Programs & Examples On #Canexecute

This exception message doesn't mean it requires a primary key to be defined in your database, it means it requires a primary key to be defined in your class.

Although you've attempted to do so:

private Guid _id;
[Key]
public Guid ID
{
    get { return _id; }
}

This has no effect, as Entity Framework ignores read-only properties. It has to: when it retrieves a Fruits record from the database, it constructs a Fruit object, and then calls the property setters for each mapped property. That's never going to work for read-only properties.

You need Entity Framework to be able to set the value of ID. This means the property needs to have a setter.

I've just created a little example showing how to implement commands in convention over configuration style. However it requires Reflection.Emit() to be available. The supporting code may seem a little weird but once written it can be used many times.

Teaser:

public class SampleViewModel: BaseViewModelStub
{
    public string Name { get; set; }

    [UiCommand]
    public void HelloWorld()
    {
        MessageBox.Show("Hello World!");
    }

    [UiCommand]
    public void Print()
    {
        MessageBox.Show(String.Concat("Hello, ", Name, "!"), "SampleViewModel");
    }

    public bool CanPrint()
    {
        return !String.IsNullOrEmpty(Name);
    }
}

}

UPDATE: now there seem to exist some libraries like http://www.codeproject.com/Articles/101881/Executing-Command-Logic-in-a-View-Model that solve the problem of ICommand boilerplate code.

If you are working in Eclipse IDE, that could mean that you haven't close the file in the previous launch of the application. When I had the same error message at trying to delete a file, that was the reason. It seems, Eclipse IDE doesn't close all files after termination of an application.

As another poster said, it's typically preferable to have interfaces define capabilities not types. I would tend not to "implement" something like a "User," and this is why "IUser" often isn't really necessary in the way described here. I often see classes as nouns and interfaces as adjectives:

class Number implements Comparable{...}  
class MyThread implements Runnable{...}
class SessionData implements Serializable{....}

Sometimes an Adjective doesn't make sense, but I'd still generally be using interfaces to model behavior, actions, capabilities, properties, etc,... not types.

Also, If you were really only going to make one User and call it User then what's the point of also having an IUser interface? And if you are going to have a few different types of users that need to implement a common interface, what does appending an "I" to the interface save you in choosing names of the implementations?

I think a more realistic example would be that some types of users need to be able to login to a particular API. We could define a Login interface, and then have a "User" parent class with SuperUser, DefaultUser, AdminUser, AdministrativeContact, etc suclasses, some of which will or won't implement the Login (Loginable?) interface as necessary.

There's no direct way to do it yet, unfortunately, but there are a couple indirect ways:

[dt.year for dt in dates.astype(object)]

or

[datetime.datetime.strptime(repr(d), "%Y-%m-%d %H:%M:%S").year for d in dates]

both inspired by the examples here.

Both of these work for me on Numpy 1.6.1. You may need to be a bit more careful with the second one, since the repr() for the datetime64 might have a fraction part after a decimal point.

Use the "REPLACE" string function on the column in question:

UPDATE (yourTable)
SET YourColumn = REPLACE(YourColumn, '*', '')
WHERE (your conditions)

Replace the "*" with the character you want to strip out and specify your WHERE clause to match the rows you want to apply the update to.

Of course, the REPLACE function can also be used - as other answerer have shown - in a SELECT statement - from your question, I assumed you were trying to update a table.

If you want the query to return a 0 instead of a string of zeroes or any other value for that matter you can turn this into a case statement like this:

select CASE
      WHEN ColumnName = substring(ColumnName, patindex('%[^0]%',ColumnName), 10) 
       THEN '0'
      ELSE substring(ColumnName, patindex('%[^0]%',ColumnName), 10) 
      END

I think if you just bubble an exception, it should be handled in the jQuery callback that is passed in for the 'error' option. (We also log this exception on the server side to a central log). No special HTTP error code required, but I'm curious to see what other folks do, too.

This is what I do, but that's just my $.02

If you are going to be RESTful and return error codes, try to stick to the standard codes set forth by the W3C: http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html

As other people said defining private methods in the @implementation block is OK for most purposes.

On the topic of code organization - I like to keep them together under pragma mark private for easier navigation in Xcode

@implementation MyClass 
// .. public methods

# pragma mark private 
// ...

@end

Yes. It will work: FileInfo.CopyTo Method

Use this method to allow or prevent overwriting of an existing file. Use the CopyTo method to prevent overwriting of an existing file by default.

All other responses are correct, but since you asked for FileInfo, here's a sample:

FileInfo fi = new FileInfo(@"c:\yourfile.ext");
fi.CopyTo(@"d:\anotherfile.ext", true); // existing file will be overwritten

There is a possibility to find the PHP version of other domain by checking "X-Powered-By" response header in the browser through developer tools as other already mentioned it. If it is not exposed through the php.ini configuration there is no way you can get it unless you have access to the server.

 @Override
    protected void onPostExecute(final Boolean success) {
        mProgressDialog.dismiss();
        mProgressDialog = null;

setting the value null works for me

This is how I do. I have added explanation to understand what the heck is going on.

Initialize Local Repository

• first initialize Git with

  git init

• Add all Files for version control with

  git add .

• Create a commit with message of your choice

  git commit -m 'AddingBaseCode'

Initialize Remote Repository

• Create a project on GitHub and copy the URL of your project . as shown below:

  

Link Remote repo with Local repo

• Now use copied URL to link your local repo with remote GitHub repo. When you clone a repository with git clone, it automatically creates a remote connection called origin pointing back to the cloned repository. The command remote is used to manage set of tracked repositories.

  git remote add origin https://github.com/hiteshsahu/Hassium-Word.git

Synchronize

• Now we need to merge local code with remote code. This step is critical otherwise we won't be able to push code on GitHub. You must call 'git pull' before pushing your code.

  git pull origin master --allow-unrelated-histories

Commit your code

• Finally push all changes on GitHub

  git push -u origin master

dateadd(month,1+datediff(month,0,getdate()),-1)

To check run:

print dateadd(month,1+datediff(month,0,@date),-1)

before you send the email you can press <ESC> f (Escape followed by f) to change the From: Address.

Constraint: This only works if you use mutt in curses mode and do not wan't to script it or if you want to change the address permanent. Then the other solutions are way better!

The XmlTextWriter is usually used for generating (not updating) XML content. When you load the xml file into an XmlDocument, you don't need a separate writer.

Just update the node you have selected and .Save() that XmlDocument.

Try this command:

pip3 install --upgrade setuptools pip

You could do:

try:
    do_stuff()
except Exception, err:
    print(Exception, err)
    raise err

There are two syntax errors in your ternary conditional:

1. remove the keyword if. Check the correct syntax here.

2. You are missing a parenthesis in your code. If you format it like this:

   {(this.props.schema.collectionName.length < 0 ? 
      (<Expandable></Expandable>) 
      : (<h1>hejsan</h1>) 
   )}
   

Hope this works!

Most common way:

console.log(object);

However I must mention JSON.stringify which is useful to dump variables in non-browser scripts:

console.log( JSON.stringify(object) );

The JSON.stringify function also supports built-in prettification as pointed out by Simon Zyx.

Example:

var obj = {x: 1, y: 2, z: 3};

console.log( JSON.stringify(obj, null, 2) ); // spacing level = 2

The above snippet will print:

{
  "x": 1,
  "y": 2,
  "z": 3
}

On caniuse.com you can view the browsers that support natively the JSON.stringify function: http://caniuse.com/json

You can also use the Douglas Crockford library to add JSON.stringify support on old browsers: https://github.com/douglascrockford/JSON-js

Docs for JSON.stringify: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify

I hope this helps :-)

imperative and declarative describe two opposing styles of programming. imperative is the traditional "step by step recipe" approach while declarative is more "this is what i want, now you work out how to do it".

these two approaches occur throughout programming - even with the same language and the same program. generally the declarative approach is considered preferable, because it frees the programmer from having to specify so many details, while also having less chance for bugs (if you describe the result you want, and some well-tested automatic process can work backwards from that to define the steps then you might hope that things are more reliable than having to specify each step by hand).

on the other hand, an imperative approach gives you more low level control - it's the "micromanager approach" to programming. and that can allow the programmer to exploit knowledge about the problem to give a more efficient answer. so it's not unusual for some parts of a program to be written in a more declarative style, but for the speed-critical parts to be more imperative.

as you might imagine, the language you use to write a program affects how declarative you can be - a language that has built-in "smarts" for working out what to do given a description of the result is going to allow a much more declarative approach than one where the programmer needs to first add that kind of intelligence with imperative code before being able to build a more declarative layer on top. so, for example, a language like prolog is considered very declarative because it has, built-in, a process that searches for answers.

so far, you'll notice that i haven't mentioned functional programming. that's because it's a term whose meaning isn't immediately related to the other two. at its most simple, functional programming means that you use functions. in particular, that you use a language that supports functions as "first class values" - that means that not only can you write functions, but you can write functions that write functions (that write functions that...), and pass functions to functions. in short - that functions are as flexible and common as things like strings and numbers.

it might seem odd, then, that functional, imperative and declarative are often mentioned together. the reason for this is a consequence of taking the idea of functional programming "to the extreme". a function, in it's purest sense, is something from maths - a kind of "black box" that takes some input and always gives the same output. and that kind of behaviour doesn't require storing changing variables. so if you design a programming language whose aim is to implement a very pure, mathematically influenced idea of functional programming, you end up rejecting, largely, the idea of values that can change (in a certain, limited, technical sense).

and if you do that - if you limit how variables can change - then almost by accident you end up forcing the programmer to write programs that are more declarative, because a large part of imperative programming is describing how variables change, and you can no longer do that! so it turns out that functional programming - particularly, programming in a functional language - tends to give more declarative code.

to summarise, then:

• imperative and declarative are two opposing styles of programming (the same names are used for programming languages that encourage those styles)

• functional programming is a style of programming where functions become very important and, as a consequence, changing values become less important. the limited ability to specify changes in values forces a more declarative style.

so "functional programming" is often described as "declarative".

You can change

Range("B3:B65536").Copy Destination:=Sheets("DB").Range("B" & lastrow)

to

Range("B3:B65536").Copy 
Sheets("DB").Range("B" & lastrow).PasteSpecial xlPasteValues

BTW, if you have xls file (excel 2003), you would get an error if your lastrow would be greater 3.

Try to use this code instead:

Sub Get_Data()
    Dim lastrowDB As Long, lastrow As Long
    Dim arr1, arr2, i As Integer

    With Sheets("DB")
        lastrowDB = .Cells(.Rows.Count, "A").End(xlUp).Row + 1
    End With

    arr1 = Array("B", "C", "D", "E", "F", "AH", "AI", "AJ", "J", "P", "AF")
    arr2 = Array("B", "A", "C", "P", "D", "E", "G", "F", "H", "I", "J")

    For i = LBound(arr1) To UBound(arr1)
        With Sheets("Sheet1")
             lastrow = Application.Max(3, .Cells(.Rows.Count, arr1(i)).End(xlUp).Row)
             .Range(.Cells(3, arr1(i)), .Cells(lastrow, arr1(i))).Copy
             Sheets("DB").Range(arr2(i) & lastrowDB).PasteSpecial xlPasteValues
        End With
    Next
    Application.CutCopyMode = False
End Sub

Note, above code determines last non empty row on DB sheet in column A (variable lastrowDB). If you need to find lastrow for each destination column in DB sheet, use next modification:

For i = LBound(arr1) To UBound(arr1)
   With Sheets("DB")
       lastrowDB = .Cells(.Rows.Count, arr2(i)).End(xlUp).Row + 1
   End With

   ' NEXT CODE

Next

You could also use next approach instead Copy/PasteSpecial. Replace

.Range(.Cells(3, arr1(i)), .Cells(lastrow, arr1(i))).Copy
Sheets("DB").Range(arr2(i) & lastrowDB).PasteSpecial xlPasteValues

with

Sheets("DB").Range(arr2(i) & lastrowDB).Resize(lastrow - 2).Value = _
      .Range(.Cells(3, arr1(i)), .Cells(lastrow, arr1(i))).Value

Blow codes could help you...

Fetch Numbers:

return string.Concat(input.Where(char.IsNumber));

Fetch Letters:

return string.Concat(input.Where(char.IsLetter));

int i = 0;
int count = 1;
        while ('e'!= list[i] ) {
            i++;
            count++;
        }

        System.out.println(count);

Heres a few methods that convert an array of bytes to a string. I've tested them they work well.

public String getStringFromByteArray(byte[] settingsData) {

    ByteArrayInputStream byteArrayInputStream = new ByteArrayInputStream(settingsData);
    Reader reader = new BufferedReader(new InputStreamReader(byteArrayInputStream));
    StringBuilder sb = new StringBuilder();
    int byteChar;

    try {
        while((byteChar = reader.read()) != -1) {
            sb.append((char) byteChar);
        }
    }
    catch(IOException e) {
        e.printStackTrace();
    }

    return sb.toString();

}

public String getStringFromByteArray(byte[] settingsData) {

    StringBuilder sb = new StringBuilder();
    for(byte willBeChar: settingsData) {
        sb.append((char) willBeChar);
    }

    return sb.toString();

}

The following code allows you to specify the row/column number and get the resulting cell value:

WebDriver driver = new ChromeDriver();
WebElement base = driver.findElement(By.className("Table"));
tableRows = base.findElements(By.tagName("tr"));
List<WebElement> tableCols = tableRows.get([ROW_NUM]).findElements(By.tagName("td"));
String cellValue = tableCols.get([COL_NUM]).getText();

It seems that many of the ideas listed still use ordering

However, if you use a temporary table, you are able to assign a random index (like many of the solutions have suggested), and then grab the first one that is greater than an arbitrary number between 0 and 1.

For example (for DB2):

WITH TEMP AS (
SELECT COMLUMN, RAND() AS IDX FROM TABLE)
SELECT COLUMN FROM TABLE WHERE IDX > .5
FETCH FIRST 1 ROW ONLY

I've added

public void ExportToFile(string path, DataTable tabela)
{

     DataColumnCollection colunas = tabela.Columns;

     foreach (DataRow linha in tabela.Rows)
     {

           this.AddRow();

           foreach (DataColumn coluna in colunas)

           {

               this[coluna.ColumnName] = linha[coluna];

           }

      }
      this.ExportToFile(path);

}

Previous code does not work with old .NET versions. For 3.5 version of framework use this other version:

        public void ExportToFile(string path)
    {
        bool abort = false;
        bool exists = false;
        do
        {
            exists = File.Exists(path);
            if (!exists)
            {
                if( !Convert.ToBoolean( File.CreateText(path) ) )
                        abort = true;
            }
        } while (!exists || abort);

        if (!abort)
        {
            //File.OpenWrite(path);
            using (StreamWriter w = File.AppendText(path))
            {
                w.WriteLine("hello");
            }

        }

        //File.WriteAllText(path, Export());
    }

Implement in this way

String i="hi";
Intent i = new Intent(this, ActivityTwo.class);
//Create the bundle
Bundle b = new Bundle();
//Add your data to bundle
b.putString(“stuff”, i);
i.putExtras(b);
startActivity(i);

Begin that second activity, inside this class to utilize the Bundle values use this code

Bundle bundle = getIntent().getExtras();
String text= bundle.getString("stuff");

Gantt chart is wrong... First process P3 has arrived so it will execute first. Since the burst time of P3 is 3sec after the completion of P3, processes P2,P4, and P5 has been arrived. Among P2,P4, and P5 the shortest burst time is 1sec for P2, so P2 will execute next. Then P4 and P5. At last P1 will be executed.

Gantt chart for this ques will be:

| P3 | P2 | P4 | P5 | P1 |

1    4    5    7   11   14

Average waiting time=(0+2+2+3+3)/5=2

Average Turnaround time=(3+3+4+7+6)/5=4.6

Technically you shouldn't have to, that's the point of generics, so you can do compile-type checking:

public int indexOf(E arg0) {
   ...
}

but then the @Override may be a problem if you have a class hierarchy. Otherwise see Yishai's answer.

I have a better way:

http
    .authorizeRequests()
    .antMatchers("/api/v1/signup/**").permitAll()
    .anyRequest().authenticated()

You can add functionality to an Array by extending its prototype object.

Array.prototype.nullify = function( n ) {
    n = n >>> 0;
    for( var i = 0; i < n; ++i ) {
        this[ i ] = null;
    }
    return this;
};

Then:

var arr = [].nullify(9);

or:

var arr = [].nullify(9).map(function() { return [].nullify(9); });

I wonder why the best answer that I've found is only in the comments! (by Daenyth with 86 up votes)

git reset --hard origin

This command will sync the local repository with the remote repository getting rid of every change you have made on your local. You can also do the following to fetch the exact branch that you have in the origin.

git reset --hard origin/<branch>

If you're only getting these to manually pass into df.set_index(), that's unnecessary. Just directly do df.set_index['your_col_name', drop=False], already.

It's very rare in pandas that you need to get an index as a Python list (unless you're doing something pretty funky, or else passing them back to NumPy), so if you're doing this a lot, it's a code smell that you're doing something wrong.

Using cyclic generator:

import string
from itertools import cycle


def caesarCipherEncryptor(s, key):
    def generate_letters():
        yield from cycle(string.ascii_lowercase)
    
    def find_next(v, g, c):
        # Eat up characters until we arrive at the plaintext character
        while True:
            if v == next(g):
                break
        
        # Increment the plaintext character by the count using the generator
        try:
            for _ in range(c):
                item = next(g)
            return item
        except UnboundLocalError:
            return v

    return "".join([find_next(i, generate_letters(), key) for i in s])

# Outputs
>>> caesarCipherEncryptor("xyz", 3)
>>> 'abc'

You need to use ContextCompat.getColor(), which is part of the Support V4 Library (so it will work for all the previous API).

ContextCompat.getColor(context, R.color.my_color)

As specified in the documentation, "Starting in M, the returned color will be styled for the specified Context's theme". SO no need to worry about it.

You can add the Support V4 library by adding the following to the dependencies array inside your app build.gradle:

compile 'com.android.support:support-v4:23.0.1'

npm install --save bootstrap

afterwards, inside angular.json (previously .angular-cli.json) inside the project's root folder, find styles and add the bootstrap css file like this:

for angular 6

"styles": [
          "../node_modules/bootstrap/dist/css/bootstrap.min.css",
          "styles.css"
],

for angular 7

"styles": [
          "node_modules/bootstrap/dist/css/bootstrap.min.css",
          "src/styles.css"
],

If you are on adb over network, try to connect via USB instead or vice versa. This did the trick for me. After accepting it once it always works later on.

In the Heroku documentation; Getting started whit rails 4, they say:

You will also need to remove the username field in your database.yml if there is one so: In file config/database.yml remove: username: myapp

Then you just delete that line in "development:", if you don't pg tells to the database that works under role "myapp"

This line tells rails that the database myapp_development should be run under a role of myapp. Since you likely don’t have this role in your database we will remove it. With the line remove Rails will try to access the database as user who is currently logged into the computer.

Also remember to create the database for development:

$createdb myapp_development

Repleace "myapp" for your app name

Transport level errors are often linked to the connection to sql server being broken ... usually network.

Timeout Expired is usually thrown when a sql query takes too long to run.

So few options can be :

1. Check for the connection in VPN (if used) or any other tool
2. Restart IIS
3. Restart machine
4. Optimize sql queries.

Since anonymous classes extend the given class you can store them in a variable.

eg.

Thread t = new Thread()
{
    public void run() {
        System.out.println("blah");
    }
};
t.start();

Alternatively, you can just call the start method on the object you have immediately created.

new Thread()
{
    public void run() {
        System.out.println("blah");
    }
}.start();
// similar to new Thread().start();

Though personally, I would always advise creating an anonymous instance of Runnable rather than Thread as the compiler will warn you if you accidentally get the method signature wrong (for an anonymous class it will warn you anyway I think, as anonymous classes can't define new non-private methods).

eg

new Thread(new Runnable()
{
    @Override
    public void run() {
        System.out.println("blah");
    }
}).start();

Daemon threads are killed ungracefully so any finalizer instructions are not executed. A possible solution is to check is main thread is alive instead of infinite loop.

E.g. for Python 3:

while threading.main_thread().isAlive():
    do.you.subthread.thing()
gracefully.close.the.thread()

See Check if the Main Thread is still alive from another thread.

I'm posting an answer from another thread because it's what worked well for me, the trick is to add support for both architectures :

Posting this because I could not find a direct answer and had to look at a couple of different posts to get what I wanted done...

I was able to use the x86 Accelerated (HAXM) emulator by simply adding this to my Module's build.gradle script Inside android{} block:

splits {
        abi {
            enable true
            reset()
            include 'x86', 'armeabi-v7a'
            universalApk true
        }
    }

Run (build)... Now there will be a (yourapp)-x86-debug.apk in your output folder. I'm sure there's a way to automate installing upon Run but I just start my preferred HAXM emulator and use command line:

adb install (yourapp)-x86-debug.apk

You need to convert the coordinates to radians to do the spherical geometry. Once converted, then you can calculate a distance between the two points. The distance then can be converted to any measure you want.

for /f "tokens=* delims= " %%f in (myfile) do

This reads a file line-by-line, removing leading spaces (thanks, jeb).

set line=%%f

sets then the line variable to the line just read and

call :procesToken

calls a subroutine that does something with the line

:processToken

is the start of the subroutine mentioned above.

for /f "tokens=1* delims=/" %%a in ("%line%") do

will then split the line at /, but stopping tokenization after the first token.

echo Got one token: %%a

will output that first token and

set line=%%b

will set the line variable to the rest of the line.

if not "%line%" == "" goto :processToken

And if line isn't yet empty (i.e. all tokens processed), it returns to the start, continuing with the rest of the line.

You are also able to do some text manipulation inside the braces:

STRING="./folder/subfolder/file.txt"
echo ${STRING} ${STRING%/*/*}

Result:

./folder/subfolder/file.txt ./folder

or

STRING="This is a string"
echo ${STRING// /_}

Result:

This_is_a_string

You are right in "regular variables" are not needed... But it is more helpful for the debugging and to read a script.

A non-bare repository simply has a checked-out working tree. The working tree does not store any information about the state of the repository (branches, tags, etc.); rather, the working tree is just a representation of the actual files in the repo, which allows you to work on (edit, etc.) the files.

I use inf/-inf as initial values to find minimum/maximum value of a measurement. Lets say that you measure temperature with a sensor and you want to keep track of minimum/maximum temperature. The sensor might provide a valid temperature or might be broken. Pseudocode:

# initial value of the temperature
t = float('nan')          
# initial value of minimum temperature, so any measured temp. will be smaller
t_min = float('inf')      
# initial value of maximum temperature, so any measured temp. will be bigger
t_max = float('-inf')     
while True:
    # measure temperature, if sensor is broken t is not changed
    t = measure()     
    # find new minimum temperature
    t_min = min(t_min, t) 
    # find new maximum temperature
    t_max = max(t_max, t) 

The above code works because inf/-inf/nan are valid for min/max operation, so there is no need to deal with exceptions.

If you want the file size of multiple files in a directory, use Files.walkFileTree. You can obtain the size from the BasicFileAttributes that you'll receive.

This is much faster then calling .length() on the result of File.listFiles() or using Files.size() on the result of Files.newDirectoryStream(). In my test cases it was about 100 times faster.

We have been having a discussion back here at the office and we think that trying to automatically correct the way people input names in the current way you want it doing is fraught with possible issues.

We have come up with several cases where different types of auto capitalization fall apart and these are just for English names alone, each language has its own complexities.

Issues with capitalizing the first letter of each name:

• Acronyms such as IBM aren’t allowed to be inputted, would turn into Ibm.

• The Name McDonald would turn into Mcdonald which is incorrect, the same thing is MacDonald too.

• Double barrelled names such as Marie-Tonks would get turned into Marie-tonks.

• Names like O’Connor would turn into O’connor.

For most of these you could write custom rules to deal with it, however, this still has issues with Acronyms as before and you get a new issue:

• Adding in a rule to fix names with Mac such as MacDonald, would the break names such as Macy turning it into MacY.

The only solution we have come up with that is never incorrect is to capitalize every letter which is a brute force method that the DBS appear to also use.

So if you want to automate the process it is as good as impossible to do without a dictionary of every single name and word and how it should be capitlized, If you don't have a rule that covers everything don't use it as it will just annoy your users and prompt people who want to enter their names correctly to go else where.

I encountered the same error. My linker command did have the rt library included -lrt which is correct and it was working for a while. After re-installing Kubuntu it stopped working.

A separate forum thread suggested the -lrt needed to come after the project object files. Moving the -lrt to the end of the command fixed this problem for me although I don't know the details of why.

here is another image url result..working fine...i'm just put only a image path..please check it..

You have to log the responseText:

$.ajax({
    type: 'POST',
    url: 'status.ajax.php',
    data: {
    deviceId: id
  }

.fail(function (data) {
      console.log( "Ajax failed: " + data['responseText'] );
})

I hate using these in-cell formulas and having to fill in a new column, and I finally learned enough to make by own VBA macro to accomplish this effect.

This might not be all that logically different from another answer, but I think the code looks a hell of a lot better:

Dim Switch As Boolean
For Each Cell In Range("B2:B" & ActiveSheet.UsedRange.Rows.Count)
    If Not Cell.Value = Cell.Offset(-1, 0).Value Then Switch = Not (Switch)
    If Switch Then Range("A" & Cell.Row & ":" & Chr(ActiveSheet.UsedRange.Columns.Count + 64) & Cell.Row).Interior.Pattern = xlNone
    If Not Switch Then Range("A" & Cell.Row & ":" & Chr(ActiveSheet.UsedRange.Columns.Count + 64) & Cell.Row).Interior.Color = 14869218
Next

My code here is going by column B, it assumes a header row so it starts at 2, and I use the Chr(x+64) method to get column letters (which won't work past column Z; I haven't yet found a simple-enough method for getting past this).

First, the boolean variable will alternate whenever the value changes to a new one (uses Offset to check cell above), and for each pass the row is checked for either True or False and colors it accordingly.

Step 1: first we have to add permissions in manifest file like

<uses-permission android:name="android.permission.RECEIVE_SMS" android:protectionLevel="signature" />
<uses-permission android:name="android.permission.READ_SMS" />

Step 2: then add service sms receiver class for receiving sms

<receiver android:name="com.aquadeals.seller.services.SmsReceiver">
    <intent-filter>
        <action android:name="android.provider.Telephony.SMS_RECEIVED"/>
    </intent-filter>
</receiver>

Step 3: Add run time permission

private boolean checkAndRequestPermissions()
{
    int sms = ContextCompat.checkSelfPermission(this, Manifest.permission.READ_SMS);

    if (sms != PackageManager.PERMISSION_GRANTED)
    {
        ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.READ_SMS}, REQUEST_ID_MULTIPLE_PERMISSIONS);
        return false;
    }
    return true;
}

Step 4: Add this classes in your app and test Interface class

public interface SmsListener {
   public void messageReceived(String messageText);
}

SmsReceiver.java

public class SmsReceiver extends BroadcastReceiver {
    private static SmsListener mListener;
    public Pattern p = Pattern.compile("(|^)\\d{6}");
    @Override
    public void onReceive(Context context, Intent intent) {
        Bundle data  = intent.getExtras();
        Object[] pdus = (Object[]) data.get("pdus");
        for(int i=0;i<pdus.length;i++)
        {
            SmsMessage smsMessage = SmsMessage.createFromPdu((byte[]) pdus[i]);
            String sender = smsMessage.getDisplayOriginatingAddress();
            String phoneNumber = smsMessage.getDisplayOriginatingAddress();
            String senderNum = phoneNumber ;
            String messageBody = smsMessage.getMessageBody();
            try{
                if(messageBody!=null){
                    Matcher m = p.matcher(messageBody);
                    if(m.find()) {
                        mListener.messageReceived(m.group(0));
                    }
                }
            }
            catch(Exception e){}
        }
    }
    public static void bindListener(SmsListener listener) {
        mListener = listener; 
    }
}

Let us using df.groupby with list and Series constructor

pd.Series({x : y.b.tolist() for x , y in df.groupby('a')})
Out[664]: 
A       [1, 2]
B    [5, 5, 4]
C          [6]
dtype: object

Checkout this working Plunker

<select (change)="onItemChange($event.target.value)">
    <option *ngFor="#value of values" [value]="value.key">{{value.value}}</option>
</select>

If you call your created method in the lifecycle methods like componentDidMount... then you can only use the this.onToggleLoop = this.onToogleLoop.bind(this) and the fat arrow function onToggleLoop = (event) => {...}.

The normal approach of the declaration of a function in the constructor wont work because the lifecycle methods are called earlier.

Here you go:

^[^<>]*$

This will test for string that has no < and no >

If you want to test for a string that may have < and >, but must also have something other you should use just

[^<>] (or ^.*[^<>].*$)

Where [<>] means any of < or > and [^<>] means any that is not of < or >.

And of course the mandatory link.

you have to write only one line in maps_activity.xml

map:cameraZoom="13"

I hope this will solve your problem...

So, your input is 'dan|warrior|54' and you want "warrior". You do this like so:

>>> dan = 'dan|warrior|54'
>>> dan.split('|')[1]
"warrior"

You could use the Chr(int) function

Using Python 3 syntax:

print('%.2f' % number)

A few encoding issues that I had to face couldn't be solved by above solutions. I had to either update my Android Studio or run test cases using following command in the AS terminal.

gradlew clean assembleDebug testDebug

P.S your encoding settings for IDE and project should match.

Hope it helps !

In java, there are two types of parameters, implicit parameters and explicit parameters. Explicit parameters are the arguments passed into a method. The implicit parameter of a method is the instance that the method is called from. Arguments are simply one of the two types of parameters.

If you look at the output you receive from print() and also in your Traceback, you'll see the value you get back is not a string, it's a bytes object (prefixed by b):

b'{\n  "note":"This file    .....

If you fetch the URL using a tool such as curl -v, you will see that the content type is

Content-Type: application/json; charset=utf-8

So it's JSON, encoded as UTF-8, and Python is considering it a byte stream, not a simple string. In order to parse this, you need to convert it into a string first.

Change the last line of code to this:

info = json.loads(js.decode("utf-8"))

In a ColdFusion environment, one thing that will cause an error, even with well-formed JSON, is having Enable Request Debugging Output turned on in the ColdFusion Administrator (under Debugging & Logging > Debug Output Settings). Debugging information will be returned with the JSON data and will thus make it invalid.

Unlike many languages, Kotlin distinguishes between mutable and immutable collections (lists, sets, maps, etc). Precise control over exactly when collections can be edited is useful for eliminating bugs, and for designing good APIs.

https://kotlinlang.org/docs/reference/collections.html

You'll need to use a MutableList list.

class TempClass {
    var myList: MutableList<Int> = mutableListOf<Int>()
    fun doSomething() {
        // myList = ArrayList<Int>() // initializer is redundant
        myList.add(10)
        myList.remove(10)
    }
}

MutableList<Int> = arrayListOf() should also work.

if your SQL query is this

SELECT id,name,roll FROM student WHERE name='Amit' AND roll='7'

then rawQuery will be

String query="SELECT id, name, roll FROM student WHERE name = ? AND roll = ?";
String[] selectionArgs = {"Amit","7"} 
db.rawQuery(query, selectionArgs);

The above final .htaccess and Test A,B,C,D,E did not work for me. I just used below 2 lines code and it works in my WordPress website:

RewriteCond %{SERVER_PORT} 80 
RewriteRule ^(.*)$ https://www.thehotskills.com/$1 [R=301,L]

I'm not sure where I was making the mistake but this page helped me out.

I wrote this function below where you can change the name of a current key name to a new one.

def change_dictionary_key_name(dict_object, old_name, new_name):
    '''
    [PARAMETERS]: 
        dict_object (dict): The object of the dictionary to perform the change
        old_name (string): The original name of the key to be changed
        new_name (string): The new name of the key
    [RETURNS]:
        final_obj: The dictionary with the updated key names
    Take the dictionary and convert its keys to a list.
    Update the list with the new value and then convert the list of the new keys to 
    a new dictionary
    '''
    keys_list = list(dict_object.keys())
    for i in range(len(keys_list)):
        if (keys_list[i] == old_name):
            keys_list[i] = new_name

    final_obj = dict(zip(keys_list, list(dict_object.values()))) 
    return final_obj

Assuming a JSON you can call it and rename it by the following line:

data = json.load(json_file)
for item in data:
    item = change_dictionary_key_name(item, old_key_name, new_key_name)

Conversion from list to dictionary keys has been found here:

I came across this issue recently. I used PuPHPet to generate a config.

To connect to MySQL through SSH, the "vagrant" password was not working for me, instead I had to authenticate through the SSH key file.

To connect with MySQL Workbench

Connection method

Standard TCP/IP over SSH

SSH

Hostname: 127.0.0.1:2222 (forwarded SSH port)
Username: vagrant
Password: (do not use)
SSH Key File: C:\vagrantpath\puphpet\files\dot\ssh\insecure_private_key
              (Locate your insercure_private_key)

MySQL

Server Port: 3306
username: (root, or username)
password: (password)

Test the connection.

In SQLServer Management Studio:

Tools -> Options -> Designers -> Table and Database Designers

Unselect Prevent saving changes that require table re-creation.

Now you can reorder the table.

Also instead of adding each file manually, we could do something like:

git add --all

OR

git add -A

This will also remove any files not present or deleted (Tracked files in the current working directory which are now absent).

If you only want to add files which are tracked and have changed, you would want to do

git add -u

What is the difference between git add . & git add --all?

Try this: ioreg -p IOUSB -l -b | grep -E "@|PortNum|USB Serial Number"

Try this:

function createcodes() {

    $('.authors-list tr').each(function () {
        //processing this row
        //how to process each cell(table td) where there is checkbox
        $(this).find('td input:checked').each(function () {

             // it is checked, your code here...
        });
    });
}

You're missing the entire point of fmin and fmax. It was included in C99 so that modern CPUs could use their native (read SSE) instructions for floating point min and max and avoid a test and branch (and thus a possibly mis-predicted branch). I've re-written code that used std::min and std::max to use SSE intrinsics for min and max in inner loops instead and the speed-up was significant.

According to @Enno Gröper 's post, I've tried the SSLContext constructor and it works well on my machine. code as below:

import ssl
ctx = ssl.SSLContext(ssl.PROTOCOL_SSLv23)
urllib2.urlopen("https://your-test-server.local", context=ctx)

if you need opener, just added this context like:

opener = urllib2.build_opener(urllib2.HTTPSHandler(context=ctx))

NOTE: all above test environment is python 2.7.12. I use PROTOCOL_SSLv23 here since the doc says so, other protocol might also works but depends on your machine and remote server, please check the doc for detail.

SELECT Subject, CONVERT(varchar(10),DeliveryDate) as DeliveryDate
from Email_Administration 
where MerchantId =@ MerchantID

1. use single quotes for strings
2. do NOT put single quotes around table names(use ` instead)
3. do NOT put single quotes around numbers (you can, but it's harder to read)
4. do NOT put AND between ORDER BY and LIMIT
5. do NOT put = between ORDER BY, LIMIT keywords and condition

So you query will look like:

SELECT post_datetime 
FROM post 
WHERE type = 'published' 
ORDER BY post_datetime DESC 
LIMIT 3

path = "/folderA/folderB/folderC/folderD/"
last = path.split('/').pop()

In my case I had to do this:

for index, user in enumerate(users):
    table_body.append([])
    table_body[index].append(user.user.id)
    table_body[index].append(user.user.username)

Output:

[[1, 'john'], [2, 'bill']]

If you wait until the page is loaded, and then set the button's display to none, that should work. Then you can make it visible at a later point.

As @martin and this answer explained, it is complicated. There is no bullet-proof way of getting the client's ip address.

The best that you can do is to try to parse "X-Forwarded-For" and rely on request.getRemoteAddr();

public static String getClientIpAddress(HttpServletRequest request) {
    String xForwardedForHeader = request.getHeader("X-Forwarded-For");
    if (xForwardedForHeader == null) {
        return request.getRemoteAddr();
    } else {
        // As of https://en.wikipedia.org/wiki/X-Forwarded-For
        // The general format of the field is: X-Forwarded-For: client, proxy1, proxy2 ...
        // we only want the client
        return new StringTokenizer(xForwardedForHeader, ",").nextToken().trim();
    }
}

Not sure if this is the answer you were looking for, but it worked for me. After spinning my wheels in Windows Firewall, I went back into SQL Server Configuration Manager, checked SQL Server Network Configuration, in the protocols for the instance I was working with look at TCP/IP. By default it seems mine was set to disabled, which allowed for instance connections on the local machine but not using SSMS on another machine. Enabling TCP/IP did the trick for me.

Screencast:

I would always encode in UTF-8. From the Wikipedia page on percent encoding:

The generic URI syntax mandates that new URI schemes that provide for the representation of character data in a URI must, in effect, represent characters from the unreserved set without translation, and should convert all other characters to bytes according to UTF-8, and then percent-encode those values. This requirement was introduced in January 2005 with the publication of RFC 3986. URI schemes introduced before this date are not affected.

It seems like because there were other accepted ways of doing URL encoding in the past, browsers attempt several methods of decoding a URI, but if you're the one doing the encoding you should use UTF-8.

It probably shouldn't matter. You are going to get much better performance designing your algorithm to use a fixed number of threads (eg, 4 or 8 if you have 4 or 8 processors). You can do this with work queues, asynchronous IO, or something like libevent.

Here's my step in Ubuntu 16.04 and Tomcat 8.

1. Copy folder /var/lib/tomcat8/webapps/ROOT to your folder.

   cp -r /var/lib/tomcat8/webapps/ROOT /var/lib/tomcat8/webapps/{yourfolder}

2. Add your html, css, js, to your folder.

3. Open "http://localhost:8080/{yourfolder}" in browser

Notes:

1. If you using chrome web browser and did wrong folder before, then clean web browser's cache(or change another name) otherwise (sometimes) it always 404.

2. The folder META-INF with context.xml is needed.

I know that my answer came late but it happens to me today and I solved it with the following approach:

^(([A-Z]+),)+([A-Z]+)$

So the first group (([A-Z]+),)+ will match all the repeated patterns except the final one ([A-Z]+) that will match the final one. and this will be dynamic no matter how many repeated groups in the string.

Or on OS-X the following works for me:

$ gsort --random-sort

There is pretty concise and easy way:

Response.Write("<script>alert('Your text');</script>");

Just surfed in from the web and felt I could contribute. I noticed that with the above code posted by @calethebrewer can result in multiple calls over the selector and unexpected behaviour for example: -

$(document).on('mouseover', '.selector', function() {
   //do something
});
$(document).on('mouseout', '.selector', function() {
   //do something
});

This fiddle http://jsfiddle.net/TWskH/12/ illustraits my point. When animating elements such as in plugins I have found that these multiple triggers result in unintended behavior which may result in the animation or code being called more than is necessary.

My suggestion is to simply replace with mouseenter/mouseleave: -

$(document).on('mouseenter', '.selector', function() {
   //do something
});
$(document).on('mouseleave', '.selector', function() {
   //do something
});

Although this prevented multiple instances of my animation from being called, I eventually went with mouseover/mouseleave as I needed to determine when children of the parent were being hovered over.

Those are users. Check your /etc/passwd.

cd ~username takes you to that user's home directory.

Try File.basename

Returns the last component of the filename given in file_name, which must be formed using forward slashes (``/’’) regardless of the separator used on the local file system. If suffix is given and present at the end of file_name, it is removed.

File.basename("/home/gumby/work/ruby.rb")          #=> "ruby.rb"
File.basename("/home/gumby/work/ruby.rb", ".rb")   #=> "ruby"

In your case:

File.basename("C:\\projects\\blah.dll", ".dll")  #=> "blah"

Using d.Keys()(i) method is a very bad idea, because on each call it will re-create a new array (you will have significant speed reduction).

Here is an analogue of Scripting.Dictionary called "Hash Table" class from @TheTrick, that support such enumerator: http://www.cyberforum.ru/blogs/354370/blog2905.html

Dim oDict As clsTrickHashTable

Sub aaa()
    Set oDict = New clsTrickHashTable

    oDict.Add "a", "aaa"
    oDict.Add "b", "bbb"

    For i = 0 To oDict.Count - 1
        Debug.Print oDict.Keys(i) & " - " & oDict.Items(i)
    Next
End Sub

Now, I just started programing about a week ago, so nothing fancy, but I had this as a problem and came up with this, which may be easier for people who are just getting into programing to understand. It uses Euclid's method like in previous examples.

public class GCD {
  public static void main(String[] args){
    int x = Math.max(Integer.parseInt(args[0]),Integer.parseInt(args[1]));    
    int y = Math.min(Integer.parseInt(args[0]),Integer.parseInt(args[1]));     
    for (int r = x % y; r != 0; r = x % y){
      x = y;
      y = r;
    }
    System.out.println(y);
  }
}

I believe it's because #ID styles trump .class styles when computing the final style of an element. Try changing your li from class to id, or you can try adding !important to your class, like this:

li.sub-navigation-home-news
{
    color: #C1C1C1; !important

AFAIK, there is no method that does this in the framework. Even if there was support for something like this in the framework, it would essentially be doing the same thing. And that would be looking at each cell in the DataRow to see if it is empty.

import socket
from threading import *

serversocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
host = "192.168.1.3"
port = 8000
print (host)
print (port)
serversocket.bind((host, port))

class client(Thread):
    def __init__(self, socket, address):
        Thread.__init__(self)
        self.sock = socket
        self.addr = address
        self.start()

    def run(self):
        while 1:
            print('Client sent:', self.sock.recv(1024).decode())
            self.sock.send(b'Oi you sent something to me')

serversocket.listen(5)
print ('server started and listening')
while 1:
    clientsocket, address = serversocket.accept()
    client(clientsocket, address)

This is a very VERY simple design for how you could solve it. First of all, you need to either accept the client (server side) before going into your while 1 loop because in every loop you accept a new client, or you do as i describe, you toss the client into a separate thread which you handle on his own from now on.

That's correct, your response is an object with fields:

{
    "page": 1,
    "results": [ ... ]
}

So you in fact want to iterate the results field only:

this.data = res.json()['results'];

... or even easier:

this.data = res.json().results;

breast$class <- as.numeric(as.character(breast$class))

If you have many columns to convert to numeric

indx <- sapply(breast, is.factor)
breast[indx] <- lapply(breast[indx], function(x) as.numeric(as.character(x)))

Another option is to use stringsAsFactors=FALSE while reading the file using read.table or read.csv

Just in case, other options to create/change columns

 breast[,'class'] <- as.numeric(as.character(breast[,'class']))

or

 breast <- transform(breast, class=as.numeric(as.character(breast)))

Sometimes the column you are looking for may be part of the name of many other things that you are not interested in.

For example I was recently looking for a column called "BQR", which also forms part of many other columns such as "BQR_OWNER", "PROP_BQR", etc.

So I would like to have the checkbox that word processors have to indicate "Whole words only".

Unfortunately LIKE has no such functionality, but REGEXP_LIKE can help.

SELECT *
  FROM user_source
 WHERE regexp_like(text, '(\s|\.|,|^)bqr(\s|,|$)');

This is the regular expression to find this column and exclude the other columns with "BQR" as part of the name:

(\s|\.|,|^)bqr(\s|,|$)

The regular expression matches white-space (\s), or (|) period (.), or (|) comma (,), or (|) start-of-line (^), followed by "bqr", followed by white-space, comma or end-of-line ($).

Without annotations, inferred property name (to match from JSON) would be "set", and not -- as seems to be the intent -- "isSet". This is because as per Java Beans specification, methods of form "isXxx" and "setXxx" are taken to mean that there is logical property "xxx" to manage.

-> Testing the app with maximum number of user and input is defined as load testing. While testing the app with more than maximum number of user and input is defined as stress testing.

->In Load testing we measure the system performance based on a volume of users. While in Stress testing we measure the breakpoint of a system.

->Load Testing is testing the application for a given load requirements which may include any of the following criteria:

 .Total number of users.

 .Response Time

 .Through Put

Some parameters to check State of servers/application.

-> While stress testing is testing the application for unexpected load. It includes

 .Vusers

 .Think-Time

Example:

If an app is build for 500 users, then for load testing we check up to 500 users and for stress testing we check greater than 500.

Displaying an Image in WPF is much easier than that. Try this:

<Image Source="{Binding DisplayedImagePath}" HorizontalAlignment="Left" 
    Margin="0,0,0,0" Name="image1" Stretch="Fill" VerticalAlignment="Bottom" 
    Grid.Row="8" Width="200"  Grid.ColumnSpan="2" />

And the property can just be a string:

public string DisplayedImage 
{
    get { return @"C:\Users\Public\Pictures\Sample Pictures\Chrysanthemum.jpg"; }
}

Although you really should add your images to a folder named Images in the root of your project and set their Build Action to Resource in the Properties Window in Visual Studio... you could then access them using this format:

public string DisplayedImage 
{
    get { return "/AssemblyName;component/Images/ImageName.jpg"; }
}

UPDATE >>>

As a final tip... if you ever have a problem with a control not working as expected, simply type 'WPF', the name of that control and then the word 'class' into a search engine. In this case, you would have typed 'WPF Image Class'. The top result will always be MSDN and if you click on the link, you'll find out all about that control and most pages have code examples as well.

UPDATE 2 >>>

If you followed the examples from the link to MSDN and it's not working, then your problem is not the Image control. Using the string property that I suggested, try this:

<StackPanel>
    <Image Source="{Binding DisplayedImagePath}" />
    <TextBlock Text="{Binding DisplayedImagePath}" />
</StackPanel>

If you can't see the file path in the TextBlock, then you probably haven't set your DataContext to the instance of your view model. If you can see the text, then the problem is with your file path.

UPDATE 3 >>>

In .NET 4, the above Image.Source values would work. However, Microsoft made some horrible changes in .NET 4.5 that broke many different things and so in .NET 4.5, you'd need to use the full pack path like this:

<Image Source="pack://application:,,,/AssemblyName;component/Images/image_to_use.png">

For further information on pack URIs, please see the Pack URIs in WPF page on Microsoft Docs.

1) The most simple way would be using WMPLib

WMPLib.WindowsMediaPlayer Player;

private void PlayFile(String url)
{
    Player = new WMPLib.WindowsMediaPlayer();
    Player.PlayStateChange += Player_PlayStateChange;
    Player.URL = url;
    Player.controls.play();
}

private void Player_PlayStateChange(int NewState)
{
    if ((WMPLib.WMPPlayState)NewState == WMPLib.WMPPlayState.wmppsStopped)
    {
        //Actions on stop
    }
}

2) Alternatively you can use the open source library NAudio. It can play mp3 files using different methods and actually offers much more than just playing a file.

This is as simple as

using NAudio;
using NAudio.Wave;

IWavePlayer waveOutDevice = new WaveOut();
AudioFileReader audioFileReader = new AudioFileReader("Hadouken! - Ugly.mp3");

waveOutDevice.Init(audioFileReader);
waveOutDevice.Play();

Don't forget to dispose after the stop

waveOutDevice.Stop();
audioFileReader.Dispose();
waveOutDevice.Dispose();

The latest 2020 build doesn't have the shorten command line option by default we need to add that option from the configuration.

Run > Edit Configurations > Select the corresponding run configuration and click on Modify options for adding the shorten command-line configuration to the UI.

Select the shorten command line option

Now choose jar manifest from the shorten command line option

Here is a one-liner:

import os

[val for sublist in [[os.path.join(i[0], j) for j in i[2]] for i in os.walk('./')] for val in sublist]
# Meta comment to ease selecting text

The outer most val for sublist in ... loop flattens the list to be one dimensional. The j loop collects a list of every file basename and joins it to the current path. Finally, the i loop iterates over all directories and sub directories.

This example uses the hard-coded path ./ in the os.walk(...) call, you can supplement any path string you like.

Note: os.path.expanduser and/or os.path.expandvars can be used for paths strings like ~/

Extending this example:

Its easy to add in file basename tests and directoryname tests.

For Example, testing for *.jpg files:

... for j in i[2] if j.endswith('.jpg')] ...

Additionally, excluding the .git directory:

... for i in os.walk('./') if '.git' not in i[0].split('/')]

In short, vmalloc and kmalloc both could fix fragmentation. vmalloc use memory mappings to fix external fragmentation; kmalloc use slab to fix internal frgamentation. Fot what it's worth, kmalloc also has many other advantages.

This doesn't work. only one value is ever pre-selected even though both options are available in the list only the first is shown ('#searchproject').select2('val', ['New Co-location','Expansion']);

If nothing makes sense, this error can also be caused by PHP Error that is embedded inside html/javascript, such as the one below

<br />
<b>Deprecated</b>:  mysql_connect(): The mysql extension is deprecated and will be removed in the future: use mysqli or PDO instead in <b>C:\Projects\rwp\demo\en\super\ge.php</b> on line <b>54</b><br />
var zNodes =[{ id:1, pId:0, name:"ACE", url: "/ace1.php", target:"_self", open:true}

Not the <br /> etc in the code that are inserted into html by PHP is causing the error. To fix this kind of error (suppress warning), used this code in the start

error_reporting(E_ERROR | E_PARSE);

To view, right click on page, "view source" and then examine complete html to spot this error.

${empty companies}

This checks for null and empty lists/collections/arrays. It doesn't get you the length but it satisfies the example in the OP. If you can get away with it this is just cleaner than importing a tag library and its crusty syntax like gt.

This is the function I use to modify the exception message in Python 2.7 and 3.x while preserving the original traceback. It requires six

def reraise_modify(caught_exc, append_msg, prepend=False):
    """Append message to exception while preserving attributes.

    Preserves exception class, and exception traceback.

    Note:
        This function needs to be called inside an except because
        `sys.exc_info()` requires the exception context.

    Args:
        caught_exc(Exception): The caught exception object
        append_msg(str): The message to append to the caught exception
        prepend(bool): If True prepend the message to args instead of appending

    Returns:
        None

    Side Effects:
        Re-raises the exception with the preserved data / trace but
        modified message
    """
    ExceptClass = type(caught_exc)
    # Keep old traceback
    traceback = sys.exc_info()[2]
    if not caught_exc.args:
        # If no args, create our own tuple
        arg_list = [append_msg]
    else:
        # Take the last arg

If you need one item to be left aligned (like a header) but then multiple items right aligned (like 3 images), then you would do something like this:

h1 {
   flex-basis: 100%; // forces this element to take up any remaining space
}

img {
   margin: 0 5px; // small margin between images
   height: 50px; // image width will be in relation to height, in case images are large - optional if images are already the proper size
}

Here's what that will look like (only relavent CSS was included in snippet above)

I'll try to keep this short, I've done this a few months ago for a game I was trying to build, it does a UDP "Client-Server" connection that acts like TCP, you can send (message) (message + object) using this. I've done some testing with it and it works just fine, feel free to modify it if needed.

The answer did not work for me. I dont know how it got so many votes. Though it helped in pointing me in a direction.

This is the answer that worked for me:

foreach (var x in jobj)
{
    var key = ((JProperty) (x)).Name;
    var jvalue = ((JProperty)(x)).Value ;
}

Think of the null as "unknown" in that case (or "does not exist"). In either of those cases, you can't say that they are equal, because you don't know the value of either of them. So, null=null evaluates to not true (false or null, depending on your system), because you don't know the values to say that they ARE equal. This behavior is defined in the ANSI SQL-92 standard.

EDIT: This depends on your ansi_nulls setting. if you have ANSI_NULLS off, this WILL evaluate to true. Run the following code for an example...

set ansi_nulls off

if null = null
    print 'true'
else
    print 'false'


set ansi_nulls ON

if null = null
    print 'true'
else
    print 'false'

As you noticed, these are Makefile {macros or variables}, not compiler options. They implement a set of conventions. (Macros is an old name for them, still used by some. GNU make doc calls them variables.)

The only reason that the names matter is the default make rules, visible via make -p, which use some of them.

If you write all your own rules, you get to pick all your own macro names.

In a vanilla gnu make, there's no such thing as CCFLAGS. There are CFLAGS, CPPFLAGS, and CXXFLAGS. CFLAGS for the C compiler, CXXFLAGS for C++, and CPPFLAGS for both.

Why is CPPFLAGS in both? Conventionally, it's the home of preprocessor flags (-D, -U) and both c and c++ use them. Now, the assumption that everyone wants the same define environment for c and c++ is perhaps questionable, but traditional.

P.S. As noted by James Moore, some projects use CPPFLAGS for flags to the C++ compiler, not flags to the C preprocessor. The Android NDK, for one huge example.

you can try writing the command using 'sudo':

sudo mkdir DirName

This is an old question, but one that is frequently visited and clear recommendations are now available from RFC 7303 which obsoletes RFC3023. In a nutshell (section 9.2):

The registration information for text/xml is in all respects the same
as that given for application/xml above (Section 9.1), except that
the "Type name" is "text".

In my case some of the projects in the solution were targeted to Any CPU, some of them to x86. The compilation error disappeared after unifying the platform target across the solution.

The ggplot2 package takes a little bit of learning, but the results look really nice, you get nice legends, plus many other nice features, all without having to write much code.

require(ggplot2)
require(reshape2)
df <- data.frame(time = 1:10,
                 a = cumsum(rnorm(10)),
                 b = cumsum(rnorm(10)),
                 c = cumsum(rnorm(10)))
df <- melt(df ,  id.vars = 'time', variable.name = 'series')

# plot on same grid, each series colored differently -- 
# good if the series have same scale
ggplot(df, aes(time,value)) + geom_line(aes(colour = series))

# or plot on different plots
ggplot(df, aes(time,value)) + geom_line() + facet_grid(series ~ .)

To print the current working Directory i.e. pwd just type command like:

echo "the PWD is : ${pwd}"

public void keyPressed(KeyEvent e) {
    if (e.getKeyCode() == KeyEvent.VK_RIGHT ) {
            //Right arrow key code
    } else if (e.getKeyCode() == KeyEvent.VK_LEFT ) {
            //Left arrow key code
    } else if (e.getKeyCode() == KeyEvent.VK_UP ) {
            //Up arrow key code
    } else if (e.getKeyCode() == KeyEvent.VK_DOWN ) {
            //Down arrow key code
    }

    repaint();
}

The KeyEvent codes are all a part of the API: http://docs.oracle.com/javase/7/docs/api/java/awt/event/KeyEvent.html

In Oracle 12.1 and below: 30 char (bytes, really, as has been stated).

But do not trust me; try this for yourself:

Table created.



SQL> create table I234567890123456789012345678901(my_id number);


ERROR at line 1:

Updated: as stated above, in Oracle 12.2 and later, the maximum object name length is now 128 bytes.

Here the solution http://www.wacdesigns.com/2008/10/03/merge-pdf-files-using-c It use free open source iTextSharp library http://sourceforge.net/projects/itextsharp

If it is possible to change the sequence of the lines you could do:

1. sort line with Edit -> Line Operations -> Sort Lines Lexicographically ascending
2. do a Find / Replace:
   • Find What: ^(.*\r?\n)\1+
   • Replace with: (Nothing, leave empty)
   • Check Regular Expression in the lower left
   • Click Replace All

How it works: The sorting puts the duplicates behind each other. The find matches a line ^(.*\r?\n) and captures the line in \1 then it continues and tries to find \1 one or more times (+) behind the first match. Such a block of duplicates (if it exists) is replaced with nothing.

The \r?\n should deal nicely with Windows and Unix lineendings.

Answer for a slightly different problem:

You have a sequence of raw unicode that was saved into a str variable:

s_str: str = "\x00\x01\x00\xc0\x01\x00\x00\x00\x04"

You need to be able to get the byte literal of that unicode (for struct.unpack(), etc.)

s_bytes: bytes = b'\x00\x01\x00\xc0\x01\x00\x00\x00\x04'

Solution:

s_new: bytes = bytes(s, encoding="raw_unicode_escape")

Reference (scroll up for standard encodings):

Python Specific Encodings

You can use anonymous types for example:

  var empData = from res in _db.EMPLOYEEs
                where res.EMAIL == givenInfo || res.USER_NAME == givenInfo
                select new { res.EMAIL, res.USER_NAME };

In C, use

#include <float.h>

const double lowest_double = -DBL_MAX;

In C++pre-11, use

#include <limits>

const double lowest_double = -std::numeric_limits<double>::max();

In C++11 and onwards, use

#include <limits>

constexpr double lowest_double = std::numeric_limits<double>::lowest();

There are many quirks in the way browsers handle XMLHttpRequest, this JS code will work across all browsers:
https://github.com/ilinsky/xmlhttprequest

This JS code converts XML into easy to use JavaScript objects:
http://www.terracoder.com/index.php/xml-objectifier

The JS code above can be included in the page to meet your no external library requirement.

var symbol = "MSFT"; 
var xmlhttp = new XMLHttpRequest();
xmlhttp.open("POST", "http://www.webservicex.net/stockquote.asmx?op=GetQuote",true);
xmlhttp.onreadystatechange=function() {
 if (xmlhttp.readyState == 4) {
  alert(xmlhttp.responseText);
  // http://www.terracoder.com convert XML to JSON 
  var json = XMLObjectifier.xmlToJSON(xmlhttp.responseXML);
  var result = json.Body[0].GetQuoteResponse[0].GetQuoteResult[0].Text;
  // Result text is escaped XML string, convert string to XML object then convert to JSON object
  json = XMLObjectifier.xmlToJSON(XMLObjectifier.textToXML(result));
  alert(symbol + ' Stock Quote: $' + json.Stock[0].Last[0].Text); 
 }
}
xmlhttp.setRequestHeader("SOAPAction", "http://www.webserviceX.NET/GetQuote");
xmlhttp.setRequestHeader("Content-Type", "text/xml");
var xml = '<?xml version="1.0" encoding="utf-8"?>' +
 '<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" ' +
                'xmlns:xsd="http://www.w3.org/2001/XMLSchema" ' +
                'xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">' + 
   '<soap:Body> ' +
     '<GetQuote xmlns="http://www.webserviceX.NET/"> ' +
       '<symbol>' + symbol + '</symbol> ' +
     '</GetQuote> ' +
   '</soap:Body> ' +
 '</soap:Envelope>';
xmlhttp.send(xml);
// ...Include Google and Terracoder JS code here...

Two other options:

• JavaScript SOAP client:
  http://www.guru4.net/articoli/javascript-soap-client/en/

• Generate JavaScript from a WSDL:
  https://cwiki.apache.org/confluence/display/CXF20DOC/WSDL+to+Javascript

There's a much simpler way to accomplish this feat, just hijack the onclick attribute of a dummy element to force a return of your string as a JavaScript object:

var jsonify = (function(div){
  return function(json){
    div.setAttribute('onclick', 'this.__json__ = ' + json);
    div.click();
    return div.__json__;
  }
})(document.createElement('div'));

// Let's say you had a string like '{ one: 1 }' (malformed, a key without quotes)
// jsonify('{ one: 1 }') will output a good ol' JS object ;)

Here's a demo: http://codepen.io/csuwldcat/pen/dfzsu (open your console)

The following is a nice generic alternative to valueOf()

public static RandomEnum getEnum(String value) {
  for (RandomEnum re : RandomEnum.values()) {

    }
  }
  throw new IllegalArgumentException("Invalid RandomEnum value: " + value);
}

There should be one-- and preferably only one --obvious way to do it.

This is a modern Promise version of the previous one, using a Promise.all approach to resolve all promises when all files have been read:

/**
 * Promise all
 * @author Loreto Parisi (loretoparisi at gmail dot com)
 */
function promiseAllP(items, block) {
    var promises = [];
    items.forEach(function(item,index) {
        promises.push( function(item,i) {
            return new Promise(function(resolve, reject) {
                return block.apply(this,[item,index,resolve,reject]);
            });
        }(item,index))
    });
    return Promise.all(promises);
} //promiseAll

/**
 * read files
 * @param dirname string
 * @return Promise
 * @author Loreto Parisi (loretoparisi at gmail dot com)
 * @see http://stackoverflow.com/questions/10049557/reading-all-files-in-a-directory-store-them-in-objects-and-send-the-object
 */
function readFiles(dirname) {
    return new Promise((resolve, reject) => {
        fs.readdir(dirname, function(err, filenames) {
            if (err) return reject(err);
            promiseAllP(filenames,
            (filename,index,resolve,reject) =>  {
                fs.readFile(path.resolve(dirname, filename), 'utf-8', function(err, content) {
                    if (err) return reject(err);
                    return resolve({filename: filename, contents: content});
                });
            })
            .then(results => {
                return resolve(results);
            })
            .catch(error => {
                return reject(error);
            });
        });
  });
}

How to Use It:

Just as simple as doing:

readFiles( EMAIL_ROOT + '/' + folder)
.then(files => {
    console.log( "loaded ", files.length );
    files.forEach( (item, index) => {
        console.log( "item",index, "size ", item.contents.length);
    });
})
.catch( error => {
    console.log( error );
});

Supposed that you have another list of folders you can as well iterate over this list, since the internal promise.all will resolve each of then asynchronously:

var folders=['spam','ham'];
folders.forEach( folder => {
    readFiles( EMAIL_ROOT + '/' + folder)
    .then(files => {
        console.log( "loaded ", files.length );
        files.forEach( (item, index) => {
            console.log( "item",index, "size ", item.contents.length);
        });
    })
    .catch( error => {
        console.log( error );
    });
});

How it Works

The promiseAll does the magic. It takes a function block of signature function(item,index,resolve,reject), where item is the current item in the array, index its position in the array, and resolve and reject the Promise callback functions. Each promise will be pushed in a array at the current index and with the current item as arguments through a anonymous function call:

promises.push( function(item,i) {
        return new Promise(function(resolve, reject) {
            return block.apply(this,[item,index,resolve,reject]);
        });
    }(item,index))

Then all promises will be resolved:

return Promise.all(promises);

This is normally done at compile time (specially for performance reason) by using the header files available from the compiler or create your own. On linux you have the header file "/usr/include/endian.h"

It's \n. When you're reading or writing text mode files, or to stdin/stdout etc, you must use \n, and C will handle the translation for you. When you're dealing with binary files, by definition you are on your own.

Try this:

$(document).ready(function(){
    var yourArray = [];
    $("span.HOEnZb").find("div").each(function(){
        if(($.trim($(this).text()).length>0)){
         yourArray.push($(this).text());
        }
    });
});

DEMO

This worked for me: (notice that java 8 is required)

String requestData = request.getReader().lines().collect(Collectors.joining());
UserJsonParser u = gson.fromJson(requestData, UserJsonParser.class);

UserJsonParse is a class that shows gson how to parse the json formant.

class is like that:

public class UserJsonParser {

    private String username;
    private String name;
    private String lastname;
    private String mail;
    private String pass1;
//then put setters and getters
}

the json string that is parsed is like that:

$jsonData: {    "username": "testuser",    "pass1": "clave1234" }

The rest of values (mail, lastname, name) are set to null

int array[ROW][COLUMN]={1};

This initialises only the first element to 1. Everything else gets a 0.

In the first instance, you're doing the same - initialising the first element to 0, and the rest defaults to 0.

The reason is straightforward: for an array, the compiler will initialise every value you don't specify with 0.

With a char array you could use memset to set every byte, but this will not generally work with an int array (though it's fine for 0).

A general for loop will do this quickly:

for (int i = 0; i < ROW; i++)
  for (int j = 0; j < COLUMN; j++)
    array[i][j] = 1;

Or possibly quicker (depending on the compiler)

for (int i = 0; i < ROW*COLUMN; i++)
  *((int*)a + i) = 1;

Think about what you're asking!

The max of {1, 2, 3, -1, -2, -3} is obviously 3. The max of {2} is obviously 2. But what is the max of the empty set { }? Obviously that is a meaningless question. The max of the empty set is simply not defined. Attempting to get an answer is a mathematical error. The max of any set must itself be an element in that set. The empty set has no elements, so claiming that some particular number is the max of that set without being in that set is a mathematical contradiction.

Just as it is correct behavior for the computer to throw an exception when the programmer asks it to divide by zero, so it is correct behavior for the computer to throw an exception when the programmer asks it to take the max of the empty set. Division by zero, taking the max of the empty set, wiggering the spacklerorke, and riding the flying unicorn to Neverland are all meaningless, impossible, undefined.

Now, what is it that you actually want to do?

Partition the table monthly.That is the best way to handle tables with large daily influx ,be it oracle or MSSQL.

I was running in to a problem with the standard way to do this:

$string = "one";

$float = (float)$string;

echo $float; : ( Prints 0 )

If there isn't a valid number, the parser shouldn't return a number, it should throw an error. (This is a condition I'm trying to catch in my code, YMMV)

To fix this I have done the following:

$string = "one";

$float = is_numeric($string) ? (float)$string : null;

echo $float; : ( Prints nothing )

Then before further processing the conversion, I can check and return an error if there wasn't a valid parse of the string.

You could use string.chars().mapToObj(e -> new String(new char[] {e}));, though this is quite lengthy and only works with java 8. Here are a few more methods:

string.split(""); (Has an extra whitespace character at the beginning of the array if used before Java 8) string.split("|"); string.split("(?!^)"); Arrays.toString(string.toCharArray()).substring(1, string.length() * 3 + 1).split(", ");

The last one is just unnecessarily long, it's just for fun!

Obligatory answer in Swift : NSIndexPath(forRow:row, inSection: section)

You will notice that NSIndexPath.indexPathForRow(row, inSection: section) is not available in swift and you must use the first method to construct the indexPath.

Reverse merge is exactly what you want (see luapyad's answer). Just apply the merge to the erroneously-commited file instead of the entire directory.

You want to have a look at FileField and FieldFile in the Django docs, and especially FieldFile.save().

Basically, a field declared as a FileField, when accessed, gives you an instance of class FieldFile, which gives you several methods to interact with the underlying file. So, what you need to do is:

self.license_file.save(new_name, new_contents)

where new_name is the filename you wish assigned and new_contents is the content of the file. Note that new_contents must be an instance of either django.core.files.File or django.core.files.base.ContentFile (see given links to manual for the details).

The two choices boil down to:

from django.core.files.base import ContentFile, File

# Using File
with open('/path/to/file') as f:
    self.license_file.save(new_name, File(f))

# Using ContentFile
self.license_file.save(new_name, ContentFile('A string with the file content'))

422 Unprocessable Entity Explained Updated: March 6, 2017

What Is 422 Unprocessable Entity?

A 422 status code occurs when a request is well-formed, however, due to semantic errors it is unable to be processed. This HTTP status was introduced in RFC 4918 and is more specifically geared toward HTTP extensions for Web Distributed Authoring and Versioning (WebDAV).

There is some controversy out there on whether or not developers should return a 400 vs 422 error to clients (more on the differences between both statuses below). However, in most cases, it is agreed upon that the 422 status should only be returned if you support WebDAV capabilities.

A word-for-word definition of the 422 status code taken from section 11.2 in RFC 4918 can be read below.

The 422 (Unprocessable Entity) status code means the server understands the content type of the request entity (hence a 415(Unsupported Media Type) status code is inappropriate), and the syntax of the request entity is correct (thus a 400 (Bad Request) status code is inappropriate) but was unable to process the contained instructions.

The definition goes on to say:

For example, this error condition may occur if an XML request body contains well-formed (i.e., syntactically correct), but semantically erroneous, XML instructions.

400 vs 422 Status Codes

Bad request errors make use of the 400 status code and should be returned to the client if the request syntax is malformed, contains invalid request message framing, or has deceptive request routing. This status code may seem pretty similar to the 422 unprocessable entity status, however, one small piece of information that distinguishes them is the fact that the syntax of a request entity for a 422 error is correct whereas the syntax of a request that generates a 400 error is incorrect.

The use of the 422 status should be reserved only for very particular use-cases. In most other cases where a client error has occurred due to malformed syntax, the 400 Bad Request status should be used.

In TF1, the statement x.assign(1) does not actually assign the value 1 to x, but rather creates a tf.Operation that you have to explicitly run to update the variable.* A call to Operation.run() or Session.run() can be used to run the operation:

assign_op = x.assign(1)
sess.run(assign_op)  # or `assign_op.op.run()`
print(x.eval())
# ==> 1

(* In fact, it returns a tf.Tensor, corresponding to the updated value of the variable, to make it easier to chain assignments.)

However, in TF2 x.assign(1) will now assign the value eagerly:

x.assign(1)
print(x.numpy())
# ==> 1

you can try

DocumentBuilder db = DocumentBuilderFactory.newInstance().newDocumentBuilder();
InputSource is = new InputSource();
is.setCharacterStream(new StringReader("<root><node1></node1></root>"));

Document doc = db.parse(is);

refer this http://www.java2s.com/Code/Java/XML/ParseanXMLstringUsingDOMandaStringReader.htm

Your memcpy code is correct.

My guess is you are lacking an include of string.h. So the compiler assumes a wrong prototype of memcpy and thus the warning.

Anyway, you should just assign the structs for the sake of simplicity (as Joachim Pileborg pointed out).

If you're using Intellij on Mac, this setup finally worked for me.

Installations: Intellij

1. Go to Preferences, search for Plugins.
2. Type "Lombok" in the plugin search box. Lombok is a non-bundled plugin, so it won't show at first.
3. Click "Browse" to search for non-bundled plugins
4. The "Lombok Plugin" should show up. Select it.
5. Click the green "Install" button.
6. Click the "Restart Intellij IDEA" button.

Settings:

1. Enable Annotation processor

   • Go to Preferences -> Build, Execution,Deployment -->Preferences -> Compiler -> Annotation Processors
   • File -> Other Settings -> Default Settings -> Compiler -> Annotation Processors

2. Check if Lombok plugin is enabled

   • IntelliJ IDEA-> Preferences -> Other Settings -> Lombok plugin -> Enable Lombok

3. Add Lombok jar in Global Libraries and project dependencies.

   • File --> Project Structure --> Global libraries (Add lombok.jar)

4. File --> Project Structure --> Project Settings --> Modules --> Dependencies Tab = check lombok

5. Restart Intellij

$cfg['Servers'][$i]['auth_type'] = 'cookie';

should work.

From the manual:

auth_type = 'cookie' prompts for a MySQL username and password in a friendly HTML form. This is also the only way by which one can log in to an arbitrary server (if $cfg['AllowArbitraryServer'] is enabled). Cookie is good for most installations (default in pma 3.1+), it provides security over config and allows multiple users to use the same phpMyAdmin installation. For IIS users, cookie is often easier to configure than http.

Best Response for web apis that can easily understand by mobile developers.

This is for "Success" Response

{  
   "ReturnCode":"1",
   "ReturnMsg":"Successfull Transaction",
   "ReturnValue":"",
   "Data":{  
      "EmployeeName":"Admin",
      "EmployeeID":1
   }
}

This is for "Error" Response

{
    "ReturnCode": "4",
    "ReturnMsg": "Invalid Username and Password",
    "ReturnValue": "",
    "Data": {}
}

The easiest way to implement the download is that you direct users to the file location, browsers will do that for you automatically.

You can easily achieve it through:

HttpServletResponse.sendRedirect()

Ubuntu 16.04 comes with PHP7 as the standard, so there are no PHP5 packages

However if you like you can add a PPA to get those packages anyways:

Remove all the stock php packages

List installed php packages with dpkg -l | grep php| awk '{print $2}' |tr "\n" " " then remove unneeded packages with sudo aptitude purge your_packages_here or if you want to directly remove them all use :

sudo aptitude purge `dpkg -l | grep php| awk '{print $2}' |tr "\n" " "`

Add the PPA

sudo add-apt-repository ppa:ondrej/php

Install your PHP Version

sudo apt-get update
sudo apt-get install php5.6

You can install php5.6 modules too ..

Verify your version

sudo php -v

Based on https://askubuntu.com/a/756186/532957 (thanks @AhmedJerbi)

The PDB file is typically used to store debug information. This warning is caused probably because the file vc80.pdb is not found when linking the target object file. Read the MSDN entry on LNK4099 here.

Alternatively, you can turn off debug information generation from the Project Properties > Linker > Debugging > Generate Debug Info field.

How do I emulate the ISNULL() functionality ?

SELECT (Field IS NULL) FROM ...

Use the Date.prototype.setFullYear method to set the year to what you want it to be.

For example:

var aYearFromNow = new Date();
aYearFromNow.setFullYear(aYearFromNow.getFullYear() + 1);

There really isn't another way to work with dates in JavaScript if these methods aren't present in the environment you are working with.

You can call more of 1 function filters in the same ng-repeat filter

<article data-ng-repeat="result in results | filter:search() | filter:filterFn()" class="result">

It's just JSON? You can stringify() JSON:

var obj = {
    cons: [[String, 'some', 'somemore']],
    func: function(param, param2){
        param2.some = 'bla';
    }
};

var text = JSON.stringify(obj);

And parse back to JSON again with parse():

var myVar = JSON.parse(text);

If you have functions in the object, use this to serialize:

function objToString(obj, ndeep) {
  switch(typeof obj){
    case "string": return '"'+obj+'"';
    case "function": return obj.name || obj.toString();
    case "object":
      var indent = Array(ndeep||1).join('\t'), isArray = Array.isArray(obj);
      return ('{['[+isArray] + Object.keys(obj).map(function(key){
           return '\n\t' + indent +(isArray?'': key + ': ' )+ objToString(obj[key], (ndeep||1)+1);
         }).join(',') + '\n' + indent + '}]'[+isArray]).replace(/[\s\t\n]+(?=(?:[^\'"]*[\'"][^\'"]*[\'"])*[^\'"]*$)/g,'');
    default: return obj.toString();
  }
}

Examples:

Serialize:

var text = objToString(obj); //To Serialize Object

Result:

"{cons:[[String,"some","somemore"]],func:function(param,param2){param2.some='bla';}}"

Deserialize:

Var myObj = eval('('+text+')');//To UnSerialize 

Result:

Object {cons: Array[1], func: function, spoof: function}

There's actually a great Google API for this. It takes in a location and returns the timezone for that location. Should be simple enough to create a bash or python script to get the results for each address in a CSV file or database then save the timezone information.

https://developers.google.com/maps/documentation/timezone/start

Request Endpoint:

https://maps.googleapis.com/maps/api/timezone/json?location=38.908133,-77.047119&timestamp=1458000000&key=YOUR_API_KEY

Response:

{
   "dstOffset" : 3600,
   "rawOffset" : -18000,
   "status" : "OK",
   "timeZoneId" : "America/New_York",
   "timeZoneName" : "Eastern Daylight Time"
}

This worked for me

1. try deleting the red colored files
2. delete the files in derived data
3. clean the build folder
4. then try building by using "new build system" from file->workspace settings

I was facing a similar error because the bucket was in region us-west-2 and the URL pattern had bucketname in the path. Once, I changed the URL pattern to have bucketname as URL subdomain to grab the files and it worked.

For eg previous URL was

https://s3.amazonaws.com/bucketname/filePath/filename

Then I replaced it as

https://bucketname.s3.amazonaws.com/filePath/filename

You can simply make use of the DateTime class , OOP Style.

<?php
$date = new DateTime('1:00:00');
$date->add(new DateInterval('PT10H'));
echo $date->format('H:i:s a'); //"prints" 11:00:00 a.m

usually, i would expect this as a 'cascading delete' enforced in a trigger, you would only need to delete the main record, then all the depepndent records would be deleted by the trigger logic.

this logic would be similar to what you have written.

Private Sub CommandButton1_Click()
    Dim fso As Object
    Dim fldrname As String
    Dim fldrpath As String

    Set fso = CreateObject("scripting.filesystemobject")
    fldrname = Format(Now(), "dd-mm-yyyy")
    fldrpath = "C:\Temp\" & fldrname
    If Not fso.FolderExists(fldrpath) Then
        fso.createfolder (fldrpath)
    End If
End Sub

boto3 also has a method for uploading a file directly:

s3 = boto3.resource('s3')    
s3.Bucket('bucketname').upload_file('/local/file/here.txt','folder/sub/path/to/s3key')

http://boto3.readthedocs.io/en/latest/reference/services/s3.html#S3.Bucket.upload_file

I'm afraid your posted example is not working, since X and Y aren't defined. So instead of pcolormesh let's use imshow:

import numpy as np
import matplotlib.pyplot as plt

H = np.array([[1, 2, 3, 4],
              [5, 6, 7, 8],
              [9, 10, 11, 12],
              [13, 14, 15, 16]])  # added some commas and array creation code

fig = plt.figure(figsize=(6, 3.2))

ax = fig.add_subplot(111)
ax.set_title('colorMap')
plt.imshow(H)
ax.set_aspect('equal')

cax = fig.add_axes([0.12, 0.1, 0.78, 0.8])
cax.get_xaxis().set_visible(False)
cax.get_yaxis().set_visible(False)
cax.patch.set_alpha(0)
cax.set_frame_on(False)
plt.colorbar(orientation='vertical')
plt.show()

You can use the stacking index of the div to make it appear on top of anything else. Make it a larger value that other elements and it well be on top of others.

use z-index property. See Specifying the stack level: the 'z-index' property and

Elaborate description of Stacking Contexts

Something like

#divOnTop { z-index: 1000; }

<div id="divOnTop">I am on top</div>

What you have to look out for will be IE6. In IE 6 some elements like <select> will be placed on top of an element with z-index value higher than the <select>. You can have a workaround for this by placing an <iframe> behind the div.

See this Internet Explorer z-index bug?

Cursors may also be used, although it is inefficient. The following stackoverflow post discusses the usage of cursors :

INSERT and UPDATE a record using cursors in oracle

Yo don't need any java code. You just have to :

<ImageView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:adjustViewBounds="true"
    android:scaleType="centerCrop" />

The key is in the match parent for width and height

Actually there are 3 places where gradle.properties can be placed:

1. Under gradle user home directory defined by the GRADLE_USER_HOME environment variable, which if not set defaults to USER_HOME/.gradle
2. The sub-project directory (myProject2 in your case)
3. The root project directory (under myProject)

Gradle looks for gradle.properties in all these places while giving precedence to properties definition based on the order above. So for example, for a property defined in gradle user home directory (#1) and the sub-project (#2) its value will be taken from gradle user home directory (#1).

You can find more details about it in gradle documentation here.

Try using this : iframeTracker jQuery Plugin, like that :

jQuery(document).ready(function($){
    $('.iframe_wrap iframe').iframeTracker({
        blurCallback: function(){
            // Do something when iframe is clicked (like firing an XHR request)
        }
    });
});

In addition you can use via data attribute

<button type="button" data-toggle="modal" data-target="#myModal">Launch modal</button>

In this particular case you don't need to write javascript.

You can see more here: http://getbootstrap.com/2.3.2/javascript.html#modals

try this:

asort($array_to_sort, SORT_NUMERIC);

for reference see this: http://php.net/manual/en/function.asort.php

see various sort flags here: http://www.php.net/manual/en/function.sort.php

I'm not sure if this breaks any rules but

sudo bash script.sh

seems to work for me.

With Spring MVC 4.2.1.RELEASE, you need to use the new Jackson2 dependencies as below for the Deserializer to work.

Dont use this

<dependency>  
            <groupId>org.codehaus.jackson</groupId>  
            <artifactId>jackson-mapper-asl</artifactId>  
            <version>1.9.12</version>  
        </dependency>  

Use this instead.

<dependency>
            <groupId>com.fasterxml.jackson.core</groupId>
            <artifactId>jackson-annotations</artifactId>
            <version>2.2.2</version>
        </dependency>
        <dependency>
            <groupId>com.fasterxml.jackson.core</groupId>
            <artifactId>jackson-core</artifactId>
            <version>2.2.2</version>
        </dependency>
        <dependency>
            <groupId>com.fasterxml.jackson.core</groupId>
            <artifactId>jackson-databind</artifactId>
            <version>2.2.2</version>
        </dependency>  

Also use com.fasterxml.jackson.databind.JsonDeserializer and com.fasterxml.jackson.databind.annotation.JsonDeserialize for the deserialization and not the classes from org.codehaus.jackson

When you insert ANY variable into HTML, unless you want the browser to interpret the variable itself as HTML, it's best to use htmlspecialchars() on it. Among other things, it prevents hackers from inserting arbitrary HTML in your page.

The value of $_SERVER['PHP_SELF'] is taken directly from the URL entered in the browser. Therefore if you use it without htmlspecialchars(), you're allowing hackers to directly manipulate the output of your code.

For example, if I e-mail you a link to http://example.com/"><script>malicious_code_here()</script><span class=" and you have <form action="<?php echo $_SERVER['PHP_SELF'] ?>">, the output will be:

<form action="http://example.com/"><script>malicious_code_here()</script><span class="">

My script will run, and you will be none the wiser. If you were logged in, I may have stolen your cookies, or scraped confidential info from your page.

However, if you used <form action="<?php echo htmlspecialchars($_SERVER['PHP_SELF']) ?>">, the output would be:

<form action="http://example.com/&quot;&gt;&lt;script&gt;cookie_stealing_code()&lt;/script&gt;&lt;span class=&quot;">

When you submitted the form, you'd have a weird URL, but at least my evil script did not run.

On the other hand, if you used <form action="">, then the output would be the same no matter what I added to my link. This is the option I would recommend.

If you care about the speed use ujson (UltraJSON), which has the same API as json:

import ujson
ujson.dumps([{"key": "value"}, 81, True])
# '[{"key":"value"},81,true]'
ujson.loads("""[{"key": "value"}, 81, true]""")
# [{u'key': u'value'}, 81, True]

I use this trick... May won't be accurate on small objects, but I think it's much more accurate for a complex object (like pygame surface) rather than sys.getsizeof()

import pygame as pg
import os
import psutil
import time


process = psutil.Process(os.getpid())
pg.init()    
vocab = ['hello', 'me', 'you', 'she', 'he', 'they', 'we',
         'should', 'why?', 'necessarily', 'do', 'that']

font = pg.font.SysFont("monospace", 100, True)

dct = {}

newMem = process.memory_info().rss  # don't mind this line
Str = f'store ' + f'Nothing \tsurface use about '.expandtabs(15) + \
      f'0\t bytes'.expandtabs(9)  # don't mind this assignment too

usedMem = process.memory_info().rss

for word in vocab:
    dct[word] = font.render(word, True, pg.Color("#000000"))

    time.sleep(0.1)  # wait a moment

    # get total used memory of this script:
    newMem = process.memory_info().rss
    Str = f'store ' + f'{word}\tsurface use about '.expandtabs(15) + \
          f'{newMem - usedMem}\t bytes'.expandtabs(9)

    print(Str)
    usedMem = newMem

On my windows 10, python 3.7.3, the output is:

store hello          surface use about 225280    bytes
store me             surface use about 61440     bytes
store you            surface use about 94208     bytes
store she            surface use about 81920     bytes
store he             surface use about 53248     bytes
store they           surface use about 114688    bytes
store we             surface use about 57344     bytes
store should         surface use about 172032    bytes
store why?           surface use about 110592    bytes
store necessarily    surface use about 311296    bytes
store do             surface use about 57344     bytes
store that           surface use about 110592    bytes

If you are using OSX and have yet to set your locale module setting this first answer will not work you will receive the following error:

Traceback (most recent call last):File "<stdin>", line 1, in <module> File "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/locale.py", line 221, in currency
raise ValueError("Currency formatting is not possible using "ValueError: Currency formatting is not possible using the 'C' locale.

To remedy this you will have to do use the following:

locale.setlocale(locale.LC_ALL, 'en_US')

Parent-Child communication in VueJS

Given a root Vue instance is accessible by all descendants via this.$root, a parent component can access child components via the this.$children array, and a child component can access it's parent via this.$parent, your first instinct might be to access these components directly.

The VueJS documentation warns against this specifically for two very good reasons:

• It tightly couples the parent to the child (and vice versa)
• You can't rely on the parent's state, given that it can be modified by a child component.

The solution is to use Vue's custom event interface

The event interface implemented by Vue allows you to communicate up and down the component tree. Leveraging the custom event interface gives you access to four methods:

1. $on() - allows you to declare a listener on your Vue instance with which to listen to events
2. $emit() - allows you to trigger events on the same instance (self)

Example using $on() and $emit():

const events = new Vue({}),_x000D_
    parentComponent = new Vue({_x000D_
      el: '#parent',_x000D_
      ready() {_x000D_
        events.$on('eventGreet', () => {_x000D_
          this.parentMsg = `I heard the greeting event from Child component ${++this.counter} times..`;_x000D_
        });_x000D_
      },_x000D_
      data: {_x000D_
        parentMsg: 'I am listening for an event..',_x000D_
        counter: 0_x000D_
      }_x000D_
    }),_x000D_
    childComponent = new Vue({_x000D_
      el: '#child',_x000D_
      methods: {_x000D_
      greet: function () {_x000D_
        events.$emit('eventGreet');_x000D_
        this.childMsg = `I am firing greeting event ${++this.counter} times..`;_x000D_
      }_x000D_
    },_x000D_
    data: {_x000D_
      childMsg: 'I am getting ready to fire an event.',_x000D_
      counter: 0_x000D_
    }_x000D_
  });

<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/1.0.28/vue.min.js"></script>_x000D_
_x000D_
<div id="parent">_x000D_
  <h2>Parent Component</h2>_x000D_
  <p>{{parentMsg}}</p>_x000D_
</div>_x000D_
_x000D_
<div id="child">_x000D_
  <h2>Child Component</h2>_x000D_
  <p>{{childMsg}}</p>_x000D_
  <button v-on:click="greet">Greet</button>_x000D_
</div>

Answer taken from the original post: Communicating between components in VueJS

make global function

func convertDateFormat(inputDate: String) -> String {

     let olDateFormatter = DateFormatter()
     olDateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss"

     let oldDate = olDateFormatter.date(from: inputDate)

     let convertDateFormatter = DateFormatter()
     convertDateFormatter.dateFormat = "MMM dd yyyy h:mm a"

     return convertDateFormatter.string(from: oldDate!)
}

Called function and pass value in it

get_OutputStr = convertDateFormat(inputDate: "2019-03-30T05:30:00+0000")

and here is output

Edited: Alias to current java version is /Library/Java/Home

For more information: a link

Following are the build-in constants you can use as per your requirements for getting the paths in Codeigniter:

EXT: The PHP file extension

FCPATH: Path to the front controller (this file) (root of CI)

SELF: The name of THIS file (index.php)

BASEPATH: Path to the system folder

APPPATH: The path to the “application” folder

Thanks.

You can try this:

JSONObject result = new JSONObject("Your string here").getJSONObject("result");
JSONObject map = result.getJSONObject("map");
JSONArray entries= map.getJSONArray("entry");

I hope this helps.

Put this formula in cell d31 and copy down to d39

 =iferror(vlookup(b31,$f$3:$g$12,2,0),"")

Here's what is going on. VLOOKUP:

• Takes a value (here the contents of b31),
• Looks for it in the first column of a range (f3:f12 in the range f3:g12), and
• Returns the value for the corresponding row in a column in that range (in this case, the 2nd column or g3:g12 of the range f3:g12).

As you know, the last argument of VLOOKUP sets the match type, with FALSE or 0 indicating an exact match.

Finally, IFERROR handles the #N/A when VLOOKUP does not find a match.

EDIT: A more generic way of doing this that doesn't rely on the layout type (other than that it is a layout type which supports margins):

public static void setMargins (View v, int l, int t, int r, int b) {
    if (v.getLayoutParams() instanceof ViewGroup.MarginLayoutParams) {
        ViewGroup.MarginLayoutParams p = (ViewGroup.MarginLayoutParams) v.getLayoutParams();
        p.setMargins(l, t, r, b);
        v.requestLayout();
    }
}

You should check the docs for TextView. Basically, you'll want to get the TextView's LayoutParams object, and modify the margins, then set it back to the TextView. Assuming it's in a LinearLayout, try something like this:

TextView tv = (TextView)findViewById(R.id.my_text_view);
LinearLayout.LayoutParams params = (LinearLayout.LayoutParams)tv.getLayoutParams();
params.setMargins(0, 0, 10, 0); //substitute parameters for left, top, right, bottom
tv.setLayoutParams(params);

I can't test it right now, so my casting may be off by a bit, but the LayoutParams are what need to be modified to change the margin.

NOTE

Don't forget that if your TextView is inside, for example, a RelativeLayout, one should use RelativeLayout.LayoutParams instead of LinearLayout.LayoutParams

A more hacky way is to add eg., in boot.tsx the line

import './path/declare_modules.d.ts';

with

declare module 'react-materialize';
declare module 'react-router';
declare module 'flux';

in declare_modules.d.ts

It works but other solutions are better IMO.

keytool -list -v -keystore ~/.android/debug.keystore -alias androiddebugkey -storepass android -keypass android 

Check out this blog post from Nemikor, which should do what you want.

http://blog.nemikor.com/2009/04/18/loading-a-page-into-a-dialog/

Basically, before calling 'open', you 'load' the content from the other page first.

jQuery('#dialog').load('path to my page').dialog('open'); 

If you are using foreignkey then you have to use "on_delete=models.CASCADE" as it will eliminate the complexity developed after deleting the original element from the parent table. As simple as that.

categorie = models.ForeignKey('Categorie', on_delete=models.CASCADE)

Edit 10th Dec 2015: As pointed out in the comments, ssi is deprecated since version 1.8. According to the documentation:

This tag has been deprecated and will be removed in Django 1.10. Use the include tag instead.

In my opinion, the right (best) answer to this question is the one from podshumok, as it explains why the behaviour of include when used along with inheritance.

However, I was somewhat surprised that nobody mentioned the ssi tag provided by the Django templating system, which is specifically designed for inline including an external piece of text. Here, inline means the external text will not be interpreted, parsed or interpolated, but simply "copied" inside the calling template.

Please, refer to the documentation for further details (be sure to check your appropriate version of Django in the selector at the lower right part of the page).

https://docs.djangoproject.com/en/dev/ref/templates/builtins/#ssi

From the documentation:

ssi
Outputs the contents of a given file into the page.
Like a simple include tag, {% ssi %} includes the contents of another file
– which must be specified using an absolute path – in the current page

Beware also of the security implications of this technique and also of the required ALLOWED_INCLUDE_ROOTS define, which must be added to your settings files.

This is what I got from oracle documentation, but it is for oracle 10g release 2:

When you define a NUMBER variable, you can specify its precision (p) and scale (s) so that it is sufficiently, but not unnecessarily, large. Precision is the number of significant digits. Scale can be positive or negative. Positive scale identifies the number of digits to the right of the decimal point; negative scale identifies the number of digits to the left of the decimal point that can be rounded up or down.

The NUMBER data type is supported by Oracle Database standard libraries and operates the same way as it does in SQL. It is used for dimensions and surrogates when a text or INTEGER data type is not appropriate. It is typically assigned to variables that are not used for calculations (like forecasts and aggregations), and it is used for variables that must match the rounding behavior of the database or require a high degree of precision. When deciding whether to assign the NUMBER data type to a variable, keep the following facts in mind in order to maximize performance:

• Analytic workspace calculations on NUMBER variables is slower than other numerical data types because NUMBER values are calculated in software (for accuracy) rather than in hardware (for speed).
• When data is fetched from an analytic workspace to a relational column that has the NUMBER data type, performance is best when the data already has the NUMBER data type in the analytic workspace because a conversion step is not required.
