.

It's done.

You can access you website using your IP address and your cPanel username with ~ symbols. For Example: http://serverip/~cpusername like as https://xxx.xxx.xx.xx/~mohidul

Try this.

public class WebApiConfig
{
    public static void Register(HttpConfiguration config)
    {
        // Web API configuration and services

        var json = config.Formatters.JsonFormatter;
        json.SupportedMediaTypes.Add(new System.Net.Http.Headers.MediaTypeHeaderValue("application/json"));
        config.Formatters.Remove(config.Formatters.XmlFormatter);

        // Web API routes
        config.MapHttpAttributeRoutes();

        config.Routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: "api/{controller}/{action}/{id}",
            defaults: new { id = RouteParameter.Optional , Action =RouteParameter.Optional }

        );
    }
}

Please refer to the following link which explains why lock (this) is not a good idea.

https://docs.microsoft.com/en-us/dotnet/standard/threading/managed-threading-best-practices

So the solution is to add a private object, for example, lockObject to the class and place the code region inside the lock statement as shown below:

lock (lockObject)
{
...
}

The below code works perfectly in my case - my page contains complex java scripts

public void checkPageIsReady() {

  JavascriptExecutor js = (JavascriptExecutor)driver;


  //Initially bellow given if condition will check ready state of page.
  if (js.executeScript("return document.readyState").toString().equals("complete")){ 
   System.out.println("Page Is loaded.");
   return; 
  } 

  //This loop will rotate for 25 times to check If page Is ready after every 1 second.
  //You can replace your value with 25 If you wants to Increase or decrease wait time.
  for (int i=0; i<25; i++){ 
   try {
    Thread.sleep(1000);
    }catch (InterruptedException e) {} 
   //To check page ready state.
   if (js.executeScript("return document.readyState").toString().equals("complete")){ 
    break; 
   }   
  }
 }

General Solution

We use object-scan for a lot of data processing. It has some nice properties, especially traversing in delete safe order. Here is how one could implement find, delete and replace for your question.

// const objectScan = require('object-scan');

const tool = (() => {
  const scanner = objectScan(['[*]'], {
    abort: true,
    rtn: 'bool',
    filterFn: ({
      value, parent, property, context
    }) => {
      if (value.id === context.id) {
        context.fn({ value, parent, property });
        return true;
      }
      return false;
    }
  });
  return {
    add: (data, id, obj) => scanner(data, { id, fn: ({ parent, property }) => parent.splice(property + 1, 0, obj) }),
    del: (data, id) => scanner(data, { id, fn: ({ parent, property }) => parent.splice(property, 1) }),
    mod: (data, id, prop, v = undefined) => scanner(data, {
      id,
      fn: ({ value }) => {
        if (value !== undefined) {
          value[prop] = v;
        } else {
          delete value[prop];
        }
      }
    })
  };
})();

// -------------------------------

const data = [ { id: 'one', pId: 'foo1', cId: 'bar1' }, { id: 'three', pId: 'foo3', cId: 'bar3' } ];
const toAdd = { id: 'two', pId: 'foo2', cId: 'bar2' };

const exec = (fn) => {
  console.log('---------------');
  console.log(fn.toString());
  console.log(fn());
  console.log(data);
};

exec(() => tool.add(data, 'one', toAdd));
exec(() => tool.mod(data, 'one', 'pId', 'zzz'));
exec(() => tool.mod(data, 'one', 'other', 'test'));
exec(() => tool.mod(data, 'one', 'gone', 'delete me'));
exec(() => tool.mod(data, 'one', 'gone'));
exec(() => tool.del(data, 'three'));

// => ---------------
// => () => tool.add(data, 'one', toAdd)
// => true
// => [ { id: 'one', pId: 'foo1', cId: 'bar1' }, { id: 'two', pId: 'foo2', cId: 'bar2' }, { id: 'three', pId: 'foo3', cId: 'bar3' } ]

// => ---------------
// => () => tool.mod(data, 'one', 'other', 'test')
// => true
// => [ { id: 'one', pId: 'zzz', cId: 'bar1', other: 'test' }, { id: 'two', pId: 'foo2', cId: 'bar2' }, { id: 'three', pId: 'foo3', cId: 'bar3' } ]
// => ---------------
// => () => tool.mod(data, 'one', 'gone', 'delete me')

This is still relevant in 2018.

To String

import strings
stringFiles := strings.Join(fileSlice[:], ",")

Back to Slice again

import strings
fileSlice := strings.Split(stringFiles, ",")

The easiest and the correct way to do it - use Spacer()

Example:

Column(
    children: [
      SomeWidgetOnTheTop(),
      Spacer(),
      SomeCenterredBottomWidget(),
    ],
);

if self.automaticallyAdjustsScrollViewInsets = NO; doesn't work for you, make sure the height of either tableview header or section header is CGFLOAT_MIN not 0.

For example if you want to make tableview header 0 high, you can do:

    CGRect frame = self.tableViewHeader.frame;
    frame.size.height = CGFLOAT_MIN; //not 0
    self.tableView.tableHeaderView.frame = frame;
    self.tableView.tableHeaderView = self.tableViewHeader;

Hope it helps.

I found this an easy way of cleaning in a shape between the desired row and column. I am not sure if this is what you are looking for. Hope it helps.

            int size = sizeof(codes)/sizeof(int);
            NSMutableArray *array = [[NSMutableArray alloc] init];
            for (int i=0;i<size;++i){

            codesArray = [array copy];

    return codesArray;
}

Then I just check the error code and show alert if it is in the list

if ([[self networkErrorCodes] containsObject:[NSNumber
numberWithInt:[error code]]]){ 
// Fire Alert View Here
}

But as you can see I commented out codes that I think does not fit to my definition of NO INTERNET. E.g the code of -1012 (Authentication fail.) You may edit the list as you like.

In my project I use it at username/password entering from user. And in my view (physical) network connection errors could be the only reason to show alert view in your network based app. In any other case (e.g. incorrect username/password pair) I prefer to do some custom user friendly animation, OR just repeat the failed attempt again without any attention of the user. Especially if the user didn't explicitly initiated a network call.

Your makefile should ideally be named makefile, not make. Note that you can call your makefile anything you like, but as you found, you then need the -f option with make to specify the name of the makefile. Using the default name of makefile just makes life easier.

You need to use Arrow function ()=> ES6 feature to preserve this context within setTimeout.

// var that = this;                             // no need of this line
this.messageSuccess = true;

setTimeout(()=>{                           //<<<---using ()=> syntax
      this.messageSuccess = false;
 }, 3000);

One could achieve something similar in react native with position: absolute

let footerStyle = {
  position: 'absolute',
  bottom: 0,
}

There are a few things to keep in mind though.

1. absolute positions the element relative to its parent.
2. You might have to set the width and hight of the element manually.
3. Width and hight will change when orientation changes. This has to be managed manually

A practical style definition would look something like this:

import { Dimensions } from 'react-native';

var screenWidth = Dimensions.get('window').width; //full screen width

let footerStyle = {
  position: 'absolute',
  bottom: 0,
  width: screenWidth,
  height: 60
}

For a Windows machine start the mongod process by specifying the dbpath:

mongod --dbpath \mongodb\data

It's something you can put "(args)" after and expect it to work. A callable is usually a method or a class. Methods get called, classes get instantiated.

Josh's comments are spot on. If you are not super familiar with critical values I'd suggest playing with qt, reading the manual (?qt) in conjunction with looking at a look up table (LINK). When I first moved from SPSS to R I created a function that made critical t value look up pretty easy (I'd never use this now as it takes too much time and with the p values that are generally provided in the output it's a moot point). Here's the code for that:

critical.t <- function(){
    cat("\n","\bEnter Alpha Level","\n")
    alpha<-scan(n=1,what = double(0),quiet=T)
    cat("\n","\b1 Tailed or 2 Tailed:\nEnter either 1 or 2","\n")
    tt <- scan(n=1,what = double(0),quiet=T)
    cat("\n","\bEnter Number of Observations","\n")
    n <- scan(n=1,what = double(0),quiet=T)
    cat("\n\nCritical Value =",qt(1-(alpha/tt), n-2), "\n")
}

critical.t()

I have been implementing installation without user consent recently - it was a kiosk application for API level 21+ where I had full control over environment.

The basic requirements are

• API level 21+
• root access to install the updater as a system privileged app.

The following method reads and installs APK from InputStream:

public static boolean installPackage(Context context, InputStream in, String packageName)
            throws IOException {
        PackageInstaller packageInstaller = context.getPackageManager().getPackageInstaller();
        PackageInstaller.SessionParams params = new PackageInstaller.SessionParams(
                PackageInstaller.SessionParams.MODE_FULL_INSTALL);
        params.setAppPackageName(packageName);
        // set params
        int sessionId = packageInstaller.createSession(params);
        PackageInstaller.Session session = packageInstaller.openSession(sessionId);
        OutputStream out = session.openWrite("COSU", 0, -1);
        byte[] buffer = new byte[65536];
        int c;
        while ((c = in.read(buffer)) != -1) {
            out.write(buffer, 0, c);
        }
        session.fsync(out);
        in.close();
        out.close();

        Intent intent = new Intent(context, MainActivity.class);
        intent.putExtra("info", "somedata");  // for extra data if needed..

        Random generator = new Random();

        PendingIntent i = PendingIntent.getActivity(context, generator.nextInt(), intent,PendingIntent.FLAG_UPDATE_CURRENT);
            session.commit(i.getIntentSender());


        return true;
    }

The following code calls the installation

 try {
     InputStream is = getResources().openRawResource(R.raw.someapk_source);
                    installPackage(MainActivity.this, is, "com.example.apk");
     } catch (IOException e) {
                    Toast.makeText(MainActivity.this, e.getMessage(), Toast.LENGTH_SHORT).show();
     }

for the whole thing to work you desperately need INSTALL_PACKAGES permission, or the code above will fail silently

<uses-permission
        android:name="android.permission.INSTALL_PACKAGES" />

to get this permission you must install your APK as System application which REQUIRES root (however AFTER you have installed your updater application it seem to work WITHOUT root)

To install as system application I created a signed APK and pushed it with

adb push updater.apk /sdcard/updater.apk

and then moved it to system/priv-app - which requires remounting FS (this is why the root is required)

adb shell
su
mount -o rw,remount /system
mv /sdcard/updater.apk /system/priv-app
chmod 644 /system/priv-app/updater.apk

for some reason it didn't work with simple debug version, but logcat shows useful info if your application in priv-app is not picked up for some reason.

Take a look at the fields's proprieties (type, length, default value, etc.), they should be the same.

I had this problem with SQL Server 2008 R2 because the fields's length are not equal.

A very common usecase of calc is take 100% width and adding some margin around the element.

One can do so with:

@someMarginVariable = 15px;

margin: @someMarginVariable;
width: calc(~"100% - "@someMarginVariable*2);
width: -moz-calc(~"100% - "@someMarginVariable*2);
width: -webkit-calc(~"100% - "@someMarginVariable*2);

The fastest way to do file I/O from C# is to use the Windows ReadFile and WriteFile functions. I have written a C# class that encapsulates this capability as well as a benchmarking program that looks at differnet I/O methods, including BinaryReader and BinaryWriter. See my blog post at:

http://designingefficientsoftware.wordpress.com/2011/03/03/efficient-file-io-from-csharp/

Go to PHPMyAdmin in your browser

NOTE: You will have to do this per session.

You need to precede the lines starting with gcc and rm with a hard tab. Commands in make rules are required to start with a tab (unless they follow a semicolon on the same line). The result should look like this:

PROG = semsearch
all: $(PROG)
%: %.c
        gcc -o $@ $< -lpthread

clean:
        rm $(PROG)

Note that some editors may be configured to insert a sequence of spaces instead of a hard tab. If there are spaces at the start of these lines you'll also see the "missing separator" error. If you do have problems inserting hard tabs, use the semicolon way:

PROG = semsearch
all: $(PROG)
%: %.c ; gcc -o $@ $< -lpthread

clean: ; rm $(PROG)

With the introduction of lambda expression in Java 8 you can now have anonymous methods.

Say I have a class Alpha and I want to filter Alphas on a specific condition. To do this you can use a Predicate<Alpha>. This is a functional interface which has a method test that accepts an Alpha and returns a boolean.

Assuming that the filter method has this signature:

List<Alpha> filter(Predicate<Alpha> filterPredicate)

With the old anonymous class solution you would need to something like:

filter(new Predicate<Alpha>() {
   boolean test(Alpha alpha) {
      return alpha.centauri > 1;
   }
});

With the Java 8 lambdas you can do:

filter(alpha -> alpha.centauri > 1);

For more detailed information see the Lambda Expressions tutorial

As an update of @Live's answer, for Qt = 5.2 there is no more need to subclass QThread, as now the sleep functions are public:

Static Public Members

• QThread * currentThread()
• Qt::HANDLE currentThreadId()
• int idealThreadCount()
• void msleep(unsigned long msecs)
• void sleep(unsigned long secs)
• void usleep(unsigned long usecs)
• void yieldCurrentThread()

cf http://qt-project.org/doc/qt-5/qthread.html#static-public-members

Do this:

>>> d = [ [ None for y in range( 2 ) ] for x in range( 2 ) ]
>>> d
[[None, None], [None, None]]
>>> d[0][0] = 1
>>> d
[[1, None], [None, None]]

The other solutions will lead to this kind of problem:

>>> d = [ [ None ] * 2 ] * 2
>>> d
[[None, None], [None, None]]
>>> d[0][0] = 1
>>> d
[[1, None], [1, None]]

I had the same issue and I resolved by changing the following in web.config.

It happened to me because I am running the application using Newtonsoft.Json 4.0

From:

<dependentAssembly>
  <assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed" culture="neutral" />
  <bindingRedirect oldVersion="0.0.0.0-6.0.0.0" newVersion="6.0.0.0" />
</dependentAssembly>

To:

<dependentAssembly>
  <assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed" culture="neutral" />
  <bindingRedirect oldVersion="0.0.0.0-6.0.0.0" newVersion="4.5.0.0" />
</dependentAssembly>

With Firefox and Chrome you can use :

<a href="whatever" target="_parent" onclick="myfunction()">

If myfunction is present both in iframe and in parent, the parent one will be called.

Array in swift is written as **Array < Element > **, where Element is the type of values the array is allowed to store.

Array can be initialized as :

let emptyArray = [String]()

It shows that its an array of type string

The type of the emptyArray variable is inferred to be [String] from the type of the initializer.

For Creating the array of type string with elements

var groceryList: [String] = ["Eggs", "Milk"]

groceryList has been initialized with two items

The groceryList variable is declared as “an array of string values”, written as [String]. This particular array has specified a value type of String, it is allowed to store String values only.

There are various properities of array like :

- To check if array has elements (If array is empty or not)

isEmpty property( Boolean ) for checking whether the count property is equal to 0:

if groceryList.isEmpty {
    print("The groceryList list is empty.")
} else {
    print("The groceryList is not empty.")
}

- Appending(adding) elements in array

You can add a new item to the end of an array by calling the array’s append(_:) method:

groceryList.append("Flour")

groceryList now contains 3 items.

Alternatively, append an array of one or more compatible items with the addition assignment operator (+=):

groceryList += ["Baking Powder"]

groceryList now contains 4 items

groceryList += ["Chocolate Spread", "Cheese", "Peanut Butter"]

groceryList now contains 7 items

There is a free python tool called YouTube transcript API

You can use it in scripts or as a command line tool:

pip install youtube_transcript_api

You can reset the plot by doing this:

dev.off()

I normally configure the applicationContext using Annotation based configuration rather than XML based configuration. Anyway, I believe both of them have the same priority.

*Answering your question, system variable has higher priority *

Getting profile based beans from applicationContext

• Use @Profile on a Bean

@Component
@Profile("dev")
public class DatasourceConfigForDev

Now, the profile is dev

Note : if the Profile is given as @Profile("!dev") then the profile will exclude dev and be for all others.

• Use profiles attribute in XML

<beans profile="dev">
    <bean id="DatasourceConfigForDev" class="org.skoolguy.profiles.DatasourceConfigForDev"/>
</beans>

Set the value for profile:

• Programmatically via WebApplicationInitializer interface

  In web applications, WebApplicationInitializer can be used to configure the ServletContext programmatically

@Configuration
public class MyWebApplicationInitializer implements WebApplicationInitializer {

    @Override
    public void onStartup(ServletContext servletContext) throws ServletException {
            servletContext.setInitParameter("spring.profiles.active", "dev");
    }
}

• Programmatically via ConfigurableEnvironment

  You can also set profiles directly on the environment:

    @Autowired
    private ConfigurableEnvironment env;

    // ...

    env.setActiveProfiles("dev");

• Context Parameter in web.xml

  profiles can be activated in the web.xml of the web application as well, using a context parameter:

    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/app-config.xml</param-value>
    </context-param>
    <context-param>
        <param-name>spring.profiles.active</param-name>
        <param-value>dev</param-value>
    </context-param>

• JVM System Parameter

  The profile names passed as the parameter will be activated during application start-up:

  -Dspring.profiles.active=dev
  

  In IDEs, you can set the environment variables and values to use when an application runs. The following is the Run Configuration in Eclipse:

• Environment Variable

  to set via command line : export spring_profiles_active=dev

Any bean that does not specify a profile belongs to “default” profile.

The priority order is :

1. Context parameter in web.xml
2. WebApplicationInitializer
3. JVM System parameter
4. Environment variable

This is a two-step process:

1. you need to create a login to SQL Server for that user, based on its Windows account

   CREATE LOGIN [<domainName>\<loginName>] FROM WINDOWS;
   

2. you need to grant this login permission to access a database:

   USE (your database)
   CREATE USER (username) FOR LOGIN (your login name)
   

Once you have that user in your database, you can give it any rights you want, e.g. you could assign it the db_datareader database role to read all tables.

USE (your database)
EXEC sp_addrolemember 'db_datareader', '(your user name)'

How about creating a timer with the next date?

In your timer callback you create the timer for the following year? DateTime has always a year value. What you want to express is a recurring time specification. This is another type which you would need to create. DateTime is always represents a specific date and time but not a recurring date.

• If you want to be able to run it inside cmd.exe or batch files you need to add the directory the .exe is in to the %path% variable (System or User)
• If you want to be able to run it in the Run dialog (Win+R) or any application that calls ShellExecute, adding your exe to the app paths key is enough (This is less error prone during install/uninstall and also does not clutter up the path variable)

The difference between MyString[0] and MyString.ToCharArray()[0] is that the former treats the string as a read-only array, while ToCharArray() creates a new array. The former will be quicker (along with easier) for almost anything where it will work, but ToCharArray can be necessary if you have a method that needs to accept an array, or if you want to change the array.

If the string isn't known to be non-null and non-empty you could do:

string.IsNullOrEmpty(MyString) ? (char?)null : MyString[0]

which returns a char? of either null or the first character in the string, as appropriate.

I am on an angular project that (unfortunately) uses source code inclusion via tsconfig.json to connect different collections of code. I came across a similar StaticInjector error for a service (e.g.RestService in the top example) and I was able to fix it by listing the service dependencies in the deps array when providing the affected service in the module, for example:

import { HttpClient } from '@angular/common/http';
import { NgModule } from '@angular/core';
import { HttpModule } from '@angular/http';
import { RestService } from 'mylib/src/rest/rest.service';
...
@NgModule({
  imports: [
    ...
    HttpModule,
    ...
  ],
  providers: [
    {
      provide: RestService,
      useClass: RestService,
      deps: [HttpClient] /* the injected services in the constructor for RestService */
    },
  ]
  ...

The passwords cannot be decrypted as will makes a vulnerability for users. So, you can simply use password_verify() method to compare the passwords.

if(password_verify($upass, $userRow['user_pass'])){
     //code for redirecting to login screen }

where, $upass is password entered by user and $userRow['user_pass'] is user_pass field in database which is encrypted by password_hash() function.

Most answers use some kind of duck typing, checking for example that the object has a nodeType property. But that's not enough, because non-nodes can also have node-like properties.

The other common approach is instanceof, which can produce false positives e.g. with Object.create(Node), which is not a node despite inheriting node properties.

Moreover, both approaches above call internal essential methods, which can be problematic e.g. if the tested value is a proxy.

Instead, what I recommend is borrowing a node method and calling it on our object. The browser will check that the value is a node probably by looking at internal slots not customizable in proxies, so even they won't be able to interfere with our check.

function isNode(value) {
  try {
    Node.prototype.cloneNode.call(value, false);
    return true;
  } catch(err) {
    return false;
  }
}

You can also use property getters, if you prefer.

function isNode(value) {_x000D_
  try {_x000D_
    Object.getOwnPropertyDescriptor(Node.prototype,'nodeType').get.call(value);_x000D_
    return true;_x000D_
  } catch(err) {_x000D_
    return false;_x000D_
  }_x000D_
}

Similarly, if you want to test if a value is an element, you can use

function isElement(value) {
  try {
    Element.prototype.getAttribute.call(value, '');
    return true;
  } catch(err) {
    return false;
  }
}

function isHTMLElement(value) {
  try {
    HTMLElement.prototype.click.call(value);
    return true;
  } catch(err) {
    return false;
  }
}

Try to add auth method explicitly as below, because sometimes it is required:

session.setConfig("PreferredAuthentications", "password");

This is done with

ANALYZE TABLE table_name;

Read more about it here.

ANALYZE TABLE analyzes and stores the key distribution for a table. During the analysis, the table is locked with a read lock for MyISAM, BDB, and InnoDB. This statement works with MyISAM, BDB, InnoDB, and NDB tables.

AddSingleton()

AddSingleton() creates a single instance of the service when it is first requested and reuses that same instance in all the places where that service is needed.

AddScoped()

In a scoped service, with every HTTP request, we get a new instance. However, within the same HTTP request, if the service is required in multiple places, like in the view and in the controller, then the same instance is provided for the entire scope of that HTTP request. But every new HTTP request will get a new instance of the service.

AddTransient()

With a transient service, a new instance is provided every time a service instance is requested whether it is in the scope of the same HTTP request or across different HTTP requests.

Caller-saved registers (AKA volatile registers, or call-clobbered) are used to hold temporary quantities that need not be preserved across calls.

For that reason, it is the caller's responsibility to push these registers onto the stack or copy them somewhere else if it wants to restore this value after a procedure call.

It's normal to let a call destroy temporary values in these registers, though.

Callee-saved registers (AKA non-volatile registers, or call-preserved) are used to hold long-lived values that should be preserved across calls.

When the caller makes a procedure call, it can expect that those registers will hold the same value after the callee returns, making it the responsibility of the callee to save them and restore them before returning to the caller. Or to not touch them.

The event is probably raised before the elements are fully loaded or the references are still unset, hence the exceptions. Try only setting properties if the reference is not null and IsLoaded is true.

Basically the answer from Jani Hartikainen is right! I upvoted his answer. What was missing on my system (based on Ubuntu 15.04) was to enable PDO Extension in my php.ini

extension=pdo.so
extension=pdo_mysql.so

restart the webserver (e.g. with "sudo service apache2 restart") -> every fine :-)

To find where your current active php.ini file is located you can use phpinfo() or some other hints from here: https://www.ostraining.com/blog/coding/phpini-file/

function foo() {_x000D_
  function bar() {_x000D_
    console.trace("Tracing is Done here");_x000D_
  }_x000D_
  bar();_x000D_
}_x000D_
_x000D_
foo();

console.log(console); //to print console object_x000D_
console.clear('console.clear'); //to clear console_x000D_
console.log('console.log'); //to print log message_x000D_
console.info('console.info'); //to print log message _x000D_
console.debug('console.debug'); //to debug message_x000D_

console.table(["car", "fruits", "color"]);//to print data in table structure_x000D_
console.assert('console.assert'); //to print Error_x000D_
console.dir({"name":"test"});//to print object_x000D_
console.dirxml({"name":"test"});//to print object as xml formate

To Print Error:- console.error('x=%d', x);

console.log("This is the outer level");_x000D_
console.group();_x000D_
console.log("Level 2");_x000D_

console.warn("More of level 3");_x000D_
console.groupEnd();_x000D_
console.log("Back to level 2");_x000D_
console.groupEnd();_x000D_
console.log("Back to the outer level");

in my case I was able to find a fix and by looking at the everyone else's code it may be the same issue.. I simply just had to add 'django.contrib.sites' to the list of installed apps in the settings.py file.

hope this helps someone. this is my first contribution to the coding community

This was considered a bug in 2013: https://jira.spring.io/browse/SPR-10180

and was fixed with version 3.2.2. Problem shouldn't occur in any versions after that and your code should work just fine.

the pom.xml for the project I have doesn't have this "http://repo1.maven.org/myurlhere" anywhere in it

All projects have http://repo1.maven.org/ declared as <repository> (and <pluginRepository>) by default. This repository, which is called the central repository, is inherited like others default settings from the "Super POM" (all projects inherit from the Super POM). So a POM is actually a combination of the Super POM, any parent POMs and the current POM. This combination is called the "effective POM" and can be printed using the effective-pom goal of the Maven Help plugin (useful for debugging).

And indeed, if you run:

mvn help:effective-pom

You'll see at least the following:

  <repositories>
    <repository>
      <snapshots>
        <enabled>false</enabled>
      </snapshots>
      <id>central</id>
      <name>Maven Repository Switchboard</name>
      <url>http://repo1.maven.org/maven2</url>
    </repository>
  </repositories>
  <pluginRepositories>
    <pluginRepository>
      <releases>
        <updatePolicy>never</updatePolicy>
      </releases>
      <snapshots>
        <enabled>false</enabled>
      </snapshots>
      <id>central</id>
      <name>Maven Plugin Repository</name>
      <url>http://repo1.maven.org/maven2</url>
    </pluginRepository>
  </pluginRepositories>

it has the absolute url where the maven repo is for the project but maven is still trying to download from the general maven repo

Maven will try to find dependencies in all repositories declared, including in the central one which is there by default as we saw. But, according to the trace you are showing, you only have one repository defined (the central repository) or maven would print something like this:

Reason: Unable to download the artifact from any repository

  url.project:project:pom:x.x

from the specified remote repositories:
  central (http://repo1.maven.org/),
  another-repository (http://another/repository)

So, basically, maven is unable to find the url.project:project:pom:x.x because it is not available in central.

But without knowing which project you've checked out (it has maybe specific instructions) or which dependency is missing (it can maybe be found in another repository), it's impossible to help you further.

Possible repeated question from How to overcome the CORS issue in ReactJS

CORS works by adding new HTTP headers that allow servers to describe the set of origins that are permitted to read that information using a web browser. This must be configured in the server to allow cross domain.

You can temporary solve this issue by a chrome plugin called CORS.

I searched for git PHP implementations too, but with no results. The only way to re-create a site similar to GitHub is to setup a "real" git server on your own server and then use a PHP git web client like http://www.xiphux.com/programming/gitphp/.

Unfortunatly, you can forget to do this with a hosting solution. You need a real virtual server where you can install everything you want.

However, if you need a place where store some personal, non-public, non-accessible-to-everyone code for a project, you can try BitBucket. It offers private and private-shared git repos for free.

Self plug: I have just released a new Java HTML parser: jsoup. I mention it here because I think it will do what you are after.

Its party trick is a CSS selector syntax to find elements, e.g.:

String html = "<html><head><title>First parse</title></head>"
  + "<body><p>Parsed HTML into a doc.</p></body></html>";
Document doc = Jsoup.parse(html);
Elements links = doc.select("a");
Element head = doc.select("head").first();

See the Selector javadoc for more info.

This is a new project, so any ideas for improvement are very welcome!

SELECT Id   'PatientId',
       ISNULL(CONVERT(varchar(50),ParentId),'')  'ParentId'
FROM Patients

ISNULL always tries to return a result that has the same data type as the type of its first argument. So, if you want the result to be a string (varchar), you'd best make sure that's the type of the first argument.

COALESCE is usually a better function to use than ISNULL, since it considers all argument data types and applies appropriate precedence rules to determine the final resulting data type. Unfortunately, in this case, uniqueidentifier has higher precedence than varchar, so that doesn't help.

(It's also generally preferred because it extends to more than two arguments)

If you use PM2 via node modules instead of globally, you'll need to set interpreter: 'none' in order for the above solutions to work. Related docs here.

In ecosystem.config.js:

  apps: [
    {
      name: 'myApp',
      script: 'yarn',
      args: 'start',
      interpreter: 'none',
    },
  ],

Try the formula

=TEXT(TODAY(),"MMYYYY")

First you have to check login existence using syslogins view:

IF NOT EXISTS 
    (SELECT name  
     FROM master.sys.server_principals
     WHERE name = 'YourLoginName')
BEGIN
    CREATE LOGIN [YourLoginName] WITH PASSWORD = N'password'
END

Then you have to check your database existence:

USE your_dbname

IF NOT EXISTS
    (SELECT name
     FROM sys.database_principals
     WHERE name = 'your_dbname')
BEGIN
    CREATE USER [your_dbname] FOR LOGIN [YourLoginName] 
END

A question mark is a signifier for 'any type'. ? alone means

Any type extending Object (including Object)

while your example above means

Any type extending or implementing HasWord (including HasWord if HasWord is a non-abstract class)

Your statement is calling SELECT and WHERE but does not specify which TABLE or record set you would like to SELECT FROM.

SELECT DISTINCT Description, Date as treatmentDate
FROM (TABLE_NAME or SUBQUERY)<br> --This is missing from your query.
WHERE doothey.Patient P, doothey.Account A, doothey.AccountLine AL, doothey.Item.I
AND P.PatientID = A.PatientID
AND A.AccountNo = AL.AccountNo
AND AL.ItemNo = I.ItemNo
AND (p.FamilyName = 'Stange' AND p.GivenName = 'Jessie');

You can use urllib2 as well:

import urllib2

req = urllib2.Request('http://www.python.org/fish.html')
try:
    resp = urllib2.urlopen(req)
except urllib2.HTTPError as e:
    if e.code == 404:
        # do something...
    else:
        # ...
except urllib2.URLError as e:
    # Not an HTTP-specific error (e.g. connection refused)
    # ...
else:
    # 200
    body = resp.read()

Note that HTTPError is a subclass of URLError which stores the HTTP status code.

The ggrepel package works great for repelling overlapping text labels away from each other. You can use either geom_label_repel() (draws rectangles around the text) or geom_text_repel() functions.

In order to create an anonymous type (or any type) with a property that has a reserved keyword as its name in C#, you can prepend the property name with an at sign, @:

Html.BeginForm("Foo", "Bar", FormMethod.Post, new { @class = "myclass"})

For VB.NET this syntax would be accomplished using the dot, ., which in that language is default syntax for all anonymous types:

Html.BeginForm("Foo", "Bar", FormMethod.Post, new with { .class = "myclass" })

Free read-only viewers:

• Large Text File Viewer (Windows) – Fully customizable theming (colors, fonts, word wrap, tab size). Supports horizontal and vertical split view. Also support file following and regex search. Very fast, simple, and has small executable size.
• klogg (Windows, macOS, Linux) – A maintained fork of glogg, its main feature is regular expression search. It can also watch files, allows the user to mark lines, and has serious optimizations built in. But from a UI standpoint, it's ugly and clunky.
• LogExpert (Windows) – "A GUI replacement for tail." It's really a log file analyzer, not a large file viewer, and in one test it required 10 seconds and 700 MB of RAM to load a 250 MB file. But its killer features are the columnizer (parse logs that are in CSV, JSONL, etc. and display in a spreadsheet format) and the highlighter (show lines with certain words in certain colors). Also supports file following, tabs, multifiles, bookmarks, search, plugins, and external tools.
• Lister (Windows) – Very small and minimalist. It's one executable, barely 500 KB, but it still supports searching (with regexes), printing, a hex editor mode, and settings.
• loxx (Windows) – Supports file following, highlighting, line numbers, huge files, regex, multiple files and views, and much more. The free version can not: process regex, filter files, synchronize timestamps, and save changed files.

Free editors:

• Your regular editor or IDE. Modern editors can handle surprisingly large files. In particular, Vim (Windows, macOS, Linux), Emacs (Windows, macOS, Linux), Notepad++ (Windows), Sublime Text (Windows, macOS, Linux), and VS Code (Windows, macOS, Linux) support large (~4 GB) files, assuming you have the RAM.
• Large File Editor (Windows) – Opens and edits TB+ files, supports Unicode, uses little memory, has XML-specific features, and includes a binary mode.
• GigaEdit (Windows) – Supports searching, character statistics, and font customization. But it's buggy – with large files, it only allows overwriting characters, not inserting them; it doesn't respect LF as a line terminator, only CRLF; and it's slow.

Builtin programs (no installation required):

• less (macOS, Linux) – The traditional Unix command-line pager tool. Lets you view text files of practically any size. Can be installed on Windows, too.
• Notepad (Windows) – Decent with large files, especially with word wrap turned off.
• MORE (Windows) – This refers to the Windows MORE, not the Unix more. A console program that allows you to view a file, one screen at a time.

Web viewers:

• readfileonline.com – Another HTML5 large file viewer. Supports search.

Paid editors:

• 010 Editor (Windows, macOS, Linux) – Opens giant (as large as 50 GB) files.
• SlickEdit (Windows, macOS, Linux) – Opens large files.
• UltraEdit (Windows, macOS, Linux) – Opens files of more than 6 GB, but the configuration must be changed for this to be practical: Menu » Advanced » Configuration » File Handling » Temporary Files » Open file without temp file...
• EmEditor (Windows) – Handles very large text files nicely (officially up to 248 GB, but as much as 900 GB according to one report).
• BssEditor (Windows) – Handles large files and very long lines. Don’t require an installation. Free for non commercial use.

As Sahil Chhabra suggested you can use @JsonFormat with proper shape on your variable. In case you would like to apply it on every BigDecimal field you have in your Dto's you can override default format for given class.

@Configuration
public class JacksonObjectMapperConfiguration {

    @Autowired
    public void customize(ObjectMapper objectMapper) {
         objectMapper
            .configOverride(BigDecimal.class).setFormat(JsonFormat.Value.forShape(JsonFormat.Shape.STRING));
    }
}

The name of the spyder executable was changed to spyder3.exe in python version 3. I install pyqt5 and spyder via pip and was able to launch spyder3. I first tried without installing pyqt5 and nothing happened. Once I installed pyqt5, then spyder 3 opened.

Try the following from a windows cmd.exe prompt:

    C:\Users\..>pip install pyqt5
    C:\Users\..>pip install spyder
    C:\Users\..>spyder3

This is the question I faced in my interview.

Why is main method in Java called as public static void main(String[] args) ?

Answer:

1.main() must be declared public because it is invoked by JVM whenever the program execution starts.JVM doesnot belong to our program package.

Inorder to access main outside the package we have to declare it as public.If we declare it as anything other than public it shows a Runtime Error but not Compilation time error

2.main() must be declared as static because if a method is declared as static then we can call that method outside the class using ClassName.methodName();

class Sample
{
     static void fun()
     {
           System.out.println("Hello");       
     }
}

class Test
{
      public static void main(String[] args)
      {
                Sample.fun();
      }
}

The JVM will first Load the Test class,and will check for the Commandline arguments and calls the main method as Test.main();

3.main() must be declared as void main() because JVM is not expecting any value from main().So,it must be declared as void.

If other return type is provided,the it is a RunTimeError i.e;NoSuchMethodFoundError.

4.main() must have String arguements as arrays because JVM calls main method by passing command line arguement.As they are stored in string array object it is passed as an argument to main().

KEY is normally a synonym for INDEX. The key attribute PRIMARY KEY can also be specified as just KEY when given in a column definition. This was implemented for compatibility with other database systems.

column_definition:
      data_type [NOT NULL | NULL] [DEFAULT default_value]
      [AUTO_INCREMENT] [UNIQUE [KEY] | [PRIMARY] KEY]
      ...

Just to generate the java classes from wsdl to me the best tool is "cxf wsdl2java". Its pretty simple and easy to use. I have found some complexities with some data type in axis2. But unfortunately you can't use those client stub code in your android application because android environment doesn't allow the "java/javax" package name in compiling time unless you rename the package name.

And in the android.jar all the javax.* sources for web service consuming are not available. To resolve these I have developed this WS Client Generation Tool for android.

In background it uses "cxf wsdl2java" to generate the java client stub for android platform for you, And I have written some sources to consume the web service in a smarter way.

Just give the wsdl file location it will give you the sources and some library. you have to just put the sources and the libraries in your project. and you can just call it in some "method call fashion" just we do in our enterprise project, you don't need to know the namespace/soap action etc. For example, you have a service to login, what you need to do is :

LoginService service = new LoginService ( );
Login login = service.getLoginPort ( );
LoginServiceResponse resp = login.login ( "someUser", "somePass" );

And its fully open and free.

Sorry.Though it is a bit late but hope it would help others as well . Always use the stdClass object.e.g

 $getvidids = $ci->db->query("SELECT * FROM videogroupids WHERE videogroupid='$videogroup'   AND used='0' LIMIT 10");

foreach($getvidids->result() as $key=>$myids)
{

  $vidid[$key] = $myids->videoid;  // better methodology to retrieve and store multiple records in arrays in loop
 }

<div class="row" data-toggle="popover" data-trigger="hover" 
                 data-content="My popover content.My popover content.My popover content.My popover content.">
<div class="col-md-6">
    <label for="name">Name:</label>
    <input id="name" class="form-control" type="text" />
</div>
</div>

Basically i put the popover code in the row div, instead of the input div. Solved the problem.

You can use Eloquent in different queries and make things easier to understand and mantain:

$productCategory = ProductCategory::whereIn('category_id', ['223', '15'])
                   ->select('product_id'); //don't need ->get() or ->first()

and then we put all together:

Products::whereIn('id', $productCategory)
          ->where('active', 1)
          ->select('id', 'name', 'img', 'safe_name', 'sku', 'productstatusid')
          ->get();//runs all queries at once

This will generate the same query that you wrote in your question.

It happens to me only when modifying the XML files on the project. If you rebuild the entire project before running (Build > Rebuild Project) it doesn't show up anymore.

Old question but I came up with a definitive answer with an example. Can't hurt to keep questions fresh as I had this same problem and didn't find a clear answer. The key is to make sure you have numpy imported, and then run the isinstance bool. While this may seem simple, if you are doing some computations across different data types, this small check can serve as a quick test before your start some numpy vectorized operation.

##################
# important part!
##################

import numpy as np

####################
# toy array for demo
####################

arr = np.asarray(range(1,100,2))

########################
# The instance check
######################## 

isinstance(arr,np.ndarray)

So this is ancient, but there's a much better modern solution. Not sure what version of c#/.NET is required, but this is how I do it:

... Other method code not relevant to the question.

// a token source that will timeout at the specified interval, or if cancelled outside of this scope
using var timeoutTokenSource = new CancellationTokenSource(TimeSpan.FromSeconds(5));
using var linkedTokenSource = CancellationTokenSource.CreateLinkedTokenSource(token, timeoutTokenSource.Token);

async Task<MessageResource> FetchAsync()
{
    try
    {
        return await MessageResource.FetchAsync(m.Sid);
    } catch (TaskCanceledException e)
    {
        if (timeoutTokenSource.IsCancellationRequested)
            throw new TimeoutException("Timeout", e);
        throw;
    }
}

return await Task.Run(FetchAsync, linkedTokenSource.Token);

the CancellationTokenSource constructor takes a TimeSpan parameter which will cause that token to cancel after that interval has elapsed. You can then wrap your async (or syncronous, for that matter) code in another call to Task.Run, passing the timeout token.

This assumes you're passing in a cancellation token (the token variable). If you don't have a need to cancel the task separately from the timeout, you can just use timeoutTokenSource directly. Otherwise, you create linkedTokenSource, which will cancel if the timeout ocurrs, or if it's otherwise cancelled.

We then just catch OperationCancelledException and check which token threw the exception, and throw a TimeoutException if a timeout caused this to raise. Otherwise, we rethrow.

Also, I'm using local functions here, which were introduced in C# 7, but you could easily use lambda or actual functions to the same affect. Similarly, c# 8 introduced a simpler syntax for using statements, but those are easy enough to rewrite.

Most browsers don't fully support the numerical values for font-weight. Here's a good article about the problem, and even tough it's a little old, it does seem to be correct.

If you need something bolder then you might want to try using a different font that's bolder than your existing one. Naturally, you could probably adjust the font size for a similar effect.

It is possible to use patterns in a .gitignore file. See the gitignore man page. The pattern */target/* should ignore any directory named target and anything under it. Or you may try */target/** to ignore everything under target.

Just change

var div = '<div>top div</div>'; // you just created a text string

to

var div = document.createElement("div"); // we want a DIV element instead
div.innerHTML = "top div";

Ansible command-line help, such as ansible-playbook --help shows how to increase output verbosity by setting the verbose mode (-v) to more verbosity (-vvv) or to connection debugging verbosity (-vvvv). This should give you some of the details you're after in stdout, which you can then be logged.

There is the command line parameter --spider exactly for this. In this mode, wget does not download the files and its return value is zero if the resource was found and non-zero if it was not found. Try this (in your favorite shell):

wget -q --spider address
echo $?

Or if you want full output, leave the -q off, so just wget --spider address. -nv shows some output, but not as much as the default.
