Programs & Examples On #Regex group

?: is used when you want to group an expression, but you do not want to save it as a matched/captured portion of the string.

An example would be something to match an IP address:

/(?:\d{1,3}\.){3}\d{1,3}/

Note that I don't care about saving the first 3 octets, but the (?:...) grouping allows me to shorten the regex without incurring the overhead of capturing and storing a match.

Sorry, not Swift, just a proof of concept in the closest language at hand.

// JavaScript POC. Output:
// Matches:  ["GOODBYE","CRUEL","WORLD","IM","LEAVING","U","TODAY"]

let str = `GOODBYE,CRUEL,WORLD,IM,LEAVING,U,TODAY`
let matches = [];

function recurse(str, matches) {
    let regex = /^((,?([A-Z]+))+)$/gm
    let m
    while ((m = regex.exec(str)) !== null) {
        matches.unshift(m[3])
        return str.replace(m[2], '')
    }
    return "bzzt!"
}

while ((str = recurse(str, matches)) != "bzzt!") ;
console.log("Matches: ", JSON.stringify(matches))

Note: If you were really going to use this, you would use the position of the match as given by the regex match function, not a string replace.

This isn't really going to help with your more complex issue but I'm posting this anyway because it is a simple solution for people that aren't doing a global search like you are.

I've simplified the regex in the answer to be clearer (this is not a solution to your exact problem).

var re = /^(.+?):"(.+)"$/
var regExResult = re.exec('description:"aoeu"');
var purifiedResult = purify_regex(regExResult);

// We only want the group matches in the array
function purify_regex(reResult){

  // Removes the Regex specific values and clones the array to prevent mutation
  let purifiedArray = [...reResult];

  // Removes the full match value at position 0
  purifiedArray.shift();

  // Returns a pure array without mutating the original regex result
  return purifiedArray;
}

// purifiedResult= ["description", "aoeu"]

That looks more verbose than it is because of the comments, this is what it looks like without comments

var re = /^(.+?):"(.+)"$/
var regExResult = re.exec('description:"aoeu"');
var purifiedResult = purify_regex(regExResult);

function purify_regex(reResult){
  let purifiedArray = [...reResult];
  purifiedArray.shift();
  return purifiedArray;
}

Note that any groups that do not match will be listed in the array as undefined values.

This solution uses the ES6 spread operator to purify the array of regex specific values. You will need to run your code through Babel if you want IE11 support.

Add a third group by adding parens around .*, then replace the subsequence with "number" + m.group(2) + "1". e.g.:

String output = m.replaceFirst("number" + m.group(2) + "1");

Python Extension. From the Python Docs:

The solution chosen by the Perl developers was to use (?...) as the extension syntax. ? immediately after a parenthesis was a syntax error because the ? would have nothing to repeat, so this didn’t introduce any compatibility problems. The characters immediately after the ? indicate what extension is being used, so (?=foo) is one thing (a positive lookahead assertion) and (?:foo) is something else (a non-capturing group containing the subexpression foo).

Python supports several of Perl’s extensions and adds an extension syntax to Perl’s extension syntax.If the first character after the question mark is a P, you know that it’s an extension that’s specific to Python

Remember not all possible codes are used, so this list is a necessary but not sufficent condition for a valid code. It might be easier to just match against a list of all valid codes?

Here's how to look in the documentation.

First, you're dealing with IO, so look in the java.io package.

There are two classes that look interesting: FileFilter and FileNameFilter. When I clicked on the first, it showed me that there was a a listFiles() method in the File class. And the documentation for that method says:

Returns an array of abstract pathnames denoting the files in the directory denoted by this abstract pathname.

Scrolling up in the File JavaDoc, I see the constructors. And that's really all I need to be able to create a File instance and call listFiles() on it. Scrolling still further, I can see some information about how files are named in different operating systems.

I had a similar problem. Given a date, I wanted to get the date of the Monday of that week.

I used the following logic: Find the day number in the week in the range of 0-6, then subtract that from the originay date.

I used: DATEADD(day,-(DATEPART(weekday,)+5)%7,)

Since DATEPRRT(weekday,) returns 1 = Sundaye ... 7=Saturday, DATEPART(weekday,)+5)%7 returns 0=Monday ... 6=Sunday.

Subtracting this number of days from the original date gives the previous Monday. The same technique could be used for any starting day of the week.

If l is your list and X is your value:

for i in range(len(l) + 1):
    print l[:i] + [X] + l[i:]

To be able to give you specific help, you's have to explain what particular parts specifically "get messed up", or perhaps offer a screenshot. It also helps to know what version of Outlook you encounter the problem in.

Either way, CampaignMonitor.com's CSS guide has often helped me out debugging email client inconsistencies.

From that guide you can see several things just won't work well or at all in Outlook, here are some highlights of the more important ones:

• Various types of more sophisticated selectors, e.g. E:first-child, E:hover, E > F (Child combinator), E + F (Adjacent sibling combinator), E ~ F (General sibling combinator). This unfortunately means resorting to workarounds like inline styles.
• Some font properties, e.g. white-space won't work.
• The background-image property won't work.
• There are several issues with the Box Model properties, most importantly height, width, and the max- versions are either not usable or have bugs for certain elements.
• Positioning and Display issues (e.g. display, floats and position are all out).

In short: combining CSS and Outlook can be a pain. Be prepared to use many ugly workarounds.

PS. In your specific case, there are two minor issues in your html that may cause you odd behavior. There's "align=top" where you probably meant to use vertical-align. Also: cell-padding for tds doesn't exist.

There is a new feature in Directory and DirectoryInfo in .NET 4 that allows them to return an IEnumerable instead of an array, and start returning results before reading all the directory contents.

• What's New in the BCL in .NET 4 Beta 1
• Directory.EnumerateFileSystemEntries method overloads

public bool IsDirectoryEmpty(string path)
{
    IEnumerable<string> items = Directory.EnumerateFileSystemEntries(path);
    using (IEnumerator<string> en = items.GetEnumerator())
    {
        return !en.MoveNext();
    }
}

EDIT: seeing that answer again, I realize this code can be made much simpler...

public bool IsDirectoryEmpty(string path)
{
    return !Directory.EnumerateFileSystemEntries(path).Any();
}

Based on the above suggestions, the following data.table solution worked very fast for me:

library(data.table)

set.seed(45)
DT <- data.table(matrix(sample(10, 10^7, TRUE), ncol=10))

system.time(
  DT[, col_max := colnames(.SD)[max.col(.SD, ties.method = "first")]]
)
#>    user  system elapsed 
#>    0.15    0.06    0.21
DT[]
#>          V1 V2 V3 V4 V5 V6 V7 V8 V9 V10 col_max
#>       1:  7  4  1  2  3  7  6  6  6   1      V1
#>       2:  4  6  9 10  6  2  7  7  1   3      V4
#>       3:  3  4  9  8  9  9  8  8  6   7      V3
#>       4:  4  8  8  9  7  5  9  2  7   1      V4
#>       5:  4  3  9 10  2  7  9  6  6   9      V4
#>      ---                                       
#>  999996:  4  6 10  5  4  7  3  8  2   8      V3
#>  999997:  8  7  6  6  3 10  2  3 10   1      V6
#>  999998:  2  3  2  7  4  7  5  2  7   3      V4
#>  999999:  8 10  3  2  3  4  5  1  1   4      V2
#> 1000000: 10  4  2  6  6  2  8  4  7   4      V1

And also comes with the advantage that can always specify what columns .SD should consider by mentioning them in .SDcols:

DT[, MAX2 := colnames(.SD)[max.col(.SD, ties.method="first")], .SDcols = c("V9", "V10")]

In case we need the column name of the smallest value, as suggested by @lwshang, one just needs to use -.SD:

DT[, col_min := colnames(.SD)[max.col(-.SD, ties.method = "first")]]

You can create an extension for UIView to access these values in the design editor

extension UIView{

    @IBInspectable var shadowOffset: CGSize{
        get{
            return self.layer.shadowOffset
        }
        set{
            self.layer.shadowOffset = newValue
        }
    }

    @IBInspectable var shadowColor: UIColor{
        get{
            return UIColor(cgColor: self.layer.shadowColor!)
        }
        set{
            self.layer.shadowColor = newValue.cgColor
        }
    }

    @IBInspectable var shadowRadius: CGFloat{
        get{
            return self.layer.shadowRadius
        }
        set{
            self.layer.shadowRadius = newValue
        }
    }

    @IBInspectable var shadowOpacity: Float{
        get{
            return self.layer.shadowOpacity
        }
        set{
            self.layer.shadowOpacity = newValue
        }
    }
}

To create Anaconda Prompt using Command Prompt, just create a shortcut file of Command Prompt and modify the shortcut target to:

%windir%\System32\cmd.exe "/K" <Anaconda Location>\anaconda3\Scripts\activate.bat

Example:

%windir%\system32\cmd.exe "/K" C:\Users\user_1\AppData\Local\Continuum\anaconda3\Scripts\activate.bat

Used the answer above, but altered it for my needs.

I used the following function and imported to my REACT file where I needed to download the csv file.

I had a span tag within my th elements. Added comments to what most functions/methods do.

import { tableToCSV, downloadCSV } from './../Helpers/exportToCSV';


export function tableToCSV(){
  let tableHeaders = Array.from(document.querySelectorAll('th'))
    .map(item => {
      // title = splits elem tags on '\n',
      // then filter out blank "" that appears in array.
      // ex ["Timestamp", "[Full time]", ""]
      let title = item.innerText.split("\n").filter(str => (str !== 0)).join(" ")
      return title
    }).join(",")

  const rows = Array.from(document.querySelectorAll('tr'))
  .reduce((arr, currRow) => {
    // if tr tag contains th tag.
    // if null return array.
    if (currRow.querySelector('th')) return arr

    // concats individual cells into csv format row.
    const cells = Array.from(currRow.querySelectorAll('td'))
      .map(item => item.innerText)
      .join(',')
    return arr.concat([cells])
  }, [])

return tableHeaders + '\n' + rows.join('\n')
}

export function downloadCSV(csv){
  const csvFile = new Blob([csv], { type: 'text/csv' })
  const downloadLink =  document.createElement('a')
  // sets the name for the download file
  downloadLink.download = `CSV-${currentDateUSWritten()}.csv`
  // sets the url to the window URL created from csv file above
  downloadLink.href = window.URL.createObjectURL(csvFile)
  // creates link, but does not display it.
  downloadLink.style.display = 'none'
  // add link to body so click function below works
  document.body.appendChild(downloadLink)

  downloadLink.click()
}

When user click export to csv it trigger the following function in react.

  handleExport = (e) => {
    e.preventDefault();
    const csv = tableToCSV()
    return downloadCSV(csv)
  }

Example html table elems.

  <table id="datatable">
        <tbody>
          <tr id="tableHeader" className="t-header">
            <th>Timestamp
              <span className="block">full time</span></th>
            <th>current rate
              <span className="block">alt view</span>
            </th>
            <th>Battery Voltage
              <span className="block">current voltage

I created jquery.backgroundSize.js: a 1.5K jquery plugin that can be used as a IE8 fallback for "cover" and "contain" values. Have a look at the demo.

git log -n1 --format="Last committed item in this release was by %an, `git log -n1 --format=%at | awk '{print strftime("%y%m%d%H%M",$1)}'`, message: %s (%h) [%d]"

Another solution that wasn't mentioned:

Example Here

var parent = document.querySelector('.parent');

if (parent.querySelector('.child') !== null) {
    // .. it's a child
}

It doesn't matter whether the element is a direct child, it will work at any depth.

Alternatively, using the .contains() method:

Example Here

var parent = document.querySelector('.parent'),
    child = document.querySelector('.child');

if (parent.contains(child)) {
    // .. it's a child
}

After reporting the problem on the Android Studio feedback site, they found a solution for me. I am now using Gradle 1.10 and Android Studio 0.4.3.

Here is the link to the page with a description of how I fixed mine: https://code.google.com/p/android/issues/detail?id=65219

Hope this helps!

You could use the following code, it does a recursive call into the function in order to properly wait for the desired time.

function exportar(page,miliseconds,totalpages)
{
    if (page <= totalpages)
    {
        nextpage = page + 1;
        console.log('fnExcelReport('+ page +'); nextpage = '+ nextpage + '; miliseconds = '+ miliseconds + '; totalpages = '+ totalpages );
        fnExcelReport(page);
        setTimeout(function(){
            exportar(nextpage,miliseconds,totalpages);
        },miliseconds);
    };
}

Quickest and easiest way is to use the 'at' command:

ssh user@target "at now -f /home/foo.sh"

We are already in 21st century!! Don't try to implement the already existing data structures. Try to use the existing data structures.

Use STL or Boost library

Lots of hate for the Convert class here... Just to balance a little bit, there is one advantage for Convert - if you are handed an object,

Convert.ToDouble(o);

can just return the value easily if o is already a Double (or an int or anything readily castable).

Using Double.Parse or Double.TryParse is great if you already have it in a string, but

Double.Parse(o.ToString());

has to go make the string to be parsed first and depending on your input that could be more expensive.

Direct Javascript calls between frames and/or windows are only allowed if they conform to the same-origin policy. If your window and iframe share a common parent domain you can set document.domain to "domain lower") one or both such that they can communicate. Otherwise you'll need to look into something like the postMessage() API.

for Play 2.5.x and Play 2.6.x

follow some steps below:

1. open cygwin setup again

2. choose catagory on view tab

3. fill "make" in search tab

4. expand devel

5. find "make: a GNU version of the 'make' ultility", click to install

6. Done!

There are multiple answers to this question, partly due to ambiguous question - the title is talking about classes loaded by the JVM, whereas the contents of the question says "may or may not be loaded by the JVM".

Assuming that OP needs classes that are loaded by the JVM by a given classloader, and only those classes - my need as well - there is a solution (elaborated here) that goes like this:

import java.net.URL;
import java.util.Enumeration;
import java.util.Iterator;
import java.util.Vector;

public class CPTest {

    private static Iterator list(ClassLoader CL)
        throws NoSuchFieldException, SecurityException,
        IllegalArgumentException, IllegalAccessException {
        Class CL_class = CL.getClass();
        while (CL_class != java.lang.ClassLoader.class) {
            CL_class = CL_class.getSuperclass();
        }
        java.lang.reflect.Field ClassLoader_classes_field = CL_class
                .getDeclaredField("classes");
        ClassLoader_classes_field.setAccessible(true);
        Vector classes = (Vector) ClassLoader_classes_field.get(CL);
        return classes.iterator();
    }

    public static void main(String args[]) throws Exception {
        ClassLoader myCL = Thread.currentThread().getContextClassLoader();
        while (myCL != null) {
            System.out.println("ClassLoader: " + myCL);
            for (Iterator iter = list(myCL); iter.hasNext();) {
                System.out.println("\t" + iter.next());
            }
            myCL = myCL.getParent();
        }
    }

}

One of the neat things about it is that you can choose an arbitrary classloader you want to check. It is however likely to break should internals of classloader class change, so it is to be used as one-off diagnostic tool.

Using bash regular expressions:

re="http://([^/]+)/"
if [[ $name =~ $re ]]; then echo ${BASH_REMATCH[1]}; fi

Edit - OP asked for explanation of syntax. Regular expression syntax is a large topic which I can't explain in full here, but I will attempt to explain enough to understand the example.

re="http://([^/]+)/"

This is the regular expression stored in a bash variable, re - i.e. what you want your input string to match, and hopefully extract a substring. Breaking it down:

• http:// is just a string - the input string must contain this substring for the regular expression to match
• [] Normally square brackets are used say "match any character within the brackets". So c[ao]t would match both "cat" and "cot". The ^ character within the [] modifies this to say "match any character except those within the square brackets. So in this case [^/] will match any character apart from "/".
• The square bracket expression will only match one character. Adding a + to the end of it says "match 1 or more of the preceding sub-expression". So [^/]+ matches 1 or more of the set of all characters, excluding "/".
• Putting () parentheses around a subexpression says that you want to save whatever matched that subexpression for later processing. If the language you are using supports this, it will provide some mechanism to retrieve these submatches. For bash, it is the BASH_REMATCH array.
• Finally we do an exact match on "/" to make sure we match all the way to end of the fully qualified domain name and the following "/"

Next, we have to test the input string against the regular expression to see if it matches. We can use a bash conditional to do that:

if [[ $name =~ $re ]]; then
    echo ${BASH_REMATCH[1]}
fi

In bash, the [[ ]] specify an extended conditional test, and may contain the =~ bash regular expression operator. In this case we test whether the input string $name matches the regular expression $re. If it does match, then due to the construction of the regular expression, we are guaranteed that we will have a submatch (from the parentheses ()), and we can access it using the BASH_REMATCH array:

• Element 0 of this array ${BASH_REMATCH[0]} will be the entire string matched by the regular expression, i.e. "http://www.google.com/".
• Subsequent elements of this array will be subsequent results of submatches. Note you can have multiple submatch () within a regular expression - The BASH_REMATCH elements will correspond to these in order. So in this case ${BASH_REMATCH[1]} will contain "www.google.com", which I think is the string you want.

Note that the contents of the BASH_REMATCH array only apply to the last time the regular expression =~ operator was used. So if you go on to do more regular expression matches, you must save the contents you need from this array each time.

This may seem like a lengthy description, but I have really glossed over several of the intricacies of regular expressions. They can be quite powerful, and I believe with decent performance, but the regular expression syntax is complex. Also regular expression implementations vary, so different languages will support different features and may have subtle differences in syntax. In particular escaping of characters within a regular expression can be a thorny issue, especially when those characters would have an otherwise different meaning in the given language.

Note that instead of setting the $re variable on a separate line and referring to this variable in the condition, you can put the regular expression directly into the condition. However in bash 3.2, the rules were changed regarding whether quotes around such literal regular expressions are required or not. Putting the regular expression in a separate variable is a straightforward way around this, so that the condition works as expected in all bash versions that support the =~ match operator.

You simply need to make cab a string:

cab = '6176'

As the error message states, you cannot do <int> in <string>:

>>> 1 in '123'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'in <string>' requires string as left operand, not int
>>> 

because integers and strings are two totally different things and Python does not embrace implicit type conversion ("Explicit is better than implicit.").

In fact, Python only allows you to use the in operator with a right operand of type string if the left operand is also of type string:

>>> '1' in '123'  # Works!
True
>>>
>>> [] in '123'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'in <string>' requires string as left operand, not list
>>>
>>> 1.0 in '123'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'in <string>' requires string as left operand, not float
>>>
>>> {} in '123'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'in <string>' requires string as left operand, not dict

Before it was running on :docker run -d --name oracle -p 1521:1521 -p 5500:5500 qa/oracle I just changed the port to docker run -d --name oracle -p 1522:1522 -p 5500:5500 qa/oracle

it worked fine for me !

I've my answer in form of a conversation to be a better read:

Why do we need virtual functions?

Because of Polymorphism.

What is Polymorphism?

The fact that a base pointer can also point to derived type objects.

How does this definition of Polymorphism lead into the need for virtual functions?

Well, through early binding.

What is early binding?

Early binding(compile-time binding) in C++ means that a function call is fixed before the program is executed.

So...?

So if you use a base type as the parameter of a function, the compiler will only recognize the base interface, and if you call that function with any arguments from derived classes, it gets sliced off, which is not what you want to happen.

If it's not what we want to happen, why is this allowed?

Because we need Polymorphism!

What's the benefit of Polymorphism then?

You can use a base type pointer as the parameter of a single function, and then in the run-time of your program, you can access each of the derived type interfaces(e.g. their member functions) without any issues, using dereferencing of that single base pointer.

I still don't know what virtual functions are good for...! And this was my first question!

well, this is because you asked your question too soon!

Why do we need virtual functions?

Assume that you called a function with a base pointer, which had the address of an object from one of its derived classes. As we've talked about it above, in the run-time, this pointer gets dereferenced, so far so good, however, we expect a method(== a member function) "from our derived class" to be executed! However, a same method(one that has a same header) is already defined in the base class, so why should your program bother to choose the other method? In other words I mean, how can you tell this scenario off from what we used to see normally happen before?

The brief answer is "a Virtual member function in base", and a little longer answer is that, "at this step, if the program sees a virtual function in the base class, it knows(realizes) that you're trying to use polymorphism" and so goes to derived classes(using v-table, a form of late binding) to find that another method with the same header, but with -expectedly- a different implementation.

Why a different implementation?

You knuckle-head! Go read a good book!

OK, wait wait wait, why would one bother to use base pointers, when he/she could simply use derived type pointers? You be the judge, is all this headache worth it? Look at these two snippets:

//1:

Parent* p1 = &boy;
p1 -> task();
Parent* p2 = &girl;
p2 -> task();

//2:

Boy* p1 = &boy;
p1 -> task();
Girl* p2 = &girl;
p2 -> task();

OK, although I think that 1 is still better than 2, you could write 1 like this either:

//1:

Parent* p1 = &boy;
p1 -> task();
p1 = &girl;
p1 -> task();

and moreover, you should be aware that this is yet just a contrived use of all the things I've explained to you so far. Instead of this, assume for example a situation in which you had a function in your program that used the methods from each of the derived classes respectively(getMonthBenefit()):

double totalMonthBenefit = 0;    
std::vector<CentralShop*> mainShop = { &shop1, &shop2, &shop3, &shop4, &shop5, &shop6};
for(CentralShop* x : mainShop){
     totalMonthBenefit += x -> getMonthBenefit();
}

Now, try to re-write this, without any headaches!

double totalMonthBenefit=0;
Shop1* branch1 = &shop1;
Shop2* branch2 = &shop2;
Shop3* branch3 = &shop3;
Shop4* branch4 = &shop4;
Shop5* branch5 = &shop5;
Shop6* branch6 = &shop6;
totalMonthBenefit += branch1 -> getMonthBenefit();
totalMonthBenefit += branch2 -> getMonthBenefit();
totalMonthBenefit += branch3 -> getMonthBenefit();
totalMonthBenefit += branch4 -> getMonthBenefit();
totalMonthBenefit += branch5 -> getMonthBenefit();
totalMonthBenefit += branch6 -> getMonthBenefit();

And actually, this might be yet a contrived example either!

Building on the answers above using the indeterminate state, I've come up with a little bit that handles individual checkboxes and makes them tri-state.

MVC razor uses 2 inputs per checkbox anyway (the checkbox and a hidden with the same name to always force a value in the submit). MVC uses things like "true" as the checkbox value and "false" as the hidden of the same name; makes it amenable to boolean use in api calls. This snippet uses an third hidden to persist the last request values across submits.

Checkboxes initialized with the below will start indeterminate. Checking once turns on the checkbox. Checking twice turns off the checkbox (returning the hidden value of the same name). Checking a third time returns it to indeterminate (and clears out the hidden so a submit will produce a blank).

The page also populates another hidden (e.g. triBox2Orig) with whatever value was on the query string to start, so the 3 states can be initialized and persisted between submits.

$(document).ready(function () {
    var initCheckbox = function (chkBox)
    {
        var hidden = $('[name="' + $(chkBox).prop("name") + '"][type="hidden"]');
        var hiddenOrig = $('[name="' + $(chkBox).prop("name") + 'Orig"][type="hidden"]').prop("value");
        hidden.prop("origValue", hidden.prop("value"));
        if (!chkBox.prop("checked") && !hiddenOrig) chkBox.prop("indeterminate", true);
        if (chkBox.prop("indeterminate")) hidden.prop("value", null);
        chkBox.change(checkBoxToggleFun);
    }

    var checkBoxToggleFun = function ()
    {
        var isChecked = $(this).prop('checked');
        var hidden = $('[name="' + $(this).prop("name") + '"][type="hidden"]');
        var thirdState = isChecked && hidden.prop("value") === hidden.prop("origValue");
        if (thirdState) {   // on 3rd click of a checkbox, set it back to indeterminate
            $(this).prop("indeterminate", true);
            $(this).prop('checked', false);
        }
        hidden.prop("value", thirdState ? null : hidden.prop("origValue"));
    };

    var chkBox = $('#triBox1');
    initCheckbox(chkBox);

    chkBox = $('#triBox2');
    initCheckbox(chkBox);
});

try this command in terminal:

sudo ufw enable
ufw allow 12397

I used:

rm -r folderToDelete

This works for me like a charm (I stole it from Ubuntu).

The only way not to capture something is using look-around assertions:

(?<=123-)((apple|banana)(?=-456)|(?=456))

Because even with non-capturing groups (?:…) the whole regular expression captures their matched contents. But this regular expression matches only apple or banana if it’s preceded by 123- and followed by -456, or it matches the empty string if it’s preceded by 123- and followed by 456.

|Lookaround  |    Name      |        What it Does                       |
-----------------------------------------------------------------------
|(?=foo)     |   Lookahead  | Asserts that what immediately FOLLOWS the |
|            |              |  current position in the string is foo    |
-------------------------------------------------------------------------
|(?<=foo)    |   Lookbehind | Asserts that what immediately PRECEDES the|
|            |              |  current position in the string is foo    |
-------------------------------------------------------------------------
|(?!foo)     |   Negative   | Asserts that what immediately FOLLOWS the |
|            |   Lookahead  |  current position in the string is NOT foo|
-------------------------------------------------------------------------
|(?<!foo)    |   Negative   | Asserts that what immediately PRECEDES the|
|            |   Lookbehind |  current position in the string is NOT foo|

You are using DictWriter.writerows() which expects a list of dicts, not a dict. You want DictWriter.writerow() to write a single row.

You will also want to use DictWriter.writeheader() if you want a header for you csv file.

You also might want to check out the with statement for opening files. It's not only more pythonic and readable but handles closing for you, even when exceptions occur.

Example with these changes made:

import csv

my_dict = {"test": 1, "testing": 2}

with open('mycsvfile.csv', 'w') as f:  # You will need 'wb' mode in Python 2.x
    w = csv.DictWriter(f, my_dict.keys())
    w.writeheader()
    w.writerow(my_dict)

Which produces:

test,testing
1,2

Create table and have required columns that are used for creating table in csv file.

1. Open postgres and right click on target table which you want to load & select import and Update the following steps in file options section

2. Now browse your file in filename

3. Select csv in format

4. Encoding as ISO_8859_5

Now goto Misc. options and check header and click on import.

You could use the substr function please check following example,

$string1 = "tarunmodi";
$first4 = substr($string1, 4);
echo $first4;

Output: nmodi

while installing python packages in a global environment is doable, it is a best practice to isolate the environment between projects (creating virtual environments). Otherwise, confusion between Python versions will arise, just like your problem.

The simplest method is to use venv library in the project directory:

python3 -m venv venv

Where the first venv is to call the venv package, and the second venv defines the virtual environment directory name. Then activate the virtual environment:

source venv/bin/activate

Once the virtual environment has been activated, your pip install ... commands would not be interfered with any other Python version or pip version anymore. For installing requests:

pip install requests

Another benefit of the virtual environment is to have a concise list of libraries needed for that specific project.

*note: commands only work on Linux and Mac OS

It's not generally correct that you can "remove an item from a database" with both methods. To be precise it is like so:

• ObjectContext.DeleteObject(entity) marks the entity as Deleted in the context. (It's EntityState is Deleted after that.) If you call SaveChanges afterwards EF sends a SQL DELETE statement to the database. If no referential constraints in the database are violated the entity will be deleted, otherwise an exception is thrown.

• EntityCollection.Remove(childEntity) marks the relationship between parent and childEntity as Deleted. If the childEntity itself is deleted from the database and what exactly happens when you call SaveChanges depends on the kind of relationship between the two:

  • If the relationship is optional, i.e. the foreign key that refers from the child to the parent in the database allows NULL values, this foreign will be set to null and if you call SaveChanges this NULL value for the childEntity will be written to the database (i.e. the relationship between the two is removed). This happens with a SQL UPDATE statement. No DELETE statement occurs.

  • If the relationship is required (the FK doesn't allow NULL values) and the relationship is not identifying (which means that the foreign key is not part of the child's (composite) primary key) you have to either add the child to another parent or you have to explicitly delete the child (with DeleteObject then). If you don't do any of these a referential constraint is violated and EF will throw an exception when you call SaveChanges - the infamous "The relationship could not be changed because one or more of the foreign-key properties is non-nullable" exception or similar.

  • If the relationship is identifying (it's necessarily required then because any part of the primary key cannot be NULL) EF will mark the childEntity as Deleted as well. If you call SaveChanges a SQL DELETE statement will be sent to the database. If no other referential constraints in the database are violated the entity will be deleted, otherwise an exception is thrown.

I am actually a bit confused about the Remarks section on the MSDN page you have linked because it says: "If the relationship has a referential integrity constraint, calling the Remove method on a dependent object marks both the relationship and the dependent object for deletion.". This seems unprecise or even wrong to me because all three cases above have a "referential integrity constraint" but only in the last case the child is in fact deleted. (Unless they mean with "dependent object" an object that participates in an identifying relationship which would be an unusual terminology though.)

Use pure bit logic:

DECLARE @Product TABLE (
    id INT PRIMARY KEY IDENTITY NOT NULL
   ,Obsolote CHAR(1)
   ,Instock CHAR(1)
)

INSERT INTO @Product ([Obsolote], [Instock])
    VALUES ('N', 'N'), ('N', 'Y'), ('Y', 'Y'), ('Y', 'N')

;
WITH cte
AS
(
    SELECT
        'CheckIfInstock' = CAST(ISNULL(NULLIF(ISNULL(NULLIF(p.[Instock], 'Y'), 1), 'N'), 0) AS BIT)
       ,'CheckIfObsolote' = CAST(ISNULL(NULLIF(ISNULL(NULLIF(p.[Obsolote], 'N'), 0), 'Y'), 1) AS BIT)
       ,*
    FROM
        @Product AS p
)
SELECT
    'Salable' = c.[CheckIfInstock] & ~c.[CheckIfObsolote]
   ,*
FROM
    [cte] c

See working demo: if then without case in SQL Server.

For start, you need to work out the value of true and false for selected conditions. Here comes two NULLIF:

for true: ISNULL(NULLIF(p.[Instock], 'Y'), 1)
for false: ISNULL(NULLIF(p.[Instock], 'N'), 0)

combined together gives 1 or 0. Next use bitwise operators.

It's the most WYSIWYG method.

The way I do a different styled button that works quite well is to subclass the Button object and apply a colour filter. This also handles enabled and disabled states by applying an alpha to the button.

import android.annotation.TargetApi;

        super(context);
    }

    public DimmableButton(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public DimmableButton(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    @SuppressWarnings("deprecation")
    @Override
    public void setBackgroundDrawable(Drawable d) {
        // Replace the original background drawable (e.g. image) with a LayerDrawable that
        // contains the original drawable.
        DimmableButtonBackgroundDrawable layer = new DimmableButtonBackgroundDrawable(d);
        super.setBackgroundDrawable(layer);
    }

    @TargetApi(Build.VERSION_CODES.JELLY_BEAN)
    @Override

        // contains the original drawable.
        DimmableButtonBackgroundDrawable layer = new DimmableButtonBackgroundDrawable(d);
        super.setBackground(layer);
    }

    /**

    protected class DimmableButtonBackgroundDrawable extends LayerDrawable {

        // The color filter to apply when the button is pressed
        protected ColorFilter _pressedFilter = new LightingColorFilter(Color.LTGRAY, 1);
        // Alpha value when the button is disabled
        protected int _disabledAlpha = 100;
        // Alpha value when the button is enabled
        protected int _fullAlpha = 255;

        public DimmableButtonBackgroundDrawable(Drawable d) {
            super(new Drawable[] { d });
        }

        @Override
        protected boolean onStateChange(int[] states) {
            boolean enabled = false;
            boolean pressed = false;

            for (int state : states) {
                if (state == android.R.attr.state_enabled)
                    enabled = true;
                else if (state == android.R.attr.state_pressed)
                    pressed = true;
            }

            mutate();
            if (enabled && pressed) {
                setColorFilter(_pressedFilter);
            } else if (!enabled) {
                setColorFilter(null);
                setAlpha(_disabledAlpha);
            } else {
                setColorFilter(null);
                setAlpha(_fullAlpha);
            }

            invalidateSelf();

            return super.onStateChange(states);
        }

        @Override
        public boolean isStateful() {
            return true;
        }
    }

}

I use this solution to delete empty lines and join everything together as one line:

match_p = re.sub(r'\s{2}', '', my_txt) # my_txt is text above

vars(obj) returns the attributes of an object.

First of all, thank you all for your inputs. I tweak my Query - 1 and got my desired result. Gordon Linoff is right, PRINT was messing up my query so I modified it as following:

Modified Query - 1:

SET ROWCOUNT 5
WHILE (1 = 1)
  BEGIN
    BEGIN TRANSACTION

        UPDATE TableName 
        SET Value = 'abc1' 
        WHERE Parameter1 = 'abc' AND Parameter2 = 123

        IF @@ROWCOUNT = 0
          BEGIN
                COMMIT TRANSACTION
                BREAK
          END
    COMMIT TRANSACTION
  END
SET ROWCOUNT  0

Output:

(5 row(s) affected)

(5 row(s) affected)

(4 row(s) affected)

(0 row(s) affected)

Going forward, for graphical elements that are purely decorative, the best solution is to use:

android:importantForAccessibility="no"

This makes sense if your min SDK version is at least 16, since devices running lower versions will ignore this attribute.

If you're stuck supporting older versions, you should use (like others pointed out already):

android:contentDescription="@null"

I had the same problem so i decided to start writing a small tool to help me with this. Im gonna share andopen source it.

https://github.com/BrunoAlexandreMendesMartins/CleverModels

It supports, JAVA, C# & Objective-c from JSON .

Feel free to contribute!

I think that what you are stating as the "difference" is actually a consequence of the real difference.

The actual difference is the target of the code written. Who is going to run this code.

A scripting language is used to write code that is going to target a software system. It's going to automate operations on that software system. The script is going to be a sequence of instructions to the target software system.

A programming language targets the computing system, which can be a real or virtual machine. The instructions are executed by the machine.

Of course, a real machine understands only binary code so you need to compile the code of a programming language. But this is a consequence of targeting a machine instead of a program.

In the other hand, the target software system of an script may compile the code or interpret it. Is up to the software system.

If we say that the real difference is whether it is compiled or not, then we have a problem because when Javascript runs in V8 is compiled and when it runs in Rhino is not.

It gets more confusing since scripting languages have evolved to become very powerful. So they are not limited to create small scripts to automate operations on another software system, you can create any rich applications with them.

Python code targets an interpreter so we can say that it "scripts" operations on that interpreter. But when you write Python code you don't see it as scripting an interpreter, you see it as creating an application. The interpreter is just there to code at a higher level among other things. So for me Python is more a programming language than an scripting language.

Another option, if you're happy to have this feature only for newer browsers, is to use the support offered by HTML 5's placeholder attribute:

<input name="email" placeholder="Email Address">

In the absence of any styles, in Chrome this looks like:

You can try demos out here and in HTML5 Placeholder Styling with CSS.

Be sure to check the browser compatibility of this feature. Support in Firefox was added in 3.7. Chrome is fine. Internet Explorer only added support in 10. If you target a browser that does not support input placeholders, you can use a jQuery plugin called jQuery HTML5 Placeholder, and then just add the following JavaScript code to enable it.

$('input[placeholder], textarea[placeholder]').placeholder();

check http://www.tech-archive.net/Archive/VB/microsoft.public.vb.database.ado/2005-08/msg00056.html

one needs to use something like

cmd.CommandText = "BEGIN foo@v; END;" 

worked for me in vb.net, c#

Otherwise... if

getenforce

returns

Enforcing

Then maybe you should call

setenforce 0 
mount -o rw,remount /system 
setenforce 1

import { Router, NavigationEnd } from "@angular/router";

constructor(private router: Router) {
  // Detect current route
  router.events.subscribe(val => {
    if (val instanceof NavigationEnd) {
      console.log(val.url);
    }
});

You can use

display: flex;

CSS property, as mentioned before by @Ayan, but I've created a working example: https://jsfiddle.net/d2kjxd51/

This happened to me when I upgraded. I had to downgrade back.

react-redux ^5.0.6 ? ^7.1.3

Another trick for getting sequential pieces (beyond the seq solution already mentioned) is to use a short logical vector and use vector recycling:

foo[ c( rep(FALSE, 5), TRUE ) ]

in asp.net:

color_black = (Color)new ColorConverter().ConvertFromString("#FF76B3");

At the moment, this can be done as follows

$ANDROID_HOME/build-tools/28.0.3/aapt dump badging /<path to>/<app name>.apk

In General, it will be:

$ANDROID_HOME/build-tools/<version_of_build_tools>/aapt dump badging /<path to>/<app name>.apk

I had the same problem, where the character index reported in the java error message was incorrect. I narrowed it down to the double quote characters just prior to the reported position being hex 094 (cancel instead of quote, but represented as a quote) instead of hex 022. As soon as I swapped for the hex 022 variant all was fine.

You can write your function to take a const std::string&:

void print(const std::string& input)
{
    cout << input << endl;
}

or a const char*:

void print(const char* input)
{
    cout << input << endl;
}

Both ways allow you to call it like this:

print("Hello World!\n"); // A temporary is made
std::string someString = //...
print(someString); // No temporary is made

The second version does require c_str() to be called for std::strings:

print("Hello World!\n"); // No temporary is made
std::string someString = //...
print(someString.c_str()); // No temporary is made

It was changed between 3.1 and 3.2:

This is a terse description of the new features added to bash-3.2 since the release of bash-3.1.

Quoting the string argument to the [[ command's =~ operator now forces string matching, as with the other pattern-matching operators.

So use it without the quotes thus:

i="test"
if [[ $i =~ 200[78] ]] ; then
    echo "OK"
else
    echo "not OK"
fi

You can use Thrift server or JMX to communicate with your Java service.

private SelectList AddFirstItem(SelectList list)
        {
            List<SelectListItem> _list = list.ToList();
            _list.Insert(0, new SelectListItem() { Value = "-1", Text = "This Is First Item" });
            return new SelectList((IEnumerable<SelectListItem>)_list, "Value", "Text");
        }

This Should do what you need ,just send your selectlist and it will return a select list with an item in index 0

You can custome the text,value or even the index of the item you need to insert

Since this is only an issue in IE, to resolve this, I'm first detecting if the browser is IE and if so, use a jquery click event. I put this code into a global file so it's fixed throughout the site.

if (navigator.appName === 'Microsoft Internet Explorer')
{
    $('a input.button').click(function()
    {
        window.location = $(this).closest('a').attr('href');
    });
}

This way we only have the overhead of assigning click events to linked input buttons for IE. note: The above code is inside a document ready function to make sure the page is completely loaded before assigning click events.

I also assigned class names to my input buttons to save some overhead when using IE so I can search for

$('a input.button')

instead of

$('a input[type=button]')

.

<a href="some_link"><input type="button" class="button" value="some value" /></a>

On top of all that, I'm also utilizing CSS to make the buttons look clickable when your mouse hovers over it:

input.button {cursor: pointer}

Honestly, the best and most simple template engine for Node.js is (IMHO) Plates (https://github.com/flatiron/plates). You might also want to check out the Flatiron MVC framework for Node.js (http://flatiron.org).

using padding pad

In order to move the colorbar relative to the subplot, one may use the pad argument to fig.colorbar.

import matplotlib.pyplot as plt
import numpy as np; np.random.seed(1)

fig, ax = plt.subplots(figsize=(4,4))
im = ax.imshow(np.random.rand(11,16))
ax.set_xlabel("x label")

fig.colorbar(im, orientation="horizontal", pad=0.2)
plt.show()

using an axes divider

One can use an instance of make_axes_locatable to divide the axes and create a new axes which is perfectly aligned to the image plot. Again, the pad argument would allow to set the space between the two axes.

import matplotlib.pyplot as plt
from mpl_toolkits.axes_grid1 import make_axes_locatable
import numpy as np; np.random.seed(1)

fig, ax = plt.subplots(figsize=(4,4))
im = ax.imshow(np.random.rand(11,16))
ax.set_xlabel("x label")

divider = make_axes_locatable(ax)
cax = divider.new_vertical(size="5%", pad=0.7, pack_start=True)
fig.add_axes(cax)
fig.colorbar(im, cax=cax, orientation="horizontal")

plt.show()

using subplots

One can directly create two rows of subplots, one for the image and one for the colorbar. Then, setting the height_ratios as gridspec_kw={"height_ratios":[1, 0.05]} in the figure creation, makes one of the subplots much smaller in height than the other and this small subplot can host the colorbar.

import matplotlib.pyplot as plt
import numpy as np; np.random.seed(1)

fig, (ax, cax) = plt.subplots(nrows=2,figsize=(4,4), 
                  gridspec_kw={"height_ratios":[1, 0.05]})
im = ax.imshow(np.random.rand(11,16))
ax.set_xlabel("x label")

fig.colorbar(im, cax=cax, orientation="horizontal")

plt.show()

This could help: http://finance.yahoo.com/d/quotes.csv?e=.csv&f=c4l1&s=EURUSD=X,GBPUSD=X It will return csv file:

no need to require the ckeditor.php, because CKEditor will not processed by PHP...

you need just following the _samples directory and see what they do.

just need to include ckeditor.js by html tag, and do some configuration in javascript.

This workaround is simpler and more elegant than explode:

$my_date = str_replace("/", ".", $my_date);
$my_date = strtotime($my_date);
$my_date = date("Y-m-d", $my_date);

You don't have to know what format you're getting the date in, but if it comes with slashes they are replaced with full stops and it is treated as European by strtotime.

Thread is old but I needed this kind of feature in my application and I found a way to do it so I decided to post it if it can help anyone in my situation.

As our device fleet is composed only by Samsung Galaxy Tab 2, I just had to find the file explorer's package name, give the right path and I succeed open my file explorer where I wanted to. I wish I could use Intent.CATEGORY_APP_FILES but it is only available in API 29.

  Intent intent = context.getPackageManager().getLaunchIntentForPackage("com.sec.android.app.myfiles");
  Uri uri = Uri.parse(rootPath);
  if (intent != null) {
      intent.setData(uri);
      startActivity(intent);

As I said, it was easy for me because our clients have the same device but it may help others to find a workaround for their own situation.

I have been searching for this for ages on my CM 11 android phone, running kitkat.

Well.. finally I found it. It's hidden in a totally unintuitive location:

1. Go to settings
2. Go to storage
3. Open the menu and choose USB computer connection

Here you can choose between Media Device (MTP), Camera (PTP) and Mass storage (UMS). Turn them all off to get it to charge only.

Sadly, if the option is not there, it is not supported by the phone. This seems to be the case for my HTC One (M7).

I'd recommend this article on CSS Tricks by Chris Coyier entitled Better Helvetica:

http://css-tricks.com/snippets/css/better-helvetica/

He basically recommends the following declaration for covering all the bases:

body {
    font-family: "HelveticaNeue-Light", "Helvetica Neue Light", "Helvetica Neue", Helvetica, Arial, "Lucida Grande", sans-serif; 
    font-weight: 300;
}

A hybrid approach combining charAt with your requirement of not getting char could be

newstring = String.valueOf("foo".charAt(0));

But that's not really "neater" than substring() to be honest.

Using this Log-Entry framework:

Script:

Function Main {
    Log -File "D:\Apps\Logs\$Env:computername.log"

    $tcp = (get-childitem c:\windows\system32\drivers\tcpip.sys).Versioninfo.ProductVersionRaw
    $dfs = (get-childitem C:\Windows\Microsoft.NET\Framework\v2.0.50727\dfsvc.exe).Versioninfo.ProductVersionRaw

    Log "TCPIP.sys Version on $computer is:" $tcp
    Log "DFSVC.exe Version on $computer is:" $dfs

    If (get-wmiobject win32_share | where-object {$_.Name -eq "REMINST"}) {Log "The REMINST share exists on $computer"}
    Else {Log "The REMINST share DOES NOT exist on $computer - Please create as per standards"}

    "KB2450944", "KB3150513", "KB3176935" | ForEach {
        $hotfix = Get-HotFix -Id $_ -ErrorAction SilentlyContinue
        If ($hotfix) {Log -Color Green Hotfix $_ is installed}
        Else {Log -Color Red Hotfix $_ " is NOT installed - Please ensure you install this hotfix"}
    }
}

Screen output:

Had that issue on Ubuntu 14.04, In my case I had also libXtst.so missing:

Could not open library 'libXtst.so': libXtst.so: cannot open shared object 
file: No such file or directory

Make sure your symbolic link is pointing to proper file, cd /usr/lib/x86_64-linux-gnu and list libXtst with:

 ll |grep libXtst                                                                                                                                                           
 lrwxrwxrwx   1 root root        16 Oct  7  2016 libXtst.so.6 -> libXtst.so.6.1.0
 -rw-r--r--   1 root root     22880 Aug 16  2013 libXtst.so.6.1.0

Then just create proper symbolic link using:

sudo ln -s libXtst.so.6 libXtst.so

List again:

ll | grep libXtst
lrwxrwxrwx   1 root root        12 Sep 20 10:23 libXtst -> libXtst.so.6
lrwxrwxrwx   1 root root        12 Sep 20 10:23 libXtst.so -> libXtst.so.6
lrwxrwxrwx   1 root root        16 Oct  7  2016 libXtst.so.6 -> libXtst.so.6.1.0
-rw-r--r--   1 root root     22880 Aug 16  2013 libXtst.so.6.1.0

all set!

The closest equivalent to your VB would be (see this):

Convert.IsDBNull()

But there are a number of ways to do this, and most are linked from here

To perform this operation see the next images:

and next step is add *.mdf file,

very important, the .mdf file must be located in C:......\MSSQL12.SQLEXPRESS\MSSQL\DATA

Now remove the log file

As Gregg Lind suggested, you can use reword to be prompted to only change the commit message (and leave the commit intact otherwise):

git rebase -i HEAD~n

Here, n is the list of last n commits.

For example, if you use git rebase -i HEAD~4, you may see something like this:

pick e459d80 Do xyz
pick 0459045 Do something
pick 90fdeab Do something else
pick facecaf Do abc

Now replace pick with reword for the commits you want to edit the messages of:

pick e459d80 Do xyz
reword 0459045 Do something
reword 90fdeab Do something else
pick facecaf Do abc

Exit the editor after saving the file, and next you will be prompted to edit the messages for the commits you had marked reword, in one file per message. Note that it would've been much simpler to just edit the commit messages when you replaced pick with reword, but doing that has no effect.

Learn more on GitHub's page for Changing a commit message.

//in aspx page

<asp:TextBox ID="password" runat="server" TextMode="Password" />

//in MVC cshtml

@Html.Password("password", "", new { id = "password", Textmode = "Password" })

andyras is completely correct. One minor addition, try this (for example)

plot 'ls.dat' using 4:xtic(1)

This will keep your datafile in the correct order, but also preserve your version tic labels on the x-axis.

(Background: I have some experience implementing C and C++ compilers.)

Variable-length arrays in C99 were basically a misstep. In order to support VLAs, C99 had to make the following concessions to common sense:

• sizeof x is no longer always a compile-time constant; the compiler must sometimes generate code to evaluate a sizeof-expression at runtime.

• Allowing two-dimensional VLAs (int A[x][y]) required a new syntax for declaring functions that take 2D VLAs as parameters: void foo(int n, int A[][*]).

• Less importantly in the C++ world, but extremely important for C's target audience of embedded-systems programmers, declaring a VLA means chomping an arbitrarily large chunk of your stack. This is a guaranteed stack-overflow and crash. (Anytime you declare int A[n], you're implicitly asserting that you have 2GB of stack to spare. After all, if you know "n is definitely less than 1000 here", then you would just declare int A[1000]. Substituting the 32-bit integer n for 1000 is an admission that you have no idea what the behavior of your program ought to be.)

Okay, so let's move to talking about C++ now. In C++, we have the same strong distinction between "type system" and "value system" that C89 does… but we've really started to rely on it in ways that C has not. For example:

template<typename T> struct S { ... };
int A[n];
S<decltype(A)> s;  // equivalently, S<int[n]> s;

If n weren't a compile-time constant (i.e., if A were of variably modified type), then what on earth would be the type of S? Would S's type also be determined only at runtime?

What about this:

template<typename T> bool myfunc(T& t1, T& t2) { ... };
int A1[n1], A2[n2];
myfunc(A1, A2);

The compiler must generate code for some instantiation of myfunc. What should that code look like? How can we statically generate that code, if we don't know the type of A1 at compile time?

Worse, what if it turns out at runtime that n1 != n2, so that !std::is_same<decltype(A1), decltype(A2)>()? In that case, the call to myfunc shouldn't even compile, because template type deduction should fail! How could we possibly emulate that behavior at runtime?

Basically, C++ is moving in the direction of pushing more and more decisions into compile-time: template code generation, constexpr function evaluation, and so on. Meanwhile, C99 was busy pushing traditionally compile-time decisions (e.g. sizeof) into the runtime. With this in mind, does it really even make sense to expend any effort trying to integrate C99-style VLAs into C++?

As every other answerer has already pointed out, C++ provides lots of heap-allocation mechanisms (std::unique_ptr<int[]> A = new int[n]; or std::vector<int> A(n); being the obvious ones) when you really want to convey the idea "I have no idea how much RAM I might need." And C++ provides a nifty exception-handling model for dealing with the inevitable situation that the amount of RAM you need is greater than the amount of RAM you have. But hopefully this answer gives you a good idea of why C99-style VLAs were not a good fit for C++ — and not really even a good fit for C99. ;)

For more on the topic, see N3810 "Alternatives for Array Extensions", Bjarne Stroustrup's October 2013 paper on VLAs. Bjarne's POV is very different from mine; N3810 focuses more on finding a good C++ish syntax for the things, and on discouraging the use of raw arrays in C++, whereas I focused more on the implications for metaprogramming and the typesystem. I don't know if he considers the metaprogramming/typesystem implications solved, solvable, or merely uninteresting.

A good blog post that hits many of these same points is "Legitimate Use of Variable Length Arrays" (Chris Wellons, 2019-10-27).

To add to Lennart Regebro's answer There is even the third way that can be used:

encoded3 = str.encode(original, 'utf-8')
print(encoded3)

Anyway, it is actually exactly the same as the first approach. It may also look that the second way is a syntactic sugar for the third approach.

A programming language is a means to express abstract ideas formally, to be executed by the machine. A programming language is considered good if it contains constructs that one needs. Python is a hybrid language -- i.e. more natural and more versatile than pure OO or pure procedural languages. Sometimes functions are more appropriate than the object methods, sometimes the reverse is true. It depends on mental picture of the solved problem.

Anyway, the feature mentioned in the question is probably a by-product of the language implementation/design. In my opinion, this is a nice example that show the alternative thinking about technically the same thing.

In other words, calling an object method means thinking in terms "let the object gives me the wanted result". Calling a function as the alternative means "let the outer code processes the passed argument and extracts the wanted value".

The first approach emphasizes the ability of the object to do the task on its own, the second approach emphasizes the ability of an separate algoritm to extract the data. Sometimes, the separate code may be that much special that it is not wise to add it as a general method to the class of the object.

<br>

Normally virtualenv creates environments in the current directory. Unless you're intending to create virtual environments in C:\Windows\system32 for some reason, I would use a different directory for environments.

You shouldn't need to mess with paths: use the activate script (in <env>\Scripts) to ensure that the Python executable and path are environment-specific. Once you've done this, the command prompt changes to indicate the environment. You can then just invoke easy_install and whatever you install this way will be installed into this environment. Use deactivate to set everything back to how it was before activation.

Example:

c:\Temp>virtualenv myenv
New python executable in myenv\Scripts\python.exe
Installing setuptools..................done.
c:\Temp>myenv\Scripts\activate
(myenv) C:\Temp>deactivate
C:\Temp>

Notice how I didn't need to specify a path for deactivate - activate does that for you, so that when activated "Python" will run the Python in the virtualenv, not your system Python. (Try it - do an import sys; sys.prefix and it should print the root of your environment.)

You can just activate a new environment to switch between environments/projects, but you'll need to specify the whole path for activate so it knows which environment to activate. You shouldn't ever need to mess with PATH or PYTHONPATH explicitly.

If you use Windows Powershell then you can take advantage of a wrapper. On Linux, the virtualenvwrapper (the link points to a port of this to Powershell) makes life with virtualenv even easier.

Update: Not incorrect, exactly, but perhaps not quite in the spirit of virtualenv. You could take a different tack: for example, if you install Django and anything else you need for your site in your virtualenv, then you could work in your project directory (where you're developing your site) with the virtualenv activated. Because it was activated, your Python would find Django and anything else you'd easy_installed into the virtual environment: and because you're working in your project directory, your project files would be visible to Python, too.

Further update: You should be able to use pip, distribute instead of setuptools, and just plain python setup.py install with virtualenv. Just ensure you've activated an environment before installing something into it.

You can use the below function to check if variant or string array is empty in vba

Function IsArrayAllocated(Arr As Variant) As Boolean
        On Error Resume Next
        IsArrayAllocated = IsArray(Arr) And _
                           Not IsError(LBound(Arr, 1)) And _
                           LBound(Arr, 1) <= UBound(Arr, 1)
End Function

Sample usage

Public Function test()
Dim Arr(1) As String
Arr(0) = "d"
Dim x As Boolean
x = IsArrayAllocated(Arr)
End Function

To use the hex encoding in Python 3, use

>>> import codecs
>>> codecs.encode(b"c", "hex")
b'63'

In legacy Python, there are several other ways of doing this:

>>> hex(ord("c"))
'0x63'
>>> format(ord("c"), "x")
'63'
>>> "c".encode("hex")
'63'

Short answer

git rev-list --max-parents=0 HEAD

_{(from tiho's comment. As Chris Johnsen notices, --max-parents was introduced after this answer was posted.)}

Explanation

Technically, there may be more than one root commit. This happens when multiple previously independent histories are merged together. It is common when a project is integrated via a subtree merge.

The git.git repository has six root commits in its history graph (one each for Linus’s initial commit, gitk, some initially separate tools, git-gui, gitweb, and git-p4). In this case, we know that e83c516 is the one we are probably interested in. It is both the earliest commit and a root commit.

It is not so simple in the general case.

Imagine that libfoo has been in development for a while and keeps its history in a Git repository (libfoo.git). Independently, the “bar” project has also been under development (in bar.git), but not for as long libfoo (the commit with the earliest date in libfoo.git has a date that precedes the commit with the earliest date in bar.git). At some point the developers of “bar” decide to incorporate libfoo into their project by using a subtree merge. Prior to this merge it might have been trivial to determine the “first” commit in bar.git (there was probably only one root commit). After the merge, however, there are multiple root commits and the earliest root commit actually comes from the history of libfoo, not “bar”.

You can find all the root commits of the history DAG like this:

git rev-list --max-parents=0 HEAD

For the record, if --max-parents weren't available, this does also work:

git rev-list --parents HEAD | egrep "^[a-f0-9]{40}$"

If you have useful tags in place, then git name-rev might give you a quick overview of the history:

git rev-list --parents HEAD | egrep "^[a-f0-9]{40}$" | git name-rev --stdin

Bonus

Use this often? Hard to remember? Add a git alias for quick access

git config --global alias.first "rev-list --max-parents=0 HEAD"

Now you can simply do

git first

dovers gives us his great answer and based on it you can try use it like

public static class CellDataFormat
{
        public static string General { get { return "General"; } }
        public static string Number { get { return "0"; } }

        // Your custom format 
        public static string NumberDotTwoDigits { get { return "0.00"; } }

        public static string Currency { get { return "$#,##0.00;[Red]$#,##0.00"; } }
        public static string Accounting { get { return "_($* #,##0.00_);_($* (#,##0.00);_($* \" - \"??_);_(@_)"; } }
        public static string Date { get { return "m/d/yy"; } }
        public static string Time { get { return "[$-F400] h:mm:ss am/pm"; } }
        public static string Percentage { get { return "0.00%"; } }
        public static string Fraction { get { return "# ?/?"; } }
        public static string Scientific { get { return "0.00E+00"; } }
        public static string Text { get { return "@"; } }
        public static string Special { get { return ";;"; } }
        public static string Custom { get { return "#,##0_);[Red](#,##0)"; } }
}

this is what it worked for me I'm using html2pdf from an Angular2 app, so I made a reference to this function in the controller

var html2pdf = (function(html2canvas, jsPDF) {

declared in html2pdf.js.

So I added just after the import declarations in my angular-controller this declaration:

declare function html2pdf(html2canvas, jsPDF): any;

then, from a method of my angular controller I'm calling this function:

generate_pdf(){
    this.someService.loadContent().subscribe(
      pdfContent => {
        html2pdf(pdfContent, {
          margin:       1,
          filename:     'myfile.pdf',
          image:        { type: 'jpeg', quality: 0.98 },
          html2canvas:  { dpi: 192, letterRendering: true },
          jsPDF:        { unit: 'in', format: 'A4', orientation: 'portrait' }
        });
      }
    );
  }

Hope it helps

The error message which you specified is nothing but you are not specifying goal for maven build.

you can specify any goal in your run configuration for maven build like clear, compile, install, package.

please following below step to resolve it.

1. right click on your project.
2. click 'Run as' and select 'Maven Build'
3. edit Configuration window will open. write any goal but your problem specific write 'package' in Goal text box.
4. click on 'Run'

This worked for me

<div style="display: flex; position: absolute; width: 100%;">
  <div style="white-space: nowrap; overflow: hidden;text-overflow: ellipsis;">
    Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer nec odio. Praesent libero. Sed cursus ante dapibus diam. Sed nisi.
  </div>
</div>

Adding position:absolute to the parent container made it work.

PS: This is for anyone looking for a solution to dynamically truncating text.

EDIT: This was meant to be an answer for this question but since they are related and it could help someone on this question I shall also leave it here instead of deleting it.

in fact the Is is really good, since to the developpers, you may want to override the operator ==, to compare with the value. say you have a class A, operator == of A is to compare some of the field of A to the parameter. then you will be in trouble in c# to verify whether the object of A is null with following code,

    A a = new A();
...
    if (a != null)
it will totally wrong, you always need to use if((object)a != null)
but in vb.net you cannot write in this way, you always need to write
    if not a is nothing then
or
    if a isnot nothing then

which just as Christian said, vb.net does not 'expected' anything.

Use !== as != will get you into a world of nontransitive JavaScript truth table weirdness.

Above answers are very elegant. I have written this function long back where i was also struggling to concatenate two dataframe with distinct columns.

Suppose you have dataframe sdf1 and sdf2

from pyspark.sql import functions as F
from pyspark.sql.types import *

def unequal_union_sdf(sdf1, sdf2):
    s_df1_schema = set((x.name, x.dataType) for x in sdf1.schema)
    s_df2_schema = set((x.name, x.dataType) for x in sdf2.schema)

    for i,j in s_df2_schema.difference(s_df1_schema):
        sdf1 = sdf1.withColumn(i,F.lit(None).cast(j))

    for i,j in s_df1_schema.difference(s_df2_schema):
        sdf2 = sdf2.withColumn(i,F.lit(None).cast(j))

    common_schema_colnames = sdf1.columns
    sdk = \
        sdf1.select(common_schema_colnames).union(sdf2.select(common_schema_colnames))
    return sdk 

sdf_concat = unequal_union_sdf(sdf1, sdf2) 

After each command, the exit code can be found in the $? variable so you would have something like:

ls -al file.ext
rc=$?; if [[ $rc != 0 ]]; then exit $rc; fi

You need to be careful of piped commands since the $? only gives you the return code of the last element in the pipe so, in the code:

ls -al file.ext | sed 's/^/xx: /"

will not return an error code if the file doesn't exist (since the sed part of the pipeline actually works, returning 0).

The bash shell actually provides an array which can assist in that case, that being PIPESTATUS. This array has one element for each of the pipeline components, that you can access individually like ${PIPESTATUS[0]}:

pax> false | true ; echo ${PIPESTATUS[0]}
1

Note that this is getting you the result of the false command, not the entire pipeline. You can also get the entire list to process as you see fit:

pax> false | true | false; echo ${PIPESTATUS[*]}
1 0 1

If you wanted to get the largest error code from a pipeline, you could use something like:

true | true | false | true | false
rcs=${PIPESTATUS[*]}; rc=0; for i in ${rcs}; do rc=$(($i > $rc ? $i : $rc)); done
echo $rc

This goes through each of the PIPESTATUS elements in turn, storing it in rc if it was greater than the previous rc value.

Because the original question was never answered, and I had to run into this same problem, the solution for the MD5 problem is that S3 doesn't want the Hex encoded MD5 string we normally think about.

Instead, I had to do this.

// content is a passed in InputStream
byte[] resultByte = DigestUtils.md5(content);
String streamMD5 = new String(Base64.encodeBase64(resultByte));
metaData.setContentMD5(streamMD5);

Essentially what they want for the MD5 value is the Base64 encoded raw MD5 byte-array, not the Hex string. When I switched to this it started working great for me.

To verify that all VC ++ packages are installed and with the latest versions, you can use the tool: http://wampserver.aviatechno.net/files/tools/check_vcredist.exe Also know the difference between VC++ and VS code

Visual Studio is a suite of component-based software development tools and other technologies for building powerful, high-performance applications. On the other hand, Visual Studio Code is detailed as "Build and debug modern web and cloud applications, by Microsoft".

You can do the following:

ssh -t xxx.xxx.xxx.xxx "cd /directory_wanted ; bash --login"

This way, you will get a login shell right on the directory_wanted.

Explanation

-t Force pseudo-terminal allocation. This can be used to execute arbitrary screen-based programs on a remote machine, which can be very useful, e.g. when implementing menu services.

Multiple -t options force tty allocation, even if ssh has no local tty.

• If you don't use -t then no prompt will appear.
• If you don't add ; bash then the connection will get closed and return control to your local machine
• If you don't add bash --login then it will not use your configs because its not a login shell

to Vilx-:

var table = row.parentNode;
while ( table && table.tagName != 'TABLE' )
    table = table.parentNode;

and what if row.parentNode is TBODY?

You should check it out first, and after that do while by .tBodies, probably

 byte[] byteArray = new byte[102400];
 base64String = Base64.encode(byteArray);

That code will encode 102400 bytes, no matter how much data you actually use in the array.

while ((bytesRead = fis.read(byteArray)) != -1)

You need to use the value of bytesRead somewhere.

Also, this may not read the whole file into the array in one go (it only reads as much as is in the I/O buffer), so your loop will probably not work, you may end up with half an image in your array.

I'd use Apache Commons IOUtils here:

 Base64.encode(FileUtils.readFileToByteArray(file));

In this state:

The thread is reading and processing rows for a SELECT statement, and sending data to the client.

Because operations occurring during this this state tend to perform large amounts of disk access (reads).

That's why it takes more time to complete and so is the longest-running state over the lifetime of a given query.

local::lib will help you. It will convince "make install" (and "Build install") to install to a directory you can write to, and it will tell perl how to get at those modules.

In general, if you want to use a module that is in a blib/ directory, you want to say perl -Mblib ... where ... is how you would normally invoke your script.

Refer django docs on static files.

In settings.py:

import os
CURRENT_PATH = os.path.abspath(os.path.dirname(__file__).decode('utf-8'))

MEDIA_ROOT = os.path.join(CURRENT_PATH, 'media')

MEDIA_URL = '/media/'

STATIC_ROOT = 'static/'

STATIC_URL = '/static/'

STATICFILES_DIRS = (
                    os.path.join(CURRENT_PATH, 'static'),
)

Then place your js and css files static folder in your project. Not in media folder.

In views.py:

from django.shortcuts import render_to_response, RequestContext

def view_name(request):
    #your stuff goes here
    return render_to_response('template.html', locals(), context_instance = RequestContext(request))

In template.html:

<link rel="stylesheet" type="text/css" href="{{ STATIC_URL }}css/style.css" />
<script type="text/javascript" src="{{ STATIC_URL }}js/jquery-1.8.3.min.js"></script>

In urls.py:

from django.conf import settings
urlpatterns += patterns('',
    url(r'^media/(?P<path>.*)$', 'django.views.static.serve', {'document_root': settings.MEDIA_ROOT, 'show_indexes': True}),
)

In the detached 'Tool Options' window, click on the red 'X' in the upper right corner to get rid of the window. Then on the main Gimp screen, click on 'Windows,' then 'Dockable Dialogs.' The first entry on its list will be 'Tool Options,' so click on that. Then, Tool Options will appear as a tab in the window on the right side of the screen, along with layers and undo history. Click and drag that tab over to the toolbox window on hte left and drop it inside. The tool options will again be docked in the toolbox.

What worked for me in python 3.7 and img2pdf version 0.4.0 was to use something similar to the code given by Syed Shamikh Shabbir but changing the current working directory using OS as Stu suggested in his comment to Syed's solution

import os
import img2pdf

path = './path/to/folder'
os.chdir(path)
images = [i for i in os.listdir(os.getcwd()) if i.endswith(".jpg")]

for image in images:
    with open(image[:-4] + ".pdf", "wb") as f:
        f.write(img2pdf.convert(image))

It is worth mentioning this solution above saves each .jpg separately in one single pdf. If you want all your .jpg files together in only one .pdf you could do:

import os
import img2pdf

path = './path/to/folder'
os.chdir(path)
images = [i for i in os.listdir(os.getcwd()) if i.endswith(".jpg")]

with open("output.pdf", "wb") as f:
    f.write(img2pdf.convert(images))

Please check this example here: Accessing Structure Members

There is explained that the right way to do it is like this:

strcpy(s1.name , "Egzona");
printf( "Name : %s\n", s1.name);

If you also want to name the constraint, use this:

ALTER TABLE myTable
  ADD CONSTRAINT constraintName 
    UNIQUE (columnName);

Extending @Ryogi answer above, you can take advantage of the lower.tail parameter like so:

qt(0.25/2, 40, lower.tail = FALSE) # 75% confidence

qt(0.01/2, 40, lower.tail = FALSE) # 99% confidence

As well as Amateras you could try Web Tools Project or Aptana. Although they will both give you way more than just a jsp editor.

Edit 2010/10/26 (comment from Simon Gibbs):

The Web Tools Project JSP editor is in the "Web Page Editor (Optional)" project.

Edit 2016/08/16 (extended comment from Dan Carter):

From Kepler (Eclipse 4.3.x) on, this is called "JSF Tools - Web Page Editor".

paramiko.SFTPClient

Sample Usage:

import paramiko
paramiko.util.log_to_file("paramiko.log")

# Open a transport
host,port = "example.com",22
transport = paramiko.Transport((host,port))

# Auth    
username,password = "bar","foo"
transport.connect(None,username,password)

# Go!    
sftp = paramiko.SFTPClient.from_transport(transport)

# Download
filepath = "/etc/passwd"
localpath = "/home/remotepasswd"
sftp.get(filepath,localpath)

# Upload
filepath = "/home/foo.jpg"
localpath = "/home/pony.jpg"
sftp.put(localpath,filepath)

# Close
if sftp: sftp.close()
if transport: transport.close()

foo = {}
foo[#foo+1]="bar"
foo[#foo+1]="baz"

This works because the # operator computes the length of the list. The empty list has length 0, etc.

If you're using Lua 5.3+, then you can do almost exactly what you wanted:

foo = {}
setmetatable(foo, { __shl = function (t,v) t[#t+1]=v end })
_= foo << "bar"
_= foo << "baz"

Expressions are not statements in Lua and they need to be used somehow.

The above claim that "If you are planning to draw a lot of pixel, it's a lot more efficient to use the image data of the canvas to do pixel drawing" seems to be quite wrong - at least with Chrome 31.0.1650.57 m or depending on your definition of "lot of pixel". I would have preferred to comment directly to the respective post - but unfortunately I don't have enough stackoverflow points yet:

I think that I am drawing "a lot of pixels" and therefore I first followed the respective advice for good measure I later changed my implementation to a simple ctx.fillRect(..) for each drawn point, see http://www.wothke.ch/webgl_orbittrap/Orbittrap.htm

Interestingly it turns out the silly ctx.fillRect() implementation in my example is actually at least twice as fast as the ImageData based double buffering approach.

At least for my scenario it seems that the built-in ctx.getImageData/ctx.putImageData is in fact unbelievably SLOW. (It would be interesting to know the percentage of pixels that need to be touched before an ImageData based approach might take the lead..)

Conclusion: If you need to optimize performance you have to profile YOUR code and act on YOUR findings..

If you need just one character and you don't want to keep things in the buffer, you can simply read a whole line and drop everything that isn't needed.

Replace:

stdin.read(1)

with

stdin.readline().strip()[:1]

This will read a line, remove spaces and newlines and just keep the first character.

Simple: When you use curl it encodes the string to utf-8 you just need to decode them..

Description

string utf8_decode ( string $data )

This function decodes data , assumed to be UTF-8 encoded, to ISO-8859-1.

If you're having issues compiling the binary extension, or on a platform where you cant, you can try using the pure python PyMySQL bindings.

Simply pip install pymysql and switch your SQLAlchemy URI to start like this:

SQLALCHEMY_DATABASE_URI = 'mysql+pymysql://.....'

There are some other drivers you could also try.

The safest way would be bitwise OR ing your double with 0. Look at this XORing two doubles in Java

Basically you should do if ((Double.doubleToRawLongBits(foo.x) | 0 ) ) (if it is really 0)

Your web.config file should have this structure:

<configuration>
    <connectionStrings>
        <add name="MyConnectionString" connectionString="..." />
    </connectionStrings>
</configuration>

Then, to create a SQL connection using the connection string named MyConnectionString:

SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["MyConnectionString"].ConnectionString);

If you'd prefer to keep your connection strings in the AppSettings section of your configuration file, it would look like this:

<configuration>
    <appSettings>
        <add key="MyConnectionString" value="..." />
    </appSettings>
</configuration>

And then your SqlConnection constructor would look like this:

SqlConnection con = new SqlConnection(ConfigurationManager.AppSettings["MyConnectionString"]);

If you have a ConstraintLayout with some size, and a child View with some smaller size, you can achieve centering by constraining the child's two edges to the same two edges of the parent. That is, you can write:

app:layout_constraintTop_toTopOf="parent"
app:layout_constraintBottom_toBottomOf="parent"

or

app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"

Because the view is smaller, these constraints are impossible. But ConstraintLayout will do the best it can, and each constraint will "pull" at the child view equally, thereby centering it.

This concept works with any target view, not just the parent.

Below is XML that achieves your desired UI with no nesting of views and no Guidelines (though guidelines are not inherently evil).

Instead of using

response.sendRedirect("/demo.jsp");

Which does a permanent redirect to an absolute URL path,

Rather use RequestDispatcher. Example:

RequestDispatcher dispatcher = request.getRequestDispatcher("demo.jsp");
dispatcher.forward(request, response);

Creating a new list and populating valid values in new list worked for me.

Code throwing error -

List<String> list = new ArrayList<>();
   for (String s: list) {
     if(s is null or blank) {
        list.remove(s);
     }
   }
desiredObject.setValue(list);

After fix -

 List<String> list = new ArrayList<>();
 List<String> newList= new ArrayList<>();
 for (String s: list) {
   if(s is null or blank) {
      continue;
   }
   newList.add(s);
 }
 desiredObject.setValue(newList);

It's really tough to handle a 4G file as such. I used to handle larger text files, but I never used to load them in to my editor. I mostly used UltraEdit in my previous company, now I use Notepad++, but I would get just those parts which i needed to edit. (Most of the cases, the files never needed an edit).

Why do u want to load such a big file in to an editor? When I handled files of these size, I used GNU Core Utils. The most common operations i performed on those files were head ( to get the top 250k lines etc ), tail, split, sort, shuf, uniq etc. It's really powerful.

There's a lot of things you can do with GNU Core Utils. I would definitely recommend those, instead of a new editor.

Just to add to the responses above. I had this same issue when i first started using ASP.Net MVC and i was doing a Response.Redirect during a controller action:

Response.Redirect("/blah", true);

Instead of returning a Response.Redirect action i should have been returning a RedirectAction:

return Redirect("/blah");

In addition to @Ceki 's answer, If you are using logback and setup a config file in your project (usually logback.xml), you can define the log to plot the stack trace as well using

<encoder>
    <pattern>%date |%-5level| [%thread] [%file:%line] - %msg%n%ex{full}</pattern> 
</encoder>

the %ex in pattern is what makes the difference

I had the same problem, but it was a 300GB mysql dump and I wanted to get rid of the DROP and change CREATE TABLE to CREATE TABLE IF NOT EXISTS so didn't want to run two invocations of sed. I wrote this quick Ruby script to dupe the file with those changes:

#!/usr/bin/env ruby

matchers={
    %q/^CREATE TABLE `foo`/ => %q/CREATE TABLE IF NOT EXISTS `foo`/,
    %q/^DROP TABLE IF EXISTS `foo`;.*$/ => "-- DROP TABLE IF EXISTS `foo`;"
}

matchers.each_pair { |m,r|
    STDERR.puts "%s: %s" % [ m, r ]
}

STDIN.each { |line|
    #STDERR.puts "line=#{line}"
    line.chomp!
    unless matchers.length == 0
        matchers.each_pair { |m,r|
            re=/#{m}/
            next if line[re].nil?
            line.sub!(re,r)
            STDERR.puts "Matched: #{m} -> #{r}"
            matchers.delete(m)
            break
        }
    end
    puts line
}

Invoked like

./mreplace.rb < foo.sql > foo_two.sql

Here is some Delphi code to check whether your program is running on a 64 bit operating system:

function Is64BitOS: Boolean;
{$IFNDEF WIN64}
type
  TIsWow64Process = function(Handle:THandle; var IsWow64 : BOOL) : BOOL; stdcall;
var
  hKernel32 : Integer;
  IsWow64Process : TIsWow64Process;
  IsWow64 : BOOL;
{$ENDIF}
begin
  {$IFDEF WIN64}
     //We're a 64-bit application; obviously we're running on 64-bit Windows.
     Result := True;
  {$ELSE}
  // We can check if the operating system is 64-bit by checking whether
  // we are running under Wow64 (we are 32-bit code). We must check if this
  // function is implemented before we call it, because some older 32-bit 
  // versions of kernel32.dll (eg. Windows 2000) don't know about it.
  // See "IsWow64Process", http://msdn.microsoft.com/en-us/library/ms684139.aspx
  Result := False;
  hKernel32 := LoadLibrary('kernel32.dll');
  if hKernel32 = 0 then RaiseLastOSError;
  try
    @IsWow64Process := GetProcAddress(hkernel32, 'IsWow64Process');
    if Assigned(IsWow64Process) then begin
      if (IsWow64Process(GetCurrentProcess, IsWow64)) then begin
        Result := IsWow64;
      end
      else RaiseLastOSError;
    end;
  finally
    FreeLibrary(hKernel32);
  end;  
  {$ENDIf}
end;

Use ng-value instead of value.

ng-value="true"

Version with ng-checked is worse because of the code duplication.

Sohnee solutions is cleaner, but you can also try

window["bootbox"]

TextView textv = (TextView) findViewById(R.id.textview1);
textv.setShadowLayer(1, 0, 0, Color.BLACK);

As Josh has stated above, you want to give each one the same name (letter, button, etc.) and all of them work. Then you want to surround all of these with a form tag:

<form name="myLetters" action="yourScript.php" method="POST">
<!-- Enter your values here with the following syntax: -->
<input type="radio" name="letter" value="A" /> A
<!-- Then add a submit value & close your form -->
<input type="submit" name="submit" value="Choose Letter!" />
</form>

Then, in the PHP script "yourScript.php" as defined by the action attribute, you can use:

$_POST['letter']

To get the value chosen.

How about this? Just give it a thought-

import java.util.ArrayList;

class Solution
{
        public static void main (String[] args){

             ArrayList<String> List_Of_Array = new ArrayList<String>();
             List_Of_Array.add("A");
             List_Of_Array.add("B");
             List_Of_Array.add("C");
             List_Of_Array.add("D");
             List_Of_Array.add("E");
             List_Of_Array.add("F");
             List_Of_Array.add("G");
             List_Of_Array.add("H");

             int i[] = {1,3,5};

             for (int j = 0; j < i.length; j++) {
                 List_Of_Array.remove(i[j]-j);
             }

             System.out.println(List_Of_Array);

        }


}

And the output was-

[A, C, E, G, H]

So unfortunately, after trying all the answers from above, I did not get them to work after tireless times of trying. So I decided to do the real hack myself and I go this to work for me. I trust it would work perfectly for you too.

I am using this simple method to get the width of an image generated by the app and yet to be upload later for verification :

Pls. take note : you would have to enable permissions in manifest for access storage.

/I made it static and put in my Global class so I can reference or access it from just one source and if there is any modification, it would all have to be done at just one place. Just maintaining a DRY concept in java. (anyway) :)/

public static int getImageWidthOrHeight(String imgFilePath) {

            Log.d("img path : "+imgFilePath);

            // Decode image size
            BitmapFactory.Options o = new BitmapFactory.Options();
            o.inJustDecodeBounds = true;
            BitmapFactory.decodeFile(imgFilePath, o);

            int width_tmp = o.outWidth, height_tmp = o.outHeight;

            Log.d("Image width : ", Integer.toString(width_tmp) );

            //you can decide to rather return height_tmp to get the height.

            return width_tmp;

}

You might also consider removing the need for duplicated parameter names in your Sql by changing your Sql to

table.Variable2 LIKE '%' || :VarB || '%'

and then getting your client to provide '%' for any value of VarB instead of null. In some ways I think this is more natural.

You could also change the Sql to

table.Variable2 LIKE '%' || IfNull(:VarB, '%') || '%'

add these dependecies to your .pom file:

Distinguish between static analysis and runtime analysis. Use static analysis for internal stuff, and runtime analysis for the public boundaries of your code.

For things that should not be null:

• Runtime check: Use "if (x == null) ..." (zero dependency) or @javax.validation.NotNull (with bean validation) or @lombok.NonNull (plain and simple) or guavas Preconditions.checkNotNull(...)

  • Use Optional for method return types (only). Either Java8 or Guava.

• Static check: Use an @NonNull annotation

• Where it fits, use @...NonnullByDefault annotations on class or package level. Create these annotations yourself (examples are easy to find).
  • Else, use @...CheckForNull on method returns to avoid NPEs

This should give the best result: warnings in the IDE, errors by Findbugs and checkerframework, meaningful runtime exceptions.

Do not expect static checks to be mature, their naming is not standardized and different libraries and IDEs treat them differently, ignore them. The JSR305 javax.annotations.* classes look like standard, but they are not, and they cause split packages with Java9+.

Some notes explanations:

• Findbugs/spotbugs/jsr305 annotations with package javax.validation.* clash with other modules in Java9+, also possibly violate Oracle license
• Spotbugs annotations still depends on jsr305/findbugs annotations at compiletime (at the time of writing https://github.com/spotbugs/spotbugs/issues/421)
• jetbrains @NotNull name conflicts with @javax.validation.NotNull.
• jetbrains, eclipse or checkersframework annotations for static checking have the advantage over javax.annotations that they do not clash with other modules in Java9 and higher
• @javax.annotations.Nullable does not mean to Findbugs/Spotbugs what you (or your IDE) think it means. Findbugs will ignore it (on members). Sad, but true (https://sourceforge.net/p/findbugs/bugs/1181)
• For static checking outside an IDE, 2 free tools exist: Spotbugs(formerly Findbugs) and checkersframework.
• The Eclipse library has @NonNullByDefault, jsr305 only has @ParametersAreNonnullByDefault. Those are mere convenience wrappers applying base annotations to everything in a package (or class), you can easily create your own. This can be used on package. This may conflict with generated code (e.g. lombok).
• Using lombok as an exported dependency should be avoided for libraries that you share with other people, the less transitive dependencies, the better
• Using Bean validation framework is powerful, but requires high overhead, so that's overkill just to avoid manual null checking.
• Using Optional for fields and method parameters is controversial (you can find articles about it easily)
• Android null annotations are part of the Android support library, they come with a whole lot of other classes, and don't play nicely with other annotations/tools

Before Java9, this is my recommendation:

// file: package-info.java
@javax.annotation.ParametersAreNonnullByDefault
package example;


// file: PublicApi
package example;

public interface PublicApi {

    Person createPerson(
        // NonNull by default due to package-info.java above
        String firstname,
        String lastname);
}

// file: PublicApiImpl
public class PublicApiImpl implements PublicApi {
    public Person createPerson(
            // In Impl, handle cases where library users still pass null
            @Nullable String firstname, // Users  might send null
            @Nullable String lastname // Users might send null
            ) {
        if (firstname == null) throw new IllagalArgumentException(...);
        if (lastname == null) throw new IllagalArgumentException(...);
        return doCreatePerson(fistname, lastname, nickname);
    }

    @NonNull // Spotbugs checks that method cannot return null
    private Person doCreatePerson(
             String firstname, // Spotbugs checks null cannot be passed, because package has ParametersAreNonnullByDefault
             String lastname,
             @Nullable String nickname // tell Spotbugs null is ok
             ) {
         return new Person(firstname, lastname, nickname);
    }

    @CheckForNull // Do not use @Nullable here, Spotbugs will ignore it, though IDEs respect it
    private Person getNickname(
         String firstname,
         String lastname) {
         return NICKNAMES.get(firstname + ':' + lastname);
    }
}

Note that there is no way to make Spotbugs raise a warning when a nullable method parameter is dereferenced (at the time of writing, version 3.1 of Spotbugs). Maybe checkerframework can do that.

Sadly these annotations do not distinguish between the cases of a public method of a library with arbitrary callsites, and non-public methods where each callsite can be known. So the double meaning of: "Indicate that null is undesired, but prepare for null being passed nevertheless" is not possible in a single declaration, hence the above example has different annotations for the interface and the implementation.

For cases where the split interface approach is not practical, the following approach is a compromise:

        public Person createPerson(
                @NonNull String firstname,
                @NonNull String lastname
                ) {
            // even though parameters annotated as NonNull, library clients might call with null.
            if (firstname == null) throw new IllagalArgumentException(...);
            if (lastname == null) throw new IllagalArgumentException(...);
            return doCreatePerson(fistname, lastname, nickname);
        }

This helps clients to not pass null (writing correct code), while returning useful errors if they do.

Try executing :

sudo ./adb kill-server

sudo ./adb start-server

sudo ./adb devices

Very simple use of any

df <- <your structure>

df$Den <- apply(df,1,function(i) {ifelse(any(is.na(i)) | any(i != 1), 0, 1)})

No, you can't.

But as a solid workaround, I would suggest to classify that first div as position:relative and use div::before to create an underlying element containing your image. Classified as position:absolute you can move it anywhere relative to your initial div.

Don't forget to add content to that new element. Here's some example:

div {
  position: relative;
}    

div::before {
  content: ""; /* empty but necessary */
  position: absolute;
  background: ...
}

Note: if you want it to be 'on top' of the parent div, use div::after instead.

Yes, you can invalidate cache.

The cache is stored in an object called require.cache which you can access directly according to filenames (e.g. - /projects/app/home/index.js as opposed to ./home which you would use in a require('./home') statement).

delete require.cache['/projects/app/home/index.js'];

Our team has found the following module useful. To invalidate certain groups of modules.

https://www.npmjs.com/package/node-resource

The date should take the format YYYY-MM-DD. Single digit days and months should be padded with a 0. January is 01.

From the documentation:

A string representing a date.

Value: A valid full-date as defined in [RFC 3339], with the additional qualification that the year component is four or more digits representing a number greater than 0.

Your code should be altered to:

<input type="date" value="2013-01-08">

Example jsfiddle

You can also request for access programmatically, which I prefer because in most cases you need to know if you took the access or not.

Swift 4 update:

    //Camera
    AVCaptureDevice.requestAccess(for: AVMediaType.video) { response in
        if response {
            //access granted
        } else {

        }
    }

    //Photos
    let photos = PHPhotoLibrary.authorizationStatus()
    if photos == .notDetermined {
        PHPhotoLibrary.requestAuthorization({status in
            if status == .authorized{
                ...
            } else {}
        })
    }

You do not share code so I cannot be sure if this would be useful for you, but general speaking use it as a best practice.

A very simple method is to use apkanalyzer.

apkanalyzer manifest application-id "${_path_to_apk}"

hope this helps someone:

$('#id')
        .autocomplete({
            source: hints_array,
            minLength: 0, //how many chars to start search for
            position: { my: "left bottom", at: "left top", collision: "flip" } // so that it automatically flips the autocomplete above the input if at the bottom
            })
        .focus(function() {
        $(this).autocomplete('search', $(this).val()) //auto trigger the search with whatever's in the box
        })

Use LayoutParams (as explained already). However be careful which LayoutParams to choose. According to https://stackoverflow.com/a/11971553/3184778 "you need to use the one that relates to the PARENT of the view you're working on, not the actual view"

If for example the TextView is inside a TableRow, then you need to use TableRow.LayoutParams instead of RelativeLayout or LinearLayout

Use d-flex instead of row for "tr" in Bootstrap 4

The thing is that "row" class takes more width then the parent container, which introduces issues.

<table class="table">_x000D_
  <tbody>_x000D_
    <tr class="d-flex">_x000D_
      <td class="col-sm-8">Hello</td>_x000D_
      <td class="col-sm-4">World</td>_x000D_
    </tr>_x000D_
    <tr class="d-flex">_x000D_
      <td class="col-sm-8">8 columns</td>_x000D_
      <td class="col-sm-4">4 columns</td>_x000D_
    </tr>_x000D_
  </tbody>_x000D_
</table>

I've just tried that myself, and it gave me a 200 OK response, but no content - the content length was 0. Are you sure it's giving you content? Anyway, I'll assume that you've really got content.

Getting actual text back relies on knowing the encoding, which can be tricky. It should be in the Content-Type header, but then you've got to parse it etc.

However, if this is actually XML (e.g. from "http://google.com/xrds/xrds.xml"), it's a lot easier. Just load the XML into memory, e.g. via LINQ to XML. For example:

using System;
using System.IO;
using System.Net;
using System.Xml.Linq;
using System.Web;

class Test
{
    static void Main()
    {
        string url = "http://google.com/xrds/xrds.xml";
        HttpWebRequest request = (HttpWebRequest) WebRequest.Create(url);

        XDocument doc;
        using (WebResponse response = request.GetResponse())
        {
            using (Stream stream = response.GetResponseStream())
            {
                doc = XDocument.Load(stream);
            }
        }
        // Now do whatever you want with doc here
        Console.WriteLine(doc);
    }   
}

If the content is XML, getting the result into an XML object model (whether it's XDocument, XmlDocument or XmlReader) is likely to be more valuable than having the plain text.

Modern browsers support a Content Security Policy or CSP. This is the highest level of web security and strongly recommended if you can apply it because it completely blocks all XSS attacks.

Both of your suggestions break with CSP enabled because they allow inline Javascript (which could be injected by a hacker) to execute in your page.

The best practice is to subscribe to the event in Javascript, as in Konrad Rudolph's answer.

You can also use the built-in template filter default:

If value evaluates to False (e.g. None, an empty string, 0, False); the default "--" is displayed.

{{ profile.user.first_name|default:"--" }}

Documentation: https://docs.djangoproject.com/en/dev/ref/templates/builtins/#default

Just added ignore: [] in the specific page for the specific form, this solution worked for me.

$("#form_name").validate({
        ignore: [],
        onkeyup: false,
        rules: {            
        },      
        highlight:false,
    });

Material please go through this Link And also try this

 ArrayList<Class> myArray= new ArrayList<Class>();

How is the column defined? If its a varchar field, then its not a number (or stored as one). Oracle may be able to do the conversion for you (eg, select * from someTable where charField = 0), but it will only return rows where the conversion holds true and is possible. This is also far from ideal situation performance wise.

So, if you want to do number comparisons and treat this column as a number, perhaps it should be defined as a number?

That said, here's what you might do:

create or replace function myToNumber(i_val in varchar2) return number is
 v_num number;
begin
 begin
   select to_number(i_val) into v_num from dual;
 exception
   when invalid_number then
   return null;
 end;
 return v_num;
end;

You might also include the other parameters that the regular to_number has. Use as so:

select * from someTable where myToNumber(someCharField) > 0;

It won't return any rows that Oracle sees as an invalid number.

Cheers.

Try:

if (isset($_FILES['uploaded_file']) &&
    $_FILES['uploaded_file']['error'] == UPLOAD_ERR_OK) {
    $mail->AddAttachment($_FILES['uploaded_file']['tmp_name'],
                         $_FILES['uploaded_file']['name']);
}

Basic example can also be found here.

The function definition for AddAttachment is:

public function AddAttachment($path,
                              $name = '',
                              $encoding = 'base64',
                              $type = 'application/octet-stream')

SELECT * FROM products WHERE catid IN ('1', '2', '3', '4')

Try disabling Just My Code (JMC).

• Tools -> Options -> Debugger
• Uncheck "Enable Just my Code"

By default the debugger tries to restrict the view of the world to code that is only contained within your solution. This is really heplful at times but when you want to debug code which is not in your solution (as is your situation) you need to disable JMC in order to see it. Otherwise the code will be treated as external and largely hidden from your view.

EDIT

When you're broken in your code try the following.

• Debug -> Windows -> Modules
• Find the DLL for the project you are interested in
• Right Click -> Load Symbols -> Select the Path to the .PDB for your other project

If you have the files written under .gitignore, remove the files and run git pull again. That helped me out.

use Handler

new Handler(Looper.getMainLooper()).post(new Runnable() {
    @Override
    public void run() {
        // Code here will run in UI thread
    }
});

every minute:

* * * * * /path/to/php /var/www/html/a.php

every 24hours (every midnight):

It is better to process HTML as a template than to build nodes via JavaScript (HTML is not XML after all.) You can keep your IFRAME's HTML syntax clean by using a template and then appending the template's contents into another DIV.

<div id="placeholder"></div>

<script id="iframeTemplate" type="text/html">
    <iframe src="...">
        <!-- replace this line with alternate content -->
    </iframe>
</script>

<script type="text/javascript">
var element,
    html,
    template;

element = document.getElementById("placeholder");
template = document.getElementById("iframeTemplate");
html = template.innerHTML;

element.innerHTML = html;
</script>

You can have only one default export which you declare like:

export default App; or export default class App extends React.Component {...

and later do import App from './App'

If you want to export something more you can use named exports which you declare without default keyword like:

export {
  About,
  Contact,
}

or:

export About;
export Contact;

or:

export const About = class About extends React.Component {....
export const Contact = () => (<div> ... </div>);

and later you import them like:

import App, { About, Contact } from './App';

EDIT:

There is a mistake in the tutorial as it is not possible to make 3 default exports in the same main.js file. Other than that why export anything if it is no used outside the file?. Correct main.js :

import React from 'react';
import ReactDOM from 'react-dom';
import { Router, Route, Link, browserHistory, IndexRoute  } from 'react-router'

class App extends React.Component {
...
}

class Home extends React.Component {
...
}


class About extends React.Component {
...
}


class Contact extends React.Component {
...
}


ReactDOM.render((
   <Router history = {browserHistory}>
      <Route path = "/" component = {App}>
         <IndexRoute component = {Home} />
         <Route path = "home" component = {Home} />
         <Route path = "about" component = {About} />
         <Route path = "contact" component = {Contact} />
      </Route>
   </Router>

), document.getElementById('app'))

EDIT2:

another thing is that this tutorial is based on react-router-V3 which has different api than v4.

On declaration you can do the following.

float[] values = {0.1f, 0.2f, 0.3f};

When the field is already defined, try this.

values = new float[] {0.1f, 0.2f, 0.3f};

Be aware that also the second version creates a new array. If values was the only reference to an already existing field, it becomes eligible for garbage collection.

This problem occurs if you are using a backwards compatible sheet (a .xls) instead of a .xlsx

To allow sheets to be opened in pre office 2007 version it can't contain more than 65k rows. You can check the number of rows in your sheet by using ctrl+arrowdown till you hit the bottom. If you try to get a range larger than that number of rows it will create an error

To convert any object to string there are several methods in Java

String convertedToString = String.valueOf(Object);  //method 1

String convertedToString = "" + Object;   //method 2

String convertedToString = Object.toString();  //method 3

I would prefer the first and third

EDIT
If working in kotlin, the official android language

val number: Int = 12345
String convertAndAppendToString = "number = $number"   //method 1

String convertObjectMemberToString = "number = ${Object.number}" //method 2

String convertedToString = Object.toString()  //method 3

I had a similar need, in which I wanted to use the output of last command into the next one. Much like a | (pipe). eg

$ which gradle 
/usr/bin/gradle
$ ls -alrt /usr/bin/gradle

to something like -

$ which gradle |: ls -altr {}

Solution : Created this custom pipe. Really simple, using xargs -

$ alias :='xargs -I{}'

Basically nothing by creating a short hand for xargs, it works like charm, and is really handy. I just add the alias in .bash_profile file.

First of all tried many solutions, then I just deleted the folder in which I was having trouble.

And then performed SVN Update.

That worked for me.

I would not recommend it, but nothing worked but this. :(

The shorter ES6 version of the answer:

const delay = t => new Promise(resolve => setTimeout(resolve, t));

And then you can do:

delay(3000).then(() => console.log('Hello'));

In my case URI, as it was defined on FB, was fine, but I was using Spring Security and it was adding ;jsessionid=0B9A5E71DAA32A01A3CD351E6CA1FCDD to my URI so, it caused the mismatching.

https://m.facebook.com/v2.5/dialog/oauth?client_id=your-fb-id-code&response_type=code&redirect_uri=https://localizator.org/auth/facebook;jsessionid=0B9A5E71DAA32A01A3CD351E6CA1FCDD&scope=email&state=b180578a-007b-48bc-bd81-4b08c6989e18

In order to avoid the URL rewriting I added disable-url-rewriting="true" to Spring Security config, in this way:

<http auto-config="true" access-denied-page="/security/accessDenied" use-expressions="true"
      disable-url-rewriting="true" entry-point-ref="authenticationEntryPoint"/> 

And it fixed my problem.

I was also facing the same issue where I was receiving the Transaction_Date as YYYYMMDD in bigint format. So I converted it into Datetime format using below query and saved it in new column with datetime format. I hope this will help you as well.

SELECT
convert( Datetime, STUFF(STUFF(Transaction_Date, 5, 0, '-'), 8, 0, '-'), 120) As [Transaction_Date_New]
FROM mydb

One possible solution:-

Summary: make sure you are using import com.yourpkgdomainname.yourpkgappname.R instead of import android.R

Details: The problem occured when I changed ID of a label which was being referred in other places in the layout XML file. Due to this error, the R file stopped generating at first. Eclipse is bad in handling errors with the layout files.

When I corrected the ID reference (with project clean few times and Eclipse restarts, I noticed that my import packages now has:
import android.R

Changing it to following fixed the error:
import com.example.app.R

Place this at the top of your script. It will cause the script to prompt the user for a password. The resulting password can then be used elsewhere in your script via $pw.

   Param(
     [Parameter(Mandatory=$true, Position=0, HelpMessage="Password?")]
     [SecureString]$password
   )

   $pw = [Runtime.InteropServices.Marshal]::PtrToStringAuto([Runtime.InteropServices.Marshal]::SecureStringToBSTR($password))

If you want to debug and see the value of the password you just read, use:

   write-host $pw

If you have Iterable convert to stream and find last element

 Iterator<String> sourceIterator = Arrays.asList("one", "two", "three").iterator();

 Iterable<String> iterable = () -> sourceIterator;


 String last = StreamSupport.stream(iterable.spliterator(), false).reduce((first, second) -> second).orElse(null);

A comment to jarijira

Well I have had many issues with .html and .empty() methods for inputs o. If the id represents an input and not another type of html selector like

or use the .val() function to manipulate.

For example: this is the proper way to manipulate input values

<textarea class="form-control" id="someInput"></textarea>

$(document).ready(function () {
     var newVal='test'
     $('#someInput').val('') //clear input value
     $('#someInput').val(newVal) //override w/ the new value
     $('#someInput').val('test2) 
     newVal= $('#someInput').val(newVal) //get input value

}

For improper, but sometimes works For example: this is the proper way to manipulate input values

<textarea class="form-control" id="someInput"></textarea>

$(document).ready(function () {
     var newVal='test'
     $('#someInput').html('') //clear input value
     $('#someInput').empty() //clear html inside of the id
     $('#someInput').html(newVal) //override the html inside of text area w/ string could be '<div>test3</div>
     really overriding with a string manipulates the value, but this is not the best practice as you do not put things besides strings or values inside of an input. 
     newVal= $('#someInput').val(newVal) //get input value

}

An issue that I had was I was using the $getJson method and I was indeed able to use .html calls to manipulate my inputs. However, whenever I had an error or fail on the getJSON I could no longer change my inputs using the .clear and .html calls. I could still return the .val(). After some experimentation and research I discovered that you should only use the .val() function to make changes to input fields.

Here's a function that can include an optional offset for those fixed headers. No external libraries needed.

function scrollIntoView(selector, offset = 0) {
  window.scroll(0, document.querySelector(selector).offsetTop - offset);
}

You can grab the height of an element using JQuery and scroll to it.

var headerHeight = $('.navbar-fixed-top').height();
scrollIntoView('#some-element', headerHeight)

Update March 2018

Scroll to this answer without using JQuery

scrollIntoView('#answer-44786637', document.querySelector('.top-bar').offsetHeight)

Be sure to stringify before sending. I leaned on the libraries too much and thought they would encode properly based on the contentType I was posting, but they do not seem to.

Works:

$.ajax({
    url: _saveAllDevicesUrl
,   type: 'POST'
,   contentType: 'application/json'
,   data: JSON.stringify(postData) //stringify is important
,   success: _madeSave.bind(this)
});

I prefer this method to using a plugin like $.toJSON, although that does accomplish the same thing.

Here's a setTimeout equivalent, mostly useful when trying to update the User Interface after a delay.

As you may know, updating the user interface can only by done from the UI thread. AsyncTask does that for you by calling its onPostExecute method from that thread.

new AsyncTask<Void, Void, Void>() {
        @Override
        protected Void doInBackground(Void... params) {
            try {
                Thread.sleep(5000);
            } catch (InterruptedException e) {
            }

            return null;
        }

        @Override
        protected void onPostExecute(Void result) {
            // Update the User Interface
        }

    }.execute();

This will insert a new element after the input field with id "password".

$(document).ready(function(){
  var newInput = $("<input name='new_field' type='text'>");
  $('input#password').after(newInput);
});

Not sure if this answers your question.

Use the FileSystemObject object, namely, its CreateFolder and CopyFile methods. Basically, this is what your script will look like:

Dim oFSO
Set oFSO = CreateObject("Scripting.FileSystemObject")

' Create a new folder
oFSO.CreateFolder "C:\MyFolder"

' Copy a file into the new folder
' Note that the destination folder path must end with a path separator (\)
oFSO.CopyFile "\\server\folder\file.ext", "C:\MyFolder\"

You may also want to add additional logic, like checking whether the folder you want to create already exists (because CreateFolder raises an error in this case) or specifying whether or not to overwrite the file being copied. So, you can end up with this:

Const strFolder = "C:\MyFolder\", strFile = "\\server\folder\file.ext"
Const Overwrite = True
Dim oFSO

Set oFSO = CreateObject("Scripting.FileSystemObject")

If Not oFSO.FolderExists(strFolder) Then
  oFSO.CreateFolder strFolder
End If

oFSO.CopyFile strFile, strFolder, Overwrite

I think Compiling Python Code would be a good place to start:

Python source code is automatically compiled into Python byte code by the CPython interpreter. Compiled code is usually stored in PYC (or PYO) files, and is regenerated when the source is updated, or when otherwise necessary.

To distribute a program to people who already have Python installed, you can ship either the PY files or the PYC files. In recent versions, you can also create a ZIP archive containing PY or PYC files, and use a small “bootstrap script” to add that ZIP archive to the path.

To “compile” a Python program into an executable, use a bundling tool, such as Gordon McMillan’s installer (alternative download) (cross-platform), Thomas Heller’s py2exe (Windows), Anthony Tuininga’s cx_Freeze (cross-platform), or Bob Ippolito’s py2app (Mac). These tools puts your modules and data files in some kind of archive file, and creates an executable that automatically sets things up so that modules are imported from that archive. Some tools can embed the archive in the executable itself.

For the best performance and zero garbage, use this:

using System;
using T = MyNamespace.MyFlags;

All of todays browsers use at least version 1.5:

Concerning your tutorial site, the information there seems to be extremely outdated, I beg you to head over to MDC and read their Guide:
https://developer.mozilla.org/en/JavaScript/Guide

You may still want to watch out for features which require version 1.6 or above, as this might give Internet Explorer some troubles.

The reason you separate the login and non-login shell is because the .bashrc file is reloaded every time you start a new copy of Bash. The .profile file is loaded only when you either log in or use the appropriate flag to tell Bash to act as a login shell.

Personally,

• I put my PATH setup into a .profile file (because I sometimes use other shells);
• I put my Bash aliases and functions into my .bashrc file;

• I put this

  #!/bin/bash
  #
  # CRM .bash_profile Time-stamp: "2008-12-07 19:42"
  #
  # echo "Loading ${HOME}/.bash_profile"
  source ~/.profile # get my PATH setup
  source ~/.bashrc  # get my Bash aliases
  

  in my .bash_profile file.

Oh, and the reason you need to type bash again to get the new alias is that Bash loads your .bashrc file when it starts but it doesn't reload it unless you tell it to. You can reload the .bashrc file (and not need a second shell) by typing

source ~/.bashrc

which loads the .bashrc file as if you had typed the commands directly to Bash.

do this on a new thread (seperate it from main thread)

 new Thread(new Runnable() {
     @Override
     public void run() {
        // TODO Auto-generated method stub
     }
}).run();

To define an array of strings it is more comfortable to use $var = @('User1 ', 'User2 ').

$servername = hostname
$smtpserver = 'localhost'
$emailTo = @('username1 <[email protected]>', 'username2<[email protected]>')
$emailFrom = 'SomeServer <[email protected]>'
Send-MailMessage -To $emailTo -Subject 'Low available memory' -Body 'Warning' -SmtpServer $smtpserver -From $emailFrom

When looking for files to potentially add. The output from git show does that but it also includes a lot of other stuff. The following command is useful to get the same list of files but without all of the other stuff.

 git status --porcelain | grep "^?? " | sed -e 's/^[?]* //'

This is useful when combined in a pipeline to find files matching a specific pattern and then piping that to git add.

git status --porcelain | grep "^?? "  | sed -e 's/^[?]* //' | \
egrep "\.project$|\.settings$\.classfile$" | xargs -n1 git add

Try ContentTemplate:

<Button Grid.Row="2" Grid.Column="0" Width="20" Height="20"
        Template="{StaticResource SomeTemplate}">
    <Button.ContentTemplate>
        <DataTemplate>
            <Image Source="../Folder1/Img1.png" Width="20" />
        </DataTemplate>
    </Button.ContentTemplate>
</Button>

Just use:

$('#selectedDueDate').val(dateText).trigger('input');

instead of:

$('#selectedDueDate').val(dateText);

var myCallback = function(data) {
  console.log('got data: '+data);
};

var usingItNow = function(callback) {
  callback('get it?');
};

Now open node or browser console and paste the above definitions.

Finally use it with this next line:

usingItNow(myCallback);

With Respect to the Node-Style Error Conventions

Costa asked what this would look like if we were to honor the node error callback conventions.

In this convention, the callback should expect to receive at least one argument, the first argument, as an error. Optionally we will have one or more additional arguments, depending on the context. In this case, the context is our above example.

Here I rewrite our example in this convention.

var myCallback = function(err, data) {
  if (err) throw err; // Check for the error and throw if it exists.
  console.log('got data: '+data); // Otherwise proceed as usual.
};

var usingItNow = function(callback) {
  callback(null, 'get it?'); // I dont want to throw an error, so I pass null for the error argument
};

If we want to simulate an error case, we can define usingItNow like this

var usingItNow = function(callback) {
  var myError = new Error('My custom error!');
  callback(myError, 'get it?'); // I send my error as the first argument.
};

The final usage is exactly the same as in above:

usingItNow(myCallback);

The only difference in behavior would be contingent on which version of usingItNow you've defined: the one that feeds a "truthy value" (an Error object) to the callback for the first argument, or the one that feeds it null for the error argument.

Here's a simple circle_background.xml for pre-material:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true">
        <shape android:shape="oval">
            <solid android:color="@color/color_accent_dark" />
        </shape>
    </item>
    <item>
        <shape android:shape="oval">
            <solid android:color="@color/color_accent" />
        </shape>
    </item>
</selector>

You can use with the attribute 'android:background="@drawable/circle_background" in your button's layout definition

Your code has no problem. It does print the way you want. Alternatively, you can do this:

printf("%04x",a);

Easiest solution is to create the column using the correct data type: DATE

For example:

1. Create table:

   create table test_date (mydate date);

2. Insert row:

   insert into test_date values (to_date('01-01-2011','dd-mm-yyyy'));

To get the month and year, do as follows:

select to_char(mydate, 'MM-YYYY') from test_date;

Your result will be as follows: 01-2011

Another cool function to use is "EXTRACT"

select extract(year from mydate) from test_date;

This will return: 2011

Skipping Terminal setup since you mentioned applications, permanent system environment variable set up (works for macOS Sierra; should work for El Capitan too):

launchctl setenv JAVA_HOME $(/usr/libexec/java_home -v 1.8)

(this will set JAVA_HOME to the latest 1.8 JDK, chances are you have gone through serveral updates e.g. javac 1.8.0_101, javac 1.8.0_131)
Of course, change 1.8 to 1.7 or 1.6 (really?) to suit your need and your system

sp_help will give you a whole bunch of information about a table including the columns, keys and constraints. For example, running

exec sp_help 'Address' 

will give you information about Address.

This works:

$('#textareaName').val('');

Control characters:

(Hex codes assume an ASCII-compatible character encoding.)

• \a = \x07 = alert (bell)
• \b = \x08 = backspace
• \t = \x09 = horizonal tab
• \n = \x0A = newline (or line feed)
• \v = \x0B = vertical tab
• \f = \x0C = form feed
• \r = \x0D = carriage return
• \e = \x1B = escape (non-standard GCC extension)

Punctuation characters:

• \" = quotation mark (backslash not required for '"')
• \' = apostrophe (backslash not required for "'")
• \? = question mark (used to avoid trigraphs)
• \\ = backslash

Numeric character references:

• \ + up to 3 octal digits
• \x + any number of hex digits
• \u + 4 hex digits (Unicode BMP, new in C++11)
• \U + 8 hex digits (Unicode astral planes, new in C++11)

\0 = \00 = \000 = octal ecape for null character

If you do want an actual digit character after a \0, then yes, I recommend string concatenation. Note that the whitespace between the parts of the literal is optional, so you can write "\0""0".

I get the same error in WP when I use php ver 7.1.6 - just take your php version back to 7.0.20 and the error will disappear.

Well, actually I'll have to say David is right with his solution, but there are some topics disturbing me:

1. You should never send your model to the view => This is correct
2. If you create a ViewModel, and include the Model as member in the ViewModel, then you effectively sent your model to the View => this is BAD
3. Using dictionaries to send the options to the view => this not good style

So how can you create a better coupling?

I would use a tool like AutoMapper or ValueInjecter to map between ViewModel and Model. AutoMapper does seem to have the better syntax and feel to it, but the current version lacks a very severe topic: It is not able to perform the mapping from ViewModel to Model (under certain circumstances like flattening, etc., but this is off topic) So at present I prefer to use ValueInjecter.

So you create a ViewModel with the fields you need in the view. You add the SelectList items you need as lookups. And you add them as SelectLists already. So you can query from a LINQ enabled sourc, select the ID and text field and store it as a selectlist: You gain that you do not have to create a new type (dictionary) as lookup and you just move the new SelectList from the view to the controller.

  // StaffTypes is an IEnumerable<StaffType> from dbContext
  // viewModel is the viewModel initialized to copy content of Model Employee  
  // viewModel.StaffTypes is of type SelectList

  viewModel.StaffTypes =
    new SelectList(
        StaffTypes.OrderBy( item => item.Name )
        "StaffTypeID",
        "Type",
        viewModel.StaffTypeID
    );

In the view you just have to call

@Html.DropDownListFor( model => mode.StaffTypeID, model.StaffTypes )

Back in the post element of your method in the controller you have to take a parameter of the type of your ViewModel. You then check for validation. If the validation fails, you have to remember to re-populate the viewModel.StaffTypes SelectList, because this item will be null on entering the post function. So I tend to have those population things separated into a function. You just call back return new View(viewModel) if anything is wrong. Validation errors found by MVC3 will automatically be shown in the view.

If you have your own validation code you can add validation errors by specifying which field they belong to. Check documentation on ModelState to get info on that.

If the viewModel is valid you have to perform the next step:

If it is a create of a new item, you have to populate a model from the viewModel (best suited is ValueInjecter). Then you can add it to the EF collection of that type and commit changes.

If you have an update, you get the current db item first into a model. Then you can copy the values from the viewModel back to the model (again using ValueInjecter gets you do that very quick). After that you can SaveChanges and are done.

Feel free to ask if anything is unclear.

Adding dependencies didn't fix the issue at my end.

The issue was happening at my end because of "additional" fields that are part of the "@Entity" class and don't exist in the database.

I removed the additional fields from the @Entity class and it worked.
