To late for the original asker of the question, but with SQL Server 2008 R2 this is now possible:

Set the property "Pagebreak" on the tablix or table or other element to force a new tab, and then set the property "Pagename" on both the element before the pagebreak and the element after the pagebreak. These names will appear on the tabs when the report is exported to Excel.

Read about it here: http://technet.microsoft.com/en-us/library/dd255278.aspx

You can use this function I wrote. You call GetTimeMs64(), and it returns the number of milliseconds elapsed since the unix epoch using the system clock - the just like time(NULL), except in milliseconds.

It works on both windows and linux; it is thread safe.

Note that the granularity is 15 ms on windows; on linux it is implementation dependent, but it usually 15 ms as well.

#ifdef _WIN32
#include <Windows.h>
#else
#include <sys/time.h>
#include <ctime>
#endif

/* Remove if already defined */
typedef long long int64; typedef unsigned long long uint64;

/* Returns the amount of milliseconds elapsed since the UNIX epoch. Works on both
 * windows and linux. */

uint64 GetTimeMs64()
{
#ifdef _WIN32
 /* Windows */
 FILETIME ft;
 LARGE_INTEGER li;

 /* Get the amount of 100 nano seconds intervals elapsed since January 1, 1601 (UTC) and copy it
  * to a LARGE_INTEGER structure. */
 GetSystemTimeAsFileTime(&ft);
 li.LowPart = ft.dwLowDateTime;
 li.HighPart = ft.dwHighDateTime;

 uint64 ret = li.QuadPart;
 ret -= 116444736000000000LL; /* Convert from file time to UNIX epoch time. */
 ret /= 10000; /* From 100 nano seconds (10^-7) to 1 millisecond (10^-3) intervals */

 return ret;
#else
 /* Linux */
 struct timeval tv;

 gettimeofday(&tv, NULL);

 uint64 ret = tv.tv_usec;
 /* Convert from micro seconds (10^-6) to milliseconds (10^-3) */
 ret /= 1000;

 /* Adds the seconds (10^0) after converting them to milliseconds (10^-3) */
 ret += (tv.tv_sec * 1000);

 return ret;
#endif
}

Use this:

SELECT 
    Pieces, Price, 
    Pieces * Price as 'Total' 
FROM myTable

Try This:

//urlPath = address of your picture on internet
URL url = new URL("urlPath");
BufferedImage c = ImageIO.read(url);
ImageIcon image = new ImageIcon(c);
jXImageView1.setImage(image);

It's common for other components to be listening to the change event, or for custom event handlers to be attached that may have side effects. Select2 does not have a custom event (like select2:update) that can be triggered other than change. You can rely on jQuery's event namespacing to limit the scope to Select2 though by triggering the *change.select2 event.

$('#state').trigger('change.select2'); // Notify only Select2 of changes

Missing square brackets around input property may cause this error. For example:

Component Foo {
    @Input()
    bars: BarType[];
}

Correct:

<app-foo [bars]="smth"></app-foo>

Incorrect (triggering error):

<app-foo bars="smth"></app-foo>

Case 1 : Yes, this works fine.

Case 2 : This will fail with the error ORA-01441 : cannot decrease column length because some value is too big.

I'm not sure why this code works, but it completely erases the original line. I compiled it from the previous answers. The other answers would just return the line to the beginning, but if you had a shorter line afterwards, it would look messed up like hello turns into byelo.

import sys
#include ctypes if you're on Windows
import ctypes
kernel32 = ctypes.windll.kernel32
kernel32.SetConsoleMode(kernel32.GetStdHandle(-11), 7)

def clearline(msg):
    CURSOR_UP_ONE = '\033[K'
    ERASE_LINE = '\x1b[2K'
    sys.stdout.write(CURSOR_UP_ONE)
    sys.stdout.write(ERASE_LINE+'\r')
    print(msg, end='\r')

#example
ig_usernames = ['beyonce','selenagomez']
for name in ig_usernames:
    clearline("SCRAPING COMPLETE: "+ name)

Output - Each line will be rewritten without any old text showing:

SCRAPING COMPLETE: selenagomez

Next line (rewritten completely on same line):

SCRAPING COMPLETE: beyonce

In one statement: No.

In one transaction: Yes

   SELECT @DataID = scope_identity();
   INSERT INTO LinkTable VALUES (@ObjectID, @DataID);
COMMIT

The good news is that the above code is also guaranteed to be atomic, and can be sent to the server from a client application with one sql string in a single function call as if it were one statement. You could also apply a trigger to one table to get the effect of a single insert. However, it's ultimately still two statements and you probably don't want to run the trigger for every insert.

Yep, you are right, these are oop constructs.

__init__ is the constructor for a class. The self parameter refers to the instance of the object (like this in C++).

class Point:
    def __init__(self, x, y):
        self._x = x
        self._y = y

The __init__ method gets called when memory for the object is allocated:

x = Point(1,2)

It is important to use the self parameter inside an object's method if you want to persist the value with the object. If, for instance, you implement the __init__ method like this:

class Point:
    def __init__(self, x, y):
        _x = x
        _y = y

Your x and y parameters would be stored in variables on the stack and would be discarded when the init method goes out of scope. Setting those variables as self._x and self._y sets those variables as members of the Point object (accessible for the lifetime of the object).

//split string into an array and grab the first item

var streetaddress = addy.split(',')[0];

Also, I'd recommend naming your variables with camel-case(streetAddress) for better readability.

If the clients are using Android 6.0, Android added new permission model for (Marshmallow).

Trick: If you are targeting version 22 or below, your application will request all permissions at install time just as it would on any device running an OS below Marshmallow

You may can use -Xlinker option.

g++ -o foobar  -Xlinker -start-group  -Xlinker libA.a -Xlinker libB.a -Xlinker libC.a  -Xlinker -end-group 

is ALMOST equal to

g++ -o foobar  -Xlinker -start-group  -Xlinker libC.a -Xlinker libB.a -Xlinker libA.a  -Xlinker -end-group 

Careful !

1. The order within a group is important ! Here's an example: a debug library has a debug routine, but the non-debug library has a weak version of the same. You must put the debug library FIRST in the group or you will resolve to the non-debug version.
2. You need to precede each library in the group list with -Xlinker

Take a look at BackgroundWorker Class, with the OnRunWorkerCompleted you can do it.

I'm thinking no. Bookmarks/favorites should be under the control of the user, imagine if any site you visited could insert itself into your bookmarks with just some javascript.

Using the Random class is the way to go as suggested in the accepted answer, but here is a less straight-forward correct way of doing it if you didn't want to create a new Random object :

min + (int) (Math.random() * (max - min + 1));

All you need to do is to add app.UseStaticFiles(); in your startup.cs -> public void Configure(IApplicationBuilder app, IHostingEnvironment env).

ASP.net core provides an excellent way to get static files. That is using the wwwroot folder. Please read Static files in ASP.NET Core.

Using the <Link /> is not a very good idea. Why would someone add the link tag on each HTML or cshtml for the favicon.ico?

Solution is you need to add json file extension type in MIME Types

Method 1

Go to IIS, Select your application and Find MIME Types

Click on Add from Right panel

File Name Extension = .json

MIME Type = application/json

After adding .json file type in MIME Types, Restart IIS and try to access json file

Method 2

Go to web.config of that application and add this lines in it

 <system.webServer>
   <staticContent>
     <mimeMap fileExtension=".json" mimeType="application/json" />
   </staticContent>
 </system.webServer>

Open the Servers view -> double click tomcat -> drop down the Timeouts section

There you can increase the startup time for each particular server.

You must link an event in your onClick. Additionally, the click function must receive the event. See the example

export default function Component(props) {

    function clickEvent (event, variable){
        console.log(variable);
    }

    return (
        <div>
            <IconButton
                key="close"
                aria-label="Close"
                color="inherit"
                onClick={e => clickEvent(e, 10)}
            >
        </div>
    )
}

you can find the user in DBA_USERS table like

SELECT profile
FROM dba_users
WHERE username = 'MacsP'

Now go to the sys/system (administrator) and use query

ALTER USER PRATEEK
IDENTIFIED BY "new_password"
REPLACE "old_password"

To verify the account status just go through

SELECT * FROM DBA_USERS.

and you can see status of your user.

Instead of defining the width, you could just put a margin-left on your li, so that the spacing is consistent, and just make sure the margin(s)+li fit within 900px.

nav li {
  line-height: 87px;
  float: left;
  text-align: center;
  margin-left: 35px;
}

Hope this helps.

char* is a mutable pointer to a mutable character/string.

const char* is a mutable pointer to an immutable character/string. You cannot change the contents of the location(s) this pointer points to. Also, compilers are required to give error messages when you try to do so. For the same reason, conversion from const char * to char* is deprecated.

char* const is an immutable pointer (it cannot point to any other location) but the contents of location at which it points are mutable.

const char* const is an immutable pointer to an immutable character/string.

The inner vertical alignment will depend on font height and input height, so, it can be adjusted using padding !!!

Try some like :

.InVertAlign {
   height: 40px;
   line-height: 40px;
   font-size: 2em;
   padding: 0px 14px 3px 5px;
}

...

<input type="text" class="InVertAlign" />

Remember to adjust the values on css class according to your needs !

generating a fresh access key worked for me.

There are instances when element.isDisplayed() && element.isEnabled() will return true but still element will not be clickable, because it is hidden/overlapped by some other element.

In such case, Exception caught is:

org.openqa.selenium.WebDriverException: unknown error: Element is not clickable at point (781, 704). Other element would receive the click: <div class="footer">...</div>

Use this code instead:

WebElement  element=driver.findElement(By.xpath"");  
JavascriptExecutor ex=(JavascriptExecutor)driver;
ex.executeScript("arguments[0].click()", element);

It will work.

Nobody suggested this, but you can use -Dmaven.repo.local command line argument to change where the repository is at. In addition, according to settings.xml documentation, you can set -Dmaven.home where it looks for the settings.xml file.

For MongoDB shell version v4.2.8 I've tried different ways to back-up my database with auth, my winner solution is

mongodump -h <your_hostname> -d <your_db_name> -u <your_db_username> -p <your_db_password> --authenticationDatabase admin -o /path/to/where/i/want

Android provides a couple of different library sets. One is called the Android support Library, and the other is called AndroidX. Selecting "Use android.* artifacts" indicates that we want to use AndroidX.

simply put this at the end of your code:

while(1){ }

this function will keep going on forever(or until you close the console) and will keep the console it from closing on its own.

First of all you need to set the responseType to arraybuffer. This is required if you want to create a blob of your data. See Sending_and_Receiving_Binary_Data. So your code will look like this:

$http.post('/postUrlHere',{myParams}, {responseType:'arraybuffer'})
  .success(function (response) {
       var file = new Blob([response], {type: 'application/pdf'});
       var fileURL = URL.createObjectURL(file);
});

The next part is, you need to use the $sce service to make angular trust your url. This can be done in this way:

$scope.content = $sce.trustAsResourceUrl(fileURL);

Do not forget to inject the $sce service.

If this is all done you can now embed your pdf:

<embed ng-src="{{content}}" style="width:200px;height:200px;"></embed>

.values()

You can call the values() method on your enum.

for (Direction dir : Direction.values()) {
  // do what you want
}

This values() method is implicitly declared by the compiler. So it is not listed on Enum doc.

The value of event handler attributes such as onclick should just be JavaScript, without any "javascript:" prefix. The javascript: pseudo-protocol is used in a URL, for example:

<a href="javascript:func(this)">here</a>

You should use the onclick="func(this)" form in preference to this though. Also note that in my example above using the javascript: pseudo-protocol "this" will refer to the window object rather than the <a> element.

Mine was quite a unique case but this could help someone. On Android I tried to copy nano from my termux binary folder to /system/xbin. Placed all the library dependencies in /system/lib and got this error. The libncurses.so.6 file I copied from termux had it's TERMINFO file still pointed to /data/data/com.termux/files/usr/share/terminfo

View pointed path with command

strings path-to-libncurses.so | grep /terminfo

To fix either make the termux terminfo dir and subdirs readable and executable by the nano user or copy the terminfo folder somewhere else and use a hexeditor to modify the plain text path in the shared library file.

Duh.... listFiles requires java.io.FileFilter. FileNameExtensionFilter extends javax.swing.filechooser.FileFilter. I solved my problem by implementing an instance of java.io.FileFilter

Edit: I did use something similar to @cFreiner's answer. I was trying to use a Java API method instead of writing my own implementation which is why I was trying to use FileNameExtensionFilter. I have many FileChoosers in my application and have used FileNameExtensionFilters for that and I mistakenly assumed that it was also extending java.io.FileFilter.

The easiest way to concat a static text string to a selected value is to use element.

<a>
  <xsl:attribute name="href"> 
    <xsl:value-of select="/*/properties/property[@name='report']/@value" />
    <xsl:text>staticIconExample.png</xsl:text>
  </xsl:attribute>
</a>

As many of the answer suggesting better solution is to use ArrayList. ArrayList size is not fixed and it is easily manageable.

It is resizable-array implementation of the List interface. Implements all optional list operations, and permits all elements, including null. In addition to implementing the List interface, this class provides methods to manipulate the size of the array that is used internally to store the list.

Each ArrayList instance has a capacity. The capacity is the size of the array used to store the elements in the list. It is always at least as large as the list size. As elements are added to an ArrayList, its capacity grows automatically.

Note that this implementation is not synchronized.

ArrayList<String> scripts = new ArrayList<String>();
scripts.add("test1");
scripts.add("test2");
scripts.add("test3");

As gratitude to the timely help I got from here - a minor update to above.

$query = "UPDATE `db`.`table` SET `fieldname`=  str_to_date(  fieldname, '%d/%m/%Y')";

In your css add folllowing

[ng\:cloak], [ng-cloak], [data-ng-cloak], [x-ng-cloak], .ng-cloak, .x-ng-cloak {
    display: none !important;
 }

And then in you code you can add ng-cloak directive. For example,

<div ng-cloak>
   Welcome {{data.name}}
</div>

Thats it!

I simply ran the command below:

export LD_LIBRARY_PATH=/usr/lib/

Now it is working fine.

Cookies and session both store information about the user (to make the HTTP request stateful) but the difference is that cookies store information on the client-side (browser) and sessions store information on the server-side. A cookie is limited in the sense that it stores information about limited users and only stores limited content for each user. A session is not limit in such a way.

Want to add an answer here for the sake of completeness.

<a href="tel:1234567">Call 123-4567</a>

Works just fine on most devices. However, on desktops this will appear as a link which does nothing when you click on it so you should consider using CSS to make it conditionally visible only on mobile devices.

Also, you should know that Skype (which is fairly popular) uses a different syntax by default (but can be parametered to use tel:).

<a href="callto:1234567">Call 123-4567</a>

However, I think in latest mobile browsers (I know for sure on Android) now the tel syntax should offer a popup of available applications that can be used to complete the calling action.

1. To Compile your C++ code use:-

g++ file_name.cpp -o executable_file_name

(i) -o option is used to show error in the code (ii) if there is no error in the code_file, then it will generate an executable file.

2. Now execute the generated executable file:

./executable_file_name

I faced the same problem. I restarted the oracle service for that DB instance and the error is gone.

try this out

public class RandomValueGenerator {
    /**
     * 
     */
    private volatile List<Double> previousGenValues = new ArrayList<Double>();

    public void init() {
        previousGenValues.add(Double.valueOf(0));
    }

    public String getNextValue() {
        Random random = new Random();
        double nextValue=0;
        while(previousGenValues.contains(Double.valueOf(nextValue))) {
            nextValue = random.nextDouble();
        }
        previousGenValues.add(Double.valueOf(nextValue));
        return String.valueOf(nextValue);
    }
}

On Ubuntu 14.04 I installed it from apt-get and it worked fine:

sudo apt-get install python-beautifulsoup

Then just do:

from BeautifulSoup import BeautifulSoup

If you'd like to capture all monitors, you can use the following code:

GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
GraphicsDevice[] screens = ge.getScreenDevices();

Rectangle allScreenBounds = new Rectangle();
for (GraphicsDevice screen : screens) {
    Rectangle screenBounds = screen.getDefaultConfiguration().getBounds();

    allScreenBounds.width += screenBounds.width;
    allScreenBounds.height = Math.max(allScreenBounds.height, screenBounds.height);
}

Robot robot = new Robot();
BufferedImage screenShot = robot.createScreenCapture(allScreenBounds);

All standard implementations of java.util.List already implement java.io.Serializable.

So even though java.util.List itself is not a subtype of java.io.Serializable, it should be safe to cast the list to Serializable, as long as you know it's one of the standard implementations like ArrayList or LinkedList.

If you're not sure, then copy the list first (using something like new ArrayList(myList)), then you know it's serializable.

Your command is completely incorrect. The output format is not rawvideo and you don't need the bitstream filter h264_mp4toannexb which is used when you want to convert the h264 contained in an mp4 to the Annex B format used by MPEG-TS for example. What you want to use instead is the aac_adtstoasc for the AAC streams.

ffmpeg -i http://.../playlist.m3u8 -c copy -bsf:a aac_adtstoasc output.mp4

When the JVM tries to run your application, it calls your main method statically; something like this:

LinkedList.main();

That means there is no instance of your LinkedList class. In order to call your toString() method, you can create a new instance of your LinkedList class.

So the body of your main method should be like this:

public static void main(String[] args){
    // creating an instance of LinkedList class
    LinkedList ll = new LinkedList();

    // adding some data to the list
    ll.insertFront(1);
    ll.insertFront(2);
    ll.insertFront(3);
    ll.insertBack(4);

    System.out.println(ll.toString());
}

If you want to trim and print one dimensional Array or the deepest dimension of multi-dimensional Array you should use:

foreach($array as $key => $value)
{
    $array[$key] = trim($value);
    print("-");
    print($array[$key]);
    print("-");
    print("<br>");
}

If you want to trim but do not want to print one dimensional Array or the deepest dimension of multi-dimensional Array you should use:

$array = array_map('trim', $array);

Do you mean any specific syntax for wildcards? Usually * stands for "one or many" characters and ? stands for one.

The simplest way probably is to translate a wildcard expression into a regular expression, then use that for filtering the results.

Just remind that if you just change it, it may take up to 5 minutes for settings to take effect.

I found App called Iconizer. You can find repository on github. Iconizer can generate app icons for OS X, iPad, iPhone, CarPlay and Apple Watch with just one image.

Simply Drag and Drop your icon onto Iconizer, select the platforms you need and whether or not you want all platforms generated into one asset catalog, then hit export.

After that just replace (delete and import) your AppIcon in the Assets.xcassets

While applying the new profile to the user,you should also check for resource limits are "turned on" for the database as a whole i.e.RESOURCE_LIMIT = TRUE

Let check the parameter value.
If in Case it is :

SQL> show parameter resource_limit

------------------------------------ ----------- ---------
resource_limit                       boolean     FALSE
Its mean resource limit is off,we ist have to enable it. 

Use the ALTER SYSTEM statement to turn on resource limits. 

SQL> ALTER SYSTEM SET RESOURCE_LIMIT = TRUE;
System altered.

The Mozilla.org FAQ on debugging Mozilla on Windows is of interest here.

In short, the Visual Studio debugger can be invoked on a program from the command line, allowing one to specify the command line arguments when invoking a command line program, directly on the command line.

This looks like the following for Visual Studio 8 or 9 (Visual Studio 2005 or Visual Studio 2008, respectively)

  devenv /debugexe 'program name' 'program arguments'

It is also possible to have an explorer action to start a program in the Visual Studio debugger.

Once you 'checkout' the development branch you ...

 git add .
 git commit -m "first commit"
 git push origin dev
 git merge master

It's been a while and I don't remember which book taught me this algorithm, but I thought it was quite ingenious and simple to understand:

char input[] = "moc.wolfrevokcats";

int length = strlen(input);
int last_pos = length-1;
for(int i = 0; i < length/2; i++)
{
    char tmp = input[i];
    input[i] = input[last_pos - i];
    input[last_pos - i] = tmp;
}

printf("%s\n", input);

A visualization of this algorithm, courtesy of slashdottir:

It's all about the linkage.

The previous answers provided good explainations about extern.

But I want to add an important point.

You ask about extern in C++ not in C and I don't know why there is no answer mentioning about the case when extern comes with const in C++.

In C++, a const variable has internal linkage by default (not like C).

So this scenario will lead to linking error:

Source 1 :

const int global = 255; //wrong way to make a definition of global const variable in C++

Source 2 :

extern const int global; //declaration

It need to be like this:

Source 1 :

extern const int global = 255; //a definition of global const variable in C++

Source 2 :

extern const int global; //declaration

You need to cast the array - the returned array is actually of the requested type, i.e. myEnum[] if you ask for typeof(myEnum):

myEnum[] values = (myEnum[]) Enum.GetValues(typeof(myEnum));

Then values[0] etc

Swift 5+

extension Date {
    
    func get(_ type: Calendar.Component)-> String {
        let calendar = Calendar.current
        let t = calendar.component(type, from: self)
        return (t < 10 ? "0\(t)" : t.description)
    }
}

Usage:

print(Date().get(.year)) // => 2020
print(Date().get(.month)) // => 08
print(Date().get(.day)) // => 18 

Sometimes if you use JavaScript the DocumentComplete event don't return the right answer; I use the event ProgressChanged instead:

Private Sub WebBrowser1_ProgressChanged(sender As Object, e As WebBrowserProgressChangedEventArgs) Handles WebBrowser1.ProgressChanged

        Console.WriteLine("Current Progress: " + e.CurrentProgress.ToString)

        If e.CurrentProgress = e.MaximumProgress Then

            ' The maximum progress is reached
            load_started = True

        End If

        ' The page is confirmed downloaded after the progress returns to 0
        If e.CurrentProgress = 0 Then

            If load_started Then

                ' The page is ready to print or download...
                WebBrowser1.Print()
                load_started = False

            End If

        End If

End Sub

In HTML5 you can use the new 'email' type: http://www.w3.org/TR/html-markup/input.email.html

For example:

<input type="email" id="email" />

If the browser implements HTML5 it will make sure that the user has entered a valid email address in the field. Note that if the browser doesn't implement HTML5, it will be treated like a 'text' type, ie:

<input type="text" id="email" />

Move

Random pp = new Random();
int a1 = pp.nextInt(10);
TextView tv = (TextView)findViewById(R.id.tv);
tv.setText(a1);

To inside onCreate(), and change tv.setText(a1); to tv.setText(String.valueOf(a1)); :

@Override
protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);

  Random pp = new Random();
  int a1 = pp.nextInt(10);

  TextView tv = (TextView)findViewById(R.id.tv);
  tv.setText(String.valueOf(a1));

}   

First issue: findViewById() was called before onCreate(), which would throw an NPE.

Second issue: Passing an int directly to a TextView calls the overloaded method that looks for a String resource (from R.string). Therefore, we want to use String.valueOf() to force the String overloaded method.

The Main method is static inside the Program class. You can't call an instance method from inside a static method, which is why you're getting the error.

To fix it you just need to make your GetRandomBits() method static as well.

From the doc for path.resolve:

The resulting path is normalized and trailing slashes are removed unless the path is resolved to the root directory.

But path.join keeps trailing slashes

So

__dirname = '/';
path.resolve(__dirname, 'foo/'); // '/foo'
path.join(__dirname, 'foo/'); // '/foo/'

You do not need to use the while True: loop in this case. There is a much simpler way to use the time condition directly:

import time

# timeout variable can be omitted, if you use specific value in the while condition
timeout = 300   # [seconds]

timeout_start = time.time()

while time.time() < timeout_start + timeout:
    test = 0
    if test == 5:
        break
    test -= 1

For the rows containing strings, I can convert them to strings as in changing

tmpStr = nameItem("lastname") + " " + nameItem("initials")

to

tmpStr = myItem("lastname").toString + " " + myItem("intials").toString

For the comparison in the if statement myItem("sID")=sID, it needs to be change to

myItem("sID").Equals(sID)

Then the code will run without any runtime errors due to vbNull data.

in my case it is present as "php.ini-development" and "php.ini-production" in php folder

Unfortunately none of the solutions works for me.

1. If you don't set pressed state at first it won't detect it.
2. If you set it, then you need to define empty state to add default color

ColorStateList themeColorStateList = new ColorStateList(
        new int[][]{
                new int[]{android.R.attr.state_pressed},
                new int[]{android.R.attr.state_enabled},
                new int[]{android.R.attr.state_focused, android.R.attr.state_pressed},
                new int[]{-android.R.attr.state_enabled},
                new int[]{} // this should be empty to make default color as we want
        },
        new int[]{
                pressedFontColor,
                defaultFontColor,
                pressedFontColor,
                disabledFontColor,
                defaultFontColor
        }
);

This is constructor from source code:

/**
 * Creates a ColorStateList that returns the specified mapping from
 * states to colors.
 */
public ColorStateList(int[][] states, int[] colors) {
    mStateSpecs = states;
    mColors = colors;

    if (states.length > 0) {
        mDefaultColor = colors[0];

        for (int i = 0; i < states.length; i++) {
            if (states[i].length == 0) {
                mDefaultColor = colors[i];
            }
        }
    }
}

RC's post was SUPER useful. I never thought about using the $(dir $@) function, but it did exactly what I needed it to do.

In parentDir, have a bunch of directories with source files in them: dirA, dirB, dirC. Various files depend on the object files in other directories, so I wanted to be able to make one file from within one directory, and have it make that dependency by calling the makefile associated with that dependency.

Essentially, I made one Makefile in parentDir that had (among many other things) a generic rule similar to RC's:

%.o : %.cpp
        @mkdir -p $(dir $@)
        @echo "============="
        @echo "Compiling $<"
        @$(CC) $(CFLAGS) -c $< -o $@

Each subdirectory included this upper-level makefile in order to inherit this generic rule. In each subdirectory's Makefile, I wrote a custom rule for each file so that I could keep track of everything that each individual file depended on.

Whenever I needed to make a file, I used (essentially) this rule to recursively make any/all dependencies. Perfect!

NOTE: there's a utility called "makepp" that seems to do this very task even more intuitively, but for the sake of portability and not depending on another tool, I chose to do it this way.

Hope this helps!

typeof is an operator to obtain a type known at compile-time (or at least a generic type parameter). The operand of typeof is always the name of a type or type parameter - never an expression with a value (e.g. a variable). See the C# language specification for more details.

GetType() is a method you call on individual objects, to get the execution-time type of the object.

Note that unless you only want exactly instances of TextBox (rather than instances of subclasses) you'd usually use:

if (myControl is TextBox)
{
    // Whatever
}

Or

TextBox tb = myControl as TextBox;
if (tb != null)
{
    // Use tb
}

Fast and simple solution.

I was using Maven in eclipse and I did not want to have an additional copy of the properties file in the root folder. You can do the following in eclipse:

1. Open run dialog (click the little arrow next to the play button and go to run configurations)
2. Go to the "classpath" tab
3. Select the "User Entries" and click the "Advanced" button on the right side.
4. Now select the "Add External folder" radio button.
5. Select the resources folder

In addition to Jim's answer (sorry not enough rep points to make a comment), just wanted to point out that the arguments specified in PyCharm do not have special characters escaped, unlike what you would do on the command line. So, whereas on the command line you'd do:

python mediadb.py  /media/paul/New\ Volume/Users/paul/Documents/spinmaster/\*.png

the PyCharm parameter would be:

"/media/paul/New Volume/Users/paul/Documents/spinmaster/*.png"

For Linux let me introduce a shell script that will show the mac address and allows to change it (MAC sniffing).

 ifconfig eth0 | grep HWaddr |cut -dH -f2|cut -d\  -f2
 00:26:6c:df:c3:95

Cut arguements may dffer (I am not an expert) try:

ifconfig etho | grep HWaddr
eth0      Link encap:Ethernet  HWaddr 00:26:6c:df:c3:95  

To change MAC we may do:

ifconfig eth0 down
ifconfig eth0 hw ether 00:80:48:BA:d1:30
ifconfig eth0 up

will change mac address to 00:80:48:BA:d1:30 (temporarily, will restore to actual one upon reboot).

There are already answers which describes about window.location.href property and window.open() method.

I will go by Objective use:

1. To redirect the page to another

Use window.location.href. Set href property to the href of another page.

2. Open link in the new or specific window.

Use window.open(). Pass parameters as per your goal.

3. Know current address of the page

Use window.location.href. Get value of window.location.href property. You can also get specific protocol, hostname, hashstring from window.location object.

See Location Object for more information.

Another method for those who really want to do this in spite of the correct remarks that you shouldn't:

import unittest

class MyTest(unittest.TestCase):

    def __init__(self, testName, extraArg):
        super(MyTest, self).__init__(testName)  # calling the super class init varies for different python versions.  This works for 2.7
        self.myExtraArg = extraArg

    def test_something(self):
        print(self.myExtraArg)

# call your test
suite = unittest.TestSuite()
suite.addTest(MyTest('test_something', extraArg))
unittest.TextTestRunner(verbosity=2).run(suite)

In Ionic I was able to find it here: /app/platforms/android/app/build/intermediates/signing_config/release/out/signing-config.json

Maybe this will help someone. cheers.

Don't know if of help, but in my case I had my resource in the /src/ folder and was getting this error. I then moved the picture to the bin folder and it fixed the issue.

Here's how to do it with an HTML Blob, so that you have control over the entire HTML document:

https://codepen.io/trusktr/pen/mdeQbKG?editors=0010

This is the code, but StackOverflow blocks the window from being opened (see the codepen example instead):

const winHtml = `<!DOCTYPE html>_x000D_
    <html>_x000D_
        <head>_x000D_
            <title>Window with Blob</title>_x000D_
        </head>_x000D_
        <body>_x000D_
            <h1>Hello from the new window!</h1>_x000D_
        </body>_x000D_
    </html>`;_x000D_
_x000D_
const winUrl = URL.createObjectURL(_x000D_
    new Blob([winHtml], { type: "text/html" })_x000D_
);_x000D_
_x000D_
const win = window.open(_x000D_
    winUrl,_x000D_
    "win",_x000D_
    `width=800,height=400,screenX=200,screenY=200`_x000D_
);

Open another url like a click in link

window.location.href = "http://example.com";

When your form is maximized, set its minimum size = max size, so user cannot resize it.

    this.WindowState = FormWindowState.Maximized;
    this.MinimumSize = this.Size;
    this.MaximumSize = this.Size;

Type py -v instead of python -v in command prompt

RUN /bin/bash -c "source /usr/local/bin/virtualenvwrapper.sh"

Replace it with a reusable NOOP (no operation) function.

// this function does nothing
function noop() {};

function foo() {
    foo = noop; // swap the functions

    // do your thing
}

function bar() {
    bar = noop; // swap the functions

    // do your thing
}

None of the mentioned answers worked for me. However, what worked for me is port forwarding. Steps detailed here:

1. Ensure you have adb installed (steps here for windowd, mac, ubuntu)
2. Ensure you have chrome running on your mobile device

3. On your PC, run the following from command line:

   adb forward tcp:9222 localabstract:chrome_devtools_remote

4. On running the above command, accept the authorization on your mobile phone. Below is the kind of output I see on my laptop:

   $:/> adb forward tcp:9222 localabstract:chrome_devtools_remote

   * daemon not running. starting it now on port 5037 *

   * daemon started successfully *

5. Now open your chrome and enter 'localhost:9222' and you shall see the active tab to inspect.

Here is the source for this approach

Try

NSDate *future = [NSDate dateWithTimeIntervalSinceNow: 0.06 ];
[NSThread sleepUntilDate:future];

Here is my version. I may change it after I look at these examples.

$.fn.pixels = function(property){
    return parseInt(this.css(property));
};

$.fn.center = function(){
    var w = $($w);
    return this.each(function(){
        $(this).css("position","absolute");
        $(this).css("top",((w.height() - $(this).height()) / 2) - (($(this).pixels('padding-top') + $(this).pixels('padding-bottom')) / 2) + w.scrollTop() + "px");
        $(this).css("left",((w.width() - $(this).width()) / 2) - (($(this).pixels('padding-left') + $(this).pixels('padding-right')) / 2) + w.scrollLeft() + "px");
    });
};

Arrays.stream(ints).forEach(list::add);

Be careful, - has a special meaning with regexp. In a [], you can put it without problem if it is placed at the end. In your case, ,-: is taken as from , to :.

Here's a quick solution for most of the cases:

CSS:

.iframe-loading { 
    background:url(/img/loading.gif) center center no-repeat; 
}

You can use an animated loading GIF if you want to,

HTML:

<div class="iframe-loading">
    <iframe src="http://your_iframe_url_goes_here"  onload="$('.iframe-loading').css('background-image', 'none');"></iframe>
</div>

Using the onload event you can remove the loading image after the source page is loaded inside your iframe.

If you are not using jQuery, just put an id into the div and replace this part of code:

$('.iframe-loading').css('background-image', 'none');

by something like this:

document.getElementById("myDivName").style.backgroundImage = "none";

All the best!

Take a look at this JQuery plugin:

http://fixedheadertable.com

It adds vertical (fixed header row) or horizontal (fixed first column) scrolling to an existing HTML table. There is a demo you can check for both cases of scrolling.

What basically happens is,According to default updatePolicy of maven.Maven will fetch the jars from repo on daily basis.So if during 1st attempt your internet was not working then it would not try to fetch this jar again untill 24hours spent.

Resolution :

Either use

mvn -U clean install

where -U will force update the repo

or use

<profiles>
    <profile>
      ...
      <repositories>
        <repository>
          <id>myRepo</id>
          <name>My Repository</name>
          <releases>
            <enabled>false</enabled>
            <updatePolicy>always</updatePolicy>
            <checksumPolicy>warn</checksumPolicy>
          </releases>
         </repository>
      </repositories>
      ...
    </profile>
  </profiles>

in your settings.xml

Use Node.js's built-in copy function

It provides both async and sync version:

const fs = require('fs');

// File "destination.txt" will be created or overwritten by default.
fs.copyFile('source.txt', 'destination.txt', (err) => {
  if (err) 
      throw err;
  console.log('source.txt was copied to destination.txt');
});

fs.copyFileSync(src, dest[, mode])

JSON is perfectly capable of expressing lists of integers, and the JSON you have posted is valid. You can simply separate the integers by commas:

{
    "Id": "610",
    "Name": "15",
    "Description": "1.99",
    "ItemModList": [42, 47, 139]
}

With Firefox, I:

1. Downloaded and unpacked a version of Swagger.IO to C:\Swagger\
2. Created a folder called Definitions in C:\Swagger\dist
3. Copied my swagger.json definition file there, and
4. Entered "Definitions/MyDef.swagger.json" in the Explore box

Be careful of your slash directions!!

It seems you can drill down in folder structure but not up, annoyingly.

You are trying to execute the number in the ENDTIME as a command. You should also see an error like 1370306857: command not found. Instead use the arithmetic expansion:

echo "It takes $(($ENDTIME - $STARTTIME)) seconds to complete this task..."

You could also save the commands in a separate script, commands.sh, and use time command:

time commands.sh

You can use Jquery's on method and listen for the scroll event.

Partial Key:

It is a set of attributes that can uniquely identify weak entities and that are related to same owner entity. It is sometime called as Discriminator.

Alternate Key:

All Candidate Keys excluding the Primary Key are known as Alternate Keys.

Artificial Key:

If no obvious key, either stand alone or compound is available, then the last resort is to simply create a key, by assigning a unique number to each record or occurrence. Then this is known as developing an artificial key.

Compound Key:

If no single data element uniquely identifies occurrences within a construct, then combining multiple elements to create a unique identifier for the construct is known as creating a compound key.

Natural Key:

When one of the data elements stored within a construct is utilized as the primary key, then it is called the natural key.

They both work the same. However, note that if both are defined, only one of them will be invoked. I generally avoid using either of them directly. Instead, you can attach an event handler to the load event. This way you can incorporate more easily other JS packages which might also need to attach a callback to the onload event.

Any JS framework will have cross-browser methods for event handlers.

This is the complete way to omit unneeded redirects, too ;)

These rules are intended to be used in .htaccess files, as a RewriteRule in a *:80 VirtualHost entry needs no Conditions.

RewriteEngine on
RewriteCond %{HTTPS} off [OR] 
RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteRule ^/(.*) https://%{HTTP_HOST}/$1 [NC,R=301,L]

Eplanations:

RewriteEngine on

==> enable the engine at all

RewriteCond %{HTTPS} off [OR]

==> match on non-https connections, or (not setting [OR] would cause an implicit AND !)

RewriteCond %{HTTP:X-Forwarded-Proto} !https

==> match on forwarded connections (proxy, loadbalancer, etc.) without https

RewriteRule ^/(.*) https://%{HTTP_HOST}/$1 [NC,R=301,L]

==> if one of both Conditions match, do the rewrite of the whole URL, sending a 301 to have this 'learned' by the client (some do, some don't) and the L for the last rule.

The object (i.e. destination variable) for the AddDays method can't be the same as the source.

Instead of:

DateTime today = DateTime.Today;
today.AddDays(-7);

Try this instead:

DateTime today = DateTime.Today;
DateTime sevenDaysEarlier = today.AddDays(-7);

If you're writing GPLed code and using GNU autotools, then a portable way that takes care of the details on many OSes (including Windows and macOS) is gnulib's relocatable-prog module.

UPDATE since version 5.4 of Laravel it is no longer possible.

You can change your db config, like @Varun suggested, or if you want to do it just in this very case, then:

DB::setFetchMode(PDO::FETCH_ASSOC);

// then
DB::table(..)->get(); // array of arrays instead of objects

// of course to revert the fetch mode you need to set it again
DB::setFetchMode(PDO::FETCH_CLASS);

For New Laravel above 5.4 (Ver > 5.4) see https://laravel.com/docs/5.4/upgrade fetch mode section

Event::listen(StatementPrepared::class, function ($event) {
    $event->statement->setFetchMode(...);
});

The -o option didn't work for me because the artifact is still in development and not yet uploaded and maven (3.5.x) still tries to download it from the remote repository because it's the first time, according to the error I get.

However this fixed it for me: https://maven.apache.org/general.html#importing-jars

After this manual install there's no need to use the offline option either.

UPDATE

I've just rebuilt the dependency and I had to re-import it: the regular mvn clean install was not sufficient for me

Don't make data frames. Keep the list, name its elements but do not attach it.

The biggest reason for this is that if you make variables on the go, almost always you will later on have to iterate through each one of them to perform something useful. There you will again be forced to iterate through each one of the names that you have created on the fly.

It is far easier to name the elements of the list and iterate through the names.

As far as attach is concerned, its really bad programming practice in R and can lead to a lot of trouble if you are not careful.

Here's a simple yield based approach, to compute the fibonacci series, explained:

def fib(limit=50):
    a, b = 0, 1
    for i in range(limit):
       yield b
       a, b = b, a+b

When you enter this into your REPL and then try and call it, you'll get a mystifying result:

>>> fib()
<generator object fib at 0x7fa38394e3b8>

This is because the presence of yield signaled to Python that you want to create a generator, that is, an object that generates values on demand.

So, how do you generate these values? This can either be done directly by using the built-in function next, or, indirectly by feeding it to a construct that consumes values.

Using the built-in next() function, you directly invoke .next/__next__, forcing the generator to produce a value:

>>> g = fib()
>>> next(g)
1
>>> next(g)
1
>>> next(g)
2
>>> next(g)
3
>>> next(g)
5

Indirectly, if you provide fib to a for loop, a list initializer, a tuple initializer, or anything else that expects an object that generates/produces values, you'll "consume" the generator until no more values can be produced by it (and it returns):

results = []
for i in fib(30):       # consumes fib
    results.append(i) 
# can also be accomplished with
results = list(fib(30)) # consumes fib

Similarly, with a tuple initializer:

>>> tuple(fib(5))       # consumes fib
(1, 1, 2, 3, 5)

A generator differs from a function in the sense that it is lazy. It accomplishes this by maintaining it's local state and allowing you to resume whenever you need to.

When you first invoke fib by calling it:

f = fib()

Python compiles the function, encounters the yield keyword and simply returns a generator object back at you. Not very helpful it seems.

When you then request it generates the first value, directly or indirectly, it executes all statements that it finds, until it encounters a yield, it then yields back the value you supplied to yield and pauses. For an example that better demonstrates this, let's use some print calls (replace with print "text" if on Python 2):

def yielder(value):
    """ This is an infinite generator. Only use next on it """ 
    while 1:
        print("I'm going to generate the value for you")
        print("Then I'll pause for a while")
        yield value
        print("Let's go through it again.")

Now, enter in the REPL:

>>> gen = yielder("Hello, yield!")

you have a generator object now waiting for a command for it to generate a value. Use next and see what get's printed:

>>> next(gen) # runs until it finds a yield
I'm going to generate the value for you
Then I'll pause for a while
'Hello, yield!'

The unquoted results are what's printed. The quoted result is what is returned from yield. Call next again now:

>>> next(gen) # continues from yield and runs again
Let's go through it again.
I'm going to generate the value for you
Then I'll pause for a while
'Hello, yield!'

The generator remembers it was paused at yield value and resumes from there. The next message is printed and the search for the yield statement to pause at it performed again (due to the while loop).

foreach my $arg (@ARGV) {
    print $arg, "\n";
}

will print each argument.

If you just need to try something out quickly, here's a quick and dirty solution. Use single quotes for the attribute value:

<parameter name='Quote = " '>

For future developers that are using AndroidX and the navigation architectural component.

Instead of setting the toolbar title using one of the solutions above, which can be very painful if you want to set it dynamically on a back stack change, you can set a placeholder for the title of the fragment in the navigation graph like the following:

<fragment
    android:id="@+id/some_fragment"
    android:name="package.SomeFragment"
    android:label="Hello {placeholder}"
    tools:layout="@layout/fragment_some">
    <argument
        android:name="placeholder"
        app:argType="string" />
</fragment>

The placeholder value has to be provided using the FragmentDirections (via the action method).

It is then replaced in the title and show like Hello World (when placeholder = "World").

Yes it is correct. you can do it with an inner class.

If you're trying this with GitHub, you can do this with your SSH entered:

git clone https://[email protected]/username/repository

self.materials is a dict and by default you are iterating over just the keys (which are strings).

Since self.materials has more than two keys*, they can't be unpacked into the tuple "k, m", hence the ValueError exception is raised.

In Python 2.x, to iterate over the keys and the values (the tuple "k, m"), we use self.materials.iteritems().

However, since you're throwing the key away anyway, you may as well simply iterate over the dictionary's values:

for m in self.materials.itervalues():

In Python 3.x, prefer dict.values() (which returns a dictionary view object):

for m in self.materials.values():

I got the same problem and this is how i solved. :

1. Right click your Spring MVC project, choose Run As -> Maven install. Observe the output console to see the installation progress. After the installation is finished, you can continue to the next step.

2. Right click your Spring MVC project, choose Maven -> Update Project.

3. Choose your project and click OK. Wait until update process is finished.
4. The error still yet, then do Project->Clean and then be sure you have selected our project directory and then do the follow Project->Build.

@@ denotes a class variable, i.e. it can be inherited.

This means that if you create a subclass of that class, it will inherit the variable. So if you have a class Vehicle with the class variable @@number_of_wheels then if you create a class Car < Vehicle then it too will have the class variable @@number_of_wheels

If you get a python error like this:

AttributeError: 'str' object has no attribute 'some_method'

You probably poisoned your object accidentally by overwriting your object with a string.

How to reproduce this error in python with a few lines of code:

#!/usr/bin/env python
import json
def foobar(json):
    msg = json.loads(json)

foobar('{"batman": "yes"}')

Run it, which prints:

AttributeError: 'str' object has no attribute 'loads'

But change the name of the variablename, and it works fine:

#!/usr/bin/env python
import json
def foobar(jsonstring):
    msg = json.loads(jsonstring)

foobar('{"batman": "yes"}')

This error is caused when you tried to run a method within a string. String has a few methods, but not the one you are invoking. So stop trying to invoke a method which String does not define and start looking for where you poisoned your object.

Alternative solution:

>>> from datetime import date
>>> (date(2012, 3, 1) - date(2012, 2, 1)).days

Use this:

return RedirectToAction("LogIn", "Account", new { area = "" });

This will redirect to the LogIn action in the Account controller in the "global" area.

It's using this RedirectToAction overload:

protected internal RedirectToRouteResult RedirectToAction(
    string actionName,
    string controllerName,
    Object routeValues
)

Currently there are three ways to write a file:

1. fs.write(fd, buffer, offset, length, position, callback)

   You need to wait for the callback to ensure that the buffer is written to disk. It's not buffered.

2. fs.writeFile(filename, data, [encoding], callback)

   All data must be stored at the same time; you cannot perform sequential writes.

3. fs.createWriteStream(path, [options])

   Creates a WriteStream, which is convenient because you don't need to wait for a callback. But again, it's not buffered.

A WriteStream, as the name says, is a stream. A stream by definition is “a buffer” containing data which moves in one direction (source ? destination). But a writable stream is not necessarily “buffered”. A stream is “buffered” when you write n times, and at time n+1, the stream sends the buffer to the kernel (because it's full and needs to be flushed).

In other words: “A buffer” is the object. Whether or not it “is buffered” is a property of that object.

If you look at the code, the WriteStream inherits from a writable Stream object. If you pay attention, you’ll see how they flush the content; they don't have any buffering system.

If you write a string, it’s converted to a buffer, and then sent to the native layer and written to disk. When writing strings, they're not filling up any buffer. So, if you do:

write("a")
write("b")
write("c")

You're doing:

fs.write(new Buffer("a"))
fs.write(new Buffer("b"))
fs.write(new Buffer("c"))

That’s three calls to the I/O layer. Although you're using “buffers”, the data is not buffered. A buffered stream would do: fs.write(new Buffer ("abc")), one call to the I/O layer.

As of now, in Node.js v0.12 (stable version announced 02/06/2015) now supports two functions: cork() and uncork(). It seems that these functions will finally allow you to buffer/flush the write calls.

For example, in Java there are some classes that provide buffered streams (BufferedOutputStream, BufferedWriter...). If you write three bytes, these bytes will be stored in the buffer (memory) instead of doing an I/O call just for three bytes. When the buffer is full the content is flushed and saved to disk. This improves performance.

I'm not discovering anything, just remembering how a disk access should be done.

You're not getting an "invalid date" error. Rather, the value of temp is "Invalid Date".

Is your date string in a valid format? If you're using Firefox, check Date.parse

In Firefox javascript console:

>>> Date.parse("2010-08-17 12:09:36");
NaN
>>> Date.parse("Aug 9, 1995")
807944400000

I would try a different date string format.

Zebi, are you using Internet Explorer?

Note - if you want to pass a data attribute to a React Component, you need to handle them a little differently than other props.

2 options

Don't use camel case

<Option data-img-src='value' ... />

And then in the component, because of the dashes, you need to refer to the prop in quotes.

// @flow
class Option extends React.Component {

  props: {
    'data-img-src': string
  }

And when you refer to it later, you don't use the dot syntax

  render () {
    return (
      <option data-img-src={this.props['data-img-src']} >...</option>
    )
  }
}

Or use camel case

<Option dataImgSrc='value' ... />

And then in the component, you need to convert.

// @flow
class Option extends React.Component {

  props: {
    dataImgSrc: string
  }

And when you refer to it later, you don't use the dot syntax

  render () {
    return (
      <option data-img-src={this.props.dataImgSrc} >...</option>
    )
  }
}

Mainly just realize data- attributes and aria- attributes are treated specially. You are allowed to use hyphens in the attribute name in those two cases.

Accordingly to this answer and to this video new keyword does next things:

1. Creates new object.

2. Links new object to constructor function (prototype).

3. Makes this variable point to the new object.

4. Executes constructor function using the new object and implicit perform return this;

5. Assigns constructor function name to new object's property constructor.

Object.create performs only 1st and 2nd steps!!!

I was looking for answers. I found only one.

None of these work for me. I am not trying to write temporary files, unless this is defined as nonsystem files. Although I am designated the admin on my user profile, with full admin rights indicated in the UAC, I cannot write to program files or windows. This is very irritating.

I try to save an image found online directly to the windows/web/wallpaper folder and it won't let me. Instead, I must save it to my desktop (I REFUSE to navigate to "my documents/pictures/etc" as I refuse to USE such folders, I have my own directory tree thank you) then, from the desktop, cut and paste it to the windows/web/wallpaper folder. And you are telling me I should do that and smile? As an admin user, I SHOULD be able to save directly to its destination folder. My permissions in drive properties/security and in directory properties/security say I can write, but I can't. Not to program files, program files (86) and windows.

How about saving a file I just modified for a game in Program Files (86) (name of game) folder. It won't let me. I open the file to modify it, I can't save it without first either saving it to desktop etc as above, or opening the program which is used for modifying the file first as admin, which means first navigating all the way over to another part of the directory tree where I store those user mod programs, then within the program selecting to open file and navigate again to the file I could have just clicked on to modify in the first place from my projects folder, only to discover that this won't work either! It saves the file, but the file cannot be located. It is there, but invisible. The only solution is to save to desktop as above.

I shouldn't have to do all this as an admin user. However, if I use the true admin account all works fine. But I don't want to use the real admin account. I want to use a user account with admin rights. It says I have admin rights, but I don't.

And, finally, I refuse to store my portables in %appdata%. This is not how I wish to navigate through my directory tree. My personal installations which I use as portables are stored in the directory I create as a navigation preference.

So, here is the tried and true answer I have found:

From what I have seen so far.... unless one uses the real admin account, these permissions just aren't ever really available to any other user with admin privileges in the Windows Vista and Windows 7 OS's. While it was simple to set admin privileges in Windows XP, later versions have taken this away for all but those who can comfortably hack around.

An established connection was aborted by the software in your host machine

That is a boiler-plate error message, it comes out of Windows. The underlying error code is WSAECONNABORTED. Which really doesn't mean more than "connection was aborted". You have to be a bit careful about the "your host machine" part of the phrase. In the vast majority of Windows application programs, it is indeed the host that the desktop app is connected to that aborted the connection. Usually a server somewhere else.

The roles are reversed however when you implement your own server. Now you need to read the error message as "aborted by the application at the other end of the wire". Which is of course not uncommon when you implement a server, client programs that use your server are not unlikely to abort a connection for whatever reason. It can mean that a fire-wall or a proxy terminated the connection but that's not very likely since they typically would not allow the connection to be established in the first place.

You don't really know why a connection was aborted unless you have insight what is going on at the other end of the wire. That's of course hard to come by. If your server is reachable through the Internet then don't discount the possibility that you are being probed by a port scanner. Or your customers, looking for a game cheat.

You are probably printing from a signed char array. Either print from an unsigned char array or mask the value with 0xff: e.g. ar[i] & 0xFF. The c0 values are being sign extended because the high (sign) bit is set.

The problem is your dataType and the format of your data parameter. I just tested this in a sandbox and the following works:

C#

    [HttpPost]
    public string ConvertLogInfoToXml(string jsonOfLog)
    {
        return Convert.ToString(jsonOfLog);
    }

javascript

<input type="button" onclick="test()"/>

    <script type="text/javascript">

        function test() {
            data = { prop: 1, myArray: [1, "two", 3] };
            //'data' is much more complicated in my real application
            var jsonOfLog = JSON.stringify(data);

            $.ajax({
                type: 'POST',
                dataType: 'text',
                url: "Home/ConvertLogInfoToXml",
                data: "jsonOfLog=" + jsonOfLog,
                success: function (returnPayload) {
                    console && console.log("request succeeded");
                },
                error: function (xhr, ajaxOptions, thrownError) {
                    console && console.log("request failed");
                },

                processData: false,
                async: false
            });
        }

    </script>

Pay special attention to data, when sending text, you need to send a variable that matches the name of your parameter. It's not pretty, but it will get you your coveted unformatted string.

When running this, jsonOfLog looks like this in the server function:

this.listView.setEmptyView(findViewById(R.id.emptyElement));

The percentage % sign followed by two hexadecimal numbers (UTF-8 character representation) typically denotes a string which has been encoded to be part of a URI. This ensures that characters that would otherwise have special meaning don't interfere. In your case %20 is immediately recognisable as a whitespace character - while not really having any meaning in a URI it is encoded in order to avoid breaking the string into multiple "parts".

Don't get me wrong, regex is the bomb! However any web technology worth caring about will already have tools available in it's library to handle standards like this for you. Why re-invent the wheel...?

var str = 'xPasswords%20do%20not%20match';
console.log( decodeURI(str) ); // "xPasswords do not match"

Javascript has both decodeURI and decodeURIComponent which differ slightly in respect to their encodeURI and encodeURIComponent counterparts - you should familiarise yourself with the documentation.

1) Create libs folder under project root
2) Copy and paste the jar file into it
3) Configure the build path (Add jar)
4) Clean and run

test.Substring(test.LastIndexOf("-"))

Keep in mind you'll also have to give the IUSR account write access for the folder once you upload to your web server.

Personally I recommend not allowing write access to the root folder unless you have a good reason for doing so. And then you need to be careful what sort of files you allow to be saved so you don't inadvertently allow someone to write their own ASPX pages.

HttpParams is deprecated in the new Apache HTTPClient library. Using the code provided by Laz leads to deprecation warnings.

I suggest to use RequestConfig instead on your HttpGet or HttpPost instance:

final RequestConfig params = RequestConfig.custom().setConnectTimeout(3000).setSocketTimeout(3000).build();
httpPost.setConfig(params);

Don't use int. Files over 2 gigabytes in size are common as dirt these days

Don't use unsigned int. Files over 4 gigabytes in size are common as some slightly-less-common dirt

IIRC the standard library defines off_t as an unsigned 64 bit integer, which is what everyone should be using. We can redefine that to be 128 bits in a few years when we start having 16 exabyte files hanging around.

If you're on windows, you should use GetFileSizeEx - it actually uses a signed 64 bit integer, so they'll start hitting problems with 8 exabyte files. Foolish Microsoft! :-)

I usually start out with some combination of:

typeof(obj)
class(obj)
sapply(obj, class)
sapply(obj, attributes)
attributes(obj)
names(obj)

as appropriate based on what's revealed. For example, try with:

obj <- data.frame(a=1:26, b=letters)
obj <- list(a=1:26, b=letters, c=list(d=1:26, e=letters))
data(cars)
obj <- lm(dist ~ speed, data=cars)

..etc.

If obj is an S3 or S4 object, you can also try methods or showMethods, showClass, etc. Patrick Burns' R Inferno has a pretty good section on this (sec #7).

EDIT: Dirk and Hadley mention str(obj) in their answers. It really is much better than any of the above for a quick and even detailed peek into an object.

putting a quick example, should be a sufficient starting point

Code in Form A

public event EventHandler<EventArgs> RowAdded;

private void btnRowAdded_Click(object sender, EventArgs e)
{
     // insert data
     // if successful raise event
     OnRowAddedEvent();
}

private void OnRowAddedEvent()
{
     var listener = RowAdded;
     if (listener != null)
         listener(this, EventArgs.Empty);
}

Code in Form B

private void button1_Click(object sender, EventArgs e)
{
     var frm = new Form2();
     frm.RowAdded += new EventHandler<EventArgs>(frm_RowAdded);
     frm.Show();
}

void frm_RowAdded(object sender, EventArgs e)
{
     // retrieve data again
}

You can even consider creating your own EventArgs class that can contain the newly added data. You can then use this to directly add the data to a new row in DatagridView

The method is implicitly defined (i.e. generated by the compiler).

From the JLS:

In addition, if E is the name of an enum type, then that type has the following implicitly declared static methods:

/**
* Returns an array containing the constants of this enum 
* type, in the order they're declared.  This method may be
* used to iterate over the constants as follows:
*
*    for(E c : E.values())
*        System.out.println(c);
*
* @return an array containing the constants of this enum 
* type, in the order they're declared
*/
public static E[] values();

/**
* Returns the enum constant of this type with the specified
* name.
* The string must match exactly an identifier used to declare
* an enum constant in this type.  (Extraneous whitespace 
* characters are not permitted.)
* 
* @return the enum constant with the specified name
* @throws IllegalArgumentException if this enum type has no
* constant with the specified name
*/
public static E valueOf(String name);

Oracle 10g Express Edition ships with Oracle Application Express (Apex) built-in. You're running this in its SQL Commands window, which doesn't support SQL*Plus syntax.

That doesn't matter, because (as you have discovered) the BEGIN...END syntax does work in Apex.

From Django docs:

The include tag should be considered as an implementation of "render this subtemplate and include the HTML", not as "parse this subtemplate and include its contents as if it were part of the parent". This means that there is no shared state between included templates -- each include is a completely independent rendering process.

So Django doesn't grab any blocks from your commondata.html and it doesn't know what to do with rendered html outside blocks.

Since PyYAML's yaml.load() function parses YAML documents to native Python data structures, you can just access items by key or index. Using the example from the question you linked:

import yaml
with open('tree.yaml', 'r') as f:
    doc = yaml.load(f)

To access branch1 text you would use:

txt = doc["treeroot"]["branch1"]
print txt
"branch1 text"

because, in your YAML document, the value of the branch1 key is under the treeroot key.

I have taken this and various other comments and created a bit more advanced function for running an application and getting the output.

Example to Call Function: Will output the DIR list of C:\ for Directories only. The output will be returned to the variable CommandResults as well as remain in C:\OUTPUT.TXT.

CommandResults = vFn_Sys_Run_CommandOutput("CMD.EXE /C DIR C:\ /AD",1,1,"C:\OUTPUT.TXT",0,1)

Function

Function vFn_Sys_Run_CommandOutput (Command, Wait, Show, OutToFile, DeleteOutput, NoQuotes)
'Run Command similar to the command prompt, for Wait use 1 or 0. Output returned and
'stored in a file.
'Command = The command line instruction you wish to run.
'Wait = 1/0; 1 will wait for the command to finish before continuing.
'Show = 1/0; 1 will show for the command window.
'OutToFile = The file you wish to have the output recorded to.
'DeleteOutput = 1/0; 1 deletes the output file. Output is still returned to variable.
'NoQuotes = 1/0; 1 will skip wrapping the command with quotes, some commands wont work
'                if you wrap them in quotes.

Vanilla JS solution:

var el = document.getElementById('changeProgramatic');
el.value='New Value'
el.dispatchEvent(new Event('change'));

Note that dispatchEvent doesn't work in old IE (see: caniuse). So you should probably only use it on internal websites (not on websites having wide audience).

So as of 2019 you just might want to make sure your customers/audience don't use Windows XP (yes, some still do in 2019). You might want to use conditional comments to warn customers that you don't support old IE (pre IE 11 in this case), but note that conditional comments only work until IE9 (don't work in IE10). So you might want to use feature detection instead. E.g. you could do an early check for: typeof document.body.dispatchEvent === 'function'.

do like this:

departments: string[]=[];
if(this.departments.indexOf(this.departmentName.trim()) >-1 ){
            return;
    }

Check to see if you have previously disabled caching in Chrome when the developer console is open - the setting is under the console, settings icon > General tab: Disable cache (while DevTools is open)

Use Callable instead of Thread, then you can call Future#get() which throws any exception that the Callable threw.

public class Example extends JFrame {

public static final int WIDTH = 550;//Any Size
public static final int HEIGHT = 335;//Any Size

public Example(){

      init();

}

private void init() {

    try {
        UIManager
                .setLookAndFeel("com.sun.java.swing.plaf.nimbus.NimbusLookAndFeel");

        SwingUtilities.updateComponentTreeUI(this);
        Dimension dimension = Toolkit.getDefaultToolkit().getScreenSize();
        setSize(WIDTH, HEIGHT);

        setLocation((int) (dimension.getWidth() / 2 - WIDTH / 2),
                (int) (dimension.getHeight() / 2 - HEIGHT / 2));


    } catch (ClassNotFoundException e) {
        e.printStackTrace();
    } catch (InstantiationException e) {
        e.printStackTrace();
    } catch (IllegalAccessException e) {
        e.printStackTrace();
    } catch (UnsupportedLookAndFeelException e) {
        e.printStackTrace();
    }

}
}

I tried all the solution given here and none of them worked for me. In version 2019.1.3 I just clean & rebuild artifact and it worked; first do Build -> Build Artifacts... -> <select your artifact> -> Clean then click Build or Rebuild from same place.

For properties that need to be managed outside of the WAR:

<context:property-placeholder location="file:///C:/application.yml"/>

For example if inside application.yml are name and id

Then you can create bean in runtime inside xml spring

<bean id="id1" class="my.class.Item">
    <property name="name" value="${name}"/>
    <property name="id" value="${id}"/>
</bean>

Give your anonymous function a name, then:

$(window).on("resize", doResize);

We can check error & 404 statusCode, and use try {} catch (err) {}.

You can try this :

const req = new XMLHttpRequest();_x000D_
req.onreadystatechange = function() {_x000D_
    if (req.status == 404) {_x000D_
        console.log("404");_x000D_
        return false;_x000D_
    }_x000D_
_x000D_
    if (!(req.readyState == 4 && req.status == 200))_x000D_
        return false;_x000D_
_x000D_
    const json = (function(raw) {_x000D_
        try {_x000D_
            return JSON.parse(raw);_x000D_
        } catch (err) {_x000D_
            return false;_x000D_
        }_x000D_
    })(req.responseText);_x000D_
_x000D_
    if (!json)_x000D_
        return false;_x000D_
_x000D_
    document.body.innerHTML = "Your city : " + json.city + "<br>Your isp : " + json.org;_x000D_

I had the same problem while trying to consume net.tcp wcf service endpoint in a http asmx service.

As I saw no one wrote specific answer WHY is this problem occurring, but only how to be handled properly.

I've been struggling with it several days in a row and finally I found out where the problem comes from in my case.

Initially I thought that when you make a reference to a service the config file will be configured regarding security tag the same way as it's in the source, but that was not the case and I should take care of it manually. In my case I had only

<netTcpBinding>
    <binding name="NetTcpBinding_IAuthenticationLoggerService"
    </binding>
</netTcpBinding>`

Later I saw that the security part is missing and it should looks like this

<netTcpBinding>
    <binding name="NetTcpBinding_IAuthenticationLoggerService" transferMode="Buffered">
      <security mode="None">
        <transport clientCredentialType="None"/>
      </security>
    </binding>
  </netTcpBinding>

The second problem in my case was that I was using transferMode="Streamed" on my source WCF service and in the client I had nothing specific about it, which was bad, because the default transferMode is Buffered and it's important on both places source and client to be configured in the same way.

I know this question is old, but I thought of posting the answer anyway as it may help someone. The above solutions were failing in some edge cases, so we had to implement it in a way that handles iOS, Desktop, and other platforms separately.

function isSafari() {
    var ua = window.navigator.userAgent;
    var iOS = !!ua.match(/iP(ad|od|hone)/i);
    var hasSafariInUa = !!ua.match(/Safari/i);
    var noOtherBrowsersInUa = !ua.match(/Chrome|CriOS|OPiOS|mercury|FxiOS|Firefox/i)
    var result = false;
    if(iOS) { //detecting Safari in IOS mobile browsers
        var webkit = !!ua.match(/WebKit/i);
        result = webkit && hasSafariInUa && noOtherBrowsersInUa
    } else if(window.safari !== undefined){ //detecting Safari in Desktop Browsers
        result = true;
    } else { // detecting Safari in other platforms
        result = hasSafariInUa && noOtherBrowsersInUa
    }
    return result;
}

Sometimes the command

adb -s emulator-5554 emu kill

did not work on my CI servers or desktops, for unknown reason. I think on Windows it's OK to kill the process of qemu, just like

Taskkill /IM qemu-system-x86_64.exe /F /T

In your opinion, what do you think is going to be the fastest?

On Unix time.clock() measures the amount of CPU time that has been used by the current process, so it's no good for measuring elapsed time from some point in the past. On Windows it will measure wall-clock seconds elapsed since the first call to the function. On either system time.time() will return seconds passed since the epoch.

If you're writing code that's meant only for Windows, either will work (though you'll use the two differently - no subtraction is necessary for time.clock()). If this is going to run on a Unix system or you want code that is guaranteed to be portable, you will want to use time.time().

pd.unique returns the unique values from an input array, or DataFrame column or index.

The input to this function needs to be one-dimensional, so multiple columns will need to be combined. The simplest way is to select the columns you want and then view the values in a flattened NumPy array. The whole operation looks like this:

>>> pd.unique(df[['Col1', 'Col2']].values.ravel('K'))
array(['Bob', 'Joe', 'Bill', 'Mary', 'Steve'], dtype=object)

Note that ravel() is an array method that returns a view (if possible) of a multidimensional array. The argument 'K' tells the method to flatten the array in the order the elements are stored in the memory (pandas typically stores underlying arrays in Fortran-contiguous order; columns before rows). This can be significantly faster than using the method's default 'C' order.

An alternative way is to select the columns and pass them to np.unique:

>>> np.unique(df[['Col1', 'Col2']].values)
array(['Bill', 'Bob', 'Joe', 'Mary', 'Steve'], dtype=object)

There is no need to use ravel() here as the method handles multidimensional arrays. Even so, this is likely to be slower than pd.unique as it uses a sort-based algorithm rather than a hashtable to identify unique values.

The difference in speed is significant for larger DataFrames (especially if there are only a handful of unique values):

>>> df1 = pd.concat([df]*100000, ignore_index=True) # DataFrame with 500000 rows
>>> %timeit np.unique(df1[['Col1', 'Col2']].values)
1 loop, best of 3: 1.12 s per loop

>>> %timeit pd.unique(df1[['Col1', 'Col2']].values.ravel('K'))
10 loops, best of 3: 38.9 ms per loop

>>> %timeit pd.unique(df1[['Col1', 'Col2']].values.ravel()) # ravel using C order
10 loops, best of 3: 49.9 ms per loop

You may need to Provide access to profile folder for iis user.

1. right click on profile folder
2. go to security tab

4. give full control to "IIS_IUSRS" (IF THIS USER NOT EXISTS THEN CLICK ON ADD AND TYPE "IIS_IUSRS" AND CLICK ON "Check Names".

If you install the "cssnext" Post CSS plugin, then you can safely start using the syntax that you want to use right now.

Using cssnext will turn this:

}

Into this:

input:not([type="radio"]):not([type="checkbox"]) {
  /* css here */
}

basically hidden fields will be more useful and advantages to use with multi step form. we can use hidden fields to pass one step information to next step using hidden and keep it forwarding till the end step.

1. CSRF tokens.

Cross-site request forgery is a very common website vulnerability. Requiring a secret, user-specific token in all form submissions will prevent CSRF attacks since attack sites cannot guess what the proper token is and any form submissions they perform on the behalf of the user will always fail.

2. Save state in multi-page forms.

If you need to store what step in a multi-page form the user is currently on, use hidden input fields. The user doesn't need to see this information, so hide it in a hidden input field.

General rule: Use the field to store anything that the user doesn't need to see, but that you want to send to the server on form submission.

If you want to keep the path to the file and just remove the extension

>>> file = '/root/dir/sub.exten/file.data.1.2.dat'
>>> print ('.').join(file.split('.')[:-1])
/root/dir/sub.exten/file.data.1.2

Rename File using VB SCript.

1. Create Folder Source and Archive in D : Drive. [You can choose other drive but make change in code from D:\Source to C:\Source in case you create folder in C: Drive]
2. Save files in Source folder to be renamed.
3. Save below code and save it as .vbs e.g ChangeFileName.vbs

4. Run file and the file will be renamed with existing file name and current date

If using cmake for me none of the hacks of editing the files and linking worked so I compiled using the flags which specify the gcc/g++ version.
cmake -DCMAKE_C_COMPILER=gcc-6 -DCMAKE_CXX_COMPILER=g++-6 ..

Worked like charm.

Rename your file, commit the changes including the "deleted" file, and don't include the new (renamed) file.

Rename your file back.
