I had a similir problem, but in my case, I put a row in the leading of the ListView, and it was consuming all the space, of course. I just had to take the Row out of the leading, and it was solved. I would recommend to check if the problem is a larger widget than its container can have.

Expanded(child:MyListView())

you can use

moviesTitles.map((title) => Tab(text: title)).toList()

example:

    bottom: new TabBar(
      controller: _controller,
      isScrollable: true,
      tabs:
        moviesTitles.map((title) => Tab(text: title)).toList()
      ,
    ),

I just wanted to use the import and export in JavaScript files.

Everyone says it's not possible. But, as of May 2018, it's possible to use above in plain Node.js, without any modules like Babel, etc.

Here is a simple way to do it.

Create the below files, run, and see the output for yourself.

Also don't forget to see Explanation below.

File myfile.mjs

function myFunc() {
    console.log("Hello from myFunc")
}

export default myFunc;

File index.mjs

import myFunc from "./myfile.mjs"  // Simply using "./myfile" may not work in all resolvers

myFunc();

Run

node  --experimental-modules  index.mjs

Output

(node:12020) ExperimentalWarning: The ESM module loader is experimental.

Hello from myFunc

Explanation:

1. Since it is experimental modules, .js files are named .mjs files
2. While running you will add --experimental-modules to the node index.mjs
3. While running with experimental modules in the output you will see: "(node:12020) ExperimentalWarning: The ESM module loader is experimental. "
4. I have the current release of Node.js, so if I run node --version, it gives me "v10.3.0", though the LTE/stable/recommended version is 8.11.2 LTS.
5. Someday in the future, you could use .js instead of .mjs, as the features become stable instead of Experimental.
6. More on experimental features, see: https://nodejs.org/api/esm.html

1. Use the 'jet' colormap for a transition between blue and red.
2. Use pcolor() with the vmin, vmax parameters.

It is detailed in this answer: https://stackoverflow.com/a/3376734/21974

You could alter the figsize by passing a tuple showing the width, height parameters you would like to keep.

import matplotlib.pyplot as plt

fig, ax = plt.subplots(figsize=(10,10))         # Sample figsize in inches
sns.heatmap(df1.iloc[:, 1:6:], annot=True, linewidths=.5, ax=ax)

EDIT

I remember answering a similar question of yours where you had to set the index as TIMESTAMP. So, you could then do something like below:

df = df.set_index('TIMESTAMP')
df.resample('30min').mean()
fig, ax = plt.subplots()
ax = sns.heatmap(df.iloc[:, 1:6:], annot=True, linewidths=.5)
ax.set_yticklabels([i.strftime("%Y-%m-%d %H:%M:%S") for i in df.index], rotation=0)

For the head of the dataframe you posted, the plot would look like:

For a 2d numpy array, simply use imshow() may help you:

import matplotlib.pyplot as plt
import numpy as np


def heatmap2d(arr: np.ndarray):
    plt.imshow(arr, cmap='viridis')
    plt.colorbar()
    plt.show()


test_array = np.arange(100 * 100).reshape(100, 100)
heatmap2d(test_array)

This code produces a continuous heatmap.

You can choose another built-in colormap from here.

You can select the columns of a groupby:

In [11]: df.groupby(['Country', 'Item_Code'])[["Y1961", "Y1962", "Y1963"]].sum()
Out[11]:
                       Y1961  Y1962  Y1963
Country     Item_Code
Afghanistan 15            10     20     30
            25            10     20     30
Angola      15            30     40     50
            25            30     40     50

Note that the list passed must be a subset of the columns otherwise you'll see a KeyError.

I made this:

function repeat(func, times) {
    for (var i=0; i<times; i++) {
        func(i);
    }
}

Usage:

repeat(function(i) {
    console.log("Hello, World! - "+i);
}, 5)

/*
Returns:
Hello, World! - 0
Hello, World! - 1
Hello, World! - 2
Hello, World! - 3
Hello, World! - 4
*/

The i variable returns the amount of times it has looped - useful if you need to preload an x amount of images.

Microsoft started to address the issue in late 2015 by releasing VisualStudioUninstaller.

They abandoned the solution for a while; however work has begun again as of April 2016.

There has finally been an official release for this uninstaller in April 2016 which is described as being "designed to cleanup/scorch all Preview/RC/RTM releases of Visual Studio 2013, Visual Studio 2015 and Visual Studio vNext".

You should call this function from the controller.

angular.module('App', [])
  .controller('CinemaCtrl', ['$scope', function($scope) {
    myFunction();
  }]);

Even with normal javascript/html your function won't run on page load as all your are doing is defining the function, you never call it. This is really nothing to do with angular, but since you're using angular the above would be the "angular way" to invoke the function.

Obviously better still declare the function in the controller too.

Edit: Actually I see your "onload" - that won't get called as angular injects the HTML into the DOM. The html is never "loaded" (or the page is only loaded once).

I don't know what the .tex extension on your file means. If we are saying that it is any file with any extension you have several methods of reading it.

I have to assume you are using windows because you have mentioned notepad++.

1. Use notepad++. Right click on the file and choose "edit with notepad++"

2. Use notepad Change the filename extension to .txt and double click the file.

3. Use command prompt. Open the folder that your file is in. Hold down shift and right click. (not on the file, but in the folder that the file is in.) Choose "open command window here" from the command prompt type: "type filename.tex"

If these don't work, I would need more detail as to how they are not working. Errors that you may be getting or what you may expect to be in the file might help.

For the latest version of the API the exact opposite seems to be true for me.

When calling the url https://maps.googleapis.com/maps/api/geocode/json?address=<address>&key=<key> I was getting the following error

You must use an API key to authenticate each request to Google Maps Platform APIs. For additional information, please refer to http://g.co/dev/maps-no-account

Once I switched the order to https://maps.googleapis.com/maps/api/geocode/json?key=<key>&address=<address> it worked fine.

Note that the error message received above was the message I got when going directly to the URL in the browser. When I called the API from a software program I received an HTML response with basically the following message:

We're sorry... but your computer or network may be sending automated queries. To protect our users, we can't process your request right now.

My best guess as to the answer: Consider these 3 options for how to get the CSRF token down from the server to the browser.

1. In the request body (not an HTTP header).
2. In a custom HTTP header, not Set-Cookie.
3. As a cookie, in a Set-Cookie header.

I think the 1st one, request body (while demonstrated by the Express tutorial I linked in the question), is not as portable to a wide variety of situations; not everyone is generating every HTTP response dynamically; where you end up needing to put the token in the generated response might vary widely (in a hidden form input; in a fragment of JS code or a variable accessible by other JS code; maybe even in a URL though that seems generally a bad place to put CSRF tokens). So while workable with some customization, #1 is a hard place to do a one-size-fits-all approach.

The second one, custom header, is attractive but doesn't actually work, because while JS can get the headers for an XHR it invoked, it can't get the headers for the page it loaded from.

That leaves the third one, a cookie carried by a Set-Cookie header, as an approach that is easy to use in all situations (anyone's server will be able to set per-request cookie headers, and it doesn't matter what kind of data is in the request body). So despite its downsides, it was the easiest method for frameworks to implement widely.

It provides nothing else but a standardization of the data. The values it creates are known under several different names, one of them being z-scores ("Z" because the normal distribution is also known as the "Z distribution").

More can be found here:

http://en.wikipedia.org/wiki/Standard_score

I have found this way of reading strings from files to work best for me

String st, full;
full="";
BufferedReader br = new BufferedReader(new FileReader(URL));
while ((st=br.readLine())!=null) {
    full+=st;
}

"full" will be the completed combination of all of the lines. If you want to add a line break between the lines of text you would do full+=st+"\n";

Bash

To get list of keys in Bash, follow the these steps.

First, define the following wrapper function to make it simple to use (copy and paste into shell):

function memcmd() {
  exec {memcache}<>/dev/tcp/localhost/11211
  printf "%s\n%s\n" "$*" quit >&${memcache}
  cat <&${memcache}
}

Memcached 1.4.31 and above

You can use lru_crawler metadump all command to dump (most of) the metadata for (all of) the items in the cache.

As opposed to cachedump, it does not cause severe performance problems and has no limits on the amount of keys that can be dumped.

Example command by using the previously defined function:

memcmd lru_crawler metadump all

See: ReleaseNotes1431.

Memcached 1.4.30 and below

Get list of slabs by using items statistics command, e.g.:

memcmd stats items

For each slub class, you can get list of items by specifying slub id along with limit number (0 - unlimited):

memcmd stats cachedump 1 0
memcmd stats cachedump 2 0
memcmd stats cachedump 3 0
memcmd stats cachedump 4 0
...

^{Note: You need to do this for each memcached server.}

To list all the keys from all stubs, here is the one-liner (per one server):

for id in $(memcmd stats items | grep -o ":[0-9]\+:" | tr -d : | sort -nu); do
    memcmd stats cachedump $id 0
done

^{Note: The above command could cause severe performance problems while accessing the items, so it's not advised to run on live.}

Notes:

stats cachedump only dumps the HOT_LRU (IIRC?), which is managed by a background thread as activity happens. This means under a new enough version which the 2Q algo enabled, you'll get snapshot views of what's in just one of the LRU's.

If you want to view everything, lru_crawler metadump 1 (or lru_crawler metadump all) is the new mostly-officially-supported method that will asynchronously dump as many keys as you want. you'll get them out of order but it hits all LRU's, and unless you're deleting/replacing items multiple runs should yield the same results.

You could try to create your own color palette using the RColorBrewer package

my_palette <- colorRampPalette(c("green", "black", "red"))(n = 1000)

and see how this looks like. But I assume in your case only scaling would help if you really want to keep the black in "the middle". You can simply use my_palette instead of the redgreen()

I recommend that you check out the RColorBrewer package, they have pretty nice in-built palettes, and see interactive website for colorbrewer.

No.

localStorage is accessible by any webpage, and if you have the key, you can change whatever data you want.

That being said, if you can devise a way to safely encrypt the keys, it doesn't matter how you transfer the data, if you can contain the data within a closure, then the data is (somewhat) safe.

You must use the fa class:

<i class="fa">
   &#xf000;
</i>

<i class="fa fa-2x">
   &#xf000;
</i>

import matplotlib.pyplot as plt
import numpy as np
from matplotlib.colors import ListedColormap

#discrete color scheme
cMap = ListedColormap(['white', 'green', 'blue','red'])

#data
np.random.seed(42)
data = np.random.rand(4, 4)
fig, ax = plt.subplots()
heatmap = ax.pcolor(data, cmap=cMap)

#legend
cbar = plt.colorbar(heatmap)

cbar.ax.get_yaxis().set_ticks([])
for j, lab in enumerate(['$0$','$1$','$2$','$>3$']):
    cbar.ax.text(.5, (2 * j + 1) / 8.0, lab, ha='center', va='center')
cbar.ax.get_yaxis().labelpad = 15
cbar.ax.set_ylabel('# of contacts', rotation=270)


# put the major ticks at the middle of each cell
ax.set_xticks(np.arange(data.shape[1]) + 0.5, minor=False)
ax.set_yticks(np.arange(data.shape[0]) + 0.5, minor=False)
ax.invert_yaxis()

#labels
column_labels = list('ABCD')
row_labels = list('WXYZ')
ax.set_xticklabels(column_labels, minor=False)
ax.set_yticklabels(row_labels, minor=False)

plt.show()

You were very close. Once you have a reference to the color bar axis, you can do what ever you want to it, including putting text labels in the middle. You might want to play with the formatting to make it more visible.

Here is some better usage of java for scanner

try(Scanner sc = new Scanner(System.in)) {

    //Use sc as you need

} catch (Exception e) {

        //  handle exception

}

You want set_ticks_position rather than set_label_position:

ax.xaxis.set_ticks_position('top') # the rest is the same

The accepted answer offers a solution which requires changing of the underlying data frame. This is not necessary. One can also simply factorise within the aes() call directly or create a vector for that instead.

This is certainly not much different than user Drew Steen's answer, but with the important difference of not changing the original data frame.

level_order <- c('virginica', 'versicolor', 'setosa') #this vector might be useful for other plots/analyses

ggplot(iris, aes(x = factor(Species, level = level_order), y = Petal.Width)) + geom_col()

or

level_order <- factor(iris$Species, level = c('virginica', 'versicolor', 'setosa'))

ggplot(iris, aes(x = level_order, y = Petal.Width)) + geom_col()

or
directly in the aes() call without a pre-created vector:

ggplot(iris, aes(x = factor(Species, level = c('virginica', 'versicolor', 'setosa')), y = Petal.Width)) + geom_col()

If you want an interactive heatmap from a Pandas DataFrame and you are running a Jupyter notebook, you can try the interactive Widget Clustergrammer-Widget, see interactive notebook on NBViewer here, documentation here

And for larger datasets you can try the in-development Clustergrammer2 WebGL widget (example notebook here)

You are comparing a jQuery object (jQuery('input:first')) to strings (the elements of the array).
Change the code in order to compare the input's value (wich is a string) to the array elements:

if (jQuery.inArray(jQuery("input:first").val(), ar) != -1)

The inArray method returns -1 if the element wasn't found in the array, so as your bonus answer to how to determine if an element is not in an array, use this :

if(jQuery.inArray(el,arr) == -1){
    // the element is not in the array
};

Another Simple way is to create & invoke the function validate() when the form loads & when submit button is clicked. By using checked property we check whether the checkbox is selected or not. cbox[0] has an index 0 which is used to access the first value (i.e Male) with name="gender"

You can do the following:

function validate() {_x000D_
  var cbox = document.forms["myForm"]["gender"];_x000D_
  if (_x000D_
    cbox[0].checked == false &&_x000D_
    cbox[1].checked == false &&_x000D_
    cbox[2].checked == false_x000D_
  ) {_x000D_
    alert("Please Select Gender");_x000D_
    return false;_x000D_
  } else {_x000D_
    alert("Successfully Submited");_x000D_
    return true;_x000D_
  }_x000D_
}

<form onload="return validate()" name="myForm">_x000D_
  <input type="checkbox" name="gender" value="male"> Male_x000D_
_x000D_
  <input type="checkbox" name="gender" value="female"> Female_x000D_
_x000D_
  <input type="checkbox" name="gender" value="other"> Other <br>_x000D_
_x000D_
  <input type="submit" name="submit" value="Submit" onclick="validate()">_x000D_
</form>

Please take a look at Zdenek Kalal's Predator tracker. It requires some training, but it can actively learn how the tracked object looks at different orientations and scales and does it in realtime!

The source code is available on his site. It's in MATLAB, but perhaps there is a Java implementation already done by a community member. I have succesfully re-implemented the tracker part of TLD in C#. If I remember correctly, TLD is using Ferns as the keypoint detector. I use either SURF or SIFT instead (already suggested by @stacker) to reacquire the object if it was lost by the tracker. The tracker's feedback makes it easy to build with time a dynamic list of sift/surf templates that with time enable reacquiring the object with very high precision.

If you're interested in my C# implementation of the tracker, feel free to ask.

In phpMyAdmin v.4.6.5.2 there's a checkbox option "The first line of the file contains the table column names...." :

There is a css3 solution here if that is acceptable. It supports the graceful degradation approach where css3 isn't supported. you just won't have any transparency.

to get the hex equivalent of 80% (CC) take (pct / 100) * 255 and convert to hex.

Use the addslashes function:

 // Outputs: Is your name O\'Reilly?
   echo addslashes($str);

As mentioned by nicholas.hauschild injecting Spring context is not a good idea. In your case, @Scope("request") is enough to fix it. But let say you need several instances of LoginAction in controller method. In this case, I would recommend to create the bean of Supplier (Spring 4 solution):

    @Bean
    public Supplier<LoginAction> loginActionSupplier(LoginAction loginAction){
        return () -> loginAction;
    }

Then inject it into controller:

@Controller
public class HomeController {
    @Autowired
    private  Supplier<LoginAction> loginActionSupplier;  

Here is a great cheat sheet for vim:

1) Use it to ensure an ordered execution of callbacks:

var step1 = new Deferred();
var step2 = new Deferred().done(function() { return step1 });
var step3 = new Deferred().done(function() { return step2 });

step1.done(function() { alert("Step 1") });
step2.done(function() { alert("Step 2") });
step3.done(function() { alert("All done") });
//now the 3 alerts will also be fired in order of 1,2,3
//no matter which Deferred gets resolved first.

step2.resolve();
step3.resolve();
step1.resolve();

2) Use it to verify the status of the app:

var loggedIn = logUserInNow(); //deferred
var databaseReady = openDatabaseNow(); //deferred

jQuery.when(loggedIn, databaseReady).then(function() {
  //do something
});

Im my browser, this doesn't work at all. The tooltip field doesn't show a link, but <a href='#' onClick='alert('Hello World!')>The Link</a>. I'm using FF 3.6.12.

You'll have to do this by hand with JS and CSS. Begin here

DailyJS has a good tutorial (long series of 24 posts) that walks you through all the aspects of building a notepad app (including all the possible extras).

Heres an overview of the tutorial: http://dailyjs.com/2010/11/01/node-tutorial/

And heres a link to all the posts: http://dailyjs.com/tags.html#nodepad

Hopefully people will find this answer as there are many, many posts about this on the web. Many people suggested it was an .htaccess problem, and for me it was. However, I had been looking in the .htaccess in the root, not in the .htaccess in the wp-admin folder. Normally, I work on this site in particular through terminal services, so when it booted me and I couldn't log back in, I was trying to access it from my home computer (and it's IP).

Silly me forgot the IP restriction I had placed in the wp-admin .htaccess file.

AuthName "Protected"
AuthType Basic
<Limit GET POST>
order deny,allow
deny from all
allow from 11.11.11.11
</Limit> 

If you have something like this in your wp-admin .htaccess files, that would easily explain why all the sites you work on ceased to function at the same time. Internet providers occasionally rotate IPs so that nobody is running a server from home without paying for it.

JavaScript will get the job done.

Get all links in the document and compare their reference URLs to the document's URL. If there is a match, add a class to that link.

JavaScript

<script>
    currentLinks = document.querySelectorAll('a[href="'+document.URL+'"]')
    currentLinks.forE??ach(function(link) {
        link.className += ' current-link')
    });

Other Notes

Taraman's jQuery answer above only searches on [href] which will return link tags and tags other than a which rely on the href attribute. Searching on a[href='*https://urlofcurrentpage.com*'] captures only those links which meets the criteria and therefore runs faster.

In addtion, if you don't need to rely on the jQuery library, a vanilla JavaScript solution is definitely the way to go.

Edit: For a better approximation of Alejandro's answer, see below.

I know this is an old question, but wanted to add something to Alejandro's anwser: If you want a nice smoothed image without using py-sphviewer you can instead use np.histogram2d and apply a gaussian filter (from scipy.ndimage.filters) to the heatmap:

import numpy as np
import matplotlib.pyplot as plt
import matplotlib.cm as cm
from scipy.ndimage.filters import gaussian_filter


def myplot(x, y, s, bins=1000):
    heatmap, xedges, yedges = np.histogram2d(x, y, bins=bins)
    heatmap = gaussian_filter(heatmap, sigma=s)

    extent = [xedges[0], xedges[-1], yedges[0], yedges[-1]]
    return heatmap.T, extent


fig, axs = plt.subplots(2, 2)

# Generate some test data
x = np.random.randn(1000)
y = np.random.randn(1000)

sigmas = [0, 16, 32, 64]

for ax, s in zip(axs.flatten(), sigmas):
    if s == 0:
        ax.plot(x, y, 'k.', markersize=5)
        ax.set_title("Scatter plot")
    else:
        img, extent = myplot(x, y, s)
        ax.imshow(img, extent=extent, origin='lower', cmap=cm.jet)
        ax.set_title("Smoothing with  $\sigma$ = %d" % s)

plt.show()

Produces:

The scatter plot and s=16 plotted on top of eachother for Agape Gal'lo (click for better view):

One difference I noticed with my gaussian filter approach and Alejandro's approach was that his method shows local structures much better than mine. Therefore I implemented a simple nearest neighbour method at pixel level. This method calculates for each pixel the inverse sum of the distances of the n closest points in the data. This method is at a high resolution pretty computationally expensive and I think there's a quicker way, so let me know if you have any improvements.

Update: As I suspected, there's a much faster method using Scipy's scipy.cKDTree. See Gabriel's answer for the implementation.

Anyway, here's my code:

import numpy as np
import matplotlib.pyplot as plt
import matplotlib.cm as cm


def data_coord2view_coord(p, vlen, pmin, pmax):
    dp = pmax - pmin
    dv = (p - pmin) / dp * vlen
    return dv


def nearest_neighbours(xs, ys, reso, n_neighbours):
    im = np.zeros([reso, reso])
    extent = [np.min(xs), np.max(xs), np.min(ys), np.max(ys)]

    xv = data_coord2view_coord(xs, reso, extent[0], extent[1])
    yv = data_coord2view_coord(ys, reso, extent[2], extent[3])
    for x in range(reso):
        for y in range(reso):
            xp = (xv - x)
            yp = (yv - y)

            d = np.sqrt(xp**2 + yp**2)

            im[y][x] = 1 / np.sum(d[np.argpartition(d.ravel(), n_neighbours)[:n_neighbours]])

    return im, extent


n = 1000
xs = np.random.randn(n)
ys = np.random.randn(n)
resolution = 250

fig, axes = plt.subplots(2, 2)

for ax, neighbours in zip(axes.flatten(), [0, 16, 32, 64]):
    if neighbours == 0:
        ax.plot(xs, ys, 'k.', markersize=2)
        ax.set_aspect('equal')
        ax.set_title("Scatter Plot")
    else:
        im, extent = nearest_neighbours(xs, ys, resolution, neighbours)
        ax.imshow(im, origin='lower', extent=extent, cmap=cm.jet)
        ax.set_title("Smoothing over %d neighbours" % neighbours)
        ax.set_xlim(extent[0], extent[1])
        ax.set_ylim(extent[2], extent[3])
plt.show()

Result:

asort() - Maintains key association: yes.

sort() - Maintains key association: no.

In addition to the great reply about grokking vi, it should be noted that vim does add some very vi-like features that make using vi commands nicer. The one that comes to mind first are text objects: instead of {!}fmt to reformat the current paragraph, !apfmt does the same. It works by first specifying that we want to select a text object, which is the current paragraph. Similar, to change the current string literal (foo to bar for an example), instead of T"ct"bar (move to just after the previous ", change until just before the next ", insert bar), you can say ci"bar: change inside (innermost) quotes, inserting bar.

Thinking in terms of text objects instead of movement commands is quite nice.

If you use all of the months in your code, your IDE won't let you compile, so I think you don't need unit testing.

But if you are using them with reflection, even if you delete one month, it will compile, so it's valid to put a unit test.

I solved this in c. It takes around 48 ms to run on my machine (with around 98% of the time spent loading the dictionary from disk and creating the trie). The dictionary is /usr/share/dict/american-english which has 62886 words.

The ability to create UML diagrams similar to pretzels with mad cow disease is not actually a useful software development skill.

The whole point of diagramming code is to visualise connections, to see the shape of a design. But once you pass a certain rather low level of complexity, the visualisation is too much to process mentally. Making connections pictorially is only simple if you stick to straight lines, which typically makes the diagram much harder to read than if the connections were cleverly grouped and routed along the cardinal directions.

Use diagrams only for broad communication purposes, and only when they're understood to be lies.

Here is the briefest summary I could make of the two strongest arguments for and against using the new operator:

Argument against new

1. Functions designed to be instantiated as objects using the new operator can have disastrous effects if they are incorrectly invoked as normal functions. A function's code in such a case will be executed in the scope where the function is called, instead of in the scope of a local object as intended. This can cause global variables and properties to get overwritten with disastrous consequences.
2. Finally, writing function Func(), and then calling Func.prototype and adding stuff to it so that you can call new Func() to construct your object seems ugly to some programmers, who would rather use another style of object inheritance for architectural and stylistic reasons.

For more on this argument check out Douglas Crockford's great and concise book Javascript: The Good Parts. In fact check it out anyway.

Argument in favor of new

1. Using the new operator along with prototypal assignment is fast.
2. That stuff about accidentally running a constructor function's code in the global namespace can easily be prevented if you always include a bit of code in your constructor functions to check to see if they are being called correctly, and, in the cases where they aren't, handling the call appropriately as desired.

See John Resig's post for a simple explanation of this technique, and for a generally deeper explanation of the inheritance model he advocates.

Note that except in the simplest of cases, the Enum.HasFlag carries a heavy performance penalty in comparison to writing out the code manually. Consider the following code:

[Flags]
public enum TestFlags
{
    One = 1,
    Two = 2,
    Three = 4,
    Four = 8,
    Five = 16,
    Six = 32,
    Seven = 64,
    Eight = 128,
    Nine = 256,
    Ten = 512
}


class Program
{
    static void Main(string[] args)
    {
        TestFlags f = TestFlags.Five; /* or any other enum */
        bool result = false;

        Stopwatch s = Stopwatch.StartNew();
        for (int i = 0; i < 10000000; i++)
        {
            result |= f.HasFlag(TestFlags.Three);
        }
        s.Stop();
        Console.WriteLine(s.ElapsedMilliseconds); // *4793 ms*

        s.Restart();
        for (int i = 0; i < 10000000; i++)
        {
            result |= (f & TestFlags.Three) != 0;
        }
        s.Stop();
        Console.WriteLine(s.ElapsedMilliseconds); // *27 ms*        

        Console.ReadLine();
    }
}

Over 10 million iterations, the HasFlags extension method takes a whopping 4793 ms, compared to the 27 ms for the standard bitwise implementation.

I have subscribed to quite a few podcasts but the ones I try and listen to weekly are:

One way can be to circularly store the values in the buffer array. and calculate average this way.

int j = (int) (counter % size);
buffer[j] = mostrecentvalue;
avg = (avg * size - buffer[j - 1 == -1 ? size - 1 : j - 1] + buffer[j]) / size;

counter++;

// buffer[j - 1 == -1 ? size - 1 : j - 1] is the oldest value stored

The whole thing runs in a loop where most recent value is dynamic.

Angular @NgModule constructs:

1. import { x } from 'y';: This is standard typescript syntax (ES2015/ES6 module syntax) for importing code from other files. This is not Angular specific. Also this is technically not part of the module, it is just necessary to get the needed code within scope of this file.
2. imports: [FormsModule]: You import other modules in here. For example we import FormsModule in the example below. Now we can use the functionality which the FormsModule has to offer throughout this module.
3. declarations: [OnlineHeaderComponent, ReCaptcha2Directive]: You put your components, directives, and pipes here. Once declared here you now can use them throughout the whole module. For example we can now use the OnlineHeaderComponent in the AppComponent view (html file). Angular knows where to find this OnlineHeaderComponent because it is declared in the @NgModule.
4. providers: [RegisterService]: Here our services of this specific module are defined. You can use the services in your components by injecting with dependency injection.

Example module:

// Angular
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms';

// Components
import { AppComponent } from './app.component';
import { OfflineHeaderComponent } from './offline/offline-header/offline-header.component';
import { OnlineHeaderComponent } from './online/online-header/online-header.component';

// Services
import { RegisterService } from './services/register.service';

// Directives
import { ReCaptcha2Directive } from './directives/re-captcha2.directive';

@NgModule({
  declarations: [
    OfflineHeaderComponent,,
    OnlineHeaderComponent,
    ReCaptcha2Directive,
    AppComponent
  ],
  imports: [
    BrowserModule,
    FormsModule,
  ],
  providers: [
    RegisterService,
  ],
  entryComponents: [
    ChangePasswordComponent,
    TestamentComponent,
    FriendsListComponent,
    TravelConfirmComponent
  ],
  bootstrap: [AppComponent]
})
export class AppModule { }

You can use code like this

The filter is empty string. The filename is AnyName but not blank

        openFileDialog.FileName = "AnyFile";
        openFileDialog.Filter = string.Empty;
        openFileDialog.CheckFileExists = false;
        openFileDialog.CheckPathExists = false;

You've created a new repository and added some files to the index, but you haven't created your first commit yet. After you've done:

 git add a_text_file.txt 

... do:

 git commit -m "Initial commit."

... and those errors should go away.

re install your java. First check your OS version.

I don't know this off the top of my head, but look in the file which shows the user's name, etc in the header of the page after the user has logged in. It might help if you turned on template hints (see this tutorial.

When you find the line such as "Hello <? //code for showing username?>", just copy that line and show it where you need to

this procedure has done very good for me in the last couple of years. to run it just type sp_radhe

Regarding putting sp_radhe in the master database

I use the following code and make it a system stored procedure

exec sys.sp_MS_marksystemobject 'sp_radhe'

Regarding the transaction isolation level

Questions About T-SQL Transaction Isolation Levels You Were Too Shy to Ask

Jonathan Kehayias

Once you change the transaction isolation level it only changes when the scope exits at the end of the procedure or a return call, or if you change it explicitly again using SET TRANSACTION ISOLATION LEVEL.

In addition the TRANSACTION ISOLATION LEVEL is only scoped to the stored procedure, so you can have multiple nested stored procedures that execute at their own specific isolation levels.

Another Ionic way. Using this ion-buttons tag, and the right keyword puts all the buttons in this group to the right. I made some custom toggle buttons that i wanted on one line, but the group to be right justified.

I know that this post is old and you figured this out a long time ago, but just to save the people who will read this some time.

You probably forgot to add annotation to the entity you are passing to the endpoint, so Jersey does not know how to process the POJO it receives. Annotate the pojo with something like this:

@XmlRootElement(name = "someName")

For Chrome on Android, you can use the -webkit-tap-highlight-color CSS property:

-webkit-tap-highlight-color is a non-standard CSS property that sets the color of the highlight that appears over a link while it's being tapped. The highlighting indicates to the user that their tap is being successfully recognized, and indicates which element they're tapping on.

To remove the highlighting completely, you can set the value to transparent:

-webkit-tap-highlight-color: transparent;

Be aware that this might have consequences on accessibility: see outlinenone.com

Chr(10) is the Line Feed character and Chr(13) is the Carriage Return character.

You probably won't notice a difference if you use only one or the other, but you might find yourself in a situation where the output doesn't show properly with only one or the other. So it's safer to include both.

Historically, Line Feed would move down a line but not return to column 1:

This  
    is  
        a  
            test.

Similarly Carriage Return would return to column 1 but not move down a line:

This  
is  
a  
test.

Paste this into a text editor and then choose to "show all characters", and you'll see both characters present at the end of each line. Better safe than sorry.

Try this:

SHOW TABLES FROM nameOfDatabase;

My home-grown regular expression replace function can be used for this.

Demo

See this DB-Fiddle demo, which returns the second word ("I") from a famous sonnet and the number of occurrences of it (1).

SQL

Assuming MySQL 8 or later is being used (to allow use of a Common Table Expression), the following will return the second word and the number of occurrences of it:

WITH cte AS (
     SELECT digits.idx,
            SUBSTRING_INDEX(SUBSTRING_INDEX(words, '~', digits.idx + 1), '~', -1) word
     FROM
     (SELECT reg_replace(UPPER(txt),
                         '[^''’a-zA-Z-]+',
                         '~',
                         TRUE,
                         1,
                         0) AS words
      FROM tbl) delimited
     INNER JOIN
     (SELECT @row := @row + 1 as idx FROM 
      (SELECT 0 UNION ALL SELECT 1 UNION ALL SELECT 3 UNION ALL SELECT 4 UNION ALL SELECT 5 UNION ALL SELECT 6 UNION ALL SELECT 6 UNION ALL SELECT 7 UNION ALL SELECT 8 UNION ALL SELECT 9) t1,
      (SELECT 0 UNION ALL SELECT 1 UNION ALL SELECT 3 UNION ALL SELECT 4 UNION ALL SELECT 5 UNION ALL SELECT 6 UNION ALL SELECT 6 UNION ALL SELECT 7 UNION ALL SELECT 8 UNION ALL SELECT 9) t2, 
      (SELECT 0 UNION ALL SELECT 1 UNION ALL SELECT 3 UNION ALL SELECT 4 UNION ALL SELECT 5 UNION ALL SELECT 6 UNION ALL SELECT 6 UNION ALL SELECT 7 UNION ALL SELECT 8 UNION ALL SELECT 9) t3, 
      (SELECT 0 UNION ALL SELECT 1 UNION ALL SELECT 3 UNION ALL SELECT 4 UNION ALL SELECT 5 UNION ALL SELECT 6 UNION ALL SELECT 6 UNION ALL SELECT 7 UNION ALL SELECT 8 UNION ALL SELECT 9) t4, 
      (SELECT @row := -1) t5) digits
     ON LENGTH(REPLACE(words, '~' , '')) <= LENGTH(words) - digits.idx)
SELECT c.word,
       subq.occurrences
FROM cte c
LEFT JOIN (
  SELECT word,
         COUNT(*) AS occurrences
  FROM cte
  GROUP BY word
) subq
ON c.word = subq.word
WHERE idx = 1; /* idx is zero-based so 1 here gets the second word */

Explanation

A few tricks are used in the SQL above and some accreditation is needed. Firstly the regular expression replacer is used to replace all continuous blocks of non-word characters - each being replaced by a single tilda (~) character. Note: A different character could be chosen instead if there is any possibility of a tilda appearing in the text.

The technique from this answer is then used for transforming a string with delimited values into separate row values. It's combined with the clever technique from this answer for generating a table consisting of a sequence of incrementing numbers: 0 - 10,000 in this case.

It looks like github has a simple UI for creating branches. I opened the branch drop-down and it prompts me to "Find or create a branch ...". Type the name of your new branch, then click the "create" button that appears.

To retrieve your new branch from github, use the standard git fetch command.

I'm not sure this will help your underlying problem, though, since the underlying data being pushed to the server (the commit objects) is the same no matter what branch it's being pushed to.

I needed to convert a timeval struct (seconds, microseconds) containing UNIX time to DateTime without losing precision and haven't found an answer here so I thought I just might add mine:

DateTime _epochTime = new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc);
private DateTime UnixTimeToDateTime(Timeval unixTime)
{
    return _epochTime.AddTicks(
        unixTime.Seconds * TimeSpan.TicksPerSecond +
        unixTime.Microseconds * TimeSpan.TicksPerMillisecond/1000);
}

I know this question is old, but it deserves an answer. I personally prefer to create a WSDL by hand and test for compliance using SoapUI. But sometimes (specially for complex WSDLs), you have three ways to generate one out of an XSD:

1. Generating a WSDL from a schema using Eclipse (probably the most user-friendly)
2. Generating a WSDL via CXF (my favorite)
3. Generating a WSDL via conventions using Spring WS (my least favorite)

I prefer the CXF approach since I'm a CLI guy. If it has a CLI, you can automate (that's my motto). And I like the Spring WS approach the least since it uses a lot of framework specific conventions.

There are more people who know CXF (I believe) than Spring WS. So anything that can throw a learning curve for a new engineer (without any clear advantage or ROI) is something I frown upon.

It should also go w/o saying that any generated WSDL should be tested for validity and compliance (and tweaked till it complies), and that your application publishes a static wsdl (as opposed to returning an auto-generated one.)

It's been my experience that you start with a WS-I compliant wsdl and then your application auto-generates (and returns to consumers) a non-compliant one.

In other words, beware of auto magic.

The links are wrong, you have to do this:

<ul class="nav navbar-nav item">
    <li>
        <a [routerLink]="['/home']" routerLinkActive="active">Home</a>
    </li>
    <li>
        <a [routerLink]="['/about']" routerLinkActive="active">About this
        </a>
    </li>
</ul>

stack size can indeed be unlimited. _STK_LIM is the default, _STK_LIM_MAX is something that differs per architecture, as can be seen from include/asm-generic/resource.h:

/*
 * RLIMIT_STACK default maximum - some architectures override it:
 */
#ifndef _STK_LIM_MAX
# define _STK_LIM_MAX           RLIM_INFINITY
#endif

As can be seen from this example generic value is infinite, where RLIM_INFINITY is, again, in generic case defined as:

/*
 * SuS says limits have to be unsigned.
 * Which makes a ton more sense anyway.
 *
 * Some architectures override this (for compatibility reasons):
 */
#ifndef RLIM_INFINITY
# define RLIM_INFINITY          (~0UL)
#endif

So I guess the real answer is - stack size CAN be limited by some architecture, then unlimited stack trace will mean whatever _STK_LIM_MAX is defined to, and in case it's infinity - it is infinite. For details on what it means to set it to infinite and what implications it might have, refer to the other answer, it's way better than mine.

My problem was that I hadn't built the project yet (oops). Don't know if this really helps anyone, but just make sure you build everything before clicking links.

You can use a spinner and set the spinnerMode to dialog, and set the layout_width and layout_height to 0, so that the main view does not show, only the dialog (dropdown view). Call performClick in the button click listener.

    mButtonAdd.setOnClickListener(view -> {
        spinnerAddToList.performClick();
    });

Layout:

    <Spinner
        android:id="@+id/spinnerAddToList"
        android:layout_width="0dp"
        android:layout_height="0dp"
        android:layout_marginTop="10dp"
        android:prompt="@string/select_from_list"
        android:theme="@style/ThemeOverlay.AppCompat.Light"
        android:spinnerMode="dialog"/>

The advantage of this is you can customize your spinner any way you want.

See my answer here to customize spinner: Overriding dropdown list style for Spinner in Dialog mode

According to Microsoft

(DLL) Dynamic link libraries are files that contain data, code, or resources needed for the running of applications. These are files that are created by the windows ecosystem and can be shared between two or more applications.

When a program or software runs on Windows, much of how the application works depends on the DLL files of the program. For instance, if a particular application had several modules, then how each module interacts with each other is determined by the Windows DLL files.

If you want detailed explanation, check these useful resources

Please checkout another answer to similar question here

It depends on what makes the most sense for your case.

Does it make sense to return null, e.g. "no such user exists"?

Or does it make sense to create a default user? This makes the most sense when you can safely assume that if a user DOESN'T exist, the calling code intends for one to exist when they ask for it.

Or does it make sense to throw an exception (a la "FileNotFound") if the calling code is demanding a user with an invalid ID?

However - from a separation of concerns/SRP standpoint, the first two are more correct. And technically the first is the most correct (but only by a hair) - GetUserById should only be responsible for one thing - getting the user. Handling its own "user does not exist" case by returning something else could be a violation of SRP. Separating into a different check - bool DoesUserExist(id) would be appropriate if you do choose to throw an exception.

Based on extensive comments below: if this is an API-level design question, this method could be analogous to "OpenFile" or "ReadEntireFile". We are "opening" a user from some repository and hydrating the object from the resultant data. An exception could be appropriate in this case. It might not be, but it could be.

All approaches are acceptable - it just depends, based on the larger context of the API/application.

I too faced the same issue. I had installed Oracle Express edition 10g in Windows XP OS using VMware and it was working fine. Since it was very awkward typing SQL queries in the SQL utility provided by 10g and since I was used to working with SQL developer, I installed 32 bit SQL developer in XP and tried connecting to my DB SID "XE". But the connection failed with error-ORA-12505 TNS listener doesn't currently know of SID given in connect descriptor. I was at sea as to how this problem occurred since it was working fine with the SQL utility and I had also created few Informatica mappings using the same. I did browse a lot on this stuff hither thither and applied the suggestions offered to me after pinging the status of "lsnrctl" on public forums but to no avail. However, this morning I tried creating a new connection again, and Voila, it worked with no issues. I am guessing after reading in few posts that sometimes listener listens before the DB connects or something(pardon me for my crude reference as I am a newbie here) but I suggest to just restart the machine and check again.

Two options:

for (let item in MotifIntervention) {
    if (isNaN(Number(item))) {
        console.log(item);
    }
}

Or

Object.keys(MotifIntervention).filter(key => !isNaN(Number(MotifIntervention[key])));

(code in playground)

Edit

String enums look different than regular ones, for example:

enum MyEnum {
    A = "a",
    B = "b",
    C = "c"
}

Compiles into:

var MyEnum;
(function (MyEnum) {
    MyEnum["A"] = "a";
    MyEnum["B"] = "b";
    MyEnum["C"] = "c";
})(MyEnum || (MyEnum = {}));

Which just gives you this object:

{
    A: "a",
    B: "b",
    C: "c"
}

You can get all the keys (["A", "B", "C"]) like this:

Object.keys(MyEnum);

And the values (["a", "b", "c"]):

Object.keys(MyEnum).map(key => MyEnum[key])

Or using Object.values():

Object.values(MyEnum)

Your sprite is created mid way through the playerSprite function... it also goes out of scope and ceases to exist at the end of that same function. The sprite must be created where you can pass it to playerSprite to initialize it and also where you can pass it to your draw function.

Perhaps declare it above your first while?

I don't think it's possible unless you use a flash, activex or java uploader.

For security reasons ajax / javascript isn't allowed to access the file stream or file properties before or during upload.

@mywolfe02 gives a static range code so his inRange works fine but if you want to add dynamic range then use this one with inRange function of him.this works better with when you want to populate data to fix starting cell and last column is also fixed.

Sub DynamicRange()

Dim sht As Worksheet
Dim LastRow As Long
Dim StartCell As Range
Dim rng As Range

Set sht = Worksheets("xyz")
LastRow = sht.Cells.Find("*", SearchOrder:=xlByRows, SearchDirection:=xlPrevious).row
Set rng = Workbooks("Record.xlsm").Worksheets("xyz").Range(Cells(12, 2), Cells(LastRow, 12))

Debug.Print LastRow

If InRange(ActiveCell, rng) Then
'        MsgBox "Active Cell In Range!"
  Else
      MsgBox "Please select the cell within the range!"
  End If

End Sub 

Previous answers are correct but here is one more way of doing this and some tips:

Option #1 Go to you Jenkins job and search for "add build step" and then just copy and paste your script there

Option #2 Go to Jenkins and do the same again "add build step" but this time put the fully qualified path for your script in there example : ./usr/somewhere/helloWorld.sh

things to watch for /tips:

• Environment variables, if your job is running at the same time then you need to worry about concurrency issues. One job may be setting the value of environment variables and the next may use the value or take some action based on that incorrectly.
• Make sure all paths are fully qualified
• Think about logging /var/log or somewhere so you would also have something to go to on the server (optional)
• thing about space issue and permissions, running out of space and permission issues are very common in linux environment
• Alerting and make sure your script/job fails the jenkin jobs when your script fails

The -Xmx argument defines the max memory size that the heap can reach for the JVM. You must know your program well and see how it performs under load and set this parameter accordingly. A low value can cause OutOfMemoryExceptions or a very poor performance if your program's heap memory is reaching the maximum heap size. If your program is running in dedicated server you can set this parameter higher because it wont affect other programs.

The -Xms argument sets the initial heap memory size for the JVM. This means that when you start your program the JVM will allocate this amount of memory instantly. This is useful if your program will consume a large amount of heap memory right from the start. This avoids the JVM to be constantly increasing the heap and can gain some performance there. If you don't know if this parameter is going to help you, don't use it.

In summary, this is a compromise that you have to decide based only in the memory behavior of your program.

Please try with below code

var s = "15 Feb 2015 11.30 a.m";
        var times = s.match("((([0-9])|([0-2][0-9])).([0-9][0-9])[\t ]?((a.m|p.m)|(A.M|P.M)))");            
        var time = "";

        if(times != null){                          
            var hour = times[2];
            if((times[6] == "p.m" || times[6] == "P.M")){
                if(hour < 12){
                    hour = parseInt(hour) + parseInt(12);
                }else if(hour == 12){
                    hour = "00";
                }
            }
            time = [hour, times[5], "00"].join(":");

        }

Thanks

To delete an element use the following way:

// declaring and assigning array1 
std:vector<int> array1 {0,2,3,4};

// erasing the value in the array
array1.erase(array1.begin()+n);

For a more broad overview you can visit: http://www.cplusplus.com/reference/vector/vector/erase/

See if the below helps you:

I was using the following earlier:

ClientScript.RegisterClientScriptBlock(Page.GetType(), "AlertMsg", "<script language='javascript'>alert('The Web Policy need to be accepted to submit the new assessor information.');</script>");

After implementing AJAX in this page, it stopped working. After reading your blog, I changed the above to:

ScriptManager.RegisterClientScriptBlock(imgBtnSubmit, this.GetType(), "AlertMsg", "<script language='javascript'>alert('The Web Policy need to be accepted to submit the new assessor information.');</script>", false);

This is working perfectly fine.

(It’s .NET 2.0 Framework, I am using)

ffill now has it's own method pd.DataFrame.ffill

df.ffill()

     0    1    2
0  1.0  2.0  3.0
1  4.0  2.0  3.0
2  4.0  2.0  9.0

This is the perfect kind of field to define as CHAR 36, by the way, not VARCHAR 36, since each value will have the exact same length. And you'll use less storage space, since you don't need to store the data length for each value, just the value.

OP: "I would love if there were a way to do it where I didn't have to know the host address..."

response.writeHead(301, {
  Location: "http" + (request.socket.encrypted ? "s" : "") + "://" + 
    request.headers.host + newRoom
});
response.end();

Put in config.php this

$config['rewrite_short_tags'] = FALSE;

There are several options and none of them are the official correct way and none of them are really incorrect, though they can convey different information to the computer and to others reading your code.

For the given example I think the clearest option would be to supply an identity default value, in this case do something like:

fooBar <- function(x, y=0) {
  x + y
}

This is the shortest of the options shown so far and shortness can help readability (and sometimes even speed in execution). It is clear that what is being returned is the sum of x and y and you can see that y is not given a value that it will be 0 which when added to x will just result in x. Obviously if something more complicated than addition is used then a different identity value will be needed (if one exists).

One thing I really like about this approach is that it is clear what the default value is when using the args function, or even looking at the help file (you don't need to scroll down to the details, it is right there in the usage).

The drawback to this method is when the default value is complex (requiring multiple lines of code), then it would probably reduce readability to try to put all that into the default value and the missing or NULL approaches become much more reasonable.

Some of the other differences between the methods will appear when the parameter is being passed down to another function, or when using the match.call or sys.call functions.

So I guess the "correct" method depends on what you plan to do with that particular argument and what information you want to convey to readers of your code.

Update (2017/01/05):

GitHub has published an update that allows you now to search within commit messages from within their UI. See blog post for more information.

I had the same question and contacted someone GitHub yesterday:

Since they switched their search engine to Elasticsearch it's not possible to search for commit messages using the GitHub UI. But that feature is on the team's wishlist.

Unfortunately there's no release date for that function right now.

I would additionally suggest a 4th option as a better alternative to the proposed options by @zbynour.

Use $rootScope.$emit rather than $rootScope.$broadcast regardless of the relationship between trasmitting and receiving controller. That way, the event remains within the set of $rootScope.$$listeners whereas with $rootScope.$broadcast the event propagates to all children scopes, most of which will probably not be listeners of that event anyway. And of course in the receiving controller's end you just use $rootScope.$on.

For this option you must remember to destroy the controller's rootScope listeners:

var unbindEventHandler = $rootScope.$on('myEvent', myHandler);
$scope.$on('$destroy', function () {
  unbindEventHandler();
});

document.getElementById('myDiv').style.height = 500;

This is the very basic JS code required to adjust the height of your object dynamically. I just did this very thing where I had some auto height property, but when I add some content via XMLHttpRequest I needed to resize my parent div and this offsetheight property did the trick in IE6/7 and FF3

I was able to resolve my clearing my cookies and cache.

You can record a macro that removes the first blank line, and positions the cursor correctly for the second line. Then you can repeat executing that macro.

What is function overloading in general?

Function overloading or method overloading is the ability to create multiple functions of the same name with different implementations (Wikipedia)

What is function overloading in JS?

This feature is not possible in JS - the last defined function is taken in case of multiple declarations:

function foo(a1, a2) { return `${a1}, ${a2}` }
function foo(a1) { return `${a1}` } // replaces above `foo` declaration
foo(42, "foo") // "42"

... and in TS?

Overloads are a compile-time construct with no impact on the JS runtime:

function foo(s: string): string // overload #1 of foo
function foo(s: string, n: number): number // overload #2 of foo
function foo(s: string, n?: number): string | number {/* ... */} // foo implementation

A duplicate implementation error is triggered, if you use above code (safer than JS). TS chooses the first fitting overload in top-down order, so overloads are sorted from most specific to most broad.

Method overloading in TS: a more complex example

Overloaded class method types can be used in a similar way to function overloading:

class LayerFactory {
    createFeatureLayer(a1: string, a2: number): string
    createFeatureLayer(a1: number, a2: boolean, a3: string): number
    createFeatureLayer(a1: string | number, a2: number | boolean, a3?: string)
        : number | string { /*... your implementation*/ }
}

const fact = new LayerFactory()
fact.createFeatureLayer("foo", 42) // string
fact.createFeatureLayer(3, true, "bar") // number

The vastly different overloads are possible, as the function implementation is compatible to all overload signatures - enforced by the compiler.

I spent a while trying to do the same thing, trying to subtract the hours:minutes from datetime - here's how I did it:

convert( varchar, cast((RouteMileage / @average_speed) as integer))+ ':' +  convert( varchar, cast((((RouteMileage / @average_speed) - cast((RouteMileage / @average_speed) as integer)) * 60) as integer)) As TravelTime,

dateadd( n, -60 * CAST( (RouteMileage / @average_speed) AS DECIMAL(7,2)), @entry_date) As DepartureTime 

OUTPUT:

DeliveryDate                TravelTime             DepartureTime
2012-06-02 12:00:00.000       25:49         2012-06-01 10:11:00.000

In addition to the answer by ProGM, in case you see characters in boxes like NUL or ACK and want to get rid of them, those are ASCII control characters (0 to 31), you can find them with the following expression and remove them:

[\x00-\x1F]+

In order to remove all non-ASCII AND ASCII control characters, you should remove all characters matching this regex:

[^\x1F-\x7F]+

ALTER TABLE table_name CONVERT to CHARACTER SET utf8;

Spring-jpa creates the query using the entity manager, and Hibernate will ignore the fetch mode if the query was built by the entity manager.

The following is the work around that I used:

1. Implement a custom repository which inherits from SimpleJpaRepository

2. Override the method getQuery(Specification<T> spec, Sort sort):

   @Override
   protected TypedQuery<T> getQuery(Specification<T> spec, Sort sort) { 
       CriteriaBuilder builder = entityManager.getCriteriaBuilder();
       CriteriaQuery<T> query = builder.createQuery(getDomainClass());
   
       Root<T> root = applySpecificationToCriteria(spec, query);
       query.select(root);
   
       applyFetchMode(root);
   
       if (sort != null) {
           query.orderBy(toOrders(sort, root, builder));
       }
   
       return applyRepositoryMethodMetadata(entityManager.createQuery(query));
   }
   

   In the middle of the method, add applyFetchMode(root); to apply the fetch mode, to make Hibernate create the query with the correct join.

   (Unfortunately we need to copy the whole method and related private methods from the base class because there was no other extension point.)

3. Implement applyFetchMode:

   private void applyFetchMode(Root<T> root) {
       for (Field field : getDomainClass().getDeclaredFields()) {
   
           Fetch fetch = field.getAnnotation(Fetch.class);
   
           if (fetch != null && fetch.value() == FetchMode.JOIN) {
               root.fetch(field.getName(), JoinType.LEFT);
           }
       }
   }
   

I had a similar problem this was my code:

    json_file=json.dumps(pyJson)
    file = open("list.json",'w')
    file.write(json_file)  

    json_file = open("list.json","r")
    json_decoded = json.load(json_file)
    print json_decoded

the problem was i had forgotten to file.close() I did it and fixed the problem.

I don't like to use setTimeout in or even have strange temporary inputs. So I came up with this.

Simply change your password field type to text

<input name="password" type="text" value="">

And when the user focus that input change it again to password

$('input[name=password]').on('focus', function (e) {
    $(e.target).attr('type', 'password');
});

Its working using latest Chrome (Version 54.0.2840.71 (64-bit))

I actually took my time went through all the above answers on this page but to no avail. I just happened to change the owner and the permissions of directory and sub-directories using the following command.I changed the owner of the web project directory in /usr/share/nginx/html to the root user using:

chown root /usr/share/nginx/html/mywebprojectdir/*

And finally changed the permissions of that directory and sub-directories using:

chmod 755 /usr/share/nginx/html/mywebprojectdir/*

NOTE: if denied , you can use sudo

You're looking for the .filter() function:

  $scope.appIds = $scope.applicationsHere.filter(function(obj) {
    return obj.selected;
  });

That'll produce an array that contains only those objects whose "selected" property is true (or truthy).

edit sorry I was getting some coffee and I missed the comments - yes, as jAndy noted in a comment, to filter and then pluck out just the "id" values, it'd be:

  $scope.appIds = $scope.applicationsHere.filter(function(obj) {
    return obj.selected;
  }).map(function(obj) { return obj.id; });

Some functional libraries (like Functional, which in my opinion doesn't get enough love) have a .pluck() function to extract property values from a list of objects, but native JavaScript has a pretty lean set of such tools.

No, that's not possible. The port is not part of the hostname, so it has no meaning in the hosts-file.

int maxAge = context.Persons.Max(p => p.Age);

This version, if the list is empty:

• Returns null - for nullable overloads
• Throws Sequence contains no element exception - for non-nullable overloads

-

int maxAge = context.Persons.Select(p => p.Age).DefaultIfEmpty(0).Max();

This version handles the empty list case, but it generates more complex query, and for some reason doesn't work with EF Core.

-

int maxAge = context.Persons.Max(p => (int?)p.Age) ?? 0;

This version is elegant and performant (simple query and single round-trip to the database), works with EF Core. It handles the mentioned exception above by casting the non-nullable type to nullable and then applying the default value using the ?? operator.

simply add a border: 2px solid #e60000; to your 2nd div tag CSS.

Definitely it works

#Div2Id {
    border: 2px solid #e60000; --> color is your preference
}

1) Check whether mod_rewrite is enabled. Go to /etc/apache2/mods-enabled directory and see whether the rewrite.load is available. If not, enable it using the command sudo a2enmod rewrite.It will enable the rewrite module. If its already enabled, it will show the message Module rewrite already enabled.
2)Create a virtual host for public directory so that instead of giving http://localhost/public/index.php we will be able to use like that http://example.com/index.php. [hence public folder name will be hidded]
3)Then create a .htaccess which will hide the index.php from your url which shoul be inside the root directory (public folder)

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

just close the eclipse and avd emulator and restart it. It works fine

If you're using MS SQL, you can try:

Reading the friendly manual? Who'd want to do that?

start = Time.now
largest_known_fixnum = 1
smallest_known_bignum = nil

until smallest_known_bignum == largest_known_fixnum + 1
  if smallest_known_bignum.nil?
    next_number_to_try = largest_known_fixnum * 1000
  else
    next_number_to_try = (smallest_known_bignum + largest_known_fixnum) / 2 # Geometric mean would be more efficient, but more risky
  end

The answers here got me close, but in 2016, I was able to write the following LINQ:

List<ObjectType> objectList = similarTypeList.Select(o =>
    new ObjectType
    {
        PropertyOne = o.PropertyOne,
        PropertyTwo = o.PropertyTwo,
        PropertyThree = o.PropertyThree
    }).ToList();

To overcome the null / undefined issue, try using the ? operator to check existence:

<p ng-if="post?.capabilities?.items?.length > 0">

• Sidenote, if anyone got to this page looking for an Ionic Framework answer, ensure you use *ngIf:

  <p *ngIf="post?.capabilities?.items?.length > 0">
  

I've tried most of the above and a few others and have found https://appicon.co to be the easiest, fastest, and provides the most comprehensive set.

1. Drag your image onto the screen
2. Click Generate
3. Open the file just downloaded to your Downloads folder

Here, you may be able to drag this entire folder into Xcode. If not:

4. Double-click the Assets.xcassets folder
5. Select all files
6. Drag them to Assets.xcassets
7. Rename it to Appicon

You can also plot the timestamp, value pairs using pyplot.plot (after parsing them from their string representation). (Tested with matplotlib versions 1.2.0 and 1.3.1.)

Example:

import datetime
import random
import matplotlib.pyplot as plt

# make up some data
x = [datetime.datetime.now() + datetime.timedelta(hours=i) for i in range(12)]
y = [i+random.gauss(0,1) for i,_ in enumerate(x)]

# plot
plt.plot(x,y)
# beautify the x-labels
plt.gcf().autofmt_xdate()

plt.show()

Resulting image:

Here's the same as a scatter plot:

import datetime
import random
import matplotlib.pyplot as plt

# make up some data
x = [datetime.datetime.now() + datetime.timedelta(hours=i) for i in range(12)]
y = [i+random.gauss(0,1) for i,_ in enumerate(x)]

# plot
plt.scatter(x,y)
# beautify the x-labels
plt.gcf().autofmt_xdate()

plt.show()

Produces an image similar to this:

• you can use (set wildmenu)
• you can use tab to autocomplete filenames
• you can also use matching, for example :e p*.dat or something like that (like in old' dos)

• you could also :browse confirm e (for a graphical window)

• but you should also probably specify what vim version you're using, and how that thing in emacs works. Maybe we could find you an exact vim alternative.

Douglas Crockford discusses that topic extensively in The Good Parts. He recommends to avoid the new operator to create new objects. Instead he proposes to create customized constructors. For instance:

var mammal = function (spec) {     
   var that = {}; 
   that.get_name = function (  ) { 
      return spec.name; 
   }; 
   that.says = function (  ) { 
      return spec.saying || ''; 
   }; 
   return that; 
}; 

var myMammal = mammal({name: 'Herb'});

In Javascript a function is an object, and can be used to construct objects out of together with the new operator. By convention, functions intended to be used as constructors start with a capital letter. You often see things like:

function Person() {
   this.name = "John";
   return this;
}

var person = new Person();
alert("name: " + person.name);**

In case you forget to use the new operator while instantiating a new object, what you get is an ordinary function call, and this is bound to the global object instead to the new object.

This is possible with CSS3. Just use position: sticky, as seen here.

position: -webkit-sticky; /* Safari & IE */
position: sticky;
top: 0;

Need more than just an (int) via .tag? Use KVC!

You can pass any data you want through the button object itself (by accessing CALayers keyValue dict).

Set your target like this (with the ":")

[myButton addTarget:self action:@selector(buttonTap:) forControlEvents:UIControlEventTouchUpInside];

Add your data(s) to the button itself (well the .layer of the button that is) like this:

NSString *dataIWantToPass = @"this is my data";//can be anything, doesn't have to be NSString
[myButton.layer setValue:dataIWantToPass forKey:@"anyKey"];//you can set as many of these as you'd like too!

Then when the button is tapped you can check it like this:

-(void)buttonTap:(UIButton*)sender{

    NSString *dataThatWasPassed = (NSString *)[sender.layer valueForKey:@"anyKey"];
    NSLog(@"My passed-thru data was: %@", dataThatWasPassed);

}

To match a substring between the first [ and last ], you may use

\[.*\]            # Including open/close brackets
\[(.*)\]          # Excluding open/close brackets (using a capturing group)
(?<=\[).*(?=\])   # Excluding open/close brackets (using lookarounds)

See a regex demo and a regex demo #2.

Use the following expressions to match strings between the closest square brackets:

• Including the brackets:

  • \[[^][]*] - PCRE, Python re/regex, .NET, Golang, POSIX (grep, sed, bash)
  • \[[^\][]*] - ECMAScript (JavaScript, C++ std::regex, VBA RegExp)
  • \[[^\]\[]*] - Java regex
  • \[[^\]\[]*\] - Onigmo (Ruby, requires escaping of brackets everywhere)

• Excluding the brackets:

  • (?<=\[)[^][]*(?=]) - PCRE, Python re/regex, .NET (C#, etc.), ICU (R stringr), JGSoft Software
  • \[([^][]*)] - Bash, Golang - capture the contents between the square brackets with a pair of unescaped parentheses, also see below
  • \[([^\][]*)] - JavaScript, C++ std::regex, VBA RegExp
  • (?<=\[)[^\]\[]*(?=]) - Java regex
  • (?<=\[)[^\]\[]*(?=\]) - Onigmo (Ruby, requires escaping of brackets everywhere)

NOTE: * matches 0 or more characters, use + to match 1 or more to avoid empty string matches in the resulting list/array.

Whenever both lookaround support is available, the above solutions rely on them to exclude the leading/trailing open/close bracket. Otherwise, rely on capturing groups (links to most common solutions in some languages have been provided).

If you need to match nested parentheses, you may see the solutions in the Regular expression to match balanced parentheses thread and replace the round brackets with the square ones to get the necessary functionality. You should use capturing groups to access the contents with open/close bracket excluded:

• \[((?:[^][]++|(?R))*)] - PHP PCRE
• \[((?>[^][]+|(?<o>)\[|(?<-o>]))*)] - .NET demo
• \[(?:[^\]\[]++|(\g<0>))*\] - Onigmo (Ruby) demo

For 3-D visualization pythreejs is the best way to go probably in the notebook. It leverages the interactive widget infrastructure of the notebook, so connection between the JS and python is seamless.

A more advanced library is bqplot which is a d3-based interactive viz library for the iPython notebook, but it only does 2D

The first is better. If you try to debug the second and look at the call stack you won't see where the original exception came from. There are tricks to keep the call-stack intact (try search, it's been answered before) if you really need to rethrow.

You can also create a public method on the page then call that from the code-in-front.

e.g. if using C#:

public string ProcessMyDataItem(object myValue)
{
  if (myValue == null)
  {
     return "0 value";
  }

  return myValue.ToString();
}

Then the label in the code-in-front will be something like:

<asp:Label ID="Label18" Text='<%# ProcessMyDataItem(Eval("item")) %>' runat="server"></asp:Label>

Sorry, haven't tested this code so can't guarantee I got the syntax of "<%# ProcessMyDataItem(Eval("item")) %>" entirely correct.

Oftentimes in Ruby, you don't actually care what the object's class is, per se, you just care that it responds to a certain method. This is known as Duck Typing and you'll see it in all sorts of Ruby codebases.

So in many (if not most) cases, its best to use Duck Typing using #respond_to?(method):

object.respond_to?(:to_i)

Please try this one works for me:

<ImageView android:id="@+id/image_view"     
  android:layout_width="wrap_content"  
  android:layout_height="wrap_content"  
  android:adjustViewBounds="true"  
  android:maxWidth="60dp" 
  android:layout_gravity="center" 
  android:maxHeight="60dp"  
  android:scaleType="fitCenter"  
  android:src="@drawable/icon"  
  /> 

We are using git-repo to manage our multiple GIT repositories. There is also a Jenkins Repo plugin that allows to checkout all or part of the repositories managed by git-repo to the same Jenkins job workspace.

For those looking for a solution. If you accidentally made pip requirements with pip list instead of pip freeze, and want to convert into pip freeze format. I wrote this R script to do so.

library(tidyverse)

pip_list = read_lines("requirements.txt")

pip_freeze = pip_list %>%
  str_replace_all(" \\(", "==") %>%
  str_replace_all("\\)$", "")

pip_freeze %>% write_lines("requirements.txt")

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

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

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

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

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

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

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

And for the controller:-

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

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

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

SELECT * FROM employees WHERE name NOT IN (SELECT name FROM eotm_dyn)

OR

SELECT * FROM employees WHERE NOT EXISTS (SELECT * FROM eotm_dyn WHERE eotm_dyn.name = employees.name)

OR

SELECT * FROM employees LEFT OUTER JOIN eotm_dyn ON eotm_dyn.name = employees.name WHERE eotm_dyn IS NULL

Unfortuantely, as div elements can't be direct descendants of table elements, the way I know to do this is to apply the CSS rules you want to each tr element that you want to apply it to.

<table>
<tr><th>Test Table</th><tr>
<tr><td>123456789</td><tr>
<tr style="display: none; other-property: value;"><td>123456789</td><tr>
<tr style="display: none; other-property: value;"><td>123456789</td><tr>
<tr><td>123456789</td><tr>
<tr><td>123456789</td><tr>
</table>

If you have more than one CSS rule to apply to the rows in question, give the applicable rows a class instead and offload the rules to external CSS.

<table>
<tr><th>Test Table</th><tr>
<tr><td>123456789</td><tr>
<tr class="something"><td>123456789</td><tr>
<tr class="something"><td>123456789</td><tr>
<tr><td>123456789</td><tr>
<tr><td>123456789</td><tr>
</table>

You have your slash backwards, it should be "\n"

HTML5 + spark-md5 and Q

Assuming your'e using a modern browser (that supports HTML5 File API), here's how you calculate the MD5 Hash of a large file (it will calculate the hash on variable chunks)

function calculateMD5Hash(file, bufferSize) {
  var def = Q.defer();

  var fileReader = new FileReader();
  var fileSlicer = File.prototype.slice || File.prototype.mozSlice || File.prototype.webkitSlice;
  var hashAlgorithm = new SparkMD5();
  var totalParts = Math.ceil(file.size / bufferSize);
  var currentPart = 0;
  var startTime = new Date().getTime();

  fileReader.onload = function(e) {
    currentPart += 1;

    def.notify({
      currentPart: currentPart,
      totalParts: totalParts
    });

    var buffer = e.target.result;
    hashAlgorithm.appendBinary(buffer);

    if (currentPart < totalParts) {
      processNextPart();
      return;
    }

    def.resolve({
      hashResult: hashAlgorithm.end(),
      duration: new Date().getTime() - startTime
    });
  };

  fileReader.onerror = function(e) {
    def.reject(e);
  };

  function processNextPart() {
    var start = currentPart * bufferSize;
    var end = Math.min(start + bufferSize, file.size);
    fileReader.readAsBinaryString(fileSlicer.call(file, start, end));
  }

  processNextPart();
  return def.promise;
}

function calculate() {

  var input = document.getElementById('file');
  if (!input.files.length) {
    return;
  }

  var file = input.files[0];
  var bufferSize = Math.pow(1024, 2) * 10; // 10MB

  calculateMD5Hash(file, bufferSize).then(
    function(result) {
      // Success
      console.log(result);
    },
    function(err) {
      // There was an error,
    },
    function(progress) {
      // We get notified of the progress as it is executed
      console.log(progress.currentPart, 'of', progress.totalParts, 'Total bytes:', progress.currentPart * bufferSize, 'of', progress.totalParts * bufferSize);
    });
}

You need to use the CSS white-space attribute.

In particular, white-space: nowrap and white-space: pre are the most commonly used values. The first one seems to be what you 're after.

if you have the BluetoothDevice object you can create bond(pair) from api 19 onwards with bluetoothDevice.createBond() method.

Edit

for callback, if the request was accepted or denied you will have to create a BroadcastReceiver with BluetoothDevice.ACTION_BOND_STATE_CHANGED action

Yes, ensure is called in any circumstances. For more information see "Exceptions, Catch, and Throw" of the Programming Ruby book and search for "ensure".

Precompiled Header (pch) use is a two-step process.

In step one, you compile a stub file (In VS200x it's usually called stdafx.cpp. Newer versions use pch.cpp.). This stub file indirectly includes only the headers you want precompiled. Typically, one small header (usually stdafx.h or pch.hpp) lists standard headers such as <iostream> and <string>, and this is then included in the stub file. Compiling this creates the .pch file.

In step 2, your actual source code includes the same small header from step 1 as the first header. The compiler, when it encounters this special header, reads the corresponding .pch file instead. That means it doesn't have to (re)compile those standard headers every time.

In your case, it seems step 1 fails. Is the stub file still present? In your case, that would probably be xxxxx.cpp. It must be a file that's compiled with /Yc:xxxxx.pch, since that's the compiler flag to indicate it's step 1 of the PCH process. If xxxxx.cpp is present, and is such a stub file, then it's probably missing its /Yc: compiler option.

Lets look at some test cases - try running the following expressions in your JS console:

"a" < "b"

"aa" < "ab"

"aaa" < "aab"

All return true.

JavaScript compares strings character by character and "a" comes before "b" in the alphabet - hence less than.

In your case it works like so -

1 . "a?aaa" < "?a?b"

compares the first two "a" characters - all equal, lets move to the next character.

2 . "a?a??aa" < "a?b??"

compares the second characters "a" against "b" - whoop! "a" comes before "b". Returns true.

youmap.animateCamera(CameraUpdateFactory.newLatLngZoom(currentlocation, 16));

16 is the zoom level

move and del ARE certainly the equivalents, but from a functionality standpoint they are woefully NOT equivalent. For example, you can't move both files AND folders (in a wildcard scenario) with the move command. And the same thing applies with del.

The preferred solution in my view is to use Win32 ports of the Linux tools, the best collection of which I have found being here.

mv and rm are in the CoreUtils package and they work wonderfully!

You can simply use the toCharArray() to convert a string to char array:

    Scanner s=new Scanner(System.in);
    System.out.print("Enter some String:");
    String str=s.nextLine();
    char a[]=str.toCharArray();

look at last one

t = pd.DataFrame({'a': range(0, 10000), 'b': range(10000, 20000)})
B = []
C = []
A = time.time()
for i,r in t.iterrows():
    C.append((r['a'], r['b']))
B.append(round(time.time()-A,5))

C = []
A = time.time()
for ir in t.itertuples():
    C.append((ir[1], ir[2]))    
B.append(round(time.time()-A,5))

C = []
A = time.time()
for r in zip(t['a'], t['b']):
    C.append((r[0], r[1]))
B.append(round(time.time()-A,5))

C = []
A = time.time()
for r in range(len(t)):
    C.append((t.loc[r, 'a'], t.loc[r, 'b']))
B.append(round(time.time()-A,5))

C = []
A = time.time()

Very few posts suggest using LOGON_TYPE_NEW_CREDENTIALS instead of LOGON_TYPE_NETWORK or LOGON_TYPE_INTERACTIVE. I had an impersonation issue with one machine connected to a domain and one not, and this fixed it. The last code snippet in this post suggests that impersonating across a forest does work, but it doesn't specifically say anything about trust being set up. So this may be worth trying:

const int LOGON_TYPE_NEW_CREDENTIALS = 9;
const int LOGON32_PROVIDER_WINNT50 = 3;
bool returnValue = LogonUser(user, domain, password,
            LOGON_TYPE_NEW_CREDENTIALS, LOGON32_PROVIDER_WINNT50,
            ref tokenHandle);

MSDN says that LOGON_TYPE_NEW_CREDENTIALS only works when using LOGON32_PROVIDER_WINNT50.

RequireJS implements the AMD API (source).

CommonJS is a way of defining modules with the help of an exports object, that defines the module contents. Simply put, a CommonJS implementation might work like this:

// someModule.js
exports.doSomething = function() { return "foo"; };

//otherModule.js
var someModule = require('someModule'); // in the vein of node    
exports.doSomethingElse = function() { return someModule.doSomething() + "bar"; };

Basically, CommonJS specifies that you need to have a require() function to fetch dependencies, an exports variable to export module contents and a module identifier (which describes the location of the module in question in relation to this module) that is used to require the dependencies (source). CommonJS has various implementations, including Node.js, which you mentioned.

CommonJS was not particularly designed with browsers in mind, so it doesn't fit in the browser environment very well (I really have no source for this--it just says so everywhere, including the RequireJS site.) Apparently, this has something to do with asynchronous loading, etc.

On the other hand, RequireJS implements AMD, which is designed to suit the browser environment (source). Apparently, AMD started as a spinoff of the CommonJS Transport format and evolved into its own module definition API. Hence the similarities between the two. The new feature in AMD is the define() function that allows the module to declare its dependencies before being loaded. For example, the definition could be:

define('module/id/string', ['module', 'dependency', 'array'], 
function(module, factory function) {
  return ModuleContents;  
});

So, CommonJS and AMD are JavaScript module definition APIs that have different implementations, but both come from the same origins.

• AMD is more suited for the browser, because it supports asynchronous loading of module dependencies.
• RequireJS is an implementation of AMD, while at the same time trying to keep the spirit of CommonJS (mainly in the module identifiers).

To confuse you even more, RequireJS, while being an AMD implementation, offers a CommonJS wrapper so CommonJS modules can almost directly be imported for use with RequireJS.

define(function(require, exports, module) {
  var someModule = require('someModule'); // in the vein of node    
  exports.doSomethingElse = function() { return someModule.doSomething() + "bar"; };
});

I hope this helps to clarify things!

The problem was that I had hexadecimal data that needed to be converted to binary before being base64encoded.

in PHP:

base64_encode(pack("H*", $subvalue))

I give my solution for Mac:

1. With your device connected to the USB port, open a terminal and go to the adb folder.
2. Write: ./adb devices
3. The terminal will show something like this: List of devices attached 36ac5997 device
4. Take note of the serial number (36ac5997)
5. Write: ./adb -s 36ac5997 to connect to the device
6. Write: ./adb logcat

If at any time you want to clear the log, type ./adb logcat -c

A deleted function is implicitly inline

(Addendum to existing answers)

... And a deleted function shall be the first declaration of the function (except for deleting explicit specializations of function templates - deletion should be at the first declaration of the specialization), meaning you cannot declare a function and later delete it, say, at its definition local to a translation unit.

Citing [dcl.fct.def.delete]/4:

A deleted function is implicitly inline. ( Note: The one-definition rule ([basic.def.odr]) applies to deleted definitions. — end note ] A deleted definition of a function shall be the first declaration of the function or, for an explicit specialization of a function template, the first declaration of that specialization. [ Example:

struct sometype {
  sometype();
};
sometype::sometype() = delete;      // ill-formed; not first declaration

— end example )

A primary function template with a deleted definition can be specialized

Albeit a general rule of thumb is to avoid specializing function templates as specializations do not participate in the first step of overload resolution, there are arguable some contexts where it can be useful. E.g. when using a non-overloaded primary function template with no definition to match all types which one would not like implicitly converted to an otherwise matching-by-conversion overload; i.e., to implicitly remove a number of implicit-conversion matches by only implementing exact type matches in the explicit specialization of the non-defined, non-overloaded primary function template.

Before the deleted function concept of C++11, one could do this by simply omitting the definition of the primary function template, but this gave obscure undefined reference errors that arguably gave no semantic intent whatsoever from the author of primary function template (intentionally omitted?). If we instead explicitly delete the primary function template, the error messages in case no suitable explicit specialization is found becomes much nicer, and also shows that the omission/deletion of the primary function template's definition was intentional.

#include <iostream>
#include <string>

template< typename T >
void use_only_explicit_specializations(T t);

template<>
void use_only_explicit_specializations<int>(int t) {
    std::cout << "int: " << t;
}

int main()
{
    const int num = 42;
    const std::string str = "foo";
    use_only_explicit_specializations(num);  // int: 42
    //use_only_explicit_specializations(str); // undefined reference to `void use_only_explicit_specializations< ...
}

However, instead of simply omitting a definition for the primary function template above, yielding an obscure undefined reference error when no explicit specialization matches, the primary template definition can be deleted:

#include <iostream>
#include <string>

template< typename T >
void use_only_explicit_specializations(T t) = delete;

template<>
void use_only_explicit_specializations<int>(int t) {
    std::cout << "int: " << t;
}

int main()
{
    const int num = 42;
    const std::string str = "foo";
    use_only_explicit_specializations(num);  // int: 42
    use_only_explicit_specializations(str);
    /* error: call to deleted function 'use_only_explicit_specializations' 
       note: candidate function [with T = std::__1::basic_string<char>] has 
       been explicitly deleted
       void use_only_explicit_specializations(T t) = delete; */
}

Yielding a more more readable error message, where the deletion intent is also clearly visible (where an undefined reference error could lead to the developer thinking this an unthoughtful mistake).

Returning to why would we ever want to use this technique? Again, explicit specializations could be useful to implicitly remove implicit conversions.

#include <cstdint>
#include <iostream>

void warning_at_best(int8_t num) { 
    std::cout << "I better use -Werror and -pedantic... " << +num << "\n";
}

template< typename T >
void only_for_signed(T t) = delete;

template<>
void only_for_signed<int8_t>(int8_t t) {
    std::cout << "UB safe! 1 byte, " << +t << "\n";
}

template<>
void only_for_signed<int16_t>(int16_t t) {
    std::cout << "UB safe! 2 bytes, " << +t << "\n";
}

int main()
{
    const int8_t a = 42;
    const uint8_t b = 255U;
    const int16_t c = 255;
    const float d = 200.F;

    warning_at_best(a); // 42
    warning_at_best(b); // implementation-defined behaviour, no diagnostic required
    warning_at_best(c); // narrowing, -Wconstant-conversion warning
    warning_at_best(d); // undefined behaviour!

    only_for_signed(a);
    only_for_signed(c);

    //only_for_signed(b);  
    /* error: call to deleted function 'only_for_signed' 
       note: candidate function [with T = unsigned char] 
             has been explicitly deleted
       void only_for_signed(T t) = delete; */

    //only_for_signed(d);
    /* error: call to deleted function 'only_for_signed' 
       note: candidate function [with T = float] 
             has been explicitly deleted
       void only_for_signed(T t) = delete; */
}

Use bases if you just want to get the parents, use __mro__ (as pointed out by @naught101) for getting the method resolution order (so to know in which order the init's were executed).

Bases (and first getting the class for an existing object):

>>> some_object = "some_text"
>>> some_object.__class__.__bases__
(object,)

For mro in recent Python versions:

>>> some_object = "some_text"
>>> some_object.__class__.__mro__
(str, object)

Obviously, when you already have a class definition, you can just call __mro__ on that directly:

>>> class A(): pass
>>> A.__mro__
(__main__.A, object)

The color for your buttons comes from the btn-x classes (e.g., btn-primary, btn-success), so if you want to manually change the colors by writing your own custom css rules, you'll need to change:

/*This is modifying the btn-primary colors but you could create your own .btn-something class as well*/
.btn-primary {
    color: #fff;
    background-color: #0495c9;
    border-color: #357ebd; /*set the color you want here*/
}
.btn-primary:hover, .btn-primary:focus, .btn-primary:active, .btn-primary.active, .open>.dropdown-toggle.btn-primary {
    color: #fff;
    background-color: #00b3db;
    border-color: #285e8e; /*set the color you want here*/
}

Edit 1

As pointed out in comments, the code in the original answer keeps running the timer even after the promise is resolved/rejected.

The code below fixes that issue.

function timeout(ms, promise) {
  return new Promise((resolve, reject) => {
    const timer = setTimeout(() => {
      reject(new Error('TIMEOUT'))
    }, ms)

    promise
      .then(value => {
        clearTimeout(timer)
        resolve(value)
      })
      .catch(reason => {
        clearTimeout(timer)
        reject(reason)
      })
  })
}

Original answer

It doesn't have a specified default; the specification doesn't discuss timeouts at all.

You can implement your own timeout wrapper for promises in general:

// Rough implementation. Untested.
function timeout(ms, promise) {
  return new Promise(function(resolve, reject) {
    setTimeout(function() {
      reject(new Error("timeout"))
    }, ms)
    promise.then(resolve, reject)
  })
}

timeout(1000, fetch('/hello')).then(function(response) {
  // process response
}).catch(function(error) {
  // might be a timeout error
})

As described in https://github.com/github/fetch/issues/175 Comment by https://github.com/mislav

I'm not sure I really understood what you want to do, but the suggested way to communicate between fragments is to use callbacks with the Activity, never directly between fragments. See here http://developer.android.com/training/basics/fragments/communicating.html

You don't really need a sub-select:

SELECT a, COUNT(*) AS b,
   SUM( CASE WHEN c = 'const' THEN 1 ELSE 0 END ) as d,
   from t group by a order by b desc

Just use the classic == operator:

>>> [0,1,2] == [0,1,2]
True
>>> [0,1,2] == [0,2,1]
False
>>> [0,1] == [0,1,2]
False

Lists are equal if elements at the same index are equal. Ordering is taken into account then.

The input in the markup is missing "type", the input (text I assume) has the attribute name="name" and ID="cname", the provided code by Ayo calls the input named "cname"* where it should be "name".

actually you should only put in-line elements inside the p, so in your case ol is better outside

After struggling a bit with some of the answers here, I found a library called backoff that worked better for my situation. A basic example:

import backoff

@backoff.on_exception(
    backoff.expo,
    requests.exceptions.RequestException,
    max_tries=5,
    giveup=lambda e: e.response is not None and e.response.status_code < 500
)
def publish(self, data):
    r = requests.post(url, timeout=10, json=data)
    r.raise_for_status()

I'd still recommend giving the library's native functionality a shot, but if you run into any problems or need broader control, backoff is an option.

If you can't hold all the items in memory at once, this problem becomes much harder. The heap solution requires you to hold all the elements in memory at once. This is not possible in most real world applications of this problem.

Instead, as you see numbers, keep track of the count of the number of times you see each integer. Assuming 4 byte integers, that's 2^32 buckets, or at most 2^33 integers (key and count for each int), which is 2^35 bytes or 32GB. It will likely be much less than this because you don't need to store the key or count for those entries that are 0 (ie. like a defaultdict in python). This takes constant time to insert each new integer.

Then at any point, to find the median, just use the counts to determine which integer is the middle element. This takes constant time (albeit a large constant, but constant nonetheless).

If all you want is to invoke foo, and you prefer to propagate the exception as is (without wrapping), you can also just use Java's for loop instead (after turning the Stream into an Iterable with some trickery):

for (A a : (Iterable<A>) as::iterator) {
   a.foo();
}

This is, at least, what I do in my JUnit tests, where I don't want to go through the trouble of wrapping my checked exceptions (and in fact prefer my tests to throw the unwrapped original ones)

The problem is in your playerMovement method. You are creating the string name of your room variables (ID1, ID2, ID3):

letsago = "ID" + str(self.dirDesc.values())

However, what you create is just a str. It is not the variable. Plus, I do not think it is doing what you think its doing:

>>>str({'a':1}.values())
'dict_values([1])'

If you REALLY needed to find the variable this way, you could use the eval function:

>>>foo = 'Hello World!'
>>>eval('foo')
'Hello World!'

or the globals function:

class Foo(object):
    def __init__(self):
        super(Foo, self).__init__()
    def test(self, name):

However, instead I would strongly recommend you rethink you class(es). Your userInterface class is essentially a Room. It shouldn't handle player movement. This should be within another class, maybe GameManager or something like that.

EDIT_ADD: If Will Ness is correct that the question's purpose is just to output a continuous stream of primes for as long as the program is run (pressing Pause/Break to pause and any key to start again) with no serious hope of every getting to that upper limit, then the code should be written with no upper limit argument and a range check of "true" for the first 'i' for loop. On the other hand, if the question wanted to actually print the primes up to a limit, then the following code will do the job much more efficiently using Trial Division only for odd numbers, with the advantage that it doesn't use memory at all (it could also be converted to a continuous loop as per the above):

static void primesttt(ulong top_number) {
  Console.WriteLine("Prime:  2");
  for (var i = 3UL; i <= top_number; i += 2) {
    var isPrime = true;
    for (uint j = 3u, lim = (uint)Math.Sqrt((double)i); j <= lim; j += 2) {
      if (i % j == 0)  {
        isPrime = false;
        break;
      }
    }
    if (isPrime) Console.WriteLine("Prime:  {0} ", i);
  }
}

First, the question code produces no output because of that its loop variables are integers and the limit tested is a huge long integer, meaning that it is impossible for the loop to reach the limit producing an inner loop EDITED: whereby the variable 'j' loops back around to negative numbers; when the 'j' variable comes back around to -1, the tested number fails the prime test because all numbers are evenly divisible by -1 END_EDIT. Even if this were corrected, the question code produces very slow output because it gets bound up doing 64-bit divisions of very large quantities of composite numbers (all the even numbers plus the odd composites) by the whole range of numbers up to that top number of ten raised to the sixteenth power for each prime that it can possibly produce. The above code works because it limits the computation to only the odd numbers and only does modulo divisions up to the square root of the current number being tested.

This takes an hour or so to display the primes up to a billion, so one can imagine the amount of time it would take to show all the primes to ten thousand trillion (10 raised to the sixteenth power), especially as the calculation gets slower with increasing range. END_EDIT_ADD

Although the one liner (kind of) answer by @SLaks using Linq works, it isn't really the Sieve of Eratosthenes as it is just an unoptimised version of Trial Division, unoptimised in that it does not eliminate odd primes, doesn't start at the square of the found base prime, and doesn't stop culling for base primes larger than the square root of the top number to sieve. It is also quite slow due to the multiple nested enumeration operations.

It is actually an abuse of the Linq Aggregate method and doesn't effectively use the first of the two Linq Range's generated. It can become an optimized Trial Division with less enumeration overhead as follows:

static IEnumerable<int> primes(uint top_number) {
  var cullbf = Enumerable.Range(2, (int)top_number).ToList();
  for (int i = 0; i < cullbf.Count; i++) {
    var bp = cullbf[i]; var sqr = bp * bp; if (sqr > top_number) break;
    cullbf.RemoveAll(c => c >= sqr && c % bp == 0);
  } return cullbf; }

which runs many times faster than the SLaks answer. However, it is still slow and memory intensive due to the List generation and the multiple enumerations as well as the multiple divide (implied by the modulo) operations.

The following true Sieve of Eratosthenes implementation runs about 30 times faster and takes much less memory as it only uses a one bit representation per number sieved and limits its enumeration to the final iterator sequence output, as well having the optimisations of only treating odd composites, and only culling from the squares of the base primes for base primes up to the square root of the maximum number, as follows:

static IEnumerable<uint> primes(uint top_number) {
  if (top_number < 2u) yield break;
  yield return 2u; if (top_number < 3u) yield break;
  var BFLMT = (top_number - 3u) / 2u;
  var SQRTLMT = ((uint)(Math.Sqrt((double)top_number)) - 3u) / 2u;
  var buf = new BitArray((int)BFLMT + 1,true);
  for (var i = 0u; i <= BFLMT; ++i) if (buf[(int)i]) {
      var p = 3u + i + i; if (i <= SQRTLMT) {
        for (var j = (p * p - 3u) / 2u; j <= BFLMT; j += p)
          buf[(int)j] = false; } yield return p; } }

The above code calculates all the primes to ten million range in about 77 milliseconds on an Intel i7-2700K (3.5 GHz).

Either of the two static methods can be called and tested with the using statements and with the static Main method as follows:

using System;
using System.Collections;
using System.Collections.Generic;
using System.Linq;

static void Main(string[] args) {
  Console.WriteLine("This program generates prime sequences.\r\n");

  var n = 10000000u;

  var elpsd = -DateTime.Now.Ticks;

  var count = 0; var lastp = 0u;
  foreach (var p in primes(n)) { if (p > n) break; ++count; lastp = (uint)p; }

  elpsd += DateTime.Now.Ticks;
  Console.WriteLine(
    "{0} primes found <= {1}; the last one is {2} in {3} milliseconds.",
    count, n, lastp,elpsd / 10000);

  Console.Write("\r\nPress any key to exit:");
  Console.ReadKey(true);
  Console.WriteLine();
}

which will show the number of primes in the sequence up to the limit, the last prime found, and the time expended in enumerating that far.

EDIT_ADD: However, in order to produce an enumeration of the number of primes less than ten thousand trillion (ten to the sixteenth power) as the question asks, a segmented paged approach using multi-core processing is required but even with C++ and the very highly optimized PrimeSieve, this would require something over 400 hours to just produce the number of primes found, and tens of times that long to enumerate all of them so over a year to do what the question asks. To do it using the un-optimized Trial Division algorithm attempted, it will take super eons and a very very long time even using an optimized Trial Division algorithm as in something like ten to the two millionth power years (that's two million zeros years!!!).

It isn't much wonder that his desktop machine just sat and stalled when he tried it!!!! If he had tried a smaller range such as one million, he still would have found it takes in the range of seconds as implemented.

The solutions I post here won't cut it either as even the last Sieve of Eratosthenes one will require about 640 Terabytes of memory for that range.

That is why only a page segmented approach such as that of PrimeSieve can handle this sort of problem for the range as specified at all, and even that requires a very long time, as in weeks to years unless one has access to a super computer with hundreds of thousands of cores. END_EDIT_ADD

The SQL query SHOW VARIABLES WHERE Variable_name = 'hostname' will show you the hostname of the MySQL server which you can easily resolve to its IP address.

SHOW VARIABLES WHERE Variable_name = 'port' Will give you the port number.

You can find details about this in MySQL's manual: 12.4.5.41. SHOW VARIABLES Syntax and 5.1.4. Server System Variables

As cardern has said list will do the job.

Here is how you can use a named range.

Select your range and enter a new name:

Select your cell that you want a drop down to be in and goto data tab -> data validation.

Select 'List' from the 'Allow' Drop down menu.

Enter your named range like this:

Now you have a drop down linked to your range. If you insert new rows in your range everything will update automatically.

Create a list with type<DataRow> by extend the datatable with AsEnumerable call.

var mylist = dt.AsEnumerable().ToList();

Cheers!! Happy Coding

The MemoryError exception that you are seeing is the direct result of running out of available RAM. This could be caused by either the 2GB per program limit imposed by Windows (32bit programs), or lack of available RAM on your computer. (This link is to a previous question).

You should be able to extend the 2GB by using 64bit copy of Python, provided you are using a 64bit copy of windows.

The IndexError would be caused because Python hit the MemoryError exception before calculating the entire array. Again this is a memory issue.

To get around this problem you could try to use a 64bit copy of Python or better still find a way to write you results to file. To this end look at numpy's memory mapped arrays.

You should be able to run you entire set of calculation into one of these arrays as the actual data will be written disk, and only a small portion of it held in memory.

Have you tried with a sub-query for every field:

UPDATE
    MasterTbl
SET
    TotalX = (SELECT SUM(X) from DetailTbl where DetailTbl.MasterID = MasterTbl.ID),
    TotalY = (SELECT SUM(Y) from DetailTbl where DetailTbl.MasterID = MasterTbl.ID),
    TotalZ = (SELECT SUM(Z) from DetailTbl where DetailTbl.MasterID = MasterTbl.ID)
WHERE
    ....

Basic JavaScript:

if (document.getElementById("elementId").style.display == 'block') { 
  alert('this Element is block'); 
}

Check file permissions.

I had exactly the same error on a Linux machine with the wrong permissions set.

chmod 755 myfile.pl

solved the problem.

The ideal way is not to use ioutil.ReadAll, but rather use a decoder on the reader directly. Here's a nice function that gets a url and decodes its response onto a target structure.

var myClient = &http.Client{Timeout: 10 * time.Second}

func getJson(url string, target interface{}) error {
    r, err := myClient.Get(url)
    if err != nil {
        return err
    }
    defer r.Body.Close()

    return json.NewDecoder(r.Body).Decode(target)
}

Example use:

type Foo struct {
    Bar string
}

func main() {
    foo1 := new(Foo) // or &Foo{}
    getJson("http://example.com", foo1)
    println(foo1.Bar)

    // alternately:

    foo2 := Foo{}
    getJson("http://example.com", &foo2)
    println(foo2.Bar)
}

You should not be using the default *http.Client structure in production as this answer originally demonstrated! (Which is what http.Get/etc call to). The reason is that the default client has no timeout set; if the remote server is unresponsive, you're going to have a bad day.

Execute following command:

set PATH="C:\Program Files (x86)\Java\jre7"

(whichever JRE exists in case of 64bit).

Because your Java Path is not set so you can just do this at command line and then execute the keytool import command.

Some other ideas not mentioned yet:

switch(true){ 
  case in_array($p, array('home', '')): 
    $current_home = 'current'; break;

  case preg_match('/^users\.(online|location|featured|new|browse|search|staff)$/', $p):
    $current_users = 'current'; break;

  case 'forum' == $p:
    $current_forum = 'current'; break; 
}

Someone will probably complain about readability issues with #2, but I would have no problem inheriting code like that.

    $myarray = array_filter($myarray, 'strlen');  //removes null values but leaves "0"
    $myarray = array_filter($myarray);            //removes all null values

DataTable dt;   // datatable should contains datacolumns with Id,Name

List<Employee> employeeList=new List<Employee>();  // Employee should contain  EmployeeId, EmployeeName as properties

foreach (DataRow dr in dt.Rows)
{
    employeeList.Add(new Employee{EmployeeId=dr.Id,EmplooyeeName=dr.Name});
}

None of the above solutions worked for me on Windows 8

But the following command works fine

SHIFT + Q

It needs to be clarified that not only data should be cache-friendly, it is just as important for the code. This is in addition to branch predicition, instruction reordering, avoiding actual divisions and other techniques.

Typically the denser the code, the fewer cache lines will be required to store it. This results in more cache lines being available for data.

The code should not call functions all over the place as they typically will require one or more cache lines of their own, resulting in fewer cache lines for data.

A function should begin at a cache line-alignment-friendly address. Though there are (gcc) compiler switches for this be aware that if the the functions are very short it might be wasteful for each one to occupy an entire cache line. For example, if three of the most often used functions fit inside one 64 byte cache line, this is less wasteful than if each one has its own line and results in two cache lines less available for other usage. A typical alignment value could be 32 or 16.

So spend some extra time to make the code dense. Test different constructs, compile and review the generated code size and profile.

Based on this comment from the OP, "I found the problem. apparentlyworksheet.Cells[y + 1, x + 1].HorizontalAlignment", I believe the real explanation is that all the cells start off sharing the same Style object. So if you change that style object, it changes all the cells that use it. But if you just change the cell's alignment property directly, only that cell is affected.

1. insert is not a recommended way - it is one of the ways to insert into map. The difference with operator[] is that the insert can tell whether the element is inserted into the map. Also, if your class has no default constructor, you are forced to use insert.
2. operator[] needs the default constructor because the map checks if the element exists. If it doesn't then it creates one using default constructor and returns a reference (or const reference to it).

Because map containers do not allow for duplicate key values, the insertion operation checks for each element inserted whether another element exists already in the container with the same key value, if so, the element is not inserted and its mapped value is not changed in any way.

you can use command

date | awk '{print $4}'| cut -d ':' -f3

as you mentioned using only the date|awk '{print $4}' pipeline gives you something like this

20:18:19

so as we can see if we want to extract some part of this string then we need a delimiter , for our case it is :, so we decide to chop on the basis of :. Now this delimiter will chop the string into three parts i.e. 20 ,18 and 19 , as we want the second one we use -f2 in our command. to sum up ,

cut : chops some string based on delimeter.

-d : delimeter (here :)

-f2 : the chopped off token that we want.

The preferred way to get the length of any python object is to pass it as an argument to the len function. Internally, python will then try to call the special __len__ method of the object that was passed.

You should use the string replace function, with a single regex. Assuming by special characters, you mean anything that's not letter, here is a solution:

const str = "abc's test#s";_x000D_
console.log(str.replace(/[^a-zA-Z ]/g, ""));

I use a JavaScript port of the Mersenne Twister: https://gist.github.com/300494 It allows you to set the seed manually. Also, as mentioned in other answers, the Mersenne Twister is a really good PRNG.

The following command worked for me using the command prompt (As an Administrator) in Windows:

mysqlcheck -u root -p -A --auto-repair

Run mysqlcheck with the root user, prompt for a password, check all databases, and auto-repair any corrupted tables.

As mentioned, the C compiler will add padding for alignment requirements. These requirements often have to do with the memory subsystem. Some types of computers can only access memory lined up to some 'nice' value, like 4 bytes. This is often the same as the word length. Thus, the C compiler may align fields in your structure to this value to make them easier to access (e.g., 4 byte values should be 4 byte aligned) Further, it may pad the bottom of the structure to line up data which follows the structure. I believe there are other reasons as well. More info can be found at this wikipedia page.

If nobody has pulled it, you can probably do something like

git push remote +branch^1:remotebranch

which will forcibly update the remote branch to the last but one commit of your branch.

i++: In this scenario first the value is assigned and then increment happens.

++i: In this scenario first the increment is done and then value is assigned

Below is the image visualization and also here is a nice practical video which demonstrates the same.

Another idea is to do myVar.split(',')[1];

For simple case, not using a regexp is a good idea...

I had a button where the background-image had a shadow below it so the text alignment was off from the top. Changing the line-height wouldn't help. I added padding-bottom to it and it worked.

So what you have to do is determine the line-height you want to play with. So, for example, if I have a button who's height is truly 90px but I want the line-height to be 80px I would have something like this:

input[type=butotn].mybutton{
    background: url(my/image.png) no-repeat center top; /*Image is 90px x 150px*/
    width: 150px;
    height: 80px; /*shadow at the bottom is 10px (90px-10px)*/
    padding-bottom: 10px; /*the padding will make up for the lost height while maintaining the line-height to the proper height */

}

I hope this helps.

With version 2.3.4, you need the to add the owl.autoplay.js plugin. Then do the following

var owl = $('.owl-carousel');
owl.owlCarousel({
   items:1, //how many items you want to display
    loop:true,
    margin:10,
    autoplay:true,
    autoplayTimeout:10000,
    autoplayHoverPause:true
});

In SQL Server...

SELECT [name] AS [Column Name]
FROM syscolumns
WHERE id = (SELECT id FROM sysobjects WHERE type = 'V' AND [Name] = 'Your table name')

Type = 'V' for views Type = 'U' for tables

You can use this for check modify date of functions and stored procedures together ordered by date :

SELECT 'Stored procedure' as [Type] ,name, create_date, modify_date 
FROM sys.objects
WHERE type = 'P' 

UNION all

Select 'Function' as [Type],name, create_date, modify_date
FROM sys.objects
WHERE type = 'FN'
ORDER BY modify_date DESC

or :

SELECT type ,name, create_date, modify_date 
FROM sys.objects
WHERE type in('P','FN') 
ORDER BY modify_date DESC
-- this one shows type like : FN for function and P for stored procedure

Result will be like this :

Type                 |  name      | create_date              |  modify_date
'Stored procedure'   | 'firstSp'  | 2018-08-04 07:36:40.890  |  2019-09-05 05:18:53.157
'Stored procedure'   | 'secondSp' | 2017-10-15 19:39:27.950  |  2019-09-05 05:15:14.963
'Function'           | 'firstFn'  | 2019-09-05 05:08:53.707  |  2019-09-05 05:08:53.707

Copy content of BranchA into BranchB

git checkout BranchA
git pull origin BranchB
git push -u origin BranchA

Here is an example ...

select * from tablename where to_char(added_time, 'YYYY-MM-DD')  = to_char( now(), 'YYYY-MM-DD' )

added_time is a column name which I converted to char for match

You can call .prop("tagName"). Examples:

jQuery("<a>").prop("tagName"); //==> "A"
jQuery("<h1>").prop("tagName"); //==> "H1"
jQuery("<coolTagName999>").prop("tagName"); //==> "COOLTAGNAME999"

If writing out .prop("tagName") is tedious, you can create a custom function like so:

jQuery.fn.tagName = function() {
  return this.prop("tagName");
};

Examples:

jQuery("<a>").tagName(); //==> "A"
jQuery("<h1>").tagName(); //==> "H1"
jQuery("<coolTagName999>").tagName(); //==> "COOLTAGNAME999"

Note that tag names are, by convention, returned CAPITALIZED. If you want the returned tag name to be all lowercase, you can edit the custom function like so:

jQuery.fn.tagNameLowerCase = function() {
  return this.prop("tagName").toLowerCase();
};

Examples:

jQuery("<a>").tagNameLowerCase(); //==> "a"
jQuery("<h1>").tagNameLowerCase(); //==> "h1"
jQuery("<coolTagName999>").tagNameLowerCase(); //==> "cooltagname999"

The only way to add any book marks in MobileSafari (including ones on the home screen) is with the builtin UI, and that Apples does not provide anyway to do this from scripts within a page. In fact, I am pretty sure there is no mechanism for doing this on the desktop version of Safari either.

Assuming that you have and trust (to be authoritative) the list of escape characters Java regex uses (would be nice if these characters were exposed in some Pattern class member) you can use the following method to escape the character if it is indeed necessary:

private static final char[] escapeChars = { '<', '(', '[', '{', '\\', '^', '-', '=', '$', '!', '|', ']', '}', ')', '?', '*', '+', '.', '>' };

private static String regexEscape(char character) {
    for (char escapeChar : escapeChars) {
        if (character == escapeChar) {
            return "\\" + character;
        }
    }
    return String.valueOf(character);
}

Since an abstract class can have variables of all access modifiers, they have to be initialized to default values, so constructor is necessary. As you instantiate the child class, a constructor of an abstract class is invoked and variables are initialized.

On the contrary, an interface does contain only constant variables means they are already initialized. So interface doesn't need a constructor.

I don't understand where the first "result with sample data" is coming from, but the problem in the console app is that you're using SelectMany to look at each item in each group.

I think you just want:

List<ResultLine> result = Lines
    .GroupBy(l => l.ProductCode)
    .Select(cl => new ResultLine
            {
                ProductName = cl.First().Name,
                Quantity = cl.Count().ToString(),
                Price = cl.Sum(c => c.Price).ToString(),
            }).ToList();

The use of First() here to get the product name assumes that every product with the same product code has the same product name. As noted in comments, you could group by product name as well as product code, which will give the same results if the name is always the same for any given code, but apparently generates better SQL in EF.

I'd also suggest that you should change the Quantity and Price properties to be int and decimal types respectively - why use a string property for data which is clearly not textual?

I also wrote a C#/VB.Net "Export to Excel" library, which uses OpenXML and (more importantly) also uses OpenXmlWriter, so you won't run out of memory when writing large files.

Full source code, and a demo, can be downloaded here:

Export to Excel

It's dead easy to use. Just pass it the filename you want to write to, and a DataTable, DataSet or List<>.

CreateExcelFile.CreateExcelDocument(myDataSet, "MyFilename.xlsx");

And if you're calling it from an ASP.Net application, pass it the HttpResponse to write the file out to.

CreateExcelFile.CreateExcelDocument(myDataSet, "MyFilename.xlsx", Response);

I found the nice resource Standard C++ Containers. Probably this is what you all looking for.

VECTOR

Constructors

vector<T> v;              Make an empty vector.                                     O(1)
vector<T> v(n);           Make a vector with N elements.                            O(n)
vector<T> v(n, value);    Make a vector with N elements, initialized to value.      O(n)
vector<T> v(begin, end);  Make a vector and copy the elements from begin to end.    O(n)

Accessors

v[i]          Return (or set) the I'th element.                        O(1)
v.at(i)       Return (or set) the I'th element, with bounds checking.  O(1)
v.size()      Return current number of elements.                       O(1)
v.empty()     Return true if vector is empty.                          O(1)
v.begin()     Return random access iterator to start.                  O(1)
v.end()       Return random access iterator to end.                    O(1)
v.front()     Return the first element.                                O(1)
v.back()      Return the last element.                                 O(1)
v.capacity()  Return maximum number of elements.                       O(1)

Modifiers

v.push_back(value)         Add value to end.                                                O(1) (amortized)
v.insert(iterator, value)  Insert value at the position indexed by iterator.                O(n)
v.pop_back()               Remove value from end.                                           O(1)
v.assign(begin, end)       Clear the container and copy in the elements from begin to end.  O(n)
v.erase(iterator)          Erase value indexed by iterator.                                 O(n)
v.erase(begin, end)        Erase the elements from begin to end.                            O(n)

For other containers, refer to the page.

This will print the data in columns and comes to new line once last column is reached.

ResultSetMetaData resultSetMetaData = res.getMetaData();
int columnCount = resultSetMetaData.getColumnCount();
for(int i =1; i<=columnCount; i++){
                if(!(i==columnCount)){

                    System.out.print(res.getString(i)+"\t");
                }
                else{
                    System.out.println(res.getString(i));
                }

            }

If you try exec sp_rename and receieve a LockMatchID error then it might help to add a use [database] statement first:

I tried

 exec sp_rename '[database_name].[dbo].[table_name]', 'new_table_name';
 -- Invalid EXECUTE statement using object "Object", method "LockMatchID".

What I had to do to fix it was to rewrite it to:

use database_name
exec sp_rename '[dbo].[table_name]', 'new_table_name';

Since you actually want a different array which is arr where arr < 255, and 255 otherwise, this can be done simply:

result = np.minimum(arr, 255)

More generally, for a lower and/or upper bound:

result = np.clip(arr, 0, 255)

If you just want to access the values over 255, or something more complicated, @mtitan8's answer is more general, but np.clip and np.minimum (or np.maximum) are nicer and much faster for your case:

In [292]: timeit np.minimum(a, 255)
100000 loops, best of 3: 19.6 µs per loop

In [293]: %%timeit
   .....: c = np.copy(a)
   .....: c[a>255] = 255
   .....: 
10000 loops, best of 3: 86.6 µs per loop

If you want to do it in-place (i.e., modify arr instead of creating result) you can use the out parameter of np.minimum:

np.minimum(arr, 255, out=arr)

or

np.clip(arr, 0, 255, arr)

(the out= name is optional since the arguments in the same order as the function's definition.)

For in-place modification, the boolean indexing speeds up a lot (without having to make and then modify the copy separately), but is still not as fast as minimum:

In [328]: %%timeit
   .....: a = np.random.randint(0, 300, (100,100))
   .....: np.minimum(a, 255, a)
   .....: 
100000 loops, best of 3: 303 µs per loop

In [329]: %%timeit
   .....: a = np.random.randint(0, 300, (100,100))
   .....: a[a>255] = 255
   .....: 
100000 loops, best of 3: 356 µs per loop

For comparison, if you wanted to restrict your values with a minimum as well as a maximum, without clip you would have to do this twice, with something like

np.minimum(a, 255, a)
np.maximum(a, 0, a)

or,

a[a>255] = 255
a[a<0] = 0

If you can create your sql statement dynamically you can do following workaround:

String myArray[][] = { { "1-1", "1-2" }, { "2-1", "2-2" }, { "3-1", "3-2" } };

StringBuffer mySql = new StringBuffer("insert into MyTable (col1, col2) values (?, ?)");

for (int i = 0; i < myArray.length - 1; i++) {
    mySql.append(", (?, ?)");
}

myStatement = myConnection.prepareStatement(mySql.toString());

for (int i = 0; i < myArray.length; i++) {
    myStatement.setString(i, myArray[i][1]);
    myStatement.setString(i, myArray[i][2]);
}
myStatement.executeUpdate();

You probably want os.makedirs as it will create intermediate directories as well, if needed.

import os

#dir is not keyword
def makemydir(whatever):
  try:
    os.makedirs(whatever)
  except OSError:
    pass
  # let exception propagate if we just can't
  # cd into the specified directory
  os.chdir(whatever)

I believe the problem is that codecs.BOM_UTF8 is a byte string, not a Unicode string. I suspect the file handler is trying to guess what you really mean based on "I'm meant to be writing Unicode as UTF-8-encoded text, but you've given me a byte string!"

Try writing the Unicode string for the byte order mark (i.e. Unicode U+FEFF) directly, so that the file just encodes that as UTF-8:

import codecs

file = codecs.open("lol", "w", "utf-8")
file.write(u'\ufeff')
file.close()

(That seems to give the right answer - a file with bytes EF BB BF.)

EDIT: S. Lott's suggestion of using "utf-8-sig" as the encoding is a better one than explicitly writing the BOM yourself, but I'll leave this answer here as it explains what was going wrong before.

The error means that R could not find the variable mentioned in the error message.

The easiest way to reproduce the error is to type the name of a variable that doesn't exist. (If you've defined x already, use a different variable name.)

x
## Error: object 'x' not found

The more complex version of the error has the same cause: calling a function when x does not exist.

mean(x)
## Error in mean(x) : 
##   error in evaluating the argument 'x' in selecting a method for function 'mean': Error: object 'x' not found

Once the variable has been defined, the error will not occur.

x <- 1:5
x
## [1] 1 2 3 4 5     
mean(x)
## [1] 3

You can check to see if a variable exists using ls or exists.

ls()        # lists all the variables that have been defined
exists("x") # returns TRUE or FALSE, depending upon whether x has been defined.

Errors like this can occur when you are using non-standard evaluation. For example, when using subset, the error will occur if a column name is not present in the data frame to subset.

d <- data.frame(a = rnorm(5))
subset(d, b > 0)
## Error in eval(expr, envir, enclos) : object 'b' not found

The error can also occur if you use custom evaluation.

get("var", "package:stats") #returns the var function
get("var", "package:utils")
## Error in get("var", "package:utils") : object 'var' not found

In the second case, the var function cannot be found when R looks in the utils package's environment because utils is further down the search list than stats.

In more advanced use cases, you may wish to read:

• The Scope section of the CRAN manual Intro to R and demo(scoping)
• The Non-standard evaluation chapter of Advanced R

Use the hex code for a non-breaking space. Something like this:

    do{
    try value.write(toFile: path, atomically: true, encoding: String.Encoding.utf8)
}catch{
    }
    }

func readFromDocumentsFile(fileName:String) -> String {
    let documentsPath = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)[0] as NSString
    let path = documentsPath.appendingPathComponent(fileName)
    let checkValidation = FileManager.default
    var file:String

    if checkValidation.fileExists(atPath: path) {
        do{
       try file = NSString(contentsOfFile: path, encoding: String.Encoding.utf8.rawValue) as String
        }catch{
            file = ""
        }
        } else {
        file = ""
    }

    return file
}

To revert the last applied migration you should (package manager console commands):

1. Revert migration from database: PM> Update-Database <prior-migration-name>
2. Remove migration file from project (or it will be reapplied again on next step)
3. Update model snapshot: PM> Remove-Migration

UPD: The second step seems to be not required in latest versions of Visual Studio (2017).

[Context] In a virtual machine of WinXP.

Hope it helps!!

strip() returns the string with leading and trailing whitespaces(by default) removed.

So it would turn " Hello World " to "Hello World", but it won't remove the \n character as it is present in between the string.

Try replace().

str = "Hello \n World"
str2 = str.replace('\n', '')
print str2

One line version:

String text = ((Spinner)findViewById(R.id.spinner)).getSelectedItem().toString();

UPDATE: You can remove casting if you use SDK 26 (or newer) to compile your project.

String text = findViewById(R.id.spinner).getSelectedItem().toString();

Also, if you have commited sensitive data (e.g. a file containing passwords), you should completely delete it from the history of the repository. Here's a guide explaining how to do that: http://help.github.com/remove-sensitive-data/

Use the modern version of the Fisher–Yates shuffle algorithm:

/**
 * Shuffles array in place.
 * @param {Array} a items An array containing the items.
 */
function shuffle(a) {
    var j, x, i;
    for (i = a.length - 1; i > 0; i--) {
        j = Math.floor(Math.random() * (i + 1));
        x = a[i];
        a[i] = a[j];
        a[j] = x;
    }
    return a;
}

ES2015 (ES6) version

/**
 * Shuffles array in place. ES6 version
 * @param {Array} a items An array containing the items.
 */
function shuffle(a) {
    for (let i = a.length - 1; i > 0; i--) {
        const j = Math.floor(Math.random() * (i + 1));
        [a[i], a[j]] = [a[j], a[i]];
    }
    return a;
}

Note however, that swapping variables with destructuring assignment causes significant performance loss, as of October 2017.

Use

var myArray = ['1','2','3','4','5','6','7','8','9'];
shuffle(myArray);

Implementing prototype

Using Object.defineProperty (method taken from this SO answer) we can also implement this function as a prototype method for arrays, without having it show up in loops such as for (i in arr). The following will allow you to call arr.shuffle() to shuffle the array arr:

Object.defineProperty(Array.prototype, 'shuffle', {
    value: function() {
        for (let i = this.length - 1; i > 0; i--) {
            const j = Math.floor(Math.random() * (i + 1));
            [this[i], this[j]] = [this[j], this[i]];
        }
        return this;
    }
});

A more pythonic way would be:

try:
    os.remove(filename)
except OSError:
    pass

Although this takes even more lines and looks very ugly, it avoids the unnecessary call to os.path.exists() and follows the python convention of overusing exceptions.

It may be worthwhile to write a function to do this for you:

import os, errno

def silentremove(filename):
    try:
        os.remove(filename)
    except OSError as e: # this would be "except OSError, e:" before Python 2.6
        if e.errno != errno.ENOENT: # errno.ENOENT = no such file or directory
            raise # re-raise exception if a different error occurred

It looks like you're writing PHP, in which case you want:

<?
$arr=array('us'=>'United', 'ca'=>'canada');
$key='ca';
echo $arr[$key];
?>

Notice that the ('us'=>'United', 'ca'=>'canada') needs to be a parameter to the array function in PHP.

Most programming languages that support associative arrays or dictionaries use arr['key'] to retrieve the item specified by 'key'

For instance:

Ruby

ruby-1.9.1-p378 > h = {'us' => 'USA', 'ca' => 'Canada' }
 => {"us"=>"USA", "ca"=>"Canada"} 
ruby-1.9.1-p378 > h['ca']
 => "Canada" 

Python

>>> h = {'us':'USA', 'ca':'Canada'}
>>> h['ca']
'Canada'

C#

class P
{
    static void Main()
    {
        var d = new System.Collections.Generic.Dictionary<string, string> { {"us", "USA"}, {"ca", "Canada"}};
        System.Console.WriteLine(d["ca"]);
    }
}

Lua

t = {us='USA', ca='Canada'}
print(t['ca'])
print(t.ca) -- Lua's a little different with tables

SLaks hit the nail on the head but you might want to look over the changes for inputs in CSS3 in general. Rounded corners and box-shadow are both new features in CSS3 and will let you do exactly what you're looking for. One of my personal favorite links for CSS3/HTML5 is http://diveintohtml5.ep.io/ .

It's like porn, you know it when you see it. The only possible definition of a scripting language is:

A language which is described as a scripting language.

A bit circular, isn't it? (By the way, I'm not joking).

Basically, there is nothing that makes a language a scripting language except that it is called such, especially by its creators. The major set of modern scripting languages is PHP, Perl, JavaScript, Python, Ruby and Lua. Tcl is the first major modern scripting language (it wasn't the first scripting language though, I forget what it is, but I was surprised to learn that it predated Tcl).

I describe features of major scripting languages in my paper:

 A Practical Solution for Scripting Language Compilers
 Paul Biggar, Edsko de Vries and David Gregg
 SAC '09: ACM Symposium on Applied Computing (2009), (March 2009)

Most are dynamically typed and interpreted, and most have no defined semantics outside of their reference implementation. However, even if their major implementation becomes compiled or JITed, that doesn't change the "nature" of the language.

They only remaining question is how can you tell if a new language is a scripting language. Well, if it's called a scripting language, it is one. So Factor is a scripting language (or at least was when that was written), but, say, Java is not.

$('body').heartbeat(); // Simple
$('body').heartbeat({url:'@Url.Action("Home", "heartbeat")'}); // different url
$('body').heartbeat({every:6*60*1000}); // different timeout

If you want to add a flag to every link, e.g. -fsanitize=address then I would not recommend using CMAKE_*_LINKER_FLAGS. Even with them all set it still doesn't use the flag when linking a framework on OSX, and maybe in other situations. Instead use link_libraries():

add_compile_options("-fsanitize=address")
link_libraries("-fsanitize=address")

This works for everything.

I found that as of May, 2012, if you set the frame size so that the minimum pixel area (width • height) is above a certain threshold, it bumps the quality up from 360p to 480p, if you're video is at least 640 x 360.

I've discovered that setting a frame size to 780 x 480 for the embed frame triggers the 480p quality, without distorting the video (scaling up). 640 x 585 also works in this manner. I also used the &hd=1 parameter, but I doubt this has much control if your video is not uploaded in HD (720p or higher).

For instance:

<iframe width="780" height="480" src="http://www.youtube.com/embed/[VIDEO-ID]?rel=0&fs=1&showinfo=0&autohide=1&hd=1"></iframe>

Of course, the drawback is that by setting these static frame dimensions, you will most likely get black bars on the sides or above and below, depending on what you prefer.

If you didn't care about the controls being cut-off, you could go on to use CSS and overflow: hidden to crop the black bars out of the frame, providing you know the exact dimensions of the video.

Hope this helps, and hope the Embed method soon gets discrete quality parameters again one day!

First a link to some documentation of fork()

http://pubs.opengroup.org/onlinepubs/009695399/functions/fork.html

The pid is provided by the kernel. Every time the kernel create a new process it will increase the internal pid counter and assign the new process this new unique pid and also make sure there are no duplicates. Once the pid reaches some high number it will wrap and start over again.

So you never know what pid you will get from fork(), only that the parent will keep it's unique pid and that fork will make sure that the child process will have a new unique pid. This is stated in the documentation provided above.

If you continue reading the documentation you will see that fork() return 0 for the child process and the new unique pid of the child will be returned to the parent. If the child want to know it's own new pid you will have to query for it using getpid().

pid_t pid = fork()
if(pid == 0) {
    printf("this is a child: my new unique pid is %d\n", getpid());
} else {
    printf("this is the parent: my pid is %d and I have a child with pid %d \n", getpid(), pid);
}

and below is some inline comments on your code

#include <stdio.h>
#include <sys/types.h>
#include <unistd.h>

int main() {
    pid_t pid1, pid2, pid3;
    pid1=0, pid2=0, pid3=0;
    pid1= fork(); /* A */
    if(pid1 == 0){
        /* This is child A */
        pid2=fork(); /* B */
        pid3=fork(); /* C */
    } else {
        /* This is parent A */
        /* Child B and C will never reach this code */
        pid3=fork(); /* D */
        if(pid3==0) {
            /* This is child D fork'ed from parent A */
            pid2=fork(); /* E */
        }
        if((pid1 == 0)&&(pid2 == 0)) {
            /* pid1 will never be 0 here so this is dead code */
            printf("Level 1\n");
        }
        if(pid1 !=0) {
            /* This is always true for both parent and child E */
            printf("Level 2\n");
        }
        if(pid2 !=0) {
           /* This is parent E (same as parent A) */
           printf("Level 3\n");
        }
        if(pid3 !=0) {
           /* This is parent D (same as parent A) */
           printf("Level 4\n");
        }
    }
    return 0;
}

I don't know if there is a better way, but the following describes how I did it with a counter and background worker thread.

private object _lock = new object();
private int _runningThreads = 0;

private int Counter{
    get{
        lock(_lock)
            return _runningThreads;
    }
    set{
        lock(_lock)
            _runningThreads = value;
    }
}

Now whenever you create a worker thread, increment the counter:

var t = new BackgroundWorker();
// Add RunWorkerCompleted handler

// Start thread
Counter++;

In work completed, decrement the counter:

private void RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
{
    Counter--;
}

Now you can check for the counter anytime to see if any thread is running:

if(Couonter>0){
    // Some thread is yet to finish.
}

Absolutely Asset Catalog is you answer, it removes the need to follow naming conventions when you are adding or updating your app icons.

Below are the steps to Migrating an App Icon Set or Launch Image Set From Apple:

1- In the project navigator, select your target.

2- Select the General pane, and scroll to the App Icons section.

3- Specify an image in the App Icon table by clicking the folder icon on the right side of the image row and selecting the image file in the dialog that appears.

4-Migrate the images in the App Icon table to an asset catalog by clicking the Use Asset Catalog button, selecting an asset catalog from the popup menu, and clicking the Migrate button.

Alternatively, you can create an empty app icon set by choosing Editor > New App Icon, and add images to the set by dragging them from the Finder or by choosing Editor > Import.

If you mean "how can I get a reference to all markers on a given map" - then I think the answer is "Sorry, you have to do it yourself". I don't think there is any handy "maps.getMarkers()" type function: you have to keep your own references as the points are created:

var allMarkers = [];
....
// Create some markers
for(var i = 0; i < 10; i++) {
    var marker = new google.maps.Marker({...});
    allMarkers.push(marker);
}
...

Then you can loop over the allMarkers array to and do whatever you need to do.

Change the button to

<button id="search">Search</button>

and add the following script

var url = '@Url.Action("DisplaySearchResults", "Search")';
$('#search').click(function() {
  var keyWord = $('#Keyword').val();
  $('#searchResults').load(url, { searchText: keyWord });
})

and modify the controller method to accept the search text

public ActionResult DisplaySearchResults(string searchText)
{
  var model = // build list based on parameter searchText
   return PartialView("SearchResults", model);
}

The jQuery .load method calls your controller method, passing the value of the search text and updates the contents of the <div> with the partial view.

Side note: The use of a <form> tag and @Html.ValidationSummary() and @Html.ValidationMessageFor() are probably not necessary here. Your never returning the Index view so ValidationSummary makes no sense and I assume you want a null search text to return all results, and in any case you do not have any validation attributes for property Keyword so there is nothing to validate.

Edit

Based on OP's comments that SearchCriterionModel will contain multiple properties with validation attributes, then the approach would be to include a submit button and handle the forms .submit() event

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

var url = '@Url.Action("DisplaySearchResults", "Search")';
$('form').submit(function() {
  if (!$(this).valid()) { 
    return false; // prevent the ajax call if validation errors
  }
  var form = $(this).serialize();
  $('#searchResults').load(url, form);
  return false; // prevent the default submit action
})

and the controller method would be

public ActionResult DisplaySearchResults(SearchCriterionModel criteria)
{
  var model = // build list based on the properties of criteria
  return PartialView("SearchResults", model);
}

I also met the same problem and I was able to get it through. So let me explain the steps I applied. I shall explain it according to your scenario.

According to my method we need to use 'Path' class and 'Assembly' class in order to get the relative path.

So first Import System.IO and System.Reflection in using statements.

Then type the below given code line.

        var outPutDirectory = Path.GetDirectoryName(Assembly.GetExecutingAssembly(). CodeBase);

Actually above given line stores the path of the output directory of your project.(Here 'output' directory refers to the Debug folder of your project).

Now copy your FolderIcon directory in to the Debug folder. Then type the below given Line.

var iconPath = Path.Combine(outPutDirectory, "FolderIcon\\Folder.ico");

Now this 'iconPath ' variable contains the entire path of your Folder.ico. All you have to do is store it in a string variable. Use the line of code below for that.

string icon_path = new Uri(iconPath ).LocalPath;

Now you can use this icon_path string variable as your relative path to the icon.

Thanks.

Another cause could be a parent container that contains the CSS animation property. That's what it was for me.

/* you  can match the exact string with table value*/

if(md5("string to match") == $res["hashstring"])
 echo "login correct";

Actually, on 32-bit computers a word is 32-bit, but the DWORD type is a leftover from the good old days of 16-bit.

In order to make it easier to port programs to the newer system, Microsoft has decided all the old types will not change size.

You can find the official list here: http://msdn.microsoft.com/en-us/library/aa383751(VS.85).aspx

All the platform-dependent types that changed with the transition from 32-bit to 64-bit end with _PTR (DWORD_PTR will be 32-bit on 32-bit Windows and 64-bit on 64-bit Windows).

Often it is easier to parse without VBA, when you don't want to enable macros. This can be done with the replace function. Enter your start and end nodes into cells B1 and C1.

Cell A1: {your XML here}
Cell B1: <X>
Cell C1: </X>
Cell D1: =REPLACE(A1,1,FIND(A2,A1)+LEN(A2)-1,"")
Cell E1: =REPLACE(A4,FIND(A3,A4),LEN(A4)-FIND(A3,A4)+1,"")

And the result line E1 will have your parsed value:

Cell A1: {your XML here}
Cell B1: <X>
Cell C1: </X>
Cell D1: 24.365<X><Y>78.68</Y></PointN>
Cell E1: 24.365
