The problem could also be that Apache can't find php.ini If you set PHPIniDir incorrectly. Mine was set to: PHPIniDir "c:/php7" But, the folder is actually just "php" The clue was viewing phpinfo() Which showed: Configuration File (php.ini) Path C:\windows

You can also strip each line and concatenate into a final string.

myfile = open("data.txt","r")
data = ""
lines = myfile.readlines()
for line in lines:
    data = data + line.strip();

This would also work out just fine.

The quick select algorithm can find the k-th smallest element of an array in linear (O(n)) running time. Here is an implementation in python:

import random

def partition(L, v):
    smaller = []
    bigger = []
    for val in L:
        if val < v: smaller += [val]
        if val > v: bigger += [val]
    return (smaller, [v], bigger)

def top_k(L, k):
    v = L[random.randrange(len(L))]
    (left, middle, right) = partition(L, v)
    # middle used below (in place of [v]) for clarity
    if len(left) == k:   return left
    if len(left)+1 == k: return left + middle
    if len(left) > k:    return top_k(left, k)
    return left + middle + top_k(right, k - len(left) - len(middle))

def median(L):
    n = len(L)
    l = top_k(L, n / 2 + 1)
    return max(l)

forever might be of interest to you. It will run your .js-File 24/7 with logging options. Here are two snippets from the help text:

[Long Running Process] The forever process will continue to run outputting log messages to the console. ex. forever -o out.log -e err.log my-script.js

and

[Daemon] The forever process will run as a daemon which will make the target process start in the background. This is extremely useful for remote starting simple node.js scripts without using nohup. It is recommended to run start with -o -l, & -e. ex. forever start -l forever.log -o out.log -e err.log my-daemon.js forever stop my-daemon.js

Visual Leak Detector (VLD) is a free, robust, open-source memory leak detection system for Visual C++.

When you run your program under the Visual Studio debugger, Visual Leak Detector will output a memory leak report at the end of your debugging session. The leak report includes the full call stack showing how any leaked memory blocks were allocated. Double-click on a line in the call stack to jump to that file and line in the editor window.

If you only have crash dumps, you can use the Windbg !heap -l command, it will detect leaked heap blocks. Better open the gflags option: “Create user mode stack trace database”, then you will see the memory allocation call stack.

For me this was to do with a constraint that I was removing at build time. Unticking Remove at build time fixed the issue, and I suspect the compiler had an issue determining the layout without it.

The error code will mention which Storyboard is causing the issue.

You can delay your code using setTimeout to execute after click

function changeLink(){
    setTimeout(function() {
        var link = document.getElementById("mylink");
        link.setAttribute('href', "http://facebook.com");
        document.getElementById("mylink").innerHTML = "facebook";
    }, 100);
}

Here is a very simplified explanation:

1. Your web browser downloads the web server's certificate, which contains the public key of the web server. This certificate is signed with the private key of a trusted certificate authority.

2. Your web browser comes installed with the public keys of all of the major certificate authorities. It uses this public key to verify that the web server's certificate was indeed signed by the trusted certificate authority.

3. The certificate contains the domain name and/or ip address of the web server. Your web browser confirms with the certificate authority that the address listed in the certificate is the one to which it has an open connection.

4. Your web browser generates a shared symmetric key which will be used to encrypt the HTTP traffic on this connection; this is much more efficient than using public/private key encryption for everything. Your browser encrypts the symmetric key with the public key of the web server then sends it back, thus ensuring that only the web server can decrypt it, since only the web server has its private key.

Note that the certificate authority (CA) is essential to preventing man-in-the-middle attacks. However, even an unsigned certificate will prevent someone from passively listening in on your encrypted traffic, since they have no way to gain access to your shared symmetric key.

I had the API 17 installed but that was not enough. What I really need installed is the "Android SDK Build-Tools 17".

You can locate your "Android SDK Build-Tools X" inside the first child, named "Tools", in the "Android SDK Manager".

For me the solutions of this Error very strange. It was the issue of port address of EndpointAddress. In Visual studio port address of your file (e.g. Service1.svc) and port address of your wcf project must be the same which you gives into EndpointAddress. Let me describe you this solution in detail.

There are two steps to check the port addresses.

1. In your WCF Project right click to your Service file (e.g. Service1.svc) -> than select View in browser now in your browser you have url like http://localhost:61122/Service1.svc so now note down your port address as a 61122

2. Righ click your wcf project -> than select Properties -> go to the Web Tab -> Now in Servers section -> select Use Visual Studio Development Server -> select Specific Port and give the port address which we have earlier find from our Service1.svc service. That is (61122).

Earlier I have different port address. After Specifying port address properly which I have given into EndpointAddress, my problem was solved.

I hope this might be solved your issue.

If you've exported the environment variable:

export demoPath=/usr/local/demo

you can simply refer to it by name in the makefile (make imports all the environment variables you have set):

DEMOPATH = ${demoPath}    # Or $(demoPath) if you prefer.

If you've not exported the environment variable, it is not accessible until you do export it, or unless you pass it explicitly on the command line:

make DEMOPATH="${demoPath}" …

If you are using a C shell derivative, substitute setenv demoPath /usr/local/demo for the export command.

It is because there is no default ROOT web application. When you create some web app and deploy it to Tomcat using Eclipse, then you will be able to access it with the URL in the form of

http://localhost:8080/YourWebAppName

where YourWebAppName is some name you give to your web app (the so called application context path).

Quote from Jetty Documentation Wiki (emphasis mine):

The context path is the prefix of a URL path that is used to select the web application to which an incoming request is routed. Typically a URL in a Java servlet server is of the format http://hostname.com/contextPath/servletPath/pathInfo, where each of the path elements may be zero or more / separated elements. If there is no context path, the context is referred to as the root context.

If you still want the default app which is accessed with the URL of the form

http://localhost:8080

or if you change the default 8080 port to 80, then just

http://localhost

i.e. without application context path read the following (quote from Tutorial: Installing Tomcat 7 and Using it with Eclipse, emphasis mine):

Copy the ROOT (default) Web app into Eclipse. Eclipse forgets to copy the default apps (ROOT, examples, docs, etc.) when it creates a Tomcat folder inside the Eclipse workspace. Go to C:\apache-tomcat-7.0.34\webapps and copy the ROOT folder. Then go to your Eclipse workspace, go to the .metadata folder, and search for "wtpwebapps". You should find something like C:\your-eclipse-workspace-location\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps (or .../tmp1/wtpwebapps if you already had another server registered in Eclipse). Go to the wtpwebapps folder and paste ROOT (say "yes" if asked if you want to merge/replace folders/files). Then reload http://localhost/ to see the Tomcat welcome page.

I like to use gitk name_of_file

This shows a nice list of the changes that happened to a file at each commit, instead of showing the changes to all the files. Makes it easier to track down something that happened.

How to export your Visual Studio Code extensions from the terminal. Here is git for that. Maybe this helps somebody.

How to export your Visual Studio Code extensions from the terminal

Note: Unix-like systems only.

1. Export your extensions to a shell file:

code --list-extensions | sed -e 's/^/code --install-extension /' > my_vscode_extensions.sh

2. Verify your extensions installer file:

less my_vscode_extesions.sh

Install your extensions (optional)

Run your my_vscode_extensions.sh using a Bash command:

bash my_vscode_extensions.sh

In bootstrap 4 use "autoHide : true"

$('#datepicker1').datepicker({
    autoHide: true,
    format: 'mm-yyyy',
    endDate: new Date()
});

Yes, here you can use LIMIT.

You can try it by the below query:

SELECT * FROM employee_list SORT BY salary DESC LIMIT 2

I would avoid to do a query for each entry.

if(is_array($EMailArr)){

    $sql = "INSERT INTO email_list (R_ID, EMAIL, NAME) values ";

    $valuesArr = array();
    foreach($EMailArr as $row){

        $R_ID = (int) $row['R_ID'];
        $email = mysql_real_escape_string( $row['email'] );
        $name = mysql_real_escape_string( $row['name'] );

        $valuesArr[] = "('$R_ID', '$email', '$name')";
    }

    $sql .= implode(',', $valuesArr);

    mysql_query($sql) or exit(mysql_error()); 
}

There is a Hidden helper alongside HiddenFor which lets you set the value.

@Html.Hidden("RequiredProperty", "default")

EDIT Based on the edit you've made to the question, you could do this, but I believe you're moving into territory where it will be cheaper and more effective, in the long run, to fight for making the code change. As has been said, even by yourself, the controller or view model should be setting the default.

This code:

<ul>
@{
        var stacks = new System.Diagnostics.StackTrace().GetFrames();
        foreach (var frame in stacks)
        {
            <li>@frame.GetMethod().Name - @frame.GetMethod().DeclaringType</li>
        }
}
</ul>

Will give output like this:

Execute - ASP._Page_Views_ViewDirectoryX__SubView_cshtml
ExecutePageHierarchy - System.Web.WebPages.WebPageBase
ExecutePageHierarchy - System.Web.Mvc.WebViewPage
ExecutePageHierarchy - System.Web.WebPages.WebPageBase
RenderView - System.Web.Mvc.RazorView
Render - System.Web.Mvc.BuildManagerCompiledView
RenderPartialInternal - System.Web.Mvc.HtmlHelper
RenderPartial - System.Web.Mvc.Html.RenderPartialExtensions
Execute - ASP._Page_Views_ViewDirectoryY__MainView_cshtml

So assuming the MVC framework will always go through the same stack, you can grab var frame = stacks[8]; and use the declaring type to determine who your parent view is, and then use that determination to set (or not) the default value. You could also walk the stack instead of directly grabbing [8] which would be safer but even less efficient.

For future Googlers i've a different approach to check if it's last element. It's similar to last lines in OP question.

This directly compares elements rather than just checking index numbers.

$yourset.each(function() {
    var $this = $(this);
    if($this[0] === $yourset.last()[0]) {
        //$this is the last one
    }
});

It means the text is stored as wchar_t characters rather than plain old char characters.

(I originally said it meant unicode. I was wrong about that. But it can be used for unicode.)

As the official document: As of 1.9, a string is only considered to be HTML if it starts with a less-than ("<") character. The Migrate plugin can be used to restore the pre-1.9 behavior.

If a string is known to be HTML but may start with arbitrary text that is not an HTML tag, pass it to jQuery.parseHTML() which will return an array of DOM nodes representing the markup. A jQuery collection can be created from this, for example: $($.parseHTML(htmlString)). This would be considered best practice when processing HTML templates for example. Simple uses of literal strings such as $("<p>Testing</p>").appendTo("body") are unaffected by this change.

I've found the answer from these two websites: Net Maniac and Aimred.

You need to have version > 0.8 of rake to use this technique

The normal rake task description is this:

desc 'Task Description'
task :task_name => [:depends_on_taskA, :depends_on_taskB] do
  #interesting things
end

To pass arguments, do three things:

1. Add the argument names after the task name, separated by commas.
2. Put the dependencies at the end using :needs => [...]
3. Place |t, args| after the do. (t is the object for this task)

To access the arguments in the script, use args.arg_name

desc 'Takes arguments task'
task :task_name, :display_value, :display_times, :needs => [:depends_on_taskA, :depends_on_taskB] do |t, args|
  args.display_times.to_i.times do
    puts args.display_value
  end
end

To call this task from the command line, pass it the arguments in []s

rake task_name['Hello',4]

will output

Hello
Hello
Hello
Hello

and if you want to call this task from another task, and pass it arguments, use invoke

task :caller do
  puts 'In Caller'
  Rake::Task[:task_name].invoke('hi',2)
end

then the command

rake caller

will output

In Caller
hi
hi

I haven't found a way to pass arguments as part of a dependency, as the following code breaks:

task :caller => :task_name['hi',2]' do
   puts 'In Caller'
end

This should not be difficult. When creating a cell for your table, add a UITextField object to the cell's content view

UITextField *txtField = [[UITextField alloc] initWithFrame....]
...
[cell.contentView addSubview:txtField]

Set the delegate of the UITextField as self (ie your viewcontroller) Give a tag to the text field so you can identify which textfield was edited in your delegate methods. The keyboard should pop up when the user taps the text field. I got it working like this. Hope it helps.

How about

(from k in myList
 where k.id > 35
 select k).ToList().ForEach(k => k.Name = "Banana");

int cores = Runtime.getRuntime().availableProcessors();

If cores is less than one, either your processor is about to die, or your JVM has a serious bug in it, or the universe is about to blow up.

if you are using Swift Mailer: please ensure that your $transport variable is similar to the below, based on tests i have done, that error results from ssl and port misconfiguration. note: you must include 'ssl' or 'tls' in the transport variable.

EXAMPLE CODE:

// Create the Transport
$transport = (new Swift_SmtpTransport('smtp.gmail.com', 465, 'ssl'))
  ->setUsername([email protected])
  ->setPassword(password)
;

// Create the Mailer using your created Transport
$mailer = new Swift_Mailer($transport);

// Create a message
$message = (new Swift_Message('News Letter Subscription'))
  ->setFrom(['[email protected]' => 'A Name'])
  ->setTo(['[email protected]' => 'A Name'])
  ->setBody('your message body')
  ;

// Send the message
$result = $mailer->send($message);

make sure you add {} around Html.RenderPartial, as:

@{Html.RenderPartial("FullName", new { firstName = model.FirstName, lastName = model.LastName});}

not

@Html.RenderPartial("FullName", new { firstName = model.FirstName, lastName = model.LastName});

Here is a small extension if you wish to insert at the beginning of the array without loosing the item at the first position

extension Array{
    mutating func appendAtBeginning(newItem : Element){
        let copy = self
        self = []
        self.append(newItem)
        self.appendContentsOf(copy)
    }
}

Fiddle : Demo

Read this thread R - boolean operators && and ||.

Basically, the & is vectorized, i.e. it acts on each element of the comparison returning a logical array with the same dimension as the input. && is not, returning a single logical.

Hide columns dynamically

The previous answers are using legacy DataTables syntax. In v 1.10+, you can use column().visible():

var dt = $('#example').DataTable();
//hide the first column
dt.column(0).visible(false);

To hide multiple columns, columns().visible() can be used:

var dt = $('#example').DataTable();
//hide the second and third columns
dt.columns([1,2]).visible(false);

Here is a Fiddle Demo.

Hide columns when the table is initialized

To hide columns when the table is initialized, you can use the columns option:

$('#example').DataTable( {
    'columns' : [
        null,
        //hide the second column
        {'visible' : false },
        null,
        //hide the fourth column
        {'visible' : false }
    ]
});

For the above method, you need to specify null for columns that should remain visible and have no other column options specified. Or, you can use columnDefs to target a specific column:

$('#example').DataTable( {
    'columnDefs' : [
        //hide the second & fourth column
        { 'visible': false, 'targets': [1,3] }
    ]
});

This does exist, but it's actually a feature of git log:

git log -p [--follow] [-1] <path>

Note that -p can also be used to show the inline diff from a single commit:

git log -p -1 <commit>

Options used:

• -p (also -u or --patch) is hidden deeeeeeeep in the git-log man page, and is actually a display option for git-diff. When used with log, it shows the patch that would be generated for each commit, along with the commit information—and hides commits that do not touch the specified <path>. (This behavior is described in the paragraph on --full-diff, which causes the full diff of each commit to be shown.)
• -1 shows just the most recent change to the specified file (-n 1 can be used instead of -1); otherwise, all non-zero diffs of that file are shown.
• --follow is required to see changes that occurred prior to a rename.

As far as I can tell, this is the only way to immediately see the last set of changes made to a file without using git log (or similar) to either count the number of intervening revisions or determine the hash of the commit.

To see older revisions changes, just scroll through the log, or specify a commit or tag from which to start the log. (Of course, specifying a commit or tag returns you to the original problem of figuring out what the correct commit or tag is.)

Credit where credit is due:

• I discovered log -p thanks to this answer.
• Credit to FranciscoPuga and this answer for showing me the --follow option.
• Credit to ChrisBetti for mentioning the -n 1 option and atatko for mentioning the -1 variant.
• Credit to sweaver2112 for getting me to actually read the documentation and figure out what -p "means" semantically.

Java SE 6 or Java EE 5 provides a method to do this now so there is no need for extra libraries.

The method is DatatypeConverter.parseHexBinary

In this case it can be used as follows:

String str = "9B7D2C34A366BF890C730641E6CECF6F";
byte[] bytes = DatatypeConverter.parseHexBinary(str);

The class also provides type conversions for many other formats that are generally used in XML.

To disable resizing completely:

textarea {
    resize: none;
}

To allow only vertical resizing:

textarea {
    resize: vertical;
}

To allow only horizontal resizing:

textarea {
    resize: horizontal;
}

Or you can limit size:

textarea {
    max-width: 100px; 
    max-height: 100px;
}

To limit size to parents width and/or height:

textarea {
    max-width: 100%; 
    max-height: 100%;
}

okay, you can do this in one line of code. you'll need json2.js for this (you probably already have.). the two json objects here are unparsed strings.

json1 = '[{"foo":"bar"},{"bar":"foo"},{"name":"craig"}]';

json2 = '[{"foo":"baz"},{"bar":"fob"},{"name":"george"}]';

concattedjson = JSON.stringify(JSON.parse(json1).concat(JSON.parse(json2)));

You can check if your string starts with http or https using the small function below.

function has_prefix($string, $prefix) {
   return substr($string, 0, strlen($prefix)) == $prefix;
}

$url   = 'http://www.google.com';
echo 'the url ' . (has_prefix($url, 'http://')  ? 'does' : 'does not') . ' start with http://';
echo 'the url ' . (has_prefix($url, 'https://') ? 'does' : 'does not') . ' start with https://';

When you compile and run the code, you should set the classpath options value. Just like the following:

javac -classpath .;sqlitejdbc-v056.jar Text.java

java -classpath .;sqlitejdbc-v056.jar Text

Please pay attention to "." and the sparate ";"(win, the linux is ":")

The easiest way would be to select Relativelayout from the Pallete, and then use it.

You just need a binary (with debugging symbols included) that is identical to the one that generated the core dump file. Then you can run gdb path/to/the/binary path/to/the/core/dump/file to debug it.

When it starts up, you can use bt (for backtrace) to get a stack trace from the time of the crash. In the backtrace, each function invocation is given a number. You can use frame number (replacing number with the corresponding number in the stack trace) to select a particular stack frame.

You can then use list to see code around that function, and info locals to see the local variables. You can also use print name_of_variable (replacing "name_of_variable" with a variable name) to see its value.

Typing help within GDB will give you a prompt that will let you see additional commands.

Since you are still getting duplicate using only UNION I would check that:

• That they are exact duplicates. I mean, if you make a

  SELECT DISTINCT * FROM (<your query>) AS subquery

  you do get fewer files?

• That you don't have already the duplicates in the first part of the query (maybe generated by the left join). As I understand it UNION it will not add to the result set rows that are already on it, but it won't remove duplicates already present in the first data set.

@Anachronist is closest here, @Simone not far off. The caveat with percentage padding on an element is that it's based on its parent's width, so if different to your container, the proportions will be off.

%__CD__% , %CD% , %=C:%

There's also another dynamic variable %__CD__% which points to the current directory but alike %CD% it has a backslash at the end. This can be useful if you want to append files to the current directory.

With %=C:% %=D:% you can access the last accessed directory for the corresponding drive. If the variable is not defined you haven't accessed the drive on the current cmd session.

And %__APPDIR__% expands to the executable that runs the current script a.k.a. cmd.exe directory.

 DataTable dt = new DataTable();
 dt.Load(reader);
 int numRows= dt.Rows.Count;

the simplest solution is.....open your website in vs2013 and go to Debug->WebsiteProperties (last option) a new window will open..

in this window go to "Build" option and change .net framework version from 4.5 to 4.0.....then select ok. [note: this step will only work if your project does not have dependencies with vs2013...]

Now open your website in vs2010

I retried an image from a URL and stored on my SD-card using the following code:

public String Downloadfromurl(String Url)
{

 String filepath=null;

 try {

  URL url = new URL(Url);

  //create the new connection

  HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();

  //set up some things on the connection
  urlConnection.setRequestMethod("GET");

  urlConnection.setDoOutput(true); 

   //and connect!

  urlConnection.connect();

  //set the path where we want to save the file
  //in this case, going to save it on the root directory of the
  //sd card.

  folder = new File(Environment.getExternalStorageDirectory().toString()+"/img");

  folder.mkdirs();

  //create a new file, specifying the path, and the filename
  //which we want to save the file as.

  String filename= "page"+no+".PNG";   

  file = new File(folder,filename);

  if(file.createNewFile())

  {

   file.createNewFile();

  }

  //this will be used to write the downloaded data into the file we created
  FileOutputStream fileOutput = new FileOutputStream(file);

  //this will be used in reading the data from the internet
  InputStream inputStream = urlConnection.getInputStream();

  //this is the total size of the file
  int totalSize = urlConnection.getContentLength();
  //variable to store total downloaded bytes
  int downloadedSize = 0;

  //create a buffer...
  byte[] buffer = new byte[1024];
  int bufferLength = 0; //used to store a temporary size of the buffer

  //now, read through the input buffer and write the contents to the file
  while ( (bufferLength = inputStream.read(buffer)) > 0 ) {
   //add the data in the buffer to the file in the file output stream (the file on the sd card
   fileOutput.write(buffer, 0, bufferLength);
   //add up the size so we know how much is downloaded

In Java int is a primitive data type while Integer is a Helper class, it is use to convert for one data type to other.

For example:

         double doubleValue = 156.5d;
         Double doubleObject  = new Double(doubleValue);
         Byte myByteValue = doubleObject.byteValue ();
         String myStringValue = doubleObject.toString();

Primitive data types are store the fastest available memory where the Helper class is complex and store in heap memory.

We can have two ways of calling the functions written in pgadmin for postgre sql database.

Suppose we have defined the function as below:

CREATE OR REPLACE FUNCTION helloWorld(name text) RETURNS void AS $helloWorld$
DECLARE
BEGIN
    RAISE LOG 'Hello, %', name;
END;
$helloWorld$ LANGUAGE plpgsql;

We can call the function helloworld in one of the following way:

SELECT "helloworld"('myname');

SELECT public.helloworld('myname')

Here are some density constants, source:

There are, in addition to the standard densities, 5 Intermediate ones. Taking into account this fact, the following code will be a complete working example:

float density = getResources().getDisplayMetrics().density;

if (density == 0.75f)
{
    // LDPI
}
else if (density >= 1.0f && density < 1.5f)
{
    // MDPI
}
else if (density == 1.5f)
{
    // HDPI
}
else if (density > 1.5f && density <= 2.0f)
{
    // XHDPI
}
else if (density > 2.0f && density <= 3.0f)
{
    // XXHDPI
}
else
{
    // XXXHDPI 
}

Alternatively, you can find density constants using the densityDpi:

int densityDpi = getResources().getDisplayMetrics().densityDpi;

switch (densityDpi)
{
    case DisplayMetrics.DENSITY_LOW:
        // LDPI
        break;

    case DisplayMetrics.DENSITY_MEDIUM:
        // MDPI
        break;

    case DisplayMetrics.DENSITY_TV:
    case DisplayMetrics.DENSITY_HIGH:
        // HDPI
        break;

    case DisplayMetrics.DENSITY_XHIGH:
    case DisplayMetrics.DENSITY_280:
        // XHDPI
        break;

    case DisplayMetrics.DENSITY_XXHIGH:
    case DisplayMetrics.DENSITY_360:
    case DisplayMetrics.DENSITY_400:
    case DisplayMetrics.DENSITY_420:
        // XXHDPI
        break;

    case DisplayMetrics.DENSITY_XXXHIGH:
    case DisplayMetrics.DENSITY_560:
        // XXXHDPI
        break;
}

Easiest method: Alt+Enter on

private static final long serialVersionUID = ;

IntelliJ will underline the space after the =. put your cursor on it and hit alt+Enter (Option+Enter on Mac). You'll get a popover that says "Randomly Change serialVersionUID Initializer". Just hit enter, and it'll populate that space with a random long.

All you have to do is wrap your content inside a Grid Container tag, specify the spacing, then wrap the actual content inside a Grid Item tag.

 <Grid container spacing={24}>
    <Grid item xs={8}>
      <leftHeaderContent/>
    </Grid>

    <Grid item xs={3}>
      <rightHeaderContent/>
    </Grid>
  </Grid>

Also, I've struggled with material grid a lot, I suggest you checkout flexbox which is built into CSS automatically and you don't need any addition packages to use. Its very easy to learn.

https://css-tricks.com/snippets/css/a-guide-to-flexbox/

Given this example url:

http://www.example.com/some-dir/yourpage.php?q=bogus&n=10

$_SERVER['REQUEST_URI'] will give you:

/some-dir/yourpage.php?q=bogus&n=10

Whereas $_GET['q'] will give you:

bogus

In other words, $_SERVER['REQUEST_URI'] will hold the full request path including the querystring. And $_GET['q'] will give you the value of parameter q in the querystring.

Slight modification of efnx clckclcks's javascript function. I changed the formatting from spaces to tab, but most importantly I allowed text to remain on one line:

var formatXml = this.formatXml = function (xml) {
        var reg = /(>)\s*(<)(\/*)/g; // updated Mar 30, 2015
        var wsexp = / *(.*) +\n/g;
        var contexp = /(<.+>)(.+\n)/g;
        xml = xml.replace(reg, '$1\n$2$3').replace(wsexp, '$1\n').replace(contexp, '$1\n$2');
        var pad = 0;
        var formatted = '';
        var lines = xml.split('\n');
        var indent = 0;
        var lastType = 'other';
        // 4 types of tags - single, closing, opening, other (text, doctype, comment) - 4*4 = 16 transitions 
        var transitions = {
            'single->single': 0,
            'single->closing': -1,
            'single->opening': 0,
            'single->other': 0,
            'closing->single': 0,
            'closing->closing': -1,
            'closing->opening': 0,
            'closing->other': 0,
            'opening->single': 1,
            'opening->closing': 0,
            'opening->opening': 1,
            'opening->other': 1,
            'other->single': 0,
            'other->closing': -1,
            'other->opening': 0,
            'other->other': 0
        };

        for (var i = 0; i < lines.length; i++) {
            var ln = lines[i];

            // Luca Viggiani 2017-07-03: handle optional <?xml ... ?> declaration
            if (ln.match(/\s*<\?xml/)) {
                formatted += ln + "\n";
                continue;
            }
            // ---

            var single = Boolean(ln.match(/<.+\/>/)); // is this line a single tag? ex. <br />
            var closing = Boolean(ln.match(/<\/.+>/)); // is this a closing tag? ex. </a>
            var opening = Boolean(ln.match(/<[^!].*>/)); // is this even a tag (that's not <!something>)
            var type = single ? 'single' : closing ? 'closing' : opening ? 'opening' : 'other';
            var fromTo = lastType + '->' + type;
            lastType = type;
            var padding = '';

            indent += transitions[fromTo];
            for (var j = 0; j < indent; j++) {
                padding += '\t';
            }
            if (fromTo == 'opening->closing')
                formatted = formatted.substr(0, formatted.length - 1) + ln + '\n'; // substr removes line break (\n) from prev loop
            else
                formatted += padding + ln + '\n';
        }

        return formatted;
    };

.uniq/.unique accepts a callback

var list = [{a:1,b:5},{a:1,c:5},{a:2},{a:3},{a:4},{a:3},{a:2}];

var uniqueList = _.uniq(list, function(item, key, a) { 
    return item.a;
});

// uniqueList = [Object {a=1, b=5}, Object {a=2}, Object {a=3}, Object {a=4}]

Notes:

1. Callback return value used for comparison
2. First comparison object with unique return value used as unique
3. underscorejs.org demonstrates no callback usage
4. lodash.com shows usage

Another example : using the callback to extract car makes, colors from a list

This might sound stupid and off topic but in my case I was using an external 4k Monitor with my MacBook Pro 13' (MacOS High Sierra, 2016) and I had the resolution set to the wrong scaled resolution. Switching to another scaled resolution where there was no "using a scaled resolution may affect performance" warning resolved my overall performance issues. In my case I had to increase the resolution to max.

So for me it was an overall performance problem which first surfaced with Android Studio, it was not an Android Studio specific problem.

EDIT 25.11.2017

As a result I had to increase font sizes in Android Studio:

and on my Mac in General. I followed some of these tips to get that done.

Use your bean class like this, if your JSON data starts with an an array object. it helps you.

Users[] bean = gson.fromJson(response,Users[].class);

Users is my bean class.

Response is my JSON data.

Perhaps you can use JavaScript to solve your cross-browser problem. It uses a different escape mechanism, one with which you're obviously already familiar:

(reference-to-the-tag).title = "Some \"text\"";

It doesn't strictly separate the functions of HTML, JavaScript, and CSS the way folks want you to nowadays, but whom do you need to make happy? Your users or techies you don't know?

Use filectime. For Windows it will return the creation time, and for Unix the change time which is the best you can get because on Unix there is no creation time (in most filesystems).

Note also that in some Unix texts the ctime of a file is referred to as being the creation time of the file. This is wrong. There is no creation time for Unix files in most Unix filesystems.

If you need to search many time in the same list, it may pay off to build an index.

Iterate once through, and build a HashMap with the equals value you are looking for as the key and the appropriate node as the value. If you need all instead of anyone of a given equals value, then let the map have a value type of list and build the whole list in the initial iteration.

Please note that you should measure before doing this as the overhead of building the index may overshadow just traversing until the expected node is found.

In modern browsers (IE8+, FF3.6+, Chrome), you can just listen to the hashchange event on window.

In some old browsers, you need a timer that continually checks location.hash. If you're using jQuery, there is a plugin that does exactly that.

Since Java 8 you can use the argument-less any method and the type argument will get inferred by the compiler:

verify(bar).doStuff(any());

Explanation

The new thing in Java 8 is that the target type of an expression will be used to infer type parameters of its sub-expressions. Before Java 8 only arguments to methods where used for type parameter inference (most of the time).

In this case the parameter type of doStuff will be the target type for any(), and the return value type of any() will get chosen to match that argument type.

This mechanism was added in Java 8 mainly to be able to compile lambda expressions, but it improves type inferences generally.

Primitive types

This doesn't work with primitive types, unfortunately:

public interface IBar {
    void doPrimitiveStuff(int i);
}

verify(bar).doPrimitiveStuff(any()); // Compiles but throws NullPointerException
verify(bar).doPrimitiveStuff(anyInt()); // This is what you have to do instead

The problem is that the compiler will infer Integer as the return value type of any(). Mockito will not be aware of this (due to type erasure) and return the default value for reference types, which is null. The runtime will try to unbox the return value by calling the intValue method on it before passing it to doStuff, and the exception gets thrown.

Perhaps the constructor of MDB2 has some code that uses a $variable =& new ClassName();

To replace commas with newline characters use this formula (assuming that the text to be altered is in cell A1):

=SUBSTITUTE(A1,",",CHAR(10))

You may have to then alter the row height to see all of the values in the cell

I've left a comment about the other part of your question

Edit: here's a screenshot of this working - I had to turn on "Wrap Text" in the "Format Cells" dialog.

You need to have your DBA modify the init.ora file, adding the directory you want to access to the 'utl_file_dir' parameter. Your database instance will then need to be stopped and restarted because init.ora is only read when the database is brought up.

You can view (but not change) this parameter by running the following query:

SELECT *
  FROM V$PARAMETER
  WHERE NAME = 'utl_file_dir'

Share and enjoy.

I followed the advice of several of the responses here to figure out what was wrong, but none of the answers seemed to explain how to fix it. My issue was that one reference required a different version of a second reference. So Newtonsoft was at version 6, but some other DLL wanted 4.5. Then I upgraded Newtonsoft as one of the other answers suggested and that made things worse.

So I actually downgraded my Newtonsoft install and the warning went away (VS 2017):

Right click References in the solution explorer and select Manage NuGet Packages... Under the "Installed" tab, find Newtonsoft (or whatever your conflict is) On the right side, a dropdown appears next to "Version" that you can change to older versions. It wasn't obvious to me that this dropdown could be used to downgrade.

Can't change the default browser, but try this (found online a while ago). Add a bookmark in Safari called "Open in Chrome" with the following.

javascript:location.href=%22googlechrome%22+location.href.substring(4);

Will open the current page in Chrome. Not as convenient, but maybe someone will find it useful.

Works for me.

In my case charset, datatype every thing was correct. After investigation I found that in parent table there was no index on foreign key column. Once added problem got solved.

I assume you know what a byte is. A byte array is simply an area of memory containing a group of contiguous (side by side) bytes, such that it makes sense to talk about them in order: the first byte, the second byte etc..

Just as bytes can encode different types and ranges of data (numbers from 0 to 255, numbers from -128 to 127, single characters using ASCII e.g. 'a' or '%', CPU op-codes), each byte in a byte array may be any of these things, or contribute to some multi-byte values such as numbers with larger range (e.g. 16-bit unsigned int from 0..65535), international character sets, textual strings ("hello"), or part/all of a compiled computer programs.

The crucial thing about a byte array is that it gives indexed (fast), precise, raw access to each 8-bit value being stored in that part of memory, and you can operate on those bytes to control every single bit. The bad thing is the computer just treats every entry as an independent 8-bit number - which may be what your program is dealing with, or you may prefer some powerful data-type such as a string that keeps track of its own length and grows as necessary, or a floating point number that lets you store say 3.14 without thinking about the bit-wise representation. As a data type, it is inefficient to insert or remove data near the start of a long array, as all the subsequent elements need to be shuffled to make or fill the gap created/required.

This should work:

ExeConfigurationFileMap fileMap = new ExeConfigurationFileMap();
Assembly asm = Assembly.GetCallingAssembly();
String path = Path.GetDirectoryName(new Uri(asm.EscapedCodeBase).LocalPath);

string strLog4NetConfigPath = System.IO.Path.Combine(path, "log4net.config");

I am using this to deploy DLL file libraries along with some configuration file (this is to use log4net from within the DLL file).

Also take a look at:

• http://wordlist.sourceforge.net/

It depends on the property type that you are parsing.

If the json property is a number (e.g. 5) you can cast to Long directly, so you could do:

(long) jsonObj.get("id") // with id = 5, cast `5` to long 

After getting the long,you could cast again to int, resulting in:

(int) (long) jsonObj.get("id")

If the json property is a number with quotes (e.g. "5"), is is considered a string, and you need to do something similar to Integer.parseInt() or Long.parseLong();

Integer.parseInt(jsonObj.get("id")) // with id = "5", convert "5" to Long

The only issue is, if you sometimes receive id's a string or as a number (you cant predict your client's format or it does it interchangeably), you might get an exception, especially if you use parseInt/Long on a null json object.

If not using Java Generics, the best way to deal with these runtime exceptions that I use is:

if(jsonObj.get("id") == null) {
   // do something here
}

int id;
try{
    id = Integer.parseInt(jsonObj.get("id").toString());
} catch(NumberFormatException e) {
  // handle here
}

You could also remove that first if and add the exception to the catch. Hope this helps.

As TStamper said, you can just apply the CSS class to it and design it that way. As CSS improves the number of things that you can do with links has become extraordinary, and there are design groups now that just focus on creating amazing-looking CSS buttons for themes, and so forth.

For example, you can transitions with background-color using the -webkit-transition property and pseduo-classes. Some of these designs can get quite nutty, but it's providing a fantastic alternative to what might in the past have had to have been done with, say, flash.

For example (these are mind-blowing in my opinion), http://tympanus.net/Development/CreativeButtons/ (this is a series of totally out-of-the-box animations for buttons, with source code on the originating page). http://www.commentredirect.com/make-awesome-flat-buttons-css/ (along the same lines, these buttons have nice but minimalistic transition effects, and they make use of the new "flat" design style.)

Try:

name = "^aH^ai"
name = name:gsub("%^a", "")

• UIApplication.setStatusBarX are deprecated as of iOS9
• It's deprecated to have UIViewControllerBasedStatusBarAppearance=NO in your info.plist
• So we should be using preferredStatusBarX in all our view controllers

But it gets more interesting when there's a UINavigationController involved:

• If navigationBarHidden = true, the child UIViewController's preferredStatusBarX are called, since the child is displaying the content under the status bar.
• If navigationBarHidden = false, the UINavigationController's preferredStatusBarX are called, after all it is displaying the content under the status bar.
• The UINavigationController's default preferredStatusBarStyle uses the value from UINav.navigationBar.barStyle. .Default = black status bar content, .Black = white status bar content.
• So if you're setting barTintColor to some custom colour (which you likely are), you also need to set barStyle to .Black to get white status bar content. I'd set barStyle to black before setting barTintColor, in case barStyle overrides the barTintColor.
• An alternative is that you can subclass UINavigationController rather than mucking around with bar style.
• HOWEVER, if you subclass UINavigationController, you get no control over the status bar if navigationBarHidden = true. Somehow UIKit goes direct to the child UIViewController without asking the UINavigationController in this situation. I would have thought it should be the UINavigationController's responsibility to ask the child >shrugs<.
• And modally displayed UIViewController's only get a say in the status bar if modalPresentationStyle = .FullScreen.
• If you've got a custom presentation style modal view controller and you really want it to control the status bar, you can set modalPresentationCapturesStatusBarAppearance = true.

You can try wrapping the option elements inside a span so that they wont be visible but still be loaded in the DOM. Like below

jQ('#ddlDropdown option').wrap('<span>');

And unwrap the option which contains the 'selected' attribute as follows to display already selected option.

var selectedOption = jQ('#ddlDropdown').find("[selected]");
jQ(selectedOption).unwrap();

This works across all the browsers.

You need to add a reference to System.Web.Extensions.dll in project for System.Web.Script.Serialization error.

You can solve it in two ways.

1. Make sure you put the CDN into the end of html page and place your own script after that. Example:

    <body>
      <div id="main">
        <div id="mainActivity" v-component="{{currentActivity}}" class="activity"></div>
      </div>
    </body>
    <script src="https://cdn.jsdelivr.net/npm/[email protected]"></script>
    <script src="js/app.js"></script>

where you need to put same javascript code you wrote in any other JavaScript file or in html file.

2. Use window.onload function in your JavaScript file.

Try deleting the virtualenv you created. Then create a new virtualenv with:

virtualenv flask

Then:

cd flask

Now let's activate the virtualenv

source bin/activate

Now you should see (flask) on the left of the command line.

_{Edit: In windows there is no "source" that's a linux thing, instead execute the activate.bat file, here I do it using Powershell: PS C:\DEV\aProject> & .\Flask\Scripts\activate)}

Let's install flask:

pip install flask

Then create a file named hello.py (NOTE: see UPDATE Flask 1.0.2 below):

from flask import Flask
app = Flask(__name__)

@app.route("/")
def hello():
    return "Hello World!"

if __name__ == "__main__":
    app.run()

and run it with:

python hello.py

UPDATE Flask 1.0.2

With the new flask release there is no need to run the app from your script. hello.py should look like this now:

from flask import Flask
app = Flask(__name__)

@app.route("/")
def hello():
    return "Hello World!"

and run it with:

FLASK_APP=hello.py flask run

Make sure to be inside the folder where hello.py is when running the latest command.

All the steps before the creation of the hello.py apply for this case as well

In Java side, the date is usually represented by the (poorly designed, but that aside) java.util.Date. It is basically backed by the Epoch time in flavor of a long, also known as a timestamp. It contains information about both the date and time parts. In Java, the precision is in milliseconds.

In SQL side, there are several standard date and time types, DATE, TIME and TIMESTAMP (at some DB's also called DATETIME), which are represented in JDBC as java.sql.Date, java.sql.Time and java.sql.Timestamp, all subclasses of java.util.Date. The precision is DB dependent, often in milliseconds like Java, but it can also be in seconds.

In contrary to java.util.Date, the java.sql.Date contains only information about the date part (year, month, day). The Time contains only information about the time part (hours, minutes, seconds) and the Timestamp contains information about the both parts, like as java.util.Date does.

The normal practice to store a timestamp in the DB (thus, java.util.Date in Java side and java.sql.Timestamp in JDBC side) is to use PreparedStatement#setTimestamp().

java.util.Date date = getItSomehow();
Timestamp timestamp = new Timestamp(date.getTime());
preparedStatement = connection.prepareStatement("SELECT * FROM tbl WHERE ts > ?");
preparedStatement.setTimestamp(1, timestamp);

The normal practice to obtain a timestamp from the DB is to use ResultSet#getTimestamp().

Timestamp timestamp = resultSet.getTimestamp("ts");
java.util.Date date = timestamp; // You can just upcast.

I realise this is a little late but you could add the following to your code. This won't work for transparent pngs though, you'd need a cropping mask for that. Which I'm now going to see about.

outerLink {
    overflow: hidden;
    position: relative;
}

outerLink:hover:after {
    background: #000;
    content: "";
    display: block;
    height: 100%;
    left: 0;
    opacity: 0.5;
    position: absolute;
    top: 0;
    width: 100%;
}

Try something like this:

try {
    $w = New-Object net.WebClient
    $d = $w.downloadString('http://foo')
}
catch [Net.WebException] {
    Write-Host $_.Exception.ToString()
}

The exception is in the $_ variable. You might explore $_ like this:

try {
    $w = New-Object net.WebClient
    $d = $w.downloadString('http://foo')
}
catch [Net.WebException] {
    $_ | fl * -Force
}

I think it will give you all the info you need.

My rule: if there is some data that is not displayed, try to use -force.

Your "workaround" (hiding the actionBar yourself) is the normal way. But google recommands to always hide the ActionBar when the TitleBar is hidden. Have a look here: https://developer.android.com/training/system-ui/status.html

@Christoph: just adding someting . i dont think so this is a correct way.to logout at both places at the same time.(<a href="/logout" onclick="FB.logout();">Logout</a>).

Just add id to the anchor tag . <a id='fbLogOut' href="/logout" onclick="FB.logout();">Logout</a>



$(document).ready(function(){

$('#fbLogOut').click(function(e){ 
     e.preventDefault();
      FB.logout(function(response) {
            // user is now logged out
            var url = $(this).attr('href');
            window.location= url;


        });
});});

Try following these steps:

1. Add the integratedSecurity=true to JDBC URL like this:

   Url: jdbc:sqlserver://<<Server>>:<<Port>>;databasename=<<DatabaseName>>;integratedsecurity=true 
   

2. Make sure to add the sqljdbc driver 4 or above version (sqljdbc.jar) in your project build path:

   java.sql.DatabaseMetaData metaData = connection.getMetaData();
   System.out.println("Driver version:" + metaData.getDriverVersion());
   

3. Add the VM argument for your project:

   • Find the sqljdbc_auth.dll file from DB installed server (C:\Program Files\sqljdbc_4.0\enu\auth\x86), or download from this link.

   • Place the dll file in your project folder and specify the VM argument like this: VM Argument: -Djava.library.path="<<DLL File path till folder>>"

     NOTE: Check your java version 32/64 bit then add 32/64 bit version dll file accordingly.

Your struct can have methods and properties... why not try

public struct MyStruct { 
    public string s;
    public int length { return s.Length; }
}

Correction @Guffa's answer shows that it is possible... more info here: http://www.codeproject.com/KB/cs/Csharp_implicit_operator.aspx

Have you seen the wiki pages on the zxing website? It seems you might find GettingStarted, DeveloperNotes and ScanningViaIntent helpful.

For Ruby programmers here is how you can assert. Have to include Minitest to get the asserts

    assert(@driver.find_element(:tag_name => "body").text.include?("Name"))

Square brackets are lists while parentheses are tuples.

A list is mutable, meaning you can change its contents:

>>> x = [1,2]
>>> x.append(3)
>>> x
[1, 2, 3]

while tuples are not:

>>> x = (1,2)
>>> x
(1, 2)
>>> x.append(3)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'tuple' object has no attribute 'append'

The other main difference is that a tuple is hashable, meaning that you can use it as a key to a dictionary, among other things. For example:

>>> x = (1,2)
>>> y = [1,2]
>>> z = {}
>>> z[x] = 3
>>> z
{(1, 2): 3}
>>> z[y] = 4
Traceback (most recent call last):

TypeError: unhashable type: 'list'

Note that, as many people have pointed out, you can add tuples together. For example:

>>> x = (1,2)
>>> x += (3,)
>>> x
(1, 2, 3)

However, this does not mean tuples are mutable. In the example above, a new tuple is constructed by adding together the two tuples as arguments. The original tuple is not modified. To demonstrate this, consider the following:

>>> x = (1,2)
>>> y = x
>>> x += (3,)
>>> x
(1, 2, 3)
>>> y
(1, 2)

Whereas, if you were to construct this same example with a list, y would also be updated:

>>> x = [1, 2]
>>> y = x
>>> x += [3]
>>> x
[1, 2, 3]
>>> y
[1, 2, 3]

I had the same problem because my "Dynamic Web Project" had no reference to the installed server i wanted to use and therefore had no reference to the Servlet API the server provides.

Following steps solved it without adding an extra Servlet-API to the Java Build Path (Eclipse version: Luna):

• Right click on your "Dynamic Web Project"
• Select Properties
• Select Project Facets in the list on the left side of the "Properties" wizard
• On the right side of the wizard you should see a tab named Runtimes. Select the Runtime tab and check the server you want to run the servlet.

Edit: if there is no server listed you can create a new one on the Runtimes tab

I had this today, and in my case the issue was very odd:

  <dependentAssembly>
    <assemblyIdentity name="Microsoft.Owin.Host.SystemWeb" publicKeyToken="31bf3856ad364e35" culture="neutral" />
    <bindingRedirect oldVersion="0.0.0.0-3.1.0" newVersion="3.1.0.0" />
  </dependentAssembly>0.

Note the stray characters at the end of the XML - somehow those had been moved from the version number to the end of this block of XML!

  <dependentAssembly>
    <assemblyIdentity name="Microsoft.Owin.Host.SystemWeb" publicKeyToken="31bf3856ad364e35" culture="neutral" />
    <bindingRedirect oldVersion="0.0.0.0-3.1.0.0" newVersion="3.1.0.0" />
  </dependentAssembly>

Changed to the above and voila! Everything worked again.

If structure is flat:

val df = Seq((1L, "a", "foo", 3.0)).toDF
df.printSchema
// root
//  |-- _1: long (nullable = false)
//  |-- _2: string (nullable = true)
//  |-- _3: string (nullable = true)
//  |-- _4: double (nullable = false)

the simplest thing you can do is to use toDF method:

val newNames = Seq("id", "x1", "x2", "x3")
val dfRenamed = df.toDF(newNames: _*)

dfRenamed.printSchema
// root
// |-- id: long (nullable = false)
// |-- x1: string (nullable = true)
// |-- x2: string (nullable = true)
// |-- x3: double (nullable = false)

If you want to rename individual columns you can use either select with alias:

df.select($"_1".alias("x1"))

which can be easily generalized to multiple columns:

val lookup = Map("_1" -> "foo", "_3" -> "bar")

df.select(df.columns.map(c => col(c).as(lookup.getOrElse(c, c))): _*)

or withColumnRenamed:

df.withColumnRenamed("_1", "x1")

which use with foldLeft to rename multiple columns:

lookup.foldLeft(df)((acc, ca) => acc.withColumnRenamed(ca._1, ca._2))

With nested structures (structs) one possible option is renaming by selecting a whole structure:

val nested = spark.read.json(sc.parallelize(Seq(
    """{"foobar": {"foo": {"bar": {"first": 1.0, "second": 2.0}}}, "id": 1}"""
)))

nested.printSchema
// root
//  |-- foobar: struct (nullable = true)
//  |    |-- foo: struct (nullable = true)
//  |    |    |-- bar: struct (nullable = true)
//  |    |    |    |-- first: double (nullable = true)
//  |    |    |    |-- second: double (nullable = true)
//  |-- id: long (nullable = true)

@transient val foobarRenamed = struct(
  struct(
    struct(
      $"foobar.foo.bar.first".as("x"), $"foobar.foo.bar.first".as("y")
    ).alias("point")
  ).alias("location")
).alias("record")

nested.select(foobarRenamed, $"id").printSchema
// root
//  |-- record: struct (nullable = false)
//  |    |-- location: struct (nullable = false)
//  |    |    |-- point: struct (nullable = false)
//  |    |    |    |-- x: double (nullable = true)
//  |    |    |    |-- y: double (nullable = true)
//  |-- id: long (nullable = true)

Note that it may affect nullability metadata. Another possibility is to rename by casting:

nested.select($"foobar".cast(
  "struct<location:struct<point:struct<x:double,y:double>>>"
).alias("record")).printSchema

// root
//  |-- record: struct (nullable = true)
//  |    |-- location: struct (nullable = true)
//  |    |    |-- point: struct (nullable = true)
//  |    |    |    |-- x: double (nullable = true)
//  |    |    |    |-- y: double (nullable = true)

or:

import org.apache.spark.sql.types._

nested.select($"foobar".cast(
  StructType(Seq(
    StructField("location", StructType(Seq(
      StructField("point", StructType(Seq(
        StructField("x", DoubleType), StructField("y", DoubleType)))))))))
).alias("record")).printSchema

// root
//  |-- record: struct (nullable = true)
//  |    |-- location: struct (nullable = true)
//  |    |    |-- point: struct (nullable = true)
//  |    |    |    |-- x: double (nullable = true)
//  |    |    |    |-- y: double (nullable = true)

If you need to actually get a File object, you could do the following:

URL url = this.getClass().getResource("/test.wsdl");
File testWsdl = new File(url.getFile());

Which has the benefit of working cross platform, as described in this blog post.

instead of

$('html, body').animate({scrollTop:xxx}, 'slow');

use

$('html, body').animate({scrollTop:$('#div_id').position().top}, 'slow');

this will return the absolute top position of whatever element you select as #div_id

you can check installed c# compilers and the printed version of the .net:

@echo off

for /r "%SystemRoot%\Microsoft.NET\Framework\" %%# in ("*csc.exe") do (
    set "l="
    for /f "skip=1 tokens=2 delims=k" %%$ in ('"%%# #"') do (
        if not defined l (
            echo Installed: %%$
            set l=%%$
        )
    )
)

echo latest installed .NET %l%

the csc.exe does not have a -version switch but it prints the .net version in its logo. You can also try with msbuild.exe but .net framework 1.* does not have msbuild.

You can always use iptables to delete the rules. If you have a lot of rules, just output them using the following command.

iptables-save > myfile

vi to edit them from the commend line. Just use the "dd" to delete the lines you no longer want.

iptables-restore < myfile and you're good to go.  

REMEMBER THAT IF YOU DON'T CONFIGURE YOUR OS TO SAVE THE RULES TO A FILE AND THEN LOAD THE FILE DURING THE BOOT THAT YOUR RULES WILL BE LOST.

You aren't doing anything with the return value of replace. You'll need to assign the result of the method, which is the new String:

sentence = sentence.replace("and", " ");

A String is immutable in java. Methods like replace return a new String.

Your contains test is unnecessary: replace will just no-op if there aren't instances of the text to replace.

A CASE statement is an expression, just like a boolean comparison. That means the 'AND' needs to go before the 'CASE' statement, not within it.:

Select * From Times
WHERE (StartDate <= @Date) AND (EndDate >= @Date)

AND -- Added the "AND" here

CASE WHEN @day = 'Monday' THEN (Monday = 1)   -- Removed "AND" 
    WHEN @day = 'Tuesday' THEN (Tuesday = 1)  -- Removed "AND" 
    ELSE AND (Wednesday = 1) 
END

theutz' answer here is very good, I just want to add this:

If you let your mapping profile inherit from MapperConfigurationExpression instead of Profile, you can very simply add a test to verify your mapping setup, which is always handy:

[Fact]
public void MappingProfile_VerifyMappings()
{
    var mappingProfile = new MappingProfile();

    var config = new MapperConfiguration(mappingProfile);
    var mapper = new Mapper(config);

    (mapper as IMapper).ConfigurationProvider.AssertConfigurationIsValid();
}

A - Solution

Speaking for C language, I've just found ampirically that following declaration code will be the solution;

typedef struct ListNode
{
    int data;
    ListNode * prev;
    ListNode * next;
} ListNode;

So as a general rule, I give the same name both for both type definition and name of the struct;

typedef struct X
{
    // code for additional types here
    X* prev; // reference to pointer
    X* next; // reference to pointer
} X;

B - Problemetic Samples

Where following declarations are considered both incomplete by the gcc compiler when executing following statement. ;

removed->next->prev = removed->prev;

And I get same error for the dereferencing code reported in the error output;

>gcc Main.c LinkedList.c -o Main.exe -w
LinkedList.c: In function 'removeFromList':
LinkedList.c:166:18: error: dereferencing pointer to incomplete type 'struct ListNode'
     removed->next->prev = removed->prev;

For both of the header file declarations listed below;

typedef struct
{
    int data;
    ListNode * prev;
    ListNode * next;
} ListNode;

Plus this one;

typedef struct ListNodeType
{
    int data;
    ListNode * prev;
    ListNode * next;
} ListNode;

I think this is what you were looking for:

grep -E "string1|string2" filename

I think that answers like this:

grep 'string1.*string2\|string2.*string1' filename

only match the case where both are present, not one or the other or both.

Various NPM packages are available to make this task easy.

For Development

• nodemon: most popular and actively maintained
• forever: second-most popular
• node-dev: actively maintained (as of Oct 2020)
• supervisor: no longer maintained

For Production (with extended functionality such as clustering, remote deploy etc.)

• pm2: npm install -g pm2
• Strong Loop Process Manager: npm install -g strongloop

Comparison between Forever, pm2 and StrongLoop can be found on StrongLoop's website.

Try:

mmatrix = np.zeros((nrows, ncols))

Since the shape parameter has to be an int or sequence of ints

http://docs.scipy.org/doc/numpy/reference/generated/numpy.zeros.html

Otherwise you are passing ncols to np.zeros as the dtype.

You cannot (except the type of a particular iterator implements some specific methods that make it possible).

Generally, you may count iterator items only by consuming the iterator. One of probably the most efficient ways:

import itertools
from collections import deque

def count_iter_items(iterable):
    """
    Consume an iterable not reading it into memory; return the number of items.
    """
    counter = itertools.count()
    deque(itertools.izip(iterable, counter), maxlen=0)  # (consume at C speed)
    return next(counter)

(For Python 3.x replace itertools.izip with zip).

For future visitors: In the new HttpClient (Angular 4.3+), the response object is JSON by default, so you don't need to do response.json().data anymore. Just use response directly.

Example (modified from the official documentation):

import { HttpClient } from '@angular/common/http';

@Component(...)
export class YourComponent implements OnInit {

  // Inject HttpClient into your component or service.
  constructor(private http: HttpClient) {}

  ngOnInit(): void {
    this.http.get('https://api.github.com/users')
        .subscribe(response => console.log(response));
  }
}

Don't forget to import it and include the module under imports in your project's app.module.ts:

...
import { HttpClientModule } from '@angular/common/http';

@NgModule({
  imports: [
    BrowserModule,
    // Include it under 'imports' in your application module after BrowserModule.
    HttpClientModule,
    ...
  ],
  ...

in iOS Simulator menu, go to Debug -> Location -> Custom Location. There you can set the latitude and longitude and test the app accordingly. This works with mapkit and also with CLLocationManager.

This is a good exercise for yourself to work on :)

You should break your library into three parts

• Loading the CSV file
• Representing the file in memory so that you can modify it and read it
• Saving the CSV file back to disk

So you are looking at writing a CSVDocument class that contains:

• Load(const char* file);
• Save(const char* file);
• GetBody

So that you may use your library like this:

CSVDocument doc;
doc.Load("file.csv");
CSVDocumentBody* body = doc.GetBody();

CSVDocumentRow* header = body->GetRow(0);
for (int i = 0; i < header->GetFieldCount(); i++)
{
    CSVDocumentField* col = header->GetField(i);
    cout << col->GetText() << "\t";
}

for (int i = 1; i < body->GetRowCount(); i++) // i = 1 so we skip the header
{
    CSVDocumentRow* row = body->GetRow(i);
    for (int p = 0; p < row->GetFieldCount(); p++)
    {
        cout << row->GetField(p)->GetText() << "\t";
    }
    cout << "\n";
}

body->GetRecord(10)->SetText("hello world");

CSVDocumentRow* lastRow = body->AddRow();
lastRow->AddField()->SetText("Hey there");
lastRow->AddField()->SetText("Hey there column 2");

doc->Save("file.csv");

Which gives us the following interfaces:

class CSVDocument
{
public:
    void Load(const char* file);
    void Save(const char* file);

    CSVDocumentBody* GetBody();
};

class CSVDocumentBody
{
public:
    int GetRowCount();
    CSVDocumentRow* GetRow(int index);
    CSVDocumentRow* AddRow();
};

class CSVDocumentRow
{
public:
    int GetFieldCount();
    CSVDocumentField* GetField(int index);
    CSVDocumentField* AddField(int index);
};

class CSVDocumentField
{
public:
    const char* GetText();
    void GetText(const char* text);
};

Now you just have to fill in the blanks from here :)

Believe me when I say this - investing your time into learning how to make libraries, especially those dealing with the loading, manipulation and saving of data, will not only remove your dependence on the existence of such libraries but will also make you an all-around better programmer.

:)

EDIT

I don't know how much you already know about string manipulation and parsing; so if you get stuck I would be happy to help.

Try using setAttribute instead:

document.getElementById('img')
    .setAttribute(
        'src', 'data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg=='
    );

Real answer: (And make sure you remove the line-breaks in the base64.)

Another tip that would help a lot is that to set the current directory to a different drive one would have to use %~d0 first, then cd %~dp0. This will change the directory to the batch file's drive, then change to its folder.

Alternatively, for #oneLinerLovers, as @Omni pointed out in the comments cd /d %~dp0 will change both the drive and directory :)

Hope this helps someone.

The question title asks how to host material icons offline but the body clarifies that the objective is to use the material icons offline (emphasis mine).

Using your own copy of the material icons files is a valid approach/implementation. Another, for those that can use a service worker is to let the service worker take care of it. That way you don't have the hassle of obtaining a copy and keeping it up to date.

For example, generate a service worker using Workbox, using the simplest approach of running workbox-cli and accepting the defaults, then append the following text to the generated service worker:

workboxSW.router.registerRoute('https://fonts.googleapis.com/(.*)',
workboxSW.strategies.cacheFirst({
  cacheName: 'googleapis',
  cacheExpiration: {
    maxEntries: 20
  },
  cacheableResponse: {statuses: [0, 200]}
})
);

You can then check it was cached in Chrome using F12 > Application > Storage > IndexedDB and look for an entry with googleapis in the name.

The other answers explained it well already, but I'd like to offer another experiment illustrating the nature of range objects:

>>> r = range(5)
>>> for i in r:
        print(i, 2 in r, list(r))

0 True [0, 1, 2, 3, 4]
1 True [0, 1, 2, 3, 4]
2 True [0, 1, 2, 3, 4]
3 True [0, 1, 2, 3, 4]
4 True [0, 1, 2, 3, 4]

As you can see, a range object is an object that remembers its range and can be used many times (even while iterating over it), not just a one-time generator.

CAUTION: commit any work you wish to retain first.

You may reset your workspace (and recover the deleted files)

git checkout ./*

If you use has_many through, and want to alias:

has_many :alias_name, through: model_name, source: initial_name

using Eloquent

$data = array(
    array('user_id'=>'Coder 1', 'subject_id'=> 4096),
    array('user_id'=>'Coder 2', 'subject_id'=> 2048),
    //...
);

Model::insert($data);

Posting this in an effort to help others with similar problems. I solved this issue with a five step approach -- save the context, translate the context, rotate the context, draw the text, then restore the context to its saved state.

I think of translations and transforms to the context as manipulating the coordinate grid overlaid on the canvas. By default the origin (0,0) starts in the upper left hand corner of the canvas. X increases from left to right, Y increases from top to bottom. If you make an "L" w/ your index finger and thumb on your left hand and hold it out in front of you with your thumb down, your thumb would point in the direction of increasing Y and your index finger would point in the direction of increasing X. I know it's elementary, but I find it helpful when thinking about translations and rotations. Here's why:

When you translate the context, you move the origin of the coordinate grid to a new location on the canvas. When you rotate the context, think of rotating the "L" you made with your left hand in a clockwise direction the amount indicated by the angle you specify in radians about the origin. When you strokeText or fillText, specify your coordinates in relation to the newly aligned axes. To orient your text so it's readable from bottom to top, you would translate to a position below where you want to start your labels, rotate by -90 degrees and fill or strokeText, offsetting each label along the rotated x axis. Something like this should work:

 context.save();
 context.translate(newx, newy);
 context.rotate(-Math.PI/2);
 context.textAlign = "center";
 context.fillText("Your Label Here", labelXposition, 0);
 context.restore();

.restore() resets the context back to the state it had when you called .save() -- handy for returning things back to "normal".

I know my answer it's too late, but it might helpful to other's
Try,

Void Main()
{
string filename = @"test.txt";
string filePath= AppDomain.CurrentDomain.BaseDirectory + filename ;
Console.WriteLine(filePath);
}

Use OleDB, you can create, read, and edit excel files pretty easily. Read the MSDN docs for more info:

http://msdn.microsoft.com/en-us/library/aa288452(VS.71).aspx

I've used OleDB to read from excel files and I know you can create them, but I haven't done it firsthand.

https://github.com/passsy/android-HoloCircularProgressBar is one example of a library that does this. As Tenfour04 stated, it will have to be somewhat custom, in that this is not supported directly out of the box. If this library doesn't behave as you wish, you can fork it and modify the details to make it work to your liking. If you implement something that others can then reuse, you could even submit a pull request to get that merged back in!

Well, you can just put multiple "where" clauses in directly, but I don't think you want to. Multiple "where" clauses ends up with a more restrictive filter - I think you want a less restrictive one. I think you really want:

DataTable tempData = (DataTable)grdUsageRecords.DataSource;
var query = from r in tempData.AsEnumerable()
            where r.Field<string>("UserName") != "XXXX" &&
                  r.Field<string>("UserName") != "YYYY"
            select r;

DataTable newDT = query.CopyToDataTable();

Note the && instead of ||. You want to select the row if the username isn't XXXX and the username isn't YYYY.

EDIT: If you have a whole collection, it's even easier. Suppose the collection is called ignoredUserNames:

DataTable tempData = (DataTable)grdUsageRecords.DataSource;
var query = from r in tempData.AsEnumerable()
            where !ignoredUserNames.Contains(r.Field<string>("UserName"))
            select r;

DataTable newDT = query.CopyToDataTable();

Ideally you'd want to make this a HashSet<string> to avoid the Contains call taking a long time, but if the collection is small enough it won't make much odds.

<hr> is not from struts. It is just an HTML tag.

So, take a look here: http://www.microbion.co.uk/web/vertline.htm This link will give you a couple of tips.

The pointer-events could be useful for this problem as you would be able to put a div over the arrow button, but still be able to click the arrow button.

The pointer-events css makes it possible to click through a div.

This approach will not work for IE versions older than IE11, however. You could something working in IE8 and IE9 if the element you put on top of the arrow button is an SVG element, but it will be more complicated to style the button the way you want proceeding like this.

Here a Js fiddle example: http://jsfiddle.net/e7qnqzx6/2/

Scott Murray wrote a great explanation of this^[1]. For instance, for the code snippet:

svg.append("g")
    .attr("class", "axis")
    .attr("transform", "translate(0," + h + ")")
    .call(xAxis);

He explains using the following:

Note that we use attr() to apply transform as an attribute of g. SVG transforms are quite powerful, and can accept several different kinds of transform definitions, including scales and rotations. But we are keeping it simple here with only a translation transform, which simply pushes the whole g group over and down by some amount.

Translation transforms are specified with the easy syntax of translate(x,y), where x and y are, obviously, the number of horizontal and vertical pixels by which to translate the element.

Checkpoints capture the exact value of all parameters (tf.Variable objects) used by a model. Checkpoints do not contain any description of the computation defined by the model and thus are typically only useful when source code that will use the saved parameter values is available.

The SavedModel format on the other hand includes a serialized description of the computation defined by the model in addition to the parameter values (checkpoint). Models in this format are independent of the source code that created the model. They are thus suitable for deployment via TensorFlow Serving, TensorFlow Lite, TensorFlow.js, or programs in other programming languages (the C, C++, Java, Go, Rust, C# etc. TensorFlow APIs).

simple_save

Many good answer, for completeness I'll add my 2 cents: simple_save. Also a standalone code example using the tf.data.Dataset API.

Python 3 ; Tensorflow 1.14

import tensorflow as tf
from tensorflow.saved_model import tag_constants

with tf.Graph().as_default():
    with tf.Session() as sess:
        ...

        # Saving
        inputs = {
            "batch_size_placeholder": batch_size_placeholder,
            "features_placeholder": features_placeholder,
            "labels_placeholder": labels_placeholder,
        }
        outputs = {"prediction": model_output}
        tf.saved_model.simple_save(
            sess, 'path/to/your/location/', inputs, outputs
        )

Restoring:

graph = tf.Graph()
with restored_graph.as_default():
    with tf.Session() as sess:
        tf.saved_model.loader.load(
            sess,
            [tag_constants.SERVING],
            'path/to/your/location/',
        )
        batch_size_placeholder = graph.get_tensor_by_name('batch_size_placeholder:0')
        features_placeholder = graph.get_tensor_by_name('features_placeholder:0')
        labels_placeholder = graph.get_tensor_by_name('labels_placeholder:0')
        prediction = restored_graph.get_tensor_by_name('dense/BiasAdd:0')

        sess.run(prediction, feed_dict={
            batch_size_placeholder: some_value,
            features_placeholder: some_other_value,
            labels_placeholder: another_value

Standalone example

Original blog post

The following code generates random data for the sake of the demonstration.

1. We start by creating the placeholders. They will hold the data at runtime. From them, we create the Dataset and then its Iterator. We get the iterator's generated tensor, called input_tensor which will serve as input to our model.
2. The model itself is built from input_tensor: a GRU-based bidirectional RNN followed by a dense classifier. Because why not.
3. The loss is a softmax_cross_entropy_with_logits, optimized with Adam. After 2 epochs (of 2 batches each), we save the "trained" model with tf.saved_model.simple_save. If you run the code as is, then the model will be saved in a folder called simple/ in your current working directory.
4. In a new graph, we then restore the saved model with tf.saved_model.loader.load. We grab the placeholders and logits with graph.get_tensor_by_name and the Iterator initializing operation with graph.get_operation_by_name.
5. Lastly we run an inference for both batches in the dataset, and check that the saved and restored model both yield the same values. They do!

You can use an inflater with TableRow:

for (int i = 0; i < months; i++) {
    
    View view = getLayoutInflater ().inflate (R.layout.list_month_data, null, false);
        
    TextView textView = view.findViewById (R.id.title);
    
    textView.setText ("Text");
        
    tableLayout.addView (view);
    
}

Based on reading your answer and seeing how you likely came up with it, I believe you think an "exception-in-progress" has "precedence". Keep in mind:

When an new exception is thrown in a catch block or finally block that will propagate out of that block, then the current exception will be aborted (and forgotten) as the new exception is propagated outward. The new exception starts unwinding up the stack just like any other exception, aborting out of the current block (the catch or finally block) and subject to any applicable catch or finally blocks along the way.

Note that applicable catch or finally blocks includes:

When a new exception is thrown in a catch block, the new exception is still subject to that catch's finally block, if any.

Now retrace the execution remembering that, whenever you hit throw, you should abort tracing the current exception and start tracing the new exception.

Here are some differences between the two:

• Atom is open source (MIT License)
• A single user license for Sublime Text costs $70.

• Atom is written in Node.js, CoffeeScript, HTML and LESS.
• Sublime Text is written in C++, Python for plugins, and Objective-C for Cocoa integration

• Atom has a built-in package manager*
• Sublime Text depends on a third-party solution for package management (Wbond Package Control)

• At the time of writing this (05/20/2014), there are Atom binaries only for Mac OS X (10.8 or later). If you want to use it under Windows or Linux, you'll have to build it. Update: Nowadays, there are Atom binaries for Mac OS X (10.8 or later) Windows and Linux.
• Sublime Text binaries are available for Mac OS X, Windows (installable or portable) and Linux (as a .deb or tarball)

• Atom settings can be configured either through a user-friendly interface or directly by editing configuration files.
• Sublime Text only allows you to change settings through configuration files.

*Though APM is a separated tool, it's bundled and installed automatically with Atom

You can also get the last command from history and subtract its EndExecutionTime from its StartExecutionTime.

.\do_something.ps1  
$command = Get-History -Count 1  
$command.EndExecutionTime - $command.StartExecutionTime

I have a slightly different situation whereby my eclipse stops responding and I have had to kill the session. After restarting Juno, then the particular project I was working on disappeared although .project file exists. Trying to import back into Eclipse would yield the same "Some projects cannot be imported .." or "A project with this name already exists" if trying to create a new project.

In the end, since I was using Working Sets, I managed to find this file .metadata.plugins\org.eclipse.ui.workbench\workingsets.xml. Manually added the missing entry and restarted eclipse and voila, it came back.

You could do this in a single traversal, if you are willing to sacrifice memory. You can simply tally whether you have seen an integer or not in a hash/associative array. If you have already seen a number, remove it as you go, or better yet, move numbers you have not seen into a new array, avoiding any shifting in the original array.

In Perl:

foreach $i (@myary) {
    if(!defined $seen{$i}) {
        $seen{$i} = 1;
        push @newary, $i;
    }
}

This is how I do it.

import numpy as np

def dt2cal(dt):
    """
    Convert array of datetime64 to a calendar array of year, month, day, hour,
    minute, seconds, microsecond with these quantites indexed on the last axis.

    Parameters
    ----------
    dt : datetime64 array (...)
        numpy.ndarray of datetimes of arbitrary shape

    Returns
    -------
    cal : uint32 array (..., 7)
        calendar array with last axis representing year, month, day, hour,
        minute, second, microsecond
    """

    # allocate output 
    out = np.empty(dt.shape + (7,), dtype="u4")
    # decompose calendar floors
    Y, M, D, h, m, s = [dt.astype(f"M8[{x}]") for x in "YMDhms"]
    out[..., 0] = Y + 1970 # Gregorian Year
    out[..., 1] = (M - Y) + 1 # month
    out[..., 2] = (D - M) + 1 # dat
    out[..., 3] = (dt - D).astype("m8[h]") # hour
    out[..., 4] = (dt - h).astype("m8[m]") # minute
    out[..., 5] = (dt - m).astype("m8[s]") # second
    out[..., 6] = (dt - s).astype("m8[us]") # microsecond
    return out

It's vectorized across arbitrary input dimensions, it's fast, its intuitive, it works on numpy v1.15.4, it doesn't use pandas.

I really wish numpy supported this functionality, it's required all the time in application development. I always get super nervous when I have to roll my own stuff like this, I always feel like I'm missing an edge case.

Try this Bash syntax instead of trying to use an external program expr:

count=$((FIRSTV-SECONDV))

BTW, the correct syntax of using expr is:

count=$(expr $FIRSTV - $SECONDV)

But keep in mind using expr is going to be slower than the internal Bash syntax I provided above.

what worked for me was using this:

$data = $request->request->all();
$name = $data['form']['name'];

You have to use == to compare (or even ===, if you want to compare types). A single = is for assignment.

if (one == 'rock' && two == 'rock') {
    console.log('Tie! Try again!');
}

Description

Assuming i understand your question.

You can get the selected row using the DataGridView.SelectedRows Collection. If your DataGridView allows only one selected, have a look at my sample.

DataGridView.SelectedRows Gets the collection of rows selected by the user.

Sample

if (dataGridView1.SelectedRows.Count != 0)
{
    DataGridViewRow row = this.dataGridView1.SelectedRows[0];
    row.Cells["ColumnName"].Value
}

More Information

• MSDN - DataGridView.SelectedRows Property

Append the sheet name to the formula which makes the reference absolute. For example, if the cell reference is =T7 make it =Sheet1!T7. Paste-link would have done the same thing except only when pasting to another sheet. Paste-link does not work as expected if you are pasting in to the same sheet.

Afterall, you could edit the .vimrc,then add the conf

set tabstop=4

Or exec the command

This is the way i ve got the value of a property value of a dinamic:

    public dynamic Post(dynamic value)
    {            
        try
        {
            if (value != null)
            {
                var valorCampos = "";

                foreach (Newtonsoft.Json.Linq.JProperty item in value)
                {
                    if (item.Name == "valorCampo")//property name
                        valorCampos = item.Value.ToString();
                }                                           

            }
        }
        catch (Exception ex)
        {

        }


    }

This works in Cygwin but it should be effective in Linux as well.

ps -W | awk '/ruby/,NF=1' | xargs kill -f

or

ps -W | awk '$0~z,NF=1' z=ruby | xargs kill -f

Bash Pitfalls

The python shutil.copytree method its a mess. I've done one that works correctly:

def copydirectorykut(src, dst):
    os.chdir(dst)
    list=os.listdir(src)
    nom= src+'.txt'
    fitx= open(nom, 'w')

    for item in list:
        fitx.write("%s\n" % item)
    fitx.close()

    f = open(nom,'r')
    for line in f.readlines():
        if "." in line:
            shutil.copy(src+'/'+line[:-1],dst+'/'+line[:-1])
        else:
            if not os.path.exists(dst+'/'+line[:-1]):
                os.makedirs(dst+'/'+line[:-1])
                copydirectorykut(src+'/'+line[:-1],dst+'/'+line[:-1])
            copydirectorykut(src+'/'+line[:-1],dst+'/'+line[:-1])
    f.close()

    os.chdir('..')

The has_many :choices creates an association named choices, not choice. Try using current_user.choices instead.

See the ActiveRecord::Associations documentation for information about about the has_many magic.

DECLARE @theDate DATETIME
SET @theDate = '2010-01-01'

Then change your query to use this logic:

AND 
(
    tblWO.OrderDate > DATEADD(MILLISECOND, -1, @theDate) 
    AND tblWO.OrderDate < DATEADD(DAY, 1, @theDate)
)

I generally find the conditional command concatenation operators much more convenient than ERRORLEVEL.

yourCommand && (
  echo yourCommand was successful
) || (
  echo yourCommand failed
)

There is one complication you should be aware of. The error branch will fire if the last command in the success branch raises an error.

yourCommand && (
  someCommandThatMayFail
) || (
  echo This will fire if yourCommand or someCommandThatMayFail raises an error
)

The fix is to insert a harmless command that is guaranteed to succeed at the end of the success branch. I like to use (call ), which does nothing except set the ERRORLEVEL to 0. There is a corollary (call) that does nothing except set the ERRORLEVEL to 1.

yourCommand && (
  someCommandThatMayFail
  (call )
) || (
  echo This can only fire if yourCommand raises an error
)

See Foolproof way to check for nonzero (error) return code in windows batch file for examples of the intricacies needed when using ERRORLEVEL to detect errors.

To be sure what symlink is needed (depend on mysql version and os version) :

$ locate libmysqlclient.18.dylib
/usr/local/mysql-5.6.24-osx10.8-x86_64/lib/libmysqlclient.18.dylib

and so :

ln -s /usr/local/mysql-5.6.24-osx10.8-x86_64/lib/libmysqlclient.18.dylib /usr/lib/libmysqlclient.18.dylib

Here is some code using java 6 to get you started:

JSONObject jo = new JSONObject();
jo.put("firstName", "John");
jo.put("lastName", "Doe");

JSONArray ja = new JSONArray();
ja.put(jo);

JSONObject mainObj = new JSONObject();
mainObj.put("employees", ja);

Edit: Since there has been a lot of confusion about put vs add here I will attempt to explain the difference. In java 6 org.json.JSONArray contains the put method and in java 7 javax.json contains the add method.

An example of this using the builder pattern in java 7 looks something like this:

JsonObject jo = Json.createObjectBuilder()
  .add("employees", Json.createArrayBuilder()
    .add(Json.createObjectBuilder()
      .add("firstName", "John")
      .add("lastName", "Doe")))
  .build();

If you really want to create them on the fly you can assign to the dict that is returned by either globals() or locals() depending on what namespace you want to create them in:

globals()['somevar'] = 'someval'
print somevar  # prints 'someval'

But I wouldn't recommend doing that. In general, avoid global variables. Using locals() often just obscures what you are really doing. Instead, create your own dict and assign to it.

mydict = {}
mydict['somevar'] = 'someval'
print mydict['somevar']

Learn the python zen; run this and grok it well:

>>> import this

 @Override
protected void onRestart() {
    super.onRestart();
    finish();
    overridePendingTransition(0, 0);
    startActivity(getIntent());
    overridePendingTransition(0, 0);
}

In previous activity use this code. This will do a smooth transition and reload the activity when you come back by pressing back button.

Can you provide an example, because put should work fine as well?

Documentation -

The type of request to make ("POST" or "GET"); the default is "GET". Note: Other HTTP request methods, such as PUT and DELETE, can also be used here, but they are not supported by all browsers.

Have the example in fiddle and the form parameters are passed fine (as it is put it will not be appended to url) -

$.ajax({
  url: '/echo/html/',
  type: 'PUT',
  data: "name=John&location=Boston",
  success: function(data) {
    alert('Load was performed.');
  }
});

For me the case was completely different. I had created a studio64.exe.vmoptions file in C:\Users\YourUserName\.AndroidStudio3.4\config. In that folder, I had a typo of extra spaces. Due to that I was getting the same error.

I replaced the studio64.exe.vmoptions with the following code.

# custom Android Studio VM options, see https://developer.android.com/studio/intro/studio-config.html

Working with atom (1.21.1 ia32)... i got the same error, even though i added a reference to my pipe in the app.module.ts and in the declarations within app.module.ts

solution was to restart my node instance... stopping the website and then doing ng serve again... going to localhost:4200 worked like a charm after this restart

You can follow this Google JavaScript Style Guide

In general, use functionNamesLikeThis, variableNamesLikeThis, ClassNamesLikeThis, EnumNamesLikeThis, methodNamesLikeThis, and SYMBOLIC_CONSTANTS_LIKE_THIS.

EDIT: See nice collection of JavaScript Style Guides And Beautifiers.

Well, we have a few ways we can work with the delegates system or using storyboardSegue:

1. As working with setter and getter methods, like in viewController.h

    @property (retain, nonatomic) NSString *str;
   

   Now, in viewController.m

   @synthesize str;
   

   Here I have a PDF URL and a segue to another viewController like this and pdfObject is my pdfModel. It is basically an NSOBJECT class.

    str = [NSString stringWithFormat:@"%@", pdfObject.objPath];
    NSLog(@"pdfUrl :***: %@ :***:", pdfUrl);
   
    [self performSegueWithIdentifier:@"programPDFViewController_segue" sender:self];
   
    #pragma mark - Navigation
   
    // In a storyboard-based application, you will often want to do a little preparation before navigation
   
    - (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
   
         if ([[segue identifier] isEqualToString:@"programPDFViewController_segue"]) {
             programPDFViewController *pdfVC = [segue destinationViewController];
             [pdfVC setRecievedPdfUrl:str];
         }
    }
   

   Now successfully I received my PDF URL string and other ViewController and use that string in webview...

2. As working with delegates like this I have one NSObject class of utilities containing my methods of dateFormatter, sharedInstance, EscapeWhiteSpaceCharacters, convertImageToGrayScale and more method I worked with throughout the application so now in file utilities.h.

   In this, you don’t need to create variables every time parsing data from one to another view controller. One time, you create a string variable in file utilities.h.

   Just make it nil and use it again.

    @interface Utilities : NSObject
   

   File Utilities.h:

    +(Utilities*)sharedInstance;
   
    @property(nonatomic, retain)NSString* strUrl;
   

   Now in file utilities.m:

    @implementation utilities
   
    +(utilities*)sharedInstance
    {
        static utilities* sharedObj = nil;
        if (sharedObj == nil) {
            sharedObj = [[utilities alloc] init];
        }
        return sharedObj;
    }
   

   Now it's done, come to your file firstViewController.m and call the delegate

   NSString*str = [NSString stringWithFormat:@"%@", pdfObject.objPath];

   [Connection sharedInstance].strUrl = nil; [Connection sharedInstance].strUrl = str;

   Now go to you file secondViewController.m directly, and use it without creating a variable

   In viewwillapear what I did:

    -(void)viewWillAppear:(BOOL)animated {
        [super viewWillAppear:YES];
   
        [self webViewMethod:[Connection sharedInstance].strUrl];
    }
   
   
    -(void)WebViewMethod:(NSString)Url {
   
        // Working with webview. Enjoy coding :D
    }
   

This delegate work is reliable with memory management.

I've used an interesting conditional formatting in a recent file of mine and thought it would be useful to others too. So this answer is meant for completeness to the previous ones.

It should demonstrate what this amazing feature is capable of, and especially how the $ thing works.

Example table

The color from D to G depend on the values in columns A, B and C. But the formula needs to check values that are fixed horizontally (user, start, end), and values that are fixed vertically (dates in row 1). That's where the dollar sign gets useful.

Solution

There are 2 users in the table, each with a defined color, respectively foo (blue) and bar (yellow).
We have to use the following conditional formatting rules, and apply both of them on the same range (D2:G3):

1. =AND($A2="foo", D$1>=$B2, D$1<=$C2)
2. =AND($A2="bar", D$1>=$B2, D$1<=$C2)

In English, the condition means:
User is name, and date of current cell is after start and before end

Notice how the only thing that changes between the 2 formulas, is the name of the user. This makes it really easy to reuse with many other users!

Explanations

Important: Variable rows and columns are relative to the start of the range. But fixed values are not affected.

It is easy to get confused with relative positions. In this example, if we had used the range D1:G3 instead of D2:G3, the color formatting would be shifted 1 row up.
To avoid that, remember that the value for variable rows and columns should correspond to the start of the containing range.

In this example, the range that contains colors is D2:G3, so the start is D2.

User, start, and end vary with rows
-> Fixed columns A B C, variable rows starting at 2: $A2, $B2, $C2

Dates vary with columns
-> Variable columns starting at D, fixed row 1: D$1

I would just set padding: -whateverYouWantpx;

@Mike M. and I found an issue with the accepted answer (see our comments):

Basically, there is no point in going through the for loop if we are not concatenating the multipart message each time:

for (int i = 0; i < msgs.length; i++) {
    msgs[i] = SmsMessage.createFromPdu((byte[])pdus[i]);
    msg_from = msgs[i].getOriginatingAddress();
    String msgBody = msgs[i].getMessageBody();
}

Notice that we just set msgBody to the string value of the respective part of the message no matter what index we are on, which makes the entire point of looping through the different parts of the SMS message useless, since it will just be set to the very last index value. Instead we should use +=, or as Mike noted, StringBuilder:

All in all, here is what my SMS receiving code looks like:

if (myBundle != null) {
    Object[] pdus = (Object[]) myBundle.get("pdus"); // pdus is key for SMS in bundle

    //Object [] pdus now contains array of bytes
    messages = new SmsMessage[pdus.length];
    for (int i = 0; i < messages.length; i++) {
         messages[i] = SmsMessage.createFromPdu((byte[]) pdus[i]); //Returns one message, in array because multipart message due to sms max char
         Message += messages[i].getMessageBody(); // Using +=, because need to add multipart from before also
    }

    contactNumber = messages[0].getOriginatingAddress(); //This could also be inside the loop, but there is no need
}

Just putting this answer out there in case anyone else has the same confusion.

Try the out-of-the-box solution (ASP.NET MVC 4 or later):

@{
    var bundle = BundleTable.Bundles.GetRegisteredBundles().First(b => b.Path == "~/js");

    bundle.Include("~/Scripts/myFile.js");
}

You can use Array.ForEach()

Array.ForEach(employees, employee => {
   Array.ForEach(employee.Departments, department => department.SomeProperty = null);
   Collection.AddRange(employee.Departments);
});

If layoutparams is already defined (in XML or dynamically), Here's a one liner:

((LinearLayout.LayoutParams) mView.getLayoutParams()).weight = 1;

Percent encoding. Replace the hash with %23.

For me the solution was to have

"location=0"

in the 3rd parameter. Tested on latest FF/Chrome and an old version of IE11

Full method call I use is below (As I like to use a variable width):

window.open(url, "window" + id, 'toolbar=0,location=0,scrollbars=1,statusbar=1,menubar=0,resizable=1,width=' + width + ',height=800,left=100,top=50');

You have it almost done. Just explicitly say where to create the file

@echo off
  echo.>"d:\testing\dblank.txt"

This creates a file containing a blank line (CR + LF = 2 bytes).

If you want the file empty (0 bytes)

@echo off
  break>"d:\testing\dblank.txt"

You can Use <ng-container> and <ng-template> for Achieve This

<ng-container *ngIf="isValid; then template1 else template2"></ng-container>

<ng-template #template1>
     <div>Template 1 contains</div>
</ng-template>

<ng-template #template2>
     <div>Template 2 contains </div>
</ng-template>

Hope This will helps ... !!!

InputStream in = new ByteArrayInputStream(yourstring.getBytes());

For concatenating selectors together when nesting, you need to use the parent selector (&):

.class {
    margin:20px;
    &:hover {
        color:yellow;
    }
}

When iterating over cell arrays of strings, the loop variable (let's call it f) becomes a single-element cell array. Having to write f{1} everywhere gets tedious, and modifying the loop variable provides a clean workaround.

% This example transposes each field of a struct.
s.a = 1:3;
s.b = zeros(2,3);
s % a: [1 2 3]; b: [2x3 double]
for f = fieldnames(s)'
    s.(f{1}) = s.(f{1})';
end
s % a: [3x1 double]; b: [3x2 double]

% Redefining f simplifies the indexing.
for f = fieldnames(s)'
    f = f{1};
    s.(f) = s.(f)';
end
s % back to a: [1 2 3]; b: [2x3 double]

Probably you try to send your data from mydomain.com to www.mydomain.com or reverse, NOTE you missed "www". http://mydomain.com and http://www.mydomain.com are different domains to javascript.

Just for clarification: setRequestProperty("User-Agent", "Mozilla ...") now works just fine and doesn't append java/xx at the end! At least with Java 1.6.30 and newer.

I listened on my machine with netcat(a port listener):

$ nc -l -p 8080

It simply listens on the port, so you see anything which gets requested, like raw http-headers.

And got the following http-headers without setRequestProperty:

GET /foobar HTTP/1.1
User-Agent: Java/1.6.0_30
Host: localhost:8080
Accept: text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2
Connection: keep-alive

And WITH setRequestProperty:

GET /foobar HTTP/1.1
User-Agent: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.4; en-US; rv:1.9.2.2) Gecko/20100316 Firefox/3.6.2
Host: localhost:8080
Accept: text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2
Connection: keep-alive

As you can see the user agent was properly set.

Full example:

import java.io.IOException;
import java.net.URL;
import java.net.URLConnection;


public class TestUrlOpener {

    public static void main(String[] args) throws IOException {
        URL url = new URL("http://localhost:8080/foobar");
        URLConnection hc = url.openConnection();
        hc.setRequestProperty("User-Agent", "Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.4; en-US; rv:1.9.2.2) Gecko/20100316 Firefox/3.6.2");

        System.out.println(hc.getContentType());
    }

}

As said in the documentation:

Must: The clause (query) must appear in matching documents.

Should: The clause (query) should appear in the matching document. In a boolean query with no must clauses, one or more should clauses must match a document. The minimum number of should clauses to match can be set using the minimum_should_match parameter.

In other words, results will have to be matched by all the queries present in the must clause ( or match at least one of the should clauses if there is no must clause.

Since you want your results to satisfy all the queries, you should use must.

You can indeed use filters inside a boolean query.

TL;DR

TEXT

• fixed max size of 65535 characters (you cannot limit the max size)
• takes 2 + c bytes of disk space, where c is the length of the stored string.
• cannot be (fully) part of an index. One would need to specify a prefix length.

VARCHAR(M)

• variable max size of M characters
• M needs to be between 1 and 65535
• takes 1 + c bytes (for M ≤ 255) or 2 + c (for 256 ≤ M ≤ 65535) bytes of disk space where c is the length of the stored string
• can be part of an index

More Details

TEXT has a fixed max size of 2¹6-1 = 65535 characters.
VARCHAR has a variable max size M up to M = 2¹6-1.
So you cannot choose the size of TEXT but you can for a VARCHAR.

The other difference is, that you cannot put an index (except for a fulltext index) on a TEXT column.
So if you want to have an index on the column, you have to use VARCHAR. But notice that the length of an index is also limited, so if your VARCHAR column is too long you have to use only the first few characters of the VARCHAR column in your index (See the documentation for CREATE INDEX).

But you also want to use VARCHAR, if you know that the maximum length of the possible input string is only M, e.g. a phone number or a name or something like this. Then you can use VARCHAR(30) instead of TINYTEXT or TEXT and if someone tries to save the text of all three "Lord of the Ring" books in your phone number column you only store the first 30 characters :)

Edit: If the text you want to store in the database is longer than 65535 characters, you have to choose MEDIUMTEXT or LONGTEXT, but be careful: MEDIUMTEXT stores strings up to 16 MB, LONGTEXT up to 4 GB. If you use LONGTEXT and get the data via PHP (at least if you use mysqli without store_result), you maybe get a memory allocation error, because PHP tries to allocate 4 GB of memory to be sure the whole string can be buffered. This maybe also happens in other languages than PHP.

However, you should always check the input (Is it too long? Does it contain strange code?) before storing it in the database.

Notice: For both types, the required disk space depends only on the length of the stored string and not on the maximum length.
E.g. if you use the charset latin1 and store the text "Test" in VARCHAR(30), VARCHAR(100) and TINYTEXT, it always requires 5 bytes (1 byte to store the length of the string and 1 byte for each character). If you store the same text in a VARCHAR(2000) or a TEXT column, it would also require the same space, but, in this case, it would be 6 bytes (2 bytes to store the string length and 1 byte for each character).

For more information have a look at the documentation.

Finally, I want to add a notice, that both, TEXT and VARCHAR are variable length data types, and so they most likely minimize the space you need to store the data. But this comes with a trade-off for performance. If you need better performance, you have to use a fixed length type like CHAR. You can read more about this here.

1. you need to create and id for the buttons you need to refference: btn1.setId(1);
2. you can use the params variable to add parameters to your layout, i think the method is addRule(), check out the android java docs for this LayoutParams object.

I also recommend using PIL's thumbnail method, because it removes all the ratio hassles from you.

One important hint, though: Replace

im.thumbnail(size)

with

im.thumbnail(size,Image.ANTIALIAS)

by default, PIL uses the Image.NEAREST filter for resizing which results in good performance, but poor quality.

If your looking to type up the message and then your bot will send it to the user, here is the code. It also has a role restriction on it :)

case 'dm':
  mentiondm = message.mentions.users.first();
  message.channel.bulkDelete(1);
  if (!message.member.roles.cache.some(role => role.name === "Owner")) return message.channel.send('Beep Boing: This command is way too powerful for you to use!');
  if (mentiondm == null) return message.reply('Beep Boing: No user to send message to!');
  mentionMessage = message.content.slice(3);
  mentiondm.send(mentionMessage);
  console.log('Message Sent!')
  break;

Leaflet Markers are stored as files unlike other objects (like Polylines, etc.)

If you want your own markers, you can find The official Leaflet Tutorial that explains how to do it.

EDIT :

After reading this conversation with the main developer I searched for the marker SVG and here it is.

With this you should be able to color the marker the way you want and randomly set their color.

EDIT AGAIN :

You can use MakiMarkers to set the color of a marker and use this extension to make some random stuffs. (It's simple and well explained)

I got a solution for downloading from angular 2 without getting corrupt, using spring mvc and angular 2

1st- my return type is :-ResponseEntity from java end. Here I am sending byte[] array has return type from the controller.

2nd- to include the filesaver in your workspace-in the index page as:

<script src="https://cdnjs.cloudflare.com/ajax/libs/FileSaver.js/2014-11-29/FileSaver.min.js"></script>

3rd- at component ts write this code:

import {ResponseContentType} from '@angular.core';

let headers = new Headers({ 'Content-Type': 'application/json', 'MyApp-Application' : 'AppName', 'Accept': 'application/pdf' });
        let options = new RequestOptions({ headers: headers, responseType: ResponseContentType.Blob });
            this.http
            .post('/project/test/export',
                    somevalue,options)
              .subscribe(data => {

                  var mediaType = 'application/vnd.ms-excel';
                  let blob: Blob = data.blob();
                    window['saveAs'](blob, 'sample.xls');

                });

This will give you xls file format. If you want other formats change the mediatype and file name with right extension.

To rotate a DIV we can add some CSS that, well, rotates the DIV using CSS transform rotate.

To toggle the rotation we can keep a flag, a simple variable with a boolean value that tells us what way to rotate.

var rotated = false;

document.getElementById('button').onclick = function() {
    var div = document.getElementById('div'),
        deg = rotated ? 0 : 66;

    div.style.webkitTransform = 'rotate('+deg+'deg)'; 
    div.style.mozTransform    = 'rotate('+deg+'deg)'; 
    div.style.msTransform     = 'rotate('+deg+'deg)'; 
    div.style.oTransform      = 'rotate('+deg+'deg)'; 
    div.style.transform       = 'rotate('+deg+'deg)'; 

    rotated = !rotated;
}

var rotated = false;_x000D_
_x000D_
document.getElementById('button').onclick = function() {_x000D_
    var div = document.getElementById('div'),_x000D_
        deg = rotated ? 0 : 66;_x000D_
_x000D_
    div.style.webkitTransform = 'rotate('+deg+'deg)'; _x000D_
    div.style.mozTransform    = 'rotate('+deg+'deg)'; _x000D_
    div.style.msTransform     = 'rotate('+deg+'deg)'; _x000D_
    div.style.oTransform      = 'rotate('+deg+'deg)'; _x000D_
    div.style.transform       = 'rotate('+deg+'deg)'; _x000D_
    _x000D_
    rotated = !rotated;_x000D_
}

#div {_x000D_
    position:relative; _x000D_
    height: 200px; _x000D_
    width: 200px; _x000D_
    margin: 30px;_x000D_
    background: red;_x000D_
}

<button id="button">rotate</button>_x000D_
<br /><br />_x000D_
<div id="div"></div>

To add some animation to the rotation all we have to do is add CSS transitions

div {
    -webkit-transition: all 0.5s ease-in-out;
    -moz-transition: all 0.5s ease-in-out;
    -o-transition: all 0.5s ease-in-out;
    transition: all 0.5s ease-in-out;
}

var rotated = false;_x000D_
_x000D_
document.getElementById('button').onclick = function() {_x000D_
    var div = document.getElementById('div'),_x000D_
        deg = rotated ? 0 : 66;_x000D_
_x000D_
    div.style.webkitTransform = 'rotate('+deg+'deg)'; _x000D_
    div.style.mozTransform    = 'rotate('+deg+'deg)'; _x000D_
    div.style.msTransform     = 'rotate('+deg+'deg)'; _x000D_
    div.style.oTransform      = 'rotate('+deg+'deg)'; _x000D_
    div.style.transform       = 'rotate('+deg+'deg)'; _x000D_
    _x000D_
    rotated = !rotated;_x000D_
}

#div {_x000D_
    position:relative; _x000D_
    height: 200px; _x000D_
    width: 200px; _x000D_
    margin: 30px;_x000D_
    background: red;_x000D_
    -webkit-transition: all 0.5s ease-in-out;_x000D_
    -moz-transition: all 0.5s ease-in-out;_x000D_
    -o-transition: all 0.5s ease-in-out;_x000D_
    transition: all 0.5s ease-in-out;_x000D_
}

<button id="button">rotate</button>_x000D_
<br /><br />_x000D_
<div id="div"></div>

Another way to do it is using classes, and setting all the styles in a stylesheet, thus keeping them out of the javascript

document.getElementById('button').onclick = function() {
    document.getElementById('div').classList.toggle('rotated');
}

document.getElementById('button').onclick = function() {_x000D_
    document.getElementById('div').classList.toggle('rotated');_x000D_
}

#div {_x000D_
    position:relative; _x000D_
    height: 200px; _x000D_
    width: 200px; _x000D_
    margin: 30px;_x000D_
    background: red;_x000D_
    -webkit-transition: all 0.5s ease-in-out;_x000D_
    -moz-transition: all 0.5s ease-in-out;_x000D_
    -o-transition: all 0.5s ease-in-out;_x000D_
    transition: all 0.5s ease-in-out;_x000D_
}_x000D_
_x000D_
#div.rotated {_x000D_
    -webkit-transform : rotate(66deg); _x000D_
    -moz-transform : rotate(66deg); _x000D_
    -ms-transform : rotate(66deg); _x000D_
    -o-transform : rotate(66deg); _x000D_
    transform : rotate(66deg); _x000D_
}

<button id="button">rotate</button>_x000D_
<br /><br />_x000D_
<div id="div"></div>

Depending on where you look, you'll get slightly different answers. I've read about the subject a lot, and here's my distillation; again, these are slightly wooly and others may disagree.

Unit Tests

Tests the smallest unit of functionality, typically a method/function (e.g. given a class with a particular state, calling x method on the class should cause y to happen). Unit tests should be focussed on one particular feature (e.g., calling the pop method when the stack is empty should throw an InvalidOperationException). Everything it touches should be done in memory; this means that the test code and the code under test shouldn't:

• Call out into (non-trivial) collaborators
• Access the network
• Hit a database
• Use the file system
• Spin up a thread
• etc.

Any kind of dependency that is slow / hard to understand / initialise / manipulate should be stubbed/mocked/whatevered using the appropriate techniques so you can focus on what the unit of code is doing, not what its dependencies do.

In short, unit tests are as simple as possible, easy to debug, reliable (due to reduced external factors), fast to execute and help to prove that the smallest building blocks of your program function as intended before they're put together. The caveat is that, although you can prove they work perfectly in isolation, the units of code may blow up when combined which brings us to ...

Integration Tests

Integration tests build on unit tests by combining the units of code and testing that the resulting combination functions correctly. This can be either the innards of one system, or combining multiple systems together to do something useful. Also, another thing that differentiates integration tests from unit tests is the environment. Integration tests can and will use threads, access the database or do whatever is required to ensure that all of the code and the different environment changes will work correctly.

If you've built some serialization code and unit tested its innards without touching the disk, how do you know that it'll work when you are loading and saving to disk? Maybe you forgot to flush and dispose filestreams. Maybe your file permissions are incorrect and you've tested the innards using in memory streams. The only way to find out for sure is to test it 'for real' using an environment that is closest to production.

The main advantage is that they will find bugs that unit tests can't such as wiring bugs (e.g. an instance of class A unexpectedly receives a null instance of B) and environment bugs (it runs fine on my single-CPU machine, but my colleague's 4 core machine can't pass the tests). The main disadvantage is that integration tests touch more code, are less reliable, failures are harder to diagnose and the tests are harder to maintain.

Also, integration tests don't necessarily prove that a complete feature works. The user may not care about the internal details of my programs, but I do!

Functional Tests

Functional tests check a particular feature for correctness by comparing the results for a given input against the specification. Functional tests don't concern themselves with intermediate results or side-effects, just the result (they don't care that after doing x, object y has state z). They are written to test part of the specification such as, "calling function Square(x) with the argument of 2 returns 4".

Acceptance Tests

Acceptance testing seems to be split into two types:

Standard acceptance testing involves performing tests on the full system (e.g. using your web page via a web browser) to see whether the application's functionality satisfies the specification. E.g. "clicking a zoom icon should enlarge the document view by 25%." There is no real continuum of results, just a pass or fail outcome.

The advantage is that the tests are described in plain English and ensures the software, as a whole, is feature complete. The disadvantage is that you've moved another level up the testing pyramid. Acceptance tests touch mountains of code, so tracking down a failure can be tricky.

Also, in agile software development, user acceptance testing involves creating tests to mirror the user stories created by/for the software's customer during development. If the tests pass, it means the software should meet the customer's requirements and the stories can be considered complete. An acceptance test suite is basically an executable specification written in a domain specific language that describes the tests in the language used by the users of the system.

Conclusion

They're all complementary. Sometimes it's advantageous to focus on one type or to eschew them entirely. The main difference for me is that some of the tests look at things from a programmer's perspective, whereas others use a customer/end user focus.

Checkout the ByteSize library. It's the System.TimeSpan for bytes!

It handles the conversion and formatting for you.

var maxFileSize = ByteSize.FromKiloBytes(10);
maxFileSize.Bytes;
maxFileSize.MegaBytes;
maxFileSize.GigaBytes;

It also does string representation and parsing.

// ToString
ByteSize.FromKiloBytes(1024).ToString(); // 1 MB
ByteSize.FromGigabytes(.5).ToString();   // 512 MB
ByteSize.FromGigabytes(1024).ToString(); // 1 TB

// Parsing
ByteSize.Parse("5b");
ByteSize.Parse("1.55B");

Make sure that you are not trying to overload the insertion or extraction operators as inline functions. I had this problem and it only went away when i removed that keyword.

This worked for me

$("div").css({"left":"2000px"}).animate({"left":"0px"}, "slow");

You can't cast an object to a Double if the object is not a Double.

Check out the API.

particularly note

valueOf(double d);

and

valueOf(String s);

Those methods give you a way of getting a Double instance from a String or double primitive. (Also not the constructors; read the documentation to see how they work) The object you are trying to convert naturally has to give you something that can be transformed into a double.

Finally, keep in mind that Double instances are immutable -- once created you can't change them.

I was needing to find out just which version of .NET framework I had on my computer, and all I did was go to the control panel and select the "Uninstall a Program" option. After that, I sorted the programs by name, and found Microsoft .NET Framework 4 Client Profile.

You can specify the latest version of ruby by looking at https://www.ruby-lang.org/en/downloads/

1. Fetch the latest version:

   curl -sSL https://get.rvm.io | bash -s stable --ruby

2. Install it:

   rvm install 2.2

3. Use it as default:

   rvm use 2.2 --default

Or run the latest command from ruby:

rvm install ruby --latest
rvm use 2.2 --default

Here is an easy way of how you can do it, without having to use anything fancy, or even JSON.

First, create a server side script to handle your requests. Something like http://www.example.com/path/handler.php

You will call it with parameters, like this: .../handler.php?param1=12345&param2=67890

Inside it, after processing the recieved data, output:

document.serverResponse('..all the data, in any format that suits you..');
// Any code could be used instead, because you dont have to encode this data
// All your output will simply be executed as normal javascript

Now, in the client side script, use the following:

document.serverResponse = function(param){ console.log(param) }

var script = document.createElement('script');
script.src='http://www.example.com/path/handler.php?param1=12345&param2=67890';
document.head.appendChild(script);

The only limit of this approach, is the max length of parameters that you can send to the server. But, you can always send multiple requests.

SHIFTV puts you in select lines mode. Then "*y yanks the currently selected lines to the * register which is the clipboard. There are quite a few different registers, for different purposes. See the section on selection and drop registers for details on the differences between * and + registers on Windows and Linux.

Not sure if this is still an issue, but for me in 5.2.35CE it's possible to get the create scripts by:

1. Database --> Reverse Engineer

2. Under stored connection, choose your database

3. Hit "Next" a few times, choose which schema you want to reverse engineer, and let the tool work

4. You'll get an "EER Diagram" view with all the DB's schema. If you right click on the table you care about and choose "Copy SQL to Clipboard" I think you'll have what you need.

Hopefully this helps someone else that needs it.

If you're looking to print specific data that you already have access to, whether it's from a Store, AJAX, or available elsewhere, you can leverage my library react-print.

https://github.com/captray/react-print

It makes creating print templates much easier (assuming you already have a dependency on react). You just need to tag your HTML appropriately.

This ID should be added higher up in your actual DOM tree to exclude everything except the "print mount" below.

<div id="react-no-print"> 

This is where your react-print component will mount and wrap your template that you create:

<div id="print-mount"></div>

An example looks something like this:

var PrintTemplate = require('react-print');
var ReactDOM = require('react-dom');
var React = require('react');

var MyTemplate = React.createClass({
    render() {
        return (
            <PrintTemplate>
                <p>Your custom</p>
                <span>print stuff goes</span>
                <h1>Here</h1>
            </PrintTemplate>
        );
    }
});

ReactDOM.render(<MyTemplate/>, document.getElementById('print-mount'));

It's worth noting that you can create new or utilize existing child components inside of your template, and everything should render fine for printing.

While you could use a continue, why not just inverse the logic in your if?

while(rs.next())
{
    if(!f.exists() || f.isDirectory()){
    //proceed
    }
}

You don't even need an else {continue;} as it will continue anyway if the if conditions are not satisfied.

This works well for specific articles where the text is all wrapped in <p> tags. Since the web is an ugly place, it's not always the case.

Often, websites will have text scattered all over, wrapped in different types of tags (e.g. maybe in a <span> or a <div>, or an <li>).

To find all text nodes in the DOM, you can use soup.find_all(text=True).

This is going to return some undesired text, like the contents of <script> and <style> tags. You'll need to filter out the text contents of elements you don't want.

blacklist = [
  'style',
  'script',
  # other elements,
]

text_elements = [t for t in soup.find_all(text=True) if t.parent.name not in blacklist]

If you are working with a known set of tags, you can tag the opposite approach:

whitelist = [
  'p'
]

text_elements = [t for t in soup.find_all(text=True) if t.parent.name in whitelist]

We can't use "PHP in between JavaScript", because PHP runs on the server and JavaScript - on the client.

However we can generate JavaScript code as well as HTML, using all PHP features, including the escaping from HTML one.
