Try this query

DECLARE @PrintVarchar nvarchar(max) = (Select Sum(Amount) From Expense)
PRINT 'Varchar format =' + @PrintVarchar

DECLARE @PrintInt int = (Select Sum(Amount) From Expense)
PRINT @PrintInt

The IF/THEN/ELSE construct you are using is only valid in stored procedures and functions. Your query will need to be restructured because you can't use the IF() function to control the flow of the WHERE clause like this.

The IF() function that can be used in queries is primarily meant to be used in the SELECT portion of the query for selecting different data based on certain conditions, not so much to be used in the WHERE portion of the query:

SELECT IF(JQ.COURSE_ID=0, 'Some Result If True', 'Some Result If False'), OTHER_COLUMNS
FROM ...
WHERE ...

If it is a list of parameters from existing SQL table, for example ID list from existing Table1, then you can try this:

select distinct ID
      FROM Table1
      where 
      ID in (1, 1, 1, 2, 5, 1, 6)
ORDER BY ID;

Or, if you need List of parameters as a SQL Table constant(variable), try this:

WITH Id_list AS (
     select ID
      FROM Table1
      where 
      ID in (1, 1, 1, 2, 5, 1, 6)
)
SELECT distinct * FROM Id_list
ORDER BY ID;

Not really, because as you say, the compiler only knows that callFriend() is returning an Animal, not a Dog or Duck.

Can you not add an abstract makeNoise() method to Animal that would be implemented as a bark or quack by its subclasses?

Enum.GetValues(typeof(MyEnum)).Length;

I'm leaning towards the "Is Nothing" alternative, primarily because it seems more OO.

Surely Visual Basic ain't got the Ain't keyword.

You should add "throws IOException" to your main method:

public static void main(String[] args) throws IOException {

You can read a bit more about checked exceptions (which are specific to Java) in JLS.

I like Keith Hill's answer except it has a bug that prevents it from recursing past two levels. These commands manifest the bug:

New-Item level1/level2/level3/level4/foobar.txt -Force -ItemType file
cd level1
GetFiles . xyz | % { $_.fullname }

With Hill's original code you get this:

...\level1\level2
...\level1\level2\level3

Here is a corrected, and slightly refactored, version:

function GetFiles($path = $pwd, [string[]]$exclude)
{
    foreach ($item in Get-ChildItem $path)
    {
        if ($exclude | Where {$item -like $_}) { continue }

        $item
        if (Test-Path $item.FullName -PathType Container)
        {
            GetFiles $item.FullName $exclude
        }
    }
} 

With that bug fix in place you get this corrected output:

...\level1\level2
...\level1\level2\level3
...\level1\level2\level3\level4
...\level1\level2\level3\level4\foobar.txt

I also like ajk's answer for conciseness though, as he points out, it is less efficient. The reason it is less efficient, by the way, is because Hill's algorithm stops traversing a subtree when it finds a prune target while ajk's continues. But ajk's answer also suffers from a flaw, one I call the ancestor trap. Consider a path such as this that includes the same path component (i.e. subdir2) twice:

\usr\testdir\subdir2\child\grandchild\subdir2\doc

Set your location somewhere in between, e.g. cd \usr\testdir\subdir2\child, then run ajk's algorithm to filter out the lower subdir2 and you will get no output at all, i.e. it filters out everything because of the presence of subdir2 higher in the path. This is a corner case, though, and not likely to be hit often, so I would not rule out ajk's solution due to this one issue.

Nonetheless, I offer here a third alternative, one that does not have either of the above two bugs. Here is the basic algorithm, complete with a convenience definition for the path or paths to prune--you need only modify $excludeList to your own set of targets to use it:

$excludeList = @("stuff","bin","obj*")
Get-ChildItem -Recurse | % {
    $pathParts = $_.FullName.substring($pwd.path.Length + 1).split("\");
    if ( ! ($excludeList | where { $pathParts -like $_ } ) ) { $_ }
}

My algorithm is reasonably concise but, like ajk's, it is less efficient than Hill's (for the same reason: it does not stop traversing subtrees at prune targets). However, my code has an important advantage over Hill's--it can pipeline! It is therefore amenable to fit into a filter chain to make a custom version of Get-ChildItem while Hill's recursive algorithm, through no fault of its own, cannot. ajk's algorithm can be adapted to pipeline use as well, but specifying the item or items to exclude is not as clean, being embedded in a regular expression rather than a simple list of items that I have used.

I have packaged my tree pruning code into an enhanced version of Get-ChildItem. Aside from my rather unimaginative name--Get-EnhancedChildItem--I am excited about it and have included it in my open source Powershell library. It includes several other new capabilities besides tree pruning. Furthermore, the code is designed to be extensible: if you want to add a new filtering capability, it is straightforward to do. Essentially, Get-ChildItem is called first, and pipelined into each successive filter that you activate via command parameters. Thus something like this...

Get-EnhancedChildItem –Recurse –Force –Svn
    –Exclude *.txt –ExcludeTree doc*,man -FullName -Verbose 

... is converted internally into this:

Get-ChildItem | FilterExcludeTree | FilterSvn | FilterFullName

Each filter must conform to certain rules: accepting FileInfo and DirectoryInfo objects as inputs, generating the same as outputs, and using stdin and stdout so it may be inserted in a pipeline. Here is the same code refactored to fit these rules:

filter FilterExcludeTree()
{
  $target = $_
  Coalesce-Args $Path "." | % {
    $canonicalPath = (Get-Item $_).FullName
    if ($target.FullName.StartsWith($canonicalPath)) {
      $pathParts = $target.FullName.substring($canonicalPath.Length + 1).split("\");
      if ( ! ($excludeList | where { $pathParts -like $_ } ) ) { $target }
    }
  }
} 

The only additional piece here is the Coalesce-Args function (found in this post by Keith Dahlby), which merely sends the current directory down the pipe in the event that the invocation did not specify any paths.

Because this answer is getting somewhat lengthy, rather than go into further detail about this filter, I refer the interested reader to my recently published article on Simple-Talk.com entitled Practical PowerShell: Pruning File Trees and Extending Cmdlets where I discuss Get-EnhancedChildItem at even greater length. One last thing I will mention, though, is another function in my open source library, New-FileTree, that lets you generate a dummy file tree for testing purposes so you can exercise any of the above algorithms. And when you are experimenting with any of these, I recommend piping to % { $_.fullname } as I did in the very first code fragment for more useful output to examine.

The only thing that worked for me was to delete the Solution User Options (.suo) file. Note that, this is a hidden file.

To locate this file, close your Virsual studio and search for .suo from the file explorer within your project.

PS: a new .suo file will be created again when you rebuild your project and hopefully this newly created one wont give you issues.

I hope that helps someone get rid of this anoying error :).

A unique constraint can't be over 8000 bytes per row and will only use the first 900 bytes even then so the safest maximum size for your keys would be:

create table [misc_info]
( 
    [id] INTEGER PRIMARY KEY IDENTITY NOT NULL, 
    [key] nvarchar(450) UNIQUE NOT NULL, 
    [value] nvarchar(max) NOT NULL
)

i.e. the key can't be over 450 characters. If you can switch to varchar instead of nvarchar (e.g. if you don't need to store characters from more than one codepage) then that could increase to 900 characters.

How about

sudo yum install php-mysql

or

sudo apt-get install php5-mysql

This will not change the default schema in Oracle Sql Developer but I wanted to point out that it is easy to quickly view another user schema, right click the Database Connection:

Select the user to see the schema for that user

In the top level of the IIS Manager (above Sites), you should see the Application Pools tree node. Right click on "Application Pools", choose "Add Application Pool".

Give it a name, choose .NET Framework 4.0 and either Integrated or Classic mode.

When you add or edit a web site, your new application pools will now show up in the list.

I have found answers to my confusions.

There is a very important difference between the root and the alias directives. This difference exists in the way the path specified in the root or the alias is processed.

In case of the root directive, full path is appended to the root including the location part, whereas in case of the alias directive, only the portion of the path NOT including the location part is appended to the alias.

To illustrate:

Let's say we have the config

location /static/ {
    root /var/www/app/static/;
    autoindex off;
}

In this case the final path that Nginx will derive will be

/var/www/app/static/static

This is going to return 404 since there is no static/ within static/

This is because the location part is appended to the path specified in the root. Hence, with root, the correct way is

location /static/ {
    root /var/www/app/;
    autoindex off;
}

On the other hand, with alias, the location part gets dropped. So for the config

location /static/ {
    alias /var/www/app/static/;
    autoindex off;           ?
}                            |
                             pay attention to this trailing slash

the final path will correctly be formed as

/var/www/app/static

The case of trailing slash for alias directive

There is no definitive guideline about whether a trailing slash is mandatory per Nginx documentation, but a common observation by people here and elsewhere seems to indicate that it is.

A few more places have discussed this, not conclusively though.

In a Ruby on Rails project by default the root of the HTML source for the server is the public directory. So your link would be:

<img src="images/rss.jpg" alt="rss feed" />

But it is best practice in a Rails project to use the built in helper:

<%= image_tag("rss.jpg", :alt => "rss feed") %>

That will create the correct image link plus if you ever add assert servers, etc it will work with those.

I hope this answers the intent of the question. Although there are no Booleans in SQL Server, if you have a database that had Boolean types that was translated from Access, the phrase which works in Access was "...WHERE Foo" (Foo is the Boolean column name). It can be replaced by "...WHERE Foo<>0" ... and this works. Good luck!

you have to first download the get-pip.py and then run the command :

python get-pip.py

I do not find a perfect way in Android Studio, get the process id and kill it from terminal:

ps -e | grep adb
kill -9 pid_adb

This might be a very late reply but it is working for us. We are using the same gallery provided by Android, just that, we have adjusted the left margin such a way that the screens left end is considered as Gallery's center. That really worked well for us.

You may have this issue as well if you have environment variable GCC_ROOT pointing to a wrong location. Probably simplest fix could be (on *nix like system):

unset GCC_ROOT

in more complicated cases you may need to repoint it to proper location

For WSL (Windows Subsystem for Linux) you need install build-essential package:

sudo apt install build-essential

Assuming you mean UNIX shell commands, just run

echo >> file.txt

echo prints a newline, and the >> tells the shell to append that newline to the file, creating if it doesn't already exist.

In order to properly answer the question, though, I'd need to know what you would want to happen if the file already does exist. If you wanted to replace its current contents with the newline, for example, you would use

echo > file.txt

EDIT: and in response to Justin's comment, if you want to add the newline only if the file didn't already exist, you can do

test -e file.txt || echo > file.txt

At least that works in Bash, I'm not sure if it also does in other shells.

These are the steps I took to make an image transparent:

1- I used an online website which makes the image transparent, there are a lot of them. For me, I use this https://www241.lunapic.com/editor/?action=transparent and sometimes this http://www.online-image-editor.com/help/transparency

2- In Android Studio (I'm using version 3.1.3), open Image Asset from app > res (right click) > New > Image Asset

3- In the Path, choose the location of the transparent image which you downloaded from the online website, and make the other options as shown, then Next, then Finish. The five different sizes of image mdpi(48×48), hdpi(72×72), xhdpi(96×96), xxhdpi(144×144), and xxxhdpi(192×192) will be created in the res/mipmap-density folders.

4- If you need sizes (dimensions) different from above, you can use this website http://nsimage.brosteins.com/ to upload your PNG image of biggest size that will be used in xxxhdpi. After uploading, you can download a zip file containing the five different sizes of image in the res/drawable-density folders.

Ahti Kitsik's plugin is mentioned above, but there's a newer plugin by another author that works with newer versions of Eclipse (up to Juno, at least), and also fixed the line numbering issue in the older plugin.

Full installation instructions are at Eclipse version to download the word wrap plug-in

It's totally feasible now. Google now allow you to transfer Android apps between accounts. Please take a look at this link: https://support.google.com/googleplay/android-developer/checklist/3294213?hl=en

Just to expand on pcperini's answer. As he mentions you will need to add the following code to your application:didFinishLaunchingWithOptions: method;

[[UIApplication sharedApplication] setApplicationIconBadgeNumber: 0];
[[UIApplication sharedApplication] cancelAllLocalNotifications];

You Also need to increment then decrement the badge in your application:didReceiveRemoteNotification: method if you are trying to clear the message from the message centre so that when a user enters you app from pressing a notification the message centre will also clear, ie;

[[UIApplication sharedApplication] setApplicationIconBadgeNumber: 1];
[[UIApplication sharedApplication] setApplicationIconBadgeNumber: 0];
[[UIApplication sharedApplication] cancelAllLocalNotifications];

What you need to do is configure Fiddler to work as a "reverse proxy"

There are instructions on 2 different ways you can do this on Fiddler's website. Here is a copy of the steps:

Step #0

Before either of the following options will work, you must enable other computers to connect to Fiddler. To do so, click Tools > Fiddler Options > Connections and tick the "Allow remote computers to connect" checkbox. Then close Fiddler.

Option #1: Configure Fiddler as a Reverse-Proxy

Fiddler can be configured so that any traffic sent to http://127.0.0.1:8888 is automatically sent to a different port on the same machine. To set this configuration:

1. Start REGEDIT
2. Create a new DWORD named ReverseProxyForPort inside HKCU\SOFTWARE\Microsoft\Fiddler2.
3. Set the DWORD to the local port you'd like to re-route inbound traffic to (generally port 80 for a standard HTTP server)
4. Restart Fiddler
5. Navigate your browser to http://127.0.0.1:8888

Option #2: Write a FiddlerScript rule

Alternatively, you can write a rule that does the same thing.

Say you're running a website on port 80 of a machine named WEBSERVER. You're connecting to the website using Internet Explorer Mobile Edition on a Windows SmartPhone device for which you cannot configure the web proxy. You want to capture the traffic from the phone and the server's response.

1. Start Fiddler on the WEBSERVER machine, running on the default port of 8888.
2. Click Tools | Fiddler Options, and ensure the "Allow remote clients to connect" checkbox is checked. Restart if needed.
3. Choose Rules | Customize Rules.
4. Inside the OnBeforeRequest handler, add a new line of code:
   if (oSession.host.toLowerCase() == "webserver:8888") oSession.host = "webserver:80";
5. On the SmartPhone, navigate to http://webserver:8888

Requests from the SmartPhone will appear in Fiddler. The requests are forwarded from port 8888 to port 80 where the webserver is running. The responses are sent back through Fiddler to the SmartPhone, which has no idea that the content originally came from port 80.

Regex to the rescue!

import re

s = re.sub('[^0-9a-zA-Z]+', '*', s)

Example:

>>> re.sub('[^0-9a-zA-Z]+', '*', 'h^&ell`.,|o w]{+orld')
'h*ell*o*w*orld'

If both arrays are in the correct order; where each item corresponds to its associated member identifier then you can simply use.

var merge = _.merge(arr1, arr2);

Which is the short version of:

var merge = _.chain(arr1).zip(arr2).map(function(item) {
    return _.merge.apply(null, item);
}).value();

Or, if the data in the arrays is not in any particular order, you can look up the associated item by the member value.

var merge = _.map(arr1, function(item) {
    return _.merge(item, _.find(arr2, { 'member' : item.member }));
});

You can easily convert this to a mixin. See the example below:

_.mixin({_x000D_
  'mergeByKey' : function(arr1, arr2, key) {_x000D_
    var criteria = {};_x000D_
    criteria[key] = null;_x000D_
    return _.map(arr1, function(item) {_x000D_
      criteria[key] = item[key];_x000D_
      return _.merge(item, _.find(arr2, criteria));_x000D_
    });_x000D_
  }_x000D_
});_x000D_
_x000D_
var arr1 = [{_x000D_
  "member": 'ObjectId("57989cbe54cf5d2ce83ff9d6")',_x000D_
  "bank": 'ObjectId("575b052ca6f66a5732749ecc")',_x000D_
  "country": 'ObjectId("575b0523a6f66a5732749ecb")'_x000D_
}, {_x000D_

  "bank": 'ObjectId("575b052ca6f66a5732749ecc")',_x000D_
  "country": 'ObjectId("575b0523a6f66a5732749ecb")'_x000D_
}];_x000D_
_x000D_
var arr2 = [{_x000D_
  "member": 'ObjectId("57989cbe54cf5d2ce83ff9d8")',_x000D_
  "name": 'yyyyyyyyyy',_x000D_
  "age": 26_x000D_
}, {_x000D_
  "member": 'ObjectId("57989cbe54cf5d2ce83ff9d6")',_x000D_
  "name": 'xxxxxx',_x000D_
  "age": 25_x000D_
}];_x000D_
_x000D_
var arr3 = _.mergeByKey(arr1, arr2, 'member');_x000D_
_x000D_
document.body.innerHTML = JSON.stringify(arr3, null, 4);

based on other answers here I'd like to share my one-liners that should work for dirs and files:

• Len(Dir(path)) > 0 or Or Len(Dir(path, vbDirectory)) > 0  'version 1 - ... <> "" should be more inefficient generally
  

  • (just Len(Dir(path)) did not work for directories (Excel 2010 / Win7))

• CreateObject("Scripting.FileSystemObject").FileExists(path)  'version 2 - could be faster sometimes, but only works for files (tested on Excel 2010/Win7)
  

as PathExists(path) function:

Public Function PathExists(path As String) As Boolean
    PathExists = Len(Dir(path)) > 0 Or Len(Dir(path, vbDirectory)) > 0
End Function

In case you don't have access to functools.partial, you could use a wrapper function for this, as well.

def target(lock):
    def wrapped_func(items):
        for item in items:
            # Do cool stuff
            if (... some condition here ...):
                lock.acquire()
                # Write to stdout or logfile, etc.
                lock.release()
    return wrapped_func

def main():
    iterable = [1, 2, 3, 4, 5]
    pool = multiprocessing.Pool()
    lck = multiprocessing.Lock()
    pool.map(target(lck), iterable)
    pool.close()
    pool.join()

This makes target() into a function that accepts a lock (or whatever parameters you want to give), and it will return a function that only takes in an iterable as input, but can still use all your other parameters. That's what is ultimately passed in to pool.map(), which then should execute with no problems.

As written, your function accepts only two ranges as arguments.

To allow for a variable number of ranges to be used in the function, you need to declare a ParamArray variant array in your argument list. Then, you can process each of the ranges in the array in turn.

For example,

Function myAdd(Arg1 As Range, ParamArray Args2() As Variant) As Double
    Dim elem As Variant
    Dim i As Long
    For Each elem In Arg1
        myAdd = myAdd + elem.Value
    Next elem
    For i = LBound(Args2) To UBound(Args2)
        For Each elem In Args2(i)
            myAdd = myAdd + elem.Value
        Next elem
    Next i
End Function

This function could then be used in the worksheet to add multiple ranges.

For your function, there is the question of which of the ranges (or cells) that can passed to the function are 'Sessions' and which are 'Customers'.

The easiest case to deal with would be if you decided that the first range is Sessions and any subsequent ranges are Customers.

Function calculateIt(Sessions As Range, ParamArray Customers() As Variant) As Double
    'This function accepts a single Sessions range and one or more Customers
    'ranges
    Dim i As Long
    Dim sessElem As Variant
    Dim custElem As Variant
    For Each sessElem In Sessions
        'do something with sessElem.Value, the value of each
        'cell in the single range Sessions
        Debug.Print "sessElem: " & sessElem.Value
    Next sessElem
    'loop through each of the one or more ranges in Customers()
    For i = LBound(Customers) To UBound(Customers)
        'loop through the cells in the range Customers(i)
        For Each custElem In Customers(i)
            'do something with custElem.Value, the value of
            'each cell in the range Customers(i)
            Debug.Print "custElem: " & custElem.Value
         Next custElem
    Next i
End Function

If you want to include any number of Sessions ranges and any number of Customers range, then you will have to include an argument that will tell the function so that it can separate the Sessions ranges from the Customers range.

This argument could be set up as the first, numeric, argument to the function that would identify how many of the following arguments are Sessions ranges, with the remaining arguments implicitly being Customers ranges. The function's signature would then be:

Function calculateIt(numOfSessionRanges, ParamAray Args() As Variant)

Or it could be a "guard" argument that separates the Sessions ranges from the Customers ranges. Then, your code would have to test each argument to see if it was the guard. The function would look like:

Function calculateIt(ParamArray Args() As Variant)

Perhaps with a call something like:

calculateIt(sessRange1,sessRange2,...,"|",custRange1,custRange2,...)

The program logic might then be along the lines of:

Function calculateIt(ParamArray Args() As Variant) As Double
   ...
   'loop through Args
   IsSessionArg = True
   For i = lbound(Args) to UBound(Args)
       'only need to check for the type of the argument
       If TypeName(Args(i)) = "String" Then
          IsSessionArg = False
       ElseIf IsSessionArg Then
          'process Args(i) as Session range
       Else
          'process Args(i) as Customer range
       End if
   Next i
   calculateIt = <somevalue>
End Function

Haven't tried it yet, but Configgy looks promising for both configuration and logging:

Here's a way to get dimensions of a png file without needing a third-party module. From http://coreygoldberg.blogspot.com/2013/01/python-verify-png-file-and-get-image.html

import struct

def get_image_info(data):
    if is_png(data):
        w, h = struct.unpack('>LL', data[16:24])
        width = int(w)
        height = int(h)
    else:
        raise Exception('not a png image')
    return width, height

def is_png(data):
    return (data[:8] == '\211PNG\r\n\032\n'and (data[12:16] == 'IHDR'))

if __name__ == '__main__':
    with open('foo.png', 'rb') as f:
        data = f.read()

    print is_png(data)
    print get_image_info(data)

When you run this, it will return:

True
(x, y)

This is an old question, but I thought I'd put in my C# 6 answer. I often have to set up test data that is easily entered in-code as a list of tuples. With a couple of extension functions, it is possible to have this nice, compact format, without repeating the names on each entry.

var people= new List<Tuple<int, int, string>>() {
    {1, 11, "Adam"},
    {2, 22, "Bill"},
    {3, 33, "Carol"}
}.Select(t => new { Id = t.Item1, Age = t.Item2, Name = t.Item3 });

This gives an IEnumerable - if you want a list that you can add to then just add ToList().

The magic comes from custom extension Add methods for tuples, as described at https://stackoverflow.com/a/27455822/4536527.

public static class TupleListExtensions    {
    public static void Add<T1, T2>(this IList<Tuple<T1, T2>> list,
            T1 item1, T2 item2)       {
        list.Add(Tuple.Create(item1, item2));
    }

    public static void Add<T1, T2, T3>(this IList<Tuple<T1, T2, T3>> list,
            T1 item1, T2 item2, T3 item3) {
        list.Add(Tuple.Create(item1, item2, item3));
    }

// and so on...

}

The only thing I don't like is that the types are separated from the names, but if you really don't want to make a new class then this approach will still let you have readable data.

@Override
public void onDraw(Canvas canvas){
    canvas.drawCircle(xPos, yPos,radius, paint);
}

Above is the code to render a circle. Tweak the parameters to your suiting.

To answer all your questions:

Can I use ROBOCOPY for this?

Yes, RC should fit your requirements (simplicity, only copy what needed)

What exactly does it mean to exclude?

It will exclude copying - RC calls it skipping

Would the /XO option copy only newer files, not files of the same age?

Yes, RC will only copy newer files. Files of the same age will be skipped.

(the correct command would be robocopy C:\SourceFolder D:\DestinationFolder ABC.dll /XO)

Maybe in your case using the /MIR option could be useful. In general RC is rather targeted at directories and directory trees than single files.

I think you try to get the remote host of the conneting user...

You can get a String like 'myuser@localhost' from the command:

SELECT USER()

You can split this result on the '@' sign, to get the parts:

-- delivers the "remote_host" e.g. "localhost" 
SELECT SUBSTRING_INDEX(USER(), '@', -1) 

-- delivers the user-name e.g. "myuser"
SELECT SUBSTRING_INDEX(USER(), '@', 1)

if you are conneting via ip address you will get the ipadress instead of the hostname.

I'm a bit newer to Angular but what I found useful to do (and pretty simple) is I made a global script that I load onto my page before the local script with global variables that I need to access on all pages anyway. In that script, I created an object called "globalFunctions" and added the functions that I need to access globally as properties. e.g. globalFunctions.foo = myFunc();. Then, in each local script, I wrote $scope.globalFunctions = globalFunctions; and I instantly have access to any function I added to the globalFunctions object in the global script.

This is a bit of a workaround and I'm not sure it helps you but it definitely helped me as I had many functions and it was a pain adding all of them to each page.

If you lost a keystore file, don't create/update the new one with another set of value. First do the thorough search. Because it will overwrite the old one, so it will not match to your previous apk.

If you use eclipse most probably it will store in default path. For MAC (eclipse) it will be in your elispse installation path something like:

/Applications/eclipse/Eclipse.app/Contents/MacOS/

then your keystore file without any extension. You need root privilege to access this path (file).

Maybe a shorter version, would be easier to understand?

You need to use background-size: 100% 100%;

Demo

Demo 2 (Won't stretch, this is what you are doing)

Explanation: You need to use 100% 100% as it sets for X AS WELL AS Y, you are setting 100% just for the X parameter, thus the background doesn't stretch vertically.

Still, the image will stretch out, it won't be responsive, if you want to stretch the background proportionately, you can look for background-size: cover; but IE will create trouble for you here as it's CSS3 property, but yes, you can use CSS3 Pie as a polyfill. Also, using cover will crop your image.

Java doesn't pass objects, it passes references (pointers) to objects. So yes, l2 and l1 are two pointers to the same object.

You have to make an explicit copy if you need two different list with the same contents.

Convert the image to a byte[] and store that in the database.

Add this column to your model:

public byte[] Content { get; set; }

Then convert your image to a byte array and store that like you would any other data:

public byte[] ImageToByteArray(System.Drawing.Image imageIn)
{
    using(var ms = new MemoryStream())
    {
        imageIn.Save(ms, System.Drawing.Imaging.ImageFormat.Gif);

        return ms.ToArray();
    }
}

public Image ByteArrayToImage(byte[] byteArrayIn)
{
     using(var ms = new MemoryStream(byteArrayIn))
     {
         var returnImage = Image.FromStream(ms);

         return returnImage;
     }
}

Source: Fastest way to convert Image to Byte array

var image = new ImageEntity()
{
   Content = ImageToByteArray(image)
};

_context.Images.Add(image);
_context.SaveChanges();

When you want to get the image back, get the byte array from the database and use the ByteArrayToImage and do what you wish with the Image

This stops working when the byte[] gets to big. It will work for files under 100Mb

NOTE: I had intended this as an answer, but further testing reveals it still fails when built using maven from the command line, so I've had to edit it to be a problem! :-(

In my case when I got this error I was already using a AppCompat Theme and the error didn't make much sense.

I was in the process of mavenizing my android build. I had already dependencies on the apklib and jar versions of app compat, thus:

    <!-- See https://github.com/mosabua/maven-android-sdk-deployer -->
        <dependency>
            <groupId>android.support</groupId>
            <artifactId>compatibility-v7-appcompat</artifactId>
            <version>${compatibility.version}</version>
            <type>apklib</type>
        </dependency>

        <dependency>

Now, when I import the maven project and build and run from IntelliJ it's fine.

But when I build and deploy and run from the command line with maven I still get this exception.

Somebody can explain to me why 'NULL' is not just a string in a comparison instance?

$x = 0;
var_dump($x == 'NULL');  # TRUE   !!!WTF!!!

I deleted the 20-mongo.ini file in /etc/php5/cli/conf.d and this solved the problem.

Some JavaScript engines can parse that format directly, which makes the task pretty easy:

function convertDate(inputFormat) {_x000D_
  function pad(s) { return (s < 10) ? '0' + s : s; }_x000D_
  var d = new Date(inputFormat)_x000D_
  return [pad(d.getDate()), pad(d.getMonth()+1), d.getFullYear()].join('/')_x000D_
}_x000D_
_x000D_
console.log(convertDate('Mon Nov 19 13:29:40 2012')) // => "19/11/2012"

i solved problem changing my.ini file located in data folder. for mysql 5.6 my.ini file moved to data folder rather the bin or mysql installation folder.

It's shorthand for tags.map(&:name.to_proc).join(' ')

If foo is an object with a to_proc method, then you can pass it to a method as &foo, which will call foo.to_proc and use that as the method's block.

The Symbol#to_proc method was originally added by ActiveSupport but has been integrated into Ruby 1.8.7. This is its implementation:

class Symbol
  def to_proc
    Proc.new do |obj, *args|
      obj.send self, *args
    end
  end
end

You can get all the contact all those which have no number and all those which have no name from this piece of code

public void readContacts() {
    ContentResolver cr = getContentResolver();
    Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,
            null, null, null, ContactsContract.RawContacts.DISPLAY_NAME_PRIMARY + " ASC");
    ContactCount = cur.getCount();

    if (cur.getCount() > 0) {
        while (cur.moveToNext()) {
            String id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID));
            String name = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
            String phone = null;
            if (Integer.parseInt(cur.getString(cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
                System.out.println("name : " + name + ", ID : " + id);

                // get the phone number
                Cursor pCur = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,
                        ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?",
                        new String[]{id}, null);
                while (pCur.moveToNext()) {
                    phone = pCur.getString(
                            pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
                    System.out.println("phone" + phone);
                }
                pCur.close();
            }
            if (phone == "" || name == "" || name.equals(phone)) {
                if (phone.equals(""))
                    getAllContact.add(new MissingPhoneModelClass("No Number", name, id));
                if (name.equals("") || name.equals(phone))
                    getAllContact.add(new MissingPhoneModelClass(phone, "No Name", id));

            } else {
                if(TextUtils.equals(phone,null)){
                    getAllContact.add(new MissingPhoneModelClass("No Number", name, id));
                }
                else {
                    getAllContact.add(new MissingPhoneModelClass(phone, name, id));
                }
            }
        }
    }
}

One thing can be done you have to give the permission in the manifest for contact READ and WRITE After that you can create the model class for the list which can be use to add all the contact here is the model class

public class PhoneModelClass {
private String number;
private String name;
private String id;
private String rawId;

public PhoneModelClass(String number, String name, String id, String rawId) {
    this.number = number;
    this.name = name;
    this.id = id;
    this.rawId = rawId;
}

public PhoneModelClass(String number, String name, String id) {
    this.number = number;
    this.name = name;
    this.id = id;
}

public String getRawId() {
    return rawId;
}

public void setRawId(String rawId) {
    this.rawId = rawId;
}

public String getNumber() {
    return number;
}

public void setNumber(String number) {
    this.number = number;
}

public String getName() {
    return name;
}

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

public String getId() {
    return id;
}

public void setId(String id) {
    this.id = id;
  }
}

Enjoy :)

It's really hard to tell, but one of the 9001 ads on the page may be clobbering the $ object.

jQuery provides the global jQuery object (which is present on your page). You can do the following to "get" $ back:

jQuery(document).ready(function ($) {
    // Your code here
});

If you think you're having jQuery problems, please use the debug (non-production) versions of the library.

Also, it's probably not best to be editing a live site like that ...

1. PSYoungGen refers to the garbage collector in use for the minor collection. PS stands for Parallel Scavenge.
2. The first set of numbers are the before/after sizes of the young generation and the second set are for the entire heap. (Diagnosing a Garbage Collection problem details the format)
3. The name indicates the generation and collector in question, the second set are for the entire heap.

An example of an associated full GC also shows the collectors used for the old and permanent generations:

3.757: [Full GC [PSYoungGen: 2672K->0K(35584K)] 
            [ParOldGen: 3225K->5735K(43712K)] 5898K->5735K(79296K) 
            [PSPermGen: 13533K->13516K(27584K)], 0.0860402 secs]

Finally, breaking down one line of your example log output:

8109.128: [GC [PSYoungGen: 109884K->14201K(139904K)] 691015K->595332K(1119040K), 0.0454530 secs]

• 107Mb used before GC, 14Mb used after GC, max young generation size 137Mb
• 675Mb heap used before GC, 581Mb heap used after GC, 1Gb max heap size
• minor GC occurred 8109.128 seconds since the start of the JVM and took 0.04 seconds

In MVC, View screen is calling method which is in Controller or Repository.cs and assigning return value to any control in CSHTML but that method is actually not implemented in .cs/controller, then CSHTML will throw the NULL parameter exception

    public static bool IsPositive<T>(T value)
        where T : struct, IComparable<T>
    {
        return value.CompareTo(default(T)) > 0;
    }

Just to addup on the Field solution (the setAccessible) so that you can access private variable of an object:

public static void dd(Object obj) throws IllegalArgumentException, IllegalAccessException {
    Field[] fields = obj.getClass().getDeclaredFields();
    for (int i=0; i<fields.length; i++)
    {
        fields[i].setAccessible(true);
        System.out.println(fields[i].getName() + " - " + fields[i].get(obj));
    } 

}

You need to correctly separate static data from instance data. In your code, onLoan and setLoanItem() are instance members. If you want to reference/call them you must do so via an instance. So you either want

public void loanItem() {
    this.media.setLoanItem("Yes");
}

or

public void loanItem(Media object) {
    object.setLoanItem("Yes");
}

depending on how you want to pass that instance around.

If you're wanting to do this via powershell on windows this worked for me

$env:JPDA_SUSPEND="y"

You can also use Comparator.comparing(Function, Comparator)
It is convenient to chain comparators when necessary, e.g.:

Comparator<SomeEntity> ENTITY_COMPARATOR = comparing(SomeEntity::getProperty1, reverseOrder())
        .thenComparingInt(SomeEntity::getProperty2)
        .thenComparing(SomeEntity::getProperty3, reverseOrder());

Since my tableView is full of all kinds of insets, this was the only thing that worked well:

Swift 3

if tableView.numberOfSections > 0 && tableView.numberOfRows(inSection: 0) > 0 {
  tableView.scrollToRow(at: IndexPath(row: 0, section: 0), at: .top, animated: true)
}

Swift 2

if tableView.numberOfSections > 0 && tableView.numberOfRowsInSection(0) > 0 {
  tableView.scrollToRowAtIndexPath(NSIndexPath(forRow: 0, inSection: 0), atScrollPosition: .Top, animated: true)
}

declare @starttime datetime = '2012-03-07 22:58:00'

SELECT BookingId, StartTime
FROM Booking
WHERE ABS( DATEDIFF( minute, StartTime, @starttime ) ) <= 60

Here's an old discussion thread where I listed the main differences and the conditions in which you should use each of these methods. I think you may find it useful to go through the discussion.

To explain the differences as relevant to your posted example:

a. When you use RegisterStartupScript, it will render your script after all the elements in the page (right before the form's end tag). This enables the script to call or reference page elements without the possibility of it not finding them in the Page's DOM.

Here is the rendered source of the page when you invoke the RegisterStartupScript method:

<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1"><title></title></head>
<body>
    <form name="form1" method="post" action="StartupScript.aspx" id="form1">
        <div>
            <input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="someViewstategibberish" />
        </div>
        <div> <span id="lblDisplayDate">Label</span>
            <br />
            <input type="submit" name="btnPostback" value="Register Startup Script" id="btnPostback" />
            <br />
            <input type="submit" name="btnPostBack2" value="Register" id="btnPostBack2" />
        </div>
        <div>
            <input type="hidden" name="__EVENTVALIDATION" id="__EVENTVALIDATION" value="someViewstategibberish" />
        </div>
        <!-- Note this part -->
        <script language='javascript'>
            var lbl = document.getElementById('lblDisplayDate');
            lbl.style.color = 'red';
        </script>
    </form>
    <!-- Note this part -->
</body>
</html>

b. When you use RegisterClientScriptBlock, the script is rendered right after the Viewstate tag, but before any of the page elements. Since this is a direct script (not a function that can be called, it will immediately be executed by the browser. But the browser does not find the label in the Page's DOM at this stage and hence you should receive an "Object not found" error.

Here is the rendered source of the page when you invoke the RegisterClientScriptBlock method:

<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1"><title></title></head>
<body>
    <form name="form1" method="post" action="StartupScript.aspx" id="form1">
        <div>
            <input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="someViewstategibberish" />
        </div>
        <script language='javascript'>
            var lbl = document.getElementById('lblDisplayDate');
            // Error is thrown in the next line because lbl is null.
            lbl.style.color = 'green';

Therefore, to summarize, you should call the latter method if you intend to render a function definition. You can then render the call to that function using the former method (or add a client side attribute).

Edit after comments:

For instance, the following function would work:

protected void btnPostBack2_Click(object sender, EventArgs e) 
{ 
  System.Text.StringBuilder sb = new System.Text.StringBuilder(); 
  sb.Append("<script language='javascript'>function ChangeColor() {"); 
  sb.Append("var lbl = document.getElementById('lblDisplayDate');"); 
  sb.Append("lbl.style.color='green';"); 
  sb.Append("}</script>"); 

  //Render the function definition. 
  if (!ClientScript.IsClientScriptBlockRegistered("JSScriptBlock")) 
  {
    ClientScript.RegisterClientScriptBlock(this.GetType(), "JSScriptBlock", sb.ToString()); 
  }

  //Render the function invocation. 
  string funcCall = "<script language='javascript'>ChangeColor();</script>"; 

  if (!ClientScript.IsStartupScriptRegistered("JSScript"))
  { 
    ClientScript.RegisterStartupScript(this.GetType(), "JSScript", funcCall); 
  } 
} 

With absolute or relative positioning, you can do all sorts of overlapping. You've probably want the logo to be styled as such:

div#logo {
  position: absolute;
  left: 100px; // or whatever
}

Note: absolute position has its eccentricities. You'll probably have to experiment a little, but it shouldn't be too hard to do what you want.

It's a ProgressDialog, with setIndeterminate(true).

From http://developer.android.com/guide/topics/ui/dialogs.html#ProgressDialog

ProgressDialog dialog = ProgressDialog.show(MyActivity.this, "", 
                    "Loading. Please wait...", true);

An indeterminate progress bar doesn't actually show a bar, it shows a spinning activity circle thing. I'm sure you know what I mean :)

SIMPLIEST WAY TO HANDLE TIMEOUT LOOP

function myFunc (terminator = false) {
    if(terminator) {
        clearTimeout(timeOutVar);
    } else {
        // do something
        timeOutVar = setTimeout(function(){myFunc();}, 1000);
    }
}   
myFunc(true); //  -> start loop
myFunc(false); //  -> end loop

control + shift + F will do the work

What should happen if there are more than 1 longest string (think '12', and '01')?

Try that to get the longest element

max_length,longest_element = max([(len(x),x) for x in ('a','b','aa')])

And then regular foreach

for st in mylist:
    if len(st)==max_length:...

Just put this in the first line of your script :

#!/usr/bin/env python

Make the file executable with

chmod +x myfile.py

Execute with

./myfile.py

The soft keyboard kept rising even though I set EditorInfo.TYPE_NULL to the view. None of the answers worked for me, except the idea I got from nik431's answer:

editText.setCursorVisible(false);
editText.setFocusableInTouchMode(false);
editText.setFocusable(false);

Here's a bash shell script I created to make Laravel 5 facades very quickly.

Run this in your Laravel 5 installation directory.

Call it like this:

make_facade.sh -f <facade_name> -n '<namespace_prefix>'

Example:

make_facade.sh -f helper -n 'App\MyApp'

If you run that example, it will create the directories Facades and Providers under 'your_laravel_installation_dir/app/MyApp'.

It will create the following 3 files and will also output them to the screen:

./app/MyApp/Facades/Helper.php
./app/MyApp/Facades/HelperFacade.php
./app/MyApp/Providers/HelperServiceProvider.php

After it is done, it will display a message similar to the following:

===========================
    Finished
===========================

Add these lines to config/app.php:
----------------------------------
Providers: App\MyApp\Providers\HelperServiceProvider,
Alias: 'Helper' => 'App\MyApp\Facades\HelperFacade',

So update the Providers and Alias list in 'config/app.php'

Run composer -o dumpautoload

The "./app/MyApp/Facades/Helper.php" will originally look like this:

<?php

namespace App\MyApp\Facades;


class Helper
{
    //
}

Now just add your methods in "./app/MyApp/Facades/Helper.php".

Here is what "./app/MyApp/Facades/Helper.php" looks like after I added a Helper function.

<?php

namespace App\MyApp\Facades;

use Request;

class Helper
{
    public function isActive($pattern = null, $include_class = false)
    {
        return ((Request::is($pattern)) ? (($include_class) ? 'class="active"' : 'active' ) : '');
    }
}

This is how it would be called:
===============================

{!!  Helper::isActive('help', true) !!}

This function expects a pattern and can accept an optional second boolean argument.

If the current URL matches the pattern passed to it, it will output 'active' (or 'class="active"' if you add 'true' as a second argument to the function call).

I use it to highlight the menu that is active.

Python 3 has the facility of Launching parallel tasks. This makes our work easier.

It has for thread pooling and Process pooling.

The following gives an insight:

ThreadPoolExecutor Example

import concurrent.futures
import urllib.request

URLS = ['http://www.foxnews.com/',
        'http://www.cnn.com/',
        'http://europe.wsj.com/',
        'http://www.bbc.co.uk/',
        'http://some-made-up-domain.com/']

# Retrieve a single page and report the URL and contents
def load_url(url, timeout):
    with urllib.request.urlopen(url, timeout=timeout) as conn:
        return conn.read()

# We can use a with statement to ensure threads are cleaned up promptly
with concurrent.futures.ThreadPoolExecutor(max_workers=5) as executor:
    # Start the load operations and mark each future with its URL
    future_to_url = {executor.submit(load_url, url, 60): url for url in URLS}
    for future in concurrent.futures.as_completed(future_to_url):
        url = future_to_url[future]
        try:
            data = future.result()
        except Exception as exc:
            print('%r generated an exception: %s' % (url, exc))
        else:
            print('%r page is %d bytes' % (url, len(data)))

Another Example

import concurrent.futures
import math

PRIMES = [
    112272535095293,
    112582705942171,
    112272535095293,
    115280095190773,
    115797848077099,
    1099726899285419]

def is_prime(n):
    if n % 2 == 0:
        return False

    sqrt_n = int(math.floor(math.sqrt(n)))
    for i in range(3, sqrt_n + 1, 2):
        if n % i == 0:
            return False
    return True

def main():
    with concurrent.futures.ThreadPoolExecutor(max_workers=5) as executor:
        for number, prime in zip(PRIMES, executor.map(is_prime, PRIMES)):
            print('%d is prime: %s' % (number, prime))

if __name__ == '__main__':
    main()

::: works only with lists, while ++ can be used with any traversable. In the current implementation (2.9.0), ++ falls back on ::: if the argument is also a List.

//Secure & Encrypte Data
    public static string HashSHA1(string value)
    {
        var sha1 = SHA1.Create();
        var inputBytes = Encoding.ASCII.GetBytes(value);
        var hash = sha1.ComputeHash(inputBytes);
        var sb = new StringBuilder();
        for (var i = 0; i < hash.Length; i++)
        {
            sb.Append(hash[i].ToString("X2"));
        }
        return sb.ToString();
    }

My situation was a little complicated. I had to do three steps since I was using a .dll in the resources directory, for JNI code. My files were

S:\Accessibility\tools\src\main\resources\dlls\HelloWorld.dll
S:\Accessibility\tools\src\test\java\com\accessibility\HelloWorld.class

My code contained the following line

System.load(HelloWorld.class.getResource("/dlls/HelloWorld.dll").getPath());

First, I had to move to the classpath directory

cd /D "S:\Accessibility\tools\src\test\java"

Next, I had to change the classpath to point to the current directory so that my class would be loaded and I had to change the classpath to point to he resources directory so my dll would be loaded.

set classpath=%classpath%;.;..\..\..\src\main\resources; 

Then, I had to run java using the classname.

java com.accessibility.HelloWorld 

Make sure that the sorting is not to complicated for the end user. I always thought sorting on group and sub group is a little bit complicated to understand. If its a technical end user it might be OK.

It works for me:

File imgFile = new  File("/sdcard/Images/test_image.jpg");
if(imgFile.exists()){
    Bitmap myBitmap = BitmapFactory.decodeFile(imgFile.getAbsolutePath());
    //Drawable d = new BitmapDrawable(getResources(), myBitmap);
    ImageView myImage = (ImageView) findViewById(R.id.imageviewTest);
    myImage.setImageBitmap(myBitmap);

}

Edit:

If above hard-coded sdcard directory is not working in your case, you can fetch the sdcard path:

String sdcardPath = Environment.getExternalStorageDirectory().toString();
File imgFile = new  File(sdcardPath);

Set is used for setting object references, as opposed to assigning a value.

To the best of my memory, a physical address is an explicit, set in stone address in memory, while a logical address consists of a base pointer and offset.

The reason is as you have basically specified. It allows for not only the segmentation of programs and processes into threads and data, but also for the dynamic loading of such programs, and the allowance for at least pseudo-parallelism, without any actual interlacing of instructions in memory needing to take place.

You will have the same object two times in your array, because object values are passed by reference. You have to create a new object like this

myElement.id = 244;
myElement.value = 3556;
myArray[0] = $.extend({}, myElement); //for shallow copy or
myArray[0] = $.extend(true, {}, myElement); // for deep copy

or

myArray.push({ id: 24, value: 246 });

check the official example. X,Y and Z are indeed 2d arrays, numpy.meshgrid() is a simple way to get 2d x,y mesh out of 1d x and y values.

http://matplotlib.sourceforge.net/mpl_examples/mplot3d/surface3d_demo.py

here's pythonic way to convert your 3-tuples to 3 1d arrays.

data = [(1,2,3), (10,20,30), (11, 22, 33), (110, 220, 330)]
X,Y,Z = zip(*data)
In [7]: X
Out[7]: (1, 10, 11, 110)
In [8]: Y
Out[8]: (2, 20, 22, 220)
In [9]: Z
Out[9]: (3, 30, 33, 330)

Here's mtaplotlib delaunay triangulation (interpolation), it converts 1d x,y,z into something compliant (?):

You can use higher-order functions too to do the operation. See this answer

obj= Model.objects.filter(testfield=12).order_by('-id')[0]

Save and load a dictionary. You will have arbitrary keys, values and arbitrary number of key, values pairs.

since HashMap implements Serializable interface, you can simply use ObjectOutputStream class to write whole Map to file, and read it again using ObjectInputStream class

below simple code that explain usage of ObjectOutStream and ObjectInputStream

import java.util.*;
import java.io.*;
public class A{

    HashMap<String,String> hm;
    public A() {
        hm=new HashMap<String,String>();

        hm.put("1","A");
        hm.put("2","B");
        hm.put("3","C");

        method1(hm);

    }

public void method1(HashMap<String,String> map) {
    //write to file : "fileone"
    try {
        File fileOne=new File("fileone");
        FileOutputStream fos=new FileOutputStream(fileOne);
        ObjectOutputStream oos=new ObjectOutputStream(fos);

        oos.writeObject(map);
        oos.flush();
        oos.close();
        fos.close();
    } catch(Exception e) {}

    //read from file 
    try {
        File toRead=new File("fileone");
        FileInputStream fis=new FileInputStream(toRead);
        ObjectInputStream ois=new ObjectInputStream(fis);

        HashMap<String,String> mapInFile=(HashMap<String,String>)ois.readObject();

        ois.close();
        fis.close();
        //print All data in MAP
        for(Map.Entry<String,String> m :mapInFile.entrySet()){
            System.out.println(m.getKey()+" : "+m.getValue());
        }
    } catch(Exception e) {}
  }

public static void main(String args[]) {
        new A();
}

}

or if you want to write data as text to file you can simply iterate through Map and write key and value line by line, and read it again line by line and add to HashMap

import java.util.*;
import java.io.*;
public class A{

    HashMap<String,String> hm;
    public A(){
        hm=new HashMap<String,String>();

        hm.put("1","A");
        hm.put("2","B");
        hm.put("3","C");

        method2(hm);

    }

public void method2(HashMap<String,String> map) {
    //write to file : "fileone"
    try {
        File fileTwo=new File("filetwo.txt");
        FileOutputStream fos=new FileOutputStream(fileTwo);
        PrintWriter pw=new PrintWriter(fos);

        for(Map.Entry<String,String> m :map.entrySet()){
            pw.println(m.getKey()+"="+m.getValue());
        }

        pw.flush();
        pw.close();
        fos.close();
    } catch(Exception e) {}

    //read from file 
    try {
        File toRead=new File("filetwo.txt");
        FileInputStream fis=new FileInputStream(toRead);

        Scanner sc=new Scanner(fis);

        HashMap<String,String> mapInFile=new HashMap<String,String>();

        //read data from file line by line:
        String currentLine;
        while(sc.hasNextLine()) {
            currentLine=sc.nextLine();
            //now tokenize the currentLine:
            StringTokenizer st=new StringTokenizer(currentLine,"=",false);
            //put tokens ot currentLine in map
            mapInFile.put(st.nextToken(),st.nextToken());
        }
        fis.close();

        //print All data in MAP
        for(Map.Entry<String,String> m :mapInFile.entrySet()) {
            System.out.println(m.getKey()+" : "+m.getValue());
        }
    }catch(Exception e) {}
  }

public static void main(String args[]) {
        new A();
}

}

NOTE: above code may not be the fastest way to doing this task, but i want to show some application of classes

See ObjectOutputStream , ObjectInputStream, HashMap, Serializable, StringTokenizer

<style type="text/css" media="print">
.landscape { 
    width: 100%; 
    height: 100%; 
    margin: 0% 0% 0% 0%; filter: progid:DXImageTransform.Microsoft.BasicImage(Rotation=1); 
} 
</style>

If you want this style to be applied to a table then create one div tag with this style class and add the table tag within this div tag and close the div tag at the end.

This table will only print in landscape and all other pages will print in portrait mode only. But the problem is if the table size is more than the page width then we may loose some of the rows and sometimes headers also are missed. Be careful.

Have a good day.

Thank you, Naveen Mettapally.

After many struggles and to achive a general, flexible and more readable solution, in my case I ended up saving the ORs results into ENV variables and doing the ANDs of those variables.

# RESULT_ONE = A OR B
RewriteRule ^ - [E=RESULT_ONE:False]
RewriteCond ...A... [OR]
RewriteCond ...B...
RewriteRule ^ - [E=RESULT_ONE:True]

# RESULT_TWO = C OR D
RewriteRule ^ - [E=RESULT_TWO:False]
RewriteCond ...C... [OR]
RewriteCond ...D...
RewriteRule ^ - [E=RESULT_TWO:True]

# if ( RESULT_ONE AND RESULT_TWO ) then ( RewriteRule ...something... )
RewriteCond %{ENV:RESULT_ONE} =True
RewriteCond %{ENV:RESULT_TWO} =True
RewriteRule ...something...

Requirements:

• Apache mod_env enabled

django is smart enough. Actually we don't need to define oneToMany field. It will be automatically generated by django for you :-). We only need to define foreignKey in related table. In other words, we only need to define ManyToOne relation by using foreignKey.

class Car(models.Model):
    // wheels = models.oneToMany() to get wheels of this car [**it is not required to define**].


class Wheel(models.Model):
    car = models.ForeignKey(Car, on_delete=models.CASCADE)  

if we want to get the list of wheels of particular car. we will use python's auto generated object wheel_set. For car c you will use c.wheel_set.all()

If anybody is interested in using regex with CLR here is a solution. The function below (C# .net 4.5) returns a 1 if the pattern is matched and a 0 if the pattern is not matched. I use it to tag lines in sub queries. The SQLfunction attribute tells sql server that this method is the actual UDF that SQL server will use. Save the file as a dll in a place where you can access it from management studio.

// default using statements above
using System.Data.SqlClient;
using System.Data.SqlTypes;
using Microsoft.SqlServer.Server;
using System.Text.RegularExpressions;

namespace CLR_Functions
{   
    public class myFunctions
    {
        [SqlFunction]
        public static SqlInt16 RegexContain(SqlString text, SqlString pattern)
        {            
            SqlInt16 returnVal = 0;
            try
            {
                string myText = text.ToString();
                string myPattern = pattern.ToString();
                MatchCollection mc = Regex.Matches(myText, myPattern);
                if (mc.Count > 0)
                {
                    returnVal = 1;
                }
            }
            catch
            {
                returnVal = 0;
            }

            return returnVal;
        }
    }
}

In management studio import the dll file via programability -- assemblies -- new assembly

Then run this query:

CREATE FUNCTION RegexContain(@text NVARCHAR(50), @pattern NVARCHAR(50))
RETURNS smallint 
AS
EXTERNAL NAME CLR_Functions.[CLR_Functions.myFunctions].RegexContain

Then you should have complete access to the function via the database you stored the assembly in.

Then use in queries like so:

SELECT * 
FROM 
(
    SELECT
        DailyLog.Date,
        DailyLog.Researcher,
        DailyLog.team,
        DailyLog.field,
        DailyLog.EntityID,
        DailyLog.[From],
        DailyLog.[To],
        dbo.RegexContain(Researcher, '[\p{L}\s]+') as 'is null values'
    FROM [DailyOps].[dbo].[DailyLog]
) AS a
WHERE a.[is null values] = 0

private - encapsulations in class/scope/struct ect'.

internal - encapsulation in assemblies.

If you are using torch you can do:

import torch.multiprocessing as mp

mp.cpu_count()

Before the days of jQuery you would use:

   document.getElementById('findmebyid');

If this one line will save you an entire jQuery library, it might be worth while using it instead.

For those concerned about performance: Beginning your selector with an ID is always best as it uses native function document.getElementById.

// Fast:
$( "#container div.robotarm" );

// Super-fast:
$( "#container" ).find( "div.robotarm" );

I'm using Ubuntu 18.04 LTS. Most of the time, when I change my java version, I also want to use the same javac version.
I use update-alternatives this way, using a java_home alternative instead :

Installation

Install every java version in /opt/java/<version>, for example

~$ ll /opt/java/

Configure alternatives

~$ sudo update-alternatives --install /opt/java/current java_home /opt/java/jdk-11.0.2/ 100
~$ sudo update-alternatives --install /opt/java/current java_home /opt/java/jdk1.8.0_201 200

Declare JAVA_HOME (In this case, I use a global initialization script for this)

~$ sudo sh -c 'echo export JAVA_HOME=\"/opt/java/current\" >> environment.sh'

Log Out or restart Ubuntu (this will reload /etc/profile.d/environment.sh)

Usage

Change java version

Choose the version you want to use

~$ sudo update-alternatives --config java_home

There are 2 choices for the alternative java_home (providing /opt/java/current).

  Selection    Path                    Priority   Status
------------------------------------------------------------
  0            /opt/java/jdk-11.0.2     200       auto mode
  1            /opt/java/jdk-11.0.2     200       manual mode
* 2            /opt/java/jdk1.8.0_201   100       manual mode

Press <enter> to keep the current choice[*], or type selection number: 

Check version

~$ java -version
openjdk version "11.0.2" 2019-01-15
OpenJDK Runtime Environment 18.9 (build 11.0.2+9)
OpenJDK 64-Bit Server VM 18.9 (build 11.0.2+9, mixed mode)

~$ javac -version
javac 11.0.2

Tip

Add the following line to ~/.bash_aliases file :

alias change-java-version="sudo update-alternatives --config java_home && java -version && javac -version"

Now use the change-java-version command to change java version

Make sure you have the right selector, and then wait until the page is ready and that the element exists until you run the function.

$(function(){
    $('#searchBar').val('hi')
});

As Derek points out, the ID is wrong as well.

Change to $('#main_search')

You can use the --recursive flag when cloning a repository. This parameter forces git to clone all defined submodules in the repository.

git clone --recursive [email protected]:your_repo.git

After cloning, sometimes submodules branches may be changed, so run this command after it:

git submodule foreach "git checkout master"

Use one of the functions from pkgutil, for example:

from pkgutil import iter_modules

def module_exists(module_name):
    return module_name in (name for loader, name, ispkg in iter_modules())

INSTALLING MULTIPLE KERNELS TO A SINGLE VIRTUAL ENVIRONMENT (VENV)

Most (if not all) of these answers assume you are happy to install packages globally. This answer is for you if you:

• use a *NIX machine
• don't like installing packages globally
• don't want to use anaconda <-> you're happy to run the jupyter server from the command line
• want to have a sense of what/where the kernel installation 'is'.

(Note: this answer adds a python2 kernel to a python3-jupyter install, but it's conceptually easy to swap things around.)

1. Prerequisites

   1. You're in the dir from which you'll run the jupyter server and save files
   2. python2 is installed on your machine
   3. python3 is installed on your machine
   4. virtualenv is installed on your machine

2. Create a python3 venv and install jupyter

   1. Create a fresh python3 venv: python3 -m venv .venv
   2. Activate the venv: . .venv/bin/activate
   3. Install jupyterlab: pip install jupyterlab. This will create locally all the essential infrastructure for running notebooks.
   4. Note: by installing jupyterlab here, you also generate default 'kernel specs' (see below) in $PWD/.venv/share/jupyter/kernels/python3/. If you want to install and run jupyter elsewhere, and only use this venv for organizing all your kernels, then you only need: pip install ipykernel
   5. You can now run jupyter lab with jupyter lab (and go to your browser to the url displayed in the console). So far, you'll only see one kernel option called 'Python 3'. (This name is determined by the display_name entry in your kernel.json file.)

3. Add a python2 kernel

   1. Quit jupyter (or start another shell in the same dir): ctrl-c
   2. Deactivate your python3 venv: deactivate
   3. Create a new venv in the same dir for python2: virtualenv -p python2 .venv2
   4. Activate your python2 venv: . .venv2/bin/activate
   5. Install the ipykernel module: pip install ipykernel. This will also generate default kernel specs for this python2 venv in .venv2/share/jupyter/kernels/python2
   6. Export these kernel specs to your python3 venv: python -m ipykernel install --prefix=$PWD/.venv. This basically just copies the dir $PWD/.venv2/share/jupyter/kernels/python2 to $PWD/.venv/share/jupyter/kernels/
   7. Switch back to your python3 venv and/or rerun/re-examine your jupyter server: deactivate; . .venv/bin/activate; jupyter lab. If all went well, you'll see a Python 2 option in your list of kernels. You can test that they're running real python2/python3 interpreters by their handling of a simple print 'Hellow world' vs print('Hellow world') command.
   8. Note: you don't need to create a separate venv for python2 if you're happy to install ipykernel and reference the python2-kernel specs from a global space, but I prefer having all of my dependencies in one local dir

TL;DR

4. Optionally install an R kernel. This is instructive to develop a sense of what a kernel 'is'.
   1. From the same dir, install the R IRkernel package: R -e "install.packages('IRkernel',repos='https://cran.mtu.edu/')". (This will install to your standard R-packages location; for home-brewed-installed R on a Mac, this will look like /usr/local/Cellar/r/3.5.2_2/lib/R/library/IRkernel.)
   2. The IRkernel package comes with a function to export its kernel specs, so run: R -e "IRkernel::installspec(prefix=paste(getwd(),'/.venv',sep=''))". If you now look in $PWD/.venv/share/jupyter/kernels/ you'll find an ir directory with kernel.json file that looks something like this:

{
  "argv": ["/usr/local/Cellar/r/3.5.2_2/lib/R/bin/R", "--slave", "-e", "IRkernel::main()", "--args", "{connection_file}"],
  "display_name": "R",
  "language": "R"
}

In summary, a kernel just 'is' an invocation of a language-specific executable from a kernel.json file that jupyter looks for in the .../share/jupyter/kernels dir and lists in its interface; in this case, R is being called to run the function IRkernel::main(), which will send messages back and forth to the Jupiter server. Likewise, the python2 kernel just 'is' an invocation of the python2 interpreter with module ipykernel_launcher as seen in .venv/share/jupyter/kernels/python2/kernel.json, etc.

Here is a script if you want to run all of these instructions in one fell swoop.

How to convert a number to a string in C++03

1. Do not use the itoa or itof functions because they are non-standard and therefore not portable.
   

2. Use string streams
   

    #include <sstream>  //include this to use string streams
    #include <string> 
   
   int main()
   {    
       int number = 1234;
   
       std::ostringstream ostr; //output string stream
       ostr << number; //use the string stream just like cout,
       //except the stream prints not to stdout but to a string.
   
       std::string theNumberString = ostr.str(); //the str() function of the stream 
       //returns the string.
   
       //now  theNumberString is "1234"  
   }
   

   Note that you can use string streams also to convert floating-point numbers to string, and also to format the string as you wish, just like with cout

   std::ostringstream ostr;
   float f = 1.2;
   int i = 3;
   ostr << f << " + " i << " = " << f + i;   
   std::string s = ostr.str();
   //now s is "1.2 + 3 = 4.2" 
   

   You can use stream manipulators, such as std::endl, std::hex and functions std::setw(), std::setprecision() etc. with string streams in exactly the same manner as with cout

   Do not confuse std::ostringstream with std::ostrstream. The latter is deprecated

3. Use boost lexical cast. If you are not familiar with boost, it is a good idea to start with a small library like this lexical_cast. To download and install boost and its documentation go here. Although boost isn't in C++ standard many libraries of boost get standardized eventually and boost is widely considered of the best C++ libraries.

   Lexical cast uses streams underneath, so basically this option is the same as the previous one, just less verbose.

   #include <boost/lexical_cast.hpp>
   #include <string>
   
   int main()
   {
      float f = 1.2;
      int i = 42;
      std::string sf = boost::lexical_cast<std::string>(f); //sf is "1.2"
      std::string si = boost::lexical_cast<std::string>(i); //sf is "42"
   }
   

How to convert a string to a number in C++03

1. The most lightweight option, inherited from C, is the functions atoi (for integers (alphabetical to integer)) and atof (for floating-point values (alphabetical to float)). These functions take a C-style string as an argument (const char *) and therefore their usage may be considered a not exactly good C++ practice. cplusplus.com has easy-to-understand documentation on both atoi and atof including how they behave in case of bad input. However the link contains an error in that according to the standard if the input number is too large to fit in the target type, the behavior is undefined.

   #include <cstdlib> //the standard C library header
   #include <string>
   int main()
   {
       std::string si = "12";
       std::string sf = "1.2";
       int i = atoi(si.c_str()); //the c_str() function "converts" 
       double f = atof(sf.c_str()); //std::string to const char*
   }
   

2. Use string streams (this time input string stream, istringstream). Again, istringstream is used just like cin. Again, do not confuse istringstream with istrstream. The latter is deprecated.

   #include <sstream>
   #include <string>
   int main()
   {
      std::string inputString = "1234 12.3 44";
      std::istringstream istr(inputString);
      int i1, i2;
      float f;
      istr >> i1 >> f >> i2;
      //i1 is 1234, f is 12.3, i2 is 44  
   }
   

3. Use boost lexical cast.

   #include <boost/lexical_cast.hpp>
   #include <string>
   
   int main()
   {
      std::string sf = "42.2"; 
      std::string si = "42";
      float f = boost::lexical_cast<float>(sf); //f is 42.2
      int i = boost::lexical_cast<int>(si);  //i is 42
   }       
   

   In case of a bad input, lexical_cast throws an exception of type boost::bad_lexical_cast

Something that I think should be commented here that worked for me:

Use :last-child multiple times in the places needed so that it always gets the last of the last.

Take this for example:

.page.one .page-container .comment:last-child {_x000D_
  color: red;_x000D_
}_x000D_
.page.two .page-container:last-child .comment:last-child {_x000D_
  color: blue;_x000D_
}

<p> When you use .comment:last-child </p>_x000D_
<p> you only get the last comment in both parents </p>_x000D_
_x000D_
<div class="page one">_x000D_
  <div class="page-container">_x000D_
    <p class="comment"> Something </p>_x000D_
    <p class="comment"> Something </p>_x000D_
  </div>_x000D_
_x000D_
  <div class="page-container">_x000D_
    <p class="comment"> Something </p>_x000D_
    <p class="comment"> Something </p>_x000D_
  </div>_x000D_
</div>_x000D_
_x000D_
<p> When you use .page-container:last-child .comment:last-child </p>_x000D_
<p> you get the last page-container's, last comment </p>_x000D_
_x000D_
<div class="page two">_x000D_
  <div class="page-container">_x000D_
    <p class="comment"> Something </p>_x000D_
    <p class="comment"> Something </p>_x000D_
  </div>_x000D_
_x000D_
  <div class="page-container">_x000D_
    <p class="comment"> Something </p>_x000D_
    <p class="comment"> Something </p>_x000D_
  </div>_x000D_
</div>

This is old topic but on my last test on one my API, cURL is faster and more stable. Sometimes file_get_contents on larger request need over 5 seconds when cURL need only from 1.4 to 1.9 seconds what is double faster.

I need to add one note on this that I just send GET and recive JSON content. If you setup cURL properly, you will have a great response. Just "tell" to cURL what you need to send and what you need to recive and that's it.

On your exampe I would like to do this setup:

$ch =  curl_init('http://api.bitly.com/v3/shorten?login=user&apiKey=key&longUrl=url');
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
    curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 5);
    curl_setopt($ch, CURLOPT_TIMEOUT, 3);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array('Accept: application/json'));
$result = curl_exec($ch);

This request will return data in 0.10 second max

You can also get this error by prematurely taking PyCharm's advice to annotate a method @staticmethod. Remove the annotation.

As all the other answers say; it can be almost anything but is usually "JQuery".

However, in ES6 it is a string interpolation operator in a template "literal" eg.

var s = "new" ; // you can put whatever you think appropriate here.
var s2 = `There are so many ${s} ideas these days !!` ; //back-ticks not quotes
console.log(s2) ;

result:

There are so many new ideas these days !!

Here's a module for calculating SHA1 hashes that is usable for Excel formulas eg. '=SHA1HASH("test")'. To use it, make a new module called 'module_sha1' and copy and paste it all in. This is based on some VBA code from http://vb.wikia.com/wiki/SHA-1.bas, with changes to support passing it a string, and executable from formulas in Excel cells.

In your component -

Make sure to initialize the formControl name country with a value.

For instance: Assuming that your form group name is myForm and _fb is FormBuilder instance then,

....
this.myForm = this._fb.group({
  country:[this.default]
})

and also try replacing [value] with [ngValue].

EDIT 1: If you are unable to initialize the value when declaring then set the value when you have the value like this.

this.myForm.controls.country.controls.setValue(this.country) 

For >= 2nd row values insert into table-

$file = fopen($filename, "r");
//$sql_data = "SELECT * FROM prod_list_1 ";

$count = 0;                                         // add this line
while (($emapData = fgetcsv($file, 10000, ",")) !== FALSE)
{
    //print_r($emapData);
    //exit();
    $count++;                                      // add this line

How about this one?

import signal
signal.pause()

This will let your program sleep until it receives a signal from some other process (or itself, in another thread), letting it know it is time to do something.

Date: Dec 10, 1997 3:36:19 pm

I have an unusual request for the Perl developers (those that develop the Perl language). I hope this (perl5-porters) is the right list. I am cc'ing the Python string-sig because it is the origin of most of the work I'm discussing here.

You are probably aware of Python. I am Python's creator; I am planning to release a next "major" version, Python 1.5, by the end of this year. I hope that Python and Perl can co-exist in years to come; cross-pollination can be good for both languages. (I believe Larry had a good look at Python when he added objects to Perl 5; O'Reilly publishes books about both languages.)

As you may know, Python 1.5 adds a new regular expression module that more closely matches Perl's syntax. We've tried to be as close to the Perl syntax as possible within Python's syntax. However, the regex syntax has some Python-specific extensions, which all begin with (?P . Currently there are two of them:

(?P<foo>...) Similar to regular grouping parentheses, but the text
matched by the group is accessible after the match has been performed, via the symbolic group name "foo".

(?P=foo) Matches the same string as that matched by the group named "foo". Equivalent to \1, \2, etc. except that the group is referred
to by name, not number.

I hope that this Python-specific extension won't conflict with any future Perl extensions to the Perl regex syntax. If you have plans to use (?P, please let us know as soon as possible so we can resolve the conflict. Otherwise, it would be nice if the (?P syntax could be permanently reserved for Python-specific syntax extensions. (Is there some kind of registry of extensions?)

to which Larry Wall replied:

[...] There's no registry as of now--yours is the first request from outside perl5-porters, so it's a pretty low-bandwidth activity. (Sorry it was even lower last week--I was off in New York at Internet World.)

Anyway, as far as I'm concerned, you may certainly have 'P' with my blessing. (Obviously Perl doesn't need the 'P' at this point. :-) [...]

So I don't know what the original choice of P was motivated by -- pattern? placeholder? penguins? -- but you can understand why I've always associated it with Python. Which considering that (1) I don't like regular expressions and avoid them wherever possible, and (2) this thread happened fifteen years ago, is kind of odd.

I believe that function __construct () {...} is a piece of code that can be reused again and again in substitution for TheActualFunctionName () {...}. If you change the CLASS Name you do not have to change within the code because the generic __construct refers always to the actual class name...whatever it is. You code less...or?

To be perfectly precise, Darwin is enough. No need to import the whole Cocoa framework.

import Darwin

Of course, if you need elements from Cocoa or Foundation or other higher level frameworks, you can import them instead

At the time when this question was asked there wasn't another function in Pandas to test equality, but it has been added a while ago: pandas.equals

You use it like this:

df1.equals(df2)

Some differenes to == are:

• You don't get the error described in the question
• It returns a simple boolean.
• NaN values in the same location are considered equal
• 2 DataFrames need to have the same dtype to be considered equal, see this stackoverflow question

Note that callback syntax is deprecated:

Deprecation Notice

The jqXHR.success(), jqXHR.error(), and jqXHR.complete() callback methods introduced in jQuery 1.5 are deprecated as of jQuery 1.8. To prepare your code for their eventual removal, use jqXHR.done(), jqXHR.fail(), and jqXHR.always() instead.

Here a modernized solution using the promise interface

$.ajax({url: "...", cache: false}).done(function( data ) {
    // data contains result
}).fail(function(err){
    // error
});

Using the child selector, I've taken Fadi's incredible answer above and boiled it down to just one CSS rule that I can apply. Now all I have to do is add the contentCentered class name to elements I want to center:

.contentCentered {_x000D_
  text-align: center;_x000D_
}_x000D_
_x000D_
.contentCentered::before {_x000D_
  content: '';_x000D_
  display: inline-block;_x000D_
  height: 100%; _x000D_
  vertical-align: middle;_x000D_
  margin-right: -.25em; /* Adjusts for spacing */_x000D_
}_x000D_
_x000D_
.contentCentered > * {_x000D_
  display: inline-block;_x000D_
  vertical-align: middle;_x000D_
}

<div class="contentCentered">_x000D_
  <div>_x000D_
    <h1>Some text</h1>_x000D_
    <p>But he stole up to us again, and suddenly clapping his hand on my_x000D_
      shoulder, said&mdash;"Did ye see anything looking like men going_x000D_
      towards that ship a while ago?"</p>_x000D_
  </div>_x000D_
</div>

had a same problem few minutes ago and just content:none; did not do work but adding content:none !important; and display:none !important; worked for me

Note that you can also determine in pure js in what browser you script is beeing executed through : window.navigator.userAgent

However, that's not a recommended way as it's configurable in the browser settings. More info available there: https://developer.mozilla.org/fr/docs/DOM/window.navigator.userAgent

As a rule of thumb, the best place to put <script> tags is the bottom of the page, just before </body> tag. Something like this:

<html>
    <head>
        <title>My awesome page</title>

        <!-- CSS -->
        <link rel="stylesheet" type="text/css" href="...">
        <link rel="stylesheet" type="text/css" href="...">
        <link rel="stylesheet" type="text/css" href="...">
        <link rel="stylesheet" type="text/css" href="...">

    </head>
    <body>
        <!-- Content content content -->

        <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
        <script type="text/javascript" src="..."></script>
        <script type="text/javascript" src="..."></script>
        <script type="text/javascript" src="..."></script>
    </body>
</html>

Why?

The problem caused by scripts is that they block parallel downloads. The HTTP/1.1 specification suggests that browsers download no more than two components in parallel per hostname. If you serve your images from multiple hostnames, you can get more than two downloads to occur in parallel. While a script is downloading, however, the browser won't start any other downloads, even on different hostnames. More...

CSS

A little bit off-topic, but... Put stylesheets at the top.

While researching performance at Yahoo!, we discovered that moving stylesheets to the document HEAD makes pages appear to be loading faster. This is because putting stylesheets in the HEAD allows the page to render progressively. More...

Yahoo have released a really cool guide that lists best practices to speed up a website. Definitely worth reading: https://developer.yahoo.com/performance/rules.html

This is an error that you see when your emulator has the "Use host GPU" setting checked. If you uncheck it then the error goes away. Of course, then your emulator is not as responsive anymore.

I just worked through this issue on my service. Here is the error I was receiving:

Service 'EmailSender.Wcf.EmailService' has zero application (non-infrastructure) endpoints. This might be because no configuration file was found for your application, or because no service element matching the service name could be found in the configuration file, or because no endpoints were defined in the service element.

Here are the two steps I used to fix it:

1. Use the correct fully-qualified class name:

   <service behaviorConfiguration="DefaultBehavior" name="EmailSender.Wcf.EmailService">
   

2. Enable an endpoint with mexHttpBinding, and most importantly, use the IMetadataExchange contract:

   <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
   

I know this is an old question but I could not find a solution to this problem after some research, so I am sharing what worked for me.

I have written this C# code for one of my projects. It can bypass the scan virus warning programmatically. The code can probably be converted to Java.

And here's how you can use it:

// NOTE: FileDownloader is IDisposable!
FileDownloader fileDownloader = new FileDownloader();

// This callback is triggered for DownloadFileAsync only
fileDownloader.DownloadProgressChanged += ( sender, e ) => Console.WriteLine( "Progress changed " + e.BytesReceived + " " + e.TotalBytesToReceive );
// This callback is triggered for both DownloadFile and DownloadFileAsync
fileDownloader.DownloadFileCompleted += ( sender, e ) => Console.WriteLine( "Download completed" );

fileDownloader.DownloadFileAsync( "https://INSERT_DOWNLOAD_LINK_HERE", @"C:\downloadedFile.txt" );

Try this in your css:

#ntext{
 color: #000000;
  }

Then the following in all your navigation bar list codes:

<li><a href="#" id="ntext"><span class="glyphicon glyphicon-user"></span> About</a></li>

I have just read some parts of his Crockfords book "Javascript: The Good Parts". I get the feeling that he considers everything that ever has bitten him as harmful:

About switch fall through:

I never allow switch cases to fall through to the next case. I once found a bug in my code caused by an unintended fall through immediately after having made a vigorous speech about why fall through was sometimes useful. (page 97, ISBN 978-0-596-51774-8)

About ++ and --

The ++ (increment) and -- (decrement) operators have been known to contribute to bad code by encouraging exessive trickiness. They are second only to faulty architecture in enabling viruses and other security menaces. (page 122)

About new:

If you forget to include the new prefix when calling a constructor function, then this will not be bound to the new object. Sadly, this will be bound to the global object, so instead of augmenting your new object, you will be clobbering global variables. That is really bad. There is no compile warning, and there is no runtime warning. (page 49)

There are more, but I hope you get the picture.

My answer to your question: No, it's not harmful. but if you forget to use it when you should you could have some problems. If you are developing in a good environment you notice that.

Update

About a year after this answer was written the 5th edition of ECMAScript was released, with support for strict mode. In strict mode, this is no longer bound to the global object but to undefined.

1.If I have something like Foo o = new Foo(); inside the method, does that mean that each time the timer ticks, I'm creating a new object and a new reference to that object?

Yes.

2.If I have string foo = null and then I just put something temporal in foo, is it the same as above?

If you are asking if the behavior is the same then yes.

3.Does the garbage collector ever delete the object and the reference or objects are continually created and stay in memory?

The memory used by those objects is most certainly collected after the references are deemed to be unused.

4.If I just declare Foo o; and not point it to any instance, isn't that disposed when the method ends?

No, since no object was created then there is no object to collect (dispose is not the right word).

5.If I want to ensure that everything is deleted, what is the best way of doing it

If the object's class implements IDisposable then you certainly want to greedily call Dispose as soon as possible. The using keyword makes this easier because it calls Dispose automatically in an exception-safe way.

Other than that there really is nothing else you need to do except to stop using the object. If the reference is a local variable then when it goes out of scope it will be eligible for collection.¹ If it is a class level variable then you may need to assign null to it to make it eligible before the containing class is eligible.

¹This is technically incorrect (or at least a little misleading). An object can be eligible for collection long before it goes out of scope. The CLR is optimized to collect memory when it detects that a reference is no longer used. In extreme cases the CLR can collect an object even while one of its methods is still executing!

Update:

Here is an example that demonstrates that the GC will collect objects even though they may still be in-scope. You have to compile a Release build and run this outside of the debugger.

static void Main(string[] args)
{
    Console.WriteLine("Before allocation");
    var bo = new BigObject();
    Console.WriteLine("After allocation");
    bo.SomeMethod();
    Console.ReadLine();
    // The object is technically in-scope here which means it must still be rooted.
}

private class BigObject
{
    private byte[] LotsOfMemory = new byte[Int32.MaxValue / 4];

    public BigObject()

On my machine the finalizer is run while SomeMethod is still executing!

You can use the jQuery find method

 $('select').change(function () {
     var optionSelected = $(this).find("option:selected");
     var valueSelected  = optionSelected.val();
     var textSelected   = optionSelected.text();
 });

The above solution works perfectly but I choose to add the following code for them willing to get the clicked option. It allows you get the selected option even when this select value has not changed. (Tested with Mozilla only)

    $('select').find('option').click(function () {
     var optionSelected = $(this);
     var valueSelected  = optionSelected.val();
     var textSelected   = optionSelected.text();
   });

array1.NonIntersect(array2);

Nonintersect such operator is not present in Linq you should do

except -> union -> except

a.except(b).union(b.Except(a));

SELECT id, COUNT(id) FROM table1 GROUP BY id HAVING COUNT(id)>1;

I think this will work properly to search repeated values in a particular column.

@Egidius, when creating an XMLHttpRequest, you should use

var xhr = new XMLHttpRequest({mozSystem: true});

What is mozSystem?

mozSystem Boolean: Setting this flag to true allows making cross-site connections without requiring the server to opt-in using CORS. Requires setting mozAnon: true, i.e. this can't be combined with sending cookies or other user credentials. This only works in privileged (reviewed) apps; it does not work on arbitrary webpages loaded in Firefox.

Changes to your Manifest

On your manifest, do not forget to include this line on your permissions:

"permissions": {
       "systemXHR" : {},
}

Just add the <mat-icon> inside mat-button or mat-raised-button. See the example below. Note that I am using material icon instead of your svg for demo purpose:

<button mat-button>
    <mat-icon>mic</mat-icon>
    Start Recording
</button>

OR

<button mat-raised-button color="accent">
    <mat-icon>mic</mat-icon>
    Start Recording
</button>

Here is a link to stackblitz demo.

yes there is : len(data)-1.

For the first element it´s : 0

SQL Server / MS Access Syntax:

SELECT TOP 1 * FROM table_name ORDER BY RAND()

MySQL Syntax:

SELECT * FROM table_name ORDER BY RAND() LIMIT 1

You can use this commands:

docker exec -it yournamecontainer psql -U postgres -c "CREATE DATABASE mydatabase ENCODING 'LATIN1' TEMPLATE template0 LC_COLLATE 'C' LC_CTYPE 'C';"

docker exec -it yournamecontainer psql -U postgres -c "GRANT ALL PRIVILEGES ON DATABASE postgres TO postgres;"

If you need a User Interface and if you want to use PDO

Here's a simple solution

<form method="post" enctype="multipart/form-data">
    <input type="text" name="db" placeholder="Databasename" />
    <input type="file" name="file">
    <input type="submit" name="submit" value="submit">
</form>

<?php

if(isset($_POST['submit'])){
    $query = file_get_contents($_FILES["file"]["name"]);
    $dbname = $_POST['db'];
    $con = new PDO("mysql:host=localhost;dbname=$dbname","root","");
    $stmt = $con->prepare($query);
    if($stmt->execute()){
        echo "Successfully imported to the $dbname.";
    }
}
?>

Definitely working on my end. Worth a try.

OpenCV has region of interest functions which you may find useful. If you are using the cv::Mat then you could use something like the following.

// You mention that you start with a CVMat* imagesource
CVMat * imagesource;

// Transform it into the C++ cv::Mat format
cv::Mat image(imagesource); 

// Setup a rectangle to define your region of interest
cv::Rect myROI(10, 10, 100, 100);

// Crop the full image to that image contained by the rectangle myROI
// Note that this doesn't copy the data
cv::Mat croppedImage = image(myROI);

Documentation for extracting sub image

We can also use ReentrantLock to achieve the synchronization for static variables.

public class Test {

    private static int count = 0;
    private static final ReentrantLock reentrantLock = new ReentrantLock(); 
    public void foo() {  
        reentrantLock.lock();
        count = count + 1;
        reentrantLock.unlock();
    }  
}

You can use this, just think Job is the name of the model to which you are adding index cader_id:

class AddCaderIdToJob < ActiveRecord::Migration[5.2]
  def change
    change_table :jobs do |t|
      t.integer :cader_id
      t.index :cader_id
    end
  end
end

If you want to list them all in a nice list but without using the cruddy non human friendly name, you can do this...

object.errors.each do |attr,message|
  puts "<li>"+message+"</li>"
end

I restore my files using the SHA id, What i do is git checkout <sha hash id> <file name>

Some versions of Ruby on Rails support to up/down method to migration and if you have up/down method in your migration, then:

def up
    rename_column :table_name, :column_old_name, :column_new_name
end

def down
    rename_column :table_name, :column_new_name, :column_old_name
end

If you have the change method in your migration, then:

def change
    rename_column :table_name, :column_old_name, :column_new_name
end

For more information you can move: Ruby on Rails - Migrations or Active Record Migrations.

The following worked for me:

1. Find all classes implementing the service(interface) which is giving the error.
2. Mark each of those classes with the @Service annotation, to indicate them as business logic classes.
3. Rebuild the project.

Such a thing probably does not exist "as-is". It doesn't really exist on Linux or other UNIX-like operating systems either though.

ncurses is only a library that helps you manage interactions with the underlying terminal environment. But it doesn't provide a terminal emulator itself.

The thing that actually displays stuff on the screen (which in your requirement is listed as "native resizable win32 windows") is usually called a Terminal Emulator. If you don't like the one that comes with Windows (you aren't alone; no person on Earth does) there are a few alternatives. There is Console, which in my experience works sometimes and appears to just wrap an underlying Windows terminal emulator (I don't know for sure, but I'm guessing, since there is a menu option to actually get access to that underlying terminal emulator, and sure enough an old crusty Windows/DOS box appears which mirrors everything in the Console window).

A better option

Another option, which may be more appealing is puttycyg. It hooks in to Putty (which, coming from a Linux background, is pretty close to what I'm used to, and free) but actually accesses an underlying cygwin instead of the Windows command interpreter (CMD.EXE). So you get all the benefits of Putty's awesome terminal emulator, as well as nice ncurses (and many other) libraries provided by cygwin. Add a couple command line arguments to the Shortcut that launches Putty (or the Batch file) and your app can be automatically launched without going through Putty's UI.

Is the result of getElementsByClassName an Array?

No

If not, what is it?

As with all DOM methods that return multiple elements, it is a NodeList, see https://developer.mozilla.org/en/DOM/document.getElementsByClassName

Because ... it (MILLISECONDS) is a static field (hiding in an enumeration, but that's what it is) ... however it is being invoked upon an instance of the given type (but see below as this isn't really true¹).

javac will "accept" that, but it should really be MyUnits.MILLISECONDS (or non-prefixed in the applicable scope).

¹ Actually, javac "rewrites" the code to the preferred form -- if m happened to be null it would not throw an NPE at run-time -- it is never actually invoked upon the instance).

Happy coding.

I'm not really seeing how the question title fits in with the rest :-) More accurate and specialized titles increase the likely hood the question/answers can benefit other programmers.

as explained here

With help from numpy one can calculate for example a linear fitting.

# plot the data itself
pylab.plot(x,y,'o')

# calc the trendline
z = numpy.polyfit(x, y, 1)
p = numpy.poly1d(z)
pylab.plot(x,p(x),"r--")
# the line equation:
print "y=%.6fx+(%.6f)"%(z[0],z[1])

Since java.sql.Date extends java.util.Date, you should be able to do

java.util.Date newDate = result.getDate("VALUEDATE");

I used Grim's technique with a little change: If someone looking for this query is because can't do a simple query due to primary key problem:

INSERT INTO table SELECT * FROM table WHERE primakey=1;

With my MySql install 5.6.26, key isn't nullable and produce an error:

#1048 - Column 'primakey' cannot be null 

So after create temporary table I change the primary key to a be nullable.

CREATE TEMPORARY TABLE tmptable_1 SELECT * FROM table WHERE primarykey = 1;
ALTER TABLE tmptable_1 MODIFY primarykey int(12) null;
UPDATE tmptable_1 SET primarykey = NULL;
INSERT INTO table SELECT * FROM tmptable_1;
DROP TEMPORARY TABLE IF EXISTS tmptable_1;

import pygame
pygame.init()
pygame.display.set_mode()
while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit(); #sys.exit() if sys is imported
        if event.type == pygame.KEYDOWN:
            if event.key == pygame.K_0:
                print("Hey, you pressed the key, '0'!")
            if event.key == pygame.K_1:
                print("Doing whatever")

In note that K_0 and K_1 aren't the only keys, to see all of them, see pygame documentation, otherwise, hit tab after typing in

pygame.

(note the . after pygame) into an idle program. Note that the K must be capital. Also note that if you don't give pygame a display size (pass no args), then it will auto-use the size of the computer screen/monitor. Happy coding!

The problem is that you are attempting to define the elements in lists to multiple lists (not multiple ints as is defined). You should be defining lists like this.

int[,] list = new int[4,4] {
 {1,2,3,4},
 {5,6,7,8},
 {1,3,2,1},
 {5,4,3,2}};

You could also do

int[] list1 = new int[4] { 1, 2, 3, 4};
int[] list2 = new int[4] { 5, 6, 7, 8};
int[] list3 = new int[4] { 1, 3, 2, 1 };
int[] list4 = new int[4] { 5, 4, 3, 2 };

int[,] lists = new int[4,4] {
 {list1[0],list1[1],list1[2],list1[3]},
 {list2[0],list2[1],list2[2],list2[3]},
 etc...};

None of the answers actually work. I've managed to find the solution myself. This is a bit hackish, but it solve the problem for me:

echo off
setlocal enableextensions
setlocal enabledelayedexpansion
set MAX_TRIES=100
set P=%PATH%
for /L %%a in (1, 1, %MAX_TRIES%) do (
  for /F "delims=;" %%g in ("!P!") do (
    echo %%g
    set P=!P:%%g;=!
    if "!P!" == "%%g" goto :eof
  )
)

Oh ! I hate batch file programming !!

Updated

Mark's solution is simpler but it won't work with path containing whitespace. This is a little-modified version of Mark's solution

echo off
setlocal enabledelayedexpansion
set NonBlankPath=%PATH: =#%
set TabbedPath=%NonBlankPath:;= %
for %%g in (%TabbedPath%) do (
  set GG=%%g
  echo !GG:#= !
)

You can increment the stack depth allowed - with this, deeper recursive calls will be possible, like this:

import sys
sys.setrecursionlimit(10000) # 10000 is an example, try with different values

... But I'd advise you to first try to optimize your code, for instance, using iteration instead of recursion.

An attribute is an instance variable.

In redux-saga, the equivalent of the above example would be

export function* loginSaga() {
  while(true) {
    const { user, pass } = yield take(LOGIN_REQUEST)
    try {
      let { data } = yield call(request.post, '/login', { user, pass });
      yield fork(loadUserData, data.uid);
      yield put({ type: LOGIN_SUCCESS, data });
    } catch(error) {
      yield put({ type: LOGIN_ERROR, error });
    }  
  }
}

export function* loadUserData(uid) {
  try {
    yield put({ type: USERDATA_REQUEST });
    let { data } = yield call(request.get, `/users/${uid}`);
    yield put({ type: USERDATA_SUCCESS, data });
  } catch(error) {
    yield put({ type: USERDATA_ERROR, error });
  }
}

The first thing to notice is that we're calling the api functions using the form yield call(func, ...args). call doesn't execute the effect, it just creates a plain object like {type: 'CALL', func, args}. The execution is delegated to the redux-saga middleware which takes care of executing the function and resuming the generator with its result.

The main advantage is that you can test the generator outside of Redux using simple equality checks

const iterator = loginSaga()

assert.deepEqual(iterator.next().value, take(LOGIN_REQUEST))

// resume the generator with some dummy action
const mockAction = {user: '...', pass: '...'}
assert.deepEqual(
  iterator.next(mockAction).value, 
  call(request.post, '/login', mockAction)
)

// simulate an error result
const mockError = 'invalid user/password'
assert.deepEqual(
  iterator.throw(mockError).value, 
  put({ type: LOGIN_ERROR, error: mockError })
)

Note we're mocking the api call result by simply injecting the mocked data into the next method of the iterator. Mocking data is way simpler than mocking functions.

The second thing to notice is the call to yield take(ACTION). Thunks are called by the action creator on each new action (e.g. LOGIN_REQUEST). i.e. actions are continually pushed to thunks, and thunks have no control on when to stop handling those actions.

In redux-saga, generators pull the next action. i.e. they have control when to listen for some action, and when to not. In the above example the flow instructions are placed inside a while(true) loop, so it'll listen for each incoming action, which somewhat mimics the thunk pushing behavior.

The pull approach allows implementing complex control flows. Suppose for example we want to add the following requirements

• Handle LOGOUT user action

• upon the first successful login, the server returns a token which expires in some delay stored in a expires_in field. We'll have to refresh the authorization in the background on each expires_in milliseconds

• Take into account that when waiting for the result of api calls (either initial login or refresh) the user may logout in-between.

How would you implement that with thunks; while also providing full test coverage for the entire flow? Here is how it may look with Sagas:

function* authorize(credentials) {
  const token = yield call(api.authorize, credentials)
  yield put( login.success(token) )
  return token
}

function* authAndRefreshTokenOnExpiry(name, password) {
  let token = yield call(authorize, {name, password})
  while(true) {
    yield call(delay, token.expires_in)
    token = yield call(authorize, {token})
  }
}

function* watchAuth() {
  while(true) {
    try {
      const {name, password} = yield take(LOGIN_REQUEST)

      yield race([
        take(LOGOUT),
        call(authAndRefreshTokenOnExpiry, name, password)
      ])

      // user logged out, next while iteration will wait for the
      // next LOGIN_REQUEST action

    } catch(error) {
      yield put( login.error(error) )
    }
  }
}

In the above example, we're expressing our concurrency requirement using race. If take(LOGOUT) wins the race (i.e. user clicked on a Logout Button). The race will automatically cancel the authAndRefreshTokenOnExpiry background task. And if the authAndRefreshTokenOnExpiry was blocked in middle of a call(authorize, {token}) call it'll also be cancelled. Cancellation propagates downward automatically.

You can find a runnable demo of the above flow

For me this worked: (using Jenkins 2.150, using simple Pipeline type - not multibranch, my branch specifier: '**')

Hint: The STRINGIZE macro above is cool, but if you make a mistake and its argument isn't a macro - you had a typo in the name, or forgot to #include the header file - then the compiler will happily put the purported macro name into the string with no error.

If you intend that the argument to STRINGIZE is always a macro with a normal C value, then

#define STRINGIZE(A) ((A),STRINGIZE_NX(A))

will expand it once and check it for validity, discard that, and then expand it again into a string.

It took me a while to figure out why STRINGIZE(ENOENT) was ending up as "ENOENT" instead of "2"... I hadn't included errno.h.

Another way is to extend Double like this:

extension Double {
   var dispatchTime: dispatch_time_t {
       get {
           return dispatch_time(DISPATCH_TIME_NOW,Int64(self * Double(NSEC_PER_SEC)))
       }
   }
}

Then you can use it like this:

dispatch_after(Double(2.0).dispatchTime, dispatch_get_main_queue(), { () -> Void in
            self.dismissViewControllerAnimated(true, completion: nil)
    })

I like matt's delay function but just out of preference I'd rather limit passing closures around.

In the future, you will be able to use a --from-lock-file (or similar) flag to install only from the package-lock.json without modifying it.

This will be useful for CI, etc. environments where reproducible builds are important.

See https://github.com/npm/npm/issues/18286 for tracking of the feature.

object count =dtFoo.Compute("count(IsActive)", "IsActive='Y'");

You can also use the .to_frame() method.

If it is a Series, I assume 'Gene' is already the index, and will remain the index after converting it to a DataFrame. The name argument of .to_frame() will name the column.

x = x.to_frame('count')

If you want them both as columns, you can reset the index:

x = x.to_frame('count').reset_index()

I am writing my answer here because it may be helpful to other readers, who might have a slightly different requirement than the questioner here.

I prepare an .xlsx template; all the cells which will be populated with dates, are already formatted as date cells (using Excel).

I open the .xlsx template using Apache POI and then just write the date to the cell, and it works.

In the example below, cell A1 is already formatted from within Excel with the format [$-409]mmm yyyy, and the Java code is used only to populate the cell.

FileInputStream inputStream = new FileInputStream(new File("Path to .xlsx template"));
Workbook wb = new XSSFWorkbook(inputStream);
Date date1=new Date();
Sheet xlsMainTable = (Sheet) wb.getSheetAt(0);
Row myRow= CellUtil.getRow(0, xlsMainTable);
CellUtil.getCell(myRow, 0).setCellValue(date1);

WHen the Excel is opened, the date is formatted correctly.

Check this

UPDATE some_table SET some_field = REPLACE("Column Name/String", 'Search String', 'Replace String')

Eg with sample string:

UPDATE some_table SET some_field = REPLACE("this is test string", 'test', 'sample')

EG with Column/Field Name:

UPDATE some_table SET some_field = REPLACE(columnName, 'test', 'sample')

This is quite an old question so I've updated this answer to take the HTML 5 email type into account.

You don't actually need JavaScript for this at all with HTML 5; just use the email input type:

<input type="email" />

• If you want to make it mandatory, you can add the required parameter.

• If you want to add additional RegEx validation (limit to @foo.com email addresses for example), you can use the pattern parameter, e.g.:

  <input type="email" pattern="[email protected]" />
  

There's more information available on MozDev.

Original answer follows

First off - I'd recommend the email validator RegEx from Hexillion: http://hexillion.com/samples/

It's pretty comprehensive - :

^(?:[\w\!\#\$\%\&\'\*\+\-\/\=\?\^\`\{\|\}\~]+\.)*[\w\!\#\$\%\&\'\*\+\-\/\=\?\^\`\{\|\}\~]+@(?:(?:(?:[a-zA-Z0-9](?:[a-zA-Z0-9\-](?!\.)){0,61}[a-zA-Z0-9]?\.)+[a-zA-Z0-9](?:[a-zA-Z0-9\-](?!$)){0,61}[a-zA-Z0-9]?)|(?:\[(?:(?:[01]?\d{1,2}|2[0-4]\d|25[0-5])\.){3}(?:[01]?\d{1,2}|2[0-4]\d|25[0-5])\]))$

I think you want a function in your JavaScript like:

function validateEmail(sEmail) {
  var reEmail = /^(?:[\w\!\#\$\%\&\'\*\+\-\/\=\?\^\`\{\|\}\~]+\.)*[\w\!\#\$\%\&\'\*\+\-\/\=\?\^\`\{\|\}\~]+@(?:(?:(?:[a-zA-Z0-9](?:[a-zA-Z0-9\-](?!\.)){0,61}[a-zA-Z0-9]?\.)+[a-zA-Z0-9](?:[a-zA-Z0-9\-](?!$)){0,61}[a-zA-Z0-9]?)|(?:\[(?:(?:[01]?\d{1,2}|2[0-4]\d|25[0-5])\.){3}(?:[01]?\d{1,2}|2[0-4]\d|25[0-5])\]))$/;

  if(!sEmail.match(reEmail)) {
    alert("Invalid email address");
    return false;
  }

  return true;

}

In the HTML input you need to trigger the event with an onblur - the easy way to do this is to simply add something like:

<input type="text" name="email" onblur="validateEmail(this.value);" />

Of course that's lacking some sanity checks and won't do domain verification (that has to be done server side) - but it should give you a pretty solid JS email format verifier.

Note: I tend to use the match() string method rather than the test() RegExp method but it shouldn't make any difference.

Have you tried this in your application.properties?

spring.jackson.time-zone= # Time zone used when formatting dates. For instance `America/Los_Angeles`

Try this from your shell:

$ od -A n -t d -N 1 /dev/urandom

Here, -t d specifies that the output format should be signed decimal; -N 1 says to read one byte from /dev/urandom.

MYISAM:

1. MYISAM supports Table-level Locking
2. MyISAM designed for need of speed
3. MyISAM does not support foreign keys hence we call MySQL with MYISAM is DBMS
4. MyISAM stores its tables, data and indexes in diskspace using separate three different files. (tablename.FRM, tablename.MYD, tablename.MYI)
5. MYISAM not supports transaction. You cannot commit and rollback with MYISAM. Once you issue a command it’s done.
6. MYISAM supports fulltext search
7. You can use MyISAM, if the table is more static with lots of select and less update and delete.

INNODB:

1. InnoDB supports Row-level Locking
2. InnoDB designed for maximum performance when processing high volume of data
3. InnoDB support foreign keys hence we call MySQL with InnoDB is RDBMS
4. InnoDB stores its tables and indexes in a tablespace
5. InnoDB supports transaction. You can commit and rollback with InnoDB

This work for me

I set style's font before and make rowheader normally then i set in loop for the style with font bolded on each cell of rowhead. Et voilà first row is bolded.

HSSFWorkbook wb = new HSSFWorkbook();
HSSFSheet sheet = wb.createSheet("FirstSheet");
HSSFRow rowhead = sheet.createRow(0); 
HSSFCellStyle style = wb.createCellStyle();
HSSFFont font = wb.createFont();
font.setFontName(HSSFFont.FONT_ARIAL);
font.setFontHeightInPoints((short)10);
font.setBold(true);
style.setFont(font);
rowhead.createCell(0).setCellValue("ID");
rowhead.createCell(1).setCellValue("First");
rowhead.createCell(2).setCellValue("Second");
rowhead.createCell(3).setCellValue("Third");
for(int j = 0; j<=3; j++)
rowhead.getCell(j).setCellStyle(style);

This might help:

<input type="number" step="1" pattern="\d+" />

step is for convenience (and could be set to another integer), but pattern does some actual enforcing.

Note that since pattern matches the whole expression, it wasn't necessary to express it as ^\d+$.

Even with this outwardly tight regular expression, Chrome and Firefox's implementations, interestingly allow for e here (presumably for scientific notation) as well as - for negative numbers, and Chrome also allows for . whereas Firefox is tighter in rejecting unless the . is followed by 0's only. (Firefox marks the field as red upon the input losing focus whereas Chrome doesn't let you input disallowed values in the first place.)

Since, as observed by others, one should always validate on the server (or on the client too, if using the value locally on the client or wishing to prevent the user from a roundtrip to the server).

unsigned int
msb32(register unsigned int x)
{
        x |= (x >> 1);
        x |= (x >> 2);
        x |= (x >> 4);
        x |= (x >> 8);
        x |= (x >> 16);
        return(x & ~(x >> 1));
}

1 register, 13 instructions. Believe it or not, this is usually faster than the BSR instruction mentioned above, which operates in linear time. This is logarithmic time.

As noted below, pandas now uses SQLAlchemy to both read from (read_sql) and insert into (to_sql) a database. The following should work

import pandas as pd

Then go to permalink setting in WordPress, set the permalink to whatever you want, then save. viola everything back to normal.

This issue occurred after I updated WordPress.

In Pro Angular-6 book is detailed as below;

• valid: This property returns true if the element’s contents are valid and false otherwise.

• invalid: This property returns true if the element’s contents are invalid and false otherwise.

• pristine: This property returns true if the element’s contents have not been changed.

• dirty: This property returns true if the element’s contents have been changed.
• untouched: This property returns true if the user has not visited the element.
• touched: This property returns true if the user has visited the element.

Don't forget: to get HTTPS contents, your OPENSSL extension should be enabled in your php.ini. (how to get contents of site use HTTPS)

You can also use this free plug-and-play extension:

http://www.magentocommerce.com/magento-connect/manage-customer-account-menu.html

This extension does not touch any of the Magento core files.

With this extension you are able to:

1. Decide per menu item to show or hide it with one click in the Magento backend.
2. Rename menu items easily.

By default, MomentJS parses in local time. If only a date string (with no time) is provided, the time defaults to midnight.

In your code, you create a local date and then convert it to the UTC timezone (in fact, it makes the moment instance switch to UTC mode), so when it is formatted, it is shifted (depending on your local time) forward or backwards.

If the local timezone is UTC+N (N being a positive number), and you parse a date-only string, you will get the previous date.

Here are some examples to illustrate it (my local time offset is UTC+3 during DST):

>>> moment('07-18-2013', 'MM-DD-YYYY').utc().format("YYYY-MM-DD HH:mm")
"2013-07-17 21:00"
>>> moment('07-18-2013 12:00', 'MM-DD-YYYY HH:mm').utc().format("YYYY-MM-DD HH:mm")
"2013-07-18 09:00"
>>> Date()
"Thu Jul 25 2013 14:28:45 GMT+0300 (Jerusalem Daylight Time)"

If you want the date-time string interpreted as UTC, you should be explicit about it:

>>> moment(new Date('07-18-2013 UTC')).utc().format("YYYY-MM-DD HH:mm")
"2013-07-18 00:00"

or, as Matt Johnson mentions in his answer, you can (and probably should) parse it as a UTC date in the first place using moment.utc() and include the format string as a second argument to prevent ambiguity.

>>> moment.utc('07-18-2013', 'MM-DD-YYYY').format("YYYY-MM-DD HH:mm")
"2013-07-18 00:00"

To go the other way around and convert a UTC date to a local date, you can use the local() method, as follows:

>>> moment.utc('07-18-2013', 'MM-DD-YYYY').local().format("YYYY-MM-DD HH:mm")
"2013-07-18 03:00"

check this quick reminder of file path

Here is all you need to know about relative file paths:

• Starting with "/" returns to the root directory and starts there
• Starting with "../" moves one directory backwards and starts there
• Starting with "../../" moves two directories backwards and starts there (and so on...)
• To move forward, just start with the first subdirectory and keep moving forward

Deleting the .vs folder in the solution solved my issue. You have to exit from Visual Studio and then delete the .vs folder and start Visual Studio again.

Note: SYSDATE - returns only date, i.e., "yyyy-mm-dd" is not correct. SYSDATE returns the system date of the database server including hours, minutes, and seconds. For example:

SELECT SYSDATE FROM DUAL; will return output similar to the following: 12/15/2017 12:42:39 PM

you can also use just like this in newer version of sql,

select year('2001-02-16 20:38:40') as year,
month('2001-02-16 20:38:40') as month,
day('2001-02-16 20:38:40') as day,
hour('2001-02-16 20:38:40') as hour,
minute('2001-02-16 20:38:40') as minute

package main

import (
    "fmt"
    "sort"
)

func main() {
    mapEg := map[string]string{"c":"a","a":"c","b":"b"}
    keys := make([]string, 0, len(mapEg))
    for k := range mapEg {
        keys = append(keys, k)
    }
    sort.Strings(keys)
    fmt.Println(keys)
}

As seen in this Angular example, there is a way to disable a button until the whole form is valid:

<button type="submit" [disabled]="!ngForm.valid">Submit</button>

Explicit access to module level variables by accessing them explicity on the module

In short: The technique described here is the same as in steveha's answer, except, that no artificial helper object is created to explicitly scope variables. Instead the module object itself is given a variable pointer, and therefore provides explicit scoping upon access from everywhere. (like assignments in local function scope).

Think of it like self for the current module instead of the current instance !

# db.py
import sys

# this is a pointer to the module object instance itself.
this = sys.modules[__name__]

# we can explicitly make assignments on it 
this.db_name = None

def initialize_db(name):
    if (this.db_name is None):
        # also in local function scope. no scope specifier like global is needed
        this.db_name = name
        # also the name remains free for local use
        db_name = "Locally scoped db_name variable. Doesn't do anything here."
    else:
        msg = "Database is already initialized to {0}."
        raise RuntimeError(msg.format(this.db_name))

As modules are cached and therefore import only once, you can import db.py as often on as many clients as you want, manipulating the same, universal state:

# client_a.py
import db

db.initialize_db('mongo')

# client_b.py
import db

if (db.db_name == 'mongo'):
    db.db_name = None  # this is the preferred way of usage, as it updates the value for all clients, because they access the same reference from the same module object

# client_c.py
from db import db_name
# be careful when importing like this, as a new reference "db_name" will
# be created in the module namespace of client_c, which points to the value 
# that "db.db_name" has at import time of "client_c".

if (db_name == 'mongo'):  # checking is fine if "db.db_name" doesn't change
    db_name = None  # be careful, because this only assigns the reference client_c.db_name to a new value, but leaves db.db_name pointing to its current value.

As an additional bonus I find it quite pythonic overall as it nicely fits Pythons policy of Explicit is better than implicit.

Try this code:

var myXmlDocument = new XmlDocument();
myXmlDocument.LoadXml(theString);

If you look up the help page, one of the arguments to lapply is the mysterious .... When we look at the Arguments section of the help page, we find the following line:

...: optional arguments to ‘FUN’.

So all you have to do is include your other argument in the lapply call as an argument, like so:

lapply(input, myfun, arg1=6)

and lapply, recognizing that arg1 is not an argument it knows what to do with, will automatically pass it on to myfun. All the other apply functions can do the same thing.

An addendum: You can use ... when you're writing your own functions, too. For example, say you write a function that calls plot at some point, and you want to be able to change the plot parameters from your function call. You could include each parameter as an argument in your function, but that's annoying. Instead you can use ... (as an argument to both your function and the call to plot within it), and have any argument that your function doesn't recognize be automatically passed on to plot.

You can use .is(':visible')

Selects all elements that are visible.

For example:

if($('#selectDiv').is(':visible')){

Also, you can get the div which is visible by:

$('div:visible').callYourFunction();

Live example:

console.log($('#selectDiv').is(':visible'));_x000D_
console.log($('#visibleDiv').is(':visible'));

#selectDiv {_x000D_
  display: none;  _x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<div id="selectDiv"></div>_x000D_
<div id="visibleDiv"></div>

One should preserve the previously associated onerror callback as well

<script type="text/javascript">

(function() {
    var errorCallback = window.onerror;
    window.onerror = function () {
        // handle error condition
        errorCallback && errorCallback.apply(this, arguments);
    };
})();

</script>

PyCharm 4.5.4

Create a file .pycharmrc in your home folder with the following contents

source ~/.bashrc
source ~/pycharmvenv/bin/activate

Using your virtualenv path as the last parameter.

Then set the shell Preferences->Project Settings->Shell path to

/bin/bash --rcfile ~/.pycharmrc

I don't why, but it doesn't work for me. PyCharm prints an error.

cmd.exe /K "<path-to-your-activate.bat>" It works, but it creates the same virtualenv for each project, and even if this is not necessary.

This receipt is working! But the string /env_yourenvlocate/scripts/activate.bat must contain quotes, like this "Full_path_to_your_env_locate\scripts\activate.bat"!

Deactivate the virtualenv is very easy - type in the terminal 'deactivate'

(virt_env) D:\Projects\src>deactivate
D:\Projects\src>

You can always, reshape like:

temp = [1,2,3,4,5,5,6,7]

temp = temp.reshape(len(temp), 1)

Because, the major issue is when your, temp.shape is: (8,)

and you need (8,1)

There's an important thing that people always seem to overlook:

You can pass a plain array to something which accepts an IList<T> parameter, and then you can call IList.Add() and will receive a runtime exception:

Unhandled Exception: System.NotSupportedException: Collection was of a fixed size.

For example, consider the following code:

private void test(IList<int> list)
{
    list.Add(1);
}

If you call that as follows, you will get a runtime exception:

int[] array = new int[0];
test(array);

This happens because using plain arrays with IList<T> violates the Liskov substitution principle.

For this reason, if you are calling IList<T>.Add() you may want to consider requiring a List<T> instead of an IList<T>.

The docs for Google Test 1.7 suggest:

"If you have a broken test that you cannot fix right away, you can add the DISABLED_ prefix to its name. This will exclude it from execution."

Examples:

// Tests that Foo does Abc.
TEST(FooTest, DISABLED_DoesAbc) { ... }

class DISABLED_BarTest : public ::testing::Test { ... };

// Tests that Bar does Xyz.
TEST_F(DISABLED_BarTest, DoesXyz) { ... }

The Go trough this link state that the first argument of Output() is the file path, second is the saving mode - you need to set it to 'F'.

 $upload_dir = public_path(); 
             $filename = $upload_dir.'/testing7.pdf'; 
              $mpdf = new \Mpdf\Mpdf();
              //$test = $mpdf->Image($pro_image, 0, 0, 50, 50);

              $html ='<h1> Project Heading </h1>';
              $mail = ' <p> Project Heading </p> ';
              
              $mpdf->autoScriptToLang = true;
              $mpdf->autoLangToFont = true;
              $mpdf->WriteHTML($mail);

              $mpdf->Output($filename,'F'); 
              $mpdf->debug = true;

Example :

 $mpdf->Output($filename,'F');

Example #2

$mpdf = new \Mpdf\Mpdf();
$mpdf->WriteHTML('Hello World');

// Saves file on the server as 'filename.pdf'
$mpdf->Output('filename.pdf', \Mpdf\Output\Destination::FILE);

If your using Office 2016 or later, or Office 365, there is a new function that acts similarly to a CASE function called IFS. Here's the description of the function from Microsoft's documentation:

The IFS function checks whether one or more conditions are met, and returns a value that corresponds to the first TRUE condition. IFS can take the place of multiple nested IF statements, and is much easier to read with multiple conditions.

An example of usage follows:

=IFS(A2>89,"A",A2>79,"B",A2>69,"C",A2>59,"D",TRUE,"F")

You can even specify a default result:

To specify a default result, enter TRUE for your final logical_test argument. If none of the other conditions are met, the corresponding value will be returned.

The default result feature is included in the example shown above.

You can read more about it on Microsoft's Support Documentation

Step 1:

select object_name, s.sid, s.serial#, p.spid 
from v$locked_object l, dba_objects o, v$session s, v$process p
where l.object_id = o.object_id and l.session_id = s.sid and s.paddr = p.addr;

Step 2:

alter system kill session 'sid,serial#'; --`sid` and `serial#` get from step 1

Found an alternative at Child elements with margins within DIVs You can also add:

.parent { overflow: auto; }

or:

.parent { overflow: hidden; }

This prevents the margins to collapse. Border and padding do the same. Hence, you can also use the following to prevent a top-margin collapse:

.parent {
    padding-top: 1px;
    margin-top: -1px;
}

Update by popular request: The whole point of collapsing margins is handling textual content. For example:

h1, h2, p, ul {_x000D_
  margin-top: 1em;_x000D_
  margin-bottom: 1em;_x000D_
}

<h1>Title!</h1>_x000D_
<div class="text">_x000D_
  <h2>Title!</h2>_x000D_
  <p>Paragraph</p>_x000D_
</div>_x000D_
<div class="text">_x000D_
  <h2>Title!</h2>_x000D_
  <p>Paragraph</p>_x000D_
  <ul>_x000D_
    <li>list item</li>_x000D_
  </ul>_x000D_
</div>

Because the browser collapses margins, the text would appear as you'd expect, and the <div> wrapper tags don't influence the margins. Each element ensures it has spacing around it, but spacing won't be doubled. The margins of the <h2> and <p> won't add up, but slide into each other (they collapse). The same happens for the <p> and <ul> element.

Sadly, with modern designs this idea can bite you when you explicitly want a container. This is called a new block formatting context in CSS speak. The overflow or margin trick will give you that.

You have to validate the connection.

If you use Oracle it is likely that you use Oracle´s Universal Connection Pool. The following assumes that you do so.

The easiest way to validate the connection is to tell Oracle that the connection must be validated while borrowing it. This can be done with

pool.setValidateConnectionOnBorrow(true);

But it works only if you hold the connection for a short period. If you borrow the connection for a longer time, it is likely that the connection gets broken while you hold it. In that case you have to validate the connection explicitly with

if (connection == null || !((ValidConnection) connection).isValid())

See the Oracle documentation for further details.

This can be done by two ways according to your Android OS.

1. You can use android:largeHeap="true" in application tag of Android manifest to request a larger heap size, but this will not work on any pre Honeycomb devices.
2. On pre 2.3 devices, you can use the VMRuntime class, but this will not work on Gingerbread and above See below how to do it.

VMRuntime.getRuntime().setMinimumHeapSize(BIGGER_SIZE);

Before Setting HeapSize make sure that you have entered the appropriate size which will not affect other application or OS functionality. Before settings just check how much size your app takes & then set the size just to fulfill your job. Dont use so much of memory otherwise other apps might affect.

If you want to use the new android.support.v7.app.AlertDialog and have different colors for the buttons and also have a custom layout then have a look at my https://gist.github.com/JoachimR/6bfbc175d5c8116d411e

@NonNull
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {

    View v = inflater.inflate(R.layout.custom_layout, null);

    initDialogUi(v);

    final AlertDialog d = new AlertDialog.Builder(activity, R.style.AppCompatAlertDialogStyle)
            .setTitle(getString(R.string.some_dialog_title))
            .setCancelable(true)
            .setPositiveButton(activity.getString(R.string.some_dialog_title_btn_positive),
                    new DialogInterface.OnClickListener() {
                        @Override
                        public void onClick(DialogInterface dialog, int which) {
                            doSomething();
                            dismiss();
                        }
                    })
            .setNegativeButton(activity.getString(R.string.some_dialog_title_btn_negative),
                    new DialogInterface.OnClickListener() {
                        @Override
                        public void onClick(DialogInterface dialog, int which) {
                            dismiss();
                        }
                    })
            .setView(v)
            .create();

    // change color of positive button         
    d.setOnShowListener(new DialogInterface.OnShowListener() {
        @Override
        public void onShow(DialogInterface dialog) {
            Button b = d.getButton(DialogInterface.BUTTON_POSITIVE);
            b.setTextColor(getResources().getColor(R.color.colorPrimary));
        }
    });

    return d;
}

Here's an answer that actually gives the solution the OP asked for:

>>> d = {320:1, 321:0, 322:3}
>>> d.items()
[(320, 1), (321, 0), (322, 3)]
>>> # find the minimum by comparing the second element of each tuple
>>> min(d.items(), key=lambda x: x[1]) 
(321, 0)

Using d.iteritems() will be more efficient for larger dictionaries, however.

@Adam Augusta is right, One more thing

Apache-HTTP client jars also comes in same category as some google-apis.

org.apache.httpcomponents.httpclient_4.2.jar and commons-codec-1.4.jar both on classpath, This is very possible that you will get this problem.

This prove to all jars which are using early version of common-codec internally and at the same time someone using common-codec explicitly on classpath too.
