If it is giving you relay access denied when you are trying to send an email from outside your network to a domain that your server is not authoritative for then it means your receive connector does not grant you the permissions for sending/relaying. Most likely what you need to do is to authenticate to the server to be granted the permissions for relaying but that does depend upon the configuration of your receive connector. In Exchange 2007/2010/2013 you would need to enable ExchangeUsers permission group as well as an authentication mechanism such as Basic authentication.

Once you're sure your receive connector is configured make sure your email client is configured for authentication as well for the SMTP server. It depends upon your server setup but normally for Exchange you would configure the username by itself, no need for the domain to appended or prefixed to it.

To test things out with authentication via telnet you can go over my post here for directions: https://jefferyland.wordpress.com/2013/05/28/essential-exchange-troubleshooting-send-email-via-telnet/

You can do this:

add-pssnapin Microsoft.Exchange.Management.PowerShell.E2010

and most of it will work (although MS support will tell you that doing this is not supported because it bypasses RBAC).

I've seen issues with some cmdlets (specifically enable/disable UMmailbox) not working with just the snapin loaded.

In Exchange 2010, they basically don't support using Powershell outside of the the implicit remoting environment of an actual EMS shell.

For Office 365 users or Hybrid exchange, go to using Internet Explorer or Edge, go to the exchange admin center, choose hybrid, setup, chose the right button for hybrid or exchange online.

To connect:

Connect-EXOPSSession

To see the relevant mailboxes:

Get-mailbox -filter {ExchangeUserAccountControl -eq 'AccountDisabled' -and RecipientType -eq 'UserMailbox' -and RecipientTypeDetails -ne 'SharedMailbox' }

To block based on the above idea of 0KB size:

Get-mailbox -filter {ExchangeUserAccountControl -eq 'AccountDisabled' -and RecipientTypeDetails -ne 'SharedMailbox' -and RecipientType -eq 'UserMailbox' } | Set-Mailbox -MaxReceiveSize 0KB -HiddenFromAddressListsEnabled $true

Setting the UseDefaultCredentials after setting the Credentials would be resetting your Credentials property.

I had the same problem you did - didn't find much that worked. The following code, however, works like a charm.

import win32com.client

outlook = win32com.client.Dispatch("Outlook.Application").GetNamespace("MAPI")

inbox = outlook.GetDefaultFolder(6) # "6" refers to the index of a folder - in this case,
                                    # the inbox. You can change that number to reference
                                    # any other folder
messages = inbox.Items
message = messages.GetLast()
body_content = message.body
print body_content

It's a mess. MAPI or CDO via a .NET interop DLL is officially unsupported by Microsoft--it will appear to work fine, but there are problems with memory leaks due to their differing memory models. You could use CDOEX, but that only works on the Exchange server itself, not remotely; useless. You could interop with Outlook, but now you've just made a dependency on Outlook; overkill. Finally, you could use Exchange 2003's WebDAV support, but WebDAV is complicated, .NET has poor built-in support for it, and (to add insult to injury) Exchange 2007 nearly completely drops WebDAV support.

What's a guy to do? I ended up using AfterLogic's IMAP component to communicate with my Exchange 2003 server via IMAP, and this ended up working very well. (I normally seek out free or open-source libraries, but I found all of the .NET ones wanting--especially when it comes to some of the quirks of 2003's IMAP implementation--and this one was cheap enough and worked on the first try. I know there are others out there.)

If your organization is on Exchange 2007, however, you're in luck. Exchange 2007 comes with a SOAP-based Web service interface that finally provides a unified, language-independent way of interacting with the Exchange server. If you can make 2007+ a requirement, this is definitely the way to go. (Sadly for me, my company has a "but 2003 isn't broken" policy.)

If you need to bridge both Exchange 2003 and 2007, IMAP or POP3 is definitely the way to go.

If you're using jQuery 1.5, then statusCode will work.

If you're using jQuery 1.4, try this:

error: function(jqXHR, textStatus, errorThrown) {
    alert(jqXHR.status);
    alert(textStatus);
    alert(errorThrown);
}

You should see the status code from the first alert.

I hate commenting on such a screwed up situation, but the easiest way to not rejigger all of your invariants is to create a phantom vertex in your graph that acts as a proxy back to the incestuous dad.

1. Implement javax.servlet.Filter.
2. In doFilter() method, cast the incoming ServletRequest to HttpServletRequest.
3. Use HttpServletRequest#getRequestURI() to grab the path.
4. Use straightforward java.lang.String methods like substring(), split(), concat() and so on to extract the part of interest and compose the new path.
5. Use either ServletRequest#getRequestDispatcher() and then RequestDispatcher#forward() to forward the request/response to the new URL (server-side redirect, not reflected in browser address bar), or cast the incoming ServletResponse to HttpServletResponse and then HttpServletResponse#sendRedirect() to redirect the response to the new URL (client side redirect, reflected in browser address bar).
6. Register the filter in web.xml on an url-pattern of /* or /Check_License/*, depending on the context path, or if you're on Servlet 3.0 already, use the @WebFilter annotation for that instead.

Don't forget to add a check in the code if the URL needs to be changed and if not, then just call FilterChain#doFilter(), else it will call itself in an infinite loop.

Alternatively you can also just use an existing 3rd party API to do all the work for you, such as Tuckey's UrlRewriteFilter which can be configured the way as you would do with Apache's mod_rewrite.

In fact I would not use any REDIM, nor a loop for transferring data from sheet to array:

dim arOne()
arOne = range("A2:F1000")

or even

arOne = range("A2").CurrentRegion

and that's it, your array is filled much faster then with a loop, no redim.

In Firefox you can disable all autocomplete on a form by using the autocomplete="off/on" attribute. Likewise individual items autocomplete can be set using the same attribute.

<form autocomplete="off" method=".." action="..">  
<input type="text" name="textboxname" autocomplete="off">

You can test this in Chrome as it should work.

Anton,

As a best practice one should n't create user objects in the primary filegroup. When you have bandwidth, create a new file group and move the user objects and leave the system objects in primary.

The following queries will help you identify the space used in each file and the top tables that have highest number of rows and if there are any heaps. Its a good starting point to investigate this issue.

SELECT  
ds.name as filegroupname
, df.name AS 'FileName' 
, physical_name AS 'PhysicalName'
, size/128 AS 'TotalSizeinMB'
, size/128.0 - CAST(FILEPROPERTY(df.name, 'SpaceUsed') AS int)/128.0 AS 'AvailableSpaceInMB' 
, CAST(FILEPROPERTY(df.name, 'SpaceUsed') AS int)/128.0 AS 'ActualSpaceUsedInMB'
, (CAST(FILEPROPERTY(df.name, 'SpaceUsed') AS int)/128.0)/(size/128)*100. as '%SpaceUsed'
FROM sys.database_files df LEFT OUTER JOIN sys.data_spaces ds  
    ON df.data_space_id = ds.data_space_id;

EXEC xp_fixeddrives
select  t.name as TableName,  
    i.name as IndexName, 
    p.rows as Rows
from sys.filegroups fg (nolock) join sys.database_files df (nolock)
    on fg.data_space_id = df.data_space_id join sys.indexes i (nolock) 
    on df.data_space_id = i.data_space_id join sys.tables t (nolock)
    on i.object_id = t.object_id join sys.partitions p (nolock)
on t.object_id = p.object_id and i.index_id = p.index_id  
where fg.name = 'PRIMARY' and t.type = 'U'  
order by rows desc
select  t.name as TableName,  
    i.name as IndexName, 
    p.rows as Rows
from sys.filegroups fg (nolock) join sys.database_files df (nolock)
    on fg.data_space_id = df.data_space_id join sys.indexes i (nolock) 
    on df.data_space_id = i.data_space_id join sys.tables t (nolock)
    on i.object_id = t.object_id join sys.partitions p (nolock)
on t.object_id = p.object_id and i.index_id = p.index_id  
where fg.name = 'PRIMARY' and t.type = 'U' and i.index_id = 0 
order by rows desc

You can use the grep alternative sift here (disclaimer: I am the author).

It support multiline matching and limiting the search to specific file types out of the box:

sift -m --files '*.py' 'YOUR_PATTERN'

(search all *.py files for the specified multiline regex pattern)

It is available for all major operating systems. Take a look at the samples page to see how it can be used to to extract multiline values from an XML file.

For Mac OSX I had to do

tar -zcv --exclude='folder' -f theOutputTarFile.tar folderToTar

Note the -f after the --exclude=

Go to your folder path in cmd where your angular is installed and type ng --version it will show your angular version. Thanks.

My suggestion:

echo "my errz" >> /proc/self/fd/2

or

echo "my errz" >> /dev/stderr

echo "my errz" > /proc/self/fd/2 will effectively output to stderr because /proc/self is a link to the current process, and /proc/self/fd holds the process opened file descriptors, and then, 0, 1, and 2 stand for stdin, stdout and stderr respectively.

The /proc/self link doesn't work on MacOS, however, /proc/self/fd/* is available on Termux on Android, but not /dev/stderr. How to detect the OS from a Bash script? can help if you need to make your script more portable by determining which variant to use.

You have broken version of RVM. Ubuntu does something to RVM that produces lots of errors, the only safe way of fixing for now is to:

sudo apt-get --purge remove ruby-rvm
sudo rm -rf /usr/share/ruby-rvm /etc/rvmrc /etc/profile.d/rvm.sh

open new terminal and validate environment is clean from old RVM settings (should be no output):

env | grep rvm

if there was output, try to open new terminal, if it does not help then restart your computer.

install RVM:

\curl -L https://get.rvm.io | 
  bash -s stable --ruby --autolibs=enable --auto-dotfiles

If you find you need some hand-holding, take a look at Installing Ruby on Ubuntu 12.04, which gives a bit more explanation.

You are looking to see if a single value is in an array. Use in_array.

However note that case is important, as are any leading or trailing spaces. Use var_dump to find out the length of the strings too, and see if they fit.

For the latest (Juno) eclipse cdt the following worked for me, no need to declare __GXX_EXPERIMENTAL_CXX0X__ on myself. This works for the the CDT indexer and as parameter for the compiler:

"your project name" -> right click -> properties:

C/C++ General -> Preprocessor Include Paths, Macros etc. -> switch to the tab named "Providers":

• for "Configuration" select "Release" (and afterwards "debug")

• switch off all providers and just select "CDT GCC Built-in Compiler Settings"

• uncheck "Share setting entries between projects (global provider)"

• in the "Command to get compiler specs:" add "-std=c++11" without the quotes (may work with quotes too)

• hit apply and close the options

• rebuild the index

Now all the c++11 related stuff should be resolved correctly by the indexer.

win7 x64, latest official eclipse with cdt mingw-w64 gcc 4.7.2 from the mingwbuilds project on sourceforge

stdbool.h defines macros true and false, but remember they are defined to be 1 and 0.

That is why sizeof(true) is 4.

I had the same issue, can't say I know what caused it, but I just closed Android Studio, renamed the c:\users\MY USERNAME\.gradle directory to old-.gradle and then re-launched Android Studio.

Android studio then re-created the directory and automatically downloaded the gradle zip file and set it all up.

Seems to all be fine but to be honest I don't know what this directory is nor what the root cause of the problem was either, so proceed with caution and keep the old .gradle folder around for a bit until you're happy all is working fine.

<a href="@Url.Action("DeleteBlog")" class="btn btn-sm btn-danger" onclick="return confirm ('Are you sure want to delete blog?');">

This blog can help you. The trick is to use SpEL (spring expression language) to read the system properties like user.home, to read user home directory using SpEL you could use
#{ systemProperties['user.home']} expression inside your bean elements. For example to access your properties file stored in your home directory you could use the following in your PropertyPlaceholderConfigurer, it worked for me.

 <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    <property name="locations">
        <value>file:#{ systemProperties['user.home']}/ur_folder/settings.properties</value>
    </property>
</bean>

I had added, the JAVA_HOME variable in my environment variables and then it worked.

The httpd dæmon on OpenBSD uses the following stylesheet for all of its error messages, which presumably covers all the Comic Sans variations on non-Windows systems:

http://openbsd.su/src/usr.sbin/httpd/server_http.c#server_abort_http

810    style = "body { background-color: white; color: black; font-family: "
811        "'Comic Sans MS', 'Chalkboard SE', 'Comic Neue', sans-serif; }\n"
812        "hr { border: 0; border-bottom: 1px dashed; }\n";

E.g., try this:

font-family: 'Comic Sans MS', 'Chalkboard SE', 'Comic Neue', sans-serif;

Heroes of Might and Magic V used modified Silent Storm engine. I think you can find many good engines listed in wikipedia: Lua-scriptable game engines

Thats where asp.net puts dynamically compiled assemblies.

The complete way would be:

bool b1;
bool? b2 = ???;
if (b2.HasValue)
   b1 = b2.Value;

Or you can test for specific values using

bool b3 = (b2 == true); // b2 is true, not false or null

IF by changing or creating the .studio.exe.vmoptions doesn't work, then try changing the gradle.properties file and change the heap size as per your requirement.

It really worked for me on my Windows 7 with 4Gb RAM and Android Studio 2.2 install on it.

Working properly with no error and displaying 'Gradle Sync complete'

If you're using knockout, then this even cleaner. Imagine you have the following:

var dialog = $('#my-dialog').dialog({_x000D_
    width: '100%',_x000D_
    buttons: [_x000D_
        { text: 'Submit', click: $.noop, 'data-bind': 'enable: items() && items().length > 0, click: onSubmitClicked' },_x000D_
        { text: 'Enable Submit', click: $.noop, 'data-bind': 'click: onEnableSubmitClicked' }_x000D_
    ]_x000D_
});_x000D_
_x000D_
function ViewModel(dialog) {_x000D_
    var self = this;_x000D_
_x000D_
    this.items = ko.observableArray([]);_x000D_
_x000D_
    this.onSubmitClicked = function () {_x000D_
        dialog.dialog('option', 'title', 'On Submit Clicked!');_x000D_
    };_x000D_
_x000D_
    this.onEnableSubmitClicked = function () {_x000D_
        dialog.dialog('option', 'title', 'Submit Button Enabled!');_x000D_
        self.items.push('TEST ITEM');_x000D_
        dialog.text('Submit button is enabled.');_x000D_
    };_x000D_
}_x000D_
_x000D_
var vm = new ViewModel(dialog);_x000D_
ko.applyBindings(vm, dialog.parent()[0]); //Don't forget to bind to the dialog parent, or the buttons won't get bound.

The magic comes from the jQuery UI source:

$( "<button></button>", props )

You can basically call ANY jQuery instance function by passing it through the button object.

For example, if you want to use HTML:

{ html: '<span class="fa fa-user"></span>User' }

Or, if you want to add a class to the button (you can do this multiple ways):

{ addClass: 'my-custom-button-class' }

Maybe you're nuts, and you want to remove the button from the dom when it's hovered:

{ mouseover: function () { $(this).remove(); } }

I'm really surprised that no one seems to have mentioned this in the countless number of threads like this...

You Can use Follow code Textbox Keypress Event:

Private Sub txtbox1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles txtbox1.KeyPress
    Try
        If Val(txtbox1.text) < 10 Then
            If Char.IsLetterOrDigit(e.KeyChar) = False And Char.IsControl(e.KeyChar) = False Then
                e.Handled = True
            End If
        Else
            e.Handled = True
        End If
    Catch ex As Exception
        ShowException(ex.Message, MESSAGEBOX_TITLE, ex)
    End Try
End Sub

This code allow numbers only and you can enter only number between 1 to 10.

almost the same thing as David G's answer but without the anonymous function, if you don't feel like including one.

s = s.substr(0, s.indexOf(',') === -1 ? s.length : s.indexOf(','));

in this case we make use of the fact that the second argument of substr is a length, and that we know our substring is starting at 0.

the top answer is not a generic solution because of the undesirable behavior if the string doesn't contain the character you are looking for.

if you want correct behavior in a generic case, use this method or David G's method, not the top answer

regex and split methods will also work, but may be somewhat slower / overkill for this specific problem.

The problem is in this method:

  public static byte[] encrypt(String toEncrypt) throws Exception{

This is the method signature which pretty much says:

• what the method name is: encrypt
• what parameter it receives: a String named toEncrypt
• its access modifier: public static
• and if it may or not throw an exception when invoked.

In this case the method signature says that when invoked this method "could" potentially throw an exception of type "Exception".

    ....
    concatURL = padString(concatURL, ' ', 16);
    byte[] encrypted = encrypt(concatURL); <-- HERE!!!!!
    String encryptedString = bytesToHex(encrypted);
    content.removeAll();
    ......

So the compilers is saying: Either you surround that with a try/catch construct or you declare the method ( where is being used ) to throw "Exception" it self.

The real problem is the "encrypt" method definition. No method should ever return "Exception", because it is too generic and may hide some other kinds of exception better is to have an specific exception.

Try this:

public static byte[] encrypt(String toEncrypt) {
    try{
      String plaintext = toEncrypt;
      String key = "01234567890abcde";
      String iv = "fedcba9876543210";

      SecretKeySpec keyspec = new SecretKeySpec(key.getBytes(), "AES");
      IvParameterSpec ivspec = new IvParameterSpec(iv.getBytes());

      Cipher cipher = Cipher.getInstance("AES/CBC/NoPadding");
      cipher.init(Cipher.ENCRYPT_MODE,keyspec,ivspec);
      byte[] encrypted = cipher.doFinal(toEncrypt.getBytes());

      return encrypted;
    } catch ( NoSuchAlgorithmException nsae ) { 
        // What can you do if the algorithm doesn't exists??
        // this usually won't happen because you would test 
        // your code before shipping. 
        // So in this case is ok to transform to another kind 
        throw new IllegalStateException( nsae );
    } catch ( NoSuchPaddingException nspe ) { 
       // What can you do when there is no such padding ( whatever that means ) ??
       // I guess not much, in either case you won't be able to encrypt the given string
        throw new IllegalStateException( nsae );
    }
    // line 109 won't say it needs a return anymore.
  }

Basically in this particular case you should make sure the cryptography package is available in the system.

Java needs an extension for the cryptography package, so, the exceptions are declared as "checked" exceptions. For you to handle when they are not present.

In this small program you cannot do anything if the cryptography package is not available, so you check that at "development" time. If those exceptions are thrown when your program is running is because you did something wrong in "development" thus a RuntimeException subclass is more appropriate.

The last line don't need a return statement anymore, in the first version you were catching the exception and doing nothing with it, that's wrong.

try { 
    // risky code ... 
} catch( Exception e ) { 
    // a bomb has just exploited
    // you should NOT ignore it 
} 

// The code continues here, but what should it do???

If the code is to fail, it is better to Fail fast

Here are some related answers:

• Catching Exceptions in Java

• When to choose checked and unchecked exceptions

• Why don’t you have to explicitly declare that you might throw some built in exceptions in Java?

• Exception other than RuntimeException

For general information: by default to ssh-connect you may simply use

user: vagrant password: vagrant

https://www.vagrantup.com/docs/boxes/base.html#quot-vagrant-quot-user

First, try: to see what vagrant insecure_private_key is in your machine config

$ vagrant ssh-config

Example:

$ vagrant ssh-config
Host default
  HostName 127.0.0.1
  User vagrant
  Port 2222
  UserKnownHostsFile /dev/null
  StrictHostKeyChecking no
  PasswordAuthentication no
  IdentityFile C:/Users/konst/.vagrant.d/insecure_private_key
  IdentitiesOnly yes
  LogLevel FATAL

http://docs.vagrantup.com/v2/cli/ssh_config.html

Second, do: Change the contents of file insecure_private_key with the contents of your personal system private key

Or use: Add it to the Vagrantfile:

Vagrant.configure("2") do |config|
  config.ssh.private_key_path = "~/.ssh/id_rsa"
  config.ssh.forward_agent = true
end

1. config.ssh.private_key_path is your local private key
2. Your private key must be available to the local ssh-agent. You can check with ssh-add -L. If it's not listed, add it with ssh-add ~/.ssh/id_rsa
3. Don't forget to add your public key to ~/.ssh/authorized_keys on the Vagrant VM. You can do it by copy-and-pasting or using a tool like ssh-copy-id (user: root password: vagrant port: 2222) ssh-copy-id '-p 2222 [email protected]'

If still does not work try this:

1. Remove insecure_private_key file from c:\Users\USERNAME\.vagrant.d\insecure_private_key

2. Run vagrant up (vagrant will be generate a new insecure_private_key file)

In other cases, it is helpful to just set forward_agent in Vagrantfile:

Vagrant::Config.run do |config|
   config.ssh.forward_agent = true
end

Useful:

Configurating git may be with git-scm.com

After setup this program and creating personal system private key will be in yours profile path: c:\users\USERNAME\.ssh\id_rsa.pub

PS: Finally - suggest you look at Ubuntu on Windows 10

Maintain a set and remove a randomly picked-up element (with choice) until the list is empty:

s = set(range(1, 6))
import random

while len(s) > 0:
  s.remove(random.choice(list(s)))
  print(s)

Three runs give three different answers:

>>>
set([1, 3, 4, 5])
set([3, 4, 5])
set([3, 4])
set([4])
set([])
>>>
set([1, 2, 3, 5])
set([2, 3, 5])
set([2, 3])
set([2])
set([])

>>>
set([1, 2, 3, 5])
set([1, 2, 3])
set([1, 2])
set([1])
set([])

You may use background-clip: border-box;

Example:

.example {
padding: 2em;
border: 10px solid rgba(51,153,0,0.65);
background-clip: border-box;
background-color: yellow;
}

<div class="example">Example with background-clip: border-box;</div>

        cnn.Close()
        dad.Dispose()
    Catch ex As Exception

First, I try without a space, rtrim($arraynama, ","); and get an error result.

Then I add a space and get a good result:

$newarraynama = rtrim($arraynama, ", ");

You could try

document.getElementsByTagName('body')[0].appendChild(i);

Now that won't do you any good if the code is running in the <head>, and running before the <body> has even been seen by the browser. If you don't want to mess with "onload" handlers, try moving your <script> block to the very end of the document instead of the <head>.

I like the trick presented by Peter N Lewis on this thread: "If n has a limited range, then you can get the result you want simply by adding a known constant multiple of [the divisor] that is greater that the absolute value of the minimum."

So if I have a value d that is in degrees and I want to take

d % 180f

and I want to avoid the problems if d is negative, then instead I just do this:

(d + 720f) % 180f

This assumes that although d may be negative, it is known that it will never be more negative than -720.

Bah, this finally worked for me (Windows 7 + Cygwin + TortoiseMerge):

In .git/config:

cmd = TortoiseMerge.exe /base:$(cygpath -d \"$BASE\") /theirs:$(cygpath -d \"$REMOTE\") /mine:$(cygpath -d \"$LOCAL\") /merged:$(cygpath -d \"$MERGED\")

Thanks to previous posters for the tip to use cygpath!

I'm using gcc as a preprocessor (for html files.) It does just what you want. It expands "#--" directives, then outputs a readable file. (NONE of the other C/HTML preprocessors I've tried do this- they concatenate lines, choke on special characters, etc.) Asuming you have gcc installed, the command line is:

gcc -E -x c -P -C -traditional-cpp code_before.cpp > code_after.cpp

(Doesn't have to be 'cpp'.) There's an excellent description of this usage at http://www.cs.tut.fi/~jkorpela/html/cpre.html.

The "-traditional-cpp" preserves whitespace & tabs.

You can easily convert the string data type to numerical data type.

Don't forget to change collectionName & FieldName. for ex : CollectionNmae : Users & FieldName : Contactno.

Try this query..

db.collectionName.find().forEach( function (x) {
x.FieldName = parseInt(x.FieldName);
db.collectionName.save(x);
});

If you are only interested in the direct parent, and not other ancestors, you can just use parent(), and give it the selector, as in target.parent('div#hello').

Example: http://jsfiddle.net/6BX9n/

function fun(evt) {
    var target = $(evt.target);    
    if (target.parent('div#hello').length) {
        alert('Your clicked element is having div#hello as parent');
    }
}

Or if you want to check to see if there are any ancestors that match, then use .parents().

Example: http://jsfiddle.net/6BX9n/1/

function fun(evt) {
    var target = $(evt.target);    
    if (target.parents('div#hello').length) {
        alert('Your clicked element is having div#hello as parent');
    }
}

I think there's a simpler way. Create a hidden input with a random name (via javascript) and set the username to that. Repeat with the password. This way your backend script knows exactly what the appropriate field name is, while keeping autocomplete in the dark.

I'm probably wrong, but it's just an idea.

The awnser of @Alireza is totally correct, but you must notice that when using this code

var res = from element in list
          group element by element.F1
              into groups
              select groups.OrderBy(p => p.F2).First();

which is simillar to this code because you ordering the list and then do the grouping so you are getting the first row of groups

var res = (from element in list)
          .OrderBy(x => x.F2)
          .GroupBy(x => x.F1)
          .Select()

Now if you want to do something more complex like take the same grouping result but take the first element of F2 and the last element of F3 or something more custom you can do it by studing the code bellow

 var res = (from element in list)
          .GroupBy(x => x.F1)
          .Select(y => new
           {
             F1 = y.FirstOrDefault().F1;
             F2 = y.First().F2;
             F3 = y.Last().F3;
           });

So you will get something like

   F1            F2             F3 
 -----------------------------------
   Nima          1990           12
   John          2001           2
   Sara          2010           4

There is also a way to do this with some restrictions. This is the code from the article:

public string RelativePath(string absPath, string relTo)
    {
        string[] absDirs = absPath.Split('\\');
        string[] relDirs = relTo.Split('\\');
        // Get the shortest of the two paths 
        int len = absDirs.Length < relDirs.Length ? absDirs.Length : relDirs.Length;
        // Use to determine where in the loop we exited 
        int lastCommonRoot = -1; int index;
        // Find common root 
        for (index = 0; index < len; index++)
        {
            if (absDirs[index] == relDirs[index])
                lastCommonRoot = index;
            else break;
        }
        // If we didn't find a common prefix then throw 
        if (lastCommonRoot == -1)
        {
            throw new ArgumentException("Paths do not have a common base");
        }
        // Build up the relative path 
        StringBuilder relativePath = new StringBuilder();
        // Add on the .. 
        for (index = lastCommonRoot + 1; index < absDirs.Length; index++)
        {
            if (absDirs[index].Length > 0) relativePath.Append("..\\");
        }
        // Add on the folders 
        for (index = lastCommonRoot + 1; index < relDirs.Length - 1; index++)
        {
            relativePath.Append(relDirs[index] + "\\");
        }
        relativePath.Append(relDirs[relDirs.Length - 1]);
        return relativePath.ToString();
    }

When executing this piece of code:

string path1 = @"C:\Inetpub\wwwroot\Project1\Master\Dev\SubDir1"; 
string path2 = @"C:\Inetpub\wwwroot\Project1\Master\Dev\SubDir2\SubDirIWant";

System.Console.WriteLine (RelativePath(path1, path2));
System.Console.WriteLine (RelativePath(path2, path1));

it prints out:

..\SubDir2\SubDirIWant
..\..\SubDir1

Here is my solution. The code should be easy enough to follow but here is the idea:

• get all inputs, selects, and textareas
• filter out all buttons and hidden fields
• filter to only enabled, visible fields
• select the first one
• focus the selected field

The code:

function focusFirst(parent) {
    $(parent).find('input, textarea, select')
        .not('input[type=hidden],input[type=button],input[type=submit],input[type=reset],input[type=image],button')
        .filter(':enabled:visible:first')
        .focus();
}

Then simply call focusFirst with your parent element or selector.

Selector:

focusFirst('form#aspnetForm');

Element:

var el = $('form#aspnetForm');
focusFirst(el);

For %appdata% take a look to

Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData)

Another command line tool is my new Xidel. It also supports XPath 2 and XQuery, contrary to the already mentioned xpath/xmlstarlet.

The title can be read like:

xidel xhtmlfile.xhtml -e /html/head/title > titleOfXHTMLPage.txt

And it also has a cool feature to export multiple variables to bash. For example

eval $(xidel xhtmlfile.xhtml -e 'title := //title, imgcount := count(//img)' --output-format bash )

sets $title to the title and $imgcount to the number of images in the file, which should be as flexible as parsing it directly in bash.

What to do to correct this is create a file called php.ini and save it in the same location as your .htaccess file and enter the following code instead:

upload_max_filesize = "250M"
post_max_size = "250M"

Just found that .Net Framework 4.5 now supports TLSv1.2

When adding spring security every http query must be authentified by login and password.

1. Go to your project in the navigator, right click on properties.

2. Go to the Java Build Path tab on the left.

3. Go to the libraries tab on top.

4. Click add external jars.

5. Go to your ADT Bundle folder, go to sdk/extras/android/support/v7/appcompat/libs.

6. Select the file android-support-v7-appcompat.jar

7. Go to order and export and check the box next to your new jar.

8. Click ok.

You can run the pipenv command with the --rm option as in:

pipenv --rm

This will remove the virtualenv created for you under ~/.virtualenvs

See https://pipenv.kennethreitz.org/en/latest/cli/#cmdoption-pipenv-rm

Try this (ES5)

console.log($("#" +  d));

ES6

console.log($(`#${d}`));

fill="#044B9466"

This is an RGBA color in hex notation inside the SVG, defined with hex values. This is valid, but not all programs can display it properly...

You can find the browser support for this syntax here: https://caniuse.com/#feat=css-rrggbbaa

As of August 2017: RGBA fill colors will display properly on Mozilla Firefox (54), Apple Safari (10.1) and Mac OS X Finder's "Quick View". However Google Chrome did not support this syntax until version 62 (was previously supported from version 54 with the Experimental Platform Features flag enabled).

In C# you can call a method of any ancestor like this:

public class A
    internal virtual void foo()
...
public class B : A
    public new void foo()
...
public class C : B
    public new void foo() {
       (this as A).foo();
    }

Also you can do this in Delphi:

type
   A=class
      procedure foo;
      ...
   B=class(A)
     procedure foo; override;
     ...
   C=class(B)
     procedure foo; override;
     ...
A(objC).foo();

But in Java you can do such focus only by some gear. One possible way is:

class A {               
   int y=10;            

   void foo(Class X) throws Exception {  
      if(X!=A.class)
         throw new Exception("Incorrect parameter of "+this.getClass().getName()+".foo("+X.getName()+")");
      y++;
      System.out.printf("A.foo(%s): y=%d\n",X.getName(),y);
   }
   void foo() throws Exception { 
      System.out.printf("A.foo()\n");
      this.foo(this.getClass()); 
   }
}

class B extends A {     
   int y=20;            

   @Override
   void foo(Class X) throws Exception { 
      if(X==B.class) { 
         y++; 
         System.out.printf("B.foo(%s): y=%d\n",X.getName(),y);
      } else { 
         System.out.printf("B.foo(%s) calls B.super.foo(%s)\n",X.getName(),X.getName());
         super.foo(X);
      } 
   }
}

class C extends B {     
   int y=30;            

   @Override
   void foo(Class X) throws Exception { 
      if(X==C.class) { 
         y++; 
         System.out.printf("C.foo(%s): y=%d\n",X.getName(),y);
      } else { 
         System.out.printf("C.foo(%s) calls C.super.foo(%s)\n",X.getName(),X.getName());
         super.foo(X);
      } 
   }

   void DoIt() {
      try {
         System.out.printf("DoIt: foo():\n");
         foo();         
         Show();

         System.out.printf("DoIt: foo(B):\n");
         foo(B.class);  
         Show();

         System.out.printf("DoIt: foo(A):\n");
         foo(A.class);  
         Show();
      } catch(Exception e) {
         //...
      }
   }

   void Show() {
      System.out.printf("Show: A.y=%d, B.y=%d, C.y=%d\n\n", ((A)this).y, ((B)this).y, ((C)this).y);
   }
} 

objC.DoIt() result output:

DoIt: foo():
A.foo()
C.foo(C): y=31
Show: A.y=10, B.y=20, C.y=31

DoIt: foo(B):
C.foo(B) calls C.super.foo(B)
B.foo(B): y=21
Show: A.y=10, B.y=21, C.y=31

DoIt: foo(A):
C.foo(A) calls C.super.foo(A)
B.foo(A) calls B.super.foo(A)
A.foo(A): y=11
Show: A.y=11, B.y=21, C.y=31

I would suggest to use ASIHTTPRequest

ASIHTTPRequest is an easy to use wrapper around the CFNetwork API that makes some of the more tedious aspects of communicating with web servers easier. It is written in Objective-C and works in both Mac OS X and iPhone applications.

It is suitable performing basic HTTP requests and interacting with REST-based services (GET / POST / PUT / DELETE). The included ASIFormDataRequest subclass makes it easy to submit POST data and files using multipart/form-data.

Please note, that the original author discontinued with this project. See the followring post for reasons and alternatives: http://allseeing-i.com/%5Brequest_release%5D;

Personally I am a big fan of AFNetworking

The ECMAScript 6 version (aka ECMAScript 2015) of JavaScript introduced string literals.

var classType = "stringbuilder";
var q = `Does JavaScript have a built-in ${classType} class?`;

Notice that back-ticks, instead of single quotes, enclose the string.

Per Microsoft's KB, try allowing programmatic access to the Visual Basic project:

1. Click the Microsoft Office Button, and then click Excel Options.
2. Click Trust Center.
3. Click Trust Center Settings.
4. Click Macro Settings.
5. Click to select the Trust access to the VBA project object model check box.
6. Click OK to close the Excel Options dialog box.
7. You may need to close and re-open excel.

Basically:

Use IncludeErrorDetailPolicy instead if CustomErrors doesn't solve it for you (e.g. if you're ASP.NET stack is >2012):

GlobalConfiguration.Configuration.IncludeErrorDetailPolicy 
= IncludeErrorDetailPolicy.Always;

Note: Be careful returning detailed error info can reveal sensitive information to 'hackers'. See Simon's comment on this answer below.

TL;DR version

For me CustomErrors didn't really help. It was already set to Off, but I still only got a measly an error has occurred message. I guess the accepted answer is from 3 years ago which is a long time in the web word nowadays. I'm using Web API 2 and ASP.NET 5 (MVC 5) and Microsoft has moved away from an IIS-only strategy, while CustomErrors is old skool IIS ;).

Anyway, I had an issue on production that I didn't have locally. And then found I couldn't see the errors in Chrome's Network tab like I could on my dev machine. In the end I managed to solve it by installing Chrome on my production server and then browsing to the app there on the server itself (e.g. on 'localhost'). Then more detailed errors appeared with stack traces and all.

Only afterwards I found this article from Jimmy Bogard (Note: Jimmy is mr. AutoMapper!). The funny thing is that his article is also from 2012, but in it he already explains that CustomErrors doesn't help for this anymore, but that you CAN change the 'Error detail' by setting a different IncludeErrorDetailPolicy in the global WebApi configuration (e.g. WebApiConfig.cs):

GlobalConfiguration.Configuration.IncludeErrorDetailPolicy 
= IncludeErrorDetailPolicy.Always;

Luckily he also explains how to set it up that webapi (2) DOES listen to your CustomErrors settings. That's a pretty sensible approach, and this allows you to go back to 2012 :P.

Note: The default value is 'LocalOnly', which explains why I was able to solve the problem the way I described, before finding this post. But I understand that not everybody can just remote to production and startup a browser (I know I mostly couldn't until I decided to go freelance AND DevOps).

You can use a vector. Instead of worry about different screen sizes you only need to create an .svg file and import it to your project using Vector Asset Studio.

Swift 3: (but also the older versions) it happen when I have assets with duplicates. Just rename the files with this issue and all go well.

It could happen also when you have made a Assets.xcassets and you have renamed the duplicates with new names so after time you forgot it and remove it to add the folder references but this one return to the duplicate files problem..

For Apache HttpClient 4.5 or newer version:

    CloseableHttpClient httpclient = HttpClients.createDefault();
    HttpPost httpPost = new HttpPost("http://targethost/login");
    String JSON_STRING="";
    HttpEntity stringEntity = new StringEntity(JSON_STRING,ContentType.APPLICATION_JSON);
    httpPost.setEntity(stringEntity);
    CloseableHttpResponse response2 = httpclient.execute(httpPost);

Note:

1 in order to make the code compile, both httpclient package and httpcore package should be imported.

2 try-catch block has been ommitted.

Reference: appache official guide

the Commons HttpClient project is now end of life, and is no longer being developed. It has been replaced by the Apache HttpComponents project in its HttpClient and HttpCore modules

Another modification:

function update() {
  $.get("response.php", function(data) {
    $("#some_div").html(data);
    window.setTimeout(update, 10000);
  });
}

The difference with this is that it waits 10 seconds AFTER the ajax call is one. So really the time between refreshes is 10 seconds + length of ajax call. The benefit of this is if your server takes longer than 10 seconds to respond, you don't get two (and eventually, many) simultaneous AJAX calls happening.

Also, if the server fails to respond, it won't keep trying.

I've used a similar method in the past using .ajax to handle even more complex behaviour:

function update() {
  $("#notice_div").html('Loading..'); 
  $.ajax({
    type: 'GET',
    url: 'response.php',
    timeout: 2000,
    success: function(data) {
      $("#some_div").html(data);
      $("#notice_div").html(''); 
      window.setTimeout(update, 10000);
    },
    error: function (XMLHttpRequest, textStatus, errorThrown) {
      $("#notice_div").html('Timeout contacting server..');
      window.setTimeout(update, 60000);
    }
}

This shows a loading message while loading (put an animated gif in there for typical "web 2.0" style). If the server times out (in this case takes longer than 2s) or any other kind of error happens, it shows an error, and it waits for 60 seconds before contacting the server again.

This can be especially beneficial when doing fast updates with a larger number of users, where you don't want everyone to suddenly cripple a lagging server with requests that are all just timing out anyways.

For a 2-d matrix I'd do the following

var data = Array(9 * 9).fill(0);
var index = (i,j) => 9*i + j;
//any reference to an index, eg. (3,4) can be done as follows
data[index(3,4)]; 

You can replace 9 with any generic ROWS and COLUMNS constants.

i was having some issues with windowhandle and tried this one. this one works good for me.

String parentWindowHandler = driver.getWindowHandle(); 
String subWindowHandler = null;

Set<String> handles = driver.getWindowHandles();
Iterator<String> iterator = handles.iterator();
while (iterator.hasNext()){
    subWindowHandler = iterator.next();
    driver.switchTo().window(subWindowHandler);

    System.out.println(subWindowHandler);
}


driver.switchTo().window(parentWindowHandler); 

The CLASS_H is an include guard; it's used to avoid the same header file being included multiple times (via different routes) within the same CPP file (or, more accurately, the same translation unit), which would lead to multiple-definition errors.

Include guards aren't needed on CPP files because, by definition, the contents of the CPP file are only read once.

You seem to have interpreted the include guards as having the same function as import statements in other languages (such as Java); that's not the case, however. The #include itself is roughly equivalent to the import in other languages.

I recommend use pod 'UITextView+Placeholder'

pod 'UITextView+Placeholder'

on your code

#import "UITextView+Placeholder.h"

////    

UITextView *textView = [[UITextView alloc] init];
textView.placeholder = @"How are you?";
textView.placeholderColor = [UIColor lightGrayColor];

I'm running MySql Server 5.7.11 and this sentence:

ALTER TABLE table_name CHANGE date_column datetime NOT NULL DEFAULT '0000-00-00 00:00:00'

is not working. But the following:

ALTER TABLE table_name CHANGE date_column datetime NOT NULL DEFAULT '1000-01-01 00:00:00'

just works.

As a sidenote, it is mentioned in the mysql docs:

The DATE type is used for values with a date part but no time part. MySQL retrieves and displays DATE values in 'YYYY-MM-DD' format. The supported range is '1000-01-01' to '9999-12-31'.

even if they also say:

Invalid DATE, DATETIME, or TIMESTAMP values are converted to the “zero” value of the appropriate type ('0000-00-00' or '0000-00-00 00:00:00').

If you're using mod_php, you could put (either in a .htaccess in /USERS or in your httpd.conf for the USERS directory)

RemoveHandler .php

or

RemoveType .php

(depending on whether PHP is enabled using AddHandler or AddType)

PHP files run from another directory will be still able to include files in /USERS (assuming that there is no open_basedir restriction), because this does not go through Apache. If a php file is accessed using apache it will be serverd as plain text.

Edit

Lance Rushing's solution of just denying access to the files is probably better

Found a way of setting auto increment in netbeans 8.0.1 here on StackoOverflow Screenshot below:

As vartec says above, the HTTP spec does not define a limit, however many servers do by default. This means, practically speaking, the lower limit is 8K. For most servers, this limit applies to the sum of the request line and ALL header fields (so keep your cookies short).

• Apache 2.0, 2.2: 8K
• nginx: 4K - 8K
• IIS: varies by version, 8K - 16K
• Tomcat: varies by version, 8K - 48K (?!)

It's worth noting that nginx uses the system page size by default, which is 4K on most systems. You can check with this tiny program:

pagesize.c:

#include <unistd.h>
#include <stdio.h>

int main() {
    int pageSize = getpagesize();
    printf("Page size on your system = %i bytes\n", pageSize);
    return 0;
}

Compile with gcc -o pagesize pagesize.c then run ./pagesize. My ubuntu server from Linode dutifully informs me the answer is 4k.

Check if you are root and quit if you are not:

if ((EUID != 0)); then
    echo "Root or Sudo  Required for script ( $(basename $0) )"
    exit
fi

Or in this example, try to create a directory in root location then try after rights were elevated.

Check if you are root and if not elevate if possible :

# Fails to create these dirs (needs sudo)
mkdir /test-dir-$(basename $0)
rmdir /test-dir-$(basename $0)

if ((EUID != 0)); then
    echo "Granting root privileges for script ( $(basename $0) )"
    if [[ -t 1 ]]; then
        sudo "$0" "$@"
    else
        exec 1> output_file
        gksu "$0" "$@"
    fi
    exit
fi
echo "Root privileges granted..."
# Creates Dirs as it now has rights
mkdir /test-dir-$(basename $0)
rmdir /test-dir-$(basename $0)

You are using field access strategy (determined by @Id annotation). Put any JPA related annotation right above each field instead of getter property

@OneToMany(targetEntity=Student.class, mappedBy="college", fetch=FetchType.EAGER)
private List<Student> students;

See Creating a shared and static library with the gnu compiler [gcc]

gcc -c -o out.o out.c

-c means to create an intermediary object file, rather than an executable.

ar rcs libout.a out.o

This creates the static library. r means to insert with replacement, c means to create a new archive, and s means to write an index. As always, see the man page for more info.

Give the form an id, and then:

document.getElementById("yourFormId").submit();

Best practice would probably be to give your link an id too, and get rid of the event handler:

document.getElementById("yourLinkId").onclick = function() {
    document.getElementById("yourFormId").submit();
}

A solution with ggplot2 :

qplot(x,y)+geom_errorbar(aes(x=x, ymin=y-sd, ymax=y+sd), width=0.25)

You can use the shell for this purpose.

Set shl = CreateObject("WScript.Shell") 
shl.Run "cmd mkdir YourDir" & copy "

Android supports the dd command.

dd if=/path/file of=/path/file

The java application takes too long to respond(maybe due start-up/jvm being cold) thus you get the proxy error.

Proxy Error

The proxy server received an invalid response from an upstream server.
 The proxy server could not handle the request GET /lin/Campaignn.jsp.

As Albert Maclang said amending the http timeout configuration may fix the issue. I suspect the java application throws a 500+ error thus the apache gateway error too. You should look in the logs.

You should use datetime.datetime.strptime:

import datetime

dt = datetime.datetime.strptime(string_date, fmt)

fmt will need to be the appropriate format for your string. You'll find the reference on how to build your format here.

Man, I never have done that in HTML 5 but I'll try. Take a look on this fiddle.

I have used some jQuery, HTML5 native events and properties and a custom attribute on input tag(this may cause problem if you try to validade your code). I didn't tested in all browsers but I think it may work.

This is the field validation JavaScript code with jQuery:

$(document).ready(function()
{
    $('input[required], input[required="required"]').each(function(i, e)
    {
        e.oninput = function(el)
        {
            el.target.setCustomValidity("");

            if (el.target.type == "email")
            {
                if (el.target.validity.patternMismatch)
                {
                    el.target.setCustomValidity("E-mail format invalid.");

                    if (el.target.validity.typeMismatch)
                    {
                         el.target.setCustomValidity("An e-mail address must be given.");
                    }
                }
            }
        };

        e.oninvalid = function(el)
        {
            el.target.setCustomValidity(!el.target.validity.valid ? e.attributes.requiredmessage.value : "");
        };
    });
});

Nice. Here is the simple form html:

<form method="post" action="" id="validation">
    <input type="text" id="name" name="name" required="required" requiredmessage="Name is required." />
    <input type="email" id="email" name="email" required="required" requiredmessage="A valid E-mail address is required." pattern="^[a-zA-Z0-9_.-]+@[a-zA-Z0-9-]+.[a-zA-Z0-9]+$" />

    <input type="submit" value="Send it!" />
</form>

The attribute requiredmessage is the custom attribute I talked about. You can set your message for each required field there cause jQuery will get from it when it will display the error message. You don't have to set each field right on JavaScript, jQuery does it for you. That regex seems to be fine(at least it block your [email protected]! haha)

As you can see on fiddle, I make an extra validation of submit form event(this goes on document.ready too):

$("#validation").on("submit", function(e)
{
    for (var i = 0; i < e.target.length; i++)
    {
        if (!e.target[i].validity.valid)
        {
            window.alert(e.target.attributes.requiredmessage.value);
            e.target.focus();
            return false;
        }
    }
});

I hope this works or helps you in anyway.

This is likely because you haven't set your compileSdkVersion to 21 in your build.gradle file. You also probably want to change your targetSdkVersion to 21.

android {
    //...
    compileSdkVersion 21

    defaultConfig {
        targetSdkVersion 21
    }
    //...
}

This requires you to have downloaded the latest SDK updates to begin with.

Once you've downloaded all the updates (don't forget to also update the Android Support Library/Repository, too!) and updated your compileSdkVersion, re-sync your Gradle project.

Edit: For Eclipse or general IntelliJ users

See reVerse's answer. He has a very thorough walk through!

You are overwriting the start date object with the value of a DOM Element with an id of Startdate.

This should work:

var start = new Date(document.getElementById('Stardate').value);

var y = start.getFullYear();

There is now a an approach to do this, using Doctrine's Criteria.

A full example can be seen in How to use a findBy method with comparative criteria, but a brief answer follows.

use \Doctrine\Common\Collections\Criteria;

// Add a not equals parameter to your criteria
$criteria = new Criteria();
$criteria->where(Criteria::expr()->neq('prize', 200));

// Find all from the repository matching your criteria
$result = $entityRepository->matching($criteria);

Have a look at numpy.split:

>>> a = numpy.array([1,2,3,4])
>>> numpy.split(a, 2)
[array([1, 2]), array([3, 4])]

The accepted answer does not work. And the highest voted answer does not answer the actual question. With a fixed pixel height header, and a filler in the remaining display of the browser, and scroll for owerflow. Here is a solution that actually works, using absolute positioning. I also assume that the height of the header is known, by the sound of "fixed header" in the question. I use 150px as an example here:

HTML:

<html>
    <body>
        <div id="Header">
        </div>
        <div id="Content">      
        </div>
    </body>
</html>

CSS:(adding background-color for visual effect only)

#Header
{
    height: 150px;
    width: 100%;
    background-color: #ddd;
}
#Content
{
   position: absolute;
   width: 100%;
   top: 150px;
   bottom: 0;
   background-color: #aaa;
   overflow-y: scroll;
}

For a more detailed look how this works, with actual content inside the #Content, have a look at this jsfiddle, using bootstrap rows and columns.

Using anytime package:

library(anytime)

anydate("2009-01")
# [1] "2009-01-01"

Note: this is JQuery. See Sébastien answer for Javascript

$(function() {
    var temp="a"; 
    $("#MySelect").val(temp);
});

<select name="MySelect" id="MySelect">
    <option value="a">a</option>
    <option value="b">b</option>
    <option value="c">c</option>
</select>

if you are like me who has tried all the above solutions and still your problem is not solved, I have a got a great solution for you that works like a charm. First I want clarify few things about some of solutions mentioned above.

1. In my case IQkeyboardmanager was working only when there is no auto layout applied on the elements, if it is applied then IQkeyboard manager will not work the way we think.
2. Same thing with upward movement of self.view.
3. i have wriiten a objective c header with a swift support for pushing UITexfield upward when user clicks on it, solving the problem of keyboard covering the UITextfield : https://github.com/coolvasanth/smart_keyboard.
4. One who has An intermediate or higher level in iOS app development can easily understand the repository and implement it. All the best

Right click project solution

Properties -> Configuration Properties -> C/C++ -> Precompiled Headers

1. Click on "Precompiled Headers" change to "Not Using Precompiled Headers".

2. Erase the "pch.h"/"stdafx.h" field in "Precompiled Header File" for the EOF error at the end of the build for the project.

3. Then you can feel free to delete the pch./stdafx. files in your project

I ran the 'ng serve' command in the command prompt. It compiled the project successfully. Then whatever changes are saved in VS Code, are automatically refreshed in the browser.

PS: I have installed angular globally.

You are giving multiple Content-Type headers. application/vnd.ms-excel is enough.

And there are couple of syntax error too. To statement termination with ; on the echo statement and wrong filename extension.

header("Content-Type:   application/vnd.ms-excel; charset=utf-8");
header("Content-Disposition: attachment; filename=abc.xls");  //File name extension was wrong
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: private",false);
echo "Some Text"; //no ending ; here

Think about statically typed language, things on prototype are static and things on this are instance related.

First off, are you setting your desired JRE or your desired JDK?

Even if your Eclipse is set up properly, there might be a wacky project-specific setting somewhere. You can open up a context menu on a given Java project in the Project Explorer and select Properties > Java Compiler to check on that.

If none of that helps, leave a comment and I'll take another look.

Looks like whatever is in your Animation Drawable definition is too much memory to decode and sequence. The idea is that it loads up all the items and make them in an array and swaps them in and out of the scene according to the timing specified for each frame.

If this all can't fit into memory, it's probably better to either do this on your own with some sort of handler or better yet just encode a movie with the specified frames at the corresponding images and play the animation through a video codec.

If by the type of a variable you mean the runtime class of the object that the variable points to, then you can get this through the class reference that all objects have.

val name = "sam";
name: java.lang.String = sam
name.getClass
res0: java.lang.Class[_] = class java.lang.String

If you however mean the type that the variable was declared as, then you cannot get that. Eg, if you say

val name: Object = "sam"

then you will still get a String back from the above code.

You could try:

agg <- aggregate(list(x$val1, x$val2, x$val3, x$val4), by = list(x$id1, x$id2), mean)

The connector section has the parameter

maxPostSize

The maximum size in bytes of the POST which will be handled by the container FORM URL parameter parsing. The limit can be disabled by setting this attribute to a value less than or equal to 0. If not specified, this attribute is set to 2097152 (2 megabytes).

Another Limit is:

maxHttpHeaderSize The maximum size of the request and response HTTP header, specified in bytes. If not specified, this attribute is set to 4096 (4 KB).

You find them in

$TOMCAT_HOME/conf/server.xml

Building on @bitsand, this is a new method I just added to my NSString+Extras category:

- (CGRect) boundingRectWithFont:(UIFont *) font constrainedToSize:(CGSize) constraintSize lineBreakMode:(NSLineBreakMode) lineBreakMode;
{
    // set paragraph style
    NSMutableParagraphStyle *style = [[NSParagraphStyle defaultParagraphStyle] mutableCopy];
    [style setLineBreakMode:lineBreakMode];

    // make dictionary of attributes with paragraph style
    NSDictionary *sizeAttributes = @{NSFontAttributeName:font, NSParagraphStyleAttributeName: style};

    CGRect frame = [self boundingRectWithSize:constraintSize options:NSStringDrawingUsesLineFragmentOrigin attributes:sizeAttributes context:nil];

    /*
    // OLD
    CGSize stringSize = [self sizeWithFont:font
                              constrainedToSize:constraintSize
                                  lineBreakMode:lineBreakMode];
    // OLD
    */

    return frame;
}

I just use the size of the resulting frame.

This error can be caused when you are requesting a value from something and you put parenthesis at the end, as if it is a function call, yet the value is correctly retrieved without ending parenthesis. For example, if what you are accessing is a Property 'get' in Typescript.

private IMadeAMistakeHere(): void {
    let mynumber = this.SuperCoolNumber();
}

private IDidItCorrectly(): void {
    let mynumber = this.SuperCoolNumber;
}

private get SuperCoolNumber(): number {
    let response = 42;
    return response;
};

You need to add an id to your select. Then:

When you use --user option with pip, the package gets installed in user's folder instead of global folder and you won't need to run pip command with admin privileges.

The location of user's packages folder can be found using:

python -m site --user-site

This will print something like:

C:\Users\%USERNAME%\AppData\Roaming\Python\Python35\site-packages

When you don't use --user option with pip, the package gets installed in global folder given by:

python -c "import site; print(site.getsitepackages())"

This will print something like:

['C:\\Program Files\\Anaconda3', 'C:\\Program Files\\Anaconda3\\lib\\site-packages'

Note: Above printed values are for On Windows 10 with Anaconda 4.x installed with defaults.

EDIT:

After your comments this actually makes perfect sense why you don't get a histogram of each different value. There are 1.4 million rows, and ten discrete buckets. So apparently each bucket is exactly 10% (to within what you can see in the plot).

A quick rerun of your data:

In [25]: df.hist(column='Trip_distance')

Prints out absolutely fine.

The df.hist function comes with an optional keyword argument bins=10 which buckets the data into discrete bins. With only 10 discrete bins and a more or less homogeneous distribution of hundreds of thousands of rows, you might not be able to see the difference in the ten different bins in your low resolution plot:

In [34]: df.hist(column='Trip_distance', bins=50)

Also, to note - the Active Record Class also has a $this->db->where_in() method.

Most likely the TinyMce editor is adding its own formatting to the post. You'll need to see how you can escape TinyMce's editing abilities. The code works fine for me. Is it a wordpress blog?

Essentially, a List<> in .NET is a wrapper over an array. A LinkedList<> is a linked list. So the question comes down to, what is the difference between an array and a linked list, and when should an array be used instead of a linked list. Probably the two most important factors in your decision of which to use would come down to:

• Linked lists have much better insertion/removal performance, so long as the insertions/removals are not on the last element in the collection. This is because an array must shift all remaining elements that come after the insertion/removal point. If the insertion/removal is at the tail end of the list however, this shift is not needed (although the array may need to be resized, if its capacity is exceeded).
• Arrays have much better accessing capabilities. Arrays can be indexed into directly (in constant time). Linked lists must be traversed (linear time).

WebSockets is definitely the future.

Long polling is a dirty workaround to prevent creating connections for each request like AJAX does -- but long polling was created when WebSockets didn't exist. Now due to WebSockets, long polling is going away.

WebRTC allows for peer-to-peer communication.

I recommend learning WebSockets.

Comparison:

of different communication techniques on the web

• AJAX - request → response. Creates a connection to the server, sends request headers with optional data, gets a response from the server, and closes the connection. Supported in all major browsers.

• Long poll - request → wait → response. Creates a connection to the server like AJAX does, but maintains a keep-alive connection open for some time (not long though). During connection, the open client can receive data from the server. The client has to reconnect periodically after the connection is closed, due to timeouts or data eof. On server side it is still treated like an HTTP request, same as AJAX, except the answer on request will happen now or some time in the future, defined by the application logic. support chart (full) | wikipedia

• WebSockets - client ↔ server. Create a TCP connection to the server, and keep it open as long as needed. The server or client can easily close the connection. The client goes through an HTTP compatible handshake process. If it succeeds, then the server and client can exchange data in both directions at any time. It is efficient if the application requires frequent data exchange in both ways. WebSockets do have data framing that includes masking for each message sent from client to server, so data is simply encrypted. support chart (very good) | wikipedia

• WebRTC - peer ↔ peer. Transport to establish communication between clients and is transport-agnostic, so it can use UDP, TCP or even more abstract layers. This is generally used for high volume data transfer, such as video/audio streaming, where reliability is secondary and a few frames or reduction in quality progression can be sacrificed in favour of response time and, at least, some data transfer. Both sides (peers) can push data to each other independently. While it can be used totally independent from any centralised servers, it still requires some way of exchanging endPoints data, where in most cases developers still use centralised servers to "link" peers. This is required only to exchange essential data for establishing a connection, after which a centralised server is not required. support chart (medium) | wikipedia

• Server-Sent Events - client ← server. Client establishes persistent and long-term connection to server. Only the server can send data to a client. If the client wants to send data to the server, it would require the use of another technology/protocol to do so. This protocol is HTTP compatible and simple to implement in most server-side platforms. This is a preferable protocol to be used instead of Long Polling. support chart (good, except IE) | wikipedia

Advantages:

The main advantage of WebSockets server-side, is that it is not an HTTP request (after handshake), but a proper message based communication protocol. This enables you to achieve huge performance and architecture advantages. For example, in node.js, you can share the same memory for different socket connections, so they can each access shared variables. Therefore, you don't need to use a database as an exchange point in the middle (like with AJAX or Long Polling with a language like PHP). You can store data in RAM, or even republish between sockets straight away.

Security considerations

People are often concerned about the security of WebSockets. The reality is that it makes little difference or even puts WebSockets as better option. First of all, with AJAX, there is a higher chance of MITM, as each request is a new TCP connection that is traversing through internet infrastructure. With WebSockets, once it's connected it is far more challenging to intercept in between, with additionally enforced frame masking when data is streamed from client to server as well as additional compression, which requires more effort to probe data. All modern protocols support both: HTTP and HTTPS (encrypted).

P.S.

Remember that WebSockets generally have a very different approach of logic for networking, more like real-time games had all this time, and not like http.

In my opinion the best way to scroll to a given rectangle is via View.requestRectangleOnScreen(Rect, Boolean). You should call it on a View you want to scroll to and pass a local rectangle you want to be visible on the screen. The second parameter should be false for smooth scrolling and true for immediate scrolling.

final Rect rect = new Rect(0, 0, view.getWidth(), view.getHeight());
view.requestRectangleOnScreen(rect, false);

You can write this in a more compact way:

var now = new Date();
now.setTime(now.getTime() + 1 * 3600 * 1000);
document.cookie = "name=value; expires=" + now.toUTCString() + "; path=/";

And for someone like me, who wasted an hour trying to figure out why the cookie with expiration is not set up (but without expiration can be set up) in Chrome, here is in answer:

For some strange reason Chrome team decided to ignore cookies from local pages. So if you do this on localhost, you will not be able to see your cookie in Chrome. So either upload it on the server or use another browser.

the accepted answer is correct.. for mobile you can also use this (ng-touched rather ng-dirty)

input.ng-invalid.ng-touched{
  border-bottom: 1px solid #e74c3c !important; 
}

Usage depends on whether the component's parent has a layout manager or not.

• setSize() -- use when a parent layout manager does not exist;
• setPreferredSize() (also its related setMinimumSize and setMaximumSize) -- use when a parent layout manager exists.

The setSize() method probably won't do anything if the component's parent is using a layout manager; the places this will typically have an effect would be on top-level components (JFrames and JWindows) and things that are inside of scrolled panes. You also must call setSize() if you've got components inside a parent without a layout manager.

Generally, setPreferredSize() will lay out the components as expected if a layout manager is present; most layout managers work by getting the preferred (as well as minimum and maximum) sizes of their components, then using setSize() and setLocation() to position those components according to the layout's rules.

For example, a BorderLayout tries to make the bounds of its "north" region equal to the preferred size of its north component---they may end up larger or smaller than that, depending on the size of the JFrame, the size of the other components in the layout, and so on.

Here is a solution using win32 api and std string in case you need your application to run on a OS with no CLR. I found it here on github.

#include "stdafx.h"
#include <windows.h>
#include <memory>
#include <string>

//returns the serial number of the first physical drive in a std::string or an empty std::string in case of failure
//based on http://codexpert.ro/blog/2013/10/26/get-physical-drive-serial-number-part-1/

    //get a handle to the first physical drive
    HANDLE h = CreateFileW(L"\\\\.\\PhysicalDrive0", 0, FILE_SHARE_READ | FILE_SHARE_WRITE, NULL, OPEN_EXISTING, 0, NULL);
    if (h == INVALID_HANDLE_VALUE) return{};
    //an std::unique_ptr is used to perform cleanup automatically when returning (i.e. to avoid code duplication)
    std::unique_ptr<std::remove_pointer<HANDLE>::type, void(*)(HANDLE)> hDevice{ h, [](HANDLE handle){CloseHandle(handle); } };
    //initialize a STORAGE_PROPERTY_QUERY data structure (to be used as input to DeviceIoControl)
    STORAGE_PROPERTY_QUERY storagePropertyQuery{};
    storagePropertyQuery.PropertyId = StorageDeviceProperty;

        &storageDescriptorHeader, sizeof(STORAGE_DESCRIPTOR_HEADER), &dwBytesReturned, NULL))
        return{};
    //allocate a suitable buffer
    const DWORD dwOutBufferSize = storageDescriptorHeader.Size;
    std::unique_ptr<BYTE[]> pOutBuffer{ new BYTE[dwOutBufferSize]{} };
    //call DeviceIoControl with the allocated buffer
    if (!DeviceIoControl(hDevice.get(), IOCTL_STORAGE_QUERY_PROPERTY, &storagePropertyQuery, sizeof(STORAGE_PROPERTY_QUERY),

    //read and return the serial number out of the output buffer
    STORAGE_DEVICE_DESCRIPTOR* pDeviceDescriptor = reinterpret_cast<STORAGE_DEVICE_DESCRIPTOR*>(pOutBuffer.get());
    const DWORD dwSerialNumberOffset = pDeviceDescriptor->SerialNumberOffset;
    if (dwSerialNumberOffset == 0) return{};
    const char* serialNumber = reinterpret_cast<const char*>(pOutBuffer.get() + dwSerialNumberOffset);
    return serialNumber;
}

#include <iostream>
int main() {
    std::string serialNumber = getFirstHddSerialNumber();
    if (serialNumber.empty())
        std::cout << "failed to retrieve serial number\n";
    else
        std::cout << "serial number: " << serialNumber << "\n";
    return 0;
}

I tried everything for hours but the following finally fixed it (I'm on OS X 10.9.4):

1. Install Xcode command line tools (Apple Developer site)
2. brew uninstall postgresql
3. brew install postgresql
4. ARCHFLAGS="-arch x86_64" gem install pg

To view the months of the current year, and only the months, use this format - it only takes the months of that year. It can also be restricted so that a certain number of months is displayed.

<input class="form-control" id="txtDateMMyyyy"  autocomplete="off" required readonly/>

<script>
('#txtDateMMyyyy').datetimepicker({
    format: "mm/yyyy",
    startView: "year",
    minView: "year"
}).datetimepicker("setDate", new Date());
</script>

I just learned (thanks to martineau's comment) that, in order to import classes from files within the same directory, you would now write in Python 3:

from .user import User
from .dir import Dir

SO @NotNull just is a tag...If you want to validate it, then you must use something like hibernate validator jsr 303

ValidatorFactory validatorFactory = Validation.buildDefaultValidatorFactory();
Validator validator = validatorFactory.getValidator();
 Set<ConstraintViolation<List<Searching>> violations = validator.validate(searchingList);

In such scenario last used key is usually known so it can be used for accessing last value (inserted with the one):

class PostIndexData {
    String _office_name;
    Boolean _isGov;
    public PostIndexData(String name, Boolean gov) {
        _office_name = name;
        _isGov = gov;
    }
}
//-----------------------
class KgpData {
    String _postIndex;
    PostIndexData _postIndexData;
    public KgpData(String postIndex, PostIndexData postIndexData) {
        _postIndex = postIndex;
        _postIndexData = postIndexData;;
    }
}

public class Office2ASMPro {
    private HashMap<String,PostIndexData> _postIndexMap = new HashMap<>();
    private HashMap<String,KgpData> _kgpMap = new HashMap<>();
...
private void addOffice(String kgp, String postIndex, String officeName, Boolean gov) {
            if (_postIndexMap.get(postIndex) == null) {
                _postIndexMap.put(postIndex, new PostIndexData(officeName, gov));
            }
            _kgpMap.put( kgp, new KgpData(postIndex, _postIndexMap.get(postIndex)) );
        }

If you have problem with libclntsh.so, need create symlink for libclntsh.so from /usr/lib/oracle/11.2/client64/lib to /usr/lib

If you prefer named parameters, it's possible (with a few tricks) to actually pass named parameters to functions (also makes it possible to pass arrays and references).

The method I developed allows you to define named parameters passed to a function like this:

function example { args : string firstName , string lastName , integer age } {
  echo "My name is ${firstName} ${lastName} and I am ${age} years old."
}

You can also annotate arguments as @required or @readonly, create ...rest arguments, create arrays from sequential arguments (using e.g. string[4]) and optionally list the arguments in multiple lines:

function example {
  args
    : @required string firstName
    : string lastName
    : integer age
    : string[] ...favoriteHobbies

  echo "My name is ${firstName} ${lastName} and I am ${age} years old."
  echo "My favorite hobbies include: ${favoriteHobbies[*]}"
}

In other words, not only you can call your parameters by their names (which makes up for a more readable core), you can actually pass arrays (and references to variables - this feature works only in Bash 4.3 though)! Plus, the mapped variables are all in the local scope, just as $1 (and others).

The code that makes this work is pretty light and works both in Bash 3 and Bash 4 (these are the only versions I've tested it with). If you're interested in more tricks like this that make developing with bash much nicer and easier, you can take a look at my Bash Infinity Framework, the code below is available as one of its functionalities.

shopt -s expand_aliases

function assignTrap {
  local evalString
  local -i paramIndex=${__paramIndex-0}
  local initialCommand="${1-}"

  if [[ "$initialCommand" != ":" ]]
  then

Optionals and default parameters are two different things.

An Optional is a variable that can be nil, that's it.

Default parameters use a default value when you omit that parameter, this default value is specified like this: func test(param: Int = 0)

If you specify a parameter that is an optional, you have to provide it, even if the value you want to pass is nil. If your function looks like this func test(param: Int?), you can't call it like this test(). Even though the parameter is optional, it doesn't have a default value.

You can also combine the two and have a parameter that takes an optional where nil is the default value, like this: func test(param: Int? = nil).

I have encountered this problem too, when using some 3rd party data layer in one of my .NET applications. The problem was that the layer did not close the connections properly.

We threw out the layer and created one ourselves, which always closes and disposes the connections. Since then we don't get the error anymore.

If you want just simple shortcuts (like 1 letter, for example just g) you could easily do it without a extra plugin:

$(document).keypress(function(e) {
  if(e.charCode == 103) {
    // Your Code
  }
});

As addition to other answers, one can write something else if variable is None like this:

{{ variable or '' }}

You can use the two dots at the end of expression, too. See this example:

//*[title="50"]/..

You can catch it like any other exception:

try {
  foo();
}
catch (const std::bad_alloc&) {
  return -1;
}

Quite what you can usefully do from this point is up to you, but it's definitely feasible technically.

In general you cannot, and should not try, to respond to this error. bad_alloc indicates that a resource cannot be allocated because not enough memory is available. In most scenarios your program cannot hope to cope with that, and terminating soon is the only meaningful behaviour.

Worse, modern operating systems often over-allocate: on such systems, malloc and new can return a valid pointer even if there is not enough free memory left – std::bad_alloc will never be thrown, or is at least not a reliable sign of memory exhaustion. Instead, attempts to access the allocated memory will then result in a segmentation fault, which is not catchable (you can handle the segmentation fault signal, but you cannot resume the program afterwards).

The only thing you could do when catching std::bad_alloc is to perhaps log the error, and try to ensure a safe program termination by freeing outstanding resources (but this is done automatically in the normal course of stack unwinding after the error gets thrown if the program uses RAII appropriately).

In certain cases, the program may attempt to free some memory and try again, or use secondary memory (= disk) instead of RAM but these opportunities only exist in very specific scenarios with strict conditions:

1. The application must ensure that it runs on a system that does not overcommit memory, i.e. it signals failure upon allocation rather than later.
2. The application must be able to free memory immediately, without any further accidental allocations in the meantime.

It’s exceedingly rare that applications have control over point 1 — userspace applications never do, it’s a system-wide setting that requires root permissions to change.¹

OK, so let’s assume you’ve fixed point 1. What you can now do is for instance use a LRU cache for some of your data (probably some particularly large business objects that can be regenerated or reloaded on demand). Next, you need to put the actual logic that may fail into a function that supports retry — in other words, if it gets aborted, you can just relaunch it:

lru_cache<widget> widget_cache;

double perform_operation(int widget_id) {
    std::optional<widget> maybe_widget = widget_cache.find_by_id(widget_id);
    if (not maybe_widget) {
        maybe_widget = widget_cache.store(widget_id, load_widget_from_disk(widget_id));
    }
    return maybe_widget->frobnicate();
}

…

for (int num_attempts = 0; num_attempts < MAX_NUM_ATTEMPTS; ++num_attempts) {
    try {
        return perform_operation(widget_id);
    } catch (std::bad_alloc const&) {
        if (widget_cache.empty()) throw; // memory error elsewhere.
        widget_cache.remove_oldest();
    }
}

// Handle too many failed attempts here.

But even here, using std::set_new_handler instead of handling std::bad_alloc provides the same benefit and would be much simpler.

¹ If you’re creating an application that does control point 1, and you’re reading this answer, please shoot me an email, I’m genuinely curious about your circumstances.

What is the C++ Standard specified behavior of new in c++?

The usual notion is that if new operator cannot allocate dynamic memory of the requested size, then it should throw an exception of type std::bad_alloc.
However, something more happens even before a bad_alloc exception is thrown:

C++03 Section 3.7.4.1.3: says

An allocation function that fails to allocate storage can invoke the currently installed new_handler(18.4.2.2), if any. [Note: A program-supplied allocation function can obtain the address of the currently installed new_handler using the set_new_handler function (18.4.2.3).] If an allocation function declared with an empty exception-specification (15.4), throw(), fails to allocate storage, it shall return a null pointer. Any other allocation function that fails to allocate storage shall only indicate failure by throw-ing an exception of class std::bad_alloc (18.4.2.1) or a class derived from std::bad_alloc.

Consider the following code sample:

#include <iostream>
#include <cstdlib>

// function to call if operator new can't allocate enough memory or error arises
void outOfMemHandler()
{
    std::cerr << "Unable to satisfy request for memory\n";

    std::abort();
}

int main()
{
    //set the new_handler
    std::set_new_handler(outOfMemHandler);

    //Request huge memory size, that will cause ::operator new to fail
    int *pBigDataArray = new int[100000000L];

    return 0;
}

In the above example, operator new (most likely) will be unable to allocate space for 100,000,000 integers, and the function outOfMemHandler() will be called, and the program will abort after issuing an error message.

As seen here the default behavior of new operator when unable to fulfill a memory request, is to call the new-handler function repeatedly until it can find enough memory or there is no more new handlers. In the above example, unless we call std::abort(), outOfMemHandler() would be called repeatedly. Therefore, the handler should either ensure that the next allocation succeeds, or register another handler, or register no handler, or not return (i.e. terminate the program). If there is no new handler and the allocation fails, the operator will throw an exception.

What is the new_handler and set_new_handler?

new_handler is a typedef for a pointer to a function that takes and returns nothing, and set_new_handler is a function that takes and returns a new_handler.

Something like:

typedef void (*new_handler)();
new_handler set_new_handler(new_handler p) throw();

set_new_handler's parameter is a pointer to the function operator new should call if it can't allocate the requested memory. Its return value is a pointer to the previously registered handler function, or null if there was no previous handler.

How to handle out of memory conditions in C++?

Given the behavior of newa well designed user program should handle out of memory conditions by providing a proper new_handlerwhich does one of the following:

Make more memory available: This may allow the next memory allocation attempt inside operator new's loop to succeed. One way to implement this is to allocate a large block of memory at program start-up, then release it for use in the program the first time the new-handler is invoked.

Install a different new-handler: If the current new-handler can't make any more memory available, and of there is another new-handler that can, then the current new-handler can install the other new-handler in its place (by calling set_new_handler). The next time operator new calls the new-handler function, it will get the one most recently installed.

(A variation on this theme is for a new-handler to modify its own behavior, so the next time it's invoked, it does something different. One way to achieve this is to have the new-handler modify static, namespace-specific, or global data that affects the new-handler's behavior.)

Uninstall the new-handler: This is done by passing a null pointer to set_new_handler. With no new-handler installed, operator new will throw an exception ((convertible to) std::bad_alloc) when memory allocation is unsuccessful.

Throw an exception convertible to std::bad_alloc. Such exceptions are not be caught by operator new, but will propagate to the site originating the request for memory.

Not return: By calling abort or exit.

Very easy, just wrap the table in a div that has overflow-y:scroll; and overflow-x:scroll properties, and make the div have a width and length smaller than the table. IT WILL WORK!!!

What ports is RabbitMQ using?

Default: 5672, the manual has the answer. It's defined in the RABBITMQ_NODE_PORT variable.

The number might be differently if changed by someone in the rabbitmq configuration file:

vi /etc/rabbitmq/rabbitmq-env.conf

I know its using a loop, but it's the simplest way to do it! And using a function it still ends up on a single line.

HTML

<span id="radiobutt">
  <input type="radio" name="rad1" value="1" />
  <input type="radio" name="rad1" value="2" />
  <input type="radio" name="rad1" value="3" />
</span>
<div>
  <input type="text" id="textbox1" />
  <input type="checkbox" id="checkbox1" />
</div>

Javascript

  $("#radiobutt input[type=radio]").each(function(i){
    $(this).click(function () {
        if(i==2) { //3rd radiobutton
            $("#textbox1").attr("disabled", "disabled"); 
            $("#checkbox1").attr("disabled", "disabled"); 
        }
        else {
            $("#textbox1").removeAttr("disabled"); 
            $("#checkbox1").removeAttr("disabled"); 
        }
      });

  });

For localhost / wampserver 3 we can set sql-mode = user_mode to remove this error:

click on wamp icon -> MySql -> MySql Setting -> sql-mode -> user_mode

then restart wamp or apache

You can actually do what Chris Chalmers does in his answer, but you must make sure that HAML doesn't parse the JavaScript. This approach is actually useful when you need to use a different type than text/javascript, which is was I needed to do for MathJax.

You can use the plain filter to keep HAML from parsing the script and throwing an illegal nesting error:

%script{type: "text/x-mathjax-config"}
  :plain
    MathJax.Hub.Config({
      tex2jax: {
        inlineMath: [["$","$"],["\\(","\\)"]]
      }
    });

After adding dependencies open "Gradle" ('View'->Tool Windows->Gradle) tab and hit "refresh"

example of adding (compile 'io.reactivex:rxjava:1.1.0'):

If Idea still can not resolve dependency, hence it is possibly the dependency is not in mavenCentral() repository and you need add repository where this dependency located into repositories{}

Simple solution: The sequence is really matter while including the auto complete libraries:

This error happens when you are trying to show popUpWindow too early ,to fix it, give Id to main layout as main_layout and use below code

Java:

 findViewById(R.id.main_layout).post(new Runnable() {
   public void run() {
       popupWindow.showAtLocation(findViewById(R.id.main_layout), Gravity.CENTER, 0, 0);
   }
});

Kotlin:

 main_layout.post {
      popupWindow?.showAtLocation(main_layout, Gravity.CENTER, 0, 0)
    }

Node's answer is really great, but it left open the question how can get stdout and stderr redirected. I found a solution on Unix & Linux, but it is also not complete. I would like to merge these two solutions. Here it is:

For my test I made a small bash script called loop.sh, which prints the pid of itself with a minute sleep in an infinite loop.

$./loop.sh

Now get the PID of this process somehow. Usually ps -C loop.sh is good enough, but it is printed in my case.

Now we can switch to another terminal (or press ^Z and in the same terminal). Now gdb should be attached to this process.

$ gdb -p <PID>

This stops the script (if running). Its state can be checked by ps -f <PID>, where the STAT field is 'T+' (or in case of ^Z 'T'), which means (man ps(1))

    T Stopped, either by a job control signal or because it is being traced
    + is in the foreground process group

(gdb) call close(1)
$1 = 0

Close(1) returns zero on success.

(gdb) call open("loop.out", 01102, 0600)
$6 = 1

Open(1) returns the new file descriptor if successful.

This open is equal with open(path, O_TRUNC|O_CREAT|O_RDWR, S_IRUSR|S_IWUSR). Instead of O_RDWR O_WRONLY could be applied, but /usr/sbin/lsof says 'u' for all std* file handlers (FD column), which is O_RDWR.

I checked the values in /usr/include/bits/fcntl.h header file.

The output file could be opened with O_APPEND, as nohup would do, but this is not suggested by man open(2), because of possible NFS problems.

If we get -1 as a return value, then call perror("") prints the error message. If we need the errno, use p errno gdb comand.

Now we can check the newly redirected file. /usr/sbin/lsof -p <PID> prints:

loop.sh <PID> truey    1u   REG   0,26        0 15008411 /home/truey/loop.out

If we want, we can redirect stderr to another file, if we want to using call close(2) and call open(...) again using a different file name.

Now the attached bash has to be released and we can quit gdb:

(gdb) detach
Detaching from program: /bin/bash, process <PID>
(gdb) q

If the script was stopped by gdb from an other terminal it continues to run. We can switch back to loop.sh's terminal. Now it does not write anything to the screen, but running and writing into the file. We have to put it into the background. So press ^Z.

^Z
[1]+  Stopped                 ./loop.sh

(Now we are in the same state as if ^Z was pressed at the beginning.)

Now we can check the state of the job:

$ ps -f 24522
UID        PID  PPID  C STIME TTY      STAT   TIME CMD
<UID>    <PID><PPID>  0 11:16 pts/36   S      0:00 /bin/bash ./loop.sh
$ jobs
[1]+  Stopped                 ./loop.sh

So process should be running in the background and detached from the terminal. The number in the jobs command's output in square brackets identifies the job inside bash. We can use in the following built in bash commands applying a '%' sign before the job number :

$ bg %1
[1]+ ./loop.sh &
$ disown -h %1
$ ps -f <PID>
UID        PID  PPID  C STIME TTY      STAT   TIME CMD
<UID>    <PID><PPID>  0 11:16 pts/36   S      0:00 /bin/bash ./loop.sh

And now we can quit from the calling bash. The process continues running in the background. If we quit its PPID become 1 (init(1) process) and the control terminal become unknown.

$ ps -f <PID>
UID        PID  PPID  C STIME TTY      STAT   TIME CMD
<UID>    <PID>     1  0 11:16 ?        S      0:00 /bin/bash ./loop.sh
$ /usr/bin/lsof -p <PID>
...
loop.sh <PID> truey    0u   CHR 136,36                38 /dev/pts/36 (deleted)
loop.sh <PID> truey    1u   REG   0,26     1127 15008411 /home/truey/loop.out
loop.sh <PID> truey    2u   CHR 136,36                38 /dev/pts/36 (deleted)

COMMENT

The gdb stuff can be automatized creating a file (e.g. loop.gdb) containing the commands and run gdb -q -x loop.gdb -p <PID>. My loop.gdb looks like this:

call close(1)
call open("loop.out", 01102, 0600)
# call close(2)
# call open("loop.err", 01102, 0600)
detach
quit

Or one can use the following one liner instead:

gdb -q -ex 'call close(1)' -ex 'call open("loop.out", 01102, 0600)' -ex detach -ex quit -p <PID>

I hope this is a fairly complete description of the solution.

1. A left shift by 1 position is analogous to multiplying by 2. A right shift is analogous to dividing by 2.
2. You can add in a loop to multiply. By picking the loop variable and the addition variable correctly, you can bound performance. Once you've explored that, you should use Peasant Multiplication

Here is a handy function for Swift 4.2, shows an image with title text:-

override func viewDidLoad() {

    super.viewDidLoad()

    //Sets the navigation title with text and image
    self.navigationItem.titleView = navTitleWithImageAndText(titleText: "Dean Stanley", imageName: "online")
}

func navTitleWithImageAndText(titleText: String, imageName: String) -> UIView {

    // Creates a new UIView
    let titleView = UIView()

    // Creates a new text label
    let label = UILabel()
    label.text = titleText
    label.sizeToFit()
    label.center = titleView.center
    label.textAlignment = NSTextAlignment.center

    // Creates the image view
    let image = UIImageView()
    image.image = UIImage(named: imageName)

    // Maintains the image's aspect ratio:
    let imageAspect = image.image!.size.width / image.image!.size.height

    // Sets the image frame so that it's immediately before the text:
    let imageX = label.frame.origin.x - label.frame.size.height * imageAspect
    let imageY = label.frame.origin.y

    let imageWidth = label.frame.size.height * imageAspect
    let imageHeight = label.frame.size.height

    image.frame = CGRect(x: imageX, y: imageY, width: imageWidth, height: imageHeight)

    image.contentMode = UIView.ContentMode.scaleAspectFit

    // Adds both the label and image view to the titleView
    titleView.addSubview(label)
    titleView.addSubview(image)

    // Sets the titleView frame to fit within the UINavigation Title
    titleView.sizeToFit()

    return titleView

}

With your ANDs you shouldn't have a FALSE value -2, until right at the end, e.g. with just 2 ANDs

=IF(AND(E2="In Play",F2="Closed"),3,IF(AND(E2="In Play",F2=" Suspended"),3,-2))

although it might be better with a combination of nested IFs and ANDs - try like this for the full formula:[Edited - thanks David]

=IF(E2="In Play",IF(F2="Closed",3,IF(F2="Suspended",2,IF(F2="Null",1))),IF(AND(E2="Pre-play",F2="Null"),-1,IF(AND(E2="Completed",F2="Closed"),2,IF(AND(E2="Pre-play",F2="Null"),3,-2))))

To avoid a long formula like the above you could create a table with all E2 possibilities in a column like K2:K5 and all F2 possibilities in a row like L1:N1 then fill in the required results in L2:N5 and use this formula

=INDEX($L$2:$N$5,MATCH(E2,$K$2:$K$5,0),MATCH(F2,$L$1:$N$1,0))

You must define states not equal to null..

@if (ViewBag.States!= null)
{
    @foreach (KeyValuePair<int, string> de in ViewBag.States)
    {
        value="@de.Key">@de.Value 
    }
}                                

show variables where Variable_name='hostname'; 

That could help you !!

I had similar problem before. But this was resolved when I started using hostname instead of IP address in my connection string.

Android has build-in Java API. Check out java.util.zip package.

The class ZipInputStream is what you should look into. Read ZipEntry from the ZipInputStream and dump it into filesystem/folder. Check similar example to compress into zip file.

Change localhost:8080 to localhost:3306.

A simpler way to wait is to use System.currentTimeMillis(), which returns the number of milliseconds since midnight on January 1, 1970 UTC. For example, to wait 5 seconds:

public static void main(String[] args) {
    //some code
    long original = System.currentTimeMillis();
    while (true) {
        if (System.currentTimeMillis - original >= 5000) {
            break;
        }
    }
    //more code after waiting
}

This way, you don't have to muck about with threads and exceptions. Hope this helps!

For anyone who must work with an older version of MySQL (pre-5.0 ish) you are unable to do sub-queries for this type of query. Here is the solution I was able to do and it seemed to work great.

SELECT MAX(d.id), d2.*, CONCAT(title,' ',forename,' ',surname) AS name
FROM customer AS c 
LEFT JOIN customer_data as d ON c.customer_id=d.customer_id 
LEFT JOIN customer_data as d2 ON d.id=d2.id
WHERE CONCAT(title, ' ', forename, ' ', surname) LIKE '%Smith%'
GROUP BY c.customer_id LIMIT 10, 20;

Essentially this is finding the max id of your data table joining it to the customer then joining the data table to the max id found. The reason for this is because selecting the max of a group doesn't guarantee that the rest of the data matches with the id unless you join it back onto itself.

I haven't tested this on newer versions of MySQL but it works on 4.0.30.

You don't need to use the background animate plugin if you just use separate values like this:

$('.pop').animate({
  'background-position-x': '10%',
  'background-position-y': '20%'
}, 10000, 'linear');

location.toString().replace(location.search, "")

An ORM (Object Relational Mapper) is a piece/layer of software that helps map your code Objects to your database.

Some handle more aspects than others...but the purpose is to take some of the weight of the Data Layer off of the developer's shoulders.

Here's a brief clip from Martin Fowler (Data Mapper):

Patterns of Enterprise Application Architecture Data Mappers

function isPrevDate() {
    alert("startDate is " + Startdate);
    if(Startdate.length != 0 && Startdate !='') {
        var start_date = Startdate.split('-');
        alert("Input date: "+ start_date);
        start_date=start_date[1]+"/"+start_date[2]+"/"+start_date[0];
        alert("start date arrray format " + start_date);
        var a = new Date(start_date);
        //alert("The date is a" +a);
        var today = new Date();
        var day = today.getDate();
        var mon = today.getMonth()+1;
        var year = today.getFullYear();
        today = (mon+"/"+day+"/"+year);
        //alert(today);
        var today = new Date(today);
        alert("Today: "+today.getTime());
        alert("a : "+a.getTime());
        if(today.getTime() > a.getTime() )
        {
            alert("Please select Start date in range");
            return false;
        } else {
            return true;
        }
    }
}

Depending on the schema/account you are using to connect to the database, I would suspect you are missing a grant to the account you are using to connect to the database.

Connect as PCT account in the database, then grant the account you are using select access for the table.

grant select on pi_int to Account_used_to_connect

Little Edit

Try adding

return new JavascriptResult() { Script = "alert('Successfully registered');" };

in place of

return RedirectToAction("Index");

I change upload method with images[] according to @Denmark.

    private function upload_files($path, $title, $files)
    {
        $config = array(
            'upload_path'   => $path,
            'allowed_types' => 'jpg|gif|png',
            'overwrite'     => 1,                       
        );

        $this->load->library('upload', $config);

        $images = array();

        foreach ($files['name'] as $key => $image) {
            $_FILES['images[]']['name']= $files['name'][$key];
            $_FILES['images[]']['type']= $files['type'][$key];
            $_FILES['images[]']['tmp_name']= $files['tmp_name'][$key];
            $_FILES['images[]']['error']= $files['error'][$key];
            $_FILES['images[]']['size']= $files['size'][$key];

            $fileName = $title .'_'. $image;

            $images[] = $fileName;

            $config['file_name'] = $fileName;

            $this->upload->initialize($config);

            if ($this->upload->do_upload('images[]')) {
                $this->upload->data();
            } else {
                return false;
            }
        }

        return $images;
    }

It should be

<input type="image" id="myimage" src="[...]" />

So "image" instead of "submit". It will still be a button which submits on click.

If your image is bigger than the button which is shown; let's say the image is 200x200 pixels; add this to your stylesheet:

#myimage {
    height: 200px;
    width: 200px;
}

or directly in the button tag:

<input type="image" id="myimage" style="height:200px;width:200px;" src="[...]" />

Note however that resizing the image like this might not yield ideal results; if e.g. your image is much smaller than you want it to be shown, you will see the single pixels; if on the other hand it is much bigger, you are wasting precious bandwidth of your users. So resizing the picture itself to the actual size is preferrable over rescaling via stylesheets!

This seems close to what you want:

#foo {_x000D_
  background: red;_x000D_
  max-height: 100px;_x000D_
  overflow-y: hidden;_x000D_
}_x000D_
_x000D_
.bar {_x000D_
  background: blue;_x000D_
  width: 100px;_x000D_
  height: 100px;_x000D_
  float: left;_x000D_
  margin: 1em;_x000D_
}

<div id="foo">_x000D_
  <div class="bar"></div>_x000D_
  <div class="bar"></div>_x000D_
  <div class="bar"></div>_x000D_
  <div class="bar"></div>_x000D_
  <div class="bar"></div>_x000D_
  <div class="bar"></div>_x000D_
</div>

Recently, I have seen this problem too. Below, you have my solution:

1. ping github.com, if ping failed. it is DNS error.
2. sudo vim /etc/resolv.conf, the add: nameserver 8.8.8.8 nameserver 8.8.4.4

Or it can be a genuine network issue. Restart your network-manager using sudo service network-manager restart or fix it up

I have just received this error after switching from HTTPS to SSH (for my origin remote). To fix, I simply ran the following command (for each repo):

ssh -T [email protected]

Upon receiving a successful response, I could fetch/push to the repo with ssh.

I took that command from Git's Testing your SSH connection guide, which is part of the greater Connecting to GitHub with with SSH guide.

Davids, I had the exact same problem as you. MVC is not intuitive and it seems when they designed it the kiddos didn't understand the purpose or importance of an intuitive querystring system for MVC.

Querystrings are not set in the routes at all (RouteConfig). They are add-on "extra" parameters to Actions in the Controller. This is very confusing as the Action parameters are designed to process BOTH paths AND Querystrings. If you added parameters and they did not work, add a second one for the querystring as so:

This would be your action in your Controller class that catches the ID (which is actually just a path set in your RouteConfig file as a typical default path in MVC):

public ActionResult Hello(int id)

But to catch querystrings an additional parameter in your Controller needs to be the added (which is NOT set in your RouteConfig file, by the way):

public ActionResult Hello(int id, string start, string end)

This now listens for "/Hello?start=&end=" or "/Hello/?start=&end=" or "/Hello/45?start=&end=" assuming the "id" is set to optional in the RouteConfig.cs file.

If you wanted to create a "custom route" in the RouteConfig file that has no "id" path, you could leave off the "id" or other parameter after the action in that file. In that case your parameters in your Action method in the controller would process just querystrings.

I found this extremely confusing myself so you are not alone! They should have designed a simple way to add querystring routes for both specific named strings, any querystring name, and any number of querystrings in the RouteConfig file configuration design. By not doing that it leaves the whole use of querystrings in MVC web applications as questionable, which is pretty bizarre since querystrings have been a stable part of the World Wide Web since the mid-1990's. :(

the mySql blob class has the following function :

blob.getBytes

use it like this:

//(assuming you have a ResultSet named RS)
Blob blob = rs.getBlob("SomeDatabaseField");

int blobLength = (int) blob.length();  
byte[] blobAsBytes = blob.getBytes(1, blobLength);

//release the blob and free up memory. (since JDBC 4.0)
blob.free();

I guess you can do this in 5 minute without any further IP/port forwarding, for presenting your local websites temporary.

All you need to do it, go to http://ngrok.com Download small tool extract and run that tool as administrator

Enter command
ngrok http 80

You will see it will connect to server and will create a temporary URL for you which you can share to your friend and let him browse localhost or any of its folder.

You can see detailed process here.
How do I access/share xampp or localhost website from another computer

All I know is a Clean does not do what "make clean" used to do - if I Clean a solution I would expect it delete obj and bin files/folders such that it builds like is was a fresh checkout of the source. In my experience though I often find times where a Clean and Build or Rebuild still produces strange errors on source that is known to compile and what is required is a manual deletion of the bin/obj folders, then it will build.

It helps me:

sudo nano /etc/postgresql/9.x/main/pg_hba.conf

and change this line:

Database administrative login by Unix domain socket
local   all             postgres                                md5

to

Database administrative login by Unix domain socket
local   all             postgres                                trust

2. Restart the server

   sudo service postgresql restart

3. Login into psql and set password

   psql -U postgres

ALTER USER postgres with password 'new password';

4. Again open the file pg_hba.conf and change this line:

Database administrative login by Unix domain socket
    local   all             postgres                                trust

to

    Database administrative login by Unix domain socket
    local   all             postgres                                md5

5. Restart the server

   sudo service postgresql restart

Same Error was coming with my code in Activity but not in Fragment. Showing constructor error for different line like new Intent( From.this, To.class) and new ArrayList<> etc.

Fixed using closing Android Studio and moving the repository to other location and opening the the project once again. Fixed the problem.

Seems like Android Studio building problem.

I had this problem suddenly crop up in Windows 7 with my Nexus One - somehow the USB drivers had been uninstalled. I ran android-sdk/SDK Manager.exe, checked Extras/Google USB Driver and installed it. Then I unplugged the phone and plugged it back in, and ran "adb devices" to confirm the phone was attached.

This doesn't work for all phones, just the ones listed here: http://developer.android.com/sdk/win-usb.html

The value of PYTHONHASHSEED might be used to initialize the hash values.

Try:

PYTHONHASHSEED python -c 'print(hash('http://stackoverflow.com'))'

You can check in all the below ways for a List

List<string> FilteredList = new List<string>();
//Comparing the two lists and gettings common elements.
FilteredList = a1.Intersect(a2, StringComparer.OrdinalIgnoreCase);

Putting the comment of EaterOfCode here as an answer.

grep itself also has the -c flag which just returns the count

So the command and output could look like this.

$ grep -Rl "curl" ./ -c
24

EDIT:

Although this answer might be shorter and thus might seem better than the accepted answer (that is using wc). I do not agree with this anymore. I feel like remembering that you can count lines by piping to wc -l is much more useful as you can use it with other programs than grep as well.

This stuff comes from ES file explorer

Just go into this app > settings

Then there is an option that says logging floating window, you just need to disable that and you will get rid of this infernal bubble for good

if you want to rotate inline elements, you should set the inline element to inline-block first.

i {
  display: inline-block;
}

i:hover {
  animation: rotate-btn .5s linear 3;
  -webkit-animation: rotate-btn .5s linear 3;
}

@keyframes rotate-btn {
  0% {
    transform: rotate(0);
  }
  100% {
    transform: rotate(-360deg);
  }
}

For me, it was a missing app domain. Go into the app, and make sure that you have the root of your site set up as an app domain. See screenshot.

I solved this by doing the following:

<body class="container-fluid">
    <div class="row">
        <div class="span6" style="float: none; margin: 0 auto;">
           ....
        </div>
    </div>
</body>

To retrieve it:

cat /proc/sys/kernel/threads-max

To set it:

echo 123456789 | sudo tee -a /proc/sys/kernel/threads-max

123456789 = # of threads

What you may want to do is include a script on all pages that does the following ... 1. find the youtube-iframe : searching for it by width and height by title or by finding www.youtube.com in its source. You can do that by ... - looping through the window.frames by a for-in loop and then filter out by the properties

1. inject jscript in the iframe of the current page adding the onYoutubePlayerReady must-include-function http://shazwazza.com/post/Injecting-JavaScript-into-other-frames.aspx

2. Add the event listeners etc..

Hope this helps

Why not keep things simple and use an adjacency matrix or an adjacency list?

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    Dialog dialog = new Dialog(getActivity(), android.R.style.Theme_Holo_Light);
    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);

    return dialog;
}

This solution applies a full screen theme on the dialog, which is similar to Chirag's setStyle in onCreate. A disadvantage is that savedInstanceState is not used.

You need to retrieve and disect the information into what you need.

while($row = mysql_fetch_array($result)) {
 echo "img src='",$row['filename'],"' width='175' height='200' />";
}

You can paste this js into your html file, remember put it before other js function

<script>
  // using jQuery
  function getCookie(name) {
    var cookieValue = null;
    if (document.cookie && document.cookie != '') {
      var cookies = document.cookie.split(';');
      for (var i = 0; i < cookies.length; i++) {
        var cookie = jQuery.trim(cookies[i]);
        // Does this cookie string begin with the name we want?
        if (cookie.substring(0, name.length + 1) == (name + '=')) {
          cookieValue = decodeURIComponent(cookie.substring(name.length + 1));
          break;
        }
      }
    }
    return cookieValue;
  }

  function csrfSafeMethod(method) {
    // these HTTP methods do not require CSRF protection
    return (/^(GET|HEAD|OPTIONS|TRACE)$/.test(method));
  }

  $(document).ready(function() {
    var csrftoken = getCookie('csrftoken');
    $.ajaxSetup({
      beforeSend: function(xhr, settings) {
        if (!csrfSafeMethod(settings.type) && !this.crossDomain) {
          xhr.setRequestHeader("X-CSRFToken", csrftoken);
        }
      }
    });
  });
</script>

You can mention your variable attributes in a property file and define environment specific property files like local.properties, production.propertied etc.

Now based on the environment, one of these property file can be read in one the listeners invoked at startup, like the ServletContextListener.

The property file will contain the the environment specific values for various keys.

Sample "local.propeties"

db.logsDataSource.url=jdbc:mysql://localhost:3306/logs
db.logsDataSource.username=root
db.logsDataSource.password=root

db.dataSource.url=jdbc:mysql://localhost:3306/main
db.dataSource.username=root
db.dataSource.password=root

Sample "production.properties"

db.logsDataSource.url=jdbc:mariadb://111.111.111.111:3306/logs
db.logsDataSource.username=admin
db.logsDataSource.password=xyzqer

db.dataSource.url=jdbc:mysql://111.111.111.111:3306/carsinfo
db.dataSource.username=admin
db.dataSource.password=safasf@mn

For using these properties file, you can make use of REsource as mentioned below

        PropertyPlaceholderConfigurer configurer = new PropertyPlaceholderConfigurer();
        ResourceLoader resourceLoader = new DefaultResourceLoader();

        Resource resource = resourceLoader.getResource("classpath:"+System.getenv("SERVER_TYPE")+"DB.properties");
        configurer.setLocation(resource);
        configurer.postProcessBeanFactory(beanFactory);

SERVER_TYPE can be defined as the environment variable with appropriate values for local and production environment.

With these changes the appplicationContext.xml will have the following changes

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
 <property name="driverClassName" value="com.mysql.jdbc.Driver" />
  <property name="url" value="${db.dataSource.url}" />
  <property name="username" value="${db.dataSource.username}" />
  <property name="password" value="${db.dataSource.password}" />

Hope this helps .

I was having the exact same issue, I triple checked the include paths, I also checked that pear was installed and everything looked OK and I was still getting the errors, after a few hours of going crazy looking at this I realized that in my script had this:

include_once "../Mail.php";

instead of:

include_once ("../Mail.php");

Yup, the stupid parenthesis was missing, but there was no generated error on this line of my script which was odd to me

First of all, the code you wrote isn't portable, even if you get it to work. Why use OS-specific functions when there is a perfectly platform-independent way of doing it? Here's a version that uses just a single header file and is portable to any platform that implements the C standard library.

#include <stdio.h>

int main(int argc, char **argv)
{
    FILE* sourceFile;
    FILE* destFile;
    char buf[50];
    int numBytes;

    if(argc!=3)
    {
        printf("Usage: fcopy source destination\n");
        return 1;
    }

    sourceFile = fopen(argv[1], "rb");
    destFile = fopen(argv[2], "wb");

    if(sourceFile==NULL)
    {
        printf("Could not open source file\n");
        return 2;
    }
    if(destFile==NULL)
    {
        printf("Could not open destination file\n");
        return 3;
    }

    while(numBytes=fread(buf, 1, 50, sourceFile))
    {
        fwrite(buf, 1, numBytes, destFile);
    }

    fclose(sourceFile);
    fclose(destFile);

    return 0;
}

EDIT: The glibc reference has this to say:

In general, you should stick with using streams rather than file descriptors, unless there is some specific operation you want to do that can only be done on a file descriptor. If you are a beginning programmer and aren't sure what functions to use, we suggest that you concentrate on the formatted input functions (see Formatted Input) and formatted output functions (see Formatted Output).

If you are concerned about portability of your programs to systems other than GNU, you should also be aware that file descriptors are not as portable as streams. You can expect any system running ISO C to support streams, but non-GNU systems may not support file descriptors at all, or may only implement a subset of the GNU functions that operate on file descriptors. Most of the file descriptor functions in the GNU library are included in the POSIX.1 standard, however.

You guys should checkout PyCharm! It is the first decent Django IDE.

Partial mocking using Mockito's spy method could be the solution to your problem, as already stated in the answers above. To some degree I agree that, for your concrete use case, it may be more appropriate to mock the DB lookup. From my experience this is not always possible - at least not without other workarounds - that I would consider as being very cumbersome or at least fragile. Note, that partial mocking does not work with ally versions of Mockito. You have use at least 1.8.0.

I would have just written a simple comment for the original question instead of posting this answer, but StackOverflow does not allow this.

Just one more thing: I really cannot understand that many times a question is being asked here gets comment with "Why you want to do this" without at least trying to understand the problem. Escpecially when it comes to then need for partial mocking there are really a lot of use cases that I could imagine where it would be useful. That's why the guys from Mockito provided that functionality. This feature should of course not be overused. But when we talk about test case setups that otherwise could not be established in a very complicated way, spying should be used.

I make one function like this:

function getTime()
{
    var date_obj = new Date();
    var date_obj_hours = date_obj.getHours();
    var date_obj_mins = date_obj.getMinutes();
    var date_obj_second = date_obj.getSeconds();

    var date_obj_time = "'"+date_obj_hours+":"+date_obj_mins+":"+date_obj_second+"'";
    return date_obj_time;
}

Then I use the jQuery UI datepicker like this:

$("#selector").datepicker( "option", "dateFormat", "yy-mm-dd "+getTime()+"" );

So, I get the value like this: 2010-10-31 12:41:57

Try this code:

 lblUDate.Text = DateTime.Parse(ds.Tables[0].Rows[0]["AppMstRealPaidTime"].ToString()).ToString("yyyy-MM-dd");

In windows " wmic process where processid="pid of the process running" get commandline " worked for me. The culprit was wrapper.exe process of webhuddle jboss soft.

This code will work. The answer from samplebias is almost correct, but you need a third change:

int addNodeBottom(int val, node *head){

    //create new node
    node *newNode = (node*)malloc(sizeof(node));

    if(newNode == NULL){
        fprintf(stderr, "Unable to allocate memory for new node\n");
        exit(-1);
    }

    newNode->value = val;
    newNode->next = NULL;  // Change 1

    //check for first insertion
    if(head->next == NULL){
        head->next = newNode;
        printf("added at beginning\n");
    }

    else
    {
        //else loop through the list and find the last
        //node, insert next to it
        node *current = head;
        while (true) { // Change 2
            if(current->next == NULL)
            {
                current->next = newNode;
                printf("added later\n");
                break; // Change 3
            }
            current = current->next;
        };
    }
    return 0;
}

Change 1: newNode->next must be set to NULL so we don't insert invalid pointers at the end of the list.

Change 2/3: The loop is changed to an endless loop that will be jumped out with break; when we found the last element. Note how while(current->next != NULL) contradicted if(current->next == NULL) before.

EDIT: Regarding the while loop, this way it is much better:

  node *current = head;
  while (current->next != NULL) {
    current = current->next;
  }
  current->next = newNode;
  printf("added later\n");

You ca also use Response.Write("alert('Error')");

What about this one? (doesn't require any extra libraries)

from datetime import date, timedelta
from calendar import monthrange

today = date.today()
month_later = date(today.year, today.month, monthrange(today.year, today.month)[1]) + timedelta(1)

size =1024;
alignment = 16;
aligned_size = size +(alignment -(size %  alignment));
mem = malloc(aligned_size);
memset_16aligned(mem, 0, 1024);
free(mem);

Hope this one is the simplest implementation, let me know your comments.

read the file and then do whatever you want java8 Files.lines(Paths.get("c://lines.txt")).collect(Collectors.toList());

You can't. and the reason is that they do not "live" in the same time. The Razor variables are "Server side variables" and they don't exist anymore after the page was sent to the "Client side".

When the server get a request for a view, it creates the view with only HTML, CSS and Javascript code. No C# code is left, it's all get "translated" to the client side languages.

The Javascript code DOES exist when the view is still on the server, but it's meaningless and will be executed by the browser only (Client side again).

This is why you can use Razor variables to change the HTML and Javascript but not vice versa. Try to look at your page source code (CTRL+U in most browsers), there will be no sign of C# code there.

In short:

1. The server gets a request.

2. The server creates or "takes" the view, then computes and translates all the C# code that was embedded in the view to CSS, Javascript, and HTML.

3. The server returns the client side version of the view to the browser as a response to the request. (there is no C# at this point anymore)

4. the browser renders the page and executes all the Javascript

this is what I have done. Check it out, hope it can help.

#!/bin/bash
#
# So something to show.
echo "UNO" >  UNO.txt
echo "DOS" >  DOS.txt
#
# Initialize Pid List
dPidLst=""
#
# Generate background processes
tail -f UNO.txt&

tail -f DOS.txt&

do
        echo killing $dPid. Process is still there.
        ps | grep $dPid
        kill $dPid
        ps | grep $dPid
        echo Just ran "'"ps"'" command, $dPid must not show again.
done

Then just run it as: ./bgkill.sh with proper permissions of course
