Programs & Examples On #Screen size

You can see the resolutions for those categories in the Table 2, in this section: http://developer.android.com/guide/practices/screens_support.html#testing

Everyone can use the below mentioned android library that is the easiest way to make text sizes compatible with almost all devices screens. It actually developed on the basis of new android configuration qualifiers for screen size (introduced in Android 3.2) SmallestWidth swdp.

https://github.com/intuit/sdp

it is different for different icons.(eg, diff sizes for action bar icons, laucnher icons, etc.) please follow this link icons handbook to learn more.

Just declare a function

Size screenSize() {
return MediaQuery.of(context).size;
}

Use like below

return Container(
      width: screenSize().width,
      height: screenSize().height,
      child: ...
 )

The only thing that might make a checksum comparison slightly faster than a byte-by-byte comparison is the fact that you are reading one file at a time, somewhat reducing the seek time for the disk head. That slight gain may however very well be eaten up by the added time of calculating the hash.

Also, a checksum comparison of course only has any chance of being faster if the files are identical. If they are not, a byte-by-byte comparison would end at the first difference, making it a lot faster.

You should also consider that a hash code comparison only tells you that it's very likely that the files are identical. To be 100% certain you need to do a byte-by-byte comparison.

If the hash code for example is 32 bits, you are about 99.99999998% certain that the files are identical if the hash codes match. That is close to 100%, but if you truly need 100% certainty, that's not it.

I ran into this topic while working on input validation with read-host. If I tried to specify the data type for the variable as part of the read-host command and the user entered something other than that data type then read-host would error out. This is how I got around that and ensured that the user enters the data type I wanted:

do
    {
    try
        {
        [int]$thing = read-host -prompt "Enter a number or else"
        $GotANumber = $true
        }
    catch
        {
        $GotANumber = $false
        }
    }
until
    ($gotanumber)

Copied from MSDN:

At compile time, verbatim strings are converted to ordinary strings with all the same escape sequences. Therefore, if you view a verbatim string in the debugger watch window, you will see the escape characters that were added by the compiler, not the verbatim version from your source code. For example, the verbatim string @"C:\files.txt" will appear in the watch window as "C:\\files.txt".

I am processing a large collection of objects generated by our system; we changed the format of the stored data and needed to check each file, determine which ones were in the old format, and convert them. There are other ways to do this, but this one relates to your question.

    ObjectListing list = amazonS3Client.listObjects(contentBucketName, contentKeyPrefix);

    do {                

        List<S3ObjectSummary> summaries = list.getObjectSummaries();

        for (S3ObjectSummary summary : summaries) {

            String summaryKey = summary.getKey();               

            /* Retrieve object */

            /* Process it */

        }

        list = amazonS3Client.listNextBatchOfObjects(list);

    }while (list.isTruncated());

For client code, Promise is for observing or attaching callback when a result is available, whereas Future is to wait for result and then continue. Theoretically anything which is possible to do with futures what can done with promises, but due to the style difference, the resultant API for promises in different languages make chaining easier.

In addition to the steps outlined at this link from Orhan's answer, you may need to additionally remove the native module by going to IIS Manager > Server Root > Modules > Configure Native Modules. Select MfeEngine and then select Remove.

In the case where you don't know the locale of the string value received and it is not necessarily the same locale as the current default locale you can use this :

private static double parseDouble(String price){
    String parsedStringDouble;
    if (price.contains(",") && price.contains(".")){
        int indexOfComma = price.indexOf(",");
        int indexOfDot = price.indexOf(".");
        String beforeDigitSeparator;
        String afterDigitSeparator;
        if (indexOfComma < indexOfDot){
            String[] splittedNumber = price.split("\\.");
            beforeDigitSeparator = splittedNumber[0];
            afterDigitSeparator = splittedNumber[1];
        }
        else {
            String[] splittedNumber = price.split(",");
            beforeDigitSeparator = splittedNumber[0];
            afterDigitSeparator = splittedNumber[1];
        }
        beforeDigitSeparator = beforeDigitSeparator.replace(",", "").replace(".", "");
        parsedStringDouble = beforeDigitSeparator+"."+afterDigitSeparator;
    }
    else {
        parsedStringDouble = price.replace(",", "");
    }

    return Double.parseDouble(parsedStringDouble);

}

It will return a double no matter what the locale of the string is. And no matter how many commas or points there are. So passing 1,000,000.54 will work so will 1.000.000,54 so you don't have to rely on the default locale for parsing the string anymore. The code isn't as optimized as it can be so any suggestions are welcome. I tried to test most of the cases to make sure it solves the problem but I am not sure it covers all. If you find a breaking value let me know.

The code I'll give you works and retrieves not only keys, but a lot of data from a table in SQL Server. Is tested in SQL Server 2k5/2k8, dunno about 2k. Enjoy!

You can use only the primary key part, but I think that the rest might become handy. Best regards, David

The recommendation is was to start their name with "X-". E.g. X-Forwarded-For, X-Requested-With. This is also mentioned in a.o. section 5 of RFC 2047.

Update 1: On June 2011, the first IETF draft was posted to deprecate the recommendation of using the "X-" prefix for non-standard headers. The reason is that when non-standard headers prefixed with "X-" become standard, removing the "X-" prefix breaks backwards compatibility, forcing application protocols to support both names (E.g, x-gzip & gzip are now equivalent). So, the official recommendation is to just name them sensibly without the "X-" prefix.

Update 2: On June 2012, the deprecation of recommendation to use the "X-" prefix has become official as RFC 6648. Below are cites of relevance:

3. Recommendations for Creators of New Parameters

...

3. SHOULD NOT prefix their parameter names with "X-" or similar constructs.

4. Recommendations for Protocol Designers

...

4. SHOULD NOT prohibit parameters with an "X-" prefix or similar constructs from being registered.

5. MUST NOT stipulate that a parameter with an "X-" prefix or similar constructs needs to be understood as unstandardized.

6. MUST NOT stipulate that a parameter without an "X-" prefix or similar constructs needs to be understood as standardized.

Note that "SHOULD NOT" ("discouraged") is not the same as "MUST NOT" ("forbidden"), see also RFC 2119 for another spec on those keywords. In other words, you can keep using "X-" prefixed headers, but it's not officially recommended anymore and you may definitely not document them as if they are public standard.

Summary:

• the official recommendation is to just name them sensibly without the "X-" prefix
• you can keep using "X-" prefixed headers, but it's not officially recommended anymore and you may definitely not document them as if they are public standard

The easiest and cleanest way I've found is to use a data attribute to store your custom error. Test the node for validity and handle the error by using some custom html.

le javascript

if(node.validity.patternMismatch)
        {
            message = node.dataset.patternError;
        }

and some super HTML5

<input type="text" id="city" name="city" data-pattern-error="Please use only letters for your city." pattern="[A-z ']*" required>

you can add it in fxml. Stage level

<icons>
    <Image url="@../../../my_icon.png"/>
</icons>

I fixed mine by adding these lines on my IIS webconfig.

<httpErrors>
    <remove statusCode="405" subStatusCode="-1" />
    <error statusCode="405" prefixLanguageFilePath="" path="/my-page.htm" responseMode="ExecuteURL" />
</httpErrors>

Postgres hasn't implemented an equivalent to INSERT OR REPLACE. From the ON CONFLICT docs (emphasis mine):

It can be either DO NOTHING, or a DO UPDATE clause specifying the exact details of the UPDATE action to be performed in case of a conflict.

Though it doesn't give you shorthand for replacement, ON CONFLICT DO UPDATE applies more generally, since it lets you set new values based on preexisting data. For example:

INSERT INTO users (id, level)
VALUES (1, 0)
ON CONFLICT (id) DO UPDATE
SET level = users.level + 1;

Your web app can now take a 'native' screenshot of the client's entire desktop using getUserMedia():

Have a look at this example:

https://www.webrtc-experiment.com/Pluginfree-Screen-Sharing/

The client will have to be using chrome (for now) and will need to enable screen capture support under chrome://flags.

=VLOOKUP(LEFT(A4,LEN(A4)-9),$D:$F,3,0)

I use this if my Lookup_Value needs to be truncated because of the format the name is in the Table_Array. E.g. my Lookup_Value is "Eastbay District", but the Table_Array list I have only shows this as "Eastbay". "Eastbay District" minus 9 characters will result in "Eastbay".

I hope this helps!

ldapConnection is the server adres: ldap.example.com Ldap.Connection.Path is the path inside the ADS that you like to use insert in LDAP format.

OU=Your_OU,OU=other_ou,dc=example,dc=com

You start at the deepest OU working back to the root of the AD, then add dc=X for every domain section until you have everything including the top level domain

Now i miss a parameter to authenticate, this works the same as the path for the username

CN=username,OU=users,DC=example,DC=com

Normal answer for this question if you really want to get something like content//media/external/video/media/18576 (e.g. for your video mp4 absolute path) and not just file///storage/emulated/0/DCIM/Camera/20141219_133139.mp4:

MediaScannerConnection.scanFile(this,
          new String[] { file.getAbsolutePath() }, null,
          new MediaScannerConnection.OnScanCompletedListener() {
      public void onScanCompleted(String path, Uri uri) {
          Log.i("onScanCompleted", uri.getPath());
      }
 });

Accepted answer is wrong (cause it will not return content//media/external/video/media/*)

Uri.fromFile(file).toString() only returns something like file///storage/emulated/0/* which is a simple absolute path of a file on the sdcard but with file// prefix (scheme)

You can also get content uri using MediaStore database of Android

TEST (what returns Uri.fromFile and what returns MediaScannerConnection):

File videoFile = new File("/storage/emulated/0/video.mp4");

Log.i(TAG, Uri.fromFile(videoFile).toString());

MediaScannerConnection.scanFile(this, new String[] { videoFile.getAbsolutePath() }, null,
        (path, uri) -> Log.i(TAG, uri.toString()));

Output:

I/Test: file:///storage/emulated/0/video.mp4

I/Test: content://media/external/video/media/268927

In the pattern, the inclusion of a 'z' date-time component indicates that timezone format needs to conform to the General time zone "standard", examples of which are Pacific Standard Time; PST; GMT-08:00.

A 'Z' indicates that the timezone conforms to the RFC 822 time zone standard, e.g. -0800.

I think you need a DatatypeConverter ...

@Test
public void testTimezoneIsGreenwichMeanTime() throws ParseException {
    final Calendar calendar = javax.xml.bind.DatatypeConverter.parseDateTime("2010-04-05T17:16:00Z");
    TestCase.assertEquals("gotten timezone", "GMT+00:00", calendar.getTimeZone().getID());
}

It depends a bit on the specific filesystem in use on the Linux server. Nowadays the default is ext3 with dir_index, which makes searching large directories very fast.

So speed shouldn't be an issue, other than the one you already noted, which is that listings will take longer.

There is a limit to the total number of files in one directory. I seem to remember it definitely working up to 32000 files.

Error 127 means one of two things:

1. file not found: the path you're using is incorrect. double check that the program is actually in your $PATH, or in this case, the relative path is correct -- remember that the current working directory for a random terminal might not be the same for the IDE you're using. it might be better to just use an absolute path instead.
2. ldso is not found: you're using a pre-compiled binary and it wants an interpreter that isn't on your system. maybe you're using an x86_64 (64-bit) distro, but the prebuilt is for x86 (32-bit). you can determine whether this is the answer by opening a terminal and attempting to execute it directly. or by running file -L on /bin/sh (to get your default/native format) and on the compiler itself (to see what format it is).

if the problem is (2), then you can solve it in a few diff ways:

1. get a better binary. talk to the vendor that gave you the toolchain and ask them for one that doesn't suck.
2. see if your distro can install the multilib set of files. most x86_64 64-bit distros allow you to install x86 32-bit libraries in parallel.
3. build your own cross-compiler using something like crosstool-ng.
4. you could switch between an x86_64 & x86 install, but that seems a bit drastic ;).

You DO NOT need to upgrade Xcode.

Just open the file /usr/local/Homebrew/Library/Homebrew/extend/os/mac/diagnostic.rb ,

then remove this line check_xcode_minimum_version in the following function.

def fatal_build_from_source_checks
    %w[
      check_xcode_license_approved
      check_xcode_minimum_version //<-- this one
      check_clt_minimum_version
      check_if_xcode_needs_clt_installed
    ].freeze
    end

Then brew install should works fine.

For iOS 10.x and Swift 3.x [below versions are also supported] just add the following lines in 'info.plist'

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSAllowsArbitraryLoads</key>
    <true/>
</dict>

The Array.find method support for Microsoft's browsers started with Edge.

The W3Schools compatibility table states that the support started on version 12, while the Can I Use compatibility table says that the support was unknown between version 12 and 14, being officially supported starting at version 15.

Here's the quick fix:

If you're using capistrano do this add this to your deploy.rb:

after 'deploy:update_code' do
  run "cd #{release_path}; RAILS_ENV=production rake assets:precompile"
end

cap deploy

As other answers have mentioned, the && token in this context is new to C++0x (the next C++ standard) and represent an "rvalue reference".

Rvalue references are one of the more important new things in the upcoming standard; they enable support for 'move' semantics on objects and permit perfect forwarding of function calls.

It's a rather complex topic - one of the best introductions (that's not merely cursory) is an article by Stephan T. Lavavej, "Rvalue References: C++0x Features in VC10, Part 2"

Note that the article is still quite heavy reading, but well worthwhile. And even though it's on a Microsoft VC++ Blog, all (or nearly all) the information is applicable to any C++0x compiler.

Thanks nikie for that great Laplace suggestion. OpenCV docs pointed me in the same direction: using python, cv2 (opencv 2.4.10), and numpy...

gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY) numpy.max(cv2.convertScaleAbs(cv2.Laplacian(gray_image,3)))

result is between 0-255. I found anything over 200ish is very in focus, and by 100, it's noticeably blurry. the max never really gets much under 20 even if it's completely blurred.

To tweak a bit in order to handle the case where the variable is not set you could use a default value:

@Value("${spring.profiles.active:unknown}")
private String activeProfile;

This way if spring.profiles.active is set, it will take it else it will take the default value unknown.

So no exception will be triggered. And no need to force add something like @ActiveProfiles("test") in your test to make it pass.

I think this is the best approach. Using generic ArrayAdapter class and extends your own Object adapter is as simple as follows:

public abstract class GenericArrayAdapter<T> extends ArrayAdapter<T> {

  // Vars
  private LayoutInflater mInflater;

  public GenericArrayAdapter(Context context, ArrayList<T> objects) {
    super(context, 0, objects);
    init(context);
  }

  // Headers
  public abstract void drawText(TextView textView, T object);

  private void init(Context context) {
    this.mInflater = LayoutInflater.from(context);
  }

  @Override public View getView(int position, View convertView, ViewGroup parent) {
    final ViewHolder vh;
    if (convertView == null) {
      convertView = mInflater.inflate(android.R.layout.simple_list_item_1, parent, false);
      vh = new ViewHolder(convertView);
      convertView.setTag(vh);
    } else {
      vh = (ViewHolder) convertView.getTag();
    }

    drawText(vh.textView, getItem(position));

    return convertView;
  }

  static class ViewHolder {

    TextView textView;

    private ViewHolder(View rootView) {
      textView = (TextView) rootView.findViewById(android.R.id.text1);
    }
  }
}

and here your adapter (example):

public class SizeArrayAdapter extends GenericArrayAdapter<Size> {

  public SizeArrayAdapter(Context context, ArrayList<Size> objects) {
    super(context, objects);
  }

  @Override public void drawText(TextView textView, Size object) {
    textView.setText(object.getName());
  }

}

and finally, how to initialize it:

ArrayList<Size> sizes = getArguments().getParcelableArrayList(Constants.ARG_PRODUCT_SIZES);
SizeArrayAdapter sizeArrayAdapter = new SizeArrayAdapter(getActivity(), sizes);
listView.setAdapter(sizeArrayAdapter);

I've created a Gist with TextView layout gravity customizable ArrayAdapter:

After trying several solutions, this worked for me:

1. Go to IIS Manager
2. Open the Site
3. Click on Authentication
4. Edit Anonymous Authentication.
5. Select "Application pool identity"

example

you can add a condition to the after_update like so:

class SomeModel < ActiveRecord::Base
  after_update :send_notification, if: :published_changed?

  ...
end

there's no need to add a condition within the send_notification method itself.

Some currency pairs have no historical data for certain days.

Compare =GOOGLEFINANCE("CURRENCY:EURNOK", "close", DATE(2016,1,1), DATE(2016,1,12):

Date                Close
1/1/2016 23:58:00   9.6248922
1/2/2016 23:58:00   9.632922114
1/3/2016 23:58:00   9.579957264
1/4/2016 23:58:00   9.609146435
1/5/2016 23:58:00   9.573877808
1/6/2016 23:58:00   9.639368875
1/7/2016 23:58:00   9.707103569
1/8/2016 23:58:00   9.673324479
1/9/2016 23:58:00   9.702379872
1/10/2016 23:58:00  9.702721875
1/11/2016 23:58:00  9.705679083

and =GOOGLEFINANCE("CURRENCY:EURRUB", "close", DATE(2016,1,1), DATE(2016,1,12):

Date                Close
1/1/2016 23:58:00   79.44402768
1/4/2016 23:58:00   79.14048175
1/5/2016 23:58:00   80.0452446
1/6/2016 23:58:00   80.3761125
1/7/2016 23:58:00   81.70830185
1/8/2016 23:58:00   81.70680013
1/11/2016 23:58:00  82.50853122

So, =INDEX(GOOGLEFINANCE("CURRENCY:EURRUB", "close", DATE(2016,1,1)), 2, 2) gives

79.44402768

But =INDEX(GOOGLEFINANCE("CURRENCY:EURRUB", "close", DATE(2016,1,2)), 2, 2) gives

#N/A

Therefore, when working with currency pairs that have no exchange rates for weekends/holidays, the following formula may be used for getting the exchange rate for the first following working day:

=INDEX(GOOGLEFINANCE("CURRENCY:EURRUB", "close", DATE(2016,1,2), 4), 2, 2)

I do it as Pekka says. Put an inline style on each <li>:

Take off first and last as appropriate.

I tried to edit the answer provided by marc_s however it wasn't accepted for some reason. It formats the sql for easier reading, includes the schema and also names the Default name so that this can easily be pasted into other code.

  SELECT SchemaName = s.Name,
         TableName = t.Name,
         ColumnName = c.Name,
         DefaultName = dc.Name,
         DefaultDefinition = dc.Definition
    FROM sys.schemas                s
    JOIN sys.tables                 t   on  t.schema_id          = s.schema_id
    JOIN sys.default_constraints    dc  on  dc.parent_object_id  = t.object_id 
    JOIN sys.columns                c   on  c.object_id          = dc.parent_object_id
                                        and c.column_id          = dc.parent_column_id
ORDER BY s.Name, t.Name, c.name

Using a DateTime parameter is the best way. However, if you still want to pass a DateTime as a string, then the CAST should not be necessary provided that a language agnostic format is used.

e.g.

Given a table created like :

create table t1 (id int, EndDate DATETIME)
insert t1 (id, EndDate) values (1, GETDATE())

The following should always work :

update t1 set EndDate = '20100525' where id = 1 -- YYYYMMDD is language agnostic

The following will work :

SET LANGUAGE us_english
update t1 set EndDate = '2010-05-25' where id = 1

However, this won't :

SET LANGUAGE british
update t1 set EndDate = '2010-05-25' where id = 1  

This is because 'YYYY-MM-DD' is not a language agnostic format (from SQL server's point of view) .

The ISO 'YYYY-MM-DDThh:mm:ss' format is also language agnostic, and useful when you need to pass a non-zero time.

Just add 'unsigned' for the FOREIGN constraint

The default sqlite library that comes with iOS is not compiled using the SQLITE_THREADSAFE macro on. This could be a reason why your code crashes.

As far as I know, an input element may not have a href attribute, which is where Fancybox gets its information about the content. The following code uses an a element instead of the input element. Also, this is what I would call the "standard way".

The -m switch of PuTTY takes a path to a script file as an argument, not a command.

Reference: https://the.earth.li/~sgtatham/putty/latest/htmldoc/Chapter3.html#using-cmdline-m

So you have to save your command (command_run) to a plain text file (e.g. c:\path\command.txt) and pass that to PuTTY:

putty.exe -ssh user@host -pw password -m c:\path\command.txt

Though note that you should use Plink (a command-line connection tool from PuTTY suite). It's a console application, so you can redirect its output to a file (what you cannot do with PuTTY).

A command-line syntax is identical, an output redirection added:

plink.exe -ssh user@host -pw password -m c:\path\command.txt > output.txt

See Using the command-line connection tool Plink.

And with Plink, you can actually provide the command directly on its command-line:

plink.exe -ssh user@host -pw password command > output.txt

I had missing application context in the Tomcat Run\Debug configuration:

Adding it, solved the problem and I got the right response instead of "The origin server did not find..."

In all previous solutions, you must know the name of the attribute or field. A more generic solution for any attribute is this:

let data = 
[{
    "name": "placeHolder",
    "section": "right"
}, {
    "name": "Overview",
    "section": "left"
}, {
    "name": "ByFunction",
    "section": "left"
}, {
    "name": "Time",
    "section": "left"
}, {
    "name": "allFit",
    "section": "left"
}, {
    "name": "allbMatches",
    "section": "left"
}, {
    "name": "allOffers",
    "section": "left"
}, {
    "name": "allInterests",
    "section": "left"
}, {
    "name": "allResponses",
    "section": "left"
}, {
    "name": "divChanged",
    "section": "right"
}]    

function findByKey(key, value) {
    return (item, i) => item[key] === value
}

let findParams = findByKey('name', 'allOffers')
let index = data.findIndex(findParams)

By dictionary comprehension

d = { line.split()[0] : line.split()[1] for line in open("file.txt") }

As stated in PostgreSQL docs here:

The SQL CASE expression is a generic conditional expression, similar to if/else statements in other programming languages.

Code snippet specifically answering your question:

SELECT field1, field2,
  CASE
    WHEN field1>0 THEN field2/field1
    ELSE 0
  END 
  AS field3
FROM test

First remove old version, then run literally the following:

npm install [email protected]

and for stable or recent

npm install -g npm@latest    // For the last stable version
npm install -g npm@next      // For the most recent release

C# 3.0 :

char[] az = Enumerable.Range('a', 'z' - 'a' + 1).Select(i => (Char)i).ToArray();
foreach (var c in az)
{
    Console.WriteLine(c);
}

yes it does work even if the only overload of Enumerable.Range accepts int parameters ;-)

This is the initial database of the data source when you connect.

Edited for clarity:

If you have multiple databases in your SQL Server instance and you don't want to use the default database, you need some way to specify which one you are going to use.

all is one option:

> A <- c("A", "B", "C", "D")
> B <- A
> C <- c("A", "C", "C", "E")

> all(A==B)
[1] TRUE
> all(A==C)
[1] FALSE

But you may have to watch out for recycling:

> D <- c("A","B","A","B")
> E <- c("A","B")
> all(D==E)
[1] TRUE
> all(length(D)==length(E)) && all(D==E)
[1] FALSE

The documentation for length says it currently only outputs an integer of length 1, but that it may change in the future, so that's why I wrapped the length test in all.

    First Name: <input type="text" autocomplete="off" name="input1"/>
    <br/>
    Last Name: <input type="text" autocomplete="off" name="input2"/>
    <br/>
    <input type="submit" value="Submit" />
</form>

How do I set up the basic authorization?

All you need to do is use -u, --user USER[:PASSWORD]. Behind the scenes curl builds the Authorization header with base64 encoded credentials for you.

Example:

curl -u username:password -i -H 'Accept:application/json' http://example.com

To avoid syntax errors, be sure to always put BEGIN and END after an IF clause, eg:

IF (@A!= @SA)
   BEGIN
   --do stuff
   END
IF (@C!= @SC)
   BEGIN
   --do stuff
   END

... and so on. This should work as expected. Imagine BEGIN and END keyword as the opening and closing bracket, respectively.

If you don't need the unique identifier for further styling of the divs and are using HTML5 you could try and go with custom Data Attributes. Read on here or try a google search for HTML5 Custom Data Attributes

Basically it checks if the value before the || evaluates to true, if yes, it takes this value, if not, it takes the value after the ||.

Values for which it will take the value after the || (as far as i remember):

• undefined
• false
• 0
• '' (Null or Null string)

Delete all of them using

Step 1: Kill all containers

for i in `sudo docker ps -a | awk '{ print $1 }'`; do sudo docker kill $i ; done

Step 2: RM them first

for i in `sudo docker ps -a | awk '{ print $1 }'`; do sudo docker rm $i ; done

Step 3: Delete the images using force

for i in `sudo docker images | awk '{ print $3}'`; do  sudo docker rmi --force $i ; done

Use the step 1 in case you are getting error saying it cant be deleted owing to child dependencies

I don't think you can set that option there. You will have to use jQuery.ajax() with the appropriate parameters (basically getJSON just wraps that call into an easier API, as well).

driver.get(url) and navigate.to(url) both are used to go to particular web page. The key difference is that driver.get(url): It does not maintain the browser history and cookies and wait till page fully loaded. driver.navigate.to(url):It is also used to go to particular web page.it maintain browser history and cookies and does not wait till page fully loaded and have navigation between the pages back, forward and refresh.

It's hard to add something too such an elaborate answer. Though I feel we should mention identify here, particularly because @Ben shows a lot of dendrogram examples.

d_dist <- dist(as.matrix(d))   # find distance matrix 
plot(hclust(d_dist)) 
clusters <- identify(hclust(d_dist))

identify lets you interactively choose clusters from an dendrogram and stores your choices to a list. Hit Esc to leave interactive mode and return to R console. Note, that the list contains the indices, not the rownames (as opposed to cutree).

For all the answers using Calendar, you should use it like this instead

public static Date truncateDate(Date date) {
    Calendar c = Calendar.getInstance();
    c.setTime(date);
    c.set(Calendar.HOUR_OF_DAY, c.getActualMinimum(Calendar.HOUR_OF_DAY));
    c.set(Calendar.MINUTE, c.getActualMinimum(Calendar.MINUTE));
    c.set(Calendar.SECOND, c.getActualMinimum(Calendar.SECOND));
    c.set(Calendar.MILLISECOND, c.getActualMinimum(Calendar.MILLISECOND));
    return c.getTime();
}

But I prefer this:

public static Date truncateDate(Date date) {
    return new java.sql.Date(date.getTime());
}

A simple example using std::sort

struct MyStruct
{
    int key;
    std::string stringValue;

    MyStruct(int k, const std::string& s) : key(k), stringValue(s) {}
};

struct less_than_key
{
    inline bool operator() (const MyStruct& struct1, const MyStruct& struct2)
    {
        return (struct1.key < struct2.key);
    }
};

std::vector < MyStruct > vec;

vec.push_back(MyStruct(4, "test"));
vec.push_back(MyStruct(3, "a"));
vec.push_back(MyStruct(2, "is"));
vec.push_back(MyStruct(1, "this"));

std::sort(vec.begin(), vec.end(), less_than_key());

Edit: As Kirill V. Lyadvinsky pointed out, instead of supplying a sort predicate, you can implement the operator< for MyStruct:

struct MyStruct
{
    int key;
    std::string stringValue;

    MyStruct(int k, const std::string& s) : key(k), stringValue(s) {}

    bool operator < (const MyStruct& str) const
    {
        return (key < str.key);
    }
};

Using this method means you can simply sort the vector as follows:

std::sort(vec.begin(), vec.end());

Edit2: As Kappa suggests you can also sort the vector in the descending order by overloading a > operator and changing call of sort a bit:

struct MyStruct
{
    int key;
    std::string stringValue;

    MyStruct(int k, const std::string& s) : key(k), stringValue(s) {}

    bool operator > (const MyStruct& str) const
    {
        return (key > str.key);
    }
};

And you should call sort as:

std::sort(vec.begin(), vec.end(),greater<MyStruct>());

it does not answer the OP, but may be interesting to others: you can access the .id field in this case:

$('#drop-insert').map((i, o) => o.id)

Below illustrates XORing string s with m, and then again to reverse the process:

>>> s='hello, world'
>>> m='markmarkmark'
>>> s=''.join(chr(ord(a)^ord(b)) for a,b in zip(s,m))
>>> s
'\x05\x04\x1e\x07\x02MR\x1c\x02\x13\x1e\x0f'
>>> s=''.join(chr(ord(a)^ord(b)) for a,b in zip(s,m))
>>> s
'hello, world'
>>>

Programmatic formatting solution:

The JSON.stringify method supported by many modern browsers (including IE8) can output a beautified JSON string:

JSON.stringify(jsObj, null, "\t"); // stringify with tabs inserted at each level
JSON.stringify(jsObj, null, 4);    // stringify with 4 spaces at each level

Demo: http://jsfiddle.net/AndyE/HZPVL/

This method is also included with json2.js, for supporting older browsers.

Manual formatting solution

If you don't need to do it programmatically, Try JSON Lint. Not only will it prettify your JSON, it will validate it at the same time.

Hello I can suggest you universal method. use recursion.

    public static JSONObject function(JSONObject obj, String keyMain,String valueMain, String newValue) throws Exception {
    // We need to know keys of Jsonobject
    JSONObject json = new JSONObject()
    Iterator iterator = obj.keys();
    String key = null;
    while (iterator.hasNext()) {
        key = (String) iterator.next();
        // if object is just string we change value in key
        if ((obj.optJSONArray(key)==null) && (obj.optJSONObject(key)==null)) {
            if ((key.equals(keyMain)) && (obj.get(key).toString().equals(valueMain))) {
                // put new value
                obj.put(key, newValue);
                return obj;
            }
        }

        // if it's jsonobject
        if (obj.optJSONObject(key) != null) {
            function(obj.getJSONObject(key), keyMain, valueMain, newValue);
        }

        // if it's jsonarray
        if (obj.optJSONArray(key) != null) {
            JSONArray jArray = obj.getJSONArray(key);
            for (int i=0;i<jArray.length();i++) {
                    function(jArray.getJSONObject(i), keyMain, valueMain, newValue);
            }
        }
    }
    return obj;
}

It should work. If you have questions, go ahead.. I'm ready.

The Problem is with your code formatting,

inorder to use strtotime() You should replace '06/Oct/2011:19:00:02' with 06/10/2011 19:00:02 and date('d/M/Y:H:i:s', $date); with date('d/M/Y H:i:s', $date);. Note the spaces in between.

So the final code looks like this

$s = '06/10/2011 19:00:02';
$date = strtotime($s);
echo date('d/M/Y H:i:s', $date);

Use border-collapse:seperate; and border-spacing:0; but only use border-right and border-bottom for the tds, with border-top applied to th and border-left applied to only tr td:nth-child(1).

You can then apply border radius to the corner tds (using nth-child to find them)

https://jsfiddle.net/j4wm1f29/

tr th {
  border-top: 1px solid #000;
}

tr td:nth-child(1),
tr th:nth-child(1) {
  border-left: 1px solid #000;
}

/* border radius */
tr th:nth-child(1) {
  border-radius: 10px 0 0 0;
}

tr th:nth-last-child(1) {
  border-radius: 0 10px 0 0;
}

tr:nth-last-child(1) td:nth-child(1) {
  border-radius: 0 0 0 10px;
}

tr:nth-last-child(1) td:nth-last-child(1) {
  border-radius: 0 0 10px 0;
}

I found the following solution:

public static Double getFloatAsDouble(Float fValue) {
    return Double.valueOf(fValue.toString());
}

If you use float and double instead of Float and Double use the following:

public static double getFloatAsDouble(float value) {
    return Double.valueOf(Float.valueOf(value).toString()).doubleValue();
}

(n,) and (n,1) are not the same shape. Try casting the vector to an array by using the [:, None] notation:

n_lists = np.append(n_list_converted, n_last[:, None], axis=1)

Alternatively, when extracting n_last you can use

n_last = n_list_converted[:, -1:]

to get a (20, 1) array.

Realtime network detector - check network status without refreshing the page: (it's not jquery, but tested, and 100% works:(tested on Firefox v25.0))

Code:

<script>
 function ImgLoad(myobj){
   var randomNum = Math.round(Math.random() * 10000);
   var oImg=new Image;
   oImg.src="YOUR_IMAGELINK"+"?rand="+randomNum;
   oImg.onload=function(){alert('Image succesfully loaded!')}
   oImg.onerror=function(){alert('No network connection or image is not available.')}
}
window.onload=ImgLoad();
</script>

<button id="reloadbtn" onclick="ImgLoad();">Again!</button>

if connection lost just press the Again button.

Update 1: Auto detect without refreshing the page:

<script>
     function ImgLoad(myobj){
       var randomNum = Math.round(Math.random() * 10000);
       var oImg=new Image;
       oImg.src="YOUR_IMAGELINK"+"?rand="+randomNum;
       oImg.onload=function(){networkstatus_div.innerHTML="";}
       oImg.onerror=function(){networkstatus_div.innerHTML="Service is not available. Please check your Internet connection!";}
}

networkchecker = window.setInterval(function(){window.onload=ImgLoad()},1000);
</script>

<div id="networkstatus_div"></div>

The most simple way is..

if(window["myId"]){
    // ..
}

This is also part of HTML5 specs: https://www.w3.org/TR/html5/single-page.html#accessing-other-browsing-contexts#named-access-on-the-window-object

window[name]
    Returns the indicated element or collection of elements.

I've seen occasional problems with Eclipse forgetting that built-in classes (including Object and String) exist. The way I've resolved them is to:

• On the Project menu, turn off "Build Automatically"
• Quit and restart Eclipse
• On the Project menu, choose "Clean…" and clean all projects
• Turn "Build Automatically" back on and let it rebuild everything.

This seems to make Eclipse forget whatever incorrect cached information it had about the available classes.

I ran into this issue as well. I don't know the technical details of what was actually happening. However, in my situation, the root cause was that there was cascading deletes setup in the Oracle database and my JPA/Hibernate code was also trying to do the cascading delete calls. So my advice is to make sure that you know exactly what is happening.

You can use PreferredSize:

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Example',
      home: Scaffold(
        appBar: PreferredSize(
          preferredSize: Size.fromHeight(50.0), // here the desired height
          child: AppBar(
            // ...
          )
        ),
        body: // ...
      )
    );
  }
}

var table;

$(document).ready(function() {

    //datatables
    table = $('#userTable').DataTable({ 

        "processing": true, //Feature control the processing indicator.
        "serverSide": true, //Feature control DataTables' server-side processing mode.
        "order": [], //Initial no order.
         "aaSorting": [],

The following example creates a SqlConnection and a SqlTransaction. It also demonstrates how to use the BeginTransaction, Commit, and Rollback methods. The transaction is rolled back on any error, or if it is disposed without first being committed. Try/Catch error handling is used to handle any errors when attempting to commit or roll back the transaction.

private static void ExecuteSqlTransaction(string connectionString)
{
    using (SqlConnection connection = new SqlConnection(connectionString))
    {
        connection.Open();

        SqlCommand command = connection.CreateCommand();
        SqlTransaction transaction;

        // Start a local transaction.
        transaction = connection.BeginTransaction("SampleTransaction");

        // Must assign both transaction object and connection 
        // to Command object for a pending local transaction
        command.Connection = connection;
        command.Transaction = transaction;

        try
        {
            command.CommandText =
                "Insert into Region (RegionID, RegionDescription) VALUES (100, 'Description')";
            command.ExecuteNonQuery();
            command.CommandText =
                "Insert into Region (RegionID, RegionDescription) VALUES (101, 'Description')";
            command.ExecuteNonQuery();

            // Attempt to commit the transaction.
            transaction.Commit();
            Console.WriteLine("Both records are written to database.");
        }
        catch (Exception ex)
        {
            Console.WriteLine("Commit Exception Type: {0}", ex.GetType());
            Console.WriteLine("  Message: {0}", ex.Message);

            // Attempt to roll back the transaction. 
            try
            {
                transaction.Rollback();
            }
            catch (Exception ex2)
            {
                // This catch block will handle any errors that may have occurred 
                // on the server that would cause the rollback to fail, such as 
                // a closed connection.
                Console.WriteLine("Rollback Exception Type: {0}", ex2.GetType());
                Console.WriteLine("  Message: {0}", ex2.Message);
            }
        }
    }
}

This is the simplest way you can have your own javascript function be called when an onSubmit occurs.

HTML

<form>
    <input type="text" name="name">
    <input type="submit" name="submit">
</form>

JavaScript

window.onload = function() {
    var form = document.querySelector("form");
    form.onsubmit = submitted.bind(form);
}

function submitted(event) {
    event.preventDefault();
}

React components should have a single wrapper node or return an array of nodes.

Your <Aux>...</Aux> component has two nodes div and main.

Try to wrap your children in a div in Aux component.

import * as React from 'react';

export interface AuxProps  { 
  children: React.ReactNode
}

const aux = (props: AuxProps) => (<div>{props.children}</div>);

export default aux;

// This worked for me.
<form  name="myForm" class="css-form" novalidate ng-submit="Save(myForm.$invalid)">
<input type="text" name="uName" ng-model="User.Name" required/>
<span ng-show="User.submitted && myForm.uName.$error.required">Name is required.</span>
<input ng-click="User.submitted=true" ng-disabled="User.submitted && tForm.$invalid" type="submit" value="Save" />
</form>
// in controller
$scope.Save(invalid)
{
if(invalid) return;
// save form
}

I have created a function which will convert a csv string to an array. The function knows how to escape special characters, and it works with or without enclosure chars.

$dataArray = csvstring_to_array( file_get_contents('Address.csv'));

I tried it with your csv sample and it works as expected!

function csvstring_to_array($string, $separatorChar = ',', $enclosureChar = '"', $newlineChar = "\n") {
    // @author: Klemen Nagode
    $array = array();
    $size = strlen($string);
    $columnIndex = 0;
    $rowIndex = 0;
    $fieldValue="";
    $isEnclosured = false;
    for($i=0; $i<$size;$i++) {

        $char = $string{$i};
        $addChar = "";

        if($isEnclosured) {
            if($char==$enclosureChar) {

                if($i+1<$size && $string{$i+1}==$enclosureChar){
                    // escaped char
                    $addChar=$char;
                    $i++; // dont check next char
                }else{
                    $isEnclosured = false;
                }
            }else {
                $addChar=$char;
            }
        }else {
            if($char==$enclosureChar) {
                $isEnclosured = true;
            }else {

                if($char==$separatorChar) {

                    $array[$rowIndex][$columnIndex] = $fieldValue;
                    $fieldValue="";

                    $columnIndex++;
                }elseif($char==$newlineChar) {
                    echo $char;
                    $array[$rowIndex][$columnIndex] = $fieldValue;
                    $fieldValue="";
                    $columnIndex=0;
                    $rowIndex++;
                }else {
                    $addChar=$char;
                }
            }
        }
        if($addChar!=""){
            $fieldValue.=$addChar;

        }
    }

    if($fieldValue) { // save last field
        $array[$rowIndex][$columnIndex] = $fieldValue;
    }
    return $array;
}

Be aware that the function File.GetLastWriteTime does not always work as expected, the values are sometimes not instantaneously updated by the OS. You may get an old Timestamp, even if the file has been modified right before.

The behaviour may vary between OS versions. For example, this unit test worked well every time on my developer machine, but it always fails on our build server.

  [TestMethod]
  public void TestLastModifiedTimeStamps()
  {
     var tempFile = Path.GetTempFileName();
     var lastModified = File.GetLastWriteTime(tempFile);
     using (new FileStream(tempFile, FileMode.Create, FileAccess.Write, FileShare.None))
     {

     }
     Assert.AreNotEqual(lastModified, File.GetLastWriteTime(tempFile));
  }

See File.GetLastWriteTime seems to be returning 'out of date' value

Your options:

a) live with the occasional omissions.

b) Build up an active component realising the observer pattern (eg. a tcp server client structure), communicating the changes directly instead of writing / reading files. Fast and flexible, but another dependency and a possible point of failure (and some work, of course).

c) Ensure the signalling process by replacing the content of a dedicated signal file that other processes regularly read. It´s not that smart as it´s a polling procedure and has a greater overhead than calling File.GetLastWriteTime, but if not checking the content from too many places too often, it will do the work.

You can revert all your files under your working directory and index by typing following this command

git reset --hard <SHAsum of your commit>

You can also type

git reset --hard HEAD #your current head point

or

git reset --hard HEAD^ #your previous head point

you must to remove this item from arrayList of data

myDataset.remove(holder.getAdapterPosition());
notifyItemRemoved(holder.getAdapterPosition());
notifyItemRangeChanged(holder.getAdapterPosition(), getItemCount());

file = open("filename.txt", newline='')
for row in self.data:
    print(row)

Save data to a variable(file), so you need a with.

Try the following:

import time
timeout = time.time() + 60*5   # 5 minutes from now
while True:
    test = 0
    if test == 5 or time.time() > timeout:
        break
    test = test - 1

You may also want to add a short sleep here so this loop is not hogging CPU (for example time.sleep(1) at the beginning or end of the loop body).

See the original markdown specification (bold mine):

The implication of the “one or more consecutive lines of text” rule is that Markdown supports “hard-wrapped” text paragraphs. This differs significantly from most other text-to-HTML formatters (including Movable Type’s “Convert Line Breaks” option) which translate every line break character in a paragraph into a <br /> tag.

When you do want to insert a <br /> break tag using Markdown, you end a line with two or more spaces, then type return.

attr_accessor is a Ruby method that makes a getter and a setter. attr_accessible is a Rails method that allows you to pass in values to a mass assignment: new(attrs) or update_attributes(attrs).

Here's a mass assignment:

Order.new({ :type => 'Corn', :quantity => 6 })

You can imagine that the order might also have a discount code, say :price_off. If you don't tag :price_off as attr_accessible you stop malicious code from being able to do like so:

Order.new({ :type => 'Corn', :quantity => 6, :price_off => 30 })

Even if your form doesn't have a field for :price_off, if it's in your model it's available by default. This means a crafted POST could still set it. Using attr_accessible white lists those things that can be mass assigned.

Your textboxes are probably inside of panels or other containers, and not directly inside the form.

You need to recursively traverse the Controls collection of every child control.

{
      // the point here is to keep values quoted and avoid SQL injection
      var first = row.First.Replace("'", "''")
      var second = row.Second.Replace("'", "''")
      var third = row.Third.Replace("'", "''")

      toinsert.Add(string.Format("( '{0}', '{1}', '{2}' )", first, second, third));
}
if (toinsert.Count != 0)
{
      insertCmd.Append(string.Join(",", toinsert));
      insertCmd.Append(";");
}
using (MySqlCommand myCmd = new MySqlCommand(insertCmd.ToString(), SQLconnectionObject))
{
      myCmd.CommandType = CommandType.Text;
      myCmd.ExecuteNonQuery();
}

If you are creating an array then there is no difference, however, the following is neater:

String[] suit = {
  "spades", 
  "hearts", 
  "diamonds", 
  "clubs"  
};

But, if you want to pass an array into a method you have to call it like this:

myMethod(new String[] {"spades", "hearts"});

myMethod({"spades", "hearts"}); //won't compile!

What I do is create a vertical block for the shadow, and place it next to where my block element should be. The two blocks are then wrapped into another block:

<div id="wrapper">
    <div id="shadow"></div>  
    <div id="content">CONTENT</div>  
</div>

<style>

div#wrapper {
  width:200px;
  height:258px;      
}

div#wrapper > div#shadow {
  display:inline-block;
  width:1px;
  height:100%;
  box-shadow: -3px 0px 5px 0px rgba(0,0,0,0.8)
}

div#wrapper > div#content {
  display:inline-block;
  height:100%;
  vertical-align:top;
}

</style>

jsFiddle example here.

We can add styles function to Node prototype:

Node.prototype.styles=function(obj){ for (var k in obj)    this.style[k] = obj[k];}

Then, simply call styles method on any Node:

elem.styles({display:'block', zIndex:10, transitionDuration:'1s', left:0});

It will preserve any other existing styles and overwrite values present in the object parameter.

I was having a lot of problems to get this working, every single solution I found didn't seem to work.

I realized that I had to set the div display to flex, so basically this is my CSS:

div{
display: flex;
}

div img{ 
max-height: 100%;
max-width: 100%;
}

On Unix-like systems, dynamic linking can make life difficult for 'root' to use an application with the shared libraries installed in out-of-the-way locations. This is because the dynamic linker generally won't pay attention to LD_LIBRARY_PATH or its equivalent for processes with root privileges. Sometimes, then, static linking saves the day.

Alternatively, the installation process has to locate the libraries, but that can make it difficult for multiple versions of the software to coexist on the machine.

Because computers have finite storage capacity, automatic variables will typically be held in storage elements (whether registers or RAM) that have previously been used for some other arbitrary purpose. If a such a variable is used before a value has been assigned to it, that storage may hold whatever it held previously, and so the contents of the variable will be unpredictable.

As an additional wrinkle, many compilers may keep variables in registers which are larger than the associated types. Although a compiler would be required to ensure that any value which is written to a variable and read back will be truncated and/or sign-extended to its proper size, many compilers will perform such truncation when variables are written and expect that it will have been performed before the variable is read. On such compilers, something like:

uint16_t hey(uint32_t x, uint32_t mode)
{ uint16_t q; 
  if (mode==1) q=2; 
  if (mode==3) q=4; 
  return q; }

 uint32_t wow(uint32_t mode) {
   return hey(1234567, mode);
 }

might very well result in wow() storing the values 1234567 into registers 0 and 1, respectively, and calling foo(). Since x isn't needed within "foo", and since functions are supposed to put their return value into register 0, the compiler may allocate register 0 to q. If mode is 1 or 3, register 0 will be loaded with 2 or 4, respectively, but if it is some other value, the function may return whatever was in register 0 (i.e. the value 1234567) even though that value is not within the range of uint16_t.

To avoid requiring compilers to do extra work to ensure that uninitialized variables never seem to hold values outside their domain, and avoid needing to specify indeterminate behaviors in excessive detail, the Standard says that use of uninitialized automatic variables is Undefined Behavior. In some cases, the consequences of this may be even more surprising than a value being outside the range of its type. For example, given:

void moo(int mode)
{
  if (mode < 5)
    launch_nukes();
  hey(0, mode);      
}

a compiler could infer that because invoking moo() with a mode which is greater than 3 will inevitably lead to the program invoking Undefined Behavior, the compiler may omit any code which would only be relevant if mode is 4 or greater, such as the code which would normally prevent the launch of nukes in such cases. Note that neither the Standard, nor modern compiler philosophy, would care about the fact that the return value from "hey" is ignored--the act of trying to return it gives a compiler unlimited license to generate arbitrary code.

To reorder the rows of a DataFrame just use a list as follows.

df = df[['Mid', 'Net', 'Upper', 'Lower', 'Zsore']]

This makes it very obvious what was done when reading the code later. Also use:

df.columns
Out[1]: Index(['Net', 'Upper', 'Lower', 'Mid', 'Zsore'], dtype='object')

Then cut and paste to reorder.

For a DataFrame with many columns, store the list of columns in a variable and pop the desired column to the front of the list. Here is an example:

cols = [str(col_name) for col_name in range(1001)]
data = np.random.rand(10,1001)
df = pd.DataFrame(data=data, columns=cols)

mv_col = cols.pop(cols.index('77'))
df = df[[mv_col] + cols]

Now df.columns has.

Index(['77', '0', '1', '2', '3', '4', '5', '6', '7', '8',
       ...
       '991', '992', '993', '994', '995', '996', '997', '998', '999', '1000'],
      dtype='object', length=1001)

Using .innerText should work.

document.getElementById('lbltipAddedComment').innerText = 'your tip has been submitted!';

In Chrome, request with 'Content-Type:application/json' shows as Request PayedLoad and sends data as json object.

But request with 'Content-Type:application/x-www-form-urlencoded' shows Form Data and sends data as Key:Value Pair, so if you have array of object in one key it flats that key's value:

{ Id: 1, 
name:'john', 
phones:[{title:'home',number:111111,...},
        {title:'office',number:22222,...}]
}

sends

{ Id: 1, 
name:'john', 
phones:[object object]
phones:[object object]
}

You can create a custom loading screen instead of splash screen. if you show a splash screen for 10 sec, it's not a good idea for user experience. So it's better to add a custom loading screen. For a custom loading screen you may need some different images to make that feel like a gif. after that add the images in the res folder and make a class like this :-

public class LoadingScreen {private ImageView loading;

LoadingScreen(ImageView loading) {
    this.loading = loading;
}

public void setLoadScreen(){
    final Integer[] loadingImages = {R.mipmap.loading_1, R.mipmap.loading_2, R.mipmap.loading_3, R.mipmap.loading_4};
    final Handler loadingHandler = new Handler();
    Runnable runnable = new Runnable() {
        int loadingImgIndex = 0;
        public void run() {
            loading.setImageResource(loadingImages[loadingImgIndex]);
            loadingImgIndex++;
            if (loadingImgIndex >= loadingImages.length)
                loadingImgIndex = 0;
            loadingHandler.postDelayed(this, 500);
        }
    };
    loadingHandler.postDelayed(runnable, 500);
}}

In your MainActivity, you can pass a to the LoadingScreen class like this :-

private ImageView loadingImage;

Don't forget to add an ImageView in activity_main. After that call the LoadingScreen class like this;

LoadingScreen loadingscreen = new LoadingScreen(loadingImage);
loadingscreen.setLoadScreen();

I hope this will help you

See the documentation of Pattern.

Assuming US-ASCII alphabet (a-z, A-Z), you could use \p{Alnum}.

A regex to check that a line contains only such characters is "^[\\p{Alnum}]*$".

That also matches empty string. To exclude empty string: "^[\\p{Alnum}]+$".

Visually you can open "SQL Server Configuration Manager" and check properties of "Network Configuration":

Replace the username and password with Integrated Security=SSPI;

So the connection string should be

<connectionStrings> 
<add name="NorthwindContex" 
   connectionString="data source=localhost;
   initial catalog=northwind;persist security info=True; 
   Integrated Security=SSPI;" 
   providerName="System.Data.SqlClient" /> 
</connectionStrings> 

In my case with using Mac, I deleted /Applications/Python 3.7. because I already had Python3.7 by brew install python3 .

But it was a trigger of the message

pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.

What I did in my situation

1. I downloaded macOS 64-bit installer again, and installed.
2. Double click /Applications/Python3.6/Install Certificates.command and /Applications/Python3.6/Update Shell Profile.command.
3. Reboot mac
4. And I am not sure but possibly contributed to succeed is pip.conf. See pip install fails.

If you don't care about animation, then you don't have to get the height of the element. At least in all the browsers I've tried, if you give scrollTop a number that's bigger than the maximum, it'll just scroll to the bottom. So give it the biggest number possible:

$(myScrollingElement).scrollTop(Number.MAX_SAFE_INTEGER);

If you want to scroll the page, rather than some element with a scrollbar, just make myScrollingElement equal to 'body, html'.

Since I need to do this in several places, I've written a quick and dirty jQuery function to make it more convenient, like this:

(function($) {
  $.fn.scrollToBottom = function() {
    return this.each(function (i, element) {
      $(element).scrollTop(Number.MAX_SAFE_INTEGER);
    });
  };
}(jQuery));

So I can do this when I append a buncho' stuff:

$(myScrollingElement).append(lotsOfHtml).scrollToBottom();

There are some funnies restoring old databases into SQL 2008 via the guy; have you tried doing it via TSQL ?

Use Master

MOVE 'YourLDFLogicalName' TO 'D:\Data\YourLDFFile.ldf' 

First, which version of ubuntu are you using, it might be easiest to just upgrade to one that has it.

Next, enable backports (system menue, adminstration, software sources), and search for in in synaptic.

Last, look for a ppa for it.

I had a similar issue. Rather than run the search through the dom every time though the loop for the select control I saved the jquery select element in a variable and did this:

function isValueInSelect($select, data_value){
    return $($select).children('option').map(function(index, opt){
        return opt.value;
    }).get().includes(data_value);
}

For Ruby 2.5 or newer with transform_keys and delete_prefix / delete_suffix methods:

hash1 = { '_id' => 'random1' }
hash2 = { 'old_first' => '123456', 'old_second' => '234567' }
hash3 = { 'first_com' => 'google.com', 'second_com' => 'amazon.com' }

hash1.transform_keys { |key| key.delete_prefix('_') }
# => {"id"=>"random1"}
hash2.transform_keys { |key| key.delete_prefix('old_') }
# => {"first"=>"123456", "second"=>"234567"}
hash3.transform_keys { |key| key.delete_suffix('_com') }
# => {"first"=>"google.com", "second"=>"amazon.com"}

I'm not sure why you'd want to validate an optional email address, but I'd suggest you use

^$|^[^@\s]+@[^@\s]+$

meaning

^$        empty string
|         or
^         beginning of string
[^@\s]+   any character but @ or whitespace
@         
[^@\s]+
$         end of string

You won't stop fake emails anyway, and this way you won't stop valid addresses.

A string is a sequence of characters. So it makes sense to have an empty string, which is just an empty sequence of characters.

But DateTime is just a single value, so it's doesn't make sense to talk about an “empty” DateTime.

If you want to represent the concept of “no value”, that's represented as null in .Net. And if you want to use that with value types, you need to explicitly make them nullable. That means either using Nullable<DateTime>, or the equivalent DateTime?.

DateTime (just like all value types) also has a default value, that's assigned to uninitialized fields and you can also get it by new DateTime() or default(DateTime). But you probably don't want to use it, since it represents valid date: 1.1.0001 0:00:00.

You have to reimplement it using <xsl:choose> tag:

       <xsl:choose>

         </xsl:when>

          <h2> dooooooooooooo </h2>
         </xsl:otherwise>
       </xsl:choose>

Base on lonesomeday's answer, I create a jpost that wraps certain parameters.

$.extend({
    jpost: function(url, body) {
        return $.ajax({
            type: 'POST',
            url: url,
            data: JSON.stringify(body),
            contentType: "application/json",
            dataType: 'json'
        });
    }
});

Usage:

$.jpost('/form/', { name: 'Jonh' }).then(res => {
    console.log(res);
});

I also had problems with transformations in IE9, I used -ms-transform: rotate(10deg) and it didn't work. Tried everything I could, but the problem was in browser mode, to make transformations work, you need to set compatibility mode to "Standard IE9".

Simple, right click on your project in Android Studio, then click on the Optimize Imports that should work.

Update

To do same thing which I described above, you can do same just pressing Ctrl+Alt+O, it will optimize imports of your current file and your entire project depends on your selection in a dialog.

Here's a tidyverse version:

library(tidyverse)
data(diamonds)

(as.data.frame(table(diamonds$cut)) %>% rename(Count=1,Freq=2) %>% mutate(Perc=100*Freq/sum(Freq)))

Or if you want a handy function:

getPercentages <- function(df, colName) {
  df.cnt <- df %>% select({{colName}}) %>% 
    table() %>%
    as.data.frame() %>% 
    rename({{colName}} :=1, Freq=2) %>% 
    mutate(Perc=100*Freq/sum(Freq))
}

Now you can do:

diamonds %>% getPercentages(cut)

or this:

df=diamonds %>% group_by(cut) %>% group_modify(~.x %>% getPercentages(clarity))
ggplot(df,aes(x=clarity,y=Perc))+geom_col()+facet_wrap(~cut)

If anyone would like the answer in Swift :

var blurEffect = UIBlurEffect(style: UIBlurEffectStyle.Dark) // Change .Dark into .Light if you'd like.

var blurView = UIVisualEffectView(effect: blurEffect)

blurView.frame = theImage.bounds // 'theImage' is an image. I think you can apply this to the view too!

Update :

As of now, it's available under the IB so you don't have to code anything for it :)

Creating colnames with iterating

df = pd.DataFrame(columns=['colname_' + str(i) for i in range(5)])
print(df)

# Empty DataFrame
# Columns: [colname_0, colname_1, colname_2, colname_3, colname_4]
# Index: []

to_html() operations

print(df.to_html())

# <table border="1" class="dataframe">
#   <thead>
#     <tr style="text-align: right;">
#       <th></th>
#       <th>colname_0</th>
#       <th>colname_1</th>
#       <th>colname_2</th>
#       <th>colname_3</th>
#       <th>colname_4</th>
#     </tr>
#   </thead>
#   <tbody>
#   </tbody>
# </table>

this seems working

print(type(df.to_html()))
# <class 'str'>

The problem is caused by

when you create df like this

df = pd.DataFrame(columns=COLUMN_NAMES)

it has 0 rows × n columns, you need to create at least one row index by

df = pd.DataFrame(columns=COLUMN_NAMES, index=[0])

now it has 1 rows × n columns. You are be able to add data. Otherwise its df that only consist colnames object(like a string list).

ECMAScript 6 comes up with a new type of string literal, using the backtick as the delimiter. These literals do allow basic string interpolation expressions to be embedded, which are then automatically parsed and evaluated.

let person = {name: 'RajiniKanth', age: 68, greeting: 'Thalaivaaaa!' };

let usualHtmlStr = "<p>My name is " + person.name + ",</p>\n" +
  "<p>I am " + person.age + " old</p>\n" +
  "<strong>\"" + person.greeting + "\" is what I usually say</strong>";

let newHtmlStr =
 `<p>My name is ${person.name},</p>
  <p>I am ${person.age} old</p>
  <p>"${person.greeting}" is what I usually say</strong>`;

console.log(usualHtmlStr);
console.log(newHtmlStr);

As you can see, we used the ` around a series of characters, which are interpreted as a string literal, but any expressions of the form ${..} are parsed and evaluated inline immediately.

One really nice benefit of interpolated string literals is they are allowed to split across multiple lines:

var Actor = {"name": "RajiniKanth"};

var text =
`Now is the time for all good men like ${Actor.name}
to come to the aid of their
country!`;
console.log(text);
// Now is the time for all good men like RajiniKanth
// to come to the aid of their
// country!

Interpolated Expressions

Any valid expression is allowed to appear inside ${..} in an interpolated string literal, including function calls, inline function expression calls, and even other interpolated string literals!

function upper(s) {
  return s.toUpperCase();
}
var who = "reader"
var text =
`A very ${upper("warm")} welcome
to all of you ${upper(`${who}s`)}!`;
console.log(text);
// A very WARM welcome
// to all of you READERS!

Here, the inner `${who}s` interpolated string literal was a little bit nicer convenience for us when combining the who variable with the "s" string, as opposed to who + "s". Also to keep an note is an interpolated string literal is just lexically scoped where it appears, not dynamically scoped in any way:

function foo(str) {
  var name = "foo";
  console.log(str);
}
function bar() {
  var name = "bar";
  foo(`Hello from ${name}!`);
}
var name = "global";
bar(); // "Hello from bar!"

Using the template literal for the HTML is definitely more readable by reducing the annoyance.

The plain old way:

'<div class="' + className + '">' +
  '<p>' + content + '</p>' +
  '<a href="' + link + '">Let\'s go</a>'
'</div>';

With ECMAScript 6:

`<div class="${className}">
  <p>${content}</p>
  <a href="${link}">Let's go</a>
</div>`

• Your string can span multiple lines.
• You don't have to escape quotation characters.
• You can avoid groupings like: '">'
• You don't have to use the plus operator.

Tagged Template Literals

We can also tag a template string, when a template string is tagged, the literals and substitutions are passed to function which returns the resulting value.

function myTaggedLiteral(strings) {
  console.log(strings);
}

myTaggedLiteral`test`; //["test"]

function myTaggedLiteral(strings, value, value2) {
  console.log(strings, value, value2);
}
let someText = 'Neat';
myTaggedLiteral`test ${someText} ${2 + 3}`;
//["test", ""]
// "Neat"
// 5

We can use the spread operator here to pass multiple values. The first argument—we called it strings—is an array of all the plain strings (the stuff between any interpolated expressions).

We then gather up all subsequent arguments into an array called values using the ... gather/rest operator, though you could of course have left them as individual named parameters following the strings parameter like we did above (value1, value2, etc.).

function myTaggedLiteral(strings, ...values) {
  console.log(strings);
  console.log(values);
}

let someText = 'Neat';
myTaggedLiteral`test ${someText} ${2 + 3}`;
//["test", ""]
// "Neat"
// 5

The argument(s) gathered into our values array are the results of the already evaluated interpolation expressions found in the string literal. A tagged string literal is like a processing step after the interpolations are evaluated, but before the final string value is compiled, allowing you more control over generating the string from the literal. Let's look at an example of creating reusable templates.

const Actor = {
  name: "RajiniKanth",
  store: "Landmark"
}

const ActorTemplate = templater`<article>
  <h3>${'name'} is a Actor</h3>
  <p>You can find his movies at ${'store'}.</p>

</article>`;

function templater(strings, ...keys) {
  return function(data) {
    let temp = strings.slice();
    keys.forEach((key, i) => {
      temp[i] = temp[i] + data[key];
    });
    return temp.join('');
  }
};

const myTemplate = ActorTemplate(Actor);
console.log(myTemplate);

Raw Strings

Our tag functions receive a first argument we called strings, which is an array. But there’s an additional bit of data included: the raw unprocessed versions of all the strings. You can access those raw string values using the .raw property, like this:

function showraw(strings, ...values) {
  console.log(strings);
  console.log(strings.raw);
}
showraw`Hello\nWorld`;

As you can see, the raw version of the string preserves the escaped \n sequence, while the processed version of the string treats it like an unescaped real new-line. ECMAScript 6 comes with a built-in function that can be used as a string literal tag: String.raw(..). It simply passes through the raw versions of the strings:

console.log(`Hello\nWorld`);
/* "Hello
World" */

console.log(String.raw`Hello\nWorld`);
// "Hello\nWorld"

The query to get the nth highest record is as follows:

SELECT 
    *
FROM
    (SELECT 
        *
    FROM
        table_name
    ORDER BY column_name ASC
    LIMIT N) AS tbl
ORDER BY column_name DESC
LIMIT 1;

It's simple and easy to understand

If you HAVE to, and you don't mind a hack, you could let serialization do the work for you.

Given these classes:

public class ParentObj
{
    public string Name { get; set; }
}

public class ChildObj : ParentObj
{
    public string Value { get; set; }
}

You can create a child instance from a parent instance like so:

var parent = new ParentObj() { Name = "something" };
var serialized = JsonConvert.SerializeObject(parent);
var child = JsonConvert.DeserializeObject<ChildObj>(serialized);

This assumes your objects play nice with serialization, obv.

Be aware that this is probably going to be slower than an explicit converter.

You can use the following to get the previous URL.

var oldURL = document.referrer;
alert(oldURL);

Metrics and Svens answer deals with the usual situation but for us who work in non-english enviroments if you have exotic characters (å,ä,ö) in your character variable you will get the same result, even if you have multiple factor levels.

Levels <- c("Pri", "För") gives the contrast error, while Levels <- c("Pri", "For") doesn't

This is probably a bug.

Check the project properties. It's configurable there if you are using another .net windows application for example

Input. We will start with the text of the input shown in the question since the question did not provide the csv input:

Lines <- "Dates   Bajaj_close Hero_close
3/14/2013   1854.8  1669.1
3/15/2013   1850.3  1684.45
3/18/2013   1812.1  1690.5
3/19/2013   1835.9  1645.6

zoo. "ts" class series normally do not represent date indexes but we can create a zoo series that does (see zoo package):

library(zoo)
z <- read.zoo(text = Lines, header = TRUE, format = "%m/%d/%Y")

Alternately, if you have already read this into a data frame DF then it could be converted to zoo as shown on the second line below:

DF <- read.table(text = Lines, header = TRUE)
z <- read.zoo(DF, format = "%m/%d/%Y")

In either case above z ia a zoo series with a "Date" class time index. One could also create the zoo series, zz, which uses 1, 2, 3, ... as the time index:

zz <- z
time(zz) <- seq_along(time(zz))

ts. Either of these could be converted to a "ts" class series:

as.ts(z)
as.ts(zz)

The first has a time index which is the number of days since the Epoch (January 1, 1970) and will have NAs for missing days and the second will have 1, 2, 3, ... as the time index and no NAs.

Monthly series. Typically "ts" series are used for monthly, quarterly or yearly series. Thus if we were to aggregate the input into months we could reasonably represent it as a "ts" series:

z.m <- as.zooreg(aggregate(z, as.yearmon, mean), freq = 12)
as.ts(z.m)

To Removing all the files in folder.

import os
import glob

files = glob.glob(os.path.join('path/to/folder/*'))
files = glob.glob(os.path.join('path/to/folder/*.csv')) // It will give all csv files in folder
for file in files:
    os.remove(file)

Anyone else stumbling upon this answer should note that jQuery now (>=1.3) has outerHeight/outerWidth functions to retrieve the width including padding/borders, e.g.

$(elem).outerWidth(); // Returns the width + padding + borders

To include the margin as well, simply pass true:

$(elem).outerWidth( true ); // Returns the width + padding + borders + margins

I would think the big factor would be performance. Both the web server/app code and SQL Server would cache commonly requested data in memory and you're killing your cache performance by running them in the same memory space.

To represent the text below in JavaScript:

"'http://example.com'"

Use:

"\"'http://example.com'\""

Or:

'"\'http://example.com\'"'

Note that: We always need to escape the quote that we are surrounding the string with using \

JS Fiddle: http://jsfiddle.net/efcwG/

General Pointers:

• You can use quotes inside a string, as long as they don't match the quotes surrounding the string:

Example

var answer="It's alright";
var answer="He is called 'Johnny'";
var answer='He is called "Johnny"';

• Or you can put quotes inside a string by using the \ escape character:

Example

var answer='It\'s alright';
var answer="He is called \"Johnny\"";

• Or you can use a combination of both as shown on top.

As already mentioned, usually the comparison is done through subtraction.
For example, X86 Assembly/Control Flow.

At the hardware level there are special digital circuits for doing the calculations, like adders.

The reason is because varargs give the option of being called with a non-parametrized object array. So if your type was List < A > ... , it can also be called with List[] non-varargs type.

Here is an example:

public static void testCode(){
    List[] b = new List[1];
    test(b);
}

@SafeVarargs
public static void test(List<A>... a){
}

As you can see List[] b can contain any type of consumer, and yet this code compiles. If you use varargs, then you are fine, but if you use the method definition after type-erasure - void test(List[]) - then the compiler will not check the template parameter types. @SafeVarargs will suppress this warning.

const merge(...args)=>(new Set([].concat(...args)))

Just use UIStackView and everything will be work fine. No need to worry about other constraint, UIStackView will handle the space automatically.

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

Though both Inheritance and Composition provides code reusablility, main difference between Composition and Inheritance in Java is that Composition allows reuse of code without extending it but for Inheritance you must extend the class for any reuse of code or functionality. Another difference which comes from this fact is that by using Composition you can reuse code for even final class which is not extensible but Inheritance cannot reuse code in such cases. Also by using Composition you can reuse code from many classes as they are declared as just a member variable, but with Inheritance you can reuse code form just one class because in Java you can only extend one class, because multiple Inheritance is not supported in Java. You can do this in C++ though because there one class can extend more than one class. BTW, You should always prefer Composition over Inheritance in Java, its not just me but even Joshua Bloch has suggested in his book

Use Ajax for this.

Build a function that will fetch the current page via ajax, but not the whole page, just the div in question from the server. The data will then (again via jQuery) be put inside the same div in question and replace old content with new one.

Relevant function:

http://api.jquery.com/load/

e.g.

$('#thisdiv').load(document.URL +  ' #thisdiv');

Note, load automatically replaces content. Be sure to include a space before the id selector.

You should put the input for the last name into the same div where you have the first name.

<div>
    <label for="username">First Name</label>
    <input id="user_first_name" name="user[first_name]" size="30" type="text" />
    <input id="user_last_name" name="user[last_name]" size="30" type="text" />
</div>

Then, in your CSS give your #user_first_name and #user_last_name height and float them both to the left. For example:

#user_first_name{
    max-width:100px; /*max-width for responsiveness*/
    float:left;
}

#user_lastname_name{
    max-width:100px;
    float:left;
}

ucfagls is right, providing you use the plot() command. If not, please give us more detail.

In any case, you can control every axis seperately by using the axis() command and the xaxt/yaxt options in plot(). Using the data of ucfagls, this becomes :

plot(Y ~ X, data=foo,yaxt="n")
axis(2,cex.axis=2)

the option yaxt="n" is necessary to avoid that the plot command plots the y-axis without changing. For the x-axis, this works exactly the same :

plot(Y ~ X, data=foo,xaxt="n")
axis(1,cex.axis=2)

See also the help files ?par and ?axis

Edit : as it is for a barplot, look at the options cex.axis and cex.names :

tN <- table(sample(letters[1:5],100,replace=T,p=c(0.2,0.1,0.3,0.2,0.2)))

op <- par(mfrow=c(1,2))
barplot(tN, col=rainbow(5),cex.axis=0.5) # for the Y-axis
barplot(tN, col=rainbow(5),cex.names=0.5) # for the X-axis
par(op)

The script below is a generic solution that works for me. It is based on ideas pulled from this and other threads.

When a link with an href attribute beginning with "#" is clicked, it scrolls the page smoothly to the indicated div. Where only the "#" is present, it scrolls smoothly to the top of the page.

$('a[href^=#]').click(function(){
    event.preventDefault();
    var target = $(this).attr('href');
    if (target == '#')
      $('html, body').animate({scrollTop : 0}, 600);
    else
      $('html, body').animate({
        scrollTop: $(target).offset().top - 100
    }, 600);
});

For example, When the code above is present, clicking a link with the tag <a href="#"> scrolls to the top of the page at speed 600. Clicking a link with the tag <a href="#mydiv"> scrolls to 100px above <div id="mydiv"> at speed 600. Feel free to change these numbers.

I hope it helps!

I had this problem solved by closing Fiddler (an HTTP debugging proxy) check if you have a proxy enabled and try again.

Thanks for the ideas! I used the above ideas to make a macro to do a bulk file conversion--convert every file of one format in a folder to another format.

This code requires a sheet with cells named "FilePath" (which must end in a "\"), "StartExt" (original file extension), and "EndExt" (desired file extension). Warning: it doesn't ask for confirmation before replacing existing files with the same name and extension.

I'd like to add a little more detail to the explanation provided by everyone for the python 2 users. raw_input(), which, by now, you know that evaluates what ever data the user enters as a string. This means that python doesn't try to even understand the entered data again. All it will consider is that the entered data will be string, whether or not it is an actual string or int or anything.

While input() on the other hand tries to understand the data entered by the user. So the input like helloworld would even show the error as 'helloworld is undefined'.

In conclusion, for python 2, to enter a string too you need to enter it like 'helloworld' which is the common structure used in python to use strings.

Boost.Regex is very good and is slated to become part of the C++0x standard (it's already in TR1).

Personally, I find Boost.Xpressive much nicer to work with. It is a header-only library and it has some nice features such as static regexes (regexes compiled at compile time).

Update: If you're using a C++11 compliant compiler (gcc 4.8 is NOT!), use std::regex unless you have good reason to use something else.

As you stated, package names are usually in the form of 'com.organizationName.appName' - all lowercase and no spaces. It sounds like the package name that you entered when uploading the app was different from the one declared in the AndroidManifest.

The context parameter just sets the value of this in the iterator function.

var someOtherArray = ["name","patrick","d","w"];

_.each([1, 2, 3], function(num) { 
    // In here, "this" refers to the same Array as "someOtherArray"

    alert( this[num] ); // num is the value from the array being iterated
                        //    so this[num] gets the item at the "num" index of
                        //    someOtherArray.
}, someOtherArray);

Working Example: http://jsfiddle.net/a6Rx4/

It uses the number from each member of the Array being iterated to get the item at that index of someOtherArray, which is represented by this since we passed it as the context parameter.

If you do not set the context, then this will refer to the window object.

Try the jquery each function to walk through your json object:

$.each(data,function(i,j){
    content ='<span>'+j[i].Id+'<br />'+j[i].Name+'<br /></span>';
    $('#ProductList').append(content);
});

SimpleDateFormat has a constructor which takes the locale, have you tried that?

Something like new SimpleDateFormat("your-pattern-here", Locale.getDefault());

I've noticed that Facebook does not take thumbnails from websites if they start with https, is that maybe your case?

These steps are working on CentOS 6.5 so they should work on CentOS 7 too:

(EDIT - exactly the same steps work for MariaDB 10.3 on CentOS 8)

1. yum remove mariadb mariadb-server
2. rm -rf /var/lib/mysql If your datadir in /etc/my.cnf points to a different directory, remove that directory instead of /var/lib/mysql
3. rm /etc/my.cnf the file might have already been deleted at step 1
4. Optional step: rm ~/.my.cnf
5. yum install mariadb mariadb-server

[EDIT] - Update for MariaDB 10.1 on CentOS 7

The steps above worked for CentOS 6.5 and MariaDB 10.

I've just installed MariaDB 10.1 on CentOS 7 and some of the steps are slightly different.

Step 1 would become:

yum remove MariaDB-server MariaDB-client

Step 5 would become:

yum install MariaDB-server MariaDB-client

The other steps remain the same.

I know that are already many answers written for this solution however I want to show another javascript method (dependent on JQuery) in which you simply need to include ONLY a single JS File without any dependency on CSS or Gif Images in your code and that will take care of all progress bar related animations that happens during Ajax Request. You need to simnply pass javascript function like this

var objGlobalEvent = new RegisterGlobalEvents(true, "");

Here is the working fiddle for the code. https://jsfiddle.net/vibs2006/c7wukc41/3/

If your merge was not too complicated another option would be to:

1. Move all the changes including the merge changes back to stash using "git stash"
2. Run the merge again and commit your changes (without the changes from the dropped stash)
3. Run a "git stash pop" which should ignore all the changes from your previous merge since the files are identical now.

After that you are left with only the changes from the stash you dropped too early.

This cannot be done with pure HTML. You must rely on JavaScript for this trick.

However, if you place two forms on the HTML page you can do this.

Form1 would have the previous button.

Form2 would have any user inputs + the next button.

When the user presses Enter in Form2, the Next submit button would fire.

Here is my take: these functions convert a UTF8 string to a proper HEX without the extra zeroes padding. A real UTF8 string has characters with 1, 2, 3 and 4 bytes length.

While working on this I found a couple key things that solved my problems:

1. str.split('') doesn't handle multi-byte characters like emojis correctly. The proper/modern way to handle this is with Array.from(str)
2. encodeURIComponent() and decodeURIComponent() are great tools to convert between string and hex. They are pretty standard, they handle UTF8 correctly.
3. (Most) ASCII characters (codes 0 - 127) don't get URI encoded, so they need to handled separately. But c.charCodeAt(0).toString(16) works perfectly for those

    function utf8ToHex(str) {
      return Array.from(str).map(c => 
        c.charCodeAt(0) < 128 ? c.charCodeAt(0).toString(16) : 
        encodeURIComponent(c).replace(/\%/g,'').toLowerCase()
      ).join('');
    },
    function hexToUtf8: function(hex) {
      return decodeURIComponent('%' + hex.match(/.{1,2}/g).join('%'));
    }

This worked for for me: getResources().openRawResource(R.raw.certificate)

Use a table variable or a temporary table.

As has been mentioned before, a cursor is a last resort. Mostly because it uses lots of resources, issues locks and might be a sign you're just not understanding how to use SQL properly.

Side note: I once came across a solution that used cursors to update rows in a table. After some scrutiny, it turned out the whole thing could be replaced with a single UPDATE command. However, in this case, where a stored procedure should be executed, a single SQL-command won't work.

Create a table variable like this (if you're working with lots of data or are short on memory, use a temporary table instead):

DECLARE @menus AS TABLE (
    id INT IDENTITY(1,1),
    parent NVARCHAR(128),
    child NVARCHAR(128));

The id is important.

Replace parent and child with some good data, e.g. relevant identifiers or the whole set of data to be operated on.

Insert data in the table, e.g.:

INSERT INTO @menus (parent, child) 
  VALUES ('Some name',  'Child name');
...
INSERT INTO @menus (parent,child) 
  VALUES ('Some other name', 'Some other child name');

Declare some variables:

DECLARE @id INT = 1;
DECLARE @parentName NVARCHAR(128);
DECLARE @childName NVARCHAR(128);

And finally, create a while loop over the data in the table:

WHILE @id IS NOT NULL
BEGIN
    SELECT @parentName = parent,
           @childName = child 
        FROM @menus WHERE id = @id;

    EXEC myProcedure @parent=@parentName, @child=@childName;

    SELECT @id = MIN(id) FROM @menus WHERE id > @id;
END

The first select fetches data from the temporary table. The second select updates the @id. MIN returns null if no rows were selected.

An alternative approach is to loop while the table has rows, SELECT TOP 1 and remove the selected row from the temp table:

WHILE EXISTS(SELECT 1 FROM @menuIDs) 
BEGIN
    SELECT TOP 1 @menuID = menuID FROM @menuIDs;

    EXEC myProcedure @menuID=@menuID;

    DELETE FROM @menuIDs WHERE menuID = @menuID;
END;

simple just run

rm -r node_modules

in fact, you can delete any folder with this.

like rm -r AnyFolderWhichIsNotDeletableFromShiftDeleteOrDelete.

just open the gitbash move to root of the folder and run this command

Hope this will help.

for those who need it in Java, using apache httpcomponents 4.0:

                views = float(lst[5].replace(",", "")))

Using zsh:

a=(*(/N)); echo ${#a}

The N is a nullglob, / makes it match directories, # counts. It will neatly cope with spaces in directory names as well as returning 0 if there are no directories.

If you open the directory which it is trying to delete then also you will face same error so first close the folder.

United Kingdom Phone Formats

For the application I developed, I found that people entered their phone number 'correctly' from a human readable form, but inserted varous random characters such as '-' '/' '+44' etc. The problem was that the cloud app that it needed to talk to was quite specific about the format. Rather than use a regular expression (can be frustrating for the user) I created an object class which processes the entered number into the correct format before being processed by the persistence module.

The format of the output ensures that any receiving software interprets the output as text rather than an integer (which would then immediately lose the leading zero) and the format is consistent with British Telecoms guidelines on number formatting - which also aids human memorability by dividing a long number into small, easily memorised, groups.

+441234567890 produces (01234) 567 890
02012345678 produces (020) 1234 5678
1923123456 produces (01923) 123 456
01923123456 produces (01923) 123 456
01923hello this is text123456 produces (01923) 123 456

The significance of the exchange segment of the number - in parentheses - is that in the UK, and most other countries, calls between numbers in the same exchange can be made omitting the exchange segment. This does not apply to 07, 08 and 09 series phone numbers however.

I'm sure that there are more efficient solutions, but this one has proved extremely reliable. More formats can easily be accomodated by adding to the teleNum function at the end.

The procedure is invoked from the calling script thus

$telephone = New Telephone;
$formattedPhoneNumber = $telephone->toIntegerForm($num)

`

<?php
class   Telephone 
{   
    public function toIntegerForm($num) {
        /*
         * This section takes the number, whatever its format, and purifies it to just digits without any space or other characters
         * This ensures that the formatter only has one type of input to deal with
         */
        $number = str_replace('+44', '0', $num);
        $length = strlen($number);
        $digits = '';
        $i=0;
        while ($i<$length){
            $digits .= $this->first( substr($number,$i,1) , $i);
            $i++;
        }
        if (strlen($number)<10) {return '';}
        return $this->toTextForm($digits);
    }
    public function toTextForm($number) {

        /*
         * This works on the purified number to then format it according to the group code
         * Numbers starting 01 and 07 are grouped 5 3 3
         * Other numbers are grouped 3 4 4 
         * 
         */
        if (substr($number,0,1) == '+') { return $number; }
        $group = substr($number,0,2);
        switch ($group){
            case "02" :
                $formattedNumber = $this->teleNum($number, 3, 4); // If number commences '02N' then output will be (02N) NNNN NNNN
                break;
            default :
                $formattedNumber = $this->teleNum($number, 5, 3); // Otherwise the ooutput will be (0NNNN) NNN NNN
        }
        return $formattedNumber;

    }
    private function first($digit,$position){
        if ($digit == '+' && $position == 0) {return $digit;};
        if (!is_numeric($digit)){
            return '';
        }
        if ($position == 0) {
            return ($digit == '0' ) ? $digit :  '0'.$digit;
        } else {
            return $digit;
        } 
    }
    private function teleNum($number,$a,$b){
        /*
         * Formats the required output 
         */
        $c=strlen($number)-($a+$b);
        $bit1 = substr($number,0,$a);
        $bit2 = substr($number,$a,$b);
        $bit3 = substr($number,$a+$b,$c);
        return '('.$bit1.') '.$bit2." ".$bit3;

Given your container width 600px.

If you want only bigger images than that to fit inside, add: CSS:

#ImageContainer img {
    max-width: 600px;
}

If you want ALL images to take the avaiable (600px) space:

#ImageContainer img {
    width: 600px;
}

For me in datetimepicker jquery plugin format:'d/m/Y' option is worked

$("#dobDate").datetimepicker({

format:'d/m/Y',
onChangeDateTime:function( ct ){
   $(".xdsoft_datetimepicker").hide();
}
});

Update:

MongoServer.Create is obsolete now (thanks to @aknuds1). Instead this use following code:

var _server = new MongoClient(connectionString).GetServer();

It's easy. You should first take database name from connection string and then get database by name. Complete example:

var connectionString = "mongodb://localhost:27020/mydb";

//take database name from connection string
var _databaseName = MongoUrl.Create(connectionString).DatabaseName;
var _server = MongoServer.Create(connectionString);

//and then get database by database name:
_server.GetDatabase(_databaseName);

Important: If your database and auth database are different, you can add a authSource= query parameter to specify a different auth database. (thank you to @chrisdrobison)

From docs:

NOTE If you are using the database segment as the initial database to use, but the username and password specified are defined in a different database, you can use the authSource option to specify the database in which the credential is defined. For example, mongodb://user:pass@hostname/db1?authSource=userDb would authenticate the credential against the userDb database instead of db1.

Visual Basic has built-in constants for newlines:

vbCr = Chr$(13) = CR (carriage-return character) - used by Mac OS and Apple II family

vbLf = Chr$(10) = LF (line-feed character) - used by Linux and Mac OS X

vbCrLf = Chr$(13) & Chr$(10) = CRLF (carriage-return followed by line-feed) - used by Windows

vbNewLine = the same as vbCrLf

I would recommend that you use the jQuery plugin for Verimail.js.

Why?

• IANA TLD validation
• Syntax validation (according to RFC 822)
• Spelling suggestion for the most common TLDs and email domains
• Deny temporary email account domains such as mailinator.com

How?

Include verimail.jquery.js on your site and use the function:

$("input#email-address").verimail({
    messageElement: "p#status-message"
});

If you have a form and want to validate the email on submit, you can use the getVerimailStatus-function:

if($("input#email-address").getVerimailStatus() < 0){
    // Invalid email
}else{
    // Valid email
}

A "sort merge" join is performed by sorting the two data sets to be joined according to the join keys and then merging them together. The merge is very cheap, but the sort can be prohibitively expensive especially if the sort spills to disk. The cost of the sort can be lowered if one of the data sets can be accessed in sorted order via an index, although accessing a high proportion of blocks of a table via an index scan can also be very expensive in comparison to a full table scan.

A hash join is performed by hashing one data set into memory based on join columns and reading the other one and probing the hash table for matches. The hash join is very low cost when the hash table can be held entirely in memory, with the total cost amounting to very little more than the cost of reading the data sets. The cost rises if the hash table has to be spilled to disk in a one-pass sort, and rises considerably for a multipass sort.

(In pre-10g, outer joins from a large to a small table were problematic performance-wise, as the optimiser could not resolve the need to access the smaller table first for a hash join, but the larger table first for an outer join. Consequently hash joins were not available in this situation).

The cost of a hash join can be reduced by partitioning both tables on the join key(s). This allows the optimiser to infer that rows from a partition in one table will only find a match in a particular partition of the other table, and for tables having n partitions the hash join is executed as n independent hash joins. This has the following effects:

1. The size of each hash table is reduced, hence reducing the maximum amount of memory required and potentially removing the need for the operation to require temporary disk space.
2. For parallel query operations the amount of inter-process messaging is vastly reduced, reducing CPU usage and improving performance, as each hash join can be performed by one pair of PQ processes.
3. For non-parallel query operations the memory requirement is reduced by a factor of n, and the first rows are projected from the query earlier.

You should note that hash joins can only be used for equi-joins, but merge joins are more flexible.

In general, if you are joining large amounts of data in an equi-join then a hash join is going to be a better bet.

This topic is very well covered in the documentation.

Disclosure: I wrote FieldVal.

Here is a solution using FieldVal. By using FieldVal UI to build a form and then FieldVal to validate the input, you can pass the error straight back into the form.

You can even run the validation code on the backend (if you're using Node.js) and show the error in the form without wiring all of the fields up manually.

Live demo: http://codepen.io/MarcusLongmuir/pen/WbOydx

function validate_form(data) {
    // This would work on the back end too (if you're using Node)

    // Validate the provided data
    var validator = new FieldVal(data);
    validator.get("email", BasicVal.email(true));
    validator.get("title", BasicVal.string(true));
    validator.get("url", BasicVal.url(true));
    return validator.end();
}


$(document).ready(function(){

    // Create a form and add some fields
    var form = new FVForm()
    .add_field("email", new FVTextField("Email"))
    .add_field("title", new FVTextField("Title"))
    .add_field("url", new FVTextField("URL"))
    .on_submit(function(value){

        // Clear the existing errors
        form.clear_errors();

        // Use the function above to validate the input
        var error = validate_form(value);

        if (error) {
            // Pass the error into the form
            form.error(error);
        } else {
            // Use the data here
            alert(JSON.stringify(value));
        }
    })

    form.element.append(
        $("<button/>").text("Submit")
    ).appendTo("body");

    //Pre-populate the form
    form.val({
        "email": "[email protected]",
        "title": "Your Title",
        "url": "http://www.example.com"
    })
});

To keep the log clean as nothing happened (with some downsides with this approach (due to push -f)):

git checkout <branch>
git reset --hard <commit-hash-before-merge>
git push -f origin HEAD:<remote-branch>

'commit-hash-before-merge' comes from the log (git log) after merge.

In java there is no explicit way doing garbage collection. The JVM itself runs some threads in the background checking for the objects that are not having any references which means all the ways through which we access the object are lost. On the other hand an object is also eligible for garbage collection if it runs out of scope that is the program in which we created the object is terminated or ended. Coming to your question the method finalize is same as the destructor in C++. The finalize method is actually called just before the moment of clearing the object memory by the JVM. It is up to you to define the finalize method or not in your program. However if the garbage collection of the object is done after the program is terminated then the JVM will not invoke the finalize method which you defined in your program. You might ask what is the use of finalize method? For instance let us consider that you created an object which requires some stream to external file and you explicitly defined a finalize method to this object which checks wether the stream opened to the file or not and if not it closes the stream. Suppose, after writing several lines of code you lost the reference to the object. Then it is eligible for garbage collection. When the JVM is about to free the space of your object the JVM just checks have you defined the finalize method or not and invokes the method so there is no risk of the opened stream. finalize method make the program risk free and more robust.

this worked great:

UPDATE
    table_Name
SET 
  column_A = CASE WHEN @flag = '1' THEN column_A + @new_value ELSE column_A END,

WHERE
    ID = @ID

@NoCanDo: You cannot create an array with different data types because java only supports variables with a specific data type or object. When you are creating an array, you are pulling together an assortment of similar variables -- almost like an extended variable. All of the variables must be of the same type therefore. Java cannot differentiate the data type of your variable unless you tell it what it is. Ex: int tells all your variables declared to it are of data type int. What you could do is create 3 arrays with corresponding information.

Now, a single index number gives you all the info for that book. Ex: All of your arrays with index number 0 ([0]) have information for book 1.

Use the > command. To indent five lines, 5>>. To mark a block of lines and indent it, Vjj> to indent three lines (Vim only). To indent a curly-braces block, put your cursor on one of the curly braces and use >% or from anywhere inside block use >iB.

If you’re copying blocks of text around and need to align the indent of a block in its new location, use ]p instead of just p. This aligns the pasted block with the surrounding text.

Also, the shiftwidth setting allows you to control how many spaces to indent.

var str = document.getElementById('mydiv').innerHTML;
document.getElementById('mytextarea').innerHTML = str.replace(/<br\s*[\/]?>/gi, "\n");

or using jQuery:

var str = $("#mydiv").html();
var regex = /<br\s*[\/]?>/gi;
$("#mydiv").html(str.replace(regex, "\n"));

example

edit: added i flag

edit2: you can use /<br[^>]*>/gi which will match anything between the br and slash if you have for example <br class="clear" />

Eclipse Runnable JAR File

Create a Java Project – RunnableJAR

• If any jar files are used then add them to project build path.
• Select the class having main() while creating Runnable Jar file.

Main Class

public class RunnableMainClass {
    public static void main(String[] args) throws InterruptedException {
        System.out.println("Name : "+args[0]);
        System.out.println(" ID  : "+args[1]);
    }
}

Run Jar file using java program (cmd) by supplying arguments and get the output and display in eclipse console.

public class RunJar { 
    static StringBuilder sb = new StringBuilder();
    public static void main(String[] args) throws IOException {
        String jarfile = "D:\\JarLocation\\myRunnable.jar";
        String name = "Yash";
        String id = "777";

        try { // jarname arguments has to be saperated by spaces
            Process process = Runtime.getRuntime().exec("cmd.exe start /C java -jar "+jarfile+" "+name+" "+id);
                    //.exec("cmd.exe /C start dir java -jar "+jarfile+" "+name+" "+id+" dir");
            BufferedReader br = new BufferedReader(new InputStreamReader(process.getInputStream ()));
            String line = null;
            while ((line = br.readLine()) != null){
                sb.append(line).append("\n");
            }
            System.out.println("Console OUTPUT : \n"+sb.toString());
            process.destroy();
        }catch (Exception e){
            System.err.println(e.getMessage());
        }
   }
}

In Eclipse to find Short cuts:

Help ? Help Contents ? Java development user guide ? References ? Menus and Actions

Do you have a local user.name or user.email that's overriding the global one?

git config --list --global | grep user
  user.name=YOUR NAME
  user.email=YOUR@EMAIL
git config --list --local | grep user
  user.name=YOUR NAME
  user.email=

If so, remove them

git config --unset --local user.name
git config --unset --local user.email

The local settings are per-clone, so you'll have to unset the local user.name and user.email for each of the repos on your machine.

'1' >>> Catchall for general errors

'2' >>> Misuse of shell builtins (according to Bash documentation)

'126'>>> Command invoked cannot execute

'127'>>>"command not found"

'128'>>> Invalid argument to exit

'128+n'>>>Fatal error signal "n"

'130'>>> Script terminated by Control-C

'255'>>>Exit status out of range

This is for bash. However, for other applications, there are different exit codes.

In MySQL Workbench 6, commands have been repositioned as the "Server Administration" tab is gone.

You now find the option "Data Export" under the "Management" section when you open a standard server connection.

The self name is used as the instance reference in class instances. It is only used in class method definitions. Don't use it in functions.

You also cannot reference local variables from other functions or methods with it. You can only reference instance or class attributes using it.

This problem is beacouse your proyect is named serial.py and the library imported is name serial too , change the name and thats all.

To get the specific tag code try to create a new branch add get the tag code in it. I have done it by command : $git checkout -b newBranchName tagName
