Just for the sake of a more complete answer, here's a working way for truncating to any of the date parts down and including minutes (replace GETDATE() with the date to truncate).

This is different from the accepted answer in that you can use not only dd (days), but any of the date parts (see here):

dateadd(minute, datediff(minute, 0, GETDATE()), 0)

Note that in the expression above, the 0 is a constant date on the beginning of a year (1900-01-01). If you need to truncate to smaller parts, such as to seconds or milliseconds, you need to take a constant date which is closer to the date to be truncated to avoid an overflow.

ObservableCollection is a collection that allows code outside the collection be aware of when changes to the collection (add, move, remove) occur. It is used heavily in WPF and Silverlight but its use is not limited to there. Code can add event handlers to see when the collection has changed and then react through the event handler to do some additional processing. This may be changing a UI or performing some other operation.

The code below doesn't really do anything but demonstrates how you'd attach a handler in a class and then use the event args to react in some way to the changes. WPF already has many operations like refreshing the UI built in so you get them for free when using ObservableCollections

class Handler
{
    private ObservableCollection<string> collection;

    public Handler()
    {
        collection = new ObservableCollection<string>();
        collection.CollectionChanged += HandleChange;
    }

    private void HandleChange(object sender, NotifyCollectionChangedEventArgs e)
    {
        foreach (var x in e.NewItems)
        {
            // do something
        }

        foreach (var y in e.OldItems)
        {
            //do something
        }
        if (e.Action == NotifyCollectionChangedAction.Move)
        {
            //do something
        }
    }
}

If it's just for passing values between pages and you only require it for the one request. Use Context.

Context

The Context object holds data for a single user, for a single request, and it is only persisted for the duration of the request. The Context container can hold large amounts of data, but typically it is used to hold small pieces of data because it is often implemented for every request through a handler in the global.asax. The Context container (accessible from the Page object or using System.Web.HttpContext.Current) is provided to hold values that need to be passed between different HttpModules and HttpHandlers. It can also be used to hold information that is relevant for an entire request. For example, the IBuySpy portal stuffs some configuration information into this container during the Application_BeginRequest event handler in the global.asax. Note that this only applies during the current request; if you need something that will still be around for the next request, consider using ViewState. Setting and getting data from the Context collection uses syntax identical to what you have already seen with other collection objects, like the Application, Session, and Cache. Two simple examples are shown here:

// Add item to
Context Context.Items["myKey"] = myValue;

// Read an item from the
 Context Response.Write(Context["myKey"]);

http://msdn.microsoft.com/en-us/magazine/cc300437.aspx#S6

Using the above. If you then do a Server.Transfer the data you've saved in the context will now be available to the next page. You don't have to concern yourself with removing/tidying up this data as it is only scoped to the current request.

There could be two reasons an element doesn't exist:

1. Bad xpath (//*[@id'forgotQuote])
2. Correct xpath but no element (//*[contains(text(),'This text is not in the page')])

Would you get com.sun.jdi.InvocationException in either case when you are running Debug and you hover your mouse over a reference to the WeBElement (this with Selenium and Java)???

We use the following, but can't distinguish if it returns false due to bad xpath or non-existent element (valid xpath syntax):

public static boolean isElementDisplayed(WebElement element) {
    boolean isDisplayed = false;

    try {
        isDisplayed = element.isDisplayed();
    } catch (NoSuchElementException e) {
        ;// No Worries
    }
    return isDisplayed;
}

Thanks for your replies. Here's what I did:

git gc
git gc --aggressive
git prune

That seemed to have done the trick. I started with around 10.5MB and now it's little more than 980KBs.

This work for Checkbox too.

public class EnumToBoolConverter:IValueConverter
{
    private int val;
    public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
    {
        int intParam = (int)parameter;
        val = (int)value;

        return ((intParam & val) != 0);
    }

    public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
    {
        val ^= (int)parameter;
        return Enum.Parse(targetType, val.ToString());
    }
}

Binding a single enum to multiple checkboxes.

("#tblEntAttributes tbody")

needs to be

$("#tblEntAttributes tbody").

You are not selecting the element with the correct syntax

Here's an example of both

$(newRowContent).appendTo($("#tblEntAttributes"));

and

$("#tblEntAttributes tbody").append(newRowContent);

The short answer taken from the announcement of jQuery 3.0 Final Release :

Along with the regular version of jQuery that includes the ajax and effects modules, we’re releasing a “slim” version that excludes these modules. All in all, it excludes ajax, effects, and currently deprecated code.

The file size (gzipped) is about 6k smaller, 23.6k vs 30k.

This demo is returning correctly for me in Chrome 14, FF3 and FF5 (with Firebug):

var mytextvalue = document.getElementById("mytext").value;
console.log(mytextvalue == ''); // true
console.log(mytextvalue == null); // false

and changing the console.log to alert, I still get the desired output in IE6.

To display the all details for each news post title ie. "news.id" which is the primary key, you need to use GROUP BY clause for "news.id"

SELECT news.id, users.username, news.title, news.date,
       news.body, COUNT(comments.id)
FROM news
LEFT JOIN users
ON news.user_id = users.id
LEFT JOIN comments
ON comments.news_id = news.id
GROUP BY news.id

Check the Debug class. http://developer.android.com/reference/android/os/Debug.html i.e. Debug.getNativeHeapAllocatedSize()

It has methods to get the used native heap, which is i.e. used by external bitmaps in your app. For the heap that the app is using internally, you can see that in the DDMS tool that comes with the Android SDK and is also available via Eclipse.

The native heap + the heap as indicated in the DDMS make up the total heap that your app is allocating.

For CPU usage I'm not sure if there's anything available via API/SDK.

The best way is to use simple math

>>> a = 8
>>> a**(1./3.)
2.0

EDIT

For Negative numbers

>>> a = -8
>>> -(-a)**(1./3.)
-2.0

Complete Program for all the requirements as specified

x = int(input("Enter an integer: "))
if x>0:
    ans = x**(1./3.)
    if ans ** 3 != abs(x):
        print x, 'is not a perfect cube!'
else:
    ans = -((-x)**(1./3.))
    if ans ** 3 != -abs(x):
        print x, 'is not a perfect cube!'

print 'Cube root of ' + str(x) + ' is ' + str(ans)

I don't like the accepted answer or @fivetwentysix's comment regarding how to solve this. It gets at one method for doing this, but doesn't give the full solution to using toArray. You need to use toArray and give it an argument that's an array of the correct type and size so that you don't end up with an Object array. While an object array will work, I don't think it's best practice in a strongly typed language.

String[] array = arrayList.toArray(new String[arrayList.size()]);
JComboBox comboBox = new JComboBox(array);

Alternatively, you can also maintain strong typing by just using a for loop.

String[] array = new String[arrayList.size()];
for(int i = 0; i < array.length; i++) {
    array[i] = arrayList.get(i);
}
JComboBox comboBox = new JComboBox(array);

How about something like this.

Test the live example: http://jsfiddle.net/6hBZU/1/

It assumes that the string will always end with the extension:

function openFile(file) {
    var extension = file.substr( (file.lastIndexOf('.') +1) );
    switch(extension) {
        case 'jpg':
        case 'png':
        case 'gif':
            alert('was jpg png gif');  // There's was a typo in the example where
        break;                         // the alert ended with pdf instead of gif.
        case 'zip':
        case 'rar':
            alert('was zip rar');
        break;
        case 'pdf':
            alert('was pdf');
        break;
        default:
            alert('who knows');
    }
};

openFile("somestring.png");

EDIT: I mistakenly deleted part of the string in openFile("somestring.png");. Corrected. Had it in the Live Example, though.

string = string.replace(/[\W_]/g, "_");

I think you mean to update it back to the OLD password, when the NEW one is not supplied.

DROP TRIGGER IF EXISTS upd_user;

DELIMITER $$

    CREATE TRIGGER upd_user BEFORE UPDATE ON `user`
    FOR EACH ROW BEGIN
      IF (NEW.password IS NULL OR NEW.password = '') THEN
            SET NEW.password = OLD.password;
      ELSE
            SET NEW.password = Password(NEW.Password);
      END IF;
    END$$

DELIMITER ;

However, this means a user can never blank out a password.

DELIMITER $$

    CREATE TRIGGER upd_user BEFORE UPDATE ON `user`
    FOR EACH ROW BEGIN
      IF (NEW.password IS NULL OR NEW.password = '' OR NEW.password = OLD.password) THEN
            SET NEW.password = OLD.password;
      ELSE
            SET NEW.password = Password(NEW.Password);
      END IF;
    END$$

DELIMITER ;

It's part of the ES6 module system, described here. There is a helpful example in that documentation, also:

If a module defines a default export:

export default function() { console.log("hello!") }

then you can import that default export by omitting the curly braces:

import foo from "foo";
foo(); // hello!

Update: As of June 2015, the module system is defined in §15.2 and the export syntax in particular is defined in §15.2.3 of the ECMAScript 2015 specification.

Improving Android Studio Performance on Memory-Constrained Machines

Pretty late response but you can do the following in Kotlin:

activity?.applicationContext?.let { SymptomsAdapters(it, param2, param3, ...) }

(?.) is for safe null operation to prevent from the null pointer exception.

You do not want to create a new context as that can lead to memory leaks when interchanging between fragments or when the device changes rotation.

And as someone mentioned above, in Java you can obtain context in a fragment by doing the following:

getActivity().getApplicationContext()

The accepted answer does not seem quite right to me. There is no point dragging a different version of HttpMime when one can depend on the same version of it.

compile group: 'org.apache.httpcomponents' , name: 'httpclient-android' , version: '4.3.5'
compile (group: 'org.apache.httpcomponents' , name: 'httpmime' , version: '4.3.5') {
    exclude module: 'org.apache.httpcomponents:httpclient'
}

Well its too late may be to answer but here is what i did to get results back from the DialogFragment. very similar to @brandon's answer. Here i am calling DialogFragment from a fragment, just place this code where you are calling your dialog.

FragmentManager fragmentManager = getFragmentManager();
            categoryDialog.setTargetFragment(this,1);
            categoryDialog.show(fragmentManager, "dialog");

where categoryDialog is my DialogFragment which i want to call and after this in your implementation of dialogfragment place this code where you are setting your data in intent. The value of resultCode is 1 you can set it or use system Defined.

            Intent intent = new Intent();
            intent.putExtra("listdata", stringData);
            getTargetFragment().onActivityResult(getTargetRequestCode(), resultCode, intent);
            getDialog().dismiss();

now its time to get back to to the calling fragment and implement this method. check for data validity or result success if you want with resultCode and requestCode in if condition.

 @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);        
        //do what ever you want here, and get the result from intent like below
        String myData = data.getStringExtra("listdata");
Toast.makeText(getActivity(),data.getStringExtra("listdata"),Toast.LENGTH_SHORT).show();
    }

I assume 0 means false (which is the case in a lot of programming languages). That means true is not 0 (some languages use -1 some others use 1; doesn't hurt to be compatible to either). So assuming by "better" you mean less typing, you can just write:

bool boolValue = intValue != 0;

In @Patrick McMahon's response, the second comment here ( $first_condition is false and $second_condition is true ) is not entirely accurate:

<?php if($first_condition): ?>
  /*$first_condition is true*/
  <div class="first-condition-true">First Condition is true</div>
<?php elseif($second_condition): ?>
  /*$first_condition is false and $second_condition is true*/
  <div class="second-condition-true">Second Condition is true</div>
<?php else: ?>
  /*$first_condition and $second_condition are false*/
  <div class="first-and-second-condition-false">Conditions are false</div>
<?php endif; ?>

Elseif fires whether $first_condition is true or false, as do additional elseif statements, if there are multiple.

I am no PHP expert, so I don't know whether that's the correct way to say IF this OR that ELSE that or if there is another/better way to code it in PHP, but this would be an important distinction to those looking for OR conditions versus ELSE conditions.

Source is w3schools.com and my own experience.

Probably not the most performance friendly way, but you could create a scalar function that pulls from the information schema with the table and column name, and then call that using the isnull logic you tried earlier:

    CREATE FUNCTION GetDefaultValue
    (
        @TableName VARCHAR(200),
        @ColumnName VARCHAR(200)
    )
    RETURNS VARCHAR(200)
    AS
    BEGIN
        -- you'd probably want to have different functions for different data types if
        -- you go this route
    RETURN (SELECT TOP 1 REPLACE(REPLACE(REPLACE(COLUMN_DEFAULT, '(', ''), ')', ''), '''', '') 
            FROM information_schema.columns
            WHERE table_name = @TableName AND column_name = @ColumnName)

    END
    GO

And then call it like this:

INSERT INTO t (value) VALUES ( ISNULL(@value, SELECT dbo.GetDefaultValue('t', 'value') )

get matched string back or false

function preg_match (regex, str) {
  if (new RegExp(regex).test(str)){
    return regex.exec(str);
  }
  return false;
}

The following program will add the python executable path and the subdir Scripts (which is where e.g. pip and easy_install are installed) to your environment. It finds the path to the python executable from the registry key binding the .py extension. It will remove old python paths in your environment. Works with XP (and probably Vista) as well. It only uses modules that come with the basic windows installer.

JavaScript code using ng-controller:

$scope.checkkey = function (event) {
  alert(event.keyCode);  //this will show the ASCII value of the key pressed

}

In HTML:

<input type="text" ng-keypress="checkkey($event)" />

You can now place your checks and other conditions using the keyCode method.

Try putting this HTML snippet into your served document:

<img id="ItemPreview" src="">

Then, on JavaScript side, you can dynamically modify image's src attribute with so-called Data URL.

document.getElementById("ItemPreview").src = "data:image/png;base64," + yourByteArrayAsBase64;

Alternatively, using jQuery:

$('#ItemPreview').attr('src', `data:image/png;base64,${yourByteArrayAsBase64}`);

This assumes that your image is stored in PNG format, which is quite popular. If you use some other image format (e.g. JPEG), modify the MIME type ("image/..." part) in the URL accordingly.

ASP.NET Web API is a framework that makes it easy to build HTTP services that reach a broad range of clients, including browsers and mobile devices. ASP.NET Web API is an ideal platform for building RESTful applications on the .NET Framework.

REST

RESTs sweet spot is when you are exposing a public API over the internet to handle CRUD operations on data. REST is focused on accessing named resources through a single consistent interface.

SOAP

SOAP brings it’s own protocol and focuses on exposing pieces of application logic (not data) as services. SOAP exposes operations. SOAP is focused on accessing named operations, each implement some business logic through different interfaces.

Though SOAP is commonly referred to as “web services” this is a misnomer. SOAP has very little if anything to do with the Web. REST provides true “Web services” based on URIs and HTTP.

Reference: http://spf13.com/post/soap-vs-rest

And finally: What they could be referring to is REST vs. RPC See this: http://encosia.com/rest-vs-rpc-in-asp-net-web-api-who-cares-it-does-both/

I use an extension to eliminate this problem for me, which may or may not be what you are after.

It goes like this:

public static class Extensions
{

    public String TrimString(this object item)
    {
        return String.Format("{0}", item).Trim();
    }

}

Note:

This extension does not return null values! If the item is null or DBNull.Value, it will return an empty String.

Usage:

public string GetCustomerNumber(Guid id)
{
    var obj = 
        DBSqlHelperFactory.ExecuteScalar(
            connectionStringSplendidmyApp, 
            CommandType.StoredProcedure, 
            "GetCustomerNumber", 
            new SqlParameter("@id", id)
        );
    return obj.TrimString();
}

im is "image process name" example /f /im notepad.exe is specified to kill image process name (program) notepad.exe

.classname
{
 opacity: 0.5;
}

See here: Physical Vs Virtual Memory

Virtual memory is stored on the hard drive and is used when the RAM is filled. Physical memory is limited to the size of the RAM chips installed in the computer. Virtual memory is limited by the size of the hard drive, so virtual memory has the capability for more storage.

In ES6 you can do this:

let cake = '';

let pan = {
  [cake]: '',
};

// Output -> { '': '' }

Old Way

let cake = '';
let pan = {};
pan[cake] = '';

// Output -> { '': '' }

I suggest using vlookup function to get the nearest match.

Step 1

Prepare data range and name it: 'numberRange':

Select the range. Go to menu: Data ? Named ranges... ? define the new named range.

Step 2

Use this simple formula:

=VLOOKUP(A2,numberRange,2)

This way you can ommit errors, and easily correct the result.

My two cents:
If using the Google_Client library do not forget to update the JSON file on your server after updating the redirect URI's.

This will give you the two's complement efficiently using bitwise logic:

def twos_complement(value, bitWidth):
    if value >= 2**bitWidth:
        # This catches when someone tries to give a value that is out of range
        raise ValueError("Value: {} out of range of {}-bit value.".format(value, bitWidth))
    else:
        return value - int((value << 1) & 2**bitWidth)

How it works:

First, we make sure that the user has passed us a value that is within the range of the supplied bit range (e.g. someone gives us 0xFFFF and specifies 8 bits) Another solution to that problem would be to bitwise AND (&) the value with (2**bitWidth)-1

To get the result, the value is shifted by 1 bit to the left. This moves the MSB of the value (the sign bit) into position to be anded with 2**bitWidth. When the sign bit is '0' the subtrahend becomes 0 and the result is value - 0. When the sign bit is '1' the subtrahend becomes 2**bitWidth and the result is value - 2**bitWidth

Example 1: If the parameters are value=0xFF (255d, b11111111) and bitWidth=8

1. 0xFF - int((0xFF << 1) & 2**8)
2. 0xFF - int((0x1FE) & 0x100)
3. 0xFF - int(0x100)
4. 255 - 256
5. -1

Example 2: If the parameters are value=0x1F (31d, b11111) and bitWidth=6

1. 0x1F - int((0x1F << 1) & 2**6)
2. 0x1F - int((0x3E) & 0x40)
3. 0x1F - int(0x00)
4. 31 - 0
5. 31

Example 3: value = 0x80, bitWidth = 7

ValueError: Value: 128 out of range of 7-bit value.

Example 4: value = 0x80, bitWitdh = 8

1. 0x80 - int((0x80 << 1) & 2**8)
2. 0x80 - int((0x100) & 0x100)
3. 0x80 - int(0x100)
4. 128 - 256
5. -128

Now, using what others have already posted, pass your bitstring into int(bitstring,2) and pass to the twos_complement method's value parameter.

cd C:\Users\%username%\AppData\Local rmdir /S /Q Temp

del C:\Windows\Prefetch*.* /Q

If the default value for a given type is an acceptable result:

if (v1.HasValue)
    v2 = v1.GetValueOrDefault();

If you want a different default value when the result is undefined:

v2 = v1.GetValueOrDefault(255);    // or any valid value for int in place of 255

If you just want the value returned (no matter if the method failed or not):

v2 = v1.GetValueOrDefault();

.NET 4.7.2.: GetValueOrDefault() returns the field value without any checking.

You can also specify context location relatively to current classpath, which may be preferable

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath*:applicationContext*.xml</param-value>
</context-param>

<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

ulimit -s unlimited lets the stack grow unlimited.

This may prevent your program from crashing if you write programs by recursion, especially if your programs are not tail recursive (compilers can "optimize" those), and the depth of recursion is large.

Firebug is great, but Safari provides its own built-in development tools.

If you haven't already tried Safari's development kit, go to Safari-->Preferences-->Advanced, and check the box next to "Show Develop menu in menu bar".

Once you have the Develop menu enabled, you can use the Web Inspector to get a lot of the same functionality that Firebug provides.

Not sure I fully understand your question, but is this what you want to do?

pd.DataFrame(data=dict(s1=s1, s2=s2), index=s1.index)

(index=s1.index is not even necessary here)

C# Thread.Abort is NOT guaranteed to abort the thread instantaneously. It will probably work when a thread calls Abort on itself but not when a thread calls on another.

Please refer to the documentation: http://msdn.microsoft.com/en-us/library/ty8d3wta.aspx

I have faced this problem writing tools that interact with hardware - you want immediate stop but it is not guaranteed. I typically use some flags or other such logic to prevent execution of parts of code running on a thread (and which I do not want to be executed on abort - tricky).

Since all of the solutions to date used fluent syntax, here is a solution in query expression syntax, for those interested:

var peopleDifference = 
  from person2 in peopleList2
  where !(
      from person1 in peopleList1 
      select person1.ID
    ).Contains(person2.ID)
  select person2;

I think it is different enough from the answers given to be of interest to some, even thought it most likely would be suboptimal for Lists. Now for tables with indexed IDs, this would definitely be the way to go.

An application binary interface (ABI) is similar to an API, but the function is not accessible to the caller at source code level. Only a binary representation is accessible/available.

ABIs may be defined at the processor-architecture level or at the OS level. The ABIs are standards to be followed by the code-generator phase of the compiler. The standard is fixed either by the OS or by the processor.

Functionality: Define the mechanism/standard to make function calls independent of the implementation language or a specific compiler/linker/toolchain. Provide the mechanism which allows JNI, or a Python-C interface, etc.

Existing entities: Functions in machine code form.

Consumer: Another function (including one in another language, compiled by another compiler, or linked by another linker).

To execute more Maven builds from one script you shall use the Windows call function in the following way:

call mvn install:install-file -DgroupId=gdata -DartifactId=base -Dversion=1.0 -Dfile=gdata-base-1.0.jar  -Dpackaging=jar -DgeneratePom=true
call mvn install:install-file -DgroupId=gdata -DartifactId=blogger -Dversion=2.0 -Dfile=gdata-blogger-2.0.jar  -Dpackaging=jar -DgeneratePom=true
call mvn install:install-file -DgroupId=gdata -DartifactId=blogger-meta -Dversion=2.0 -Dfile=gdata-blogger-meta-2.0.jar  -Dpackaging=jar -DgeneratePom=true

If column A contains the amounts to be reimbursed, and column B contains the "yes/no" indicating whether the reimbursement has been made, then either of the following will work, though the first option is recommended:

=SUMIF(B:B,"No",A:A)

or

=SUMIFS(A:A,B:B,"No")

Here is an example that will display the amounts paid and outstanding for a small set of sample data.

 A         B            C                   D
 Amount    Reimbursed?  Total Paid:         =SUMIF(B:B,"Yes",A:A)
 $100      Yes          Total Outstanding:  =SUMIF(B:B,"No",A:A)
 $200      No           
 $300      No
 $400      Yes
 $500      No

To implement you need use Typeface go through with sample below

Typeface typeface = Typeface.createFromAsset(getAssets(), "fonts/Roboto/Roboto-Regular.ttf");
for (View view : allViews)
{
   if (view instanceof TextView) 
   {
      TextView textView = (TextView) view;
      textView.setTypeface(typeface);
      }
   }
}

First, you should use any WebSocket or polling mechanics to notify the frontend part about changes that happened. I use Flask-SocketIO wrapper, and very happy with async messaging for my tiny apps.

Nest, you can do all logic which you need in a separate thread(s), and notify the frontend via SocketIO object (Flask holds continuous open connection with every frontend client).

As an example, I just implemented page reload on backend file modifications:

<!doctype html>
<script>
    sio = io()

    sio.on('reload',(info)=>{
        console.log(['sio','reload',info])
        document.location.reload()
    })
</script>

class App(Web, Module):

    def __init__(self, V):
        ## flask module instance
        self.flask = flask
        ## wrapped application instance
        self.app = flask.Flask(self.value)
        self.app.config['SECRET_KEY'] = config.SECRET_KEY
        ## `flask-socketio`
        self.sio = SocketIO(self.app)
        self.watchfiles()

    ## inotify reload files after change via `sio(reload)``
    def watchfiles(self):
        from watchdog.observers import Observer
        from watchdog.events import FileSystemEventHandler
        class Handler(FileSystemEventHandler):
            def __init__(self,sio):
                super().__init__()
                self.sio = sio
            def on_modified(self, event):
                print([self.on_modified,self,event])
                self.sio.emit('reload',[event.src_path,event.event_type,event.is_directory])
        self.observer = Observer()
        self.observer.schedule(Handler(self.sio),path='static',recursive=True)
        self.observer.schedule(Handler(self.sio),path='templates',recursive=True)
        self.observer.start()

Using OlebDB, we can read excel file in C#, easily, here is the code while working with Web-Form, where FileUpload1 is file uploading tool

   string path = Server.MapPath("~/Uploads/");
  if (!Directory.Exists(path))
{
    Directory.CreateDirectory(path);
}
//get file path
filePath = path + Path.GetFileName(FileUpload1.FileName);
//get file extenstion
string extension = Path.GetExtension(FileUpload1.FileName);
//save file on "Uploads" folder of project
FileUpload1.SaveAs(filePath);

string conString = string.Empty;
//check file extension
switch (extension)
{
    case ".xls": //Excel 97-03.
        conString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=Excel03ConString;Extended Properties='Excel 8.0;HDR=YES'";
        break;
    case ".xlsx": //Excel 07 and above.
        conString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=Excel07ConString;Extended Properties='Excel 8.0;HDR=YES'";
        break;
}

//create datatable object
DataTable dt = new DataTable();
conString = string.Format(conString, filePath);

//Use OldDb to read excel
using (OleDbConnection connExcel = new OleDbConnection(conString))
{
    using (OleDbCommand cmdExcel = new OleDbCommand())
    {
        using (OleDbDataAdapter odaExcel = new OleDbDataAdapter())
        {
            cmdExcel.Connection = connExcel;

            //Get the name of First Sheet.
            connExcel.Open();
            DataTable dtExcelSchema;
            dtExcelSchema = connExcel.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null);
            string sheetName = dtExcelSchema.Rows[0]["TABLE_NAME"].ToString();
            connExcel.Close();

            //Read Data from First Sheet.
            connExcel.Open();
            cmdExcel.CommandText = "SELECT * From [" + sheetName + "]";
            odaExcel.SelectCommand = cmdExcel;
            odaExcel.Fill(dt);
            connExcel.Close();
        }
    }
}

//bind datatable with GridView
GridView1.DataSource = dt;
GridView1.DataBind();

.NET has spoiled us :) Your declaration is not valid for VBA.

Only constants can be given a value upon application load. You declare them like so:

Public Const APOSTROPHE_KEYCODE = 222

Here's a sample declaration from one of my vba projects:

If you're looking for something where you declare a public variable and then want to initialize its value, you need to create a Workbook_Open sub and do your initialization there. Example:

Private Sub Workbook_Open()
  Dim iAnswer As Integer

  InitializeListSheetDataColumns_S
  HideAllMonths_S

  If sheetSetupInfo.Range("D6").Value = "Enter Facility Name" Then
    iAnswer = MsgBox("It appears you have not yet set up this workbook.  Would you like to do so now?", vbYesNo)
    If iAnswer = vbYes Then
      sheetSetupInfo.Activate
      sheetSetupInfo.Range("D6").Select
      Exit Sub
    End If
  End If

  Application.Calculation = xlCalculationAutomatic
  sheetGeneralInfo.Activate
  Load frmInfoSheet
  frmInfoSheet.Show


End Sub

Make sure you declare the sub in the Workbook Object itself:

The override keyword serves two purposes:

1. It shows the reader of the code that "this is a virtual method, that is overriding a virtual method of the base class."
2. The compiler also knows that it's an override, so it can "check" that you are not altering/adding new methods that you think are overrides.

To explain the latter:

class base
{
  public:
    virtual int foo(float x) = 0; 
};


class derived: public base
{
   public:
     int foo(float x) override { ... } // OK
}

class derived2: public base
{
   public:
     int foo(int x) override { ... } // ERROR
};

In derived2 the compiler will issue an error for "changing the type". Without override, at most the compiler would give a warning for "you are hiding virtual method by same name".

This is what I did to solve this error:

1) I copied a folder named "folder1" (and I called the new folder "folder2"). "folder1" was a Netbeans project so it had a folder called "nbproject" inside it.

2) When I tried to create a project out of the "folder2", Netbeans threw an error "Sources directory is already netbeans project (maybe only in memory)."

3) Inside Netbeans delete the project of "folder1". Then, delete the two folders named "nbproject" (one is inside "folder1" and the other is inside "folder2").

4) Inside Netbeans, create two new projects: one for "folder1" and another for "folder2". The error should not appear anymore.

I had this error once and it ended up being the server's hard drive that run out of disk space.

I use Eclipse's Database development plugins - like all Java based SQL editors, it works cross platform with any type 4 (ie pure Java) JDBC driver. It's ok for basic stuff (the main failing is it struggles to give transaction control -- auto-commit=true is always set it seems).

Microsoft have a decent JDBC type 4 driver: http://www.microsoft.com/downloads/details.aspx?FamilyId=6D483869-816A-44CB-9787-A866235EFC7C&displaylang=en this can be used with all Java clients / programs on Win/Mac/Lin/etc.

Those people struggling with Java/JDBC on a Mac are presumably trying to use native drivers instead of JDBC ones -- I haven't used (or practically heard of) the ODBC driver bridge in almost 10 years.

The > selector matches direct children only, not descendants.

You want

div.test th, td, caption {}

or more likely

div.test th, div.test td, div.test caption {}

Edit:

The first one says

  div.test th, /* any <th> underneath a <div class="test"> */
  td,          /* or any <td> anywhere at all */
  caption      /* or any <caption> */

Whereas the second says

  div.test th,     /* any <th> underneath a <div class="test"> */
  div.test td,     /* or any <td> underneath a <div class="test"> */
  div.test caption /* or any <caption> underneath a <div class="test">  */

In your original the div.test > th says any <th> which is a **direct** child of <div class="test">, which means it will match <div class="test"><th>this</th></div> but won't match <div class="test"><table><th>this</th></table></div>

Use anonymous class

Shape your model the way you want using anonymous classes:

var root = new 
{ 
    car = new 
    { 
        name = "Ford", 
        owner = "Henry"
    }
};

string json = JsonConvert.SerializeObject(root);

Maybe this example listed here can help you out. Statement from the author

about 24 lines of code to encrypt, 23 to decrypt

In response to the above post I think it needs this line instead of your line:-

var strMethodUrl = '@Url.Action("SubMenu_Click", "Logging")?param1='+value1+' &param2='+value2

Or else you send the actual strings value1 and value2 to the controller.

However, for me, it only calls the controller once. It seems to hit 'receieveResponse' each time, but a break point on the controller method shows it is only hit 1st time until a page refresh.

Here is a working solution. For the cshtml page:-

   <button type="button" onclick="ButtonClick();"> Call &raquo;</button>

<script>
    function ButtonClick()
    {
        callControllerMethod2("1", "2");
    }
    function callControllerMethod2(value1, value2)
    {
        var response = null;
        $.ajax({
            async: true,
            url: "Logging/SubMenu_Click?param1=" + value1 + " &param2=" + value2,
            cache: false,
            dataType: "json",
            success: function (data) { receiveResponse(data); }
        });
    }
    function receiveResponse(response)
    {
        if (response != null)
        {
            for (var i = 0; i < response.length; i++)
            {
                alert(response[i].Data);
            }
        }
    }
</script>

And for the controller:-

public class A
{
    public string Id { get; set; }
    public string Data { get; set; }

}
public JsonResult SubMenu_Click(string param1, string param2)
{
    A[] arr = new A[] {new A(){ Id = "1", Data = DateTime.Now.Millisecond.ToString() } };
    return Json(arr , JsonRequestBehavior.AllowGet);
}

You can see the time changing each time it is called, so there is no caching of the values...

You should use the following:

$('#gentab').on('click', 'a.tabclick', function(event) {
    event.preventDefault();
    var liId = $(this).closest("li").attr("id");
    alert(liId);  
});

This will attach your event to any anchors within the #gentab element, reducing the scope of having to check the whole document element tree and increasing efficiency.

var test = $('#id').attr('value').match(/[^a-z0-9 ]+/);

Here you go!

Simple solution that actually renames the elements in-place, not creating a copy, and does a pretty good job of replacing the attributes.

public void RemoveAllNamespaces(ref XElement value)
{
  List<XAttribute> attributesToRemove = new List<XAttribute>();
  foreach (void e_loopVariable in value.DescendantsAndSelf) {
    e = e_loopVariable;
    if (e.Name.Namespace != XNamespace.None) {
      e.Name = e.Name.LocalName;
    }
    foreach (void a_loopVariable in e.Attributes) {
      a = a_loopVariable;
      if (a.IsNamespaceDeclaration) {
        //do not keep it at all
        attributesToRemove.Add(a);
      } else if (a.Name.Namespace != XNamespace.None) {
        e.SetAttributeValue(a.Name.LocalName, a.Value);
        attributesToRemove.Add(a);
      }
    }
  }
  foreach (void a_loopVariable in attributesToRemove) {
    a = a_loopVariable;
    a.Remove();
  }
}

Note: this does not always preserve original attribute order, but I'm sure you could change it to do that pretty easily if it's important to you.

Also note that this also could throw an exception, if you had an XElement attributes that are only unique with the namespace, like:

<root xmlns:ns1="a" xmlns:ns2="b">
    <elem ns1:dupAttrib="" ns2:dupAttrib="" />
</root>

which really seems like an inherent problem. But since the question indicated outputing a String, not an XElement, in this case you could have a solution that would output a valid String that was an invalid XElement.

I also liked jocull's answer using a custom XmlWriter, but when I tried it, it did not work for me. Although it all looks correct, I couldn't tell if the XmlNoNamespaceWriter class had any effect at all; it definitely was not removing the namespaces as I wanted it to.

There are couple of different solutions to achieve this:

1 - Native javascript for-in loop:

const result = {};
let key;

for (key in obj1) {
  if(obj1.hasOwnProperty(key)){
    result[key] = obj1[key];
  }
}

for (key in obj2) {
  if(obj2.hasOwnProperty(key)){
    result[key] = obj2[key];
  }
}

2 - Object.keys():

const result = {};

Object.keys(obj1)
  .forEach(key => result[key] = obj1[key]);

Object.keys(obj2)
  .forEach(key => result[key] = obj2[key]);

3 - Object.assign():
(Browser compatibility: Chrome: 45, Firefox (Gecko): 34, Internet Explorer: No support, Edge: (Yes), Opera: 32, Safari: 9)

const result = Object.assign({}, obj1, obj2);

4 - Spread Operator:
Standardised from ECMAScript 2015 (6th Edition, ECMA-262):

Defined in several sections of the specification: Array Initializer, Argument Lists

Using this new syntax you could join/merge different objects into one object like this:

const result = {
  ...obj1,
  ...obj2,
};

5 - jQuery.extend(target, obj1, obj2):

Merge the contents of two or more objects together into the first object.

const target = {};

$.extend(target, obj1, obj2);

6 - jQuery.extend(true, target, obj1, obj2):

Run a deep merge of the contents of two or more objects together into the target. Passing false for the first argument is not supported.

const target = {};

$.extend(true, target, obj1, obj2);

7 - Lodash _.assignIn(object, [sources]): also named as _.extend:

const result = {};

_.assignIn(result, obj1, obj2);

8 - Lodash _.merge(object, [sources]):

const result = _.merge(obj1, obj2);

There are a couple of important differences between lodash's merge function and Object.assign:

1- Although they both receive any number of objects but lodash's merge apply a deep merge of those objects but Object.assign only merges the first level. For instance:

_.isEqual(_.merge({
  x: {
    y: { key1: 'value1' },
  },
}, {
  x: {
    y: { key2: 'value2' },
  },
}), {
  x: {
    y: {
      key1: 'value1',
      key2: 'value2',
    },
  },
}); // true

BUT:

const result = Object.assign({
  x: {
    y: { key1: 'value1' },
  },
}, {
  x: {
    y: { key2: 'value2' },
  },
});
_.isEqual(result, {
  x: {
    y: {
      key1: 'value1',
      key2: 'value2',
    },
  },
}); // false
// AND
_.isEqual(result, {
  x: {
    y: {
      key2: 'value2',
    },
  },
}); // true

2- Another difference has to do with how Object.assign and _.merge interpret the undefined value:

_.isEqual(_.merge({x: 1}, {x: undefined}), { x: 1 }) // false

BUT:

_.isEqual(Object.assign({x: 1}, {x: undefined}), { x: undefined })// true

Update 1:

When using for in loop in JavaScript, we should be aware of our environment specially the possible prototype changes in the JavaScript types. For instance some of the older JavaScript libraries add new stuff to Array.prototype or even Object.prototype. To safeguard your iterations over from the added stuff we could use object.hasOwnProperty(key) to mke sure the key is actually part of the object you are iterating over.

Update 2:

I updated my answer and added the solution number 4, which is a new JavaScript feature but not completely standardized yet. I am using it with Babeljs which is a compiler for writing next generation JavaScript.

Update 3:
I added the difference between Object.assign and _.merge.

It looks as if you are using the URL.toString result as the argument to the FileReader constructor. URL.toString is a bit broken, and instead you should generally use url.toURI().toString(). In any case, the string is not a file path.

Instead, you should either:

• Pass the URL to ServicesLoader and let it call openStream or similar.
• Use Class.getResourceAsStream and just pass the stream over, possibly inside an InputSource. (Remember to check for nulls as the API is a bit messy.)

Since I recommended printf in a comment, I should probably give some examples of its usage (although for printing a usage message, I'd be more likely to use Dennis' or Chris' answers). printf is a bit more complex to use than echo. Its first argument is a format string, in which escapes (like \n) are always interpreted; it can also contain format directives starting with %, which control where and how any additional arguments are included in it. Here are two different approaches to using it for a usage message:

First, you could include the entire message in the format string:

printf "usage: up [--level <n>| -n <levels>][--help][--version]\n\nReport bugs to: \nup home page: \n"

Note that unlike echo, you must include the final newline explicitly. Also, if the message happens to contain any % characters, they would have to be written as %%. If you wanted to include the bugreport and homepage addresses, they can be added quite naturally:

printf "usage: up [--level <n>| -n <levels>][--help][--version]\n\nReport bugs to: %s\nup home page: %s\n" "$bugreport" "$homepage"

Second, you could just use the format string to make it print each additional argument on a separate line:

printf "%s\n" "usage: up [--level <n>| -n <levels>][--help][--version]" "" "Report bugs to: " "up home page: "

With this option, adding the bugreport and homepage addresses is fairly obvious:

printf "%s\n" "usage: up [--level <n>| -n <levels>][--help][--version]" "" "Report bugs to: $bugreport" "up home page: $homepage"

I tried all the responses described here but my solution was changing inside my build.gradle file minSdkVersion from 8 to 9 because some libraries in my project can´t work with API 8, that´s was the reason for the message INSTALL_FAILED_OLDER_SDK:

apply plugin: 'com.android.application'

    android {
        compileSdkVersion 22
        buildToolsVersion "22.0.1"

        defaultConfig {
            applicationId "com.tuna.hello.androidstudioapplication"
            minSdkVersion 9
            targetSdkVersion 22
            versionCode 1
            versionName "1.0"
        }
...
...
...

If you prefer named parameters, it's possible (with a few tricks) to actually pass named parameters to functions (also makes it possible to pass arrays and references).

The method I developed allows you to define named parameters passed to a function like this:

function example { args : string firstName , string lastName , integer age } {
  echo "My name is ${firstName} ${lastName} and I am ${age} years old."
}

You can also annotate arguments as @required or @readonly, create ...rest arguments, create arrays from sequential arguments (using e.g. string[4]) and optionally list the arguments in multiple lines:

function example {
  args
    : @required string firstName
    : string lastName
    : integer age
    : string[] ...favoriteHobbies

  echo "My name is ${firstName} ${lastName} and I am ${age} years old."
  echo "My favorite hobbies include: ${favoriteHobbies[*]}"
}

In other words, not only you can call your parameters by their names (which makes up for a more readable core), you can actually pass arrays (and references to variables - this feature works only in Bash 4.3 though)! Plus, the mapped variables are all in the local scope, just as $1 (and others).

The code that makes this work is pretty light and works both in Bash 3 and Bash 4 (these are the only versions I've tested it with). If you're interested in more tricks like this that make developing with bash much nicer and easier, you can take a look at my Bash Infinity Framework, the code below is available as one of its functionalities.

to send a .NET / C# powershell eMail use such a structure:

for best behaviour create a class with a method like this

 using (PowerShell PowerShellInstance = PowerShell.Create())
            {
                PowerShellInstance.AddCommand("Send-MailMessage")
                                  .AddParameter("SMTPServer", "smtp.xxx.com")
                                  .AddParameter("From", "[email protected]")
                                  .AddParameter("Subject", "xxx Notification")
                                  .AddParameter("Body", body_msg)
                                  .AddParameter("BodyAsHtml")
                                  .AddParameter("To", recipients);

                // invoke execution on the pipeline (ignore output) --> nothing will be displayed
                PowerShellInstance.Invoke();
            }              

Whereby these instance is called in a function like:

        public void sendEMailPowerShell(string body_msg, string[] recipients)

Never forget to use a string array for the recepients, which can be look like this:

string[] reportRecipient = { 
                        "xxx <[email protected]>",
                        "xxx <[email protected]>"
                        };

body_msg

this message can be overgiven as parameter to the method itself, HTML coding enabled!!

recipients

never forget to use a string array in case of multiple recipients, otherwise only the last address in the string will be used!!!

calling the function can look like this:

        mail reportMail = new mail(); //instantiate from class
        reportMail.sendEMailPowerShell(reportMessage, reportRecipient); //msg + email addresses

ThumbUp

Not a big fan of the solutions provided (ie: multiple variables, helper classes, looping through 'possibly existing variables'). Below is a solution that instead uses an array as opposed to two separate variables. It's also easily extendable to handle multiple errors should you wish but for simplicity, I've kept it to one flash message:

Redirect with flash message array:

    return redirect('/admin/permissions')->with('flash_message', ['success','Updated Successfully','Permission "'. $permission->name .'" updated successfully!']);

Output based on array content:

@if(Session::has('flash_message'))
    <script type="text/javascript">
        jQuery(document).ready(function(){
            bootstrapNotify('{{session('flash_message')[0]}}','{{session('flash_message')[1]}}','{{session('flash_message')[2]}}');
        });
    </script>
@endif

Unrelated since you might have your own notification method/plugin - but just for clarity - bootstrapNotify is just to initiate bootstrap-notify from http://bootstrap-notify.remabledesigns.com/:

function bootstrapNotify(type,title = 'Notification',message) {
    switch (type) {
        case 'success':
            icon = "la-check-circle";
            break;
        case 'danger':
            icon = "la-times-circle";
            break;
        case 'warning':
            icon = "la-exclamation-circle";
    }

    $.notify({message: message, title : title, icon : "icon la "+ icon}, {type: type,allow_dismiss: true,newest_on_top: false,mouse_over: true,showProgressbar: false,spacing: 10,timer: 4000,placement: {from: "top",align: "right"},offset: {x: 30,y: 30},delay: 1000,z_index: 10000,animate: {enter: "animated bounce",exit: "animated fadeOut"}});
}

This method opens a file in the private data area of the application. You cannot open any files in subdirectories in this area or from entirely other areas using this method. So use the constructor of the FileInputStream directly to pass the path with a directory in it.

If you want to use a function form a package or module in python you have to import and reference them. For example normally you do the following to draw 5 points( [1,5],[2,4],[3,3],[4,2],[5,1]) in the space:

import matplotlib.pyplot
matplotlib.pyplot.plot([1,2,3,4,5],[5,4,3,2,1],"bx")
matplotlib.pyplot.show()

In your solution

from matplotlib import*

This imports the package matplotlib and "plot is not defined" means there is no plot function in matplotlib you can access directly, but instead if you import as

from matplotlib.pyplot import *
plot([1,2,3,4,5],[5,4,3,2,1],"bx")
show()

Now you can use any function in matplotlib.pyplot without referencing them with matplotlib.pyplot.

I would recommend you to name imports you have, in this case you can prevent disambiguation and future problems with the same function names. The last and clean version of above example looks like:

import matplotlib.pyplot as plt
plt.plot([1,2,3,4,5],[5,4,3,2,1],"bx")
plt.show()

What is the URL format used by jTDS?

The URL format for jTDS is:

jdbc:jtds:<server_type>://<server>[:<port>][/<database>][;<property>=<value>[;...]]

... domain Specifies the Windows domain to authenticate in. If present and the user name and password are provided, jTDS uses Windows (NTLM) authentication instead of the usual SQL Server authentication (i.e. the user and password provided are the domain user and password). This allows non-Windows clients to log in to servers which are only configured to accept Windows authentication.

If the domain parameter is present but no user name and password are provided, jTDS uses its native Single-Sign-On library and logs in with the logged Windows user's credentials (for this to work one would obviously need to be on Windows, logged into a domain, and also have the SSO library installed -- consult README.SSO in the distribution on how to do this).

You need to start creating the JAR at the root of the files.

So, for instance:

jar cvf program.jar -C path/to/classes .

That assumes that path/to/classes contains the com directory.

FYI, these days it is relatively uncommon for most people to use the jar command directly, as they will use a build tool such as Ant or Maven to take care of that (and other aspects of the build). It is well worth the effort of allowing one of those tools to take care of all aspects of your build, and it's even easier with a good IDE to help write the build.xml (Ant) or pom.xml (Maven).

.equals() doesn't perform an intelligent comparison for most classes unless the class overrides it. If it's not defined for a (user) class, it behaves the same as ==.

Reference: http://www.leepoint.net/notes-java/data/expressions/22compareobjects.html http://www.leepoint.net/data/expressions/22compareobjects.html

Here's another approach (assuming you have control of the HTML): add an empty <span></span> right after the input, and target that in CSS using input.mystyle + span:after

.field_with_errors {_x000D_
  display: inline;_x000D_
  color: red;_x000D_
}_x000D_
.field_with_errors input+span:after {_x000D_
  content: "*"_x000D_
}

<div class="field_with_errors">Label:</div>_x000D_
<div class="field_with_errors">_x000D_
  <input type="text" /><span></span> _x000D_
</div>

I'm using this approach in AngularJS because it will add .ng-invalid classes automatically to <input> form elements, and to the form, but not to the <label>.

The argument is of length zero takes places when you get an output as an integer of length 0 and not a NULL output.i.e., integer(0).

You can further verify my point by finding the class of your output- >class(output) "integer"

There actually IS a way to do this. Think about how you might use Newtonsoft JSON to deserialize an object from json. It will (or at least can) ignore missing elements and populate all the elements that it does know about.

So here's how I did it. A small code sample will follow my explanation.

1. Create an instance of your object from the base class and populate it accordingly.

2. Using the "jsonconvert" class of Newtonsoft json, serialize that object into a json string.

3. Now create your sub class object by deserializing with the json string created in step 2. This will create an instance of your sub class with all the properties of the base class.

This works like a charm! So.. when is this useful? Some people asked when this would make sense and suggested changing the OP's schema to accommodate the fact that you can't natively do this with class inheritance (in .Net).

In my case, I have a settings class that contains all the "base" settings for a service. Specific services have more options and those come from a different DB table, so those classes inherit the base class. They all have a different set of options. So when retrieving the data for a service, it's much easier to FIRST populate the values using an instance of the base object. One method to do this with a single DB query. Right after that, I create the sub class object using the method outlined above. I then make a second query and populate all the dynamic values on the sub class object.

The final output is a derived class with all the options set. Repeating this for additional new sub classes takes just a few lines of code. It's simple, and it uses a very tried and tested package (Newtonsoft) to make the magic work.

This example code is vb.Net, but you can easily convert to c#.

' First, create the base settings object.
    Dim basePMSettngs As gtmaPayMethodSettings = gtmaPayments.getBasePayMethodSetting(payTypeId, account_id)
    Dim basePMSettingsJson As String = JsonConvert.SerializeObject(basePMSettngs, Formatting.Indented)

    ' Create a pmSettings object of this specific type of payment and inherit from the base class object
    Dim pmSettings As gtmaPayMethodAimACHSettings = JsonConvert.DeserializeObject(Of gtmaPayMethodAimACHSettings)(basePMSettingsJson)

This query gets the columns name

SELECT COLUMN_NAME FROM INFORMATION_SCHEMA.Columns where TABLE_NAME = 'YourTableName'

And this one gets the count

SELECT Count(*) FROM INFORMATION_SCHEMA.Columns where TABLE_NAME = 'YourTableName'

Nope. Try the following:

List<string> _searchPatternList = new List<string>();
    ...
    List<string> fileList = new List<string>();
    foreach ( string ext in _searchPatternList )
    {
        foreach ( string subFile in Directory.GetFiles( folderName, ext  )
        {
            fileList.Add( subFile );
        }
    }

    // Sort alpabetically
    fileList.Sort();

    // Add files to the file browser control    
    foreach ( string fileName in fileList )
    {
        ...;
    }

ALTER TABLE allitems
CHANGE itemid itemid INT(10) AUTO_INCREMENT;

An alternative way you can do this, is using dictionary comprehension. This should be compatible with 2.7+

result = {
    key: value for key, value in
    {"foo": "bar", "lorem": None}.items()
    if value
}

Another clever way from that ancient thread:

int age = (
    Int32.Parse(DateTime.Today.ToString("yyyyMMdd")) - 
    Int32.Parse(birthday.ToString("yyyyMMdd"))) / 10000;

If you want to concatenate a variable with a fixed path and a string as the dynamic path into a whole path to remove the folder, you may need the following command:

$fixPath = "C:\Users\myUserName\Desktop"
Remove-Item ("$fixPath" + "\Folder\SubFolder") -Recurse

In the variable $newPath the concatenate path is now: "C:\Users\myUserName\Desktop\Folder\SubFolder"

So you can remove several directories from the starting point ("C:\Users\myUserName\Desktop"), which is already defined and fixed in the variable $fixPath.

$fixPath = "C:\Users\myUserName\Desktop"
Remote-Item ("$fixPath" + "\Folder\SubFolder") -Recurse
Remote-Item ("$fixPath" + "\Folder\SubFolder1") -Recurse
Remote-Item ("$fixPath" + "\Folder\SubFolder2") -Recurse

Answer for macOS 11 (Big Sur) in 2021

After installing Anaconda, run:

source /opt/anaconda3/bin/activate
conda init zsh

then close and reopen the Terminal window. The shell prompt should have a (base) prefix.

NOTE: I found many articles online saying to update the PATH variable, but Anaconda actually recommends against doing so and running the two commands above instead, which they state in their documentation.

For me it was solved in the following way with SQL Server Management studio -Log in as admin (I logged in as windows authentication) -Attach the mdf file (right click Database | attach | Add ) -Log out as admin -Log in as normal user

In case anyone needs a (nearly) ready-to-use PHP function, the following is based on this answer:

/**
 * Remove a column from a table.
 * 
 * @param string $tableName The table to remove the column from.
 * @param string $columnName The column to remove from the table.
 */
public function DropTableColumn($tableName, $columnName)
{
    // --
    // Determine all columns except the one to remove.

    $columnNames = array();

    $statement = $pdo->prepare("PRAGMA table_info($tableName);");
    $statement->execute(array());
    $rows = $statement->fetchAll(PDO::FETCH_OBJ);

    $hasColumn = false;

    foreach ($rows as $row)
    {
        if(strtolower($row->name) !== strtolower($columnName))
        {
            array_push($columnNames, $row->name);
        }
        else
        {
            $hasColumn = true;
        }
    }

    // Column does not exist in table, no need to do anything.
    if ( !$hasColumn ) return;

    // --
    // Actually execute the SQL.

    $columns = implode('`,`', $columnNames);

    $statement = $pdo->exec(
       "CREATE TABLE `t1_backup` AS SELECT `$columns` FROM `$tableName`;
        DROP TABLE `$tableName`;
        ALTER TABLE `t1_backup` RENAME TO `$tableName`;");
}

In contrast to other answers, the SQL used in this approach seems to preserve the data types of the columns, whereas something like the accepted answer seems to result in all columns to be of type TEXT.

Update 1:

The SQL used has the drawback that autoincrement columns are not preserved.

The chosen answer is outdated, same goes to meltingice /ajax-chosen plugin.

With Select2 plugin got many bugs which is i can't resolve it.

Here my answer for this question.

I integrated my solution with function trigger after user type. Thanks to this answer : https://stackoverflow.com/a/5926782/4319179.

//setup before functions
  var typingTimer;                //timer identifier
  var doneTypingInterval = 2000;  //time in ms (2 seconds)
  var selectID = 'YourSelectId';    //Hold select id
  var selectData = [];           // data for unique id array

  //on keyup, start the countdown
  $('#' + selectID + '_chosen .chosen-choices input').keyup(function(){

      // Change No Result Match text to Searching.
      $('#' + selectID + '_chosen .no-results').html('Searching = "'+ $('#' + selectID + '_chosen .chosen-choices input').val() + '"');


      clearTimeout(typingTimer);  //Refresh Timer on keyup 
      if ($('#' + selectID + '_chosen .chosen-choices input').val()) {

           typingTimer = setTimeout(doneTyping, doneTypingInterval);  //Set timer back if got value on input

      }

  });

  //user is "finished typing," do something
  function doneTyping () {

      var inputData = $('#' + selectID + '_chosen .chosen-choices input').val();  //get input data

      $.ajax({
        url: "YourUrl",
         data: {data: inputData},
        type:'POST',
        dataType: "json",
        beforeSend: function(){
          // Change No Result Match to Getting Data beforesend
          $('#' + selectID + '_chosen .no-results').html('Getting Data = "'+$('#' + selectID + '_chosen .chosen-choices input').val()+'"');
    },
        success: function( data ) { 

          // iterate data before append
          $.map( data, function( item ) {

            // matching data eg: by id or something unique; if data match: <option> not append - else: append <option>
            // This will prevent from select the same thing twice.
            if($.inArray(item.attr_hash,selectData) == -1){

              // if not match then append in select
              $('#' + selectID ).append('<option id="'+item.id+'" data-id = "'+item.id+'">' + item.data + '</option>');

            }            

          });

          // Update chosen again after append <option>
          $('#' + selectID ).trigger("chosen:updated");

        }
      });

  }

  // Chosen event listen on input change eg: after select data / deselect this function will be trigger
  $('#' + selectID ).on('change', function() {

    // get select jquery object
    var domArray = $('#' + selectID ).find('option:selected');

    // empty array data
    selectData = [];

    for (var i = 0, length = domArray.length; i < length; i++ ){

      // Push unique data to array (for matching purpose)
      selectData.push( $(domArray[i]).data('id') );

    }

    // Replace select <option> to only selected option
    $('#' + selectID ).html(domArray);

    // Update chosen again after replace selected <option>
    $('#' + selectID ).trigger("chosen:updated");

  });

First, convert the timespan to a string, then to DateTime, then back to a string:

Convert.ToDateTime(timespan.SelectedTime.ToString()).ToShortTimeString();

You can also specify columns on related model at the time of accessing it.

Post::first()->user()->get(['columns....']);

$('#my_select option:selected').attr('id');

You can also use partial from functools if you want to use a function that takes parameters but the function you are mocking does not. E.g. like this:

def mock_year(year):
    return datetime.datetime(year, 11, 28, tzinfo=timezone.utc)

@patch('django.utils.timezone.now', side_effect=partial(mock_year, year=2020))

This will return a callable that doesn't accept parameters (like Django's timezone.now()), but my mock_year function does.

You have included the dependency for sflj's api, but not the dependency for the implementation of the api, that is a separate jar, you could try slf4j-simple-1.6.1.jar.

In that case you don't want to insert size and color inside an array, but into an object

var options = { 
    'size': size,
    'color': color
  };

Afterwards you can access the sets of keys by

var keys = Object.keys( options );

I had a similar requirement, but I wanted the n'th item in a particular group. This is how I solved it.

groups = data.groupby(['group_key'])
selection = groups['index_col'].apply(lambda x: x % 3 == 0)
subset = data[selection]

You can use set with the /p argument:

SET /P variable=[promptString]

The /P switch allows you to set the value of a variable to a line of input entered by the user. Displays the specified promptString before reading the line of input. The promptString can be empty.

So, simply use something like

set /p Input=Enter some text: 

Later you can use that variable as argument to a command:

myCommand %Input%

Be careful though, that if your input might contain spaces it's probably a good idea to quote it:

myCommand "%Input%"

This is because you are reading a cursor, not an array. This means that you are reading sequentially through the results and when you get to the end you would need to reset the cursor to the beginning of the results to read them again.

If you did want to read over the results multiple times, you could use fetchAll to read the results into a true array and then it would work as you are expecting.

You want to do $arrayOfString[0].Title -eq $myPbiject.item(0).Title

-match is for regex matching ( the second argument is a regex )

For those without LINQ:

RadioButton GetCheckedRadio(Control container)
{
    foreach (var control in container.Controls)
    {
        RadioButton radio = control as RadioButton;

        if (radio != null && radio.Checked)
        {
            return radio;
        }
    }

    return null;
}

With C# 4.0, reflection isn't necessary as the DLR can call it using runtime types. Since using the DLR library is kind of a pain dynamically (instead of the C# compiler generating code for you), the open source framework Dynamitey (.net standard 1.5) gives you easy cached run-time access to the same calls the compiler would generate for you.

var name = InvokeMemberName.Create;
Dynamic.InvokeMemberAction(this, name("GenericMethod", new[]{myType}));


var staticContext = InvokeContext.CreateStatic;
Dynamic.InvokeMemberAction(staticContext(typeof(Sample)), name("StaticMethod", new[]{myType}));

As you described, you will need to use a different method based on different versions of iOS. If your team is using both Xcode 5 (which doesn't know about any iOS 8 selectors) and Xcode 6, then you will need to use conditional compiling as follows:

#if __IPHONE_OS_VERSION_MAX_ALLOWED >= 80000
if ([application respondsToSelector:@selector(registerUserNotificationSettings:)]) {
    // use registerUserNotificationSettings
} else {
    // use registerForRemoteNotificationTypes:
}
#else
// use registerForRemoteNotificationTypes:
#endif

If you are only using Xcode 6, you can stick with just this:

if ([application respondsToSelector:@selector(registerUserNotificationSettings:)]) {
    // use registerUserNotificationSettings
} else {
    // use registerForRemoteNotificationTypes:
}

The reason is here is that the way you get notification permissions has changed in iOS 8. A UserNotification is a message shown to the user, whether from remote or from local. You need to get permission to show one. This is described in the WWDC 2014 video "What's New in iOS Notifications"

Another method for checking equality regardless of value order works by using http://php.net/manual/en/function.array-intersect.php, like so:

$array1 = array(2,5,3);
$array2 = array(5,2,3);
if($array1 === array_intersect($array1, $array2) && $array2 === array_intersect($array2, $array1)) {
    echo 'Equal';
} else {
    echo 'Not equal';
}

Here's a version that works also with multidimensional arrays using http://php.net/manual/en/function.array-uintersect.php:

$array1 = array(
    array(5, 2),
    array(3, 6),
    array(2, 9, 4)
);
$array2 = array(
    array(3, 6),
    array(2, 9, 4),
    array(5, 2)
);

if($array1 === array_uintersect($array1, $array2, 'compare') && $array2 === array_uintersect($array2, $array1, 'compare')) {
    echo 'Equal';
} else {
    echo 'Not equal';
}

function compare($v1, $v2) {
    if ($v1===$v2) {
        return 0;
    }
    if ($v1 > $v2) return 1;
    return -1;
}

HTML5 introduces FormData class that can be used to file upload with ajax.

FormData support starts from following desktop browsers versions. IE 10+, Firefox 4.0+, Chrome 7+, Safari 5+, Opera 12+

FormData - Mozilla.org

If you want use margin, remove the class on every button and use :last-child CSS selector.

Html :

<div class="btn-toolbar text-center well">
    <button type="button" class="btn btn-primary btn-color btn-bg-color btn-sm col-xs-2">
      <span class="glyphicon glyphicon-plus" aria-hidden="true"></span> ADD PACKET
    </button>
    <button type="button" class="btn btn-primary btn-color btn-bg-color btn-sm col-xs-2">
      <span class="glyphicon glyphicon-edit" aria-hidden="true"></span> EDIT CUSTOMER
    </button>
    <button type="button" class="btn btn-primary btn-color btn-bg-color btn-sm col-xs-2">
      <span class="glyphicon glyphicon-time" aria-hidden="true"></span> HISTORY
    </button>
    <button type="button" class="btn btn-primary btn-color btn-bg-color btn-sm col-xs-2">
      <span class="glyphicon glyphicon-trash" aria-hidden="true"></span> DELETE CUSTOMER
    </button>
</div>

Css :

.btn-toolbar .btn{
    margin-right: 5px;
}
.btn-toolbar .btn:last-child{
    margin-right: 0;
}

I had the same error, but in Ubuntu 14.04 inside Windows 10 (Bash on Ubuntu on Windows). All I did to overcome the error was to update the Creators update, which then allowed me to install 16.04 version of Ubuntu bash and then after installing newest version of node (by this steps) I installed also the newest version of npm and then the nodemon started to work properly.

I personally find it easier use MySQL event scheduler than cron.

Enable it with

SET GLOBAL event_scheduler = ON;

and create an event like this:

CREATE EVENT name_of_event
ON SCHEDULE EVERY 1 DAY
STARTS '2014-01-18 00:00:00'
DO
DELETE FROM tbl_message WHERE DATEDIFF( NOW( ) ,  timestamp ) >=7;

and that's it.

Read more about the syntax here and here is more general information about it.

You need to set android:exported="true" in your AndroidManifest.xml file where you declare this Activity:

<activity
    android:name="com.example.lib.MainActivity"
    android:label="LibMain" 
    android:exported="true">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" >
        </action>
    </intent-filter>
</activity>

This got me the value and text of the selected options for the jQuery multiselect.js plugin:

$("#selectBox").multiSelect({
    afterSelect: function(){
        var selections = [];
        $("#selectBox option:selected").each(function(){
            var optionValue = $(this).val();
            var optionText = $(this).text();
            console.log("optionText",optionText);                
            // collect all values
            selections.push(optionValue);
        });

        // use array "selections" here.. 
    }
});   

very usefull if you need it for your "onChange" event ;)

Look at the following example, from the HTML5 specification about aside.

It makes clear that what currently is recommended (October 2012) it is to group widgets inside aside elements. Then, each widget is whatever best represents it, a nav, a serie of blockquotes, etc

The following extract shows how aside can be used for blogrolls and other side content on a blog:

<body>
 <header>
  <h1>My wonderful blog</h1>
  <p>My tagline</p>
 </header>
 <aside>
  <!-- this aside contains two sections that are tangentially related
  to the page, namely, links to other blogs, and links to blog posts
  from this blog -->
  <nav>
   <h1>My blogroll</h1>
   <ul>
    <li><a href="http://blog.example.com/">Example Blog</a>
   </ul>
  </nav>
  <nav>
   <h1>Archives</h1>
   <ol reversed>
    <li><a href="/last-post">My last post</a>
    <li><a href="/first-post">My first post</a>
   </ol>
  </nav>
 </aside>
 <aside>
  <!-- this aside is tangentially related to the page also, it
  contains twitter messages from the blog author -->
  <h1>Twitter Feed</h1>

Looks like you might want the ISO format so that you can retain the timezone.

var dateTime = new Date(1370001284000);
dateTime.toISOString(); // Returns "2013-05-31T11:54:44.000Z"

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toISOString

Simply use map function:

var arrOfObj = arrOfObj.map(function(element){
   element.active = true;
   return element;
}

Map is pretty decent on compatibility: you can be reasonably safe from IE <= 9.

However, if you are 100% sure your users will use ES6 Compatible browser, you can shorten that function with arrow functions, as @Sergey Panfilov has suggested.

This is bit tricky

Now a days most of website new techniques to save websites from scraping

1st Technique

Ctrl+U this will show you Page Source

2nd Technique

This one is small hack if the website has ajax like functionality.

Just Hover the mouse key on inspect element untill whole screen becomes just right click then and copy element

That's it you are good to go.

Add the s modifier to your regex to cause . to match newlines:

$string =~ /(START)(.+?)(END)/s;

Try this:

SET TERMOUT OFF; 
spool M:\Documents\test;
select * from employees;
/
spool off;

I see this question is a bit old, but I decided to give an answer anyway for those who find this question by searching.
The standard way to represent 2D/3D transformations nowadays is by using homogeneous coordinates. [x,y,w] for 2D, and [x,y,z,w] for 3D. Since you have three axes in 3D as well as translation, that information fits perfectly in a 4x4 transformation matrix. I will use column-major matrix notation in this explanation. All matrices are 4x4 unless noted otherwise.
The stages from 3D points and to a rasterized point, line or polygon looks like this:

1. Transform your 3D points with the inverse camera matrix, followed with whatever transformations they need. If you have surface normals, transform them as well but with w set to zero, as you don't want to translate normals. The matrix you transform normals with must be isotropic; scaling and shearing makes the normals malformed.
2. Transform the point with a clip space matrix. This matrix scales x and y with the field-of-view and aspect ratio, scales z by the near and far clipping planes, and plugs the 'old' z into w. After the transformation, you should divide x, y and z by w. This is called the perspective divide.
3. Now your vertices are in clip space, and you want to perform clipping so you don't render any pixels outside the viewport bounds. Sutherland-Hodgeman clipping is the most widespread clipping algorithm in use.
4. Transform x and y with respect to w and the half-width and half-height. Your x and y coordinates are now in viewport coordinates. w is discarded, but 1/w and z is usually saved because 1/w is required to do perspective-correct interpolation across the polygon surface, and z is stored in the z-buffer and used for depth testing.

This stage is the actual projection, because z isn't used as a component in the position any more.

The algorithms:

Calculation of field-of-view

This calculates the field-of view. Whether tan takes radians or degrees is irrelevant, but angle must match. Notice that the result reaches infinity as angle nears 180 degrees. This is a singularity, as it is impossible to have a focal point that wide. If you want numerical stability, keep angle less or equal to 179 degrees.

fov = 1.0 / tan(angle/2.0)

Also notice that 1.0 / tan(45) = 1. Someone else here suggested to just divide by z. The result here is clear. You would get a 90 degree FOV and an aspect ratio of 1:1. Using homogeneous coordinates like this has several other advantages as well; we can for example perform clipping against the near and far planes without treating it as a special case.

Calculation of the clip matrix

This is the layout of the clip matrix. aspectRatio is Width/Height. So the FOV for the x component is scaled based on FOV for y. Far and near are coefficients which are the distances for the near and far clipping planes.

[fov * aspectRatio][        0        ][        0              ][        0       ]
[        0        ][       fov       ][        0              ][        0       ]
[        0        ][        0        ][(far+near)/(far-near)  ][        1       ]
[        0        ][        0        ][(2*near*far)/(near-far)][        0       ]

Screen Projection

After clipping, this is the final transformation to get our screen coordinates.

new_x = (x * Width ) / (2.0 * w) + halfWidth;
new_y = (y * Height) / (2.0 * w) + halfHeight;

If you still ponder about this, the OpenGL specification is a really nice reference for the maths involved. The DevMaster forums at http://www.devmaster.net/ have a lot of nice articles related to software rasterizers as well.

If you ever need to delete all the indexes, this may come in handy:

curl -X DELETE 'http://localhost:9200/_all'

Powershell:

Invoke-WebRequest -method DELETE http://localhost:9200/_all

The first parameter of Html.RadioButtonFor() should be the property name you're using, and the second parameter should be the value of that specific radio button. Then they'll have the same name attribute value and the helper will select the given radio button when/if it matches the property value.

Example:

<div class="editor-field">
    <%= Html.RadioButtonFor(m => m.Gender, "M" ) %> Male
    <%= Html.RadioButtonFor(m => m.Gender, "F" ) %> Female
</div>

Here's a more specific example:

I made a quick MVC project named "DeleteMeQuestion" (DeleteMe prefix so I know that I can remove it later after I forget about it).

I made the following model:

namespace DeleteMeQuestion.Models
{
    public class QuizModel
    {
        public int ParentQuestionId { get; set; }
        public int QuestionId { get; set; }
        public string QuestionDisplayText { get; set; }
        public List<Response> Responses { get; set; }

        [Range(1,999, ErrorMessage = "Please choose a response.")]
        public int SelectedResponse { get; set; }
    }

    public class Response
    {
        public int ResponseId { get; set; }
        public int ChildQuestionId { get; set; }
        public string ResponseDisplayText { get; set; }
    }
}

There's a simple range validator in the model, just for fun. Next up, I made the following controller:

namespace DeleteMeQuestion.Controllers
{
    [HandleError]
    public class HomeController : Controller
    {
        public ActionResult Index(int? id)
        {
            // TODO: get question to show based on method parameter 
            var model = GetModel(id);
            return View(model);
        }

        [HttpPost]
        public ActionResult Index(int? id, QuizModel model)
        {
            if (!ModelState.IsValid)
            {
                var freshModel = GetModel(id);
                return View(freshModel);
            }

            // TODO: save selected answer in database
            // TODO: get next question based on selected answer (hard coded to 999 for now)

            var nextQuestionId = 999;
            return RedirectToAction("Index", "Home", new {id = nextQuestionId});
        }

        private QuizModel GetModel(int? questionId)
        {
            // just a stub, in lieu of a database

            var model = new QuizModel
            {
                QuestionDisplayText = questionId.HasValue ? "And so on..." : "What is your favorite color?",
                QuestionId = 1,
                Responses = new List<Response>
                                                {
                                                    new Response
                                                        {
                                                            ChildQuestionId = 2,
                                                            ResponseId = 1,
                                                            ResponseDisplayText = "Red"
                                                        },
                                                    new Response
                                                        {
                                                            ChildQuestionId = 3,
                                                            ResponseId = 2,
                                                            ResponseDisplayText = "Blue"
                                                        },
                                                    new Response
                                                        {
                                                            ChildQuestionId = 4,
                                                            ResponseId = 3,
                                                            ResponseDisplayText = "Green"
                                                        },
                                                }
            };

            return model;
        }
    }
}

Finally, I made the following view that makes use of the model:

<%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<DeleteMeQuestion.Models.QuizModel>" %>

<asp:Content ContentPlaceHolderID="TitleContent" runat="server">
    Home Page
</asp:Content>

<asp:Content ContentPlaceHolderID="MainContent" runat="server">

    <% using (Html.BeginForm()) { %>

        <div>

            <h1><%: Model.QuestionDisplayText %></h1>

            <div>
            <ul>
            <% foreach (var item in Model.Responses) { %>
                <li>
                    <%= Html.RadioButtonFor(m => m.SelectedResponse, item.ResponseId, new {id="Response" + item.ResponseId}) %>
                    <label for="Response<%: item.ResponseId %>"><%: item.ResponseDisplayText %></label>
                </li>
            <% } %>
            </ul>

            <%= Html.ValidationMessageFor(m => m.SelectedResponse) %>

        </div>

        <input type="submit" value="Submit" />

    <% } %>

</asp:Content>

As I understand your context, you have questions with a list of available answers. Each answer will dictate the next question. Hopefully that makes sense from my model and TODO comments.

This gives you the radio buttons with the same name attribute, but different ID attributes.

In ASP.NET Core MVC the solution is to add a using in _ViewImports.cshtml, instead of putting it web.config in the View folder when working with ASP.NET MVC 5.

_ViewImports.cshtml

@using mySolution
@using mySolution.ViewModels // <-- Add this, and place your ViewModel (e.g. LoginViewModel) in here.
@addTagHelper *, Microsoft.AspNetCore.Mvc.TagHelpers

View

@model LoginViewModel // Add to _ViewImports to make this line work
<div>This is the View for the login screen.</div>

Try this one.

SELECT Employee.emp_id, Employee.emp_name,Manager.emp_id as Mgr_Id, Manager.emp_name as Mgr_Name 
FROM tblEmployeeDetails Employee 
LEFT JOIN tblEmployeeDetails Manager ON Employee.emp_mgr_id = Manager.emp_id

Have you used another UI thread? You shouldn't use more than 1 UI thread and make it look like a sandwich. Doing this will cause memory leaks.

I have solved a similar issue 2 days ago...

To keep things short: The main thread can have many UI threads to do multiple works, but if one sub-thread containing a UI thread is inside it, The UI thread may not have finished its work yet while it's parent thread has already finished its work, this causes memory leaks.

For example...for Fragment & UI application...this will cause memory leaks.

getActivity().runOnUiThread(new Runnable(){

   public void run() {//No.1

  ShowDataScreen();

getActivity().runOnUiThread(new Runnable(){

    public void run() {//No.2

Toast.makeText(getActivity(), "This is error way",Toast.LENGTH_SHORT).show();

    }});// end of No.2 UI new thread

}});// end of No.1 UI new thread

My solution is rearrange as below:

getActivity().runOnUiThread(new Runnable(){

   public void run() {//No.1

ShowDataScreen();

}});// end of No.1 UI new thread        

getActivity().runOnUiThread(new Runnable(){

   public void run() {//No.2

Toast.makeText(getActivity(), "This is correct way",Toast.LENGTH_SHORT).show();

}});// end of No.2 UI new thread

for you reference.

I am Taiwanese, I am glad to answer here once more.

To add to advice already given, if you have a web app running through IIS that uses the DB, you may also need to stop (not recycle) the app pool for the app while you restore, then re-start. Stopping the app pool kills off active http connections and doesn't allow any more, which could otherwise end up allowing processes to be triggered that connect to and thereby lock the database. This is a known issue for example with the Umbraco Content Management System when restoring its database

In your eclipse.ini file simply put

   }
catch (Exception ex){
       //do something

This is how I got 1.7 to work with Eclipse. I hope it helps.

1. I Downloaded the latest OpenJDK 1.7 universal (32/64 bits) JDK from Mac OS/X branch from http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html
2. copied the jdk to /Library/Java/JavaVirtualMachines/ next to the default 1.6.0 one
3. In Eclipse > Preferences > Java > Installed JREs you add a new one, of type MacOS X VM, and set the home as /Library/Java/JavaVirtualMachines/1.7.0.jdk/Contents/Home and name Java SE 7 (OpenJDK)
4. Click Finish
5. Set the added JRE as default

that should be it :)

df <- data.frame(b = c(1, 1, 1), c = c(2, 2, 2), d = c(3, 3, 3))
df
##   b c d
## 1 1 2 3
## 2 1 2 3
## 3 1 2 3

df <- data.frame(a = c(0, 0, 0), df)
df
##   a b c d
## 1 0 1 2 3
## 2 0 1 2 3
## 3 0 1 2 3

What you want to do is called "serialization". There are several ways of doing it, but if you don't need anything fancy I think using the standard Java object serialization would do just fine.

Perhaps you could use something like this?

package com.example;

import java.io.ByteArrayInputStream;
import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;

public class Serializer {

    public static byte[] serialize(Object obj) throws IOException {
        try(ByteArrayOutputStream b = new ByteArrayOutputStream()){
            try(ObjectOutputStream o = new ObjectOutputStream(b)){
                o.writeObject(obj);
            }
            return b.toByteArray();
        }
    }

    public static Object deserialize(byte[] bytes) throws IOException, ClassNotFoundException {
        try(ByteArrayInputStream b = new ByteArrayInputStream(bytes)){
            try(ObjectInputStream o = new ObjectInputStream(b)){
                return o.readObject();
            }
        }
    }

}

There are several improvements to this that can be done. Not in the least the fact that you can only read/write one object per byte array, which might or might not be what you want.

Note that "Only objects that support the java.io.Serializable interface can be written to streams" (see java.io.ObjectOutputStream).

Since you might run into it, the continuous allocation and resizing of the java.io.ByteArrayOutputStream might turn out to be quite the bottle neck. Depending on your threading model you might want to consider reusing some of the objects.

For serialization of objects that do not implement the Serializable interface you either need to write your own serializer, for example using the read*/write* methods of java.io.DataOutputStream and the get*/put* methods of java.nio.ByteBuffer perhaps together with reflection, or pull in a third party dependency.

This site has a list and performance comparison of some serialization frameworks. Looking at the APIs it seems Kryo might fit what you need.

This is a MySQL-specific answer, not sure where else it works --

You can create an empty table having the same column definitions with:

CREATE TEMPORARY TABLE temp_foo LIKE foo;

And you can create a populated copy of an existing table with:

CREATE TEMPORARY TABLE temp_foo SELECT * FROM foo;

And the following works in postgres; unfortunately the different RDBMS's don't seem very consistent here:

CREATE TEMPORARY TABLE temp_foo AS SELECT * FROM foo;

The most simple way to do it without using javascript is using required=""

<input type="text" ID="txtName"  Width="165px" required=""/>

The backslash (\) is an escape character in Javascript (along with a lot of other C-like languages). This means that when Javascript encounters a backslash, it tries to escape the following character. For instance, \n is a newline character (rather than a backslash followed by the letter n).

In order to output a literal backslash, you need to escape it. That means \\ will output a single backslash (and \\\\ will output two, and so on). The reason "aa ///\" doesn't work is because the backslash escapes the " (which will print a literal quote), and thus your string is not properly terminated. Similarly, "aa ///\\\" won't work, because the last backslash again escapes the quote.

Just remember, for each backslash you want to output, you need to give Javascript two.

I faced this same issue. I believe it happens when you have foreign keys to larger tables (which takes time).

I tried to run the create table statement again without the foreign key declarations and found it worked.

Then after creating the table, I added the foreign key constrains using ALTER TABLE query.

Hope this will help someone.

It's also good note that outline: none can be applied to both <button> tags and input[type=button] to remove the browser-applied border on click.

Um...

with open(os.path.join(src_dir, f)) as fin:

Also, you never output to a new file.

I dont think you need to use jQuery at all, just simple JavaScript...

Save the date as a string:

dte = fecha.value;//2014-01-06

Split the string to get the day, month & year values...

dteSplit = dte.split("-");
yr = dteSplit[0][2] + dteSplit[0][3]; //special yr format, take last 2 digits
month = dteSplit[1];
day = dteSplit[2];

Rejoin into final date string:

finalDate = month+"-"+day+"-"+year

There is an article in MSDN which describes the differences:

Comparing Web Site Projects and Web Application Projects

BTW: there are some similar questions about that topic, e.g:

• Web Site vs. ASP.Net Web Application in Visual Studio note: was removed, no longer on SO
• website or webapplication in.ASP.NET

If this isn't made obvious by the the previous answers:

:bd will close the current buffer. If you don't want to grab the buffer list.

You can do it as follow:

#include < iostream >

using namespace std;

int main () {

   string texts[] = {"Apple", "Banana", "Orange"};

   for( unsigned int a = 0; a < sizeof(texts) / 32; a++ ) { // 32 is the size of string data type

       cout << "value of a: " << texts[a] << endl;

   }


   return 0;

}

It should be document.getElementById("txtresult").value= result;

You are setting the value of the textbox to the result. The id="txtresult" is not an HTML element.

Just to update Gabe Sechan's answer. If your manifest asks for permissions to READ_CALL_LOG and READ_PHONE_STATE, onReceive will called TWICE. One of which has EXTRA_INCOMING_NUMBER in it and the other doesn't. You have to test which has it and it can occur in any order.

Probably the best way is to use Guava

List<String> list = new ArrayList<String>();
list.add("How are you");
list.add("How you doing");
list.add("Joe");
list.add("Mike");
    
Collection<String> filtered = Collections2.filter(list,
    Predicates.containsPattern("How"));
print(filtered);

prints

How are you
How you doing

In case you want to get the filtered collection as a list, you can use this (also from Guava):

List<String> filteredList = Lists.newArrayList(Collections2.filter(
    list, Predicates.containsPattern("How")));

I have used both timers and Thread.Sleep(x), or either, depending on the situation.

If I have a short piece of code that needs to run repeadedly, I probably use a timer.

If I have a piece of code that might take longer to run than the delay timer (such as retrieving files from a remote server via FTP, where I don't control or know the network delay or file sizes / count), I will wait for a fixed period of time between cycles.

Both are valid, but as pointed out earlier they do different things. The timer runs your code every x milliseconds, even if the previous instance hasn't finished. The Thread.Sleep(x) waits for a period of time after completing each iteration, so the total delay per loop will always be longer (perhaps not by much) than the sleep period.

Try this It is working for me..

The syntax is GetFiles(string path, string searchPattern);

var filePath = Server.MapPath("~/App_Data/");
string[] filePaths = Directory.GetFiles(@filePath, "*.*");

This code will return all the files inside App_Data folder.

The second parameter . indicates the searchPattern with File Extension where the first * is for file name and second is for format of the file or File Extension like (*.png - any file name with .png format.

a simple way would be to cast the dates into timestamps and take their difference and then extract the DAY part.

if you want real difference

select extract(day from 'DATE_A'::timestamp - 'DATE_B':timestamp);

if you want absolute difference

select abs(extract(day from 'DATE_A'::timestamp - 'DATE_B':timestamp));

Here is a list of all http-headers: http://en.wikipedia.org/wiki/List_of_HTTP_header_fields

And here is a list of all apache-logformats: http://httpd.apache.org/docs/2.0/mod/mod_log_config.html#formats

As you did write correctly, the code for logging a specific header is %{foobar}i where foobar is the name of the header. So, the only solution is to create a specific format string. When you expect a non-standard header like x-my-nonstandard-header, then use %{x-my-nonstandard-header}i. If your server is going to ignore this non-standard-header, why should you want to write it to your logfile? An unknown header has absolutely no effect to your system.

In MonoTouch:

To get the Major version use:

UIDevice.CurrentDevice.SystemVersion.Split('.')[0]

For minor version use:

UIDevice.CurrentDevice.SystemVersion.Split('.')[1]

You can use the split() function to break input on the basis of line break.

yourString.split("\n")

Maybe you should use DENSE_RANK.

SELECT *
FROM (
       SELECT
         [Salary],
         (DENSE_RANK()
         OVER
         (
           ORDER BY [Salary] DESC)) AS rnk
       FROM [Table1]
       GROUP BY [Num]
     ) AS A
WHERE A.rnk = 2

You should type this command with flag -f (force):

sudo docker volume rm -f <VOLUME NAME>

This should work for SQL Server:

SELECT * FROM myTable
WHERE month = DATEPART(m, GETDATE()) AND
year = DATEPART(yyyy, GETDATE())

git clone --filter from Git 2.19

This option will actually skip fetching most unneeded objects from the server:

git clone --depth 1 --no-checkout --filter=blob:none \
  "file://$(pwd)/server_repo" local_repo
cd local_repo
git checkout master -- mydir/myfile

The server should be configured with:

git config --local uploadpack.allowfilter 1
git config --local uploadpack.allowanysha1inwant 1

There is no server support as of v2.19.0, but it can already be locally tested.

TODO: --filter=blob:none skips all blobs, but still fetches all tree objects. But on a normal repo, this should be tiny compared to the files themselves, so this is already good enough. Asked at: https://www.spinics.net/lists/git/msg342006.html Devs replied a --filter=tree:0 is in the works to do that.

Remember that --depth 1 already implies --single-branch, see also: How do I clone a single branch in Git?

file://$(path) is required to overcome git clone protocol shenanigans: How to shallow clone a local git repository with a relative path?

The format of --filter is documented on man git-rev-list.

An extension was made to the Git remote protocol to support this feature.

Conclusions: all blobs except d1/a are missing. E.g. f70a17f51b7b30fec48a32e4f19ac15e261fd1a4, which is d1/b, is not there after checking out d1/.

Note that root/root and mybranch/mybranch are also missing, but --depth 1 hides that from the list of missing files. If you remove --depth 1, then they show on the list of missing files.

For the selected value: $(this).val()

If you need the selected option element, $("option:selected", this)

.NET 4.0 edit

Since .NET 4.0, it is possible to access a single line of a file directly. For instance, to access line 15:

string line = File.ReadLines(FileName).Skip(14).Take(1).First();

This will return only the line required

Since you can't predict the location (can you?) of the i-th line in the file, you'll have to read all previous lines too. If the line number is small, this can be more efficient than the ReadAllLines method.

string GetLine(string fileName, int line)
{
   using (var sr = new StreamReader(fileName)) {
       for (int i = 1; i < line; i++)
          sr.ReadLine();
       return sr.ReadLine();
   }
}

source URL for image can be a URL on a website like http://www.google.co.il/images/srpr/nav_logo73.png or https://https.openbsd.org/images/tshirt-26_front.gif or if you want to use a local file try this: url("file:///MacintoshHDOriginal/Users/lowri/Desktop/acgnx/image s/images/acgn-site-background-X_07.jpg")

What is "it" in the statement "it just says the procedure is completed"?

By default, most tools do not configure a buffer for dbms_output to write to and do not attempt to read from that buffer after code executes. Most tools, on the other hand, have the ability to do so. In SQL*Plus, you'd need to use the command set serveroutput on [size N|unlimited]. So you'd do something like

SQL> set serveroutput on size 30000;
SQL> exec print_actor_quotes( <<some value>> );

In SQL Developer, you'd go to View | DBMS Output to enable the DBMS Output window, then push the green plus icon to enable DBMS Output for a particular session.

Additionally, assuming that you don't want to print the literal "a.firstNamea.lastName" for every row, you probably want

FOR row IN quote_recs
LOOP
  DBMS_OUTPUT.PUT_LINE( row.firstName || ' ' || row.lastName );
END LOOP;

May it will help for u. U should use (localdb).

I have faced the same problem when I tape the URL

https://www.nameDomain.com/phpmyadmin

the forbidden message shows up, because of the rules on /use/share/phpMyAdmin directory I fix it by adding in this file /etc/httpd/conf.d/phpMyAdmin.conf in this section

<Directory /usr/share/phpMyAdmin/>
    ....
</Directory>

these line of rules

<Directory /usr/share/phpMyAdmin/>
   Order Deny,Allow
   Deny from All
   Allow from 127.0.0.1
   Allow from ::1
   Allow from All
   ...
</Directory>

you save the file, then you restart the apache service whatever method you choose service httpd graceful or service httpd restart it depends on your policy

for security reasons you can specify one connection by setting one IP address if your IP does not change, else if your IP changes every time you have to change it also.

<Directory /usr/share/phpMyAdmin/>
   Order Deny,Allow
   Deny from All
   Allow from 127.0.0.1
   Allow from ::1
   Allow from 105.105.105.254 ## set here your IP address
   ...
</Directory>

For the complete list of attributes, the short answer is: no. The problem is that the attributes are actually defined as the arguments accepted by the getattr built-in function. As the user can reimplement __getattr__, suddenly allowing any kind of attribute, there is no possible generic way to generate that list. The dir function returns the keys in the __dict__ attribute, i.e. all the attributes accessible if the __getattr__ method is not reimplemented.

For the second question, it does not really make sense. Actually, methods are callable attributes, nothing more. You could though filter callable attributes, and, using the inspect module determine the class methods, methods or functions.

If want to remove the word from only the start of the string, then you could do:

  string[string.startswith(prefix) and len(prefix):]  

Where string is your string variable and prefix is the prefix you want to remove from your string variable.

For example:

  >>> papa = "papa is a good man. papa is the best."  
  >>> prefix = 'papa'
  >>> papa[papa.startswith(prefix) and len(prefix):]
  ' is a good man. papa is the best.'

In your .button CSS, try display:inline-block. See this JSFiddle

if you had only one field to "DISTINCT", you could use:

SELECT COUNT(DISTINCT DocumentId) 
FROM DocumentOutputItems

and that does return the same query plan as the original, as tested with SET SHOWPLAN_ALL ON. However you are using two fields so you could try something crazy like:

    SELECT COUNT(DISTINCT convert(varchar(15),DocumentId)+'|~|'+convert(varchar(15), DocumentSessionId)) 
    FROM DocumentOutputItems

but you'll have issues if NULLs are involved. I'd just stick with the original query.

This is a useful article which graphically shows the explanation of the reset command.

https://git-scm.com/docs/git-reset

Reset --hard can be quite dangerous as it overwrites your working copy without checking, so if you haven't commited the file at all, it is gone.

As for Source tree, there is no way I know of to undo commits. It would most likely use reset under the covers anyway

Under Basic settings:

1. Add the platform - Mine was web.
2. Supply the site URL - mind the http or https.
3. You can also supply the mobile site URL if you have any - remember to mind the http or https here as well.
4. Save the changes.

Then hit the advanced tab and scroll down to locate Valid OAuth redirect URIs its right below Client Token.

1. Supply the redirection URL - The URL to redirect to after the login.
2. Save the changes.

Then get back to your website or web page and refresh.

Input a character from its hexadecimal value (insert mode):

In a talk about core containers internals in Python at PyCon 2012, Raymond Hettinger is suggesting to use [None] * n to pre-allocate the length you want.

Slides available as PPT or via Google

The whole slide deck is quite interesting. The presentation is available on YouTube, but it doesn't add much to the slides.

This is old and my problem ended up being related to the problem but not for the OP but my solution is for anyone else who tried the above to no avail.

I had a setting in a modified version of Django to minify CSS and JS files that only ran when DEBUG was off. My server did not have the CSS minifier installed and threw the error. If you are using Django-Mako-Plus, this might be your issue.

simple way to do this in one line of code would be this

string sub = input.Substring(input.Length > 5 ? input.Length - 5 : 0);

and here some informations about Operator ? :

usage of memalign, Aligned-Memory-Blocks might be a good solution for the problem.

Sohnee solutions is cleaner, but you can also try

window["bootbox"]

grab the second child:

$(t).children().eq(1);

or, grab the second child <td>:

$(t).children('td').eq(1);

See documentation for children and eq.

In simple format

   $curMonth = date('F');
   $curYear  = date('Y');
   $timestamp    = strtotime($curMonth.' '.$curYear);
   $first_second = date('Y-m-01 00:00:00', $timestamp);
   $last_second  = date('Y-m-t 12:59:59', $timestamp); 

For next month change $curMonth to $curMonth = date('F',strtotime("+1 months"));

You should include the repository where you want to deploy in the distribution management section of the pom.xml.

Example:

<project xmlns="http://maven.apache.org/POM/4.0.0"   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"   xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
                      http://maven.apache.org/xsd/maven-4.0.0.xsd">
...   
<distributionManagement>
    <repository>
      <uniqueVersion>false</uniqueVersion>
      <id>corp1</id>
      <name>Corporate Repository</name>
      <url>scp://repo/maven2</url>
      <layout>default</layout>
    </repository>
    ...
</distributionManagement>
...
</project>

See Distribution Management

The Problem is how you access row

Specifically row["waocs"] and row["pool_number"] of ocs[row["pool_number"]]=int(row["waocs"])

If you look up the official-documentation of fetchall() you find.

The method fetches all (or all remaining) rows of a query result set and returns a list of tuples.

Therefore you have to access the values of rows with row[__integer__] like row[0]

Try this:

$.grep(array, function(element) {

})

To exclude all type of stop-words including nltk stop-words, you could do something like this:

from stop_words import get_stop_words
from nltk.corpus import stopwords

stop_words = list(get_stop_words('en'))         #About 900 stopwords
nltk_words = list(stopwords.words('english')) #About 150 stopwords
stop_words.extend(nltk_words)

output = [w for w in word_list if not w in stop_words]

I had a different scenario, but still landed on this answer.
I had imported my root project folder containing multiple Maven projects but also some other stuff used in this project.
IntelliJ recognised the Java files, but didn't resolve the Maven dependencies.

I fixed this by performing a right-click on each pom and then "Add as maven project"

First of all go to the /home directorty then open invisible shell script with some text editor, ~/.bash_profile (macOS) or ~/.bashrc (linux) go to the bottom, you would see something like this,

export LD_LIBRARY_PATH = /usr/local/lib

change this like that( remove blank point around the = ),

export LD_LIBRARY_PATH=/usr/local/lib

it should be useful.

You didn't publish your code, and I suspect you do something wrong. it is possible to change the size by assigning width and height attributes using numbers:

canvasNode.width  = 200; // in pixels
canvasNode.height = 100; // in pixels

At least it works for me. Make sure you don't assign strings (e.g., "2cm", "3in", or "2.5px"), and don't mess with styles.

Actually this is a publicly available knowledge — you can read all about it in the HTML canvas spec — it is very small and unusually informative. This is the whole DOM interface:

interface HTMLCanvasElement : HTMLElement {
           attribute unsigned long width;
           attribute unsigned long height;

  DOMString toDataURL();
  DOMString toDataURL(in DOMString type, [Variadic] in any args);

  DOMObject getContext(in DOMString contextId);
};

As you can see it defines 2 attributes width and height, and both of them are unsigned long.

This is my basic understanding. It may well be wrong!

1. Items are watched by passing a function (returning the thing to be watched) to the $watch method.
2. Changes to watched items must be made within a block of code wrapped by the $apply method.
3. At the end of the $apply the $digest method is invoked which goes through each of the watches and checks to see if they changed since last time the $digest ran.
4. If any changes are found then the digest is invoked again until all changes stabilize.

In normal development, data-binding syntax in the HTML tells the AngularJS compiler to create the watches for you and controller methods are run inside $apply already. So to the application developer it is all transparent.

I'm not sure, but you may be able to just use

$("#filecontainer #choose_pic").click(function() {
    // do something here
});

Either that or you could just add a <script> tag into the iframe (if you have access to the code inside), and then use window.parent.DoSomething() in the frame, with the code

function DoSomething() {
    // do something here
}

in the parent. If none of those work, try window.postMessage. Here is some info on that.

Using jQuery

I would create a button and an invisible input like so:

<button id="button">Open</button>
<input id="file-input" type="file" name="name" style="display: none;" />

and add some jQuery to trigger it:

$('#button').on('click', function() {
    $('#file-input').trigger('click');
});

Using Vanilla JS

Same idea, without jQuery (credits to @Pascale):

<button onclick="document.getElementById('file-input').click();">Open</button>
<input id="file-input" type="file" name="name" style="display: none;" />

For me, no combination of window.requestAnimationFrame or setTimeout produced consistent results. Sometimes it worked, but not always—or sometimes it would be too late.

I fixed it by looping window.requestAnimationFrame as many times as necessary.
(Typically 0 or 2-3 times)

The key is diff > 0: here we can ensure exactly when the page updates.

// Ensure new image was loaded before scrolling
if (oldH > 0 && images.length > prevState.images.length) {
    (function scroll() {
        const newH = ref.scrollHeight;
        const diff = newH - oldH;

        if (diff > 0) {
            const newPos = top + diff;
            window.scrollTo(0, newPos);
        } else {
            window.requestAnimationFrame(scroll);
        }
    }());
}

>>> import requests
>>> response = requests.get('https://website.com/id', headers={'Authorization': 'access_token myToken'})

If the above doesnt work , try this:

>>> import requests
>>> response = requests.get('https://api.buildkite.com/v2/organizations/orgName/pipelines/pipelineName/builds/1230', headers={ 'Authorization': 'Bearer <your_token>' })
>>> print response.json()

Here's my attempt, it doesn't follow your specs exactly though. Not fully tested, so be cautious.

How to get the last N rows of a pandas DataFrame?

If you are slicing by position, __getitem__ (i.e., slicing with[]) works well, and is the most succinct solution I've found for this problem.

pd.__version__
# '0.24.2'

df = pd.DataFrame({'A': list('aaabbbbc'), 'B': np.arange(1, 9)})
df

   A  B
0  a  1
1  a  2
2  a  3
3  b  4
4  b  5
5  b  6
6  b  7
7  c  8

df[-3:]

   A  B
5  b  6
6  b  7
7  c  8

This is the same as calling df.iloc[-3:], for instance (iloc internally delegates to __getitem__).

As an aside, if you want to find the last N rows for each group, use groupby and GroupBy.tail:

df.groupby('A').tail(2)

   A  B
1  a  2
2  a  3
5  b  6
6  b  7
7  c  8

=SUMPRODUCT( (MONTH($A$2:$A$6)=1) * ($B$2:$B$6) )

Explanation:

• (MONTH($A$2:$A$6)=1) creates an array of 1 and 0, it's 1 when the month is january, thus in your example the returned array would be [1, 1, 1, 0, 0]

• SUMPRODUCT first multiplies each value of the array created in the above step with values of the array ($B$2:$B$6), then it sums them. Hence in your example it does this: (1 * 430) + (1 * 96) + (1 * 440) + (0 * 72.10) + (0 * 72.30)

This works also in OpenOffice and Google Spreadsheets

I had a similar issue on a client site where the client required a authority certificate to be installed automatically for 2000+ windows users.

I created the following .vbs script to import the certificate into the current logged on users firefox cert store.

The script needs to be put in the directory containing a working copy of certutil.exe (the nss version) but programatically determines the firefox profiles location.

Another approach is to first do a searchType: 'count', then and then do a normal search with size set to results.count.

The advantage here is it avoids depending on a magic number for UPPER_BOUND as suggested in this similar SO question, and avoids the extra overhead of building too large of a priority queue that Shay Banon describes here. It also lets you keep your results sorted, unlike scan.

The biggest disadvantage is that it requires two requests. Depending on your circumstance, this may be acceptable.

Below query is appropriate for the last 30 days records

Here, I have used a review table and review_date is a column from the review table

SELECT * FROM reviews WHERE DATE(review_date) >= DATE(NOW()) - INTERVAL 30 DAY
