Programs & Examples On #Export to excel

You need to set index=False in to_excel in order for it to not write the index column out, this semantic is followed in other Pandas IO tools, see http://pandas.pydata.org/pandas-docs/stable/generated/pandas.DataFrame.to_excel.html and http://pandas.pydata.org/pandas-docs/stable/io.html

It is possible to use the old Excel 2003 XML format (before OpenXML) to create a string that contains your desired XML, then on the client side you could use a data URI to open the file using the XSL mime type, or send the file to the client using the Excel mimetype "Content-Type: application/vnd.ms-excel" from the server side.

1. Open Excel and create a worksheet with your desired formatting and colors.
2. Save the Excel workbook as "XML Spreadsheet 2003 (*.xml)"
3. Open the resulting file in a text editor like notepad and copy the value into a string in your application
4. Assuming you use the client side approach with a data uri the code would look like this:

   
   <script type="text/javascript">
   var worksheet_template = '<?xml version="1.0"?><ss:Workbook xmlns:ss="urn:schemas-microsoft-com:office:spreadsheet">'+
                '<ss:Styles><ss:Style ss:ID="1"><ss:Font ss:Bold="1"/></ss:Style></ss:Styles><ss:Worksheet ss:Name="Sheet1">'+
                '<ss:Table>{{ROWS}}</ss:Table></ss:Worksheet></ss:Workbook>';
   var row_template = '<ss:Row ss:StyleID="1"><ss:Cell><ss:Data ss:Type="String">{{name}}</ss:Data></ss:Cell></ss:Row>';
   </script>
   
   

5. Then you can use string replace to create a collection of rows to be inserted into your worksheet template

   
   <script type="text/javascript">
   var rows = document.getElementById("my-table").getElementsByTagName('tr'),
     row_data = '';
   for (var i = 0, length = rows.length; i < length; ++i) {
   row_data += row_template.replace('{{name}}', rows[i].getElementsByTagName('td')[0].innerHTML);
   }
   </script>
   
   

6. Once you have the information collected, create the final string and open a new window using the data URI

   
   <script type="text/javascript">
   var worksheet = worksheet_template.replace('{{ROWS}}', row_data);
   
   window.open('data:application/vnd.ms-excel,'+worksheet);
   </script>
   
   

It is worth noting that older browsers do not support the data URI scheme, so you may need to produce the file server side for those browser that do not support it.

You may also need to perform base64 encoding on the data URI content, which may require a js library, as well as adding the string ';base64' after the mime type in the data URI.

At least in SQL Server 2012, you can right click in the query window and select Query Options. From there you can select Include Headers for grid and/or text and have the Save As work the way you want it without restarting SSMS.

You'll still need to change it in Tools->Options in the menu bar to have new query windows use those settings by default.

For anyone coming here looking for how to do this in C#, I have tried the following method and had success in dotnet core 2.0.3 and entity framework core 2.0.3

First create your model class.

public class User
{  
    public string Name { get; set; }  
    public int Address { get; set; }  
    public int ZIP { get; set; }  
    public string Gender { get; set; }  
} 

Then install EPPlus Nuget package. (I used version 4.0.5, probably will work for other versions as well.)

Install-Package EPPlus -Version 4.0.5

The create ExcelExportHelper class, which will contain the logic to convert dataset to Excel rows. This class do not have dependencies with your model class or dataset.

public class ExcelExportHelper
    {
        public static string ExcelContentType
        {
            get
            { return "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"; }
        }

        public static DataTable ListToDataTable<T>(List<T> data)
        {
            PropertyDescriptorCollection properties = TypeDescriptor.GetProperties(typeof(T));
            DataTable dataTable = new DataTable();

            for (int i = 0; i < properties.Count; i++)
            {
                PropertyDescriptor property = properties[i];
                dataTable.Columns.Add(property.Name, Nullable.GetUnderlyingType(property.PropertyType) ?? property.PropertyType);
            }

            object[] values = new object[properties.Count];
            foreach (T item in data)
            {
                for (int i = 0; i < values.Length; i++)
                {
                    values[i] = properties[i].GetValue(item);
                }

                dataTable.Rows.Add(values);
            }
            return dataTable;
        }

                if (showSrNo)
                {
                    DataColumn dataColumn = dataTable.Columns.Add("#", typeof(int));

                        item[0] = index;
                        index++;
                    }
                }


                // add the content into the Excel file  
                workSheet.Cells["A" + startRowFrom].LoadFromDataTable(dataTable, true);

                // autofit width of cells with small content  
                int columnIndex = 1;
                foreach (DataColumn column in dataTable.Columns)

                }

                // format cells - add borders  
                using (ExcelRange r = workSheet.Cells[startRowFrom + 1, 1, startRowFrom + dataTable.Rows.Count, dataTable.Columns.Count])
                {
                    r.Style.Border.Top.Style = ExcelBorderStyle.Thin;
                    r.Style.Border.Bottom.Style = ExcelBorderStyle.Thin;
                    r.Style.Border.Left.Style = ExcelBorderStyle.Thin;
                    r.Style.Border.Right.Style = ExcelBorderStyle.Thin;

                // removed ignored columns  
                for (int i = dataTable.Columns.Count - 1; i >= 0; i--)
                {
                    if (i == 0 && showSrNo)
                    {
                        continue;

                    if (!columnsToTake.Contains(dataTable.Columns[i].ColumnName))
                    {
                        workSheet.DeleteColumn(i + 1);
                    }
                }

                if (!String.IsNullOrEmpty(heading))
                {
                    workSheet.Cells["A1"].Value = heading;
                   // workSheet.Cells["A1"].Style.Font.Size = 20;

                    workSheet.InsertColumn(1, 1);
                    workSheet.InsertRow(1, 1);
                    workSheet.Column(1).Width = 10;
                }

                result = package.GetAsByteArray();
            }

            return result;
        }

        public static byte[] ExportExcel<T>(List<T> data, string Heading = "", bool showSlno = false, params string[] ColumnsToTake)
        {
            return ExportExcel(ListToDataTable<T>(data), Heading, showSlno, ColumnsToTake);
        }
    }

Now add this method where you want to generate the excel file, probably for a method in the controller. You can pass parameters for your stored procedure as well. Note that the return type of the method is FileContentResult. Whatever query you execute, important thing is you must have the results in a List.

[HttpPost]
public async Task<FileContentResult> Create([Bind("Id,StartDate,EndDate")] GetReport getReport)
{
    DateTime startDate = getReport.StartDate;
    DateTime endDate = getReport.EndDate;

    // call the stored procedure and store dataset in a List.
    List<User> users = _context.Reports.FromSql("exec dbo.SP_GetEmpReport @start={0}, @end={1}", startDate, endDate).ToList();
    //set custome column names
    string[] columns = { "Name", "Address", "ZIP", "Gender"};
    byte[] filecontent = ExcelExportHelper.ExportExcel(users, "Users", true, columns);
    // set file name.
    return File(filecontent, ExcelExportHelper.ExcelContentType, "Report.xlsx"); 
}

Lawrence has given you a good answer. But if you want more control over what gets exported to where in Excel see Modules: Sample Excel Automation - cell by cell which is slow and Modules: Transferring Records to Excel with Automation You can do things such as export the recordset starting in row 2 and insert custom text in row 1. As well as any custom formatting required.

You can call helper class in any controller

//view 
 @Html.ActionLink("Export to Excel", "Excel")

//controller Action
public void Excel()
{
    var model = db.GetModel()

    Export export = new Export();
    export.ToExcel(Response, model);
}

//helper class
public class Export
{        public void ToExcel(HttpResponseBase Response, object clientsList)
    {
        var grid = new System.Web.UI.WebControls.GridView();
        grid.DataSource = clientsList;
        grid.DataBind();
        Response.ClearContent();
        Response.AddHeader("content-disposition", "attachment; filename=FileName.xls");
        Response.ContentType = "application/excel";
        StringWriter sw = new StringWriter();
        HtmlTextWriter htw = new HtmlTextWriter(sw);

        grid.RenderControl(htw);
        Response.Write(sw.ToString());
        Response.End();
    }
}

excel4node is a maintained, native Excel file creator built from the official specification. It's similar to, but more maintained than mxexcel-builder mentioned in the other answer.

// Require library
var excel = require('excel4node');

// Create a new instance of a Workbook class
var workbook = new excel.Workbook();

// Add Worksheets to the workbook
var worksheet = workbook.addWorksheet('Sheet 1');
var worksheet2 = workbook.addWorksheet('Sheet 2');

// Create a reusable style
var style = workbook.createStyle({
  font: {
    color: '#FF0800',
    size: 12
  },
  numberFormat: '$#,##0.00; ($#,##0.00); -'
});

// Set value of cell A1 to 100 as a number type styled with paramaters of style
worksheet.cell(1,1).number(100).style(style);

// Set value of cell B1 to 300 as a number type styled with paramaters of style
worksheet.cell(1,2).number(200).style(style);

// Set value of cell C1 to a formula styled with paramaters of style
worksheet.cell(1,3).formula('A1 + B1').style(style);

// Set value of cell A2 to 'string' styled with paramaters of style
worksheet.cell(2,1).string('string').style(style);

// Set value of cell A3 to true as a boolean type styled with paramaters of style but with an adjustment to the font size.
worksheet.cell(3,1).bool(true).style(style).style({font: {size: 14}});

workbook.write('Excel.xlsx');

I asume you have connected to your database already.

$sql = "SELECT * FROM my_table";
$result = mysql_query($sql);

$row = 1; // 1-based index
while($row_data = mysql_fetch_assoc($result)) {
    $col = 0;
    foreach($row_data as $key=>$value) {
        $objPHPExcel->getActiveSheet()->setCellValueByColumnAndRow($col, $row, $value);
        $col++;
    }
    $row++;
}

Use your WorkSheet.Columns.NumberFormat, and set it to string "@", here is the sample:

Excel._Worksheet workSheet = (Excel._Worksheet)_Excel.Worksheets.Add();
//set columns format to text format
workSheet.Columns.NumberFormat = "@";

Note: this text format will apply for your hole excel sheet!

If you want a particular column to apply the text format, for example, the first column, you can do this:

workSheet.Columns[0].NumberFormat = "@";

or this will apply the specified range of woorkSheet to text format:

workSheet.get_Range("A1", "D1").NumberFormat = "@";

CSV export is simple, easy to implement, and fast. There is one potential issue worth noting, though. Excel (up to 2007) does not preserve leading zeros in CSV files. This will garble ZIP codes, product ids, and other textual data containing numeric values. There is one trick that will make Excel import the values correctly (using delimiters and prefix values with the = sign, if I remember correctly, e.g. ..,="02052",...). If you have users who will do post-processing tasks with the CSV, they need to be aware that they need to change the format to XLS and not save the file back to CSV. If they do, leading zeros will be lost for good.

If you want to convert CSV to Excel without Excel being installed, you can use the great .NET library EPPlus (under LGPL license) to create and modify Excel Sheets and also convert CSV to Excel really fast!

Preparation

1. Download the latest stable EPPlus version
2. Extract EPPlus to your preferred location (e.g. to $HOME\Documents\WindowsPowerShell\Modules\EPPlus)
3. Right Click EPPlus.dll, select Properties and at the bottom of the General Tab click "Unblock" to allow loading of this dll. If you don't have the rights to do this, try [Reflection.Assembly]::UnsafeLoadFrom($DLLPath) | Out-Null

My 2 cents - you don't need to store the excel as a physical file on the server - instead, store it in the (Session) Cache. Use a uniquely generated name for your Cache variable (that stores that excel file) - this will be the return of your (initial) ajax call. This way you don't have to deal with file access issues, managing (deleting) the files when not needed, etc. and, having the file in the Cache, is faster to retrieve it.

I was able to get this done following more complex instructions suggested by Valentino Vranken and rao , but here is a more simple approach , for a more simple report . This will put each table on a separate sheet and name them in Excel . It doesn't seem to have an effect on other exports like PDF and Word .

First in the Tablix Properties of of your tables under General , check either Add a page break before or after , this separates the report into sheets .

Then in each table , click the table , then in the Grouping view , on the Row Groups side , select the parent group or the default row group and then in the Properties view under Group -> PageBreak set BreakLocation to None and PageName to the sheet's name .

Try regexp currency with jQuery (no plugin):

$(document).ready(function(){_x000D_
  $('#test').click(function() {_x000D_
    TESTCURRENCY = $('#value').val().toString().match(/(?=[\s\d])(?:\s\.|\d+(?:[.]\d+)*)/gmi);_x000D_
    if (TESTCURRENCY.length <= 1) {_x000D_
      $('#valueshow').val(_x000D_
        parseFloat(TESTCURRENCY.toString().match(/^\d+(?:\.\d{0,2})?/))_x000D_
      );_x000D_
    } else {_x000D_
      $('#valueshow').val('Invalid a value!');_x000D_
    }_x000D_
  });_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>_x000D_
<input type="text" value="12345.67890" id="value">_x000D_
<input type="button" id="test" value="CLICK">_x000D_
<input type="text" value="" id="valueshow">

Edit: New check a value to valid/invalid

The .join() method has a parameter for the separator string. If you want it to be empty instead of the default comma, use

arr.join("");

Float elements will be rendered at the line they are normally in the layout. To fix this, you have two choices:

Move the header and the p after the login box:

<div class='container'>
    <div class='hero-unit'>

        <div id='login-box' class='pull-right control-group'>
            <div class='clearfix'>
                <input type='text' placeholder='Username' />
            </div>
            <div class='clearfix'>

If you want to disable this warning it is important to know that there are two related warning parameters in GCC and Clang: GCC Compiler options -wno-four-char-constants and -wno-multichar

If that question is connected to your other Hudson questions use the command they provide. This way with XML from the command line:

$ curl -X POST -d '<run>...</run>' \
http://user:pass@myhost:myport/path/of/url

You need to change it a little bit to read from a file:

 $ curl -X POST -d @myfilename http://user:pass@myhost:myport/path/of/url

Read the manpage. following an abstract for -d Parameter.

-d/--data

(HTTP) Sends the specified data in a POST request to the HTTP server, in the same way that a browser does when a user has filled in an HTML form and presses the submit button. This will cause curl to pass the data to the server using the content-type application/x-www-form-urlencoded. Compare to -F/--form.

-d/--data is the same as --data-ascii. To post data purely binary, you should instead use the --data-binary option. To URL-encode the value of a form field you may use --data-urlencode.

If any of these options is used more than once on the same command line, the data pieces specified will be merged together with a separating &-symbol. Thus, using '-d name=daniel -d skill=lousy' would generate a post chunk that looks like 'name=daniel&skill=lousy'.

If you start the data with the letter @, the rest should be a file name to read the data from, or - if you want curl to read the data from stdin. The contents of the file must already be URL-encoded. Multiple files can also be specified. Posting data from a file named 'foobar' would thus be done with --data @foobar.

echo 'hollow world' . PHP_EOL;

Use the constant PHP_EOL then it is OS independent too.

As a sidenote to @Navaneethan 's answer, Jinja2 is able to do "regular" item selections for the list and the dictionary, given we know the key of the dictionary, or the locations of items in the list.

Data:

parent_dict = [{'A':'val1','B':'val2', 'content': [["1.1", "2.2"]]},{'A':'val3','B':'val4', 'content': [["3.3", "4.4"]]}]

in Jinja2 iteration:

{% for dict_item in parent_dict %}
   This example has {{dict_item['A']}} and {{dict_item['B']}}:
       with the content --
       {% for item in dict_item['content'] %}{{item[0]}} and {{item[1]}}{% endfor %}.
{% endfor %}

The rendered output:

This example has val1 and val2:
    with the content --
    1.1 and 2.2.

This example has val3 and val4:
   with the content --
   3.3 and 4.4.

1. You seem to be including one C file from anther. #include should normally be used with header files only.

2. Within the definition of struct ast_node you refer to struct AST_NODE, which doesn't exist. C is case-sensitive.

Try this:

replace(ltrim(replace(@str, '0', ' ')), ' ', '0')

Use np.mat(x) * np.mat(y), that'll work.

Good morning,

I know this is an old thread but I just ran across it while looking for a similar problem - script was running successfully but not doing its work. I can't find the post that helped me but my issue was that I was running the script as the domain admin. When I followed the suggestion of the post and added the domain admin to the local administrator's group it worked. I hope this helps others with the same issue I had.

Joe

I think you can't increase the time for query execution, but you need to increase the timeout for the request.

Execution Timeout Specifies the maximum number of seconds that a request is allowed to execute before being automatically shut down by ASP.NET. (Default time is 110 seconds.)

For Details, please have a look at https://msdn.microsoft.com/en-us/library/e1f13641%28v=vs.100%29.aspx

You can do in the web.config. e.g

<httpRuntime maxRequestLength="2097152" executionTimeout="600" />

You can target the first child element with just using CSS selector with jQuery:

$(this).children('img:nth-child(1)');

If you want to target the second child element just change 1 to 2:

$(this).children('img:nth-child(2)');

and so on..

if you want to target more elements, you can use a for loop:

for (i = 1; i <= $(this).children().length; i++) {
    let childImg =  $(this).children("img:nth-child("+ i +")");
    // Do stuff...
}

use the function norm in scipy.linalg (or numpy.linalg)

>>> from scipy import linalg as LA
>>> a = 10*NP.random.randn(6)
>>> a
  array([  9.62141594,   1.29279592,   4.80091404,  -2.93714318,
          17.06608678, -11.34617065])
>>> LA.norm(a)
    23.36461979210312

>>> # compare with OP's function:
>>> import math
>>> mag = lambda x : math.sqrt(sum(i**2 for i in x))
>>> mag(a)
     23.36461979210312

I have read the many comments on this page that complain that using a dom parser is unnecessary overhead. Well, it may be more expensive than a mere regex call, but the OP has stated that there is no control over the order of the attributes in the img tags. This fact leads to unnecessary regex pattern convolution. Beyond that, using a dom parser provides the additional benefits of readability, maintainability, and dom-awareness (regex is not dom-aware).

I love regex and I answer lots of regex questions, but when dealing with valid HTML there is seldom a good reason to regex over a parser.

In the demonstration below, see how easy and clean DOMDocument handles img tag attributes in any order with a mixture of quoting (and no quoting at all). Also notice that tags without a targeted attribute are not disruptive at all -- an empty string is provided as a value.

Code: (Demo)

$test = <<<HTML
<img src="/image/fluffybunny.jpg" title="Harvey the bunny" alt="a cute little fluffy bunny" />
<img src='/image/pricklycactus.jpg' title='Roger the cactus' alt='a big green prickly cactus' />
<p>This is irrelevant text.</p>
<img alt="an annoying white cockatoo" title="Polly the cockatoo" src="/image/noisycockatoo.jpg">
<img title=something src=somethingelse>
HTML;

libxml_use_internal_errors(true);  // silences/forgives complaints from the parser (remove to see what is generated)
$dom = new DOMDocument();
$dom->loadHTML($test);
foreach ($dom->getElementsByTagName('img') as $i => $img) {
    echo "IMG#{$i}:\n";
    echo "\tsrc = " , $img->getAttribute('src') , "\n";
    echo "\ttitle = " , $img->getAttribute('title') , "\n";
    echo "\talt = " , $img->getAttribute('alt') , "\n";
    echo "---\n";
}

Output:

IMG#0:
    src = /image/fluffybunny.jpg
    title = Harvey the bunny
    alt = a cute little fluffy bunny
---
IMG#1:
    src = /image/pricklycactus.jpg
    title = Roger the cactus
    alt = a big green prickly cactus
---
IMG#2:
    src = /image/noisycockatoo.jpg
    title = Polly the cockatoo
    alt = an annoying white cockatoo
---
IMG#3:
    src = somethingelse
    title = something
    alt = 
---

Using this technique in professional code will leave you with a clean script, fewer hiccups to contend with, and fewer colleagues that wish you worked somewhere else.

Please see the below approaches,

Approach 1: Using INFORMATION_SCHEMA.TABLES view

We can write a query like below to check if a Customers Table exists in the current database.

IF EXISTS (SELECT * FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_NAME = N'Customers')
BEGIN
    PRINT 'Table Exists'
END

Approach 2: Using OBJECT_ID() function

We can use OBJECT_ID() function like below to check if a Customers Table exists in the current database.

IF OBJECT_ID(N'dbo.Customers', N'U') IS NOT NULL
BEGIN
    PRINT 'Table Exists'
END

Approach 3: Using sys.Objects Catalog View

We can use the Sys.Objects catalog view to check the existence of the Table as shown below:

IF EXISTS(SELECT 1 FROM sys.Objects WHERE  Object_id = OBJECT_ID(N'dbo.Customers') AND Type = N'U')
BEGIN
   PRINT 'Table Exists'
END

Approach 4: Using sys.Tables Catalog View

We can use the Sys.Tables catalog view to check the existence of the Table as shown below:

 IF EXISTS(SELECT 1 FROM sys.Tables WHERE  Name = N'Customers' AND Type = N'U')
 BEGIN
      PRINT 'Table Exists'
 END

Approach 5: Avoid Using sys.sysobjects System table

We should avoid using sys.sysobjects System Table directly, direct access to it will be deprecated in some future versions of the Sql Server. As per Microsoft BOL link, Microsoft is suggesting to use the catalog views sys.objects/sys.tables instead of sys.sysobjects system table directly.

  IF EXISTS(SELECT name FROM sys.sysobjects WHERE Name = N'Customers' AND xtype = N'U')
  BEGIN
     PRINT 'Table Exists'
  END

referred from: http://sqlhints.com/2014/04/13/how-to-check-if-a-table-exists-in-sql-server/

You need to change public void klik(PaintEventArgs pea, EventArgs e) to public void klik(object sender, System.EventArgs e) because there is no Click event handler with parameters PaintEventArgs pea, EventArgs e.

You return four variables s1,s2,s3,s4 and receive them using a single variable obj. This is what is called a tuple, obj is associated with 4 values, the values of s1,s2,s3,s4. So, use index as you use in a list to get the value you want, in order.

obj=list_benefits()
print obj[0] + " is a benefit of functions!"
print obj[1] + " is a benefit of functions!"
print obj[2] + " is a benefit of functions!"
print obj[3] + " is a benefit of functions!"

If you want to automatically/periodically clean up exited containers and remove images and volumes that aren't in use by a running container you can download the Docker image meltwater/docker-cleanup.

That way you don't need to go clean it up by hand.

Just run:

docker run -d -v /var/run/docker.sock:/var/run/docker.sock:rw  -v /var/lib/docker:/var/lib/docker:rw --restart=unless-stopped meltwater/docker-cleanup:latest

It will run every 30 minutes (or however long you set it using DELAY_TIME=1800 option) and clean up exited containers and images.

More details: https://github.com/meltwater/docker-cleanup/blob/master/README.md

Very useful post, to add NSDictionary support as well one small change

static inline BOOL isEmpty(id thing) {
    return thing == nil
    || [thing isKindOfClass:[NSNull class]]
    || ([thing respondsToSelector:@selector(length)]
        && ![thing respondsToSelector:@selector(count)]
        && [(NSData *)thing length] == 0)
    || ([thing respondsToSelector:@selector(count)]
        && [thing count] == 0);
}

For those using Sass, I have written a mixin for this purpose:

@mixin addSeparator($element, $separator, $padding) {
    #{$element+'+'+$element}:before {
        content: $separator;
        padding: 0 $padding;
    }
}

Example:

@include addSeparator('li', '|', 1em);

Which will give you this:

li+li:before {
  content: "|";
  padding: 0 1em;
}

This should work in Bash, from a working directory. I've used it in Windows with unixutils installed:

svn info |grep Revision: |cut -c11-

Your syntax is wrong... The correct coding is:

 <?php
mysql_connect("localhost","root","");
mysql_select_db("form1");
$query = mysql_query("SELECT * FROM users WHERE name = 'Admin' ");
while($rows = mysql_fetch_array($query))
{

   $rows = $rows['Name'];
   $address = $rows['Address'];
   $email = $rows['Email'];
   $subject = $rows['Subject'];
   $comment = $rows['Comment']
   echo $rows.'</br>'.$address.'</br>'.$email.'</br>'.$subject.'</br>'.$comment;
}
   ?>

Well yes arrays do exist, and no they're not different to lists when it comes to things like del and append:

>>> from array import array
>>> foo = array('i', range(5))
>>> foo
array('i', [0, 1, 2, 3, 4])
>>> del foo[:]
>>> foo
array('i')
>>> foo.append(42)
>>> foo
array('i', [42])
>>>

Differences worth noting: you need to specify the type when creating the array, and you save storage at the expense of extra time converting between the C type and the Python type when you do arr[i] = expression or arr.append(expression), and lvalue = arr[i]

To import SQL file what works for me

For Wamp-Server

1. Find mysql in wamp. In my computer it's location is "C:\wamp64\bin\mysql\mysql5.7.21\bin"

Open cmd and once you get inside bin you have to write " mysql -uroot -p database_name < filename.sql"

remember to put sql file under bin.

in nutshell you have to do this:-

C:\wamp64\bin\mysql\mysql5.7.21\bin>mysql -uroot -p database_name < filename.sql

After this, it will ask for the password, mine password was nothing(BLANK).

hope it helps someone.

When I had this error, it went away after I my computer crashed and restarted. Try closing and reopening your IDE, if that doesn't work, try restarting your computer. I had just installed the libraries at that point without restarting pycharm when I got this error.

Never closed PyCharm first to test because my blasted computer keeps crashing randomly... working on that one, but it at least solved this problem.. little victories.. :).

Use Datatable.Default.Sort property and then bind it to the datagridview.

In layman terms:- JDK = JRE + Development/debugging tools, where JDK is our complete package to work with Java, from creating compiling till running it.On the other hand JRE is just of running of code(Byte Code).

Note:- Whether we are installing JDK or JRE, JVM would come bundled with both the packages and JVM is the part where JIT compiler converts the byte code into the machine specific code.

Just read the article on JDK,JRE ,JVM and JIT

ChangeDetectorRef approach

import { Component, OnInit, ChangeDetectorRef } from '@angular/core';

export class MyComponent {

    constructor(private cdr: ChangeDetectorRef) { }

    selected(item: any) {
        if (item == 'Department')
            this.isDepartment = true;
        else
            this.isDepartment = false;
        this.cdr.detectChanges();
    }

}

Serialisation in java is not meant as long term persistence or transport format - it is too fragile for this. With the slightest difference in class bytecode and JVM, your data is not readable anymore. Use XML or JSON data-binding for your task (XStream is fast and easy to use, and there are a ton of alternatives)

Add "bDestroy": true in your dataTable Like:-

   $('#example').dataTable({
    ....
    stateSave: true,
    "bDestroy": true
    });

It Will Work.

One useful example that I came across may be helpful:

from itertools import groupby

#user input

myinput = input()

#creating empty list to store output

myoutput = []

for k,g in groupby(myinput):

    myoutput.append((len(list(g)),int(k)))

print(*myoutput)

Sample input: 14445221

Sample output: (1,1) (3,4) (1,5) (2,2) (1,1)

Oracle SQL Developer connection to Microsoft SQL Server

In my case I had to place the ntlmauth.dll in the sql-developer application directory itself (i.e. sql-developer\jdk\jre\bin). Why this location over the system jre/bin I have no idea. But it worked.

PreparedStatements are the way to go in most, but not all cases. Sometimes you will find yourself in a situation where a query, or a part of it, has to be built and stored as a string for later use. Check out the SQL Injection Prevention Cheat Sheet on the OWASP Site for more details and APIs in different programming languages.

One option is to make two plots side by side. ggplot2 provides a nice option for this with facet_wrap():

dat <- data.frame(x = c(rnorm(100), rnorm(100, 10, 2))
  , y = c(rnorm(100), rlnorm(100, 9, 2))
  , index = rep(1:2, each = 100)
  )

require(ggplot2)
ggplot(dat, aes(x,y)) + 
geom_point() + 
facet_wrap(~ index, scales = "free_y")

Here is what you can do if you want to add a column of numbers in Excel. ( I am using Excel 2010 but should not make a difference.)

Example: Lets say you want to add the cells in Column B form B10 to B100 & want the answer to be in cell X or be Variable X ( X can be any cell or any variable you create such as Dim X as integer, etc). Here is the code:

Range("B5") = "=SUM(B10:B100)"

or

X = "=SUM(B10:B100)

There are no quotation marks inside the parentheses in "=Sum(B10:B100) but there are quotation marks inside the parentheses in Range("B5"). Also there is a space between the equals sign and the quotation to the right of it.

It will not matter if some cells are empty, it will simply see them as containing zeros!

This should do it for you!

After having spent over an hour going in rounds swearing at Samsung (mostly), Google, and who not, here are my findings, that finally helped me get the device recognized:

• On Device:
  • Set developer mode
  • Allow USB debugging
  • Default USB configuration > Select USB tethering
  • Connect device to PC USB
• On PC:
  • Elevated cmd/ps prompt (maybe not mandatory, but that was my drill)
  • adb kill-server (precede with .\ in ps)
  • adb start-server (while device connected) > watch for prompt on device
• On device:
  • Always allow connections from this computer > Yes
• On PC:
  • adb devices gets the following output:

You can directly assign a theme when you initiate the Builder:

AlertDialog.Builder builder = new AlertDialog.Builder(
                    getActivity(), R.style.MyAlertDialogTheme);

Then customize your theme in your values/styles.xml

<!-- Alert Dialog -->
<style name="MyAlertDialogTheme" parent="Theme.AppCompat.Dialog.Alert">
    <item name="colorAccent">@color/colorAccent</item>
    <item name="android:colorBackground">@color/alertDialogBackground</item>
    <item name="android:windowBackground">@color/alertDialogBackground</item>

Unutbu gave a really complete answer (they got a +1 from me too), but here is a lo-tech alternative:

>>> x=np.random.randn(5)
>>> x
array([ 0.25276524,  2.28334499, -1.88221637,  0.69949927,  1.0285625 ])
>>> ['{:.2f}'.format(i) for i in x]
['0.25', '2.28', '-1.88', '0.70', '1.03']

As a function (using the format() syntax for formatting):

def ndprint(a, format_string ='{0:.2f}'):
    print [format_string.format(v,i) for i,v in enumerate(a)]

Usage:

>>> ndprint(x)
['0.25', '2.28', '-1.88', '0.70', '1.03']

>>> ndprint(x, '{:10.4e}')
['2.5277e-01', '2.2833e+00', '-1.8822e+00', '6.9950e-01', '1.0286e+00']

>>> ndprint(x, '{:.8g}')
['0.25276524', '2.283345', '-1.8822164', '0.69949927', '1.0285625']

The index of the array is accessible in the format string:

>>> ndprint(x, 'Element[{1:d}]={0:.2f}')
['Element[0]=0.25', 'Element[1]=2.28', 'Element[2]=-1.88', 'Element[3]=0.70', 'Element[4]=1.03']

I could not get IE8+ to work by adding a jQuery event handler to the file input type. I had to go old-school and add the the onchange="" attribute to the input tag:

   var fn = $(elm).val();
   ....
}

EDIT:

function getFileName(elm) {

One way is just to revert your settings: If you delete the Metadata folder in your workspace eclipse will revert to its factory state for all settings (both perspective and general).

When I go to the control panel of my webhost, open up phpMyAdmin, and click on "Show MySQL runtime information", I get:

This MySQL server has been running for 53 days, 15 hours, 28 minutes and 53 seconds. It started up on Oct 24, 2008 at 04:03 AM.

Query statistics: Since its startup, 3,444,378,344 queries have been sent to the server.

That's an average of 743 mySQL queries every single second for the past 53 days!

I don't know about you, but to me that's fast! Very fast!!

I want to add this answer because the DBCC CHECKIDENT-approach will product problems when you use schemas for tables. Use this to be sure:

DECLARE @Table AS NVARCHAR(500) = 'myschema.mytable';
DBCC CHECKIDENT (@Table, RESEED, 0);

If you want to check the success of the operation, use

SELECT IDENT_CURRENT(@Table);

which should output 0 in the example above.

if you want to do very quick plots with secondary Y-Axis then there is much easier way using Pandas wrapper function and just 2 lines of code. Just plot your first column then plot the second but with parameter secondary_y=True, like this:

df.A.plot(label="Points", legend=True)
df.B.plot(secondary_y=True, label="Comments", legend=True)

This would look something like below:

You can do few more things as well. Take a look at Pandas plotting doc.

Converting the date without specifying the current format can bring this error to you easily.

Here is an example:

sdate <- "2015.10.10"

Convert without specifying the Format:

date <- as.Date(sdate4) # ==> This will generate the same error"""Error in charToDate(x): character string is not in a standard unambiguous format""".

Convert with specified Format:

date <- as.Date(sdate4, format = "%Y.%m.%d") # ==> Error Free Date Conversion.

casting of generics is not possible, but if you define the list in another way it is possible to store TestB in it:

List<? extends TestA> myList = new ArrayList<TestA>();

You still have type checking to do when you are using the objects in the list.

You should try this syntax - assuming you want to have @OrderID as a parameter for your stored procedure:

CREATE PROCEDURE dbo.YourStoredProcNameHere
   @OrderID INT
AS
BEGIN
 DECLARE @OrderItemID AS INT
 DECLARE @AppointmentID AS INT
 DECLARE @PurchaseOrderID AS INT
 DECLARE @PurchaseOrderItemID AS INT
 DECLARE @SalesOrderID AS INT
 DECLARE @SalesOrderItemID AS INT

 SELECT @OrderItemID = OrderItemID 
 FROM [OrderItem] 
 WHERE OrderID = @OrderID

 SELECT @AppointmentID = AppoinmentID 
 FROM [Appointment] 
 WHERE OrderID = @OrderID

 SELECT @PurchaseOrderID = PurchaseOrderID 
 FROM [PurchaseOrder] 
 WHERE OrderID = @OrderID

END

OF course, that only works if you're returning exactly one value (not multiple values!)

You guys are making this too hard. PowerShell handles this quite elegantly e.g.:

> $str1 = $null
> if ($str1) { 'not empty' } else { 'empty' }
empty

> $str2 = ''
> if ($str2) { 'not empty' } else { 'empty' }
empty

> $str3 = ' '
> if ($str3) { 'not empty' } else { 'empty' }
not empty

> $str4 = 'asdf'
> if ($str4) { 'not empty' } else { 'empty' }
not empty

> if ($str1 -and $str2) { 'neither empty' } else { 'one or both empty' }
one or both empty

> if ($str3 -and $str4) { 'neither empty' } else { 'one or both empty' }
neither empty

The stackLevel depends on depth you call this method. You can try from 0 to a large number to see what difference.

If stackLevel is legal, you will get string like java.lang.Thread.getStackTrace(Thread.java:1536)

public static String getCodeLocationInfo(int stackLevel) {
        StackTraceElement[] stackTraceElements = Thread.currentThread().getStackTrace();
        if (stackLevel < 0 || stackLevel >= stackTraceElements.length) {
            return "Stack Level Out Of StackTrace Bounds";
        }
        StackTraceElement stackTraceElement = stackTraceElements[stackLevel];
        String fullClassName = stackTraceElement.getClassName();
        String methodName = stackTraceElement.getMethodName();
        String fileName = stackTraceElement.getFileName();
        int lineNumber = stackTraceElement.getLineNumber();

        return String.format("%s.%s(%s:%s)", fullClassName, methodName, fileName, lineNumber);
}

Sorry, I solved my problem with the code above:

$("#captureImage").live("change", function() {
    if($("#captureImage:checked").val() !== undefined) {
        navigator.device.capture.captureImage(function(mediaFiles) {
            console.log("works");
        }, function(exception) {
            $("#captureImage").removeAttr('checked').checkboxradio('refresh');
            _callback.error(exception);
        }, {});
    }
});

Use the return keyword.

return; //exit this event

This worked like magic for me.

celltype_hesc_bool = expr['cell_type'] == 'hesc'

expr_celltype_hesc = expr[celltype_hesc]

In the interpreter its easy to restart it and fix such problems. If you don't want to restart the interpreter, there is another way to fix it:

Python 2.6.6 (r266:84292, Dec 27 2010, 00:02:40)
[GCC 4.4.5] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> l = [1,2,3]
>>> sum(l)
6
>>> sum = 0 # oops! shadowed a builtin!
>>> sum(l)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'int' object is not callable
>>> import sys
>>> sum = sys.modules['__builtin__'].sum # -- fixing sum
>>> sum(l)
6

This also comes in handy if you happened to assign a value to any other builtin, like dict or list

imageView.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT));

  const el = document.getElementById("editable");
  el.focus()
  let char = 1, sel; // character at which to place caret

  if (document.selection) {
    sel = document.selection.createRange();
    sel.moveStart('character', char);
    sel.select();
  }
  else {
    sel = window.getSelection();
    sel.collapse(el.lastChild, char);
  }

For me it worked to delete a Capability and then add it back.

The HTML parser simply doesn't interpret the inlined javascript like this.

You may do this :

<td><input type="checkbox" id="repriseCheckBox" name="repriseCheckBox"/></td>

<script>document.getElementById("repriseCheckBox").disabled=checkStat == 1 ? true : false;</script>

There are a few steps you need to take to properly store this information in your localStorage. Before we get down to the code however, please note that localStorage (at the current time) cannot hold any data type except for strings. You will need to serialize the array for storage and then parse it back out to make modifications to it.

Step 1:

The First code snippet below should only be run if you are not already storing a serialized array in your localStorage session variable.
To ensure your localStorage is setup properly and storing an array, run the following code snippet first:

var a = [];
a.push(JSON.parse(localStorage.getItem('session')));
localStorage.setItem('session', JSON.stringify(a));

The above code should only be run once and only if you are not already storing an array in your localStorage session variable. If you are already doing this skip to step 2.

Step 2:

Modify your function like so:

function SaveDataToLocalStorage(data)
{
    var a = [];
    // Parse the serialized data back into an aray of objects
    a = JSON.parse(localStorage.getItem('session')) || [];
    // Push the new data (whether it be an object or anything else) onto the array
    a.push(data);
    // Alert the array value
    alert(a);  // Should be something like [Object array]
    // Re-serialize the array back into a string and store it in localStorage
    localStorage.setItem('session', JSON.stringify(a));
}

This should take care of the rest for you. When you parse it out, it will become an array of objects.

Hope this helps.

To simply add ActionBar Compat your activity or application should use @style/Theme.AppCompat theme in AndroidManifest.xml like this:

   <activity
        ...
        android:theme="@style/Theme.AppCompat" />

This will add actionbar in activty(or all activities if you added this theme to application)

But usually you need to customize you actionbar. To do this you need to create two styles with Theme.AppCompat parent, for example, "@style/Theme.AppCompat.Light". First one will be for api 11>= (versions of android with build in android actionbar), second one for api 7-10 (no build in actionbar).

Let's look at first style. It will be located in res/values-v11/styles.xml . It will look like this:

<style name="Theme.Styled" parent="@style/Theme.AppCompat.Light">
    <!-- Setting values in the android namespace affects API levels 11+ -->
    <item name="android:actionBarStyle">@style/Widget.Styled.ActionBar</item>
</style>

<style name="Widget.Styled.ActionBar" parent="@style/Widget.AppCompat.Light.ActionBar">
    <!-- Setting values in the android namespace affects API levels 11+ -->
    <item name="android:background">@drawable/ab_custom_solid_styled</item>
    <item name="android:backgroundStacked"
      >@drawable/ab_custom_stacked_solid_styled</item>
    <item name="android:backgroundSplit"
      >@drawable/ab_custom_bottom_solid_styled</item>
</style>

And you need to have same style for api 7-10. It will be located in res/values/styles.xml, BUT because that api levels don't yet know about original android actionbar style items, we should use one, provided by support library. ActionBar Compat items are defined just like original android, but without "android:" part in the front:

<style name="Theme.Styled" parent="@style/Theme.AppCompat.Light">
    <!-- Setting values in the default namespace affects API levels 7-11 -->
    <item name="actionBarStyle">@style/Widget.Styled.ActionBar</item>
</style>

<style name="Widget.Styled.ActionBar" parent="@style/Widget.AppCompat.Light.ActionBar">
    <!-- Setting values in the default namespace affects API levels 7-11 -->
    <item name="background">@drawable/ab_custom_solid_styled</item>
    <item name="backgroundStacked">@drawable/ab_custom_stacked_solid_styled</item>
    <item name="backgroundSplit">@drawable/ab_custom_bottom_solid_styled</item>
</style>

Please mark that, even if api levels higher than 10 already have actionbar you should still use AppCompat styles. If you don't, you will have this error on launch of Acitvity on devices with android 3.0 and higher:

java.lang.IllegalStateException: You need to use a Theme.AppCompat theme (or descendant) with this activity.

P.S. Sorry for my English

I use resolve to save the current state data before moving to the new state:

angular.module('MyModule')
.config(['$stateProvider', function ($stateProvider) {
    $stateProvider
        .state('mystate', {
            templateUrl: 'mytemplate.html',
            controller: ["PreviousState", function (PreviousState) {
                if (PreviousState.Name == "mystate") {
                    // ...
                }
            }],
            resolve: {
                PreviousState: ["$state", function ($state) {
                    var currentStateData = {
                        Name: $state.current.name,
                        Params: $state.params,
                        URL: $state.href($state.current.name, $state.params)
                    };
                    return currentStateData;
                }]
            }
        });
}]);

1.in your main controllview :

 if let filePath = Bundle.main.path(forResource: "clip", ofType: "mp4") {
            let fileURL = NSURL(fileURLWithPath: filePath)
            videoPlayer = VideoPlayer(urlAsset: fileURL, view: playerView)
            if let player = videoPlayer {
                player.playerRate = 1.00

     import AVFoundation
   
     import UIKit
   
     class PlayerView: UIView {
   
   
   override class var layerClass: AnyClass {
       get {
         return AVPlayerLayer.self
       }
   }
   
   
   var player:AVPlayer? {
       set {
           if let layer = layer as? AVPlayerLayer {
               layer.player = player
           }
       }
       get {
           if let layer = layer as? AVPlayerLayer {
               return layer.player
           } else {
               return nil
           }
       }
   }
   }
   

You can do something like this to check if any mysql process is running or not:

ps aux | grep mysqld
ps aux | grep mysql

Then if it is running you can killall by using(depending on what all processes are running currently):

killall -9 mysql
killall -9 mysqld
killall -9 mysqld_safe    

var index;
yourArray.some(function (elem, i) {
    return elem.prop2 === 'yutu' ? (index = i, true) : false;
});

Iterate over all elements of array. It returns either the index and true or false if the condition does not match.

Important is the explicit return value of true (or a value which boolean result is true). The single assignment is not sufficient, because of a possible index with 0 (Boolean(0) === false), which would not result an error but disables the break of the iteration.

Edit

An even shorter version of the above:

yourArray.some(function (elem, i) {
    return elem.prop2 === 'yutu' && ~(index = i);
});

list all your docker images:

docker images

list all existed docker containers:

docker ps -a

delete all the targeted containers, which is using the image that you want to delete:

docker rm <container-id>

delete the targeted image:

docker rmi <image-name:image-tag or image-id>

a = np.array([1,2,3])
b = np.array([4,5,6])
np.array((a,b))

works just as well as

np.array([[1,2,3], [4,5,6]])

Regardless of whether it is a list of lists or a list of 1d arrays, np.array tries to create a 2d array.

But it's also a good idea to understand how np.concatenate and its family of stack functions work. In this context concatenate needs a list of 2d arrays (or any anything that np.array will turn into a 2d array) as inputs.

np.vstack first loops though the inputs making sure they are at least 2d, then does concatenate. Functionally it's the same as expanding the dimensions of the arrays yourself.

np.stack is a new function that joins the arrays on a new dimension. Default behaves just like np.array.

Look at the code for these functions. If written in Python you can learn quite a bit. For vstack:

return _nx.concatenate([atleast_2d(_m) for _m in tup], 0)

You DO NOT have to provide a body for getters and setters IF you'd like the automated compiler to provide a basic implementation.

This DOES however require you to make sure you're using the v3.5 compiler by updating your web.config to something like

 <compilers>
   <compiler language="c#;cs;csharp" extension=".cs" type="Microsoft.CSharp.CSharpCodeProvider,System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" warningLevel="4">
    <providerOption name="CompilerVersion" value="v3.5"/>
    <providerOption name="WarnAsError" value="false"/>
  </compiler>
</compilers>

You'll need to use a static readonly list instead. And if you want the list to be immutable then you might want to consider using ReadOnlyCollection<T> rather than List<T>.

private static readonly ReadOnlyCollection<string> _metrics =
    new ReadOnlyCollection<string>(new[]
        {
            SourceFile.LOC,
            SourceFile.MCCABE,
            SourceFile.NOM,
            SourceFile.NOA,
            SourceFile.FANOUT,
            SourceFile.FANIN,
            SourceFile.NOPAR,
            SourceFile.NDC,
            SourceFile.CALLS
        });

public static ReadOnlyCollection<string> Metrics
{
    get { return _metrics; }
}

I had the same error message while trying to deploy the application. In Spring, the security configuration xml can be a different one from applicationContext.xml, usually applicationContext-security.xml inside WEB-INF folder. The changes to be applied are for web.xml

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>
        /WEB-INF/applicationContext.xml
        /WEB-INF/applicationContext-security.xml
    </param-value>
</context-param>

And the applicationContext.xml would look like:

<?xml version="1.0" encoding="UTF-8"?>
<beans:beans xmlns="http://www.springframework.org/schema/security"
    xmlns:beans="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
                        http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security-3.1.xsd">

    <http auto-config='true'>

        <intercept-url pattern="/**" access="ROLE_USER" />
        <form-login login-page='login.jsp'/>
    </http>

</beans:beans>

Even after you make these changes, the namespace error will exist. To get rid of this, add the following jar files to the WEB-INF/lib and then to the library:

• spring-security-acl-3.1.0.M2.jar
• spring-security-config-3.1.0.M2.jar
• spring-security-core-3.1.0.M2.jar
• spring-security-taglibs-3.1.0.M2.jar
• spring-security-web-3.1.0.M2.jar

As you can see in the code of angular-JS ( https://github.com/angular/angular.js/blob/master/src/ng/filter/orderBy.js ) ng-repeat does not work with objects. Here is a hack with sortFunction.

http://jsfiddle.net/sunnycpp/qaK56/33/

<div ng-app='myApp'>
    <div ng-controller="controller">
    <ul>
        <li ng-repeat="test in testData | orderBy:sortMe()">
            Order = {{test.value.order}} -> Key={{test.key}} Name=:{{test.value.name}}
        </li>
    </ul>
    </div>
</div>

myApp.controller('controller', ['$scope', function ($scope) {

    var testData = {
        a:{name:"CData", order: 2},
        b:{name:"AData", order: 3},
        c:{name:"BData", order: 1}
    };
    $scope.testData = _.map(testData, function(vValue, vKey) {
        return { key:vKey, value:vValue };
    }) ;
    $scope.sortMe = function() {
        return function(object) {
            return object.value.order;
        }
    }
}]);

try this one last:

so I tried all the suggestions on this page.. none worked.. The way my problem started was by following the steps in this tutorial that teaches how to link static libraries. With my sample project the instructions worked fine.. but then on my actual project I started getting the error above.

So what I did was go through each step of the said tutorial and built after each step.. the offending line turned out to be this one: adding -all_load to build settings-> other linker flags

it turns out that this flag was recommended once upon a time to link categories to static libraries.. but then it turned out that this flag was no longer necessary Xcode 4.2+.. (same goes for the -force_load flag.. which was also recommended in other posts)..

Another solution is to use WMI.NET or Windows Management Instrumentation.

Using the .NET Framework namespace System.Management, you can automate administrative tasks using Windows Management Instrumentation (WMI).

Code Sample

using System.Management;
...
var processToRun = new[] { "notepad.exe" };
var connection = new ConnectionOptions();
connection.Username = "username";
connection.Password = "password";
var wmiScope = new ManagementScope(String.Format("\\\\{0}\\root\\cimv2", REMOTE_COMPUTER_NAME), connection);
var wmiProcess = new ManagementClass(wmiScope, new ManagementPath("Win32_Process"), new ObjectGetOptions());
wmiProcess.InvokeMethod("Create", processToRun);

If you have trouble with authentication, then check the DCOM configuration.

1. On the target machine, run dcomcnfg from the command prompt.
2. Expand Component Services\Computers\My Computer\DCOM Config
3. Find Windows Management Instruction, identified with GUID 8BC3F05E-D86B-11D0-A075-00C04FB68820 (you can see this in the details view).
4. Edit the properties and then add the username you are trying to login with under the permissions tab.
5. You may need to reboot the service or the entire machine.

NOTE: All paths used for the remote process need to be local to the target machine.

<TextBlock Text="Stuff on line1&#x0a;Stuff on line 2"/>

You can use any hexadecimally encoded value to represent a literal. In this case, I used the line feed (char 10). If you want to do "classic" vbCrLf, then you can use 


By the way, note the syntax: It's the ampersand, a pound, the letter x, then the hex value of the character you want, and then finally a semi-colon.

ALSO: For completeness, you can bind to a text that already has the line feeds embedded in it like a constant in your code behind, or a variable constructed at runtime.

Drop the spaces around the = sign:

#!/bin/bash 
STR="Hello World" 
echo $STR 

If you need to add emails as CC or BCC, add the following part in the variable you use as for your header :

$headers .= "CC: [email protected]".PHP_EOL;
$headers .= "BCC: [email protected]".PHP_EOL;

What I am wondering is if there is any strange way to make this check even faster, maybe exploiting some strange method in Regexp or some weird construct.

Regexp engines vary in how they implement searches, but, in general, anchor your patterns for speed, and avoid greedy matches, especially when searching long strings.

The best thing to do, until you're familiar with how a particular engine works, is to do benchmarks and add/remove anchors, try limiting searches, use wildcards vs. explicit matches, etc.

The Fruity gem is very useful for quickly benchmarking things, because it's smart. Ruby's built-in Benchmark code is also useful, though you can write tests that fool you by not being careful.

I've used both in many answers here on Stack Overflow, so you can search through my answers and will see lots of little tricks and results to give you ideas of how to write faster code.

The biggest thing to remember is, it's bad to prematurely optimize your code before you know where the slowdowns occur.

If you have your dates in DateTime variables, they don't have a format.

You can use the Date property to return a DateTime value with the time portion set to midnight. So, if you have:

DateTime dt1 = DateTime.Parse("07/12/2011");
DateTime dt2 = DateTime.Now;

if(dt1.Date > dt2.Date)
{
     //It's a later date
}
else
{
     //It's an earlier or equal date
}

From Java documentation

If a class has no modifier (the default, also known as package-private), it is visible only within its own package (packages are named groups of related classes — you will learn about them in a later lesson.)

At the member level, you can also use the public modifier or no modifier (package-private) just as with top-level classes, and with the same meaning.

Full story you can read here (_{Which I wrote recently}):

http://codeinventions.blogspot.com/2014/09/default-access-modifier-in-java-or-no.html

append(): It is basically used in Python to add one element.

Example 1:

>> a = [1, 2, 3, 4]
>> a.append(5)
>> print(a)
>> a = [1, 2, 3, 4, 5]

Example 2:

>> a = [1, 2, 3, 4]
>> a.append([5, 6])
>> print(a)
>> a = [1, 2, 3, 4, [5, 6]]

extend(): Where extend(), is used to merge two lists or insert multiple elements in one list.

Example 1:

>> a = [1, 2, 3, 4]
>> b = [5, 6, 7, 8]
>> a.extend(b)
>> print(a)
>> a = [1, 2, 3, 4, 5, 6, 7, 8]

Example 2:

>> a = [1, 2, 3, 4]
>> a.extend([5, 6])
>> print(a)
>> a = [1, 2, 3, 4, 5, 6]

Disclosure: I wrote the code that Trello uses; the code below is the actual source code Trello uses to accomplish the clipboard trick.

We don't actually "access the user's clipboard", instead we help the user out a bit by selecting something useful when they press Ctrl+C.

Sounds like you've figured it out; we take advantage of the fact that when you want to hit Ctrl+C, you have to hit the Ctrl key first. When the Ctrl key is pressed, we pop in a textarea that contains the text we want to end up on the clipboard, and select all the text in it, so the selection is all set when the C key is hit. (Then we hide the textarea when the Ctrl key comes up.)

Specifically, Trello does this:

TrelloClipboard = new class
  constructor: ->
    @value = ""

    $(document).keydown (e) =>
      # Only do this if there's something to be put on the clipboard, and it
      # looks like they're starting a copy shortcut
      if !@value || !(e.ctrlKey || e.metaKey)
        return

      if $(e.target).is("input:visible,textarea:visible")
        return

      # Abort if it looks like they've selected some text (maybe they're trying
      # to copy out a bit of the description or something)
      if window.getSelection?()?.toString()
        return

      if document.selection?.createRange().text
        return

      _.defer =>
        $clipboardContainer = $("#clipboard-container")
        $clipboardContainer.empty().show()
        $("<textarea id='clipboard'></textarea>")
        .val(@value)
        .appendTo($clipboardContainer)
        .focus()
        .select()

    $(document).keyup (e) ->
      if $(e.target).is("#clipboard")
        $("#clipboard-container").empty().hide()

  set: (@value) ->

In the DOM we've got:

<div id="clipboard-container"><textarea id="clipboard"></textarea></div>

CSS for the clipboard stuff:

#clipboard-container {
  position: fixed;
  left: 0px;
  top: 0px;
  width: 0px;
  height: 0px;
  z-index: 100;
  display: none;
  opacity: 0;
}
#clipboard {
  width: 1px;
  height: 1px;
  padding: 0px;
}

... and the CSS makes it so you can't actually see the textarea when it pops in ... but it's "visible" enough to copy from.

When you hover over a card, it calls

TrelloClipboard.set(cardUrl)

... so then the clipboard helper knows what to select when the Ctrl key is pressed.

In some developer-friendly ROMs you could just enable Root Access in Settings > Developer option > Root access. After that adb root becomes available. Unfortunately it does not work for most stock ROMs on the market.

Activity:

int number = 5;
Intent i = new Intent(this, MyService.class);
i.putExtra("MyNumber", number);
startService(i);

Service:

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    if (intent != null && intent.getExtras() != null){
        int number = intent.getIntExtra("MyNumber", 0);
    }
}

The solution

svn status | grep ^? | sed 's/?    //' | xargs svn add

does not work with whitespaces. Instead one can use

svn status | grep ^? | sed 's/^?       //' | xargs -I fn svn add "fn"

(seems like the number of leading blanks is different on my system -- just adjust it).

thing_index = thing_list.index(elem) if elem in thing_list else -1

One line. Simple. No exceptions.

All files must be delete from the directory before it is deleted.

There are third party libraries that have a lot of common utilities, including ones that does that for you:

• Apache commons-lang FileUtils.forceDelete(..)
• guava Files.deleteRecursively(..)

UPDATE

You can use document.location.reload(true) as mentioned below instead of the forced trick below.

Replace your HTML with this:

<!DOCTYPE html>
<html>
    <head>
        <style type="text/css">
            body { 
                background-image: url('../Images/Black-BackGround.gif');
                background-repeat: repeat;
            }
            body td {
               font-Family: Arial; 
               font-size: 12px; 
            }
            #Nav a { 
                position:relative; 
                display:block; 
                text-decoration: none; 
                color:black; 
            }
        </style>
        <script type="text/javascript">
            function refreshPage () {
                var page_y = document.getElementsByTagName("body")[0].scrollTop;
                window.location.href = window.location.href.split('?')[0] + '?page_y=' + page_y;
            }
            window.onload = function () {
                setTimeout(refreshPage, 35000);
                if ( window.location.href.indexOf('page_y') != -1 ) {
                    var match = window.location.href.split('?')[1].split("&")[0].split("=");
                    document.getElementsByTagName("body")[0].scrollTop = match[1];
                }
            }
        </script>
    </head>
    <body><!-- BODY CONTENT HERE --></body>
</html>

You can put link like this (it will be hidden. May be before </body>)

<a id="clickbanner" href="image.jpg" rel="gallery"></a>

And working rel attribute or class like this

$(document).ready(function() {
    $("a[rel=gallery]").fancybox({
        openEffect  : 'elastic',
        closeEffect : 'elastic',
        maxWidth    : 800,
        maxHeight   : 600
    });
});

Just do it with jquery trigger function

$( window ).load(function() {
  $("#clickbanner").trigger('click');
});

Basically error saying your are missing "Android SDK Build-tools" installed.

If you want to display the JSON data in well defined formate you can modify the code as:

file_put_contents($file, json_encode($json,TRUE));


$headers = array('http'=>array('method'=>'GET','header'=>'Content: type=application/json \r\n'.'$agent \r\n'.'$hash'));

$context=stream_context_create($headers);

$str = file_get_contents("list.txt",FILE_USE_INCLUDE_PATH,$context);

$str1=utf8_encode($str);

$str1=json_decode($str1,true);



foreach($str1 as $key=>$value)
{

    echo "key is: $key.\n";

    echo "values are: \t";
        foreach ($value as $k) {

        echo " $k. \t";
        # code...
    }
        echo "<br></br>";
        echo "\n";

}

To the best of my memory, a physical address is an explicit, set in stone address in memory, while a logical address consists of a base pointer and offset.

The reason is as you have basically specified. It allows for not only the segmentation of programs and processes into threads and data, but also for the dynamic loading of such programs, and the allowance for at least pseudo-parallelism, without any actual interlacing of instructions in memory needing to take place.

To delete data from the tables having relationship of parent_child, First you have to delete the data from the child table by mentioning join then simply delete the data from the parent table, example is given below:

DELETE ChildTable
FROM ChildTable inner join ChildTable on PParentTable.ID=ChildTable.ParentTableID
WHERE <WHERE CONDITION> 


DELETE  ParentTable
WHERE <WHERE CONDITION>

Now that the question is clearer, you can just do this in one grep

grep -R --include "*bills*" "put" .

With relevant flags

   -R, -r, --recursive
          Read  all  files  under  each  directory,  recursively;  this is
          equivalent to the -d recurse option.
   --include=GLOB
          Search only files whose base name matches GLOB  (using  wildcard
          matching as described under --exclude).

I have created this Plunker based on your example that updates the object equal to newItem.id

Here's the snippet of my functions:

showUpdatedItem(newItem){
    let updateItem = this.itemArray.items.find(this.findIndexToUpdate, newItem.id);

    let index = this.itemArray.items.indexOf(updateItem);


    this.itemArray.items[index] = newItem;

  }

  findIndexToUpdate(newItem) { 
        return newItem.id === this;
  }

Hope this helps.

"Allocation Failure" is cause of GC to kick is not correct. It is an outcome of GC operation.

GC kicks in when there is no space to allocate( depending on region minor or major GC is performed). Once GC is performed if space is freed good enough, but if there is not enough size it fails. Allocation Failure is one such failure. Below document have good explanation https://docs.oracle.com/javase/8/docs/technotes/guides/vm/gctuning/g1_gc.html

The problem is your query returned false meaning there was an error in your query. After your query you could do the following:

if (!$result) {
    die(mysqli_error($link));
}

Or you could combine it with your query:

$results = mysqli_query($link, $query) or die(mysqli_error($link));

That will print out your error.

Also... you need to sanitize your input. You can't just take user input and put that into a query. Try this:

$query = "SELECT * FROM shopsy_db WHERE name LIKE '%" . mysqli_real_escape_string($link, $searchTerm) . "%'";

In reply to: Table 'sookehhh_shopsy_db.sookehhh_shopsy_db' doesn't exist

Are you sure the table name is sookehhh_shopsy_db? maybe it's really like users or something.

I can suggest you another approach IMHO more robust. Basically you need to broadcast a logout message to all your Activities needing to stay under a logged-in status. So you can use the sendBroadcast and install a BroadcastReceiver in all your Actvities. Something like this:

/** on your logout method:**/
Intent broadcastIntent = new Intent();
broadcastIntent.setAction("com.package.ACTION_LOGOUT");
sendBroadcast(broadcastIntent);

The receiver (secured Activity):

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    /**snip **/
    IntentFilter intentFilter = new IntentFilter();
    intentFilter.addAction("com.package.ACTION_LOGOUT");
    registerReceiver(new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            Log.d("onReceive","Logout in progress");
            //At this point you should start the login activity and finish this one
            finish();
        }
    }, intentFilter);
    //** snip **//
}

If you want to get all unique values without any approximation or setting a magic number (size: 500), then use COMPOSITE AGGREGATION (ES 6.5+).

From official documentation:

"If you want to retrieve all terms or all combinations of terms in a nested terms aggregation you should use the COMPOSITE AGGREGATION which allows to paginate over all possible terms rather than setting a size greater than the cardinality of the field in the terms aggregation. The terms aggregation is meant to return the top terms and does not allow pagination."

Implementation example in JavaScript:

const ITEMS_PER_PAGE = 1000;_x000D_
_x000D_
const body =  {_x000D_
    "size": 0, // Returning only aggregation results: https://www.elastic.co/guide/en/elasticsearch/reference/current/returning-only-agg-results.html_x000D_
    "aggs" : {_x000D_
        "langs": {_x000D_
            "composite" : {_x000D_
                "size": ITEMS_PER_PAGE,_x000D_
                "sources" : [_x000D_
                    { "language": { "terms" : { "field": "language" } } }_x000D_

I would start by reading up on streams on MSDN: http://msdn.microsoft.com/en-us/library/system.io.stream.aspx

Memorystream and FileStream are streams used to work with raw memory and Files respectively...

I agree with Cade Roux.

This article should get you on the right track:

• Indexes in SQL Server 2005/2008 – Best Practices, Part 1
• Indexes in SQL Server 2005/2008 – Part 2 – Internals

One thing to note, clustered indexes should have a unique key (an identity column I would recommend) as the first column. Basically it helps your data insert at the end of the index and not cause lots of disk IO and Page splits.

Secondly, if you are creating other indexes on your data and they are constructed cleverly they will be reused.

e.g. imagine you search a table on three columns

state, county, zip.

• you sometimes search by state only.
• you sometimes search by state and county.
• you frequently search by state, county, zip.

Then an index with state, county, zip. will be used in all three of these searches.

If you search by zip alone quite a lot then the above index will not be used (by SQL Server anyway) as zip is the third part of that index and the query optimiser will not see that index as helpful.

You could then create an index on Zip alone that would be used in this instance.

By the way We can take advantage of the fact that with Multi-Column indexing the first index column is always usable for searching and when you search only by 'state' it is efficient but yet not as efficient as Single-Column index on 'state'

I guess the answer you are looking for is that it depends on your where clauses of your frequently used queries and also your group by's.

The article will help a lot. :-)

in my case, the file command tells a wrong encoding, so i tried converting with all the possible encodings, and found out the right one.

execute this script and check the result file.

for i in `iconv -l`
do
   echo $i
   iconv -f $i -t UTF-8 yourfile | grep "hint to tell converted success or not"
done &>/tmp/converted

This worked for me:

1. Create a new project
2. Create a class in it
3. Add erroneous code, let error come
4. Now go to your project
5. Go to Problems window
6. Double click on a error

It starts showing compilation errors in the code.

awk '{for(i=3;i<=NF;++i)print $i}' 

The inherit value:

a { color: inherit; } 

… will cause the element to take on the colour of its parent (which is what I think you are looking for).

A live demo follows:

a {
  color: inherit;
}

<p>The default color of the html element is black. The default colour of the body and of a paragraph is inherited. This
  <a href="http://example.com">link</a> would normally take on the default link or visited color, but has been styled to inherit the color from the paragraph.</p>

WAMP server generally provide addond for different php/mysql versions. However you mentioned you have downloaded latest wamp server. As of now, latest Wamp server v2.5 provide PHP version 5.5.12

So you need to upgrade it manually as follow:

1. Download binaries on php.net
2. Extract all files in a new folder : C:/wamp/bin/php/php5.5.27/
3. Copy the wampserver.conf from another php folder (like php/php5.5.12/) to the new folder
4. Rename php.ini-development file to phpForApache.ini
5. Done ! Restart WampServer (>Right Mouseclick on trayicon >Exit)

Although not asked, I'd recommend to vagrant/puppet or docker for local development. Check puphpet.com for details. It has slight learning curve but it will give you much better control of different versions of every tool.

You could use a ternary operator like this one, to make it a one liner.

echo ($profitloss < 0) ? 'false' : 'true';

Here is a small JS_Fiddle.

then is a method callback stack which is available after a promise is resolved it is part of library like jQuery but now it is available in native JavaScript and below is the detail explanation how it works

You can do a Promise in native JavaScript : just like there are promises in jQuery, Every promise can be stacked and then can be called with Resolve and Reject callbacks, This is how you can chain asynchronous calls.

I forked and Edited from MSDN Docs on Battery charging status..

What this does is try to find out if user laptop or device is charging battery. then is called and you can do your work post success.

navigator
    .getBattery()
    .then(function(battery) {
       var charging = battery.charging;
       alert(charging);
    })
    .then(function(){alert("YeoMan : SINGH is King !!");});

Another es6 Example

function fetchAsync (url, timeout, onData, onError) {
    …
}
let fetchPromised = (url, timeout) => {
    return new Promise((resolve, reject) => {
        fetchAsync(url, timeout, resolve, reject)
    })
}
Promise.all([
    fetchPromised("http://backend/foo.txt", 500),
    fetchPromised("http://backend/bar.txt", 500),
    fetchPromised("http://backend/baz.txt", 500)
]).then((data) => {
    let [ foo, bar, baz ] = data
    console.log(`success: foo=${foo} bar=${bar} baz=${baz}`)
}, (err) => {
    console.log(`error: ${err}`)
})

Definition :: then is a method used to solve Asynchronous callbacks

this is introduced in ES6

Please find the proper documentation here Es6 Promises

$fromMail = 'set your from mail';
$boundary = str_replace(" ", "", date('l jS \of F Y h i s A'));

$contentHtml = '<div>Dear Admin<br /><br />The following design is submitted by '. $userName .'.<br /><br /><a href="'.$sdLink.'"><b>Click here</b></a> to check the design.</div>';
$contentHtml .= '<div><a href="'.$imageUrl.'"><img src="'.$imageUrl.'" width="250" height="95" border="0" alt="my picture"></a></div>';
$contentHtml .= '<div>Name : '.$name.'<br />Description : '. $description .'</div>';

$headersMail = '';
$headersMail .= 'From: ' . $fromMail . "\r\n" . 'Reply-To: ' . $fromMail . "\r\n";
$headersMail .= 'Return-Path: ' . $fromMail . "\r\n";

$headersMail .= 'Content-Transfer-Encoding: base64' . "\r\n\r\n";
$headersMail .= rtrim(chunk_split(base64_encode($contentHtml)));

try {
    if (mail($toMail, $subjectMail, "", $headersMail)) {
        $status = 'success';
        $msg = 'Mail sent successfully.';
    } else {
        $status = 'failed';
        $msg = 'Unable to send mail.';
    }
} catch(Exception $e) {
    $msg = $e->getMessage();
}

This works fine for me.It includes mail with image and a link and works for all sorts of mail ids. The clue is to use all the header perfectly.

If you are testing it from localhost, then set the below before checking:

How to set mail send from localhost xampp:

1. comment everything in D:/xampp/sendmail/sendmail.ini and mention the below under

   [sendmail]

   smtp_server=smtp.gmail.com smtp_port=587 error_logfile=error.log debug_logfile=debug.log [email protected] auth_password=your-mail-password [email protected]

2. In D:/xampp/php/php.ini a. Under

   [mail function]

   SMTP = smtp.gmail.com smtp_port = 587

b. set sendmail_from = [email protected] c. uncomment sendmail_path = "\"D:\xamp\sendmail\sendmail.exe\" -t" Hence it should be look like below

sendmail_path = "\"D:\xamp\sendmail\sendmail.exe\" -t"

d. comment sendmail_path="D:\xamp\mailtodisk\mailtodisk.exe" Hence it should be look like below

;sendmail_path="D:\xamp\mailtodisk\mailtodisk.exe"

e. mail.add_x_header=Off

I recommend you to read more about the this keyword.

You cannot expect "this" to select the "select" tag in this case.

What you want to do in this case is use obj.id to get the id of select tag.

Add this code to sort the data in text file. Collections.sort(list);

In my xml file, the header looked like this:

<?xml version="1.0" encoding="utf-16"? />

In a test file, I was reading the file bytes and decoding the data as UTF-8 (not realizing the header in this file was utf-16) to create a string.

byte[] data = Files.readAllBytes(Paths.get(path));
String dataString = new String(data, "UTF-8");

When I tried to deserialize this string into an object, I was seeing the same error:

javax.xml.stream.XMLStreamException: ParseError at [row,col]:[1,1]
Message: Content is not allowed in prolog.

When I updated the second line to

String dataString = new String(data, "UTF-16");

I was able to deserialize the object just fine. So as Romain had noted above, the encodings need to match.

I implemented a pinch zoom for my TextView, using this tutorial. The resulting code is this:

private GestureDetector gestureDetector;
private View.OnTouchListener gestureListener;

and in onCreate():

    // Zoom handlers
    gestureDetector = new GestureDetector(new MyGestureDetector());
    gestureListener = new View.OnTouchListener() {

        // We can be in one of these 2 states
        static final int NONE = 0;
        static final int ZOOM = 1;
        int mode = NONE;

        static final int MIN_FONT_SIZE = 10;
        static final int MAX_FONT_SIZE = 50;

        float oldDist = 1f;

        @Override
        public boolean onTouch(View v, MotionEvent event) {
            TextView textView = (TextView) findViewById(R.id.text);

            switch (event.getAction() & MotionEvent.ACTION_MASK) {
                case MotionEvent.ACTION_POINTER_DOWN:
                    oldDist = spacing(event);
                    Log.d(TAG, "oldDist=" + oldDist);
                    if (oldDist > 10f) {
                       mode = ZOOM;
                       Log.d(TAG, "mode=ZOOM" );
                    }
                    break;
                case MotionEvent.ACTION_POINTER_UP:
                    mode = NONE;
                    break;
                case MotionEvent.ACTION_MOVE:
                    if (mode == ZOOM) {
                        float newDist = spacing(event);
                        // If you want to tweak font scaling, this is the place to go.
                        if (newDist > 10f) {
                            float scale = newDist / oldDist;

                            if (scale > 1) {
                                scale = 1.1f;
                            } else if (scale < 1) {
                                scale = 0.95f;
                            }

                            float currentSize = textView.getTextSize() * scale;
                            if ((currentSize < MAX_FONT_SIZE && currentSize > MIN_FONT_SIZE)
                                    ||(currentSize >= MAX_FONT_SIZE && scale < 1)
                                    || (currentSize <= MIN_FONT_SIZE && scale > 1)) {
                                textView.setTextSize(TypedValue.COMPLEX_UNIT_PX, currentSize);
                            }
                        }
                    }
                    break;
                }
            return false;
        }

Magic constants 1.1 and 0.95 were chosen empirically (using scale variable for this purpose made my TextView behave kind of weird).

RemoteSigned: all scripts you created yourself will be run, and all scripts downloaded from the Internet will need to be signed by a trusted publisher.

OK, change the policy by simply typing:

Set-ExecutionPolicy RemoteSigned

The low level iterator manipulate code:

List<Money> myMoney = new List<Money>
{
    new Money{amount = 10, type = "US"},
    new Money{amount = 20, type = "US"}
};
using (var enumerator = myMoney.GetEnumerator())
{
    while (enumerator.MoveNext())
    {
        var element = enumerator.Current;
        Console.WriteLine(element.amount);
    }
}

Another way to insert <br> between text lines that are defined in an array:

import react, { Fragment } from 'react';

const lines = [
  'One line',
  'Another line',
];

const textContent =
  lines.reduce(items, line, index) => {
    if (index > 0) {
      items.push(<br key={'br-'+index}/>);
    }
    items.push(<Fragment key={'item-'+index}>{line}</Fragment>);
    return items;
  }, []);

Then the text can be used as variable:

<Text>{textContent}</Text>

If not available, Fragment can be defined this way:

const Fragment = (props) => props.children;

Using Bootstrap 4.4.1, I was able to set the number of cards per deck using simple classes by adding some scss into the mix.

It's probably easiest to create your query object directly as:

  Test.find({
      $and: [
          { $or: [{a: 1}, {b: 1}] },
          { $or: [{c: 1}, {d: 1}] }
      ]
  }, function (err, results) {
      ...
  }

But you can also use the Query#and helper that's available in recent 3.x Mongoose releases:

  Test.find()
      .and([
          { $or: [{a: 1}, {b: 1}] },
          { $or: [{c: 1}, {d: 1}] }
      ])
      .exec(function (err, results) {
          ...
      });

Or if it's from a database context you can use

@Html.DropDownListFor(model => model.MyOption, db.MyOptions.Select(x => new SelectListItem { Text = x.Name, Value = x.Id.ToString() }))

Async Arrow function syntax with parameters

const myFunction = async (a, b, c) => {
   // Code here
}

You should do something like this:

1) create directory object what would point to server-side accessible folder

CREATE DIRECTORY image_files AS '/data/images'
/

2) Place your file into OS folder directory object points to

3) Give required access privileges to Oracle schema what will load data from file into table:

GRANT READ ON DIRECTORY image_files TO scott
/

4) Use BFILENAME, EMPTY_BLOB functions and DBMS_LOB package (example NOT tested - be care) like in below:

DECLARE
  l_blob BLOB; 
  v_src_loc  BFILE := BFILENAME('IMAGE_FILES', 'myimage.png');
  v_amount   INTEGER;
BEGIN
  INSERT INTO esignatures  
  VALUES (100, 'BOB', empty_blob()) RETURN iblob INTO l_blob; 
  DBMS_LOB.OPEN(v_src_loc, DBMS_LOB.LOB_READONLY);
  v_amount := DBMS_LOB.GETLENGTH(v_src_loc);
  DBMS_LOB.LOADFROMFILE(l_blob, v_src_loc, v_amount);
  DBMS_LOB.CLOSE(v_src_loc);
  COMMIT;
END;
/

After this you get the content of your file in BLOB column and can get it back using Java for example.

edit: One letter left missing: it should be LOADFROMFILE.

This may sound dumb, but it may be a fresh, or damaged install, so is the JDK installed? If not, go to the download site and download the latest version of Java JRE. Like I said, this may sound dumb, but it solved my problem.

According to Tom Hawtin

A closure is a block of code that can be referenced (and passed around) with access to the variables of the enclosing scope.

Now I'm trying to emulate the JavaScript closure example on Wikipedia, with a "straigth" translation to Java, in the hope to be useful:

//ECMAScript
var f, g;
function foo() {
  var x = 0;
  f = function() { return ++x; };
  g = function() { return --x; };
  x = 1;
  print('inside foo, call to f(): ' + f()); // "2"  
}
foo();
print('call to g(): ' + g()); // "1"
print('call to f(): ' + f()); // "2"

Now the java part: Function1 is "Functor" interface with arity 1 (one argument). Closure is the class implementing the Function1, a concrete Functor that acts as function (int -> int). In the main() method I just instantiate foo as a Closure object, replicating the calls from the JavaScript example. The IntBox class is just a simple container, it behave like an array of 1 int:

int a[1] = {0}

interface Function1   {
    public final IntBag value = new IntBag();
    public int apply();
}

class Closure implements Function1 {
   private IntBag x = value;
   Function1 f;
   Function1 g;

   @Override
   public int apply()  {
    // print('inside foo, call to f(): ' + f()); // "2"
    // inside apply, call to f.apply()
       System.out.println("inside foo, call to f.apply(): " + f.apply());
       return 0;
   }

   public Closure() {
       f = new Function1() {
           @Override
           public int apply()  {
               x.add(1);
                return x.get();
           }
       };
       g = new Function1() {
           @Override
           public int apply()  {
               x.add(-1);
               return x.get();
           }
       };
    // x = 1;
       x.set(1);
   }
}
public class ClosureTest {
    public static void main(String[] args) {
        // foo()
        Closure foo = new Closure();
        foo.apply();
        // print('call to g(): ' + g()); // "1"
        System.out.println("call to foo.g.apply(): " + foo.g.apply());
        // print('call to f(): ' + f()); // "2"
        System.out.println("call to foo.f.apply(): " + foo.f.apply());

    }
}

It prints:

inside foo, call to f.apply(): 2
call to foo.g.apply(): 1
call to foo.f.apply(): 2

Dispose pattern:

public abstract class DisposableObject : IDisposable
{
    public bool Disposed { get; private set;}      

    public void Dispose()
    {
        Dispose(true);
        GC.SuppressFinalize(this);
    }

    ~DisposableObject()
    {
        Dispose(false);
    }

    private void Dispose(bool disposing)
    {
        if (!Disposed)
        {
            if (disposing)
            {
                DisposeManagedResources();
            }

            DisposeUnmanagedResources();
            Disposed = true;
        }
    }

    protected virtual void DisposeManagedResources() { }
    protected virtual void DisposeUnmanagedResources() { }
}

Example of inheritance:

public class A : DisposableObject
{
    public Component components_a { get; set; }
    private IntPtr handle_a;

    protected override void DisposeManagedResources()
    {
        try
        {
          Console.WriteLine("A_DisposeManagedResources");
          components_a.Dispose();
          components_a = null;
        }
        finally
        { 
          base.DisposeManagedResources();
        }
    }

    protected override void DisposeUnmanagedResources()
    {
        try
        {
          Console.WriteLine("A_DisposeUnmanagedResources");
          CloseHandle(handle_a);
          handle_a = IntPtr.Zero;
        }
        finally
        { 
          base.DisposeUnmanagedResources();
        }
    }
}

public class B : A
{
    public Component components_b { get; set; }
    private IntPtr handle_b;

    protected override void DisposeManagedResources()
    {
        try
        {
          Console.WriteLine("B_DisposeManagedResources");
          components_b.Dispose();
          components_b = null;
        }
        finally
        { 
          base.DisposeManagedResources();
        }
    }

    protected override void DisposeUnmanagedResources()
    {
        try
        {
          Console.WriteLine("B_DisposeUnmanagedResources");
          CloseHandle(handle_b);
          handle_b = IntPtr.Zero;
        }
        finally
        { 
          base.DisposeUnmanagedResources();
        }
    }
}

Stored procedures can be executed like below

 string cmd = Constants.StoredProcs.usp_AddRoles.ToString() + " @userId, @roleIdList";
                        int result = db.Database
                                       .ExecuteSqlCommand
                                       (
                                          cmd,
                                           new SqlParameter("@userId", userId),
                                           new SqlParameter("@roleIdList", roleId)
                                       );

Imagine you have

<div class="wrap">
    <img src="#">
</div>

And css:

.wrap {
    display: flex;
}
.wrap img {
    object-fit: contain;
}

Much simpler solution:

pd.DataFrame(df2["teams"].to_list(), columns=['team1', 'team2'])

Yields,

  team1 team2
-------------
0    SF   NYG
1    SF   NYG
2    SF   NYG
3    SF   NYG
4    SF   NYG
5    SF   NYG
6    SF   NYG
7    SF   NYG

If you wanted to split a column of delimited strings rather than lists, you could similarly do:

pd.DataFrame(df["teams"].str.split('<delim>', expand=True).values,
             columns=['team1', 'team2'])

Friends are also useful for callbacks. You could implement callbacks as static methods

class MyFoo
{
private:
    static void callback(void * data, void * clientData);
    void localCallback();
    ...
};

where callback calls localCallback internally, and the clientData has your instance in it. In my opinion,

or...

class MyFoo
{
    friend void callback(void * data, void * callData);
    void localCallback();
}

What this allows is for the friend to be a defined purely in the cpp as a c-style function, and not clutter up the class.

Similarly, a pattern I've seen very often is to put all the really private members of a class into another class, which is declared in the header, defined in the cpp, and friended. This allows the coder to hide a lot of the complexity and internal working of the class from the user of the header.

In the header:

class MyFooPrivate;
class MyFoo
{
    friend class MyFooPrivate;
public:
    MyFoo();
    // Public stuff
private:
    MyFooPrivate _private;
    // Other private members as needed
};

In the cpp,

class MyFooPrivate
{
public:
   MyFoo *owner;
   // Your complexity here
};

MyFoo::MyFoo()
{
    this->_private->owner = this;
}

It becomes easier to hide things that the downstream needn't see this way.

To execute the stored procedures, use FromSql method which executes RAW SQL queries

e.g.

    var products= context.Products
        .FromSql("EXECUTE dbo.GetProducts")
        .ToList();

To use with parameters

    var productCategory= "Electronics";

    var product = context.Products
        .FromSql("EXECUTE dbo.GetProductByCategory {0}", productCategory)
        .ToList();

or

    var productCategory= new SqlParameter("productCategory", "Electronics");

    var product = context.Product
        .FromSql("EXECUTE dbo.GetProductByName  @productCategory", productCategory)
        .ToList();

There are certain limitations to execute RAW SQL queries or stored procedures. You can’t use it for INSERT/UPDATE/DELETE. if you want to execute INSERT, UPDATE, DELETE queries, use the ExecuteSqlCommand

    var categoryName = "Electronics";
    dataContext.Database
               .ExecuteSqlCommand("dbo.InsertCategory @p0", categoryName);

If you develop in Visual Studio 2013 and 2015 versions, you can use their GPU Usage tool:

• GPU Usage Tool in Visual Studio (video) https://www.youtube.com/watch?v=Gjc5bPXGkTE
• GPU Usage Visual Studio 2015 https://msdn.microsoft.com/en-us/library/mt126195.aspx
• GPU Usage tool in Visual Studio 2013 Update 4 CTP1 (blog) http://blogs.msdn.com/b/vcblog/archive/2014/09/05/gpu-usage-tool-in-visual-studio-2013-update-4-ctp1.aspx
• GPU Usage for DirectX in Visual Studio (blog) http://blogs.msdn.com/b/ianhu/archive/2014/12/16/gpu-usage-for-directx-in-visual-studio.aspx

Screenshot from MSDN:

Moreover, it seems you can diagnose any application with it, not only Visual Studio Projects:

In addition to Visual Studio projects you can also collect GPU usage data on any loose .exe applications that you have sitting around. Just open the executable as a solution in Visual Studio and then start up a diagnostics session and you can target it with GPU usage. This way if you are using some type of engine or alternative development environment you can still collect data on it as long as you end up with an executable.

You could modify a PDF renderer such as xpdf or evince to render into a graphics image on your server, and then deliver the image to the user. This is how Google's quick view of PDF files works, they render it locally, then deliver images to the user. No downloaded PDF file, and the source is pretty well obscured. :)

<xsl:variable name="upper">UPPER CASE</xsl:variable>
<xsl:variable name="lower" select="translate($upper,'ABCDEFGHIJKLMNOPQRSTUVWXYZ', 'abcdefghijklmnopqrstuvwxyz')"/>
<xsl:value-of select ="$lower"/>

//displays UPPER CASE as upper case

Do it like this:

Parentdivimage should have specified width and height, and its position should be:

position: relative;

Just inside the parentdivimage, next to other divs that parent contains you should put:

<a href="linkt.to.smthn.com"><span class="clickable"></span></a>

Then in css file:

.clickable {
  height: 100%;
  width: 100%;
  left: 0;
  top: 0;
  position: absolute;     
  z-index: 1;
}

The span tag will fill out its parent block which is parentdiv, because of height and width set to 100%. Span will be on the top of all of surrounding elements because of setting z-index higher than other elements. Finally span will be clickable, because it's inside of an 'a' tag.

According to the great book "Effective Java":

Item 4: Enforce noninstantiability with a private constructor

- Attempting to enforce noninstantiability by making a class abstract does not work.

- A default constructor is generated only if a class contains no explicit constructors, so a class can be made noninstantiable by including a private constructor:

// Noninstantiable utility class
public class UtilityClass
{
    // Suppress default constructor for noninstantiability
    private UtilityClass() {
        throw new AssertionError();
    }
}

Because the explicit constructor is private, it is inaccessible outside of the class. The AssertionError isn’t strictly required, but it provides insurance in case the constructor is accidentally invoked from within the class. It guarantees that the class will never be instantiated under any circumstances. This idiom is mildly counterintuitive, as the constructor is provided expressly so that it cannot be invoked. It is therefore wise to include a comment, as shown above.

As a side effect, this idiom also prevents the class from being subclassed. All constructors must invoke a superclass constructor, explicitly or implicitly, and a subclass would have no accessible superclass constructor to invoke.

    import java.util.Scanner;

    public class LeapYear {
    public static void main(String[] args) {
        // TODO Auto-generated method stub
        Scanner input = new Scanner(System.in);
        System.out.print("Enter the year then press Enter : ");
        int year = input.nextInt();

        if ((year < 1580) && (year % 4 == 0)) {
            System.out.println("Leap year: " + year);
        } else {
            if ((year % 4 == 0) && (year % 100 != 0) || (year % 400 == 0)) {
                System.out.println("Leap year: " + year);
            } else {
                System.out.println(year + " not a leap year!");
            }

        }
    }
}

See os.path module for some useful functions on pathnames. To check if an existing file is executable, use os.access(path, mode), with the os.X_OK mode.

os.X_OK

Value to include in the mode parameter of access() to determine if path can be executed.

EDIT: The suggested which() implementations are missing one clue - using os.path.join() to build full file names.

You could use javascript. The other answers to date seem to also target Safari.

if (navigator.userAgent.toLowerCase().indexOf('chrome') > -1) {
    alert("You'll only see this in Chrome");
    $('#someID').css('background-position', '10px 20px');
}

.center {
  margin: auto;
  margin-top: 15vh;
}

Should do the trick

When you press enter in a form the natural behaviour of form is to being submited, to stop this behaviour which is not natural, you have to prevent it from submiting( default behaviour), with jquery:

$("#yourFormId").on("submit",function(event){event.preventDefault()})

If you are using ES6 in Node 4, you cannot use ES6 module syntax without a transpiler, but CommonJS modules (Node's standard modules) work the same.

module.export.AspectType

should be

module.exports.AspectType

hence the error message "Cannot set property 'AspectType' of undefined" because module.export === undefined.

Also, for

var AspectType = class AspectType {
    // ...    
};

can you just write

class AspectType {
    // ...    
}

and get essentially the same behavior.

You can use org.modeshape.common.text.Inflector.

Specifically:

String camelCase(String lowerCaseAndUnderscoredWord,
    boolean uppercaseFirstLetter, char... delimiterChars) 

By default, this method converts strings to UpperCamelCase.

Maven artifact is: org.modeshape:modeshape-common:2.3.0.Final

on JBoss repository: https://repository.jboss.org/nexus/content/repositories/releases

Here's the JAR file: https://repository.jboss.org/nexus/content/repositories/releases/org/modeshape/modeshape-common/2.3.0.Final/modeshape-common-2.3.0.Final.jar

Why not try MySQL GUI Tools? It's light, and does its job well.

Though nearly the same as most of the other responses, I think this is the most efficient and concise way to implement it. Using TryGetValue is faster than using ContainsKey and reindexing into the dictionary as some other solutions have shown.

void Add(string key, string val)
{
    List<string> list;

    if (!dictionary.TryGetValue(someKey, out list))
    {
       values = new List<string>();
       dictionary.Add(key, list);
    }

    list.Add(val);
}

This is how I solved the problem:

In main.js of the 'request' module I added one line:

Request.prototype.request = function () {
  var self = this
  self.setMaxListeners(0); // Added line

This defines unlimited listeners http://nodejs.org/docs/v0.4.7/api/events.html#emitter.setMaxListeners

In my code I set the 'maxRedirects' value explicitly:

var options = {uri:headingUri, headers:headerData, maxRedirects:100};

if you handel this from dataBase try :

<img :src="baseUrl + 'path/path' + obj.key +'.png'">

I wrote a tutorial about this a while ago.

The most important point is the "Site URL":

Site URL: http://localhost/app_name/

Where the folder structure is something like:

app_name
¦   index.php
¦
+---canvas
¦   ¦   index.php
¦   ¦
¦   +---css
¦           main.css
¦           reset.css
¦
+---src
        facebook.php
        fb_ca_chain_bundle.crt

EDIT:
Kavya: how does the FB server recognize my localhost even without an IP or port??

I don't think this has anything to do with Facebook, I guess since the iframe src parameter is loaded from client-side it'll treat your local URL as if you put it directly on your browser.

For example have a file on your online server with content (e.g. online.php):

<iframe src="http://localhost/test.php" width="100%" height="100%">
    <p>Not supported!</p>
</iframe>

And on your localhost root directory, have the file test.php:

<?php echo "Hello from Localhost!"; ?>

Now visit http://your_domain.com/online.php you will see your localhost file's content!

This is why realtime subscriptions and deauthorize callbacks (just to mention) won't work with localhost URLs! because Facebook will ping (send http requests) to these URLs but obviously Facebook server won't translate those URLs to yours!

The content is put after the HTTP headers. The format of an HTTP POST is to have the HTTP headers, followed by a blank line, followed by the request body. The POST variables are stored as key-value pairs in the body.

You can see this in the raw content of an HTTP Post, shown below:

POST /path/script.cgi HTTP/1.0
From: [email protected]
User-Agent: HTTPTool/1.0
Content-Type: application/x-www-form-urlencoded
Content-Length: 32

home=Cosby&favorite+flavor=flies

You can see this using a tool like Fiddler, which you can use to watch the raw HTTP request and response payloads being sent across the wire.

How about using csplit?

man csplit
csplit -k file 1 '{1}'

On the following option:

WebElement option = select.getFirstSelectedOption();
option.getText();

If from the method getText() you get a blank, you can get the string from the value of the option using the method getAttribute:

WebElement option = select.getFirstSelectedOption();
option.getAttribute("value");

Building off of @gnovice's answer, you can actually create filled plots with shading only in the area between the two curves. Just use fill in conjunction with fliplr.

Example:

x=0:0.01:2*pi;                  %#initialize x array
y1=sin(x);                      %#create first curve
y2=sin(x)+.5;                   %#create second curve
X=[x,fliplr(x)];                %#create continuous x value array for plotting
Y=[y1,fliplr(y2)];              %#create y values for out and then back
fill(X,Y,'b');                  %#plot filled area

By flipping the x array and concatenating it with the original, you're going out, down, back, and then up to close both arrays in a complete, many-many-many-sided polygon.

I doubt for Keys.TAB in sendKeys method... if you want to use TAB you need to do something like below:

Actions builder = new Actions(driver);
builder.keyDown(Keys.TAB).perform()

Here are three ways you can check if dict is empty. I prefer using the first way only though. The other two ways are way too wordy.

test_dict = {}

if not test_dict:
    print "Dict is Empty"


if not bool(test_dict):
    print "Dict is Empty"


if len(test_dict) == 0:
    print "Dict is Empty"

In your client SOAP handler you need to set javax.xml.ws.security.auth.username and javax.xml.ws.security.auth.password property as follow:

public class ClientHandler implements SOAPHandler<SOAPMessageContext>{

    public boolean handleMessage(final SOAPMessageContext soapMessageContext)
    {
        final Boolean outInd = (Boolean)soapMessageContext.get(MessageContext.MESSAGE_OUTBOUND_PROPERTY);
        if (outInd.booleanValue())
        {
          try 
          {
               soapMessageContext.put("javax.xml.ws.security.auth.username", <ClientUserName>);
               soapMessageContext.put("javax.xml.ws.security.auth.password", <ClientPassword>);
          } 
          catch (Exception e)
          {
               e.printStackTrace();
               return false;
          }
         }
      return true;
     }
}

You should use the flex or flex-basis property rather than width. Read more on MDN.

.flexbox .red {
  flex: 0 0 25em;
}

The flex CSS property is a shorthand property specifying the ability of a flex item to alter its dimensions to fill available space. It contains:

flex-grow: 0;     /* do not grow   - initial value: 0 */
flex-shrink: 0;   /* do not shrink - initial value: 1 */
flex-basis: 25em; /* width/height  - initial value: auto */

A simple demo shows how to set the first column to 50px fixed width.

.flexbox {_x000D_
  display: flex;_x000D_
}_x000D_
.red {_x000D_
  background: red;_x000D_
  flex: 0 0 50px;_x000D_
}_x000D_
.green {_x000D_
  background: green;_x000D_
  flex: 1;_x000D_
}_x000D_
.blue {_x000D_
  background: blue;_x000D_
  flex: 1;_x000D_
}

<div class="flexbox">_x000D_
  <div class="red">1</div>_x000D_
  <div class="green">2</div>_x000D_
  <div class="blue">3</div>_x000D_
</div>

You have the noclobber option set. The error looks like it's from csh, so you would do:

cat /dev/null >! file

If I'm wrong and you are using bash, you should do:

cat /dev/null >| file

in bash, you can also shorten that to:

>| file

In my case a has to add my classes, when building the SessionFactory, with addAnnotationClass

Configuration configuration.configure();
StandardServiceRegistryBuilder builder = new StandardServiceRegistryBuilder().applySettings(configuration.getProperties());
SessionFactory sessionFactory = configuration
            .addAnnotatedClass(MyEntity1.class)
            .addAnnotatedClass(MyEntity2.class)
            .buildSessionFactory(builder.build());

just remove class 'fade' from modal

I use Ude that is a C# port of Mozilla Universal Charset Detector. It is easy to use and gives some really good results.

If you use ONLY Internet Explorer, you can use this:

<input type="text" id="myID" onpropertychange="TextChange(this)" />

<script type="text/javascript">
    function TextChange(tBox) {
        if(event.propertyName=='value') {
            //your code here
        }
    }
</script>

Hope that helps.

I would stick with the $null check since any value other than '' (empty string), 0, $false and $null will pass the check: if ($ie) {...}.

How many people sad above, there are a lot of plugins to gradle execute a by pass in this problem like:

plugins {
  id "ua.eshepelyuk.ManifestClasspath" version "1.0.0"
}

or

plugins {
  id "com.github.ManifestClasspath" version "0.1.0-RELEASE"
}

But the better solution that I found was kill the JVM process and everything is done.

If you just want to know the number, rather than get it in a query then you can use:

SHOW CREATE TABLE tablename;

You should see the auto_increment at the bottom

Maybe you can use this code (in C#):

long Kb = 1024;
long Mb = Kb * 1024;
long Gb = Mb * 1024;
long Tb = Gb * 1024;
long Pb = Tb * 1024;
long Eb = Pb * 1024;

if (size < Kb)  return size.ToString() + " byte";

if (size < Mb)  return (size / Kb).ToString("###.##") + " Kb.";
if (size < Gb)  return (size / Mb).ToString("###.##") + " Mb.";
if (size < Tb)  return (size / Gb).ToString("###.##") + " Gb.";
if (size < Pb)  return (size / Tb).ToString("###.##") + " Tb.";
if (size < Eb)  return (size / Pb).ToString("###.##") + " Pb.";
if (size >= Eb) return (size / Eb).ToString("###.##") + " Eb.";

return "invalid size";

Had same experience, however what did the magic for me is not to change embed to v.

So the code will look like this...

<iframe width="560" height="315" src="https://www.youtube.com/embed/cTYuscQu-Og?Version=3&loop=1&playlist=cTYuscQu-Og" frameborder="0" allowfullscreen></iframe>

Hope it helps...

I found this resizer to work better:

function resizer(id)
{

    var doc = document.getElementById(id).contentWindow.document;
    var body_ = doc.body;
    var html_ = doc.documentElement;

    var height = Math.max( body_.scrollHeight, body_.offsetHeight, html_.clientHeight,     html_.scrollHeight, html_.offsetHeight );
    var width  = Math.max( body_.scrollWidth, body_.offsetWidth, html_.clientWidth, html_.scrollWidth, html_.offsetWidth );

    document.getElementById(id).height = height;
    document.getElementById(id).width = width;

}

Note the style object is removed.

EDIT:
Just saw you edited the question to say that you don't want to use friend.
Then the answer is:

NO you can't, atleast not in a portable way approved by the C++ standard.

The later part of the Answer, was previous to the Q edit & I leave it here for benefit of >those who would want to understand a few concepts & not just looking an Answer to the >Question.

If you have members under a Private access specifier then those members are only accessible from within the class. No outside Access is allowed.

An Source Code Example:

class MyClass
{
    private:
        int c;
    public:
    void doSomething()
    {
        c = 10;    //Allowed 
    }
};

int main()
{
    MyClass obj;
    obj.c = 30;     //Not Allowed, gives compiler error
    obj.doSomething();  //Allowed
}

A Workaround: friend to rescue
To access the private member, you can declare a function/class as friend of that particular class, and then the member will be accessible inside that function or class object without access specifier check.

Modified Code Sample:

class MyClass
{
    private:
        int c;

    public:
    void doSomething()
    {
        c = 10;    //Allowed 
    }

    friend void MytrustedFriend();    
};

void MytrustedFriend()
{
        MyClass obj;
        obj.c = 10; //Allowed
}

int main()
{
    MyClass obj;
    obj.c = 30;     //Not Allowed, gives compiler error
    obj.doSomething();  //Allowed
    //Call the friend function
    MytrustedFriend();
    return 0;
}

use this

if (userProfile.AccountType == AccountType.Retailer)
{
     ...
}

If you want to get int from your AccountType enum and compare it (don't know why) do this:

if((int)userProfile.AccountType == 1)
{ 
     ...
}

Objet reference not set to an instance of an object exception is because your userProfile is null and you are getting property of null. Check in debug why it's not set.

EDIT (thanks to @Rik and @KonradMorawski) :

Maybe you can do some check before:

if(userProfile!=null)
{
}

or

if(userProfile==null)
{
   throw new ArgumentNullException(nameof(userProfile)); // or any other exception
}

This code works for all cases include other chars not only parentheses ex:
Please enter input

{ibrahim[k]}
true

()[]{}[][]
true saddsd] false

public class Solution {

    private static Map<Character, Character> parenthesesMapLeft = new HashMap<>();
    private static Map<Character, Character> parenthesesMapRight = new HashMap<>();

    static {
        parenthesesMapLeft.put('(', '(');
        parenthesesMapRight.put(')', '(');
        parenthesesMapLeft.put('[', '[');
        parenthesesMapRight.put(']', '[');
        parenthesesMapLeft.put('{', '{');
        parenthesesMapRight.put('}', '{');
    }

    public static void main(String[] args) {
        System.out.println("Please enter input");
        Scanner scanner = new Scanner(System.in);

        String str = scanner.nextLine();

        System.out.println(isBalanced(str));
    }

    public static boolean isBalanced(String str) {

        boolean result = false;
        if (str.length() < 2)
            return false;
        Stack<Character> stack = new Stack<>();
        for (int i = 0; i < str.length(); i++) {

            char ch = str.charAt(i);
            if (!parenthesesMapRight.containsKey(ch) && !parenthesesMapLeft.containsKey(ch)) {
                continue;
            }
            if (parenthesesMapLeft.containsKey(ch)) {
                stack.push(ch);
            } else {
                if (!stack.isEmpty() && stack.pop() == parenthesesMapRight.get(ch).charValue()) {
                    result = true;
                } else {
                    return false;
                }
            }

        }
        if (!stack.isEmpty())
            return result = false;
        return result;
    }
}

You have a few options, all varying in "correctness" and ease of use. As always, the right design depends on your needs.

• You could simply create two columns in Ticket, OwnedByUserId and OwnedByGroupId, and have nullable Foreign Keys to each table.

• You could create M:M reference tables enabling both ticket:user and ticket:group relationships. Perhaps in future you will want to allow a single ticket to be owned by multiple users or groups? This design does not enforce that a ticket must be owned by a single entity only.

• You could create a default group for every user and have tickets simply owned by either a true Group or a User's default Group.

• Or (my choice) model an entity that acts as a base for both Users and Groups, and have tickets owned by that entity.

Heres a rough example using your posted schema:

create table dbo.PartyType
(   
    PartyTypeId tinyint primary key,
    PartyTypeName varchar(10)
)

insert into dbo.PartyType
    values(1, 'User'), (2, 'Group');


create table dbo.Party
(
    PartyId int identity(1,1) primary key,
    PartyTypeId tinyint references dbo.PartyType(PartyTypeId),
    unique (PartyId, PartyTypeId)
)

CREATE TABLE dbo.[Group]
(
    ID int primary key,
    Name varchar(50) NOT NULL,
    PartyTypeId as cast(2 as tinyint) persisted,
    foreign key (ID, PartyTypeId) references Party(PartyId, PartyTypeID)
)  

CREATE TABLE dbo.[User]
(
    ID int primary key,
    Name varchar(50) NOT NULL,
    PartyTypeId as cast(1 as tinyint) persisted,
    foreign key (ID, PartyTypeId) references Party(PartyID, PartyTypeID)
)

CREATE TABLE dbo.Ticket
(
    ID int primary key,
    [Owner] int NOT NULL references dbo.Party(PartyId),
    [Subject] varchar(50) NULL
)

The Problem

When an element is floated, its parent no longer contains it because the float is removed from the flow. The floated element is out of the natural flow, so all block elements will render as if the floated element is not even there, so a parent container will not fully expand to hold the floated child element.

Take a look at the following article to get a better idea of how the CSS Float property works:

The Mystery Of The CSS Float Property

A Potential Solution

Now, I think the following article resembles what you're trying to do. Take a look at it and see if you can solve your problem.

Equal Height Columns with Cross-Browser CSS

I hope this helps.

Most likely there is an error somewhere in the get_profile() call. In your view, before you return the request object, put this line:

request.user.get_profile()

It should raise the error, and give you a more detailed traceback, which you can then use to further debug.

If you want to examine elements inside a dataframe you should not be using ls() which only looks at the names of objects in the current workspace (or if used inside a function in the current environment). Rownames or elements inside such objects are not visible to ls() (unless of course you add an environment argument to the ls(.)-call). Try using grep() which is the workhorse function for pattern matching of character vectors:

result <- a[ grep("blue", a$x) , ]  # Note need to use `a$` to get at the `x`

If you want to use subset then consider the closely related function grepl() which returns a vector of logicals can be used in the subset argument:

subset(a, grepl("blue", a$x))
      x
2 blue1
3 blue2

Edit: Adding one "proper" use of glob2rx within subset():

result <- subset(a,  grepl(glob2rx("blue*") , x) )
result
      x
2 blue1
3 blue2

I don't think I actually understood glob2rx until I came back to this question. (I did understand the scoping issues that were ar the root of the questioner's difficulties. Anybody reading this should now scroll down to Gavin's answer and upvote it.)

Looks like people like doing spoonfeeding, so I have decided to post the worst solution to an easy task:

public static boolean isNumber(String s) throws Exception {
    boolean result = false;
    byte[] bytes = s.getBytes("ASCII");
    int tmp, i = bytes.length;
    while (i >0  && (result = ((tmp = bytes[--i] - '0') >= 0) && tmp <= 9));
    return result;
}

About the worst code I could imagine, but there might be other people here who can come up with even worse solutions.

Hm, containsNumber is worse:

public static boolean containsNumber(String s) throws Exception {
    boolean result = false;
    byte[] bytes = s.getBytes("ASCII");
    int tmp, i = bytes.length;
    while (i >0  && (true | (result |= ((tmp = bytes[--i] - '0') >= 0) && tmp <= 9)));

Just use Apache commons upload library. Add URIEncoding="UTF-8" to Tomcat's connector, and use FileItem.getString("UTF-8") instead of FileItem.getString() without charset specified.

Hope this help.

Well, you can do css tables instead of html tables. This keeps your html semantically correct, but allows you to use tables for layout purposes.

This seems to make more sense than using float hacks.

<html>
  <head>
    <style>

#content-wrapper{
  display:table;
}

#content{
  display:table-row;
}

#content>div{
  display:table-cell
}

/*adding some extras for demo purposes*/
#content-wrapper{
  width:100%;
  height:100%;
  top:0px;
  left:0px;
  position:absolute;
}
#nav{
  width:100px;
  background:yellow;
}
#body{
  background:blue;
}
</style>

  </head>
  <body>
    <div id="content-wrapper">
      <div id="content">
        <div id="nav">
          Left hand content
        </div>
        <div id="body">
          Right hand content
        </div>
      </div>
    </div>
  </body>
</html>

Easier and more updated way is:

1. Use ps -ef | grep postgres to find the connection #
2. sudo kill -9 "#" of the connection

Note: There may be identical PID. Killing one kills all.

No, the <select> control is a system-level control, not a client-level control in IE. A few versions back it didn't even play nicely-with z-index, putting itself on top of virtually everything.

To do anything fancy you'll have to emulate the functionality using CSS and your own elements.

You cannot do this:

vector<string> name(5); //error in these 2 lines
vector<int> val(5,0);

in a class outside of a method.

You can initialize the data members at the point of declaration, but not with () brackets:

class Foo {
    vector<string> name = vector<string>(5);
    vector<int> val{vector<int>(5,0)};
};

Before C++11, you need to declare them first, then initialize them e.g in a contructor

class Foo {
    vector<string> name;
    vector<int> val;
 public:
  Foo() : name(5), val(5,0) {}
};

2 GB by default. If the application is large address space aware (linked with /LARGEADDRESSAWARE), it gets 4 GB (not 3 GB, see http://msdn.microsoft.com/en-us/library/aa366778.aspx)

They're still limited to 2 GB since many application depends on the top bit of pointers to be zero.

Thanks for the really useful script.

You may need to add the following modification to the code if your tables have non-convertable fields:

SET @ColumnName =
    (
        SELECT MIN(QUOTENAME(COLUMN_NAME))
        FROM    INFORMATION_SCHEMA.COLUMNS
        WHERE       TABLE_SCHEMA    = PARSENAME(@TableName, 2)
            AND TABLE_NAME  = PARSENAME(@TableName, 1)
            AND DATA_TYPE NOT IN ('text', 'image', 'ntext')                 
            AND QUOTENAME(COLUMN_NAME) > @ColumnName
    )

In openCV's documentation there is an example for getting video frame by frame. It is written in c++ but it is very easy to port the example to python - you can search for each fumction documentation to see how to call them in python.

#include "opencv2/opencv.hpp"

using namespace cv;

int main(int, char**)
{
    VideoCapture cap(0); // open the default camera
    if(!cap.isOpened())  // check if we succeeded
        return -1;

    Mat edges;
    namedWindow("edges",1);
    for(;;)
    {
        Mat frame;
        cap >> frame; // get a new frame from camera
        cvtColor(frame, edges, CV_BGR2GRAY);
        GaussianBlur(edges, edges, Size(7,7), 1.5, 1.5);
        Canny(edges, edges, 0, 30, 3);
        imshow("edges", edges);
        if(waitKey(30) >= 0) break;
    }
    // the camera will be deinitialized automatically in VideoCapture destructor
    return 0;
}

To make this work on Ubuntu Linux:

1. I installed the Ubuntu package ruby-json:

   apt-get install ruby-json
   

2. I wrote the script in ${HOME}/rubybin/jsonDEMO

3. $HOME/.bashrc included:

   ${HOME}/rubybin:${PATH}
   

(On this occasion I also typed the above on the bash command line.)

Then it worked when I entered on the command line:

jsonDemo

I am using the Spring framework's RestTemplate in my client programme and, at the server-side, I defined a GET request with a Json body. My primary purpose is the same as yours: when the request has numerous parameters, putting them in the body seems tidier than putting them in the prolonged URI string. Yes?

But, sadly, it's not working! The server-side threw the following exception:

org.springframework.http.converter.HttpMessageNotReadableException: Required request body is missing...

But I am pretty sure the message body is correctly provided by my client code, so what's wrong?

I traced into the RestTemplate.exchange() method and found the following:

// SimpleClientHttpRequestFactory.class
public class SimpleClientHttpRequestFactory implements ClientHttpRequestFactory, AsyncClientHttpRequestFactory {
    ...
    protected void prepareConnection(HttpURLConnection connection, String httpMethod) throws IOException {
        ...
        if (!"POST".equals(httpMethod) && !"PUT".equals(httpMethod) && !"PATCH".equals(httpMethod) && !"DELETE".equals(httpMethod)) {
            connection.setDoOutput(false);
        } else {
            connection.setDoOutput(true);
        }
        ...
    }
}

// SimpleBufferingClientHttpRequest.class
final class SimpleBufferingClientHttpRequest extends AbstractBufferingClientHttpRequest {
    ...
    protected ClientHttpResponse executeInternal(HttpHeaders headers, byte[] bufferedOutput) throws IOException {
        ...
        if (this.connection.getDoOutput() && this.outputStreaming) {
            this.connection.setFixedLengthStreamingMode(bufferedOutput.length);
        }

        this.connection.connect();
        if (this.connection.getDoOutput()) {
            FileCopyUtils.copy(bufferedOutput, this.connection.getOutputStream());
        } else {
            this.connection.getResponseCode();
        }
        ...
    }
}

Please notice that in the executeInternal() method, the input argument 'bufferedOutput' contains the message body provided by my code. I saw it through the debugger.

However, due to the prepareConnection(), the getDoOutput() in executeInternal() always returns false which, in turn, makes the bufferedOutput completely ignored! It's not copied into the output stream.

Consequently, my server programme received no message body and threw that exception.

This is an example about the RestTemplate of the Spring framework. The point is that, even if the message body is no longer forbidden by the HTTP spec, some client or server libraries or frameworks might still comply with the old spec and reject the message body from the GET request.

I had the same problem, in my case i resolved it by:

1) going to File-->Project Structure---->Global libraries 2) looking for jfxrt.jar included as default in the jdk1.8.0_241\lib (after installing it) 3)click on + on top left to add new global library and i specified the path of my jdk1.8.0_241 Ex :(C:\Program Files\Java\jdk1.8.0_241).

I hope this will help you

It's possible to do this without using extra JS code using the data-collapse and data-target attributes on the a link.

e.g.

<a class="btn" data-toggle="collapse" data-target="#viewdetails">View details &raquo;</a>

Here's a working example.

i solved with a max-width in my main css-file.

/* Set width on the form input elements since they're 100% wide by default */
input,
select,
textarea {
    max-width: 280px;
}

It's a simple solution with little "code"
