This is iteration using block approach:

    NSDictionary *dict = @{@"key1":@1, @"key2":@2, @"key3":@3};

    [dict enumerateKeysAndObjectsUsingBlock:^(id key, id obj, BOOL *stop) {
        NSLog(@"%@->%@",key,obj);
        // Set stop to YES when you wanted to break the iteration.
    }];

With autocompletion is very fast to set, and you do not have to worry about writing iteration envelope.

The Response API consumes a (immutable) Blob from which the data can be retrieved in several ways. The OP only asked for ArrayBuffer, and here's a demonstration of it.

var blob = GetABlobSomehow();

// NOTE: you will need to wrap this up in a async block first.
/* Use the await keyword to wait for the Promise to resolve */
await new Response(blob).arrayBuffer();   //=> <ArrayBuffer>

alternatively you could use this:

new Response(blob).arrayBuffer()
.then(/* <function> */);

Note: This API isn't compatible with older (ancient) browsers so take a look to the Browser Compatibility Table to be on the safe side ;)

If the remote branch name begins with special characteres you need to use single quotes around it in the checkout command, or else git won't know which branch you are talking about.

For example, I tried to checkout a remote branch named as #9773 but the command didn't work properly, as shown in the picture below:

For some reason I wondered if the sharp symbol (#) could have something to do with it, and then I tried surrounding the branch name with single quotes, like '#9773' rathen than just #9773, and fortunately it worked fine.

$ git checkout -b '#9773' origin/'#9773'

Use pd.concat to merge a list of DataFrame into a single big DataFrame.

appended_data = []
for infile in glob.glob("*.xlsx"):
    data = pandas.read_excel(infile)
    # store DataFrame in list
    appended_data.append(data)
# see pd.concat documentation for more info
appended_data = pd.concat(appended_data)
# write DataFrame to an excel sheet 
appended_data.to_excel('appended.xlsx')

This is what worked for me.

In the Project panel, right click on the project name, and select Open Module Settings from the popup menu.

then change the Compile SDK Version to the minimum version available (the minimum sdk version you set in the project). wait for android studio to load everything.

It will give you some errors, ignore those.

Now go to your java file and android studio will suggest you import

import android.support.v4.app.FragmentActivity;

Import it, then go back to Open Module Settings and change the compile sdk version back to what it was before.

Wait for things to load and voila.

To run function onLoad

jQuery(window).on("load", function(){
    ..code..
});

To run code onDOMContentLoaded (also called onready)

jQuery(document).ready(function(){
    ..code..
});

or the recommended shorthand for onready

jQuery(function($){
    ..code.. ($ is the jQuery object)
});

onready fires when the document has loaded

onload fires when the document and all the associated content, like the images on the page have loaded.

Since you are working in currency why not simply do this:

Console.Writeline("Earnings this week: {0:c}", answer);

This will format answer as currency, so on my machine (UK) it will come out as:

Earnings this week: £209.00

You're thinking it wrong.

What you are trying to do:

If stdin exists use it, else check whether the user supplied a filename.

What you should be doing instead:

If the user supplies a filename, then use the filename. Else use stdin.

You cannot know the total length of an incoming stream unless you read it all and keep it buffered. You just cannot seek backwards into pipes. This is a limitation of how pipes work. Pipes are not suitable for all tasks and sometimes intermediate files are required.

Although this is the accepted answer, toto_tico's answer below is better :)

Try making the onclick js use 'return' to ensure the desired return value gets used...

<button type="button" value="click me" onclick="return check_me();" />

For ES2016, spread operator for objects. Note: This is after ES6 and so transpiler will need to be adjusted.

const arr = ['a', 'b', 'c'];_x000D_
const obj = {...arr}; // -> {0: "a", 1: "b", 2: "c"} 

Function overloading in Javascript:

Function overloading is the ability of a programming language to create multiple functions of the same name with different implementations. when an overloaded function is called it will run function a specific implementation of that function appropriate to the context of the call. This context is usually the amount of arguments is receives, and it allows one function call to behave differently depending on context.

Javascript doesn't have built-in function overloading. However, this behaviour can be emulated in many ways. Here is a convenient simple one:

function sayHi(a, b) {_x000D_
  console.log('hi there ' + a);_x000D_
  if (b) { console.log('and ' + b) } // if the parameter is present, execute the block_x000D_
}_x000D_
_x000D_
sayHi('Frank', 'Willem');

In scenarios where you don't know how many arguments you will be getting you can use the rest operator which is three dots .... It will convert the remainder of the arguments into an array. Beware of browser compatibilty though. Here is an example:

function foo (a, ...b) {_x000D_
  console.log(b);_x000D_
}_x000D_
_x000D_
foo(1,2,3,4);_x000D_
foo(1,2);

I encountered the same problem... I solved it by creating a custom axios instance. and using that to make a authenticated delete request..

const token = localStorage.getItem('token');
const request = axios.create({
        headers: {
            Authorization: token
        }
    });

await request.delete('<your route>, { data: { <your data> }});

From here:

-Xmn : the size of the heap for the young generation

Young generation represents all the objects which have a short life of time. Young generation objects are in a specific location into the heap, where the garbage collector will pass often. All new objects are created into the young generation region (called "eden"). When an object survive is still "alive" after more than 2-3 gc cleaning, then it will be swap has an "old generation" : they are "survivor".

And a more "official" source from IBM:

-Xmn

Sets the initial and maximum size of the new (nursery) heap to the specified value when using -Xgcpolicy:gencon. Equivalent to setting both -Xmns and -Xmnx. If you set either -Xmns or -Xmnx, you cannot set -Xmn. If you attempt to set -Xmn with either -Xmns or -Xmnx, the VM will not start, returning an error. By default, -Xmn is selected internally according to your system's capability. You can use the -verbose:sizes option to find out the values that the VM is currently using.

Noone here said anything about the one that comes with C++0x. If you are using a compiler and the STL that supports C++0x you could just use that instead of having another lib in your project.

Note that getImageData returns a snapshot. Implications are:

• Changes will not take effect until subsequent putImageData
• getImageData and putImageData calls are relatively slow

nothing new but still want to share my method:

+(NSString*) getDateStringFromSrcFormat:(NSString *) srcFormat destFormat:(NSString *)
destFormat scrString:(NSString *) srcString
{
    NSString *dateString = srcString;
    NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
    //[dateFormatter setDateFormat:@"MM-dd-yyyy"];
    [dateFormatter setDateFormat:srcFormat];
    NSDate *date = [dateFormatter dateFromString:dateString];

    // Convert date object into desired format
    //[dateFormatter setDateFormat:@"yyyy-MM-dd"];
    [dateFormatter setDateFormat:destFormat];
    NSString *newDateString = [dateFormatter stringFromDate:date];
    return newDateString;
}

Batch Normalization is used to normalize the input layer as well as hidden layers by adjusting mean and scaling of the activations. Because of this normalizing effect with additional layer in deep neural networks, the network can use higher learning rate without vanishing or exploding gradients. Furthermore, batch normalization regularizes the network such that it is easier to generalize, and it is thus unnecessary to use dropout to mitigate overfitting.

Right after calculating the linear function using say, the Dense() or Conv2D() in Keras, we use BatchNormalization() which calculates the linear function in a layer and then we add the non-linearity to the layer using Activation().

from keras.layers.normalization import BatchNormalization
model = Sequential()
model.add(Dense(64, input_dim=14, init='uniform'))
model.add(BatchNormalization(epsilon=1e-06, mode=0, momentum=0.9, weights=None))
model.add(Activation('tanh'))
model.add(Dropout(0.5))
model.add(Dense(64, init='uniform'))
model.add(BatchNormalization(epsilon=1e-06, mode=0, momentum=0.9, weights=None))
model.add(Activation('tanh'))
model.add(Dropout(0.5))
model.add(Dense(2, init='uniform'))
model.add(BatchNormalization(epsilon=1e-06, mode=0, momentum=0.9, weights=None))
model.add(Activation('softmax'))

sgd = SGD(lr=0.1, decay=1e-6, momentum=0.9, nesterov=True)
model.compile(loss='binary_crossentropy', optimizer=sgd)
model.fit(X_train, y_train, nb_epoch=20, batch_size=16, show_accuracy=True, 
validation_split=0.2, verbose = 2)

How is Batch Normalization applied?

Suppose we have input a[l-1] to a layer l. Also we have weights W[l] and bias unit b[l] for the layer l. Let a[l] be the activation vector calculated(i.e. after adding the non-linearity) for the layer l and z[l] be the vector before adding non-linearity

1. Using a[l-1] and W[l] we can calculate z[l] for the layer l
2. Usually in feed-forward propagation we will add bias unit to the z[l] at this stage like this z[l]+b[l], but in Batch Normalization this step of addition of b[l] is not required and no b[l] parameter is used.
3. Calculate z[l] means and subtract it from each element
4. Divide (z[l] - mean) using standard deviation. Call it Z_temp[l]

5. Now define new parameters ? and ß that will change the scale of the hidden layer as follows:

   z_norm[l] = ?.Z_temp[l] + ß

In this code excerpt, the Dense() takes the a[l-1], uses W[l] and calculates z[l]. Then the immediate BatchNormalization() will perform the above steps to give z_norm[l]. And then the immediate Activation() will calculate tanh(z_norm[l]) to give a[l] i.e.

a[l] = tanh(z_norm[l])

I had this problem and found that in my proxy generator, which I copied from another service, I forgot to change the name of the service.

I changed this...

Return New Service1DataClient(binding, New EndpointAddress(My.Settings.WCFServiceURL & "/Service1Data.svc"))

to...

Return New Service2DataClient(binding, New EndpointAddress(My.Settings.WCFServiceURL & "/Service2Data.svc"))

It was a simple code error, but nearly impossible to debug. I hope this saves someone time.

I would like to show a little example on how is and == are involved in immutable types. Try that:

a = 19998989890
b = 19998989889 +1
>>> a is b
False
>>> a == b
True

is compares two objects in memory, == compares their values. For example, you can see that small integers are cached by Python:

c = 1
b = 1
>>> b is c
True

You should use == when comparing values and is when comparing identities. (Also, from an English point of view, "equals" is different from "is".)

I know its too late but if you still wanna try

for /d %%X in (*) do (for /d %%a in (%%X) do ( "C:\Program Files\7-Zip\7z.exe" a -tzip "%%X.zip" ".\%%a\" ))

here * is the current folder. for more options try this link

Be careful when you make a class "final". Because if you want to write an unit test for a final class, you cannot subclass this final class in order to use the dependency-breaking technique "Subclass and Override Method" described in Michael C. Feathers' book "Working Effectively with Legacy Code". In this book, Feathers said, "Seriously, it is easy to believe that sealed and final are a wrong-headed mistake, that they should never have been added to programming languages. But the real fault lies with us. When we depend directly on libraries that are out of our control, we are just asking for trouble."

Try this code:

final String[] str = {"one","two","three","asdfgf"};
final RelativeLayout rl = (RelativeLayout) findViewById(R.id.rl);
final TextView[] tv = new TextView[10];

for (int i=0; i<str.length; i++)
{
    tv[i] = new TextView(this); 
    RelativeLayout.LayoutParams params=new RelativeLayout.LayoutParams
         ((int)LayoutParams.WRAP_CONTENT,(int)LayoutParams.WRAP_CONTENT);
    params.leftMargin = 50;
    params.topMargin  = i*50;
    tv[i].setText(str[i]);
    tv[i].setTextSize((float) 20);
    tv[i].setPadding(20, 50, 20, 50);
    tv[i].setLayoutParams(params);
    rl.addView(tv[i]);  
}

The ugly but simpler way: delete your local folder, and clone the remote repository again.

I liked steamer25's solution as it seems the most robust for my purposes. However, when debugging in RStudio (in windows), the path would not get set properly. The reason being that if a breakpoint is set in RStudio, sourcing the file uses an alternate "debug source" command which sets the script path a little differently. Here is the final version which I am currently using which accounts for this alternate behavior within RStudio when debugging:

# @return full path to this script
get_script_path <- function() {
    cmdArgs = commandArgs(trailingOnly = FALSE)
    needle = "--file="
    match = grep(needle, cmdArgs)
    if (length(match) > 0) {
        # Rscript
        return(normalizePath(sub(needle, "", cmdArgs[match])))
    } else {
        ls_vars = ls(sys.frames()[[1]])
        if ("fileName" %in% ls_vars) {
            # Source'd via RStudio
            return(normalizePath(sys.frames()[[1]]$fileName)) 
        } else {
            # Source'd via R console
            return(normalizePath(sys.frames()[[1]]$ofile))
        }
    }
}

You need to specify the format:

DateTime date = DateTime.ParseExact(
    "Tue, 1 Jan 2008 00:00:00 UTC", 
    "ddd, d MMM yyyy HH:mm:ss UTC", 
    CultureInfo.InvariantCulture);

Ascii string to integer conversion is done by the atoi() function.

non-null assertion operator

With the non-null assertion operator we can tell the compiler explicitly that an expression has value other than null or undefined. This is can be useful when the compiler cannot infer the type with certainty but we more information than the compiler.

Example

TS code

function simpleExample(nullableArg: number | undefined | null) {
   const normal: number = nullableArg; 
    //   Compile err: 
    //   Type 'number | null | undefined' is not assignable to type 'number'.
    //   Type 'undefined' is not assignable to type 'number'.(2322)

   const operatorApplied: number = nullableArg!; 
    // compiles fine because we tell compiler that null | undefined are excluded 
}

Compiled JS code

Note that the JS does not know the concept of the Non-null assertion operator since this is a TS feature

"use strict";
function simpleExample(nullableArg) {
    const normal = nullableArg;
    const operatorApplied = nullableArg;
 }

What is the difference between them?

Image: the generic Linux kernel binary image file.

zImage: a compressed version of the Linux kernel image that is self-extracting.

uImage: an image file that has a U-Boot wrapper (installed by the mkimage utility) that includes the OS type and loader information.
A very common practice (e.g. the typical Linux kernel Makefile) is to use a zImage file. Since a zImage file is self-extracting (i.e. needs no external decompressors), the wrapper would indicate that this kernel is "not compressed" even though it actually is.

Note that the author/maintainer of U-Boot considers the (widespread) use of using a zImage inside a uImage questionable:

Actually it's pretty stupid to use a zImage inside an uImage. It is much better to use normal (uncompressed) kernel image, compress it using just gzip, and use this as poayload for mkimage. This way U-Boot does the uncompresiong instead of including yet another uncompressor with each kernel image.

(quoted from https://lists.yoctoproject.org/pipermail/yocto/2013-October/016778.html)

Which type of kernel image do I have to use?

You could choose whatever you want to program for.
For economy of storage, you should probably chose a compressed image over the uncompressed one.
Beware that executing the kernel (presumably the Linux kernel) involves more than just loading the kernel image into memory. Depending on the architecture (e.g. ARM) and the Linux kernel version (e.g. with or without DTB), there are registers and memory buffers that may have to be prepared for the kernel. In one instance there was also hardware initialization that U-Boot performed that had to be replicated.

ADDENDUM

I know that u-boot needs a kernel in uImage format.

That is accurate for all versions of U-Boot which only have the bootm command.
But more recent versions of U-Boot could also have the bootz command that can boot a zImage.

I think actually nvarchar(MAX) can store approximately 1070000000 chars.

You can float your column divs using float: left; and give them widths.

And to make sure none of your other content gets messed up, you can wrap the floated divs within a parent div and give it some clear float styling.

Hope this helps.

Please Note: The following answer only applied to WPF under the 3.5 Framework as NET 4.0 runtime has it's own datetime control.

By default WPF 3.5 does not come with a date time picker like winforms.

However a date picker has been added in the WPF tool kit produced by Microsoft which can be downloaded here. I guess it will become part of the framework in a future release.

It is simple to add a reference to the WPFToolkit.dll, see it in the tool box and distribute with your application by following the instructions on the website.

Before this was available other people had created 3rd party pickers (which you may prefer) or alternatively used the less ideal solution of using the winforms control in a WPF application.

Update: This so question is very similar this one which also has a link to a walk through for the datepicker along with other links.

Just like you do for getting something from the CNode you also need to do for the ANode

XmlNodeList xnList = xml.SelectNodes("/Element[@*]");
foreach (XmlNode xn in xnList)
{
  XmlNode anode = xn.SelectSingleNode("ANode");
    if (anode!= null)
    {
        string id = anode["ID"].InnerText;
        string date = anode["Date"].InnerText;
        XmlNodeList CNodes = xn.SelectNodes("ANode/BNode/CNode");
        foreach (XmlNode node in CNodes)
        {
         XmlNode example = node.SelectSingleNode("Example");
         if (example != null)
         {
            string na = example["Name"].InnerText;
            string no = example["NO"].InnerText;
         }
        }
    }
}

You can use == to compare with a zero value composite literal because all fields are comparable:

if (Session{}) == session  {
    fmt.Println("is zero value")
}

playground example

Because of a parsing ambiguity, parentheses are required around the composite literal in the if condition.

The use of == above applies to structs where all fields are comparable. If the struct contains a non-comparable field (slice, map or function), then the fields must be compared one by one to their zero values.

An alternative to comparing the entire value is to compare a field that must be set to a non-zero value in a valid session. For example, if the player id must be != "" in a valid session, use

if session.playerId == "" {
    fmt.Println("is zero value")
}

if you want to display date along with time when you export to Excel then you can use this

xlWorkSheet.Cells(nRow, 3).NumberFormat = "dd/mm/yy h:mm AM/PM"

I just recompiled curl with configure options pointing to the openssl 1.0.2g library folder and include folder, and I still get this message. When I do ldd on curl, it does not show that it uses either libcrypt.so or libssl.so, so I assume this must mean that even though the make and make install succeeded without errors, nevertheless curl does not have HTTPS support? Configure and make was as follows:

./configure --prefix=/local/scratch/PACKAGES/local --with-ssl=/local/scratch/PACKAGES/local/openssl/openssl-1.0.2g --includedir=/local/scratch/PACKAGES/local/include/openssl/openssl-1.0.2g
make
make test
make install

I should mention that libssl.so.1 is in /local/scratch/PACKAGES/local/lib. It is unclear whether the --with-ssl option should point there or to the directory where the openssl install placed the openssl.cnf file. I chose the latter. But if it were supposed to be the former, the make should have failed with an error that it couldn't find the library.

tboswell 's replace Proof version (which is resilient to repeating pattern in filepath)

Simple ES6

['a','b','',,,'w','b'].filter(v => v);

As people say, JavaScript will convert a string of number to integer, so it is not possible to use directly on an associative array, but objects will work for you in similar way I think.

You can create your object:

var object = {};

And add the values as array works:

object[1] = value;
object[2] = value;

This will give you:

{
  '1': value,
  '2': value
}

After that you can access it like an array in other languages getting the key:

for(key in object)
{
   value = object[key] ;
}

I have tested and works.

If you want to stick with the original List instead of creating a new one, you can something similar to what the Distinct() extension method does internally, i.e. use a HashSet to check for uniqueness:

HashSet<long> set = new HashSet<long>(longs.Count);
longs.RemoveAll(x => !set.Add(x));

The List class provides this convenient RemoveAll(predicate) method that drops all elements not satisfying the condition specified by the predicate. The predicate is a delegate taking a parameter of the list's element type and returning a bool value. The HashSet's Add() method returns true only if the set doesn't contain the item yet. Thus by removing any items from the list that can't be added to the set you effectively remove all duplicates.

I use an alternative to the solution that wrote nifr.

$resultRows = $repository->fetchAll();
uasort($resultRows, function($a, $b){
    if ($a->getProperty() == $b->getProperty()) {
        return 0;
    }
    return ($a->getProperty()< $b->getProperty()) ? -1 : 1;
});

It's quicker than the ORDER BY clause, and without the overhead of the Iterator.

Proxy timeouts are well, for proxies, not for FastCGI...

The directives that affect FastCGI timeouts are client_header_timeout, client_body_timeout and send_timeout.

Edit: Considering what's found on nginx wiki, the send_timeout directive is responsible for setting general timeout of response (which was bit misleading). For FastCGI there's fastcgi_read_timeout which is affecting the fastcgi process response timeout.

HTH.

How about this?

SUM(IF(PaymentType = "credit card", totalamount, 0)) AS CreditCardTotal

You are looking for the greatest common divisor (GCD).

You can calculate it recursively in VBA, like this:

Function GCD(numerator As Integer, denominator As Integer)
  If denominator = 0 Then
    GCD = numerator
  Else
    GCD = GCD(denominator, numerator Mod denominator)
  End If
End Function

And use it in your sheet like this:

   ColumnA   ColumnB   ColumnC
1  33        11        =A1/GCD(A1; B1) & ":" & B1/GCD(A1; B1)
2  25         5        =A2/GCD(A2; B2) & ":" & B2/GCD(A2; B2)

It is recommendable to store the result of the function call in a hidden column and use this result to avoid calling the function twice per row:

   ColumnA   ColumnB   ColumnC        ColumnD
1  33        11        =GCD(A1; B1)   =A1/C1 & ":" & B1/C1
2  25         5        =GCD(A2; B2)   =A2/C2 & ":" & B2/C2

I tend to create a static class containing basic functions for cases like these. They allow me write expressions like

var myValues myItems.Select(x => x.Value).Where(Predicates.IsNotNull);

And the collection of predicate functions:

public static class Predicates
{
    public static bool IsNull<T>(T value) where T : class
    {
        return value == null;
    }

    public static bool IsNotNull<T>(T value) where T : class
    {
        return value != null;
    }

    public static bool IsNull<T>(T? nullableValue) where T : struct
    {
        return !nullableValue.HasValue;
    }

    public static bool IsNotNull<T>(T? nullableValue) where T : struct
    {
        return nullableValue.HasValue;
    }

    public static bool HasValue<T>(T? nullableValue) where T : struct
    {
        return nullableValue.HasValue;
    }

    public static bool HasNoValue<T>(T? nullableValue) where T : struct
    {
        return !nullableValue.HasValue;
    }
}

There is indeed a nice, tidy, CSS-only way to do this (that one may consider "better").

Of all the answers posted here, I only found one that uses calc() successfully (by Dariusz Sikorski). But when posed with: "but it fails if there are only 2 items in the last row" there was no solution expanded.

This solution addresses the OP's question with an alternative to negative margins and addresses the problem posed to Dariusz.

notes:

• This example only demonstrates a 3-column layout
• It uses calc() to let the browser do math the way it wants -- 100%/3 (although 33.3333% should work just as well), and (1em/3)*2 (although .66em should also work well).
• It uses ::after to pad the last row if there are fewer elements than columns

Since nobody has yet mentioned it, the primary linguistic significance of size_t is that the sizeof operator returns a value of that type. Likewise, the primary significance of ptrdiff_t is that subtracting one pointer from another will yield a value of that type. Library functions that accept it do so because it will allow such functions to work with objects whose size exceeds UINT_MAX on systems where such objects could exist, without forcing callers to waste code passing a value larger than "unsigned int" on systems where the larger type would suffice for all possible objects.

If you can do the construction in a single operation, then something like the vstack-with-fancy-indexing answer is a fine approach. But if your condition is more complicated or your rows come in on the fly, you may want to grow the array. In fact the numpythonic way to do something like this - dynamically grow an array - is to dynamically grow a list:

A = np.array([[1,2,3],[4,5,6]])
Alist = [r for r in A]
for i in range(100):
    newrow = np.arange(3)+i
    if i%5:
        Alist.append(newrow)
A = np.array(Alist)
del Alist

Lists are highly optimized for this kind of access pattern; you don't have convenient numpy multidimensional indexing while in list form, but for as long as you're appending it's hard to do better than a list of row arrays.

  //file name must be of the form filename.yourfileExtension
       std::vector<std::string> source;
bool getFileContent(std::string & fileName)
{
    if (fileName.substr(fileName.find_last_of(".") + 1) =="yourfileExtension")
    {

        // Open the File
        std::ifstream in(fileName.c_str());

        // Check if object is valid
        if (!in)
        {
            std::cerr << "Cannot open the File : " << fileName << std::endl;
            return false;
        }
        std::string str;
        // Read the next line from File untill it reaches the end.
        while (std::getline(in, str))
        {
            // Line contains string of length > 0 then save it in vector
            if (str.size() > 0)
                source.push_back(str);
        }
        /*for (size_t i = 0; i < source.size(); i++)
    {
        lexer(source[i], i);
        cout << source[i] << endl;
    }
    */
        //Close The File
        in.close();
        return true;
    }
    else

I know this is a very old thread but I was looking for a solution to the same problem and I came across this before eventually finding the answer and I wanted to just post it here so somebody else in my shoes would have a shorter trek across the internet.

****Note that you probably have to run cmd.exe as an administrator for this to work**

So here we go, open up the prompt (as an adminstrator) and go to your System32 directory. Then run

C:\Windows\System32>cd ras

Now you'll be in the ras directory. Now it's time to create a temporary file with our connection info that we will then append onto the rasphone.pbk file that will allow us to use the rasdial command.

So to create our temp file run:

C:\Windows\System32\ras>copy con temp.txt

Now it will let you type the contents of the file, which should look like this:

[CONNECTION NAME]
MEDIA=rastapi
Port=VPN2-0
Device=WAN Miniport (IKEv2)
DEVICE=vpn
PhoneNumber=vpn.server.address.com

So replace CONNECTION NAME and vpn.server.address.com with the desired connection name and the vpn server address you want.

Make a new line and press Ctrl+Z to finish and save.

Now we will append this onto the rasphone.pbk file that may or may not exist depending on if you already have network connections configured or not. To do this we will run the following command:

C:\Windows\System32\ras>type temp.txt >> rasphone.pbk

This will append the contents of temp.txt to the end of rasphone.pbk, or if rasphone.pbk doesn't exist it will be created. Now we might as well delete our temp file:

C:\Windows\System32\ras>del temp.txt

Now we can connect to our newly configured VPN server with the following command:

C:\Windows\System32\ras>rasdial "CONNECTION NAME" myUsername myPassword

When we want to disconnect we can run:

C:\Windows\System32\ras>rasdial /DISCONNECT

That should cover it! I've included a direct copy and past from the command line of me setting up a connection for and connecting to a canadian vpn server with this method:

Microsoft Windows [Version 6.2.9200]
(c) 2012 Microsoft Corporation. All rights reserved.

C:\Windows\system32>cd ras

C:\Windows\System32\ras>copy con temp.txt

Port=VPN2-0
Device=WAN Miniport (IKEv2)
DEVICE=vpn
PhoneNumber=ca.justfreevpn.com
^Z
        1 file(s) copied.

C:\Windows\System32\ras>type temp.txt >> rasphone.pbk

C:\Windows\System32\ras>del temp.txt

C:\Windows\System32\ras>rasdial "Canada VPN Connection" justfreevpn 2932

Depends

It depends on various things. But in general algorithms using a Divide-and-Conquer / dichotomic approach will perform well for sorting problems as they present interesting average-case complexities.

Basics

To understand which algorithms work best, you will need basic knowledge of algorithms complexity and big-O notation, so you can understand how they rate in terms of average case, best case and worst case scenarios. If required, you'd also have to pay attention to the sorting algorithm's stability.

For instance, usually an efficient algorithm is quicksort. However, if you give quicksort a perfectly inverted list, then it will perform poorly (a simple selection sort will perform better in that case!). Shell-sort would also usually be a good complement to quicksort if you perform a pre-analysis of your list.

Have a look at the following, for "advanced searches" using divide and conquer approaches:

• quicksort
• shellsort
• mergesort

And these more straighforward algorithms for less complex ones:

• bubblesort
• selection sort
• insert sort

Further

The above are the usual suspects when getting started, but there are countless others.

As pointed out by R. in the comments and by kriss in his answer, you may want to have a look at HeapSort, which provides a theoretically better sorting complexity than a quicksort (but will won't often fare better in practical settings). There are also variants and hybrid algorithms (e.g. TimSort).

Dictionary<,> is the equivalent. While it doesn't have a Get(...) method, it does have an indexed property called Item which you can access in C# directly using index notation:

class Test {
  Dictionary<int,String> entities;

  public String getEntity(int code) {
    return this.entities[code];
  }
}

If you want to use a custom key type then you should consider implementing IEquatable<> and overriding Equals(object) and GetHashCode() unless the default (reference or struct) equality is sufficient for determining equality of keys. You should also make your key type immutable to prevent weird things happening if a key is mutated after it has been inserted into a dictionary (e.g. because the mutation caused its hash code to change).

Use ampersand to specify the parent selector.

SCSS syntax:

p {
    margin: 2em auto;

    > a {
        color: red;
    }

    &:before {
        content: "";
    }

    &:after {
        content: "* * *";
    }
}

Try Freshen command:

rpm -Fvh *.rpm

input[type="text"], textarea {

  background-color : #d1d1d1; 

}

Hope that helps :)

Edit: working example, http://jsfiddle.net/C5WxK/

From your example it seems reasonable to assume that the siteIP column is determined by the siteName column (that is, each site has only one siteIP). If this is indeed the case, then there is a simple solution using group by:

select
  sites.siteName,
  sites.siteIP,
  max(history.date)
from sites
inner join history on
  sites.siteName=history.siteName
group by
  sites.siteName,
  sites.siteIP
order by
  sites.siteName;

However, if my assumption is not correct (that is, it is possible for a site to have multiple siteIP), then it is not clear from you question which siteIP you want the query to return in the second column. If just any siteIP, then the following query will do:

select
  sites.siteName,
  min(sites.siteIP),
  max(history.date)
from sites
inner join history on
  sites.siteName=history.siteName
group by
  sites.siteName
order by
  sites.siteName;

You should be aware that in C, unlike Java or C#, there is absolutely no possibility to successfully "guess" the type of object a void* pointer points at. Something similar to getClass() simply doesn't exist, since this information is nowhere to be found. For that reason, the kind of "generic" you are looking for always comes with explicit metainformation, like the int b in your example or the format string in the printf family of functions.

The Best way worked for me, was using Align. I needed to make the profile picture of a user in the bottom center of the Cover picture.

return Container(
  height: 220,
  color: Colors.red,
  child: Stack(
    children: [
      Container(
        height: 160,
        color: Colors.yellow,
      ),
      Align(
        alignment: Alignment.bottomCenter,
        child: UserProfileImage(),
      ),
    ],
  ),
);

This worked like a charm.

NOTE: This answer is for SQL Server 2005. For SQL Server 2008 and later, there are much better methods as seen in the other answers.

You can use INSERT with SELECT UNION ALL:

INSERT INTO MyTable  (FirstCol, SecondCol)
    SELECT  'First' ,1
    UNION ALL
SELECT  'Second' ,2
    UNION ALL
SELECT  'Third' ,3
...

Only for small datasets though, which should be fine for your 4 records.

when you are using 32bits node on 64bits windows(like node-webkit or atom-shell developers), process.platform will echo win32

use

    function isOSWin64() {
      return process.arch === 'x64' || process.env.hasOwnProperty('PROCESSOR_ARCHITEW6432');
    }

To improve on the answer provided by @artofwarfare, here is what I consider a neater way to check for the message attribute and print it or print the Exception object as a fallback.

try:
    pass 
except Exception as e:
    print getattr(e, 'message', repr(e))

The call to repr is optional, but I find it necessary in some use cases.

Update #1:

Following the comment by @MadPhysicist, here's a proof of why the call to repr might be necessary. Try running the following code in your interpreter:

try:
    raise Exception 
except Exception as e:
    print(getattr(e, 'message', repr(e)))
    print(getattr(e, 'message', str(e)))

Update #2:

Here is a demo with specifics for Python 2.7 and 3.5: https://gist.github.com/takwas/3b7a6edddef783f2abddffda1439f533

Having requirements in requirements.txt and egg_dir as a directory

you can build your local cache:

$ pip download -r requirements.txt -d eggs_dir

then, using that "cache" is simple like:

$ pip install -r requirements.txt --find-links=eggs_dir

For completeness, the simplest solution i know with seaborn as of late 2019, if one is using Jupyter:

import seaborn as sns
sns.heatmap(dataframe.corr())

There's a library called Zeta Long Paths that provides a .NET API to work with long paths.

Here's a good article that covers this issue for both .NET and PowerShell: ".NET, PowerShell Path too Long Exception and a .NET PowerShell Robocopy Clone"

Aside from looking into root cause issues like file leaks, etc. in order to do a legitimate increase the "open files" limit and have that persist across reboots, consider editing

/etc/security/limits.conf

by adding something like this

jetty soft nofile 2048
jetty hard nofile 4096

where "jetty" is the username in this case. For more details on limits.conf, see http://linux.die.net/man/5/limits.conf

log off and then log in again and run

ulimit -n

to verify that the change has taken place. New processes by this user should now comply with this change. This link seems to describe how to apply the limit on already running processes but I have not tried it.

The default limit 1024 can be too low for large Java applications.

If you can accept Double Objects than this post is helpful: Initialization of an ArrayList in one line

List<Double> y = Arrays.asList(null, 1.0, 2.0);
Double x = y.get(1);

When updating tables make sure you do not reference the field your updating via the alias.

I just had the error with the following code

update [page] 
set p.pagestatusid = 1
from [page] p
join seed s on s.seedid = p.seedid
where s.providercode = 'agd'
and p.pagestatusid = 0

I had to remove the alias reference in the set statement so it reads like this

update [page] 
set pagestatusid = 1
from [page] p
join seed s on s.seedid = p.seedid
where s.providercode = 'agd'
and p.pagestatusid = 0

There is simpler approach to decode a ByteBuffer into a String without any problems, mentioned by Andy Thomas.

You need to add the LinkedResource into an AlternateView

AlternateView alternateView = AlternateView.CreateAlternateViewFromString("<h3>Client: " + data.client_id + " Has Sent You A Screenshot</h3>" +
                @"<img src=""cid:{0}"" />", null, "text/html");
alternateView.LinkedResources.Add(inline);
mail.AlternateViews.Add(alternateView);

A simple example, where a change on a dropdown list triggers an ajax form-submit to reload a datagrid:

<div id="pnlSearch">

    <% using (Ajax.BeginForm("UserSearch", "Home", new AjaxOptions { UpdateTargetId = "pnlSearchResults" }, new { id="UserSearchForm" }))
    { %>

        UserType: <%: Html.DropDownList("FilterUserType", Model.UserTypes, "--", new { onchange = "$('#UserSearchForm').trigger('submit');" })%>

    <% } %>

</div>

The trigger('onsubmit') is the key thing: it calls the onsubmit function that MVC has grafted onto the form.

NB. The UserSearchResults controller returns a PartialView that renders a table using the supplied Model

<div id="pnlSearchResults">
    <% Html.RenderPartial("UserSearchResults", Model); %>
</div>

First, the code:

from random import choices

def random_name(length=6):
    return "".join(choices("abcdefghijklmnopqrstuvwxyz", k=length))
# ---

from IPython.display import IFrame, display, HTML
import tempfile
from os import unlink

def display_html_to_frame(html, width=600, height=600):
    name = f"temp_{random_name()}.html"
    with open(name, "w") as f:
        print(html, file=f)
    display(IFrame(name, width, height), metadata=dict(isolated=True))
    # unlink(name)
    
def display_html_inline(html):
    display(HTML(html, metadata=dict(isolated=True)))

h="<html><b>Hello</b></html>"    
display_html_to_iframe(h)
display_html_inline(h)

Some quick notes:

• You can generally just use inline HTML for simple items. If you are rendering a framework, like a large JavaScript visualization framework, you may need to use an IFrame. Its hard enough for Jupyter to run in a browser without random HTML embedded.
• The strange parameter, metadata=dict(isolated=True) does not isolate the result in an IFrame, as older documentation suggests. It appears to prevent clear-fix from resetting everything. The flag is no longer documented: I just found using it allowed certain display: grid styles to correctly render.
• This IFrame solution writes to a temporary file. You could use a data uri as described here but it makes debugging your output difficult. The Jupyter IFrame function does not take a data or srcdoc attribute.
• The tempfile module creations are not sharable to another process, hence the random_name().
• If you use the HTML class with an IFrame in it, you get a warning. This may be only once per session.
• You can use HTML('Hello, <b>world</b>') at top level of cell and its return value will render. Within a function, use display(HTML(...)) as is done above. This also allows you to mix display and print calls freely.
• Oddly, IFrames are indented slightly more than inline HTML.

You can use the "Generate script for database objects" feature on SSMS.

1. Right click on the target database
2. Select Tasks > Generate Scripts
3. Choose desired table or specific object
4. Hit the Advanced button
5. Under General, choose value on the Types of data to script. You can select Data only, Schema only, and Schema and data. Schema and data includes both table creation and actual data on the generated script.
6. Click Next until wizard is done

This one solved my challenge.
Hope this will help you as well.

Very neat trick I stumble upon trying some SQL injection, in object explorer in the search box just use your percentage characters, and this will search EVERYTHING stored procedures, functions, views, tables, schema, indexes...I tired of thinking of more :)

Search Pattern

I've checked DamienG's answer in LinqPad. Instead of

g.Group.Max(s => s.uid)

should be

g.Max(s => s.uid)

Thank you!

Also Keep in mind that Hive is a big data warehouse. When you want to drop a table you dont want to lose Gigabytes or Terabytes of data. Generating, moving and copying data at that scale can be time consuming. When you drop a 'Managed' table hive will also trash its data. When you drop a 'External' table only the schema definition from hive meta-store is removed. The data on the hdfs still remains.

You can only have one return value whereas you can have multiple out parameters.

You only need to consider out parameters in those cases.

However, if you need to return more than one parameter from your method, you probably want to look at what you're returning from an OO approach and consider if you're better off return an object or a struct with these parameters. Therefore you're back to a return value again.

I already have used Reportlab in one project.

You can also use it with datetime

$date = new \DateTime();
$nbrDay = $date->format('t');
$lastDay = $date->format('Y-m-t');

You could add the user to the Database Level Role db_datareader.

Members of the db_datareader fixed database role can run a SELECT statement against any table or view in the database.

See Books Online for reference:

http://msdn.microsoft.com/en-us/library/ms189121%28SQL.90%29.aspx

You can add a database user to a database role using the following query:

EXEC sp_addrolemember N'db_datareader', N'userName'

You can include a legend template in the chart options:

//legendTemplate takes a template as a string, you can populate the template with values from your dataset 
var options = {
  legendTemplate : '<ul>'
                  +'<% for (var i=0; i<datasets.length; i++) { %>'
                    +'<li>'
                    +'<span style=\"background-color:<%=datasets[i].lineColor%>\"></span>'
                    +'<% if (datasets[i].label) { %><%= datasets[i].label %><% } %>'
                  +'</li>'
                +'<% } %>'
              +'</ul>'
  }

  //don't forget to pass options in when creating new Chart
  var lineChart = new Chart(element).Line(data, options);

  //then you just need to generate the legend
  var legend = lineChart.generateLegend();

  //and append it to your page somewhere
  $('#chart').append(legend);

You'll also need to add some basic css to get it looking ok.

you can use just

extern allows one module of your program to access a global variable or function declared in another module of your program. You usually have extern variables declared in header files.

If you don't want a program to access your variables or functions, you use static which tells the compiler that this variable or function cannot be used outside of this module.

You are correct in your understanding of the DOM based model. The XML file will be loaded as a whole and all its contents will be built as an in-memory representation of the tree the document represents. This can be time- and memory-consuming, depending on how large the input file is. The benefit of this approach is that you can easily query any part of the document, and freely manipulate all the nodes in the tree.

The DOM approach is typically used for small XML structures (where small depends on how much horsepower and memory your platform has) that may need to be modified and queried in different ways once they have been loaded.

SAX on the other hand is designed to handle XML input of virtually any size. Instead of the XML framework doing the hard work for you in figuring out the structure of the document and preparing potentially lots of objects for all the nodes, attributes etc., SAX completely leaves that to you.

What it basically does is read the input from the top and invoke callback methods you provide when certain "events" occur. An event might be hitting an opening tag, an attribute in the tag, finding text inside an element or coming across an end-tag.

SAX stubbornly reads the input and tells you what it sees in this fashion. It is up to you to maintain all state-information you require. Usually this means you will build up some sort of state-machine.

While this approach to XML processing is a lot more tedious, it can be very powerful, too. Imagine you want to just extract the titles of news articles from a blog feed. If you read this XML using DOM it would load all the article contents, all the images etc. that are contained in the XML into memory, even though you are not even interested in it.

With SAX you can just check if the element name is (e. g.) "title" whenever your "startTag" event method is called. If so, you know that you needs to add whatever the next "elementText" event offers you. When you receive the "endTag" event call, you check again if this is the closing element of the "title". After that, you just ignore all further elements, until either the input ends, or another "startTag" with a name of "title" comes along. And so on...

You could read through megabytes and megabytes of XML this way, just extracting the tiny amount of data you need.

The negative side of this approach is of course, that you need to do a lot more book-keeping yourself, depending on what data you need to extract and how complicated the XML structure is. Furthermore, you naturally cannot modify the structure of the XML tree, because you never have it in hand as a whole.

So in general, SAX is suitable for combing through potentially large amounts of data you receive with a specific "query" in mind, but need not modify, while DOM is more aimed at giving you full flexibility in changing structure and contents, at the expense of higher resource demand.

I faced same error but in a different way.

When you curl a page with a specific SSL protocol.

curl --sslv3 https://example.com

If --sslv3 is not supported by the target server then the error will be

curl: (35) TCP connection reset by peer

You could try something like this using approach for How to find the last field using 'cut':

Explanation

• rev reverses /home/user/mydir/file_name.c to be c.eman_elif/ridym/resu/emoh/
• cut uses dot (ie /) as the delimiter, and chooses the first field, which is c.eman_elif
• lastly, we reverse it again to get file_name.c

$ VAR="/home/user/mydir/file_name.c"
$ echo $VAR | rev | cut -f1 -d"/" | rev
file_name.c

You can try with textContent.

var productId = val[key].textContent;

One more option is to ask MySQL for the query plan. This tells you two things:

• Whether there are any syntax errors in the query, if so the query plan command itself will fail
• How MySQL is planning to execute the query, e.g. what indexes it will use

In MySQL and most SQL databases the query plan command is describe, so you would do:

describe update ...;

C# 6 adds a new feature just for this: extension Add methods. This has always been possible for VB.net but is now available in C#.

Now you don't have to add Add() methods to your classes directly, you can implement them as extension methods. When extending any enumerable type with an Add() method, you'll be able to use it in collection initializer expressions. So you don't have to derive from lists explicitly anymore (as mentioned in another answer), you can simply extend it.

public static class TupleListExtensions
{
    public static void Add<T1, T2>(this IList<Tuple<T1, T2>> list,
            T1 item1, T2 item2)
    {
        list.Add(Tuple.Create(item1, item2));
    }

    public static void Add<T1, T2, T3>(this IList<Tuple<T1, T2, T3>> list,
            T1 item1, T2 item2, T3 item3)
    {
        list.Add(Tuple.Create(item1, item2, item3));
    }

    // and so on...
}

This will allow you to do this on any class that implements IList<>:

var numbers = new List<Tuple<int, string>>
{
    { 1, "one" },
    { 2, "two" },
    { 3, "three" },
    { 4, "four" },
    { 5, "five" },
};
var points = new ObservableCollection<Tuple<double, double, double>>
{
    { 0, 0, 0 },
    { 1, 2, 3 },
    { -4, -2, 42 },
};

Of course you're not restricted to extending collections of tuples, it can be for collections of any specific type you want the special syntax for.

public static class BigIntegerListExtensions
{
    public static void Add(this IList<BigInteger> list,
        params byte[] value)
    {
        list.Add(new BigInteger(value));
    }

    public static void Add(this IList<BigInteger> list,
        string value)
    {
        list.Add(BigInteger.Parse(value));
    }
}

var bigNumbers = new List<BigInteger>
{
    new BigInteger(1), // constructor BigInteger(int)
    2222222222L,       // implicit operator BigInteger(long)
    3333333333UL,      // implicit operator BigInteger(ulong)
    { 4, 4, 4, 4, 4, 4, 4, 4 },               // extension Add(byte[])
    "55555555555555555555555555555555555555", // extension Add(string)
};

C# 7 will be adding in support for tuples built into the language, though they will be of a different type (System.ValueTuple instead). So to it would be good to add overloads for value tuples so you have the option to use them as well. Unfortunately, there are no implicit conversions defined between the two.

public static class ValueTupleListExtensions
{
    public static void Add<T1, T2>(this IList<Tuple<T1, T2>> list,
        ValueTuple<T1, T2> item) => list.Add(item.ToTuple());
}

This way the list initialization will look even nicer.

var points = new List<Tuple<int, int, int>>
{
    (0, 0, 0),
    (1, 2, 3),
    (-1, 12, -73),
};

But instead of going through all this trouble, it might just be better to switch to using ValueTuple exclusively.

var points = new List<(int, int, int)>
{
    (0, 0, 0),
    (1, 2, 3),
    (-1, 12, -73),
};

I have 1 simpler work around...

What you can do is while inserting data/document into your main collection "things" you must insert the attributes in 1 separate collection lets say "things_attributes".

so every time you insert in "things", you do get from "things_attributes" compare values of that document with your new document keys if any new key present append it in that document and again re-insert it.

So things_attributes will have only 1 document of unique keys which you can easily get when ever you require by using findOne()

If the issue is that your SpringBootApplication/Configuration you are bringing in is component scanning the package your test configurations are in, you can actually remove the @Configuration annotation from the test configurations and you can still use them in the @SpringBootTest annotations. For example, if you have a class Application that is your main configuration and a class TestConfiguration that is a configuration for certain, but not all tests, you can set up your classes as follows:

@Import(Application.class) //or the specific configurations you want
//(Optional) Other Annotations that will not trigger an autowire
public class TestConfiguration {
    //your custom test configuration
}

And then you can configure your tests in one of two ways:

1. With the regular configuration:

   @SpringBootTest(classes = {Application.class}) //won't component scan your configuration because it doesn't have an autowire-able annotation
   //Other annotations here
   public class TestThatUsesNormalApplication {
       //my test code
   }
   

2. With the test custom test configuration:

   @SpringBootTest(classes = {TestConfiguration.class}) //this still works!
   //Other annotations here
   public class TestThatUsesCustomTestConfiguration {
       //my test code
   }
   

Combining @Joachim's with the above, you could use

next(iter(my_list[index:index+1]), default)

Examples:

next(iter(range(10)[8:9]), 11)
8
>>> next(iter(range(10)[12:13]), 11)
11

Or, maybe more clear, but without the len

my_list[index] if my_list[index:index + 1] else default

If you are trying to do this, it means you are doing something wrong. Consider using a dict instead.

def show_val(vals, name):
    print "Name:", name, "val:", vals[name]

vals = {'a': 1, 'b': 2}
show_val(vals, 'b')

Output:

Name: b val: 2

1. Select cell B3 and click the Conditional Formatting button in the ribbon and choose "New Rule".
2. Select "Use a formula to determine which cells to format"
3. Enter the formula: =IF(B2="X",IF(B3="Y", TRUE, FALSE),FALSE), and choose to fill green when this is true
4. Create another rule and enter the formula =IF(B2="X",IF(B3="W", TRUE, FALSE),FALSE) and choose to fill red when this is true.

More details - conditional formatting with a formula applies the format when the formula evaluates to TRUE. You can use a compound IF formula to return true or false based on the values of any cells.

$(<img />).attr('src','http://somedomain.com/image.jpg');

Should be better than ajax because if its a gallery and you are looping through a list of pics, if the image is already in cache, it wont send another request to server. It will request in the case of jQuery/ajax and return a HTTP 304 (Not modified) and then use original image from cache if its already there. The above method reduces an empty request to server after the first loop of images in the gallery.

I would like to mention some of the possible ways here together with a pure javascript trick which works across all browsers:

// with jQuery 
$(document).ready(function(){ /* ... */ });

// shorter jQuery version 
$(function(){ /* ... */ });

// without jQuery (doesn't work in older IEs)
document.addEventListener('DOMContentLoaded', function(){ 
    // your code goes here
}, false);

// and here's the trick (works everywhere)
function r(f){/in/.test(document.readyState)?setTimeout('r('+f+')',9):f()}
// use like
r(function(){
    alert('DOM Ready!');
});

The trick here, as explained by the original author, is that we are checking the document.readyState property. If it contains the string in (as in uninitialized and loading, the first two DOM ready states out of 5) we set a timeout and check again. Otherwise, we execute the passed function.

And here's the jsFiddle for the trick which works across all browsers.

Thanks to Tutorialzine for including this in their book.

DON'T USE A TRANSAPENT OR NULL LAYOUT because then the button (or the generic view) will no more highlight at click!!!

I had the same problem and finally I found the correct attribute from Android API to solve the problem. It can apply to any view

Use this in the button specifications

android:background="?android:selectableItemBackground"

This requires API 11

On my linux system to get just the filenames

diff -q /dir1 /dir2|cut -f2 -d' '

You should be able to use a wildcard for your values:

switch -wildcard ($someString.ToLower())
{
    "y*" { "You entered Yes." }
    default { "You entered No." }
}

Regular expressions are also allowed.

switch -regex ($someString.ToLower())
{
    "y(es)?" { "You entered Yes." }
    default { "You entered No." }
}

Try to run Maven from the command line or type "-X" in the text field - you can't break anything this way, at the worst, you'll get an error (I don't have Netbeans; in Eclipse, there is a checkbox "Debug" for this).

When running with debug output enabled, you should see the paths which the exec-maven-plugin plugin uses.

The next step would then be to copy the command into a command prompt or terminal and execute it manually to see if you get a useful error message there.

You can try this:-

string values = "";
foreach(ListItem item in myCBL.Items){
if(item.Selected)
{
values += item.Value.ToString() + ",";  
}
}
values = values.TrimEnd(',');  //To eliminate comma in last.

The easiest way:

from pathlib import Path
from glob import glob

current_dir = Path.cwd()
all_sub_dir_paths = glob(str(current_dir) + '/*/') # returns list of sub directory paths

all_sub_dir_names = [Path(sub_dir).name for sub_dir in all_sub_dir_paths] 

Note the point density in proportional to inverse square of the radius, hence instead of picking r from [0, r_max], pick from [0, r_max^2], then compute your coordinates as:

x = sqrt(r) * cos(angle)
y = sqrt(r) * sin(angle)

This will give you uniform point distribution on a disk.

This can also be done in CSS, for more customisability:

.hoverable {
  position: relative;
}

.hoverable>.hoverable__tooltip {
  display: none;
}

.hoverable:hover>.hoverable__tooltip {
  display: inline;
  position: absolute;
  top: 1em;
  left: 1em;
  background: #888;
  border: 1px solid black;
}

<div class="hoverable">
  <span class="hoverable__main">Main text</span>
  <span class="hoverable__tooltip">Hover text</span>
</div>

(Obviously, styling can be improved)

You need to use an explicit java.util.Iterator to iterate over the Map's entry set rather than being able to use the enhanced For-loop syntax available in Java 6. The following example iterates over a Map of Integer, String pairs, removing any entry whose Integer key is null or equals 0.

Map<Integer, String> map = ...

Iterator<Map.Entry<Integer, String>> it = map.entrySet().iterator();

while (it.hasNext()) {
  Map.Entry<Integer, String> entry = it.next();

  // Remove entry if key is null or equals 0.
  if (entry.getKey() == null || entry.getKey() == 0) {
    it.remove();
  }
}

Maven absolutely was designed for this type of dependency.

mvn package won't install anything in your local repository it just packages the project and leaves it in the target folder.

Do mvn install in parent project (A), with this all the sub-modules will be installed in your computer's Maven repository, if there are no changes you just need to compile/package the sub-module (B) and Maven will take the already packaged and installed dependencies just right.

You just need to a mvn install in the parent project if you updated some portion of the code.

The problem is that you are using SingleOrDefault. This method will only succeed when the collections contains exactly 0 or 1 element. I believe you are looking for FirstOrDefault which will succeed no matter how many elements are in the collection.

Little unrelated but I will still put it here, For other practical purposes shell variables can be used as -

value=10
jq  '."key" = "'"$value"'"' file.json

Imports System.Runtime.InteropServices

This should do what you're looking for:

function clean($string) {
   $string = str_replace(' ', '-', $string); // Replaces all spaces with hyphens.

   return preg_replace('/[^A-Za-z0-9\-]/', '', $string); // Removes special chars.
}

Usage:

echo clean('a|"bc!@£de^&$f g');

Will output: abcdef-g

Edit:

Hey, just a quick question, how can I prevent multiple hyphens from being next to each other? and have them replaced with just 1?

function clean($string) {
   $string = str_replace(' ', '-', $string); // Replaces all spaces with hyphens.
   $string = preg_replace('/[^A-Za-z0-9\-]/', '', $string); // Removes special chars.

   return preg_replace('/-+/', '-', $string); // Replaces multiple hyphens with single one.
}

I had the same problem for a GitHub repository. My account was missing SSH Key. The process is

1. Generate SSH Key
2. Adding a new SSH key to your GitHub account

Then, you can clone the repository with submodules (git clone --recursive YOUR-GIT-REPO-URL)

or

Run git submodule init and git submodule update to fetch submodules in already cloned repository.

try this dirty way

 ('' + obj).includes('{')

You are all wrong! Why? Because all you need is this code to work:

(image View) / C# Img is : your Image box

Keep this as is, without change ("ms-appx:///) this is code not your app name Images is your folder in your project you can change it. dog.png is your file in your folder, as well as i do my folder 'Images' and file 'dog.png' So the uri is :"ms-appx:///Images/dog.png" and my code :

private void Button_Click(object sender, RoutedEventArgs e)
    {
         img.Source = new BitmapImage(new Uri("ms-appx:///Images/dog.png"));
    }

Here is my solution. @Maxim Shoustin's solution has some issue with sorting. I also wrap the whole thing to a directive. The only dependency is UI.Bootstrap.pagination, which did a great job on pagination.

Here is the plunker

Here is the github source code.

If you really want to get the type by name you may use the following:

System.AppDomain.CurrentDomain.GetAssemblies().SelectMany(x => x.GetTypes()).First(x => x.Name == "theassembly");

Note that you can improve the performance of this drastically the more information you have about the type you're trying to load.

Nikita's point is an excellent one: don't confuse mature with bad. XML hasn't changed much.

JDOM would be another alternative to DOM4J.

 app.get('/category', function(req, res) {
  var string = query
  res.redirect('/?valid=' + string);
});

in the ejs you can directly use valid:

<% var k = valid %>

I was getting this error too. I resolved it by installing: https://git-scm.com/

and running the command from the Git Bash window.

This happened to me because I had the 'copyright' symbol in one of my strings! Once it was removed, problem solved.

A good rule of thumb, make sure that characters not appearing on your keyboard are removed if you are seeing this error.

it's valid but like UpTheCreek said 'There are some downsides to each approach'

if you're calling ajax through an tag leave the href="" like this will keep the page reloading and the ajax code will never be called ...

just got this thought would be good to share

It will overflow and wrap around to Long.MIN_VALUE.

Its not too likely though. Even if you increment 1,000,000 times per second it will take about 300,000 years to overflow.

Try layout() which I have used for this in the past by simply creating an empty plot below, properly scaled at around 1/4 or so and placing the legend parts manually in it.

There are some older questions here about legend() which should get you started.

If you want to roll back an individual file from a specific revision and be able to commit, then do:

svn merge -c -[OldRev#] [Filename]

ie. svn merge -c -150 myfile.py

Note the negative on the revision number

There is a new public method get_compiled_select that can print the query before running it. _compile_select is now protected therefore can not be used.

echo $this->db->get_compiled_select(); // before $this->db->get();

You should use a callback parameter:

function Typer(callback)
{
    var srcText = 'EXAMPLE ';
    var i = 0;
    var result = srcText[i];
    var interval = setInterval(function() {
        if(i == srcText.length - 1) {
            clearInterval(interval);
            callback();
            return;
        }
        i++;
        result += srcText[i].replace("\n", "<br />");
        $("#message").html(result);
    },
    100);
    return true;


}

function playBGM () {
    alert("Play BGM function");
    $('#bgm').get(0).play();
}

Typer(function () {
    playBGM();
});

// or one-liner: Typer(playBGM);

So, you pass a function as parameter (callback) that will be called in that if before return.

Also, this is a good article about callbacks.

Update

There has been recent improvements in datetime API with JSR-310.

Instant now = Instant.now();
Instant yesterday = now.minus(1, ChronoUnit.DAYS);
System.out.println(now);
System.out.println(yesterday);

https://ideone.com/91M1eU

Outdated answer

You are subtracting the wrong number:

Use Calendar instead:

private Date yesterday() {
    final Calendar cal = Calendar.getInstance();
    cal.add(Calendar.DATE, -1);
    return cal.getTime();
}

Then, modify your method to the following:

private String getYesterdayDateString() {
        DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
        return dateFormat.format(yesterday());
}

See

• IDEOne Demo

Another way to check an external script is loaded or not, you can use data function of jquery and store a validation flag. Example as :

if(!$("body").data("google-map"))
    {
        console.log("no js");

        $.getScript("https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false&callback=initilize",function(){
            $("body").data("google-map",true);

            },function(){
                alert("error while loading script");
            });
        }
    }
    else
    {
        console.log("js already loaded");
    }

At the beginning of your main method, add this line of code :

final long startTime = System.nanoTime();

And then, at the last line of your main method, you can add :

final long duration = System.nanoTime() - startTime;

duration now contains the time in nanoseconds that your program ran. You can for example print this value like this:

System.out.println(duration);

If you want to show duration time in seconds, you must divide the value by 1'000'000'000. Or if you want a Date object: Date myTime = new Date(duration / 1000); You can then access the various methods of Date to print number of minutes, hours, etc.

You're on a 64-bit system, and don't have 32-bit library support installed.

To install (baseline) support for 32-bit executables

(if you don't use sudo in your setup read note below)

Most desktop Linux systems in the Fedora/Red Hat family:

 pkcon install glibc.i686

Possibly some desktop Debian/Ubuntu systems?:

pkcon install ia32-libs

Fedora or newer Red Hat, CentOS:

 sudo dnf install glibc.i686

Older RHEL, CentOS:

   sudo yum install glibc.i686

Even older RHEL, CentOS:

  sudo yum install glibc.i386

Debian or Ubuntu:

   sudo apt-get install ia32-libs

should grab you the (first, main) library you need.

Once you have that, you'll probably need support libs

Anyone needing to install glibc.i686 or glibc.i386 will probably run into other library dependencies, as well. To identify a package providing an arbitrary library, you can use

 ldd /usr/bin/YOURAPPHERE

if you're not sure it's in /usr/bin you can also fall back on

 ldd $(which YOURAPPNAME)

The output will look like this:

    linux-gate.so.1 =>  (0xf7760000)
    libpthread.so.0 => /lib/libpthread.so.0 (0xf773e000)
    libSM.so.6 => not found

Check for missing libraries (e.g. libSM.so.6 in the above output), and for each one you need to find the package that provides it.

Commands to find the package per distribution family

Fedora/Red Hat Enterprise/CentOS:

 dnf provides /usr/lib/libSM.so.6

or, on older RHEL/CentOS:

 yum provides /usr/lib/libSM.so.6

or, on Debian/Ubuntu:

first, install and download the database for apt-file

 sudo apt-get install apt-file && apt-file update

then search with

 apt-file find libSM.so.6

Note the prefix path /usr/lib in the (usual) case; rarely, some libraries still live under /lib for historical reasons … On typical 64-bit systems, 32-bit libraries live in /usr/lib and 64-bit libraries live in /usr/lib64.

(Debian/Ubuntu organise multi-architecture libraries differently.)

Installing packages for missing libraries

The above should give you a package name, e.g.:

libSM-1.2.0-2.fc15.i686 : X.Org X11 SM runtime library
Repo        : fedora
Matched from:
Filename    : /usr/lib/libSM.so.6

In this example the name of the package is libSM and the name of the 32bit version of the package is libSM.i686.

You can then install the package to grab the requisite library using pkcon in a GUI, or sudo dnf/yum/apt-get as appropriate…. E.g pkcon install libSM.i686. If necessary you can specify the version fully. E.g sudo dnf install ibSM-1.2.0-2.fc15.i686.

Some libraries will have an “epoch” designator before their name; this can be omitted (the curious can read the notes below).

Notes

Warning

Incidentially, the issue you are facing either implies that your RPM (resp. DPkg/DSelect) database is corrupted, or that the application you're trying to run wasn't installed through the package manager. If you're new to Linux, you probably want to avoid using software from sources other than your package manager, whenever possible...

If you don't use "sudo" in your set-up

Type

su -c

every time you see sudo, eg,

su -c dnf install glibc.i686

About the epoch designator in library names

The “epoch” designator before the name is an artifact of the way that the underlying RPM libraries handle version numbers; e.g.

2:libpng-1.2.46-1.fc16.i686 : A library of functions for manipulating PNG image format files
Repo        : fedora
Matched from:
Filename    : /usr/lib/libpng.so.3

Here, the 2: can be omitted; just pkcon install libpng.i686 or sudo dnf install libpng-1.2.46-1.fc16.i686. (It vaguely implies something like: at some point, the version number of the libpng package rolled backwards, and the “epoch” had to be incremented to make sure the newer version would be considered “newer” during updates. Or something similar happened. Twice.)

Updated to clarify and cover the various package manager options more fully (March, 2016)

Considering

$string="We have www/audio path where the audio files are stored";  //Considering the string like this

Either you can use

strstr($string, 'www/audio');

Or

$expStr=explode("www/audio",$string);
$resultString="www/audio".$expStr[1];

With MVC you can simply return a file like this:

public ActionResult ExportData()
{
    System.IO.FileInfo exportFile = //create your ExportFile
    return File(exportFile.FullName, "text/csv", string.Format("Export-{0}.csv", DateTime.Now.ToString("yyyyMMdd-HHmmss")));
}

for /f "usebackq" %A in (`TYPE c:\temp\file.txt ^| find /v /c "" `) do set numlines=%A

in a batch file, use %%A instead of %A

This below code will remove the complete object element from the array, where the phone number is '+1786543589455'

db.collection.update(
  { _id: id },
  { $pull: { 'contact': { number: '+1786543589455' } } }
);

Contacts.add(objt.Data(name, address, contact));

This is not a perfect way to call a constructor. The constructor is called at the time of object creation automatically. If there is no constructor java class creates its own constructor.

The correct way is:

// object creation. 
Data object1 = new Data(name, address, contact);      

// adding Data object to ArrayList object Contacts.
Contacts.add(object1);                              

A far more common answer is that you have some error that is getting appended to whatever your compressing. The solution is to set display_errors = Off in your php.ini file (Check in your terminal if it's On by running php --info and look for "display_errors")

That should do it. And, how do you discover what errors you're actually? Check your PHP error logs whenever you hit that route/page.

Good luclk!

Below is the link which guide in parsing JSON string in android.

http://www.ibm.com/developerworks/xml/library/x-andbene1/?S_TACT=105AGY82&S_CMP=MAVE

Also according to your json string code snippet must be something like this:-

JSONObject mainObject = new JSONObject(yourstring);

JSONObject universityObject = mainObject.getJSONObject("university");
JSONString name = universityObject.getString("name");  
JSONString url = universityObject.getString("url");

Following is the API reference for JSOnObject: https://developer.android.com/reference/org/json/JSONObject.html#getString(java.lang.String)

Same for other object.

As always, http://www.csszengarden.com/. Note that the images aren't public domain.

If all you are looking for is killing a package

pkill package_name 

should work

It can be done all on the client-side using the OnClientClick^[MSDN] event handler and window.open^[MDN]:

<asp:Button 
     runat="server" 
     OnClientClick="window.open('http://www.stackoverflow.com'); return false;">
     Open a new window!
</asp:Button>

As mentioned above, the short answer is no. But I'm in need of something similar in the app I'm working on now, yet the areas where the CSS needs to be different are limited to very specific areas of a page.

If you're like me and don't need to serve up an entirely different stylesheet, another option would be to detect a device running iOS in the way described in this question's selected answer: Detect if device is iOS

Once you've detected the iOS device you could add a class to the area you're targeting using Javascript (eg. the document.getElementsByTagName("yourElementHere")[0].setAttribute("class", "iOS-device");, jQuery, PHP or whatever, and style that class accordingly using the pre-existing stylesheet.

.iOS-device {
      style-you-want-to-set: yada;
}

Yes, but it also means hash(b) == hash(x), so equality of the items isn't enough to make them the same.

What I made, in my case I wanted to show procedure's result in dataGridView:

using (var command = new SqlCommand("ProcedureNameHere", connection) {
            // Set command type and add Parameters
            CommandType = CommandType.StoredProcedure,
            Parameters = { new SqlParameter("@parameterName",parameterValue) }
        }) 
        {
            // Execute command in Adapter and store to dataset
            var adapter = new SqlDataAdapter(command);
            var dataset = new DataSet();
            adapter.Fill(dataset);
            // Display results in DatagridView
            dataGridView1.DataSource = dataset.Tables[0];
        }

If i understand you correctly, (i probably don't)

'SELECT @RowCount = COUNT(*)
                   FROM dbo.Comm_Services
                   WHERE CompanyId = ' + CAST(@CompanyId AS CHAR) + '
                   AND ' + @condition

ngAfterViewInit() of AppComponent is a lifecycle callback Angular calls after the root component and it's children have been rendered and it should fit for your purpose.

The static key word in the main method is used because there isn't any instantiation that take place in the main method. But object is constructed rather than invocation as a result we use the static key word in the main method. In jvm context memory is created when class loads into it.And all static members are present in that memory. if we make the main static now it will be in memory and can be accessible to jvm (class.main(..)) so we can call the main method with out need of even need for heap been created.

I had the same problem building VS 2013 Project with Visual Studio 2017 IDE. The solution was to set the right "Platformtoolset v120 (Visual Studio 2013). Therefor there must be the Windows SDK 8.1 installed. If you want to use Platformtoolset v141 (Visual Studio 2017) there must be Windows SDK 10. The Platformtoolset can be chosen inside the properties dialog of the project: General -> Platformtoolset

I was running into this error while converting from nvarchar to float.
What I had to do was to use the LEFT function on the nvarchar field.

Example: Left(Field,4)

Basically, the query will look like:

Select convert(float,left(Field,4)) from TABLE

Just ridiculous that SQL would complicate it to this extent, while with C# it's a breeze!
Hope it helps someone out there.

You could make use of Typescript's optional chaining. Example:

const name = person?.name;

If the property name exists on the person object you would get its value but if not it would automatically return undefined.

You could make use of this resource for a better understanding.

var theString = "TEST";
char[] myChar = theString.ToCharArray();

I tested this in the C# interactive window of Visual Studio 2019 and got:

char[4] { 'T', 'E', 'S', 'T' }

Update 2020: It's been 7 years since I wrote this answer. It still seems to be getting a lot of attention. In 2013 Newtonsoft Json.Net was THE answer to this problem. Now it's still a good answer to this problem but it's no longer the the only viable option. To add some up-to-date caveats to this answer:

• .Net Core now has the spookily similar System.Text.Json serialiser (see below)
• The days of the JavaScriptSerializer have thankfully passed and this class isn't even in .Net Core. This invalidates a lot of the comparisons ran by Newtonsoft.
• It's also recently come to my attention, via some vulnerability scanning software we use in work that Json.Net hasn't had an update in some time. Updates in 2020 have dried up and the latest version, 12.0.3, is over a year old.
• The speed tests quoted below are comparing an older version of Json.Nt (version 6.0 and like I said the latest is 12.0.3) with an outdated .Net Framework serialiser.

Are Json.Net's days numbered? It's still used a LOT and it's still used by MS librarties. So probably not. But this does feel like the beginning of the end for this library that may well of just run it's course.

Update since .Net Core 3.0

A new kid on the block since writing this is System.Text.Json which has been added to .Net Core 3.0. Microsoft makes several claims to how this is, now, better than Newtonsoft. Including that it is faster than Newtonsoft. as below, I'd advise you to test this yourself .

I would recommend Json.Net, see example below:

List<data> _data = new List<data>();
_data.Add(new data()
{
    Id = 1,
    SSN = 2,
    Message = "A Message"
});

string json = JsonConvert.SerializeObject(_data.ToArray());

//write string to file
System.IO.File.WriteAllText(@"D:\path.txt", json);

Or the slightly more efficient version of the above code (doesn't use a string as a buffer):

//open file stream
using (StreamWriter file = File.CreateText(@"D:\path.txt"))
{
     JsonSerializer serializer = new JsonSerializer();
     //serialize object directly into file stream
     serializer.Serialize(file, _data);
}

Documentation: Serialize JSON to a file

Why? Here's a feature comparison between common serialisers as well as benchmark tests .

Below is a graph of performance taken from the linked article:

This separate post, states that:

Json.NET has always been memory efficient, streaming the reading and writing large documents rather than loading them entirely into memory, but I was able to find a couple of key places where object allocations could be reduced...... (now) Json.Net (6.0) allocates 8 times less memory than JavaScriptSerializer

^{_{Benchmarks appear to be Json.Net 5, the current version (on writing) is 10. What version of standard .Net serialisers used is not mentioned}}

^{_{These tests are obviously from the developers who maintain the library. I have not verified their claims. If in doubt test them yourself.}}

Here is the tutorial to install GBD.

Usually GNU Debugger might not be in your computer, so you would install it first. The installation steps are basic "configure", "make", and "make install".

Once installed, try which gdb in terminal, to find the executable path of GDB.

Its a CORS issue, your api cannot be accessed directly from remote or different origin, In order to allow other ip address or other origins from accessing you api, you should add the 'Access-Control-Allow-Origin' on the api's header, you can set its value to '*' if you want it to be accessible to all, or you can set specific domain or ips like 'http://siteA.com' or 'http://192. ip address ';

Include this on your api's header, it may vary depending on how you are displaying json data,

if your using ajax, to retrieve and display data your header would look like this,

$.ajax({
   url: '',
   headers: {  'Access-Control-Allow-Origin': 'http://The web site allowed to access' },
   data: data,
   type: 'dataType',
   /* etc */
   success: function(jsondata){

   }
})

@mshobnr / @olegkhuss solution made into a simple macro:

{% macro trunc(txt, len) -%}
    {{ txt|length > len ? txt|slice(0, len) ~ '…' : txt }}
{%- endmacro %}

Usage example:

{{ tools.trunc('This is the text to truncate. ', 50) }}

N.b. I import a Twig template containing macros and import it as 'tools' like this (Symfony):

{% import "@AppBundle/tools.html.twig" as tools -%}

Also, I replaced the html character code with the actual character, this should be no problem when using UTF-8 as the file encoding. This way you don't have to use |raw (as it could cause a security issue).

The quick answer is to use the .Split('\\') method.

The print statement in Python converts its arguments to strings, and outputs those strings to stdout. To save the string to a variable instead, only convert it to a string:

a = str(tag.getArtist())

As of Bootstrap 4 - it has a style of:

@media (min-width: 576px)
.modal-dialog {
    max-width: 500px;
}

so if you are looking to resize the modal width to some-width larger, I would suggest using this in your css for example:

.modal-dialog { max-width: 87vw; }

Note that setting width: 87vw; will not override bootstrap's max-width: 500px;.

The thread will block, but the process is still alive.

In a single threaded application, this means everything is blocked while you sleep. In a multithreaded application, only the thread you explicitly 'sleep' will block and the other threads still run within the process.

To complete the answers, here are real-world examples of removing events when you are visiting websites and don't have control over the HTML and JavaScript code generated.

Some annoying websites are preventing you to copy-paste usernames on login forms, which could easily be bypassed if the onpaste event was added with the onpaste="return false" HTML attribute. In this case we just need to right click on the input field, select "Inspect element" in a browser like Firefox and remove the HTML attribute.

However, if the event was added through JavaScript like this:

document.getElementById("lyca_login_mobile_no").onpaste = function(){return false};

We will have to remove the event through JavaScript also:

document.getElementById("lyca_login_mobile_no").onpaste = null;

In my example, I used the ID "lyca_login_mobile_no" since it was the text input ID used by the website I was visiting.

Another way to remove the event (which will also remove all the events) is to remove the node and create a new one, like we have to do if addEventListener was used to add events using an anonymous function that we cannot remove with removeEventListener. This can also be done through the browser console by inspecting an element, copying the HTML code, removing the HTML code and then pasting the HTML code at the same place.

It can also be done faster and automated through JavaScript:

var oldNode = document.getElementById("lyca_login_mobile_no");
var newNode = oldNode.cloneNode(true);
oldNode.parentNode.insertBefore(newNode, oldNode);
oldNode.parentNode.removeChild(oldNode);

Update: if the web app is made using a JavaScript framework like Angular, it looks the previous solutions are not working or breaking the app. Another workaround to allow pasting would be to set the value through JavaScript:

document.getElementById("lyca_login_mobile_no").value = "username";

At the moment, I don't know if there is a way to remove all form validation and restriction events without breaking an app written entirely in JavaScript like Angular.

There is a tmux plugin for this.

Check out tmux-resurrect

Restore tmux environment after system restart.

Tmux is great, except when you have to restart the computer. You lose all the running programs, working directories, pane layouts etc. There are helpful management tools out there, but they require initial configuration and continuous updates as your workflow evolves or you start new projects.

tmux-resurrect saves all the little details from your tmux environment so it can be completely restored after a system restart (or when you feel like it). No configuration is required. You should feel like you never quit tmux.

Or tmux-continuum

Features:

• continuous saving of tmux environment
• automatic tmux start when computer/server is turned on
• automatic restore when tmux is started

I realize this is quite late, but I needed something like this so I whipped up a quick and dirty method to do this.

+ (UIImage *) image:(UIImage *)image withAlpha:(CGFloat)alpha{

    // Create a pixel buffer in an easy to use format
    CGImageRef imageRef = [image CGImage];
    NSUInteger width = CGImageGetWidth(imageRef);
    NSUInteger height = CGImageGetHeight(imageRef);
    CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB();

    UInt8 * m_PixelBuf = malloc(sizeof(UInt8) * height * width * 4);

    NSUInteger bytesPerPixel = 4;
    NSUInteger bytesPerRow = bytesPerPixel * width;
    NSUInteger bitsPerComponent = 8;
    CGContextRef context = CGBitmapContextCreate(m_PixelBuf, width, height,
                                                 bitsPerComponent, bytesPerRow, colorSpace,
                                                 kCGImageAlphaPremultipliedLast | kCGBitmapByteOrder32Big);

    CGContextDrawImage(context, CGRectMake(0, 0, width, height), imageRef);
    CGContextRelease(context);

    //alter the alpha
    int length = height * width * 4;
    for (int i=0; i<length; i+=4)
    {
        m_PixelBuf[i+3] =  255*alpha;
    }


    //create a new image
    CGContextRef ctx = CGBitmapContextCreate(m_PixelBuf, width, height,
                                                 bitsPerComponent, bytesPerRow, colorSpace,
                                                 kCGImageAlphaPremultipliedLast | kCGBitmapByteOrder32Big);

    CGImageRef newImgRef = CGBitmapContextCreateImage(ctx);  
    CGColorSpaceRelease(colorSpace);
    CGContextRelease(ctx);  
    free(m_PixelBuf);

    UIImage *finalImage = [UIImage imageWithCGImage:newImgRef];
    CGImageRelease(newImgRef);  

    return finalImage;
}

You can first cast object to string and then cast the string to int; for example:

string str_myobject = myobject.ToString();
int int_myobject = int.Parse(str_myobject);

this worked for me.

Take a vector of integer and a key (that we find in vector )....Now we are traversing the vector until found the key value or last index(otherwise).....If we found key then print the position , otherwise print "-1".

     #include <bits/stdc++.h>  
     using namespace std;  

     int main()  
      {  
          vector<int>str;  
          int flag,temp key, ,len,num;

           flag=0;
           cin>>len;

           for(int i=1; i<=len; i++)  
           {
               cin>>key;
               v.push_back(key);
           }

           cin>>num;

           for(int i=1; i<=len; i++)  
           {  
             if(str[i]==num)  
             {  
                flag++;  
                temp=i-1;
                break;
             }  
           }

         if(flag!=0)    cout<<temp<<endl;
         else           cout<<"-1"<<endl;   
         str.clear();   

         return 0;  
      }

This is what I did for Installing Anaconda Python 3.6 version and Tensorflow on Window 10 64bit.And It was success!

1. Download Anaconda Python 3.6 version for Window 64bit.

2. Create a conda environment named tensorflow by invoking the following command:

   C:> conda create -n tensorflow 
   

3. Activate the conda environment by issuing the following command:

   C:> activate tensorflow
   (tensorflow)C:>  # Your prompt should change 
   

4. Download “tensorflow-1.0.1-cp36-cp36m-win_amd64.whl” from here. (For my case, the file will be located in “C:\Users\Joshua\Downloads” once after downloaded).

5. Install the Tensorflow by using following command:

   (tensorflow)C:>pip install C:\Users\Joshua\Downloads\ tensorflow-1.0.1-cp36-cp36m-win_amd64.whl
   

This is what I got after the installing:

6. Validate installation by entering following command in your Python environment:

   import tensorflow as tf
   hello = tf.constant('Hello, TensorFlow!')
   sess = tf.Session()
   print(sess.run(hello))
   

If the output you got is 'Hello, TensorFlow!',that means you have successfully install your Tensorflow.

Use the array_search function.

Example from php.net

$array = array(0 => 'blue', 1 => 'red', 2 => 'green', 3 => 'red');

$key = array_search('green', $array); // $key = 2;
$key = array_search('red', $array);   // $key = 1;

select#xyz {
  border:0px;
  outline:0px;
}

Exact solution.

This could be the possible solution

var str = 'RACK NO:Stock;PRODUCT TYPE:Stock Sale;PART N0:0035719061;INDEX NO:21A627 042;PART NAME:SPRING;';  
var newstr = str.split(':')[1].split(';')[0]; // return value as 'Stock'

console.log('stringvalue',newstr)

Something like this?

<div onclick="alert('test');">

</div>

If you wanna change the name, that will be displayed on your screen, right under your icon, in Xcode 4, go to Targets->info->Bundle Display Name and change it to whatever you want.

We should always go for equals() method for comparison for two integers.Its the recommended practice.

If we compare two integers using == that would work for certain range of integer values (Integer from -128 to 127) due to JVM's internal optimisation.

Please see examples:

Case 1:

Integer a = 100; Integer b = 100;

if (a == b) {
    System.out.println("a and b are equal");
} else {
   System.out.println("a and b are not equal");
}

In above case JVM uses value of a and b from cached pool and return the same object instance(therefore memory address) of integer object and we get both are equal.Its an optimisation JVM does for certain range values.

Case 2: In this case, a and b are not equal because it does not come with the range from -128 to 127.

Integer a = 220; Integer b = 220;

if (a == b) {
    System.out.println("a and b are equal");
} else {
   System.out.println("a and b are not equal");
}

Proper way:

Integer a = 200;             
Integer b = 200;  
System.out.println("a == b? " + a.equals(b)); // true

I hope this helps.

I'm a bit late to the party but autocomplpop might be helpful.

Instead of Activity use context.It works for me.

@Override
    public void onAttach(Context context) {
        super.onAttach(context);
        try {
            mListener = (OnFragmentInteractionListener) context;
        } catch (ClassCastException e) {
            throw new ClassCastException(context.toString()
                    + " must implement OnFragmentInteractionListener");
        }
}

Double underscore. That mangles the name. The variable can still be accessed, but it's generally a bad idea to do so.

Use single underscores for semi-private (tells python developers "only change this if you absolutely must") and doubles for fully private.

The best way around this would be to create an Excel called 'launcher.xlsm' in the same folder as the file you wish to open. In the 'launcher' file put the following code in the 'Workbook' object, but set the constant TargetWBName to be the name of the file you wish to open.

Private Const TargetWBName As String = "myworkbook.xlsx"

'// First, a function to tell us if the workbook is already open...
Function WorkbookOpen(WorkBookName As String) As Boolean
' returns TRUE if the workbook is open
    WorkbookOpen = False
    On Error GoTo WorkBookNotOpen
    If Len(Application.Workbooks(WorkBookName).Name) > 0 Then
        WorkbookOpen = True
        Exit Function
    End If
WorkBookNotOpen:
End Function

Private Sub Workbook_Open()
    'Check if our target workbook is open
    If WorkbookOpen(TargetWBName) = False Then
        'set calculation to manual
        Application.Calculation = xlCalculationManual
        Workbooks.Open ThisWorkbook.Path & "\" & TargetWBName
        DoEvents
        Me.Close False
    End If
End Sub

Set the constant 'TargetWBName' to be the name of the workbook that you wish to open. This code will simply switch calculation to manual, then open the file. The launcher file will then automatically close itself. *NOTE: If you do not wish to be prompted to 'Enable Content' every time you open this file (depending on your security settings) you should temporarily remove the 'me.close' to prevent it from closing itself, save the file and set it to be trusted, and then re-enable the 'me.close' call before saving again. Alternatively, you could just set the False to True after Me.Close

You can use paste with print

print(paste0("Current working dir: ", wd))

or cat

cat("Current working dir: ", wd)

Yes, the DataTable.Select method supports boolean operators in the same way that you would use them in a "real" SQL statement:

DataRow[] results = table.Select("A = 'foo' AND B = 'bar' AND C = 'baz'");

See DataColumn.Expression in MSDN for the syntax supported by DataTable's Select method.

@Alexander 's solution is the one which I was looking for. But it was causing an error - TypeError: a.stopPropagation is not a function.

So I made the event with KeyboardEvent. Here's the working code and Javascript version is very convenient for React.js projects. I also used this for my React.js project.

(function selectFirst(input) {
  let _addEventListener = input.addEventListener
    ? input.addEventListener
    : input.attachEvent;

  function addEventListenerWrapper(type, listener) {
    if (type === 'keydown') {
      console.log('keydown');

      let orig_listener = listener;
      listener = event => {
        let suggestion_selected =
          document.getElementsByClassName('pac-item-selected').length > 0;

        if (event.keyCode === 13 && !suggestion_selected) {
          let simulated_downarrow = new KeyboardEvent('keydown', {
            bubbles: true,
            cancelable: true,
            keyCode: 40
          });

          orig_listener.apply(input, [simulated_downarrow]);
        }

        orig_listener.apply(input, [event]);
      };
    }

    _addEventListener.apply(input, [type, listener]);

Hope this can help someone, :)

I think oracle is smart enough to convert the less efficient one (whichever that is) into the other. So I think the answer should rather depend on the readability of each (where I think that IN clearly wins)

Setting a -vendor prefix that isn't supported in older browsers can cause them to throw an exception with .css. Instead detect the supported prefix first:

// Start with a fall back
var newCss = { 'zoom' : ui.value };

// Replace with transform, if supported
if('WebkitTransform' in document.body.style) 
{
    newCss = { '-webkit-transform': 'scale(' + ui.value + ')'};
}
// repeat for supported browsers
else if('transform' in document.body.style) 
{
    newCss = { 'transform': 'scale(' + ui.value + ')'};
}

// Set the CSS
$('.user-text').css(newCss)

That works in old browsers. I've done scale here but you could replace it with whatever other transform you wanted.

Because the picker script is using moment.js to parse the format string, you can read the docs there for proper format strings.

But for 24Hr time, use HH instead of hh in the format.

$(function () {
    $('#startTime, #endTime').datetimepicker({
        format: 'HH:mm',
        pickDate: false,
        pickSeconds: false,
        pick12HourFormat: false            
    });
});

Hashtables/Dictionaries are O(1) performance, meaning that performance is not a function of size. That's important to know.

EDIT: In practice, the average time complexity for Hashtable/Dictionary<> lookups is O(1).

I had the same problem, but in my case it turned out to be a cookie issue. The guys working on the back-end had changed the path of the JSESSIONID cookie that's set when we log in to our app, and I had an old cookie by that name on my computer, but with the old path. So when I tried logging in the browser (Chrome) sent two cookies called JSESSIONID, with different values, to the server - which understandably confused it - so it cancelled the request. Deleting the cookies from my computer fixed it.

I have used in this way. Its Working fine!

$rules = [

            'password' => [

                    'required',

                    'string',

                    'min:6',

                'max:12',             // must be at least 8 characters in length

                ],

            'confirm_password' => 'required|same:password|min:6'

        ];

I had this issue and the problem was that Navicat was connected to my local Postgres db. Once I disconnected Navicat the problem disappeared.

EDIT:

Also, as an absolute last resort you can back up your data then run this command:

sudo kill -15 `ps -u postgres -o pid`

... which will kill everything that the postgres user is accessing. Avoid doing this on a production machine but you shouldn't have a problem with a development environment. It is vital that you ensure every postgres process has really terminated before attempting to restart PostgreSQL after this.

EDIT 2:

Due to this unix.SE post I've changed from kill -9 to kill -15.

In Windows with Git Bash you can use the following to add a repository

ssh-agent bash -c 'ssh-add "key-address"; git remote add origin "rep-address"'

for example:

ssh-agent bash -c 'ssh-add /d/test/PrivateKey.ppk; git remote add origin [email protected]:test/test.git'

Which private key is in drive D, folder test of computer. Also if you want to clone a repository, you can change git remote add origin with git clone.

After enter this to Git Bash, it will ask you for passphrase!

Be Aware that openssh private key and putty private key are different!

If you have created your keys with puttygen, you must convert your private key to openssh!

This will help to find the spaces in the beginning, middle and ending:

var regexp = /\s/g

The syntax for providing a single value can be confusing for inexperienced Python users.

Given the query

INSERT INTO mytable (fruit) VALUES (%s)

The value passed to cursor.execute must still be a tuple even though it is a singleton, so we must provide a single element tuple, like this: (value,).

cursor.execute("""INSERT INTO mytable (fruit) VALUES (%s)""", ('apple',))

Require the JSON library, and use to_json.

require 'json'
tempHash = {
    "key_a" => "val_a",
    "key_b" => "val_b"
}
File.open("public/temp.json","w") do |f|
  f.write(tempHash.to_json)
end

Your temp.json file now looks like:

{"key_a":"val_a","key_b":"val_b"}

This should be faster than iterating and will work regardless of shape.

numpy.isnan(myarray).any()

Edit: 30x faster:

import timeit
s = 'import numpy;a = numpy.arange(10000.).reshape((100,100));a[10,10]=numpy.nan'
ms = [
    'numpy.isnan(a).any()',
    'any(numpy.isnan(x) for x in a.flatten())']
for m in ms:
    print "  %.2f s" % timeit.Timer(m, s).timeit(1000), m

Results:

  0.11 s numpy.isnan(a).any()
  3.75 s any(numpy.isnan(x) for x in a.flatten())

Bonus: it works fine for non-array NumPy types:

>>> a = numpy.float64(42.)
>>> numpy.isnan(a).any()
False
>>> a = numpy.float64(numpy.nan)
>>> numpy.isnan(a).any()
True

>>> df.groupby('id').first()
     value
id        
1    first
2    first
3    first
4   second
5    first
6    first
7   fourth

If you need id as column:

>>> df.groupby('id').first().reset_index()
   id   value
0   1   first
1   2   first
2   3   first
3   4  second
4   5   first
5   6   first
6   7  fourth

To get n first records, you can use head():

>>> df.groupby('id').head(2).reset_index(drop=True)
    id   value
0    1   first
1    1  second
2    2   first
3    2  second
4    3   first
5    3   third
6    4  second
7    4   fifth
8    5   first
9    6   first
10   6  second
11   7  fourth
12   7   fifth

You can also create custom alert dialog by creating an xml file.

dialoglayout.xml

   <EditText
    android:id="@+id/dialog_txt_name"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_margin="10dp"
    android:hint="Name"
    android:singleLine="true" >

    <requestFocus />
  </EditText>
   <Button
        android:id="@+id/btn_login"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="60dp"
        android:background="@drawable/red"
        android:padding="5dp"
        android:textColor="#ffffff"
        android:text="Submit" />

    <Button
        android:id="@+id/btn_cancel"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="10dp"
        android:layout_toRightOf="@+id/btn_login"
        android:background="@drawable/grey"
        android:padding="5dp"
        android:text="Cancel" />

The Java Code:

@Override//to popup alert dialog
public void onClick(View arg0) {
    // TODO Auto-generated method stub
    showDialog(DIALOG_LOGIN);
});


@Override
protected Dialog onCreateDialog(int id) {
    AlertDialog dialogDetails = null;

    switch (id) {
        case DIALOG_LOGIN:
            LayoutInflater inflater = LayoutInflater.from(this);
            View dialogview = inflater.inflate(R.layout.dialoglayout, null);
            AlertDialog.Builder dialogbuilder = new AlertDialog.Builder(this);
            dialogbuilder.setTitle("Title");
            dialogbuilder.setView(dialogview);
            dialogDetails = dialogbuilder.create();
            break;
    }
    return dialogDetails;
}

@Override
protected void onPrepareDialog(int id, Dialog dialog) {
    switch (id) {
        case DIALOG_LOGIN:
             final AlertDialog alertDialog = (AlertDialog) dialog;
             Button loginbutton = (Button) alertDialog
                .findViewById(R.id.btn_login);
             Button cancelbutton = (Button) alertDialog
                .findViewById(R.id.btn_cancel);
             userName = (EditText) alertDialog
                .findViewById(R.id.dialog_txt_name);
             loginbutton.setOnClickListener(new View.OnClickListener() {
                  @Override
                  public void onClick(View v) {
                      String name = userName.getText().toString();
                      Toast.makeText(Activity.this, name,Toast.LENGTH_SHORT).show();
             });
             cancelbutton.setOnClickListener(new View.OnClickListener() {
                      @Override
                      public void onClick(View v) {
                           alertDialog.dismiss();
                      }
             });
             break;
   }
}
