For Swift 3 and XCode 8, this worked. Follow below steps to achieve this:-

viewDidLoad()
    {
        let layout: UICollectionViewFlowLayout = UICollectionViewFlowLayout()
        var width = UIScreen.main.bounds.width
        layout.sectionInset = UIEdgeInsets(top: 0, left: 5, bottom: 0, right: 5)
    width = width - 10
    layout.itemSize = CGSize(width: width / 2, height: width / 2)
        layout.minimumInteritemSpacing = 0
        layout.minimumLineSpacing = 0
        collectionView!.collectionViewLayout = layout
    }

TL;DR: Scan down to image, and then check out working project here.

Updating my answer for a simpler solution that I found..

In my case, I wanted to fix the width, and have variable height cells. I wanted a drop in, reusable solution that handled rotation and didn't require a lot of intervention.

What I arrived at, was override (just) systemLayoutFitting(...) in the collection cell (in this case a base class for me), and first defeat UICollectionView's effort to set the wrong dimension on contentView by adding a constraint for the known dimension, in this case, the width.

class EstimatedWidthCell: UICollectionViewCell {
    override init(frame: CGRect) {
        super.init(frame: frame)
        contentView.translatesAutoresizingMaskIntoConstraints = false
    }

    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
        contentView.translatesAutoresizingMaskIntoConstraints = false
    }

    override func systemLayoutSizeFitting(
        _ targetSize: CGSize, withHorizontalFittingPriority
        horizontalFittingPriority: UILayoutPriority,
        verticalFittingPriority: UILayoutPriority) -> CGSize {

        width.constant = targetSize.width

and then return the final size for the cell - used for (and this feels like a bug) the dimension of the cell itself, but not contentView - which is otherwise constrained to a conflicting size (hence the constraint above). To calculate the correct cell size, I use a lower priority for the dimension that I wanted to float, and I get back the height required to fit the content within the width to which I want to fix:

        let size = contentView.systemLayoutSizeFitting(
            CGSize(width: targetSize.width, height: 1),
            withHorizontalFittingPriority: .required,
            verticalFittingPriority: verticalFittingPriority)

        print("\(#function) \(#line) \(targetSize) -> \(size)")
        return size
    }

    lazy var width: NSLayoutConstraint = {
        return contentView.widthAnchor
            .constraint(equalToConstant: bounds.size.width)
            .isActive(true)
    }()
}

But where does this width come from? It is configured via the estimatedItemSize on the collection view's flow layout:

lazy var collectionView: UICollectionView = {
    let view = UICollectionView(frame: CGRect(), collectionViewLayout: layout)
    view.backgroundColor = .cyan
    view.translatesAutoresizingMaskIntoConstraints = false
    return view
}()

lazy var layout: UICollectionViewFlowLayout = {
    let layout = UICollectionViewFlowLayout()
    let width = view.bounds.size.width // should adjust for inset
    layout.estimatedItemSize = CGSize(width: width, height: 10)
    layout.scrollDirection = .vertical
    return layout
}()

Finally, to handle rotation, I implement trailCollectionDidChange to invalidate the layout:

override func traitCollectionDidChange(_ previousTraitCollection: UITraitCollection?) {
    layout.estimatedItemSize = CGSize(width: view.bounds.size.width, height: 10)
    layout.invalidateLayout()
    super.traitCollectionDidChange(previousTraitCollection)
}

The final result looks like this:

And I have published a working sample here.

Ok so the proposed answers did'nt worked for me because I wanted to scroll by sections instead, and thus, have variable width page sizes

I did this (vertical only):

   var pagesSizes = [CGSize]()
   func scrollViewDidScroll(_ scrollView: UIScrollView) {
        defer {
            lastOffsetY = scrollView.contentOffset.y
        }
        if collectionView.isDecelerating {
            var currentPage = 0
            var currentPageBottom = CGFloat(0)
            for pagesSize in pagesSizes {
                currentPageBottom += pagesSize.height
                if currentPageBottom > collectionView!.contentOffset.y {
                    break
                }
                currentPage += 1
            }
            if collectionView.contentOffset.y > currentPageBottom - pagesSizes[currentPage].height, collectionView.contentOffset.y + collectionView.frame.height < currentPageBottom {
                return // 100% of view within bounds
            }
            if lastOffsetY < collectionView.contentOffset.y {
                if currentPage + 1 != pagesSizes.count {
                    collectionView.setContentOffset(CGPoint(x: 0, y: currentPageBottom), animated: true)
                }
            } else {
                collectionView.setContentOffset(CGPoint(x: 0, y: currentPageBottom - pagesSizes[currentPage].height), animated: true)
            }
        }
    }

In this case, I calculate each page size beforehand using the section height + header + footer, and store it in the array. That's the pagesSizes member

Just for fun, another approach would be to just leave the paging and horizontal scrolling set, add a method that changes the order of the array items to convert from 'top to bottom, left to right' to visually 'left to right, top to bottom' and fill the in-between cells with empty hidden cells to make the spacing right. In case of 7 items in a grid of 9, this would go like this:

[1][4][7]
[2][5][ ]
[3][6][ ]

should become

[1][2][3]
[4][5][6]
[7][ ][ ]

so 1=1, 2=4, 3=7 etc. and 6=empty. You can reorder them by calculating the total number of rows and columns, then calculate the row and column number for each cell, change the row for the column and vice versa and then you have the new indexes. When the cell doesn't have a value corresponding to the image you can return an empty cell and set cell.hidden = YES; to it.

It works quite well in a soundboard app I built, so if anyone would like working code I'll add it. Only little code is required to make this trick work, it sounds harder than it is!

Update

I doubt this is the best solution, but by request here's working code:

- (void)viewDidLoad {
    // Fill an `NSArray` with items in normal order
    items = [NSMutableArray arrayWithObjects:
             [NSDictionary dictionaryWithObjectsAndKeys:@"Some label 1", @"label", @"Some value 1", @"value", nil],
             [NSDictionary dictionaryWithObjectsAndKeys:@"Some label 2", @"label", @"Some value 2", @"value", nil],
             [NSDictionary dictionaryWithObjectsAndKeys:@"Some label 3", @"label", @"Some value 3", @"value", nil],
             [NSDictionary dictionaryWithObjectsAndKeys:@"Some label 4", @"label", @"Some value 4", @"value", nil],
             [NSDictionary dictionaryWithObjectsAndKeys:@"Some label 5", @"label", @"Some value 5", @"value", nil],
              nil
              ];

    // Calculate number of rows and columns based on width and height of the `UICollectionView` and individual cells (you might have to add margins to the equation based on your setup!)
    CGFloat w = myCollectionView.frame.size.width;
    CGFloat h = myCollectionView.frame.size.height;
    rows = floor(h / cellHeight);
    columns = floor(w / cellWidth);
}

// Calculate number of sections
- (NSInteger)numberOfSectionsInCollectionView:(UICollectionView *)collectionView {
    return ceil((float)items.count / (float)(rows * columns));
}

// Every section has to have every cell filled, as we need to add empty cells as well to correct the spacing
- (NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section {
    return rows*columns;
}

// And now the most important one
- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath {
    UICollectionViewCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier@"myIdentifier" forIndexPath:indexPath];

    // Convert rows and columns
    int row = indexPath.row % rows;
    int col = floor(indexPath.row / rows);
    // Calculate the new index in the `NSArray`
    int newIndex = ((int)indexPath.section * rows * columns) + col + row * columns;

    // If the newIndex is within the range of the items array we show the cell, if not we hide it
    if(newIndex < items.count) {
        NSDictionary *item = [items objectAtIndex:newIndex];
        cell.label.text = [item objectForKey:@"label"];
        cell.hidden = NO;
    } else {
        cell.hidden = YES;
    }

    return cell;
}

If you'd like to use the didSelectItemAtIndexPath method you have to use the same conversion that is used in cellForItemAtIndexPath to get the corresponding item. If you have cell margins you need to add them to the rows and columns calculation, as those have to be correct in order for this to work.

Swift 5:

func scrollViewDidEndDecelerating(_ scrollView: UIScrollView) {
    var visibleRect = CGRect()

    visibleRect.origin = collectionView.contentOffset
    visibleRect.size = collectionView.bounds.size

    let visiblePoint = CGPoint(x: visibleRect.midX, y: visibleRect.midY)

    guard let indexPath = collectionView.indexPathForItem(at: visiblePoint) else { return } 

    print(indexPath)
}

Working Answers Combined In Swift 2.2 :

 func scrollViewDidEndDecelerating(scrollView: UIScrollView) {

        var visibleRect = CGRect()

        visibleRect.origin = self.collectionView.contentOffset
        visibleRect.size = self.collectionView.bounds.size

        let visiblePoint = CGPointMake(CGRectGetMidX(visibleRect), CGRectGetMidY(visibleRect))

        let visibleIndexPath: NSIndexPath = self.collectionView.indexPathForItemAtPoint(visiblePoint)

        guard let indexPath = visibleIndexPath else { return } 
        print(indexPath)

    }

Just to correct some wrong information in this page:

1- minimumInteritemSpacing: The minimum spacing to use between items in the same row.

The default value: 10.0.

(For a vertically scrolling grid, this value represents the minimum spacing between items in the same row.)

2- minimumLineSpacing : The minimum spacing to use between lines of items in the grid.

assuming that string1 is your whole operation

use mdas

double result;
string recurAndCheck(string operation){
  if(operation.indexOf("/")){
     String leftSide = recurAndCheck(operation.split("/")[0]);
     string rightSide = recurAndCheck(operation.split("/")[1]);
     result = Double.parseDouble(leftSide)/Double.parseDouble(rightSide);

  } else if (..continue w/ *...) {
    //same as above but change / with *
  } else if (..continue w/ -) { 
    //change as above but change with -
  } else if (..continuew with +) {
    //change with add
  } else {
    return;
  }
}

I'm guessing public Method AddMethod(string aName) is defined on a public interface that FBlock implements. Consumers of that interface are not guaranteed to have access to Method.

In Android Studio, go to inside app folder, and open build.gradle file. Here you will see dependencies{}. Inside it you can add the library project and synchronise. Now after synchronising the library it will be added to your project, and you can use its functions and classes in your project.

Other answers create a new copy of the array, if you want to modify the array in place you can use:

arr.splice(_.findIndex(arr, { id: 3 }), 1);

But that assumes that the element will always be found inside the array (because if is not found it will still remove the last element). To be safe you can use:

var index = _.findIndex(arr, { id: 3 });
if (index > -1) {
    arr.splice(index, 1);
}

Alternatively, you could create a regular Mac OS X application from your script using Platypus

Using 1=1 is actually not a very good idea as this can cause full table scans by itself.

See this--> T-SQL 1=1 Performance Hit

The following works perfectly for me:

img{
   height: 99999px;
   object-fit:contain;
   max-height: 100%;
   max-width: 100%;    
   display: block;
   margin: auto auto;
}

Your declaration is int ttTreeInsert(int value);

However, your definition/implementation is

ttTree::ttTreeInsert(int value)
{
}

Notice that the return type int is missing in the implementation. Instead it should be

int ttTree::ttTreeInsert(int value)
{
    return 1; // or some valid int
}

Raising an event when a property changes is precisely what INotifyPropertyChanged does. There's one required member to implement INotifyPropertyChanged and that is the PropertyChanged event. Anything you implemented yourself would probably be identical to that implementation, so there's no advantage to not using it.

First of all, move all your PHP code to the top. Without it, my code below wont work.

To do the redirect, use:

header('Location: http://www.example.com/');

Also, please consider my advice. Since it's not the first question today and all your questions are related to basics, you should consider reading some good PHP book to understand how things work.

Here you can find useful links to free books: https://stackoverflow.com/tags/php/info

If anyone coming here because of getting this error while running a google app engine Python 3.7 standard environment project in PyCharm then all you need to do is

• Make sure the configuration to run is for Flask, not Google App Engine configuration.
• Then disable Google App Engine support under Preferences >> Languages & Framework >> Google App Engine

The reason being as per this link

The overall goal is that your app should be fully portable and run in any standard Python environment. You write a standard Python app, not an App Engine Python app. As part of this shift, you are no longer required to use proprietary App Engine APIs and services for your app's core functionality. At this time, App Engine APIs are not available in the Python 3.7 runtime.

I guess when we create a python 3.7 project in PyCharm as a Google app engine project it still tries to do the same way it does for a python2.7 app

There are now multiple ways to mimic this same effect but further tailor the properties based on the use case. As stated above, this works:

.product__specfield_8_arrow { display: inline-block } 

but also

.product__specfield_8_arrow { display: inline-flex } // flex container will be inline
.product__specfield_8_arrow { display: inline-grid } // grid container will be inline
.product__specfield_8_arrow { display: inline-table } // table will be inline-level table

This JSFiddle shows how similar these display properties are in this case.

For a relevant discussion please see this SO post.

As specified by the top answer, I used the following in the code behind the button control.

Private Sub btnClose_Click()
    Unload Me
End Sub

In doing so, it will not attempt to unload a control, but rather will unload the user form where the button control resides. The "Me" keyword refers to the user form object even when called from a control on the user form. If you are getting errors with this technique, there are a couple of possible reasons.

1. You could be entering the code in the wrong place (such as a separate module)

2. You might be using an older version of Office. I'm using Office 2013. I've noticed that VBA changes over time.

From my experience, the use of the the DoCmd.... method is more specific to the macro features in MS Access, but not commonly used in Excel VBA.

Under normal (out of the box) conditions, the code above should work just fine.

Speaking about DP solution, I found it surprising that no one mentioned the fact that LIS can be reduced to LCS. All you need to do is sort the copy of the original sequence, remove all the duplicates and do LCS of them. In pseudocode it is:

def LIS(S):
    T = sort(S)
    T = removeDuplicates(T)
    return LCS(S, T)

And the full implementation written in Go. You do not need to maintain the whole n^2 DP matrix if you do not need to reconstruct the solution.

func lcs(arr1 []int) int {
    arr2 := make([]int, len(arr1))
    for i, v := range arr1 {
        arr2[i] = v
    }
    sort.Ints(arr1)
    arr3 := []int{}
    prev := arr1[0] - 1
    for _, v := range arr1 {
        if v != prev {
            prev = v
            arr3 = append(arr3, v)
        }
    }

    n1, n2 := len(arr1), len(arr3)

    M := make([][]int, n2 + 1)
    e := make([]int, (n1 + 1) * (n2 + 1))
    for i := range M {
        M[i] = e[i * (n1 + 1):(i + 1) * (n1 + 1)]
    }

    for i := 1; i <= n2; i++ {
        for j := 1; j <= n1; j++ {
            if arr2[j - 1] == arr3[i - 1] {
                M[i][j] = M[i - 1][j - 1] + 1
            } else if M[i - 1][j] > M[i][j - 1] {
                M[i][j] = M[i - 1][j]
            } else {
                M[i][j] = M[i][j - 1]
            }
        }
    }

    return M[n2][n1]
}

If you're open to using a 3rd party library, check out javaxt-core. The javaxt.io.Directory class can be used to copy directories like this:

javaxt.io.Directory input = new javaxt.io.Directory("/source");
javaxt.io.Directory output = new javaxt.io.Directory("/destination");
input.copyTo(output, true); //true to overwrite any existing files

You can also provide a file filter to specify which files you want to copy. There are more examples here:

http://javaxt.com/javaxt-core/io/Directory/Directory_Copy

Simply return it:

<html>
    <?php
        $num = 1;
        echo $num;
    ?>
    <input type="button"
       name="lol" 
       value="Click to increment"
       onclick="Inc()" />
    <br>
    <script>
        function Inc()
        {
            Return <?php
            $num = 2;
            echo $num;
            ?>;
        }
    </script>
</html>

More generally, under most circumstances, underscore functions that take a list and argument as the first two arguments, provide access to the list index as the next to last argument to the iterator. This is an important distinction when it comes to the two underscore functions, _.reduce and _.reduceRight, that take 'memo' as their third argument -- in the case of these two the index will not be the second argument, but the third:

var destination = (function() {
    var fields = ['_333st', 'offroad', 'fbi'];
    return _.reduce(waybillInfo.destination.split(','), function(destination, segment, index) {
        destination[fields[index]] = segment;
        return destination;
    }, {});
})();

console.log(destination);            
/*
_333st: "NYARFTW  TX"
fbi: "FTWUP"
offroad: "UP"

The following is better of course but not demonstrate my point:
var destination = _.object(['_333st', 'offroad', 'fbi'], waybillInfo.destination.split(','));
*/

So if you wanted you could get the index using underscore itself: _.last(_.initial(arguments)). A possible exception (I haven't tried) is _.map, as it can take an object instead of a list: "If list is a JavaScript object, iterator's arguments will be (value, key, list)." -- see: http://underscorejs.org/#map

I can't disagree with the spirit of the accepted answer strongly enough. "A tool of last resort"? Far from it!

The way I see it, one of the strongest features of C++ compared to C and to some other similar languages is the ability to express constraints so that they can be checked at compile time and accidental misuse can be prevented. So when designing a structure, ask yourself what operations it should permit. All the other uses should be forbidden, and it's best if such restrictions can be implemented statically (at compile time) so that misuse results in a compilation failure.

So when one needs an array, the answers to the following questions specify its behavior: 1. Is its size a) dynamic at runtime, or b) static, but only known at runtime, or c) static and known at compile time? 2. Can the array be allocated on the stack or not?

And based on the answers, this is what I see as the best data structure for such an array:

       Dynamic     |   Runtime static   |         Static
Stack std::vector      unique_ptr<T[]>          std::array
Heap  std::vector      unique_ptr<T[]>     unique_ptr<std::array>

Yep, I think unique_ptr<std::array> should also be considered, and neither is a tool of last resort. Just think what fits best with your algorithm.

All of these are compatible with plain C APIs via the raw pointer to data array (vector.data() / array.data() / uniquePtr.get()).

P. S. Apart from the above considerations, there's also one of ownership: std::array and std::vector have value semantics (have native support for copying and passing by value), while unique_ptr<T[]> can only be moved (enforces single ownership). Either can be useful in different scenarios. On the contrary, plain static arrays (int[N]) and plain dynamic arrays (new int[10]) offer neither and thus should be avoided if possible - which should be possible in the vast majority of cases. If that wasn't enough, plain dynamic arrays also offer no way to query their size - extra opportunity for memory corruptions and security holes.

For some reason the above accepted answer does not work in New versions of Angular (V6).

for that use this..

async delay(ms: number) {
    await new Promise(resolve => setTimeout(()=>resolve(), ms)).then(()=>console.log("fired"));
}

above worked for me.

Usage:

this.delay(3000);

OR more accurate way

this.delay(3000).then(any=>{
     //your task after delay.
});

The problem with both iDevlop's and Ashok's answers is that the fundamental problem is an Excel design flaw (apparently) in which the Open method fails to respect the Application.ScreenUpdating setting of False. Consequently, setting it to False is of no benefit to this problem.

If Patrick McDonald's solution is too burdensome due to the overhead of starting a second instance of Excel, then the best solution I've found is to minimize the time that the opened workbook is visible by re-activating the original window as quickly as possible:

Dim TempWkBk As Workbook
Dim CurrentWin As Window

Set CurrentWin = ActiveWindow
Set TempWkBk = Workbooks.Open(SomeFilePath)
CurrentWin.Activate      'Allows only a VERY brief flash of the opened workbook
TempWkBk.Windows(1).Visible = False 'Only necessary if you also need to prevent
                                    'the user from manually accessing the opened
                                    'workbook before it is closed.

'Operate on the new workbook, which is not visible to the user, then close it...

To get all objects in a dictionary, you can also use enumerateKeysAndObjectsUsingBlock: like so:

NSMutableArray *yourArray = [NSMutableArray arrayWithCapacity:6];
[yourDict enumerateKeysAndObjectsUsingBlock:^(id key, id obj, BOOL *stop) {
    [yourArray addObject:obj];
}];

I feel like $all would be more appropriate in this situation. If you are looking for person that is into sushi you do :

PersonModel.find({ favoriteFood : { $all : ["sushi"] }, ...})

As you might want to filter more your search, like so :

PersonModel.find({ favoriteFood : { $all : ["sushi", "bananas"] }, ...})

$in is like OR and $all like AND. Check this : https://docs.mongodb.com/manual/reference/operator/query/all/

As mentioned already primitives can not be set to the Object type null.

What I do in such cases is just to use -1 or Long.MIN_VALUE.

In spark 2.2 there are two ways to add constant value in a column in DataFrame:

1) Using lit

2) Using typedLit.

The difference between the two is that typedLit can also handle parameterized scala types e.g. List, Seq, and Map

Sample DataFrame:

val df = spark.createDataFrame(Seq((0,"a"),(1,"b"),(2,"c"))).toDF("id", "col1")

+---+----+
| id|col1|
+---+----+
|  0|   a|
|  1|   b|
+---+----+

1) Using lit: Adding constant string value in new column named newcol:

import org.apache.spark.sql.functions.lit
val newdf = df.withColumn("newcol",lit("myval"))

Result:

+---+----+------+
| id|col1|newcol|
+---+----+------+
|  0|   a| myval|
|  1|   b| myval|
+---+----+------+

2) Using typedLit:

import org.apache.spark.sql.functions.typedLit
df.withColumn("newcol", typedLit(("sample", 10, .044)))

Result:

+---+----+-----------------+
| id|col1|           newcol|
+---+----+-----------------+
|  0|   a|[sample,10,0.044]|
|  1|   b|[sample,10,0.044]|
|  2|   c|[sample,10,0.044]|
+---+----+-----------------+

I have seen this issue when creating scripts in Windows env and then porting over to run on a Unix environment.

Try running dos2unix on the script:

http://dos2unix.sourceforge.net/

Or just rewrite the script in your Unix env using vi and test.

Unix uses different line endings so can't read the file you created on Windows. Hence it is seeing ^M as an illegal character.

If you want to write a file on Windows and then port over, make sure your editor is set to create files in UNIX format.

In notepad++ in the bottom right of the screen, it tells you the document format. By default, it will say Dos\Windows. To change it go to

• settings->preferences
• new document / default directory tab
• select the format as unix and close
• create a new document

The traditional way to do this is to use the Flags attribute on an enum:

[Flags]
public enum Names
{
    None = 0,
    Susan = 1,
    Bob = 2,
    Karen = 4
}

Then you'd check for a particular name as follows:

Names names = Names.Susan | Names.Bob;

// evaluates to true
bool susanIsIncluded = (names & Names.Susan) != Names.None;

// evaluates to false
bool karenIsIncluded = (names & Names.Karen) != Names.None;

Logical bitwise combinations can be tough to remember, so I make life easier on myself with a FlagsHelper class*:

// The casts to object in the below code are an unfortunate necessity due to
// C#'s restriction against a where T : Enum constraint. (There are ways around
// this, but they're outside the scope of this simple illustration.)
public static class FlagsHelper
{
    public static bool IsSet<T>(T flags, T flag) where T : struct
    {
        int flagsValue = (int)(object)flags;
        int flagValue = (int)(object)flag;

        return (flagsValue & flagValue) != 0;
    }

    public static void Set<T>(ref T flags, T flag) where T : struct
    {
        int flagsValue = (int)(object)flags;
        int flagValue = (int)(object)flag;

        flags = (T)(object)(flagsValue | flagValue);
    }

    public static void Unset<T>(ref T flags, T flag) where T : struct
    {
        int flagsValue = (int)(object)flags;
        int flagValue = (int)(object)flag;

        flags = (T)(object)(flagsValue & (~flagValue));
    }
}

This would allow me to rewrite the above code as:

Names names = Names.Susan | Names.Bob;

bool susanIsIncluded = FlagsHelper.IsSet(names, Names.Susan);

bool karenIsIncluded = FlagsHelper.IsSet(names, Names.Karen);

Note I could also add Karen to the set by doing this:

FlagsHelper.Set(ref names, Names.Karen);

And I could remove Susan in a similar way:

FlagsHelper.Unset(ref names, Names.Susan);

_{*As Porges pointed out, an equivalent of the IsSet method above already exists in .NET 4.0: Enum.HasFlag. The Set and Unset methods don't appear to have equivalents, though; so I'd still say this class has some merit.}

Note: Using enums is just the conventional way of tackling this problem. You can totally translate all of the above code to use ints instead and it'll work just as well.

The only thing that has worked for me (probably because I had inconsistencies with www. usage):

By using sscanf we can convert string to float.

#include<stdio.h>    
#include<string.h>    

int main() 
{
    char str[100] ="4.0800" ;     
    const char s[2] = "-";   
    char *token;
    double x;
   /* get the first token */ 
   token = strtok(str, s);
   sscanf(token,"%f",&x);
    printf( " %f",x );

    return 0; 
}

Best is to just Apply margin-top: 2px on the input element.

Bootstrap adds a margin-top: 4px to input element causing radio button to move down than the content.

Here is the correct way:

import MySQLdb

if __name__ == '__main__':
    connect = MySQLdb.connect(host="localhost", port=3306,
                              user="xxx", passwd="xxx", db='xxx', charset='utf8')

    cursor = connect.cursor()

    cursor.execute("""
       UPDATE tblTableName
       SET Year=%s, Month=%s, Day=%s, Hour=%s, Minute=%s
       WHERE Server=%s
    """, (Year, Month, Day, Hour, Minute, ServerID))

    connect.commit()
    connect.close()

P.S. Don't forget connect.commit(), or it won't work

Without Regex, using string comparison type:

string search = "123aa456AA789bb9991AACAA";
string pattern = "AA";
Enumerable.Range(0, search.Length)
   .Select(index => { return new { Index = index, Length = (index + pattern.Length) > search.Length ? search.Length - index : pattern.Length }; })
   .Where(searchbit => searchbit.Length == pattern.Length && pattern.Equals(search.Substring(searchbit.Index, searchbit.Length),StringComparison.OrdinalIgnoreCase))
   .Select(searchbit => searchbit.Index)

This returns {3,8,19,22}. Empty pattern would match all positions.

For multiple patterns:

string search = "123aa456AA789bb9991AACAA";
string[] patterns = new string[] { "aa", "99" };
patterns.SelectMany(pattern => Enumerable.Range(0, search.Length)
   .Select(index => { return new { Index = index, Length = (index + pattern.Length) > search.Length ? search.Length - index : pattern.Length }; })
   .Where(searchbit => searchbit.Length == pattern.Length && pattern.Equals(search.Substring(searchbit.Index, searchbit.Length), StringComparison.OrdinalIgnoreCase))
   .Select(searchbit => searchbit.Index))

This returns {3, 8, 19, 22, 15, 16}

I had the same issue with Excel, I was trying to use a 32 COM DLL with an Excel 64 bits version and I got this error. I rebuild the COM dll to a 64 bits version and the error disappears. So be sure that your COM dll has the same architecture (x86 vs x64) than your application.

If you're looking for a solution that seems to be more "by the book" and methodologically designed (using a BroadcastReceiver), you better have a look at the following link: http://www.hrupin.com/2011/10/how-to-finish-all-activities-in-your-android-application-through-simple-call.

A slight change is required in the proposed implementation that appears in that link - you should use the sendStickyBroadcast(Intent) method (don't forget to add the BROADCAST_STICKY permission to your manifest) rather than sendBroadcast(Intent), in order to enable your paused activities to be able to receive the broadcast and process it, and this means that you should also remove that sticky broadcast while restarting your application by calling the removeStickyBroadcast(Intent) method in your opening Activity's onCreate() method.

Although the above mentioned startActivity(...) based solutions, at first glance - seem to be very nice, elegant, short, fast and easy to implement - they feel a bit "wrong" (to start an activity - with all the possible overhead and resources that may be required and involved in it, just in order to kill it?...)

I'm rather shocked that this has not been answered since the solution is very simple.

As mentioned in previous posts, you would not want to convert it using C#, but just once. This is easy to do with PuTTYGen.

1. Download your .pem from AWS
2. Open PuTTYgen
3. Click "Load" on the right side about 3/4 down
4. Set the file type to *.*
5. Browse to, and Open your .pem file
6. PuTTY will auto-detect everything it needs, and you just need to click "Save private key" and you can save your ppk key for use with PuTTY

Enjoy!

How about this? Assuming SQL Server 2008:

SELECT CAST(StartDate as date) AS ForDate,
       DATEPART(hour,StartDate) AS OnHour,
       COUNT(*) AS Totals
FROM #Events
GROUP BY CAST(StartDate as date),
       DATEPART(hour,StartDate)

For pre-2008:

SELECT DATEADD(day,datediff(day,0,StartDate),0)   AS ForDate,
       DATEPART(hour,StartDate) AS OnHour,
       COUNT(*) AS Totals
FROM #Events
GROUP BY CAST(StartDate as date),
       DATEPART(hour,StartDate)

This results in :

ForDate                 | OnHour | Totals

Sybase has the same case syntax as SQL Server:

Description

Supports conditional SQL expressions; can be used anywhere a value expression can be used.

Syntax

case 
     when search_condition then expression 
    [when search_condition then expression]...
    [else expression]
end

Case and values syntax

case expression
     when expression then expression 
    [when expression then expression]...
    [else expression]
end

Parameters

case

begins the case expression.

when

precedes the search condition or the expression to be compared.

search_condition

is used to set conditions for the results that are selected. Search conditions for case expressions are similar to the search conditions in a where clause. Search conditions are detailed in the Transact-SQL User’s Guide.

then

precedes the expression that specifies a result value of case.

expression

is a column name, a constant, a function, a subquery, or any combination of column names, constants, and functions connected by arithmetic or bitwise operators. For more information about expressions, see “Expressions” in.

Example

select disaster, 
       case
            when disaster = "earthquake" 
                then "stand in doorway"
            when disaster = "nuclear apocalypse" 
                then "hide in basement"
            when monster = "zombie apocalypse" 
                then "hide with Chuck Norris"
            else
                then "ask mom"
       end 
  from endoftheworld

You could use @> operator to do this something like

SELECT info->>'name'
FROM rabbits
WHERE info->'food' @> '"carrots"';

you can put div tags inside a td tag, but not directly inside a table or tr tag. examples:

this works:

<table>_x000D_
  <tr>_x000D_
    <td> _x000D_
      <div>This will work.</div> _x000D_
    </td>_x000D_
  </tr>_x000D_
<table>

this does not work:

<table>_x000D_
  <tr>_x000D_
    <div> this does not work. </div> _x000D_
  </tr>_x000D_
</table>

nor does this work:

<table>_x000D_
  <div> this does not work. </div>_x000D_
</table>

This problem was due to the use of AngularJS 1.1.5 (which was unstable, and obviously had some bug or different implementation of the routing than it was in 1.0.7)

turning it back to 1.0.7 solved the problem instantly.

have tried the 1.2.0rc1 version, but have not finished testing as I had to rewrite some of the router functionality since they took it out of the core.

anyway, this problem is fixed when using AngularJS vs 1.0.7.

You can use jQuery's getJSON() or Load(); with the latter, you can reference an existing html file. For more details, see http://www.codeproject.com/Articles/661782/Three-Ways-to-Dynamically-Load-HTML-Content-into-a

MyList.OrderBy(x => x.StartDate).ThenByDescending(x => x.EndDate);

Note that you can use as well the Descending keyword in the OrderBy (in case you need). So another possible answer is:

MyList.OrderByDescending(x => x.StartDate).ThenByDescending(x => x.EndDate);

Excellent!

I share with you, code from a function that compares passwords:

SET pSignal =
(SELECT DECODE(r.usignal,'YOURSTRINGKEY') FROM rsw_uds r WHERE r.uname =
in_usdname AND r.uvige = 1);

SET pSuccess =(SELECT in_usdsignal LIKE BINARY pSignal);

IF pSuccess = 1 THEN
      /*Your code if match*/
ELSE
      /*Your code if don't match*/

END IF;

I had this problem for a long while and I couldn't figure out the answer. I had added all the paths, built everything and pretty much followed what everyone on here had suggested, but no luck.

Finally I read the comments and saw that there were some compilation errors that were aborting the procedure before the binaries and exe file was generated.

Bottom line: Do a code review and make sure that there are no errors in your code because sometimes eclipse will not always catch everything.

If you can run a basic hello world but not your code then obviously something is wrong with your code. I learned the hard way.

Another possible way to have bootstrap icons in a different color is to create a new .png in the desired color, (eg. magenta) and save it as /path-to-bootstrap-css/img/glyphicons-halflings-magenta.png

In your variables.less find

// Sprite icons path
// -------------------------
@iconSpritePath:          "../img/glyphicons-halflings.png";
@iconWhiteSpritePath:     "../img/glyphicons-halflings-white.png";

and add this line

@iconMagentaSpritePath:     "../img/glyphicons-halflings-magenta.png";

In your sprites.less add

/* Magenta icons with optional class, or on hover/active states of certain elements */
.icon-magenta,
.nav-pills > .active > a > [class^="icon-"],
.nav-pills > .active > a > [class*=" icon-"],
.nav-list > .active > a > [class^="icon-"],
.nav-list > .active > a > [class*=" icon-"],
.navbar-inverse .nav > .active > a > [class^="icon-"],
.navbar-inverse .nav > .active > a > [class*=" icon-"],
.dropdown-menu > li > a:hover > [class^="icon-"],
.dropdown-menu > li > a:hover > [class*=" icon-"],
.dropdown-menu > .active > a > [class^="icon-"],
.dropdown-menu > .active > a > [class*=" icon-"],
.dropdown-submenu:hover > a > [class^="icon-"],
.dropdown-submenu:hover > a > [class*=" icon-"] {
  background-image: url("@{iconMagentaSpritePath}");
}

And use it like this:

<i class='icon-chevron-down icon-magenta'></i>

Hope it helps someone.

On the server.. In our environment, we're running Apache2 on Windows Server 2003.
Suppose Apache is serving our repository from C:\repo\MyProject

The actual repository is in C:\repo\MyProject\db

and the configuration is in C:\repo\MyProject\conf

So the passwords are in: C:\repo\MyProject.htaccess

They're encrypted, a tool similar to this: http://tools.dynamicdrive.com/password/

TOP (100) PERCENT is completely meaningless in recent versions of SQL Server, and it (along with the corresponding ORDER BY, in the case of a view definition or derived table) is ignored by the query processor.

You're correct that once upon a time, it could be used as a trick, but even then it wasn't reliable. Sadly, some of Microsoft's graphical tools put this meaningless clause in.

As for why this might appear in dynamic SQL, I have no idea. You're correct that there's no reason for it, and the result is the same without it (and again, in the case of a view definition or derived table, without both the TOP and ORDER BY clauses).

With EF or LINQ to SQL:

var item = db.Items.OrderByDescending(i => i.Value).FirstOrDefault();

With LINQ to Objects I suggest to use morelinq extension MaxBy (get morelinq from nuget):

var item = items.MaxBy(i => i.Value);

If memory serves correct, the reg add command will NOT create the entire directory path if it does not exist. Meaning that if any of the parent registry keys do not exist then they must be created manually one by one. It is really annoying, I know! Example:

@echo off
reg add "HKCU\Software\Policies"
reg add "HKCU\Software\Policies\Microsoft"
reg add "HKCU\Software\Policies\Microsoft\Internet Explorer"
reg add "HKCU\Software\Policies\Microsoft\Internet Explorer\Control Panel"
reg add "HKCU\Software\Policies\Microsoft\Internet Explorer\Control Panel" /v HomePage /t REG_DWORD /d 1 /f

Here's a variation of @RichieHindle's excellent answer which implements a decorator that can be selectively applied to functions as desired. Works with Python 2.7.14 and 3.6.4.

from __future__ import print_function
import functools
import traceback
import sys

INDENT = 4*' '

def stacktrace(func):
    @functools.wraps(func)
    def wrapped(*args, **kwds):
        # Get all but last line returned by traceback.format_stack()
        # which is the line below.
        callstack = '\n'.join([INDENT+line.strip() for line in traceback.format_stack()][:-1])
        print('{}() called:'.format(func.__name__))
        print(callstack)
        return func(*args, **kwds)

    return wrapped

@stacktrace
def test_func():
    return 42

print(test_func())

Output from sample:

test_func() called:
    File "stacktrace_decorator.py", line 28, in <module>
    print(test_func())
42

Just for fun:

var mystring = "this,is,a,test"  
var newchar = '|'
mystring = mystring.split(',').join(newchar);

Make the DropDownStyle to DropDownList

stateComboBox.DropDownStyle = ComboBoxStyle.DropDownList;

This is good in the general case:

yourPath.Split(@"\/", StringSplitOptions.RemoveEmptyEntries)

There is no empty element in the returned array if the path itself ends in a (back)slash (e.g. "\foo\bar\"). However, you will have to be sure that yourPath is really a directory and not a file. You can find out what it is and compensate if it is a file like this:

if(Directory.Exists(yourPath)) {
  var entries = yourPath.Split(@"\/", StringSplitOptions.RemoveEmptyEntries);
}
else if(File.Exists(yourPath)) {
  var entries = Path.GetDirectoryName(yourPath).Split(
                    @"\/", StringSplitOptions.RemoveEmptyEntries);
}
else {
  // error handling
}

I believe this covers all bases without being too pedantic. It will return a string[] that you can iterate over with foreach to get each directory in turn.

If you want to use constants instead of the @"\/" magic string, you need to use

var separators = new char[] {
  Path.DirectorySeparatorChar,  
  Path.AltDirectorySeparatorChar  
};

and then use separators instead of @"\/" in the code above. Personally, I find this too verbose and would most likely not do it.

You are using an adjacent sibling selector (+) when the elements are not siblings. The label is the parent of the input, not it's sibling.

CSS has no way to select an element based on it's descendents (nor anything that follows it).

You'll need to look to JavaScript to solve this.

Alternatively, rearrange your markup:

<input id="foo"><label for="foo">…</label>

Edited:

You should really be using openssl_encrypt() & openssl_decrypt()

As Scott says, Mcrypt is not a good idea as it has not been updated since 2007.

There is even an RFC to remove Mcrypt from PHP - https://wiki.php.net/rfc/mcrypt-viking-funeral

I solved my issue like that. You need the change auth_type 'config' to 'http'. My older settings auth_type is 'config' then i changed to 'http' and problem solved.

When you changed that area and enter the phpMyAdmin, browser asks you a user and password. You just enter 'root' and dont fill the password area and press enter.

/* Authentication type and info */
$cfg['Servers'][$i]['auth_type'] = 'http';
$cfg['Servers'][$i]['user'] = 'root';
$cfg['Servers'][$i]['password'] = '';
$cfg['Servers'][$i]['extension'] = 'mysqli';
$cfg['Servers'][$i]['AllowNoPassword'] = true;
$cfg['Lang'] = '';

I will avoid iterator as they can add/remove object during iteration, also for clean code use for loop. it will be simply clean & fewer lines.

Using Java 8 and Lamda [Update 4/2/2019]

import org.json.JSONObject;

public static void printJsonObject(JSONObject jsonObj) {
    jsonObj.keySet().forEach(keyStr ->
    {
        Object keyvalue = jsonObj.get(keyStr);
        System.out.println("key: "+ keyStr + " value: " + keyvalue);

        //for nested objects iteration if required
        //if (keyvalue instanceof JSONObject)
        //    printJsonObject((JSONObject)keyvalue);
    });
}

Using old way [Update 4/2/2019]

import org.json.JSONObject;

public static void printJsonObject(JSONObject jsonObj) {
    for (String keyStr : jsonObj.keySet()) {
        Object keyvalue = jsonObj.get(keyStr);

        //Print key and value
        System.out.println("key: "+ keyStr + " value: " + keyvalue);

        //for nested objects iteration if required
        //if (keyvalue instanceof JSONObject)
        //    printJsonObject((JSONObject)keyvalue);
    }
}

Original Answer

import org.json.simple.JSONObject;
public static void printJsonObject(JSONObject jsonObj) {
    for (Object key : jsonObj.keySet()) {
        //based on you key types
        String keyStr = (String)key;
        Object keyvalue = jsonObj.get(keyStr);

        //Print key and value
        System.out.println("key: "+ keyStr + " value: " + keyvalue);

        //for nested objects iteration if required
        if (keyvalue instanceof JSONObject)
            printJsonObject((JSONObject)keyvalue);
    }
}

Use two single-quotes

SQL> SELECT 'D''COSTA' name FROM DUAL;

NAME
-------
D'COSTA

Alternatively, use the new (10g+) quoting method:

SQL> SELECT q'$D'COSTA$' NAME FROM DUAL;

NAME
-------
D'COSTA

map<string,string>m;
auto it=m.begin();//get iterator to the first element of map(m)
return m->first;//return first string(1st string in map<string,string>m)
//Incase you want the second string 
//you can use return m->second(2st string in map<string,string>m)
//if you want to iterate the whole map you can use loop
for(auto it:m)//m is a map
   cout<<it->first<<endl;

I had a case where I knew all the numbers in question would have only one decimal and wanted to get the decimal portion as an integer so I ended up using this kind of approach:

var number = 3.1,
    decimalAsInt = Math.round((number - parseInt(number)) * 10); // returns 1

This works nicely also with integers, returning 0 in those cases.

numba

For recursive calculations which are not vectorisable, numba, which uses JIT-compilation and works with lower level objects, often yields large performance improvements. You need only define a regular for loop and use the decorator @njit or (for older versions) @jit(nopython=True):

For a reasonable size dataframe, this gives a ~30x performance improvement versus a regular for loop:

from numba import jit

@jit(nopython=True)
def calculator_nb(a, b, d):
    res = np.empty(d.shape)
    res[0] = d[0]
    for i in range(1, res.shape[0]):
        res[i] = res[i-1] * a[i] + b[i]
    return res

df['C'] = calculator_nb(*df[list('ABD')].values.T)

n = 10**5
df = pd.concat([df]*n, ignore_index=True)

# benchmarking on Python 3.6.0, Pandas 0.19.2, NumPy 1.11.3, Numba 0.30.1
# calculator() is same as calculator_nb() but without @jit decorator
%timeit calculator_nb(*df[list('ABD')].values.T)  # 14.1 ms per loop
%timeit calculator(*df[list('ABD')].values.T)     # 444 ms per loop

select count(*) 
from table_emp 
 where DATEPART(YEAR, ARR_DATE) = '2012' AND DATEPART(MONTH, ARR_DATE) = '01'

Other words printf absent in python... I'm surprised! Best code is

def printf(format, *args):
    sys.stdout.write(format % args)

Because of this form allows not to print \n. All others no. That's why print is bad operator. And also you need write args in special form. There is no disadvantages in function above. It's a standard usual form of printf function.

On laravel 5.6 it has a very simple solution:

User::where('username', $username)->first()->groupName;

It will return groupName as a string.

$headers = array(
    'Authorization: Basic '. base64_encode($username.':'.$password),
);
...
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);

Interfaces can not be directly instantiated, you should instantiate classes that implements such Interfaces.

Try this:

NameValuePair[] params = new BasicNameValuePair[] {
        new BasicNameValuePair("param1", param1),
        new BasicNameValuePair("param2", param2),
};

My solution:

First create "<style>" tags with an ID.

<style id="YourID">
    .YourClass {background-color:red}
</style>

Then, I create a function in JavaScript like this:

document.getElementById('YourID').innerHTML = '.YourClass {background-color:blue}'

Worked like a charm for me.

I was having the same problem and the post of Paolo helped me out, but I needed to adjust one thing. My form with id advancedindexsearch only contained input fields and gets the values from a session. For some reason the following did not work for me:

$("#advancedindexsearch").find("input:text").val("");

If I put an alert after this, I saw the values where removed correctly but afterwards they where replaced again. I still don't know how or why but the following line did do the trick for me:

$("#advancedindexsearch").find("input:text").attr("value","");

I and many other shave spent way too long on this - this needs a massive improvement. After spending hours, I finally copied php_pgsql.dll from php's ext directory to Apache24's root directory (wherever you installed it) and finally Apache was able to get the php/pg modules and dlls loaded.

The global update and the my.cnf settings didn't work for me for some reason. Passing the max_allowed_packet value directly to the client worked here:

mysql -h <hostname> -u username -p --max_allowed_packet=1073741824 <databasename> < db.sql

Well, I get the attr rows from the table and get the length for that collection:

$("#myTable").attr('rows').length;

I think that jQuery works less.

request.user.get_username() or request.user.username, former is preferred.

Django docs say:

Since the User model can be swapped out, you should use this method instead of referencing the username attribute directly.

P.S. For templates, use {{ user.get_username }}

Set editable to False and default to your default value.

http://docs.djangoproject.com/en/stable/ref/models/fields/#editable

b = models.CharField(max_length=7, default='0000000', editable=False)

Also, your id field is unnecessary. Django will add it automatically.

I think now Fragment nesting is available just update the back computability jar

now lets dig in the problem it self .

public void onClick2(View view) {
    Fragment2 fragment2 = new Fragment2();
    FragmentManager fragmentManager = getFragmentManager();
    FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
    fragmentTransaction.replace(R.id.fragment1, fragment2);
    fragmentTransaction.commit();
}

I think the R.id.fragment1 belongs to a TextView which is not a good place to include child views in because its not a ViewGroup, you can remove the textView from the xml and replace it with a LinearLayout lets say and it will work , if not tell me what the error .

fragment1.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#f0f0f0"
android:orientation="vertical" >

<LinearLayout 
    android:id="@+id/fragment1"
    android:layout_height="wrap_content"
    android:layout_width="fill_parent"
    />

    android:text="Call Fragment 2"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    />
</LinearLayout>

Update for the error in the comment

public class Fragment1 extends Fragment implements OnClickListener{

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View v = inflater.inflate(R.layout.fragment1, container, false);
((Button) v.findViewById(R.id.btn_frag2)).setOnClickListener(this);
    return v;
}

    FragmentManager fragmentManager = getFragmentManager();
    FragmentTransaction fragmentTransaction =        fragmentManager.beginTransaction();
    fragmentTransaction.replace(R.id.container, fragment2);
    fragmentTransaction.addToBackStack(null);
    fragmentTransaction.commit();
}

I heartily recommended dbVis. The client runs on Mac, Windows and Linux and supports a variety of database servers, including PostgreSQL.

As DotNetMensch said but you DO NOT need to add another site in IIS as this can also cause further problems and make things more complicated because you then have a website within a website so the file paths, masterpage paths and web.config paths may need changing. You just need to edit teh bindings of the existing site and add the new subdomain there.

So:

1. Add sub-domain to DNS records. My host (RackSpace) uses a web portal to do this so you just log in and go to Network->Domains(DNS)->Actions->Create Zone, and enter your subdomain as mysubdomain.domain.com etc, leave the other settings as default

2. Go to your domain in IIS, right-click->Edit Bindings->Add, and add your new subdomain leaving everything else the same e.g. mysubdomain.domain.com

You may need to wait 5-10 mins for the DNS records to update but that's all you need.

You can use a loop to check every character position and catch the IndexOutOfBoundsException when you pass the last character. But why?

public int slowLength(String myString) {
    int i = 0;
    try {
        while (true) {
            myString.charAt(i);
            i++;
        }
    } catch (IndexOutOfBoundsException e) {
       return i;
    }
}

Note: This is very bad programming practice and very inefficient.

You can use reflection to examine the internal variables in the String class, specifically count.

For those who were as confused as I was when reading the answers, in your package.json file, add "type": "module" in the upper level as show below:

{
  "name": "my-app",
  "version": "0.0.0",
  "type": "module",
  "scripts": { ...
  },
  ...
}

__stdcall is the calling convention used for the function. This tells the compiler the rules that apply for setting up the stack, pushing arguments and getting a return value.

There are a number of other calling conventions, __cdecl, __thiscall, __fastcall and the wonderfully named __declspec(naked). __stdcall is the standard calling convention for Win32 system calls.

Wikipedia covers the details.

It primarily matters when you are calling a function outside of your code (e.g. an OS API) or the OS is calling you (as is the case here with WinMain). If the compiler doesn't know the correct calling convention then you will likely get very strange crashes as the stack will not be managed correctly.

It's not easy to find a full solution of the problem of a convertion of an arbitrary HTML to PDF with non-english letters in Android. I test it for russian unicode letters.

We use three libraries:

(1) Jsoup (jsoup-1.7.3.jar) for a convertion from HTML to XHTML,

(2) iTextPDF (itextpdf-5.5.0.jar),

(3) XMLWorker (xmlworker-5.5.1.jar).

public boolean createPDF(String rawHTML, String fileName, ContextWrapper context){
    final String APPLICATION_PACKAGE_NAME = context.getBaseContext().getPackageName();
    File path = new File( Environment.getExternalStorageDirectory(), APPLICATION_PACKAGE_NAME );
    if ( !path.exists() ){ path.mkdir(); }
    File file = new File(path, fileName);

    try{

    Document document = new Document();
    PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream(file));
    document.open();

    // ?????????????? HTML
    String htmlText = Jsoup.clean( rawHTML, Whitelist.relaxed() );
    InputStream inputStream = new ByteArrayInputStream( htmlText.getBytes() );

    // ???????? ???????? PDF
    XMLWorkerHelper.getInstance().parseXHtml(writer, document,
        inputStream, null, Charset.defaultCharset(), new MyFont());

    document.close();
    return true;

    } catch (FileNotFoundException e) {
        e.printStackTrace();
        return false;
    } catch (DocumentException e) {
        e.printStackTrace();
        return false;
    } catch (IOException e) {
        e.printStackTrace();
        return false;
    } 

The difficult problem is to display russian letters in PDF by using iTextPDF XMLWorker library. For this we should create our own implementation of FontProvider interface:

public class MyFont implements FontProvider{
    private static final String FONT_PATH = "/system/fonts/DroidSans.ttf";
    private static final String FONT_ALIAS = "my_font";

    public MyFont(){ FontFactory.register(FONT_PATH, FONT_ALIAS); }

    @Override
    public Font getFont(String fontname, String encoding, boolean embedded,
        float size, int style, BaseColor color){

        return FontFactory.getFont(FONT_ALIAS, BaseFont.IDENTITY_H, 
            BaseFont.EMBEDDED, size, style, color);
    }

    @Override
    public boolean isRegistered(String name) { return name.equals( FONT_ALIAS ); }
}

Here we use the standard Android font Droid Sans, which is located in the system folder:

private static final String FONT_PATH = "/system/fonts/DroidSans.ttf";

I notice that in your first example, the simple :order => "date", record 7 is sorted before record 1. This order is also how you see the results in the multi-column sort, regardless of whether you sort by attending.

This would seem to make sense to me if the dates weren't exactly the same, and the date for 7 is before the date for 1. Instead of finding that the dates are exactly equal then proceeding to sort by attending, the query finds that the dates are not equal and simply sorts by that like all the other records.

I see from browsing around that SQLite doesn't have a native understanding of DATE or DATETIME data types and instead gives users the choice of floating point numbers or text that they must parse themselves. Is it possible that the literal representation of the dates in the database are not exactly equal? Most people seem to need to use date functions so that dates behave like you would expect. Perhaps there's a way to wrap your order by column with a date function that will give you something concrete to compare, like date(date) ASC, attending DESC. I'm not sure that syntax works, but it's an area to look at for solving your problem. Hope that helps.

Visual Studio 2013 now supports setup projects. Microsoft have shipped a Visual Studio extension to produce setup projects.

Visual Studio Installer Projects Extension

Run like:

  $ mvn help:describe -DartifactId=maven-war-plugin -DgroupId=org.apache.maven.plugins

for plug-in that have no version. You get output:

Name: Maven WAR Plugin
Description: Builds a Web Application Archive (WAR) file from the project
  output and its dependencies.
Group Id: org.apache.maven.plugins
Artifact Id: maven-war-plugin
Version: 2.2
Goal Prefix: war

Use version that shown in output.

UPDATE If you want to select among list of versions, use http://search.maven.org/ or http://mvnrepository.com/ Note that your favorite Java IDE must have Maven package search dialog. Just check docs.

SUPER UPDATE I also use:

$ mvn dependency:tree
$ mvn dependency:list
$ mvn dependency:resolve
$ mvn dependency:resolve-plugins  # <-- THIS

Recently I discover how to get latest version for plug-in (or library) so no longer needs for googling or visiting Maven Central:

$ mvn versions:display-dependency-updates
$ mvn versions:display-plugin-updates     # <-- THIS

In case you want a quicker (but still very clean) way of achieving it for a personal purpose (for instance if you want to build a specific project having some strong requirements concerning the version of the compiler), just follow the following steps:

• type echo $PATH and look for a personal directory having a very high priority (in my case, I have ~/.local/bin);
• add the symbolic links in this directory:

For instance:

ln -s /usr/bin/gcc-WHATEVER ~/.local/bin/gcc
ln -s /usr/bin/g++-WHATEVER ~/.local/bin/g++

Of course, this will work for a single user (it isn't a system wide solution), but on the other hand I don't like to change too many things in my installation.

The name open addressing refers to the fact that the location ("address") of the element is not determined by its hash value. (This method is also called closed hashing).

In separate chaining, each bucket is independent, and has some sort of ADT (list, binary search trees, etc) of entries with the same index. In a good hash table, each bucket has zero or one entries, because we need operations of order O(1) for insert, search, etc.

This is a example of separate chaining using C++ with a simple hash function using mod operator (clearly, a bad hash function)

Store.getRange() seems to be exactly what you are searching for. It will return you Ext.data.Record[] - array of records. If no arguments is passed, all the records are returned.

var maxAge = list.Max(x => x.Age);

You don't have that many options.

You'll probably want to use one of:

• node-soap
• strong-soap (rewrite of node-soap)
• easysoap

This is a Scala version that is clean and fast (no stackoverflow):

  import scala.annotation.tailrec
  import java.io._

  implicit class InputStreamOps(in: InputStream) {
    def >(out: OutputStream): Unit = pipeTo(out)

    def pipeTo(out: OutputStream, bufferSize: Int = 1<<10): Unit = pipeTo(out, Array.ofDim[Byte](bufferSize))

    @tailrec final def pipeTo(out: OutputStream, buffer: Array[Byte]): Unit = in.read(buffer) match {
      case n if n > 0 =>
        out.write(buffer, 0, n)
        pipeTo(out, buffer)
      case _ =>
        in.close()
        out.close()
    }
  }

This enables to use > symbol e.g. inputstream > outputstream and also pass in custom buffers/sizes.

You are specifying .fixedbutton in your CSS (a class) and specifying the id on the element itself.

Change your CSS to the following, which will select the id fixedbutton

#fixedbutton {
    position: fixed;
    bottom: 0px;
    right: 0px; 
}

pip install tensorflow.tensorboard  # install tensorboard
pip show tensorflow.tensorboard
# Location: c:\users\<name>\appdata\roaming\python\python35\site-packages
# now just run tensorboard as:

I have got the solution for my query:

i have done something like this:

cell.innerHTML="<img height=40 width=40 alt='' src='<%=request.getContextPath()%>/writeImage.htm?' onerror='onImgError(this);' onLoad='setDefaultImage(this);'>"

function setDefaultImage(source){
        var badImg = new Image();
        badImg.src = "video.png";
        var cpyImg = new Image();
        cpyImg.src = source.src;

        if(!cpyImg.width)
        {
            source.src = badImg.src;
        }

    }


    function onImgError(source){
        source.src = "video.png";
        source.onerror = ""; 
        return true; 
    } 

This way it's working in all browsers.

I had the same problem and tired all the above solutions and did not work for me! the problem was because multiple networks make conflict between VMware and VirtualBox, and other VPN connections. The solution i followed is:

• solution 1 :

uninstall virtualbox and reinstall the last update of it

• solution 2 :

If solution 1 not working, try this uninstalling all VPN programs, VirtualBox, Genymotion and reinstalled VirtualBox and Genymotion again. both solutions worked with me

for i in range(16):
    print datetime.date.today() + datetime.timedelta(days=i)

Events onunload or onbeforeunload you can't use directly - they do not differ between window close, page refresh, form submit, link click or url change.

The only working solution is How to capture the browser window close event?

The EntityManager.flush() operation can be used the write all changes to the database before the transaction is committed. By default JPA does not normally write changes to the database until the transaction is committed. This is normally desirable as it avoids database access, resources and locks until required. It also allows database writes to be ordered, and batched for optimal database access, and to maintain integrity constraints and avoid deadlocks. This means that when you call persist, merge, or remove the database DML INSERT, UPDATE, DELETE is not executed, until commit, or until a flush is triggered.

Since PyYAML's yaml.load() function parses YAML documents to native Python data structures, you can just access items by key or index. Using the example from the question you linked:

import yaml
with open('tree.yaml', 'r') as f:
    doc = yaml.load(f)

To access branch1 text you would use:

txt = doc["treeroot"]["branch1"]
print txt
"branch1 text"

because, in your YAML document, the value of the branch1 key is under the treeroot key.

You want reasons? Here's one:

A web form can't be used to send a request to a page that uses a mix of GET and POST. If you set the form's method to GET, all the parameters are in the query string. If you set the form's method to POST, all the parameters are in the request body.

For Bootstrap 3.1 you'll want to remove data and empty the modal-content rather than the whole dialog (3.0) to avoid the flicker while waiting for remote content to load.

$(document).on("hidden.bs.modal", function (e) {
    $(e.target).removeData("bs.modal").find(".modal-content").empty();
});

If you are using non-remote modals then the above code will, of course, remove their content once closed (bad). You may need to add something to those modals (like a .local-modal class) so they aren't affected. Then modify the above code to:

$(document).on("hidden.bs.modal", ".modal:not(.local-modal)", function (e) {
    $(e.target).removeData("bs.modal").find(".modal-content").empty();
});

Yes, there is a way to emulate max-width using a table, thus giving you both responsive and Outlook-friendly layout. What's more, this solution doesn't require conditional comments.

Suppose you want the equivalent of a centered div with max-width of 350px. You create a table, set the width to 100%. The table has three cells in a row. Set the width of the center TD to 350 (using the HTML width attribute, not CSS), and there you go.

If you want your content aligned left instead of centered, just leave out the first empty cell.

Example:

<table border="0" cellspacing="0" width="100%">
    <tr>
        <td></td>
        <td width="350">The width of this cell should be a maximum of 
                  350 pixels, but shrink to widths less than 350 pixels.
        </td>
        <td></td>
     </tr>
</table> 

In the jsfiddle I give the table a border so you can see what's going on, but obviously you wouldn't want one in real life:

_{MuSTaNG's answer says it all, but I am still adding it to make it a little more elaborate, with links and all.}

The conventional operators

• greater than (>),
• less than (<),
• equality (==),
• and more

are available for DateTime since .NET Framework 1.1. Also, addition and subtraction of DateTime objects are also possible using conventional operators + and -.

One example from MSDN:

System.DateTime april19 = new DateTime(2001, 4, 19);
System.DateTime otherDate = new DateTime(1991, 6, 5);

// areEqual gets false.
bool areEqual = april19 == otherDate;

otherDate = new DateTime(2001, 4, 19);
// areEqual gets true.
areEqual = april19 == otherDate;

Other operators can be used likewise.

Here is the list all operators available for DateTime.

I'll never easily remember these cryptic command modifiers so I took the top answer and turned it into a function in my ~/.bashrc file:

cgrep() {
    # For files that are arrays 10's of thousands of characters print.
    # Use cpgrep to print 30 characters before and after search patttern.
    if [ $# -eq 2 ] ; then
        # Format was 'cgrep "search string" /path/to/filename'
        grep -o -P ".{0,30}$1.{0,30}" "$2"
    else
        # Format was 'cat /path/to/filename | cgrep "search string"
        grep -o -P ".{0,30}$1.{0,30}"
    fi
} # cgrep()

Here's what it looks like in action:

$ ll /tmp/rick/scp.Mf7UdS/Mf7UdS.Source

-rw-r--r-- 1 rick rick 25780 Jul  3 19:05 /tmp/rick/scp.Mf7UdS/Mf7UdS.Source

$ cat /tmp/rick/scp.Mf7UdS/Mf7UdS.Source | cgrep "Link to iconic"

1:43:30.3540244000 /mnt/e/bin/Link to iconic S -rwxrwxrwx 777 rick 1000 ri

$ cgrep "Link to iconic" /tmp/rick/scp.Mf7UdS/Mf7UdS.Source

1:43:30.3540244000 /mnt/e/bin/Link to iconic S -rwxrwxrwx 777 rick 1000 ri

The file in question is one continuous 25K line and it is hopeless to find what you are looking for using regular grep.

Notice the two different ways you can call cgrep that parallels grep method.

There is a "niftier" way of creating the function where "$2" is only passed when set which would save 4 lines of code. I don't have it handy though. Something like ${parm2} $parm2. If I find it I'll revise the function and this answer.

Open res -> values -> styles.xml and to your <style> add this line replacing with your image path <item name="android:windowBackground">@drawable/background</item>. Example:

<resources>

    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
        <item name="android:windowBackground">@drawable/background</item>
    </style>

</resources>

There is a <item name ="android:colorBackground">@color/black</item> also, that will affect not only your main window background but all the component in your app. Read about customize theme here.

If you want version specific styles:

If a new version of Android adds theme attributes that you want to use, you can add them to your theme while still being compatible with old versions. All you need is another styles.xml file saved in a values directory that includes the resource version qualifier. For example:

res/values/styles.xml        # themes for all versions
res/values-v21/styles.xml    # themes for API level 21+ only

Because the styles in the values/styles.xml file are available for all versions, your themes in values-v21/styles.xml can inherit them. As such, you can avoid duplicating styles by beginning with a "base" theme and then extending it in your version-specific styles.

Read more here(doc in theme).

For an example data in your table such as combinations of

'', null and as well as actual value than if you want to only actual value and replace to '' and null value by # symbol than execute this query

SELECT Column_Name = (CASE WHEN (Column_Name IS NULL OR Column_Name = '') THEN '#' ELSE Column_Name END) FROM Table_Name

and another way you can use it but this is little bit lengthy and instead of this you can also use IsNull function but here only i am mentioning IIF function

SELECT IIF(Column_Name IS NULL, '#', Column_Name) FROM Table_Name  
SELECT IIF(Column_Name  = '', '#', Column_Name) FROM Table_Name  
-- and syntax of this query
SELECT IIF(Column_Name IS NULL, 'True Value', 'False Value') FROM Table_Name

Try:

<xsl:value-of select="count(preceding-sibling::*) + 1" />

Edit - had a brain freeze there, position() is more straightforward!

Since dates are converted to UNIX epoch (numbers), you can use Math.max/min to find those:

var maxDate = Math.max.apply(null, dates)
// convert back to date object
maxDate = new Date(maxDate)

(tested in chrome only, but should work in most browsers)

private static void SaveImage(Bitmap finalBitmap) {

    String root = Environment.getExternalStorageDirectory().getAbsolutePath();
    File myDir = new File(root + "/saved_images");
    myDir.mkdirs();

    String fname = "Image-"+ o +".jpg";
    File file = new File (myDir, fname);
    if (file.exists ()) file.delete ();
    try {
        FileOutputStream out = new FileOutputStream(file);
        finalBitmap.compress(Bitmap.CompressFormat.JPEG, 90, out);
        out.flush();
        out.close();

    } catch (Exception e) {
        e.printStackTrace();
    }
}

They find a solution suboptimally without any guarantee as to the quality of solution found, it is obvious that it makes sense to the development of heuristics only polynomial. The application of these methods is suitable to solve real world problems or large problems so awkward from the computational point of view that for them there is not even an algorithm capable of finding an approximate solution in polynomial time.

I'm writing an updated answer for Python 3 to this question.

How is __eq__ handled in Python and in what order?

a == b

It is generally understood, but not always the case, that a == b invokes a.__eq__(b), or type(a).__eq__(a, b).

Explicitly, the order of evaluation is:

1. if b's type is a strict subclass (not the same type) of a's type and has an __eq__, call it and return the value if the comparison is implemented,
2. else, if a has __eq__, call it and return it if the comparison is implemented,
3. else, see if we didn't call b's __eq__ and it has it, then call and return it if the comparison is implemented,
4. else, finally, do the comparison for identity, the same comparison as is.

We know if a comparison isn't implemented if the method returns NotImplemented.

(In Python 2, there was a __cmp__ method that was looked for, but it was deprecated and removed in Python 3.)

Let's test the first check's behavior for ourselves by letting B subclass A, which shows that the accepted answer is wrong on this count:

class A:
    value = 3
    def __eq__(self, other):
        print('A __eq__ called')
        return self.value == other.value

class B(A):
    value = 4
    def __eq__(self, other):
        print('B __eq__ called')
        return self.value == other.value

a, b = A(), B()
a == b

which only prints B __eq__ called before returning False.

How do we know this full algorithm?

The other answers here seem incomplete and out of date, so I'm going to update the information and show you how how you could look this up for yourself.

This is handled at the C level.

We need to look at two different bits of code here - the default __eq__ for objects of class object, and the code that looks up and calls the __eq__ method regardless of whether it uses the default __eq__ or a custom one.

Default __eq__

Looking __eq__ up in the relevant C api docs shows us that __eq__ is handled by tp_richcompare - which in the "object" type definition in cpython/Objects/typeobject.c is defined in object_richcompare for case Py_EQ:.

    case Py_EQ:
        /* Return NotImplemented instead of False, so if two
           objects are compared, both get a chance at the
           comparison.  See issue #1393. */
        res = (self == other) ? Py_True : Py_NotImplemented;
        Py_INCREF(res);
        break;

So here, if self == other we return True, else we return the NotImplemented object. This is the default behavior for any subclass of object that does not implement its own __eq__ method.

How __eq__ gets called

Then we find the C API docs, the PyObject_RichCompare function, which calls do_richcompare.

Then we see that the tp_richcompare function, created for the "object" C definition is called by do_richcompare, so let's look at that a little more closely.

The first check in this function is for the conditions the objects being compared:

• are not the same type, but
• the second's type is a subclass of the first's type, and
• the second's type has an __eq__ method,

then call the other's method with the arguments swapped, returning the value if implemented. If that method isn't implemented, we continue...

    if (!Py_IS_TYPE(v, Py_TYPE(w)) &&
        PyType_IsSubtype(Py_TYPE(w), Py_TYPE(v)) &&
        (f = Py_TYPE(w)->tp_richcompare) != NULL) {
        checked_reverse_op = 1;
        res = (*f)(w, v, _Py_SwappedOp[op]);
        if (res != Py_NotImplemented)
            return res;
        Py_DECREF(res);

Next we see if we can lookup the __eq__ method from the first type and call it. As long as the result is not NotImplemented, that is, it is implemented, we return it.

    if ((f = Py_TYPE(v)->tp_richcompare) != NULL) {
        res = (*f)(v, w, op);
        if (res != Py_NotImplemented)
            return res;
        Py_DECREF(res);

Else if we didn't try the other type's method and it's there, we then try it, and if the comparison is implemented, we return it.

    if (!checked_reverse_op && (f = Py_TYPE(w)->tp_richcompare) != NULL) {
        res = (*f)(w, v, _Py_SwappedOp[op]);
        if (res != Py_NotImplemented)
            return res;
        Py_DECREF(res);
    }

Finally, we get a fallback in case it isn't implemented for either one's type.

The fallback checks for the identity of the object, that is, whether it is the same object at the same place in memory - this is the same check as for self is other:

    /* If neither object implements it, provide a sensible default
       for == and !=, but raise an exception for ordering. */
    switch (op) {
    case Py_EQ:
        res = (v == w) ? Py_True : Py_False;
        break;

Conclusion

In a comparison, we respect the subclass implementation of comparison first.

Then we attempt the comparison with the first object's implementation, then with the second's if it wasn't called.

Finally we use a test for identity for comparison for equality.

ng-pristine ($pristine)

Boolean True if the form/input has not been used yet (not modified by the user)

ng-dirty ($dirty)

Boolean True if the form/input has been used (modified by the user)

$setDirty(); Sets the form to a dirty state. This method can be called to add the 'ng-dirty' class and set the form to a dirty state (ng-dirty class). This method will propagate current state to parent forms.

$setPristine(); Sets the form to its pristine state. This method sets the form's $pristine state to true, the $dirty state to false, removes the ng-dirty class and adds the ng-pristine class. Additionally, it sets the $submitted state to false. This method will also propagate to all the controls contained in this form.

Setting a form back to a pristine state is often useful when we want to 'reuse' a form after saving or resetting it.

dumps takes an object and produces a string:

>>> a = {'foo': 3}
>>> json.dumps(a)
'{"foo": 3}'

load would take a file-like object, read the data from that object, and use that string to create an object:

with open('file.json') as fh:
    a = json.load(fh)

Note that dump and load convert between files and objects, while dumps and loads convert between strings and objects. You can think of the s-less functions as wrappers around the s functions:

def dump(obj, fh):
    fh.write(dumps(obj))

def load(fh):
    return loads(fh.read())

I could do this with a custom attribute as follows.

[AuthorizeUser(AccessLevel = "Create")]
public ActionResult CreateNewInvoice()
{
    //...
    return View();
}

Custom Attribute class as follows.

public class AuthorizeUserAttribute : AuthorizeAttribute
{
    // Custom property
    public string AccessLevel { get; set; }

    protected override bool AuthorizeCore(HttpContextBase httpContext)
    {
        var isAuthorized = base.AuthorizeCore(httpContext);
        if (!isAuthorized)
        {                
            return false;
        }

        string privilegeLevels = string.Join("", GetUserRights(httpContext.User.Identity.Name.ToString())); // Call another method to get rights of the user from DB

        return privilegeLevels.Contains(this.AccessLevel);           
    }
}

You can redirect an unauthorised user in your custom AuthorisationAttribute by overriding the HandleUnauthorizedRequest method:

protected override void HandleUnauthorizedRequest(AuthorizationContext filterContext)
{
    filterContext.Result = new RedirectToRouteResult(
                new RouteValueDictionary(
                    new
                        { 
                            controller = "Error", 
                            action = "Unauthorised" 
                        })
                );
}

I have issue with large calculation in sp_foo that take large time so i fixed
with this little bit code

public partial class FooEntities : DbContext
{
   public FooEntities()
         : base("name=FooEntities")
    {
        this.Configuration.LazyLoadingEnabled = false;

        // Get the ObjectContext related to this DbContext
        var objectContext = (this as IObjectContextAdapter).ObjectContext;

        // Sets the command timeout for all the commands
        objectContext.CommandTimeout = 380;
    }

A bit old question but I found myself needing this also and that the suggestions above were inaduquate - and as such - developed a thin wrapper myself: https://github.com/hofmeister/MatchIt

Check your my.cnf file in your MySQL program directory, look for

[mysqld]
datadir=

The datadir is the location where your MySQL database is stored.

java.lang.management.ManagementFactory.getRuntimeMXBean().getName().split("@")[0]

You can't access your fieldname as a global variable. Use document.getElementById:

function updateInput(ish){
    document.getElementById("fieldname").value = ish;
}

and

onchange="updateInput(this.value)"

<?php  
  
// Copy the file from /user/desktop/geek.txt

// Store the path of source file 
$source = '/user/Desktop/geek.txt';  
  
// Store the path of destination file 
$destination = 'user/Downloads/geeksforgeeks.txt';  
  
// Copy the file from /user/desktop/geek.txt

if( !copy($source, $destination) ) {  
    echo "File can't be copied! \n";  
}  
else {  
    echo "File has been copied! \n";  
}  
  
?>  

I had the same issue. And in my case the fix was pretty simple. The trick is to simply add the ".exe" to your compilers path. So, instead of :

SET(CMAKE_C_COMPILER C:/MinGW/bin/gcc)

It should be

SET(CMAKE_C_COMPILER C:/MinGW/bin/gcc.exe)

The same applies for g++.

Use find on the command line:

find /my/directory -name '*.js'

public static String toTitleCase(String word){
    return Character.toUpperCase(word.charAt(0)) + word.substring(1);
}

public static void main(String[] args){
    String phrase = "this is to be title cased";
    String[] splitPhrase = phrase.split(" ");
    String result = "";

    for(String word: splitPhrase){
        result += toTitleCase(word) + " ";
    }
    System.out.println(result.trim());
}

The real answer is: Because you cannot trust defer.

In concept, defer and async differ as follows:

async allows the script to be downloaded in the background without blocking. Then, the moment it finishes downloading, rendering is blocked and that script executes. Render resumes when the script has executed.

defer does the same thing, except claims to guarantee that scripts execute in the order they were specified on the page, and that they will be executed after the document has finished parsing. So, some scripts may finish downloading then sit and wait for scripts that downloaded later but appeared before them.

Unfortunately, due to what is really a standards cat fight, defer's definition varies spec to spec, and even in the most recent specs doesn't offer a useful guarantee. As answers here and this issue demonstrate, browsers implement defer differently:

• In certain situations some browsers have a bug that causes defer scripts to run out of order.
• Some browsers delay the DOMContentLoaded event until after the defer scripts have loaded, and some don't.
• Some browsers obey defer on <script> elements with inline code and without a src attribute, and some ignore it.

Fortunately the spec does at least specify that async overrides defer. So you can treat all scripts as async and get a wide swath of browser support like so:

<script defer async src="..."></script>

98% of browsers in use worldwide and 99% in the US will avoid blocking with this approach.

(If you need to wait until the document has finished parsing, listen to the event DOMContentLoaded event or use jQuery's handy .ready() function. You'd want to do this anyway to fall back gracefully on browsers that don't implement defer at all.)

As a rule of thumb, the safest bet towards making your document be treated properly by all web servers, proxies, and client browsers, is probably the following:

1. Use the application/xml content type
2. Include a character encoding in the content type, probably UTF-8
3. Include a matching character encoding in the encoding attribute of the XML document itself.

In terms of the RFC 3023 spec, which some browsers fail to implement properly, the major difference in the content types is in how clients are supposed to treat the character encoding, as follows:

For application/xml, application/xml-dtd, application/xml-external-parsed-entity, or any one of the subtypes of application/xml such as application/atom+xml, application/rss+xml or application/rdf+xml, the character encoding is determined in this order:

1. the encoding given in the charset parameter of the Content-Type HTTP header
2. the encoding given in the encoding attribute of the XML declaration within the document,
3. utf-8.

For text/xml, text/xml-external-parsed-entity, or a subtype like text/foo+xml, the encoding attribute of the XML declaration within the document is ignored, and the character encoding is:

1. the encoding given in the charset parameter of the Content-Type HTTP header, or
2. us-ascii.

Most parsers don't implement the spec; they ignore the HTTP Context-Type and just use the encoding in the document. With so many ill-formed documents out there, that's unlikely to change any time soon.

Take a look at the Activator.CreateInstance method.

In my case I am enabling draggable. It works.

var bootstrapDialog = new BootstrapDialog({
    title: 'Message',
    draggable: true,
    closable: false,
    size: BootstrapDialog.SIZE_WIDE,
    message: 'Hello World',
    buttons: [{
         label: 'close',
         action: function (dialogRef) {
             dialogRef.close();
         }
     }],
});
bootstrapDialog.open();

Might be it helps you.

@Leniel this method is good but you need to add width to all the floating div's. I would say make them equal width or assign fixed width. Something like

.content-wrapper > div { width:33.3%; }

you may assign class names to each div rather than adding inline style, which is not a good practice.

Be sure to use a clearfix div or clear div to avoid following content remains below these div's.

You can find details of how to use clearfix div here

One point that must be stressed out is: The .title() function must go before the .mainloop()

Example:

from tkinter import *

# Instantiating/Creating the object
main_menu = Tk()

# Set title
main_menu.title("Hello World")

# Infinite loop
main_menu.mainloop()

Otherwise, this error might occur:

File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/tkinter/__init__.py", line 2217, in wm_title
    return self.tk.call('wm', 'title', self._w, string)
_tkinter.TclError: can't invoke "wm" command: application has been destroyed

And the title won't show up on the top frame.

Use this method to convert a string to title case :

static String toTitleCase(String word) {
    return Stream.of(word.split(" "))
            .map(w -> w.toUpperCase().charAt(0)+ w.toLowerCase().substring(1))
            .reduce((s, s2) -> s + " " + s2).orElse("");
}

If you need macros (e.g. embedded system):

#define SWAP_UINT16(x) (((x) >> 8) | ((x) << 8))
#define SWAP_UINT32(x) (((x) >> 24) | (((x) & 0x00FF0000) >> 8) | (((x) & 0x0000FF00) << 8) | ((x) << 24))

The logic is simple. setOnClickListener belongs to step 2.

1. You create the button
2. You create an instance of OnClickListener* like it's done in that example and override the onClick-method.
3. You assign that OnClickListener to that button using btn.setOnClickListener(myOnClickListener); in your fragments/activities onCreate-method.
4. When the user clicks the button, the onClick function of the assigned OnClickListener is called.

*If you import android.view.View; you use View.OnClickListener. If you import android.view.View.*; or import android.view.View.OnClickListener; you use OnClickListener as far as I get it.

Another way is to let you activity/fragment inherit from OnClickListener. This way you assign your fragment/activity as the listener for your button and implement onClick as a member-function.

I'm using gcc as a preprocessor (for html files.) It does just what you want. It expands "#--" directives, then outputs a readable file. (NONE of the other C/HTML preprocessors I've tried do this- they concatenate lines, choke on special characters, etc.) Asuming you have gcc installed, the command line is:

gcc -E -x c -P -C -traditional-cpp code_before.cpp > code_after.cpp

(Doesn't have to be 'cpp'.) There's an excellent description of this usage at http://www.cs.tut.fi/~jkorpela/html/cpre.html.

The "-traditional-cpp" preserves whitespace & tabs.

If someone is searching for a complete solution for changing default charset for all database tables and converting the data, this could be one:

DELIMITER $$

CREATE PROCEDURE `exec_query`(IN sql_text VARCHAR(255))
BEGIN
  SET @tquery = `sql_text`;
  PREPARE `stmt` FROM @tquery;
  EXECUTE `stmt`;
  DEALLOCATE PREPARE `stmt`;
END$$

CREATE PROCEDURE `change_character_set`(IN `charset` VARCHAR(64), IN `collation` VARCHAR(64))
BEGIN
DECLARE `done` BOOLEAN DEFAULT FALSE;
DECLARE `tab_name` VARCHAR(64);
DECLARE `charset_cursor` CURSOR FOR 
    SELECT `table_name` FROM `information_schema`.`tables`
    WHERE `table_schema` = DATABASE() AND `table_type` = 'BASE TABLE';
DECLARE CONTINUE HANDLER FOR NOT FOUND SET `done` = TRUE;

SET foreign_key_checks = 0;
OPEN `charset_cursor`;
`change_loop`: LOOP
FETCH `charset_cursor` INTO `tab_name`;
IF `done` THEN
    LEAVE `change_loop`;
END IF;
CALL `exec_query`(CONCAT(
  'ALTER TABLE `',
  tab_name,
  '` CONVERT TO CHARACTER SET ',
  QUOTE(charset),
  ' COLLATE ',
  QUOTE(collation),
  ';'
));
CALL `exec_query`(CONCAT('REPAIR TABLE `', tab_name, '`;'));
CALL `exec_query`(CONCAT('OPTIMIZE TABLE `', tab_name, '`;'));
END LOOP `change_loop`;
CLOSE `charset_cursor`;
SET foreign_key_checks = 1;
END$$

DELIMITER ;

You can place this code inside the file e.g. chg_char_set.sql and execute it e.g. by calling it from MySQL terminal:

SOURCE ~/path-to-the-file/chg_char_set.sql

Then call defined procedure with desired input parameters e.g.

CALL change_character_set('utf8mb4', 'utf8mb4_bin');

Once you've tested the results, you can drop those stored procedures:

DROP PROCEDURE `change_character_set`;
DROP PROCEDURE `exec_query`;

Open the file using vi or nano. and then press " i " ,

For save and quit

  Enter Esc    

and write the following command

  :wq

without save and quit

  :q!

For Debian distributions. Nothing worked for until I added the debian main repositories on the apt sources (I don't know how were they removed): sudo vi /etc/apt/sources.list

and added

deb  http://deb.debian.org/debian  stretch main
deb-src  http://deb.debian.org/debian  stretch main

after that sudo apt-get update (you can upgrade too) and finally sudo apt-get install php-sqlite3

>>> list(enumerate(range(1999, 2005)))[1:]

To write to a file:

import json
myfile.write(json.dumps(mydict))

To read from a file:

import json
mydict = json.loads(myfile.read())

myfile is the file object for the file that you stored the dict in.

To remove the configs:

conda install anaconda-clean
anaconda-clean --yes

Once the configs are removed you can delete the anaconda install folder, which is usually under your home dir:

rm -rf ~/anaconda3

Also, the anaconda-clean --yes command creates a backup in your home directory of the format ~/.anaconda_backup/<timestamp>. Make sure to delete that one also.

EDIT (v5.2.0): Now if you want to clean all, you will also have to delete the two last lines added to your .bash_profile. They look like:

         ArrayList b = new ArrayList();
       int i=0,q=0;
       Random rand = new Random();

       while(a.length!=b.size())
       {
           int l = rand.nextInt(a.length);
//this is one option to that but has a flaw on 0
//           if(a[l] !=0)
//           {
//                b.add(a[l]);
//               a[l]=0;
//               
//           }
//           
// this works for every no. 
                if(!(b.contains(a[l])))
                {
                    b.add(a[l]);
                }



       }

//        for (int j = 0; j <b.size(); j++) {
//            System.out.println(b.get(j));
//            
//        }
System.out.println(b);
    }

}

In my case and while installing VS 2015 on Windows7 64x SP1, I experienced the same so tried to cancel and download/install the KBKB2999226 separately and for some reason the standalone update installer also get stuck searching for updates.

Here what I did:

1. When the VS installer stuck at the KB2999226 update I clicked cancel.
2. Installer took me back to confirm cancellation, waited for a while then opened the windows task manager and ended the process of wuse.exe (windows standalone update installer)
3. On the VS installer clicked "No" to return to installation process. The process was completed without errors.

UPDATE

In Android Studio AVD:

1. Open AVD Manager:

2. Add/Edit AVD:

3. Click Advanced Settings in the bottom of the screen:

4. Set your camera of choice as the front/back cameras:

You can install it by first extracting all the files from the ISO and then overwriting those files with the files from the ZIP. Then you can run the batch file as administrator to do the installation. Most of the packages install on windows 7, but I haven't tested yet how well they work.

I know its long after this question was asked and answered - and I am sure that the accepted solution is right, but the purist in me would rather not add an extra element to the SVG when I can achieve the same or similar with straight CSS.

Whilst it is true that you cannot style the g container element in most ways - you can definitely add an outline to it and style that - even changing it on hover of the g - as shown in the snippet.

It not as good in one regard as the other way - you can put the outline box around the grouped elements - but not a background behind it. Sot its not perfect and won't solve the issue for everyone - but I would rather have the outline done with css than have to add extra elements to the code just to provide styling hooks.

And this method definitely allows you to show grouping of related objects in your SVG's.

Just a thought.

g {_x000D_
    outline: solid 3px blue;_x000D_
    outline-offset: 5px;_x000D_
  }_x000D_
_x000D_

Perhaps you're looking for the x86_64 ABI?

• www.x86-64.org/documentation/abi.pdf (404 at 2018-11-24)
• www.x86-64.org/documentation/abi.pdf (via Wayback Machine at 2018-11-24)
• Where is the x86-64 System V ABI documented? - https://github.com/hjl-tools/x86-psABI/wiki/X86-psABI is kept up to date (by HJ Lu, one of the ABI maintainers) with links to PDFs of the official current version.

If that's not precisely what you're after, use 'x86_64 abi' in your preferred search engine to find alternative references.

Two suggestions:

1. Use std::deque instead of std::vector for better performance in your specific case and use the method std::deque::pop_front().
2. Rethink (I mean: delete) the & in std::vector<ScanRule>& topPriorityRules;

Also make sure the aspx page has AutoEventWireup="true" and not AutoEventWireup="false"

Use a Temp Table or a Table variable, e.g.

select 'A' as [value]
into #tmp
union
select 'B'
union 
select 'C'

and then

SELECT   
blah 
FROM    foo 
WHERE   myField IN (select [value] from #tmp) 

or

SELECT   
f.blah 
FROM foo f INNER JOIN #tmp t ON f.myField = t.[value]

Replace all non-digit with blank: the remaining string contains only digits.

Integer.parseInt(s.replaceAll("[\\D]", ""))

This will also remove non-digits inbetween digits, so "x1x1x" becomes 11.

If you need to confirm that the string consists of a sequence of digits (at least one) possibly followed a letter, then use this:

s.matches("[\\d]+[A-Za-z]?")

try this function

function summary($str, $limit=100, $strip = false) {
    $str = ($strip == true)?strip_tags($str):$str;
    if (strlen ($str) > $limit) {
        $str = substr ($str, 0, $limit - 3);
        return (substr ($str, 0, strrpos ($str, ' ')).'...');
    }
    return trim($str);
}

Here is what I would recommend.

It should conform to C89, and be completely portable. In particular, it works also on pipes and sockets on POSIXy systems.

The idea is that we read the input in large-ish chunks (READALL_CHUNK), dynamically reallocating the buffer as we need it. We only use realloc(), fread(), ferror(), and free():

#include <stdlib.h>
#include <stdio.h>
#include <errno.h>

/* Size of each input chunk to be
   read and allocate for. */
#ifndef  READALL_CHUNK
#define  READALL_CHUNK  262144
#endif

#define  READALL_OK          0  /* Success */
#define  READALL_INVALID    -1  /* Invalid parameters */
#define  READALL_ERROR      -2  /* Stream error */
#define  READALL_TOOMUCH    -3  /* Too much input */
#define  READALL_NOMEM      -4  /* Out of memory */

/* This function returns one of the READALL_ constants above.
   If the return value is zero == READALL_OK, then:
     (*dataptr) points to a dynamically allocated buffer, with
     (*sizeptr) chars read from the file.
     The buffer is allocated for one extra char, which is NUL,
     and automatically appended after the data.
   Initial values of (*dataptr) and (*sizeptr) are ignored.
*/
int readall(FILE *in, char **dataptr, size_t *sizeptr)
{
    char  *data = NULL, *temp;
    size_t size = 0;
    size_t used = 0;
    size_t n;

    /* None of the parameters can be NULL. */
    if (in == NULL || dataptr == NULL || sizeptr == NULL)
        return READALL_INVALID;

    /* A read error already occurred? */
    if (ferror(in))
        return READALL_ERROR;

    while (1) {

        if (used + READALL_CHUNK + 1 > size) {
            size = used + READALL_CHUNK + 1;

            /* Overflow check. Some ANSI C compilers
               may optimize this away, though. */
            if (size <= used) {
                free(data);
                return READALL_TOOMUCH;
            }

            temp = realloc(data, size);
            if (temp == NULL) {
                free(data);
                return READALL_NOMEM;
            }
            data = temp;
        }

        n = fread(data + used, 1, READALL_CHUNK, in);
        if (n == 0)
            break;

        used += n;
    }

    if (ferror(in)) {
        free(data);
        return READALL_ERROR;
    }

    temp = realloc(data, used + 1);
    if (temp == NULL) {
        free(data);
        return READALL_NOMEM;
    }
    data = temp;
    data[used] = '\0';

    *dataptr = data;
    *sizeptr = used;

    return READALL_OK;
}

Above, I've used a constant chunk size, READALL_CHUNK == 262144 (256*1024). This means that in the worst case, up to 262145 chars are wasted (allocated but not used), but only temporarily. At the end, the function reallocates the buffer to the optimal size. Also, this means that we do four reallocations per megabyte of data read.

The 262144-byte default in the code above is a conservative value; it works well for even old minilaptops and Raspberry Pis and most embedded devices with at least a few megabytes of RAM available for the process. Yet, it is not so small that it slows down the operation (due to many read calls, and many buffer reallocations) on most systems.

For desktop machines at this time (2017), I recommend a much larger READALL_CHUNK, perhaps #define READALL_CHUNK 2097152 (2 MiB).

Because the definition of READALL_CHUNK is guarded (i.e., it is defined only if it is at that point in the code still undefined), you can override the default value at compile time, by using (in most C compilers) -DREADALL_CHUNK=2097152 command-line option -- but do check your compiler options for defining a preprocessor macro using command-line options.

As always with Android there's lots of ways to do this, but assuming you simply want to run a piece of code a little bit later on the same thread, I use this:

new android.os.Handler(Looper.getMainLooper()).postDelayed(
    new Runnable() {
        public void run() {
            Log.i("tag", "This'll run 300 milliseconds later");
        }
    }, 
300);

.. this is pretty much equivalent to

setTimeout( 
    function() {
        console.log("This will run 300 milliseconds later");
    },
300);

It can solve this problem by cd command, this command understand spaces without double quotes and you can call any program this way for example:

C:\Windows\system32>cd c:\Program Files\MongoDB\Server\3.2\bin

c:\Program Files\MongoDB\Server\3.2\bin>mongo now command prompt call mongo.exe

This code will add an event listener to the default local Inbox, then take some action on incoming emails. You need to add that action in the code below.

Private WithEvents Items As Outlook.Items 
Private Sub Application_Startup() 
  Dim olApp As Outlook.Application 
  Dim objNS As Outlook.NameSpace 
  Set olApp = Outlook.Application 
  Set objNS = olApp.GetNamespace("MAPI") 
  ' default local Inbox
  Set Items = objNS.GetDefaultFolder(olFolderInbox).Items 
End Sub
Private Sub Items_ItemAdd(ByVal item As Object) 

  On Error Goto ErrorHandler 
  Dim Msg As Outlook.MailItem 
  If TypeName(item) = "MailItem" Then
    Set Msg = item 
    ' ******************
    ' do something here
    ' ******************
  End If
ProgramExit: 
  Exit Sub
ErrorHandler: 
  MsgBox Err.Number & " - " & Err.Description 
  Resume ProgramExit 
End Sub

After pasting the code in ThisOutlookSession module, you must restart Outlook.

when you start in cygwin, you are in your $HOME, like in unix generally, which maps to c:/cygwin/home/$YOURNAME by default. So you could put everything there.

You can also access the c: drive from cygwin through /cygdrive/c/ (e.g. /cygdrive/c/Documents anb Settings/yourname/Desktop).

I thought my simple "all possible combination generator" might help someone, i think its a really good example for building something bigger and better

you can change N (characters) to any you like by just removing/adding from string array (you can change it to int as well). Current amount of characters is 36

you can also change K (size of the generated combinations) by just adding more loops, for each element, there must be one extra loop. Current size is 4

#include<iostream>

using namespace std;

int main() {
string num[] = {"0","1","2","3","4","5","6","7","8","9","a","b","c","d","e","f","g","h","i","j","k","l","m","n","o","p","q","r","s","t","u","v","w","x","y","z" };

for (int i1 = 0; i1 < sizeof(num)/sizeof(string); i1++) {
    for (int i2 = 0; i2 < sizeof(num)/sizeof(string); i2++) {
        for (int i3 = 0; i3 < sizeof(num)/sizeof(string); i3++) {
            for (int i4 = 0; i4 < sizeof(num)/sizeof(string); i4++) {
                cout << num[i1] << num[i2] << num[i3] << num[i4] << endl;
            }
        }
    }
}}

Result

0: A A A
1: B A A
2: C A A
3: A B A
4: B B A
5: C B A
6: A C A
7: B C A
8: C C A
9: A A B
...

just keep in mind that the amount of combinations can be ridicules.

--UPDATE--

a better way to generate all possible combinations would be with this code, which can be easily adjusted and configured in the "variables" section of the code.

#include<iostream>
#include<math.h>

int main() {
    //VARIABLES
    char chars[] = { 'A', 'B', 'C' };
    int password[4]{0};

    //SIZES OF VERIABLES
    int chars_length = sizeof(chars) / sizeof(char);
    int password_length = sizeof(password) / sizeof(int);

    //CYCKLE TROUGH ALL OF THE COMBINATIONS
    for (int i = 0; i < pow(chars_length, password_length); i++){
       
        //CYCKLE TROUGH ALL OF THE VERIABLES IN ARRAY
        for (int i2 = 0; i2 < password_length; i2++) {
            //IF VERIABLE IN "PASSWORD" ARRAY IS THE LAST VERIABLE IN CHAR "CHARS" ARRRAY
            if (password[i2] == chars_length) {
                //THEN INCREMENT THE NEXT VERIABLE IN "PASSWORD" ARRAY
                password[i2 + 1]++;
                //AND RESET THE VERIABLE BACK TO ZERO
                password[i2] = 0;
            }}

        //PRINT OUT FIRST COMBINATION
        std::cout << i << ": ";
        for (int i2 = 0; i2 < password_length; i2++) {
            std::cout << chars[password[i2]] << " ";
        }
        std::cout << "\n";

        //INCREMENT THE FIRST VERIABLE IN ARRAY
        password[0]++;
    }}

    

If there is anything in <table> you don't like, maybe you could use reset file?

An additional note to the get_python_lib function mentioned already: on some platforms different directories are used for platform specific modules (eg: modules that require compilation). If you pass plat_specific=True to the function you get the site packages for platform specific packages.

I think the problem you are facing is almost this: -

str = str.replace("-", ' ');

You need to re-assign the result of the replacement to str, to see the reflected change.

From MSDN Javascript reference: -

The result of the replace method is a copy of stringObj after the specified replacements have been made.

To replace all the -, you would need to use /g modifier with a regex parameter: -

str = str.replace(/-/g, ' ');

I would also recommend to use Notepad++ with json-view extension. You get the extension here: https://sourceforge.net/projects/nppjsonviewer/ Install and restart Notepad++. Then open json-file in Notepad and go to "extensions -> Json-Viewer - > Format JSON. Then you habe the hierarchical view of json.

You can also use one of the online-viewers (http://jsonviewer.stack.hu/ , https://jsoneditoronline.org/) which look nice, but I wouldn't recommend this if your data are sensitive in terms of privacy.

if you want to bookkeep some variable before page refresh

$(window).on('beforeunload', function(){
    // your logic here
});

if you want o load some content base on some condition

$(window).on('load', function(){
    // your logic here`enter code here`
});

To remove the association between the local and remote branch run:

git config --unset branch.<local-branch-name>.remote
git config --unset branch.<local-branch-name>.merge

Optionally delete the local branch afterwards if you don't need it:

git branch -d <branch>

This won't delete the remote branch.

With Java 8 it is so simple so it doesn't even need separate method anymore:

List<Integer> range = IntStream.rangeClosed(start, end)
    .boxed().collect(Collectors.toList());

To get the output of ls, use stdout=subprocess.PIPE.

>>> proc = subprocess.Popen('ls', stdout=subprocess.PIPE)
>>> output = proc.stdout.read()
>>> print output
bar
baz
foo

The command cdrecord --help outputs to stderr, so you need to pipe that indstead. You should also break up the command into a list of tokens as I've done below, or the alternative is to pass the shell=True argument but this fires up a fully-blown shell which can be dangerous if you don't control the contents of the command string.

>>> proc = subprocess.Popen(['cdrecord', '--help'], stderr=subprocess.PIPE)
>>> output = proc.stderr.read()
>>> print output
Usage: wodim [options] track1...trackn
Options:
    -version    print version information and exit
    dev=target  SCSI target to use as CD/DVD-Recorder
    gracetime=# set the grace time before starting to write to #.
...

If you have a command that outputs to both stdout and stderr and you want to merge them, you can do that by piping stderr to stdout and then catching stdout.

subprocess.Popen(cmd, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)

As mentioned by Chris Morgan, you should be using proc.communicate() instead of proc.read().

>>> proc = subprocess.Popen(['cdrecord', '--help'], stdout=subprocess.PIPE, stderr=subprocess.PIPE)
>>> out, err = proc.communicate()
>>> print 'stdout:', out
stdout: 
>>> print 'stderr:', err
stderr:Usage: wodim [options] track1...trackn
Options:
    -version    print version information and exit
    dev=target  SCSI target to use as CD/DVD-Recorder
    gracetime=# set the grace time before starting to write to #.
...

You just use this: if not exist "C:\VTS\" mkdir C:\VTS it wll create a directory only if the folder does not exist.

Note that this existence test will return true only if VTS exists and is a directory. If it is not there, or is there as a file, the mkdir command will run, and should cause an error. You might want to check for whether VTS exists as a file as well.

There is just a caveat that I discovered today. If you have a function that is calling a plot a lot of times you better use plt.close(fig) instead of fig.clf() somehow the first does not accumulate in memory. In short if memory is a concern use plt.close(fig) (Although it seems that there are better ways, go to the end of this comment for relevant links).

So the the following script will produce an empty list:

for i in range(5):
    fig = plot_figure()
    plt.close(fig)
# This returns a list with all figure numbers available
print(plt.get_fignums())

Whereas this one will produce a list with five figures on it.

for i in range(5):
    fig = plot_figure()
    fig.clf()
# This returns a list with all figure numbers available
print(plt.get_fignums())

From the documentation above is not clear to me what is the difference between closing a figure and closing a window. Maybe that will clarify.

If you want to try a complete script there you have:

import numpy as np
import matplotlib.pyplot as plt
x = np.arange(1000)
y = np.sin(x)

for i in range(5):
    fig = plt.figure()
    ax = fig.add_subplot(1, 1, 1)
    ax.plot(x, y)
    plt.close(fig)

print(plt.get_fignums())

for i in range(5):
    fig = plt.figure()
    ax = fig.add_subplot(1, 1, 1)
    ax.plot(x, y)
    fig.clf()

print(plt.get_fignums())

If memory is a concern somebody already posted a work-around in SO see: Create a figure that is reference counted

$("label[for='"+$(this).attr("id")+"']");

This should allow you to select labels for all the fields in a loop as well. All you need to ensure is your labels should say for='FIELD' where FIELD is the id of the field for which this label is being defined.

If you want to keep reference:

Array.prototype.push.apply(destinationArray, sourceArray);

This should work for you

 public class MyActivity extends Activity {

    protected ProgressDialog mProgressDialog;
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        populateTable();
    }

    private void populateTable() {
        mProgressDialog = ProgressDialog.show(this, "Please wait","Long operation starts...", true);
        new Thread() {
            @Override
            public void run() {

                doLongOperation();
                try {

                    // code runs in a thread
                    runOnUiThread(new Runnable() {
                        @Override
                        public void run() {
                            mProgressDialog.dismiss();
                        }
                    });
                } catch (final Exception ex) {
                    Log.i("---","Exception in thread");
                }
            }
        }.start();

    }

    /** fake operation for testing purpose */
    protected void doLongOperation() {
        try {
            Thread.sleep(10000);
        } catch (InterruptedException e) {
        }

    }
}

You can use String.Join. If you have a List<string> then you can call ToArray first:

List<string> names = new List<string>() { "John", "Anna", "Monica" };
var result = String.Join(", ", names.ToArray());

In .NET 4 you don't need the ToArray anymore, since there is an overload of String.Join that takes an IEnumerable<string>.

Results:

John, Anna, Monica

For me the problem was in that I had not yet ran composer update for this new project/fork. The command failed silently, nothing happened.

After running composer update it worked.

No there is no special attribute you can use. JavaScriptSerializer serializes enums to their numeric values and not their string representation. You would need to use custom serialization to serialize the enum as its name instead of numeric value.

If you can use JSON.Net instead of JavaScriptSerializer than see answer on this question provided by OmerBakhari: JSON.net covers this use case (via the attribute [JsonConverter(typeof(StringEnumConverter))]) and many others not handled by the built in .net serializers. Here is a link comparing features and functionalities of the serializers.

"top" is usually available on Solaris.

If not then revert to "vmstat" which is available on most UNIX system.

It should look something like this (from an AIX box)

vmstat

the colums "avm" and "fre" tell you the total memory and free memery.

a "man vmstat" should get you the gory details.

This is even easier :

$('html').click(function(e) {
    $('.popup-marker').popover('hide');
});

$('.popup-marker').popover({
    html: true,
    trigger: 'manual'
}).click(function(e) {
    $(this).popover('toggle');
    e.stopPropagation();
});

On the 1st iteration of the outer loop (i = 1), the inner loop will iterate 1 times On the 2nd iteration of the outer loop (i = 2), the inner loop will iterate 2 time On the 3rd iteration of the outer loop (i = 3), the inner loop will iterate 3 times
.
.
On the FINAL iteration of the outer loop (i = n), the inner loop will iterate n times

So, the total number of times the statements in the inner loop will be executed will be equal to the sum of the integers from 1 to n, which is:

((n)*n) / 2 = (n^2)/2 = O(n^2) times 

I wouldn't use this on a live site due to XSS attacks and probably plenty of other issues, but here's a quick example of what you could do:

$("#myform").submit(function(){
    var arr = $(this).serializeArray();
    var json = "";
    jQuery.each(arr, function(){
        jQuery.each(this, function(i, val){
            if (i=="name") {
                json += '"' + val + '":';
            } else if (i=="value") {
                json += '"' + val.replace(/"/g, '\\"') + '",';
            }
        });
    });
    json = "{" + json.substring(0, json.length - 1) + "}";
    // do something with json
    return false;
});

What I did was to create a canvas element that I then position in front of the image map. Then, whenever an area is moused-over, I call a func that gets the coord string for that shape and the shape-type. If it's a poly I use the coords to draw an outline on the canvas. If it's a rect I draw a rect outline. You could easily add code to deal with circles.

You could also set the opacity of the canvas to less than 100% before filling the poly/rect/circle. You could also change the reliance on a global for the canvas's context - this would mean you could deal with more than 1 image-map on the same page.

Sometimes it's more simple to implement a copy constructor:

public MyObject (MyObject toClone) {
}

It saves you the trouble of handling CloneNotSupportedException, works with final fields and you don't have to worry about the type to return.

Swift 4:

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
    if segue.identifier == "ExampleSegueIdentifier" {
        if let destinationVC = segue.destination as? ExampleSegueVC {
            destinationVC.exampleString = "Example"
        }
    }
}

Swift 3:

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
        if segue.identifier == "ExampleSegueIdentifier" {
            if let destinationVC = segue.destinationViewController as? ExampleSegueVC {
                destinationVC.exampleString = "Example"
            }
        }
    }

I suspect you haven't set up last_name properly in the caller.

With the statement Worksheets(data_sheet).Range("C2").Value = ProcessString(last_name)

this will only work if last_name is a string, i.e.

Dim last_name as String

appears in the caller somewhere.

The reason for this is that VBA passes in variables by reference by default which means that the data types have to match exactly between caller and callee.

Two fixes:

1) Force ByVal -- Change your function to pass variable ByVal:
Public Function ProcessString(ByVal input_string As String) As String, or

2) Dim varname -- put Dim last_name As String in the caller before you use it.

(1) works because for ByVal, a copy of input_string is taken when passing to the function which will coerce it into the correct data type. It also leads to better program stability since the function cannot modify the variable in the caller.

A visual answer

Imagine a <span> element inside a <div>. If you give the <span> element a height of 100px and a red border for example, it will look like this with

display: inline

display: inline-block

display: block

Code: http://jsfiddle.net/Mta2b/

Elements with display:inline-block are like display:inline elements, but they can have a width and a height. That means that you can use an inline-block element as a block while flowing it within text or other elements.

Difference of supported styles as summary:

• inline: only margin-left, margin-right, padding-left, padding-right
• inline-block: margin, padding, height, width

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

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

$ nc -l -p 8080

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

And got the following http-headers without setRequestProperty:

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

And WITH setRequestProperty:

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

As you can see the user agent was properly set.

Full example:

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


public class TestUrlOpener {

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

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

}

On Angular 1.5 - after trying some of the above solutions wanting to reload only the data with no full page refresh, I had problems with loading the data properly. I noticed though, that when I go to another route and then I return back to the current, everything works fine, but when I want to only reload the current route using $route.reload(), then some of the code is not executed properly. Then I tried to redirect to the current route in the following way:

$scope.someFuncName = function () {
    //go to another route
    $location.path('/another-route');
};

and in the module config, add another when:

.config(['$routeProvider', function($routeProvider) {
     $routeProvider.when('/first-page', {
         templateUrl: '/first-template',
         controller: 'SomeCtrl'
     }).when('/another-route', {//this is the new "when"
         redirectTo: '/first-page'
     });
}])

and it works just fine for me. It does not refresh the whole page, but only causes the current controller and template to reload. I know it's a bit hacky, but that was the only solution I found.

To break a $.each or $(selector).each loop, you have to return false in the loop callback.

Returning true skips to the next iteration, equivalent to a continue in a normal loop.

$.each(array, function(key, value) { 
    if(value === "foo") {
        return false; // breaks
    }
});

// or

$(selector).each(function() {
  if (condition) {
    return false;
  }
});

Postgres hasn't implemented an equivalent to INSERT OR REPLACE. From the ON CONFLICT docs (emphasis mine):

It can be either DO NOTHING, or a DO UPDATE clause specifying the exact details of the UPDATE action to be performed in case of a conflict.

Though it doesn't give you shorthand for replacement, ON CONFLICT DO UPDATE applies more generally, since it lets you set new values based on preexisting data. For example:

INSERT INTO users (id, level)
VALUES (1, 0)
ON CONFLICT (id) DO UPDATE
SET level = users.level + 1;

LR is link register used to hold the return address for a function call.

SP is stack pointer. The stack is generally used to hold "automatic" variables and context/parameters across function calls. Conceptually you can think of the "stack" as a place where you "pile" your data. You keep "stacking" one piece of data over the other and the stack pointer tells you how "high" your "stack" of data is. You can remove data from the "top" of the "stack" and make it shorter.

From the ARM architecture reference:

SP, the Stack Pointer

Register R13 is used as a pointer to the active stack.

In Thumb code, most instructions cannot access SP. The only instructions that can access SP are those designed to use SP as a stack pointer. The use of SP for any purpose other than as a stack pointer is deprecated. Note Using SP for any purpose other than as a stack pointer is likely to break the requirements of operating systems, debuggers, and other software systems, causing them to malfunction.

LR, the Link Register

Register R14 is used to store the return address from a subroutine. At other times, LR can be used for other purposes.

When a BL or BLX instruction performs a subroutine call, LR is set to the subroutine return address. To perform a subroutine return, copy LR back to the program counter. This is typically done in one of two ways, after entering the subroutine with a BL or BLX instruction:

• Return with a BX LR instruction.

• On subroutine entry, store LR to the stack with an instruction of the form: PUSH {,LR} and use a matching instruction to return: POP {,PC} ...

This link gives an example of a trivial subroutine.

Here is an example of how registers are saved on the stack prior to a call and then popped back to restore their content.

I found this post trying to figure why I kept getting the following error which is explained by the other answers.

The conversion of a datetime2 data type to a datetime data type resulted in an out-of-range value.

Use a nullable DateTime object.
public DateTime? PurchaseDate { get; set; }

If you are using entity framework Set the nullable property in the edmx file to True

You can do this using Input.setSelectionRange, part of the Range API for interacting with text selections and the text cursor:

var searchInput = $('#Search');

// Multiply by 2 to ensure the cursor always ends up at the end;
// Opera sometimes sees a carriage return as 2 characters.
var strLength = searchInput.val().length * 2;

searchInput.focus();
searchInput[0].setSelectionRange(strLength, strLength);

Demo: Fiddle

Well, you could swap your 0's for NA and then use one of those solutions, but for sake of a difference, you could notice that a number will only have a finite logarithm if it is greater than 0, so that rowSums of the log will only be finite if there are no zeros in a row.

dfr[is.finite(rowSums(log(dfr[-1]))),]

Also, if you have Toad for Oracle, you can highlight the statement and press CTRL + F9 and you'll get a nice view of column and their datatypes.

Can you describe the paradigm shift that is necessary?

Imperative vs Declarative

With jQuery you tell the DOM what needs to happen, step by step. With AngularJS you describe what results you want but not how to do it. More on this here. Also, check out Mark Rajcok's answer.

How do I architect and design client-side web apps differently?

AngularJS is an entire client-side framework that uses the MVC pattern (check out their graphical representation). It greatly focuses on separation of concerns.

What is the biggest difference? What should I stop doing/using; what should I start doing/using instead?

jQuery is a library

AngularJS is a beautiful client-side framework, highly testable, that combines tons of cool stuff such as MVC, dependency injection, data binding and much more.

It focuses on separation of concerns and testing (unit testing and end-to-end testing), which facilitates test-driven development.

The best way to start is going through their awesome tutorial. You can go through the steps in a couple of hours; however, in case you want to master the concepts behind the scenes, they include a myriad of reference for further reading.

Are there any server-side considerations/restrictions?

You may use it on existing applications where you are already using pure jQuery. However, if you want to fully take advantage of the AngularJS features you may consider coding the server side using a RESTful approach.

Doing so will allow you to leverage their resource factory, which creates an abstraction of your server side RESTful API and makes server-side calls (get, save, delete, etc.) incredibly easy.

Java 8

import java.util.Arrays;
import java.util.List;
import java.util.ArrayList;

public class HelloWorld{

     public static void main(String []args){
            List<List<String>> stringListList = new ArrayList<>();
            stringListList.add(Arrays.asList(new String[] {"(0,0)", "(0,1)"} ));
            stringListList.add(Arrays.asList(new String[] {"(1,0)", "(1,1)", "(1,2)"} ));
            stringListList.add(Arrays.asList(new String[] {"(2,0)", "(2,1)"} ));

            int count=stringListList.stream().mapToInt(i -> i.size()).sum();

            System.out.println("stringListList count: "+count);
     }
}

You can set data to session simply like this in Codeigniter:

$this->load->library('session');
$this->session->set_userdata(array(
    'user_id'  => $user->uid,
    'username' => $user->username,
    'groupid'  => $user->groupid,
    'date'     => $user->date_cr,
    'serial'   => $user->serial,
    'rec_id'   => $user->rec_id,
    'status'   => TRUE
));

and you can get it like this:

$u_rec_id = $this->session->userdata('rec_id');
$serial = $this->session->userdata('serial');

a bit late to this, but yes rabbitmq has a build in tracer that allows you to see the incomming messages in a log. When enabled, you can just tail -f /var/tmp/rabbitmq-tracing/.log (on mac) to watch the messages.

In Android Studio, open the Device Manager: Tools -> Android -> Android Device Monitor

In Eclipse open the Device Manager:

In the device manager you can add files to the SD Card here:

new Date().toTimeString().slice(0,8)

Note that toLocaleTimeString() might return something like 9:00:00 AM.

c_str() converts a C++ string into a C-style string which is essentially a null terminated array of bytes. You use it when you want to pass a C++ string into a function that expects a C-style string (e.g. a lot of the Win32 API, POSIX style functions, etc).

This is a hairy one to answer, because you didn't give the full context of what you're doing. The accepted answer will work, but in some cases will cause poor performance. That, and it's going to be harder to test.

If you're doing this as part of a static form, fine. The accepted answer will work, even if it isn't easy to test, and it's hinky.

If you want to be "Angular" about this:

You'll want to keep any "business logic" (i.e. logic that alters data to be displayed) out of your views. This is so you can unit test your logic, and so you don't end up tightly coupling your controller and your view. Theoretically, you should be able to point your controller at another view and use the same values from the scopes. (if that makes sense).

You'll also want to consider that any function calls inside of a binding (such as {{}} or ng-bind or ng-bind-html) will have to be evaluated on every digest, because angular has no way of knowing if the value has changed or not like it would with a property on the scope.

The "angular" way to do this would be to cache the value in a property on the scope on change using an ng-change event or even a $watch.

For example with a static form:

angular.controller('MainCtrl', function($scope, $window) {
   $scope.count = 0;
   $scope.total = 1;

   $scope.updatePercentage = function () {
      $scope.percentage = $window.Math.round((100 * $scope.count) / $scope.total);
   };
});

<form name="calcForm">
   <label>Count <input name="count" ng-model="count" 
                  ng-change="updatePercentage()"
                  type="number" min="0" required/></label><br/>
   <label>Total <input name="total" ng-model="total"
                  ng-change="updatePercentage()"
                  type="number" min="1" required/></label><br/>
   <hr/>
   Percentage: {{percentage}}
</form>

And now you can test it!

describe('Testing percentage controller', function() {
  var $scope = null;
  var ctrl = null;

  //you need to indicate your module in a test
  beforeEach(module('plunker'));

  beforeEach(inject(function($rootScope, $controller) {
    $scope = $rootScope.$new();

    ctrl = $controller('MainCtrl', {
      $scope: $scope
    });
  }));

  it('should calculate percentages properly', function() {
    $scope.count = 1;
    $scope.total = 1;
    $scope.updatePercentage();
    expect($scope.percentage).toEqual(100);

    $scope.count = 1;
    $scope.total = 2;
    $scope.updatePercentage();
    expect($scope.percentage).toEqual(50);

    $scope.count = 497;
    $scope.total = 10000;
    $scope.updatePercentage();
    expect($scope.percentage).toEqual(5); //4.97% rounded up.

    $scope.count = 231;
    $scope.total = 10000;
    $scope.updatePercentage();
    expect($scope.percentage).toEqual(2); //2.31% rounded down.
  });
});
