I think something like this would give you the current CultureInfo:

CultureInfo currentCulture = Thread.CurrentThread.CurrentCulture;

Is that what you're looking for?

Since it basically comes down to heuristics, it may help to use the encoding of previously received files from the same source as a first hint.

Most people (or applications) do stuff in pretty much the same order every time, often on the same machine, so its quite likely that when Bob creates a .csv file and sends it to Mary it'll always be using Windows-1252 or whatever his machine defaults to.

Where possible a bit of customer training never hurts either :-)

I strongly suspect the problem is simply that the current culture of the thread handling the request isn't set appropriately.

You can either set it for the whole request, or specify the culture while formatting. Either way, I would suggest not use string.Format with a composite format unless you really have more than one thing to format (or a wider message). Instead, I'd use:

@price.ToString("C", culture)

It just makes it somewhat simpler.

EDIT: Given your comment, it sounds like you may well want to use a UK culture regardless of the culture of the user. So again, either set the UK culture as the thread culture for the whole request, or possibly introduce your own helper class with a "constant":

public static class Cultures
{
    public static readonly CultureInfo UnitedKingdom = 
        CultureInfo.GetCultureInfo("en-GB");
}

Then:

@price.ToString("C", Cultures.UnitedKingdom)

In my experience, having a "named" set of cultures like this makes the code using it considerably simpler to read, and you don't need to get the string right in multiple places.

Convert.ToDouble(x) can also have a second parameter that indicates the CultureInfo and when you set it to System.Globalization.CultureInfo InvariantCulture the result will allways be the same.

This kind of functionality is built in.

When using a decimal you can use a format string "C" or "c".

decimal dec = 123.00M;
string uk = dec.ToString("C", new CultureInfo("en-GB")); // uk holds "£123.00"
string us = dec.ToString("C", new CultureInfo("en-US")); // us holds "$123.00"

As far as I know, there's a good library called localeplanet for Localization and Internationalization in JavaScript. Furthermore, I think it's native and has no dependencies to other libraries (e.g. jQuery)

Here's the website of library: http://www.localeplanet.com/

Also look at this article by Mozilla, you can find very good method and algorithms for client-side translation: http://blog.mozilla.org/webdev/2011/10/06/i18njs-internationalize-your-javascript-with-a-little-help-from-json-and-the-server/

The common part of all those articles/libraries is that they use a i18n class and a get method (in some ways also defining an smaller function name like _) for retrieving/converting the key to the value. In my explaining the key means that string you want to translate and the value means translated string.
Then, you just need a JSON document to store key's and value's.

For example:

var _ = document.webL10n.get;
alert(_('test'));

And here the JSON:

{ test: "blah blah" }

I believe using current popular libraries solutions is a good approach.

In the answers here, up to now, we find two ways of changing the JRE locale setting:

• Programatically, using Locale.setDefault() (which, in my case, was the solution, since I didn't want to require any action of the user):

  Locale.setDefault(new Locale("pt", "BR"));
  

• Via arguments to the JVM:

  java -jar anApp.jar -Duser.language=pt-BR
  

But, just as reference, I want to note that, on Windows, there is one more way of changing the locale used by the JRE, as documented here: changing the system-wide language.

Note: You must be logged in with an account that has Administrative Privileges.

1. Click Start > Control Panel.

2. Windows 7 and Vista: Click Clock, Language and Region > Region and Language.

   Windows XP: Double click the Regional and Language Options icon.

   The Regional and Language Options dialog box appears.

3. Windows 7: Click the Administrative tab.

   Windows XP and Vista: Click the Advanced tab.

   (If there is no Advanced tab, then you are not logged in with administrative privileges.)

4. Under the Language for non-Unicode programs section, select the desired language from the drop down menu.

5. Click OK.

   The system displays a dialog box asking whether to use existing files or to install from the operating system CD. Ensure that you have the CD ready.

6. Follow the guided instructions to install the files.

7. Restart the computer after the installation is complete.

Certainly on Linux the JRE also uses the system settings to determine which locale to use, but the instructions to set the system-wide language change from distro to distro.

With 4.0, you will need to manage this yourself by setting the culture for each thread as Alexei describes. But with 4.5, you can define a culture for the appdomain and that is the preferred way to handle this. The relevant apis are CultureInfo.DefaultThreadCurrentCulture and CultureInfo.DefaultThreadCurrentUICulture.

BTW, do you plan to only permit the Latin alphabet, or do you also plan to try to validate Chinese, Arabic, Hindi, etc.?

As others have said, don't even try to do this. Step back and ask yourself what you are actually trying to accomplish. Then try to accomplish it without making any assumptions about what people's names are, or what they mean.

UPDATED query:

select id from t where id < (select max(id) from t);

It'll select all but the last row from the table t.

List<T>.Insert(0, item);

Swing has no idea what the preferred, minimum and maximum sizes of the GoBoard should be as you have no components inside of it for it to calculate based on, so it picks a (probably wrong) default. Since you are doing custom drawing here, you should implement these methods

Dimension getPreferredSize()
Dimension getMinumumSize()
Dimension getMaximumSize()

or conversely, call the setters for these methods.

in SQL*Plus you could also use a REFCURSOR variable:

SQL> VARIABLE x REFCURSOR
SQL> DECLARE
  2   V_Sqlstatement Varchar2(2000);
  3  BEGIN
  4   V_Sqlstatement := 'SELECT * FROM DUAL';
  5   OPEN :x for v_Sqlstatement;
  6  End;
  7  /

ProcÚdure PL/SQL terminÚe avec succÞs.

SQL> print x;

D
-
X

Using JQuery would be good;

<a href="#" id="youLink">Call JavaScript </a>



$("#yourLink").click(function(e){
//do what ever you want...
});

This is for extra information.

Imagine this scenario

1. ActivityA launch ActivityB.

2. ActivityB launch a new ActivityAPrime by

   Intent intent = new Intent(getApplicationContext(), ActivityA.class);
   startActivity(intent);
   

3. ActivityAPrime has no relationship with ActivityA.
   In this case the Bundle in ActivityAPrime.onCreate() will be null.

If ActivityA and ActivityAPrime should be the same activity instead of different activities, ActivityB should call finish() than using startActivity().

There's a GROUP Aggregate function, GROUP_CONCAT.

In addition to the already posted answer, I thought I should share a handy trick I use to load all the DLL functions into the program through function pointers, without writing a separate GetProcAddress call for each and every function. I also like to call the functions directly as attempted in the OP.

Start by defining a generic function pointer type:

typedef int (__stdcall* func_ptr_t)();

What types that are used aren't really important. Now create an array of that type, which corresponds to the amount of functions you have in the DLL:

func_ptr_t func_ptr [DLL_FUNCTIONS_N];

In this array we can store the actual function pointers that point into the DLL memory space.

Next problem is that GetProcAddress expects the function names as strings. So create a similar array consisting of the function names in the DLL:

const char* DLL_FUNCTION_NAMES [DLL_FUNCTIONS_N] = 
{
  "dll_add",
  "dll_subtract",
  "dll_do_stuff",
  ...
};

Now we can easily call GetProcAddress() in a loop and store each function inside that array:

for(int i=0; i<DLL_FUNCTIONS_N; i++)
{
  func_ptr[i] = GetProcAddress(hinst_mydll, DLL_FUNCTION_NAMES[i]);

  if(func_ptr[i] == NULL)
  {
    // error handling, most likely you have to terminate the program here
  }
}

If the loop was successful, the only problem we have now is calling the functions. The function pointer typedef from earlier isn't helpful, because each function will have its own signature. This can be solved by creating a struct with all the function types:

typedef struct
{
  int  (__stdcall* dll_add_ptr)(int, int);
  int  (__stdcall* dll_subtract_ptr)(int, int);
  void (__stdcall* dll_do_stuff_ptr)(something);
  ...
} functions_struct;

And finally, to connect these to the array from before, create a union:

typedef union
{
  functions_struct  by_type;
  func_ptr_t        func_ptr [DLL_FUNCTIONS_N];
} functions_union;

Now you can load all the functions from the DLL with the convenient loop, but call them through the by_type union member.

But of course, it is a bit burdensome to type out something like

functions.by_type.dll_add_ptr(1, 1); whenever you want to call a function.

As it turns out, this is the reason why I added the "ptr" postfix to the names: I wanted to keep them different from the actual function names. We can now smooth out the icky struct syntax and get the desired names, by using some macros:

#define dll_add (functions.by_type.dll_add_ptr)
#define dll_subtract (functions.by_type.dll_subtract_ptr)
#define dll_do_stuff (functions.by_type.dll_do_stuff_ptr)

And voilà, you can now use the function names, with the correct type and parameters, as if they were statically linked to your project:

int result = dll_add(1, 1);

Disclaimer: Strictly speaking, conversions between different function pointers are not defined by the C standard and not safe. So formally, what I'm doing here is undefined behavior. However, in the Windows world, function pointers are always of the same size no matter their type and the conversions between them are predictable on any version of Windows I've used.

Also, there might in theory be padding inserted in the union/struct, which would cause everything to fail. However, pointers happen to be of the same size as the alignment requirement in Windows. A static_assert to ensure that the struct/union has no padding might be in order still.

Although ANSI C does not have this mechanism, it is possible to use itoa() as a shortcut:

  char buffer [33];
  itoa (i,buffer,2);
  printf ("binary: %s\n",buffer);

Here's the origin:

itoa in cplusplus reference

It is non-standard C, but K&R mentioned the implementation in the C book, so it should be quite common. It should be in stdlib.h.

In Visual Studio the default stack size is 1 MB i think, so with a recursion depth of 10,000 each stack frame can be at most ~100 bytes which should be sufficient for a DFS algorithm.

Most compilers including Visual Studio let you specify the stack size. On some (all?) linux flavours the stack size isn't part of the executable but an environment variable in the OS. You can then check the stack size with ulimit -s and set it to a new value with for example ulimit -s 16384.

Here's a link with default stack sizes for gcc.

DFS without recursion:

std::stack<Node> dfs;
dfs.push(start);
do {
    Node top = dfs.top();
    if (top is what we are looking for) {
       break;
    }
    dfs.pop();
    for (outgoing nodes from top) {
        dfs.push(outgoing node);
    }
} while (!dfs.empty())

If we assume the date in Excel is in A1 cell formatted as Date and the Unix timestamp should be in a A2 cell formatted as number the formula in A2 should be:

= (A1 * 86400) - 2209075200

where:

86400 is the number of seconds in the day 2209075200 is the number of seconds between 1900-01-01 and 1970-01-01 which are the base dates for Excel and Unix timestamps.

The above is true for Windows. On Mac the base date in Excel is 1904-01-01 and the seconds number should be corrected to: 2082844800

If you are in a loop, let's say that you loop through a list of punctuation characters that you want to remove, you can do something like this:

      private const string PunctuationChars = ".,!?$";
          foreach (var word in words)
                {
                    var word_modified = word;

                    var modified = false;

                    foreach (var punctuationChar in PunctuationChars)
                    {
                        if (word.IndexOf(punctuationChar) > 0)
                        {
                            modified = true;
                            word_modified = word_modified.Replace("" + punctuationChar, "");


                        }
                    }
               //////////MORE CODE
               }

The trick being the following:

word_modified.Replace("" + punctuationChar, "");

How about something like this?

val newDF = df.filter($"B" === "").take(1) match {
  case Array() => df
  case _ => df.withColumn("D", $"B" === "")
}

Using take(1) should have a minimal hit

You need to do encode on tmp[0], not on tmp.

tmp is not a string. It contains a (Unicode) string.

Try running type(tmp) and print dir(tmp) to see it for yourself.

I know the question was about postgresql version 8 but I wrote this simple way here for people who want to get sequences in version 10 and upper

you can use the bellow query

In the Google Maps API v2 Demo there is a MarkerDemoActivity class in which you can see how a custom Image is set to a GoogleMap.

// Uses a custom icon.
mSydney = mMap.addMarker(new MarkerOptions()
    .position(SYDNEY)
    .title("Sydney")
    .snippet("Population: 4,627,300")
    .icon(BitmapDescriptorFactory.fromResource(R.drawable.arrow)));

As this just replaces the marker with an image you might want to use a Canvas to draw more complex and fancier stuff:

Bitmap.Config conf = Bitmap.Config.ARGB_8888;
Bitmap bmp = Bitmap.createBitmap(80, 80, conf);
Canvas canvas1 = new Canvas(bmp);

// paint defines the text color, stroke width and size
Paint color = new Paint();
color.setTextSize(35);
color.setColor(Color.BLACK);

// modify canvas
canvas1.drawBitmap(BitmapFactory.decodeResource(getResources(),
    R.drawable.user_picture_image), 0,0, color);
canvas1.drawText("User Name!", 30, 40, color);

// add marker to Map
mMap.addMarker(new MarkerOptions()
    .position(USER_POSITION)
    .icon(BitmapDescriptorFactory.fromBitmap(bmp))
    // Specifies the anchor to be at a particular point in the marker image.
    .anchor(0.5f, 1));

This draws the Canvas canvas1 onto the GoogleMap mMap. The code should (mostly) speak for itself, there are many tutorials out there how to draw a Canvas. You can start by looking at the Canvas and Drawables from the Android Developer page.

Now you also want to download a picture from an URL.

URL url = new URL(user_image_url);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();   
conn.setDoInput(true);   
conn.connect();     
InputStream is = conn.getInputStream();
bmImg = BitmapFactory.decodeStream(is); 

You must download the image from an background thread (you could use AsyncTask or Volley or RxJava for that).

After that you can replace the BitmapFactory.decodeResource(getResources(), R.drawable.user_picture_image) with your downloaded image bmImg.

Take a very common pattern. Class Factory makes Widgets. The Factory class needs to muck about with the internals, because, it is the Factory. Both are implemented in the same file and are, by design and desire and nature, tightly coupled classes -- in fact, Widget is really just an output type from factory.

In C++, make the Factory a friend of Widget class.

In C#, what can we do? The only decent solution that has occurred to me is to invent an interface, IWidget, which only exposes the public methods, and have the Factory return IWidget interfaces.

This involves a fair amount of tedium - exposing all the naturally public properties again in the interface.

David Crawshaw project(sqlitejdbc-v056.jar) seems out of date and last update was Jun 20, 2009, source here

I would recomend Xerials fork of Crawshaw sqlite wrapper. I replaced sqlitejdbc-v056.jar with Xerials sqlite-jdbc-3.7.2.jar file without any problem.

Uses same syntax as in Bernie's answer and is much faster and with latest sqlite library.

What is different from Zentus's SQLite JDBC?

The original Zentus's SQLite JDBC driver http://www.zentus.com/sqlitejdbc/ itself is an excellent utility for using SQLite databases from Java language, and our SQLiteJDBC library also relies on its implementation. However, its pure-java version, which totally translates c/c++ codes of SQLite into Java, is significantly slower compared to its native version, which uses SQLite binaries compiled for each OS (win, mac, linux).

To use the native version of sqlite-jdbc, user had to set a path to the native codes (dll, jnilib, so files, which are JNDI C programs) by using command-line arguments, e.g., -Djava.library.path=(path to the dll, jnilib, etc.), or -Dorg.sqlite.lib.path, etc. This process was error-prone and bothersome to tell every user to set these variables. Our SQLiteJDBC library completely does away these inconveniences.

Another difference is that we are keeping this SQLiteJDBC libray up-to-date to the newest version of SQLite engine, because we are one of the hottest users of this library. For example, SQLite JDBC is a core component of UTGB (University of Tokyo Genome Browser) Toolkit, which is our utility to create personalized genome browsers.

EDIT : As usual when you update something, there will be problems in some obscure place in your code(happened to me). Test test test =)

A few snippets from the HTML5 spec: http://w3c.github.io/html/semantics-scripting.html#element-attrdef-script-async

The defer and async attributes must not be specified if the src attribute is not present.

There are three possible modes that can be selected using these attributes [async and defer]. If the async attribute is present, then the script will be executed asynchronously, as soon as it is available. If the async attribute is not present but the defer attribute is present, then the script is executed when the page has finished parsing. If neither attribute is present, then the script is fetched and executed immediately, before the user agent continues parsing the page.

The exact processing details for these attributes are, for mostly historical reasons, somewhat non-trivial, involving a number of aspects of HTML. The implementation requirements are therefore by necessity scattered throughout the specification. The algorithms below (in this section) describe the core of this processing, but these algorithms reference and are referenced by the parsing rules for script start and end tags in HTML, in foreign content, and in XML, the rules for the document.write() method, the handling of scripting, etc.

If the element has a src attribute, and the element has a defer attribute, and the element has been flagged as "parser-inserted", and the element does not have an async attribute:

The element must be added to the end of the list of scripts that will execute when the document has finished parsing associated with the Document of the parser that created the element.

There is a somehow recommended directory structure mentioned at https://docs.spring.io/spring-boot/docs/current/reference/html/using-boot-structuring-your-code.html

You can create a api folder and put your controllers there.

If you have some configuration beans, put them in a separate package too.

Ok so I took Joshoun code and made it generic. I am not sure if I should implement singleton pattern on SynchronousPost class. Maybe someone more knowledgeble can help.

Implementation

FileCategory x = new FileCategory { CategoryName = "Some Bs"};
SynchronousPost<FileCategory>test= new SynchronousPost<FileCategory>();
test.PostEntity(x, "/api/ApiFileCategories"); 

Generic Class here. You can pass any type

 public class SynchronousPost<T>where T :class
    {
        public SynchronousPost()
        {
            Client = new WebClient { UseDefaultCredentials = true };
        }

        public void PostEntity(T PostThis,string ApiControllerName)//The ApiController name should be "/api/MyName/"
        {
            //this just determines the root url. 
            Client.BaseAddress = string.Format(
         (
            System.Web.HttpContext.Current.Request.Url.Port != 80) ? "{0}://{1}:{2}" : "{0}://{1}",
            System.Web.HttpContext.Current.Request.Url.Scheme,
            System.Web.HttpContext.Current.Request.Url.Host,
            System.Web.HttpContext.Current.Request.Url.Port
           );
            Client.Headers.Add(HttpRequestHeader.ContentType, "application/json;charset=utf-8");
            Client.UploadData(
                                 ApiControllerName, "Post", 
                                 Encoding.UTF8.GetBytes
                                 (
                                    JsonConvert.SerializeObject(PostThis)
                                 )
                             );  
        }
        private WebClient Client  { get; set; }
    }

My Api classs looks like this, if you are curious

public class ApiFileCategoriesController : ApiBaseController
{
    public ApiFileCategoriesController(IMshIntranetUnitOfWork unitOfWork)
    {
        UnitOfWork = unitOfWork;
    }

    public IEnumerable<FileCategory> GetFiles()
    {
        return UnitOfWork.FileCategories.GetAll().OrderBy(x=>x.CategoryName);
    }
    public FileCategory GetFile(int id)
    {
        return UnitOfWork.FileCategories.GetById(id);
    }
    //Post api/ApileFileCategories

    public HttpResponseMessage Post(FileCategory fileCategory)
    {
        UnitOfWork.FileCategories.Add(fileCategory);
        UnitOfWork.Commit(); 
        return new HttpResponseMessage();
    }
}

I am using ninject, and repo pattern with unit of work. Anyways, the generic class above really helps.

Use get(0) instead of html(). In other words, replace

doc.fromHTML($('#htmlTableId').html(), 15, 15, {
    'width': 170,'elementHandlers': specialElementHandlers
});

with

doc.fromHTML($('#htmlTableId').get(0), 15, 15, {
    'width': 170,'elementHandlers': specialElementHandlers
});

The only workable solution is to restore the .bak file. The contents and the structure of those files are not documented and therefore, there's really no way (other than an awful hack) to get this to work - definitely not worth your time and the effort!

The only tool I'm aware of that can make sense of .bak files without restoring them is Red-Gate SQL Compare Professional (and the accompanying SQL Data Compare) which allow you to compare your database structure against the contents of a .bak file. Red-Gate tools are absolutely marvelous - highly recommended and well worth every penny they cost!

And I just checked their web site - it does seem that you can indeed restore a single table from out of a .bak file with SQL Compare Pro ! :-)

Just to add that there should be no space between the selector and the opening bracket.

td[someclass] 

will work. But

td [someclass] 

will not.

Another example of a weird problem and its solution:

This:

target_link_libraries(
    ${PROJECT_NAME}
    ${Poco_LIBRARIES}
    ${Poco_Foundation_LIBRARY}
    ${Poco_Net_LIBRARY}
    ${Poco_Util_LIBRARY}
    )

gives: make[3]: *** No rule to make target '/usr/lib/libPocoFoundationd.so', needed by '../hello_poco/bin/mac/HelloPoco'. Stop.

But if I remove Poco_LIBRARIES it works:

target_link_libraries(
    ${PROJECT_NAME}
    ${Poco_Foundation_LIBRARY}
    ${Poco_Net_LIBRARY}
    ${Poco_Util_LIBRARY}
    )

I'm using clang8 on Mac and clang 3.9 on Linux The problem only occurs on Linux but works on Mac!

I forgot to mention: Poco_LIBRARIES was wrong - it was not set by cmake/find_package!

There is no simple command available to find out the largest files/directories on a Linux/UNIX/BSD filesystem. However, combination of following three commands (using pipes) you can easily find out list of largest files:

# du -a /var | sort -n -r | head -n 10

If you want more human readable output try:

$ cd /path/to/some/var
$ du -hsx * | sort -rh | head -10

Where,

• Var is the directory you wan to search
• du command -h option : display sizes in human readable format (e.g., 1K, 234M, 2G).
• du command -s option : show only a total for each argument (summary).
• du command -x option : skip directories on different file systems.
• sort command -r option : reverse the result of comparisons.
• sort command -h option : compare human readable numbers. This is GNU sort specific option only.
• head command -10 OR -n 10 option : show the first 10 lines.

You just need to clear the table and call the function that generates the filling of the table.

ButtonRefresh.setOnAction((event) -> {
            tacheTable.getItems().clear();
            PopulateTable();
        });

Both are equivalent. Take a look at the following:

int[] array;

// is equivalent to

int array[];

int var, array[];

// is equivalent to

int var;
int[] array;

int[] array1, array2[];

// is equivalent to

int[] array1;
int[][] array2;

public static int[] getArray()
{
    // ..
}

// is equivalent to

public static int getArray()[]
{
    // ..
}

In order to find out which user you need to give permission to do the restore process, you can follow the following steps:

You need to go to your server where SQL Server is installed. Find SQL Server Configuration Manager

Next, you need to go to "SQL Server Services"

Under your SQL Server (MSSQLSERVER) instance there will be an account with column "Logon As", in my case it is NT Service\MSSQLSERVER.

That is the account which you need to add under Security tab of your source .bak location and give that user the "Read" permissions so that the backup file can be read.

Let's say your backup file is present at "D:\Shared" folder, then you need to give permissions like this:

Try

RewriteEngine On 
RewriteCond %{REQUEST_FILENAME} !-d 
RewriteCond %{REQUEST_FILENAME} !-f 
RewriteCond %{REQUEST_FILENAME}.php -f 
RewriteRule ^(.*)$ $1.php [L] 

If you are using the terminal ( i am using ubuntu ) , then just use the combination of CTRL+l from keyboard to clear the python script, even it clears the terminal script...

change onClick to onClick="changeDivContent(this)" and try

function changeDivContent(btn) {
  content.innerHTML = btn.value
}

function changeDivContent(btn) {_x000D_
  content.innerHTML = btn.value_x000D_
}

<input type="radio" name="radiobutton" value="A" onClick="changeDivContent(this)">_x000D_
<input type="radio" name="radiobutton" value="B" onClick="changeDivContent(this)">_x000D_
_x000D_
<div id="content"></div>

To refresh menu from Fragment simply call:

In SQL, a comparison between a null value and any other value (including another null) using a comparison operator (eg =, !=, <, etc) will result in a null, which is considered as false for the purposes of a where clause (strictly speaking, it's "not true", rather than "false", but the effect is the same).

The reasoning is that a null means "unknown", so the result of any comparison to a null is also "unknown". So you'll get no hit on rows by coding where my_column = null.

SQL provides the special syntax for testing if a column is null, via is null and is not null, which is a special condition to test for a null (or not a null).

Here's some SQL showing a variety of conditions and and their effect as per above.

create table t (x int, y int);
insert into t values (null, null), (null, 1), (1, 1);

select 'x = null' as test , x, y from t where x = null
union all
select 'x != null', x, y from t where x != null
union all
select 'not (x = null)', x, y from t where not (x = null)
union all
select 'x = y', x, y from t where x = y
union all
select 'not (x = y)', x, y from t where not (x = y);

returns only 1 row (as expected):

TEST    X   Y
x = y   1   1

No problems with my terminal. The above answers helped me looking in the right directions but it didn't work for me until I added 'ignore':

fix_encoding = lambda s: s.decode('utf8', 'ignore')

As indicated in the comment below, this may lead to undesired results. OTOH it also may just do the trick well enough to get things working and you don't care about losing some characters.

@denver_citizen and @Peter Szanto's answers didn't quite work for me, but I modified them to account for:

1. Composite Keys
2. On Delete and On Update actions
3. Checking the index when re-adding
4. Schemas other than dbo
5. Multiple tables at once

I hope that you will find helpfull the following trick.

You can bind both the events

combobox.SelectionChanged += OnSelectionChanged;
combobox.DropDownOpened += OnDropDownOpened;

And force selected item to null inside the OnDropDownOpened

private void OnDropDownOpened(object sender, EventArgs e)
{
    combobox.SelectedItem = null;
}

And do what you need with the item inside the OnSelectionChanged. The OnSelectionChanged will be raised every time you will open the combobox, but you can check if SelectedItem is null inside the method and skip the command

private void OnSelectionChanged(object sender, SelectionChangedEventArgs e)
    {
        if (combobox.SelectedItem != null)
        {
           //Do something with the selected item
        }
    }

Here is a very short way to do it

function arrEquals(arr1, arr2){
     return arr1.length == arr2.length && 
     arr1.filter(elt=>arr1.filter(e=>e===elt).length == arr2.filter(e=>e===elt).length).length == arr1.length
}

Not sure if you can do that with multi-line code, but multi-line variables can be done:

Multiline strings in VB.NET

Here is the relevant chunk:

I figured out how to use both <![CDATA[ along with <%= for variables, which allows you to code without worry.

You basically have to terminate the CDATA tags before the VB variable and then re-add it after so the CDATA does not capture the VB code. You need to wrap the entire code block in a tag because you will you have multiple CDATA blocks.

Dim script As String = <code><![CDATA[
  <script type="text/javascript">
    var URL = ']]><%= domain %><![CDATA[/mypage.html';
  </script>]]>
</code>.value

Have you tried using the stream_context_set_option() method ?

$context = stream_context_create();
$result = stream_context_set_option($context, 'ssl', 'local_cert', '/etc/ssl/certs/cacert.pem');
$fp = fsockopen($host, $port, $errno, $errstr, 20, $context);

In addition, try file_get_contents() for the pem file, to make sure you have permissions to access it, and make sure the host name matches the certificate.

Take a look at this post, it seems like for later versions of Python, certificates are not pre installed which seems to cause this error. You should be able to run the following command to install the certifi package: /Applications/Python\ 3.6/Install\ Certificates.command

Post 1: urllib and "SSL: CERTIFICATE_VERIFY_FAILED" Error

Post 2: Airbrake error: urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate

Yes, you can switch on the name...

switch (obj.GetType().Name)
{
    case "TextBox":...
}

Oracle 11g provides a PIVOT operation that does what you want.

Oracle 11g solution

select * from
(select id, k, v from _kv) 
pivot(max(v) for k in ('name', 'age', 'gender', 'status')

(Note: I do not have a copy of 11g to test this on so I have not verified its functionality)

I obtained this solution from: http://orafaq.com/wiki/PIVOT

EDIT -- pivot xml option (also Oracle 11g)
Apparently there is also a pivot xml option for when you do not know all the possible column headings that you may need. (see the XML TYPE section near the bottom of the page located at http://www.oracle.com/technetwork/articles/sql/11g-pivot-097235.html)

select * from
(select id, k, v from _kv) 
pivot xml (max(v)
for k in (any) )

(Note: As before I do not have a copy of 11g to test this on so I have not verified its functionality)

Edit2: Changed v in the pivot and pivot xml statements to max(v) since it is supposed to be aggregated as mentioned in one of the comments. I also added the in clause which is not optional for pivot. Of course, having to specify the values in the in clause defeats the goal of having a completely dynamic pivot/crosstab query as was the desire of this question's poster.

My simple answer.

def get_files_tree(src="src_path"):
    req_files = []
    for r, d, files in os.walk(src):
        for file in files:
            src_file = os.path.join(r, file)
            src_file = src_file.replace('\\', '/')
            if src_file.endswith('.db'):
                continue
            req_files.append(src_file)

    return req_files
def copy_tree_force(src_path="",dest_path=""):
    """
    make sure that all the paths has correct slash characters.
    """
    for cf in get_files_tree(src=src_path):
        df= cf.replace(src_path, dest_path)
        if not os.path.exists(os.path.dirname(df)):
            os.makedirs(os.path.dirname(df))
        shutil.copy2(cf, df)

You can also test them as a couple.

if (i,ii)==(5,10):
    print "i is 5 and ii is 10"

In DJango 3.0 the default value of a BooleanField in model.py is set like this:

class model_name(models.Model):
example_name = models.BooleanField(default=False)

You can use pd.Timestamp to perform a query and a local reference

import pandas as pd
import numpy as np

df = pd.DataFrame()
ts = pd.Timestamp

df['date'] = np.array(np.arange(10) + datetime.now().timestamp(), dtype='M8[s]')

print(df)
print(df.query('date > @ts("20190515T071320")')

with the output

                 date
0 2019-05-15 07:13:16
1 2019-05-15 07:13:17
2 2019-05-15 07:13:18
3 2019-05-15 07:13:19
4 2019-05-15 07:13:20
5 2019-05-15 07:13:21
6 2019-05-15 07:13:22
7 2019-05-15 07:13:23
8 2019-05-15 07:13:24
9 2019-05-15 07:13:25


                 date
5 2019-05-15 07:13:21
6 2019-05-15 07:13:22
7 2019-05-15 07:13:23
8 2019-05-15 07:13:24
9 2019-05-15 07:13:25

Have a look at the pandas documentation for DataFrame.query, specifically the mention about the local variabile referenced udsing @ prefix. In this case we reference pd.Timestamp using the local alias ts to be able to supply a timestamp string

There are plenty available. Try using Modal windows of Jquery or DHTML would do good. Put the content in your div or Change your content in div dynamically and show it to the user. It won't be a popup but a modal window.
Jquery's Thickbox would clear your problem.

You can specify the colClasse for only one columns.

So in your example you should use:

data <- read.csv('test.csv', colClasses=c("time"="character"))

It's a way to enforce a set of invariants of the abstract class. That is, no matter what the subclass does, you want to make sure some things are always true of the base class... example:

abstract class Foo
{
    public DateTime TimeCreated {get; private set;}

    protected Foo()
    {
         this.TimeCreated = DateTime.Now;
    }
}

abstract class Bar : Foo
{
    public Bar() : base() //Bar's constructor's must call Foo's parameterless constructor.
    { }
}

Don't think of a constructor as the dual of the new operator. The constructor's only purpose is to ensure that you have an object in a valid state before you start using it. It just happens to be that we usually call it through a new operator.

for Oracle Database 10g users:

alter table mytable modify(mycolumn null);

You get "ORA-01735: invalid ALTER TABLE option" when you try otherwise

ALTER TABLE mytable ALTER COLUMN mycolumn DROP NOT NULL;

np.array() is even more powerful than what unutbu said above. You also could use it to convert a list of np arrays to a higher dimention array, the following is a simple example:

aArray=np.array([1,1,1])

bArray=np.array([2,2,2])

aList=[aArray, bArray]

xArray=np.array(aList)

xArray's shape is (2,3), it's a standard np array. This operation avoids a loop programming.

You can use flatMap to flatten the internal lists (after converting them to Streams) into a single Stream, and then collect the result into a list:

List<List<Object>> list = ...
List<Object> flat = 
    list.stream()
        .flatMap(List::stream)
        .collect(Collectors.toList());

DataTable.Clone() should do the trick.

DataTable newTable = originalTable.Clone();

One option is to put the subquery in a LEFT JOIN:

select sum ( t.graduates ) - t1.summedGraduates 
from table as t
    left join 
     ( 
        select sum ( graduates ) summedGraduates, id
        from table  
        where group_code not in ('total', 'others' )
        group by id 
    ) t1 on t.id = t1.id
where t.group_code = 'total'
group by t1.summedGraduates 

Perhaps a better option would be to use SUM with CASE:

select sum(case when group_code = 'total' then graduates end) -
    sum(case when group_code not in ('total','others') then graduates end)
from yourtable

I would like to add that you should make sure that the generated config.yml file when doing ruby dk.rb init contains the path to the ruby installation you want to use DevKit with. In my case, I had the Heroku Toolbelt installed on my system, which provided its own ruby installation, located at a different place. The config.yml file used that particular installation, and that's not what I wanted. I had to manually edit the file to point it to the correct one, then continue with ruby dk.rb review, etc.

You can call Number object and then call toString().

Number.call(null, n).toString()

You may use this trick for another javascript native objects.

HTML css works fine if body tag does nothing you can write as well

<body scroll="no" style="overflow: hidden">

In this case overriding should be on the body tag, it is easier to control but sometimes gives headaches.

Try this one:

System.DateTime.Now.ToString("yyyy/MM/dd HH:mm:ss")

On the windows platform, I met that problem too The solution for me is just add

C:\Windows\System32

to the PATH

and restart the computer.

"s" is not a "char*", it's a "char[4]". And so, "&s" is not a "char**", but actually "a pointer to an array of 4 characater". Your compiler may treat "&s" as if you had written "&s[0]", which is roughly the same thing, but is a "char*".

When you write "char** p = &s;" you are trying to say "I want p to be set to the address of the thing which currently points to "asd". But currently there is nothing which points to "asd". There is just an array which holds "asd";

char s[] = "asd";
char *p = &s[0];  // alternately you could use the shorthand char*p = s;
char **pp = &p;

The first thing you need to do is use the decimal type instead of float for the prices. Using float is absolutely unacceptable for that because it cannot accurately represent most decimal fractions.

Once you have done that, Decimal.Round() can be used to round to 2 places.

No, you can't do this using Javascript alone. Client-side Javascript cannot read the contents of a directory the way I think you're asking about.

However, if you're able to add an index page to (or configure your web server to show an index page for) the images directory and you're serving the Javascript from the same server then you could make an AJAX call to fetch the index and then parse it.

i.e.

1) Enable indexes in Apache for the relevant directory on yoursite.com:

http://www.cyberciti.biz/faq/enabling-apache-file-directory-indexing/

2) Then fetch / parse it with jQuery. You'll have to work out how best to scrape the page and there's almost certainly a more efficient way of fetching the entire list, but an example:

$.ajax({
  url: "http://yoursite.com/images/",
  success: function(data){
     $(data).find("td > a").each(function(){
        // will loop through 
        alert("Found a file: " + $(this).attr("href"));
     });
  }
});

The is operator in Python probably doesn't do what you expect. Instead of this:

    if numpy.array_equal(tmp,universe_array) is True:
        break

I would write it like this:

    if numpy.array_equal(tmp,universe_array):
        break

The is operator tests object identity, which is something quite different from equality.

SimpleDateFormat sdf = new SimpleDateFormat("dd-MM-yyyy");

return sdf.parse(dateStr);

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
SimpleDateFormat newSdf = new SimpleDateFormat("dd-MM-yyyy");
Date temp = sdf.parse(dateStr);
return newSdf.format(temp);

I have encountered this error on "an empty branch" on my local gitlab server. Some people mentioned that "you can not push for the first time on an empty branch". I tried to create a simple README file on the gitlab via my browser. Then everything fixed amazingly and the problem sorted out!! I mention that I was the master and the branch was not protected.

1. Open "Turn windows features on or off" by: WinKey+ R => "optionalfeatures" => OK

2. Enable those features under "Application Development Features"

Tested on Win 10 - But probably will work on other windows versions as well.

iframes are used a lot to include complete pages. When those pages are hosted on another domain you get problems with cross side scripting and stuff. There are ways to fix this.

Frames were used to divide your page into multiple parts (for example, a navigation menu on the left). Using them is no longer recommended.

When you declare

public static <T> void foo(List<T>... bar) the compiler converts it to

public static <T> void foo(List<T>[] bar) then to

public static void foo(List[] bar)

The danger then arises that you'll mistakenly assign incorrect values into the list and the compiler will not trigger any error. For example, if T is a String then the following code will compile without error but will fail at runtime:

// First, strip away the array type (arrays allow this kind of upcasting)
Object[] objectArray = bar;

// Next, insert an element with an incorrect type into the array
objectArray[0] = Arrays.asList(new Integer(42));

// Finally, try accessing the original array. A runtime error will occur
// (ClassCastException due to a casting from Integer to String)
T firstElement = bar[0].get(0);

If you reviewed the method to ensure that it doesn't contain such vulnerabilities then you can annotate it with @SafeVarargs to suppress the warning. For interfaces, use @SuppressWarnings("unchecked").

If you get this error message:

Varargs method could cause heap pollution from non-reifiable varargs parameter

and you are sure that your usage is safe then you should use @SuppressWarnings("varargs") instead. See Is @SafeVarargs an appropriate annotation for this method? and https://stackoverflow.com/a/14252221/14731 for a nice explanation of this second kind of error.

I think init_js should use declare instead of local!

function scan3() {
    declare -n outvar=$1    # -n makes it a nameref.
    local nl=$'\x0a'
    outvar="output${nl}${nl}"  # two total. quotes preserve newlines
}

You can use in():

select * 
from table
where id in (multiple row query)

or use a join:

select distinct t.* 
from source_of_id_table s
join table t on t.id = s.t_id
where <conditions for source_of_id_table>

The join is never a worse choice for performance, and depending on the exact situation and the database you're using, can give much better performance.

The formats and codecs supported by your build of ffmpeg can vary due the version, how it was compiled, and if any external libraries, such as libx264, were supported during compilation.

Formats (muxers and demuxers):

List all formats:

ffmpeg -formats

Display options specific to, and information about, a particular muxer:

ffmpeg -h muxer=matroska

Display options specific to, and information about, a particular demuxer:

ffmpeg -h demuxer=gif

Codecs (encoders and decoders):

List all codecs:

ffmpeg -codecs

List all encoders:

ffmpeg -encoders

List all decoders:

ffmpeg -decoders

Display options specific to, and information about, a particular encoder:

ffmpeg -h encoder=mpeg4

Display options specific to, and information about, a particular decoder:

ffmpeg -h decoder=aac

Reading the results

There is a key near the top of the output that describes each letter that precedes the name of the format, encoder, decoder, or codec:

$ ffmpeg -encoders
[…]
Encoders:
 V..... = Video
 A..... = Audio
 S..... = Subtitle
 .F.... = Frame-level multithreading
 ..S... = Slice-level multithreading
 ...X.. = Codec is experimental
 ....B. = Supports draw_horiz_band
 .....D = Supports direct rendering method 1
 ------
[…]
 V.S... mpeg4                MPEG-4 part 2

In this example V.S... indicates that the encoder mpeg4 is a Video encoder and supports Slice-level multithreading.

Maybe not so Pythonic, but somewhat more self-explanatory. It returns the position of the word looked in the original string.

def retrieve_occurences(sequence, word, result, base_counter):
     indx = sequence.find(word)
     if indx == -1:
         return result
     result.append(indx + base_counter)
     base_counter += indx + len(word)
     return retrieve_occurences(sequence[indx + len(word):], word, result, base_counter)

If BranchA has not been pushed to a remote then you can reorder the commits using rebase and then simply merge. It's preferable to use merge over rebase when possible because it doesn't create duplicate commits.

git checkout BranchA
git rebase -i HEAD~113
... reorder the commits so the 10 you want are first ...
git checkout BranchB
git merge [the 10th commit]

You didn't specify how the order is determined, but this will give you a rank value in MySQL:

SELECT t.*,
       @rownum := @rownum +1 AS rank
  FROM TBL_FOO t
  JOIN (SELECT @rownum := 0) r
 WHERE t.name = 'sarmen'

Then you can pick out what rows you want, based on the rank value.

For saving the original stdout and stderr you can use:

exec [fd number]<&1 
exec [fd number]<&2

For example, the following code will print "walla1" and "walla2" to the log file (a.txt), "walla3" to stdout, "walla4" to stderr.

#!/bin/bash

exec 5<&1
exec 6<&2

If you want to force the issue, you can do:

git reset --hard c14809fafb08b9e96ff2879999ba8c807d10fb07

send you back to how your git clone looked like at the time of the checkin

This is a prompt to create a bunch of object, such as sp_help_diagram (?), that do not exist.

This should have nothing to do with the owner of the db.

Here is simple Scala version in Linear O(n) time:

def getProductEff(in:Seq[Int]):Seq[Int] = {

   //create a list which has product of every element to the left of this element
   val fromLeft = in.foldLeft((1, Seq.empty[Int]))((ac, i) => (i * ac._1, ac._2 :+ ac._1))._2

   //create a list which has product of every element to the right of this element, which is the same as the previous step but in reverse
   val fromRight = in.reverse.foldLeft((1,Seq.empty[Int]))((ac,i) => (i * ac._1,ac._2 :+ ac._1))._2.reverse

   //merge the two list by product at index
   in.indices.map(i => fromLeft(i) * fromRight(i))

}

This works because essentially the answer is an array which has product of all elements to the left and to the right.

May you should try creating a temp string object and then add to existing item string. Something like this.

for(int k=0; k<bufferPos; k++){
      item += String(buffer[k]);
      }

You're missing a semicolon: double b = a * Math.PI;

The quick answer is :

No, you are not allowed to do that. Because that is what Date use for.

From javadoc of Date :

The class Date represents a specific instant in time, with millisecond precision.

However, since this class is simply a data object. It dose not care about how we describe it. When we see a date 2012/01/01 12:05:10.321, we can say it is 2012/01/01, this is what you need. There are many ways to do this.

Example 1 : by manipulating string

Input string : 2012/01/20 12:05:10.321

Desired output string : 2012/01/20

Since the yyyy/MM/dd are exactly what we need, we can simply manipulate the string to get the result.

String input = "2012/01/20 12:05:10.321";
String output = input.substring(0, 10);  // Output : 2012/01/20

Example 2 : by SimpleDateFormat

Input string : 2012/01/20 12:05:10.321

Desired output string : 01/20/2012

In this case we want a different format.

String input = "2012/01/20 12:05:10.321";
DateFormat inputFormatter = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss.SSS");
Date date = inputFormatter.parse(input);

DateFormat outputFormatter = new SimpleDateFormat("MM/dd/yyyy");
String output = outputFormatter.format(date); // Output : 01/20/2012

For usage of SimpleDateFormat, check SimpleDateFormat JavaDoc.

So I did some more research into this and it turns out there isn't anything specific for this. I got excited when I found list.index(value), it returns the index of a specified item, but there isn't anything for getting the value at a specific index. So if you don't want to use the safe_list_get solution which I think is pretty good. Here are some 1 liner if statements that can get the job done for you depending on the scenario:

>>> x = [1, 2, 3]
>>> el = x[4] if len(x) > 4 else 'No'
>>> el
'No'

You can also use None instead of 'No', which makes more sense.:

>>> x = [1, 2, 3]
>>> i = 2
>>> el_i = x[i] if len(x) == i+1 else None

Also if you want to just get the first or last item in the list, this works

end_el = x[-1] if x else None

You can also make these into functions but I still liked the IndexError exception solution. I experimented with a dummied down version of the safe_list_get solution and made it a bit simpler (no default):

def list_get(l, i):
    try:
        return l[i]
    except IndexError:
        return None

Haven't benchmarked to see what is fastest.

Another solution:

if (view == null) {
    view = inflater.inflate(R.layout.nearbyplaces, container, false);
}

That's it, if not null you don't need to reinitialize it removing from parent is unnecessary step.

I do get this error when I do not set the Authentication header or I set wrong credentials.

With Swift 3 and Swift 4, String has a method called data(using:allowLossyConversion:). data(using:allowLossyConversion:) has the following declaration:

func data(using encoding: String.Encoding, allowLossyConversion: Bool = default) -> Data?

Returns a Data containing a representation of the String encoded using a given encoding.

With Swift 4, String's data(using:allowLossyConversion:) can be used in conjunction with JSONDecoder's decode(_:from:) in order to deserialize a JSON string into a dictionary.

Furthermore, with Swift 3 and Swift 4, String's data(using:allowLossyConversion:) can also be used in conjunction with JSONSerialization's json?Object(with:?options:?) in order to deserialize a JSON string into a dictionary.

#1. Swift 4 solution

With Swift 4, JSONDecoder has a method called decode(_:from:). decode(_:from:) has the following declaration:

func decode<T>(_ type: T.Type, from data: Data) throws -> T where T : Decodable

Decodes a top-level value of the given type from the given JSON representation.

The Playground code below shows how to use data(using:allowLossyConversion:) and decode(_:from:) in order to get a Dictionary from a JSON formatted String:

let jsonString = """
{"password" : "1234",  "user" : "andreas"}
"""

if let data = jsonString.data(using: String.Encoding.utf8) {
    do {
        let decoder = JSONDecoder()
        let jsonDictionary = try decoder.decode(Dictionary<String, String>.self, from: data)
        print(jsonDictionary) // prints: ["user": "andreas", "password": "1234"]
    } catch {
        // Handle error
        print(error)
    }
}

#2. Swift 3 and Swift 4 solution

With Swift 3 and Swift 4, JSONSerialization has a method called json?Object(with:?options:?). json?Object(with:?options:?) has the following declaration:

class func jsonObject(with data: Data, options opt: JSONSerialization.ReadingOptions = []) throws -> Any

Returns a Foundation object from given JSON data.

The Playground code below shows how to use data(using:allowLossyConversion:) and json?Object(with:?options:?) in order to get a Dictionary from a JSON formatted String:

import Foundation

let jsonString = "{\"password\" : \"1234\",  \"user\" : \"andreas\"}"

if let data = jsonString.data(using: String.Encoding.utf8) {
    do {
        let jsonDictionary = try JSONSerialization.jsonObject(with: data, options: []) as? [String : String]
        print(String(describing: jsonDictionary)) // prints: Optional(["user": "andreas", "password": "1234"])
    } catch {
        // Handle error
        print(error)
    }
}

you could possibly add in the port for non port 80/SSL?

something like:

if (HttpContext.Current.Request.ServerVariables["SERVER_PORT"] != null && HttpContext.Current.Request.ServerVariables["SERVER_PORT"].ToString() != "80" && HttpContext.Current.Request.ServerVariables["SERVER_PORT"].ToString() != "443")
            {
                port = String.Concat(":", HttpContext.Current.Request.ServerVariables["SERVER_PORT"].ToString());
            }

and use that in the final result?

I got the following for me:

formSubmit('#login-form', '/api/user/login', '/members/');

where

function formSubmit(form, url, target) {
    $(form).submit(function(event) {
        $.post(url, $(form).serialize())
            .done(function(res) {
                if (res.success) {
                    window.location = target;
                }
                else {
                    alert(res.error);
                }
            })
            .fail(function(res) {
                alert("Server Error: " + res.status + " " + res.statusText);

            })
        event.preventDefault();
    });
}

This assumes the post to 'url' returns an ajax in the form of {success: false, error:'my Error to display'}

You can vary this as you like. Feel free to use that snippet.

Here's one way to do it—there are many others:

bool b[4];
int v = 7;  // number to dissect

for (int j = 0;  j < 4;  ++j)
   b [j] =  0 != (v & (1 << j));

It is hard to understand why use of a loop is not desired, but it is easy enough to unroll the loop:

bool b[4];
int v = 7;  // number to dissect

b [0] =  0 != (v & (1 << 0));
b [1] =  0 != (v & (1 << 1));
b [2] =  0 != (v & (1 << 2));
b [3] =  0 != (v & (1 << 3));

Or evaluating constant expressions in the last four statements:

b [0] =  0 != (v & 1);
b [1] =  0 != (v & 2);
b [2] =  0 != (v & 4);
b [3] =  0 != (v & 8);

Is the opaque overlay for aesthetic purposes?

If so, you can use:

#overlay {
        position: fixed;
        top: 0;
        right: 0;
        bottom: 0;
        left: 0;
        z-index: 50;
        background: #000;
        pointer-events: none;
        opacity: 0.8;
        color: #fff;
}

'pointer-events: none' will change the overlay behavior so that it can be physically opaque. Of course, this will only work in good browsers.

The following code is useful to refresh image when a button is clicked.

function reloadImage(imageId) {
   imgName = 'vishnu.jpg'; //for example
   imageObject = document.getElementById(imageId);
   imageObject.src = imgName;
}

<img src='vishnu.jpg' id='myimage' />

<input type='button' onclick="reloadImage('myimage')" />

The angular way is shown in the angular docs :)

https://docs.angularjs.org/api/ng/directive/ngReadonly

Here is the example they use:

<body>
    Check me to make text readonly: <input type="checkbox" ng-model="checked"><br/>
    <input type="text" ng-readonly="checked" value="I'm Angular"/>
</body>

Basically the angular way is to create a model object that will hold whether or not the input should be readonly and then set that model object accordingly. The beauty of angular is that most of the time you don't need to do any dom manipulation. You just have angular render the view they way your model is set (let angular do the dom manipulation for you and keep your code clean).

So basically in your case you would want to do something like below or check out this working example.

<button ng-click="isInput1ReadOnly = !isInput1ReadOnly">Click Me</button>
<input type="text" ng-readonly="isInput1ReadOnly" value="Angular Rules!"/>

If you are averse to boost, you can use regular old operator>>, along with std::noskipws:

EDIT: updates after testing.

#include <iostream>
#include <iomanip>
#include <vector>
#include <string>
#include <algorithm>
#include <iterator>
#include <sstream>

void split(const std::string& str, std::vector<std::string>& v) {
  std::stringstream ss(str);
  ss >> std::noskipws;
  std::string field;
  char ws_delim;
  while(1) {
    if( ss >> field )
      v.push_back(field);
    else if (ss.eof())
      break;
    else
      v.push_back(std::string());
    ss.clear();
    ss >> ws_delim;
  }
}

int main() {
  std::vector<std::string> v;
  split("hello world  how are   you", v);
  std::copy(v.begin(), v.end(), std::ostream_iterator<std::string>(std::cout, "-"));
  std::cout << "\n";
}

public static URL getFinalURL(URL url) {
    try {
        HttpURLConnection con = (HttpURLConnection) url.openConnection();
        con.setInstanceFollowRedirects(false);
        con.setRequestProperty("User-Agent", "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/62.0.3202.94 Safari/537.36");
        con.addRequestProperty("Accept-Language", "en-US,en;q=0.8");
        con.addRequestProperty("Referer", "https://www.google.com/");
        con.connect();
        //con.getInputStream();
        int resCode = con.getResponseCode();
        if (resCode == HttpURLConnection.HTTP_SEE_OTHER
                || resCode == HttpURLConnection.HTTP_MOVED_PERM
                || resCode == HttpURLConnection.HTTP_MOVED_TEMP) {
            String Location = con.getHeaderField("Location");
            if (Location.startsWith("/")) {
                Location = url.getProtocol() + "://" + url.getHost() + Location;
            }
            return getFinalURL(new URL(Location));
        }
    } catch (Exception e) {
        System.out.println(e.getMessage());
    }
    return url;
}

To get "User-Agent" and "Referer" by yourself, just go to developer mode of one of your installed browser (E.g. press F12 on Google Chrome). Then go to tab 'Network' and then click on one of the requests. You should see it's details. Just press 'Headers' sub tab (the image below)

It could also be that the button needs to have CausesValidation="false". That worked for me.

No need to do so much works..

var query = from c in obj.tbCourses
        where ...
        select c;

Then you can use:

List<course> list_course= query.ToList<course>();

It works fine for me.

Simple way is to use the EJS template engine for serving .html files. Put this line right next to your view engine setup:

app.engine('html', require('ejs').renderFile);

You can ssh directly from the Terminal on Mac, but you need to use a .PEM key rather than the putty .PPK key. You can use PuttyGen on Windows to convert from .PEM to .PPK, I'm not sure about the other way around though.

You can also convert the key using putty for Mac via port or brew:

sudo port install putty

or

brew install putty

This will also install puttygen. To get puttygen to output a .PEM file:

puttygen privatekey.ppk -O private-openssh -o privatekey.pem

Once you have the key, open a terminal window and:

ssh -i privatekey.pem [email protected]

The private key must have tight security settings otherwise SSH complains. Make sure only the user can read the key.

chmod go-rw privatekey.pem

Best way:

var s = 'String';
var a = [1,2,3];
var o = {key: 'val'};

(s.constructor === String) && console.log('its a string');
(a.constructor === Array) && console.log('its an array');
(o.constructor === Object) && console.log('its an object');
(o.constructor === Number || s.constructor === Boolean) && console.log('this won\'t run');

Each of these has been constructed by its appropriate class function, like "new Object()" etc.

Also, Duck-Typing: "If it looks like a duck, walks like a duck, and smells like a duck - it must be an Array" Meaning, check its properties.

Hope this helps.

Edit; 12/05/2016

Remember, you can always use combinations of approaches too. Here's an example of using an inline map of actions with typeof:

var type = { 'number': Math.sqrt.bind(Math), ... }[ typeof datum ];

Here's a more 'real world' example of using inline-maps:

function is(datum) {
    var isnt = !{ null: true, undefined: true, '': true, false: false, 0: false }[ datum ];
    return !isnt;
}
console.log( is(0), is(false), is(undefined), ... );  // >> true true false

This function would use [ custom ] "type-casting" -- rather, "type-/-value-mapping" -- to figure out if a variable actually "exists". Now you can split that nasty hair between null & 0!

Many times you don't even care about its type. Another way to circumvent typing is combining Duck-Type sets:

this.id = "998";  // use a number or a string-equivalent
function get(id) {
    if (!id || !id.toString) return;
    if (id.toString() === this.id.toString()) http( id || +this.id );
    // if (+id === +this.id) ...;
}

Both Number.prototype and String.prototype have a .toString() method. You just made sure that the string-equivalent of the number was the same, and then you made sure that you passed it into the http function as a Number. In other words, we didn't even care what its type was.

Hope that gives you more to work with :)

Declaration says "this thing exists somewhere":

int foo();       // function
extern int bar;  // variable
struct T
{
   static int baz;  // static member variable
};

Definition says "this thing exists here; make memory for it":

int foo() {}     // function
int bar;         // variable
int T::baz;      // static member variable

Initialisation is optional at the point of definition for objects, and says "here is the initial value for this thing":

int bar = 0;     // variable
int T::baz = 42; // static member variable

Sometimes it's possible at the point of declaration instead:

struct T
{
   static int baz = 42;
};

…but that's getting into more complex features.

if you use window.open(url, '_blank') , it will be blocked(popup blocker) on Chrome,Firefox etc

try this,

$('#myButton').click(function () {
    var redirectWindow = window.open('http://google.com', '_blank');
    redirectWindow.location;
});

You've probably miss-typed something above that bit of code or created your own class called IPAddress. If you're using the .net one, that function should be available.

Have you tried using System.Net.IPAddress just in case?

System.Net.IPAddress ipaddress = System.Net.IPAddress.Parse("127.0.0.1");  //127.0.0.1 as an example

The docs on Microsoft's site have a complete example which works fine on my machine.

I played with this two weeks ago, it's very simple. The only problem is that all the tutorials just talk about saving the image locally. This is how I did it:

1) I set up a form so I can use a POST method.

2) When the user is done drawing, he can click the "Save" button.

3) When the button is clicked I take the image data and put it into a hidden field. After that I submit the form.

document.getElementById('my_hidden').value = canvas.toDataURL('image/png');
document.forms["form1"].submit();

4) When the form is submited I have this small php script:

<?php 
$upload_dir = somehow_get_upload_dir();  //implement this function yourself
$img = $_POST['my_hidden'];
$img = str_replace('data:image/png;base64,', '', $img);
$img = str_replace(' ', '+', $img);
$data = base64_decode($img);
$file = $upload_dir."image_name.png";
$success = file_put_contents($file, $data);
header('Location: '.$_POST['return_url']);
?>

Another simple way using concat:

this.setState({
  arr: this.state.arr.concat('new value')
})

You can update your constraint with a smooth animation if you want, see the chunk of code below:

heightOrWidthConstraint.constant = 100
UIView.animate(withDuration: animateTime, animations:{
self.view.layoutIfNeeded()
})

Python 3 also provide a few simple ways to get it:

$ python3 -c "import os; print(os.cpu_count());"

4

$ python3 -c "import multiprocessing; print(multiprocessing.cpu_count())"

4

Many ways to do this. You could use wildcards in double brackets:

str="/some/directory/file"
if [[ $str == /* ]]; then echo 1; else echo 0; fi

You can use substring expansion:

if [[ ${str:0:1} == "/" ]] ; then echo 1; else echo 0; fi

Or a regex:

if [[ $str =~ ^/ ]]; then echo 1; else echo 0; fi

Original poster - the way you're determining seconds until midnight won't work on a day when daylight savings starts or ends. Here's a chunk of code which shows how to do it... It'll be in number of seconds (an NSTimeInterval); you can do the division/modulus/etc to get down to whatever you need.

No.

JSON is purely meant to be a data description language. As noted on http://www.json.org, it is a "lightweight data-interchange format." - not a programming language.

Per http://en.wikipedia.org/wiki/JSON, the "basic types" supported are:

• Number (integer, real, or floating point)
• String (double-quoted Unicode with backslash escaping)
• Boolean (true and false)
• Array (an ordered sequence of values, comma-separated and enclosed in square brackets)
• Object (collection of key:value pairs, comma-separated and enclosed in curly braces)
• null

string.replaceAll() doesn't correctly work with locale different from predefined. At least in jdk7u10.

This example creates a word dictionary from textfile with windows cyrillic charset CP1251

                                                Charset.forName("CP1251"));
        Set<String> words = new TreeSet<>();
        for (String s: lines ) {
            for (String w : s.split("\\s+")) {
                w = w.replaceAll("\\p{Punct}","");
                words.add(w);

Premise

There is no standard naming of keys in JSON. According to the Objects section of the spec:

The JSON syntax does not impose any restrictions on the strings used as names,...

Which means camelCase or snake_case should work fine.

Driving factors

Imposing a JSON naming convention is very confusing. However, this can easily be figured out if you break it down into components.

1. Programming language for generating JSON

   • Python - snake_case
   • PHP - snake_case
   • Java - camelCase
   • JavaScript - camelCase

2. JSON itself has no standard naming of keys

3. Programming language for parsing JSON

   • Python - snake_case
   • PHP - snake_case
   • Java - camelCase
   • JavaScript - camelCase

Mix-match the components

1. Python » JSON » Python - snake_case - unanimous
2. Python » JSON » PHP - snake_case - unanimous
3. Python » JSON » Java - snake_case - please see the Java problem below
4. Python » JSON » JavaScript - snake_case will make sense; screw the front-end anyways
5. Python » JSON » you do not know - snake_case will make sense; screw the parser anyways
6. PHP » JSON » Python - snake_case - unanimous
7. PHP » JSON » PHP - snake_case - unanimous
8. PHP » JSON » Java - snake_case - please see the Java problem below
9. PHP » JSON » JavaScript - snake_case will make sense; screw the front-end anyways
10. PHP » JSON » you do not know - snake_case will make sense; screw the parser anyways
11. Java » JSON » Python - snake_case - please see the Java problem below
12. Java » JSON » PHP - snake_case - please see the Java problem below
13. Java » JSON » Java - camelCase - unanimous
14. Java » JSON » JavaScript - camelCase - unanimous
15. Java » JSON » you do not know - camelCase will make sense; screw the parser anyways
16. JavaScript » JSON » Python - snake_case will make sense; screw the front-end anyways
17. JavaScript » JSON » PHP - snake_case will make sense; screw the front-end anyways
18. JavaScript » JSON » Java - camelCase - unanimous
19. JavaScript » JSON » JavaScript - camelCase - Original

Java problem

snake_case will still make sense for those with Java entries because the existing JSON libraries for Java are using only methods to access the keys instead of using the standard dot.syntax. This means that it wouldn't hurt that much for Java to access the snake_cased keys in comparison to the other programming language which can do the dot.syntax.

Example for Java's org.json package

JsonObject.getString("snake_cased_key")

Example for Java's com.google.gson package

JsonElement.getAsString("snake_cased_key")

Some actual implementations

• Google Maps JavaScript API - camelCased
• Facebook JavaScript API - snake_cased
• Amazon Web Services - snake_cased & camelCased
• Twitter API - snake_cased
• JSON-LD - camelCased & ProperCamelCased

Conclusions

Choosing the right JSON naming convention for your JSON implementation depends on your technology stack. There are cases where one can use snake_case, camelCase, or any other naming convention.

Another thing to consider is the weight to be put on the JSON-generator vs the JSON-parser and/or the front-end JavaScript. In general, more weight should be put on the JSON-generator side rather than the JSON-parser side. This is because business logic usually resides on the JSON-generator side.

Also, if the JSON-parser side is unknown then you can declare what ever can work for you.

This also works:

I just changed with this.state.color==='white'?'black':'white'.

You can also pick the color from drop-down values and update in place of 'black';

(CodePen)

let suppose you are using xampp and phpmyadmin

you have file name 'ratings.txt' table name 'ratings' and database name 'movies'

if your xampp is installed in "C:\xampp\"

copy your "ratings.txt" file in "C:\xampp\mysql\data\movies" folder

LOAD DATA INFILE 'ratings.txt' INTO TABLE ratings FIELDS TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY '\r\n' IGNORE 1 LINES;

Hope this can help you to omit your error if you are doing this on localhost

Note: This answer predates the Unicode requirement; see the comments.

Just cast it:

CString s;
const TCHAR* x = (LPCTSTR) s;

It works because CString has a cast operator to do exactly this.

Using TCHAR makes your code Unicode-independent; if you're not concerned about Unicode you can simply use char instead of TCHAR.

Objective-C

You have to give the values between 0 and 1.0. So divide the RGB values by 255.

myLabel.textColor= [UIColor colorWithRed:(160/255.0) green:(97/255.0) blue:(5/255.0) alpha:1] ;

Update:

You can also use this macro

#define Rgb2UIColor(r, g, b)  [UIColor colorWithRed:((r) / 255.0) green:((g) / 255.0) blue:((b) / 255.0) alpha:1.0]

and you can call in any of your class like this

 myLabel.textColor = Rgb2UIColor(160, 97, 5);

Swift

This is the normal color synax

myLabel.textColor = UIColor(red: (160/255.0), green: (97/255.0), blue: (5/255.0), alpha: 1.0) 
//The values should be between 0 to 1

Swift is not much friendly with macros

Complex macros are used in C and Objective-C but have no counterpart in Swift. Complex macros are macros that do not define constants, including parenthesized, function-like macros. You use complex macros in C and Objective-C to avoid type-checking constraints or to avoid retyping large amounts of boilerplate code. However, macros can make debugging and refactoring difficult. In Swift, you can use functions and generics to achieve the same results without any compromises. Therefore, the complex macros that are in C and Objective-C source files are not made available to your Swift code.

So we use extension for this

extension UIColor {
    convenience init(_ r: Double,_ g: Double,_ b: Double,_ a: Double) {
        self.init(red: r/255, green: g/255, blue: b/255, alpha: a)
    }
}

You can use it like

myLabel.textColor = UIColor(160.0, 97.0, 5.0, 1.0)

This will do the trick :-

new Date().valueOf() 

As Filburt says; but also note that it's usually better to write

test="not(Count = 'N/A')"

If there's exactly one Count element they mean the same thing, but if there's no Count, or if there are several, then the meanings are different.

Since this answer seems to have become popular, but may be a little cryptic to some readers, let me expand it.

The "=" and "!=" operator in XPath can compare two sets of values. In general, if A and B are sets of values, then "=" returns true if there is any pair of values from A and B that are equal, while "!=" returns true if there is any pair that are unequal.

In the common case where A selects zero-or-one nodes, and B is a constant (say "NA"), this means that not(A = "NA") returns true if A is either absent, or has a value not equal to "NA". By contrast, A != "NA" returns true if A is present and not equal to "NA". Usually you want the "absent" case to be treated as "not equal", which means that not(A = "NA") is the appropriate formulation.

I had to do this and used subprocess.

import subprocess

subprocess.run("python3 script1.py & python3 script2.py", shell=True)

What if the first character is not a letter (but a tab, a space, and a escaped double quote)? We'd better test it until we find a letter! So:

S='  \"ó foo bar\"'
N=0
until [[ ${S:$N:1} =~ [[:alpha:]] ]]; do N=$[$N+1]; done
#F=`echo ${S:$N:1} | tr [:lower:] [:upper:]`
#F=`echo ${S:$N:1} | sed -E -e 's/./\u&/'` #other option
F=`echo ${S:$N:1}
F=`echo ${F} #pure Bash solution to "upper"
echo "$F"${S:(($N+1))} #without garbage
echo '='${S:0:(($N))}"$F"${S:(($N+1))}'=' #garbage preserved

Foo bar
= \"Foo bar=

Mysql documentation says : CREATE SCHEMA is a synonym for CREATE DATABASE as of MySQL 5.0.2.

this all goes back to an ANSI standard for SQL in the mid-80s.

That standard had a "CREATE SCHEMA" command, and it served to introduce multiple name spaces for table and view names. All tables and views were created within a "schema". I do not know whether that version defined some cross-schema access to tables and views, but I assume it did. AFAIR, no product (at least back then) really implemented it, that whole concept was more theory than practice.

OTOH, ISTR this version of the standard did not have the concept of a "user" or a "CREATE USER" command, so there were products that used the concept of a "user" (who then had his own name space for tables and views) to implement their equivalent of "schema".

This is an area where systems differ.

As far as administration is concerned, this should not matter too much, because here you have differences anyway.

As far as you look at application code, you "only" have to care about cases where one application accesses tables from multiple name spaces. AFAIK, all systems support a syntax ".", and for this it should not matter whether the name space is that of a user, a "schema", or a "database".

Like @Ardee said you sharer.php uses data from the meta tags, the Dialog API accepts parameters. Facebook have removed the ability to use the message parameter but you can use the quote parameter which can be useful in a lot of cases e.g.

https://www.facebook.com/dialog/share?
app_id=[your-app-id]
&display=popup
&title=This+is+the+title+parameter
&description=This+is+the+description+parameter
&quote=This+is+the+quote+parameter
&caption=This+is+the+caption+parameter
&href=https%3A%2F%2Fdevelopers.facebook.com%2Fdocs%2F
&redirect_uri=https%3A%2F%2Fwww.[url-in-your-accepted-list].com

Just have to create an app id:

https://developers.facebook.com/docs/apps/register

Then make sure the redirect url domain is listed in the accepted domains for that app.

If the variant is empty then an error will be thrown. The bullet-proof code is the following:

      GetLength = UBound(a) - LBound(a) + 1

cvc-elt.1: Cannot find the declaration of element 'Root'. [7]

Your schemaLocation attribute on the root element should be xsi:schemaLocation, and you need to fix it to use the right namespace.

You should probably change the targetNamespace of the schema and the xmlns of the document to http://myNameSpace.com (since namespaces are supposed to be valid URIs, which Test.Namespace isn't, though urn:Test.Namespace would be ok). Once you do that it should find the schema. The point is that all three of the schema's target namespace, the document's namespace, and the namespace for which you're giving the schema location must be the same.

(though it still won't validate as your <element2> contains an <element3> in the document where the schema expects item)

To avoid exceptions killing your app you should catch those exceptions and treat them the way you wish, defining the behavior for you app on those situations where the id is not found.

begin
  current_user.comments.find(ids)
rescue
  #do something in case of exception found
end

Here's more info on exceptions in ruby.

Add angular cookie lib : angular-cookies.js

You can use $cookies or $cookieStore parameter to the respective controller

Main controller add this inject 'ngCookies':

angular.module("myApp", ['ngCookies']);

Use Cookies in your controller like this way:

 app.controller('checkoutCtrl', function ($scope, $rootScope, $http, $state, $cookies) { 

//store cookies

 $cookies.putObject('final_total_price', $rootScope.fn_pro_per);

//Get cookies

 $cookies.getObject('final_total_price'); }

First create a DataGridTemplateColumn to contain the button:

<DataGridTemplateColumn>
  <DataGridTemplateColumn.CellTemplate> 
    <DataTemplate> 
      <Button Click="ShowHideDetails">Details</Button> 
    </DataTemplate> 
  </DataGridTemplateColumn.CellTemplate> 
</DataGridTemplateColumn>

When the button is clicked, update the containing DataGridRow's DetailsVisibility:

void ShowHideDetails(object sender, RoutedEventArgs e)
{
    for (var vis = sender as Visual; vis != null; vis = VisualTreeHelper.GetParent(vis) as Visual)
    if (vis is DataGridRow)
    {
        var row = (DataGridRow)vis;
        row.DetailsVisibility = 
        row.DetailsVisibility == Visibility.Visible ? Visibility.Collapsed : Visibility.Visible;
        break;
    }
}

If you have multiply rows to delete and you don't want to alter the structure of your tables you can use cursor. 1-You first need to select rows to delete(in a cursor) 2-Then for each row in the cursor you delete the referencing rows and after that delete the row him self.

Ex:

--id is primary key of MainTable
    declare @id int
    set @id = 1
    declare theMain cursor for select FK from MainTable where MainID = @id
    declare @fk_Id int
    open theMain
    fetch next from theMain into @fk_Id
    while @@fetch_status=0
    begin
        --fkid is the foreign key 
        --Must delete from Main Table first then child.
        delete from MainTable where fkid = @fk_Id
        delete from ReferencingTable where fkid = @fk_Id
        fetch next from theMain into @fk_Id
    end
    close theMain
    deallocate theMain

Just found another reason why an element goes blurry when being transformed. I was using transform: translate3d(-5.5px, -18px, 0); to re-position an element once it had been loaded in, however that element became blurry.

I tried all the suggestions above but it turned out that it was due to me using a decimal value for one of the translate values. Whole numbers don't cause the blur, and the further away I went from the whole number the worse the blur became.

i.e. 5.5px blurs the element the most, 5.1px the least.

Just thought I'd chuck this here in case it helps anybody.

I tried sudo apt install nginx-full. You will get all the required packages.

you make the use of the HTML Helper and have

    @using(Html.BeginForm())
    {
        Username: <input type="text" name="username" /> <br />
        Password: <input type="text" name="password" /> <br />
        <input type="submit" value="Login">
        <input type="submit" value="Create Account"/>
    }

or use the Url helper

<form method="post" action="@Url.Action("MyAction", "MyController")" >

Html.BeginForm has several (13) overrides where you can specify more information, for example, a normal use when uploading files is using:

@using(Html.BeginForm("myaction", "mycontroller", FormMethod.Post, new {enctype = "multipart/form-data"}))
{
    < ... >
}

If you don't specify any arguments, the Html.BeginForm() will create a POST form that points to your current controller and current action. As an example, let's say you have a controller called Posts and an action called Delete

public ActionResult Delete(int id)
{
   var model = db.GetPostById(id);
   return View(model);
}

[HttpPost]
public ActionResult Delete(int id)
{
    var model = db.GetPostById(id);
    if(model != null) 
        db.DeletePost(id);

    return RedirectToView("Index");
}

and your html page would be something like:

<h2>Are you sure you want to delete?</h2>
<p>The Post named <strong>@Model.Title</strong> will be deleted.</p>

@using(Html.BeginForm())
{
    <input type="submit" class="btn btn-danger" value="Delete Post"/>
    <text>or</text>
    @Url.ActionLink("go to list", "Index")
}

Use this script instead:

@taskkill/f /im test.exe >nul 2>&1
@pause

What the 2>&1 part actually does, is that it redirects the stderr output to stdout. I will explain it better below:

@taskkill/f /im test.exe >nul 2>&1

Kill the task "test.exe". Redirect stderr to stdout. Then, redirect stdout to nul.

@pause

Show the pause message Press any key to continue . . . until someone presses a key.

NOTE: The @ symbol is hiding the prompt for each command. You can save up to 8 bytes this way.

The shortest version of your script could be:
@taskkill/f /im test.exe >nul 2>&1&pause
The & character is used for redirection the first time, and for separating the commands the second time.
An @ character is not needed twice in a line. This code is just 40 bytes, despite the one you've posted being 49 bytes! I actually saved 9 bytes. For a cleaner code look above.

Simply Refer this URL and download and save required dll files @ this location:

Install virtualenv locally (source of instructions):

Important: Insert the current release (like 16.1.0) for X.X.X.
Check the name of the extracted file and insert it for YYYYY.

$ curl -L -o virtualenv.tar.gz https://github.com/pypa/virtualenv/tarball/X.X.X
$ tar xfz virtualenv.tar.gz
$ python pypa-virtualenv-YYYYY/src/virtualenv.py env

Before you can use or install any package you need to source your virtual Python environment env:

$ source env/bin/activate

To install new python packages (like numpy), use:

(env)$ pip install <package>

$('div[imageId="imageN"]').each(function() {
    // `this` is the div
});

To check for the sole existence of the attribute, no matter which value, you could use ths selector instead: $('div[imageId]')

This will convert Hello World to 48656c6c6f20576f726c64 and print it.

#include <iostream>

    for(unsigned int i=0; i<strlen(hello); i++)
        cout << hex << (int) hello[i];
    return 0;
}

sudo chown -R yourname:www-data cake

then

sudo chmod -R g+s cake

First command changes owner and group.

Second command adds s attribute which will keep new files and directories within cake having the same group permissions.

In your AssemblyVersion in AssemblyInfo.cs file, use a fixed version number instead of specifying *. The * will change the version number on each compilation. That was the issue for this exception in my case.

Java 8 takes more than 1/64th of your physical memory for your Xmssize (Minimum HeapSize) and less than 1/4th of your physical memory for your -Xmxsize (Maximum HeapSize).

You can check the default Java heap size by:

In Windows:

java -XX:+PrintFlagsFinal -version | findstr /i "HeapSize PermSize ThreadStackSize"

In Linux:

java -XX:+PrintFlagsFinal -version | grep -iE 'HeapSize|PermSize|ThreadStackSize'

What system configuration settings influence the default value?

The machine's physical memory & Java version.

Iterate through the loop using the value in a dynamic selector that utilizes the attribute selector.

I just went through the learning process myself. I figured it out, but I agree the documentation is written in a way that was sorta intimidating to me. The big "aha" moment for me was understanding that for browsing, all CKeditor does is open a new window and provide a few parameters in the url. It allows you to add additional parameters but be advised you will need to use encodeURIComponent() on your values.

I call the browser and the uploader with

CKEDITOR.replace( 'body',  
{  
    filebrowserBrowseUrl: 'browse.php?type=Images&dir=' +  
        encodeURIComponent('content/images'),  
    filebrowserUploadUrl: 'upload.php?type=Files&dir=' +  
        encodeURIComponent('content/images')  
}

For the browser, in the open window (browse.php) you use php & js to supply a list of choices and then upon your supplied onclick handler, you call a CKeditor function with two arguments, the url/path to the selected image and CKEditorFuncNum supplied by CKeditor in the url:

function myOnclickHandler(){  
//..    
    window.opener.CKEDITOR.tools.callFunction(<?php echo $_GET['CKEditorFuncNum']; ?>, pathToImage);  
    window.close();
}       

Simarly, the uploader simply calls the url you supply, e.g., upload.php, and again supplies $_GET['CKEditorFuncNum']. The target is an iframe so, after you save the file from $_FILES you pass your feedback to CKeditor as thus:

$funcNum = $_GET['CKEditorFuncNum'];  
exit("<script>window.parent.CKEDITOR.tools.callFunction($funcNum, '$filePath', '$errorMessage');</script>");  

Below is a simple to understand custom browser script. While it does not allow users to navigate around in the server, it does allow you to indicate which directory to pull image files from when calling the browser.

It's all rather basic coding so it should work in all relatively modern browsers.

CKeditor merely opens a new window with the url provided

/*          
    in CKeditor **use encodeURIComponent()** to add dir param to the filebrowserBrowseUrl property

    Replace content/images with directory where your images are housed.
*/          
        CKEDITOR.replace( 'editor1', {  
            filebrowserBrowseUrl: '**browse.php**?type=Images&dir=' + encodeURIComponent('content/images'),  
            filebrowserUploadUrl: 'upload.php?type=Files&dir=' + encodeURIComponent('content/images') 
        });

I couldn't get any of the proposed solutions to work with Bootstrap 4 alpha 6, but the following variation finally got me a centred pagination bar.

CSS override:

.pagination {
  display: inline-flex;
  margin: 0 auto;
}

HTML:

<div class="text-center">
  <ul class="pagination">
    <li><a href="...">...</a></li>
  </ul>
</div>

No other combination of display, margin or class on the wrapping div seemed to work.

The comments above are correct. You're missing the decorators. If you want a generic deserializer you can use this.

public static T DeserializeXMLFileToObject<T>(string XmlFilename)
{
    T returnObject = default(T);
    if (string.IsNullOrEmpty(XmlFilename)) return default(T);

    try
    {
        StreamReader xmlStream = new StreamReader(XmlFilename);
        XmlSerializer serializer = new XmlSerializer(typeof(T));
        returnObject = (T)serializer.Deserialize(xmlStream);
    }
    catch (Exception ex)
    {
        ExceptionLogger.WriteExceptionToConsole(ex, DateTime.Now);
    }
    return returnObject;
}

Then you'd call it like this:

MyObjType MyObj = DeserializeXMLFileToObject<MyObjType>(FilePath);

The response data are in JSON string form. The app must parse that string into JavaScript objects by calling response.json().

  this.http.request('http://thecatapi.com/api/images/get?format=html&results_per_page=10').
  .map(res => res.json())
  .subscribe(data => {
    console.log(data);
  })

There can be a problem with "\00a0" in pseudo-elements because it takes the text-decoration of its defining element, so that, for example, if the defining element is underlined, then the white space of the pseudo-element is also underlined.

The easiest way to deal with this is to define the opacity of the pseudo-element to be zero, eg:

element:before{
  content: "_";
  opacity: 0;
}

At your model add this:

public function scopeRandomize($query, $limit = 3, $exclude = [])
{
    $query = $query->whereRaw('RAND()<(SELECT ((?/COUNT(*))*10) FROM `products`)', [$limit])->orderByRaw('RAND()')->limit($limit);
    if (!empty($exclude)) {
        $query = $query->whereNotIn('id', $exclude);
    }
    return $query;
}

then at route/controller

$data = YourModel::randomize(8)->get();

For Visual Studio Community 2019, copying the files in the answers above (rc.exe rcdll.dll) to C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.21.27702\bin\Hostx86\x86 did the trick for me.

This can done several ways. I usually do it from my class.

From class

.image
{
    width:100%;


}

and for this your html would be:

<img class="image" src="images/image_name">

or if you want to style it using inline styling then you would just have:

<img style="width:100%; height:60px" id="image" src="images/image_name">

I however recommend doing it from your external style-sheet because as your project grows you will realize that the entire thing is easier managed with separate files for your html and your css.

The command to ignore multiple entries is a little tricky and requires backslashes.

svn propset svn:ignore "cache\
tmp\
null\
and_so_on" .

This command will ignore anything named cache, tmp, null, and and_so_on in the current directory.

Using Object isting. Java function to check if specified key exist in AWS S3.

boolean isExist(String key)
    {
        ObjectListing objects = amazonS3.listObjects(new ListObjectsRequest().withBucketName(bucketName).withPrefix(key));

        for (S3ObjectSummary objectSummary : objects.getObjectSummaries())
        {
            if (objectSummary.getKey().equals(key))
            {
                return true;
            }

        }
        return false;
    }

For more advanced GET/POST requests, you can install the CURL library (http://us3.php.net/curl):

$ch = curl_init("REMOTE XML FILE URL GOES HERE"); // such as http://example.com/example.xml
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HEADER, 0);
$data = curl_exec($ch);
curl_close($ch);

I had the same problem, when i loaded a text file via fs.readFile(), I tried to set the encodeing to UTF8, it keeped the same. my solution now is this:

myString = JSON.parse( JSON.stringify( myString ) )

after this an Ö is realy interpreted as an Ö.

string str = @"""Hi, "" I am programmer";

OUTPUT - "Hi, " I am programmer

sudo at now

The correct value for the content attribute should include initial-scale instead:

<meta name="viewport" content="width=device-width, initial-scale=1">_x000D_
                                                   ^^^^^^^^^^^^^^^

@KingCrunch's answer should work in many cases. One issue that can arise is you may be on a different machine that needs to pull the latest from test. So, I recommend pulling test first. The revision looks like this:

git checkout test
git pull
git checkout master
git pull origin master
git merge test
git push origin master

can you check whether you connected to the correct database. as i was faced same issue, but finally i found that i connected to different database.

identity supports identity columns in DB2, MySQL, MS SQL Server, Sybase and HypersonicSQL. The returned identifier is of type long, short or int.

This is the best way, I know of to create dynamic variables in python.

my_dict = {}
x = "Buffalo"
my_dict[x] = 4

In order to install Compass on Yosemite you need to set up the Ruby environment and to install the Xcode Command Line Tools. But, most important thing, after updating Xcode, be sure to launch the Xcode application and accept the Apple license terms. It will complete the installation of the components. After that, you can install Compass: sudo gem install compass

Use sortedWith to sort a list with Comparator.

You can then construct a comparator using several ways:

• compareBy, thenBy construct the comparator in a chain of calls:

  list.sortedWith(compareBy<Person> { it.age }.thenBy { it.name }.thenBy { it.address })
  

• compareBy has an overload which takes multiple functions:

  list.sortedWith(compareBy({ it.age }, { it.name }, { it.address }))
  

Clearing the Cache of your React Native Project: if you are sure the module exists, try this steps:

1. Clear watchman watches: npm watchman watch-del-all
2. Delete node_modules: rm -rf node_modules and run yarn install
3. Reset Metro's cache: yarn start --reset-cache
4. Remove the cache: rm -rf /tmp/metro-*

Try this:

String[] arr = new String[3];// if size is fixed otherwise use ArrayList.
int i=0;
while((str = in.readLine()) != null)          
    arr[i++] = str;

System.out.println(Arrays.toString(arr));

Setting the dialog cancelable to be false is enough, and either you touch outside of the alert dialog or click the back button will make the alert dialog disappear. So use this one:

setCancelable(false)

And the other function is not necessary anymore: dialog.setCanceledOnTouchOutside(false);

If you are creating a temporary dialog and wondering there to put this line of code, here is an example:

new AlertDialog.Builder(this)
                        .setTitle("Trial Version")
                        .setCancelable(false)
                        .setMessage("You are using trial version!")
                        .setIcon(R.drawable.time_left)
                        .setPositiveButton(android.R.string.yes, null).show();

It seems like a bug in Safari's cache handling policies.

Workaround in apache:

Header unset ETag
Header unset Last-Modified

Even if you do start the executable outside Visual Studio, you can still use the "Attach" command to connect Visual Studio to your already-running executable. This can be useful e.g. when your application is run as a plug-in within another application.

You could do something like this: Use ng-pattern with the RegExp "/^[0-9]+$/" that means only integer numbers are valid.

<form novalidate name="form">
    <input type="text" data-ng-model="age" id="age" name="age" ng-pattern="/^[0-9]+$/">
    <span ng-show="form.age.$error.pattern">The value is not a valid integer</span>
</form>

I'm showing that a combination of lines.pop(0) l.remove() and del l does the trick.

from matplotlib import pyplot
import numpy, weakref
a = numpy.arange(int(1e3))
fig = pyplot.Figure()
ax  = fig.add_subplot(1, 1, 1)
lines = ax.plot(a)

l = lines.pop(0)
wl = weakref.ref(l)  # create a weak reference to see if references still exist
#                      to this object
print wl  # not dead
l.remove()
print wl  # not dead
del l
print wl  # dead  (remove either of the steps above and this is still live)

I checked your large dataset and the release of the memory is confirmed on the system monitor as well.

Of course the simpler way (when not trouble-shooting) would be to pop it from the list and call remove on the line object without creating a hard reference to it:

lines.pop(0).remove()

Updating @Chackle's answer for Swift 2.x:

override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
    if let touch = touches.first {
        let currentPoint = touch.locationInView(self)
        // do something with your currentPoint
    }
}

override func touchesMoved(touches: Set<UITouch>, withEvent event: UIEvent?) {
    if let touch = touches.first {
        let currentPoint = touch.locationInView(self)
        // do something with your currentPoint
    }
}

override func touchesEnded(touches: Set<UITouch>, withEvent event: UIEvent?) {
    if let touch = touches.first {
        let currentPoint = touch.locationInView(self)
        // do something with your currentPoint
    }
}

Missing space between elif and [ rest your program is correct. you need to correct it an check it out. here is fixed program:

#!/bin/bash

if [ "$seconds" -eq 0 ]; then
   timezone_string="Z"
elif [ "$seconds" -gt 0 ]; then
   timezone_string=$(printf "%02d:%02d" $((seconds/3600)) $(((seconds / 60) % 60)))
else
   echo "Unknown parameter"
fi

I've had to do something like this when using commons-httpclient to access an internal https server with a self-signed certificate. Yes, our solution was to create a custom TrustManager that simply passed everything (logging a debug message).

This comes down to having our own SSLSocketFactory that creates SSL sockets from our local SSLContext, which is set up to have only our local TrustManager associated with it. You don't need to go near a keystore/certstore at all.

So this is in our LocalSSLSocketFactory:

static {
    try {
        SSL_CONTEXT = SSLContext.getInstance("SSL");
        SSL_CONTEXT.init(null, new TrustManager[] { new LocalSSLTrustManager() }, null);
    } catch (NoSuchAlgorithmException e) {
        throw new RuntimeException("Unable to initialise SSL context", e);
    } catch (KeyManagementException e) {
        throw new RuntimeException("Unable to initialise SSL context", e);
    }
}

public Socket createSocket(String host, int port) throws IOException, UnknownHostException {
    LOG.trace("createSocket(host => {}, port => {})", new Object[] { host, new Integer(port) });

    return SSL_CONTEXT.getSocketFactory().createSocket(host, port);
}

Along with other methods implementing SecureProtocolSocketFactory. LocalSSLTrustManager is the aforementioned dummy trust manager implementation.

When you assign a variable (x = ...), you are creating a variable in the current scope (e.g. local to the current function). If it happens to shadow a variable fron an outer (e.g. global) scope, well too bad - Python doesn't care (and that's a good thing). So you can't do this:

x = 0
def f():
    x = 1
f()
print x #=>0

and expect 1. Instead, you need do declare that you intend to use the global x:

x = 0
def f():
    global x
    x = 1
f()
print x #=>1

But note that assignment of a variable is very different from method calls. You can always call methods on anything in scope - e.g. on variables that come from an outer (e.g. the global) scope because nothing local shadows them.

Also very important: Member assignment (x.name = ...), item assignment (collection[key] = ...), slice assignment (sliceable[start:end] = ...) and propably more are all method calls as well! And therefore you don't need global to change a global's members or call it methods (even when they mutate the object).

Because the < operator (and most others) are binary operators (they take two arguments), and (true true) is not a valid boolean expression.

The Java language designers could have designed the language to allow syntax like the type you prefer, but (I'm guessing) they decided that it was not worth the more complex parsing rules.

An array "decays" into a pointer to its first element, so scanf("%s", string) is equivalent to scanf("%s", &string[0]). On the other hand, scanf("%s", &string) passes a pointer-to-char[256], but it points to the same place.

Then scanf, when processing the tail of its argument list, will try to pull out a char *. That's the Right Thing when you've passed in string or &string[0], but when you've passed in &string you're depending on something that the language standard doesn't guarantee, namely that the pointers &string and &string[0] -- pointers to objects of different types and sizes that start at the same place -- are represented the same way.

I don't believe I've ever encountered a system on which that doesn't work, and in practice you're probably safe. None the less, it's wrong, and it could fail on some platforms. (Hypothetical example: a "debugging" implementation that includes type information with every pointer. I think the C implementation on the Symbolics "Lisp Machines" did something like this.)

I followed the instructions http://springflex.blogspot.ru/2014/02/how-to-fix-valueerror-when-trying-to.html. but nothing happened.

Is a decent approximation on big screens. Its not good, but a good dirty fix.

So make a temporary dict with the key being the id. This filters out the duplicates. The values() of the dict will be the list

In Python2.7

>>> L=[
... {'id':1,'name':'john', 'age':34},
... {'id':1,'name':'john', 'age':34},
... {'id':2,'name':'hanna', 'age':30},
... ]
>>> {v['id']:v for v in L}.values()
[{'age': 34, 'id': 1, 'name': 'john'}, {'age': 30, 'id': 2, 'name': 'hanna'}]

In Python3

>>> L=[
... {'id':1,'name':'john', 'age':34},
... {'id':1,'name':'john', 'age':34},
... {'id':2,'name':'hanna', 'age':30},
... ] 
>>> list({v['id']:v for v in L}.values())
[{'age': 34, 'id': 1, 'name': 'john'}, {'age': 30, 'id': 2, 'name': 'hanna'}]

In Python2.5/2.6

>>> L=[
... {'id':1,'name':'john', 'age':34},
... {'id':1,'name':'john', 'age':34},
... {'id':2,'name':'hanna', 'age':30},
... ] 
>>> dict((v['id'],v) for v in L).values()
[{'age': 34, 'id': 1, 'name': 'john'}, {'age': 30, 'id': 2, 'name': 'hanna'}]

Suppose your existing reporting query is

Select EmployeeId,EmployeeName 
from Employee 
Where EmployeeId>101 order by EmployeeName

and you have to save this data into temparory table then you query goes to

Select EmployeeId,EmployeeName 
into #MyTempTable

Apparently the files were added in remote repository, no matter what was the content of .gitignore file in the origin.

As the files exist in the remote repository, git has to pull them to your local work tree as well and therefore complains that the files already exist.

.gitignore is used only for scanning for the newly added files, it doesn't have anything to do with the files which were already added.

So the solution is to remove the files in your work tree and pull the latest version. Or the long-term solution is to remove the files from the repository if they were added by mistake.

A simple example to remove files from the remote branch is to

$git checkout <brachWithFiles>
$git rm -r *.extension
$git commit -m "fixin...."
$git push

Then you can try the $git merge again

Qt works very well with graphics. In my opinion it is more versatile than PIL.

You get all the features you want for graphics manipulation, but there's also vector graphics and even support for real printers. And all of that in one uniform API, QPainter.

To use Qt you need a Python binding for it: PySide or PyQt4.
They both support Python 3.

Here is a simple example that loads a JPG image, draws an antialiased circle of radius 10 at coordinates (20, 20) with the color of the pixel that was at those coordinates and saves the modified image as a PNG file:

from PySide.QtCore import *
from PySide.QtGui import *

app = QCoreApplication([])

img = QImage('input.jpg')

g = QPainter(img)
g.setRenderHint(QPainter.Antialiasing)
g.setBrush(QColor(img.pixel(20, 20)))
g.drawEllipse(QPoint(20, 20), 10, 10)
g.end()

img.save('output.png')

But please note that this solution is quite 'heavyweight', because Qt is a large framework for making GUI applications.

Well, I cant find any SecondaryInstaller.exe to stop in task manager and even I dont have any AV rather then Windows Defender so I found something else..
I stopped windows Update from elevated cmd by writing command net stop muauserv and it worked for me...
The update will Retry again for KB2664825 so run the code again in cmd..(because the service starts automatically)

Keep trying and its done for me...!!

Silly answer but if you can't figure out why its not redirecting check that the following is enabled for the web folder ..

AllowOverride All

This will enable you to run htaccess which must be running! (there are alternatives but not on will cause problems https://httpd.apache.org/docs/2.4/mod/core.html#allowoverride)

The problem is that the true y is binary (zeros and ones), while your predictions are not. You probably generated probabilities and not predictions, hence the result :) Try instead to generate class membership, and it should work!
