As of Java 7 (and Android API level 19):

System.lineSeparator()

Documentation: Java Platform SE 7

For older versions of Java, use:

System.getProperty("line.separator");

See https://java.sun.com/docs/books/tutorial/essential/environment/sysprop.html for other properties.

You can load your External JS files in Angular and you can load them directly instead of defining in index.html file.

component.ts:

ngOnInit() {
    this.loadScripts();
}


  loadScripts() {
    const dynamicScripts = [
      //scripts to be loaded
      "assets/lib/js/hand-1.3.8.js",
      "assets/lib/js/modernizr.jr.js",
      "assets/lib/js/jquery-2.2.3.js",
      "assets/lib/js/jquery-migrate-1.4.1.js",
      "assets/js/jr.utils.js"
    ];
    for (let i = 0; i < dynamicScripts.length; i++) {
      const node = document.createElement('script');
      node.src = dynamicScripts[i];
      node.type = 'text/javascript';
      node.async = false;
      document.getElementById('scripts').appendChild(node);
    }
  }

component.html:

<div id="scripts">
</div>

You can also load styles similarly.

component.ts:

ngOnInit() {
    this.loadStyles();
}


  loadStyles() {
    const dynamicStyles = [
      //styles to be loaded
      "assets/lib/css/ui.css",
      "assets/lib/css/material-theme.css",
      "assets/lib/css/custom-style.css"
    ];
    for (let i = 0; i < dynamicStyles.length; i++) {
      const node = document.createElement('link');
      node.href = dynamicStyles[i];
      node.rel = 'stylesheet';
      document.getElementById('styles').appendChild(node);
    }
  }

component.html:

<div id="styles">
</div>

[[NSDate date] timeIntervalSince1970];

It returns the number of seconds since epoch as a double. I'm almost sure you can access the milliseconds from the fractional part.

You cannot create different "variable names" but you can create different object properties. There are many ways to do whatever it is you're actually trying to accomplish. In your case I would just do

for (var i = myArray.length - 1; i >= 0; i--) {    console.log(eval(myArray[i])); }; 

More generally you can create object properties dynamically, which is the type of flexibility you're thinking of.

var result = {}; for (var i = myArray.length - 1; i >= 0; i--) {     result[myArray[i]] = eval(myArray[i]);   }; 

I'm being a little handwavey since I don't actually understand language theory, but in pure Javascript (including Node) references (i.e. variable names) are happening at a higher level than at runtime. More like at the call stack; you certainly can't manufacture them in your code like you produce objects or arrays. Browsers do actually let you do this anyway though it's terrible practice, via

window['myVarName'] = 'namingCollisionsAreFun';  

(per comment)

I don't know why but for me the solution proposed by Marius Stanescu is breaking the specificity of col (a col-md-3 followed by a col-md-4 will take all of the twelve row)

I found another working solution :

.bottom-column 
{
   display: inline-block;
   vertical-align: middle;
   float: none;
}

To select all characters except the last n from a string (or put another way, remove last n characters from a string); use the SUBSTRING and CHAR_LENGTH functions together:

SELECT col
     , /* ANSI Syntax  */ SUBSTRING(col FROM 1 FOR CHAR_LENGTH(col) - 2) AS col_trimmed
     , /* MySQL Syntax */ SUBSTRING(col,     1,    CHAR_LENGTH(col) - 2) AS col_trimmed
FROM tbl

To remove a specific substring from the end of string, use the TRIM function:

SELECT col
     , TRIM(TRAILING '.php' FROM col)
-- index.php becomes index
-- index.txt remains index.txt

So, for future reference for anybody who doesn't want to spend two days searching the internet to figure this out, when you encode byte arrays into QR Codes, you have to use the ISO-8859-1character set, not UTF-8.

Use prop() for updating the hidden property, and change() for handling the change event.

$('#check').change(function() {_x000D_
  $("#delete").prop("hidden", !this.checked);_x000D_
})

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>_x000D_
<table>_x000D_
  <tr>_x000D_
    <td>_x000D_
      <input id="check" type="checkbox" name="del_attachment_id[]" value="<?php echo $attachment['link'];?>">_x000D_
    </td>_x000D_
_x000D_
    <td id="delete" hidden="true">_x000D_
      the file will be deleted from the newsletter_x000D_
    </td>_x000D_
  </tr>_x000D_
</table>

Like you, I cannot get MS Office Web Components to work. I would not consider Google Docs since Google seems to think they own anything that passes through their hands. I have tried MS Publish Objects but the quality of the generated html/css is truely awful.

The secret of converting an Excel worksheet to html that will display correctly on a smartphone is to create clean, lean html/css.

The structure of the HTML is:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Frameset//EN"
          "http://www.w3.org/TR/xhtml1/DTD/xhtml1-frameset.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
  <head><meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
    HEAD
  </head>
  <body>
    BODY
  </body>
</html>

There are useful html elements that can replace "HEAD" but it is not clear to me how you would generate them from an Excel worksheet. They would need to be added separately.

The obvious output for a worksheet or a range is an html table so the following assumes BODY will be replaced by an html table.

The structure of an html table is:

<table TABLE-ATTRIBUTES>
  <tr TABLE-ROW-ATTRIBUTES>
    <td TABLE-CELL-ATTRIBUTES>CELL-VALUE</td>
    More <td>...</td> elements as necessary
  </tr>
  More <tr>...</tr> as necessary
</table>  

Include as few TABLE-ATTRIBUTES, TABLE-ROW-ATTRIBUTES and TABLE-CELL-ATTRIBUTES as possible. Do not set column widths in pixels. Use css attributes rather than html attributes.

A table attribute worth considering is style = "border-collapse: collapse;". The default is separate with a gap around each cell. With collapse the cells touch as they do with Excel.

Three table attribute worth considering are style="background-color:aliceblue;", style="color:#0000FF;" and style="text-align:right;". With the first, you can specify the background colour to be any of the fifty or so named html colours. With the second, you can specify the font colour to be any of 256*256*256 colours. With the third you can right-align numeric values.

The above covers only a fraction of the formatting information that could be converted from Excel to html/css. I am developing an add-in that will convert as much Excel formatting as possible but I hope the above helps anyone with simple requirements.

Here's yet another way (using a negative look-ahead):

^/(?!ignoreme|ignoreme2|ignoremeN)([a-z0-9]+)$ 

Note: There's only one capturing expression: ([a-z0-9]+).

You can enable long path names using PowerShell:

Set-ItemProperty -Path 'HKLM:\SYSTEM\CurrentControlSet\Control\FileSystem' -Name LongPathsEnabled -Type DWord -Value 1 

Another Version is to use a Group Policy in Computer Configuration/Administrative Templates/System/Filesystem:

I know this is old, but came across it looking for a simpler way, and this is how i do it, just create a new list of the same object and add it to the one you want to use e.g.

Subject[] subjectsList = {new Subject1{....}, new Subject2{....}, new Subject3{....}} 
univStudent.subjects = subjectsList ;

In code to load a resource in the executing assembly where my image Freq.png was in the folder Icons and defined as Resource:

this.Icon = new BitmapImage(new Uri(@"pack://application:,,,/" 
    + Assembly.GetExecutingAssembly().GetName().Name 
    + ";component/" 
    + "Icons/Freq.png", UriKind.Absolute)); 

I also made a function:

/// <summary>
/// Load a resource WPF-BitmapImage (png, bmp, ...) from embedded resource defined as 'Resource' not as 'Embedded resource'.
/// </summary>
/// <param name="pathInApplication">Path without starting slash</param>
/// <param name="assembly">Usually 'Assembly.GetExecutingAssembly()'. If not mentionned, I will use the calling assembly</param>
/// <returns></returns>
public static BitmapImage LoadBitmapFromResource(string pathInApplication, Assembly assembly = null)
{
    if (assembly == null)
    {
        assembly = Assembly.GetCallingAssembly();
    }

    if (pathInApplication[0] == '/')
    {
        pathInApplication = pathInApplication.Substring(1);
    }
    return new BitmapImage(new Uri(@"pack://application:,,,/" + assembly.GetName().Name + ";component/" + pathInApplication, UriKind.Absolute)); 
}

Usage (assumption you put the function in a ResourceHelper class):

this.Icon = ResourceHelper.LoadBitmapFromResource("Icons/Freq.png");

Note: see MSDN Pack URIs in WPF:
pack://application:,,,/ReferencedAssembly;component/Subfolder/ResourceFile.xaml

The onload event does not always work on IE7/8 in <head> ... </head>

You can force it by adding an onload script at the end of your page before the tag as below.

  <script>
    window.onload();
  </script>
</body>

Type unset HOST in your terminal.

Use request.get_data() to get the raw data, regardless of content type. The data is cached and you can subsequently access request.data, request.json, request.form at will.

If you access request.data first, it will call get_data with an argument to parse form data first. If the request has a form content type (multipart/form-data, application/x-www-form-urlencoded, or application/x-url-encoded) then the raw data will be consumed. request.data and request.json will appear empty in this case.

The gacutil utility is not available on client machines, and the Window SDK license forbids redistributing it to your customers. When your customer can not, will not, (and really should not) download the 300MB Windows SDK as part of your application's install process.

There is an officially supported API you (or your installer) can use to register an assembly in the global assembly cache. Microsoft's Windows Installer technology knows how to call this API for you. You would have to consult your MSI installer utility (e.g. WiX, InnoSetup) for their own syntax of how to indicate you want an assembly to be registered in the Global Assembly Cache.

But MSI, and gacutil, are doing nothing special. They simply call the same API you can call yourself. For documentation on how to register an assembly through code, see:

KB317540: DOC: Global Assembly Cache (GAC) APIs Are Not Documented in the .NET Framework Software Development Kit (SDK) Documentation

var IAssemblyCache assemblyCache;
CreateAssemblyCache(ref assemblyCache, 0);


String manifestPath = "D:\Program Files\Contoso\Frobber\Grob.dll";

FUSION_INSTALL_REFERENCE refData;
refData.cbSize = SizeOf(refData); //The size of the structure in bytes
refData.dwFlags = 0; //Reserved, must be zero
refData.guidScheme = FUSION_REFCOUNT_FILEPATH_GUID; //The assembly is referenced by an application that is represented by a file in the file system. The szIdentifier field is the path to this file.
refData.szIdentifier = "D:\Program Files\Contoso\Frobber\SuperGrob.exe"; //A unique string that identifies the application that installed the assembly
refData.szNonCannonicalData = "Super cool grobber 9000"; //A string that is only understood by the entity that adds the reference. The GAC only stores this string

//Add a new assembly to the GAC. 
//The assembly must be persisted in the file system and is copied to the GAC.
assemblyCache.InstallAssembly(
      IASSEMBLYCACHE_INSTALL_FLAG_FORCE_REFRESH, //The files of an existing assembly are overwritten regardless of their version number
      manifestPath, //A string pointing to the dynamic-linked library (DLL) that contains the assembly manifest. Other assembly files must reside in the same directory as the DLL that contains the assembly manifest.
      refData);

More documentation before the KB article is deleted:

The fields of the structure are defined as follows:

• cbSize - The size of the structure in bytes.
• dwFlags - Reserved, must be zero.
• guidScheme - The entity that adds the reference.
• szIdentifier - A unique string that identifies the application that installed the assembly.
• szNonCannonicalData - A string that is only understood by the entity that adds the reference. The GAC only stores this string.

Possible values for the guidScheme field can be one of the following:

FUSION_REFCOUNT_MSI_GUID - The assembly is referenced by an application that has been installed by using Windows Installer. The szIdentifier field is set to MSI, and szNonCannonicalData is set to Windows Installer. This scheme must only be used by Windows Installer itself. FUSION_REFCOUNT_UNINSTALL_SUBKEY_GUID - The assembly is referenced by an application that appears in Add/Remove Programs. The szIdentifier field is the token that is used to register the application with Add/Remove programs. FUSION_REFCOUNT_FILEPATH_GUID - The assembly is referenced by an application that is represented by a file in the file system. The szIdentifier field is the path to this file. FUSION_REFCOUNT_OPAQUE_STRING_GUID - The assembly is referenced by an application that is only represented by an opaque string. The szIdentifier is this opaque string. The GAC does not perform existence checking for opaque references when you remove this.

Benchmarks

Firstly, you must decide on what you mean by "best" solution, of course that takes into account the efficiency of the algorithm, its readability/maintainability, and the likelihood of bugs creeping up in the future. Careful unit tests can generally avoid those problems, however.

I ran each of these examples 10 million times, and the results value is the number of ElapsedTicks that have passed.

Without further ado, from slowest to quickest, the algorithms are:

Install jupyter. Open terminal. Go to folder where you file is (in terminal ie.cd path/to/folder). Run jupyter notebook. And voila: you have something like this:

Notice that to open a notebook in the folder, you can either click on it in the browser or go to address:

http://localhost:8888/notebooks/name_of_your_file.ipynb

Give your button an id something like this:

<input id="mybutton" type="button" value="Dont show this again! " />

Then use jquery (to make this unobtrusive) and attach click action like so:

$(document).ready(function (){
    $('#mybutton').click(function (){
       fbLikeDump();
       WriteCookie();
    });
});

(this part should be in your .js file too)

I should have mentioned that you will need the jquery libraries on your page, so right before your closing body tag add these:

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
<script type="text/javascript" src="http://PATHTOYOURJSFILE"></script>

The reason to add just before body closing tag is for performance of perceived page loading times

This also happens if the paths are correct, but the service account is not the owner of the data files (yet it still has enough rights for read/write access). This can occur if the permissions for the files were reset to match the permissions of the folder (of course, while the service was stopped).

The easiest solution in this case is to detach each database and attach it again (because when attaching the owner is changed to be the service account).

You likely need to re-start VNC on both ends. i.e. when you say "restarted VNC", you probably just mean the client. But what about the other end? You likely need to re-start that end too. The root cause is likely a conflict. Many apps spy on the clipboard when they shouldn't. And many apps are not forgiving when they go to open the clipboard and can't. Robust ones will retry, others will simply not anticipate a failure and then they get fouled up and need to be restarted. Could be VNC, or it could be another app that's "listening" to the clipboard viewer chain, where it is obligated to pass along notifications to the other apps in the chain. If the notifications aren't sent, then VNC may not even know that there has been a clipboard update.

Use a long datatype.

I had the same problem, then I did this two steps:

• Enable "Allow less secure apps" on your google account security policy.
• Restart your local servers.

There are several solutions depending on what you need...

If you want to add a custom header (or set of headers) to an individual request then just add the headers property:

// Request with custom header
$.ajax({
    url: 'foo/bar',
    headers: { 'x-my-custom-header': 'some value' }
});

If you want to add a default header (or set of headers) to every request then use $.ajaxSetup():

$.ajaxSetup({
    headers: { 'x-my-custom-header': 'some value' }
});

// Sends your custom header
$.ajax({ url: 'foo/bar' });

// Overwrites the default header with a new header
$.ajax({ url: 'foo/bar', headers: { 'x-some-other-header': 'some value' } });

If you want to add a header (or set of headers) to every request then use the beforeSend hook with $.ajaxSetup():

$.ajaxSetup({
    beforeSend: function(xhr) {
        xhr.setRequestHeader('x-my-custom-header', 'some value');
    }
});

// Sends your custom header
$.ajax({ url: 'foo/bar' });

// Sends both custom headers
$.ajax({ url: 'foo/bar', headers: { 'x-some-other-header': 'some value' } });

Edit (more info): One thing to be aware of is that with ajaxSetup you can only define one set of default headers and you can only define one beforeSend. If you call ajaxSetup multiple times, only the last set of headers will be sent and only the last before-send callback will execute.

If you don't need to handle special shell characters in the array elements:

array=(a c b f 3 5)
sorted=($(printf '%s\n' "${array[@]}"|sort))

With bash you'll need an external sorting program anyway.

With zsh no external programs are needed and special shell characters are easily handled:

% array=('a a' c b f 3 5); printf '%s\n' "${(o)array[@]}" 
3
5
a a
b
c
f

ksh has set -s to sort ASCIIbetically.

You may want to look into using java's java.math.BigDecimal class if you really need precision math. Here is a good article from Oracle/Sun on the case for BigDecimal. While you can never represent 1/3 as someone mentioned, you can have the power to decide exactly how precise you want the result to be. setScale() is your friend.. :)

Ok, because I have way too much time on my hands at the moment here is a code example that relates to your question:

import java.math.BigDecimal;
/**
 * Created by a wonderful programmer known as:
 * Vincent Stoessel
 * [email protected]
 * on Mar 17, 2010 at  11:05:16 PM
 */
public class BigUp {

    public static void main(String[] args) {
        BigDecimal first, second, result ;
        first = new BigDecimal("33.33333333333333")  ;
        second = new BigDecimal("100") ;
        result = first.divide(second);
        System.out.println("result is " + result);
       //will print : result is 0.3333333333333333


    }
}

and to plug my new favorite language, Groovy, here is a neater example of the same thing:

import java.math.BigDecimal

def  first =   new BigDecimal("33.33333333333333")
def second = new BigDecimal("100")


println "result is " + first/second   // will print: result is 0.33333333333333

I know this is a really old post, but I found it in searching for a solution to the same problem. I don't want a nested if-statement, and Switch is apparently newer than the version of Excel I'm using. I figured out what was going wrong with my code, so I figured I'd share here in case it helps someone else.

I remembered that VLOOKUP requires the source table to be sorted alphabetically/numerically for it to work. I was initially trying to do this...

=LOOKUP(LOWER(LEFT($T$3, 1)),  {"s","l","m"}, {-1,1,0})

and it started working when I did this...

=LOOKUP(LOWER(LEFT($T$3, 1)),  {"l","m","s"}, {1,0,-1})

I was initially thinking the last value might turn out to be a default, so I wanted the zero at the last place. That doesn't seem to be the behavior anyway, so I just put the possible matches in order, and it worked.

Edit: As a final note, I see that the example in the original post has letters in alphabetical order, but I imagine the real use case might have been different if the error was happening and the letters A, B, and C were just examples.

For int use this:

>>> "1221323".isdigit()
True

But for float we need some tricks ;-). Every float number has one point...

>>> "12.34".isdigit()
False
>>> "12.34".replace('.','',1).isdigit()
True
>>> "12.3.4".replace('.','',1).isdigit()
False

Also for negative numbers just add lstrip():

>>> '-12'.lstrip('-')
'12'

And now we get a universal way:

>>> '-12.34'.lstrip('-').replace('.','',1).isdigit()
True
>>> '.-234'.lstrip('-').replace('.','',1).isdigit()
False

If you are OK to run Java command line then you can do it with Apache POI HSSF's Excel Extractor. It has a main method that says to be the command line extractor. This one seems to just dump everything out. They point out to this example that converts to CSV. You would have to compile it before you can run it but it too has a main method so you should not have to do much coding per se to make it work.

Another option that might fly but will require some work on the other end is to make your Excel files come to you as Excel XML Data or XML Spreadsheet of whatever MS calls that format these days. It will open a whole new world of opportunities for you to slice and dice it the way you want.

Thanks for the answers above. Here's how I did it, I hope it helps those who follow. I'm looking to pass a registration number from one page to another, hence regName and regValue:

Create your first page, call it set_reg.php:

<?php

session_start();

$_SESSION['regName'] = $regValue;

?>

<form method="get" action="get_reg.php">
    <input type="text" name="regName" value="">
    <input type="submit">
</form>

Create your second page, call it get_reg.php:

<?php

session_start();

$regValue = $_GET['regName'];

echo "Your registration is: ".$regValue.".";

?>

<p><a href="set_reg.php">Back to set_reg.php</a>

Although not as comprehensive as the answer above, for my purposes this illustrates in simple fashion the relationship between the various elements.

    final Calendar newCalendar = Calendar.getInstance();
    final DatePickerDialog  StartTime = new DatePickerDialog(this, new DatePickerDialog.OnDateSetListener() {
                public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
                    Calendar newDate = Calendar.getInstance();
                    newDate.set(year, monthOfYear, dayOfMonth);
                    activitydate.setText(dateFormatter.format(newDate.getTime()));
                }
    
            }, newCalendar.get(Calendar.YEAR), newCalendar.get(Calendar.MONTH), newCalendar.get(Calendar.DAY_OF_MONTH));
    
      btn_checkin.setOnClickListener(new View.OnClickListener() {
@Override   public void onClick(View v) {
         StartTime.show():    
     });

select * from table_name ORDER BY primary_id DESC FETCH FIRST 1 ROWS ONLY;

That's the simplest one without doing sub queries

You need to just replace ' with '' inside your string

SELECT colA, colB, colC
FROM tableD
WHERE colA = 'John''s Mobile'

You can also use REPLACE(@name, '''', '''''') if generating the SQL dynamically

If you want to escape inside a like statement then you need to use the ESCAPE syntax

It's also worth mentioning that you're leaving yourself open to SQL injection attacks if you don't consider it. More info at Google or: http://it.toolbox.com/wiki/index.php/How_do_I_escape_single_quotes_in_SQL_queries%3F

I wrote a function which solves the problem precisely.

First argument is the string that wanted to be parameterized. You should put your variables in this string like this format "%s1, %s2, ... %s12".

Other arguments are the parameters respectively for that string.

/***
 * @example parameterizedString("my name is %s1 and surname is %s2", "John", "Doe");
 * @return "my name is John and surname is Doe"
 *
 * @firstArgument {String} like "my name is %s1 and surname is %s2"
 * @otherArguments {String | Number}
 * @returns {String}
 */
const parameterizedString = (...args) => {
  const str = args[0];
  const params = args.filter((arg, index) => index !== 0);
  if (!str) return "";
  return str.replace(/%s[0-9]+/g, matchedStr => {
    const variableIndex = matchedStr.replace("%s", "") - 1;
    return params[variableIndex];
  });
}

Examples

parameterizedString("my name is %s1 and surname is %s2", "John", "Doe");
// returns "my name is John and surname is Doe"

parameterizedString("this%s1 %s2 %s3", " method", "sooo", "goood");
// returns "this method sooo goood"

If variable position changes in that string, this function supports it too without changing the function parameters.

parameterizedString("i have %s2 %s1 and %s4 %s3.", "books", 5, "pencils", "6");
// returns "i have 5 books and 6 pencils."

Use the onsubmit event to execute JavaScript code when the form is submitted. You can then return false or call the passed event's preventDefault method to disable the form submission.

For example:

<script>
function doSomething() {
    alert('Form submitted!');
    return false;
}
</script>

<form onsubmit="return doSomething();" class="my-form">
    <input type="submit" value="Submit">
</form>

This works, but it's best not to litter your HTML with JavaScript, just as you shouldn't write lots of inline CSS rules. Many Javascript frameworks facilitate this separation of concerns. In jQuery you bind an event using JavaScript code like so:

<script>
$('.my-form').on('submit', function () {
    alert('Form submitted!');
    return false;
});
</script>

<form class="my-form">
    <input type="submit" value="Submit">
</form>

In Python 3 the dict.values() method returns a dictionary view object, not a list like it does in Python 2. Dictionary views have a length, can be iterated, and support membership testing, but don't support indexing.

To make your code work in both versions, you could use either of these:

{names[i]:value for i,value in enumerate(d.values())}

    or

values = list(d.values())
{name:values[i] for i,name in enumerate(names)}

By far the simplest, fastest way to do the same thing in either version would be:

dict(zip(names, d.values()))

Note however, that all of these methods will give you results that will vary depending on the actual contents of d. To overcome that, you may be able use an OrderedDict instead, which remembers the order that keys were first inserted into it, so you can count on the order of what is returned by the values() method.

Just set the JDK path from the below steps:

1. Go to 'Run' ->External Tools -> External Tools Configuration

2. -> Select 'JRE' Then from the DropDown list select the available JDK . ex. jdk1.8.0_25

Are you aware of Mysql Spatial extensions?

You could use something like MBRContains(g1,g2).

I know this is an old post but as MisterZimbu stated, the color property is defining the values of other properties, as the border-color and, with CSS3, of currentColor.

currentColor is very handy if you want to use the font color for other elements (as the background or custom checkboxes and radios of inner elements for example).

Example:

.element {_x000D_
  color: green;_x000D_
  background: red;_x000D_
  display: block;_x000D_
  width: 200px;_x000D_
  height: 200px;_x000D_
  padding: 0;_x000D_
  margin: 0;_x000D_
}_x000D_
_x000D_
.innerElement1 {_x000D_
  border: solid 10px;_x000D_
  display: inline-block;_x000D_
  width: 60px;_x000D_
  height: 100px;_x000D_
  margin: 10px;_x000D_
}_x000D_
_x000D_
.innerElement2 {_x000D_
  background: currentColor;_x000D_
  display: inline-block;_x000D_
  width: 60px;_x000D_
  height: 100px;_x000D_
  margin: 10px;_x000D_
}

<div class="element">_x000D_
  <div class="innerElement1"></div>_x000D_
  <div class="innerElement2"></div>_x000D_
</div>

You may use rbind but in this case you need to have the same number of columns in both tables, so try the following:

b$b<-as.double(NA) #keeping numeric format is essential for further calculations
new<-rbind(a,b)

Using sqldf package:

library(sqldf)

sqldf("select a.*, b.cnt
       from df a,
           (select name, type, count(1) as cnt
            from df
            group by name, type) b
      where a.name = b.name and
            a.type = b.type")

#    name  type num cnt
# 1 black chair   4   2
# 2 black chair   5   2
# 3 black  sofa  12   1
# 4   red  sofa   4   1
# 5   red plate   3   1

Use max-width property of CSS, like this :

img{
  max-width:100%;
}

The most important use case is probably exception checking.

While junit4 includes the expected element for checking if an exception occurred, it seems like it isn't part of the newer junit5. Another advantage of using fail() over the expected is that you can combine it with finally allowing test-case cleanup.

dao.insert(obj);
try {
  dao.insert(obj);
  fail("No DuplicateKeyException thrown.");
} catch (DuplicateKeyException e) {
  assertEquals("Error code doesn't match", 123, e.getErrorCode());
} finally {
  //cleanup
  dao.delete(obj);
}

As noted in another comment. Having a test to fail until you can finish implementing it sounds reasonable as well.

There is one more thing you should be aware of - MIME.

If you need to use a MIME type and it isn't supported by default, you can register your own handlers in config/initializers/mime_types.rb:

Mime::Type.register "text/markdown", :markdown

You need to put it in the join clause, not the where:

SELECT *
FROM categories
LEFT JOIN user_category_subscriptions ON 
    user_category_subscriptions.category_id = categories.category_id
    and user_category_subscriptions.user_id =1

See, with an inner join, putting a clause in the join or the where is equivalent. However, with an outer join, they are vastly different.

As a join condition, you specify the rowset that you will be joining to the table. This means that it evaluates user_id = 1 first, and takes the subset of user_category_subscriptions with a user_id of 1 to join to all of the rows in categories. This will give you all of the rows in categories, while only the categories that this particular user has subscribed to will have any information in the user_category_subscriptions columns. Of course, all other categories will be populated with null in the user_category_subscriptions columns.

Conversely, a where clause does the join, and then reduces the rowset. So, this does all of the joins and then eliminates all rows where user_id doesn't equal 1. You're left with an inefficient way to get an inner join.

Hopefully this helps!

And here my version of finding N random unique numbers using HashSet. Looks pretty simple, since HashSet can contain only different items. It's interesting - would it be faster then using List or Shuffler?

using System;
using System.Collections.Generic;

namespace ConsoleApplication1
{
    class RnDHash
    {
        static void Main()
        {
            HashSet<int> rndIndexes = new HashSet<int>();
            Random rng = new Random();
            int maxNumber;
            Console.Write("Please input Max number: ");
            maxNumber = int.Parse(Console.ReadLine());
            int iter = 0;
            while (rndIndexes.Count != maxNumber)
            {
                int index = rng.Next(maxNumber);
                rndIndexes.Add(index);
                iter++;
            }
            Console.WriteLine("Random numbers were found in {0} iterations: ", iter);
            foreach (int num in rndIndexes)
            {
                Console.WriteLine(num);
            }
            Console.ReadKey();
        }
    }
}

The easiest way to add a text to a JFrame:

JFrame window = new JFrame("JFrame with text"); 
window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
window.setLayout(new BorderLayout());
window.add(new JLabel("Hello World"), BorderLayout.CENTER);
window.pack();
window.setVisible(true);
window.setLocationRelativeTo(null);

I was recently working with IPFS and worked this out. A curl example for IPFS to upload a file looks like this:

curl -i -H "Content-Type: multipart/form-data; boundary=CUSTOM" -d $'--CUSTOM\r\nContent-Type: multipart/octet-stream\r\nContent-Disposition: file; filename="test"\r\n\r\nHello World!\n--CUSTOM--' "http://localhost:5001/api/v0/add"

The basic idea is that each part (split by string in boundary with --) has it's own headers (Content-Type in the second part, for example.) The FormData object manages all this for you, so it's a better way to accomplish our goals.

This translates to fetch API like this:

const formData = new FormData()
formData.append('blob', new Blob(['Hello World!\n']), 'test')

fetch('http://localhost:5001/api/v0/add', {
  method: 'POST',
  body: formData
})
.then(r => r.json())
.then(data => {
  console.log(data)
})

I just happened to look for something similar and came up with this:

std::cout << std::setfill(' ') << std::setw(n) << ' ';

I tried all the solution mentioned above

in Manifest.xml :

• add this code in top of your xml file within manifest tag:

  xmlns:tools="http://schemas.android.com/tools"

• Then added :

  tools:replace="android:icon,android:theme,android:label,android:name" to the application tag

but none of it worked. I needed to delete a xml file which was situated in

mipmap-anydpi-v26/ic_launcher_round.xml

I was testing the application in

Samsung Galaxy 8 with OS version 8.0.0

is it really a solution?

Delete the most recent commit, keeping the work you've done:

git reset --soft HEAD~1

Delete the most recent commit, destroying the work you've done:

git reset --hard HEAD~1

Use this jQuery plugin https://gianlucaguarini.github.io/jQuery.BlackAndWhite/

That seems to be the only one cross-browser solution. Plus it has a nice fade in and fade out effect.

$('.bwWrapper').BlackAndWhite({
    hoverEffect : true, // default true
    // set the path to BnWWorker.js for a superfast implementation
    webworkerPath : false,
    // to invert the hover effect
    invertHoverEffect: false,
    // this option works only on the modern browsers ( on IE lower than 9 it remains always 1)
    intensity:1,
    speed: { //this property could also be just speed: value for both fadeIn and fadeOut
        fadeIn: 200, // 200ms for fadeIn animations
        fadeOut: 800 // 800ms for fadeOut animations
    },
    onImageReady:function(img) {
        // this callback gets executed anytime an image is converted
    }
});

I needed to set a default just as if it was specified as default column value in DB. So it behaves like this

a = Item.new
a.published_at # => my default value

a = Item.new(:published_at => nil)
a.published_at # => nil

Because after_initialize callback is called after setting attributes from arguments, there was no way to know if the attribute is nil because it was never set or because it was intentionally set as nil. So I had to poke inside a bit and came with this simple solution.

class Item < ActiveRecord::Base
  def self.column_defaults
    super.merge('published_at' => Time.now)
  end
end

Works great for me. (Rails 3.2.x)

Every time you are creating plots you might get this error - "Error in plot.new() : figure margins too large". To avoid such errors you can first check par("mar") output. You should be getting:

[1] 5.1 4.1 4.1 2.1

To change that write:

par(mar=c(1,1,1,1))

This should rectify the error. Or else you can change the values accordingly.

Hope this works for you.

Using Android Studio you have to add the dependency of the support library that was not indicated in the tutorial

dependencies {

    implementation 'com.android.support:appcompat-v7:22.0.0'
}

I had this problem in one legacy application that create prepared statement dynamically.

String firstName;
StringBuilder query =new StringBuilder("select id, name from employee where country_Code=1");
query.append("and  name like '");
query.append(firstName + "' ");
query.append("and ssn=?");
PreparedStatement preparedStatement =new prepareStatement(query.toString());

when it try to set value for ssn, it was giving invalid column index error, and finally found out that it is caused by firstName having ' within; that disturb the syntax.

The solution of creating a new HTML file with HTML (Web Forms) Designer worked for that file but not for other, individual HTML files that I wanted to edit.

I did find the Open With option in the Open File dialogue and was able to select the HTML (Web Forms) Editor there. Having clicked the "Set as Default" option in that window, VS then remembered to use that editor when I opened other HTML files.

If you use jquery:

$('head').append('<link rel="stylesheet" type="text/css" href="style.css">');

You can use function colSums() to calculate sum of all values. [,-1] ensures that first column with names of people is excluded.

 colSums(people[,-1])
Height Weight 
   199    425

Assuming there could be multiple columns that are not numeric, or that your column order is not fixed, a more general approach would be:

colSums(Filter(is.numeric, people))

Your example is perfect: the field is private and it has a getter. This is the normal way to access a field. If you need a direct access to an object field, use reflection. Using reflection to get a field's value is a hack and should be used in extreme cases such as using a library whose code you cannot change.

Request-scoped beans can be autowired with the request object.

private @Autowired HttpServletRequest request;

you can use jquery validator for that but you need to add jquery.validate.js and jquery.form.js file for that. after including validator file define your validation something like this.

<script type="text/javascript">
$(document).ready(function(){
    $("#formID").validate({
    rules :{
        "data[User][name]" : {
            required : true
        }
    },
    messages :{
        "data[User][name]" : {
            required : 'Enter username'
        }
    }
    });
});
</script>

You can see required : true same there is many more property like for email you can define email : true for number number : true

Adding the System.Configuration as reference to all the projects will solve this.

1. Go to Project -> Add Reference

2. In the box that appears, click the All assemblies list tab in the left hand list.

3. In the central list, scroll to System.Configuration and make sure the box is checked.

4. Click ok to apply, and you'll now be able to access the ConfigurationManager class.

There is an NPM module for this:

npm dree

It allows you to have a representation of a directory tree as a string or an object. Using it with the command line will allow you to save the representation in a txt file.

Example:

$ npm dree parse myDirectory --dest ./generated --name tree

Instead of doing all this create a LinkedHashSet object and random numbers to it by Math.random() function .... if any duplicated entry occurs the LinkedHashSet object won't add that number to its List ... Since in this Collection Class no duplicate values are allowed .. in the end u get a list of random numbers having no duplicated values .... :D

I created this simple example from different search results on the internet.

public static ServiceHost CreateServiceHost(Type serviceInterface, Type implementation)
{
  //Create base address
  string baseAddress = "net.pipe://localhost/MyService";

  ServiceHost serviceHost = new ServiceHost(implementation, new Uri(baseAddress));

  //Net named pipe
  NetNamedPipeBinding binding = new NetNamedPipeBinding { MaxReceivedMessageSize = 2147483647 };
  serviceHost.AddServiceEndpoint(serviceInterface, binding, baseAddress);

  //MEX - Meta data exchange
  ServiceMetadataBehavior behavior = new ServiceMetadataBehavior();
  serviceHost.Description.Behaviors.Add(behavior);
  serviceHost.AddServiceEndpoint(typeof(IMetadataExchange), MetadataExchangeBindings.CreateMexNamedPipeBinding(), baseAddress + "/mex/");

  return serviceHost;
}

Using the above URI I can add a reference in my client to the web service.

Depending on your needs, TABLESAMPLE will get you nearly as random and better performance. this is available on MS SQL server 2005 and later.

TABLESAMPLE will return data from random pages instead of random rows and therefore deos not even retrieve data that it will not return.

On a very large table I tested

select top 1 percent * from [tablename] order by newid()

took more than 20 minutes.

select * from [tablename] tablesample(1 percent)

took 2 minutes.

Performance will also improve on smaller samples in TABLESAMPLE whereas it will not with newid().

Please keep in mind that this is not as random as the newid() method but will give you a decent sampling.

See the MSDN page.

did you try this ?

$("#yourdiv").load(url, function(){ 

         your functions goes here !!!

}); 

It is just simple.

Use this pattern: \b((ftp|https?)://)?([\w-\.]+\.(com|net|org|gov|mil|int|edu|info|me)|(\d+\.\d+\.\d+\.\d+))(:\d+)?(\/[\w-\/]*(\?\w*(=\w+)*[&\w-=]*)*(#[\w-]+)*)?

It matches any link contains:

Allowed Protocols: http, https and ftp

Allowed Domains: *.com, *.net, *.org, *.gov, *.mil, *.int, *.edu, *.info and *.me OR IP

Allowed Ports: true

Allowed Parameters: true

Allowed Hashes: true

We could use tidyr::extract()

x <- c("F.US.CLE.V13", "F.US.CA6.U13", "F.US.CA6.U13", "F.US.CA6.U13", 
  "F.US.CA6.U13", "F.US.CA6.U13", "F.US.CA6.U13", "F.US.CA6.U13", 
  "F.US.DL.U13", "F.US.DL.U13", "F.US.DL.U13", "F.US.DL.Z13", "F.US.DL.Z13"
)


library(tidyr)
extract(tibble(data=x),"data", regex = "^(.*?)\\.(.*?)\\.(.*?)\\.(.*?)$",into = LETTERS[1:4])
#> # A tibble: 13 x 4
#>    A     B     C     D

Another option is to use unglue::unglue_data()

# remotes::install_github("moodymudskipper/unglue")
library(unglue)
unglue_data(x,"{A}.{B}.{C}.{D}")
#>    A  B   C   D

I had the same problem.

I use project level connection managers and my packages run correctly in SSDT but when I deployed them and execute them through a job with sql server agent, I get "Connection not found" errors.

So I deploy the project and then the problem was solved, when you use project level connection managers but just deploy a single package from that project, and you call package through sql server agent, it could not recognize your connection managers so you should determine package level connection managers or you should first deploy your project.

If you are entering your credentials into the Visual Studio popup you might see an error that says "Login was not successful". However, this might not be true. Studio will open a browser window saying that it was in fact successful. There is then a dance between the browser and Studio where you need to accept / allow the authentication at certain points.

With RxJS 5.5+, the catch operator is now deprecated. You should now use the catchError operator in conjunction with pipe.

RxJS v5.5.2 is the default dependency version for Angular 5.

For each RxJS Operator you import, including catchError you should now import from 'rxjs/operators' and use the pipe operator.

Example of catching error for an Http request Observable

import { Observable } from 'rxjs';
import { catchError } from 'rxjs/operators';
...

export class ExampleClass {
  constructor(private http: HttpClient) {
    this.http.request(method, url, options).pipe(
      catchError((err: HttpErrorResponse) => {
        ...
      }
    )
  }
  ...
}

Notice here that catch is replaced with catchError and the pipe operator is used to compose the operators in similar manner to what you're used to with dot-chaining.

See the rxjs documentation on pipable (previously known as lettable) operators for more info.

Something like:

var rnd = new Random(DateTime.Now.Millisecond);
int ticks = rnd.Next(0, 3000);

Remove the function and check the output of:

var_dump(function_exists('parseDate'));

In which case, change the name of the function.

If you get false, you're including the file with that function twice, replace :

include

by

include_once

And replace :

require

by

require_once

EDIT : I'm just a little too late, post before beat me to it !

Okay... Finally I could install it! Why? or what I did? well I am not sure. first I downloaded and installed the package (I installed all the files(3) from the disk image) but I couldn't start it. (nor from the preferences panel, nor from the termial)

second I removed it and installed through mac ports.

again, the same thing. could not start it.

Now I deleted it again, installed from the package. (i am not sure if it was the exact same package but I think it is) Only this time I got the package from another site(its a mirror).

the site:

http://www.mmisoftware.co.uk/weblog/2009/08/29/mac-os-x-10-6-snow-leopard-and-mysql/

and the link:

http://mirror.services.wisc.edu/mysql/Downloads/MySQL-5.1/mysql-5.1.37-osx10.5-x86.dmg

1.- install mysql-5-1.37-osx10.5-x86.pkg

2.- install MySQLStartupItem.pkg

3.- install MySQL.prefpanel

And this time is working fine (even the preferences panel!)

Nothing special, I don't know what happened the first two times.

But thank you all. Regards.

restrict is for defining the directive type, and it can be A (Attribute), C (Class), E (Element), and M (coMment) , let's assume that the name of the directive is Doc :

Type : Usage

A = <div Doc></div>

C = <div class="Doc"></div>

E = <Doc data="book_data"></Doc>

M = <!--directive:Doc -->

Constructor Injection fails when there is Circular Dependency between spring beans. So in this case we Setter injection helps to resolve the issue.

Basically, Constructor Injection is useful for Mandatory dependencies, for optional dependencies better to use Setter injection because we can do re-injection.

You can use .is().

if( $('#leftmenu').is(':empty') ) {
    // ...

Or you could just test the length property to see if one was found.

if( $('#leftmenu:empty').length ) {
    // ...

Keep in mind that empty means no white space either. If there's a chance that there will be white space, then you can use $.trim() and check for the length of the content.

if( !$.trim( $('#leftmenu').html() ).length ) {
    // ...

The simple way to do that in Angular 7+ is to:

Define a path in your ?-routing.module.ts

{ path: '/yourpage', component: component-name }

Import the ActivateRoute and Router module in your component and inject them in the constructor

contructor(private route: ActivateRoute, private router: Router){ ... }

Subscribe the ActivateRoute to the ngOnInit

ngOnInit() {

    this.route.queryParams.subscribe(params => {
      console.log(params);
      // {page: '2' }
    })
}

Provide it to a link:

<a [routerLink]="['/yourpage']" [queryParams]="{ page: 2 }">2</a>

Since c++11 we could use list initialization:

char* c = new char[length]{};

For an aggregate type, then aggregate initialization will be performed, which has the same effect like char c[2] = {};.

I was doing some testing and got this:

class A {
  public $property;
}

function set_property($obj) {
  $obj->property = "after";
  var_dump($obj);
}

$a = new A();
$a->property = "before";

// Creates a new Object from $a. Like "new A();"
$b = new $a;
// Makes a Copy of var $a, not referenced.
$c = clone $a;

set_property($a);
// object(A)#1 (1) { ["property"]=> string(5) "after" }

var_dump($a); // Because function set_property get by reference
// object(A)#1 (1) { ["property"]=> string(5) "after" }
var_dump($b);
// object(A)#2 (1) { ["property"]=> NULL }
var_dump($c);
// object(A)#3 (1) { ["property"]=> string(6) "before" }

// Now creates a new obj A and passes to the function by clone (will copied)
$d = new A();
$d->property = "before";

set_property(clone $d); // A new variable was created from $d, and not made a reference
// object(A)#5 (1) { ["property"]=> string(5) "after" }

var_dump($d);
// object(A)#4 (1) { ["property"]=> string(6) "before" }

?>

In order to connect remotely you have to have MySQL bind port 3306 to your machine's IP address in my.cnf. Then you have to have created the user in both localhost and '%' wildcard and grant permissions on all DB's as such . See below:

my.cnf (my.ini on windows)

#Replace xxx with your IP Address 
bind-address        = xxx.xxx.xxx.xxx

then

CREATE USER 'myuser'@'localhost' IDENTIFIED BY 'mypass';
CREATE USER 'myuser'@'%' IDENTIFIED BY 'mypass';

Then

GRANT ALL ON *.* TO 'myuser'@'localhost';
GRANT ALL ON *.* TO 'myuser'@'%';
flush privileges;

Depending on your OS you may have to open port 3306 to allow remote connections.

A note to this:

IE 8.0s emulation only promises to display the page the same. There are subtle differences that might cause functionality to break. I recently had a problem with just that. Where IE 7.0 uses a javascript wrapper-function called "anonymous()" in IE 8.0 the wrapper was named differently.

So do not expect things like JavaScript to "just work", because you turn on emulation.

If your input is a child element of the label and you have more than one labels, you can combine @Mike's trick with Flexbox + order.

label.switchLabel {

See it on JSFiddle.

note: Sibling selector only works within the same parent. To work around this, you can make the input hidden at top-level using @Nathan Blair hack.

This may be achieved by using AppCompatCheckBox. You can use app:buttonCompat="@drawable/selector_drawable" to change the selector.

It's working with PNGs, but I didn't find a way for it to work with Vector Drawables.

showing form input element fields and input file to submit your form without page refresh and grab all values with file include in it here it is

Use data option of ajax. You can send data object to server by data option in ajax and the type which defines how you are sending it (either POST or GET). The default type is GET method

Try this

$.ajax({
  url: "ajax.aspx",
  type: "get", //send it through get method
  data: { 
    ajaxid: 4, 
    UserID: UserID, 
    EmailAddress: EmailAddress
  },
  success: function(response) {
    //Do Something
  },
  error: function(xhr) {
    //Do Something to handle error
  }
});

And you can get the data by (if you are using PHP)

 $_GET['ajaxid'] //gives 4
 $_GET['UserID'] //gives you the sent userid

In aspx, I believe it is (might be wrong)

 Request.QueryString["ajaxid"].ToString(); 

If you are using Notepad++ editor Goto ctrl + F choose tab 3 find in files and enter:

1. Find What = text1*.*text2
2. Filters : .
3. Search mode = Regular Expression
4. Directory = enter the path of the directory you want to search in. You can check Follow current doc. to have the path of the current file to be filled.

I think you should use python wheels for distribution instead of egg now.

Wheels are the new standard of python distribution and are intended to replace eggs. Support is offered in pip >= 1.4 and setuptools >= 0.8.

Do you want to return a full row? Does the default row need to have default values or can it be an empty row? Do you want the default row to have the same column structure as the table in question?

Depending on your requirements, you might do something like this:

1) run the query and put results in a temp table (or table variable) 2) check to see if the temp table has results 3) if not, return an empty row by performing a select statement similar to this (in SQL Server):

select '' as columnA, '' as columnB, '' as columnC from #tempTable

Where columnA, columnB and columnC are your actual column names.

This gives me the same error as trying to split the list up and zip it. ValueError: dictionary update sequence element #0 has length 1916; 2 is required

THAT is your actual question.

The answer is that the elements of your list are not what you think they are. If you type myList[0] you will find that the first element of your list is not a two-tuple, e.g. ('A', 1), but rather a 1916-length iterable.

Once you actually have a list in the form you stated in your original question (myList = [('A',1),('B',2),...]), all you need to do is dict(myList).

it can be done by using this command: tcptraceroute -p destination port destination IP. like: tcptraceroute -p 9100 10.0.0.50 but don't forget to install tcptraceroute package on your system. tcpdump and nc by default installed on the system. regards

It looks like most of post here described what you need here. However - something you might need more complex behavior - depending on what you're parsing. In your case it might be so that you won't need more complex parsing - but it depends what information you're extracting.

You can use regex groups as field name in class, after which could be written for example like this:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Reflection;
using System.Text.RegularExpressions;

public class Info
{
    public String Identifier;
    public char nextChar;
};

class testRegex {

    const string input = "Lorem ipsum dolor sit %download%#456 amet, consectetur adipiscing %download%#3434 elit. " +
    "Duis non nunc nec mauris feugiat porttitor. Sed tincidunt blandit dui a viverra%download%#298. Aenean dapibus nisl %download%#893434 id nibh auctor vel tempor velit blandit.";

    static void Main(string[] args)
    {
        Regex regex = new Regex(@"%download%#(?<Identifier>[0-9]*)(?<nextChar>.)(?<thisCharIsNotNeeded>.)");
        List<Info> infos = new List<Info>();

        foreach (Match match in regex.Matches(input))
        {
            Info info = new Info();
            for( int i = 1; i < regex.GetGroupNames().Length; i++ )
            {
                String groupName = regex.GetGroupNames()[i];

                FieldInfo fi = info.GetType().GetField(regex.GetGroupNames()[i]);

                if( fi != null ) // Field is non-public or does not exists.
                    fi.SetValue( info, Convert.ChangeType( match.Groups[groupName].Value, fi.FieldType));
            }
            infos.Add(info);
        }

        foreach ( var info in infos )
        {
            Console.WriteLine(info.Identifier + " followed by '" + info.nextChar.ToString() + "'");
        }
    }

};

This mechanism uses C# reflection to set value to class. group name is matched against field name in class instance. Please note that Convert.ChangeType won't accept any kind of garbage.

If you want to add tracking of line / column - you can add extra Regex split for lines, but in order to keep for loop intact - all match patterns must have named groups. (Otherwise column index will be calculated incorrectly)

This will results in following output:

456 followed by ' '
3434 followed by ' '
298 followed by '.'
893434 followed by ' '

Zipalign gradle task is deprecated since Android Plugin for Gradle, Revision 2.2.0 (September 2016).

If you want to keep using it, add android.useOldPackaging=true to your gradle.properties file.

Click here for detailed explanation.

Improves build performance by adopting a new default packaging pipeline which handles zipping, signing, and zipaligning in one task. You can revert to using the older packaging tools by adding android.useOldPackaging=true to your gradle.properties file. While using the new packaging tool, the zipalignDebug task is not available. However, you can create one yourself by calling the createZipAlignTask(String taskName, File inputFile, File outputFile) method. APK signing now uses APK Signature Scheme v2 in addition to traditional JAR signing. All Android platforms accept the resulting APKs. Any modification to these APKs after signing invalidates their v2 signatures and prevents installation on a device. Blockquote

You can also set up a mime type for application/JavaScript to run as PHP, .NET, Java, or whatever language you're using. I've done this for dynamic CSS files in the past.

As of Python 3.2+, you can also accomplish this using the from_bytes native int method:

file_size = int.from_bytes(fin.read(2), byteorder='big')

Note that this function requires you to specify whether the number is encoded in big- or little-endian format, so you will have to determine the endian-ness to make sure it works correctly.

Use the in keyword.

if 'apples' in d:
    if d['apples'] == 20:
        print('20 apples')
    else:
        print('Not 20 apples')

If you want to get the value only if the key exists (and avoid an exception trying to get it if it doesn't), then you can use the get function from a dictionary, passing an optional default value as the second argument (if you don't pass it it returns None instead):

if d.get('apples', 0) == 20:
    print('20 apples.')
else:
    print('Not 20 apples.')

Just use

 as.Date("2001-01-01") + 45

from base R, or date functionality in one of the many contributed packages. My RcppBDT package wraps functionality from Boost Date_Time including things like 'date of third Wednesday' in a given month.

Edit: And egged on by @Andrie, here is a bit more from RcppBDT (which is mostly a test case for Rcpp modules, really).

I just tested this and it works in Access 2010.

Say you have a SELECT query with parameters:

PARAMETERS startID Long, endID Long;
SELECT Members.*
FROM Members
WHERE (((Members.memberID) Between [startID] And [endID]));

You run that query interactively and it prompts you for [startID] and [endID]. That works, so you save that query as [MemberSubset].

Now you create an UPDATE query based on that query:

UPDATE Members SET Members.age = [age]+1
WHERE (((Members.memberID) In (SELECT memberID FROM [MemberSubset])));

You run that query interactively and again you are prompted for [startID] and [endID] and it works well, so you save it as [MemberSubsetUpdate].

You can run [MemberSubsetUpdate] from VBA code by specifying [startID] and [endID] values as parameters to [MemberSubsetUpdate], even though they are actually parameters of [MemberSubset]. Those parameter values "trickle down" to where they are needed, and the query does work without human intervention:

Sub paramTest()
    Dim qdf As DAO.QueryDef
    Set qdf = CurrentDb.QueryDefs("MemberSubsetUpdate")
    qdf!startID = 1  ' specify
    qdf!endID = 2    '     parameters
    qdf.Execute
    Set qdf = Nothing
End Sub

The shared pointer manages both the object itself, and a small object containing the reference count and other housekeeping data. make_shared can allocate a single block of memory to hold both of these; constructing a shared pointer from a pointer to an already-allocated object will need to allocate a second block to store the reference count.

As well as this efficiency, using make_shared means that you don't need to deal with new and raw pointers at all, giving better exception safety - there is no possibility of throwing an exception after allocating the object but before assigning it to the smart pointer.

select cast (as time(0))

would be a good clause. For example:

(select cast(start_date as time(0))) AS 'START TIME'

I just the changed the langversion to default and it worked for me. VS 2015

Here is my solution:

If you got more than one library version, this may help.

1. set a breakpoint on the lib source code
2. let the code run to the breakpoint
3. you will got these tips

4. click the arrow icon

5. you will get this

   

6. double click to select the correct lib (normally the highest version of the lib is correct)

I have clicked the "disable" button by mistake, you can enable it in the debugger setting

If you do not have the tips in the step 3, maybe you can check whether you have checked the setting options

To overcome the issue of Win7 32bit VB6, try copying from Windows Server 2003 C:\Windows\system32\ the files mscomctl.ocx and mscomcctl.oba.

Try:

import numpy as np
dist = np.array([1,2,3,4,5])
r = 2
dr = 3
np.where(np.logical_and(dist> r, dist<=r+dr))

Output: (array([2, 3]),)

You can see Logic functions for more details.

Thank you all for your help.

This is what I have used in the end:

SELECT *, 
  CASE WHEN [url] NOT LIKE '%[^-A-Za-z0-9/.+$]%'

    ELSE 'No valid' 
  END [Validate]
FROM 
  *table*
  ORDER BY [Validate]

Starting from Python 3.4 there's pathlib built-in library. So the code could be something like:

from pathlib import Path

filename = "mysequence.fasta"
new_filename = Path(filename).stem + ".aln"

https://docs.python.org/3.4/library/pathlib.html#pathlib.PurePath.stem

I love pathlib :)

As others have noted, most likely you don't have .html set up to handle php code.

Having said that, if all you're doing is using index.html to include index.php, your question should probably be 'how do I use index.php as index document?

In which case, for Apache (httpd.conf), search for DirectoryIndex and replace the line with this (will only work if you have dir_module enabled, but that's default on most installs):

DirectoryIndex index.php

If you use other directory indexes, list them in order of preference i.e.

DirectoryIndex index.php index.phtml index.html index.htm

You can add eventListner to the form, that preventDefault() and convert form data to JSON as below:

const formToJSON = elements => [].reduce.call(elements, (data, element) => {_x000D_
  data[element.name] = element.value;_x000D_
  return data;_x000D_
_x000D_
}, {});_x000D_
_x000D_
const handleFormSubmit = event => {_x000D_
    event.preventDefault();_x000D_
    const data = formToJSON(form.elements);_x000D_
    console.log(data);_x000D_
  //  const odata = JSON.stringify(data, null, "  ");_x000D_
  const jdata = JSON.stringify(data);_x000D_
    console.log(jdata);_x000D_
_x000D_
    (async () => {_x000D_

And u can also use that select statement as left join query... Example :

... left join (select OrderNO,
   PartCode,
   Quantity from (select OrderNO,
         PartCode,
         Quantity,
         row_number() over(partition by OrderNO order by DateEntered desc) as rn
  from YourTable) as T where rn = 1 ) RESULT on ....

Hope this help someone that search for this :)

From the documentation:

Dynamic web applications also need static files. That’s usually where the CSS and JavaScript files are coming from. Ideally your web server is configured to serve them for you, but during development Flask can do that as well. Just create a folder called static in your package or next to your module and it will be available at /static on the application.

To generate URLs for static files, use the special 'static' endpoint name:

url_for('static', filename='style.css')

The file has to be stored on the filesystem as static/style.css.

Since this question is from 4 years ago new things have been implemented and among them there is a new function plt.subplots which is very convenient:

fig, axes = plot.subplots(nrows=2, ncols=3, sharex=True, sharey=True)

where axes is a numpy.ndarray of AxesSubplot objects, making it very convenient to go through the different subplots just using array indices [i,j].

//My Form
<form id="someform">
        <div class="input-group">
            <textarea placeholder="Post your Comment Here ..." name="post" class="form-control custom-control" rows="3" style="resize:none"></textarea> 
            <span class="input-group-addon">                                            
                <button type="submit" name="post_comment" class="btn btn-primary">
                    Post
                </button>
            </span>
        </div>
    </form>

//your text area get value to URL
<?php
        if(isset($_POST['post_comment']))
        {
            echo htmlspecialchars($_POST['post']);
        }

    ?>

//print the value using get
echo $_GET['post'];

//url must be like this
http://localhost/blog/home.php?post=asdasdsad&post_comment=

//post value has asdasdsad so it will print to your page

If you need to remove the HTML but does not know if it actually contains any HTML tags, you can't use the jQuery method directly because it returns empty wrapper for non-HTML text.

$('<div>Hello world</div>').text(); //returns "Hello world"
$('Hello world').text(); //returns empty string ""

You must either wrap the text in valid HTML:

$('<div>' + 'Hello world' + '</div>').text();

Or use method $.parseHTML() (since jQuery 1.8) that can handle both HTML and non-HTML text:

var html = $.parseHTML('Hello world'); //parseHTML return HTMLCollection
var text = $(html).text(); //use $() to get .text() method

Plus parseHTML removes script tags completely which is useful as anti-hacking protection for user inputs.

$('<p>Hello world</p><script>console.log(document.cookie)</script>').text();
//returns "Hello worldconsole.log(document.cookie)"

$($.parseHTML('<p>Hello world</p><script>console.log(document.cookie)</script>')).text();
//returns "Hello world"

This works for me:

$selectedindex=4

If you want to randomise options, you could always do something like this:

$0selectedindex=Math.floor((Math.random()*($0.length-1)+1)

Whilst 2nd bullet lies outside scope of your questions, it serves to illustrate how 1st bullet could be applied / amended as req.

Here is what worked for me:

protected override System.Net.WebRequest GetWebRequest(Uri uri)
{
        HttpWebRequest request;
        request = (HttpWebRequest)base.GetWebRequest(uri);
        NetworkCredential networkCredentials =
        Credentials.GetCredential(uri, "Basic");
        if (networkCredentials != null)
        {
            byte[] credentialBuffer = new UTF8Encoding().GetBytes(
            networkCredentials.UserName + ":" +
            networkCredentials.Password);
            request.Headers["Authorization"] =
            "Basic " + Convert.ToBase64String(credentialBuffer);
            request.Headers["Cookie"] = "BCSI-CS-2rtyueru7546356=1";
            request.Headers["Cookie2"] = "$Version=1";
        }
        else
        {
            throw new ApplicationException("No network credentials");
        }
        return request;
}

Don't forget to set this property:

service.Credentials = new NetworkCredential("username", "password");  

Cookie and Cookie2 are set in header because java service was not accepting the request and I was getting Unauthorized error.

Nothing much new to add, but I have had a lot of real-world experience in GIS and geocoding from a previous job. Here is what I remember:

If it is a "every once in a while" need in your application, I would definitely recommend the Google or Yahoo Geocoding APIs, but be careful to read their licensing terms.

I know that the Google Maps API in general is easy to license for even commercial web pages, but can't be used in a pay-to-access situation. In other words you can use it to advertise or provide a service that drives ad revenue, but you can't charge people to acess your site or even put it behind a password system.

Despite these restrictions, they are both excellent choices because they frequently update their street databases. Most of the free backend tools and libraries use Census and TIGER road data that is updated infrequently, so you are less likely to successfully geocode addresses in rapidly growing areas or new subdivisions.

Most of the services also restrict the number of geocoding queries you can make per day, so it's OK to look up addresses of, say, new customers who get added to your database, but if you run a batch job that feeds thousands of addresses from your database into the geocoder, you're going to get shutoff.

I don't think this one has been mentioned yet, but ESRI has ArcWeb web services that include geocoding, although they aren't very cheap. Last time I used them it cost around 1.5cents per lookup, but you had to prepay a certain amount to get started. Again the major advantage is that the road data they use is kept up to date in a timely manner and you can use the data in commercial situations that Google doesn't allow. The ArcWeb service will also serve up high-resolution satellite and aerial photos a la Google Maps, again priced per request.

If you want to roll your own or have access to much more accurate data, you can purchase subscriptions to GIS data from companies like TeleAtlas, but that ain't cheap. You can buy only a state or county worth of data if your needs are extremely local. There are several tiers of data - GIS features only, GIS plus detailed streets, all that plus geocode data, all of that plus traffic flow/direction/speed limits for routing. Of course, the price goes up as you go up the tiers.

Finally, the Wikipedia article on Geocoding has some good information on the algorithms and techniques. Even if you aren't doing it in your own code, it's useful to know what kind of errors and accuracy you can expect from various kinds of data sources.

This happened to me after a java update, few things to check if you are sure your path has been set before:

1. if the path doesn't match the latest java install folder, change it (if your in eclipse check the eclipse.ini too to make sure your using your systems default vm (ie no VM tag) )

2. go to the java directory, there should be a 'jdk' and a 'jre' in the path, for example:

   C:\Program Files (x86)\Java\jdk1.8.0_72\jre
   

   if not you probably installed the JRE only not the JDK that

3. finally if the lib folder of the jdk (not jre) doesnt contain tools.jar then you have a problem with the install

You have a lot of variants for using @RequestParam with additional optional elements, e.g.

@RequestParam(required = false, defaultValue = "someValue", value="someAttr") String someAttr

If you don't put required = false - param will be required by default.

defaultValue = "someValue" - the default value to use as a fallback when the request parameter is not provided or has an empty value.

If request and method param are the same - you don't need value = "someAttr"

Semantically, you're probably looking for the one-liner

new Date().toLocaleString()

which formats the date in the locale of the user.

If you're really looking for a specific way to format dates, I recommend the moment.js library.

There are certain scenarios in which you can follow the steps suggested in the other answers, verify that Execution Policy is set correctly, and still have your scripts fail. If this happens to you, you are probably on a 64-bit machine with both 32-bit and 64-bit versions of PowerShell, and the failure is happening on the version that doesn't have Execution Policy set. The setting does not apply to both versions, so you have to explicitly set it twice.

Look in your Windows directory for System32 and SysWOW64.

Repeat these steps for each directory:

1. Navigate to WindowsPowerShell\v1.0 and launch powershell.exe

2. Check the current setting for ExecutionPolicy:

   Get-ExecutionPolicy -List

3. Set the ExecutionPolicy for the level and scope you want, for example:

   Set-ExecutionPolicy -Scope LocalMachine Unrestricted

Note that you may need to run PowerShell as administrator depending on the scope you are trying to set the policy for.

You can read a lot more here: Running Windows PowerShell Scripts

You can simply write:

val mutableList = mutableListOf<Kolory>()

This is the most idiomatic way.

Alternative ways are

val mutableList : MutableList<Kolory> = arrayListOf()

or

val mutableList : MutableList<Kolory> = ArrayList()

This is exploiting the fact that java types like ArrayList are implicitly implementing the type MutableList via a compiler trick.

this is how you can parse iCal files with javascript

    function calParse(str) {

        function parse() {
            var obj = {};
            while(str.length) {
                var p = str.shift().split(":");
                var k = p.shift(), p = p.join();
                switch(k) {
                    case "BEGIN":
                        obj[p] = parse();
                        break;
                    case "END":
                        return obj;
                    default:
                        obj[k] = p;
                }
            }
            return obj;
        }
        str = str.replace(/\n /g, " ").split("\n");
        return parse().VCALENDAR;
    }

    example = 
    'BEGIN:VCALENDAR\n'+
    'VERSION:2.0\n'+
    'PRODID:-//hacksw/handcal//NONSGML v1.0//EN\n'+
    'BEGIN:VEVENT\n'+
    'DTSTART:19970714T170000Z\n'+
    'DTEND:19970715T035959Z\n'+
    'SUMMARY:Bastille Day Party\n'+
    'END:VEVENT\n'+
    'END:VCALENDAR\n'


    cal = calParse(example);
    alert(cal.VEVENT.SUMMARY);

From the docs:

str.split([sep[, maxsplit]])

Return a list of the words in the string, using sep as the delimiter string. If maxsplit is given, at most maxsplit splits are done (thus, the list will have at most maxsplit+1 elements).

s.split('mango', 1)[1]

If you want to merge changes in SubBranch to MainBranch

1. you should be on MainBranch git checkout MainBranch
2. then run merge command git merge SubBranch

@Michiel is correct to create a button but the code for ActionScript 3 it is a little different - where movieClipName is the name of your 'button'.

movieClipName.addEventListener(MouseEvent.CLICK, callLink);
function callLink:void {
  var url:String = "http://site";
  var request:URLRequest = new URLRequest(url);
  try {
    navigateToURL(request, '_blank');
  } catch (e:Error) {
    trace("Error occurred!");
  }
}

Shorter version for those who like short code:

// usage: deleteOldFiles("./xml", "xml,xsl", 24 * 3600)


function deleteOldFiles($dir, $patterns = "*", int $timeout = 3600) {

    // $dir is directory, $patterns is file types e.g. "txt,xls", $timeout is max age

    foreach (glob($dir."/*"."{{$patterns}}",GLOB_BRACE) as $f) { 

        if (is_writable($f) && filemtime($f) < (time() - $timeout))
            unlink($f);

    }

}

This should work:

reload(my.module)

From the Python docs

Reload a previously imported module. The argument must be a module object, so it must have been successfully imported before. This is useful if you have edited the module source file using an external editor and want to try out the new version without leaving the Python interpreter.

If running Python 3.4 and up, do import importlib, then do importlib.reload(nameOfModule).

Don't forget the caveats of using this method:

• When a module is reloaded, its dictionary (containing the module’s global variables) is retained. Redefinitions of names will override the old definitions, so this is generally not a problem, but if the new version of a module does not define a name that was defined by the old version, the old definition is not removed.

• If a module imports objects from another module using from ... import ..., calling reload() for the other module does not redefine the objects imported from it — one way around this is to re-execute the from statement, another is to use import and qualified names (module.*name*) instead.

• If a module instantiates instances of a class, reloading the module that defines the class does not affect the method definitions of the instances — they continue to use the old class definition. The same is true for derived classes.

Not saying this is better, just another way:

$("#elem")[0].style.fontSize="20px";

This is not mentioned in you post but I suspect you are initiating an SSL connection from the browser to Apache, where VirtualHosts are configured, and Apache does a revese proxy to your Tomcat.

There is a serious bug in (some versions ?) of IE that sends the 'wrong' host information in an SSL connection (see EDIT below) and confuses the Apache VirtualHosts. In short the server name presented is the one of the reverse DNS resolution of the IP, not the one in the URL.

The workaround is to have one IP address per SSL virtual hosts/server name. Is short, you must end up with something like

1 server name == 1 IP address == 1 certificate == 1 Apache Virtual Host

EDIT

Though the conclusion is correct, the identification of the problem is better described here http://en.wikipedia.org/wiki/Server_Name_Indication

enter the below command to verify if zookeeper is running :

Hope this help!

Here is how I got without '[' and ']' in C#:

        var text = "This is a test string [more or less]";
        //Getting only string between '[' and ']'
        Regex regex = new Regex(@"\[(.+?)\]");
        var matchGroups = regex.Matches(text);
        for (int i = 0; i < matchGroups.Count; i++)
        {
            Console.WriteLine(matchGroups[i].Groups[1]);
        }

The output is:

more or less

We can add "AwaitTerminationSeconds" property for both taskExecutor and taskScheduler as below,

<property name="awaitTerminationSeconds" value="${taskExecutor .awaitTerminationSeconds}" />

<property name="awaitTerminationSeconds" value="${taskScheduler .awaitTerminationSeconds}" />

Documentation for "waitForTasksToCompleteOnShutdown" property says, when shutdown is called

"Spring's container shutdown continues while ongoing tasks are being completed. If you want this executor to block and wait for the termination of tasks before the rest of the container continues to shut down - e.g. in order to keep up other resources that your tasks may need -, set the "awaitTerminationSeconds" property instead of or in addition to this property."

https://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/scheduling/concurrent/ExecutorConfigurationSupport.html#setWaitForTasksToCompleteOnShutdown-boolean-

So it is always advised to use waitForTasksToCompleteOnShutdown and awaitTerminationSeconds properties together. Value of awaitTerminationSeconds depends on our application.

whenever there are prerequisites to a usecase then,go for include.

for usecases having authentication,worst case scenario,or are optional then go for extend..

example:for a use case of seeking admission,appointment,ticket reservation YOU MUST FILL A form (registration or feedback form)....this is where include comes..

example:for a use case verifying login or sign in your account,your authentication is a must.also think of worst case scenarios.like returning book with fine..NOT getting a reservation..paying the bill AFTER DUE DATE..this is where extend comes to play...

do not overuse include and extend in the diagrams.

KEEP IT SIMPLE SILLY!!!

Here is a simple way using the date function:

select *
from hockey_stats
where date(game_date) between date('2012-11-03') and date('2012-11-05')
order by game_date desc

In a translation unit within the same namespace, usually at the top:

// foo.h
struct foo
{
    static const std::string s;
};

// foo.cpp
const std::string foo::s = "thingadongdong"; // this is where it lives

// bar.h
namespace baz
{
    struct bar
    {
        static const float f;
    };
}

// bar.cpp
namespace baz
{
    const float bar::f = 3.1415926535;
}

Here's an example using http://www.geoplugin.net/json.gp

$ip = $_SERVER['REMOTE_ADDR'];
$details = json_decode(file_get_contents("http://www.geoplugin.net/json.gp?ip={$ip}"));
echo $details;

Try this,

x in mylist is better and more readable than x in mylist[:] and your len(x) should be equal to 3.

>>> mylist = [[1,2,3],[4,5,6,7],[8,9,10]]
>>> for x in mylist:
...      if len(x)==3:
...        print x
...
[1, 2, 3]
[8, 9, 10]

or if you need more pythonic use list-comprehensions

>>> [x for x in mylist if len(x)==3]
[[1, 2, 3], [8, 9, 10]]
>>>

To get the length of a string stored in a variable, say:

myvar="some string"
size=${#myvar} 

To confirm it was properly saved, echo it:

$ echo "$size"
11

There's a class of question on SO that sometimes make less than perfect sense, this one is perilously close :-)

Perhaps you could explain your aversion to using one of the two methods you ruled out.

If it's just because you don't want to pepper your code with if statements or exception catching code, one solution is to use a helper function that will take care of it for you, something like:

static String substring_safe (String s, int start, int len) { ... }

which will check lengths beforehand and act accordingly (either return smaller string or pad with spaces).

Then you don't have to worry about it in your code at all, just call:

String s2 = substring_safe (s, 10, 7);

instead of:

String s2 = s.substring (10,7);

This would work in the case that you seem to be worried about (based on your comments to other answers), not breaking the flow of the code when doing lots of string building stuff.

A quick Google search returned this bug: "Bad file descriptor while saving a document w. imported PDFs".

It looks like you need to keep the PDFs to be merged open, until after you have saved and closed the combined PDF.

The closest equivalent to Java's toString is to implement __str__ for your class. Put this in your class definition:

def __str__(self):
     return "foo"

You may also want to implement __repr__ to aid in debugging.

You can't do that from the initialization list,

Many people will suggest you use MERGE, but I caution you against it. By default, it doesn't protect you from concurrency and race conditions any more than multiple statements, but it does introduce other dangers:

http://www.mssqltips.com/sqlservertip/3074/use-caution-with-sql-servers-merge-statement/

Even with this "simpler" syntax available, I still prefer this approach (error handling omitted for brevity):

SET TRANSACTION ISOLATION LEVEL SERIALIZABLE;
BEGIN TRANSACTION;
UPDATE dbo.table SET ... WHERE PK = @PK;
IF @@ROWCOUNT = 0
BEGIN
  INSERT dbo.table(PK, ...) SELECT @PK, ...;
END
COMMIT TRANSACTION;

A lot of folks will suggest this way:

SET TRANSACTION ISOLATION LEVEL SERIALIZABLE;
BEGIN TRANSACTION;
IF EXISTS (SELECT 1 FROM dbo.table WHERE PK = @PK)
BEGIN
  UPDATE ...
END
ELSE
BEGIN
  INSERT ...
END
COMMIT TRANSACTION;

But all this accomplishes is ensuring you may need to read the table twice to locate the row(s) to be updated. In the first sample, you will only ever need to locate the row(s) once. (In both cases, if no rows are found from the initial read, an insert occurs.)

Others will suggest this way:

BEGIN TRY
  INSERT ...
END TRY
BEGIN CATCH
  IF ERROR_NUMBER() = 2627
    UPDATE ...
END CATCH

However, this is problematic if for no other reason than letting SQL Server catch exceptions that you could have prevented in the first place is much more expensive, except in the rare scenario where almost every insert fails. I prove as much here:

• http://www.mssqltips.com/sqlservertip/2632/checking-for-potential-constraint-violations-before-entering-sql-server-try-and-catch-logic/
• http://www.sqlperformance.com/2012/08/t-sql-queries/error-handling

Not sure what you think you gain by having a single statement; I don't think you gain anything. MERGE is a single statement but it still has to really perform multiple operations anyway - even though it makes you think it doesn't.

The given answers only work when there are no borders around the table, which is very limiting!

I have a macro in SASS to do this, which fully supports external and internal borders, achieving the same styling as border-collapse: collapse without actually specifying it.

Tested in FF/IE8/Safari/Chrome.

Gives nice rounded borders in pure CSS in all browsers but IE8 (degrades gracefully) since IE8 doesn't support border-radius :(

Some older browsers may require vendor prefixes to work with border-radius, so feel free to add those prefixes to your code as necessary.

This answer is not the shortest - but it works.

.roundedTable {
  border-radius: 20px / 20px;
  border: 1px solid #333333;
  border-spacing: 0px;
}
.roundedTable th {
  padding: 4px;
  background: #ffcc11;
  border-left: 1px solid #333333;
}
.roundedTable th:first-child {
  border-left: none;
  border-top-left-radius: 20px;
}
.roundedTable th:last-child {
  border-top-right-radius: 20px;
}
.roundedTable tr td {
  border: 1px solid #333333;
  border-right: none;
  border-bottom: none;
  padding: 4px;
}
.roundedTable tr td:first-child {
  border-left: none;
}

To apply this style simply change your

<table>

tag to the following:

<table class="roundedTable">

and be sure to include the above CSS styles in your HTML.

Hope this helps.

I've developed the interpy package, that enables string interpolation in Python.

Just install it via pip install interpy. And then, add the line # coding: interpy at the beginning of your files!

Example:

#!/usr/bin/env python
# coding: interpy

name = "Spongebob Squarepants"
print "Who lives in a Pineapple under the sea? \n#{name}."

All the answers here seem to suggest setting the daylite parameter to false. This is incorrect for many timezones which change abbreviated names depending on the time of the year (e.g. EST vs EDT).

The solution below will give you the correct abbreviation according to the current date for the timezone.

val tz = TimeZone.getDefault()
val isDaylite = tz.inDaylightTime(Date())
val timezone = tz.getDisplayName(isDaylite, TimeZone.SHORT)

You can redirect standard input and use a StreamWriter to write to it:

        Process p = new Process();
        ProcessStartInfo info = new ProcessStartInfo();
        info.FileName = "cmd.exe";
        info.RedirectStandardInput = true;
        info.UseShellExecute = false;

        p.StartInfo = info;
        p.Start();

        using (StreamWriter sw = p.StandardInput)
        {
            if (sw.BaseStream.CanWrite)
            {
                sw.WriteLine("mysql -u root -p");
                sw.WriteLine("mypassword");
                sw.WriteLine("use mydb;");
            }
        }

Use expression(delta) where 'delta' for lowercase d and 'Delta' to get capital ?.

Here's full list of Greek characters:

? a alpha
? ß beta
G ? gamma
? d delta
? e epsilon
? ? zeta
? ? eta
T ? theta
? ? iota
? ? kappa
? ? lambda
? µ mu
? ? nu
? ? xi
? ? omicron
? p pi
? ? rho
S s sigma
? t tau
? ? upsilon
F f phi
? ? chi
? ? psi
O ? omega

EDIT: Copied from comments, when using in conjunction with other words use like: expression(Delta*"price")

Use System.Windows.Forms.Timer.

private Timer timer1; 
public void InitTimer()
{
    timer1 = new Timer();
    timer1.Tick += new EventHandler(timer1_Tick);
    timer1.Interval = 2000; // in miliseconds
    timer1.Start();
}

private void timer1_Tick(object sender, EventArgs e)
{
    isonline();
}

You can call InitTimer() in Form1_Load().

sans SEQUENCE, works only on 8.4:

select * from comments c
join 
(
    select id, row_number() over() as id_sorter  
    from (select unnest(ARRAY[1,3,2,4]) as id) as y
) x on x.id = c.id
order by x.id_sorter

How about:

foreach(var s in listBox1.Items.ToArray())
{
    MessageBox.Show(s);
    //do stuff with (s);
    listBox1.Items.Remove(s);
}

The ToArray makes a copy of the list, so you don't need to worry about it changing the list while you are processing it.

I was having this same issue while my JAVA_HOME system variable was pointing to C:\Program Files\Java\jdk1.8.0_171\bin and my PATH entry consisted of just %JAVA_HOME%.

I changed my JAVA_HOME variable to exclude the bin folder (C:\Program Files\Java\jdk1.8.0_171), and added the bin folder to the system PATH variable: %JAVA_HOME%\bin,

One more way to count words in a string. This code counts words that contain only alphanumeric characters and "_", "’", "-", "'" chars.

function countWords(str) {
  var matches = str.match(/[\w\d\’\'-]+/gi);
  return matches ? matches.length : 0;
}

Dealing with colour sequences can get messy and different systems might use different Colour Sequence Indicators.

I would suggest you try using ncurses. Other than colour, ncurses can do many other neat things with console UI.

What is monkey patching? Monkey patching is a technique used to dynamically update the behavior of a piece of code at run-time.

Why use monkey patching? It allows us to modify or extend the behavior of libraries, modules, classes or methods at runtime without actually modifying the source code

Conclusion Monkey patching is a cool technique and now we have learned how to do that in Python. However, as we discussed, it has its own drawbacks and should be used carefully.

For more info Please refer [1]: https://medium.com/@nagillavenkatesh1234/monkey-patching-in-python-explained-with-examples-25eed0aea505

try setting the display to block in your javascript instead of a blank value.

I adapted regex to work with JSON.

First, stringify the JSON object. Then, you need to store the starts and lengths of the matched substrings. For example:

"matched".search("ch") // yields 3

For a JSON string, this works exactly the same (unless you are searching explicitly for commas and curly brackets in which case I'd recommend some prior transform of your JSON object before performing regex (i.e. think :, {, }).

Next, you need to reconstruct the JSON object. The algorithm I authored does this by detecting JSON syntax by recursively going backwards from the match index. For instance, the pseudo code might look as follows:

find the next key preceding the match index, call this theKey
then find the number of all occurrences of this key preceding theKey, call this theNumber
using the number of occurrences of all keys with same name as theKey up to position of theKey, traverse the object until keys named theKey has been discovered theNumber times
return this object called parentChain

With this information, it is possible to use regex to filter a JSON object to return the key, the value, and the parent object chain.

You can see the library and code I authored at http://json.spiritway.co/

FWIW, you can provide an error message like so:

USERNAME=${1:?"Specify a username"}

This displays a message like this and exits with code 1:

./myscript.sh
./myscript.sh: line 2: 1: Specify a username

A more complete example of everything:

#!/bin/bash
ACTION=${1:?"Specify 'action' as argv[1]"}
DIRNAME=${2:-$PWD}
OUTPUT_DIR=${3:-${HOMEDIR:-"/tmp"}}

echo "$ACTION"
echo "$DIRNAME"
echo "$OUTPUT_DIR"

Output:

$ ./script.sh foo
foo
/path/to/pwd
/tmp

$ export HOMEDIR=/home/myuser
$ ./script.sh foo
foo
/path/to/pwd
/home/myuser

• $ACTION takes the value of the first argument, and exits if empty
• $DIRNAME is the 2nd argument, and defaults to the current directory
• $OUTPUT_DIR is the 3rd argument, or $HOMEDIR (if defined), else, /tmp. This works on OS X, but I'm not positive that it's portable.

first get the profiler Exe from: http://expressprofiler.codeplex.com

then you can add it simply to the Management studio:

Tools -> External tools... ->

a- locate the exe file on your disk (If installed, it's typically C:\Program Files (x86)\ExpressProfiler\ExpressProfiler.exe)

b- give it a name e.g. Express Profiler

that's it :) you have your Profiler with your sql express edition

Older topic but one still relevant. Another issue occurs when an index has become fragmented to the extent of becoming more of a problem than a help. In such a case, the answer would be to rebuild or drop and recreate the index and issuing the delete statement again.

I have my sample code working but want to make it somewhat more better refrencing the tab from list:

Public Class Form1
    Dim State1 As Integer = 1
    Dim AllTabs As List(Of TabPage) = New List(Of TabPage)

    Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
        Check1(State1)
        State1 = CInt(IIf(State1 = 1, 0, 1))
    End Sub

    Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        AllTabs.Add(TabControl1.TabPages("TabPage1"))
        AllTabs.Add(TabControl1.TabPages("TabPage2"))
    End Sub

    Sub Check1(ByVal No As Integer)
        If TabControl1.TabPages.ContainsKey("TabPage1") Then
            TabControl1.TabPages.Remove(TabControl1.TabPages("TabPage1"))
        End If
        If TabControl1.TabPages.ContainsKey("TabPage2") Then
            TabControl1.TabPages.Remove(TabControl1.TabPages("TabPage2"))
        End If
        TabControl1.TabPages.Add(AllTabs(No))
    End Sub
End Class

Mindprod points out that this is not a straightforward question to answer:

A JVM is free to store data any way it pleases internally, big or little endian, with any amount of padding or overhead, though primitives must behave as if they had the official sizes.
For example, the JVM or native compiler might decide to store a boolean[] in 64-bit long chunks like a BitSet. It does not have to tell you, so long as the program gives the same answers.

• It might allocate some temporary Objects on the stack.
• It may optimize some variables or method calls totally out of existence replacing them with constants.
• It might version methods or loops, i.e. compile two versions of a method, each optimized for a certain situation, then decide up front which one to call.

Then of course the hardware and OS have multilayer caches, on chip-cache, SRAM cache, DRAM cache, ordinary RAM working set and backing store on disk. Your data may be duplicated at every cache level. All this complexity means you can only very roughly predict RAM consumption.

Measurement methods

You can use Instrumentation.getObjectSize() to obtain an estimate of the storage consumed by an object.

To visualize the actual object layout, footprint, and references, you can use the JOL (Java Object Layout) tool.

Object headers and Object references

In a modern 64-bit JDK, an object has a 12-byte header, padded to a multiple of 8 bytes, so the minimum object size is 16 bytes. For 32-bit JVMs, the overhead is 8 bytes, padded to a multiple of 4 bytes. (From Dmitry Spikhalskiy's answer, Jayen's answer, and JavaWorld.)

Typically, references are 4 bytes on 32bit platforms or on 64bit platforms up to -Xmx32G; and 8 bytes above 32Gb (-Xmx32G). (See compressed object references.)

As a result, a 64-bit JVM would typically require 30-50% more heap space. (Should I use a 32- or a 64-bit JVM?, 2012, JDK 1.7)

Boxed types, arrays, and strings

Boxed wrappers have overhead compared to primitive types (from JavaWorld):

• Integer: The 16-byte result is a little worse than I expected because an int value can fit into just 4 extra bytes. Using an Integer costs me a 300 percent memory overhead compared to when I can store the value as a primitive type

• Long: 16 bytes also: Clearly, actual object size on the heap is subject to low-level memory alignment done by a particular JVM implementation for a particular CPU type. It looks like a Long is 8 bytes of Object overhead, plus 8 bytes more for the actual long value. In contrast, Integer had an unused 4-byte hole, most likely because the JVM I use forces object alignment on an 8-byte word boundary.

Other containers are costly too:

• Multidimensional arrays: it offers another surprise.
  Developers commonly employ constructs like int[dim1][dim2] in numerical and scientific computing.

  In an int[dim1][dim2] array instance, every nested int[dim2] array is an Object in its own right. Each adds the usual 16-byte array overhead. When I don't need a triangular or ragged array, that represents pure overhead. The impact grows when array dimensions greatly differ.

  For example, a int[128][2] instance takes 3,600 bytes. Compared to the 1,040 bytes an int[256] instance uses (which has the same capacity), 3,600 bytes represent a 246 percent overhead. In the extreme case of byte[256][1], the overhead factor is almost 19! Compare that to the C/C++ situation in which the same syntax does not add any storage overhead.

• String: a String's memory growth tracks its internal char array's growth. However, the String class adds another 24 bytes of overhead.

  For a nonempty String of size 10 characters or less, the added overhead cost relative to useful payload (2 bytes for each char plus 4 bytes for the length), ranges from 100 to 400 percent.

Alignment

Consider this example object:

class X {                      // 8 bytes for reference to the class definition
   int a;                      // 4 bytes
   byte b;                     // 1 byte
   Integer c = new Integer();  // 4 bytes for a reference
}

A naïve sum would suggest that an instance of X would use 17 bytes. However, due to alignment (also called padding), the JVM allocates the memory in multiples of 8 bytes, so instead of 17 bytes it would allocate 24 bytes.

You should change the

<a href="#">My Link</a>

to

<a href="javascript:;">My Link</a>

This way when the link is clicked the page won't scroll to top. This is cleaner than using href="#" and then preventing the default event from running.

I have good reasons for this on the first answer to this question, like the return false; will not execute if the called function throws an error, or you may add the return false; to a doSomething() function and then forget to use return doSomething();

Save the following script as something like findPK.sql.

set verify off
accept TABLE_NAME char prompt 'Table name>'

SELECT cols.column_name
FROM all_constraints cons NATURAL JOIN all_cons_columns cols
WHERE cons.constraint_type = 'P' AND table_name = UPPER('&TABLE_NAME');

It can then be called using

@findPK

Simplay you can place HTML select attribute to option a like shown below

Define the attributes like selected="selected"

<select>
   <option selected="selected">a</option>
   <option>b</option>
   <option>c</option>
</select>

For legend labels can use something like below. Legendlabels are the plot lines saved. modFreq are where the name of the actual labels corresponding to the plot lines. Then the third parameter is the location of the legend. Lastly, you can pass in any arguments as I've down here but mainly need the first three. Also, you are supposed to if you set the labels correctly in the plot command. To just call legend with the location parameter and it finds the labels in each of the lines. I have had better luck making my own legend as below. Seems to work in all cases where have never seemed to get the other way going properly. If you don't understand let me know:

legendLabels = []
for i in range(modSize):
    legendLabels.append(ax.plot(x,hstack((array([0]),actSum[j,semi,i,semi])), color=plotColor[i%8], dashes=dashes[i%4])[0]) #linestyle=dashs[i%4]       
legArgs = dict(title='AM Templates (Hz)',bbox_to_anchor=[.4,1.05],borderpad=0.1,labelspacing=0,handlelength=1.8,handletextpad=0.05,frameon=False,ncol=4, columnspacing=0.02) #ncol,numpoints,columnspacing,title,bbox_transform,prop
leg = ax.legend(tuple(legendLabels),tuple(modFreq),'upper center',**legArgs)
leg.get_title().set_fontsize(tick_size)

You can also use the leg to change fontsizes or nearly any parameter of the legend.

Global title as stated in the above comment can be done with adding text per the link provided: http://matplotlib.sourceforge.net/examples/pylab_examples/newscalarformatter_demo.html

f.text(0.5,0.975,'The new formatter, default settings',horizontalalignment='center',
       verticalalignment='top')

I would like to suggest to use a single RecyclerView and populate your list items dynamically. I've added a github project to describe how this can be done. You might have a look. While the other solutions will work just fine, I would like to suggest, this is a much faster and efficient way of showing multiple lists in a RecyclerView.

The idea is to add logic in your onCreateViewHolder and onBindViewHolder method so that you can inflate proper view for the exact positions in your RecyclerView.

I've added a sample project along with that wiki too. You might clone and check what it does. For convenience, I am posting the adapter that I have used.

public class DynamicListAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {

    private static final int FOOTER_VIEW = 1;
    private static final int FIRST_LIST_ITEM_VIEW = 2;
    private static final int FIRST_LIST_HEADER_VIEW = 3;
    private static final int SECOND_LIST_ITEM_VIEW = 4;
    private static final int SECOND_LIST_HEADER_VIEW = 5;

    private ArrayList<ListObject> firstList = new ArrayList<ListObject>();
    private ArrayList<ListObject> secondList = new ArrayList<ListObject>();

    public DynamicListAdapter() {
    }

    public void setFirstList(ArrayList<ListObject> firstList) {
        this.firstList = firstList;
    }

    public void setSecondList(ArrayList<ListObject> secondList) {
        this.secondList = secondList;
    }

    public class ViewHolder extends RecyclerView.ViewHolder {
        // List items of first list
        private TextView mTextDescription1;
        private TextView mListItemTitle1;

        // List items of second list
        private TextView mTextDescription2;
        private TextView mListItemTitle2;

        // Element of footer view

There is another way of keeping your items in a single ArrayList of objects so that you can set an attribute tagging the items to indicate which item is from first list and which one belongs to second list. Then pass that ArrayList into your RecyclerView and then implement the logic inside adapter to populate them dynamically.

Hope that helps.

def my_string = "some string"
println "here: " + my_string 

Not quite sure why the answer above needs to go into benchmarks, string buffers, tests, etc.

i just place one image in " d drive-->Data-->IMG". The image name is x.jpg:

And on c# code type

ImageBrush myBrush = new ImageBrush();

myBrush.ImageSource = new BitmapImage(new Uri(BaseUriHelper.GetBaseUri(this), "D:\\Data\\IMG\\x.jpg"));

(please put double slash in between path)

this.Background = myBrush;

finally i got the background..

Using jQuery to auto-convert dates with $.parseJSON

Note: this answer provides a jQuery extension that adds automatic ISO and .net date format support.

Since you're using Asp.net MVC I suspect you're using jQuery on the client side. I suggest you read this blog post that has code how to use $.parseJSON to automatically convert dates for you.

Code supports Asp.net formatted dates like the ones you mentioned as well as ISO formatted dates. All dates will be automatically formatted for you by using $.parseJSON().

By default, Windows makes the root of each drive available (provided you've got Administrator privileges) as (e.g.) \\server\c$. These are known as Administrative Shares.

It is quite an old question but still I don't see any complete answers. So I am posting this solution, hoping that someone struggling with this problem might find it useful. The simplest and most effective solution is to override TextView class' onDraw method. Most implementations I have seen use drawText method to draw the stroke but that approach doesn't account for all the formatting alignment and text wrapping that goes in. And as a result often the stroke and text end up at different places. Following approach uses super.onDraw to draw both the stroke and fill parts of the text so you don't have to bother about rest of the stuff. Here are the steps

1. Extend TextView class
2. Override onDraw method
3. Set paint style to FILL
4. call parent class on Draw to render text in fill mode.
5. save current text color.
6. Set current text color to your stroke color
7. Set paint style to Stroke
8. Set stroke width

9. And call parent class onDraw again to draw the stroke over the previously rendered text.

That is all. This class uses custom XML attributes to enable specifying stroke color and width from the XML layout files. Therefore, you need to add these attributes in your attr.xml file in subfolder 'values' under folder 'res'. Copy and paste the following in your attr.xml file.

<?xml version="1.0" encoding="utf-8"?>
<resources>

    <declare-styleable name="StrokedTextAttrs">
        <attr name="textStrokeColor" format="color"/>    
        <attr name="textStrokeWidth" format="float"/>
    </declare-styleable>                

</resources>

Once you are done with that, you can use the custom StrokedTextView class in your XML layout files and specify stroke color and width as well. Here is an example

<com.example.widgets.StrokedTextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Stroked text sample"
    android:textColor="@android:color/white"
    android:textSize="25sp"
    strokeAttrs:textStrokeColor="@android:color/black"
    strokeAttrs:textStrokeWidth="1.7" />

Remember to replace package name with your project's package name. Also add the xmlns namespace in the layout file in order to use custom XML attributes. You can add the following line in your layout file's root node.

xmlns:strokeAttrs="http://schemas.android.com/apk/res-auto"

We need to remember that the {% endif %} comes after the {% else %}.

So this is an example:

{% if someTest %}
     <p> Something is True </p>
{% else %}
     <p> Something is False </p>
{% endif %}

Well, this is my final solution for a simple db, for Linux:

# Read this before!
#
# * roles in postgres are users, and can be used also as group of users
# * $ROLE_LOCAL will be the user that access the db for maintenance and
#   administration. $ROLE_REMOTE will be the user that access the db from the webapp
# * you have to change '$ROLE_LOCAL', '$ROLE_REMOTE' and '$DB'
#   strings with your desired names
# * it's preferable that $ROLE_LOCAL == $DB

I had the same problem. I decided in a very unexpected way. Just opened the command line as an administrator. And then typed:

pip install numpy

There are a few problems here.

1: onBlur expects a callback, and you are calling renderPasswordConfirmError and using the return value, which is null.

2: you need a place to render the error.

3: you need a flag to track "and I validating", which you would set to true on blur. You can set this to false on focus if you want, depending on your desired behavior.

handleBlur: function () {
  this.setState({validating: true});
},
render: function () {
  return <div>
    ...
    <input
        type="password"
        placeholder="Password (confirm)"
        valueLink={this.linkState('password2')}
        onBlur={this.handleBlur}
     />
    ...
    {this.renderPasswordConfirmError()}
  </div>
},
renderPasswordConfirmError: function() {
  if (this.state.validating && this.state.password !== this.state.password2) {
    return (
      <div>
        <label className="error">Please enter the same password again.</label>
      </div>
    );
  }  
  return null;
},

Try using

MyClass[] myArray = list.ToArray();

Just cast one of the two operands to a float first.

v = (float)s / t;

The cast has higher precedence than the division, so happens before the division.

The other operand will be effectively automatically cast to a float by the compiler because the rules say that if either operand is of floating point type then the operation will be a floating point operation, even if the other operand is integral. Java Language Specification, §4.2.4 and §15.17

Add the key View controller-based status bar appearance to Info.plist file and make it boolean type set to NO.

Insert one line code in viewDidLoad (this works on specific class where it is mentioned)

 [UIApplication sharedApplication].statusBarStyle = UIStatusBarStyleLightContent;

Is this logically possible??.. I guess the approach that you must take is this way :

Str1 ="test123.00"
Str2 ="yes50.00"

This will be impossible to tackle unless you have delimiter in between test and 123.00

eg: Str1 = "test-123.00" 

Then you can split this way

Str2 = Str1.split("-"); 

This will return you an array of words split with "-"

Then you can do parseFloat(Str2[1]) to get the floating value i.e 123.00

That's the error you get when the DLL itself requires another COM server to be registered first or has a dependency on another DLL that's not available. The Regsvr32.exe tool does very little, it calls LoadLibrary() to load the DLL that's passed in the command line argument. Then GetProcAddress() to find the DllRegisterServer() entry point in the DLL. And calls it to leave it up to the COM server to register itself.

What that code does is fairly unguessable. The diagnostic you got is however pretty self-evident from the error code, for some reason this COM server needs another one to be registered first. The error message is crappy, it doesn't tell you what other server it needs. A sad side-effect of the way COM error handling works.

To troubleshoot this, use SysInternals' ProcMon tool. It shows you what registry keys Regsvr32.exe (actually: the COM server) is opening to find the server. Look for accesses to the CLSID key. That gives you a hint what {guid} it is looking for. That still doesn't quite tell you the server DLL, you should compare the trace with one you get from a machine that works. The InprocServer32 key has the DLL path.

pure JS solution that will add preloader, set the background-image and then set it up for garbage collection along with it's event listener:

Short version:

const imageUrl = "https://www.google.com/images/branding/googlelogo/1x/googlelogo_color_272x92dp.png";_x000D_
let bgElement = document.querySelector("body");_x000D_
let preloaderImg = document.createElement("img");_x000D_
preloaderImg.src = imageUrl;_x000D_
_x000D_
preloaderImg.addEventListener('load', (event) => {_x000D_
    bgElement.style.backgroundImage = `url(${imageUrl})`;_x000D_
    preloaderImg = null;_x000D_
});

A bit longer with nice opacity transition:

const imageUrl = "https://www.google.com/images/branding/googlelogo/1x/googlelogo_color_272x92dp.png";_x000D_
let bgElement = document.querySelector(".bg-lazy");_x000D_
bgElement.classList.add("bg-loading");_x000D_
let preloaderImg = document.createElement("img");_x000D_
preloaderImg.src = imageUrl;_x000D_
_x000D_
preloaderImg.addEventListener('load', (event) => {_x000D_
  bgElement.classList.remove("bg-loading");_x000D_
  bgElement.style.backgroundImage = `url(${imageUrl})`;_x000D_
  preloaderImg = null;_x000D_
});

.bg-lazy {_x000D_
  height: 100vh;_x000D_
  width: 100vw;_x000D_
  transition: opacity 1s ease-out;_x000D_
}_x000D_
_x000D_
.bg-loading {_x000D_
  opacity: 0;_x000D_
}

<div class="bg-lazy"></div>

For years we've been using a(n open source) preprocessor for this.

//#switch(target)
case "foo": code;
//#end

Preprocessed files are named Foo.jpp and get processed into Foo.java with an ant script.

Advantage is it is processed into Java that runs on 1.0 (although typically we only supported back to 1.4). Also it was far easier to do this (lots of string switches) compared to fudging it with enums or other workarounds - code was a lot easier to read, maintain, and understand. IIRC (can't provide statistics or technical reasoning at this point) it was also faster than the natural Java equivalents.

Disadvantages are you aren't editing Java so it's a bit more workflow (edit, process, compile/test) plus an IDE will link back to the Java which is a little convoluted (the switch becomes a series of if/else logic steps) and the switch case order is not maintained.

I wouldn't recommend it for 1.7+ but it's useful if you want to program Java that targets earlier JVMs (since Joe public rarely has the latest installed).

You can get it from SVN or browse the code online. You'll need EBuild to build it as-is.

Not with CSS directly, you could set CSS properties via JavaScript based on the internal contents but in the end you would still need to be operating in the definitions of CSS.

public void clear(StringBuilder s) {

Usage:

for readability, I think this is the best solution.

I was getting this error within an ASP.NET application where the WCF service had been added to a class library which is being added to the ASP.NET application as a referenced .dll file in the bin folder. To resolve the error, the config settings in the app.config file within the class library referencing the WCF service needed to be copied into the web.config settings for the ASP.NET site/app.

You need to use dynamic SQL to achieve this; something like:

DECLARE
    TYPE cur_type IS REF CURSOR;

    CURSOR client_cur IS
        SELECT DISTING username
        FROM all_users
        WHERE length(username) = 3;

    emails_cur cur_type;
    l_cur_string VARCHAR2(128);
    l_email_id <type>;
    l_name <type>;
BEGIN
    FOR client IN client_cur LOOP
        dbms_output.put_line('Client is '|| client.username);
        l_cur_string := 'SELECT id, name FROM '
            || client.username || '.org';
        OPEN emails_cur FOR l_cur_string;
        LOOP
            FETCH emails_cur INTO l_email_id, l_name;
            EXIT WHEN emails_cur%NOTFOUND;
            dbms_output.put_line('Org id is ' || l_email_id
                || ' org name ' || l_name);
        END LOOP;
        CLOSE emails_cur;
    END LOOP;
END;
/

Edited to correct two errors, and to add links to 10g documentation for OPEN-FOR and an example. Edited to make the inner cursor query a string variable.

As I wrote in my comment, the solution to your problem is to write the following:

Set hyperLinkText = hprlink.Range

Set is needed because TextRange is a class, so hyperLinkText is an object; as such, if you want to assign it, you need to make it point to the actual object that you need.
