It's worth noting that Java can overload a method such as abs so that it works with an integer or a double. In C, overloading doesn't exist, so you need different functions for integer versus double.

An elegant way in Swift 3 and better to understand:

override func imageRect(forContentRect contentRect: CGRect) -> CGRect {
    let leftMargin:CGFloat = 40
    let imgWidth:CGFloat = 24
    let imgHeight:CGFloat = 24
    return CGRect(x: leftMargin, y: (contentRect.size.height-imgHeight) * 0.5, width: imgWidth, height: imgHeight)
}

override func titleRect(forContentRect contentRect: CGRect) -> CGRect {
    let leftMargin:CGFloat = 80
    let rightMargin:CGFloat = 80
    return CGRect(x: leftMargin, y: 0, width: contentRect.size.width-leftMargin-rightMargin, height: contentRect.size.height)
}
override func backgroundRect(forBounds bounds: CGRect) -> CGRect {
    let leftMargin:CGFloat = 10
    let rightMargin:CGFloat = 10
    let topMargin:CGFloat = 10
    let bottomMargin:CGFloat = 10
    return CGRect(x: leftMargin, y: topMargin, width: bounds.size.width-leftMargin-rightMargin, height: bounds.size.height-topMargin-bottomMargin)
}
override func contentRect(forBounds bounds: CGRect) -> CGRect {
    let leftMargin:CGFloat = 5
    let rightMargin:CGFloat = 5
    let topMargin:CGFloat = 5
    let bottomMargin:CGFloat = 5
    return CGRect(x: leftMargin, y: topMargin, width: bounds.size.width-leftMargin-rightMargin, height: bounds.size.height-topMargin-bottomMargin)
}

Just had the same problem. Client-side wasn't appropriate because the button was posting back information from a listview.

Saw same solution as Amaranth's on way2coding but this didn't work for me.

However, in the comments, someone posted a similar solution that does work

OnClientClick="document.getElementById('form1').target ='_blank';"

where form1 is the id of your asp.net form.

You can easily do this with the normal "Time" data type - just change the format!

Excels time/date format is simply 1.0 equals 1 full day (starting on 1/1/1900). So 36 hours would be 1.5. If you change the format to [h]:mm, you'll see 36:00.

Therefore, if you want to work with durations, you can simply use subtraction, e.g.

A1: Start:           36:00 (=1.5)
A2: End:             60:00 (=2.5) 
A3: Duration: =A2-A1 24:00 (=1.0)

You asked WHY, not how to cheat it:

Usually because of laziness of programmers of the initial implementation, because they HAVE already put way more effort in other features, delivering more odd side-effects like floats, because they were more requested by designers back then and yet they haven't taken the time to allow this so we can use the FOUR properties to push/pull an element against its neighbors (now we only have four to push, and only 2 to pull).

When html was designed, magazines loved text reflown around images back then, now hated because today we have touch trends, and love squary things with lots of space and nothing to read. That's why they put more pressure on floats than on centering, or they could have designed something like margin-top: fill; or margin: average 0; to simply align the content to the bottom, or distribute its extra space around.

In this case I think it hasn't been implemented because of the same reason that makes CSS to lack of a :parent pseudo-selector: To prevent looping evaluations.

Without being an engineer, I can see that CSS right now is made to paint elements once, remember some properties for future elements to be painted, but NEVER going back to already-painted elements.

That's why (I guess) padding is calculated on the width, because that's the value that was available at the time of starting to paint it.

If you had a negative value for padding, it would affect the outer limits, which has ALREADY been defined when the margin has already been set. I know, nothing has been painted yet, but when you read how the painting process goes, created by geniuses with 90's technology, I feel like I am asking dumb questions and just say "thanks" hehe.

One of the requirements of web pages is that they are quickly available, unlike an app that can take its time and eat the computer resources to get everything correct before displaying it, web pages need to use little resources (so they are fit in every device possible) and be scrolled in a breeze.

If you see applications with complex reflowing and positioning, like InDesign, you can't scroll that fast! It takes a big effort both from processors and graphic card to jump to next pages!

So painting and calculating forward and forgetting about an element once drawn, for now it seems to be a MUST.

I use this code to format floats. It is based on toPrecision() but it strips unnecessary zeros. I would welcome suggestions for how to simplify the regex.

function round(x, n) {
    var exp = Math.pow(10, n);
    return Math.floor(x*exp + 0.5)/exp;
}

Usage example:

function test(x, n, d) {
    var rounded = rnd(x, d);
    var result = rounded.toPrecision(n);
    result = result.replace(/\.?0*$/, '');
    result = result.replace(/\.?0*e/, 'e');
    result = result.replace('e+', 'e');
    return result;  
}

document.write(test(1.2000e45, 3, 2) + '=' + '1.2e45' + '<br>');
document.write(test(1.2000e+45, 3, 2) + '=' + '1.2e45' + '<br>');
document.write(test(1.2340e45, 3, 2) + '=' + '1.23e45' + '<br>');
document.write(test(1.2350e45, 3, 2) + '=' + '1.24e45' + '<br>');
document.write(test(1.0000, 3, 2) + '=' + '1' + '<br>');
document.write(test(1.0100, 3, 2) + '=' + '1.01' + '<br>');
document.write(test(1.2340, 4, 2) + '=' + '1.23' + '<br>');
document.write(test(1.2350, 4, 2) + '=' + '1.24' + '<br>');

One thing not clearly covered is that microsoft sql is creating in the background an unique index for the added constraint

create table Customer ( id int primary key identity (1,1) , name nvarchar(128) ) 

--Commands completed successfully.

sp_help Customer

---> index
--index_name    index_description   index_keys
--PK__Customer__3213E83FCC4A1DFA    clustered, unique, primary key located on PRIMARY   id

---> constraint
--constraint_type   constraint_name delete_action   update_action   status_enabled  status_for_replication  constraint_keys
--PRIMARY KEY (clustered)   PK__Customer__3213E83FCC4A1DFA  (n/a)   (n/a)   (n/a)   (n/a)   id


---- now adding the unique constraint

ALTER TABLE Customer ADD CONSTRAINT U_Name UNIQUE(Name)

-- Commands completed successfully.

sp_help Customer

---> index
---index_name   index_description   index_keys
---PK__Customer__3213E83FCC4A1DFA   clustered, unique, primary key located on PRIMARY   id
---U_Name   nonclustered, unique, unique key located on PRIMARY name

---> constraint
---constraint_type  constraint_name delete_action   update_action   status_enabled  status_for_replication  constraint_keys
---PRIMARY KEY (clustered)  PK__Customer__3213E83FCC4A1DFA  (n/a)   (n/a)   (n/a)   (n/a)   id
---UNIQUE (non-clustered)   U_Name  (n/a)   (n/a)   (n/a)   (n/a)   name

as you can see , there is a new constraint and a new index U_Name

Unless there is an overwhelming need to create a mess of variable names, I would just use a dictionary, where you can dynamically create the key names and associate a value to each.

a = {}
k = 0
while k < 10:
    <dynamically create key> 
    key = ...
    <calculate value> 
    value = ...
    a[key] = value 
    k += 1

There are also some interesting data structures in the new 'collections' module that might be applicable:

http://docs.python.org/dev/library/collections.html

0..param_count means "up to and including param_count". 0...param_count means "up to, but not including param_count".

Range#map does not return an Enumerable, it actually maps it to an array. It's the same as Range#to_a.

I use this method:

{% if quote.myfile %}
    <div class="">
        <a role="button" 
            href="{{ quote.myfile.url }}"
            download="{{ quote.myfile.url }}"
            class="btn btn-light text-dark ml-0">
            Download attachment
        </a>
    </div>
{% endif %}

Your main problem is thinking that the variable you declared outside of the template is the same variable being "set" inside the choose statement. This is not how XSLT works, the variable cannot be reassigned. This is something more like what you want:

<xsl:template match="class">
  <xsl:copy><xsl:apply-templates select="@*|node()"/></xsl:copy>
  <xsl:variable name="subexists">
    <xsl:choose>
      <xsl:when test="joined-subclass">true</xsl:when>
      <xsl:otherwise>false</xsl:otherwise>
    </xsl:choose>
  </xsl:variable>
  subexists:      <xsl:value-of select="$subexists" />
</xsl:template>

And if you need the variable to have "global" scope then declare it outside of the template:

<xsl:variable name="subexists">
  <xsl:choose>
     <xsl:when test="/path/to/node/joined-subclass">true</xsl:when>
     <xsl:otherwise>false</xsl:otherwise>
  </xsl:choose>
</xsl:variable>

<xsl:template match="class">
   subexists:      <xsl:value-of select="$subexists" />
</xsl:template>

As an alternative to the other answers, django-devserver outputs SQL to the console.

You should use UNION if you want to combine different resultsets. Try the following:

(SELECT * 
 FROM ( SELECT * 
        FROM orders_products 
        INNER JOIN orders ON orders_products.orders_id = orders.orders_id  
        WHERE products_id = 181) AS A)
UNION 

(SELECT * 
 FROM ( SELECT * 
        FROM orders_products 
        INNER JOIN orders ON orders_products.orders_id = orders.orders_id 
        WHERE products_id = 180) AS B
ON A.orders_id=B.orders_id)

The feedback you get on the interactive interpreter uses repr too. When you type in an expression (let it be expr), the interpreter basically does result = expr; if result is not None: print repr(result). So the second line in your example is formatting the string foo into the representation you want ('foo'). And then the interpreter creates the representation of that, leaving you with double quotes.

Why when I combine %r with double-quote and single quote escapes and print them out, it prints it the way I'd write it in my .py file but not the way I'd like to see it?

I'm not sure what you're asking here. The text single ' and double " quotes, when run through repr, includes escapes for one kind of quote. Of course it does, otherwise it wouldn't be a valid string literal by Python rules. That's precisely what you asked for by calling repr.

Also note that the eval(repr(x)) == x analogy isn't meant literal. It's an approximation and holds true for most (all?) built-in types, but the main thing is that you get a fairly good idea of the type and logical "value" from looking the the repr output.

You could try this registry hack:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters]
"DeadGWDetectDefault"=dword:00000001
"KeepAliveTime"=dword:00120000

If it works, just keep increasing the KeepAliveTime. It is currently set for 2 minutes.

If the sources are spread in many folders, and it makes sense to have individual Makefiles then as suggested before, recursive make is a good approach, but for smaller projects I find it easier to list all the source files in the Makefile with their relative path to the Makefile like this:

# common sources
COMMON_SRC := ./main.cpp \
              ../src1/somefile.cpp \
              ../src1/somefile2.cpp \
              ../src2/somefile3.cpp \

I can then set VPATH this way:

VPATH := ../src1:../src2

Then I build the objects:

COMMON_OBJS := $(patsubst %.cpp, $(ObjDir)/%$(ARCH)$(DEBUG).o, $(notdir $(COMMON_SRC)))

Now the rule is simple:

# the "common" object files
$(ObjDir)/%$(ARCH)$(DEBUG).o : %.cpp Makefile
    @echo creating $@ ...
    $(CXX) $(CFLAGS) $(EXTRA_CFLAGS) -c -o $@ $<

And building the output is even easier:

# This will make the cbsdk shared library
$(BinDir)/$(OUTPUTBIN): $(COMMON_OBJS)
    @echo building output ...
    $(CXX) -o $(BinDir)/$(OUTPUTBIN) $(COMMON_OBJS) $(LFLAGS)

One can even make the VPATH generation automated by:

VPATH := $(dir $(COMMON_SRC))

Or using the fact that sort removes duplicates (although it should not matter):

VPATH := $(sort  $(dir $(COMMON_SRC)))

    }

Here are some common options ordered from simple (one-liner) to complex (huge library). If you are interested in performance, see the micro benchmarks below.

Option 1: Code snippet - Simple (only using JDK/Android)

Option 1a: BigInteger

One very simple solution is to use the BigInteger's hex representation:

new BigInteger(1, someByteArray).toString(16);

Note that since this handles numbers not arbitrary byte-strings it will omit leading zeros - this may or may not be what you want (e.g. 000AE3 vs 0AE3 for a 3 byte input). This is also very slow, about 100x slower compared to option 2.

Option 1b: String.format()

Using the %X placeholder, String.format() is able to encode most primitive types (short, int, long) to hex:

String.format("%X", ByteBuffer.wrap(eightByteArray).getLong());

Option 1c: Integer/Long (only 4/8 Byte Arrays)

If you exclusively have 4 bytes arrays you can use the toHexString method of the Integer class:

Integer.toHexString(ByteBuffer.wrap(fourByteArray).getInt());

The same works with 8 byte arrays and Long

Long.toHexString(ByteBuffer.wrap(eightByteArray).getLong());

Option 2: Code snippet - Advanced

Here is a full featured, copy & pasteable code snippet supporting upper/lowercase and endianness. It is optimized to minimize memory complexity and maximize performance and should be compatible with all modern Java versions (5+).

private static final char[] LOOKUP_TABLE_LOWER = new char[]{0x30, 0x31, 0x32, 0x33, 0x34, 0x35, 0x36, 0x37, 0x38, 0x39, 0x61, 0x62, 0x63, 0x64, 0x65, 0x66};
private static final char[] LOOKUP_TABLE_UPPER = new char[]{0x30, 0x31, 0x32, 0x33, 0x34, 0x35, 0x36, 0x37, 0x38, 0x39, 0x41, 0x42, 0x43, 0x44, 0x45, 0x46};
        
public static String encode(byte[] byteArray, boolean upperCase, ByteOrder byteOrder) {

    // our output size will be exactly 2x byte-array length
    final char[] buffer = new char[byteArray.length * 2];

    // choose lower or uppercase lookup table
    final char[] lookup = upperCase ? LOOKUP_TABLE_UPPER : LOOKUP_TABLE_LOWER;

    int index;
    for (int i = 0; i < byteArray.length; i++) {
        // for little endian we count from last to first
        index = (byteOrder == ByteOrder.BIG_ENDIAN) ? i : byteArray.length - i - 1;
        
        // extract the upper 4 bit and look up char (0-A)
        buffer[i << 1] = lookup[(byteArray[index] >> 4) & 0xF];
        // extract the lower 4 bit and look up char (0-A)
        buffer[(i << 1) + 1] = lookup[(byteArray[index] & 0xF)];
    }
    return new String(buffer);
}

public static String encode(byte[] byteArray) {
    return encode(byteArray, false, ByteOrder.BIG_ENDIAN);
}

The full source code with Apache v2 license and decoder can be found here.

Option 3: Using a small optimized library: bytes-java

While working on my previous project, I created this little toolkit for working with bytes in Java. It has no external dependencies and is compatible with Java 7+. It includes, among others, a very fast and well tested HEX en/decoder:

import at.favre.lib.bytes.Bytes;
...
Bytes.wrap(someByteArray).encodeHex()

You can check it out on Github: bytes-java.

Option 4: Apache Commons Codec

Of course there is the good 'ol commons codecs. (warning opinion ahead) While working on the project outlined above I analyzed the code and was quite disappointed; a lot of duplicate unorganized code, obsolete and exotic codecs probably only useful for very few and quite over engineered and slow implementations of popular codecs (specifically Base64). I therefore would make an informed decision if you want to use it or an alternative. Anyways, if you still want to use it, here is a code snippet:

import org.apache.commons.codec.binary.Hex;
...
Hex.encodeHexString(someByteArray));

Option 5: Google Guava

More often than not you already have Guava as a dependency. If so just use:

import com.google.common.io.BaseEncoding;
...
BaseEncoding.base16().lowerCase().encode(someByteArray);

Option 6: Spring Security

If you use the Spring framework with Spring Security you can use the following:

import org.springframework.security.crypto.codec.Hex
...
new String(Hex.encode(someByteArray));

Option 7: Bouncy Castle

If you already use the security framework Bouncy Castle you can use its Hex util:

import org.bouncycastle.util.encoders.Hex;
...
Hex.toHexString(someByteArray);

Not Really Option 8: Java 9+ Compatibility or 'Do Not Use JAXBs javax/xml/bind/DatatypeConverter'

In previous Java (8 and below) versions the Java code for JAXB was included as runtime dependency. Since Java 9 and Jigsaw modularisation your code cannot access other code outside of it's module without explicit declaration. So be aware if you get an exception like:

java.lang.NoClassDefFoundError: javax/xml/bind/JAXBException

when running on a JVM with Java 9+. If so then switch implementations to any of the alternatives above. See also this question.

Micro Benchmarks

Here are results from a simple JMH micro benchmark encoding byte arrays of different sizes. The values are operations per second, so higher is better. Note that micro benchmarks very often do not represent real world behavior, so take these results with a grain of salt.

It's easy to do multiline replace in Notepad++. You have to use \n to represent the newline in your string, and it works for both search and replace strings. You have to make sure to select "Extended" search mode in the bottom left corner of the search window.

I found a good article describing the features here: http://markantoniou.blogspot.com/2008/06/notepad-how-to-use-regular-expressions.html

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

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

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

According to Dangerously Set innerHTML,

Improper use of the innerHTML can open you up to a cross-site scripting (XSS) attack. Sanitizing user input for display is notoriously error-prone, and failure to properly sanitize is one of the leading causes of web vulnerabilities on the internet.

Our design philosophy is that it should be "easy" to make things safe, and developers should explicitly state their intent when performing “unsafe” operations. The prop name dangerouslySetInnerHTML is intentionally chosen to be frightening, and the prop value (an object instead of a string) can be used to indicate sanitized data.

After fully understanding the security ramifications and properly sanitizing the data, create a new object containing only the key __html and your sanitized data as the value. Here is an example using the JSX syntax:

function createMarkup() {
    return {
       __html: 'First · Second'    };
 }; 

<div dangerouslySetInnerHTML={createMarkup()} /> 

Read more about it using below link:

documentation: React DOM Elements - dangerouslySetInnerHTML.

OK, here's my best pseudo math:

The equation for your line is:

Y = a + bX

Where:

b = (sum(x*y) - sum(x)sum(y)/n) / (sum(x^2) - sum(x)^2/n)

a = sum(y)/n - b(sum(x)/n)

Where sum(xy) is the sum of all x*y etc. Not particularly clear I concede, but it's the best I can do without a sigma symbol :)

... and now with added Sigma

b = (Σ(xy) - (ΣxΣy)/n) / (Σ(x^2) - (Σx)^2/n)

a = (Σy)/n - b((Σx)/n)

Where Σ(xy) is the sum of all x*y etc. and n is the number of points

Note that if the user may be in multiple zones used in the query, you may probably want to add .distinct(). Otherwise you get one user multiple times:

users_in_zones = User.objects.filter(zones__in=[zone1, zone2, zone3]).distinct()

If you actually want Yes and No buttons (and assuming WinForms):

void button_Click(object sender, EventArgs e)
{
    var message = "Yes or No?";
    var title = "Hey!";
    var result = MessageBox.Show(
        message,                  // the message to show
        title,                    // the title for the dialog box
        MessageBoxButtons.YesNo,  // show two buttons: Yes and No
        MessageBoxIcon.Question); // show a question mark icon

    // the following can be handled as if/else statements as well
    switch (result)
    {
    case DialogResult.Yes:   // Yes button pressed
        MessageBox.Show("You pressed Yes!");
        break;
    case DialogResult.No:    // No button pressed
        MessageBox.Show("You pressed No!");
        break;
    default:                 // Neither Yes nor No pressed (just in case)
        MessageBox.Show("What did you press?");
        break;
    }
}

If you want, you can deactivate this feature in your git core config using

git config core.autocrlf false

But it would be better to just get rid of the warnings using

git config core.autocrlf true

Kotlin Extension Solution

Add these somewhere, then call if (myFile.sizeInMb > 27.0) or whichever you need:

val File.size get() = if (!exists()) 0.0 else length().toDouble()
val File.sizeInKb get() = size / 1024
val File.sizeInMb get() = sizeInKb / 1024
val File.sizeInGb get() = sizeInMb / 1024
val File.sizeInTb get() = sizeInGb / 1024

If you'd like to make working with a String or Uri easier, try adding these:

fun Uri.asFile(): File = File(toString())

fun String?.asUri(): Uri? {
    try {
        return Uri.parse(this)
    } catch (e: Exception) {
    }
    return null
}

If you'd like to easily display the values as a string, these are simple wrappers. Feel free to customize the default decimals displayed

fun File.sizeStr(): String = size.toString()
fun File.sizeStrInKb(decimals: Int = 0): String = "%.${decimals}f".format(sizeInKb)
fun File.sizeStrInMb(decimals: Int = 0): String = "%.${decimals}f".format(sizeInMb)
fun File.sizeStrInGb(decimals: Int = 0): String = "%.${decimals}f".format(sizeInGb)

fun File.sizeStrWithBytes(): String = sizeStr() + "b"
fun File.sizeStrWithKb(decimals: Int = 0): String = sizeStrInKb(decimals) + "Kb"
fun File.sizeStrWithMb(decimals: Int = 0): String = sizeStrInMb(decimals) + "Mb"
fun File.sizeStrWithGb(decimals: Int = 0): String = sizeStrInGb(decimals) + "Gb"

Well you can simply use Math.pow(a,b) as you have used earlier and just convert its value by using (int) before it. Below could be used as an example to it.

int x = (int) Math.pow(a,b);

where a and b could be double or int values as you want. This will simply convert its output to an integer value as you required.

In my experience, using System.gc() is effectively a platform-specific form of optimization (where "platform" is the combination of hardware architecture, OS, JVM version and possible more runtime parameters such as RAM available), because its behaviour, while roughly predictable on a specific platform, can (and will) vary considerably between platforms.

Yes, there are situations where System.gc() will improve (perceived) performance. On example is if delays are tolerable in some parts of your app, but not in others (the game example cited above, where you want GC to happen at the start of a level, not during the level).

However, whether it will help or hurt (or do nothing) is highly dependent on the platform (as defined above).

So I think it is valid as a last-resort platform-specific optimization (i.e. if other performance optimizations are not enough). But you should never call it just because you believe it might help(without specific benchmarks), because chances are it will not.

In my Impression, the GDI approach and the DX approach are different in its nature. painting using GDI applies the FLUSH method, the FLUSH approach draws the frame then clear it and redraw another frame in the same buffer, this will result in flickering in games require high frame rate.

1. WHY DX quicker? in DX (or graphics world), a more mature method called double buffer rendering is applied, where two buffers are present, when present the front buffer to the hardware, you can render to the other buffer as well, then after the frame 1 is finished rendering, the system swap to the other buffer( locking it for presenting to hardware , and release the previous buffer ), in this way the rendering inefficiency is greatly improved.
2. WHY turning down hardware acceleration quicker? although with double buffer rendering, the FPS is improved, but the time for rendering is still limited. modern graphic hardware usually involves a lot of optimization during rendering typically like anti-aliasing, this is very computation intensive, if you don't require that high quality graphics, of course you can just disable this option. and this will save you some time.

I think what you really need is a replay system, which I totally agree with what people discussed.

If you're already in conflicted state, and you want to just accept all of theirs:

git checkout --theirs .
git add .

If you want to do the opposite:

git checkout --ours .
git add .

This is pretty drastic, so make sure you really want to wipe everything out like this before doing it.

Since required quite often it might as well be brief:

=1*(A1="")

This will not return 1 if the cell appears empty but contains say a space or a formula of the kind =IF(B1=3,"Yes","") where B1 does not contain 3.

=A1="" will return either TRUE or FALSE but those in an equation are treated as 1 and 0 respectively so multiplying TRUE by 1 returns 1.

Much the same can be achieved with the double unary --:

=--(A1="")  

where when A1 is empty one minus negates TRUE into -1 and the other negates that to 1 (just + in place of -- however does not change TRUE to 1).

I think it has to do with your second element in storbinary. You are trying to open file, but it is already a pointer to the file you opened in line file = open(local_path,'rb'). So, try to use ftp.storbinary("STOR " + i, file).

Here is a possible solution the solution #3 on my comments to blubill's answer:

    {
        echo 'Directory "', $dir, '" not found!';
    } 
    else 
    {
        $dir_contents = scandir($dir);

        foreach ($dir_contents as $file) 
        {
            $file_type = strtolower(end(explode('.', $file)));
            if ($file !== '.' && $file !== '..' && in_array($file_type, $file_display) == true)     
            {
                $name = basename($file);
                echo "<img src='img.php?name={$name}' />";

In theory SMTP can be handled by either TCP, UDP, or some 3rd party protocol.

As defined in RFC 821, RFC 2821, and RFC 5321:

SMTP is independent of the particular transmission subsystem and requires only a reliable ordered data stream channel.

In addition, the Internet Assigned Numbers Authority has allocated port 25 for both TCP and UDP for use by SMTP.

In practice however, most if not all organizations and applications only choose to implement the TCP protocol. For example, in Microsoft's port listing port 25 is only listed for TCP and not UDP.

The big difference between TCP and UDP that makes TCP ideal here is that TCP checks to make sure that every packet is received and re-sends them if they are not whereas UDP will simply send packets and not check for receipt. This makes UDP ideal for things like streaming video where every single packet isn't as important as keeping a continuous flow of packets from the server to the client.

Considering SMTP, it makes more sense to use TCP over UDP. SMTP is a mail transport protocol, and in mail every single packet is important. If you lose several packets in the middle of the message the recipient might not even receive the message and if they do they might be missing key information. This makes TCP more appropriate because it ensures that every packet is delivered.

I prefer this, because this is simple, but maybe somehow inefficient and buggy. You must check the exit code of shell command if you want a strongly error-proof program.

If you have ArrayList then convert into Array[Object]

ArrayList<String> list = new ArrayList<String>();
PreparedStatement pstmt = 
            conn.prepareStatement("select * from employee where id in (?)");
Array array = conn.createArrayOf("VARCHAR", list.toArray());
pstmt.setArray(1, array);
ResultSet rs = pstmt.executeQuery();

In many cases some antivirus also start HyperV with window start and does not allow HAXM to install. I faced this issue because of AVAST antivirus. So I uninstalled AVAST, then HAXM installed properly after restart. Then I re-installed AVAST.

So its just a check while installing as now even with AVAST installed back, HAXM works properly with virtual box and android emulators.

To me, it is better to put the transition codes with the original/minimum selectors than with the :hover or any other additional selectors:

#content #nav a {_x000D_
    background-color: #FF0;_x000D_
    _x000D_
    -webkit-transition: background-color 1000ms linear;_x000D_
    -moz-transition: background-color 1000ms linear;_x000D_
    -o-transition: background-color 1000ms linear;_x000D_
    -ms-transition: background-color 1000ms linear;_x000D_
    transition: background-color 1000ms linear;_x000D_
}_x000D_
_x000D_
#content #nav a:hover {_x000D_
    background-color: #AD310B;_x000D_
}

<div id="content">_x000D_
    <div id="nav">_x000D_
        <a href="#link1">Link 1</a>_x000D_
    </div>_x000D_

I changed the output path of the service. it should be inside bin folder of the service project. Once I put the output path back to bin, it worked.

Create a class Logger(code below), replace Console.WriteLine with Logger.Out. At the end write to a file the string Log

public static class Logger
{        
     public static StringBuilder LogString = new StringBuilder(); 
     public static void Out(string str)
     {
         Console.WriteLine(str);
         LogString.Append(str).Append(Environment.NewLine);
     }
 }

The \s metacharacter matches whitespace characters.

2. Select window->Organizer
3. Click this refresh button and that filthy yellow bar will remove instantly.

Trust me, you only have to do this. There is no need to repeat the process again and again to make sure that you doing it the right way. Just press Refresh, enter your login credentials and it's done.

You can use Environment Replacement in your Dockerfile as follows:

ENV PATH="/opt/gtk/bin:${PATH}"

Try c.ToString("F6");

(For a full explanation of numeric formatting, see MSDN)

I just use a bit of jQuery/javascript:

html:

<h1>Don't Print</h1>

<a data-target="#myModal" role="button" class="btn" data-toggle="modal">Launch modal</a>

<div class="modal fade hide" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel"      aria-hidden="true">
  <div class="modal-header">
    <button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
     <h3 id="myModalLabel">Modal to print</h3>
  </div>
  <div class="modal-body">
    <p>Print Me</p>
  </div>
  <div class="modal-footer">
    <button class="btn" data-dismiss="modal" aria-hidden="true">Close</button>
    <button class="btn btn-primary" id="printButton">Print</button>
  </div>
</div>

js:

$('#printButton').on('click', function () {
    if ($('.modal').is(':visible')) {
        var modalId = $(event.target).closest('.modal').attr('id');
        $('body').css('visibility', 'hidden');
        $("#" + modalId).css('visibility', 'visible');
        $('#' + modalId).removeClass('modal');
        window.print();
        $('body').css('visibility', 'visible');
        $('#' + modalId).addClass('modal');
    } else {
        window.print();
    }
});

here is the fiddle

I had the same error and I was missing the User variable: JAVA_HOME and the value for the SDK - "C:\Program Files\Java\jdk-9.0.1" in my case

I had the same problem, but I recognised that height constrained has been set correctly. So I did the following:

-(CGSize)MaxHeighForTextInRow:(NSString *)RowText width:(float)UITextviewWidth {

    CGSize constrainedSize = CGSizeMake(UITextviewWidth, CGFLOAT_MAX);

    NSDictionary *attributesDictionary = [NSDictionary dictionaryWithObjectsAndKeys:
                                          [UIFont fontWithName:@"HelveticaNeue" size:11.0], NSFontAttributeName,
                                          nil];

    NSMutableAttributedString *string = [[NSMutableAttributedString alloc] initWithString:RowText attributes:attributesDictionary];

    CGRect requiredHeight = [string boundingRectWithSize:constrainedSize options:NSStringDrawingUsesLineFragmentOrigin context:nil];

    if (requiredHeight.size.width > UITextviewWidth) {
        requiredHeight = CGRectMake(0, 0, UITextviewWidth, requiredHeight.size.height);
    }

    return requiredHeight.size;
}

just change the extension to .bmp.

Do this:

ByteArrayOutputStream bytes = new ByteArrayOutputStream();
_bitmapScaled.compress(Bitmap.CompressFormat.PNG, 40, bytes);

//you can create a new file name "test.BMP" in sdcard folder.
File f = new File(Environment.getExternalStorageDirectory()
                        + File.separator + "test.bmp")

It'll sound that I'm just fooling around, but try it once and it'll get saved in BMP format. Cheers!

You could use a watch instead, because that has the old and new value, but then you're adding to the digest cycle.

I'd just keep a second variable in the controller and set that.

They do different things. exec replaces the current process with the new process and never returns. system invokes another process and returns its exit value to the current process. Using backticks invokes another process and returns the output of that process to the current process.

I had the same problem and from the answers above and from what I understood what worked for me ultimately was:

1. Have a shebang line that invokes the intended script, for example,

   #!/bin/bash uses bash to execute the script

I have scripts with both kinds of shebang's. Because of this, using sh or . was not reliable, as it lead to a mis-execution (like when the script bails out having run incompletely)

The answer therefore, was

2. • Make sure the script has a shebang, so that there is no doubt about its intended handler.
   • chmod the .sh file so that it can be executed. (chmod +x file.sh)

   • Invoke it directly without any sh or .

     (./myscript.sh)

Hope this helps someone with similar question or problem.

Put it inside a table and then do on her:

var tabPom = document.getElementById("tabPomId");
$(tabPom ).prop('disabled', true/false);

Another possibility is that you do not have the XIB included in your Build target (which is what happened to me).

This could happen if you have a different target for Dev, Test & Release Builds (which you should have anyway).

The solution posted here does not work for me. Therefore, I am posting this answer to help someone facing similar issue.

OS: Ubuntu 18
PostgreSQL: 9.5 (Hosted on Ubuntu)
Docker: Server Application (which connects to PostgreSQL)

I am using docker-compose.yml to build application.

STEP 1: Please add host.docker.internal:<docker0 IP>

version: '3'
services:
  bank-server:
    ...
    depends_on:
      ....
    restart: on-failure
    ports:
      - 9090:9090
    extra_hosts:
      - "host.docker.internal:172.17.0.1"

To find IP of docker i.e. 172.17.0.1 (in my case) you can use:

$> ifconfig docker0
docker0: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500
        inet 172.17.0.1  netmask 255.255.0.0  broadcast 172.17.255.255

OR

$> ip a
1: docker0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN group default
    inet 172.17.0.1/16 brd 172.17.255.255 scope global docker0
       valid_lft forever preferred_lft forever

STEP 2: In postgresql.conf, change listen_addresses to listen_addresses = '*'

STEP 3: In pg_hba.conf, add this line

host    all             all             0.0.0.0/0               md5

STEP 4: Now restart postgresql service using, sudo service postgresql restart

STEP 5: Please use host.docker.internal hostname to connect database from Server Application.
Ex: jdbc:postgresql://host.docker.internal:5432/bankDB

Enjoy!!

Thanks to this guys I did it http://highoncoding.com/Articles/848_Creating_iPad_Dashboard_Using_UIViewController_Containment.aspx

Add UIView, connect it to header:

@property (weak, nonatomic) IBOutlet UIView *addViewToAddPlot;

In - (void)viewDidLoad do this:

ViewControllerToAdd *nonSystemsController = [[ViewControllerToAdd alloc] initWithNibName:@"ViewControllerToAdd" bundle:nil];
    nonSystemsController.view.frame = self.addViewToAddPlot.bounds;
    [self.addViewToAddPlot addSubview:nonSystemsController.view];
    [self addChildViewController:nonSystemsController];
    [nonSystemsController didMoveToParentViewController:self];

Enjoy

Use the following instead:

boost::function<void (int)> f2( boost::bind( &myclass::fun2, this, _1 ) );

This forwards the first parameter passed to the function object to the function using place-holders - you have to tell Boost.Bind how to handle the parameters. With your expression it would try to interpret it as a member function taking no arguments.
See e.g. here or here for common usage patterns.

Note that VC8s cl.exe regularly crashes on Boost.Bind misuses - if in doubt use a test-case with gcc and you will probably get good hints like the template parameters Bind-internals were instantiated with if you read through the output.

I think when you can follow the same or similar design patterns as a true OO language like Java/C#, you can pretty much call it an OO language. Some aspects are obviously different but you can still use very well established OO design pattersn.

Check whether your template in theme folder contains search.php and searchform.php or not.

sudo mkdir -p /usr/local/include /usr/local/lib /usr/local/sbin

sudo chown -R $(whoami) /usr/local/include /usr/local/lib /usr/local/sbin

This will create all required directories and give it the correct ownership.

After running these commands check with: brew doctor

This works for Mojave.

Try this:

 <html>
    <head>
        <style>
            select {
              height: 30px;
              color: #0000ff;
            }
        </style>
    </head>
    <body>
        <table>
            <tbody>
                <tr>
                    <td>
                        <select name="test">
                            <option value="Basic">Basic : $30.00 USD - yearly</option>
                            <option value="Sustaining">Sustaining : $60.00 USD - yearly</option>
                            <option value="Supporting">Supporting : $120.00 USD - yearly</option>
                        </select>
                    </td>
                </tr>
            </tbody>
        </table>
    </body>
</html>

Not related to variables, your example will also be solved by MOD:

=Mod(VLOOKUP(A1, B:B, 1, 0);10)

You can delete everything and recreate database + seeds with both:

1. rake db:reset: loads from schema.rb
2. rake db:drop db:create db:migrate db:seed: loads from migrations

Make sure you have no connections to db (rails server, sql client..) or the db won't drop.

schema.rb is a snapshot of the current state of your database generated by:

rake db:schema:dump

What if your program does not know upfront how much memory to allocate (hence you cannot use stack variables). Say linked lists, the lists can grow without knowing upfront what is its size. So allocating on a heap makes sense for a linked list when you are not aware of how many elements would be inserted into it.

If You want to check only when scroll ended, in Vanilla JS, You can come up with a solution like this:

Super Super compact

var t
window.onresize = () => { clearTimeout(t) t = setTimeout(() => { resEnded() }, 500) }
function resEnded() { console.log('ended') }

All 3 possible combinations together (ES6)

var t
window.onresize = () => {
    resizing(this, this.innerWidth, this.innerHeight) //1
    if (typeof t == 'undefined') resStarted() //2
    clearTimeout(t); t = setTimeout(() => { t = undefined; resEnded() }, 500) //3
}

function resizing(target, w, h) {
    console.log(`Youre resizing: width ${w} height ${h}`)
}    
function resStarted() { 
    console.log('Resize Started') 
}
function resEnded() { 
    console.log('Resize Ended') 
}

Yes. You can use Console of Sublime with (Linux):

Ctrl + `

And type:

view.settings().get('font_face')

Get any setting the same way.

There are several ways I can think of to do this.

Use a callback:

 function FunctInit(someVarible){
      //init and fill screen
      AndroidCallGetResult();  // Enables Android button.
 }

 function getResult(){ // Called from Android button only after button is enabled
      //return some variables
 }

Use a Timeout (this would probably be my preference):

 var inited = false;
 function FunctInit(someVarible){
      //init and fill screen
      inited = true;
 }

 function getResult(){
      if (inited) {
           //return some variables
      } else {
           setTimeout(getResult, 250);
      }
 }

Wait for the initialization to occur:

 var inited = false;
 function FunctInit(someVarible){
      //init and fill screen
      inited = true;
 }

 function getResult(){
      var a = 1;
      do { a=1; }
      while(!inited);
      //return some variables
 }

Checking out Tags

If you want to view the versions of files a tag is pointing to, you can do a git checkout, though this puts your repository in “detached HEAD” state, which has some ill side effects:

$ git checkout 2.0.0
Note: checking out '2.0.0'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:

  git checkout -b <new-branch-name>

HEAD is now at 99ada87... Merge pull request #89 from schacon/appendix-final

$ git checkout 2.0-beta-0.1
Previous HEAD position was 99ada87... Merge pull request #89 from schacon/appendix-final
HEAD is now at df3f601... add atlas.json and cover image

In “detached HEAD” state, if you make changes and then create a commit, the tag will stay the same, but your new commit won’t belong to any branch and will be unreachable, except for by the exact commit hash. Thus, if you need to make changes—say you’re fixing a bug on an older version, for instance—you will generally want to create a branch:

$ git checkout -b version2 v2.0.0
Switched to a new branch 'version2'

If you do this and make a commit, your version2 branch will be slightly different than your v2.0.0 tag since it will move forward with your new changes, so do be careful.

Most people are using gson : check this

Gson gson = new Gson();
String json = gson.toJson(myObj);

Just want to open the app through browser? You can achieve it using below code:

HTML:

<a href="intent:#Intent;action=packageName;category=android.intent.category.DEFAULT;category=android.intent.category.BROWSABLE;end">Click here</a>

Manifest:

<intent-filter>
      <action android:name="packageName" />
      <category android:name="android.intent.category.DEFAULT" />
      <category android:name="android.intent.category.BROWSABLE" />
</intent-filter>

This intent filter should be in Launcher Activity.

If you want to pass the data on click of browser link, just refer this link.

If you are using windows version nginx, you can try to kill all nginx process and restart it to see. I encountered same issue In my environment, but resolved it with this solution.

This is going to return the keys with max value in a Map<Integer, Integer>

public Set<Integer> getMaxKeys(Map<Integer, Integer> map) { 

        if (map.isEmpty()) {
            return Collections.emptySet();
        }

        return map
        .entrySet()
        .stream()
        .collect(
            groupingBy(
                Map.Entry::getValue, TreeMap::new, mapping(Map.Entry::getKey, toSet())
            )
         )
         .lastEntry()
         .getValue();
    }

I know, this is not really a solution for your question, because you ask for

display + opacity

My approach solves a more general question, but maybe this was the background problem that should be solved by using display in combination with opacity.

My desire was to get the Element out of the way when it is not visible. This solution does exactly that: It moves the element out of the away, and this can be used for transition:

.child {
  left: -2000px;
  opacity: 0;
  visibility: hidden;
  transition: left 0s 0.8s, visibility 0s 0.8s, opacity 0.8s;
}

.parent:hover .child {
  left: 0;
  opacity: 1;
  visibility: visible;
  transition: left 0s, visibility 0s, opacity 0.8s;
}

This code does not contain any browser prefixes or backward compatibility hacks. It just illustrates the concept how the element is moved away as it is not needed any more.

The interesting part are the two different transition definitions. When the mouse-pointer is hovering the .parent element the .child element needs to be put in place immediately and then the opacity will be changed:

transition: left 0s, visibility 0s, opacity 0.8s;

When there is no hover, or the mouse-pointer was moved off the element, one has to wait until the opacity change has finished before the element can be moved off screen:

transition: left 0s 0.8s, visibility 0s 0.8s, opacity 0.8s;

Moving the object away will be a viable alternative in a case where setting display:none would not break the layout.

I hope I hit the nail on the head for this question although I did not answer it.

I also had this issue with Visual Studio 2015, tried everything I could read about but in the end all that was left was a clean install. I used Microsofts tool VisualStudioUninstaller to get rid of every component.

https://github.com/Microsoft/VisualStudioUninstaller

Usage:

1. Extract TotalUninstaller.zip
2. Open an administrator command prompt.
3. Execute Setup.ForcedUninstall.exe
4. Type 'Y' to uninstall.

After reinstall everything worked normally again. I did not experience lag in every project but one was causing enough pain so I really had no choice.

Read about another command that you can also try but I know VisualStudioUninstaller works, at least it did for me.

D:\vs_ultimate.exe /uninstall /force

Where D: is the location of your installation media (mounted iso, etc).

if i understood you can do the following

Right Click on View Name in SQL Server Management Studio -> Script View As ->CREATE To ->New Query Window

import networkx as nx
import matplotlib.pyplot as plt

G = nx.DiGraph()
G.add_node("A")
G.add_node("B")
G.add_node("C")
G.add_node("D")
G.add_node("E")
G.add_node("F")
G.add_node("G")
G.add_edge("A","B")
G.add_edge("B","C")
G.add_edge("C","E")
G.add_edge("C","F")
G.add_edge("D","E")
G.add_edge("F","G")

print(G.nodes())
print(G.edges())

pos = nx.spring_layout(G)

nx.draw_networkx_nodes(G, pos)
nx.draw_networkx_labels(G, pos)
nx.draw_networkx_edges(G, pos, edge_color='r', arrows = True)

plt.show()

Late response, but I think it will help others.

Part of imitating system("pause") is imitating what it asks the user to do: "Press any key to continue . . . " So, we need something that does not wait for simply a return as std::cin.get() would do. Even getch() has its problems when used twice (the second time call has been noticed to skip pausing generally if it's immediately paused again afterwards on the same key press). I think it has to do with the input buffer. System("pause") is usually not recommended, but we still need something to imitate what users might already expect. I prefer getch() because it doesn't echo to the screen, and it works dynamically.

The solution is to do the following using a do-while loop:

void Console::pause()
{ 
    int ch = 0;

    std::cout << "\nPress any key to continue . . . ";

    do {
        ch = getch();
    } while (ch != 0);

    std::cout << std::endl;
} 

Now it waits for the user to press any key. If it's used twice, it waits for the user again instead of skipping.

You might sort the helper[] array directly:

java.util.Arrays.sort(helper, 1, helper.length);

Sorts the array from index 1 to the end. Leaves the first item at index 0 untouched.

See Arrays.sort(Object[] a, int fromIndex, int toIndex)

I usually do it the way that you are doing it (i.e. sudo -u username command). But, there is also the 'djb' way to run a daemon with privileges of another user. See: http://thedjbway.b0llix.net/daemontools/uidgid.html

This can not be done purely with css. This is a behaviour, which affects the styling of the page.

With jquery you can quickly implement the behavior from your question:

$(function() {
  $('#a').hover(function() {
    $('#b').css('background-color', 'yellow');
  }, function() {
    // on mouseout, reset the background colour
    $('#b').css('background-color', '');
  });
});

JohannesD's answer is correct, but I feel it isn't entirely clear on an aspect of the problem.

The example he gives declares and initializes the variable i in case 1, and then tries to use it in case 2. His argument is that if the switch went straight to case 2, i would be used without being initialized, and this is why there's a compilation error. At this point, one could think that there would be no problem if variables declared in a case were never used in other cases. For example:

switch(choice) {
    case 1:
        int i = 10; // i is never used outside of this case
        printf("i = %d\n", i);
        break;
    case 2:
        int j = 20; // j is never used outside of this case
        printf("j = %d\n", j);
        break;
}

One could expect this program to compile, since both i and j are used only inside the cases that declare them. Unfortunately, in C++ it doesn't compile: as Ciro Santilli ???? ???? ??? explained, we simply can't jump to case 2:, because this would skip the declaration with initialization of i, and even though case 2 doesn't use i at all, this is still forbidden in C++.

Interestingly, with some adjustments (an #ifdef to #include the appropriate header, and a semicolon after the labels, because labels can only be followed by statements, and declarations do not count as statements in C), this program does compile as C:

// Disable warning issued by MSVC about scanf being deprecated
#ifdef _MSC_VER
#define _CRT_SECURE_NO_WARNINGS
#endif

#ifdef __cplusplus
#include <cstdio>
#else
#include <stdio.h>
#endif

int main() {

    int choice;
    printf("Please enter 1 or 2: ");
    scanf("%d", &choice);

    switch(choice) {
        case 1:
            ;
            int i = 10; // i is never used outside of this case
            printf("i = %d\n", i);
            break;
        case 2:
            ;
            int j = 20; // j is never used outside of this case
            printf("j = %d\n", j);
            break;
    }
}

Thanks to an online compiler like http://rextester.com you can quickly try to compile it either as C or C++, using MSVC, GCC or Clang. As C it always works (just remember to set STDIN!), as C++ no compiler accepts it.

If you have lists that are not the same length, you may not want to use zip as per Patricks answer. This works:

>>> zip(*[('a', 1), ('b', 2), ('c', 3), ('d', 4)])
[('a', 'b', 'c', 'd'), (1, 2, 3, 4)]

But with different length lists, zip truncates each item to the length of the shortest list:

>>> zip(*[('a', 1), ('b', 2), ('c', 3), ('d', 4), ('e', )])
[('a', 'b', 'c', 'd', 'e')]

You can use map with no function to fill empty results with None:

>>> map(None, *[('a', 1), ('b', 2), ('c', 3), ('d', 4), ('e', )])
[('a', 'b', 'c', 'd', 'e'), (1, 2, 3, 4, None)]

zip() is marginally faster though.

define() is part of the AMD spec of js

See:

• https://github.com/amdjs/amdjs-api/wiki/AMD

Edit: Also see Claudio's answer below. Likely the more relevant explanation.

Stopping Event Propagation in some particular elements ma y become dangerous as it may prevent other some scripts from running. So check whether the triggering is from the excluded area from inside the function.

$(document).on('click', function(event) {
  if (!$(event.target).closest('#menucontainer').length) {
    // Hide the menus.
  }
});

Here function is initiated when clicking on document, but it excludes triggering from #menucontainer. For details https://css-tricks.com/dangers-stopping-event-propagation/

MAX_FILE_SIZE is in KB not bytes. You were right, it is in bytes. So, for a limit of 4MB convert 4MB in bytes {1024 * (1024 * 4)} try:

<input type="hidden" name="MAX_FILE_SIZE" value="4194304" /> 

Update 1

As explained by others, you will never get a warning for this. It's there just to impose a soft limit on server side.

Update 2

To answer your sub-question. Yes, there is a difference, you NEVER trust the user input. If you want to always impose a limit, you always must check its size. Don't trust what MAX_FILE_SIZE does, because it can be changed by a user. So, yes, you should check to make sure it's always up to or above the size you want it to be.

The difference is that if you have imposed a MAX_FILE_SIZE of 2MB and the user tries to upload a 4MB file, once they reach roughly the first 2MB of upload, the transfer will terminate and the PHP will stop accepting more data for that file. It will report the error on the files array.

Try this:

mynewlist = [s for s in mylist if s.isdigit()]

From the docs:

str.isdigit()

Return true if all characters in the string are digits and there is at least one character, false otherwise.

For 8-bit strings, this method is locale-dependent.

As noted in the comments, isdigit() returning True does not necessarily indicate that the string can be parsed as an int via the int() function, and it returning False does not necessarily indicate that it cannot be. Nevertheless, the approach above should work in your case.

please, something went xxx*x, and that's not true at all, check that

if you are inside the actual function, you can use arguments.callee as a reference to the function. as in:

button.addEventListener('click', function() {
      ///this will execute only once
      alert('only once!');
      this.removeEventListener('click', arguments.callee);
});

EDIT: This will not work if you are working in strict mode ("use strict";)

Try doubling up the single quotes (many databases expect it that way), so it would be :

INSERT INTO table_name (field1, field2) VALUES (123, 'Hello there''s');

Relevant quote from the documentation:

A string constant is formed by enclosing the string in single quotes ('). A single quote within the string can be encoded by putting two single quotes in a row - as in Pascal. C-style escapes using the backslash character are not supported because they are not standard SQL. BLOB literals are string literals containing hexadecimal data and preceded by a single "x" or "X" character. ... A literal value can also be the token "NULL".

document.addEventListener('dblclick', (event) => {
    event.preventDefault()
}, { passive: false });

JDK >= 1.8

I agree with all the answers above. There is also a nice way with Java 8 Streams:

int[] subArr = IntStream.range(startInclusive, endExclusive)
                        .map(i -> src[i])
                        .toArray();

The benefit about this is, it can be useful for many different types of "src" array and helps to improve writing pipeline operations on the stream.

Not particular about this question, but for example, if the source array was double[] and we wanted to take average() of the sub-array:

double avg = IntStream.range(startInclusive, endExclusive)
                    .mapToDouble(index -> src[index])
                    .average()
                    .getAsDouble();

See my article. I had the same problem - LazyInitializationException - and here's the answer I finally came up with:
http://community.jboss.org/wiki/LazyInitializationExceptionovercome
Setting lazy=false is not the answer - it can load everything all at once, and that's not necessarily good. Example:
1 record table A references:
5 records table B references:
25 records table C references:
125 records table D
...
etc. This is but one example of what can go wrong.

That means that the definition of your function is not present in your program. You forgot to add that one.cpp to your program.

What "to add" means in this case depends on your build environment and its terminology. In MSVC (since you are apparently use MSVC) you'd have to add one.cpp to the project.

In more practical terms, applicable to all typical build methodologies, when you link you program, the object file created form one.cpp is missing.

You can easily add multiple classes to divs... So:

<div class="myclass myclass-one"></div>
<div class="myclass myclass-two"></div>
<div class="myclass myclass-three"></div>

Then in the CSS call to the share class to apply the same styles:

.myclass {...}

And you can still use your other classes like this:

.myclass-three {...}

Or if you want to be more specific in the CSS like this:

.myclass.myclass-three {...}

There are already multiple answers and formatting types for SQL server 2008. But this method somewhat ambiguous and it would be difficult for you to remember the number with respect to Specific Date Format. That's why in next versions of SQL server there is better option.

If you are using SQL Server 2012 or above versions, you should use Format() function

FORMAT ( value, format [, culture ] )

With culture option, you can specify date as per your viewers.

DECLARE @d DATETIME = '10/01/2011';
SELECT FORMAT ( @d, 'd', 'en-US' ) AS 'US English Result'
      ,FORMAT ( @d, 'd', 'en-gb' ) AS 'Great Britain English Result'
      ,FORMAT ( @d, 'd', 'de-de' ) AS 'German Result'
      ,FORMAT ( @d, 'd', 'zh-cn' ) AS 'Simplified Chinese (PRC) Result'; 
  
SELECT FORMAT ( @d, 'D', 'en-US' ) AS 'US English Result'
      ,FORMAT ( @d, 'D', 'en-gb' ) AS 'Great Britain English Result'
      ,FORMAT ( @d, 'D', 'de-de' ) AS 'German Result'
      ,FORMAT ( @d, 'D', 'zh-cn' ) AS 'Chinese (Simplified PRC) Result';

US English Result Great Britain English Result  German Result Simplified Chinese (PRC) Result

10/1/2011         01/10/2011                    01.10.2011    2011/10/1

For OP's solution, we can use following format, which is already mentioned by @Martin Smith:

FORMAT(GETDATE(), 'dd/MMM/yyyy', 'en-us')

Some sample date formats:

If you want more date formats of SQL server, you should visit:

jQuery 1.4 has a new feature for doing this, and it rules. I've forgotten what it's called, but you use it like this:

$("a.directions-link").attr("href", function(i, href) {
  return href + '?q=testing';
});

That loops over all the elements too, so no need for $.each

If you want to change all columns names, try df.toDF(*cols)

The + operator returns the numeric representation of the object. So in your particular case, it would appear to be predicating the if on whether or not d is a non-zero number.

Reference here. And, as pointed out in comments, here.

JSON.NET to the rescue.

You serialize it to JSON to persist in the Database and Deserialize it to reconstitute the .NET collection. This seems to perform better than I expected it to with Entity Framework 6 & SQLite. I know you asked for List<string> but here's an example of an even more complex collection that works just fine.

I tagged the persisted property with [Obsolete] so it would be very obvious to me that "this is not the property you are looking for" in the normal course of coding. The "real" property is tagged with [NotMapped] so Entity framework ignores it.

(unrelated tangent): You could do the same with more complex types but you need to ask yourself did you just make querying that object's properties too hard for yourself? (yes, in my case).

using Newtonsoft.Json;
....
[NotMapped]
public Dictionary<string, string> MetaData { get; set; } = new Dictionary<string, string>();

/// <summary> <see cref="MetaData"/> for database persistence. </summary>
[Obsolete("Only for Persistence by EntityFramework")]
public string MetaDataJsonForDb
{
    get
    {
        return MetaData == null || !MetaData.Any()
                   ? null
                   : JsonConvert.SerializeObject(MetaData);
    }

    set
    {
        if (string.IsNullOrWhiteSpace(value))
           MetaData.Clear();
        else
           MetaData = JsonConvert.DeserializeObject<Dictionary<string, string>>(value);
    }
}

Small method that returns a random date as string, based on some simple input parameters. Built based on variations from the above answers:

public string RandomDate(int startYear = 1960, string outputDateFormat = "yyyy-MM-dd")
{
   DateTime start = new DateTime(startYear, 1, 1);
   Random gen = new Random(Guid.NewGuid().GetHashCode());
   int range = (DateTime.Today - start).Days;
   return start.AddDays(gen.Next(range)).ToString(outputDateFormat);
}

One simple regular expression which would at least not reject any valid email address would be checking for something, followed by an @ sign and then something followed by a period and at least 2 somethings. It won't reject anything, but after reviewing the spec I can't find any email that would be valid and rejected.

email =~ /.+@[^@]+\.[^@]{2,}$/

Is it a .sql file or is it compressed (.zip, .gz, etc)? Compressed formats sometimes require more PHP resources so you could try uncompressing it before uploading.

However, there are other methods you can try also. If you have command-line access, just upload the file and import with the command line client mysql (once at the mysql> prompt, use databasename; then source file.sql).

Otherwise you can use the phpMyAdmin "UploadDir" feature to put the file on the server and have it appear within phpMyAdmin without having to also upload it from your local machine.

This link has information on using UploadDir and this one has some more tips and methods.

Thus far, the only way to "listen" on DOM events, like inserting or modifying Elements, was to use the such called Mutation Events. For instance

document.body.addEventListener('DOMNodeInserted', function( event ) {
    console.log('whoot! a new Element was inserted, see my event object for details!');
}, false);

Further reading on that: MDN

The Problem with Mutation Events was (is) they never really made their way into any official spec because of inconcistencies and stuff. After a while, this events were implemented in all modern browser, but they were declared as deprecated, in other words you don't want to use them.

The official replacement for the Mutation Events is the MutationObserver() object.

Further reading on that: MDN

The syntax at present looks like

var observer = new MutationObserver(function( mutations ) {
    mutations.forEach(function( mutation ) {
         console.log( mutation.type );
    }); 
});

var config = { childList: true };

observer.observe( document.body, config );

At this time, the API has been implemented in newer Firefox, Chrome and Safari versions. I'm not sure about IE and Opera. So the tradeoff here is definitely that you can only target for topnotch browsers.

You get this error, despite everything being in line, because of a conflict caused by one of the packages that are currently loaded in your R environment.

So, to solve this issue, detach all the packages that are not needed from the R environment. For example, when I had the same issue, I did the following:

detach(package:neuralnet)

bottom line: detach all the libraries no longer needed for execution... and the problem will be solved.

Maybe all other answers are for angular 2.X.

Now it doesn't work for angular 5.X. I'm working with it.

with only NavigationEnd, you can not get previous url.

because Router works from "NavigationStart", "RoutesRecognized",..., to "NavigationEnd".

You can check with

    router.events.forEach((event) => {
  console.log(event);
});

But still you can not get previous url even with "NavigationStart".

Now you need to use pairwise.

import 'rxjs/add/operator/filter';
import 'rxjs/add/operator/pairwise';

constructor(private router: Router) {
  this.router.events
    .filter(e => e instanceof RoutesRecognized)
    .pairwise()
    .subscribe((event: any[]) => {
      console.log(event[0].urlAfterRedirects);
    });
}
    

With pairwise, You can see what url is from and to.

"RoutesRecognized" is the changing step from origin to target url.

so filter it and get previous url from it.

Last but not least,

put this code in parent component or higher (ex, app.component.ts)

because this code fires after finish routing.

Update angular 6+

The events.filter gives error because filter is not part of events, so change the code to

import { filter, pairwise } from 'rxjs/operators';

this.router.events
.pipe(filter((evt: any) => evt instanceof RoutesRecognized), pairwise())
.subscribe((events: RoutesRecognized[]) => {
  console.log('previous url', events[0].urlAfterRedirects);
  console.log('current url', events[1].urlAfterRedirects);
});

This probably harks from the old VB NOT .Net days when bool.ToString produced True or False.

simplexml_load_file() interprets an XML file (either a file on your disk or a URL) into an object. What you have in $feed is a string.

You have two options:

• Use file_get_contents() to get the XML feed as a string, and use e simplexml_load_string():

  $feed = file_get_contents('...');
  $items = simplexml_load_string($feed);
  

• Load the XML feed directly using simplexml_load_file():

  $items = simplexml_load_file('...');
  

There is some problem for Tapas Bose code and Thomas code. If time differen?e is negative, array gets the negative values. For example if

LocalDateTime toDateTime = LocalDateTime.of(2014, 9, 10, 6, 46, 45);
LocalDateTime fromDateTime = LocalDateTime.of(2014, 9, 9, 7, 46, 45);

it returns 0 years 0 months 1 days -1 hours 0 minutes 0 seconds.

I think the right output is: 0 years 0 months 0 days 23 hours 0 minutes 0 seconds.

I propose to separate the LocalDateTime instances on LocalDate and LocalTime instances. After that we can obtain the Java 8 Period and Duration instances. The Duration instance is separated on the number of days and throughout-the-day time value (< 24h) with subsequent correction of the period value. When the second LocalTime value is before the firstLocalTime value, it is necessary to reduce the period for one day.

Here's my way to calculate the LocalDateTime difference:

private void getChronoUnitForSecondAfterFirst(LocalDateTime firstLocalDateTime, LocalDateTime secondLocalDateTime, long[] chronoUnits) {
    /*Separate LocaldateTime on LocalDate and LocalTime*/
    LocalDate firstLocalDate = firstLocalDateTime.toLocalDate();
    LocalTime firstLocalTime = firstLocalDateTime.toLocalTime();

    LocalDate secondLocalDate = secondLocalDateTime.toLocalDate();
    LocalTime secondLocalTime = secondLocalDateTime.toLocalTime();

    /*Calculate the time difference*/
    Duration duration = Duration.between(firstLocalDateTime, secondLocalDateTime);
    long durationDays = duration.toDays();
    Duration throughoutTheDayDuration = duration.minusDays(durationDays);
    Logger.getLogger(PeriodDuration.class.getName()).log(Level.INFO,
            "Duration is: " + duration + " this is " + durationDays
            + " days and " + throughoutTheDayDuration + " time.");

    Period period = Period.between(firstLocalDate, secondLocalDate);

    /*Correct the date difference*/
    if (secondLocalTime.isBefore(firstLocalTime)) {
        period = period.minusDays(1);
        Logger.getLogger(PeriodDuration.class.getName()).log(Level.INFO,
                "minus 1 day");
    }

    Logger.getLogger(PeriodDuration.class.getName()).log(Level.INFO,
            "Period between " + firstLocalDateTime + " and "
            + secondLocalDateTime + " is: " + period + " and duration is: "
            + throughoutTheDayDuration
            + "\n-----------------------------------------------------------------");

    /*Calculate chrono unit values and  write it in array*/
    chronoUnits[0] = period.getYears();
    chronoUnits[1] = period.getMonths();
    chronoUnits[2] = period.getDays();
    chronoUnits[3] = throughoutTheDayDuration.toHours();
    chronoUnits[4] = throughoutTheDayDuration.toMinutes() % 60;
    chronoUnits[5] = throughoutTheDayDuration.getSeconds() % 60;
}

The above method can be used to calculate the difference of any local date and time values, for example:

public long[] getChronoUnits(String firstLocalDateTimeString, String secondLocalDateTimeString) {
    DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss");

    LocalDateTime firstLocalDateTime = LocalDateTime.parse(firstLocalDateTimeString, formatter);
    LocalDateTime secondLocalDateTime = LocalDateTime.parse(secondLocalDateTimeString, formatter);

    long[] chronoUnits = new long[6];
    if (secondLocalDateTime.isAfter(firstLocalDateTime)) {
        getChronoUnitForSecondAfterFirst(firstLocalDateTime, secondLocalDateTime, chronoUnits);
    } else {
        getChronoUnitForSecondAfterFirst(secondLocalDateTime, firstLocalDateTime, chronoUnits);
    }
    return chronoUnits;
}

It is convenient to write a unit test for the above method (both of them are PeriodDuration class members). Here's the code:

@RunWith(Parameterized.class)
public class PeriodDurationTest {

private final String firstLocalDateTimeString;
private final String secondLocalDateTimeString;
private final long[] chronoUnits;

public PeriodDurationTest(String firstLocalDateTimeString, String secondLocalDateTimeString, long[] chronoUnits) {
    this.firstLocalDateTimeString = firstLocalDateTimeString;
    this.secondLocalDateTimeString = secondLocalDateTimeString;
    this.chronoUnits = chronoUnits;
}

@Parameters
public static Collection<Object[]> periodValues() {
    long[] chronoUnits0 = {0, 0, 0, 0, 0, 0};
    long[] chronoUnits1 = {0, 0, 0, 1, 0, 0};
    long[] chronoUnits2 = {0, 0, 0, 23, 0, 0};
    long[] chronoUnits3 = {0, 0, 0, 1, 0, 0};
    long[] chronoUnits4 = {0, 0, 0, 23, 0, 0};
    long[] chronoUnits5 = {0, 0, 1, 23, 0, 0};
    long[] chronoUnits6 = {29, 8, 24, 12, 0, 50};
    long[] chronoUnits7 = {29, 8, 24, 12, 0, 50};
    return Arrays.asList(new Object[][]{
        {"2015-09-09 21:46:44", "2015-09-09 21:46:44", chronoUnits0},
        {"2015-09-09 21:46:44", "2015-09-09 22:46:44", chronoUnits1},
        {"2015-09-09 21:46:44", "2015-09-10 20:46:44", chronoUnits2},
        {"2015-09-09 21:46:44", "2015-09-09 20:46:44", chronoUnits3},
        {"2015-09-10 20:46:44", "2015-09-09 21:46:44", chronoUnits4},
        {"2015-09-11 20:46:44", "2015-09-09 21:46:44", chronoUnits5},
        {"1984-12-16 07:45:55", "2014-09-09 19:46:45", chronoUnits6},
        {"2014-09-09 19:46:45", "1984-12-16 07:45:55", chronoUnits6}
    });
}

@Test
public void testGetChronoUnits() {
    PeriodDuration instance = new PeriodDuration();
    long[] expResult = this.chronoUnits;
    long[] result = instance.getChronoUnits(this.firstLocalDateTimeString, this.secondLocalDateTimeString);
    assertArrayEquals(expResult, result);
}

}

All tests are successful whether or not the value of the first LocalDateTime is before and for any LocalTime values.

Add the -v option to your grep command to invert the results.

Since you say you're using Java 5, you can use setInt with an Integer due to autounboxing: pstmt.setInt(1, tempID) should work just fine. In earlier versions of Java, you would have had to call .intValue() yourself.

The opposite works as well... assigning an int to an Integer will automatically cause the int to be autoboxed using Integer.valueOf(int).

I set the opacity to 0. This made it disappear but still function when you click on it.

cout << fixed << setprecision(2) << total;

setprecision specifies the minimum precision. So

cout << setprecision (2) << 1.2; 

will print 1.2

fixed says that there will be a fixed number of decimal digits after the decimal point

cout << setprecision (2) << fixed << 1.2;

will print 1.20

An engineered way to solve this if you already have files you need to push to Github/Server:

1. In Github/Server where your repo will live:

   • Create empty Git Repo (Save <YourPathAndRepoName>)
   • $git init --bare

2. Local Computer (Just put in any folder):

   • $touch .gitignore
   • (Add files you want to ignore in text editor to .gitignore)

   • $git clone <YourPathAndRepoName>

   • (This will create an empty folder with your Repo Name from Github/Server)

   • (Legitimately copy and paste all your files from wherever and paste them into this empty Repo)

   • $git add . && git commit -m "First Commit"

   • $git push origin master

Thanks RBarry. I'm putting together an IP block allocation system and storing as binary is the only way to go.

I'm storing the CIDR representation (ex: 192.168.1.0/24) of the IP block in a varchar field, and using 2 calculated fields to hold the binary form of the start and end of the block. From there, I can run fast queries to see if a given block as already been allocated or is free to assign.

I modified your function to calculate the ending IP Address like so:

CREATE FUNCTION dbo.fnDisplayIPv4End(@block AS VARCHAR(18)) RETURNS BINARY(4)
AS
BEGIN
    DECLARE @bin AS BINARY(4)
    DECLARE @ip AS VARCHAR(15)
    DECLARE @size AS INT

    SELECT @ip = Left(@block, Len(@block)-3)
    SELECT @size = Right(@block, 2)

    SELECT @bin = CAST( CAST( PARSENAME( @ip, 4 ) AS INTEGER) AS BINARY(1))
                + CAST( CAST( PARSENAME( @ip, 3 ) AS INTEGER) AS BINARY(1))
                + CAST( CAST( PARSENAME( @ip, 2 ) AS INTEGER) AS BINARY(1))
                + CAST( CAST( PARSENAME( @ip, 1 ) AS INTEGER) AS BINARY(1))

    SELECT @bin = CAST(@bin + POWER(2, 32-@size) AS BINARY(4))
    RETURN @bin
END;
go

You're looking for the <iframe> tag, or, better yet, a server-side templating language.

You don't make it clear whether you're trying to modify the Querystring in place in the Request object. Since that property is read-only, I guess we'll assume you just want to mess with the string.

... In which case, it's borderline trivial.

• grab the querystring off the Request
• .split() it on '&'
• put it back together into a new string, while sniffing for and tossing out anything starting with "language"

As of API 21, you could also use:

   ResourcesCompat.getDrawable(getResources(), R.drawable.name, null);

Instead of ContextCompat.getDrawable(context, android.R.drawable.ic_dialog_email)

You can you the distinct keyword in you criteria builder like this.

CriteriaBuilder builder = session.getCriteriaBuilder();
CriteriaQuery<Orders> query = builder.createQuery(Orders.class);
Root<Orders> root = query.from(Orders.class);
query.distinct(true).multiselect(root.get("cust_email").as(String.class));

And create the field constructor in your model class.

Short answer

These detailed explanations are great, but the OP's (and my) confusion could be resolved with one sentence: "Direct DNS to your GitHub username or organization, ignoring the specific project, and add the appropriate CNAME files in your project repositories: GitHub will send the right DNS to the right project based on files in the respository."

USe this function for date comparison in javascript:

    function fn_DateCompare(DateA, DateB) {
      var a = new Date(DateA);
      var b = new Date(DateB);

      var msDateA = Date.UTC(a.getFullYear(), a.getMonth()+1, a.getDate());
      var msDateB = Date.UTC(b.getFullYear(), b.getMonth()+1, b.getDate());

      if (parseFloat(msDateA) < parseFloat(msDateB))
        return -1;  // less than
      else if (parseFloat(msDateA) == parseFloat(msDateB))
        return 0;  // equal
      else if (parseFloat(msDateA) > parseFloat(msDateB))
        return 1;  // greater than
      else
        return null;  // error
  }

No you don't have to put credentials, You have to put headers on client side eg:

 $http({
        url: 'url of service',
        method: "POST",
        data: {test :  name },
        withCredentials: true,
        headers: {
                    'Content-Type': 'application/json; charset=utf-8'
        }
    });

And and on server side you have to put headers to this is example for nodejs:

/**
 * On all requests add headers
 */
app.all('*', function(req, res,next) {


    /**
     * Response settings
     * @type {Object}
     */
    var responseSettings = {
        "AccessControlAllowOrigin": req.headers.origin,
        "AccessControlAllowHeaders": "Content-Type,X-CSRF-Token, X-Requested-With, Accept, Accept-Version, Content-Length, Content-MD5,  Date, X-Api-Version, X-File-Name",
        "AccessControlAllowMethods": "POST, GET, PUT, DELETE, OPTIONS",
        "AccessControlAllowCredentials": true
    };

    /**
     * Headers
     */
    res.header("Access-Control-Allow-Credentials", responseSettings.AccessControlAllowCredentials);
    res.header("Access-Control-Allow-Origin",  responseSettings.AccessControlAllowOrigin);
    res.header("Access-Control-Allow-Headers", (req.headers['access-control-request-headers']) ? req.headers['access-control-request-headers'] : "x-requested-with");
    res.header("Access-Control-Allow-Methods", (req.headers['access-control-request-method']) ? req.headers['access-control-request-method'] : responseSettings.AccessControlAllowMethods);

    if ('OPTIONS' == req.method) {
        res.send(200);
    }
    else {
        next();
    }


});

HashMap - and the underlying data structure - hash tables, do not have a notion of position. Unlike a LinkedList or Vector, the input key is transformed to a 'bucket' where the value is stored. These buckets are not ordered in a way that makes sense outside the HashMap interface and as such, the items you put into the HashMap are not in order in the sense that you would expect with the other data structures

You can edit the page in SharePoint designer, convert the List View web part to an XSLT Data View. (by right click + "Convert to XSLT Data View").
Then you can edit the XSLT - find the A tag and add an attribute target="_blank"

Here is a good starting point.

HTML:

<div class="containing-table">
    <div class="centre-align">
        <div class="content"></div>
    </div>
</div>

CSS:

.containing-table {
    display: table;
    width: 100%;
    height: 400px; /* for demo only */
    border: 1px dotted blue;
}
.centre-align {
    padding: 10px;
    border: 1px dashed gray;
    display: table-cell;
    text-align: center;
    vertical-align: middle;
}
.content {
    width: 50px;
    height: 50px;
    background-color: red;
    display: inline-block;
    vertical-align: top; /* Removes the extra white space below the baseline */
}

See demo at: http://jsfiddle.net/audetwebdesign/jSVyY/

.containing-table establishes the width and height context for .centre-align (the table-cell).

You can apply text-align and vertical-align to alter .centre-align as needed.

Note that .content needs to use display: inline-block if it is to be centered horizontally using the text-align property.

I was fed up with the slow build of android on my local machine. The way I solved this was spinning up a high-end machine on AWS and rsyncing the code from my local to the machine and compiling it over there.

I saw an immediate increase in the performance and my local system was saved from CPU hog. Check out this tool I created to help the developers speed up their terminal https://stormyapp.com

If you have objects, not structs (or strings), then you'll have to intersect their keys first, and then select objects by those keys:

var ids = list1.Select(x => x.Id).Intersect(list2.Select(x => x.Id));
var result = list1.Where(x => ids.Contains(x.Id));

In summary: I would be careful as to what code you copy. It is possible you are copying code which happens to work, rather than well chosen code.

In intnumber, parseInt is used and in floatnumber valueOf is used why so?

There is no good reason I can see. It's an inconsistent use of the APIs as you suspect.

Java is case sensitive, and there isn't any Readline() method. Perhaps you mean readLine().

DataInputStream.readLine() is deprecated in favour of using BufferedReader.readLine();

However, for your case, I would use the Scanner class.

Scanner sc = new Scanner(System.in);
int intNum = sc.nextInt();
float floatNum = sc.nextFloat();

If you want to know what a class does I suggest you have a quick look at the Javadoc.

C99 requires that when a/b is representable:

(a/b) * b + a%b shall equal a

This makes sense, logically. Right?

Let's see what this leads to:

Example A. 5/(-3) is -1

=> (-1) * (-3) + 5%(-3) = 5

This can only happen if 5%(-3) is 2.

Example B. (-5)/3 is -1

=> (-1) * 3 + (-5)%3 = -5

This can only happen if (-5)%3 is -2

From the v3 documentation (Developer's Guide > Concepts > Developing for Mobile Devices):

Android and iOS devices respect the following <meta> tag:

<meta name="viewport" content="initial-scale=1.0, user-scalable=no" />

This setting specifies that the map should be displayed full-screen and should not be resizable by the user. Note that the iPhone's Safari browser requires this <meta> tag be included within the page's <head> element.

This occurred as a result of npm not being able to access your global node_modules directory locally, running

sudo chown -R Name: /usr/local/lib/node_modules

e.g.

sudo chown -R developerayo: /usr/local/lib/node_modules

fixes the issue, now you can run the command you ran again.

Try this first, you may be passing a Null Model:

@if (Model != null && !String.IsNullOrEmpty(Model.ImageName))
{
    <label for="Image">Change picture</label>
}
else
{ 
    <label for="Image">Add picture</label>
}

Otherise, you can make it even neater with some ternary fun! - but that will still error if your model is Null.

<label for="Image">@(String.IsNullOrEmpty(Model.ImageName) ? "Add" : "Change") picture</label>

This will also work and you don't need the extra class:

#navigation li li {}

If you have a third level of LI's you may have to reset/override some of the styles they will inherit from the above selector. You can target the third level like so:

#navigation li li li {}

first-letter-to-lower () {
        str="" 
        space=" " 
        for i in $@
        do
                if [ -z $(echo $i | grep "the\|of\|with" ) ]
                then
                        str=$str"$(echo ${i:0:1} | tr  '[A-Z]' '[a-z]')${i:1}$space" 
                else
                        str=$str${i}$space 
                fi
        done
        echo $str
}
first-letter-to-upper-xc () {
        v-first-letter-to-upper | xclip -selection clipboard
}
first-letter-to-upper () {
        str="" 
        space=" " 
        for i in $@
        do
                if [ -z $(echo $i | grep "the\|of\|with" ) ]
                then
                        str=$str"$(echo ${i:0:1} | tr  '[a-z]' '[A-Z]')${i:1}$space" 
                else
                        str=$str${i}$space 
                fi
        done
        echo $str
}

first-letter-to-lower-xc(){ v-first-letter-to-lower | xclip -selection clipboard }

None of these answers worked for me.

Assuming, that you have root access on the box you can do:

sudo -u postgres psql

If that fails with a database "postgres" does not exists this block.

sudo -u postgres psql template1

Then sudo nano /etc/postgresql/11/main/pg_hba.conf file

local   all         postgres                          ident

For newer versions of PostgreSQL ident actually might be peer.

Inside the psql shell you can give the DB user postgres a password:

ALTER USER postgres PASSWORD 'newPassword';

Another approach using Fetch API with Promise

<html>
 <body>
  <div class="root" data-content="partial.html">
  <script>
      const root = document.querySelector('.root')
      const link = root.dataset.content;

I always go back to this article SQL Server 2005 XQuery and XML-DML - Part 1 to know how to use the XML features in SQL Server 2005.

For basic XPath know-how, I'd recommend the W3Schools tutorial.

The appropriate regex would be the ' char followed by any number of any chars [including zero chars] ending with an end of string/line token:

'.*$

And if you wanted to capture everything after the ' char but not include it in the output, you would use:

(?<=').*$

This basically says give me all characters that follow the ' char until the end of the line.

Edit: It has been noted that $ is implicit when using .* and therefore not strictly required, therefore the pattern:

'.* 

is technically correct, however it is clearer to be specific and avoid confusion for later code maintenance, hence my use of the $. It is my belief that it is always better to declare explicit behaviour than rely on implicit behaviour in situations where clarity could be questioned.

var t = document.getElementById("table"),
    d = t.getElementsByTagName("tr"),
    r = d.getElementsByTagName("td");

needs to be:

var t = document.getElementById("table"),
    tableRows = t.getElementsByTagName("tr"),
    r = [], i, len, tds, j, jlen;

for ( i =0, len = tableRows.length; i<len; i++) {
    tds = tableRows[i].getElementsByTagName('td');
    for( j = 0, jlen = tds.length; j < jlen; j++) {
        r.push(tds[j]);
    }
}

Because getElementsByTagName returns a NodeList an Array-like structure. So you need to loop through the return nodes and then populate you r like above.

As a simple alternative, that does not require $.when.apply or an array, you can use the following pattern to generate a single promise for multiple parallel promises:

promise = $.when(promise, anotherPromise);

e.g.

function GetSomeDeferredStuff() {
    // Start with an empty resolved promise (or undefined does the same!)
    var promise;
    var i = 1;
    for (i = 1; i <= 5; i++) {
        var count = i;

        promise = $.when(promise,
        $.ajax({
            type: "POST",
            url: '/echo/html/',
            data: {
                html: "<p>Task #" + count + " complete.",
                delay: count / 2
            },
            success: function (data) {
                $("div").append(data);
            }
        }));
    }
    return promise;
}

$(function () {
    $("a").click(function () {
        var promise = GetSomeDeferredStuff();
        promise.then(function () {
            $("div").append("<p>All done!</p>");
        });
    });
});

Notes:

• I figured this one out after seeing someone chain promises sequentially, using promise = promise.then(newpromise)
• The downside is it creates extra promise objects behind the scenes and any parameters passed at the end are not very useful (as they are nested inside additional objects). For what you want though it is short and simple.
• The upside is it requires no array or array management.

Recently when working on a web app for a client, I noticed that any click events added to a non-anchor element didn't work on the iPad or iPhone. All desktop and other mobile devices worked fine - but as the Apple products are the most popular mobile devices, it was important to get it fixed.

Turns out that any non-anchor element assigned a click handler in jQuery must either have an onClick attribute (can be empty like below):

onClick=""

OR

The element css needs to have the following declaration:

cursor:pointer

Strange, but that's what it took to get things working again!
source:http://www.mitch-solutions.com/blog/17-ipad-jquery-live-click-events-not-working

With the assumption that there's only one element:

 $("#grid_GridHeader")[0]
 $("#grid_GridHeader").get(0)
 $("#grid_GridHeader").get()

...are all equivalent, returning the single underlying element.

From the jQuery source code, you can see that get(0), under the covers, essentially does the same thing as the [0] approach:

 // Return just the object
 ( num < 0 ? this.slice(num)[ 0 ] : this[ num ] );

I was running a job which ran a shell script in Jenkins on a Windows machine. The job was failing due to the error given below. I was able to fix the error thanks to clues in Andrejz's answer.

Solution :

1 - Install Cygwin and note the directory where it gets installed.

It was C:\cygwin64 in my case. The sh.exe which is needed to run shell scripts is in the "bin" sub-directory, i.e. C:\cygwin64\bin.

2 - Tell Jenkins where sh.exe is located.

Jenkins web console > Manage Jenkins > Configure System > Under shell, set the "Shell executable" = C:\cygwin64\bin\sh.exe > Click apply & also click save.

That's all I did to make my job pass. I was running Jenkins from a war file and I did not need to restart it to make this work.

The example below is an adaptation and simplification of a longer post from We ? Swift. This is what it will look like:

Create a New Project

It can be just the usual Single View Application.

Add the Code

Replace the ViewController.swift code with the following:

import UIKit
class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
    
    // Data model: These strings will be the data for the table view cells
    let animals: [String] = ["Horse", "Cow", "Camel", "Sheep", "Goat"]
    
    // cell reuse id (cells that scroll out of view can be reused)
    let cellReuseIdentifier = "cell"
    
    // don't forget to hook this up from the storyboard
    @IBOutlet var tableView: UITableView!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // Register the table view cell class and its reuse id
        self.tableView.register(UITableViewCell.self, forCellReuseIdentifier: cellReuseIdentifier)
        
        // (optional) include this line if you want to remove the extra empty cell divider lines
        // self.tableView.tableFooterView = UIView()

        // This view controller itself will provide the delegate methods and row data for the table view.
        tableView.delegate = self
        tableView.dataSource = self
    }
    
    // number of rows in table view
    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return self.animals.count
    }
    
    // create a cell for each table view row
    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        
        // create a new cell if needed or reuse an old one
        let cell:UITableViewCell = self.tableView.dequeueReusableCell(withIdentifier: cellReuseIdentifier) as UITableViewCell!
        
        // set the text from the data model
        cell.textLabel?.text = self.animals[indexPath.row]
        
        return cell
    }
    
    // method to run when table view cell is tapped
    func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
        print("You tapped cell number \(indexPath.row).")
    }
}

Read the in-code comments to see what is happening. The highlights are

• The view controller adopts the UITableViewDelegate and UITableViewDataSource protocols.
• The numberOfRowsInSection method determines how many rows there will be in the table view.
• The cellForRowAtIndexPath method sets up each row.
• The didSelectRowAtIndexPath method is called every time a row is tapped.

Add a Table View to the Storyboard

Drag a UITableView onto your View Controller. Use auto layout to pin the four sides.

Hook up the Outlets

Control drag from the Table View in IB to the tableView outlet in the code.

Finished

That's all. You should be able run your app now.

This answer was tested with Xcode 9 and Swift 4

Variations

Row Deletion

You only have to add a single method to the basic project above if you want to enable users to delete rows. See this basic example to learn how.

Row Spacing

If you would like to have spacing between your rows, see this supplemental example.

Custom cells

The default layout for the table view cells may not be what you need. Check out this example to help get you started making your own custom cells.

Dynamic Cell Height

Sometimes you don't want every cell to be the same height. Starting with iOS 8 it is easy to automatically set the height depending on the cell content. See this example for everything you need to get you started.

In "References", import DAO 3.6 object reference.

private sub showTableData

dim db as dao.database
dim rs as dao.recordset

set db = currentDb
set rs = db.OpenRecordSet("myTable") 'myTable is a MS-Access table created previously

'populate the table
rs.movelast
rs.movefirst

do while not rs.EOF
   debug.print(rs!myField) 'myField is a field name in table myTable
   rs.movenext             'press Ctrl+G to see debuG window beneath
loop

msgbox("End of Table")

end sub

You can interate data objects like queries and filtered tables in different ways:

Trhough query:

private sub showQueryData

dim db as dao.database
dim rs as dao.recordset
dim sqlStr as string

sqlStr = "SELECT * FROM customers as c WHERE c.country='Brazil'"

set db = currentDb
set rs = db.openRecordset(sqlStr)

rs.movefirst

do while not rs.EOF
  debug.print("cust ID: " & rs!id & " cust name: " & rs!name)
  rs.movenext
loop

msgbox("End of customers from Brazil")

end sub

You should also look for "Filter" property of the recordset object to filter only the desired records and then interact with them in the same way (see VB6 Help in MS-Access code window), or create a "QueryDef" object to run a query and use it as a recordset too (a little bit more tricky). Tell me if you want another aproach.

I hope I've helped.

In python, use and instead of && like this:

#!/usr/bin/python
foo = True;
bar = True;
if foo and bar:
    print "both are true";

This prints:

both are true

Override toString() method in Student class as below:

   @Override
   public String toString() {
        return ("StudentName:"+this.getStudentName()+
                    " Student No: "+ this.getStudentNo() +
                    " Email: "+ this.getEmail() +
                    " Year : " + this.getYear());
   }

1) Should i use Double or double???

Double and double is the same thing. double is just a C# keyword working as alias for the class System.Double The most common thing is to use the aliases! The same for string (System.String), int(System.Int32)

Also see Built-In Types Table (C# Reference)

I think schemas are like a lot of new features (whether to SQL Server or any other software tool). You need to carefully evaluate whether the benefit of adding it to your development kit offsets the loss of simplicity in design and implementation.

It looks to me like schemas are roughly equivalent to optional namespaces. If you're in a situation where object names are colliding and the granularity of permissions is not fine enough, here's a tool. (I'd be inclined to say there might be design issues that should be dealt with at a more fundamental level first.)

The problem can be that, if it's there, some developers will start casually using it for short-term benefit; and once it's in there it can become kudzu.

public static byte[] toByteArray(int value) {
    byte result[] = new byte[4];
    return Conversion.intToByteArray(value, 0, result, 0, 4);
}

This worked for me

json = json.replace("\\\"","'");
JSONObject jo = new JSONObject(json.substring(1,json.length()-1));

to create an orderable class you have to override 6 special functions, so that it would be called by the min() function

these methods are__lt__ , __le__, __gt__, __ge__, __eq__ , __ne__ in order they are less than, less than or equal, greater than, greater than or equal, equal, not equal. for example you should implement __lt__ as follows:

def __lt__(self, other):
  return self.comparable_value < other.comparable_value

then you can use the min function as follows:

minValue = min(yourList, key=(lambda k: yourList[k]))

this worked for me.

If you need to work with games. As explained in this post https://www.learncodebygaming.com/blog/pyautogui-not-working-use-directinput, some games like Minecraft or Fortnite have their own way of registering mouse / keyboard events. The way to control mouse and keyboard events is by using the brand new PyDirectInput library. Their github repository is https://github.com/learncodebygaming/pydirectinput, and has a lot of great information.
Here's a quick code that does a mouse loop, and clicks:

import pydirectinput  # pip install pydirectinput


pydirectinput.moveTo(0, 500)
pydirectinput.click()

  NSDateFormatter *dateformate=[[NSDateFormatter alloc]init];
  [dateformate setDateFormat:@"yyyy"]; // Date formater
  NSString *date = [dateformate stringFromDate:[NSDate date]]; // Convert date to string
  NSLog(@"date :%@",date);

Here:

def random_color():
    rgbl=[255,0,0]
    random.shuffle(rgbl)
    return tuple(rgbl)

The result is either red, green or blue. The method is not applicable to other sets of colors though, where you'd have to build a list of all the colors you want to choose from and then use random.choice to pick one at random.

Here's another decoder that works well as of 2014: http://viewstatedecoder.azurewebsites.net/

<span style="color:orange;">orange text</span>

 WebClient wb = new WebClient();
 wb.Headers.Add(HttpRequestHeader.Cookie, "somecookie");

From Comments

How do you format the name and value of the cookie in place of "somecookie" ?

wb.Headers.Add(HttpRequestHeader.Cookie, "cookiename=cookievalue"); 

For multiple cookies:

wb.Headers.Add(HttpRequestHeader.Cookie, 
              "cookiename1=cookievalue1;" +
              "cookiename2=cookievalue2");

The XML declaration in the document map consists of the following:

The version number, ?xml version="1.0"?. 

This is mandatory. Although the number might change for future versions of XML, 1.0 is the current version.

The encoding declaration,

encoding="UTF-8"?

This is optional. If used, the encoding declaration must appear immediately after the version information in the XML declaration, and must contain a value representing an existing character encoding.

Put the modal and javascript into the partial view. Then call the partial view in your page. This will handle form submission too.

Partial View

    <div class="modal-content">
        <div class="modal-header">
            <h4 class="modal-title">Missing Service Order</h4>
        </div>
        <div class="modal-body">
            <p>You have not entered a Service Order. Do you want to continue?</p>
        </div>
        <div class="modal-footer">
            <input id="btnSubmit" type="submit" class="btn btn-primary" 
              value="Submit" href="javascript:" 
               onClick="document.getElementById('Coordinate').submit()" />
            <button type="button" class="btn btn-default" data- 
                                               dismiss="modal">Cancel</button>
        </div>
    </div>
  </div>
</div>

Javascript

  <script type="text/javascript" language="javascript">
$(document).ready(function () {
    $("#Coordinate").on('submit',
        function (e) {
            if ($("#ServiceOrder").val() == '') {
                e.preventDefault();
                $('#confirmDialog').modal('show');
               }
            });
    });
</script>

Then just call your partial inside the form of your page.

Create.cshtml

 @using (Html.BeginForm("Edit","Home",FormMethod.Post, new {id ="Coordinate"}))
 {
     //Form Code

     @Html.Partial("ConfirmDialog")

git diff branch_1..branch_2

That will produce the diff between the tips of the two branches. If you'd prefer to find the diff from their common ancestor to test, you can use three dots instead of two:

How to remove NaN (float) item(s) from a list of mixed data types

If you have mixed types in an iterable, here is a solution that does not use numpy:

from math import isnan

Z = ['a','b', float('NaN'), 'd', float('1.1024')]

[x for x in Z if not (
                      type(x) == float # let's drop all float values…
                      and isnan(x) # … but only if they are nan
                      )]

['a', 'b', 'd', 1.1024]

Short-circuit evaluation means that isnan will not be called on values that are not of type 'float', as False and (…) quickly evaluates to False without having to evaluate the right-hand side.

You probably have allProviders typed as object[] as well. And property country does not exist on object. If you don't care about typing, you can declare both allProviders and countryProviders as Array<any>:

let countryProviders: Array<any>;
let allProviders: Array<any>;

If you do want static type checking. You can create an interface for the structure and use it:

interface Provider {
    region: string,
    country: string,
    locale: string,
    company: string
}

let countryProviders: Array<Provider>;
let allProviders: Array<Provider>;

Every control that uses Collections to store data have SelectedValue, SelectedItem property. Examples of these controls are ListBox, Dropdown, RadioButtonList, CheckBoxList.

To be more specific if you literally want to retrieve Text of Selected Item then you can write:

ListBox1.SelectedItem.Text;

Your ListBox1 can also return Text using SelectedValue property if value has set to that before. But above is more effective way to get text.

Now, the value is something that is not visible to user but it is used mostly to store in database. We don't insert Text of ListBox1, however we can insert it also, but we used to insert value of selected item. To get value we can use

ListBox1.SelectedValue

The switch method (as mentioned by Guffa) works very nicely indeed. However, the default warning settings in most linters will alert you about the use of fall-through. It's one of the main reasons I use switches at all, so I pretty much ignore this warning, but you should be aware that the using the fall-through feature of the switch statement can be tricky. In cases like this, though - I'd go for it.

And the modified CSS:

.panel-heading .accordion-toggle h4:after {
    /* symbol for "opening" panels */
    font-family: 'Glyphicons Halflings';  
    content: "\e114";    
    float: right;        
    color: grey;        
    overflow: no-display;
}
.panel-heading .accordion-toggle.collapsed h4:after {
    /* symbol for "collapsed" panels */
    content: "\e080";    
}
a.accordion-toggle{
    text-decoration: none;
}

I faced this problem when I tried to pass a serializable model object. Inside that model, another model was a variable but that wasn't serializable. That's why I face this problem. Make sure all the model inside of an model is serializable.

Try:

$(this).prop( "disabled", true );

1 - You can set a timeout in your application :

var client = new YourServiceReference.YourServiceClass();
client.Timeout = 60; // or -1 for infinite

It is in milliseconds.

2 - Also you can increase timeout value in httpruntime tag in web/app.config :

<configuration>
     <system.web>
          <httpRuntime executionTimeout="<<**seconds**>>" />
          ...
     </system.web>
</configuration>

For ASP.NET applications, the Timeout property value should always be less than the executionTimeout attribute of the httpRuntime element in Machine.config. The default value of executionTimeout is 90 seconds. This property determines the time ASP.NET continues to process the request before it returns a timed out error. The value of executionTimeout should be the proxy Timeout, plus processing time for the page, plus buffer time for queues. -- Source

much easier way!

devtools::install_github("yikeshu0611/onetree") #install onetree package

library(onetree)
widedata=reshape_toWide(data = dat1,id = "name",j = "numbers",value.var.prefix = "value")
widedata

        name     value1     value2     value3     value4
   firstName  0.3407997 -0.7033403 -0.3795377 -0.7460474
  secondName -0.8981073 -0.3347941 -0.5013782 -0.1745357

if you want to go back from wide to long, only change Wide to Long, and no changes in objects.

reshape_toLong(data = widedata,id = "name",j = "numbers",value.var.prefix = "value")

        name numbers      value
   firstName       1  0.3407997
  secondName       1 -0.8981073
   firstName       2 -0.7033403
  secondName       2 -0.3347941
   firstName       3 -0.3795377
  secondName       3 -0.5013782
   firstName       4 -0.7460474
  secondName       4 -0.1745357

You need to do

Update table_xpto
set column_xpto = x.xpto_New
    ,column2 = x.column2New
from table_xpto xpto
   inner join table_xptoNew xptoNew ON xpto.bla = xptoNew.Bla
where <clause where>
