Programs & Examples On #Topdown

I think you could experiment with different activity flags, as it sounds like multiple instances.

"singleTop" "singleTask" "singleInstance"

Are the ones I would try, they can be defined inside the manifest.

http://developer.android.com/guide/topics/manifest/activity-element.html

This can replace the MaxLength and the MinLength

[StringLength(40, MinimumLength = 10 , ErrorMessage = "Password cannot be longer than 40 characters and less than 10 characters")]

If you are not using SSMS then here is the syntax:

ALTER TABLE <table_name>
ADD <constraint_name> FOREIGN KEY 
(<column_name1> ,
<column_name2> )
REFERENCES <table_name>
(<column_name1> ,
<column_name2>)

http://infogoal.com/sql/sql-add-foreignkey.htm

<div style="specify your dimension:overflow:hidden">
    <div style="margin-top:-50px">
       <img ...  />
    </div>
</div>

The above will crop 50px from the top of the image. You may want to compute to come up wit a top margin that will fit your requirements based on the dimension of the image.

To crop from the bottom simply specify the height of the outer div and remove the inner div. Apply the same principle to crop from the sides.

Yet another AWK solution

Run

awk '{printf "%s", $c; while(getline){printf "%s%s", sep, $c}}' c=2 sep=','

to use the 2nd column to form the list separated by commas. Give the input as usual in standard input or as a file name argument.

You can use either:

ActiveCell.Interior.ColorIndex = 28

or

ActiveCell.Interior.Color = RGB(255,0,0)

display: block;
text-align: center;

If you are using 1.0, try making a custom templatetag that looks like this:

def adminpageurl(object, link=None):
    if link is None:
        link = object
    return "<a href=\"/admin/%s/%s/%d\">%s</a>" % (
        instance._meta.app_label,
        instance._meta.module_name,
        instance.id,
        link,
    )

then just use {% adminpageurl my_object %} in your template (don't forget to load the templatetag first)

I newer version of xampp you may use another method first open your httpd-xampp.conf file and find the string "phpmyadmin" using ctrl+F command (Windows). and then replace this code

Alias /phpmyadmin "D:/server/phpMyAdmin/"
<Directory "D:/server/phpMyAdmin">
    AllowOverride AuthConfig
    Require local
    ErrorDocument 403 /error/XAMPP_FORBIDDEN.html.var
</Directory>

with this

Alias /phpmyadmin "D:/server/phpMyAdmin/"
<Directory "D:/server/phpMyAdmin">
    AllowOverride AuthConfig
    Require all granted
    ErrorDocument 403 /error/XAMPP_FORBIDDEN.html.var
</Directory>

Don't Forget to Restart your Xampp.

The following works for me:

class Fruits: pass

banana = Fruits()

banana.color = 'yellow'
banana.value = 30

import pickle

filehandler = open("Fruits.obj","wb")
pickle.dump(banana,filehandler)
filehandler.close()

file = open("Fruits.obj",'rb')
object_file = pickle.load(file)
file.close()

print(object_file.color, object_file.value, sep=', ')
# yellow, 30

Try:

<c:if test = "${ansokanInfo.PSystem == 'NAT'}">

JSP/Servlet 2.4 (I think that's the version number) doesn't support method calls in EL and only support properties. The latest servlet containers do support method calls (ie Tomcat 7).

You should use "Microsoft OLE DB Provider for ODBC Drivers" to get to access to Microsoft Access. Here is the sample tutorial on using it

http://msdn.microsoft.com/en-us/library/aa288452(v=vs.71).aspx

This work for me

Demo: jsfiddle

$(function() 
{
    Fixed_Header();
});

function Fixed_Header()
{
    $('.User_Table thead').css({'position': 'absolute'});
    $('.User_Table tbody tr:eq("2") td').each(function(index,e){
        $('.User_Table thead tr th:eq("'+index+'")').css({'width' : $(this).outerWidth() +"px" });
    });
    var Header_Height = $('.User_Table thead').outerHeight();
    $('.User_Table thead').css({'margin-top' : "-"+Header_Height+"px"});
    $('.User_Table').css({'margin-top' : Header_Height+"px"});
}

Since you are the only user:

git reset --hard HEAD@{1}
git push -f
git reset --hard HEAD@{1}

( basically, go back one commit, force push to the repo, then go back again - remove the last step if you don't care about the commit )

Without doing any changes to your local repo, you can also do something like:

git push -f origin <sha_of_previous_commit>:master

Generally, in published repos, it is safer to do git revert and then git push

Here is a cool way of ensuring zoom in and zoom out with mouse scroll-wheel in the Eclipse Editor. This one takes inspiration from the solution above from naveed ahmad which was not working for me.

1) First download Autohotkey from http://www.autohotkey.com/ and install it, then run it.

2) Then download tarlog-plugins from https://code.google.com/p/tarlog-plugins/downloads/list

3) Put the downloaded .jar file in the eclipse/plugins folder.

4) Restart Eclipse.

5) Add the following Autohotkey script, save it then reload it (right click on Autohotkey icon in taskbar and click "Reload this script")

; Ctrl + MouseWheel zooming in Eclipse Editor.
; Requires Tarlog plugins (https://code.google.com/p/tarlog-plugins/).
#IfWinActive ahk_class SWT_Window0
^WheelUp:: Send ^{NumpadAdd}
^WheelDown:: Send ^{NumpadSub}
#IfWinActive

And you should be done. You can now zoom in or zoom out with ctrl+mousewheel up and ctrl+mousewheel down. The only caveat is that Autohotkey must be running for this solution to work so ensure that it starts with Windows or run it just before firing Eclipse up. Works fine in Eclipse Kepler and Luna.

Convert RGB to Hex

I am using Jasmine protractor and I was getting errors like - Expected [ 'rgba(255, 255, 255, 1)' ] to contain '#fff'. Below function worked fine for me.

function RGBAToHexA(test:string) {
let sep = test.toString().indexOf(",") > -1 ? "," : " ";
const rgba = test.toString().substring(5).split(")")[0].split(sep);
console.log(rgba)
let r = (+rgba[0]).toString(16),
  g = (+rgba[1]).toString(16),
  b = (+rgba[2]).toString(16),
  a = Math.round(+rgba[3] * 255).toString(16);

    if (r.length == 1)
        r = "0" + r;
    if (g.length == 1)
        g = "0" + g;
    if (b.length == 1)
        b = "0" + b;
    if (a.length == 1)
        a = "0" + a;

return "#" + r + g + b + a;

}

describe('Check CSS', function() {
 
it('should check css of login page', async function(){
        browser.waitForAngularEnabled(true);
        browser.actions().mouseMove(element(by.css('.btn-auth, .btn-auth:hover'))).perform(); // mouse hover on button
        csspage.Loc_auth_btn.getCssValue('color').then(function(color){
            console.log(RGBAToHexA(color))
            expect( RGBAToHexA(color)).toContain(cssData.hoverauth.color);

        })

       

Mapping the WebDAV folder is my preferred method of creating an easily accessible, long-term connection to SharePoint. However, you'll find—even when properly mapped—that a file will return a URL when selected (especially via Application.FileDialog) due to changes in Windows 10 1803.

To circumvent this, you can map the drive using DriveMapper (or an equivalent) and then combine the resulting Application.FileDialog.SelectedItems with a URL to UNC converter function:

Public Function SharePointURLtoUNC( _
  sURL As String) _
As String
  Dim bIsSSL As Boolean

  bIsSSL = InStr(1, sURL, "https:") > 0
  sURL = Replace(Replace(sURL, "/", "\"), "%20", " ")
  sURL = Replace(Replace(sURL, "https:", vbNullString), "http:", vbNullString)
  
  sURL= Replace(sURL, Split(sURL, "\")(2), Split(sURL, "\")(2) & "@SSL\DavWWWRoot")
  If Not bIsSSL Then sURL = Replace(sURL, "@SSL\", vbNullString) 
  SharePointURLtoUNC = sURL
End Function

I change all code to lower case for mono android

Yes.

Constructors are nothing more than special methods, and can throw exceptions like any other method.

A Context represents your environment. It represents the state surrounding where you are in your system.

For example, in web programming in Java, you have a Request, and a Response. These are passed to the service method of a Servlet.

A property of the Servlet is the ServletConfig, and within that is a ServletContext.

The ServletContext is used to tell the servlet about the Container that the Servlet is within.

So, the ServletContext represents the servlets environment within its container.

Similarly, in Java EE, you have EBJContexts that elements (like session beans) can access to work with their containers.

Those are two examples of contexts used in Java today.

Edit --

You mention Android.

Look here: http://developer.android.com/reference/android/content/Context.html

You can see how this Context gives you all sorts of information about where the Android app is deployed and what's available to it.

You need to have the System.Linq namespace included in your view since Select is an extension method. You have a couple of options on how to do this:

Add @using System.Linq to the top of your cshtml file.

If you find that you will be using this namespace often in many of your views, you can do this for all views by modifying the web.config inside of your Views folder (not the one at the root). You should see a pages/namespace XML element, create a new add child that adds System.Linq. Here is an example:

<configuration>
    <system.web.webPages.razor>
        <pages>
            <namespaces>
                <add namespace="System.Linq" />
            </namespaces>
        </pages>
    </system.web.webPages.razor>
</configuration>

The code that you looked at is not ideal. You should either:

1. Catch the exception and handle it; in which case the throws is unnecesary.

2. Remove the try/catch; in which case the Exception will be handled by a calling method.

3. Catch the exception, possibly perform some action and then rethrow the exception (not just the message)

Basic syntax is: $(selector).action()

A dollar sign to define jQuery A (selector) to "query (or find)" HTML elements A jQuery action() to be performed on the element(s)

Definitely regex:

string CleanPhone(string phone)
{
    Regex digitsOnly = new Regex(@"[^\d]");   
    return digitsOnly.Replace(phone, "");
}

or within a class to avoid re-creating the regex all the time:

private static Regex digitsOnly = new Regex(@"[^\d]");   

public static string CleanPhone(string phone)
{
    return digitsOnly.Replace(phone, "");
}

Depending on your real-world inputs, you may want some additional logic there to do things like strip out leading 1's (for long distance) or anything trailing an x or X (for extensions).

Pocoo's click is more intuitive, requires less boilerplate, and is at least as powerful as argparse.

The only weakness I've encountered so far is that you can't do much customization to help pages, but that usually isn't a requirement and docopt seems like the clear choice when it is.

Ensures that the object is displayed (or should be) only to readers and similar devices. It give more sense in context with other element with attribute aria-hidden="true".

<div class="alert alert-danger" role="alert">
  <span class="glyphicon glyphicon-exclamation-sign" aria-hidden="true"></span>
  <span class="sr-only">Error:</span>
  Enter a valid email address
</div>

Glyphicon will be displayed on all other devices, word Error: on text readers.

Roughly the same kinds of things you've done in C#. Calling getch() is probably the simplest.

newer .net versions allow you to use $ in front of the literal which allows you to use variables inside like follows:

var x = $"Line 1{Environment.NewLine}Line 2{Environment.NewLine}Line 3";

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

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

Generally .equals is used for Object comparison, where you want to verify if two Objects have an identical value.

== for reference comparison (are the two Objects the same Object on the heap) & to check if the Object is null. It is also used to compare the values of primitive types.

I use PowerShell to re-launch the script elevated if it's not. Put these lines at the very top of your script.

net file 1>nul 2>nul && goto :run || powershell -ex unrestricted -Command "Start-Process -Verb RunAs -FilePath '%comspec%' -ArgumentList '/c %~fnx0 %*'"
goto :eof
:run
:: TODO: Put code here that needs elevation

I copied the 'net name' method from @Matt's answer. His answer is much better documented and has error messages and the like. This one has the advantage that PowerShell is already installed and available on Windows 7 and up. No temporary VBScript (*.vbs) files, and you don't have to download tools.

This method should work without any configuration or setup, as long as your PowerShell execution permissions aren't locked down.

Jupytext allows for such a conversion on the command line, and importantly you can go back again from the script to a notebook (even an executed notebook). See here.

Can also use:

find . -mindepth 1 -mtime +3 -delete

To not delete target directory

var text = "\"http://example.com\""; 

Whatever your text, to wrap it with ", you need to put them and escape inner ones with \. Above will result in:

"http://example.com"

So I wrote a function that would get the POST data from the php://input stream.

So the challenge here was switching to PUT, DELETE OR PATCH request method, and still obtain the post data that was sent with that request.

I'm sharing this maybe for someone with a similar challenge. The function below is what I came up with and it works. I hope it helps!

    /**
     * @method Post getPostData
     * @return array
     * 
     * Convert Content-Disposition to a post data
     */
    function getPostData() : array
    {
        // @var string $input
        $input = file_get_contents('php://input');

        // continue if $_POST is empty
        if (strlen($input) > 0 && count($_POST) == 0 || count($_POST) > 0) :

            $postsize = "---".sha1(strlen($input))."---";

            preg_match_all('/([-]{2,})([^\s]+)[\n|\s]{0,}/', $input, $match);

            // update input
            if (count($match) > 0) $input = preg_replace('/([-]{2,})([^\s]+)[\n|\s]{0,}/', '', $input);

            // extract the content-disposition
            preg_match_all("/(Content-Disposition: form-data; name=)+(.*)/m", $input, $matches);

            // let's get the keys
            if (count($matches) > 0 && count($matches[0]) > 0)
            {
                $keys = $matches[2];

                foreach ($keys as $index => $key) :
                    $key = trim($key);
                    $key = preg_replace('/^["]/','',$key);
                    $key = preg_replace('/["]$/','',$key);
                    $key = preg_replace('/[\s]/','',$key);
                    $keys[$index] = $key;
                endforeach;

                $input = preg_replace("/(Content-Disposition: form-data; name=)+(.*)/m", $postsize, $input);

                $input = preg_replace("/(Content-Length: )+([^\n]+)/im", '', $input);

                // now let's get key value
                $inputArr = explode($postsize, $input);

                // @var array $values
                $values = [];

                foreach ($inputArr as $index => $val) :
                    $val = preg_replace('/[\n]/','',$val);

                    if (preg_match('/[\S]/', $val)) $values[$index] = trim($val);

                endforeach;

                // now combine the key to the values
                $post = [];

                foreach ($keys as $x => $key) $post[$key] = isset($value[$x]) ? $value[$x] : '';

Have you tried transpose yet? Like (from the other answer)

 ffmpeg -i input -vf transpose=2 output

If you are using an old version, you have to update ffmpeg if you want to use the transpose feature, as it was added in October 2011.

The FFmpeg download page offers static builds that you can directly execute without having to compile them.

You can include it in the same where statement with the && operator...

x=> x.Lists.Include(l => l.Title).Where(l=>l.Title != String.Empty 
    && l.InternalName != String.Empty)

You can use any of the comparison operators (think of it like doing an if statement) such as...

List<Int32> nums = new List<int>();

nums.Add(3);
nums.Add(10);
nums.Add(5);

var results = nums.Where(x => x == 3 || x == 10);

...would bring back 3 and 10.

This should do it for you:

new_list = list(set(old_list))

set will automatically remove duplicates. list will cast it back to a list.

On modern Windows this driver isn't available by default anymore, but you can download as Microsoft Access Database Engine 2010 Redistributable on the MS site. If your app is 32 bits be sure to download and install the 32 bits variant because to my knowledge the 32 and 64 bit variant cannot coexist.

Depending on how your app locates its db driver, that might be all that's needed. However, if you use an UDL file there's one extra step - you need to edit that file. Unfortunately, on a 64bits machine the wizard used to edit UDL files is 64 bits by default, it won't see the JET driver and just slap whatever driver it finds first in the UDL file. There are 2 ways to solve this issue:

1. start the 32 bits UDL wizard like this: C:\Windows\syswow64\rundll32.exe "C:\Program Files (x86)\Common Files\System\Ole DB\oledb32.dll",OpenDSLFile C:\path\to\your.udl. Note that I could use this technique on a Win7 64 Pro, but it didn't work on a Server 2008R2 (could be my mistake, just mentioning)
2. open the UDL file in Notepad or another text editor, it should more or less have this format:

[oledb] ; Everything after this line is an OLE DB initstring Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\Path\To\The\database.mdb;Persist Security Info=False

That should allow your app to start correctly.

if you want see select query output in pl/sql you need to use a explicit cursor. Which will hold active data set and by fetching each row at a time it will show all the record from active data set as long as it fetches record from data set by iterating in loop. This data will not be generated in tabular format this result will be in plain text format. Hope this will be helpful. For any other query you may ask....

set serveroutput on;
declare
cursor c1 is
   select foo, bar from foobar;
begin
  for i in c1 loop
    dbms_output.put_line(i.foo || ' ' || i.bar);
  end loop;
end;

If you want to convert from char to int, why not think about unicode number?

SELECT UNICODE(';') -- 59

This way you can convert any char to int without any error. Cheers.

NSUnderlineStyleAttributeName which takes an NSNumber (where 0 is no underline) can be added to an attribute dictionary. I don't know if this is any easier. But, it was easier for my purposes.

    NSDictionary *attributes; 
    attributes = @{NSFontAttributeName:font,   NSParagraphStyleAttributeName: style, NSUnderlineStyleAttributeName:[NSNumber numberWithInteger:1]};

    [text drawInRect:CGRectMake(self.contentRect.origin.x, currentY, maximumSize.width, textRect.size.height) withAttributes:attributes];

You are using the same connection for the DataReader and the ExecuteNonQuery. This is not supported, according to MSDN:

Note that while a DataReader is open, the Connection is in use exclusively by that DataReader. You cannot execute any commands for the Connection, including creating another DataReader, until the original DataReader is closed.

Updated 2018: link to MSDN

That pattern will create a new execution context (EC) in which any local variable objects (VO's) will live, and will likewise die when the EC exits. The only exception to this lifetime is for VO's which become part of a closure.

Please note that JavaScript has no magic "init" function. You might associate this pattern with such since most any self-respecting JS library (jQuery, YUI, etc.) will do this so that they don't pollute the global NS more than they need to.

A demonstration:

var x = 1; // global VO
(function(){        
    var x = 2; // local VO
})();
x == 1; // global VO, unchanged by the local VO

The 2nd set of "brackets" (those are actually called parens, or a set of parentheses), are simply to invoke the function expression directly preceding it (as defined by the prior set of parenthesis).

There's a polyfill for Encoding over on Github: text-encoding. It's easy for Node or the browser, and the Readme advises the following:

var uint8array = TextEncoder(encoding).encode(string);
var string = TextDecoder(encoding).decode(uint8array);

If I recall, 'utf-8' is the encoding you need, and of course you'll need to wrap your buffer:

var uint8array = new Uint8Array(utf8buffer);

Hope it works as well for you as it has for me.

Here is a simple trick to remember the difference between slice vs splice

var a=['j','u','r','g','e','n'];

// array.slice(startIndex, endIndex)
a.slice(2,3);
// => ["r"]

//array.splice(startIndex, deleteCount)
a.splice(2,3);
// => ["r","g","e"]

Trick to remember:

Think of "spl" (first 3 letters of splice) as short for "specifiy length", that the second argument should be a length not an index

In my case, my script has parameters, so I set:

Arguments: -Command "& C:\scripts\myscript.ps1 myParam1 myParam2"

This is likely due to your app exceeding the 65k method count, thus causing a dex error. There is no solution, other than enabling multidexing in your app.

I tried in online compiler https://www.onlinegdb.com/online_c++_compiler

int main()
{
    cout<<"Hello World";
    int x = 10;
    int *p = &x;
    printf("\nAddress of x is %p\n", &x); // 0x7ffc7df0ea54
    printf("Address of p is %p\n", p);    // 0x7ffc7df0ea54

    return 0;
}

Adding the GridView1.DataBind() to the button click event did not work for me. However, adding it to the SqlDataSource1_Updated event did though.

Protected Sub SqlDataSource1_Updated(sender As Object, e As SqlDataSourceStatusEventArgs) Handles SqlDataSource1.Updated
    GridView1.DataBind()
End Sub

I think the best way, is to use a Propper Form and to use jQuery.serializeArray.

<!-- a form with any type of input -->
<form class="a-form">
    <select name="field[something]">...</select>
    <input type="checkbox" name="field[somethingelse]" ... />
    <input type="radio" name="field[somethingelse2]" ... />
    <input type="text" name="field[somethingelse3]" ... />
</form>

<!-- sample ajax call -->
<script>
$(document).ready(function(){
    $.ajax({
        url: 'submit.php',
        type: 'post',
        data: $('form.a-form').serializeArray(),
        success: function(response){
            ...
        }
    });
});
</script>

The Values will be available in PHP as $_POST['field'][INDEX].

I encountered this issue when trying to invoke the update method with a parameter of a wrong type. The expected dict was:

{'foo': True}

The one that was passed was:

{'foo': "True"}

make sure you check all the parameters you pass are of the expected type.

Disallow Nulls on the column and set a default on the column of getdate()

/*Deal with any existing NULLs*/
UPDATE YourTable SET created_date=GETDATE() /*Or some sentinel value 
                                                '19000101' maybe?*/
WHERE created_date IS NULL


/*Disallow NULLs*/
ALTER TABLE YourTable ALTER COLUMN created_date DATE NOT NULL

/*Add default constraint*/
ALTER TABLE YourTable ADD CONSTRAINT
    DF_YourTable_created_date DEFAULT GETDATE() FOR created_date

Yes, %d means decimal, but it means decimal number system, not decimal point.

Further, as a complement to the former post, you can also control the number of decimal points to show. Try this,

System.out.printf("%.2f %.1f",d,f); // prints 1.20 1.2

For more please refer to the API docs.

I found the answer to this question here..... The problem was hosting server... I thank all who tried .... Hope this will help others

Godaddy Installation Tips

Update: as of Python 3.7, insertion order is maintained, so you don't need an OrderedDict here. You can use the below approaches with a normal dict

Changed in version 3.7: Dictionary order is guaranteed to be insertion order. This behavior was an implementation detail of CPython from 3.6.

source

Python 3.6 and earlier*

If you are talking about a regular dict, then the "first key" doesn't mean anything. The keys are not ordered in any way you can depend on. If you iterate over your dict you will likely not get "banana" as the first thing you see.

If you need to keep things in order, then you have to use an OrderedDict and not just a plain dictionary.

import collections
prices  = collections.OrderedDict([
        ("banana", 4),
        ("apple", 2),
        ("orange", 1.5),
        ("pear", 3),
])

If you then wanted to see all the keys in order you could do so by iterating through it

for k in prices:
    print(k)

You could, alternatively put all of the keys into a list and then work with that

ks = list(prices)
print(ks[0]) # will print "banana"

A faster way to get the first element without creating a list would be to call next on the iterator. This doesn't generalize nicely when trying to get the nth element though

>>> next(iter(prices))
'banana'

_{* CPython had guaranteed insertion order as an implementation detail in 3.6.}

you can try this solution, is the best... url(github)

// Transparent Background

    }
  }
}

// Generate semi-transparent backgrounds for the colors we want
@include transparent-shades('dark', #000000);
@include transparent-shades('light', #ffffff);

Native way to get the mimetype:

For PHP < 5.3 use mime_content_type()
For PHP >= 5.3 use finfo_open() or mime_content_type()

Alternatives to get the MimeType are exif_imagetype and getimagesize, but these rely on having the appropriate libs installed. In addition, they will likely just return image mimetypes, instead of the whole list given in magic.mime.

While mime_content_type is available from PHP 4.3 and is part of the FileInfo extension (which is enabled by default since PHP 5.3, except for Windows platforms, where it must be enabled manually, for details see here).

If you don't want to bother about what is available on your system, just wrap all four functions into a proxy method that delegates the function call to whatever is available, e.g.

function getMimeType($filename)
{
    $mimetype = false;
    if(function_exists('finfo_open')) {
        // open with FileInfo
    } elseif(function_exists('getimagesize')) {
        // open with GD
    } elseif(function_exists('exif_imagetype')) {
       // open with EXIF
    } elseif(function_exists('mime_content_type')) {
       $mimetype = mime_content_type($filename);
    }
    return $mimetype;
}

I have read that any variable declared outside a function is a global variable. I have done so, but in another *.cpp File that variable could not be found. So it was not realy global.

According to the concept of scope, your variable is global. However, what you've read/understood is overly-simplified.

Possibility 1

Perhaps you forgot to declare the variable in the other translation unit (TU). Here's an example:

a.cpp

int x = 5; // declaration and definition of my global variable

b.cpp

// I want to use `x` here, too.
// But I need b.cpp to know that it exists, first:
extern int x; // declaration (not definition)

void foo() {
   cout << x;  // OK
}

Typically you'd place extern int x; in a header file that gets included into b.cpp, and also into any other TU that ends up needing to use x.

Possibility 2

Additionally, it's possible that the variable has internal linkage, meaning that it's not exposed across translation units. This will be the case by default if the variable is marked const ([C++11: 3.5/3]):

a.cpp

const int x = 5; // file-`static` by default, because `const`

b.cpp

extern const int x;    // says there's a `x` that we can use somewhere...

void foo() {
   cout << x;    // ... but actually there isn't. So, linker error.
}

You could fix this by applying extern to the definition, too:

a.cpp

extern const int x = 5;

This whole malarky is roughly equivalent to the mess you go through making functions visible/usable across TU boundaries, but with some differences in how you go about it.

Create a mutable map without initial value:

scala> var d= collection.mutable.Map[Any, Any]()
d: scala.collection.mutable.Map[Any,Any] = Map()

Create a mutable map with initial values:

scala> var d= collection.mutable.Map[Any, Any]("a"->3,1->234,2->"test")
d: scala.collection.mutable.Map[Any,Any] = Map(2 -> test, a -> 3, 1 -> 234)

Update existing key-value:

scala> d("a")= "ABC"

Add new key-value:

scala> d(100)= "new element"

Check the updated map:

scala> d
res123: scala.collection.mutable.Map[Any,Any] = Map(2 -> test, 100 -> new element, a -> ABC, 1 -> 234)

In my case I was using an ssh key with a password to authenticate with github. I hadn't set up pageant properly in Windows (only in cygwin). The missing steps were to point the git_ssh environment variable to plink.exe. Also, you need to get github.com into the plink known_hosts.

   plink github.com
   y
   <then ctrl-c>

Hope this helps!

I sure wish intellij would have given me a more useful error, or better yet asked me to type in the ssh key password.

There is no need to use foreign libraries.

Convert a BitmapImage to Bitmap:

private Bitmap BitmapImage2Bitmap(BitmapImage bitmapImage)
{
    // BitmapImage bitmapImage = new BitmapImage(new Uri("../Images/test.png", UriKind.Relative));

    using(MemoryStream outStream = new MemoryStream())
    {
        BitmapEncoder enc = new BmpBitmapEncoder();
        enc.Frames.Add(BitmapFrame.Create(bitmapImage));
        enc.Save(outStream);
        System.Drawing.Bitmap bitmap = new System.Drawing.Bitmap(outStream);

        return new Bitmap(bitmap);
    }
}

To convert the Bitmap back to a BitmapImage:

[System.Runtime.InteropServices.DllImport("gdi32.dll")]
public static extern bool DeleteObject(IntPtr hObject);

private BitmapImage Bitmap2BitmapImage(Bitmap bitmap)
{
    IntPtr hBitmap = bitmap.GetHbitmap();
    BitmapImage retval;

    try
    {
        retval = (BitmapImage)Imaging.CreateBitmapSourceFromHBitmap(
                     hBitmap,
                     IntPtr.Zero,
                     Int32Rect.Empty,
                     BitmapSizeOptions.FromEmptyOptions());
    }
    finally
    {
        DeleteObject(hBitmap);
    }

    return retval;
}

After reading this question, I was intrigued by the fact that some answers offered optimization by running a loop with multiples of 2*3=6.

So I create a new function with the same idea, but with multiples of 2*3*5=30.

int check235(unsigned long n)
{
    unsigned long sq, i;

    if(n<=3||n==5)
        return n>1;

    if(n%2==0 || n%3==0 || n%5==0)
        return 0;

    if(n<=30)
        return checkprime(n); /* use another simplified function */

    sq=ceil(sqrt(n));
    for(i=7; i<=sq; i+=30)
        if (n%i==0 || n%(i+4)==0 || n%(i+6)==0 || n%(i+10)==0 || n%(i+12)==0 
           || n%(i+16)==0 || n%(i+22)==0 || n%(i+24)==0)
            return 0;

        return 1;
}

By running both functions and checking times I could state that this function is really faster. Lets see 2 tests with 2 different primes:

$ time ./testprimebool.x 18446744069414584321 0
f(2,3)
Yes, its prime.    
real    0m14.090s
user    0m14.096s
sys     0m0.000s

$ time ./testprimebool.x 18446744069414584321 1
f(2,3,5)
Yes, its prime.    
real    0m9.961s
user    0m9.964s
sys     0m0.000s

$ time ./testprimebool.x 18446744065119617029 0
f(2,3)
Yes, its prime.    
real    0m13.990s
user    0m13.996s
sys     0m0.004s

$ time ./testprimebool.x 18446744065119617029 1
f(2,3,5)
Yes, its prime.    
real    0m10.077s
user    0m10.068s
sys     0m0.004s

So I thought, would someone gain too much if generalized? I came up with a function that will do a siege first to clean a given list of primordial primes, and then use this list to calculate the bigger one.

int checkn(unsigned long n, unsigned long *p, unsigned long t)
{
    unsigned long sq, i, j, qt=1, rt=0;
    unsigned long *q, *r;

    if(n<2)
        return 0;

    for(i=0; i<t; i++)
    {
        if(n%p[i]==0)
            return 0;
        qt*=p[i];
    }
    qt--;

    if(n<=qt)
        return checkprime(n); /* use another simplified function */

    if((q=calloc(qt, sizeof(unsigned long)))==NULL)
    {
        perror("q=calloc()");
        exit(1);
    }
    for(i=0; i<t; i++)
        for(j=p[i]-2; j<qt; j+=p[i])
            q[j]=1;

    for(j=0; j<qt; j++)
        if(q[j])
            rt++;

    rt=qt-rt;
    if((r=malloc(sizeof(unsigned long)*rt))==NULL)
    {
        perror("r=malloc()");
        exit(1);
    }
    i=0;
    for(j=0; j<qt; j++)
        if(!q[j])
            r[i++]=j+1;

    free(q);

    sq=ceil(sqrt(n));
    for(i=1; i<=sq; i+=qt+1)
    {
        if(i!=1 && n%i==0)
            return 0;
        for(j=0; j<rt; j++)
            if(n%(i+r[j])==0)
                return 0;
    }
    return 1;
}

I assume I did not optimize the code, but it's fair. Now, the tests. Because so many dynamic memory, I expected the list 2 3 5 to be a little slower than the 2 3 5 hard-coded. But it was ok as you can see bellow. After that, time got smaller and smaller, culminating the best list to be:

2 3 5 7 11 13 17 19

With 8.6 seconds. So if someone would create a hardcoded program that makes use of such technique I would suggest use the list 2 3 and 5, because the gain is not that big. But also, if willing to code, this list is ok. Problem is you cannot state all cases without a loop, or your code would be very big (There would be 1658879 ORs, that is || in the respective internal if). The next list:

2 3 5 7 11 13 17 19 23

time started to get bigger, with 13 seconds. Here the whole test:

1) JTable knows JCheckbox with built-in Boolean TableCellRenderers and TableCellEditor by default, then there is contraproductive declare something about that,

2) AbstractTableModel should be useful, where is in the JTable required to reduce/restrict/change nested and inherits methods by default implemented in the DefaultTableModel,

3) consider using DefaultTableModel, (if you are not sure about how to works) instead of AbstractTableModel,

could be generated from simple code:

import javax.swing.*;
import javax.swing.table.*;

public class TableCheckBox extends JFrame {

    private static final long serialVersionUID = 1L;
    private JTable table;

    public TableCheckBox() {
        Object[] columnNames = {"Type", "Company", "Shares", "Price", "Boolean"};
        Object[][] data = {
            {"Buy", "IBM", new Integer(1000), new Double(80.50), false},
            {"Sell", "MicroSoft", new Integer(2000), new Double(6.25), true},
            {"Sell", "Apple", new Integer(3000), new Double(7.35), true},
            {"Buy", "Nortel", new Integer(4000), new Double(20.00), false}
        };
        DefaultTableModel model = new DefaultTableModel(data, columnNames);
        table = new JTable(model) {

            private static final long serialVersionUID = 1L;

            /*@Override
            public Class getColumnClass(int column) {

                switch (column) {
                    case 0:
                        return String.class;
                    case 1:
                        return String.class;
                    case 2:
                        return Integer.class;
                    case 3:
                        return Double.class;
                    default:
                        return Boolean.class;
                }
            }
        };
        table.setPreferredScrollableViewportSize(table.getPreferredSize());
        JScrollPane scrollPane = new JScrollPane(table);
        getContentPane().add(scrollPane);
    }

    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {

            @Override
            public void run() {
                TableCheckBox frame = new TableCheckBox();
                frame.setDefaultCloseOperation(EXIT_ON_CLOSE);
                frame.pack();
                frame.setLocation(150, 150);
                frame.setVisible(true);
            }

Adding to @HYRY's answer in1d seems to be fastest for numpy. This is using numpy 1.8 and python 2.7.6.

In this test in1d was fastest, however 10 in a look cleaner:

a = arange(0,99999,3)
%timeit 10 in a
%timeit in1d(a, 10)

10000 loops, best of 3: 150 µs per loop
10000 loops, best of 3: 61.9 µs per loop

Constructing a set is slower than calling in1d, but checking if the value exists is a bit faster:

s = set(range(0, 99999, 3))
%timeit 10 in s

10000000 loops, best of 3: 47 ns per loop

Datatables have a .Select method, which returns a rows array according to the criteria you specify. Something like this:

Dim oRows() As DataRow

oRows = dtCountries.Select("CountryName = '" & userinput & "'")

If oRows.Count = 0 Then
   ' No rows found
Else
   ' At least one row found. Could be more than one
End If

Of course, if userinput contains ' character, it would raise an exception (like if you query the database). You should escape the ' characters (I use a function to do that).

If you use the new querySelectorAll you can call forEach directly.

document.querySelectorAll('.edit').forEach(function(button) {
    // Now do something with my button
});

Per the comment below. nodeLists do not have a forEach function.

If using this with babel you can add Array.from and it will convert non node lists to a forEach array. Array.from does not work natively in browsers below and including IE 11.

Array.from(document.querySelectorAll('.edit')).forEach(function(button) {
    // Now do something with my button
});

At our meetup last night I discovered another way to handle node lists not having forEach

[...document.querySelectorAll('.edit')].forEach(function(button) {
    // Now do something with my button
});

Browser Support for [...]

Change submit button:

<input id="submitButtonId" type="submit" value="Delete" />

With normal button:

<input id="submitButtonId" type="button" value="Delete" />

Then use click function:

$("#submitButtonId").click(function () {
        $('#submitButtonId').prop('disabled', true);
        $('#myForm').submit();
    });

And remember re-enable button when is necesary:

$('#submitButtonId').prop('disabled', false);

Use std::stringstream. Its operator << is overloaded for all built-in types.

#include <sstream>    

std::stringstream s;
s << "(" << c1 << "," << c2 << ")";
storedCorrect[count] = s.str();

This works like you'd expect - the same way you print to the screen with std::cout. You're simply "printing" to a string instead. The internals of operator << take care of making sure there's enough space and doing any necessary conversions (e.g., double to string).

Also, if you have the Boost library available, you might consider looking into lexical_cast. The syntax looks much like the normal C++-style casts:

#include <string>
#include <boost/lexical_cast.hpp>
using namespace boost;

storedCorrect[count] = "(" + lexical_cast<std::string>(c1) +
                       "," + lexical_cast<std::string>(c2) + ")";

Under the hood, boost::lexical_cast is basically doing the same thing we did with std::stringstream. A key advantage to using the Boost library is you can go the other way (e.g., string to double) just as easily. No more messing with atof() or strtod() and raw C-style strings.

UPDATE: For an arbitrary length of a nested dictionary, go to this answer.

Use the defaultdict function from the collections.

High performance: "if key not in dict" is very expensive when the data set is large.

Low maintenance: make the code more readable and can be easily extended.

from collections import defaultdict

target_dict = defaultdict(dict)
target_dict[key1][key2] = val

Here's the example from my code. So I will read a text from 1st line to 3rd line using readLine() and then store to array variable and print into textfield using for-loop :

QFile file("file.txt");

    if(!file.open(QIODevice::ReadOnly | QIODevice::Text))
        return;

    QTextStream in(&file);
    QString line[3] = in.readLine();
    for(int i=0; i<3; i++)
    {
        ui->textEdit->append(line[i]);
    }

You shouldn't use the control private tooltip, but the form one. This example works well:

public partial class Form1 : Form
{
    private System.Windows.Forms.ToolTip toolTip1;

    public Form1()
    {
        InitializeComponent();
        this.components = new System.ComponentModel.Container();
        this.toolTip1 = new System.Windows.Forms.ToolTip(this.components);

        MyRitchTextBox myRTB = new MyRitchTextBox();
        this.Controls.Add(myRTB);

        myRTB.Location = new Point(10, 10);
        myRTB.MouseEnter += new EventHandler(myRTB_MouseEnter);
        myRTB.MouseLeave += new EventHandler(myRTB_MouseLeave);
    }


    void myRTB_MouseEnter(object sender, EventArgs e)
    {
        MyRitchTextBox rtb = (sender as MyRitchTextBox);
        if (rtb != null)
        {
            this.toolTip1.Show("Hello!!!", rtb);
        }
    }

    void myRTB_MouseLeave(object sender, EventArgs e)
    {
        MyRitchTextBox rtb = (sender as MyRitchTextBox);
        if (rtb != null)
        {
            this.toolTip1.Hide(rtb);
        }
    }


    public class MyRitchTextBox : RichTextBox
    {
    }

}

Create a .htaccess file in directory and add this code to .htaccess file

AddHandler x-httpd-php .html .htm

or

AddType application/x-httpd-php .html .htm

It will force Apache server to parse HTML or HTM files as PHP Script

Try this one -

SELECT *
FROM ...
WHERE EXISTS(SELECT 1 
        FROM sys.columns c
        WHERE c.[object_id] = OBJECT_ID('dbo.Tags')
            AND c.name = 'ModifiedByUser'
    )

You say you've had problems with Navicat. For the record, I use Navicat and I haven't experienced the issue you describe. You might want to dig around, see if there's a reason for your problem and/or a solution, because given the question asked, my first recommendation would have been Navicat.

But if you want alternative suggestions, here are a few that I know of and have used:

MySQL has its own tool which you can download for free, called MySQL Workbench. Download it from here: http://wb.mysql.com/. My experience is that it's powerful, but I didn't really like the UI. But that's just my personal taste.

Another free program you might want to try is HeidiSQL. It's more similar to Navicat than MySQL Workbench. A colleague of mine loves it.

(interesting to note, by the way, that MariaDB (the forked version of MySQL) is currently shipped with HeidiSQL as its GUI tool)

Finally, if you're running a web server on your machine, there's always the option of a browser-based tool like PHPMyAdmin. It's actually a surprisingly powerful piece of software.

ps aux | grep node
kill -9 [PID] (provided by above command)

Description:

1. ps will give the process status, aux provide the list of a: all users processes, u: user own processes, x: all other processes not attached to terminal.
2. pipe symbol: | will pass the result of ps aux to manipulate further.
3. grep will search the string provided(node in our case) from the list provided by ps aux.

A blanket "no you shouldn't" is terrible advice. This is perfectly reasonable in many situations depending on your use case, workload, data entropy, hardware, etc.. What you shouldn't do is make assumptions.

It should be noted that you can specify a prefix which will limit MySQL's indexing, thereby giving you some help in narrowing down the results before scanning the rest. This may, however, become less useful over time as your prefix "fills up" and becomes less unique.

It's very simple to do, e.g.:

CREATE TABLE IF NOT EXISTS `foo` (
  `id` varchar(128),
  PRIMARY KEY (`id`(4))
)

Also note that the prefix (4) appears after the column quotes. Where the 4 means that it should use the first 4 characters of the 128 possible characters that can exist as the id.

Lastly, you should read how index prefixes work and their limitations before using them: https://dev.mysql.com/doc/refman/8.0/en/create-index.html

When I used CocoaPods to develop iOS projects, there is a .xcworkspace file, you need to open the project with .xcworkspace file related with CocoaPods.

But when you Show Package Contents with .xcworkspace file, you will find the contents.xcworkspacedata file.

<?xml version="1.0" encoding="UTF-8"?>
<Workspace
   version = "1.0">
   <FileRef
      location = "group:BluetoothColorLamp24G.xcodeproj">
   </FileRef>
   <FileRef
      location = "group:Pods/Pods.xcodeproj">
   </FileRef>
</Workspace>

pay attention to this line:

location = "group:BluetoothColorLamp24G.xcodeproj"

The .xcworkspace file has reference with the .xcodeproj file.

Development Environment:

macOS 10.14
Xcode 10.1

As of python 3.6 you can use Literal String Interpolation.

births = 5.25487

If there was a birth every 7 seconds, there would be: 5.25 births

All the answers above about reload() or imp.reload() are deprecated.

reload() is no longer a builtin function in python 3 and imp.reload() is marked deprecated (see help(imp)).

It's better to use importlib.reload() instead.

I used similar code to @MethodMan but I had to keep track of the data the serial port was sending and look for a terminating character to know when the serial port was done sending data.

private string buffer { get; set; }
private SerialPort _port { get; set; }

public Port() 
{
    _port = new SerialPort();
    _port.DataReceived += new SerialDataReceivedEventHandler(dataReceived);
    buffer = string.Empty;
}

private void dataReceived(object sender, SerialDataReceivedEventArgs e)
{    
    buffer += _port.ReadExisting();

    //test for termination character in buffer
    if (buffer.Contains("\r\n"))
    {
        //run code on data received from serial port
    }
}

Start thinking in terms of a: blast from the past

Once upon a time, long long ago, there lived in the land of computing interpreters and compilers. All kinds of fuss ensued over the merits of one over the other. The general opinion at that time was something along the lines of:

• Interpreter: Fast to develop (edit and run). Slow to execute because each statement had to be interpreted into machine code every time it was executed (think of what this meant for a loop executed thousands of times).
• Compiler: Slow to develop (edit, compile, link and run. The compile/link steps could take serious time). Fast to execute. The whole program was already in native machine code.

A one or two order of magnitude difference in the runtime performance existed between an interpreted program and a compiled program. Other distinguishing points, run-time mutability of the code for example, were also of some interest but the major distinction revolved around the run-time performance issues.

Today the landscape has evolved to such an extent that the compiled/interpreted distinction is pretty much irrelevant. Many compiled languages call upon run-time services that are not completely machine code based. Also, most interpreted languages are "compiled" into byte-code before execution. Byte-code interpreters can be very efficient and rival some compiler generated code from an execution speed point of view.

The classic difference is that compilers generated native machine code, interpreters read source code and generated machine code on the fly using some sort of run-time system. Today there are very few classic interpreters left - almost all of them compile into byte-code (or some other semi-compiled state) which then runs on a virtual "machine".

The Swift version from String to Data and back to String:

Xcode 10.1 • Swift 4.2.1

extension Data {
    var string: String? {
        return String(data: self, encoding: .utf8)
    }
}

extension StringProtocol {
    var data: Data {
        return Data(utf8)
    }
}

extension String {
    var base64Decoded: Data? {
        return Data(base64Encoded: self)
    }
}

I just found this question and answers as I am trying to do the same thing! I did not want to use some of the other tools mentioned. (Don't want to give my email away, and don't want to pay). I found that Inkscape (v0.91) can do a pretty good job. This tutorial is quick to and easy to understand.

Its as simple as selecting your bitmap in Inkskape and Shift+Alt+B.

Edit: Updated css to match with what you have..

DEMO

HTML

<div>
    <span class="close-btn"><a href="#">X</a></span>
</div>

CSS

.close-btn {
    border: 2px solid #c2c2c2;
    position: relative;
    padding: 1px 5px;
    top: -20px;
    background-color: #605F61;
    left: 198px;
    border-radius: 20px;
}

.close-btn a {
    font-size: 15px;
    font-weight: bold;
    color: white;
    text-decoration: none;
}

If you want to just "set" the actual filename, without incurring the overhead of loading and re-saving the file (!!), or resorting to using a charfield (!!!), you might want to try something like this --

model_instance.myfile = model_instance.myfile.field.attr_class(model_instance, model_instance.myfile.field, 'my-filename.jpg')

This will light up your model_instance.myfile.url and all the rest of them just as if you'd actually uploaded the file.

Like @t-stone says, what we really want, is to be able to set instance.myfile.path = 'my-filename.jpg', but Django doesn't currently support that.

From your original code it looks like what you want is to check if the list was empty:

var getResult= keyValueList.SingleOrDefault();
if (keyValueList.Count == 0)
{
   /* default */
}
else
{
}

Instead of concatenating the things together on your own, you could instead use the node.js API for URLs and pass URL.format() the informations from express.

Example:

var url = require('url');

function fullUrl(req) {
  return url.format({
    protocol: req.protocol,
    host: req.get('host'),
    pathname: req.originalUrl
  });
}

I'm would recommend it:

First i will give you Dangerous Permission List in Android M and Later version

Then give you example of how to request for permission in Android M and later version.

I ask user to WRITE_EXTERNAL_STORAGE permission.

First add permission in your android menifest file

Step 1 Declare requestcode

 private static String TAG = "PermissionDemo";
 private static final int REQUEST_WRITE_STORAGE = 112; 

Step 2 Add this code when you want ask user for permission

 //ask for the permission in android M
    int permission = ContextCompat.checkSelfPermission(this,
            Manifest.permission.WRITE_EXTERNAL_STORAGE);

    if (permission != PackageManager.PERMISSION_GRANTED) {
        Log.i(TAG, "Permission to record denied");

        if (ActivityCompat.shouldShowRequestPermissionRationale(this,
                Manifest.permission.WRITE_EXTERNAL_STORAGE)) {
            AlertDialog.Builder builder = new AlertDialog.Builder(this);
            builder.setMessage("Permission to access the SD-CARD is required for this app to Download PDF.")
                    .setTitle("Permission required");

            builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {

                public void onClick(DialogInterface dialog, int id) {
                    Log.i(TAG, "Clicked");
                    makeRequest();
                }
            });

            AlertDialog dialog = builder.create();
            dialog.show();

        } else {
            makeRequest();
        }
    }

    protected void makeRequest() {
        ActivityCompat.requestPermissions(this,
                new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE},
                REQUEST_WRITE_STORAGE);
    }

Step 3 Add override method for Request

 @Override
public void onRequestPermissionsResult(int requestCode,
                                       String permissions[], int[] grantResults) {
    switch (requestCode) {
        case REQUEST_WRITE_STORAGE: {

            if (grantResults.length == 0
                    || grantResults[0] !=
                    PackageManager.PERMISSION_GRANTED) {

                Log.i(TAG, "Permission has been denied by user");

            } else {

                Log.i(TAG, "Permission has been granted by user");

            }
            return;
        }
    }
}

Note: Do not forget to add permission in menifest file

Special Case for Configuration change

It is possible that the user will rotate the device or otherwise trigger a configuration change while our permission dialog is in the foreground. Since our activity is still visible behind that dialog, we get destroyed and recreated… but we do not want to re-raise the permission dialog again.

That is why we have a boolean, named isInPermission, that tracks whether or not we are in the middle of requesting permissions. We hold onto that value in onSaveInstanceState():

@Override
protected void onSaveInstanceState(Bundle outState) {
  super.onSaveInstanceState(outState);
  outState.putBoolean(STATE_IN_PERMISSION, isInPermission);
}

We restore it in onCreate(). If we do not hold all of the desired permissions, but isInPermission is true, we skip requesting the permissions, since we are in the middle of doing so already.

Crude way:

• At every node
  • X = find if either of the n1, n2 exist on the left side of the Node
  • Y = find if either of the n1, n2 exist on the right side of the Node
    • if the node itself is n1 || n2, we can call it either found on left or right for the purposes of generalization.
  • If both X and Y is true, then the Node is the CA

The problem with the method above is that we will be doing the "find" multiple times, i.e. there is a possibility of each node getting traversed multiple times. We can overcome this problem if we can record the information so as to not process it again (think dynamic programming).

So rather than doing find every node, we keep a record of as to whats already been found.

Better Way:

• We check to see if for a given node if left_set (meaning either n1 | n2 has been found in the left subtree) or right_set in a depth first fashion. (NOTE: We are giving the root itself the property of being left_set if it is either n1 | n2)
• If both left_set and right_set then the node is a LCA.

Code:

struct Node *
findCA(struct Node *root, struct Node *n1, struct Node *n2, int *set) {
   int left_set, right_set;
   left_set = right_set = 0;
   struct Node *leftCA, *rightCA;
   leftCA = rightCA = NULL;

   if (root == NULL) {
      return NULL;
   }
   if (root == n1 || root == n2) {
      left_set = 1;
      if (n1 == n2) {
         right_set = 1;
      }
   }

   if(!left_set) {
      leftCA = findCA(root->left, n1, n2, &left_set);
      if (leftCA) {
         return leftCA;
      }
   }
   if (!right_set) {
      rightCA= findCA(root->right, n1, n2, &right_set);
      if(rightCA) {
         return rightCA;
      }
   }

   if (left_set && right_set) {
      return root;
   } else {
      *set = (left_set || right_set);
      return NULL;
   }
}

In php.ini file

change this

;extension=php_mysql.dll

into

extension=php_mysql.dll

Another cause is accidentally putting the data=... inside the aes(...) instead of outside:

RIGHT:
ggplot(data=df[df$var7=='9-06',], aes(x=lifetime,y=rep_rate,group=mdcp,color=mdcp) ...)

WRONG:
ggplot(aes(data=df[df$var7=='9-06',],x=lifetime,y=rep_rate,group=mdcp,color=mdcp) ...)

In particular this can happen when you prototype your plot command with qplot(), which doesn't use an explicit aes(), then edit/copy-and-paste it into a ggplot()

qplot(data=..., x=...,y=..., ...)

ggplot(data=..., aes(x=...,y=...,...))

It's a pity ggplot's error message isn't Missing 'data' argument! instead of this cryptic nonsense, because that's what this message often means.

This is because in relational database terminology, what you want to do is not called "inserting", but "UPDATING" - you are updating an existing row's field from one value (NULL in your case) to "test"

UPDATE your_table SET table_column = "test" 
WHERE table_column = NULL 

You don't need the second line if you want to update 100% of rows.

I had this error in tests, the directive templateUrl wasn't trusted, but only for the spec, so I added the template directory:

beforeEach(angular.mock.module('app.templates'));

My main directory is app.

How about this other solution to keep the nice switch instead of an if-else:

private enum LayoutElement {
    NONE(-1),
    PLAY_BUTTON(R.id.playbtn),
    STOP_BUTTON(R.id.stopbtn),
    MENU_BUTTON(R.id.btnmenu);

    private static class _ {
        static SparseArray<LayoutElement> elements = new SparseArray<LayoutElement>();
    }

    LayoutElement(int id) {
        _.elements.put(id, this);
    }

    public static LayoutElement from(View view) {
        return _.elements.get(view.getId(), NONE);
    }

}

So in your code you can do this:

public void onClick(View src) {
    switch(LayoutElement.from(src)) {
    case PLAY_BUTTTON:
        checkwificonnection();
        break;

    case STOP_BUTTON:
        Log.d(TAG, "onClick: stopping srvice");
        Playbutton.setImageResource(R.drawable.playbtn1);
        Playbutton.setVisibility(0); //visible
        Stopbutton.setVisibility(4); //invisible
        stopService(new Intent(RakistaRadio.this,myservice.class));
        clearstatusbar();
        timer.cancel();
        Title.setText(" ");
        Artist.setText(" ");
        break;

    case MENU_BUTTON:
        openOptionsMenu();
        break;
    }
}

Enums are static so this will have very limited impact. The only window for concern would be the double lookup involved (first on the internal SparseArray and later on the switch table)

That said, this enum can also be utilised to fetch the items in a fluent manner, if needed by keeping a reference to the id... but that's a story for some other time.

Try using this, this worked fine for me.

json_encode(unserialize(serialize($array)));

This should do the trick:

$('#some_select_box').click(function() {
  $('option:selected', this ).remove();
});

You can't control the timeout due to UnknownHostException. These are DNS timings. You can only control the connect timeout given a valid host. None of the preceding answers addresses this point correctly.

But I find it hard to believe that you are really getting an UnknownHostException when you specify an IP address rather than a hostname.

EDIT To control Java's DNS timeouts see this answer.

UPDATE some_table 
   SET this_column=x, that_column=y 
   WHERE something LIKE 'them'

$('#dropdownid').empty();

That will remove all <option> elements underneath the dropdown element.

If you want to unselect selected items, go with the code from Russ.

For SQl Server the most efficient way is:

with
ids as ( --condition for split table into groups
    select i from (values (9),(12),(17),(18),(19),(20),(22),(21),(23),(10)) as v(i) 
) 
,src as ( 
    select * from yourTable where  <condition> --use this as filter for other conditions
)
,joined as (
    select tops.* from ids 
    cross apply --it`s like for each rows
    (
        select top(1) * 
        from src
        where CommodityId = ids.i 
    ) as tops
)
select * from joined

and don't forget to create clustered index for used columns

numpy.linspace() gives you a one-dimensional NumPy array. For example:

>>> my_array = numpy.linspace(1, 10, 10)
>>> my_array
array([  1.,   2.,   3.,   4.,   5.,   6.,   7.,   8.,   9.,  10.])

Therefore:

for index,point in my_array

cannot work. You would need some kind of two-dimensional array with two elements in the second dimension:

>>> two_d = numpy.array([[1, 2], [4, 5]])
>>> two_d
array([[1, 2], [4, 5]])

Now you can do this:

>>> for x, y in two_d:
    print(x, y)

1 2
4 5

Extending @Ryogi answer above, you can take advantage of the lower.tail parameter like so:

qt(0.25/2, 40, lower.tail = FALSE) # 75% confidence

qt(0.01/2, 40, lower.tail = FALSE) # 99% confidence

This script demonstrates a few ways to show the local timezone using astimezone():

#!/usr/bin/env python3

import pytz
from datetime import datetime, timezone
from tzlocal import get_localzone

utc_dt = datetime.now(timezone.utc)

PST = pytz.timezone('US/Pacific')
EST = pytz.timezone('US/Eastern')
JST = pytz.timezone('Asia/Tokyo')
NZST = pytz.timezone('Pacific/Auckland')

print("Pacific time {}".format(utc_dt.astimezone(PST).isoformat()))
print("Eastern time {}".format(utc_dt.astimezone(EST).isoformat()))
print("UTC time     {}".format(utc_dt.isoformat()))
print("Japan time   {}".format(utc_dt.astimezone(JST).isoformat()))

# Use astimezone() without an argument
print("Local time   {}".format(utc_dt.astimezone().isoformat()))

# Use tzlocal get_localzone
print("Local time   {}".format(utc_dt.astimezone(get_localzone()).isoformat()))

# Explicitly create a pytz timezone object
# Substitute a pytz.timezone object for your timezone
print("Local time   {}".format(utc_dt.astimezone(NZST).isoformat()))

It outputs the following:

$ ./timezones.py 
Pacific time 2019-02-22T17:54:14.957299-08:00
Eastern time 2019-02-22T20:54:14.957299-05:00
UTC time     2019-02-23T01:54:14.957299+00:00
Japan time   2019-02-23T10:54:14.957299+09:00
Local time   2019-02-23T14:54:14.957299+13:00
Local time   2019-02-23T14:54:14.957299+13:00
Local time   2019-02-23T14:54:14.957299+13:00

As of python 3.6 calling astimezone() without a timezone object defaults to the local zone (docs). This means you don't need to import tzlocal and can simply do the following:

#!/usr/bin/env python3

from datetime import datetime, timezone

utc_dt = datetime.now(timezone.utc)

print("Local time {}".format(utc_dt.astimezone().isoformat()))

Technically speaking the answer is correct, but there is a potential problem remaining. string test = rb.SelectedValue is an object and while this implicit cast works. It may not work correction if you were sending it to another method (and granted this may depend on the version of framework, I am unsure) it may not recognize the value.

string test = rb.SelectedValue;  //May work fine
SomeMethod(rb.SelectedValue);

where SomeMethod is expecting a string may not.

Sadly the rb.SelectedValue.ToString(); can save a few unexpected issues.

After some thinking i came up with this solution:

 LENGTHB(TO_CHAR(SUBSTR(<CLOB-Column>,1,4000)))

SUBSTR returns only the first 4000 characters (max string size)

TO_CHAR converts from CLOB to VARCHAR2

LENGTHB returns the length in Bytes used by the string.

Please note that you must install the driver for the version of your software client(MS access) not the version of the OS. that's mean that if your MS Access is a 32-bits version,you must install a 32-bit odbc driver. regards

On the Web API side, simply use Request object instead of creating new HttpRequestMessage

     var re = Request;
    var headers = re.Headers;

    if (headers.Contains("Custom"))
    {
        string token = headers.GetValues("Custom").First();
    }

    return null;

Output -

There's better support for this now through conda-env. You can, for example, now do:

name: sample_env
channels:
dependencies:
   - requests
   - bokeh>=0.10.0
   - pip:
     - "--editable=git+https://github.com/pythonforfacebook/facebook-sdk.git@8c0d34291aaafec00e02eaa71cc2a242790a0fcc#egg=facebook_sdk-master"

It's still calling pip under the covers, but you can now unify your conda and pip package specifications in a single environment.yml file.

If you wanted to update your root environment with this file, you would need to save this to a file (for example, environment.yml), then run the command: conda env update -f environment.yml.

It's more likely that you would want to create a new environment:

conda env create -f environment.yml (changed as supposed in the comments)

Below is an implementation I use to intercept each HTTP request before it goes out and the response which comes back. With this implementation, I also have a single point where I can pass any header value with the request.

public class HttpInterceptor implements ClientHttpRequestInterceptor {
private Logger logger = LoggerFactory.getLogger(this.getClass());
@Override
public ClientHttpResponse intercept(
        HttpRequest request, byte[] body,
        ClientHttpRequestExecution execution
) throws IOException {
    HttpHeaders headers = request.getHeaders();
    headers.add("Accept", MediaType.APPLICATION_JSON_UTF8_VALUE);
    headers.add("Content-Type", MediaType.APPLICATION_JSON_VALUE);
    traceRequest(request, body);
    ClientHttpResponse response = execution.execute(request, body);
    traceResponse(response);
    return response;
}

private void traceRequest(HttpRequest request, byte[] body) throws IOException {
    logger.info("===========================Request begin======================================");
    logger.info("URI         : {}", request.getURI());
    logger.info("Method      : {}", request.getMethod());
    logger.info("Headers     : {}", request.getHeaders() );
    logger.info("Request body: {}", new String(body, StandardCharsets.UTF_8));
    logger.info("==========================Request end=========================================");
}

private void traceResponse(ClientHttpResponse response) throws IOException {
    logger.info("============================Response begin====================================");
    logger.info("Status code  : {}", response.getStatusCode());
    logger.info("Status text  : {}", response.getStatusText());
    logger.info("Headers      : {}", response.getHeaders());
    logger.info("=======================Response end===========================================");
}}

None of these were working for me, couldn't delete or disconnect current users. Also couldn't see any active connections to the DB. Restarting SQL Server (Right click and select Restart) allowed me to do it.

Cookies and Sessions are used to store information. Cookies are only stored on the client-side machine, while sessions get stored on the client as well as a server.

Session

A session creates a file in a temporary directory on the server where registered session variables and their values are stored. This data will be available to all pages on the site during that visit.

A session ends when the user closes the browser or after leaving the site, the server will terminate the session after a predetermined period of time, commonly 30 minutes duration.

Cookies

Cookies are text files stored on the client computer and they are kept of use tracking purposes. The server script sends a set of cookies to the browser. For example name, age, or identification number, etc. The browser stores this information on a local machine for future use.

When the next time the browser sends any request to the web server then it sends those cookies information to the server and the server uses that information to identify the user.

One significant difference between INNER JOIN and NATURAL JOIN is the number of columns returned.

Consider:

TableA                           TableB
+------------+----------+        +--------------------+    
|Column1     | Column2  |        |Column1  |  Column3 |
+-----------------------+        +--------------------+
| 1          |  2       |        | 1       |   3      |
+------------+----------+        +---------+----------+

The INNER JOIN of TableA and TableB on Column1 will return

SELECT * FROM TableA AS a INNER JOIN TableB AS b USING (Column1);
SELECT * FROM TableA AS a INNER JOIN TableB AS b ON a.Column1 = b.Column1;

+------------+-----------+---------------------+    
| a.Column1  | a.Column2 | b.Column1| b.Column3|
+------------------------+---------------------+
| 1          |  2        | 1        |   3      |
+------------+-----------+----------+----------+

The NATURAL JOIN of TableA and TableB on Column1 will return:

SELECT * FROM TableA NATURAL JOIN TableB
+------------+----------+----------+    
|Column1     | Column2  | Column3  |
+-----------------------+----------+
| 1          |  2       |   3      |
+------------+----------+----------+

The repeated column is avoided.

(AFAICT from the standard grammar, you can't specify the joining columns in a natural join; the join is strictly name-based. See also Wikipedia.)

(There's a cheat in the inner join output; the a. and b. parts would not be in the column names; you'd just have column1, column2, column1, column3 as the headings.)

Normally, I would go with what the documentation says but if the instructor explicitly said to stick with JDK 6, I'd use JDK 6 because you would want your development environment to be as close as possible to the instructors. It would suck if you ran into an issue and having the thought in the back of your head that maybe it's because you're on JDK 7 that you're having the issue. Btw, I haven't touched Android recently but I personally never ran into issues when I was on JDK 7 but mind you, I only code Android apps casually.

I think (from experimenting - MSDN is unhelpful here) that there is no direct way of doing this. Setting Criteria1 to an Array is equivalent to using the tick boxes in the dropdown - as you say it will only filter a list based on items that match one of those in the array.

Interestingly, if you have the literal values "<>A" and "<>B" in the list and filter on these the macro recorder comes up with

Range.AutoFilter Field:=1, Criteria1:="=<>A", Operator:=xlOr, Criteria2:="=<>B"

which works. But if you then have the literal value "<>C" as well and you filter for all three (using tick boxes) while recording a macro, the macro recorder replicates precisely your code which then fails with an error. I guess I'd call that a bug - there are filters you can do using the UI which you can't do with VBA.

Anyway, back to your problem. It is possible to filter values not equal to some criteria, but only up to two values which doesn't work for you:

Range("$A$1:$A$9").AutoFilter Field:=1, Criteria1:="<>A", Criteria2:="<>B", Operator:=xlAnd

There are a couple of workarounds possible depending on the exact problem:

1. Use a "helper column" with a formula in column B and then filter on that - e.g. =ISNUMBER(A2) or =NOT(A2="A", A2="B", A2="C") then filter on TRUE
2. If you can't add a column, use autofilter with Criteria1:=">-65535" (or a suitable number lower than any you expect) which will filter out non-numeric values - assuming this is what you want
3. Write a VBA sub to hide rows (not exactly the same as an autofilter but it may suffice depending on your needs).

For example:

Public Sub hideABCRows(rangeToFilter As Range)
  Dim oCurrentCell As Range
  On Error GoTo errHandler

  Application.ScreenUpdating = False
  For Each oCurrentCell In rangeToFilter.Cells
    If oCurrentCell.Value = "A" Or oCurrentCell.Value = "B" Or oCurrentCell.Value = "C" Then
      oCurrentCell.EntireRow.Hidden = True
    End If
  Next oCurrentCell

  Application.ScreenUpdating = True
  Exit Sub

errHandler:
    Application.ScreenUpdating = True
End Sub

In my case, was an environment variable GIT_DIR, which I added to access faster.

This also broke all my local repos in SourceTree :(

Considering

$string="We have www/audio path where the audio files are stored";  //Considering the string like this

Either you can use

strstr($string, 'www/audio');

Or

$expStr=explode("www/audio",$string);
$resultString="www/audio".$expStr[1];

You need to make both your method - printMenu() and getUserChoice() static, as you are directly invoking them from your static main method, without creating an instance of the class, those methods are defined in. And you cannot invoke a non-static method without any reference to an instance of the class they are defined in.

Alternatively you can change the method invocation part to:

BookStoreApp2 bookStoreApp = new BookStoreApp2();
bookStoreApp.printMenu();
bookStoreApp.getUserChoice();

the following is that the difference between iterator and listIterator

iterator :

boolean hasNext();
E next();
void remove();

listIterator:

boolean hasNext();
E next();
boolean hasPrevious();
E previous();
int nextIndex();
int previousIndex();
void remove();
void set(E e);
void add(E e);

Using the C# language constructs, you cannot explicitly call the base function from outside the scope of A or B. If you really need to do that, then there is a flaw in your design - i.e. that function shouldn't be virtual to begin with, or part of the base function should be extracted to a separate non-virtual function.

You can from inside B.X however call A.X

class B : A
{
  override void X() { 
    base.X();
    Console.WriteLine("y"); 
  }
}

But that's something else.

As Sasha Truf points out in this answer, you can do it through IL. You can probably also accomplish it through reflection, as mhand points out in the comments.

Are you ssh'ing to a directory that's inside your work tree? If the root of your ssh mount point doesn't include the .git dir, then zsh won't be able to find git info. Make sure you're mounting something that includes the root of the repo.

As for GIT_DISCOVERY_ACROSS_FILESYSTEM, it doesn't do what you want. Git by default will stop at a filesystem boundary. If you turn that on (and it's just an env var), then git will cross the filesystem boundary and keep looking. However, that's almost never useful, because you'd be implying that you have a .git directory on your local machine that's somehow meant to manage a work tree that's comprised partially of an sshfs mount. That doesn't make much sense.

Python 3

mydict = {'a': 'one', 'b': 'two', 'c': 'three'}
mykeys = [*mydict]          #list of keys
myvals = [*mydict.values()] #list of values

print(mykeys)
print(myvals)

Output

['a', 'b', 'c']
['one', 'two', 'three']

You can fetch the list of tables and schemata by querying the SQLITE_MASTER table:

sqlite> .tab
job         snmptarget  t1          t2          t3        
sqlite> select name from sqlite_master where type = 'table';
job
t1
t2
snmptarget
t3

sqlite> .schema job
CREATE TABLE job (
    id INTEGER PRIMARY KEY,
    data VARCHAR
);
sqlite> select sql from sqlite_master where type = 'table' and name = 'job';
CREATE TABLE job (
    id INTEGER PRIMARY KEY,
    data VARCHAR
)

  <?php
      $items = DB::table('course')->get()->pluck('name','id');
      $selectID = 3;
  ?>

  <div class="form-group">
   {{ Form::label('course_title', 'Course Title') }}
   {!! Form::select('myselect', $items, $select, ['class' => 'form-control']) !!}
  </div>

This show similar types of following options :

<select name="myselect" id="myselect">
 <option value="1">Computer Introduction</option>
 <option value="2">Machine Learning</option>
 <option value="3" selected='selected'>Python Programming</option>
 <option value="4">Networking Fundamentals</option>
 .
 .
 .
 .  
</select>

ULs don't have a name attribute, but you can reference the ul by tag name.

Try replacing line 3 in your script with this:

var sub = cat.getElementsByTagName("UL");

Note that the way the git credential helper "store" will store the unencrypted passwords changes with Git 2.5+ (Q2 2014).
See commit 17c7f4d by Junio C Hamano (gitster)

credential-xdg

Tweak the sample "store" backend of the credential helper to honor XDG configuration file locations when specified.

The doc now say:

If not specified:

• credentials will be searched for from ~/.git-credentials and $XDG_CONFIG_HOME/git/credentials, and
• credentials will be written to ~/.git-credentials if it exists, or $XDG_CONFIG_HOME/git/credentials if it exists and the former does not.

Try =Year(Now()) and format the cell as General.

For SQL Server 2005 and above use Coalesce for nulls and I am using Cast or Convert if there are numeric values -

declare @CodeNameString  nvarchar(max)
select  @CodeNameString = COALESCE(@CodeNameString + ',', '')  + Cast(CodeName as varchar) from AccountCodes  ORDER BY Sort
select  @CodeNameString

All inputs should be replaced with custom directive that reads a single global variable to toggle readonly status.

// template
<your-input [readonly]="!childmessage"></your-input>

// component value
childmessage = false;

Another approach in spark 2.1.0 is to use --conf spark.driver.userClassPathFirst=true during spark-submit which changes the priority of dependency load, and thus the behavior of the spark-job, by giving priority to the jars the user is adding to the class-path with the --jars option.

First open a console then cd to where you've downloaded your file like some-package.whl and use

pip install some-package.whl

Note: if pip.exe is not recognized, you may find it in the "Scripts" directory from where python has been installed. I have multiple Python installations, and needed to use the pip associated with Python 3 to install a version 3 wheel.

If pip is not installed, and you are using Windows: How to install pip on Windows?

Here is simple example. A contact has one to many associated phone numbers. When a contact is deleted, I want all its associated phone numbers to also be deleted, so I use ON DELETE CASCADE. The one-to-many/many-to-one relationship is implemented with by the foreign key in the phone_numbers.

CREATE TABLE contacts
 (contact_id BIGINT AUTO_INCREMENT NOT NULL,
 name VARCHAR(75) NOT NULL,
 PRIMARY KEY(contact_id)) ENGINE = InnoDB;

CREATE TABLE phone_numbers
 (phone_id BIGINT AUTO_INCREMENT NOT NULL,
  phone_number CHAR(10) NOT NULL,
 contact_id BIGINT NOT NULL,
 PRIMARY KEY(phone_id),
 UNIQUE(phone_number)) ENGINE = InnoDB;

ALTER TABLE phone_numbers ADD FOREIGN KEY (contact_id) REFERENCES \
contacts(contact_id) ) ON DELETE CASCADE;

By adding "ON DELETE CASCADE" to the foreign key constraint, phone_numbers will automatically be deleted when their associated contact is deleted.

INSERT INTO table contacts(name) VALUES('Robert Smith');
INSERT INTO table phone_numbers(phone_number, contact_id) VALUES('8963333333', 1);
INSERT INTO table phone_numbers(phone_number, contact_id) VALUES('8964444444', 1);

Now when a row in the contacts table is deleted, all its associated phone_numbers rows will automatically be deleted.

DELETE TABLE contacts as c WHERE c.id=1; /* delete cascades to phone_numbers */

To achieve the same thing in Doctrine, to get the same DB-level "ON DELETE CASCADE" behavoir, you configure the @JoinColumn with the onDelete="CASCADE" option.

To write a script that is secure to be run as either a shell script or sourced as an rc file, the script can check and compare $0 and $BASH_SOURCE and determine if exit can be safely used.

Here is a short code snippet for that

[ "X$(basename $0)" = "X$(basename $BASH_SOURCE)" ] && \
    echo "***** executing $name_src as a shell script *****" || \
    echo "..... sourcing $name_src ....."

The simplest solution would be a correlated sub select:

select
    A.*
from
    table_A A
where
    A.id in (
        select B.id from table_B B where B.tag = 'chair'
)

Alternatively you could join the tables and filter the rows you want:

select
    A.*
from
    table_A A
inner join table_B B
    on A.id = B.id
where
    B.tag = 'chair'

You should profile both and see which is faster on your dataset.

I had a similar problem. GET requests worked and their (empty) request bodies got written to the the log file. POST requests failed with a 404. Experimenting a bit, I found that all POST requests were failing. I found a forum posting asking about POST requests and the solution there worked for me. That solution? Add a proxy_header line right before the proxy_pass line, exactly like the one in the example below.

server {
    listen       192.168.0.1:45080;
    server_name  foo.example.org;

    access_log  /path/to/log/nginx/post_bodies.log post_bodies;
    location / {
      ### add the following proxy_header line to get POSTs to work
      proxy_set_header Host $http_host;
      proxy_pass   http://10.1.2.3;
    }
}

(This is with nginx 1.2.1 for what it is worth.)

As described by javafuns here, this is an example:

public abstract class TestEngine
{
   private String engineId;
   private String engineName;

   public TestEngine(String engineId , String engineName)
   {
     this.engineId = engineId;
     this.engineName = engineName;
   }
   //public gettors and settors
   public abstract void scheduleTest();
}


public class JavaTestEngine extends TestEngine
{

   private String typeName;

   public JavaTestEngine(String engineId , String engineName , String typeName)
   {
      super(engineId , engineName);
      this.typeName = typeName;
   }

   public void scheduleTest()
   {
     //do Stuff
   }
}

You can use two max function. Let's say get data of userid=10 and its 2nd highest salary from SALARY_TBL.

select max(salary) from SALARY_TBL
where 
userid=10
salary <> (select max(salary) from SALARY_TBL where userid=10)

You could try:

<a href="<?php echo $directory ?>">The link to the file</a>

Or for PHP 5.4+ (<?= is the PHP short echo tag):

<a href="<?= $directory ?>">The link to the file</a>

But your path is relative to the server, don't forget that.

I am using a Mac. I had the same problem wherein .csv file was in the same folder where the python script was placed, however, Spyder still was unable to locate the file. I changed the file name from capital letters to all small letters and it worked.

i don't know of a simple css(2.1 standard)-only solution for circles, but for squares you can do easily:

.squared {
    border: 2x solid black;
}

then, use the following html code:

<img src="…" alt="an image " class="squared" />

    public static function normalizeUrl(string $url) {
        $parts = parse_url($url);
        return $parts['scheme'] .
            '://' .
            $parts['host'] .
            implode('/', array_map('rawurlencode', explode('/', $parts['path'])));

    }

You can just use top It will display everything running on your OSX

I think you can adapt the function to substract the two timestamps:

return  EXTRACT(MINUTE FROM 
  TO_TIMESTAMP(to_char(p_date1,'DD-MON-YYYY HH:MI:SS'),'DD-MON-YYYY HH24:MI:SS')
-
  TO_TIMESTAMP(to_char(p_date2,'DD-MON-YYYY HH:MI:SS'),'DD-MON-YYYY HH24:MI:SS')
);

I think you could simplify it by just using CAST(p_date as TIMESTAMP).

return  EXTRACT(MINUTE FROM cast(p_date1 as TIMESTAMP) - cast(p_date2 as TIMESTAMP));

Remember dates and timestamps are big ugly numbers inside Oracle, not what we see in the screen; we don't need to tell him how to read them. Also remember timestamps can have a timezone defined; not in this case.

When I tried the other solutions I got this error:

var i = document.createElement("input"); //input element, text
i.setAttribute('type',"text");

var s = document.createElement("input"); //input element, Submit button
s.setAttribute('type',"submit");
s.setAttribute('value',"Submit");

f.appendChild(s);

//and some more input elements here
//and dont forget to add a submit button

If you want to avoid having to use a form or an input and you're looking for a button-looking link, you can create good-looking button links with a div wrapper, an anchor and an h1 tag. You'd potentially want this so you can freely place the link-button around your page. This is especially useful for horizontally centering buttons and having vertically-centered text inside of them. Here's how:

Your button will be comprised of three nested pieces: a div wrapper, an anchor, and an h1, like so:

.link-button-wrapper {_x000D_
    width: 200px;_x000D_
    height: 40px;_x000D_

        <h1>Button!</h1>_x000D_
    </a>_x000D_
</div>

Here's a jsFiddle to check it out and play around with it.

Benefits of this setup: 1. Making the div wrapper display: block makes it easy to center (using margin: 0 auto) and position (while an <a> is inline and harder to positionand not possible to center).

2. You could just make the <a> display:block, move it around, and style it as a button, but then vertically aligning text inside of it becomes hard.

3. This allows you to make the <a> display: inline-table and the <h1> display: table-cell, which allows you to use vertical-align: middle on the <h1> and center it vertically (which is always nice on a button). Yes, you could use padding, but if you want your button to dynamically resize, that won't be as clean.

4. Sometimes when you embed an <a> within a div, only the text is clickable, this setup makes the whole button clickable.

5. You don't have to deal with forms if you're just trying to move to another page. Forms are meant for inputting information, and they should be reserved for that.

6. Allows you to cleanly separte the button styling and text styling from each other (stretch advantage? Sure, but CSS can get nasty-looking so it's nice to decompose it).

It definitely made my life easier styling a mobile website for variable-sized screens.

It happens because you have not installed the minSdkVersion or targetSdkVersion in you’re computer. I've tested it right now.

For example, if you have those lines in your Manifest.xml:

<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="17" />

And you have installed only the API17 in your computer, it will report you an error. If you want to test it, try installing the other API version (in this case, API 8).

Even so, it's not an important error. It doesn't mean that your app is wrong.

Sorry about my expression. English is not my language. Bye!

I usually use numpy sum over the logical condition column:

>>> import numpy as np
>>> import pandas as pd
>>> df = pd.DataFrame({'Age' : [20,24,18,5,78]})
>>> np.sum(df['Age'] > 20)
2

This seems to me slightly shorter than the solution presented above

to set unlimited number of rows use

None

i.e.,

pd.set_option('display.max_cols', None)

now the notebook will display all the rows in all datasets within the notebook ;)

Similarly you can set to show all columns as

pd.set_option('display.max_rows', None)

now if you use run the cell with only dataframe with out any head or tail tags as

df

then it will show all the rows and columns in the dataframe df

do while in an exit control loop. while is an entry control loop.

There is an easier way

DROP TABLE IF EXISTS table_name;

It turns out that a FTP download call using winscp as last thing to do in the batch caused the problem. After inserting the echo command it works fine. Guess the problems source could be the winscp.exe which do not correctly report the end of the current task to the OS.

del "C:\_ftpcrawler\Account Export.csv" /S /Q

"C:\Program Files (x86)\WinSCP\WinSCP.exe" /console /script="C:\_isource\scripte\data.txt"

echo Download ausgeführt am %date%%time% >> C:\_isource\scripte\data.log

Adding an answer related to child_process.exec as I too had needed live feedback and wasn't getting any until after the script finished. This also supplements my comment to the accepted answer, but as it's formatted it will a bit more understandable and easier to read.

Basically, I have a npm script that calls Gulp, invoking a task which subsequently uses child_process.exec to execute a bash or batch script depending on the OS. Either script runs a build process via Gulp and then makes some calls to some binaries that work with the Gulp output.

It's exactly like the others (spawn, etc.), but for the sake of completion, here's exactly how to do it:

// INCLUDES
import * as childProcess from 'child_process'; // ES6 Syntax


// GLOBALS
let exec = childProcess.exec; // Or use 'var' for more proper 
                              // semantics, though 'let' is 
                              // true-to-scope


// Assign exec to a variable, or chain stdout at the end of the call
// to exec - the choice, yours (i.e. exec( ... ).stdout.on( ... ); )
let childProcess = exec
(
    './binary command -- --argument argumentValue',
    ( error, stdout, stderr ) =>
    {
        if( error )
        {
            // This won't show up until the process completes:
            console.log( '[ERROR]: "' + error.name + '" - ' + error.message );
            console.log( '[STACK]: ' + error.stack );

            console.log( stdout );
            console.log( stderr );
            callback();            // Gulp stuff
            return;
        }

        // Neither will this:
        console.log( stdout );
        console.log( stderr );
        callback();                // Gulp stuff
    }
);

Now its as simple as adding an event listener. For stdout:

childProcess.stdout.on
(
    'data',
    ( data ) =>
    {
        // This will render 'live':
        console.log( '[STDOUT]: ' + data );
    }
);

And for stderr:

childProcess.stderr.on
(
    'data',
    ( data ) =>
    {
        // This will render 'live' too:
        console.log( '[STDERR]: ' + data );
    }
);

Not too bad at all - HTH

Joins can only be used when there is an association between entities. Your Employee entity should not have a field named id_team, of type int, mapped to a column. It should have a ManyToOne association with the Team entity, mapped as a JoinColumn:

@ManyToOne
@JoinColumn(name="ID_TEAM")
private Team team;

Then, the following query will work flawlessly:

select e from Employee e inner join e.team

Which will load all the employees, except those that aren't associated to any team.

The same goes for all the other fields which are a foreign key to some other table mapped as an entity, of course (id_boss, id_profession).

It's time for you to read the Hibernate documentation, because you missed an extremely important part of what it is and how it works.

Please try this:

CREATE TABLE article (
  article_id bigint(20) NOT NULL serial,
  article_name varchar(20) NOT NULL,
  article_desc text NOT NULL,
  date_added datetime default NULL,
  PRIMARY KEY (article_id)
);

Put the textarea to a form, naming them, and just use the DOM objects easily, like this:

<body onload="form1.box.value = 'Welcome!'">
  <form name="form1">
    <textarea name="box"></textarea>
  </form>
</body>

    /** Creates new form Java Program1*/
    public Java Program1() 


    Image im = null;
    try {
    im = ImageIO.read(getClass().getResource("/image location"));
    } catch (IOException ex) {
    Logger.getLogger(chat.class.getName()).log(Level.SEVERE, null, ex);
    }
    setIconImage(im);

This is what I used in the GUI in netbeans and it worked perfectly

I'd aditionally recommend putting the output of var_dump() or printr into a pre tag when outputting to a browser.

print "<pre>";
print_r($dataset);
print "</pre>";

Will give a more readable result.

My preference, and I have no idea why this isn't already in jQuery:

$.fn.orElse = function(elseFunction) {
  if (!this.length) {
    elseFunction();
  }
};

Used like this:

$('#notAnElement').each(function () {
  alert("Wrong, it is an element")
}).orElse(function() {
  alert("Yup, it's not an element")
});

Or, as it looks in CoffeeScript:

$('#notAnElement').each ->
  alert "Wrong, it is an element"; return
.orElse ->
  alert "Yup, it's not an element"

My solution, using a SwitchCompat and Kotlin. In my situation, i needed to react to a change only if the user triggered it through the UI. In fact, my switch reacts to a LiveData, and this made both setOnClickListener and setOnCheckedChangeListener unusable. setOnClickListener in fact reacts correctly to user interaction, but it's not triggered if the user drags the thumb across the switch. setOnCheckedChangeListener on the other end is triggered also if the switch is toggled programmatically (for example by an observer). Now in my case the switch was present on two fragments, and so onRestoreInstanceState would trigger in some cases the switch with an old value overwriting the correct value.

So, i looked at the code of SwitchCompat, and was able to mimic it's behaviour successfully in distinguishing click and drag and used that to build a custom touchlistener that works as it should. Here we go:

/**
 * This function calls the lambda function passed with the right value of isChecked
 * when the switch is tapped with single click isChecked is relative to the current position so we pass !isChecked
 * when the switch is dragged instead, the position of the thumb centre where the user leaves the
 * thumb is compared to the middle of the switch, and we assume that left means false, right means true
 * (there is no rtl or vertical switch management)
 * The behaviour is extrapolated from the SwitchCompat source code
 */
class SwitchCompatTouchListener(private val v: SwitchCompat, private val lambda: (Boolean)->Unit) :  View.OnTouchListener {
    companion object {
        private const val TOUCH_MODE_IDLE = 0
        private const val TOUCH_MODE_DOWN = 1
        private const val TOUCH_MODE_DRAGGING = 2
    }

    private val vc = ViewConfiguration.get(v.context)
    private val mScaledTouchSlop = vc.scaledTouchSlop
    private var mTouchMode = 0
    private var mTouchX = 0f
    private var mTouchY = 0f

    /**
     * @return true if (x, y) is within the target area of the switch thumb
     * x,y and rect are in view coordinates, 0,0 is top left of the view
     */
    private fun hitThumb(x: Float, y: Float): Boolean {
        val rect = v.thumbDrawable.bounds
        return x >= rect.left && x <= rect.right && y >= rect.top && y <= rect.bottom
    }

    override fun onTouch(view: View, event: MotionEvent): Boolean {
        if (view == v) {
            when (MotionEventCompat.getActionMasked(event)) {
                MotionEvent.ACTION_DOWN -> {
                    val x = event.x
                    val y = event.y
                    if (v.isEnabled && hitThumb(x, y)) {
                        mTouchMode = TOUCH_MODE_DOWN;
                        mTouchX = x;
                        mTouchY = y;
                    }
                }
                MotionEvent.ACTION_MOVE -> {
                    val x = event.x
                    val y = event.y
                    if (mTouchMode == TOUCH_MODE_DOWN &&
                        (abs(x - mTouchX) > mScaledTouchSlop || abs(y - mTouchY) > mScaledTouchSlop)
                    )
                        mTouchMode = TOUCH_MODE_DRAGGING;
                }
                MotionEvent.ACTION_UP,
                MotionEvent.ACTION_CANCEL -> {
                    if (mTouchMode == TOUCH_MODE_DRAGGING) {
                        val r = v.thumbDrawable.bounds
                        if (r.left + r.right < v.width) lambda(false)
                        else lambda(true)
                    } else lambda(!v.isChecked)
                    mTouchMode = TOUCH_MODE_IDLE;
                }
            }
        }
        return v.onTouchEvent(event)
    }
}

How to use it:

the actual touch listener that accepts a lambda with the code to execute:

myswitch.setOnTouchListener(
    SwitchCompatTouchListener(myswitch) {
        // here goes all the code for your callback, in my case
        // i called a service which, when successful, in turn would 
        // update my liveData 
        viewModel.sendCommandToMyService(it) 
    }
)

For the sake of completeness, this is how the observer for the state switchstate (if you have it) looked like:

switchstate.observe(this, Observer {
    myswitch.isChecked = it
})

You can send mail from localhost with sendmail package , sendmail package is inbuild in XAMPP. So if you are using XAMPP then you can easily send mail from localhost.

for example you can configure C:\xampp\php\php.ini and c:\xampp\sendmail\sendmail.ini for gmail to send mail.

in C:\xampp\php\php.ini find extension=php_openssl.dll and remove the semicolon from the beginning of that line to make SSL working for gmail for localhost.

in php.ini file find [mail function] and change

SMTP=smtp.gmail.com
smtp_port=587
sendmail_from = [email protected]
sendmail_path = "\"C:\xampp\sendmail\sendmail.exe\" -t"

Now Open C:\xampp\sendmail\sendmail.ini. Replace all the existing code in sendmail.ini with following code

[sendmail]

smtp_server=smtp.gmail.com
smtp_port=587
error_logfile=error.log
debug_logfile=debug.log
[email protected]
auth_password=my-gmail-password
[email protected]

Now you have done!! create php file with mail function and send mail from localhost.

PS: don't forgot to replace my-gmail-id and my-gmail-password in above code. Also, don't forget to remove duplicate keys if you copied settings from above. For example comment following line if there is another sendmail_path : sendmail_path="C:\xampp\mailtodisk\mailtodisk.exe" in the php.ini file

Also remember to restart the server using the XAMMP control panel so the changes take effect.

For gmail please check https://support.google.com/accounts/answer/6010255 to allow access from less secure apps.

To send email on Linux (with sendmail package) through Gmail from localhost please check PHP+Ubuntu Send email using gmail form localhost.

Just use puttygen and load your private key into it. It offers different options, e.g. exporting the corresponding public key.

You can minimize the command prompt on during the run but you'll need two additional scripts: windowMode and getCmdPid.bat:

@echo off

call getCmdPid
call windowMode -pid %errorlevel% -mode minimized

cd /d C:\leads\ssh 
call C:\Ruby192\bin\setrbvars.bat
ruby C:\leads\ssh\put_leads.rb

You can also use OpenCV's inbuilt functions cv2.hconcat and cv2.vconcat which like their names suggest are used to join images horizontally and vertically respectively.

import cv2

img1 = cv2.imread('opencv/lena.jpg')
img2 = cv2.imread('opencv/baboon.jpg')

v_img = cv2.vconcat([img1, img2])
h_img = cv2.hconcat([img1, img2])

cv2.imshow('Horizontal', h_img)
cv2.imshow('Vertical', v_img)
cv2.waitKey(0)
cv2.destroyAllWindows()

Horizontal Concatenation

Vertical Concatenation

All C++ compilers have one serious performance problem to deal with. Compiling C++ code is a long, slow process.

Compiling headers included on top of C++ files is a very long, slow process. Compiling the huge header structures that form part of Windows API and other large API libraries is a very, very long, slow process. To have to do it over, and over, and over for every single Cpp source file is a death knell.

This is not unique to Windows but an old problem faced by all compilers that have to compile against a large API like Windows.

The Microsoft compiler can ameliorate this problem with a simple trick called precompiled headers. The trick is pretty slick: although every CPP file can potentially and legally give a sligthly different meaning to the chain of header files included on top of each Cpp file (by things like having different macros #define'd in advance of the includes, or by including the headers in different order), that is most often not the case. Most of the time, we have dozens or hundreds of included files, but they all are intended to have the same meaning for all the Cpp files being compiled in your application.

The compiler can make huge time savings if it doesn't have to start to compile every Cpp file plus its dozens of includes literally from scratch every time.

The trick consists of designating a special header file as the starting point of all compilation chains, the so called 'precompiled header' file, which is commonly a file named stdafx.h simply for historical reasons.

Simply list all your big huge headers for your APIs in your stdafx.h file, in the appropriate order, and then start each of your CPP files at the very top with an #include "stdafx.h", before any meaningful content (just about the only thing allowed before is comments).

Under those conditions, instead of starting from scratch, the compiler starts compiling from the already saved results of compiling everything in stdafx.h.

I don't believe that this trick is unique to Microsoft compilers, nor do I think it was an original development.

For Microsoft compilers, the setting that controls the use of precompiled headers is controlled by a command line argument to the compiler: /Yu "stdafx.h". As you can imagine, the use of the stdafx.h file name is simply a convention; you can change the name if you so wish.

In Visual Studio 2010, this setting is controlled from the GUI via Right-clicking on a CPP Project, selecting 'Properties' and navigating to "Configuration Properties\C/C++\Precompiled Headers". For other versions of Visual Studio, the location in the GUI will be different.

Note that if you disable precompiled headers (or run your project through a tool that doesn't support them), it doesn't make your program illegal; it simply means that your tool will compile everything from scratch every time.

If you are creating a library with no Windows dependencies, you can easily comment out or remove #includes from the stdafx.h file. There is no need to remove the file per se, but clearly you may do so as well, by disabling the precompile header setting above.

And in clean javascript:

var texts = [], lis = document.getElementsByTagName("li");
for(var i=0, im=lis.length; im>i; i++)
  texts.push(lis[i].firstChild.nodeValue);

alert(texts);

In addition to the example given in the Advanced Bash Scripting Guide referenced by Jefromi, these examples show how pipes create subshells:

$ echo $$ $BASHPID | cat -
11656 31528
$ echo $$ $BASHPID
11656 11656
$ echo $$ | while read line; do echo $line $$ $BASHPID; done
11656 11656 31497
$ while read line; do echo $line $$ $BASHPID; done <<< $$
11656 11656 11656

try this

$ cmd='mysql AMORE -u root --password="password" -h localhost -e "select host from amoreconfig"'
$ eval $cmd

assertNotNull asserts that the object is not null. If it is null the test fails, so you want that.

When you do valueForKey: you need to give it an NSString, whereas objectForKey: can take any NSObject subclass as a key. This is because for Key-Value Coding, the keys are always strings.

In fact, the documentation states that even when you give valueForKey: an NSString, it will invoke objectForKey: anyway unless the string starts with an @, in which case it invokes [super valueForKey:], which may call valueForUndefinedKey: which may raise an exception.

var lastname = "Hi";

if(typeof lastname !== "undefined")
{
  alert("Hi. Variable is defined.");
} 

If you need input from termial, try this

lc=`echo -n "xxx_${yyy}_iOS" |  base64`

-n option will not input "\n" character to base64 command.

You are inside a namespace so you should use \Exception to specify the global namespace:

try {

  $this->buildXMLHeader();

} catch (\Exception $e) {

    return $e->getMessage();
}

In your code you've used catch (Exception $e) so Exception is being searched in/as:

App\Services\PayUService\Exception

Since there is no Exception class inside App\Services\PayUService so it's not being triggered. Alternatively, you can use a use statement at the top of your class like use Exception; and then you can use catch (Exception $e).

Your app is crashing at:

welcomePlayer.setText("Welcome Back, " + String.valueOf(mPlayer.getName(this)) + " !");

because mPlayer=null.

You forgot to initialize Player mPlayer in your PlayGame Activity.

mPlayer = new Player(context,"");

ORDER BY column1 DESC, column2

This sorts everything by column1 (descending) first, and then by column2 (ascending, which is the default) whenever the column1 fields for two or more rows are equal.

MongoDB has a distinct command which returns an array of distinct values for a field; you can check the length of the array for a count.

There is a shell db.collection.distinct() helper as well:

> db.countries.distinct('country');
[ "Spain", "England", "France", "Australia" ]

> db.countries.distinct('country').length

I used the method below which really is a conundrum of all the ones above. I also found that onOptionsItemSelected is never activated.

    mDrawerToggle.setDrawerIndicatorEnabled(false);
    getSupportActionBar().setHomeButtonEnabled(true);

    Toolbar toolbar = (Toolbar) findViewById(R.id.tool_bar);
    if (toolbar != null) {
        toolbar.setNavigationOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                onBackPressed();
            }
        });
    }

if (android.os.Build.VERSION.SDK_INT < Build.VERSION_CODES.JELLY_BEAN)
     layout.setBackgroundDrawable(getResources().getDrawable(R.drawable.ready));
else if(android.os.Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP_MR1)
     layout.setBackground(getResources().getDrawable(R.drawable.ready));
else
     layout.setBackground(ContextCompat.getDrawable(this, R.drawable.ready));

I think there is another reason for wanting to set java.library.path. Subversion comes with many libraries and Eclipse won't see these unless java.library.path can be appended. For example I'm on OS-X, so the libraries are under \opt\subversion\lib. There are a lot of them and I'd like to keep them where they are (not copy them into a standard lib directory).

Project settings won't fix this.

Rather than locks, I suggest you look at long-running transactions, using v$transaction. From there you can join to v$session, which should give you an idea about the UI (try the program and machine columns) as well as the user.

Yes! You can definitely use onclick or you can also use addEventListener to listen a click event. In this code sample the onclick event is in action(use).

HTML code:

<div class="container">
<p><output id="output">0</output></p>
<p><button type="button" id="btn">Increment</button></p>
</div>

Javascript code:

(function() {
 var button = document.getElementById("btn")
 var output = document.getElementById("output")
 var number
 var counter
 

 function init() {
 // Convert string to primitve number using parseInt()
  number = parseInt(output.innerText)
  
 /**
 * Start counter by adding any number to start counting.
 * In this case the output starts from 0 so to immediately
 * invoke the button to increment the counter add 1 to start 
 * counting in natural number (counting numbers).
 */  counter = number + 1
  
  function increment() {
    // Increment counter
    value = counter++
    output.innerText = value
   }
  
   // Output the increment value for every click
    button.onclick = increment
 }

 window.onload = init
})()

Demo

Replace your recyclerView with,

<android.support.v7.widget.RecyclerView
    android:id="@+id/conversation"
    app:layout_behavior="@string/appbar_scrolling_view_behavior"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" />

here,

app:layout_behavior="@string/appbar_scrolling_view_behavior"

will manage the rest of things.

One more thing, no need to put your recyclerView inside NestedScrollView

The second for loop is any easy way to iterate over the contents of an array, without having to manually specify the number of items in the array(manual enumeration). It is much more convenient than the first when dealing with arrays.

Ok, so very important to realize the implications here.

Docs say that SSL over 465 is NOT supported in SmtpClient.

Seems like you have no choice but to use STARTTLS which may not be supported by your mail host. You may have to use a different library if your host requires use of SSL over 465.

Quoted from http://msdn.microsoft.com/en-us/library/system.net.mail.smtpclient.enablessl(v=vs.110).aspx

The SmtpClient class only supports the SMTP Service Extension for Secure SMTP over Transport Layer Security as defined in RFC 3207. In this mode, the SMTP session begins on an unencrypted channel, then a STARTTLS command is issued by the client to the server to switch to secure communication using SSL. See RFC 3207 published by the Internet Engineering Task Force (IETF) for more information.

An alternate connection method is where an SSL session is established up front before any protocol commands are sent. This connection method is sometimes called SMTP/SSL, SMTP over SSL, or SMTPS and by default uses port 465. This alternate connection method using SSL is not currently supported.
