You need to use $scope.$apply() if you want to make any changes to a scope value from outside the control of angularjs like a jquery/javascript event handler.

function change() {
    alert("a");
    var scope = angular.element($("#outer")).scope();
    scope.$apply(function(){
        scope.msg = 'Superhero';
    })
}

Demo: Fiddle

You can use + if you know all the values are strings. Jinja also provides the ~ operator, which will ensure all values are converted to string first.

{% set my_string = my_string ~ stuff ~ ', '%}

check it

const mq = window.matchMedia( "(min-width: 500px)" );

if (mq.matches) {
  // window width is at least 500px
} else {
  // window width is less than 500px
}

ensure_ascii=False really only defers the issue to the decoding stage:

>>> dict2 = {'LeafTemps': '\xff\xff\xff\xff',}
>>> json1 = json.dumps(dict2, ensure_ascii=False)
>>> print(json1)
{"LeafTemps": "????"}
>>> json.loads(json1)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.7/json/__init__.py", line 328, in loads
    return _default_decoder.decode(s)
  File "/usr/lib/python2.7/json/decoder.py", line 365, in decode
    obj, end = self.raw_decode(s, idx=_w(s, 0).end())
  File "/usr/lib/python2.7/json/decoder.py", line 381, in raw_decode
    obj, end = self.scan_once(s, idx)
UnicodeDecodeError: 'utf8' codec can't decode byte 0xff in position 0: invalid start byte

Ultimately you can't store raw bytes in a JSON document, so you'll want to use some means of unambiguously encoding a sequence of arbitrary bytes as an ASCII string - such as base64.

>>> import json
>>> from base64 import b64encode, b64decode
>>> my_dict = {'LeafTemps': '\xff\xff\xff\xff',} 
>>> my_dict['LeafTemps'] = b64encode(my_dict['LeafTemps'])
>>> json.dumps(my_dict)
'{"LeafTemps": "/////w=="}'
>>> json.loads(json.dumps(my_dict))
{u'LeafTemps': u'/////w=='}
>>> new_dict = json.loads(json.dumps(my_dict))
>>> new_dict['LeafTemps'] = b64decode(new_dict['LeafTemps'])
>>> print new_dict
{u'LeafTemps': '\xff\xff\xff\xff'}

It sounds like you're trying to link with your resulting object file with gcc instead of g++:

Note that programs using C++ object files must always be linked with g++, in order to supply the appropriate C++ libraries. Attempting to link a C++ object file with the C compiler gcc will cause "undefined reference" errors for C++ standard library functions:

$ g++ -Wall -c hello.cc
$ gcc hello.o       (should use g++)
hello.o: In function `main':
hello.o(.text+0x1b): undefined reference to `std::cout'
.....
hello.o(.eh_frame+0x11):
  undefined reference to `__gxx_personality_v0'

Source: An Introduction to GCC - for the GNU compilers gcc and g++

The other answer is very complete, but here is a rule of thumb:

• call is blocking:

  call('notepad.exe')
  print('hello')  # only executed when notepad is closed
  

• Popen is non-blocking:

  Popen('notepad.exe')
  print('hello')  # immediately executed
  

A cleaner way of iterating the lists is:

// initialise the collection
collection = new ArrayList<ArrayList<String>>();
// iterate
for (ArrayList<String> innerList : collection) {
    for (String string : innerList) {
        // do stuff with string
    }
}

Well, there is no shortcut to do it as per my findings, but somehow you
an achieve it in few simple steps

First you have to declare a bean of type 'ProtobufJsonFormatHttpMessageConverter'

@Bean  
@Primary  
public ProtobufJsonFormatHttpMessageConverter protobufHttpMessageConverter() {  
  return new ProtobufJsonFormatHttpMessageConverter(JsonFormat.parser(), JsonFormat.printer());  
}  

Then you can just write an Utility class like ResponseBuilder, because it can parse the request by default but without these changes it can not produce Json response. and then you can write few methods to convert the response types to its related object type.

public static <T> T build(Message message, Class<T> type) {
  Printer printer = JsonFormat.printer();
  Gson gson = new Gson();
  try {
    return gson.fromJson(printer.print(message), type);
  } catch (JsonSyntaxException | InvalidProtocolBufferException e) {
    throw new ApiException(HttpStatus.INTERNAL_SERVER_ERROR, "Response   conversion Error", e);
  }
}

Then you can call this method from your controller class as last line like -

return ResponseBuilder.build(<returned_service_object>, <Type>);

Hope this will help you to implement protobuf in json format.

Using the Random class is the way to go as suggested in the accepted answer, but here is a less straight-forward correct way of doing it if you didn't want to create a new Random object :

min + (int) (Math.random() * (max - min + 1));

You have one choice hide your back button and make it with your self. Then set its color.

I did that:

self.navigationItem.setHidesBackButton(true, animated: true)
let backbtn = UIBarButtonItem(title: "Back", style:UIBarButtonItemStyle.Plain, target: self, action: "backTapped:")
self.navigationItem.leftBarButtonItem = backbtn
self.navigationItem.leftBarButtonItem?.tintColor = UIColor.grayColor()

From CSS-Tricks... there is a one step way to do this without z-indexing and adding pseudo elements-- requires linear gradient which I think means you need CSS3 support

.tinted-image {
  background-image: 
    /* top, transparent red */
    linear-gradient(
      rgba(255, 0, 0, 0.45), 
      rgba(255, 0, 0, 0.45)
    ),
    /* your image */
    url(image.jpg);
}

The easiest way in recent browsers would be to use the appropriate GlobalEventHandlers, onDOMContentLoaded, onload, onloadeddata (...)

onDOMContentLoaded = (function(){ console.log("DOM ready!") })()_x000D_
_x000D_
onload = (function(){ console.log("Page fully loaded!") })()_x000D_
_x000D_
onloadeddata = (function(){ console.log("Data loaded!") })()

The DOMContentLoaded event is fired when the initial HTML document has been completely loaded and parsed, without waiting for stylesheets, images, and subframes to finish loading. A very different event load should be used only to detect a fully-loaded page. It is an incredibly popular mistake to use load where DOMContentLoaded would be much more appropriate, so be cautious.

https://developer.mozilla.org/en-US/docs/Web/Events/DOMContentLoaded

The function used is an IIFE, very useful on this case, as it trigger itself when ready:

https://en.wikipedia.org/wiki/Immediately-invoked_function_expression

It is obviously more appropriate to place it at the end of any scripts.

In ES6, we can also write it as an arrow function:

onload = (() => { console.log("ES6 page fully loaded!") })()

The best is to use the DOM elements, we can wait for any variable to be ready, that trigger an arrowed IIFE.

The behavior will be the same, but with less memory impact.

footer = (() => { console.log("Footer loaded!") })()

<div id="footer">

In many cases, the document object is also triggering when ready, at least in my browser. The syntax is then very nice, but it need further testings about compatibilities.

document=(()=>{    /*Ready*/   })()

Moment js solution to this is

var d = new Date(new Date().setHours(0,0,0,0));
m.add(m.utcOffset(), 'm')
m.toDate().toISOString()
// output "2019-07-18T00:00:00.000Z"

wget -O- http://www.example.com/cronit.php >> /dev/null

This means send the file to stdout, and send stdout to /dev/null

The res.header('Access-Control-Allow-Origin', '*'); wouldn't work with Autorization header. Just enable pre-flight request, using cors library:

var express = require('express')
var cors = require('cors')
var app = express()
app.use(cors())
app.options('*', cors())

Try:

select right ('0'+convert(nvarchar(2), DATEPART(mm, getdate())),2 )

You got a ninja ')'.

Try :

<div *ngIf="currentStatus !== 'open' || currentStatus !== 'reopen'">

The simple solution is to put it in an iframe and hope that the user has a plug-in that supports it.

(I don't, the Acrobat plugin has been such a resource hog and source of instability that I make a point to remove it from any browser that it touches).

The complicated, but relative popular solution is to display it in a flash applet.

SQL Server Reporting Services (SSRS)
SSRS can remain active even if you uninstall SQL Server.
To stop the service:

Open SQL Server Configuration Manager. Select “SQL Server Services” in the left-hand pane. Double-click “SQL Server Reporting Services”. Hit Stop. Switch to the Service tab and set the Start Mode to “Manual”.

Skype
Irritatingly, Skype can switch to port 80. To disable it, select
Tools > Options > Advanced > Connection then uncheck
“Use port 80 and 443 as alternatives for incoming connections”.

IIS (Microsoft Internet Information Server)

For Windows 7 (or vista) its the most likely culprit. You can stop the service from the command line.

Open command line cmd.exe and type:

net stop was /y

For older versions of Windows type:

net stop iisadmin /y

Other

If this does not solve the problem further detective work is necessary if IIS, SSRS and Skype are not to blame. Enter the following on the command line:

netstat -ao

The active TCP addresses and ports will be listed. Locate the line with local address “0.0.0.0:80" and note the PID value. Start Task Manager. Navigate to the Processes tab and, if necessary, click View > Select Columns to ensure “PID (Process Identifier)” is checked. You can now locate the PID you noted above. The description and properties should help you determine which application is using the port.

UPDATE Table
SET DateColumn=GETDATE()
WHERE UserID=@UserID

If you're inserting into a table, and will always need to put the current date, I would recommend setting GETDATE() as the default value for that column, and don't allow NULLs

"Objects" are NEVER passed in C# -- "objects" are not values in the language. The only types in the language are primitive types, struct types, etc. and reference types. No "object types".

The types Object, MyClass, etc. are reference types. Their values are "references" -- pointers to objects. Objects can only be manipulated through references -- when you do new on them, you get a reference, the . operator operates on a reference; etc. There is no way to get a variable whose value "is" an object, because there are no object types.

All types, including reference types, can be passed by value or by reference. A parameter is passed by reference if it has a keyword like ref or out. The SetObject method's obj parameter (which is of a reference type) does not have such a keyword, so it is passed by value -- the reference is passed by value.

Your choofdlog holds a FileName and FileNames (for multi-selection) containing the file paths, after the ShowDialog() returns.

A simple solution that works with Ubuntu, but may fix the problem on windows too:

Just call

pip install --upgrade pip

You could use a simple Union + Distinct:

var lines = lines2.Union(lines3).Distinct();

That will add all the items from the second list into the first list, and then return all the unique strings in the combined list. Not likely to perform well with large lists, but it's simple.

This is a complementary answer for the specific case of you using AWS cloud computing (either EC2 or RDS machines).

Besides doing everything proposed above, when using AWS cloud computing you will need to set you inbound rules in a way that let you access to the ports. Please check this post, which is valid for EC2 and RDS.

Not a direct answer to your question, but you can get the most commonly used utilities from http://www.mingw.org/ without having to jump through the hoops with that horrible Cygwin installer.

Here is a slightly more informative link http://sourceforge.net/apps/mediawiki/cobcurses/index.php?title=Install-MSYS.

you just need to run the command as a super user:

just type from the terminal: sudo su mongod

You likely want File.toPath().

JavaScript only has a Number type that stores floating point values.

There is no int.

Edit:

If you want to format the number as a string with two digits after the decimal point use:

(4).toFixed(2)

Not directly related, unless you have similar code but I just noticed a strange behaviour to form-inline, bootstrap 3.3.7

I did not use row and cells for this as it is a desktop project, if the opening tag was below table (in this case):

<table class="form-inline"> 
<form> 
<tr>

Form elements would stack.

Switch and it properly lined up.

<form>
<table class="form-inline">
<tr>

Safari 10.0.2 and latest Chrome did not make any differences. Maybe my layout was wrong but it is not very forgiving.

try to fix type="JavaScript" to type="text/javascript" in you vue.js srcipt tag, or just remove it. Modern browsers will take script tag as javascript as default.

With '' element usually we use 'value' attribute. It will make it easier to set then:

$('select').val('option-value');

VonC mentioned in his answer how to remote debug from Eclipse.

I would like to add that the JAVA_OPTS settings are already in run.conf.bat. You just have to uncomment them:

in JBOSS_HOME\bin\run.conf.bat on Windows:

rem # Sample JPDA settings for remote socket debugging
set "JAVA_OPTS=%JAVA_OPTS% -Xrunjdwp:transport=dt_socket,address=8787,server=y,suspend=n"

The Linux version is similar and is located at JBOSS_HOME/bin/run.conf

You can do this in Interface Builder.

Select the UIButton you wish to set in IB then go to the attributes inspector.

In the screen shots,I am using a custom button type , but that does not matter.

The <a href="#!">Link</a> and <a href="#/">Link</a> does not work if one has to click on the same input more than once.. it only takes in 1 event click for each on multiple inputs.

still the best way to go is with <a href="#">Link</a>

then,

event.preventDefault();

Take some base date which is the 31st of some month e.g. '20011231'. Then use the
following procedure (I have given 3 identical examples below, only the @dt value differs).

declare @dt datetime;

set @dt = '20140312'

SELECT DATEADD(month, DATEDIFF(month, '20011231', @dt), '20011231');



set @dt = '20140208'

SELECT DATEADD(month, DATEDIFF(month, '20011231', @dt), '20011231');



set @dt = '20140405'

SELECT DATEADD(month, DATEDIFF(month, '20011231', @dt), '20011231');

Here's an example that actually filters for BIN files. Also Windows now want you to save files to user locations, not system locations, so here's an example (you can use intellisense to browse the other options):

            var saveFileDialog = new Microsoft.Win32.SaveFileDialog()
            {
                DefaultExt = "*.xml",
                Filter = "BIN Files (*.bin)|*.bin",
                InitialDirectory = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments),
            };

            var result = saveFileDialog.ShowDialog();
            if (result != null && result == true)
            {
                // Save the file here
            }

There is also a nice nuget package. It will pull the dll to your packages folder. You will need to add the reference to the dll manually.

NOTE: This package is not an official Microsoft package.

Thank you all for responding. After a further investigation I got to the right answer. As mentioned by Skip Head, the TimeStamped I was getting from my application was being adjusted to the user's TimeZone. So if the User entered 6:12 PM (EST) I would get 2:12 PM (GMT). What I needed was a way to undo the conversion so that the time entered by the user is the time I sent to the WebServer request. Here's how I accomplished this:

// Get TimeZone of user
TimeZone currentTimeZone = sc_.getTimeZone();
Calendar currentDt = new GregorianCalendar(currentTimeZone, EN_US_LOCALE);
// Get the Offset from GMT taking DST into account
int gmtOffset = currentTimeZone.getOffset(
    currentDt.get(Calendar.ERA), 
    currentDt.get(Calendar.YEAR), 
    currentDt.get(Calendar.MONTH), 
    currentDt.get(Calendar.DAY_OF_MONTH), 
    currentDt.get(Calendar.DAY_OF_WEEK), 
    currentDt.get(Calendar.MILLISECOND));
// convert to hours
gmtOffset = gmtOffset / (60*60*1000);
System.out.println("Current User's TimeZone: " + currentTimeZone.getID());
System.out.println("Current Offset from GMT (in hrs):" + gmtOffset);
// Get TS from User Input
Timestamp issuedDate = (Timestamp) getACPValue(inputs_, "issuedDate");
System.out.println("TS from ACP: " + issuedDate);
// Set TS into Calendar
Calendar issueDate = convertTimestampToJavaCalendar(issuedDate);
// Adjust for GMT (note the offset negation)
issueDate.add(Calendar.HOUR_OF_DAY, -gmtOffset);
System.out.println("Calendar Date converted from TS using GMT and US_EN Locale: "
    + DateFormat.getDateTimeInstance(DateFormat.SHORT, DateFormat.SHORT)
    .format(issueDate.getTime()));

The code's output is: (User entered 5/1/2008 6:12PM (EST)

Current User's TimeZone: EST
Current Offset from GMT (in hrs):-4 (Normally -5, except is DST adjusted)
TS from ACP: 2008-05-01 14:12:00.0
Calendar Date converted from TS using GMT and US_EN Locale: 5/1/08 6:12 PM (GMT)

An additional trick beside using =COUNTIF(...) and =COUNTA(...) is:

=COUNTBLANK(A2:C100)

That will count all the empty cells.

This is useful for:

• empty cells that doesn't contain data
• formula that return blank or null
• survey with missing answer fields which can be used for diff criterias

What he wants to say is:

"If you have two classes which share most of the same properties you can cast an object from class a to class b and automatically make the system understand the assignment via the shared property names?"

Option 1: Use reflection

Disadvantage : It's gonna slow you down more than you think.

Option 2: Make one class derive from another, the first one with common properties and other an extension of that.

Disadvantage: Coupled! if your're doing that for two layers in your application then the two layers will be coupled!

Let there be:

class customer
{
    public string firstname { get; set; }
    public string lastname { get; set; }
    public int age { get; set; }
}
class employee
{
    public string firstname { get; set; }
    public int age { get; set; } 
}

Now here is an extension for Object type:

public static T Cast<T>(this Object myobj)
{
    Type objectType = myobj.GetType();
    Type target = typeof(T);
    var x = Activator.CreateInstance(target, false);
    var z = from source in objectType.GetMembers().ToList()
        where source.MemberType == MemberTypes.Property select source ;
    var d = from source in target.GetMembers().ToList()
        where source.MemberType == MemberTypes.Property select source;
    List<MemberInfo> members = d.Where(memberInfo => d.Select(c => c.Name)
       .ToList().Contains(memberInfo.Name)).ToList();
    PropertyInfo propertyInfo;
    object value;
    foreach (var memberInfo in members)
    {
        propertyInfo = typeof(T).GetProperty(memberInfo.Name);
        value = myobj.GetType().GetProperty(memberInfo.Name).GetValue(myobj,null);

        propertyInfo.SetValue(x,value,null);
    }   
    return (T)x;
}  

Now you use it like this:

static void Main(string[] args)
{
    var cus = new customer();
    cus.firstname = "John";
    cus.age = 3;
    employee emp =  cus.Cast<employee>();
}

Method cast checks common properties between two objects and does the assignment automatically.

Simplest answer is:

Step 1: Fire up Terminal.app

Step 2: Type nano .bash_profile – This command will open the .bash_profile document (or create it if it doesn’t already exist) in the easiest to use text editor in Terminal – Nano.

Step 3: Now you can make a simple change to the file. Paste these lines of code to change your Terminal prompt.

export PS1="___________________ | \w @ \h (\u) \n| => "

export PS2="| => "

Step 4: Now save your changes by typing ctrl +o Hit return to save. Then exit Nano by typing ctrl+x

Step 5: Now we need to *activate your changes. Type source .bash_profile and watch your prompt change.

That's it! Enjoy!

I used mvn eclipse:eclipse -Dwtpversion=2.0 in command line in the folder where I had my pom.xml. Then I refreshed the project in eclipse IDE. After that I was able to add my project.

A more elegant version of Mark Kramer's would be to do the following:

function animateImg(id, gifSrc){
  var $el = $(id),
    staticSrc = $el.attr('src');
  $el.hover(
    function(){
      $(this).attr("src", gifSrc);
    },
    function(){
      $(this).attr("src", staticSrc);
    });
}

$(document).ready(function(){
  animateImg('#id1', 'gif/gif1.gif');
  animateImg('#id2', 'gif/gif2.gif');
});

Or even better would be to use data attributes:

$(document).ready(function(){
  $('.animated-img').each(function(){
    var $el = $(this),
      staticSrc = $el.attr('src'),
      gifSrc = $el.data('gifSrc');
    $el.hover(
      function(){
        $(this).attr("src", gifSrc);
      },
      function(){
        $(this).attr("src", staticSrc);
      });
  });
});

And the img el would look something like:

<img class="animated-img" src=".../img.jpg" data-gif-src=".../gif.gif" />

Note: This code is untested but should work fine.

Position the cursor inside the class, then press ALT + Ins and select Getters and Setters from the contextual menu.

curl_exec is necessary. Try CURLOPT_NOBODY to not download the body. That might be faster.

I agree httpclient is something of a standard - but I guess you are looking for options so...

Restlet provides a http client specially designed for interactong with Restful web services.

Example code:

    Client client = new Client(Protocol.HTTP);
    Request r = new Request();
    r.setResourceRef("http://127.0.0.1:8182/sample");
    r.setMethod(Method.GET);
    r.getClientInfo().getAcceptedMediaTypes().add(new Preference<MediaType>(MediaType.TEXT_XML));
    client.handle(r).getEntity().write(System.out);

See http://www.restlet.org/ for more details

The question in the link you gave talks about naming of JavaScript variables, not about file naming, so forget about that for the context in which you ask your question.

As to file naming, it is purely a matter of preference and taste. I prefer naming files with hyphens because then I don't have to reach for the shift key, as I do when dealing with camelCase file names; and because I don't have to worry about differences between Windows and Linux file names (Windows file names are case-insensitive, at least through XP).

So the answer, like so many, is "it depends" or "it's up to you."

The one rule you should follow is to be consistent in the convention you choose.

As mentioned here, this feature is not currently supported.

sorry to dig this up, I just want to share my idea, the easy way for me is to rename composer.phar to composer.bat and put it into my PATH.

I got a simple and permanent solution for this issue in windows.

Go to network and internet option->

click on Etherenet or wifi(for which you are connected) option ->

Click on change adapter option ->

Right click on the network for which you have connected.

A dialog box will be opened and just click on Internet protocal version (TCP/IPv4) option.

Another dialog box will be opened and there just neglect the first set about the IP address (Keep as it is set) and click radio button of Use the following DNS server addresses: and enter as 8.8.8.8 in Preferred DNS server: and 8.8.4.4 in Alternate DNS server:

Now you can open your emulator whenever and you will get internet in the android emulators.

in Chrome console:

debug(MyFunction)
MyFunction()

I guess it's just because the onblur event is called as a result of the input losing focus, there isn't a blur action associated with an input, like there is a click action associated with a button

JMeter's built-in proxy may be used to record all HTTP request/response information.

Firefox "Live HTTP headers" plugin may be used to see what is happening on the browser side when sending/receiving request.

Firefox "Tamper data" plugin may be useful when you need to intercept and modify request.

Basically, the module cannot be instantiated. When a class includes a module, a proxy superclass is generated that provides access to all the module methods as well as the class methods.

A module can be included by multiple classes. Modules cannot be inherited, but this "mixin" model provides a useful type of "multiple inheritrance". OO purists will disagree with that statement, but don't let purity get in the way of getting the job done.

Just to update, following iOS 13, we now have SceneDelegates. So one might choose to put the desired tab selection in SceneDelegate.swift as follows:

class SceneDelegate: UIResponder, UIWindowSceneDelegate {

    var window: UIWindow?

    func scene(_ scene: UIScene, 
               willConnectTo session: UISceneSession, 
               options connectionOptions: UIScene.ConnectionOptions) {

        guard let _ = (scene as? UIWindowScene) else { return }

        if let tabBarController = self.window!.rootViewController as? UITabBarController {
            tabBarController.selectedIndex = 1
        }

    }

This is one approach:

from xlrd import open_workbook

class Arm(object):
    def __init__(self, id, dsp_name, dsp_code, hub_code, pin_code, pptl):
        self.id = id
        self.dsp_name = dsp_name
        self.dsp_code = dsp_code
        self.hub_code = hub_code
        self.pin_code = pin_code
        self.pptl = pptl

    def __str__(self):
        return("Arm object:\n"
               "  Arm_id = {0}\n"
               "  DSPName = {1}\n"
               "  DSPCode = {2}\n"
               "  HubCode = {3}\n"
               "  PinCode = {4} \n"
               "  PPTL = {5}"
               .format(self.id, self.dsp_name, self.dsp_code,
                       self.hub_code, self.pin_code, self.pptl))

wb = open_workbook('sample.xls')
for sheet in wb.sheets():
    number_of_rows = sheet.nrows
    number_of_columns = sheet.ncols

    items = []

    rows = []
    for row in range(1, number_of_rows):
        values = []
        for col in range(number_of_columns):
            value  = (sheet.cell(row,col).value)
            try:
                value = str(int(value))
            except ValueError:
                pass
            finally:
                values.append(value)
        item = Arm(*values)
        items.append(item)

for item in items:
    print item
    print("Accessing one single value (eg. DSPName): {0}".format(item.dsp_name))
    print

You don't have to use a custom class, you can simply take a dict(). If you use a class however, you can access all values via dot-notation, as you see above.

Here is the output of the script above:

Arm object:
  Arm_id = 1
  DSPName = JaVAS
  DSPCode = 1
  HubCode = AGR
  PinCode = 282001 
  PPTL = 1
Accessing one single value (eg. DSPName): JaVAS

Arm object:
  Arm_id = 2
  DSPName = JaVAS
  DSPCode = 1
  HubCode = AGR
  PinCode = 282002 
  PPTL = 3
Accessing one single value (eg. DSPName): JaVAS

Arm object:
  Arm_id = 3
  DSPName = JaVAS
  DSPCode = 1
  HubCode = AGR
  PinCode = 282003 
  PPTL = 5
Accessing one single value (eg. DSPName): JaVAS

This is a base service class (ServiceBase subclass) that can be subclassed to build a windows service that can be easily installed from the command line, without installutil.exe.

All you have to do is to implement two public/internal methods in your real service:

    new internal  void InstallService()
    {
        base.InstallService();
    }
    new internal void UninstallService()
    {
        base.UninstallService();
    }

and then call them when you want to install the service:

    static void Main(string[] args)
    {
        if (Environment.UserInteractive)
        {
            MyService s1 = new MyService();
            if (args.Length == 1)
            {
                switch (args[0])
                {
                    case "-install":
                        s1.InstallService();

                        break;
                    case "-uninstall":

                        s1.UninstallService();
                        break;
                    default:
                        throw new NotImplementedException();
                }
            }


        }
        else {
            ServiceBase[] ServicesToRun;
            ServicesToRun = new ServiceBase[] 
            { 
                new MyService() 
            };
            ServiceBase.Run(MyService);            
        }

    }

ok guys you are not going to believe me how easy it is, so i putted a video on YouTube to show you that [ click here ]

now , steps :

1. run your xampp control panel
2. click the button saying config
3. select apache( httpd.conf )
4. find document root
5. replace

DocumentRoot "C:/xampp/htdocs" <Directory "C:/xampp/htdocs">

those 2 lines || C:/xampp/htdocs == current location for root || change C:/xampp/htdocs with any location you want

6. save it DONE: start apache and go to the localhost see in action [ watch video click here ]

Using jQuery:

var str = '{"id":1,"name":"Test1"},{"id":2,"name":"Test2"}';
var jsonObj = $.parseJSON('[' + str + ']');

jsonObj is your JSON object.

I'd use <article> for a text block that is totally unrelated to the other blocks on the page. <section>, on the other hand, would be a divider to separate a document which have are related to each other.

Now, i'm not sure what you have in your videos, newsfeed etc, but here's an example (there's no REAL right or wrong, just a guideline of how I use these tags):

<article>
    <h1>People</h1>
    <p>text about people</p>
    <section>
        <h1>fat people</h1>
        <p>text about fat people</p>
    </section>
    <section>
        <h1>skinny people</p>
        <p>text about skinny people</p>
    </section>
</article>
<article>
    <h1>Cars</h1>
    <p>text about cars</p>
    <section>
        <h1>Fast Cars</h1>
        <p>text about fast cars</p>
    </section>
</article>

As you can see, the sections are still relevant to each other, but as long as they're inside a block that groups them. Sections DONT have to be inside articles. They can be in the body of a document, but i use sections in the body, when the whole document is one article.

e.g.

<body>
    <h1>Cars</h1>
    <p>text about cars</p>
    <section>
        <h1>Fast Cars</h1>
        <p>text about fast cars</p>
    </section>
</body>

Hope this makes sense.

Solution that work on IE10: (I needed a csv file, but it's enough to change type and filename to txt)

var csvContent=data; //here we load our csv data 
var blob = new Blob([csvContent],{
    type: "text/csv;charset=utf-8;"
});

navigator.msSaveBlob(blob, "filename.csv")

The most pythonic way would be to use a list comprehension:

l = [2*x for x in l]

If you need to do this for a large number of integers, use numpy arrays:

l = numpy.array(l, dtype=int)*2

A final alternative is to use map

l = list(map(lambda x:2*x, l))

The following code -

element.sendKeys("");

tries to find an input tag box to enter some information, while

new Actions(driver).moveToElement(element).perform();

is more appropriate as it will work for image elements, link elements, dropdown boxes etc.

Therefore using moveToElement() method makes more sense to focus on any generic WebElement on the web page.

For an input box you will have to click() on the element to focus.

new Actions(driver).moveToElement(element).click().perform();

while for links and images the mouse will be over that particular element,you can decide to click() on it depending on what you want to do.

If the click() on an input tag does not work -

Since you want this function to be generic, you first check if the webElement is an input tag or not by -

if("input".equals(element.getTagName()){
   element.sendKeys("");
} 
else{
   new Actions(driver).moveToElement(element).perform();

}

You can make similar changes based on your preferences.

Just do the following step...

Build>Clean Project

after that Run project again, this worked for me

There are other ways to achieve this here: (Plot correlation matrix into a graph), but I like your version with the correlations in the boxes. Is there a way to add the variable names to the x and y column instead of just those index numbers? For me, that would make this a perfect solution. Thanks!

edit: I was trying to comment on the post by [Marc in the box], but I clearly don't know what I'm doing. However, I did manage to answer this question for myself.

if d is the matrix (or the original data frame) and the column names are what you want, then the following works:

axis(1, 1:dim(d)[2], colnames(d), las=2)
axis(2, 1:dim(d)[2], colnames(d), las=2)

las=0 would flip the names back to their normal position, mine were long, so I used las=2 to make them perpendicular to the axis.

edit2: to suppress the image() function printing numbers on the grid (otherwise they overlap your variable labels), add xaxt='n', e.g.:

image(x=seq(dim(x)[2]), y=seq(dim(y)[2]), z=COR, col=rev(heat.colors(20)), xlab="x column", ylab="y column", xaxt='n')

Here's an excellent article by Scott Allen: Developing Gadgets for the Windows Sidebar

This site, Windows 7/Vista Sidebar Gadgets, has links to many gadget resources.

Finally after a lot of tests, I think the most convenient and efficient way to preset is:

var presetValue = "black";
$("input[name=correctAnswer]").filter("[value=" + presetValue + "]").prop("checked",true);
$("input[name=correctAnswer]").button( "refresh" );//JQuery UI only

The refresh is required with the JQueryUI object.

Retrieving the value is easy :

alert($('input[name=correctAnswer]:checked').val())

Tested with JQuery 1.6.1, JQuery UI 1.8.

Another good way to serialize json into c# is below:

RootObject ro = new RootObject();
     try
    {

        StreamReader sr = new StreamReader(FileLoc);
        string jsonString = sr.ReadToEnd();
        JavaScriptSerializer ser = new JavaScriptSerializer();
        ro = ser.Deserialize<RootObject>(jsonString);


   }

you need to add a reference to system.web.extensions in .net 4.0 this is in program files (x86) > reference assemblies> framework> system.web.extensions.dll and you need to be sure you're using just regular 4.0 framework not 4.0 client

TL;DR:

• If no user is found at /users/9, you should return a 404.
• If no user is found at /users?id=9, you should return a 204.

Long Version:

After reviewing my own usage of these status codes and the examples on this post, I would have to say that 404 is the appropriate response if User #9 was Not Found at the url of /users/9.

In my system today, our Application Insights logs are filled with hundreds of logged 404 errors that muddy up our logs all because we decided to return 404's when /users/9 had no correlating data. However, this does not mean our approach was incorrect when setting up our responses, rather, I would propose that it means our approach was incorrect when setting up our routing.

If you're expecting an endpoint to get a lot of traffic and are concerned about logging too many 404 errors, you should change your routing to fall in line with the status code you want, not force a status code to be inappropriately used.

We've since decided to make 2 changes to our code:

1. Change our route to work by expecting /users?id=9
2. Change our error code to 204 so that the 404's don't fill our AI logs.

At the end of the day, the architect of the API needs to understand how their API will be used and what kind of routing will be appropriate for that use case.

I believe that in the case of /users/9, the resource you are requesting is the user itself, User #9; you are asking the server to respond with an object identified as "9" that happens to exist in a path that has the word 'user' in it. If that object was not found, you should get a 404.

However, if you call /users?id=9, I feel that the resource you are requesting is the Users controller while also providing a bit more specificity so that it doesn't return a full list of all users. You are asking the server to respond with a specific user who can be identified by an ID number defined in the query string. Thusly, if no data was found, it makes sense to me that a 204 would be applicable because even if no data was found, the controller was.

The query string approach also accomplishes something that I think helps not only the API developers but also the client developers (especially junior developers or future developers who inherit this code, or code that makes calls to it):

It becomes immediately clear to anyone involved that 9 is an ID, not some arbitrary number. This point may seem moot in such a basic example, but consider a system that uses GUIDs as row ID's or allows you to get data by a person's name, or even a system that is returning info for specific ZIP/postal codes instead of row ID's. It would be useful for all developers involved if, at a glance, they knew whether that identifying parameter was a first, last, full name, or a ZIP/postal code instead of an ID.

You can use the FindByValue method to search the DropDownList for an Item with a Value matching the parameter.

dropdownlist.ClearSelection();
dropdownlist.Items.FindByValue(value).Selected = true;

Alternatively you can use the FindByText method to search the DropDownList for an Item with Text matching the parameter.

Before using the FindByValue method, don't forget to reset the DropDownList so that no items are selected by using the ClearSelection() method. It clears out the list selection and sets the Selected property of all items to false. Otherwise you will get the following exception.

"Cannot have multiple items selected in a DropDownList"

When we are dealing with time-series, calculating z-scores (or anomalies - not the same thing, but you can adapt this code easily) is a bit more complicated. For example, you have 10 years of temperature data measured weekly. To calculate z-scores for the whole time-series, you have to know the means and standard deviations for each day of the year. So, let's get started:

Assume you have a pandas DataFrame. First of all, you need a DateTime index. If you don't have it yet, but luckily you do have a column with dates, just make it as your index. Pandas will try to guess the date format. The goal here is to have DateTimeIndex. You can check it out by trying:

type(df.index)

If you don't have one, let's make it.

df.index = pd.DatetimeIndex(df[datecolumn])
df = df.drop(datecolumn,axis=1)

Next step is to calculate mean and standard deviation for each group of days. For this, we use the groupby method.

mean = pd.groupby(df,by=[df.index.dayofyear]).aggregate(np.nanmean)
std = pd.groupby(df,by=[df.index.dayofyear]).aggregate(np.nanstd)

Finally, we loop through all the dates, performing the calculation (value - mean)/stddev; however, as mentioned, for time-series this is not so straightforward.

df2 = df.copy() #keep a copy for future comparisons 
for y in np.unique(df.index.year):
    for d in np.unique(df.index.dayofyear):
        df2[(df.index.year==y) & (df.index.dayofyear==d)] = (df[(df.index.year==y) & (df.index.dayofyear==d)]- mean.ix[d])/std.ix[d]
        df2.index.name = 'date' #this is just to look nicer

df2 #this is your z-score dataset.

The logic inside the for loops is: for a given year we have to match each dayofyear to its mean and stdev. We run this for all the years in your time-series.

I just encountered the same problem myself.

... = reader["myYear"] as int?; works and is clean.

It works with any type without an issue. If the result is DBNull, it returns null as the conversion fails.

Your compiler just tried to compile the file named foo.cc. Upon hitting line number line, the compiler finds:

#include "bar"

or

#include <bar>

The compiler then tries to find that file. For this, it uses a set of directories to look into, but within this set, there is no file bar. For an explanation of the difference between the versions of the include statement look here.

How to tell the compiler where to find it

g++ has an option -I. It lets you add include search paths to the command line. Imagine that your file bar is in a folder named frobnicate, relative to foo.cc (assume you are compiling from the directory where foo.cc is located):

g++ -Ifrobnicate foo.cc

You can add more include-paths; each you give is relative to the current directory. Microsoft's compiler has a correlating option /I that works in the same way, or in Visual Studio, the folders can be set in the Property Pages of the Project, under Configuration Properties->C/C++->General->Additional Include Directories.

Now imagine you have multiple version of bar in different folders, given:

// A/bar
#include<string>
std::string which() { return "A/bar"; }

// B/bar
#include<string>
std::string which() { return "B/bar"; }

// C/bar
#include<string>
std::string which() { return "C/bar"; }

// foo.cc
#include "bar"
#include <iostream>

int main () {
    std::cout << which() << std::endl;
}

The priority with #include "bar" is leftmost:

$ g++ -IA -IB -IC foo.cc
$ ./a.out
A/bar

As you see, when the compiler started looking through A/, B/ and C/, it stopped at the first or leftmost hit.

This is true of both forms, include <> and incude "".

Difference between #include <bar> and #include "bar"

Usually, the #include <xxx> makes it look into system folders first, the #include "xxx" makes it look into the current or custom folders first.

E.g.:

Imagine you have the following files in your project folder:

list
main.cc

with main.cc:

#include "list"
....

For this, your compiler will #include the file list in your project folder, because it currently compiles main.cc and there is that file list in the current folder.

But with main.cc:

#include <list>
....

and then g++ main.cc, your compiler will look into the system folders first, and because <list> is a standard header, it will #include the file named list that comes with your C++ platform as part of the standard library.

This is all a bit simplified, but should give you the basic idea.

Details on <>/""-priorities and -I

According to the gcc-documentation, the priority for include <> is, on a "normal Unix system", as follows:

 /usr/local/include
 libdir/gcc/target/version/include
 /usr/target/include
 /usr/include

For C++ programs, it will also look in /usr/include/c++/version, first. In the above, target is the canonical name of the system GCC was configured to compile code for; [...].

The documentation also states:

You can add to this list with the -Idir command line option. All the directories named by -I are searched, in left-to-right order, before the default directories. The only exception is when dir is already searched by default. In this case, the option is ignored and the search order for system directories remains unchanged.

To continue our #include<list> / #include"list" example (same code):

g++ -I. main.cc

and

#include<list>
int main () { std::list<int> l; }

and indeed, the -I. prioritizes the folder . over the system includes and we get a compiler error.

The simplest way I was able to achieve a similar feat to use the code below (reference), but I would suggest not to make API calls in controllers(SOLID principles). Also autowiring this way is better optimsed than the traditional way of doing it.

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.web.client.RestTemplateBuilder;
import org.springframework.http.MediaType;
import org.springframework.web.bind.annotation.PathVariable;

    private final RestTemplate restTemplate;


    @Autowired
    public TestController(RestTemplateBuilder builder) {
        this.restTemplate = builder.build();
    }

    @RequestMapping(value="/micro/order/{id}", method= RequestMethod.GET, produces= MediaType.ALL_VALUE)
    public String placeOrder(@PathVariable("id") int customerId){

        System.out.println("Hit ===> PlaceOrder");

        Object[] customerJson = restTemplate.getForObject("http://localhost:8080/micro/customers", Object[].class);

        System.out.println(customerJson.toString());

        return "false";
    }
}

Visual Studio Community 2015 suffices to build extensions for Python 3.5. It's free but a 6 GB download (overkill). On my computer it installed vcvarsall at C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat

For Python 3.4 you'd need Visual Studio 2010. I don't think there's any free edition. See https://matthew-brett.github.io/pydagogue/python_msvc.html

I faced this issue a number of times in my application.

We can generally handle this with the below 2 approaches.

1. Pass the username and password in url itself

2. You can create an AutoIT Script and call script before opening the url.

Please check the below article in which I have mentioned both ways:
Handle Authentication/Login window in Selenium Webdriver

Consider the graph shown below with the source as Vertex A. First try running Dijkstra’s algorithm yourself on it.

When I refer to Dijkstra’s algorithm in my explanation I will be talking about the Dijkstra's Algorithm as implemented below,

So starting out the values (the distance from the source to the vertex) initially assigned to each vertex are,

We first extract the vertex in Q = [A,B,C] which has smallest value, i.e. A, after which Q = [B, C]. Note A has a directed edge to B and C, also both of them are in Q, therefore we update both of those values,

Now we extract C as (2<5), now Q = [B]. Note that C is connected to nothing, so line16 loop doesn't run.

Finally we extract B, after which . Note B has a directed edge to C but C isn't present in Q therefore we again don't enter the for loop in line16,

So we end up with the distances as

Note how this is wrong as the shortest distance from A to C is 5 + -10 = -5, when you go .

So for this graph Dijkstra's Algorithm wrongly computes the distance from A to C.

This happens because Dijkstra's Algorithm does not try to find a shorter path to vertices which are already extracted from Q.

What the line16 loop is doing is taking the vertex u and saying "hey looks like we can go to v from source via u, is that (alt or alternative) distance any better than the current dist[v] we got? If so lets update dist[v]"

Note that in line16 they check all neighbors v (i.e. a directed edge exists from u to v), of u which are still in Q. In line14 they remove visited notes from Q. So if x is a visited neighbour of u, the path is not even considered as a possible shorter way from source to v.

In our example above, C was a visited neighbour of B, thus the path was not considered, leaving the current shortest path unchanged.

This is actually useful if the edge weights are all positive numbers, because then we wouldn't waste our time considering paths that can't be shorter.

So I say that when running this algorithm if x is extracted from Q before y, then its not possible to find a path - which is shorter. Let me explain this with an example,

As y has just been extracted and x had been extracted before itself, then dist[y] > dist[x] because otherwise y would have been extracted before x. (line 13 min distance first)

And as we already assumed that the edge weights are positive, i.e. length(x,y)>0. So the alternative distance (alt) via y is always sure to be greater, i.e. dist[y] + length(x,y)> dist[x]. So the value of dist[x] would not have been updated even if y was considered as a path to x, thus we conclude that it makes sense to only consider neighbors of y which are still in Q (note comment in line16)

But this thing hinges on our assumption of positive edge length, if length(u,v)<0 then depending on how negative that edge is we might replace the dist[x] after the comparison in line18.

So any dist[x] calculation we make will be incorrect if x is removed before all vertices v - such that x is a neighbour of v with negative edge connecting them - is removed.

Because each of those v vertices is the second last vertex on a potential "better" path from source to x, which is discarded by Dijkstra’s algorithm.

So in the example I gave above, the mistake was because C was removed before B was removed. While that C was a neighbour of B with a negative edge!

Just to clarify, B and C are A's neighbours. B has a single neighbour C and C has no neighbours. length(a,b) is the edge length between the vertices a and b.

A pretty nice way to do this is to use SimpleDateFormat I'll show you how:

SimpleDateFormat sdf = new SimpleDateFormat("d MMMM YYYY");
Date d = new Date();
sdf.format(d);

I see that you have the date in a variable:

sdf.format(variable_name);

Cheers.

I think you can use db.collection.distinct(fields,query)

You will be able to get the distinct values in your case for NetworkID.

It should be something like this :

Db.collection.distinct('NetworkID')

The problem is at [System.Web.Services.WebMethod], add [WebMethod(EnableSession = false)] and you could get rid of page life cycle, by default EnableSession is true in Page and making page to come in life though life cycle events..

Please refer below page for more details http://msdn.microsoft.com/en-us/library/system.web.configuration.pagessection.enablesessionstate.aspx

There are multiple ways you can do this but I am not sure which one is the best practice. The first approach is you can append an iFrame in the dialog container on the fly with your given link:

$("#dialog").append($("<iframe />").attr("src", "your link")).dialog({dialogoptions});

Another would be to load the content of your external link into the dialog container using ajax.

$("#dialog").load("yourajaxhandleraddress.htm").dialog({dialogoptions});

Both works fine but depends on the external content.

It can't be done, either manually or progamatically. This is because the color behind every slide master is white. If you set your background to 100% transparent, it will print as white.

The best you could do is design your slide with all the stuff you want, group everything you want to appear in the transparent image and then right-click/save as picture/.PNG (or you could do that with a macro as well). In this way you would retain transparency.

Here's an example of how to export all slides' shapes to seperate PNG files. Note:

1. This does not get any background shapes on the Slide Master.
2. Resulting PNGs will not be the same size as each other, depending on where the shapes are located on each slide.

3. This uses a depreciated function, namely Shape.Export. This means that while the function is still available up to PowerPoint 2010, it may be removed from PowerPoint VBA later.

   Sub PrintShapesToPng()
       Dim ap As Presentation: Set ap = ActivePresentation
       Dim sl As slide
       Dim shGroup As ShapeRange
       For Each sl In ap.Slides
           ActiveWindow.View.GotoSlide (sl.SlideIndex)
           sl.Shapes.SelectAll
           Set shGroup = ActiveWindow.Selection.ShapeRange
           shGroup.Export ap.Path & "\Slide" & sl.SlideIndex & ".png", _
                               ppShapeFormatPNG, , , ppRelativeToSlide
       Next
   End Sub
   

I had the same problem. Wound up just writing a custom highlight and unhighlight function for the validator. Adding this to the validaton options should add the error class to the element and its respective label:

        'highlight': function (element, errorClass, validClass) {
            if($(element).attr('type') == 'radio'){
                $(element.form).find("input[type=radio]").each(function(which){
                    $(element.form).find("label[for=" + this.id + "]").addClass(errorClass);
                    $(this).addClass(errorClass);
                });
            } else {
                $(element.form).find("label[for=" + element.id + "]").addClass(errorClass);
                $(element).addClass(errorClass);
            }
        },
        'unhighlight': function (element, errorClass, validClass) {
            if($(element).attr('type') == 'radio'){
                $(element.form).find("input[type=radio]").each(function(which){
                    $(element.form).find("label[for=" + this.id + "]").removeClass(errorClass);
                    $(this).removeClass(errorClass);
                });
            }else {
                $(element.form).find("label[for=" + element.id + "]").removeClass(errorClass);
                $(element).removeClass(errorClass);
            }
        },

You can give to_s a base other than 10:

10.to_s(16)  #=> "a"

Note that in ruby 2.4 FixNum and BigNum were unified in the Integer class. If you are using an older ruby check the documentation of FixNum#to_s and BigNum#to_s

You could query an LDAP server from the command line with ldap-utils: ldapsearch, ldapadd, ldapmodify

Instead of Windows PowerShell, find the item in the Start Menu called SharePoint 2013 Management Shell:

use:

routes.MapHttpRoute(
    name: "DefaultApi",
    routeTemplate: "api/{controller}/{action}/{id}",
    defaults: new { id = RouteParameter.Optional }
);

it's not a RESTful approach anymore, but you can now call your actions by name (rather than let the Web API automatically determine one for you based on the verb) like this:

[POST] /api/VTRouting/TSPRoute

[POST] /api/VTRouting/Route

Contrary to popular belief, there is nothing wrong with this approach, and it's not abusing Web API. You can still leverage on all the awesome features of Web API (delegating handlers, content negotiation, mediatypeformatters and so on) - you just ditch the RESTful approach.

Consider using

.scrollIntoView()

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

As I wrote in the edits of the op, to edit existing excel documents you must use the xlutils module (Thanks Oliver)

Here is the proper way to do it:

#xlrd, xlutils and xlwt modules need to be installed.  
#Can be done via pip install <module>
from xlrd import open_workbook
from xlutils.copy import copy

rb = open_workbook("names.xls")
wb = copy(rb)

s = wb.get_sheet(0)
s.write(0,0,'A1')
wb.save('names.xls')

This replaces the contents of the cell located at a1 in the first sheet of "names.xls" with the text "a1", and then saves the document.

simple synchronous way with node:

let fs = require('fs')

let filename = "your-file.something"

let content = fs.readFileSync(process.cwd() + "/" + filename).toString()

console.log(content)

Given the code you provided in comments, I assume you want to do this:

>>> dateList = "Thu Sep 16 13:14:15 CDT 2010".split()
>>> sdateList = "Thu Sep 16 14:14:15 CDT 2010".split()
>>> dateList == sdataList
false

The split-method of the string returns a list. A list in Python is very different from an array. == in this case does an element-wise comparison of the two lists and returns if all their elements are equal and the number and order of the elements is the same. Read the documentation.

You're currently trying to remove the exact string [] - two square brackets with nothing between them. Instead, you want to remove all [ and separately remove all ].

Personally I would avoid using replaceAll here as it introduces more confusion due to the regex part - I'd use:

String replaced = original.replace("[", "").replace("]", "");

Only use the methods which take regular expressions if you really want to do full pattern matching. When you just want to replace all occurrences of a fixed string, replace is simpler to read and understand.

(There are alternative approaches which use the regular expression form and really match patterns, but I think the above code is significantly simpler.)

If you see the man page of logger:

$ man logger

LOGGER(1) BSD General Commands Manual LOGGER(1)

NAME logger — a shell command interface to the syslog(3) system log module

SYNOPSIS logger [-isd] [-f file] [-p pri] [-t tag] [-u socket] [message ...]

DESCRIPTION Logger makes entries in the system log. It provides a shell command interface to the syslog(3) system log module.

It Clearly says that it will log to system log. If you want to log to file, you can use ">>" to redirect to log file.

It is possible to insert an image in a Google Spreadsheet using Google Apps Script. However, the image should have been hosted publicly over internet. At present, it is not possible to insert private images from Google Drive.

You can use following code to insert an image through script.

  function insertImageOnSpreadsheet() {
  var SPREADSHEET_URL = 'INSERT_SPREADSHEET_URL_HERE';
  // Name of the specific sheet in the spreadsheet.
  var SHEET_NAME = 'INSERT_SHEET_NAME_HERE';

  var ss = SpreadsheetApp.openByUrl(SPREADSHEET_URL);
  var sheet = ss.getSheetByName(SHEET_NAME);

  var response = UrlFetchApp.fetch(
      'https://developers.google.com/adwords/scripts/images/reports.png');
  var binaryData = response.getContent();

  // Insert the image in cell A1.
  var blob = Utilities.newBlob(binaryData, 'image/png', 'MyImageName');
  sheet.insertImage(blob, 1, 1);
}

Above example has been copied from this link. Check noogui's reply for details.

In case you need to insert image from Google Drive, please check this link for current updates.

Stack trace is prserved if you wrap the catched excetion into an other exception (to provide more info) or if you just rethrow the catched excetion.

try{ ... }catch (FooException e){ throw new BarException("Some usefull info", e); }

null is a special value that is not an instance of any class. This is illustrated by the following program:

public class X {
   void f(Object o)
   { 
      System.out.println(o instanceof String);   // Output is "false"
   }
   public static void main(String[] args) {
      new X().f(null);
   }
}

Yes it works fine and is commonly used:

$ echo "hello world" | mail -s "a subject" [email protected]

After invalidating Cache, changing from

import android.support.v7.app.AppCompatActivity;

to

import androidx.appcompat.app.AppCompatActivity;

worked for me.

adb logcat -c

Logcat options are documented here: http://developer.android.com/tools/help/logcat.html

for x in y[:-1]

If y is a generator, then the above will not work.

There's no need for you to use super-call of the ActionBarDrawerToggle which requires the Toolbar. This means instead of using the following constructor:

ActionBarDrawerToggle(Activity activity, DrawerLayout drawerLayout, Toolbar toolbar, int openDrawerContentDescRes, int closeDrawerContentDescRes)

You should use this one:

ActionBarDrawerToggle(Activity activity, DrawerLayout drawerLayout, int openDrawerContentDescRes, int closeDrawerContentDescRes)

So basically the only thing you have to do is to remove your custom drawable:

super(mActivity, mDrawerLayout, R.string.ns_menu_open, R.string.ns_menu_close);

More about the "new" ActionBarDrawerToggle in the Docs (click).

With RestAssurd you can also do the following:

String path = baseApiUrl; //This is the base url of the API tested
    URL url = new URL(path);
    given(). //Rest Assured syntax 
            contentType("application/json"). //API content type
            given().header("headerName", "headerValue"). //Some API contains headers to run with the API 
            when().
            get(url).
            then().
            statusCode(200); //Assert that the response is 200 - OK

First all answers are right, you can pass the data except custom objects by using Intent. If you want to pass the custom objects, you have to implement Serialazable or Parcelable to your custom object class. I thought it's too much complicated...

So if your project is simple, try to use DataCache. That provides super simple way for passing data. Ref: Github project CachePot

1- Set this to View or Activity or Fragment which will send data

DataCache.getInstance().push(obj);

2- Get data anywhere like below

public class MainFragment extends Fragment
{
    private YourObject obj;

    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);

        obj = DataCache.getInstance().pop(YourObject.class);

    }//end onCreate()
}//end class MainFragment

 var marker+i = "some stuff";

coudl be interpreted like this: create a variable named marker (undefined); then add to i; then try to assign a value to to the result of an expression, not possible. What firebug is saying is this: var marker; i = 'some stuff'; this is what firebug expects a comma after marker and before i; var is a statement and don't (apparently) accepts expressions. Not so good an explanation but i hope it helps.

$(document).ready(function() {
  $('#btnSun').click(function(){

      myFunction();

   });

   $.fn.myFunction = function() { 
     alert('hi'); 

    }; 
});

Put ' ; ' after function definition...

An alternative that also has the added benefit of easily logging its output:

hexs = "13 00 00 00 08 00"
logging.debug(hexs)
key = bytearray.fromhex(hexs)

allows you to do easy substitutions like so:

hexs = "13 00 00 00 08 {:02X}".format(someByte)
logging.debug(hexs)
key = bytearray.fromhex(hexs)

From JavaEE docs ServletResponse#setContentType

• Sets the content type of the response being sent to the client, if the response has not been committed yet.

• The given content type may include a character encoding specification, for example,

response.setContentType("text/html;charset=UTF-8");

• The response's character encoding is only set from the given content type if this method is called before getWriter is called.

• This method may be called repeatedly to change content type and character encoding.

• This method has no effect if called after the response has been committed. It does not set the response's character encoding if it is called after getWriter has been called or after the response has been committed.

• Containers must communicate the content type and the character encoding used for the servlet response's writer to the client if the protocol provides a way for doing so. In the case of HTTP, the Content-Type header is used.

The chosen answer looks like does not apply to modern browsers, at least on Firefox 52. What I observed is that the requests of loading resources like css, javascript are issued before HTML parser reaches the element, for example

<html>
  <head>
    <!-- prints the date before parsing and blocks HTMP parsering -->
    <script>
      console.log("start: " + (new Date()).toISOString());
      for(var i=0; i<1000000000; i++) {};
    </script>

    <script src="jquery.js" type="text/javascript"></script>
    <script src="abc.js" type="text/javascript"></script>
    <link rel="stylesheets" type="text/css" href="abc.css"></link>
    <style>h2{font-wight:bold;}</style>
    <script>
      $(document).ready(function(){
      $("#img").attr("src", "kkk.png");
     });
   </script>
 </head>
 <body>
   <img id="img" src="abc.jpg" style="width:400px;height:300px;"/>
   <script src="kkk.js" type="text/javascript"></script>
   </body>
</html>

What I found that the start time of requests to load css and javascript resources were not being blocked. Looks like Firefox has a HTML scan, and identify key resources(img resource is not included) before starting to parse the HTML.

General

Single elements of a tuple a can be accessed -in an indexed array-like fashion-

via a[0], a[1], ... depending on the number of elements in the tuple.

Example

If your tuple is a=(3,"a")

• a[0] yields 3,
• a[1] yields "a"

Concrete answer to question

def tup():
  return (3, "hello")

tup() returns a 2-tuple.

In order to "solve"

i = 5 + tup()  # I want to add just the three

you select the 3 by

tup()[0|    #first element

so in total

i = 5 + tup()[0]

Alternatives

Go with namedtuple that allows you to access tuple elements by name (and by index). Details at https://docs.python.org/3/library/collections.html#collections.namedtuple

>>> import collections
>>> MyTuple=collections.namedtuple("MyTuple", "mynumber, mystring")
>>> m = MyTuple(3, "hello")
>>> m[0]
3
>>> m.mynumber
3
>>> m[1]
'hello'
>>> m.mystring
'hello'

I tested below code with SQL Server 2008 R2 Express and I believe we should have solution for all 6 steps you outlined. Let's take on them one-by-one:

1 - Enable TCP/IP

We can enable TCP/IP protocol with WMI:

set wmiComputer = GetObject( _
    "winmgmts:" _
    & "\\.\root\Microsoft\SqlServer\ComputerManagement10")
set tcpProtocols = wmiComputer.ExecQuery( _
    "select * from ServerNetworkProtocol " _
    & "where InstanceName = 'SQLEXPRESS' and ProtocolName = 'Tcp'")

if tcpProtocols.Count = 1 then
    ' set tcpProtocol = tcpProtocols(0)
    ' I wish this worked, but unfortunately 
    ' there's no int-indexed Item property in this type

    ' Doing this instead
    for each tcpProtocol in tcpProtocols
        dim setEnableResult
            setEnableResult = tcpProtocol.SetEnable()
            if setEnableResult <> 0 then 
                Wscript.Echo "Failed!"
            end if
    next
end if

2 - Open the right ports in the firewall

I believe your solution will work, just make sure you specify the right port. I suggest we pick a different port than 1433 and make it a static port SQL Server Express will be listening on. I will be using 3456 in this post, but please pick a different number in the real implementation (I feel that we will see a lot of applications using 3456 soon :-)

3 - Modify TCP/IP properties enable a IP address

We can use WMI again. Since we are using static port 3456, we just need to update two properties in IPAll section: disable dynamic ports and set the listening port to 3456:

set wmiComputer = GetObject( _
    "winmgmts:" _
    & "\\.\root\Microsoft\SqlServer\ComputerManagement10")
set tcpProperties = wmiComputer.ExecQuery( _
    "select * from ServerNetworkProtocolProperty " _
    & "where InstanceName='SQLEXPRESS' and " _
    & "ProtocolName='Tcp' and IPAddressName='IPAll'")

for each tcpProperty in tcpProperties
    dim setValueResult, requestedValue

    if tcpProperty.PropertyName = "TcpPort" then
        requestedValue = "3456"
    elseif tcpProperty.PropertyName ="TcpDynamicPorts" then
        requestedValue = ""
    end if

    setValueResult = tcpProperty.SetStringValue(requestedValue)
    if setValueResult = 0 then 
        Wscript.Echo "" & tcpProperty.PropertyName & " set."
    else
        Wscript.Echo "" & tcpProperty.PropertyName & " failed!"
    end if
next

Note that I didn't have to enable any of the individual addresses to make it work, but if it is required in your case, you should be able to extend this script easily to do so.

Just a reminder that when working with WMI, WBEMTest.exe is your best friend!

4 - Enable mixed mode authentication in sql server

I wish we could use WMI again, but unfortunately this setting is not exposed through WMI. There are two other options:

1. Use LoginMode property of Microsoft.SqlServer.Management.Smo.Server class, as described here.

2. Use LoginMode value in SQL Server registry, as described in this post. Note that by default the SQL Server Express instance is named SQLEXPRESS, so for my SQL Server 2008 R2 Express instance the right registry key was HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL10_50.SQLEXPRESS\MSSQLServer.

5 - Change user (sa) default password

You got this one covered.

6 - Finally (connect to the instance)

Since we are using a static port assigned to our SQL Server Express instance, there's no need to use instance name in the server address anymore.

SQLCMD -U sa -P newPassword -S 192.168.0.120,3456

Please let me know if this works for you (fingers crossed!).

you can try this

td.setAttribute("style", "font-weight:bold");

In Ef .net core there are two options that you can do; first with data annotations:

public class Blog
{
    public int BlogId { get; set; }
    [Required]
    public string Url { get; set; }
}

Or with fluent api:

class MyContext : DbContext
{
    public DbSet<Blog> Blogs { get; set; }

    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        modelBuilder.Entity<Blog>()
            .Property(b => b.Url)
            .IsRequired(false)//optinal case
            .IsRequired()//required case
            ;
    }
}

public class Blog
{
    public int BlogId { get; set; }
    public string Url { get; set; }
}

simple......in the html file right....have the "footer" (or the div you want at the bottom) at the bottom. So dont do this:

<div id="container">
    <div id="Header"></div>
    <div id="Footer"></div>
    <div id="Content"></div>
    <div id="Sidebar"></div>
</div>

DO THIS: (have the footer underneath.)

<div id="container">
    <div id="Header"></div>
    <div id="Content"></div>
    <div id="Sidebar"></div>
    <div id="Footer"></div>
</div>

After doing this then you can go the css file and have the "sidebar" float to the left. then have "content" float to the right then have "footer" clear both.

that should work.did for me.

If you want to call these methods without including module in another class then you need to define them as module methods:

module UsefulThings
  def self.get_file; ...
  def self.delete_file; ...

  def self.format_text(x); ...
end

and then you can call them with

UsefulThings.format_text("xxx")

or

UsefulThings::format_text("xxx")

But anyway I would recommend that you put just related methods in one module or in one class. If you have problem that you want to include just one method from module then it sounds like a bad code smell and it is not good Ruby style to put unrelated methods together.

Use _.map instead of _.pluck. In the latest version the _.pluck has been removed.

bool = !bool;

This holds true in most languages.

For hibernate it is important to know that your object WILL have an id, when you want to persist/save it. Thus, make sure that

    private String U_id;

will have a value, by the time you are going to persist your object. You can do that with the @GeneratedValue annotation or by assigning a value manually.

In the case you need or want to assign your id's manually (and that's what the above error is actually about), I would prefer passing the values for the fields to your constructor, at least for U_id, e.g.

  public Role (String U_id) { ... }

This ensures that your object has an id, by the time you have instantiated it. I don't know what your use case is and how your application behaves in concurrency, however, in some cases this is not recommended. You need to ensure that your id is unique.

Further note: Hibernate will still require a default constructor, as stated in the hibernate documentation. In order to prevent you (and maybe other programmers if you're designing an api) of instantiations of Role using the default constructor, just declare it as private.

just had the same problem, however this was the simplest solution:

<?php (date('Y')+1).date('-m-d'); ?>

This function takes the difference between two dates and shows it in a date format yyyy-mm-dd. All you need is to execute the code below and then use the function. After executing you can use it like this

SELECT datedifference(date1, date2)
FROM ....

You have to do two things before a submodule will be filled:

git submodule init 
git submodule update

Other way to combine features and target variables can be using np.column_stack (details)

import numpy as np
import pandas as pd
from sklearn.datasets import load_iris

data = load_iris()
df = pd.DataFrame(np.column_stack((data.data, data.target)), columns = data.feature_names+['target'])
print(df.head())

Result:

   sepal length (cm)  sepal width (cm)  petal length (cm)  petal width (cm)     target
0                5.1               3.5                1.4               0.2     0.0
1                4.9               3.0                1.4               0.2     0.0 
2                4.7               3.2                1.3               0.2     0.0 
3                4.6               3.1                1.5               0.2     0.0
4                5.0               3.6                1.4               0.2     0.0

If you need the string label for the target, then you can use replace by convertingtarget_names to dictionary and add a new column:

df['label'] = df.target.replace(dict(enumerate(data.target_names)))
print(df.head())

Result:

   sepal length (cm)  sepal width (cm)  petal length (cm)  petal width (cm)     target  label 
0                5.1               3.5                1.4               0.2     0.0     setosa

2                4.7               3.2                1.3               0.2     0.0     setosa

@RequestMapping(value = "/testonly", method = { RequestMethod.GET, RequestMethod.POST })
public ModelAndView listBooksPOST(@ModelAttribute("booksFilter") BooksFilter filter,
        @RequestParam(required = false) String parameter1,
        @RequestParam(required = false) String parameter2, 
        BindingResult result, HttpServletRequest request) 
        throws ParseException {

    LONG CODE and SAME LONG CODE with a minor difference
}

if @RequestParam(required = true) then you must pass parameter1,parameter2

Use BindingResult and request them based on your conditions.

The Other way

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

    myMethod();

}


@RequestMapping(value = "/books", method = RequestMethod.POST)
public ModelAndView listBooksPOST(@ModelAttribute("booksFilter") BooksFilter filter, 
        BindingResult result) throws ParseException {

    myMethod();

    do here your minor difference
}

private returntype myMethod(){
    LONG CODE
}

Since there is so much confusion about functionality of standard service accounts, I'll try to give a quick run down.

First the actual accounts:

• LocalService account (preferred)

  A limited service account that is very similar to Network Service and meant to run standard least-privileged services. However, unlike Network Service it accesses the network as an Anonymous user.

  • Name: NT AUTHORITY\LocalService
  • the account has no password (any password information you provide is ignored)
  • HKCU represents the LocalService user account
  • has minimal privileges on the local computer
  • presents anonymous credentials on the network
  • SID: S-1-5-19
  • has its own profile under the HKEY_USERS registry key (HKEY_USERS\S-1-5-19)

   

• NetworkService account

  Limited service account that is meant to run standard privileged services. This account is far more limited than Local System (or even Administrator) but still has the right to access the network as the machine (see caveat above).

  • NT AUTHORITY\NetworkService
  • the account has no password (any password information you provide is ignored)
  • HKCU represents the NetworkService user account
  • has minimal privileges on the local computer
  • presents the computer's credentials (e.g. MANGO$) to remote servers
  • SID: S-1-5-20
  • has its own profile under the HKEY_USERS registry key (HKEY_USERS\S-1-5-20)
  • If trying to schedule a task using it, enter NETWORK SERVICE into the Select User or Group dialog

   

• LocalSystem account (dangerous, don't use!)

  Completely trusted account, more so than the administrator account. There is nothing on a single box that this account cannot do, and it has the right to access the network as the machine (this requires Active Directory and granting the machine account permissions to something)

  • Name: .\LocalSystem (can also use LocalSystem or ComputerName\LocalSystem)
  • the account has no password (any password information you provide is ignored)
  • SID: S-1-5-18
  • does not have any profile of its own (HKCU represents the default user)
  • has extensive privileges on the local computer
  • presents the computer's credentials (e.g. MANGO$) to remote servers

   

Above when talking about accessing the network, this refers solely to SPNEGO (Negotiate), NTLM and Kerberos and not to any other authentication mechanism. For example, processing running as LocalService can still access the internet.

The general issue with running as a standard out of the box account is that if you modify any of the default permissions you're expanding the set of things everything running as that account can do. So if you grant DBO to a database, not only can your service running as Local Service or Network Service access that database but everything else running as those accounts can too. If every developer does this the computer will have a service account that has permissions to do practically anything (more specifically the superset of all of the different additional privileges granted to that account).

It is always preferable from a security perspective to run as your own service account that has precisely the permissions you need to do what your service does and nothing else. However, the cost of this approach is setting up your service account, and managing the password. It's a balancing act that each application needs to manage.

In your specific case, the issue that you are probably seeing is that the the DCOM or COM+ activation is limited to a given set of accounts. In Windows XP SP2, Windows Server 2003, and above the Activation permission was restricted significantly. You should use the Component Services MMC snapin to examine your specific COM object and see the activation permissions. If you're not accessing anything on the network as the machine account you should seriously consider using Local Service (not Local System which is basically the operating system).

In Windows Server 2003 you cannot run a scheduled task as

• NT_AUTHORITY\LocalService (aka the Local Service account), or
• NT AUTHORITY\NetworkService (aka the Network Service account).

That capability only was added with Task Scheduler 2.0, which only exists in Windows Vista/Windows Server 2008 and newer.

A service running as NetworkService presents the machine credentials on the network. This means that if your computer was called mango, it would present as the machine account MANGO$:

What should I do to prepare my website for https. (Do I need to alter the code / Config)

You should keep best practices for secure coding in mind (here is a good intro: http://www.owasp.org/index.php/Secure_Coding_Principles ), otherwise all you need is a correctly set up SSL certificate.

Is SSL and https one and the same..

Pretty much, yes.

Do I need to apply with someone to get some license or something.

You can buy an SSL certificate from a certificate authority or use a self-signed certificate. The ones you can purchase vary wildly in price - from $10 to hundreds of dollars a year. You would need one of those if you set up an online shop, for example. Self-signed certificates are a viable option for an internal application. You can also use one of those for development. Here's a good tutorial on how to set up a self-signed certificate for IIS: Enabling SSL on IIS 7.0 Using Self-Signed Certificates

Do I need to make all my pages secured or only the login page..

Use HTTPS for everything, not just the initial user login. It's not going to be too much of an overhead and it will mean the data that the users send/receive from your remotely hosted application cannot be read by outside parties if it is intercepted. Even Gmail now turns on HTTPS by default.

UPDATE
From v0.20, melt is a first order function, you can now use

df.melt(id_vars=["location", "name"], 
        var_name="Date", 
        value_name="Value")

  location    name        Date  Value
0        A  "test"    Jan-2010     12
1        B   "foo"    Jan-2010     18
2        A  "test"    Feb-2010     20
3        B   "foo"    Feb-2010     20
4        A  "test"  March-2010     30
5        B   "foo"  March-2010     25

OLD(ER) VERSIONS: <0.20

You can use pd.melt to get most of the way there, and then sort:

>>> df
  location  name  Jan-2010  Feb-2010  March-2010
0        A  test        12        20          30
1        B   foo        18        20          25
>>> df2 = pd.melt(df, id_vars=["location", "name"], 
                  var_name="Date", value_name="Value")
>>> df2
  location  name        Date  Value
0        A  test    Jan-2010     12
1        B   foo    Jan-2010     18
2        A  test    Feb-2010     20
3        B   foo    Feb-2010     20
4        A  test  March-2010     30
5        B   foo  March-2010     25
>>> df2 = df2.sort(["location", "name"])
>>> df2
  location  name        Date  Value
0        A  test    Jan-2010     12
2        A  test    Feb-2010     20
4        A  test  March-2010     30
1        B   foo    Jan-2010     18
3        B   foo    Feb-2010     20
5        B   foo  March-2010     25

(Might want to throw in a .reset_index(drop=True), just to keep the output clean.)

Note: pd.DataFrame.sort has been deprecated in favour of pd.DataFrame.sort_values.

rownumber() over(...) is working but I didn't like this solution for 2 reasons. - This function is not available when you using older version of SQL like SQL2000 - Dependency on function and is not really readable.

Another solution is:

       tmpall.[PartCode] ,
       tmpall.[Quantity] ,
FROM   (SELECT [OrderNO],
               [PartCode],
               [Quantity],
               [DateEntered]
        FROM   you_table) AS tmpall
       INNER JOIN (SELECT [OrderNO],
                          Max([DateEntered]) AS _max_date
                   FROM   your_table
                   GROUP  BY OrderNO ) AS tmplast
               ON tmpall.[OrderNO] = tmplast.[OrderNO]
                  AND tmpall.[DateEntered] = tmplast._max_date

You should use :first-child instead of :first:

Sounds like you're wanting to iterate through them. You can do this using .each().

Example:

$('td:first-child').each(function() {
    console.log($(this).text());
});

Result:

nonono
nonono2
nonono3

Alernatively if you're not wanting to iterate:

$('td:first-child').css('background', '#000');

JSFiddle demo.

Suppose you have a big project written in c++ which has a thousand of .cpp files and a thousand of .h files.And let's says the project also depends on ten static libraries. Let's says we are on Windows and we build our project in Visual Studio 20xx. When you press Ctrl + F7 Visual Studio to start compiling the whole solution ( suppose we have just one project in the solution )

What's the meaning of compilation ?

• Visual Studio search into file .vcxproj and start compiling each file which has the extension .cpp. Order of compilation is undefined.So you must not assume that the file main.cpp is compiled first
• If .cpp files depends on additional .h files in order to find symbols that may or may not be defined in the file .cpp
• If exists one .cpp file in which the compiler could not find one symbol, a compiler time error raises the message Symbol x could not be found
• For each file with extension .cpp is generated an object file .o and also Visual Studio writes the output in a file named ProjectName.Cpp.Clean.txt which contains all object files that must be processed by the linker.

The Second step of compilation is done by Linker.Linker should merge all the object file and build finally the output ( which may be an executable or a library)

Steps In Linking a project

• Parse all the object files and find the definition which was only declared in headers ( eg: The code of one method of a class as is mentioned in previous answers, or event the initialization of a static variable which is member inside a class)
• If one symbol could not be found in object files he also is searched in Additional Libraries.For adding a new library to a project Configuration properties -> VC++ Directories -> Library Directories and here you specified additional folder for searching libraries and Configuration properties -> Linker -> Input for specifying the name of the library. -If the Linker could not find the symbol which you write in one .cpp he raises a linker time error which may sound like error LNK2001: unresolved external symbol "void __cdecl foo(void)" (?foo@@YAXXZ)

Observation

1. Once the Linker find one symbol he doesn't search in other libraries for it
2. The order of linking libraries does matter.
3. If Linker finds an external symbol in one static library he includes the symbol in the output of the project.However, if the library is shared( dynamic ) he doesn't include the code ( symbols ) in output, but Run-Time crashes may occur

How To Solve this kind of error

Compiler Time Error :

• Make sure you write your c++ project syntactical correct.

Linker Time Error

• Define all your symbol which you declare in your header files
• Use #pragma once for allowing compiler not to include one header if it was already included in the current .cpp which are compiled
• Make sure that your external library doesn't contain symbols that may enter into conflict with other symbols you defined in your header files
• When you use the template to make sure you include the definition of each template function in the header file for allowing the compiler to generate appropriate code for any instantiations.

Best explanation for X = aY + b (in fact it f(x) = ax + b)) is provided at https://math.stackexchange.com/a/906280/357701

A Simpler one by just adjusting lightness/luma/brightness for contrast as is below:

import cv2

img = cv2.imread('test.jpg')
cv2.imshow('test', img)
cv2.waitKey(1000)
imghsv = cv2.cvtColor(img, cv2.COLOR_BGR2HSV)


imghsv[:,:,2] = [[max(pixel - 25, 0) if pixel < 190 else min(pixel + 25, 255) for pixel in row] for row in imghsv[:,:,2]]
cv2.imshow('contrast', cv2.cvtColor(imghsv, cv2.COLOR_HSV2BGR))
cv2.waitKey(1000)
raw_input()

If using 3rd Pary Libaries is ok cyclops-react defines Lazy extended collections with this functionality built in. For example we could simply write

ListX myListToParse;

ListX myFinalList = myListToParse.filter(elt -> elt != null) .map(elt -> doSomething(elt));

myFinalList is not evaluated until first access (and there after the materialized list is cached and reused).

[Disclosure I am the lead developer of cyclops-react]

function hexToStr($hex){
    // Remove spaces if the hex string has spaces
    $hex = str_replace(' ', '', $hex);
    return hex2bin($hex);
}
// Test it 
$hex    = "53 44 43 30 30 32 30 30 30 31 37 33";
echo hexToStr($hex); // SDC002000173

/**
 * Test Hex To string with PHP UNIT
 * @param  string $value
 * @return 
 */
public function testHexToString()
{
    $string = 'SDC002000173';
    $hex    = "53 44 43 30 30 32 30 30 30 31 37 33";
    $result = hexToStr($hex);

    $this->assertEquals($result,$string);
}

I know this question was asked 2 years ago, but I run into the same issue and the answer for the problem is since ES2017, that you can simply await the functions return value (as of now, only works in async functions), like:

let AuthUser = function(data) {
  return google.login(data.username, data.password).then(token => { return token } )
}

let userToken = await AuthUser(data)
console.log(userToken) // your data

The length of an array is available as

int l = array.length;

The size of a List is availabe as

int s = list.size();

    // A generic test function that can be configured 
    // with an arbitrary delay and to either resolve or reject
    const test = (delay, resolveSuccessfully) => new Promise((resolve, reject) => setTimeout(() => {
        console.log(`Done ${ delay }`);
        resolveSuccessfully ? resolve(`Resolved ${ delay }`) : reject(`Reject ${ delay }`)
    }, delay));

    // Our async handler function
    const handler = async () => {
        // Promise 1 runs first, but resolves last
        const p1 = test(10000, true);
        // Promise 2 run second, and also resolves
        const p2 = test(5000, true);
        // Promise 3 runs last, but completes first (with a rejection) 
        // Note the catch to trap the error immediately
        const p3 = test(1000, false).catch(e => console.log(e));
        // Await all in parallel
        const r = await Promise.all([p1, p2, p3]);
        // Display the results
        console.log(r);
    };

    // Run the handler
    handler();
    /*
    Done 1000
    Reject 1000
    Done 5000
    Done 10000
    */

Whilst setting p1, p2 and p3 is not strictly running them in parallel, they do not hold up any execution and you can trap contextual errors with a catch.

Datalist includes autocomplete and suggestions natively, it can also allow a user to enter a value that is not defined in the suggestions.

Select only gives you pre-defined options the user has to select from

Just to clarify my comment (it's illegible in a single line)

I think the best answer is the comment by Mike Chambers in this link (http://www.judahfrangipane.com/blog/2007/02/15/error-2032-stream-error/) by Hunter McMillen.

A note from Mike Chambers:

If you run into this using URLLoader, listen for the:

flash.events.HTTPStatusEvent.HTTP_STATUS

and in AIR :

flash.events.HTTPStatusEvent.HTTP_RESPONSE_STATUS

It should give you some more information (such as the status code being returned from the server).

del statement does not delete an instance, it merely deletes a name.

When you do del i, you are deleting just the name i - but the instance is still bound to some other name, so it won't be Garbage-Collected.

If you want to release memory, your dataframes has to be Garbage-Collected, i.e. delete all references to them.

If you created your dateframes dynamically to list, then removing that list will trigger Garbage Collection.

>>> lst = [pd.DataFrame(), pd.DataFrame(), pd.DataFrame()]
>>> del lst     # memory is released

If you created some variables, you have to delete them all.

>>> a, b, c = pd.DataFrame(), pd.DataFrame(), pd.DataFrame()
>>> lst = [a, b, c]
>>> del a, b, c # dfs still in list
>>> del lst     # memory release now

To add class to a element

document.querySelector(elem).className+=' first second third';

UPDATE:

Remove a class

document.querySelector(elem).className=document.querySelector(elem).className.split(class_to_be_removed).join(" ");

hash_map was a common extension provided by many library implementations. That is exactly why it was renamed to unordered_map when it was added to the C++ standard as part of TR1. map is generally implemented with a balanced binary tree like a red-black tree (implementations vary of course). hash_map and unordered_map are generally implemented with hash tables. Thus the order is not maintained. unordered_map insert/delete/query will be O(1) (constant time) where map will be O(log n) where n is the number of items in the data structure. So unordered_map is faster, and if you don't care about the order of the items should be preferred over map. Sometimes you want to maintain order (ordered by the key) and for that map would be the choice.

Simply performing some arithmetic on a Date object will return the timestamp as a number. This is useful for compact notation. I find this is the easiest way to remember, as the method also works for converting numbers cast as string types back to number types.

let d = new Date();
console.log(d, d * 1);

file = open("myfile.txt", "r")
lines = file.readlines()
str = ''                                     #string declaration

for i in range(len(lines)):
    str += lines[i].rstrip('\n') + ' '

print str

This is a one line solution involving LINQ.

var elements = new String[] { "1", "2", "3" };
Foo(elements.Cast<object>().ToArray())

You can float the elements (the map wrapper, and the paragraph), or use inline-block on both of them.

Copied from http://exampledepot.8waytrips.com/egs/java.io/RenameFile.html

// File (or directory) with old name
File file = new File("oldname");

// File (or directory) with new name
File file2 = new File("newname");

if (file2.exists())
   throw new java.io.IOException("file exists");

// Rename file (or directory)
boolean success = file.renameTo(file2);

if (!success) {
   // File was not successfully renamed
}

To append to the new file:

java.io.FileWriter out= new java.io.FileWriter(file2, true /*append=yes*/);

Following Worked for me for scikit-learn on Anaconda-Jupyter Notebook.

Upgrading my scikit-learn from 0.19.1 to 0.19.2 in anaconda installed on Ubuntu on Google VM instance:

Run the following commands in the terminal:

First, check existing available packages with versions by using:

conda list    

It will show different packages and their installed versions in the output. Here check for scikit-learn. e.g. for me, the output was:

scikit-learn              0.19.1           py36hedc7406_0  

Now I want to Upgrade to 0.19.2 July 2018 release i.e. latest available version.

conda config --append channels conda-forge
conda install scikit-learn=0.19.2

As you are trying to upgrade to 0.17 version try the following command:

conda install scikit-learn=0.17

Now check the required version of the scikit-learn is installed correctly or not by using:

conda list 

For me the Output was:

scikit-learn              0.19.2          py36_blas_openblasha84fab4_201  [blas_openblas]  conda-forge

Note: Don't use pip command if you are using Anaconda or Miniconda

I tried following commands:

!conda update conda 
!pip install -U scikit-learn

It will install the required packages also will show in the conda list but if you try to import that package it will not work.

On the website http://scikit-learn.org/stable/install.html it is mentioned as: Warning To upgrade or uninstall scikit-learn installed with Anaconda or conda you should not use the pip.

You can use dir(your_object) to get the attributes and getattr(your_object, your_object_attr) to get the values

usage :

for att in dir(your_object):
    print (att, getattr(your_object,att))

This is a barebones look at what I've done to float one image over another.

img {_x000D_
  position: absolute;_x000D_
  top: 25px;_x000D_
  left: 25px;_x000D_
}_x000D_
.imgA1 {_x000D_
  z-index: 1;_x000D_
}_x000D_
.imgB1 {_x000D_
  z-index: 3;_x000D_
}

<img class="imgA1" src="https://placehold.it/200/333333">_x000D_
<img class="imgB1" src="https://placehold.it/100">

Source

This happened to me because I had a ddd() or dd();die; in my routes/web.php file I forgot about.

Provide the source image (img) size as the first rectangle:

ctx.drawImage(img, 0, 0, img.width,    img.height,     // source rectangle
                   0, 0, canvas.width, canvas.height); // destination rectangle

The second rectangle will be the destination size (what source rectangle will be scaled to).

Update 2016/6: For aspect ratio and positioning (ala CSS' "cover" method), check out:
Simulation background-size: cover in canvas

I just had to use @EnableAutoConfiguration to address it, however this error had no functional impact.

When making something like this the best solution is an recursive directive. However, when you make such an directive you find out that AngularJS gets into an endless loop.

The solution for this is to let the directive remove the element during the compile event, and manually compile and add them in the link events.

I found out about this in this thread, and abstracted this functionality into a service.

module.factory('RecursionHelper', ['$compile', function($compile){
    return {
        /**
         * Manually compiles the element, fixing the recursion loop.
         * @param element
         * @param [link] A post-link function, or an object with function(s) registered via pre and post properties.
         * @returns An object containing the linking functions.
         */
        compile: function(element, link){
            // Normalize the link parameter
            if(angular.isFunction(link)){
                link = { post: link };
            }

            // Break the recursion loop by removing the contents
            var contents = element.contents().remove();
            var compiledContents;
            return {
                pre: (link && link.pre) ? link.pre : null,
                /**
                 * Compiles and re-adds the contents
                 */
                post: function(scope, element){
                    // Compile the contents
                    if(!compiledContents){
                        compiledContents = $compile(contents);
                    }
                    // Re-add the compiled contents to the element
                    compiledContents(scope, function(clone){
                        element.append(clone);
                    });

                    // Call the post-linking function, if any
                    if(link && link.post){
                        link.post.apply(null, arguments);
                    }
                }
            };
        }
    };
}]);

With this service you can easily make a tree directive (or other recursive directives). Here is an example of an tree directive:

module.directive("tree", function(RecursionHelper) {
    return {
        restrict: "E",
        scope: {family: '='},
        template: 
            '<p>{{ family.name }}</p>'+
            '<ul>' + 
                '<li ng-repeat="child in family.children">' + 
                    '<tree family="child"></tree>' +
                '</li>' +
            '</ul>',
        compile: function(element) {
            return RecursionHelper.compile(element);
        }
    };
});

See this Plunker for a demo. I like this solution best because:

1. You don't need an special directive which makes your html less clean.
2. The recursion logic is abstracted away into the RecursionHelper service, so you keep your directives clean.

Update: Added support for a custom linking functions.

SELECT * FROM user_cons_columns WHERE table_name = 'table_name';

Approach 1 - flexbox

It works great for both known and unknown height elements. Make sure to set the outer div to height: 100%; and reset the default margin on body. See the browser support tables.

jsFiddle

html, body {_x000D_
  height: 100%;_x000D_
  margin: 0;_x000D_
}_x000D_
.wrapper {_x000D_
  height: 100%;_x000D_
  display: flex;_x000D_
  flex-direction: column;_x000D_
}_x000D_
.header, .footer {_x000D_
  background: silver;_x000D_
}_x000D_
.content {_x000D_
  flex: 1;_x000D_
  overflow: auto;_x000D_
  background: pink;_x000D_
}

<div class="wrapper">_x000D_
  <div class="header">Header</div>_x000D_
  <div class="content">_x000D_
    <div style="height:1000px;">Content</div>_x000D_
  </div>_x000D_
  <div class="footer">Footer</div>_x000D_
</div>

Approach 2 - CSS table

For both known and unknown height elements. It also works in legacy browsers including IE8.

jsFiddle

html, body {_x000D_
  height: 100%;_x000D_
  margin: 0;_x000D_
}_x000D_
.wrapper {_x000D_
  height: 100%;_x000D_
  width: 100%;_x000D_
  display: table;_x000D_
}_x000D_
.header, .content, .footer {_x000D_
  display: table-row;_x000D_
}_x000D_
.header, .footer {_x000D_
  background: silver;_x000D_
}_x000D_
.inner {_x000D_
  display: table-cell;_x000D_
}_x000D_
.content .inner {_x000D_
  height: 100%;_x000D_
  position: relative;_x000D_
  background: pink;_x000D_
}_x000D_
.scrollable {_x000D_
  position: absolute;_x000D_
  left: 0; right: 0;_x000D_
  top: 0; bottom: 0;_x000D_
  overflow: auto;_x000D_
}

<div class="wrapper">_x000D_
  <div class="header">_x000D_
    <div class="inner">Header</div>_x000D_
  </div>_x000D_
  <div class="content">_x000D_
    <div class="inner">_x000D_
      <div class="scrollable">_x000D_
        <div style="height:1000px;">Content</div>_x000D_
      </div>_x000D_
    </div>_x000D_
  </div>_x000D_
  <div class="footer">_x000D_
    <div class="inner">Footer</div>_x000D_
  </div>_x000D_
</div>

Approach 3 - calc()

If header and footer are fixed height, you can use CSS calc().

jsFiddle

html, body {_x000D_
  height: 100%;_x000D_
  margin: 0;_x000D_
}_x000D_
.wrapper {_x000D_
  height: 100%;_x000D_
}_x000D_
.header, .footer {_x000D_
  height: 50px;_x000D_
  background: silver;_x000D_
}_x000D_
.content {_x000D_
  height: calc(100% - 100px);_x000D_
  overflow: auto;_x000D_
  background: pink;_x000D_
}

<div class="wrapper">_x000D_
  <div class="header">Header</div>_x000D_
  <div class="content">_x000D_
    <div style="height:1000px;">Content</div>_x000D_
  </div>_x000D_
  <div class="footer">Footer</div>_x000D_
</div>

Approach 4 - % for all

If the header and footer are known height, and they are also percentage you can just do the simple math making them together of 100% height.

html, body {_x000D_
  height: 100%;_x000D_
  margin: 0;_x000D_
}_x000D_
.wrapper {_x000D_
  height: 100%;_x000D_
}_x000D_
.header, .footer {_x000D_
  height: 10%;_x000D_
  background: silver;_x000D_
}_x000D_
.content {_x000D_
  height: 80%;_x000D_
  overflow: auto;_x000D_
  background: pink;_x000D_
}

<div class="wrapper">_x000D_
  <div class="header">Header</div>_x000D_
  <div class="content">_x000D_
    <div style="height:1000px;">Content</div>_x000D_
  </div>_x000D_
  <div class="footer">Footer</div>_x000D_
</div>

First of all, a caveat. Why do you want to use telnet? telnet is an old protocol, unsafe and impractical for remote access. It's been (almost)totally replaced by ssh.

To answer your questions, it depends. It depends on the telnet client you use. If you use microsoft telnet, you can't. Microsoft telnet does not have any mean to send commands from a batch file or a command line.

I like Daniel Cerecedo's answer using toJSON() and regex. An even simpler form would be:

var now = new Date();
var regex = /^(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):(\d{2}).*$/;
var token_array = regex.exec(now.toJSON());
// [ "2017-10-31T02:24:45.868Z", "2017", "10", "31", "02", "24", "45" ]
var myFormat = token_array.slice(1).join('');
// "20171031022445"

I installed 32 bits ADT and It works fine without changing my configuration (Windows 7 64 bits, Java 6 32 bits).

I was finally able to get this to work for my needs.

The old voted up code does not run on windows 10 system (at least not mine). The referenced MS library link below provides current examples on how to make this work. My example uses them with late bindings.

https://docs.microsoft.com/en-us/windows/win32/shell/folder-getdetailsof.

The attribute codes were different on my computer and like someone mentioned above most return blank values even if they are not. I used a for loop to cycle through all of them and found out that Title and Subject can still be accessed which is more then enough for my purposes.

Private Sub MySubNamek()
Dim objShell  As Object 'Shell
Dim objFolder As Object 'Folder

Set objShell = CreateObject("Shell.Application")
Set objFolder = objShell.NameSpace("E:\MyFolder")

If (Not objFolder Is Nothing) Then
Dim objFolderItem As Object 'FolderItem
Set objFolderItem = objFolder.ParseName("Myfilename.txt")
        For i = 0 To 288
           szItem = objFolder.GetDetailsOf(objFolderItem, i)
           Debug.Print i & " - " & szItem
       Next
Set objFolderItem = Nothing
End If

Set objFolder = Nothing
Set objShell = Nothing
End Sub

You can specify a DOM attribute that can be used to allow the directive to define a function on the parent scope. The parent scope can then call this method like any other. Here's a plunker. And below is the relevant code.

clearfn is an attribute on the directive element into which the parent scope can pass a scope property which the directive can then set to a function that accomplish's the desired behavior.

            element.html('Hello World!');
            scope.clearFn = function(){
              element.html('');
            };

Public Sub SelectFirstBlankCell()
    Dim sourceCol As Integer, rowCount As Integer, currentRow As Integer
    Dim currentRowValue As String

    sourceCol = 6   'column F has a value of 6
    rowCount = Cells(Rows.Count, sourceCol).End(xlUp).Row

    'for every row, find the first blank cell and select it
    For currentRow = 1 To rowCount
        currentRowValue = Cells(currentRow, sourceCol).Value
        If IsEmpty(currentRowValue) Or currentRowValue = "" Then
            Cells(currentRow, sourceCol).Select
        End If
    Next
End Sub

If any column contains more than one empty cell continuously then this code will not work properly

JConsole is an easy way to monitor a running Java application or you can use a Profiler to get more detailed information on your application. I like using the NetBeans Profiler for this.

You should to choose Using Android Studio

Example Gradle file:

Note: Open the build.gradle file inside your application module directory.

apply plugin: 'com.android.application'

android {
    compileSdkVersion 20
    buildToolsVersion "20.0.0"

    defaultConfig {
        applicationId "{applicationId}"
        minSdkVersion 14
        targetSdkVersion 20
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            runProguard false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:20.+'
    compile 'com.google.android.gms:play-services:6.1.+'

Just set the display:none on the elements that you want to hide:

<table>
<tr><th>Test Table</th><tr>
<tr style="display:none"><td>1. 123456789</td><tr>
<tr><td>2. 123456789</td><tr>
<tr><td>3. 123456789</td><tr>
</table>

Look at PrinterSettings.InstalledPrinters

For your purposes, if all the items are stored as str and you just use sorted as you are using and then check for the first element and replace it with '0'

>>> l1 = ['88','NaN','67','89','81']
>>> n = sorted(l1,reverse=True)
['NaN', '89', '88', '81', '67']
>>> import math
>>> if math.isnan(float(n[0])):
...     n[0] = '0'
... 
>>> n
['0', '89', '88', '81', '67']

condition1 = False
condition2 = False
val = -1
#here is the function getstuff is not defined, i hope you define it before
#calling it into while loop code

while condition1 and condition2 is False and val == -1:
#as you can see above , we can write that in a simplified syntax.
    val,something1,something2 = getstuff()

    if something1 == 10:
        condition1 = True

    elif something2 == 20:
# here you don't have to use "if" over and over, if have to then write "elif" instead    
    condition2 = True
# ihope it can be helpfull

I've been willing to use something like this in a sheet where all lines are identical and usually refer to other cells in the same line - but as the formulas get complex, the references to other columns get hard to read. I tried the trick given in other answers, with for example column A named as "Sales" I can refers to it as INDEX(Sales;row()) but I found it a bit too long for my tastes.

However, in this particular case, I found that using Sales alone works just as well - Excel (2010 here) just gets the corresponding row automatically.

It appears to work with other ranges too; for example let's say I have values in A2:A11 which I name Sales, I can just use =Sales*0.21 in B2:11 and it will use the same row value, giving out ten different results.

I also found a nice trick on this page: named ranges can also be relative. Going back to your original question, if your value "Age" is in column A and assuming you're using that value in formulas in the same line, you can define Age as being $A2 instead of $A$2, so that when used in B5 or C5 for example, it will actually refer to $A5. (The Name Manager always show the reference relative to the cell currently selected)

1) you are calling it wrong way try:

$(input[name="searchBar"]).val('hi')

2) if it doesn't work call your .js file at the end of the page or trigger your function on document.ready event

$(document).ready(function() {
  $(input[name="searchBar"]).val('hi');
});

I built an extension called Checkpoints, an alternative to Local History. Checkpoints has support for viewing history for all files (that has checkpoints) in the tree view, not just the currently active file. There are some other minor differences aswell, but overall they are pretty similar.

Ok, Denizens. So I have accepted the command line length limits as gospel for quite some time. So, what to do with one's assumptions? Naturally- check them.

I have a Fedora 22 machine at my disposal (meaning: Linux with bash4). I have created a directory with 500,000 inodes (files) in it each of 18 characters long. The command line length is 9,500,000 characters. Created thus:

seq 1 500000 | while read digit; do
    touch $(printf "abigfilename%06d\n" $digit);
done

And we note:

$ getconf ARG_MAX
2097152

Note however I can do this:

$ echo * > /dev/null

But this fails:

$ /bin/echo * > /dev/null
bash: /bin/echo: Argument list too long

I can run a for loop:

$ for f in *; do :; done

which is another shell builtin.

Careful reading of the documentation for ARG_MAX states, Maximum length of argument to the exec functions. This means: Without calling exec, there is no ARG_MAX limitation. So it would explain why shell builtins are not restricted by ARG_MAX.

And indeed, I can ls my directory if my argument list is 109948 files long, or about 2,089,000 characters (give or take). Once I add one more 18-character filename file, though, then I get an Argument list too long error. So ARG_MAX is working as advertised: the exec is failing with more than ARG_MAX characters on the argument list- including, it should be noted, the environment data.

Other than that your variable declarations have syntax errors, this works exactly how you expected it to. All you have to do is cast a and b to Double and pass the values to pow. Then, if you're working with 2 Ints and you want an Int back on the other side of the operation, just cast back to Int.

import Darwin 

let a: Int = 3
let b: Int = 3

let x: Int = Int(pow(Double(a),Double(b)))

Better way is to skip the Entity Framework entirely for this operation and rely on SqlBulkCopy class. Other operations can continue using EF as before.

That increases the maintenance cost of the solution, but anyway helps reduce time required to insert large collections of objects into the database by one to two orders of magnitude compared to using EF.

Here is an article that compares SqlBulkCopy class with EF for objects with parent-child relationship (also describes changes in design required to implement bulk insert): How to Bulk Insert Complex Objects into SQL Server Database

You can use cvResize. Or better use c++ interface (eg cv::Mat instead of IplImage and cv::imread instead of cvLoadImage) and then use cv::resize which handles memory allocation and deallocation itself.

In a class that extends a javax.swing.JFrame use method setIconImage.

this.setIconImage(new ImageIcon(getClass().getResource("/resource/icon.png")).getImage());

The reason people often suggest writing

VAR=value
export VAR

instead of the shorter

export VAR=value

is that the longer form works in more different shells than the short form. If you know you're dealing with bash, either works fine, of course.

The text uses combining characters, also known as combining marks. See section 2.11 of Combining Characters in the Unicode Standard (PDF).

In Unicode, character rendering does not use a simple character cell model where each glyph fits into a box with given height. Combining marks may be rendered above, below, or inside a base character

So you can easily construct a character sequence, consisting of a base character and “combining above” marks, of any length, to reach any desired visual height, assuming that the rendering software conforms to the Unicode rendering model. Such a sequence has no meaning of course, and even a monkey could produce it (e.g., given a keyboard with suitable driver).

And you can mix “combining above” and “combining below” marks.

The sample text in the question starts with:

• LATIN CAPITAL LETTER H - H
• COMBINING LATIN SMALL LETTER T - ͭ
• COMBINING GREEK KORONIS - ̓
• COMBINING COMMA ABOVE - ̓
• COMBINING DOT ABOVE - ̇

Call dict with no parameters

new_dict = dict()

or simply write

new_dict = {}

This error occurs when you have configured your application with IIS, and IIS goes to SQL Server and tries to login with credentials that do not have proper permissions. This error can also occur when replication or mirroring is set up. I will be going over a solution that works always and is very simple. Go to SQL Server >> Security >> Logins and right click on NT AUTHORITY\NETWORK SERVICE and select Properties

In newly opened screen of Login Properties, go to the “User Mapping” tab. Then, on the “User Mapping” tab, select the desired database – especially the database for which this error message is displayed. On the lower screen, check the role db_owner. Click OK.

For linux users, and to sum up and add to what others have said here, you should know the following:

1. Global variables are not evil. $CLASSPATH is specifically what Java uses to look through multiple directories to find all the different classes it needs for your script (unless you explicitly tell it otherwise with the -cp override).

2. The colon (":") character separates the different directories. There is only one $CLASSPATH and it has all the directories in it. So, when you run "export CLASSPATH=...." you want to include the current value "$CLASSPATH" in order to append to it. For example:

   export CLASSPATH=.
   export CLASSPATH=$CLASSPATH:/usr/share/java/mysql-connector-java-5.1.12.jar
   

   In the first line above, you start CLASSPATH out with just a simple 'dot' which is the path to your current working directory. With that, whenever you run java it will look in the current working directory (the one you're in) for classes. In the second line above, $CLASSPATH grabs the value that you previously entered (.) and appends the path to a mysql dirver. Now, java will look for the driver AND for your classes.

3. echo $CLASSPATH
   

   is super handy, and what it returns should read like a colon-separated list of all the directories you want java looking in for what it needs to run your script.

4. Tomcat does not use CLASSPATH. Read what to do about that here: https://tomcat.apache.org/tomcat-8.0-doc/class-loader-howto.html

No CURSOR, WHILE loop, or User-Defined Function needed.

Just need to be creative with FOR XML and PATH.

[Note: This solution only works on SQL 2005 and later. Original question didn't specify the version in use.]

In my case just changing the permissions of anaconda folder worked:

sudo chmod -R u=rwx,g=rx,o=rx /path/to/anaconda   

If you are redirecting with PHP, then you would simply use the sleep() command to sleep for however many seconds before redirecting.

But, I think what you are referring to is the meta refresh tag:

okay, thx a lot now i use sth like this:

public static String[] removeElements(String[] input, String deleteMe) {
    if (input != null) {
        List<String> list = new ArrayList<String>(Arrays.asList(input));
        for (int i = 0; i < list.size(); i++) {
            if (list.get(i).equals(deleteMe)) {
                list.remove(i);
            }
        }
        return list.toArray(new String[0]);
    } else {
        return new String[0];
    }
}

I just came across this: Eclipse Colour Themes

Install the plugin and choose from a selection of pre-defined themes, or write your own. Just what I needed!

Keep the viewport untouched: <meta name="viewport" content="width=device-width, initial-scale=1.0">

Assuming you would like to achieve the effect of a continuous black bar to the right side: #menubar shouldn't exceed 100%, adjust the border radius such that the right side is squared and adjust the padding so that it extends a little more to the right. Modify the following to your #menubar:

border-radius: 30px 0px 0px 30px;
width: 100%; /*setting to 100% would leave a little space to the right */
padding: 0px 0px 0px 10px; /*fills the little gap*/

Adjusting the padding to 10px of course leaves the left menu to the edge of the bar, you can put the remaining 40px to each of the li, 20px on each side left and right:

.menuitem {
display: block;
padding: 0px 20px;
}

When you resize the browser smaller, you would find still the white background: place your background texture instead from your div to body. Or alternatively, adjust the navigation menu width from 100% to lower value using media queries. There are a lot of adjustments to be made to your code to create a proper layout, I'm not sure what you intend to do but the above code will somehow fix your overflowing bar.

Place the link location in the action="" of a wrapping form tag.

Your first link would be:

<form action="1.html">
    <input type="submit" class="button_active" value="1">
</form>

I was having this issue with a linked server in SSMS while trying to create a stored procedure.

On the linked server, I changed the server option "Enable Promotion on Distributed Transaction" to False.

For myself, I would assume unsigned int is platform specific. Integer could be 8 bits, 16 bits, 32 bits or even 64 bits.

DWORD in the other hand, specifies its own size, which is Double Word. Word are 16 bits so DWORD will be known as 32 bit across all platform

filter_input(INPUT_POST, 'var_name') instead of $_POST['var_name']
filter_input_array(INPUT_POST) instead of $_POST

Already there are lots of answers to your question, You can do it like this also. You can give your table an alias name and use that in the select query like this:

SELECT a.id, b.id, name, section
FROM tbl_names as a 
LEFT JOIN tbl_section as b ON a.id = b.id;
