Added shortcut Ctrl+Shift+X C to Keybindings (Window -> Preferences -> filter for Keys) when 'Editing Java Source' for 'Remove Active Session'.

You need to make the x-factor into an ordered factor with the ordering you want, e.g

x <- data.frame("variable"=letters[1:5], "value"=rnorm(5)) ## example data
x <- x[with(x,order(-value)), ] ## Sorting
x$variable <- ordered(x$variable, levels=levels(x$variable)[unclass(x$variable)])

ggplot(x, aes(x=variable,y=value)) + geom_bar() +
   scale_y_continuous("",formatter="percent") + coord_flip()

I don't know any better way to do the ordering operation. What I have there will only work if there are no duplicate levels for x$variable.

Here's a version without any position relative or absolute and without text-indent:

ul.dash {
    list-style: none;
    margin-left: 0;
    padding-left: 1em;
}
ul.dash > li:before {
    display: inline-block;
    content: "-";
    width: 1em;
    margin-left: -1em;
}

Enjoy ;)

So if you are simply using the unsophisticated API, like I often am (I use it in ipython a lot), then this is simply

yscale('log')
plot(...)

Hope this helps someone looking for a simple answer! :).

I can see a number of reasons:

Readability

string s = string.Format("Hey, {0} it is the {1}st day of {2}.  I feel {3}!", _name, _day, _month, _feeling);

vs:

string s = "Hey," + _name + " it is the " + _day + "st day of " + _month + ".  I feel " + feeling + "!";

Format Specifiers (and this includes the fact you can write custom formatters)

string s = string.Format("Invoice number: {0:0000}", _invoiceNum);

vs:

string s = "Invoice Number = " + ("0000" + _invoiceNum).Substr(..... /*can't even be bothered to type it*/)

String Template Persistence

What if I want to store string templates in the database? With string formatting:

_id         _translation
  1         Welcome {0} to {1}.  Today is {2}.
  2         You have {0} products in your basket.
  3         Thank-you for your order.  Your {0} will arrive in {1} working days.

vs:

_id         _translation
  1         Welcome
  2         to
  3         .  Today is
  4         . 
  5         You have
  6         products in your basket.
  7         Someone
  8         just shoot
  9         the developer.

Or alternatively, you could use this:

WHERE CHARINDEX(N'Apples', someColumn) = 0

Not sure which one performs better - you gotta test it! :-)

Marc

UPDATE: the performance seems to be pretty much on a par with the other solution (WHERE someColumn NOT LIKE '%Apples%') - so it's really just a question of your personal preference.

One more point to all the above correct answers, it depends on what sort of programming you are doing. Kernel developing in Windows for example -> The stack is severely limited and you might not be able to take page faults like in user mode.

In such environments, new, or C-like API calls are prefered and even required.

Of course, this is merely an exception to the rule.

Map has the following implementations:

1. HashMap Map m = new HashMap();

2. LinkedHashMap Map m = new LinkedHashMap();

3. Tree Map Map m = new TreeMap();

4. WeakHashMap Map m = new WeakHashMap();

Suppose you have created one method (this is just pseudocode).

public void HashMap getMap(){
   return map;
}

Suppose your project requirements change:

1. The method should return map contents - Need to return HashMap.
2. The method should return map key's in insertion order - Need to change return type HashMap to LinkedHashMap.
3. The method should return map key's in sorted order - Need to change return type LinkedHashMap to TreeMap.

If your method returns specific classes instead of something that implements the Map interface, you have to change the return type of getMap() method each time.

But if you use the polymorphism feature of Java, and instead of returning specific classes, use the interface Map, it improves code reusability and reduces the impact of requirement changes.

I would try to avoid inserting empty lists in the first place, but, would generally use:

d = {k: v for k,v in d.iteritems() if v} # re-bind to non-empty

If prior to 2.7:

d = dict( (k, v) for k,v in d.iteritems() if v )

or just:

empty_key_vals = list(k for k in k,v in d.iteritems() if v)
for k in empty_key_vals:
    del[k]

SELECT group, date, checks
  FROM table 
  WHERE checks > 0
  GROUP BY group HAVING date = max(date) 

should work.

var top = ($(".apps_intro_wrapper_inner").offset() || { "top": NaN }).top;   
if (!isNaN(top)) {
$("#app_scroler").click(function () {   
$('html, body').animate({
            scrollTop: top
        }, 100);
    });
}

if you want to scroll a little above or below from specific div that add value to the top like this.....like I add 800

var top = ($(".apps_intro_wrapper_inner").offset() || { "top": NaN }).top + 800;

@parag's code works great. But while loading some large images you may fail. You should use;

imageView.setImageBitmap(getScaledBitmap(picturePath, 800, 800));

instead of;

imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));

Here are my methods that you can use.

private Bitmap getScaledBitmap(String picturePath, int width, int height) {
    BitmapFactory.Options sizeOptions = new BitmapFactory.Options();
    sizeOptions.inJustDecodeBounds = true;
    BitmapFactory.decodeFile(picturePath, sizeOptions);

    int inSampleSize = calculateInSampleSize(sizeOptions, width, height);

    sizeOptions.inJustDecodeBounds = false;
    sizeOptions.inSampleSize = inSampleSize;

    return BitmapFactory.decodeFile(picturePath, sizeOptions);
}

private int calculateInSampleSize(BitmapFactory.Options options, int reqWidth, int reqHeight) {
    // Raw height and width of image
    final int height = options.outHeight;
    final int width = options.outWidth;
    int inSampleSize = 1;

    if (height > reqHeight || width > reqWidth) {

        // Calculate ratios of height and width to requested height and
        // width
        final int heightRatio = Math.round((float) height / (float) reqHeight);
        final int widthRatio = Math.round((float) width / (float) reqWidth);

        // Choose the smallest ratio as inSampleSize value, this will
        // guarantee
        // a final image with both dimensions larger than or equal to the
        // requested height and width.
        inSampleSize = heightRatio < widthRatio ? heightRatio : widthRatio;
    }

    return inSampleSize;
}

I know that this topic is quite old, but this need is still alive. I read many documents, forum and script and build a new advanced one which supports compressed and uncompressed pdf :

Put these inside a .hta file and run it. Tested on W7, IE11. It's working. Also if you want me to explain what's going on, say so.

Programming the Mandelbrot is easy.
My quick-n-dirty code is below (not guaranteed to be bug-free, but a good outline).

Here's the outline: The Mandelbrot-set lies in the Complex-grid completely within a circle with radius 2.

So, start by scanning every point in that rectangular area. Each point represents a Complex number (x + yi). Iterate that complex number:

[new value] = [old-value]^2 + [original-value] while keeping track of two things:

1.) the number of iterations

2.) the distance of [new-value] from the origin.

If you reach the Maximum number of iterations, you're done. If the distance from the origin is greater than 2, you're done.

When done, color the original pixel depending on the number of iterations you've done. Then move on to the next pixel.

public void MBrot()
{
    float epsilon = 0.0001; // The step size across the X and Y axis
    float x;
    float y;
    int maxIterations = 10; // increasing this will give you a more detailed fractal
    int maxColors = 256; // Change as appropriate for your display.

    Complex Z;
    Complex C;
    int iterations;
    for(x=-2; x<=2; x+= epsilon)
    {
        for(y=-2; y<=2; y+= epsilon)
        {
            iterations = 0;
            C = new Complex(x, y);
            Z = new Complex(0,0);
            while(Complex.Abs(Z) < 2 && iterations < maxIterations)
            {
                Z = Z*Z + C;
                iterations++;
            }
            Screen.Plot(x,y, iterations % maxColors); //depending on the number of iterations, color a pixel.
        }
    }
}

Some details left out are:

1.) Learn exactly what the Square of a Complex number is and how to calculate it.

2.) Figure out how to translate the (-2,2) rectangular region to screen coordinates.

Building on Ravinders solution, this code stops the form being submitted. It might be wise to check the extension at the server-side too. So you don't get hackers uploading anything they want.

<script>
var valid = false;

function validate_fileupload(input_element)
{
    var el = document.getElementById("feedback");
    var fileName = input_element.value;
    var allowed_extensions = new Array("jpg","png","gif");
    var file_extension = fileName.split('.').pop(); 
    for(var i = 0; i < allowed_extensions.length; i++)
    {
        if(allowed_extensions[i]==file_extension)
        {
            valid = true; // valid file extension
            el.innerHTML = "";
            return;
        }
    }
    el.innerHTML="Invalid file";
    valid = false;
}

function valid_form()
{
    return valid;
}
</script>

<div id="feedback" style="color: red;"></div>

As long as adding clientConfig.getFeatures().put(JSONConfiguration.FEATURE_POJO_MAPPING, true); on client creation solved the issue for me:

ClientConfig clientConfig = new DefaultClientConfig();
clientConfig.getFeatures().put(JSONConfiguration.FEATURE_POJO_MAPPING, true);
Client client = Client.create(clientConfig);

I am doing it this way and its working.

$('#form').submit(function(){
    $.ajax({
      url: $('#form').attr('action'),
      type: 'POST',
      data : $('#form').serialize(),
      success: function(){
        console.log('form submitted.');
      }
    });
    return false;
});

You can use the required html attribute if you want:

@Html.TextBoxFor(m => m.ShortName, 
new { @class = "form-control", placeholder = "short name", required="required"})

or you can use the RequiredAttribute class in .Net. With jQuery the RequiredAttribute can Validate on the front end and server side. If you want to go the MVC route, I'd suggest reading Data annotations MVC3 Required attribute.

OR

You can get really advanced:

@{
  // if you aren't using UnobtrusiveValidation, don't pass anything to this constructor
  var attributes = new Dictionary<string, object>(
    Html.GetUnobtrusiveValidationAttributes(ViewData.TemplateInfo.HtmlFieldPrefix));

 attributes.Add("class", "form-control");
 attributes.Add("placeholder", "short name");

  if (ViewData.ModelMetadata.ContainerType
      .GetProperty(ViewData.ModelMetadata.PropertyName)
      .GetCustomAttributes(typeof(RequiredAttribute), true)
      .Select(a => a as RequiredAttribute)
      .Any(a => a != null))
  {
   attributes.Add("required", "required");
  }

  @Html.TextBoxFor(m => m.ShortName, attributes)

}

or if you need it for multiple editor templates:

public static class ViewPageExtensions
{
  public static IDictionary<string, object> GetAttributes(this WebViewPage instance)
  {
    // if you aren't using UnobtrusiveValidation, don't pass anything to this constructor
    var attributes = new Dictionary<string, object>(
      instance.Html.GetUnobtrusiveValidationAttributes(
         instance.ViewData.TemplateInfo.HtmlFieldPrefix));

    if (ViewData.ModelMetadata.ContainerType
      .GetProperty(ViewData.ModelMetadata.PropertyName)
      .GetCustomAttributes(typeof(RequiredAttribute), true)
      .Select(a => a as RequiredAttribute)
      .Any(a => a != null))
    {
      attributes.Add("required", "required");
    }
  }
}

then in your templates:

@{
  // if you aren't using UnobtrusiveValidation, don't pass anything to this constructor
  var attributes = this.GetAttributes();

  attributes.Add("class", "form-control");
  attributes.Add("placeholder", "short name");

  @Html.TextBoxFor(m => m.ShortName, attributes)

}

Update 1 (for Tomas who is unfamilar with ViewData).

What's the difference between ViewData and ViewBag?

Excerpt:

So basically it (ViewBag) replaces magic strings:

ViewData["Foo"]

with magic properties:

ViewBag.Foo

To answer your first question: yes it is feasible to develop an android application in pure python, in order to achieve this I suggest you use BeeWare, which is just a suite of python tools, that work together very well and they enable you to develop platform native applications in python.

checkout this video by the creator of BeeWare that perfectly explains and demonstrates it's application

How it works

Android's preferred language of implementation is Java - so if you want to write an Android application in Python, you need to have a way to run your Python code on a Java Virtual Machine. This is what VOC does. VOC is a transpiler - it takes Python source code, compiles it to CPython Bytecode, and then transpiles that bytecode into Java-compatible bytecode. The end result is that your Python source code files are compiled directly to a Java .class file, which can be packaged into an Android application.

VOC also allows you to access native Java objects as if they were Python objects, implement Java interfaces with Python classes, and subclass Java classes with Python classes. Using this, you can write an Android application directly against the native Android APIs.

Once you've written your native Android application, you can use Briefcase to package your Python code as an Android application.

Briefcase is a tool for converting a Python project into a standalone native application. You can package projects for:

• Mac
• Windows
• Linux
• iPhone/iPad
• Android
• AppleTV
• tvOS.

You can check This native Android Tic Tac Toe app written in Python, using the BeeWare suite. on GitHub

in addition to the BeeWare tools, you'll need to have a JDK and Android SDK installed to test run your application.

and to answer your second question: a good environment can be anything you are comfortable with be it a text editor and a command line, or an IDE, if you're looking for a good python IDE I would suggest you try Pycharm, it has a community edition which is free, and it has a similar environment as android studio, due to to the fact that were made by the same company.

I hope this has been helpful

If installed as an admin, use:-

uname - admin
pw - the passkey that was generated during installation

You can enable and disable column editing mode via the keyboard shortcut ALT-SHIFT-A.

Once enabled you can then use either the mouse to select a block of text, or the keyboard using SHIFT (like a normal keyboard select, except the selection will now be in a block).

If you've changed your default font for text editing, entering column editing mode will probably change your screen font to the default column editing font (which is probably different to your changed font. To change the font when in column editing mode, go to the menu and select Window -> Preferences, then in the tree on the left hand side, pick General -> Appearance -> Colors and Fonts, and then pick Basic -> Text Editor Block Selection Font on the right hand side tree. You can then select the font to be consistent with your "not in column editing mode" font.

If you had generate a SSH-key with passphrase and then you forget your passphrase for this SSH-key,there's no way to recover it, You'll need to generate a brand new SSH keypair or switch to HTTPS cloning so you can use your GitHub password instead.

BUT,there are exceptions

If you configured your SSH passphrase with the OS X Keychain, you may be able to recover it.

1. In Finder, search for the Keychain Access app.
2. In Keychain Access, search for SSH.
3. Double click on the entry for your SSH key to open a new dialog box.
4. Keychain access dialogIn the lower-left corner, select Show password.
5. You'll be prompted for your administrative password. Type it into the "Keychain Access" dialog box.
6. Your password will be revealed.

Refer to Github help - How do I recover my SSH key passphrase?

Given the context loader.getResourceAsStream("myPackage/myProp.properties") should be used.

Leading '/' doesn't work with ClassLoader.getResourceAsStream(String) method.

Alternatively you could use Class.getResourceAsStream(String) method, which uses '/' to determine if the path is absolute or relative to the class location.

Examples:

myClass.class.getResourceAsStream("myProp.properties")
myClass.class.getResourceAsStream("/myPackage/myProp.properties")

Unfortunately, this cannot be done efficiently (better than O(n)) in any of the Standard Library set containers.

This is odd, since it is very easy to add a randomized pick function to hash sets as well as binary sets. In a not to sparse hash set, you can try random entries, until you get a hit. For a binary tree, you can choose randomly between the left or right subtree, with a maximum of O(log2) steps. I've implemented a demo of the later below:

import random

class Node:
    def __init__(self, object):
        self.object = object
        self.value = hash(object)
        self.size = 1
        self.a = self.b = None

class RandomSet:
    def __init__(self):
        self.top = None

    def add(self, object):
        """ Add any hashable object to the set.
            Notice: In this simple implementation you shouldn't add two
                    identical items. """
        new = Node(object)
        if not self.top: self.top = new
        else: self._recursiveAdd(self.top, new)
    def _recursiveAdd(self, top, new):
        top.size += 1
        if new.value < top.value:
            if not top.a: top.a = new
            else: self._recursiveAdd(top.a, new)
        else:
            if not top.b: top.b = new
            else: self._recursiveAdd(top.b, new)

    def pickRandom(self):
        """ Pick a random item in O(log2) time.
            Does a maximum of O(log2) calls to random as well. """
        return self._recursivePickRandom(self.top)
    def _recursivePickRandom(self, top):
        r = random.randrange(top.size)
        if r == 0: return top.object
        elif top.a and r <= top.a.size: return self._recursivePickRandom(top.a)
        return self._recursivePickRandom(top.b)

if __name__ == '__main__':
    s = RandomSet()
    for i in [5,3,7,1,4,6,9,2,8,0]:
        s.add(i)

    dists = [0]*10
    for i in xrange(10000):
        dists[s.pickRandom()] += 1
    print dists

I got [995, 975, 971, 995, 1057, 1004, 966, 1052, 984, 1001] as output, so the distribution seams good.

I've struggled with the same problem for myself, and I haven't yet decided weather the performance gain of this more efficient pick is worth the overhead of using a python based collection. I could of course refine it and translate it to C, but that is too much work for me today :)

Unless you have native code (machine code compiled for a specific arcitechture) your code will run equally well in a 32-bit and 64-bit JVM.

Note, however, that due to the larger adresses (32-bit is 4 bytes, 64-bit is 8 bytes) a 64-bit JVM will require more memory than a 32-bit JVM for the same task.

Let's consider a system where each user is linked to one or more roles and each role is linked to one or more access privileges. This information can be cached for better API performance. But then, there may be changes in the user and role configurations (for e.g. new access may be granted or current access may be revoked) and these should be reflected in the cache.

We can use access and refresh tokens for such purpose. When an API is invoked with access token, the resource server checks the cache for access rights. IF there is any new access grants, it is not reflected immediately. Once the access token expires (say in 30 minutes) and the client uses the refresh token to generate a new access token, the cache can be updated with the updated user access right information from the DB.

In other words, we can move the expensive operations from every API call using access tokens to the event of access token generation using refresh token.

Similar to Linux:

• /boot

• /system

• /recovery

• /data

• /cache

• /misc

The first statement depends on the context in which it is declared.

If it is declared in the global context it will create an implied global variable called "foo" which will be a variable which points to the function. Thus the function call "foo()" can be made anywhere in your javascript program.

If the function is created in a closure it will create an implied local variable called "foo" which you can then use to invoke the function inside the closure with "foo()"

EDIT:

I should have also said that function statements (The first one) are parsed before function expressions (The other 2). This means that if you declare the function at the bottom of your script you will still be able to use it at the top. Function expressions only get evaluated as they are hit by the executing code.

END EDIT

Statements 2 & 3 are pretty much equivalent to each other. Again if used in the global context they will create global variables and if used within a closure will create local variables. However it is worth noting that statement 3 will ignore the function name, so esentially you could call the function anything. Therefore

var foo = function foo() { return 5; }

Is the same as

var foo = function fooYou() { return 5; }

Use DATESTR

>> datestr(40189)
ans =
12-Jan-0110

Unfortunately, Excel starts counting at 1-Jan-1900. Find out how to convert serial dates from Matlab to Excel by using DATENUM

>> datenum(2010,1,11)
ans =
      734149
>> datenum(2010,1,11)-40189
ans =
      693960
>> datestr(40189+693960)
ans =
11-Jan-2010

In other words, to convert any serial Excel date, call

datestr(excelSerialDate + 693960)

EDIT

To get the date in mm/dd/yyyy format, call datestr with the specified format

excelSerialDate = 40189;
datestr(excelSerialDate + 693960,'mm/dd/yyyy')
ans =
01/11/2010

Also, if you want to get rid of the leading zero for the month, you can use REGEXPREP to fix things

excelSerialDate = 40189;
regexprep(datestr(excelSerialDate + 693960,'mm/dd/yyyy'),'^0','')
ans =
1/11/2010

Here's a solution that mixes the code by Jared Rummler and AndroidMechanic.

Note: fb://facewebmodal/f?href= redirects to a weird facebook page that doesn't have the like and other important buttons, which is why I try fb://page/. It works fine with the current Facebook version (126.0.0.21.77, June 1st 2017). The catch might be useless, I left it just in case.

    final String FACEBOOK_PAGE_ID = "123456789";
    final String FACEBOOK_URL = "MyFacebookPage";

    if(appInstalledOrNot(context, "com.facebook.katana"))
    {
        try
        {
            return "fb://page/" + FACEBOOK_PAGE_ID;
            // previous version, maybe relevant for old android APIs ?
            // return "fb://facewebmodal/f?href=" + FACEBOOK_URL;
        }

}

Here's the appInstalledOrNot function which I took (and modified) from Aerrow's answer to this post

private static boolean appInstalledOrNot(Context context, String uri)
{
    PackageManager pm = context.getPackageManager();
    try
    {
        pm.getPackageInfo(uri, PackageManager.GET_ACTIVITIES);
        return true;
    }
    catch(PackageManager.NameNotFoundException e)
    {
    }

    return false;
}

How to get the Facebook ID of a page:

1. Go to your page
2. Right-click and View Page Source
3. Find in page: fb://page/?id=
4. Here you go!

You can use this regex recursion to match everythin between, even another {} (like a JSON text) :

\{([^()]|())*\}

You could print the backspace character '\b' as many times as necessary to delete the line before printing the updated progress bar.

Well you need tuple of 2 elements, so

data = [1,2,3,4,5,6]
for i,k in zip(data[0::2], data[1::2]):
    print str(i), '+', str(k), '=', str(i+k)

Where:

• data[0::2] means create subset collection of elements that (index % 2 == 0)
• zip(x,y) creates a tuple collection from x and y collections same index elements.

In my case the Graphics Tools Windows feature installation was hanging forever. I've installed the Optional Windows Feature manually and restarted the setup of VS 2015.

I've used the implementation above and just now I came to know that it doesn't work on iPad running iOS 13. I had to add these lines before present() call in order to make it work

//avoiding to crash on iPad
if let popoverController = activityViewController.popoverPresentationController {
     popoverController.sourceRect = CGRect(x: UIScreen.main.bounds.width / 2, y: UIScreen.main.bounds.height / 2, width: 0, height: 0)
     popoverController.sourceView = self.view
     popoverController.permittedArrowDirections = UIPopoverArrowDirection(rawValue: 0)
}

That's how it works for me

func shareData(_ dataToShare: [Any]){

        let activityViewController = UIActivityViewController(activityItems: dataToShare, applicationActivities: nil)

        //exclude some activity types from the list (optional)
        //activityViewController.excludedActivityTypes = [
            //UIActivity.ActivityType.postToFacebook
        //]

        //avoiding to crash on iPad
        if let popoverController = activityViewController.popoverPresentationController {
            popoverController.sourceRect = CGRect(x: UIScreen.main.bounds.width / 2, y: UIScreen.main.bounds.height / 2, width: 0, height: 0)
            popoverController.sourceView = self.view
            popoverController.permittedArrowDirections = UIPopoverArrowDirection(rawValue: 0)
        }

        self.present(activityViewController, animated: true, completion: nil)
    }

Have a look at GROUP_CONCAT if your MySQL version (4.1) supports it. See the documentation for more details.

It would look something like:

  SELECT GROUP_CONCAT(hobbies SEPARATOR ', ') 
  FROM peoples_hobbies 
  WHERE person_id = 5 
  GROUP BY 'all';

public class MyThread {

    public static void main(String[] args) {
        // TODO Auto-generated method stub

        Threado o =new Threado();
        o.start();

        Threade e=new Threade();
        e.start();    
    }    
}


class Threade extends Thread{

    public void run(){

        for(int i=2;i<10;i=i+2)
            System.out.println("evens "+i);         
    }       
}


class Threado extends Thread{

    public void run(){

        for(int i=1;i<10;i=i+2)
            System.out.println("odds "+i);          
    }       
}

OUTPUT :-

odds 1 odds 3 odds 5 odds 7 odds 9 evens 2 evens 4 evens 6 evens 8

<div class="row">
  <div class="col-md-6">
     <img src="/assets/images/ebook2.png" alt="" class="img-fluid">
  </div>
  <div class="col-md-6 my-auto">
     <h3>Heading</h3>
     <p>Some text.</p>
   </div>
</div>

This line is where the magic happens <div class="col-md-6 my-auto">, the my-auto will center the content of the column. This works great with situations like the code sample above where you might have a variable sized image and need to have the text in the column to the right line up with it.

The below code useful to display in the map insertion order.

<ul>
    <li *ngFor="let recipient of map | keyvalue: asIsOrder">
        {{recipient.key}} --> {{recipient.value}}
    </li>
</ul>

.ts file add the below code.

asIsOrder(a, b) {
    return 1;
}

.md is markdown. README.md is used to generate the html summary you see at the bottom of projects. Github has their own flavor of Markdown.

Order of Preference: If you have two files named README and README.md, the file named README.md is preferred, and it will be used to generate github's html summary.

FWIW, Stack Overflow uses local Markdown modifications as well (also see Stack Overflow's C# Markdown Processor)

Usually the msb file not found problems are the result of an environment setting problem, but in your case I'm a little suspicious of the installation (I've never used the apt-get + configure method).

To check the sanity of the installation:

• ORACLE_HOME should be set to a directory path one level above the bin directory where sqlplus executable is found.
• There should some .msb files under $ORACLE_HOME/sqlplus/mesg
• There should be hundreds (not sure of the number with XE) of .msb files under $ORACLE_HOME (try find $ORACLE_HOME -name "*.msb" -print to show them)
• Your PATH should include $ORACLE_HOME/bin.
• All files under ORACLE_HOME should be owned by user:oracle group:dba.

wget

wget is a linux command, not a PHP command, so to run this you woud need to use exec, which is a PHP command for executing shell commands.

exec("wget --http-user=[user] --http-password=[pass] http://www.example.com/file.xml");

This can be useful if you are downloading a large file - and would like to monitor the progress, however when working with pages in which you are just interested in the content, there are simple functions for doing just that.

The exec function is enabled by default, but may be disabled in some situations. The configuration options for this reside in your php.ini, to enable, remove exec from the disabled_functions config string.

alternative

Using file_get_contents we can retrieve the contents of the specified URL/URI. When you just need to read the file into a variable, this would be the perfect function to use as a replacement for curl - follow the URI syntax when building your URL.

// standard url
$content = file_get_contents("http://www.example.com/file.xml");

// or with basic auth
$content = file_get_contents("http://user:[email protected]/file.xml");

As noted by Sean the Bean - you may also need to change allow_url_fopen to true in your php.ini to allow the use of a URL in this method, however, this should be true by default.

If you want to then store that file locally, there is a function file_put_contents to write that into a file, combined with the previous, this could emulate a file download:

file_put_contents("local_file.xml", $content);

Following are the ways

1. From the code (the way you have mentioned) ->

   displayBox.Text += sent + "\r\n";
   

   or

   displayBox.Text += sent + Environment.NewLine;
   

2. From the UI
   a) WPF

   Set TextWrapping="Wrap" and AcceptsReturn="True"   
   

   Press Enter key to the textbox and new line will be created

   b) Winform text box

   Set TextBox.MultiLine and TextBox.AcceptsReturn to true
   

You cant have multiple ng-view. Below is my use case where I solved my requirement. I wanted to have tabbed behavior in my model dialog. I was facing issue as click on tabs having hyperlink which will invoke router links. I solved this using button and css for tabs. When user clicks on tab, it actually will not call any hyperlink which will always invoke the ng-router. When user click on tab it will call a method, where I dynamcilly load html. Below is the function on click of tab

self.submit = function(form) {
                $templateRequest('resources/items/employee/test_template.html').then(function(template){
                var compiledeHTML = $compile(template)($scope);
                $("#d").replaceWith(compiledeHTML);
});

User $templateRequest. In test_template.html page add your html content. This html content will be bind to your controller.

Another alternative, even though the OP did not ask for it:

There exist usb-to-serial adapters. Depending on the type of adapter, you may also need a nullmodem cable, too.

They are extremely easy to use under linux, work under windows, too, if you have got working drivers installed.

That way you can work directly with the sensors, and you do not have to try and emulate data. That way you are maybe even save from building an anemic system. (Due to your emulated data inputs not covering all cases, leading you to a brittle system.)

Its often better to work with the real stuff.

The following worked for me:

html { height: 100vh; }

body {
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  width: 100vw;
}

/* this is the container you want to take the visible viewport  */
/* make sure this is top-level in body */
#your-app-container {
  height: 100%;
}

The body will take the visible viewport height and #your-app-container with height: 100% will make that container take the visible viewport height.

brew rmtree doesn't work at all. From the links on that issue I found rmrec which actually does work. God knows why brew doesn't have this as a native command.

brew tap ggpeti/rmrec
brew rmrec pkgname

Do you mean the class view window (View->Class View, or Ctrl+W,C)?

You also have the intellisence popup-window

The jQuery you're using is manipulates the DOM, not the CSS itself. Try changing the word span in your CSS to .mySpan, then apply that class to one or more DOM elements in your HTML like so:

...
<span class="mySpan">...</span>
...

Then, change your jQuery as follows:

$(".mySpan").css({ display : inline });

This should work much better.

Good luck!

As of XCode 7 this has become much easier.

Apple has documented the process on their site: https://developer.apple.com/library/ios/recipes/xcode_help-project_editor/RenamingaProject/RenamingaProject.html

Update: XCode 8 link: http://help.apple.com/xcode/mac/8.0/#/dev3db3afe4f

#if defined(CONDITION1) || defined(CONDITION2)

should work. :)

#ifdef is a bit less typing, but doesn't work well with more complex conditions

Depending on the language you're using it's going to be something simple like

CInt(CDate("1970-1-1") - CDate(Today()))

Ironically enough, yesterday was day 40,000 if you use 1/1/1900 as "day zero" like many computer systems use.

EditorFor works with metadata, so if you want to add html attributes you could always do it. Another option is to simply write a custom template and use TextBoxFor:

<%= Html.TextBoxFor(model => model.Control.PeriodType, 
    new { disabled = "disabled", @readonly = "readonly" }) %>    

Wouldn't it be more pythonic to use slicing?

For example, to pad a string with spaces on the right until it's 10 characters long:

>>> x = "string"    
>>> (x + " " * 10)[:10]   
'string    '

To pad it with spaces on the left until it's 15 characters long:

>>> (" " * 15 + x)[-15:]
'         string'

It requires knowing how long you want to pad to, of course, but it doesn't require measuring the length of the string you're starting with.

Usage

It's all about performance and development speed. Of course, if you are a good programmer and design something that is really tailored to your needs, you might achieve better performance than if you had used a Javascript framework. But do you have the time to do it all by yourself?

My personal opinion is that Javascript is incredibly useful and overused, but that if you really need it, a framework is the way to go.

Now comes the choice of the framework. For what benchmarks are worth, you can find one at http://ejohn.org/files/142/ . It also depends on which plugins are available and what you intend to do with them. I started using jQuery because it seemed to be maintained and well featured, even though it wasn't the fastest at that moment. I do not regret it but I didn't test anything else since then.

Or you can use std::advance

vector<int>::iterator i = L.begin();
advance(i, 2);

Gson gson = new GsonBuilder().setDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSZ").create();

Above format seems better to me as it has precision up to millis.

Arrays

• Set, Check element at a particular index: O(1)
• Searching: O(n) if array is unsorted and O(log n) if array is sorted and something like a binary search is used,
• As pointed out by Aivean, there is no Delete operation available on Arrays. We can symbolically delete an element by setting it to some specific value, e.g. -1, 0, etc. depending on our requirements
• Similarly, Insert for arrays is basically Set as mentioned in the beginning

ArrayList:

• Add: Amortized O(1)
• Remove: O(n)
• Contains: O(n)
• Size: O(1)

Linked List:

• Inserting: O(1), if done at the head, O(n) if anywhere else since we have to reach that position by traveseing the linkedlist linearly.
• Deleting: O(1), if done at the head, O(n) if anywhere else since we have to reach that position by traveseing the linkedlist linearly.
• Searching: O(n)

Doubly-Linked List:

• Inserting: O(1), if done at the head or tail, O(n) if anywhere else since we have to reach that position by traveseing the linkedlist linearly.
• Deleting: O(1), if done at the head or tail, O(n) if anywhere else since we have to reach that position by traveseing the linkedlist linearly.
• Searching: O(n)

Stack:

• Push: O(1)
• Pop: O(1)
• Top: O(1)
• Search (Something like lookup, as a special operation): O(n) (I guess so)

Queue/Deque/Circular Queue:

• Insert: O(1)
• Remove: O(1)
• Size: O(1)

Binary Search Tree:

• Insert, delete and search: Average case: O(log n), Worst Case: O(n)

Red-Black Tree:

• Insert, delete and search: Average case: O(log n), Worst Case: O(log n)

Heap/PriorityQueue (min/max):

• Find Min/Find Max: O(1)
• Insert: O(log n)
• Delete Min/Delete Max: O(log n)
• Extract Min/Extract Max: O(log n)
• Lookup, Delete (if at all provided): O(n), we will have to scan all the elements as they are not ordered like BST

HashMap/Hashtable/HashSet:

• Insert/Delete: O(1) amortized
• Re-size/hash: O(n)
• Contains: O(1)

ref():

Perl provides the ref() function so that you can check the reference type before dereferencing a reference...

By using the ref() function you can protect program code that dereferences variables from producing errors when the wrong type of reference is used...

SELECT * 
FROM (SELECT * FROM can
    UNION
    SELECT * FROM employee) as e
WHERE e.id = 1;

Try this:

@echo off &setlocal
setlocal enabledelayedexpansion

set "search=%1"
set "replace=%2"
set "textfile=Input.txt"
set "newfile=Output.txt"
(for /f "delims=" %%i in (%textfile%) do (
    set "line=%%i"
    set "line=!line:%search%=%replace%!"
    echo(!line!
))>"%newfile%"
del %textfile%
rename %newfile%  %textfile%
endlocal

I don't know how was the plugin the time the question was asked (2009), but I faced the same problem today and solved it this way:

1. Give your select tag a name attribute. For example in this case

   <select name="myselect">

2. Instead of working with the attribute value="default" in the tag option, disable the default option as suggested by Jeremy Visser or set value=""

   <option disabled="disabled">Choose...</option>

   or

   <option value="">Choose...</option>

3. Set the plugin validation rule

   $( "#YOUR_FORM_ID" ).validate({ rules: { myselect: { required: true } } });

   or

   <select name="myselect" class="required">

Obs: redsquare's solution works only if you have just one select in your form. If you want his solution to work with more than one select add a name attribute to your select.

Hope it helps! :)

You can also give weight separately like this ,

LayoutParams lp1 = new LayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.MATCH_PARENT);

 lp1.weight=1;

Try something like this:

public class test 
{  

    public static void main(String a[])
    {  
        long tmp = 1346524199000;  

        Date d = new Date(tmp);  
        System.out.println(d);  
    }  
} 

There are already many good answers, but if your entire file is on a single line and you still want to process "rows" (as opposed to fixed-size blocks), these answers will not help you.

99% of the time, it is possible to process files line by line. Then, as suggested in this answer, you can to use the file object itself as lazy generator:

with open('big.csv') as f:
    for line in f:
        process(line)

However, I once ran into a very very big (almost) single line file, where the row separator was in fact not '\n' but '|'.

• Reading line by line was not an option, but I still needed to process it row by row.
• Converting'|' to '\n' before processing was also out of the question, because some of the fields of this csv contained '\n' (free text user input).
• Using the csv library was also ruled out because the fact that, at least in early versions of the lib, it is hardcoded to read the input line by line.

For these kind of situations, I created the following snippet:

def rows(f, chunksize=1024, sep='|'):
    """
    Read a file where the row separator is '|' lazily.

    Usage:

    >>> with open('big.csv') as f:
    >>>     for r in rows(f):
    >>>         process(row)
    """
    curr_row = ''
    while True:
        chunk = f.read(chunksize)
        if chunk == '': # End of file
            yield curr_row
            break
        while True:
            i = chunk.find(sep)
            if i == -1:
                break
            yield curr_row + chunk[:i]
            curr_row = ''
            chunk = chunk[i+1:]
        curr_row += chunk

I was able to use it successfully to solve my problem. It has been extensively tested, with various chunk sizes.

You'll have to find the index of the person in your persons array, then use the array's splice method:

$scope.persons.splice( $scope.persons.indexOf(person), 1 );

This might help you

In most cases, the system does not relaunch apps after they are force quit by the user. One exception is location apps, which in iOS 8 and later are relaunched after being force quit by the user. In other cases, though, the user must launch the app explicitly or reboot the device before the app can be launched automatically into the background by the system. When password protection is enabled on the device, the system does not launch an app in the background before the user first unlocks the device.

By default, Valgrind writes its output to stderr. So you need to do something like:

valgrind a.out > log.txt 2>&1

Alternatively, you can tell Valgrind to write somewhere else; see http://valgrind.org/docs/manual/manual-core.html#manual-core.comment (but I've never tried this).

var http = require('http');
var url = process.argv[2];

http.get(url, function(response) {
  var finalData = "";

  response.on("data", function (data) {
    finalData += data.toString();
  });

  response.on("end", function() {
    console.log(finalData.length);
    console.log(finalData.toString());
  });

});

in my case, some characters like " , :"'{}[] " maybe corrupt the JSON format, so use try json.loads(str) except to check your input

To get the full file path of a selected file or files, then you need to use FileName property for one file or FileNames property for multiple files.

var file = choofdlog.FileName; // for one file

or for multiple files

var files = choofdlog.FileNames; // for multiple files.

To get the directory of the file, you can use Path.GetDirectoryName
Here is Jon Keet's answer to a similar question about getting directories from path

Yes, using DateFormat.getDateInstance(int style, Locale aLocale) This displays the current date in a locale-specific way.

So, for example:

DateFormat df = DateFormat.getDateInstance(DateFormat.SHORT, yourLocale);
String formattedDate = df.format(yourDate);

See the docs for the exact meaning of the style parameter (SHORT, MEDIUM, etc)

If you want to use spring jdbctemplate and don't want to deal with connection staff, you can use following:

jdbcTemplate.query("select * from books", new RowCallbackHandler() {
        public void processRow(ResultSet resultSet) throws SQLException {
            ResultSetMetaData rsmd = resultSet.getMetaData();
            for (int i = 1; i <= rsmd.getColumnCount(); i++ ) {
                String name = rsmd.getColumnName(i);
                // Do stuff with name
            }
        }
    });

If you have your CSS in the internal file storage you can use

//Get a reference to your webview
WebView web = (WebView)findViewById(R.id.webby);

// Prepare some html, it is formated with css loaded from the file style.css
String webContent = "<!DOCTYPE html><html><head><meta charset=\"UTF-8\"><link rel=\"stylesheet\" href=\"style.css\"></head>"
                      + "<body><div class=\"running\">I am a text rendered with INDIGO</div></body></html>";

//get and format the path pointing to the internal storage
String internalFilePath = "file://" + getFilesDir().getAbsolutePath() + "/";

//load the html with the baseURL, all files relative to the baseURL will be found 
web.loadDataWithBaseURL(internalFilePath, webContent, "text/html", "UTF-8", "");

All you have to do to overcome this problem is to add android:singleLine="true" to the checkBox in your android xml layout:

<CheckBox 
   android:id="@+id/your_check_box"
   android:layout_width="match_parent"
   android:layout_height="wrap_content"
   android:singleLine="true"
   android:background="@android:color/transparent"
   android:text="@string/your_string"/>

and nothing special will be added programmatically.

You just need to put your war file in webapps and then start your server.

it will get deployed.

otherwise you can also use tomcat manager a webfront to upload & deploy your war remotely.

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

Start by defining a generic function pointer type:

typedef int (__stdcall* func_ptr_t)();

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

func_ptr_t func_ptr [DLL_FUNCTIONS_N];

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

int result = dll_add(1, 1);

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

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

This is my very simple c++ program to list down the prime numbers in between 2 and 100.

for(int j=2;j<=100;++j)
{
    int i=2;
    for(;i<=j-1;i++)
    {
        if(j%i == 0)
            break;
    }

    if(i==j && i != 2)
        cout<<j<<endl;
}

To get the file size of pages on the web I built a javascript bookmarklet to do the trick. It alerts the size in kb's. Change the alert to a prompt if you want to copy the filesize.

Here's the bookmarklet code for the alert.

<a href="javascript:a=document.getElementsByTagName('HTML')[0].outerHTML;b=a.length/1024;c=Math.round(b);alert(c+' kb');">Doc Size</a>

Here's the bookmarklet code for the prompt.

<a href="javascript:a=document.getElementsByTagName('HTML')[0].outerHTML;b=a.length/1024;c=Math.round(b);prompt('Page Size',c+' kb');">Doc Size</a>

See it in action at http://bookmarklets.to.g0.to/filesize.php

use auto and min or max width like this:

td {
max-width:50px;
width:auto;
min-width:10px;
}

Try also to use the cksum command:

chk1=`cksum <file1> | awk -F" " '{print $1}'`
chk2=`cksum <file2> | awk -F" " '{print $1}'`

if [ $chk1 -eq $chk2 ]
then
  echo "File is identical"
else
  echo "File is not identical"
fi

The cksum command will output the byte count of a file. See 'man cksum'.

I had the same problem. You have to write mysql -u root -p

NOT mysql or mysql -u root -p root_password

The running the impdp command to produce an sqlfile, you will need to run it as a user which has the DATAPUMP_IMP_FULL_DATABASE role.

Or... run it as a low privileged user and use the MASTER_ONLY=YES option, then inspect the master table. e.g.

select value_t 
from SYS_IMPORT_TABLE_01 
where name = 'CLIENT_COMMAND' 
and process_order = -59;

col object_name for a30
col processing_status head STATUS for a6
col processing_state head STATE for a5
select distinct
  object_schema,
  object_name,
  object_type,
  object_tablespace,
  process_order,
  duplicate,
  processing_status,
  processing_state
from sys_import_table_01
where process_order > 0
and object_name is not null
order by object_schema, object_name

import finplot as fplt
fplt.candlestick_ochl(df[['Open','Close','High','Low']])
fplt.show()

If you want to delete ionic and cordova at same time.Run this code in cmd

npm uninstall -g ionic cordova

You can also pass the function of a struct, like:

    package main
    // define struct
    type Apple struct {}
    
    // return apple's color
    func (Apple) GetColor() string {
         return "Red" 
    }
    
    func main () {
        // instantiate
        myApple := Apple{}
        
        // put the func in a variable
        theFunc := myApple.GetColor
        
        // execute the variable as a function
        color := theFunc()
    
        print(color)
    }

output will be "Red", check on the playground

If the items are numerically ordered, use the key() function to determine the index of the current item and compare it to the length. You'd have to use next() or prev() to cycle through items in a while loop instead of a for loop:

$length = sizeOf($arr);
while (key(current($arr)) != $length-1) {
    $v = current($arr); doSomething($v); //do something if not the last item
    next($myArray); //set pointer to next item
}

See the crypto.createHash() function and the associated hash.update() and hash.digest() functions:

var crypto = require('crypto')
var shasum = crypto.createHash('sha1')
shasum.update('foo')
shasum.digest('hex') // => "0beec7b5ea3f0fdbc95d0dd47f3c5bc275da8a33"

I know you already have several answers, but I was on a similar situation where my team didn't want to depend on a heavy libraries or anything related to bootstrap since we are using material so I made our own autocomplete control, using material-like styles, you can use my autocomplete or at least you can give a look to give you some guiadance, there was not much documentation on simple examples on how to upload your components to be shared on NPM.

You need to add javaw.exe full path with forward slash i.e. / instead \ to eclipse.ini even you are on Windows. Like below:

-vm
C:/Program Files/Java/jdk-14/bin/javaw.exe

Also the above lines must be placed before -vmargs.

You have to open database connection, not workbench file with schema. It looks a bit wierd, but it makes sense when you realize what you are editing.

So, go to home tab, double click database connection (create it if you don't have it yet) and have fun.

I am using this and it works for me with Jquery:

Jquery:

var checkbox = $('[name="remember"]');

if (checkbox.is(':checked'))
{
    console.log('The checkbox is checked');
}else
{
    console.log('The checkbox is not checked');
}

Is very simple, but work's.

$rootScope basically functions as an event listener and dispatcher.

To answer the question of how it is used, it used in conjunction with rootScope.$on;

$rootScope.$broadcast("hi");

$rootScope.$on("hi", function(){
    //do something
});

However, it is a bad practice to use $rootScope as your own app's general event service, since you will quickly end up in a situation where every app depends on $rootScope, and you do not know what components are listening to what events.

The best practice is to create a service for each custom event you want to listen to or broadcast.

.service("hiEventService",function($rootScope) {
    this.broadcast = function() {$rootScope.$broadcast("hi")}
    this.listen = function(callback) {$rootScope.$on("hi",callback)}
})

I may get bitten by this one but I think that it's personal preference. I can't find any reference in the docs to each() being different than keys() or values() (other than the obvious "they return different things" answer. In fact the docs state the use the same iterator and they all return actual list values instead of copies of them, and that modifying the hash while iterating over it using any call is bad.

All that said, I almost always use keys() because to me it is usually more self documenting to access the key's value via the hash itself. I occasionally use values() when the value is a reference to a large structure and the key to the hash was already stored in the structure, at which point the key is redundant and I don't need it. I think I've used each() 2 times in 10 years of Perl programming and it was probably the wrong choice both times =)

Try this one:

declare @StartDate datetime, @EndDate datetime

select @StartDate = '2016-05-04 10:23:41.083', @EndDate='2016-05-04 10:25:26.053'

select CAST(DateDiff(MI, @startDate, @EndDate)/60 AS varchar)+':'+Cast(DateDiff(MI, @startDate, @EndDate)%60 AS varchar)+':'+cast(DateDiff(s, @startDate, @EndDate)%60 AS varchar) as [hh:mm:ss]

You can remove a specific event handler that was attached by on, using off

$("#ID").on ("eventName", additionalCss, handlerFunction);

// to remove the specific handler
$("#ID").off ("eventName", additionalCss, handlerFunction);

Using this, you will remove only handlerFunction
Another good practice, is to set a nameSpace for multiple attached events

$("#ID").on ("eventName1.nameSpace", additionalCss, handlerFunction1);
$("#ID").on ("eventName2.nameSpace", additionalCss, handlerFunction2);
// ...
$("#ID").on ("eventNameN.nameSpace", additionalCss, handlerFunctionN);

// and to remove handlerFunction from 1 to N, just use this
$("#ID").off(".nameSpace");

Make sure your app is public. Click on + Add product Now go to products => Facebook Login Now do the following:

Valid OAuth redirect URIs : example.com/

Deauthorize Callback URL : https://example.com/facebookapp

While I tried the approach above, it becomes a complete disaster with mvc. Your controller passing a model and your view using a strongly typed model become too difficult to work with.

Get your Dataset into a List ..... I have a repository pattern and here is an example of getting a dataset from an old school asmx web service private readonly CISOnlineSRVDEV.ServiceSoapClient _ServiceSoapClient;

    public Get_Client_Repository()
        : this(new CISOnlineSRVDEV.ServiceSoapClient())
    {

    }
    public Get_Client_Repository(CISOnlineSRVDEV.ServiceSoapClient serviceSoapClient)
    {
        _ServiceSoapClient = serviceSoapClient;
    }


    public IEnumerable<IClient> GetClient(IClient client)
    {
        // ****  Calling teh web service with passing in the clientId and returning a dataset
        DataSet dataSet = _ServiceSoapClient.get_clients(client.RbhaId,
                                                        client.ClientId,
                                                        client.AhcccsId,
                                                        client.LastName,
                                                        client.FirstName,
                                                        "");//client.BirthDate.ToString());  //TODO: NEED TO FIX

        // USE LINQ to go through the dataset to make it easily available for the Model to display on the View page
        List<IClient> clients = (from c in dataSet.Tables[0].AsEnumerable()
                                 select new Client()
                                 {
                                     RbhaId = c[5].ToString(),
                                     ClientId = c[2].ToString(),
                                     AhcccsId = c[6].ToString(),
                                     LastName = c[0].ToString(), // Add another field called   Sex M/F  c[4]
                                     FirstName = c[1].ToString(),
                                     BirthDate = c[3].ToDateTime()  //extension helper  ToDateTime()
                                 }).ToList<IClient>();

        return clients;

    }

Then in the Controller I'm doing this

IClient client = (IClient)TempData["Client"];

// Instantiate and instance of the repository 
var repository = new Get_Client_Repository();
// Set a model object to return the dynamic list from repository method call passing in the parameter data
var model = repository.GetClient(client);

// Call the View up passing in the data from the list
return View(model);

Then in the View it is easy :

@model IEnumerable<CISOnlineMVC.DAL.IClient>

@{
    ViewBag.Title = "CLIENT ALL INFORMATION";
}

<h2>CLIENT ALL INFORMATION</h2>

<table>
    <tr>
        <th></th>
        <th>Last Name</th>
        <th>First Name</th>
        <th>Client ID</th>
        <th>DOB</th>
        <th>Gender</th>
        <th>RBHA ID</th>
        <th>AHCCCS ID</th>
    </tr>

@foreach (var item in Model) {
    <tr>
        <td>
            @Html.ActionLink("Select", "ClientDetails", "Cis", new { id = item.ClientId }, null) |
        </td>
        <td>
            @item.LastName
        </td>
        <td>
            @item.FirstName
        </td>
         <td>
            @item.ClientId
        </td>
         <td>
            @item.BirthDate
        </td>
         <td>
            Gender @* ADD in*@
        </td>
         <td>
            @item.RbhaId
        </td>
         <td>
            @item.AhcccsId
        </td>
    </tr>
}

</table>

Update your node and it will resolve this problem.

Maybe not the most efficient way. But you could convert the list into a vector.

#include <list>
#include <vector>

list<Object> myList;

vector<Object> myVector(myList.begin(), myList.end());

Then access the vector using the [x] operator.

auto x = MyVector[0];

You could put that in a helper function:

#include <memory>
#include <vector>
#include <list>

template<class T>
shared_ptr<vector<T>> 
ListToVector(list<T> List) {
shared_ptr<vector<T>> Vector {
        new vector<string>(List.begin(), List.end()) }
return Vector;
}

Then use the helper funciton like this:

auto MyVector = ListToVector(Object);
auto x = MyVector[0];

The issue here is that input() returns a string in Python 3.x, so when you do your comparison, you are comparing a string and an integer, which isn't well defined (what if the string is a word, how does one compare a string and a number?) - in this case Python doesn't guess, it throws an error.

To fix this, simply call int() to convert your string to an integer:

int(input(...))

As a note, if you want to deal with decimal numbers, you will want to use one of float() or decimal.Decimal() (depending on your accuracy and speed needs).

Note that the more pythonic way of looping over a series of numbers (as opposed to a while loop and counting) is to use range(). For example:

def main():
    print("Let me Retire Financial Calculator")
    deposit = float(input("Please input annual deposit in dollars: $"))
    rate = int(input ("Please input annual rate in percentage: %")) / 100
    time = int(input("How many years until retirement?"))
    value = 0
    for x in range(1, time+1):
        value = (value * rate) + deposit
        print("The value of your account after" + str(x) + "years will be $" + str(value))

I am pretty new to all of this, but I found that if the script is started via CScript.exe (console scripting host) there is no window popping up on exec(): so when running:

cscript myscript.vbs //nologo

any .Exec() calls in the myscript.vbs do not open an extra window, meaning that you can use the first variant of your original solution (using exec).

(Note that the two forward slashes in the above code are intentional, see cscript /?)

Swift 4 & Swift 5:

You need to add target for that button.

myButton.addTarget(self, action: #selector(connected(sender:)), for: .touchUpInside)

And of course you need to set tag of that button since you are using it.

myButton.tag = indexPath.row

You can achieve this by subclassing UITableViewCell. Use it in interface builder, drop a button on that cell, connect it via outlet and there you go.

To get the tag in the connected function:

@objc func connected(sender: UIButton){
    let buttonTag = sender.tag
}

You can add them like this

  Route::get('company/{name}', 'PublicareaController@companydetails');

You can use this piece of code:

  <iframe src="http://example.com" frameborder="0" style="overflow:hidden;overflow-x:hidden;overflow-y:hidden;height:100%;width:100%;position:absolute;top:0%;left:0px;right:0px;bottom:0px" height="100%" width="100%"></iframe>

Please note on iPad Safari, NoviceCoding's solution won't work if you have -webkit-overflow-scrolling: touch; somewhere in your CSS. The solution is either removing all the occurrences of -webkit-overflow-scrolling: touch; or putting -webkit-overflow-scrolling: auto; with NoviceCoding's solution.

The Mozilla Developer Network provides the following explanation:

1. Create an event using event = document.createEvent("KeyboardEvent")
2. Init the keyevent

using:

event.initKeyEvent (type, bubbles, cancelable, viewArg, 
       ctrlKeyArg, altKeyArg, shiftKeyArg, metaKeyArg, 
           keyCodeArg, charCodeArg)

3. Dispatch the event using yourElement.dispatchEvent(event)

I don't see the last one in your code, maybe that's what you're missing. I hope this works in IE as well...

You can use UITableViewRowAction's backgroundColor to set custom image or view. The trick is using UIColor(patternImage:).

Basically the width of UITableViewRowAction area is decided by its title, so you can find a exact length of title(or whitespace) and set the exact size of image with patternImage.

To implement this, I made a UIView's extension method.

func image() -> UIImage {
    UIGraphicsBeginImageContextWithOptions(bounds.size, isOpaque, 0)
    guard let context = UIGraphicsGetCurrentContext() else {
        return UIImage()
    }
    layer.render(in: context)
    let image = UIGraphicsGetImageFromCurrentImageContext()
    UIGraphicsEndImageContext()
    return image!
}

and to make a string with whitespace and exact length,

fileprivate func whitespaceString(font: UIFont = UIFont.systemFont(ofSize: 15), width: CGFloat) -> String {
    let kPadding: CGFloat = 20
    let mutable = NSMutableString(string: "")
    let attribute = [NSFontAttributeName: font]
    while mutable.size(attributes: attribute).width < width - (2 * kPadding) {
        mutable.append(" ")
    }
    return mutable as String
}

and now, you can create UITableViewRowAction.

func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]? {
    let whitespace = whitespaceString(width: kCellActionWidth)
    let deleteAction = UITableViewRowAction(style: .`default`, title: whitespace) { (action, indexPath) in
        // do whatever you want
    }

    // create a color from patter image and set the color as a background color of action
    let kActionImageSize: CGFloat = 34
    let view = UIView(frame: CGRect(x: 0, y: 0, width: kCellActionWidth, height: kCellHeight))
    view.backgroundColor = UIColor.white
    let imageView = UIImageView(frame: CGRect(x: (kCellActionWidth - kActionImageSize) / 2,
                                              y: (kCellHeight - kActionImageSize) / 2,
                                              width: 34,
                                              height: 34))
    imageView.image = UIImage(named: "x")
    view.addSubview(imageView)
    let image = view.image()

    deleteAction.backgroundColor = UIColor(patternImage: image)

    return [deleteAction]
}

The result will look like this.

Another way to do this is to import custom font which has the image you want to use as a font and use UIButton.appearance. However this will affect other buttons unless you manually set other button's font.

From iOS 11, it will show this message [TableView] Setting a pattern color as backgroundColor of UITableViewRowAction is no longer supported.. Currently it is still working, but it wouldn't work in the future update.

==========================================

For iOS 11+, you can use:

func tableView(_ tableView: UITableView, trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
  let deleteAction = UIContextualAction(style: .normal, title: "Delete") { (action, view, completion) in
    // Perform your action here
      completion(true)
  }

  let muteAction = UIContextualAction(style: .normal, title: "Mute") { (action, view, completion) in
    // Perform your action here
    completion(true)
  }

  deleteAction.image = UIImage(named: "icon.png")
  deleteAction.backgroundColor = UIColor.red
  return UISwipeActionsConfiguration(actions: [deleteAction, muteAction])
} 

You can use this function, ORACLE DB

 public string getMaximumSequenceOfUser(string columnName, string tableName, string username)
    {
        string result = "";
        var query = string.Format("Select MAX ({0})from {1} where CREATED_BY = {2}", columnName, tableName, username.ToLower());

        OracleConnection conn = new OracleConnection(_context.Database.Connection.ConnectionString);
        OracleCommand cmd = new OracleCommand(query, conn);
        try
        {
            conn.Open();
            OracleDataReader dr = cmd.ExecuteReader();
            dr.Read();
            result = dr[0].ToString();
            dr.Dispose();
        }
        finally
        {
            conn.Close();
        }
        return result;
    }

The concept of leading zero is meaningless for an int, which is what you have. It is only meaningful, when printed out or otherwise rendered as a string.

Console.WriteLine("{0:0000000}", FileRecordCount);

Forgot to end the double quotes!

I found an excellent utility that is configurable at https://github.com/acch/genfiles.

It fills the target file with random data, so there are no problems with sparse files, and for my purposes (testing compression algorithms) it gives a nice level of white noise.

ImageArtist is a pure gd wrapper authored by me, this enables you to do complex image manipulations insanely easy, for your question solution can be done using very few steps using this powerful library.

here is a sample code.

$img1 = new Image("./cover.jpg");
$img2 = new Image("./box.png");
$img2->merge($img1,9,9);
$img2->save("./merged.png",IMAGETYPE_PNG);

This is how my result looks like.

Alt+# comments out the current line. It will be available in history if needed.

The simplest approach would be to edit the webserver, most likely an Apache2 installation, configuration and give phpmyadmin a different name.

A second approach would be to limit the IP addresses from where phpmyadmin may be accessed (e.g. only local lan or localhost).

I was having this problem too. For me, I couldn't start/stop openfire (it said it was stopped, but everything was still running)

sudo /etc/init.d/openfire stop
sudo /etc/init.d/openfire start

Also, restarting apache did not help either

sudo /etc/init.d/apache2 restart

The errors were inside:

/opt/openfire/logs/stderror.log
Error creating server listener on port 5269: Address already in use
Error creating server listener on port 5222: Address already in use

The way I fixed this, I had to actually turn off the server inside the admin area for my host.

Try this

string[] keys = Request.Form.AllKeys;
var value = "";
for (int i= 0; i < keys.Length; i++) 
{
   // here you get the name eg test[0].quantity
   // keys[i];
   // to get the value you use
   value = Request.Form[keys[i]];
}

Your example Alamofire.request(.POST, "http://mywebsite.com/post-request", parameters: ["foo": "bar"]) already contains "foo=bar" string as its body. But if you really want string with custom format. You can do this:

Alamofire.request(.POST, "http://mywebsite.com/post-request", parameters: [:], encoding: .Custom({
            (convertible, params) in
            var mutableRequest = convertible.URLRequest.copy() as NSMutableURLRequest
            mutableRequest.HTTPBody = "myBodyString".dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)
            return (mutableRequest, nil)
        }))

Note: parameters should not be nil

UPDATE (Alamofire 4.0, Swift 3.0):

In Alamofire 4.0 API has changed. So for custom encoding we need value/object which conforms to ParameterEncoding protocol.

extension String: ParameterEncoding {

    public func encode(_ urlRequest: URLRequestConvertible, with parameters: Parameters?) throws -> URLRequest {
        var request = try urlRequest.asURLRequest()
        request.httpBody = data(using: .utf8, allowLossyConversion: false)
        return request
    }

}

Alamofire.request("http://mywebsite.com/post-request", method: .post, parameters: [:], encoding: "myBody", headers: [:])

As the error idnicates - "This happens when the section is locked at a parent level". To unlock the section you can use appcmd.exe and execute the following command:

%windir%\system32\inetsrv\appcmd.exe unlock config -section:system.webServer/handlers -commitpath:apphost

For more information on about section locking and what a parent configuration context is refer to IIS documentation.

One line solution

new Date(new Date(1422524805305).getTime() - 330*60*1000)

Instead of 1422524805305, use the timestamp in milliseconds Instead of 330, use your timezone offset in minutes wrt. GMT (eg India +5:30 is 5*60+30 = 330 minutes)

In your config.ini file of eclipse eclipse\configuration\config.ini check this three things:

osgi.framework=file\:plugins\\org.eclipse.osgi_3.4.2.R34x_v20080826-1230.jar
osgi.bundles=reference\:file\:org.eclipse.equinox.simpleconfigurator_1.0.0.v20080604.jar@1\:start
org.eclipse.equinox.simpleconfigurator.configUrl=file\:org.eclipse.equinox.simpleconfigurator\\bundles.info

And check whether these jars are in place or not, the jar files depend upon your version of eclipse .

You should know that it is not possible to directly run a DDL statement like you do for DML from a PL/SQL block because PL/SQL does not support late binding directly it only support compile time binding which is fine for DML. hence to overcome this type of problem oracle has provided a dynamic SQL approach which can be used to execute the DDL statements.The dynamic sql approach is about parsing and binding of sql string at the runtime. Also you should rememder that DDL statements are by default auto commit hence you should be careful about any of the DDL statement using the dynamic SQL approach incase if you have some DML (which needs to be commited explicitly using TCL) before executing the DDL in the stored proc/function.

You can use any of the following dynamic sql approach to execute a DDL statement from a pl/sql block.

1) Execute immediate

2) DBMS_SQL package

3) DBMS_UTILITY.EXEC_DDL_STATEMENT (parse_string IN VARCHAR2);

Hope this answers your question with explanation.

I was getting these errors too and was stumped. After reading and trying the two answers above, I was still getting the error.

However,I checked the processes tab of Task Manager to find a rogue copy of 'eclipse.exe *32' that the UI didn' t show as running. I guess this should have been obvious as the error does suggest that the reason the emulator/phone cannot connect is because it's already established a connection with the second copy.

Long story short, make sure via Task Manager that no other Eclipse instances are running before resorting to a PC restart!

If you have a lateinit property in one class and need to check if it is initialized from another class

if(foo::file.isInitialized) // this wouldn't work

The workaround I have found is to create a function to check if the property is initialized and then you can call that function from any other class.

Example:

class Foo() {

    private lateinit var myFile: File

    fun isFileInitialised() = ::file.isInitialized
}

 // in another class
class Bar() {

    val foo = Foo()

    if(foo.isFileInitialised()) // this should work
}

function getURLParameter(name) {
  return decodeURIComponent((new RegExp('[?|&]' + name + '=' + '([^&;]+?)(&|#|;|$)').exec(location.search) || [null, ''])[1].replace(/\+/g, '%20')) || null;
}

So you can use:

myvar = getURLParameter('myvar');

It is not recommended, but you can still use this. Better go with this solution in case you need to quit the app.

According to me, the best solution is to finish every activity in your app like below.

Step 1. Maintain a static variable in mainactivity. Say,

public static boolean isQuit = false;

Step 2. On click event of an button, set this variable to true.

mainactivity.isQuit = true;
finish();

Step 3. And in every activity of your application, have the onrestart method as below.

@Override
protected void onRestart() {
    // TODO Auto-generated method stub
    super.onRestart();
    if(mainactivity.isQuit)
        finish();
}

 else if (File.Exists(path)) 
{ 
  using (StreamWriter w = File.AppendText(path))
        {
            w.WriteLine("The next line!"); 
            w.Close();
        }
 } 

For nginx/1.4.6 (Ubuntu)

Python has names which are mapped to objects in a hashmap called a namespace. At any instant in time, a name always refers to exactly one object, but a single object can be referred to by any arbitrary number of names. Given a name, it is very efficient for the hashmap to look up the single object which that name refers to. However given an object, which as mentioned can be referred to by multiple names, there is no efficient way to look up the names which refer to it. What you have to do is iterate through all the names in the namespace and check each one individually and see if it maps to your given object. This can easily be done with a list comprehension:

[k for k,v in locals().items() if v is myobj]

This will evaluate to a list of strings containting the names of all local "variables" which are currently mapped to the object myobj.

>>> a = 1
>>> this_is_also_a = a
>>> this_is_a = a
>>> b = "ligma"
>>> c = [2,3, 534]
>>> [k for k,v in locals().items() if v is a]

['a', 'this_is_also_a', 'this_is_a']

Of course locals() can be substituted with any dict that you want to search for names that point to a given object. Obviously this search can be slow for very large namespaces because they must be traversed in their entirety.

I prefer to avoid using Ajax.BeginForm helper and do an Ajax call with JQuery. In my experience it is easier to maintain code written like this. So below are the details:

Models

public class ManagePeopleModel
{
    public List<PersonModel> People { get; set; }
    ... any other properties
}

public class PersonModel
{
    public int Id { get; set; }
    public string Name { get; set; }
    public int Age { get; set; }
    ... any other properties
}

Parent View

This view contains the following things:

• records of people to iterate through
• an empty div that will be populated with a modal when a Person needs to be edited
• some JavaScript handling all ajax calls

@model ManagePeopleModel

<h1>Manage People</h1>

@using(var table = Html.Bootstrap().Begin(new Table()))
{
    foreach(var person in Model.People)
    {
        <tr>
            <td>@person.Id</td>
            <td>@Person.Name</td>
            <td>@person.Age</td>
            <td>@html.Bootstrap().Button().Text("Edit Person").Data(new { @id = person.Id }).Class("btn-trigger-modal")</td>
        </tr>
    }
}

@using (var m = Html.Bootstrap().Begin(new Modal().Id("modal-person")))
{

}

@section Scripts
{
    <script type="text/javascript">
        // Handle "Edit Person" button click.
        // This will make an ajax call, get information for person,
        // put it all in the modal and display it
        $(document).on('click', '.btn-trigger-modal', function(){
            var personId = $(this).data('id');
            $.ajax({
                url: '/[WhateverControllerName]/GetPersonInfo',
                type: 'GET',
                data: { id: personId },
                success: function(data){
                    var m = $('#modal-person');
                    m.find('.modal-content').html(data);
                    m.modal('show');
                }
            });
        });

        // Handle submitting of new information for Person.
        // This will attempt to save new info
        // If save was successful, it will close the Modal and reload page to see updated info
        // Otherwise it will only reload contents of the Modal
        $(document).on('click', '#btn-person-submit', function() {
            var self = $(this);
            $.ajax({
                url: '/[WhateverControllerName]/UpdatePersonInfo',
                type: 'POST',
                data: self.closest('form').serialize(),
                success: function(data) {
                    if(data.success == true) {
                        $('#modal-person').modal('hide');
                        location.reload(false)
                    } else {
                        $('#modal-person').html(data);
                    }
                }
            });
        });
    </script>
}

Partial View

This view contains a modal that will be populated with information about person.

@model PersonModel
@{
    // get modal helper
    var modal = Html.Bootstrap().Misc().GetBuilderFor(new Modal());
}

@modal.Header("Edit Person")
@using (var f = Html.Bootstrap.Begin(new Form()))
{
    using (modal.BeginBody())
    {
        @Html.HiddenFor(x => x.Id)
        @f.ControlGroup().TextBoxFor(x => x.Name)
        @f.ControlGroup().TextBoxFor(x => x.Age)
    }
    using (modal.BeginFooter())
    {
        // if needed, add here @Html.Bootstrap().ValidationSummary()
        @:@Html.Bootstrap().Button().Text("Save").Id("btn-person-submit")
        @Html.Bootstrap().Button().Text("Close").Data(new { dismiss = "modal" })
    }
}

Controller Actions

public ActionResult GetPersonInfo(int id)
{
    var model = db.GetPerson(id); // get your person however you need
    return PartialView("[Partial View Name]", model)
}

public ActionResult UpdatePersonInfo(PersonModel model)
{
    if(ModelState.IsValid)
    {
        db.UpdatePerson(model); // update person however you need
        return Json(new { success = true });
    }
    // else
    return PartialView("[Partial View Name]", model);
}

You can overflow:hidden to your #content. Write like this:

#content
{
    min-width:700px;
    margin-left:10px;
    overflow:hidden;
    background-color:AppWorkspace;
}

Here is what I did recently in PHP on one of my bigger systems:

1. User inputs newsletter text and selects the recipients (which generates a query to retrieve the email addresses for later).

2. Add the newsletter text and recipients query to a row in mysql table called *email_queue*

   • (The table email_queue has the columns "to" "subject" "body" "priority")

3. I created another script, which runs every minute as a cron job. It uses the SwiftMailer class. This script simply:

   • during business hours, sends all email with priority == 0

   • after hours, send other emails by priority

Depending on the hosts settings, I can now have it throttle using standard swiftmailers plugins like antiflood and throttle...

$mailer->registerPlugin(new Swift_Plugins_AntiFloodPlugin(50, 30));

and

$mailer->registerPlugin(new Swift_Plugins_ThrottlerPlugin( 100, Swift_Plugins_ThrottlerPlugin::MESSAGES_PER_MINUTE ));

etc, etc..

I have expanded it way beyond this pseudocode, with attachments, and many other configurable settings, but it works very well as long as your server is setup correctly to send email. (Probably wont work on shared hosting, but in theory it should...) Swiftmailer even has a setting

$message->setReturnPath

Which I now use to track bounces...

Happy Trails! (Happy Emails?)

I think the fastest solution is

select * from table where rand() <= .3

Here is why I think this should do the job.

• It will create a random number for each row. The number is between 0 and 1
• It evaluates whether to display that row if the number generated is between 0 and .3 (30%).

This assumes that rand() is generating numbers in a uniform distribution. It is the quickest way to do this.

I saw that someone had recommended that solution and they got shot down without proof.. here is what I would say to that -

• This is O(n) but no sorting is required so it is faster than the O(n lg n)

• mysql is very capable of generating random numbers for each row. Try this -

  select rand() from INFORMATION_SCHEMA.TABLES limit 10;

Since the database in question is mySQL, this is the right solution.

I got the same error and ended up using a pre-built distribution of numpy available in SourceForge (similarly, a distribution of matplotlib can be obtained).

Builds for both 32-bit 2.7 and 3.3/3.4 are available.
PyCharm detected them straight away, of course.

I know this is an old question, but I wanted to make sure a couple of other options are noted.

Since you can't store a TimeSpan greater than 24 hours in a time sql datatype field; a couple of other options might be.

1. Use a varchar(xx) to store the ToString of the TimeSpan. The benefit of this is the precision doesn't have to be baked into the datatype or the calculation, (seconds vs milliseconds vs days vs fortnights) All you need to to is use TimeSpan.Parse/TryParse. This is what I would do.

2. Use a second date, datetime or datetimeoffset, that stores the result of first date + timespan. Reading from the db is a matter of TimeSpan x = SecondDate - FirstDate. Using this option will protect you for other non .NET data access libraries access the same data but not understanding TimeSpans; in case you have such an environment.

moment.js has some really nice convenience methods to manipulate date objects

The .subtract method, allows you to subtract a certain amount of time units from a date, by providing the amount and a timeunit string.

var now = new Date();
// Sun Jan 22 2017 17:12:18 GMT+0200 ...
var olderDate = moment(now).subtract(3, 'minutes').toDate();
// Sun Jan 22 2017 17:09:18 GMT+0200 ...

I'm a big fan of hdf5 for storing large numpy arrays. There are two options for dealing with hdf5 in python:

http://www.pytables.org/

http://www.h5py.org/

Both are designed to work with numpy arrays efficiently.

I want to shed some more light on the actual way of doing a Splash screen in Flutter.

I followed a little bit the trace here and I saw that things aren't looking so bad about the Splash Screen in Flutter.

Maybe most of the devs (like me) are thinking that there isn't a Splash screen by default in Flutter and they need to do something about that. There is a Splash screen, but it's with white background and nobody can understand that there is already a splash screen for iOS and Android by default.

The only thing that the developer needs to do is to put the Branding image in the right place and the splash screen will start working just like that.

Here is how you can do it step by step:

First on Android (because is my favorite Platform :) )

1. Find the "android" folder in your Flutter project.

2. Browse to the app -> src -> main -> res folder and place all of the variants of your branding image in the corresponding folders. For example:

• the image with density 1 needs to be placed in mipmap-mdpi,
• the image with density 1.5 needs to be placed in mipmap-hdpi,
• the image with density 2 needs to be placed in mipmap-xhdpi,
• the image with density 3 needs to be placed in mipmap-xxhdpi,
• the image with density 4 needs to be placed in mipmap-xxxhdpi,

By default in the android folder there isn't a drawable-mdpi, drawable-hdpi, etc., but we can create them if we want. Because of that fact the images need to be placed in the mipmap folders. Also the default XML code about the Splash screen (in Android) is going to use @mipmap, instead of @drawable resource (you can change it if you want).

3. The last step on Android is to uncomment some of the XML code in drawable/launch_background.xml file. Browse to app -> src -> main -> res-> drawable and open launch_background.xml. Inside this file, you shall see why the Slash screen background is white. To apply the branding image which we placed in step 2, we have to uncomment some of the XML code in your launch_background.xml file. After the change, the code should look like:

    <!--<item android:drawable="@android:color/white" />-->
   
    <item>
   
        <bitmap
            android:gravity="center"
            android:src="@mipmap/your_image_name" />
   
    </item>
   

Please pay attention that we comment the XML code for the white background and uncomment the code about the mipmap image. If somebody is interested the file launch_background.xml is used in styles.xml file.

Second on iOS:

1. Find the "ios" folder in your Flutter project.

2. Browse to Runner -> Assets.xcassets -> LaunchImage.imageset. There should be LaunchImage.png, [email protected], etc. Now you have to replace these images with your branding image variants. For example:

• the image with density 1 needs to override LaunchImage.png,
• the image with density 2 needs to override [email protected],
• the image with density 3 needs to override [email protected],
• the image with density 4 needs to override [email protected],

If I am not wrong [email protected] doesn't exist by default, but you can easily create one. If [email protected] doesn't exist, you have to declare it in the Contents.json file as well, which is in the same directory as the images. After the change my Contents.json file looks like this :

{
  "images" : [
    {
      "idiom" : "universal",
      "filename" : "LaunchImage.png",
      "scale" : "1x"
    },
    {
      "idiom" : "universal",
      "filename" : "[email protected]",
      "scale" : "2x"
    },
    {
      "idiom" : "universal",
      "filename" : "[email protected]",
      "scale" : "3x"
    },
    {
      "idiom" : "universal",
      "filename" : "[email protected]",
      "scale" : "4x"
    }
  ],
  "info" : {
    "version" : 1,
    "author" : "xcode"
  }
}

That should be all you need, next time when you run your app, on Android or iOS you should have the right Splash Screen with the branding image which you added.

Thanks

Use

Try_convert(float,[Value])

See https://raresql.com/2013/04/26/sql-server-how-to-convert-varchar-to-float/

To solve this issue you need to run your application by increasing the memory limit by using the option --max_old_space_size. By default the memory limit of Node.js is 512 mb.

node --max_old_space_size=2000  server.js 

In my case I faced that error while parsing an email. I got the attachment as base64 string and extract it via re.search. Eventually there was a strange additional substring at the end.

--_=ic0008m4wtZ4TqBFd+sXC8--

When I deleted --_=ic0008m4wtZ4TqBFd+sXC8-- and strip the string then parsing was fixed up.

So my advise is make sure that you are decoding a correct base64 string.

For anyone trying to

• "show text under marker on google maps", or
• "Google Maps Marker Label With Multiple Characters"

...in 2019, it's worth noting some of the code referenced here no longer exists (officially). Google discontinued support for the "MarkerWithLabel" project a long time ago. It was originally hosted on Google code here, now it's unofficially hosted on Github here.

But there is another project Google maintained until 2016, called "MapLabel"s. That approach is different (and arguably better). You create a separate map label object with the same origin as the marker instead of adding a mapLabel option to the marker itself. You can make a marker with label with multiple characters using js-marker-label.

I was intrigued by the answer from @Jerry Coffin, which suggested that the ordered map would exhibit performance increases on long strings, after some experimentation (which can be downloaded from pastebin), I've found that this seems to hold true only for collections of random strings, when the map is initialised with a sorted dictionary (which contain words with considerable amounts of prefix-overlap), this rule breaks down, presumably because of the increased tree depth necessary to retrieve value. The results are shown below, the 1st number column is insert time, 2nd is fetch time.

For Apache 2.4, you would use the Require IP directive. So to only allow machines from the 192.168.0.0/24 network (range 192.168.0.0 - 192.168.0.255)

<VirtualHost *:80>
    <Location />
      Require ip 192.168.0.0/24
    </Location>
    ...
</VirtualHost>

And if you just want the localhost machine to have access, then there's a special Require local directive.

The local provider allows access to the server if any of the following conditions is true:

• the client address matches 127.0.0.0/8
• the client address is ::1
• both the client and the server address of the connection are the same

This allows a convenient way to match connections that originate from the local host:

<VirtualHost *:80>
    <Location />
      Require local
    </Location>
    ...
</VirtualHost>

use sudo with the command:

sudo apt-get remove --purge mongodb  
apt-get autoremove --purge mongodb  

Your code won't work; you need or instead of ||.

Try

'0' <= strg[:1] <= '9'

or

strg[:1] in '0123456789'

or, if you are really crazy about startswith,

strg.startswith(('0', '1', '2', '3', '4', '5', '6', '7', '8', '9'))

::: works only with lists, while ++ can be used with any traversable. In the current implementation (2.9.0), ++ falls back on ::: if the argument is also a List.

Welcome to Java! This Nodes are like a blocks, they must be assembled to do amazing things! In this particular case, your nodes can represent a list, a linked list, You can see an example here:

public class ItemLinkedList {
    private ItemInfoNode head;
    private ItemInfoNode tail;
    private int size = 0;

    public int getSize() {
        return size;
    }

    public void addBack(ItemInfo info) {
        size++;
        if (head == null) {
            head = new ItemInfoNode(info, null, null);
            tail = head;
        } else {
            ItemInfoNode node = new ItemInfoNode(info, null, tail);
            this.tail.next =node;
            this.tail = node;
        }
    }

    public void addFront(ItemInfo info) {
        size++;
        if (head == null) {
            head = new ItemInfoNode(info, null, null);
            tail = head;
        } else {
            ItemInfoNode node = new ItemInfoNode(info, head, null);
            this.head.prev = node;
            this.head = node;
        }
    }

    public ItemInfo removeBack() {
        ItemInfo result = null;
        if (head != null) {
            size--;
            result = tail.info;
            if (tail.prev != null) {
                tail.prev.next = null;
                tail = tail.prev;
            } else {
                head = null;
                tail = null;
            }
        }
        return result;
    }

    public ItemInfo removeFront() {
        ItemInfo result = null;
        if (head != null) {
            size--;
            result = head.info;
            if (head.next != null) {
                head.next.prev = null;
                head = head.next;
            } else {
                head = null;
                tail = null;
            }
        }
        return result;
    }

    public class ItemInfoNode {

        private ItemInfoNode next;
        private ItemInfoNode prev;
        private ItemInfo info;

        public ItemInfoNode(ItemInfo info, ItemInfoNode next, ItemInfoNode prev) {
            this.info = info;
            this.next = next;
            this.prev = prev;
        }

        public void setInfo(ItemInfo info) {
            this.info = info;
        }

        public void setNext(ItemInfoNode node) {
            next = node;
        }

        public void setPrev(ItemInfoNode node) {
            prev = node;
        }

        public ItemInfo getInfo() {
            return info;
        }

        public ItemInfoNode getNext() {
            return next;
        }

        public ItemInfoNode getPrev() {
            return prev;
        }
    }
}

EDIT:

Declare ItemInfo as this:

public class ItemInfo {
    private String name;
    private String rfdNumber;
    private double price;
    private String originalPosition;

    public ItemInfo(){
    }

    public ItemInfo(String name, String rfdNumber, double price, String originalPosition) {
        this.name = name;
        this.rfdNumber = rfdNumber;
        this.price = price;
        this.originalPosition = originalPosition;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getRfdNumber() {
        return rfdNumber;
    }

    public void setRfdNumber(String rfdNumber) {
        this.rfdNumber = rfdNumber;
    }

    public double getPrice() {
        return price;
    }

    public void setPrice(double price) {
        this.price = price;
    }

    public String getOriginalPosition() {
        return originalPosition;
    }

    public void setOriginalPosition(String originalPosition) {
        this.originalPosition = originalPosition;
    }
}

Then, You can use your nodes inside the linked list like this:

public static void main(String[] args) {
    ItemLinkedList list = new ItemLinkedList();
    for (int i = 1; i <= 10; i++) {
        list.addBack(new ItemInfo("name-"+i, "rfd"+i, i, String.valueOf(i)));

    }
    while (list.size() > 0){
        System.out.println(list.removeFront().getName());
    }
}

Late to the question, here, but: I maintain a class at this address: http://lacinato.com/cm/software/emailrelated/emailaddress

It is based on Les Hazlewood's class, but has numerous improvements and fixes a few bugs. Apache license.

I believe it is the most capable email parser in Java, and I have yet to see one more capable in any language, though there may be one out there. It's not a lexer-style parser, but uses some complicated java regex, and thus is not as efficient as it could be, but my company has parsed well over 10 billion real-world addresses with it: it's certainly usable in a high-performance situation. Maybe once a year it'll hit an address that causes a regex stack overflow (appropriately), but these are spam addresses which are hundreds or thousands of characters long with many many quotes and parenthesis and the like.

RFC 2822 and the related specs are really quite permissive in terms of email addresses, so a class like this is overkill for most uses. For example, the following is a legitimate address, according to spec, spaces and all:

"<bob \" (here) " < (hi there) "bob(the man)smith" (hi) @ (there) example.com (hello) > (again)

No mail server would allow that, but this class can parse it (and rewrite it to a usable form).

We found the existing Java email parser options to be insufficiently durable (meaning, all of them could not parse some valid addresses), so we created this class.

The code is well-documented and has a lot of easy-to-change options to allow or disallow certain email forms. It also provides a lot of methods to access certain parts of the address (left-hand side, right-hand side, personal names, comments, etc), to parse/validate mailbox-list headers, to parse/validate the return-path (which is unique among the headers), and so forth.

The code as written has a javamail dependency, but it's easy to remove if you don't want the minor functionality it provides.

You are facing a double-encoding issue.

¦ and • are absolutely equivalent to each other. Both refer to the Unicode character 'BULLET' (U+2022) and can exist side-by-side in HTML source code.

However, if that source-code is HTML-encoded again at some point, it will contain ¦ and •. The former is rendered unchanged, the latter will come out as "•" on the screen.

This is correct behavior under these circumstances. You need to find the point where the superfluous second HTML-encoding occurs and get rid of it.

I got this problem when insert wrong file address into .htaccess

php_value auto_prepend_file "/home/user/wrong/address/config.php"

So if you use auto_prepend_file check your file path. It called from .htaccess so PHP can't determine error file and line.

By 'return non-false', they mean to return any value which would not work out to boolean false. So you could return true, 1, 'non-false', or whatever else you can think up.

What is wrong with List<T>.Sort()?

Use $.on() to bind your chosen event to the input, don't use the shortcuts like $.keydown() etc because as of jQuery 1.7 $.on() is the preferred method to attach event handlers (see here: http://api.jquery.com/on/ and http://api.jquery.com/bind/).

$.keydown() is just a shortcut to $.bind('keydown'), and $.bind() is what $.on() replaces (among others).

To answer your question, as far as I'm aware, unless you need to fire an event on keydown specifically, the change event should do the trick for you.

$('element').on('change', function(){
    console.log('change');
});

To respond to the below comment, the javascript change event is documented here: https://developer.mozilla.org/en-US/docs/Web/Events/change

And here is a working example of the change event working on an input element, using jQuery: http://jsfiddle.net/p1m4xh08/

AArch64 is the 64-bit state introduced in the Armv8-A architecture (https://en.wikipedia.org/wiki/ARM_architecture#ARMv8-A). The 32-bit state which is backwards compatible with Armv7-A and previous 32-bit Arm architectures is referred to as AArch32. Therefore the GNU triplet for the 64-bit ISA is aarch64. The Linux kernel community chose to call their port of the kernel to this architecture arm64 rather than aarch64, so that's where some of the arm64 usage comes from.

As far as I know the Apple backend for aarch64 was called arm64 whereas the LLVM community-developed backend was called aarch64 (as it is the canonical name for the 64-bit ISA) and later the two were merged and the backend now is called aarch64.

So AArch64 and ARM64 refer to the same thing.

CR - ASCII code 13

LF - ASCII code 10.

Theoretically CR returns cursor to the first position (on the left). LF feeds one line moving cursor one line down. This is how in old days you controled printers and text-mode monitors. These characters are usually used to mark end of lines in text files. Different operating systems used different conventions. As you pointed out Windows uses CR/LF combination while pre-OSX Macs use just CR and so on.

In VS2010, right click the project in the Solution Explorer and select 'Add Deployable Dependencies'. Then check the MVC related check boxes in the following dialog.

This creates a '_bin_deployableAssemblies' folder in the project which contains all the .dll files mentioned in other answers. I believe these get copied to the bin folder when creating a deployment package.

The language spec mentions comparison operators' behaviors:

comparison operators

In any comparison, the first operand must be assignable to the type of the second operand, or vice versa.

Assignability

A value x is assignable to a variable of type T ("x is assignable to T") in any of these cases:

• x's type is identical to T.
• x's type V and T have identical underlying types and at least one of V or T is not a named type.
• T is an interface type and x implements T.
• x is a bidirectional channel value, T is a channel type, x's type V and T have identical element types, and at least one of V or T is not a named type.
• x is the predeclared identifier nil and T is a pointer, function, slice, map, channel, or interface type.
• x is an untyped constant representable by a value of type T.

The issue may be solved by running migrations.

1. python manage.py makemigrations
2. python manage.py migrate

perform the operations above whenever you make changes in models.py.

I found James Wald's answer the closest to my solution, except instead of "File->Import->General->Existing Projects into Workspace" (which did not work for me at all) I used "File->Import->Android->Existing Android Code Into Workspace". I am using Helios, maybe your version of Eclipse does not have this quirk.

It seems that Luiggi Mendoza and joey rohan both already answered this, but I think it can be clarified a little.

You can write it as a single if statement:

if (inventory.contains("bread") && !inventory.contains("water")) {
    // do something
}

For IE 7 & 8 (and other browsers without CSS3 support not including IE6) you can use the following to get the 2nd and 3rd children:

2nd Child:

td:first-child + td

3rd Child:

td:first-child + td + td

Then simply add another + td for each additional child you wish to select.

If you want to support IE6 that can be done too! You simply need to use a little javascript (jQuery in this example):

$(function() {
    $('td:first-child').addClass("firstChild");
    $(".table-class tr").each(function() {
        $(this).find('td:eq(1)').addClass("secondChild");
        $(this).find('td:eq(2)').addClass("thirdChild");
    });
});

Then in your css you simply use those class selectors to make whatever changes you like:

table td.firstChild { /*stuff here*/ }
table td.secondChild { /*stuff to apply to second td in each row*/ }

please don't try with the old cv module, use cv2:

import cv2

cv2.rectangle(img, (x1, y1), (x2, y2), (255,0,0), 2)


x1,y1 ------
|          |
|          |
|          |
--------x2,y2

[edit] to append the follow-up questions below:

cv2.imwrite("my.png",img)

cv2.imshow("lalala", img)
k = cv2.waitKey(0) # 0==wait forever

It is very inefficient to store all values in memory, so the objects are reused and loaded one at a time. See this other SO question for a good explanation. Summary:

[...] when looping through the Iterable value list, each Object instance is re-used, so it only keeps one instance around at a given time.

A string literal is delimited by quotation marks and is of type char* not char.

Example: "hello"

So when you compare a char to a char* you will get that same compiling error.

char c = 'c';
char *p = "hello";

if(c==p)//compiling error
{
} 

To fix use a char literal which is delimited by single quotes.

Example: 'c'

ORDER BY alters the order in which items are returned.

GROUP BY will aggregate records by the specified columns which allows you to perform aggregation functions on non-grouped columns (such as SUM, COUNT, AVG, etc).

TABLE:
ID NAME
1  Peter
2  John
3  Greg
4  Peter

SELECT *
FROM TABLE
ORDER BY NAME

= 
3 Greg
2 John
1 Peter
4 Peter

SELECT Count(ID), NAME
FROM TABLE
GROUP BY NAME

= 
1 Greg
1 John 
2 Peter

SELECT NAME
FROM TABLE
GROUP BY NAME
HAVING Count(ID) > 1

=
Peter

This method would be helpful :

String rightPart(String text,int length)
{
    if (text.length()<length) return text;
    String raw = "";
    for (int i = 1; i <= length; i++) {
        raw += text.toCharArray()[text.length()-i];
    }
    return new StringBuilder(raw).reverse().toString();
}

Is your server single-threaded? If so, what polling / multiplexing function are you using?

Using select() does not work beyond the hard-coded maximum file descriptor limit set at compile-time, which is hopeless (normally 256, or a few more).

poll() is better but you will end up with the scalability problem with a large number of FDs repopulating the set each time around the loop.

epoll() should work well up to some other limit which you hit.

10k connections should be easy enough to achieve. Use a recent(ish) 2.6 kernel.

How many client machines did you use? Are you sure you didn't hit a client-side limit?

A "C-program" is not supposed to be run. It is meant to be compiled into an "executable" program which then can be run from your terminal. You need a compiler for that.

Oh, and the answer to your last question ("Why?") is that the file you are trying to execute doesn't have the executable rights set (which a compiler usually does automatically with the binary, which let's infer that you were trying to run the source code as a script, hence the hint at compiling.)

In addition to the other options, in at least IntelliJ IDEA 2017 Ultimate, WebStorm 2020.2, and probably a ton of other versions, you can do it in a single shortcut.

Edit preferences, search for Select in Project View, and under Keymap, view the mapped shortcut or map one of your choice.

On the Mac, Ctrl + Option + L is not already used, and is the same shortcut as Visual Studio for Windows uses natively (Ctrl + Alt + L, so that could be a good choice.

In a Django template you can do:

<a href="{{ request.scheme }}://{{ request.META.HTTP_HOST }}{{ request.path }}?{{ request.GET.urlencode }}" >link</a>

As Stein says, you can use the prototype javascript library from http://www.prototypejs.org. Include the JS and it is very simple then, $('formName').serialize() will return what you want!

If you are doing it with Django, you can just pass the function with the context:

context = {
    'title':'My title',
    'str': str,
}
...
return render(request, 'index.html', context)

Now you will be able to use the str function in jinja2 template

There is a lovely vectorized solution that repeats only certain rows n-times each, possible for example by adding an ntimes column to your data frame:

  A B   C ntimes
1 j i 100      2
2 K P 101      4
3 Z Z 102      1

Method:

df <- data.frame(A=c("j","K","Z"), B=c("i","P","Z"), C=c(100,101,102), ntimes=c(2,4,1))
df <- as.data.frame(lapply(df, rep, df$ntimes))

Result:

  A B   C ntimes
1 Z Z 102      1
2 j i 100      2
3 j i 100      2
4 K P 101      4
5 K P 101      4
6 K P 101      4
7 K P 101      4

This is very similar to Josh O'Brien and Mark Miller's method:

df[rep(seq_len(nrow(df)), df$ntimes),]

However, that method appears quite a bit slower:

df <- data.frame(A=c("j","K","Z"), B=c("i","P","Z"), C=c(100,101,102), ntimes=c(2000,3000,4000))

microbenchmark::microbenchmark(
  df[rep(seq_len(nrow(df)), df$ntimes),],
  as.data.frame(lapply(df, rep, df$ntimes)),
  times = 10
)

Result:

Unit: microseconds
                                      expr      min       lq      mean   median       uq      max neval
   df[rep(seq_len(nrow(df)), df$ntimes), ] 3563.113 3586.873 3683.7790 3613.702 3657.063 4326.757    10
 as.data.frame(lapply(df, rep, df$ntimes))  625.552  654.638  676.4067  668.094  681.929  799.893    10

If you want to do anything else during the iteration, it may be nice to get both the index (which guarantees you being able to reference it, for example if you have a list of dicts) and the actual list item contents.

inlist = [{'field1':10, 'field2':20}, {'field1':30, 'field2':15}]    
for idx, i in enumerate(inlist):
    do some stuff with i['field1']
    if somecondition:
        xlist.append(idx)
for i in reversed(xlist): del inlist[i]

enumerate gives you access to the item and the index at once. reversed is so that the indices that you're going to later delete don't change on you.

Try to give the full path to your csv file

open('/users/gcameron/Desktop/map/data.csv')

The python process is looking for file in the directory it is running from.

Yes, there is. You can use the Arrays class from the java.util.* package. Then it's actually just one line of code.

List<String> list = Arrays.asList(array);

If you want the default colors of Android ICS, you just have to go to your Android SDK and look for this path: platforms\android-15\data\res\values\colors.xml.

I was not able to resolve this after several hours. Eventually I just did a select with the two tables joined, created an extract and created individual SQL update statements for the 500 rows in the table. Ugly but beats spending hours trying to get a query to work.

Ideally, you would create a method on the choice object that found itself in votes, or create a relationship between the models. A template tag that performed the dictionary lookup would work, too.

A more shorter solution: map and pass the arguments to Number:

var a = "1,2,3,4";_x000D_
var b = a.split(',');_x000D_
console.log(b);_x000D_
var c = b.map(Number);_x000D_
console.log(c);

if you return var-binary data from DB to display PDF on popup or browser means follow this code:-

View page:

@using (Html.BeginForm("DisplayPDF", "Scan", FormMethod.Post))
    {
        <a href="javascript:;" onclick="document.forms[0].submit();">View PDF</a>
    }

Scan controller:

public ActionResult DisplayPDF()
        {
            byte[] byteArray = GetPdfFromDB(4);
            MemoryStream pdfStream = new MemoryStream();
            pdfStream.Write(byteArray, 0, byteArray.Length);
            pdfStream.Position = 0;
            return new FileStreamResult(pdfStream, "application/pdf");
        }

        private byte[] GetPdfFromDB(int id)
        {
            #region
            byte[] bytes = { };
            string constr = System.Configuration.ConfigurationManager.ConnectionStrings["Connection"].ConnectionString;
            using (SqlConnection con = new SqlConnection(constr))
            {
                using (SqlCommand cmd = new SqlCommand())
                {
                    cmd.CommandText = "SELECT Scan_Pdf_File FROM PWF_InvoiceMain WHERE InvoiceID=@Id and Enabled = 1";
                    cmd.Parameters.AddWithValue("@Id", id);
                    cmd.Connection = con;
                    con.Open();
                    using (SqlDataReader sdr = cmd.ExecuteReader())
                    {
                        if (sdr.HasRows == true)
                        {
                            sdr.Read();
                            bytes = (byte[])sdr["Scan_Pdf_File"];
                        }
                    }
                    con.Close();
                }
            }

            return bytes;
            #endregion
        }

You could write an extension method (for what it's worth):

public static string EmptyNull(this string str)
{
    return str ?? "";
}

Now this works safely:

string str = null;
string upper = str.EmptyNull().ToUpper();

To resolve this follow following steps:

1. Open the entries file located in .svn directory where you are getting the error.
2. Find the entry for the file giving error and replace the expected value with actual value in error.
3. Now synchronize and try to update.

If it still does not work. Try these. Its just a workaround though:

1. Delete the file from your system.
2. Delete the entry of the file from entries file. (Starting from the name of the file till the special characters).
3. Now Synchronize and update the file.

This will get latest version of file from repository and all conflicts will be resolved.

According to caniuse.com:

• 97.72% of global users natively support WebSockets
• 96.31% of global users natively support Server-sent events

You can use a client-only polyfill to extend support of SSE to many other browsers. This is less likely with WebSockets. Some EventSource polyfills:

• EventSource by Remy Sharp with no other library dependencies (IE7+)
• jQuery.EventSource by Rick Waldron
• EventSource by Yaffle (replaces native implementation, normalising behaviour across browsers)

If you need to support all the browsers, consider using a library like web-socket-js, SignalR or socket.io which support multiple transports such as WebSockets, SSE, Forever Frame and AJAX long polling. These often require modifications to the server side as well.

Learn more about SSE from:

• HTML5 Rocks article
• The W3C spec (published version, editor's draft)

Other differences:

• WebSockets supports arbitrary binary data, SSE only uses UTF-8
