Programs & Examples On #Uikit

This has changed a lot in iOS 9 (in iOS 8 it's pretty similar to what we're seeing here). If you can afford to target iOS 9 only, then you resize the UIPickerView as you see fit, by setting its frame. Good!

Here it is from iOS 9 Release Notes

UIPickerView and UIDatePicker are now resizable and adaptive—previously, these views would enforce a default size even if you attempted to resize them. These views also now default to a width of 320 points on all devices, instead of to the device width on iPhone.

Interfaces that rely on the old enforcement of the default size will likely look wrong when compiled for iOS 9. Any problems encountered can be resolved by fully constraining or sizing picker views to the desired size instead of relying on implicit behavior.

There are two ways to fix this problem.One is

[mylabel setNumberOfLines:0];
[mylabel sizeToFit];

But the second way is more reliable for this approach, i.e,

 CGSize sizeToFit = [label.text sizeWithFont:label.font constrainedToSize:maxSize lineBreakMode:label.lineBreakMode];
 [mylabel setFrame:CGRectMake(mylabel.frame.origin.x, mylabel.frame.origin.y, sizeToFit.width, sizeToFit.height)];

entering "\n" is not such a good thing but yes if you know the constraints and the size of the data going to be displayed, may be it work good but cannot be expandable if text is longer than size of the label. The Second way ultimately set the frame according to the size of the text going to be displayed.

Just put this blur view on the imageView. Here is an example in Objective-C:

UIVisualEffect *blurEffect;
blurEffect = [UIBlurEffect effectWithStyle:UIBlurEffectStyleLight];

UIVisualEffectView *visualEffectView;
visualEffectView = [[UIVisualEffectView alloc] initWithEffect:blurEffect];

visualEffectView.frame = imageView.bounds;
[imageView addSubview:visualEffectView];

and Swift:

var visualEffectView = UIVisualEffectView(effect: UIBlurEffect(style: .Light))    

visualEffectView.frame = imageView.bounds

imageView.addSubview(visualEffectView)

To simplify this actions from accepted answer, you can also create Category for UIView (since this works for all subclasses of UIView, not only for textfields:

UIView+Additions.h:

#import <Foundation/Foundation.h>

@interface UIView (Additions)
- (void)setBorderForColor:(UIColor *)color 
                    width:(float)width 
                   radius:(float)radius;
@end

UIView+Additions.m:

#import "UIView+Additions.h"

@implementation UIView (Additions)

- (void)setBorderForColor:(UIColor *)color 
                    width:(float)width
                   radius:(float)radius
{
    self.layer.cornerRadius = radius;
    self.layer.masksToBounds = YES;
    self.layer.borderColor = [color CGColor];
    self.layer.borderWidth = width;
}

@end

Usage:

#import "UIView+Additions.h"
//...
[textField setBorderForColor:[UIColor redColor]
                       width:1.0f
                      radius:8.0f];

You can do this

[self performSelector:@selector(MethodToExecute) withObject:nil afterDelay:1.0 ];

I solved this by subclassing UILabel and overriding drawTextInRect: like this:

- (void)drawTextInRect:(CGRect)rect {
    UIEdgeInsets insets = {0, 5, 0, 5};
    [super drawTextInRect:UIEdgeInsetsInsetRect(rect, insets)];
}

Swift 3.1:

override func drawText(in rect: CGRect) {
    let insets = UIEdgeInsets.init(top: 0, left: 5, bottom: 0, right: 5)
    super.drawText(in: UIEdgeInsetsInsetRect(rect, insets))
}

Swift 4.2.1:

override func drawText(in rect: CGRect) {
    let insets = UIEdgeInsets(top: 0, left: 5, bottom: 0, right: 5)
    super.drawText(in: rect.inset(by: insets))
}

As you might have gathered, this is an adaptation of tc.'s answer. It has two advantages over that one:

1. there's no need to trigger it by sending a sizeToFit message
2. it leaves the label frame alone - handy if your label has a background and you don't want that to shrink

if you are like me who has tried all the above solutions and still your problem is not solved, I have a got a great solution for you that works like a charm. First I want clarify few things about some of solutions mentioned above.

1. In my case IQkeyboardmanager was working only when there is no auto layout applied on the elements, if it is applied then IQkeyboard manager will not work the way we think.
2. Same thing with upward movement of self.view.
3. i have wriiten a objective c header with a swift support for pushing UITexfield upward when user clicks on it, solving the problem of keyboard covering the UITextfield : https://github.com/coolvasanth/smart_keyboard.
4. One who has An intermediate or higher level in iOS app development can easily understand the repository and implement it. All the best

This workaround was written in 2009 when IOS 3.0 was released. It no longer applies.

I ran into the exact same problem, in the end I had to wind up using

nameField.contentInset = UIEdgeInsetsMake(-4,-8,0,0);

where nameField is a UITextView. The font I happened to be using was Helvetica 16 point. Its only a custom solution for the particular field size I was drawing. This makes the left offset flush with the left side, and the top offset where I want it for the box its draw in.

In addition, this only seems to apply to UITextViews where you are using the default aligment, ie.

nameField.textAlignment = NSTextAlignmentLeft;

Align to the right for example and the UIEdgeInsetsMake seems to have no impact on the right edge at all.

At very least, using the .contentInset property allows you to place your fields with the "correct" positions, and accommodate the deviations without offsetting your UITextViews.

As strange as this seems, the following code solved the problem for me:

+ (UIImage*)unrotateImage:(UIImage*)image {
    CGSize size = image.size;
    UIGraphicsBeginImageContext(size);
    [image drawInRect:CGRectMake(0,0,size.width ,size.height)];
    UIImage* newImage = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();

    return newImage;
}

In interface Builder set table view separator "None"

and those separator lines which are shown after the last cell can be remove by following approach. Best approach is to assign Empty View to tableView FooterView in viewDidLoad

self.tableView.tableFooterView = UIView()

The solution we ended up with is similar to many of the others. But to get the correct position of the separator we had to set it before calling super.layoutSubviews(). Simplified example:

class ImageTableViewCell: UITableViewCell {

    override func layoutSubviews() {
        separatorInset.left = 70
        super.layoutSubviews()

        imageView?.frame = CGRect(x: 0, y: 0, width: 50, height: 50)
        textLabel?.frame = CGRect(x: 70, y: 0, width: 200, height: 50)
    }

}

Not sure how efficient this is, but I wrote this function that returns the point size that will fit a string to a given width:

func fontSizeThatFits(targetWidth: CGFloat, maxFontSize: CGFloat, font: UIFont) -> CGFloat {
    var variableFont = font.withSize(maxFontSize)
    var currentWidth = self.size(withAttributes: [NSAttributedString.Key.font:variableFont]).width

    while currentWidth > targetWidth {
        variableFont = variableFont.withSize(variableFont.pointSize - 1)
        currentWidth = self.size(withAttributes: [NSAttributedString.Key.font:variableFont]).width
    }

    return variableFont.pointSize
}

And it would be used like this:

textView.font = textView.font!.withSize(textView.text!.fontSizeThatFits(targetWidth: view.frame.width, maxFontSize: 50, font: textView.font!))

Here is class structure of UIDevice

+ (UIDevice *)currentDevice;

@property(nonatomic,readonly,strong) NSString    *name;              // e.g. "My iPhone"
@property(nonatomic,readonly,strong) NSString    *model;             // e.g. @"iPhone", @"iPod touch"
@property(nonatomic,readonly,strong) NSString    *localizedModel;    // localized version of model
@property(nonatomic,readonly,strong) NSString    *systemName;        // e.g. @"iOS"
@property(nonatomic,readonly,strong) NSString    *systemVersion;

For Swift

Create UITextField Extension

extension UITextField{

    func setPlaceHolderColor(){
        self.attributedPlaceholder = NSAttributedString(string: self.placeholder!, attributes: [NSForegroundColorAttributeName : UIColor.white])
    }
}

If Are you set from storyboard.

extension UITextField{
    @IBInspectable var placeHolderColor: UIColor? {
        get {
            return self.placeHolderColor
        }
        set {
            self.attributedPlaceholder = NSAttributedString(string:self.placeholder != nil ? self.placeholder! : "", attributes:[NSAttributedString.Key.foregroundColor : newValue!])
        }
    }
}

They are related values, and kept consistent by the property setter/getter methods (and using the fact that frame is a purely synthesized value, not backed by an actual instance variable).

The main equations are:

frame.origin = center - bounds.size / 2

(which is the same as)

center = frame.origin + bounds.size / 2

(and there’s also)

frame.size = bounds.size

That's not code, just equations to express the invariant between the three properties. These equations also assume your view's transform is the identity, which it is by default. If it's not, then bounds and center keep the same meaning, but frame can change. Unless you're doing non-right-angle rotations, the frame will always be the transformed view in terms of the superview's coordinates.

This stuff is all explained in more detail with a useful mini-library here:

http://bynomial.com/blog/?p=24

I reviewed all the answers and all are keeping fixed width and adjust only height. If you wish to adjust also width you can very easily use this method:

so when configuring your text view, set scroll disabled

textView.isScrollEnabled = false

and then in delegate method func textViewDidChange(_ textView: UITextView) add this code:

func textViewDidChange(_ textView: UITextView) {
    let newSize = textView.sizeThatFits(CGSize(width: CGFloat.greatestFiniteMagnitude, height: CGFloat.greatestFiniteMagnitude))
    textView.frame = CGRect(origin: textView.frame.origin, size: newSize)
}

Outputs:

//You could place this code into viewDidLoad
- (void)viewDidLoad
{
    [super viewDidLoad];
    self.navigationController.navigationBar.tintColor = [UIColor redColor];
    //change the nav bar colour
    self.navigationController.view.backgroundColor = [UIColor redColor];
    //change the background colour
    self.navigationController.navigationBar.translucent = NO;
 }   
//Or you can place it into viewDidAppear
- (void)viewDidAppear:(BOOL)animated
{
    [super viewDidAppear:(BOOL)animated];
    self.navigationController.navigationBar.tintColor = [UIColor redColor];
    //change the nav bar colour
    self.navigationController.view.backgroundColor = [UIColor redColor];
    //change the background colour
    self.navigationController.navigationBar.translucent = NO;
}

This answer has been updated to Swift 3

I always think it is nice to have a very simple, self-contained example so that nothing is assumed when I am learning a new task. This answer is that for deleting UITableView rows. The project performs like this:

This project is based on the UITableView example for Swift.

Add the Code

Create a new project and replace the ViewController.swift code with the following.

import UIKit
class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {

    // These strings will be the data for the table view cells
    var animals: [String] = ["Horse", "Cow", "Camel", "Pig", "Sheep", "Goat"]

    let cellReuseIdentifier = "cell"

    @IBOutlet var tableView: UITableView!

    override func viewDidLoad() {
        super.viewDidLoad()

        // It is possible to do the following three things in the Interface Builder
        // rather than in code if you prefer.
        self.tableView.register(UITableViewCell.self, forCellReuseIdentifier: cellReuseIdentifier)
        tableView.delegate = self
        tableView.dataSource = self
    }

    // number of rows in table view
    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return self.animals.count
    }

    // create a cell for each table view row
    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

        let cell:UITableViewCell = self.tableView.dequeueReusableCell(withIdentifier: cellReuseIdentifier) as UITableViewCell!

        cell.textLabel?.text = self.animals[indexPath.row]

        return cell
    }

    // method to run when table view cell is tapped
    func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
        print("You tapped cell number \(indexPath.row).")
    }

    // this method handles row deletion
    func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath) {

        if editingStyle == .delete {

            // remove the item from the data model
            animals.remove(at: indexPath.row)

            // delete the table view row
            tableView.deleteRows(at: [indexPath], with: .fade)

        } else if editingStyle == .insert {
            // Not used in our example, but if you were adding a new row, this is where you would do it.
        }
    }

}

The single key method in the code above that enables row deletion is the last one. Here it is again for emphasis:

// this method handles row deletion
func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath) {

    if editingStyle == .delete {

        // remove the item from the data model
        animals.remove(at: indexPath.row)

        // delete the table view row
        tableView.deleteRows(at: [indexPath], with: .fade)

    } else if editingStyle == .insert {
        // Not used in our example, but if you were adding a new row, this is where you would do it.
    }
}

Storyboard

Add a UITableView to the View Controller in the storyboard. Use auto layout to pin the four sides of the table view to the edges of the View Controller. Control drag from the table view in the storyboard to the @IBOutlet var tableView: UITableView! line in the code.

Finished

That's all. You should be able to run your app now and delete rows by swiping left and tapping "Delete".

Variations

Change the "Delete" button text

Add the following method:

func tableView(_ tableView: UITableView, titleForDeleteConfirmationButtonForRowAt indexPath: IndexPath) -> String? {
    return "Erase"
}

Custom button actions

Add the following method.

func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]? {

    // action one
    let editAction = UITableViewRowAction(style: .default, title: "Edit", handler: { (action, indexPath) in
        print("Edit tapped")
    })
    editAction.backgroundColor = UIColor.blue

    // action two
    let deleteAction = UITableViewRowAction(style: .default, title: "Delete", handler: { (action, indexPath) in
        print("Delete tapped")
    })
    deleteAction.backgroundColor = UIColor.red

    return [editAction, deleteAction]
}

Note that this is only available from iOS 8. See this answer for more details.

Updated for iOS 11

Actions can be placed either leading or trailing the cell using methods added to the UITableViewDelegate API in iOS 11.

func tableView(_ tableView: UITableView,
                leadingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration?
 {
     let editAction = UIContextualAction(style: .normal, title:  "Edit", handler: { (ac:UIContextualAction, view:UIView, success:(Bool) -> Void) in
             success(true)
         })
editAction.backgroundColor = .blue

         return UISwipeActionsConfiguration(actions: [editAction])
 }

 func tableView(_ tableView: UITableView,
                trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration?
 {
     let deleteAction = UIContextualAction(style: .normal, title:  "Delete", handler: { (ac:UIContextualAction, view:UIView, success:(Bool) -> Void) in
         success(true)
     })
     deleteAction.backgroundColor = .red

     return UISwipeActionsConfiguration(actions: [deleteAction])
 }

I had a simmilar problem, but all the suggestions didn't help.

However, the problem was the *.png itself. It had no alpha channel. Somehow Xcode ignores all png files without alpha channel during the deploy process.

Here i have updated for swift 3

applicationFrame deprecated from iOS 9

In swift three they have removed () and they have changed few naming convention, you can refer here Link

func windowHeight() -> CGFloat {
    return UIScreen.main.bounds.size.height
}

func windowWidth() -> CGFloat {
    return UIScreen.main.bounds.size.width
}

Answers here tell you how to achieve multiline button title programmatically.

I just wanted to add that if you are using storyboards, you can type [Ctrl+Enter] to force a newline on a button title field.

HTH

In Swift 3, you can simply use CGPoint.zero or CGRect.zero in place of CGRectZero or CGPointZero.

However, in Swift 4, CGRect.zero and 'CGPoint.zero' will work

I write code bewlow. It works well in product version. Supprot Swift 4.2 +

extension UIButton{
 enum ImageTitleRelativeLocation {
    case imageUpTitleDown
    case imageDownTitleUp
    case imageLeftTitleRight
    case imageRightTitleLeft
}
 func centerContentRelativeLocation(_ relativeLocation: 
                                      ImageTitleRelativeLocation,
                                   spacing: CGFloat = 0) {
    assert(contentVerticalAlignment == .center,
           "only works with contentVerticalAlignment = .center !!!")

    guard (title(for: .normal) != nil) || (attributedTitle(for: .normal) != nil) else {
        assert(false, "TITLE IS NIL! SET TITTLE FIRST!")
        return
    }

    guard let imageSize = self.currentImage?.size else {
        assert(false, "IMGAGE IS NIL! SET IMAGE FIRST!!!")
        return
    }
    guard let titleSize = titleLabel?
        .systemLayoutSizeFitting(UIView.layoutFittingCompressedSize) else {
            assert(false, "TITLELABEL IS NIL!")
            return
    }

    let horizontalResistent: CGFloat
    // extend contenArea in case of title is shrink
    if frame.width < titleSize.width + imageSize.width {
        horizontalResistent = titleSize.width + imageSize.width - frame.width
        print("horizontalResistent", horizontalResistent)
    } else {
        horizontalResistent = 0
    }

    var adjustImageEdgeInsets: UIEdgeInsets = .zero
    var adjustTitleEdgeInsets: UIEdgeInsets = .zero
    var adjustContentEdgeInsets: UIEdgeInsets = .zero

    let verticalImageAbsOffset = abs((titleSize.height + spacing) / 2)
    let verticalTitleAbsOffset = abs((imageSize.height + spacing) / 2)

    switch relativeLocation {
    case .imageUpTitleDown:

        adjustImageEdgeInsets.top = -verticalImageAbsOffset
        adjustImageEdgeInsets.bottom = verticalImageAbsOffset
        adjustImageEdgeInsets.left = titleSize.width / 2 + horizontalResistent / 2
        adjustImageEdgeInsets.right = -titleSize.width / 2 - horizontalResistent / 2

        adjustTitleEdgeInsets.top = verticalTitleAbsOffset
        adjustTitleEdgeInsets.bottom = -verticalTitleAbsOffset
        adjustTitleEdgeInsets.left = -imageSize.width / 2 + horizontalResistent / 2
        adjustTitleEdgeInsets.right = imageSize.width / 2 - horizontalResistent / 2

        adjustContentEdgeInsets.top = spacing
        adjustContentEdgeInsets.bottom = spacing
        adjustContentEdgeInsets.left = -horizontalResistent
        adjustContentEdgeInsets.right = -horizontalResistent
    case .imageDownTitleUp:
        adjustImageEdgeInsets.top = verticalImageAbsOffset
        adjustImageEdgeInsets.bottom = -verticalImageAbsOffset
        adjustImageEdgeInsets.left = titleSize.width / 2 + horizontalResistent / 2
        adjustImageEdgeInsets.right = -titleSize.width / 2 - horizontalResistent / 2

        adjustTitleEdgeInsets.top = -verticalTitleAbsOffset
        adjustTitleEdgeInsets.bottom = verticalTitleAbsOffset
        adjustTitleEdgeInsets.left = -imageSize.width / 2 + horizontalResistent / 2
        adjustTitleEdgeInsets.right = imageSize.width / 2 - horizontalResistent / 2

        adjustContentEdgeInsets.top = spacing
        adjustContentEdgeInsets.bottom = spacing
        adjustContentEdgeInsets.left = -horizontalResistent
        adjustContentEdgeInsets.right = -horizontalResistent
    case .imageLeftTitleRight:
        adjustImageEdgeInsets.left = -spacing / 2
        adjustImageEdgeInsets.right = spacing / 2

        adjustTitleEdgeInsets.left = spacing / 2
        adjustTitleEdgeInsets.right = -spacing / 2

        adjustContentEdgeInsets.left = spacing
        adjustContentEdgeInsets.right = spacing
    case .imageRightTitleLeft:
        adjustImageEdgeInsets.left = titleSize.width + spacing / 2
        adjustImageEdgeInsets.right = -titleSize.width - spacing / 2

        adjustTitleEdgeInsets.left = -imageSize.width - spacing / 2
        adjustTitleEdgeInsets.right = imageSize.width + spacing / 2

        adjustContentEdgeInsets.left = spacing
        adjustContentEdgeInsets.right = spacing
    }

    imageEdgeInsets = adjustImageEdgeInsets
    titleEdgeInsets = adjustTitleEdgeInsets
    contentEdgeInsets = adjustContentEdgeInsets

    setNeedsLayout()
}
}

Here is a solution using UIPageViewControllerDataSource methods:

The code keeps track of the current displayed view controller in the UIPageViewController.

...
@property (nonatomic, strong) UIViewController *currentViewController;
@property (nonatomic, strong) UIViewController *nextViewController;
...

First initialize currentViewController to the initial view controller set for the UIPageViewController.

- (void) viewDidLoad {
    [super viewDidLoad];
    ...
    self.currentViewController = self.viewControllers[0];
    ...
    [self.pageViewController setViewControllers: @[self.currentViewController] direction: dir animated: YES completion: nil];
}

Then keep track of currentViewController in the UIPageViewControllerDelegate methods: pageViewController: willTransitionToViewControllers: and pageViewController:didFinishAnimating:previousViewControllers:transitionCompleted:.

- (nullable UIViewController *) pageViewController: (UIPageViewController *) pageViewController viewControllerBeforeViewController: (UIViewController *) viewController {
    NSInteger idx = [self.viewControllers indexOfObject: viewController];
    if (idx > 0) {
        return self.viewControllers[idx - 1];
    } else {
        return nil;
    }
}

- (nullable UIViewController *) pageViewController:(UIPageViewController *)pageViewController viewControllerAfterViewController: (UIViewController *) viewController {
    NSInteger idx = [self.viewControllers indexOfObject: viewController];
    if (idx == NSNotFound) {
        return nil;
    } else {
        if (idx + 1 < self.viewControllers.count) {
            return self.viewControllers[idx + 1];
        } else {
            return nil;
        }
    }
}

- (void) pageViewController:(UIPageViewController *)pageViewController willTransitionToViewControllers:(NSArray<UIViewController *> *)pendingViewControllers {
    self.nextViewController = [pendingViewControllers firstObject];
}

- (void)pageViewController:(UIPageViewController *)pageViewController didFinishAnimating:(BOOL)finished previousViewControllers:(NSArray<UIViewController *> *)previousViewControllers transitionCompleted:(BOOL)completed {
    if (completed) {
        self.currentViewController = self.nextViewController;
    }
}

Finally, in the method of your choice (in the example below it's - (IBAction) onNext: (id) sender), you can programmatically switch to the next or previous controller using UIPageViewControllerDataSouce methods pageViewController:viewControllerBeforeViewController: , pageViewController:viewControllerAfterViewController: to get the next or prev view controller and navigate to it by calling [self.pageViewController setViewControllers: @[vc] direction: UIPageViewControllerNavigationDirectionForward animated: YES completion: nil];

- (void) onNext {
    UIViewController *vc = [self pageViewController: self.tutorialViewController viewControllerAfterViewController: self.currentViewController];
    if (vc != nil) {
        self.currentViewController = vc;
        [self.tutorialViewController setViewControllers: @[vc] direction: UIPageViewControllerNavigationDirectionForward animated: YES completion: nil];
    }
}

This is one line of code to get the UILabel Height using Objective-c:

labelObj.numberOfLines = 0;
CGSize neededSize = [labelObj sizeThatFits:CGSizeMake(screenWidth, CGFLOAT_MAX)];

and using .height you will get the height of label as follows:

neededSize.height

Try this code:--

UIImageView *imv = [[UIImageView alloc]initWithFrame:CGRectMake(3,2, 20, 25)];
imv.image=[UIImage imageNamed:@"arrow2.png"];
[cell addSubview:imv];
[imv release];

For adding margins to specified cells, you can use this custom flow layout. https://github.com/voyages-sncf-technologies/VSCollectionViewCellInsetFlowLayout/

extension ViewController : VSCollectionViewDelegateCellInsetFlowLayout 
{
    func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, insetForItemAt indexPath: IndexPath) -> UIEdgeInsets {
        if indexPath.item == 0 {
            return UIEdgeInsets(top: 0, left: 0, bottom: 10, right: 0)
        }
        return UIEdgeInsets.zero
    }

You can use UITapGestureRecongnizer method for dismissing keyboard by clicking outside of UITextField. By using this method whenever user will click outside of UITextField then keyboard will get dismiss. Below is the code snippet for using it.

 UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc]
                                   initWithTarget:self
                                   action:@selector(dismissk)];

    [self.view addGestureRecognizer:tap];


//Method
- (void) dismissk
{
    [abctextfield resignFirstResponder];
    [deftextfield resignFirstResponder];

}

I had the same problem. Just set the ContentMode of the ImageView that is inside the UIButton.

[[self.itemImageButton imageView] setContentMode: UIViewContentModeScaleAspectFit];
[self.itemImageButton setImage:[UIImage imageNamed:stretchImage] forState:UIControlStateNormal];

Hope this helps.

If your viewController is under UINavigationController.

Subclass UINavigationController and add

override var preferredStatusBarStyle: UIStatusBarStyle {
    return topViewController?.preferredStatusBarStyle ?? .default
}

ViewController's preferredStatusBarStyle will be called.

I would NOT use mach_absolute_time() because it queries a combination of the kernel and the processor for an absolute time using ticks (probably an uptime).

What I would use:

CFAbsoluteTimeGetCurrent();

This function is optimized to correct the difference in the iOS and OSX software and hardware.

Something Geekier

The quotient of a difference in mach_absolute_time() and AFAbsoluteTimeGetCurrent() is always around 24000011.154871

Here is a log of my app:

Please note that final result time is a difference in CFAbsoluteTimeGetCurrent()'s

Here's something I came up with after applying a few principles other SO posts, including Aaron's link:

AnnotationPin *myAnnotation = (AnnotationPin *)annotation;

self = [super initWithAnnotation:myAnnotation reuseIdentifier:reuseIdentifier];
self.backgroundColor = [UIColor greenColor];
self.frame = CGRectMake(0,0,30,30);
imageView = [[UIImageView alloc] initWithImage:myAnnotation.THEIMAGE];
imageView.frame = CGRectMake(3,3,20,20);
imageView.layer.masksToBounds = NO;
[self addSubview:imageView];
[imageView release];

CGSize titleSize = [myAnnotation.THETEXT sizeWithFont:[UIFont systemFontOfSize:12]];
CGRect newFrame = self.frame;
newFrame.size.height = titleSize.height + 12;
newFrame.size.width = titleSize.width + 32;
self.frame = newFrame;
self.layer.borderColor = [UIColor colorWithRed:0 green:.3 blue:0 alpha:1.0f].CGColor;
self.layer.borderWidth = 3.0;
        
UILabel *infoLabel = [[UILabel alloc] initWithFrame:CGRectMake(26,5,newFrame.size.width-32,newFrame.size.height-12)];
infoLabel.text = myAnnotation.title;
infoLabel.backgroundColor = [UIColor clearColor];
infoLabel.textColor = [UIColor blackColor];
infoLabel.textAlignment = UITextAlignmentCenter;
infoLabel.font = [UIFont systemFontOfSize:12];

[self addSubview:infoLabel];
[infoLabel release];

In this example, I'm adding a custom pin to a MKAnnotation class that resizes a UILabel according to the text size. It also adds an image on the left side of the view, so you see some of the code managing the proper spacing to handle the image and padding.

The key is to use CGSize titleSize = [myAnnotation.THETEXT sizeWithFont:[UIFont systemFontOfSize:12]]; and then redefine the view's dimensions. You can apply this logic to any view.

Although Aaron's answer works for some, it didn't work for me. This is a far more detailed explanation that you should try immediately before going anywhere else if you want a more dynamic view with an image and resizable UILabel. I already did all the work for you!!

Whenever I attempt to remove the constraints that the system had to break, my constraints are no longer enough to satisfy the IB (ie "missing constraints" shows in the IB, which means they're incomplete and won't be used). I actually got around this by setting the constraint it wants to break to low priority, which (and this is an assumption) allows the system to break the constraint gracefully. It's probably not the best solution, but it solved my problem and the resulting constraints worked perfectly.

On Xcode Version 8.1 (8B62) it can be done directly in Attributes Inspector. Select the textField and then choose the appropriate option from Clear Button drop down box, which is located in Attributes Inspector.

A concise yet comprehensive solution in Swift 4.2, takes into account UINavigationControllers, UITabBarControllers, presented and child view controllers:

extension UIViewController {
  func topmostViewController() -> UIViewController {
    if let navigationVC = self as? UINavigationController,
      let topVC = navigationVC.topViewController {
      return topVC.topmostViewController()
    }
    if let tabBarVC = self as? UITabBarController,
      let selectedVC = tabBarVC.selectedViewController {
      return selectedVC.topmostViewController()
    }
    if let presentedVC = presentedViewController {
      return presentedVC.topmostViewController()
    }
    if let childVC = children.last {
      return childVC.topmostViewController()
    }
    return self
  }
}

extension UIApplication {
  func topmostViewController() -> UIViewController? {
    return keyWindow?.rootViewController?.topmostViewController()
  }
}

Usage:

let viewController = UIApplication.shared.topmostViewController()

I actually think it may retain cached information when you close out the UIWebView. I've tried removing a UIWebView from my UIViewController, releasing it, then creating a new one. The new one remembered exactly where I was at when I went back to an address without having to reload everything (it remembered my previous UIWebView was logged in).

So a couple of suggestions:

[[NSURLCache sharedURLCache] removeCachedResponseForRequest:NSURLRequest];

This would remove a cached response for a specific request. There is also a call that will remove all cached responses for all requests ran on the UIWebView:

[[NSURLCache sharedURLCache] removeAllCachedResponses];

After that, you can try deleting any associated cookies with the UIWebView:

for(NSHTTPCookie *cookie in [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies]) {

    if([[cookie domain] isEqualToString:someNSStringUrlDomain]) {

        [[NSHTTPCookieStorage sharedHTTPCookieStorage] deleteCookie:cookie];
    }
}

Swift 3:

// Remove all cache 
URLCache.shared.removeAllCachedResponses()

// Delete any associated cookies     
if let cookies = HTTPCookieStorage.shared.cookies {
    for cookie in cookies {
        HTTPCookieStorage.shared.deleteCookie(cookie)
    }
}

Sometimes we developer stuck in small designing part of any UI screen. One of the most irritating requirement is under line text. Don’t worry here is the solution.

Underlining a text in a UILabel using Objective C

UILabel *label=[[UILabel alloc]initWithFrame:CGRectMake(0, 0, 320, 480)];
label.backgroundColor=[UIColor lightGrayColor];
NSMutableAttributedString *attributedString;
attributedString = [[NSMutableAttributedString alloc] initWithString:@"Apply Underlining"];
[attributedString addAttribute:NSUnderlineStyleAttributeName value:@1 range:NSMakeRange(0,
[attributedString length])];
[label setAttributedText:attributedString];

Underlining a text in UILabel using Swift

 label.backgroundColor = .lightGray
 let attributedString = NSMutableAttributedString.init(string: "Apply UnderLining")
 attributedString.addAttribute(NSUnderlineStyleAttributeName, value: 1, range:
NSRange.init(location: 0, length: attributedString.length))
 label.attributedText = attributedString

Tested with Xcode 14.

For hiding any section header, Return nil for title of section delegate

func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
    return nil
}

I'm using a UIWebView that isn't a subview (and thus isn't part of the window hierarchy) to determine the sizes of HTML content for UITableViewCells. I found that the disconnected UIWebView doesn't report its size properly with -[UIWebView sizeThatFits:]. Additionally, as mentioned in https://stackoverflow.com/a/3937599/9636, you must set the UIWebView's frame height to 1 in order to get the proper height at all.

If the UIWebView's height is too big (i.e. you have it set to 1000, but the HTML content size is only 500):

UIWebView.scrollView.contentSize.height
-[UIWebView stringByEvaluatingJavaScriptFromString:@"document.height"]
-[UIWebView sizeThatFits:]

All return a height of 1000.

To solve my problem in this case, I used https://stackoverflow.com/a/11770883/9636, which I dutifully voted up. However, I only use this solution when my UIWebView.frame.width is the same as the -[UIWebView sizeThatFits:] width.

Using modern UIGraphicsImageRenderer

public extension UIView {
    @available(iOS 10.0, *)
    public func renderToImage(afterScreenUpdates: Bool = false) -> UIImage {
        let rendererFormat = UIGraphicsImageRendererFormat.default()
        rendererFormat.opaque = isOpaque
        let renderer = UIGraphicsImageRenderer(size: bounds.size, format: rendererFormat)

        let snapshotImage = renderer.image { _ in
            drawHierarchy(in: bounds, afterScreenUpdates: afterScreenUpdates)
        }
        return snapshotImage
    }
}

Here is a Swift way to get screen status bar height:

var screenStatusBarHeight: CGFloat {
    return UIApplication.sharedApplication().statusBarFrame.height
}

These are included as a standard function in a project of mine: https://github.com/goktugyil/EZSwiftExtensions

If you want to call them like that, you should declare them static.

I was getting the same fav icon error - 404 (Not Found). I used the following element in the <head> element of my index.html file and it fixed the error:

<link rel="icon" href="data:;base64,iVBORw0KGgo=">

Alternatives:

>>> map(a.__getitem__, b)
[1, 5, 5]

>>> import operator
>>> operator.itemgetter(*b)(a)
(1, 5, 5)

You can access sequence elements with arr.0 arr.1 and so on. See The Django template system chapter of the django book for more information.

This works for me

$('.someclass').click(function() {
    $varName = $(this).data('fulltext');
    console.log($varName);
});

• int to Hex :

  Integer.toHexString(intValue);
  

• Hex to int :

  Integer.valueOf(hexString, 16).intValue();
  

You may also want to use long instead of int (if the value does not fit the int bounds):

• Hex to long:

  Long.valueOf(hexString, 16).longValue()
  

• long to Hex

  Long.toHexString(longValue)
  

Following are the steps to remove mapping of a project from TFS:

(1) Click on View Button.

(2) Open Team Explorer

(3) Click on Source Control

(4) Right click on your project/Directory

(5) Click on Remove Mapping

(6) Finally Delete the Project form local directory.

I took it from Deborahk and modified it a little bit.

One more cause for the "secret key not available" message: GPG version mismatch.

Practical example: I had been using GPG v1.4. Switching packaging systems, the MacPorts supplied gpg was removed, and revealed another gpg binary in the path, this one version 2.0. For decryption, it was unable to locate the secret key and gave this very error. For encryption, it complained about an unusable public key. However, gpg -k and -K both listed valid keys, which was the cause of major confusion.

We need to implement two layouts. One to hold listview and another to hold row item of listview. Implement your own custom adapter. Idea is to include one textview and one imageview.

public View getView(int position, View convertView, ViewGroup parent) {
 // TODO Auto-generated method stub
 LayoutInflater inflater = (LayoutInflater) context
 .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
 View single_row = inflater.inflate(R.layout.list_row, null,
 true);
 TextView textView = (TextView) single_row.findViewById(R.id.textView);
 ImageView imageView = (ImageView) single_row.findViewById(R.id.imageView);
 textView.setText(color_names[position]);
 imageView.setImageResource(image_id[position]);
 return single_row; 
 }

Next we implement functionality in main activity to include images and text data dynamically during runtime. You can pass dynamically created text array and image id array to the constructor of custom adapter.

Customlistadapter adapter = new Customlistadapter(this, image_id, text_name);

hmm, well here's a workaround anyway:

function JSON_stringify(s, emit_unicode)
{
   var json = JSON.stringify(s);
   return emit_unicode ? json : json.replace(/[\u007f-\uffff]/g,
      function(c) { 
        return '\\u'+('0000'+c.charCodeAt(0).toString(16)).slice(-4);
      }
   );
}

test case:

js>s='15\u00f8C 3\u0111';
15°C 3?
js>JSON_stringify(s, true)
"15°C 3?"
js>JSON_stringify(s, false)
"15\u00f8C 3\u0111"

@Victor's answer worked for me and reposting it here in Kotlin in case useful to someone else doing Android.

if (list!!.isNotEmpty()) {
   Collections.sort(
     list,
     Comparator { c1, c2 -> //You should ensure that list doesn't contain null values!
     c1.name!!.compareTo(c2.name!!)
   })
}

Edit: thought of something else.

You say you're creating a form dynamically - do you really mean a <form> and its contents 'cause asp.net takes issue with multiple forms on a page and it's already creating one uberform for you.

Ok, so this piece of code should work for you. I changed the names to match your parameter.

inFile.seekg(0, ios::end);  
if (inFile.tellg() == 0) {    
  // ...do something with empty file...  
}

I use this code, it works nice

html, body {
  height: 100%;
  width: 100%;
  padding: 0;
  margin: 0;
  background: black url(back2.png) center center no-repeat;;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
}

Are you using an error handler? If you're ignoring errors and try to name a sheet the same as an existing sheet or a name with invalid characters, it could be just skipping over that line. See the CleanSheetName function here

http://www.dailydoseofexcel.com/archives/2005/01/04/naming-a-sheet-based-on-a-cell/

for a list of invalid characters that you may want to check for.

Update

Other things to try: Fully qualified references, throwing in a Doevents, code cleaning. This code qualifies your Sheets reference to ThisWorkbook (you can change it to ActiveWorkbook if that suits). It also adds a thousand DoEvents (stupid overkill, but if something's taking a while to get done, this will allow it to - you may only need one DoEvents if this actually fixes anything).

Dim WS As Worksheet
Dim i As Long

With ThisWorkbook
    Set WS = .Worksheets.Add(After:=.Sheets(.Sheets.Count))
End With

For i = 1 To 1000
    DoEvents
Next i

WS.Name = txtSheetName.Value

Finally, whenever I have a goofy VBA problem that just doesn't make sense, I use Rob Bovey's CodeCleaner. It's an add-in that exports all of your modules to text files then re-imports them. You can do it manually too. This process cleans out any corrupted p-code that's hanging around.

Create a Virtual Machine with Windows running on it and download the file to a shared folder. :-D

function SingletonClass() 
{
    // demo variable
    var names = [];

    // instance of the singleton
    this.singletonInstance = null;

    // Get the instance of the SingletonClass
    // If there is no instance in this.singletonInstance, instanciate one
    var getInstance = function() {
        if (!this.singletonInstance) {
            // create a instance
            this.singletonInstance = createInstance();
        }

        // return the instance of the singletonClass
        return this.singletonInstance;
    }

    // function for the creation of the SingletonClass class
    var createInstance = function() {

        // public methodes
        return {
            add : function(name) {
                names.push(name);
            },
            names : function() {
                return names;
            }
        }
    }

    // wen constructed the getInstance is automaticly called and return the SingletonClass instance 
    return getInstance();
}

var obj1 = new SingletonClass();
obj1.add("Jim");
console.log(obj1.names());
// prints: ["Jim"]

var obj2 = new SingletonClass();
obj2.add("Ralph");
console.log(obj1.names());
// Ralph is added to the singleton instance and there for also acceseble by obj1
// prints: ["Jim", "Ralph"]
console.log(obj2.names());
// prints: ["Jim", "Ralph"]

obj1.add("Bart");
console.log(obj2.names());
// prints: ["Jim", "Ralph", "Bart"]

Use the string concatenation operator:

Dim str As String = New String("") & "some other string"

Strings in .NET are immutable and thus there exist no concept of appending strings. All string modifications causes a new string to be created and returned.

This obviously cause a terrible performance. In common everyday code this isn't an issue, but if you're doing intensive string operations in which time is of the essence then you will benefit from looking into the StringBuilder class. It allow you to queue appends. Once you're done appending you can ask it to actually perform all the queued operations.

See "How to: Concatenate Multiple Strings" for more information on both methods.

Option #1

Instead of picking the binary/raw data into a variable and then writing, you can use CURLOPT_FILE option to directly show a file to the curl for the downloading.

Here is the function:

// takes URL of image and Path for the image as parameter
function download_image1($image_url, $image_file){
    $fp = fopen ($image_file, 'w+');              // open file handle

    $ch = curl_init($image_url);
    // curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); // enable if you want
    curl_setopt($ch, CURLOPT_FILE, $fp);          // output to file
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
    curl_setopt($ch, CURLOPT_TIMEOUT, 1000);      // some large value to allow curl to run for a long time
    curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0');
    // curl_setopt($ch, CURLOPT_VERBOSE, true);   // Enable this line to see debug prints
    curl_exec($ch);

    curl_close($ch);                              // closing curl handle
    fclose($fp);                                  // closing file handle
}

And here is how you should call it:

// test the download function
download_image1("http://www.gravatar.com/avatar/10773ae6687b55736e171c038b4228d2", "local_image1.jpg");

Option #2

Now, If you want to download a very large file, that case above function may not become handy. You can use the below function this time for handling a big file. Also, you can print progress(in % or in any other format) if you want. Below function is implemented using a callback function that writes a chunk of data in to the file in to the progress of downloading.

// takes URL of image and Path for the image as parameter
function download_image2($image_url){
    $ch = curl_init($image_url);
    // curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); // enable if you want
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
    curl_setopt($ch, CURLOPT_TIMEOUT, 1000);      // some large value to allow curl to run for a long time
    curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0');
    curl_setopt($ch, CURLOPT_WRITEFUNCTION, "curl_callback");
    // curl_setopt($ch, CURLOPT_VERBOSE, true);   // Enable this line to see debug prints
    curl_exec($ch);

    curl_close($ch);                              // closing curl handle
}

/** callback function for curl */
function curl_callback($ch, $bytes){
    global $fp;
    $len = fwrite($fp, $bytes);
    // if you want, you can use any progress printing here
    return $len;
}

And here is how to call this function:

// test the download function
$image_file = "local_image2.jpg";
$fp = fopen ($image_file, 'w+');              // open file handle
download_image2("http://www.gravatar.com/avatar/10773ae6687b55736e171c038b4228d2");
fclose($fp);                                  // closing file handle

I don't believe that you can achieve this functionality with standard <select> element.

What i would suggest is to use such way.

The basic version of it won't take too much space and you can easily bind mouseover events to sub items to show a nice tooltip.

Hope this helps, Sinan.

I was running Vagrant with VirtualBox 5.1.X, and had to downgrade to VirtualBox 5.0.40, and install the vbguest plugin to solve this problem.

My steps were:

• Uninstall VirtualBox 5.1.X
• Install Vagrant 5.0.40
• Reboot my machine
• Run vagrant up for my vagrant. It'll fail.
• Run vagrant plugin install vagrant-vbguest while my VM is running, to install the vagrant plugin. This manages syncing VirtualBox Guest versions between host and guest.
• Run vagrant reload to reload my virtual machine
• Magic!

Replace double quotes with single ones:

INSERT
INTO    MY.LOGFILE
        (id,severity,category,logdate,appendername,message,extrainfo)
VALUES  (
       'dee205e29ec34',
       'FATAL',
       'facade.uploader.model',
       '2013-06-11 17:16:31',
       'LOGDB',
       NULL,
       NULL
       )

In SQL, double quotes are used to mark identifiers, not string constants.

I solved that problem. In my case when i did “git clone” in one directory of my choice without do “git init” inside of that repository. Then I moved in to the cloned repository, where already have a “.git” (is a git repository i.e. do not need a “git init”) and finally I started do my changes or anything.

It probably doesn’t solve the problem but shows you how to avoid it.

The command git clone should be a “cd” command imbued if no submodule exists.

A great search engine for special characters that I recenetly found: amp-what?

You can even search by object name, like "arrow", "chess", etc...

You can use arguments with default values.

def someMethod(def mandatory,def optional=null){}

if argument "optional" not exist, it turns to "null".

As @Rajib pointed out, You can't access your env variables using config('myVariable')

1. You have to add the variable to .env file first.
2. Add the variable to some config file in config directory. I usually add to config/app.php
3. Once done, will access them like Config::get('fileWhichContainsVariable.Variable'); using the Config Facade

Probably You will have to clear config cache using php artisan config:clear AND you will also have to restart server.

This solved my problem : Sample alter table statement to change the ownership.

ALTER TABLE databasechangelog OWNER TO arwin_ash;
ALTER TABLE databasechangeloglock OWNER TO arwin_ash;

I suggest you use http-request, so that even redirects are managed.

var http = require('http-request');
var options = {url: 'http://localhost/foo.pdf'};
http.get(options, '/path/to/foo.pdf', function (error, result) {
    if (error) {
        console.error(error);
    } else {
        console.log('File downloaded at: ' + result.file);
    }
});

If you use Iclick pluging, it is as simply as you see below.

 $('#radio1').iCheck('uncheck');

Try with <button type="submit"> you can perform the functionality of submitform() by doing <form ....... onsubmit="submitform()">

In your references click on the EntitiyFramework . Go to properties and set the specific version to False. It worked for me.

Use the setting log4j.appender.FILE.RollingPolicy.FileNamePattern, e.g. log4j.appender.FILE.RollingPolicy.FileNamePattern=F:/logs/filename.log.%d{dd}.gz for keeping logs one month before rolling over.

I didn't wait for one month to check but I tried with mm (i.e. minutes) and confirmed it overwrites, so I am assuming it will work for all patterns.

It's a very late answer but I resolved the issue turning off the lazy loading:

db.Configuration.LazyLoadingEnabled = false;

Once I packed JS code doing that to a tiny library:

https://github.com/AlexLibs/client-side-csv-generator

The Code, Documentation and Demo/Playground are provided on Github.

Enjoy :)

Pull requests are welcome.

If we are using TypeScript, we can update the type definition file by running the command npm install @types/node from the terminal or command prompt.

<div *ngIf="currentStatus !== ('status1' || 'status2' || 'status3' || 'status4')">

if you use Bootstrap 2.2.1 then maybe is this what you are looking for.

Use utcOffset function.

var testDateUtc = moment.utc("2015-01-30 10:00:00");
var localDate = moment(testDateUtc).utcOffset(10 * 60); //set timezone offset in minutes
console.log(localDate.format()); //2015-01-30T20:00:00+10:00

You can use Collections.sort(list) to sort list if your list contains Comparable elements. Otherwise I would recommend you to implement that interface like here:

public class Circle implements Comparable<Circle> {}

and of course provide your own realization of compareTo method like here:

@Override
    public int compareTo(Circle another) {
        if (this.getD()<another.getD()){
            return -1;
        }else{
            return 1;
        }
    }

And then you can again use Colection.sort(list) as now list contains objects of Comparable type and can be sorted. Order depends on compareTo method. Check this https://docs.oracle.com/javase/tutorial/collections/interfaces/order.html for more detailed information.

I was facing the same problem. This way I was able to solved it. As CQM said, using Color.parseColor() is a good solution to this issue.

Here is the code I used:

this.Button_C.setTextColor(Color.parseColor(prefs.getString("color_prefs", String.valueOf(R.color.green))));

In this case my target was to change the Button's text color (Button_C) when I change the color selection from my Preferences (color_prefs).

I ended up with this:

if($.browser.msie || $.browser.webkit){
  // doesn't work with opera and FF
  $(this).after($(this).clone(true)).remove();  
}else{
  this.setAttribute('type', 'text');
  this.setAttribute('type', 'file'); 
}

may not be the most elegant solution, but it work as far as I can tell.

The short answer is no (technically you can give whatever name of the class you want, but this will have no effect, unless you define your own CSS class - and remember - no dots in the class selector). The long answer is again no, because Bootstrap includes a responsive, mobile first fluid grid system that appropriately scales up to 12 columns as the device or view port size increases.

Rows must be placed within a .container (fixed-width) or .container-fluid (full-width) for proper alignment and padding.

• Use rows to create horizontal groups of columns.
• Content should be placed within columns, and only columns may be immediate children of rows.
• Predefined grid classes like .row and .col-xs-4 are available for quickly making grid layouts. Less mixins can also be used for more semantic layouts.
• Columns create gutters (gaps between column content) via padding. That padding is offset in rows for the first and last column via negative margin on .rows.
• Grid columns are created by specifying the number of twelve available columns you wish to span. For example, three equal columns would use three .col-xs-4.
• If more than 12 columns are placed within a single row, each group of extra columns will, as one unit, wrap onto a new line.
• Grid classes apply to devices with screen widths greater than or equal to the breakpoint sizes, and override grid classes targeted at smaller devices. Therefore, e.g. applying any .col-md-* class to an element will not only affect its styling on medium devices but also on large devices if a .col-lg-* class is not present.

A possible solution to your problem is to define your own CSS class with desired width, let's say .col-half{width:XXXem !important} then add this class to elements you want along with original Bootstrap CSS classes.

I want to extend @Jan answer:

It's seems, that Task Scheduler 1.0 API uses C:\Windows\Tasks folder for create and enumerate tasks (this example), while Task Scheduler 2.0 API uses C:\Windows\System32\Tasks to create and enumerate tasks (this example).

It's also seems, that windows console utility schtasks and GUI utility taskschd.msc uses Task Scheduler 2.0 API.

P.S. I found, that if task placed in C:\Windows\Tasks and have not set AccountInformation, then task won't be displayed in windows console and GUI schedulers. If you set AccountInformation (even "" for SYSTEM account) and set flag TASK_FLAG_RUN_ONLY_IF_LOGGED_ON - task will be displayed in all standard applications.

   });           
}

Here is what needs to go in D1: =VLOOKUP(C1, $A$1:$B$4, 2, FALSE)

You should then be able to copy this down to the rest of column D.

It is possible in css, but not for all the browsers.

The effect on all browsers:

I found the error when using a combination of the Ajax Control Toolkit ToolkitScriptManager and URL Write 2.0.

In my <rewrite> <outboundRules> I had a precondition:

<preConditions>
    <preCondition name="IsHTML">
        <add input="{RESPONSE_CONTENT_TYPE}" pattern="^text/html"/>

</preConditions>

But apparently some of my outbound rules weren't set to use the precondition.

Once I had that preCondition set on all my outbound rules:

<rule preCondition="IsHTML" name="MyOutboundRule">

No more problem.

I already found it:

Prior to PHP 7 type hinting can only be used to force the types of objects and arrays. Scalar types are not type-hintable. In this case an object of the class string is expected, but you're giving it a (scalar) string. The error message may be funny, but it's not supposed to work to begin with. Given the dynamic typing system, this actually makes some sort of perverted sense.

You can only manually "type hint" scalar types:

function foo($string) {
    if (!is_string($string)) {
        trigger_error('No, you fool!');
        return;
    }
    ...
}

I just input some value that I knew was invalid and here is the output:

'whatToInput' is not a supported event for HtmlPanelGrid. Please specify one of these supported event names: click, dblclick, keydown, keypress, keyup, mousedown, mousemove, mouseout, mouseover, mouseup.

So values you can pass to event are

• click
• dblclick
• keydown
• mousedown
• mousemove
• mouseover
• mouseup

You say "this is a piece of java code being written", from which I infer that there is still a chance that you could design it a different way.

Having an ArrayList is like having a collection of stuff. Rather than force the instanceof or getClass every time you take an object from the list, why not design the system so that you get the type of the object when you retrieve it from the DB, and store it into a collection of the appropriate type of object?

Or, you could use one of the many data access libraries that exist to do this for you.

Maybe not very elegant, but it does the job:

exec(open("script.py").read())

d and i conversion specifiers behave the same with fprintf but behave differently for fscanf.

As some other wrote in their answer, the idiomatic way to print an int is using d conversion specifier.

Regarding i specifier and fprintf, C99 Rationale says that:

The %i conversion specifier was added in C89 for programmer convenience to provide symmetry with fscanf’s %i conversion specifier, even though it has exactly the same meaning as the %d conversion specifier when used with fprintf.

An interface is used for polymorphism, which applies to Objects, not types. Therefore (as already noted) it makes no sense to have an static interface member.

file1.php

<?php

    function func1($param1, $param2)
    {
        echo $param1 . ', ' . $param2;
    }

file2.php

<?php

    require_once('file1.php');

    func1('Hello', 'world');

See manual

Generally

static: no need to create object we can directly call using

ClassName.methodname()

Non Static: we need to create a object like

ClassName obj=new ClassName()
obj.methodname();

You could use XMLTABLE:

SELECT rownum
FROM XMLTABLE('1 to 100');

-- alternatively(useful for generating range i.e. 10-20)
SELECT (COLUMN_VALUE).GETNUMBERVAL() AS NUM
FROM XMLTABLE('1 to 100');

I agree with georgebrock's comment.

If you find a way to get //TRANSLIT to work, you can build friendly URLs:

1. use iconv with //TRANSLIT ñ => n~
   • remove non-alphanumeric non-whitespace chars inside words: $url = preg_replace( '/(\w)[^\w\s](\w)/', '$1$2', $url );
   • replace remaining separations: $url = preg_replace( '/[^a-z0-9]+/', '-', $url );
   • remove double/leading/traling: $url = preg_replace( '-', e.g. '/(?:(^|\-)\-+|\-$)/', '', $url );

If you can't get it to work, replace setp 1 with strtr/character-based replacement, like Xetius' solution.

Understanding the available syntaxes of arrow functions will give you an understanding of what behaviour they are introducing when 'chained' like in the examples you provided.

When an arrow function is written without block braces, with or without multiple parameters, the expression that constitutes the function's body is implicitly returned. In your example, that expression is another arrow function.

No arrow funcs              Implicitly return `e=>{…}`    Explicitly return `e=>{…}` 
---------------------------------------------------------------------------------
function (field) {         |  field => e => {            |  field => {
  return function (e) {    |                             |    return e => {
      e.preventDefault()   |    e.preventDefault()       |      e.preventDefault()
  }                        |                             |    }
}                          |  }                          |  }

Another advantage of writing anonymous functions using the arrow syntax is that they are bound lexically to the scope in which they are defined. From 'Arrow functions' on MDN:

An arrow function expression has a shorter syntax compared to function expressions and lexically binds the this value. Arrow functions are always anonymous.

This is particularly pertinent in your example considering that it is taken from a reactjs application. As as pointed out by @naomik, in React you often access a component's member functions using this. For example:

Unbound                     Explicitly bound            Implicitly bound 
------------------------------------------------------------------------------
function (field) {         |  function (field) {       |  field => e => {
  return function (e) {    |    return function (e) {  |    
      this.setState(...)   |      this.setState(...)   |    this.setState(...)
  }                        |    }.bind(this)           |    
}                          |  }.bind(this)             |  }

I had issues with some of the above solutions, with getting the correct "bounding_box" or new size of the image. Therefore here is my version

def rotation(image, angleInDegrees):
    h, w = image.shape[:2]
    img_c = (w / 2, h / 2)

    rot = cv2.getRotationMatrix2D(img_c, angleInDegrees, 1)

    rad = math.radians(angleInDegrees)
    sin = math.sin(rad)
    cos = math.cos(rad)
    b_w = int((h * abs(sin)) + (w * abs(cos)))
    b_h = int((h * abs(cos)) + (w * abs(sin)))

    rot[0, 2] += ((b_w / 2) - img_c[0])
    rot[1, 2] += ((b_h / 2) - img_c[1])

    outImg = cv2.warpAffine(image, rot, (b_w, b_h), flags=cv2.INTER_LINEAR)
    return outImg

Because your question is phrased regarding your error message and not whatever your function is trying to accomplish, I will address the error.

- is the 'binary operator' your error is referencing, and either CurrentDay or MA (or both) are non-numeric.

A binary operation is a calculation that takes two values (operands) and produces another value (see wikipedia for more). + is one such operator: "1 + 1" takes two operands (1 and 1) and produces another value (2). Note that the produced value isn't necessarily different from the operands (e.g., 1 + 0 = 1).

R only knows how to apply + (and other binary operators, such as -) to numeric arguments:

> 1 + 1
[1] 2
> 1 + 'one'
Error in 1 + "one" : non-numeric argument to binary operator

When you see that error message, it means that you are (or the function you're calling is) trying to perform a binary operation with something that isn't a number.

EDIT:

Your error lies in the use of [ instead of [[. Because Day is a list, subsetting with [ will return a list, not a numeric vector. [[, however, returns an object of the class of the item contained in the list:

> Day <- Transaction(1, 2)["b"]
> class(Day)
[1] "list"

Error in Day + 1 : non-numeric argument to binary operator

Transaction, as you've defined it, returns a list of two vectors. Above, Day is a list contain one vector. Day2, however, is simply a vector.

I got this error when I tried adding a column from a different table. Indeed I got duplicate index values along the way. But it turned out I was just doing it wrong: I actually needed to df.join the other table.

This pointer might help someone in a similar situation.

Your code doesn't work for binary files because they can't be cast to strings in the data event handler. If you need to manipulate binary files you'll need to use a buffer. Sorry, I do not have an example of using a buffer because in my case I needed to manipulate HTML files. I just check the content type and then for text/html files update them as needed:

app.get('/*', function(clientRequest, clientResponse) {
  var options = { 
    hostname: 'google.com',
    port: 80, 
    path: clientRequest.url,
    method: 'GET'
  };  

  var googleRequest = http.request(options, function(googleResponse) { 
    var body = ''; 

    if (String(googleResponse.headers['content-type']).indexOf('text/html') !== -1) {
      googleResponse.on('data', function(chunk) {
        body += chunk;
      }); 

      googleResponse.on('end', function() {
        // Make changes to HTML files when they're done being read.
        body = body.replace(/google.com/gi, host + ':' + port);
        body = body.replace(
          /<\/body>/, 
          '<script src="http://localhost:3000/new-script.js" type="text/javascript"></script></body>'
        );

        clientResponse.writeHead(googleResponse.statusCode, googleResponse.headers);
        clientResponse.end(body);
      }); 
    }   
    else {
      googleResponse.pipe(clientResponse, {
        end: true
      }); 
    }   
  }); 

  googleRequest.end();
});    

Lazy loading - is good when handling with pagination like on page load list of users appear which contains 10 users and as the user scrolls down the page an api call brings next 10 users.Its good when you don't want to load enitire data at once as it would take more time and would give bad user experience.

Eager loading - is good as other people suggested when there are not much relations and fetch entire data at once in single call to database

If you're having trouble with paths you can use

require Rails.root + 'db/migrate/20090408054532_add_foos.rb'

You need to enclose that in <%! %> as follows:

<%!

public String getQuarter(int i){
String quarter;
switch(i){
        case 1: quarter = "Winter";
        break;

        case 2: quarter = "Spring";
        break;

        case 3: quarter = "Summer I";
        break;

        case 4: quarter = "Summer II";
        break;

        case 5: quarter = "Fall";
        break;

        default: quarter = "ERROR";
}

return quarter;
}

%>

You can then invoke the function within scriptlets or expressions:

<%
     out.print(getQuarter(4));
%>

or

<%= getQuarter(17) %>

For numerical data you have the solution. But it is categorical data, you said. Then life gets a bit more complicated...

Well, first : The amount of association between two categorical variables is not measured with a Spearman rank correlation, but with a Chi-square test for example. Which is logic actually. Ranking means there is some order in your data. Now tell me which is larger, yellow or red? I know, sometimes R does perform a spearman rank correlation on categorical data. If I code yellow 1 and red 2, R would consider red larger than yellow.

So, forget about Spearman for categorical data. I'll demonstrate the chisq-test and how to choose columns using combn(). But you would benefit from a bit more time with Agresti's book : http://www.amazon.com/Categorical-Analysis-Wiley-Probability-Statistics/dp/0471360937

set.seed(1234)
X <- rep(c("A","B"),20)
Y <- sample(c("C","D"),40,replace=T)

table(X,Y)
chisq.test(table(X,Y),correct=F)
# I don't use Yates continuity correction

#Let's make a matrix with tons of columns

Data <- as.data.frame(
          matrix(
            sample(letters[1:3],2000,replace=T),
            ncol=25
          )
        )

# You want to select which columns to use
columns <- c(3,7,11,24)
vars <- names(Data)[columns]

# say you need to know which ones are associated with each other.
out <-  apply( combn(columns,2),2,function(x){
          chisq.test(table(Data[,x[1]],Data[,x[2]]),correct=F)$p.value
        })

out <- cbind(as.data.frame(t(combn(vars,2))),out)

Then you should get :

> out
   V1  V2       out
1  V3  V7 0.8116733
2  V3 V11 0.1096903
3  V3 V24 0.1653670
4  V7 V11 0.3629871
5  V7 V24 0.4947797
6 V11 V24 0.7259321

Where V1 and V2 indicate between which variables it goes, and "out" gives the p-value for association. Here all variables are independent. Which you would expect, as I created the data at random.

You certainly want to hack the header to have a proper Ajax Request :

headers = {'X_REQUESTED_WITH' :'XMLHttpRequest',
           'ACCEPT': 'application/json, text/javascript, */*; q=0.01',}
request = urllib2.Request(path, data, headers)
response = urllib2.urlopen(request).read()

And to json.loads the POST on the server-side.

Edit : By the way, you have to urllib.urlencode(mydata_dict) before sending them. If you don't, the POST won't be what the server expect

Use the PasteSpecial method:

sht.Columns("A:G").Copy
Range("A1").PasteSpecial Paste:=xlPasteValues

BUT your big problem is that you're changing your ActiveSheet to "Data" and not changing it back. You don't need to do the Activate and Select, as per my code (this assumes your button is on the sheet you want to copy to).

For what it's worth: I just had the same problem, after editing the nginx.conf file. I tried and tried restarting it by commanding sudo nginx restart and various other commands. None of them produced any output. Commanding sudo nginx -t to check the configuration file gave the output sudo: nginx: command not found, which was puzzling. I was starting to think there were problems with the path.

Finally, I logged in as root (sudo su) and commanded sudo nginx restart. Now, the command displayed an error message concerning the configuration file. After fixing that, it restarted successfully.

Interestingly, if you're just typing at the python interactive interpreter, you have to follow a function with a blank line. This does not work:

def foo(x):
  return x+1
print "last"

although it is perfectly legal python syntax in a file. There are other syntactic differences when typing to the interpreter too, so beware.

public ActionResult OrderDel(int id)
    {
        string a = Session["UserSession"].ToString();
        var s = (from test in ob.Order_Details where test.Email_ID_Fk == a && test.Order_ID == id select test).FirstOrDefault();
        s.Status = "Order Cancel By User";
        ob.SaveChanges();
        //foreach(var updter in s)
        //{
        //    updter.Status = "Order Cancel By User";
        //}


        return Json("Sucess", JsonRequestBehavior.AllowGet);
    } <script>
            function Cancel(id) {
                if (confirm("Are your sure ? Want to Cancel?")) {
                    $.ajax({

                        type: 'POST',
                        url: '@Url.Action("OrderDel", "Home")/' + id,
                        datatype: 'JSON',
                        success: function (Result) {
                            if (Result == "Sucess")
                            {
                                alert("Your Order has been Canceled..");
                                window.location.reload();
                            }
                        },
                        error: function (Msgerror) {
                            alert(Msgerror.responseText);
                        }


                    })
                }
            }

        </script>

Just build your String in HTML and set it:

String sourceString = "<b>" + id + "</b> " + name; 
mytextview.setText(Html.fromHtml(sourceString));

In JavaScript everything is an object

console.log(type of({}))  //Object
console.log(type of([]))  //Object

To get Real type , use this

console.log(Object.prototype.toString.call({}))   //[object Object]
console.log(Object.prototype.toString.call([]))   //[object Array]

Hope this helps

I assume you are executing all of the above code each time you write something to the file. Each time the stream for the file is opened, its seek pointer is positioned at the beginning so all writes end up overwriting what was there before.

You can solve the problem in two ways: either with the convenient

file2 = new StreamWriter("c:/file.txt", true);

or by explicitly repositioning the stream pointer yourself:

file2 = new StreamWriter("c:/file.txt");
file2.BaseStream.Seek(0, SeekOrigin.End);

Here is the java version for somemone who whould like to do it on server side using the String returned by HttpServletRequest.getHeader("User-Agent");

It is working on the 70 different browser configuration I used for testing.

public static String decodeBrowser(String userAgent) {
    userAgent= userAgent.toLowerCase();
    String name = "unknown";
    String version = "0.0";
    Matcher userAgentMatcher = USER_AGENT_MATCHING_PATTERN.matcher(userAgent);
    if (userAgentMatcher.find()) {
      name = userAgentMatcher.group(1);
      version = userAgentMatcher.group(2);
      if ("trident".equals(name)) {
        name = "msie";
        Matcher tridentVersionMatcher = TRIDENT_MATCHING_PATTERN.matcher(userAgent);
        if (tridentVersionMatcher.find()) {
          version = tridentVersionMatcher.group(1);
        }
      }
    }
    return name + " " + version;
  }

  private static final Pattern USER_AGENT_MATCHING_PATTERN=Pattern.compile("(opera|chrome|safari|firefox|msie|trident(?=\\/))\\/?\\s*([\\d\\.]+)");
  private static final Pattern TRIDENT_MATCHING_PATTERN=Pattern.compile("\\brv[ :]+(\\d+(\\.\\d+)?)");

If you want you can achieve this using a CLR Function/Assembly.

1. Create a SQL Server CLR Assembly Project.
2. Go to properties and ensure the permission level on the Connection is setup to external
3. Add A Sql Function to the Assembly.

Here's an example which will allow you to select form your result set like a table.

public partial class UserDefinedFunctions
{
    [SqlFunction(DataAccess = DataAccessKind.Read,
        FillRowMethodName = "GetFiles_FillRow", TableDefinition = "FilePath nvarchar(4000)")]
    public static IEnumerable GetFiles(SqlString path)
    {
        return System.IO.Directory.GetFiles(path.ToString()).Select(s => new SqlString(s));
    }

    public static void GetFiles_FillRow(object obj,out SqlString filePath)
    {
        filePath = (SqlString)obj;
    }
};

And your SQL query.

use MyDb

select * From GetFiles('C:\Temp\');

Be aware though, your database needs to have CLR Assembly functionaliy enabled using the following SQL Command.

sp_configure 'clr enabled', 1
GO
RECONFIGURE
GO

CLR Assemblies (like XP_CMDShell) are disabled by default so if the reason for not using XP Cmd Shell is because you don't have permission, then you may be stuck with this option as well... just FYI.

In principle, I agree with Ignacio, above, but you can also use type to check if something is a tuple or a list.

>>> a = (1,)
>>> type(a)
(type 'tuple')
>>> a = [1]
>>> type(a)
(type 'list')

static variables are specific to a class . Constructors initialize attributes ESPECIALY for an instance.

Since this question is the first in search results, I'll put a different solution for a different problem here anyway, in order not to have a duplicate title.

The same error message can come up when running a query file in psql without specifying a database. Since there is no use statement in postgresql, we have to specify the database on the command line, for example:

psql -d db_name -f query_file.sql

If the error is at the time of any calculation, double check that the values does not contains any comma(,). Values must be only in integer/ float format.

If you need permissions, you cannot use 'pip' with 'sudo'. You can do a trick, so that you can use 'sudo' and install package. Just place 'sudo python -m ...' in front of your pip command.

sudo python -m pip install --user -r package_name

Also, you can use this...

DECLARE @SeqID varchar(150);
DECLARE @TableName varchar(150);
SET @TableName = (Select TableName from Table);
SET @SeqID = 'SELECT NEXT VALUE FOR ' + @TableName + '_Data'
exec (@SeqID)

There are standard statistical functions and methods for finding outliers to data, which is probably what you need in the first case. Using derivatives would solve your second. I'm not sure for a method which solves both continuous functions and sampled data, however.

Try this:

<script>
document.addEventListener("touchstart", function(){}, true);
</script>

And in your CSS:

element:hover, element:active {
-webkit-tap-highlight-color: rgba(0,0,0,0);
-webkit-user-select: none;
-webkit-touch-callout: none /*only to disable context menu on long press*/
}

With this code you don't need an extra .hover class!

1. Insert a column at the left of the table 'Control'
2. Number the data as 1 to 1000 (assuming there are 1000 rows)
3. Copy the key field to another sheet and remove duplicates
4. Copy the unique row items to the main sheet, after 1000th record
5. In the 'Control' column, add number 1001 to all unique records
6. Sort the data (including the added records), first on key field and then on 'Control'
7. A blank line (with data in key field and 'Control') is added

template<unsigned long N>
struct bin {
    enum { value = (N%10)+2*bin<N/10>::value };
} ;

template<>
struct bin<0> {
    enum { value = 0 };
} ;

// ...
    std::cout << bin<1000>::value << '\n';

The leftmost digit of the literal still has to be 1, but nonetheless.

Using the standard CustomCreationConverter, I was struggling to work how to generate the correct type (Person or Employee), because in order to determine this you need to analyse the JSON and there is no built in way to do this using the Create method.

I found a discussion thread pertaining to type conversion and it turned out to provide the answer. Here is a link: Type converting.

What's required is to subclass JsonConverter, overriding the ReadJson method and creating a new abstract Create method which accepts a JObject.

The JObject class provides a means to load a JSON object and provides access to the data within this object.

The overridden ReadJson method creates a JObject and invokes the Create method (implemented by our derived converter class), passing in the JObject instance.

This JObject instance can then be analysed to determine the correct type by checking existence of certain fields.

Example

string json = "[{
        \"Department\": \"Department1\",
        \"JobTitle\": \"JobTitle1\",
        \"FirstName\": \"FirstName1\",
        \"LastName\": \"LastName1\"
    },{
        \"Department\": \"Department2\",
        \"JobTitle\": \"JobTitle2\",
        \"FirstName\": \"FirstName2\",
        \"LastName\": \"LastName2\"
    },
        {\"Skill\": \"Painter\",
        \"FirstName\": \"FirstName3\",
        \"LastName\": \"LastName3\"
    }]";

List<Person> persons = 
    JsonConvert.DeserializeObject<List<Person>>(json, new PersonConverter());

...

public class PersonConverter : JsonCreationConverter<Person>
{
    protected override Person Create(Type objectType, JObject jObject)
    {
        if (FieldExists("Skill", jObject))
        {
            return new Artist();
        }
        else if (FieldExists("Department", jObject))
        {
            return new Employee();
        }
        else
        {
            return new Person();
        }
    }

    private bool FieldExists(string fieldName, JObject jObject)
    {
        return jObject[fieldName] != null;
    }
}

public abstract class JsonCreationConverter<T> : JsonConverter
{
    /// <summary>
    /// Create an instance of objectType, based properties in the JSON object
    /// </summary>
    /// <param name="objectType">type of object expected</param>
    /// <param name="jObject">
    /// contents of JSON object that will be deserialized
    /// </param>
    /// <returns></returns>
    protected abstract T Create(Type objectType, JObject jObject);

    public override bool CanConvert(Type objectType)
    {
        return typeof(T).IsAssignableFrom(objectType);
    }

    public override bool CanWrite
    {
        get { return false; }
    }

    public override object ReadJson(JsonReader reader, 
                                    Type objectType, 
                                     object existingValue, 
                                     JsonSerializer serializer)
    {
        // Load JObject from stream
        JObject jObject = JObject.Load(reader);

        // Create target object based on JObject
        T target = Create(objectType, jObject);

        // Populate the object properties
        serializer.Populate(jObject.CreateReader(), target);

        return target;
    }
}

First, checkout to your Branch3:

git checkout Branch3

Then merge the Branch1:

git merge Branch1

And if you want the updated commits of Branch1 on Branch2, you are probaly looking for git rebase

git checkout Branch2
git rebase Branch1

This will update your Branch2 with the latest updates of Branch1.

I don't have reputation to comment yet, but I want to add to alko answer for further reference.

From the docs:

skiprows: A collection of numbers for rows in the file to skip. Can also be an integer to skip the first n rows

As a clarification to the suggestion by Ryan Fox to split the screen into regions, and only checking for collisions within regions...

e.g. split the play area up into a grid of squares (which will will arbitrarily say are of 1 unit length per side), and check for collisions within each grid square.

That's absolutely the correct solution. The only problem with it (as another poster pointed out) is that collisions across boundaries are a problem.

The solution to this is to overlay a second grid at a 0.5 unit vertical and horizontal offset to the first one.

Then, any collisions that would be across boundaries in the first grid (and hence not detected) will be within grid squares in the second grid. As long as you keep track of the collisions you've already handled (as there is likely to be some overlap) you don't have to worry about handling edge cases. All collisions will be within a grid square on one of the grids.

In Safari 9.0 and up you can use shrink-to-fit in viewport meta tag as shown below

<meta name="viewport" content="width=device-width, initial-scale=1.0, shrink-to-fit=no">

Change to your variable types private to public

This is simple and more readable.

For example

Not Working;

class A{
   private $var1="valuevar1";
   private $var2="valuevar2";
   public function tojson(){
    return json_encode($this)
   }
}

It is Working;

class A{
   public $var1="valuevar1";
   public $var2="valuevar2";
   public function tojson(){
    return json_encode($this)
   }
}

I had the same error. The problem for me was, that after saving the entity the mapped collection was still null and when trying to update the entity the exception was thrown. What helped for me: Saving the entity, then make a refresh (collection is no longer null) and then perform the update. Maybe initializing the collection with new ArrayList() or something might help as well.

Especially for non-UTC timezones:

The only timezone that has its own method is timezone.utc, but you can fudge a timezone with any UTC offset if you need to by using timedelta & timezone, and forcing it using .replace.

In [1]: from datetime import datetime, timezone, timedelta

In [2]: def force_timezone(dt, utc_offset=0):
   ...:     return dt.replace(tzinfo=timezone(timedelta(hours=utc_offset)))
   ...:

In [3]: dt = datetime(2011,8,15,8,15,12,0)

In [4]: str(dt)
Out[4]: '2011-08-15 08:15:12'

In [5]: str(force_timezone(dt, -8))
Out[5]: '2011-08-15 08:15:12-08:00'

Using timezone(timedelta(hours=n)) as the time zone is the real silver bullet here, and it has lots of other useful applications.

A much, much more elegant solution is to use a UIView subclass (though this isn't always appropriate) and recalculate all your subviews on a parent's frame change (and be smart: only recalculate them if the new frame size has changed, i.e. use CGRectEqualToRect to compare the new frame when you override setFrame and BEFORE you call [super setFrame:frame_]). The only catch to this is that the UIViewController you intend to use should probably listen to keyboard events (or, you could do it in the UIView itself, for handy encapsulation). But only the UIKeyboardWillShowNotification and UIKeyboardWillHideNotification. This is just so it will look smooth (if you wait for CG to call it, you will get a moment of choppiness).

This has the advantage of building a UIView subclass that does the right thing, anyway.

The naive implementation would be to override drawRect: (don't), a better one would be to just use layoutSubviews (and then in the UIViewController, or whatnot you can call [view setNeedsLayout] in a SINGLE method that is called for either show or hide).

This solution gets away from hardcoding a keyboard offset (which will change if they are not in split, etc) and also means that your view could be a subview of many other views and still respond properly.

Don't hardcode something like that unless there is no other solution. The OS gives you enough info, if you've done things right, that you just need to redraw intelligently (based on your new frame size). This is much cleaner and the way you should do things. (There may be an even better approach, though.)

My solution for BlueJ is to edit the New Class template "stdclass.tmpl" in Program Files (x86)\BlueJ\lib\english\templates\newclass and add this method:

public static <T> void p(T s)
{
    System.out.println(s);
}

Or this other version:

public static void p(Object s)
{
    System.out.println(s);
}

As for Eclipse I'm using the suggested shortcut syso + <Ctrl> + <Space> :)

I would suggest using numpy's sort, as it is anyway what pandas is doing in background:

import numpy as np
np.sort(df.A.unique())

But doing all in pandas is valid as well.

This is not possible with native HTML input elements. You can use webshim polyfill, which gives you this option by using this markup.

<input type="date" data-date-inline-picker="true" />

Here is a small demo

That's a very complex question for a simple answer.

You may want to take a look at existing API frameworks, like Swagger Specification (OpenAPI), and services like apiary.io and apiblueprint.org.

Also, here's an example of the same REST API described, organized and even styled in three different ways. It may be a good start for you to learn from existing common ways.

• https://api.coinsecure.in/v1
• https://api.coinsecure.in/v1/originalUI
• https://api.coinsecure.in/v1/slateUI#!/Blockchain_Tools/v1_bitcoin_search_txid

At the very top level I think quality REST API docs require at least the following:

• a list of all your API endpoints (base/relative URLs)
• corresponding HTTP GET/POST/... method type for each endpoint
• request/response MIME-type (how to encode params and parse replies)
• a sample request/response, including HTTP headers
• type and format specified for all params, including those in the URL, body and headers
• a brief text description and important notes
• a short code snippet showing the use of the endpoint in popular web programming languages

Also there are a lot of JSON/XML-based doc frameworks which can parse your API definition or schema and generate a convenient set of docs for you. But the choice for a doc generation system depends on your project, language, development environment and many other things.

Add a reference to Microsoft.VisualBasic and a using Microsoft.VisualBasic.Devices;.

The ComputerInfo class has all the information that you need.

Function ListRowCount(ByVal FirstCellName as String) as Long
    With thisworkbook.Names(FirstCellName).RefersToRange
        If isempty(.Offset(1,0).value) Then 
            ListRowCount = 1
        Else
            ListRowCount = .End(xlDown).row - .row + 1
        End If
    End With
End Function

But if you are damn sure there's nothing around the list, then just thisworkbook.Names(FirstCellName).RefersToRange.CurrentRegion.rows.count

You can also use an oracle defined collection

DECLARE 
  arrayvalues sys.odcivarchar2list;
BEGIN
  arrayvalues := sys.odcivarchar2list('Matt','Joanne','Robert');
  FOR x IN ( SELECT m.column_value m_value
               FROM table(arrayvalues) m )
  LOOP
    dbms_output.put_line (x.m_value||' is a good pal');
  END LOOP;
END;

I would use in-memory array. But with the .COUNT improvement suggested by uziberia:

DECLARE
  TYPE t_people IS TABLE OF varchar2(10) INDEX BY PLS_INTEGER;
  arrayvalues t_people;
BEGIN
  SELECT *
   BULK COLLECT INTO arrayvalues
   FROM (select 'Matt' m_value from dual union all
         select 'Joanne'       from dual union all
         select 'Robert'       from dual
    )
  ;
  --
  FOR i IN 1 .. arrayvalues.COUNT
  LOOP
    dbms_output.put_line(arrayvalues(i)||' is my friend');
  END LOOP;
END;

Another solution would be to use a Hashmap like @Jchomel did here.

NB:

With Oracle 12c you can even query arrays directly now!

Merge a branch into new one (squash) and remove the files not needed:

git checkout master
git checkout -b <branch>
git merge --squash <source-branch-with-many-commits>
git reset HEAD <not-needed-file-1>
git checkout -- <not-needed-file-1>
git reset HEAD <not-needed-file-2>
git checkout -- <not-needed-file-2>
git commit

To use that in-class initialization syntax, the constant must be a static const of integral or enumeration type initialized by a constant expression.

This is the restriction. Hence, in this case you need to define variable outside the class. refer answwer from @AndreyT

use & in place of &

change to

<string name="magazine">Newspaper &amp; Magazines</string>

You can stringify the JSON Object with JSON.stringify(jsonObject) and receive it on controller as String.

In the Controller, you can use the javax.json to convert and manipulate this.

Download and add the .jar to the project libs and import the JsonObject.

To create an json object, you can use

JsonObjectBuilder job = Json.createObjectBuilder();
job.add("header1", foo1);
job.add("header2", foo2);
JsonObject json = job.build();

To read it from String, you can use

JsonReader jr = Json.createReader(new StringReader(jsonString));
JsonObject json = jsonReader.readObject();
jsonReader.close();

You can specify minimum and maximum pool size by specifying MinPoolSize=xyz and/or MaxPoolSize=xyz in the connection string. This cause of the problem could be a different thing however.

Slow, ugly, platform-specific... but one-liner ;-)

import subprocess

contents = subprocess.Popen('cat %s' % filename, shell = True, stdout = subprocess.PIPE).communicate()[0]

Swift 3.0 (macOS 10.10 and later), you can get it from className

I was facing exact same error

Computed property "callRingtatus" was assigned to but it has no setter

here is a sample code according to my scenario

computed: {

callRingtatus(){
            return this.$store.getters['chat/callState']===2
      }

}

I change the above code into the following way

computed: {

callRingtatus(){
       return this.$store.state.chat.callState===2
    }
}

fetch values from vuex store state instead of getters inside the computed hook

For the more unusual charts: http://thejit.org/

This is how I've done it using parameterized commands.

MSSQL

 INSERT INTO MyTable (Field1, Field2) VALUES (@Value1, @Value2); 
 SELECT SCOPE_IDENTITY(); 

MySQL

 INSERT INTO MyTable (Field1, Field2) VALUES (?Value1, ?Value2);
 SELECT LAST_INSERT_ID();

You can also use REPLACE():

UPDATE Table
   SET Column = REPLACE(Column, 'Test123', 'Test')

i have tried this one and it worked for me. hope it works for others too.

1. Open build.gradle module file
2. downgrade you sdkversion from 25 to 24 or 23
3. add 'multiDexEnabled true'
4. comment this line : compile 'com.android.support:appcompat-v7:25.1.0' (if it's in 'dependencies')
5. Sync your project and ready to go.

Here i have attached screenshot to explain things. Go through this steps

happy to help.

thanks.

You can use the bootstrap template from

http://www.initializr.com/

which includes all the bootstrap .less files. You can then change variables / update the less files as you want and it will automatically compile the css. When deploying compile the less file to css.

The characters '<', and '>', are to indicate a place-holder, you should remove them to read:

php /usr/local/solusvm/scripts/pass.php --type=admin --comm=change --username=ADMINUSERNAME

If you need to parse ASN.1 objects in script, there's a library for that: https://github.com/lapo-luchini/asn1js

For doing the math, I found jsbn convenient: http://www-cs-students.stanford.edu/~tjw/jsbn/

Walking the ASN.1 structure and extracting the exp/mod/subject/etc. is up to you -- I never got that far!

distinct is not a function. It always operates on all columns of the select list.

Your problem is a typical "greatest N per group" problem which can easily be solved using a window function:

select ...
from (
  select IDNo,
         FirstName,
         LastName,
         ....,
         row_number() over (partition by lower(idno) order by firstname) as rn 
  from people 
) t
where rn = 1;

Using the order by clause you can select which of the duplicates you want to pick.

The above can be used in a left join, see below:

select ...
from x
  left join (
    select IDNo,
           FirstName,
           LastName,
           ....,
           row_number() over (partition by lower(idno) order by firstname) as rn 
    from people 
  ) p on p.idno = x.idno and p.rn = 1
where ...

Don't include header.php. You should not output HTML when you are going to redirect.

Make a new file, eg. "pre.php". Put this in it:

<?php
include('class.user.php');
include('class.Connection.php');
?>

Then in header.php, include that, in stead of including the two other files. In form.php, include pre.php in stead of header.php.

You could use penlight library. This has a function size which gives the actual size of the table.

It has implemented many of the function that we may need while programming and missing in Lua.

Here is the sample for using it.

> tablex = require "pl.tablex"
> a = {}
> a[2] = 2
> a[3] = 3 
> a['blah'] = 24

> #a
0

> tablex.size(a)
3

I would recommend adding a boolean check for the magnitude of the number. I'm converting a high milliseconds value to datetime. I have numbers from 2 to 200,000,200 so 0 is a valid output. The function as @Chris Mueller has it will return 0 even if number is smaller than 10**n.

def get_digit(number, n):
    return number // 10**n % 10

get_digit(4231, 5)
# 0

def get_digit(number, n):
    if number - 10**n < 0:
        return False
    return number // 10**n % 10

get_digit(4321, 5)
# False

You do have to be careful when checking the boolean state of this return value. To allow 0 as a valid return value, you cannot just use if get_digit:. You have to use if get_digit is False: to keep 0 from behaving as a false value.

Your markup:

<input type="text" class="resizedTextbox" />

The CSS:

.resizedTextbox {width: 100px; height: 20px}

Keep in mind that text box size is a "victim" of the W3C box model. What I mean by victim is that the height and width of a text box is the sum of the height/width properties assigned above, in addition to the padding height/width, and the border width. For this reason, your text boxes will be slightly different sizes in different browsers depending on the default padding in different browsers. Although different browsers tend to define different padding to text boxes, most reset style sheets don't tend to include <input /> tags in their reset sheets, so this is something to keep in mind.

You can standardize this by defining your own padding. Here is your CSS with specified padding, so the text box looks the same in all browsers:

.resizedTextbox {width: 100px; height: 20px; padding: 1px}

I added 1 pixel padding because some browsers tend to make the text box look too crammed if the padding is 0px. Depending on your design, you may want to add even more padding, but it is highly recommend you define the padding yourself, otherwise you'll be leaving it up to different browsers to decide for themselves. For even more consistency across browsers, you should also define the border yourself.

Yes, like in plain sql you could specify what kind of properties you want to select:

SELECT i.firstProperty, i.secondProperty FROM ObjectName i WHERE i.id=10

Executing this query will return a list of Object[], where each array contains the selected properties of one object.

Another way is to wrap the selected properties in a custom object and execute it in a TypedQuery:

String query = "SELECT NEW CustomObject(i.firstProperty, i.secondProperty) FROM ObjectName i WHERE i.id=10";
TypedQuery<CustomObject> typedQuery = em.createQuery(query , CustomObject.class);
List<CustomObject> results = typedQuery.getResultList();

Examples can be found in this article.

UPDATE 29.03.2018:

@Krish:

@PatrickLeitermann for me its giving "Caused by: org.hibernate.hql.internal.ast.QuerySyntaxException: Unable to locate class ***" exception . how to solve this ?

I guess you’re using JPA in the context of a Spring application, don't you? Some other people had exactly the same problem and their solution was adding the fully qualified name (e. g. com.example.CustomObject) after the SELECT NEW keywords.

Maybe the internal implementation of the Spring data framework only recognizes classes annotated with @Entity or registered in a specific orm file by their simple name, which causes using this workaround.

One possible reason for this error is that your delimiter character (comma, semi-colon, pipe, whatever) actually appears in the data in one column. This can give very misleading error messages, often with the name of a totally different column.

One way to check this is to redirect the 'bad' rows to a separate file and then inspect them manually. Here's a brief explanation of how to do that:

http://redmondmag.com/articles/2010/04/12/log-error-rows-ssis.aspx

If that is indeed your problem, then the best solution is to fix the files at the source to quote the data values and/or use a different delimeter that isn't in the data.

(I found this answer from a video: http://www.youtube.com/watch?v=xmvRF7koJ5E)

1. Download msvcp71.dll and msvcr71.dll from the web.

2. Save them to your C:\Windows\System32 folder.

3. Save them to your C:\Windows\SysWOW64 folder as well (if you have a 64-bit operating system).

Now try running your code file in Python and it will load the graph in couple of seconds.

This worked for me:

select pg_terminate_backend(pid) from pg_stat_activity where datname='YourDatabase';

for postgresql earlier than 9.2 replace pid with procpid

DROP DATABASE "YourDatabase";

http://blog.gahooa.com/2010/11/03/how-to-force-drop-a-postgresql-database-by-killing-off-connection-processes/

Just to show it in a different format that I prefer to use for some reason: The first way returns your itemList as an System.Linq.IOrderedQueryable

using(var context = new ItemEntities())
{
    var itemList = context.Items.Where(x => !x.Items && x.DeliverySelection)
                                .OrderByDescending(x => x.Delivery.SubmissionDate);
}

That approach is fine, but if you wanted it straight into a List Object:

var itemList = context.Items.Where(x => !x.Items && x.DeliverySelection)
                                .OrderByDescending(x => x.Delivery.SubmissionDate).ToList();

All you have to do is append a .ToList() call to the end of the Query.

Something to note, off the top of my head I can't recall if the !(not) expression is acceptable in the Where() call.

This is a good source for answering this question.

But this question is a kind of a always truth answere "Yes. Both."

It depends on your architecture. If you're going to work on a 16-bit machine or less, it can't be 4 byte (=32 bit). If you're working on a 32-bit or better machine, its length is 32-bit.

To figure out, get you program ready to output something readable and use the "sizeof" function. That returns the size in bytes of your declared datatype. But be carfull using this with arrays.

If you're declaring int t[12]; it will return 12*4 byte. To get the length of this array, just use sizeof(t)/sizeof(t[0]). If you are going to build up a function, that should calculate the size of a send array, remember that if

typedef int array[12];
int function(array t){
    int size_of_t = sizeof(t)/sizeof(t[0]);
    return size_of_t;
}
void main(){
    array t = {1,1,1};  //remember: t= [1,1,1,0,...,0]
    int a = function(t);    //remember: sending t is just a pointer and equal to int* t
   print(a);   // output will be 1, since t will be interpreted as an int itselve. 
}

So this won't even return something different. If you define an array and try to get the length afterwards, use sizeof. If you send an array to a function, remember the send value is just a pointer on the first element. But in case one, you always knows, what size your array has. Case two can be figured out by defining two functions and miss some performance. Define function(array t) and define function2(array t, int size_of_t). Call "function(t)" measure the length by some copy-work and send the result to function2, where you can do whatever you want on variable array-sizes.

I'm posting this late answer primarily because Google likes this question.

I believe the issue and context really should be about the workflow, not the tools. The overall philosophy is always "Use the right tool for the job." But before this comes one that many often forget when they get lost in the tools: "Get the job done."

When I have a problem that isn't completely defined, I almost always start with Bash. I have solved some gnarly problems in large Bash scripts that are both readable and maintainable.

But when does the problem start to exceed what Bash should be asked to do? I have some checks I use to give me warnings:

1. Am I wishing Bash had 2D (or higher) arrays? If yes, it's time to realize that Bash is not a great data processing language.
2. Am I doing more work preparing data for other utilities than I am actually running those utilities? If yes, time again to realize Bash is not a great data processing language.
3. Is my script simply getting too large to manage? If yes, it is important to realize that while Bash can import script libraries, it lacks a package system like other languages. It's really a "roll your own" language compared to most others. Then again, it has a enormous amount of functionality built-in (some say too much...)

The list goes on. Bottom-line, when you are working harder to keep your scripts running that you do adding features, it's time to leave Bash.

Let's assume you've decided to move your work to Python. If your Bash scripts are clean, the initial conversion is quite straightforward. There are even several converters / translators that will do the first pass for you.

The next question is: What do you give up moving to Python?

1. All calls to external utilities must be wrapped in something from the subprocess module (or equivalent). There are multiple ways to do this, and until 3.7 it took some effort to get it right (3.7 improved subprocess.run() to handle all common cases on its own).

2. Surprisingly, Python has no standard platform-independent non-blocking utility (with timeout) for polling the keyboard (stdin). The Bash read command is an awesome tool for simple user interaction. My most common use is to show a spinner until the user presses a key, while also running a polling function (with each spinner step) to make sure things are still running well. This is a harder problem than it would appear at first, so I often simply make a call to Bash: Expensive, but it does precisely what I need.

3. If you are developing on an embedded or memory-constrained system, Python's memory footprint can be many times larger than Bash's (depending on the task at hand). Plus, there is almost always an instance of Bash already in memory, which may not be the case for Python.

4. For scripts that run once and exit quickly, Python's startup time can be much longer than Bash's. But if the script contains significant calculations, Python quickly pulls ahead.

5. Python has the most comprehensive package system on the planet. When Bash gets even slightly complex, Python probably has a package that makes whole chunks of Bash become a single call. However, finding the right package(s) to use is the biggest and most daunting part of becoming a Pythonista. Fortunately, Google and StackExchange are your friends.

To animate the transition between fragments, or to animate the process of showing or hiding a fragment you use the Fragment Manager to create a Fragment Transaction.

Within each Fragment Transaction you can specify in and out animations that will be used for show and hide respectively (or both when replace is used).

The following code shows how you would replace a fragment by sliding out one fragment and sliding the other one in it's place.

FragmentTransaction ft = getFragmentManager().beginTransaction();
ft.setCustomAnimations(R.anim.slide_in_left, R.anim.slide_out_right);

DetailsFragment newFragment = DetailsFragment.newInstance();

ft.replace(R.id.details_fragment_container, newFragment, "detailFragment");

// Start the animated transition.
ft.commit();

To achieve the same thing with hiding or showing a fragment you'd simply call ft.show or ft.hide, passing in the Fragment you wish to show or hide respectively.

For reference, the XML animation definitions would use the objectAnimator tag. An example of slide_in_left might look something like this:

<?xml version="1.0" encoding="utf-8"?>
<set>
  <objectAnimator xmlns:android="http://schemas.android.com/apk/res/android"
    android:propertyName="x" 
    android:valueType="floatType"
    android:valueFrom="-1280"
    android:valueTo="0" 
    android:duration="500"/>
</set>

DECLARE @seconds AS int = 896434;
SELECT
    CONVERT(varchar, (@seconds / 86400))                --Days
    + ':' +
    CONVERT(varchar, DATEADD(ss, @seconds, 0), 108);    --Hours, Minutes, Seconds

Outputs:

10:09:00:34

I solved my problem using some css into the web page.

You are running Python 2, not Python 3. For this to work in Python 2, use raw_input.

input_variable = raw_input ("Enter your name: ")
print ("your name is" + input_variable)

You shall proceed with ent.delete(0,"end") instead of using 'END', use 'end' inside quotation.

 secret = randrange(1,100)
print(secret)
def res(real, secret):
    if secret==eval(real):
        showinfo(message='that is right!')
    real.delete(0, END)

def guess():
    ge = Tk()
    ge.title('guessing game')

    Label(ge, text="what is your guess:").pack(side=TOP)

    ent = Entry(ge)
    ent.pack(side=TOP)

    btn=Button(ge, text="Enter", command=lambda: res(ent.get(),secret))
    btn.pack(side=LEFT)

    ge.mainloop()

This shall solve your problem

You want to check if an object is NULL/empty. Being NULL and empty are not the same. Like Justin and Brian have already mentioned, in C++ NULL is an assignment you'd typically associate with pointers. You can overload operator= perhaps, but think it through real well if you actually want to do this. Couple of other things:

1. In C++ NULL pointer is very different to pointer pointing to an 'empty' object.
2. Why not have a bool IsEmpty() method that returns true if an object's variables are reset to some default state? Guess that might bypass the NULL usage.
3. Having something like A* p = new A; ... p = NULL; is bad (no delete p) unless you can ensure your code will be garbage collected. If anything, this'd lead to memory leaks and with several such leaks there's good chance you'd have slow code.
4. You may want to do this class Null {}; Null _NULL; and then overload operator= and operator!= of other classes depending on your situation.

Perhaps you should post us some details about the context to help you better with option 4.

The node-csv project that you are referencing is completely sufficient for the task of transforming each row of a large portion of CSV data, from the docs at: http://csv.adaltas.com/transform/:

csv()
  .from('82,Preisner,Zbigniew\n94,Gainsbourg,Serge')
  .to(console.log)
  .transform(function(row, index, callback){
    process.nextTick(function(){
      callback(null, row.reverse());
    });
});

From my experience, I can say that it is also a rather fast implementation, I have been working with it on data sets with near 10k records and the processing times were at a reasonable tens-of-milliseconds level for the whole set.

Rearding jurka's stream based solution suggestion: node-csv IS stream based and follows the Node.js' streaming API.

Depending on how large your array of int will be, you will get much better performance if you use collections and .contains rather than iterating over the array one element at a time:

import static org.junit.Assert.assertTrue;
import java.util.HashSet;

import org.junit.Before;
import org.junit.Test;

public class IntLookupTest {

int numberOfInts = 500000;
int toFind = 200000;
int[] array;

HashSet<Integer> intSet;

@Before
public void initializeArrayAndSet() {
    array = new int[numberOfInts];
    intSet = new HashSet<Integer>();
    for(int i = 0; i < numberOfInts; i++) {
        array[i] = i;
        intSet.add(i);
    }
}

@Test
public void lookupUsingCollections() {
    assertTrue(intSet.contains(toFind));
}

@Test
public void iterateArray() {
    assertTrue(contains(array, toFind));

}

public boolean contains(final int[] array, final int key) {
    for (final int i : array) {
        if (i == key) {
            return true;
        }
    }
    return false;
}
}

The problem is that you used the select option, this is where you went wrong. Select signifies that a textbox or textArea has a focus. What you need to do is use change. "Fires when a new choice is made in a select element", also used like blur when moving away from a textbox or textArea.

function start(){
      document.getElementById("activitySelector").addEventListener("change", addActivityItem, false);
      }

function addActivityItem(){
      //option is selected
      alert("yeah");
}

window.addEventListener("load", start, false);

If you can use C#6 or higher, you can benefit from Interpolated Strings and rewrite @Ari Roth's solution like this:

C# 6 :

public static class ColorConverterExtensions
{
    public static string ToHexString(this Color c) => $"#{c.R:X2}{c.G:X2}{c.B:X2}";

    public static string ToRgbString(this Color c) => $"RGB({c.R}, {c.G}, {c.B})";
}

Also:

• I add the keyword this to use them as extensions methods.
• We can use the type keyword string instead of the class name.
• We can use lambda syntax.
• I rename them to be more explicit for my taste.

Based on gnibbler top voted answer (Nov 20 '09 at 0:27): this class add head() and tail() method to file object.

class File(file):
    def head(self, lines_2find=1):
        self.seek(0)                            #Rewind file
        return [self.next() for x in xrange(lines_2find)]

    def tail(self, lines_2find=1):  
        self.seek(0, 2)                         #go to end of file
        bytes_in_file = self.tell()             
        lines_found, total_bytes_scanned = 0, 0
        while (lines_2find+1 > lines_found and
               bytes_in_file > total_bytes_scanned): 
            byte_block = min(1024, bytes_in_file-total_bytes_scanned)
            self.seek(-(byte_block+total_bytes_scanned), 2)
            total_bytes_scanned += byte_block
            lines_found += self.read(1024).count('\n')
        self.seek(-total_bytes_scanned, 2)
        line_list = list(self.readlines())
        return line_list[-lines_2find:]

Usage:

f = File('path/to/file', 'r')
f.head(3)
f.tail(3)

If you downloaded mySQL using a DMG (easiest way to download found here http://dev.mysql.com/downloads/mysql/) in Terminal try: cd /usr/local/

When you type ls you should see mysql-YOUR-VERSION. You will also see mysql which is the installation directory.

Source: http://geeksww.com/tutorials/database_management_systems/mysql/installation/how_to_download_and_install_mysql_on_mac_os_x.php

Sometimes we have to use loops, for example, when we don't know how many iterations we need to get the result. Take while loops as an example. Below are methods you absolutely should avoid:

a=numeric(0)
b=1
system.time(
  {
    while(b<=1e5){
      b=b+1
      a<-c(a,pi)
    }
  }
)
# user  system elapsed 
# 13.2     0.0    13.2 

a=numeric(0)
b=1
system.time(
  {
    while(b<=1e5){
      b=b+1
      a<-append(a,pi)
    }
  }
)
# user  system elapsed 
# 11.06    5.72   16.84 

These are very inefficient because R copies the vector every time it appends.

The most efficient way to append is to use index. Note that this time I let it iterate 1e7 times, but it's still much faster than c.

a=numeric(0)
system.time(
  {
    while(length(a)<1e7){
      a[length(a)+1]=pi
    }
  }
)
# user  system elapsed 
# 5.71    0.39    6.12  

This is acceptable. And we can make it a bit faster by replacing [ with [[.

a=numeric(0)
system.time(
  {
    while(length(a)<1e7){
      a[[length(a)+1]]=pi
    }
  }
)
# user  system elapsed 
# 5.29    0.38    5.69   

Maybe you already noticed that length can be time consuming. If we replace length with a counter:

a=numeric(0)
b=1
system.time(
  {
    while(b<=1e7){
      a[[b]]=pi
      b=b+1
    }
  }
)
# user  system elapsed 
# 3.35    0.41    3.76

As other users mentioned, pre-allocating the vector is very helpful. But this is a trade-off between speed and memory usage if you don't know how many loops you need to get the result.

a=rep(NaN,2*1e7)
b=1
system.time(
  {
    while(b<=1e7){
      a[[b]]=pi
      b=b+1
    }
    a=a[!is.na(a)]
  }
)
# user  system elapsed 
# 1.57    0.06    1.63 

An intermediate method is to gradually add blocks of results.

a=numeric(0)
b=0
step_count=0
step=1e6
system.time(
  {
    repeat{
      a_step=rep(NaN,step)
      for(i in seq_len(step)){
        b=b+1
        a_step[[i]]=pi
        if(b>=1e7){
          a_step=a_step[1:i]
          break
        }
      }
      a[(step_count*step+1):b]=a_step
      if(b>=1e7) break
      step_count=step_count+1
    }
  }
)
#user  system elapsed 
#1.71    0.17    1.89

You could use Role Strategy plugin for that purpose. It works like a charm, just setup some roles and assign them. Even on project-specific level.

C# just does a shallow copy when it passes by value unless the object in question executes ICloneable (which apparently the List class does not).

What this means is that it copies the List itself, but the references to the objects inside the list remain the same; that is, the pointers continue to reference the same objects as the original List.

If you change the values of the things your new List references, you change the original List also (since it is referencing the same objects). However, you then change what myList references entirely, to a new List, and now only the original List is referencing those integers.

Read the Passing Reference-Type Parameters section from this MSDN article on "Passing Parameters" for more information.

"How do I Clone a Generic List in C#" from StackOverflow talks about how to make a deep copy of a List.

replaceAll(search, replaceWith) [MDN]

 ".a.b.c.".replaceAll('.', ' ')
 // result: " a b c "

 // Using RegEx. You MUST use a global RegEx.
 ".a.b.c.".replaceAll(/\./g, ' ')
 // result: " a b c "
    

replaceAll() replaces ALL occurrences of search with replaceWith.

It's actually the same as using replace() [MDN] with a global regex(*), merely replaceAll() is a bit more readable in my view.

(*) Meaning it'll match all occurrences.

Important(!) if you choose regex:

when using a regexp you have to set the global ("g") flag; otherwise, it will throw a TypeError: "replaceAll must be called with a global RegExp".

You probably need to do a git stash before you git pull, this is because it is reading your old config file. So do:

git stash
git pull
git commit -am <"say first commit">
git push

Also see git-stash(1) Manual Page.

Put sleep. It will work. I have tried. The reason is that the page wasn't loaded yet. Check this question to know how to wait for load - Wait for page load in Selenium

from collections import Counter
x = array( [1,1,1,2,2,2,5,25,1,1] )
mode = counter.most_common(1)[0][0]

Here's a simple explanation. You need to transfer 100 bucks from account A to account B. You can either do:

accountA -= 100;
accountB += 100;

or

accountB += 100;
accountA -= 100;

If something goes wrong between the first and the second operation in the pair you have a problem - either 100 bucks have disappeared, or they have appeared out of nowhere.

A transaction is a mechanism that allows you to mark a group of operations and execute them in such a way that either they all execute (commit), or the system state will be as if they have not started to execute at all (rollback).

beginTransaction;
accountB += 100;
accountA -= 100;
commitTransaction;

will either transfer 100 bucks or leave both accounts in the initial state.

You need to use the CONCAT() function in MySQL for string concatenation:

UPDATE categories SET code = CONCAT(code, '_standard') WHERE id = 1;

Here Is working fiddle

The correct method is #2. You used the section tag to define a section of your document. From the specs http://www.w3.org/TR/html5/sections.html:

The section element is not a generic container element. When an element is needed for styling purposes or as a convenience for scripting, authors are encouraged to use the div element instead

This is example code I have written for you to understand this concept:

var foo = 5; 
bar = 2;     
fooba = 3;

// Execute an anonymous function
(function() {    
    bar = 100;             //overwrites global scope bar
    var foo = 4;           //a new foo variable is created in this' function's scope
    var fooba = 900;       //same as above
    document.write(foo);   //prints 4
    document.write(bar);   //prints 100
    document.write(fooba); //prints 900
})();

document.write('<br/>');
document.write('<br/>');
document.write(foo);       //prints 5
document.write(bar);       //prints 100
document.write(fooba);     //prints 3

All of the answers is true.This is another way. And I like this One

SqlCommand cmd = conn.CreateCommand()

This has worked for me. At first I've created only the database, no predefined table I created.

from platform import python_version
print(python_version())

df=pd.read_csv(path)
df.head()


!conda install sqlalchemy
!conda install pymysql

pd.__version__
    '0.24.2'

sqlalchemy.__version__
'1.3.20'

restarted the Kernel after installation.

from sqlalchemy import create_engine
engine = create_engine('mysql+pymysql://USER:PASSWORD@HOST:PORT/DATABASE_NAME', echo=False)

try:
df.to_sql(name='glasstable',con=engine,index=False, if_exists='replace')
print('Sucessfully written to Database!!!')

except Exception as e:
    print(e)

DateTime.Now returns a value of data type Date. Date variables display dates according to the short date format and time format set on your computer.

They may be formatted as a string for display in any valid date format by the Format function as mentioned in aother answers

Format(DateTime.Now, "yyyy-MM-dd hh:mm:ss")

If you try to count the number of rows in the already autofiltered range like this:

Rowz = rnData.SpecialCells(xlCellTypeVisible).Rows.Count

It will only count the number of rows in the first contiguous visible area of the autofiltered range. E.g. if the autofilter range is rows 1 through 10 and rows 3, 5, 6, 7, and 9 are filtered, four rows are visible (rows 2, 4, 8, and 10), but it would return 2 because the first contiguous visible range is rows 1 (the header row) and 2.

A more accurate alternative is this (assuming that ws contains the worksheet with the filtered data):

Rowz = ws.AutoFilter.Range.Columns(1).SpecialCells(xlCellTypeVisible).Cells.Count - 1

We have to subtract 1 to remove the header row. We need to include the header row in our counted range because SpecialCells will throw an error if no cells are found, which we want to avoid.

The Cells property will give you an accurate count even if the Range has multiple Areas, unlike the Rows property. So we just take the first column of the autofilter range and count the number of visible cells.

I'll just post the code to do this using the fluent API mapping.

public class User {
    public int UserID { get; set; }
    public string Username { get; set; }
    public string Password { get; set; }

    public ICollection<UserEmail> UserEmails { get; set; }
}

public class Email {
    public int EmailID { get; set; }
    public string Address { get; set; }

    public ICollection<UserEmail> UserEmails { get; set; }
}

public class UserEmail {
    public int UserID { get; set; }
    public int EmailID { get; set; }
    public bool IsPrimary { get; set; }
}

On your DbContext derived class you could do this:

public class MyContext : DbContext {
    protected override void OnModelCreating(DbModelBuilder builder) {
        // Primary keys
        builder.Entity<User>().HasKey(q => q.UserID);
        builder.Entity<Email>().HasKey(q => q.EmailID);
        builder.Entity<UserEmail>().HasKey(q => 
            new { 
                q.UserID, q.EmailID
            });

        // Relationships
        builder.Entity<UserEmail>()
            .HasRequired(t => t.Email)
            .WithMany(t => t.UserEmails)
            .HasForeignKey(t => t.EmailID)

        builder.Entity<UserEmail>()
            .HasRequired(t => t.User)
            .WithMany(t => t.UserEmails)
            .HasForeignKey(t => t.UserID)
    }
}

It has the same effect as the accepted answer, with a different approach, which is no better nor worse.

The problem comes from the fact that np.isnan() does not handle string values correctly. For example, if you do:

np.isnan("A")
TypeError: ufunc 'isnan' not supported for the input types, and the inputs could not be safely coerced to any supported types according to the casting rule ''safe''

However the pandas version pd.isnull() works for numeric and string values:

pd.isnull("A")
> False

pd.isnull(3)
> False

pd.isnull(np.nan)
> True

pd.isnull(None)
> True

The difference between "" and () is:

With "" you are not calling anything.
With () you are calling a sub.

Example with sub:

Sub = MsgBox("Msg",vbYesNo,vbCritical,"Title")
Select Case Sub
     Case = vbYes
          MsgBox"You said yes"
     Case = vbNo
          MsgBox"You said no"
 End Select

vs Normal:

 MsgBox"This is normal"

do you use Bash? Go to the file .bashrc in your home directory and set the variable, then export it.

DISPLAY=localhost:0.0 ; export DISPLAY

you can use /etc/bashrc if you want to do it for all the users.

You may also want to look in ~/.bash_profile and /etc/profile

EDIT:

function get_xserver ()
{
    case $TERM in
       xterm )
            XSERVER=$(who am i | awk '{print $NF}' | tr -d ')''(' )    
            XSERVER=${XSERVER%%:*}
            ;;
        aterm | rxvt)           
            ;;
    esac  
}

if [ -z ${DISPLAY:=""} ]; then
    get_xserver
    if [[ -z ${XSERVER}  || ${XSERVER} == $(hostname) || \
      ${XSERVER} == "unix" ]]; then 
        DISPLAY=":0.0"          # Display on local host.
    else
        DISPLAY=${XSERVER}:0.0  # Display on remote host.
    fi
fi

export DISPLAY

Use the HEREDOC syntax. You can mix single and double quotes, variables and even function calls with unaltered / unescaped html markup.

echo <<<MYTAG
  <tr><td> <input type="hidden" name="type" value="$var1" ></td></tr>
  <tr><td> <input type="hidden" name="type" value="$var2" ></td></tr>
  <tr><td> <input type="hidden" name="type" value="$var3" ></td></tr>
  <tr><td> <input type="hidden" name="type" value="$var4" ></td></tr>
MYTAG;

You need to add uppercase L at the end like so

long i = 12345678910L;

Same goes true for float with 3.0f

Which should answer both of your questions

Using two extension methods, this becomes very easy:

public static class Ext
{
    public static void SetText(this RichTextBox richTextBox, string text)
    {
        richTextBox.Document.Blocks.Clear();
        richTextBox.Document.Blocks.Add(new Paragraph(new Run(text)));
    }

    public static string GetText(this RichTextBox richTextBox)
    {
        return new TextRange(richTextBox.Document.ContentStart,
            richTextBox.Document.ContentEnd).Text;
    }
}

I don't have grep or other unix on my box but this worked from VSCode's terminal:

git branch -d $(git branch).trim()

I use the lowercase d so it won't delete unmerged branches.

I was also on master when I did it, so * master doesn't exist so it didn't attempt deleting master.

Swift 4.2 version:

let indexPath:IndexPath = IndexPath(row: 0, section: 0)
self.tableView.scrollToRow(at: indexPath, at: .none, animated: true)

Enum: These are the available tableView scroll positions - here for reference. You don't need to include this section in your code.

public enum UITableViewScrollPosition : Int {

case None
case Top
case Middle
case Bottom
}

DidSelectRow:

func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {

    let theCell:UITableViewCell? = tableView.cellForRowAtIndexPath(indexPath)

    if let theCell = theCell {
        var tableViewCenter:CGPoint = tableView.contentOffset
        tableViewCenter.y += tableView.frame.size.height/2

        tableView.contentOffset = CGPointMake(0, theCell.center.y-65)
        tableView.reloadData()
    }

}

You could also put non-breaking spaces (&nbsp;) in lieu of the spaces so that they're forced to stay together.

How do I wrap this line of text

The official tutorial discusses deploying an app to production. One option is to use Waitress, a production WSGI server. Other servers include Gunicorn and uWSGI.

When running publicly rather than in development, you should not use the built-in development server (flask run). The development server is provided by Werkzeug for convenience, but is not designed to be particularly efficient, stable, or secure.

Instead, use a production WSGI server. For example, to use Waitress, first install it in the virtual environment:

$ pip install waitress

You need to tell Waitress about your application, but it doesn’t use FLASK_APP like flask run does. You need to tell it to import and call the application factory to get an application object.

$ waitress-serve --call 'flaskr:create_app'
Serving on http://0.0.0.0:8080

Or you can use waitress.serve() in the code instead of using the CLI command.

from flask import Flask

app = Flask(__name__)

@app.route("/")
def index():
    return "<h1>Hello!</h1>"

if __name__ == "__main__":
    from waitress import serve
    serve(app, host="0.0.0.0", port=8080)

$ python hello.py

This can also happen due to the bad unzipping process of SDK.It Happend to me. Dont use inbuilt windows unzip process. use WINRAR software for unzipping sdk

You cannot session_start(); when your buffer has already been partly sent.

This mean, if your script already sent informations (something you want, or an error report) to the client, session_start() will fail.

The problem here is that in your code the program is calling 'null.length()' which is not defined if the argument passed to the function is null. That's why the exception is thrown.

You likely have other files (such as the default configuration) located in /etc/nginx/sites-enabled that needs to be removed.

This issue is caused by a repeat of the default_server parameter supplied to one or more listen directives in your files. You'll likely find this conflicting directive reads something similar to:

listen 80 default_server;

As the nginx core module documentation for listen states:

The default_server parameter, if present, will cause the server to become the default server for the specified address:port pair. If none of the directives have the default_server parameter then the first server with the address:port pair will be the default server for this pair.

This means that there must be another file or server block defined in your configuration with default_server set for port 80. nginx is encountering that first before your mysite.com file so try removing or adjusting that other configuration.

If you are struggling to find where these directives and parameters are set, try a search like so:

grep -R default_server /etc/nginx

Pickling will serialize your list (convert it, and it's entries to a unique byte string), so you can save it to disk. You can also use pickle to retrieve your original list, loading from the saved file.

So, first build a list, then use pickle.dump to send it to a file...

In summary, valid characters in the text are:

• tab, line-feed and carriage-return.
• all non-control characters are valid except & and <.
• > is not valid if following ]].

Sections 2.2 and 2.4 of the XML specification provide the answer in detail:

Characters

Legal characters are tab, carriage return, line feed, and the legal characters of Unicode and ISO/IEC 10646

Character data

The ampersand character (&) and the left angle bracket (<) must not appear in their literal form, except when used as markup delimiters, or within a comment, a processing instruction, or a CDATA section. If they are needed elsewhere, they must be escaped using either numeric character references or the strings " & " and " < " respectively. The right angle bracket (>) may be represented using the string " > ", and must, for compatibility, be escaped using either " > " or a character reference when it appears in the string " ]]> " in content, when that string is not marking the end of a CDATA section.

Since the question asks for an available data structure, a tree can be constructed from lists or arrays:

Object[] tree = new Object[2];
tree[0] = "Hello";
{
  Object[] subtree = new Object[2];
  subtree[0] = "Goodbye";
  subtree[1] = "";
  tree[1] = subtree;
}

instanceof can be used to determine whether an element is a subtree or a terminal node.

ApplicationContext (Root Application Context) : Every Spring MVC web application has an applicationContext.xml file which is configured as the root of context configuration. Spring loads this file and creates an applicationContext for the entire application. This file is loaded by the ContextLoaderListener which is configured as a context param in web.xml file. And there will be only one applicationContext per web application.

WebApplicationContext : WebApplicationContext is a web aware application context i.e. it has servlet context information. A single web application can have multiple WebApplicationContext and each Dispatcher servlet (which is the front controller of Spring MVC architecture) is associated with a WebApplicationContext. The webApplicationContext configuration file *-servlet.xml is specific to a DispatcherServlet. And since a web application can have more than one dispatcher servlet configured to serve multiple requests, there can be more than one webApplicationContext file per web application.

As others have mentioned this can be caused when some firewalls and proxies prevent access to pages containing a large amount of ViewState data.

ASP.NET 2.0 introduced the ViewState Chunking mechanism which breaks the ViewState up into manageable chunks, allowing the ViewState to pass through the proxy / firewall without issue.

To enable this feature simply add the following line to your web.config file.

<pages maxPageStateFieldLength="4000">

This should not be used as an alternative to reducing your ViewState size but it can be an effective backstop against the "Invalid length for a Base-64 char array" error resulting from aggressive proxies and the like.

Since version 0.18.1 the .loc method accepts a callable for selection. Together with lambda functions you can create very flexible chainable filters:

import numpy as np
import pandas as pd

df = pd.DataFrame(np.random.randint(0,100,size=(100, 4)), columns=list('ABCD'))
df.loc[lambda df: df.A == 80]  # equivalent to df[df.A == 80] but chainable

df.sort_values('A').loc[lambda df: df.A > 80].loc[lambda df: df.B > df.A]

If all you're doing is filtering, you can also omit the .loc.

On Debian i found out to run on port 80 you need to issue the command as root i.e

sudo node app.js

I hope it helps

Try

import platform
platform.python_version()

Should give you a string like "2.3.1". If this is not exactly waht you want there is a rich set of data available through the "platform" build-in. What you want should be in there somewhere.

Yeah. Try this.. lazy evaluation should prohibit the second part of the condition from evaluating when the first part is false/null:

var someval = document.getElementById('something')
if (someval && someval.value <> '') {
