You cannot use VBA (Interior.ColorIndex) in a formula which is why you receive the error.

It is not possible to do this without VBA.

Function YellowIt(rng As Range) As Boolean
    If rng.Interior.ColorIndex = 6 Then
        YellowIt = True
    Else
        YellowIt = False
    End If
End Function

However, I do not recommend this: it is not how user-defined VBA functions (UDFs) are intended to be used. They should reflect the behaviour of Excel functions, which cannot read the colour-formatting of a cell. (This function may not work in a future version of Excel.)

It is far better that you base a formula on the original condition (decision) that makes the cell yellow in the first place. Or, alternatively, run a Sub procedure to fill in the True or False values (although, of course, these values will no longer be linked to the original cell's formatting).

Using Query parameter

<a href="edit.jsp?userId=${user.id}" />  

Using Hidden variable .

<form method="post" action="update.jsp">  
...  
   <input type="hidden" name="userId" value="${user.id}">  

you can send Using Session object.

   session.setAttribute("userId", userid);

These values will now be available from any jsp as long as your session is still active.

   int userid = session.getAttribute("userId"); 

I had the issue that I was passing a URL into a library which was calling url.openConnection(); I adapted jon-daniel's answer,

public class TrustHostUrlStreamHandler extends URLStreamHandler {

    private static final Logger LOG = LoggerFactory.getLogger(TrustHostUrlStreamHandler.class);

    @Override
    protected URLConnection openConnection(final URL url) throws IOException {

        final URLConnection urlConnection = new URL(url.getProtocol(), url.getHost(), url.getPort(), url.getFile()).openConnection();

        // adapated from
        // https://stackoverflow.com/questions/2893819/accept-servers-self-signed-ssl-certificate-in-java-client
        if (urlConnection instanceof HttpsURLConnection) {
            final HttpsURLConnection conHttps = (HttpsURLConnection) urlConnection;

            try {
                // Set up a Trust all manager
                final TrustManager[] trustAllCerts = new TrustManager[] { new X509TrustManager() {

                    @Override
                    public java.security.cert.X509Certificate[] getAcceptedIssuers() {
                        return null;
                    }

                    @Override
                    public void checkClientTrusted(final java.security.cert.X509Certificate[] certs, final String authType) {
                    }

                    @Override
                    public void checkServerTrusted(final java.security.cert.X509Certificate[] certs, final String authType) {
                    }
                } };

                // Get a new SSL context
                final SSLContext sc = SSLContext.getInstance("TLSv1.2");
                sc.init(null, trustAllCerts, new java.security.SecureRandom());
                // Set our connection to use this SSL context, with the "Trust all" manager in place.
                conHttps.setSSLSocketFactory(sc.getSocketFactory());
                // Also force it to trust all hosts
                final HostnameVerifier allHostsValid = new HostnameVerifier() {
                    @Override
                    public boolean verify(final String hostname, final SSLSession session) {
                        return true;
                    }
                };

                // and set the hostname verifier.
                conHttps.setHostnameVerifier(allHostsValid);

            } catch (final NoSuchAlgorithmException e) {
                LOG.warn("Failed to override URLConnection.", e);
            } catch (final KeyManagementException e) {
                LOG.warn("Failed to override URLConnection.", e);
            }

        } else {
            LOG.warn("Failed to override URLConnection. Incorrect type: {}", urlConnection.getClass().getName());
        }

        return urlConnection;
    }

}

Using this class it is possible to create a new URL with:

trustedUrl = new URL(new URL(originalUrl), "", new TrustHostUrlStreamHandler());
trustedUrl.openConnection();

This has the advantage that it is localized and not replacing the default URL.openConnection.

In my case, I had a condition when the user click the "a" element. The condition was:

If other section had more than ten items, then the user should be not redirected to other page.

If other section had less than ten items, then the user should be redirected to other page.

The functionality of the "a" elements depends of the other component. The code within click event is the follow:

var elementsOtherSection = document.querySelectorAll("#vehicle-item").length;
if (elementsOtherSection> 10){
     return true;
}else{
     event.preventDefault();
     return false;
}

Here is a real world example:

String hallostring = "hallo";
String asubstring = hallostring.substring(0, 1); 

In the example asubstring would return: h

Add a helper class:

public static class Redirector {
        public static void RedirectTo(this Controller ct, string action) {
            UrlHelper urlHelper = new UrlHelper(ct.ControllerContext.RequestContext);

            ct.Response.Headers.Add("AjaxRedirectURL", urlHelper.Action(action));
        }

        public static void RedirectTo(this Controller ct, string action, string controller) {
            UrlHelper urlHelper = new UrlHelper(ct.ControllerContext.RequestContext);

            ct.Response.Headers.Add("AjaxRedirectURL", urlHelper.Action(action, controller));
        }

        public static void RedirectTo(this Controller ct, string action, string controller, object routeValues) {
            UrlHelper urlHelper = new UrlHelper(ct.ControllerContext.RequestContext);

            ct.Response.Headers.Add("AjaxRedirectURL", urlHelper.Action(action, controller, routeValues));
        }
    }

Then call in your action:

this.RedirectTo("Index", "Cement");

Add javascript code to any global javascript included file or layout file to intercept all ajax requests:

<script type="text/javascript">_x000D_
  $(function() {_x000D_
    $(document).ajaxComplete(function (event, xhr, settings) {_x000D_
            var urlHeader = xhr.getResponseHeader('AjaxRedirectURL');_x000D_
_x000D_
            if (urlHeader != null && urlHeader !== undefined) {_x000D_
                window.location = xhr.getResponseHeader('AjaxRedirectURL');_x000D_
            }_x000D_
        });_x000D_
  });_x000D_
</script>

Add this code below. Once turns it off, releases the filter. Second time turns it back on without filters.

Not very elegant, but served my purpose.

ActiveSheet.ListObjects("MyTable").Range.AutoFilter

'then call it again?
ActiveSheet.ListObjects("MyTable").Range.AutoFilter

The place where each can cause you problems is that it's a true, non-scoped iterator. By way of example:

while ( my ($key,$val) = each %a_hash ) {
    print "$key => $val\n";
    last if $val; #exits loop when $val is true
}

# but "each" hasn't reset!!
while ( my ($key,$val) = each %a_hash ) {
    # continues where the last loop left off
    print "$key => $val\n";
}

If you need to be sure that each gets all the keys and values, you need to make sure you use keys or values first (as that resets the iterator). See the documentation for each.

Step 1: Hook your HTML number input box to an onchange event

myHTMLNumberInput.onchange = setTwoNumberDecimal;

or in the HTML code

<input type="number" onchange="setTwoNumberDecimal" min="0" max="10" step="0.25" value="0.00" />

Step 2: Write the setTwoDecimalPlace method

function setTwoNumberDecimal(event) {
    this.value = parseFloat(this.value).toFixed(2);
}

You can alter the number of decimal places by varying the value passed into the toFixed() method. See MDN docs.

toFixed(2); // 2 decimal places
toFixed(4); // 4 decimal places
toFixed(0); // integer

Here is a summary.

1. escape() will not encode @ * _ + - . /

   Do not use it.

2. encodeURI() will not encode A-Z a-z 0-9 ; , / ? : @ & = + $ - _ . ! ~ * ' ( ) #

   Use it when your input is a complete URL like 'https://searchexample.com/search?q=wiki'

3. encodeURIComponent() will not encode A-Z a-z 0-9 - _ . ! ~ * ' ( ) Use it when your input is part of a complete URL e.g const queryStr = encodeURIComponent(someString)

I found the following removed the indent and the margin from both the left AND right sides, but allowed the bullets to remain left-justified below the text above it. Add this to your css file:

ul.noindent {
    margin-left: 5px;
    margin-right: 0px;
    padding-left: 10px;
    padding-right: 0px;
}

To use it in your html file add class="noindent" to the UL tag. I've tested w/FF 14 and IE 9.

I have no idea why browsers default to the indents, but I haven't really had a reason for changing them that often.

When you use the dir([object]) built-in function, you can get the __sizeof__ of the built-in function.

>>> a = -1
>>> a.__sizeof__()
24

A Nuget solved my problem:Geocoding.Google 4.0.0. Install it so not necessary to write extra classes etc.

https://www.nuget.org/packages/Geocoding.Google/

The word "read" is vague, but here is an example which reads a jpeg file using the Image class, and prints information about it.

from PIL import Image
jpgfile = Image.open("picture.jpg")

print(jpgfile.bits, jpgfile.size, jpgfile.format)

In addition to what @ckal suggested, it is critical to give each renamed Configuration.cs its own namespace. If you do not, EF will attempt to apply migrations to the wrong context.

Here are the specific steps that work well for me.

If Migrations are messed up and you want to create a new "baseline":

1. Delete any existing .cs files in the Migrations folder
2. In SSMS, delete the __MigrationHistory system table.

Creating the initial migration:

1. In Package Manager Console:

   Enable-Migrations -EnableAutomaticMigrations -ContextTypeName
   NamespaceOfContext.ContextA -ProjectName ProjectContextIsInIfNotMainOne
   -StartupProjectName NameOfMainProject  -ConnectionStringName ContextA
   

2. In Solution Explorer: Rename Migrations.Configuration.cs to Migrations.ConfigurationA.cs. This should automatically rename the constructor if using Visual Studio. Make sure it does. Edit ConfigurationA.cs: Change the namespace to NamespaceOfContext.Migrations.MigrationsA

3. Enable-Migrations -EnableAutomaticMigrations -ContextTypeName
   NamespaceOfContext.ContextB -ProjectName ProjectContextIsInIfNotMainOne
   -StartupProjectName NameOfMainProject  -ConnectionStringName ContextB
   

4. In Solution Explorer: Rename Migrations.Configuration.cs to Migrations.ConfigurationB.cs. Again, make sure the constructor is also renamed appropriately. Edit ConfigurationB.cs: Change the namespace to NamespaceOfContext.Migrations.MigrationsB

5. add-migration InitialBSchema -IgnoreChanges -ConfigurationTypeName
   ConfigurationB -ProjectName ProjectContextIsInIfNotMainOne
   -StartupProjectName NameOfMainProject  -ConnectionStringName ContextB 
   

6. Update-Database -ConfigurationTypeName ConfigurationB -ProjectName
   ProjectContextIsInIfNotMainOne -StartupProjectName NameOfMainProject
   -ConnectionStringName ContextB
   

7. add-migration InitialSurveySchema -IgnoreChanges -ConfigurationTypeName
   ConfigurationA -ProjectName ProjectContextIsInIfNotMainOne -StartupProjectName
   NameOfMainProject  -ConnectionStringName ContextA 
   

8. Update-Database -ConfigurationTypeName ConfigurationA -ProjectName
   ProjectContextIsInIfNotMainOne -StartupProjectName NameOfMainProject
   -ConnectionStringName ContextA
   

Steps to create migration scripts in Package Manager Console:

1. Run command

   Add-Migration MYMIGRATION -ConfigurationTypeName ConfigurationA -ProjectName
   ProjectContextIsInIfNotMainOne -StartupProjectName NameOfMainProject
   -ConnectionStringName ContextA
   

   or -

   Add-Migration MYMIGRATION -ConfigurationTypeName ConfigurationB -ProjectName
   ProjectContextIsInIfNotMainOne -StartupProjectName NameOfMainProject
   -ConnectionStringName ContextB
   

   It is OK to re-run this command until changes are applied to the DB.

2. Either run the scripts against the desired local database, or run Update-Database without -Script to apply locally:

   Update-Database -ConfigurationTypeName ConfigurationA -ProjectName
   ProjectContextIsInIfNotMainOne -StartupProjectName NameOfMainProject
   -ConnectionStringName ContextA
   

   or -

   Update-Database -ConfigurationTypeName ConfigurationB -ProjectName
   ProjectContextIsInIfNotMainOne -StartupProjectName NameOfMainProject
   -ConnectionStringName ContextB
   

You can use geolocator.js for easily getting timezone and more...

It uses Google APIs that require a key. So, first you configure geolocator:

geolocator.config({
    language: "en",
    google: {
        version: "3",
        key: "YOUR-GOOGLE-API-KEY"
    }
});

Get TimeZone if you have the coordinates:

geolocator.getTimeZone(options, function (err, timezone) {
    console.log(err || timezone);
});

Example output:

{
    id: "Europe/Paris",
    name: "Central European Standard Time",
    abbr: "CEST",
    dstOffset: 0,
    rawOffset: 3600,
    timestamp: 1455733120
}

Locate then get TimeZone and more

If you don't have the coordinates, you can locate the user position first.

Example below will first try HTML5 Geolocation API to get the coordinates. If it fails or rejected, it will get the coordinates via Geo-IP look-up. Finally, it will get the timezone and more...

var options = {
    enableHighAccuracy: true,
    timeout: 6000,
    maximumAge: 0,
    desiredAccuracy: 30,
    fallbackToIP: true, // if HTML5 fails or rejected
    addressLookup: true, // this will get full address information
    timezone: true,
    map: "my-map" // this will even create a map for you
};
geolocator.locate(options, function (err, location) {
    console.log(err || location);
});

Example output:

{
    coords: {
        latitude: 37.4224764,
        longitude: -122.0842499,
        accuracy: 30,
        altitude: null,
        altitudeAccuracy: null,
        heading: null,
        speed: null
    },
    address: {
        commonName: "",
        street: "Amphitheatre Pkwy",
        route: "Amphitheatre Pkwy",
        streetNumber: "1600",
        neighborhood: "",
        town: "",
        city: "Mountain View",
        region: "Santa Clara County",
        state: "California",
        stateCode: "CA",
        postalCode: "94043",
        country: "United States",
        countryCode: "US"
    },
    formattedAddress: "1600 Amphitheatre Parkway, Mountain View, CA 94043, USA",
    type: "ROOFTOP",
    placeId: "ChIJ2eUgeAK6j4ARbn5u_wAGqWA",
    timezone: {
        id: "America/Los_Angeles",
        name: "Pacific Standard Time",
        abbr: "PST",
        dstOffset: 0,
        rawOffset: -28800
    },
    flag: "//cdnjs.cloudflare.com/ajax/libs/flag-icon-css/2.3.1/flags/4x3/us.svg",
    map: {
        element: HTMLElement,
        instance: Object, // google.maps.Map
        marker: Object, // google.maps.Marker
        infoWindow: Object, // google.maps.InfoWindow
        options: Object // map options
    },
    timestamp: 1456795956380
}

There is nothing wrong with count() here, "trends" is the only key that is being counted in this case, you can try doing:

count($obj->trends);

Or:

count($obj->trends['2009-08-21 11:05']);

Or maybe even doing:

count($obj, COUNT_RECURSIVE);

Sure:

var query = grades.GroupBy(student => student.Name)
                  .Select(group => 
                        new { Name = group.Key,
                              Students = group.OrderByDescending(x => x.Grade) })
                  .OrderBy(group => group.Students.First().Grade);

Note that you can get away with just taking the first grade within each group after ordering, because you already know the first entry will be have the highest grade.

Then you could display them with:

foreach (var group in query)
{
    Console.WriteLine("Group: {0}", group.Name);
    foreach (var student in group.Students)
    {
        Console.WriteLine("  {0}", student.Grade);
    }
}

FileReader reads from files on the file system.

Perhaps you intended to use something like this to load a file from the class path

// this will look in src/main/resources before building and myjar.jar! after building.
InputStream is = MyClass.class.getClassloader()
                     .getResourceAsStream("config.txt");

Or you could extract the file from the jar before reading it.

Try adding a function inside the click() method.

$('#gift-close').click(function(){
  //do something here
});

It worked for me with a function assigned inside the click() method rather than keeping it empty.

First, the ++ operator takes precedence over the * operator, and the () operators take precedence over everything else.

Second, the ++number operator is the same as the number++ operator if you're not assigning them to anything. The difference is number++ returns number and then increments number, and ++number increments first and then returns it.

Third, by increasing the value of a pointer, you're incrementing it by the sizeof its contents, that is you're incrementing it as if you were iterating in an array.

So, to sum it all up:

ptr++;    // Pointer moves to the next int position (as if it was an array)
++ptr;    // Pointer moves to the next int position (as if it was an array)
++*ptr;   // The value of ptr is incremented
++(*ptr); // The value of ptr is incremented
++*(ptr); // The value of ptr is incremented
*ptr++;   // Pointer moves to the next int position (as if it was an array). But returns the old content
(*ptr)++; // The value of ptr is incremented
*(ptr)++; // Pointer moves to the next int position (as if it was an array). But returns the old content
*++ptr;   // Pointer moves to the next int position, and then get's accessed, with your code, segfault
*(++ptr); // Pointer moves to the next int position, and then get's accessed, with your code, segfault

As there are a lot of cases in here, I might have made some mistake, please correct me if I'm wrong.

EDIT:

So I was wrong, the precedence is a little more complicated than what I wrote, view it here: http://en.cppreference.com/w/cpp/language/operator_precedence

r := strings(byteData)

This also works to turn []byte into io.Reader

Sorting, skipping and so on can be pretty slow depending on the size of your collection.

A better performance would be achieved if you have your collection indexed by some criteria; and then you could use min() cursor:

First, index your collection with db.collectionName.setIndex( yourIndex ) You can use ascending or descending order, which is cool, because you want always the "N last items"... so if you index by descending order it is the same as getting the "first N items".

Then you find the first item of your collection and use its index field values as the min criteria in a search like:

db.collectionName.find().min(minCriteria).hint(yourIndex).limit(N)

Here's the reference for min() cursor: https://docs.mongodb.com/manual/reference/method/cursor.min/

Do you have a typo in your .h? I once came across this error when i had the method properly called in my main, but with a typo in the .h/.cpp (a "g" vs a "q" in the method name, which made it kinda difficult to spot). It falls under the "copy/paste error" category.

You can try this:

Calendar sDate = Calendar.getInstance();
Calendar eDate = Calendar.getInstance();
sDate.setTime(startDate.getTime());
eDate.setTime(endDate.getTime());
int difInMonths = sDate.get(Calendar.MONTH) - eDate.get(Calendar.MONTH);

I think this should work. I used something similar for my project and it worked for what I needed (year diff). You get a Calendar from a Date and just get the month's diff.

Maybe:

crimefile = open(fileName, 'r')
yourResult = [line.split(',') for line in crimefile.readlines()]

For image tag you can use this type of style, it worked for me:

imageStyle: {
    width: Dimensions.get('window').width - 23,
    resizeMode: "contain",
    height: 211,
 },

What It Is

This is an arrow function. Arrow functions are a short syntax, introduced by ECMAscript 6, that can be used similarly to the way you would use function expressions. In other words, you can often use them in place of expressions like function (foo) {...}. But they have some important differences. For example, they do not bind their own values of this (see below for discussion).

Arrow functions are part of the ECMAscript 6 specification. They are not yet supported in all browsers, but they are partially or fully supported in Node v. 4.0+ and in most modern browsers in use as of 2018. (I’ve included a partial list of supporting browsers below).

You can read more in the Mozilla documentation on arrow functions.

From the Mozilla documentation:

An arrow function expression (also known as fat arrow function) has a shorter syntax compared to function expressions and lexically binds the this value (does not bind its own this, arguments, super, or new.target). Arrow functions are always anonymous. These function expressions are best suited for non-method functions and they can not be used as constructors.

A Note on How this Works in Arrow Functions

One of the most handy features of an arrow function is buried in the text above:

An arrow function... lexically binds the this value (does not bind its own this...)

What this means in simpler terms is that the arrow function retains the this value from its context and does not have its own this. A traditional function may bind its own this value, depending on how it is defined and called. This can require lots of gymnastics like self = this;, etc., to access or manipulate this from one function inside another function. For more info on this topic, see the explanation and examples in the Mozilla documentation.

Example Code

Example (also from the docs):

var a = [
  "We're up all night 'til the sun",
  "We're up all night to get some",
  "We're up all night for good fun",
  "We're up all night to get lucky"
];

// These two assignments are equivalent:

// Old-school:
var a2 = a.map(function(s){ return s.length });

// ECMAscript 6 using arrow functions
var a3 = a.map( s => s.length );

// both a2 and a3 will be equal to [31, 30, 31, 31]

Notes on Compatibility

You can use arrow functions in Node, but browser support is spotty.

Browser support for this functionality has improved quite a bit, but it still is not widespread enough for most browser-based usages. As of December 12, 2017, it is supported in current versions of:

• Chrome (v. 45+)
• Firefox (v. 22+)
• Edge (v. 12+)
• Opera (v. 32+)
• Android Browser (v. 47+)
• Opera Mobile (v. 33+)
• Chrome for Android (v. 47+)
• Firefox for Android (v. 44+)
• Safari (v. 10+)
• iOS Safari (v. 10.2+)
• Samsung Internet (v. 5+)
• Baidu Browser (v. 7.12+)

Not supported in:

• IE (through v. 11)
• Opera Mini (through v. 8.0)
• Blackberry Browser (through v. 10)
• IE Mobile (through v. 11)
• UC Browser for Android (through v. 11.4)
• QQ (through v. 1.2)

I learned of this neat trick in an internship interview. The original question is how do you ensure the height of each top component in three columns have the same height that shows all the content available. Basically create a child component that is invisible that renders the maximum possible height.

<div class="parent">
    <div class="assert-height invisible">
        <!-- content -->
    </div>
    <div class="shown">
        <!-- content -->
    </div>
</div>

No.

Not a documented 100% supported way. There is an approach sometimes used for calculating running totals called "quirky update" that suggests that it might update in order of clustered index if certain conditions are met but as far as I know this relies completely on empirical observation rather than any guarantee.

But what version of SQL Server are you on? If SQL2005+ you might be able to do something with row_number and a CTE (You can update the CTE)

With cte As
(
SELECT id,Number,
ROW_NUMBER() OVER (ORDER BY id DESC) AS RN
FROM Test
)
UPDATE cte SET Number=RN

echo "test" | mailx -r [email protected] -s 'test' [email protected]

It works in OpenBSD.

Try to avoid formatting in your query. You should return your data in a raw format and let the receiving application (e.g. a reporting service or end user app) do the formatting, i.e. rounding and so on.

Formatting the data in the server makes it harder (or even impossible) for you to further process your data. You usually want export the table or do some aggregation as well, like sum, average etc. As the numbers arrive as strings (varchar), there is usually no easy way to further process them. Some report designers will even refuse to offer the option to aggregate these 'numbers'.

Also, the end user will see the country specific formatting of the server instead of his own PC.

Also, consider rounding problems. If you round the values in the server and then still do some calculations (supposing the client is able to revert the number-strings back to a number), you will end up getting wrong results.

As per Prerak K's update comment (since deleted):

I guess I have not presented the question properly.

Situation is this: I want to load data into a global variable based on the value of a control. I don't want to change the value of a control from the child thread. I'm not going to do it ever from a child thread.

So only accessing the value so that corresponding data can be fetched from the database.

The solution you want then should look like:

UserContrl1_LOadDataMethod()
{
    string name = "";
    if(textbox1.InvokeRequired)
    {
        textbox1.Invoke(new MethodInvoker(delegate { name = textbox1.text; }));
    }
    if(name == "MyName")
    {
        // do whatever
    }
}

Do your serious processing in the separate thread before you attempt to switch back to the control's thread. For example:

UserContrl1_LOadDataMethod()
{
    if(textbox1.text=="MyName") //<<======Now it wont give exception**
    {
        //Load data correspondin to "MyName"
        //Populate a globale variable List<string> which will be
        //bound to grid at some later stage
        if(InvokeRequired)
        {
            // after we've done all the processing, 
            this.Invoke(new MethodInvoker(delegate {
                // load the control with the appropriate data
            }));
            return;
        }
    }
}

AngularJS has some methods called JQlite so we can use it. see link

Select the element in DOM is

angular.element( document.querySelector( '#div1' ) );

add the class like .addClass('alpha');

So finally

var myEl = angular.element( document.querySelector( '#div1' ) );
myEl.addClass('alpha');

To get make to actually ignore errors on a single line, you can simply suffix it with ; true, setting the return value to 0. For example:

rm .lambda .lambda_t .activity .activity_t_lambda 2>/dev/null; true

This will redirect stderr output to null, and follow the command with true (which always returns 0, causing make to believe the command succeeded regardless of what actually happened), allowing program flow to continue.

The how-to-prevent-xss has been asked several times. You will find a lot of information in StackOverflow. Also, OWASP website has an XSS prevention cheat sheet that you should go through.

On the libraries to use, OWASP's ESAPI library has a java flavour. You should try that out. Besides that, every framework that you use has some protection against XSS. Again, OWASP website has information on most popular frameworks, so I would recommend going through their site.

They do this in kids pre-school all the time. When they are outdoors on a road or something similar, each kid is asked to hold couple of other kids hand. Each kid knows whose hand he or she is supposed to hold. That's how they cross the road. I think this is a classic example of a doubly-linked list.

This method will give perfect height

-(float) getHeightForText:(NSString*) text withFont:(UIFont*) font andWidth:(float) width{
CGSize constraint = CGSizeMake(width , 20000.0f);
CGSize title_size;
float totalHeight;


title_size = [text boundingRectWithSize:constraint
                                options:NSStringDrawingUsesLineFragmentOrigin
                             attributes:@{ NSFontAttributeName : font }
                                context:nil].size;

totalHeight = ceil(title_size.height);

CGFloat height = MAX(totalHeight, 40.0f);
return height;
}

If you are on .NET 4.0 use a Tuple:

lookup = new Dictionary<Tuple<TypeA, TypeB, TypeC>, string>();

If not you can define a Tuple and use that as the key. The Tuple needs to override GetHashCode, Equals and IEquatable:

struct Tuple<T, U, W> : IEquatable<Tuple<T,U,W>>
{
    readonly T first;
    readonly U second;
    readonly W third;

    public Tuple(T first, U second, W third)
    {
        this.first = first;
        this.second = second;
        this.third = third;
    }

    public T First { get { return first; } }
    public U Second { get { return second; } }
    public W Third { get { return third; } }

    public override int GetHashCode()
    {
        return first.GetHashCode() ^ second.GetHashCode() ^ third.GetHashCode();
    }

    public override bool Equals(object obj)
    {
        if (obj == null || GetType() != obj.GetType())
        {
            return false;
        }
        return Equals((Tuple<T, U, W>)obj);
    }

    public bool Equals(Tuple<T, U, W> other)
    {
        return other.first.Equals(first) && other.second.Equals(second) && other.third.Equals(third);
    }
}

One is an array of arrays, and one is a 2d array. The former can be jagged, the latter is uniform.

That is, a double[][] can validly be:

double[][] x = new double[5][];

x[0] = new double[10];
x[1] = new double[5];
x[2] = new double[3];
x[3] = new double[100];
x[4] = new double[1];

Because each entry in the array is a reference to an array of double. With a jagged array, you can do an assignment to an array like you want in your second example:

x[0] = new double[13];

On the second item, because it is a uniform 2d array, you can't assign a 1d array to a row or column, because you must index both the row and column, which gets you down to a single double:

double[,] ServicePoint = new double[10,9];

ServicePoint[0]... // <-- meaningless, a 2d array can't use just one index.

UPDATE:

To clarify based on your question, the reason your #1 had a syntax error is because you had this:

double[][] ServicePoint = new double[10][9];

And you can't specify the second index at the time of construction. The key is that ServicePoint is not a 2d array, but an 1d array (of arrays) and thus since you are creating a 1d array (of arrays), you specify only one index:

double[][] ServicePoint = new double[10][];

Then, when you create each item in the array, each of those are also arrays, so then you can specify their dimensions (which can be different, hence the term jagged array):

ServicePoint[0] = new double[13];
ServicePoint[1] = new double[20];

Hope that helps!

In C++ it is done like this:

#define LOCAL_PI 3.1415926535897932385 

double ToRadians(double degrees) 
{
  double radians = degrees * LOCAL_PI / 180;
  return radians;
}

double DirectDistance(double lat1, double lng1, double lat2, double lng2) 
{
  double earthRadius = 3958.75;
  double dLat = ToRadians(lat2-lat1);
  double dLng = ToRadians(lng2-lng1);
  double a = sin(dLat/2) * sin(dLat/2) + 
             cos(ToRadians(lat1)) * cos(ToRadians(lat2)) * 
             sin(dLng/2) * sin(dLng/2);
  double c = 2 * atan2(sqrt(a), sqrt(1-a));
  double dist = earthRadius * c;
  double meterConversion = 1609.00;
  return dist * meterConversion;
}

All of the above answers were perfectly clear and complete, but just for the record I'd like to confirm that the meaning of * and ** in python has absolutely no similarity with the meaning of similar-looking operators in C.

They are called the argument-unpacking and keyword-argument-unpacking operators.

if($(".myClass")[0] != undefined){
  // it exists
}else{
  // does not exist
}

This answers is for command needed for undoing local changes which are in multiple specific files in same or multiple folders (or directories). This answers specifically addresses question where a user has more than one file but the user doesn't want to undo all local changes:

if you have one or more files you could apply the same command (git checkout -- file ) to each of those files by listing each of their location separated by space as in:

git checkout -- name1/name2/fileOne.ext nameA/subFolder/fileTwo.ext

mind the space above between name1/name2/fileOne.ext nameA/subFolder/fileTwo.ext

For multiple files in the same folder:

If you happen to need to discard changes for all of the files in a certain directory, use the git checkout as follows:

git checkout -- name1/name2/*

The asterisk in the above does the trick of undoing all files at that location under name1/name2.

And, similarly the following can undo changes in all files for multiple folders:

git checkout -- name1/name2/* nameA/subFolder/*

again mind the space between name1/name2/* nameA/subFolder/* in the above.

Note: name1, name2, nameA, subFolder - all of these example folder names indicate the folder or package where the file(s) in question may be residing.

You forgot to add the global operator. Use this:

var s = "04.07.2012";_x000D_
alert(s.replace(new RegExp("[0-9]","g"), "X")); 

Denis's answer made me think to another solution using JsonObjects,

a header property checker:

Predicate<object> hasHeader = jsonObject =>
                                 ((JObject)jsonObject).OfType<JProperty>()
                                     .Any(prop => prop.Name == "header");

or maybe better:

Predicate<object> hasHeader = jsonObject =>
                                 ((JObject)jsonObject).Property("header") != null;

for example:

dynamic json = JsonConvert.DeserializeObject(data);
string header = hasHeader(json) ? json.header : null;

Best way to rounding off a floating value by "n" decimal places, is as following with in O(1) time:-

We have to round off the value by 3 places i.e. n=3.So,

float a=47.8732355;
printf("%.3f",a);

Use %03d in the format specifier for the integer. The 0 means that the number will be zero-filled if it is less than three (in this case) digits.

See the Formatter docs for other modifiers.

Dividing the app into blueprints is a great idea. However, if this isn't enough, and if you want to then divide the Blueprint itself into multiple py files, this is also possible using the regular Python module import system, and then looping through all the routes that get imported from the other files.

I created a Gist with the code for doing this:

https://gist.github.com/Jaza/61f879f577bc9d06029e

As far as I'm aware, this is the only feasible way to divide up a Blueprint at the moment. It's not possible to create "sub-blueprints" in Flask, although there's an issue open with a lot of discussion about this:

https://github.com/mitsuhiko/flask/issues/593

Also, even if it were possible (and it's probably do-able using some of the snippets from that issue thread), sub-blueprints may be too restrictive for your use case anyway - e.g. if you don't want all the routes in a sub-module to have the same URL sub-prefix.

You can restart your current activity like this:

Fragment :

activity?.recreate()

Activity :

recreate()

You almost had it with Not. It should be:

if (-Not (Test-Path C:\Code)) {
    write "it doesn't exist!"
} 

You can also use !: if (!(Test-Path C:\Code)){}

Just for fun, you could also use bitwise exclusive or, though it's not the most readable/understandable method.

if ((test-path C:\code) -bxor 1) {write "it doesn't exist!"}

I had a similar need. This worked for me:

find ../../ \( -iname 'tmp' -o -iname 'vendor' \) -prune -o \( -iname '*.*rb' -o -iname '*.rjs' \) -print

As recommended in a comment, I used the "Google Maps Platform API Checker" Chrome add-in to identify and resolve the issue.

Essentially, this add-in directed me to here where I was able to sign in to Google and create a free API key.

Afterwards, I updated my JavaScript and it immediately resolved this issue.

Old JavaScript: ...script src="https://maps.googleapis.com/maps/api/js?v=3" ...

Updated Javascript:...script src="https://maps.googleapis.com/maps/api/js?key=*****GOOGLE API KEY******&v=3" ...

The add-in then validated the JS API call. Hope this helps someone resolve the issue quickly!

exponent is a 1D array. This means that exponent[0] is a scalar, and exponent[0][i] is trying to access it as if it were an array.

Did you mean to say:

L = identity(len(l))
for i in xrange(len(l)):
    L[i][i] = exponent[i]

or even

L = diag(exponent)

?

You are using a relative path, which means that the program looks for the file in the working directory. The error is telling you that there is no file of that name in the working directory.

Try using the exact, or absolute, path.

The syntax to store the command output into a variable is var=$(command).

So you can directly do:

result=$(ls -l | grep -c "rahul.*patle")

And the variable $result will contain the number of matches.

A quick-and-dirty solution is just by generating a new list.

Check your Pattern (DD-MMM-YYYY) and the input for the parse("29-11-2018") method. Input to the parse method should follow : DD-MMM-YYYY i,e. 21-AUG-2019

In My Code:

String pattern = "DD-MMM-YYYY";
SimpleDateFormat simpleDateFormat = new SimpleDateFormat(pattern);

    try {
        startDate = simpleDateFormat.parse("29-11-2018");// here no pattern match 
        endDate = simpleDateFormat.parse("28-AUG-2019");// Ok 
    } catch (ParseException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

First, you can calculate the group means with aggregate:

means <- aggregate(weight ~  group, PlantGrowth, mean)

This dataset can be used with geom_text:

library(ggplot2)
ggplot(data=PlantGrowth, aes(x=group, y=weight, fill=group)) + geom_boxplot() +
  stat_summary(fun.y=mean, colour="darkred", geom="point", 
               shape=18, size=3,show_guide = FALSE) + 
  geom_text(data = means, aes(label = weight, y = weight + 0.08))

Here, + 0.08 is used to place the label above the point representing the mean.

An alternative version without ggplot2:

means <- aggregate(weight ~  group, PlantGrowth, mean)

boxplot(weight ~ group, PlantGrowth)
points(1:3, means$weight, col = "red")
text(1:3, means$weight + 0.08, labels = means$weight)

Sure. You can add a border to any layout you want. Basically, you need to create a custom drawable and add it as a background to your layout. example:

Create a file called customborder.xml in your drawable folder:

<?xml version="1.0" encoding="UTF-8"?>
 <shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
   <corners android:radius="20dp"/> 
   <padding android:left="10dp" android:right="10dp" android:top="10dp" android:bottom="10dp"/>
   <stroke android:width="1dp" android:color="#CCCCCC"/>
 </shape>

Now apply it as a background to your smaller layout:

<LinearLayout android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@drawable/customborder">

That should do the trick.

Also see:

This works for me:

protected boolean isTypeOf(String myClass, Class<?> superClass) {
    boolean isSubclassOf = false;
    try {
        Class<?> clazz = Class.forName(myClass);
        if (!clazz.equals(superClass)) {
            clazz = clazz.getSuperclass();
            isSubclassOf = isTypeOf(clazz.getName(), superClass);
        } else {
            isSubclassOf = true;
        }

    } catch(ClassNotFoundException e) {
        /* Ignore */
    }
    return isSubclassOf;
}

This is how I cleared my recyclerview and added new items to it with animation:

mList.clear();
mAdapter.notifyDataSetChanged();

mSwipeRefreshLayout.setRefreshing(false);

//reset adapter with empty array list (it did the trick animation)
mAdapter = new MyAdapter(context, mList);
recyclerView.setAdapter(mAdapter);

mList.addAll(newList);
mAdapter.notifyDataSetChanged();

For setting select value with triggering selected:

$('select.opts').val('SEL1').change();

For setting option from a scope:

$('.selDiv option[value="SEL1"]')
    .attr('selected', 'selected')
    .change();

This code use selector to find out the select object with condition, then change the selected attribute by attr().

Futher, I recommend to add change() event after setting attribute to selected, by doing this the code will close to changing select by user.

If you're using latest spring boot (with jdbc starter and Hikari) you'll run into: java.lang.IllegalArgumentException: jdbcUrl is required with driverClassName. To solve this:

1. In your application.properties:

datasource.oracle.url=youroracleurl

2. In your application define as bean (@Primary is mandatory!):

@Bean
@Primary
@ConfigurationProperties("datasource.oracle")
public DataSourceProperties getDatasourceProperties() {
    return new DataSourceProperties();
}

@Bean
@ConfigurationProperties("datasource.oracle")
public DataSource getDatasource() {
    return getDatasourceProperties().initializeDataSourceBuilder()
           .username("username")
           .password("password")
           .build();
}

As you can see, the import command did work but is showing errors because it tried to locate the resources in vendor.css and couldn't find them

You should also upload your project structure and ensure that there aren't any path issues. Also, you could include the css file in the index.html or the Component template and webpack loader would extract it when built

I'm not positive what you're asking, but if you're looking for an example of when one would want to use a null key, I use them often in maps to represent the default case (i.e. the value that should be used if a given key isn't present):

Map<A, B> foo;
A search;
B val = foo.containsKey(search) ? foo.get(search) : foo.get(null);

HashMap handles null keys specially (since it can't call .hashCode() on a null object), but null values aren't anything special, they're stored in the map like anything else

You can do it the same way you do it with Mockito on real instances. For example you can chain stubs, the following line will make the first call do nothing, then second and future call to getResources will throw the exception :

// the stub of the static method
doNothing().doThrow(Exception.class).when(StaticResource.class);
StaticResource.getResource("string");

// the use of the mocked static code
StaticResource.getResource("string"); // do nothing
StaticResource.getResource("string"); // throw Exception

Thanks to a remark of Matt Lachman, note that if the default answer is not changed at mock creation time, the mock will do nothing by default. Hence writing the following code is equivalent to not writing it.

doNothing().doThrow(Exception.class).when(StaticResource.class);
StaticResource.getResource("string");

Though that being said, it can be interesting for colleagues that will read the test that you expect nothing for this particular code. Of course this can be adapted depending on how is perceived understandability of the test.

By the way, in my humble opinion you should avoid mocking static code if your crafting new code. At Mockito we think it's usually a hint to bad design, it might lead to poorly maintainable code. Though existing legacy code is yet another story.

Generally speaking if you need to mock private or static method, then this method does too much and should be externalized in an object that will be injected in the tested object.

Hope that helps.

There are two ways to fix these issues,

• 1st is simple without code change that is
  run your script by Python3,
  if you still want to run on python2 then after running your python script, when you are entering the input keep in mind

  1. if you want to enter string then just start typing down with "input goes with double-quote" and it will work in python2.7 and
  2. if you want to enter character then use the input with a single quote like 'your input goes here'
  3. if you want to enter number not an issue you simply type the number

• 2nd way is with code changes
  use the below import and run with any version of python

  1. from six.moves import input
  2. Use raw_input() function instead of input() function in your code with any import
  3. sanitise your code with str() function like str(input()) and then assign to any variable

As error implies:
name 'dude' is not defined i.e. for python 'dude' become variable here and it's not having any value of python defined type assigned
so only its crying like baby so if we define a 'dude' variable and assign any value and pass to it, it will work but that's not what we want as we don't know what user will enter and moreover we want to capture the user input.

Fact about these method:
input() function: This function takes the value and type of the input you enter as it is without modifying it type.
raw_input() function: This function explicitly converts the input you give into type string,

Note:
The vulnerability in input() method lies in the fact that the variable accessing the value of input can be accessed by anyone just by using the name of variable or method.

I do the following all the time:

$ du -sh backup-lr-May-02-2017-1493723588.tar.gz

NB:

-s, --summarize
            display only a total for each argument
-h, --human-readable
            print sizes in human readable format (e.g., 1K 234M 2G)

From MSDN:

Use an instance of Lazy to defer the creation of a large or resource-intensive object or the execution of a resource-intensive task, particularly when such creation or execution might not occur during the lifetime of the program.

In addition to James Michael Hare's answer, Lazy provides thread-safe initialization of your value. Take a look at LazyThreadSafetyMode enumeration MSDN entry describing various types of thread safety modes for this class.

There is a blog post with brief source code sample about how misuse of IEnumerable<T> can dramatically impact LINQ query performance: Entity Framework: IQueryable vs. IEnumerable.

If we dig deeper and look into the sources, we can see that there are obviously different extension methods are perfomed for IEnumerable<T>:

// Type: System.Linq.Enumerable
// Assembly: System.Core, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089
// Assembly location: C:\Windows\Microsoft.NET\Framework\v4.0.30319\System.Core.dll
public static class Enumerable
{
    public static IEnumerable<TSource> Where<TSource>(
        this IEnumerable<TSource> source, 
        Func<TSource, bool> predicate)
    {
        return (IEnumerable<TSource>) 
            new Enumerable.WhereEnumerableIterator<TSource>(source, predicate);
    }
}

and IQueryable<T>:

// Type: System.Linq.Queryable
// Assembly: System.Core, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089
// Assembly location: C:\Windows\Microsoft.NET\Framework\v4.0.30319\System.Core.dll
public static class Queryable
{
    public static IQueryable<TSource> Where<TSource>(
        this IQueryable<TSource> source, 
        Expression<Func<TSource, bool>> predicate)
    {
        return source.Provider.CreateQuery<TSource>(
            Expression.Call(
                null, 
                ((MethodInfo) MethodBase.GetCurrentMethod()).MakeGenericMethod(
                    new Type[] { typeof(TSource) }), 
                    new Expression[] 
                        { source.Expression, Expression.Quote(predicate) }));
    }
}

The first one returns enumerable iterator, and the second one creates query through the query provider, specified in IQueryable source.

In the old days, "/opt" was used by UNIX vendors like AT&T, Sun, DEC and 3rd-party vendors to hold "Option" packages; i.e. packages that you might have paid extra money for. I don't recall seeing "/opt" on Berkeley BSD UNIX. They used "/usr/local" for stuff that you installed yourself.

But of course, the true "meaning" of the different directories has always been somewhat vague. That is arguably a good thing, because if these directories had precise (and rigidly enforced) meanings you'd end up with a proliferation of different directory names.

According to the Filesystem Hierarchy Standard, /opt is for "the installation of add-on application software packages". /usr/local is "for use by the system administrator when installing software locally".

Use script tag with the type specified, simply include it before the dot:

script(type="text/javascript").
  if (10 == 10) {
    alert("working");
  }

This will compile to:

<script type="text/javascript">
  if (10 == 10) {
    alert("working");
  }
</script>

    // Using Swift 4, the code below works.
    // The problem is that String.index is a struct. Use dot notation to grab the integer part of it that you want: ".encodedOffset"
    let strx = "0123456789ABCDEF"
    let si = strx.index(of: "A")
    let i = si?.encodedOffset       // i will be an Int. You need "?" because it might be nil, no such character found.

    if i != nil {                   // You MUST deal with the optional, unwrap it only if not nil.
        print("i = ",i)
        print("i = ",i!)            // "!" str1ps off "optional" specification (unwraps i).
            // or
        let ii = i!
        print("ii = ",ii)

    }
    // Good luck.

you can use this

List<Car> requiredCars = cars.stream()
    .filter (t->  t!= null && StringUtils.startsWith(t.getName(),"M"))
    .collect(Collectors.toList());

There are two ways to write case statements, you seem to be using a combination of the two

case a.updatedDate
    when 1760 then 'Entered on' + a.updatedDate
    when 1710 then 'Viewed on' + a.updatedDate
    else 'Last Updated on' + a.updateDate
end

or

case 
    when a.updatedDate = 1760 then 'Entered on' + a.updatedDate
    when a.updatedDate = 1710 then 'Viewed on' + a.updatedDate
    else 'Last Updated on' + a.updateDate
end

are equivalent. They may not work because you may need to convert date types to varchars to append them to other varchars.

I was having the same problem.Turns out my Node.js was outdated. After upgrading it's working.

pow(2.0,1.0)
pow(2.0,2.0)
pow(2.0,3.0)

Your original question title is misleading. To just square, use 2*2.

You can use the dplyr package to easily remove those particular rows.

library(dplyr)
df <- filter(df, C != "Foo")

$('.tabDisable').on('keydown', function(e)
{ 
  if (e.keyCode == 9)  
  {
    e.preventDefault();
  }
});

Put .tabDisable to all tab disable DIVs Like

<div class='tabDisable'>First Div</div> <!-- Tab Disable Div -->
<div >Second Div</div> <!-- No Tab Disable Div -->
<div class='tabDisable'>Third Div</div> <!-- Tab Disable Div -->

Open the sql file in your text editor;

1. Search: utf8mb4_unicode_ci Replace: utf8_general_ci (Replace All)

2. Search: utf8mb4_unicode_520_ci Replace: utf8_general_ci (Replace All)

3. Search: utf8mb4 Replace: utf8 (Replace All)

Save and upload!

I tried the above options but none of them is working for me. Here is the solution

if(window.event)
   {
        if(window.event.clientX < 40 && window.event.clientY < 0)
        {
            alert("Browser back button is clicked...");
        }
        else
        {
            alert("Browser refresh button is clicked...");
        }
    }

You are trying to do a logarithm of something that is not positive.

Logarithms figure out the base after being given a number and the power it was raised to. log(0) means that something raised to the power of 2 is 0. An exponent can never result in 0*, which means that log(0) has no answer, thus throwing the math domain error

*Note: 0^0 can result in 0, but can also result in 1 at the same time. This problem is heavily argued over.

For Developer certificate, you need to create a developer .mobileprovision profile and install add it to your XCode. In case you want to distribute the app using an adhoc distribution profile you will require AdHoc Distribution certificate and private key installed in your keychain.

If you have not created the cert, here are steps to create it. Incase it has already been created by someone in your team, ask him to share the cert and private key. If that someone is no longer in your team then you can revoke the cert from developer account and create new.

In my case (Windows 7 64-bit), I just did the following:

• Removed the reference to C:\ProgramData\Oracle\Java\javapath; from the Path environment variable
• Removed files java, javaw and javaws from the C:\Windows\System32 folder

Afterwards, I closed all open command line consoles, reopened them and ran java -version.

ListBox will try to expand in height that is available.. When you set the Height property of ListBox you get a scrollviewer that actually works...

If you wish your ListBox to accodate the height available, you might want to try to regulate the Height from your parent controls.. In a Grid for example, setting the Height to Auto in your RowDefinition might do the trick...

JButton b3 = new JButton("CLOSE");

b3.setBounds(50, 375, 250, 50);

b3.addActionListener(new ActionListener() {
    public void actionPerformed(ActionEvent e)
    {
        System.exit(0);
    }
});

I actually found a better way using the jQuery approach

var box = {

config:{
 color: 'red'
},

init:function(config){
 $.extend(this.config,config);
}

};

var myBox = box.init({
 color: blue
});

Please note that if you made changes to textarea, after it had rendered; You will get the updated value instead of the initialized value.

<!doctype html>
<html lang="en">
    <head>
        <script src="http://code.jquery.com/jquery-latest.min.js" type="text/javascript"></script>
        <script>
            $(function () {
                $('#btnShow').click(function () {
                    alert('text:' + $('#addressFieldName').text() + '\n value:' + $('#addressFieldName').val());
                });
            });
            function updateAddress() {
                $('#addressFieldName').val('District: Peshawar \n');
            }
        </script>
    </head>
    <body>
        <?php
        $address = "School: GCMHSS NO.1\nTehsil: ,\nDistrict: Haripur";
        ?>
        <textarea id="addressFieldName" rows="4" cols="40" tabindex="5" ><?php echo $address; ?></textarea>
        <?php echo '<script type="text/javascript">updateAddress();</script>'; ?>
        <input type="button" id="btnShow" value='show' />
    </body>
</html>

As you can see the value of textarea will be different than the text in between the opening and closing tag of concern textarea.

You can use an open source library and NuGet package called LikeType that I created that will give you the GenericClass<int> behavior that you're looking for.

The code would look like:

public class SomeInt : LikeType<int>
{
    public SomeInt(int value) : base(value) { }
}

[TestClass]
public class HashSetExample
{
    [TestMethod]
    public void Contains_WhenInstanceAdded_ReturnsTrueWhenTestedWithDifferentInstanceHavingSameValue()
    {
        var myInt = new SomeInt(42);
        var myIntCopy = new SomeInt(42);
        var otherInt = new SomeInt(4111);

        Assert.IsTrue(myInt == myIntCopy);
        Assert.IsFalse(myInt.Equals(otherInt));

        var mySet = new HashSet<SomeInt>();
        mySet.Add(myInt);

        Assert.IsTrue(mySet.Contains(myIntCopy));
    }
}

newTitle is a local variable where you create the fields. So when that functions ends, the variable newTitle, does not exist anymore. (The JTextField that was referenced by newTitle does still exist however.)

Thus, increase the scope of the variable, so that you can access it another method.

public SomeFrame extends JFrame {
   JTextField myTitle;//can be used anywhere in this class

   creationOfTheFields()
   {
   //other code
      myTitle = new JTextField("spam");  
      myTitle.setBounds(80, 40, 225, 20);
      options.add(myTitle);
   //blabla other code
   }

   private void New_Name()  
   {  
      this.setTitle(myTitle.getText());  
   } 
}

You go to your "device manager", find your "network adapters", then should find the virtual wifi adapter, then right click it and enable it. After that, you start your cmd with admin privileges, then try:

netsh wlan start hostednetwork

This happens when you do not include a message when you try to commit using:

git commit

It launches an editor environment. Quit it by typing :q! and hitting enter.

It's going to take you back to the terminal without committing, so make sure to try again, this time pass in a message:

git commit -m 'Initial commit'

string.Concat(los.ToArray());

If you just want to concatenate the strings then use string.Concat() instead of string.Join().

Have adapted julmot's answer in order to get a more complete result. This method will also return styles where the class is part for the selector.

//Get all styles where the provided class is involved
//Input parameters should be css selector such as .myClass or #m
//returned as an array of tuples {selectorText:"", styleDefinition:""}
function getStyleWithCSSSelector(cssSelector) {
    var styleSheets = window.document.styleSheets;
    var styleSheetsLength = styleSheets.length;
    var arStylesWithCSSSelector = [];

    //in order to not find class which has the current name as prefix
    var arValidCharsAfterCssSelector = [" ", ".", ",", "#",">","+",":","["];

    //loop through all the stylessheets in the bor
    for(var i = 0; i < styleSheetsLength; i++){
        var classes = styleSheets[i].rules || styleSheets[i].cssRules;
        var classesLength = classes.length;
        for (var x = 0; x < classesLength; x++) {
            //check for any reference to the class in the selector string
            if(typeof classes[x].selectorText != "undefined"){
                var matchClass = false;

                if(classes[x].selectorText === cssSelector){//exact match
                    matchClass=true;
                }else {//check for it as part of the selector string
                    //TODO: Optimize with regexp
                    for (var j=0;j<arValidCharsAfterCssSelector.length; j++){
                        var cssSelectorWithNextChar = cssSelector+ arValidCharsAfterCssSelector[j];

                        if(classes[x].selectorText.indexOf(cssSelectorWithNextChar)!=-1){
                            matchClass=true;
                            //break out of for-loop
                            break;
                        }
                    }
                }

                if(matchClass === true){
                    //console.log("Found "+ cssSelectorWithNextChar + " in css class definition " + classes[x].selectorText);
                    var styleDefinition;
                    if(classes[x].cssText){
                        styleDefinition = classes[x].cssText;
                    } else {
                        styleDefinition = classes[x].style.cssText;
                    }
                    if(styleDefinition.indexOf(classes[x].selectorText) == -1){
                        styleDefinition = classes[x].selectorText + "{" + styleDefinition + "}";
                    }
                    arStylesWithCSSSelector.push({"selectorText":classes[x].selectorText, "styleDefinition":styleDefinition});
                }
            }
        }
    }
    if(arStylesWithCSSSelector.length==0) {
        return null;
    }else {
        return arStylesWithCSSSelector;    
    }
}

In addition, I've made a function which collects the css style definitions to the sub-tree of a root node your provide (through a jquery selector).

function getAllCSSClassDefinitionsForSubtree(selectorOfRootElement){
    //stack in which elements are pushed and poped from
    var arStackElements = [];
    //dictionary for checking already added css class definitions
    var existingClassDefinitions = {}

    //use jquery for selecting root element
    var rootElement = $(selectorOfRootElement)[0];
    //string with the complete CSS output
    var cssString = "";

    console.log("Fetching all classes used in sub tree of " +selectorOfRootElement);
    arStackElements.push(rootElement);
    var currentElement;

    while(currentElement = arStackElements.pop()){
        currentElement = $(currentElement);
        console.log("Processing element " + currentElement.attr("id"));

        //Look at class attribute of element 
        var classesString = currentElement.attr("class");
        if(typeof classesString != 'undefined'){
            var arClasses = classesString.split(" ");

            //for each class in the current element
            for(var i=0; i< arClasses.length; i++){

                //fetch the CSS Styles for a single class. Need to append the . char to indicate its a class
                var arStylesWithCSSSelector = getStyleWithCSSSelector("."+arClasses[i]);
                console.log("Processing class "+ arClasses[i]);

                if(arStylesWithCSSSelector != null){
                    //console.log("Found "+ arStylesWithCSSSelector.length + " CSS style definitions for class " +arClasses[i]);
                    //append all found styles to the cssString
                    for(var j=0; j< arStylesWithCSSSelector.length; j++){
                        var tupleStyleWithCSSSelector = arStylesWithCSSSelector[j];

                        //check if it has already been added
                        if(typeof existingClassDefinitions[tupleStyleWithCSSSelector.selectorText] === "undefined"){
                            //console.log("Adding " + tupleStyleWithCSSSelector.styleDefinition);
                            cssString+= tupleStyleWithCSSSelector.styleDefinition;
                            existingClassDefinitions[tupleStyleWithCSSSelector.selectorText] = true;
                        }else {
                            //console.log("Already added " + tupleStyleWithCSSSelector.styleDefinition);
                        }
                    }
                }
            }
        }
        //push all child elments to stack
        if(currentElement.children().length>0){
            arStackElements= arStackElements.concat(currentElement.children().toArray());
        }
    }

    console.log("Found " + Object.keys(existingClassDefinitions).length + " CSS class definitions");
    return cssString;
}

Note that if a class is defined several times with the same selector, the above function will only pick up the first. Note that the example uses jQuery (but cab relatively easily be rewritten to not use it)

The __del__ method, it will be called when the object is garbage collected. Note that it isn't necessarily guaranteed to be called though. The following code by itself won't necessarily do it:

del obj

The reason being that del just decrements the reference count by one. If something else has a reference to the object, __del__ won't get called.

There are a few caveats to using __del__ though. Generally, they usually just aren't very useful. It sounds to me more like you want to use a close method or maybe a with statement.

See the python documentation on __del__ methods.

One other thing to note: __del__ methods can inhibit garbage collection if overused. In particular, a circular reference that has more than one object with a __del__ method won't get garbage collected. This is because the garbage collector doesn't know which one to call first. See the documentation on the gc module for more info.

fig, ax = plt.subplots(figsize=(10,4))
for key, grp in df.groupby(['ticker']):
    ax.plot(grp['Date'], grp['adj_close'], label=key)

ax.legend()
plt.show()

This solution might be more relevant if you want more control in matlab.

Solution inspired by: https://stackoverflow.com/a/52526454/10521959

Global variables are not extern nor static by default on C and C++. When you declare a variable as static, you are restricting it to the current source file. If you declare it as extern, you are saying that the variable exists, but are defined somewhere else, and if you don't have it defined elsewhere (without the extern keyword) you will get a link error (symbol not found).

Your code will break when you have more source files including that header, on link time you will have multiple references to varGlobal. If you declare it as static, then it will work with multiple sources (I mean, it will compile and link), but each source will have its own varGlobal.

What you can do in C++, that you can't in C, is to declare the variable as const on the header, like this:

const int varGlobal = 7;

And include in multiple sources, without breaking things at link time. The idea is to replace the old C style #define for constants.

If you need a global variable visible on multiple sources and not const, declare it as extern on the header, and then define it, this time without the extern keyword, on a source file:

Header included by multiple files:

extern int varGlobal;

In one of your source files:

int varGlobal = 7;

Try .replace(/ /g,"_");

Edit: or .split(' ').join('_') if you have an aversion to REs

Edit: John Resig said:

If you're searching and replacing through a string with a static search and a static replace it's faster to perform the action with .split("match").join("replace") - which seems counter-intuitive but it manages to work that way in most modern browsers. (There are changes going in place to grossly improve the performance of .replace(/match/g, "replace") in the next version of Firefox - so the previous statement won't be the case for long.)

Alternatively You can use the brew or curl command for installing things, wherever apt-get is mentioned with a URL...

For example,

curl -O http://www.magentocommerce.com/downloads/assets/1.8.1.0/magento-1.8.1.0.tar.gz

I'm not sure, but I would guess they tested some sample of prime numbers and found that 31 gave the best distribution over some sample of possible Strings.

Rename the closing function as 'hide', for example and it will work.

function hide() {
    if(document.getElementById('benefits').style.display=='block') {
      document.getElementById('benefits').style.display='none';
    }
} 

It's way late but you should look at this. Not CLI I know but still worth just knocking out a little shell script to do what you need:

https://pypi.org/project/aws-list-all/

It's a python library that in it's own words:

"Project description List all resources in an AWS account, all regions, all services(*). Writes JSON files for further processing.

(*) No guarantees for completeness. Use billing alerts if you are worried about costs."

If using g++, make sure that you are not running gcc instead

One more reason, maybe your url include some hiden characters, such as '\n'.

If you define your url like below, this exception will raise:

url = '''
http://google.com
'''

because there are '\n' hide in the string. The url in fact become:

\nhttp://google.com\n

This is a more general answer to the missing "Select cond1, stmt1, ... else stmtelse" connstruction in R. It's a bit gassy, but it works an resembles the switch statement present in C

while (TRUE) {
  if (is.na(val)) {
    val <- "NULL"
    break
  }
  if (inherits(val, "POSIXct") || inherits(val, "POSIXt")) {
    val <- paste0("#",  format(val, "%Y-%m-%d %H:%M:%S"), "#")
    break
  }
  if (inherits(val, "Date")) {
    val <- paste0("#",  format(val, "%Y-%m-%d"), "#")
    break
  }
  if (is.numeric(val)) break
  val <- paste0("'", gsub("'", "''", val), "'")
  break
}

To continue displaying data in the input after selecting, do so:

VB.NET
Private Sub ComboBox1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles ComboBox1.KeyPress
    e.Handled = True
End Sub



C#
Private void ComboBox1_KeyPress(object sender, KeyPressEventArgs e)
{
    e.Handled = true;
}

Have you tried:

SELECT Cast( 2.555 as decimal(53,8))

This would return 2.55500000. Is that what you want?

UPDATE:

Apparently you can also use SQL_VARIANT_PROPERTY to find the precision and scale of a value. Example:

SELECT SQL_VARIANT_PROPERTY(Cast( 2.555 as decimal(8,7)),'Precision'),
SQL_VARIANT_PROPERTY(Cast( 2.555 as decimal(8,7)),'Scale')

returns 8|7

You may be able to use this in your conversion process...

You should have READ_EXTERNAL_STORAGE permission for reading sdcard. Add permission in manifest.xml

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

From android 6.0 or higher, your app must ask user to grant the dangerous permissions at runtime. Please refer this link Permissions overview

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
    if (checkSelfPermission(Manifest.permission.READ_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {
        ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.READ_EXTERNAL_STORAGE}, 0);
    }
}

EXEC sys.sp_configure N'max server memory (MB)', N'2147483646'
GO
RECONFIGURE WITH OVERRIDE
GO

What value you specify for the server memory is not important, as long as it differs from the current one.

Btw, the thing that causes the speedup is not the query cache, but the data cache.

Use this XPath expression:

/*/*/X/node()

This selects any node (element, text node, comment or processing instruction) that is a child of any X element that is a grand-child of the top element of the XML document.

To verify what is selected, here is this XSLT transformation that outputs exactly the selected nodes:

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output omit-xml-declaration="yes"/>
 <xsl:template match="/">
  <xsl:copy-of select="/*/*/X/node()"/>
 </xsl:template>
</xsl:stylesheet>

and it produces exactly the wanted, correct result:

   First Text Node #1            
    <y> Y can Have Child Nodes #                
        <child> deep to it </child>
    </y>            Second Text Node #2 
    <z />

Explanation:

1. As defined in the W3 XPath 1.0 Spec, "child::node() selects all the children of the context node, whatever their node type." This means that any element, text-node, comment-node and processing-instruction node children are selected by this node-test.

2. node() is an abbreviation of child::node() (because child:: is the primary axis and is used when no axis is explicitly specified).

This may or may not help you address your problem, OP, but to get the timezone of the current server relative to UTC (UT1, technically), do:

SELECT EXTRACT(TIMEZONE FROM now())/3600.0;

The above works by extracting the UT1-relative offset in minutes, and then converting it to hours using the factor of 3600 secs/hour.

Example:

SET SESSION timezone TO 'Asia/Kabul';
SELECT EXTRACT(TIMEZONE FROM now())/3600.0;
-- output: 4.5 (as of the writing of this post)

(docs).

I'm assuming you are talking about the event bubbling aspect of it. It would be helpful to see your HTML for the said span elements as well. I can't see why you'd want to change the core behavior like this, I don't find it at all annoying. I suggest going with your second block of code:

$('span').click(function (){
  doStuff2();
  doStuff1();
});

Most importantly I think you'll find it more organized if you manage all the events for a given element in the same block like you've illustrated. Can you explain why you find this annoying?

BLOB is for binary data (videos, images, documents, other)

CLOB is for large text data (text)

Maximum size on MySQL 2GB

Maximum size on Oracle 128TB

For iOS 7.* and iOS 6.1

The easiest method is to set the tableFooterView property:

- (void)viewDidLoad 
{
    [super viewDidLoad];

    // This will remove extra separators from tableview
    self.tableView.tableFooterView = [[UIView alloc] initWithFrame:CGRectZero];
}

For previous versions

You could add this to your TableViewController (this will work for any number of sections):

- (CGFloat)tableView:(UITableView *)tableView heightForFooterInSection:(NSInteger)section {
     // This will create a "invisible" footer
     return 0.01f;
 }

and if it is not enough, add the following code too:

- (UIView *)tableView:(UITableView *)tableView viewForFooterInSection:(NSInteger)section
{        
    return [UIView new];

    // If you are not using ARC:
    // return [[UIView new] autorelease];
}

UPDATE

This was an old answer. Nowadays you should just use click. For more advanced event firing, use dispatchEvent.

const body = document.body;_x000D_
_x000D_
body.addEventListener('click', e => {_x000D_
  console.log('clicked body');_x000D_
});_x000D_
_x000D_
console.log('Using click()');_x000D_
body.click();_x000D_
_x000D_
console.log('Using dispatchEvent');_x000D_
body.dispatchEvent(new Event('click'));

Original Answer

Here is what I use: http://jsfiddle.net/mendesjuan/rHMCy/4/

Updated to work with IE9+

/**
 * Fire an event handler to the specified node. Event handlers can detect that the event was fired programatically
 * by testing for a 'synthetic=true' property on the event object
 * @param {HTMLNode} node The node to fire the event handler on.
 * @param {String} eventName The name of the event without the "on" (e.g., "focus")
 */
function fireEvent(node, eventName) {
    // Make sure we use the ownerDocument from the provided node to avoid cross-window problems
    var doc;
    if (node.ownerDocument) {
        doc = node.ownerDocument;
    } else if (node.nodeType == 9){
        // the node may be the document itself, nodeType 9 = DOCUMENT_NODE
        doc = node;
    } else {
        throw new Error("Invalid node passed to fireEvent: " + node.id);
    }

     if (node.dispatchEvent) {
        // Gecko-style approach (now the standard) takes more work
        var eventClass = "";

        // Different events have different event classes.
        // If this switch statement can't map an eventName to an eventClass,
        // the event firing is going to fail.
        switch (eventName) {
            case "click": // Dispatching of 'click' appears to not work correctly in Safari. Use 'mousedown' or 'mouseup' instead.
            case "mousedown":
            case "mouseup":
                eventClass = "MouseEvents";
                break;

            case "focus":
            case "change":
            case "blur":
            case "select":
                eventClass = "HTMLEvents";
                break;

            default:
                throw "fireEvent: Couldn't find an event class for event '" + eventName + "'.";
                break;
        }
        var event = doc.createEvent(eventClass);
        event.initEvent(eventName, true, true); // All events created as bubbling and cancelable.

        event.synthetic = true; // allow detection of synthetic events
        // The second parameter says go ahead with the default action
        node.dispatchEvent(event, true);
    } else  if (node.fireEvent) {
        // IE-old school style, you can drop this if you don't need to support IE8 and lower
        var event = doc.createEventObject();
        event.synthetic = true; // allow detection of synthetic events
        node.fireEvent("on" + eventName, event);
    }
};

Note that calling fireEvent(inputField, 'change'); does not mean it will actually change the input field. The typical use case for firing a change event is when you set a field programmatically and you want event handlers to be called since calling input.value="Something" won't trigger a change event.

For an example using both, authentication on application level and HTTP Basic Authentication see one of my previous posts.

Similar to @Rikki, I solved this problem by upgrading matplotlib with pip install matplotlib --upgrade. If you can't upgrade uninstalling and reinstalling may work.

pip uninstall matplotlib
pip install matplotlib

The other answers didn't work for me. I found the answer in their documentation:

http://api.highcharts.com/highcharts#Series

Using this method (see JSFiddle example):

var chart = new Highcharts.Chart({
    chart: {
        renderTo: 'container'
    },

    series: [{
        data: [29.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4]        
    }]
});

// the button action
$('#button').click(function() {
    chart.series[0].setData([129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4, 29.9, 71.5, 106.4] );
});

Make sure you declare the package at the top. In my groovy code this stops at breakpoints:

package Pkg1

import java.awt.event.ItemEvent;

isMule = false

class LineItem {
    // Structure defining individual DB rows
    public String ACCOUNT_CODE
    public String ACCOUNT_DESC
...

This does not stop at breakpoints:

import java.awt.event.ItemEvent;

isMule = false

class LineItem {
    // Structure defining individual DB rows
    public String ACCOUNT_CODE
    public String ACCOUNT_DESC
...

You can set the hours, minutes, seconds and microseconds to whatever you like

datetime.datetime.today().replace(hour=0, minute=0, second=0, microsecond=0)

but trutheality's answer is probably best when they are all to be zero and you can just compare the .date()s of the times

Maybe it is faster though if you have to compare hundreds of datetimes because you only need to do the replace() once vs hundreds of calls to date()

Mostly likely middle click your mouse.

Or try Shift + Insert.

It all depends on terminal used and X11-config for mouse.

I've just written a plugin which uses .firstElementChild if possible, and falls back to iterating over each individual node if necessary:

(function ($) {
    var useElementChild = ('firstElementChild' in document.createElement('div'));

    $.fn.firstChild = function () {
        return this.map(function() {
            if (useElementChild) {
                return this.firstElementChild;
            } else {
                var node = this.firstChild;
                while (node) {
                    if (node.type === 1) {
                        break;
                    }
                    node = node.nextSibling;
                }
                return node;
            }
        });
    };
})(jQuery);

It's not as fast as a pure DOM solution, but in jsperf tests under Chrome 24 it was a couple of orders of magnitude faster than any other jQuery selector-based method.

I found an easy way

Object.prototype.parseSqlResult = function () {
    return JSON.parse(JSON.stringify(this[0]))
}

At db layer do the parsing as

let users= await util.knex.raw('select * from user')
    return users.parseSqlResult()

This will return elements as normal JSON array.

strtok can be very dangerous. It is not thread safe. Its intended use is to be called over and over in a loop, passing in the output from the previous call. The strtok function has an internal variable that stores the state of the strtok call. This state is not unique to each thread - it is global. If any other code uses strtok in another thread, you get problems. Not the kind of problems you want to track down either!

I'd recommend looking for a regex implementation, or using sscanf to pull apart the string.

Try this:

char strprint[256];
char text[256];
strcpy(text, "My string to test");
while ( sscanf( text, "%s %s", strprint, text) > 0 ) {
   printf("token: %s\n", strprint);
}

Note: The 'text' string is destroyed as it's separated. This may not be the preferred behaviour =)

I had the similar issue. The problem was in the passwords: the Keystore and private key used different passwords. (KeyStore explorer was used)

After creating Keystore with the same password as private key had the issue was resolved.

You can use setInterval:

var timer = setInterval( myFunction, 1000);

Just declare your function as myFunction or some other name, and then don't bind it to $('.more')'s live event.

Try this to be able to catch the thrown exception:

$server_name = "your server name";
$database_name = "your database name";
try {
   $conn = new PDO("sqlsrv:Server=$server_name;Database=$database_name;ConnectionPooling=0", "user_name", "password");
   $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
} catch(PDOException $e) {
    $e->getMessage();
}

you write the command on terminal/cmd adb install FileName.apk.

You need to specify the path where your chromedriver is located.

1. Download chromedriver for your desired platform from here.

2. Place chromedriver on your system path, or where your code is.

3. If not using a system path, link your chromedriver.exe (For non-Windows users, it's just called chromedriver):

   browser = webdriver.Chrome(executable_path=r"C:\path\to\chromedriver.exe")
   

   (Set executable_path to the location where your chromedriver is located.)

   If you've placed chromedriver on your System Path, you can shortcut by just doing the following:

   browser = webdriver.Chrome()

4. If you're running on a Unix-based operating system, you may need to update the permissions of chromedriver after downloading it in order to make it executable:

   chmod +x chromedriver

5. That's all. If you're still experiencing issues, more info can be found on this other StackOverflow article: Can't use chrome driver for Selenium

PHP syntax is little different in case of concatenation from JavaScript. Instead of (+) plus a (.) period is used for string concatenation.

<?php

$selectBox = '<select name="number">';
for ($i=1;$i<=100;$i++)

    $selectBox += '<option value="' . $i . '">' . $i . '</option>'; // <-- (Wrong) Replace + with .
    $selectBox .= '<option value="' . $i . '">' . $i . '</option>'; // <-- (Correct) Here + is replaced .
}
$selectBox += '</select>'; // <-- (Wrong) Replace + with .
$selectBox .= '</select>'; // <-- (Correct) Here + is replaced .
echo $selectBox;

?>

A matrix is really just a vector with a dim attribute (for the dimensions). So you can add dimensions to vec using the dim() function and vec will then be a matrix:

vec <- 1:49
dim(vec) <- c(7, 7)  ## (rows, cols)
vec

> vec <- 1:49
> dim(vec) <- c(7, 7)  ## (rows, cols)
> vec
     [,1] [,2] [,3] [,4] [,5] [,6] [,7]
[1,]    1    8   15   22   29   36   43
[2,]    2    9   16   23   30   37   44
[3,]    3   10   17   24   31   38   45
[4,]    4   11   18   25   32   39   46
[5,]    5   12   19   26   33   40   47
[6,]    6   13   20   27   34   41   48
[7,]    7   14   21   28   35   42   49

The problem is your angular material version, I have the same, and I have resolved this when I have installed the good version of angular material in local.

Hope it solve yours too.

Had the same problem with different casing.

Did a checkout to development (or master) then changed the name (the wrong name) to something else like test.

• git checkout development
• git branch -m wrong-name test

then change the name back to the right name

• git branch -m test right-name

then checkout to the right-name branch

• git checkout right-name

then it worked to push to the remote branch

• git push origin right-name

SHA-1 produces a 160-bit message (20 bytes), too large to be stored in an int or long value. As Ralph suggests, you could use BigInteger.

To get a (less-secure) int hash, you could return the hash code of the returned byte array.

Alternatively, if you don't really need SHA at all, you could just use the UUID's String hash code.

# extract numbers from garbage string:
s = '12//n,_@#$%3.14kjlw0xdadfackvj1.6e-19&*ghn334'
newstr = ''.join((ch if ch in '0123456789.-e' else ' ') for ch in s)
listOfNumbers = [float(i) for i in newstr.split()]
print(listOfNumbers)
[12.0, 3.14, 0.0, 1.6e-19, 334.0]

Installing CuDNN just involves placing the files in the CUDA directory. If you have specified the routes and the CuDNN option correctly while installing caffe it will be compiled with CuDNN.

You can check that using cmake. Create a directory caffe/build and run cmake .. from there. If the configuration is correct you will see these lines:

-- Found cuDNN (include: /usr/local/cuda-7.0/include, library: /usr/local/cuda-7.0/lib64/libcudnn.so)

-- NVIDIA CUDA:
--   Target GPU(s)     :   Auto
--   GPU arch(s)       :   sm_30
--   cuDNN             :   Yes

If everything is correct just run the make orders to install caffe from there.

Plain Old Data

In short, it is all built-in data types (e.g. int, char, float, long, unsigned char, double, etc.) and all aggregation of POD data. Yes, it's a recursive definition. ;)

To be more clear, a POD is what we call "a struct": a unit or a group of units that just store data.

Iterate over the Array. First initialize the maximum value to the first element of the array and then for each element optimize it if the element under consideration is greater.

The goal is to make the <body> element take up the available height of the screen.

If you don't expect your content to take up more than the height of the screen, or you plan to make an inner scrollable element, set

body {
  height: 100vh;
}

otherwise, you want <body> to become scrollable when there is more content than the screen can hold, so set

body {
  min-height: 100vh;
}

this alone achieves the goal, albeit with a possible, and probably desirable, refinement.

Removing the margin of <body>.

body {
  margin: 0;
}

there are two main reasons for doing so.

1. <body> reaches the edge of the window.
   
2. <body> no longer has a scroll bar from the get-go.

P.S. if you want the background to be a radial gradient with its center in the center of the screen and not in the bottom right corner as with your example, consider using something like

body {
  min-height: 100vh;
  margin: 0;
  background: radial-gradient(circle, rgba(255,255,255,1) 0%, rgba(0,0,0,1) 100%);
}

Aside from @JsonIgnore, there are a couple of other possibilities:

• Use JSON Views to filter out fields conditionally (by default, not used for deserialization; in 2.0 will be available but you can use different view on serialization, deserialization)
• @JsonIgnoreProperties on class may be useful

Many embedded systems have a limited snprintf function that doesn't handle floats. I wrote this, and it does the trick fairly efficiently. I chose to use 64-bit unsigned integers to be able to handle large floats, so feel free to reduce them down to 16-bit or whatever needs you may have with limited resources.

#include <stdio.h>   // for uint64_t support.


int  snprintf_fp( char destination[], size_t available_chars, int decimal_digits,
                  char tail[], float source_number )
{
    int   chars_used  = 0;    // This will be returned.


    if ( available_chars > 0 )
    {
        // Handle a negative sign.
        if ( source_number < 0 )
        {
            // Make it positive
            source_number = 0 - source_number;
            destination[ 0 ] = '-';
            ++chars_used;
        }

        // Handle rounding
        uint64_t zeros = 1;
        for ( int i = decimal_digits; i > 0; --i )
            zeros *= 10;

        uint64_t source_num = (uint64_t)( ( source_number * (float)zeros ) + 0.5f );

        // Determine sliding divider max position.
        uint64_t  div_amount = zeros;       // Give it a head start
        while ( ( div_amount * 10 ) <= source_num )
            div_amount *= 10;

        // Process the digits
        while ( div_amount > 0 )

You can also use between:

df[df.some_date.between(start_date, end_date)]

if you want to select a single value then use $('#select').val(1).change()

if you want to select multiple values then set value in array so you can use this code $('#select').val([1,2,3]).change()

Yep, Use a better option source filter. If you're searching with JSON it'll look something like this:

{
    "_source": ["user", "message", ...],
    "query": ...,
    "size": ...
}

In ES 2.4 and earlier, you could also use the fields option to the search API:

{
    "fields": ["user", "message", ...],
    "query": ...,
    "size": ...
}

This is deprecated in ES 5+. And source filters are more powerful anyway!

I think I found the answer:

convert(nvarchar(50), RequestID)

Here's the link where I found this info:

<button disabled=true>text here</button>

You can still use an attribute. Just use the 'disabled' attribute instead of 'value'.

try boost::asio lib (http://www.boost.org/doc/libs/1_36_0/doc/html/boost_asio.html) it have lot examples.

If you are making a web application or a secured page you should always use (only when possible)

===

because it will will check if it is the same content and if it is the same type!

so when someone enters:

var check = 1;
if(check == '1') {
    //someone continued with a string instead of number, most of the time useless for your webapp, most of the time entered by a user who does not now what he is doing (this will sometimes let your app crash), or even worse it is a hacker searching for weaknesses in your webapp!
}

but with

var check = 1;
if(check === 1) {
    //some continued with a number (no string) for your script
} else {
    alert('please enter a real number');
}

a hacker will never get deeper in the system to find bugs and hack your app or your users

my point it is that the

===

will add more security to your scripts

of course you can also check if the entered number is valid, is a string, etc.. with other if statements inside the first example, but this is for at least me more easier to understand and use

The reason I posted this is that the word 'more secure' or 'security' has never been said in this conversation (if you look at iCloud.com it uses 2019 times === and 1308 times ==, this also means that you sometimes have the use == instead of === because it will otherwise block your function, but as said in the begin you should use === as much as possible)

In Rails 3.2.18, :decimal turns into :integer when using SQLServer, but it works fine in SQLite. Switching to :float solved this issue for us.

The lesson learned is "always use homogeneous development and deployment databases!"

Variable i is your looking key name.

You don't need to write a program to do this in Linux. Just pipe the serial port through netcat:

netcat www.example.com port </dev/ttyS0 >/dev/ttyS0

Just replace the address and port information. Also, you may be using a different serial port (i.e. change the /dev/ttyS0 part). You can use the stty or setserial commands to change the parameters of the serial port (baud rate, parity, stop bits, etc.).

What Arne said - you can't reliably style select boxes and have them look anything like consistent across browsers.

Uniform: https://github.com/pixelmatrix/uniform is a javascript solution which gives you good graphic control over your form elements - it's still Javascript, but it's about as nice as javascript gets for solving this problem.

These do the same thing:

window.location.assign(url);
window.location = url;
window.location.href = url;

They simply navigate to the new URL. The replace method on the other hand navigates to the URL without adding a new record to the history.

So, what you have read in those many forums is not correct. The assign method does add a new record to the history.

Reference: https://developer.mozilla.org/en-US/docs/Web/API/Window/location

The favicon is declared in the head tag with something like:

<link rel="shortcut icon" type="image/ico" href="favicon.ico">

You should be able to just pass the name of the icon you want along in the view data and throw it into the head tag.

There are many possible answers for this problem. The most common and most likely is that you're running another program which is blocking port 80 or 443. If you've installed Skype, then you've found your problem! Change apache's port settings to 81 and apache will work. There's a good tutorial on that To check this you can open up your command line by clicking the start menu, and typing 'cmd', and enter the command

    netstat -nab

this wil return a list of programs that will vaguely resemble this pattern

    [someprogram.exe]
    UDP     [fe80::numbers:numbers:numbers:numbers%numbers]:portnumber

You need to find a line (or lines) ending in :80 and terminate them in order to start apache. If there is no line ending in :80, there are more things you can do.

First, navigate to xampp's directory (default is c:\xampp) and double click apache_start.bat. This will open up a comand line and return more detailed errors about why apache can't run. Mostly, be looking for syntax errors that you could've created by editing your httpd.conf, or httpd-ssl.conf files. This is very easy to do if you've edited it and are a new user.

If still this fails, your last hope is to check the apache error log by clicking on the logs tab in apache's row in the xampp control panel and clicking error log.

If none of this works, don't give up! You got this!

Edit: If you change the port of apache, you will also have to go into httpd.conf (located in xampp/apache/conf) and near line 184, replace

ServerName localhost:80

with

ServerName localhost:81

It is also possible to specify port 81 in the url of your localhost, i.e.

localhost:81/my_project.php

This is what I am doing. It simply doesn't check the certificate anymore.

// always verify the host - dont check for certificate
final static HostnameVerifier DO_NOT_VERIFY = new HostnameVerifier() {
    public boolean verify(String hostname, SSLSession session) {
        return true;
    }
};

/**
 * Trust every server - dont check for any certificate
 */
private static void trustAllHosts() {
    // Create a trust manager that does not validate certificate chains
    TrustManager[] trustAllCerts = new TrustManager[] { new X509TrustManager() {
        public java.security.cert.X509Certificate[] getAcceptedIssuers() {
            return new java.security.cert.X509Certificate[] {};
        }

        public void checkClientTrusted(X509Certificate[] chain,
                String authType) throws CertificateException {
        }

        public void checkServerTrusted(X509Certificate[] chain,
                String authType) throws CertificateException {
        }
    } };

    // Install the all-trusting trust manager
    try {
        SSLContext sc = SSLContext.getInstance("TLS");
        sc.init(null, trustAllCerts, new java.security.SecureRandom());
        HttpsURLConnection
                .setDefaultSSLSocketFactory(sc.getSocketFactory());
    } catch (Exception e) {
        e.printStackTrace();
    }
}

and

    HttpURLConnection http = null;

    if (url.getProtocol().toLowerCase().equals("https")) {
        trustAllHosts();
        HttpsURLConnection https = (HttpsURLConnection) url.openConnection();
        https.setHostnameVerifier(DO_NOT_VERIFY);
        http = https;
    } else {
        http = (HttpURLConnection) url.openConnection();
    }

An answer has already been accepted, but in these situations, a more elegant solution in my opinion would be to use error handling.

    try {
        $user = User::where('mobile', Input::get('mobile'))->first();
    } catch (ErrorException $e) {
        // Do stuff here that you need to do if it doesn't exist.
        return View::make('some.view')->with('msg', $e->getMessage());
    }

User order by with that field, and then do distinct.

ProductOrder.objects.order_by('category').values_list('category', flat=True).distinct()

Here you've got a very detailed explanation of their differences

http://kyleschaeffer.com/development/css-font-size-em-vs-px-vs-pt-vs/

The jist of it (from source)

Pixels are fixed-size units that are used in screen media (i.e. to be read on the computer screen). Pixel stands for "picture element" and as you know, one pixel is one little "square" on your screen. Points are traditionally used in print media (anything that is to be printed on paper, etc.). One point is equal to 1/72 of an inch. Points are much like pixels, in that they are fixed-size units and cannot scale in size.

If you want it to be dynamic, so that the value of the variable at the time of the click is used, do the following:

<script language="javascript" type="text/javascript">
var scrt_var = 10; 
</script>
<a href="2.html" onclick="location.href=this.href+'?key='+scrt_var;return false;">Link</a>

Of course, that's the quick and dirty solution. You should really have a script that after DOM load adds an onclick handler to all relevant <a> elements.

Maybe in your data source add a column which does a sumif over all rows. Not sure what your data looks like but something like =(sumif([column holding pivot row heads),[current row head value in row], probability column)>.2). This will give you a True when the pivot table will show >20%.
Then add a filter on your pivot table on this column for TRUE values

Here is a real life sample. Note that String also implements Comparable.

class Author implements Comparable<Author>{
    String firstName;
    String lastName;

    @Override
    public int compareTo(Author other){
        // compareTo should return < 0 if this is supposed to be
        // less than other, > 0 if this is supposed to be greater than 
        // other and 0 if they are supposed to be equal
        int last = this.lastName.compareTo(other.lastName);
        return last == 0 ? this.firstName.compareTo(other.firstName) : last;
    }
}

later..

/**
 * List the authors. Sort them by name so it will look good.
 */
public List<Author> listAuthors(){
    List<Author> authors = readAuthorsFromFileOrSomething();
    Collections.sort(authors);
    return authors;
}

/**
 * List unique authors. Sort them by name so it will look good.
 */
public SortedSet<Author> listUniqueAuthors(){
    List<Author> authors = readAuthorsFromFileOrSomething();
    return new TreeSet<Author>(authors);
}

The best working Solution of adding Custom header view in UITableView for section in swift 4 is --

1 first Use method ViewForHeaderInSection as below -

func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
        let headerView = UIView.init(frame: CGRect.init(x: 0, y: 0, width: tableView.frame.width, height: 50))

        let label = UILabel()
        label.frame = CGRect.init(x: 5, y: 5, width: headerView.frame.width-10, height: headerView.frame.height-10)
        label.text = "Notification Times"
        label.font = UIFont().futuraPTMediumFont(16) // my custom font
        label.textColor = UIColor.charcolBlackColour() // my custom colour

        headerView.addSubview(label)

        return headerView
    }

2 Also Don't forget to set Height of the header using heightForHeaderInSection UITableView method -

func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
        return 50
    }

and you're all set

It is indeed possible.

Here is an example calling the Weather SOAP Service using plain requests lib:

import requests
url="http://wsf.cdyne.com/WeatherWS/Weather.asmx?WSDL"
#headers = {'content-type': 'application/soap+xml'}
headers = {'content-type': 'text/xml'}
body = """<?xml version="1.0" encoding="UTF-8"?>
         <SOAP-ENV:Envelope xmlns:ns0="http://ws.cdyne.com/WeatherWS/" xmlns:ns1="http://schemas.xmlsoap.org/soap/envelope/" 
            xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
            <SOAP-ENV:Header/>
              <ns1:Body><ns0:GetWeatherInformation/></ns1:Body>
         </SOAP-ENV:Envelope>"""

response = requests.post(url,data=body,headers=headers)
print response.content

Some notes:

• The headers are important. Most SOAP requests will not work without the correct headers. application/soap+xml is probably the more correct header to use (but the weatherservice prefers text/xml
• This will return the response as a string of xml - you would then need to parse that xml.
• For simplicity I have included the request as plain text. But best practise would be to store this as a template, then you can load it using jinja2 (for example) - and also pass in variables.

For example:

from jinja2 import Environment, PackageLoader
env = Environment(loader=PackageLoader('myapp', 'templates'))
template = env.get_template('soaprequests/WeatherSericeRequest.xml')
body = template.render()

Some people have mentioned the suds library. Suds is probably the more correct way to be interacting with SOAP, but I often find that it panics a little when you have WDSLs that are badly formed (which, TBH, is more likely than not when you're dealing with an institution that still uses SOAP ;) ).

You can do the above with suds like so:

from suds.client import Client
url="http://wsf.cdyne.com/WeatherWS/Weather.asmx?WSDL"
client = Client(url)
print client ## shows the details of this service

result = client.service.GetWeatherInformation() 
print result 

Note: when using suds, you will almost always end up needing to use the doctor!

Finally, a little bonus for debugging SOAP; TCPdump is your friend. On Mac, you can run TCPdump like so:

sudo tcpdump -As 0 

This can be helpful for inspecting the requests that actually go over the wire.

The above two code snippets are also available as gists:

• SOAP Request with requests
• SOAP Request with suds

You can use the following attributes for webkit, which reach into the shadow DOM:

::-webkit-scrollbar              { /* 1 */ }
::-webkit-scrollbar-button       { /* 2 */ }
::-webkit-scrollbar-track        { /* 3 */ }
::-webkit-scrollbar-track-piece  { /* 4 */ }
::-webkit-scrollbar-thumb        { /* 5 */ }
::-webkit-scrollbar-corner       { /* 6 */ }
::-webkit-resizer                { /* 7 */ }

Here's a working fiddle with a red scrollbar, based on code from this page explaining the issues.

http://jsfiddle.net/hmartiro/Xck2A/1/

Using this and your solution, you can handle all browsers except Firefox, which at this point I think still requires a javascript solution.

Combining the input from everyone else (use not, no parens, use os.mkdir) you'd get...

special_path_for_john = "/usr/share/sounds/blues"
if not os.path.exists(special_path_for_john):
    os.mkdir(special_path_for_john)

Use font property of UILabel:

label.font = UIFont(name:"HelveticaNeue-Bold", size: 16.0)

or use default system font to bold text:

label.font = UIFont.boldSystemFont(ofSize: 16.0)

On the same theme as other answers, keeping it simple

Sub PrintArray(Data As Variant, Cl As Range)
    Cl.Resize(UBound(Data, 1), UBound(Data, 2)) = Data
End Sub


Sub Test()
    Dim MyArray() As Variant

    ReDim MyArray(1 To 3, 1 To 3) ' make it flexible

    ' Fill array
    '  ...

    PrintArray MyArray, ActiveWorkbook.Worksheets("Sheet1").[A1]
End Sub

Use the Database menu and "Set Datasource Location" menu option to change the name or location of each table in a report.

This works for changing the location of a database, changing to a new database, and changing the location or name of an individual table being used in your report.

To change the datasource connection, go the Database menu and click Set Datasource Location.

1. Change the Datasource Connection:
   1. From the Current Data Source list (the top box), click once on the datasource connection that you want to change.
   2. In the Replace with list (the bottom box), click once on the new datasource connection.
   3. Click Update.
2. Change Individual Tables:
   4. From the Current Data Source list (the top box), expand the datasource connection that you want to change.
   5. Find the table for which you want to update the location or name.
   6. In the Replace with list (the bottom box), expand the new datasource connection.
   7. Find the new table you want to update to point to.
   8. Click Update.
   9. Note that if the table name has changed, the old table name will still appear in the Field Explorer even though it is now using the new table. (You can confirm this be looking at the Table Name of the table's properties in Current Data Source in Set Datasource Location. Screenshot http://i.imgur.com/gzGYVTZ.png) It's possible to rename the old table name to the new name from the context menu in Database Expert -> Selected Tables.
3. Change Subreports:
   9. Repeat each of the above steps for any subreports you might have embedded in your report.
   10. Close the Set Datasource Location window.
4. Any Commands or SQL Expressions:
   11. Go to the Database menu and click Database Expert.
   12. If the report designer used "Add Command" to write custom SQL it will be shown in the Selected Tables box on the right.
   13. Right click that command and choose "Edit Command".
   14. Check if that SQL is specifying a specific database. If so you might need to change it.
   15. Close the Database Expert window.
   16. In the Field Explorer pane on the right, right click any SQL Expressions.
   17. Check if the SQL Expressions are specifying a specific database. If so you might need to change it also.
   18. Save and close your Formula Editor window when you're done editing.

And try running the report again.

The key is to change the datasource connection first, then any tables you need to update, then the other stuff. The connection won't automatically change the tables underneath. Those tables are like goslings that've imprinted on the first large goose-like animal they see. They'll continue to bypass all reason and logic and go to where they've always gone unless you specifically manually change them.

To make it more convenient, here's a tip: You can "Show SQL Query" in the Database menu, and you'll see table names qualified with the database (like "Sales"."dbo"."Customers") for any tables that go straight to a specific database. That might make the hunting easier if you have a lot of stuff going on. When I tackled this problem I had to change each and every table to point to the new table in the new database.

Edited:

To give margin to any control you could wrap the control with border like this

<!--...-->
    <Border Padding="10">
            <AnyControl>
<!--...-->

Both are similar in functionality because they both return type information, however I personally prefer instanceof because it's comparing actual types rather than strings. Type comparison is less prone to human error, and it's technically faster since it's comparing pointers in memory rather than doing whole string comparisons.

If you facing grant permission access denied problem, you can try mysql to fix the problem:

grant all privileges on . to root@'localhost' identified by 'Your password';

grant all privileges on . to root@'IP ADDRESS' identified by 'Your password?';

your can try this on any mysql user, its working.

Use below command to login mysql with iP address.

mysql -h 10.0.0.23 -u root -p

I had the same problem. Just after enabling Internet Virtualization from BIOS. After that let the system boot and install HAXM once again. Now emulator will run faster than before and HAXM will work. Enjoy!!

Or, alternatively, you can take a list comprehension approach:

>>> mylis = ['this is test', 'another test']
>>> [item.upper() for item in mylis]
['THIS IS TEST', 'ANOTHER TEST']

SELECT
[DATABASE] = DB_NAME(DBID), 
OPNEDCONNECTIONS =COUNT(DBID),
[USER] =LOGINAME
FROM SYS.SYSPROCESSES
GROUP BY DBID, LOGINAME
ORDER BY DB_NAME(DBID), LOGINAME

Get Schema Name and Table Name from a database.

        public IList<Tuple<string, string>> ListTables()
        {

            DataTable dt = con.GetSchema("Tables");

            var tables = new List<Tuple<string, string>>();

            foreach (DataRow row in dt.Rows)
            {
            string schemaName = (string)row[1];
            string tableName = (string)row[2];
            //AddToList();
            tables.Add(Tuple.Create(schemaName, tableName));
            Console.WriteLine(schemaName +" " + tableName) ;
            }
            return tables;
        }

Well this error is actually rather straight forward.  it simply means that your file does not exist up within the S3 bucket.  Several things could be wrong:

1. You could be trying to reference the wrong file.  Double check the path that you tried to retrieve.

2. Whenever the file was uploaded it must have failed.  Check the logs for your S3Sync process to see if you can find any relevant output
