You are missing a parantheses in the denominator of your gaussian() function. As it is right now you divide by 2 and multiply with the variance (sig^2). But that is not true and as you can see of your plots the greater variance the more narrow the gaussian is - which is wrong, it should be opposit.

So just change the gaussian() function to:

def gaussian(x, mu, sig):
    return np.exp(-np.power(x - mu, 2.) / (2 * np.power(sig, 2.)))

sigma = sum(y*(x - mean)**2)

should be

sigma = np.sqrt(sum(y*(x - mean)**2))

Here's a nice easy way I found:

h <- hist(g, breaks = 10, density = 10,
          col = "lightgray", xlab = "Accuracy", main = "Overall") 
xfit <- seq(min(g), max(g), length = 40) 
yfit <- dnorm(xfit, mean = mean(g), sd = sd(g)) 
yfit <- yfit * diff(h$mids[1:2]) * length(g) 

lines(xfit, yfit, col = "black", lwd = 2)

In MATLAB R2015a or newer, it is no longer necessary (or advisable from a performance standpoint) to use fspecial followed by imfilter since there is a new function called imgaussfilt that performs this operation in one step and more efficiently.

The basic syntax:

B = imgaussfilt(A,sigma) filters image A with a 2-D Gaussian smoothing kernel with standard deviation specified by sigma.

The size of the filter for a given Gaussian standard deviation (sigam) is chosen automatically, but can also be specified manually:

B = imgaussfilt(A,sigma,'FilterSize',[3 3]);

The default is 2*ceil(2*sigma)+1.

Additional features of imgaussfilter are ability to operate on gpuArrays, filtering in frequency or spacial domain, and advanced image padding options. It looks a lot like IPP... hmmm. Plus, there's a 3D version called imgaussfilt3.

Can be done in one line:

-- the following expression calculates ==> max(@val1, @val2)
SELECT 0.5 * ((@val1 + @val2) + ABS(@val1 - @val2)) 

Edit: If you're dealing with very large numbers you'll have to convert the value variables into bigint in order to avoid an integer overflow.

I checked your XAML, it works fine - e.g. both labels have a gray foreground.
My guess is that you have some style which is affecting the way it looks...

Try moving your XAML to a brand-new window and see for yourself... Then, check if you have any themes or styles (in the Window.Resources for instance) which might be affecting the labels...

These lines Worked for me.

string[] lines = File.ReadAllLines(txtProxyListPath.Text);
var options = new ParallelOptions { MaxDegreeOfParallelism = Environment.ProcessorCount * 10 };
Parallel.ForEach(lines , options, (item) =>
{

});

mintt=input("How many seconds you want to time?:")
timer=int(mintt)
while (timer != 0 ):
    timer=timer-1

This work very good to time seconds.

In Terminal, type open -a Google\ Chrome

This will open Google Chrome application without any need to manipulate directories!

TL;DR

The object returned by range() is actually a range object. This object implements the iterator interface so you can iterate over its values sequentially, just like a generator, list, or tuple.

But it also implements the __contains__ interface which is actually what gets called when an object appears on the right hand side of the in operator. The __contains__() method returns a bool of whether or not the item on the left-hand-side of the in is in the object. Since range objects know their bounds and stride, this is very easy to implement in O(1).

Yes. From the DTD

<!ELEMENT table
     (caption?, (col*|colgroup*), thead?, tfoot?, (tbody+|tr+))>

So it expects one or more. It then goes on to say

Use multiple tbody sections when rules are needed between groups of table rows.

This is the answer, hope it helps someone :)

round(float("123.789"))

will give you an integer value, but a float type. With Python's duck typing, however, the actual type is usually not very relevant. This will also round the value, which you might not want. Replace 'round' with 'int' and you'll have it just truncated and an actual int. Like this:

int(float("123.789"))

But, again, actual 'type' is usually not that important.

If you just want to change file permissions, you want to be careful about using -R on chmod since it will change anything, files or folders. If you are doing a relative change (like adding write permission for everyone), you can do this:

sudo chmod -R a+w /var/www

But if you want to use the literal permissions of read/write, you may want to select files versus folders:

sudo find /var/www -type f -exec chmod 666 {} \;

(Which, by the way, for security reasons, I wouldn't recommend either of these.)

Or for folders:

sudo find /var/www -type d -exec chmod 755 {} \;

Try this query (replace t.eventsDate with e.eventsDate):

SELECT e FROM Events e WHERE e.eventsDate BETWEEN :startDate AND :endDate

values = ['A', 'B', 'C', 'D', 'E']
values[0] # returns 'A'
values[2] # returns 'C'
# etc.

I had same problem when installing Robot Framework 2.9.2 using the Windows installer version on Windows 7.

I could solve it installing the VC14 builds require to have the "Visual C++ Redistributable for Visual Studio 2015 x86 or x64 installed" from Microsoft website.

document.getElementById("elementID").scrollIntoView();

Same thing, but wrapping it in a function:

function scrollIntoView(eleID) {
   var e = document.getElementById(eleID);
   if (!!e && e.scrollIntoView) {
       e.scrollIntoView();
   }
}

This even works in an IFrame on an iPhone.

Example of using getElementById: http://www.w3schools.com/jsref/tryit.asp?filename=tryjsref_document_getelementbyid

Specifying the range through visual selection is ok but when there are very simple operations over just a couple of lines that can be selected by an operator the best would be to apply these commands as operators.

This sadly can't be done through standards vim commands. You could do a sort of workaround using the ! (filter) operator and any text object. For example, to apply the operation to a paragraph, you can do:

!ip

This has to be read as "Apply the operator ! inside a paragraph". The filter operator starts command mode and automatically insert the range of lines followed by a literal "!" that you can delete just after. If you apply this, to the following paragraph:

1
2  Repellendus qui velit vel ullam!
3  ipsam sint modi! velit ipsam sint
4  modi! Debitis dolorum distinctio
5  mollitia vel ullam! Repellendus qui
6  Debitis dolorum distinctio mollitia
7  vel ullam! ipsam
8
9  More text around here

The result after pressing "!ap" would be like:

:.,.+5

As the '.' (point) means the current line, the range between the current line and the 5 lines after will be used for the operation. Now you can add the substitute command the same way as previously.

The bad part is that this is not easier that selecting the text for latter applying the operator. The good part is that this can repeat the insertion of the range for other similar text ranges (in this case, paragraphs) with sightly different size. I.e., if you later want to select the range bigger paragraph the '.' will to it right.

Also, if you like the idea of using semantic text objects to select the range of operation, you can check my plugin EXtend.vim that can do the same but in an easier manner.

ALTER TABLE can do multiple table alterations in one statement, but MODIFY COLUMN can only work on one column at a time, so you need to specify MODIFY COLUMN for each column you want to change:

ALTER TABLE webstore.Store
  MODIFY COLUMN ShortName VARCHAR(100),
  MODIFY COLUMN UrlShort VARCHAR(100);

Also, note this warning from the manual:

When you use CHANGE or MODIFY, column_definition must include the data type and all attributes that should apply to the new column, other than index attributes such as PRIMARY KEY or UNIQUE. Attributes present in the original definition but not specified for the new definition are not carried forward.

Hopefully this is self explanatory enough. Use the comments in the code to help understand what is happening. Pass a single cell to this function. The value of that cell will be the base file name. If the cell contains "AwesomeData" then we will try and create a file in the current users desktop called AwesomeData.pdf. If that already exists then try AwesomeData2.pdf and so on. In your code you could just replace the lines filename = Application..... with filename = GetFileName(Range("A1"))

Function GetFileName(rngNamedCell As Range) As String
    Dim strSaveDirectory As String: strSaveDirectory = ""
    Dim strFileName As String: strFileName = ""
    Dim strTestPath As String: strTestPath = ""
    Dim strFileBaseName As String: strFileBaseName = ""
    Dim strFilePath As String: strFilePath = ""
    Dim intFileCounterIndex As Integer: intFileCounterIndex = 1

    ' Get the users desktop directory.
    strSaveDirectory = Environ("USERPROFILE") & "\Desktop\"
    Debug.Print "Saving to: " & strSaveDirectory

    ' Base file name
    strFileBaseName = Trim(rngNamedCell.Value)
    Debug.Print "File Name will contain: " & strFileBaseName

    ' Loop until we find a free file number
    Do
        If intFileCounterIndex > 1 Then
            ' Build test path base on current counter exists.
            strTestPath = strSaveDirectory & strFileBaseName & Trim(Str(intFileCounterIndex)) & ".pdf"
        Else
            ' Build test path base just on base name to see if it exists.
            strTestPath = strSaveDirectory & strFileBaseName & ".pdf"
        End If

        If (Dir(strTestPath) = "") Then
            ' This file path does not currently exist. Use that.
            strFileName = strTestPath
        Else
            ' Increase the counter as we have not found a free file yet.
            intFileCounterIndex = intFileCounterIndex + 1
        End If

    Loop Until strFileName <> ""

    ' Found useable filename
    Debug.Print "Free file name: " & strFileName
    GetFileName = strFileName

End Function

The debug lines will help you figure out what is happening if you need to step through the code. Remove them as you see fit. I went a little crazy with the variables but it was to make this as clear as possible.

In Action

My cell O1 contained the string "FileName" without the quotes. Used this sub to call my function and it saved a file.

Sub Testing()
    Dim filename As String: filename = GetFileName(Range("o1"))

    ActiveWorkbook.Worksheets("Sheet1").Range("A1:N24").ExportAsFixedFormat Type:=xlTypePDF, _
                                              filename:=filename, _
                                              Quality:=xlQualityStandard, _
                                              IncludeDocProperties:=True, _
                                              IgnorePrintAreas:=False, _
                                              OpenAfterPublish:=False
End Sub

Where is your code located in reference to everything else? Perhaps you need to make a module if you have not already and move your existing code into there.

SELECT * FROM news WHERE date < DATEADD(Day, -1, date)

It sounds like you want to convert the rownames to a proper column of the data.frame. eg:

# add the rownames as a proper column
myDF <- cbind(Row.Names = rownames(myDF), myDF)
myDF

#           Row.Names id val vr2
# row_one     row_one  A   1  23
# row_two     row_two  A   2  24
# row_three row_three  B   3  25
# row_four   row_four  C   4  26

If you want to then remove the original rownames:

rownames(myDF) <- NULL
myDF
#   Row.Names id val vr2
# 1   row_one  A   1  23
# 2   row_two  A   2  24
# 3 row_three  B   3  25
# 4  row_four  C   4  26

Alternatively, if all of your data is of the same class (ie, all numeric, or all string), you can convert to Matrix and name the dimnames

myMat <- as.matrix(myDF)
names(dimnames(myMat)) <- c("Names.of.Rows", "")
myMat

# Names.of.Rows id  val vr2 
#   row_one   "A" "1" "23"
#   row_two   "A" "2" "24"
#   row_three "B" "3" "25"
#   row_four  "C" "4" "26"

In my case, I created a new ChildComponent in Parentcomponent whereas both in the same module but Parent is registered in a shared module so I created ChildComponent using CLI which registered Child in the current module but my parent was registered in the shared module.

So register the ChildComponent in Shared Module manually.

When you join the new thread in the main thread, it will wait until the thread finishes, so the GUI will block even though you are using multithreading.

If you want to place the logic portion in a different class, you can subclass Thread directly, and then start a new object of this class when you press the button. The constructor of this subclass of Thread can receive a Queue object and then you will be able to communicate it with the GUI part. So my suggestion is:

1. Create a Queue object in the main thread
2. Create a new thread with access to that queue
3. Check periodically the queue in the main thread

Then you have to solve the problem of what happens if the user clicks two times the same button (it will spawn a new thread with each click), but you can fix it by disabling the start button and enabling it again after you call self.prog_bar.stop().

import Queue

class GUI:
    # ...

    def tb_click(self):
        self.progress()
        self.prog_bar.start()
        self.queue = Queue.Queue()
        ThreadedTask(self.queue).start()
        self.master.after(100, self.process_queue)

    def process_queue(self):
        try:
            msg = self.queue.get(0)
            # Show result of the task if needed
            self.prog_bar.stop()
        except Queue.Empty:
            self.master.after(100, self.process_queue)

class ThreadedTask(threading.Thread):
    def __init__(self, queue):
        threading.Thread.__init__(self)
        self.queue = queue
    def run(self):
        time.sleep(5)  # Simulate long running process
        self.queue.put("Task finished")

Try to modify the eclipse.ini so that both Xms and Xmx are of the same value:

-Xms6000m
-Xmx6000m

This should force the Eclipse's VM to allocate 6GB of heap right from the beginning.

But be careful about either using the eclipse.ini or the command-line ./eclipse/eclipse -vmargs .... It should work in both cases but pick one and try to stick with it.

I think you can add the location of the file ssh-keygen.exe in the PATH environment variable. Follow the steps: Go to My Computer->Right click->Properties->Advanced System Settings->Click Environmental Variables. Now click PATH and then click EDIT. In the variable value field, go to the end and append ';C:\path\to\msysgit1.7.11\bin\ssh-keygen.exe' (without quotes)

You can just do:

@some_var.class == Hash

or also something like:

@some_var.is_a?(Hash)

It's worth noting that the "is_a?" method is true if the class is anywhere in the objects ancestry tree. for instance:

@some_var.is_a?(Object)  # => true

the above is true if @some_var is an instance of a hash or other class that stems from Object. So, if you want a strict match on the class type, using the == or instance_of? method is probably what you're looking for.

Maybe try this?

Arrays.asList() would do the trick here.

String[] words = {"ace", "boom", "crew", "dog", "eon"};   

List<String> wordList = Arrays.asList(words);  

For converting to Set, you can do as below

Set<T> mySet = new HashSet<T>(Arrays.asList(words));

SELECT CONVERT(CAST(column as BINARY) USING utf8) as column FROM table 

Simple and effective alternative:

public class ClassName
{
    public List<dynamic> MyProperty { get; set; }
}

or

public class ClassName
{
    public List<object> MyProperty { get; set; }
}

For differences see this post: List<Object> vs List<dynamic>

I believe your best shot is to declare the list as a list of objects:

List<Object> anything = new ArrayList<Object>();

Then you can put whatever you want in it, like:

anything.add(new Employee(..))

Evidently, you will not be able to read anything out of the list without a proper casting:

Employee mike = (Employee) anything.get(0);

I would discourage the use of raw types like:

List anything = new ArrayList()

Since the whole purpose of generics is precisely to avoid them, in the future Java may no longer suport raw types, the raw types are considered legacy and once you use a raw type you are not allowed to use generics at all in a given reference. For instance, take a look a this another question: Combining Raw Types and Generic Methods

Pointer Lock API

While the cursor: none CSS solution is definitely a solid and easy workaround, if your actual goal is to remove the default cursor while your web application is being used, or implement your own interpretation of raw mouse movement (for FPS games, for example), you might want to consider using the Pointer Lock API instead.

You can use requestPointerLock on an element to remove the cursor, and redirect all mousemove events to that element (which you may or may not handle):

document.body.requestPointerLock();

To release the lock, you can use exitPointerLock:

document.exitPointerLock();

Additional notes

No cursor, for real

This is a very powerful API call. It not only renders your cursor invisible, but it actually removes your operating system's native cursor. You won't be able to select text, or do anything with your mouse (except listening to some mouse events in your code) until the pointer lock is released (either by using exitPointerLock or pressing ESC in some browsers).

That is, you cannot leave the window with your cursor for it to show again, as there is no cursor.

Restrictions

As mentioned above, this is a very powerful API call, and is thus only allowed to be made in response to some direct user-interaction on the web, such as a click; for example:

document.addEventListener("click", function () {
    document.body.requestPointerLock();
});

Also, requestPointerLock won't work from a sandboxed iframe unless the allow-pointer-lock permission is set.

User-notifications

Some browsers will prompt the user for a confirmation before the lock is engaged, some will simply display a message. This means pointer lock might not activate right away after the call. However, the actual activation of pointer locking can be listened to by listening to the pointerchange event on the element on which requestPointerLock was called:

document.body.addEventListener("pointerlockchange", function () {
    if (document.pointerLockElement === document.body) {
        // Pointer is now locked to <body>.
    }
});

Most browsers will only display the message once, but Firefox will occasionally spam the message on every single call. AFAIK, this can only be worked around by user-settings, see Disable pointer-lock notification in Firefox.

Listening to raw mouse movement

The Pointer Lock API not only removes the mouse, but instead redirects raw mouse movement data to the element requestPointerLock was called on. This can be listened to simply by using the mousemove event, then accessing the movementX and movementY properties on the event object:

document.body.addEventListener("mousemove", function (e) {
    console.log("Moved by " + e.movementX + ", " + e.movementY);
});

You can use trap:

try { block A } catch { block B } finally { block C }

translates to:

(
  set -Ee
  function _catch {
    block B
    exit 0  # optional; use if you don't want to propagate (rethrow) error to outer shell
  }
  function _finally {
    block C
  }
  trap _catch ERR
  trap _finally EXIT
  block A
)

You can obfuscate the javascript source all you want, but it will always be reverse-engineerable just by virtue of requiring all the source code to actually run on the client machine... the best option I can think of is having all your processing done with server-side code, and all the client code javascript does is send requests for processing to the server itself. Otherwise, anyone will always be able to keep track of all operations that the code is doing.

Someone mentioned base64 to keep strings safe. This is a terrible idea. Base64 is immediately recognizable by the types of people who would want to reverse engineer your code. The first thing they'll do is unencode it and see what it is.

The easiest way to convert an ISO-8859-1 string to UTF-8 string.

private static String convertIsoToUTF8(String example) throws UnsupportedEncodingException {
    return new String(example.getBytes("ISO-8859-1"), "utf-8");
}

If we want to convert an UTF-8 string to ISO-8859-1 string.

private static String convertUTF8ToISO(String example) throws UnsupportedEncodingException {
    return new String(example.getBytes("utf-8"), "ISO-8859-1");
}

Moreover, a method that converts an ISO-8859-1 string to UTF-8 string without using the constructor of class String.

public static String convertISO_to_UTF8_personal(String strISO_8859_1) {
    String res = "";
    int i = 0;
    for (i = 0; i < strISO_8859_1.length() - 1; i++) {
        char ch = strISO_8859_1.charAt(i);
        char chNext = strISO_8859_1.charAt(i + 1);
        if (ch <= 127) {
            res += ch;
        } else if (ch == 194 && chNext >= 128 && chNext <= 191) {
            res += chNext;
        } else if(ch == 195 && chNext >= 128 && chNext <= 191){
            int resNum = chNext + 64;
            res += (char) resNum;
        } else if(ch == 194){
            res += (char) 173;
        } else if(ch == 195){
            res += (char) 224;
        }
    }
    char ch = strISO_8859_1.charAt(i);
    if (ch <= 127 ){
        res += ch;
    }
    return res;
}

}

That method is based on enconding utf-8 to iso-8859-1 of this website. Encoding utf-8 to iso-8859-1

You should really post your code^(a), but here goes. Start with something like:

    #include <stdio.h>
    #include <dirent.h>

    int main (int argc, char *argv[]) {
        struct dirent *pDirent;
        DIR *pDir;

        // Ensure correct argument count.

        if (argc != 2) {
            printf ("Usage: testprog <dirname>\n");
            return 1;
        }

        // Ensure we can open directory.

        pDir = opendir (argv[1]);
        if (pDir == NULL) {
            printf ("Cannot open directory '%s'\n", argv[1]);
            return 1;
        }

        // Process each entry.

        while ((pDirent = readdir(pDir)) != NULL) {
            printf ("[%s]\n", pDirent->d_name);
        }

        // Close directory and exit.

        closedir (pDir);
        return 0;
    }

You need to check in your case that args[1] is both set and refers to an actual directory. A sample run, with tmp is a subdirectory off my current directory but you can use any valid directory, gives me: testprog tmp

[.]
[..]
[file1.txt]
[file1_file1.txt]
[file2.avi]
[file2_file2.avi]
[file3.b.txt]
[file3_file3.b.txt]

Note also that you have to pass a directory in, not a file. When I execute:

testprog tmp/file1.txt

I get:

Cannot open directory 'tmp/file1.txt'

That's because it's a file rather than a directory (though, if you're sneaky, you can attempt to use diropen(dirname(argv[1])) if the initial diropen fails).

^(a) This has now been rectified but, since this answer has been accepted, I'm going to assume it was the issue of whatever you were passing in.

if you have given alies name change that to actual name

for example

SELECT  
    A.name,A.date
  FROM [LoginInfo].[dbo].[TableA] as A
   join 
  [LoginInfo].[dbo].[TableA] as B 
  on  [LoginInfo].[dbo].[TableA].name=[LoginInfo].[dbo].[TableB].name;

change that to

SELECT  
    A.name,A.date
  FROM [LoginInfo].[dbo].[TableA] as A
   join 
  [LoginInfo].[dbo].[TableA] as B 
  on  A.name=B.name;

I do not think that what you are looking for is provided by SciPy. I would write the code myself, in this situation.

The spline interpolation and smoothing from scipy.interpolate are quite nice and might be quite helpful in fitting peaks and then finding the location of their maximum.

Per Mozilla's Map documentation, you can initialize as follows:

private _gridOptions:Map<string, Array<string>> = 
    new Map([
        ["1", ["test"]],
        ["2", ["test2"]]
    ]);

Even cleaner would be to just put p#given img { float: right } in the style sheet, or in the <head> and wrapped in style tags. Then, just use the markdown ![Alt text](/path/to/img.jpg).

The accepted answer is very old.

I found a better modern answer here:

https://kevinmccarthy.org/2016/07/25/streaming-subprocess-stdin-and-stdout-with-asyncio-in-python/

and made some changes:

1. make it work on windows
2. make it work with multiple commands

import sys
import asyncio

if sys.platform == "win32":
    asyncio.set_event_loop_policy(asyncio.WindowsProactorEventLoopPolicy())


async def _read_stream(stream, cb):
    while True:
        line = await stream.readline()
        if line:
            cb(line)
        else:
            break


async def _stream_subprocess(cmd, stdout_cb, stderr_cb):
    try:
        process = await asyncio.create_subprocess_exec(
            *cmd, stdout=asyncio.subprocess.PIPE, stderr=asyncio.subprocess.PIPE
        )

        await asyncio.wait(
            [
                _read_stream(process.stdout, stdout_cb),
                _read_stream(process.stderr, stderr_cb),
            ]
        )
        rc = await process.wait()
        return process.pid, rc
    except OSError as e:
        # the program will hang if we let any exception propagate
        return e


def execute(*aws):
    """ run the given coroutines in an asyncio loop
    returns a list containing the values returned from each coroutine.
    """
    loop = asyncio.get_event_loop()
    rc = loop.run_until_complete(asyncio.gather(*aws))
    loop.close()
    return rc


def printer(label):
    def pr(*args, **kw):
        print(label, *args, **kw)

    return pr


def name_it(start=0, template="s{}"):
    """a simple generator for task names
    """
    while True:
        yield template.format(start)
        start += 1


def runners(cmds):
    """
    cmds is a list of commands to excecute as subprocesses
    each item is a list appropriate for use by subprocess.call
    """
    next_name = name_it().__next__
    for cmd in cmds:
        name = next_name()
        out = printer(f"{name}.stdout")
        err = printer(f"{name}.stderr")
        yield _stream_subprocess(cmd, out, err)


if __name__ == "__main__":
    cmds = (
        [
            "sh",
            "-c",
            """echo "$SHELL"-stdout && sleep 1 && echo stderr 1>&2 && sleep 1 && echo done""",
        ],
        [
            "bash",
            "-c",
            "echo 'hello, Dave.' && sleep 1 && echo dave_err 1>&2 && sleep 1 && echo done",
        ],
        [sys.executable, "-c", 'print("hello from python");import sys;sys.exit(2)'],
    )

    print(execute(*runners(cmds)))

It is unlikely that the example commands will work perfectly on your system, and it doesn't handle weird errors, but this code does demonstrate one way to run multiple subprocesses using asyncio and stream the output.

You can use these string functions,

strstr — Find the first occurrence of a string

stristr — Case-insensitive strstr()

strrchr — Find the last occurrence of a character in a string

strpos — Find the position of the first occurrence of a substring in a string

strpbrk — Search a string for any of a set of characters

If that doesn't help then you should use preg regular expression

preg_match — Perform a regular expression match

After looking for an answer for the question for months, I finally found a better solution: writing a simple script.

#!/usr/bin/expect

set timeout 20

set cmd [lrange $argv 1 end]
set password [lindex $argv 0]

eval spawn $cmd
expect "assword:"
send "$password\r";
interact

Put it to /usr/bin/exp, then you can use:

• exp <password> ssh <anything>
• exp <password> scp <anysrc> <anydst>

Done!

I had to use COUNTIF() in my case as part of my SELECT columns AND to mimic a % of the number of times each item appeared in my results.

So I used this...

SELECT COL1, COL2, ... ETC
       (1 / SELECT a.vcount 
            FROM (SELECT vm2.visit_id, count(*) AS vcount 
                  FROM dbo.visitmanifests AS vm2 
                  WHERE vm2.inactive = 0 AND vm2.visit_id = vm.Visit_ID 
                  GROUP BY vm2.visit_id) AS a)) AS [No of Visits],
       COL xyz
FROM etc etc

Of course you will need to format the result according to your display requirements.

You can use the Range object in VBA to set the value of a named cell, just like any other cell.

Range("C1").Value = Inputbox("Which job number would you like to add to the list?)

Where "C1" is the name of the cell you want to update.

My Excel VBA is a little bit old and crusty, so there may be a better way to do this in newer versions of Excel.

You can simply use CSS transitions, see this fiddle

.on {
color:#fff;
transition:all 1s;
}

.off{
color:#000;
transition:all 1s;
}

Yes it is possible in theory as defined by the specification. However there is no practical implementation as yet that would allow this.

Refer: NFC Forum Connection Handover Technical Specification http://www.nfc-forum.org/specs/spec_list/

Quoting from the specification regarding the security - "The Handover Protocol requires transmission of network access data and credentials (the carrier configuration data) to allow one device to connect to a wireless network provided by another device. Because of the close proximity needed for communication between NFC Devices and Tags, eavesdropping of carrier configuration data is difficult, but not impossible, without recognition by the legitimate owner of the devices. Transmission of carrier configuration data to devices that can be brought to close proximity is deemed legitimate within the scope of this specification."

I gave up the calculations and simply get the size of the view where I want the camera preview displayed and set the camera's preview size the same (just flipped width/height due to rotation) in my custom SurfaceView implementation:

@Override // CameraPreview extends SurfaceView implements SurfaceHolder.Callback { 
public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) {

    Display display = ((WindowManager) getContext().getSystemService(
            Context.WINDOW_SERVICE)).getDefaultDisplay();

    if (display.getRotation() == Surface.ROTATION_0) {
        final Camera.Parameters params = camera.getParameters();
        // viewParams is from the view where the preview is displayed
        params.setPreviewSize(viewParams.height, viewParams.width);
        camera.setDisplayOrientation(90);
        requestLayout();
        camera.setParameters(params);
    }
    // I do not enable rotation, so this can otherwise stay as is
}

Ok, so here was my process:

keytool -list -v -keystore permanent.jks - got me the alias.

keytool -export -alias alias_name -file certificate_name -keystore permanent.jks - got me the certificate to import.

Then I could import it with the keytool:

keytool -import -alias alias_name -file certificate_name -keystore keystore location

As @Christian Bongiorno says the alias can't already exist in your keystore.

As you've already noticed svn log command ran without any arguments shows all log messages that relate to the URL you specify or to the working copy folder where you run the command.

You can always refine/limit the svn log results:

• svn log --limit NUM will show only the first NUM of revisions,
• svn log --revision REV1(:REV2) will show the log message for REV1 revision or for REV1 -- REV2 range,
• svn log --search will show revisions that match the search pattern you specify (the command is available in Subversion 1.8 and newer client). You can search by
  • revision's author (i.e. committers username),
  • date when the revision was committed,
  • revision comment text (log message),
  • list of paths changed in revision.

You're doing things in the wrong order.

You need to first add all JComponents to the JFrame, and only then call pack() and then setVisible(true) on the JFrame

If you later added JComponents that could change the GUI's size you will need to call pack() again, and then repaint() on the JFrame after doing so.

Assuming this example HTML:

<input type="text" name="email" id="email" />
<input type="text" name="first_name" id="first_name" />
<input type="text" name="last_name" id="last_name" />

You could have this javascript:

$("#email").bind("change", function(e){
  $.getJSON("http://yourwebsite.com/lokup.php?email=" + $("#email").val(),
        function(data){
          $.each(data, function(i,item){
            if (item.field == "first_name") {
              $("#first_name").val(item.value);
            } else if (item.field == "last_name") {
              $("#last_name").val(item.value);
            }
          });
        });
});

Then just you have a PHP script (in this case lookup.php) that takes an email in the query string and returns a JSON formatted array back with the values you want to access. This is the part that actually hits the database to look up the values:

<?php
//look up the record based on email and get the firstname and lastname
...

//build the JSON array for return
$json = array(array('field' => 'first_name', 
                    'value' => $firstName), 
              array('field' => 'last_name', 
                    'value' => $last_name));
echo json_encode($json );
?>

You'll want to do other things like sanitize the email input, etc, but should get you going in the right direction.

I got this working : -

$.get('api.php', 'client=mikescafe', function(data) {
...
});

It sends via get the string ?client=mikescafe then collect this variable in api.php, and use it in your mysql statement.

You can use

var modal_template_html = $.trim($('#modal_template').html());
var template = $(modal_template_html);

The condition should be,

if number == 10000 and number <= 30000:
     print("5% tax payable")

reason for using number == 10000 is that if number's value is 50000 and if we use number >= 10000 the condition will pass, which is not what you want.

First rule of threading - "Threading is fun"...

I'm not able to understand the flow of execution of the program, And when ob1 is created then the constructor is called where t.start() is written but still run() method is not executed rather main() method continues execution. So why is this happening?

This is exactly what should happen. When you call Thread#start, the thread is created and schedule for execution, it might happen immediately (or close enough to it), it might not. It comes down to the thread scheduler.

This comes down to how the thread execution is scheduled and what else is going on in the system. Typically, each thread will be given a small amount of time to execute before it is put back to "sleep" and another thread is allowed to execute (obviously in multiple processor environments, more than one thread can be running at time, but let's try and keep it simple ;))

Threads may also yield execution, allow other threads in the system to have chance to execute.

You could try

NewThread(String threadname) {
    name = threadname;
    t = new Thread(this, name);
    System.out.println("New thread: " + t);
    t.start(); // Start the thread
    // Yield here
    Thread.yield();
}

And it might make a difference to the way the threads run...equally, you could sleep for a small period of time, but this could cause your thread to be overlooked for execution for a period of cycles (sometimes you want this, sometimes you don't)...

join() method is used to wait until the thread on which it is called does not terminates, but here in output we see alternate outputs of the thread why??

The way you've stated the question is wrong...join will wait for the Thread it is called on to die before returning. For example, if you depending on the result of a Thread, you could use join to know when the Thread has ended before trying to retrieve it's result.

Equally, you could poll the thread, but this will eat CPU cycles that could be better used by the Thread instead...

I use this:

gridItems = this.state.applications.map(app =>
          <ApplicationItem key={app.Id} app={app } />
);

PS: never forget the key or you will have a lot of warnings!

With [ChildActionOnly] attribute annotated, an action method can be called only as a child method from within a view. Here is an example for [ChildActionOnly]..

there are two action methods: Index() and MyDateTime() and corresponding Views: Index.cshtml and MyDateTime.cshtml. this is HomeController.cs

public class HomeController : Controller
 {
    public ActionResult Index()
    {
        ViewBag.Message = "This is from Index()";
        var model = DateTime.Now;
        return View(model);
    }

    [ChildActionOnly]
    public PartialViewResult MyDateTime()
    {
        ViewBag.Message = "This is from MyDateTime()";

        var model = DateTime.Now;
        return PartialView(model);
    } 
}

Here is the view for Index.cshtml.

@model DateTime
@{
    ViewBag.Title = "Index";
}
<h2>
    Index</h2>
<div>
    This is the index view for Home : @Model.ToLongTimeString()
</div>
<div>
    @Html.Action("MyDateTime")  // Calling the partial view: MyDateTime().
</div>

<div>
    @ViewBag.Message
</div>

Here is MyDateTime.cshtml partial view.

@model DateTime

<p>
This is the child action result: @Model.ToLongTimeString()
<br />
@ViewBag.Message
</p>

 if you run the application and do this request http://localhost:57803/home/mydatetime
 The result will be Server Error like so: 

This means you can not directly call the partial view. but it can be called via Index() view as in the Index.cshtml

     @Html.Action("MyDateTime")  // Calling the partial view: MyDateTime().
 

If you remove [ChildActionOnly] and do the same request http://localhost:57803/home/mydatetime it allows you to get the mydatetime partial view result:

This is the child action result. 12:53:31 PM 
This is from MyDateTime()

It seems you may be more comfortable with developing in PHP you let this hold you back from utilizing the full potential with web applications.

It is indeed possible to have PHP render partials and whole views, but I would not recommend it.

To fully utilize the possibilities of HTML and javascript to make a web application, that is, a web page that acts more like an application and relies heavily on client side rendering, you should consider letting the client maintain all responsibility of managing state and presentation. This will be easier to maintain, and will be more user friendly.

I would recommend you to get more comfortable thinking in a more API centric approach. Rather than having PHP output a pre-rendered view, and use angular for mere DOM manipulation, you should consider having the PHP backend output the data that should be acted upon RESTFully, and have Angular present it.

Using PHP to render the view:

/user/account

if($loggedIn)
{
    echo "<p>Logged in as ".$user."</p>";
}
else
{
    echo "Please log in.";
}

How the same problem can be solved with an API centric approach by outputting JSON like this:

api/auth/

{
  authorized:true,
  user: {
      username: 'Joe', 
      securityToken: 'secret'
  }
}

and in Angular you could do a get, and handle the response client side.

$http.post("http://example.com/api/auth", {})
.success(function(data) {
    $scope.isLoggedIn = data.authorized;
});

To blend both client side and server side the way you proposed may be fit for smaller projects where maintainance is not important and you are the single author, but I lean more towards the API centric way as this will be more correct separation of conserns and will be easier to maintain.

The easier way to do it is just:

ul li:after {
    content: url('../images/small_triangle.png');
}

As mentioned in the comments, this answer breaks encapsulation and tightly couples components, which is very likely not what you want. The best solution is probably making your object Parcelable or Serializable, as other responses explain. Having said that, the solution solves the problem. So if you know what you are doing:

Use a class with static fields:

public class Globals {
    public static Customer customer = new Customer();
}

Inside the activities you can use:

Activity From:

Globals.customer = myCustomerFromActivity;

Activity Target:

myCustomerTo = Globals.customer;

It's an easy way to pass information for activities.

<div id="outer" style="z-index:10000;width:99%;height:200px;margin-top:300px;margin-left:auto;margin-right:auto;float:left;position:absolute;opacity:0.9;">

<div id="inner" style="opacity:1;background-color:White;width:300px;height:200px;margin-left:auto;margin-right:auto;">Inner</div></div>

Float the div in the background to the max width, set a div inside that that's not transparent and center it using margin auto.

You can use imshow() method from matplotlib

import pandas as pd
import matplotlib.pyplot as plt
plt.style.use('ggplot')

plt.imshow(X.corr(), cmap=plt.cm.Reds, interpolation='nearest')
plt.colorbar()
tick_marks = [i for i in range(len(X.columns))]
plt.xticks(tick_marks, X.columns, rotation='vertical')
plt.yticks(tick_marks, X.columns)
plt.show()

pop'n'fresh

>>>a = {1:2, 3:4}
>>>a[5] = a.pop(1)
>>>a
{3: 4, 5: 2}
>>> 

You're trying to create a tuple, but you're just parenthesizing a string :)

Add an extra ',':

dRecieved = connFile.readline()
processThread = threading.Thread(target=processLine, args=(dRecieved,))  # <- note extra ','
processThread.start()

Or use brackets to make a list:

dRecieved = connFile.readline()
processThread = threading.Thread(target=processLine, args=[dRecieved])  # <- 1 element list
processThread.start()

If you notice, from the stack trace: self.__target(*self.__args, **self.__kwargs)

The *self.__args turns your string into a list of characters, passing them to the processLine function. If you pass it a one element list, it will pass that element as the first argument - in your case, the string.

I found this worked in my scenario.

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

$.get("urlToCheck.com").done(function () {
  alert("success");
}).fail(function () {
   alert("failed.");
});

Another tool is tcpmon. This is a java open-source tool to monitor a TCP connection. It's not directly a test server. It is placed in-between a client and a server but allow to see what is going through the "tube" and also to change what is going through.

Current Solution

Create the folder project/app/src/main/jniLibs, and then put your *.so files within their abi folders in that location. E.g.,

project/

+--src/
   +-- main/

I'm not familiar with either of these books, but the second is closer to current reality. The first may be discussing a specific processor.

Processors have been made with quite a variety of word sizes, not always a multiple of 8.

The 8086 and 8087 processors used 16 bit words, and it's likely this is the machine the first author was writing about.

More recent processors commonly use 32 or 64 bit words.

In the 50's and 60's there were machines with words sizes that seem quite strange to us now, such as 4, 9 and 36. Since about the 70's word size has commonly been a power of 2 and a multiple of 8.

Your script could be stopping, not because of the PHP timeout but because of the timeout in the browser you're using to access the script (ie. Firefox, Chrome, etc). Unfortunately there's seldom an easy way to extend this timeout, and in most browsers you simply can't. An option you have here is to access the script over a terminal. For example, on Windows you would make sure the PHP executable is in your path variable and then I think you execute:

C:\path\to\script> php script.php

Or, if you're using the PHP CGI, I think it's:

C:\path\to\script> php-cgi script.php

Plus, you would also set ini_set('max_execution_time', 0); in your script as others have mentioned. When running a PHP script this way, I'm pretty sure you can use buffer flushing to echo out the script's progress to the terminal periodically if you wish. The biggest issue I think with this method is there's really no way of stopping the script once it's started, other than stopping the entire PHP process or service.

Late response but this is what I ended up doing. If you want to run your curl commands very similarly as you run them on linux and you have windows 10 or latter do this:

    public static string ExecuteCurl(string curlCommand, int timeoutInSeconds=60)
    {
        if (string.IsNullOrEmpty(curlCommand))
            return "";

        curlCommand = curlCommand.Trim();

        // remove the curl keworkd
        if (curlCommand.StartsWith("curl"))
        {
            curlCommand = curlCommand.Substring("curl".Length).Trim();
        }

        // this code only works on windows 10 or higher
        {

            curlCommand = curlCommand.Replace("--compressed", "");

            // windows 10 should contain this file
            var fullPath = System.IO.Path.Combine(Environment.SystemDirectory, "curl.exe");

            if (System.IO.File.Exists(fullPath) == false)
            {
                if (Debugger.IsAttached) { Debugger.Break(); }
                throw new Exception("Windows 10 or higher is required to run this application");
            }

            // on windows ' are not supported. For example: curl 'http://ublux.com' does not work and it needs to be replaced to curl "http://ublux.com"
            List<string> parameters = new List<string>();


            // separate parameters to escape quotes
            try
            {
                Queue<char> q = new Queue<char>();

                foreach (var c in curlCommand.ToCharArray())

The reason why the code is a little bit long is because windows will give you an error if you execute a single quote. In other words, the command curl 'https://google.com' will work on linux and it will not work on windows. Thanks to that method I created you can use single quotes and run your curl commands exactly as you run them on linux. This code also checks for escaping characters such as \' and \".

For example use this code as

var output = ExecuteCurl(@"curl 'https://google.com' -H 'Accept: application/json, text/javascript, */*; q=0.01'");

If you where to run that same string agains C:\Windows\System32\curl.exe it will not work because for some reason windows does not like single quotes.

Wrap all those cases into one.

May use this-

#if defined CONDITION1 || defined CONDITION2
//your code here
#endif

This also does the same-

#if defined(CONDITION1) || defined(CONDITION2)
//your code here
#endif

Further-

• AND: #if defined CONDITION1 && defined CONDITION2
• XOR: #if defined CONDITION1 ^ defined CONDITION2
• AND NOT: #if defined CONDITION1 && !defined CONDITION2

If anybody still facing the error with using google's design library as mentioned in the answer then, please use this as commented by @h_k which is -

Instead of calling setError on TextInputLayout, You might be using setError on EditText itself.

function alertWithoutNotice(message){
    setTimeout(function(){
        alert(message);
    }, 1000);
}

My understanding is that this question is better answered over in this post.

But briefly, the answer to the OP with this method is simply:

s1 = pd.merge(df1, df2, how='inner', on=['user_id'])

Which gives s1 with 5 columns: user_id and the other two columns from each of df1 and df2.

Hopefully, it will work for you.

startActivityForResult( intent, 1 , ActivityOptions.makeCustomAnimation(getActivity(),R.anim.slide_out_bottom,R.anim.slide_in_bottom).toBundle());

The better way is with the calc() property. So your case would look like:

#myDiv {
    width: calc(100% - 5px);
    height: calc(100% - 5px);
    padding: 5px;
}

Simple, clean, no workarounds. Just make sure you don't forget the space between the values and the operator (eg (100%-5px) that will break the syntax. Enjoy!

Try looking in /etc/php5/conf.d/ to see if there is a file called xdebug.ini

max_nesting_level is 100 by default

If it is not set in that file add:

xdebug.max_nesting_level=300

to the end of the list so it looks like this

xdebug.remote_enable=on
xdebug.remote_handler=dbgp
xdebug.remote_host=localhost
xdebug.remote_port=9000
xdebug.profiler_enable=0
xdebug.profiler_enable_trigger=1
xdebug.profiler_output_dir=/home/drupalpro/websites/logs/profiler
xdebug.max_nesting_level=300

you can then use @Andrey's test before and after making this change to see if worked.

php -r 'function foo() { static $x = 1; echo "foo ", $x++, "\n"; foo(); } foo();'

Processing is new but very, very good.

This is works for me. tyr this

exec(“php asyn.php”.” > /dev/null 2>/dev/null &“);

HTML

<div id='a'>
  <div>
    <a class='click'>abc</a>
  </div>
</div>

You could use the XPATH as :

//div[@id='a']//a[@class='click']

output

<a class="click">abc</a>

That said your Python code should be as :

driver.find_element_by_xpath("//div[@id='a']//a[@class='click']")

In php.ini file

change this

;extension=php_mysql.dll

into

extension=php_mysql.dll

Use round() function.

round(2.607) = 3
round(2.607,2) = 2.61

Consider the case in which a service worker acts as an agnostic cache. Your only goal is serve the same resources that you would get from the network, but faster. Of course you can't ensure all the resources will be part of your origin (consider libraries served from CDNs, for instance). As the service worker has the potential of altering network responses, you need to guarantee you are not interested in the contents of the response, nor on its headers, nor even on the result. You're only interested on the response as a black box to possibly cache it and serve it faster.

This is what { mode: 'no-cors' } was made for.

assuming that string1 is your whole operation

use mdas

double result;
string recurAndCheck(string operation){
  if(operation.indexOf("/")){
     String leftSide = recurAndCheck(operation.split("/")[0]);
     string rightSide = recurAndCheck(operation.split("/")[1]);
     result = Double.parseDouble(leftSide)/Double.parseDouble(rightSide);

  } else if (..continue w/ *...) {
    //same as above but change / with *
  } else if (..continue w/ -) { 
    //change as above but change with -
  } else if (..continuew with +) {
    //change with add
  } else {
    return;
  }
}

If you've just created a new instance and can't connect to it, I was able to solve the issue by terminating that one and creating a new one. Of course this will only work if it's a new instance and you haven't done any more work on it.

Try

apt-get -d install <packages>

It is documented in man apt-get.

Just for clarification; the downloaded packages are located in the apt package cache at

Short 'n Sweet

function escapeRegExp(string) {
  return string.replace(/[.*+?^${}()|[\]\\]/g, '\\$&'); // $& means the whole matched string
}

Example

escapeRegExp("All of these should be escaped: \ ^ $ * + ? . ( ) | { } [ ]");

>>> "All of these should be escaped: \\ \^ \$ \* \+ \? \. \( \) \| \{ \} \[ \] "

(NOTE: the above is not the original answer; it was edited to show the one from MDN. This means it does not match what you will find in the code in the below npm, and does not match what is shown in the below long answer. The comments are also now confusing. My recommendation: use the above, or get it from MDN, and ignore the rest of this answer. -Darren,Nov 2019)

The Long Answer

If you're going to use the function above at least link to this stack overflow post in your code's documentation so that it doesn't look like crazy hard-to-test voodoo.

var escapeRegExp;

(function () {
  // Referring to the table here:
  // https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/regexp
  // these characters should be escaped
  // \ ^ $ * + ? . ( ) | { } [ ]
  // These characters only have special meaning inside of brackets
  // they do not need to be escaped, but they MAY be escaped
  // without any adverse effects (to the best of my knowledge and casual testing)
  // : ! , = 
  // my test "~!@#$%^&*(){}[]`/=?+\|-_;:'\",<.>".match(/[\#]/g)

  var specials = [
        // order matters for these
          "-"
        , "["
        , "]"
        // order doesn't matter for any of these
        , "/"
        , "{"
        , "}"
        , "("
        , ")"
        , "*"
        , "+"
        , "?"
        , "."
        , "\\"
        , "^"
        , "$"
        , "|"
      ]

      // I choose to escape every character with '\'
      // even though only some strictly require it when inside of []
    , regex = RegExp('[' + specials.join('\\') + ']', 'g')
    ;

  escapeRegExp = function (str) {
    return str.replace(regex, "\\$&");
  };

  // test escapeRegExp("/path/to/res?search=this.that")
}());

Edit Angular >= 4.3.x

HttpClient has been introduced along with HttpParams. Below an example of use :

import { HttpParams, HttpClient } from '@angular/common/http';

constructor(private http: HttpClient) { }

let params = new HttpParams();
params = params.append('var1', val1);
params = params.append('var2', val2);

this.http.get(StaticSettings.BASE_URL, {params: params}).subscribe(...);

(Old answers)

Edit Angular >= 4.x

requestOptions.search has been deprecated. Use requestOptions.params instead :

let requestOptions = new RequestOptions();
requestOptions.params = params;

Original answer (Angular 2)

You need to import URLSearchParams as below

import { Http, RequestOptions, URLSearchParams } from '@angular/http';

And then build your parameters and make the http request as the following :

let params: URLSearchParams = new URLSearchParams();
params.set('var1', val1);
params.set('var2', val2);

let requestOptions = new RequestOptions();
requestOptions.search = params;

this.http.get(StaticSettings.BASE_URL, requestOptions)
    .toPromise()
    .then(response => response.json())
...

If I want something like sed, then I usually just call sed itself using the sh library.

from sh import sed

sed(['-i', 's/^# deb/deb/', '/etc/apt/sources.list'])

Sure, there are downsides. Like maybe the locally installed version of sed isn't the same as the one you tested with. In my cases, this kind of thing can be easily handled at another layer (like by examining the target environment beforehand, or deploying in a docker image with a known version of sed).

you will need to use a PHP script (or an other server side language for this)

<?php
// We'll be outputting a PDF
header('Content-type: application/pdf');

// It will be called downloaded.pdf
header('Content-Disposition: attachment; filename="downloaded.pdf"');

// The PDF source is in original.pdf
readfile('original.pdf');
?>

and use httacces to redirect (rewrite) to the PHP file instead of the pdf

Your module name must be camelCase eg. pdfLib. I had same issue because I my module name was 'PdfLib' and after renaming it to 'pdfLib'. It worked. The issue was not in my device but in jenkins server. So, check and see if you have such modulenames

Why perform the summation forwards when you can do it backwards? Given:

std::vector<int> v;     // vector to be summed
int sum_of_elements(0); // result of the summation

We can use subscripting, counting backwards:

for (int i(v.size()); i > 0; --i)
    sum_of_elements += v[i-1];

We can use range-checked "subscripting," counting backwards (just in case):

for (int i(v.size()); i > 0; --i)
    sum_of_elements += v.at(i-1);

We can use reverse iterators in a for loop:

for(std::vector<int>::const_reverse_iterator i(v.rbegin()); i != v.rend(); ++i)
    sum_of_elements += *i;

We can use forward iterators, iterating backwards, in a for loop (oooh, tricky!):

for(std::vector<int>::const_iterator i(v.end()); i != v.begin(); --i)
    sum_of_elements += *(i - 1);

We can use accumulate with reverse iterators:

sum_of_elems = std::accumulate(v.rbegin(), v.rend(), 0);

We can use for_each with a lambda expression using reverse iterators:

std::for_each(v.rbegin(), v.rend(), [&](int n) { sum_of_elements += n; });

So, as you can see, there are just as many ways to sum the vector backwards as there are to sum the vector forwards, and some of these are much more exciting and offer far greater opportunity for off-by-one errors.

Text here:-
use this for getting activity context for progressdialog

 progressdialog = new ProgressDialog(Splash.this);

or progressdialog = new ProgressDialog(this);

use this for getting application context for BroadcastListener not for progressdialog.

progressdialog = new ProgressDialog(getApplicationContext());
progressdialog = new ProgressDialog(getBaseContext());

One solution is to use the idiosyncratic tools the platform offers:

private static String invokeLinuxPsProcess(String filterByCommand) {
    List<String> args = Arrays.asList("ps -e -o stat,pid,unit,args=".split(" +"));
    // Example output:
    // Sl   22245 bpds-api.service                /opt/libreoffice5.4/program/soffice.bin --headless
    // Z    22250 -                               [soffice.bin] <defunct>

    try {
        Process psAux = new ProcessBuilder(args).redirectErrorStream(true).start();
        try {
            Thread.sleep(100); // TODO: Find some passive way.
        } catch (InterruptedException e) { }

        try (BufferedReader reader = new BufferedReader(new InputStreamReader(psAux.getInputStream(), StandardCharsets.UTF_8))) {
            String line;
            while ((line = reader.readLine()) != null) {
                if (!line.contains(filterByCommand))
                    continue;
                String[] parts = line.split("\\w+");
                if (parts.length < 4)
                    throw new RuntimeException("Unexpected format of the `ps` line, expected at least 4 columns:\n\t" + line);
                String pid = parts[1];
                return pid;
            }
        }
    }
    catch (IOException ex) {
        log.warn(String.format("Failed executing %s: %s", args, ex.getMessage()), ex);
    }
    return null;
}

Disclaimer: Not tested, but you get the idea:

• Call ps to list the processes,
• Find your one because you know the command you launched it with.
• If there are multiple processes with the same command, you can:
  • Add another dummy argument to differentiate them
  • Rely on the increasing PID (not really safe, not concurrent)
  • Check the time of process creation (could be too coarse to really differentiate, also not concurrent)
  • Add a specific environment variable and list it with ps too.

You are pointing your JAVA_HOME to the JRE which is the Java Runtime Environment. The runtime environment doesn't have a java compiler in its bin folder. You should download the JDK which is the Java Development Kit. Once you've installed that, you can see in your bin folder that there's a file called javac.exe. That's your compiler.

To add on to Andrea's solution, if you are passing an array of JSONs for instance

[
    {"name":"value"},
    {"name":"value2"}
]

Then you will need to set up the Spring Boot Controller like so:

@RequestMapping(
    value = "/process", 
    method = RequestMethod.POST)
public void process(@RequestBody Map<String, Object>[] payload) 
    throws Exception {

    System.out.println(payload);

}

In terms of performance my favorite answer would be:

b.extend(a)

Check how the related alternatives compare with each other in terms of performance:

In [1]: import timeit

In [2]: timeit.timeit('b.extend(a)', setup='b=[];a=range(0,10)', number=100000000)
Out[2]: 9.623248100280762

In [3]: timeit.timeit('b = a[:]', setup='b=[];a=range(0,10)', number=100000000)
Out[3]: 10.84756088256836

In [4]: timeit.timeit('b = list(a)', setup='b=[];a=range(0,10)', number=100000000)
Out[4]: 21.46313500404358

In [5]: timeit.timeit('b = [elem for elem in a]', setup='b=[];a=range(0,10)', number=100000000)
Out[5]: 66.99795293807983

In [6]: timeit.timeit('for elem in a: b.append(elem)', setup='b=[];a=range(0,10)', number=100000000)
Out[6]: 67.9775960445404

In [7]: timeit.timeit('b = deepcopy(a)', setup='from copy import deepcopy; b=[];a=range(0,10)', number=100000000)
Out[7]: 1216.1108016967773

There are 2 possibilities.

You really don't have Label property.

You need to call appropriate GetProperty overload and pass the correct binding flags, e.g. BindingFlags.Public | BindingFlags.Instance

If your property is not public, you will need to use BindingFlags.NonPublic or some other combination of flags which fits your use case. Read the referenced API docs to find the details.

EDIT:

ooops, just noticed you call GetProperty on typeof(MyClass). typeof(MyClass) is Type which for sure has no Label property.

Thirding TagLib Sharp.

TagLib.File f = TagLib.File.Create(path);
f.Tag.Album = "New Album Title";
f.Save();

Your use case would be :

    $ArrayCollectionOfActiveUsers = $customer->users->filter(function($user) {
                        return $user->getActive() === TRUE;
                    });

if you add ->first() you'll get only the first entry returned, which is not what you want.

@ Sjwdavies You need to put () around the variable you pass to USE. You can also shorten as in_array return's a boolean already:

    $member->getComments()->filter( function($entry) use ($idsToFilter) {
        return in_array($entry->getId(), $idsToFilter);
    });

you can do this create a global "Menu" object then assign it in onCreateOptionMenu

public class ExampleActivity extends AppCompatActivity
    Menu menu;

then assign here

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.menu, menu);
    this.menu = menu;
    return true;
}

Then later use assigned Menu object to get required items

menu.findItem(R.id.bedSwitch).setTitle("Your Text");

Swift 3.x - 5.x

Necessary: import AVKit, import AVFoundation

AVFoundation framework is needed even if you use AVPlayer

If you want to use AVPlayerViewController:

let videoURL = URL(string: "https://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4")
let player = AVPlayer(url: videoURL!)
let playerViewController = AVPlayerViewController()
playerViewController.player = player
self.present(playerViewController, animated: true) {
    playerViewController.player!.play()
}

or just AVPlayer:

let videoURL = URL(string: "https://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4")
let player = AVPlayer(url: videoURL!)
let playerLayer = AVPlayerLayer(player: player)
playerLayer.frame = self.view.bounds
self.view.layer.addSublayer(playerLayer)
player.play()

It's better to put this code into the method: override func viewDidAppear(_ animated: Bool) or somewhere after.

Objective-C

AVPlayerViewController:

NSURL *videoURL = [NSURL URLWithString:@"https://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4"];
AVPlayer *player = [AVPlayer playerWithURL:videoURL];
AVPlayerViewController *playerViewController = [AVPlayerViewController new];
playerViewController.player = player;
[self presentViewController:playerViewController animated:YES completion:^{
  [playerViewController.player play];
}];

or just AVPlayer:

NSURL *videoURL = [NSURL URLWithString:@"https://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4"];
AVPlayer *player = [AVPlayer playerWithURL:videoURL];
AVPlayerLayer *playerLayer = [AVPlayerLayer playerLayerWithPlayer:player];
playerLayer.frame = self.view.bounds;
[self.view.layer addSublayer:playerLayer];
[player play];

You can use sys.platform.

Select ID, IsNull(Cast(ParentID as varchar(max)),'') from Patients

This is needed because field ParentID is not varchar/nvarchar type. This will do the trick:

Select ID, IsNull(ParentID,'') from Patients

A particular example: I have Java 7 and Java 6 installed, I need to run some builds with 6, others with 7. Therefore I need to dynamically alter JAVA_HOME so that maven picks up what I want for each build. I did the following:

• created j6.sh script which simply does export JAVA_HOME=... path to j6 install...
• then, as suggested by one of the comments above, whenever I need J6 for a build, I run source j6.sh in that respective command terminal. By default, my JAVA_HOME is set to J7.

Hope this helps.

Works perfectly with python 3.5+

client:

import requests
data = {'sender':   'Alice',
    'receiver': 'Bob',
    'message':  'We did it!'}
r = requests.post("http://localhost:8080", json={'json_payload': data})

server:

class Root(object):

    def __init__(self, content):
        self.content = content
        print self.content  # this works

    exposed = True

    def GET(self):
        cherrypy.response.headers['Content-Type'] = 'application/json'
        return simplejson.dumps(self.content)

    @cherrypy.tools.json_in()
    @cherrypy.tools.json_out()
    def POST(self):
        self.content = cherrypy.request.json
        return {'status': 'success', 'message': 'updated'}

Try this :

<script>
  window.jQuery || document.write('<script src="js/jquery.min.js"><\/script>')
</script>

This checks if jQuery is available or not, if not it will add one dynamically from path specified.

The standard way to add Multiple functions

<button (click)="removeAt(element.bookId); openDeleteDialog()"> Click Here</button>

or

<button (click)="removeAt(element.bookId)" (click)="openDeleteDialog()"> Click Here</button>

just use native javascript reload method:

reloadPage() {
    window.location.reload();
}

EDIT

To avoid this error : The specified type member 'Date' is not supported in LINQ to Entities. Only initializers, entity members, and entity navigation properties are supported.

var _My_ResetSet_Array = _DB
                .tbl_MyTable
                .Where(x => x.Active == true)
                         .Select(x => x).ToList();

 var filterdata = _My_ResetSet_Array
        .Where(x=>DateTime.Compare(x.DateTimeValueColumn.Date, DateTime.Now.Date)  <= 0 );

The second line is required because LINQ to Entity is not able to convert date property to sql query. So its better to first fetch the data and then apply the date filter.

EDIT

If you just want to compare the date value of the date time than make use of

DateTime.Date Property - Gets the date component of this instance.

Code for you

var _My_ResetSet_Array = _DB
                .tbl_MyTable
                .Where(x => x.Active == true
     && DateTime.Compare(x.DateTimeValueColumn.Date, DateTime.Now.Date)  <= 0 )
                         .Select(x => x);

If its like that then use

DateTime.Compare Method - Compares two instances of DateTime and returns an integer that indicates whether the first instance is earlier than, the same as, or later than the second instance.

Code for you

var _My_ResetSet_Array = _DB
                .tbl_MyTable
                .Where(x => x.Active == true
                  && DateTime.Compare(x.DateTimeValueColumn, DateTime.Now)  <= 0 )
                         .Select(x => x);

Example

DateTime date1 = new DateTime(2009, 8, 1, 0, 0, 0);
DateTime date2 = new DateTime(2009, 8, 1, 12, 0, 0);
int result = DateTime.Compare(date1, date2);
string relationship;

if (result < 0)
   relationship = "is earlier than";
else if (result == 0)
   relationship = "is the same time as";         
else
   relationship = "is later than";

The following Bash/zsh function splits its first argument on the delimiter given by the second argument:

split() {
    local string="$1"
    local delimiter="$2"
    if [ -n "$string" ]; then
        local part
        while read -d "$delimiter" part; do
            echo $part
        done <<< "$string"
        echo $part
    fi
}

For instance, the command

$ split 'a;b;c' ';'

yields

a
b
c

This output may, for instance, be piped to other commands. Example:

$ split 'a;b;c' ';' | cat -n
1   a
2   b
3   c

Compared to the other solutions given, this one has the following advantages:

• IFS is not overriden: Due to dynamic scoping of even local variables, overriding IFS over a loop causes the new value to leak into function calls performed from within the loop.

• Arrays are not used: Reading a string into an array using read requires the flag -a in Bash and -A in zsh.

If desired, the function may be put into a script as follows:

#!/usr/bin/env bash

split() {
    # ...
}

split "$@"

You can simply do this:

my $input_Color = 'Green';
my @array = qw(Red Blue Green Yellow Black);
@array = grep {!/$input_Color/} @array;
print "@array";

         //Store the number of days after which you want to delete the logs.
         int Days = 30;

          // Storing the path of the directory where the logs are stored.
           String DirPath = System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase).Substring(6) + "\\Log(s)\\";

          //Fetching all the folders.
            String[] objSubDirectory = Directory.GetDirectories(DirPath);

            //For each folder fetching all the files and matching with date given 
            foreach (String subdir in objSubDirectory)     
            {
                //Getting the path of the folder                 
                String strpath = Path.GetFullPath(subdir);
                //Fetching all the files from the folder.
                String[] strFiles = Directory.GetFiles(strpath);
                foreach (string files in strFiles)
                {
                    //For each file checking the creation date with the current date.
                    FileInfo objFile = new FileInfo(files);
                    if (objFile.CreationTime <= DateTime.Now.AddDays(-Days))
                    {
                        //Delete the file.
                        objFile.Delete();
                    }
                }

                //If folder contains no file then delete the folder also.
                if (Directory.GetFiles(strpath).Length == 0)
                {
                    DirectoryInfo objSubDir = new DirectoryInfo(subdir);
                    //Delete the folder.

solution : repository.findBySomeSetOfDataIn(setOfData);

I think you should use SO_LINGER options (with timeout 0). In this case, you connection will close immediately after closing your program; and next restart will be able to bind again.

example:

linger lin;
lin.l_onoff = 0;
lin.l_linger = 0;
setsockopt(fd, SOL_SOCKET, SO_LINGER, (const char *)&lin, sizeof(int));

see definition: http://man7.org/linux/man-pages/man7/socket.7.html

SO_LINGER
          Sets or gets the SO_LINGER option.  The argument is a linger
          structure.

              struct linger {
                  int l_onoff;    /* linger active */
                  int l_linger;   /* how many seconds to linger for */
              };

          When enabled, a close(2) or shutdown(2) will not return until
          all queued messages for the socket have been successfully sent
          or the linger timeout has been reached.  Otherwise, the call
          returns immediately and the closing is done in the background.
          When the socket is closed as part of exit(2), it always
          lingers in the background.

I've ran across this problem recently while trying to retrieve a null decimal from a DataTable object from db and I haven't seen this answer here. I find this easier and shorter:

var value = rdrSelect.Field<decimal?>("ColumnName") ?? 0;

This was useful in my case since i didn't have a nullable decimal in the model, but needed a quick check against one. If the db value happens to be null, it'll just assign the default value.

CSS Attribute selectors will allow you to check attributes for a string. (in this case - a class-name)

https://developer.mozilla.org/en-US/docs/Web/CSS/Attribute_selectors

(looks like it's actually at 'recommendation' status for 2.1 and 3)

Here's an outline of how I *think it works:

• [ ] : is the container for complex selectors if you will...
• class : 'class' is the attribute you are looking at in this case.
• * : modifier(if any): in this case - "wildcard" indicates you're looking for ANY match.
• test- : the value (assuming there is one) of the attribute - that contains the string "test-" (which could be anything)

So, for example:

[class*='test-'] {
  color: red;
}

You could be more specific if you have good reason, with the element too

ul[class*='test-'] > li { ... }

I've tried to find edge cases, but I see no need to use a combination of ^ and * - as * gets everything...

example: http://codepen.io/sheriffderek/pen/MaaBwp

http://caniuse.com/#feat=css-sel2

Everything above IE6 will happily obey. : )

note that:

[class] { ... }

Will select anything with a class...

If you are using .NET 3.5 or newer you can use LINQ extension methods to achieve a "contains" check with the Any extension method:

if(CartProducts.Any(prod => prod.ID == p.ID))

This will check for the existence of a product within CartProducts which has an ID matching the ID of p. You can put any boolean expression after the => to perform the check on.

This also has the benefit of working for LINQ-to-SQL queries as well as in-memory queries, where Contains doesn't.

To convert an String number to an Int, you should do this:

let stringNumber = "5"
let number = Int(stringNumber)

convert Map to POJO example.Notice the Map key contains underline and field variable is hump.

User.class POJO

import com.fasterxml.jackson.annotation.JsonProperty;
import lombok.Data;

@Data
public class User {
    @JsonProperty("user_name")
    private String userName;
    @JsonProperty("pass_word")
    private String passWord;
}

The App.class test the example

import java.util.HashMap;
import java.util.Map;

import com.fasterxml.jackson.databind.ObjectMapper;

public class App {
    public static void main(String[] args) {
        Map<String, String> info = new HashMap<>();
        info.put("user_name", "Q10Viking");
        info.put("pass_word", "123456");

        ObjectMapper mapper = new ObjectMapper();
        User user = mapper.convertValue(info, User.class);

        System.out.println("-------------------------------");
        System.out.println(user);
    }
}
/**output
-------------------------------
User(userName=Q10Viking, passWord=123456)
 */

Quick Overview: index and find

Next to the find method there is as well index. find and index both yield the same result: returning the position of the first occurrence, but if nothing is found index will raise a ValueError whereas find returns -1. Speedwise, both have the same benchmark results.

s.find(t)    #returns: -1, or index where t starts in s
s.index(t)   #returns: Same as find, but raises ValueError if t is not in s

Additional knowledge: rfind and rindex:

In general, find and index return the smallest index where the passed-in string starts, and rfind and rindex return the largest index where it starts Most of the string searching algorithms search from left to right, so functions starting with r indicate that the search happens from right to left.

So in case that the likelihood of the element you are searching is close to the end than to the start of the list, rfind or rindex would be faster.

s.rfind(t)   #returns: Same as find, but searched right to left
s.rindex(t)  #returns: Same as index, but searches right to left

    var scripts = '';
    var cleaned = text.replace(/<script[^>]*>([\s\S]*?)<\/script>/gi, function(){
        scripts += arguments[1] + '\n';
        return '';
    });

    if (window.execScript){
        window.execScript(scripts);
    } else {
        var head = document.getElementsByTagName('head')[0];
        var scriptElement = document.createElement('script');
        scriptElement.setAttribute('type', 'text/javascript');
        scriptElement.innerText = scripts;
        head.appendChild(scriptElement);
        head.removeChild(scriptElement);
    }
    return cleaned;
};


var scriptString = '<scrip' + 't + type="text/javascript">alert(\'test\');</scr' + 'ipt><strong>test</strong>';
document.getElementById('element').innerHTML = stripAndExecuteScript(scriptString);

I like this approach, it is visual for me.

using (var webClient = new WebClient())
    {
          var response = webClient.DownloadString(url);
          JObject result = JObject.Parse(response);
          var users = result.SelectToken("data");   
          List<User> userList = JsonConvert.DeserializeObject<List<User>>(users.ToString());
    }

as HTMLInputElement works for me

There is a special build-in util for this - 'yes'.

To answer all questions with the same answer, you can run

yes [answer] |./your_script

Or you can put it inside your script have specific answer to each question

This is all you have to do:

In front.inc

global $name;
$name = 'james';

Here is a shorter solution by AbacusUtil

Stream.of(input).toMap(e -> e.getKey().substring(subLength), 
                       e -> AttributeType.GetByName(e.getValue()));

Here's a trick to easily check if the schema already exists, and then create it, in it's own batch, to avoid the error message of trying to create a schema when it's not the only command in a batch.

IF NOT EXISTS (SELECT schema_name 
    FROM information_schema.schemata 
    WHERE schema_name = 'newSchemaName' )
BEGIN
    EXEC sp_executesql N'CREATE SCHEMA NewSchemaName;';
END

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

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

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

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

ssh -T [email protected]

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

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

I think you need something a bit more generic. Try this:

public static System.Boolean IsNumeric (System.Object Expression)
{
    if(Expression == null || Expression is DateTime)
        return false;

    if(Expression is Int16 || Expression is Int32 || Expression is Int64 || Expression is Decimal || Expression is Single || Expression is Double || Expression is Boolean)
        return true;

    try 
    {
        if(Expression is string)
            Double.Parse(Expression as string);
        else
            Double.Parse(Expression.ToString());
            return true;
        } catch {} // just dismiss errors but return false
        return false;
    }
}

Hope it helps!

I've investigated A LOT on how to properly manage 404s in MVC (specifically MVC3), and this, IMHO is the best solution I've come up with:

In global.asax:

public class MvcApplication : HttpApplication
{
    protected void Application_EndRequest()
    {
        if (Context.Response.StatusCode == 404)
        {
            Response.Clear();

            var rd = new RouteData();
            rd.DataTokens["area"] = "AreaName"; // In case controller is in another area
            rd.Values["controller"] = "Errors";
            rd.Values["action"] = "NotFound";

            IController c = new ErrorsController();
            c.Execute(new RequestContext(new HttpContextWrapper(Context), rd));
        }
    }
}

ErrorsController:

public sealed class ErrorsController : Controller
{
    public ActionResult NotFound()
    {
        ActionResult result;

        object model = Request.Url.PathAndQuery;

        if (!Request.IsAjaxRequest())
            result = View(model);
        else
            result = PartialView("_NotFound", model);

        return result;
    }
}

Edit:

If you're using IoC (e.g. AutoFac), you should create your controller using:

var rc = new RequestContext(new HttpContextWrapper(Context), rd);
var c = ControllerBuilder.Current.GetControllerFactory().CreateController(rc, "Errors");
c.Execute(rc);

Instead of

IController c = new ErrorsController();
c.Execute(new RequestContext(new HttpContextWrapper(Context), rd));

(Optional)

Explanation:

There are 6 scenarios that I can think of where an ASP.NET MVC3 apps can generate 404s.

Generated by ASP.NET:

• Scenario 1: URL does not match a route in the route table.

Generated by ASP.NET MVC:

• Scenario 2: URL matches a route, but specifies a controller that doesn't exist.

• Scenario 3: URL matches a route, but specifies an action that doesn't exist.

Manually generated:

• Scenario 4: An action returns an HttpNotFoundResult by using the method HttpNotFound().

• Scenario 5: An action throws an HttpException with the status code 404.

• Scenario 6: An actions manually modifies the Response.StatusCode property to 404.

Objectives

• (A) Show a custom 404 error page to the user.

• (B) Maintain the 404 status code on the client response (specially important for SEO).

• (C) Send the response directly, without involving a 302 redirection.

Solution Attempt: Custom Errors

<system.web>
    <customErrors mode="On">
        <error statusCode="404" redirect="~/Errors/NotFound"/>
    </customErrors>
</system.web>

Problems with this solution:

• Does not comply with objective (A) in scenarios (1), (4), (6).
• Does not comply with objective (B) automatically. It must be programmed manually.
• Does not comply with objective (C).

Solution Attempt: HTTP Errors

<system.webServer>
    <httpErrors errorMode="Custom">
        <remove statusCode="404"/>
        <error statusCode="404" path="App/Errors/NotFound" responseMode="ExecuteURL"/>
    </httpErrors>
</system.webServer>

Problems with this solution:

• Only works on IIS 7+.
• Does not comply with objective (A) in scenarios (2), (3), (5).
• Does not comply with objective (B) automatically. It must be programmed manually.

Solution Attempt: HTTP Errors with Replace

<system.webServer>
    <httpErrors errorMode="Custom" existingResponse="Replace">
        <remove statusCode="404"/>
        <error statusCode="404" path="App/Errors/NotFound" responseMode="ExecuteURL"/>
    </httpErrors>
</system.webServer>

Problems with this solution:

• Only works on IIS 7+.
• Does not comply with objective (B) automatically. It must be programmed manually.
• It obscures application level http exceptions. E.g. can't use customErrors section, System.Web.Mvc.HandleErrorAttribute, etc. It can't only show generic error pages.

Solution Attempt customErrors and HTTP Errors

<system.web>
    <customErrors mode="On">
        <error statusCode="404" redirect="~/Errors/NotFound"/>
    </customError>
</system.web>

and

<system.webServer>
    <httpErrors errorMode="Custom">
        <remove statusCode="404"/>
        <error statusCode="404" path="App/Errors/NotFound" responseMode="ExecuteURL"/>
    </httpErrors>
</system.webServer>

Problems with this solution:

• Only works on IIS 7+.
• Does not comply with objective (B) automatically. It must be programmed manually.
• Does not comply with objective (C) in scenarios (2), (3), (5).

People that have troubled with this before even tried to create their own libraries (see http://aboutcode.net/2011/02/26/handling-not-found-with-asp-net-mvc3.html). But the previous solution seems to cover all the scenarios without the complexity of using an external library.

Your selector won't select the input field, and if it did it would return a jQuery object. Try this:

$('#test2').is(':checked'); 

After finding this thread, I discovered that my Intellisense only broke after taking a database offline, and any offline database(s) on the instance would kill Intellisense.

In this thread, explaining that in order to restore Intellisense, you must

• take the necessary databases offline, then
• restart the server instance, and finally
• refresh the Intellisense cache.

This procedure has worked for me and Intellisense is now working again.

Yes if the structure is of the same type. Think it as a memory copy.

Open terminal and type "cd < ProjectPath >"

1. Remove existing files: find . -name .DS_Store -print0 | xargs -0 git rm -f --ignore-unmatch

2. nano .gitignore

3. Add this .DS_Store

4. type "ctrl + x"

5. Type "y"

6. Enter to save file

7. git add .gitignore

8. git commit -m '.DS_Store removed.'

Not a barplot solution but using lattice and barchart:

library(lattice)
barchart(Species~Reason,data=Reasonstats,groups=Catergory, 
         scales=list(x=list(rot=90,cex=0.8)))

Make sure return type of you method is same what you want to return. Eg: `

  public int get(int[] r)
  {
     return r[0];
  }

`

Note : return type is int, not int[], so it is able to return int.

In general, prototype can be

public Type get(Type[] array, int index)
{
    return array[index];
}

You can do the following:

  public class Numbers {
    private int number1 = 50;
    private int number2 = 100;
    private List<Integer> list;

    public Numbers() {
      list = new ArrayList<Integer>();
      list.add(number1);
      list.add(number2);
    }

    int getNumber(int pos)
    {
      return list.get(pos);
    }
  }

  public class Test {
    private Numbers numbers;

    public Test(){
      numbers = new Numbers();
      int number1 = numbers.getNumber(0);
      int number2 = numbers.getNumber(1);
    }
  }

If you want to catch the event from the starting of the swipe you can use MotionEvent.ACTION_MOVE and store the first value to compare

private float upX1;
private float upX2;
private float upY1;
private float upY2;
private boolean isTouchCaptured = false;
static final int min_distance = 100;


        viewObject.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                switch (event.getAction()) {
                    case MotionEvent.ACTION_MOVE: {
                        downX = event.getX();
                        downY = event.getY();

                        if (!isTouchCaptured) {
                            upX1 = event.getX();
                            upY1 = event.getY();
                            isTouchCaptured = true;
                        } else {
                            upX2 = event.getX();
                            upY2 = event.getY();

                            float deltaX = upX1 - upX2;
                            float deltaY = upY1 - upY2;
                            //HORIZONTAL SCROLL

I was developing for .NET core 2.1 using log4net 2.0.8 and found NealWalters code moans about 0 arguments for XmlConfigurator.Configure(). I found a solution by Matt Watson here

        log4net.GlobalContext.Properties["LogFileName"] = @"E:\\file1"; //log file path
        var logRepository = LogManager.GetRepository(Assembly.GetEntryAssembly());
        XmlConfigurator.Configure(logRepository, new FileInfo("log4net.config"));

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

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

// this isn't set up for good processing.  
//I don't know what data set has the expiration 
//dates of your accounts.  I assume a list.
// matchfound is a single variablethat returns true if any 1 record is expired.

bool matchFound = false;
            DateTime dateOfExpiration = DateTime.Today.AddDays(-30);
            List<DateTime> accountExpireDates = new List<DateTime>();
            foreach (DateTime date in accountExpireDates)
            {
                if (DateTime.Compare(dateOfExpiration, date) != -1)
                {
                    matchFound = true;
            }
            }

I use eventbug plugin to firebug for this purpose.

The PHP function echo() prints out its input to the web server response.

echo("Hello World!");

prints out Hello World! to the web server response.

echo("<prev>");

prints out the tag to the web server response.

echo do not require valid HTML tags. You can use PHP to print XML, images, excel, HTML and so on.

<prev> is not a HTML tag. Is is a valid XML tag, but since I don't know what page you are working in, i cannot tell you what it is. Maybe it is the root tag of a XML page, or a miswritten <pre> tag.

The correct way to do it for Material design is :

Style :

<style name="MyCheckBox" parent="Theme.AppCompat.Light">  
    <item name="colorControlNormal">@color/foo</item>
    <item name="colorControlActivated">@color/bar</item>
</style>  

Layout :

<CheckBox  
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:checked="true"
    android:text="Check Box"
    android:theme="@style/MyCheckBox"/>

It will preserve Material animations on Lollipop+.

In fact, your query is right except for the typo: your filter is excluding all records: you should change the <= for >= and vice versa:

qry = DBSession.query(User).filter(
        and_(User.birthday <= '1988-01-17', User.birthday >= '1985-01-17'))
# or same:
qry = DBSession.query(User).filter(User.birthday <= '1988-01-17').\
        filter(User.birthday >= '1985-01-17')

Also you can use between:

qry = DBSession.query(User).filter(User.birthday.between('1985-01-17', '1988-01-17'))

You should use CSS to align the textbox. The reason your code above does not work is because by default a div's width is the same as the container it's in, therefore in your example it is pushed below.

The following would work.

<td  colspan="2" class="cell">
                <asp:Label ID="Label6" runat="server" Text="Label"></asp:Label>        
                <asp:TextBox ID="TextBox3" runat="server" CssClass="righttextbox"></asp:TextBox>       
</td>

In your CSS file:

.cell
{
text-align:left;
}

.righttextbox
{
float:right;
}

For Visual Studio 2017 and its new .csproj format

You can no longer just use Install-Package to point to a local file. (That's likely because the PackageReference element doesn't support file paths; it only allows you to specify the package's Id.)

You first have to tell Visual Studio about the location of your package, and then you can add it to a project. What most people do is go into the NuGet Package Manager and add the local folder as a source (menu Tools ? Options ? NuGet Package Manager ? Package Sources). But that means your dependency's location isn't committed (to version-control) with the rest of your codebase.

Local NuGet packages using a relative path

This will add a package source that only applies to a specific solution, and you can use relative paths.

You need to create a nuget.config file in the same directory as your .sln file. Configure the file with the package source(s) you want. When you next open the solution in Visual Studio 2017, any .nupkg files from those source folders will be available. (You'll see the source(s) listed in the Package Manager, and you'll find the packages on the "Browse" tab when you're managing packages for a project.)

Here's an example nuget.config to get you started:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <packageSources>
        <add key="MyLocalSharedSource" value="..\..\..\some\folder" />
    </packageSources>
</configuration>

Backstory

My use case for this functionality is that I have multiple instances of a single code repository on my machine. There's a shared library within the codebase that's published/deployed as a .nupkg file. This approach allows the various dependent solutions throughout our codebase to use the package within the same repository instance. Also, someone with a fresh install of Visual Studio 2017 can just checkout the code wherever they want, and the dependent solutions will successfully restore and build.

1. Go to you package.json

2. Change "react-scripts": "3.x.x" to "react-scripts": "^3.4.0" in the dependencies

3. Reinstall react-scripts: npm I react-scripts

4. Start your project: npm start

Object.assign will only work in single level of object reference.

To do a copy in any depth use as below:

let x = {'a':'a','b':{'c':'c'}};
let y = JSON.parse(JSON.stringify(x));

If want to use any library instead then go with the loadash.js library.

In my case I had all of the proper references in my project. I found that by building the solution the nuget packages were automatically restored.

As discussed in the comments, this can be achieved by converting the entry into Date format and extracting the year, for instance like this:

format(as.Date(df1$Date, format="%d/%m/%Y"),"%Y")

Your module and your class AthleteList have the same name. The line

import AthleteList

imports the module and creates a name AthleteList in your current scope that points to the module object. If you want to access the actual class, use

AthleteList.AthleteList

In particular, in the line

return(AthleteList(templ.pop(0), templ.pop(0), templ))

you are actually accessing the module object and not the class. Try

return(AthleteList.AthleteList(templ.pop(0), templ.pop(0), templ))

Using executeUpdate() on the Query API is faster because it bypasses the persistent context .However , by-passing persistent context would cause the state of instance in the memory and the actual values of that record in the DB are not synchronized.

Consider the following example :

 Employee employee= (Employee)entityManager.find(Employee.class , 1);
 entityManager
     .createQuery("update Employee set name = \'xxxx\' where id=1")
     .executeUpdate();

After flushing, the name in the DB is updated to the new value but the employee instance in the memory still keeps the original value .You have to call entityManager.refresh(employee) to reload the updated name from the DB to the employee instance.It sounds strange if your codes still have to manipulate the employee instance after flushing but you forget to refresh() the employee instance as the employee instance still contains the original values.

Normally , executeUpdate() is used in the bulk update process as it is faster due to bypassing the persistent context

The right way to update an entity is that you just set the properties you want to updated through the setters and let the JPA to generate the update SQL for you during flushing instead of writing it manually.

   Employee employee= (Employee)entityManager.find(Employee.class ,1);
   employee.setName("Updated Name");

Put The GRANT privileges:

GRANT ALL PRIVILEGES ON mydb.* TO 'username'@'%' IDENTIFIED BY 'password';

Let's say you have a typical variadic function you've written. Because at least one argument is required before the variadic one ..., you have to always write an extra argument in usage.

Or do you?

If you wrap your variadic function in a macro, you need no preceding arg. Consider this example:

#define LOGI(...)
    ((void)__android_log_print(ANDROID_LOG_INFO, LOG_TAG, __VA_ARGS__))

This is obviously far more convenient, since you needn't specify the initial argument every time.

Here is my solution for this:

def calc_age_months(from_date, to_date):
    from_date = time.strptime(from_date, "%Y-%m-%d")
    to_date = time.strptime(to_date, "%Y-%m-%d")

    age_in_months = (to_date.tm_year - from_date.tm_year)*12 + (to_date.tm_mon - from_date.tm_mon)

    if to_date.tm_mday < from_date.tm_mday:
        return age_in_months -1
    else
        return age_in_months

This will handle some edge cases as well where the difference in months between 31st Dec 2018 and 1st Jan 2019 will be zero (since the difference is only a day).

std::vector<std::string> split(std::string text, char delim) {
    std::string line;
    std::vector<std::string> vec;
    std::stringstream ss(text);
    while(std::getline(ss, line, delim)) {
        vec.push_back(line);
    }
    return vec;
}

split("String will be split", ' ') -> {"String", "will", "be", "split"}

split("Hello, how are you?", ',') -> {"Hello", "how are you?"}

EDIT: Here's a thing I made, this can use multi-char delimiters, albeit I'm not 100% sure if it always works:

std::vector<std::string> split(std::string text, std::string delim) {
    std::vector<std::string> vec;
    size_t pos = 0, prevPos = 0;
    while (1) {
        pos = text.find(delim, prevPos);
        if (pos == std::string::npos) {
            vec.push_back(text.substr(prevPos));
            return vec;
        }

        vec.push_back(text.substr(prevPos, pos - prevPos));
        prevPos = pos + delim.length();
    }
}

I'd guess that Remove and Substring would tie for first place, since they both slurp up a fixed-size portion of the string, whereas TrimStart does a scan from the left with a test on each character and then has to perform exactly the same work as the other two methods. Seriously, though, this is splitting hairs.

Annoyingly Javascript's date.getSeconds() et al will not pad the result with zeros 11:0:0 instead of 11:00:00.

So I like to use

date.toLocaleTimestring()

Which renders 11:00:00 AM. Just beware when using the extra options, some browsers don't support them (Safari)

Ok I found why the int.ToString() in LINQtoEF fails, please read this post: Problem with converting int to string in Linq to entities

This works on my side :

        List<string> materialTypes = (from u in result.Users
                                      select u.LastName)
                       .Union(from u in result.Users
                               select SqlFunctions.StringConvert((double) u.UserId)).ToList();

On yours it should be like this:

    IList<String> materialTypes = ((from tom in context.MaterialTypes
                                       where tom.IsActive == true
                                       select tom.Name)
                                       .Union(from tom in context.MaterialTypes
                                       where tom.IsActive == true
                                       select SqlFunctions.StringConvert((double)tom.ID))).ToList();

Thanks, i've learnt something today :)

If you want to make use of nested views functionality implemented within ngRoute paradigm, try angular-route-segment - it aims to extend ngRoute rather than to replace it.

using ssh from java should not be as hard as jsch makes it. you might be better off with sshj.

It took me months of googling to find a solution for this issue. You don't need to install a virtual environment running a 32-bit version of Windows to run a program with a 16-bit installer on 64-bit Windows. If the program itself is 32-bit, and just the installer is 16-bit, here's your answer.

There are ways to modify a 16-bit installation program to make it 32-bit so it will install on 64-bit Windows 7. I found the solution on this site:

http://www.reactos.org/forum/viewtopic.php?f=22&t=10988

In my case, the installation program was InstallShield 5.X. The issue was that the setup.exe program used by InstallShield 5.X is 16-bit. First I extracted the installation program contents (changed the extension from .exe to .zip, opened it and extracted). I then replaced the original 16-bit setup.exe, located in the disk1 folder, with InstallShield's 32-bit version of setup.exe (download this file from the site referenced in the above link). Then I just ran the new 32-bit setup.exe in disk1 to start the installation and my program installed and runs perfectly on 64-bit Windows.

You can also repackage this modified installation, so it can be distributed as an installation program, using a free program like Inno Setup 5.

You can use this.setResizable(false); or frameObject.setResizable(false);

This depends a bit from your package system ... if the java command works, you can type readlink -f $(which java) to find the location of the java command. On the OpenSUSE system I'm on now it returns /usr/lib64/jvm/java-1.6.0-openjdk-1.6.0/jre/bin/java (but this is not a system which uses apt-get).

On Ubuntu, it looks like it is in /usr/lib/jvm/java-6-openjdk/ for OpenJDK, and in some other subdirectory of /usr/lib/jvm/ for Suns JDK (and other implementations as well, I think).

Debian is the same.

For any given package you can determine what files it installs and where it installs them by querying dpkg. For example for the package 'openjdk-6-jdk': dpkg -L openjdk-6-jdk

Edit (2020.12.28): GitHub change default master branch to main branch since October 2020. See https://github.com/github/renaming

Update March 2013

Git 1.8.2 added the possibility to track branches.

"git submodule" started learning a new mode to integrate with the tip of the remote branch (as opposed to integrating with the commit recorded in the superproject's gitlink).

# add submodule to track master branch
git submodule add -b master [URL to Git repo];

# update your submodule
git submodule update --remote 

If you had a submodule already present you now wish would track a branch, see "how to make an existing submodule track a branch".

Also see Vogella's tutorial on submodules for general information on submodules.

Note:

git submodule add -b . [URL to Git repo];
                    ^^^

See git submodule man page:

A special value of . is used to indicate that the name of the branch in the submodule should be the same name as the current branch in the current repository.

See commit b928922727d6691a3bdc28160f93f25712c565f6:

submodule add: If --branch is given, record it in .gitmodules

This allows you to easily record a submodule.<name>.branch option in .gitmodules when you add a new submodule. With this patch,

$ git submodule add -b <branch> <repository> [<path>]
$ git config -f .gitmodules submodule.<path>.branch <branch>

reduces to

$ git submodule add -b <branch> <repository> [<path>]

This means that future calls to

$ git submodule update --remote ...

will get updates from the same branch that you used to initialize the submodule, which is usually what you want.

Original answer (February 2012):

A submodule is a single commit referenced by a parent repo.
Since it is a Git repo on its own, the "history of all commits" is accessible through a git log within that submodule.

So for a parent to track automatically the latest commit of a given branch of a submodule, it would need to:

• cd in the submodule
• git fetch/pull to make sure it has the latest commits on the right branch
• cd back in the parent repo
• add and commit in order to record the new commit of the submodule.

gitslave (that you already looked at) seems to be the best fit, including for the commit operation.

It is a little annoying to make changes to the submodule due to the requirement to check out onto the correct submodule branch, make the change, commit, and then go into the superproject and commit the commit (or at least record the new location of the submodule).

Other alternatives are detailed here.

It's fairly easy using the New-SelfSignedCertificate command in Powershell. Open powershell and run these 3 commands.

1) Create certificate:
$cert = New-SelfSignedCertificate -DnsName www.yourwebsite.com -Type CodeSigning -CertStoreLocation Cert:\CurrentUser\My

2) set the password for it:
$CertPassword = ConvertTo-SecureString -String "my_passowrd" -Force –AsPlainText

3) Export it:
Export-PfxCertificate -Cert "cert:\CurrentUser\My\$($cert.Thumbprint)" -FilePath "d:\selfsigncert.pfx" -Password $CertPassword

Your certificate selfsigncert.pfx will be located @ D:/

Optional step: You would also require to add certificate password to system environment variables. do so by entering below in cmd: setx CSC_KEY_PASSWORD "my_password"

For Swift 5

Remove Cell

    let indexPath = [NSIndexPath(row: yourArray-1, section: 0)]
    yourArray.remove(at: buttonTag)
    self.tableView.beginUpdates()

    self.tableView.deleteRows(at: indexPath as [IndexPath] , with: .fade)
    self.tableView.endUpdates()
    self.tableView.reloadData()// Not mendatory, But In my case its requires

Add new cell

    yourArray.append(4)

    tableView.insertRows(at: [
        (NSIndexPath(row: yourArray.count-1, section: 0) as IndexPath)], with: .automatic)
    tableView.endUpdates()

I had the same issue. When I checked my config file I noticed that 'fetch = +refs/heads/:refs/remotes/origin/' was on the same line as 'url = Z:/GIT/REPOS/SEL.git' as shown:

[core]
    repositoryformatversion = 0
    filemode = false
    bare = false
    logallrefupdates = true
    symlinks = false
    ignorecase = true
[remote "origin"]
    url = Z:/GIT/REPOS/SEL.git     fetch = +refs/heads/*:refs/remotes/origin/*
[branch "master"]
    remote = origin
    merge = refs/heads/master
[gui]
    wmstate = normal
    geometry = 1109x563+32+32 216 255

At first I did not think that this would have mattered but after seeing the post by Magere I moved the line and that fixed the problem:

[core]
    repositoryformatversion = 0
    filemode = false
    bare = false
    logallrefupdates = true
    symlinks = false
    ignorecase = true
[remote "origin"]
    url = Z:/GIT/REPOS/SEL.git
    fetch = +refs/heads/*:refs/remotes/origin/*
[branch "master"]
    remote = origin
    merge = refs/heads/master
[gui]
    wmstate = normal
    geometry = 1109x563+32+32 216 255

In C++ you can do:

// Declaration and assign variable a
int a = 7;
// Declaration pointer b
int* b;
// Assign address of variable a to pointer b
b = &a;

// Declaration pointer c
int** c;
// Assign address of pointer b to pointer c
c = &b;

std::cout << "a: " << a << "\n";       // Print value of variable a
std::cout << "&a: " << &a << "\n";     // Print address of variable a

std::cout << "" << "" << "\n";

std::cout << "b: " << b << "\n";       // Print address of variable a
std::cout << "*b: " << *b << "\n";     // Print value of variable a
std::cout << "&b: " << &b << "\n";     // Print address of pointer b

std::cout << "" << "" << "\n";

std::cout << "c: " << c << "\n";       // Print address of pointer b
std::cout << "**c: " << **c << "\n";   // Print value of variable a
std::cout << "*c: " << *c << "\n";     // Print address of variable a
std::cout << "&c: " << &c << "\n";     // Print address of pointer c

def get_pair(line):
    key, sep, value = line.strip().partition(" ")
    return int(key), value

with open("file.txt") as fd:    
    d = dict(get_pair(line) for line in fd)

There's no way to initiate a file transfer back to/from local Windows from a SSH session opened in PuTTY window.

Though PuTTY supports connection-sharing.

While you still need to run a compatible file transfer client (pscp or psftp), no new login is required, it automatically (if enabled) makes use of an existing PuTTY session.

To enable the sharing see:
Sharing an SSH connection between PuTTY tools.

Even without connection-sharing, you can still use the psftp or pscp from Windows command line.

See How to use PSCP to copy file from Unix machine to Windows machine ...?

Note that the scp is OpenSSH program. It's primarily *nix program, but you can run it via Windows Subsystem for Linux or get a Windows build from Win32-OpenSSH (it is already built-in in the latest versions of Windows 10).

If you really want to download the files to a local desktop, you have to specify a target path as %USERPROFILE%\Desktop (what typically resolves to a path like C:\Users\username\Desktop).

Alternative way is to use WinSCP, a GUI SFTP/SCP client. While you browse the remote site, you can anytime open SSH terminal to the same site using Open in PuTTY command.
See Opening Session in PuTTY.

With an additional setup, you can even make PuTTY automatically navigate to the same directory you are browsing with WinSCP.
See Opening PuTTY in the same directory.

(I'm the author of WinSCP)

There is one thing that many people don't realize right away when dealing with loops and invariants. They get confused between the loop invariant, and the loop conditional ( the condition which controls termination of the loop ).

As people point out, the loop invariant must be true

1. before the loop starts
2. before each iteration of the loop
3. after the loop terminates

( although it can temporarily be false during the body of the loop ). On the other hand the loop conditional must be false after the loop terminates, otherwise the loop would never terminate.

Thus the loop invariant and the loop conditional must be different conditions.

A good example of a complex loop invariant is for binary search.

bsearch(type A[], type a) {
start = 1, end = length(A)

    while ( start <= end ) {
        mid = floor(start + end / 2)

        if ( A[mid] == a ) return mid
        if ( A[mid] > a ) end = mid - 1
        if ( A[mid] < a ) start = mid + 1

    }
    return -1

}

So the loop conditional seems pretty straight forward - when start > end the loop terminates. But why is the loop correct? What is the loop invariant which proves it's correctness?

The invariant is the logical statement:

if ( A[mid] == a ) then ( start <= mid <= end )

This statement is a logical tautology - it is always true in the context of the specific loop / algorithm we are trying to prove. And it provides useful information about the correctness of the loop after it terminates.

If we return because we found the element in the array then the statement is clearly true, since if A[mid] == a then a is in the array and mid must be between start and end. And if the loop terminates because start > end then there can be no number such that start <= mid and mid <= end and therefore we know that the statement A[mid] == a must be false. However, as a result the overall logical statement is still true in the null sense. ( In logic the statement if ( false ) then ( something ) is always true. )

Now what about what I said about the loop conditional necessarily being false when the loop terminates? It looks like when the element is found in the array then the loop conditional is true when the loop terminates!? It's actually not, because the implied loop conditional is really while ( A[mid] != a && start <= end ) but we shorten the actual test since the first part is implied. This conditional is clearly false after the loop regardless of how the loop terminates.

I am using @ComponentScan as follows for the same use case. This is the same as BenSchro10's XML answer but this uses annotations. Both use a filter with type=AspectJ

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
import org.springframework.boot.autoconfigure.jersey.JerseyAutoConfiguration;
import org.springframework.boot.autoconfigure.jms.JmsAutoConfiguration;
import org.springframework.boot.autoconfigure.jmx.JmxAutoConfiguration;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.FilterType;
import org.springframework.context.annotation.ImportResource;

@SpringBootApplication
@EnableAutoConfiguration
@ComponentScan(basePackages = { "com.example" },
    excludeFilters = @ComponentScan.Filter(type = FilterType.ASPECTJ, pattern = "com.example.ignore.*"))
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

As Yaron mentioned, there isn't any difference between where and filter.

filter is an overloaded method that takes a column or string argument. The performance is the same, regardless of the syntax you use.

We can use explain() to see that all the different filtering syntaxes generate the same Physical Plan. Suppose you have a dataset with person_name and person_country columns. All of the following code snippets will return the same Physical Plan below:

df.where("person_country = 'Cuba'").explain()
df.where($"person_country" === "Cuba").explain()
df.where('person_country === "Cuba").explain()
df.filter("person_country = 'Cuba'").explain()

These all return this Physical Plan:

== Physical Plan ==
*(1) Project [person_name#152, person_country#153]
+- *(1) Filter (isnotnull(person_country#153) && (person_country#153 = Cuba))
   +- *(1) FileScan csv [person_name#152,person_country#153] Batched: false, Format: CSV, Location: InMemoryFileIndex[file:/Users/matthewpowers/Documents/code/my_apps/mungingdata/spark2/src/test/re..., PartitionFilters: [], PushedFilters: [IsNotNull(person_country), EqualTo(person_country,Cuba)], ReadSchema: struct<person_name:string,person_country:string>

The syntax doesn't change how filters are executed under the hood, but the file format / database that a query is executed on does. Spark will execute the same query differently on Postgres (predicate pushdown filtering is supported), Parquet (column pruning), and CSV files. See here for more details.

assuming you want to find a value in a numpy array, I guess something like this might work:

Numpy.where(arr=="value")[0]

      <div class="overflow-auto p-3 mb-3 mb-md-0 mr-md-3 bg-light" style="max-width: 260px; max-height: 100px;">
        <strong>Column 0 </strong><br>
        <strong>Column 1</strong><br>
        <strong>Column 2</strong><br>
        <strong>Column 3</strong><br>
        <strong>Column 4</strong><br>
        <strong>Column 5</strong><br>
        <strong>Column 6</strong><br>
        <strong>Column 7</strong><br>
        <strong>Column 8</strong><br>
        <strong>Column 9</strong><br>
        <strong>Column 10</strong><br>
        <strong>Column 11</strong><br>
        <strong>Column 12</strong><br>
        <strong>Column 13</strong><br>
      </div>
    </div>

let dict : [String : Any] = ["FirstName" : "Maninder" , "LastName" : "Singh" , "Address" : "Chandigarh"]
dict.forEach { print($0) }

Result would be

("FirstName", "Maninder") ("LastName", "Singh") ("Address", "Chandigarh")

you can check like this

declare @vchar varchar(50)
set @vchar ='34343';
select case when @vchar not like '%[^0-9]%' then 'Number' else 'Not a Number' end

Checking palindrome for first half of the string with the rest, this case assumes removal of any white spaces.

public int isPalindrome(String a) {
        //Remove all spaces and non alpha characters
        String ab = a.replaceAll("[^A-Za-z0-9]", "").toLowerCase();
        //System.out.println(ab);

        for (int i=0; i<ab.length()/2; i++) {
            if(ab.charAt(i) != ab.charAt((ab.length()-1)-i)) {
                return 0;
            }
        }   
        return 1;
    }

Its better to always encode spaces as %20, not as "+".

It was RFC-1866 (HTML 2.0 specification), which specified that space characters should be encoded as "+" in "application/x-www-form-urlencoded" content-type key-value pairs. (see paragraph 8.2.1. subparagraph 1.). This way of encoding form data is also given in later HTML specifications, look for relevant paragraphs about application/x-www-form-urlencoded.

Here is an example of such a string in URL where RFC-1866 allows encoding spaces as pluses: "http://example.com/over/there?name=foo+bar". So, only after "?", spaces can be replaced by pluses, according to RFC-1866. In other cases, spaces should be encoded to %20. But since it's hard to determine the context, it's the best practice to never encode spaces as "+".

I would recommend to percent-encode all character except "unreserved" defined in RFC-3986, p.2.3

unreserved = ALPHA / DIGIT / "-" / "." / "_" / "~"

The script below is a generic solution that works for me. It is based on ideas pulled from this and other threads.

When a link with an href attribute beginning with "#" is clicked, it scrolls the page smoothly to the indicated div. Where only the "#" is present, it scrolls smoothly to the top of the page.

$('a[href^=#]').click(function(){
    event.preventDefault();
    var target = $(this).attr('href');
    if (target == '#')
      $('html, body').animate({scrollTop : 0}, 600);
    else
      $('html, body').animate({
        scrollTop: $(target).offset().top - 100
    }, 600);
});

For example, When the code above is present, clicking a link with the tag <a href="#"> scrolls to the top of the page at speed 600. Clicking a link with the tag <a href="#mydiv"> scrolls to 100px above <div id="mydiv"> at speed 600. Feel free to change these numbers.

I hope it helps!

There is a ProcessHelper Class in PublicDomain open source code which might interest you.

Below should work.

SimpleDateFormat df = new SimpleDateFormat("dd-MMM-yyyy");
Date oldDate = df.parse(df.format(date)); //this date is your old date object

Try this:

XmlDocument doc = new XmlDocument();
doc.Load(@"C:\Path\To\Xml\File.xml");

Or alternatively if you have the XML in a string use the LoadXml method.

Once you have it loaded, you can use SelectNodes and SelectSingleNode to query specific values, for example:

XmlNode node = doc.SelectSingleNode("//Company/Email/text()");
// node.Value contains "[email protected]"

Finally, note that your XML is invalid as it doesn't contain a single root node. It must be something like this:

<Data>
    <Employee>
        <Name>Test</Name>
        <ID>123</ID>
    </Employee>
    <Company>
        <Name>ABC</Name>
        <Email>[email protected]</Email>
    </Company>
</Data>
