Similarly if you want link through s3Client you can use below.

System.out.println("filelink: " + s3Client.getUrl("your_bucket_name", "your_file_key"));

In the context of AngularJS, the $ prefix is used only for identifiers in the framework's code. Users of the framework are instructed not to use it in their own identifiers:

Angular Namespaces $ and $$

To prevent accidental name collisions with your code, Angular prefixes names of public objects with $ and names of private objects with $$. Please do not use the $ or $$ prefix in your code.

Windows Services do not have UIs. You can redirect the output from a console app to your service with the code shown in this question.

A simple searchable goto for the use of commenting out code blocks when debugging.

GOTO=false
if ${GOTO}; then
    echo "GOTO failed"
    ...
fi # End of GOTO
echo "GOTO done"

Result is-> GOTO done

The declare array doesn't work for Korn shell. Use the below example for the Korn shell:

promote_sla_chk_lst="cdi xlob"

set -A promote_arry $promote_sla_chk_lst

for i in ${promote_arry[*]};
    do
            echo $i
    done

DELETE FROM on_search WHERE search_date < NOW() - INTERVAL N DAY

Heres an easy way to do find the keys of a given value:

    clients = {
      "yellow"=>{"client_id"=>"2178"}, 
      "orange"=>{"client_id"=>"2180"}, 
      "red"=>{"client_id"=>"2179"}, 
      "blue"=>{"client_id"=>"2181"}
    }

    p clients.rassoc("client_id"=>"2180")

...and to find the value of a given key:

    p clients.assoc("orange") 

it will give you the key-value pair.

First add an Enrty and Category class:

public class Entry {     public string Id { get; set; }     public string Title { get; set; }     public string Updated { get; set; }     public string Summary { get; set; }     public string GPoint { get; set; }     public string GElev { get; set; }     public List<string> Categories { get; set; } }  public class Category {     public string Label { get; set; }     public string Term { get; set; } } 

Then use LINQ to XML

XDocument xDoc = XDocument.Load("path");          List<Entry> entries = (from x in xDoc.Descendants("entry")             select new Entry()             {                 Id = (string) x.Element("id"),                 Title = (string)x.Element("title"),                 Updated = (string)x.Element("updated"),                 Summary = (string)x.Element("summary"),                 GPoint = (string)x.Element("georss:point"),                 GElev = (string)x.Element("georss:elev"),                 Categories = (from c in x.Elements("category")                                   select new Category                                   {                                       Label = (string)c.Attribute("label"),                                       Term = (string)c.Attribute("term")                                   }).ToList();             }).ToList(); 

In response to jt. You are correct, the HTML with just the password is susceptible to the Man in the middle attack. However, you can seed it with a GUID from the server ...

$.post(
  'includes/login.php', 
  { user: username, pass: $.md5(password + GUID) },
   onLogin, 
  'json' );

This would defeat the Man-In-The middle ... in that the server would generate a new GUID for each attempt.

in order to know the phone resolution simply create a image with label mdpi, hdpi, xhdpi and xxhdpi. put these images in respective folder like mdpi, hdpi, xhdpi and xxhdpi. create a image view in layout and load this image. the phone will load the respective image from a specific folder. by this you will get the phone resolution or *dpi it is using.

To understand, let's consider below code snippet:

struct Foo{};
struct Bar{};

int main(int argc, char** argv)
{
    Foo* f = new Foo;

    Bar* b1 = f;                              // (1)
    Bar* b2 = static_cast<Bar*>(f);           // (2)
    Bar* b3 = dynamic_cast<Bar*>(f);          // (3)
    Bar* b4 = reinterpret_cast<Bar*>(f);      // (4)
    Bar* b5 = const_cast<Bar*>(f);            // (5)

    return 0;
}

Only line (4) compiles without error. Only reinterpret_cast can be used to convert a pointer to an object to a pointer to an any unrelated object type.

One this to be noted is: The dynamic_cast would fail at run-time, however on most compilers it will also fail to compile because there are no virtual functions in the struct of the pointer being casted, meaning dynamic_cast will work with only polymorphic class pointers.

When to use C++ cast:

• Use static_cast as the equivalent of a C-style cast that does value conversion, or when we need to explicitly up-cast a pointer from a class to its superclass.
• Use const_cast to remove the const qualifier.
• Use reinterpret_cast to do unsafe conversions of pointer types to and from integer and other pointer types. Use this only if we know what we are doing and we understand the aliasing issues.

You could use the ready to use Url Rewrite Filter with a rule like this one:

<rule>
  <from>^/Check_License/Dir_My_App/Dir_ABC/My_Obj_([0-9]+)$</from>
  <to>/Check_License?Contact_Id=My_Obj_$1</to>
</rule>

I have recently tried the following approach which seems to work fine, although I am not 100% sure if there might be any side effects:

'use strict';

import * as models from "../../models";

module.exports = {

  up: function (queryInterface, Sequelize) {

    return queryInterface.createTable(models.Role.tableName, models.Role.attributes)
    .then(() => queryInterface.createTable(models.Team.tableName, models.Team.attributes))
    .then(() => queryInterface.createTable(models.User.tableName, models.User.attributes))

  },

  down: function (queryInterface, Sequelize) {
    ...
  }

};

When running the migration above using sequelize db:migrate, my console says:

Starting 'db:migrate'...
Finished 'db:migrate' after 91 ms
== 20160113121833-create-tables: migrating =======
== 20160113121833-create-tables: migrated (0.518s)

All the tables are there, everything (at least seems to) work as expected. Even all the associations are there if they are defined correctly.

I ran into the same problem. My fix was changing <parameter value="v12.0" /> to <parameter value="mssqllocaldb" /> into the "app.config" file.

Or you could use dsquery and dsget:

dsquery user domainroot -name <userName> | dsget user -memberof

To retrieve group memberships something like this:

Tue 09/10/2013 13:17:41.65
C:\
>dsquery user domainroot -name jqpublic | dsget user -memberof
"CN=Technical Support Staff,OU=Acme,OU=Applications,DC=YourCompany,DC=com"
"CN=Technical Support Staff,OU=Contosa,OU=Applications,DC=YourCompany,DC=com"
"CN=Regional Administrators,OU=Workstation,DC=YourCompany,DC=com"

Although I can't find any evidence that I ever installed this package on my computer, you might need to install the Remote Server Administration Tools for Windows 7.

The C# language doesn't have a power operator. However, the .NET Framework offers the Math.Pow method:

Returns a specified number raised to the specified power.

So your example would look like this:

float Result, Number1, Number2;

Number1 = 2;
Number2 = 2;

Result = Math.Pow(Number1, Number2);

Warning: if you need update Node from an old version (in my case v4.6.0) it is better to re-install nodejs from scratch (download link: https://nodejs.org) otherwise npm will also update itself to a version that's not compatible with the new Node (see this discussion).

This is the error message that I got after updating Node (on Windows) with npm

Instead of taking the HttpServletRequest object in every method, keep in controllers' context by auto-wiring via the constructor. Then you can access from all methods of the controller.

public class OAuth2ClientController {
    @Autowired
    private OAuth2ClientService oAuth2ClientService;

    private HttpServletRequest request;

    @Autowired
    public OAuth2ClientController(HttpServletRequest request) {
        this.request = request;
    }

    @RequestMapping(method = RequestMethod.POST)
    public ResponseEntity<String> createClient(@RequestBody OAuth2Client client) {
        System.out.println(request.getRequestURI());
        System.out.println(request.getHeader("Content-Type"));

        return ResponseEntity.ok();
    }

I noticed one error in Dave Ward's answer (perhaps a recent change?): The query string paramaters are in request.query, not request.params. (See https://stackoverflow.com/a/6913287/166530 )

request.params by default is filled with the value of any "component matches" in routes, i.e.

app.get('/user/:id', function(request, response){
  response.send('user ' + request.params.id);
});

and, if you have configured express to use its bodyparser (app.use(express.bodyParser());) also with POST'ed formdata. (See How to retrieve POST query parameters? )

THE CORRECT WAY ************************ THE CORRECT WAY

while($rows[] = mysqli_fetch_assoc($result));
array_pop($rows);  // pop the last row off, which is an empty row

You can select the form like this:

$("#submit").click(function(){
    var form = $(this).parents('form:first');
    ...
});

However, it is generally better to attach the event to the submit event of the form itself, as it will trigger even when submitting by pressing the enter key from one of the fields:

$('form#myform1').submit(function(e){
     e.preventDefault(); //Prevent the normal submission action
     var form = this;
     // ... Handle form submission
});

To select fields inside the form, use the form context. For example:

$("input[name='somename']",form).val();

try to put the path in the system variables instead of putting in user variables in environment variables.

Here is the simplest solution

select m_id,v_id,max(timestamp) from table group by m_id;

Group by m_id but get max of timestamp for each m_id.

This would be better approach as I have implemented :)

@model ObjectUser
@using System.Web.Script.Serialization
@{ 
    var javaScriptSearilizer = new JavaScriptSerializer();
    var searializedObject = javaScriptSearilizer.Serialize(Model);
 }

<script>
    var searializedObject = @Html.Raw(searializedObject )
    console.log(searializedObject);
    alert(searializedObject);
</script>

Hope this will help you to prevent you from iterating model ( happy coding )

I suggest an addition to the behavior provided by Steve Greatrex. His behavior doesn't reflects changes from the source because it may not be a collection of TreeViewItems. So it is a matter of finding the TreeViewItem in the tree which datacontext is the selectedValue from the source. The TreeView has a protected property called "ItemsHost", which holds the TreeViewItem collection. We can get it through reflection and walk the tree searching for the selected item.

private static void OnSelectedItemChanged(DependencyObject sender, DependencyPropertyChangedEventArgs e)
    {
        var behavior = sender as BindableSelectedItemBehaviour;

        if (behavior == null) return;

        var tree = behavior.AssociatedObject;

        if (tree == null) return;

        if (e.NewValue == null) 
            foreach (var item in tree.Items.OfType<TreeViewItem>())
                item.SetValue(TreeViewItem.IsSelectedProperty, false);

        var treeViewItem = e.NewValue as TreeViewItem; 
        if (treeViewItem != null)
        {
            treeViewItem.SetValue(TreeViewItem.IsSelectedProperty, true);
        }
        else
        {
            var itemsHostProperty = tree.GetType().GetProperty("ItemsHost", System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Instance);

            if (itemsHostProperty == null) return;

            var itemsHost = itemsHostProperty.GetValue(tree, null) as Panel;

            if (itemsHost == null) return;

            foreach (var item in itemsHost.Children.OfType<TreeViewItem>())
                if (WalkTreeViewItem(item, e.NewValue)) break;
        }
    }

    public static bool WalkTreeViewItem(TreeViewItem treeViewItem, object selectedValue) {
        if (treeViewItem.DataContext == selectedValue)
        {
            treeViewItem.SetValue(TreeViewItem.IsSelectedProperty, true);
            treeViewItem.Focus();
            return true;
        }

        foreach (var item in treeViewItem.Items.OfType<TreeViewItem>())
            if (WalkTreeViewItem(item, selectedValue)) return true;

        return false;
    }

This way the behavior works for two-way bindings. Alternatively, it is possible to move the ItemsHost acquisition to the Behavior's OnAttached method, saving the overhead of using reflection every time the binding updates.

Just set targetSdkVersion to 19. The notification icon will be colored. Then wait for Firebase to fix this issue.

[ ] - this is used whenever we are declaring an empty array,

{ } - this is used whenever we declare an empty object

typeof([ ]) //object

typeof({ }) //object

but if your run

[ ].constructor.name  //Array

so from this, you will understand it is an array here Array is the name of the base class. The JavaScript Array class is a global object that is used in the construction of arrays which are high-level, list-like objects.

If you want to replace lot of values in single go, you can use 'library(car)'.

Example

library(car)

x <- rep(1:5,3)

xr <- recode(x, '3=1; 4=2')

x
## [1] 1 2 3 4 5 1 2 3 4 5 1 2 3 4 5
xr
## [1] 1 2 1 2 5 1 2 1 2 5 1 2 1 2 5

You are getting this error because the value cannot be found in the range. String or integer doesn't matter. Best thing to do in my experience is to do a check first to see if the value exists.

I used CountIf below, but there is lots of different ways to check existence of a value in a range.

Public Sub test()

Dim rng As Range
Dim aNumber As Long

aNumber = 666

Set rng = Sheet5.Range("B16:B615")

    If Application.WorksheetFunction.CountIf(rng, aNumber) > 0 Then

        rowNum = Application.WorksheetFunction.Match(aNumber, rng, 0)

    Else
        MsgBox aNumber & " does not exist in range " & rng.Address
    End If

End Sub

ALTERNATIVE WAY

Public Sub test()
    Dim rng As Range
    Dim aNumber As Variant
    Dim rowNum As Long

    aNumber = "2gg"

    Set rng = Sheet5.Range("B1:B20")

    If Not IsError(Application.Match(aNumber, rng, 0)) Then
        rowNum = Application.Match(aNumber, rng, 0)
        MsgBox rowNum
    Else
        MsgBox "error"
    End If
End Sub

OR

Public Sub test()
    Dim rng As Range
    Dim aNumber As Variant
    Dim rowNum As Variant

    aNumber = "2gg"

    Set rng = Sheet5.Range("B1:B20")

    rowNum = Application.Match(aNumber, rng, 0)

    If Not IsError(rowNum) Then
        MsgBox rowNum
    Else
        MsgBox "error"
    End If
End Sub

For me works fine:

@RequestMapping (value = "/{id}", method = RequestMethod.GET)
public ResponseEntity<Object> redirectToExternalUrl() throws URISyntaxException {
    URI uri = new URI("http://www.google.com");
    HttpHeaders httpHeaders = new HttpHeaders();
    httpHeaders.setLocation(uri);
    return new ResponseEntity<>(httpHeaders, HttpStatus.SEE_OTHER);
}

You can use the workbook.get_worksheet_by_name() feature: https://xlsxwriter.readthedocs.io/workbook.html#get_worksheet_by_name

According to https://xlsxwriter.readthedocs.io/changes.html the feature has been added on May 13, 2016.

"Release 0.8.7 - May 13 2016

-Fix for issue when inserting read-only images on Windows. Issue #352.

-Added get_worksheet_by_name() method to allow the retrieval of a worksheet from a workbook via its name.

-Fixed issue where internal file creation and modification dates were in the local timezone instead of UTC."

map.keySet()

will return you all the keys. If you want the keys to be sorted, you might consider a TreeMap

Just another viewpoint. Performing an "or" in Prolog can also be done with the "disjunct" operator or semi-colon:

I tried all of above. What helps me:

1. Download the mingw-get.
2. Setup it.
3. Add something like this C:\MinGW\bin to environment variables.
4. Launch (!important) git bash. Power shell, developer vs cmd, system cmd etc did'nt help.
5. Type mingw-get into command line.
6. After type mingw-get install mingw32-make.
7. Copy and paste all files from C:\MinGW\bin to folder where your Makefile is. Done! Now You might be able to use make-commands in this folder.

You can't, not if you are talking about applications built with the official SDK and deploying straight from xcode.

Let me answer your 3rd question first:

If you want to run a self-compiled version within a conda-env, you can. These are the general instructions I run to get tensorflow to install on my system with additional instructions. Note: This build was for an AMD A10-7850 build (check your CPU for what instructions are supported...it may differ) running Ubuntu 16.04 LTS. I use Python 3.5 within my conda-env. Credit goes to the tensorflow source install page and the answers provided above.

git clone https://github.com/tensorflow/tensorflow 
# Install Bazel
# https://bazel.build/versions/master/docs/install.html
sudo apt-get install python3-numpy python3-dev python3-pip python3-wheel
# Create your virtual env with conda.
source activate YOUR_ENV
pip install six numpy wheel, packaging, appdir
# Follow the configure instructions at:
# https://www.tensorflow.org/install/install_sources
# Build your build like below. Note: Check what instructions your CPU 
# support. Also. If resources are limited consider adding the following 
# tag --local_resources 2048,.5,1.0 . This will limit how much ram many
# local resources are used but will increase time to compile.
bazel build -c opt --copt=-mavx --copt=-msse4.1 --copt=-msse4.2  -k //tensorflow/tools/pip_package:build_pip_package
# Create the wheel like so:
bazel-bin/tensorflow/tools/pip_package/build_pip_package /tmp/tensorflow_pkg
# Inside your conda env:
pip install /tmp/tensorflow_pkg/NAME_OF_WHEEL.whl
# Then install the rest of your stack
pip install keras jupyter etc. etc.

As to your 2nd question:

A self-compiled version with optimizations are well worth the effort in my opinion. On my particular setup, calculations that used to take 560-600 seconds now only take about 300 seconds! Although the exact numbers will vary, I think you can expect about a 35-50% speed increase in general on your particular setup.

Lastly your 1st question:

A lot of the answers have been provided above already. To summarize: AVX, SSE4.1, SSE4.2, MFA are different kinds of extended instruction sets on X86 CPUs. Many contain optimized instructions for processing matrix or vector operations.

I will highlight my own misconception to hopefully save you some time: It's not that SSE4.2 is a newer version of instructions superseding SSE4.1. SSE4 = SSE4.1 (a set of 47 instructions) + SSE4.2 (a set of 7 instructions).

In the context of tensorflow compilation, if you computer supports AVX2 and AVX, and SSE4.1 and SSE4.2, you should put those optimizing flags in for all. Don't do like I did and just go with SSE4.2 thinking that it's newer and should superseed SSE4.1. That's clearly WRONG! I had to recompile because of that which cost me a good 40 minutes.

In Eclipse, actions like importing Maven projects or invoking "Update Sources" runs in the same JVM in which Eclipse is running. If that JVM comes from JRE that isn’t part of JDK, there would be no Java compiler (the tools.jar).

So to launch Maven from within Eclipse, JRE used for launch also need to come from JDK. By default Eclipse registers JRE it is started in, but this can be configured on "Window / Preferences… / Java / Installed JREs" preference page as mentioned above by Parthasarathy

Alternatively you can specify compilerId in the pom.xml, so Maven won’t be looking for JDK when compiling Java code:

 <plugin>
  <artifactid>maven-compiler-plugin</artifactid>
  <configuration>
    <compilerid>eclipse</compilerid>
  </configuration>
  <dependencies>
    <dependency>
      <groupid>org.codehaus.plexus</groupid>
      <artifactid>plexus-compiler-eclipse</artifactid>
      <version>xxxx</version>
    </dependency>
  </dependencies>
</plugin>

Now, i'm being told that this will terminate the session (or is it all sessions?) in the 15th minute of use, regardless their activity.

This is wrong. It will just kill the session when the associated client (webbrowser) has not accessed the website for more than 15 minutes. The activity certainly counts, exactly as you initially expected, seeing your attempt to solve this.

The HttpSession#setMaxInactiveInterval() doesn't change much here by the way. It does exactly the same as <session-timeout> in web.xml, with the only difference that you can change/set it programmatically during runtime. The change by the way only affects the current session instance, not globally (else it would have been a static method).

To play around and experience this yourself, try to set <session-timeout> to 1 minute and create a HttpSessionListener like follows:

@WebListener
public class HttpSessionChecker implements HttpSessionListener {

    public void sessionCreated(HttpSessionEvent event) {
        System.out.printf("Session ID %s created at %s%n", event.getSession().getId(), new Date());
    }

    public void sessionDestroyed(HttpSessionEvent event) {
        System.out.printf("Session ID %s destroyed at %s%n", event.getSession().getId(), new Date());
    }

}

(if you're not on Servlet 3.0 yet and thus can't use @WebListener, then register in web.xml as follows):

<listener>
    <listener-class>com.example.HttpSessionChecker</listener-class>
</listener>

Note that the servletcontainer won't immediately destroy sessions after exactly the timeout value. It's a background job which runs at certain intervals (e.g. 5~15 minutes depending on load and the servletcontainer make/type). So don't be surprised when you don't see destroyed line in the console immediately after exactly one minute of inactivity. However, when you fire a HTTP request on a timed-out-but-not-destroyed-yet session, it will be destroyed immediately.

Have you looked at the samples provided with EPPlus?

This one shows you how to create a file http://epplus.codeplex.com/wikipage?title=ContentSheetExample

This one shows you how to use it to stream back a file http://epplus.codeplex.com/wikipage?title=WebapplicationExample

This is how we use the package to generate a file.

var newFile = new FileInfo(ExportFileName);
using (ExcelPackage xlPackage = new ExcelPackage(newFile))
{                       
    // do work here                            
    xlPackage.Save();
}

Actually, it's because CSS defines 100% relative to the entire width of the container, including its margins, borders, and padding; that means that the space avail. to its contents is some amount smaller than 100%, unless the container has no margins, borders, or padding.

This is counter-intuitive and widely regarded by many to be a mistake that we are now stuck with. It effectively means that % dimensions are no good for anything other than a top level container, and even then, only if it has no margins, borders or padding.

Note that the text field's margins, borders, and padding are included in the CSS size specified for it - it's the container's which throw things off.

I have tolerably worked around it by using 98%, but that is a less than perfect solution, since the input fields tend to fall further short as the container gets larger.

EDIT: I came across this similar question - I've never tried the answer given, and I don't know for sure if it applies to your problem, but it seems like it will.

The reason the functionality was removed from Django originally was that the header cannot ultimately be trusted. The reason is that it is easy to spoof. For example the recommended way to configure an nginx reverse proxy is to:

add_header X-Forwarded-For $proxy_add_x_forwarded_for;
add_header X-Real-Ip       $remote_addr;

When you do:

curl -H 'X-Forwarded-For: 8.8.8.8, 192.168.1.2' http://192.168.1.3/

Your nginx in myhost.com will send onwards:

X-Forwarded-For: 8.8.8.8, 192.168.1.2, 192.168.1.3

The X-Real-IP will be the IP of the first previous proxy if you follow the instructions blindly.

In case trusting who your users are is an issue, you could try something like django-xff: https://pypi.python.org/pypi/django-xff/

I have often had a similar problem; Python programs I write frequently need to have the ability to execute some primary functionality while simultaneously accepting user input from the command line (stdin). Simply putting the user input handling functionality in another thread doesn't solve the problem because readline() blocks and has no timeout. If the primary functionality is complete and there is no longer any need to wait for further user input I typically want my program to exit, but it can't because readline() is still blocking in the other thread waiting for a line. A solution I have found to this problem is to make stdin a non-blocking file using the fcntl module:

import fcntl
import os
import sys

# make stdin a non-blocking file
fd = sys.stdin.fileno()
fl = fcntl.fcntl(fd, fcntl.F_GETFL)
fcntl.fcntl(fd, fcntl.F_SETFL, fl | os.O_NONBLOCK)

# user input handling thread
while mainThreadIsRunning:
      try: input = sys.stdin.readline()
      except: continue
      handleInput(input)

In my opinion this is a bit cleaner than using the select or signal modules to solve this problem but then again it only works on UNIX...

Check if you are building for device instead of simulator. Go to Xcode menu 'Project' -> 'Set Active SDK' change from 'Device' to 'Simulator'

Under Xcode 4.1 Check your build settings for the project and your targets. For each check under 'Code Signing' check 'Code Signing Identity' and change over to 'Don't Code Sign'

Had this problem couldn't find the answer so i went looking on other threads, I found that i was making my app with 1.8 but for some reason my jre was out dated even though i remember updating it. I downloaded the lastes jre 8 and the jar file runs perfectly. Hope this helps.

My answer is similar to jh314's answer but I'll explain a little deeper.

What you should do in this case is:

int a = 1;
char b = (char)(a + '0');
System.out.println(b);

Here, we used '0' because chars are actually represented by ASCII values. '0' is a char and represented by the value of 48.

We typed (a + '0') and in order to add these up, Java converted '0' to its ASCII value which is 48 and a is 1 so the sum is 49. Then what we did is:

(char)(49)

We casted int to char. ASCII equivalent of 49 is '1'. You can convert any digit to char this way and is smarter and better way than using .toString() method and then subtracting the digit by .charAt() method.

sudo lsof -i:8080

By running the above command you can see what are all the jobs running.

kill -9 <PID Number>

Enter the PID (process identification number), so this will terminate/kill the instance.

TRY:

SELECT EXTRACT(YEAR FROM (STR_TO_DATE(subdateshow, '%d/%m/%Y')));

I'm not sure if I'm right, or I'm missing something, but as for now (2016-07-11, running Win7 Enterprise SP1) a LNK file adapts itself on moving or even changing the drive letter after it is run at a new place! I created a new shortcut on my USB drive and tried moving the shortcut and its target in a way that the relative position stayed unchanged, then I changed the drive letter. The shortcut worked in both cases and the target field was adapted after I double-clicked it.

It looks like Microsoft has addressed this issue in one of the past updates.

Please somebody confirm this.

If you return a serializable object, WebAPI will automatically send JSON or XML based on the Accept header that your client sends.

If you return a string, you'll get a string.

C# will allow you to have a string split over multiple lines, the term is called verbatim literal:

string myString = @"this is a
                    test
                   to see how long my string
                   can be



                    and it can be quite long";

If you are looking for the alternative to & _ from VB, use the + to join your lines.

You can use the following code to check if a textbox object is null/empty

'Checks if the box is null

If Me.TextBox & "" <> "" Then

        'Enter Code here...

End if

It seems like you can also use the patch command. Put the diff in the root of the repository and run patch from the command line.

patch -i yourcoworkers.diff

or

patch -p0 -i yourcoworkers.diff

You may need to remove the leading folder structure if they created the diff without using --no-prefix.

If so, then you can remove the parts of the folder that don't apply using:

patch -p1 -i yourcoworkers.diff

The -p(n) signifies how many parts of the folder structure to remove.

More information on creating and applying patches here.

You can also use

git apply yourcoworkers.diff --stat 

to see if the diff by default will apply any changes. It may say 0 files affected if the patch is not applied correctly (different folder structure).

The major difference is that:

• CSS resets aim to remove all built-in browser styling. Standard elements like H1-6, p, strong, em, et cetera end up looking exactly alike, having no decoration at all. You're then supposed to add all decoration yourself.

• Normalize CSS aims to make built-in browser styling consistent across browsers. Elements like H1-6 will appear bold, larger et cetera in a consistent way across browsers. You're then supposed to add only the difference in decoration your design needs.

If your design a) follows common conventions for typography et cetera, and b) Normalize.css works for your target audience, then using Normalize.CSS instead of a CSS reset will make your own CSS smaller and faster to write.

I check for both Wi-fi and Mobile internet as follows...

private boolean haveNetworkConnection() {
    boolean haveConnectedWifi = false;
    boolean haveConnectedMobile = false;

    ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfo[] netInfo = cm.getAllNetworkInfo();
    for (NetworkInfo ni : netInfo) {
        if (ni.getTypeName().equalsIgnoreCase("WIFI"))
            if (ni.isConnected())
                haveConnectedWifi = true;
        if (ni.getTypeName().equalsIgnoreCase("MOBILE"))
            if (ni.isConnected())
                haveConnectedMobile = true;
    }
    return haveConnectedWifi || haveConnectedMobile;
}

Obviously, It could easily be modified to check for individual specific connection types, e.g., if your app needs the potentially higher speeds of Wi-fi to work correctly etc.

If you ever get similar errors when using Windows PowerShell, you should try Windows' simple command-line. I didn't find out what caused this, but PowerShell seems to interpret some of Maven's parameters.

There is a CSS3 working draft that will (hopefully soon) allow you to write just:

p { text-indent: 200px hanging; }

Keep an eye on: https://developer.mozilla.org/en-US/docs/Web/CSS/text-indent

Always use UTC:

For example I have a schedule component that takes in one parameter DATETIME. When I call this using a GET verb I use the following format where my incoming parameter name is scheduleDate.

Example:

your initial request is "I have a large PDF file that is a floor map for a building. "

I am afraid to tell you this might be harder than you guess.

Cause the last known lib everyones use to parse pdf is smalot, and this one is known to encounter issue regarding large file.

Here too, Lookig for a real php lib to parse pdf, without any memory peak that need a php configuration to disable memory limit as lot of "developers" does (which I guess is really not advisable).

see this post for more details about smalot performance : https://github.com/smalot/pdfparser/issues/163

This one works for me. You can see this code on AccountController -> Register

var user = new JobUser { UserName = model.Email, Email = model.Email };
var result = await UserManager.CreateAsync(user, model.Password);
if (result.Succeeded)
{
    //add this to add role to user
     await UserManager.AddToRoleAsync(user.Id, "Name of your role");
}

but the role name must exist in your AspNetRoles table.

Indeed there is an API to search google programmatically. The API is called google custom search. For using this API, you will need an Google Developer API key and a cx key. A simple procedure for accessing google search from java program is explained in my blog.

Now dead, here is the Wayback Machine link.

Ok, I had the same problem.I came up with this solution.It worked for me the best.I did try atoi() but didn't work well for me.So here is my solution:

void splitInput(int arr[], int sizeArr, char num[])
{
    for(int i = 0; i < sizeArr; i++)
        // We are subtracting 48 because the numbers in ASCII starts at 48.
        arr[i] = (int)num[i] - 48;
}

if you want to execute tasks parallel,you need call the method executeOnExecutor(AsyncTask.THREAD_POOL_EXECUTOR, "your task name") after Android version of 3.0; but this method is not exist before Android 3.0 and after 1.6 because it execute parallel by itself, So I suggest you customize your own AsyncTask class in your project,to avoid throw exception in different Android version.

For java version above 1.8, Use below command to setup soapUI jar

java -jar --add-modules java.xml.bind --add-modules java.xml.ws <path for jar file+jar file name.jar>

Similar to Jeff's idea (untested):

find . -name * -print0 | grep -v "exclude" | xargs -0 -I {} cp -a {} destination/

for ip in `whois -h whois.radb.net '!gAS32934' | grep /`
do
  iptables -A FORWARD -p all -d $ip -j REJECT
done

After downloading the two zip files related to Oracle 11G R2. Create a folder in some directory (For say "Oracle_11G_R2"). Extract both zip files into the same folder "Oracle_11G_R2". And run setup.exe file present inside /database/setup.exe. It should run correctly now.

It does not natively, but you certainly can add this functionality

<script type="text/javascript">

String.prototype.regexIndexOf = function( pattern, startIndex )
{
    startIndex = startIndex || 0;
    var searchResult = this.substr( startIndex ).search( pattern );
    return ( -1 === searchResult ) ? -1 : searchResult + startIndex;
}

String.prototype.regexLastIndexOf = function( pattern, startIndex )
{
    startIndex = startIndex === undefined ? this.length : startIndex;
    var searchResult = this.substr( 0, startIndex ).reverse().regexIndexOf( pattern, 0 );
    return ( -1 === searchResult ) ? -1 : this.length - ++searchResult;
}

String.prototype.reverse = function()
{
    return this.split('').reverse().join('');
}

// Indexes 0123456789
var str = 'caabbccdda';

alert( [
        str.regexIndexOf( /[cd]/, 4 )
    ,   str.regexLastIndexOf( /[cd]/, 4 )
    ,   str.regexIndexOf( /[yz]/, 4 )
    ,   str.regexLastIndexOf( /[yz]/, 4 )
    ,   str.lastIndexOf( 'd', 4 )
    ,   str.regexLastIndexOf( /d/, 4 )
    ,   str.lastIndexOf( 'd' )
    ,   str.regexLastIndexOf( /d/ )
    ]
);

</script>

I didn't fully test these methods, but they seem to work so far.

It happend to me as well, I tried the above mentioned methods and nothing helped. Then the solution was to change the file via terminal, not GUI. I do not know why this worked but worked. After I edited the file via nano from terminal git recognized it as changed and i was able to add it and commit.

Try this:

using System.Diagnostics;
// Get call stack
StackTrace stackTrace = new StackTrace(); 
// Get calling method name
Console.WriteLine(stackTrace.GetFrame(1).GetMethod().Name);

one-liner:

(new System.Diagnostics.StackTrace()).GetFrame(1).GetMethod().Name

It is from Get Calling Method using Reflection [C#].

try,

str_list = " ".join([str(ele) for ele in numlist])

this statement will give you each element of your list in string format

print("The list now looks like [{0}]".format(str_list))

and,

change print(numlist.pop(2)+" has been removed") to

print("{0} has been removed".format(numlist.pop(2)))

as well.

The easiest way I find is to create a file "any_name.pth" and put it in your folder "\Lib\site-packages". You should find that folder wherever python is installed.

In that file, put a list of directories where you want to keep modules for importing. For instance, make a line in that file like this:

C:\Users\example...\example

You will be able to tell it works by running this in python:

import sys
for line in sys: print line

You will see your directory printed out, amongst others from where you can also import. Now you can import a "mymodule.py" file that sits in that directory as easily as:

import mymodule

This will not import subfolders. For that you could imagine creating a python script to create a .pth file containing all sub folders of a folder you define. Have it run at startup perhaps.

Using .apply() with a lambda conversion function also works in this case:

total_rows['ColumnID'] = total_rows['ColumnID'].apply(lambda x: str(x))

For entire dataframes you can use .applymap(). (but in any case probably .astype() is faster)

You can do it in two different ways.

Option 1: The -eq operator

>$a = "is"
>$b = "fission"
>$c = "is"
>$a -eq $c
True
>$a -eq $b
False

Option 2: The .Equals() method of the string object. Because strings in PowerShell are .Net System.String objects, any method of that object can be called directly.

>$a.equals($b)
False
>$a.equals($c)
True
>$a|get-member -membertype method

List of System.String methods follows.

Here is the answer I gave to a similar question, Simple, easy, works pretty good and does not require anything else than what you already have with Visual Studio.

As others have responded already Clean will remove all artifacts that are generated by the build. But it will leave behind everything else.

If you have some customizations in your MSBuild project this could spell trouble and leave behind stuff you would think it should have deleted.

You can circumvent this problem with a simple change to your .*proj by adding this somewhere near the end :

<Target Name="SpicNSpan"
        AfterTargets="Clean">
    <RemoveDir Directories="$(OUTDIR)"/>
</Target>

Which will remove everything in your bin folder of the current platform/configuration.

Not knowing time cost of shared_copy copy operation where atomic increment and decrement is in, I suffered from much higher CPU usage problem. I never expected atomic increment and decrement may take so much cost.

Following my test result, int32 atomic increment and decrement takes 2 or 40 times than non-atomic increment and decrement. I got it on 3GHz Core i7 with Windows 8.1. The former result comes out when no contention occurs, the latter when high possibility of contention occurs. I keep in mind that atomic operations are at last hardware based lock. Lock is lock. Bad to performance when contention occurs.

Experiencing this, I always use byref(const shared_ptr&) than byval(shared_ptr).

As I am not allowed to comment on user1908688's answer, here a hint for MariaDB users:

SELECT *
FROM (

     ) AS sub

Cardinality refers to the uniqueness of data contained in a column. If a column has a lot of duplicate data (e.g. a column that stores either "true" or "false"), it has low cardinality, but if the values are highly unique (e.g. Social Security numbers), it has high cardinality.

For eg.,. 2 fields are added in a model like below..

description = models.TextField(blank=True, null=True)
title = models.CharField(max_length=64, blank=True, null=True)

Below are the mysql queries executed when migrations are applied.

for TextField(description) the field is defined as a longtext

ALTER TABLE `sometable_sometable` ADD COLUMN `description` longtext NULL;

The maximum length of TextField of MySQL is 4GB according to string-type-overview.

for CharField(title) the max_length(required) is defined as varchar(64)

ALTER TABLE `sometable_sometable` ADD COLUMN `title` varchar(64) NULL;
ALTER TABLE `sometable_sometable` ALTER COLUMN `title` DROP DEFAULT;

Suppose your "Don't Check" list is on Sheet2 in cells A1:A100, say, and your current client IDs are in Sheet1 in Column A.

What you would do is:

1. Select the whole data table you want conditionally formatted in Sheet1
2. Click Conditional Formatting > New Rule > Use a Formula to determine which cells to format
3. In the formula bar, type in =ISNUMBER(MATCH($A1,Sheet2!$A$1:$A$100,0)) and select how you want those rows formatted

And that should do the trick.

Try:

return $this->sendRequest($uri);

Since PHP is not a pure Object-Orieneted language, it interprets sendRequest() as an attempt to invoke a globally defined function (just like nl2br() for example), but since your function is part of a class ('InstagramController'), you need to use $this to point the interpreter in the right direction.

Axios.post solution with IE and other browsers

I've found some incredible solutions here. But they frequently don't take into account problems with IE browser. Maybe it will save some time to somebody else.

 axios.post("/yourUrl"
                , data,
                {responseType: 'blob'}
            ).then(function (response) {
                    let fileName = response.headers["content-disposition"].split("filename=")[1];
                    if (window.navigator && window.navigator.msSaveOrOpenBlob) { // IE variant
                        window.navigator.msSaveOrOpenBlob(new Blob([response.data], {type: 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet'}),
                            fileName);
                    } else {
                        const url = window.URL.createObjectURL(new Blob([response.data], {type: 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet'}));
                        const link = document.createElement('a');
                        link.href = url;
                        link.setAttribute('download', response.headers["content-disposition"].split("filename=")[1]);
                        document.body.appendChild(link);
                        link.click();
                    }
                }
            );

example above is for excel files, but with little changes can be applied to any format.

And on server I've done this to send an excel file.

response.contentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"

response.addHeader(HttpHeaders.CONTENT_DISPOSITION, "attachment; filename=exceptions.xlsx")

$client = new \GuzzleHttp\Client();
$request = $client->post('http://demo.website.com/api', [
    'body' => json_encode($dataArray)
]);
$response = $request->getBody();

Add

openssl.cafile in php.ini file

In my case, the module containing the component using the *ngFor resulting in this error, was not included in the app.module.ts. Including it there in the imports array resolved the issue for me.

Sure, you could use HEREDOC, but as far as code readability goes it's not really any better than the first example, wrapping the string across multiple lines.

If you really want your multi-line string to look good and flow well with your code, I'd recommend concatenating strings together as such:

$text = "Hello, {$vars->name},\r\n\r\n"
    . "The second line starts two lines below.\r\n"
    . ".. Third line... etc";

This might be slightly slower than HEREDOC or a multi-line string, but it will flow well with your code's indentation and make it easier to read.

If your images are in a separate directory of your css file and you want the relative path begins from the root of your web site:

background-image: url('/Images/bgi.png');

You can use the WinSPC program. Its access to any server is pretty easy. The program gives its guide too. I hope it's helpfull.

The simplest modification (to the code in your question) is this:

    Range("A" & Rows.Count).End(xlUp).Select
    Selection.EntireRow.Delete

Which can be simplified to:

    Range("A" & Rows.Count).End(xlUp).EntireRow.Delete

How are you doing the compiling and linking? You'll need to specify both files, something like:

gcc testpoint.c point.c

...so that it knows to link the functions from both together. With the code as it's written right now, however, you'll then run into the opposite problem: multiple definitions of main. You'll need/want to eliminate one (undoubtedly the one in point.c).

In a larger program, you typically compile and link separately to avoid re-compiling anything that hasn't changed. You normally specify what needs to be done via a makefile, and use make to do the work. In this case you'd have something like this:

OBJS=testpoint.o point.o

testpoint.exe: $(OBJS)
    gcc $(OJBS)

The first is just a macro for the names of the object files. You get it expanded with $(OBJS). The second is a rule to tell make 1) that the executable depends on the object files, and 2) telling it how to create the executable when/if it's out of date compared to an object file.

Most versions of make (including the one in MinGW I'm pretty sure) have a built-in "implicit rule" to tell them how to create an object file from a C source file. It normally looks roughly like this:

.c.o:
    $(CC) -c $(CFLAGS) $<

This assumes the name of the C compiler is in a macro named CC (implicitly defined like CC=gcc) and allows you to specify any flags you care about in a macro named CFLAGS (e.g., CFLAGS=-O3 to turn on optimization) and $< is a special macro that expands to the name of the source file.

You typically store this in a file named Makefile, and to build your program, you just type make at the command line. It implicitly looks for a file named Makefile, and runs whatever rules it contains.

The good point of this is that make automatically looks at the timestamps on the files, so it will only re-compile the files that have changed since the last time you compiled them (i.e., files where the ".c" file has a more recent time-stamp than the matching ".o" file).

Also note that 1) there are lots of variations in how to use make when it comes to large projects, and 2) there are also lots of alternatives to make. I've only hit on the bare minimum of high points here.

I know your class is over, but in professional coding, let this be a lesson:

• "Deprecated" means "avoid use; it's going to be removed in the future"
• Deprecated things still work - just don't expect support or future-proofing
• If the requirement requires it, and you can't negotiate it away, just use the deprecated construct.
  
  • If you're really concerned, develop the alternative implementation on the side and keep it ready for the inevitable failure
  • Charge for the extra work now. By requesting a deprecated feature, they are asking you to double the work. You're going to see it again anyway, so might as well front-load it.
  • When the failure happens, let the interested party know that this was what you feared; that you prepared for it, but it'll take some time
  • Deploy your solution as quickly as you can (there will be bugs)

If you'd like to know how to sort a linked list without using standard Java libraries, I'd suggest looking at different algorithms yourself. Examples here show how to implement an insertion sort, another StackOverflow post shows a merge sort, and ehow even gives some examples on how to create a custom compare function in case you want to further customize your sort.

you can do something like adding a class to add border radius

HTML:

<a href="#" class="btn btn-default btn-circle"><i class="fa fa-user"></i></a>

CSS:

.btn-circle {
  width: 30px;
  height: 30px;
  text-align: center;
  padding: 6px 0;
  font-size: 12px;
  line-height: 1.42;
  border-radius: 15px;
}

in case you wanted to change dimension you need to change the font size or padding accordingly

NSLocalizedString() (and variants thereof) access the "AppleLanguages" key in NSUserDefaults to determine what the user's settings for preferred languages are. This returns an array of language codes, with the first one being the one set by the user for their phone, and the subsequent ones used as fallbacks if a resource is not available in the preferred language. (on the desktop, the user can specify multiple languages with a custom ordering in System Preferences)

You can override the global setting for your own application if you wish by using the setObject:forKey: method to set your own language list. This will take precedence over the globally set value and be returned to any code in your application that is performing localization. The code for this would look something like:

[[NSUserDefaults standardUserDefaults] setObject:[NSArray arrayWithObjects:@"de", @"en", @"fr", nil] forKey:@"AppleLanguages"];
[[NSUserDefaults standardUserDefaults] synchronize]; //to make the change immediate

This would make German the preferred language for your application, with English and French as fallbacks. You would want to call this sometime early in your application's startup. You can read more about language/locale preferences here: Internationalization Programming Topics: Getting the Current Language and Locale

To put breakpoints in your code, double click in the left margin on the line you want execution to stop on. You may alternatively put your cursor in this line and then press Shift+Ctrl+B.

To control execution use the Step Into, Step Over and Step Return buttons. They have the shortcuts F5, F6 and F7 respectively.

To allow execution to continue normally or until it hits the next breakpoint, hit the Resume button or F8.

For Python3 it is required to use BytesIO:

from io import BytesIO
from PIL import Image, ImageDraw

image = Image.new("RGB", (300, 50))
draw = ImageDraw.Draw(image)
draw.text((0, 0), "This text is drawn on image")

byte_io = BytesIO()

image.save(byte_io, 'PNG')

First, let's make some test data:

create table client (client_id integer not null primary key auto_increment,
                     name varchar(64));
create table portfolio (portfolio_id integer not null primary key auto_increment,
                        client_id integer references client.id,
                        cash decimal(10,2),
                        stocks decimal(10,2));
insert into client (name) values ('John Doe'), ('Jane Doe');
insert into portfolio (client_id, cash, stocks) values (1, 11.11, 22.22),
                                                       (1, 10.11, 23.22),
                                                       (2, 30.30, 40.40),
                                                       (2, 40.40, 50.50);

If you didn't need the portfolio ID, it would be easy:

select client_id, name, max(cash + stocks)
from client join portfolio using (client_id)
group by client_id

+-----------+----------+--------------------+
| client_id | name     | max(cash + stocks) |
+-----------+----------+--------------------+
|         1 | John Doe |              33.33 | 
|         2 | Jane Doe |              90.90 | 
+-----------+----------+--------------------+

Since you need the portfolio ID, things get more complicated. Let's do it in steps. First, we'll write a subquery that returns the maximal portfolio value for each client:

select client_id, max(cash + stocks) as maxtotal
from portfolio
group by client_id

+-----------+----------+
| client_id | maxtotal |
+-----------+----------+
|         1 |    33.33 | 
|         2 |    90.90 | 
+-----------+----------+

Then we'll query the portfolio table, but use a join to the previous subquery in order to keep only those portfolios the total value of which is the maximal for the client:

 select portfolio_id, cash + stocks from portfolio 
 join (select client_id, max(cash + stocks) as maxtotal 
       from portfolio
       group by client_id) as maxima
 using (client_id)
 where cash + stocks = maxtotal

+--------------+---------------+
| portfolio_id | cash + stocks |
+--------------+---------------+
|            5 |         33.33 | 
|            6 |         33.33 | 
|            8 |         90.90 | 
+--------------+---------------+

Finally, we can join to the client table (as you did) in order to include the name of each client:

select client_id, name, portfolio_id, cash + stocks
from client
join portfolio using (client_id)
join (select client_id, max(cash + stocks) as maxtotal
      from portfolio 
      group by client_id) as maxima
using (client_id)
where cash + stocks = maxtotal

+-----------+----------+--------------+---------------+
| client_id | name     | portfolio_id | cash + stocks |
+-----------+----------+--------------+---------------+
|         1 | John Doe |            5 |         33.33 | 
|         1 | John Doe |            6 |         33.33 | 
|         2 | Jane Doe |            8 |         90.90 | 
+-----------+----------+--------------+---------------+

Note that this returns two rows for John Doe because he has two portfolios with the exact same total value. To avoid this and pick an arbitrary top portfolio, tag on a GROUP BY clause:

select client_id, name, portfolio_id, cash + stocks
from client
join portfolio using (client_id)
join (select client_id, max(cash + stocks) as maxtotal
      from portfolio 
      group by client_id) as maxima
using (client_id)
where cash + stocks = maxtotal
group by client_id, cash + stocks

+-----------+----------+--------------+---------------+
| client_id | name     | portfolio_id | cash + stocks |
+-----------+----------+--------------+---------------+
|         1 | John Doe |            5 |         33.33 | 
|         2 | Jane Doe |            8 |         90.90 | 
+-----------+----------+--------------+---------------+

You do not specify why you think it is wrong but I can se two dangers:

BETWEEN can be implemented differently in different databases sometimes it is including the border values and sometimes excluding, resulting in that 1 and 31 of january would end up NOTHING. You should test how you database does this.

Also, if RATE_DATE contains hours also 2010-01-31 might be translated to 2010-01-31 00:00 which also would exclude any row with an hour other that 00:00.

The crux of the solution is setting

CURLOPT_RETURNTRANSFER => true

then

$response = curl_exec($ch);

CURLOPT_RETURNTRANSFER tells PHP to store the response in a variable instead of printing it to the page, so $response will contain your response. Here's your most basic working code (I think, didn't test it):

// init curl object        
$ch = curl_init();

// define options
$optArray = array(
    CURLOPT_URL => 'http://www.google.com',
    CURLOPT_RETURNTRANSFER => true
);

// apply those options
curl_setopt_array($ch, $optArray);

// execute request and get response
$result = curl_exec($ch);

In Java 8 you can use Files.write() method with two arguments: Path and List<String>, something like this:

List<String> clubNames = clubs.stream()
    .map(Club::getName)
    .collect(Collectors.toList())

try {
    Files.write(Paths.get(fileName), clubNames);
} catch (IOException e) {
    log.error("Unable to write out names", e);
}

This is the normal behavior and the reason is that your sqlCommandHandlerService.persist method needs a TX when being executed (because it is marked with @Transactional annotation). But when it is called inside processNextRegistrationMessage, because there is a TX available, the container doesn't create a new one and uses existing TX. So if any exception occurs in sqlCommandHandlerService.persist method, it causes TX to be set to rollBackOnly (even if you catch the exception in the caller and ignore it).

To overcome this you can use propagation levels for transactions. Have a look at this to find out which propagation best suits your requirements.

Update; Read this!

Well after a colleague came to me with a couple of questions about a similar situation, I feel this needs a bit of clarification.
Although propagations solve such issues, you should be VERY careful about using them and do not use them unless you ABSOLUTELY understand what they mean and how they work. You may end up persisting some data and rolling back some others where you don't expect them to work that way and things can go horribly wrong.

It's perhaps surprising to note that you don't need to know how many days or months there are in a year or how many days are in those months, likewise, you don't need to know about leap years, leap seconds, or any of that stuff using this simple, 100% accurate method:

public static int age(Date birthday, Date date) {
    DateFormat formatter = new SimpleDateFormat("yyyyMMdd");
    int d1 = Integer.parseInt(formatter.format(birthday));
    int d2 = Integer.parseInt(formatter.format(date));
    int age = (d2-d1)/10000;
    return age;
}

Also can be done in this way:

Object.entries(obj).length

For example:

let obj = { a: 1, b: 2, };
console.log(Object.entries(obj).length); //=> 2
// Object.entries(obj) => [ [ 'a', 1 ], [ 'b', 2 ] ]

Not quite an answer (not “using Developer Tools”), but there is a third-party tool for it: IECookiesView from NirSoft. Hope this helps someone.

There is a way to skip the errors inside the code and go on with the loop anyway, hope it helps:

Sub new1()

Dim wsFunc As WorksheetFunction: Set wsFunc = Application.WorksheetFunction
Dim ws As Worksheet: Set ws = Sheets(1)
Dim rngLook As Range: Set rngLook = ws.Range("A:M")

currName = "Example"
On Error Resume Next ''if error, the code will go on anyway
cellNum = wsFunc.VLookup(currName, rngLook, 13, 0)

If Err.Number <> 0 Then
''error appeared
    MsgBox "currName not found" ''optional, no need to do anything
End If

On Error GoTo 0 ''no error, coming back to default conditions

End Sub

You can use setInterval:

var timer = setInterval( myFunction, 1000);

Just declare your function as myFunction or some other name, and then don't bind it to $('.more')'s live event.

Here's another way of getting a Bash array with the example JSON given by @anubhava in his answer:

arr=($(jq --raw-output 'keys_unsorted | @sh' file.json))

echo ${arr[0]}    # 'Archiver-Version'
echo ${arr[1]}    # 'Build-Id'
echo ${arr[2]}    # 'Build-Jdk'

class Program
{
     public static EventHandler AsyncHandler;
     static void Main(string[] args)
     {
        AsyncHandler+= async (sender, eventArgs) => { await AsyncMain(); };
        AsyncHandler?.Invoke(null, null);
     }

     private async Task AsyncMain()
     {
        //Your Async Code
     }
}

Why not:

template<typename K, typename V>
std::vector<V> MapValuesAsVector(const std::map<K, V>& map)
{
   std::vector<V> vec;
   vec.reserve(map.size());
   std::for_each(std::begin(map), std::end(map),
        [&vec] (const std::map<K, V>::value_type& entry) 
        {
            vec.push_back(entry.second);
        });
    return vec;
}

usage:

auto vec = MapValuesAsVector(anymap);

This class is used to instantiate layout XML file into its corresponding View objects. It is never be used directly -- use getLayoutInflater() or getSystemService(String) to retrieve a standard LayoutInflater instance that is already hooked up to the current context and correctly configured for the device you are running on. For example:

LayoutInflater inflater = (LayoutInflater)context.getSystemService
      (Context.LAYOUT_INFLATER_SERVICE);

The individual alphabets or symbols residing in a single cell can be inserted into different cells in different columns by the following code:

For i = 1 To Len(Cells(1, 1))
Cells(2, i) = Mid(Cells(1, 1), i, 1)
Next

If you do not want the symbols like colon to be inserted put an if condition in the loop.

Use the Array.prototype.push method to append values to the end of an array:

// initialize array
var arr = [
  "Hi",
  "Hello",
  "Bonjour"
];

// append new value to the array
arr.push("Hola");

console.log(arr);

You can use the push() function to append more than one value to an array in a single call:

// initialize array
var arr = ["Hi", "Hello", "Bonjour", "Hola"];

// append multiple values to the array
arr.push("Salut", "Hey");

// display all values
for (var i = 0; i < arr.length; i++) {
  console.log(arr[i]);
}

Update

If you want to add the items of one array to another array, you can use firstArray.concat(secondArray):

var arr = [
  "apple",
  "banana",
  "cherry"
];

arr = arr.concat([
  "dragonfruit",
  "elderberry",
  "fig"
]);

console.log(arr);

Update

Just an addition to this answer if you want to prepend any value to the start of an array (i.e. first index) then you can use Array.prototype.unshift for this purpose.

var arr = [1, 2, 3];
arr.unshift(0);
console.log(arr);

It also supports appending multiple values at once just like push.

Update

Another way with ES6 syntax is to return a new array with the spread syntax. This leaves the original array unchanged, but returns a new array with new items appended, compliant with the spirit of functional programming.

const arr = [
  "Hi",
  "Hello",
  "Bonjour",
];

const newArr = [
  ...arr,
  "Salut",
];

console.log(newArr);

With jQuery you can use

$('#main-div .specific-class').length

otherwise in VanillaJS (from IE8 included) you may use

document.querySelectorAll('#main-div .specific-class').length;

Based on the the8472 answer and https://developer.mozilla.org/en-US/docs/Web/API/Element/matches here is cross-platform 2017 solution:

if (!Element.prototype.matches) {
    Element.prototype.matches =
        Element.prototype.matchesSelector ||
        Element.prototype.mozMatchesSelector ||
        Element.prototype.msMatchesSelector ||
        Element.prototype.oMatchesSelector ||
        Element.prototype.webkitMatchesSelector ||
        function(s) {
            var matches = (this.document || this.ownerDocument).querySelectorAll(s),
                i = matches.length;
            while (--i >= 0 && matches.item(i) !== this) {}
            return i > -1;
        };
}

function findAncestor(el, sel) {
    if (typeof el.closest === 'function') {
        return el.closest(sel) || null;
    }
    while (el) {
        if (el.matches(sel)) {
            return el;
        }
        el = el.parentElement;
    }
    return null;
}

First check the value of session.save_path using ini_get('session.save_path') or phpinfo(). If that is non-empty, then it will show where the session files are saved. In many scenarios it is empty by default, in which case read on:

On Ubuntu or Debian machines, if session.save_path is not set, then session files are saved in /var/lib/php5.

On RHEL and CentOS systems, if session.save_path is not set, session files will be saved in /var/lib/php/session

I think that if you compile PHP from source, then when session.save_path is not set, session files will be saved in /tmp (I have not tested this myself though).

Yes, simply set it to another value:

$_POST['text'] = 'another value';

This will override the previous value corresponding to text key of the array. The $_POST is superglobal associative array and you can change the values like a normal PHP array.

Caution: This change is only visible within the same PHP execution scope. Once the execution is complete and the page has loaded, the $_POST array is cleared. A new form submission will generate a new $_POST array.

If you want to persist the value across form submissions, you will need to put it in the form as an input tag's value attribute or retrieve it from a data store.

You need to add the package containing the executable pg_config.

A prior answer should have details you need: pg_config executable not found

(123456789).toString(10).split("")

^^ this will return an array of strings

(123456789).toString(10).split("").map(function(t){return parseInt(t)})

^^ this will return an array of ints

I think the result for those two should always be the same. The difference is that you need an instance of the class to use isInstance but just the Class object to use isAssignableFrom.

For POD class members, it makes no difference, it's just a matter of style. For class members which are classes, then it avoids an unnecessary call to a default constructor. Consider:

class A
{
public:
    A() { x = 0; }
    A(int x_) { x = x_; }
    int x;
};

class B
{
public:
    B()
    {
        a.x = 3;
    }
private:
    A a;
};

In this case, the constructor for B will call the default constructor for A, and then initialize a.x to 3. A better way would be for B's constructor to directly call A's constructor in the initializer list:

B()
  : a(3)
{
}

This would only call A's A(int) constructor and not its default constructor. In this example, the difference is negligible, but imagine if you will that A's default constructor did more, such as allocating memory or opening files. You wouldn't want to do that unnecessarily.

Furthermore, if a class doesn't have a default constructor, or you have a const member variable, you must use an initializer list:

class A
{
public:
    A(int x_) { x = x_; }
    int x;
};

class B
{
public:
    B() : a(3), y(2)  // 'a' and 'y' MUST be initialized in an initializer list;
    {                 // it is an error not to do so
    }
private:
    A a;
    const int y;
};

You can expose the service in two different endpoints. the SOAP one can use the binding that support SOAP e.g. basicHttpBinding, the RESTful one can use the webHttpBinding. I assume your REST service will be in JSON, in that case, you need to configure the two endpoints with the following behaviour configuration

<endpointBehaviors>
  <behavior name="jsonBehavior">
    <enableWebScript/>
  </behavior>
</endpointBehaviors>

An example of endpoint configuration in your scenario is

<services>
  <service name="TestService">
    <endpoint address="soap" binding="basicHttpBinding" contract="ITestService"/>
    <endpoint address="json" binding="webHttpBinding"  behaviorConfiguration="jsonBehavior" contract="ITestService"/>
  </service>
</services>

so, the service will be available at

• http://www.example.com/soap
• http://www.example.com/json

Apply [WebGet] to the operation contract to make it RESTful. e.g.

public interface ITestService
{
   [OperationContract]
   [WebGet]
   string HelloWorld(string text)
}

Note, if the REST service is not in JSON, parameters of the operations can not contain complex type.

Reply to the post for SOAP and RESTful POX(XML)

For plain old XML as return format, this is an example that would work both for SOAP and XML.

[ServiceContract(Namespace = "http://test")]
public interface ITestService
{
    [OperationContract]
    [WebGet(UriTemplate = "accounts/{id}")]
    Account[] GetAccount(string id);
}

POX behavior for REST Plain Old XML

<behavior name="poxBehavior">
  <webHttp/>
</behavior>

Endpoints

<services>
  <service name="TestService">
    <endpoint address="soap" binding="basicHttpBinding" contract="ITestService"/>
    <endpoint address="xml" binding="webHttpBinding"  behaviorConfiguration="poxBehavior" contract="ITestService"/>
  </service>
</services>

Service will be available at

• http://www.example.com/soap
• http://www.example.com/xml

REST request try it in browser,

http://www.example.com/xml/accounts/A123

SOAP request client endpoint configuration for SOAP service after adding the service reference,

  <client>
    <endpoint address="http://www.example.com/soap" binding="basicHttpBinding"
      contract="ITestService" name="BasicHttpBinding_ITestService" />
  </client>

in C#

TestServiceClient client = new TestServiceClient();
client.GetAccount("A123");

Another way of doing it is to expose two different service contract and each one with specific configuration. This may generate some duplicates at code level, however at the end of the day, you want to make it working.

One option would be combining use of CASE..WHEN statement is redundant within an aggregation for MySQL Database, and considering the needed query generation dynamically along with getting proper column title for the result set as in the following code block :

SET @sql = NULL;

SELECT GROUP_CONCAT(
             CONCAT('SUM( `action` = ''', action, '''',pc0,' ) AS ',action,pc1)
       )
  INTO @sql
  FROM 
  ( 
   SELECT DISTINCT `action`, 
          IF(`pagecount` IS NULL,'',CONCAT('page',`pagecount`)) AS pc1,
          IF(`pagecount` IS NULL,'',CONCAT(' AND `pagecount` = ', pagecount, '')) AS pc0
     FROM `tab` 
    ORDER BY CONCAT(action,pc0) 
  ) t;

SET @sql = CONCAT('SELECT company_name,',@sql,' FROM `tab` GROUP BY company_name'); 
SELECT @sql; 

PREPARE stmt FROM @sql;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;

In my opinion i had missed to map my local branch with remote repo. i did below and it worked fine.

git checkout master
git remote add origin https://github.com/yourrepo/project.git
git push -u origin master
git pull
git merge myBranch1FromMain

Use:

 System.out.println("Current date in Date Format: " + sdf.format(date));

So, let's say you have this table:

CREATE TABLE YourTable(Col1 VARCHAR(10))

And you want to change Col1 to VARCHAR(20). What you need to do is this:

ALTER TABLE YourTable
ALTER COLUMN Col1 VARCHAR(20)

That'll work without problems since the length of the column got bigger. If you wanted to change it to VARCHAR(5), then you'll first gonna need to make sure that there are not values with more chars on your column, otherwise that ALTER TABLE will fail.

You get this error if you have constrained T to being a class

I've added some usability to the function from the answer by @Octopus, for debugging purposes.

void MatType( Mat inputMat )
{
    int inttype = inputMat.type();

    string r, a;
    uchar depth = inttype & CV_MAT_DEPTH_MASK;
    uchar chans = 1 + (inttype >> CV_CN_SHIFT);
    switch ( depth ) {
        case CV_8U:  r = "8U";   a = "Mat.at<uchar>(y,x)"; break;  
        case CV_8S:  r = "8S";   a = "Mat.at<schar>(y,x)"; break;  
        case CV_16U: r = "16U";  a = "Mat.at<ushort>(y,x)"; break; 
        case CV_16S: r = "16S";  a = "Mat.at<short>(y,x)"; break; 
        case CV_32S: r = "32S";  a = "Mat.at<int>(y,x)"; break; 
        case CV_32F: r = "32F";  a = "Mat.at<float>(y,x)"; break; 
        case CV_64F: r = "64F";  a = "Mat.at<double>(y,x)"; break; 
        default:     r = "User"; a = "Mat.at<UKNOWN>(y,x)"; break; 
    }   
    r += "C";
    r += (chans+'0');
    cout << "Mat is of type " << r << " and should be accessed with " << a << endl;

}

You can check if the mysqli libraries are present by executing this code:

if (!function_exists('mysqli_init') && !extension_loaded('mysqli')) {
    echo 'We don\'t have mysqli!!!';
} else {
    echo 'Phew we have it!';
}

Please Try this.

I created a button...

This is where you've gone wrong. You haven't created a button, you've created an anchor element. If you had used a button element instead, you wouldn't have this problem:

<button type="button" data-toggle="modal" data-target="#myModal" data-role="disabled">
    Connect
</button>

If you are going to continue using an a element instead, at the very least you should give it a role attribute set to "button" and drop the href attribute altogether:

<a role="button" ...>

Once you've done that you can introduce a piece of JavaScript which calls event.preventDefault() - here with event being your click event.

Try to install the update 1 package, link. I have had the same problem and solved when I installed the update.

The easiest way to do it is leaving action blank action="" or omitting it completely from the form tag, however it is bad practice (if at all you care about it).

Incase you do care about it, the best you can do is:

<form name="form1" id="mainForm" method="post" enctype="multipart/form-data" action="<?php echo($_SERVER['PHP_SELF'] . http_build_query($_GET));?>">

The best thing about using this is that even arrays are converted so no need to do anything else for any kind of data.

location ~ /issue([0-9]+) {
    return 301 http://example.com/shop/issues/custom_isse_name$1;
}

1) You can set root password by invoking MySQL console. It is located in

C:\wamp\bin\mysql\mysql5.1.53\bin by default.

Get to the directory and type MySQL. then set the password as follows..

    > SET PASSWORD FOR root@localhost = PASSWORD('new-password');

2) You can configure wamp's phpmyadmin application for root user by editing

C:\wamp\apps\phpmyadmin3.3.9\config.inc.php 

Note :- if you are using xampp then , file will be located at

C:\xampp\phpMyadmin\config.inc.php

It looks like this:

        $cfg['Servers'][$i]['verbose'] = 'localhost';
        $cfg['Servers'][$i]['host'] = 'localhost';
        $cfg['Servers'][$i]['port'] = '';
        $cfg['Servers'][$i]['socket'] = '';
        $cfg['Servers'][$i]['connect_type'] = 'tcp';
        $cfg['Servers'][$i]['extension'] = 'mysqli';
        $cfg['Servers'][$i]['auth_type'] = 'config';
        $cfg['Servers'][$i]['user'] = 'root';
        $cfg['Servers'][$i]['password'] = 'YOURPASSWORD';
        $cfg['Servers'][$i]['AllowNoPassword'] = false;

The error "Access denied for user 'root@localhost' (using password:NO)" will be resolved when you set $cfg['Servers'][$i]['AllowNoPassword'] to false

If you priviously changed the password for 'root@localhost', then you have to do 2 things to solve the error "Access denided for user 'root@localhost'":

1. if ['password'] have a empty quotes like ' ' then put your password between quotes.
2. change the (using password:NO) to (using password:YES)

This will resolve the error.

Note: phpmyadmin is a separate tool which comes with wamp. It just provide a interface to MySQL. if you change my sql root's password, then you should change the phpmyadmin configurations. Usually phpmyadmin is configured to root user.

From here:

// when the DOM is ready
$(function () {
  var img = new Image();
  // wrap our new image in jQuery, then:
  $(img)
    // once the image has loaded, execute this code
    .load(function () {
      // set the image hidden by default    
      $(this).hide();
      // with the holding div #loader, apply:
      $('#loader')
        // remove the loading class (so no background spinner), 
        .removeClass('loading')
        // then insert our image
        .append(this);
      // fade our image in to create a nice effect
      $(this).fadeIn();
    })
    // if there was an error loading the image, react accordingly
    .error(function () {
      // notify the user that the image could not be loaded
    })
    // *finally*, set the src attribute of the new image to our image
    .attr('src', 'images/headshot.jpg');
});

You need to create a comparator. I am not sure why each value needs its own map but here is what the comparator would look like:

class ListMapComparator implements Comparator {
    public int compare(Object obj1, Object obj2) {
         Map<String, String> test1 = (Map<String, String>) obj1;
         Map<String, String> test2 = (Map<String, String>) obj2;
         return test1.get("name").compareTo(test2.get("name"));
    }
}

You can see it working with your above example with this:

public class MapSort {
    public List<Map<String, String>> testMap() {
         List<Map<String, String>> list = new ArrayList<Map<String, String>>();
         Map<String, String> myMap1 = new HashMap<String, String>();
         myMap1.put("name", "Josh");
         Map<String, String> myMap2 = new HashMap<String, String>();
         myMap2.put("name", "Anna");

         Map<String, String> myMap3 = new HashMap<String, String>();
         myMap3.put("name", "Bernie");


         list.add(myMap1);
         list.add(myMap2);
         list.add(myMap3);

         return list;
    }

    public static void main(String[] args) {
         MapSort ms = new MapSort();
         List<Map<String, String>> testMap = ms.testMap();
         System.out.println("Before Sort: " + testMap);
         Collections.sort(testMap, new ListMapComparator());
         System.out.println("After Sort: " + testMap);
    }
}

You will have some type safe warnings because I did not worry about these. Hope that helps.

I see users in comments wondering how to disable cell editing while allowing row deletion : I managed to do this by setting all columns individually to read only, instead of the DataGrid itself.

<DataGrid IsReadOnly="False">
    <DataGrid.Columns>
        <DataGridTextColumn IsReadOnly="True"/>
        <DataGridTextColumn IsReadOnly="True"/>
    </DataGrid.Columns>
</DataGrid>

Perhaps you were looking at the space complexity? That is O(n). The other complexities are as expected on the hash table entry. The search complexity approaches O(1) as the number of buckets increases. If at the worst case you have only one bucket in the hash table, then the search complexity is O(n).

Edit in response to comment I don't think it is correct to say O(1) is the average case. It really is (as the wikipedia page says) O(1+n/k) where K is the hash table size. If K is large enough, then the result is effectively O(1). But suppose K is 10 and N is 100. In that case each bucket will have on average 10 entries, so the search time is definitely not O(1); it is a linear search through up to 10 entries.

Looks like PostgreSQL supports a schema object called a rule.

http://www.postgresql.org/docs/current/static/rules-update.html

You could create a rule ON INSERT for a given table, making it do NOTHING if a row exists with the given primary key value, or else making it do an UPDATE instead of the INSERT if a row exists with the given primary key value.

I haven't tried this myself, so I can't speak from experience or offer an example.

     Stream<Integer> stream = Stream.of(1, 2, 3, 4, 5, 6);

     Integer[] integers = stream.toArray(it->new Integer[it]);

npm update: install and update with latest node modules which are in package.json

npm install: install node modules which are defined in package.json(without update)

what about this:

divH = divW = 0;
jQuery(document).ready(function(){
    divW = jQuery("div").width();
    divH = jQuery("div").height();
});
function checkResize(){
    var w = jQuery("div").width();
    var h = jQuery("div").height();
    if (w != divW || h != divH) {
        /*what ever*/
        divH = h;
        divW = w;
    }
}
jQuery(window).resize(checkResize);
var timer = setInterval(checkResize, 1000);

BTW I suggest you to add an id to the div and change the $("div") to $("#yourid"), it's gonna be faster, and it won't break when later you add other divs

Determine if 2 lists have the same elements, regardless of order?

Inferring from your example:

x = ['a', 'b']
y = ['b', 'a']

that the elements of the lists won't be repeated (they are unique) as well as hashable (which strings and other certain immutable python objects are), the most direct and computationally efficient answer uses Python's builtin sets, (which are semantically like mathematical sets you may have learned about in school).

set(x) == set(y) # prefer this if elements are hashable

In the case that the elements are hashable, but non-unique, the collections.Counter also works semantically as a multiset, but it is far slower:

from collections import Counter
Counter(x) == Counter(y)

Prefer to use sorted:

sorted(x) == sorted(y) 

if the elements are orderable. This would account for non-unique or non-hashable circumstances, but this could be much slower than using sets.

Empirical Experiment

An empirical experiment concludes that one should prefer set, then sorted. Only opt for Counter if you need other things like counts or further usage as a multiset.

First setup:

import timeit
import random
from collections import Counter

data = [str(random.randint(0, 100000)) for i in xrange(100)]
data2 = data[:]     # copy the list into a new one

def sets_equal(): 
    return set(data) == set(data2)

def counters_equal(): 
    return Counter(data) == Counter(data2)

def sorted_lists_equal(): 
    return sorted(data) == sorted(data2)

And testing:

>>> min(timeit.repeat(sets_equal))
13.976069927215576
>>> min(timeit.repeat(counters_equal))
73.17287588119507
>>> min(timeit.repeat(sorted_lists_equal))
36.177085876464844

So we see that comparing sets is the fastest solution, and comparing sorted lists is second fastest.

VMDK is a virtual disk file, what you need is a VMX file. Cruise on over to EasyVMX and have it create one for you, then just replace the VMDK file it gives you with the Cnrome OS one.

EasyVMX is good since VMWare Player has no VM creation stuff in it (at least in version 2, not sure about 3). You had to use one of VMWare's other products to do that.

Since I am sorting alphabetically on a string field and NOT by ID, the Count(*) and DCOUNT() approaches didn't work for me. My solution was to write a function that returns the Row Number:

Option Compare Database
Option Explicit
Private Rst As Recordset

Public Function GetRowNum(ID As Long) As Long
  If Rst Is Nothing Then
    Set Rst = CurrentDb.OpenRecordset("SELECT ID FROM FileList ORDER BY RealName")
  End If
  Rst.FindFirst "ID=" & ID
  GetRowNum = Rst.AbsolutePosition + 1
' Release the Rst 1 sec after it's last use
'------------------------------------------
  SetTimer Application.hWndAccessApp, 1, 1000, AddressOf ReleaseRst  
End Function


Private Sub ReleaseRst(ByVal hWnd As LongPtr, ByVal uMsg As Long, ByVal nIDEEvent As Long, ByVal dwTime As Long)
  KillTimer Application.hWndAccessApp, 1 
  Set Rst = Nothing
End Sub

Just to add on [This line perfectly work in Asp.net& find web-control Fields in jason Eg:<%Fieldname%>]

 data: "{LocationName:'" + document.getElementById('<%=txtLocationName.ClientID%>').value + "',AreaID:'" + document.getElementById('<%=DropDownArea.ClientID%>').value + "'}",

val timer = Timer()
timer.schedule(timerTask { nextScreen() }, 3000)

If you're treating it as a tuple (see section 3.3.3 of the language spec), then:

var t:[number, string] = [1, "message"]

or

interface NumberStringTuple extends Array<string|number>{0:number; 1:string}
var t:NumberStringTuple = [1, "message"];

You have a couple options. You can include a callback as a second argument, which will be invoked with any error message and the object. This example is straight from the AWS documentation:

s3.getObject(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Alternatively, you can convert the output to a stream. There's also an example in the AWS documentation:

var s3 = new AWS.S3({apiVersion: '2006-03-01'});
var params = {Bucket: 'myBucket', Key: 'myImageFile.jpg'};
var file = require('fs').createWriteStream('/path/to/file.jpg');
s3.getObject(params).createReadStream().pipe(file);

If you are targeting SDK > 21 (lollipop or 5.0) use

context.getDrawable(R.drawable.your_drawable_name)

See docs

Make sure your escaping the HTML characters

E.g.

// Always check an input variable is set before you use it
if (isset($_POST['contact_list'])) {
    // Escape any html characters
    echo htmlentities($_POST['contact_list']);
}

This would occur because of the angle brackets and the browser thinking they are tags.

See: http://php.net/manual/en/function.htmlentities.php

Example 4 columns of span3. For other span widths use new width = old width + gutter size. Use media queries to make it responsive.

css:

    <style type="text/css">
    @media (min-width: 1200px) 
    {   
        .nogutter .span3
        {
            margin-left: 0px; width:300px;
        }   
    }
    @media (min-width: 980px) and (max-width: 1199px) 
    { 
        .nogutter .span3
        {
            margin-left: 0px; width:240px;
        }   
    }
    @media (min-width: 768px) and (max-width: 979px) 
    { 
        .nogutter .span3
        {   
            margin-left: 0px; width:186px;
        }   
    }
    </style>

html:

<div class="container">
<div class="row">
  <div class="span3" style="background-color:red;">...</div>
  <div class="span3" style="background-color:red;">...</div>
  <div class="span3" style="background-color:red;">...</div>
  <div class="span3" style="background-color:red;">...</div>
</div>
<br>
<div class="row nogutter">
  <div class="span3" style="background-color:red;">...</div>
  <div class="span3" style="background-color:red;">...</div>
  <div class="span3" style="background-color:red;">...</div>
  <div class="span3" style="background-color:red;">...</div>
</div> 
</div>

update: or split a span12 div in 100/numberofcolumns % width parts floating left:

<div class="row">
  <div class="span12">
    <div style="background-color:green;width:25%;float:left;">...</div>
  <div style="background-color:yellow;width:25%;float:left;">...</div>
  <div style="background-color:red;width:25%;float:left;">...</div>
  <div style="background-color:blue;width:25%;float:left;">...</div>
  </div>
</div>  

For both solutions see: http://bootply.com/61557

In addition to the link provided by Floremin, which clears text selection using JavaScript to "clear" the selection, you can also use pure CSS to accomplish this. The CSS is here...

.noSelect {
    -webkit-touch-callout: none;
    -webkit-user-select: none;
    -khtml-user-select: none;
    -moz-user-select: none;
    -ms-user-select: none;
    user-select: none;
}

Simply add the class="noSelect" attribute to the element you wish to apply this class to. I would highly recommend giving this CSS solution a try. Nothing wrong with using the JavaScript, I just believe this could potentially be easier, and clean things up a little bit in your code.

For chrome on android -webkit-tap-highlight-color: transparent; is an additional rule you may want to experiment with for support in Android.

To disable bundling and minification just put this your .aspx file (this will disable optimization even if debug=true in web.config)

vb.net:

System.Web.Optimization.BundleTable.EnableOptimizations = false

c#.net

System.Web.Optimization.BundleTable.EnableOptimizations = false;

If you put EnableOptimizations = true this will bundle and minify even if debug=true in web.config

It's sort of arbitrary which of the terms to use. It could have been either way. Perhaps the language designers thought of "extends" as the most fundamental term, and "implements" as the special case for interfaces.

But I think implements would make slightly more sense. I think that communicates more that the parameter types don't have to be in an inheritance relationship, they can be in any kind of subtype relationship.

The Java Glossary expresses a similar view.

A more generic approach

To simplify this approach an "id" interface is used

public interface IGuidKey
{
    Guid Id { get; set; }
}

The helper method

public static void Modify<T>(this DbSet<T> set, Guid id, Action<T> func)
    where T : class, IGuidKey, new()
{
    var target = new T
    {
        Id = id
    };
    var entry = set.Attach(target);
    func(target);
    foreach (var property in entry.Properties)
    {
        var original = property.OriginalValue;
        var current = property.CurrentValue;

        if (ReferenceEquals(original, current))
        {
            continue;
        }

        if (original == null)
        {
            property.IsModified = true;
            continue;
        }

        var propertyIsModified = !original.Equals(current);
        property.IsModified = propertyIsModified;
    }
}

Usage

dbContext.Operations.Modify(id, x => { x.Title = "aaa"; });

If you want to use your custom pipe in your components, you can add

@Injectable({
  providedIn: 'root'
})

annotation to your custom pipe. Then, you can use it as a service

JDBC uses a so-called "connection URL", so you can escape "+" by "%2B", that is

useTimezone=true&serverTimezone=GMT%2B8

a {
    color: orange !important;
}

!important has the effect that the property in question cannot be overridden unless another !important is used. It is generally considered bad practice to use !important unless absolutely necessary; however, I can't think of any other way of ‘disabling’ :visited using CSS only.

If you pass the name of an array as an argument to a function, it is treated as if you had passed the address of the array. So &s and s are identical arguments. See K&R 5.3. &s[0] is the same as &s, since it takes the address of the first element of the array, which is the same as taking the address of the array itself.

For all the others, although all pointers are essentially memory locations they are still typed, and the compiler will warn about assigning one type of pointer to another.

• void* p; says p is a memory address, but I don't know what's in the memory
• char* s; says s is a memory address, and the first byte contains a character
• char** ps; says ps is a memory address, and the four bytes there (for a 32-bit system) contain a pointer of type char*.

cf http://www.oberon2005.ru/paper/kr_c.pdf (e-book version of K&R)

Technically, and from Comintern's accepted workaround, I believe you actually want to Delete all the Cells in the Sheet. Which removes Formatting (See footnote for exceptions), etc. as well as the Cells Contents. I.e. Sheets("Zeroes").Cells.Delete

Combined also with UsedRange, ScreenUpdating and Calculation skipping it should be nearly intantaneous:

Sub DeleteCells ()
    Application.Calculation = XlManual
    Application.ScreenUpdating = False
    Sheets("Zeroes").UsedRange.Delete
    Application.ScreenUpdating = True
    Application.Calculation = xlAutomatic
End Sub

Or if you prefer to respect the Calculation State Excel is currently in:

Sub DeleteCells ()
    Dim SaveCalcState
    SaveCalcState = Application.Calculation
    Application.Calculation = XlManual
    Application.ScreenUpdating = False
    Sheets("Zeroes").UsedRange.Delete
    Application.ScreenUpdating = True
    Application.Calculation = SaveCalcState
End Sub

Footnote: If formatting was applied for an Entire Column, then it is not deleted. This includes Font Colour, Fill Colour and Borders, the Format Category (like General, Date, Text, Etc.) and perhaps other properties too, but

Conditional formatting IS deleted, as is Entire Row formatting.

(Entire Column formatting is quite useful if you are importing raw data repeatedly to a sheet as it will conform to the Formats originally applied if a simple Paste-Values-Only type import is done.)

@RequestBody MultipartFile[] submissions

should be

@RequestParam("file") MultipartFile[] submissions

The files are not the request body, they are part of it and there is no built-in HttpMessageConverter that can convert the request to an array of MultiPartFile.

You can also replace HttpServletRequest with MultipartHttpServletRequest, which gives you access to the headers of the individual parts.

app:tabIndicatorColor="@android:color/white"

You can use jquery.serializeJSON to do this.

Try Converting C++ enums to strings. The comments have improvements that solve the problem when enum items have arbitrary values.

Create a Random object with a seed and get the array random by doing:

public static final int ARRAY_LENGTH = 20;

byte[] byteArray = new byte[ARRAY_LENGTH];
new Random(System.currentTimeMillis()).nextBytes(byteArray);
// get fisrt element
System.out.println("Random byte: " + byteArray[0]);

you can use $nbsp; for a single space, if you like just using single allows you single space instead of using creating own class

    <div id="bulkOptionContainer" class="col-xs-4">
        <select class="form-control" name="" id="">
            <option value="">Select Options</option>
            <option value="">Published</option>
            <option value="">Draft</option>
            <option value="">Delete</option>
        </select>
    </div>

    <div class="col-xs-4">

        <input type="submit" name="submit" class="btn btn-success " value="Apply">
         &nbsp;
        <a class="btn btn-primary" href="add_posts.php">Add post</a>

    </div>


</form>

CLICK ON IMAGE

The answers above didn't work for me. Here's how I got around it:

1) in finder, delete the entire Pods folder and Podfile.lock file 2) close the xcode project 3) run pod install in the terminal 4) open the xcode project, run the clean build command

Worked for me after that.

First of all, the best answer for the literal question is

Hash === @some_var

But the question really should have been answered by showing how to do duck-typing here. That depends a bit on what kind of duck you need.

@some_var.respond_to?(:each_pair)

or

@some_var.respond_to?(:has_key?)

or even

@some_var.respond_to?(:to_hash)

may be right depending on the application.

As per this PPI calculation tool, Google Nexus 10 has a display density of about 300 DPI...

However, Android documentation states that:

ldpi : ~120dpi mdpi : ~160dpi hdpi : ~240dpi xhdpi : ~320dpi xxhdpi is not specified.

I think we just let Android OS scale up xhdpi resources...

You can get the count by the below query (without * or any column names).

select from table_name;

While most people have answered the question directly, I wanted to elaborate more on the concept behind it. First, I was drawn to the attention of IME when I created a default Login Activity. It generated some code for me which included the following:

<EditText
  android:id="@+id/password"
  android:layout_width="match_parent"
  android:layout_height="wrap_content"
  android:hint="@string/prompt_password"
  android:imeActionId="@+id/login"
  android:imeActionLabel="@string/action_sign_in_short"
  android:imeOptions="actionUnspecified"
  android:inputType="textPassword"
  android:maxLines="1"
  android:singleLine="true"/>

You should already be familiar with the inputType attribute. This just informs Android the type of text expected such as an email address, password or phone number. The full list of possible values can be found here.

It was, however, the attribute imeOptions="actionUnspecified" that I didn't understand its purpose. Android allows you to interact with the keyboard that pops up from bottom of screen when text is selected using the InputMethodManager. On the bottom corner of the keyboard, there is a button, typically it says "Next" or "Done", depending on the current text field. Android allows you to customize this using android:imeOptions. You can specify a "Send" button or "Next" button. The full list can be found here.

With that, you can then listen for presses on the action button by defining a TextView.OnEditorActionListener for the EditText element. As in your example:

editText.setOnEditorActionListener(new EditText.OnEditorActionListener() {
    @Override
    public boolean onEditorAction(EditText v, int actionId, KeyEvent event) {
    if (actionId == EditorInfo.IME_ACTION_DONE) {
       //do here your stuff f
       return true;
    }
    return false;
    } 
});

Now in my example I had android:imeOptions="actionUnspecified" attribute. This is useful when you want to try to login a user when they press the enter key. In your Activity, you can detect this tag and then attempt the login:

    mPasswordView = (EditText) findViewById(R.id.password);
    mPasswordView.setOnEditorActionListener(new TextView.OnEditorActionListener() {
        @Override
        public boolean onEditorAction(TextView textView, int id, KeyEvent keyEvent) {
            if (id == R.id.login || id == EditorInfo.IME_NULL) {
                attemptLogin();
                return true;
            }
            return false;
        }
    });

I've found a simple soluition for this by creating a base activity class , u must extend all your activity classes from this :

public class BaseActivity extends ActionBarActivity {

@Override
protected void onResume() {
    ApplicationStateChecker.view_resumed(this);
    super.onResume();
}

@Override
protected void onStop() {
    ApplicationStateChecker.view_stopped(this);
    super.onStop();

}

@Override
protected void onPause() {
    ApplicationStateChecker.view_paused(this);
    super.onPause();

}

}

ApplicationStateChecker class :

public class ApplicationStateChecker {

private  static final String _pause_string = "paused";
private  static final String _resume_string = "resumed";

For me, all proposed solutions won't worked. This can help, if you use cgi, fastcig or fpm as proxy you have to add a location in your vhost to avoid this problem. This allows 404 to be passthrough proxy.

With heirloom-mailx you can change sendmail program to your hook script, replace headers there and then use sendmail.

The script I use (~/bin/sendmail-hook):

#!/bin/bash

sed '1,/^$/{
s,^\(Content-Type: \).*$,\1text/html; charset=utf-8,g
s,^\(Content-Transfer-Encoding: \).*$,\18bit,g
}' | sendmail $@

This script changes the values in the mail header as follows:

• Content-Type: to text/html; charset=utf-8
• Content-Transfer-Encoding: to 8bit (not sure if this is really needed).

To send HTML email:

mail -Ssendmail='~/bin/sendmail-hook' \
    -s "Built notification" [email protected] < /var/www/report.csv

Have to add this based on @Joseph's answer. If someone want to create image object:

var image = new Image();
image.onload = function(){
   console.log(image.width); // image is loaded and we have image width 
}
image.src = 'data:image/png;base64,iVBORw0K...';
document.body.appendChild(image);

Reference Link

android:versionCode

An internal version number. This number is used only to determine whether one version is more recent than another, with higher numbers indicating more recent versions. This is not the version number shown to users; that number is set by the versionName attribute. The value must be set as an integer, such as "100". You can define it however you want, as long as each successive version has a higher number. [...]

android:versionName

The version name shown to users. This attribute can be set as a raw string or as a reference to a string resource. The string has no other purpose than to be displayed to users. The versionCode attribute holds the significant version number used internally.

Reading that it's pretty clear that versionName is just something that's shown to the user, versionCode is what matters. Just keep increasing it and everything should be good.

Other alternative:

JAXBElement<String> element = new JAXBElement<>(new QName("Your localPart"),
                                                String.class, "Your message");

Then:

System.out.println(element.getValue()); // Result: Your message

A Different Answer: Legal issues.

There's a couple of things to note before you do this. First, to get this error, in IE, inspect element, switch your tabs, and look for the errors, I believe "CSS3114" appears in the console.

What you need to understand is this is a licensing issue. I.E. (pun intended) if you are trying to load a font that causes this error, you don't have permissions on the file to use the font, and if you don't have permission, it is highly likely that you may lose a legal battle (which itself is highly unlikely) over using this font in this manner unless you are holding the license. So, you can, for the first time, thank IE for being the only browser to tell you "no", because it at least lets you know that you are doing something questionable.

That said, here is your answer:

First ensure you're using the best code in .css, see some of the other css answers for that.
IE 11 css example (works in all modern browsers may need to be tweaked for IE9):

@font-face {
font-family: "QuestionableLegalFont";
font-weight: bold;
src: url('../fonts/QuestionableLegalFont.ttf') format('truetype');
}

Then, ensure you have a working web-font (you probably already know this by seeing your font in other browsers). If you need an online font converter, check here: https://onlinefontconverter.com/

If we're going to be as sloppy as to use tolower(), do this:

char blah[] = "blah blah Blah BLAH blAH\0"; int i=0; while(blah[i]|=' ', blah[++i]) {}

But, well, it kinda explodes if you feed it some symbols/numerals, and in general it's evil. Good interview question, though.

I was having this issue intermittently. Unbeknownst to me, BackboneJS was running on the page and replacing the element I was trying to click. My code looked like this.

driver.findElement(By.id("checkoutLink")).click();

Which is of course functionally the same as this.

WebElement checkoutLink = driver.findElement(By.id("checkoutLink"));
checkoutLink.click();

What would occasionally happen was the javascript would replace the checkoutLink element in between finding and clicking it, ie.

WebElement checkoutLink = driver.findElement(By.id("checkoutLink"));
// javascript replaces checkoutLink
checkoutLink.click();

Which rightfully led to a StaleElementReferenceException when trying to click the link. I couldn't find any reliable way to tell WebDriver to wait until the javascript had finished running, so here's how I eventually solved it.

new WebDriverWait(driver, timeout)
    .ignoring(StaleElementReferenceException.class)
    .until(new Predicate<WebDriver>() {
        @Override
        public boolean apply(@Nullable WebDriver driver) {
            driver.findElement(By.id("checkoutLink")).click();
            return true;
        }
    });

This code will continually try to click the link, ignoring StaleElementReferenceExceptions until either the click succeeds or the timeout is reached. I like this solution because it saves you having to write any retry logic, and uses only the built-in constructs of WebDriver.

Not always there's a servlet before of an upload (I could use a filter for example). Or could be that the same controller ( again a filter or also a servelt ) can serve many actions, so I think that rely on that servlet configuration to use the getPart method (only for Servlet API >= 3.0), I don't know, I don't like.

In general, I prefer independent solutions, able to live alone, and in this case http://commons.apache.org/proper/commons-fileupload/ is one of that.

List<FileItem> multiparts = new ServletFileUpload(new DiskFileItemFactory()).parseRequest(request);
    for (FileItem item : multiparts) {
        if (!item.isFormField()) {
            //your operations on file
        } else {
            String name = item.getFieldName();
            String value = item.getString();
            //you operations on paramters
        }
}

I know it's for a long time ago but you (or any other new comers) can resolve this issue by

1. Add the [Domain\User] to Administrator, IISUser, SQLReportingUser groups
2. Delete Encryption Key in SSRS configuration tools
3. ReRun the Database Change in SSRS configuration tools
4. Open WebServiceUrl from SSRS configuration tools (http://localhost/reportserver)
5. creating Reports Folder manually
6. go to Properties of created folder and add these roles to security (builtin\users , builtin\Administrator, domain\user)
7. Deploy your reports and your problem resolved

Here is the Koltin style, I use this in my project and it works very well:

this.yourview.setOnTouchListener(View.OnTouchListener { _, event ->
        val x = event.x
        val y = event.y

        when(event.action) {
            MotionEvent.ACTION_DOWN -> {
                Log.d(TAG, "ACTION_DOWN \nx: $x\ny: $y")
            }
            MotionEvent.ACTION_MOVE -> {
                Log.d(TAG, "ACTION_MOVE \nx: $x\ny: $y")
            }
            MotionEvent.ACTION_UP -> {
                Log.d(TAG, "ACTION_UP \nx: $x\ny: $y")
            }
        }
        return@OnTouchListener  true
    })

This is a common problem, so here's a relatively thorough illustration.

For non-unicode strings (i.e. those without u prefix like u'\xc4pple'), one must decode from the native encoding (iso8859-1/latin1, unless modified with the enigmatic sys.setdefaultencoding function) to unicode, then encode to a character set that can display the characters you wish, in this case I'd recommend UTF-8.

First, here is a handy utility function that'll help illuminate the patterns of Python 2.7 string and unicode:

>>> def tell_me_about(s): return (type(s), s)

A plain string

>>> v = "\xC4pple" # iso-8859-1 aka latin1 encoded string

>>> tell_me_about(v)
(<type 'str'>, '\xc4pple')

>>> v
'\xc4pple'        # representation in memory

>>> print v
?pple             # map the iso-8859-1 in-memory to iso-8859-1 chars
                  # note that '\xc4' has no representation in iso-8859-1, 
                  # so is printed as "?".

Decoding a iso8859-1 string - convert plain string to unicode

>>> uv = v.decode("iso-8859-1")
>>> uv
u'\xc4pple'       # decoding iso-8859-1 becomes unicode, in memory

>>> tell_me_about(uv)
(<type 'unicode'>, u'\xc4pple')

>>> print v.decode("iso-8859-1")
Äpple             # convert unicode to the default character set
                  # (utf-8, based on sys.stdout.encoding)

>>> v.decode('iso-8859-1') == u'\xc4pple'
True              # one could have just used a unicode representation 
                  # from the start

A little more illustration — with “Ä”

>>> u"Ä" == u"\xc4"
True              # the native unicode char and escaped versions are the same

>>> "Ä" == u"\xc4"  
False             # the native unicode char is '\xc3\x84' in latin1

>>> "Ä".decode('utf8') == u"\xc4"
True              # one can decode the string to get unicode

>>> "Ä" == "\xc4"
False             # the native character and the escaped string are
                  # of course not equal ('\xc3\x84' != '\xc4').

Encoding to UTF

>>> u8 = v.decode("iso-8859-1").encode("utf-8")
>>> u8
'\xc3\x84pple'    # convert iso-8859-1 to unicode to utf-8

>>> tell_me_about(u8)
(<type 'str'>, '\xc3\x84pple')

>>> u16 = v.decode('iso-8859-1').encode('utf-16')
>>> tell_me_about(u16)
(<type 'str'>, '\xff\xfe\xc4\x00p\x00p\x00l\x00e\x00')

>>> tell_me_about(u8.decode('utf8'))
(<type 'unicode'>, u'\xc4pple')

>>> tell_me_about(u16.decode('utf16'))
(<type 'unicode'>, u'\xc4pple')

Relationship between unicode and UTF and latin1

>>> print u8
Äpple             # printing utf-8 - because of the encoding we now know
                  # how to print the characters

>>> print u8.decode('utf-8') # printing unicode
Äpple

>>> print u16     # printing 'bytes' of u16
???pple

>>> print u16.decode('utf16')
Äpple             # printing unicode

>>> v == u8
False             # v is a iso8859-1 string; u8 is a utf-8 string

>>> v.decode('iso8859-1') == u8
False             # v.decode(...) returns unicode

>>> u8.decode('utf-8') == v.decode('latin1') == u16.decode('utf-16')
True              # all decode to the same unicode memory representation
                  # (latin1 is iso-8859-1)

Unicode Exceptions

 >>> u8.encode('iso8859-1')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 0:
  ordinal not in range(128)

>>> u16.encode('iso8859-1')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
UnicodeDecodeError: 'ascii' codec can't decode byte 0xff in position 0:
  ordinal not in range(128)

>>> v.encode('iso8859-1')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc4 in position 0:
  ordinal not in range(128)

One would get around these by converting from the specific encoding (latin-1, utf8, utf16) to unicode e.g. u8.decode('utf8').encode('latin1').

So perhaps one could draw the following principles and generalizations:

• a type str is a set of bytes, which may have one of a number of encodings such as Latin-1, UTF-8, and UTF-16
• a type unicode is a set of bytes that can be converted to any number of encodings, most commonly UTF-8 and latin-1 (iso8859-1)
• the print command has its own logic for encoding, set to sys.stdout.encoding and defaulting to UTF-8
• One must decode a str to unicode before converting to another encoding.

Of course, all of this changes in Python 3.x.

Hope that is illuminating.

<select name="FakeName" id="Fake-ID" aria-required="true" required>  <?php $options=nl2br(file_get_contents("employees.txt")); $options=explode("<br />",$options);  foreach ($options as $item_array) { echo "<option value='".$item_array"'>".$item_array"</option>";  } ?> </select> 

Use:

DefaultTableModel model = new DefaultTableModel(); 
JTable table = new JTable(model); 

// Create a couple of columns 
model.addColumn("Col1"); 
model.addColumn("Col2"); 

// Append a row 
model.addRow(new Object[]{"v1", "v2"});

Solved myself. Done some small structural changes also. Route from Component1 to Component2 is done by a single <router-outlet>. Component2 to Comonent3 and Component4 is done by multiple <router-outlet name= "xxxxx"> The resulting contents are :

Component1.html

<nav>
    <a routerLink="/two" class="dash-item">Go to 2</a>
</nav>
    <router-outlet></router-outlet>

Component2.html

 <a [routerLink]="['/two', {outlets: {'nameThree': ['three']}}]">In Two...Go to 3 ...       </a>
 <a [routerLink]="['/two', {outlets: {'nameFour': ['four']}}]">   In Two...Go to 4 ...</a>

 <router-outlet name="nameThree"></router-outlet>
 <router-outlet name="nameFour"></router-outlet>

The '/two' represents the parent component and ['three']and ['four'] represents the link to the respective children of component2 . Component3.html and Component4.html are the same as in the question.

router.module.ts

const routes: Routes = [
{
    path: '',
    redirectTo: 'one',
    pathMatch: 'full'
},
{
    path: 'two',
    component: ClassTwo, children: [

        {
            path: 'three',
            component: ClassThree,
            outlet: 'nameThree'
        },
        {
            path: 'four',
            component: ClassFour,
            outlet: 'nameFour'
        }
    ]
},];

If you want the accepted answer to work in JQuery 3 change the code like this:

var scrollItems = menuItems.map(function () {
    var id = $(this).attr("href");
    try {
        var item = $(id);
      if (item.length) {
        return item;
      }
    } catch {}
  });

I also added a try-catch to prevent javascript from crashing if there is no element by that id. Feel free to improve it even more ;)

Using android 3.0.1 I noticed this weird behavior(solution), First: in background layer in the source_asset change the asset_type from image to color and than change it back to image. second: enable trim in scaling and then resize it to a small percentage and it will work perfectly. PS: If u didn't do the first step the scaling wont take affect. and if anyone have an explanation for this please provide. steps

Only this code real works!

$('#tabs').tabs();
$('#tabs').tabs('select', '#sample-tab-2');

Use like below:

  yourFunc(input: any):Observable<string> {
var requestHeader = { headers: new HttpHeaders({ 'Content-Type': 'text/plain', 'No-Auth': 'False' })};
const headers = new HttpHeaders().set('Content-Type', 'text/plain; charset=utf-8');
return this.http.post<string>(this.yourBaseApi+ '/do-api', input, { headers, responseType: 'text' as 'json'  });

}

func letterize() -> [Character] {
    return Array(self.characters)
}

If you have access to the registry but the error is still occurred nothing mentioned above wouldn't work. I noted that this problem is only applicable for local project's installation (i.e. if you use -g to global install everything is working fine).

What's resolved the problem for me: just remove an entry regarding a package you're going to install from a project's package.json file. After that next call to npm will work and install the package successfully.
