Make this entry in dimens

<!--Floating action button-->
<dimen name="design_fab_image_size" tools:override="true">36dp</dimen>

Here 36dp is icon size on floating point button. This will set 36dp size for all icons for floating action button.

Updates As Per Comments

If you want to set icon size to particular Floating Action Button just go with Floating action button attributes like app:fabSize="normal" and android:scaleType="center".

  <!--app:fabSize decides size of floating action button You can use normal, auto or mini as per need-->
  app:fabSize="normal" 

  <!--android:scaleType decides how the icon drawable will be scaled on Floating action button. You can use center(to show scr image as original), fitXY, centerCrop, fitCenter, fitEnd, fitStart, centerInside.-->
  android:scaleType="center"

you should try this

g++-4.4 -std=c++0x or g++-4.7 -std=c++0x

[^a-zA-Z0-9] is a character class matches any non-alphanumeric characters.

Alternatively, [^\w\d] does the same thing.

Usage:

string regExp = "[^\w\d]";
string tmp = Regex.Replace(n, regExp, "");

Instead of ISNULL(), use NVL().

T-SQL:

SELECT ISNULL(SomeNullableField, 'If null, this value') FROM SomeTable

PL/SQL:

SELECT NVL(SomeNullableField, 'If null, this value') FROM SomeTable

1.find table "dbo._EFMigrationsHistory", then delete the migration record that you want to remove. 2. run "remove-migration" in PM(Package Manager Console). Works for me.

var val = $("#checkboxId").is(":checked");

In most cases getting rid of infinite and null values solve this problem.

get rid of infinite values.

df.replace([np.inf, -np.inf], np.nan, inplace=True)

get rid of null values the way you like, specific value such as 999, mean, or create your own function to impute missing values

df.fillna(999, inplace=True)

The documentation says (also here):

If npm was invoked with root privileges, then it will change the uid to the user account or uid specified by the user config, which defaults to nobody. Set the unsafe-perm flag to run scripts with root privileges.

Your options are:

1. Run npm install with the --unsafe-perm flag:

   [sudo] npm install --unsafe-perm
   

2. Add the unsafe-perm flag to your package.json:

   "config": {
       "unsafe-perm":true
   }
   

3. Don't use the preinstall script to install global modules, install them separately and then run the regular npm install without root privileges:

   sudo npm install -g coffee-script node-gyp
   npm install

This works from Java 5 to 7:

public int getTheNumber(Integer... factors) {
    ArrayList<Integer> f = new ArrayList<Integer>(Arrays.asList(factors));
    Collections.sort(f);
    return f.get(0)*f.get(f.size()-1);
}

In Java 4 there is no vararg... :-)

Already coded in my library so here it is:

var vScrollWidth = window.screen.width - window.document.documentElement.clientWidth;

I should mention that jQuery $(window).width() can also be used instead of window.document.documentElement.clientWidth.

It doesn't work if you open developer tools in firefox on the right but it overcomes it if the devs window is opened at bottom!

window.screen is supported quirksmode.org!

Have fun!

Using the isDebugEnabled() is reserved for when you're building up log messages by concatenating Strings:

Var myVar = new MyVar();
log.debug("My var is " + myVar + ", value:" + myVar.someCall());

However, in your example there is no speed gain as you're just logging a String and not performing operations such as concatenation. Therefore you're just adding bloat to your code and making it harder to read.

I personally use the Java 1.5 format calls in the String class like this:

Var myVar = new MyVar();
log.debug(String.format("My var is '%s', value: '%s'", myVar, myVar.someCall()));

I doubt there's much optimisation but it's easier to read.

Do note though that most logging APIs offer formatting like this out of the box: slf4j for example provides the following:

logger.debug("My var is {}", myVar);

which is even easier to read.

I'm not sure how necessary this is, and it adds a call to getElementById, but if you're really keen on getting inline JavaScript out of your code, you can pass it as an HTML attribute, namely:

<span class="metadata" id="metadata-size-of-widget" title="<?php echo json_encode($size_of_widget) ?>"></span>

And then in your JavaScript:

var size_of_widget = document.getElementById("metadata-size-of-widget").title;

That's my solution

<div class="main" style="width: 100%;">
    <div class="container">
        <div class="sizing"></div>
        <div class="content"></div>
    </div>
</div>

.main {
    width: 100%;
}
.container {
    width: 30%;
    float: right;
    position: relative;
}
.sizing {
    width: 100%;
    padding-bottom: 50%;
    visibility: hidden;
}
.content {
    width: 100%;
    height: 100%;
    background-color: red;
    position: absolute;
    margin-top: -50%;
}

All the model fields which have definite types, those should be validated when returned to Controller. If any of the model fields are not matching with their defined type, then ModelState.IsValid will return false. Because, These errors will be added in ModelState.

To do it in place, you can use the RemoveAll method of the "List<>" class along with a custom "Predicate" class...but all that does is clean up the code... under the hood it's doing the same thing you are...but yes, it does it in place, so you do same the temp list.

You can also do it without the [xml] cast. (Although xpath is a world unto itself. https://www.w3schools.com/xml/xml_xpath.asp)

$xml = (select-xml -xpath / -path stack.xml).node
$xml.objects.object.property

Or just this, xpath is case sensitive. Both have the same output:

$xml = (select-xml -xpath /Objects/Object/Property -path stack.xml).node
$xml

It's not in standard C, so the behavior is undefined.

Some implementation uses it to clear stdin buffer.

From C11 7.21.5.2 The fflush function, fflush works only with output/update stream, not input stream.

If stream points to an output stream or an update stream in which the most recent operation was not input, the fflush function causes any unwritten data for that stream to be delivered to the host environment to be written to the file; otherwise, the behavior is undefined.

NOTE: This is an incorrect solution as @benlemasurier proved

Here is a way to copy a slice. I'm a bit late, but there is a simpler, and faster answer than @Dave's. This are the instructions generated from a code like @Dave's. These is the instructions generated by mine. As you can see there are far fewer instructions. What is does is it just does append(slice), which copies the slice. This code:

package main

import "fmt"

func main() {
    var foo = []int{1, 2, 3, 4, 5}
    fmt.Println("foo:", foo)
    var bar = append(foo)
    fmt.Println("bar:", bar)
    bar = append(bar, 6)
    fmt.Println("foo after:", foo)
    fmt.Println("bar after:", bar)
}

Outputs this:

foo: [1 2 3 4 5]
bar: [1 2 3 4 5]
foo after: [1 2 3 4 5]
bar after: [1 2 3 4 5 6]

Solution for Netbeans 8.02 and 8.1 IDE and JBOSS EAP 6.4:

1. From the services tab of Netbeans, add JBOSS server to your "servers" node.

2. If you are using MAVEN, netbeans compiles files and maven copies files to ./target directory. You need to create a symbolic link from .\target to JBOSS_HOME\standalone\deployments. Under windows, an example command would be

   cd %JBOSS_HOME%\standalone\deployments mklink /d MyWebApplication.war %PROJECTS_HOME%\MyWebApplication\target\MyWebApplication-1.0.0

   The above creates a symbolic link from %JBOSS_HOME%\standalone\deployments\MyWebApplication.war to \target\MyWebApplication-1.0.0 which is where maven transfers all files after compilation, or after a jsp, html or any other file changes.

3. Last think to do is to create a CentralManagement.war.dodeploy file in %JBOSS_HOME%\standalone\deployments. This file will tell JBOSS to deploy the war "file" as a web application

This works like champ on mac os or windows.

Port 465: IANA has reassigned a new service to this port, and it should no longer be used for SMTP communications.

However, because it was once recognized by IANA as valid, there may be legacy systems that are only capable of using this connection method. Typically, you will use this port only if your application demands it. A quick Google search, and you'll find many consumer ISP articles that suggest port 465 as the recommended setup. Hopefully this ends soon! It is not RFC compliant.

Port 587: This is the default mail submission port. When a mail client or server is submitting an email to be routed by a proper mail server, it should always use this port.

Everyone should consider using this port as default, unless you're explicitly blocked by your upstream network or hosting provider. This port, coupled with TLS encryption, will ensure that email is submitted securely and following the guidelines set out by the IETF.

Port 25: This port continues to be used primarily for SMTP relaying. SMTP relaying is the transmittal of email from email server to email server.

In most cases, modern SMTP clients (Outlook, Mail, Thunderbird, etc) shouldn't use this port. It is traditionally blocked, by residential ISPs and Cloud Hosting Providers, to curb the amount of spam that is relayed from compromised computers or servers. Unless you're specifically managing a mail server, you should have no traffic traversing this port on your computer or server.

For the benefit of anyone who might believe e.g. that doing aset.add() in a loop would have performance competitive with doing aset.update(), here's an example of how you can test your beliefs quickly before going public:

>\python27\python -mtimeit -s"it=xrange(10000);a=set(xrange(100))" "a.update(it)"
1000 loops, best of 3: 294 usec per loop

>\python27\python -mtimeit -s"it=xrange(10000);a=set(xrange(100))" "for i in it:a.add(i)"
1000 loops, best of 3: 950 usec per loop

>\python27\python -mtimeit -s"it=xrange(10000);a=set(xrange(100))" "a |= set(it)"
1000 loops, best of 3: 458 usec per loop

>\python27\python -mtimeit -s"it=xrange(20000);a=set(xrange(100))" "a.update(it)"
1000 loops, best of 3: 598 usec per loop

>\python27\python -mtimeit -s"it=xrange(20000);a=set(xrange(100))" "for i in it:a.add(i)"
1000 loops, best of 3: 1.89 msec per loop

>\python27\python -mtimeit -s"it=xrange(20000);a=set(xrange(100))" "a |= set(it)"
1000 loops, best of 3: 891 usec per loop

Looks like the cost per item of the loop approach is over THREE times that of the update approach.

Using |= set() costs about 1.5x what update does but half of what adding each individual item in a loop does.

"C:\Program Files\PuTTY\pscp.exe" -scp file.py server.com:

or when the remote server has a different user, use "C:\Program Files\PuTTY\pscp.exe" -l username -scp file.py server.com:

After connecting to the server pscp will ask for a password.

I am not a fan of bumping old articles but because this was one of the first responses for this particular issue I felt a need to clarify something.

As @Bhavin Shah answer states the domain part of the url is case insensitive, so

http://google.com 

and

http://GOOGLE.COM 

and

http://GoOgLe.CoM 

are all the same but everything after the domain name part is considered case sensitive.

so...

http://GOOGLE.COM/ABOUT

and

http://GOOGLE.COM/about

are different.

Note: I am talking "technically" and not "literally" in a lot of cases, most actually, servers are setup to handle these items the same, but it is possible to set them up so they are NOT handled the same.

Different servers handle this differently and in some cases they Have to be case sensitive. In many cases query string values are encoded (such as Session Ids or Base64 encoded data thats passed as a query string value) These items are case sensitive by their nature so the server has to be case sensitive in handling them.

So to answer the question, "should" servers be case sensitive in grabbing this data, the answer is "yes, most definitely."

Of course not everything needs to be case sensitive but the server should be aware of what that is and how to handle those cases.

@Hart Simha's comment basically says the same thing. I missed it before I posted so I want to give credit where credit is due.

The tabularx package gives you

1. the total width as a first parameter, and
2. a new column type X, all X columns will grow to fill up the total width.

For your example:

\usepackage{tabularx}

\begin{document}
% ...

\begin{tabularx}{\textwidth}{|X|X|X|}
\hline
Input & Output& Action return \\
\hline
\hline
DNF &  simulation & jsp\\
\hline
\end{tabularx}

Same problem, but just re-installing SQL Management Studio 2008 R2 Service Pack 1 worked for me. I left my DB engine alone. The DB engine is not the problem, just SQL Management Studio getting hosed by Visual Studio SP1.

Are you setting up a local 'm4' directory? e.g.,

> aclocal -I m4 --install

Some packages come with an autogen.sh or initgen.sh shell script to run glibtoolize, autoheader, autoconf, automake. Here's an autogen.sh script I use:

#! /bin/sh

case `uname` in Darwin*) glibtoolize --copy ;;
  *) libtoolize --copy ;; esac

autoheader
aclocal -I m4 --install
autoconf

automake --foreign --add-missing --force-missing --copy

EDIT

You may need to add ACLOCAL_AMFLAGS = -I m4 to the top-level Makefile.am.

To get the all selected Items in a CheckedListBox try this:

In this case ths value is a String but it's run with other type of Object:

for (int i = 0; i < myCheckedListBox.Items.Count; i++)
{
    if (myCheckedListBox.GetItemChecked(i) == true)
    {

        MessageBox.Show("This is the value of ceckhed Item " + myCheckedListBox.Items[i].ToString());

    }

}

I suggest you step through the code in your debugger as debugging programs is what it is for.

What I would expect you would see is that every time the code loops int x = 0; is set.

It would be awesome if someone also knows the steps for setting this up in Eclipse (I assume it's as simple as setting up an annotation processor, but you never know)

One more related question, since it took me forever to find the answer:

How to make the legend background blank (i.e. transparent, not white):

legend = plt.legend()
legend.get_frame().set_facecolor('none')

Warning, you want 'none' (the string). None means the default color instead.

<script src="myjs.js"></script>
</body>

script tag should be use always before body close or Bottom in HTML file.

Page will load with html and css and later js will load.

check this if require : http://stevesouders.com/hpws/rule-js-bottom.php

I also had entries in:

/Library/Receipts/InstallHistory.plist

that i had to delete.

The best way to protect your input it's use htmlentities function. Example:

htmlentities($target, ENT_QUOTES, 'UTF-8');

You can get more information here.

Here is another reason why errors might not be visible:

I had the same issue. In my case, I had copied the source from a production environment. Hence the ENVIRONMENT variable defined in index.php was set to 'production'. This caused error_reporting to be set to 0 (no logging). Just set it to 'development' and you should start seeing error messages in apache log.

Turned out the 500 was due to a semi colon missing in database config :-)

WARNING! I have a very strong view on this subject.

.NET’s existing web clients are not developer friendly! WebRequest & WebClient are prime examples of "how to frustrate a developer". They are verbose & complicated to work with; when all you want to do is a simple Post request in C#. HttpClient goes some way in addressing these issues, but it still falls short. On top of that Microsoft’s documentation is bad … really bad; unless you want to sift through pages and pages of technical blurb.

Open-source to the rescue. There are three excellent open-source, free NuGet libraries as alternatives. Thank goodness! These are all well supported, documented and yes, easy - correction…super easy - to work with.

• ServiceStack.Text - fast, light and resilient.
• RestSharp - simple REST and HTTP API Client
• Flurl- a fluent, portable, testable HTTP client library

There is not much between them, but I would give ServiceStack.Text the slight edge …

• Github stars are roughly the same.
• Open Issues & importantly how quickly any issues closed down? ServiceStack takes the award here for the fastest issue resolution & no open issues.
• Documentation? All have great documentation; however, ServiceStack takes it to the next level & is known for its ‘Golden standard’ for documentation.

Ok - so what does a Post Request in JSON look like within ServiceStack.Text?

var response = "http://example.org/login"
    .PostJsonToUrl(new Login { Username="admin", Password="mypassword" });

That is one line of code. Concise & easy! Compare the above to .NET’s Http libraries.

You may use Upsert with $setOnInsert operator.

db.Table.update({noExist: true}, {"$setOnInsert": {xxxYourDocumentxxx}}, {upsert: true})

You can't use an aggregate directly in a WHERE clause; that's what HAVING clauses are for.

You can use a sub-query which contains an aggregate in the WHERE clause.

for /f "tokens=* delims= " %%f in (myfile) do

This reads a file line-by-line, removing leading spaces (thanks, jeb).

set line=%%f

sets then the line variable to the line just read and

call :procesToken

calls a subroutine that does something with the line

:processToken

is the start of the subroutine mentioned above.

for /f "tokens=1* delims=/" %%a in ("%line%") do

will then split the line at /, but stopping tokenization after the first token.

echo Got one token: %%a

will output that first token and

set line=%%b

will set the line variable to the rest of the line.

if not "%line%" == "" goto :processToken

And if line isn't yet empty (i.e. all tokens processed), it returns to the start, continuing with the rest of the line.

If we consider the below example for converting the json format file to csv formatted file.

{
 "item_data" : [
      {
        "item": "10023456",
        "class": "100",
        "subclass": "123"
      }
      ]
}

The below code will convert the json file ( data3.json ) to csv file ( data3.csv ).

import json
import csv
with open("/Users/Desktop/json/data3.json") as file:
    data = json.load(file)
    file.close()
    print(data)

fname = "/Users/Desktop/json/data3.csv"

with open(fname, "w", newline='') as file:
    csv_file = csv.writer(file)
    csv_file.writerow(['dept',
                       'class',
                       'subclass'])
    for item in data["item_data"]:
         csv_file.writerow([item.get('item_data').get('dept'),
                            item.get('item_data').get('class'),
                            item.get('item_data').get('subclass')])

The above mentioned code has been executed in the locally installed pycharm and it has successfully converted the json file to the csv file. Hope this help to convert the files.

master = Tk()
entryb1 = StringVar

Label(master, text="Input: ").grid(row=0, sticky=W)

Entry(master, textvariable=entryb1).grid(row=1, column=1)

b1 = Button(master, text="continue", command=print_content)
b1.grid(row=2, column=1)

def print_content():
    global entryb1
    content = entryb1.get()
    print(content)

master.mainloop()

What you did wrong was not put it inside a Define function then you hadn't used the .get function with the textvariable you had set.

More explicitly:

To replace the semi colon character (;) with a newline, follow these exact steps.

1. locate cursor at upper left of buffer containing text you want to change
2. Type m-x replace-string and hit RETURN
3. the mini-buffer will display something like this: Replace string (default ^ -> ):
4. Type in the character you want to replace. In this case, ; and hit RETURN
5. the mini-buffer will display something like this: string ; with:
6. Now execute C-q C-j
7. All instances of semi-colon will be replaced a newline (from the cursor location to the end of the buffer will now appear)

Bit more to it than the original explanation says.

Something a bit more functional (easy to use anywhere):

function strip_carriage_returns($string)
{
    return str_replace(array("\n\r", "\n", "\r"), '', $string);
}

Using PHP_EOL as the search replacement parameter is also a good idea! Kudos.

You can use .is(':visible')

Selects all elements that are visible.

For example:

if($('#selectDiv').is(':visible')){

Also, you can get the div which is visible by:

$('div:visible').callYourFunction();

Live example:

console.log($('#selectDiv').is(':visible'));_x000D_
console.log($('#visibleDiv').is(':visible'));

#selectDiv {_x000D_
  display: none;  _x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<div id="selectDiv"></div>_x000D_
<div id="visibleDiv"></div>

Look at the import maybe you have a cycle dependency, this was in my case the error, using import {} from 'jasmine'; will fix the errors in the console and make the code compilable but not removes the root of devil (in my case the cycle dependency).

This is a psuedo way of doing it

IF (selectField1 = true) 
SELECT Field1 FROM Table
ELSE
SELECT Field2 FROM Table

Try:

$("#myTable").append("<tr><%= escape_javascript( render :partial => name_of_partial ) %></tr>");

And in the partial, you should have:

<td>row1</td>
<td>row2</td>

# Copy the certificate into the directory Java_home\Jre\Lib\Security

changeit is the default truststore password

Have you taken a look at Response.js? It's designed for this kind of thing. Combine Response.band and Response.resize.

http://responsejs.com/

Response.resize(function() {
    if ( Response.band(1200) )
    {
       // 1200+
    }    
    else if ( Response.band(992) )
    {
        // 992+
    }
    else if ( Response.band(768) )
    {
        // 768+
    }
    else 
    {
        // 0->768
    }
});

Use this query to create the new table with the values from existing table

CREATE TABLE New_Table_name AS SELECT * FROM Existing_table_Name; 

Now you can get all the values from existing table into newly created table.

The argument to remove() is a filter document, so passing in an empty document means 'remove all':

db.user.remove({})

However, if you definitely want to remove everything you might be better off dropping the collection. Though that probably depends on whether you have user defined indexes on the collection i.e. whether the cost of preparing the collection after dropping it outweighs the longer duration of the remove() call vs the drop() call.

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

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

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

I know this is old, but I was able to accomplish this with

viewToUse.setImageResource(0);

Doesn't seem like it should work, but I tried it on a whim, and it worked perfectly.

This is a late answer to an old question, but all other answers are missing the point, which is that .NET did not have generics until .NET 2.0 in 2005.

String is a reference type instead of a value type because it was of crucial importance for Microsoft to ensure that strings could be stored in the most efficient way in non-generic collections, such as System.Collections.ArrayList.

Storing a value-type in a non-generic collection requires a special conversion to the type object which is called boxing. When the CLR boxes a value type, it wraps the value inside a System.Object and stores it on the managed heap.

Reading the value from the collection requires the inverse operation which is called unboxing.

Both boxing and unboxing have non-negligible cost: boxing requires an additional allocation, unboxing requires type checking.

Some answers claim incorrectly that string could never have been implemented as a value type because its size is variable. Actually it is easy to implement string as a fixed-length data structure containing two fields: an integer for the length of the string, and a pointer to a char array. You can also use a Small String Optimization strategy on top of that.

If generics had existed from day one I guess having string as a value type would probably have been a better solution, with simpler semantics, better memory usage and better cache locality. A List<string> containing only small strings could have been a single contiguous block of memory.

Please think first of open/closed principle. The default methods in interfaces DO VIOLATE it. This is a bad feature in Java. It encourages bad design, bad architecture, low software quality. I would suggest to avoid using default methods completely.

Ask yourself a few questions: Why can't you put your methods to the abstract class? Would you need then more than one abstract class? Then think about what is your class responsible for. Are you sure all methods you are going to put to the single class really fulfill the same purpose? May be you will distinguish several purposes and will then split your class into several classes, for each purpose its own class.

Try: Window -> Preferences -> Android -> LogCat. Change field "Show logcat view if ..." the value "VERBOSE". It helped me.

Restarting the terminal also made the trick for me.

I was having same issue in centos 6.5

Finaly solution below worked for me

-go to http://dl.fedoraproject.org/pub/epel/6/x86_64/
-search for php-mcrypt(http://dl.fedoraproject.org/pub/epel/6/x86_64/php-mcrypt-5.3.3-3.el6.x86_64.rpm)
-execute wget http://dl.fedoraproject.org/pub/epel/6/x86_64/php-mcrypt-5.3.3-3.el6.x86_64.rpm
-rpm -ivh php-mcrypt-5.3.3-3.el6.x86_64.rpm

if there are any dependencies you can download same using http://dl.fedoraproject.org/pub/epel/6/x86_64/

You failed to specify the exact columns (data) to test for normality. Use this instead

shapiro.test(heisenberg$HWWIchg)

LinkedHashMap is precisely what you're looking for.

It is exactly like HashMap, except that when you iterate over it, it presents the items in the insertion order.

Why not just make the server return the names?

["Woodland Hills", "none", "Los Angeles", "Laguna Hills"]

Then create the <option> elements using JavaScript.

$.ajax({
    url:'suggest.html',
    type:'POST',
    data: 'q=' + str,
    dataType: 'json',
    success: function( json ) {
        $.each(json, function(i, value) {
            $('#myselect').append($('<option>').text(value).attr('value', value));
        });
    }
});

When I had to solve this problem, I created a hard-coded data dictionary to map between numbers and their associated words. For example, the following might represent a few entries in the dictionary:

{1, "one"}
{2, "two"}
{30, "thirty"}

You really only need to worry about mapping numbers in the 10^0 (1,2,3, etc.) and 10^1 (10,20,30) positions because once you get to 100, you simply have to know when to use words like hundred, thousand, million, etc. in combination with your map. For example, when you have a number like 3,240,123, you get: three million two hundred forty thousand one hundred twenty three.

After you build your map, you need to work through each digit in your number and figure out the appropriate nomenclature to go with it.

It is possible to use a handler to do this, even in MVC4. Here's an example from one i made earlier:

public class ImageHandler : IHttpHandler
{
    byte[] bytes;

    public void ProcessRequest(HttpContext context)
    {
        int param;
        if (int.TryParse(context.Request.QueryString["id"], out param))
        {
            using (var db = new MusicLibContext())
            {
                if (param == -1)
                {
                    bytes = File.ReadAllBytes(HttpContext.Current.Server.MapPath("~/Images/add.png"));

                    context.Response.ContentType = "image/png";
                }
                else
                {
                    var data = (from x in db.Images
                                where x.ImageID == (short)param
                                select x).FirstOrDefault();

                    bytes = data.ImageData;

                    context.Response.ContentType = "image/" + data.ImageFileType;
                }

                context.Response.Cache.SetCacheability(HttpCacheability.NoCache);
                context.Response.BinaryWrite(bytes);
                context.Response.Flush();
                context.Response.End();
            }
        }
        else
        {
            //image not found
        }
    }

    public bool IsReusable
    {
        get
        {
            return false;
        }
    }
}

In the view, i added the ID of the photo to the query string of the handler.

To create a new screen with the name foo, use

screen -S foo

Then to reattach it, run

screen -r foo  # or use -x, as in
screen -x foo  # for "Multi display mode" (see the man page)

What I have found best is a CSRF token and save it in the session for links where you need to verify the referrer.

So if you are generating a FB callback then it would look something like this:

$token = uniqid(mt_rand(), TRUE);
$_SESSION['token'] = $token;
$url = "http://example.com/index.php?token={$token}";

Then the index.php will look like this:

if(empty($_GET['token']) || $_GET['token'] !== $_SESSION['token'])
{
    show_404();
} 

//Continue with the rest of code

I do know of secure sites that do the equivalent of this for all their secure pages.

We can easily achieve this using flex. no need for background-image.

First of all realise it is impossible to completely prevent a video being downloaded, all you can do is make it more difficult. I.e. you hide the source of the video.

A web browser temporarily downloads the video in a buffer, so if could prevent download you would also be preventing the video being viewed as well.

You should also know that <1% of the total population of the world will be able to understand the source code making it rather safe anyway. That does not mean you should not hide it in the source as well - you should.

You should not disable right click, and even less you should display a message saying "You cannot save this video for copyright reasons. Sorry about that.". As suggested in this answer.

This can be very annoying and confusing for the user. Apart from that; if they disable JavaScript on their browser they will be able to right click and save anyway.

Here is a CSS trick you could use:

video {
    pointer-events: none;
}

CSS cannot be turned off in browser, protecting your video without actually disabling right click. However one problem is that controls cannot be enabled either, in other words they must be set to false. If you are going to inplament your own Play/Pause function or use an API that has buttons separate to the video tag then this is a feasible option.

controls also has a download button so using it is not such a good idea either.

Here is a JSFiddle example.

If you are going to disable right click using JavaScript then also store the source of the video in JavaScript as well. That way if the user disables JavaScript (allowing right click) the video will not load (it also hides the video source a little better).

From TxRegex answer:

<video oncontextmenu="return false;" controls>
    <source type="video/mp4" id="video">
</video>

Now add the video via JavaScript:

document.getElementById("video").src = "https://www.w3schools.com/html/mov_bbb.mp4";

Functional JSFiddle

Another way to prevent right click involves using the embed tag. This is does not however provide the controls to run the video so they would need to be inplamented in JavaScript:

<embed src="https://www.w3schools.com/html/mov_bbb.mp4"></embed>

timeObject.setSeconds(timeObject.getSeconds() + 10)

You need to use the event.target which is the element which originally triggered the event. The this in your example code refers to document.

In jQuery, that's...

$(document).click(function(event) {
    var text = $(event.target).text();
});

Without jQuery...

document.addEventListener('click', function(e) {
    e = e || window.event;
    var target = e.target || e.srcElement,
        text = target.textContent || target.innerText;   
}, false);

Also, ensure if you need to support < IE9 that you use attachEvent() instead of addEventListener().

Try this:

$objPHPExcel->getActiveSheet()->getRowDimension('1')->setRowHeight(40);

The command is date

To customise the output there are a myriad of options available, see date --help for a list.

For example, date '+%A %W %Y %X' gives Tuesday 34 2013 08:04:22 which is the name of the day of the week, the week number, the year and the time.

HTML :

<div id="myDiv">
    <form id="myForm">
    </form> 
</div>

jQuery :

var chbx='<input type="checkbox" id="Mumbai" name="Mumbai" value="Mumbai" />Mumbai<br /> <input type="checkbox" id=" Delhi" name=" Delhi" value=" Delhi" /> Delhi<br/><input type="checkbox" id=" Bangalore" name=" Bangalore" value=" Bangalore"/>Bangalore<br />';

$("#myDiv form#myForm").html(chbx);

//to insert dynamically created form 
$("#myDiv").html("<form id='dynamicForm'>" +chbx + "'</form>");

Demo

One way you can achieve this is setting display: inline-block; on the div. It is by default a block element, which will always fill the width it can fill (unless specifying width of course).

inline-block's only downside is that IE only supports it correctly from version 8. IE 6-7 only allows setting it on naturally inline elements, but there are hacks to solve this problem.

There are other options you have, you can either float it, or set position: absolute on it, but these also have other effects on layout, you need to decide which one fits your situation better.

Amiram Korach solution is indeed tidy. Here's an alternative for the sake of versatility.

var count = dtList.Count;
// Perform a reverse tracking.
for (var i = count - 1; i > -1; i--)
{
    if (dtList[i]==string.Empty) dtList.RemoveAt(i);
}
// Keep only the unique list items.
dtList = dtList.Distinct().ToList();

1.Update project

Right Click on your project maven > update project

2.Build project

Right Click on your project again. run as > Maven build

If you have not created a “Run configuration” yet, it will open a new configuration with some auto filled values.

You can change the name. "Base directory" will be a auto filled value for you. Keep it as it is. Give maven command to ”Goals” fields.

i.e, “clean install” for building purpose

Click apply

Click run.

3.Run project on tomcat

Right Click on your project again. run as > Run-Configuration. It will open Run-Configuration window for you.

Right Click on “Maven Build” from the right side column and Select “New”. It will open a blank configuration for you.

Change the name as you want. For the base directory field you can choose values using 3 buttons(workspace,FileSystem,Variables). You can also copy and paste the auto generated value from previously created Run-configuration. Give the Goals as “tomcat:run”. Click apply. Click run.

If you want to get more clear idea with snapshots use the following link.

I have 3 spinners

Spinner c_fruit=(Spinner) findViewById(R.id.fruits);
Spinner c_vegetable=(Spinner) findViewById(R.id.vegetables);
Spinner c_beverage=(Spinner) findViewById(R.id.beverages);

And also I have a Async-Tack class.

Here is my spinner loading code

RequestSend reqs_fruit = new RequestSend(this);
reqs_fruit.where="Get_fruit_List";
reqs_fruit.title="Loading fruit";
reqs_fruit.execute();

RequestSend reqs_vegetable = new RequestSend(this);
reqs_vegetable.where="Get_vegetable_List";
reqs_vegetable.title="Loading vegetable";
reqs_vegetable.execute();

RequestSend reqs_beverage = new RequestSend(this);
reqs_beverage.where="Get_beverage_List";
reqs_beverage.title="Loading beverage";
reqs_beverage.execute();

This is working perfectly. One by one my spinners loaded. I didn't user executeOnExecutor.

Even if fileno(FILE *) may return a file descriptor, be VERY careful not to bypass stdio's buffer. If there is buffer data (either read or unflushed write), reads/writes from the file descriptor might give you unexpected results.

To answer one of the side questions, to convert a file descriptor to a FILE pointer, use fdopen(3)

I use tabBarController and i have a few section in my tableview at every tab, so this is best solution for me.

extension UITableView {

    func scrollToTop(){

        for index in 0...numberOfSections - 1 {
            if numberOfSections > 0 && numberOfRows(inSection: index) > 0 {
                scrollToRow(at: IndexPath(row: 0, section: index), at: .top, animated: true)
                break
            }

            if index == numberOfSections - 1 {
                setContentOffset(.zero, animated: true)
                break
            }
        }

    }

}

Here's an alternative way of solving this. It uses a while loop but takes into consideration empty gaps between rows.

function getLastRow (column) {
  var iLastRow = ss.getActiveSheet().getMaxRows();
  var aValues = ss.getActiveSheet().getRange(column + ":" + column).getValues();
  var row = "";
  while(row == ""){
    row = aValues[iLastRow-1];
    iLastRow--;
  }
  return iLastRow;
}

Virtual Function Tables

Let's begin with some background on virtual function tables and how they work (source):

[20.3] What's the difference between how virtual and non-virtual member functions are called?

Non-virtual member functions are resolved statically. That is, the member function is selected statically (at compile-time) based on the type of the pointer (or reference) to the object.

In contrast, virtual member functions are resolved dynamically (at run-time). That is, the member function is selected dynamically (at run-time) based on the type of the object, not the type of the pointer/reference to that object. This is called "dynamic binding." Most compilers use some variant of the following technique: if the object has one or more virtual functions, the compiler puts a hidden pointer in the object called a "virtual-pointer" or "v-pointer." This v-pointer points to a global table called the "virtual-table" or "v-table."

The compiler creates a v-table for each class that has at least one virtual function. For example, if class Circle has virtual functions for draw() and move() and resize(), there would be exactly one v-table associated with class Circle, even if there were a gazillion Circle objects, and the v-pointer of each of those Circle objects would point to the Circle v-table. The v-table itself has pointers to each of the virtual functions in the class. For example, the Circle v-table would have three pointers: a pointer to Circle::draw(), a pointer to Circle::move(), and a pointer to Circle::resize().

During a dispatch of a virtual function, the run-time system follows the object's v-pointer to the class's v-table, then follows the appropriate slot in the v-table to the method code.

The space-cost overhead of the above technique is nominal: an extra pointer per object (but only for objects that will need to do dynamic binding), plus an extra pointer per method (but only for virtual methods). The time-cost overhead is also fairly nominal: compared to a normal function call, a virtual function call requires two extra fetches (one to get the value of the v-pointer, a second to get the address of the method). None of this runtime activity happens with non-virtual functions, since the compiler resolves non-virtual functions exclusively at compile-time based on the type of the pointer.

My problem, or how I came here

I'm attempting to use something like this now for a cubefile base class with templated optimized load functions which will be implemented differently for different types of cubes (some stored by pixel, some by image, etc).

Some code:

virtual void  LoadCube(UtpBipCube<float> &Cube,long LowerLeftRow=0,long LowerLeftColumn=0,
        long UpperRightRow=-1,long UpperRightColumn=-1,long LowerBand=0,long UpperBand=-1) = 0;
virtual void  LoadCube(UtpBipCube<short> &Cube, long LowerLeftRow=0,long LowerLeftColumn=0,
        long UpperRightRow=-1,long UpperRightColumn=-1,long LowerBand=0,long UpperBand=-1) = 0;
virtual void  LoadCube(UtpBipCube<unsigned short> &Cube, long LowerLeftRow=0,long LowerLeftColumn=0,
        long UpperRightRow=-1,long UpperRightColumn=-1,long LowerBand=0,long UpperBand=-1) = 0;

What I'd like it to be, but it won't compile due to a virtual templated combo:

template<class T>
    virtual void  LoadCube(UtpBipCube<T> &Cube,long LowerLeftRow=0,long LowerLeftColumn=0,
            long UpperRightRow=-1,long UpperRightColumn=-1,long LowerBand=0,long UpperBand=-1) = 0;

I ended up moving the template declaration to the class level. This solution would have forced programs to know about specific types of data they would read before they read them, which is unacceptable.

Solution

warning, this isn't very pretty but it allowed me to remove repetitive execution code

1) in the base class

Note that LoadAnyCube is not declared in the base class.

Here's another stack overflow answer with a work around: need a virtual template member workaround.

If you want to do it the dirty way, try this.

@SuppressWarnings("unchecked")
public ArrayList<String> convert(ArrayList<Object> a) {
   return (ArrayList) a;
}

Advantage: here you save time by not iterating over all objects.

Disadvantage: may produce a hole in your foot.

So, i present cmdmsg.bat.

The code is:

@echo off
echo WScript.Quit MsgBox(%1, vbYesNo) > #.vbs
cscript //nologo #.vbs
echo. >%ERRORLEVEL%.cm
del #.vbs
exit /b

And a example file:

@echo off 
cls 
call cmdmsg "hi select yes or no"

if exist "6.cm" call :yes
if exist "7.cm" call :no

:yes
cls
if exist "6.cm" del 6.cm
if exist "7.cm" del 7.cm
echo.
echo you selected yes
echo.
pause >nul
exit /b

:no
cls
if exist "6.cm" del 6.cm
if exist "7.cm" del 7.cm
echo.
echo aw man, you selected no
echo.
pause >nul
exit /b

Since none of the above solve my issue, I will post my solution

A plain vanilla strings way to do it without engaging the preg regex engine:

function remEntities($str) {
  if(substr_count($str, '&') && substr_count($str, ';')) {
    // Find amper
    $amp_pos = strpos($str, '&');
    //Find the ;
    $semi_pos = strpos($str, ';');
    // Only if the ; is after the &
    if($semi_pos > $amp_pos) {
      //is a HTML entity, try to remove
      $tmp = substr($str, 0, $amp_pos);
      $tmp = $tmp. substr($str, $semi_pos + 1, strlen($str));
      $str = $tmp;
      //Has another entity in it?
      if(substr_count($str, '&') && substr_count($str, ';'))
        $str = remEntities($tmp);
    }
  }
  return $str;
}

BiEntropy wont be the fastest way of computing entropy, but it is rigorous and builds upon Shannon Entropy in a well defined way. It has been tested in various fields including image related applications. It is implemented in Python on Github.

I came here to find out how to make VSCode (Mac OS) create a new window when a file or folder is opened and VSCode is already running. The same as GitHub Atom does. The answers above haven't answered my query, bit I've found answer myself so will share.

Setting: window.openFilesInNewWindow - if set to on, files will open in a new window. window.openFoldersInNewWindow - if set to on, folders will open in a new window.

Bonus to make it behave like Atom: Set window.newWindowDimensions to maximised.

And if you need to style your form elements according to it's state (modified/not modified) dynamically or to test whether some values has actually changed, you can use the following module, developed by myself: https://github.com/betsol/angular-input-modified

It adds additional properties and methods to the form and it's child elements. With it, you can test whether some element contains new data or even test if entire form has new unsaved data.

You can setup the following watch: $scope.$watch('myForm.modified', handler) and your handler will be called if some form elements actually contains new data or if it reversed to initial state.

Also, you can use modified property of individual form elements to actually reduce amount of data sent to a server via AJAX call. There is no need to send unchanged data.

As a bonus, you can revert your form to initial state via call to form's reset() method.

You can find the module's demo here: http://plnkr.co/edit/g2MDXv81OOBuGo6ORvdt?p=preview

Cheers!

Implement Comparable interface to Fruit.

public class Fruit implements Comparable<Fruit> {

It implements the method

@Override
    public int compareTo(Fruit fruit) {
        //write code here for compare name
    }

Then do call sort method

Collections.sort(fruitList);

If you install the application on your device via adb install you should look for the reinstall option which should be -r. So if you do adb install -r you should be able to install without uninstalling before.

I have adapted the script from Russ Cam (thank you, Russ Cam!) to my own needs: I needed to merge any columns that had the same value, not just empty cells.

This could be useful to someone else... Here is what I have come up with:

jQuery(document).ready(function() {

   jQuery('table.tblSimpleAgenda tr').each(function() {
    var tr = this;
    var counter = 0;
    var strLookupText = '';

    jQuery('td', tr).each(function(index, value) {
      var td = jQuery(this);

      if ((td.text() == strLookupText) || (td.text() == "")) {
        counter++;
        td.prev().attr('colSpan', '' + parseInt(counter + 1,10) + '').css({textAlign : 'center'});
        td.remove();
      }
      else {
        counter = 0;
      }

      // Sets the strLookupText variable to hold the current value. The next time in the loop the system will check the current value against the previous value.
      strLookupText = td.text();

    });

  });

});

One of the problems with a click-to-text link is solving the desktop scenario where no native texting app exists. A solution is to use Zipwhip's Click-to-Text button creator.

• On the desktop, they send you an actual real text message behind the scenes from the user's input.
• On iOS or Android you get the native texting functionality instead.

In Android the visual design is stored in XML files and each Activity is associated to a design.

setContentView(R.layout.main)

R means Resource

layout means design

main is the xml you have created under res->layout->main.xml

Whenever you want to change the current look of an Activity or when you move from one Activity to another, the new Activity must have a design to show. We call setContentView in onCreate with the desired design as argument.

The easiest way to do it in Python 3.5 and higher is:

>>> 'halo'.encode().hex()
'68616c6f'

If you manually enter a string into a Python Interpreter using the utf-8 characters, you can do it even faster by typing b before the string:

>>> b'halo'.hex()
'68616c6f'

Equivalent in Python 2.x:

>>> 'halo'.encode('hex')
'68616c6f'

Here is an answer based on that by Anubis (which is a better approach as it doesn't modify the headers for every request) but which is more equivalent to the code in the original question:

using Newtonsoft.Json;
...

var client = new HttpClient();
var httpRequestMessage = new HttpRequestMessage
    {
        Method = HttpMethod.Post,
        RequestUri = new Uri("https://api.clickatell.com/rest/message"),
        Headers = { 
            { HttpRequestHeader.Authorization.ToString(), "Bearer xxxxxxxxxxxxxxxxxxx" },
            { HttpRequestHeader.Accept.ToString(), "application/json" },
            { "X-Version", "1" }
        },
        Content = new StringContent(JsonConvert.SerializeObject(svm))
    };

var response = client.SendAsync(httpRequestMessage).Result;

I always use this in jQuery for disabling links

$("form a").attr("disabled", "disabled");

For me adding AppRoutingModule to my imports solved the problem.

    imports: [
     BrowserModule,
     AppRoutingModule,
     RouterModule.forRoot([
      {
        path: 'new-cmp',
        component: NewCmpComponent
      }
     ])
    ]

just stumbled across this question, while most of the methods above will work. I just want to add that you can use the Event Bus Library, especially in scenarios where the component (Activity or Fragment) has not been created, its good for all sizes of android projects and many use cases. I have personally used it in several projects i have on playstore.

The existing answers solve most cases. However, I ran into a case where I needed the content of the grid-cell to be overflow: visible. I solved it by absolutely positioning within a wrapper (not ideal, but the best I know), like this:

.month-grid {
  display: grid;
  grid-template: repeat(6, 1fr) / repeat(7, 1fr);
  background: #fff;
  grid-gap: 2px;  
}

.day-item-wrapper {
  position: relative;
}

.day-item {
  position: absolute;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  padding: 10px;

  background: rgba(0,0,0,0.1);
}

You can see the default value in Chrome in this link

int64_t g_used_idle_socket_timeout_s = 300 // 5 minutes

In Chrome, as far as I know, there isn't an easy way (as Firefox do) to change the timeout value.

I add custom commands to a environment evoked in a CMD after starting services... I haven't done it with postgres, but with Oracle:

#set up var with noop command
RUN export POST_START_CMDS=":"
RUN mkdir /scripts
ADD script.sql /scripts
CMD service oracle-xe start; $POST_START_CMDS; tail -f /var/log/dmesg

and start with

docker run -d ... -e POST_START_CMDS="su - oracle -c 'sqlplus @/scripts/script' " <image>

.

After struggling a lot while creating a low level utility to handle the post and get requests for my project, I decided to post my effort here. Much on the lines of accepted answer, here is a snippet for making http and https POST requests for sending JSON data.

const http = require("http")
const https = require("https")

// Request handler function
let postJSON = (options, postData, callback) => {

    // Serializing JSON
    post_data = JSON.stringify(postData)

    let port = options.port == 443 ? https : http

    // Callback function for the request
    let req = port.request(options, (res) => {
        let output = ''
        res.setEncoding('utf8')

        // Listener to receive data
        res.on('data', (chunk) => {
            output += chunk
        });

        // Listener for intializing callback after receiving complete response
        res.on('end', () => {
            let obj = JSON.parse(output)
            callback(res.statusCode, obj)
        });
    });

   // Handle any errors occurred while making request
    req.on('error', (err) => {
        //res.send('error: ' + err.message)
    });

    // Request is made here, with data as string or buffer
    req.write(post_data)
    // Ending the request
    req.end()
};

let callPost = () => {

    let data = {
        'name': 'Jon',
        'message': 'hello, world'
    }

    let options = {
        host: 'domain.name',       // Your domain name
        port: 443,                 // 443 for https and 80 for http
        path: '/path/to/resource', // Path for the request
        method: 'POST',            
        headers: {
            'Content-Type': 'application/json',
            'Content-Length': Buffer.byteLength(data)
        }
    }

    postJSON(options, data, (statusCode, result) => {
        // Handle response
        // Process the received data
    });

}

You should target the smallest, not the largest, supported pixel resolution by the devices your app can run on.

Say if there's an actual Mac computer that can run OS X 10.9 and has a native screen resolution of only 1280x720 then that's the resolution you should focus on. Any higher and your game won't correctly run on this device and you could as well remove that device from your supported devices list.

You can rely on upscaling to match larger screen sizes, but you can't rely on downscaling to preserve possibly important image details such as text or smaller game objects.

The next most important step is to pick a fitting aspect ratio, be it 4:3 or 16:9 or 16:10, that ideally is the native aspect ratio on most of the supported devices. Make sure your game only scales to fit on devices with a different aspect ratio.

You could scale to fill but then you must ensure that on all devices the cropped areas will not negatively impact gameplay or the use of the app in general (ie text or buttons outside the visible screen area). This will be harder to test as you'd actually have to have one of those devices or create a custom build that crops the view accordingly.

Alternatively you can design multiple versions of your game for specific and very common screen resolutions to provide the best game experience from 13" through 27" displays. Optimized designs for iMac (desktop) and a Macbook (notebook) devices make the most sense, it'll be harder to justify making optimized versions for 13" and 15" plus 21" and 27" screens.

But of course this depends a lot on the game. For example a tile-based world game could simply provide a larger viewing area onto the world on larger screen resolutions rather than scaling the view up. Provided that this does not alter gameplay, like giving the player an unfair advantage (specifically in multiplayer).

You should provide @2x images for the Retina Macbook Pro and future Retina Macs.

Your value:

this.element = $(id);

is a jQuery object, not a pure Canvas element.

To turn it back so you can call getContext(), call this.element.get(0), or better yet store the real element and not the jQuery object:

function canvasLayer(location, id) {

    this.width = $(window).width();
    this.height = $(window).height();
    this.element = document.createElement('canvas');

    $(this.element)
       .attr('id', id)
       .text('unsupported browser')
       .attr('width', this.width)       // for pixels
       .attr('height', this.height)
       .width(this.width)               // for CSS scaling
       .height(this.height)
       .appendTo(location);

    this.context = this.element.getContext("2d");
}

See running code at http://jsfiddle.net/alnitak/zbaMh/, ideally using the Chrome Javascript Console so you can see the resulting object in the debug output.

1 additional caveat (besides the answer by kanaka/peter): if you use WSS, and the server certificate is not acceptable to the browser, you may not get any browser rendered dialog (like it happens for Web pages). This is because WebSockets is treated as a so-called "subresource", and certificate accept / security exception / whatever dialogs are not rendered for subresources.

For those who are looking for PHP ( >5.3.5 ) PDO statement, we can set charset as per below:

$dbh = new PDO('mysql:host=localhost;dbname=testdb;charset=utf8', 'username', 'password');

This worked for me:

1. Login to your iphone provisioning portal through developer.apple.com
2. Add the UDID in devices
3. Go back to XCode, open up the Organizer and select "Provisioning Profiles", ensure that "Automatic Device Provisioning" is checked on the top right pane, then click on the "Refresh" button, and magically all your devices set in the provisioning portal will be automatically added.

The solution by tremendows worked well for me. However , file was not getting saved in Internet Explorer 10+ also. The below code worked for me for IE browser.

var file = new Blob(([data]), { type: 'application/pdf' });
if (window.navigator.msSaveOrOpenBlob) {
    navigator.msSaveBlob(file, 'fileName.pdf');
}

mod = a % b

This stores the result of a mod b in the variable mod.

And you are right, 15 mod 4 is 3, which is exactly what python returns:

>>> 15 % 4
3

a %= b is also valid.

You can use StringEscapeUtils from Apache Commons Logging utility or escape manually using code for each character.

In common case you have private access for fields, so you CAN'T use getFields in reflection. Instead of this you should use getDeclaredFields

So, firstly, you should be aware if your Column annotation has the runtime retention:

@Retention(RetentionPolicy.RUNTIME)
@interface Column {
}

After that you can do something like this:

for (Field f: MyClass.class.getDeclaredFields()) {
   Column column = f.getAnnotation(Column.class);
       // ...
}

Obviously, you would like to do something with field - set new value using annotation value:

Column annotation = f.getAnnotation(Column.class);
if (annotation != null) {
    new PropertyDescriptor(f.getName(), Column.class).getWriteMethod().invoke(
        object,
        myCoolProcessing(
            annotation.value()
        )
    );
}

So, full code can be looked like this:

for (Field f : MyClass.class.getDeclaredFields()) {
    Column annotation = f.getAnnotation(Column.class);
    if (annotation != null)
        new PropertyDescriptor(f.getName(), Column.class).getWriteMethod().invoke(
                object,
                myCoolProcessing(
                        annotation.value()
                )
        );
}

Here's one more answer that I've found to be pretty concise and doesn't use external packages:

import datetime as dt
import calendar

# Today, in `dt.date` type
day = dt.datetime.now().date()

one_year_delta = dt.timedelta(days=366 if ((day.month >= 3 and calendar.isleap(day.year+1)) or
                                            (day.month < 3 and calendar.isleap(day.year))) else 365)

# Add one year to the current date
print(day + one_year_delta)

I figured out I wasn't in the correct folder. I needed goto the folder I just cloned before I ran this command.

Hi I solved this problem by putting per Fragment into distinct layout.And I made just related Layout visible and made the others visibilities gone.

I mean:

<?xml version="1.0" encoding="utf-8"?>
 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:orientation="vertical"
 android:layout_width="fill_parent"
 android:layout_height="fill_parent">

                   android:text="Button1"></Button>
           <Button android:text="Button2"
                   android:id="@+id/button2"
                   android:layout_width="wrap_content"
                   android:layout_height="wrap_content"></Button>
           <Button android:text="Button3"
                   android:id="@+id/button3"
                   android:layout_width="wrap_content"
                   android:layout_height="wrap_content"></Button>
           <Button android:text="Button4"
                   android:id="@+id/button4"
                   android:layout_width="wrap_content"
                   android:layout_height="wrap_content"></Button>
   </LinearLayout>
   <LinearLayout android:layout_width="full_screen"
              android:layout_height="0dp"
              android:layout_weight="1"
              android:id="action_For_Button1"
              android:visibility="visible">
                    <Fragment android:layout_width="full_screen"

                              android:id="fragment1"
                                        .
                                        .
                                        .
             / >
     </LinearLayout>

     <LinearLayout android:layout_width="full_screen"
              android:layout_height="0dp"
              android:id="action_For_Button1"
              android:layout_weight="1"
              android:visibility="gone">
                       <Fragment android:layout_width="full_screen"
                                 android:layout_height="full_screen"
                                 android:id="fragment2"
                                           .
                                           .
                                           .
             / >
        </LinearLayout>
                     .
                     .
                     .
        </LinearLayout>

I assumed that you will open your page as button 1 is clicked.You can control your fragment's visibilities on click action.You can make related Layout visible and the others gone and by Fragment Manager you can take your fragment.This approach worked for me.And since view that has visibility:gone is invisible, and it doesn't take any space for layout purposes I think this approach does not cause any space problem.

P.S:I just tried to explain my solution code may have syntax mistakes or uncompleted structure.

public class camera_act extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_camera_act);
         ImageView imageView = findViewById(R.id.image);
        Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        startActivityForResult(intent,90);
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
        super.onActivityResult(requestCode,resultCode,data);
       Bitmap bitmap = data.getExtras.get("imageKey");
       imageView.setBitmapImage(bitmap);
            
        }
    }
}

This code will remove your whole cache of the application, You can check on app setting and open the app info and check the size of cache. Once you will use this code your cache size will be 0KB . So it and enjoy the clean cache.

 if (Build.VERSION_CODES.KITKAT <= Build.VERSION.SDK_INT) {
            ((ActivityManager) context.getSystemService(ACTIVITY_SERVICE))
                    .clearApplicationUserData();
            return;
        }

To check whether a certain field is valid, use:

$('#myField')[0].checkValidity(); // returns true/false

To check if the form is valid, use:

$('#myForm')[0].checkValidity(); // returns true/false

If you want to display the native error messages that some browsers have (such as Chrome), unfortunately the only way to do that is by submitting the form, like this:

var $myForm = $('#myForm');

if(! $myForm[0].checkValidity()) {
  // If the form is invalid, submit it. The form won't actually submit;
  // this will just cause the browser to display the native HTML5 error messages.
  $myForm.find(':submit').click();
}

Hope this helps. Keep in mind that HTML5 validation is not supported in all browsers.

For multiple lines the best way I find is to do this:

        IEnumerable<string> lines = new List<string>
        {
            string.Format("{{ line with formatting... {0} }}", id),
            "line 2",
            "line 3"
        };
        StringBuilder sb = new StringBuilder();
        foreach(var line in lines)
            sb.AppendLine(line);

In this way you don't have to clutter the screen with the Environment.NewLine or AppendLine() repeated multiple times. It will also be less error prone than having to remember to type them.

It's a good practice if you need them. It's also a good practice is they make sense, so future coders can understand what you're doing.

But generally, no it's not a good practice to attach 10 class names to an object because most likely whatever you're using them for, you could accomplish the same thing with far fewer classes. Probably just 1 or 2.

To qualify that statement, javascript plugins and scripts may append far more classnames to do whatever it is they're going to do. Modernizr for example appends anywhere from 5 - 25 classes to your body tag, and there's a very good reason for it. jQuery UI appends lots of classnames when you use one of the widgets in that library.

When you include a string literal in a query, you can enclose the string in either single or double quotes; Access' database engine will accept either. So double quotes will avoid the problem with a string which contains a single quote.

SELECT * FROM tblStudents WHERE [name] Like "Daniel O'Neal";

If you want to keep the single quotes around your string, you can double up the single quote within it, as mentioned in other answers.

SELECT * FROM tblStudents WHERE [name] Like 'Daniel O''Neal';

Notice the square brackets surrounding name. I used the brackets to lessen the chance of confusing the database engine because name is a reserved word.

It's not clear why you're using the Like comparison in your query. Based on what you've shown, this should work instead.

SELECT * FROM tblStudents WHERE [name] = "Daniel O'Neal";

I do not know whether you have solved this problem but I want to post my solution for those might ran into the same problem.

1. First, make sure that you have the "Includes" folder in your Project Explorer. If you do not have it, go to second step. If you have it, go to third step.

2. Second, Window -> Preferences-> C/C++- > Build >Environment: Create two environment variables:

   a) Name: C_INCLUDE_PATH Value: /usr/include

   b) Name: CPLUS_INCLUDE_PATH Value: /usr/include/c++

Go to Cygwin/usr/include/, if you cannot find folder "c++", copy it from \cygwin\lib\gcc\i686-pc-cygwin\X.X.X\include and Then restart your Eclipse.

3. Third, Right Click your project in Project Explorer -> Properties -> C/C++ General -> Paths and Symbols -> Includes -> Languages:GNU C++ If you can find some C++ folders in the "Include directories" then click Apply and OK. Change a bit your codes, and save it.

You will find there will be not symbol could not be resolved problems.

I documented my solution, hoping someone might get benefits.

Major Difference between Object and MAP with Example :

it's Order of iteration in loop, In Map it follows the order as it was set while creation whereas in OBJECT does not.

SEE: OBJECT

const obj = {};
obj.prop1 = "Foo";
obj.prop2 = "Bar";
obj['1'] = "day";
console.log(obj)

**OUTPUT: {1: "day", prop1: "Foo", prop2: "Bar"}**

MAP

    const myMap = new Map()
    // setting the values
    myMap.set("foo", "value associated with 'a string'")
    myMap.set("Bar", 'value associated with keyObj')
    myMap.set("1", 'value associated with keyFunc')

OUTPUT:
**1.    ?0: Array[2]
1.   0: "foo"
2.   1: "value associated with 'a string'"
2.  ?1: Array[2]
1.   0: "Bar"
2.   1: "value associated with keyObj"
3.  ?2: Array[2]
1.   0: "1"
2.   1: "value associated with keyFunc"**

You might want to look at setting up a jail.

Not sure if this is still extant but I'm guessing you need something like

((field Like "AA*") AND (field Not Like "BB*"))

You can specify custom headers in the MessageContract.

You can also use < endpoint> headers that are stored in the configuration file and will be copied allong in the header of all the messages sent by the client/service. This is usefull to add some static header easily.

After doing some search i got solution from android developer guide

PendingIntent contentIntent ;
Intent intent = new Intent(this,TestActivity.class);
intent.putExtra("extra","Test");
TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);

stackBuilder.addParentStack(ArticleDetailedActivity.class);

contentIntent = stackBuilder.getPendingIntent(0,PendingIntent.FLAG_UPDATE_CURRENT);

To Get Intent extra value in Test Activity class you need to write following code :

 Intent intent = getIntent();
 String extra = intent.getStringExtra("extra") ;

If you want to enable CORS without using filters or without config file just add

@CrossOrigin

to the top of your controller and it work.

Looks like you need the package from the installation media if you're you're offline (located at D:\sources\sxs) You could copy this to each machine that you require .NET 3.5 on (so technically you only need the installation media once to get the package) and get each machine to run the command:

Dism.exe /online /enable-feature /featurename:NetFX3 /All /Source:c:\dotnet35 /LimitAccess

There's a guide on MSDN.

Move doSomething definition outside of its class declaration and after B and also make add accessible to A by public-ing it or friend-ing it.

class B;

class A
{
    void doSomething(B * b);
};

class B
{
public:
    void add() {}
};

void A::doSomething(B * b)
{
    b->add();
}

Git 1.8.2 features a new option ,--remote, that will enable exactly this behavior. Running

git submodule update --rebase --remote

will fetch the latest changes from upstream in each submodule, rebase them, and check out the latest revision of the submodule. As the documentation puts it:

--remote

This option is only valid for the update command. Instead of using the superproject’s recorded SHA-1 to update the submodule, use the status of the submodule’s remote-tracking branch.

This is equivalent to running git pull in each submodule, which is generally exactly what you want.

(This was copied from this answer.)

What ever you do, don't use a for loop:

# Don't do this
for file in $(find . -name "*.txt")
do
    …code using "$file"
done

Three reasons:

• For the for loop to even start, the find must run to completion.
• If a file name has any whitespace (including space, tab or newline) in it, it will be treated as two separate names.
• Although now unlikely, you can overrun your command line buffer. Imagine if your command line buffer holds 32KB, and your for loop returns 40KB of text. That last 8KB will be dropped right off your for loop and you'll never know it.

Always use a while read construct:

find . -name "*.txt" -print0 | while read -d $'\0' file
do
    …code using "$file"
done

The loop will execute while the find command is executing. Plus, this command will work even if a file name is returned with whitespace in it. And, you won't overflow your command line buffer.

The -print0 will use the NULL as a file separator instead of a newline and the -d $'\0' will use NULL as the separator while reading.

Convert your x-axis data from text to datetime.datetime, use datetime.strptime:

>>> from datetime import datetime
>>> datetime.strptime("2012-may-31 19:00", "%Y-%b-%d %H:%M")
 datetime.datetime(2012, 5, 31, 19, 0)

This is an example of how to plot data once you have an array of datetimes:

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

x = np.array([datetime.datetime(2013, 9, 28, i, 0) for i in range(24)])
y = np.random.randint(100, size=x.shape)

plt.plot(x,y)
plt.show()

HTML5 introduced a file upload api that allows you to monitor the progress of file uploads but for older browsers there's plupload a framework that specifically made to monitor file uploads and give information about them. plus it has plenty of callbacks so it can work across all browsers

They are implemented in very different ways.

hash_map (unordered_map in TR1 and Boost; use those instead) use a hash table where the key is hashed to a slot in the table and the value is stored in a list tied to that key.

map is implemented as a balanced binary search tree (usually a red/black tree).

An unordered_map should give slightly better performance for accessing known elements of the collection, but a map will have additional useful characteristics (e.g. it is stored in sorted order, which allows traversal from start to finish). unordered_map will be faster on insert and delete than a map.

You can create a function that returns a boolean value and checks every attribute. You can call that function to do the job for you.

Alternatively, you can initialize the object with default values. That way there is no need for you to do any checking.

I think you need to include only these options in build.gradle:

packagingOptions {
        exclude 'META-INF/DEPENDENCIES'
        exclude 'META-INF/NOTICE'
        exclude 'META-INF/LICENSE'
    }

p.s same answer from my post in : Error :: duplicate files during packaging of APK

I ran into the same problem, and I'm not sure why, but it turned out to be that the script link generated by Scripts.Render did not have a .js extension. Because it also does not have a Type attribute the browser was just unable to use it (chrome and firefox).

To resolve this, I changed my bundle configuration to generate compiled files with a js extension, e.g.

            var coreScripts = new ScriptBundle("~/bundles/coreAssets.js")
            .Include("~/scripts/jquery.js");

        var coreStyles = new StyleBundle("~/bundles/coreStyles.css")
            .Include("~/css/bootstrap.css");

Notice in new StyleBundle(... instead of saying ~/bundles/someBundle, I am saying ~/bundlers/someBundle.js or ~/bundles/someStyles.css..

This causes the link generated in the src attribute to have .js or .css on it when optimizations are enabled, as such the browsers know based on the file extension what mime/type to use on the get request and everything works.

If I take off the extension, everything breaks. That's because @Scripts and @Styles doesn't render all the necessary attributes to understand a src to a file with no extension.

I will repeat what the others said, but will just try to make it simpler...

First, just create the Interface class

public interface PostTaskListener<K> {
    // K is the type of the result object of the async task 
    void onPostTask(K result);
}

Second, create the AsyncTask (which can be an inner static class of your activity or fragment) that uses the Interface, by including a concrete class. In the example, the PostTaskListener is parameterized with String, which means it expects a String class as a result of the async task.

public static class LoadData extends AsyncTask<Void, Void, String> {

    private PostTaskListener<String> postTaskListener;

    protected LoadData(PostTaskListener<String> postTaskListener){
        this.postTaskListener = postTaskListener;
    }

    @Override
    protected void onPostExecute(String result) {
        super.onPostExecute(result);

        if (result != null && postTaskListener != null)
            postTaskListener.onPostTask(result);
    }
}

Finally, the part where your combine your logic. In your activity / fragment, create the PostTaskListener and pass it to the async task. Here is an example:

...
PostTaskListener<String> postTaskListener = new PostTaskListener<String>() {
    @Override
    public void onPostTask(String result) {
        //Your post execution task code
    }
}

// Create the async task and pass it the post task listener.
new LoadData(postTaskListener);

Done!

THIRD VERSION OF MY ANSWER:

Here's a multiple line example of inline Jade Javascript. I don't think you can write it without using a -. This is a flash message example that I use in a partial. Hope this helps!

-if(typeof(info) !== 'undefined')
  -if (info)
    - if(info.length){
      ul
        -info.forEach(function(info){
          li= info
      -})
  -}

Is the code you're trying to get to compile the code in your question?

If so, you don't need two things: first, you don't need to declare that it's Javascript/a script, you can just started coding after typing -; second, after you type -if you don't need to type the { or } either. That's what makes Jade pretty sweet.

--------------ORIGINAL ANSWER BELOW ---------------

Try prepending if with -:

-if(10 == 10)
  //do whatever you want here as long as it's indented two spaces from
   the `-` above

There are also tons of Jade examples at:

https://github.com/visionmedia/jade/blob/master/examples/

I built an extension called Checkpoints, an alternative to Local History. Checkpoints has support for viewing history for all files (that has checkpoints) in the tree view, not just the currently active file. There are some other minor differences aswell, but overall they are pretty similar.

You can use JSON.stringify(object) with an object and I just wrote a function that'll recursively convert an array to an object, like this JSON.stringify(convArrToObj(array)), which is the following code (more detail can be found on this answer):

// Convert array to object
var convArrToObj = function(array){
    var thisEleObj = new Object();
    if(typeof array == "object"){
        for(var i in array){
            var thisEle = convArrToObj(array[i]);
            thisEleObj[i] = thisEle;
        }
    }else {
        thisEleObj = array;
    }
    return thisEleObj;
}

To make it more generic, you can override the JSON.stringify function and you won't have to worry about it again, to do this, just paste this at the top of your page:

// Modify JSON.stringify to allow recursive and single-level arrays
(function(){
    // Convert array to object
    var convArrToObj = function(array){
        var thisEleObj = new Object();
        if(typeof array == "object"){
            for(var i in array){
                var thisEle = convArrToObj(array[i]);
                thisEleObj[i] = thisEle;
            }
        }else {
            thisEleObj = array;
        }
        return thisEleObj;
    };
    var oldJSONStringify = JSON.stringify;
    JSON.stringify = function(input){
        return oldJSONStringify(convArrToObj(input));
    };
})();

And now JSON.stringify will accept arrays or objects! (link to jsFiddle with example)

Edit:

Here's another version that's a tad bit more efficient, although it may or may not be less reliable (not sure -- it depends on if JSON.stringify(array) always returns [], which I don't see much reason why it wouldn't, so this function should be better as it does a little less work when you use JSON.stringify with an object):

(function(){
    // Convert array to object
    var convArrToObj = function(array){
        var thisEleObj = new Object();
        if(typeof array == "object"){
            for(var i in array){
                var thisEle = convArrToObj(array[i]);
                thisEleObj[i] = thisEle;
            }
        }else {
            thisEleObj = array;
        }
        return thisEleObj;
    };
    var oldJSONStringify = JSON.stringify;
    JSON.stringify = function(input){
        if(oldJSONStringify(input) == '[]')
            return oldJSONStringify(convArrToObj(input));
        else
            return oldJSONStringify(input);
    };
})();

js Performance test here, via jsPerf

In it's simplest form you would use it like:

var html = _.template('<li><%= name %></li>', { name: 'John Smith' });
//html is now '<li>John Smith</li>'   

If you're going to be using a template a few times you'll want to compile it so it's faster:

var template = _.template('<li><%= name %></li>');

var html = [];
for (var key in names) {
    html += template({ name: names[i] });
}

console.log(html.join('')); //Outputs a string of <li> items

I personally prefer the Mustache style syntax. You can adjust the template token markers to use double curly braces:

_.templateSettings.interpolate = /\{\{(.+?)\}\}/g;

var template = _.template('<li>{{ name }}</li>');

Firstly import:-

import hashlib, uuid

Then change your code according to this in your method:

uname = request.form["uname"]
pwd=request.form["pwd"]
salt = hashlib.md5(pwd.encode())

Then pass this salt and uname in your database sql query, below login is a table name:

sql = "insert into login values ('"+uname+"','"+email+"','"+salt.hexdigest()+"')"

To clear your form, admitted that your form's elements values are saved in your state, you can map through your state like that :

  // clear all your form
  Object.keys(this.state).map((key, index) => {
      this.setState({[key] : ""});
   });

If your form is among other fields, you can simply insert them in a particular field of the state like that:

 state={ 
        form: {
        name:"",
        email:""}
      }

      // handle set in nested objects
      handleChange = (e) =>{ 
        e.preventDefault(); 

        const newState = Object.assign({}, this.state);
        newState.form[e.target.name] = e.target.value;
        this.setState(newState);
      }

      // submit and clear state in nested object 
      onSubmit = (e) =>{ 
        e.preventDefault(); 

       var form =   Object.assign({}, this.state.form);
       Object.keys(form).map((key, index) => {
          form[key] = "" ;
        });

       this.setState({form})
      } 

One of my colleagues noticed that most of the HttpClient methods all call SendAsync(HttpRequestMessage request, CancellationToken cancellationToken) under the hood, which is a virtual method off of HttpMessageInvoker:

So by far the easiest way to mock out HttpClient was to simply mock that particular method:

var mockClient = new Mock<HttpClient>();
mockClient.Setup(client => client.SendAsync(It.IsAny<HttpRequestMessage>(), It.IsAny<CancellationToken>())).ReturnsAsync(_mockResponse.Object);

and your code can call most (but not all) of the HttpClient class methods, including a regular

httpClient.SendAsync(req)

Check here to confirm https://github.com/dotnet/corefx/blob/master/src/System.Net.Http/src/System/Net/Http/HttpClient.cs

Do you can use ->stateless() before the ->redirect(). Then you dont need the session anymore.

For only vertical center

    <div style="text-align: left; position: relative;height: 56px;background-color: pink;">
        <div style="background-color: lightblue;position:absolute;top:50%;    transform: translateY(-50%);">test</div>
    </div>

I always do like this, it's a very short and easy code to center both horizontally and vertically

.center{
    position: absolute;
    top: 50%;
    left: 50%;
    transform: translate(-50%, -50%);
}

<div class="center">Hello Centered World!</div>

You need to use regular expressions to identify the unwanted characters. For the most easily readable code, you want the str_replace_all from the stringr package, though gsub from base R works just as well.

The exact regular expression depends upon what you are trying to do. You could just remove those specific characters that you gave in the question, but it's much easier to remove all punctuation characters.

x <- "a1~!@#$%^&*(){}_+:\"<>?,./;'[]-=" #or whatever
str_replace_all(x, "[[:punct:]]", " ")

(The base R equivalent is gsub("[[:punct:]]", " ", x).)

An alternative is to swap out all non-alphanumeric characters.

str_replace_all(x, "[^[:alnum:]]", " ")

Note that the definition of what constitutes a letter or a number or a punctuatution mark varies slightly depending upon your locale, so you may need to experiment a little to get exactly what you want.

The direct cast var ListOfY = (List<Y>)ListOfX is not possible because it would require co/contravariance of the List<T> type, and that just can't be guaranteed in every case. Please read on to see the solutions to this casting problem.

While it seems normal to be able to write code like this:

List<Animal> animals = (List<Animal>) mammalList;

because we can guarantee that every mammal will be an animal, this is obviously a mistake:

List<Mammal> mammals = (List<Mammal>) animalList;

since not every animal is a mammal.

However, using C# 3 and above, you can use

IEnumerable<Animal> animals = mammalList.Cast<Animal>();

that eases the casting a little. This is syntactically equivalent to your one-by-one adding code, as it uses an explicit cast to cast each Mammal in the list to an Animal, and will fail if the cast is not successfull.

If you like more control over the casting / conversion process, you could use the ConvertAll method of the List<T> class, which can use a supplied expression to convert the items. It has the added benifit that it returns a List, instead of IEnumerable, so no .ToList() is necessary.

List<object> o = new List<object>();
o.Add("one");
o.Add("two");
o.Add(3);

IEnumerable<string> s1 = o.Cast<string>(); //fails on the 3rd item
List<string> s2 = o.ConvertAll(x => x.ToString()); //succeeds

For an oneliner, on linux or cygwin, you need to do public key authentication on the host, otherwise ssh will be asking for password.

gunzip -c numbers.sql.gz | ssh user@host mysql --user=user_name --password=your_password db_name

Or do port forwarding and connect to the remote mysql using a "local" connection:

ssh -L some_port:host:local_mysql_port user@host

then do the mysql connection on your local machine to localhost:some_port.

The port forwarding will work from putty too, with the similar -L option or you can configure it from the settings panel, somewhere down on the tree.

In AAA style using the explicitly typed initializer idiom:

#include <chrono>
#include <iostream>

int main(){
  auto start = std::chrono::high_resolution_clock::now();
  // Code to time here...
  auto end = std::chrono::high_resolution_clock::now();

  auto dur = end - start;
  auto i_millis = std::chrono::duration_cast<std::chrono::milliseconds>(dur);
  auto f_secs = std::chrono::duration_cast<std::chrono::duration<float>>(dur);
  std::cout << i_millis.count() << '\n';
  std::cout << f_secs.count() << '\n';
}

For strings like that, for me the most comfortable way to do it is doubling the ' or ", as explained in the MySQL manual:

There are several ways to include quote characters within a string:

A “'” inside a string quoted with “'” may be written as “''”.

A “"” inside a string quoted with “"” may be written as “""”.

Precede the quote character by an escape character (“\”).

A “'” inside a string quoted with “"” needs no special treatment and need not be doubled or escaped. In the same way, “"” inside a

Strings quoted with “'” need no special treatment.

It is from http://dev.mysql.com/doc/refman/5.0/en/string-literals.html.

EcmaScript 2017 added special functions to string prototype for that. padStart and padEnd are two new methods available in JavaScript string prototype object. As their name implies, they allow for formatting a string by adding padding characters at the start or the end. (Not supported by IE11 and lower)

var mystr = "Doe";
mystr = mystr.padStart('John ');

Try adding multiDexEnabled true to your app build.gradle file.

 defaultConfig {
    multiDexEnabled true
}

EDIT:

Try Steve's answer first. In case it happens frequently or first step didn't help multiDexEnabled might help. For those who love to dig deeper here is couple similar issues (with more answers):

:app:dexDebug ExecException finished with non-zero exit value 2

Error:Execution failed for task ':app:dexDebug'. com.android.ide.common.process.ProcessException

As mentioned by others in this thread, don't forget to explicitly set the width and height attributes in the svg like so:

<svg id="some_id" data-name="some_name" xmlns="http://www.w3.org/2000/svg"
     viewBox="0 0 26 42"
     width="26px" height="42px">

if you don't do that no js manipulation can help you as gmaps will not have a frame of reference and always use a standard size.

I believe the async library will provide you a very elegant way to do this. While promises and callbacks can get a little hard to juggle with, async can give neat patterns to streamline your thought process. To run functions in serial, you would need to put them in an async waterfall. In async lingo, every function is called a task that takes some arguments and a callback; which is the next function in the sequence. The basic structure would look something like:

async.waterfall([
  // A list of functions
  function(callback){
      // Function no. 1 in sequence
      callback(null, arg);
  },
  function(arg, callback){
      // Function no. 2 in sequence
      callback(null);
  }
],    
function(err, results){
   // Optional final callback will get results for all prior functions
});

I've just tried to briefly explain the structure here. Read through the waterfall guide for more information, it's pretty well written.

just had the same question, and answered this way, if this could help.

select * 
from table
where start_date between '2012-01-01' and '2012-04-13'
or    end_date   between '2012-01-01' and '2012-04-13'

If you use explicit anchor names such as,

<a name="sectionLink"></a>
<h1>Section<h1>

then in css you can simply set

A[name] {
    padding-top:100px;
}

This will work as long as your HREF anchor tags don't also specify a NAME attribute

There seems to be a major mistake in almost all the current answers in that they show BOTH GET and POST data. Not ONLY POST data.

The issue with your code as the accepted answer mentioned is that you did not import the facade. This can imported by adding the following at the top:

use Request;

public function add_question(Request $request)
{
    return Request::post();
}

You can also use the global request method like so (mentioned by @Canaan Etai), with no import required:

request()->post();

However, a better approach to importing Request in a controller method is by dependency injection as mentioned in @shuvrow answer:

use Illuminate\Http\Request;

public function add_question(Request $request)
{
    return $request->post();
}

More information about DI can be found here:

• https://laravel.com/docs/5.6/container
• https://laravel.com/docs/5.6/controllers#dependency-injection-and-controllers

In either case, you should use:

// Show only POST data
$request->post(); // DI
request()->post(); // global method
Request::post(); // facade

// Show only GET data
$request->query(); // DI
request()->query(); // global method
Request::query(); // facade

// Show all data (i.e. both GET and POST data)
$request->all(); // DI
request()->all(); // global method
Request::all(); // facade

Parameters are key-value pairs that can appear inside URL path, and start with a semicolon character (;).

Query string appears after the path (if any) and starts with a question mark character (?).

Both parameters and query string contain key-value pairs.

In a GET request, parameters appear in the URL itself:

<scheme>://<username>:<password>@<host>:<port>/<path>;<parameters>?<query>#<fragment>

In a POST request, parameters can appear in the URL itself, but also in the datastream (as known as content).

Query string is always a part of the URL.

Parameters can be buried in form-data datastream when using POST method so they may not appear in the URL. Yes a POST request can define parameters as form data and in the URL, and this is not inconsistent because parameters can have several values.

I've found no explaination for this behavior so far. I guess it might be useful sometimes to "unhide" parameters from a POST request, or even let the code handling a GET request share some parts with the code handling a POST. Of course this can work only with server code supporting parameters in a URL.

Until you get better insights, I suggest you to use parameters only in form-data datastream of POST requests.

RFC 3986

The following query returns the median from a list of values in one column. It cannot be used as or along with an aggregate function, but you can still use it as a sub-query with a WHERE clause in the inner select.

SQL Server 2005+:

SELECT TOP 1 value from
(
    SELECT TOP 50 PERCENT value 
    FROM table_name 
    ORDER BY  value
)for_median
ORDER BY value DESC

As others have mentioned, use triple quotes ”””abc””” for multiline strings. Also, you can do this without having to call close() using the with keyword. For example:

# HTML String
html = """
<table border=1>
     <tr>
       <th>Number</th>
       <th>Square</th>
     </tr>
     <indent>
     <% for i in range(10): %>
       <tr>
         <td><%= i %></td>
         <td><%= i**2 %></td>
       </tr>
     </indent>
</table>
"""

# Write HTML String to file.html
with open("file.html", "w") as file:
    file.write(html)

See https://stackoverflow.com/a/11783672/2206251 for more details on the with keyword in Python.

sys.exc_info() returns a tuple with three values (type, value, traceback).

1. Here type gets the exception type of the Exception being handled
2. value is the arguments that are being passed to constructor of exception class
3. traceback contains the stack information like where the exception occurred etc.

For Example, In the following program

try:

    a = 1/0

except Exception,e:

    exc_tuple = sys.exc_info()

Now If we print the tuple the values will be this.

1. exc_tuple[0] value will be "ZeroDivisionError"
2. exc_tuple[1] value will be "integer division or modulo by zero" (String passed as parameter to the exception class)
3. exc_tuple[2] value will be "trackback object at (some memory address)"

The above details can also be fetched by simply printing the exception in string format.

print str(e)

JSAES is a powerful implementation of AES in JavaScript. http://point-at-infinity.org/jsaes/

Try This: It is working for me

ng generate component componentName --module=app.module

moment().format();                                // "2019-08-12T17:52:17-05:00" (ISO 8601, no fractional seconds)
moment().format("dddd, MMMM Do YYYY, h:mm:ss a"); // "Monday, August 12th 2019, 5:52:00 pm"
moment().format("ddd, hA");                       // "Mon, 5PM"

$('#submenu li').hover(function(){
    $('#carousel').css('backgroundPosition', newValue);
});

This will remove all the whitespaces from your String,

 VAR2="${VAR2//[[:space:]]/}"

/ replaces the first occurrence and // all occurrences of whitespaces in the string. I.e. all white spaces get replaced by – nothing

\a is the bell/alert character, which on some systems triggers a sound. \nnn, represents an arbitrary ASCII character in octal base. However, \0 is special in that it represents the null character no matter what.

To answer your original question, you could escape your '0' characters as well, as:

std::string ("\060\000\060", 3);

(since an ASCII '0' is 60 in octal)

The MSDN documentation has a pretty detailed article on this, as well cppreference

Turns out that I just have to convert @column name testName to all small letters, since it was initially in camel case.

Although I was not able to use the official answer, the question was able to help me solve my problem by letting me know what to investigate.

Change:

@Column(name="testName")
private String testName;

To:

@Column(name="testname")
private String testName;

You can configure your build.gradle file for proguard implementation. It can be at module level or the project level.

 buildTypes {

    debug {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'

    }

}

The configuration shown is for debug level but you can write you own build flavors like shown below inside buildTypes:

    myproductionbuild{
        minifyEnabled true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
    }

Better to have your debug with minifyEnabled false and productionbuild and other builds as minifyEnabled true.

Copy your proguard-rules.txt file in the root of your module or project folder like

$YOUR_PROJECT_DIR\YoutProject\yourmodule\proguard-rules.txt

You can change the name of your file as you want. After configuration use one of the three options available to generate your build as per the buildType

1. Go to gradle task in right panel and search for assembleRelease/assemble(#your_defined_buildtype) under module tasks

2. Go to Build Variant in Left Panel and select the build from drop down

3. Go to project root directory in File Explorer and open cmd/terminal and run

Linux ./gradlew assembleRelease or assemble(#your_defined_buildtype)

Windows gradlew assembleRelease or assemble(#your_defined_buildtype)

You can find apk in your module/build directory.

More about the configuration and proguard files location is available at the link

It rocks :)

The below code helps me:

• match is used for regex comparisons.

ui-router doesn't track the previous state once it transitions, but the event $stateChangeSuccess is broadcast on the $rootScope when the state changes.

You should be able to catch the prior state from that event (from is the state you're leaving):

$rootScope.$on('$stateChangeSuccess', function (ev, to, toParams, from, fromParams) {
   //assign the "from" parameter to something
});

In addition to all already said, you might need to add:

header("Content-Transfer-Encoding: UTF-8");

It's very useful when handling files with multiple languages in them, like people's names, or cities.

If you are running a bomebrew on OSX, I used the following to install it:

brew install php56-ssh2

That worked for me. I pulled it from here. There should also be Ubuntu and OSX using mac port as well.

Here is the correct solution using list comprehensions (they're backward in the question):

>>> join = lambda it: (y for x in it for y in x)
>>> list(join([[1,2],[3,4,5],[]]))
[1, 2, 3, 4, 5]

In your case it would be

[image for menuitem in list_of_menuitems for image in menuitem.image_set.all()]

or you could use join and say

join(menuitem.image_set.all() for menuitem in list_of_menuitems)

In either case, the gotcha was the nesting of the for loops.

thetalkingwalnut asks:

What are some good ways to convince the skeptical developers on the team of the value of Unit Testing?

Everyone here is going to pile on lots of reasons out of the blue why unit testing is good. However, I find that often the best way to convince someone of something is to listen to their argument and address it point by point. If you listen and help them verbalize their concerns, you can address each one and perhaps convert them to your point of view (or at the very least, leave them without a leg to stand on). Who knows? Perhaps they will convince you why unit tests aren't appropriate for your situation. Not likely, but possible. Perhaps if you post their arguments against unit tests, we can help identify the counterarguments.

It's important to listen to and understand both sides of the argument. If you try to adopt unit tests too zealously without regard to people's concerns, you'll end up with a religious war (and probably really worthless unit tests). If you adopt it slowly and start by applying it where you will see the most benefit for the least cost, you might be able to demonstrate the value of unit tests and have a better chance of convincing people. I realize this isn't as easy as it sounds - it usually requires some time and careful metrics to craft a convincing argument.

Unit tests are a tool, like any other, and should be applied in such a way that the benefits (catching bugs) outweigh the costs (the effort writing them). Don't use them if/where they don't make sense and remember that they are only part of your arsenal of tools (e.g. inspections, assertions, code analyzers, formal methods, etc). What I tell my developers is this:

1. They can skip writing a test for a method if they have a good argument why it isn't necessary (e.g. too simple to be worth it or too difficult to be worth it) and how the method will be otherwise verified (e.g. inspection, assertions, formal methods, interactive/integration tests). They need to consider that some verifications like inspections and formal proofs are done at a point in time and then need to be repeated every time the production code changes, whereas unit tests and assertions can be used as regression tests (written once and executed repeatedly thereafter). Sometimes I agree with them, but more often I will debate about whether a method is really too simple or too difficult to unit test.

   • If a developer argues that a method seems too simple to fail, isn't it worth taking the 60 seconds necessary to write up a simple 5-line unit test for it? These 5 lines of code will run every night (you do nightly builds, right?) for the next year or more and will be worth the effort if even just once it happens to catch a problem that may have taken 15 minutes or longer to identify and debug. Besides, writing the easy unit tests drives up the count of unit tests, which makes the developer look good.

   • On the other hand, if a developer argues that a method seems too difficult to unit test (not worth the significant effort required), perhaps that is a good indication that the method needs to be divided up or refactored to test the easy parts. Usually, these are methods that rely on unusual resources like singletons, the current time, or external resources like a database result set. These methods usually need to be refactored into a method that gets the resource (e.g. calls getTime()) and a method that takes the resource as a argument (e.g. takes the timestamp as a parameter). I let them skip testing the method that retrieves the resource and they instead write a unit test for the method that now takes the resource as a argument. Usually, this makes writing the unit test much simpler and therefore worthwhile to write.

2. The developer needs to draw a "line in the sand" in how comprehensive their unit tests should be. Later in development, whenever we find a bug, they should determine if more comprehensive unit tests would have caught the problem. If so and if such bugs crop up repeatedly, they need to move the "line" toward writing more comprehensive unit tests in the future (starting with adding or expanding the unit test for the current bug). They need to find the right balance.

Its important to realize the unit tests are not a silver bullet and there is such a thing as too much unit testing. At my workplace, whenever we do a lessons learned, I inevitably hear "we need to write more unit tests". Management nods in agreement because its been banged into their heads that "unit tests" == "good".

However, we need to understand the impact of "more unit tests". A developer can only write ~N lines of code a week and you need to figure out what percentage of that code should be unit test code vs production code. A lax workplace might have 10% of the code as unit tests and 90% of the code as production code, resulting in product with a lot of (albeit very buggy) features (think MS Word). On the other hand, a strict shop with 90% unit tests and 10% production code will have a rock solid product with very few features (think "vi"). You may never hear reports about the latter product crashing, but that likely has as much to do with the product not selling very well as much as it has to do with the quality of the code.

Worse yet, perhaps the only certainty in software development is that "change is inevitable". Assume the strict shop (90% unit tests/10% production code) creates a product that has exactly 2 features (assuming 5% of production code == 1 feature). If the customer comes along and changes 1 of the features, then that change trashes 50% of the code (45% of unit tests and 5% of the production code). The lax shop (10% unit tests/90% production code) has a product with 18 features, none of which work very well. Their customer completely revamps the requirements for 4 of their features. Even though the change is 4 times as large, only half as much of the code base gets trashed (~25% = ~4.4% unit tests + 20% of production code).

My point is that you have to communicate that you understand that balance between too little and too much unit testing - essentially that you've thought through both sides of the issue. If you can convince your peers and/or your management of that, you gain credibility and perhaps have a better chance of winning them over.

You cannot do this with standard LINQ operators because LINQ provides query, not update support.

But you can generate a new list and replace the old one.

var authorsList = GetAuthorList();

authorsList = authorsList.Where(a => a.FirstName != "Bob").ToList();

Or you could remove all items in authors in a second pass.

var authorsList = GetAuthorList();

var authors = authorsList.Where(a => a.FirstName == "Bob").ToList();

foreach (var author in authors)
{
    authorList.Remove(author);
}

A CLASSPATH entry is either a directory at the head of a package hierarchy of .class files, or a .jar file. If you're expecting ./lib to include all the .jar files in that directory, it won't. You have to name them explicitly.

While it is possible to combine the results, I would advise against doing so.

You have two fundamentally different types of queries that return a different number of rows, a different number of columns and different types of data. It would be best to leave it as it is - two separate queries.

There is always the old-fashioned way:

long startTime = System.nanoTime();
methodToTime();
long endTime = System.nanoTime();

long duration = (endTime - startTime);  //divide by 1000000 to get milliseconds.

You can use Newtonsoft.Json, it's a dependency of Microsoft.AspNet.Mvc.ModelBinding which is a dependency of Microsoft.AspNet.Mvc. So, you don't need to add a dependency in your project.json.

#using Newtonsoft.Json
....
JsonConvert.DeserializeObject(json);

Note, using a WebAPI controller you don't need to deal with JSON.

UPDATE ASP.Net Core 3.0

Json.NET has been removed from the ASP.NET Core 3.0 shared framework.

You can use the new JSON serializer layers on top of the high-performance Utf8JsonReader and Utf8JsonWriter. It deserializes objects from JSON and serializes objects to JSON. Memory allocations are kept minimal and includes support for reading and writing JSON with Stream asynchronously.

To get started, use the JsonSerializer class in the System.Text.Json.Serialization namespace. See the documentation for information and samples.

To use Json.NET in an ASP.NET Core 3.0 project:

• Add a package reference to Microsoft.AspNetCore.Mvc.NewtonsoftJson
• Update ConfigureServices to call AddNewtonsoftJson().

    services.AddMvc()
        .AddNewtonsoftJson();

Read Json.NET support in Migrate from ASP.NET Core 2.2 to 3.0 Preview 2 for more information.

If there is no selection, you can use the properties .selectionStart or .selectionEnd (with no selection they're equal).

var cursorPosition = $('#myTextarea').prop("selectionStart");

Note that this is not supported in older browsers, most notably IE8-. There you'll have to work with text ranges, but it's a complete frustration.

I believe there is a library somewhere which is dedicated to getting and setting selections/cursor positions in input elements, though. I can't recall its name, but there seem to be dozens on articles about this subject.

Most of the time @cer solution works but if in case its not working then try installing it in base R (NOT in R studio). As R studio runs base R executable in background so new package will be available in R studio as well. [my experience in macOS]
