To set volume to 0

AudioManager audioManager;
audioManager = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);
audioManager.setStreamVolume(AudioManager.STREAM_MUSIC, 0, 0);

To set volume to full

AudioManager audioManager;
audioManager = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);
audioManager.setStreamVolume(AudioManager.STREAM_MUSIC, 20, 0);

the volume can be adjusted by changing the index value between 0 and 20

Exceding the maximum value of a long doesnt throw an exception, instead it cicles back. If you do this:

Long.MAX_VALUE + 1

you will notice that the result is the equivalent to Long.MIN_VALUE.

From here: java number exceeds long.max_value - how to detect?

I have tried to rename the repository on the web page:

1. Click on the top of the right pages that it's your avatar.
2. you can look at the icon of setting, click it and then you can find the Repositories under the Personal setting.
3. click the Repositories and enter your directories of Repositories, choose the Repository that you want to rename.
4. Then you will enter the chosen Repository and you will find the icon of setting is added to the top line, just click it and enter the new name then click Rename.

Done, so easy.

$rootScope.$on( "$routeChangeStart", function(event, next, current) {
  //..do something
  //event.stopPropagation();  //if you don't want event to bubble up 
});

I used to encounter this is my development, what I do is wrap my solution in a function to make it reusable in my environment, like this:

const sumArrayOfObject =(array, prop)=>array.reduce((sum, n)=>{return sum + n[prop]}, 0)

The accepted answer by @Meherzad only works if the data is in a particular order. It happens to work with the data from the OP question. In my case, I had to modify it to work with my data.

Note This only works when every record's "id" (col1 in the question) has a value GREATER THAN that record's "parent id" (col3 in the question). This is often the case, because normally the parent will need to be created first. However if your application allows changes to the hierarchy, where an item may be re-parented somewhere else, then you cannot rely on this.

This is my query in case it helps someone; note it does not work with the given question because the data does not follow the required structure described above.

select t.col1, t.col2, @pv := t.col3 col3
from (select * from table1 order by col1 desc) t
join (select @pv := 1) tmp
where t.col1 = @pv

The difference is that table1 is being ordered by col1 so that the parent will be after it (since the parent's col1 value is lower than the child's).

This is the sort of thing that sed is really good at: $ sed 's/[ \t]*$//'. Be aware the you will probably need to literally type a TAB character instead of \t for this to work.

From looking at the source code, it seems like the pg_stat_database query gives you the number of connections to the current database for all users. On the other hand, the pg_stat_activity query gives the number of connections to the current database for the querying user only.

There are two ways to go about doing this.

1. Create a state in the constructor that contains the text input. Attach an onChange event to the input box that updates state each time. Then onClick you could just alert the state object.

2. handleClick: function() { alert(this.refs.myInput.value); },

INSERT INTO Table1 (Column1) VALUES ('John''s')

Or you can use a stored procedure and pass the parameter as -

usp_Proc1 @Column1 = 'John''s'

If you are using an INSERT query and not a stored procedure, you'll have to escape the quote with two quotes, else its OK if you don't do it.

Maybe you use thing as $ ${: these chars should be quoted.

I use the current working directory ./ when building several apps off the same domain:

<base href="./">

On a side note, I use .htaccess to assist with my routing on page reload:

RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule .* index.html [L]

Use a single backspace after each character printf("hello wor\bl\bd\n");

You could use jsonic for to serialize pretty much anything to JSON:

https://github.com/OrrBin/Jsonic

Example:

class TestClass:
def __init__(self):
    self.x = 1
    self.y = 2

instance = TestClass()
s = serialize(instance): # instance s set to: {"x":1, "y":2}
d = deserialize(s) # d is a new class instance of TestClass

pythonic has some nice features like declaring class attributes transient and type safe deserialization.

(A few years late with the answer, but i think it might help others)

&& ; || are logical operators.... short circuit

& ; | are boolean logical operators.... Non-short circuit

Moving to differences in execution on expressions. Bitwise operators evaluate both sides irrespective of the result of left hand side. But in the case of evaluating expressions with logical operators, the evaluation of the right hand expression is dependent on the left hand condition.

For Example:

int i = 25;
int j = 25;
if(i++ < 0 && j++ > 0)
    System.out.println("OK");
System.out.printf("i = %d ; j = %d",i,j);

This will print i=26 ; j=25, As the first condition is false the right hand condition is bypassed as the result is false anyways irrespective of the right hand side condition.(short circuit)

int i = 25;
int j = 25;
if(i++ < 0 & j++ > 0)
    System.out.println("OK");
System.out.printf("i = %d ; j = %d",i,j);

But, this will print i=26; j=26,

If you are going to call relative.py directly and i.e. if you really want to import from a top level module you have to explicitly add it to the sys.path list.
Here is how it should work:

# Add this line to the beginning of relative.py file
import sys
sys.path.append('..')

# Now you can do imports from one directory top cause it is in the sys.path
import parent

# And even like this:
from parent import Parent

If you think the above can cause some kind of inconsistency you can use this instead:

sys.path.append(sys.path[0] + "/..")

sys.path[0] refers to the path that the entry point was ran from.

Another approach to this would be to download Jan Karel Pieterse's free Open XML class module from this page: Editing elements in an OpenXML file using VBA

With this added to your VBA project, you can unzip the Excel file, use VBA to modify the XML, then use the class to rezip the files.

jQuery allows you to specify if you want the ajax request to be asynchronous or not. You can simply make the ajax requests synchronous and then the rest of the code won't execute until they return.

For example:

jQuery.ajax({ 
    async: false,
    //code
});

You'll need tail. Some examples:

$ tail great-big-file.log
< Last 10 lines of great-big-file.log >

If you really need to SKIP a particular number of "first" lines, use

$ tail -n +<N+1> <filename>
< filename, excluding first N lines. >

That is, if you want to skip N lines, you start printing line N+1. Example:

$ tail -n +11 /tmp/myfile
< /tmp/myfile, starting at line 11, or skipping the first 10 lines. >

If you want to just see the last so many lines, omit the "+":

$ tail -n <N> <filename>
< last N lines of file. >

There is also a way to create XAML bindable SelectedItem property without using Interaction.Behaviors.

public static class BindableSelectedItemHelper
{
    #region Properties

    public static readonly DependencyProperty SelectedItemProperty = DependencyProperty.RegisterAttached("SelectedItem", typeof(object), typeof(BindableSelectedItemHelper),
        new FrameworkPropertyMetadata(null, OnSelectedItemPropertyChanged));

    public static readonly DependencyProperty AttachProperty = DependencyProperty.RegisterAttached("Attach", typeof(bool), typeof(BindableSelectedItemHelper), new PropertyMetadata(false, Attach));

    private static readonly DependencyProperty IsUpdatingProperty = DependencyProperty.RegisterAttached("IsUpdating", typeof(bool), typeof(BindableSelectedItemHelper));

    #endregion

    #region Implementation

    public static void SetAttach(DependencyObject dp, bool value)
    {
        dp.SetValue(AttachProperty, value);
    }

    public static bool GetAttach(DependencyObject dp)
    {
        return (bool)dp.GetValue(AttachProperty);
    }

    public static string GetSelectedItem(DependencyObject dp)
    {
        return (string)dp.GetValue(SelectedItemProperty);
    }

    public static void SetSelectedItem(DependencyObject dp, object value)
    {
        dp.SetValue(SelectedItemProperty, value);
    }

    private static bool GetIsUpdating(DependencyObject dp)
    {
        return (bool)dp.GetValue(IsUpdatingProperty);
    }

    private static void SetIsUpdating(DependencyObject dp, bool value)
    {
        dp.SetValue(IsUpdatingProperty, value);
    }

    private static void Attach(DependencyObject sender, DependencyPropertyChangedEventArgs e)
    {
        TreeListView treeListView = sender as TreeListView;
        if (treeListView != null)
        {
            if ((bool)e.OldValue)
                treeListView.SelectedItemChanged -= SelectedItemChanged;

            if ((bool)e.NewValue)
                treeListView.SelectedItemChanged += SelectedItemChanged;
        }
    }

    private static void OnSelectedItemPropertyChanged(DependencyObject sender, DependencyPropertyChangedEventArgs e)
    {
        TreeListView treeListView = sender as TreeListView;
        if (treeListView != null)
        {
            treeListView.SelectedItemChanged -= SelectedItemChanged;

            if (!(bool)GetIsUpdating(treeListView))
            {
                foreach (TreeViewItem item in treeListView.Items)
                {
                    if (item == e.NewValue)
                    {
                        item.IsSelected = true;
                        break;
                    }
                    else
                       item.IsSelected = false;                        
                }
            }

            treeListView.SelectedItemChanged += SelectedItemChanged;
        }
    }

    private static void SelectedItemChanged(object sender, RoutedEventArgs e)
    {
        TreeListView treeListView = sender as TreeListView;
        if (treeListView != null)
        {
            SetIsUpdating(treeListView, true);
            SetSelectedItem(treeListView, treeListView.SelectedItem);
            SetIsUpdating(treeListView, false);
        }
    }
    #endregion
}

You can then use this in your XAML as:

<TreeView  helper:BindableSelectedItemHelper.Attach="True" 
           helper:BindableSelectedItemHelper.SelectedItem="{Binding SelectedItem, Mode=TwoWay}">

Problem is about too long setup file name. Change setup.exe parent folder name(short a name). And try it!.

Easiest way I find is to:

1. Right click project

2. Debug as -> Maven build ...

3. In the goals field put -Dmaven.surefire.debug test

4. In the parameters put a new parameter called forkCount with a value of 0 (previously was forkMode=never but it is deprecated and doesn't work anymore)

Set your breakpoints down and run this configuration and it should hit the breakpoint.

In the extreme case of not knowing which callback is attached to a window listener, an handler can be wrapper around window addEventListener and a variable can store ever listeners to properly remove each one of those through a removeAllEventListener('scroll') for example.

var listeners = {};

var originalEventListener = window.addEventListener;
window.addEventListener = function(type, fn, options) {
    if (!listeners[type])
        listeners[type] = [];

    listeners[type].push(fn);
    return originalEventListener(type, fn, options);
}

var removeAllEventListener = function(type) {
    if (!listeners[type] || !listeners[type].length)
        return;

    for (let i = 0; i < listeners[type].length; i++)
        window.removeEventListener(type, listeners[type][i]);
}

You can use Substring:

string b = a.Substring(0,3);

The use-case for CORS is simple. Imagine the site alice.com has some data that the site bob.com wants to access. This type of request traditionally wouldn’t be allowed under the browser’s same origin policy. However, by supporting CORS requests, alice.com can add a few special response headers that allows bob.com to access the data. In order to understand it well, please visit this nice tutorial.. How to solve the issue of CORS

Wow so many answers already.. Im pretty sure this gets buried. Even so I figured this might be useful for some.

I wasn't fully satisfied with the chosen answers as in ES6 it doesn't work well with default values. And it also does not provide the default value information. I also wanted a lightweight function that does not depend on an external lib.

This function is very useful for debugging purposes, for example: logging called function with its params, default param values and arguments.

I spent some time on this yesterday, cracking the right RegExp to solve this issue and this is what I came up with. It works very well and I'm very pleased with the outcome:

As you can tell some of the parameter names disappear because the Babel transpiler removes them from the function. If you would run this in the latest NodeJS it works as expected (The commented results are from NodeJS).

Another note, as stated in the comment is that is does not work with inlined arrow functions as a default value. This simply makes it far to complex to extract the values using a RegExp.

Please let me know if this was useful for you! Would love to hear some feedback!

colrm x

For example, if you need the first 100 characters:

cat file |colrm 101 

It's been around for years and is in most linux's and bsd's (freebsd for sure), usually by default. I can't remember ever having to type apt-get install colrm.

You could make a method:

public byte[] toBytes(char[] data) {
byte[] toRet = new byte[data.length];
for(int i = 0; i < toRet.length; i++) {
toRet[i] = (byte) data[i];
}
return toRet;
}

Hope this helps

Try this:

// this will fix old browsers
if (!Array.prototype.indexOf) {
  Array.prototype.indexOf = function(value) {
    for (var i = 0; i < this.length; i++) {
      if (this[i] === value) {
        return i;
      }
    }

    return -1;
  }
}

// example
if ([1, 2, 3].indexOf(2) != -1) {
  // yay!
}

By default, it uses YAFFS - Yet Another Flash File System.

always use with statement like ;WITH then you'll never get this error. The WITH command required a ; between it and any previous command, by always using ;WITH you'll never have to remember to do this.

see WITH common_table_expression (Transact-SQL), from the section Guidelines for Creating and Using Common Table Expressions:

When a CTE is used in a statement that is part of a batch, the statement before it must be followed by a semicolon.

When calling finish() on an activity, the method onDestroy() is executed. This method can do things like:

1. Dismiss any dialogs the activity was managing.
2. Close any cursors the activity was managing.
3. Close any open search dialog

Also, onDestroy() isn't a destructor. It doesn't actually destroy the object. It's just a method that's called based on a certain state. So your instance is still alive and very well* after the superclass's onDestroy() runs and returns.Android keeps processes around in case the user wants to restart the app, this makes the startup phase faster. The process will not be doing anything and if memory needs to be reclaimed, the process will be killed

Share Files, Folders or Drives Between Host and Hyper-V Virtual Machine

Prerequisites

1. Ensure that Enhanced session mode settings are enabled on the Hyper-V host.

   Start Hyper-V Manager, and in the Actions section, select "Hyper-V Settings".

   

   Make sure that enhanced session mode is allowed in the Server section. Then, make sure that the enhanced session mode is available in the User section.

   

2. Enable Hyper-V Guest Services for your virtual machine

   Right-click on Virtual Machine > Settings. Select the Integration Services in the left-lower corner of the menu. Check Guest Service and click OK.

   

Steps to share devices with Hyper-v virtual machine:

1. Start a virtual machine and click Show Options in the pop-up windows.

   

   Or click "Edit Session Settings..." in the Actions panel on the right

   

   It may only appear when you're (able to get) connected to it. If it doesn't appear try Starting and then Connecting to the VM while paying close attention to the panel in the Hyper-V Manager.

2. View local resources. Then, select the "More..." menu.

   

3. From there, you can choose which devices to share. Removable drives are especially useful for file sharing.

   

4. Choose to "Save my settings for future connections to this virtual machine".

   

5. Click Connect. Drive sharing is now complete, and you will see the shared drive in this PC > Network Locations section of Windows Explorer after using the enhanced session mode to sigh to the VM. You should now be able to copy files from a physical machine and paste them into a virtual machine, and vice versa.

Installing Microsoft Visual C++ 2010 Service Pack 1 Compiler Update for the Windows SDK 7.1 fixed the MSB4019 errors that I was getting building on Windows7 x64.

The readme of that update states that the recommended order is

2. Windows SDK 7.1
3. Visual Studio 2010 SP1
4. Visual C++ 2010 SP1 Compiler Update for the Windows SDK 7.1

If you are using a data source, here's another way to do it without code behind.

Note the following key points:

• The ListItem of Value="0" is on the source page, not added in code
• The ListItem in the source will be overwritten if you don't include AppendDataBoundItems="true" in the DropDownList
• InitialValue="0" tells the validator that this is the value that should fire that validator (as pointed out in other answers)

Example:

<asp:DropDownList ID="ddlType" runat="server" DataSourceID="sdsType"
                  DataValueField="ID" DataTextField="Name" AppendDataBoundItems="true">
    <asp:ListItem Value="0" Text="--Please Select--" Selected="True"></asp:ListItem>
</asp:DropDownList>
<asp:RequiredFieldValidator ID="rfvType" runat="server" ControlToValidate="ddlType" 
                            InitialValue="0" ErrorMessage="Type required"></asp:RequiredFieldValidator>
<asp:SqlDataSource ID="sdsType" runat="server" 
                   ConnectionString='<%$ ConnectionStrings:TESTConnectionString %>'
                   SelectCommand="SELECT ID, Name FROM Type"></asp:SqlDataSource>

You should always include the table name in the SQL query when dealing with associations.

Indeed if another table has the user_id column and you join both tables, you will have an ambiguous column name in the SQL query (i.e. troubles).

So, in your example:

GroupUser.where("groups_users.user_id != ?", me)

Or a bit more verbose:

GroupUser.where("#{table_name}.user_id IS NOT ?", me)

Note that if you are using a hash, you don't need to worry about that because Rails takes care of it for you:

GroupUser.where(user: me)

In Rails 4, as said by @dr4k3, the query method not has been added:

GroupUser.where.not(user: me)

I tried this as a best guess, but no luck:

It looks right to me. Have you tried setting a message severity explicitly? Also I believe the ID needs to be the same as that of a component (i.e., you'd need to use newPassword1 or newPassword2, if those are your IDs, and not newPassword as you had in the example).

FacesContext.getCurrentInstance().addMessage("newPassword1", 
                    new FacesMessage(FacesMessage.SEVERITY_ERROR, "Error Message"));

Then use <h:message for="newPassword1" /> to display the error message on the JSF page.

The problem you're running into is that most background thread / worker APIs will create the thread in a Multithreaded Apartment state. The error message indicates that the control requires the thread be a Single Threaded Apartment.

You can work around this by creating a thread yourself and specifying the STA apartment state on the thread.

var t = new Thread(MyThreadStartMethod);
t.SetApartmentState(ApartmentState.STA);
t.Start();

As already said by Jordão, just negate it:

if (!(id in tutorTimes)) { ... }

Note: The above test if tutorTimes has a property with the name specified in id, anywhere in the prototype chain. For example "valueOf" in tutorTimes returns true because it is defined in Object.prototype.

If you want to test if a property doesn't exist in the current object, use hasOwnProperty:

if (!tutorTimes.hasOwnProperty(id)) { ... }

Or if you might have a key that is hasOwnPropery you can use this:

if (!Object.prototype.hasOwnProperty.call(tutorTimes,id)) { ... }

Empty string is a pair of double-quotes/"", we can just test the length:

set ARG=%1
if not defined ARG goto nomore

set CHAR=%ARG:~2,1%
if defined CHAR goto goon

then test it's 2 characters against double-quotes:

if ^%ARG:~1,1% == ^" if ^%ARG:~0,1% == ^" goto blank
::else
goto goon

Here's a batch script you can play with. I think it properly catches the empty string.

This is just an example, you just need to customize 2 (or 3?) steps above according to your script.

@echo off
if not "%OS%"=="Windows_NT" goto EOF
:: I guess we need enableExtensions, CMIIW
setLocal enableExtensions
set i=0
set script=%0

:LOOP
set /a i=%i%+1

set A1=%1
if not defined A1 goto nomore

:: Assumption:
:: Empty string is (exactly) a pair of double-quotes ("")

:: Step out if str length is more than 2
set C3=%A1:~2,1%
if defined C3 goto goon

:: Check the first and second char for double-quotes
:: Any characters will do fine since we test it *literally*
if ^%A1:~1,1% == ^" if ^%A1:~0,1% == ^" goto blank
goto goon

:goon
echo.args[%i%]: [%1]
shift
goto LOOP

:blank
echo.args[%i%]: [%1] is empty string
shift
goto LOOP

:nomore
echo.
echo.command line:
echo.%script% %*

:EOF

This torture test result:

.test.bat :: ""  ">"""bl" " "< "">"  (")(") "" :: ""-"  " "( )"">\>" ""
args[1]: [::]
args[2]: [""] is empty string
args[3]: [">"""bl" "]
args[4]: ["< "">"]
args[5]: [(")(")]
args[6]: [""] is empty string
args[7]: [::]
args[8]: [""-"  "]
args[9]: ["( )"">\>"]
args[10]: [""] is empty string

command line:
.test.bat :: ""  ">"""bl" " "< "">"  (")(") "" :: ""-"  " "( )"">\>" ""

IIS7 defines a defaultDocument section in its configuration files which can be found in the %WinDir%\System32\InetSrv\Config folder. Most likely, the file index.aspx is already defined as a default document in one of IIS7's configuration files and you are adding it again in your web.config.

I suspect that removing the line <add value="index.aspx" />

from the defaultDocument/files section will fix your issue.

The defaultDocument section of your config will look like:

<defaultDocument>
  <files>
    <remove value="default.aspx" />
    <remove value="index.html" />
    <remove value="iisstart.htm" />
    <remove value="index.htm" />
    <remove value="Default.asp" />
    <remove value="Default.htm" />
  </files>
</defaultDocument>

Note that index.aspx will still appear in the list of default documents for your site in the IIS manager.

For more information about IIS7 configuration, click here.

In this line:

const char* cstr2 = ss.str().c_str();

ss.str() will make a copy of the contents of the stringstream. When you call c_str() on the same line, you'll be referencing legitimate data, but after that line the string will be destroyed, leaving your char* to point to unowned memory.

This error occurs when you define the response as application/json and you are getting a HTML as a response. Basically, this happened when you are writing server side script for specific url with a response of JSON but the error format is in HTML.

int is nothing but an interruption i.e the processor will put its current execution to hold.

0x80 is nothing but a system call or the kernel call. i.e the system function will be executed.

To be specific 0x80 represents rt_sigtimedwait/init_module/restart_sys it varies from architecture to architecture.

Here is how to do a quick check to see if n.fn.init[0] is caused by your DOM-elements not loading in time. Delay your selector function by wrapping it in setTimeout function like this:

function timeout(){ 

    ...your selector function that returns n.fn.init[0] goes here...

}

setTimeout(timeout, 5000)

This will cause your selector function to execute with a 5 second delay, which should be enough for pretty much anything to load.

This is just a coarse hack to check if DOM is ready for your selector function or not. This is not a (permanent) solution.

The preferred ways to check if the DOM is loaded before executing your function are as follows:

1) Wrap your selector function in

$(document).ready(function(){  ... your selector function...  };

2) If that doesn't work, use DOMContentLoaded

3) Try window.onload, which waits for all the images to load first, so its least preferred

window.onload = function () {  ... your selector function...  }

4) If you are waiting for a library to load that loads in several steps or has some sort of delay of its own, then you might need some complicated custom solution. This is what happened to me with "MathJax" library. This question discusses how to check when MathJax library loaded its DOM elements, if it is of any help.

5) Finally, you can stick with hard-coded setTimeout function, making it maybe 1-3 seconds. This is actually the very least preferred method in my opinion.

This list of fixes is probably far from perfect so everyone is welcome to edit it.

You could check if $profitloss < 0

if ($profitloss < 0):
    echo "Less than 0\n";
endif;

As mentioned

git add -u

stages the removed files for deletion, BUT ALSO modified files for update.

To unstage the modified files you can do

git reset HEAD <path>

if you like to keep your commits organized and clean.
NOTE: This could also unstage the deleted files, so careful with those wildcards.

You are using the wrong iteration counter, replace inp.charAt(i) with inp.charAt(j).

Where a is the slice, and i is the index of the element you want to delete:

a = append(a[:i], a[i+1:]...)

... is syntax for variadic arguments in Go.

Basically, when defining a function it puts all the arguments that you pass into one slice of that type. By doing that, you can pass as many arguments as you want (for example, fmt.Println can take as many arguments as you want).

Now, when calling a function, ... does the opposite: it unpacks a slice and passes them as separate arguments to a variadic function.

So what this line does:

a = append(a[:0], a[1:]...)

is essentially:

a = append(a[:0], a[1], a[2])

Now, you may be wondering, why not just do

a = append(a[1:]...)

Well, the function definition of append is

func append(slice []Type, elems ...Type) []Type

So the first argument has to be a slice of the correct type, the second argument is the variadic, so we pass in an empty slice, and then unpack the rest of the slice to fill in the arguments.

mkmf is part of the ruby1.9.1-dev package. This package contains the header files needed for extension libraries for Ruby 1.9.1. You need to install the ruby1.9.1-dev package by doing:

sudo apt-get install ruby1.9.1-dev

Then you can install Rails as per normal.

Generally it's easier to just do:

sudo apt-get install ruby-dev

Changing the actual environment variables can be done by using the env: namespace / drive information. For example, this code will update the path environment variable:

$env:Path = "SomeRandomPath";             (replaces existing path) 
$env:Path += ";SomeRandomPath"            (appends to existing path)

There are ways to make environment settings permanent, but if you are only using them from PowerShell, it's probably a lot better to use your profile to initiate the settings. On startup, PowerShell will run any .ps1 files it finds in the WindowsPowerShell directory under My Documents folder. Typically you have a profile.ps1 file already there. The path on my computer is

C:\Users\JaredPar\Documents\WindowsPowerShell\profile.ps1

What you're using in the python code is called a list in python, and it's tottaly different from R vectors, if i get what you wanna do:

# you can do like this if you'll put them manually  
v <- c("a", "b", "c")

# if your values are in a list 
v <- as.vector(your_list)

# if you just need to append
v <- append(v, value, after=length(v))

For example:

sql = ("select field1, field2, field3, field4 "
       "from table "
       "where condition1={} "
       "and condition2={}").format(1, 2)

Output: 'select field1, field2, field3, field4 from table
         where condition1=1 and condition2=2'

If the value of the condition should be a string, you can do it like this:

sql = ("select field1, field2, field3, field4 "
       "from table "
       "where condition1='{0}' "
       "and condition2='{1}'").format('2016-10-12', '2017-10-12')

Output: "select field1, field2, field3, field4 from table where
         condition1='2016-10-12' and condition2='2017-10-12'"

Another option would be to build it automatically using Eclipse. Of course if you have continuous integration environment Ant or Maven is recommended. The export alternative is not very convenient because you have to configure every time the export properties.

STEPS:

1. Enable "Project Archives" support; this might depend on your project (I used it on Java EE/Web project). Right-click project root directory; Configure -> Add Project Archives Support.

2. Go and create a new archive in the "Project Archives" top dir. You have only jar option, but name you archive *.war.

3. Configure Fileset-s, i.e what files to be included. Typical is to configure two filesets similar how the Web Deployment Assembly (project property) is configured.

   • copy /WebContent to /
   • copy /build/classes to WEB-INF/classes (create this fileset after you define the WEB-INF/classes directory in the archive)

4. You might need to tweek the fileset exclude property depending where you placed some of the config files or you might need more filesets, but the idea is that once you configured this you don't need to change it.

5. Build the archive manually or publish directly to server; but is also automatically built for you by Eclipse

I feel like properties are about letting you get the overhead of writing getters and setters only when you actually need them.

Java Programming culture strongly advise to never give access to properties, and instead, go through getters and setters, and only those which are actually needed. It's a bit verbose to always write these obvious pieces of code, and notice that 70% of the time they are never replaced by some non-trivial logic.

In Python, people actually care for that kind of overhead, so that you can embrace the following practice :

• Do not use getters and setters at first, when if they not needed
• Use @property to implement them without changing the syntax of the rest of your code.

I haven't been able to find much evidence as to why you would want to choose C over C++.

You can hardly call what I'm about to say evidence; it's just my opinion.

People like C because it fits nicely inside the mind of the prgrammer.

There are many complex rules of C++ [when do you need virtual destructors, when can you call virtual methods in a constructor, how does overloading and overriding interact, ...], and to master them all takes a lot of effort. Also, between references, operator overloading and function overloading, understanding a piece of code can require you to understand other code that may or may not be easy to find.

A different question in why organizations would prefer C over C++. I don't know that, I'm just a people ;-)

In the defense of C++, it does bring valuable features to the table; the one I value most is probably parametric('ish) polymorphism, though: operations and types that takes one or more types as arguments.

http://api.football-data.org/index is free and useful. The API is in active development, stable and recently the first versioned release called alpha was put online. Check the blog section to follow updates and changes.

This can also be achieved with jsp:include. Chad Darby explains well here in this video https://www.youtube.com/watch?v=EWbYj0qoNHo

I encountered the same problem with converting a ByteArrayOutputStream to a ByteArrayInputStream and solved it by using a derived class from ByteArrayOutputStream which is able to return a ByteArrayInputStream that is initialized with the internal buffer of the ByteArrayOutputStream. This way no additional memory is used and the 'conversion' is very fast:

package info.whitebyte.utils;
import java.io.ByteArrayInputStream;
import java.io.ByteArrayOutputStream;

/**
 * This class extends the ByteArrayOutputStream by 
 * providing a method that returns a new ByteArrayInputStream
 * which uses the internal byte array buffer. This buffer
 * is not copied, so no additional memory is used. After
 * creating the ByteArrayInputStream the instance of the
 * ByteArrayInOutStream can not be used anymore.
 * <p>
 * The ByteArrayInputStream can be retrieved using <code>getInputStream()</code>.
 * @author Nick Russler
 */
public class ByteArrayInOutStream extends ByteArrayOutputStream {
    /**
     * Creates a new ByteArrayInOutStream. The buffer capacity is
     * initially 32 bytes, though its size increases if necessary.
     */
    public ByteArrayInOutStream() {
        super();
    }

    /**
     * Creates a new ByteArrayInOutStream, with a buffer capacity of
     * the specified size, in bytes.
     *
     * @param   size   the initial size.
     * @exception  IllegalArgumentException if size is negative.
     */
    public ByteArrayInOutStream(int size) {
        super(size);
    }

    /**
     * Creates a new ByteArrayInputStream that uses the internal byte array buffer 
     * of this ByteArrayInOutStream instance as its buffer array. The initial value 
     * of pos is set to zero and the initial value of count is the number of bytes 
     * that can be read from the byte array. The buffer array is not copied. This 
     * instance of ByteArrayInOutStream can not be used anymore after calling this
     * method.
     * @return the ByteArrayInputStream instance
     */
    public ByteArrayInputStream getInputStream() {
        // create new ByteArrayInputStream that respects the current count
        ByteArrayInputStream in = new ByteArrayInputStream(this.buf, 0, this.count);

        // set the buffer of the ByteArrayOutputStream 
        // to null so it can't be altered anymore
        this.buf = null;

        return in;
    }
}

I put the stuff on github: https://github.com/nickrussler/ByteArrayInOutStream

The relationship between automatically generated sequences ( such as those created for SERIAL columns ) and the parent table is modelled by the sequence owner attribute.

You can modify this relationship using the OWNED BY clause of the ALTER SEQUENCE commmand

e.g. ALTER SEQUENCE foo_id OWNED by foo_schema.foo_table

to set it to be linked to the table foo_table

or ALTER SEQUENCE foo_id OWNED by NONE

to break the connection between the sequence and any table

The information about this relationship is stored in the pg_depend catalogue table.

the joining relationship is the link between pg_depend.objid -> pg_class.oid WHERE relkind = 'S' - which links the sequence to the join record and then pg_depend.refobjid -> pg_class.oid WHERE relkind = 'r' , which links the join record to the owning relation ( table )

This query returns all the sequence -> table dependencies in a database. The where clause filters it to only include auto generated relationships, which restricts it to only display sequences created by SERIAL typed columns.

WITH fq_objects AS (SELECT c.oid,n.nspname || '.' ||c.relname AS fqname , 
                           c.relkind, c.relname AS relation 
                    FROM pg_class c JOIN pg_namespace n ON n.oid = c.relnamespace ),

     sequences AS (SELECT oid,fqname FROM fq_objects WHERE relkind = 'S'),  
     tables    AS (SELECT oid, fqname FROM fq_objects WHERE relkind = 'r' )  
SELECT
       s.fqname AS sequence, 
       '->' as depends, 
       t.fqname AS table 
FROM 
     pg_depend d JOIN sequences s ON s.oid = d.objid  
                 JOIN tables t ON t.oid = d.refobjid  
WHERE 
     d.deptype = 'a' ;

If you're in local machine then use this command

/usr/local/mysql/bin/mysqldump -h127.0.0.1 --port = 3306 -u [username] -p [password] --databases [db_name] --tables [tablename] > /to/path/tablename.sql;

For remote machine, use below one

/usr/local/mysql/bin/mysqldump -h [remoteip] --port = 3306 -u [username] -p [password] --databases [db_name] --tables [tablename] > /to/path/tablename.sql;

Once you clear the interval using clearInterval you could setInterval once again. And to avoid repeating the callback externalize it as a separate function:

var ticker = function() {
    console.log('idle');
};

then:

var myTimer = window.setInterval(ticker, 4000);

then when you decide to restart:

window.clearInterval(myTimer);
myTimer = window.setInterval(ticker, 4000);

I got the error using TFS, my AssemblyInfo wasn't mapped in the branch I was working on.

Found the problem and couldn't find the solution until tried this.

1. Open Visual Basic from Developer tab (OR right-click at any sheet and click 'View code')
2. At upper left panel, select 'ThisWorkbook'
3. At lower left panel, find 'ForceFullCalculation' attribute
4. Change it from 'False' to 'True' and save it

I'm not sure if this has any side-effect, but it is work for me now.

If you get the context via the parameter list of Configure in Startup.cs, You can instead do this:

public void Configure(IApplicationBuilder app, IHostingEnvironment env,  LoggerFactory loggerFactory,
    ApplicationDbContext context)
 {
      context.Database.Migrate();
      ...

Try the following:

 for i in {1..600}; do echo wget http://example.com/search/link$(($i % 5)); done

The $(( )) syntax does an arithmetic evaluation of the contents.

You can use an array of pointer to (homogeneous) member data to enable a dual, named-member (i.e. x.data) and array-subscript (i.e. x[idx]) interface.

#include <cassert>
#include <cstddef>

struct vector3 {
    float x;
    float y;
    float z;

    float& operator[](std::size_t idx) {
        static float vector3::*component[3] = {
            &vector3::x, &vector3::y, &vector3::z
        };
        return this->*component[idx];
    }
};

int main()
{
    vector3 v = { 0.0f, 1.0f, 2.0f };

    assert(&v[0] == &v.x);
    assert(&v[1] == &v.y);
    assert(&v[2] == &v.z);

    for (std::size_t i = 0; i < 3; ++i) {
        v[i] += 1.0f;
    }

    assert(v.x == 1.0f);
    assert(v.y == 2.0f);
    assert(v.z == 3.0f);

    return 0;
}

If Not temp_rst1 Is Nothing Then ...

Maybe this is too simple an answer to help a lot of people, but worth trying if you haven't: Do a "vagrant halt" instead of a "vagrant suspend" then restart the VM with "vagrant up".

I think my problem was due to some "kworker" process getting buggy and constantly timing out in the VM and so doing a hard reboot seemed to reload the process correctly whereas a save and restore was just restoring the broken process in its broken state.

I solved the problem (How to connect multiple database using spring and Hibernate) in this way, I hope it will help :)

NOTE: I have added the relevant code, kindly make the dao with the help of impl I used in the below mentioned code.

These lines are your problem (or at least one of your problems, if there are more):

private static string s_bstCommonAppData = Path.Combine(s_commonAppData, "XXXX");
private static string s_bstUserDataDir = Path.Combine(s_bstCommonAppData, "UserData");
private static string s_commonAppData = Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData);

You reference some static members in the initializers for other static members. This is a bad idea, as the compiler doesn't know in which order to initialize them. The result is that during the initialization of s_bstCommonAppData, the dependent field s_commonAppData has not yet been initialized, so you are calling Path.Combine(null, "XXXX") and this method does not accept null arguments.

You can fix this by making sure that fields used in the initialization of other fields are declared first:

private static string s_commonAppData = Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData);
private static string s_bstCommonAppData = Path.Combine(s_commonAppData, "XXXX");
private static string s_bstUserDataDir = Path.Combine(s_bstCommonAppData, "UserData");

Or use a static constructor to explicitly order the assignments:

private static string s_bstCommonAppData;
private static string s_bstUserDataDir;
private static string s_commonAppData;

static Logger()
{
    s_commonAppData = Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData);
    s_bstCommonAppData = Path.Combine(s_commonAppData, "XXXX");
    s_bstUserDataDir = Path.Combine(s_bstCommonAppData, "UserData");
}

You need to implement a custom Authenticator

import javax.mail.Authenticator;
import javax.mail.PasswordAuthentication;


class GMailAuthenticator extends Authenticator {
     String user;
     String pw;
     public GMailAuthenticator (String username, String password)
     {
        super();
        this.user = username;
        this.pw = password;
     }
    public PasswordAuthentication getPasswordAuthentication()
    {
       return new PasswordAuthentication(user, pw);
    }
}

Now use it in the Session

Session session = Session.getInstance(props, new GMailAuthenticator(username, password));

I listed dates of 2 Weeks later. You can use variable @period OR function datediff(dd, @date_start, @date_end)

declare @period INT, @date_start datetime, @date_end datetime, @i int;

set @period = 14
set @date_start = convert(date,DATEADD(D, -@period, curent_timestamp))
set @date_end = convert(date,current_timestamp)
set @i = 1

create table #datesList(dts datetime)
insert into #datesList values (@date_start)
while @i <= @period
    Begin
        insert into #datesList values (dateadd(d,@i,@date_start))
        set @i = @i + 1
    end
select cast(dts as DATE) from #datesList
Drop Table #datesList

For python version 2.x you can simply use

• pip install pillow

But for python version 3.X you need to specify

• (sudo) pip3 install pillow

when you enter pip in bash hit tab and you will see what options you have

If you have root access to the server where mysql is running you should stop the mysql server using this command

sudo service mysql stop

Now start mysql using this command

sudo /usr/sbin/mysqld --skip-grant-tables  --skip-networking &

Now you can login to mysql using

sudo mysql
FLUSH PRIVILEGES;
SET PASSWORD FOR 'root'@'localhost' = PASSWORD('MyNewPass');

Full instructions can be found here http://www.techmatterz.com/recover-mysql-root-password/

You are facing issue in

 s1.name="Paolo";

because, in the LHS, you're using an array type, which is not assignable.

To elaborate, from C11, chapter §6.5.16

assignment operator shall have a modifiable lvalue as its left operand.

and, regarding the modifiable lvalue, from chapter §6.3.2.1

A modifiable lvalue is an lvalue that does not have array type, [...]

You need to use strcpy() to copy into the array.

That said, data s1 = {"Paolo", "Rossi", 19}; works fine, because this is not a direct assignment involving assignment operator. There we're using a brace-enclosed initializer list to provide the initial values of the object. That follows the law of initialization, as mentioned in chapter §6.7.9

Each brace-enclosed initializer list has an associated current object. When no designations are present, subobjects of the current object are initialized in order according to the type of the current object: array elements in increasing subscript order, structure members in declaration order, and the first named member of a union.[....]

In addition to the other answers, there is also the TimeUnit class which allows you to convert one time duration to another. For example, to find out how many milliseconds make up one day:

TimeUnit.MILLISECONDS.convert(1, TimeUnit.DAYS); //gives 86400000

Note that this method takes a long, so if you have a fraction of a day, you will have to multiply it by the number of milliseconds in one day.

you can swipe the key and the value. For example

        String[] k = {"Elena", "Thomas", "Hamilton", "Suzie", "Phil"};
        int[] v = {341, 273, 278, 329, 445};
        TreeMap<Integer,String>a=new TreeMap();
        for (int i = 0; i < k.length; i++) 
           a.put(v[i],k[i]);            
        System.out.println(a.firstEntry().getValue()+"\t"+a.firstEntry().getKey());
        a.remove(a.firstEntry().getKey());
        System.out.println(a.firstEntry().getValue()+"\t"+a.firstEntry().getKey());

You need to pass the values of the dict into the Bike constructor before using like that. Or, see the namedtuple -- seems more in line with what you're trying to do.

You could do this:

String json = new ObjectMapper().writeValueAsString(yourObjectHere);

Any time you need to separate allocation from initialization, you'll need placement new and explicit calling of the destructor manually. Today, it's rarely necessary, since we have the standard containers, but if you have to implement some new sort of container, you'll need it.

You could use something like jQuery to "disable" this behaviour, though I hardly think it's a good solution as you get display logic in css & javascript. Still, depending upon your requirements you might find jQuery's css utils make life easier for you than trying hacky css, especially if you're trying to make it work for IE6

import sys
sys.stderr.write()

Is my choice, just more readable and saying exactly what you intend to do and portable across versions.

Edit: being 'pythonic' is a third thought to me over readability and performance... with these two things in mind, with python 80% of your code will be pythonic. list comprehension being the 'big thing' that isn't used as often (readability).

I have encountered this error on "an empty branch" on my local gitlab server. Some people mentioned that "you can not push for the first time on an empty branch". I tried to create a simple README file on the gitlab via my browser. Then everything fixed amazingly and the problem sorted out!! I mention that I was the master and the branch was not protected.

I took this question to mean how can you change the Default workspace so that when Eclipse boots up the workspace you want is automatically loaded:

• Go under preferences then type "workspace" in the search box provided to filter the list. Alternatively you can go to General>Startup and Shutdown>Workspaces.
• There you can set a flag to make Eclipse prompt you to select a workspace at startup by checking the "Prompt for workspace at startup" checkbox.
• You can set the number of previous workspaces to remember also. Finally there is a list of recent workspaces. If you just remove all but the one you want Eclipse will automatically startup with that workspace.

Downloading java dependencies is possible, if you actually really need to download them into a folder.

Example:

apply plugin: 'java'

dependencies {
  runtime group: 'com.netflix.exhibitor', name: 'exhibitor-standalone', version: '1.5.2'
  runtime group: 'org.apache.zookeeper',  name: 'zookeeper', version: '3.4.6'
}

repositories { mavenCentral() }

task getDeps(type: Copy) {
  from sourceSets.main.runtimeClasspath
  into 'runtime/'
}

Download the dependencies (and their dependencies) into the folder runtime when you execute gradle getDeps.

Adding skipLibCheck: true in compilerOptions inside tsconfig.json file fixed my issue.

"compilerOptions": {
   "skipLibCheck": true,
},

It depends on what you want to test:

• for a string, you can use If strName = vbNullString or IF strName = "" or Len(strName) = 0 (last one being supposedly faster)
• for an object, you can use If myObject is Nothing
• for a recordset field, you could use If isnull(rs!myField)
• for an Excel cell, you could use If range("B3") = "" or IsEmpty(myRange)

Extended discussion available here (for Access, but most of it works for Excel as well).

I struggled to get this working. That's why I'll add a complete solution here:

My objective is to add this header to the SOAP envelope:

   <soapenv:Header>
      <urn:OTAuthentication>
         <urn:AuthenticationToken>TOKEN</urn:AuthenticationToken>
      </urn:OTAuthentication>
   </soapenv:Header>

1. First create a SOAPHeaderHandler class.

   import java.util.Set;
   import java.util.TreeSet;
   
   import javax.xml.namespace.QName;
   import javax.xml.soap.SOAPElement;
   import javax.xml.soap.SOAPEnvelope;
   import javax.xml.soap.SOAPFactory;
   import javax.xml.soap.SOAPHeader;
   import javax.xml.ws.handler.MessageContext;
   import javax.xml.ws.handler.soap.SOAPHandler;
   import javax.xml.ws.handler.soap.SOAPMessageContext;
   
   public class SOAPHeaderHandler implements SOAPHandler<SOAPMessageContext> {
   
       private final String authenticatedToken;
   
       public SOAPHeaderHandler(String authenticatedToken) {
           this.authenticatedToken = authenticatedToken;
       }
   
       public boolean handleMessage(SOAPMessageContext context) {
           Boolean outboundProperty =
                   (Boolean) context.get(MessageContext.MESSAGE_OUTBOUND_PROPERTY);
           if (outboundProperty.booleanValue()) {
               try {
                   SOAPEnvelope envelope = context.getMessage().getSOAPPart().getEnvelope();
                   SOAPFactory factory = SOAPFactory.newInstance();
                   String prefix = "urn";
                   String uri = "urn:api.ecm.opentext.com";
                   SOAPElement securityElem =
                           factory.createElement("OTAuthentication", prefix, uri);
                   SOAPElement tokenElem =
                           factory.createElement("AuthenticationToken", prefix, uri);
                   tokenElem.addTextNode(authenticatedToken);
                   securityElem.addChildElement(tokenElem);
                   SOAPHeader header = envelope.addHeader();
                   header.addChildElement(securityElem);
               } catch (Exception e) {
                   e.printStackTrace();
               }
           } else {
               // inbound
           }
           return true;
       }
   
       public Set<QName> getHeaders() {
           return new TreeSet();
       }
   
       public boolean handleFault(SOAPMessageContext context) {
           return false;
       }
   
       public void close(MessageContext context) {
           //
       }
   }
   

   2. Add the handler to the proxy. Note that according javax.xml.ws.Binding's documentation: "If the returned chain is modified a call to setHandlerChain is required to configure the binding instance with the new chain."

   Authentication_Service authentication_Service = new Authentication_Service();
   
   Authentication basicHttpBindingAuthentication = authentication_Service.getBasicHttpBindingAuthentication();
   String authenticatedToken = "TOKEN";
   List<Handler> handlerChain = ((BindingProvider)basicHttpBindingAuthentication).getBinding().getHandlerChain();
   handlerChain.add(new SOAPHeaderHandler(authenticatedToken));
   ((BindingProvider)basicHttpBindingAuthentication).getBinding().setHandlerChain(handlerChain);
   

In response to comments on rexem's answer, with respect to whether a an inline view or CTE would be faster I recast the queries to use a table I, and everyone, had available: sys.objects.

WITH object_rows AS (
    SELECT object_id, 
        ROW_NUMBER() OVER ( ORDER BY object_id) RN
    FROM sys.objects)
SELECT object_id
FROM object_rows
WHERE RN > 1

SELECT object_id
FROM (SELECT object_id, 
        ROW_NUMBER() OVER ( ORDER BY object_id) RN
    FROM sys.objects) T
WHERE RN > 1

The query plans produced were exactly the same. I would expect in all cases, the query optimizer would come up with the same plan, at least in simple replacement of CTE with inline view or vice versa.

Of course, try your own queries on your own system to see if there is a difference.

Also, row_number() in the where clause is a common error in answers given on Stack Overflow. Logicaly row_number() is not available until the select clause is processed. People forget that and when they answer without testing the answer, the answer is sometimes wrong. (A charge I have myself been guilty of.)

You can think of O(log N) intuitively by saying the time is proportional to the number of digits in N.

If an operation performs constant time work on each digit or bit of an input, the whole operation will take time proportional to the number of digits or bits in the input, not the magnitude of the input; thus, O(log N) rather than O(N).

If an operation makes a series of constant time decisions each of which halves (reduces by a factor of 3, 4, 5..) the size of the input to be considered, the whole will take time proportional to log base 2 (base 3, base 4, base 5...) of the size N of the input, rather than being O(N).

And so on.

to fix this error either change the JSON to a JSON array (e.g. [1,2,3]) or change the
deserialized type so that it is a normal .NET type (e.g. not a primitive type like
integer, not a collection type like an array or List) that can be deserialized from a
JSON object.`

The whole message indicates that it is possible to serialize to a List object, but the input must be a JSON list. This means that your JSON must contain

"accounts" : [{<AccountObjectData}, {<AccountObjectData>}...],

Where AccountObject data is JSON representing your Account object or your Badge object

What it seems to be getting currently is

"accounts":{"github":"sergiotapia"}

Where accounts is a JSON object (denoted by curly braces), not an array of JSON objects (arrays are denoted by brackets), which is what you want. Try

"accounts" : [{"github":"sergiotapia"}]

It seems that none of the answers here will work with string-enums in strict-mode.

Consider enum as:

enum AnimalEnum {
  dog = "dog", cat = "cat", mouse = "mouse"
}

Accessing this with AnimalEnum["dog"] may result in an error like:

Element implicitly has an 'any' type because expression of type 'any' can't be used to index type 'typeof AnimalEnum'.ts(7053).

Proper solution for that case, write it as:

AnimalEnum["dog" as keyof typeof AnimalEnum]

These methods are efficient and good to start using a basic RecyclerView.

private List<YourItem> items;

public void setItems(List<YourItem> newItems)
{
    clearItems();
    addItems(newItems);
}

public void addItem(YourItem item, int position)
{
    if (position > items.size()) return;

    items.add(item);
    notifyItemInserted(position);
}

public void addMoreItems(List<YourItem> newItems)
{
    int position = items.size() + 1;
    newItems.addAll(newItems);
    notifyItemChanged(position, newItems);
}

public void addItems(List<YourItem> newItems)
{
    items.addAll(newItems);
    notifyDataSetChanged();
}

public void clearItems()
{
    items.clear();
    notifyDataSetChanged();
}

public void addLoader()
{
    items.add(null);
    notifyItemInserted(items.size() - 1);
}

public void removeLoader()
{
    items.remove(items.size() - 1);
    notifyItemRemoved(items.size());
}

public void removeItem(int position)
{
    if (position >= items.size()) return;

    items.remove(position);
    notifyItemRemoved(position);
}

public void swapItems(int positionA, int positionB)
{
    if (positionA > items.size()) return;
    if (positionB > items.size()) return;

    YourItem firstItem = items.get(positionA);

    videoList.set(positionA, items.get(positionB));
    videoList.set(positionB, firstItem);

    notifyDataSetChanged();
}

You can implement them inside of an Adapter Class or in your Fragment or Activity but in that case you have to instantiate the Adapter to call the notification methods. In my case I usually implement it in the Adapter.

I forgot that I had already an unused labs branch. Deleting it solved my problem:

git branch -d labs
git checkout -b labs/feature

Explanation:

Each name can only be a parent branch or a normal branch, not both. Thats why the branches labs and labs/feature can't exists both at the same time.

The reason: Branches are stored in the file system and there you also can't have a file labs and a directory labs at the same level.

If you are using SQL Express (which you are), then your login credentials are .\SQLEXPRESS

Here is the connectionString in the web config file which you can add:

<connectionStrings>
<add connectionString="Server=localhost\SQLEXPRESS;Database=yourDBName;Initial Catalog= yourDBName;Integrated Security=true" name="nametoCallBy" providerName="System.Data.SqlClient"/>
</connectionStrings>

Place is just above the system.web tag.

Then you can call it by:

connString = ConfigurationManager.ConnectionStrings["nametoCallBy"].ConnectionString;

As I said in a comment to aqingsao's answer, it doesn't quite work when the textarea has newline characters, at least on Windows.

I've change his answer slightly thus:

$(function() {
    $("textarea[maxlength]").bind('input propertychange', function() {
        var maxLength = $(this).attr('maxlength');
        //I'm guessing JavaScript is treating a newline as one character rather than two so when I try to insert a "max length" string into the database I get an error.
        //Detect how many newlines are in the textarea, then be sure to count them twice as part of the length of the input.
        var newlines = ($(this).val().match(/\n/g) || []).length
        if ($(this).val().length + newlines > maxLength) {
            $(this).val($(this).val().substring(0, maxLength - newlines));
        }
    })
});

Now when I try to paste a lot of data in with newlines, I get exactly the right number of characters.

Implement Login for Devices

Facebook Login for Devices is for devices that directly make HTTP calls over the internet. The following are the API calls and responses your device can make.

1. Enable Login for Devices

Change Settings > Advanced > OAuth Settings > Login from Devices to 'Yes'.

2. Generate a Code which is required for facebook device identification

When the person clicks Log in with Facebook, you device should make an HTTP POST to:

POST https://graph.facebook.com/oauth/device?
       type=device_code
       &amp;client_id=<YOUR_APP_ID>
       &amp;scope=<COMMA_SEPARATED_PERMISSION_NAMES> // e.g.public_profile,user_likes

The response comes in this form:

{
  "code": "92a2b2e351f2b0b3503b2de251132f47",
  "user_code": "A1NWZ9",
  "verification_uri": "https://www.facebook.com/device",
  "expires_in": 420,
  "interval": 5
}

This response means:

• Display the string “A1NWZ9” on your device
• Tell the person to go to “facebook.com/device” and enter this code
• The code expires in 420 seconds. You should cancel the login flow after that time if you do not receive an access token
• Your device should poll the Device Login API every 5 seconds to see if the authorization has been successful

3. Display the Code

Your device should display the user_code and tell people to visit the verification_uri such as facebook.com/device on their PC or smartphone. See the Design Guidelines.

4. Poll for Authorization

Your device should poll the Device Login API to see if the person successfully authorized your application. You should do this at the interval in the response to your call in Step 1, which is every 5 seconds. Your device should poll to:

POST https://graph.facebook.com/oauth/device?
       type=device_token
       &amp;client_id=<YOUR_APP_ID> 
       &amp;code=<LONG_CODE_FROM_STEP_1> //e.g."92a2b2e351f2b0b3503b2de251132f47"

You will get 200 HTTP code i.e User has successfully authorized the device. The device can now use the access_token value to make authenticated API calls.

5. Confirm Successful Login

Your device should display their name and if available, a profile picture until they click Continue. To get the person's name and profile picture, your device should make a standard Graph API call:

GET https://graph.facebook.com/v2.3/me?
      fields=name,picture&
      access_token=<USER_ACCESS_TOKEN>

Response:

{
  "name": "John Doe", 
  "picture": {
    "data": {
      "is_silhouette": false, 
      "url": "https://fbcdn.akamaihd.net/hmac...ile.jpg"
    }
  }, 
  "id": "2023462875238472"
}

6. Store Access Tokens

Your device should persist the access token to make other requests to the Graph API.

Device Login access tokens may be valid for up to 60 days but may be invalided in a number of scenarios. For example when a person changes their Facebook password their access token is invalidated.

If the token is invalid, your device should delete the token from its memory. The person using your device needs to perform the Device Login flow again from Step 1 to retrieve a new, valid token.

Just use .empty():

// snip...
}).done(function (data) {
    // Clear drop down list
    $(dropdown).empty(); // <<<<<< No more issue here
    // Fill drop down list with new data
    $(data).each(function () {
        // snip...

There's also a more concise way to build up the options:

// snip...
$(data).each(function () {
    $("<option />", {
        val: this.value,
        text: this.text
    }).appendTo(dropdown);
});

string currentDirectory = Path.GetDirectoryName(Assembly.GetEntryAssembly().Location);
string archiveFolder = Path.Combine(currentDirectory, "archive");
string[] files = Directory.GetFiles(archiveFolder, "*.zip");

The first parameter is the path. The second is the search pattern you want to use.

Here's another extension method:

    public static string Join(this IEnumerable<string> source, string separator)
    {
        return string.Join(separator, source);
    }

Yep, both and and or operators short-circuit -- see the docs.

As far as I can tell,

• hstore as it currently exists (in Postgresql 9.3) does not allow for nesting other objects and arrays as the values of its key/value pairs. however a future hstore patch will allow for nesting. this patch will not be in the 9.4 release and may not be included any time soon.

• json as it currently exists does allow for nesting, but is text-based, and does not allow for indexing, thus it is "slow"

• jsonb that will be released with 9.4 will have the current nesting capabilities of json, as well as the GIN/GIST indexing of hstore, so it will be fast

People working on postgresql 9.4 seem to be saying that the new, fast jsonb type will appeal to people who would have chosen to use a noSQL data store like MongoDB, but can now combine a relational database with query-able unstructured data under one roof

http://www.databasesoup.com/2014/02/why-hstore2jsonb-is-most-important.html

Benchmarks of postgresql 9.4 jsonb seem to be on par with or in some cases faster than MongoDB

You should be able to use forward slashes in Java to refer to file locations.

The BufferedReader class is used for wrapping other file readers whos read method may not be very efficient. A more detailed description can be found in the Java APIs.

Toolkit's use of BufferedReader is probably what you need.

Bad idea, don't do it ever - but here it is how it can be done:

int main()
{
   A aObj;
   int* ptr;

   ptr = (int*)&aObj;

   // MODIFY!
   *ptr = 100;
}

MongoVue is the best I found till now, it has great features like database or collection copy and text mode viewing for records which is extremely useful

if you have remote server installed on you machine. give server.py host as "localhost" and the port number. then client side , you have to give local ip- 127.0.0.1 and port number. then its works

If you have Matlab, you can open large CSV (or TXT) files via its import facility. The tool gives you various import format options including tables, column vectors, numeric matrix, etc. However, with Matlab being an interpreter package, it does take its own time to import such a large file and I was able to import one with more than 2 million rows in about 10 minutes.

The tool is accessible via Matlab's Home tab by clicking on the "Import Data" button. An example image of a large file upload is shown below: Once imported, the data appears on the right-hand-side Workspace, which can then be double-clicked in an Excel-like format and even be plotted in different formats.

I had a similar problem and this scale worked for me like a charm:

breaks = 10**(1:10)
scale_y_log10(breaks = breaks, labels = comma(breaks))

as you want the intermediate levels, too (10^3.5), you need to tweak the formatting:

breaks = 10**(1:10 * 0.5)
m <- ggplot(diamonds, aes(y = price, x = color)) + geom_boxplot()
m + scale_y_log10(breaks = breaks, labels = comma(breaks, digits = 1))

After executing::

1. Take a look at the echo client under http://code.google.com/p/pywebsocket/ It's a Google project.
2. A good search in github is: https://github.com/search?type=Everything&language=python&q=websocket&repo=&langOverride=&x=14&y=29&start_value=1 it returns clients and servers.
3. Bret Taylor also implemented web sockets over Tornado (Python). His blog post at: Web Sockets in Tornado and a client implementation API is shown at tornado.websocket in the client side support section.

Got it working. Here was my procedure:

1. Browse to the desired page
2. Open the dev console - F12 on Windows/Linux or option + ? + J on macOS
3. Select the Sources tab in chrome inspector
4. In the web browser window, hover over the desired element to initiate the popover
5. Hit F8 on Windows/Linux (or fn + F8 on macOS) while the popover is showing. If you have clicked anywhere on the actual page F8 will do nothing. Your last click needs to be somewhere in the inspector, like the sources tab
6. Go to the Elements tab in inspector
7. Find your popover (it will be nested in the trigger element's HTML)
8. Have fun modifying the CSS

Since a new question has just been closed against this: you shouldn't create Thread objects yourself. Here's another way to do it:

public void method() {
    Executors.newSingleThreadExecutor().submit(() -> {
        // yourCode
    });
}

You should probably retain the executor service between calls though.

Of course. That is normal and sane behaviour. Instead of closing and re-opening, you could rewind the file.

Like this :

String[] words = {"000", "aaa", "bbb", "ccc", "ddd"};
List<String> wordList = new ArrayList<String>(Arrays.asList(words));

or

List myList = new ArrayList();
String[] words = {"000", "aaa", "bbb", "ccc", "ddd"};
Collections.addAll(myList, words);

Only from code:

namespace xxx.DsXxxTableAdapters {_x000D_
    partial class ZzzTableAdapter_x000D_
    {_x000D_
        public void SetTimeout(int timeout)_x000D_
        {_x000D_
            if (this.Adapter.DeleteCommand != null) { this.Adapter.DeleteCommand.CommandTimeout = timeout; }_x000D_
            if (this.Adapter.InsertCommand != null) { this.Adapter.InsertCommand.CommandTimeout = timeout; }_x000D_
            if (this.Adapter.UpdateCommand != null) { this.Adapter.UpdateCommand.CommandTimeout = timeout; }_x000D_
            if (this._commandCollection == null) { this.InitCommandCollection(); }_x000D_
            if (this._commandCollection != null)_x000D_
            {_x000D_
                foreach (System.Data.SqlClient.SqlCommand item in this._commandCollection)_x000D_
                {_x000D_
                    if (item != null)_x000D_
                    { item.CommandTimeout = timeout; }_x000D_
                }_x000D_
            }_x000D_
        }_x000D_
    }_x000D_
 _x000D_
    //...._x000D_
 _x000D_
 }

iframe is the tag which you can use for call other html pages into your web page

<iframe src="http://www.google.co.in" name="targetframe" allowTransparency="true" scrolling="no" frameborder="0" >
    </iframe>

The === is not for checking string equalit , to do so you can use the Regxp functions for example

if (x.match(y) === null) {
// x and y are not equal 
}

there is also the test function

for UNIX time-stamp in milliseconds

moment().format('x') // lowerCase x

for UNIX time-stamp in seconds moment().format('X') // capital X

This answer taught me that you can set headers for an entire session:

s = requests.Session()
s.auth = ('user', 'pass')
s.headers.update({'x-test': 'true'})

# both 'x-test' and 'x-test2' are sent
s.get('http://httpbin.org/headers', headers={'x-test2': 'true'})

Bonus: Sessions also handle cookies.

A friendly method to use is the following, once prop updates it will automatically rerender component:

render {

let textWhenComponentUpdate = this.props.text 

return (
<View>
  <Text>{textWhenComponentUpdate}</Text>
</View>
)

}

I had the same error for a different package. My problem was that a dependent project was referencing a different version. I changed them to be the same version and all was good.

Complete walkthrough of writing setup.py scripts here. (with some examples)

If you'd like a real-world example, I could point you towards the setup.py scripts of a couple major projects. Django's is here, pyglet's is here. You can just browse the source of other projects for a file named setup.py for more examples.

These aren't simple examples; the tutorial link I gave has those. These are more complex, but also more practical.

I've gotten lots of information here so I wanted to post a solution I discovered.

The problem: Getting JSON data from Javascript on the browser, to the server, and having PHP successfully parse it.

Environment: Javascript in a browser (Firefox) on Windows. LAMP server as remote server: PHP 5.3.2 on Ubuntu.

What works (version 1):
1) JSON is just text. Text in a certain format, but just a text string.

2) In Javascript, var str_json = JSON.stringify(myObject) gives me the JSON string.

3) I use the AJAX XMLHttpRequest object in Javascript to send data to the server:

request= new XMLHttpRequest()
request.open("POST", "JSON_Handler.php", true)
request.setRequestHeader("Content-type", "application/json")
request.send(str_json)
[... code to display response ...]

4) On the server, PHP code to read the JSON string:

$str_json = file_get_contents('php://input');

This reads the raw POST data. $str_json now contains the exact JSON string from the browser.

What works (version 2):
1) If I want to use the "application/x-www-form-urlencoded" request header, I need to create a standard POST string of "x=y&a=b[etc]" so that when PHP gets it, it can put it in the $_POST associative array. So, in Javascript in the browser:

var str_json = "json_string=" + (JSON.stringify(myObject))

PHP will now be able to populate the $_POST array when I send str_json via AJAX/XMLHttpRequest as in version 1 above.

Displaying the contents of $_POST['json_string'] will display the JSON string. Using json_decode() on the $_POST array element with the json string will correctly decode that data and put it in an array/object.

The pitfall I ran into:
Initially, I tried to send the JSON string with the header of application/x-www-form-urlencoded and then tried to immediately read it out of the $_POST array in PHP. The $_POST array was always empty. That's because it is expecting data of the form yval=xval&[rinse_and_repeat]. It found no such data, only the JSON string, and it simply threw it away. I examined the request headers, and the POST data was being sent correctly.

Similarly, if I use the application/json header, I again cannot access the sent data via the $_POST array. If you want to use the application/json content-type header, then you must access the raw POST data in PHP, via php://input, not with $_POST.

References:
1) How to access POST data in PHP: How to access POST data in PHP?
2) Details on the application/json type, with some sample objects which can be converted to JSON strings and sent to the server: http://www.ietf.org/rfc/rfc4627.txt

Avoid raw types

Raw types refer to using a generic type without specifying a type parameter.

For example,

A list is a raw type, while List<String> is a parameterized type.

When generics were introduced in JDK 1.5, raw types were retained only to maintain backwards compatibility with older versions of Java. Although using raw types is still possible,

They should be avoided:

• They usually require casts
• They aren't type safe, and some important kinds of errors will only appear at runtime

On MacOS Mojave, I had this problem in Safari. The font-awesome images worked in Chrome but not in Safari, so I was sure it wasn't the site.

I got them to render by going to Preferences in the Safari menu, and disabling/unchecking "Prevent cross-site tracking" under the Privacy tab.

Not sure why this fixed it, but it did.

Add a reference to System.Management for your project, then try something like this:

namespace ConsoleApplication1
{
  using System;
  using System.Collections.Generic;
  using System.Management; // need to add System.Management to your project references.

  class Program
  {
    static void Main(string[] args)
    {
      var usbDevices = GetUSBDevices();

      foreach (var usbDevice in usbDevices)
      {
        Console.WriteLine("Device ID: {0}, PNP Device ID: {1}, Description: {2}",
            usbDevice.DeviceID, usbDevice.PnpDeviceID, usbDevice.Description);
      }

      Console.Read();
    }

    static List<USBDeviceInfo> GetUSBDevices()
    {
      List<USBDeviceInfo> devices = new List<USBDeviceInfo>();

      ManagementObjectCollection collection;
      using (var searcher = new ManagementObjectSearcher(@"Select * From Win32_USBHub"))
        collection = searcher.Get();      

      foreach (var device in collection)
      {
        devices.Add(new USBDeviceInfo(
        (string)device.GetPropertyValue("DeviceID"),
        (string)device.GetPropertyValue("PNPDeviceID"),
        (string)device.GetPropertyValue("Description")
        ));
      }

      collection.Dispose();
      return devices;
    }
  }

For me, I just updated to Xcode 8, and converted my Swift 2.2 code to Swift 3 code, and I got errors in the Unit Testing and UI Testing. I just cleaned and then all the errors disappeared.

From ScottGu's blog:

Starting with the ASP.NET MVC 3 Beta release, you can now add a file called _ViewStart.cshtml (or _ViewStart.vbhtml for VB) underneath the \Views folder of your project:

The _ViewStart file can be used to define common view code that you want to execute at the start of each View’s rendering. For example, we could write code within our _ViewStart.cshtml file to programmatically set the Layout property for each View to be the SiteLayout.cshtml file by default:

Because this code executes at the start of each View, we no longer need to explicitly set the Layout in any of our individual view files (except if we wanted to override the default value above).

Important: Because the _ViewStart.cshtml allows us to write code, we can optionally make our Layout selection logic richer than just a basic property set. For example: we could vary the Layout template that we use depending on what type of device is accessing the site – and have a phone or tablet optimized layout for those devices, and a desktop optimized layout for PCs/Laptops. Or if we were building a CMS system or common shared app that is used across multiple customers we could select different layouts to use depending on the customer (or their role) when accessing the site.

This enables a lot of UI flexibility. It also allows you to more easily write view logic once, and avoid repeating it in multiple places.

Also see this.

In a more general sense this ability of MVC framework to "know" about _Viewstart.cshtml is called "Coding by convention".

Convention over configuration (also known as coding by convention) is a software design paradigm which seeks to decrease the number of decisions that developers need to make, gaining simplicity, but not necessarily losing flexibility. The phrase essentially means a developer only needs to specify unconventional aspects of the application. For example, if there's a class Sale in the model, the corresponding table in the database is called “sales” by default. It is only if one deviates from this convention, such as calling the table “products_sold”, that one needs to write code regarding these names.

Wikipedia

There's no magic to it. Its just been written into the core codebase of the MVC framework and is therefore something that MVC "knows" about. That why you don't find it in the .config files or elsewhere; it's actually in the MVC code. You can however override to alter or null out these conventions.

as in javascript:

mydata.match(/'([^']+)'/)[1]

the actual regexp is: /'([^']+)'/

if you use the non greedy modifier (as per another post) it's like this:

mydata.match(/'(.*?)'/)[1]

it is cleaner.

You can use HTML5 Fullscreen API for this (which is the most suitable way i think).

The fullscreen has to be triggered via a user event (click, keypress) otherwise it won't work.

Here is a button which makes the div fullscreen on click. And in fullscreen mode, the button click will exit fullscreen mode.

$('#toggle_fullscreen').on('click', function(){_x000D_
  // if already full screen; exit_x000D_
  // else go fullscreen_x000D_
  if (_x000D_
    document.fullscreenElement ||_x000D_
    document.webkitFullscreenElement ||_x000D_
    document.mozFullScreenElement ||_x000D_
    document.msFullscreenElement_x000D_
  ) {_x000D_
    if (document.exitFullscreen) {_x000D_
      document.exitFullscreen();_x000D_
    } else if (document.mozCancelFullScreen) {_x000D_
      document.mozCancelFullScreen();_x000D_
    } else if (document.webkitExitFullscreen) {_x000D_
      document.webkitExitFullscreen();_x000D_
    } else if (document.msExitFullscreen) {_x000D_
      document.msExitFullscreen();_x000D_
    }_x000D_
  } else {_x000D_
    element = $('#container').get(0);_x000D_
    if (element.requestFullscreen) {_x000D_
      element.requestFullscreen();_x000D_
    } else if (element.mozRequestFullScreen) {_x000D_
      element.mozRequestFullScreen();_x000D_
    } else if (element.webkitRequestFullscreen) {_x000D_
      element.webkitRequestFullscreen(Element.ALLOW_KEYBOARD_INPUT);_x000D_
    } else if (element.msRequestFullscreen) {_x000D_
      element.msRequestFullscreen();_x000D_
    }_x000D_
  }_x000D_
});

#container{_x000D_
  border:1px solid red;_x000D_
  border-radius: .5em;_x000D_
  padding:10px;_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<div id="container">_x000D_
  <p>_x000D_
    <a href="#" id="toggle_fullscreen">Toggle Fullscreen</a>_x000D_
  </p>_x000D_
  I will be fullscreen, yay!_x000D_
</div>

Please also note that Fullscreen API for Chrome does not work in non-secure pages. See https://sites.google.com/a/chromium.org/dev/Home/chromium-security/deprecating-powerful-features-on-insecure-origins for more details.

Another thing to note is the :fullscreen CSS selector. You can append this to any css selector so the that the rules will be applied when that element is fullscreen:

#container:-webkit-full-screen,
#container:-moz-full-screen,
#container:-ms-fullscreen,
#container:fullscreen {
    width: 100vw;
    height: 100vh;
    }

if you have added a new line, Make sure you have added next line syntax in previous line. typically if "\" is missing in your previous line of changes, you will get this error.

git branch --set-upstream <<origin/branch>> is officially not supported anymore and is replaced by git branch --set-upstream-to <<origin/branch>>

It is surprising the question of validating an email address continually comes up on SO!

You can find one often-mentioned practical solution here: How to Find or Validate an Email Address.

Excerpt:

The virtue of my regular expression above is that it matches 99% of the email addresses in use today. All the email address it matches can be handled by 99% of all email software out there. If you're looking for a quick solution, you only need to read the next paragraph. If you want to know all the trade-offs and get plenty of alternatives to choose from, read on.

See this answer on SO for a discussion of the merits of the article at the above link. In particular, the comment dated 2012-04-17 reads:

To all the complainers: after 3 hours experimenting all the solutions offered in this gigantic discussion, this is THE ONLY good java regex solution I can find. None of the rfc5322 stuff works on java regex.

I've created a factory that controls shared scope between route path's pattern, so you can maintain the shared data just when users are navigating in the same route parent path.

.controller('CadastroController', ['$scope', 'RouteSharedScope',
    function($scope, routeSharedScope) {
      var customerScope = routeSharedScope.scopeFor('/Customer');
      //var indexScope = routeSharedScope.scopeFor('/');
    }
 ])

So, if the user goes to another route path, for example '/Support', the shared data for path '/Customer' will be automatically destroyed. But, if instead of this the user goes to 'child' paths, like '/Customer/1' or '/Customer/list' the the scope won't be destroyed.

The current version (2019/03/07) is Build Tools for Visual Studio 2017. It's an online installer, you need to include at least the individual components:

• VC++ 2017 version xx.x tools
• Windows SDK to use standard libraries.

When you implement the action in the controller, use

return View("Index");

or

return RedirectToAction("Index");

where Index.cshtml (or the page that generates the action) page is already defined. Otherwise you are likely encountering "the view or its master was not found..." error.

To solve this without jQuery .each() you'd have to fix your code like this:

var listItems = $("#productList").find("li");
var ind, len, product;

for ( ind = 0, len = listItems.length; ind < len; ind++ ) {
    product = $(listItems[ind]);

    // ...
}

Bugs in your original code:

1. for ... in will also loop through all inherited properties; i.e. you will also get a list of all functions that are defined by jQuery.

2. The loop variable li is not the list item, but the index to the list item. In that case the index is a normal array index (i.e. an integer)

Basically you are save to use .each() as it is more comfortable, but espacially when you are looping bigger arrays the code in this answer will be much faster.

For other alternatives to .each() you can check out this performance comparison: http://jsperf.com/browser-diet-jquery-each-vs-for-loop

Following answer may help you

perform your date ordering by your date identifier but use to_char() function in select clause and use some other identifier in select clause for date

e.g.

SELECT TO_CHAR(DISPDATE1,'DD/MM/YYYY') AS DISPDATE,
SUM(APPLCOUNT) AS APPLIED,
SUM(CONFCOUNT) AS CONFIRMED
FROM
    (
        SELECT COUNT(ID) AS APPLCOUNT,
                   0 AS CONFCOUNT,
                   STUDENT.APPLIED_ON AS DISPDATE1
            FROM STUDENT
            WHERE STUDENT.ID = P_ID
            GROUP BY STUDENT.APPLIED_ON
        UNION
            SELECT 0 AS APPLCOUNT,
                   COUNT(ID) AS CONFCOUNT,
                   STUDENT.CONFIRMED_ON AS DISPDATE1
            FROM STUDENT
            WHERE STUDENT.ID = P_ID
            GROUP BY STUDENT.CONFIRMED_ON
    )
GROUP BY DISPDATE1
ORDER BY DISPDATE1;

Common issue

Naively type casting any string into an integer like so

SELECT ''::integer

Often results to the famous error:

Query failed: ERROR: invalid input syntax for integer: ""

Problem

PostgreSQL has no pre-defined function for safely type casting any string into an integer.

Solution

Create a user-defined function inspired by PHP's intval() function.

CREATE FUNCTION intval(character varying) RETURNS integer AS $$

SELECT
CASE
    WHEN length(btrim(regexp_replace($1, '[^0-9]', '','g')))>0 THEN btrim(regexp_replace($1, '[^0-9]', '','g'))::integer
    ELSE 0
END AS intval;

$$
LANGUAGE SQL
IMMUTABLE
RETURNS NULL ON NULL INPUT;

Usage

/* Example 1 */
SELECT intval('9000');
-- output: 9000

/* Example 2 */
SELECT intval('9gag');
-- output: 9

/* Example 3 */
SELECT intval('the quick brown fox jumps over the lazy dog');
-- output: 0

You can go to your /var/lib/pgsql/data/pg_hba.conf file and add trust in place of Ident It worked for me.

It's an unportable way to remove all data from the input buffer till the next newline. I've seen it used in cases like that:

char c;
char s[32];
puts("Type a char");
c=getchar();
fflush(stdin);
puts("Type a string");
fgets(s,32,stdin);

Without the fflush(), if you type a character, say "a", and the hit enter, the input buffer contains "a\n", the getchar() peeks the "a", but the "\n" remains in the buffer, so the next fgets() will find it and return an empty string without even waiting for user input.

However, note that this use of fflush() is unportable. I've tested right now on a Linux machine, and it does not work, for example.

For reading a xlsx file we can use Apache POI libs Try this:

public static void readXLSXFile() throws IOException
    {
        InputStream ExcelFileToRead = new FileInputStream("C:/Test.xlsx");
        XSSFWorkbook  wb = new XSSFWorkbook(ExcelFileToRead);

        XSSFWorkbook test = new XSSFWorkbook(); 

        XSSFSheet sheet = wb.getSheetAt(0);
        XSSFRow row; 
        XSSFCell cell;

        Iterator rows = sheet.rowIterator();

        while (rows.hasNext())
        {
            row=(XSSFRow) rows.next();
            Iterator cells = row.cellIterator();
            while (cells.hasNext())
            {
                cell=(XSSFCell) cells.next();

                if (cell.getCellType() == XSSFCell.CELL_TYPE_STRING)
                {
                    System.out.print(cell.getStringCellValue()+" ");
                }
                else if(cell.getCellType() == XSSFCell.CELL_TYPE_NUMERIC)
                {
                    System.out.print(cell.getNumericCellValue()+" ");
                }
                else
                {
                    //U Can Handel Boolean, Formula, Errors
                }
            }
            System.out.println();
        }

    }

Maybe it's a little too late, but I also wanted the same behavior before. And the solution I went with works quite well in one of the apps currently on the App Store. Since I haven't seen anyone goes with similar method, I would like to share it here. The downside of this solution is that it requires subclassing UINavigationController. Though using Method Swizzling might help avoiding that, I didn't go that far.

So, the default back button is actually managed by UINavigationBar. When a user taps on the back button, UINavigationBar ask its delegate if it should pop the top UINavigationItem by calling navigationBar(_:shouldPop:). UINavigationController actually implement this, but it doesn't publicly declare that it adopts UINavigationBarDelegate (why!?). To intercept this event, create a subclass of UINavigationController, declare its conformance to UINavigationBarDelegate and implement navigationBar(_:shouldPop:). Return true if the top item should be popped. Return false if it should stay.

There are two problems. The first is that you must call the UINavigationController version of navigationBar(_:shouldPop:) at some point. But UINavigationBarController doesn't publicly declare it conformance to UINavigationBarDelegate, trying to call it will result in a compile time error. The solution I went with is to use Objective-C runtime to get the implementation directly and call it. Please let me know if anyone has a better solution.

The other problem is that navigationBar(_:shouldPop:) is called first follows by popViewController(animated:) if the user taps on the back button. The order reverses if the view controller is popped by calling popViewController(animated:). In this case, I use a boolean to detect if popViewController(animated:) is called before navigationBar(_:shouldPop:) which mean that the user has tapped on the back button.

Also, I make an extension of UIViewController to let the navigation controller ask the view controller if it should be popped if the user taps on the back button. View controllers can return false and do any necessary actions and call popViewController(animated:) later.

class InterceptableNavigationController: UINavigationController, UINavigationBarDelegate {
    // If a view controller is popped by tapping on the back button, `navigationBar(_:, shouldPop:)` is called first follows by `popViewController(animated:)`.
    // If it is popped by calling to `popViewController(animated:)`, the order reverses and we need this flag to check that.
    private var didCallPopViewController = false

    override func popViewController(animated: Bool) -> UIViewController? {
        didCallPopViewController = true
        return super.popViewController(animated: animated)
    }

    func navigationBar(_ navigationBar: UINavigationBar, shouldPop item: UINavigationItem) -> Bool {
        // If this is a subsequence call after `popViewController(animated:)`, we should just pop the view controller right away.
        if didCallPopViewController {
            return originalImplementationOfNavigationBar(navigationBar, shouldPop: item)
        }

        // The following code is called only when the user taps on the back button.

        guard let vc = topViewController, item == vc.navigationItem else {
            return false
        }

        if vc.shouldBePopped(self) {
            return originalImplementationOfNavigationBar(navigationBar, shouldPop: item)
        } else {
            return false
        }
    }

    func navigationBar(_ navigationBar: UINavigationBar, didPop item: UINavigationItem) {
        didCallPopViewController = false
    }

    /// Since `UINavigationController` doesn't publicly declare its conformance to `UINavigationBarDelegate`,
    /// trying to called `navigationBar(_:shouldPop:)` will result in a compile error.
    /// So, we'll have to use Objective-C runtime to directly get super's implementation of `navigationBar(_:shouldPop:)` and call it.
    private func originalImplementationOfNavigationBar(_ navigationBar: UINavigationBar, shouldPop item: UINavigationItem) -> Bool {
        let sel = #selector(UINavigationBarDelegate.navigationBar(_:shouldPop:))
        let imp = class_getMethodImplementation(class_getSuperclass(InterceptableNavigationController.self), sel)
        typealias ShouldPopFunction = @convention(c) (AnyObject, Selector, UINavigationBar, UINavigationItem) -> Bool
        let shouldPop = unsafeBitCast(imp, to: ShouldPopFunction.self)
        return shouldPop(self, sel, navigationBar, item)
    }
}

extension UIViewController {
    @objc func shouldBePopped(_ navigationController: UINavigationController) -> Bool {
        return true
    }
}

And in you view controllers, implement shouldBePopped(_:). If you don't implement this method, the default behavior will be to pop the view controller as soon as the user taps on the back button just like normal.

class MyViewController: UIViewController {
    override func shouldBePopped(_ navigationController: UINavigationController) -> Bool {
        let alert = UIAlertController(title: "Do you want to go back?",
                                      message: "Do you really want to go back? Tap on \"Yes\" to go back. Tap on \"No\" to stay on this screen.",
                                      preferredStyle: .alert)
        alert.addAction(UIAlertAction(title: "No", style: .cancel, handler: nil))
        alert.addAction(UIAlertAction(title: "Yes", style: .default, handler: { _ in
            navigationController.popViewController(animated: true)
        }))
        present(alert, animated: true, completion: nil)
        return false
    }
}

Using JACOB call Office Word is a 100% perfect solution. But it only supports on Windows platform because need Office Word installed.

1. Download JACOB archive (the latest version is 1.19);
2. Add jacob.jar to your project classpath;
3. Add jacob-1.19-x32.dll or jacob-1.19-x64.dll (depends on your jdk version) to ...\Java\jdk1.x.x_xxx\jre\bin

4. Using JACOB API call Office Word to convert doc/docx to pdf.

   public void convertDocx2pdf(String docxFilePath) {
   File docxFile = new File(docxFilePath);
   String pdfFile = docxFilePath.substring(0, docxFilePath.lastIndexOf(".docx")) + ".pdf";
   
   if (docxFile.exists()) {
       if (!docxFile.isDirectory()) { 
           ActiveXComponent app = null;
   
           long start = System.currentTimeMillis();
           try {
               ComThread.InitMTA(true); 
               app = new ActiveXComponent("Word.Application");
               Dispatch documents = app.getProperty("Documents").toDispatch();
               Dispatch document = Dispatch.call(documents, "Open", docxFilePath, false, true).toDispatch();
               File target = new File(pdfFile);
               if (target.exists()) {
                   target.delete();
               }
               Dispatch.call(document, "SaveAs", pdfFile, 17);
               Dispatch.call(document, "Close", false);
               long end = System.currentTimeMillis();
               logger.info("============Convert Finished:" + (end - start) + "ms");
           } catch (Exception e) {
               logger.error(e.getLocalizedMessage(), e);
               throw new RuntimeException("pdf convert failed.");
           } finally {
               if (app != null) {
                   app.invoke("Quit", new Variant[] {});
               }
               ComThread.Release();
           }
       }
   }
   

   }

0, 1, 2...9 are file descriptors in bash.

0 stands for stdin, 1 stands for stdout, 2 stands for stderror. 3~9 is spare for any other temporary usage.

Any file descriptor can be redirected to other file descriptor or file by using operator > or >>(append).

Usage: <file_descriptor> > <filename | &file_descriptor>

Please reference to http://www.tldp.org/LDP/abs/html/io-redirection.html

You can do this in Python using simple function:

def get_cosine(text1, text2):
  vec1 = text1
  vec2 = text2
  intersection = set(vec1.keys()) & set(vec2.keys())
  numerator = sum([vec1[x] * vec2[x] for x in intersection])
  sum1 = sum([vec1[x]**2 for x in vec1.keys()])
  sum2 = sum([vec2[x]**2 for x in vec2.keys()])
  denominator = math.sqrt(sum1) * math.sqrt(sum2)
  if not denominator:
     return 0.0
  else:
     return round(float(numerator) / denominator, 3)
dataSet1 = [3, 45, 7, 2]
dataSet2 = [2, 54, 13, 15]
get_cosine(dataSet1, dataSet2)

Use the continue keyword. Read here.

The continue statement skips the current iteration of a for, while , or do-while loop.

copy your Dataframe column and simply apply

df=data['x']
newdf=df.str.lower()

Me, I'd do it something like this:

HTML:

onclick="myfunction({path:'/myController/myAction', ok:myfunctionOnOk, okArgs:['/myController2/myAction2','myParameter2'], cancel:myfunctionOnCancel, cancelArgs:['/myController3/myAction3','myParameter3']);"

JS:

function myfunction(params)
{
  var path = params.path;

  /* do stuff */

  // on ok condition 
  params.ok(params.okArgs);

  // on cancel condition
  params.cancel(params.cancelArgs);  
}

But then I'd also probable be binding a closure to a custom subscribed event. You need to add some detail to the question really, but being first-class functions are easily passable and getting params to them can be done any number of ways. I would avoid passing them as string labels though, the indirection is error prone.

For Laravel 5 :

$items = Items::lists('name', 'id');

Push an item onto the beginning of the collection.

$items->prepend($value, $key = null);

SQLLite requires dates to be in YYYY-MM-DD format. Since the data in your database and the string in your query isn't in that format, it is probably treating your "dates" as strings.

It's not a direct answer on question (its not about Actions), but it also allow you to scroll easily to required element:

element = driver.find_element_by_id('some_id')
element.location_once_scrolled_into_view

This actually intend to return you coordinates (x, y) of element on page, but also scroll down right to target element

I have MySQL schema with autogen values. I use strategy=GenerationType.IDENTITY tag and seems to work fine in MySQL I guess it should work most db engines as well.

CREATE TABLE user (
    id bigint NOT NULL auto_increment,
    name varchar(64) NOT NULL default '',
    PRIMARY KEY (id)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

User.java:

// mark this JavaBean to be JPA scoped class
@Entity
@Table(name="user")
public class User {
    @Id @GeneratedValue(strategy=GenerationType.IDENTITY)
    private long id;    // primary key (autogen surrogate)

    @Column(name="name")
    private String name;

    public long getId() { return id; }
    public void setId(long id) { this.id = id; }

    public String getName() { return name; }
    public void setName(String name) { this.name=name; }
}

You can also use "shouldReceiveTouch" method of UIGestureRecognizer

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:     (UITouch *)touch {
     UIView *view = touch.view; 
     NSLog(@"%d", view.tag); 
}    

Dont forget to set delegate of your gesture recognizer.

try

pip3 install --user --upgrade pandas

You can listen resize event and fire where some dimension change

directive

(function() {
'use strict';

    angular
    .module('myApp.directives')
    .directive('resize', ['$window', function ($window) {
        return {
            link: link,
            restrict: 'A'
        };

        function link(scope, element, attrs){
            scope.width = $window.innerWidth;
            function onResize(){
                // uncomment for only fire when $window.innerWidth change   
                // if (scope.width !== $window.innerWidth)
                {
                    scope.width = $window.innerWidth;
                    scope.$digest();
                }
            };

            function cleanUp() {
                angular.element($window).off('resize', onResize);
            }

            angular.element($window).on('resize', onResize);
            scope.$on('$destroy', cleanUp);
        }
    }]);
})();

In html

<div class="row" resize> ,
    <div class="col-sm-2 col-xs-6" ng-repeat="v in tag.vod"> 
        <h4 ng-bind="::v.known_as"></h4>
    </div> 
</div> 

Controller :

$scope.$watch('width', function(old, newv){
     console.log(old, newv);
 })

Try using the success() call back

$http.get('/Documents/DocumentsList/' + caseId).success(function (result) {
    $scope.Documents = result;
});

But now since Documents is an array and not a promise, remove the ()

<li ng-repeat="document in Documents" ng-class="IsFiltered(document.Filtered)"> <span>
           <input type="checkbox" name="docChecked" id="doc_{{document.Id}}" ng-model="document.Filtered" />
        </span>
 <span>{{document.Name}}</span>

</li>

It's a little tricky because of the nested IFs but here is my answer (confirmed in Google Spreadsheets):

=IF(AND(A2>=0,    A2<500),  "Less than 500", 
 IF(AND(A2>=500,  A2<1000), "Between 500 and 1000", 
 IF(AND(A2>=1000, A2<1500), "Between 1000 and 1500", 
 IF(AND(A2>=1500, A2<2000), "Between 1500 and 2000", "Undefined"))))

The new tests you wrote (directly or indirectly) use classes that log using Log4j.

Log4J needs to be configured for this logging to work properly.

Put a log4j.properties (or log4j.xml) file in the root of your test classpath.

It should have some basic configuration such as

# Set root logger level to DEBUG and its only appender to A1.
log4j.rootLogger=DEBUG, A1

# A1 is set to be a ConsoleAppender.
log4j.appender.A1=org.apache.log4j.ConsoleAppender

# A1 uses PatternLayout.
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
log4j.appender.A1.layout.ConversionPattern=%-4r [%t] %-5p %c %x - %m%n

# An alternative logging format:
# log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1} - %m%n

An appender outputs to the console by default, but you can also explicitly set the target like this:

log4j.appender.A1.Target=System.out

This will redirect all output in a nice format to the console. More info can be found here in the Log4J manual,

Log4J Logging will then be properly configured and this warning will disappear.

Actually I don't like the GOTO command too, but it's in official Microsoft materials, and here are all allowed syntaxes.

If the end point of the statement list of a switch section is reachable, a compile-time error occurs. This is known as the "no fall through" rule. The example

switch (i) {
case 0:
   CaseZero();
   break;
case 1:
   CaseOne();
   break;
default:
   CaseOthers();
   break;
}

is valid because no switch section has a reachable end point. Unlike C and C++, execution of a switch section is not permitted to "fall through" to the next switch section, and the example

switch (i) {
case 0:
   CaseZero();
case 1:
   CaseZeroOrOne();
default:
   CaseAny();
}

results in a compile-time error. When execution of a switch section is to be followed by execution of another switch section, an explicit goto case or goto default statement must be used:

switch (i) {
case 0:
   CaseZero();
   goto case 1;
case 1:
   CaseZeroOrOne();
   goto default;
default:
   CaseAny();
   break;
}

Multiple labels are permitted in a switch-section. The example

switch (i) {
case 0:
   CaseZero();
   break;
case 1:
   CaseOne();
   break;
case 2:
default:
   CaseTwo();
   break;
}

I believe in this particular case, the GOTO can be used, and it's actually the only way to fallthrough.

Since I'm using Bootstrap 3, I use a directive: (see plunkr)

    var ValidSubmit = ['$parse', function ($parse) {
        return {
            compile: function compile(tElement, tAttrs, transclude) {
                return {
                    post: function postLink(scope, element, iAttrs, controller) {
                        var form = element.controller('form');
                        form.$submitted = false;
                        var fn = $parse(iAttrs.validSubmit);
                        element.on('submit', function(event) {
                            scope.$apply(function() {
                                element.addClass('ng-submitted');
                                form.$submitted = true;
                                if(form.$valid) {
                                    fn(scope, {$event:event});
                                }
                            });
                        });
                        scope.$watch(function() { return form.$valid}, function(isValid) {
                            if(form.$submitted == false) return;
                            if(isValid) {
                                element.removeClass('has-error').addClass('has-success');
                            } else {
                                element.removeClass('has-success');
                                element.addClass('has-error');
                            }
                        });
                    }
                }
            }
        }
    }]

    app.directive('validSubmit', ValidSubmit);

and then in my HTML:

<form class="form-horizontal" role="form" name="form" novalidate valid-submit="connect()">
  <div class="form-group">
    <div class="input-group col col-sm-11 col-sm-offset-1">
      <span class="input-group-addon input-large"><i class="glyphicon glyphicon-envelope"></i></span>
      <input class="input-large form-control" type="email" id="email" placeholder="Email" name="email" ng-model="email" required="required">
    </div>
    <p class="col-sm-offset-3 help-block error" ng-show="form.$submitted && form.email.$error.required">please enter your email</p>
    <p class="col-sm-offset-3 help-block error" ng-show="form.$submitted && form.email.$error.email">please enter a valid email</p>
  </div>
</form>

UPDATED

In my latest project, I use Ionic so I have the following, which automatically puts .valid or .invalid on the input-item's:

.directive('input', ['$timeout', function ($timeout) {
  function findParent(element, selector) {
    selector = selector || 'item';
    var parent = element.parent();
    while (parent && parent.length) {
      parent = angular.element(parent);
      if (parent.hasClass(selector)) {
        break;
      }
      parent = parent && parent.parent && parent.parent();
    }
    return parent;
  }

  return {
    restrict: 'E',
    require: ['?^ngModel', '^form'],
    priority: 1,
    link: function (scope, element, attrs, ctrls) {
      var ngModelCtrl = ctrls[0];
      var form = ctrls[1];

      if (!ngModelCtrl || form.$name !== 'form' || attrs.type === 'radio' || attrs.type === 'checkbox') {
        return;
      }

      function setValidClass() {
        var parent = findParent(element);
        if (parent && parent.toggleClass) {
          parent.addClass('validated');
          parent.toggleClass('valid', ngModelCtrl.$valid && (ngModelCtrl.$dirty || form.$submitted));
          parent.toggleClass('invalid', ngModelCtrl.$invalid && (ngModelCtrl.$dirty || form.$submitted));
          $timeout(angular.noop);
        }
      }

      scope.$watch(function () {
        return form.$submitted;
      }, function (b, a) {
        setValidClass();
      });


      var before = void 0;
      var update = function () {
        before = element.val().trim();
        ngModelCtrl.$setViewValue(before);
        ngModelCtrl.$render();
        setValidClass();
      };
      element
        .on('focus', function (e) {
          if (ngModelCtrl.$pristine) {
            element.removeClass('$blurred');
          }

        })
        .on('blur', function (e) {
          if (ngModelCtrl.$dirty) {
            setValidClass();
            element.addClass('$blurred');
          }
        }).on('change', function (e) {
          if (form.$submitted || element.hasClass('$blurred')) {
            setValidClass();
          }
        }).on('paste', function (e) {
          if (form.$submitted || element.hasClass('$blurred')) {
            setValidClass();
          }
        })
      ;

    }
  };
}])

and then in the HTML:

    <form name='form' novalidate="novalidate" ng-submit="auth.signin(form, vm)">
          <label class="item item-input item-floating-label">
            <span class="input-label">Email</span>
            <input type="email" placeholder="Email" ng-model="vm.email" autofocus="true" required
              >
          </label>
          <button ng-if="!posting" type="submit" class="item button-block item-balanced item-icon-right  call-to-action">Login<i class="icon ion-chevron-right"></i>
          </button>

and in the controller:

  self.signin = function (form, data) {
    if (!form.$valid) return;

    Authentication.emailLogin(data)
    //...

so, now, in the CSS, you can do stuff like:

.item.valid::before{
    float: right;
    font-family: "Ionicons";
    font-style: normal;
    font-weight: normal;
    font-variant: normal;
    text-transform: none;
    text-rendering: auto;
    line-height: 1;
    -webkit-font-smoothing: antialiased;
    -moz-osx-font-smoothing: grayscale;
    color: #66cc33;
    margin-right: 8px;
    font-size: 24px;
    content: "\f122";
}

.item.invalid::before{
    float: right;
    font-family: "Ionicons";
    font-style: normal;
    font-weight: normal;
    font-variant: normal;
    text-transform: none;
    text-rendering: auto;
    line-height: 1;
    -webkit-font-smoothing: antialiased;
    -moz-osx-font-smoothing: grayscale;
    color: #ef4e3a;
    margin-right: 8px;
    font-size: 24px;
    content: "\f12a";

/*
    border-left: solid 2px #ef4e3a !important;
    border-right: solid 2px #ef4e3a !important;
*/
}

MUCH SIMPLER!

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

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

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

Hope that helps.

I suppose that you needed that in form of a script, but if someone else just want to have a look through the Jenkins GUI, that list can be found by selecting the "Environment Variables" section in contextual left menu of every build Select project => Select build => Environment Variables

You can also try:

INSERT IGNORE
  INTO table_1 
SELECT *
  FROM table_2
     ;

which allows those rows in table_1 to supersede those in table_2 that have a matching primary key, while still inserting rows with new primary keys.

Alternatively,

REPLACE
   INTO table_1
 SELECT *
   FROM table_2
      ;

will update those rows already in table_1 with the corresponding row from table_2, while inserting rows with new primary keys.

Convert the string to an integer base 16 then to hexadecimal.

print hex(int(string, base=16))

These are built-in functions.

http://docs.python.org/2/library/functions.html#int

Example

>>> string = 'AA'
>>> _int = int(string, base=16)
>>> _hex = hex(_int)
>>> print _int
170
>>> print _hex
0xaa
>>> 

If your XSLT processor supports EXSLT, you can use str:tokenize, otherwise, the link contains an implementation using functions like substring-before.

I use something like this:

if schema_id('newSchema') is null
    exec('create schema newSchema');

The advantage is if you have this code in a long sql-script you can always execute it with the other code, and its short.

you can also override ToString() if your list item have more than one string

public class ListItem
{

    public string string1 { get; set; }

    public string string2 { get; set; }

    public string string3 { get; set; }

    public override string ToString()
    {
        return string.Join(
        ","
        , string1 
        , string2 
        , string3);

    }

}

to get csv string:

ListItem item = new ListItem();
item.string1 = "string1";
item.string2 = "string2";
item.string3 = "string3";

List<ListItem> list = new List<ListItem>();
list.Add(item);

string strinCSV = (string.Join("\n", list.Select(x => x.ToString()).ToArray()));

In case of MySQL or SQLite the correct keyword is IFNULL (not ISNULL).

 SELECT iar.Description, 
      IFNULL(iai.Quantity,0) as Quantity, 
      IFNULL(iai.Quantity * rpl.RegularPrice,0) as 'Retail', 
      iar.Compliance 
    FROM InventoryAdjustmentReason iar
    LEFT OUTER JOIN InventoryAdjustmentItem iai  on (iar.Id = iai.InventoryAdjustmentReasonId)
    LEFT OUTER JOIN Item i on (i.Id = iai.ItemId)
    LEFT OUTER JOIN ReportPriceLookup rpl on (rpl.SkuNumber = i.SkuNo)
WHERE iar.StoreUse = 'yes'

Regarding storing credentials, I use two functions(that are normally in a module that is loaded from my profile):

#=====================================================================
# Get-MyCredential
#=====================================================================
function Get-MyCredential
{
param(
$CredPath,
[switch]$Help
)
$HelpText = @"

    Get-MyCredential
    Usage:
    Get-MyCredential -CredPath `$CredPath

    If a credential is stored in $CredPath, it will be used.
    If no credential is found, Export-Credential will start and offer to
    Store a credential at the location specified.

"@
    if($Help -or (!($CredPath))){write-host $Helptext; Break}
    if (!(Test-Path -Path $CredPath -PathType Leaf)) {
        Export-Credential (Get-Credential) $CredPath
    }
    $cred = Import-Clixml $CredPath
    $cred.Password = $cred.Password | ConvertTo-SecureString
    $Credential = New-Object System.Management.Automation.PsCredential($cred.UserName, $cred.Password)
    Return $Credential
}

And this one:

#=====================================================================
# Export-Credential
# Usage: Export-Credential $CredentialObject $FileToSaveTo
#=====================================================================
function Export-Credential($cred, $path) {
      $cred = $cred | Select-Object *
      $cred.password = $cred.Password | ConvertFrom-SecureString
      $cred | Export-Clixml $path
}

You use it like this:

$Credentials = Get-MyCredential (join-path ($PsScriptRoot) Syncred.xml)

If the credential file doesnt exist, you will be prompted the first time, at that point it will store the credentials in an encrypted string inside an XML file. The second time you run that line, the xmlfile is there and will be opened automatically.

This has everything you need to know: Get viewport/window size

but in short:

var win = window,
    doc = document,
    docElem = doc.documentElement,
    body = doc.getElementsByTagName('body')[0],
    x = win.innerWidth || docElem.clientWidth || body.clientWidth,
    y = win.innerHeight|| docElem.clientHeight|| body.clientHeight;
alert(x + ' × ' + y);

Fiddle

Please stop editing this answer. It's been edited 22 times now by different people to match their code format preference. It's also been pointed out that this isn't required if you only want to target modern browsers - if so you only need the following:

const width  = window.innerWidth || document.documentElement.clientWidth || 
document.body.clientWidth;
const height = window.innerHeight|| document.documentElement.clientHeight|| 
document.body.clientHeight;

console.log(width, height);

.toString() is available, or just add "" to the end of the int

var x = 3,
    toString = x.toString(),
    toConcat = x + "";

Angular is simply JavaScript at the core.

In our case problem occured due to availability cluster configuration. To solve this issue we had to set MultiSubnetFailover to True in the connection string.

I repeatedly had the same challenge sometime ago. This problem occurs mostly when you are trying to pull from the remote repository and you have some files on your local instance conflicting with the remote version, if you are using git from an IDE such as IntelliJ, you will be prompted and allowed to make a choice if you want to retain your own changes or you prefer the changes in the remote version to overwrite yours'. If you don't make any choice then you fall into this conflict. all you need to do is run:

git merge --abort # The unresolved conflict will be cleared off

And you can continue what you were doing before the break.

Swift 4

let collectionViewLayout = collectionView.collectionViewLayout as? UICollectionViewFlowLayout
collectionViewLayout?.sectionInset = UIEdgeInsetsMake(0, 20, 0, 40) 
collectionViewLayout?.invalidateLayout()

This is how I do it

IList<Customer> customers = repository.GetAll<Customer>();
IEnumerable<SelectListItem> selectList = 
    from c in customers
    select new SelectListItem
    {
        Selected = (c.CustomerID == invoice.CustomerID),
        Text = c.Name,
        Value = c.CustomerID.ToString()
    };

At second glance I'm not sure I know what you are after...

There is another way without using $watch, using angular.copy:

var myApp = angular.module('myApp', []);

myApp.factory('Data', function(){

    var service = {
        FirstName: '',
        setFirstName: function(name) {
            // this is the trick to sync the data
            // so no need for a $watch function
            // call this from anywhere when you need to update FirstName
            angular.copy(name, service.FirstName); 
        }
    };
    return service;
});


// Step 1 Controller
myApp.controller('FirstCtrl', function( $scope, Data ){

});

// Step 2 Controller
myApp.controller('SecondCtrl', function( $scope, Data ){
    $scope.FirstName = Data.FirstName;
});

Delete everything inside your local copy using:

rm -r your_local_svn_dir_path/*

And the revert everything recursively using the below command.

svn revert -R your_local_svn_dir_path

This is way faster than deleting the entire directory and then taking a fresh checkout, because the files are being restored from you local SVN meta data. It doesn't even need a network connection.

From This page, the container dies after running everything correctly but crashes because all the commands ended. Either you make your services run on the foreground, or you create a keep alive script. By doing so, Kubernetes will show that your application is running. We have to note that in the Docker environment, this problem is not encountered. It is only Kubernetes that wants a running app.

Update (an example):

Here's how to avoid CrashLoopBackOff, when launching a Netshoot container:

kubectl run netshoot --image nicolaka/netshoot -- sleep infinity

It depends which version of the .NET Framework you are using. .NET 4.0 made thread management a whole lot easier using Tasks:

class Program
{
    static void Main(string[] args)
    {
        Task task1 = Task.Factory.StartNew(() => doStuff());
        Task task2 = Task.Factory.StartNew(() => doStuff());
        Task task3 = Task.Factory.StartNew(() => doStuff());

        Task.WaitAll(task1, task2, task3);
                Console.WriteLine("All threads complete");
    }

    static void doStuff()
    {
        //do stuff here
    }
}

In previous versions of .NET you could use the BackgroundWorker object, use ThreadPool.QueueUserWorkItem(), or create your threads manually and use Thread.Join() to wait for them to complete:

static void Main(string[] args)
{
    Thread t1 = new Thread(doStuff);
    t1.Start();

    Thread t2 = new Thread(doStuff);
    t2.Start();

    Thread t3 = new Thread(doStuff);
    t3.Start();

    t1.Join();
    t2.Join();
    t3.Join();

    Console.WriteLine("All threads complete");
}

Better way for you

sp_MSForEachDB @command1='USE ?;
SELECT 
    Table_Catalog 
    ,Table_Schema
    ,Table_Name
    ,Column_Name
    ,Data_Type
    ,Character_Maximum_Length
FROM INFORMATION_SCHEMA.COLUMNS
WHERE COLUMN_NAME like ''%ColumnNameHere%'''

After adding an item to a list, you can replace it by writing

list[someIndex] = new MyClass();

You can modify an existing item in the list by writing

list[someIndex].SomeProperty = someValue;

EDIT: You can write

var index = list.FindIndex(c => c.Number == someTextBox.Text);
list[index] = new SomeClass(...);

You should be able to compare them directly.

var date = moment("2013-03-24")
var now = moment();

if (now > date) {
   // date is past
} else {
   // date is future
}

$(document).ready(function() {_x000D_
  _x000D_
  $('.compare').click(function(e) {_x000D_
  _x000D_
    var date = $('#date').val();_x000D_
  _x000D_
    var now = moment();_x000D_
    var then = moment(date);_x000D_
  _x000D_
    if (now > then) {_x000D_
      $('.result').text('Date is past');_x000D_
    } else {_x000D_
      $('.result').text('Date is future');_x000D_
    }_x000D_
_x000D_
  });_x000D_
_x000D_
});

Or, if you want a more general approach - i.e. for nesting up to "levelN":

void Main()
{
    XElement rootElement = XElement.Load(@"c:\events\test.xml");

    Console.WriteLine(GetOutline(0, rootElement));  
}

private string GetOutline(int indentLevel, XElement element)
{
    StringBuilder result = new StringBuilder();

    if (element.Attribute("name") != null)
    {
        result = result.AppendLine(new string(' ', indentLevel * 2) + element.Attribute("name").Value);
    }

    foreach (XElement childElement in element.Elements())
    {
        result.Append(GetOutline(indentLevel + 1, childElement));
    }

    return result.ToString();
}

Try this :

setInterval( function() { $(".me").fadeOut(500).fadeIn(500) } , 500);

If you get this sort of thing appearing suddenly, it usually means the project is missing some frameworks it needs. Libraries and dependent projects can require frameworks, so if you've added one recently then that can cause this error.

To add frameworks, right click on the project name in the project view, select Add, then select Existing frameworks... from the list. Then find the framework with the symbols you're missing.

As to how you find which frameworks you need, I've found using google the easiest, though you could probably use the Xcode help search too. Search for one of the symbols, doing your best to work out the unmangled name (e.g., SCNetworkReachabilityGetFlags), and then the first documentation link you find at developer.apple.com is often the right one. You usually don't have to hunt very far. In this case, that's this page:

https://developer.apple.com/documentation/systemconfiguration/scnetworkreachability-g7d

Then at the top of the page, it tells you which framework to use, SystemConfiguration in this case. So add that to the project, and compile again.

Then just keep doing this until it works...

Edit: I've never used the simulator, but this is what you do on the device - I assume it's the same...

"bad enough not having a traditional for(;;) looper"?? What?

Are you trying to do

import string
for c in string.lowercase:
    ...do something with c...

Or perhaps you're using string.uppercase or string.letters?

Python doesn't have for(;;) because there are often better ways to do it. It also doesn't have character math because it's not necessary, either.

Ok, so this question is nearly 6 years old and I still can't find in here what I think it's the proper answer, so allow me to share my "2 cents"...

I actually have 2 ways of doing it, first one is the simple one...the second on the right one, so if you are looking for the right one, just skip #1 and jump to #2:

1. Quick and Easy (but not complete)

If I have just a small project I sometimes just create a CloseWindowAction in the ViewModel:

        public Action CloseWindow { get; set; } // In MyViewModel.cs

And whoever crates the View, or in the View's code behind I just set the Method the Action will call:

(remember MVVM is about separation of the View and the ViewModel...the View's code behins is still the View and as long as there is proper separation you are not violating the pattern)

If some ViewModel creates a new window:

private void CreateNewView()
{
    MyView window = new MyView();
    window.DataContext = new MyViewModel
                             {
                                 CloseWindow = window.Close,
                             }; 
    window.ShowDialog();
}

Or if you want it in your Main Window, just place it under your View's constructor:

public MyView()
{
    InitializeComponent();           
    this.DataContext = new MainViewModel
                           {
                                CloseWindow = this.Close
                           };
}

when you want to close the window, just call the Action on your ViewModel.

2. The right way

Now the proper way of doing it is using Prism (IMHO), and all about it can be found here.

You can make an Interaction Request, populate it with whatever data you will need in your new Window, lunch it, close it and even receive data back. All of this encapsulated and MVVM approved. You even get a status of how the Window was closed, like if the User Canceled or Accepted (OK button) the Window and data back if you need it. It's a bit more complicated and Answer #1, but it's a lot more complete, and a Recommended Pattern by Microsoft.

The link I gave have all the code snippets and examples, so I won't bother to place any code in here, just read the article of download the Prism Quick Start and run it, it's really simple to understad just a little more verbose to make it work, but the benefits are bigger than just closing a window.

Let's answer your questions one by one.

1. Yes, you make a new object whenever this statement is executed, however, it goes "out of scope" when you exit the method and it is eligible for garbage collection.
2. Well this would be the same as #1, except that you've used a string type. A string type is immutable and you get a new object every time you make an assignment.
3. Yes the garbage collector collects the out of scope objects, unless you assign the object to a variable with a large scope such as class variable.
4. Yes.
5. The using statement only applies to objects that implement the IDisposable interface. If that is the case, by all means using is best for objects within a method's scope. Don't put Foo o at a larger scope unless you have a good reason to do so. It is best to limit the scope of any variable to the smallest scope that makes sense.

The best way to do it is to put the Django admin templates inside your project. So your templates would be in templates/admin while the stock Django admin templates would be in say template/django_admin. Then, you can do something like the following:

templates/admin/change_form.html

{% extends 'django_admin/change_form.html' %}

Your stuff here

If you're worried about keeping the stock templates up to date, you can include them with svn externals or similar.
