Programs & Examples On #Dfm

Thank you for your help @jezrael, @zipa and @everestial007, both answers are what I need. If I wanted to make a recursive, this would also work as intended:

def mergefiles(dfs=[], on=''):
    """Merge a list of files based on one column"""
    if len(dfs) == 1:
         return "List only have one element."

    elif len(dfs) == 2:
        df1 = dfs[0]
        df2 = dfs[1]
        df = df1.merge(df2, on=on)
        return df

    # Merge the first and second datafranes into new dataframe
    df1 = dfs[0]
    df2 = dfs[1]
    df = dfs[0].merge(dfs[1], on=on)

    # Create new list with merged dataframe
    dfl = []
    dfl.append(df)

    # Join lists
    dfl = dfl + dfs[2:] 
    dfm = mergefiles(dfl, on)
    return dfm

was implemented that in service-now platform. No need to use other library - makepdf have all you need!

that my html part (include preloder gif):

   <div class="pdf-preview" ng-init="generatePDF(true)">
    <object data="{{c.content}}" type="application/pdf" style="width:58vh;height:88vh;" ng-if="c.content" ></object>
    <div ng-if="!c.content">
      <img src="https://support.lenovo.com/esv4/images/loading.gif" width="50" height="50">
    </div>
  </div>

this is client script (js part)

$scope.generatePDF = function (preview) {
    docDefinition = {} //you rootine to generate pdf content
    //...
    if (preview) {
        pdfMake.createPdf(docDefinition).getDataUrl(function(dataURL) {
            c.content = dataURL;
        });
    }
}

So on page load I fire init function that generate pdf content and if required preview (set as true) result will be assigned to c.content variable. On html side object will be not shown until c.content will got a value, so that will show loading gif.

After many fruitful hours of exploring OCR libraries, bounding boxes and clustering algorithms - I found a solution so simple it makes you want to cry!

I hope you are using Linux;

pdftotext -layout NAME_OF_PDF.pdf

AMAZING!!

Now you have a nice text file with all the information lined up in nice columns, now it is trivial to format into a csv etc..

It is for times like this that I love Linux, these guys came up with AMAZING solutions to everything, and put it there for FREE!

Full disclosure, I am one of the maintainers of pdfminer.six.

Nowadays, there are multiple api's to extract text from a PDF, depending on your needs. Behind the scenes, all of these api's use the same logic for parsing and analyzing the layout.

(All the examples assume your PDF file is called example.pdf)

Commandline

If you want to extract text just once you can use the commandline tool pdf2txt.py:

$ pdf2txt.py example.pdf

High-level api

If you want to extract text with Python, you can use the high-level api. This approach is the go-to solution if you want to extract text programmatically from many PDF's.

from pdfminer.high_level import extract_text

text = extract_text('example.pdf')

Composable api

There is also a composable api that gives a lot of flexibility in handling the resulting objects. For example, you can implement your own layout algorithm using that. This method is suggested in the other answers, but I would only recommend this when you need to customize the way pdfminer.six behaves.

from io import StringIO

from pdfminer.converter import TextConverter
from pdfminer.layout import LAParams
from pdfminer.pdfdocument import PDFDocument
from pdfminer.pdfinterp import PDFResourceManager, PDFPageInterpreter
from pdfminer.pdfpage import PDFPage
from pdfminer.pdfparser import PDFParser

output_string = StringIO()
with open('example.pdf', 'rb') as in_file:
    parser = PDFParser(in_file)
    doc = PDFDocument(parser)
    rsrcmgr = PDFResourceManager()
    device = TextConverter(rsrcmgr, output_string, laparams=LAParams())
    interpreter = PDFPageInterpreter(rsrcmgr, device)
    for page in PDFPage.create_pages(doc):
        interpreter.process_page(page)

print(output_string.getvalue())

According to the grammar in the CSP spec, you need to specify schemes as scheme:, not just scheme. So, you need to change the image source directive to:

img-src 'self' data:;

This is a more general script approach for the stated question.

for encoding in encoding_list:
    worked = True
    try:
        df = pd.read_csv(path, encoding=encoding, nrows=5)
    except:
        worked = False
    if worked:
        print(encoding, ':\n', df.head())

One starts with all the standard encodings available for the python version (in this case 3.7 python 3.7 standard encodings). A usable python list of the standard encodings for the different python version is provided here: Helpful Stack overflow answer

Trying each encoding on a small chunk of the data; only printing the working encoding. The output is directly obvious. This output also addresses the problem that an encoding like 'latin1' that runs through with ought any error, does not necessarily produce the wanted outcome.

In case of the question, I would try this approach specific for problematic CSV file and then maybe try to use the found working encoding for all others.

The direct answer is that you can't. You must select either an aggregate or something that you are grouping by.

So, you need an alternative approach.

1). Take you current query and join the base data back on it

SELECT
  cpe.*
FROM
  Filteredfmgcms_claimpaymentestimate cpe
INNER JOIN
  (yourQuery) AS lookup
    ON  lookup.MaxData           = cpe.createdOn
    AND lookup.fmgcms_cpeclaimid = cpe.fmgcms_cpeclaimid

2). Use a CTE to do it all in one go...

WITH
  sequenced_data AS
(
  SELECT
    *,
    ROW_NUMBER() OVER (PARITION BY fmgcms_cpeclaimid ORDER BY CreatedOn DESC) AS sequence_id
  FROM
    Filteredfmgcms_claimpaymentestimate
  WHERE
    createdon < 'reportstartdate'
)
SELECT
  *
FROM
  sequenced_data
WHERE
  sequence_id = 1

NOTE: Using ROW_NUMBER() will ensure just one record per fmgcms_cpeclaimid. Even if multiple records are tied with the exact same createdon value. If you can have ties, and want all records with the same createdon value, use RANK() instead.

Try this:

// convert from bitmap to byte array
public byte[] getBytesFromBitmap(Bitmap bitmap) {
    ByteArrayOutputStream stream = new ByteArrayOutputStream();
    bitmap.compress(CompressFormat.JPEG, 70, stream);
    return stream.toByteArray();
}

// get the base 64 string
String imgString = Base64.encodeToString(getBytesFromBitmap(someImg), 
                       Base64.NO_WRAP);

If you want to use an iterator, you can do a placement-new with an array.

std::array<int, 10> icloud = new (cloud) std::array<int,10>;

Note the lack of a () at the end, that is important. This creates an array class that uses that memory as its storage, and has STL features like iterators.

(This is C++ TR1/C++11 by the way)

would take time to route through TeamViewer's servers (TeamViewer bypasses corporate Symmetric NATs by simply proxying traffic through their servers)

You'll find that TeamViewer rarely needs to relay traffic through their own servers. TeamViewer penetrates NAT and networks complicated by NAT using NAT traversal (I think it is UDP hole-punching, like Google's libjingle).

They do use their own servers to middle-man in order to do the handshake and connection set-up, but most of the time the relationship between client and server will be P2P (best case, when the hand-shake is successful). If NAT traversal fails, then TeamViewer will indeed relay traffic through its own servers.

I've only ever seen it do this when a client has been behind double-NAT, though.

I found a very nice solution on this site : http://weblogs.sqlteam.com/mladenp/archive/2014/01/10/simple-merging-of-pdf-documents-with-itextsharp-5-4-5.aspx

I update the method in this mode :

    public static bool MergePDFs(IEnumerable<string> fileNames, string targetPdf)
    {
        bool merged = true;
        using (FileStream stream = new FileStream(targetPdf, FileMode.Create))
        {
            Document document = new Document();
            PdfCopy pdf = new PdfCopy(document, stream);
            PdfReader reader = null;
            try
            {
                document.Open();
                foreach (string file in fileNames)
                {
                    reader = new PdfReader(file);
                    pdf.AddDocument(reader);
                    reader.Close();
                }
            }
            catch (Exception)
            {
                merged = false;
                if (reader != null)
                {
                    reader.Close();
                }
            }
            finally
            {
                if (document != null)
                {
                    document.Close();
                }
            }
        }
        return merged;
    }

Open Office / LibreOffice based solutions will do an OK job, but don't expect your PDFs to resemble your source files if they were created in MS-Office. A PDF that looks 90% like the original is not considered to be acceptable in many fields.

The only way to make sure your PDFs look exactly like the originals is to use a solution that uses the official MS-Office DLLs under the hood. If you are running your PHP solution on non-Windows based servers then it requires an additional Windows Server. This may be a showstopper, but if you really care about the look and feel of your PDFs you may not have an option.

Have a look at this blog post. It shows how to use PHP to convert MS-Office files with a high level of fidelity.

Disclaimer: I wrote this blog post and worked on a related commercial product, so consider me biased. However, it appears to be a great solution for the PHP people I work with.

Instead of .encode('utf-8'), use .encode('latin-1').

i used chardet to detect possible encoding of this data ( if its text ), but get {'confidence': 0.0, 'encoding': None}. Then i tried to use pickle.load and get nothing again. I tried to save this as file , test many different formats and failed here too. Maybe you tell us what type have this 16512 bytes of mysterious data?

Why not set sample.png as background image of text or h2 css class? This will give effect as you have written over an image.

 $curl = curl_init();
 curl_setopt_array($curl, array(
            CURLOPT_URL => "http://example.com",
            CURLOPT_RETURNTRANSFER => true,
            CURLOPT_ENCODING => "",
            CURLOPT_MAXREDIRS => 10,
            CURLOPT_TIMEOUT => 30,
            CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
            CURLOPT_CUSTOMREQUEST => "POST",
            CURLOPT_POSTFIELDS => "value1=111&value2=222",
            CURLOPT_HTTPHEADER => array(
                "cache-control: no-cache",
                "content-type: application/x-www-form-urlencoded"
            ),
        ));
 $response = curl_exec($curl);
 $err = curl_error($curl);

 curl_close($curl);

 if (!$err)
 {
      var_dump($response);
 }

df.isnull().sum()

This will give you count of all NaN values present in the respective coloums of the DataFrame.

You can do this in jquery by setting the attribute disabled to 'disabled'.

$(this).prop('disabled', true);

just remove float: left and replace align with margin: 0 auto and it will be centered.

Steps that worked for me on Ubuntu 8.04.2 to remove postgres 8.3

1. List All Postgres related packages

   dpkg -l | grep postgres
   
   ii  postgresql                            8.3.17-0ubuntu0.8.04.1           object-relational SQL database (latest versi

   ii  postgresql-client                     8.3.9-0ubuntu8.04                front-end programs for PostgreSQL (latest ve
   ii  postgresql-client-8.3                 8.3.9-0ubuntu8.04                front-end programs for PostgreSQL 8.3
   ii  postgresql-client-common              87ubuntu2                        manager for multiple PostgreSQL client versi
   ii  postgresql-common                     87ubuntu2                        PostgreSQL database-cluster manager
   ii  postgresql-contrib                    8.3.9-0ubuntu8.04                additional facilities for PostgreSQL (latest
   ii  postgresql-contrib-8.3                8.3.9-0ubuntu8.04                additional facilities for PostgreSQL
   

2. Remove all above listed

   sudo apt-get --purge remove postgresql postgresql-8.3  postgresql-client  postgresql-client-8.3 postgresql-client-common postgresql-common  postgresql-contrib postgresql-contrib-8.3
   

3. Remove the following folders

   sudo rm -rf /var/lib/postgresql/
   sudo rm -rf /var/log/postgresql/
   sudo rm -rf /etc/postgresql/
   

You have 3 options:

1) Get default value

dt = datetime??DateTime.Now;

it will assign DateTime.Now (or any other value which you want) if datetime is null

2) Check if datetime contains value and if not return empty string

if(!datetime.HasValue) return "";
dt = datetime.Value;

3) Change signature of method to

public string ConvertToPersianToShow(DateTime  datetime)

It's all because DateTime? means it's nullable DateTime so before assigning it to DateTime you need to check if it contains value and only then assign.

To force LF line endings for all text files, you can create .gitattributes file in top-level of your repository with the following lines (change as desired):

# Ensure all C and PHP files use LF.
*.c         eol=lf
*.php       eol=lf

which ensures that all files that Git considers to be text files have normalized (LF) line endings in the repository (normally core.eol configuration controls which one do you have by default).

Based on the new attribute settings, any text files containing CRLFs should be normalized by Git. If this won't happen automatically, you can refresh a repository manually after changing line endings, so you can re-scan and commit the working directory by the following steps (given clean working directory):

$ echo "* text=auto" >> .gitattributes
$ rm .git/index     # Remove the index to force Git to
$ git reset         # re-scan the working directory
$ git status        # Show files that will be normalized
$ git add -u
$ git add .gitattributes
$ git commit -m "Introduce end-of-line normalization"

or as per GitHub docs:

git add . -u
git commit -m "Saving files before refreshing line endings"
git rm --cached -r . # Remove every file from Git's index.
git reset --hard # Rewrite the Git index to pick up all the new line endings.
git add . # Add all your changed files back, and prepare them for a commit.
git commit -m "Normalize all the line endings" # Commit the changes to your repository.

See also: @Charles Bailey post.

In addition, if you would like to exclude any files to not being treated as a text, unset their text attribute, e.g.

manual.pdf      -text

Or mark it explicitly as binary:

# Denote all files that are truly binary and should not be modified.
*.png binary
*.jpg binary

To see some more advanced git normalization file, check .gitattributes at Drupal core:

# Drupal git normalization
# @see https://www.kernel.org/pub/software/scm/git/docs/gitattributes.html
# @see https://www.drupal.org/node/1542048

# Normally these settings would be done with macro attributes for improved
# readability and easier maintenance. However macros can only be defined at the
# repository root directory. Drupal avoids making any assumptions about where it
# is installed.

# Define text file attributes.
# - Treat them as text.
# - Ensure no CRLF line-endings, neither on checkout nor on checkin.
# - Detect whitespace errors.
#   - Exposed by default in `git diff --color` on the CLI.
#   - Validate with `git diff --check`.
#   - Deny applying with `git apply --whitespace=error-all`.
#   - Fix automatically with `git apply --whitespace=fix`.

Another approach to this would be to download Jan Karel Pieterse's free Open XML class module from this page: Editing elements in an OpenXML file using VBA

With this added to your VBA project, you can unzip the Excel file, use VBA to modify the XML, then use the class to rezip the files.

Try to use appendChild method:

select.appendChild(option);

To me, it seems as if your actual intention is to put different words on different lines. But let me answer your first question:

JLabel lab=new JLabel("text");
lab.setHorizontalAlignment(SwingConstants.LEFT);     

And if you have an image:

JLabel lab=new Jlabel("text");
lab.setIcon(new ImageIcon("path//img.png"));
lab.setHorizontalTextPosition(SwingConstants.LEFT);

But, I believe you want to make the label such that there are only 2 words on 1 line.

In that case try this:

String urText="<html>You can<br>use basic HTML<br>in Swing<br> components," 
   +"Hope<br> I helped!";
JLabel lac=new JLabel(urText);
lac.setAlignmentX(Component.RIGHT_ALIGNMENT);

For many users you have to enable the windows feature on then check IIS and then go with RUN followed by searching for inetmgr.

Using regular ng-view module you cannot have more than one dynamic template.

However, this project enables you to do so (look for ui-router).

I use Eclipse for cross compiling and I have to add the explicit directories for some of the standard C++ libraries. Right click your project and select Properties. You'll get the dialog shown in the image. Follow the image and use the + icon to explicitly add the paths to your C++ libraries.

org.apache.commons.collections.MapUtils.invertMap(java.util.Map map)

Sample code

HashMap<String, Character> reversedHashMap = MapUtils.invertMap(myHashMap) 

str.casefold is recommended for case-insensitive string matching. @nmichaels's solution can trivially be adapted.

Use either:

if 'MICHAEL89'.casefold() in (name.casefold() for name in USERNAMES):

Or:

if 'MICHAEL89'.casefold() in map(str.casefold, USERNAMES):

As per the docs:

Casefolding is similar to lowercasing but more aggressive because it is intended to remove all case distinctions in a string. For example, the German lowercase letter 'ß' is equivalent to "ss". Since it is already lowercase, lower() would do nothing to 'ß'; casefold() converts it to "ss".

cast(str_column as int)

While waiting for read() or write() to/from a file descriptor return, the process will be put in a special kind of sleep, known as "D" or "Disk Sleep". This is special, because the process can not be killed or interrupted while in such a state. A process waiting for a return from ioctl() would also be put to sleep in this manner.

An exception to this is when a file (such as a terminal or other character device) is opened in O_NONBLOCK mode, passed when its assumed that a device (such as a modem) will need time to initialize. However, you indicated block devices in your question. Also, I have never tried an ioctl() that is likely to block on a fd opened in non blocking mode (at least not knowingly).

How another process is chosen depends entirely on the scheduler you are using, as well as what other processes might have done to modify their weights within that scheduler.

Some user space programs under certain circumstances have been known to remain in this state forever, until rebooted. These are typically grouped in with other "zombies", but the term would not be correct as they are not technically defunct.

@RequestMapping(value = "/books", method = { RequestMethod.GET, 
RequestMethod.POST })
public ModelAndView listBooks(@ModelAttribute("booksFilter") BooksFilter filter,
     HttpServletRequest request) 
    throws ParseException {

//your code 
}

This will works for both GET and POST.

For GET if your pojo(BooksFilter) have to contain the attribute which you're using in request parameter

like below

public class BooksFilter{

private String parameter1;
private String parameter2;

   //getters and setters

URl should be like below

/books?parameter1=blah

Like this way u can use it for both GET and POST

You need to declare an array in another array.

$arr = array(array(content), array(content));

Example:

$arr = array(array(1,2,3), array(4,5,6));

To get the first item from the array, you'll use $arr[0][0], that's like the first item from the first array from the array. $arr[1][0] will return the first item from the second array from the array.

you can get it from here https://slproweb.com/products/Win32OpenSSL.html

A very simple check you can do with Cell formulas:

Sheet 1 (new - old)

=(if(AND(Ref_New<>"";Ref_Old="");Ref_New;"")

Sheet 2 (old - new)

=(if(AND(Ref_Old<>"";Ref_New="");Ref_Old;"")

This formulas should work for an ENGLISH Excel. For other languages they need to be translated. (For German i can assist)

You need to open all three Excel Documents, then copy the first formula into A1 of your sheet 1 and the second into A1 of sheet 2. Now click in A1 of the first cell and mark "Ref_New", now you can select your reference, go to the new file and click in the A1, go back to sheet1 and do the same for "Ref_Old" with the old file. Replace also the other "Ref_New".

Doe the same for Sheet two.

Now copy the formaula form A1 over the complete range where zour data is in the old and the new file.

But two cases are not covered here:

1. In the compared cell of New and Old is the same data (Resulting Cell will be empty)
2. In the compared cell of New and Old is diffe data (Resulting Cell will be empty)

To cover this two cases also, you should create your own function, means learn VBA. A very useful Excel page is cpearson.com

It can block your page

document.write only works while the page is loading; If you call it after the page is done loading, it will overwrite the whole page.

This effectively means you have to call it from an inline script block - And that will prevent the browser from processing parts of the page that follow. Scripts and Images will not be downloaded until the writing block is finished.

rem This is the command line version
cscript "C:\Users\guest\Desktop\123\MyScript.vbs"

OR

rem This is the windowed version
wscript "C:\Users\guest\Desktop\123\MyScript.vbs"

You can also add the option //e:vbscript to make sure the scripting engine will recognize your script as a vbscript.

Windows/DOS batch files doesn't require escaping \ like *nix.

You can still use "C:\Users\guest\Desktop\123\MyScript.vbs", but this requires the user has *.vbs associated to wscript.

Apache Commons Daemon is a good alternative. It has Procrun for windows services, and Jsvc for unix daemons. It uses less restrictive Apache license, and Apache Tomcat uses it as a part of itself to run on Windows and Linux! To get it work is a bit tricky, but there is an exhaustive article with working example.

Besides that, you may look at the bin\service.bat in Apache Tomcat to get an idea how to setup the service. In Tomcat they rename the Procrun binaries (prunsrv.exe -> tomcat6.exe, prunmgr.exe -> tomcat6w.exe).

Something I struggled with using Procrun, your start and stop methods must accept the parameters (String[] argv). For example "start(String[] argv)" and "stop(String[] argv)" would work, but "start()" and "stop()" would cause errors. If you can't modify those calls, consider making a bootstrapper class that can massage those calls to fit your needs.

protected void TestSubmit_ServerClick(object sender, EventArgs e)
{
    using (StreamWriter w = new StreamWriter(Server.MapPath("~/data.txt"), true))
    {
        w.WriteLine(TextBox1.Text); // Write the text
    }
}

WITH UPD AS (UPDATE TEST_TABLE SET SOME_DATA = 'Joe' WHERE ID = 2 
RETURNING ID),
INS AS (SELECT '2', 'Joe' WHERE NOT EXISTS (SELECT * FROM UPD))
INSERT INTO TEST_TABLE(ID, SOME_DATA) SELECT * FROM INS

When in doubt, read the documentation:

filename = "C:\Temp\vblist.txt"

Set fso = CreateObject("Scripting.FileSystemObject")
Set f = fso.OpenTextFile(filename)

Do Until f.AtEndOfStream
  WScript.Echo f.ReadLine
Loop

f.Close

Well I have used the following sample query in my SQL 2000 database, it works well for SQL 2005 too. The power it gives you is dynamically order by using multiple columns. I tell you ... this is powerful :)

    ALTER PROCEDURE [dbo].[RE_ListingReports_SelectSummary] 

@CompanyID  int,
@pageNumber     int,
@pageSize   int, 
@sort       varchar(200)
AS

DECLARE @sql nvarchar(4000)
DECLARE @strPageSize nvarchar(20)
DECLARE @strSkippedRows nvarchar(20)
DECLARE @strFields nvarchar(4000)
DECLARE @strFilter nvarchar(4000)
DECLARE @sortBy nvarchar(4000)
DECLARE @strFrom nvarchar(4000)
DECLARE @strID nvarchar(100)

If(@pageNumber < 0)
  SET @pageNumber = 1
SET @strPageSize = CAST(@pageSize AS varchar(20)) 
SET @strSkippedRows = CAST(((@pageNumber - 1) * @pageSize) AS varchar(20))-- For    example if pageNumber is 5  pageSize is 10, then SkippedRows = 40.
SET @strID = 'ListingDbID'
SET @strFields = 'ListingDbID,
ListingID,  
[ExtraRoom]
'
SET @strFrom = ' vwListingSummary '

SET @strFilter = ' WHERE
        CompanyID = ' + CAST(@CompanyID As varchar(20)) 
End
SET @sortBy = ''
if(len(ltrim(rtrim(@sort))) > 0)
SET @sortBy = ' Order By ' + @sort

-- Total Rows Count

SET @sql =  'SELECT Count(' + @strID + ')  FROM ' + @strFROM + @strFilter
EXEC sp_executesql @sql

--// This technique is used in a Single Table pagination
SET @sql = 'SELECT ' + @strFields + ' FROM ' + @strFROM +
    ' WHERE ' + @strID +  ' IN ' + 
   '  (SELECT TOP ' + @strPageSize + ' ' + @strID + ' FROM ' + @strFROM + @strFilter + 
             ' AND  ' + @strID + ' NOT IN ' + '
          (SELECT TOP ' + @strSkippedRows + ' ' + @strID + ' FROM ' + @strFROM + @strFilter + @SortBy + ') ' 
   + @SortBy + ') ' + @SortBy
Print @sql 
EXEC sp_executesql @sql

The best part is sp_executesql caches later calls, provided you pass same parameters i.e generate same sql text.

Pandas uses numpy's NaN value. Use numpy.isnan to obtain a Boolean vector from a pandas series.

You have not defined the variable input_line.

Add this:

string input_line;

And add this include.

#include <string>

Here is the full example. I also removed the semi-colon after the while loop, and you should have getline inside the while to properly detect the end of the stream.

#include <iostream>
#include <string>

int main() {
    for (std::string line; std::getline(std::cin, line);) {
        std::cout << line << std::endl;
    }
    return 0;
}

Using the trick

Attribute VB_PredeclaredId = True

I found another more compact way:

Option Explicit
Option Base 0
Option Compare Binary

Private v_cBox As ComboBox

'
' Class creaor
Public Function New_(ByRef cBox As ComboBox) As ComboBoxExt_c
  If Me Is ComboBoxExt_c Then
    Set New_ = New ComboBoxExt_c
    Call New_.New_(cBox)
  Else
    Set v_cBox = cBox
  End If
End Function

As you can see the New_ constructor is called to both create and set the private members of the class (like init) only problem is, if called on the non-static instance it will re-initialize the private member. but that can be avoided by setting a flag.

Do it in 2 steps. First, create a dictionary.

>>> input = [('11013331', 'KAT'), ('9085267', 'NOT'), ('5238761', 'ETH'), ('5349618', 'ETH'), ('11788544', 'NOT'), ('962142', 'ETH'), ('7795297', 'ETH'), ('7341464', 'ETH'), ('9843236', 'KAT'), ('5594916', 'ETH'), ('1550003', 'ETH')]
>>> from collections import defaultdict
>>> res = defaultdict(list)
>>> for v, k in input: res[k].append(v)
...

Then, convert that dictionary into the expected format.

>>> [{'type':k, 'items':v} for k,v in res.items()]
[{'items': ['9085267', '11788544'], 'type': 'NOT'}, {'items': ['5238761', '5349618', '962142', '7795297', '7341464', '5594916', '1550003'], 'type': 'ETH'}, {'items': ['11013331', '9843236'], 'type': 'KAT'}]

It is also possible with itertools.groupby but it requires the input to be sorted first.

>>> sorted_input = sorted(input, key=itemgetter(1))
>>> groups = groupby(sorted_input, key=itemgetter(1))
>>> [{'type':k, 'items':[x[0] for x in v]} for k, v in groups]
[{'items': ['5238761', '5349618', '962142', '7795297', '7341464', '5594916', '1550003'], 'type': 'ETH'}, {'items': ['11013331', '9843236'], 'type': 'KAT'}, {'items': ['9085267', '11788544'], 'type': 'NOT'}]

Note both of these do not respect the original order of the keys. You need an OrderedDict if you need to keep the order.

>>> from collections import OrderedDict
>>> res = OrderedDict()
>>> for v, k in input:
...   if k in res: res[k].append(v)
...   else: res[k] = [v]
... 
>>> [{'type':k, 'items':v} for k,v in res.items()]
[{'items': ['11013331', '9843236'], 'type': 'KAT'}, {'items': ['9085267', '11788544'], 'type': 'NOT'}, {'items': ['5238761', '5349618', '962142', '7795297', '7341464', '5594916', '1550003'], 'type': 'ETH'}]

You can use this to merge date and time into the same column of dataframe.

import pandas as pd    
data_file = 'data.csv' #path of your file

Reading .csv file with merged columns Date_Time:

data = pd.read_csv(data_file, parse_dates=[['Date', 'Time']]) 

You can use this line to keep both other columns also.

data.set_index(['Date', 'Time'], drop=False)

Its Very simple

variable.GetType().Name

it will return your datatype of your variable

This took me a while to figure out, as the conventional window['someFunctionName']() did not work for me at first. The names of my functions were being pulled as an AJAX response from a database. Also, for whatever reason, my functions were declared outside of the scope of the window, so in order to fix this I had to rewrite the functions I was calling from

function someFunctionName() {}

to

window.someFunctionName = function() {}

and from there I could call window['someFunctionName']() with ease. I hope this helps someone!

Lookup pom.xml > project tag > build tag.

I would like solution below.

    <finalName>${project.artifactId}</finalName>
  OR
    <finalName>${project.name}</finalName>

Worked for me. ^^

You can put the img tag in a div tag and do both, but I would recommend against scaling images in the browser. It does a lousy job most of the time because browsers have very simplistic scaling algorithms. Better to do your scaling in Photoshop or ImageMagick first, then serve it up to the client nice and pretty.

Previous answers assume that the array is a python standard list. As someone who uses numpy often, I'd recommend a very pythonic test of:

if hasattr(N, "__len__")

You can specify border separately for all borders, for example:

#testdiv{
  border-left: 1px solid #000;
  border-right: 2px solid #FF0;
}

You can also specify the look of the border, and use separate style for the top, right, bottom and left borders. for example:

#testdiv{
  border: 1px #000;
  border-style: none solid none solid;
}

what u need to do is icons downloaded from material design, open that folder there are lots of icons categories specified, open any of it choose any icon and go to this folder -> drawable-anydpi-v21. this folder contains xml files copy any xml file and paste it to this location -> C:\Users\Username\AndroidStudioProjects\ur project name\app\src\main\res\drawable. That's it !! now you can use the icon in ur project.

try

 yum install php-pdo
 yum install php-pdo_mysql

 service httpd restart

Google crawlers are not smart enough, they can't crawl relative URLs, that's why it's always recommended to use absolute URL's for better crawlability and indexability.

Therefore, you can not use this variation

> sitemap: /sitemap.xml

Recommended syntax is

Sitemap: https://www.yourdomain.com/sitemap.xml

Note:

• Don't forgot to capitalise the first letter in "sitemap"
• Don't forgot to put space after "Sitemap:"

You can use the selectInstances method in Eclipse Collections. This will involved creating a new collection however so will not be as efficient as the accepted solution which uses casting.

List<CharSequence> parent =
        Arrays.asList("1","2","3", new StringBuffer("4"));
List<String> strings =
        Lists.adapt(parent).selectInstancesOf(String.class);
Assert.assertEquals(Arrays.asList("1","2","3"), strings);

I included StringBuffer in the example to show that selectInstances not only downcasts the type, but will also filter if the collection contains mixed types.

Note: I am a committer for Eclipse Collections.

svn update /path/to/working/copy

If subversion is not in your PATH, then of course

/path/to/subversion/svn update /path/to/working/copy

or if you are in the current root directory of your svn repo (it contains a .svn subfolder), it's as simple as

svn update

you should use extend()

>>> c=[1,2,3]
>>> c.extend(c)
>>> c
[1, 2, 3, 1, 2, 3]

other info: append vs. extend

I would probably build the link manually, like this:

<a href="<%=Url.Action("Subcategory", "Category", new { categoryID = parent.ID }) %>#section12">link text</a>

If you are using IntelliJ IDE just right click on resources package and go to new and then select Resource Boundle it automatically create a .properties file for you. This did work for me .

$(document).ready(function() {
  $('#media').carousel({
    pause: true,
    interval: 40000,
  });
});

By using the above script, you will be able to move the images automaticaly

$(document).ready(function() {
  $('#media').carousel({
    pause: true,
    interval: false,
  });
});

By using the above script, auto-rotation will be blocked because interval is false

Here's the form I've been using in all my code.

private void DoGUISwitch()
{ 
    Invoke( ( MethodInvoker ) delegate {
        object1.Visible = true;
        object2.Visible = false;
    });
} 

I've based this on the blog entry here. I have not had this approach fail me, so I see no reason to complicate my code with a check of the InvokeRequired property.

Hope this helps.

You can implement a class that holds the fields you have in your JSON

class MyData
{
    public string t;
    public bool a;
    public object[] data;
    public string[][] type;
}

and then use the generic version of DeserializeObject:

MyData tmp = JsonConvert.DeserializeObject<MyData>(json);
foreach (string typeStr in tmp.type[0])
{
    // Do something with typeStr
}

I found the jQuery plugin jQuery Watermark to be better than the one listed in the top answer. Why better? Because it supports password input fields. Also, setting the color of the watermark (or other attributes) is as easy as creating a .watermark reference in your CSS file.

I've had this a couple of times. It's especially frustrating as it's right off the bat, and the error message holds no clue as to what might be the issue.

To fix this, right click your project title, in this case "TestMvcApplication" and click build.

This forces the code to compile before you run it. Don't ask me why, but this has been the solution 100% of the time for me.

So there are many ways but one which worked for me is as follows since I already had my requirements.txt file freeze.

So delete old virtual environment with following command use deactivate cd .. rm -r old_virtual_environment

to install virtualenv python package with pip use pip install virtualenv

then check if it's installed correctly use virtualenv --version

jump to your project directory use cd project_directory

now create new virtual environment inside project directory using following use virtualenv name_of_new_virtual_environment

now activate newly created virtual environment use source name_of_new_virtual_environment/bin/activate

now install all project dependencies using following command use pip install -r requirements.txt

If you want to do this in pgadmin, it is much easier. It seems in postgressql, to add a auto increment to a column, we first need to create a auto increment sequence and add it to the required column. I did like this.

1) Firstly you need to make sure there is a primary key for your table. Also keep the data type of the primary key in bigint or smallint. (I used bigint, could not find a datatype called serial as mentioned in other answers elsewhere)

2)Then add a sequence by right clicking on sequence-> add new sequence. If there is no data in the table, leave the sequence as it is, don't make any changes. Just save it. If there is existing data, add the last or highest value in the primary key column to the Current value in Definitions tab as shown below.

3)Finally, add the line nextval('your_sequence_name'::regclass) to the Default value in your primary key as shown below.

Make sure the sequence name is correct here. This is all and auto increment should work.

The exception states that your result is closed. You should examine your code and look for all location where you issue a ResultSet.close() call. Also look for Statement.close() and Connection.close(). For sure, one of them gets called before rs.next() is called.

use SimpleDateFormat to first parse() String to Date and then format() Date to String

I think its because the two machines usually would need to be optimized in different ways. Other than that I have no idea, we run all our applications with the server-database on the same machine - granted we're not public facing - but we've had no problems.

I can't imagine that too many people care about one machine being compromised over both since the web application will usually have nearly unrestricted access to at the very least the data if not the schema inside the database.

Interested in what others might say.

for this question we can also use this method :

Question from sql zoo:
Find all details of the prize won by PETER GRÜNBERG

Non-ASCII characters

ans: select*from nobel where winner like'P% GR%_%berg';

My guess is that you simply need to URL-encode your Base64 string when you include it in the querystring.

Base64 encoding uses some characters which must be encoded if they're part of a querystring (namely + and /, and maybe = too). If the string isn't correctly encoded then you won't be able to decode it successfully at the other end, hence the errors.

You can use the HttpUtility.UrlEncode method to encode your Base64 string:

string msg = "Please click on the link below or paste it into a browser "
             + "to verify your email account.<br /><br /><a href=\""
             + _configuration.RootURL + "Accounts/VerifyEmail.aspx?a="
             + HttpUtility.UrlEncode(userName.Encrypt("verify")) + "\">"
             + _configuration.RootURL + "Accounts/VerifyEmail.aspx?a="
             + HttpUtility.UrlEncode(userName.Encrypt("verify")) + "</a>";

If you only want the filenames and also want any files that have been added (A).

svn st | grep ^[AM] | cut -c9-

Note: The first 7 columns are each one character wide followed by a space then the filename.

Firstly we should understand when we use $.ajax and when we use $.get/$.post

When we require low level control over the ajax request such as request header settings, caching settings, synchronous settings etc.then we should go for $.ajax.

$.get/$.post: When we do not require low level control over the ajax request.Only simple get/post the data to the server.It is shorthand of

$.ajax({
  url: url,
  data: data,
  success: success,
  dataType: dataType
});

and hence we can not use other features(sync,cache etc.) with $.get/$.post.

Hence for low level control(sync,cache,etc.) over ajax request,we should go for $.ajax

 $.ajax({
     type: 'GET',
      url: url,
      data: data,
      success: success,
      dataType: dataType,
      async:false
    });

This will horizontally center an inline-block element without needing to modify its parent's styles:

  display: inline-block;
  position: relative;
  // Move the element to the left by 50% of the container's width
  left: 50%; 
  // Calculates 50% of the element's width, and moves it by that
  // amount across the X-axis to the left
  transform: translateX(-50%);

I have a simple system that is pure JavaScript. It checks for changes in a simple text file that is never cached. When you upload a new version this file is changed. Just put the following JS at the top of the page.

        (function(url, storageName) {_x000D_
            var fromStorage = localStorage.getItem(storageName);_x000D_

                    }_x000D_
                };_x000D_
            }_x000D_
            ;_x000D_
        })("version.txt", "version");

just replace the "version.txt" with your file that is always run and "version" with the name you want to use for your local storage.

Replace this

export default app;

with this

export default App;

Did you check for DataReaders that are not closed and response.redirects before closing the connection or a datareader. Connections stay open when you dont close them before a redirect.

I also had an issue with multiline strings in this scenario. @Iman's backtick(`) solution worked great in the modern browsers but caused an invalid character error in Internet Explorer. I had to use the following:

'@item.MultiLineString.Replace(Environment.NewLine, "<br />")'

Then I had to put the carriage returns back again in the js function. Had to use RegEx to handle multiple carriage returns.

// This will work for the following:
// "hello\nworld"
// "hello<br>world"
// "hello<br />world"
$("#MyTextArea").val(multiLineString.replace(/\n|<br\s*\/?>/gi, "\r"));

I just confirmed that:

cat file.txt | sed "s/\s/,/g"

successfully replaces spaces with commas in Cygwin terminals (mintty 2.9.0). None of the other samples worked for me.

This worked for me in Luna elementary OS

sudo apt-get install libxtst6:i386

In my case since I had a jump host or Bastion host on the way, and because the signatures on these bastion nodes had changed since they were imported into known_hosts file, I just needed to delete those entries/lines from the following file:

/Users/a.abdi-kelishami/.ssh/known_hosts

From above file, delete those lines referring to the bastion hosts.

You can use .replaceWith()

$(function() {_x000D_
_x000D_
  $(".region").click(function(e) {_x000D_
    e.preventDefault();_x000D_
    var content = $(this).html();_x000D_
    $('#map').replaceWith('<div class="region">' + content + '</div>');_x000D_
  });_x000D_
_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
_x000D_
<div id="map">_x000D_
  <div class="region"><a href="link1">region1</a></div>_x000D_

  <div class="region"><a href="link3">region3</a></div>_x000D_
</div>

You could use iotop. It doesn't rely on a kernel patch. It Works with stock Ubuntu kernel

There is a package for it in the Ubuntu repos. You can install it using

sudo apt-get install iotop

According to my practice, I use the 40 x 40 for standard iPad tab bar item icon, 80 X 80 for retina.

From the Apple reference. https://developer.apple.com/library/ios/documentation/UserExperience/Conceptual/MobileHIG/BarIcons.html#//apple_ref/doc/uid/TP40006556-CH21-SW1

If you want to create a bar icon that looks like it's related to the iOS 7 icon family, use a very thin stroke to draw it. Specifically, a 2-pixel stroke (high resolution) works well for detailed icons and a 3-pixel stroke works well for less detailed icons.

Regardless of the icon’s visual style, create a toolbar or navigation bar icon in the following sizes:

About 44 x 44 pixels About 22 x 22 pixels (standard resolution) Regardless of the icon’s visual style, create a tab bar icon in the following sizes:

About 50 x 50 pixels (96 x 64 pixels maximum) About 25 x 25 pixels (48 x 32 pixels maximum) for standard resolution

Easily done in Bootstrap 3 like so:

<a data-toggle="modal" href="remote.html" data-target="#modal">Click me</a>

According to @Shovalt's answer, but in short:

Alternatively you could use the following lines of code

    from sklearn.metrics import f1_score
    metrics.f1_score(y_test, y_pred, labels=np.unique(y_pred))

This should remove your warning and give you the result you wanted, because it no longer considers the difference between the sets, by using the unique mode.

Strings in Python are immutable meaning you cannot replace parts of them.

You can however create a new string that is modified. Mind that this is not semantically equivalent since other references to the old string will not be updated.

You could for instance write a function:

def replace_str_index(text,index=0,replacement=''):
    return '%s%s%s'%(text[:index],replacement,text[index+1:])

And then for instance call it with:

new_string = replace_str_index(old_string,middle)

If you do not feed a replacement, the new string will not contain the character you want to remove, you can feed it a string of arbitrary length.

For instance:

replace_str_index('hello?bye',5)

will return 'hellobye'; and:

replace_str_index('hello?bye',5,'good')

will return 'hellogoodbye'.

Simple solution to drop all the table at once from terminal.

This involved few steps inside your mysql shell (not a one step solution though), this worked me and saved my day.

Worked for Server version: 5.6.38 MySQL Community Server (GPL)

Steps I followed:

 1. generate drop query using concat and group_concat.
 2. use database
 3. turn off / disable foreign key constraint check (SET FOREIGN_KEY_CHECKS = 0;), 
 4. copy the query generated from step 1
 5. re enable foreign key constraint check (SET FOREIGN_KEY_CHECKS = 1;)
 6. run show table

You need to set the scope of the dependency to 'provided' in your POM.

http://maven.apache.org/guides/introduction/introduction-to-dependency-mechanism.html#Dependency_Scope

<dependency>  
  <groupId>javax.servlet</groupId>
  <artifactId>servlet-api</artifactId>
  <version>2.4</version>
  <scope>provided</scope>
</dependency>

Then everything will be fine.

Here is another way to reproduce this error in Python2.7 with numpy:

import numpy as np
a = np.array([1,2,3])
b = np.array([4,5,6])
c = np.concatenate(a,b)   #note the lack of tuple format for a and b
print(c) 

The np.concatenate method produces an error:

TypeError: only length-1 arrays can be converted to Python scalars

If you read the documentation around numpy.concatenate, then you see it expects a tuple of numpy array objects. So surrounding the variables with parens fixed it:

import numpy as np
a = np.array([1,2,3])
b = np.array([4,5,6])
c = np.concatenate((a,b))  #surround a and b with parens, packaging them as a tuple
print(c) 

Then it prints:

[1 2 3 4 5 6]

What's going on here?

That error is a case of bubble-up implementation - it is caused by duck-typing philosophy of python. This is a cryptic low-level error python guts puke up when it receives some unexpected variable types, tries to run off and do something, gets part way through, the pukes, attempts remedial action, fails, then tells you that "you can't reformulate the subspace responders when the wind blows from the east on Tuesday".

In more sensible languages like C++ or Java, it would have told you: "you can't use a TypeA where TypeB was expected". But Python does it's best to soldier on, does something undefined, fails, and then hands you back an unhelpful error. The fact we have to be discussing this is one of the reasons I don't like Python, or its duck-typing philosophy.

I had this message too because today i decided to relocate my different jdk in the same directory. I have decided to uninstall all through program manager of window. After that, of course i had the message below.

"Cannot locate java installation in specified jdkhome C:\Program Files (x86)\Java\jdk1.7.0_60 Do you want to try to use default version ?"

A new install of the jdk does not resolve the problem. Ok you can configure that in menu Tool > java platforms but in my case i had to fix my netbeans.conf

i had the line below

netbeans_jdkhome="C:\Program Files\Java\jdk1.7.0_60"

and i replace it by

netbeans_jdkhome="C:\devtools\Java\jdk1.8.0_25"

ID is suitable for the elements which appears only once Like Logo sidebar container

And Class is suitable for the elements which has same UI but they can be appear more than once. Like

.feed in the #feeds Container

var text = "\"http://www.example1.com\"; \"http://www.example2.com\"";

Using escape sequence of " (quote), you can achieve this

You can place singe quote (') inside double quotes without any issues Like this

var text = "'http://www.ex.com';'http://www.ex2.com'"

Symfony doc to get request data

Finally, the raw data sent with the request body can be accessed using getContent():

$content = $request->getContent();

using LINQ query expression

 IEnumerable<SelectListItem> stores =
        from store in database.Stores
        where store.CompanyID == curCompany.ID
        select new SelectListItem { Value = store.Name, Text = store.ID };

 ViewBag.storeSelector = stores;

or using LINQ extension methods with lambda expressions

 IEnumerable<SelectListItem> stores = database.Stores
        .Where(store => store.CompanyID == curCompany.ID)
        .Select(store => new SelectListItem { Value = store.Name, Text = store.ID });

 ViewBag.storeSelector = stores;

ALTER TABLE foo AUTO_INCREMENT=1

If you've deleted the most recent entries, that should set it to use the next lowest available one. As in, as long as there's no 19 already, deleting 16-18 will reset the autoincrement to use 16.

EDIT: I missed the bit about phpmyadmin. You can set it there, too. Go to the table screen, and click the operations tab. There's an AUTOINCREMENT field there that you can set to whatever you need manually.

I think it is telling you exactly what is wrong. You cannot compare an integer with a varchar. PostgreSQL is strict and does not do any magic typecasting for you. I'm guessing SQLServer does typecasting automagically (which is a bad thing).

If you want to compare these two different beasts, you will have to cast one to the other using the casting syntax ::.

Something along these lines:

create view view1
as 
select table1.col1,table2.col1,table3.col3
from table1 
inner join
table2 
inner join 
table3
on 
table1.col4::varchar = table2.col5
/* Here col4 of table1 is of "integer" type and col5 of table2 is of type "varchar" */
/* ERROR: operator does not exist: integer = character varying */
....;

Notice the varchar typecasting on the table1.col4.

Also note that typecasting might possibly render your index on that column unusable and has a performance penalty, which is pretty bad. An even better solution would be to see if you can permanently change one of the two column types to match the other one. Literately change your database design.

Or you could create a index on the casted values by using a custom, immutable function which casts the values on the column. But this too may prove suboptimal (but better than live casting).

You could probably hack if from this JavaScript code:

/* convert  to \uD83D\uDE4C */
function text_to_unicode(string) {
  'use strict';

  function is_whitespace(c) { return 9 === c || 10 === c || 13 === c || 32 === c;  }
  function left_pad(string) { return Array(4).concat(string).join('0').slice(-1 * Math.max(4, string.length)); }

  string = string.split('').map(function(c){ return "\\u" + left_pad(c.charCodeAt(0).toString(16).toUpperCase()); }).join('');

  return string;
}


/* convert \uD83D\uDE4C to  */
function unicode_to_text(string) {
  var  prefix = "\\\\u"
     , regex  = new RegExp(prefix + "([\da-f]{4})","ig")
     ; 

  string = string.replace(regex, function(match, backtrace1){
    return String.fromCharCode( parseInt(backtrace1, 16) )
  });

  return string;
}

source: iCompile - Yet Another JavaScript Unicode Encode/Decode

As jeb noted, the rest of the loop is skipped but evaluated, which makes the FOR solution too slow for this purpose. An alternative:

set F=1
:nextpart
if not exist "%F%" goto :EOF
echo %F%
set /a F=%F%+1
goto nextpart

You might need to use delayed expansion and call subroutines when using this in loops.

You can also use the root shortcut like so

  <template>
   <div class="container">
    <h1>Recipes</h1>
      <img src="@/assets/burger.jpg" />
   </div>
  </template>

Although this was Nuxt, it should be same with Vue CLI.

#An example for counting matched groups
import re

pattern = re.compile(r'(\w+).(\d+).(\w+).(\w+)', re.IGNORECASE)
search_str = "My 11 Char String"

res = re.match(pattern, search_str)
print(len(res.groups())) # len = 4  
print (res.group(1) ) #My
print (res.group(2) ) #11
print (res.group(3) ) #Char
print (res.group(4) ) #String

 $endOfCycle = date("Y-m", mktime(0, 0, 0, date("m", time())+1 , 15, date("m", time())));

The comment in your code is wrong. INADDR_ANY doesn't put server's IP automatically'. It essentially puts 0.0.0.0, for the reasons explained in mark4o's answer.

A 32 bit floating point number has 23 + 1 bits of mantissa and an 8 bit exponent (-126 to 127 is used though) so the largest number you can represent is:

(1 + 1 / 2 + ... 1 / (2 ^ 23)) * (2 ^ 127) = 
(2 ^ 23 + 2 ^ 23 + .... 1) * (2 ^ (127 - 23)) = 
(2 ^ 24 - 1) * (2 ^ 104) ~= 3.4e38

Just check the dictionary:

d = {'hello':'world'}
if d:
  print 'not empty'
else:
  print 'empty'

d = {}
if d:
  print 'not empty'
else:
  print 'empty'

An even shorter version could be:

s = "i'm from New York..."
s[0] = s.capitalize[0]

Here's my take on comments within package.json / bower.json:

I have file package.json.js that contains a script that exports the actual package.json. Running the script overwrites the old package.json and tells me what changes it made, perfect to help you keep track of automatic changes npm made. That way I can even programmatically define what packages I want to use.

The latest Grunt task is here: https://gist.github.com/MarZab/72fa6b85bc9e71de5991

One super easy thing to do is to think asynchronously when accessing the data you want for the page. Whether reading from a web service, file, data base or something else, use the async model as much as possible. While it won't necessarily help any one page be faster it will help your server perform better overall.

On Linux/unix/MacOSX use core files (you can enable them with ulimit or compatible system call). On Windows use Microsoft error reporting (you can become a partner and get access to your application crash data).

In my case I had a dual-boot system (Windows 10 and Linux) with project folder on NTFS disk. It turned out that on another update Windows 10 enabled by itself "fast startup" in its settings. After I've unchecked it in the Windows - the "error: cannot open .git/FETCH_HEAD: Permission denied" in Linux was gone.

As defined on Wikipedia, this should do it.

euc.dist <- function(x1, x2) sqrt(sum((x1 - x2) ^ 2))

There's also the rdist function in the fields package that may be useful. See here.

EDIT: Changed ** operator to ^. Thanks, Gavin.

Update 2018-01-07 with Spring Boot 1.5.8.RELEASE

Most answers do not provide how to use them (as datasource itself and as transaction), only how to config them.

You can see the runnable example and some explanation in https://www.surasint.com/spring-boot-with-multiple-databases-example/

I copied some code here.

First you have to set application.properties like this

#Database
database1.datasource.url=jdbc:mysql://localhost/testdb
database1.datasource.username=root
database1.datasource.password=root
database1.datasource.driver-class-name=com.mysql.jdbc.Driver

database2.datasource.url=jdbc:mysql://localhost/testdb2
database2.datasource.username=root
database2.datasource.password=root
database2.datasource.driver-class-name=com.mysql.jdbc.Driver

Then define them as providers (@Bean) like this:

@Bean(name = "datasource1")
@ConfigurationProperties("database1.datasource")
@Primary
public DataSource dataSource(){
    return DataSourceBuilder.create().build();
}

@Bean(name = "datasource2")
@ConfigurationProperties("database2.datasource")
public DataSource dataSource2(){
    return DataSourceBuilder.create().build();
}

Note that I have @Bean(name="datasource1") and @Bean(name="datasource2"), then you can use it when we need datasource as @Qualifier("datasource1") and @Qualifier("datasource2") , for example

@Qualifier("datasource1")
@Autowired
private DataSource dataSource;

If you do care about transaction, you have to define DataSourceTransactionManager for both of them, like this:

@Bean(name="tm1")
@Autowired
@Primary
DataSourceTransactionManager tm1(@Qualifier ("datasource1") DataSource datasource) {
    DataSourceTransactionManager txm  = new DataSourceTransactionManager(datasource);
    return txm;
}

@Bean(name="tm2")
@Autowired
DataSourceTransactionManager tm2(@Qualifier ("datasource2") DataSource datasource) {
    DataSourceTransactionManager txm  = new DataSourceTransactionManager(datasource);
    return txm;
}

Then you can use it like

@Transactional //this will use the first datasource because it is @primary

or

@Transactional("tm2")

This should be enough. See example and detail in the link above.

You can use \ to indicate that any line of Ruby continues on the next line. This works with strings too:

string = "this is a \
string that spans lines"

puts string.inspect

will output "this is a string that spans lines"

This error happens because of your Jre version of Eclipse and Tomcat are mismatched ..either change eclipse one to tomcat one or ViceVersa..

Both should be same ..Java version mismatched ..Check it

One possible cause is that you doesn't have permission to write on the build directory.

Solution: Delete all build directory on your project folder and rebuild your application.

If there is a package.json, and in it there is lodash configuration in it. then you should:

npm install

if in the package.json there is no lodash:

npm install --save-dev

Edited Java 8 Solution:

final Drawable drawable = 
    Optional.ofNullable(Common.getDrawableFromUrl(this, product.getMapPath()))
        .orElseGet(() -> getRandomDrawable());

You can declare drawable final in this case.

As Chasmo pointed out, Android doesn't support Java 8 at the moment. So this solution is only possible in other contexts.

I use this on my site and it works great.

<link rel="shortcut icon" type="image/x-icon" href="images/favicon.ico"/>

As per Oracle Glossary :

SID is a unique name for an Oracle database instance. ---> To switch between Oracle databases, users must specify the desired SID <---. The SID is included in the CONNECT DATA parts of the connect descriptors in a TNSNAMES.ORA file, and in the definition of the network listener in the LISTENER.ORA file. Also known as System ID. Oracle Service Name may be anything descriptive like "MyOracleServiceORCL". In Windows, You can your Service Name running as a service under Windows Services.

You should use SID in TNSNAMES.ORA as a better approach.

It looks like the best solution for you is actually a directive. This allows you to still have your controller, but define custom properties for it.

Use this if you need access to variables in the wrapping scope:

angular.module('myModule').directive('user', function ($filter) {
  return {
    link: function (scope, element, attrs) {
      $scope.connection = $resource('api.com/user/' + attrs.userId);
    }
  };
});

<user user-id="{% id %}"></user>

Use this if you don't need access to variables in the wrapping scope:

angular.module('myModule').directive('user', function ($filter) {
  return {
    scope: {
      userId: '@'
    },
    link: function (scope, element, attrs) {
      $scope.connection = $resource('api.com/user/' + scope.userId);
    }
  };
});

<user user-id="{% id %}"></user>

I have used the extremely handy app_offline.htm trick to shut down/update sites in the past without any issues.

Be sure that you are actually placing the "app_offline.htm" file in the "root" of the website that you have configured within IIS.

Also ensure that the file is named exactly as it should be: app_offline.htm

Other than that, there should be no other changes to IIS that you should need to make since the processing of this file (with this specific name) is handled by the ASP.NET runtime rather than IIS itself (for IIS v6).

Be aware, however, that although placing this file in the root of your site will force the application to "shut down" and display the content of the "app_offline.htm" file itself, any existing requests will still get the real website served up to them. Only new requests will get the app_offline.htm content.

If you're still having issues, try the following links for further info:

Scott Gu's App_Offline.htm

App_Offline.htm and working around the "IE Friendly Errors" feature

Will app_offline.htm stop current requests or just new requests?

You can simply use target="_blank" to open a page in a new tab

<a href="whatever.php" target="_blank">Opens On Another Tab</a>

Or you can simply use a javascript for onload

<body onload="window.open(url, '_blank');">

I think that Alex Martelli's answer is definitely the most elegant way to do this, but just wanted to add a way to satisfy your want for a super awesome dictionary.filter(f) method in a Pythonic sort of way:

class FilterDict(dict):
    def __init__(self, input_dict):
        for key, value in input_dict.iteritems():
            self[key] = value
    def filter(self, criteria):
        for key, value in self.items():
            if (criteria(value)):
                self.pop(key)

my_dict = FilterDict( {'a':(3,4), 'b':(1,2), 'c':(5,5), 'd':(3,3)} )
my_dict.filter(lambda x: x[0] < 5 and x[1] < 5)

Basically we create a class that inherits from dict, but adds the filter method. We do need to use .items() for the the filtering, since using .iteritems() while destructively iterating will raise exception.

When you have two docker images "already" created and you want to put two containers to communicate with one-another.

For that, you can conveniently run each container with its own --name and use the --link flag to enable communication between them. You do not get this during docker build though.

When you are in a scenario like myself, and it is your

docker build -t "centos7/someApp" someApp/ 

That breaks when you try to

curl http://172.17.0.1:localPort/fileIWouldLikeToDownload.tar.gz > dump.tar.gz

and you get stuck on "curl/wget" returning no "route to host".

The reason is security that is set in place by docker that by default is banning communication from a container towards the host or other containers running on your host. This was quite surprising to me, I must say, you would expect the echosystem of docker machines running on a local machine just flawlessly can access each other without too much hurdle.

The explanation for this is described in detail in the following documentation.

http://www.dedoimedo.com/computers/docker-networking.html

Two quick workarounds are given that help you get moving by lowering down the network security.

The simplest alternative is just to turn the firewall off - or allow all. This means running the necessary command, which could be systemctl stop firewalld, iptables -F or equivalent.

Hope this information helps you.

I searched for this very question and when I saw the answers I ended up creating something different (because I favor less code over most other things most of the time) that should work in the vast majority of cases. Basically turn the array into a string with array elements separated by some delimiter character, and then wrap the search value in the delimiter character and pass through instr.

Function is_in_array(value As String, test_array) As Boolean
    If Not (IsArray(test_array)) Then Exit Function
    If InStr(1, "'" & Join(test_array, "'") & "'", "'" & value & "'") > 0 _
        Then is_in_array = True
End Function

And you'd execute the function like this:

test = is_in_array(1, array(1, 2, 3))

Within your .bat file:

set mypath=%cd%

You can now use the variable %mypath% to reference the file path to the .bat file. To verify the path is correct:

@echo %mypath%

For example, a file called DIR.bat with the following contents

set mypath=%cd%
@echo %mypath%
Pause

run from the directory g:\test\bat will echo that path in the DOS command window.

Create a new immutable map:

scala> val m1 = Map("k0" -> "v0")   
m1: scala.collection.immutable.Map[String,String] = Map(k0 -> v0)

Add a new key/value pair to the above map (and create a new map, since they're both immutable):

scala> val m2 = m1 + ("k1" -> "v1")             
m2: scala.collection.immutable.Map[String,String] = Map(k0 -> v0, k1 -> v1)

You can open a command prompt and do a

route print

and see your current routing table.

You can modify it by

route add    d.d.d.d mask m.m.m.m g.g.g.g 
route delete d.d.d.d mask m.m.m.m g.g.g.g 
route change d.d.d.d mask m.m.m.m g.g.g.g

these seem to work

I run a ping d.d.d.d -t change the route and it changes. (my test involved routing to a dead route and the ping stopped)

<a [routerLink]="['../']" [queryParams]="{name: 'ferret'}" [fragment]="nose">Ferret Nose</a>

Poor man's tests

const test = () => {

    const length = values.length;
    console.group(`${label} (${length} tests)`);
    values.map((v, i) => {

    new WeakMap().set({}, 1),
    new Date(), /a/, new RegExp(), () => {},
  ];
  const shouldBeEmpty = [
    {undefined: undefined}, new Map([[]]),
  ];

  run('EMPTY', empty, true);
  run('NOT EMPTY', notEmpty, false);
  run('SHOULD BE EMPTY', shouldBeEmpty, true);

This CSS effectively hides the spin-button for webkit browsers (have tested it in Chrome 7.0.517.44 and Safari Version 5.0.2 (6533.18.5)):

input::-webkit-outer-spin-button,_x000D_
input::-webkit-inner-spin-button {_x000D_
    /* display: none; <- Crashes Chrome on hover */_x000D_
    -webkit-appearance: none;_x000D_
    margin: 0; /* <-- Apparently some margin are still there even though it's hidden */_x000D_
}_x000D_
_x000D_
input[type=number] {_x000D_
    -moz-appearance:textfield; /* Firefox */_x000D_
}

<input type="number" step="0.01" />

You can always use the inspector (webkit, possibly Firebug for Firefox) to look for matched CSS properties for the elements you are interested in, look for Pseudo elements. This image shows results for an input element type="number":

Another way to do it is using the StructField if you have multiple fields that needs to be modified.

Ex:

from pyspark.sql.types import StructField,IntegerType, StructType,StringType
newDF=[StructField('CLICK_FLG',IntegerType(),True),
       StructField('OPEN_FLG',IntegerType(),True),
       StructField('I1_GNDR_CODE',StringType(),True),
       StructField('TRW_INCOME_CD_V4',StringType(),True),
       StructField('ASIAN_CD',IntegerType(),True),
       StructField('I1_INDIV_HHLD_STATUS_CODE',IntegerType(),True)
       ]
finalStruct=StructType(fields=newDF)
df=spark.read.csv('ctor.csv',schema=finalStruct)

Output:

Before

root
 |-- CLICK_FLG: string (nullable = true)
 |-- OPEN_FLG: string (nullable = true)
 |-- I1_GNDR_CODE: string (nullable = true)
 |-- TRW_INCOME_CD_V4: string (nullable = true)
 |-- ASIAN_CD: integer (nullable = true)
 |-- I1_INDIV_HHLD_STATUS_CODE: string (nullable = true)

After:

root
 |-- CLICK_FLG: integer (nullable = true)
 |-- OPEN_FLG: integer (nullable = true)
 |-- I1_GNDR_CODE: string (nullable = true)
 |-- TRW_INCOME_CD_V4: string (nullable = true)
 |-- ASIAN_CD: integer (nullable = true)
 |-- I1_INDIV_HHLD_STATUS_CODE: integer (nullable = true)

This is slightly a long procedure to cast , but the advantage is that all the required fields can be done.

It is to be noted that if only the required fields are assigned the data type, then the resultant dataframe will contain only those fields which are changed.

If you want to return a boolean value, then you can use something like this (much faster than filter):

players.stream().anyMatch(player -> player.getName().contains(name));

I set the PHPRC variable and uncommented zend_extension=php_opcache.dll in php.ini and all works well.

There are three options for copying it if this is a one off:

1. Use a db_link (I think it is still in contrib)
2. Have the application do the work.
3. Export/import

If this is an ongoing need, the answers are:

1. Change to schemas in the same DB
2. db_link

Using attr() pointing to an external domain may trigger an error like this in Chrome: "Refused to display document because display forbidden by X-Frame-Options". The workaround to this can be to move the whole iframe HTML code into the script (eg. using .html() in jQuery).

Example:

var divMapLoaded = false;
$("#container").scroll(function() {
    if ((!divMapLoaded) && ($("#map").position().left <= $("#map").width())) {
    $("#map-iframe").html("<iframe id=\"map-iframe\" " +
        "width=\"100%\" height=\"100%\" frameborder=\"0\" scrolling=\"no\" " +
        "marginheight=\"0\" marginwidth=\"0\" " +
        "src=\"http://www.google.it/maps?t=m&amp;cid=0x3e589d98063177ab&amp;ie=UTF8&amp;iwloc=A&amp;brcurrent=5,0,1&amp;ll=41.123115,16.853177&amp;spn=0.005617,0.009943&amp;output=embed\"" +
        "></iframe>");
    divMapLoaded = true;
}

How to insert some Text to current cursor position of a TextBox through JQuery and JavaScript

Process

1. Find the Current Cursor Position
2. Get the Text to be Copied
3. Set the Text Over there
4. Update the Cursor position

Here I have 2 TextBoxes and a Button. I have to Click on a certain position on a textbox and then click on the button to paste the text from the other textbox to the the position of the previous textbox.

Main issue here is that getting the current cursor position where we will paste the text.

//Textbox on which to be pasted
<input type="text" id="txtOnWhichToBePasted" />

//Textbox from where to be pasted
<input type="text" id="txtFromWhichToBePasted" />


//Button on which click the text to be pasted
<input type="button" id="btnInsert" value="Insert"/>


<script type="text/javascript">

$(document).ready(function () {
    $('#btnInsert').bind('click', function () {
            var TextToBePasted = $('#txtFromWhichToBePasted').value;
            var ControlOnWhichToBePasted = $('#txtOnWhichToBePasted');

            //Paste the Text
            PasteTag(ControlOnWhichToBePasted, TextToBePasted);
        });
    });

//Function Pasting The Text
function PasteTag(ControlOnWhichToBePasted,TextToBePasted) {
    //Get the position where to be paste

    var CaretPos = 0;
    // IE Support
    if (document.selection) {

        ControlOnWhichToBePasted.focus();
        var Sel = document.selection.createRange();

        Sel.moveStart('character', -ctrl.value.length);

        CaretPos = Sel.text.length;
    }
    // Firefox support
    else if (ControlOnWhichToBePasted.selectionStart || ControlOnWhichToBePasted.selectionStart == '0')
        CaretPos = ControlOnWhichToBePasted.selectionStart;

    //paste the text
    var WholeString = ControlOnWhichToBePasted.value;
    var txt1 = WholeString.substring(0, CaretPos);
    var txt2 = WholeString.substring(CaretPos, WholeString.length);
    WholeString = txt1 + TextToBePasted + txt2;
    var CaretPos = txt1.length + TextToBePasted.length;
    ControlOnWhichToBePasted.value = WholeString;

    //update The cursor position 
    setCaretPosition(ControlOnWhichToBePasted, CaretPos);
}

function setCaretPosition(ControlOnWhichToBePasted, pos) {

    if (ControlOnWhichToBePasted.setSelectionRange) {
        ControlOnWhichToBePasted.focus();
        ControlOnWhichToBePasted.setSelectionRange(pos, pos);
    }
    else if (ControlOnWhichToBePasted.createTextRange) {
        var range = ControlOnWhichToBePasted.createTextRange();
        range.collapse(true);
        range.moveEnd('character', pos);
        range.moveStart('character', pos);
        range.select();
    }
}

</script>

I had also problems in finding something simple to satisfy my needs so I decided to write my own library (with MIT license). It's mainly based on composite and builder pattern.

A basic declarative example is:

import static com.github.manliogit.javatags.lang.HtmlHelper.*;

html5(attr("lang -> en"),
  head(
    meta(attr("http-equiv -> Content-Type", "content -> text/html; charset=UTF-8")),
    title("title"),
    link(attr("href -> xxx.css", "rel -> stylesheet"))
  )
).render();

A fluent example is:

ul()
  .add(li("item 1"))
  .add(li("item 2"))
  .add(li("item 3"))     

You can check more examples here

I also created an on line converter to transform every html snippet (from complex bootstrap template to simple single snippet) on the fly (i.e. html -> javatags)

Here a JScript variant of JohnB's answer

// Below the MSDN page for MapNetworkDrive Method with link and in case if Microsoft breaks it like every now and then the path to the documentation of now.
// https://msdn.microsoft.com/en-us/library/8kst88h6(v=vs.84).aspx
// MSDN Library -> Web Development -> Scripting -> JScript and VBScript -> Windows Scripting -> Windows Script Host -> Reference (Windows Script Host) -> Methods (Windows Script Host) -> MapNetworkDrive Method

var WshNetwork = WScript.CreateObject('WScript.Network');
function localNameInUse(localName) {
    var driveIterator = WshNetwork.EnumNetworkDrives();
    for (var i=0, l=driveIterator.length; i < l; i += 2) {
        if (driveIterator.Item(i) == localName) {
            return true;
        }
    }
    return false;
}

function mount(localName, remoteName) {
    if (localNameInUse(localName)) {
        WScript.Echo('"' + localName + '" drive letter already in use.');
    } else {
        WshNetwork.MapNetworkDrive(localName, remoteName);
    }
}

function unmount(localName) {
    if (localNameInUse(localName)) {
        WshNetwork.RemoveNetworkDrive(localName);
    }
}

Use:

ToolTip tip = new ToolTip();
private void richTextBox1_MouseMove(object sender, MouseEventArgs e)
{
    Cursor a = System.Windows.Forms.Cursor.Current;
    if (a == Cursors.Hand)
    {
        Point p = richTextBox1.Location;
        tip.Show(
            GetWord(richTextBox1.Text,
                richTextBox1.GetCharIndexFromPosition(e.Location)),
            this,
            p.X + e.X,
            p.Y + e.Y + 32,
            1000);
    }
}

Use the GetWord function from my other answer to get the hovered word. Use timer logic to disable reshow the tooltip as in prev. example.

In this example right above, the tool tip shows the hovered word by checking the mouse pointer.

If this answer is still not what you are looking fo, please specify the condition that characterizes the word you want to use tooltip on. If you want it for bolded word, please tell me.

Following is the list of conversion characters that you may use in the printf:

%d – for signed decimal integer

%f – for the floating point

%o – octal number

%c – for a character

%s – a string

%i – use for integer base 10

%u – for unsigned decimal number

%x – hexadecimal number

%% – for writing % (percentage)

%n – for new line = \n

Another way of doing the same could be using the Gson Class

String filename = "path/to/file/abc.json";
Gson gson = new Gson();
JsonReader reader = new JsonReader(new FileReader(filename));
SampleClass data = gson.fromJson(reader, SampleClass.class);

This will give an object obtained after parsing the json string to work with.

There may already be a function to do what you're looking for, but I don't know about it (yet?). In the meantime, I would suggess using:

ran_floats = numpy.random.rand(50) * (13.3-0.5) + 0.5

This will produce an array of shape (50,) with a uniform distribution between 0.5 and 13.3.

You could also define a function:

def random_uniform_range(shape=[1,],low=0,high=1):
    """
    Random uniform range

    Produces a random uniform distribution of specified shape, with arbitrary max and
    min values. Default shape is [1], and default range is [0,1].
    """
    return numpy.random.rand(shape) * (high - min) + min

EDIT: Hmm, yeah, so I missed it, there is numpy.random.uniform() with the same exact call you want! Try import numpy; help(numpy.random.uniform) for more information.

I had the same issue after update on Android Studio 3.2.1 I had to re-import project, after that everything works

You can use Array.push() for appending elements to an array.

For deleting, it is best to use this.$delete(array, index) for reactive objects.

Vue.delete( target, key ): Delete a property on an object. If the object is reactive, ensure the deletion triggers view updates. This is primarily used to get around the limitation that Vue cannot detect property deletions, but you should rarely need to use it.

https://vuejs.org/v2/api/#Vue-delete

$url = 'http://www.example.com'; $xml = simpleXML_load_file($url,"SimpleXMLElement",LIBXML_NOCDATA);

$url can be php file, as long as the file generate xml format data as output.

Another solution, for those of us without an internet connection to our development machine is:

Create a folder called system-images in the top level of your SDK directory (next to platforms and tools). Create subdirs android-14 and android-15 (as applicable). Extract the complete armeabi-v7a folder to these directory; sysimg_armv7a-15_r01.zip (from, e.g. google's repository) goes to android-15, sysimg_armv7a-14_r02.zip to android-14.

I've not tried this procedure offline, I finally relented and used my broadband allowance at home, but these are the target locations for these large sysimg's, for future reference.

I've tried creating the image subdirs where they were absent in 14 and 15 but while this allowed the AVD to create an image (for 15 but not 14) it hadn't shown the Android logo after 15 minutes.

As a summary

import sys
import re

f = sys.argv[1]
find = sys.argv[2]
replace = sys.argv[3]
with open (f, "r") as myfile:
     s=myfile.read()
ret = re.sub(find,replace, s)   # <<< This is where the magic happens
print ret

To my knowledge, you can't mock constructors with mockito, only methods. But according to the wiki on the Mockito google code page there is a way to mock the constructor behavior by creating a method in your class which return a new instance of that class. then you can mock out that method. Below is an excerpt directly from the Mockito wiki:

Pattern 1 - using one-line methods for object creation

To use pattern 1 (testing a class called MyClass), you would replace a call like

   Foo foo = new Foo( a, b, c );

with

   Foo foo = makeFoo( a, b, c );

and write a one-line method

   Foo makeFoo( A a, B b, C c ) { 
        return new Foo( a, b, c );
   }

It's important that you don't include any logic in the method; just the one line that creates the object. The reason for this is that the method itself is never going to be unit tested.

When you come to test the class, the object that you test will actually be a Mockito spy, with this method overridden, to return a mock. What you're testing is therefore not the class itself, but a very slightly modified version of it.

Your test class might contain members like

  @Mock private Foo mockFoo;
  private MyClass toTest = spy(new MyClass());

Lastly, inside your test method you mock out the call to makeFoo with a line like

  doReturn( mockFoo )
      .when( toTest )
      .makeFoo( any( A.class ), any( B.class ), any( C.class ));

You can use matchers that are more specific than any() if you want to check the arguments that are passed to the constructor.

If you're just wanting to return a mocked object of your class I think this should work for you. In any case you can read more about mocking object creation here:

http://code.google.com/p/mockito/wiki/MockingObjectCreation

You need to add a Custom Action to the end of the 'ExecuteImmediate' sequence in the MSI, using the component name of the EXE or a batch (sc start) as the source. I don't think this can be done with Visual Studio, you may have to use a real MSI authoring tool for that.

Make a third column that has values like:

=IF(A1="Airline",B1)

=IF(A2="Airline",B2) etc

Then just perform a median on the new column.

You need to import the module datetime first:

>>> import datetime

After that it works:

>>> import datetime
>>> date = datetime.date.today()
>>> date
datetime.date(2013, 11, 12)

SELECT CONVERT(varchar, @datetime, 103) --for UK Date format 'DD/MM/YYYY'

101 - US - MM/DD/YYYY

108 - Time - HH:MI:SS

112 - Date - YYYYMMDD

121 - ODBC - YYYY-MM-DD HH:MI:SS.FFF

20 - ODBC - YYYY-MM-DD HH:MI:SS

Check, if you are not accidentally requesting HTTPS protocol instead of HTTP.

I have overlooked that I was requesting https://localhost:... instead of http://localhost:... and it resulted to this weird message..

I know this is an older post, but someone will stumble across it in a Google search and it also looks like some questions the OP asked in comments weren't specifically addressed. Also, please go easy on me since this is my first answer posted on SO. :)

To redirect the output to a file using a dynamically generated file name, my go-to (read: quick & dirty) approach is the second solution offered by @dbenham. So for example, this:

@echo off
> filename_prefix-%DATE:~-4%-%DATE:~4,2%-%DATE:~7,2%_%time:~0,2%%time:~3,2%%time:~6,2%.log (
echo Your Name Here
echo Beginning Date/Time: %DATE:~-4%-%DATE:~4,2%-%DATE:~7,2%_%time:~0,2%%time:~3,2%%time:~6,2%.log
REM do some stuff here
echo Your Name Here
echo Ending Date/Time: %DATE:~-4%-%DATE:~4,2%-%DATE:~7,2%_%time:~0,2%%time:~3,2%%time:~6,2%.log
)

Will create a file like what you see in this screenshot of the file in the target directory

That will contain this output:

Your Name Here
Beginning Date/Time: 2016-09-16_141048.log
Your Name Here
Ending Date/Time: 2016-09-16_141048.log

Also keep in mind that this solution is locale-dependent, so be careful how/when you use it.

Perhaps something like this :

LinkedHashMap<Integer, String> myMap;

public String getFirstKey() {
  String out = null;
  for (int key : myMap.keySet()) {
    out = myMap.get(key);
    break;
  }
  return out;
}

public String getLastKey() {

Use Element#outerHTML:

var el = document.createElement("p");
el.appendChild(document.createTextNode("Test"));

console.log(el.outerHTML);

It can also be used to write DOM elements. From Mozilla's documentation:

The outerHTML attribute of the element DOM interface gets the serialized HTML fragment describing the element including its descendants. It can be set to replace the element with nodes parsed from the given string.

https://developer.mozilla.org/en-US/docs/Web/API/Element/outerHTML

Use isinstance, nothing else:

if isinstance(x, pd.DataFrame):
    ... # do something

PEP8 says explicitly that isinstance is the preferred way to check types

No:  type(x) is pd.DataFrame
No:  type(x) == pd.DataFrame
Yes: isinstance(x, pd.DataFrame)

And don't even think about

if obj.__class__.__name__ = 'DataFrame':
    expect_problems_some_day()

isinstance handles inheritance (see What are the differences between type() and isinstance()?). For example, it will tell you if a variable is a string (either str or unicode), because they derive from basestring)

if isinstance(obj, basestring):
    i_am_string(obj)

Specifically for pandas DataFrame objects:

import pandas as pd
isinstance(var, pd.DataFrame)

The Date constructor accepts any value. If the primitive [[value]] of the argument is number, then the Date that is created has that value. If primitive [[value]] is String, then the specification only guarantees that the Date constructor and the parse method are capable of parsing the result of Date.prototype.toString and Date.prototype.toUTCString()

A reliable way to set a Date is to construct one and use the setFullYear and setTime methods.

An example of that appears here: http://jibbering.com/faq/#parseDate

ECMA-262 r3 does not define any date formats. Passing string values to the Date constructor or Date.parse has implementation-dependent outcome. It is best avoided.

/**Parses string formatted as YYYY-MM-DD to a Date object.
 * If the supplied string does not match the format, an 
 * invalid Date (value NaN) is returned.
 * @param {string} dateStringInRange format YYYY-MM-DD, with year in
 * range of 0000-9999, inclusive.
 * @return {Date} Date object representing the string.
 */

  function parseISO8601(dateStringInRange) {
    var isoExp = /^\s*(\d{4})-(\d\d)-(\d\d)\s*$/,
        date = new Date(NaN), month,
        parts = isoExp.exec(dateStringInRange);

    if(parts) {
      month = +parts[2];
      date.setFullYear(parts[1], month - 1, parts[3]);
      if(month != date.getMonth() + 1) {
        date.setTime(NaN);
      }
    }
    return date;
  }

('my string'.match(/\s/g) || []).length;

There's a far easier way:

1. Hit command + space, Spotlight Search will appear
2. Type in iOS Simulator and hit return

Done.

----- In follow up to @E. Maggini downvote---

Yes you can still easily access iOS Simulator using Spotlight.

if( $("#field > div.field-item").text().indexOf('someText') >= 0)

Some browsers will include whitespace, others won't. >= is appropriate here. Otherwise equality is double equals ==

Seems you are using outdated version of django.. Simply update django and try again.. Following command will update your django version..

pip install --upgrade django

go test -v -timeout 30s <path_to_package> -run ^(TestFuncRegEx)

• The TestFunc must be inside a go test file in that package
• We can provide a regular expression to match a set of test cases or just the exact test case function to run a single test case. For instance -run TestCaseFunc

In Dialog.java (Android src) a ContextThemeWrapper is used. So you could copy the idea and do something like:

AlertDialog.Builder builder = new AlertDialog.Builder(new ContextThemeWrapper(this, R.style.AlertDialogCustom));

And then style it like you want:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="AlertDialogCustom" parent="@android:style/Theme.Dialog">
        <item name="android:textColor">#00FF00</item>
        <item name="android:typeface">monospace</item>
        <item name="android:textSize">10sp</item>
    </style>
</resources>

Secondary data files are optional, are user-defined, and store user data. Secondary files can be used to spread data across multiple disks by putting each file on a different disk drive. Additionally, if a database exceeds the maximum size for a single Windows file, you can use secondary data files so the database can continue to grow.

Source: MSDN: Understanding Files and Filegroups

The recommended file name extension for secondary data files is .ndf, but this is not enforced.

I'm jumping in here a little late, but came across this page when pondering it myself. Of course I don't know how Facebook or Twitter justified it, but here is my own thought process for what it's worth.

In the end, I concluded that this practice is not that unsemantic (is that a word?). In fact, besides shortness and the nice association of "i is for icon," I think it's actually the most semantic choice for an icon when a straightforward <img> tag is not practical.

1. The usage is consistent with the spec.

While it may not be what the W3 mainly had in mind, it seems to me the official spec for <i> could accommodate an icon pretty easily. After all, the reply-arrow symbol is saying "reply" in another way. It expresses a technical term that may be unfamiliar to the reader and would be typically italicized. ("Here at Twitter, this is what we call a reply arrow.") And it is a term from another language: a symbolic language.

If, instead of the arrow symbol, Twitter used <i>shout out</i> or <i>[Japanese character for reply]</i> (on an English page), that would be consistent with the spec. Then why not <i>[reply arrow]</i>? (I'm talking strictly HTML semantics here, not accessibility, which I'll get to.)

As far as I can see, the only part of the spec explicitly violated by icon usage is the "span of text" phrase (when the tag doesn't contain text also). It is clear that the <i> tag is mainly meant for text, but that's a pretty small detail compared with the overall intent of the tag. The important question for this tag is not what format of content it contains, but what the meaning of that content is.

This is especially true when you consider that the line between "text" and "icon" can be almost nonexistent on websites. Text may look like more like an icon (as in the Japanese example) or an icon may look like text (as in a jpg button that says "Submit" or a cat photo with an overlaid caption) or text may be replaced or enhanced with an image via CSS. Text, image - who cares? It's all content. As long as everyone - humans with impairments, browsers with impairments, search engine spiders, and other machines of various kinds can understand that meaning, we've done our job.

So the fact that the writers of the spec didn't think (or choose) to clarify this shouldn't tie our hands from doing what makes sense and is consistent with the spirit of the tag. The <a> tag was originally intended to take the user somewhere else, but now it might pop up a lightbox. Big whoop, right? If someone had figured out how to pop up a lightbox on click before the spec caught up, they still should have used the <a> tag, not a <span>, even if it wasn't entirely consistent with the current definition - because it came the closest and was still consistent with the spirit of the tag ("something will happen when you click here"). Same deal with <i> - whatever type of thing you put inside it, or however creatively you use it, it expresses the general idea of an alternate or set-apart term.

2. The <i> tag adds semantic meaning to an icon element.

The alternative option to carry an icon class by itself is <span>, which of course has no semantic meaning whatsoever. When a machine asks the <span> what it contains, it says, "I don't know. Could be anything." But the <i> tag says, "I contain a different way of saying something than the usual way, or maybe an unfamiliar term." That's not the same as "I contain an icon," but it's a lot closer to it than <span> got!

3. Eventually, common usage makes right.

In addition to the above, it's worth considering that machine readers (whether search engine, screen reader, or whatever) may at any time begin to take into account that Facebook, Twitter, and other websites use the <i> tag for icons. They don't care about the spec as much as they care about extracting meaning from code by whatever means necessary. So they might use this knowledge of common usage to simply record that "there may be an icon here" or do something more advanced like triggering a look into the CSS for a hint to meaning, or who knows what. So if you choose to use the <i> for icons on your website, you may be providing more meaning than the spec does.

Moreover, if this usage becomes widespread, it will likely be included in the spec in the future. Then you'll be going through your code, replacing <span>s with <i>'s! So it may make sense to get on board with what seems to be the direction of the spec, especially when it doesn't clearly conflict with the current spec. Common usage tends to dictate language rules more than the other way around. If you're old enough, do you remember that "Web site" was the official spelling when the word was new? Dictionaries insisted there must be a space and Web must be capitalized. There were semantic reasons for that. But common usage said, "Whatever, that's stupid. I'm using 'website' because it's more concise and looks better." And before long, dictionaries officially acknowledged that spelling as correct.

4. So I'm going ahead and using it.

So, <i> provides more meaning to machines because of the spec, it provides more meaning to humans because we easily associate "i" with "icon", and it's only one letter long. Win! And if you make sure to include equivalent text either inside the <i> tag or right next to it (as Twitter does), then screen readers understand where to click to reply, the link is usable if CSS doesn't load, and human readers with good eyesight and a decent browser see a pretty icon. With all this in mind, I don't see the downside.

Though this post has been here for quite a while, the solutions are not pure JS. Though Jason noted that requesting permissions is not ideal, I consider it a good thing since the user can reject it explicitly. I still post this code, though (almost) the same thing can also be seen in another post by ifaour. Consider this the JS only version without too much attention to detail.

The basic code is rather simple:

FB.api("me/likes/SOME_ID", function(response) {
    if ( response.data.length === 1 ) { //there should only be a single value inside "data"
        console.log('You like it');
    } else {
        console.log("You don't like it");
    }
});

ALternatively, replace me with the proper UserID of someone else (you might need to alter the permissions below to do this, like friends_likes) As noted, you need more than the basic permission:

FB.login(function(response) {
    //do whatever you need to do after a (un)successfull login         
}, { scope: 'user_likes' });

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

string = input("Enter the string : ")

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

OUTPUT : -

Enter the string : viral

The string length is : 5

What you want is lazy iteration over an object or array. This is not possible in ES5 (thus not possible in node.js). We will get this eventually.

The only solution is finding a node module that extends V8 to implement iterators (and probably generators). I couldn't find any implementation. You can look at the spidermonkey source code and try writing it in C++ as a V8 extension.

You could try the following, however it will also load all the keys into memory

Object.keys(o).forEach(function(key) {
  var val = o[key];
  logic();
});

However since Object.keys is a native method it may allow for better optimisation.

Benchmark

As you can see Object.keys is significantly faster. Whether the actual memory storage is more optimum is a different matter.

var async = {};
async.forEach = function(o, cb) {
  var counter = 0,
    keys = Object.keys(o),
    len = keys.length;
  var next = function() {
    if (counter < len) cb(o[keys[counter++]], next);
  };
  next();
};

async.forEach(obj, function(val, next) {
  // do things
  setTimeout(next, 100);
});

Another solution:

select * from traintable
where (train, time) in (select train, max(time) from traintable group by train);

Background Image from API in swift 4 (with Kingfisher) :

import UIKit
import Kingfisher

extension UIView {

func addBackgroundImage(imgUrl: String, placeHolder: String){
    let backgroundImage = UIImageView(frame: self.bounds)
    backgroundImage.kf.setImage(with: URL(string: imgUrl), placeholder: UIImage(named: placeHolder))
    backgroundImage.contentMode = UIViewContentMode.scaleAspectFill
    self.insertSubview(backgroundImage, at: 0)

}
}

Usage:

someview.addBackgroundImage(imgUrl: "yourImgUrl", placeHolder: "placeHolderName")

asp:HiddenField as:

<asp:HiddenField runat="server" ID="hfProduct" ClientIDMode="Static" />

js code:

$("#hfProduct").val("test")

and the code behind:

hfProduct.Value.ToString();

You can do something like this:

<%!
String myMethod(String input) {
    return "test " + input;
}
%>

<%= myMethod("1 2 3") %>

This will output test 1 2 3 to the page.

For others facing this issue in Eclipse even with path set to JDK correctly, you need to remove the other JREs from Installed JREs.

Go to Window -> Preferences -> Java -> Installed JREs

Select unused JREs individually and Remove

It worked for me.

Get all views from any type of layout

public List<View> getAllViews(ViewGroup layout){
        List<View> views = new ArrayList<>();
        for(int i =0; i< layout.getChildCount(); i++){
            views.add(layout.getChildAt(i));
        }
        return views;
}

Get all TextView from any type of layout

public List<TextView> getAllTextViews(ViewGroup layout){
        List<TextView> views = new ArrayList<>();
        for(int i =0; i< layout.getChildCount(); i++){
            View v =layout.getChildAt(i);
            if(v instanceof TextView){
                views.add((TextView)v);
            }
        }
        return views;
}

Best solution is to use the extension we created at CodePath called SmartFragmentStatePagerAdapter. Following that guide, this makes retrieving fragments and the currently selected fragment from a ViewPager significantly easier. It also does a better job of managing the memory of the fragments embedded within the adapter.

It is important to run your mongod command and keep the server running. If not, you will still be seeing this error.

I attach you my code:

const mongodb = require('mongodb')
const MongoClient = mongodb.MongoClient

const connectionURL = 'mongodb://127.0.0.1:27017'
const databaseName = 'task-manager'

MongoClient.connect(connectionURL, {useNewUrlParser: true, useUnifiedTopology: true}, (error, client) => {
    if(error) {
        return console.log('Error connecting to the server.')
    }

    console.log('Succesfully connected.')
})

Floating Point Exception happens because of an unexpected infinity or NaN. You can track that using gdb, which allows you to see what is going on inside your C program while it runs. For more details: https://www.cs.swarthmore.edu/~newhall/unixhelp/howto_gdb.php

In a nutshell, these commands might be useful...

gcc -g myprog.c

gdb a.out

gdb core a.out

ddd a.out

Following will return true when checkbox is checked and false when not.

$(this).is(":checked")

Replace $(this) with the variable you want to check.

And used in a condition:

if ($(this).is(":checked")) {
  // do something
}

I suggest to follow the documentation and create ~/.pip/pip.conf file. Note in the documentation there are missing specified header directory, which leads to following error:

error: install-base or install-platbase supplied, but installation scheme is incomplete

The full working content of conf file is:

[install]
install-base=$HOME
install-purelib=python/lib
install-platlib=python/lib.$PLAT
install-scripts=python/scripts
install-headers=python/include
install-data=python/data

Unfortunatelly I can install, but when try to uninstall pip tells me there is no such package for uninstallation process.... so something is still wrong but the package goes to its predefined location.

SELECT 
employees.id, 
CONCAT(employees.f_name," ",employees.l_name) AS   'Full Name', genders.gender_name AS 'Sex', 
depts.dept_name AS 'Team Name', 
pay_grades.pay_grade_name AS 'Band', 
designations.designation_name AS 'Role' 
FROM employees 
LEFT JOIN genders ON employees.gender_id = genders.id 
LEFT JOIN depts ON employees.dept_id = depts.id 
LEFT JOIN pay_grades ON employees.pay_grade_id = pay_grades.id 
LEFT JOIN designations ON employees.designation_id = designations.id 
ORDER BY employees.id;

You can JOIN multiple TABLES like this example above.

Try

   sSource = sSource.replaceAll("\\\\", "");

Edit : Ok even in stackoverflow there is backslash escape... You need to have four backslashes in your replaceAll first String argument...

The reason of this is because backslash is considered as an escape character for special characters (like \n for instance).
Moreover replaceAll first arg is a regular expression that also use backslash as escape sequence.
So for the regular expression you need to pass 2 backslash. To pass those two backslashes by a java String to the replaceAll, you also need to escape both backslashes.
That drives you to have four backslashes for your expression! That's the beauty of regex in java ;)

There are lots of great answers which discuss differences in the use cases for each function. None of the answer discuss the differences in performance. That is reasonable cause various functions expects various input and produces various output, yet most of them have a general common objective to evaluate by series/groups. My answer is going to focus on performance. Due to above the input creation from the vectors is included in the timing, also the apply function is not measured.

I have tested two different functions sum and length at once. Volume tested is 50M on input and 50K on output. I have also included two currently popular packages which were not widely used at the time when question was asked, data.table and dplyr. Both are definitely worth to look if you are aiming for good performance.

library(dplyr)
library(data.table)
set.seed(123)
n = 5e7
k = 5e5
x = runif(n)
grp = sample(k, n, TRUE)

timing = list()

# sapply
timing[["sapply"]] = system.time({
    lt = split(x, grp)
    r.sapply = sapply(lt, function(x) list(sum(x), length(x)), simplify = FALSE)
})

# lapply
timing[["lapply"]] = system.time({
    lt = split(x, grp)
    r.lapply = lapply(lt, function(x) list(sum(x), length(x)))
})

# tapply
timing[["tapply"]] = system.time(
    r.tapply <- tapply(x, list(grp), function(x) list(sum(x), length(x)))
)

# by
timing[["by"]] = system.time(
    r.by <- by(x, list(grp), function(x) list(sum(x), length(x)), simplify = FALSE)
)

# aggregate
timing[["aggregate"]] = system.time(
    r.aggregate <- aggregate(x, list(grp), function(x) list(sum(x), length(x)), simplify = FALSE)
)

# dplyr
timing[["dplyr"]] = system.time({
    df = data_frame(x, grp)
    r.dplyr = summarise(group_by(df, grp), sum(x), n())
})

# data.table
timing[["data.table"]] = system.time({
    dt = setnames(setDT(list(x, grp)), c("x","grp"))
    r.data.table = dt[, .(sum(x), .N), grp]
})

# all output size match to group count
sapply(list(sapply=r.sapply, lapply=r.lapply, tapply=r.tapply, by=r.by, aggregate=r.aggregate, dplyr=r.dplyr, data.table=r.data.table), 
       function(x) (if(is.data.frame(x)) nrow else length)(x)==k)
#    sapply     lapply     tapply         by  aggregate      dplyr data.table 
#      TRUE       TRUE       TRUE       TRUE       TRUE       TRUE       TRUE 

# print timings
as.data.table(sapply(timing, `[[`, "elapsed"), keep.rownames = TRUE
              )[,.(fun = V1, elapsed = V2)
                ][order(-elapsed)]
#          fun elapsed
#1:  aggregate 109.139
#2:         by  25.738
#3:      dplyr  18.978
#4:     tapply  17.006
#5:     lapply  11.524
#6:     sapply  11.326
#7: data.table   2.686

In Swift 3, its much simpler

let stringA = "Terms and Conditions"
let stringB = "Please read the instructions"

yourlabel.text =  "\(stringA)\n\(stringB)"

or if you are using a textView

yourtextView.text =  "\(stringA)\n\(stringB)"

If you wanted just a Date, you can do Date.strptime(invoice.date.to_s, '%s') where invoice.date comes in the form of anFixnum and then converted to a String.

I prefer to use

#define FALSE (0!=0) 
#define TRUE  (0==0)

or directly in the code

if (flag == (0==0)) { ... }

The compiler will take care of that. I use a lot of languages and having to remember that FALSE is 0 bothers me a lot; but if I have to, I usually think about that string loop

do { ... } while (*ptr);

and that leads me to see that FALSE is 0

You'll get that error once your numbers are greater than sys.maxsize:

>>> p = [sys.maxsize]
>>> preds[0] = p
>>> p = [sys.maxsize+1]
>>> preds[0] = p
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
OverflowError: Python int too large to convert to C long

You can confirm this by checking:

>>> import sys
>>> sys.maxsize
2147483647

To take numbers with larger precision, don't pass an int type which uses a bounded C integer behind the scenes. Use the default float:

>>> preds = np.zeros((1, 3))

Modal In Out Effect with Animate.css and jquery Very easy and short code.

In HTML:

<div class="modal fade" id="DirectorModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
    <div class="modal-dialog bounceInDown animated"><!-- Add here Modal COME Effect "Animate.css" -->
        <div class="modal-content">
         <div class="modal-header">
          <button type="button" class="close" data-dismiss="modal">&times;</button>
           <h4 class="modal-title">Modal Header</h4>
          </div>
          <div class="modal-body">
          </div>
        </div>
    </div>
</div>

this bellow jquery code i got from: https://codepen.io/nhembram/pen/PzyYLL

i am modify this for regular use.

jquery code:

<script>
    $(document).ready(function () {
    // BS MODAL OPEN CLOSE EFFECT  ---------------------------------
        var timeoutHandler = null;
        $('.modal').on('hide.bs.modal', function (e) {
            var anim = $('.modal-dialog').removeClass('bounceInDown').addClass('fadeOutDownBig'); // Model Come class Remove & Out effect class add
            if (timeoutHandler) clearTimeout(timeoutHandler);
            timeoutHandler = setTimeout(function() {
                $('.modal-dialog').removeClass('fadeOutDownBig').addClass('bounceInDown'); // Model Out class Remove & Come effect class add
            }, 500); // some delay for complete Animation
        });
    });
    </script>

The problem is that you aren't correctly escaping the input string, try:

echo "\"member\":\"time\"" | grep -e "member\""

Alternatively, you can use unescaped double quotes within single quotes:

echo '"member":"time"' | grep -e 'member"'

It's a matter of preference which you find clearer, although the second approach prevents you from nesting your command within another set of single quotes (e.g. ssh 'cmd').

Make sure that you are building your web app as "Any CPU". Right click your web project --> Properties --> Build --> and look for the "Platform Target". Choose "Any CPU" or play around with it.

Hope this helps!

I had same problem to connect mongodb after install using brew on macOS.

The problem was also mongod.lock but before i had mongodb 3.6 installed and database directory was /usr/local/var/mongodb and it have old files and mongod.lock

Simple i moved my old database files to different folder and removed everything from /usr/local/var/mongodb

Then restarted :

brew services restart mongodb

And it's working fine now.

Why not try find /usr/include/X11 -name Xlib.h

If there is a hit, you have Xlib.h

If not install it using sudo apt-get install libx11-dev

and you are good to go :)

Something like:

DateTime today = DateTime.Today;
DateTime endOfMonth = new DateTime(today.Year, today.Month, 1).AddMonths(1).AddDays(-1);

Which is to say that you get the first day of next month, then subtract a day. The framework code will handle month length, leap years and such things.

1. Create a subclass of Application, for instance public class App extends Application {
2. Set the android:name attribute of your <application> tag in the AndroidManifest.xml to point to your new class, e.g. android:name=".App"
3. In the onCreate() method of your app instance, save your context (e.g. this) to a static field named mContext and create a static method that returns this field, e.g. getContext():

This is how it should look:

public class App extends Application{

    private static Context mContext;

    @Override
    public void onCreate() {
        super.onCreate();
        mContext = this;
    }

    public static Context getContext(){
        return mContext;
    }
}

Now you can use: App.getContext() whenever you want to get a context, and then getResources() (or App.getContext().getResources()).

On Windows 7 for example, the following set of commands/operations could be used.

Create an personal environment variable, double backslashes are mandatory:

• Variable name: %NPM_HOME%
• Variable value: C:\\SomeFolder\\SubFolder\\

Now, set the config values to the new folders (examplary file names):

• Set the npm folder

npm config set prefix "%NPM_HOME%\\npm"

• Set the npm-cache folder

npm config set cache "%NPM_HOME%\\npm-cache"

• Set the npm temporary folder

npm config set tmp "%NPM_HOME%\\temp"

Optionally, you can purge the contents of the original folders before the config is changed.

• Delete the npm-cache npm cache clear

• List the npm modules npm -g ls

• Delete the npm modules npm -g rm name_of_package1 name_of_package2

For a Table:

SELECT 
  TABLE_NAME,COLUMN_NAME,CONSTRAINT_NAME, REFERENCED_TABLE_NAME,REFERENCED_COLUMN_NAME
FROM
  INFORMATION_SCHEMA.KEY_COLUMN_USAGE
WHERE
  REFERENCED_TABLE_SCHEMA = '<database>' AND
  REFERENCED_TABLE_NAME = '<table>';

For a Column:

SELECT 
  TABLE_NAME,COLUMN_NAME,CONSTRAINT_NAME, REFERENCED_TABLE_NAME,REFERENCED_COLUMN_NAME
FROM
  INFORMATION_SCHEMA.KEY_COLUMN_USAGE
WHERE
  REFERENCED_TABLE_SCHEMA = '<database>' AND
  REFERENCED_TABLE_NAME = '<table>' AND
  REFERENCED_COLUMN_NAME = '<column>';

Basically, we changed REFERENCED_TABLE_NAME with REFERENCED_COLUMN_NAME in the where clause.

If possible use Visual Studio. The Microsoft SQL Server Data Tools (SSDT) bring a built in functionality for this since the March 2014 release:

1. Open Visual Studio
2. Open "View" ? "SQL Server Object Explorer"
3. Add a connection to your Server
4. Expand the relevant database
5. Expand the "Tables" folder
6. Right click on relevant table
7. Select "View Data" from context menu
8. In the new window, viewing the data use the "Sort and filter dataset" functionality in the tool bar to apply your filter. Note that this functionality is limited and you can't write explicit SQL queries.
9. After you have applied your filter and see only the data you want, click on "Script" or "Script to file" in the tool bar
10. Voilà - Here you have your insert script for your filtered data

Note: Be careful, the "View Data" window is just like SSMS "Edit Top 200 Rows"- you can edit data right away

(Tested with Visual Studio 2015 with Microsoft SQL Server Data Tools (SSDT) Version 14.0.60812.0 and Microsoft SQL Server 2012)

A . in regex is a metacharacter, it is used to match any character. To match a literal dot, you need to escape it, so \.

I think this is not the best way, but in my cases other methods did not work.

stylesheet = document.styleSheets[0]
stylesheet.insertRule(".have-border { border: 1px solid black;}", 0);

Example from https://www.w3.org/wiki/Dynamic_style_-_manipulating_CSS_with_JavaScript

DECLARE   @UserOptions TABLE(SetOption varchar(100), Value varchar(100))
DECLARE   @IsolationLevel varchar(100)

INSERT    @UserOptions
EXEC('DBCC USEROPTIONS WITH NO_INFOMSGS')

SELECT    @IsolationLevel = Value
FROM      @UserOptions
WHERE     SetOption = 'isolation level'

-- Do whatever you want with the variable here...  
PRINT     @IsolationLevel
